-<h1 align="center">SQLite Source Repository</h1>
-
-This repository contains the complete source code for the SQLite database
-engine.  Some test scripts are also included.  However, many other test scripts
-and most of the documentation are managed separately.
-
-SQLite [does not use Git](https://sqlite.org/whynotgit.html).
-If you are reading this on GitHub, then you are looking at an
-unofficial mirror. See <https://sqlite.org/src> for the official
-repository.
-
-## Obtaining The Code
-
-SQLite sources are managed using the
-[Fossil](https://www.fossil-scm.org/), a distributed version control system
-that was specifically designed to support SQLite development.
-If you do not want to use Fossil, you can download tarballs or ZIP
-archives or [SQLite archives](https://sqlite.org/cli.html#sqlar) as follows:
-
-  *  Lastest trunk check-in as
-     [Tarball](https://www.sqlite.org/src/tarball/sqlite.tar.gz),
-     [ZIP-archive](https://www.sqlite.org/src/zip/sqlite.zip), or
-     [SQLite-archive](https://www.sqlite.org/src/sqlar/sqlite.sqlar).
-
-  *  Latest release as
-     [Tarball](https://www.sqlite.org/src/tarball/sqlite.tar.gz?r=release),
-     [ZIP-archive](https://www.sqlite.org/src/zip/sqlite.zip?r=release), or
-     [SQLite-archive](https://www.sqlite.org/src/sqlar/sqlite.sqlar?r=release).
-
-  *  For other check-ins, substitute an appropriate branch name or
-     tag or hash prefix for "release" in the URLs of the previous
-     bullet.  Or browse the [timeline](https://www.sqlite.org/src/timeline)
-     to locate the check-in desired, click on its information page link,
-     then click on the "Tarball" or "ZIP Archive" links on the information
-     page.
-
-If you do want to use Fossil to check out the source tree, 
-first install Fossil version 2.0 or later.
-(Source tarballs and precompiled binaries available
-[here](https://www.fossil-scm.org/fossil/uv/download.html).  Fossil is
-a stand-alone program.  To install, simply download or build the single 
-executable file and put that file someplace on your $PATH.)
-Then run commands like this:
-
-        mkdir ~/sqlite
-        cd ~/sqlite
-        fossil clone https://www.sqlite.org/src sqlite.fossil
-        fossil open sqlite.fossil
-    
-After setting up a repository using the steps above, you can always
-update to the lastest version using:
-
-        fossil update trunk   ;# latest trunk check-in
-        fossil update release ;# latest official release
-
-Or type "fossil ui" to get a web-based user interface.
-
-## Compiling
-
-First create a directory in which to place
-the build products.  It is recommended, but not required, that the
-build directory be separate from the source directory.  Cd into the
-build directory and then from the build directory run the configure
-script found at the root of the source tree.  Then run "make".
-
-For example:
-
-        tar xzf sqlite.tar.gz    ;#  Unpack the source tree into "sqlite"
-        mkdir bld                ;#  Build will occur in a sibling directory
-        cd bld                   ;#  Change to the build directory
-        ../sqlite/configure      ;#  Run the configure script
-        make                     ;#  Run the makefile.
-        make sqlite3.c           ;#  Build the "amalgamation" source file
-        make test                ;#  Run some tests (requires Tcl)
-
-See the makefile for additional targets.
-
-The configure script uses autoconf 2.61 and libtool.  If the configure
-script does not work out for you, there is a generic makefile named
-"Makefile.linux-gcc" in the top directory of the source tree that you
-can copy and edit to suit your needs.  Comments on the generic makefile
-show what changes are needed.
-
-## Using MSVC
-
-On Windows, all applicable build products can be compiled with MSVC.
-First open the command prompt window associated with the desired compiler
-version (e.g. "Developer Command Prompt for VS2013").  Next, use NMAKE
-with the provided "Makefile.msc" to build one of the supported targets.
-
-For example:
-
-        mkdir bld
-        cd bld
-        nmake /f Makefile.msc TOP=..\sqlite
-        nmake /f Makefile.msc sqlite3.c TOP=..\sqlite
-        nmake /f Makefile.msc sqlite3.dll TOP=..\sqlite
-        nmake /f Makefile.msc sqlite3.exe TOP=..\sqlite
-        nmake /f Makefile.msc test TOP=..\sqlite
-
-There are several build options that can be set via the NMAKE command
-line.  For example, to build for WinRT, simply add "FOR_WINRT=1" argument
-to the "sqlite3.dll" command line above.  When debugging into the SQLite
-code, adding the "DEBUG=1" argument to one of the above command lines is
-recommended.
-
-SQLite does not require [Tcl](http://www.tcl.tk/) to run, but a Tcl installation
-is required by the makefiles (including those for MSVC).  SQLite contains
-a lot of generated code and Tcl is used to do much of that code generation.
-
-## Source Code Tour
-
-Most of the core source files are in the **src/** subdirectory.  The
-**src/** folder also contains files used to build the "testfixture" test
-harness. The names of the source files used by "testfixture" all begin
-with "test".
-The **src/** also contains the "shell.c" file
-which is the main program for the "sqlite3.exe"
-[command-line shell](https://sqlite.org/cli.html) and
-the "tclsqlite.c" file which implements the
-[Tcl bindings](https://sqlite.org/tclsqlite.html) for SQLite.
-(Historical note:  SQLite began as a Tcl
-extension and only later escaped to the wild as an independent library.)
-
-Test scripts and programs are found in the **test/** subdirectory.
-Addtional test code is found in other source repositories.
-See [How SQLite Is Tested](http://www.sqlite.org/testing.html) for
-additional information.
-
-The **ext/** subdirectory contains code for extensions.  The
-Full-text search engine is in **ext/fts3**.  The R-Tree engine is in
-**ext/rtree**.  The **ext/misc** subdirectory contains a number of
-smaller, single-file extensions, such as a REGEXP operator.
-
-The **tool/** subdirectory contains various scripts and programs used
-for building generated source code files or for testing or for generating
-accessory programs such as "sqlite3_analyzer(.exe)".
-
-### Generated Source Code Files
-
-Several of the C-language source files used by SQLite are generated from
-other sources rather than being typed in manually by a programmer.  This
-section will summarize those automatically-generated files.  To create all
-of the automatically-generated files, simply run "make target&#95;source".
-The "target&#95;source" make target will create a subdirectory "tsrc/" and
-fill it with all the source files needed to build SQLite, both
-manually-edited files and automatically-generated files.
-
-The SQLite interface is defined by the **sqlite3.h** header file, which is
-generated from src/sqlite.h.in, ./manifest.uuid, and ./VERSION.  The
-[Tcl script](http://www.tcl.tk) at tool/mksqlite3h.tcl does the conversion.
-The manifest.uuid file contains the SHA3 hash of the particular check-in
-and is used to generate the SQLITE\_SOURCE\_ID macro.  The VERSION file
-contains the current SQLite version number.  The sqlite3.h header is really
-just a copy of src/sqlite.h.in with the source-id and version number inserted
-at just the right spots. Note that comment text in the sqlite3.h file is
-used to generate much of the SQLite API documentation.  The Tcl scripts
-used to generate that documentation are in a separate source repository.
-
-The SQL language parser is **parse.c** which is generate from a grammar in
-the src/parse.y file.  The conversion of "parse.y" into "parse.c" is done
-by the [lemon](./doc/lemon.html) LALR(1) parser generator.  The source code
-for lemon is at tool/lemon.c.  Lemon uses the tool/lempar.c file as a
-template for generating its parser.
-
-Lemon also generates the **parse.h** header file, at the same time it
-generates parse.c. But the parse.h header file is
-modified further (to add additional symbols) using the ./addopcodes.tcl
-Tcl script.
-
-The **opcodes.h** header file contains macros that define the numbers
-corresponding to opcodes in the "VDBE" virtual machine.  The opcodes.h
-file is generated by the scanning the src/vdbe.c source file.  The
-Tcl script at ./mkopcodeh.tcl does this scan and generates opcodes.h.
-A second Tcl script, ./mkopcodec.tcl, then scans opcodes.h to generate
-the **opcodes.c** source file, which contains a reverse mapping from
-opcode-number to opcode-name that is used for EXPLAIN output.
-
-The **keywordhash.h** header file contains the definition of a hash table
-that maps SQL language keywords (ex: "CREATE", "SELECT", "INDEX", etc.) into
-the numeric codes used by the parse.c parser.  The keywordhash.h file is
-generated by a C-language program at tool mkkeywordhash.c.
-
-The **pragma.h** header file contains various definitions used to parse
-and implement the PRAGMA statements.  The header is generated by a
-script **tool/mkpragmatab.tcl**. If you want to add a new PRAGMA, edit
-the **tool/mkpragmatab.tcl** file to insert the information needed by the
-parser for your new PRAGMA, then run the script to regenerate the
-**pragma.h** header file.
-
-### The Amalgamation
-
-All of the individual C source code and header files (both manually-edited
-and automatically-generated) can be combined into a single big source file
-**sqlite3.c** called "the amalgamation".  The amalgamation is the recommended
-way of using SQLite in a larger application.  Combining all individual
-source code files into a single big source code file allows the C compiler
-to perform more cross-procedure analysis and generate better code.  SQLite
-runs about 5% faster when compiled from the amalgamation versus when compiled
-from individual source files.
-
-The amalgamation is generated from the tool/mksqlite3c.tcl Tcl script.
-First, all of the individual source files must be gathered into the tsrc/
-subdirectory (using the equivalent of "make target_source") then the
-tool/mksqlite3c.tcl script is run to copy them all together in just the
-right order while resolving internal "#include" references.
-
-The amalgamation source file is more than 200K lines long.  Some symbolic
-debuggers (most notably MSVC) are unable to deal with files longer than 64K
-lines.  To work around this, a separate Tcl script, tool/split-sqlite3c.tcl,
-can be run on the amalgamation to break it up into a single small C file
-called **sqlite3-all.c** that does #include on about seven other files
-named **sqlite3-1.c**, **sqlite3-2.c**, ..., **sqlite3-7.c**.  In this way,
-all of the source code is contained within a single translation unit so
-that the compiler can do extra cross-procedure optimization, but no
-individual source file exceeds 32K lines in length.
-
-## How It All Fits Together
-
-SQLite is modular in design.
-See the [architectural description](http://www.sqlite.org/arch.html)
-for details. Other documents that are useful in
-(helping to understand how SQLite works include the
-[file format](http://www.sqlite.org/fileformat2.html) description,
-the [virtual machine](http://www.sqlite.org/opcode.html) that runs
-prepared statements, the description of
-[how transactions work](http://www.sqlite.org/atomiccommit.html), and
-the [overview of the query planner](http://www.sqlite.org/optoverview.html).
-
-Years of effort have gone into optimizating SQLite, both
-for small size and high performance.  And optimizations tend to result in
-complex code.  So there is a lot of complexity in the current SQLite
-implementation.  It will not be the easiest library in the world to hack.
-
-Key files:
-
-  *  **sqlite.h.in** - This file defines the public interface to the SQLite
-     library.  Readers will need to be familiar with this interface before
-     trying to understand how the library works internally.
-
-  *  **sqliteInt.h** - this header file defines many of the data objects
-     used internally by SQLite.  In addition to "sqliteInt.h", some
-     subsystems have their own header files.
-
-  *  **parse.y** - This file describes the LALR(1) grammar that SQLite uses
-     to parse SQL statements, and the actions that are taken at each step
-     in the parsing process.
-
-  *  **vdbe.c** - This file implements the virtual machine that runs
-     prepared statements.  There are various helper files whose names
-     begin with "vdbe".  The VDBE has access to the vdbeInt.h header file
-     which defines internal data objects.  The rest of SQLite interacts
-     with the VDBE through an interface defined by vdbe.h.
-
-  *  **where.c** - This file (together with its helper files named
-     by "where*.c") analyzes the WHERE clause and generates
-     virtual machine code to run queries efficiently.  This file is
-     sometimes called the "query optimizer".  It has its own private
-     header file, whereInt.h, that defines data objects used internally.
-
-  *  **btree.c** - This file contains the implementation of the B-Tree
-     storage engine used by SQLite.  The interface to the rest of the system
-     is defined by "btree.h".  The "btreeInt.h" header defines objects
-     used internally by btree.c and not published to the rest of the system.
-
-  *  **pager.c** - This file contains the "pager" implementation, the
-     module that implements transactions.  The "pager.h" header file
-     defines the interface between pager.c and the rest of the system.
-
-  *  **os_unix.c** and **os_win.c** - These two files implement the interface
-     between SQLite and the underlying operating system using the run-time
-     pluggable VFS interface.
-
-  *  **shell.c.in** - This file is not part of the core SQLite library.  This
-     is the file that, when linked against sqlite3.a, generates the
-     "sqlite3.exe" command-line shell.  The "shell.c.in" file is transformed
-     into "shell.c" as part of the build process.
-
-  *  **tclsqlite.c** - This file implements the Tcl bindings for SQLite.  It
-     is not part of the core SQLite library.  But as most of the tests in this
-     repository are written in Tcl, the Tcl language bindings are important.
-
-  *  **test*.c** - Files in the src/ folder that begin with "test" go into
-     building the "testfixture.exe" program.  The testfixture.exe program is
-     an enhanced Tcl shell.  The testfixture.exe program runs scripts in the
-     test/ folder to validate the core SQLite code.  The testfixture program
-     (and some other test programs too) is build and run when you type
-     "make test".
-
-  *  **ext/misc/json1.c** - This file implements the various JSON functions
-     that are build into SQLite.
-
-There are many other source files.  Each has a succinct header comment that
-describes its purpose and role within the larger system.

-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-Installation Instructions
-*************************
-

-Inc.
-
-   Copying and distribution of this file, with or without modification,
-are permitted in any medium without royalty provided the copyright
-notice and this notice are preserved.  This file is offered as-is,
-without warranty of any kind.
-
-Basic Installation
-==================
-
-   Briefly, the shell commands `./configure; make; make install' should
-configure, build, and install this package.  The following
-more-detailed instructions are generic; see the `README' file for
-instructions specific to this package.  Some packages provide this
-`INSTALL' file but do not implement all of the features documented
-below.  The lack of an optional feature in a given package is not
-necessarily a bug.  More recommendations for GNU packages can be found
-in *note Makefile Conventions: (standards)Makefile Conventions.
-
-   The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation.  It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions.  Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, and a
-file `config.log' containing compiler output (useful mainly for
-debugging `configure').
-
-   It can also use an optional file (typically called `config.cache'
-and enabled with `--cache-file=config.cache' or simply `-C') that saves
-the results of its tests to speed up reconfiguring.  Caching is
-disabled by default to prevent problems with accidental use of stale
-cache files.
-
-   If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release.  If you are using the cache, and at
-some point `config.cache' contains results you don't want to keep, you
-may remove or edit it.
-
-   The file `configure.ac' (or `configure.in') is used to create
-`configure' by a program called `autoconf'.  You need `configure.ac' if
-you want to change it or regenerate `configure' using a newer version
-of `autoconf'.
-
-   The simplest way to compile this package is:
-
-  1. `cd' to the directory containing the package's source code and type
-     `./configure' to configure the package for your system.
-
-     Running `configure' might take a while.  While running, it prints
-     some messages telling which features it is checking for.
-
-  2. Type `make' to compile the package.
-
-  3. Optionally, type `make check' to run any self-tests that come with
-     the package, generally using the just-built uninstalled binaries.
-
-  4. Type `make install' to install the programs and any data files and
-     documentation.  When installing into a prefix owned by root, it is
-     recommended that the package be configured and built as a regular
-     user, and only the `make install' phase executed with root
-     privileges.
-
-  5. Optionally, type `make installcheck' to repeat any self-tests, but
-     this time using the binaries in their final installed location.
-     This target does not install anything.  Running this target as a
-     regular user, particularly if the prior `make install' required
-     root privileges, verifies that the installation completed
-     correctly.
-
-  6. You can remove the program binaries and object files from the
-     source code directory by typing `make clean'.  To also remove the
-     files that `configure' created (so you can compile the package for
-     a different kind of computer), type `make distclean'.  There is
-     also a `make maintainer-clean' target, but that is intended mainly
-     for the package's developers.  If you use it, you may have to get
-     all sorts of other programs in order to regenerate files that came
-     with the distribution.
-
-  7. Often, you can also type `make uninstall' to remove the installed
-     files again.  In practice, not all packages have tested that
-     uninstallation works correctly, even though it is required by the
-     GNU Coding Standards.
-
-  8. Some packages, particularly those that use Automake, provide `make
-     distcheck', which can by used by developers to test that all other
-     targets like `make install' and `make uninstall' work correctly.
-     This target is generally not run by end users.
-
-Compilers and Options
-=====================
-
-   Some systems require unusual options for compilation or linking that
-the `configure' script does not know about.  Run `./configure --help'
-for details on some of the pertinent environment variables.
-
-   You can give `configure' initial values for configuration parameters
-by setting variables in the command line or in the environment.  Here
-is an example:
-
-     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
-
-   *Note Defining Variables::, for more details.
-
-Compiling For Multiple Architectures
-====================================
-
-   You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory.  To do this, you can use GNU `make'.  `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script.  `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.  This
-is known as a "VPATH" build.
-
-   With a non-GNU `make', it is safer to compile the package for one
-architecture at a time in the source code directory.  After you have
-installed the package for one architecture, use `make distclean' before
-reconfiguring for another architecture.
-
-   On MacOS X 10.5 and later systems, you can create libraries and
-executables that work on multiple system types--known as "fat" or
-"universal" binaries--by specifying multiple `-arch' options to the
-compiler but only a single `-arch' option to the preprocessor.  Like
-this:
-
-     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
-                 CPP="gcc -E" CXXCPP="g++ -E"
-
-   This is not guaranteed to produce working output in all cases, you
-may have to build one architecture at a time and combine the results
-using the `lipo' tool if you have problems.
-
-Installation Names
-==================
-
-   By default, `make install' installs the package's commands under
-`/usr/local/bin', include files under `/usr/local/include', etc.  You
-can specify an installation prefix other than `/usr/local' by giving
-`configure' the option `--prefix=PREFIX', where PREFIX must be an
-absolute file name.
-
-   You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files.  If you
-pass the option `--exec-prefix=PREFIX' to `configure', the package uses
-PREFIX as the prefix for installing programs and libraries.
-Documentation and other data files still use the regular prefix.
-
-   In addition, if you use an unusual directory layout you can give
-options like `--bindir=DIR' to specify different values for particular
-kinds of files.  Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.  In general, the
-default for these options is expressed in terms of `${prefix}', so that
-specifying just `--prefix' will affect all of the other directory
-specifications that were not explicitly provided.
-
-   The most portable way to affect installation locations is to pass the
-correct locations to `configure'; however, many packages provide one or
-both of the following shortcuts of passing variable assignments to the
-`make install' command line to change installation locations without
-having to reconfigure or recompile.
-
-   The first method involves providing an override variable for each
-affected directory.  For example, `make install
-prefix=/alternate/directory' will choose an alternate location for all
-directory configuration variables that were expressed in terms of
-`${prefix}'.  Any directories that were specified during `configure',
-but not in terms of `${prefix}', must each be overridden at install
-time for the entire installation to be relocated.  The approach of
-makefile variable overrides for each directory variable is required by
-the GNU Coding Standards, and ideally causes no recompilation.
-However, some platforms have known limitations with the semantics of
-shared libraries that end up requiring recompilation when using this
-method, particularly noticeable in packages that use GNU Libtool.
-
-   The second method involves providing the `DESTDIR' variable.  For
-example, `make install DESTDIR=/alternate/directory' will prepend
-`/alternate/directory' before all installation names.  The approach of
-`DESTDIR' overrides is not required by the GNU Coding Standards, and
-does not work on platforms that have drive letters.  On the other hand,
-it does better at avoiding recompilation issues, and works well even
-when some directory options were not specified in terms of `${prefix}'
-at `configure' time.
-
-Optional Features
-=================
-
-   If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-   Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System).  The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
-   For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-   Some packages offer the ability to configure how verbose the
-execution of `make' will be.  For these packages, running `./configure
---enable-silent-rules' sets the default to minimal output, which can be
-overridden with `make V=1'; while running `./configure
---disable-silent-rules' sets the default to verbose, which can be
-overridden with `make V=0'.
-
-Particular systems
-==================
-
-   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU
-CC is not installed, it is recommended to use the following options in
-order to use an ANSI C compiler:
-
-     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
-
-and if that doesn't work, install pre-built binaries of GCC for HP-UX.
-
-   HP-UX `make' updates targets which have the same time stamps as
-their prerequisites, which makes it generally unusable when shipped
-generated files such as `configure' are involved.  Use GNU `make'
-instead.
-
-   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
-parse its `<wchar.h>' header file.  The option `-nodtk' can be used as
-a workaround.  If GNU CC is not installed, it is therefore recommended
-to try
-
-     ./configure CC="cc"
-
-and if that doesn't work, try
-
-     ./configure CC="cc -nodtk"
-
-   On Solaris, don't put `/usr/ucb' early in your `PATH'.  This
-directory contains several dysfunctional programs; working variants of
-these programs are available in `/usr/bin'.  So, if you need `/usr/ucb'
-in your `PATH', put it _after_ `/usr/bin'.
-
-   On Haiku, software installed for all users goes in `/boot/common',
-not `/usr/local'.  It is recommended to use the following options:
-
-     ./configure --prefix=/boot/common
-
-Specifying the System Type
-==========================
-
-   There may be some features `configure' cannot figure out
-automatically, but needs to determine by the type of machine the package
-will run on.  Usually, assuming the package is built to be run on the
-_same_ architectures, `configure' can figure that out, but if it prints
-a message saying it cannot guess the machine type, give it the
-`--build=TYPE' option.  TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name which has the form:
-
-     CPU-COMPANY-SYSTEM
-
-where SYSTEM can have one of these forms:
-
-     OS
-     KERNEL-OS
-
-   See the file `config.sub' for the possible values of each field.  If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the machine type.
-
-   If you are _building_ compiler tools for cross-compiling, you should
-use the option `--target=TYPE' to select the type of system they will
-produce code for.
-
-   If you want to _use_ a cross compiler, that generates code for a
-platform different from the build platform, you should specify the
-"host" platform (i.e., that on which the generated programs will
-eventually be run) with `--host=TYPE'.
-
-Sharing Defaults
-================
-
-   If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists.  Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Defining Variables
-==================
-
-   Variables not defined in a site shell script can be set in the
-environment passed to `configure'.  However, some packages may run
-configure again during the build, and the customized values of these
-variables may be lost.  In order to avoid this problem, you should set
-them in the `configure' command line, using `VAR=value'.  For example:
-
-     ./configure CC=/usr/local2/bin/gcc
-
-causes the specified `gcc' to be used as the C compiler (unless it is
-overridden in the site shell script).
-
-Unfortunately, this technique does not work for `CONFIG_SHELL' due to
-an Autoconf bug.  Until the bug is fixed you can use this workaround:
-
-     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-`configure' Invocation
-======================
-
-   `configure' recognizes the following options to control how it
-operates.
-
-`--help'
-`-h'
-     Print a summary of all of the options to `configure', and exit.
-
-`--help=short'
-`--help=recursive'
-     Print a summary of the options unique to this package's
-     `configure', and exit.  The `short' variant lists options used
-     only in the top level, while the `recursive' variant lists options
-     also present in any nested packages.
-
-`--version'
-`-V'
-     Print the version of Autoconf used to generate the `configure'
-     script, and exit.
-
-`--cache-file=FILE'
-     Enable the cache: use and save the results of the tests in FILE,
-     traditionally `config.cache'.  FILE defaults to `/dev/null' to

-
-`--srcdir=DIR'
-     Look for the package's source code in directory DIR.  Usually
-     `configure' can determine that directory automatically.
-
-`--prefix=DIR'
-     Use DIR as the installation prefix.  *note Installation Names::

-
-`--no-create'
-`-n'
-     Run the configure checks, but stop before creating any output

-
-`configure' also accepts some other, not widely useful, options.  Run
-`configure --help' for more details.

-
-SUMMARY OF HOW TO BUILD
-=======================
-
-  Unix:      ./configure; make
-  Windows:   nmake /f Makefile.msc
-
-BUILDING ON POSIX
-=================
-
-The generic installation instructions for autoconf/automake are found
-in the INSTALL file.
-
-The following SQLite specific boolean options are supported:
-
-  --enable-readline           use readline in shell tool   [default=yes]
-  --enable-threadsafe         build a thread-safe library  [default=yes]
-  --enable-dynamic-extensions support loadable extensions  [default=yes]
-
-The default value for the CFLAGS variable (options passed to the C
-compiler) includes debugging symbols in the build, resulting in larger
-binaries than are necessary. Override it on the configure command
-line like this:
-
-  $ CFLAGS="-Os" ./configure
-
-to produce a smaller installation footprint.
-
-Other SQLite compilation parameters can also be set using CFLAGS. For
-example:
-
-  $ CFLAGS="-Os -DSQLITE_THREADSAFE=0" ./configure
-
-
-BUILDING WITH MICROSOFT VISUAL C++
-==================================
-
-To compile for Windows using Microsoft Visual C++:
-
-  $ nmake /f Makefile.msc
-
-Using Microsoft Visual C++ 2005 (or later) is recommended.  Several Windows
-platform variants may be built by adding additional macros to the NMAKE
-command line.
-
-Building for WinRT 8.0
-----------------------
-
-  FOR_WINRT=1
-
-Using Microsoft Visual C++ 2012 (or later) is required.  When using the
-above, something like the following macro will need to be added to the
-NMAKE command line as well:
-
-  "NSDKLIBPATH=%WindowsSdkDir%\..\8.0\lib\win8\um\x86"
-
-Building for WinRT 8.1
-----------------------
-
-  FOR_WINRT=1
-
-Using Microsoft Visual C++ 2013 (or later) is required.  When using the
-above, something like the following macro will need to be added to the
-NMAKE command line as well:
-
-  "NSDKLIBPATH=%WindowsSdkDir%\..\8.1\lib\winv6.3\um\x86"
-
-Building for UWP 10.0
----------------------
-
-  FOR_WINRT=1 FOR_UWP=1
-
-Using Microsoft Visual C++ 2015 (or later) is required.  When using the
-above, something like the following macros will need to be added to the
-NMAKE command line as well:
-
-  "NSDKLIBPATH=%WindowsSdkDir%\..\10\lib\10.0.10586.0\um\x86"
-  "PSDKLIBPATH=%WindowsSdkDir%\..\10\lib\10.0.10586.0\um\x86"
-  "NUCRTLIBPATH=%UniversalCRTSdkDir%\..\10\lib\10.0.10586.0\ucrt\x86"
-
-Building for the Windows 10 SDK
--------------------------------
-
-  FOR_WIN10=1
-
-Using Microsoft Visual C++ 2015 (or later) is required.  When using the
-above, no other macros should be needed on the NMAKE command line.
-
-Other preprocessor defines
---------------------------
-
-Additionally, preprocessor defines may be specified by using the OPTS macro
-on the NMAKE command line.  However, not all possible preprocessor defines
-may be specified in this manner as some require the amalgamation to be built
-with them enabled (see http://www.sqlite.org/compile.html). For example, the
-following will work:
-
-  "OPTS=-DSQLITE_ENABLE_STAT4=1 -DSQLITE_ENABLE_JSON1=1"
-
-However, the following will not compile unless the amalgamation was built
-with it enabled:
-
-  "OPTS=-DSQLITE_ENABLE_UPDATE_DELETE_LIMIT=1"

-This is the SQLite extension for Tcl using the Tcl Extension
-Architecture (TEA).  For additional information on SQLite see
-
-        http://www.sqlite.org/
-
-
-UNIX BUILD
-==========
-
-Building under most UNIX systems is easy, just run the configure script
-and then run make. For more information about the build process, see
-the tcl/unix/README file in the Tcl src dist. The following minimal
-example will install the extension in the /opt/tcl directory.
-
-	$ cd sqlite-*-tea
-	$ ./configure --prefix=/opt/tcl
-	$ make
-	$ make install
-
-WINDOWS BUILD
-=============
-
-The recommended method to build extensions under windows is to use the
-Msys + Mingw build process. This provides a Unix-style build while
-generating native Windows binaries. Using the Msys + Mingw build tools
-means that you can use the same configure script as per the Unix build
-to create a Makefile. See the tcl/win/README file for the URL of
-the Msys + Mingw download.
-
-If you have VC++ then you may wish to use the files in the win
-subdirectory and build the extension using just VC++. These files have
-been designed to be as generic as possible but will require some
-additional maintenance by the project developer to synchronise with
-the TEA configure.in and Makefile.in files. Instructions for using the
-VC++ makefile are written in the first part of the Makefile.vc
-file.

-#                       into a shared library.
-#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
-#                       creating shared libraries.  This symbol typically
-#                       goes at the end of the "ld" commands that build
-#                       shared libraries. The value of the symbol defaults to
-#                       "${LIBS}" if all of the dependent libraries should
-#                       be specified when creating a shared library.  If
-#                       dependent libraries should not be specified (as on
-#                       SunOS 4.x, where they cause the link to fail, or in
-#                       general if Tcl and Tk aren't themselves shared
-#                       libraries), then this symbol has an empty string
-#                       as its value.
-#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
-#                       extensions.  An empty string means we don't know how
-#                       to use shared libraries on this platform.
-#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
-#                       in a static or shared library name, using the $PACKAGE_VERSION variable
-#                       to put the version in the right place.  This is used
-#                       by platforms that need non-standard library names.
-#                       Examples:  ${PACKAGE_VERSION}.so.1.1 on NetBSD, since it needs
-#                       to have a version after the .so, and ${PACKAGE_VERSION}.a
-#                       on AIX, since a shared library needs to have
-#                       a .a extension whereas shared objects for loadable
-#                       extensions have a .so extension.  Defaults to
-#                       ${PACKAGE_VERSION}${SHLIB_SUFFIX}.

-
-#------------------------------------------------------------------------------
-# HOW TO USE this makefile:
-#
-# 1)  It is now necessary to have %MSVCDir% set in the environment.  This is
-#     used  as a check to see if vcvars32.bat had been run prior to running
-#     nmake or during the installation of Microsoft Visual C++, MSVCDir had
-#     been set globally and the PATH adjusted.  Either way is valid.
-#
-#     You'll need to run vcvars32.bat contained in the MsDev's vc(98)/bin
-#     directory to setup the proper environment, if needed, for your current
-#     setup.  This is a needed bootstrap requirement and allows the swapping of
-#     different environments to be easier.
-#
-# 2)  To use the Platform SDK (not expressly needed), run setenv.bat after
-#     vcvars32.bat according to the instructions for it.  This can also turn on
-#     the 64-bit compiler, if your SDK has it.
-#
-# 3)  Targets are:
-#	all       -- Builds everything.
-#       <project> -- Builds the project (eg: nmake sample)
-#	test      -- Builds and runs the test suite.
-#	install   -- Installs the built binaries and libraries to $(INSTALLDIR)
-#		     in an appropriate subdirectory.
-#	clean/realclean/distclean -- varying levels of cleaning.
-#
-# 4)  Macros usable on the commandline:
-#	INSTALLDIR=<path>
-#		Sets where to install Tcl from the built binaries.
-#		C:\Progra~1\Tcl is assumed when not specified.
-#
-#	OPTS=static,msvcrt,staticpkg,threads,symbols,profile,loimpact,none
-#		Sets special options for the core.  The default is for none.
-#		Any combination of the above may be used (comma separated).
-#		'none' will over-ride everything to nothing.
-#
-#		static  =  Builds a static library of the core instead of a
-#			   dll.  The shell will be static (and large), as well.
-#		msvcrt  =  Effects the static option only to switch it from
-#			   using libcmt(d) as the C runtime [by default] to
-#			   msvcrt(d). This is useful for static embedding
-#			   support.
-#		staticpkg = Effects the static option only to switch
-#			   tclshXX.exe to have the dde and reg extension linked
-#			   inside it.
-#		threads =  Turns on full multithreading support.
-#		thrdalloc = Use the thread allocator (shared global free pool).
-#		symbols =  Adds symbols for step debugging.
-#		profile =  Adds profiling hooks.  Map file is assumed.
-#		loimpact =  Adds a flag for how NT treats the heap to keep memory
-#			   in use, low.  This is said to impact alloc performance.
-#
-#	STATS=memdbg,compdbg,none
-#		Sets optional memory and bytecode compiler debugging code added
-#		to the core.  The default is for none.  Any combination of the
-#		above may be used (comma separated).  'none' will over-ride
-#		everything to nothing.
-#
-#		memdbg   = Enables the debugging memory allocator.
-#		compdbg  = Enables byte compilation logging.
-#
-#	MACHINE=(IX86|IA64|ALPHA)
-#		Set the machine type used for the compiler, linker, and
-#		resource compiler.  This hook is needed to tell the tools
-#		when alternate platforms are requested.  IX86 is the default
-#		when not specified.
-#
-#	TMP_DIR=<path>
-#	OUT_DIR=<path>
-#		Hooks to allow the intermediate and output directories to be
-#		changed.  $(OUT_DIR) is assumed to be 
-#		$(BINROOT)\(Release|Debug) based on if symbols are requested.
-#		$(TMP_DIR) will de $(OUT_DIR)\<buildtype> by default.
-#
-#	TESTPAT=<file>
-#		Reads the tests requested to be run from this file.
-#
-#	CFG_ENCODING=encoding
-#		name of encoding for configuration information. Defaults
-#		to cp1252

-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:

-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:

-<title>The Lemon Parser Generator</title>
-</head>
-<body bgcolor='white'>
-<h1 align='center'>The Lemon Parser Generator</h1>
-
-<p>Lemon is an LALR(1) parser generator for C.
-It does the same job as "bison" and "yacc".
-But Lemon is not a bison or yacc clone.  Lemon
-uses a different grammar syntax which is designed to
-reduce the number of coding errors.  Lemon also uses a
-parsing engine that is faster than yacc and
-bison and which is both reentrant and threadsafe.
-(Update: Since the previous sentence was written, bison
-has also been updated so that it too can generate a
-reentrant and threadsafe parser.)
-Lemon also implements features that can be used
-to eliminate resource leaks, making it suitable for use
-in long-running programs such as graphical user interfaces
-or embedded controllers.</p>
-
-<p>This document is an introduction to the Lemon
-parser generator.</p>
-
-<h2>Security Note</h2>
-
-<p>The language parser code created by Lemon is very robust and
-is well-suited for use in internet-facing applications that need to
-safely process maliciously crafted inputs.
-
-<p>The "lemon.exe" command-line tool itself works great when given a valid
-input grammar file and almost always gives helpful
-error messages for malformed inputs.  However,  it is possible for
-a malicious user to craft a grammar file that will cause 
-lemon.exe to crash.
-We do not see this as a problem, as lemon.exe is not intended to be used
-with hostile inputs.
-To summarize:</p>
-
-<ul>
-<li>Parser code generated by lemon &rarr; Robust and secure
-<li>The "lemon.exe" command line tool itself &rarr; Not so much
-</ul>
-
-<h2>Theory of Operation</h2>
-
-<p>The main goal of Lemon is to translate a context free grammar (CFG)
-for a particular language into C code that implements a parser for
-that language.
-The program has two inputs:
-<ul>
-<li>The grammar specification.
-<li>A parser template file.
-</ul>
-Typically, only the grammar specification is supplied by the programmer.
-Lemon comes with a default parser template which works fine for most
-applications.  But the user is free to substitute a different parser
-template if desired.</p>
-
-<p>Depending on command-line options, Lemon will generate up to
-three output files.
-<ul>
-<li>C code to implement the parser.
-<li>A header file defining an integer ID for each terminal symbol.
-<li>An information file that describes the states of the generated parser
-    automaton.
-</ul>
-By default, all three of these output files are generated.
-The header file is suppressed if the "-m" command-line option is
-used and the report file is omitted when "-q" is selected.</p>
-
-<p>The grammar specification file uses a ".y" suffix, by convention.
-In the examples used in this document, we'll assume the name of the
-grammar file is "gram.y".  A typical use of Lemon would be the
-following command:
-<pre>
-   lemon gram.y
-</pre>
-This command will generate three output files named "gram.c",
-"gram.h" and "gram.out".
-The first is C code to implement the parser.  The second
-is the header file that defines numerical values for all
-terminal symbols, and the last is the report that explains
-the states used by the parser automaton.</p>
-
-<h3>Command Line Options</h3>
-
-<p>The behavior of Lemon can be modified using command-line options.
-You can obtain a list of the available command-line options together
-with a brief explanation of what each does by typing
-<pre>
-   lemon "-?"
-</pre>
-As of this writing, the following command-line options are supported:
-<ul>
-<li><b>-b</b>
-Show only the basis for each parser state in the report file.
-<li><b>-c</b>
-Do not compress the generated action tables.  The parser will be a
-little larger and slower, but it will detect syntax errors sooner.
-<li><b>-d</b><i>directory</i>
-Write all output files into <i>directory</i>.  Normally, output files
-are written into the directory that contains the input grammar file.
-<li><b>-D<i>name</i></b>
-Define C preprocessor macro <i>name</i>.  This macro is usable by
-"<tt><a href='#pifdef'>%ifdef</a></tt>" and
-"<tt><a href='#pifdef'>%ifndef</a></tt>" lines
-in the grammar file.
-<li><b>-g</b>
-Do not generate a parser.  Instead write the input grammar to standard
-output with all comments, actions, and other extraneous text removed.
-<li><b>-l</b>
-Omit "#line" directives in the generated parser C code.
-<li><b>-m</b>
-Cause the output C source code to be compatible with the "makeheaders"
-program.
-<li><b>-p</b>
-Display all conflicts that are resolved by
-<a href='#precrules'>precedence rules</a>.
-<li><b>-q</b>
-Suppress generation of the report file.
-<li><b>-r</b>
-Do not sort or renumber the parser states as part of optimization.
-<li><b>-s</b>
-Show parser statistics before existing.
-<li><b>-T<i>file</i></b>
-Use <i>file</i> as the template for the generated C-code parser implementation.
-<li><b>-x</b>
-Print the Lemon version number.
-</ul>
-
-<h3>The Parser Interface</h3>
-
-<p>Lemon doesn't generate a complete, working program.  It only generates
-a few subroutines that implement a parser.  This section describes
-the interface to those subroutines.  It is up to the programmer to
-call these subroutines in an appropriate way in order to produce a
-complete system.</p>
-
-<p>Before a program begins using a Lemon-generated parser, the program
-must first create the parser.
-A new parser is created as follows:
-<pre>
-   void *pParser = ParseAlloc( malloc );
-</pre>
-The ParseAlloc() routine allocates and initializes a new parser and
-returns a pointer to it.
-The actual data structure used to represent a parser is opaque &mdash;
-its internal structure is not visible or usable by the calling routine.
-For this reason, the ParseAlloc() routine returns a pointer to void
-rather than a pointer to some particular structure.
-The sole argument to the ParseAlloc() routine is a pointer to the
-subroutine used to allocate memory.  Typically this means malloc().</p>
-
-<p>After a program is finished using a parser, it can reclaim all
-memory allocated by that parser by calling
-<pre>
-   ParseFree(pParser, free);
-</pre>
-The first argument is the same pointer returned by ParseAlloc().  The
-second argument is a pointer to the function used to release bulk
-memory back to the system.</p>
-
-<p>After a parser has been allocated using ParseAlloc(), the programmer
-must supply the parser with a sequence of tokens (terminal symbols) to
-be parsed.  This is accomplished by calling the following function
-once for each token:
-<pre>
-   Parse(pParser, hTokenID, sTokenData, pArg);
-</pre>
-The first argument to the Parse() routine is the pointer returned by
-ParseAlloc().
-The second argument is a small positive integer that tells the parser the
-type of the next token in the data stream.
-There is one token type for each terminal symbol in the grammar.
-The gram.h file generated by Lemon contains #define statements that
-map symbolic terminal symbol names into appropriate integer values.
-A value of 0 for the second argument is a special flag to the
-parser to indicate that the end of input has been reached.
-The third argument is the value of the given token.  By default,
-the type of the third argument is "void*", but the grammar will
-usually redefine this type to be some kind of structure.
-Typically the second argument will be a broad category of tokens
-such as "identifier" or "number" and the third argument will
-be the name of the identifier or the value of the number.</p>
-
-<p>The Parse() function may have either three or four arguments,
-depending on the grammar.  If the grammar specification file requests
-it (via the <tt><a href='#extraarg'>%extra_argument</a></tt> directive),
-the Parse() function will have a fourth parameter that can be
-of any type chosen by the programmer.  The parser doesn't do anything
-with this argument except to pass it through to action routines.
-This is a convenient mechanism for passing state information down
-to the action routines without having to use global variables.</p>
-
-<p>A typical use of a Lemon parser might look something like the
-following:
-<pre>
-    1 ParseTree *ParseFile(const char *zFilename){
-    2    Tokenizer *pTokenizer;
-    3    void *pParser;
-    4    Token sToken;
-    5    int hTokenId;
-    6    ParserState sState;
-    7
-    8    pTokenizer = TokenizerCreate(zFilename);
-    9    pParser = ParseAlloc( malloc );
-   10    InitParserState(&amp;sState);
-   11    while( GetNextToken(pTokenizer, &amp;hTokenId, &amp;sToken) ){
-   12       Parse(pParser, hTokenId, sToken, &amp;sState);
-   13    }
-   14    Parse(pParser, 0, sToken, &amp;sState);
-   15    ParseFree(pParser, free );
-   16    TokenizerFree(pTokenizer);
-   17    return sState.treeRoot;
-   18 }
-</pre>
-This example shows a user-written routine that parses a file of
-text and returns a pointer to the parse tree.
-(All error-handling code is omitted from this example to keep it
-simple.)
-We assume the existence of some kind of tokenizer which is created
-using TokenizerCreate() on line 8 and deleted by TokenizerFree()
-on line 16.  The GetNextToken() function on line 11 retrieves the
-next token from the input file and puts its type in the
-integer variable hTokenId.  The sToken variable is assumed to be
-some kind of structure that contains details about each token,
-such as its complete text, what line it occurs on, etc.</p>
-
-<p>This example also assumes the existence of structure of type
-ParserState that holds state information about a particular parse.
-An instance of such a structure is created on line 6 and initialized
-on line 10.  A pointer to this structure is passed into the Parse()
-routine as the optional 4th argument.
-The action routine specified by the grammar for the parser can use
-the ParserState structure to hold whatever information is useful and
-appropriate.  In the example, we note that the treeRoot field of
-the ParserState structure is left pointing to the root of the parse
-tree.</p>
-
-<p>The core of this example as it relates to Lemon is as follows:
-<pre>
-   ParseFile(){
-      pParser = ParseAlloc( malloc );
-      while( GetNextToken(pTokenizer,&amp;hTokenId, &amp;sToken) ){
-         Parse(pParser, hTokenId, sToken);
-      }
-      Parse(pParser, 0, sToken);
-      ParseFree(pParser, free );
-   }
-</pre>
-Basically, what a program has to do to use a Lemon-generated parser
-is first create the parser, then send it lots of tokens obtained by
-tokenizing an input source.  When the end of input is reached, the
-Parse() routine should be called one last time with a token type
-of 0.  This step is necessary to inform the parser that the end of
-input has been reached.  Finally, we reclaim memory used by the
-parser by calling ParseFree().</p>
-
-<p>There is one other interface routine that should be mentioned
-before we move on.
-The ParseTrace() function can be used to generate debugging output
-from the parser.  A prototype for this routine is as follows:
-<pre>
-   ParseTrace(FILE *stream, char *zPrefix);
-</pre>
-After this routine is called, a short (one-line) message is written
-to the designated output stream every time the parser changes states
-or calls an action routine.  Each such message is prefaced using
-the text given by zPrefix.  This debugging output can be turned off
-by calling ParseTrace() again with a first argument of NULL (0).</p>
-
-<h3>Differences With YACC and BISON</h3>
-
-<p>Programmers who have previously used the yacc or bison parser
-generator will notice several important differences between yacc and/or
-bison and Lemon.
-<ul>
-<li>In yacc and bison, the parser calls the tokenizer.  In Lemon,
-    the tokenizer calls the parser.
-<li>Lemon uses no global variables.  Yacc and bison use global variables
-    to pass information between the tokenizer and parser.
-<li>Lemon allows multiple parsers to be running simultaneously.  Yacc
-    and bison do not.
-</ul>
-These differences may cause some initial confusion for programmers
-with prior yacc and bison experience.
-But after years of experience using Lemon, I firmly
-believe that the Lemon way of doing things is better.</p>
-
-<p><i>Updated as of 2016-02-16:</i>
-The text above was written in the 1990s.
-We are told that Bison has lately been enhanced to support the
-tokenizer-calls-parser paradigm used by Lemon, and to obviate the
-need for global variables.</p>
-
-<h2>Input File Syntax</h2>
-
-<p>The main purpose of the grammar specification file for Lemon is
-to define the grammar for the parser.  But the input file also
-specifies additional information Lemon requires to do its job.
-Most of the work in using Lemon is in writing an appropriate
-grammar file.</p>
-
-<p>The grammar file for Lemon is, for the most part, free format.
-It does not have sections or divisions like yacc or bison.  Any
-declaration can occur at any point in the file.
-Lemon ignores whitespace (except where it is needed to separate
-tokens), and it honors the same commenting conventions as C and C++.</p>
-
-<h3>Terminals and Nonterminals</h3>
-
-<p>A terminal symbol (token) is any string of alphanumeric
-and/or underscore characters
-that begins with an uppercase letter.
-A terminal can contain lowercase letters after the first character,
-but the usual convention is to make terminals all uppercase.
-A nonterminal, on the other hand, is any string of alphanumeric
-and underscore characters than begins with a lowercase letter.
-Again, the usual convention is to make nonterminals use all lowercase
-letters.</p>
-
-<p>In Lemon, terminal and nonterminal symbols do not need to
-be declared or identified in a separate section of the grammar file.
-Lemon is able to generate a list of all terminals and nonterminals
-by examining the grammar rules, and it can always distinguish a
-terminal from a nonterminal by checking the case of the first
-character of the name.</p>
-
-<p>Yacc and bison allow terminal symbols to have either alphanumeric
-names or to be individual characters included in single quotes, like
-this: ')' or '$'.  Lemon does not allow this alternative form for
-terminal symbols.  With Lemon, all symbols, terminals and nonterminals,
-must have alphanumeric names.</p>
-
-<h3>Grammar Rules</h3>
-
-<p>The main component of a Lemon grammar file is a sequence of grammar
-rules.
-Each grammar rule consists of a nonterminal symbol followed by
-the special symbol "::=" and then a list of terminals and/or nonterminals.
-The rule is terminated by a period.
-The list of terminals and nonterminals on the right-hand side of the
-rule can be empty.
-Rules can occur in any order, except that the left-hand side of the
-first rule is assumed to be the start symbol for the grammar (unless
-specified otherwise using the <tt><a href='#start_symbol'>%start_symbol</a></tt>
-directive described below.)
-A typical sequence of grammar rules might look something like this:
-<pre>
-  expr ::= expr PLUS expr.
-  expr ::= expr TIMES expr.
-  expr ::= LPAREN expr RPAREN.
-  expr ::= VALUE.
-</pre>
-</p>
-
-<p>There is one non-terminal in this example, "expr", and five
-terminal symbols or tokens: "PLUS", "TIMES", "LPAREN",
-"RPAREN" and "VALUE".</p>
-
-<p>Like yacc and bison, Lemon allows the grammar to specify a block
-of C code that will be executed whenever a grammar rule is reduced
-by the parser.
-In Lemon, this action is specified by putting the C code (contained
-within curly braces <tt>{...}</tt>) immediately after the
-period that closes the rule.
-For example:
-<pre>
-  expr ::= expr PLUS expr.   { printf("Doing an addition...\n"); }
-</pre>
-</p>
-
-<p>In order to be useful, grammar actions must normally be linked to
-their associated grammar rules.
-In yacc and bison, this is accomplished by embedding a "$$" in the
-action to stand for the value of the left-hand side of the rule and
-symbols "$1", "$2", and so forth to stand for the value of
-the terminal or nonterminal at position 1, 2 and so forth on the
-right-hand side of the rule.
-This idea is very powerful, but it is also very error-prone.  The
-single most common source of errors in a yacc or bison grammar is
-to miscount the number of symbols on the right-hand side of a grammar
-rule and say "$7" when you really mean "$8".</p>
-
-<p>Lemon avoids the need to count grammar symbols by assigning symbolic
-names to each symbol in a grammar rule and then using those symbolic
-names in the action.
-In yacc or bison, one would write this:
-<pre>
-  expr -&gt; expr PLUS expr  { $$ = $1 + $3; };
-</pre>
-But in Lemon, the same rule becomes the following:
-<pre>
-  expr(A) ::= expr(B) PLUS expr(C).  { A = B+C; }
-</pre>
-In the Lemon rule, any symbol in parentheses after a grammar rule
-symbol becomes a place holder for that symbol in the grammar rule.
-This place holder can then be used in the associated C action to
-stand for the value of that symbol.<p>
-
-<p>The Lemon notation for linking a grammar rule with its reduce
-action is superior to yacc/bison on several counts.
-First, as mentioned above, the Lemon method avoids the need to
-count grammar symbols.
-Secondly, if a terminal or nonterminal in a Lemon grammar rule
-includes a linking symbol in parentheses but that linking symbol
-is not actually used in the reduce action, then an error message
-is generated.
-For example, the rule
-<pre>
-  expr(A) ::= expr(B) PLUS expr(C).  { A = B; }
-</pre>
-will generate an error because the linking symbol "C" is used
-in the grammar rule but not in the reduce action.</p>
-
-<p>The Lemon notation for linking grammar rules to reduce actions
-also facilitates the use of destructors for reclaiming memory
-allocated by the values of terminals and nonterminals on the
-right-hand side of a rule.</p>
-
-<a name='precrules'></a>
-<h3>Precedence Rules</h3>
-
-<p>Lemon resolves parsing ambiguities in exactly the same way as
-yacc and bison.  A shift-reduce conflict is resolved in favor
-of the shift, and a reduce-reduce conflict is resolved by reducing
-whichever rule comes first in the grammar file.</p>
-
-<p>Just like in
-yacc and bison, Lemon allows a measure of control
-over the resolution of parsing conflicts using precedence rules.
-A precedence value can be assigned to any terminal symbol
-using the
-<tt><a href='#pleft'>%left</a></tt>,
-<tt><a href='#pright'>%right</a></tt> or
-<tt><a href='#pnonassoc'>%nonassoc</a></tt> directives.  Terminal symbols
-mentioned in earlier directives have a lower precedence than
-terminal symbols mentioned in later directives.  For example:</p>
-
-<p><pre>
-   %left AND.
-   %left OR.
-   %nonassoc EQ NE GT GE LT LE.
-   %left PLUS MINUS.
-   %left TIMES DIVIDE MOD.
-   %right EXP NOT.
-</pre></p>
-
-<p>In the preceding sequence of directives, the AND operator is
-defined to have the lowest precedence.  The OR operator is one
-precedence level higher.  And so forth.  Hence, the grammar would
-attempt to group the ambiguous expression
-<pre>
-     a AND b OR c
-</pre>
-like this
-<pre>
-     a AND (b OR c).
-</pre>
-The associativity (left, right or nonassoc) is used to determine
-the grouping when the precedence is the same.  AND is left-associative
-in our example, so
-<pre>
-     a AND b AND c
-</pre>
-is parsed like this
-<pre>
-     (a AND b) AND c.
-</pre>
-The EXP operator is right-associative, though, so
-<pre>
-     a EXP b EXP c
-</pre>
-is parsed like this
-<pre>
-     a EXP (b EXP c).
-</pre>
-The nonassoc precedence is used for non-associative operators.
-So
-<pre>
-     a EQ b EQ c
-</pre>
-is an error.</p>
-
-<p>The precedence of non-terminals is transferred to rules as follows:
-The precedence of a grammar rule is equal to the precedence of the
-left-most terminal symbol in the rule for which a precedence is
-defined.  This is normally what you want, but in those cases where
-you want to precedence of a grammar rule to be something different,
-you can specify an alternative precedence symbol by putting the
-symbol in square braces after the period at the end of the rule and
-before any C-code.  For example:</p>
-
-<p><pre>
-   expr = MINUS expr.  [NOT]
-</pre></p>
-
-<p>This rule has a precedence equal to that of the NOT symbol, not the
-MINUS symbol as would have been the case by default.</p>
-
-<p>With the knowledge of how precedence is assigned to terminal
-symbols and individual
-grammar rules, we can now explain precisely how parsing conflicts
-are resolved in Lemon.  Shift-reduce conflicts are resolved
-as follows:
-<ul>
-<li> If either the token to be shifted or the rule to be reduced
-     lacks precedence information, then resolve in favor of the
-     shift, but report a parsing conflict.
-<li> If the precedence of the token to be shifted is greater than
-     the precedence of the rule to reduce, then resolve in favor
-     of the shift.  No parsing conflict is reported.
-<li> If the precedence of the token to be shifted is less than the
-     precedence of the rule to reduce, then resolve in favor of the
-     reduce action.  No parsing conflict is reported.
-<li> If the precedences are the same and the shift token is
-     right-associative, then resolve in favor of the shift.
-     No parsing conflict is reported.
-<li> If the precedences are the same and the shift token is
-     left-associative, then resolve in favor of the reduce.
-     No parsing conflict is reported.
-<li> Otherwise, resolve the conflict by doing the shift, and
-     report a parsing conflict.
-</ul>
-Reduce-reduce conflicts are resolved this way:
-<ul>
-<li> If either reduce rule
-     lacks precedence information, then resolve in favor of the
-     rule that appears first in the grammar, and report a parsing
-     conflict.
-<li> If both rules have precedence and the precedence is different,
-     then resolve the dispute in favor of the rule with the highest
-     precedence, and do not report a conflict.
-<li> Otherwise, resolve the conflict by reducing by the rule that
-     appears first in the grammar, and report a parsing conflict.
-</ul>
-
-<h3>Special Directives</h3>
-
-<p>The input grammar to Lemon consists of grammar rules and special
-directives.  We've described all the grammar rules, so now we'll
-talk about the special directives.</p>
-
-<p>Directives in Lemon can occur in any order.  You can put them before
-the grammar rules, or after the grammar rules, or in the midst of the
-grammar rules.  It doesn't matter.  The relative order of
-directives used to assign precedence to terminals is important, but
-other than that, the order of directives in Lemon is arbitrary.</p>
-
-<p>Lemon supports the following special directives:
-<ul>
-<li><tt><a href='#pcode'>%code</a></tt>
-<li><tt><a href='#default_destructor'>%default_destructor</a></tt>
-<li><tt><a href='#default_type'>%default_type</a></tt>
-<li><tt><a href='#destructor'>%destructor</a></tt>
-<li><tt><a href='#pifdef'>%endif</a></tt>
-<li><tt><a href='#extraarg'>%extra_argument</a></tt>
-<li><tt><a href='#pfallback'>%fallback</a></tt>
-<li><tt><a href='#pifdef'>%ifdef</a></tt>
-<li><tt><a href='#pifdef'>%ifndef</a></tt>

-</ul>
-Each of these directives will be described separately in the
-following sections:</p>
-
-<a name='pcode'></a>
-<h4>The <tt>%code</tt> directive</h4>
-
-<p>The <tt>%code</tt> directive is used to specify additional C code that
-is added to the end of the main output file.  This is similar to
-the <tt><a href='#pinclude'>%include</a></tt> directive except that
-<tt>%include</tt> is inserted at the beginning of the main output file.</p>
-
-<p><tt>%code</tt> is typically used to include some action routines or perhaps
-a tokenizer or even the "main()" function
-as part of the output file.</p>
-
-<a name='default_destructor'></a>
-<h4>The <tt>%default_destructor</tt> directive</h4>
-
-<p>The <tt>%default_destructor</tt> directive specifies a destructor to
-use for non-terminals that do not have their own destructor
-specified by a separate <tt>%destructor</tt> directive.  See the documentation
-on the <tt><a name='#destructor'>%destructor</a></tt> directive below for
-additional information.</p>
-
-<p>In some grammars, many different non-terminal symbols have the
-same data type and hence the same destructor.  This directive is
-a convenient way to specify the same destructor for all those
-non-terminals using a single statement.</p>
-
-<a name='default_type'></a>
-<h4>The <tt>%default_type</tt> directive</h4>
-
-<p>The <tt>%default_type</tt> directive specifies the data type of non-terminal
-symbols that do not have their own data type defined using a separate
-<tt><a href='#ptype'>%type</a></tt> directive.</p>
-
-<a name='destructor'></a>
-<h4>The <tt>%destructor</tt> directive</h4>
-
-<p>The <tt>%destructor</tt> directive is used to specify a destructor for
-a non-terminal symbol.
-(See also the <tt><a href='#token_destructor'>%token_destructor</a></tt>
-directive which is used to specify a destructor for terminal symbols.)</p>
-
-<p>A non-terminal's destructor is called to dispose of the
-non-terminal's value whenever the non-terminal is popped from
-the stack.  This includes all of the following circumstances:
-<ul>
-<li> When a rule reduces and the value of a non-terminal on
-     the right-hand side is not linked to C code.
-<li> When the stack is popped during error processing.
-<li> When the ParseFree() function runs.
-</ul>
-The destructor can do whatever it wants with the value of
-the non-terminal, but its design is to deallocate memory
-or other resources held by that non-terminal.</p>
-
-<p>Consider an example:
-<pre>
-   %type nt {void*}
-   %destructor nt { free($$); }
-   nt(A) ::= ID NUM.   { A = malloc( 100 ); }
-</pre>
-This example is a bit contrived, but it serves to illustrate how
-destructors work.  The example shows a non-terminal named
-"nt" that holds values of type "void*".  When the rule for
-an "nt" reduces, it sets the value of the non-terminal to
-space obtained from malloc().  Later, when the nt non-terminal
-is popped from the stack, the destructor will fire and call
-free() on this malloced space, thus avoiding a memory leak.
-(Note that the symbol "$$" in the destructor code is replaced
-by the value of the non-terminal.)</p>
-
-<p>It is important to note that the value of a non-terminal is passed
-to the destructor whenever the non-terminal is removed from the
-stack, unless the non-terminal is used in a C-code action.  If
-the non-terminal is used by C-code, then it is assumed that the
-C-code will take care of destroying it.
-More commonly, the value is used to build some
-larger structure, and we don't want to destroy it, which is why
-the destructor is not called in this circumstance.</p>
-
-<p>Destructors help avoid memory leaks by automatically freeing
-allocated objects when they go out of scope.
-To do the same using yacc or bison is much more difficult.</p>
-
-<a name='extraarg'></a>
-<h4>The <tt>%extra_argument</tt> directive</h4>
-
-The <tt>%extra_argument</tt> directive instructs Lemon to add a 4th parameter
-to the parameter list of the Parse() function it generates.  Lemon
-doesn't do anything itself with this extra argument, but it does
-make the argument available to C-code action routines, destructors,
-and so forth.  For example, if the grammar file contains:</p>
-
-<p><pre>
-    %extra_argument { MyStruct *pAbc }
-</pre></p>
-
-<p>Then the Parse() function generated will have an 4th parameter
-of type "MyStruct*" and all action routines will have access to
-a variable named "pAbc" that is the value of the 4th parameter
-in the most recent call to Parse().</p>
-
-<p>The <tt>%extra_context</tt> directive works the same except that it
-is passed in on the ParseAlloc() or ParseInit() routines instead of
-on Parse().
-
-<a name='extractx'></a>
-<h4>The <tt>%extra_context</tt> directive</h4>
-
-The <tt>%extra_context</tt> directive instructs Lemon to add a 2th parameter
-to the parameter list of the ParseAlloc() and ParseInif() functions.  Lemon
-doesn't do anything itself with these extra argument, but it does
-store the value make it available to C-code action routines, destructors,
-and so forth.  For example, if the grammar file contains:</p>
-
-<p><pre>
-    %extra_context { MyStruct *pAbc }
-</pre></p>
-
-<p>Then the ParseAlloc() and ParseInit() functions will have an 2th parameter
-of type "MyStruct*" and all action routines will have access to
-a variable named "pAbc" that is the value of that 2th parameter.</p>
-
-<p>The <tt>%extra_argument</tt> directive works the same except that it
-is passed in on the Parse() routine instead of on ParseAlloc()/ParseInit().
-
-<a name='pfallback'></a>
-<h4>The <tt>%fallback</tt> directive</h4>
-
-<p>The <tt>%fallback</tt> directive specifies an alternative meaning for one
-or more tokens.  The alternative meaning is tried if the original token
-would have generated a syntax error.</p>
-
-<p>The <tt>%fallback</tt> directive was added to support robust parsing of SQL
-syntax in <a href='https://www.sqlite.org/'>SQLite</a>.
-The SQL language contains a large assortment of keywords, each of which
-appears as a different token to the language parser.  SQL contains so
-many keywords that it can be difficult for programmers to keep up with
-them all.  Programmers will, therefore, sometimes mistakenly use an
-obscure language keyword for an identifier.  The <tt>%fallback</tt> directive
-provides a mechanism to tell the parser:  "If you are unable to parse
-this keyword, try treating it as an identifier instead."</p>
-
-<p>The syntax of <tt>%fallback</tt> is as follows:
-
-<blockquote>
-<tt>%fallback</tt> <i>ID</i> <i>TOKEN...</i> <b>.</b>
-</blockquote></p>
-
-<p>In words, the <tt>%fallback</tt> directive is followed by a list of token
-names terminated by a period.
-The first token name is the fallback token &mdash; the
-token to which all the other tokens fall back to.  The second and subsequent
-arguments are tokens which fall back to the token identified by the first
-argument.</p>
-
-<a name='pifdef'></a>
-<h4>The <tt>%ifdef</tt>, <tt>%ifndef</tt>, and <tt>%endif</tt> directives</h4>
-
-<p>The <tt>%ifdef</tt>, <tt>%ifndef</tt>, and <tt>%endif</tt> directives
-are similar to #ifdef, #ifndef, and #endif in the C-preprocessor,
-just not as general.
-Each of these directives must begin at the left margin.  No whitespace
-is allowed between the "%" and the directive name.</p>
-
-<p>Grammar text in between "<tt>%ifdef MACRO</tt>" and the next nested
-"<tt>%endif</tt>" is
-ignored unless the "-DMACRO" command-line option is used.  Grammar text
-betwen "<tt>%ifndef MACRO</tt>" and the next nested "<tt>%endif</tt>" is
-included except when the "-DMACRO" command-line option is used.</p>
-
-<p>Note that the argument to <tt>%ifdef</tt> and <tt>%ifndef</tt> must
-be a single preprocessor symbol name, not a general expression.
-There is no "<tt>%else</tt>" directive.</p>
-
-
-<a name='pinclude'></a>
-<h4>The <tt>%include</tt> directive</h4>
-
-<p>The <tt>%include</tt> directive specifies C code that is included at the
-top of the generated parser.  You can include any text you want &mdash;
-the Lemon parser generator copies it blindly.  If you have multiple
-<tt>%include</tt> directives in your grammar file, their values are concatenated
-so that all <tt>%include</tt> code ultimately appears near the top of the
-generated parser, in the same order as it appeared in the grammar.</p>
-
-<p>The <tt>%include</tt> directive is very handy for getting some extra #include
-preprocessor statements at the beginning of the generated parser.
-For example:</p>
-
-<p><pre>
-   %include {#include &lt;unistd.h&gt;}
-</pre></p>
-
-<p>This might be needed, for example, if some of the C actions in the
-grammar call functions that are prototyped in unistd.h.</p>
-
-<a name='pleft'></a>
-<h4>The <tt>%left</tt> directive</h4>
-
-The <tt>%left</tt> directive is used (along with the
-<tt><a href='#pright'>%right</a></tt> and
-<tt><a href='#pnonassoc'>%nonassoc</a></tt> directives) to declare
-precedences of terminal symbols.
-Every terminal symbol whose name appears after
-a <tt>%left</tt> directive but before the next period (".") is
-given the same left-associative precedence value.  Subsequent
-<tt>%left</tt> directives have higher precedence.  For example:</p>
-
-<p><pre>
-   %left AND.
-   %left OR.
-   %nonassoc EQ NE GT GE LT LE.
-   %left PLUS MINUS.
-   %left TIMES DIVIDE MOD.
-   %right EXP NOT.
-</pre></p>
-
-<p>Note the period that terminates each <tt>%left</tt>,
-<tt>%right</tt> or <tt>%nonassoc</tt>
-directive.</p>
-
-<p>LALR(1) grammars can get into a situation where they require
-a large amount of stack space if you make heavy use or right-associative
-operators.  For this reason, it is recommended that you use <tt>%left</tt>
-rather than <tt>%right</tt> whenever possible.</p>
-
-<a name='pname'></a>
-<h4>The <tt>%name</tt> directive</h4>
-
-<p>By default, the functions generated by Lemon all begin with the
-five-character string "Parse".  You can change this string to something
-different using the <tt>%name</tt> directive.  For instance:</p>
-
-<p><pre>
-   %name Abcde
-</pre></p>
-
-<p>Putting this directive in the grammar file will cause Lemon to generate
-functions named
-<ul>
-<li> AbcdeAlloc(),
-<li> AbcdeFree(),
-<li> AbcdeTrace(), and
-<li> Abcde().
-</ul>
-The <tt>%name</tt> directive allows you to generate two or more different
-parsers and link them all into the same executable.</p>
-
-<a name='pnonassoc'></a>
-<h4>The <tt>%nonassoc</tt> directive</h4>
-
-<p>This directive is used to assign non-associative precedence to
-one or more terminal symbols.  See the section on
-<a href='#precrules'>precedence rules</a>
-or on the <tt><a href='#pleft'>%left</a></tt> directive
-for additional information.</p>
-
-<a name='parse_accept'></a>
-<h4>The <tt>%parse_accept</tt> directive</h4>
-
-<p>The <tt>%parse_accept</tt> directive specifies a block of C code that is
-executed whenever the parser accepts its input string.  To "accept"
-an input string means that the parser was able to process all tokens
-without error.</p>
-
-<p>For example:</p>
-
-<p><pre>
-   %parse_accept {
-      printf("parsing complete!\n");
-   }
-</pre></p>
-
-<a name='parse_failure'></a>
-<h4>The <tt>%parse_failure</tt> directive</h4>
-
-<p>The <tt>%parse_failure</tt> directive specifies a block of C code that
-is executed whenever the parser fails complete.  This code is not
-executed until the parser has tried and failed to resolve an input
-error using is usual error recovery strategy.  The routine is
-only invoked when parsing is unable to continue.</p>
-
-<p><pre>
-   %parse_failure {
-     fprintf(stderr,"Giving up.  Parser is hopelessly lost...\n");
-   }
-</pre></p>
-
-<a name='pright'></a>
-<h4>The <tt>%right</tt> directive</h4>
-
-<p>This directive is used to assign right-associative precedence to
-one or more terminal symbols.  See the section on
-<a href='#precrules'>precedence rules</a>
-or on the <a href='#pleft'>%left</a> directive for additional information.</p>
-
-<a name='stack_overflow'></a>
-<h4>The <tt>%stack_overflow</tt> directive</h4>
-
-<p>The <tt>%stack_overflow</tt> directive specifies a block of C code that
-is executed if the parser's internal stack ever overflows.  Typically
-this just prints an error message.  After a stack overflow, the parser
-will be unable to continue and must be reset.</p>
-
-<p><pre>
-   %stack_overflow {
-     fprintf(stderr,"Giving up.  Parser stack overflow\n");
-   }
-</pre></p>
-
-<p>You can help prevent parser stack overflows by avoiding the use
-of right recursion and right-precedence operators in your grammar.
-Use left recursion and and left-precedence operators instead to
-encourage rules to reduce sooner and keep the stack size down.
-For example, do rules like this:
-<pre>
-   list ::= list element.      // left-recursion.  Good!
-   list ::= .
-</pre>
-Not like this:
-<pre>
-   list ::= element list.      // right-recursion.  Bad!
-   list ::= .
-</pre></p>
-
-<a name='stack_size'></a>
-<h4>The <tt>%stack_size</tt> directive</h4>
-
-<p>If stack overflow is a problem and you can't resolve the trouble
-by using left-recursion, then you might want to increase the size
-of the parser's stack using this directive.  Put an positive integer
-after the <tt>%stack_size</tt> directive and Lemon will generate a parse
-with a stack of the requested size.  The default value is 100.</p>
-
-<p><pre>
-   %stack_size 2000
-</pre></p>
-
-<a name='start_symbol'></a>
-<h4>The <tt>%start_symbol</tt> directive</h4>
-
-<p>By default, the start symbol for the grammar that Lemon generates
-is the first non-terminal that appears in the grammar file.  But you
-can choose a different start symbol using the
-<tt>%start_symbol</tt> directive.</p>
-
-<p><pre>
-   %start_symbol  prog
-</pre></p>
-
-<a name='syntax_error'></a>
-<h4>The <tt>%syntax_error</tt> directive</h4>
-
-<p>See <a href='#error_processing'>Error Processing</a>.</p>
-
-<a name='token_class'></a>
-<h4>The <tt>%token_class</tt> directive</h4>
-
-<p>Undocumented.  Appears to be related to the MULTITERMINAL concept.
-<a href='http://sqlite.org/src/fdiff?v1=796930d5fc2036c7&v2=624b24c5dc048e09&sbs=0'>Implementation</a>.</p>
-
-<a name='token_destructor'></a>
-<h4>The <tt>%token_destructor</tt> directive</h4>
-
-<p>The <tt>%destructor</tt> directive assigns a destructor to a non-terminal
-symbol.  (See the description of the
-<tt><a href='%destructor'>%destructor</a></tt> directive above.)
-The <tt>%token_destructor</tt> directive does the same thing
-for all terminal symbols.</p>
-
-<p>Unlike non-terminal symbols which may each have a different data type
-for their values, terminals all use the same data type (defined by
-the <tt><a href='#token_type'>%token_type</a></tt> directive)
-and so they use a common destructor.
-Other than that, the token destructor works just like the non-terminal
-destructors.</p>
-
-<a name='token_prefix'></a>
-<h4>The <tt>%token_prefix</tt> directive</h4>
-
-<p>Lemon generates #defines that assign small integer constants
-to each terminal symbol in the grammar.  If desired, Lemon will
-add a prefix specified by this directive
-to each of the #defines it generates.</p>
-
-<p>So if the default output of Lemon looked like this:
-<pre>
-    #define AND              1
-    #define MINUS            2
-    #define OR               3
-    #define PLUS             4
-</pre>
-You can insert a statement into the grammar like this:
-<pre>
-    %token_prefix    TOKEN_
-</pre>
-to cause Lemon to produce these symbols instead:
-<pre>
-    #define TOKEN_AND        1
-    #define TOKEN_MINUS      2
-    #define TOKEN_OR         3
-    #define TOKEN_PLUS       4
-</pre></p>
-
-<a name='token_type'></a><a name='ptype'></a>
-<h4>The <tt>%token_type</tt> and <tt>%type</tt> directives</h4>
-
-<p>These directives are used to specify the data types for values
-on the parser's stack associated with terminal and non-terminal
-symbols.  The values of all terminal symbols must be of the same
-type.  This turns out to be the same data type as the 3rd parameter
-to the Parse() function generated by Lemon.  Typically, you will
-make the value of a terminal symbol by a pointer to some kind of
-token structure.  Like this:</p>
-
-<p><pre>
-   %token_type    {Token*}
-</pre></p>
-
-<p>If the data type of terminals is not specified, the default value
-is "void*".</p>
-
-<p>Non-terminal symbols can each have their own data types.  Typically
-the data type of a non-terminal is a pointer to the root of a parse tree
-structure that contains all information about that non-terminal.
-For example:</p>
-
-<p><pre>
-   %type   expr  {Expr*}
-</pre></p>
-
-<p>Each entry on the parser's stack is actually a union containing
-instances of all data types for every non-terminal and terminal symbol.
-Lemon will automatically use the correct element of this union depending
-on what the corresponding non-terminal or terminal symbol is.  But
-the grammar designer should keep in mind that the size of the union
-will be the size of its largest element.  So if you have a single
-non-terminal whose data type requires 1K of storage, then your 100
-entry parser stack will require 100K of heap space.  If you are willing
-and able to pay that price, fine.  You just need to know.</p>
-
-<a name='pwildcard'></a>
-<h4>The <tt>%wildcard</tt> directive</h4>
-
-<p>The <tt>%wildcard</tt> directive is followed by a single token name and a
-period.  This directive specifies that the identified token should
-match any input token.</p>
-
-<p>When the generated parser has the choice of matching an input against
-the wildcard token and some other token, the other token is always used.
-The wildcard token is only matched if there are no alternatives.</p>
-
-<a name='error_processing'></a>
-<h3>Error Processing</h3>
-
-<p>After extensive experimentation over several years, it has been
-discovered that the error recovery strategy used by yacc is about
-as good as it gets.  And so that is what Lemon uses.</p>
-
-<p>When a Lemon-generated parser encounters a syntax error, it
-first invokes the code specified by the <tt>%syntax_error</tt> directive, if
-any.  It then enters its error recovery strategy.  The error recovery
-strategy is to begin popping the parsers stack until it enters a
-state where it is permitted to shift a special non-terminal symbol
-named "error".  It then shifts this non-terminal and continues
-parsing.  The <tt>%syntax_error</tt> routine will not be called again
-until at least three new tokens have been successfully shifted.</p>
-
-<p>If the parser pops its stack until the stack is empty, and it still
-is unable to shift the error symbol, then the
-<tt><a href='#parse_failure'>%parse_failure</a></tt> routine
-is invoked and the parser resets itself to its start state, ready
-to begin parsing a new file.  This is what will happen at the very
-first syntax error, of course, if there are no instances of the
-"error" non-terminal in your grammar.</p>

-there is an extra RECOVER state used for wal-index reconstruction.
-
-The meanings of the various wal-index locking states is as follows:
-
-   UNLOCKED    - The wal-index is not in use.
-
-   READ        - Some prefix of the wal-index is being read. Additional
-                 wal-index information can be appended at any time.  The
-                 newly appended content will be ignored by the holder of
-                 the READ lock.
-
-   READ_FULL   - The entire wal-index is being read.  No new information
-                 can be added to the wal-index.  The holder of a READ_FULL
-                 lock promises never to read pages from the database file
-                 that are available anywhere in the wal-index.
-
-   WRITE       - It is OK to append to the wal-index file and to adjust
-                 the header to indicate the new "last valid frame".
-
-   PENDING     - Waiting on all READ locks to clear so that a
-                 CHECKPOINT lock can be acquired.
-
-   CHECKPOINT  - It is OK to write any WAL data into the database file
-                 and zero the last valid frame field of the wal-index
-                 header.  The wal-index file itself may not be changed
-                 other than to zero the last valid frame field in the
-                 header.
-
-   RECOVER     - Held during wal-index recovery.  Used to prevent a
-                 race if multiple clients try to recover a wal-index at
-                 the same time.
-   
-
-A particular lock manager implementation may coalesce one or more of 
-the wal-index locking states, though with a reduction in concurrency.
-For example, an implemention might implement only exclusive locking,
-in which case all states would be equivalent to CHECKPOINT, meaning that 
-only one reader or one writer or one checkpointer could be active at a 
-time.  Or, an implementation might combine READ and READ_FULL into 
-a single state equivalent to READ, meaning that a writer could
-coexist with a reader, but no reader or writers could coexist with a
-checkpointer.
-
-The lock manager must obey the following rules:
-
-(1)  A READ cannot coexist with CHECKPOINT.
-(2)  A READ_FULL cannot coexist with WRITE.
-(3)  None of WRITE, PENDING, CHECKPOINT, or RECOVER can coexist.
-
-The SQLite core will obey the next set of rules.  These rules are
-assertions on the behavior of the SQLite core which might be verified
-during testing using an instrumented lock manager.
-
-(5)  No part of the wal-index will be read without holding either some
-     kind of SHM lock or an EXCLUSIVE lock on the original database.
-     The original database is the file named in the 2nd parameter to
-     the xShmOpen method.
-
-(6)  A holder of a READ_FULL will never read any page of the database
-     file that is contained anywhere in the wal-index.
-
-(7)  No part of the wal-index other than the header will be written nor
-     will the size of the wal-index grow without holding a WRITE or
-     an EXCLUSIVE on the original database file.
-
-(8)  The wal-index header will not be written without holding one of
-     WRITE, CHECKPOINT, or RECOVER on the wal-index or an EXCLUSIVE on
-     the original database files.
-
-(9)  A CHECKPOINT or RECOVER must be held on the wal-index, or an
-     EXCLUSIVE on the original database file, in order to reset the 
-     last valid frame counter in the header of the wal-index back to zero.
-
-(10) A WRITE can only increase the last valid frame pointer in the header.
-
-The SQLite core will only ever send requests for UNLOCK, READ, WRITE,
-CHECKPOINT, or RECOVER to the lock manager.   The SQLite core will never
-request a READ_FULL or PENDING lock though the lock manager may deliver
-those locking states in response to READ and CHECKPOINT requests,
-respectively, if and only if the requested READ or CHECKPOINT cannot
-be delivered.
-
-The following are the allowed lock transitions:
-
-       Original-State     Request         New-State
-       --------------     ----------      ----------
-(11a)  UNLOCK             READ            READ
-(11b)  UNLOCK             READ            READ_FULL
-(11c)  UNLOCK             CHECKPOINT      PENDING
-(11d)  UNLOCK             CHECKPOINT      CHECKPOINT
-(11e)  READ               UNLOCK          UNLOCK
-(11f)  READ               WRITE           WRITE
-(11g)  READ               RECOVER         RECOVER
-(11h)  READ_FULL          UNLOCK          UNLOCK
-(11i)  READ_FULL          WRITE           WRITE
-(11j)  READ_FULL          RECOVER         RECOVER
-(11k)  WRITE              READ            READ
-(11l)  PENDING            UNLOCK          UNLOCK
-(11m)  PENDING            CHECKPOINT      CHECKPOINT
-(11n)  CHECKPOINT         UNLOCK          UNLOCK
-(11o)  RECOVER            READ            READ
-
-These 15 transitions are all that needs to be supported.  The lock
-manager implementation can assert that fact.  The other 27 possible
-transitions among the 7 locking states will never occur.

-NOTE (2012-11-29):
-
-The functionality implemented by this extension has been superseded
-by WAL-mode.  This module is no longer supported or maintained.  The
-code is retained for historical reference only.
-
-------------------------------------------------------------------------------
-
-Normally, when SQLite writes to a database file, it waits until the write
-operation is finished before returning control to the calling application.
-Since writing to the file-system is usually very slow compared with CPU
-bound operations, this can be a performance bottleneck. This directory
-contains an extension that causes SQLite to perform all write requests
-using a separate thread running in the background. Although this does not
-reduce the overall system resources (CPU, disk bandwidth etc.) at all, it
-allows SQLite to return control to the caller quickly even when writing to
-the database, eliminating the bottleneck.

-    1.2 Limitations
-    1.3 Locking and Concurrency
-
-  2. Compilation and Usage
-
-  3. Porting
-
-
-
-1. FUNCTIONALITY
-
-  With asynchronous I/O, write requests are handled by a separate thread
-  running in the background.  This means that the thread that initiates
-  a database write does not have to wait for (sometimes slow) disk I/O
-  to occur.  The write seems to happen very quickly, though in reality
-  it is happening at its usual slow pace in the background.
-
-  Asynchronous I/O appears to give better responsiveness, but at a price.
-  You lose the Durable property.  With the default I/O backend of SQLite,
-  once a write completes, you know that the information you wrote is
-  safely on disk.  With the asynchronous I/O, this is not the case.  If
-  your program crashes or if a power loss occurs after the database
-  write but before the asynchronous write thread has completed, then the
-  database change might never make it to disk and the next user of the
-  database might not see your change.
-
-  You lose Durability with asynchronous I/O, but you still retain the
-  other parts of ACID:  Atomic,  Consistent, and Isolated.  Many
-  appliations get along fine without the Durablity.
-
-  1.1 How it Works
-
-    Asynchronous I/O works by creating a special SQLite "vfs" structure
-    and registering it with sqlite3_vfs_register(). When files opened via 
-    this vfs are written to (using the vfs xWrite() method), the data is not 
-    written directly to disk, but is placed in the "write-queue" to be
-    handled by the background thread.
-
-    When files opened with the asynchronous vfs are read from 
-    (using the vfs xRead() method), the data is read from the file on 
-    disk and the write-queue, so that from the point of view of
-    the vfs reader the xWrite() appears to have already completed.
-
-    The special vfs is registered (and unregistered) by calls to the 
-    API functions sqlite3async_initialize() and sqlite3async_shutdown().
-    See section "Compilation and Usage" below for details.
-
-  1.2 Limitations
-
-    In order to gain experience with the main ideas surrounding asynchronous 
-    IO, this implementation is deliberately kept simple. Additional 
-    capabilities may be added in the future.
-
-    For example, as currently implemented, if writes are happening at a 
-    steady stream that exceeds the I/O capability of the background writer
-    thread, the queue of pending write operations will grow without bound.
-    If this goes on for long enough, the host system could run out of memory. 
-    A more sophisticated module could to keep track of the quantity of 
-    pending writes and stop accepting new write requests when the queue of 
-    pending writes grows too large.
-
-  1.3 Locking and Concurrency
-
-    Multiple connections from within a single process that use this
-    implementation of asynchronous IO may access a single database
-    file concurrently. From the point of view of the user, if all
-    connections are from within a single process, there is no difference
-    between the concurrency offered by "normal" SQLite and SQLite
-    using the asynchronous backend.
-
-    If file-locking is enabled (it is enabled by default), then connections
-    from multiple processes may also read and write the database file.
-    However concurrency is reduced as follows:
-
-      * When a connection using asynchronous IO begins a database
-        transaction, the database is locked immediately. However the
-        lock is not released until after all relevant operations
-        in the write-queue have been flushed to disk. This means
-        (for example) that the database may remain locked for some 
-        time after a "COMMIT" or "ROLLBACK" is issued.
-
-      * If an application using asynchronous IO executes transactions
-        in quick succession, other database users may be effectively
-        locked out of the database. This is because when a BEGIN
-        is executed, a database lock is established immediately. But
-        when the corresponding COMMIT or ROLLBACK occurs, the lock
-        is not released until the relevant part of the write-queue 
-        has been flushed through. As a result, if a COMMIT is followed
-        by a BEGIN before the write-queue is flushed through, the database 
-        is never unlocked,preventing other processes from accessing 
-        the database.
-
-    File-locking may be disabled at runtime using the sqlite3async_control()
-    API (see below). This may improve performance when an NFS or other 
-    network file-system, as the synchronous round-trips to the server be 
-    required to establish file locks are avoided. However, if multiple 
-    connections attempt to access the same database file when file-locking
-    is disabled, application crashes and database corruption is a likely
-    outcome.
-
-
-2. COMPILATION AND USAGE
-
-  The asynchronous IO extension consists of a single file of C code
-  (sqlite3async.c), and a header file (sqlite3async.h) that defines the 
-  C API used by applications to activate and control the modules 
-  functionality.
-
-  To use the asynchronous IO extension, compile sqlite3async.c as
-  part of the application that uses SQLite. Then use the API defined
-  in sqlite3async.h to initialize and configure the module.
-
-  The asynchronous IO VFS API is described in detail in comments in 
-  sqlite3async.h. Using the API usually consists of the following steps:
-
-    1. Register the asynchronous IO VFS with SQLite by calling the
-       sqlite3async_initialize() function.
-
-    2. Create a background thread to perform write operations and call
-       sqlite3async_run().
-
-    3. Use the normal SQLite API to read and write to databases via 
-       the asynchronous IO VFS.
-
-  Refer to sqlite3async.h for details.
-
-
-3. PORTING
-
-  Currently the asynchronous IO extension is compatible with win32 systems
-  and systems that support the pthreads interface, including Mac OSX, Linux, 
-  and other varieties of Unix. 
-
-  To port the asynchronous IO extension to another platform, the user must
-  implement mutex and condition variable primitives for the new platform.
-  Currently there is no externally available interface to allow this, but
-  modifying the code within sqlite3async.c to include the new platforms
-  concurrency primitives is relatively easy. Search within sqlite3async.c
-  for the comment string "PORTING FUNCTIONS" for details. Then implement
-  new versions of each of the following:
-
-    static void async_mutex_enter(int eMutex);
-    static void async_mutex_leave(int eMutex);
-    static void async_cond_wait(int eCond, int eMutex);
-    static void async_cond_signal(int eCond);
-    static void async_sched_yield(void);
-
-  The functionality required of each of the above functions is described
-  in comments in sqlite3async.c.

-** THREAD SAFETY NOTES
-**
-** Basic rules:
-**
-**     * Both read and write access to the global write-op queue must be 
-**       protected by the async.queueMutex. As are the async.ioError and
-**       async.nFile variables.
-**
-**     * The async.pLock list and all AsyncLock and AsyncFileLock
-**       structures must be protected by the async.lockMutex mutex.
-**
-**     * The file handles from the underlying system are not assumed to 
-**       be thread safe.
-**
-**     * See the last two paragraphs under "The Writer Thread" for
-**       an assumption to do with file-handle synchronization by the Os.
-**
-** Deadlock prevention:
-**
-**     There are three mutex used by the system: the "writer" mutex, 
-**     the "queue" mutex and the "lock" mutex. Rules are:
-**
-**     * It is illegal to block on the writer mutex when any other mutex
-**       are held, and 
-**
-**     * It is illegal to block on the queue mutex when the lock mutex
-**       is held.
-**
-**     i.e. mutex's must be grabbed in the order "writer", "queue", "lock".
-**
-** File system operations (invoked by SQLite thread):
-**
-**     xOpen
-**     xDelete
-**     xFileExists
-**
-** File handle operations (invoked by SQLite thread):
-**
-**         asyncWrite, asyncClose, asyncTruncate, asyncSync 
-**    
-**     The operations above add an entry to the global write-op list. They
-**     prepare the entry, acquire the async.queueMutex momentarily while
-**     list pointers are  manipulated to insert the new entry, then release
-**     the mutex and signal the writer thread to wake up in case it happens
-**     to be asleep.
-**
-**    
-**         asyncRead, asyncFileSize.
-**
-**     Read operations. Both of these read from both the underlying file
-**     first then adjust their result based on pending writes in the 
-**     write-op queue.   So async.queueMutex is held for the duration
-**     of these operations to prevent other threads from changing the
-**     queue in mid operation.
-**    
-**
-**         asyncLock, asyncUnlock, asyncCheckReservedLock
-**    
-**     These primitives implement in-process locking using a hash table
-**     on the file name.  Files are locked correctly for connections coming
-**     from the same process.  But other processes cannot see these locks
-**     and will therefore not honor them.
-**
-**
-** The writer thread:
-**
-**     The async.writerMutex is used to make sure only there is only
-**     a single writer thread running at a time.
-**
-**     Inside the writer thread is a loop that works like this:
-**
-**         WHILE (write-op list is not empty)
-**             Do IO operation at head of write-op list
-**             Remove entry from head of write-op list
-**         END WHILE
-**
-**     The async.queueMutex is always held during the <write-op list is 
-**     not empty> test, and when the entry is removed from the head
-**     of the write-op list. Sometimes it is held for the interim
-**     period (while the IO is performed), and sometimes it is
-**     relinquished. It is relinquished if (a) the IO op is an
-**     ASYNC_CLOSE or (b) when the file handle was opened, two of
-**     the underlying systems handles were opened on the same
-**     file-system entry.
-**
-**     If condition (b) above is true, then one file-handle 
-**     (AsyncFile.pBaseRead) is used exclusively by sqlite threads to read the
-**     file, the other (AsyncFile.pBaseWrite) by sqlite3_async_flush() 
-**     threads to perform write() operations. This means that read 
-**     operations are not blocked by asynchronous writes (although 
-**     asynchronous writes may still be blocked by reads).
-**
-**     This assumes that the OS keeps two handles open on the same file
-**     properly in sync. That is, any read operation that starts after a
-**     write operation on the same file system entry has completed returns
-**     data consistent with the write. We also assume that if one thread 
-**     reads a file while another is writing it all bytes other than the
-**     ones actually being written contain valid data.
-**
-**     If the above assumptions are not true, set the preprocessor symbol
-**     SQLITE_ASYNC_TWO_FILEHANDLES to 0.

-** PORTING FUNCTIONS
-**
-** There are two definitions of the following functions. One for pthreads
-** compatible systems and one for Win32. These functions isolate the OS
-** specific code required by each platform.
-**
-** The system uses three mutexes and a single condition variable. To
-** block on a mutex, async_mutex_enter() is called. The parameter passed
-** to async_mutex_enter(), which must be one of ASYNC_MUTEX_LOCK,
-** ASYNC_MUTEX_QUEUE or ASYNC_MUTEX_WRITER, identifies which of the three
-** mutexes to lock. Similarly, to unlock a mutex, async_mutex_leave() is
-** called with a parameter identifying the mutex being unlocked. Mutexes
-** are not recursive - it is an error to call async_mutex_enter() to
-** lock a mutex that is already locked, or to call async_mutex_leave()
-** to unlock a mutex that is not currently locked.
-**
-** The async_cond_wait() and async_cond_signal() functions are modelled
-** on the pthreads functions with similar names. The first parameter to
-** both functions is always ASYNC_COND_QUEUE. When async_cond_wait()
-** is called the mutex identified by the second parameter must be held.
-** The mutex is unlocked, and the calling thread simultaneously begins 
-** waiting for the condition variable to be signalled by another thread.
-** After another thread signals the condition variable, the calling
-** thread stops waiting, locks mutex eMutex and returns. The 
-** async_cond_signal() function is used to signal the condition variable. 
-** It is assumed that the mutex used by the thread calling async_cond_wait() 
-** is held by the caller of async_cond_signal() (otherwise there would be 
-** a race condition).
-**
-** It is guaranteed that no other thread will call async_cond_wait() when
-** there is already a thread waiting on the condition variable.
-**
-** The async_sched_yield() function is called to suggest to the operating
-** system that it would be a good time to shift the current thread off the
-** CPU. The system will still work if this function is not implemented
-** (it is not currently implemented for win32), but it might be marginally

-** This function may only be called when the asynchronous IO VFS is

-** to query or configure various parameters that affect the operation 
-** of the asynchronous IO VFS. At present there are three parameters 
-** supported:
-**
-**   * The "halt" parameter, which configures the circumstances under
-**     which the sqlite3async_run() parameter is configured.
-**
-**   * The "delay" parameter. Setting the delay parameter to a non-zero
-**     value causes the sqlite3async_run() function to sleep for the
-**     configured number of milliseconds between each queued write 
-**     operation.
-**
-**   * The "lockfiles" parameter. This parameter determines whether or 
-**     not the asynchronous IO VFS locks the database files it operates
-**     on. Disabling file locking can improve throughput.
-**
-** This function is always passed two arguments. When setting the value
-** of a parameter, the first argument must be one of SQLITEASYNC_HALT,
-** SQLITEASYNC_DELAY or SQLITEASYNC_LOCKFILES. The second argument must
-** be passed the new value for the parameter as type "int".
-**
-** When querying the current value of a paramter, the first argument must
-** be one of SQLITEASYNC_GET_HALT, GET_DELAY or GET_LOCKFILES. The second 
-** argument to this function must be of type (int *). The current value
-** of the queried parameter is copied to the memory pointed to by the
-** second argument. For example:
-**
-**   int eCurrentHalt;
-**   int eNewHalt = SQLITEASYNC_HALT_IDLE;
-**
-**   sqlite3async_control(SQLITEASYNC_HALT, eNewHalt);
-**   sqlite3async_control(SQLITEASYNC_GET_HALT, &eCurrentHalt);
-**   assert( eNewHalt==eCurrentHalt );
-**
-** See below for more detail on each configuration parameter.
-**
-** SQLITEASYNC_HALT:
-**
-**   This is used to set the value of the "halt" parameter. The second
-**   argument must be one of the SQLITEASYNC_HALT_XXX symbols defined
-**   below (either NEVER, IDLE and NOW).
-**
-**   If the parameter is set to NEVER, then calls to sqlite3async_run()
-**   never return. This is the default setting. If the parameter is set
-**   to IDLE, then calls to sqlite3async_run() return as soon as the
-**   queue of pending write operations is empty. If the parameter is set
-**   to NOW, then calls to sqlite3async_run() return as quickly as 
-**   possible, without processing any pending write requests.
-**
-**   If an attempt is made to set this parameter to an integer value other
-**   than SQLITEASYNC_HALT_NEVER, IDLE or NOW, then sqlite3async_control() 
-**   returns SQLITE_MISUSE and the current value of the parameter is not 
-**   modified.
-**
-**   Modifying the "halt" parameter affects calls to sqlite3async_run() 
-**   made by other threads that are currently in progress.
-**
-** SQLITEASYNC_DELAY:
-**
-**   This is used to set the value of the "delay" parameter. If set to
-**   a non-zero value, then after completing a pending write request, the
-**   sqlite3async_run() function sleeps for the configured number of 
-**   milliseconds.
-**
-**   If an attempt is made to set this parameter to a negative value,
-**   sqlite3async_control() returns SQLITE_MISUSE and the current value
-**   of the parameter is not modified.
-**
-**   Modifying the "delay" parameter affects calls to sqlite3async_run() 
-**   made by other threads that are currently in progress.
-**
-** SQLITEASYNC_LOCKFILES:
-**
-**   This is used to set the value of the "lockfiles" parameter. This
-**   parameter must be set to either 0 or 1. If set to 1, then the
-**   asynchronous IO VFS uses the xLock() and xUnlock() methods of the
-**   parent VFS to lock database files being read and/or written. If
-**   the parameter is set to 0, then these locks are omitted.
-**
-**   This parameter may only be set when there are no open database
-**   connections using the VFS and the queue of pending write requests
-**   is empty. Attempting to set it when this is not true, or to set it 
-**   to a value other than 0 or 1 causes sqlite3async_control() to return
-**   SQLITE_MISUSE and the value of the parameter to remain unchanged.
-**
-**   If this parameter is set to zero, then it is only safe to access the
-**   database via the asynchronous IO VFS from within a single process. If
-**   while writing to the database via the asynchronous IO VFS the database
-**   is also read or written from within another process, or via another
-**   connection that does not use the asynchronous IO VFS within the same
-**   process, the results are undefined (and may include crashes or database
-**   corruption).
-**
-**   Alternatively, if this parameter is set to 1, then it is safe to access
-**   the database from multiple connections within multiple processes using
-**   either the asynchronous IO VFS or the parent VFS directly.

-## SQLite Expert Extension
-
-This folder contains code for a simple system to propose useful indexes
-given a database and a set of SQL queries. It works as follows:
-
-  1. The user database schema is copied to a temporary database.
-
-  1. All SQL queries are prepared against the temporary database.
-     Information regarding the WHERE and ORDER BY clauses, and other query
-     features that affect index selection are recorded.
-
-  1. The information gathered in step 2 is used to create candidate 
-     indexes - indexes that the planner might have made use of in the previous
-     step, had they been available.
-
-  1. A subset of the data in the user database is used to generate statistics
-     for all existing indexes and the candidate indexes generated in step 3
-     above.

-  1. The SQL queries are prepared a second time. If the planner uses any
-     of the indexes created in step 3, they are recommended to the user.
-
-# C API
-
-The SQLite expert C API is defined in sqlite3expert.h. Most uses will proceed
-as follows:
-
-  1. An sqlite3expert object is created by calling **sqlite3\_expert\_new()**.
-     A database handle opened by the user is passed as an argument.
-
-  1. The sqlite3expert object is configured with one or more SQL statements
-     by making one or more calls to **sqlite3\_expert\_sql()**. Each call may
-     specify a single SQL statement, or multiple statements separated by
-     semi-colons.
-  
-  1. Optionally, the **sqlite3\_expert\_config()** API may be used to 
-     configure the size of the data subset used to generate index statistics.
-     Using a smaller subset of the data can speed up the analysis.
-
-  1. **sqlite3\_expert\_analyze()** is called to run the analysis.
-
-  1. One or more calls are made to **sqlite3\_expert\_report()** to extract
-     components of the results of the analysis.
-
-  1. **sqlite3\_expert\_destroy()** is called to free all resources.
-
-Refer to comments in sqlite3expert.h for further details.
-
-# sqlite3_expert application
-
-The file "expert.c" contains the code for a command line application that
-uses the API described above. It can be compiled with (for example):
-
-<pre>
-  gcc -O2 sqlite3.c expert.c sqlite3expert.c -o sqlite3_expert
-</pre>
-
-Assuming the database is named "test.db", it can then be run to analyze a
-single query:
-
-<pre>
-  ./sqlite3_expert -sql &lt;sql-query&gt; test.db
-</pre>
-
-Or an entire text file worth of queries with:
-
-<pre>
-  ./sqlite3_expert -file &lt;text-file&gt; test.db
-</pre>
-
-By default, sqlite3\_expert generates index statistics using all the data in
-the user database. For a large database, this may be prohibitively time
-consuming. The "-sample" option may be used to configure sqlite3\_expert to
-generate statistics based on an integer percentage of the user database as
-follows:
-
-<pre>
-  # Generate statistics based on 25% of the user database rows:
-  ./sqlite3_expert -sample 25 -sql &lt;sql-query&gt; test.db
-
-  # Do not generate any statistics at all:
-  ./sqlite3_expert -sample 0 -sql &lt;sql-query&gt; test.db
-</pre>

-** EXPERT_CONFIG_SAMPLE:
-**   By default, sqlite3_expert_analyze() generates sqlite_stat1 data for
-**   each candidate index. This involves scanning and sorting the entire
-**   contents of each user database table once for each candidate index
-**   associated with the table. For large databases, this can be 
-**   prohibitively slow. This option allows the sqlite3expert object to
-**   be configured so that sqlite_stat1 data is instead generated based on a
-**   subset of each table, or so that no sqlite_stat1 data is used at all.
-**
-**   A single integer argument is passed to this option. If the value is less
-**   than or equal to zero, then no sqlite_stat1 data is generated or used by
-**   the analysis - indexes are recommended based on the database schema only.
-**   Or, if the value is 100 or greater, complete sqlite_stat1 data is
-**   generated for each candidate index (this is the default). Finally, if the
-**   value falls between 0 and 100, then it represents the percentage of user
-**   table rows that should be considered when generating sqlite_stat1 data.
-**
-**   Examples:
-**
-**     // Do not generate any sqlite_stat1 data
-**     sqlite3_expert_config(pExpert, EXPERT_CONFIG_SAMPLE, 0);

-/*** Document lists ***
- *
- * A document list holds a sorted list of varint-encoded document IDs.
- *
- * A doclist with type DL_POSITIONS_OFFSETS is stored like this:
- *
- * array {
- *   varint docid;
- *   array {
- *     varint position;     (delta from previous position plus POS_BASE)
- *     varint startOffset;  (delta from previous startOffset)
- *     varint endOffset;    (delta from startOffset)
- *   }
- * }
- *
- * Here, array { X } means zero or more occurrences of X, adjacent in memory.
- *
- * A position list may hold positions for text in multiple columns.  A position
- * POS_COLUMN is followed by a varint containing the index of the column for
- * following positions in the list.  Any positions appearing before any
- * occurrences of POS_COLUMN are for column 0.
- *
- * A doclist with type DL_POSITIONS is like the above, but holds only docids
- * and positions without offset information.
- *
- * A doclist with type DL_DOCIDS is like the above, but holds only docids
- * without positions or offset information.
- *
- * On disk, every document list has positions and offsets, so we don't bother
- * to serialize a doclist's type.
- * 
- * We don't yet delta-encode document IDs; doing so will probably be a
- * modest win.
- *
- * NOTE(shess) I've thought of a slightly (1%) better offset encoding.
- * After the first offset, estimate the next offset by using the
- * current token position and the previous token position and offset,
- * offset to handle some variance.  So the estimate would be
- * (iPosition*w->iStartOffset/w->iPosition-64), which is delta-encoded
- * as normal.  Offsets more than 64 chars from the estimate are
- * encoded as the delta to the previous start offset + 128.  An
- * additional tiny increment can be gained by using the end offset of
- * the previous token to make the estimate a tiny bit more precise.

-/*** Document lists ***
- *
- * A document list holds a sorted list of varint-encoded document IDs.
- *
- * A doclist with type DL_POSITIONS_OFFSETS is stored like this:
- *
- * array {
- *   varint docid;
- *   array {
- *     varint position;     (delta from previous position plus 1, or 0 for end)
- *     varint startOffset;  (delta from previous startOffset)
- *     varint endOffset;    (delta from startOffset)
- *   }
- * }
- *
- * Here, array { X } means zero or more occurrences of X, adjacent in memory.
- *
- * A doclist with type DL_POSITIONS is like the above, but holds only docids
- * and positions without offset information.
- *
- * A doclist with type DL_DOCIDS is like the above, but holds only docids
- * without positions or offset information.
- *
- * On disk, every document list has positions and offsets, so we don't bother
- * to serialize a doclist's type.
- * 
- * We don't yet delta-encode document IDs; doing so will probably be a
- * modest win.
- *
- * NOTE(shess) I've thought of a slightly (1%) better offset encoding.
- * After the first offset, estimate the next offset by using the
- * current token position and the previous token position and offset,
- * offset to handle some variance.  So the estimate would be
- * (iPosition*w->iStartOffset/w->iPosition-64), which is delta-encoded
- * as normal.  Offsets more than 64 chars from the estimate are
- * encoded as the delta to the previous start offset + 128.  An
- * additional tiny increment can be gained by using the end offset of
- * the previous token to make the estimate a tiny bit more precise.

-
-1. FTS2 Tokenizers
-
-  When creating a new full-text table, FTS2 allows the user to select
-  the text tokenizer implementation to be used when indexing text
-  by specifying a "tokenizer" clause as part of the CREATE VIRTUAL TABLE
-  statement:
-
-    CREATE VIRTUAL TABLE <table-name> USING fts2(
-      <columns ...> [, tokenizer <tokenizer-name> [<tokenizer-args>]]
-    );
-
-  The built-in tokenizers (valid values to pass as <tokenizer name>) are
-  "simple" and "porter".
-
-  <tokenizer-args> should consist of zero or more white-space separated
-  arguments to pass to the selected tokenizer implementation. The 
-  interpretation of the arguments, if any, depends on the individual 
-  tokenizer.
-
-2. Custom Tokenizers
-
-  FTS2 allows users to provide custom tokenizer implementations. The 
-  interface used to create a new tokenizer is defined and described in 
-  the fts2_tokenizer.h source file.
-
-  Registering a new FTS2 tokenizer is similar to registering a new 
-  virtual table module with SQLite. The user passes a pointer to a
-  structure containing pointers to various callback functions that
-  make up the implementation of the new tokenizer type. For tokenizers,
-  the structure (defined in fts2_tokenizer.h) is called
-  "sqlite3_tokenizer_module".
-
-  FTS2 does not expose a C-function that users call to register new
-  tokenizer types with a database handle. Instead, the pointer must
-  be encoded as an SQL blob value and passed to FTS2 through the SQL
-  engine by evaluating a special scalar function, "fts2_tokenizer()".
-  The fts2_tokenizer() function may be called with one or two arguments,
-  as follows:
-
-    SELECT fts2_tokenizer(<tokenizer-name>);
-    SELECT fts2_tokenizer(<tokenizer-name>, <sqlite3_tokenizer_module ptr>);
-  
-  Where <tokenizer-name> is a string identifying the tokenizer and
-  <sqlite3_tokenizer_module ptr> is a pointer to an sqlite3_tokenizer_module
-  structure encoded as an SQL blob. If the second argument is present,
-  it is registered as tokenizer <tokenizer-name> and a copy of it
-  returned. If only one argument is passed, a pointer to the tokenizer
-  implementation currently registered as <tokenizer-name> is returned,
-  encoded as a blob. Or, if no such tokenizer exists, an SQL exception
-  (error) is raised.
-
-  SECURITY: If the fts2 extension is used in an environment where potentially
-    malicious users may execute arbitrary SQL (i.e. gears), they should be
-    prevented from invoking the fts2_tokenizer() function, possibly using the
-    authorisation callback.
-
-  See "Sample code" below for an example of calling the fts2_tokenizer()
-  function from C code.
-
-3. ICU Library Tokenizers
-
-  If this extension is compiled with the SQLITE_ENABLE_ICU pre-processor 
-  symbol defined, then there exists a built-in tokenizer named "icu" 
-  implemented using the ICU library. The first argument passed to the
-  xCreate() method (see fts2_tokenizer.h) of this tokenizer may be
-  an ICU locale identifier. For example "tr_TR" for Turkish as used
-  in Turkey, or "en_AU" for English as used in Australia. For example:
-
-    "CREATE VIRTUAL TABLE thai_text USING fts2(text, tokenizer icu th_TH)"
-
-  The ICU tokenizer implementation is very simple. It splits the input
-  text according to the ICU rules for finding word boundaries and discards
-  any tokens that consist entirely of white-space. This may be suitable
-  for some applications in some locales, but not all. If more complex
-  processing is required, for example to implement stemming or 
-  discard punctuation, this can be done by creating a tokenizer 
-  implementation that uses the ICU tokenizer as part of its implementation.
-
-  When using the ICU tokenizer this way, it is safe to overwrite the
-  contents of the strings returned by the xNext() method (see
-  fts2_tokenizer.h).
-
-4. Sample code.
-
-  The following two code samples illustrate the way C code should invoke
-  the fts2_tokenizer() scalar function:
-
-      int registerTokenizer(
-        sqlite3 *db, 
-        char *zName, 
-        const sqlite3_tokenizer_module *p
-      ){
-        int rc;
-        sqlite3_stmt *pStmt;
-        const char zSql[] = "SELECT fts2_tokenizer(?, ?)";
-      
-        rc = sqlite3_prepare_v2(db, zSql, -1, &pStmt, 0);
-        if( rc!=SQLITE_OK ){
-          return rc;
-        }
-      
-        sqlite3_bind_text(pStmt, 1, zName, -1, SQLITE_STATIC);
-        sqlite3_bind_blob(pStmt, 2, &p, sizeof(p), SQLITE_STATIC);
-        sqlite3_step(pStmt);
-      
-        return sqlite3_finalize(pStmt);
-      }
-      
-      int queryTokenizer(
-        sqlite3 *db, 
-        char *zName,  
-        const sqlite3_tokenizer_module **pp
-      ){
-        int rc;
-        sqlite3_stmt *pStmt;
-        const char zSql[] = "SELECT fts2_tokenizer(?)";
-      
-        *pp = 0;
-        rc = sqlite3_prepare_v2(db, zSql, -1, &pStmt, 0);
-        if( rc!=SQLITE_OK ){
-          return rc;
-        }
-      
-        sqlite3_bind_text(pStmt, 1, zName, -1, SQLITE_STATIC);
-        if( SQLITE_ROW==sqlite3_step(pStmt) ){
-          if( sqlite3_column_type(pStmt, 0)==SQLITE_BLOB ){
-            memcpy(pp, sqlite3_column_blob(pStmt, 0), sizeof(*pp));
-          }
-        }
-      
-        return sqlite3_finalize(pStmt);
-      }

-** are built from the bottom up, things will be described from the
-** bottom up.
-**
-**
-**** Varints ****
-** The basic unit of encoding is a variable-length integer called a
-** varint.  We encode variable-length integers in little-endian order
-** using seven bits * per byte as follows:
-**
-** KEY:
-**         A = 0xxxxxxx    7 bits of data and one flag bit
-**         B = 1xxxxxxx    7 bits of data and one flag bit
-**
-**  7 bits - A
-** 14 bits - BA
-** 21 bits - BBA
-** and so on.
-**
-** This is identical to how sqlite encodes varints (see util.c).
-**
-**
-**** Document lists ****
-** A doclist (document list) holds a docid-sorted list of hits for a
-** given term.  Doclists hold docids, and can optionally associate
-** token positions and offsets with docids.
-**
-** A DL_POSITIONS_OFFSETS doclist is stored like this:
-**
-** array {
-**   varint docid;
-**   array {                (position list for column 0)
-**     varint position;     (delta from previous position plus POS_BASE)
-**     varint startOffset;  (delta from previous startOffset)
-**     varint endOffset;    (delta from startOffset)
-**   }
-**   array {
-**     varint POS_COLUMN;   (marks start of position list for new column)
-**     varint column;       (index of new column)
-**     array {
-**       varint position;   (delta from previous position plus POS_BASE)
-**       varint startOffset;(delta from previous startOffset)
-**       varint endOffset;  (delta from startOffset)
-**     }
-**   }
-**   varint POS_END;        (marks end of positions for this document.
-** }
-**
-** Here, array { X } means zero or more occurrences of X, adjacent in
-** memory.  A "position" is an index of a token in the token stream
-** generated by the tokenizer, while an "offset" is a byte offset,
-** both based at 0.  Note that POS_END and POS_COLUMN occur in the
-** same logical place as the position element, and act as sentinals
-** ending a position list array.
-**
-** A DL_POSITIONS doclist omits the startOffset and endOffset
-** information.  A DL_DOCIDS doclist omits both the position and
-** offset information, becoming an array of varint-encoded docids.
-**
-** On-disk data is stored as type DL_DEFAULT, so we don't serialize
-** the type.  Due to how deletion is implemented in the segmentation
-** system, on-disk doclists MUST store at least positions.
-**
-**
-**** Segment leaf nodes ****
-** Segment leaf nodes store terms and doclists, ordered by term.  Leaf
-** nodes are written using LeafWriter, and read using LeafReader (to
-** iterate through a single leaf node's data) and LeavesReader (to
-** iterate through a segment's entire leaf layer).  Leaf nodes have
-** the format:
-**
-** varint iHeight;             (height from leaf level, always 0)
-** varint nTerm;               (length of first term)
-** char pTerm[nTerm];          (content of first term)
-** varint nDoclist;            (length of term's associated doclist)
-** char pDoclist[nDoclist];    (content of doclist)
-** array {
-**                             (further terms are delta-encoded)
-**   varint nPrefix;           (length of prefix shared with previous term)
-**   varint nSuffix;           (length of unshared suffix)
-**   char pTermSuffix[nSuffix];(unshared suffix of next term)
-**   varint nDoclist;          (length of term's associated doclist)
-**   char pDoclist[nDoclist];  (content of doclist)
-** }
-**
-** Here, array { X } means zero or more occurrences of X, adjacent in
-** memory.
-**
-** Leaf nodes are broken into blocks which are stored contiguously in
-** the %_segments table in sorted order.  This means that when the end
-** of a node is reached, the next term is in the node with the next
-** greater node id.
-**
-** New data is spilled to a new leaf node when the current node
-** exceeds LEAF_MAX bytes (default 2048).  New data which itself is
-** larger than STANDALONE_MIN (default 1024) is placed in a standalone
-** node (a leaf node with a single term and doclist).  The goal of
-** these settings is to pack together groups of small doclists while
-** making it efficient to directly access large doclists.  The
-** assumption is that large doclists represent terms which are more
-** likely to be query targets.
-**
-** TODO(shess) It may be useful for blocking decisions to be more
-** dynamic.  For instance, it may make more sense to have a 2.5k leaf
-** node rather than splitting into 2k and .5k nodes.  My intuition is
-** that this might extend through 2x or 4x the pagesize.
-**
-**
-**** Segment interior nodes ****
-** Segment interior nodes store blockids for subtree nodes and terms
-** to describe what data is stored by the each subtree.  Interior
-** nodes are written using InteriorWriter, and read using
-** InteriorReader.  InteriorWriters are created as needed when
-** SegmentWriter creates new leaf nodes, or when an interior node
-** itself grows too big and must be split.  The format of interior
-** nodes:
-**
-** varint iHeight;           (height from leaf level, always >0)
-** varint iBlockid;          (block id of node's leftmost subtree)
-** optional {
-**   varint nTerm;           (length of first term)
-**   char pTerm[nTerm];      (content of first term)
-**   array {
-**                                (further terms are delta-encoded)
-**     varint nPrefix;            (length of shared prefix with previous term)
-**     varint nSuffix;            (length of unshared suffix)
-**     char pTermSuffix[nSuffix]; (unshared suffix of next term)
-**   }
-** }
-**
-** Here, optional { X } means an optional element, while array { X }
-** means zero or more occurrences of X, adjacent in memory.
-**
-** An interior node encodes n terms separating n+1 subtrees.  The
-** subtree blocks are contiguous, so only the first subtree's blockid
-** is encoded.  The subtree at iBlockid will contain all terms less
-** than the first term encoded (or all terms if no term is encoded).
-** Otherwise, for terms greater than or equal to pTerm[i] but less
-** than pTerm[i+1], the subtree for that term will be rooted at
-** iBlockid+i.  Interior nodes only store enough term data to
-** distinguish adjacent children (if the rightmost term of the left
-** child is "something", and the leftmost term of the right child is
-** "wicked", only "w" is stored).
-**
-** New data is spilled to a new interior node at the same height when
-** the current node exceeds INTERIOR_MAX bytes (default 2048).
-** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing
-** interior nodes and making the tree too skinny.  The interior nodes
-** at a given height are naturally tracked by interior nodes at
-** height+1, and so on.
-**
-**
-**** Segment directory ****
-** The segment directory in table %_segdir stores meta-information for
-** merging and deleting segments, and also the root node of the
-** segment's tree.
-**
-** The root node is the top node of the segment's tree after encoding
-** the entire segment, restricted to ROOT_MAX bytes (default 1024).
-** This could be either a leaf node or an interior node.  If the top
-** node requires more than ROOT_MAX bytes, it is flushed to %_segments
-** and a new root interior node is generated (which should always fit
-** within ROOT_MAX because it only needs space for 2 varints, the
-** height and the blockid of the previous root).
-**
-** The meta-information in the segment directory is:
-**   level               - segment level (see below)
-**   idx                 - index within level
-**                       - (level,idx uniquely identify a segment)
-**   start_block         - first leaf node
-**   leaves_end_block    - last leaf node
-**   end_block           - last block (including interior nodes)
-**   root                - contents of root node
-**
-** If the root node is a leaf node, then start_block,
-** leaves_end_block, and end_block are all 0.
-**
-**
-**** Segment merging ****
-** To amortize update costs, segments are groups into levels and
-** merged in matches.  Each increase in level represents exponentially
-** more documents.
-**
-** New documents (actually, document updates) are tokenized and
-** written individually (using LeafWriter) to a level 0 segment, with
-** incrementing idx.  When idx reaches MERGE_COUNT (default 16), all
-** level 0 segments are merged into a single level 1 segment.  Level 1
-** is populated like level 0, and eventually MERGE_COUNT level 1
-** segments are merged to a single level 2 segment (representing
-** MERGE_COUNT^2 updates), and so on.
-**
-** A segment merge traverses all segments at a given level in
-** parallel, performing a straightforward sorted merge.  Since segment
-** leaf nodes are written in to the %_segments table in order, this
-** merge traverses the underlying sqlite disk structures efficiently.
-** After the merge, all segment blocks from the merged level are
-** deleted.
-**
-** MERGE_COUNT controls how often we merge segments.  16 seems to be
-** somewhat of a sweet spot for insertion performance.  32 and 64 show
-** very similar performance numbers to 16 on insertion, though they're
-** a tiny bit slower (perhaps due to more overhead in merge-time
-** sorting).  8 is about 20% slower than 16, 4 about 50% slower than
-** 16, 2 about 66% slower than 16.
-**
-** At query time, high MERGE_COUNT increases the number of segments
-** which need to be scanned and merged.  For instance, with 100k docs
-** inserted:
-**
-**    MERGE_COUNT   segments
-**       16           25
-**        8           12
-**        4           10
-**        2            6
-**
-** This appears to have only a moderate impact on queries for very
-** frequent terms (which are somewhat dominated by segment merge
-** costs), and infrequent and non-existent terms still seem to be fast
-** even with many segments.
-**
-** TODO(shess) That said, it would be nice to have a better query-side
-** argument for MERGE_COUNT of 16.  Also, it is possible/likely that
-** optimizations to things like doclist merging will swing the sweet
-** spot around.
-**
-**
-**
-**** Handling of deletions and updates ****
-** Since we're using a segmented structure, with no docid-oriented
-** index into the term index, we clearly cannot simply update the term
-** index when a document is deleted or updated.  For deletions, we
-** write an empty doclist (varint(docid) varint(POS_END)), for updates
-** we simply write the new doclist.  Segment merges overwrite older
-** data for a particular docid with newer data, so deletes or updates
-** will eventually overtake the earlier data and knock it out.  The
-** query logic likewise merges doclists so that newer data knocks out
-** older data.
-**
-** TODO(shess) Provide a VACUUM type operation to clear out all
-** deletions and duplications.  This would basically be a forced merge
-** into a single segment.

- * A "-" before a term matches all entries that lack that term.
- * The "-" must occur immediately before the term with in intervening
- * space.  This is how the search engines do it.
- *
- * A NOT term cannot be the right-hand operand of an OR.  If this
- * occurs in the query string, the NOT is ignored:

-FTS4 CONTENT OPTION
-
-  Normally, in order to create a full-text index on a dataset, the FTS4 
-  module stores a copy of all indexed documents in a specially created 
-  database table.
-
-  As of SQLite version 3.7.9, FTS4 supports a new option - "content" -
-  designed to extend FTS4 to support the creation of full-text indexes where:
-
-    * The indexed documents are not stored within the SQLite database 
-      at all (a "contentless" FTS4 table), or
-
-    * The indexed documents are stored in a database table created and
-      managed by the user (an "external content" FTS4 table).
-
-  Because the indexed documents themselves are usually much larger than 
-  the full-text index, the content option can sometimes be used to achieve 
-  significant space savings.
-
-CONTENTLESS FTS4 TABLES
-
-  In order to create an FTS4 table that does not store a copy of the indexed
-  documents at all, the content option should be set to an empty string.
-  For example, the following SQL creates such an FTS4 table with three
-  columns - "a", "b", and "c":
-
-    CREATE VIRTUAL TABLE t1 USING fts4(content="", a, b, c);
-
-  Data can be inserted into such an FTS4 table using an INSERT statements.
-  However, unlike ordinary FTS4 tables, the user must supply an explicit
-  integer docid value. For example:
-
-    -- This statement is Ok:
-    INSERT INTO t1(docid, a, b, c) VALUES(1, 'a b c', 'd e f', 'g h i');
-
-    -- This statement causes an error, as no docid value has been provided:
-    INSERT INTO t1(a, b, c) VALUES('j k l', 'm n o', 'p q r');
-
-  It is not possible to UPDATE or DELETE a row stored in a contentless FTS4
-  table. Attempting to do so is an error.
-
-  Contentless FTS4 tables also support SELECT statements. However, it is
-  an error to attempt to retrieve the value of any table column other than
-  the docid column. The auxiliary function matchinfo() may be used, but
-  snippet() and offsets() may not. For example:
-
-    -- The following statements are Ok:
-    SELECT docid FROM t1 WHERE t1 MATCH 'xxx';
-    SELECT docid FROM t1 WHERE a MATCH 'xxx';
-    SELECT matchinfo(t1) FROM t1 WHERE t1 MATCH 'xxx';
-
-    -- The following statements all cause errors, as the value of columns
-    -- other than docid are required to evaluate them.
-    SELECT * FROM t1;
-    SELECT a, b FROM t1 WHERE t1 MATCH 'xxx';
-    SELECT docid FROM t1 WHERE a LIKE 'xxx%';
-    SELECT snippet(t1) FROM t1 WHERE t1 MATCH 'xxx';
-
-  Errors related to attempting to retrieve column values other than docid
-  are runtime errors that occur within sqlite3_step(). In some cases, for
-  example if the MATCH expression in a SELECT query matches zero rows, there
-  may be no error at all even if a statement does refer to column values 
-  other than docid.
-
-EXTERNAL CONTENT FTS4 TABLES
-
-  An "external content" FTS4 table is similar to a contentless table, except
-  that if evaluation of a query requires the value of a column other than 
-  docid, FTS4 attempts to retrieve that value from a table (or view, or 
-  virtual table) nominated by the user (hereafter referred to as the "content
-  table"). The FTS4 module never writes to the content table, and writing
-  to the content table does not affect the full-text index. It is the
-  responsibility of the user to ensure that the content table and the 
-  full-text index are consistent.
-
-  An external content FTS4 table is created by setting the content option
-  to the name of a table (or view, or virtual table) that may be queried by
-  FTS4 to retrieve column values when required. If the nominated table does
-  not exist, then an external content table behaves in the same way as
-  a contentless table. For example:
-
-    CREATE TABLE t2(id INTEGER PRIMARY KEY, a, b, c);
-    CREATE VIRTUAL TABLE t3 USING fts4(content="t2", a, c);
-
-  Assuming the nominated table does exist, then its columns must be the same 
-  as or a superset of those defined for the FTS table.
-
-  When a users query on the FTS table requires a column value other than
-  docid, FTS attempts to read this value from the corresponding column of
-  the row in the content table with a rowid value equal to the current FTS
-  docid. Or, if such a row cannot be found in the content table, a NULL
-  value is used instead. For example:
-
-    CREATE TABLE t2(id INTEGER PRIMARY KEY, a, b, c, d);
-    CREATE VIRTUAL TABLE t3 USING fts4(content="t2", b, c);
-  
-    INSERT INTO t2 VALUES(2, 'a b', 'c d', 'e f');
-    INSERT INTO t2 VALUES(3, 'g h', 'i j', 'k l');
-    INSERT INTO t3(docid, b, c) SELECT id, b, c FROM t2;
-
-    -- The following query returns a single row with two columns containing
-    -- the text values "i j" and "k l".
-    --
-    -- The query uses the full-text index to discover that the MATCH 
-    -- term matches the row with docid=3. It then retrieves the values
-    -- of columns b and c from the row with rowid=3 in the content table
-    -- to return.
-    --
-    SELECT * FROM t3 WHERE t3 MATCH 'k';
-
-    -- Following the UPDATE, the query still returns a single row, this
-    -- time containing the text values "xxx" and "yyy". This is because the
-    -- full-text index still indicates that the row with docid=3 matches
-    -- the FTS4 query 'k', even though the documents stored in the content
-    -- table have been modified.
-    --
-    UPDATE t2 SET b = 'xxx', c = 'yyy' WHERE rowid = 3;
-    SELECT * FROM t3 WHERE t3 MATCH 'k';
-
-    -- Following the DELETE below, the query returns one row containing two
-    -- NULL values. NULL values are returned because FTS is unable to find
-    -- a row with rowid=3 within the content table.
-    --
-    DELETE FROM t2;
-    SELECT * FROM t3 WHERE t3 MATCH 'k';
-
-  When a row is deleted from an external content FTS4 table, FTS4 needs to
-  retrieve the column values of the row being deleted from the content table.
-  This is so that FTS4 can update the full-text index entries for each token
-  that occurs within the deleted row to indicate that that row has been 
-  deleted. If the content table row cannot be found, or if it contains values
-  inconsistent with the contents of the FTS index, the results can be difficult
-  to predict. The FTS index may be left containing entries corresponding to the
-  deleted row, which can lead to seemingly nonsensical results being returned
-  by subsequent SELECT queries. The same applies when a row is updated, as
-  internally an UPDATE is the same as a DELETE followed by an INSERT.
-  
-  Instead of writing separately to the full-text index and the content table,
-  some users may wish to use database triggers to keep the full-text index
-  up to date with respect to the set of documents stored in the content table.
-  For example, using the tables from earlier examples:
-
-    CREATE TRIGGER t2_bu BEFORE UPDATE ON t2 BEGIN
-      DELETE FROM t3 WHERE docid=old.rowid;
-    END;
-    CREATE TRIGGER t2_bd BEFORE DELETE ON t2 BEGIN
-      DELETE FROM t3 WHERE docid=old.rowid;
-    END;
-
-    CREATE TRIGGER t2_bu AFTER UPDATE ON t2 BEGIN
-      INSERT INTO t3(docid, b, c) VALUES(new.rowid, new.b, new.c);
-    END;
-    CREATE TRIGGER t2_bd AFTER INSERT ON t2 BEGIN
-      INSERT INTO t3(docid, b, c) VALUES(new.rowid, new.b, new.c);
-    END;
-
-  The DELETE trigger must be fired before the actual delete takes place
-  on the content table. This is so that FTS4 can still retrieve the original
-  values in order to update the full-text index. And the INSERT trigger must
-  be fired after the new row is inserted, so as to handle the case where the
-  rowid is assigned automatically within the system. The UPDATE trigger must
-  be split into two parts, one fired before and one after the update of the
-  content table, for the same reasons.
-
-  FTS4 features a special command similar to the 'optimize' command that
-  deletes the entire full-text index and rebuilds it based on the current
-  set of documents in the content table. Assuming again that "t3" is the
-  name of the external content FTS4 table, the command is:
-
-    INSERT INTO t3(t3) VALUES('rebuild');
-
-  This command may also be used with ordinary FTS4 tables, although it may
-  only be useful if the full-text index has somehow become corrupt. It is an
-  error to attempt to rebuild the full-text index maintained by a contentless
-  FTS4 table.

-1. OVERVIEW
-
-  This README file describes the syntax of the arguments that may be passed to
-  the FTS3 MATCH operator used for full-text queries. For example, if table 
-  "t1" is an Fts3 virtual table, the following SQL query:
-
-    SELECT * FROM t1 WHERE <col> MATCH <full-text query>
-
-  may be used to retrieve all rows that match a specified for full-text query. 
-  The text "<col>" should be replaced by either the name of the fts3 table 
-  (in this case "t1"), or by the name of one of the columns of the fts3 
-  table. <full-text-query> should be replaced by an SQL expression that 
-  computes to a string containing an Fts3 query.
-
-  If the left-hand-side of the MATCH operator is set to the name of the
-  fts3 table, then by default the query may be matched against any column
-  of the table. If it is set to a column name, then by default the query
-  may only match the specified column. In both cases this may be overriden
-  as part of the query text (see sections 2 and 3 below).
-
-  As of SQLite version 3.6.8, Fts3 supports two slightly different query 
-  formats; the standard syntax, which is used by default, and the enhanced
-  query syntax which can be selected by compiling with the pre-processor
-  symbol SQLITE_ENABLE_FTS3_PARENTHESIS defined.
-
-    -DSQLITE_ENABLE_FTS3_PARENTHESIS
-
-2. STANDARD QUERY SYNTAX
-
-  When using the standard Fts3 query syntax, a query usually consists of a 
-  list of terms (words) separated by white-space characters. To match a
-  query, a row (or column) of an Fts3 table must contain each of the specified
-  terms. For example, the following query:
-
-    <col> MATCH 'hello world'
-
-  matches rows (or columns, if <col> is the name of a column name) that 
-  contain at least one instance of the token "hello", and at least one 
-  instance of the token "world". Tokens may be grouped into phrases using
-  quotation marks. In this case, a matching row or column must contain each
-  of the tokens in the phrase in the order specified, with no intervening
-  tokens. For example, the query:
-
-    <col> MATCH '"hello world" joe"
-
-  matches the first of the following two documents, but not the second or
-  third:
-
-    "'Hello world', said Joe."
-    "One should always greet the world with a cheery hello, thought Joe."
-    "How many hello world programs could their be?"
-
-  As well as grouping tokens together by phrase, the binary NEAR operator 
-  may be used to search for rows that contain two or more specified tokens 
-  or phrases within a specified proximity of each other. The NEAR operator
-  must always be specified in upper case. The word "near" in lower or mixed
-  case is treated as an ordinary token. For example, the following query:
-
-    <col> MATCH 'engineering NEAR consultancy'
-
-  matches rows that contain both the "engineering" and "consultancy" tokens
-  in the same column with not more than 10 other words between them. It does
-  not matter which of the two terms occurs first in the document, only that
-  they be seperated by only 10 tokens or less. The user may also specify
-  a different required proximity by adding "/N" immediately after the NEAR
-  operator, where N is an integer. For example:
-
-    <col> MATCH 'engineering NEAR/5 consultancy'
-
-  searches for a row containing an instance of each specified token seperated
-  by not more than 5 other tokens. More than one NEAR operator can be used
-  in as sequence. For example this query:
-
-    <col> MATCH 'reliable NEAR/2 engineering NEAR/5 consultancy'
-
-  searches for a row that contains an instance of the token "reliable" 
-  seperated by not more than two tokens from an instance of "engineering",
-  which is in turn separated by not more than 5 other tokens from an
-  instance of the term "consultancy". Phrases enclosed in quotes may
-  also be used as arguments to the NEAR operator.
-
-  Similar to the NEAR operator, one or more tokens or phrases may be 
-  separated by OR operators. In this case, only one of the specified tokens
-  or phrases must appear in the document. For example, the query:
-
-    <col> MATCH 'hello OR world'
-
-  matches rows that contain either the term "hello", or the term "world",
-  or both. Note that unlike in many programming languages, the OR operator
-  has a higher precedence than the AND operators implied between white-space
-  separated tokens. The following query matches documents that contain the
-  term 'sqlite' and at least one of the terms 'fantastic' or 'impressive',
-  not those that contain both 'sqlite' and 'fantastic' or 'impressive':
-
-    <col> MATCH 'sqlite fantastic OR impressive'
-
-  Any token that is part of an Fts3 query expression, whether or not it is
-  part of a phrase enclosed in quotes, may have a '*' character appended to
-  it. In this case, the token matches all terms that begin with the characters
-  of the token, not just those that exactly match it. For example, the 
-  following query:
-
-    <col> MATCH 'sql*'
-
-  matches all rows that contain the term "SQLite", as well as those that
-  contain "SQL".
-
-  A token that is not part of a quoted phrase may be preceded by a '-'
-  character, which indicates that matching rows must not contain the 
-  specified term. For example, the following:
-
-    <col> MATCH '"database engine" -sqlite'
-
-  matches rows that contain the phrase "database engine" but do not contain
-  the term "sqlite". If the '-' character occurs inside a quoted phrase,
-  it is ignored. It is possible to use both the '-' prefix and the '*' postfix
-  on a single term. At this time, all Fts3 queries must contain at least
-  one term or phrase that is not preceded by the '-' prefix.
-
-  Regardless of whether or not a table name or column name is used on the 
-  left hand side of the MATCH operator, a specific column of the fts3 table
-  may be associated with each token in a query by preceding a token with
-  a column name followed by a ':' character. For example, regardless of what
-  is specified for <col>, the following query requires that column "col1"
-  of the table contains the term "hello", and that column "col2" of the
-  table contains the term "world". If the table does not contain columns
-  named "col1" and "col2", then an error is returned and the query is
-  not run.
-
-    <col> MATCH 'col1:hello col2:world'
-
-  It is not possible to associate a specific table column with a quoted 
-  phrase or a term preceded by a '-' operator. A '*' character may be
-  appended to a term associated with a specific column for prefix matching.
-
-3. ENHANCED QUERY SYNTAX
-
-  The enhanced query syntax is quite similar to the standard query syntax,
-  with the following four differences:
-
-  1) Parenthesis are supported. When using the enhanced query syntax,
-     parenthesis may be used to overcome the built-in precedence of the
-     supplied binary operators. For example, the following query:
-
-       <col> MATCH '(hello world) OR (simple example)'
-
-     matches documents that contain both "hello" and "world", and documents
-     that contain both "simple" and "example". It is not possible to forumlate
-     such a query using the standard syntax.
-
-  2) Instead of separating tokens and phrases by whitespace, an AND operator
-     may be explicitly specified. This does not change query processing at
-     all, but may be used to improve readability. For example, the following
-     query is handled identically to the one above:
-
-       <col> MATCH '(hello AND world) OR (simple AND example)'
-
-     As with the OR and NEAR operators, the AND operator must be specified
-     in upper case. The word "and" specified in lower or mixed case is 
-     handled as a regular token.
-
-  3) The '-' token prefix is not supported. Instead, a new binary operator,
-     NOT, is included. The NOT operator requires that the query specified
-     as its left-hand operator matches, but that the query specified as the
-     right-hand operator does not. For example, to query for all rows that
-     contain the term "example" but not the term "simple", the following
-     query could be used:
-
-       <col> MATCH 'example NOT simple'
-
-     As for all other operators, the NOT operator must be specified in
-     upper case. Otherwise it will be treated as a regular token.
-
-  4) Unlike in the standard syntax, where the OR operator has a higher
-     precedence than the implicit AND operator, when using the enhanced
-     syntax implicit and explict AND operators have a higher precedence
-     than OR operators. Using the enhanced syntax, the following two
-     queries are equivalent:
-
-       <col> MATCH 'sqlite fantastic OR impressive'
-       <col> MATCH '(sqlite AND fantastic) OR impressive'
-
-     however, when using the standard syntax, the query:
-
-       <col> MATCH 'sqlite fantastic OR impressive'
-
-     is equivalent to the enhanced syntax query:
-
-       <col> MATCH 'sqlite AND (fantastic OR impressive)'
-
-     The precedence of all enhanced syntax operators, in order from highest
-     to lowest, is:
-
-       NEAR       (highest precedence, tightest grouping)
-       NOT
-       AND
-       OR         (lowest precedence, loosest grouping)
-
-  Using the advanced syntax, it is possible to specify expressions enclosed
-  in parenthesis as operands to the NOT, AND and OR operators. However both
-  the left and right hand side operands of NEAR operators must be either
-  tokens or phrases. Attempting the following query will return an error:
-
-    <col> MATCH 'sqlite NEAR (fantastic OR impressive)'
-
-  Queries of this form must be re-written as:
-
-    <col> MATCH 'sqlite NEAR fantastic OR sqlite NEAR impressive'

-1. FTS3 Tokenizers
-
-  When creating a new full-text table, FTS3 allows the user to select
-  the text tokenizer implementation to be used when indexing text
-  by specifying a "tokenize" clause as part of the CREATE VIRTUAL TABLE
-  statement:
-
-    CREATE VIRTUAL TABLE <table-name> USING fts3(
-      <columns ...> [, tokenize <tokenizer-name> [<tokenizer-args>]]
-    );
-
-  The built-in tokenizers (valid values to pass as <tokenizer name>) are
-  "simple", "porter" and "unicode".
-
-  <tokenizer-args> should consist of zero or more white-space separated
-  arguments to pass to the selected tokenizer implementation. The 
-  interpretation of the arguments, if any, depends on the individual 
-  tokenizer.
-
-2. Custom Tokenizers
-
-  FTS3 allows users to provide custom tokenizer implementations. The 
-  interface used to create a new tokenizer is defined and described in 
-  the fts3_tokenizer.h source file.
-
-  Registering a new FTS3 tokenizer is similar to registering a new 
-  virtual table module with SQLite. The user passes a pointer to a
-  structure containing pointers to various callback functions that
-  make up the implementation of the new tokenizer type. For tokenizers,
-  the structure (defined in fts3_tokenizer.h) is called
-  "sqlite3_tokenizer_module".
-
-  FTS3 does not expose a C-function that users call to register new
-  tokenizer types with a database handle. Instead, the pointer must
-  be encoded as an SQL blob value and passed to FTS3 through the SQL
-  engine by evaluating a special scalar function, "fts3_tokenizer()".
-  The fts3_tokenizer() function may be called with one or two arguments,
-  as follows:
-
-    SELECT fts3_tokenizer(<tokenizer-name>);
-    SELECT fts3_tokenizer(<tokenizer-name>, <sqlite3_tokenizer_module ptr>);
-  
-  Where <tokenizer-name> is a string identifying the tokenizer and
-  <sqlite3_tokenizer_module ptr> is a pointer to an sqlite3_tokenizer_module
-  structure encoded as an SQL blob. If the second argument is present,
-  it is registered as tokenizer <tokenizer-name> and a copy of it
-  returned. If only one argument is passed, a pointer to the tokenizer
-  implementation currently registered as <tokenizer-name> is returned,
-  encoded as a blob. Or, if no such tokenizer exists, an SQL exception
-  (error) is raised.
-
-  SECURITY: If the fts3 extension is used in an environment where potentially
-    malicious users may execute arbitrary SQL (i.e. gears), they should be
-    prevented from invoking the fts3_tokenizer() function, possibly using the
-    authorisation callback.
-
-  See "Sample code" below for an example of calling the fts3_tokenizer()
-  function from C code.
-
-3. ICU Library Tokenizers
-
-  If this extension is compiled with the SQLITE_ENABLE_ICU pre-processor 
-  symbol defined, then there exists a built-in tokenizer named "icu" 
-  implemented using the ICU library. The first argument passed to the
-  xCreate() method (see fts3_tokenizer.h) of this tokenizer may be
-  an ICU locale identifier. For example "tr_TR" for Turkish as used
-  in Turkey, or "en_AU" for English as used in Australia. For example:
-
-    "CREATE VIRTUAL TABLE thai_text USING fts3(text, tokenizer icu th_TH)"
-
-  The ICU tokenizer implementation is very simple. It splits the input
-  text according to the ICU rules for finding word boundaries and discards
-  any tokens that consist entirely of white-space. This may be suitable
-  for some applications in some locales, but not all. If more complex
-  processing is required, for example to implement stemming or 
-  discard punctuation, this can be done by creating a tokenizer 
-  implementation that uses the ICU tokenizer as part of its implementation.
-
-  When using the ICU tokenizer this way, it is safe to overwrite the
-  contents of the strings returned by the xNext() method (see
-  fts3_tokenizer.h).
-
-4. Sample code.
-
-  The following two code samples illustrate the way C code should invoke
-  the fts3_tokenizer() scalar function:
-
-      int registerTokenizer(
-        sqlite3 *db, 
-        char *zName, 
-        const sqlite3_tokenizer_module *p
-      ){
-        int rc;
-        sqlite3_stmt *pStmt;
-        const char zSql[] = "SELECT fts3_tokenizer(?, ?)";
-      
-        rc = sqlite3_prepare_v2(db, zSql, -1, &pStmt, 0);
-        if( rc!=SQLITE_OK ){
-          return rc;
-        }
-      
-        sqlite3_bind_text(pStmt, 1, zName, -1, SQLITE_STATIC);
-        sqlite3_bind_blob(pStmt, 2, &p, sizeof(p), SQLITE_STATIC);
-        sqlite3_step(pStmt);
-      
-        return sqlite3_finalize(pStmt);
-      }
-      
-      int queryTokenizer(
-        sqlite3 *db, 
-        char *zName,  
-        const sqlite3_tokenizer_module **pp
-      ){
-        int rc;
-        sqlite3_stmt *pStmt;
-        const char zSql[] = "SELECT fts3_tokenizer(?)";
-      
-        *pp = 0;
-        rc = sqlite3_prepare_v2(db, zSql, -1, &pStmt, 0);
-        if( rc!=SQLITE_OK ){
-          return rc;
-        }
-      
-        sqlite3_bind_text(pStmt, 1, zName, -1, SQLITE_STATIC);
-        if( SQLITE_ROW==sqlite3_step(pStmt) ){
-          if( sqlite3_column_type(pStmt, 0)==SQLITE_BLOB ){
-            memcpy(pp, sqlite3_column_blob(pStmt, 0), sizeof(*pp));
-          }
-        }
-      
-        return sqlite3_finalize(pStmt);
-      }

-**
-** This is an SQLite module implementing full-text search.
-*/
-
-/*
-** The code in this file is only compiled if:
-**
-**     * The FTS3 module is being built as an extension
-**       (in which case SQLITE_CORE is not defined), or
-**

-*/
-
-/* The full-text index is stored in a series of b+tree (-like)
-** structures called segments which map terms to doclists.  The
-** structures are like b+trees in layout, but are constructed from the
-** bottom up in optimal fashion and are not updatable.  Since trees
-** are built from the bottom up, things will be described from the
-** bottom up.
-**
-**
-**** Varints ****
-** The basic unit of encoding is a variable-length integer called a
-** varint.  We encode variable-length integers in little-endian order
-** using seven bits * per byte as follows:
-**
-** KEY:
-**         A = 0xxxxxxx    7 bits of data and one flag bit
-**         B = 1xxxxxxx    7 bits of data and one flag bit
-**
-**  7 bits - A
-** 14 bits - BA
-** 21 bits - BBA
-** and so on.
-**
-** This is similar in concept to how sqlite encodes "varints" but
-** the encoding is not the same.  SQLite varints are big-endian
-** are are limited to 9 bytes in length whereas FTS3 varints are
-** little-endian and can be up to 10 bytes in length (in theory).
-**
-** Example encodings:
-**
-**     1:    0x01
-**   127:    0x7f
-**   128:    0x81 0x00
-**
-**
-**** Document lists ****
-** A doclist (document list) holds a docid-sorted list of hits for a
-** given term.  Doclists hold docids and associated token positions.
-** A docid is the unique integer identifier for a single document.
-** A position is the index of a word within the document.  The first 
-** word of the document has a position of 0.
-**
-** FTS3 used to optionally store character offsets using a compile-time
-** option.  But that functionality is no longer supported.
-**
-** A doclist is stored like this:
-**
-** array {
-**   varint docid;          (delta from previous doclist)
-**   array {                (position list for column 0)
-**     varint position;     (2 more than the delta from previous position)
-**   }
-**   array {
-**     varint POS_COLUMN;   (marks start of position list for new column)
-**     varint column;       (index of new column)
-**     array {
-**       varint position;   (2 more than the delta from previous position)
-**     }
-**   }
-**   varint POS_END;        (marks end of positions for this document.
-** }
-**
-** Here, array { X } means zero or more occurrences of X, adjacent in
-** memory.  A "position" is an index of a token in the token stream
-** generated by the tokenizer. Note that POS_END and POS_COLUMN occur 
-** in the same logical place as the position element, and act as sentinals
-** ending a position list array.  POS_END is 0.  POS_COLUMN is 1.
-** The positions numbers are not stored literally but rather as two more
-** than the difference from the prior position, or the just the position plus
-** 2 for the first position.  Example:
-**
-**   label:       A B C D E  F  G H   I  J K
-**   value:     123 5 9 1 1 14 35 0 234 72 0
-**
-** The 123 value is the first docid.  For column zero in this document
-** there are two matches at positions 3 and 10 (5-2 and 9-2+3).  The 1
-** at D signals the start of a new column; the 1 at E indicates that the
-** new column is column number 1.  There are two positions at 12 and 45
-** (14-2 and 35-2+12).  The 0 at H indicate the end-of-document.  The
-** 234 at I is the delta to next docid (357).  It has one position 70
-** (72-2) and then terminates with the 0 at K.
-**
-** A "position-list" is the list of positions for multiple columns for
-** a single docid.  A "column-list" is the set of positions for a single
-** column.  Hence, a position-list consists of one or more column-lists,
-** a document record consists of a docid followed by a position-list and
-** a doclist consists of one or more document records.
-**
-** A bare doclist omits the position information, becoming an 
-** array of varint-encoded docids.
-**
-**** Segment leaf nodes ****
-** Segment leaf nodes store terms and doclists, ordered by term.  Leaf
-** nodes are written using LeafWriter, and read using LeafReader (to
-** iterate through a single leaf node's data) and LeavesReader (to
-** iterate through a segment's entire leaf layer).  Leaf nodes have
-** the format:
-**
-** varint iHeight;             (height from leaf level, always 0)
-** varint nTerm;               (length of first term)
-** char pTerm[nTerm];          (content of first term)
-** varint nDoclist;            (length of term's associated doclist)
-** char pDoclist[nDoclist];    (content of doclist)
-** array {
-**                             (further terms are delta-encoded)
-**   varint nPrefix;           (length of prefix shared with previous term)
-**   varint nSuffix;           (length of unshared suffix)
-**   char pTermSuffix[nSuffix];(unshared suffix of next term)
-**   varint nDoclist;          (length of term's associated doclist)
-**   char pDoclist[nDoclist];  (content of doclist)
-** }
-**
-** Here, array { X } means zero or more occurrences of X, adjacent in
-** memory.
-**
-** Leaf nodes are broken into blocks which are stored contiguously in
-** the %_segments table in sorted order.  This means that when the end
-** of a node is reached, the next term is in the node with the next
-** greater node id.
-**
-** New data is spilled to a new leaf node when the current node
-** exceeds LEAF_MAX bytes (default 2048).  New data which itself is
-** larger than STANDALONE_MIN (default 1024) is placed in a standalone
-** node (a leaf node with a single term and doclist).  The goal of
-** these settings is to pack together groups of small doclists while
-** making it efficient to directly access large doclists.  The
-** assumption is that large doclists represent terms which are more
-** likely to be query targets.
-**
-** TODO(shess) It may be useful for blocking decisions to be more
-** dynamic.  For instance, it may make more sense to have a 2.5k leaf
-** node rather than splitting into 2k and .5k nodes.  My intuition is
-** that this might extend through 2x or 4x the pagesize.
-**
-**
-**** Segment interior nodes ****
-** Segment interior nodes store blockids for subtree nodes and terms
-** to describe what data is stored by the each subtree.  Interior
-** nodes are written using InteriorWriter, and read using
-** InteriorReader.  InteriorWriters are created as needed when
-** SegmentWriter creates new leaf nodes, or when an interior node
-** itself grows too big and must be split.  The format of interior
-** nodes:
-**
-** varint iHeight;           (height from leaf level, always >0)
-** varint iBlockid;          (block id of node's leftmost subtree)
-** optional {
-**   varint nTerm;           (length of first term)
-**   char pTerm[nTerm];      (content of first term)
-**   array {
-**                                (further terms are delta-encoded)
-**     varint nPrefix;            (length of shared prefix with previous term)
-**     varint nSuffix;            (length of unshared suffix)
-**     char pTermSuffix[nSuffix]; (unshared suffix of next term)
-**   }
-** }
-**
-** Here, optional { X } means an optional element, while array { X }
-** means zero or more occurrences of X, adjacent in memory.
-**
-** An interior node encodes n terms separating n+1 subtrees.  The
-** subtree blocks are contiguous, so only the first subtree's blockid
-** is encoded.  The subtree at iBlockid will contain all terms less
-** than the first term encoded (or all terms if no term is encoded).
-** Otherwise, for terms greater than or equal to pTerm[i] but less
-** than pTerm[i+1], the subtree for that term will be rooted at
-** iBlockid+i.  Interior nodes only store enough term data to
-** distinguish adjacent children (if the rightmost term of the left
-** child is "something", and the leftmost term of the right child is
-** "wicked", only "w" is stored).
-**
-** New data is spilled to a new interior node at the same height when
-** the current node exceeds INTERIOR_MAX bytes (default 2048).
-** INTERIOR_MIN_TERMS (default 7) keeps large terms from monopolizing
-** interior nodes and making the tree too skinny.  The interior nodes
-** at a given height are naturally tracked by interior nodes at
-** height+1, and so on.
-**
-**
-**** Segment directory ****
-** The segment directory in table %_segdir stores meta-information for
-** merging and deleting segments, and also the root node of the
-** segment's tree.
-**
-** The root node is the top node of the segment's tree after encoding
-** the entire segment, restricted to ROOT_MAX bytes (default 1024).
-** This could be either a leaf node or an interior node.  If the top
-** node requires more than ROOT_MAX bytes, it is flushed to %_segments
-** and a new root interior node is generated (which should always fit
-** within ROOT_MAX because it only needs space for 2 varints, the
-** height and the blockid of the previous root).
-**
-** The meta-information in the segment directory is:
-**   level               - segment level (see below)
-**   idx                 - index within level
-**                       - (level,idx uniquely identify a segment)
-**   start_block         - first leaf node
-**   leaves_end_block    - last leaf node
-**   end_block           - last block (including interior nodes)
-**   root                - contents of root node
-**
-** If the root node is a leaf node, then start_block,
-** leaves_end_block, and end_block are all 0.
-**
-**
-**** Segment merging ****
-** To amortize update costs, segments are grouped into levels and
-** merged in batches.  Each increase in level represents exponentially
-** more documents.
-**
-** New documents (actually, document updates) are tokenized and
-** written individually (using LeafWriter) to a level 0 segment, with
-** incrementing idx.  When idx reaches MERGE_COUNT (default 16), all
-** level 0 segments are merged into a single level 1 segment.  Level 1
-** is populated like level 0, and eventually MERGE_COUNT level 1
-** segments are merged to a single level 2 segment (representing
-** MERGE_COUNT^2 updates), and so on.
-**
-** A segment merge traverses all segments at a given level in
-** parallel, performing a straightforward sorted merge.  Since segment
-** leaf nodes are written in to the %_segments table in order, this
-** merge traverses the underlying sqlite disk structures efficiently.
-** After the merge, all segment blocks from the merged level are
-** deleted.
-**
-** MERGE_COUNT controls how often we merge segments.  16 seems to be
-** somewhat of a sweet spot for insertion performance.  32 and 64 show
-** very similar performance numbers to 16 on insertion, though they're
-** a tiny bit slower (perhaps due to more overhead in merge-time
-** sorting).  8 is about 20% slower than 16, 4 about 50% slower than
-** 16, 2 about 66% slower than 16.
-**
-** At query time, high MERGE_COUNT increases the number of segments
-** which need to be scanned and merged.  For instance, with 100k docs
-** inserted:
-**
-**    MERGE_COUNT   segments
-**       16           25
-**        8           12
-**        4           10
-**        2            6
-**
-** This appears to have only a moderate impact on queries for very
-** frequent terms (which are somewhat dominated by segment merge
-** costs), and infrequent and non-existent terms still seem to be fast
-** even with many segments.
-**
-** TODO(shess) That said, it would be nice to have a better query-side
-** argument for MERGE_COUNT of 16.  Also, it is possible/likely that
-** optimizations to things like doclist merging will swing the sweet
-** spot around.
-**
-**
-**
-**** Handling of deletions and updates ****
-** Since we're using a segmented structure, with no docid-oriented
-** index into the term index, we clearly cannot simply update the term
-** index when a document is deleted or updated.  For deletions, we
-** write an empty doclist (varint(docid) varint(POS_END)), for updates
-** we simply write the new doclist.  Segment merges overwrite older
-** data for a particular docid with newer data, so deletes or updates
-** will eventually overtake the earlier data and knock it out.  The
-** query logic likewise merges doclists so that newer data knocks out
-** older data.

-**
-**      Or, if a phrase contains one or more deferred tokens and one or
-**      more non-deferred tokens, then the expression is advanced to the

-**      words, if the phrase is "A B C", and "B" is deferred, the expression
-**      is advanced to the next row that contains an instance of "A * C", 
-**      where "*" may match any single token. The position list in this case
-**      is populated as for "A * C" before returning.
-**
-**   2. NEAR is treated as AND. If the expression is "x NEAR y", it is 
-**      advanced to point to the next row that matches "x AND y".

-** See sqlite3Fts3EvalTestDeferred() for details on testing if a row is

-** By default, this module parses the legacy syntax that has been 
-** traditionally used by fts3. Or, if SQLITE_ENABLE_FTS3_PARENTHESIS
-** is defined, then it uses the new syntax. The differences between
-** the new and the old syntaxes are:
-**
-**  a) The new syntax supports parenthesis. The old does not.
-**
-**  b) The new syntax supports the AND and NOT operators. The old does not.
-**
-**  c) The old syntax supports the "-" token qualifier. This is not 
-**     supported by the new syntax (it is replaced by the NOT operator).
-**
-**  d) When using the old syntax, the OR operator has a greater precedence
-**     than an implicit AND. When using the new, both implicity and explicit
-**     AND operators have a higher precedence than OR.
-**
-** If compiled with SQLITE_TEST defined, then this module exports the
-** symbol "int sqlite3_fts3_enable_parentheses". Setting this variable
-** to zero causes the module to use the old syntax. If it is set to 
-** non-zero the new syntax is activated. This is so both syntaxes can
-** be tested using a single build of testfixture.
-**
-** The following describes the syntax supported by the fts3 MATCH
-** operator in a similar format to that used by the lemon parser
-** generator. This module does not use actually lemon, it uses a
-** custom parser.
-**
-**   query ::= andexpr (OR andexpr)*.
-**
-**   andexpr ::= notexpr (AND? notexpr)*.
-**
-**   notexpr ::= nearexpr (NOT nearexpr|-TOKEN)*.
-**   notexpr ::= LP query RP.
-**
-**   nearexpr ::= phrase (NEAR distance_opt nearexpr)*.
-**
-**   distance_opt ::= .
-**   distance_opt ::= / INTEGER.
-**
-**   phrase ::= TOKEN.
-**   phrase ::= COLUMN:TOKEN.

-**   Tclcmd: fts3_configure_incr_load ?CHUNKSIZE THRESHOLD?
-**
-** Normally, FTS uses hard-coded values to determine the minimum doclist
-** size eligible for incremental loading, and the size of the chunks loaded
-** when a doclist is incrementally loaded. This command allows the built-in
-** values to be overridden for testing purposes.
-**
-** If present, the first argument is the chunksize in bytes to load doclists
-** in. The second argument is the minimum doclist size in bytes to use
-** incremental loading with.
-**
-** Whether or not the arguments are present, this command returns a list of
-** two integers - the initial chunksize and threshold when the command is
-** invoked. This can be used to restore the default behavior after running
-** tests. For example:
-**
-**    # Override incr-load settings for testing:
-**    set cfg [fts3_configure_incr_load $new_chunksize $new_threshold]
-**
-**    .... run tests ....
-**
-**    # Restore initial incr-load settings:
-**    eval fts3_configure_incr_load $cfg

-** This file contains code for the "fts3tokenize" virtual table module.
-** An fts3tokenize virtual table is created as follows:
-**
-**   CREATE VIRTUAL TABLE <tbl> USING fts3tokenize(

-**   );
-**
-** The table created has the following schema:

-**   CREATE TABLE <tbl>(input, token, start, end, position)
-**
-** When queried, the query must include a WHERE clause of type:
-**
-**   input = <string>
-**
-** The virtual table module tokenizes this <string>, using the FTS3 
-** tokenizer specified by the arguments to the CREATE VIRTUAL TABLE 
-** statement and returns one row for each token in the result. With
-** fields set as follows:
-**
-**   input:   Always set to a copy of <string>
-**   token:   A token from the input.
-**   start:   Byte offset of the token within the input <string>.
-**   end:     Byte offset of the byte immediately following the end of the
-**            token within the input string.
-**   pos:     Token offset of token within input.

-# Case Folding Properties
-#
-# This file is a supplement to the UnicodeData file.
-# It provides a case folding mapping generated from the Unicode Character Database.
-# If all characters are mapped according to the full mapping below, then
-# case differences (according to UnicodeData.txt and SpecialCasing.txt)
-# are eliminated.
-#
-# The data supports both implementations that require simple case foldings
-# (where string lengths don't change), and implementations that allow full case folding
-# (where string lengths may grow). Note that where they can be supported, the
-# full case foldings are superior: for example, they allow "MASSE" and "Maße" to match.
-#
-# All code points not listed in this file map to themselves.
-#
-# NOTE: case folding does not preserve normalization formats!
-#
-# For information on case folding, including how to have case folding 
-# preserve normalization formats, see Section 3.13 Default Case Algorithms in
-# The Unicode Standard, Version 5.0.
-#
-# ================================================================================
-# Format
-# ================================================================================
-# The entries in this file are in the following machine-readable format:
-#
-# <code>; <status>; <mapping>; # <name>
-#
-# The status field is:
-# C: common case folding, common mappings shared by both simple and full mappings.
-# F: full case folding, mappings that cause strings to grow in length. Multiple characters are separated by spaces.
-# S: simple case folding, mappings to single characters where different from F.
-# T: special case for uppercase I and dotted uppercase I
-#    - For non-Turkic languages, this mapping is normally not used.
-#    - For Turkic languages (tr, az), this mapping can be used instead of the normal mapping for these characters.
-#      Note that the Turkic mappings do not maintain canonical equivalence without additional processing.
-#      See the discussions of case mapping in the Unicode Standard for more information.
-#
-# Usage:
-#  A. To do a simple case folding, use the mappings with status C + S.
-#  B. To do a full case folding, use the mappings with status C + F.
-#
-#    The mappings with status T can be used or omitted depending on the desired case-folding
-#    behavior. (The default option is to exclude them.)
-#
-# =================================================================
-
-# Property: Case_Folding
-
-#  All code points not explicitly listed for Case_Folding
-#  have the value C for the status field, and the code point itself for the mapping field.

-** EXTENSION API FUNCTIONS
-**
-** xUserData(pFts):
-**   Return a copy of the context pointer the extension function was 
-**   registered with.
-**
-** xColumnTotalSize(pFts, iCol, pnToken):
-**   If parameter iCol is less than zero, set output variable *pnToken
-**   to the total number of tokens in the FTS5 table. Or, if iCol is
-**   non-negative but less than the number of columns in the table, return
-**   the total number of tokens in column iCol, considering all rows in 
-**   the FTS5 table.
-**
-**   If parameter iCol is greater than or equal to the number of columns
-**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
-**   an OOM condition or IO error), an appropriate SQLite error code is 
-**   returned.
-**
-** xColumnCount(pFts):
-**   Return the number of columns in the table.
-**
-** xColumnSize(pFts, iCol, pnToken):
-**   If parameter iCol is less than zero, set output variable *pnToken
-**   to the total number of tokens in the current row. Or, if iCol is
-**   non-negative but less than the number of columns in the table, set
-**   *pnToken to the number of tokens in column iCol of the current row.
-**
-**   If parameter iCol is greater than or equal to the number of columns
-**   in the table, SQLITE_RANGE is returned. Or, if an error occurs (e.g.
-**   an OOM condition or IO error), an appropriate SQLite error code is 
-**   returned.
-**
-**   This function may be quite inefficient if used with an FTS5 table
-**   created with the "columnsize=0" option.
-**
-** xColumnText:
-**   This function attempts to retrieve the text of column iCol of the
-**   current document. If successful, (*pz) is set to point to a buffer
-**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
-**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
-**   if an error occurs, an SQLite error code is returned and the final values
-**   of (*pz) and (*pn) are undefined.
-**
-** xPhraseCount:
-**   Returns the number of phrases in the current query expression.
-**
-** xPhraseSize:
-**   Returns the number of tokens in phrase iPhrase of the query. Phrases
-**   are numbered starting from zero.
-**
-** xInstCount:
-**   Set *pnInst to the total number of occurrences of all phrases within
-**   the query within the current row. Return SQLITE_OK if successful, or
-**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" or "detail=column" option. If the FTS5 table is created 
-**   with either "detail=none" or "detail=column" and "content=" option 
-**   (i.e. if it is a contentless table), then this API always returns 0.
-**
-** xInst:
-**   Query for the details of phrase match iIdx within the current row.
-**   Phrase matches are numbered starting from zero, so the iIdx argument
-**   should be greater than or equal to zero and smaller than the value
-**   output by xInstCount().
-**
-**   Usually, output parameter *piPhrase is set to the phrase number, *piCol
-**   to the column in which it occurs and *piOff the token offset of the
-**   first token of the phrase. The exception is if the table was created
-**   with the offsets=0 option specified. In this case *piOff is always
-**   set to -1.
-**
-**   Returns SQLITE_OK if successful, or an error code (i.e. SQLITE_NOMEM) 
-**   if an error occurs.
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" or "detail=column" option. 
-**
-** xRowid:
-**   Returns the rowid of the current row.
-**
-** xTokenize:
-**   Tokenize text using the tokenizer belonging to the FTS5 table.
-**
-** xQueryPhrase(pFts5, iPhrase, pUserData, xCallback):
-**   This API function is used to query the FTS table for phrase iPhrase
-**   of the current query. Specifically, a query equivalent to:
-**
-**       ... FROM ftstable WHERE ftstable MATCH $p ORDER BY rowid
-**
-**   with $p set to a phrase equivalent to the phrase iPhrase of the
-**   current query is executed. Any column filter that applies to
-**   phrase iPhrase of the current query is included in $p. For each 
-**   row visited, the callback function passed as the fourth argument 
-**   is invoked. The context and API objects passed to the callback 
-**   function may be used to access the properties of each matched row.
-**   Invoking Api.xUserData() returns a copy of the pointer passed as 
-**   the third argument to pUserData.
-**
-**   If the callback function returns any value other than SQLITE_OK, the
-**   query is abandoned and the xQueryPhrase function returns immediately.
-**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
-**   Otherwise, the error code is propagated upwards.
-**
-**   If the query runs to completion without incident, SQLITE_OK is returned.
-**   Or, if some error occurs before the query completes or is aborted by
-**   the callback, an SQLite error code is returned.
-**
-**
-** xSetAuxdata(pFts5, pAux, xDelete)
-**
-**   Save the pointer passed as the second argument as the extension functions 
-**   "auxiliary data". The pointer may then be retrieved by the current or any
-**   future invocation of the same fts5 extension function made as part of
-**   of the same MATCH query using the xGetAuxdata() API.
-**
-**   Each extension function is allocated a single auxiliary data slot for
-**   each FTS query (MATCH expression). If the extension function is invoked 
-**   more than once for a single FTS query, then all invocations share a 
-**   single auxiliary data context.
-**
-**   If there is already an auxiliary data pointer when this function is
-**   invoked, then it is replaced by the new pointer. If an xDelete callback
-**   was specified along with the original pointer, it is invoked at this
-**   point.
-**
-**   The xDelete callback, if one is specified, is also invoked on the
-**   auxiliary data pointer after the FTS5 query has finished.
-**
-**   If an error (e.g. an OOM condition) occurs within this function, an
-**   the auxiliary data is set to NULL and an error code returned. If the
-**   xDelete parameter was not NULL, it is invoked on the auxiliary data
-**   pointer before returning.
-**
-**
-** xGetAuxdata(pFts5, bClear)
-**
-**   Returns the current auxiliary data pointer for the fts5 extension 
-**   function. See the xSetAuxdata() method for details.
-**
-**   If the bClear argument is non-zero, then the auxiliary data is cleared
-**   (set to NULL) before this function returns. In this case the xDelete,
-**   if any, is not invoked.
-**
-**
-** xRowCount(pFts5, pnRow)
-**
-**   This function is used to retrieve the total number of rows in the table.
-**   In other words, the same value that would be returned by:
-**
-**        SELECT count(*) FROM ftstable;
-**
-** xPhraseFirst()
-**   This function is used, along with type Fts5PhraseIter and the xPhraseNext
-**   method, to iterate through all instances of a single query phrase within
-**   the current row. This is the same information as is accessible via the
-**   xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient
-**   to use, this API may be faster under some circumstances. To iterate 
-**   through instances of phrase iPhrase, use the following code:
-**
-**       Fts5PhraseIter iter;
-**       int iCol, iOff;
-**       for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff);
-**           iCol>=0;
-**           pApi->xPhraseNext(pFts, &iter, &iCol, &iOff)
-**       ){
-**         // An instance of phrase iPhrase at offset iOff of column iCol
-**       }
-**
-**   The Fts5PhraseIter structure is defined above. Applications should not
-**   modify this structure directly - it should only be used as shown above
-**   with the xPhraseFirst() and xPhraseNext() API methods (and by
-**   xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below).
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" or "detail=column" option. If the FTS5 table is created 
-**   with either "detail=none" or "detail=column" and "content=" option 
-**   (i.e. if it is a contentless table), then this API always iterates
-**   through an empty set (all calls to xPhraseFirst() set iCol to -1).
-**
-** xPhraseNext()
-**   See xPhraseFirst above.
-**
-** xPhraseFirstColumn()
-**   This function and xPhraseNextColumn() are similar to the xPhraseFirst()
-**   and xPhraseNext() APIs described above. The difference is that instead
-**   of iterating through all instances of a phrase in the current row, these
-**   APIs are used to iterate through the set of columns in the current row
-**   that contain one or more instances of a specified phrase. For example:
-**
-**       Fts5PhraseIter iter;
-**       int iCol;
-**       for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol);
-**           iCol>=0;
-**           pApi->xPhraseNextColumn(pFts, &iter, &iCol)
-**       ){
-**         // Column iCol contains at least one instance of phrase iPhrase
-**       }
-**
-**   This API can be quite slow if used with an FTS5 table created with the
-**   "detail=none" option. If the FTS5 table is created with either 
-**   "detail=none" "content=" option (i.e. if it is a contentless table), 
-**   then this API always iterates through an empty set (all calls to 
-**   xPhraseFirstColumn() set iCol to -1).
-**
-**   The information accessed using this API and its companion
-**   xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext
-**   (or xInst/xInstCount). The chief advantage of this API is that it is
-**   significantly more efficient than those alternatives when used with
-**   "detail=column" tables.  
-**
-** xPhraseNextColumn()
-**   See xPhraseFirstColumn above.

-** CUSTOM AUXILIARY FUNCTIONS
-*************************************************************************/
-
-/*************************************************************************
-** CUSTOM TOKENIZERS
-**
-** Applications may also register custom tokenizer types. A tokenizer 
-** is registered by providing fts5 with a populated instance of the 
-** following structure. All structure methods must be defined, setting
-** any member of the fts5_tokenizer struct to NULL leads to undefined
-** behaviour. The structure methods are expected to function as follows:
-**
-** xCreate:
-**   This function is used to allocate and initialize a tokenizer instance.
-**   A tokenizer instance is required to actually tokenize text.
-**
-**   The first argument passed to this function is a copy of the (void*)
-**   pointer provided by the application when the fts5_tokenizer object
-**   was registered with FTS5 (the third argument to xCreateTokenizer()). 
-**   The second and third arguments are an array of nul-terminated strings
-**   containing the tokenizer arguments, if any, specified following the
-**   tokenizer name as part of the CREATE VIRTUAL TABLE statement used
-**   to create the FTS5 table.
-**
-**   The final argument is an output variable. If successful, (*ppOut) 
-**   should be set to point to the new tokenizer handle and SQLITE_OK
-**   returned. If an error occurs, some value other than SQLITE_OK should
-**   be returned. In this case, fts5 assumes that the final value of *ppOut 
-**   is undefined.
-**
-** xDelete:
-**   This function is invoked to delete a tokenizer handle previously
-**   allocated using xCreate(). Fts5 guarantees that this function will
-**   be invoked exactly once for each successful call to xCreate().
-**
-** xTokenize:
-**   This function is expected to tokenize the nText byte string indicated 
-**   by argument pText. pText may or may not be nul-terminated. The first
-**   argument passed to this function is a pointer to an Fts5Tokenizer object
-**   returned by an earlier call to xCreate().
-**
-**   The second argument indicates the reason that FTS5 is requesting
-**   tokenization of the supplied text. This is always one of the following
-**   four values:
-**
-**   <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into
-**            or removed from the FTS table. The tokenizer is being invoked to
-**            determine the set of tokens to add to (or delete from) the
-**            FTS index.
-**
-**       <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed 
-**            against the FTS index. The tokenizer is being called to tokenize 
-**            a bareword or quoted string specified as part of the query.
-**
-**       <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as
-**            FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is
-**            followed by a "*" character, indicating that the last token
-**            returned by the tokenizer will be treated as a token prefix.
-**
-**       <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to 
-**            satisfy an fts5_api.xTokenize() request made by an auxiliary
-**            function. Or an fts5_api.xColumnSize() request made by the same
-**            on a columnsize=0 database.  
-**   </ul>
-**
-**   For each token in the input string, the supplied callback xToken() must
-**   be invoked. The first argument to it should be a copy of the pointer
-**   passed as the second argument to xTokenize(). The third and fourth
-**   arguments are a pointer to a buffer containing the token text, and the
-**   size of the token in bytes. The 4th and 5th arguments are the byte offsets
-**   of the first byte of and first byte immediately following the text from
-**   which the token is derived within the input.
-**
-**   The second argument passed to the xToken() callback ("tflags") should
-**   normally be set to 0. The exception is if the tokenizer supports 
-**   synonyms. In this case see the discussion below for details.
-**
-**   FTS5 assumes the xToken() callback is invoked for each token in the 
-**   order that they occur within the input text.
-**
-**   If an xToken() callback returns any value other than SQLITE_OK, then
-**   the tokenization should be abandoned and the xTokenize() method should
-**   immediately return a copy of the xToken() return value. Or, if the
-**   input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally,
-**   if an error occurs with the xTokenize() implementation itself, it
-**   may abandon the tokenization and return any error code other than
-**   SQLITE_OK or SQLITE_DONE.
-**
-** SYNONYM SUPPORT
-**
-**   Custom tokenizers may also support synonyms. Consider a case in which a
-**   user wishes to query for a phrase such as "first place". Using the 
-**   built-in tokenizers, the FTS5 query 'first + place' will match instances
-**   of "first place" within the document set, but not alternative forms
-**   such as "1st place". In some applications, it would be better to match
-**   all instances of "first place" or "1st place" regardless of which form
-**   the user specified in the MATCH query text.
-**
-**   There are several ways to approach this in FTS5:
-**
-**   <ol><li> By mapping all synonyms to a single token. In this case, the 
-**            In the above example, this means that the tokenizer returns the
-**            same token for inputs "first" and "1st". Say that token is in
-**            fact "first", so that when the user inserts the document "I won
-**            1st place" entries are added to the index for tokens "i", "won",
-**            "first" and "place". If the user then queries for '1st + place',
-**            the tokenizer substitutes "first" for "1st" and the query works
-**            as expected.
-**
-**       <li> By adding multiple synonyms for a single term to the FTS index.
-**            In this case, when tokenizing query text, the tokenizer may 
-**            provide multiple synonyms for a single term within the document.
-**            FTS5 then queries the index for each synonym individually. For
-**            example, faced with the query:
-**
-**   <codeblock>
-**     ... MATCH 'first place'</codeblock>
-**
-**            the tokenizer offers both "1st" and "first" as synonyms for the
-**            first token in the MATCH query and FTS5 effectively runs a query 
-**            similar to:
-**
-**   <codeblock>
-**     ... MATCH '(first OR 1st) place'</codeblock>
-**
-**            except that, for the purposes of auxiliary functions, the query
-**            still appears to contain just two phrases - "(first OR 1st)" 
-**            being treated as a single phrase.
-**
-**       <li> By adding multiple synonyms for a single term to the FTS index.
-**            Using this method, when tokenizing document text, the tokenizer
-**            provides multiple synonyms for each token. So that when a 
-**            document such as "I won first place" is tokenized, entries are
-**            added to the FTS index for "i", "won", "first", "1st" and
-**            "place".
-**
-**            This way, even if the tokenizer does not provide synonyms
-**            when tokenizing query text (it should not - to do would be
-**            inefficient), it doesn't matter if the user queries for 
-**            'first + place' or '1st + place', as there are entires in the
-**            FTS index corresponding to both forms of the first token.
-**   </ol>
-**
-**   Whether it is parsing document or query text, any call to xToken that
-**   specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit
-**   is considered to supply a synonym for the previous token. For example,
-**   when parsing the document "I won first place", a tokenizer that supports
-**   synonyms would call xToken() 5 times, as follows:
-**
-**   <codeblock>
-**       xToken(pCtx, 0, "i",                      1,  0,  1);
-**       xToken(pCtx, 0, "won",                    3,  2,  5);
-**       xToken(pCtx, 0, "first",                  5,  6, 11);
-**       xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3,  6, 11);
-**       xToken(pCtx, 0, "place",                  5, 12, 17);
-**</codeblock>
-**
-**   It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time
-**   xToken() is called. Multiple synonyms may be specified for a single token
-**   by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence. 
-**   There is no limit to the number of synonyms that may be provided for a
-**   single token.
-**
-**   In many cases, method (1) above is the best approach. It does not add 
-**   extra data to the FTS index or require FTS5 to query for multiple terms,
-**   so it is efficient in terms of disk space and query speed. However, it
-**   does not support prefix queries very well. If, as suggested above, the
-**   token "first" is subsituted for "1st" by the tokenizer, then the query:
-**
-**   <codeblock>
-**     ... MATCH '1s*'</codeblock>
-**
-**   will not match documents that contain the token "1st" (as the tokenizer
-**   will probably not map "1s" to any prefix of "first").
-**
-**   For full prefix support, method (3) may be preferred. In this case, 
-**   because the index contains entries for both "first" and "1st", prefix
-**   queries such as 'fi*' or '1s*' will match correctly. However, because
-**   extra entries are added to the FTS index, this method uses more space
-**   within the database.
-**
-**   Method (2) offers a midpoint between (1) and (3). Using this method,
-**   a query such as '1s*' will match documents that contain the literal 
-**   token "1st", but not "first" (assuming the tokenizer is not able to
-**   provide synonyms for prefixes). However, a non-prefix query like '1st'
-**   will match against "1st" and "first". This method does not require
-**   extra disk space, as no extra entries are added to the FTS index. 
-**   On the other hand, it may require more CPU cycles to run MATCH queries,
-**   as separate queries of the FTS index are required for each synonym.
-**
-**   When using methods (2) or (3), it is important that the tokenizer only
-**   provide synonyms when tokenizing document text (method (2)) or query
-**   text (method (3)), not both. Doing so will not cause any errors, but is
-**   inefficient.

-/*
-** Details:
-**
-** The %_data table managed by this module,
-**
-**     CREATE TABLE %_data(id INTEGER PRIMARY KEY, block BLOB);
-**
-** , contains the following 5 types of records. See the comments surrounding
-** the FTS5_*_ROWID macros below for a description of how %_data rowids are 
-** assigned to each fo them.
-**
-** 1. Structure Records:
-**
-**   The set of segments that make up an index - the index structure - are
-**   recorded in a single record within the %_data table. The record consists
-**   of a single 32-bit configuration cookie value followed by a list of 
-**   SQLite varints. If the FTS table features more than one index (because
-**   there are one or more prefix indexes), it is guaranteed that all share
-**   the same cookie value.
-**
-**   Immediately following the configuration cookie, the record begins with
-**   three varints:
-**
-**     + number of levels,
-**     + total number of segments on all levels,
-**     + value of write counter.
-**
-**   Then, for each level from 0 to nMax:
-**
-**     + number of input segments in ongoing merge.
-**     + total number of segments in level.
-**     + for each segment from oldest to newest:
-**         + segment id (always > 0)
-**         + first leaf page number (often 1, always greater than 0)
-**         + final leaf page number
-**
-** 2. The Averages Record:
-**
-**   A single record within the %_data table. The data is a list of varints.
-**   The first value is the number of rows in the index. Then, for each column
-**   from left to right, the total number of tokens in the column for all
-**   rows of the table.
-**
-** 3. Segment leaves:
-**
-**   TERM/DOCLIST FORMAT:
-**
-**     Most of each segment leaf is taken up by term/doclist data. The 
-**     general format of term/doclist, starting with the first term
-**     on the leaf page, is:
-**
-**         varint : size of first term
-**         blob:    first term data
-**         doclist: first doclist
-**         zero-or-more {
-**           varint:  number of bytes in common with previous term
-**           varint:  number of bytes of new term data (nNew)
-**           blob:    nNew bytes of new term data
-**           doclist: next doclist
-**         }
-**
-**     doclist format:
-**
-**         varint:  first rowid
-**         poslist: first poslist
-**         zero-or-more {
-**           varint:  rowid delta (always > 0)
-**           poslist: next poslist
-**         }
-**
-**     poslist format:
-**
-**         varint: size of poslist in bytes multiplied by 2, not including
-**                 this field. Plus 1 if this entry carries the "delete" flag.
-**         collist: collist for column 0
-**         zero-or-more {
-**           0x01 byte
-**           varint: column number (I)
-**           collist: collist for column I
-**         }
-**
-**     collist format:
-**
-**         varint: first offset + 2
-**         zero-or-more {
-**           varint: offset delta + 2
-**         }
-**
-**   PAGE FORMAT
-**
-**     Each leaf page begins with a 4-byte header containing 2 16-bit 
-**     unsigned integer fields in big-endian format. They are:
-**
-**       * The byte offset of the first rowid on the page, if it exists
-**         and occurs before the first term (otherwise 0).
-**
-**       * The byte offset of the start of the page footer. If the page
-**         footer is 0 bytes in size, then this field is the same as the
-**         size of the leaf page in bytes.
-**
-**     The page footer consists of a single varint for each term located
-**     on the page. Each varint is the byte offset of the current term
-**     within the page, delta-compressed against the previous value. In
-**     other words, the first varint in the footer is the byte offset of
-**     the first term, the second is the byte offset of the second less that
-**     of the first, and so on.
-**
-**     The term/doclist format described above is accurate if the entire
-**     term/doclist data fits on a single leaf page. If this is not the case,
-**     the format is changed in two ways:
-**
-**       + if the first rowid on a page occurs before the first term, it
-**         is stored as a literal value:
-**
-**             varint:  first rowid
-**
-**       + the first term on each page is stored in the same way as the
-**         very first term of the segment:
-**
-**             varint : size of first term
-**             blob:    first term data
-**
-** 5. Segment doclist indexes:
-**
-**   Doclist indexes are themselves b-trees, however they usually consist of
-**   a single leaf record only. The format of each doclist index leaf page 
-**   is:
-**
-**     * Flags byte. Bits are:
-**         0x01: Clear if leaf is also the root page, otherwise set.
-**
-**     * Page number of fts index leaf page. As a varint.
-**
-**     * First rowid on page indicated by previous field. As a varint.
-**
-**     * A list of varints, one for each subsequent termless page. A 
-**       positive delta if the termless page contains at least one rowid, 
-**       or an 0x00 byte otherwise.
-**
-**   Internal doclist index nodes are:
-**
-**     * Flags byte. Bits are:
-**         0x01: Clear for root page, otherwise set.
-**
-**     * Page number of first child page. As a varint.
-**
-**     * Copy of first rowid on page indicated by previous field. As a varint.
-**
-**     * A list of delta-encoded varints - the first rowid on each subsequent
-**       child page.

-** NOTES ON TRANSACTIONS: 
-**
-** SQLite invokes the following virtual table methods as transactions are 
-** opened and closed by the user:
-**
-**     xBegin():    Start of a new transaction.
-**     xSync():     Initial part of two-phase commit.
-**     xCommit():   Final part of two-phase commit.
-**     xRollback(): Rollback the transaction.
-**
-** Anything that is required as part of a commit that may fail is performed
-** in the xSync() callback. Current versions of SQLite ignore any errors 
-** returned by xCommit().
-**
-** And as sub-transactions are opened/closed:
-**
-**     xSavepoint(int S):  Open savepoint S.
-**     xRelease(int S):    Commit and close savepoint S.
-**     xRollbackTo(int S): Rollback to start of savepoint S.
-**
-** During a write-transaction the fts5_index.c module may cache some data 
-** in-memory. It is flushed to disk whenever xSync(), xRelease() or
-** xSavepoint() is called. And discarded whenever xRollback() or xRollbackTo() 
-** is called.
-**
-** Additionally, if SQLITE_DEBUG is defined, an instance of the following
-** structure is used to record the current transaction state. This information
-** is not required, but it is used in the assert() statements executed by
-** function fts5CheckTransactionState() (see below).

-**
-** This file contains test code only, it is not included in release 
-** versions of FTS5. It contains the implementation of an FTS5 auxiliary
-** function very similar to the FTS4 function matchinfo():
-**
-**     https://www.sqlite.org/fts3.html#matchinfo
-**
-** Known differences are that:
-**
-**  1) this function uses the FTS5 definition of "matchable phrase", which
-**     excludes any phrases that are part of an expression sub-tree that
-**     does not match the current row. This comes up for MATCH queries 
-**     such as:
-**
-**         "a OR (b AND c)"
-**
-**     In FTS4, if a single row contains instances of tokens "a" and "c", 
-**     but not "b", all instances of "c" are considered matches. In FTS5,
-**     they are not (as the "b AND c" sub-tree does not match the current
-**     row.
-**
-**  2) For the values returned by 'x' that apply to all rows of the table, 
-**     NEAR constraints are not considered. But for the number of hits in
-**     the current row, they are.
-**     
-** This file exports a single function that may be called to register the
-** matchinfo() implementation with a database handle:
-**
-**   int sqlite3Fts5TestRegisterMatchinfo(sqlite3 *db);

-******************************************************************************
-**
-** This file contains code for the "fts5tokenize" virtual table module.
-** An fts5tokenize virtual table is created as follows:
-**
-**   CREATE VIRTUAL TABLE <tbl> USING fts5tokenize(
-**       <tokenizer-name>, <arg-1>, ...
-**   );
-**
-** The table created has the following schema:
-**
-**   CREATE TABLE <tbl>(input HIDDEN, token, start, end, position)
-**
-** When queried, the query must include a WHERE clause of type:
-**
-**   input = <string>
-**
-** The virtual table module tokenizes this <string>, using the FTS3 
-** tokenizer specified by the arguments to the CREATE VIRTUAL TABLE 
-** statement and returns one row for each token in the result. With
-** fields set as follows:
-**
-**   input:   Always set to a copy of <string>
-**   token:   A token from the input.
-**   start:   Byte offset of the token within the input <string>.
-**   end:     Byte offset of the byte immediately following the end of the
-**            token within the input string.
-**   pos:     Token offset of token within input.

-** tables:
-**
-** col:
-**     CREATE TABLE vocab(term, col, doc, cnt, PRIMARY KEY(term, col));
-**
-**   One row for each term/column combination. The value of $doc is set to
-**   the number of fts5 rows that contain at least one instance of term
-**   $term within column $col. Field $cnt is set to the total number of 
-**   instances of term $term in column $col (in any row of the fts5 table). 
-**
-** row:
-**     CREATE TABLE vocab(term, doc, cnt, PRIMARY KEY(term));
-**
-**   One row for each term in the database. The value of $doc is set to
-**   the number of fts5 rows that contain at least one instance of term
-**   $term. Field $cnt is set to the total number of instances of term 
-**   $term in the database.
-**
-** instance:
-**     CREATE TABLE vocab(term, doc, col, offset, PRIMARY KEY(<all-fields>));
-**
-**   One row for each term instance in the database.

-  This script is designed to create fts4/5 tables with more than one column.
-  The -colsize option should be set to a Tcl list of integer values, one for
-  each column in the table. Each value is the number of tokens that will be
-  inserted into the column value for each row. For example, setting the -colsize
-  option to "5 10" creates an FTS table with 2 columns, with roughly 5 and 10
-  tokens per row in each, respectively.
-  
-  Each "FILE" argument should be a text file. The contents of these text files
-  is split on whitespace characters to form a list of tokens. The first N1
-  tokens are used for the first column of the first row, where N1 is the first
-  element of the -colsize list. The next N2 are used for the second column of
-  the first row, and so on. Rows are added to the table until the entire list
-  of tokens is exhausted.

-        1.2  Unicode Aware LIKE Operator
-        1.3  ICU Collation Sequences

-    2. Compilation and Usage
-    
-    3. Bugs, Problems and Security Issues
-    
-        3.1  The "case_sensitive_like" Pragma
-        3.2  The SQLITE_MAX_LIKE_PATTERN_LENGTH Macro
-        3.3  Collation Sequence Security Issue
-
-
-1. FEATURES
-
-  1.1  SQL Scalars upper() and lower()
-
-    SQLite's built-in implementations of these two functions only 
-    provide case mapping for the 26 letters used in the English
-    language. The ICU based functions provided by this extension
-    provide case mapping, where defined, for the full range of 
-    unicode characters.
-
-    ICU provides two types of case mapping, "general" case mapping and
-    "language specific". Refer to ICU documentation for the differences
-    between the two. Specifically:
-
-       http://www.icu-project.org/userguide/caseMappings.html
-       http://www.icu-project.org/userguide/posix.html#case_mappings
-
-    To utilise "general" case mapping, the upper() or lower() scalar 
-    functions are invoked with one argument:
-
-        upper('abc') -> 'ABC'
-        lower('ABC') -> 'abc'
-
-    To access ICU "language specific" case mapping, upper() or lower()
-    should be invoked with two arguments. The second argument is the name
-    of the locale to use. Passing an empty string ("") or SQL NULL value
-    as the second argument is the same as invoking the 1 argument version
-    of upper() or lower():
-
-        lower('I', 'en_us') -> 'i'
-        lower('I', 'tr_tr') -> 'ı' (small dotless i)
-
-  1.2  Unicode Aware LIKE Operator
-
-    Similarly to the upper() and lower() functions, the built-in SQLite LIKE
-    operator understands case equivalence for the 26 letters of the English
-    language alphabet. The implementation of LIKE included in this
-    extension uses the ICU function u_foldCase() to provide case
-    independent comparisons for the full range of unicode characters.  
-
-    The U_FOLD_CASE_DEFAULT flag is passed to u_foldCase(), meaning the
-    dotless 'I' character used in the Turkish language is considered
-    to be in the same equivalence class as the dotted 'I' character
-    used by many languages (including English).
-
-  1.3  ICU Collation Sequences
-
-    A special SQL scalar function, icu_load_collation() is provided that 
-    may be used to register ICU collation sequences with SQLite. It
-    is always called with exactly two arguments, the ICU locale 
-    identifying the collation sequence to ICU, and the name of the
-    SQLite collation sequence to create. For example, to create an
-    SQLite collation sequence named "turkish" using Turkish language
-    sorting rules, the SQL statement:
-
-        SELECT icu_load_collation('tr_TR', 'turkish');
-
-    Or, for Australian English:
-
-        SELECT icu_load_collation('en_AU', 'australian');
-
-    The identifiers "turkish" and "australian" may then be used
-    as collation sequence identifiers in SQL statements:
-
-        CREATE TABLE aust_turkish_penpals(
-          australian_penpal_name TEXT COLLATE australian,
-          turkish_penpal_name    TEXT COLLATE turkish
-        );
-  
-  1.4 SQL REGEXP Operator
-
-    This extension provides an implementation of the SQL binary
-    comparision operator "REGEXP", based on the regular expression functions
-    provided by the ICU library. The syntax of the operator is as described
-    in SQLite documentation:
-
-        <string> REGEXP <re-pattern>
-
-    This extension uses the ICU defaults for regular expression matching
-    behavior. Specifically, this means that:
-
-        * Matching is case-sensitive,
-        * Regular expression comments are not allowed within patterns, and
-        * The '^' and '$' characters match the beginning and end of the
-          <string> argument, not the beginning and end of lines within
-          the <string> argument.
-
-    Even more specifically, the value passed to the "flags" parameter
-    of ICU C function uregex_open() is 0.
-
-
-2  COMPILATION AND USAGE
-
-  The easiest way to compile and use the ICU extension is to build
-  and use it as a dynamically loadable SQLite extension. To do this
-  using gcc on *nix:
-
-    gcc -shared icu.c `icu-config --ldflags` -o libSqliteIcu.so
-
-  You may need to add "-I" flags so that gcc can find sqlite3ext.h
-  and sqlite3.h. The resulting shared lib, libSqliteIcu.so, may be
-  loaded into sqlite in the same way as any other dynamically loadable
-  extension.
-
-
-3 BUGS, PROBLEMS AND SECURITY ISSUES
-
-  3.1 The "case_sensitive_like" Pragma
-
-    This extension does not work well with the "case_sensitive_like"
-    pragma. If this pragma is used before the ICU extension is loaded,
-    then the pragma has no effect. If the pragma is used after the ICU
-    extension is loaded, then SQLite ignores the ICU implementation and
-    always uses the built-in LIKE operator.
-
-    The ICU extension LIKE operator is always case insensitive.
-
-  3.2 The SQLITE_MAX_LIKE_PATTERN_LENGTH Macro
-
-    Passing very long patterns to the built-in SQLite LIKE operator can
-    cause excessive CPU usage. To curb this problem, SQLite defines the
-    SQLITE_MAX_LIKE_PATTERN_LENGTH macro as the maximum length of a
-    pattern in bytes (irrespective of encoding). The default value is
-    defined in internal header file "limits.h".
-    
-    The ICU extension LIKE implementation suffers from the same 
-    problem and uses the same solution. However, since the ICU extension
-    code does not include the SQLite file "limits.h", modifying
-    the default value therein does not affect the ICU extension.
-    The default value of SQLITE_MAX_LIKE_PATTERN_LENGTH used by
-    the ICU extension LIKE operator is 50000, defined in source 
-    file "icu.c".
-
-  3.3 Collation Sequence Security Issue
-
-    Internally, SQLite assumes that indices stored in database files
-    are sorted according to the collation sequence indicated by the
-    SQL schema. Changing the definition of a collation sequence after
-    an index has been built is therefore equivalent to database
-    corruption. The SQLite library is not very well tested under
-    these conditions, and may contain potential buffer overruns
-    or other programming errors that could be exploited by a malicious
-    programmer.
-
-    If the ICU extension is used in an environment where potentially
-    malicious users may execute arbitrary SQL (i.e. gears), they
-    should be prevented from invoking the icu_load_collation() function,
-    possibly using the authorisation callback.

-Organization of test case files:
-
-  lsmtest1.c: Data tests. Tests that perform many inserts and deletes on a 
-              database file, then verify that the contents of the database can
-              be queried.
-
-  lsmtest2.c: Crash tests. Tests that attempt to verify that the database 
-              recovers correctly following an application or system crash.
-
-  lsmtest3.c: Rollback tests. Tests that focus on the explicit rollback of
-              transactions and sub-transactions.
-
-  lsmtest4.c: Multi-client tests.
-
-  lsmtest5.c: Multi-client tests with a different thread for each client.
-
-  lsmtest6.c: OOM injection tests.
-
-  lsmtest7.c: API tests.
-
-  lsmtest8.c: Writer crash tests. Tests in this file attempt to verify that
-              the system recovers and other clients proceed unaffected if
-              a process fails in the middle of a write transaction.
-
-              The difference from lsmtest2.c is that this file tests
-              live-recovery (recovery from a failure that occurs while other
-              clients are still running) whereas lsmtest2.c tests recovery
-              from a system or power failure.
-
-  lsmtest9.c: More data tests. These focus on testing that calling
-              lsm_work(nMerge=1) to compact the database does not corrupt it.
-              In other words, that databases containing block-redirects
-              can be read and written.

-** A lookup test consists of selecting a key from the domain and querying
-** pDb for it. The test fails if the presence of the key and, if present,
-** the associated value do not match the expectations defined above.
-**
-** A scan test involves selecting a key from the domain and running
-** the following queries:
-**
-**   1. Scan all keys equal to or greater than the key, in ascending order.
-**   2. Scan all keys equal to or smaller than the key, in descending order.
-**
-** Additionally, if nLookupTest is greater than zero, the following are
-** run once:
-**
-**   1. Scan all keys in the db, in ascending order.
-**   2. Scan all keys in the db, in descending order.
-**
-** As you would assume, the test fails if the returned values do not match
-** expectations.

-**
-** This test case uses one writer and $nReader readers. All connections
-** are driven by a single thread. All connections are opened at the start
-** of the test and remain open until the test is finished.
-**
-** The test consists of $nStep steps. Each step the following is performed:
-**
-**   1. The writer inserts $nWriteStep records into the db.
-**
-**   2. The writer checks that the contents of the db are as expected.
-**
-**   3. Each reader that currently has an open read transaction also checks
-**      that the contents of the db are as expected (according to the snapshot
-**      the read transaction is reading - see below).
-**
-** After step 1, reader 1 opens a read transaction. After step 2, reader
-** 2 opens a read transaction, and so on. At step ($nReader+1), reader 1
-** closes the current read transaction and opens a new one. And so on.
-** The result is that at step N (for N > $nReader), there exists a reader
-** with an open read transaction reading the snapshot committed following
-** steps (N-$nReader-1) to N.

-/*************************************************************************
-** DATABASE CONTENTS:
-**
-**   The database contains up to N key/value pairs, where N is some large 
-**   number (say 10,000,000). Keys are integer values between 0 and (N-1).
-**   The value associated with each key is a pseudo-random blob of data.
-**
-**   Key/value pair keys are encoded as the two bytes "k." followed by a 
-**   10-digit decimal number. i.e. key 45 -> "k.0000000045".
-**
-**   As well as the key/value pairs, the database also contains checksum 
-**   entries. The checksums form a hierarchy - for every F key/value
-**   entries there is one level 1 checksum. And for each F level 1 checksums
-**   there is one level 2 checksum. And so on.
-**
-**   Checksum keys are encoded as the two byte "c." followed by the 
-**   checksum level, followed by a 10 digit decimal number containing
-**   the value of the first key that contributes to the checksum value.
-**   For example, assuming F==10, the level 1 checksum that spans keys
-**   10 to 19 is "c.1.0000000010".
-**
-**   Clients may perform one of two operations on the database: a read
-**   or a write.
-** 
-** READ OPERATIONS:
-**
-**   A read operation scans a range of F key/value pairs. It computes
-**   the expected checksum and then compares the computed value to the
-**   actual value stored in the level 1 checksum entry. It then scans 
-**   the group of F level 1 checksums, and compares the computed checksum 
-**   to the associated level 2 checksum value, and so on until the 
-**   highest level checksum value has been verified.
-**
-**   If a checksum ever fails to match the expected value, the test 
-**   has failed.
-**
-** WRITE OPERATIONS:
-**
-**   A write operation involves writing (possibly clobbering) a single
-**   key/value pair. The associated level 1 checksum is then recalculated
-**   updated. Then the level 2 checksum, and so on until the highest
-**   level checksum has been modified.
-**
-**   All updates occur inside a single transaction.
-**
-** INTERFACE:
-**
-**   The interface used by test cases to read and write the db consists
-**   of type DbParameters and the following functions:
-**
-**       dbReadOperation()
-**       dbWriteOperation()

-** SUMMARY
-**
-**   This file implements the 'io' subcommand of the test program. It is used
-**   for testing the performance of various combinations of write() and fsync()
-**   system calls. All operations occur on a single file, which may or may not
-**   exist when a test is started.
-**
-**   A test consists of a series of commands. Each command is either a write
-**   or an fsync. A write is specified as "<amount>@<offset>", where <amount>
-**   is the amount of data written, and <offset> is the offset of the file
-**   to write to. An <amount> or an <offset> is specified as an integer number
-**   of bytes. Or, if postfixed with a "K", "M" or "G", an integer number of
-**   KB, MB or GB, respectively. An fsync is simply "S". All commands are
-**   case-insensitive.
-**
-**   Example test program:
-**
-**        2M@6M 1492K@4M S 4096@4K S
-**
-**   This program writes 2 MB of data starting at the offset 6MB offset of
-**   the file, followed by 1492 KB of data written at the 4MB offset of the
-**   file, followed by a call to fsync(), a write of 4KB of data at byte
-**   offset 4096, and finally another call to fsync().
-**
-**   Commands may either be specified on the command line (one command per
-**   command line argument) or read from stdin. Commands read from stdin
-**   must be separated by white-space.
-**
-** COMMAND LINE INVOCATION
-**
-**   The sub-command implemented in this file must be invoked with at least
-**   two arguments - the path to the file to write to and the page-size to
-**   use for writing. If there are more than two arguments, then each
-**   subsequent argument is assumed to be a test command. If there are exactly
-**   two arguments, the test commands are read from stdin.
-**
-**   A write command does not result in a single call to system call write().
-**   Instead, the specified region is written sequentially using one or
-**   more calls to write(), each of which writes not more than one page of
-**   data. For example, if the page-size is 4KB, the command "2M@6M" results
-**   in 512 calls to write(), each of which writes 4KB of data.
-**
-** EXAMPLES
-**
-**   Two equivalent examples:
-**
-**     $ lsmtest io testfile.db 4KB 2M@6M 1492K@4M S 4096@4K S
-**     3544K written in 129 ms
-**     $ echo "2M@6M 1492K@4M S 4096@4K S" | lsmtest io testfile.db 4096 
-**     3544K written in 127 ms

-** These functions and the iLevel parameter follow the same conventions as
-** the SQLite 4 transaction interface. Note that this is slightly different
-** from the way LSM does things. As follows:
-**
-** tdb_begin():
-**   A successful call to tdb_begin() with (iLevel>1) guarantees that 
-**   there are at least (iLevel-1) write transactions open. If iLevel==1,
-**   then it guarantees that at least a read-transaction is open. Calling
-**   tdb_begin() with iLevel==0 is a no-op.
-**
-** tdb_commit():
-**   A successful call to tdb_commit() with (iLevel>1) guarantees that 
-**   there are at most (iLevel-1) write transactions open. If iLevel==1,
-**   then it guarantees that there are no write transactions open (although
-**   a read-transaction may remain open).  Calling tdb_commit() with 
-**   iLevel==0 ensures that all transactions, read or write, have been 
-**   closed and committed.
-**
-** tdb_rollback():
-**   This call is similar to tdb_commit(), except that instead of committing
-**   transactions, it reverts them. For example, calling tdb_rollback() with
-**   iLevel==2 ensures that there is at most one write transaction open, and
-**   restores the database to the state that it was in when that transaction
-**   was opened.
-**
-**   In other words, tdb_commit() just closes transactions - tdb_rollback()
-**   closes transactions and then restores the database to the state it
-**   was in before those transactions were even opened.

-/*
-** The following values may be passed as the second argument to lsm_config().
-**
-** LSM_CONFIG_AUTOFLUSH:
-**   A read/write integer parameter. 
-**
-**   This value determines the amount of data allowed to accumulate in a
-**   live in-memory tree before it is marked as old. After committing a
-**   transaction, a connection checks if the size of the live in-memory tree,
-**   including data structure overhead, is greater than the value of this
-**   option in KB. If it is, and there is not already an old in-memory tree,
-**   the live in-memory tree is marked as old.
-**
-**   The maximum allowable value is 1048576 (1GB). There is no minimum 
-**   value. If this parameter is set to zero, then an attempt is made to
-**   mark the live in-memory tree as old after each transaction is committed.
-**
-**   The default value is 1024 (1MB).
-**
-** LSM_CONFIG_PAGE_SIZE:
-**   A read/write integer parameter. This parameter may only be set before
-**   lsm_open() has been called.
-**
-** LSM_CONFIG_BLOCK_SIZE:
-**   A read/write integer parameter. 
-**
-**   This parameter may only be set before lsm_open() has been called. It
-**   must be set to a power of two between 64 and 65536, inclusive (block 
-**   sizes between 64KB and 64MB).
-**
-**   If the connection creates a new database, the block size of the new
-**   database is set to the value of this option in KB. After lsm_open()
-**   has been called, querying this parameter returns the actual block
-**   size of the opened database.
-**
-**   The default value is 1024 (1MB blocks).
-**
-** LSM_CONFIG_SAFETY:
-**   A read/write integer parameter. Valid values are 0, 1 (the default) 
-**   and 2. This parameter determines how robust the database is in the
-**   face of a system crash (e.g. a power failure or operating system 
-**   crash). As follows:
-**
-**     0 (off):    No robustness. A system crash may corrupt the database.
-**
-**     1 (normal): Some robustness. A system crash may not corrupt the
-**                 database file, but recently committed transactions may
-**                 be lost following recovery.
-**
-**     2 (full):   Full robustness. A system crash may not corrupt the
-**                 database file. Following recovery the database file
-**                 contains all successfully committed transactions.
-**
-** LSM_CONFIG_AUTOWORK:
-**   A read/write integer parameter.
-**
-** LSM_CONFIG_AUTOCHECKPOINT:
-**   A read/write integer parameter.
-**
-**   If this option is set to non-zero value N, then a checkpoint is
-**   automatically attempted after each N KB of data have been written to 
-**   the database file.
-**
-**   The amount of uncheckpointed data already written to the database file
-**   is a global parameter. After performing database work (writing to the
-**   database file), the process checks if the total amount of uncheckpointed 
-**   data exceeds the value of this paramter. If so, a checkpoint is performed.
-**   This means that this option may cause the connection to perform a 
-**   checkpoint even if the current connection has itself written very little
-**   data into the database file.
-**
-**   The default value is 2048 (checkpoint every 2MB).
-**
-** LSM_CONFIG_MMAP:
-**   A read/write integer parameter. If this value is set to 0, then the 
-**   database file is accessed using ordinary read/write IO functions. Or,
-**   if it is set to 1, then the database file is memory mapped and accessed
-**   that way. If this parameter is set to any value N greater than 1, then
-**   up to the first N KB of the file are memory mapped, and any remainder
-**   accessed using read/write IO.
-**
-**   The default value is 1 on 64-bit platforms and 32768 on 32-bit platforms.
-**   
-**
-** LSM_CONFIG_USE_LOG:
-**   A read/write boolean parameter. True (the default) to use the log
-**   file normally. False otherwise.
-**
-** LSM_CONFIG_AUTOMERGE:
-**   A read/write integer parameter. The minimum number of segments to
-**   merge together at a time. Default value 4.
-**
-** LSM_CONFIG_MAX_FREELIST:
-**   A read/write integer parameter. The maximum number of free-list 
-**   entries that are stored in a database checkpoint (the others are
-**   stored elsewhere in the database).
-**
-**   There is no reason for an application to configure or query this
-**   parameter. It is only present because configuring a small value
-**   makes certain parts of the lsm code easier to test.
-**
-** LSM_CONFIG_MULTIPLE_PROCESSES:
-**   A read/write boolean parameter. This parameter may only be set before

-**
-** LSM_INFO_NWRITE:
-**   The third parameter should be of type (int *). The location pointed
-**   to by the third parameter is set to the number of 4KB pages written to
-**   the database file during the lifetime of this connection. 
-**
-** LSM_INFO_NREAD:
-**   The third parameter should be of type (int *). The location pointed
-**   to by the third parameter is set to the number of 4KB pages read from
-**   the database file during the lifetime of this connection.
-**
-** LSM_INFO_DB_STRUCTURE:
-**   The third argument should be of type (char **). The location pointed
-**   to is populated with a pointer to a nul-terminated string containing
-**   the string representation of a Tcl data-structure reflecting the 
-**   current structure of the database file. Specifically, the current state
-**   of the worker snapshot. The returned string should be eventually freed 
-**   by the caller using lsm_free().
-**
-**   The returned list contains one element for each level in the database,
-**   in order from most to least recent. Each element contains a 
-**   single element for each segment comprising the corresponding level,
-**   starting with the lhs segment, then each of the rhs segments (if any)
-**   in order from most to least recent.
-**
-**   Each segment element is itself a list of 4 integer values, as follows:
-**
-**   <ol><li> First page of segment
-**       <li> Last page of segment
-**       <li> Root page of segment (if applicable)
-**       <li> Total number of pages in segment
-**   </ol>
-**
-** LSM_INFO_ARRAY_STRUCTURE:
-**   There should be two arguments passed following this option (i.e. a 
-**   total of four arguments passed to lsm_info()). The first argument 
-**   should be the page number of the first page in a database array 
-**   (perhaps obtained from an earlier INFO_DB_STRUCTURE call). The second 
-**   trailing argument should be of type (char **). The location pointed 
-**   to is populated with a pointer to a nul-terminated string that must 
-**   be eventually freed using lsm_free() by the caller.
-**
-**   The output string contains the text representation of a Tcl list of
-**   integers. Each pair of integers represent a range of pages used by
-**   the identified array. For example, if the array occupies database
-**   pages 993 to 1024, then pages 2048 to 2777, then the returned string
-**   will be "993 1024 2048 2777".
-**
-**   If the specified integer argument does not correspond to the first
-**   page of any database array, LSM_ERROR is returned and the output
-**   pointer is set to a NULL value.
-**
-** LSM_INFO_LOG_STRUCTURE:
-**   The third argument should be of type (char **). The location pointed
-**   to is populated with a pointer to a nul-terminated string containing
-**   the string representation of a Tcl data-structure. The returned 
-**   string should be eventually freed by the caller using lsm_free().
-**
-**   The Tcl structure returned is a list of six integers that describe
-**   the current structure of the log file.
-**
-** LSM_INFO_ARRAY_PAGES:
-**
-** LSM_INFO_PAGE_ASCII_DUMP:
-**   As with LSM_INFO_ARRAY_STRUCTURE, there should be two arguments passed
-**   with calls that specify this option - an integer page number and a
-**   (char **) used to return a nul-terminated string that must be later
-**   freed using lsm_free(). In this case the output string is populated
-**   with a human-readable description of the page content.
-**
-**   If the page cannot be decoded, it is not an error. In this case the
-**   human-readable output message will report the systems failure to 
-**   interpret the page data.
-**
-** LSM_INFO_PAGE_HEX_DUMP:
-**   This argument is similar to PAGE_ASCII_DUMP, except that keys and
-**   values are represented using hexadecimal notation instead of ascii.
-**
-** LSM_INFO_FREELIST:
-**   The third argument should be of type (char **). The location pointed
-**   to is populated with a pointer to a nul-terminated string containing
-**   the string representation of a Tcl data-structure. The returned 
-**   string should be eventually freed by the caller using lsm_free().
-**
-**   The Tcl structure returned is a list containing one element for each
-**   free block in the database. The element itself consists of two 
-**   integers - the block number and the id of the snapshot that freed it.
-**
-** LSM_INFO_CHECKPOINT_SIZE:
-**   The third argument should be of type (int *). The location pointed to
-**   by this argument is populated with the number of KB written to the
-**   database file since the most recent checkpoint.
-**
-** LSM_INFO_TREE_SIZE:
-**   If this value is passed as the second argument to an lsm_info() call, it
-**   should be followed by two arguments of type (int *) (for a total of four
-**   arguments).
-**
-**   At any time, there are either one or two tree structures held in shared
-**   memory that new database clients will access (there may also be additional
-**   tree structures being used by older clients - this API does not provide
-**   information on them). One tree structure - the current tree - is used to
-**   accumulate new data written to the database. The other tree structure -
-**   the old tree - is a read-only tree holding older data and may be flushed 
-**   to disk at any time.
-** 
-**   Assuming no error occurs, the location pointed to by the first of the two
-**   (int *) arguments is set to the size of the old in-memory tree in KB.
-**   The second is set to the size of the current, or live in-memory tree.
-**
-** LSM_INFO_COMPRESSION_ID:
-**   This value should be followed by a single argument of type 
-**   (unsigned int *). If successful, the location pointed to is populated 
-**   with the database compression id before returning.

-**
-** A checkpoint represents the database layout at a single point in time.

-#include "lsmInt.h"
-
-/*
-** CHECKPOINT BLOB FORMAT:
-**
-** A checkpoint blob is a series of unsigned 32-bit integers stored in
-** big-endian byte order. As follows:
-**
-**   Checkpoint header (see the CKPT_HDR_XXX #defines):
-**
-**     1. The checkpoint id MSW.
-**     2. The checkpoint id LSW.
-**     3. The number of integer values in the entire checkpoint, including 
-**        the two checksum values.
-**     4. The compression scheme id.
-**     5. The total number of blocks in the database.
-**     6. The block size.
-**     7. The number of levels.
-**     8. The nominal database page size.
-**     9. The number of pages (in total) written to the database file.
-**
-**   Log pointer:
-**
-**     1. The log offset MSW.
-**     2. The log offset LSW.
-**     3. Log checksum 0.
-**     4. Log checksum 1.
-**
-**     Note that the "log offset" is not the literal byte offset. Instead,
-**     it is the byte offset multiplied by 2, with least significant bit
-**     toggled each time the log pointer value is changed. This is to make
-**     sure that this field changes each time the log pointer is updated,
-**     even if the log file itself is disabled. See lsmTreeMakeOld().
-**
-**     See ckptExportLog() and ckptImportLog().
-**
-**   Append points:
-**
-**     8 integers (4 * 64-bit page numbers). See ckptExportAppendlist().
-**
-**   For each level in the database, a level record. Formatted as follows:
-**
-**     0. Age of the level (least significant 16-bits). And flags mask (most
-**        significant 16-bits).
-**     1. The number of right-hand segments (nRight, possibly 0),
-**     2. Segment record for left-hand segment (8 integers defined below),
-**     3. Segment record for each right-hand segment (8 integers defined below),
-**     4. If nRight>0, The number of segments involved in the merge
-**     5. if nRight>0, Current nSkip value (see Merge structure defn.),
-**     6. For each segment in the merge:
-**        5a. Page number of next cell to read during merge (this field
-**            is 64-bits - 2 integers)
-**        5b. Cell number of next cell to read during merge
-**     7. Page containing current split-key (64-bits - 2 integers).
-**     8. Cell within page containing current split-key.
-**     9. Current pointer value (64-bits - 2 integers).
-**
-**   The block redirect array:
-**
-**     1. Number of redirections (maximum LSM_MAX_BLOCK_REDIRECTS).
-**     2. For each redirection:
-**        a. "from" block number
-**        b. "to" block number
-**
-**   The in-memory freelist entries. Each entry is either an insert or a
-**   delete. The in-memory freelist is to the free-block-list as the
-**   in-memory tree is to the users database content.
-**
-**     1. Number of free-list entries stored in checkpoint header.
-**     2. Number of free blocks (in total).
-**     3. Total number of blocks freed during database lifetime.
-**     4. For each entry:
-**        2a. Block number of free block.
-**        2b. A 64-bit integer (MSW followed by LSW). -1 for a delete entry,
-**            or the associated checkpoint id for an insert.
-**
-**   The checksum:
-**
-**     1. Checksum value 1.
-**     2. Checksum value 2.
-**
-** In the above, a segment record consists of the following four 64-bit 
-** fields (converted to 2 * u32 by storing the MSW followed by LSW):
-**
-**     1. First page of array,
-**     2. Last page of array,
-**     3. Root page of array (or 0),
-**     4. Size of array in pages.
-*/
-
-/*
-** LARGE NUMBERS OF LEVEL RECORDS:
-**
-** A limit on the number of rhs segments that may be present in the database
-** file. Defining this limit ensures that all level records fit within
-** the 4096 byte limit for checkpoint blobs.
-**
-** The number of right-hand-side segments in a database is counted as 
-** follows:
-**
-**   * For each level in the database not undergoing a merge, add 1.
-**
-**   * For each level in the database that is undergoing a merge, add 
-**     the number of segments on the rhs of the level.
-**
-** A level record not undergoing a merge is 10 integers. A level record 
-** with nRhs rhs segments and (nRhs+1) input segments (i.e. including the 
-** separators from the next level) is (11*nRhs+20) integers. The maximum
-** per right-hand-side level is therefore 21 integers. So the maximum
-** size of all level records in a checkpoint is 21*40=820 integers.
-**
-** TODO: Before pointer values were changed from 32 to 64 bits, the above
-** used to come to 420 bytes - leaving significant space for a free-list
-** prefix. No more. To fix this, reduce the size of the level records in
-** a db snapshot, and improve management of the free-list tail in 
-** lsm_sorted.c. 
-*/
-#define LSM_MAX_RHS_SEGMENTS 40
-
-/*
-** LARGE NUMBERS OF FREELIST ENTRIES:
-**
-** There is also a limit (LSM_MAX_FREELIST_ENTRIES - defined in lsmInt.h)
-** on the number of free-list entries stored in a checkpoint. Since each 
-** free-list entry consists of 3 integers, the maximum free-list size is 
-** 3*100=300 integers. Combined with the limit on rhs segments defined
-** above, this ensures that a checkpoint always fits within a 4096 byte
-** meta page.
-**
-** If the database contains more than 100 free blocks, the "overflow" flag
-** in the checkpoint header is set and the remainder are stored in the
-** system FREELIST entry in the LSM (along with user data). The value
-** accompanying the FREELIST key in the LSM is, like a checkpoint, an array
-** of 32-bit big-endian integers. As follows:
-**
-**     For each entry:
-**       a. Block number of free block.
-**       b. MSW of associated checkpoint id.
-**       c. LSW of associated checkpoint id.
-**
-** The number of entries is not required - it is implied by the size of the
-** value blob containing the integer array.
-**
-** Note that the limit defined by LSM_MAX_FREELIST_ENTRIES is a hard limit.
-** The actual value used may be configured using LSM_CONFIG_MAX_FREELIST.

-*************************************************************************
-** 
-** NORMAL DATABASE FILE FORMAT
-**
-** The following database file format concepts are used by the code in
-** this file to read and write the database file.
-**
-** Pages:
-**
-**   A database file is divided into pages. The first 8KB of the file consists
-**   of two 4KB meta-pages. The meta-page size is not configurable. The 
-**   remainder of the file is made up of database pages. The default database
-**   page size is 4KB. Database pages are aligned to page-size boundaries,
-**   so if the database page size is larger than 8KB there is a gap between
-**   the end of the meta pages and the start of the database pages.
-**
-**   Database pages are numbered based on their position in the file. Page N
-**   begins at byte offset ((N-1)*pgsz). This means that page 1 does not 
-**   exist - since it would always overlap with the meta pages. If the 
-**   page-size is (say) 512 bytes, then the first usable page in the database
-**   is page 33.
-**
-**   It is assumed that the first two meta pages and the data that follows
-**   them are located on different disk sectors. So that if a power failure 
-**   while writing to a meta page there is no risk of damage to the other
-**   meta page or any other part of the database file. TODO: This may need
-**   to be revisited.
-**
-** Blocks:
-**
-**   The database file is also divided into blocks. The default block size is
-**   1MB. When writing to the database file, an attempt is made to write data
-**   in contiguous block-sized chunks.
-**
-**   The first and last page on each block are special in that they are 4 
-**   bytes smaller than all other pages. This is because the last four bytes 
-**   of space on the first and last pages of each block are reserved for
-**   pointers to other blocks (i.e. a 32-bit block number).
-**
-** Runs:
-**
-**   A run is a sequence of pages that the upper layer uses to store a 
-**   sorted array of database keys (and accompanying data - values, FC 
-**   pointers and so on). Given a page within a run, it is possible to
-**   navigate to the next page in the run as follows:
-**
-**     a) if the current page is not the last in a block, the next page 
-**        in the run is located immediately after the current page, OR
-**
-**     b) if the current page is the last page in a block, the next page 
-**        in the run is the first page on the block identified by the
-**        block pointer stored in the last 4 bytes of the current block.
-**
-**   It is possible to navigate to the previous page in a similar fashion,
-**   using the block pointer embedded in the last 4 bytes of the first page
-**   of each block as required.
-**
-**   The upper layer is responsible for identifying by page number the 
-**   first and last page of any run that it needs to navigate - there are
-**   no "end-of-run" markers stored or identified by this layer. This is
-**   necessary as clients reading different database snapshots may access 
-**   different subsets of a run.
-**
-** THE LOG FILE 
-**
-** This file opens and closes the log file. But it does not contain any
-** logic related to the log file format. Instead, it exports the following
-** functions that are used by the code in lsm_log.c to read and write the
-** log file:
-**
-**     lsmFsOpenLog
-**     lsmFsWriteLog
-**     lsmFsSyncLog
-**     lsmFsReadLog
-**     lsmFsTruncateLog
-**     lsmFsCloseAndDeleteLog
-**
-** COMPRESSED DATABASE FILE FORMAT
-**
-** The compressed database file format is very similar to the normal format.
-** The file still begins with two 4KB meta-pages (which are never compressed).
-** It is still divided into blocks.
-**
-** The first and last four bytes of each block are reserved for 32-bit 
-** pointer values. Similar to the way four bytes are carved from the end of 
-** the first and last page of each block in uncompressed databases. From
-** the point of view of the upper layer, all pages are the same size - this
-** is different from the uncompressed format where the first and last pages
-** on each block are 4 bytes smaller than the others.
-**
-** Pages are stored in variable length compressed form, as follows:
-**
-**     * 3-byte size field containing the size of the compressed page image
-**       in bytes. The most significant bit of each byte of the size field
-**       is always set. The remaining 7 bits are used to store a 21-bit
-**       integer value (in big-endian order - the first byte in the field
-**       contains the most significant 7 bits). Since the maximum allowed 
-**       size of a compressed page image is (2^17 - 1) bytes, there are
-**       actually 4 unused bits in the size field.
-**
-**       In other words, if the size of the compressed page image is nSz,
-**       the header can be serialized as follows:
-**
-**         u8 aHdr[3]
-**         aHdr[0] = 0x80 | (u8)(nSz >> 14);
-**         aHdr[1] = 0x80 | (u8)(nSz >>  7);
-**         aHdr[2] = 0x80 | (u8)(nSz >>  0);
-**
-**     * Compressed page image.
-**
-**     * A second copy of the 3-byte record header.
-**
-** A page number is a byte offset into the database file. So the smallest
-** possible page number is 8192 (immediately after the two meta-pages).
-** The first and root page of a segment are identified by a page number
-** corresponding to the byte offset of the first byte in the corresponding
-** page record. The last page of a segment is identified by the byte offset
-** of the last byte in its record.
-**
-** Unlike uncompressed pages, compressed page records may span blocks.
-**
-** Sometimes, in order to avoid touching sectors that contain synced data
-** when writing, it is necessary to insert unused space between compressed
-** page records. This can be done as follows:
-**
-**     * For less than 6 bytes of empty space, the first and last byte
-**       of the free space contain the total number of free bytes. For
-**       example:
-**
-**         Block of 4 free bytes: 0x04 0x?? 0x?? 0x04
-**         Block of 2 free bytes: 0x02 0x02
-**         A single free byte:    0x01
-**
-**     * For 6 or more bytes of empty space, a record similar to a 
-**       compressed page record is added to the segment. A padding record
-**       is distinguished from a compressed page record by the most 
-**       significant bit of the second byte of the size field, which is
-**       cleared instead of set.

-/*
-** File-system object. Each database connection allocates a single instance
-** of the following structure. It is used for all access to the database and
-** log files.
-**
-** The database file may be accessed via two methods - using mmap() or using
-** read() and write() calls. In the general case both methods are used - a
-** prefix of the file is mapped into memory and the remainder accessed using
-** read() and write(). This is helpful when accessing very large files (or
-** files that may grow very large during the lifetime of a database
-** connection) on systems with 32-bit address spaces. However, it also requires
-** that this object manage two distinct types of Page objects simultaneously -
-** those that carry pointers to the mapped file and those that carry arrays
-** populated by read() calls.
-**
-** pFree:
-**   The head of a singly-linked list that containing currently unused Page 
-**   structures suitable for use as mmap-page handles. Connected by the
-**   Page.pFreeNext pointers.
-**
-** pMapped:
-**   The head of a singly-linked list that contains all pages that currently
-**   carry pointers to the mapped region. This is used if the region is
-**   every remapped - the pointers carried by existing pages can be adjusted
-**   to account for the remapping. Connected by the Page.pMappedNext pointers.
-**
-** pWaiting:
-**   When the upper layer wishes to append a new b-tree page to a segment,
-**   it allocates a Page object that carries a malloc'd block of memory -
-**   regardless of the mmap-related configuration. The page is not assigned
-**   a page number at first. When the upper layer has finished constructing
-**   the page contents, it calls lsmFsPagePersist() to assign a page number
-**   to it. At this point it is likely that N pages have been written to the
-**   segment, the (N+1)th page is still outstanding and the b-tree page is
-**   assigned page number (N+2). To avoid writing page (N+2) before page 
-**   (N+1), the recently completed b-tree page is held in the singly linked
-**   list headed by pWaiting until page (N+1) has been written. 
-**
-**   Function lsmFsFlushWaiting() is responsible for eventually writing 
-**   waiting pages to disk.
-**
-** apHash/nHash:
-**   Hash table used to store all Page objects that carry malloc'd arrays,
-**   except those b-tree pages that have not yet been assigned page numbers.
-**   Once they have been assigned page numbers - they are added to this
-**   hash table.
-**
-**   Hash table overflow chains are connected using the Page.pHashNext
-**   pointers.
-**
-** pLruFirst, pLruLast:
-**   The first and last entries in a doubly-linked list of pages. This
-**   list contains all pages with malloc'd data that are present in the
-**   hash table and have a ref-count of zero.

-*************************************************************************
-**
-** This file contains the implementation of LSM database logging. Logging
-** has one purpose in LSM - to make transactions durable.
-**
-** When data is written to an LSM database, it is initially stored in an
-** in-memory tree structure. Since this structure is in volatile memory,
-** if a power failure or application crash occurs it may be lost. To
-** prevent loss of data in this case, each time a record is written to the
-** in-memory tree an equivalent record is appended to the log on disk.
-** If a power failure or application crash does occur, data can be recovered
-** by reading the log.
-**
-** A log file consists of the following types of records representing data
-** written into the database:
-**
-**   LOG_WRITE:  A key-value pair written to the database.
-**   LOG_DELETE: A delete key issued to the database.
-**   LOG_COMMIT: A transaction commit.
-**
-** And the following types of records for ancillary purposes..
-**
-**   LOG_EOF:    A record indicating the end of a log file.
-**   LOG_PAD1:   A single byte padding record.
-**   LOG_PAD2:   An N byte padding record (N>1).
-**   LOG_JUMP:   A pointer to another offset within the log file.
-**
-** Each transaction written to the log contains one or more LOG_WRITE and/or
-** LOG_DELETE records, followed by a LOG_COMMIT record. The LOG_COMMIT record
-** contains an 8-byte checksum based on all previous data written to the
-** log file.
-**
-** LOG CHECKSUMS & RECOVERY
-**
-**   Checksums are found in two types of log records: LOG_COMMIT and
-**   LOG_CKSUM records. In order to recover content from a log, a client
-**   reads each record from the start of the log, calculating a checksum as
-**   it does. Each time a LOG_COMMIT or LOG_CKSUM is encountered, the 
-**   recovery process verifies that the checksum stored in the log 
-**   matches the calculated checksum. If it does not, the recovery process
-**   can stop reading the log.
-**
-**   If a recovery process reads records (other than COMMIT or CKSUM) 
-**   consisting of at least LSM_CKSUM_MAXDATA bytes, then the next record in
-**   the log must be either a LOG_CKSUM or LOG_COMMIT record. If it is
-**   not, the recovery process also stops reading the log.
-**
-**   To recover the log file, it must be read twice. The first time to 
-**   determine the location of the last valid commit record. And the second
-**   time to load data into the in-memory tree.
-**
-**   Todo: Surely there is a better way...
-**
-** LOG WRAPPING
-**
-**   If the log file were never deleted or wrapped, it would be possible to
-**   read it from start to end each time is required recovery (i.e each time
-**   the number of database clients changes from 0 to 1). Effectively reading
-**   the entire history of the database each time. This would quickly become 
-**   inefficient. Additionally, since the log file would grow without bound,
-**   it wastes storage space.
-**
-**   Instead, part of each checkpoint written into the database file contains 
-**   a log offset (and other information required to read the log starting at
-**   at this offset) at which to begin recovery. Offset $O.
-**
-**   Once a checkpoint has been written and synced into the database file, it
-**   is guaranteed that no recovery process will need to read any data before
-**   offset $O of the log file. It is therefore safe to begin overwriting
-**   any data that occurs before offset $O.
-**
-**   This implementation separates the log into three regions mapped into
-**   the log file - regions 0, 1 and 2. During recovery, regions are read
-**   in ascending order (i.e. 0, then 1, then 2). Each region is zero or
-**   more bytes in size.
-**
-**     |---1---|..|--0--|.|--2--|....
-**
-**   New records are always appended to the end of region 2.
-**
-**   Initially (when it is empty), all three regions are zero bytes in size.
-**   Each of them are located at the beginning of the file. As records are
-**   added to the log, region 2 grows, so that the log consists of a zero
-**   byte region 1, followed by a zero byte region 0, followed by an N byte
-**   region 2. After one or more checkpoints have been written to disk, 
-**   the start point of region 2 is moved to $O. For example:
-**
-**     A) ||.........|--2--|....
-**   
-**   (both regions 0 and 1 are 0 bytes in size at offset 0).
-**
-**   Eventually, the log wraps around to write new records into the start.
-**   At this point, region 2 is renamed to region 0. Region 0 is renamed
-**   to region 2. After appending a few records to the new region 2, the
-**   log file looks like this:
-**
-**     B) ||--2--|...|--0--|....
-**
-**   (region 1 is still 0 bytes in size, located at offset 0).
-**
-**   Any checkpoints made at this point may reduce the size of region 0.
-**   However, if they do not, and region 2 expands so that it is about to
-**   overwrite the start of region 0, then region 2 is renamed to region 1,
-**   and a new region 2 created at the end of the file following the existing
-**   region 0.
-**
-**     C) |---1---|..|--0--|.|-2-|
-**
-**   In this state records are appended to region 2 until checkpoints have
-**   contracted regions 0 AND 1 UNTil they are both zero bytes in size. They 
-**   are then shifted to the start of the log file, leaving the system in 
-**   the equivalent of state A above.
-**
-**   Alternatively, state B may transition directly to state A if the size
-**   of region 0 is reduced to zero bytes before region 2 threatens to 
-**   encroach upon it.
-**
-** LOG_PAD1 & LOG_PAD2 RECORDS
-**
-**   PAD1 and PAD2 records may appear in a log file at any point. They allow
-**   a process writing the log file align the beginning of transactions with 
-**   the beginning of disk sectors, which increases robustness.
-**
-** RECORD FORMATS:
-**
-**   LOG_EOF:    * A single 0x00 byte.
-**
-**   LOG_PAD1:   * A single 0x01 byte.
-**
-**   LOG_PAD2:   * A single 0x02 byte, followed by
-**               * The number of unused bytes (N) as a varint,
-**               * An N byte block of unused space.
-**
-**   LOG_COMMIT: * A single 0x03 byte.
-**               * An 8-byte checksum.
-**
-**   LOG_JUMP:   * A single 0x04 byte.
-**               * Absolute file offset to jump to, encoded as a varint.
-**
-**   LOG_WRITE:  * A single 0x06 or 0x07 byte, 
-**               * The number of bytes in the key, encoded as a varint, 
-**               * The number of bytes in the value, encoded as a varint, 
-**               * If the first byte was 0x07, an 8 byte checksum.
-**               * The key data,
-**               * The value data.
-**
-**   LOG_DELETE: * A single 0x08 or 0x09 byte, 
-**               * The number of bytes in the key, encoded as a varint, 
-**               * If the first byte was 0x09, an 8 byte checksum.
-**               * The key data.
-**
-**   Varints are as described in lsm_varint.c (SQLite 4 format).
-**
-** CHECKSUMS:
-**
-**   The checksum is calculated using two 32-bit unsigned integers, s0 and
-**   s1. The initial value for both is 42. It is updated each time a record
-**   is written into the log file by treating the encoded (binary) record as 
-**   an array of 32-bit little-endian integers. Then, if x[] is the integer
-**   array, updating the checksum accumulators as follows:
-**
-**     for i from 0 to n-1 step 2:
-**       s0 += x[i] + s1;
-**       s1 += x[i+1] + s0;
-**     endfor
-**
-**   If the record is not an even multiple of 8-bytes in size it is padded
-**   with zeroes to make it so before the checksum is updated.
-**
-**   The checksum stored in a COMMIT, WRITE or DELETE is based on all bytes
-**   up to the start of the 8-byte checksum itself, including the COMMIT,
-**   WRITE or DELETE fields that appear before the checksum in the record.

-*************************************************************************
-**
-** PAGE FORMAT:
-**
-**   The maximum page size is 65536 bytes.
-**
-**   Since all records are equal to or larger than 2 bytes in size, and 
-**   some space within the page is consumed by the page footer, there must
-**   be less than 2^15 records on each page.
-**
-**   Each page ends with a footer that describes the pages contents. This
-**   footer serves as similar purpose to the page header in an SQLite database.
-**   A footer is used instead of a header because it makes it easier to
-**   populate a new page based on a sorted list of key/value pairs.
-**
-**   The footer consists of the following values (starting at the end of
-**   the page and continuing backwards towards the start). All values are
-**   stored as unsigned big-endian integers.
-**
-**     * Number of records on page (2 bytes).
-**     * Flags field (2 bytes).
-**     * Left-hand pointer value (8 bytes).
-**     * The starting offset of each record (2 bytes per record).
-**
-**   Records may span pages. Unless it happens to be an exact fit, the part
-**   of the final record that starts on page X that does not fit on page X
-**   is stored at the start of page (X+1). This means there may be pages where
-**   (N==0). And on most pages the first record that starts on the page will
-**   not start at byte offset 0. For example:
-**
-**      aaaaa bbbbb ccc <footer>    cc eeeee fffff g <footer>    gggg....
-**
-** RECORD FORMAT:
-** 
-**   The first byte of the record is a flags byte. It is a combination
-**   of the following flags (defined in lsmInt.h):
-**
-**       LSM_START_DELETE
-**       LSM_END_DELETE 
-**       LSM_POINT_DELETE
-**       LSM_INSERT    
-**       LSM_SEPARATOR
-**       LSM_SYSTEMKEY
-**
-**   Immediately following the type byte is a pointer to the smallest key 
-**   in the next file that is larger than the key in the current record. The 
-**   pointer is encoded as a varint. When added to the 32-bit page number 
-**   stored in the footer, it is the page number of the page that contains the
-**   smallest key in the next sorted file that is larger than this key. 
-**
-**   Next is the number of bytes in the key, encoded as a varint.
-**
-**   If the LSM_INSERT flag is set, the number of bytes in the value, as
-**   a varint, is next.
-**
-**   Finally, the blob of data containing the key, and for LSM_INSERT
-**   records, the value as well.

-**
-** TODO: This is a stop-gap solution:

-**   At the moment, this function is called from within segmentPtrSeek(), 
-**   as part of the initial lsmMCursorSeek() call. However, consider a 
-**   database where the following has occurred:
-**
-**      1. A range delete removes keys 1..9999 using a range delete.
-**      2. Keys 1 through 9999 are reinserted.
-**      3. The levels containing the ops in 1. and 2. above are merged. Call
-**         this level N. Level N contains FC pointers to level N+1.
-**
-**   Then, if the user attempts to query for (key>=2 LIMIT 10), the

-** B-tree pages use almost the same format as regular pages. The

-**
-**   1. The record format is (usually, see below) as follows:
-**
-**         + Type byte (always SORTED_SEPARATOR or SORTED_SYSTEM_SEPARATOR),
-**         + Absolute pointer value (varint),
-**         + Number of bytes in key (varint),
-**         + LsmBlob containing key data.
-**
-**   2. All pointer values are stored as absolute values (not offsets 
-**      relative to the footer pointer value).
-**
-**   3. Each pointer that is part of a record points to a page that 
-**      contains keys smaller than the records key (note: not "equal to or
-**      smaller than - smaller than").
-**
-**   4. The pointer in the page footer of a b-tree page points to a page
-**      that contains keys equal to or larger than the largest key on the
-**      b-tree page.
-**
-** The reason for having the page footer pointer point to the right-child
-** (instead of the left) is that doing things this way makes the 
-** mergeWorkerMoveHierarchy() operation less complicated (since the pointers 
-** that need to be updated are all stored as fixed-size integers within the 
-** page footer, not varints in page records).
-**
-** Records may not span b-tree pages. If this function is called to add a
-** record larger than (page-size / 4) bytes, then a pointer to the indexed
-** array page that contains the main record is added to the b-tree instead.
-** In this case the record format is:
-**
-**         + 0x00 byte (1 byte) 
-**         + Absolute pointer value (varint),
-**         + Absolute page number of page containing key (varint).

-*************************************************************************
-**
-** This file contains the implementation of an in-memory tree structure.
-**
-** Technically the tree is a B-tree of order 4 (in the Knuth sense - each 
-** node may have up to 4 children). Keys are stored within B-tree nodes by
-** reference. This may be slightly slower than a conventional red-black
-** tree, but it is simpler. It is also an easier structure to modify to 
-** create a version that supports nested transaction rollback.
-**
-** This tree does not currently support a delete operation. One is not 
-** required. When LSM deletes a key from a database, it inserts a DELETE
-** marker into the data structure. As a result, although the value associated
-** with a key stored in the in-memory tree structure may be modified, no
-** keys are ever removed. 
-*/
-
-/*
-** MVCC NOTES
-**
-**   The in-memory tree structure supports SQLite-style MVCC. This means
-**   that while one client is writing to the tree structure, other clients
-**   may still be querying an older snapshot of the tree.
-**
-**   One way to implement this is to use an append-only b-tree. In this 
-**   case instead of modifying nodes in-place, a copy of the node is made
-**   and the required modifications made to the copy. The parent of the
-**   node is then modified (to update the pointer so that it points to
-**   the new copy), which causes a copy of the parent to be made, and so on.
-**   This means that each time the tree is written to a new root node is
-**   created. A snapshot is identified by the root node that it uses.
-**
-**   The problem with the above is that each time the tree is written to,
-**   a copy of the node structure modified and all of its ancestor nodes
-**   is made. This may prove excessive with large tree structures.
-**
-**   To reduce this overhead, the data structure used for a tree node is
-**   designed so that it may be edited in place exactly once without 
-**   affecting existing users. In other words, the node structure is capable
-**   of storing two separate versions of the node at the same time.
-**   When a node is to be edited, if the node structure already contains 
-**   two versions, a copy is made as in the append-only approach. Or, if
-**   it only contains a single version, it is edited in place.
-**
-**   This reduces the overhead so that, roughly, one new node structure
-**   must be allocated for each write (on top of those allocations that 
-**   would have been required by a non-MVCC tree). Logic: Assume that at 
-**   any time, 50% of nodes in the tree already contain 2 versions. When
-**   a new entry is written to a node, there is a 50% chance that a copy
-**   of the node will be required. And a 25% chance that a copy of its 
-**   parent is required. And so on.
-**
-** ROLLBACK
-**
-**   The in-memory tree also supports transaction and sub-transaction 
-**   rollback. In order to rollback to point in time X, the following is
-**   necessary:
-**
-**     1. All memory allocated since X must be freed, and 
-**     2. All "v2" data adding to nodes that existed at X should be zeroed.
-**     3. The root node must be restored to its X value.
-**
-**   The Mempool object used to allocate memory for the tree supports 
-**   operation (1) - see the lsmPoolMark() and lsmPoolRevert() functions.
-**
-**   To support (2), all nodes that have v2 data are part of a singly linked 
-**   list, sorted by the age of the v2 data (nodes that have had data added 
-**   most recently are at the end of the list). So to zero all v2 data added
-**   since X, the linked list is traversed from the first node added following
-**   X onwards.

-*************************************************************************
-**
-** This file implements a virtual table for SQLite3 around the LSM
-** storage engine from SQLite4.
-**
-** USAGE
-**
-**   CREATE VIRTUAL TABLE demo USING lsm1(filename,key,keytype,value1,...);
-**
-** The filename parameter is the name of the LSM database file, which is
-** separate and distinct from the SQLite3 database file.
-**
-** The keytype must be one of: UINT, TEXT, BLOB.  All keys must be of that
-** one type.  "UINT" means unsigned integer.  The values may be of any
-** SQLite datatype: BLOB, TEXT, INTEGER, FLOAT, or NULL.
-**
-** The virtual table contains read-only hidden columns:
-**
-**     lsm1_key	      A BLOB which is the raw LSM key.  If the "keytype"
-**                    is BLOB or TEXT then this column is exactly the
-**                    same as the key.  For the UINT keytype, this column
-**                    will be a variable-length integer encoding of the key.
-**
-**     lsm1_value     A BLOB which is the raw LSM value.  All of the value
-**                    columns are packed into this BLOB using the encoding
-**                    described below.
-**
-** Attempts to write values into the lsm1_key and lsm1_value columns are
-** silently ignored.
-**
-** EXAMPLE
-**
-** The virtual table declared this way:
-**
-**    CREATE VIRTUAL TABLE demo2 USING lsm1('x.lsm',id,UINT,a,b,c,d);
-**
-** Results in a new virtual table named "demo2" that acts as if it has
-** the following schema:
-**
-**    CREATE TABLE demo2(
-**      id UINT PRIMARY KEY ON CONFLICT REPLACE,
-**      a ANY,
-**      b ANY,
-**      c ANY,
-**      d ANY,
-**      lsm1_key BLOB HIDDEN,
-**      lsm1_value BLOB HIDDEN
-**    ) WITHOUT ROWID;
-**
-** 
-**
-** INTERNALS
-**
-** The key encoding for BLOB and TEXT is just a copy of the blob or text.
-** UTF-8 is used for text.  The key encoding for UINT is the variable-length
-** integer format at https://sqlite.org/src4/doc/trunk/www/varint.wiki.
-**
-** The values are encoded as a single blob (since that is what lsm stores as
-** its content).  There is a "type integer" followed by "content" for each
-** value, alternating back and forth.  The content might be empty.
-**
-**    TYPE1  CONTENT1  TYPE2  CONTENT2  TYPE3  CONTENT3 ....
-**
-** Each "type integer" is encoded as a variable-length integer in the
-** format of the link above.  Let the type integer be T.  The actual
-** datatype is an integer 0-5 equal to T%6.  Values 1 through 5 correspond
-** to SQLITE_INTEGER through SQLITE_NULL.  The size of the content in bytes
-** is T/6.  Type value 0 means that the value is an integer whose actual
-** values is T/6 and there is no content.  The type-value-0 integer format
-** only works for integers in the range of 0 through 40.
-**
-** There is no content for NULL or type-0 integers.  For BLOB and TEXT
-** values, the content is the blob data or the UTF-8 text data.  For
-** non-negative integers X, the content is a variable-length integer X*2.
-** For negative integers Y, the content is varaible-length integer (1-Y)*2+1.
-** For FLOAT values, the content is the IEEE754 floating point value in
-** native byte-order.  This means that FLOAT values will be corrupted when
-** database file is moved between big-endian and little-endian machines.

-## Miscellaneous Extensions
-
-This folder contains a collection of smaller loadable extensions.
-See <https://www.sqlite.org/loadext.html> for instructions on how
-to compile and use loadable extensions.
-Each extension in this folder is implemented in a single file of C code.
-
-Each source file contains a description in its header comment.  See the
-header comments for details about each extension.  Additional notes are
-as follows:
-
-  *  **carray.c** &mdash;  This module implements the
-     [carray](https://www.sqlite.org/carray.html) table-valued function.
-     It is a good example of how to go about implementing a custom
-     [table-valued function](https://www.sqlite.org/vtab.html#tabfunc2).
-
-  *  **csv.c** &mdash;  A [virtual table](https://sqlite.org/vtab.html)
-     for reading 
-     [Comma-Separated-Value (CSV) files](https://en.wikipedia.org/wiki/Comma-separated_values).
-
-  *  **dbdump.c** &mdash;  This is not actually a loadable extension, but
-     rather a library that implements an approximate equivalent to the
-     ".dump" command of the
-     [command-line shell](https://www.sqlite.org/cli.html).
-
-  *  **json1.c** &mdash;  Various SQL functions and table-valued functions
-     for processing JSON.  This extension is already built into the
-     [SQLite amalgamation](https://sqlite.org/amalgamation.html).  See
-     <https://sqlite.org/json1.html> for additional information.
-
-  *  **memvfs.c** &mdash;  This file implements a custom
-     [VFS](https://www.sqlite.org/vfs.html) that stores an entire database
-     file in a single block of RAM.  It serves as a good example of how
-     to implement a simple custom VFS.
-
-  *  **rot13.c** &mdash;  This file implements the very simple rot13()
-     substitution function.  This file makes a good template for implementing
-     new custom SQL functions for SQLite.
-
-  *  **series.c** &mdash;  This is an implementation of the
-     "generate_series" [virtual table](https://www.sqlite.org/vtab.html).
-     It can make a good template for new custom virtual table implementations.
-
-  *  **shathree.c** &mdash;  An implementation of the sha3() and
-     sha3_query() SQL functions.  The file is named "shathree.c" instead
-     of "sha3.c" because the default entry point names in SQLite are based
-     on the source filename with digits removed, so if we used the name
-     "sha3.c" then the entry point would conflict with the prior "sha1.c"
-     extension.
-
-  *  **unionvtab.c** &mdash; Implementation of the unionvtab and
-     [swarmvtab](https://sqlite.org/swarmvtab.html) virtual tables.
-     These virtual tables allow a single
-     large table to be spread out across multiple database files.  In the
-     case of swarmvtab, the individual database files can be attached on
-     demand.
-
-  *  **zipfile.c** &mdash;  A [virtual table](https://sqlite.org/vtab.html)
-     that can read and write a 
-     [ZIP archive](https://en.wikipedia.org/wiki/Zip_%28file_format%29).

-*************************************************************************
-**
-** This file contains code for a demonstration virtual table that finds
-** "approximate matches" - strings from a finite set that are nearly the
-** same as a single input string.  The virtual table is called "amatch".
-**
-** A amatch virtual table is created like this:
-**
-**     CREATE VIRTUAL TABLE f USING approximate_match(
-**        vocabulary_table=<tablename>,      -- V
-**        vocabulary_word=<columnname>,      -- W
-**        vocabulary_language=<columnname>,  -- L
-**        edit_distances=<edit-cost-table>
-**     );
-**
-** When it is created, the new amatch table must be supplied with the
-** the name of a table V and columns V.W and V.L such that 
-**
-**     SELECT W FROM V WHERE L=$language
-**
-** returns the allowed vocabulary for the match.  If the "vocabulary_language"
-** or L columnname is left unspecified or is an empty string, then no
-** filtering of the vocabulary by language is performed. 
-**
-** For efficiency, it is essential that the vocabulary table be indexed:
-**
-**     CREATE vocab_index ON V(W)
-**
-** A separate edit-cost-table provides scoring information that defines 
-** what it means for one string to be "close" to another.
-**
-** The edit-cost-table must contain exactly four columns (more precisely,
-** the statement "SELECT * FROM <edit-cost-table>" must return records
-** that consist of four columns). It does not matter what the columns are
-** named. 
-**
-** Each row in the edit-cost-table represents a single character
-** transformation going from user input to the vocabulary. The leftmost 
-** column of the row (column 0) contains an integer identifier of the
-** language to which the transformation rule belongs (see "MULTIPLE LANGUAGES"
-** below). The second column of the row (column 1) contains the input
-** character or characters - the characters of user input. The third 
-** column contains characters as they appear in the vocabulary table.
-** And the fourth column contains the integer cost of making the
-** transformation. For example:
-**
-**    CREATE TABLE f_data(iLang, cFrom, cTo, Cost);
-**    INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '', 'a', 100);
-**    INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, 'b', '', 87);
-**    INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, 'o', 'oe', 38);
-**    INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, 'oe', 'o', 40);
-**
-** The first row inserted into the edit-cost-table by the SQL script
-** above indicates that the cost of having an extra 'a' in the vocabulary
-** table that is missing in the user input 100.  (All costs are integers.
-** Overall cost must not exceed 16777216.)  The second INSERT statement 
-** creates a rule saying that the cost of having a single letter 'b' in
-** user input which is missing in the vocabulary table is 87.  The third
-** INSERT statement mean that the cost of matching an 'o' in user input 
-** against an 'oe' in the vocabulary table is 38.  And so forth.
-**
-** The following rules are special:
-**
-**    INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '?', '', 97);
-**    INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '', '?', 98);
-**    INSERT INTO f_data(iLang, cFrom, cTo, Cost) VALUES(0, '?', '?', 99);
-**
-** The '?' to '' rule is the cost of having any single character in the input
-** that is not found in the vocabular.  The '' to '?' rule is the cost of
-** having a character in the vocabulary table that is missing from input.
-** And the '?' to '?' rule is the cost of doing an arbitrary character
-** substitution.  These three generic rules apply across all languages.
-** In other words, the iLang field is ignored for the generic substitution
-** rules.  If more than one cost is given for a generic substitution rule,
-** then the lowest cost is used.
-**
-** Once it has been created, the amatch virtual table can be queried
-** as follows:
-**
-**    SELECT word, distance FROM f
-**     WHERE word MATCH 'abcdefg'
-**       AND distance<200;
-**
-** This query outputs the strings contained in the T(F) field that
-** are close to "abcdefg" and in order of increasing distance.  No string
-** is output more than once.  If there are multiple ways to transform the
-** target string ("abcdefg") into a string in the vocabulary table then
-** the lowest cost transform is the one that is returned.  In this example,
-** the search is limited to strings with a total distance of less than 200.
-**
-** For efficiency, it is important to put tight bounds on the distance.
-** The time and memory space needed to perform this query is exponential
-** in the maximum distance.  A good rule of thumb is to limit the distance
-** to no more than 1.5 or 2 times the maximum cost of any rule in the
-** edit-cost-table.
-**
-** The amatch is a read-only table.  Any attempt to DELETE, INSERT, or
-** UPDATE on a amatch table will throw an error.
-**
-** It is important to put some kind of a limit on the amatch output.  This
-** can be either in the form of a LIMIT clause at the end of the query,
-** or better, a "distance<NNN" constraint where NNN is some number.  The
-** running time and memory requirement is exponential in the value of NNN 
-** so you want to make sure that NNN is not too big.  A value of NNN that
-** is about twice the average transformation cost seems to give good results.
-**
-** The amatch table can be useful for tasks such as spelling correction.
-** Suppose all allowed words are in table vocabulary(w).  Then one would create
-** an amatch virtual table like this:
-**
-**   CREATE VIRTUAL TABLE ex1 USING amatch(
-**       vocabtable=vocabulary,
-**       vocabcolumn=w,
-**       edit_distances=ec1
-**   );
-**
-** Then given an input word $word, look up close spellings this way:
-**
-**   SELECT word, distance FROM ex1
-**    WHERE word MATCH $word AND distance<200;
-**
-** MULTIPLE LANGUAGES
-**
-** Normally, the "iLang" value associated with all character transformations
-** in the edit-cost-table is zero. However, if required, the amatch 
-** virtual table allows multiple languages to be defined. Each query uses 
-** only a single iLang value.   This allows, for example, a single 
-** amatch table to support multiple languages.
-**
-** By default, only the rules with iLang=0 are used. To specify an 
-** alternative language, a "language = ?" expression must be added to the
-** WHERE clause of a SELECT, where ? is the integer identifier of the desired 
-** language. For example:
-**
-**   SELECT word, distance FROM ex1
-**    WHERE word MATCH $word
-**      AND distance<=200

-******************************************************************************

-** This file implements a VFS shim that allows an SQLite database to be
-** appended onto the end of some other file, such as an executable.
-**
-** A special record must appear at the end of the file that identifies the
-** file as an appended database and provides an offset to page 1.  For
-** best performance page 1 should be located at a disk page boundary, though
-** that is not required.
-**
-** When opening a database using this VFS, the connection might treat
-** the file as an ordinary SQLite database, or it might treat is as a
-** database appended onto some other file.  Here are the rules:
-**
-**  (1)  When opening a new empty file, that file is treated as an ordinary
-**       database.
-**
-**  (2)  When opening a file that begins with the standard SQLite prefix
-**       string "SQLite format 3", that file is treated as an ordinary
-**       database.
-**
-**  (3)  When opening a file that ends with the appendvfs trailer string
-**       "Start-Of-SQLite3-NNNNNNNN" that file is treated as an appended
-**       database.
-**
-**  (4)  If none of the above apply and the SQLITE_OPEN_CREATE flag is
-**       set, then a new database is appended to the already existing file.
-**
-**  (5)  Otherwise, SQLITE_CANTOPEN is returned.
-**
-** To avoid unnecessary complications with the PENDING_BYTE, the size of
-** the file containing the database is limited to 1GB.  This VFS will refuse
-** to read or write past the 1GB mark.  This restriction might be lifted in
-** future versions.  For now, if you need a large database, then keep the
-** database in a separate file.
-**
-** If the file being opened is not an appended database, then this shim is
-** a pass-through into the default underlying VFS.

-******************************************************************************
-**
-** This file contains an implementation of the "sqlite_btreeinfo" virtual table.
-**
-** The sqlite_btreeinfo virtual table is a read-only eponymous-only virtual
-** table that shows information about all btrees in an SQLite database file.
-** The schema is like this:
-**
-** CREATE TABLE sqlite_btreeinfo(
-**    type TEXT,                   -- "table" or "index"
-**    name TEXT,                   -- Name of table or index for this btree.
-**    tbl_name TEXT,               -- Associated table
-**    rootpage INT,                -- The root page of the btree
-**    sql TEXT,                    -- SQL for this btree - from sqlite_master
-**    hasRowid BOOLEAN,            -- True if the btree has a rowid
-**    nEntry INT,                  -- Estimated number of enteries
-**    nPage INT,                   -- Estimated number of pages
-**    depth INT,                   -- Depth of the btree
-**    szPage INT,                  -- Size of each page in bytes
-**    zSchema TEXT HIDDEN          -- The schema to which this btree belongs
-** );
-**
-** The first 5 fields are taken directly from the sqlite_master table.
-** Considering only the first 5 fields, the only difference between 
-** this virtual table and the sqlite_master table is that this virtual
-** table omits all entries that have a 0 or NULL rowid - in other words
-** it omits triggers and views.
-**
-** The value added by this table comes in the next 5 fields.
-**
-** Note that nEntry and nPage are *estimated*.  They are computed doing
-** a single search from the root to a leaf, counting the number of cells
-** at each level, and assuming that unvisited pages have a similar number
-** of cells.
-**
-** The sqlite_dbpage virtual table must be available for this virtual table
-** to operate.
-**
-** USAGE EXAMPLES:
-**
-** Show the table btrees in a schema order with the tables with the most
-** rows occuring first:
-**
-**      SELECT name, nEntry
-**        FROM sqlite_btreeinfo
-**       WHERE type='table'
-**       ORDER BY nEntry DESC, name;
-**
-** Show the names of all WITHOUT ROWID tables: 
-**
-**      SELECT name FROM sqlite_btreeinfo
-**       WHERE type='table' AND NOT hasRowid;

-*************************************************************************
-**
-** This file demonstrates how to create a table-valued-function that
-** returns the values in a C-language array.
-** Examples:
-**
-**      SELECT * FROM carray($ptr,5)
-**
-** The query above returns 5 integers contained in a C-language array
-** at the address $ptr.  $ptr is a pointer to the array of integers.
-** The pointer value must be assigned to $ptr using the
-** sqlite3_bind_pointer() interface with a pointer type of "carray".
-** For example:
-**
-**    static int aX[] = { 53, 9, 17, 2231, 4, 99 };
-**    int i = sqlite3_bind_parameter_index(pStmt, "$ptr");
-**    sqlite3_bind_value(pStmt, i, aX, "carray", 0);
-**
-** There is an optional third parameter to determine the datatype of
-** the C-language array.  Allowed values of the third parameter are
-** 'int32', 'int64', 'double', 'char*'.  Example:
-**
-**      SELECT * FROM carray($ptr,10,'char*');
-**
-** The default value of the third parameter is 'int32'.
-**
-** HOW IT WORKS
-**
-** The carray "function" is really a virtual table with the
-** following schema:
-**
-**     CREATE TABLE carray(
-**       value,
-**       pointer HIDDEN,
-**       count HIDDEN,
-**       ctype TEXT HIDDEN
-**     );
-**
-** If the hidden columns "pointer" and "count" are unconstrained, then 
-** the virtual table has no rows.  Otherwise, the virtual table interprets
-** the integer value of "pointer" as a pointer to the array and "count"
-** as the number of elements in the array.  The virtual table steps through
-** the array, element by element.

-*************************************************************************
-**
-** This file contains code for a virtual table that finds the transitive
-** closure of a parent/child relationship in a real table.  The virtual 
-** table is called "transitive_closure".
-**
-** A transitive_closure virtual table is created like this:
-**
-**     CREATE VIRTUAL TABLE x USING transitive_closure(
-**        tablename=<tablename>,      -- T
-**        idcolumn=<columnname>,      -- X
-**        parentcolumn=<columnname>   -- P
-**     );
-**
-** When it is created, the new transitive_closure table may be supplied 
-** with default values for the name of a table T and columns T.X and T.P.
-** The T.X and T.P columns must contain integers.  The ideal case is for 
-** T.X to be the INTEGER PRIMARY KEY.  The T.P column should reference
-** the T.X column. The row referenced by T.P is the parent of the current row.
-**
-** The tablename, idcolumn, and parentcolumn supplied by the CREATE VIRTUAL
-** TABLE statement may be overridden in individual queries by including
-** terms like tablename='newtable', idcolumn='id2', or 
-** parentcolumn='parent3' in the WHERE clause of the query.
-**
-** For efficiency, it is essential that there be an index on the P column:
-**
-**    CREATE Tidx1 ON T(P)
-**
-** Suppose a specific instance of the closure table is as follows:
-**
-**    CREATE VIRTUAL TABLE ct1 USING transitive_closure(
-**       tablename='group',
-**       idcolumn='groupId',
-**       parentcolumn='parentId'
-**    );
-**
-** Such an instance of the transitive_closure virtual table would be
-** appropriate for walking a tree defined using a table like this, for example:
-**
-**    CREATE TABLE group(
-**      groupId INTEGER PRIMARY KEY,
-**      parentId INTEGER REFERENCES group
-**    );
-**    CREATE INDEX group_idx1 ON group(parentId);
-**
-** The group table above would presumably have other application-specific
-** fields.  The key point here is that rows of the group table form a
-** tree.  The purpose of the ct1 virtual table is to easily extract
-** branches of that tree.
-**
-** Once it has been created, the ct1 virtual table can be queried
-** as follows:
-**
-**    SELECT * FROM element
-**     WHERE element.groupId IN (SELECT id FROM ct1 WHERE root=?1);
-**
-** The above query will return all elements that are part of group ?1
-** or children of group ?1 or grand-children of ?1 and so forth for all
-** descendents of group ?1.  The same query can be formulated as a join:
-**
-**    SELECT element.* FROM element, ct1
-**     WHERE element.groupid=ct1.id
-**       AND ct1.root=?1;
-**
-** The depth of the transitive_closure (the number of generations of
-** parent/child relations to follow) can be limited by setting "depth"
-** column in the WHERE clause.  So, for example, the following query
-** finds only children and grandchildren but no further descendents:
-**
-**    SELECT element.* FROM element, ct1
-**     WHERE element.groupid=ct1.id
-**       AND ct1.root=?1
-**       AND ct1.depth<=2;
-**
-** The "ct1.depth<=2" term could be a strict equality "ct1.depth=2" in
-** order to find only the grandchildren of ?1, not ?1 itself or the
-** children of ?1.
-** 
-** The root=?1 term must be supplied in WHERE clause or else the query
-** of the ct1 virtual table will return an empty set.  The tablename,
-** idcolumn, and parentcolumn attributes can be overridden in the WHERE
-** clause if desired.  So, for example, the ct1 table could be repurposed
-** to find ancestors rather than descendents by inverting the roles of
-** the idcolumn and parentcolumn:
-**
-**    SELECT element.* FROM element, ct1
-**     WHERE element.groupid=ct1.id
-**       AND ct1.root=?1
-**       AND ct1.idcolumn='parentId'
-**       AND ct1.parentcolumn='groupId';
-**
-** Multiple calls to ct1 could be combined.  For example, the following
-** query finds all elements that "cousins" of groupId ?1.  That is to say
-** elements where the groupId is a grandchild of the grandparent of ?1.
-** (This definition of "cousins" also includes siblings and self.)
-**
-**    SELECT element.* FROM element, ct1
-**     WHERE element.groupId=ct1.id
-**       AND ct1.depth=2
-**       AND ct1.root IN (SELECT id FROM ct1
-**                         WHERE root=?1
-**                           AND depth=2
-**                           AND idcolumn='parentId'
-**                           AND parentcolumn='groupId');
-**
-** In our example, the group.groupId column is unique and thus the
-** subquery will return exactly one row.  For that reason, the IN
-** operator could be replaced by "=" to get the same result.  But
-** in the general case where the idcolumn is not unique, an IN operator
-** would be required for this kind of query.
-**
-** Note that because the tablename, idcolumn, and parentcolumn can
-** all be specified in the query, it is possible for an application
-** to define a single transitive_closure virtual table for use on lots
-** of different hierarchy tables.  One might say:
-**
-**     CREATE VIRTUAL TABLE temp.closure USING transitive_closure;
-**
-** As each database connection is being opened.  Then the application
-** would always have a "closure" virtual table handy to use for querying.
-**
-**    SELECT element.* FROM element, closure
-**     WHERE element.groupid=ct1.id
-**       AND closure.root=?1
-**       AND closure.tablename='group'
-**       AND closure.idname='groupId'
-**       AND closure.parentname='parentId';
-**
-** See the documentation at http://www.sqlite.org/loadext.html for information
-** on how to compile and use loadable extensions such as this one.

-*************************************************************************
-**
-** This file implements an eponymous virtual table that returns suggested
-** completions for a partial SQL input.
-**
-** Suggested usage:
-**
-**     SELECT DISTINCT candidate COLLATE nocase
-**       FROM completion($prefix,$wholeline)
-**      ORDER BY 1;
-**
-** The two query parameters are optional.  $prefix is the text of the
-** current word being typed and that is to be completed.  $wholeline is
-** the complete input line, used for context.
-**
-** The raw completion() table might return the same candidate multiple
-** times, for example if the same column name is used to two or more
-** tables.  And the candidates are returned in an arbitrary order.  Hence,
-** the DISTINCT and ORDER BY are recommended.
-**
-** This virtual table operates at the speed of human typing, and so there
-** is no attempt to make it fast.  Even a slow implementation will be much
-** faster than any human can type.

-******************************************************************************
-**
-** This file contains the implementation of an SQLite virtual table for
-** reading CSV files.
-**
-** Usage:
-**
-**    .load ./csv
-**    CREATE VIRTUAL TABLE temp.csv USING csv(filename=FILENAME);
-**    SELECT * FROM csv;
-**
-** The columns are named "c1", "c2", "c3", ... by default.  But the
-** application can define its own CREATE TABLE statement as an additional
-** parameter.  For example:
-**
-**    CREATE VIRTUAL TABLE temp.csv2 USING csv(
-**       filename = "../http.log",
-**       schema = "CREATE TABLE x(date,ipaddr,url,referrer,userAgent)"
-**    );
-**
-** Instead of specifying a file, the text of the CSV can be loaded using
-** the data= parameter.
-**
-** If the columns=N parameter is supplied, then the CSV file is assumed to have
-** N columns.  If the columns parameter is omitted, the CSV file is opened
-** as soon as the virtual table is constructed and the first row of the CSV
-** is read in order to count the tables.
-**
-** Some extra debugging features (used for testing virtual tables) are available
-** if this module is compiled with -DSQLITE_TEST.

-******************************************************************************
-**
-** This file implements a C-language subroutine that converts the content
-** of an SQLite database into UTF-8 text SQL statements that can be used
-** to exactly recreate the original database.  ROWID values are preserved.
-**
-** A prototype of the implemented subroutine is this:
-**
-**   int sqlite3_db_dump(
-**          sqlite3 *db,
-**          const char *zSchema,
-**          const char *zTable,
-**          void (*xCallback)(void*, const char*),
-**          void *pArg
-**   );
-**
-** The db parameter is the database connection.  zSchema is the schema within
-** that database which is to be dumped.  Usually the zSchema is "main" but
-** can also be "temp" or any ATTACH-ed database.  If zTable is not NULL, then
-** only the content of that one table is dumped.  If zTable is NULL, then all
-** tables are dumped.
-**
-** The generate text is passed to xCallback() in multiple calls.  The second
-** argument to xCallback() is a copy of the pArg parameter.  The first
-** argument is some of the output text that this routine generates.  The
-** signature to xCallback() is designed to make it compatible with fputs().
-**
-** The sqlite3_db_dump() subroutine returns SQLITE_OK on success or some error
-** code if it encounters a problem.
-**
-** If this file is compiled with -DDBDUMP_STANDALONE then a "main()" routine
-** is included so that this routine becomes a command-line utility.  The
-** command-line utility takes two or three arguments which are the name
-** of the database file, the schema, and optionally the table, forming the
-** first three arguments of a single call to the library routine.

-******************************************************************************
-**
-** This SQLite extension implements SQL functions readfile() and
-** writefile(), and eponymous virtual type "fsdir".
-**
-** WRITEFILE(FILE, DATA [, MODE [, MTIME]]):
-**
-**   If neither of the optional arguments is present, then this UDF
-**   function writes blob DATA to file FILE. If successful, the number
-**   of bytes written is returned. If an error occurs, NULL is returned.
-**
-**   If the first option argument - MODE - is present, then it must
-**   be passed an integer value that corresponds to a POSIX mode
-**   value (file type + permissions, as returned in the stat.st_mode
-**   field by the stat() system call). Three types of files may
-**   be written/created:
-**
-**     regular files:  (mode & 0170000)==0100000
-**     symbolic links: (mode & 0170000)==0120000
-**     directories:    (mode & 0170000)==0040000
-**
-**   For a directory, the DATA is ignored. For a symbolic link, it is
-**   interpreted as text and used as the target of the link. For a
-**   regular file, it is interpreted as a blob and written into the
-**   named file. Regardless of the type of file, its permissions are
-**   set to (mode & 0777) before returning.
-**
-**   If the optional MTIME argument is present, then it is interpreted
-**   as an integer - the number of seconds since the unix epoch. The
-**   modification-time of the target file is set to this value before
-**   returning.
-**
-**   If three or more arguments are passed to this function and an
-**   error is encountered, an exception is raised.
-**
-** READFILE(FILE):
-**
-**   Read and return the contents of file FILE (type blob) from disk.
-**
-** FSDIR:
-**
-**   Used as follows:
-**
-**     SELECT * FROM fsdir($path [, $dir]);
-**
-**   Parameter $path is an absolute or relative pathname. If the file that it
-**   refers to does not exist, it is an error. If the path refers to a regular
-**   file or symbolic link, it returns a single row. Or, if the path refers
-**   to a directory, it returns one row for the directory, and one row for each
-**   file within the hierarchy rooted at $path.
-**
-**   Each row has the following columns:
-**
-**     name:  Path to file or directory (text value).
-**     mode:  Value of stat.st_mode for directory entry (an integer).
-**     mtime: Value of stat.st_mtime for directory entry (an integer).
-**     data:  For a regular file, a blob containing the file data. For a
-**            symlink, a text value containing the text of the link. For a
-**            directory, NULL.
-**
-**   If a non-NULL value is specified for the optional $dir parameter and
-**   $path is a relative path, then $path is interpreted relative to $dir. 
-**   And the paths returned in the "name" column of the table are also 
-**   relative to directory $dir.

-*************************************************************************
-**
-** Code for a demonstration virtual table that generates variations
-** on an input word at increasing edit distances from the original.
-**
-** A fuzzer virtual table is created like this:
-**
-**     CREATE VIRTUAL TABLE f USING fuzzer(<fuzzer-data-table>);
-**
-** When it is created, the new fuzzer table must be supplied with the
-** name of a "fuzzer data table", which must reside in the same database
-** file as the new fuzzer table. The fuzzer data table contains the various
-** transformations and their costs that the fuzzer logic uses to generate
-** variations.
-**
-** The fuzzer data table must contain exactly four columns (more precisely,
-** the statement "SELECT * FROM <fuzzer_data_table>" must return records
-** that consist of four columns). It does not matter what the columns are
-** named. 
-**
-** Each row in the fuzzer data table represents a single character
-** transformation. The left most column of the row (column 0) contains an
-** integer value - the identifier of the ruleset to which the transformation
-** rule belongs (see "MULTIPLE RULE SETS" below). The second column of the
-** row (column 0) contains the input character or characters. The third 
-** column contains the output character or characters. And the fourth column
-** contains the integer cost of making the transformation. For example:
-**
-**    CREATE TABLE f_data(ruleset, cFrom, cTo, Cost);
-**    INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, '', 'a', 100);
-**    INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, 'b', '', 87);
-**    INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, 'o', 'oe', 38);
-**    INSERT INTO f_data(ruleset, cFrom, cTo, Cost) VALUES(0, 'oe', 'o', 40);
-**
-** The first row inserted into the fuzzer data table by the SQL script
-** above indicates that the cost of inserting a letter 'a' is 100.  (All 
-** costs are integers.  We recommend that costs be scaled so that the 
-** average cost is around 100.) The second INSERT statement creates a rule
-** saying that the cost of deleting a single letter 'b' is 87.  The third
-** and fourth INSERT statements mean that the cost of transforming a
-** single letter "o" into the two-letter sequence "oe" is 38 and that the
-** cost of transforming "oe" back into "o" is 40.
-**
-** The contents of the fuzzer data table are loaded into main memory when
-** a fuzzer table is first created, and may be internally reloaded by the
-** system at any subsequent time. Therefore, the fuzzer data table should be 
-** populated before the fuzzer table is created and not modified thereafter.
-** If you do need to modify the contents of the fuzzer data table, it is
-** recommended that the associated fuzzer table be dropped, the fuzzer data
-** table edited, and the fuzzer table recreated within a single transaction.
-** Alternatively, the fuzzer data table can be edited then the database
-** connection can be closed and reopened.
-**
-** Once it has been created, the fuzzer table can be queried as follows:
-**
-**    SELECT word, distance FROM f
-**     WHERE word MATCH 'abcdefg'
-**       AND distance<200;
-**
-** This first query outputs the string "abcdefg" and all strings that
-** can be derived from that string by appling the specified transformations.
-** The strings are output together with their total transformation cost
-** (called "distance") and appear in order of increasing cost.  No string
-** is output more than once.  If there are multiple ways to transform the
-** target string into the output string then the lowest cost transform is
-** the one that is returned.  In the example, the search is limited to 
-** strings with a total distance of less than 200.
-**
-** The fuzzer is a read-only table.  Any attempt to DELETE, INSERT, or
-** UPDATE on a fuzzer table will throw an error.
-**
-** It is important to put some kind of a limit on the fuzzer output.  This
-** can be either in the form of a LIMIT clause at the end of the query,
-** or better, a "distance<NNN" constraint where NNN is some number.  The
-** running time and memory requirement is exponential in the value of NNN 
-** so you want to make sure that NNN is not too big.  A value of NNN that
-** is about twice the average transformation cost seems to give good results.
-**
-** The fuzzer table can be useful for tasks such as spelling correction.
-** Suppose there is a second table vocabulary(w) where the w column contains
-** all correctly spelled words.   Let $word be a word you want to look up.
-**
-**   SELECT vocabulary.w FROM f, vocabulary
-**    WHERE f.word MATCH $word
-**      AND f.distance<=200
-**      AND f.word=vocabulary.w
-**    LIMIT 20
-**
-** The query above gives the 20 closest words to the $word being tested.
-** (Note that for good performance, the vocubulary.w column should be
-** indexed.)
-**
-** A similar query can be used to find all words in the dictionary that
-** begin with some prefix $prefix:
-**
-**   SELECT vocabulary.w FROM f, vocabulary

-**      AND f.distance<=200
-**      AND vocabulary.w BETWEEN f.word AND (f.word || x'F7BFBFBF')
-**    LIMIT 50
-**
-** This last query will show up to 50 words out of the vocabulary that
-** match or nearly match the $prefix.
-**
-** MULTIPLE RULE SETS
-**
-** Normally, the "ruleset" value associated with all character transformations
-** in the fuzzer data table is zero. However, if required, the fuzzer table
-** allows multiple rulesets to be defined. Each query uses only a single
-** ruleset. This allows, for example, a single fuzzer table to support 
-** multiple languages.
-**
-** By default, only the rules from ruleset 0 are used. To specify an 
-** alternative ruleset, a "ruleset = ?" expression must be added to the
-** WHERE clause of a SELECT, where ? is the identifier of the desired 
-** ruleset. For example:
-**
-**   SELECT vocabulary.w FROM f, vocabulary
-**    WHERE f.word MATCH $word
-**      AND f.distance<=200
-**      AND f.word=vocabulary.w
-**      AND f.ruleset=1  -- Specify the ruleset to use here
-**    LIMIT 20
-**
-** If no "ruleset = ?" constraint is specified in the WHERE clause, ruleset 
-** 0 is used.
-**
-** LIMITS
-**
-** The maximum ruleset number is 2147483647.  The maximum length of either
-** of the strings in the second or third column of the fuzzer data table
-** is 50 bytes.  The maximum cost on a rule is 1000.

-******************************************************************************
-**
-** This SQLite extension implements functions for the exact display

-**
-**   ieee754(X)
-**   ieee754(Y,Z)
-**
-** In the first form, the value X should be a floating-point number.
-** The function will return a string of the form 'ieee754(Y,Z)' where
-** Y and Z are integers such that X==Y*pow(2,Z).
-**
-** In the second form, Y and Z are integers which are the mantissa and
-** base-2 exponent of a new floating point number.  The function returns
-** a floating-point value equal to Y*pow(2,Z).
-**
-** Examples:
-**
-**     ieee754(2.0)       ->     'ieee754(2,0)'
-**     ieee754(45.25)     ->     'ieee754(181,-2)'
-**     ieee754(2, 0)      ->     2.0

-**
-** This is an in-memory VFS implementation.  The application supplies
-** a chunk of memory to hold the database file.
-**
-** Because there is place to store a rollback or wal journal, the database
-** must use one of journal_mode=MEMORY or journal_mode=NONE.
-**
-** USAGE:
-**
-**    sqlite3_open_v2("file:/whatever?ptr=0xf05538&sz=14336&max=65536", &db,
-**                    SQLITE_OPEN_READWRITE | SQLITE_OPEN_URI,
-**                    "memvfs");
-**
-** These are the query parameters:
-**
-**    ptr=          The address of the memory buffer that holds the database.
-**
-**    sz=           The current size the database file
-**
-**    maxsz=        The maximum size of the database.  In other words, the
-**                  amount of space allocated for the ptr= buffer.
-**
-**    freeonclose=  If true, then sqlite3_free() is called on the ptr=
-**                  value when the connection closes.
-**
-** The ptr= and sz= query parameters are required.  If maxsz= is omitted,
-** then it defaults to the sz= value.  Parameter values can be in either
-** decimal or hexadecimal.  The filename in the URI is ignored.

-******************************************************************************
-**
-** This file contains code to implement the next_char(A,T,F,W,C) SQL function.
-**
-** The next_char(A,T,F,W,C) function finds all valid "next" characters for
-** string A given the vocabulary in T.F.  If the W value exists and is a
-** non-empty string, then it is an SQL expression that limits the entries
-** in T.F that will be considered.  If C exists and is a non-empty string,
-** then it is the name of the collating sequence to use for comparison.  If
-** 
-** Only the first three arguments are required.  If the C parameter is 
-** omitted or is NULL or is an empty string, then the default collating 
-** sequence of T.F is used for comparision.  If the W parameter is omitted
-** or is NULL or is an empty string, then no filtering of the output is
-** done.
-**
-** The T.F column should be indexed using collation C or else this routine
-** will be quite slow.
-**
-** For example, suppose an application has a dictionary like this:
-**
-**   CREATE TABLE dictionary(word TEXT UNIQUE);
-**
-** Further suppose that for user keypad entry, it is desired to disable
-** (gray out) keys that are not valid as the next character.  If the
-** the user has previously entered (say) 'cha' then to find all allowed
-** next characters (and thereby determine when keys should not be grayed
-** out) run the following query:
-**
-**   SELECT next_char('cha','dictionary','word');
-**
-** IMPLEMENTATION NOTES:
-**
-** The next_char function is implemented using recursive SQL that makes
-** use of the table name and column name as part of a query.  If either
-** the table name or column name are keywords or contain special characters,
-** then they should be escaped.  For example:
-**
-**   SELECT next_char('cha','[dictionary]','[word]');
-**
-** This also means that the table name can be a subquery:
-**
-**   SELECT next_char('cha','(SELECT word AS w FROM dictionary)','w');

-******************************************************************************
-**
-** This file contains code to implement the sqlite3_normalize() function.
-**
-**    char *sqlite3_normalize(const char *zSql);
-**
-** This function takes an SQL string as input and returns a "normalized"
-** version of that string in memory obtained from sqlite3_malloc64().  The
-** caller is responsible for ensuring that the returned memory is freed.
-**
-** If a memory allocation error occurs, this routine returns NULL.
-**
-** The normalization consists of the following transformations:
-**
-**   (1)  Convert every literal (string, blob literal, numeric constant,
-**        or "NULL" constant) into a ?
-**
-**   (2)  Remove all superfluous whitespace, including comments.  Change
-**        all required whitespace to a single space character.
-**
-**   (3)  Lowercase all ASCII characters.
-**
-**   (4)  If an IN or NOT IN operator is followed by a list of 1 or more
-**        values, convert that list into "(?,?,?)".
-**
-** The purpose of normalization is two-fold:
-**
-**   (1)  Sanitize queries by removing potentially private or sensitive
-**        information contained in literals.
-**
-**   (2)  Identify structurally identical queries by comparing their
-**        normalized forms.
-**
-** Command-Line Utility
-** --------------------
-**
-** This file also contains code for a command-line utility that converts
-** SQL queries in text files into their normalized forms.  To build the
-** command-line program, compile this file with -DSQLITE_NORMALIZE_CLI
-** and link it against the SQLite library.

-** Implementation note:

-** Much of the tokenizer logic is copied out of the tokenize.c source file

-** The following 256 byte lookup table is used to support SQLites built-in
-** equivalents to the following standard library functions:
-**
-**   isspace()                        0x01
-**   isalpha()                        0x02
-**   isdigit()                        0x04
-**   isalnum()                        0x06
-**   isxdigit()                       0x08
-**   toupper()                        0x20
-**   SQLite identifier character      0x40
-**   Quote character                  0x80
-**
-** Bit 0x20 is set if the mapped character requires translation to upper
-** case. i.e. if the character is a lower-case ASCII character.
-** If x is a lower-case ASCII character, then its upper-case equivalent
-** is (x - 0x20). Therefore toupper() can be implemented as:
-**
-**   (x & ~(map[x]&0x20))
-**
-** The equivalent of tolower() is implemented using the sqlite3UpperToLower[]
-** array. tolower() is used more often than toupper() by SQLite.
-**
-** Bit 0x40 is set if the character is non-alphanumeric and can be used in an 
-** SQLite identifier.  Identifiers are alphanumerics, "_", "$", and any
-** non-ASCII UTF character. Hence the test for whether or not a character is
-** part of an identifier is 0x46.

-******************************************************************************
-**
-** This file contains code to implement the percentile(Y,P) SQL function
-** as described below:
-**
-**   (1)  The percentile(Y,P) function is an aggregate function taking
-**        exactly two arguments.
-**
-**   (2)  If the P argument to percentile(Y,P) is not the same for every
-**        row in the aggregate then an error is thrown.  The word "same"
-**        in the previous sentence means that the value differ by less
-**        than 0.001.
-**
-**   (3)  If the P argument to percentile(Y,P) evaluates to anything other
-**        than a number in the range of 0.0 to 100.0 inclusive then an
-**        error is thrown.
-**
-**   (4)  If any Y argument to percentile(Y,P) evaluates to a value that
-**        is not NULL and is not numeric then an error is thrown.
-**
-**   (5)  If any Y argument to percentile(Y,P) evaluates to plus or minus
-**        infinity then an error is thrown.  (SQLite always interprets NaN
-**        values as NULL.)
-**
-**   (6)  Both Y and P in percentile(Y,P) can be arbitrary expressions,
-**        including CASE WHEN expressions.
-**
-**   (7)  The percentile(Y,P) aggregate is able to handle inputs of at least
-**        one million (1,000,000) rows.
-**
-**   (8)  If there are no non-NULL values for Y, then percentile(Y,P)
-**        returns NULL.
-**
-**   (9)  If there is exactly one non-NULL value for Y, the percentile(Y,P)
-**        returns the one Y value.
-**
-**  (10)  If there N non-NULL values of Y where N is two or more and
-**        the Y values are ordered from least to greatest and a graph is
-**        drawn from 0 to N-1 such that the height of the graph at J is
-**        the J-th Y value and such that straight lines are drawn between
-**        adjacent Y values, then the percentile(Y,P) function returns
-**        the height of the graph at P*(N-1)/100.
-**
-**  (11)  The percentile(Y,P) function always returns either a floating
-**        point number or NULL.
-**
-**  (12)  The percentile(Y,P) is implemented as a single C99 source-code
-**        file that compiles into a shared-library or DLL that can be loaded
-**        into SQLite using the sqlite3_load_extension() interface.

-******************************************************************************
-**
-** The code in this file implements a compact but reasonably
-** efficient regular-expression matcher for posix extended regular
-** expressions against UTF8 text.
-**
-** This file is an SQLite extension.  It registers a single function
-** named "regexp(A,B)" where A is the regular expression and B is the
-** string to be matched.  By registering this function, SQLite will also
-** then implement the "B regexp A" operator.  Note that with the function
-** the regular expression comes first, but with the operator it comes
-** second.
-**
-**  The following regular expression syntax is supported:
-**
-**     X*      zero or more occurrences of X
-**     X+      one or more occurrences of X
-**     X?      zero or one occurrences of X
-**     X{p,q}  between p and q occurrences of X
-**     (X)     match X
-**     X|Y     X or Y
-**     ^X      X occurring at the beginning of the string
-**     X$      X occurring at the end of the string
-**     .       Match any single character
-**     \c      Character c where c is one of \{}()[]|*+?.
-**     \c      C-language escapes for c in afnrtv.  ex: \t or \n
-**     \uXXXX  Where XXXX is exactly 4 hex digits, unicode value XXXX
-**     \xXX    Where XX is exactly 2 hex digits, unicode value XX
-**     [abc]   Any single character from the set abc
-**     [^abc]  Any single character not in the set abc
-**     [a-z]   Any single character in the range a-z
-**     [^a-z]  Any single character not in the range a-z
-**     \b      Word boundary
-**     \w      Word character.  [A-Za-z0-9_]
-**     \W      Non-word character
-**     \d      Digit
-**     \D      Non-digit
-**     \s      Whitespace character
-**     \S      Non-whitespace character
-**
-** A nondeterministic finite automaton (NFA) is used for matching, so the
-** performance is bounded by O(N*M) where N is the size of the regular
-** expression and M is the size of the input string.  The matcher never
-** exhibits exponential behavior.  Note that the X{p,q} operator expands
-** to p copies of X following by q-p copies of X? and that the size of the
-** regular expression in the O(N*M) performance bound is computed after
-** this expansion.

-** value that is passed through into a C-language variable.  The address of

-** value retrieved, atomically, using a single statement:
-**
-**    UPDATE counterTab SET cnt=remember(cnt,$PTR)+1 WHERE id=$ID
-**
-** Prepare the above statement once.  Then to use it, bind the address
-** of the output variable to $PTR using sqlite3_bind_pointer() with a
-** pointer type of "carray" and bind the id of the counter to $ID and
-** run the prepared statement.
-**
-** This implementation of the remember() function uses a "carray"
-** pointer so that it can share pointers with the carray() extension.

-******************************************************************************
-**
-** This file implements a utility function (and a utility program) that
-** makes a copy of an SQLite database while simultaneously zeroing out all
-** deleted content.
-**
-** Normally (when PRAGMA secure_delete=OFF, which is the default) when SQLite
-** deletes content, it does not overwrite the deleted content but rather marks
-** the region of the file that held that content as being reusable.  This can
-** cause deleted content to recoverable from the database file.  This stale
-** content is removed by the VACUUM command, but VACUUM can be expensive for
-** large databases.  When in PRAGMA secure_delete=ON mode, the deleted content
-** is zeroed, but secure_delete=ON has overhead as well.
-**
-** This utility attempts to make a copy of a complete SQLite database where
-** all of the deleted content is zeroed out in the copy, and it attempts to
-** do so while being faster than running VACUUM.
-**
-** Usage:
-**
-**   int sqlite3_scrub_backup(
-**       const char *zSourceFile,   // Source database filename
-**       const char *zDestFile,     // Destination database filename
-**       char **pzErrMsg            // Write error message here
-**   );
-**
-** Simply call the API above specifying the filename of the source database
-** and the name of the backup copy.  The source database must already exist
-** and can be in active use. (A read lock is held during the backup.)  The
-** destination file should not previously exist.  If the pzErrMsg parameter
-** is non-NULL and if an error occurs, then an error message might be written
-** into memory obtained from sqlite3_malloc() and *pzErrMsg made to point to
-** that error message.  But if the error is an OOM, the error might not be
-** reported.  The routine always returns non-zero if there is an error.
-**
-** If compiled with -DSCRUB_STANDALONE then a main() procedure is added and
-** this file becomes a standalone program that can be run as follows:

-*************************************************************************
-**
-** This file demonstrates how to create a table-valued-function using
-** a virtual table.  This demo implements the generate_series() function
-** which gives similar results to the eponymous function in PostgreSQL.
-** Examples:
-**
-**      SELECT * FROM generate_series(0,100,5);
-**
-** The query above returns integers from 0 through 100 counting by steps
-** of 5.
-**
-**      SELECT * FROM generate_series(0,100);
-**
-** Integers from 0 through 100 with a step size of 1.
-**
-**      SELECT * FROM generate_series(20) LIMIT 10;
-**
-** Integers 20 through 29.
-**
-** HOW IT WORKS
-**
-** The generate_series "function" is really a virtual table with the
-** following schema:
-**
-**     CREATE TABLE generate_series(
-**       value,
-**       start HIDDEN,
-**       stop HIDDEN,
-**       step HIDDEN
-**     );
-**
-** Function arguments in queries against this virtual table are translated
-** into equality constraints against successive hidden columns.  In other
-** words, the following pairs of queries are equivalent to each other:
-**
-**    SELECT * FROM generate_series(0,100,5);
-**    SELECT * FROM generate_series WHERE start=0 AND stop=100 AND step=5;
-**
-**    SELECT * FROM generate_series(0,100);
-**    SELECT * FROM generate_series WHERE start=0 AND stop=100;
-**
-**    SELECT * FROM generate_series(20) LIMIT 10;
-**    SELECT * FROM generate_series WHERE start=20 LIMIT 10;
-**
-** The generate_series virtual table implementation leaves the xCreate method
-** set to NULL.  This means that it is not possible to do a CREATE VIRTUAL
-** TABLE command with "generate_series" as the USING argument.  Instead, there
-** is a single generate_series virtual table that is always available without
-** having to be created first.
-**
-** The xBestIndex method looks for equality constraints against the hidden
-** start, stop, and step columns, and if present, it uses those constraints
-** to bound the sequence of generated values.  If the equality constraints
-** are missing, it uses 0 for start, 4294967295 for stop, and 1 for step.
-** xBestIndex returns a small cost when both start and stop are available,
-** and a very large cost if either start or stop are unavailable.  This
-** encourages the query planner to order joins such that the bounds of the
-** series are well-defined.

-** This SQLite extension implements a functions that compute SHA1 hashes.
-** Two SQL functions are implemented:
-**
-**     sha3(X,SIZE)
-**     sha3_query(Y,SIZE)
-**
-** The sha3(X) function computes the SHA3 hash of the input X, or NULL if
-** X is NULL.
-**
-** The sha3_query(Y) function evalutes all queries in the SQL statements of Y
-** and returns a hash of their results.
-**
-** The SIZE argument is optional.  If omitted, the SHA3-256 hash algorithm
-** is used.  If SIZE is included it must be one of the integers 224, 256,
-** 384, or 512, to determine SHA3 hash variant that is computed.

-** the size of that text.  The SQL text is UTF-8.  A single R character
-** occurs before the start of each row.  N means a NULL value.
-** I mean an 8-byte little-endian integer <int>.  F is a floating point
-** number with an 8-byte little-endian IEEE floating point value <ieee-float>.
-** B means blobs of <size> bytes.  T means text rendered as <size>
-** bytes of UTF-8.  The <n> and <size> values are expressed as an ASCII
-** text integers.
-**
-** For each SQL statement in the X input, there is one S segment.  Each
-** S segment is followed by zero or more R segments, one for each row in the
-** result set.  After each R, there are one or more N, I, F, B, or T segments,

-*************************************************************************
-**
-** This file implements a template virtual-table.
-** Developers can make a copy of this file as a baseline for writing
-** new virtual tables and/or table-valued functions.
-**
-** Steps for writing a new virtual table implementation:
-**
-**     (1)  Make a copy of this file.  Perhaps call it "mynewvtab.c"
-**
-**     (2)  Replace this header comment with something appropriate for
-**          the new virtual table
-**
-**     (3)  Change every occurrence of "templatevtab" to some other string
-**          appropriate for the new virtual table.  Ideally, the new string
-**          should be the basename of the source file: "mynewvtab".  Also
-**          globally change "TEMPLATEVTAB" to "MYNEWVTAB".
-**
-**     (4)  Run a test compilation to make sure the unmodified virtual
-**          table works.
-**
-**     (5)  Begin making incremental changes, testing as you go, to evolve
-**          the new virtual table to do what you want it to do.
-**
-** This template is minimal, in the sense that it uses only the required
-** methods on the sqlite3_module object.  As a result, templatevtab is
-** a read-only and eponymous-only table.  Those limitation can be removed
-** by adding new methods.
-**
-** This template implements an eponymous-only virtual table with a rowid and
-** two columns named "a" and "b".  The table as 10 rows with fixed integer
-** values. Usage example:
-**
-**     SELECT rowid, a, b FROM templatevtab;

-** The author disclaims copyright to this source code.  In place of
-** a legal notice, here is a blessing:

-**
-*************************************************************************
-**
-** This file contains the implementation of the "unionvtab" and "swarmvtab"
-** virtual tables. These modules provide read-only access to multiple tables,
-** possibly in multiple database files, via a single database object.
-** The source tables must have the following characteristics:
-**
-**   * They must all be rowid tables (not VIRTUAL or WITHOUT ROWID
-**     tables or views).
-**
-**   * Each table must have the same set of columns, declared in
-**     the same order and with the same declared types.
-**
-**   * The tables must not feature a user-defined column named "_rowid_".
-**
-**   * Each table must contain a distinct range of rowid values.
-**
-** The difference between the two virtual table modules is that for 
-** "unionvtab", all source tables must be located in the main database or
-** in databases ATTACHed to the main database by the user. For "swarmvtab",
-** the tables may be located in any database file on disk. The "swarmvtab"
-** implementation takes care of opening and closing database files
-** automatically.
-**
-** UNIONVTAB
-**
-**   A "unionvtab" virtual table is created as follows:
-**
-**     CREATE VIRTUAL TABLE <name> USING unionvtab(<sql-statement>);
-**
-**   The implementation evalutes <sql statement> whenever a unionvtab virtual
-**   table is created or opened. It should return one row for each source
-**   database table. The four columns required of each row are:
-**
-**     1. The name of the database containing the table ("main" or "temp" or
-**        the name of an attached database). Or NULL to indicate that all
-**        databases should be searched for the table in the usual fashion.
-**
-**     2. The name of the database table.
-**
-**     3. The smallest rowid in the range of rowids that may be stored in the
-**        database table (an integer).
-**
-**     4. The largest rowid in the range of rowids that may be stored in the
-**        database table (an integer).
-**
-** SWARMVTAB
-**
-**  LEGACY SYNTAX:
-**
-**   A "swarmvtab" virtual table is created similarly to a unionvtab table:
-**
-**     CREATE VIRTUAL TABLE <name>
-**      USING swarmvtab(<sql-statement>, <callback>);
-**
-**   The difference is that for a swarmvtab table, the first column returned
-**   by the <sql statement> must return a path or URI that can be used to open
-**   the database file containing the source table.  The <callback> option
-**   is optional.  If included, it is the name of an application-defined
-**   SQL function that is invoked with the URI of the file, if the file
-**   does not already exist on disk when required by swarmvtab.
-**
-**  NEW SYNTAX:
-**
-**   Using the new syntax, a swarmvtab table is created with:
-**
-**      CREATE VIRTUAL TABLE <name> USING swarmvtab(
-**        <sql-statement> [, <options>]
-**      );
-**
-**   where valid <options> are:
-**
-**      missing=<udf-function-name>
-**      openclose=<udf-function-name>
-**      maxopen=<integer>
-**      <sql-parameter>=<text-value>
-**
-**   The <sql-statement> must return the same 4 columns as for a swarmvtab
-**   table in legacy mode. However, it may also return a 5th column - the
-**   "context" column. The text value returned in this column is not used
-**   at all by the swarmvtab implementation, except that it is passed as
-**   an additional argument to the two UDF functions that may be invoked
-**   (see below).
-**
-**   The "missing" option, if present, specifies the name of an SQL UDF
-**   function to be invoked if a database file is not already present on
-**   disk when required by swarmvtab. If the <sql-statement> did not provide
-**   a context column, it is invoked as:
-**
-**     SELECT <missing-udf>(<database filename/uri>);
-**
-**   Or, if there was a context column:
-**
-**     SELECT <missing-udf>(<database filename/uri>, <context>);
-**
-**   The "openclose" option may also specify a UDF function. This function
-**   is invoked right before swarmvtab opens a database, and right after
-**   it closes one. The first argument - or first two arguments, if
-**   <sql-statement> supplied the context column - is the same as for
-**   the "missing" UDF. Following this, the UDF is passed integer value
-**   0 before a db is opened, and 1 right after it is closed. If both
-**   a missing and openclose UDF is supplied, the application should expect
-**   the following sequence of calls (for a single database):
-**
-**      SELECT <openclose-udf>(<db filename>, <context>, 0);
-**      if( db not already on disk ){
-**          SELECT <missing-udf>(<db filename>, <context>);
-**      }
-**      ... swarmvtab uses database ...
-**      SELECT <openclose-udf>(<db filename>, <context>, 1);
-**
-**   The "maxopen" option is used to configure the maximum number of
-**   database files swarmvtab will hold open simultaneously (default 9).
-**
-**   If an option name begins with a ":" character, then it is assumed
-**   to be an SQL parameter. In this case, the specified text value is
-**   bound to the same variable of the <sql-statement> before it is 
-**   executed. It is an error of the named SQL parameter does not exist.
-**   For example:
-**
-**     CREATE VIRTUAL TABLE swarm USING swarmvtab(
-**       'SELECT :path || localfile, tbl, min, max FROM swarmdir',
-**       :path='/home/user/databases/'
-**       missing='missing_func'
-**     );

-** This file contains the implementation of an SQLite vfs wrapper for
-** unix that generates per-database log files of all disk activity.
-*/
-
-/*
-** This module contains code for a wrapper VFS that causes a log of
-** most VFS calls to be written into a file on disk.
-**
-** Each database connection creates a separate log file in the same
-** directory as the original database and named after the original
-** database.  A unique suffix is added to avoid name collisions.  
-** Separate log files are used so that concurrent processes do not
-** try to write log operations to the same file at the same instant, 
-** resulting in overwritten or comingled log text.
-**
-** Each individual log file records operations by a single database
-** connection on both the original database and its associated rollback
-** journal.
-**
-** The log files are in the comma-separated-value (CSV) format.  The
-** log files can be imported into an SQLite database using the ".import"
-** command of the SQLite command-line shell for analysis.
-**
-** One technique for using this module is to append the text of this
-** module to the end of a standard "sqlite3.c" amalgamation file then
-** add the following compile-time options:
-**
-**     -DSQLITE_EXTRA_INIT=sqlite3_register_vfslog
-**     -DSQLITE_USE_FCNTL_TRACE
-**
-** The first compile-time option causes the sqlite3_register_vfslog()
-** function, defined below, to be invoked when SQLite is initialized.
-** That causes this custom VFS to become the default VFS for all
-** subsequent connections.  The SQLITE_USE_FCNTL_TRACE option causes
-** the SQLite core to issue extra sqlite3_file_control() operations
-** with SQLITE_FCNTL_TRACE to give some indication of what is going
-** on in the core.

-SQLITE_EXTENSION_INIT1
-
-/*
-** This module contains code for a wrapper VFS that cause stats for
-** most VFS calls to be recorded.
-**
-** To use this module, first compile it as a loadable extension.  See
-** https://www.sqlite.org/loadext.html#build for compilations instructions.
-**
-** After compliing, load this extension, then open database connections to be
-** measured.  Query usages status using the vfsstat virtual table:
-**
-**         SELECT * FROM vfsstat;
-**
-** Reset counters using UPDATE statements against vfsstat:
-**
-**         UPDATE vfsstat SET count=0;
-**
-** EXAMPLE SCRIPT:
-**
-**      .load ./vfsstat
-**      .open test.db
-**      DROP TABLE IF EXISTS t1;
-**      CREATE TABLE t1(x,y);
-**      INSERT INTO t1 VALUES(123, randomblob(5000));
-**      CREATE INDEX t1x ON t1(x);
-**      DROP TABLE t1;
-**      VACUUM;
-**      SELECT * FROM vfsstat WHERE count>0;
-**
-** LIMITATIONS:
-** 
-** This module increments counters without using mutex protection.  So if
-** two or more threads try to use this module at the same time, race conditions
-** may occur which mess up the counts.  This is harmless, other than giving
-** incorrect statistics.

-*************************************************************************
-**
-**
-** OVERVIEW 
-**
-**  The RBU extension requires that the RBU update be packaged as an
-**  SQLite database. The tables it expects to find are described in
-**  sqlite3rbu.h.  Essentially, for each table xyz in the target database
-**  that the user wishes to write to, a corresponding data_xyz table is
-**  created in the RBU database and populated with one row for each row to
-**  update, insert or delete from the target table.
-** 
-**  The update proceeds in three stages:
-** 
-**  1) The database is updated. The modified database pages are written
-**     to a *-oal file. A *-oal file is just like a *-wal file, except
-**     that it is named "<database>-oal" instead of "<database>-wal".
-**     Because regular SQLite clients do not look for file named
-**     "<database>-oal", they go on using the original database in
-**     rollback mode while the *-oal file is being generated.
-** 
-**     During this stage RBU does not update the database by writing
-**     directly to the target tables. Instead it creates "imposter"
-**     tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses
-**     to update each b-tree individually. All updates required by each
-**     b-tree are completed before moving on to the next, and all
-**     updates are done in sorted key order.
-** 
-**  2) The "<database>-oal" file is moved to the equivalent "<database>-wal"
-**     location using a call to rename(2). Before doing this the RBU
-**     module takes an EXCLUSIVE lock on the database file, ensuring
-**     that there are no other active readers.
-** 
-**     Once the EXCLUSIVE lock is released, any other database readers
-**     detect the new *-wal file and read the database in wal mode. At
-**     this point they see the new version of the database - including
-**     the updates made as part of the RBU update.
-** 
-**  3) The new *-wal file is checkpointed. This proceeds in the same way 
-**     as a regular database checkpoint, except that a single frame is
-**     checkpointed each time sqlite3rbu_step() is called. If the RBU
-**     handle is closed before the entire *-wal file is checkpointed,
-**     the checkpoint progress is saved in the RBU database and the
-**     checkpoint can be resumed by another RBU client at some point in
-**     the future.
-**
-** POTENTIAL PROBLEMS
-** 
-**  The rename() call might not be portable. And RBU is not currently
-**  syncing the directory after renaming the file.
-**
-**  When state is saved, any commit to the *-oal file and the commit to
-**  the RBU update database are not atomic. So if the power fails at the
-**  wrong moment they might get out of sync. As the main database will be
-**  committed before the RBU update database this will likely either just
-**  pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE
-**  constraint violations).
-**
-**  If some client does modify the target database mid RBU update, or some
-**  other error occurs, the RBU extension will keep throwing errors. It's
-**  not really clear how to get out of this state. The system could just
-**  by delete the RBU update database and *-oal file and have the device
-**  download the update again and start over.
-**
-**  At present, for an UPDATE, both the new.* and old.* records are
-**  collected in the rbu_xyz table. And for both UPDATEs and DELETEs all
-**  fields are collected.  This means we're probably writing a lot more
-**  data to disk when saving the state of an ongoing update to the RBU
-**  update database than is strictly necessary.

-/**************************************************************************
-** Beginning of RBU VFS shim methods. The VFS shim modifies the behaviour
-** of a standard VFS in the following ways:
-**
-** 1. Whenever the first page of a main database file is read or 
-**    written, the value of the change-counter cookie is stored in
-**    rbu_file.iCookie. Similarly, the value of the "write-version"
-**    database header field is stored in rbu_file.iWriteVer. This ensures
-**    that the values are always trustworthy within an open transaction.
-**
-** 2. Whenever an SQLITE_OPEN_WAL file is opened, the (rbu_file.pWalFd)
-**    member variable of the associated database file descriptor is set
-**    to point to the new file. A mutex protected linked list of all main 
-**    db fds opened using a particular RBU VFS is maintained at 
-**    rbu_vfs.pMain to facilitate this.
-**
-** 3. Using a new file-control "SQLITE_FCNTL_RBU", a main db rbu_file 
-**    object can be marked as the target database of an RBU update. This
-**    turns on the following extra special behaviour:
-**
-** 3a. If xAccess() is called to check if there exists a *-wal file 
-**     associated with an RBU target database currently in RBU_STAGE_OAL
-**     stage (preparing the *-oal file), the following special handling
-**     applies:
-**
-**      * if the *-wal file does exist, return SQLITE_CANTOPEN. An RBU
-**        target database may not be in wal mode already.
-**
-**      * if the *-wal file does not exist, set the output parameter to
-**        non-zero (to tell SQLite that it does exist) anyway.
-**
-**     Then, when xOpen() is called to open the *-wal file associated with
-**     the RBU target in RBU_STAGE_OAL stage, instead of opening the *-wal
-**     file, the rbu vfs opens the corresponding *-oal file instead. 
-**
-** 3b. The *-shm pages returned by xShmMap() for a target db file in
-**     RBU_STAGE_OAL mode are actually stored in heap memory. This is to
-**     avoid creating a *-shm file on disk. Additionally, xShmLock() calls
-**     are no-ops on target database files in RBU_STAGE_OAL mode. This is
-**     because assert() statements in some VFS implementations fail if 
-**     xShmLock() is called before xShmMap().
-**
-** 3c. If an EXCLUSIVE lock is attempted on a target database file in any
-**     mode except RBU_STAGE_DONE (all work completed and checkpointed), it 
-**     fails with an SQLITE_BUSY error. This is to stop RBU connections
-**     from automatically checkpointing a *-wal (or *-oal) file from within
-**     sqlite3_close().
-**
-** 3d. In RBU_STAGE_CAPTURE mode, all xRead() calls on the wal file, and
-**     all xWrite() calls on the target database file perform no IO. 
-**     Instead the frame and page numbers that would be read and written
-**     are recorded. Additionally, successful attempts to obtain exclusive
-**     xShmLock() WRITER, CHECKPOINTER and READ0 locks on the target 
-**     database file are recorded. xShmLock() calls to unlock the same
-**     locks are no-ops (so that once obtained, these locks are never
-**     relinquished). Finally, calls to xSync() on the target database
-**     file fail with SQLITE_INTERNAL errors.

-** SUMMARY
-**
-** Writing a transaction containing a large number of operations on 
-** b-tree indexes that are collectively larger than the available cache
-** memory can be very inefficient. 
-**
-** The problem is that in order to update a b-tree, the leaf page (at least)
-** containing the entry being inserted or deleted must be modified. If the
-** working set of leaves is larger than the available cache memory, then a 
-** single leaf that is modified more than once as part of the transaction 
-** may be loaded from or written to the persistent media multiple times.
-** Additionally, because the index updates are likely to be applied in
-** random order, access to pages within the database is also likely to be in 
-** random order, which is itself quite inefficient.
-**
-** One way to improve the situation is to sort the operations on each index
-** by index key before applying them to the b-tree. This leads to an IO
-** pattern that resembles a single linear scan through the index b-tree,
-** and all but guarantees each modified leaf page is loaded and stored 
-** exactly once. SQLite uses this trick to improve the performance of
-** CREATE INDEX commands. This extension allows it to be used to improve
-** the performance of large transactions on existing databases.
-**
-** Additionally, this extension allows the work involved in writing the 
-** large transaction to be broken down into sub-transactions performed 
-** sequentially by separate processes. This is useful if the system cannot 
-** guarantee that a single update process will run for long enough to apply 
-** the entire update, for example because the update is being applied on a 
-** mobile device that is frequently rebooted. Even after the writer process 
-** has committed one or more sub-transactions, other database clients continue
-** to read from the original database snapshot. In other words, partially 
-** applied transactions are not visible to other clients. 
-**
-** "RBU" stands for "Resumable Bulk Update". As in a large database update
-** transmitted via a wireless network to a mobile device. A transaction
-** applied using this extension is hence refered to as an "RBU update".
-**
-**
-** LIMITATIONS
-**
-** An "RBU update" transaction is subject to the following limitations:
-**
-**   * The transaction must consist of INSERT, UPDATE and DELETE operations
-**     only.
-**
-**   * INSERT statements may not use any default values.
-**
-**   * UPDATE and DELETE statements must identify their target rows by 
-**     non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY
-**     KEY fields may not be updated or deleted. If the table being written 
-**     has no PRIMARY KEY, affected rows must be identified by rowid.
-**
-**   * UPDATE statements may not modify PRIMARY KEY columns.
-**

-** PREPARATION
-**
-** An "RBU update" is stored as a separate SQLite database. A database
-** containing an RBU update is an "RBU database". For each table in the 
-** target database to be updated, the RBU database should contain a table
-** named "data_<target name>" containing the same set of columns as the
-** target table, and one more - "rbu_control". The data_% table should 
-** have no PRIMARY KEY or UNIQUE constraints, but each column should have
-** the same type as the corresponding column in the target database.
-** The "rbu_control" column should have no type at all. For example, if
-** the target database contains:
-**
-**   CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE);
-**
-** Then the RBU database should contain:
-**
-**   CREATE TABLE data_t1(a INTEGER, b TEXT, c, rbu_control);
-**
-** The order of the columns in the data_% table does not matter.
-**
-** Instead of a regular table, the RBU database may also contain virtual
-** tables or view named using the data_<target> naming scheme. 
-**
-** Instead of the plain data_<target> naming scheme, RBU database tables 
-** may also be named data<integer>_<target>, where <integer> is any sequence
-** of zero or more numeric characters (0-9). This can be significant because
-** tables within the RBU database are always processed in order sorted by 
-** name. By judicious selection of the <integer> portion of the names
-** of the RBU tables the user can therefore control the order in which they
-** are processed. This can be useful, for example, to ensure that "external
-** content" FTS4 tables are updated before their underlying content tables.
-**
-** If the target database table is a virtual table or a table that has no
-** PRIMARY KEY declaration, the data_% table must also contain a column 
-** named "rbu_rowid". This column is mapped to the tables implicit primary 
-** key column - "rowid". Virtual tables for which the "rowid" column does 
-** not function like a primary key value cannot be updated using RBU. For 
-** example, if the target db contains either of the following:
-**
-**   CREATE VIRTUAL TABLE x1 USING fts3(a, b);
-**   CREATE TABLE x1(a, b)
-**
-** then the RBU database should contain:
-**
-**   CREATE TABLE data_x1(a, b, rbu_rowid, rbu_control);
-**
-** All non-hidden columns (i.e. all columns matched by "SELECT *") of the
-** target table must be present in the input table. For virtual tables,
-** hidden columns are optional - they are updated by RBU if present in
-** the input table, or not otherwise. For example, to write to an fts4
-** table with a hidden languageid column such as:
-**
-**   CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid');
-**
-** Either of the following input table schemas may be used:
-**
-**   CREATE TABLE data_ft1(a, b, langid, rbu_rowid, rbu_control);
-**   CREATE TABLE data_ft1(a, b, rbu_rowid, rbu_control);
-**
-** For each row to INSERT into the target database as part of the RBU 
-** update, the corresponding data_% table should contain a single record
-** with the "rbu_control" column set to contain integer value 0. The
-** other columns should be set to the values that make up the new record 
-** to insert. 
-**
-** If the target database table has an INTEGER PRIMARY KEY, it is not 
-** possible to insert a NULL value into the IPK column. Attempting to 
-** do so results in an SQLITE_MISMATCH error.
-**
-** For each row to DELETE from the target database as part of the RBU 
-** update, the corresponding data_% table should contain a single record
-** with the "rbu_control" column set to contain integer value 1. The
-** real primary key values of the row to delete should be stored in the
-** corresponding columns of the data_% table. The values stored in the
-** other columns are not used.
-**
-** For each row to UPDATE from the target database as part of the RBU 
-** update, the corresponding data_% table should contain a single record
-** with the "rbu_control" column set to contain a value of type text.
-** The real primary key values identifying the row to update should be 
-** stored in the corresponding columns of the data_% table row, as should
-** the new values of all columns being update. The text value in the 
-** "rbu_control" column must contain the same number of characters as
-** there are columns in the target database table, and must consist entirely
-** of 'x' and '.' characters (or in some special cases 'd' - see below). For 
-** each column that is being updated, the corresponding character is set to
-** 'x'. For those that remain as they are, the corresponding character of the
-** rbu_control value should be set to '.'. For example, given the tables 
-** above, the update statement:
-**
-**   UPDATE t1 SET c = 'usa' WHERE a = 4;
-**
-** is represented by the data_t1 row created by:
-**
-**   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..x');
-**
-** Instead of an 'x' character, characters of the rbu_control value specified
-** for UPDATEs may also be set to 'd'. In this case, instead of updating the
-** target table with the value stored in the corresponding data_% column, the
-** user-defined SQL function "rbu_delta()" is invoked and the result stored in
-** the target table column. rbu_delta() is invoked with two arguments - the
-** original value currently stored in the target table column and the 
-** value specified in the data_xxx table.
-**
-** For example, this row:
-**
-**   INSERT INTO data_t1(a, b, c, rbu_control) VALUES(4, NULL, 'usa', '..d');
-**
-** is similar to an UPDATE statement such as: 
-**
-**   UPDATE t1 SET c = rbu_delta(c, 'usa') WHERE a = 4;
-**
-** Finally, if an 'f' character appears in place of a 'd' or 's' in an 
-** ota_control string, the contents of the data_xxx table column is assumed
-** to be a "fossil delta" - a patch to be applied to a blob value in the
-** format used by the fossil source-code management system. In this case
-** the existing value within the target database table must be of type BLOB. 
-** It is replaced by the result of applying the specified fossil delta to
-** itself.
-**
-** If the target database table is a virtual table or a table with no PRIMARY
-** KEY, the rbu_control value should not include a character corresponding 
-** to the rbu_rowid value. For example, this:
-**
-**   INSERT INTO data_ft1(a, b, rbu_rowid, rbu_control) 
-**       VALUES(NULL, 'usa', 12, '.x');
-**
-** causes a result similar to:
-**
-**   UPDATE ft1 SET b = 'usa' WHERE rowid = 12;
-**
-** The data_xxx tables themselves should have no PRIMARY KEY declarations.
-** However, RBU is more efficient if reading the rows in from each data_xxx
-** table in "rowid" order is roughly the same as reading them sorted by
-** the PRIMARY KEY of the corresponding target database table. In other 
-** words, rows should be sorted using the destination table PRIMARY KEY 
-** fields before they are inserted into the data_xxx tables.
-**
-** USAGE
-**
-** The API declared below allows an application to apply an RBU update 
-** stored on disk to an existing target database. Essentially, the 
-** application:
-**
-**     1) Opens an RBU handle using the sqlite3rbu_open() function.
-**
-**     2) Registers any required virtual table modules with the database
-**        handle returned by sqlite3rbu_db(). Also, if required, register
-**        the rbu_delta() implementation.
-**
-**     3) Calls the sqlite3rbu_step() function one or more times on
-**        the new handle. Each call to sqlite3rbu_step() performs a single
-**        b-tree operation, so thousands of calls may be required to apply 
-**        a complete update.
-**
-**     4) Calls sqlite3rbu_close() to close the RBU update handle. If
-**        sqlite3rbu_step() has been called enough times to completely
-**        apply the update to the target database, then the RBU database
-**        is marked as fully applied. Otherwise, the state of the RBU 
-**        update application is saved in the RBU database for later 
-**        resumption.
-**
-** See comments below for more detail on APIs.
-**
-** If an update is only partially applied to the target database by the
-** time sqlite3rbu_close() is called, various state information is saved 
-** within the RBU database. This allows subsequent processes to automatically
-** resume the RBU update from where it left off.
-**
-** To remove all RBU extension state information, returning an RBU database 
-** to its original contents, it is sufficient to drop all tables that begin
-** with the prefix "rbu_"
-**
-** DATABASE LOCKING
-**
-** An RBU update may not be applied to a database in WAL mode. Attempting
-** to do so is an error (SQLITE_ERROR).
-**
-** While an RBU handle is open, a SHARED lock may be held on the target
-** database file. This means it is possible for other clients to read the
-** database, but not to write it.
-**
-** If an RBU update is started and then suspended before it is completed,
-** then an external client writes to the database, then attempting to resume
-** the suspended RBU update is also an error (SQLITE_BUSY).

-This folder contains extensions and utility programs intended to analyze
-live database files, detect problems, and possibly fix them.
-
-As SQLite is being used on larger and larger databases, database sizes
-are growing into the terabyte range.  At that size, hardware malfunctions
-and/or cosmic rays will occasionally corrupt a database file.  Detecting 
-problems and fixing errors a terabyte-sized databases can take hours or days,
-and it is undesirable to take applications that depend on the databases 
-off-line for such a long time.
-The utilities in the folder are intended to provide mechanisms for
-detecting and fixing problems in large databases while those databases
-are in active use.
-
-The utilities and extensions in this folder are experimental and under
-active development at the time of this writing (2017-10-12).  If and when
-they stabilize, this README will be updated to reflect that fact.

-*************************************************************************

-** This module exports a single C function:
-**
-**   int sqlite3_check_freelist(sqlite3 *db, const char *zDb);
-**
-** This function checks the free-list in database zDb (one of "main", 
-** "temp", etc.) and reports any errors by invoking the sqlite3_log()
-** function. It returns SQLITE_OK if successful, or an SQLite error
-** code otherwise. It is not an error if the free-list is corrupted but
-** no IO or OOM errors occur.
-**
-** If this file is compiled and loaded as an SQLite loadable extension,
-** it adds an SQL function "checkfreelist" to the database handle, to
-** be invoked as follows:
-**
-**   SELECT checkfreelist(<database-name>);
-**
-** This function performs the same checks as sqlite3_check_freelist(),
-** except that it returns all error messages as a single text value,
-** separated by newline characters. If the freelist is not corrupted
-** in any way, an empty string is returned.
-**
-** To compile this module for use as an SQLite loadable extension:
-**
-**   gcc -Os -fPIC -shared checkfreelist.c -o checkfreelist.so

-This directory contains an SQLite extension that implements a virtual 
-table type that allows users to create, query and manipulate r-tree[1] 
-data structures inside of SQLite databases. Users create, populate 
-and query r-tree structures using ordinary SQL statements.
-
-    1.  SQL Interface
-
-        1.1  Table Creation
-        1.2  Data Manipulation
-        1.3  Data Querying

-
-
-1. SQL INTERFACE
-
-  1.1 Table Creation.
-
-    All r-tree virtual tables have an odd number of columns between
-    3 and 11. Unlike regular SQLite tables, r-tree tables are strongly 
-    typed. 
-
-    The leftmost column is always the pimary key and contains 64-bit 
-    integer values. Each subsequent column contains a 32-bit real
-    value. For each pair of real values, the first (leftmost) must be 
-    less than or equal to the second. R-tree tables may be 
-    constructed using the following syntax:
-
-      CREATE VIRTUAL TABLE <name> USING rtree(<column-names>)
-
-    For example:
-
-      CREATE VIRTUAL TABLE boxes USING rtree(boxno, xmin, xmax, ymin, ymax);
-      INSERT INTO boxes VALUES(1, 1.0, 3.0, 2.0, 4.0);
-
-    Constructing a virtual r-tree table <name> creates the following three
-    real tables in the database to store the data structure:
-
-      <name>_node
-      <name>_rowid
-      <name>_parent
-
-    Dropping or modifying the contents of these tables directly will
-    corrupt the r-tree structure. To delete an r-tree from a database,
-    use a regular DROP TABLE statement:
-
-      DROP TABLE <name>;
-
-    Dropping the main r-tree table automatically drops the automatically
-    created tables. 
-
-  1.2 Data Manipulation (INSERT, UPDATE, DELETE).
-
-    The usual INSERT, UPDATE or DELETE syntax is used to manipulate data
-    stored in an r-tree table. Please note the following:
-
-      * Inserting a NULL value into the primary key column has the
-        same effect as inserting a NULL into an INTEGER PRIMARY KEY
-        column of a regular table. The system automatically assigns
-        an unused integer key value to the new record. Usually, this
-        is one greater than the largest primary key value currently
-        present in the table.
-
-      * Attempting to insert a duplicate primary key value fails with
-        an SQLITE_CONSTRAINT error.
-
-      * Attempting to insert or modify a record such that the value
-        stored in the (N*2)th column is greater than that stored in
-        the (N*2+1)th column fails with an SQLITE_CONSTRAINT error.
-
-      * When a record is inserted, values are always converted to 
-        the required type (64-bit integer or 32-bit real) as if they
-        were part of an SQL CAST expression. Non-numeric strings are
-        converted to zero.
-
-  1.3 Queries.
-
-    R-tree tables may be queried using all of the same SQL syntax supported
-    by regular tables. However, some query patterns are more efficient
-    than others.
-
-    R-trees support fast lookup by primary key value (O(logN), like 
-    regular tables).
-
-    Any combination of equality and range (<, <=, >, >=) constraints
-    on spatial data columns may be used to optimize other queries. This
-    is the key advantage to using r-tree tables instead of creating 
-    indices on regular tables.
-
-  1.4 Introspection and Analysis.
-
-    TODO: Describe rtreenode() and rtreedepth() functions.
-
-
-2. COMPILATION AND USAGE
-
-  The easiest way to compile and use the RTREE extension is to build
-  and use it as a dynamically loadable SQLite extension. To do this
-  using gcc on *nix:
-
-    gcc -shared rtree.c -o libSqliteRtree.so
-
-  You may need to add "-I" flags so that gcc can find sqlite3ext.h
-  and sqlite3.h. The resulting shared lib, libSqliteRtree.so, may be
-  loaded into sqlite in the same way as any other dynamicly loadable
-  extension.

-** Database Format of R-Tree Tables
-** --------------------------------
-**
-** The data structure for a single virtual r-tree table is stored in three 
-** native SQLite tables declared as follows. In each case, the '%' character
-** in the table name is replaced with the user-supplied name of the r-tree
-** table.
-**
-**   CREATE TABLE %_node(nodeno INTEGER PRIMARY KEY, data BLOB)
-**   CREATE TABLE %_parent(nodeno INTEGER PRIMARY KEY, parentnode INTEGER)
-**   CREATE TABLE %_rowid(rowid INTEGER PRIMARY KEY, nodeno INTEGER, ...)
-**
-** The data for each node of the r-tree structure is stored in the %_node
-** table. For each node that is not the root node of the r-tree, there is
-** an entry in the %_parent table associating the node with its parent.
-** And for each row of data in the table, there is an entry in the %_rowid
-** table that maps from the entries rowid to the id of the node that it
-** is stored on.  If the r-tree contains auxiliary columns, those are stored
-** on the end of the %_rowid table.
-**
-** The root node of an r-tree always exists, even if the r-tree table is
-** empty. The nodeno of the root node is always 1. All other nodes in the
-** table must be the same size as the root node. The content of each node
-** is formatted as follows:
-**
-**   1. If the node is the root node (node 1), then the first 2 bytes
-**      of the node contain the tree depth as a big-endian integer.
-**      For non-root nodes, the first 2 bytes are left unused.
-**
-**   2. The next 2 bytes contain the number of entries currently 
-**      stored in the node.
-**
-**   3. The remainder of the node contains the node entries. Each entry
-**      consists of a single 8-byte integer followed by an even number
-**      of 4-byte coordinates. For leaf nodes the integer is the rowid
-**      of a record. For internal nodes it is the node number of a
-**      child page.

-#              automatic assigning of rowid values.

-#   rtree-4.*: Test INSERT
-#   rtree-5.*: Test DELETE
-#   rtree-6.*: Test UPDATE
-#   rtree-7.*: Test renaming an r-tree table.
-#   rtree-8.*: Test constrained scans of r-tree data.
-#
-#   rtree-12.*: Test that on-conflict clauses are supported.
-#   rtree-13.*: Test that bug [d2889096e7bdeac6d] has been fixed.
-#   rtree-14.*: Test if a non-integer is inserted into the PK column of an
-#               r-tree table, it is converted to an integer before being
-#               inserted. Also that if a non-numeric is inserted into one
-#               of the min/max dimension columns, it is converted to the
-#               required type before being inserted.
-#   rtree-15.*: Check that DROP TABLE works within a transaction that
-#               writes to an r-tree table.

-** RECORD FORMAT:
-**
-** The following record format is similar to (but not compatible with) that 
-** used in SQLite database files. This format is used as part of the 
-** change-set binary format, and so must be architecture independent.
-**
-** Unlike the SQLite database record format, each field is self-contained -
-** there is no separation of header and data. Each field begins with a
-** single byte describing its type, as follows:
-**
-**       0x00: Undefined value.
-**       0x01: Integer value.
-**       0x02: Real value.
-**       0x03: Text value.
-**       0x04: Blob value.
-**       0x05: SQL NULL value.
-**
-** Note that the above match the definitions of SQLITE_INTEGER, SQLITE_TEXT
-** and so on in sqlite3.h. For undefined and NULL values, the field consists
-** only of the single type byte. For other types of values, the type byte
-** is followed by:
-**
-**   Text values:
-**     A varint containing the number of bytes in the value (encoded using
-**     UTF-8). Followed by a buffer containing the UTF-8 representation
-**     of the text value. There is no nul terminator.
-**
-**   Blob values:
-**     A varint containing the number of bytes in the value, followed by
-**     a buffer containing the value itself.
-**
-**   Integer values:
-**     An 8-byte big-endian integer value.
-**
-**   Real values:
-**     An 8-byte big-endian IEEE 754-2008 real value.
-**
-** Varint values are encoded in the same way as varints in the SQLite 
-** record format.
-**
-** CHANGESET FORMAT:
-**
-** A changeset is a collection of DELETE, UPDATE and INSERT operations on
-** one or more tables. Operations on a single table are grouped together,
-** but may occur in any order (i.e. deletes, updates and inserts are all
-** mixed together).
-**
-** Each group of changes begins with a table header:
-**
-**   1 byte: Constant 0x54 (capital 'T')
-**   Varint: Number of columns in the table.
-**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
-**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
-**
-** Followed by one or more changes to the table.
-**
-**   1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09).
-**   1 byte: The "indirect-change" flag.
-**   old.* record: (delete and update only)
-**   new.* record: (insert and update only)
-**
-** The "old.*" and "new.*" records, if present, are N field records in the
-** format described above under "RECORD FORMAT", where N is the number of
-** columns in the table. The i'th field of each record is associated with
-** the i'th column of the table, counting from left to right in the order
-** in which columns were declared in the CREATE TABLE statement.
-**
-** The new.* record that is part of each INSERT change contains the values
-** that make up the new row. Similarly, the old.* record that is part of each
-** DELETE change contains the values that made up the row that was deleted 
-** from the database. In the changeset format, the records that are part
-** of INSERT or DELETE changes never contain any undefined (type byte 0x00)
-** fields.
-**
-** Within the old.* record associated with an UPDATE change, all fields
-** associated with table columns that are not PRIMARY KEY columns and are
-** not modified by the UPDATE change are set to "undefined". Other fields
-** are set to the values that made up the row before the UPDATE that the
-** change records took place. Within the new.* record, fields associated 
-** with table columns modified by the UPDATE change contain the new 
-** values. Fields associated with table columns that are not modified
-** are set to "undefined".
-**
-** PATCHSET FORMAT:
-**
-** A patchset is also a collection of changes. It is similar to a changeset,
-** but leaves undefined those fields that are not useful if no conflict
-** resolution is required when applying the changeset.
-**
-** Each group of changes begins with a table header:
-**
-**   1 byte: Constant 0x50 (capital 'P')
-**   Varint: Number of columns in the table.
-**   nCol bytes: 0x01 for PK columns, 0x00 otherwise.
-**   N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated.
-**
-** Followed by one or more changes to the table.
-**
-**   1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09).
-**   1 byte: The "indirect-change" flag.
-**   single record: (PK fields for DELETE, PK and modified fields for UPDATE,
-**                   full record for INSERT).
-**
-** As in the changeset format, each field of the single record that is part
-** of a patchset change is associated with the correspondingly positioned
-** table column, counting from left to right within the CREATE TABLE 
-** statement.
-**
-** For a DELETE change, all fields within the record except those associated
-** with PRIMARY KEY columns are omitted. The PRIMARY KEY fields contain the
-** values identifying the row to delete.
-**
-** For an UPDATE change, all fields except those associated with PRIMARY KEY
-** columns and columns that are modified by the UPDATE are set to "undefined".
-** PRIMARY KEY fields contain the values identifying the table row to update,
-** and fields associated with modified columns contain the new column values.
-**
-** The records associated with INSERT changes are in the same format as for
-** changesets. It is not possible for a record associated with an INSERT
-** change to contain a field set to "undefined".

-** <h3>Special sqlite_stat1 Handling</h3>
-**
-** As of SQLite version 3.22.0, the "sqlite_stat1" table is an exception to 
-** some of the rules above. In SQLite, the schema of sqlite_stat1 is:
-**  <pre>
-**  &nbsp;     CREATE TABLE sqlite_stat1(tbl,idx,stat)  
-**  </pre>
-**
-** Even though sqlite_stat1 does not have a PRIMARY KEY, changes are 
-** recorded for it as if the PRIMARY KEY is (tbl,idx). Additionally, changes 
-** are recorded for rows for which (idx IS NULL) is true. However, for such
-** rows a zero-length blob (SQL value X'') is stored in the changeset or
-** patchset instead of a NULL value. This allows such changesets to be
-** manipulated by legacy implementations of sqlite3changeset_invert(),
-** concat() and similar.
-**
-** The sqlite3changeset_apply() function automatically converts the 
-** zero-length blob back to a NULL value when updating the sqlite_stat1
-** table. However, if the application calls sqlite3changeset_new(),
-** sqlite3changeset_old() or sqlite3changeset_conflict on a changeset 
-** iterator directly (including on a changeset iterator passed to a
-** conflict-handler callback) then the X'' value is returned. The application
-** must translate X'' to NULL itself if required.
-**
-** Legacy (older than 3.22.0) versions of the sessions module cannot capture
-** changes made to the sqlite_stat1 table. Legacy versions of the
-** sqlite3changeset_apply() function silently ignore any modifications to the
-** sqlite_stat1 table that are part of a changeset or patchset.

-** CAPI3REF: Generate A Changeset From A Session Object
-** METHOD: sqlite3_session
-**
-** Obtain a changeset containing changes to the tables attached to the

-** set *ppChangeset to point to a buffer containing the changeset 
-** and *pnChangeset to the size of the changeset in bytes before returning
-** SQLITE_OK. If an error occurs, set both *ppChangeset and *pnChangeset to
-** zero and return an SQLite error code.
-**
-** A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes,
-** each representing a change to a single row of an attached table. An INSERT
-** change contains the values of each field of a new database row. A DELETE
-** contains the original values of each field of a deleted database row. An
-** UPDATE change contains the original values of each field of an updated
-** database row along with the updated values for each updated non-primary-key
-** column. It is not possible for an UPDATE change to represent a change that
-** modifies the values of primary key columns. If such a change is made, it
-** is represented in a changeset as a DELETE followed by an INSERT.
-**
-** Changes are not recorded for rows that have NULL values stored in one or 
-** more of their PRIMARY KEY columns. If such a row is inserted or deleted,
-** no corresponding change is present in the changesets returned by this
-** function. If an existing row with one or more NULL values stored in
-** PRIMARY KEY columns is updated so that all PRIMARY KEY columns are non-NULL,
-** only an INSERT is appears in the changeset. Similarly, if an existing row
-** with non-NULL PRIMARY KEY values is updated so that one or more of its
-** PRIMARY KEY columns are set to NULL, the resulting changeset contains a
-** DELETE change only.
-**
-** The contents of a changeset may be traversed using an iterator created
-** using the [sqlite3changeset_start()] API. A changeset may be applied to
-** a database with a compatible schema using the [sqlite3changeset_apply()]
-** API.
-**
-** Within a changeset generated by this function, all changes related to a
-** single table are grouped together. In other words, when iterating through
-** a changeset or when applying a changeset to a database, all changes related
-** to a single table are processed before moving on to the next table. Tables
-** are sorted in the same order in which they were attached (or auto-attached)
-** to the sqlite3_session object. The order in which the changes related to
-** a single table are stored is undefined.
-**
-** Following a successful call to this function, it is the responsibility of
-** the caller to eventually free the buffer that *ppChangeset points to using
-** [sqlite3_free()].
-**
-** <h3>Changeset Generation</h3>
-**
-** Once a table has been attached to a session object, the session object
-** records the primary key values of all new rows inserted into the table.
-** It also records the original primary key and other column values of any
-** deleted or updated rows. For each unique primary key value, data is only
-** recorded once - the first time a row with said primary key is inserted,
-** updated or deleted in the lifetime of the session.
-**
-** There is one exception to the previous paragraph: when a row is inserted,
-** updated or deleted, if one or more of its primary key columns contain a
-** NULL value, no record of the change is made.
-**
-** The session object therefore accumulates two types of records - those
-** that consist of primary key values only (created when the user inserts
-** a new record) and those that consist of the primary key values and the
-** original values of other table columns (created when the users deletes
-** or updates a record).
-**
-** When this function is called, the requested changeset is created using
-** both the accumulated records and the current contents of the database
-** file. Specifically:
-**
-** <ul>
-**   <li> For each record generated by an insert, the database is queried
-**        for a row with a matching primary key. If one is found, an INSERT
-**        change is added to the changeset. If no such row is found, no change 
-**        is added to the changeset.
-**
-**   <li> For each record generated by an update or delete, the database is 
-**        queried for a row with a matching primary key. If such a row is
-**        found and one or more of the non-primary key fields have been
-**        modified from their original values, an UPDATE change is added to 
-**        the changeset. Or, if no such row is found in the table, a DELETE 
-**        change is added to the changeset. If there is a row with a matching
-**        primary key in the database, but all fields contain their original
-**        values, no change is added to the changeset.
-** </ul>
-**
-** This means, amongst other things, that if a row is inserted and then later
-** deleted while a session object is active, neither the insert nor the delete
-** will be present in the changeset. Or if a row is deleted and then later a 
-** row with the same primary key values inserted while a session object is
-** active, the resulting changeset will contain an UPDATE change instead of
-** a DELETE and an INSERT.
-**
-** When a session object is disabled (see the [sqlite3session_enable()] API),
-** it does not accumulate records when rows are inserted, updated or deleted.
-** This may appear to have some counter-intuitive effects if a single row
-** is written to more than once during a session. For example, if a row
-** is inserted while a session object is enabled, then later deleted while 
-** the same session object is disabled, no INSERT record will appear in the
-** changeset, even though the delete took place while the session was disabled.

-** If it is not already attached to the session object passed as the first

-** [sqlite3session_attach()] function. If zTbl does not exist, or if it
-** does not have a primary key, this function is a no-op (but does not return
-** an error).
-**
-** Argument zFromDb must be the name of a database ("main", "temp" etc.)
-** attached to the same database handle as the session object that contains 
-** a table compatible with the table attached to the session by this function.
-** A table is considered compatible if it:
-**
-** <ul>
-**   <li> Has the same name,
-**   <li> Has the same set of columns declared in the same order, and
-**   <li> Has the same PRIMARY KEY definition.
-** </ul>
-**
-** If the tables are not compatible, SQLITE_SCHEMA is returned. If the tables
-** are compatible but do not have any PRIMARY KEY columns, it is not an error
-** but no changes are added to the session object. As with other session
-** APIs, tables without PRIMARY KEYs are simply ignored.
-**
-** This function adds a set of changes to the session object that could be
-** used to update the table in database zFrom (call this the "from-table") 
-** so that its content is the same as the table attached to the session 
-** object (call this the "to-table"). Specifically:
-**
-** <ul>
-**   <li> For each row (primary key) that exists in the to-table but not in 
-**     the from-table, an INSERT record is added to the session object.
-**
-**   <li> For each row (primary key) that exists in the to-table but not in 
-**     the from-table, a DELETE record is added to the session object.
-**
-**   <li> For each row (primary key) that exists in both tables, but features 
-**     different non-PK values in each, an UPDATE record is added to the
-**     session.  
-** </ul>
-**
-** To clarify, if this function is called and then a changeset constructed
-** using [sqlite3session_changeset()], then after applying that changeset to 
-** database zFrom the contents of the two compatible tables would be 
-** identical.
-**
-** It an error if database zFrom does not exist or does not contain the
-** required compatible table.
-**
-** If the operation successful, SQLITE_OK is returned. Otherwise, an SQLite
-** error code. In this case, if argument pzErrMsg is not NULL, *pzErrMsg

-** CAPI3REF: Apply A Changeset To A Database
-**
-** Apply a changeset or patchset to a database. These functions attempt to
-** update the "main" database attached to handle db with the changes found in
-** the changeset passed via the second and third arguments. 
-**
-** The fourth argument (xFilter) passed to these functions is the "filter
-** callback". If it is not NULL, then for each table affected by at least one
-** change in the changeset, the filter callback is invoked with
-** the table name as the second argument, and a copy of the context pointer
-** passed as the sixth argument as the first. If the "filter callback"
-** returns zero, then no attempt is made to apply any changes to the table.
-** Otherwise, if the return value is non-zero or the xFilter argument to
-** is NULL, all changes related to the table are attempted.
-**
-** For each table that is not excluded by the filter callback, this function 
-** tests that the target database contains a compatible table. A table is 
-** considered compatible if all of the following are true:
-**
-** <ul>
-**   <li> The table has the same name as the name recorded in the 
-**        changeset, and
-**   <li> The table has at least as many columns as recorded in the 
-**        changeset, and
-**   <li> The table has primary key columns in the same position as 
-**        recorded in the changeset.
-** </ul>
-**
-** If there is no compatible table, it is not an error, but none of the
-** changes associated with the table are applied. A warning message is issued
-** via the sqlite3_log() mechanism with the error code SQLITE_SCHEMA. At most
-** one such warning is issued for each table in the changeset.
-**
-** For each change for which there is a compatible table, an attempt is made 
-** to modify the table contents according to the UPDATE, INSERT or DELETE 
-** change. If a change cannot be applied cleanly, the conflict handler 
-** function passed as the fifth argument to sqlite3changeset_apply() may be 
-** invoked. A description of exactly when the conflict handler is invoked for 
-** each type of change is below.
-**
-** Unlike the xFilter argument, xConflict may not be passed NULL. The results
-** of passing anything other than a valid function pointer as the xConflict
-** argument are undefined.
-**
-** Each time the conflict handler function is invoked, it must return one
-** of [SQLITE_CHANGESET_OMIT], [SQLITE_CHANGESET_ABORT] or 
-** [SQLITE_CHANGESET_REPLACE]. SQLITE_CHANGESET_REPLACE may only be returned
-** if the second argument passed to the conflict handler is either
-** SQLITE_CHANGESET_DATA or SQLITE_CHANGESET_CONFLICT. If the conflict-handler
-** returns an illegal value, any changes already made are rolled back and
-** the call to sqlite3changeset_apply() returns SQLITE_MISUSE. Different 
-** actions are taken by sqlite3changeset_apply() depending on the value
-** returned by each invocation of the conflict-handler function. Refer to
-** the documentation for the three 
-** [SQLITE_CHANGESET_OMIT|available return values] for details.
-**
-** <dl>
-** <dt>DELETE Changes<dd>
-**   For each DELETE change, the function checks if the target database 
-**   contains a row with the same primary key value (or values) as the 
-**   original row values stored in the changeset. If it does, and the values 
-**   stored in all non-primary key columns also match the values stored in 
-**   the changeset the row is deleted from the target database.
-**
-**   If a row with matching primary key values is found, but one or more of
-**   the non-primary key fields contains a value different from the original
-**   row value stored in the changeset, the conflict-handler function is
-**   invoked with [SQLITE_CHANGESET_DATA] as the second argument. If the
-**   database table has more columns than are recorded in the changeset,
-**   only the values of those non-primary key fields are compared against
-**   the current database contents - any trailing database table columns
-**   are ignored.
-**
-**   If no row with matching primary key values is found in the database,
-**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
-**   passed as the second argument.
-**
-**   If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT
-**   (which can only happen if a foreign key constraint is violated), the
-**   conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT]
-**   passed as the second argument. This includes the case where the DELETE
-**   operation is attempted because an earlier call to the conflict handler
-**   function returned [SQLITE_CHANGESET_REPLACE].
-**
-** <dt>INSERT Changes<dd>
-**   For each INSERT change, an attempt is made to insert the new row into
-**   the database. If the changeset row contains fewer fields than the
-**   database table, the trailing fields are populated with their default
-**   values.
-**
-**   If the attempt to insert the row fails because the database already 
-**   contains a row with the same primary key values, the conflict handler
-**   function is invoked with the second argument set to 
-**   [SQLITE_CHANGESET_CONFLICT].
-**
-**   If the attempt to insert the row fails because of some other constraint
-**   violation (e.g. NOT NULL or UNIQUE), the conflict handler function is 
-**   invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT].
-**   This includes the case where the INSERT operation is re-attempted because 
-**   an earlier call to the conflict handler function returned 
-**   [SQLITE_CHANGESET_REPLACE].
-**
-** <dt>UPDATE Changes<dd>
-**   For each UPDATE change, the function checks if the target database 
-**   contains a row with the same primary key value (or values) as the 
-**   original row values stored in the changeset. If it does, and the values 
-**   stored in all modified non-primary key columns also match the values
-**   stored in the changeset the row is updated within the target database.
-**
-**   If a row with matching primary key values is found, but one or more of
-**   the modified non-primary key fields contains a value different from an
-**   original row value stored in the changeset, the conflict-handler function
-**   is invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since
-**   UPDATE changes only contain values for non-primary key fields that are
-**   to be modified, only those fields need to match the original values to
-**   avoid the SQLITE_CHANGESET_DATA conflict-handler callback.
-**
-**   If no row with matching primary key values is found in the database,
-**   the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND]
-**   passed as the second argument.
-**
-**   If the UPDATE operation is attempted, but SQLite returns 
-**   SQLITE_CONSTRAINT, the conflict-handler function is invoked with 
-**   [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument.
-**   This includes the case where the UPDATE operation is attempted after 
-**   an earlier call to the conflict handler function returned
-**   [SQLITE_CHANGESET_REPLACE].  
-** </dl>
-**
-** It is safe to execute SQL statements, including those that write to the
-** table that the callback related to, from within the xConflict callback.
-** This can be used to further customize the applications conflict
-** resolution strategy.
-**
-** All changes made by these functions are enclosed in a savepoint transaction.
-** If any other error (aside from a constraint failure when attempting to
-** write to the target database) occurs, then the savepoint transaction is
-** rolled back, restoring the target database to its original state, and an 
-** SQLite error code returned.
-**
-** If the output parameters (ppRebase) and (pnRebase) are non-NULL and
-** the input is a changeset (not a patchset), then sqlite3changeset_apply_v2()
-** may set (*ppRebase) to point to a "rebase" that may be used with the

-** CAPI3REF: Rebasing changesets
-** EXPERIMENTAL
-**
-** Suppose there is a site hosting a database in state S0. And that
-** modifications are made that move that database to state S1 and a
-** changeset recorded (the "local" changeset). Then, a changeset based
-** on S0 is received from another site (the "remote" changeset) and 
-** applied to the database. The database is then in state 
-** (S1+"remote"), where the exact state depends on any conflict
-** resolution decisions (OMIT or REPLACE) made while applying "remote".
-** Rebasing a changeset is to update it to take those conflict 
-** resolution decisions into account, so that the same conflicts
-** do not have to be resolved elsewhere in the network. 
-**
-** For example, if both the local and remote changesets contain an
-** INSERT of the same key on "CREATE TABLE t1(a PRIMARY KEY, b)":
-**
-**   local:  INSERT INTO t1 VALUES(1, 'v1');
-**   remote: INSERT INTO t1 VALUES(1, 'v2');
-**
-** and the conflict resolution is REPLACE, then the INSERT change is
-** removed from the local changeset (it was overridden). Or, if the
-** conflict resolution was "OMIT", then the local changeset is modified
-** to instead contain:
-**
-**           UPDATE t1 SET b = 'v2' WHERE a=1;
-**
-** Changes within the local changeset are rebased as follows:
-**
-** <dl>
-** <dt>Local INSERT<dd>
-**   This may only conflict with a remote INSERT. If the conflict 
-**   resolution was OMIT, then add an UPDATE change to the rebased
-**   changeset. Or, if the conflict resolution was REPLACE, add
-**   nothing to the rebased changeset.
-**
-** <dt>Local DELETE<dd>
-**   This may conflict with a remote UPDATE or DELETE. In both cases the
-**   only possible resolution is OMIT. If the remote operation was a
-**   DELETE, then add no change to the rebased changeset. If the remote
-**   operation was an UPDATE, then the old.* fields of change are updated
-**   to reflect the new.* values in the UPDATE.
-**
-** <dt>Local UPDATE<dd>
-**   This may conflict with a remote UPDATE or DELETE. If it conflicts
-**   with a DELETE, and the conflict resolution was OMIT, then the update
-**   is changed into an INSERT. Any undefined values in the new.* record
-**   from the update change are filled in using the old.* values from
-**   the conflicting DELETE. Or, if the conflict resolution was REPLACE,
-**   the UPDATE change is simply omitted from the rebased changeset.
-**
-**   If conflict is with a remote UPDATE and the resolution is OMIT, then
-**   the old.* values are rebased using the new.* values in the remote
-**   change. Or, if the resolution is REPLACE, then the change is copied
-**   into the rebased changeset with updates to columns also updated by
-**   the conflicting remote UPDATE removed. If this means no columns would 
-**   be updated, the change is omitted.
-** </dl>
-**
-** A local change may be rebased against multiple remote changes 
-** simultaneously. If a single key is modified by multiple remote 
-** changesets, they are combined as follows before the local changeset
-** is rebased:
-**
-** <ul>
-**    <li> If there has been one or more REPLACE resolutions on a
-**         key, it is rebased according to a REPLACE.
-**
-**    <li> If there have been no REPLACE resolutions on a key, then
-**         the local changeset is rebased according to the most recent
-**         of the OMIT resolutions.
-** </ul>
-**
-** Note that conflict resolutions from multiple remote changesets are 
-** combined on a per-field basis, not per-row. This means that in the 
-** case of multiple remote UPDATE operations, some fields of a single 
-** local change may be rebased for REPLACE while others are rebased for 
-** OMIT.
-**
-** In order to rebase a local changeset, the remote changeset must first
-** be applied to the local database using sqlite3changeset_apply_v2() and
-** the buffer of rebase information captured. Then:
-**
-** <ol>
-**   <li> An sqlite3_rebaser object is created by calling 
-**        sqlite3rebaser_create().
-**   <li> The new object is configured with the rebase buffer obtained from
-**        sqlite3changeset_apply_v2() by calling sqlite3rebaser_configure().
-**        If the local changeset is to be rebased against multiple remote
-**        changesets, then sqlite3rebaser_configure() should be called
-**        multiple times, in the same order that the multiple
-**        sqlite3changeset_apply_v2() calls were made.
-**   <li> Each local changeset is rebased by calling sqlite3rebaser_rebase().

-** CAPI3REF: Streaming Versions of API functions.
-**
-** The six streaming API xxx_strm() functions serve similar purposes to the 
-** corresponding non-streaming API functions:
-**
-** <table border=1 style="margin-left:8ex;margin-right:8ex">
-**   <tr><th>Streaming function<th>Non-streaming equivalent</th>
-**   <tr><td>sqlite3changeset_apply_strm<td>[sqlite3changeset_apply] 
-**   <tr><td>sqlite3changeset_apply_strm_v2<td>[sqlite3changeset_apply_v2] 
-**   <tr><td>sqlite3changeset_concat_strm<td>[sqlite3changeset_concat]

-**   <tr><td>sqlite3session_changeset_strm<td>[sqlite3session_changeset] 
-**   <tr><td>sqlite3session_patchset_strm<td>[sqlite3session_patchset] 
-** </table>
-**
-** Non-streaming functions that accept changesets (or patchsets) as input
-** require that the entire changeset be stored in a single buffer in memory. 
-** Similarly, those that return a changeset or patchset do so by returning 
-** a pointer to a single large buffer allocated using sqlite3_malloc(). 
-** Normally this is convenient. However, if an application running in a 
-** low-memory environment is required to handle very large changesets, the
-** large contiguous memory allocations required can become onerous.
-**
-** In order to avoid this problem, instead of a single large buffer, input
-** is passed to a streaming API functions by way of a callback function that
-** the sessions module invokes to incrementally request input data as it is
-** required. In all cases, a pair of API function parameters such as
-**
-**  <pre>
-**  &nbsp;     int nChangeset,
-**  &nbsp;     void *pChangeset,
-**  </pre>
-**
-** Is replaced by:
-**
-**  <pre>
-**  &nbsp;     int (*xInput)(void *pIn, void *pData, int *pnData),
-**  &nbsp;     void *pIn,
-**  </pre>
-**
-** Each time the xInput callback is invoked by the sessions module, the first
-** argument passed is a copy of the supplied pIn context pointer. The second 
-** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no 
-** error occurs the xInput method should copy up to (*pnData) bytes of data 
-** into the buffer and set (*pnData) to the actual number of bytes copied 
-** before returning SQLITE_OK. If the input is completely exhausted, (*pnData) 
-** should be set to zero to indicate this. Or, if an error occurs, an SQLite 
-** error code should be returned. In all cases, if an xInput callback returns
-** an error, all processing is abandoned and the streaming API function
-** returns a copy of the error code to the caller.
-**
-** In the case of sqlite3changeset_start_strm(), the xInput callback may be
-** invoked by the sessions module at any point during the lifetime of the
-** iterator. If such an xInput callback returns an error, the iterator enters
-** an error state, whereby all subsequent calls to iterator functions 
-** immediately fail with the same error code as returned by xInput.
-**
-** Similarly, streaming API functions that return changesets (or patchsets)
-** return them in chunks by way of a callback function instead of via a
-** pointer to a single large buffer. In this case, a pair of parameters such
-** as:
-**
-**  <pre>
-**  &nbsp;     int *pnChangeset,
-**  &nbsp;     void **ppChangeset,
-**  </pre>
-**
-** Is replaced by:
-**
-**  <pre>
-**  &nbsp;     int (*xOutput)(void *pOut, const void *pData, int nData),
-**  &nbsp;     void *pOut
-**  </pre>
-**
-** The xOutput callback is invoked zero or more times to return data to
-** the application. The first parameter passed to each call is a copy of the
-** pOut pointer supplied by the application. The second parameter, pData,
-** points to a buffer nData bytes in size containing the chunk of output
-** data being returned. If the xOutput callback successfully processes the
-** supplied data, it should return SQLITE_OK to indicate success. Otherwise,
-** it should return some other SQLite error code. In this case processing
-** is immediately abandoned and the streaming API function returns a copy
-** of the xOutput error code to the application.
-**
-** The sessions module never invokes an xOutput callback with the third 
-** parameter set to a value less than or equal to zero. Other than this,
-** no guarantees are made as to the size of the chunks of data returned.

-Activate the user authentication logic by including the

-adding the -DSQLITE_USER_AUTHENTICATION compile-time option.
-The ext/userauth/sqlite3userauth.h header file is available to
-applications to define the interface.
-
-When using the SQLite amalgamation, it is sufficient to append
-the ext/userauth/userauth.c source file onto the end of the

-     const char *zUsername, /* Username */
-     const char *aPW,       /* Password or credentials */

-   );
-
-With this extension, a database can be marked as requiring authentication.
-By default a database does not require authentication.
-
-The sqlite3_open(), sqlite3_open16(), and sqlite3_open_v2() interfaces
-work as before: they open a new database connection.  However, if the
-database being opened requires authentication, then attempts to read
-or write from the database will fail with an SQLITE_AUTH error until 
-after sqlite3_user_authenticate() has been called successfully.  The 
-sqlite3_user_authenticate() call will return SQLITE_OK if the 
-authentication credentials are accepted and SQLITE_ERROR if not.
-
-Calling sqlite3_user_authenticate() on a no-authentication-required
-database connection is a harmless no-op.  
-
-If the database is encrypted, then sqlite3_key_v2() must be called first,
-with the correct decryption key, prior to invoking sqlite3_user_authenticate().
-
-To recapitulate: When opening an existing unencrypted authentication-
-required database, the call sequence is:
-
-    sqlite3_open_v2()
-    sqlite3_user_authenticate();
-    /* Database is now usable */
-
-To open an existing, encrypted, authentication-required database, the
-call sequence is:
-
-    sqlite3_open_v2();
-    sqlite3_key_v2();
-    sqlite3_user_authenticate();
-    /* Database is now usable */
-
-When opening a no-authentication-required database, the database
-connection is treated as if it was authenticated as an admin user.
-
-When ATTACH-ing new database files to a connection, each newly attached
-database that is an authentication-required database is checked using
-the same username and password as supplied to the main database.  If that
-check fails, then the ATTACH command fails with an SQLITE_AUTH error.
-
-The sqlite3_user_add() interface can be used (by an admin user only)
-to create a new user.  When called on a no-authentication-required
-database and when A is true, the sqlite3_user_add(D,U,P,N,A) routine
-converts the database into an authentication-required database and
-logs in the database connection D as user U with password P,N.
-To convert a no-authentication-required database into an authentication-
-required database, the isAdmin parameter must be true.  If
-sqlite3_user_add(D,U,P,N,A) is called on a no-authentication-required
-database and A is false, then the call fails with an SQLITE_AUTH error.
-
-Any call to sqlite3_user_add() by a non-admin user results in an error.
-
-Hence, to create a new, unencrypted, authentication-required database,
-the call sequence is:
-
-    sqlite3_open_v2();
-    sqlite3_user_add();
-
-And to create a new, encrypted, authentication-required database, the call
-sequence is:
-
-    sqlite3_open_v2();
-    sqlite3_key_v2();
-    sqlite3_user_add();
-
-The sqlite3_user_delete() interface can be used (by an admin user only)
-to delete a user.  The currently logged-in user cannot be deleted,
-which guarantees that there is always an admin user and hence that
-the database cannot be converted into a no-authentication-required
-database.
-
-The sqlite3_user_change() interface can be used to change a users
-login credentials or admin privilege.  Any user can change their own
-password.  Only an admin user can change another users login
-credentials or admin privilege setting.  No user may change their own 
-admin privilege setting.
-
-The sqlite3_set_authorizer() callback is modified to take a 7th parameter
-which is the username of the currently logged in user, or NULL for a
-no-authentication-required database.
-
------------------------------------------------------------------------------
-Implementation notes:
-
-An authentication-required database is identified by the presence of a
-new table:
-
-    CREATE TABLE sqlite_user(
-      uname TEXT PRIMARY KEY,
-      isAdmin BOOLEAN,
-      pw BLOB
-    ) WITHOUT ROWID;
-
-The sqlite_user table is inaccessible (unreadable and unwriteable) to
-non-admin users and is read-only for admin users.  However, if the same
-database file is opened by a version of SQLite that omits
-the -DSQLITE_USER_AUTHENTICATION compile-time option, then the sqlite_user
-table will be readable by anybody and writeable by anybody if
-the "PRAGMA writable_schema=ON" statement is run first.
-
-The sqlite_user.pw field is encoded by a built-in SQL function
-"sqlite_crypt(X,Y)".  The two arguments are both BLOBs.  The first argument
-is the plaintext password supplied to the sqlite3_user_authenticate()
-interface.  The second argument is the sqlite_user.pw value and is supplied
-so that the function can extract the "salt" used by the password encoder.
-The result of sqlite_crypt(X,Y) is another blob which is the value that
-ends up being stored in sqlite_user.pw.  To verify credentials X supplied
-by the sqlite3_user_authenticate() routine, SQLite runs:
-
-    sqlite_user.pw == sqlite_crypt(X, sqlite_user.pw)
-
-To compute an appropriate sqlite_user.pw value from a new or modified
-password X, sqlite_crypt(X,NULL) is run.  A new random salt is selected
-when the second argument is NULL.
-
-The built-in version of of sqlite_crypt() uses a simple Ceasar-cypher
-which prevents passwords from being revealed by searching the raw database
-for ASCII text, but is otherwise trivally broken.  For better password
-security, the database should be encrypted using the SQLite Encryption
-Extension or similar technology.  Or, the application can use the
-sqlite3_create_function() interface to provide an alternative
-implementation of sqlite_crypt() that computes a stronger password hash,
-perhaps using a cryptographic hash function like SHA1.

-# support having both static and shared libraries enabled at the same

-# This file contains suggested magic(5) text for the unix file(1)
-# utility for recognizing SQLite3 databases.
-#
-# When SQLite is used as an application file format, it is desirable to
-# have file(1) recognize the database file as being with the specific
-# application.  You can set the application_id for a database file
-# using:
-#
-#     PRAGMA application_id = INTEGER;
-#
-# INTEGER can be any signed 32-bit integer.  That integer is written as
-# a 4-byte big-endian integer into offset 68 of the database header. 
-#
-# The Monotone application used "PRAGMA user_version=1598903374;" to set
-# its identifier long before "PRAGMA application_id" became available.
-# The user_version is very similar to application_id except that it is
-# stored at offset 68 instead of offset 60.  The application_id pragma
-# is preferred.  The rule using offset 60 for Monotone is for historical
-# compatibility only.

-# The following macros should be defined before this script is
-# invoked:
-#
-# TOP              The toplevel directory of the source tree.  This is the
-#                  directory that contains this "Makefile.in" and the
-#                  "configure.in" script.
-#
-# BCC              C Compiler and options for use in building executables that
-#                  will run on the platform that is doing the build.
-#
-# THREADLIB        Specify any extra linker options needed to make the library
-#                  thread safe
-#
-# LIBS             Extra libraries options
-#
-# OPTS             Extra compiler command-line options.
-#
-# EXE              The suffix to add to executable files.  ".exe" for windows
-#                  and "" for Unix.
-#
-# TCC              C Compiler and options for use in building executables that 
-#                  will run on the target platform.  This is usually the same
-#                  as BCC, unless you are cross-compiling.
-#
-# AR               Tools used to build a static library.
-# RANLIB
-#
-# TCL_FLAGS        Extra compiler options needed for programs that use the
-#                  TCL library.
-#
-# LIBTCL           Linker options needed to link against the TCL library.
-#
-# READLINE_FLAGS   Compiler options needed for programs that use the
-#                  readline() library.
-#
-# LIBREADLINE      Linker options needed by programs using readline() must
-#                  link against.

-# Once the macros above are defined, the rest of this make script will

-SQLite is a software library that implements a self-contained, serverless,
-zero-configuration, transactional SQL database engine.
-Programs that link with the SQLite library can have SQL database access
-without running a separate RDBMS process. The distribution comes with a
-standalone command-line access program (sqlite) that can be used to
-administer an SQLite database and which serves as an example of how to
-use the SQLite library.

-.SH NAME
-.B sqlite3 
-\- A command line interface for SQLite version 3
-
-.SH SYNOPSIS
-.B sqlite3
-.RI [ options ]
-.RI [ databasefile ]
-.RI [ SQL ]
-
-.SH SUMMARY
-.PP
-.B sqlite3
-is a terminal-based front-end to the SQLite library that can evaluate
-queries interactively and display the results in multiple formats.
-.B sqlite3
-can also be used within shell scripts and other applications to provide
-batch processing features.
-
-.SH DESCRIPTION
-To start a
-.B sqlite3
-interactive session, invoke the
-.B sqlite3
-command and optionally provide the name of a database file.  If the
-database file does not exist, it will be created.  If the database file
-does exist, it will be opened.
-
-For example, to create a new database file named "mydata.db", create
-a table named "memos" and insert a couple of records into that table:
-.sp
-$ 
-.B sqlite3 mydata.db
-.br
-SQLite version 3.8.8
-.br
-Enter ".help" for instructions
-.br
-sqlite>
-.B create table memos(text, priority INTEGER);
-.br
-sqlite>
-.B insert into memos values('deliver project description', 10);
-.br
-sqlite>
-.B insert into memos values('lunch with Christine', 100);
-.br
-sqlite>
-.B select * from memos;
-.br
-deliver project description|10
-.br
-lunch with Christine|100
-.br
-sqlite>
-.sp
-
-If no database name is supplied, the ATTACH sql command can be used
-to attach to existing or create new database files.  ATTACH can also
-be used to attach to multiple databases within the same interactive
-session.  This is useful for migrating data between databases,
-possibly changing the schema along the way.
-
-Optionally, a SQL statement or set of SQL statements can be supplied as
-a single argument.  Multiple statements should be separated by
-semi-colons.
-
-For example:
-.sp
-$ 
-.B sqlite3 -line mydata.db 'select * from memos where priority > 20;'
-.br
-    text = lunch with Christine
-.br
-priority = 100
-.br
-.sp
-
-.SS SQLITE META-COMMANDS
-.PP
-The interactive interpreter offers a set of meta-commands that can be
-used to control the output format, examine the currently attached
-database files, or perform administrative operations upon the
-attached databases (such as rebuilding indices).   Meta-commands are
-always prefixed with a dot (.).
-
-A list of available meta-commands can be viewed at any time by issuing
-the '.help' command.  For example:
-.sp
-sqlite>
-.B .help
-.nf
-.tr %.

-*************************************************************************
-** This file contains code associated with the ANALYZE command.
-**
-** The ANALYZE command gather statistics about the content of tables
-** and indices.  These statistics are made available to the query planner
-** to help it make better decisions about how to perform queries.
-**
-** The following system tables are or have been supported:
-**
-**    CREATE TABLE sqlite_stat1(tbl, idx, stat);
-**    CREATE TABLE sqlite_stat2(tbl, idx, sampleno, sample);
-**    CREATE TABLE sqlite_stat3(tbl, idx, nEq, nLt, nDLt, sample);
-**    CREATE TABLE sqlite_stat4(tbl, idx, nEq, nLt, nDLt, sample);
-**
-** Additional tables might be added in future releases of SQLite.
-** The sqlite_stat2 table is not created or used unless the SQLite version
-** is between 3.6.18 and 3.7.8, inclusive, and unless SQLite is compiled
-** with SQLITE_ENABLE_STAT2.  The sqlite_stat2 table is deprecated.
-** The sqlite_stat2 table is superseded by sqlite_stat3, which is only
-** created and used by SQLite versions 3.7.9 and later and with
-** SQLITE_ENABLE_STAT3 defined.  The functionality of sqlite_stat3
-** is a superset of sqlite_stat2.  The sqlite_stat4 is an enhanced
-** version of sqlite_stat3 and is only available when compiled with
-** SQLITE_ENABLE_STAT4 and in SQLite versions 3.8.1 and later.  It is
-** not possible to enable both STAT3 and STAT4 at the same time.  If they
-** are both enabled, then STAT4 takes precedence.
-**
-** For most applications, sqlite_stat1 provides all the statistics required
-** for the query planner to make good choices.
-**
-** Format of sqlite_stat1:
-**
-** There is normally one row per index, with the index identified by the
-** name in the idx column.  The tbl column is the name of the table to
-** which the index belongs.  In each such row, the stat column will be
-** a string consisting of a list of integers.  The first integer in this
-** list is the number of rows in the index.  (This is the same as the
-** number of rows in the table, except for partial indices.)  The second
-** integer is the average number of rows in the index that have the same
-** value in the first column of the index.  The third integer is the average
-** number of rows in the index that have the same value for the first two
-** columns.  The N-th integer (for N>1) is the average number of rows in 
-** the index which have the same value for the first N-1 columns.  For
-** a K-column index, there will be K+1 integers in the stat column.  If
-** the index is unique, then the last integer will be 1.
-**
-** The list of integers in the stat column can optionally be followed
-** by the keyword "unordered".  The "unordered" keyword, if it is present,
-** must be separated from the last integer by a single space.  If the
-** "unordered" keyword is present, then the query planner assumes that
-** the index is unordered and will not use the index for a range query.
-** 
-** If the sqlite_stat1.idx column is NULL, then the sqlite_stat1.stat
-** column contains a single integer which is the (estimated) number of
-** rows in the table identified by sqlite_stat1.tbl.
-**
-** Format of sqlite_stat2:
-**
-** The sqlite_stat2 is only created and is only used if SQLite is compiled
-** with SQLITE_ENABLE_STAT2 and if the SQLite version number is between
-** 3.6.18 and 3.7.8.  The "stat2" table contains additional information
-** about the distribution of keys within an index.  The index is identified by
-** the "idx" column and the "tbl" column is the name of the table to which
-** the index belongs.  There are usually 10 rows in the sqlite_stat2
-** table for each index.
-**
-** The sqlite_stat2 entries for an index that have sampleno between 0 and 9
-** inclusive are samples of the left-most key value in the index taken at
-** evenly spaced points along the index.  Let the number of samples be S
-** (10 in the standard build) and let C be the number of rows in the index.
-** Then the sampled rows are given by:
-**
-**     rownumber = (i*C*2 + C)/(S*2)
-**
-** For i between 0 and S-1.  Conceptually, the index space is divided into
-** S uniform buckets and the samples are the middle row from each bucket.
-**
-** The format for sqlite_stat2 is recorded here for legacy reference.  This
-** version of SQLite does not support sqlite_stat2.  It neither reads nor
-** writes the sqlite_stat2 table.  This version of SQLite only supports
-** sqlite_stat3.
-**
-** Format for sqlite_stat3:
-**
-** The sqlite_stat3 format is a subset of sqlite_stat4.  Hence, the
-** sqlite_stat4 format will be described first.  Further information
-** about sqlite_stat3 follows the sqlite_stat4 description.
-**
-** Format for sqlite_stat4:
-**
-** As with sqlite_stat2, the sqlite_stat4 table contains histogram data
-** to aid the query planner in choosing good indices based on the values
-** that indexed columns are compared against in the WHERE clauses of
-** queries.
-**
-** The sqlite_stat4 table contains multiple entries for each index.
-** The idx column names the index and the tbl column is the table of the
-** index.  If the idx and tbl columns are the same, then the sample is
-** of the INTEGER PRIMARY KEY.  The sample column is a blob which is the
-** binary encoding of a key from the index.  The nEq column is a
-** list of integers.  The first integer is the approximate number
-** of entries in the index whose left-most column exactly matches
-** the left-most column of the sample.  The second integer in nEq
-** is the approximate number of entries in the index where the
-** first two columns match the first two columns of the sample.
-** And so forth.  nLt is another list of integers that show the approximate
-** number of entries that are strictly less than the sample.  The first
-** integer in nLt contains the number of entries in the index where the
-** left-most column is less than the left-most column of the sample.
-** The K-th integer in the nLt entry is the number of index entries 
-** where the first K columns are less than the first K columns of the
-** sample.  The nDLt column is like nLt except that it contains the 
-** number of distinct entries in the index that are less than the
-** sample.
-**
-** There can be an arbitrary number of sqlite_stat4 entries per index.
-** The ANALYZE command will typically generate sqlite_stat4 tables
-** that contain between 10 and 40 samples which are distributed across
-** the key space, though not uniformly, and which include samples with
-** large nEq values.
-**
-** Format for sqlite_stat3 redux:
-**
-** The sqlite_stat3 table is like sqlite_stat4 except that it only
-** looks at the left-most column of the index.  The sqlite_stat3.sample
-** column contains the actual value of the left-most column instead
-** of a blob encoding of the complete index key as is found in
-** sqlite_stat4.sample.  The nEq, nLt, and nDLt entries of sqlite_stat3
-** all contain just a single integer which is the same as the first
-** integer in the equivalent columns in sqlite_stat4.

-** THREAD SAFETY NOTES:
-**
-**   Once it has been created using backup_init(), a single sqlite3_backup
-**   structure may be accessed via two groups of thread-safe entry points:
-**
-**     * Via the sqlite3_backup_XXX() API function backup_step() and 
-**       backup_finish(). Both these functions obtain the source database
-**       handle mutex and the mutex associated with the source BtShared 
-**       structure, in that order.
-**
-**     * Via the BackupUpdate() and BackupRestart() functions, which are
-**       invoked by the pager layer to report various state changes in
-**       the page cache associated with the source database. The mutex
-**       associated with the source database BtShared structure will always 
-**       be held when either of these functions are invoked.
-**
-**   The other sqlite3_backup_XXX() API functions, backup_remaining() and
-**   backup_pagecount() are not thread-safe functions. If they are called
-**   while some other thread is calling backup_step() or backup_finish(),
-**   the values returned may be invalid. There is no way for a call to
-**   BackupUpdate() or BackupRestart() to interfere with backup_remaining()
-**   or backup_pagecount().
-**
-**   Depending on the SQLite configuration, the database handles and/or
-**   the Btree objects may have their own mutexes that require locking.
-**   Non-sharable Btrees (in-memory databases for example), do not have
-**   associated mutexes.

-*************************************************************************
-** This file implements an object that represents a fixed-length
-** bitmap.  Bits are numbered starting with 1.
-**
-** A bitmap is used to record which pages of a database file have been
-** journalled during a transaction, or which pages have the "dont-write"
-** property.  Usually only a few pages are meet either condition.
-** So the bitmap is usually sparse and has low cardinality.
-** But sometimes (for example when during a DROP of a large table) most
-** or all of the pages in a database can get journalled.  In those cases, 
-** the bitmap becomes dense with high cardinality.  The algorithm needs 
-** to handle both cases well.
-**
-** The size of the bitmap is fixed when the object is created.
-**
-** All bits are clear when the bitmap is created.  Individual bits
-** may be set or cleared one at a time.
-**
-** Test operations are about 100 times more common that set operations.
-** Clear operations are exceedingly rare.  There are usually between
-** 5 and 500 set operations per Bitvec object, though the number of sets can
-** sometimes grow into tens of thousands or larger.  The size of the
-** Bitvec object is the number of pages in the database file at the
-** start of a transaction, and is thus usually less than a few thousand,
-** but can be as large as 2 billion for a really big database.

-** Set bit pgno of the BtShared.pHasContent bitvec. This is called

-** bug caused by the interaction of two useful IO optimizations surrounding
-** free-list leaf pages:
-**
-**   1) When all data is deleted from a page and the page becomes
-**      a free-list leaf page, the page is not written to the database
-**      (as free-list leaf pages contain no meaningful data). Sometimes
-**      such a page is not even journalled (as it will not be modified,
-**      why bother journalling it?).
-**
-**   2) When a free-list leaf page is reused, its content is not read
-**      from the database or written to the journal file (why should it
-**      be, if it is not at all meaningful?).
-**
-** By themselves, these optimizations work fine and provide a handy
-** performance boost to bulk delete or insert operations. However, if
-** a page is moved to the free-list and then reused within the same
-** transaction, a problem comes up. If the page is not journalled when
-** it is moved to the free-list and it is also not journalled when it
-** is extracted from the free-list and reused, then the original data
-** may be lost. In the event of a rollback, it may not be possible
-** to restore the database to its original configuration.
-**
-** The solution is the BtShared.pHasContent bitvec. Whenever a page is 
-** moved to become a free-list leaf page, the corresponding bit is
-** set in the bitvec. Whenever a leaf page is extracted from the free-list,
-** optimization 2 above is omitted if the corresponding bit is already

-** This routine redistributes cells on the iParentIdx'th child of pParent

-** page are used in the balancing, though both siblings might come from one
-** side if the page is the first or last child of its parent. If the page 
-** has fewer than 2 siblings (something which can only happen if the page
-** is a root page or a child of a root page) then all available siblings
-** participate in the balancing.
-**
-** The number of siblings of the page might be increased or decreased by 
-** one or two in an effort to keep pages nearly full but not over full. 
-**
-** Note that when this routine is called, some of the cells on the page
-** might not actually be stored in MemPage.aData[]. This can happen
-** if the page is overfull. This routine ensures that all cells allocated
-** to the page and its siblings fit into MemPage.aData[] before returning.
-**
-** In the course of balancing the page and its siblings, cells may be
-** inserted into or removed from the parent page (pParent). Doing so
-** may cause the parent page to become overfull or underfull. If this
-** happens, it is the responsibility of the caller to invoke the correct
-** balancing routine to fix this problem (see the balance() routine). 
-**
-** If this routine fails for any reason, it might leave the database
-** in a corrupted state. So if this routine fails, the database should
-** be rolled back.
-**
-** The third argument to this function, aOvflSpace, is a pointer to a
-** buffer big enough to hold one page. If while inserting cells into the parent
-** page (pParent) the parent page becomes overfull, this buffer is
-** used to store the parent's overflow cells. Because this function inserts
-** a maximum of four divider cells into the parent page, and the maximum
-** size of a cell stored within an internal node is always less than 1/4
-** of the page-size, the aOvflSpace[] buffer is guaranteed to be large
-** enough for all overflow cells.
-**
-** If aOvflSpace is set to a null pointer, this function returns

-** BTREE_HINT_RANGE  (arguments: Expr*, Mem*)

-**     might be fetched with this cursor.  The Expr* tree may contain
-**     TK_REGISTER nodes that refer to values stored in the array of registers

-**     column of the b-tree of the cursor.  The Expr tree will not contain
-**     any function calls nor subqueries nor references to b-trees other than
-**     the cursor being hinted.
-**
-**     The design of the _RANGE hint is aid b-tree implementations that try
-**     to prefetch content from remote machines - to provide those
-**     implementations with limits on what needs to be prefetched and thereby
-**     reduce network bandwidth.
-**
-** Note that BTREE_HINT_FLAGS with BTREE_BULKLOAD is the only hint used by

-** the SQLite parser and code generator but substitute their own storage
-** engine.

-**
-** The BTREE_BULKLOAD flag is set on index cursors when the index is going
-** to be filled with content that is already in sorted order.
-**
-** The BTREE_SEEK_EQ flag is set on cursors that will get OP_SeekGE or

-** selected will all have the same key.  In other words, the cursor will

-
-/* 
-** Flags passed as the third argument to sqlite3BtreeCursor().
-**
-** For read-only cursors the wrFlag argument is always zero. For read-write
-** cursors it may be set to either (BTREE_WRCSR|BTREE_FORDELETE) or just
-** (BTREE_WRCSR). If the BTREE_FORDELETE bit is set, then the cursor will

-**   * to read values that will be used to create keys that other
-**     BTREE_FORDELETE cursors will seek to and delete.

-** The BTREE_FORDELETE flag is an optimization hint.  It is not used by
-** by this, the native b-tree engine of SQLite, but it is available to
-** alternative storage engines that might be substituted in place of this
-** b-tree system.  For alternative storage engines in which a delete of
-** the main table row automatically deletes corresponding index rows,
-** the FORDELETE flag hint allows those alternative storage engines to
-** skip a lot of work.  Namely:  FORDELETE cursors may treat all SEEK
-** and DELETE operations as no-ops, and any READ operation against a

-*************************************************************************
-** This file implements an external (disk-based) database using BTrees.
-** For a detailed discussion of BTrees, refer to
-**
-**     Donald E. Knuth, THE ART OF COMPUTER PROGRAMMING, Volume 3:
-**     "Sorting And Searching", pages 473-480. Addison-Wesley
-**     Publishing Company, Reading, Massachusetts.
-**
-** The basic idea is that each page of the file contains N database
-** entries and N+1 pointers to subpages.
-**
-**   ----------------------------------------------------------------
-**   |  Ptr(0) | Key(0) | Ptr(1) | Key(1) | ... | Key(N-1) | Ptr(N) |
-**   ----------------------------------------------------------------
-**
-** All of the keys on the page that Ptr(0) points to have values less
-** than Key(0).  All of the keys on page Ptr(1) and its subpages have
-** values greater than Key(0) and less than Key(1).  All of the keys
-** on Ptr(N) and its subpages have values greater than Key(N-1).  And
-** so forth.
-**
-** Finding a particular key requires reading O(log(M)) pages from the 
-** disk where M is the number of entries in the tree.
-**
-** In this implementation, a single file can hold one or more separate 
-** BTrees.  Each BTree is identified by the index of its root page.  The
-** key and data for any entry are combined to form the "payload".  A
-** fixed amount of payload can be carried directly on the database
-** page.  If the payload is larger than the preset amount then surplus
-** bytes are stored on overflow pages.  The payload for an entry
-** and the preceding pointer are combined to form a "Cell".  Each 
-** page has a small header which contains the Ptr(N) pointer and other
-** information such as the size of key and data.
-**
-** FORMAT DETAILS
-**
-** The file is divided into pages.  The first page is called page 1,
-** the second is page 2, and so forth.  A page number of zero indicates
-** "no such page".  The page size can be any power of 2 between 512 and 65536.
-** Each page can be either a btree page, a freelist page, an overflow
-** page, or a pointer-map page.
-**
-** The first page is always a btree page.  The first 100 bytes of the first
-** page contain a special header (the "file header") that describes the file.
-** The format of the file header is as follows:
-**
-**   OFFSET   SIZE    DESCRIPTION
-**      0      16     Header string: "SQLite format 3\000"
-**     16       2     Page size in bytes.  (1 means 65536)
-**     18       1     File format write version

-** The file change counter is incremented when the database is changed
-** This counter allows other processes to know when the file has changed
-** and thus when they need to flush their cache.
-**
-** The max embedded payload fraction is the amount of the total usable
-** space in a page that can be consumed by a single cell for standard
-** B-tree (non-LEAFDATA) tables.  A value of 255 means 100%.  The default
-** is to limit the maximum cell size so that at least 4 cells will fit
-** on one page.  Thus the default max embedded payload fraction is 64.
-**
-** If the payload for a cell is larger than the max payload, then extra
-** payload is spilled to overflow pages.  Once an overflow page is allocated,
-** as many bytes as possible are moved into the overflow pages without letting
-** the cell size drop below the min embedded payload fraction.
-**
-** The min leaf payload fraction is like the min embedded payload fraction
-** except that it applies to leaf nodes in a LEAFDATA tree.  The maximum
-** payload fraction for a LEAFDATA tree is always 100% (or 255) and it
-** not specified in the header.
-**
-** Each btree pages is divided into three sections:  The header, the
-** cell pointer array, and the cell content area.  Page 1 also has a 100-byte
-** file header that occurs before the page header.
-**
-**      |----------------|
-**      | file header    |   100 bytes.  Page 1 only.
-**      |----------------|
-**      | page header    |   8 bytes for leaves.  12 bytes for interior nodes
-**      |----------------|
-**      | cell pointer   |   |  2 bytes per cell.  Sorted order.
-**      | array          |   |  Grows downward
-**      |                |   v
-**      |----------------|
-**      | unallocated    |
-**      | space          |
-**      |----------------|   ^  Grows upwards
-**      | cell content   |   |  Arbitrary order interspersed with freeblocks.
-**      | area           |   |  and free space fragments.
-**      |----------------|
-**
-** The page headers looks like this:
-**
-**   OFFSET   SIZE     DESCRIPTION
-**      0       1      Flags. 1: intkey, 2: zerodata, 4: leafdata, 8: leaf
-**      1       2      byte offset to the first freeblock
-**      3       2      number of cells on this page
-**      5       2      first byte of the cell content area
-**      7       1      number of fragmented free bytes
-**      8       4      Right child (the Ptr(N) value).  Omitted on leaves.
-**
-** The flags define the format of this btree page.  The leaf flag means that
-** this page has no children.  The zerodata flag means that this page carries
-** only keys and no data.  The intkey flag means that the key is an integer
-** which is stored in the key size entry of the cell header rather than in
-** the payload area.
-**
-** The cell pointer array begins on the first byte after the page header.
-** The cell pointer array contains zero or more 2-byte numbers which are
-** offsets from the beginning of the page to the cell content in the cell
-** content area.  The cell pointers occur in sorted order.  The system strives
-** to keep free space after the last cell pointer so that new cells can
-** be easily added without having to defragment the page.
-**
-** Cell content is stored at the very end of the page and grows toward the
-** beginning of the page.
-**
-** Unused space within the cell content area is collected into a linked list of
-** freeblocks.  Each freeblock is at least 4 bytes in size.  The byte offset
-** to the first freeblock is given in the header.  Freeblocks occur in
-** increasing order.  Because a freeblock must be at least 4 bytes in size,
-** any group of 3 or fewer unused bytes in the cell content area cannot
-** exist on the freeblock chain.  A group of 3 or fewer free bytes is called
-** a fragment.  The total number of bytes in all fragments is recorded.
-** in the page header at offset 7.
-**
-**    SIZE    DESCRIPTION
-**      2     Byte offset of the next freeblock
-**      2     Bytes in this freeblock
-**
-** Cells are of variable length.  Cells are stored in the cell content area at
-** the end of the page.  Pointers to the cells are in the cell pointer array
-** that immediately follows the page header.  Cells is not necessarily
-** contiguous or in order, but cell pointers are contiguous and in order.
-**
-** Cell content makes use of variable length integers.  A variable
-** length integer is 1 to 9 bytes where the lower 7 bits of each 
-** byte are used.  The integer consists of all bytes that have bit 8 set and
-** the first byte with bit 8 clear.  The most significant byte of the integer
-** appears first.  A variable-length integer may not be more than 9 bytes long.
-** As a special case, all 8 bytes of the 9th byte are used as data.  This
-** allows a 64-bit integer to be encoded in 9 bytes.
-**
-**    0x00                      becomes  0x00000000
-**    0x7f                      becomes  0x0000007f
-**    0x81 0x00                 becomes  0x00000080
-**    0x82 0x00                 becomes  0x00000100
-**    0x80 0x7f                 becomes  0x0000007f
-**    0x8a 0x91 0xd1 0xac 0x78  becomes  0x12345678
-**    0x81 0x81 0x81 0x81 0x01  becomes  0x10204081
-**
-** Variable length integers are used for rowids and to hold the number of
-** bytes of key and data in a btree cell.
-**
-** The content of a cell looks like this:
-**
-**    SIZE    DESCRIPTION
-**      4     Page number of the left child. Omitted if leaf flag is set.
-**     var    Number of bytes of data. Omitted if the zerodata flag is set.
-**     var    Number of bytes of key. Or the key itself if intkey flag is set.
-**      *     Payload
-**      4     First page of the overflow chain.  Omitted if no overflow
-**
-** Overflow pages form a linked list.  Each page except the last is completely
-** filled with data (pagesize - 4 bytes).  The last page can have as little
-** as 1 byte of data.
-**
-**    SIZE    DESCRIPTION
-**      4     Page number of next overflow page
-**      *     Data
-**
-** Freelist pages come in two subtypes: trunk pages and leaf pages.  The
-** file header points to the first in a linked list of trunk page.  Each trunk
-** page points to multiple leaf pages.  The content of a leaf page is
-** unspecified.  A trunk page looks like this:
-**
-**    SIZE    DESCRIPTION
-**      4     Page number of next trunk page
-**      4     Number of leaf pointers on this page
-**      *     zero or more pages numbers of leaves

-**
-**   (1) START     At the beginning or end of an SQL statement.  This routine

-**                 in any other state.
-**
-**   (2) NORMAL    We are in the middle of statement which ends with a single
-**                 semicolon.
-**
-**   (3) EXPLAIN   The keyword EXPLAIN has been seen at the beginning of 
-**                 a statement.
-**
-**   (4) CREATE    The keyword CREATE has been seen at the beginning of a
-**                 statement, possibly preceded by EXPLAIN and/or followed by
-**                 TEMP or TEMPORARY
-**
-**   (5) TRIGGER   We are in the middle of a trigger definition that must be
-**                 ended by a semicolon, the keyword END, and another semicolon.
-**
-**   (6) SEMI      We've seen the first semicolon in the ";END;" that occurs at
-**                 the end of a trigger definition.
-**
-**   (7) END       We've seen the ";END" of the ";END;" that occurs at the end
-**                 of a trigger definition.
-**
-** Transitions between states above are determined by tokens extracted
-** from the input.  The following tokens are significant:
-**
-**   (0) tkSEMI      A semicolon.
-**   (1) tkWS        Whitespace.
-**   (2) tkOTHER     Any other SQL token.
-**   (3) tkEXPLAIN   The "explain" keyword.
-**   (4) tkCREATE    The "create" keyword.
-**   (5) tkTEMP      The "temp" or "temporary" keyword.
-**   (6) tkTRIGGER   The "trigger" keyword.
-**   (7) tkEND       The "end" keyword.
-**
-** Whitespace never causes a state transition and is always ignored.
-** This means that a SQL string of all whitespace is invalid.
-**
-** If we compile with SQLITE_OMIT_TRIGGER, all of the computation needed
-** to recognize the end of a trigger can be omitted.  All we have to do

-*************************************************************************
-** This file contains the C functions that implement date and time
-** functions for SQLite.  
-**
-** There is only one exported symbol in this file - the function
-** sqlite3RegisterDateTimeFunctions() found at the bottom of the file.
-** All other code has file scope.
-**
-** SQLite processes all times and dates as julian day numbers.  The
-** dates and times are stored as the number of days since noon
-** in Greenwich on November 24, 4714 B.C. according to the Gregorian
-** calendar system. 
-**
-** 1970-01-01 00:00:00 is JD 2440587.5
-** 2000-01-01 00:00:00 is JD 2451544.5
-**
-** This implementation requires years to be expressed as a 4-digit number
-** which means that only dates between 0000-01-01 and 9999-12-31 can
-** be represented, even though julian day numbers allow a much wider
-** range of dates.
-**
-** The Gregorian calendar system is used for all dates and times,
-** even those that predate the Gregorian calendar.  Historians usually
-** use the julian calendar for dates prior to 1582-10-15 and for some
-** dates afterwards, depending on locale.  Beware of this difference.
-**
-** The conversion algorithms are implemented based on descriptions
-** in the following text:

-** Example:  To translate an ISO-8601 date YYYY-MM-DD, the format would

-******************************************************************************
-**
-** This file contains an implementation of the "sqlite_dbpage" virtual table.
-**
-** The sqlite_dbpage virtual table is used to read or write whole raw
-** pages of the database file.  The pager interface is used so that 
-** uncommitted changes and changes recorded in the WAL file are correctly
-** retrieved.
-**
-** Usage example:
-**
-**    SELECT data FROM sqlite_dbpage('aux1') WHERE pgno=123;
-**
-** This is an eponymous virtual table so it does not need to be created before
-** use.  The optional argument to the sqlite_dbpage() table name is the
-** schema for the database file that is to be read.  The default schema is
-** "main".
-**
-** The data field of sqlite_dbpage table can be updated.  The new
-** value must be a BLOB which is the correct page size, otherwise the
-** update fails.  Rows may not be deleted or inserted.

-******************************************************************************
-**
-** This file contains an implementation of the "dbstat" virtual table.
-**
-** The dbstat virtual table is used to extract low-level formatting
-** information from an SQLite database in order to implement the
-** "sqlite3_analyzer" utility.  See the ../tool/spaceanal.tcl script
-** for an example implementation.
-**
-** Additional information is available on the "dbstat.html" page of the
-** official SQLite documentation.

-** Page paths:
-** 
-**   The value of the 'path' column describes the path taken from the 
-**   root-node of the b-tree structure to each page. The value of the 
-**   root-node path is '/'.
-**
-**   The value of the path for the left-most child page of the root of
-**   a b-tree is '/000/'. (Btrees store content ordered from left to right
-**   so the pages to the left have smaller keys than the pages to the right.)
-**   The next to left-most child of the root page is
-**   '/001', and so on, each sibling page identified by a 3-digit hex 
-**   value. The children of the 451st left-most sibling have paths such
-**   as '/1c2/000/, '/1c2/001/' etc.
-**
-**   Overflow pages are specified by appending a '+' character and a 
-**   six-digit hexadecimal value to the path to the cell they are linked
-**   from. For example, the three overflow pages in a chain linked from 
-**   the left-most cell of the 450th child of the root page are identified
-**   by the paths:
-**
-**      '/1c2/000+000000'         // First page in overflow chain
-**      '/1c2/000+000001'         // Second page in overflow chain
-**      '/1c2/000+000002'         // Third page in overflow chain
-**
-**   If the paths are sorted using the BINARY collation sequence, then
-**   the overflow pages associated with a cell will appear earlier in the
-**   sort-order than its child page:
-**
-**      '/1c2/000/'               // Left-most child of 451st child of root

-** This routine generates VDBE code that causes a single row of a

-**
-** Preconditions:
-**
-**   1.  iDataCur is an open cursor on the btree that is the canonical data
-**       store for the table.  (This will be either the table itself,
-**       in the case of a rowid table, or the PRIMARY KEY index in the case
-**       of a WITHOUT ROWID table.)
-**
-**   2.  Read/write cursors for all indices of pTab must be open as
-**       cursor number iIdxCur+i for the i-th index.
-**
-**   3.  The primary key for the row to be deleted must be stored in a
-**       sequence of nPk memory cells starting at iPk.  If nPk==0 that means
-**       that a search record formed from OP_MakeRecord is contained in the
-**       single memory location iPk.
-**
-** eMode:
-**   Parameter eMode may be passed either ONEPASS_OFF (0), ONEPASS_SINGLE, or
-**   ONEPASS_MULTI.  If eMode is not ONEPASS_OFF, then the cursor
-**   iDataCur already points to the row to delete. If eMode is ONEPASS_OFF
-**   then this function must seek iDataCur to the entry identified by iPk
-**   and nPk before reading from it.
-**
-**   If eMode is ONEPASS_MULTI, then this call is being made as part
-**   of a ONEPASS delete that affects multiple rows. In this case, if 
-**   iIdxNoSeek is a valid cursor number (>=0) and is not the same as
-**   iDataCur, then its position should be preserved following the delete
-**   operation. Or, if iIdxNoSeek is not a valid cursor number, the
-**   position of iDataCur should be preserved instead.
-**
-** iIdxNoSeek:
-**   If iIdxNoSeek is a valid cursor number (>=0) not equal to iDataCur,

-** This function is used by the implementation of the IN (...) operator.
-** The pX parameter is the expression on the RHS of the IN operator, which
-** might be either a list of expressions or a subquery.
-**
-** The job of this routine is to find or create a b-tree object that can
-** be used either to test for membership in the RHS set or to iterate through
-** all members of the RHS set, skipping duplicates.
-**
-** A cursor is opened on the b-tree object that is the RHS of the IN operator
-** and pX->iTable is set to the index of that cursor.
-**
-** The returned value of this function indicates the b-tree type, as follows:
-**
-**   IN_INDEX_ROWID      - The cursor was opened on a database table.
-**   IN_INDEX_INDEX_ASC  - The cursor was opened on an ascending index.
-**   IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
-**   IN_INDEX_EPH        - The cursor was opened on a specially created and
-**                         populated epheremal table.
-**   IN_INDEX_NOOP       - No cursor was allocated.  The IN operator must be
-**                         implemented as a sequence of comparisons.
-**
-** An existing b-tree might be used if the RHS expression pX is a simple
-** subquery such as:
-**
-**     SELECT <column1>, <column2>... FROM <table>
-**
-** If the RHS of the IN operator is a list or a more complex subquery, then
-** an ephemeral table might need to be generated from the RHS and then
-** pX->iTable made to point to the ephemeral table instead of an
-** existing table.
-**
-** The inFlags parameter must contain, at a minimum, one of the bits
-** IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both.  If inFlags contains
-** IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast
-** membership test.  When the IN_INDEX_LOOP bit is set, the IN index will
-** be used to loop over all values of the RHS of the IN operator.
-**
-** When IN_INDEX_LOOP is used (and the b-tree will be used to iterate
-** through the set members) then the b-tree must not contain duplicates.
-** An epheremal table will be created unless the selected columns are guaranteed
-** to be unique - either because it is an INTEGER PRIMARY KEY or due to
-** a UNIQUE constraint or index.
-**
-** When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used 
-** for fast set membership tests) then an epheremal table must 
-** be used unless <columns> is a single INTEGER PRIMARY KEY column or an 
-** index can be found with the specified <columns> as its left-most.
-**
-** If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and
-** if the RHS of the IN operator is a list (not a subquery) then this
-** routine might decide that creating an ephemeral b-tree for membership
-** testing is too expensive and return IN_INDEX_NOOP.  In that case, the
-** calling routine should implement the IN operator using a sequence
-** of Eq or Ne comparison operations.
-**
-** When the b-tree is being used for membership tests, the calling function
-** might need to know whether or not the RHS side of the IN operator
-** contains a NULL.  If prRhsHasNull is not a NULL pointer and 
-** if there is any chance that the (...) might contain a NULL value at
-** runtime, then a register is allocated and the register number written
-** to *prRhsHasNull. If there is no chance that the (...) contains a
-** NULL value, then *prRhsHasNull is left unchanged.
-**
-** If a register is allocated and its location stored in *prRhsHasNull, then
-** the value in that register will be NULL if the b-tree contains one or more
-** NULL values, and it will be some non-NULL value if the b-tree contains no
-** NULL values.
-**
-** If the aiMap parameter is not NULL, it must point to an array containing
-** one element for each column returned by the SELECT statement on the RHS
-** of the IN(...) operator. The i'th entry of the array is populated with the
-** offset of the index column that matches the i'th column returned by the
-** SELECT. For example, if the expression and selected index are:
-**
-**   (?,?,?) IN (SELECT a, b, c FROM t1)
-**   CREATE INDEX i1 ON t1(b, c, a);
-**
-** then aiMap[] is populated with {2, 0, 1}.

-** Deferred and Immediate FKs
-** --------------------------
-**
-** Foreign keys in SQLite come in two flavours: deferred and immediate.
-** If an immediate foreign key constraint is violated,
-** SQLITE_CONSTRAINT_FOREIGNKEY is returned and the current
-** statement transaction rolled back. If a 
-** deferred foreign key constraint is violated, no action is taken 
-** immediately. However if the application attempts to commit the 
-** transaction before fixing the constraint violation, the attempt fails.
-**
-** Deferred constraints are implemented using a simple counter associated
-** with the database handle. The counter is set to zero each time a 
-** database transaction is opened. Each time a statement is executed 
-** that causes a foreign key violation, the counter is incremented. Each
-** time a statement is executed that removes an existing violation from
-** the database, the counter is decremented. When the transaction is
-** committed, the commit fails if the current value of the counter is
-** greater than zero. This scheme has two big drawbacks:
-**
-**   * When a commit fails due to a deferred foreign key constraint, 
-**     there is no way to tell which foreign constraint is not satisfied,
-**     or which row it is not satisfied for.
-**
-**   * If the database contains foreign key violations when the 
-**     transaction is opened, this may cause the mechanism to malfunction.
-**
-** Despite these problems, this approach is adopted as it seems simpler
-** than the alternatives.
-**
-** INSERT operations:
-**
-**   I.1) For each FK for which the table is the child table, search
-**        the parent table for a match. If none is found increment the
-**        constraint counter.
-**
-**   I.2) For each FK for which the table is the parent table, 
-**        search the child table for rows that correspond to the new
-**        row in the parent table. Decrement the counter for each row
-**        found (as the constraint is now satisfied).
-**
-** DELETE operations:
-**
-**   D.1) For each FK for which the table is the child table, 
-**        search the parent table for a row that corresponds to the 
-**        deleted row in the child table. If such a row is not found, 
-**        decrement the counter.
-**
-**   D.2) For each FK for which the table is the parent table, search 
-**        the child table for rows that correspond to the deleted row 
-**        in the parent table. For each found increment the counter.
-**
-** UPDATE operations:
-**
-**   An UPDATE command requires that all 4 steps above are taken, but only
-**   for FK constraints for which the affected columns are actually 
-**   modified (values must be compared at runtime).
-**
-** Note that I.1 and D.1 are very similar operations, as are I.2 and D.2.
-** This simplifies the implementation a bit.
-**
-** For the purposes of immediate FK constraints, the OR REPLACE conflict
-** resolution is considered to delete rows before the new row is inserted.
-** If a delete caused by OR REPLACE violates an FK constraint, an exception
-** is thrown, even if the FK constraint would be satisfied after the new 
-** row is inserted.
-**
-** Immediate constraints are usually handled similarly. The only difference 
-** is that the counter used is stored as part of each individual statement
-** object (struct Vdbe). If, after the statement has run, its immediate
-** constraint counter is greater than zero,
-** it returns SQLITE_CONSTRAINT_FOREIGNKEY
-** and the statement transaction is rolled back. An exception is an INSERT
-** statement that inserts a single row only (no triggers). In this case,
-** instead of using a counter, an exception is thrown immediately if the
-** INSERT violates a foreign key constraint. This is necessary as such
-** an INSERT does not open a statement transaction.
-**
-** TODO: How should dropping a table be handled? How should renaming a 
-** table be handled?
-**
-**
-** Query API Notes
-** ---------------
-**
-** Before coding an UPDATE or DELETE row operation, the code-generator
-** for those two operations needs to know whether or not the operation
-** requires any FK processing and, if so, which columns of the original
-** row are required by the FK processing VDBE code (i.e. if FKs were
-** implemented using triggers, which of the old.* columns would be 
-** accessed). No information is required by the code-generator before
-** coding an INSERT operation. The functions used by the UPDATE/DELETE
-** generation code to query for this information are:
-**
-**   sqlite3FkRequired() - Test to see if FK processing is required.
-**   sqlite3FkOldmask()  - Query for the set of required old.* columns.
-**
-**
-** Externally accessible module functions
-** --------------------------------------
-**
-**   sqlite3FkCheck()    - Check for foreign key violations.
-**   sqlite3FkActions()  - Code triggers for ON UPDATE/ON DELETE actions.
-**   sqlite3FkDelete()   - Delete an FKey structure.

-** VDBE Calling Convention
-** -----------------------
-**
-** Example:
-**
-**   For the following INSERT statement:
-**
-**     CREATE TABLE t1(a, b INTEGER PRIMARY KEY, c);
-**     INSERT INTO t1 VALUES(1, 2, 3.1);
-**
-**   Register (x):        2    (type integer)
-**   Register (x+1):      1    (type integer)
-**   Register (x+2):      NULL (type NULL)
-**   Register (x+3):      3.1  (type real)

-/*
-** A foreign key constraint requires that the key columns in the parent
-** table are collectively subject to a UNIQUE or PRIMARY KEY constraint.
-** Given that pParent is the parent table for foreign key constraint pFKey, 
-** search the schema for a unique index on the parent key columns. 
-**
-** If successful, zero is returned. If the parent key is an INTEGER PRIMARY 
-** KEY column, then output variable *ppIdx is set to NULL. Otherwise, *ppIdx 
-** is set to point to the unique index. 
-** 
-** If the parent key consists of a single column (the foreign key constraint
-** is not a composite foreign key), output variable *paiCol is set to NULL.
-** Otherwise, it is set to point to an allocated array of size N, where
-** N is the number of columns in the parent key. The first element of the
-** array is the index of the child table column that is mapped by the FK
-** constraint to the parent table column stored in the left-most column
-** of index *ppIdx. The second element of the array is the index of the
-** child table column that corresponds to the second left-most column of
-** *ppIdx, and so on.
-**
-** If the required index cannot be found, either because:
-**
-**   1) The named parent key columns do not exist, or
-**
-**   2) The named parent key columns do exist, but are not subject to a
-**      UNIQUE or PRIMARY KEY constraint, or
-**
-**   3) No parent key columns were provided explicitly as part of the
-**      foreign key definition, and the parent table does not have a

-**
-**   4) No parent key columns were provided explicitly as part of the
-**      foreign key definition, and the PRIMARY KEY of the parent table 
-**      consists of a different number of columns to the child key in 
-**      the child table.

-/*
-** This function is called when an UPDATE or DELETE operation is being 
-** compiled on table pTab, which is the parent table of foreign-key pFKey.
-** If the current operation is an UPDATE, then the pChanges parameter is
-** passed a pointer to the list of columns being modified. If it is a
-** DELETE, pChanges is passed a NULL pointer.
-**
-** It returns a pointer to a Trigger structure containing a trigger
-** equivalent to the ON UPDATE or ON DELETE action specified by pFKey.
-** If the action is "NO ACTION" or "RESTRICT", then a NULL pointer is
-** returned (these actions require no special handling by the triggers
-** sub-system, code for them is created by fkScanChildren()).
-**
-** For example, if pFKey is the foreign key and pTab is table "p" in 
-** the following schema:
-**
-**   CREATE TABLE p(pk PRIMARY KEY);
-**   CREATE TABLE c(ck REFERENCES p ON DELETE CASCADE);
-**
-** then the returned trigger structure is equivalent to:
-**
-**   CREATE TRIGGER ... DELETE ON p BEGIN
-**     DELETE FROM c WHERE ck = old.pk;
-**   END;
-**
-** The returned pointer is cached as part of the foreign key object. It
-** is eventually freed along with the rest of the foreign key object by 
-** sqlite3FkDelete().

-** case. i.e. if the character is a lower-case ASCII character.
-** If x is a lower-case ASCII character, then its upper-case equivalent

-**   (x & ~(map[x]&0x20))
-**
-** The equivalent of tolower() is implemented using the sqlite3UpperToLower[]
-** array. tolower() is used more often than toupper() by SQLite.
-**
-** Bit 0x40 is set if the character is non-alphanumeric and can be used in an 
-** SQLite identifier.  Identifiers are alphanumerics, "_", "$", and any
-** non-ASCII UTF character. Hence the test for whether or not a character is

-IN-Operator Implementation Notes
-================================
-
-## Definitions:
-
-An IN operator has one of the following formats:
-
->
-     x IN (y1,y2,y3,...,yN)
-     x IN (subquery)
-
-The "x" is referred to as the LHS (left-hand side).  The list or subquery
-on the right is called the RHS (right-hand side).  If the RHS is a list
-it must be a non-empty list.  But if the RHS is a subquery, it can be an
-empty set.
-
-The LHS can be a scalar (a single quantity) or a vector (a list of
-two or or more values) or a subquery that returns one or more columns.
-We use the term "vector" to mean an actually list of values or a
-subquery that returns two or more columns.  An isolated value or
-a subquery that returns a single columns is called a scalar.
-
-The RHS can be a subquery that returns a single column, a subquery
-that returns two or more columns, or a list of scalars.  It is not
-currently support for the RHS to be a list of vectors.
-
-The number of columns for LHS must match the number of columns for
-the RHS.  If the RHS is a list of values, then the LHS must be a 
-scalar.  If the RHS is a subquery returning N columns, then the LHS
-must be a vector of size N.
-
-NULL values can occur in either or both of the LHS and RHS.
-If the LHS contains only
-NULL values then we say that it is a "total-NULL".  If the LHS contains
-some NULL values and some non-NULL values, then it is a "partial-NULL".
-For a scalar, there is no difference between a partial-NULL and a total-NULL.
-The RHS is a partial-NULL if any row contains a NULL value.  The RHS is
-a total-NULL if it contains one or more rows that contain only NULL values.
-The LHS is called "non-NULL" if it contains no NULL values.  The RHS is
-called "non-NULL" if it contains no NULL values in any row.
-
-The result of an IN operator is one of TRUE, FALSE, or NULL.  A NULL result
-means that it cannot be determined if the LHS is contained in the RHS due
-to the presence of NULL values.  In some contexts (for example, when the IN
-operator occurs in a WHERE clause)
-the system only needs a binary result: TRUE or NOT-TRUE.  One can also
-to define a binary result of FALSE and NOT-FALSE, but
-it turns out that no extra optimizations are possible in that case, so if
-the FALSE/NOT-FALSE binary is needed, we have to compute the three-state
-TRUE/FALSE/NULL result and then combine the TRUE and NULL values into 
-NOT-FALSE.
-
-A "NOT IN" operator is computed by first computing the equivalent IN
-operator, then interchanging the TRUE and FALSE results.
-
-## Simple Full-Scan Algorithm
-
-The following algorithm always compute the correct answer.  However, this
-algorithm is suboptimal, especially if there are many rows on the RHS.
-
-  1.  Set the null-flag to false
-  2.  For each row in the RHS:
-      <ol type='a'>
-      <li>  Compare the LHS against the RHS
-      <li>  If the LHS exactly matches the RHS, immediately return TRUE
-      <li>  If the comparison result is NULL, set the null-flag to true
-      </ol>
-  3.  If the null-flag is true, return NULL.
-  4.  Return FALSE
-
-## Optimized Algorithm
-
-The following procedure computes the same answer as the simple full-scan
-algorithm, though it does so with less work in the common case.  This
-is the algorithm that is implemented in SQLite.
-
-  1.  If the RHS is a constant list of length 1 or 2, then rewrite the
-      IN operator as a simple expression.  Implement
-
-            x IN (y1,y2)
-
-      as if it were
-
-            x=y1 OR x=y2
-
-      This is the INDEX_NOOP optimization and is only undertaken if the
-      IN operator is used for membership testing.  If the IN operator is
-      driving a loop, then skip this step entirely.
-
-  2.  Check the LHS to see if it is a partial-NULL and if it is, jump
-      ahead to step 5.
-
-  3.  Do a binary search of the RHS using the LHS as a probe.  If
-      an exact match is found, return TRUE.
-
-  4.  If the RHS is non-NULL then return FALSE.
-
-  5.  If we do not need to distinguish between FALSE and NULL,
-      then return FALSE.
-  
-  6.  For each row in the RHS, compare that row against the LHS and
-      if the result is NULL, immediately return NULL.  In the case
-      of a scalar IN operator, we only need to look at the very first
-      row the RHS because for a scalar RHS, all NULLs will always come 
-      first.  If the RHS is empty, this step is a no-op.
-
-  7.  Return FALSE.

-** This routine is called to handle SQL of the following forms:
-**
-**    insert into TABLE (IDLIST) values(EXPRLIST),(EXPRLIST),...
-**    insert into TABLE (IDLIST) select
-**    insert into TABLE (IDLIST) default values
-**
-** The IDLIST following the table name is always optional.  If omitted,
-** then a list of all (non-hidden) columns for the table is substituted.
-** The IDLIST appears in the pColumn parameter.  pColumn is NULL if IDLIST
-** is omitted.
-**
-** For the pSelect parameter holds the values to be inserted for the
-** first two forms shown above.  A VALUES clause is really just short-hand
-** for a SELECT statement that omits the FROM clause and everything else
-** that follows.  If the pSelect parameter is NULL, that means that the
-** DEFAULT VALUES form of the INSERT statement is intended.
-**
-** The code generated follows one of four templates.  For a simple
-** insert with data coming from a single-row VALUES clause, the code executes
-** once straight down through.  Pseudo-code follows (we call this
-** the "1st template"):
-**
-**         open write cursor to <table> and its indices
-**         put VALUES clause expressions into registers
-**         write the resulting record into <table>
-**         cleanup
-**
-** The three remaining templates assume the statement is of the form
-**
-**   INSERT INTO <table> SELECT ...
-**
-** If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
-** in other words if the SELECT pulls all columns from a single table
-** and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
-** if <table2> and <table1> are distinct tables but have identical
-** schemas, including all the same indices, then a special optimization
-** is invoked that copies raw records from <table2> over to <table1>.
-** See the xferOptimization() function for the implementation of this
-** template.  This is the 2nd template.
-**
-**         open a write cursor to <table>
-**         open read cursor on <table2>
-**         transfer all records in <table2> over to <table>
-**         close cursors
-**         foreach index on <table>
-**           open a write cursor on the <table> index
-**           open a read cursor on the corresponding <table2> index
-**           transfer all records from the read to the write cursors
-**           close cursors
-**         end foreach
-**
-** The 3rd template is for when the second template does not apply
-** and the SELECT clause does not read from <table> at any time.
-** The generated code follows this template:
-**
-**         X <- A
-**         goto B
-**      A: setup for the SELECT
-**         loop over the rows in the SELECT
-**           load values into registers R..R+n
-**           yield X
-**         end loop
-**         cleanup after the SELECT
-**         end-coroutine X
-**      B: open write cursor to <table> and its indices
-**      C: yield X, at EOF goto D
-**         insert the select result into <table> from R..R+n
-**         goto C
-**      D: cleanup
-**
-** The 4th template is used if the insert statement takes its
-** values from a SELECT but the data is being inserted into a table
-** that is also read as part of the SELECT.  In the third form,
-** we have to use an intermediate table to store the results of
-** the select.  The template is like this:
-**
-**         X <- A
-**         goto B
-**      A: setup for the SELECT
-**         loop over the tables in the SELECT
-**           load value into register R..R+n
-**           yield X
-**         end loop
-**         cleanup after the SELECT
-**         end co-routine R
-**      B: open temp table
-**      L: yield X, at EOF goto M
-**         insert row from R..R+n into temp table
-**         goto L
-**      M: open write cursor to <table> and its indices
-**         rewind temp table
-**      C: loop over rows of intermediate table
-**           transfer values form intermediate table into <table>
-**         end loop
-**      D: cleanup

-** Generate code to do constraint checks prior to an INSERT or an UPDATE

-**
-** The regNewData parameter is the first register in a range that contains
-** the data to be inserted or the data after the update.  There will be
-** pTab->nCol+1 registers in this range.  The first register (the one
-** that regNewData points to) will contain the new rowid, or NULL in the
-** case of a WITHOUT ROWID table.  The second register in the range will
-** contain the content of the first table column.  The third register will
-** contain the content of the second table column.  And so forth.
-**
-** The regOldData parameter is similar to regNewData except that it contains
-** the data prior to an UPDATE rather than afterwards.  regOldData is zero
-** for an INSERT.  This routine can distinguish between UPDATE and INSERT by
-** checking regOldData for zero.
-**
-** For an UPDATE, the pkChng boolean is true if the true primary key (the
-** rowid for a normal table or the PRIMARY KEY for a WITHOUT ROWID table)
-** might be modified by the UPDATE.  If pkChng is false, then the key of
-** the iDataCur content table is guaranteed to be unchanged by the UPDATE.
-**
-** For an INSERT, the pkChng boolean indicates whether or not the rowid
-** was explicitly specified as part of the INSERT statement.  If pkChng
-** is zero, it means that the either rowid is computed automatically or
-** that the table is a WITHOUT ROWID table and has no rowid.  On an INSERT,
-** pkChng will only be true if the INSERT statement provides an integer
-** value for either the rowid column or its INTEGER PRIMARY KEY alias.
-**
-** The code generated by this routine will store new index entries into
-** registers identified by aRegIdx[].  No index entry is created for
-** indices where aRegIdx[i]==0.  The order of indices in aRegIdx[] is
-** the same as the order of indices on the linked list of indices
-** at pTab->pIndex.
-**
-** The caller must have already opened writeable cursors on the main
-** table and all applicable indices (that is to say, all indices for which
-** aRegIdx[] is not zero).  iDataCur is the cursor for the main table when
-** inserting or updating a rowid table, or the cursor for the PRIMARY KEY
-** index when operating on a WITHOUT ROWID table.  iIdxCur is the cursor
-** for the first index in the pTab->pIndex list.  Cursors for other indices
-** are at iIdxCur+N for the N-th element of the pTab->pIndex list.
-**
-** This routine also generates code to check constraints.  NOT NULL,
-** CHECK, and UNIQUE constraints are all checked.  If a constraint fails,
-** then the appropriate action is performed.  There are five possible
-** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
-**
-**  Constraint type  Action       What Happens

-**                                return code of SQLITE_CONSTRAINT.
-**
-**  any              ABORT        Back out changes from the current command
-**                                only (do not do a complete rollback) then
-**                                cause sqlite3_step() to return immediately
-**                                with SQLITE_CONSTRAINT.
-**
-**  any              FAIL         Sqlite3_step() returns immediately with a
-**                                return code of SQLITE_CONSTRAINT.  The
-**                                transaction is not rolled back and any
-**                                changes to prior rows are retained.
-**
-**  any              IGNORE       The attempt in insert or update the current
-**                                row is skipped, without throwing an error.
-**                                Processing continues with the next row.
-**                                (There is an immediate jump to ignoreDest.)
-**
-**  NOT NULL         REPLACE      The NULL value is replace by the default
-**                                value for that column.  If the default value
-**                                is NULL, the action is the same as ABORT.
-**
-**  UNIQUE           REPLACE      The other row that conflicts with the row
-**                                being inserted is removed.
-**
-**  CHECK            REPLACE      Illegal.  The results in an exception.
-**
-** Which action to take is determined by the overrideError parameter.
-** Or if overrideError==OE_Default, then the pParse->onError parameter
-** is used.  Or if pParse->onError==OE_Default then the onError value

-** This file contains the C functions that implement a memory

-**
-** This version of the memory allocation subsystem omits all
-** use of malloc(). The SQLite user supplies a block of memory
-** before calling sqlite3_initialize() from which allocations
-** are made and returned by the xMalloc() and xRealloc() 
-** implementations. Once sqlite3_initialize() has been called,
-** the amount of memory available to SQLite is fixed and cannot
-** be changed.
-**
-** This version of the memory allocation subsystem is included
-** in the build only if SQLITE_ENABLE_MEMSYS3 is defined.

-** This version of the memory allocator is only built into the library
-** SQLITE_ENABLE_MEMSYS3 is defined. Defining this symbol does not
-** mean that the library will use a memory-pool by default, just that
-** it is available. The mempool allocator is activated by calling
-** sqlite3_config().

-/*
-** A memory allocation (also called a "chunk") consists of two or 
-** more blocks where each block is 8 bytes.  The first 8 bytes are 
-** a header that is not returned to the user.
-**
-** A chunk is two or more blocks that is either checked out or
-** free.  The first block has format u.hdr.  u.hdr.size4x is 4 times the
-** size of the allocation in blocks if the allocation is free.
-** The u.hdr.size4x&1 bit is true if the chunk is checked out and
-** false if the chunk is on the freelist.  The u.hdr.size4x&2 bit
-** is true if the previous chunk is checked out and false if the
-** previous chunk is free.  The u.hdr.prevSize field is the size of
-** the previous chunk in blocks if the previous chunk is on the
-** freelist. If the previous chunk is checked out, then
-** u.hdr.prevSize can be part of the data for that chunk and should
-** not be read or written.
-**
-** We often identify a chunk by its index in mem3.aPool[].  When
-** this is done, the chunk index refers to the second block of
-** the chunk.  In this way, the first chunk has an index of 1.
-** A chunk index of 0 means "no such chunk" and is the equivalent
-** of a NULL pointer.
-**
-** The second block of free chunks is of the form u.list.  The
-** two fields form a double-linked list of chunks of related sizes.
-** Pointers to the head of the list are stored in mem3.aiSmall[] 
-** for smaller chunks and mem3.aiHash[] for larger chunks.
-**
-** The second block of a chunk is user data if the chunk is checked 
-** out.  If a chunk is checked out, the user data may extend into
-** the u.hdr.prevSize value of the following chunk.

-*************************************************************************
-** This file contains the C functions that implement a memory
-** allocation subsystem for use by SQLite. 
-**
-** This version of the memory allocation subsystem omits all
-** use of malloc(). The application gives SQLite a block of memory
-** before calling sqlite3_initialize() from which allocations
-** are made and returned by the xMalloc() and xRealloc() 
-** implementations. Once sqlite3_initialize() has been called,
-** the amount of memory available to SQLite is fixed and cannot
-** be changed.
-**
-** This version of the memory allocation subsystem is included
-** in the build only if SQLITE_ENABLE_MEMSYS5 is defined.
-**
-** This memory allocator uses the following algorithm:
-**
-**   1.  All memory allocation sizes are rounded up to a power of 2.
-**
-**   2.  If two adjacent free blocks are the halves of a larger block,
-**       then the two blocks are coalesced into the single larger block.
-**
-**   3.  New memory is allocated from the first available free block.
-**
-** This algorithm is described in: J. M. Robson. "Bounds for Some Functions
-** Concerning Dynamic Storage Allocation". Journal of the Association for
-** Computing Machinery, Volume 21, Number 8, July 1974, pages 491-499.
-** 
-** Let n be the size of the largest allocation divided by the minimum
-** allocation size (after rounding all sizes up to a power of 2.)  Let M
-** be the maximum amount of memory ever outstanding at one time.  Let
-** N be the total amount of memory available for allocation.  Robson
-** proved that this memory allocator will never breakdown due to 
-** fragmentation as long as the following constraint holds:
-**
-**      N >=  M*(1 + log2(n)/2) - n + 1
-**
-** The sqlite3_status() logic tracks the maximum values of n and M so
-** that an application can, at any time, verify this constraint.

-**
-** Update:  The in-memory journal is also used to temporarily cache
-** smaller journals that are not critical for power-loss recovery.
-** For example, statement journals that are not too big will be held
-** entirely in memory, thus reducing the number of file I/O calls, and
-** more importantly, reducing temporary file creation events.  If these
-** journals become too large for memory, they are spilled to disk.  But
-** in the common case, they are usually small and no file I/O needs to

-** The sqlite3_mutex_alloc() routine allocates a new

-** </ul>

-** The first two constants cause sqlite3_mutex_alloc() to create
-** a new mutex.  The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
-** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to.  But SQLite will only request a recursive mutex in
-** cases where it really needs one.  If a faster non-recursive mutex
-** implementation is available on the host platform, the mutex subsystem
-** might return such a mutex in response to SQLITE_MUTEX_FAST.
-**
-** The other allowed parameters to sqlite3_mutex_alloc() each return
-** a pointer to a static preexisting mutex.  Six static mutexes are
-** used by the current version of SQLite.  Future versions of SQLite
-** may add additional static mutexes.  Static mutexes are for internal
-** use by SQLite only.  Applications that use SQLite mutexes should
-** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
-** SQLITE_MUTEX_RECURSIVE.
-**
-** Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
-** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
-** returns a different mutex on every call.  But for the static 
-** mutex types, the same mutex is returned on every call that has

-** The sqlite3_mutex_alloc() routine allocates a new
-** mutex and returns a pointer to it.  If it returns NULL
-** that means that a mutex could not be allocated.  SQLite
-** will unwind its stack and return an error.  The argument
-** to sqlite3_mutex_alloc() is one of these integer constants:
-**
-** <ul>
-** <li>  SQLITE_MUTEX_FAST
-** <li>  SQLITE_MUTEX_RECURSIVE
-** <li>  SQLITE_MUTEX_STATIC_MASTER
-** <li>  SQLITE_MUTEX_STATIC_MEM
-** <li>  SQLITE_MUTEX_STATIC_OPEN
-** <li>  SQLITE_MUTEX_STATIC_PRNG
-** <li>  SQLITE_MUTEX_STATIC_LRU
-** <li>  SQLITE_MUTEX_STATIC_PMEM
-** <li>  SQLITE_MUTEX_STATIC_APP1
-** <li>  SQLITE_MUTEX_STATIC_APP2
-** <li>  SQLITE_MUTEX_STATIC_APP3
-** <li>  SQLITE_MUTEX_STATIC_VFS1
-** <li>  SQLITE_MUTEX_STATIC_VFS2
-** <li>  SQLITE_MUTEX_STATIC_VFS3
-** </ul>
-**
-** The first two constants cause sqlite3_mutex_alloc() to create
-** a new mutex.  The new mutex is recursive when SQLITE_MUTEX_RECURSIVE
-** is used but not necessarily so when SQLITE_MUTEX_FAST is used.
-** The mutex implementation does not need to make a distinction
-** between SQLITE_MUTEX_RECURSIVE and SQLITE_MUTEX_FAST if it does
-** not want to.  But SQLite will only request a recursive mutex in
-** cases where it really needs one.  If a faster non-recursive mutex
-** implementation is available on the host platform, the mutex subsystem
-** might return such a mutex in response to SQLITE_MUTEX_FAST.
-**
-** The other allowed parameters to sqlite3_mutex_alloc() each return
-** a pointer to a static preexisting mutex.  Six static mutexes are
-** used by the current version of SQLite.  Future versions of SQLite
-** may add additional static mutexes.  Static mutexes are for internal
-** use by SQLite only.  Applications that use SQLite mutexes should
-** use only the dynamic mutexes returned by SQLITE_MUTEX_FAST or
-** SQLITE_MUTEX_RECURSIVE.
-**
-** Note that if one of the dynamic mutex parameters (SQLITE_MUTEX_FAST
-** or SQLITE_MUTEX_RECURSIVE) is used then sqlite3_mutex_alloc()
-** returns a different mutex on every call.  But for the static
-** mutex types, the same mutex is returned on every call that has

-** File Locking Notes:  (Mostly about windows but also some info for Unix)
-**
-** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
-** those functions are not available.  So we use only LockFile() and
-** UnlockFile().
-**
-** LockFile() prevents not just writing but also reading by other processes.
-** A SHARED_LOCK is obtained by locking a single randomly-chosen 
-** byte out of a specific range of bytes. The lock byte is obtained at 
-** random so two separate readers can probably access the file at the 
-** same time, unless they are unlucky and choose the same lock byte.
-** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range.
-** There can only be one writer.  A RESERVED_LOCK is obtained by locking
-** a single byte of the file that is designated as the reserved lock byte.
-** A PENDING_LOCK is obtained by locking a designated byte different from
-** the RESERVED_LOCK byte.
-**
-** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available,
-** which means we can use reader/writer locks.  When reader/writer locks
-** are used, the lock is placed on the same range of bytes that is used
-** for probabilistic locking in Win95/98/ME.  Hence, the locking scheme
-** will support two or more Win95 readers or two or more WinNT readers.
-** But a single Win95 reader will lock out all WinNT readers and a single
-** WinNT reader will lock out all other Win95 readers.
-**
-** The following #defines specify the range of bytes used for locking.
-** SHARED_SIZE is the number of bytes available in the pool from which
-** a random byte is selected for a shared lock.  The pool of bytes for
-** shared locks begins at SHARED_FIRST. 
-**
-** The same locking strategy and
-** byte ranges are used for Unix.  This leaves open the possibility of having
-** clients on win95, winNT, and unix all talking to the same shared file
-** and all locking correctly.  To do so would require that samba (or whatever
-** tool is being used for file sharing) implements locks correctly between
-** windows and unix.  I'm guessing that isn't likely to happen, but by
-** using the same locking range we are at least open to the possibility.
-**
-** Locking in windows is manditory.  For this reason, we cannot store
-** actual data in the bytes used for locking.  The pager never allocates
-** the pages involved in locking therefore.  SHARED_SIZE is selected so
-** that all locks will fit on a single page even at the minimum page size.
-** PENDING_BYTE defines the beginning of the locks.  By default PENDING_BYTE

-**
-** The layout of divisions is as follows:
-**
-**   *  General-purpose declarations and utility functions.
-**   *  Unique file ID logic used by VxWorks.
-**   *  Various locking primitive implementations (all except proxy locking):
-**      + for Posix Advisory Locks
-**      + for no-op locks
-**      + for dot-file locks
-**      + for flock() locking
-**      + for named semaphore locks (VxWorks only)
-**      + for AFP filesystem locks (MacOSX only)
-**   *  sqlite3_file methods not associated with locking.

-******************************************************************************/

-/******************************************************************************
-*************************** Posix Advisory Locking ****************************
-**
-** POSIX advisory locks are broken by design.  ANSI STD 1003.1 (1996)
-** section 6.5.2.2 lines 483 through 490 specify that when a process
-** sets or clears a lock, that operation overrides any prior locks set
-** by the same process.  It does not explicitly say so, but this implies
-** that it overrides locks set by the same process using a different
-** file descriptor.  Consider this test case:
-**
-**       int fd1 = open("./file1", O_RDWR|O_CREAT, 0644);
-**       int fd2 = open("./file2", O_RDWR|O_CREAT, 0644);
-**
-** Suppose ./file1 and ./file2 are really the same file (because
-** one is a hard or symbolic link to the other) then if you set
-** an exclusive lock on fd1, then try to get an exclusive lock
-** on fd2, it works.  I would have expected the second lock to
-** fail since there was already a lock on the file due to fd1.
-** But not so.  Since both locks came from the same process, the
-** second overrides the first, even though they were on different
-** file descriptors opened on different file names.
-**
-** This means that we cannot use POSIX locks to synchronize file access
-** among competing threads of the same process.  POSIX locks will work fine
-** to synchronize access for threads in separate processes, but not
-** threads within the same process.
-**
-** To work around the problem, SQLite has to manage file locks internally
-** on its own.  Whenever a new database is opened, we have to find the
-** specific inode of the database file (the inode is determined by the
-** st_dev and st_ino fields of the stat structure that fstat() fills in)
-** and check for locks already existing on that inode.  When locks are
-** created or removed, we have to look at our own internal record of the
-** locks to see if another thread has previously set a lock on that same
-** inode.
-**
-** (Aside: The use of inode numbers as unique IDs does not work on VxWorks.
-** For VxWorks, we have to use the alternative unique ID system based on
-** canonical filename and implemented in the previous division.)
-**
-** The sqlite3_file structure for POSIX is no longer just an integer file
-** descriptor.  It is now a structure that holds the integer file
-** descriptor and a pointer to a structure that describes the internal
-** locks on the corresponding inode.  There is one locking structure
-** per inode, so if the same inode is opened twice, both unixFile structures
-** point to the same locking structure.  The locking structure keeps
-** a reference count (so we will know when to delete it) and a "cnt"
-** field that tells us its internal lock status.  cnt==0 means the
-** file is unlocked.  cnt==-1 means the file has an exclusive lock.
-** cnt>0 means there are cnt shared locks on the file.
-**
-** Any attempt to lock or unlock a file first checks the locking
-** structure.  The fcntl() system call is only invoked to set a 
-** POSIX lock if the internal lock structure transitions between
-** a locked and an unlocked state.
-**
-** But wait:  there are yet more problems with POSIX advisory locks.
-**
-** If you close a file descriptor that points to a file that has locks,
-** all locks on that file that are owned by the current process are
-** released.  To work around this problem, each unixInodeInfo object
-** maintains a count of the number of pending locks on tha inode.
-** When an attempt is made to close an unixFile, if there are
-** other unixFile open on the same inode that are holding locks, the call
-** to close() the file descriptor is deferred until all of the locks clear.
-** The unixInodeInfo structure keeps a list of file descriptors that need to
-** be closed and that list is walked (and cleared) when the last lock
-** clears.
-**
-** Yet another problem:  LinuxThreads do not play well with posix locks.
-**
-** Many older versions of linux use the LinuxThreads library which is
-** not posix compliant.  Under LinuxThreads, a lock created by thread
-** A cannot be modified or overridden by a different thread B.
-** Only thread A can modify the lock.  Locking behavior is correct
-** if the appliation uses the newer Native Posix Thread Library (NPTL)
-** on linux - with NPTL a lock created by thread A can override locks
-** in thread B.  But there is no way to know at compile-time which
-** threading library is being used.  So there is no way to know at
-** compile-time whether or not thread A can override locks on thread B.
-** One has to do a run-time check to discover the behavior of the
-** current process.
-**
-** SQLite used to support LinuxThreads.  But support for LinuxThreads
-** was dropped beginning with version 3.7.0.  SQLite will still work with
-** LinuxThreads provided that (1) there is no more than one connection 
-** per database file in the same process and (2) database connections
-** do not move across threads.

-  ** slightly in order to be compatible with Windows95 systems simultaneously
-  ** accessing the same database file, in case that is ever required.
-  **
-  ** Symbols defined in os.h indentify the 'pending byte' and the 'reserved
-  ** byte', each single bytes at well known offsets, and the 'shared byte
-  ** range', a range of 510 bytes at a well known offset.
-  **
-  ** To obtain a SHARED lock, a read-lock is obtained on the 'pending
-  ** byte'.  If this is successful, 'shared byte range' is read-locked
-  ** and the lock on the 'pending byte' released.  (Legacy note:  When
-  ** SQLite was first developed, Windows95 systems were still very common,
-  ** and Widnows95 lacks a shared-lock capability.  So on Windows95, a
-  ** single randomly selected by from the 'shared byte range' is locked.
-  ** Windows95 is now pretty much extinct, but this work-around for the
-  ** lack of shared-locks on Windows95 lives on, for backwards
-  ** compatibility.)
-  **
-  ** A process may only obtain a RESERVED lock after it has a SHARED lock.
-  ** A RESERVED lock is implemented by grabbing a write-lock on the
-  ** 'reserved byte'. 
-  **
-  ** A process may only obtain a PENDING lock after it has obtained a
-  ** SHARED lock. A PENDING lock is implemented by obtaining a write-lock
-  ** on the 'pending byte'. This ensures that no new SHARED locks can be
-  ** obtained, but existing SHARED locks are allowed to persist. A process
-  ** does not have to obtain a RESERVED lock on the way to a PENDING lock.
-  ** This property is used by the algorithm for rolling back a journal file
-  ** after a crash.
-  **
-  ** An EXCLUSIVE lock, obtained after a PENDING lock is held, is
-  ** implemented by obtaining a write-lock on the entire 'shared byte
-  ** range'. Since all other locks require a read-lock on one of the bytes
-  ** within this range, this ensures that no other locks are held on the

-**
-**    (1)  There is zero concurrency.  A single reader blocks all other
-**         connections from reading or writing the database.
-**
-**    (2)  An application crash or power loss can leave stale lock files
-**         sitting around that need to be cleared manually.
-**
-** Nevertheless, a dotlock is an appropriate locking mode for use if no
-** other locking strategy is available.
-**
-** Dotfile locking works by creating a subdirectory in the same directory as
-** the database and with the same name but with a ".lock" extension added.
-** The existence of a lock directory implies an EXCLUSIVE lock.  All other

-** Open a shared-memory area associated with open database file pDbFd.  
-** This particular implementation uses mmapped files.
-**
-** The file used to implement shared-memory is in the same directory
-** as the open database file and has the same name as the open database
-** file with the "-shm" suffix added.  For example, if the database file
-** is "/home/user1/config.db" then the file that is created and mmapped
-** for shared memory will be called "/home/user1/config.db-shm".  
-**
-** Another approach to is to use files in /dev/shm or /dev/tmp or an
-** some other tmpfs mount. But if a file in a different directory
-** from the database file is used, then differing access permissions
-** or a chroot() might cause two different processes on the same
-** database to end up using different files for shared memory - 
-** meaning that their memory would not really be shared - resulting
-** in database corruption.  Nevertheless, this tmpfs file usage
-** can be enabled at compile-time using -DSQLITE_SHM_DIRECTORY="/dev/shm"
-** or the equivalent.  The use of the SQLITE_SHM_DIRECTORY compile-time
-** option results in an incompatible build of SQLite;  builds of SQLite
-** that with differing SQLITE_SHM_DIRECTORY settings attempt to use the
-** same database file at the same time, database corruption will likely
-** result. The SQLITE_SHM_DIRECTORY compile-time option is considered
-** "unsupported" and may go away in a future SQLite release.
-**
-** When opening a new shared-memory file, if no other instances of that
-** file are currently open, in this process or in other processes, then
-** the file must be truncated to zero length or have its header cleared.
-**
-** If the original database file (pDbFd) is using the "unix-excl" VFS
-** that means that an exclusive lock is held on the database file and
-** that no other processes are able to read or write the database.  In
-** that case, we do not really need shared memory.  No shared memory
-** file is created.  The shared memory will be simulated with heap memory.

-************************** Begin Proxy Locking ********************************
-**
-** Proxy locking is a "uber-locking-method" in this sense:  It uses the
-** other locking methods on secondary lock files.  Proxy locking is a
-** meta-layer over top of the primitive locking implemented above.  For
-** this reason, the division that implements of proxy locking is deferred
-** until late in the file (here) after all of the other I/O methods have
-** been defined - so that the primitive locking methods are available
-** as services to help with the implementation of proxy locking.
-**
-****
-**
-** The default locking schemes in SQLite use byte-range locks on the
-** database file to coordinate safe, concurrent access by multiple readers
-** and writers [http://sqlite.org/lockingv3.html].  The five file locking
-** states (UNLOCKED, PENDING, SHARED, RESERVED, EXCLUSIVE) are implemented
-** as POSIX read & write locks over fixed set of locations (via fsctl),
-** on AFP and SMB only exclusive byte-range locks are available via fsctl
-** with _IOWR('z', 23, struct ByteRangeLockPB2) to track the same 5 states.
-** To simulate a F_RDLCK on the shared range, on AFP a randomly selected
-** address in the shared range is taken for a SHARED lock, the entire
-** shared range is taken for an EXCLUSIVE lock):
-**
-**      PENDING_BYTE        0x40000000
-**      RESERVED_BYTE       0x40000001
-**      SHARED_RANGE        0x40000002 -> 0x40000200
-**
-** This works well on the local file system, but shows a nearly 100x
-** slowdown in read performance on AFP because the AFP client disables
-** the read cache when byte-range locks are present.  Enabling the read
-** cache exposes a cache coherency problem that is present on all OS X
-** supported network file systems.  NFS and AFP both observe the
-** close-to-open semantics for ensuring cache coherency
-** [http://nfs.sourceforge.net/#faq_a8], which does not effectively
-** address the requirements for concurrent database access by multiple
-** readers and writers
-** [http://www.nabble.com/SQLite-on-NFS-cache-coherency-td15655701.html].
-**
-** To address the performance and cache coherency issues, proxy file locking
-** changes the way database access is controlled by limiting access to a
-** single host at a time and moving file locks off of the database file
-** and onto a proxy file on the local file system.  
-**
-**
-** Using proxy locks
-** -----------------
-**
-** C APIs
-**
-**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_SET_LOCKPROXYFILE,
-**                       <proxy_path> | ":auto:");
-**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_GET_LOCKPROXYFILE,
-**                       &<proxy_path>);
-**
-**
-** SQL pragmas
-**
-**  PRAGMA [database.]lock_proxy_file=<proxy_path> | :auto:
-**  PRAGMA [database.]lock_proxy_file
-**
-** Specifying ":auto:" means that if there is a conch file with a matching
-** host ID in it, the proxy path in the conch file will be used, otherwise
-** a proxy path based on the user's temp dir
-** (via confstr(_CS_DARWIN_USER_TEMP_DIR,...)) will be used and the
-** actual proxy file name is generated from the name and path of the
-** database file.  For example:
-**
-**       For database path "/Users/me/foo.db" 
-**       The lock path will be "<tmpdir>/sqliteplocks/_Users_me_foo.db:auto:")
-**
-** Once a lock proxy is configured for a database connection, it can not
-** be removed, however it may be switched to a different proxy path via
-** the above APIs (assuming the conch file is not being held by another
-** connection or process). 
-**
-**
-** How proxy locking works
-** -----------------------
-**
-** Proxy file locking relies primarily on two new supporting files: 
-**
-**   *  conch file to limit access to the database file to a single host
-**      at a time
-**
-**   *  proxy file to act as a proxy for the advisory locks normally
-**      taken on the database
-**
-** The conch file - to use a proxy file, sqlite must first "hold the conch"
-** by taking an sqlite-style shared lock on the conch file, reading the
-** contents and comparing the host's unique host ID (see below) and lock
-** proxy path against the values stored in the conch.  The conch file is
-** stored in the same directory as the database file and the file name
-** is patterned after the database file name as ".<databasename>-conch".
-** If the conch file does not exist, or its contents do not match the
-** host ID and/or proxy path, then the lock is escalated to an exclusive
-** lock and the conch file contents is updated with the host ID and proxy
-** path and the lock is downgraded to a shared lock again.  If the conch
-** is held by another process (with a shared lock), the exclusive lock
-** will fail and SQLITE_BUSY is returned.
-**
-** The proxy file - a single-byte file used for all advisory file locks
-** normally taken on the database file.   This allows for safe sharing
-** of the database file for multiple readers and writers on the same
-** host (the conch ensures that they all use the same local lock file).
-**
-** Requesting the lock proxy does not immediately take the conch, it is
-** only taken when the first request to lock database file is made.  
-** This matches the semantics of the traditional locking behavior, where
-** opening a connection to a database file does not take a lock on it.
-** The shared lock and an open file descriptor are maintained until 
-** the connection to the database is closed. 
-**
-** The proxy file and the lock file are never deleted so they only need
-** to be created the first time they are used.
-**
-** Configuration options
-** ---------------------
-**
-**  SQLITE_PREFER_PROXY_LOCKING
-**
-**       Database files accessed on non-local file systems are
-**       automatically configured for proxy locking, lock files are
-**       named automatically using the same logic as
-**       PRAGMA lock_proxy_file=":auto:"
-**    
-**  SQLITE_PROXY_DEBUG
-**
-**       Enables the logging of error messages during host id file
-**       retrieval and creation
-**
-**  LOCKPROXYDIR
-**
-**       Overrides the default directory used for lock proxy files that
-**       are named automatically via the ":auto:" setting
-**
-**  SQLITE_DEFAULT_PROXYDIR_PERMISSIONS
-**
-**       Permissions to use when creating a directory for storing the
-**       lock proxy files, only used when LOCKPROXYDIR is not set.
-**    
-**    
-** As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING,
-** setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will
-** force proxy locking to be used for every database file opened, and 0
-** will force automatic proxy locking to be disabled for all database
-** files (explicitly calling the SQLITE_FCNTL_SET_LOCKPROXYFILE pragma or
-** sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING).

-/******************* NOTES ON THE DESIGN OF THE PAGER ************************
-**
-** This comment block describes invariants that hold when using a rollback
-** journal.  These invariants do not apply for journal_mode=WAL,
-** journal_mode=MEMORY, or journal_mode=OFF.
-**
-** Within this comment block, a page is deemed to have been synced
-** automatically as soon as it is written when PRAGMA synchronous=OFF.
-** Otherwise, the page is not synced until the xSync method of the VFS
-** is called successfully on the file containing the page.
-**
-** Definition:  A page of the database file is said to be "overwriteable" if
-** one or more of the following are true about the page:
-** 
-**     (a)  The original content of the page as it was at the beginning of
-**          the transaction has been written into the rollback journal and
-**          synced.
-** 
-**     (b)  The page was a freelist leaf page at the start of the transaction.
-** 
-**     (c)  The page number is greater than the largest page that existed in
-**          the database file at the start of the transaction.
-** 
-** (1) A page of the database file is never overwritten unless one of the
-**     following are true:
-** 
-**     (a) The page and all other pages on the same sector are overwriteable.
-** 
-**     (b) The atomic page write optimization is enabled, and the entire
-**         transaction other than the update of the transaction sequence
-**         number consists of a single page change.
-** 
-** (2) The content of a page written into the rollback journal exactly matches
-**     both the content in the database when the rollback journal was written
-**     and the content in the database at the beginning of the current
-**     transaction.
-** 
-** (3) Writes to the database file are an integer multiple of the page size
-**     in length and are aligned on a page boundary.
-** 
-** (4) Reads from the database file are either aligned on a page boundary and
-**     an integer multiple of the page size in length or are taken from the
-**     first 100 bytes of the database file.
-** 
-** (5) All writes to the database file are synced prior to the rollback journal
-**     being deleted, truncated, or zeroed.
-** 
-** (6) If a master journal file is used, then all writes to the database file
-**     are synced prior to the master journal being deleted.
-** 
-** Definition: Two databases (or the same database at two points it time)
-** are said to be "logically equivalent" if they give the same answer to
-** all queries.  Note in particular the content of freelist leaf
-** pages can be changed arbitrarily without affecting the logical equivalence
-** of the database.
-** 
-** (7) At any time, if any subset, including the empty set and the total set,
-**     of the unsynced changes to a rollback journal are removed and the 
-**     journal is rolled back, the resulting database file will be logically
-**     equivalent to the database file at the beginning of the transaction.
-** 
-** (8) When a transaction is rolled back, the xTruncate method of the VFS
-**     is called to restore the database file to the same size it was at
-**     the beginning of the transaction.  (In some VFSes, the xTruncate
-**     method is a no-op, but that does not change the fact the SQLite will
-**     invoke it.)
-** 
-** (9) Whenever the database file is modified, at least one bit in the range
-**     of bytes from 24 through 39 inclusive will be changed prior to releasing
-**     the EXCLUSIVE lock, thus signaling other connections on the same
-**     database to flush their caches.
-**
-** (10) The pattern of bits in bytes 24 through 39 shall not repeat in less
-**      than one billion transactions.
-**
-** (11) A database file is well-formed at the beginning and at the conclusion
-**      of every transaction.
-**
-** (12) An EXCLUSIVE lock is held on the database file when writing to
-**      the database file.
-**
-** (13) A SHARED lock is held on the database file while reading any
-**      content out of the database file.

-** 
-**
-**  OPEN:
-**
-**    The pager starts up in this state. Nothing is guaranteed in this
-**    state - the file may or may not be locked and the database size is
-**    unknown. The database may not be read or written.
-**
-**    * No read or write transaction is active.
-**    * Any lock, or no lock at all, may be held on the database file.
-**    * The dbSize, dbOrigSize and dbFileSize variables may not be trusted.
-**
-**  READER:
-**
-**    In this state all the requirements for reading the database in 
-**    rollback (non-WAL) mode are met. Unless the pager is (or recently
-**    was) in exclusive-locking mode, a user-level read transaction is 
-**    open. The database size is known in this state.
-**
-**    A connection running with locking_mode=normal enters this state when
-**    it opens a read-transaction on the database and returns to state
-**    OPEN after the read-transaction is completed. However a connection
-**    running in locking_mode=exclusive (including temp databases) remains in
-**    this state even after the read-transaction is closed. The only way
-**    a locking_mode=exclusive connection can transition from READER to OPEN
-**    is via the ERROR state (see below).
-** 
-**    * A read transaction may be active (but a write-transaction cannot).
-**    * A SHARED or greater lock is held on the database file.
-**    * The dbSize variable may be trusted (even if a user-level read 
-**      transaction is not active). The dbOrigSize and dbFileSize variables
-**      may not be trusted at this point.
-**    * If the database is a WAL database, then the WAL connection is open.
-**    * Even if a read-transaction is not open, it is guaranteed that 
-**      there is no hot-journal in the file-system.
-**
-**  WRITER_LOCKED:
-**
-**    The pager moves to this state from READER when a write-transaction
-**    is first opened on the database. In WRITER_LOCKED state, all locks 
-**    required to start a write-transaction are held, but no actual 
-**    modifications to the cache or database have taken place.
-**
-**    In rollback mode, a RESERVED or (if the transaction was opened with 
-**    BEGIN EXCLUSIVE) EXCLUSIVE lock is obtained on the database file when
-**    moving to this state, but the journal file is not written to or opened 
-**    to in this state. If the transaction is committed or rolled back while 
-**    in WRITER_LOCKED state, all that is required is to unlock the database 
-**    file.
-**
-**    IN WAL mode, WalBeginWriteTransaction() is called to lock the log file.
-**    If the connection is running with locking_mode=exclusive, an attempt
-**    is made to obtain an EXCLUSIVE lock on the database file.
-**
-**    * A write transaction is active.
-**    * If the connection is open in rollback-mode, a RESERVED or greater 
-**      lock is held on the database file.
-**    * If the connection is open in WAL-mode, a WAL write transaction
-**      is open (i.e. sqlite3WalBeginWriteTransaction() has been successfully
-**      called).
-**    * The dbSize, dbOrigSize and dbFileSize variables are all valid.
-**    * The contents of the pager cache have not been modified.
-**    * The journal file may or may not be open.
-**    * Nothing (not even the first header) has been written to the journal.
-**
-**  WRITER_CACHEMOD:
-**
-**    A pager moves from WRITER_LOCKED state to this state when a page is
-**    first modified by the upper layer. In rollback mode the journal file
-**    is opened (if it is not already open) and a header written to the
-**    start of it. The database file on disk has not been modified.
-**
-**    * A write transaction is active.
-**    * A RESERVED or greater lock is held on the database file.
-**    * The journal file is open and the first header has been written 
-**      to it, but the header has not been synced to disk.
-**    * The contents of the page cache have been modified.
-**
-**  WRITER_DBMOD:
-**
-**    The pager transitions from WRITER_CACHEMOD into WRITER_DBMOD state
-**    when it modifies the contents of the database file. WAL connections
-**    never enter this state (since they do not modify the database file,
-**    just the log file).
-**
-**    * A write transaction is active.
-**    * An EXCLUSIVE or greater lock is held on the database file.
-**    * The journal file is open and the first header has been written 
-**      and synced to disk.
-**    * The contents of the page cache have been modified (and possibly
-**      written to disk).
-**
-**  WRITER_FINISHED:
-**
-**    It is not possible for a WAL connection to enter this state.
-**
-**    A rollback-mode pager changes to WRITER_FINISHED state from WRITER_DBMOD
-**    state after the entire transaction has been successfully written into the
-**    database file. In this state the transaction may be committed simply
-**    by finalizing the journal file. Once in WRITER_FINISHED state, it is 
-**    not possible to modify the database further. At this point, the upper 
-**    layer must either commit or rollback the transaction.
-**
-**    * A write transaction is active.
-**    * An EXCLUSIVE or greater lock is held on the database file.
-**    * All writing and syncing of journal and database data has finished.
-**      If no error occurred, all that remains is to finalize the journal to
-**      commit the transaction. If an error did occur, the caller will need
-**      to rollback the transaction. 
-**
-**  ERROR:
-**
-**    The ERROR state is entered when an IO or disk-full error (including
-**    SQLITE_IOERR_NOMEM) occurs at a point in the code that makes it 
-**    difficult to be sure that the in-memory pager state (cache contents, 
-**    db size etc.) are consistent with the contents of the file-system.
-**
-**    Temporary pager files may enter the ERROR state, but in-memory pagers
-**    cannot.
-**
-**    For example, if an IO error occurs while performing a rollback, 
-**    the contents of the page-cache may be left in an inconsistent state.
-**    At this point it would be dangerous to change back to READER state
-**    (as usually happens after a rollback). Any subsequent readers might
-**    report database corruption (due to the inconsistent cache), and if
-**    they upgrade to writers, they may inadvertently corrupt the database
-**    file. To avoid this hazard, the pager switches into the ERROR state
-**    instead of READER following such an error.
-**
-**    Once it has entered the ERROR state, any attempt to use the pager
-**    to read or write data returns an error. Eventually, once all 
-**    outstanding transactions have been abandoned, the pager is able to
-**    transition back to OPEN state, discarding the contents of the 
-**    page-cache and any other in-memory state at the same time. Everything
-**    is reloaded from disk (and, if necessary, hot-journal rollback peformed)
-**    when a read-transaction is next opened on the pager (transitioning
-**    the pager into READER state). At that point the system has recovered 
-**    from the error.
-**
-**    Specifically, the pager jumps into the ERROR state if:
-**
-**      1. An error occurs while attempting a rollback. This happens in
-**         function sqlite3PagerRollback().
-**
-**      2. An error occurs while attempting to finalize a journal file
-**         following a commit in function sqlite3PagerCommitPhaseTwo().
-**
-**      3. An error occurs while attempting to write to the journal or
-**         database file in function pagerStress() in order to free up
-**         memory.
-**
-**    In other cases, the error is returned to the b-tree layer. The b-tree
-**    layer then attempts a rollback operation. If the error condition 
-**    persists, the pager enters the ERROR state via condition (1) above.
-**
-**    Condition (3) is necessary because it can be triggered by a read-only
-**    statement executed within a transaction. In this case, if the error
-**    code were simply returned to the user, the b-tree layer would not
-**    automatically attempt a rollback, as it assumes that an error in a
-**    read-only statement cannot leave the pager in an internally inconsistent 
-**    state.
-**
-**    * The Pager.errCode variable is set to something other than SQLITE_OK.
-**    * There are one or more outstanding references to pages (after the
-**      last reference is dropped the pager should move back to OPEN state).
-**    * The pager is not an in-memory pager.
-**    
-**
-** Notes:
-**
-**   * A pager is never in WRITER_DBMOD or WRITER_FINISHED state if the
-**     connection is open in WAL mode. A WAL connection is always in one
-**     of the first four states.
-**
-**   * Normally, a connection open in exclusive mode is never in PAGER_OPEN
-**     state. There are two exceptions: immediately after exclusive-mode has
-**     been turned on (and before any read or write transactions are

-** The Pager.eLock variable is almost always set to one of the 
-** following locking-states, according to the lock currently held on
-** the database file: NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
-** This variable is kept up to date as locks are taken and released by
-** the pagerLockDb() and pagerUnlockDb() wrappers.
-**
-** If the VFS xLock() or xUnlock() returns an error other than SQLITE_BUSY
-** (i.e. one of the SQLITE_IOERR subtypes), it is not clear whether or not
-** the operation was successful. In these circumstances pagerLockDb() and
-** pagerUnlockDb() take a conservative approach - eLock is always updated
-** when unlocking the file, and only updated when locking the file if the
-** VFS call is successful. This way, the Pager.eLock variable may be set
-** to a less exclusive (lower) value than the lock that is actually held
-** at the system level, but it is never set to a more exclusive value.
-**
-** This is usually safe. If an xUnlock fails or appears to fail, there may 
-** be a few redundant xLock() calls or a lock may be held for longer than
-** required, but nothing really goes wrong.
-**
-** The exception is when the database file is unlocked as the pager moves
-** from ERROR to OPEN state. At this point there may be a hot-journal file 
-** in the file-system that needs to be rolled back (as part of an OPEN->SHARED
-** transition, by the same pager or any other). If the call to xUnlock()
-** fails at this point and the pager is left holding an EXCLUSIVE lock, this
-** can confuse the call to xCheckReservedLock() call made later as part
-** of hot-journal detection.
-**
-** xCheckReservedLock() is defined as returning true "if there is a RESERVED 
-** lock held by this process or any others". So xCheckReservedLock may 
-** return true because the caller itself is holding an EXCLUSIVE lock (but
-** doesn't know it because of a previous error in xUnlock). If this happens
-** a hot-journal may be mistaken for a journal being created by an active
-** transaction in another process, causing SQLite to read from the database
-** without rolling it back.
-**
-** To work around this, if a call to xUnlock() fails when unlocking the
-** database in the ERROR state, Pager.eLock is set to UNKNOWN_LOCK. It
-** is only changed back to a real locking state after a successful call
-** to xLock(EXCLUSIVE). Also, the code to do the OPEN->SHARED state transition
-** omits the check for a hot-journal if Pager.eLock is set to UNKNOWN_LOCK 
-** lock. Instead, it assumes a hot-journal exists and obtains an EXCLUSIVE
-** lock on the database file before attempting to roll it back. See function
-** PagerSharedLock() for more detail.
-**
-** Pager.eLock may only be set to UNKNOWN_LOCK when the pager is in 
-** PAGER_OPEN state.

-/*
-** An open page cache is an instance of struct Pager. A description of
-** some of the more important member variables follows:
-**
-** eState
-**
-**   The current 'state' of the pager object. See the comment and state
-**   diagram above for a description of the pager state.
-**
-** eLock
-**
-**   For a real on-disk database, the current lock held on the database file -
-**   NO_LOCK, SHARED_LOCK, RESERVED_LOCK or EXCLUSIVE_LOCK.
-**
-**   For a temporary or in-memory database (neither of which require any
-**   locks), this variable is always set to EXCLUSIVE_LOCK. Since such
-**   databases always have Pager.exclusiveMode==1, this tricks the pager
-**   logic into thinking that it already has all the locks it will ever
-**   need (and no reason to release them).
-**
-**   In some (obscure) circumstances, this variable may also be set to
-**   UNKNOWN_LOCK. See the comment above the #define of UNKNOWN_LOCK for
-**   details.
-**
-** changeCountDone
-**
-**   This boolean variable is used to make sure that the change-counter 
-**   (the 4-byte header field at byte offset 24 of the database file) is 
-**   not updated more often than necessary. 
-**
-**   It is set to true when the change-counter field is updated, which 
-**   can only happen if an exclusive lock is held on the database file.
-**   It is cleared (set to false) whenever an exclusive lock is 
-**   relinquished on the database file. Each time a transaction is committed,
-**   The changeCountDone flag is inspected. If it is true, the work of
-**   updating the change-counter is omitted for the current transaction.
-**
-**   This mechanism means that when running in exclusive mode, a connection 
-**   need only update the change-counter once, for the first transaction
-**   committed.
-**
-** setMaster
-**
-**   When PagerCommitPhaseOne() is called to commit a transaction, it may
-**   (or may not) specify a master-journal name to be written into the 
-**   journal file before it is synced to disk.
-**
-**   Whether or not a journal file contains a master-journal pointer affects 
-**   the way in which the journal file is finalized after the transaction is 
-**   committed or rolled back when running in "journal_mode=PERSIST" mode.
-**   If a journal file does not contain a master-journal pointer, it is
-**   finalized by overwriting the first journal header with zeroes. If
-**   it does contain a master-journal pointer the journal file is finalized 
-**   by truncating it to zero bytes, just as if the connection were 
-**   running in "journal_mode=truncate" mode.
-**
-**   Journal files that contain master journal pointers cannot be finalized
-**   simply by overwriting the first journal-header with zeroes, as the
-**   master journal pointer could interfere with hot-journal rollback of any
-**   subsequently interrupted transaction that reuses the journal file.
-**
-**   The flag is cleared as soon as the journal file is finalized (either
-**   by PagerCommitPhaseTwo or PagerRollback). If an IO error prevents the
-**   journal file from being successfully finalized, the setMaster flag
-**   is cleared anyway (and the pager will move to ERROR state).
-**
-** doNotSpill
-**
-**   This variables control the behavior of cache-spills  (calls made by
-**   the pcache module to the pagerStress() routine to write cached data
-**   to the file-system in order to free up memory).
-**
-**   When bits SPILLFLAG_OFF or SPILLFLAG_ROLLBACK of doNotSpill are set,
-**   writing to the database from pagerStress() is disabled altogether.
-**   The SPILLFLAG_ROLLBACK case is done in a very obscure case that
-**   comes up during savepoint rollback that requires the pcache module
-**   to allocate a new page to prevent the journal file from being written
-**   while it is being traversed by code in pager_playback().  The SPILLFLAG_OFF
-**   case is a user preference.
-** 
-**   If the SPILLFLAG_NOSYNC bit is set, writing to the database from
-**   pagerStress() is permitted, but syncing the journal file is not.
-**   This flag is set by sqlite3PagerWrite() when the file-system sector-size
-**   is larger than the database page-size in order to prevent a journal sync
-**   from happening in between the journalling of two pages on the same sector. 
-**
-** subjInMemory
-**
-**   This is a boolean variable. If true, then any required sub-journal
-**   is opened as an in-memory journal file. If false, then in-memory
-**   sub-journals are only used for in-memory pager files.
-**
-**   This variable is updated by the upper layer each time a new 
-**   write-transaction is opened.
-**
-** dbSize, dbOrigSize, dbFileSize
-**
-**   Variable dbSize is set to the number of pages in the database file.
-**   It is valid in PAGER_READER and higher states (all states except for
-**   OPEN and ERROR). 
-**
-**   dbSize is set based on the size of the database file, which may be 
-**   larger than the size of the database (the value stored at offset
-**   28 of the database header by the btree). If the size of the file
-**   is not an integer multiple of the page-size, the value stored in
-**   dbSize is rounded down (i.e. a 5KB file with 2K page-size has dbSize==2).
-**   Except, any file that is greater than 0 bytes in size is considered
-**   to have at least one page. (i.e. a 1KB file with 2K page-size leads
-**   to dbSize==1).
-**
-**   During a write-transaction, if pages with page-numbers greater than
-**   dbSize are modified in the cache, dbSize is updated accordingly.
-**   Similarly, if the database is truncated using PagerTruncateImage(), 
-**   dbSize is updated.
-**
-**   Variables dbOrigSize and dbFileSize are valid in states 
-**   PAGER_WRITER_LOCKED and higher. dbOrigSize is a copy of the dbSize
-**   variable at the start of the transaction. It is used during rollback,
-**   and to determine whether or not pages need to be journalled before
-**   being modified.
-**
-**   Throughout a write-transaction, dbFileSize contains the size of
-**   the file on disk in pages. It is set to a copy of dbSize when the
-**   write-transaction is first opened, and updated when VFS calls are made
-**   to write or truncate the database file on disk. 
-**
-**   The only reason the dbFileSize variable is required is to suppress 
-**   unnecessary calls to xTruncate() after committing a transaction. If, 
-**   when a transaction is committed, the dbFileSize variable indicates 
-**   that the database file is larger than the database image (Pager.dbSize), 
-**   pager_truncate() is called. The pager_truncate() call uses xFilesize()
-**   to measure the database file on disk, and then truncates it if required.
-**   dbFileSize is not used when rolling back a transaction. In this case
-**   pager_truncate() is called unconditionally (which means there may be
-**   a call to xFilesize() that is not strictly required). In either case,
-**   pager_truncate() may cause the file to become smaller or larger.
-**
-** dbHintSize
-**
-**   The dbHintSize variable is used to limit the number of calls made to
-**   the VFS xFileControl(FCNTL_SIZE_HINT) method. 
-**
-**   dbHintSize is set to a copy of the dbSize variable when a
-**   write-transaction is opened (at the same time as dbFileSize and
-**   dbOrigSize). If the xFileControl(FCNTL_SIZE_HINT) method is called,
-**   dbHintSize is increased to the number of pages that correspond to the
-**   size-hint passed to the method call. See pager_write_pagelist() for 
-**   details.
-**
-** errCode
-**
-**   The Pager.errCode variable is only ever used in PAGER_ERROR state. It
-**   is set to zero in all other states. In PAGER_ERROR state, Pager.errCode 
-**   is always set to SQLITE_FULL, SQLITE_IOERR or one of the SQLITE_IOERR_XXX 
-**   sub-codes.
-**
-** syncFlags, walSyncFlags
-**
-**   syncFlags is either SQLITE_SYNC_NORMAL (0x02) or SQLITE_SYNC_FULL (0x03).
-**   syncFlags is used for rollback mode.  walSyncFlags is used for WAL mode
-**   and contains the flags used to sync the checkpoint operations in the
-**   lower two bits, and sync flags used for transaction commits in the WAL
-**   file in bits 0x04 and 0x08.  In other words, to get the correct sync flags
-**   for checkpoint operations, use (walSyncFlags&0x03) and to get the correct
-**   sync flags for transaction commit, use ((walSyncFlags>>2)&0x03).  Note
-**   that with synchronous=NORMAL in WAL mode, transaction commit is not synced
-**   meaning that the 0x04 and 0x08 bits are both zero.

-** This routine ends a transaction. A transaction is usually ended by 
-** either a COMMIT or a ROLLBACK operation. This routine may be called 
-** after rollback of a hot-journal, or if an error occurs while opening
-** the journal file or writing the very first journal-header of a
-** database transaction.
-** 
-** This routine is never called in PAGER_ERROR state. If it is called
-** in PAGER_NONE or PAGER_SHARED state and the lock held is less
-** exclusive than a RESERVED lock, it is a no-op.
-**
-** Otherwise, any active savepoints are released.
-**
-** If the journal file is open, then it is "finalized". Once a journal 
-** file has been finalized it is not possible to use it to roll back a 
-** transaction. Nor will it be considered to be a hot-journal by this
-** or any other database connection. Exactly how a journal is finalized
-** depends on whether or not the pager is running in exclusive mode and
-** the current journal-mode (Pager.journalMode value), as follows:
-**
-**   journalMode==MEMORY
-**     Journal file descriptor is simply closed. This destroys an 
-**     in-memory journal.
-**
-**   journalMode==TRUNCATE
-**     Journal file is truncated to zero bytes in size.
-**
-**   journalMode==PERSIST
-**     The first 28 bytes of the journal file are zeroed. This invalidates
-**     the first journal header in the file, and hence the entire journal
-**     file. An invalid journal file cannot be rolled back.
-**
-**   journalMode==DELETE
-**     The journal file is closed and deleted using sqlite3OsDelete().
-**
-**     If the pager is running in exclusive mode, this method of finalizing
-**     the journal file is never used. Instead, if the journalMode is
-**     DELETE and the pager is in exclusive mode, the method described under
-**     journalMode==PERSIST is used instead.
-**
-** After the journal is finalized, the pager moves to PAGER_READER state.
-** If running in non-exclusive rollback mode, the lock on the file is 
-** downgraded to a SHARED_LOCK.
-**
-** SQLITE_OK is returned if no error occurs. If an error occurs during
-** any of the IO operations to finalize the journal file or unlock the
-** database then the IO error code is returned to the user. If the 
-** operation to finalize the journal file fails, then the code still
-** tries to unlock the database file if not in exclusive mode. If the
-** unlock operation fails as well, then the first error code related
-** to the first error encountered (the journal finalization one) is
-** returned.

-**
-** The journal file format is as follows: 
-**
-**  (1)  8 byte prefix.  A copy of aJournalMagic[].
-**  (2)  4 byte big-endian integer which is the number of valid page records
-**       in the journal.  If this value is 0xffffffff, then compute the
-**       number of page records from the journal size.
-**  (3)  4 byte big-endian integer which is the initial value for the 
-**       sanity checksum.
-**  (4)  4 byte integer which is the number of pages to truncate the
-**       database to during a rollback.
-**  (5)  4 byte big-endian integer which is the sector size.  The header
-**       is this many bytes in size.
-**  (6)  4 byte big-endian integer which is the page size.
-**  (7)  zero padding out to the next sector size.
-**  (8)  Zero or more pages instances, each as follows:
-**        +  4 byte page number.
-**        +  pPager->pageSize bytes of data.
-**        +  4 byte checksum
-**
-** When we speak of the journal header, we mean the first 7 items above.
-** Each entry in the journal is an instance of the 8th item.
-**
-** Call the value from the second bullet "nRec".  nRec is the number of
-** valid page entries in the journal.  In most cases, you can compute the
-** value of nRec from the size of the journal file.  But if a power
-** failure occurred while the journal was being written, it could be the
-** case that the size of the journal file had already been increased but
-** the extra entries had not yet made it safely to disk.  In such a case,
-** the value of nRec computed from the file size would be too large.  For
-** that reason, we always use the nRec value in the header.
-**
-** If the nRec value is 0xffffffff it means that nRec should be computed
-** from the file size.  This value is used when the user selects the
-** no-sync option for the journal.  A power failure could lead to corruption
-** in this case.  But for things like temporary table (which will be
-** deleted when the power is restored) we don't care.  
-**
-** If the file opened as the journal file is not a well-formed
-** journal file then all pages up to the first corrupted page are rolled
-** back (or no pages if the journal header is corrupted). The journal file
-** is then deleted and SQLITE_OK returned, just as if no corruption had

-**
-** The "level" in pgFlags & PAGER_SYNCHRONOUS_MASK sets the robustness
-** of the database to damage due to OS crashes or power failures by
-** changing the number of syncs()s when writing the journals.
-** There are four levels:
-**
-**    OFF       sqlite3OsSync() is never called.  This is the default
-**              for temporary and transient files.
-**
-**    NORMAL    The journal is synced once before writes begin on the
-**              database.  This is normally adequate protection, but
-**              it is theoretically possible, though very unlikely,
-**              that an inopertune power failure could leave the journal
-**              in a state which would cause damage to the database
-**              when it is rolled back.
-**
-**    FULL      The journal is synced twice before writes begin on the
-**              database (with some additional information - the nRec field
-**              of the journal header - being written in between the two
-**              syncs).  If we assume that writing a
-**              single disk sector is atomic, then this mode provides
-**              assurance that the journal will not be corrupted to the
-**              point of causing damage to the database during rollback.
-**
-**    EXTRA     This is like FULL except that is also syncs the directory
-**              that contains the rollback journal after the rollback
-**              journal is unlinked.
-**
-** The above is for a rollback-journal mode.  For WAL mode, OFF continues
-** to mean that no syncs ever occur.  NORMAL means that the WAL is synced
-** prior to the start of checkpoint and that the database file is synced
-** at the conclusion of the checkpoint if the entire content of the WAL
-** was written back into the database.  But no sync operations occur for
-** an ordinary commit in NORMAL mode with WAL.  FULL means that the WAL
-** file is synced following each commit operation, in addition to the
-** syncs associated with NORMAL.  There is no difference between FULL
-** and EXTRA for WAL mode.
-**
-** Do not confuse synchronous=FULL with SQLITE_SYNC_FULL.  The
-** SQLITE_SYNC_FULL macro means to use the MacOSX-style full-fsync
-** using fcntl(F_FULLFSYNC).  SQLITE_SYNC_NORMAL means to do an
-** ordinary fsync() call.  There is no difference between SQLITE_SYNC_FULL
-** and SQLITE_SYNC_NORMAL on platforms other than MacOSX.  But the
-** synchronous=FULL versus synchronous=NORMAL setting determines when
-** the xSync primitive is called and is relevant to all platforms.
-**
-** Numeric values associated with these states are OFF==1, NORMAL=2,
-** and FULL=3.

-**     getPageNormal()         --  The normal getter
-**     getPageError()          --  Used if the pager is in an error state
-**     getPageMmap()           --  Used if memory-mapped I/O is enabled
-**
-** If the requested page is already in the cache, it is returned. 
-** Otherwise, a new page object is allocated and populated with data
-** read from the database file. In some cases, the pcache module may
-** choose not to allocate a new page object and may reuse an existing
-** object with no outstanding references.
-**
-** The extra data appended to a page is always initialized to zeros the 
-** first time a page is loaded into memory. If the page requested is 
-** already in the cache when this function is called, then the extra
-** data is left as it was when the page object was last used.
-**
-** If the database image is smaller than the requested page or if 
-** the flags parameter contains the PAGER_GET_NOCONTENT bit and the 
-** requested page is not already stored in the cache, then no 
-** actual disk read occurs. In this case the memory image of the 
-** page is initialized to all zeros. 
-**
-** If PAGER_GET_NOCONTENT is true, it means that we do not care about
-** the contents of the page. This occurs in two scenarios:
-**
-**   a) When reading a free-list leaf page from the database, and
-**
-**   b) When a savepoint is being rolled back and we need to load
-**      a new page into the cache to be filled with the data read
-**      from the savepoint journal.
-**
-** If PAGER_GET_NOCONTENT is true, then the data returned is zeroed instead
-** of being read from the database. Additionally, the bits corresponding
-** to pgno in Pager.pInJournal (bitvec of pages already written to the
-** journal file) and the PagerSavepoint.pInSavepoint bitvecs of any open
-** savepoints are set. This means if the page is made writable at any
-** point in the future, using a call to sqlite3PagerWrite(), its contents
-** will not be journaled. This saves IO.
-**
-** The acquisition might fail for several reasons.  In all cases,
-** an appropriate error code is returned and *ppPage is set to NULL.
-**
-** See also sqlite3PagerLookup().  Both this routine and Lookup() attempt
-** to find a page in the in-memory cache first.  If the page is not already
-** in memory, this routine goes to disk to read it in whereas Lookup()
-** just returns 0.  This routine acquires a read-lock the first time it
-** has to go to disk, and could also playback an old journal if necessary.
-** Since Lookup() never goes to disk, it never has to deal with locks
-** or journal files.

-/*
-** A complete page cache is an instance of this structure.  Every
-** entry in the cache holds a single page of the database file.  The
-** btree layer only operates on the cached copy of the database pages.
-**
-** A page cache entry is "clean" if it exactly matches what is currently
-** on disk.  A page is "dirty" if it has been modified and needs to be
-** persisted to disk.
-**
-** pDirty, pDirtyTail, pSynced:
-**   All dirty pages are linked into the doubly linked list using
-**   PgHdr.pDirtyNext and pDirtyPrev. The list is maintained in LRU order
-**   such that p was added to the list more recently than p->pDirtyNext.
-**   PCache.pDirty points to the first (newest) element in the list and
-**   pDirtyTail to the last (oldest).
-**
-**   The PCache.pSynced variable is used to optimize searching for a dirty
-**   page to eject from the cache mid-transaction. It is better to eject
-**   a page that does not require a journal sync than one that does. 
-**   Therefore, pSynced is maintained to that it *almost* always points
-**   to either the oldest page in the pDirty/pDirtyTail list that has a
-**   clear PGHDR_NEED_SYNC flag or to a page that is older than this one
-**   (so that the right page to eject can be found by following pDirtyPrev
-**   pointers).

-*************************************************************************
-**
-** This file implements the default page cache implementation (the
-** sqlite3_pcache interface). It also contains part of the implementation
-** of the SQLITE_CONFIG_PAGECACHE and sqlite3_release_memory() features.
-** If the default page cache implementation is overridden, then neither of
-** these two features are available.
-**
-** A Page cache line looks like this:
-**
-**  -------------------------------------------------------------
-**  |  database page content   |  PgHdr1  |  MemPage  |  PgHdr  |
-**  -------------------------------------------------------------
-**
-** The database page content is up front (so that buffer overreads tend to
-** flow harmlessly into the PgHdr1, MemPage, and PgHdr extensions).   MemPage
-** is the extension added by the btree.c module containing information such
-** as the database page number and how that database page is used.  PgHdr
-** is added by the pcache.c layer and contains information used to keep track
-** of which pages are "dirty".  PgHdr1 is an extension added by this
-** module (pcache1.c).  The PgHdr1 header is a subclass of sqlite3_pcache_page.
-** PgHdr1 contains information needed to look up a page by its page number.
-** The superclass sqlite3_pcache_page.pBuf points to the start of the
-** database page content and sqlite3_pcache_page.pExtra points to PgHdr.
-**
-** The size of the extension (MemPage+PgHdr+PgHdr1) can be determined at
-** runtime using sqlite3_config(SQLITE_CONFIG_PCACHE_HDRSZ, &size).  The
-** sizes of the extensions sum to 272 bytes on x64 for 3.8.10, but this
-** size can vary according to architecture, compile-time options, and
-** SQLite library version number.
-**
-** If SQLITE_PCACHE_SEPARATE_HEADER is defined, then the extension is obtained
-** using a separate memory allocation from the database page content.  This
-** seeks to overcome the "clownshoe" problem (also called "internal
-** fragmentation" in academic literature) of allocating a few bytes more
-** than a power of two with the memory allocator rounding up to the next
-** power of two, and leaving the rounded-up space unused.
-**
-** This module tracks pointers to PgHdr1 objects.  Only pcache.c communicates
-** with this module.  Information is passed back and forth as PgHdr1 pointers.
-**
-** The pcache.c and pager.c modules deal pointers to PgHdr objects.
-** The btree.c module deals with pointers to MemPage objects.
-**
-** SOURCE OF PAGE CACHE MEMORY:
-**
-** Memory for a page might come from any of three sources:
-**
-**    (1)  The general-purpose memory allocator - sqlite3Malloc()
-**    (2)  Global page-cache memory provided using sqlite3_config() with
-**         SQLITE_CONFIG_PAGECACHE.
-**    (3)  PCache-local bulk allocation.
-**
-** The third case is a chunk of heap memory (defaulting to 100 pages worth)
-** that is allocated when the page cache is created.  The size of the local
-** bulk allocation can be adjusted using 
-**
-**     sqlite3_config(SQLITE_CONFIG_PAGECACHE, (void*)0, 0, N).
-**
-** If N is positive, then N pages worth of memory are allocated using a single
-** sqlite3Malloc() call and that memory is used for the first N pages allocated.
-** Or if N is negative, then -1024*N bytes of memory are allocated and used
-** for as many pages as can be accomodated.
-**
-** Only one of (2) or (3) can be used.  Once the memory available to (2) or
-** (3) is exhausted, subsequent allocations fail over to the general-purpose
-** memory allocator (1).
-**
-** Earlier versions of SQLite used only methods (1) and (2).  But experiments
-** show that method (3) with N==100 provides about a 5% performance boost for
-** common workloads.

-** page.  1 means allocate a new page if space is easily available.  2 
-** means to try really hard to allocate a new page.
-**
-** For a non-purgeable cache (a cache used as the storage for an in-memory

-**
-**   1. Regardless of the value of createFlag, the cache is searched for a 
-**      copy of the requested page. If one is found, it is returned.
-**
-**   2. If createFlag==0 and the page is not already in the cache, NULL is
-**      returned.

-** This routine walks an expression tree and resolves references to

-** checking on function usage and set a flag if any aggregate functions
-** are seen.
-**
-** To resolve table columns references we look for nodes (or subtrees) of the 
-** form X.Y.Z or Y.Z or just Z where
-**
-**      X:   The name of a database.  Ex:  "main" or "temp" or
-**           the symbolic name assigned to an ATTACH-ed database.
-**
-**      Y:   The name of a table in a FROM clause.  Or in a trigger
-**           one of the special names "old" or "new".
-**
-**      Z:   The name of a column in table Y.
-**
-** The node at the root of the subtree is modified as follows:
-**
-**    Expr.op        Changed to TK_COLUMN
-**    Expr.pTab      Points to the Table object for X.Y
-**    Expr.iColumn   The column index in X.Y.  -1 for the rowid.
-**    Expr.iTable    The VDBE cursor number for X.Y
-**
-**
-** To resolve result-set references, look for expression nodes of the
-** form Z (with no X and Y prefix) where the Z matches the right-hand
-** size of an AS clause in the result-set of a SELECT.  The Z expression
-** is replaced by a copy of the left-hand side of the result-set expression.
-** Table-name and function resolution occurs on the substituted expression
-** tree.  For example, in:
-**
-**      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY x;
-**
-** The "x" term of the order by is replaced by "a+b" to render:
-**
-**      SELECT a+b AS x, c+d AS y FROM t1 ORDER BY a+b;
-**
-** Function calls are checked to make sure that the function is 
-** defined and that the correct number of arguments are specified.
-** If the function is an aggregate function, then the NC_HasAgg flag is
-** set and the opcode is changed from TK_FUNCTION to TK_AGG_FUNCTION.
-** If an expression contains aggregate functions then the EP_Agg
-** property on the expression is set.
-**
-** An error message is left in pParse if anything is amiss.  The number
-** if errors is returned.

-*************************************************************************
-**
-** This module implements an object we call a "RowSet".
-**
-** The RowSet object is a collection of rowids.  Rowids
-** are inserted into the RowSet in an arbitrary order.  Inserts
-** can be intermixed with tests to see if a given rowid has been
-** previously inserted into the RowSet.
-**
-** After all inserts are finished, it is possible to extract the
-** elements of the RowSet in sorted order.  Once this extraction
-** process has started, no new elements may be inserted.
-**
-** Hence, the primitive operations for a RowSet are:
-**
-**    CREATE
-**    INSERT
-**    TEST
-**    SMALLEST
-**    DESTROY
-**
-** The CREATE and DESTROY primitives are the constructor and destructor,
-** obviously.  The INSERT primitive adds a new element to the RowSet.
-** TEST checks to see if an element is already in the RowSet.  SMALLEST
-** extracts the least value from the RowSet.
-**
-** The INSERT primitive might allocate additional memory.  Memory is
-** allocated in chunks so most INSERTs do no allocation.  There is an 
-** upper bound on the size of allocated memory.  No memory is freed
-** until DESTROY.
-**
-** The TEST primitive includes a "batch" number.  The TEST primitive
-** will only see elements that were inserted before the last change
-** in the batch number.  In other words, if an INSERT occurs between
-** two TESTs where the TESTs have the same batch nubmer, then the
-** value added by the INSERT will not be visible to the second TEST.
-** The initial batch number is zero, so if the very first TEST contains
-** a non-zero batch number, it will see all prior INSERTs.
-**
-** No INSERTs may occurs after a SMALLEST.  An assertion will fail if
-** that is attempted.
-**
-** The cost of an INSERT is roughly constant.  (Sometimes new memory
-** has to be allocated on an INSERT.)  The cost of a TEST with a new
-** batch number is O(NlogN) where N is the number of elements in the RowSet.
-** The cost of a TEST using the same batch number is O(logN).  The cost
-** of the first SMALLEST is O(NlogN).  Second and subsequent SMALLEST
-** primitives are constant time.  The cost of DESTROY is O(N).
-**
-** TEST and SMALLEST may not be used by the same RowSet.  This used to
-** be possible, but the feature was not used, so it was removed in order
-** to simplify the code.

-**    EofB:    Called when data is exhausted from selectB.
-**
-** The implementation of the latter five subroutines depend on which 
-** <operator> is used:
-**
-**
-**             UNION ALL         UNION            EXCEPT          INTERSECT
-**          -------------  -----------------  --------------  -----------------
-**   AltB:   outA, nextA      outA, nextA       outA, nextA         nextA
-**
-**   AeqB:   outA, nextA         nextA             nextA         outA, nextA
-**
-**   AgtB:   outB, nextB      outB, nextB          nextB            nextB
-**
-**   EofA:   outB, nextB      outB, nextB          halt             halt
-**
-**   EofB:   outA, nextA      outA, nextA       outA, nextA         halt
-**
-** In the AltB, AeqB, and AgtB subroutines, an EOF on A following nextA
-** causes an immediate jump to EofA and an EOF on B following nextB causes
-** an immediate jump to EofB.  Within EofA and EofB, and EOF on entry or
-** following nextX causes a jump to the end of the select processing.
-**
-** Duplicate removal in the UNION, EXCEPT, and INTERSECT cases is handled
-** within the output subroutine.  The regPrev register set holds the previously
-** output value.  A comparison is made against this value and the output
-** is skipped if the next results would be the same as the previous.
-**
-** The implementation plan is to implement the two coroutines and seven
-** subroutines first, then put the control logic at the bottom.  Like this:
-**
-**          goto Init
-**     coA: coroutine for left query (A)
-**     coB: coroutine for right query (B)
-**    outA: output one row of A
-**    outB: output one row of B (UNION and UNION ALL only)
-**    EofA: ...
-**    EofB: ...
-**    AltB: ...
-**    AeqB: ...
-**    AgtB: ...
-**    Init: initialize coroutine registers
-**          yield coA
-**          if eof(A) goto EofA
-**          yield coB
-**          if eof(B) goto EofB
-**    Cmpr: Compare A, B
-**          Jump AltB, AeqB, AgtB
-**     End: ...
-**
-** We call AltB, AeqB, AgtB, EofA, and EofB "subroutines" but they are not
-** actually called using Gosub and they do not Return.  EofA and EofB loop
-** until all data is exhausted then jump to the "end" labe.  AltB, AeqB,
-** and AgtB jump to either L2 or to one of EofA or EofB.

-** This routine attempts to flatten subqueries as a performance optimization.
-** This routine returns 1 if it makes changes and 0 if no flattening occurs.
-**
-** To understand the concept of flattening, consider the following
-** query:
-**
-**     SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
-**
-** The default way of implementing this query is to execute the
-** subquery first and store the results in a temporary table, then
-** run the outer query on that temporary table.  This requires two
-** passes over the data.  Furthermore, because the temporary table
-** has no indices, the WHERE clause on the outer query cannot be
-** optimized.
-**
-** This routine attempts to rewrite queries such as the above into
-** a single flat select, like this:
-**
-**     SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
-**
-** The code generated for this simplification gives the same result
-** but only has to scan the data once.  And because indices might 
-** exist on the table t1, a complete scan of the data might be
-** avoided.
-**
-** Flattening is subject to the following constraints:
-**
-**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
-**        The subquery and the outer query cannot both be aggregates.
-**
-**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
-**        (2) If the subquery is an aggregate then
-**        (2a) the outer query must not be a join and
-**        (2b) the outer query must not use subqueries
-**             other than the one FROM-clause subquery that is a candidate
-**             for flattening.  (This is due to ticket [2f7170d73bf9abf80]
-**             from 2015-02-09.)
-**
-**   (3)  If the subquery is the right operand of a LEFT JOIN then
-**        (3a) the subquery may not be a join and
-**        (3b) the FROM clause of the subquery may not contain a virtual
-**             table and
-**        (3c) the outer query may not be an aggregate.
-**
-**   (4)  The subquery can not be DISTINCT.
-**
-**  (**)  At one point restrictions (4) and (5) defined a subset of DISTINCT
-**        sub-queries that were excluded from this optimization. Restriction 
-**        (4) has since been expanded to exclude all DISTINCT subqueries.
-**
-**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
-**        If the subquery is aggregate, the outer query may not be DISTINCT.
-**
-**   (7)  The subquery must have a FROM clause.  TODO:  For subqueries without
-**        A FROM clause, consider adding a FROM clause with the special
-**        table sqlite_once that consists of a single row containing a
-**        single NULL.
-**
-**   (8)  If the subquery uses LIMIT then the outer query may not be a join.
-**
-**   (9)  If the subquery uses LIMIT then the outer query may not be aggregate.
-**
-**  (**)  Restriction (10) was removed from the code on 2005-02-05 but we
-**        accidently carried the comment forward until 2014-09-15.  Original
-**        constraint: "If the subquery is aggregate then the outer query 
-**        may not use LIMIT."
-**
-**  (11)  The subquery and the outer query may not both have ORDER BY clauses.
-**
-**  (**)  Not implemented.  Subsumed into restriction (3).  Was previously
-**        a separate restriction deriving from ticket #350.
-**
-**  (13)  The subquery and outer query may not both use LIMIT.
-**
-**  (14)  The subquery may not use OFFSET.
-**
-**  (15)  If the outer query is part of a compound select, then the
-**        subquery may not use LIMIT.
-**        (See ticket #2339 and ticket [02a8e81d44]).
-**
-**  (16)  If the outer query is aggregate, then the subquery may not
-**        use ORDER BY.  (Ticket #2942)  This used to not matter
-**        until we introduced the group_concat() function.  
-**
-**  (17)  If the subquery is a compound select, then
-**        (17a) all compound operators must be a UNION ALL, and
-**        (17b) no terms within the subquery compound may be aggregate
-**              or DISTINCT, and
-**        (17c) every term within the subquery compound must have a FROM clause
-**        (17d) the outer query may not be
-**              (17d1) aggregate, or
-**              (17d2) DISTINCT, or
-**              (17d3) a join.
-**
-**        The parent and sub-query may contain WHERE clauses. Subject to
-**        rules (11), (13) and (14), they may also contain ORDER BY,
-**        LIMIT and OFFSET clauses.  The subquery cannot use any compound
-**        operator other than UNION ALL because all the other compound
-**        operators have an implied DISTINCT which is disallowed by
-**        restriction (4).
-**
-**        Also, each component of the sub-query must return the same number
-**        of result columns. This is actually a requirement for any compound
-**        SELECT statement, but all the code here does is make sure that no
-**        such (illegal) sub-query is flattened. The caller will detect the
-**        syntax error and return a detailed message.
-**
-**  (18)  If the sub-query is a compound select, then all terms of the
-**        ORDER BY clause of the parent must be simple references to 
-**        columns of the sub-query.
-**
-**  (19)  If the subquery uses LIMIT then the outer query may not
-**        have a WHERE clause.
-**
-**  (20)  If the sub-query is a compound select, then it must not use
-**        an ORDER BY clause.  Ticket #3773.  We could relax this constraint
-**        somewhat by saying that the terms of the ORDER BY clause must
-**        appear as unmodified result columns in the outer query.  But we
-**        have other optimizations in mind to deal with that case.
-**
-**  (21)  If the subquery uses LIMIT then the outer query may not be
-**        DISTINCT.  (See ticket [752e1646fc]).
-**
-**  (22)  The subquery may not be a recursive CTE.
-**
-**  (**)  Subsumed into restriction (17d3).  Was: If the outer query is
-**        a recursive CTE, then the sub-query may not be a compound query.
-**        This restriction is because transforming the
-**        parent to a compound query confuses the code that handles
-**        recursive queries in multiSelect().
-**
-**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
-**        The subquery may not be an aggregate that uses the built-in min() or 
-**        or max() functions.  (Without this restriction, a query like:
-**        "SELECT x FROM (SELECT max(y), x FROM t1)" would not necessarily
-**        return the value X for which Y was maximal.)
-**
-**
-** In this routine, the "p" parameter is a pointer to the outer query.
-** The subquery is p->pSrc->a[iFrom].  isAgg is true if the outer query
-** uses aggregates.
-**
-** If flattening is not attempted, this routine is a no-op and returns 0.
-** If flattening is attempted this routine returns 1.
-**
-** All of the expression analysis must occur on both the outer query and
-** the subquery before this routine runs.

-**
-** ^The sqlite3_close() and sqlite3_close_v2() routines are destructors
-** for the [sqlite3] object.
-** ^Calls to sqlite3_close() and sqlite3_close_v2() return [SQLITE_OK] if
-** the [sqlite3] object is successfully destroyed and all associated
-** resources are deallocated.
-**
-** ^If the database connection is associated with unfinalized prepared
-** statements or unfinished sqlite3_backup objects then sqlite3_close()
-** will leave the database connection open and return [SQLITE_BUSY].
-** ^If sqlite3_close_v2() is called with unfinalized prepared statements
-** and/or unfinished sqlite3_backups, then the database connection becomes
-** an unusable "zombie" which will automatically be deallocated when the
-** last prepared statement is finalized or the last sqlite3_backup is
-** finished.  The sqlite3_close_v2() interface is intended for use with
-** host languages that are garbage collected, and where the order in which
-** destructors are called is arbitrary.
-**
-** Applications should [sqlite3_finalize | finalize] all [prepared statements],
-** [sqlite3_blob_close | close] all [BLOB handles], and 
-** [sqlite3_backup_finish | finish] all [sqlite3_backup] objects associated
-** with the [sqlite3] object prior to attempting to close the object.  ^If
-** sqlite3_close_v2() is called on a [database connection] that still has
-** outstanding [prepared statements], [BLOB handles], and/or
-** [sqlite3_backup] objects then it returns [SQLITE_OK] and the deallocation
-** of resources is deferred until all [prepared statements], [BLOB handles],
-** and [sqlite3_backup] objects are also destroyed.
-**
-** ^If an [sqlite3] object is destroyed while a transaction is open,
-** the transaction is automatically rolled back.
-**
-** The C parameter to [sqlite3_close(C)] and [sqlite3_close_v2(C)]
-** must be either a NULL
-** pointer or an [sqlite3] object pointer obtained
-** from [sqlite3_open()], [sqlite3_open16()], or
-** [sqlite3_open_v2()], and not previously closed.

-** METHOD: sqlite3
-**
-** The sqlite3_exec() interface is a convenience wrapper around
-** [sqlite3_prepare_v2()], [sqlite3_step()], and [sqlite3_finalize()],
-** that allows an application to run multiple statements of SQL
-** without having to use a lot of C code. 
-**
-** ^The sqlite3_exec() interface runs zero or more UTF-8 encoded,
-** semicolon-separate SQL statements passed into its 2nd argument,
-** in the context of the [database connection] passed in as its 1st
-** argument.  ^If the callback function of the 3rd argument to
-** sqlite3_exec() is not NULL, then it is invoked for each result row
-** coming out of the evaluated SQL statements.  ^The 4th argument to
-** sqlite3_exec() is relayed through to the 1st argument of each
-** callback invocation.  ^If the callback pointer to sqlite3_exec()
-** is NULL, then no callback is ever invoked and result rows are
-** ignored.
-**
-** ^If an error occurs while evaluating the SQL statements passed into
-** sqlite3_exec(), then execution of the current statement stops and
-** subsequent statements are skipped.  ^If the 5th parameter to sqlite3_exec()
-** is not NULL then any error message is written into memory obtained
-** from [sqlite3_malloc()] and passed back through the 5th parameter.
-** To avoid memory leaks, the application should invoke [sqlite3_free()]
-** on error message strings returned through the 5th parameter of
-** sqlite3_exec() after the error message string is no longer needed.
-** ^If the 5th parameter to sqlite3_exec() is not NULL and no errors
-** occur, then sqlite3_exec() sets the pointer in its 5th parameter to
-** NULL before returning.
-**
-** ^If an sqlite3_exec() callback returns non-zero, the sqlite3_exec()
-** routine returns SQLITE_ABORT without invoking the callback again and
-** without running any subsequent SQL statements.
-**
-** ^The 2nd argument to the sqlite3_exec() callback function is the
-** number of columns in the result.  ^The 3rd argument to the sqlite3_exec()
-** callback is an array of pointers to strings obtained as if from
-** [sqlite3_column_text()], one for each column.  ^If an element of a
-** result row is NULL then the corresponding string pointer for the
-** sqlite3_exec() callback is a NULL pointer.  ^The 4th argument to the
-** sqlite3_exec() callback is an array of pointers to strings where each
-** entry represents the name of corresponding result column as obtained
-** from [sqlite3_column_name()].
-**
-** ^If the 2nd parameter to sqlite3_exec() is a NULL pointer, a pointer
-** to an empty string, or a pointer that contains only whitespace and/or 
-** SQL comments, then no SQL statements are evaluated and the database
-** is not changed.
-**
-** Restrictions:
-**
-** <ul>
-** <li> The application must ensure that the 1st parameter to sqlite3_exec()
-**      is a valid and open [database connection].
-** <li> The application must not close the [database connection] specified by
-**      the 1st parameter to sqlite3_exec() while sqlite3_exec() is running.
-** <li> The application must not modify the SQL statement text passed into

-** CAPI3REF: OS Interface File Virtual Methods Object
-**
-** Every file opened by the [sqlite3_vfs.xOpen] method populates an
-** [sqlite3_file] object (or, more commonly, a subclass of the
-** [sqlite3_file] object) with a pointer to an instance of this object.
-** This object defines the methods used to perform various operations
-** against the open file represented by the [sqlite3_file] object.
-**
-** If the [sqlite3_vfs.xOpen] method sets the sqlite3_file.pMethods element 
-** to a non-NULL pointer, then the sqlite3_io_methods.xClose method
-** may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed.  The
-** only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
-** is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
-** to NULL.
-**
-** The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
-** [SQLITE_SYNC_FULL].  The first choice is the normal fsync().
-** The second choice is a Mac OS X style fullsync.  The [SQLITE_SYNC_DATAONLY]
-** flag may be ORed in to indicate that only the data of the file
-** and not its inode needs to be synced.
-**
-** The integer values to xLock() and xUnlock() are one of
-** <ul>
-** <li> [SQLITE_LOCK_NONE],
-** <li> [SQLITE_LOCK_SHARED],
-** <li> [SQLITE_LOCK_RESERVED],
-** <li> [SQLITE_LOCK_PENDING], or
-** <li> [SQLITE_LOCK_EXCLUSIVE].
-** </ul>
-** xLock() increases the lock. xUnlock() decreases the lock.
-** The xCheckReservedLock() method checks whether any database connection,
-** either in this process or in some other process, is holding a RESERVED,
-** PENDING, or EXCLUSIVE lock on the file.  It returns true
-** if such a lock exists and false otherwise.
-**
-** The xFileControl() method is a generic interface that allows custom
-** VFS implementations to directly control an open file using the
-** [sqlite3_file_control()] interface.  The second "op" argument is an
-** integer opcode.  The third argument is a generic pointer intended to
-** point to a structure that may contain arguments or space in which to
-** write return values.  Potential uses for xFileControl() might be
-** functions to enable blocking locks with timeouts, to change the
-** locking strategy (for example to use dot-file locks), to inquire
-** about the status of a lock, or to break stale locks.  The SQLite
-** core reserves all opcodes less than 100 for its own use.
-** A [file control opcodes | list of opcodes] less than 100 is available.
-** Applications that define a custom xFileControl method should use opcodes
-** greater than 100 to avoid conflicts.  VFS implementations should
-** return [SQLITE_NOTFOUND] for file control opcodes that they do not
-** recognize.
-**
-** The xSectorSize() method returns the sector size of the
-** device that underlies the file.  The sector size is the
-** minimum write that can be performed without disturbing
-** other bytes in the file.  The xDeviceCharacteristics()
-** method returns a bit vector describing behaviors of the
-** underlying device:
-**
-** <ul>
-** <li> [SQLITE_IOCAP_ATOMIC]
-** <li> [SQLITE_IOCAP_ATOMIC512]
-** <li> [SQLITE_IOCAP_ATOMIC1K]
-** <li> [SQLITE_IOCAP_ATOMIC2K]
-** <li> [SQLITE_IOCAP_ATOMIC4K]
-** <li> [SQLITE_IOCAP_ATOMIC8K]
-** <li> [SQLITE_IOCAP_ATOMIC16K]
-** <li> [SQLITE_IOCAP_ATOMIC32K]
-** <li> [SQLITE_IOCAP_ATOMIC64K]
-** <li> [SQLITE_IOCAP_SAFE_APPEND]
-** <li> [SQLITE_IOCAP_SEQUENTIAL]
-** <li> [SQLITE_IOCAP_UNDELETABLE_WHEN_OPEN]
-** <li> [SQLITE_IOCAP_POWERSAFE_OVERWRITE]
-** <li> [SQLITE_IOCAP_IMMUTABLE]
-** <li> [SQLITE_IOCAP_BATCH_ATOMIC]
-** </ul>
-**
-** The SQLITE_IOCAP_ATOMIC property means that all writes of
-** any size are atomic.  The SQLITE_IOCAP_ATOMICnnn values
-** mean that writes of blocks that are nnn bytes in size and
-** are aligned to an address which is an integer multiple of
-** nnn are atomic.  The SQLITE_IOCAP_SAFE_APPEND value means
-** that when data is appended to a file, the data is appended
-** first then the size of the file is extended, never the other
-** way around.  The SQLITE_IOCAP_SEQUENTIAL property means that
-** information is written to disk in the same order as calls
-** to xWrite().
-**
-** If xRead() returns SQLITE_IOERR_SHORT_READ it must also fill
-** in the unread portions of the buffer with zeros.  A VFS that
-** fails to zero-fill short reads might seem to work.  However,
-** failure to zero-fill short reads will eventually lead to
-** database corruption.

-** CAPI3REF: Standard File Control Opcodes
-** KEYWORDS: {file control opcodes} {file control opcode}
-**
-** These integer constants are opcodes for the xFileControl method
-** of the [sqlite3_io_methods] object and for the [sqlite3_file_control()]
-** interface.
-**
-** <ul>
-** <li>[[SQLITE_FCNTL_LOCKSTATE]]
-** The [SQLITE_FCNTL_LOCKSTATE] opcode is used for debugging.  This
-** opcode causes the xFileControl method to write the current state of
-** the lock (one of [SQLITE_LOCK_NONE], [SQLITE_LOCK_SHARED],
-** [SQLITE_LOCK_RESERVED], [SQLITE_LOCK_PENDING], or [SQLITE_LOCK_EXCLUSIVE])
-** into an integer that the pArg argument points to. This capability
-** is used during testing and is only available when the SQLITE_TEST
-** compile-time option is used.
-**
-** <li>[[SQLITE_FCNTL_SIZE_HINT]]
-** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS
-** layer a hint of how large the database file will grow to be during the
-** current transaction.  This hint is not guaranteed to be accurate but it
-** is often close.  The underlying VFS might choose to preallocate database
-** file space based on this hint in order to help writes to the database
-** file run faster.
-**
-** <li>[[SQLITE_FCNTL_CHUNK_SIZE]]
-** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS
-** extends and truncates the database file in chunks of a size specified
-** by the user. The fourth argument to [sqlite3_file_control()] should 
-** point to an integer (type int) containing the new chunk-size to use
-** for the nominated database. Allocating database file space in large
-** chunks (say 1MB at a time), may reduce file-system fragmentation and
-** improve performance on some systems.
-**
-** <li>[[SQLITE_FCNTL_FILE_POINTER]]
-** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer
-** to the [sqlite3_file] object associated with a particular database
-** connection.  See also [SQLITE_FCNTL_JOURNAL_POINTER].
-**
-** <li>[[SQLITE_FCNTL_JOURNAL_POINTER]]
-** The [SQLITE_FCNTL_JOURNAL_POINTER] opcode is used to obtain a pointer
-** to the [sqlite3_file] object associated with the journal file (either
-** the [rollback journal] or the [write-ahead log]) for a particular database
-** connection.  See also [SQLITE_FCNTL_FILE_POINTER].
-**
-** <li>[[SQLITE_FCNTL_SYNC_OMITTED]]
-** No longer in use.
-**
-** <li>[[SQLITE_FCNTL_SYNC]]
-** The [SQLITE_FCNTL_SYNC] opcode is generated internally by SQLite and
-** sent to the VFS immediately before the xSync method is invoked on a
-** database file descriptor. Or, if the xSync method is not invoked 
-** because the user has configured SQLite with 
-** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place 
-** of the xSync method. In most cases, the pointer argument passed with
-** this file-control is NULL. However, if the database file is being synced
-** as part of a multi-database commit, the argument points to a nul-terminated
-** string containing the transactions master-journal file name. VFSes that 
-** do not need this signal should silently ignore this opcode. Applications 
-** should not call [sqlite3_file_control()] with this opcode as doing so may 
-** disrupt the operation of the specialized VFSes that do require it.  
-**
-** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]]
-** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite
-** and sent to the VFS after a transaction has been committed immediately
-** but before the database is unlocked. VFSes that do not need this signal
-** should silently ignore this opcode. Applications should not call
-** [sqlite3_file_control()] with this opcode as doing so may disrupt the 
-** operation of the specialized VFSes that do require it.  
-**
-** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]]
-** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic
-** retry counts and intervals for certain disk I/O operations for the
-** windows [VFS] in order to provide robustness in the presence of
-** anti-virus programs.  By default, the windows VFS will retry file read,
-** file write, and file delete operations up to 10 times, with a delay
-** of 25 milliseconds before the first retry and with the delay increasing
-** by an additional 25 milliseconds with each subsequent retry.  This
-** opcode allows these two values (10 retries and 25 milliseconds of delay)
-** to be adjusted.  The values are changed for all database connections
-** within the same process.  The argument is a pointer to an array of two
-** integers where the first integer is the new retry count and the second
-** integer is the delay.  If either integer is negative, then the setting
-** is not changed but instead the prior value of that setting is written
-** into the array entry, allowing the current retry settings to be
-** interrogated.  The zDbName parameter is ignored.
-**
-** <li>[[SQLITE_FCNTL_PERSIST_WAL]]
-** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the
-** persistent [WAL | Write Ahead Log] setting.  By default, the auxiliary
-** write ahead log and shared memory files used for transaction control
-** are automatically deleted when the latest connection to the database
-** closes.  Setting persistent WAL mode causes those files to persist after
-** close.  Persisting the files is useful when other processes that do not
-** have write permission on the directory containing the database file want
-** to read the database file, as the WAL and shared memory files must exist
-** in order for the database to be readable.  The fourth parameter to
-** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
-** That integer is 0 to disable persistent WAL mode or 1 to enable persistent
-** WAL mode.  If the integer is -1, then it is overwritten with the current
-** WAL persistence setting.
-**
-** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]]
-** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the
-** persistent "powersafe-overwrite" or "PSOW" setting.  The PSOW setting
-** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the
-** xDeviceCharacteristics methods. The fourth parameter to
-** [sqlite3_file_control()] for this opcode should be a pointer to an integer.
-** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage
-** mode.  If the integer is -1, then it is overwritten with the current
-** zero-damage mode setting.
-**
-** <li>[[SQLITE_FCNTL_OVERWRITE]]
-** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening
-** a write transaction to indicate that, unless it is rolled back for some
-** reason, the entire database file will be overwritten by the current 
-** transaction. This is used by VACUUM operations.
-**
-** <li>[[SQLITE_FCNTL_VFSNAME]]
-** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of
-** all [VFSes] in the VFS stack.  The names are of all VFS shims and the
-** final bottom-level VFS are written into memory obtained from 
-** [sqlite3_malloc()] and the result is stored in the char* variable
-** that the fourth parameter of [sqlite3_file_control()] points to.
-** The caller is responsible for freeing the memory when done.  As with
-** all file-control actions, there is no guarantee that this will actually
-** do anything.  Callers should initialize the char* variable to a NULL
-** pointer in case this file-control is not implemented.  This file-control
-** is intended for diagnostic use only.
-**
-** <li>[[SQLITE_FCNTL_VFS_POINTER]]
-** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level
-** [VFSes] currently in use.  ^(The argument X in
-** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be
-** of type "[sqlite3_vfs] **".  This opcodes will set *X
-** to a pointer to the top-level VFS.)^
-** ^When there are multiple VFS shims in the stack, this opcode finds the
-** upper-most shim only.
-**
-** <li>[[SQLITE_FCNTL_PRAGMA]]
-** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA] 
-** file control is sent to the open [sqlite3_file] object corresponding
-** to the database file to which the pragma statement refers. ^The argument
-** to the [SQLITE_FCNTL_PRAGMA] file control is an array of
-** pointers to strings (char**) in which the second element of the array
-** is the name of the pragma and the third element is the argument to the
-** pragma or NULL if the pragma has no argument.  ^The handler for an
-** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element
-** of the char** argument point to a string obtained from [sqlite3_mprintf()]
-** or the equivalent and that string will become the result of the pragma or
-** the error message if the pragma fails. ^If the
-** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal 
-** [PRAGMA] processing continues.  ^If the [SQLITE_FCNTL_PRAGMA]
-** file control returns [SQLITE_OK], then the parser assumes that the
-** VFS has handled the PRAGMA itself and the parser generates a no-op
-** prepared statement if result string is NULL, or that returns a copy
-** of the result string if the string is non-NULL.
-** ^If the [SQLITE_FCNTL_PRAGMA] file control returns
-** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means
-** that the VFS encountered an error while handling the [PRAGMA] and the
-** compilation of the PRAGMA fails with an error.  ^The [SQLITE_FCNTL_PRAGMA]
-** file control occurs at the beginning of pragma statement analysis and so
-** it is able to override built-in [PRAGMA] statements.
-**
-** <li>[[SQLITE_FCNTL_BUSYHANDLER]]
-** ^The [SQLITE_FCNTL_BUSYHANDLER]
-** file-control may be invoked by SQLite on the database file handle
-** shortly after it is opened in order to provide a custom VFS with access
-** to the connections busy-handler callback. The argument is of type (void **)
-** - an array of two (void *) values. The first (void *) actually points
-** to a function of type (int (*)(void *)). In order to invoke the connections
-** busy-handler, this function should be invoked with the second (void *) in
-** the array as the only argument. If it returns non-zero, then the operation
-** should be retried. If it returns zero, the custom VFS should abandon the
-** current operation.
-**
-** <li>[[SQLITE_FCNTL_TEMPFILENAME]]
-** ^Application can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control
-** to have SQLite generate a
-** temporary filename using the same algorithm that is followed to generate
-** temporary filenames for TEMP tables and other internal uses.  The
-** argument should be a char** which will be filled with the filename
-** written into memory obtained from [sqlite3_malloc()].  The caller should
-** invoke [sqlite3_free()] on the result to avoid a memory leak.
-**
-** <li>[[SQLITE_FCNTL_MMAP_SIZE]]
-** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the
-** maximum number of bytes that will be used for memory-mapped I/O.
-** The argument is a pointer to a value of type sqlite3_int64 that
-** is an advisory maximum number of bytes in the file to memory map.  The
-** pointer is overwritten with the old value.  The limit is not changed if
-** the value originally pointed to is negative, and so the current limit 
-** can be queried by passing in a pointer to a negative number.  This
-** file-control is used internally to implement [PRAGMA mmap_size].
-**
-** <li>[[SQLITE_FCNTL_TRACE]]
-** The [SQLITE_FCNTL_TRACE] file control provides advisory information
-** to the VFS about what the higher layers of the SQLite stack are doing.
-** This file control is used by some VFS activity tracing [shims].
-** The argument is a zero-terminated string.  Higher layers in the
-** SQLite stack may generate instances of this file control if
-** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled.
-**
-** <li>[[SQLITE_FCNTL_HAS_MOVED]]
-** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a
-** pointer to an integer and it writes a boolean into that integer depending
-** on whether or not the file has been renamed, moved, or deleted since it
-** was first opened.
-**
-** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]]
-** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the
-** underlying native file handle associated with a file handle.  This file
-** control interprets its argument as a pointer to a native file handle and
-** writes the resulting value there.
-**
-** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]]
-** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging.  This
-** opcode causes the xFileControl method to swap the file handle with the one
-** pointed to by the pArg argument.  This capability is used during testing
-** and only needs to be supported when SQLITE_TEST is defined.
-**
-** <li>[[SQLITE_FCNTL_WAL_BLOCK]]
-** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might
-** be advantageous to block on the next WAL lock if the lock is not immediately
-** available.  The WAL subsystem issues this signal during rare
-** circumstances in order to fix a problem with priority inversion.
-** Applications should <em>not</em> use this file-control.
-**
-** <li>[[SQLITE_FCNTL_ZIPVFS]]
-** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other
-** VFS should return SQLITE_NOTFOUND for this opcode.
-**
-** <li>[[SQLITE_FCNTL_RBU]]
-** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by
-** the RBU extension only.  All other VFS should return SQLITE_NOTFOUND for
-** this opcode.  
-**
-** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]]
-** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then
-** the file descriptor is placed in "batch write mode", which
-** means all subsequent write operations will be deferred and done
-** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE].  Systems
-** that do not support batch atomic writes will return SQLITE_NOTFOUND.
-** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to
-** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or
-** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make
-** no VFS interface calls on the same [sqlite3_file] file descriptor
-** except for calls to the xWrite method and the xFileControl method
-** with [SQLITE_FCNTL_SIZE_HINT].
-**
-** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]]
-** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write
-** operations since the previous successful call to 
-** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically.
-** This file control returns [SQLITE_OK] if and only if the writes were
-** all performed successfully and have been committed to persistent storage.
-** ^Regardless of whether or not it is successful, this file control takes
-** the file descriptor out of batch write mode so that all subsequent
-** write operations are independent.
-** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without
-** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
-**
-** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]]
-** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write
-** operations since the previous successful call to 
-** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back.
-** ^This file control takes the file descriptor out of batch write mode
-** so that all subsequent write operations are independent.
-** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without
-** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE].
-**
-** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]]
-** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode causes attempts to obtain
-** a file lock using the xLock or xShmLock methods of the VFS to wait
-** for up to M milliseconds before failing, where M is the single 
-** unsigned integer parameter.

-** CAPI3REF: OS Interface Object
-**
-** An instance of the sqlite3_vfs object defines the interface between
-** the SQLite core and the underlying operating system.  The "vfs"
-** in the name of the object stands for "virtual file system".  See
-** the [VFS | VFS documentation] for further information.
-**
-** The VFS interface is sometimes extended by adding new methods onto
-** the end.  Each time such an extension occurs, the iVersion field
-** is incremented.  The iVersion value started out as 1 in
-** SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
-** with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
-** to 3 with SQLite [version 3.7.6] on [dateof:3.7.6].  Additional fields
-** may be appended to the sqlite3_vfs object and the iVersion value
-** may increase again in future versions of SQLite.
-** Note that the structure
-** of the sqlite3_vfs object changes in the transition from
-** SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
-** and yet the iVersion field was not modified.
-**
-** The szOsFile field is the size of the subclassed [sqlite3_file]
-** structure used by this VFS.  mxPathname is the maximum length of
-** a pathname in this VFS.
-**
-** Registered sqlite3_vfs objects are kept on a linked list formed by
-** the pNext pointer.  The [sqlite3_vfs_register()]
-** and [sqlite3_vfs_unregister()] interfaces manage this list
-** in a thread-safe way.  The [sqlite3_vfs_find()] interface
-** searches the list.  Neither the application code nor the VFS
-** implementation should use the pNext pointer.
-**
-** The pNext field is the only field in the sqlite3_vfs
-** structure that SQLite will ever modify.  SQLite will only access
-** or modify this field while holding a particular static mutex.
-** The application should never modify anything within the sqlite3_vfs
-** object once the object has been registered.
-**
-** The zName field holds the name of the VFS module.  The name must
-** be unique across all VFS modules.
-**
-** [[sqlite3_vfs.xOpen]]
-** ^SQLite guarantees that the zFilename parameter to xOpen
-** is either a NULL pointer or string obtained
-** from xFullPathname() with an optional suffix added.
-** ^If a suffix is added to the zFilename parameter, it will
-** consist of a single "-" character followed by no more than
-** 11 alphanumeric and/or "-" characters.
-** ^SQLite further guarantees that
-** the string will be valid and unchanged until xClose() is
-** called. Because of the previous sentence,
-** the [sqlite3_file] can safely store a pointer to the
-** filename if it needs to remember the filename for some reason.
-** If the zFilename parameter to xOpen is a NULL pointer then xOpen
-** must invent its own temporary name for the file.  ^Whenever the 
-** xFilename parameter is NULL it will also be the case that the
-** flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
-**
-** The flags argument to xOpen() includes all bits set in
-** the flags argument to [sqlite3_open_v2()].  Or if [sqlite3_open()]
-** or [sqlite3_open16()] is used, then flags includes at least
-** [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE]. 
-** If xOpen() opens a file read-only then it sets *pOutFlags to
-** include [SQLITE_OPEN_READONLY].  Other bits in *pOutFlags may be set.
-**
-** ^(SQLite will also add one of the following flags to the xOpen()
-** call, depending on the object being opened:
-**
-** <ul>
-** <li>  [SQLITE_OPEN_MAIN_DB]
-** <li>  [SQLITE_OPEN_MAIN_JOURNAL]
-** <li>  [SQLITE_OPEN_TEMP_DB]
-** <li>  [SQLITE_OPEN_TEMP_JOURNAL]
-** <li>  [SQLITE_OPEN_TRANSIENT_DB]
-** <li>  [SQLITE_OPEN_SUBJOURNAL]
-** <li>  [SQLITE_OPEN_MASTER_JOURNAL]
-** <li>  [SQLITE_OPEN_WAL]
-** </ul>)^
-**
-** The file I/O implementation can use the object type flags to
-** change the way it deals with files.  For example, an application
-** that does not care about crash recovery or rollback might make
-** the open of a journal file a no-op.  Writes to this journal would
-** also be no-ops, and any attempt to read the journal would return
-** SQLITE_IOERR.  Or the implementation might recognize that a database
-** file will be doing page-aligned sector reads and writes in a random
-** order and set up its I/O subsystem accordingly.
-**
-** SQLite might also add one of the following flags to the xOpen method:
-**
-** <ul>
-** <li> [SQLITE_OPEN_DELETEONCLOSE]
-** <li> [SQLITE_OPEN_EXCLUSIVE]
-** </ul>
-**
-** The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
-** deleted when it is closed.  ^The [SQLITE_OPEN_DELETEONCLOSE]
-** will be set for TEMP databases and their journals, transient
-** databases, and subjournals.
-**
-** ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
-** with the [SQLITE_OPEN_CREATE] flag, which are both directly
-** analogous to the O_EXCL and O_CREAT flags of the POSIX open()
-** API.  The SQLITE_OPEN_EXCLUSIVE flag, when paired with the 
-** SQLITE_OPEN_CREATE, is used to indicate that file should always
-** be created, and that it is an error if it already exists.
-** It is <i>not</i> used to indicate the file should be opened 
-** for exclusive access.
-**
-** ^At least szOsFile bytes of memory are allocated by SQLite
-** to hold the  [sqlite3_file] structure passed as the third
-** argument to xOpen.  The xOpen method does not have to
-** allocate the structure; it should just fill it in.  Note that
-** the xOpen method must set the sqlite3_file.pMethods to either
-** a valid [sqlite3_io_methods] object or to NULL.  xOpen must do
-** this even if the open fails.  SQLite expects that the sqlite3_file.pMethods
-** element will be valid after xOpen returns regardless of the success
-** or failure of the xOpen call.
-**
-** [[sqlite3_vfs.xAccess]]
-** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
-** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
-** test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
-** to test whether a file is at least readable.   The file can be a
-** directory.
-**
-** ^SQLite will always allocate at least mxPathname+1 bytes for the
-** output buffer xFullPathname.  The exact size of the output buffer
-** is also passed as a parameter to both  methods. If the output buffer
-** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
-** handled as a fatal error by SQLite, vfs implementations should endeavor
-** to prevent this by setting mxPathname to a sufficiently large value.
-**
-** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
-** interfaces are not strictly a part of the filesystem, but they are
-** included in the VFS structure for completeness.
-** The xRandomness() function attempts to return nBytes bytes
-** of good-quality randomness into zOut.  The return value is
-** the actual number of bytes of randomness obtained.
-** The xSleep() method causes the calling thread to sleep for at
-** least the number of microseconds given.  ^The xCurrentTime()
-** method returns a Julian Day Number for the current date and time as
-** a floating point value.
-** ^The xCurrentTimeInt64() method returns, as an integer, the Julian
-** Day Number multiplied by 86400000 (the number of milliseconds in 
-** a 24-hour day).  
-** ^SQLite will use the xCurrentTimeInt64() method to get the current
-** date and time if that method is available (if iVersion is 2 or 
-** greater and the function pointer is not NULL) and will fall back
-** to xCurrentTime() if xCurrentTimeInt64() is unavailable.
-**
-** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
-** are not used by the SQLite core.  These optional interfaces are provided
-** by some VFSes to facilitate testing of the VFS code. By overriding 
-** system calls with functions under its control, a test program can
-** simulate faults and error conditions that would otherwise be difficult
-** or impossible to induce.  The set of system calls that can be overridden
-** varies from one VFS to another, and from one version of the same VFS to the
-** next.  Applications that use these interfaces must be prepared for any
-** or all of these interfaces to be NULL or for their behavior to change
-** from one release to the next.  Applications must not attempt to access
-** any of these methods if the iVersion of the VFS is less than 3.

-** deallocates any resources that were allocated by sqlite3_initialize().
-** These routines are designed to aid in process initialization and
-** shutdown on embedded systems.  Workstation applications using
-** SQLite normally do not need to invoke either of these routines.
-**
-** A call to sqlite3_initialize() is an "effective" call if it is
-** the first time sqlite3_initialize() is invoked during the lifetime of
-** the process, or if it is the first time sqlite3_initialize() is invoked
-** following a call to sqlite3_shutdown().  ^(Only an effective call
-** of sqlite3_initialize() does any initialization.  All other calls
-** are harmless no-ops.)^
-**

-** call to sqlite3_shutdown() since the last sqlite3_initialize().  ^(Only
-** an effective call to sqlite3_shutdown() does any deinitialization.
-** All other valid calls to sqlite3_shutdown() are harmless no-ops.)^
-**
-** The sqlite3_initialize() interface is threadsafe, but sqlite3_shutdown()
-** is not.  The sqlite3_shutdown() interface must only be called from a
-** single thread.  All open [database connections] must be closed and all
-** other SQLite resources must be deallocated prior to invoking
-** sqlite3_shutdown().
-**
-** Among other things, ^sqlite3_initialize() will invoke
-** sqlite3_os_init().  Similarly, ^sqlite3_shutdown()
-** will invoke sqlite3_os_end().
-**
-** ^The sqlite3_initialize() routine returns [SQLITE_OK] on success.
-** ^If for some reason, sqlite3_initialize() is unable to initialize
-** the library (perhaps it is unable to allocate a needed resource such
-** as a mutex) it returns an [error code] other than [SQLITE_OK].
-**
-** ^The sqlite3_initialize() routine is called internally by many other
-** SQLite interfaces so that an application usually does not need to
-** invoke sqlite3_initialize() directly.  For example, [sqlite3_open()]
-** calls sqlite3_initialize() so the SQLite library will be automatically
-** initialized when [sqlite3_open()] is called if it has not be initialized
-** already.  ^However, if SQLite is compiled with the [SQLITE_OMIT_AUTOINIT]
-** compile-time option, then the automatic calls to sqlite3_initialize()
-** are omitted and the application must call sqlite3_initialize() directly
-** prior to using any other SQLite interface.  For maximum portability,
-** it is recommended that applications always invoke sqlite3_initialize()
-** directly prior to using any other SQLite interface.  Future releases
-** of SQLite may require this.  In other words, the behavior exhibited
-** when SQLite is compiled with [SQLITE_OMIT_AUTOINIT] might become the
-** default behavior in some future release of SQLite.
-**
-** The sqlite3_os_init() routine does operating-system specific
-** initialization of the SQLite library.  The sqlite3_os_end()
-** routine undoes the effect of sqlite3_os_init().  Typical tasks
-** performed by these routines include allocation or deallocation
-** of static resources, initialization of global variables,

-** A pointer to an instance of this object is the argument to

-** By creating an instance of this object
-** and passing it to [sqlite3_config]([SQLITE_CONFIG_MALLOC])
-** during configuration, an application can specify an alternative
-** memory allocation subsystem for SQLite to use for all of its

-**
-** Note that SQLite comes with several [built-in memory allocators]
-** that are perfectly adequate for the overwhelming majority of applications
-** and that this object is only useful to a tiny minority of applications
-** with specialized memory allocation requirements.  This object is
-** also used during testing of SQLite in order to specify an alternative
-** memory allocator that simulates memory out-of-memory conditions in
-** order to verify that SQLite recovers gracefully from such
-** conditions.
-**
-** The xMalloc, xRealloc, and xFree methods must work like the
-** malloc(), realloc() and free() functions from the standard C library.
-** ^SQLite guarantees that the second argument to
-** xRealloc is always a value returned by a prior call to xRoundup.
-**
-** xSize should return the allocated size of a memory allocation
-** previously obtained from xMalloc or xRealloc.  The allocated size
-** is always at least as big as the requested size but may be larger.
-**
-** The xRoundup method returns what would be the allocated size of
-** a memory allocation given a particular requested size.  Most memory
-** allocators round up memory allocations at least to the next multiple
-** of 8.  Some allocators round up to a larger multiple or to a power of 2.
-** Every memory allocation request coming in through [sqlite3_malloc()]
-** or [sqlite3_realloc()] first calls xRoundup.  If xRoundup returns 0, 
-** that causes the corresponding memory allocation to fail.
-**
-** The xInit method initializes the memory allocator.  For example,
-** it might allocate any require mutexes or initialize internal data
-** structures.  The xShutdown method is invoked (indirectly) by

-** ^The sqlite3_last_insert_rowid(D) interface usually returns the [rowid] of

-** on database connection D. ^Inserts into [WITHOUT ROWID] tables are not
-** recorded. ^If no successful [INSERT]s into rowid tables have ever occurred 
-** on the database connection D, then sqlite3_last_insert_rowid(D) returns

-**
-** As well as being set automatically as rows are inserted into database
-** tables, the value returned by this function may be set explicitly by
-** [sqlite3_set_last_insert_rowid()]
-**
-** Some virtual table implementations may INSERT rows into rowid tables as

-**
-** ^The first argument to the busy handler is a copy of the void* pointer which

-** CAPI3REF: Convenience Routines For Running Queries
-** METHOD: sqlite3
-**
-** This is a legacy interface that is preserved for backwards compatibility.
-** Use of this interface is not recommended.
-**
-** Definition: A <b>result table</b> is memory data structure created by the
-** [sqlite3_get_table()] interface.  A result table records the
-** complete query results from one or more queries.
-**
-** The table conceptually has a number of rows and columns.  But
-** these numbers are not part of the result table itself.  These
-** numbers are obtained separately.  Let N be the number of rows
-** and M be the number of columns.
-**
-** A result table is an array of pointers to zero-terminated UTF-8 strings.
-** There are (N+1)*M elements in the array.  The first M pointers point
-** to zero-terminated strings that  contain the names of the columns.
-** The remaining entries all point to query results.  NULL values result
-** in NULL pointers.  All other values are in their UTF-8 zero-terminated
-** string representation as returned by [sqlite3_column_text()].
-**
-** A result table might consist of one or more memory allocations.
-** It is not safe to pass a result table directly to [sqlite3_free()].
-** A result table should be deallocated using [sqlite3_free_table()].
-**
-** ^(As an example of the result table format, suppose a query result
-** is as follows:
-**
-** <blockquote><pre>
-**        Name        | Age
-**        -----------------------
-**        Alice       | 43
-**        Bob         | 28
-**        Cindy       | 21
-** </pre></blockquote>
-**
-** There are two column (M==2) and three rows (N==3).  Thus the
-** result table has 8 entries.  Suppose the result table is stored
-** in an array names azResult.  Then azResult holds this content:
-**
-** <blockquote><pre>
-**        azResult&#91;0] = "Name";
-**        azResult&#91;1] = "Age";
-**        azResult&#91;2] = "Alice";
-**        azResult&#91;3] = "43";
-**        azResult&#91;4] = "Bob";
-**        azResult&#91;5] = "28";
-**        azResult&#91;6] = "Cindy";
-**        azResult&#91;7] = "21";
-** </pre></blockquote>)^
-**
-** ^The sqlite3_get_table() function evaluates one or more
-** semicolon-separated SQL statements in the zero-terminated UTF-8
-** string of its 2nd parameter and returns a result table to the
-** pointer given in its 3rd parameter.
-**

-** function must not try to call [sqlite3_free()] directly.  Only

-**
-** The sqlite3_get_table() interface is implemented as a wrapper around
-** [sqlite3_exec()].  The sqlite3_get_table() routine does not have access
-** to any internal data structures of SQLite.  It uses only the public

-** CAPI3REF: Compile-Time Authorization Callbacks
-** METHOD: sqlite3
-** KEYWORDS: {authorizer callback}
-**
-** ^This routine registers an authorizer callback with a particular
-** [database connection], supplied in the first argument.
-** ^The authorizer callback is invoked as SQL statements are being compiled
-** by [sqlite3_prepare()] or its variants [sqlite3_prepare_v2()],
-** [sqlite3_prepare_v3()], [sqlite3_prepare16()], [sqlite3_prepare16_v2()],
-** and [sqlite3_prepare16_v3()].  ^At various
-** points during the compilation process, as logic is being created
-** to perform various actions, the authorizer callback is invoked to
-** see if those actions are allowed.  ^The authorizer callback should
-** return [SQLITE_OK] to allow the action, [SQLITE_IGNORE] to disallow the
-** specific action but allow the SQL statement to continue to be
-** compiled, or [SQLITE_DENY] to cause the entire SQL statement to be
-** rejected with an error.  ^If the authorizer callback returns
-** any value other than [SQLITE_IGNORE], [SQLITE_OK], or [SQLITE_DENY]
-** then the [sqlite3_prepare_v2()] or equivalent call that triggered
-** the authorizer will fail with an error message.
-**
-** When the callback returns [SQLITE_OK], that means the operation
-** requested is ok.  ^When the callback returns [SQLITE_DENY], the
-** [sqlite3_prepare_v2()] or equivalent call that triggered the
-** authorizer will fail with an error message explaining that
-** access is denied. 
-**
-** ^The first parameter to the authorizer callback is a copy of the third
-** parameter to the sqlite3_set_authorizer() interface. ^The second parameter
-** to the callback is an integer [SQLITE_COPY | action code] that specifies
-** the particular action to be authorized. ^The third through sixth parameters
-** to the callback are either NULL pointers or zero-terminated strings
-** that contain additional details about the action to be authorized.
-** Applications must always be prepared to encounter a NULL pointer in any
-** of the third through the sixth parameters of the authorization callback.
-**
-** ^If the action code is [SQLITE_READ]
-** and the callback returns [SQLITE_IGNORE] then the
-** [prepared statement] statement is constructed to substitute
-** a NULL value in place of the table column that would have
-** been read if [SQLITE_OK] had been returned.  The [SQLITE_IGNORE]
-** return can be used to deny an untrusted user access to individual
-** columns of a table.
-** ^When a table is referenced by a [SELECT] but no column values are
-** extracted from that table (for example in a query like
-** "SELECT count(*) FROM tab") then the [SQLITE_READ] authorizer callback
-** is invoked once for that table with a column name that is an empty string.
-** ^If the action code is [SQLITE_DELETE] and the callback returns
-** [SQLITE_IGNORE] then the [DELETE] operation proceeds but the
-** [truncate optimization] is disabled and all rows are deleted individually.
-**
-** An authorizer is used when [sqlite3_prepare | preparing]
-** SQL statements from an untrusted source, to ensure that the SQL statements
-** do not try to access data they are not allowed to see, or that they do not
-** try to execute malicious statements that damage the database.  For
-** example, an application may allow a user to enter arbitrary
-** SQL queries for evaluation by a database.  But the application does
-** not want the user to be able to make arbitrary changes to the
-** database.  An authorizer could then be put in place while the
-** user-entered SQL is being [sqlite3_prepare | prepared] that
-** disallows everything except [SELECT] statements.
-**
-** Applications that need to process SQL from untrusted sources
-** might also consider lowering resource limits using [sqlite3_limit()]
-** and limiting database size using the [max_page_count] [PRAGMA]
-** in addition to using an authorizer.
-**
-** ^(Only a single authorizer can be in place on a database connection
-** at a time.  Each call to sqlite3_set_authorizer overrides the
-** previous call.)^  ^Disable the authorizer by installing a NULL callback.
-** The authorizer is disabled by default.
-**
-** The authorizer callback must not do anything that will modify
-** the database connection that invoked the authorizer callback.
-** Note that [sqlite3_prepare_v2()] and [sqlite3_step()] both modify their
-** database connections for the meaning of "modify" in this paragraph.
-**
-** ^When [sqlite3_prepare_v2()] is used to prepare a statement, the
-** statement might be re-prepared during [sqlite3_step()] due to a 
-** schema change.  Hence, the application should ensure that the
-** correct authorizer callback remains in place during the [sqlite3_step()].
-**
-** ^Note that the authorizer callback is invoked only during
-** [sqlite3_prepare()] or its variants.  Authorization is not
-** performed during statement evaluation in [sqlite3_step()], unless
-** as stated in the previous paragraph, sqlite3_step() invokes
-** sqlite3_prepare_v2() to reprepare a statement after a schema change.

-** then it is interpreted as an absolute path. ^If the path does not begin 
-** with a '/' (meaning that the authority section is omitted from the URI)
-** then the path is interpreted as a relative path. 
-** ^(On windows, the first component of an absolute path 
-** is a drive specification (e.g. "C:").)^
-**
-** [[core URI query parameters]]
-** The query component of a URI may contain parameters that are interpreted
-** either by SQLite itself, or by a [VFS | custom VFS implementation].
-** SQLite and its built-in [VFSes] interpret the
-** following query parameters:
-**
-** <ul>
-**   <li> <b>vfs</b>: ^The "vfs" parameter may be used to specify the name of
-**     a VFS object that provides the operating system interface that should
-**     be used to access the database file on disk. ^If this option is set to
-**     an empty string the default VFS object is used. ^Specifying an unknown
-**     VFS is an error. ^If sqlite3_open_v2() is used and the vfs option is
-**     present, then the VFS specified by the option takes precedence over
-**     the value passed as the fourth parameter to sqlite3_open_v2().
-**
-**   <li> <b>mode</b>: ^(The mode parameter may be set to either "ro", "rw",
-**     "rwc", or "memory". Attempting to set it to any other value is
-**     an error)^. 
-**     ^If "ro" is specified, then the database is opened for read-only 
-**     access, just as if the [SQLITE_OPEN_READONLY] flag had been set in the 
-**     third argument to sqlite3_open_v2(). ^If the mode option is set to 
-**     "rw", then the database is opened for read-write (but not create) 
-**     access, as if SQLITE_OPEN_READWRITE (but not SQLITE_OPEN_CREATE) had 
-**     been set. ^Value "rwc" is equivalent to setting both 
-**     SQLITE_OPEN_READWRITE and SQLITE_OPEN_CREATE.  ^If the mode option is
-**     set to "memory" then a pure [in-memory database] that never reads
-**     or writes from disk is used. ^It is an error to specify a value for
-**     the mode parameter that is less restrictive than that specified by
-**     the flags passed in the third parameter to sqlite3_open_v2().
-**
-**   <li> <b>cache</b>: ^The cache parameter may be set to either "shared" or
-**     "private". ^Setting it to "shared" is equivalent to setting the
-**     SQLITE_OPEN_SHAREDCACHE bit in the flags argument passed to
-**     sqlite3_open_v2(). ^Setting the cache parameter to "private" is 
-**     equivalent to setting the SQLITE_OPEN_PRIVATECACHE bit.
-**     ^If sqlite3_open_v2() is used and the "cache" parameter is present in
-**     a URI filename, its value overrides any behavior requested by setting
-**     SQLITE_OPEN_PRIVATECACHE or SQLITE_OPEN_SHAREDCACHE flag.
-**
-**  <li> <b>psow</b>: ^The psow parameter indicates whether or not the
-**     [powersafe overwrite] property does or does not apply to the
-**     storage media on which the database file resides.
-**
-**  <li> <b>nolock</b>: ^The nolock parameter is a boolean query parameter
-**     which if set disables file locking in rollback journal modes.  This
-**     is useful for accessing a database on a filesystem that does not
-**     support locking.  Caution:  Database corruption might result if two
-**     or more processes write to the same database and any one of those
-**     processes uses nolock=1.
-**
-**  <li> <b>immutable</b>: ^The immutable parameter is a boolean query
-**     parameter that indicates that the database file is stored on
-**     read-only media.  ^When immutable is set, SQLite assumes that the
-**     database file cannot be changed, even by a process with higher
-**     privilege, and so the database is opened read-only and all locking
-**     and change detection is disabled.  Caution: Setting the immutable
-**     property on a database file that does in fact change can result
-**     in incorrect query results and/or [SQLITE_CORRUPT] errors.
-**     See also: [SQLITE_IOCAP_IMMUTABLE].
-**       
-** </ul>
-**
-** ^Specifying an unknown parameter in the query component of a URI is not an
-** error.  Future versions of SQLite might understand additional query
-** parameters.  See "[query parameters with special meaning to SQLite]" for
-** additional information.

-** CAPI3REF: Compiling An SQL Statement
-** KEYWORDS: {SQL statement compiler}
-** METHOD: sqlite3
-** CONSTRUCTOR: sqlite3_stmt
-**
-** To execute an SQL statement, it must first be compiled into a byte-code
-** program using one of these routines.  Or, in other words, these routines
-** are constructors for the [prepared statement] object.
-**
-** The preferred routine to use is [sqlite3_prepare_v2()].  The
-** [sqlite3_prepare()] interface is legacy and should be avoided.
-** [sqlite3_prepare_v3()] has an extra "prepFlags" option that is used
-** for special purposes.
-**
-** The use of the UTF-8 interfaces is preferred, as SQLite currently
-** does all parsing using UTF-8.  The UTF-16 interfaces are provided
-** as a convenience.  The UTF-16 interfaces work by converting the
-** input text into UTF-8, then invoking the corresponding UTF-8 interface.
-**
-** The first argument, "db", is a [database connection] obtained from a
-** prior successful call to [sqlite3_open()], [sqlite3_open_v2()] or
-** [sqlite3_open16()].  The database connection must not have been closed.
-**
-** The second argument, "zSql", is the statement to be compiled, encoded
-** as either UTF-8 or UTF-16.  The sqlite3_prepare(), sqlite3_prepare_v2(),
-** and sqlite3_prepare_v3()
-** interfaces use UTF-8, and sqlite3_prepare16(), sqlite3_prepare16_v2(),
-** and sqlite3_prepare16_v3() use UTF-16.
-**
-** ^If the nByte argument is negative, then zSql is read up to the
-** first zero terminator. ^If nByte is positive, then it is the
-** number of bytes read from zSql.  ^If nByte is zero, then no prepared
-** statement is generated.
-** If the caller knows that the supplied string is nul-terminated, then
-** there is a small performance advantage to passing an nByte parameter that
-** is the number of bytes in the input string <i>including</i>
-** the nul-terminator.
-**
-** ^If pzTail is not NULL then *pzTail is made to point to the first byte
-** past the end of the first SQL statement in zSql.  These routines only
-** compile the first statement in zSql, so *pzTail is left pointing to
-** what remains uncompiled.
-**
-** ^*ppStmt is left pointing to a compiled [prepared statement] that can be
-** executed using [sqlite3_step()].  ^If there is an error, *ppStmt is set
-** to NULL.  ^If the input text contains no SQL (if the input is an empty
-** string or a comment) then *ppStmt is set to NULL.
-** The calling procedure is responsible for deleting the compiled
-** SQL statement using [sqlite3_finalize()] after it has finished with it.
-** ppStmt may not be NULL.
-**
-** ^On success, the sqlite3_prepare() family of routines return [SQLITE_OK];
-** otherwise an [error code] is returned.
-**
-** The sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16_v2(),
-** and sqlite3_prepare16_v3() interfaces are recommended for all new programs.
-** The older interfaces (sqlite3_prepare() and sqlite3_prepare16())
-** are retained for backwards compatibility, but their use is discouraged.
-** ^In the "vX" interfaces, the prepared statement
-** that is returned (the [sqlite3_stmt] object) contains a copy of the
-** original SQL text. This causes the [sqlite3_step()] interface to
-** behave differently in three ways:
-**
-** <ol>
-** <li>
-** ^If the database schema changes, instead of returning [SQLITE_SCHEMA] as it
-** always used to do, [sqlite3_step()] will automatically recompile the SQL
-** statement and try to run it again. As many as [SQLITE_MAX_SCHEMA_RETRY]
-** retries will occur before sqlite3_step() gives up and returns an error.
-** </li>
-**
-** <li>
-** ^When an error occurs, [sqlite3_step()] will return one of the detailed
-** [error codes] or [extended error codes].  ^The legacy behavior was that
-** [sqlite3_step()] would only return a generic [SQLITE_ERROR] result code
-** and the application would have to make a second call to [sqlite3_reset()]
-** in order to find the underlying cause of the problem. With the "v2" prepare
-** interfaces, the underlying reason for the error is returned immediately.
-** </li>
-**
-** <li>
-** ^If the specific value bound to [parameter | host parameter] in the 
-** WHERE clause might influence the choice of query plan for a statement,
-** then the statement will be automatically recompiled, as if there had been 
-** a schema change, on the first  [sqlite3_step()] call following any change
-** to the [sqlite3_bind_text | bindings] of that [parameter]. 
-** ^The specific value of WHERE-clause [parameter] might influence the 
-** choice of query plan if the parameter is the left-hand side of a [LIKE]
-** or [GLOB] operator or if the parameter is compared to an indexed column
-** and the [SQLITE_ENABLE_STAT3] compile-time option is enabled.
-** </li>
-** </ol>
-**
-** <p>^sqlite3_prepare_v3() differs from sqlite3_prepare_v2() only in having
-** the extra prepFlags parameter, which is a bit array consisting of zero or
-** more of the [SQLITE_PREPARE_PERSISTENT|SQLITE_PREPARE_*] flags.  ^The
-** sqlite3_prepare_v2() interface works exactly the same as
-** sqlite3_prepare_v3() with a zero prepFlags parameter.

-** and VVV represents an alphanumeric identifier.)^  ^The values of these
-** parameters (also called "host parameter names" or "SQL parameters")
-** can be set using the sqlite3_bind_*() routines defined here.
-**
-** ^The first argument to the sqlite3_bind_*() routines is always
-** a pointer to the [sqlite3_stmt] object returned from
-** [sqlite3_prepare_v2()] or its variants.
-**
-** ^The second argument is the index of the SQL parameter to be set.
-** ^The leftmost SQL parameter has an index of 1.  ^When the same named
-** SQL parameter is used more than once, second and subsequent
-** occurrences have the same index as the first occurrence.
-** ^The index for named parameters can be looked up using the
-** [sqlite3_bind_parameter_index()] API if desired.  ^The index
-** for "?NNN" parameters is the value of NNN.
-** ^The NNN value must be between 1 and the [sqlite3_limit()]
-** parameter [SQLITE_LIMIT_VARIABLE_NUMBER] (default value: 999).
-**
-** ^The third argument is the value to bind to the parameter.
-** ^If the third parameter to sqlite3_bind_text() or sqlite3_bind_text16()
-** or sqlite3_bind_blob() is a NULL pointer then the fourth parameter
-** is ignored and the end result is the same as sqlite3_bind_null().
-**
-** ^(In those routines that have a fourth argument, its value is the
-** number of bytes in the parameter.  To be clear: the value is the
-** number of <u>bytes</u> in the value, not the number of characters.)^
-** ^If the fourth parameter to sqlite3_bind_text() or sqlite3_bind_text16()
-** is negative, then the length of the string is
-** the number of bytes up to the first zero terminator.
-** If the fourth parameter to sqlite3_bind_blob() is negative, then
-** the behavior is undefined.
-** If a non-negative fourth parameter is provided to sqlite3_bind_text()
-** or sqlite3_bind_text16() or sqlite3_bind_text64() then
-** that parameter must be the byte offset
-** where the NUL terminator would occur assuming the string were NUL
-** terminated.  If any NUL characters occur at byte offsets less than 
-** the value of the fourth parameter then the resulting string value will
-** contain embedded NULs.  The result of expressions involving strings
-** with embedded NULs is undefined.
-**
-** ^The fifth argument to the BLOB and string binding interfaces
-** is a destructor used to dispose of the BLOB or
-** string after SQLite has finished with it.  ^The destructor is called
-** to dispose of the BLOB or string even if the call to bind API fails.
-** ^If the fifth argument is
-** the special value [SQLITE_STATIC], then SQLite assumes that the
-** information is in static, unmanaged space and does not need to be freed.
-** ^If the fifth argument has the value [SQLITE_TRANSIENT], then
-** SQLite makes its own private copy of the data immediately, before
-** the sqlite3_bind_*() routine returns.
-**
-** ^The sixth argument to sqlite3_bind_text64() must be one of
-** [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE]
-** to specify the encoding of the text in the third parameter.  If
-** the sixth argument to sqlite3_bind_text64() is not one of the
-** allowed values shown above, or if the text encoding is different
-** from the encoding specified by the sixth parameter, then the behavior
-** is undefined.
-**
-** ^The sqlite3_bind_zeroblob() routine binds a BLOB of length N that
-** is filled with zeroes.  ^A zeroblob uses a fixed amount of memory
-** (just an integer to hold its size) while it is being processed.
-** Zeroblobs are intended to serve as placeholders for BLOBs whose
-** content is later written using
-** [sqlite3_blob_open | incremental BLOB I/O] routines.
-** ^A negative value for the zeroblob results in a zero-length BLOB.
-**
-** ^The sqlite3_bind_pointer(S,I,P,T,D) routine causes the I-th parameter in
-** [prepared statement] S to have an SQL value of NULL, but to also be
-** associated with the pointer P of type T.  ^D is either a NULL pointer or
-** a pointer to a destructor function for P. ^SQLite will invoke the
-** destructor D with a single argument of P when it is finished using
-** P.  The T parameter should be a static string, preferably a string
-** literal. The sqlite3_bind_pointer() routine is part of the
-** [pointer passing interface] added for SQLite 3.20.0.

-** METHOD: sqlite3_stmt
-**
-** After a [prepared statement] has been prepared using any of
-** [sqlite3_prepare_v2()], [sqlite3_prepare_v3()], [sqlite3_prepare16_v2()],
-** or [sqlite3_prepare16_v3()] or one of the legacy
-** interfaces [sqlite3_prepare()] or [sqlite3_prepare16()], this function
-** must be called one or more times to evaluate the statement.
-**
-** The details of the behavior of the sqlite3_step() interface depend
-** on whether the statement was prepared using the newer "vX" interfaces
-** [sqlite3_prepare_v3()], [sqlite3_prepare_v2()], [sqlite3_prepare16_v3()],
-** [sqlite3_prepare16_v2()] or the older legacy
-** interfaces [sqlite3_prepare()] and [sqlite3_prepare16()].  The use of the
-** new "vX" interface is recommended for new applications but the legacy
-** interface will continue to be supported.
-**
-** ^In the legacy interface, the return value will be either [SQLITE_BUSY],
-** [SQLITE_DONE], [SQLITE_ROW], [SQLITE_ERROR], or [SQLITE_MISUSE].
-** ^With the "v2" interface, any of the other [result codes] or
-** [extended result codes] might be returned as well.
-**
-** ^[SQLITE_BUSY] means that the database engine was unable to acquire the
-** database locks it needs to do its job.  ^If the statement is a [COMMIT]
-** or occurs outside of an explicit transaction, then you can retry the
-** statement.  If the statement is not a [COMMIT] and occurs within an
-** explicit transaction then you should rollback the transaction before
-** continuing.
-**
-** ^[SQLITE_DONE] means that the statement has finished executing
-** successfully.  sqlite3_step() should not be called again on this virtual
-** machine without first calling [sqlite3_reset()] to reset the virtual
-** machine back to its initial state.
-**
-** ^If the SQL statement being executed returns any data, then [SQLITE_ROW]
-** is returned each time a new row of data is ready for processing by the
-** caller. The values may be accessed using the [column access functions].
-** sqlite3_step() is called again to retrieve the next row of data.
-**
-** ^[SQLITE_ERROR] means that a run-time error (such as a constraint
-** violation) has occurred.  sqlite3_step() should not be called again on
-** the VM. More information may be found by calling [sqlite3_errmsg()].
-** ^With the legacy interface, a more specific error code (for example,
-** [SQLITE_INTERRUPT], [SQLITE_SCHEMA], [SQLITE_CORRUPT], and so forth)
-** can be obtained by calling [sqlite3_reset()] on the
-** [prepared statement].  ^In the "v2" interface,
-** the more specific error code is returned directly by sqlite3_step().
-**
-** [SQLITE_MISUSE] means that the this routine was called inappropriately.
-** Perhaps it was called on a [prepared statement] that has
-** already been [sqlite3_finalize | finalized] or on one that had
-** previously returned [SQLITE_ERROR] or [SQLITE_DONE].  Or it could
-** be the case that the same database connection is being used by two or
-** more threads at the same moment in time.
-**
-** For all versions of SQLite up to and including 3.6.23.1, a call to
-** [sqlite3_reset()] was required after sqlite3_step() returned anything
-** other than [SQLITE_ROW] before any subsequent invocation of
-** sqlite3_step().  Failure to reset the prepared statement using 
-** [sqlite3_reset()] would result in an [SQLITE_MISUSE] return from
-** sqlite3_step().  But after [version 3.6.23.1] ([dateof:3.6.23.1],
-** sqlite3_step() began
-** calling [sqlite3_reset()] automatically in this circumstance rather
-** than returning [SQLITE_MISUSE].  This is not considered a compatibility
-** break because any application that ever receives an SQLITE_MISUSE error
-** is broken by definition.  The [SQLITE_OMIT_AUTORESET] compile-time option
-** can be used to restore the legacy behavior.
-**
-** <b>Goofy Interface Alert:</b> In the legacy interface, the sqlite3_step()
-** API always returns a generic error code, [SQLITE_ERROR], following any
-** error other than [SQLITE_BUSY] and [SQLITE_MISUSE].  You must call
-** [sqlite3_reset()] or [sqlite3_finalize()] in order to find one of the
-** specific [error codes] that better describes the error.
-** We admit that this is a goofy design.  The problem has been fixed
-** with the "v2" interface.  If you prepare all of your SQL statements
-** using [sqlite3_prepare_v3()] or [sqlite3_prepare_v2()]
-** or [sqlite3_prepare16_v2()] or [sqlite3_prepare16_v3()] instead
-** of the legacy [sqlite3_prepare()] and [sqlite3_prepare16()] interfaces,
-** then the more specific [error codes] are returned directly

-**
-** <b>Details:</b>
-**
-** ^These routines return information about a single column of the current
-** result row of a query.  ^In every case the first argument is a pointer
-** to the [prepared statement] that is being evaluated (the [sqlite3_stmt*]
-** that was returned from [sqlite3_prepare_v2()] or one of its variants)
-** and the second argument is the index of the column for which information
-** should be returned. ^The leftmost column of the result set has the index 0.
-** ^The number of columns in the result can be determined using
-** [sqlite3_column_count()].
-**
-** If the SQL statement does not currently point to a valid row, or if the
-** column index is out of range, the result is undefined.
-** These routines may only be called when the most recent call to
-** [sqlite3_step()] has returned [SQLITE_ROW] and neither
-** [sqlite3_reset()] nor [sqlite3_finalize()] have been called subsequently.
-** If any of these routines are called after [sqlite3_reset()] or
-** [sqlite3_finalize()] or after [sqlite3_step()] has returned
-** something other than [SQLITE_ROW], the results are undefined.
-** If [sqlite3_step()] or [sqlite3_reset()] or [sqlite3_finalize()]
-** are called from a different thread while any of these routines
-** are pending, then the results are undefined.
-**
-** The first six interfaces (_blob, _double, _int, _int64, _text, and _text16)
-** each return the value of a result column in a specific data format.  If
-** the result column is not initially in the requested format (for example,
-** if the query returns an integer but the sqlite3_column_text() interface
-** is used to extract the value) then an automatic type conversion is performed.
-**
-** ^The sqlite3_column_type() routine returns the
-** [SQLITE_INTEGER | datatype code] for the initial data type
-** of the result column.  ^The returned value is one of [SQLITE_INTEGER],
-** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].
-** The return value of sqlite3_column_type() can be used to decide which
-** of the first six interface should be used to extract the column value.
-** The value returned by sqlite3_column_type() is only meaningful if no
-** automatic type conversions have occurred for the value in question.  
-** After a type conversion, the result of calling sqlite3_column_type()
-** is undefined, though harmless.  Future
-** versions of SQLite may change the behavior of sqlite3_column_type()
-** following a type conversion.
-**
-** If the result is a BLOB or a TEXT string, then the sqlite3_column_bytes()
-** or sqlite3_column_bytes16() interfaces can be used to determine the size
-** of that BLOB or string.
-**
-** ^If the result is a BLOB or UTF-8 string then the sqlite3_column_bytes()
-** routine returns the number of bytes in that BLOB or string.
-** ^If the result is a UTF-16 string, then sqlite3_column_bytes() converts
-** the string to UTF-8 and then returns the number of bytes.
-** ^If the result is a numeric value then sqlite3_column_bytes() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-8 string and returns
-** the number of bytes in that string.
-** ^If the result is NULL, then sqlite3_column_bytes() returns zero.
-**
-** ^If the result is a BLOB or UTF-16 string then the sqlite3_column_bytes16()
-** routine returns the number of bytes in that BLOB or string.
-** ^If the result is a UTF-8 string, then sqlite3_column_bytes16() converts
-** the string to UTF-16 and then returns the number of bytes.
-** ^If the result is a numeric value then sqlite3_column_bytes16() uses
-** [sqlite3_snprintf()] to convert that value to a UTF-16 string and returns
-** the number of bytes in that string.
-** ^If the result is NULL, then sqlite3_column_bytes16() returns zero.
-**
-** ^The values returned by [sqlite3_column_bytes()] and 
-** [sqlite3_column_bytes16()] do not include the zero terminators at the end
-** of the string.  ^For clarity: the values returned by
-** [sqlite3_column_bytes()] and [sqlite3_column_bytes16()] are the number of
-** bytes in the string, not the number of characters.
-**
-** ^Strings returned by sqlite3_column_text() and sqlite3_column_text16(),
-** even empty strings, are always zero-terminated.  ^The return
-** value from sqlite3_column_blob() for a zero-length BLOB is a NULL pointer.
-**
-** <b>Warning:</b> ^The object returned by [sqlite3_column_value()] is an
-** [unprotected sqlite3_value] object.  In a multithreaded environment,
-** an unprotected sqlite3_value object may only be used safely with
-** [sqlite3_bind_value()] and [sqlite3_result_value()].
-** If the [unprotected sqlite3_value] object returned by
-** [sqlite3_column_value()] is used in any other way, including calls
-** to routines like [sqlite3_value_int()], [sqlite3_value_text()],
-** or [sqlite3_value_bytes()], the behavior is not threadsafe.
-** Hence, the sqlite3_column_value() interface
-** is normally only useful within the implementation of 
-** [application-defined SQL functions] or [virtual tables], not within
-** top-level application code.
-**
-** The these routines may attempt to convert the datatype of the result.
-** ^For example, if the internal representation is FLOAT and a text result
-** is requested, [sqlite3_snprintf()] is used internally to perform the
-** conversion automatically.  ^(The following table details the conversions
-** that are applied:
-**
-** <blockquote>
-** <table border="1">
-** <tr><th> Internal<br>Type <th> Requested<br>Type <th>  Conversion
-**
-** <tr><td>  NULL    <td> INTEGER   <td> Result is 0

-** <tr><td>  NULL    <td>   TEXT    <td> Result is a NULL pointer
-** <tr><td>  NULL    <td>   BLOB    <td> Result is a NULL pointer

-** <tr><td> INTEGER  <td>   TEXT    <td> ASCII rendering of the integer
-** <tr><td> INTEGER  <td>   BLOB    <td> Same as INTEGER->TEXT

-** <tr><td>  BLOB    <td>   TEXT    <td> Add a zero terminator if needed
-** </table>
-** </blockquote>)^
-**
-** Note that when type conversions occur, pointers returned by prior
-** calls to sqlite3_column_blob(), sqlite3_column_text(), and/or
-** sqlite3_column_text16() may be invalidated.
-** Type conversions and pointer invalidations might occur
-** in the following cases:
-**
-** <ul>
-** <li> The initial content is a BLOB and sqlite3_column_text() or
-**      sqlite3_column_text16() is called.  A zero-terminator might
-**      need to be added to the string.</li>
-** <li> The initial content is UTF-8 text and sqlite3_column_bytes16() or
-**      sqlite3_column_text16() is called.  The content must be converted
-**      to UTF-16.</li>
-** <li> The initial content is UTF-16 text and sqlite3_column_bytes() or
-**      sqlite3_column_text() is called.  The content must be converted
-**      to UTF-8.</li>
-** </ul>
-**
-** ^Conversions between UTF-16be and UTF-16le are always done in place and do
-** not invalidate a prior pointer, though of course the content of the buffer
-** that the prior pointer references will have been modified.  Other kinds
-** of conversion are done in place when it is possible, but sometimes they
-** are not possible and in those cases prior pointers are invalidated.
-**
-** The safest policy is to invoke these routines
-** in one of the following ways:
-**
-** <ul>
-**  <li>sqlite3_column_text() followed by sqlite3_column_bytes()</li>
-**  <li>sqlite3_column_blob() followed by sqlite3_column_bytes()</li>
-**  <li>sqlite3_column_text16() followed by sqlite3_column_bytes16()</li>
-** </ul>
-**
-** In other words, you should call sqlite3_column_text(),
-** sqlite3_column_blob(), or sqlite3_column_text16() first to force the result
-** into the desired format, then invoke sqlite3_column_bytes() or
-** sqlite3_column_bytes16() to find the size of the result.  Do not mix calls
-** to sqlite3_column_text() or sqlite3_column_blob() with calls to
-** sqlite3_column_bytes16(), and do not mix calls to sqlite3_column_text16()
-** with calls to sqlite3_column_bytes().
-**
-** ^The pointers returned are valid until a type conversion occurs as
-** described above, or until [sqlite3_step()] or [sqlite3_reset()] or
-** [sqlite3_finalize()] is called.  ^The memory space used to hold strings
-** and BLOBs is freed automatically.  Do not pass the pointers returned
-** from [sqlite3_column_blob()], [sqlite3_column_text()], etc. into
-** [sqlite3_free()].
-**
-** ^(If a memory allocation error occurs during the evaluation of any
-** of these routines, a default value is returned.  The default value
-** is either the integer 0, the floating point number 0.0, or a NULL
-** pointer.  Subsequent calls to [sqlite3_errcode()] will return
-** [SQLITE_NOMEM].)^

-** METHOD: sqlite3
-**
-** ^These functions (collectively known as "function creation routines")
-** are used to add SQL functions or aggregates or to redefine the behavior
-** of existing SQL functions or aggregates.  The only differences between
-** these routines are the text encoding expected for
-** the second parameter (the name of the function being created)
-** and the presence or absence of a destructor callback for
-** the application data pointer.
-**
-** ^The first parameter is the [database connection] to which the SQL
-** function is to be added.  ^If an application uses more than one database
-** connection then application-defined SQL functions must be added
-** to each database connection separately.
-**
-** ^The second parameter is the name of the SQL function to be created or
-** redefined.  ^The length of the name is limited to 255 bytes in a UTF-8
-** representation, exclusive of the zero-terminator.  ^Note that the name
-** length limit is in UTF-8 bytes, not characters nor UTF-16 bytes.  
-** ^Any attempt to create a function with a longer name
-** will result in [SQLITE_MISUSE] being returned.
-**
-** ^The third parameter (nArg)
-** is the number of arguments that the SQL function or
-** aggregate takes. ^If this parameter is -1, then the SQL function or
-** aggregate may take any number of arguments between 0 and the limit
-** set by [sqlite3_limit]([SQLITE_LIMIT_FUNCTION_ARG]).  If the third
-** parameter is less than -1 or greater than 127 then the behavior is
-** undefined.
-**
-** ^The fourth parameter, eTextRep, specifies what
-** [SQLITE_UTF8 | text encoding] this SQL function prefers for
-** its parameters.  The application should set this parameter to
-** [SQLITE_UTF16LE] if the function implementation invokes 
-** [sqlite3_value_text16le()] on an input, or [SQLITE_UTF16BE] if the
-** implementation invokes [sqlite3_value_text16be()] on an input, or
-** [SQLITE_UTF16] if [sqlite3_value_text16()] is used, or [SQLITE_UTF8]
-** otherwise.  ^The same SQL function may be registered multiple times using
-** different preferred text encodings, with different implementations for
-** each encoding.
-** ^When multiple implementations of the same function are available, SQLite
-** will pick the one that involves the least amount of data conversion.
-**
-** ^The fourth parameter may optionally be ORed with [SQLITE_DETERMINISTIC]
-** to signal that the function will always return the same result given
-** the same inputs within a single SQL statement.  Most SQL functions are
-** deterministic.  The built-in [random()] SQL function is an example of a
-** function that is not deterministic.  The SQLite query planner is able to
-** perform additional optimizations on deterministic functions, so use
-** of the [SQLITE_DETERMINISTIC] flag is recommended where possible.
-**
-** ^(The fifth parameter is an arbitrary pointer.  The implementation of the
-** function can gain access to this pointer using [sqlite3_user_data()].)^
-**
-** ^The sixth, seventh and eighth parameters, xFunc, xStep and xFinal, are
-** pointers to C-language functions that implement the SQL function or
-** aggregate. ^A scalar SQL function requires an implementation of the xFunc
-** callback only; NULL pointers must be passed as the xStep and xFinal
-** parameters. ^An aggregate SQL function requires an implementation of xStep
-** and xFinal and NULL pointer must be passed for xFunc. ^To delete an existing
-** SQL function or aggregate, pass NULL pointers for all three function
-** callbacks.
-**
-** ^(If the ninth parameter to sqlite3_create_function_v2() is not NULL,
-** then it is destructor for the application data pointer. 
-** The destructor is invoked when the function is deleted, either by being
-** overloaded or when the database connection closes.)^
-** ^The destructor is also invoked if the call to
-** sqlite3_create_function_v2() fails.
-** ^When the destructor callback of the tenth parameter is invoked, it
-** is passed a single argument which is a copy of the application data 
-** pointer which was the fifth parameter to sqlite3_create_function_v2().
-**
-** ^It is permitted to register multiple implementations of the same
-** functions with the same name but with either differing numbers of
-** arguments or differing preferred text encodings.  ^SQLite will use
-** the implementation that most closely matches the way in which the
-** SQL function is used.  ^A function implementation with a non-negative
-** nArg parameter is a better match than a function implementation with
-** a negative nArg.  ^A function where the preferred text encoding
-** matches the database encoding is a better
-** match than a function where the encoding is different.  
-** ^A function where the encoding difference is between UTF16le and UTF16be
-** is a closer match than a function where the encoding difference is
-** between UTF8 and UTF16.
-**
-** ^Built-in functions may be overloaded by new application-defined functions.
-**
-** ^An application-defined function is permitted to call other
-** SQLite interfaces.  However, such calls must not
-** close the database connection nor finalize or reset the prepared

-**
-** <b>Details:</b>
-**
-** These routines extract type, size, and content information from
-** [protected sqlite3_value] objects.  Protected sqlite3_value objects
-** are used to pass parameter information into implementation of
-** [application-defined SQL functions] and [virtual tables].
-**
-** These routines work only with [protected sqlite3_value] objects.
-** Any attempt to use these routines on an [unprotected sqlite3_value]
-** is not threadsafe.
-**
-** ^These routines work just like the corresponding [column access functions]
-** except that these routines take a single [protected sqlite3_value] object
-** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
-**
-** ^The sqlite3_value_text16() interface extracts a UTF-16 string
-** in the native byte-order of the host machine.  ^The
-** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
-** extract UTF-16 strings as big-endian and little-endian respectively.
-**
-** ^If [sqlite3_value] object V was initialized 
-** using [sqlite3_bind_pointer(S,I,P,X,D)] or [sqlite3_result_pointer(C,P,X,D)]
-** and if X and Y are strings that compare equal according to strcmp(X,Y),
-** then sqlite3_value_pointer(V,Y) will return the pointer P.  ^Otherwise,
-** sqlite3_value_pointer(V,Y) returns a NULL. The sqlite3_bind_pointer() 
-** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
-**
-** ^(The sqlite3_value_type(V) interface returns the
-** [SQLITE_INTEGER | datatype code] for the initial datatype of the
-** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER],
-** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^
-** Other interfaces might change the datatype for an sqlite3_value object.
-** For example, if the datatype is initially SQLITE_INTEGER and
-** sqlite3_value_text(V) is called to extract a text value for that
-** integer, then subsequent calls to sqlite3_value_type(V) might return
-** SQLITE_TEXT.  Whether or not a persistent internal datatype conversion
-** occurs is undefined and may change from one release of SQLite to the next.
-**
-** ^(The sqlite3_value_numeric_type() interface attempts to apply
-** numeric affinity to the value.  This means that an attempt is
-** made to convert the value to an integer or floating point.  If
-** such a conversion is possible without loss of information (in other
-** words, if the value is a string that looks like a number)
-** then the conversion is performed.  Otherwise no conversion occurs.
-** The [SQLITE_INTEGER | datatype] after conversion is returned.)^
-**
-** ^Within the [xUpdate] method of a [virtual table], the
-** sqlite3_value_nochange(X) interface returns true if and only if
-** the column corresponding to X is unchanged by the UPDATE operation
-** that the xUpdate method call was invoked to implement and if
-** and the prior [xColumn] method call that was invoked to extracted
-** the value for that column returned without setting a result (probably
-** because it queried [sqlite3_vtab_nochange()] and found that the column
-** was unchanging).  ^Within an [xUpdate] method, any value for which
-** sqlite3_value_nochange(X) is true will in all other respects appear
-** to be a NULL value.  If sqlite3_value_nochange(X) is invoked anywhere other
-** than within an [xUpdate] method call for an UPDATE statement, then
-** the return value is arbitrary and meaningless.
-**
-** Please pay particular attention to the fact that the pointer returned
-** from [sqlite3_value_blob()], [sqlite3_value_text()], or
-** [sqlite3_value_text16()] can be invalidated by a subsequent call to
-** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
-** or [sqlite3_value_text16()].
-**
-** These routines must be called from the same thread as
-** the SQL function that supplied the [sqlite3_value*] parameters.

-** implementation is never called and xFinal() is called exactly once.
-** In those cases, sqlite3_aggregate_context() might be called for the

-**
-** ^The sqlite3_aggregate_context(C,N) routine returns a NULL pointer

-** ^The sqlite3_get_auxdata(C,N) interface returns a pointer to the metadata

-** ^After each call to sqlite3_set_auxdata(C,N,P,X) where X is not NULL,
-** SQLite will invoke the destructor function X with parameter P exactly
-** once, when the metadata is discarded.
-** SQLite is free to discard the metadata at any time, including: <ul>
-** <li> ^(when the corresponding function parameter changes)^, or
-** <li> ^(when [sqlite3_reset()] or [sqlite3_finalize()] is called for the

-**
-** These routines are used by the xFunc or xFinal callbacks that
-** implement SQL functions and aggregates.  See
-** [sqlite3_create_function()] and [sqlite3_create_function16()]
-** for additional information.
-**
-** These functions work very much like the [parameter binding] family of
-** functions used to bind values to host parameters in prepared statements.
-** Refer to the [SQL parameter] documentation for additional information.
-**
-** ^The sqlite3_result_blob() interface sets the result from
-** an application-defined function to be the BLOB whose content is pointed
-** to by the second parameter and which is N bytes long where N is the
-** third parameter.
-**
-** ^The sqlite3_result_zeroblob(C,N) and sqlite3_result_zeroblob64(C,N)
-** interfaces set the result of the application-defined function to be
-** a BLOB containing all zero bytes and N bytes in size.
-**
-** ^The sqlite3_result_double() interface sets the result from
-** an application-defined function to be a floating point value specified
-** by its 2nd argument.
-**
-** ^The sqlite3_result_error() and sqlite3_result_error16() functions
-** cause the implemented SQL function to throw an exception.
-** ^SQLite uses the string pointed to by the
-** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
-** as the text of an error message.  ^SQLite interprets the error
-** message string from sqlite3_result_error() as UTF-8. ^SQLite
-** interprets the string from sqlite3_result_error16() as UTF-16 in native
-** byte order.  ^If the third parameter to sqlite3_result_error()
-** or sqlite3_result_error16() is negative then SQLite takes as the error
-** message all text up through the first zero character.
-** ^If the third parameter to sqlite3_result_error() or
-** sqlite3_result_error16() is non-negative then SQLite takes that many
-** bytes (not characters) from the 2nd parameter as the error message.
-** ^The sqlite3_result_error() and sqlite3_result_error16()
-** routines make a private copy of the error message text before
-** they return.  Hence, the calling function can deallocate or
-** modify the text after they return without harm.
-** ^The sqlite3_result_error_code() function changes the error code
-** returned by SQLite as a result of an error in a function.  ^By default,
-** the error code is SQLITE_ERROR.  ^A subsequent call to sqlite3_result_error()
-** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
-**
-** ^The sqlite3_result_error_toobig() interface causes SQLite to throw an
-** error indicating that a string or BLOB is too long to represent.
-**
-** ^The sqlite3_result_error_nomem() interface causes SQLite to throw an
-** error indicating that a memory allocation failed.
-**
-** ^The sqlite3_result_int() interface sets the return value
-** of the application-defined function to be the 32-bit signed integer
-** value given in the 2nd argument.
-** ^The sqlite3_result_int64() interface sets the return value
-** of the application-defined function to be the 64-bit signed integer
-** value given in the 2nd argument.
-**
-** ^The sqlite3_result_null() interface sets the return value
-** of the application-defined function to be NULL.
-**
-** ^The sqlite3_result_text(), sqlite3_result_text16(),
-** sqlite3_result_text16le(), and sqlite3_result_text16be() interfaces
-** set the return value of the application-defined function to be
-** a text string which is represented as UTF-8, UTF-16 native byte order,
-** UTF-16 little endian, or UTF-16 big endian, respectively.
-** ^The sqlite3_result_text64() interface sets the return value of an
-** application-defined function to be a text string in an encoding
-** specified by the fifth (and last) parameter, which must be one
-** of [SQLITE_UTF8], [SQLITE_UTF16], [SQLITE_UTF16BE], or [SQLITE_UTF16LE].
-** ^SQLite takes the text result from the application from
-** the 2nd parameter of the sqlite3_result_text* interfaces.
-** ^If the 3rd parameter to the sqlite3_result_text* interfaces
-** is negative, then SQLite takes result text from the 2nd parameter
-** through the first zero character.
-** ^If the 3rd parameter to the sqlite3_result_text* interfaces
-** is non-negative, then as many bytes (not characters) of the text
-** pointed to by the 2nd parameter are taken as the application-defined
-** function result.  If the 3rd parameter is non-negative, then it
-** must be the byte offset into the string where the NUL terminator would
-** appear if the string where NUL terminated.  If any NUL characters occur
-** in the string at a byte offset that is less than the value of the 3rd
-** parameter, then the resulting string will contain embedded NULs and the
-** result of expressions operating on strings with embedded NULs is undefined.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is a non-NULL pointer, then SQLite calls that
-** function as the destructor on the text or BLOB result when it has
-** finished using that result.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces or to
-** sqlite3_result_blob is the special constant SQLITE_STATIC, then SQLite
-** assumes that the text or BLOB result is in constant space and does not
-** copy the content of the parameter nor call a destructor on the content
-** when it has finished using that result.
-** ^If the 4th parameter to the sqlite3_result_text* interfaces
-** or sqlite3_result_blob is the special constant SQLITE_TRANSIENT
-** then SQLite makes a copy of the result into space obtained
-** from [sqlite3_malloc()] before it returns.
-**
-** ^The sqlite3_result_value() interface sets the result of
-** the application-defined function to be a copy of the
-** [unprotected sqlite3_value] object specified by the 2nd parameter.  ^The
-** sqlite3_result_value() interface makes a copy of the [sqlite3_value]
-** so that the [sqlite3_value] specified in the parameter may change or
-** be deallocated after sqlite3_result_value() returns without harm.
-** ^A [protected sqlite3_value] object may always be used where an
-** [unprotected sqlite3_value] object is required, so either
-** kind of [sqlite3_value] object can be used with this interface.
-**
-** ^The sqlite3_result_pointer(C,P,T,D) interface sets the result to an
-** SQL NULL value, just like [sqlite3_result_null(C)], except that it
-** also associates the host-language pointer P or type T with that 
-** NULL value such that the pointer can be retrieved within an
-** [application-defined SQL function] using [sqlite3_value_pointer()].
-** ^If the D parameter is not NULL, then it is a pointer to a destructor
-** for the P parameter.  ^SQLite invokes D with P as its only argument
-** when SQLite is finished with P.  The T parameter should be a static
-** string and preferably a string literal. The sqlite3_result_pointer()
-** routine is part of the [pointer passing interface] added for SQLite 3.20.0.
-**
-** If these routines are called from within the different thread
-** than the one containing the application-defined function that received

-** CAPI3REF: Define New Collating Sequences
-** METHOD: sqlite3
-**
-** ^These functions add, remove, or modify a [collation] associated
-** with the [database connection] specified as the first argument.
-**
-** ^The name of the collation is a UTF-8 string
-** for sqlite3_create_collation() and sqlite3_create_collation_v2()
-** and a UTF-16 string in native byte order for sqlite3_create_collation16().
-** ^Collation names that compare equal according to [sqlite3_strnicmp()] are
-** considered to be the same name.
-**
-** ^(The third argument (eTextRep) must be one of the constants:
-** <ul>
-** <li> [SQLITE_UTF8],
-** <li> [SQLITE_UTF16LE],
-** <li> [SQLITE_UTF16BE],
-** <li> [SQLITE_UTF16], or
-** <li> [SQLITE_UTF16_ALIGNED].
-** </ul>)^
-** ^The eTextRep argument determines the encoding of strings passed
-** to the collating function callback, xCallback.
-** ^The [SQLITE_UTF16] and [SQLITE_UTF16_ALIGNED] values for eTextRep
-** force strings to be UTF16 with native byte order.
-** ^The [SQLITE_UTF16_ALIGNED] value for eTextRep forces strings to begin
-** on an even byte address.
-**
-** ^The fourth argument, pArg, is an application data pointer that is passed
-** through as the first argument to the collating function callback.
-**
-** ^The fifth argument, xCallback, is a pointer to the collating function.
-** ^Multiple collating functions can be registered using the same name but
-** with different eTextRep parameters and SQLite will use whichever
-** function requires the least amount of data transformation.
-** ^If the xCallback argument is NULL then the collating function is
-** deleted.  ^When all collating functions having the same name are deleted,
-** that collation is no longer usable.
-**
-** ^The collating function callback is invoked with a copy of the pArg 
-** application data pointer and with two strings in the encoding specified
-** by the eTextRep argument.  The collating function must return an
-** integer that is negative, zero, or positive
-** if the first string is less than, equal to, or greater than the second,
-** respectively.  A collating function must always return the same answer
-** given the same inputs.  If two or more collating functions are registered
-** to the same collation name (using different eTextRep values) then all
-** must give an equivalent answer when invoked with equivalent strings.
-** The collating function must obey the following properties for all
-** strings A, B, and C:
-**
-** <ol>
-** <li> If A==B then B==A.
-** <li> If A==B and B==C then A==C.
-** <li> If A&lt;B THEN B&gt;A.
-** <li> If A&lt;B and B&lt;C then A&lt;C.
-** </ol>
-**
-** If a collating function fails any of the above constraints and that
-** collating function is  registered and used, then the behavior of SQLite
-** is undefined.
-**
-** ^The sqlite3_create_collation_v2() works like sqlite3_create_collation()
-** with the addition that the xDestroy callback is invoked on pArg when
-** the collating function is deleted.
-** ^Collating functions are deleted when they are overridden by later
-** calls to the collation creation functions or when the
-** [database connection] is closed using [sqlite3_close()].
-**
-** ^The xDestroy callback is <u>not</u> called if the 
-** sqlite3_create_collation_v2() function fails.  Applications that invoke
-** sqlite3_create_collation_v2() with a non-NULL xDestroy argument should 
-** check the return code and dispose of the application data pointer
-** themselves rather than expecting SQLite to deal with it for them.
-** This is different from every other SQLite interface.  The inconsistency 
-** is unfortunate but cannot be changed without breaking backwards 
-** compatibility.

-** CAPI3REF: Impose A Limit On Heap Size
-**
-** ^The sqlite3_soft_heap_limit64() interface sets and/or queries the
-** soft limit on the amount of heap memory that may be allocated by SQLite.
-** ^SQLite strives to keep heap memory utilization below the soft heap
-** limit by reducing the number of pages held in the page cache
-** as heap memory usages approaches the limit.
-** ^The soft heap limit is "soft" because even though SQLite strives to stay
-** below the limit, it will exceed the limit rather than generate
-** an [SQLITE_NOMEM] error.  In other words, the soft heap limit 
-** is advisory only.
-**
-** ^The return value from sqlite3_soft_heap_limit64() is the size of
-** the soft heap limit prior to the call, or negative in the case of an
-** error.  ^If the argument N is negative
-** then no change is made to the soft heap limit.  Hence, the current
-** size of the soft heap limit can be determined by invoking
-** sqlite3_soft_heap_limit64() with a negative argument.
-**
-** ^If the argument N is zero then the soft heap limit is disabled.
-**
-** ^(The soft heap limit is not enforced in the current implementation
-** if one or more of following conditions are true:
-**
-** <ul>
-** <li> The soft heap limit is set to zero.
-** <li> Memory accounting is disabled using a combination of the
-**      [sqlite3_config]([SQLITE_CONFIG_MEMSTATUS],...) start-time option and
-**      the [SQLITE_DEFAULT_MEMSTATUS] compile-time option.
-** <li> An alternative page cache implementation is specified using
-**      [sqlite3_config]([SQLITE_CONFIG_PCACHE2],...).
-** <li> The page cache allocates from its own memory pool supplied
-**      by [sqlite3_config]([SQLITE_CONFIG_PAGECACHE],...) rather than
-**      from the heap.
-** </ul>)^
-**
-** Beginning with SQLite [version 3.7.3] ([dateof:3.7.3]), 
-** the soft heap limit is enforced
-** regardless of whether or not the [SQLITE_ENABLE_MEMORY_MANAGEMENT]
-** compile-time option is invoked.  With [SQLITE_ENABLE_MEMORY_MANAGEMENT],
-** the soft heap limit is enforced on every memory allocation.  Without
-** [SQLITE_ENABLE_MEMORY_MANAGEMENT], the soft heap limit is only enforced
-** when memory is allocated by the page cache.  Testing suggests that because
-** the page cache is the predominate memory user in SQLite, most
-** applications will achieve adequate soft heap limit enforcement without
-** the use of [SQLITE_ENABLE_MEMORY_MANAGEMENT].
-**
-** The circumstances under which SQLite will enforce the soft heap limit may
-** changes in future releases of SQLite.

-** The sqlite3_index_info structure and its substructures is used as part
-** of the [virtual table] interface to
-** pass information into and receive the reply from the [xBestIndex]
-** method of a [virtual table module].  The fields under **Inputs** are the
-** inputs to xBestIndex and are read-only.  xBestIndex inserts its
-** results into the **Outputs** fields.
-**
-** ^(The aConstraint[] array records WHERE clause constraints of the form:
-**
-** <blockquote>column OP expr</blockquote>
-**
-** where OP is =, &lt;, &lt;=, &gt;, or &gt;=.)^  ^(The particular operator is
-** stored in aConstraint[].op using one of the
-** [SQLITE_INDEX_CONSTRAINT_EQ | SQLITE_INDEX_CONSTRAINT_ values].)^
-** ^(The index of the column is stored in
-** aConstraint[].iColumn.)^  ^(aConstraint[].usable is TRUE if the
-** expr on the right-hand side can be evaluated (and thus the constraint
-** is usable) and false if it cannot.)^
-**
-** ^The optimizer automatically inverts terms of the form "expr OP column"
-** and makes other simplifications to the WHERE clause in an attempt to
-** get as many WHERE clause terms into the form shown above as possible.
-** ^The aConstraint[] array only reports WHERE clause terms that are
-** relevant to the particular virtual table being queried.
-**
-** ^Information about the ORDER BY clause is stored in aOrderBy[].
-** ^Each term of aOrderBy records a column of the ORDER BY clause.
-**
-** The colUsed field indicates which columns of the virtual table may be
-** required by the current scan. Virtual table columns are numbered from
-** zero in the order in which they appear within the CREATE TABLE statement
-** passed to sqlite3_declare_vtab(). For the first 63 columns (columns 0-62),
-** the corresponding bit is set within the colUsed mask if the column may be
-** required by SQLite. If the table has at least 64 columns and any column
-** to the right of the first 63 is required, then bit 63 of colUsed is also
-** set. In other words, column iCol may be required if the expression
-** (colUsed & ((sqlite3_uint64)1 << (iCol>=63 ? 63 : iCol))) evaluates to 
-** non-zero.
-**
-** The [xBestIndex] method must fill aConstraintUsage[] with information
-** about what parameters to pass to xFilter.  ^If argvIndex>0 then
-** the right-hand side of the corresponding aConstraint[] is evaluated
-** and becomes the argvIndex-th entry in argv.  ^(If aConstraintUsage[].omit
-** is true, then the constraint is assumed to be fully handled by the
-** virtual table and is not checked again by SQLite.)^
-**
-** ^The idxNum and idxPtr values are recorded and passed into the
-** [xFilter] method.
-** ^[sqlite3_free()] is used to free idxPtr if and only if
-** needToFreeIdxPtr is true.
-**
-** ^The orderByConsumed means that output from [xFilter]/[xNext] will occur in
-** the correct order to satisfy the ORDER BY clause so that no separate
-** sorting step is required.
-**
-** ^The estimatedCost value is an estimate of the cost of a particular
-** strategy. A cost of N indicates that the cost of the strategy is similar
-** to a linear scan of an SQLite table with N rows. A cost of log(N) 
-** indicates that the expense of the operation is similar to that of a
-** binary search on a unique indexed field of an SQLite table with N rows.
-**
-** ^The estimatedRows value is an estimate of the number of rows that
-** will be returned by the strategy.
-**
-** The xBestIndex method may optionally populate the idxFlags field with a 
-** mask of SQLITE_INDEX_SCAN_* flags. Currently there is only one such flag -
-** SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
-** assumes that the strategy may visit at most one row. 
-**
-** Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
-** SQLite also assumes that if a call to the xUpdate() method is made as
-** part of the same statement to delete or update a virtual table row and the
-** implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
-** any database changes. In other words, if the xUpdate() returns
-** SQLITE_CONSTRAINT, the database contents must be exactly as they were
-** before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
-** set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
-** the xUpdate method are automatically rolled back by SQLite.
-**
-** IMPORTANT: The estimatedRows field was added to the sqlite3_index_info
-** structure for SQLite [version 3.8.2] ([dateof:3.8.2]). 
-** If a virtual table extension is
-** used with an SQLite version earlier than 3.8.2, the results of attempting 
-** to read or write the estimatedRows field are undefined (but are likely 
-** to included crashing the application). The estimatedRows field should
-** therefore only be used if [sqlite3_libversion_number()] returns a
-** value greater than or equal to 3008002. Similarly, the idxFlags field
-** was added for [version 3.9.0] ([dateof:3.9.0]).

-** Usually, the default mutex implementations provided by SQLite are
-** sufficient, however the application has the option of substituting a custom
-** implementation for specialized deployments or systems for which SQLite
-** does not provide a suitable implementation. In this case, the application
-** creates and populates an instance of this structure to pass

-** Additionally, an instance of this structure can be used as an
-** output variable when querying the system for the current mutex
-** implementation, using the [SQLITE_CONFIG_GETMUTEX] option.
-**
-** ^The xMutexInit method defined by this structure is invoked as
-** part of system initialization by the sqlite3_initialize() function.
-** ^The xMutexInit routine is called by SQLite exactly once for each
-** effective call to [sqlite3_initialize()].
-**
-** ^The xMutexEnd method defined by this structure is invoked as
-** part of system shutdown by the sqlite3_shutdown() function. The
-** implementation of this method is expected to release all outstanding
-** resources obtained by the mutex methods implementation, especially
-** those obtained by the xMutexInit method.  ^The xMutexEnd()
-** interface is invoked exactly once for each call to [sqlite3_shutdown()].
-**
-** ^(The remaining seven methods defined by this structure (xMutexAlloc,
-** xMutexFree, xMutexEnter, xMutexTry, xMutexLeave, xMutexHeld and
-** xMutexNotheld) implement the following interfaces (respectively):
-**
-** <ul>
-**   <li>  [sqlite3_mutex_alloc()] </li>

-**
-** The only difference is that the public sqlite3_XXX functions enumerated

-** of a valid mutex handle. The implementations of the methods defined
-** by this structure are not required to handle this case, the results

-** (i.e. it is acceptable to provide an implementation that segfaults if

-** are intended for use inside assert() statements.  The SQLite core
-** never uses these routines except inside an assert() and applications
-** are advised to follow the lead of the core.  The SQLite core only

-** with the SQLITE_DEBUG flag.  External mutex implementations
-** are only required to provide these routines if SQLITE_DEBUG is
-** defined and if NDEBUG is not defined.
-**
-** These routines should return true if the mutex in their argument
-** is held or not held, respectively, by the calling thread.
-**
-** The implementation is not required to provide versions of these
-** routines that actually work. If the implementation does not provide working
-** versions of these routines, it should at least provide stubs that always
-** return true so that one does not get spurious assertion failures.
-**
-** If the argument to sqlite3_mutex_held() is a NULL pointer then
-** the routine should return 1.   This seems counter-intuitive since
-** clearly the mutex cannot be held if it does not exist.  But
-** the reason the mutex does not exist is because the build is not
-** using mutexes.  And we do not want the assert() containing the
-** call to sqlite3_mutex_held() to fail, so a non-zero return is

-** CAPI3REF: SQL Keyword Checking
-**
-** These routines provide access to the set of SQL language keywords 
-** recognized by SQLite.  Applications can uses these routines to determine
-** whether or not a specific identifier needs to be escaped (for example,
-** by enclosing in double-quotes) so as not to confuse the parser.
-**
-** The sqlite3_keyword_count() interface returns the number of distinct
-** keywords understood by SQLite.
-**
-** The sqlite3_keyword_name(N,Z,L) interface finds the N-th keyword and
-** makes *Z point to that keyword expressed as UTF8 and writes the number
-** of bytes in the keyword into *L.  The string that *Z points to is not
-** zero-terminated.  The sqlite3_keyword_name(N,Z,L) routine returns
-** SQLITE_OK if N is within bounds and SQLITE_ERROR if not. If either Z
-** or L are NULL or invalid pointers then calls to
-** sqlite3_keyword_name(N,Z,L) result in undefined behavior.
-**
-** The sqlite3_keyword_check(Z,L) interface checks to see whether or not
-** the L-byte UTF8 identifier that Z points to is a keyword, returning non-zero
-** if it is and zero if not.
-**
-** The parser used by SQLite is forgiving.  It is often possible to use
-** a keyword as an identifier as long as such use does not result in a
-** parsing ambiguity.  For example, the statement
-** "CREATE TABLE BEGIN(REPLACE,PRAGMA,END);" is accepted by SQLite, and
-** creates a new table named "BEGIN" with three columns named
-** "REPLACE", "PRAGMA", and "END".  Nevertheless, best practice is to avoid
-** using keywords as identifiers.  Common techniques used to avoid keyword
-** name collisions include:
-** <ul>
-** <li> Put all identifier names inside double-quotes.  This is the official
-**      SQL way to escape identifier names.
-** <li> Put identifier names inside &#91;...&#93;.  This is not standard SQL,
-**      but it is what SQL Server does and so lots of programmers use this
-**      technique.
-** <li> Begin every identifier with the letter "Z" as no SQL keywords start
-**      with "Z".
-** <li> Include a digit somewhere in every identifier name.
-** </ul>
-**
-** Note that the number of keywords understood by SQLite can depend on
-** compile-time options.  For example, "VACUUM" is not a keyword if
-** SQLite is compiled with the [-DSQLITE_OMIT_VACUUM] option.  Also,
-** new keywords may be added to future releases of SQLite.

-** CAPI3REF: Application Defined Page Cache.
-** KEYWORDS: {page cache}
-**
-** ^(The [sqlite3_config]([SQLITE_CONFIG_PCACHE2], ...) interface can
-** register an alternative page cache implementation by passing in an 
-** instance of the sqlite3_pcache_methods2 structure.)^
-** In many applications, most of the heap memory allocated by 
-** SQLite is used for the page cache.
-** By implementing a 
-** custom page cache using this API, an application can better control
-** the amount of memory consumed by SQLite, the way in which 
-** that memory is allocated and released, and the policies used to 
-** determine exactly which parts of a database file are cached and for 
-** how long.
-**
-** The alternative page cache mechanism is an
-** extreme measure that is only needed by the most demanding applications.
-** The built-in page cache is recommended for most uses.
-**
-** ^(The contents of the sqlite3_pcache_methods2 structure are copied to an
-** internal buffer by SQLite within the call to [sqlite3_config].  Hence
-** the application may discard the parameter after the call to
-** [sqlite3_config()] returns.)^
-**
-** [[the xInit() page cache method]]
-** ^(The xInit() method is called once for each effective 
-** call to [sqlite3_initialize()])^
-** (usually only once during the lifetime of the process). ^(The xInit()
-** method is passed a copy of the sqlite3_pcache_methods2.pArg value.)^
-** The intent of the xInit() method is to set up global data structures 
-** required by the custom page cache implementation. 
-** ^(If the xInit() method is NULL, then the 
-** built-in default page cache is used instead of the application defined
-** page cache.)^
-**
-** [[the xShutdown() page cache method]]
-** ^The xShutdown() method is called by [sqlite3_shutdown()].
-** It can be used to clean up 
-** any outstanding resources before process shutdown, if required.
-** ^The xShutdown() method may be NULL.
-**
-** ^SQLite automatically serializes calls to the xInit method,
-** so the xInit method need not be threadsafe.  ^The
-** xShutdown method is only called from [sqlite3_shutdown()] so it does
-** not need to be threadsafe either.  All other methods must be threadsafe
-** in multithreaded applications.
-**
-** ^SQLite will never invoke xInit() more than once without an intervening
-** call to xShutdown().
-**
-** [[the xCreate() page cache methods]]
-** ^SQLite invokes the xCreate() method to construct a new cache instance.
-** SQLite will typically create one cache instance for each open database file,
-** though this is not guaranteed. ^The
-** first parameter, szPage, is the size in bytes of the pages that must
-** be allocated by the cache.  ^szPage will always a power of two.  ^The
-** second parameter szExtra is a number of bytes of extra storage 
-** associated with each page cache entry.  ^The szExtra parameter will
-** a number less than 250.  SQLite will use the
-** extra szExtra bytes on each page to store metadata about the underlying
-** database page on disk.  The value passed into szExtra depends
-** on the SQLite version, the target platform, and how SQLite was compiled.
-** ^The third argument to xCreate(), bPurgeable, is true if the cache being
-** created will be used to cache database pages of a file stored on disk, or
-** false if it is used for an in-memory database. The cache implementation
-** does not have to do anything special based with the value of bPurgeable;
-** it is purely advisory.  ^On a cache where bPurgeable is false, SQLite will
-** never invoke xUnpin() except to deliberately delete a page.
-** ^In other words, calls to xUnpin() on a cache with bPurgeable set to
-** false will always have the "discard" flag set to true.  
-** ^Hence, a cache created with bPurgeable false will
-** never contain any unpinned pages.
-**
-** [[the xCachesize() page cache method]]
-** ^(The xCachesize() method may be called at any time by SQLite to set the
-** suggested maximum cache-size (number of pages stored by) the cache
-** instance passed as the first argument. This is the value configured using
-** the SQLite "[PRAGMA cache_size]" command.)^  As with the bPurgeable
-** parameter, the implementation is not required to do anything with this
-** value; it is advisory only.
-**
-** [[the xPagecount() page cache methods]]
-** The xPagecount() method must return the number of pages currently
-** stored in the cache, both pinned and unpinned.
-** 
-** [[the xFetch() page cache methods]]
-** The xFetch() method locates a page in the cache and returns a pointer to 
-** an sqlite3_pcache_page object associated with that page, or a NULL pointer.
-** The pBuf element of the returned sqlite3_pcache_page object will be a
-** pointer to a buffer of szPage bytes used to store the content of a 
-** single database page.  The pExtra element of sqlite3_pcache_page will be
-** a pointer to the szExtra bytes of extra storage that SQLite has requested
-** for each entry in the page cache.
-**
-** The page to be fetched is determined by the key. ^The minimum key value
-** is 1.  After it has been retrieved using xFetch, the page is considered
-** to be "pinned".
-**
-** If the requested page is already in the page cache, then the page cache
-** implementation must return a pointer to the page buffer with its content
-** intact.  If the requested page is not already in the cache, then the
-** cache implementation should use the value of the createFlag
-** parameter to help it determined what action to take:
-**
-** <table border=1 width=85% align=center>
-** <tr><th> createFlag <th> Behavior when page is not already in cache
-** <tr><td> 0 <td> Do not allocate a new page.  Return NULL.
-** <tr><td> 1 <td> Allocate a new page if it easy and convenient to do so.
-**                 Otherwise return NULL.
-** <tr><td> 2 <td> Make every effort to allocate a new page.  Only return
-**                 NULL if allocating a new page is effectively impossible.
-** </table>
-**
-** ^(SQLite will normally invoke xFetch() with a createFlag of 0 or 1.  SQLite
-** will only use a createFlag of 2 after a prior call with a createFlag of 1
-** failed.)^  In between the to xFetch() calls, SQLite may
-** attempt to unpin one or more cache pages by spilling the content of
-** pinned pages to disk and synching the operating system disk cache.
-**
-** [[the xUnpin() page cache method]]
-** ^xUnpin() is called by SQLite with a pointer to a currently pinned page
-** as its second argument.  If the third parameter, discard, is non-zero,
-** then the page must be evicted from the cache.
-** ^If the discard parameter is
-** zero, then the page may be discarded or retained at the discretion of
-** page cache implementation. ^The page cache implementation
-** may choose to evict unpinned pages at any time.
-**
-** The cache must not perform any reference counting. A single 
-** call to xUnpin() unpins the page regardless of the number of prior calls 
-** to xFetch().
-**
-** [[the xRekey() page cache methods]]
-** The xRekey() method is used to change the key value associated with the
-** page passed as the second argument. If the cache
-** previously contains an entry associated with newKey, it must be
-** discarded. ^Any prior cache entry associated with newKey is guaranteed not
-** to be pinned.
-**
-** When SQLite calls the xTruncate() method, the cache must discard all
-** existing cache entries with page numbers (keys) greater than or equal
-** to the value of the iLimit parameter passed to xTruncate(). If any
-** of these pages are pinned, they are implicitly unpinned, meaning that
-** they can be safely discarded.
-**
-** [[the xDestroy() page cache method]]
-** ^The xDestroy() method is used to delete a cache allocated by xCreate().
-** All resources associated with the specified cache should be freed. ^After
-** calling the xDestroy() method, SQLite considers the [sqlite3_pcache*]
-** handle invalid, and will not use it with any other sqlite3_pcache_methods2
-** functions.
-**
-** [[the xShrink() page cache method]]
-** ^SQLite invokes the xShrink() method when it wants the page cache to
-** free up as much of heap memory as possible.  The page cache implementation
-** is not obligated to free any memory, but well-behaved implementations should
-** do their best.

-**
-** However, the application must guarantee that the destination 
-** [database connection] is not passed to any other API (by any thread) after 
-** sqlite3_backup_init() is called and before the corresponding call to
-** sqlite3_backup_finish().  SQLite does not currently check to see
-** if the application incorrectly accesses the destination [database connection]
-** and so no error code is reported, but the operations may malfunction
-** nevertheless.  Use of the destination database connection while a

-**
-** If running in [shared cache mode], the application must
-** guarantee that the shared cache used by the destination database
-** is not accessed while the backup is running. In practice this means
-** that the application must guarantee that the disk file being 
-** backed up to is not accessed by any connection within the process,
-** not just the specific connection that was passed to sqlite3_backup_init().
-**
-** The [sqlite3_backup] object itself is partially threadsafe. Multiple

-** CAPI3REF: Unlock Notification
-** METHOD: sqlite3
-**
-** ^When running in shared-cache mode, a database operation may fail with
-** an [SQLITE_LOCKED] error if the required locks on the shared-cache or
-** individual tables within the shared-cache cannot be obtained. See
-** [SQLite Shared-Cache Mode] for a description of shared-cache locking. 
-** ^This API may be used to register a callback that SQLite will invoke 
-** when the connection currently holding the required lock relinquishes it.
-** ^This API is only available if the library was compiled with the
-** [SQLITE_ENABLE_UNLOCK_NOTIFY] C-preprocessor symbol defined.
-**
-** See Also: [Using the SQLite Unlock Notification Feature].
-**
-** ^Shared-cache locks are released when a database connection concludes
-** its current transaction, either by committing it or rolling it back. 
-**
-** ^When a connection (known as the blocked connection) fails to obtain a
-** shared-cache lock and SQLITE_LOCKED is returned to the caller, the
-** identity of the database connection (the blocking connection) that
-** has locked the required resource is stored internally. ^After an 
-** application receives an SQLITE_LOCKED error, it may call the
-** sqlite3_unlock_notify() method with the blocked connection handle as 
-** the first argument to register for a callback that will be invoked
-** when the blocking connections current transaction is concluded. ^The
-** callback is invoked from within the [sqlite3_step] or [sqlite3_close]
-** call that concludes the blocking connections transaction.
-**
-** ^(If sqlite3_unlock_notify() is called in a multi-threaded application,
-** there is a chance that the blocking connection will have already
-** concluded its transaction by the time sqlite3_unlock_notify() is invoked.
-** If this happens, then the specified callback is invoked immediately,
-** from within the call to sqlite3_unlock_notify().)^
-**
-** ^If the blocked connection is attempting to obtain a write-lock on a
-** shared-cache table, and more than one other connection currently holds
-** a read-lock on the same table, then SQLite arbitrarily selects one of 
-** the other connections to use as the blocking connection.
-**
-** ^(There may be at most one unlock-notify callback registered by a 
-** blocked connection. If sqlite3_unlock_notify() is called when the
-** blocked connection already has a registered unlock-notify callback,
-** then the new callback replaces the old.)^ ^If sqlite3_unlock_notify() is
-** called with a NULL pointer as its second argument, then any existing
-** unlock-notify callback is canceled. ^The blocked connections 
-** unlock-notify callback may also be canceled by closing the blocked
-** connection using [sqlite3_close()].
-**
-** The unlock-notify callback is not reentrant. If an application invokes
-** any sqlite3_xxx API functions from within an unlock-notify callback, a
-** crash or deadlock may be the result.
-**
-** ^Unless deadlock is detected (see below), sqlite3_unlock_notify() always
-** returns SQLITE_OK.
-**
-** <b>Callback Invocation Details</b>
-**
-** When an unlock-notify callback is registered, the application provides a 
-** single void* pointer that is passed to the callback when it is invoked.
-** However, the signature of the callback function allows SQLite to pass
-** it an array of void* context pointers. The first argument passed to
-** an unlock-notify callback is a pointer to an array of void* pointers,
-** and the second is the number of entries in the array.
-**
-** When a blocking connections transaction is concluded, there may be
-** more than one blocked connection that has registered for an unlock-notify
-** callback. ^If two or more such blocked connections have specified the
-** same callback function, then instead of invoking the callback function
-** multiple times, it is invoked once with the set of void* context pointers
-** specified by the blocked connections bundled together into an array.
-** This gives the application an opportunity to prioritize any actions 
-** related to the set of unblocked database connections.
-**
-** <b>Deadlock Detection</b>
-**
-** Assuming that after registering for an unlock-notify callback a 
-** database waits for the callback to be issued before taking any further
-** action (a reasonable assumption), then using this API may cause the
-** application to deadlock. For example, if connection X is waiting for
-** connection Y's transaction to be concluded, and similarly connection
-** Y is waiting on connection X's transaction, then neither connection
-** will proceed and the system may remain deadlocked indefinitely.
-**
-** To avoid this scenario, the sqlite3_unlock_notify() performs deadlock
-** detection. ^If a given call to sqlite3_unlock_notify() would put the
-** system in a deadlocked state, then SQLITE_LOCKED is returned and no
-** unlock-notify callback is registered. The system is said to be in
-** a deadlocked state if connection A has registered for an unlock-notify
-** callback on the conclusion of connection B's transaction, and connection
-** B has itself registered for an unlock-notify callback when connection
-** A's transaction is concluded. ^Indirect deadlock is also detected, so
-** the system is also considered to be deadlocked if connection B has
-** registered for an unlock-notify callback on the conclusion of connection
-** C's transaction, where connection C is waiting on connection A. ^Any
-** number of levels of indirection are allowed.
-**
-** <b>The "DROP TABLE" Exception</b>
-**
-** When a call to [sqlite3_step()] returns SQLITE_LOCKED, it is almost 
-** always appropriate to call sqlite3_unlock_notify(). There is however,
-** one exception. When executing a "DROP TABLE" or "DROP INDEX" statement,
-** SQLite checks if there are any currently executing SELECT statements
-** that belong to the same connection. If there are, SQLITE_LOCKED is
-** returned. In this case there is no "blocking connection", so invoking
-** sqlite3_unlock_notify() results in the unlock-notify callback being
-** invoked immediately. If the application then re-attempts the "DROP TABLE"
-** or "DROP INDEX" query, an infinite loop might be the result.
-**
-** One way around this problem is to check the extended error code returned
-** by an sqlite3_step() call. ^(If there is a blocking connection, then the
-** extended error code is set to SQLITE_LOCKED_SHAREDCACHE. Otherwise, in
-** the special "DROP TABLE/INDEX" case, the extended error code is just 
-** SQLITE_LOCKED.)^

-** <dt>SQLITE_VTAB_CONSTRAINT_SUPPORT
-** <dd>Calls of the form
-** [sqlite3_vtab_config](db,SQLITE_VTAB_CONSTRAINT_SUPPORT,X) are supported,
-** where X is an integer.  If X is zero, then the [virtual table] whose
-** [xCreate] or [xConnect] method invoked [sqlite3_vtab_config()] does not
-** support constraints.  In this configuration (which is the default) if
-** a call to the [xUpdate] method returns [SQLITE_CONSTRAINT], then the entire
-** statement is rolled back as if [ON CONFLICT | OR ABORT] had been
-** specified as part of the users SQL statement, regardless of the actual
-** ON CONFLICT mode specified.
-**
-** If X is non-zero, then the virtual table implementation guarantees
-** that if [xUpdate] returns [SQLITE_CONSTRAINT], it will do so before
-** any modifications to internal or persistent data structures have been made.
-** If the [ON CONFLICT] mode is ABORT, FAIL, IGNORE or ROLLBACK, SQLite 
-** is able to roll back a statement or database transaction, and abandon
-** or continue processing the current SQL statement as appropriate. 
-** If the ON CONFLICT mode is REPLACE and the [xUpdate] method returns
-** [SQLITE_CONSTRAINT], SQLite handles this as if the ON CONFLICT mode
-** had been ABORT.
-**
-** Virtual table implementations that are required to handle OR REPLACE
-** must do so within the [xUpdate] method. If a call to the 
-** [sqlite3_vtab_on_conflict()] function indicates that the current ON 
-** CONFLICT policy is REPLACE, the virtual table implementation should 
-** silently replace the appropriate rows within the xUpdate callback and
-** return SQLITE_OK. Or, if this is not possible, it may return
-** SQLITE_CONSTRAINT, in which case SQLite falls back to OR ABORT

-** The following three macros, FUNCTION(), LIKEFUNC() and AGGREGATE() are

-**
-**   FUNCTION(zName, nArg, iArg, bNC, xFunc)
-**     Used to create a scalar function definition of a function zName
-**     implemented by C function xFunc that accepts nArg arguments. The
-**     value passed as iArg is cast to a (void*) and made available
-**     as the user-data (sqlite3_user_data()) for the function. If
-**     argument bNC is true, then the SQLITE_FUNC_NEEDCOLL flag is set.
-**
-**   VFUNCTION(zName, nArg, iArg, bNC, xFunc)
-**     Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag.
-**
-**   DFUNCTION(zName, nArg, iArg, bNC, xFunc)
-**     Like FUNCTION except it omits the SQLITE_FUNC_CONSTANT flag and
-**     adds the SQLITE_FUNC_SLOCHNG flag.  Used for date & time functions
-**     and functions like sqlite_version() that can change, but not during
-**     a single query.  The iArg is ignored.  The user-data is always set
-**     to a NULL pointer.  The bNC parameter is not used.
-**
-**   PURE_DATE(zName, nArg, iArg, bNC, xFunc)
-**     Used for "pure" date/time functions, this macro is like DFUNCTION
-**     except that it does set the SQLITE_FUNC_CONSTANT flags.  iArg is
-**     ignored and the user-data for these functions is set to an 
-**     arbitrary non-NULL pointer.  The bNC parameter is not used.
-**
-**   AGGREGATE(zName, nArg, iArg, bNC, xStep, xFinal)
-**     Used to create an aggregate function definition implemented by
-**     the C functions xStep and xFinal. The first four parameters
-**     are interpreted in the same way as the first 4 parameters to
-**     FUNCTION().
-**
-**   LIKEFUNC(zName, nArg, pArg, flags)
-**     Used to create a scalar function definition of a function zName
-**     that accepts nArg arguments and is implemented by a call to C
-**     function likeFunc. Argument pArg is cast to a (void *) and made
-**     available as the function user-data (sqlite3_user_data()). The
-**     FuncDef.flags variable is set to the value passed as the flags
-**     parameter.

-** If the database schema is shared, then there is one instance of this
-** structure for each database connection (sqlite3*) that uses the shared
-** schema. This is because each database connection requires its own unique
-** instance of the sqlite3_vtab* handle used to access the virtual table
-** implementation. sqlite3_vtab* handles can not be shared between
-** database connections, even when the rest of the in-memory database
-** schema is shared, as the implementation often stores the database
-** connection handle passed to it via the xConnect() or xCreate() method
-** during initialization internally. This database connection handle may
-** then be used by the virtual table implementation to access real tables
-** within the database. So that they appear as part of the callers
-** transaction, these accesses need to be made via the same database
-** connection as that used to execute SQL operations on the virtual table.
-**
-** All VTable objects that correspond to a single table in a shared
-** database schema are initially stored in a linked-list pointed to by
-** the Table.pVTable member variable of the corresponding Table object.
-** When an sqlite3_prepare() operation is required to access the virtual
-** table, it searches the list for the VTable that corresponds to the
-** database connection doing the preparing so as to use the correct
-** sqlite3_vtab* handle in the compiled query.
-**
-** When an in-memory Table object is deleted (for example when the
-** schema is being reloaded for some reason), the VTable objects are not
-** deleted and the sqlite3_vtab* handles are not xDisconnect()ed
-** immediately. Instead, they are moved from the Table.pVTable list to
-** another linked list headed by the sqlite3.pDisconnect member of the
-** corresponding sqlite3 structure. They are then deleted/xDisconnected
-** next time a statement is prepared using said sqlite3*. This is done
-** to avoid deadlock issues involving multiple sqlite3.mutex mutexes.
-** Refer to comments above function sqlite3VtabUnlockList() for an
-** explanation as to why it is safe to add an entry to an sqlite3.pDisconnect

-** SQLite supports many different ways to resolve a constraint
-** error.  ROLLBACK processing means that a constraint violation
-** causes the operation in process to fail and for the current transaction
-** to be rolled back.  ABORT processing means the operation in process
-** fails and any prior changes from that one operation are backed out,
-** but the transaction is not rolled back.  FAIL processing means that
-** the operation in progress stops and returns an error code.  But prior
-** changes due to the same operation are not backed out and no rollback
-** occurs.  IGNORE means that the particular row that caused the constraint
-** error is not inserted or updated.  Processing continues and no error
-** is returned.  REPLACE means that preexisting database rows that caused
-** a UNIQUE constraint violation are removed so that the new insert or
-** update can proceed.  Processing continues and no error is reported.
-**
-** RESTRICT, SETNULL, and CASCADE actions apply only to foreign keys.
-** RESTRICT is the same as ABORT for IMMEDIATE foreign keys and the
-** same as ROLLBACK for DEFERRED keys.  SETNULL means that the foreign
-** key is set to NULL.  CASCADE means that a DELETE or UPDATE of the
-** referenced table row is propagated into the row that holds the
-** foreign key.
-**
-** The following symbolic values are used to record which type
-** of action to take.

-** This object holds a record which has been parsed out into individual

-**
-** A record is an object that contains one or more fields of data.
-** Records are used to store the content of a table row and to store
-** the key of an index.  A blob encoding of a record is created by
-** the OP_MakeRecord opcode of the VDBE and is disassembled by the

-**
-** An instance of this object serves as a "key" for doing a search on

-** just a prefix of the key.  The number of fields is given by
-** pKeyInfo->nField.
-**
-** The r1 and r2 fields are the values to return if this key is less than
-** or greater than a key in the btree, respectively.  These are normally
-** -1 and +1 respectively, but might be inverted to +1 and -1 if the b-tree
-** is in DESC order.
-**
-** The key comparison functions actually return default_rc when they find
-** an equals comparison.  default_rc can be -1, 0, or +1.  If there are
-** multiple entries in the b-tree with the same key (when only looking
-** at the first pKeyInfo->nFields,) then default_rc can be set to -1 to
-** cause the search to find the last match, or +1 to cause the search to
-** find the first match.
-**
-** The key comparison functions will set eqSeen to true if they ever
-** get and equal results when comparing this structure to a b-tree record.
-** When default_rc!=0, the search might end up on the record immediately
-** before the first match or immediately after the last match.  The
-** eqSeen field will indicate whether or not an exact match exists in the

-** Each SQL index is represented in memory by an
-** instance of the following structure.
-**
-** The columns of the table that are to be indexed are described
-** by the aiColumn[] field of this structure.  For example, suppose
-** we have the following table and index:
-**
-**     CREATE TABLE Ex1(c1 int, c2 int, c3 text);
-**     CREATE INDEX Ex2 ON Ex1(c3,c1);
-**
-** In the Table structure describing Ex1, nCol==3 because there are
-** three columns in the table.  In the Index structure describing
-** Ex2, nColumn==2 since 2 of the 3 columns of Ex1 are indexed.
-** The value of aiColumn is {2, 0}.  aiColumn[0]==2 because the
-** first column to be indexed (c3) has an index of 2 in Ex1.aCol[].
-** The second column to be indexed (c1) has an index of 0 in
-** Ex1.aCol[], hence Ex2.aiColumn[1]==0.
-**
-** The Index.onError field determines whether or not the indexed columns
-** must be unique and what to do if they are not.  When Index.onError=OE_None,
-** it means this is not a unique index.  Otherwise it is a unique index
-** and the value of Index.onError indicate the which conflict resolution
-** algorithm to employ whenever an attempt is made to insert a non-unique
-** element.

-** of this structure may be created. In this case the Index.tnum variable is
-** used to store the address of a VDBE instruction, not a database page
-** number (it cannot - the database page is not allocated until the VDBE
-** program is executed). See convertToWithoutRowidTable() for details.

-** as opcodes here. For example, the parser defines TK_GE to be an integer
-** code representing the ">=" operator. This same integer code is reused
-** to represent the greater-than-or-equal-to operator in the expression
-** tree.
-**
-** If the expression is an SQL literal (TK_INTEGER, TK_FLOAT, TK_BLOB,
-** or TK_STRING), then Expr.token contains the text of the SQL literal. If
-** the expression is a variable (TK_VARIABLE), then Expr.token contains the
-** variable name. Finally, if the expression is an SQL function (TK_FUNCTION),
-** then Expr.token contains the name of the function.
-**
-** Expr.pRight and Expr.pLeft are the left and right subexpressions of a
-** binary operator. Either or both may be NULL.
-**
-** Expr.x.pList is a list of arguments if the expression is an SQL function,
-** a CASE expression or an IN expression of the form "<lhs> IN (<y>, <z>...)".
-** Expr.x.pSelect is used if the expression is a sub-select or an expression of
-** the form "<lhs> IN (SELECT ...)". If the EP_xIsSelect bit is set in the
-** Expr.flags mask, then Expr.x.pSelect is valid. Otherwise, Expr.x.pList is
-** valid.
-**
-** An expression of the form ID or ID.ID refers to a column in a table.
-** For such expressions, Expr.op is set to TK_COLUMN and Expr.iTable is
-** the integer cursor number of a VDBE cursor pointing to that table and
-** Expr.iColumn is the column number for the specific column.  If the
-** expression is used as a result in an aggregate SELECT, then the
-** value is also stored in the Expr.iAgg column in the aggregate so that
-** it can be accessed after all aggregates are computed.
-**
-** If the expression is an unbound variable marker (a question mark
-** character '?' in the original SQL) then the Expr.iTable holds the index
-** number for that variable.
-**
-** If the expression is a subquery then Expr.iColumn holds an integer
-** register number containing the result of the subquery.  If the
-** subquery gives a constant result, then iTable is -1.  If the subquery
-** gives a different answer at different times during statement processing
-** then iTable is the address of a subroutine that computes the subquery.
-**
-** If the Expr is of type OP_Column, and the table it is selecting from
-** is a disk table or the "old.*" pseudo-table, then pTab points to the
-** corresponding table definition.
-**
-** ALLOCATION NOTES:
-**
-** Expr objects can use a lot of memory space in database schema.  To
-** help reduce memory requirements, sometimes an Expr object will be
-** truncated.  And to reduce the number of memory allocations, sometimes
-** two or more Expr objects will be stored in a single memory allocation,
-** together with Expr.zToken strings.
-**
-** If the EP_Reduced and EP_TokenOnly flags are set when
-** an Expr object is truncated.  When EP_Reduced is set, then all
-** the child Expr objects in the Expr.pLeft and Expr.pRight subtrees
-** are contained within the same memory allocation.  Note, however, that
-** the subtrees in Expr.x.pList or Expr.x.pSelect are always separately
-** allocated, regardless of whether or not EP_Reduced is set.

-**
-**     SRT_Except      Remove results from the temporary index pDest->iSDParm.
-**
-**     SRT_Exists      Store a 1 in memory cell pDest->iSDParm if the result
-**                     set is not empty.
-**
-**     SRT_Discard     Throw the results away.  This is used by SELECT
-**                     statements within triggers whose only purpose is
-**                     the side-effects of functions.
-**
-** All of the above are free to ignore their ORDER BY clause. Those that
-** follow must honor the ORDER BY clause.
-**
-**     SRT_Output      Generate a row of output (using the OP_ResultRow
-**                     opcode) for each row in the result set.
-**
-**     SRT_Mem         Only valid if the result is a single column.
-**                     Store the first column of the first result row
-**                     in register pDest->iSDParm then abandon the rest
-**                     of the query.  This destination implies "LIMIT 1".
-**
-**     SRT_Set         The result must be a single column.  Store each
-**                     row of result as the key in table pDest->iSDParm.
-**                     Apply the affinity pDest->affSdst before storing
-**                     results.  Used to implement "IN (SELECT ...)".
-**
-**     SRT_EphemTab    Create an temporary table pDest->iSDParm and store
-**                     the result there. The cursor is left open after
-**                     returning.  This is like SRT_Table except that
-**                     this destination uses OP_OpenEphemeral to create
-**                     the table first.
-**
-**     SRT_Coroutine   Generate a co-routine that returns a new row of
-**                     results each time it is invoked.  The entry point
-**                     of the co-routine is stored in register pDest->iSDParm
-**                     and the result row is stored in pDest->nDest registers
-**                     starting with pDest->iSdst.
-**
-**     SRT_Table       Store results in temporary table pDest->iSDParm.
-**     SRT_Fifo        This is like SRT_EphemTab except that the table
-**                     is assumed to already be open.  SRT_Fifo has
-**                     the additional property of being able to ignore
-**                     the ORDER BY clause.
-**
-**     SRT_DistFifo    Store results in a temporary table pDest->iSDParm.
-**                     But also use temporary table pDest->iSDParm+1 as
-**                     a record of all prior results and ignore any duplicate
-**                     rows.  Name means:  "Distinct Fifo".
-**
-**     SRT_Queue       Store results in priority queue pDest->iSDParm (really
-**                     an index).  Append a sequence number so that all entries
-**                     are distinct.
-**
-**     SRT_DistQueue   Store results in priority queue pDest->iSDParm only if
-**                     the same record has never been stored before.  The

-**
-** This function is used to test that SQLite selects the correct user
-** function callback when multiple versions (for different text encodings)
-** are available.
-**
-** Calling this routine registers up to three versions of the user function
-** "test_function" with database handle <db>.  If the second argument is
-** true, then a version of test_function is registered for UTF-8, if the
-** third is true, a version is registered for UTF-16le, if the fourth is
-** true, a UTF-16be version is available.  Previous versions of
-** test_function are deleted.
-**
-** The user function is implemented by calling the following TCL script:
-**
-**   "test_function <enc> <arg>"
-**
-** Where <enc> is one of UTF-8, UTF-16LE or UTF16BE, and <arg> is the
-** single argument passed to the SQL function. The value returned by
-** the TCL script is used as the return value of the SQL function. It
-** is passed to SQLite using UTF-16BE for a UTF-8 test_function(), UTF-8
-** for a UTF-16LE test_function(), and UTF-16LE for an implementation that
-** prefers UTF-16BE.

-/*
-** Method:
-**
-**   This layer is implemented as a wrapper around the "real" 
-**   sqlite3_file object for the host system. Each time data is 
-**   written to the file object, instead of being written to the
-**   underlying file, the write operation is stored in an in-memory 
-**   structure (type WriteBuffer). This structure is placed at the
-**   end of a global ordered list (the write-list).
-**
-**   When data is read from a file object, the requested region is
-**   first retrieved from the real file. The write-list is then 
-**   traversed and data copied from any overlapping WriteBuffer 
-**   structures to the output buffer. i.e. a read() operation following
-**   one or more write() operations works as expected, even if no
-**   data has actually been written out to the real file.
-**
-**   When a fsync() operation is performed, an operating system crash 
-**   may be simulated, in which case exit(-1) is called (the call to 
-**   xSync() never returns). Whether or not a crash is simulated,
-**   the data associated with a subset of the WriteBuffer structures 
-**   stored in the write-list is written to the real underlying files 
-**   and the entries removed from the write-list. If a crash is simulated,
-**   a subset of the buffers may be corrupted before the data is written.
-**
-**   The exact subset of the write-list written and/or corrupted is
-**   determined by the simulated device characteristics and sector-size.
-**
-** "Normal" mode:
-**
-**   Normal mode is used when the simulated device has none of the
-**   SQLITE_IOCAP_XXX flags set.
-**
-**   In normal mode, if the fsync() is not a simulated crash, the 
-**   write-list is traversed from beginning to end. Each WriteBuffer
-**   structure associated with the file handle used to call xSync()
-**   is written to the real file and removed from the write-list.
-**
-**   If a crash is simulated, one of the following takes place for 
-**   each WriteBuffer in the write-list, regardless of which 
-**   file-handle it is associated with:
-**
-**     1. The buffer is correctly written to the file, just as if
-**        a crash were not being simulated.
-**
-**     2. Nothing is done.
-**
-**     3. Garbage data is written to all sectors of the file that 
-**        overlap the region specified by the WriteBuffer. Or garbage
-**        data is written to some contiguous section within the 
-**        overlapped sectors.
-**
-** Device Characteristic flag handling:
-**
-**   If the IOCAP_ATOMIC flag is set, then option (3) above is 
-**   never selected.
-**
-**   If the IOCAP_ATOMIC512 flag is set, and the WriteBuffer represents
-**   an aligned write() of an integer number of 512 byte regions, then
-**   option (3) above is never selected. Instead, each 512 byte region
-**   is either correctly written or left completely untouched. Similar
-**   logic governs the behavior if any of the other ATOMICXXX flags
-**   is set.
-**
-**   If either the IOCAP_SAFEAPPEND or IOCAP_SEQUENTIAL flags are set
-**   and a crash is being simulated, then an entry of the write-list is
-**   selected at random. Everything in the list after the selected entry 
-**   is discarded before processing begins.
-**
-**   If IOCAP_SEQUENTIAL is set and a crash is being simulated, option 
-**   (1) is selected for all write-list entries except the last. If a 
-**   crash is not being simulated, then all entries in the write-list
-**   that occur before at least one write() on the file-handle specified
-**   as part of the xSync() are written to their associated real files.
-**
-**   If IOCAP_SAFEAPPEND is set and the first byte written by the write()
-**   operation is one byte past the current end of the file, then option
-**   (1) is always selected.

-** Code for testing the virtual table xBestIndex method and the query
-** planner.
-*/
-
-
-/*
-** INSTRUCTIONS
-**
-** This module exports a single tcl command - [register_tcl_module]. When
-** invoked, it registers a special virtual table module with a database
-** connection.
-**
-** The virtual table is currently read-only. And always returns zero rows.
-** It is created with a single argument - the name of a Tcl command - as
-** follows:
-**
-**   CREATE VIRTUAL TABLE x1 USING tcl(tcl_command);
-**
-** The command [tcl_command] is invoked when the table is first created (or
-** connected), when the xBestIndex() method is invoked and when the xFilter()
-** method is called. When it is created (or connected), it is invoked as
-** follows:
-**
-**   tcl_command xConnect
-**
-** In this case the return value of the script is passed to the
-** sqlite3_declare_vtab() function to create the virtual table schema.
-**
-** When the xBestIndex() method is called by SQLite, the Tcl command is
-** invoked as:
-**
-**   tcl_command xBestIndex CONSTRAINTS ORDERBY MASK
-**
-** where CONSTRAINTS is a tcl representation of the aConstraints[] array,
-** ORDERBY is a representation of the contents of the aOrderBy[] array and
-** MASK is a copy of sqlite3_index_info.colUsed. For example if the virtual
-** table is declared as:
-**
-**   CREATE TABLE x1(a, b, c)
-**
-** and the query is:
-**
-**   SELECT * FROM x1 WHERE a=? AND c<? ORDER BY b, c;
-**
-** then the Tcl command is:
-**
-**   tcl_command xBestIndex                                  \
-**     {{op eq column 0 usable 1} {op lt column 2 usable 1}} \
-**     {{column 1 desc 0} {column 2 desc 0}}                 \
-**     7
-**
-** The return value of the script is a list of key-value pairs used to
-** populate the output fields of the sqlite3_index_info structure. Possible
-** keys and the usage of the accompanying values are:
-** 
-**   "orderby"          (value of orderByConsumed flag)
-**   "cost"             (value of estimatedCost field)
-**   "rows"             (value of estimatedRows field)
-**   "use"              (index of used constraint in aConstraint[])
-**   "omit"             (like "use", but also sets omit flag)
-**   "idxnum"           (value of idxNum field)
-**   "idxstr"           (value of idxStr field)
-**
-** Refer to code below for further details.
-**
-** When SQLite calls the xFilter() method, this module invokes the following
-** Tcl script:
-**
-**   tcl_command xFilter IDXNUM IDXSTR ARGLIST
-**
-** IDXNUM and IDXSTR are the values of the idxNum and idxStr parameters
-** passed to xFilter. ARGLIST is a Tcl list containing each of the arguments
-** passed to xFilter in text form.
-**
-** As with xBestIndex(), the return value of the script is interpreted as a
-** list of key-value pairs. There is currently only one key defined - "sql".
-** The value must be the full text of an SQL statement that returns the data
-** for the current scan. The leftmost column returned by the SELECT is assumed
-** to contain the rowid. Other columns must follow, in order from left to
-** right.

-*************************************************************************
-**
-** This file implements an example of a simple VFS implementation that 
-** omits complex features often not required or not possible on embedded
-** platforms.  Code is included to buffer writes to the journal file, 
-** which can be a significant performance improvement on some embedded
-** platforms.
-**
-** OVERVIEW
-**
-**   The code in this file implements a minimal SQLite VFS that can be 
-**   used on Linux and other posix-like operating systems. The following 
-**   system calls are used:
-**
-**    File-system: access(), unlink(), getcwd()
-**    File IO:     open(), read(), write(), fsync(), close(), fstat()
-**    Other:       sleep(), usleep(), time()
-**
-**   The following VFS features are omitted:
-**
-**     1. File locking. The user must ensure that there is at most one
-**        connection to each database when using this VFS. Multiple
-**        connections to a single shared-cache count as a single connection
-**        for the purposes of the previous statement.
-**
-**     2. The loading of dynamic extensions (shared libraries).
-**
-**     3. Temporary files. The user must configure SQLite to use in-memory
-**        temp files when using this VFS. The easiest way to do this is to
-**        compile with:
-**
-**          -DSQLITE_TEMP_STORE=3
-**
-**     4. File truncation. As of version 3.6.24, SQLite may run without
-**        a working xTruncate() call, providing the user does not configure
-**        SQLite to use "journal_mode=truncate", or use both
-**        "journal_mode=persist" and ATTACHed databases.
-**
-**   It is assumed that the system uses UNIX-like path-names. Specifically,
-**   that '/' characters are used to separate path components and that
-**   a path-name is a relative path unless it begins with a '/'. And that
-**   no UTF-8 encoded paths are greater than 512 bytes in length.
-**
-** JOURNAL WRITE-BUFFERING
-**
-**   To commit a transaction to the database, SQLite first writes rollback
-**   information into the journal file. This usually consists of 4 steps:
-**
-**     1. The rollback information is sequentially written into the journal
-**        file, starting at the start of the file.
-**     2. The journal file is synced to disk.
-**     3. A modification is made to the first few bytes of the journal file.
-**     4. The journal file is synced to disk again.
-**
-**   Most of the data is written in step 1 using a series of calls to the
-**   VFS xWrite() method. The buffers passed to the xWrite() calls are of
-**   various sizes. For example, as of version 3.6.24, when committing a 
-**   transaction that modifies 3 pages of a database file that uses 4096 
-**   byte pages residing on a media with 512 byte sectors, SQLite makes 
-**   eleven calls to the xWrite() method to create the rollback journal,

-**
-**   On many operating systems, this is an efficient way to write to a file.
-**   However, on some embedded systems that do not cache writes in OS 
-**   buffers it is much more efficient to write data in blocks that are
-**   an integer multiple of the sector-size in size and aligned at the
-**   start of a sector.
-**
-**   To work around this, the code in this file allocates a fixed size
-**   buffer of SQLITE_DEMOVFS_BUFFERSZ using sqlite3_malloc() whenever a 
-**   journal file is opened. It uses the buffer to coalesce sequential
-**   writes into aligned SQLITE_DEMOVFS_BUFFERSZ blocks. When SQLite
-**   invokes the xSync() method to sync the contents of the file to disk,
-**   all accumulated data is written out, even if it does not constitute
-**   a complete block. This means the actual IO to create the rollback 
-**   journal for the example transaction above is this:
-**
-**             Write offset | Bytes written
-**             ----------------------------
-**                        0           8192
-**                     8192           4632
-**             ++++++++++++SYNC+++++++++++
-**                        0             12
-**             ++++++++++++SYNC+++++++++++
-**
-**   Much more efficient if the underlying OS is not caching write 
-**   operations.

-** a legal notice, here is a blessing:

-*************************************************************************
-** Code for testing the virtual table interfaces.  This code
-** is not included in the SQLite library.  It is used for automated
-** testing of the SQLite library.
-**
-** The FS virtual table is created as follows:
-**
-**   CREATE VIRTUAL TABLE tbl USING fs(idx);
-**
-** where idx is the name of a table in the db with 2 columns.  The virtual
-** table also has two columns - file path and file contents.
-**
-** The first column of table idx must be an IPK, and the second contains file
-** paths. For example:
-**
-**   CREATE TABLE idx(id INTEGER PRIMARY KEY, path TEXT);
-**   INSERT INTO idx VALUES(4, '/etc/passwd');
-**
-** Adding the row to the idx table automatically creates a row in the 
-** virtual table with rowid=4, path=/etc/passwd and a text field that 
-** contains data read from file /etc/passwd on disk.
-**
-*************************************************************************
-** Virtual table module "fsdir"
-**
-** This module is designed to be used as a read-only eponymous virtual table.
-** Its schema is as follows:
-**
-**   CREATE TABLE fsdir(dir TEXT, name TEXT);
-**
-** When queried, a WHERE term of the form "dir = $dir" must be provided. The
-** virtual table then appears to have one row for each entry in file-system
-** directory $dir. Column dir contains a copy of $dir, and column "name"
-** contains the name of the directory entry.
-**
-** If the specified $dir cannot be opened or is not a directory, it is not
-** an error. The virtual table appears to be empty in this case.
-**
-*************************************************************************
-** Virtual table module "fstree"
-**
-** This module is also a read-only eponymous virtual table with the 
-** following schema:
-**
-**   CREATE TABLE fstree(path TEXT, size INT, data BLOB);
-**
-** Running a "SELECT * FROM fstree" query on this table returns the entire
-** contents of the file-system, starting at "/". To restrict the search
-** space, the virtual table supports LIKE and GLOB constraints on the
-** 'path' column. For example:
-**
-**   SELECT * FROM fstree WHERE path LIKE '/home/dan/sqlite/%'

-*************************************************************************
-**
-** This is the C-language interface definition for the "intarray" or
-** integer array virtual table for SQLite.
-**
-** The intarray virtual table is designed to facilitate using an
-** array of integers as the right-hand side of an IN operator.  So
-** instead of doing a prepared statement like this:
-**
-**     SELECT * FROM table WHERE x IN (?,?,?,...,?);
-**
-** And then binding indivdual integers to each of ? slots, a C-language
-** application can create an intarray object (named "ex1" in the following
-** example), prepare a statement like this:
-**
-**     SELECT * FROM table WHERE x IN ex1;
-**
-** Then bind an ordinary C/C++ array of integer values to the ex1 object
-** to run the statement.
-**
-** USAGE:
-**
-** One or more intarray objects can be created as follows:
-**
-**      sqlite3_intarray *p1, *p2, *p3;
-**      sqlite3_intarray_create(db, "ex1", &p1);
-**      sqlite3_intarray_create(db, "ex2", &p2);
-**      sqlite3_intarray_create(db, "ex3", &p3);
-**
-** Each call to sqlite3_intarray_create() generates a new virtual table
-** module and a singleton of that virtual table module in the TEMP
-** database.  Both the module and the virtual table instance use the
-** name given by the second parameter.  The virtual tables can then be
-** used in prepared statements:
-**
-**      SELECT * FROM t1, t2, t3
-**       WHERE t1.x IN ex1
-**         AND t2.y IN ex2
-**         AND t3.z IN ex3;
-**
-** Each integer array is initially empty.  New arrays can be bound to
-** an integer array as follows:
-**
-**     sqlite3_int64 a1[] = { 1, 2, 3, 4 };
-**     sqlite3_int64 a2[] = { 5, 6, 7, 8, 9, 10, 11 };
-**     sqlite3_int64 *a3 = sqlite3_malloc( 100*sizeof(sqlite3_int64) );
-**     // Fill in content of a3[]
-**     sqlite3_intarray_bind(p1, 4, a1, 0);
-**     sqlite3_intarray_bind(p2, 7, a2, 0);
-**     sqlite3_intarray_bind(p3, 100, a3, sqlite3_free);
-**
-** A single intarray object can be rebound multiple times.  But do not
-** attempt to change the bindings of an intarray while it is in the middle
-** of a query.
-**
-** The array that holds the integers is automatically freed by the function
-** in the fourth parameter to sqlite3_intarray_bind() when the array is no
-** longer needed.  The application must not change the intarray values
-** while an intarray is in the middle of a query.
-**
-** The intarray object is automatically destroyed when its corresponding
-** virtual table is dropped.  Since the virtual tables are created in the
-** TEMP database, they are automatically dropped when the database connection
-** closes so the application does not normally need to take any special
-** action to free the intarray objects.

-******************************************************************************
-**
-** This file contains code for a VFS layer that acts as a wrapper around
-** an existing VFS. The code in this file attempts to verify that SQLite
-** correctly populates and syncs a journal file before writing to a
-** corresponding database file.
-**
-** INTERFACE
-**
-**   The public interface to this wrapper VFS is two functions:
-**
-**     jt_register()
-**     jt_unregister()
-**
-**   See header comments associated with those two functions below for 
-**   details.
-**
-** LIMITATIONS
-**
-**   This wrapper will not work if "PRAGMA synchronous = off" is used.
-**
-** OPERATION
-**
-**  Starting a Transaction:
-**
-**   When a write-transaction is started, the contents of the database is
-**   inspected and the following data stored as part of the database file 
-**   handle (type struct jt_file):
-**
-**     a) The page-size of the database file.
-**     b) The number of pages that are in the database file.
-**     c) The set of page numbers corresponding to free-list leaf pages.
-**     d) A check-sum for every page in the database file.
-**
-**   The start of a write-transaction is deemed to have occurred when a 
-**   28-byte journal header is written to byte offset 0 of the journal 
-**   file.
-**
-**  Syncing the Journal File:
-**
-**   Whenever the xSync method is invoked to sync a journal-file, the
-**   contents of the journal file are read. For each page written to
-**   the journal file, a check-sum is calculated and compared to the  
-**   check-sum calculated for the corresponding database page when the
-**   write-transaction was initialized. The success of the comparison
-**   is assert()ed. So if SQLite has written something other than the
-**   original content to the database file, an assert() will fail.
-**
-**   Additionally, the set of page numbers for which records exist in
-**   the journal file is added to (unioned with) the set of page numbers
-**   corresponding to free-list leaf pages collected when the 
-**   write-transaction was initialized. This set comprises the page-numbers 
-**   corresponding to those pages that SQLite may now safely modify.
-**
-**  Writing to the Database File:
-**
-**   When a block of data is written to a database file, the following
-**   invariants are asserted:
-**
-**     a) That the block of data is an aligned block of page-size bytes.
-**
-**     b) That if the page being written did not exist when the 
-**        transaction was started (i.e. the database file is growing), then
-**        the journal-file must have been synced at least once since
-**        the start of the transaction.
-**
-**     c) That if the page being written did exist when the transaction 
-**        was started, then the page must have either been a free-list
-**        leaf page at the start of the transaction, or else must have
-**        been stored in the journal file prior to the most recent sync.
-**
-**  Closing a Transaction:
-**
-**   When a transaction is closed, all data collected at the start of
-**   the transaction, or following an xSync of a journal-file, is 
-**   discarded. The end of a transaction is recognized when any one 
-**   of the following occur:
-**
-**     a) A block of zeroes (or anything else that is not a valid 
-**        journal-header) is written to the start of the journal file.
-**
-**     b) A journal file is truncated to zero bytes in size using xTruncate.
-**
-**     c) The journal file is deleted using xDelete.

-*************************************************************************
-**
-** This file contains a VFS "shim" - a layer that sits in between the
-** pager and the real VFS - that breaks up a very large database file
-** into two or more smaller files on disk.  This is useful, for example,
-** in order to support large, multi-gigabyte databases on older filesystems
-** that limit the maximum file size to 2 GiB.
-**
-** USAGE:
-**
-** Compile this source file and link it with your application.  Then
-** at start-time, invoke the following procedure:
-**
-**   int sqlite3_multiplex_initialize(
-**      const char *zOrigVfsName,    // The underlying real VFS
-**      int makeDefault              // True to make multiplex the default VFS
-**   );
-**
-** The procedure call above will create and register a new VFS shim named
-** "multiplex".  The multiplex VFS will use the VFS named by zOrigVfsName to
-** do the actual disk I/O.  (The zOrigVfsName parameter may be NULL, in 
-** which case the default VFS at the moment sqlite3_multiplex_initialize()
-** is called will be used as the underlying real VFS.)  
-**
-** If the makeDefault parameter is TRUE then multiplex becomes the new
-** default VFS.  Otherwise, you can use the multiplex VFS by specifying
-** "multiplex" as the 4th parameter to sqlite3_open_v2() or by employing
-** URI filenames and adding "vfs=multiplex" as a parameter to the filename
-** URI.
-**
-** The multiplex VFS allows databases up to 32 GiB in size.  But it splits
-** the files up into smaller pieces, so that they will work even on 
-** filesystems that do not support large files.  The default chunk size
-** is 2147418112 bytes (which is 64KiB less than 2GiB) but this can be
-** changed at compile-time by defining the SQLITE_MULTIPLEX_CHUNK_SIZE
-** macro.  Use the "chunksize=NNNN" query parameter with a URI filename
-** in order to select an alternative chunk size for individual connections
-** at run-time.

-*************************************************************************
-**
-** OVERVIEW:
-**
-**   This file contains some example code demonstrating how the SQLite 
-**   vfs feature can be used to have SQLite operate directly on an 
-**   embedded media, without using an intermediate file system.
-**
-**   Because this is only a demo designed to run on a workstation, the
-**   underlying media is simulated using a regular file-system file. The
-**   size of the file is fixed when it is first created (default size 10 MB).
-**   From SQLite's point of view, this space is used to store a single
-**   database file and the journal file. 
-**
-**   Any statement journal created is stored in volatile memory obtained 
-**   from sqlite3_malloc(). Any attempt to create a temporary database file 
-**   will fail (SQLITE_IOERR). To prevent SQLite from attempting this,
-**   it should be configured to store all temporary database files in 
-**   main memory (see pragma "temp_store" or the SQLITE_TEMP_STORE compile 
-**   time option).
-**
-** ASSUMPTIONS:
-**
-**   After it has been created, the blob file is accessed using the
-**   following three functions only:
-**
-**       mediaRead();            - Read a 512 byte block from the file.
-**       mediaWrite();           - Write a 512 byte block to the file.
-**       mediaSync();            - Tell the media hardware to sync.
-**
-**   It is assumed that these can be easily implemented by any "real"
-**   media vfs driver adapting this code.
-**
-** FILE FORMAT:
-**
-**   The basic principle is that the "database file" is stored at the
-**   beginning of the 10 MB blob and grows in a forward direction. The 
-**   "journal file" is stored at the end of the 10MB blob and grows
-**   in the reverse direction. If, during a transaction, insufficient
-**   space is available to expand either the journal or database file,
-**   an SQLITE_FULL error is returned. The database file is never allowed
-**   to consume more than 90% of the blob space. If SQLite tries to
-**   create a file larger than this, SQLITE_FULL is returned.
-**
-**   No allowance is made for "wear-leveling", as is required by.
-**   embedded devices in the absence of equivalent hardware features.
-**
-**   The first 512 block byte of the file is reserved for storing the
-**   size of the "database file". It is updated as part of the sync()
-**   operation. On startup, it can only be trusted if no journal file
-**   exists. If a journal-file does exist, then it stores the real size
-**   of the database region. The second and subsequent blocks store the 
-**   actual database content.
-**
-**   The size of the "journal file" is not stored persistently in the 
-**   file. When the system is running, the size of the journal file is
-**   stored in volatile memory. When recovering from a crash, this vfs
-**   reports a very large size for the journal file. The normal journal
-**   header and checksum mechanisms serve to prevent SQLite from 
-**   processing any data that lies past the logical end of the journal.
-**
-**   When SQLite calls OsDelete() to delete the journal file, the final
-**   512 bytes of the blob (the area containing the first journal header)
-**   are zeroed.
-**
-** LOCKING:
-**
-**   File locking is a no-op. Only one connection may be open at any one
-**   time using this demo vfs.

-**
-** This file contains the implementation of an SQLite vfs wrapper that
-** adds instrumentation to all vfs and file methods. C and Tcl interfaces
-** are provided to control the instrumentation.
-*/
-
-/*
-** This module contains code for a wrapper VFS that causes a log of
-** most VFS calls to be written into a nominated file on disk. The log 
-** is stored in a compressed binary format to reduce the amount of IO 
-** overhead introduced into the application by logging.
-**
-** All calls on sqlite3_file objects except xFileControl() are logged.
-** Additionally, calls to the xAccess(), xOpen(), and xDelete()
-** methods are logged. The other sqlite3_vfs object methods (xDlXXX,
-** xRandomness, xSleep, xCurrentTime, xGetLastError and xCurrentTimeInt64) 
-** are not logged.
-**
-** The binary log files are read using a virtual table implementation
-** also contained in this file. 
-**
-** CREATING LOG FILES:
-**
-**       int sqlite3_vfslog_new(
-**         const char *zVfs,          // Name of new VFS
-**         const char *zParentVfs,    // Name of parent VFS (or NULL)
-**         const char *zLog           // Name of log file to write to
-**       );
-**
-**       int sqlite3_vfslog_finalize(const char *zVfs);
-**
-** ANNOTATING LOG FILES:
-**
-**   To write an arbitrary message into a log file:
-**
-**       int sqlite3_vfslog_annotate(const char *zVfs, const char *zMsg);
-**
-** READING LOG FILES:
-**
-**   Log files are read using the "vfslog" virtual table implementation
-**   in this file. To register the virtual table with SQLite, use:
-**
-**       int sqlite3_vfslog_register(sqlite3 *db);
-**
-**   Then, if the log file is named "vfs.log", the following SQL command:
-**
-**       CREATE VIRTUAL TABLE v USING vfslog('vfs.log');
-**
-**   creates a virtual table with 6 columns, as follows:
-**
-**       CREATE TABLE v(
-**         event    TEXT,             // "xOpen", "xRead" etc.
-**         file     TEXT,             // Name of file this call applies to
-**         clicks   INTEGER,          // Time spent in call
-**         rc       INTEGER,          // Return value
-**         size     INTEGER,          // Bytes read or written
-**         offset   INTEGER           // File offset read or written
-**       );

-** group.  If zPattern is new, then a new quota group is created.
-**
-** If the iLimit for a quota group is set to zero, then the quota group
-** is disabled and will be deleted when the last database connection using
-** the quota group is closed.
-**
-** Calling this routine on a zPattern that does not exist and with a
-** zero iLimit is a no-op.
-**
-** A quota group must exist with a non-zero iLimit prior to opening

-** This file contains the interface definition for the quota a VFS shim.
-**
-** This particular shim enforces a quota system on files.  One or more
-** database files are in a "quota group" that is defined by a GLOB
-** pattern.  A quota is set for the combined size of all files in the
-** the group.  A quota of zero means "no limit".  If the total size
-** of all files in the quota group is greater than the limit, then
-** write requests that attempt to enlarge a file fail with SQLITE_FULL.
-**
-** However, before returning SQLITE_FULL, the write requests invoke
-** a callback function that is configurable for each quota group.
-** This callback has the opportunity to enlarge the quota.  If the
-** callback does enlarge the quota such that the total size of all
-** files within the group is less than the new quota, then the write
-** continues as if nothing had happened.

-/*
-** Create or destroy a quota group.
-**
-** The quota group is defined by the zPattern.  When calling this routine
-** with a zPattern for a quota group that already exists, this routine
-** merely updates the iLimit, xCallback, and pArg values for that quota
-** group.  If zPattern is new, then a new quota group is created.
-**
-** The zPattern is always compared against the full pathname of the file.
-** Even if APIs are called with relative pathnames, SQLite converts the
-** name to a full pathname before comparing it against zPattern.  zPattern
-** is a glob pattern with the following matching rules:
-**
-**      '*'       Matches any sequence of zero or more characters.
-**
-**      '?'       Matches exactly one character.
-**
-**     [...]      Matches one character from the enclosed list of
-**                characters.  "]" can be part of the list if it is
-**                the first character.  Within the list "X-Y" matches
-**                characters X or Y or any character in between the
-**                two.  Ex:  "[0-9]" matches any digit.
-**
-**     [^...]     Matches one character not in the enclosed list.
-**
-**     /          Matches either / or \.  This allows glob patterns
-**                containing / to work on both unix and windows.
-**
-** Note that, unlike unix shell globbing, the directory separator "/"
-** can match a wildcard.  So, for example, the pattern "/abc/xyz/" "*"
-** matches any files anywhere in the directory hierarchy beneath
-** /abc/xyz.
-**
-** The glob algorithm works on bytes.  Multi-byte UTF8 characters are
-** matched as if each byte were a separate character.
-**
-** If the iLimit for a quota group is set to zero, then the quota group
-** is disabled and will be deleted when the last database connection using
-** the quota group is closed.
-**
-** Calling this routine on a zPattern that does not exist and with a
-** zero iLimit is a no-op.
-**
-** A quota group must exist with a non-zero iLimit prior to opening
-** database connections if those connections are to participate in the
-** quota group.  Creating a quota group does not affect database connections
-** that are already open.
-**
-** The patterns that define the various quota groups should be distinct.
-** If the same filename matches more than one quota group pattern, then
-** the behavior of this package is undefined.

-**
-******************************************************************************
-**
-** This file contains demonstration code.  Nothing in this file gets compiled
-** or linked into the SQLite library unless you use a non-standard option:
-**
-**      -DSQLITE_SERVER=1
-**
-** The configure script will never generate a Makefile with the option
-** above.  You will need to manually modify the Makefile if you want to
-** include any of the code from this file in your project.  Or, at your
-** option, you may copy and paste the code from this file and
-** thereby avoiding a recompile of SQLite.
-**
-**
-** This source file demonstrates how to use SQLite to create an SQL database 
-** server thread in a multiple-threaded program.  One or more client threads
-** send messages to the server thread and the server thread processes those
-** messages in the order received and returns the results to the client.
-**
-** One might ask:  "Why bother?  Why not just let each thread connect
-** to the database directly?"  There are a several of reasons to
-** prefer the client/server approach.
-**
-**    (1)  Some systems (ex: Redhat9) have broken threading implementations
-**         that prevent SQLite database connections from being used in
-**         a thread different from the one where they were created.  With
-**         the client/server approach, all database connections are created
-**         and used within the server thread.  Client calls to the database
-**         can be made from multiple threads (though not at the same time!)
-**
-**    (2)  Beginning with SQLite version 3.3.0, when two or more 
-**         connections to the same database occur within the same thread,
-**         they can optionally share their database cache.  This reduces
-**         I/O and memory requirements.  Cache shared is controlled using
-**         the sqlite3_enable_shared_cache() API.
-**
-**    (3)  Database connections on a shared cache use table-level locking
-**         instead of file-level locking for improved concurrency.
-**
-**    (4)  Database connections on a shared cache can by optionally
-**         set to READ UNCOMMITTED isolation.  (The default isolation for
-**         SQLite is SERIALIZABLE.)  When this occurs, readers will
-**         never be blocked by a writer and writers will not be
-**         blocked by readers.  There can still only be a single writer
-**         at a time, but multiple readers can simultaneously exist with
-**         that writer.  This is a huge increase in concurrency.
-**
-** To summarize the rational for using a client/server approach: prior
-** to SQLite version 3.3.0 it probably was not worth the trouble.  But
-** with SQLite version 3.3.0 and beyond you can get significant performance
-** and concurrency improvements and memory usage reductions by going
-** client/server.
-**
-** Note:  The extra features of version 3.3.0 described by points (2)
-** through (4) above are only available if you compile without the
-** option -DSQLITE_OMIT_SHARED_CACHE. 
-**
-** Here is how the client/server approach works:  The database server
-** thread is started on this procedure:
-**
-**       void *sqlite3_server(void *NotUsed);
-**
-** The sqlite_server procedure runs as long as the g.serverHalt variable
-** is false.  A mutex is used to make sure no more than one server runs
-** at a time.  The server waits for messages to arrive on a message
-** queue and processes the messages in order.
-**
-** Two convenience routines are provided for starting and stopping the
-** server thread:
-**
-**       void sqlite3_server_start(void);
-**       void sqlite3_server_stop(void);
-**
-** Both of the convenience routines return immediately.  Neither will
-** ever give an error.  If a server is already started or already halted,
-** then the routines are effectively no-ops.
-**
-** Clients use the following interfaces:
-**
-**       sqlite3_client_open
-**       sqlite3_client_prepare
-**       sqlite3_client_step
-**       sqlite3_client_reset
-**       sqlite3_client_finalize
-**       sqlite3_client_close
-**
-** These interfaces work exactly like the standard core SQLite interfaces
-** having the same names without the "_client_" infix.  Many other SQLite
-** interfaces can be used directly without having to send messages to the
-** server as long as SQLITE_ENABLE_MEMORY_MANAGEMENT is not defined.
-** The following interfaces fall into this second category:
-**
-**       sqlite3_bind_*
-**       sqlite3_changes
-**       sqlite3_clear_bindings
-**       sqlite3_column_*
-**       sqlite3_complete
-**       sqlite3_create_collation
-**       sqlite3_create_function
-**       sqlite3_data_count
-**       sqlite3_db_handle
-**       sqlite3_errcode
-**       sqlite3_errmsg
-**       sqlite3_last_insert_rowid
-**       sqlite3_total_changes
-**       sqlite3_transfer_bindings
-**
-** A single SQLite connection (an sqlite3* object) or an SQLite statement
-** (an sqlite3_stmt* object) should only be passed to a single interface
-** function at a time.  The connections and statements can be passed from
-** any thread to any of the functions listed in the second group above as
-** long as the same connection is not in use by two threads at once and
-** as long as SQLITE_ENABLE_MEMORY_MANAGEMENT is not defined.  Additional
-** information about the SQLITE_ENABLE_MEMORY_MANAGEMENT constraint is
-** below.
-**
-** The busy handler for all database connections should remain turned
-** off.  That means that any lock contention will cause the associated
-** sqlite3_client_step() call to return immediately with an SQLITE_BUSY
-** error code.  If a busy handler is enabled and lock contention occurs,
-** then the entire server thread will block.  This will cause not only
-** the requesting client to block but every other database client as
-** well.  It is possible to enhance the code below so that lock
-** contention will cause the message to be placed back on the top of
-** the queue to be tried again later.  But such enhanced processing is
-** not included here, in order to keep the example simple.
-**
-** This example code assumes the use of pthreads.  Pthreads
-** implementations are available for windows.  (See, for example
-** http://sourceware.org/pthreads-win32/announcement.html.)  Or, you
-** can translate the locking and thread synchronization code to use
-** windows primitives easily enough.  The details are left as an
-** exercise to the reader.
-**
-**** Restrictions Associated With SQLITE_ENABLE_MEMORY_MANAGEMENT ****
-**
-** If you compile with SQLITE_ENABLE_MEMORY_MANAGEMENT defined, then
-** SQLite includes code that tracks how much memory is being used by
-** each thread.  These memory counts can become confused if memory
-** is allocated by one thread and then freed by another.  For that
-** reason, when SQLITE_ENABLE_MEMORY_MANAGEMENT is used, all operations
-** that might allocate or free memory should be performanced in the same
-** thread that originally created the database connection.  In that case,
-** many of the operations that are listed above as safe to be performed
-** in separate threads would need to be sent over to the server to be
-** done there.  If SQLITE_ENABLE_MEMORY_MANAGEMENT is defined, then
-** the following functions can be used safely from different threads
-** without messing up the allocation counts:
-**
-**       sqlite3_bind_parameter_name
-**       sqlite3_bind_parameter_index
-**       sqlite3_changes
-**       sqlite3_column_blob
-**       sqlite3_column_count
-**       sqlite3_complete
-**       sqlite3_data_count
-**       sqlite3_db_handle
-**       sqlite3_errcode
-**       sqlite3_errmsg
-**       sqlite3_last_insert_rowid
-**       sqlite3_total_changes
-**
-** The remaining functions are not thread-safe when memory management
-** is enabled.  So one would have to define some new interface routines
-** along the following lines:
-**
-**       sqlite3_client_bind_*
-**       sqlite3_client_clear_bindings
-**       sqlite3_client_column_*
-**       sqlite3_client_create_collation
-**       sqlite3_client_create_function
-**       sqlite3_client_transfer_bindings
-**
-** The example code in this file is intended for use with memory
-** management turned off.  So the implementation of these additional
-** client interfaces is left as an exercise to the reader.
-**
-** It may seem surprising to the reader that the list of safe functions
-** above does not include things like sqlite3_bind_int() or
-** sqlite3_column_int().  But those routines might, in fact, allocate
-** or deallocate memory.  In the case of sqlite3_bind_int(), if the
-** parameter was previously bound to a string that string might need
-** to be deallocated before the new integer value is inserted.  In
-** the case of sqlite3_column_int(), the value of the column might be
-** a UTF-16 string which will need to be converted to UTF-8 then into
-** an integer.

-*************************************************************************
-**
-** OVERVIEW
-**
-**   This file contains experimental code used to record data from live
-**   SQLite applications that may be useful for offline analysis. 
-**   Specifically, this module can be used to capture the following
-**   information:
-**
-**     1) The initial contents of all database files opened by the 
-**        application, and
-**
-**     2) All SQL statements executed by the application.
-**
-**   The captured information can then be used to run (for example)
-**   performance analysis looking for slow queries or to look for
-**   optimization opportunities in either the application or in SQLite
-**   itself.
-**
-** USAGE
-**
-**   To use this module, SQLite must be compiled with the SQLITE_ENABLE_SQLLOG
-**   pre-processor symbol defined and this file linked into the application.
-**   One way to link this file into the application is to append the content
-**   of this file onto the end of the "sqlite3.c" amalgamation and then 
-**   recompile the application as normal except with the addition  of the
-**   -DSQLITE_ENABLE_SQLLOG option.
-**
-**   At runtime, logging is enabled by setting environment variable
-**   SQLITE_SQLLOG_DIR to the name of a directory in which to store logged 
-**   data. The logging directory must already exist.
-**
-**   Usually, if the application opens the same database file more than once
-**   (either by attaching it or by using more than one database handle), only
-**   a single copy is made. This behavior may be overridden (so that a 
-**   separate copy is taken each time the database file is opened or attached)
-**   by setting the environment variable SQLITE_SQLLOG_REUSE_FILES to 0.
-**
-**   If the environment variable SQLITE_SQLLOG_CONDITIONAL is defined, then
-**   logging is only done for database connections if a file named
-**   "<database>-sqllog" exists in the same directly as the main database
-**   file when it is first opened ("<database>" is replaced by the actual 
-**   name of the main database file).
-**
-** OUTPUT:
-**
-**   The SQLITE_SQLLOG_DIR is populated with three types of files:
-**
-**      sqllog_N.db   - Copies of database files. N may be any integer.
-**
-**      sqllog_N.sql  - A list of SQL statements executed by a single
-**                      connection. N may be any integer.
-**
-**      sqllog.idx    - An index mapping from integer N to a database
-**                      file name - indicating the full path of the
-**                      database from which sqllog_N.db was copied.
-**
-** ERROR HANDLING:
-**
-**   This module attempts to make a best effort to continue logging if an
-**   IO or other error is encountered. For example, if a log file cannot 
-**   be opened logs are not collected for that connection, but other
-**   logging proceeds as expected. Errors are logged by calling sqlite3_log().

-*************************************************************************
-**
-** The code in this file implements a Tcl interface used to test error
-** handling in the os_unix.c module. Wrapper functions that support fault
-** injection are registered as the low-level OS functions using the 
-** xSetSystemCall() method of the VFS. The Tcl interface is as follows:
-**
-**
-**   test_syscall install LIST
-**     Install wrapper functions for all system calls in argument LIST.
-**     LIST must be a list consisting of zero or more of the following
-**     literal values:
-**
-**         open        close      access   getcwd   stat      fstat    
-**         ftruncate   fcntl      read     pread    pread64   write
-**         pwrite      pwrite64   fchmod   fallocate mmap
-**
-**   test_syscall uninstall
-**     Uninstall all wrapper functions.
-**
-**   test_syscall fault ?COUNT PERSIST?
-**     If [test_syscall fault] is invoked without the two arguments, fault
-**     injection is disabled. Otherwise, fault injection is configured to
-**     cause a failure on the COUNT'th next call to a system call with a
-**     wrapper function installed. A COUNT value of 1 means fail the next
-**     system call. 
-** 
-**     Argument PERSIST is interpreted as a boolean. If true, the all
-**     system calls following the initial failure also fail. Otherwise, only
-**     the single transient failure is injected.
-**
-**   test_syscall errno CALL ERRNO
-**     Set the value that the global "errno" is set to following a fault
-**     in call CALL. Argument CALL must be one of the system call names
-**     listed above (under [test_syscall install]). ERRNO is a symbolic
-**     name (i.e. "EACCES"). Not all errno codes are supported. Add extra
-**     to the aErrno table in function test_syscall_errno() below as 
-**     required.
-**
-**   test_syscall reset ?SYSTEM-CALL?
-**     With no argument, this is an alias for the [uninstall] command. However,
-**     this command uses a VFS call of the form:
-**
-**       xSetSystemCall(pVfs, 0, 0);
-**
-**     To restore the default system calls. The [uninstall] command restores
-**     each system call individually by calling (i.e.):
-**
-**       xSetSystemCall(pVfs, "open", 0);
-**
-**     With an argument, this command attempts to reset the system call named
-**     by the parameter using the same method as [uninstall].
-**
-**   test_syscall exists SYSTEM-CALL
-**     Return true if the named system call exists. Or false otherwise.
-**
-**   test_syscall list
-**     Return a list of all system calls. The list is constructed using
-**     the xNextSystemCall() VFS method.
-**
-**   test_syscall pagesize PGSZ
-**     If PGSZ is a power of two greater than 256, install a wrapper around
-**     OS function getpagesize() that reports the system page size as PGSZ.
-**     Or, if PGSZ is less than zero, remove any wrapper already installed.

-** The author disclaims copyright to this source code.  In place of
-** a legal notice, here is a blessing:

-*************************************************************************
-** Code for testing the virtual table interfaces.  This code
-** is not included in the SQLite library.  It is used for automated
-** testing of the SQLite library.
-**
-** The emphasis of this file is a virtual table that provides
-** access to TCL variables.
-**
-** The TCLVAR eponymous virtual table has a schema like this:
-**
-**    CREATE TABLE tclvar(
-**       name TEXT,       -- base name of the variable:  "x" in "$x(y)"
-**       arrayname TEXT,  -- array index name: "y" in "$x(y)"
-**       value TEXT,      -- the value of the variable 
-**       fullname TEXT,   -- the full name of the variable
-**       PRIMARY KEY(fullname)
-**    ) WITHOUT ROWID;
-**
-** DELETE, INSERT, and UPDATE operations use the "fullname" field to
-** determine the variable to be modified.  Changing "value" to NULL
-** deletes the variable.
-**
-** For SELECT operations, the "name" and "arrayname" fields will always
-** match the "fullname" field.  For DELETE, INSERT, and UPDATE, the
-** "name" and "arrayname" fields are ignored and the variable is modified
-** according to "fullname" and "value" only.

-** Whenever the xShmMap method of the VFS
-** is invoked, the SCRIPT is executed as follows:
-**
-**   SCRIPT xShmMap    FILENAME ID
-**
-** The value returned by the invocation of SCRIPT above is interpreted as
-** an SQLite error code and returned to SQLite. Either a symbolic 
-** "SQLITE_OK" or numeric "0" value may be returned.
-**
-** The contents of the shared-memory buffer associated with a given file
-** may be read and set using the following command:
-**
-**   VFSNAME shm FILENAME ?NEWVALUE?

-** a legal notice, here is a blessing:

-******************************************************************************
-**
-** This file contains code implements a VFS shim that writes diagnostic
-** output for each VFS call, similar to "strace".
-**
-** USAGE:
-**
-** This source file exports a single symbol which is the name of a
-** function:
-**
-**   int vfstrace_register(
-**     const char *zTraceName,         // Name of the newly constructed VFS
-**     const char *zOldVfsName,        // Name of the underlying VFS
-**     int (*xOut)(const char*,void*), // Output routine.  ex: fputs
-**     void *pOutArg,                  // 2nd argument to xOut.  ex: stderr
-**     int makeDefault                 // Make the new VFS the default
-**   );
-**
-** Applications that want to trace their VFS usage must provide a callback
-** function with this prototype:
-**
-**   int traceOutput(const char *zMessage, void *pAppData);
-**
-** This function will "output" the trace messages, where "output" can
-** mean different things to different applications.  The traceOutput function
-** for the command-line shell (see shell.c) is "fputs" from the standard
-** library, which means that all trace output is written on the stream
-** specified by the second argument.  In the case of the command-line shell
-** the second argument is stderr.  Other applications might choose to output
-** trace information to a file, over a socket, or write it into a buffer.
-**
-** The vfstrace_register() function creates a new "shim" VFS named by
-** the zTraceName parameter.  A "shim" VFS is an SQLite backend that does
-** not really perform the duties of a true backend, but simply filters or
-** interprets VFS calls before passing them off to another VFS which does
-** the actual work.  In this case the other VFS - the one that does the
-** real work - is identified by the second parameter, zOldVfsName.  If
-** the 2nd parameter is NULL then the default VFS is used.  The common
-** case is for the 2nd parameter to be NULL.
-**
-** The third and fourth parameters are the pointer to the output function
-** and the second argument to the output function.  For the SQLite
-** command-line shell, when the -vfstrace option is used, these parameters
-** are fputs and stderr, respectively.
-**
-** The fifth argument is true (non-zero) to cause the newly created VFS
-** to become the default VFS.  The common case is for the fifth parameter
-** to be true.
-**
-** The call to vfstrace_register() simply creates the shim VFS that does
-** tracing.  The application must also arrange to use the new VFS for
-** all database connections that are created and for which tracing is 
-** desired.  This can be done by specifying the trace VFS using URI filename
-** notation, or by specifying the trace VFS as the 4th parameter to
-** sqlite3_open_v2() or by making the trace VFS be the default (by setting
-** the 5th parameter of vfstrace_register() to 1).
-**
-**
-** ENABLING VFSTRACE IN A COMMAND-LINE SHELL
-**
-** The SQLite command line shell implemented by the shell.c source file
-** can be used with this module.  To compile in -vfstrace support, first
-** gather this file (test_vfstrace.c), the shell source file (shell.c),
-** and the SQLite amalgamation source files (sqlite3.c, sqlite3.h) into
-** the working directory.  Then compile using a command like the following:
-**
-**    gcc -o sqlite3 -Os -I. -DSQLITE_ENABLE_VFSTRACE \
-**        -DSQLITE_THREADSAFE=0 -DSQLITE_ENABLE_FTS3 -DSQLITE_ENABLE_RTREE \
-**        -DHAVE_READLINE -DHAVE_USLEEP=1 \
-**        shell.c test_vfstrace.c sqlite3.c -ldl -lreadline -lncurses
-**
-** The gcc command above works on Linux and provides (in addition to the
-** -vfstrace option) support for FTS3 and FTS4, RTREE, and command-line
-** editing using the readline library.  The command-line shell does not
-** use threads so we added -DSQLITE_THREADSAFE=0 just to make the code
-** run a little faster.   For compiling on a Mac, you'll probably need
-** to omit the -DHAVE_READLINE, the -lreadline, and the -lncurses options.
-** The compilation could be simplified to just this:
-**
-**    gcc -DSQLITE_ENABLE_VFSTRACE \
-**         shell.c test_vfstrace.c sqlite3.c -ldl -lpthread
-**
-** In this second example, all unnecessary options have been removed
-** Note that since the code is now threadsafe, we had to add the -lpthread
-** option to pull in the pthreads library.
-**
-** To cross-compile for windows using MinGW, a command like this might
-** work:
-**
-**    /opt/mingw/bin/i386-mingw32msvc-gcc -o sqlite3.exe -Os -I \
-**         -DSQLITE_THREADSAFE=0 -DSQLITE_ENABLE_VFSTRACE \
-**         shell.c test_vfstrace.c sqlite3.c
-**
-** Similar compiler commands will work on different systems.  The key
-** invariants are (1) you must have -DSQLITE_ENABLE_VFSTRACE so that
-** the shell.c source file will know to include the -vfstrace command-line
-** option and (2) you must compile and link the three source files
-** shell,c, test_vfstrace.c, and sqlite3.c.

-** The most recently coded instruction was an OP_Column to retrieve the
-** i-th column of table pTab. This routine sets the P4 parameter of the 
-** OP_Column to the default value, if any.
-**
-** The default value of a column is specified by a DEFAULT clause in the 
-** column definition. This was either supplied by the user when the table
-** was created, or added later to the table definition by an ALTER TABLE
-** command. If the latter, then the row-records in the table btree on disk
-** may not contain a value for the column and the default value, taken
-** from the P4 parameter of the OP_Column instruction, is returned instead.
-** If the former, then all row-records are guaranteed to include a value
-** for the column and the P4 value is not required.
-**
-** Column definitions created by an ALTER TABLE command may only have 
-** literal default values specified: a number, null or a string. (If a more
-** complicated default expression value was provided, it is evaluated 
-** when the ALTER TABLE is executed and one of the literal values written
-** into the sqlite_master table.)
-**
-** Therefore, the P4 parameter is only required if the default value for
-** the column is a literal number, string or null. The sqlite3ValueFromExpr()
-** function is capable of transforming these types of expressions into
-** sqlite3_value objects.
-**
-** If parameter iReg is not negative, code an OP_RealAffinity instruction
-** on register iReg. This is used when an equivalent integer value is 
-** stored in place of an 8-byte floating point value in order to save 
-** space.

-** Notes On Invalid UTF-8:
-**
-**  *  This routine never allows a 7-bit character (0x00 through 0x7f) to
-**     be encoded as a multi-byte character.  Any multi-byte character that
-**     attempts to encode a value between 0x00 and 0x7f is rendered as 0xfffd.
-**
-**  *  This routine never allows a UTF16 surrogate value to be encoded.
-**     If a multi-byte character attempts to encode a value between
-**     0xd800 and 0xe000 then it is rendered as 0xfffd.
-**
-**  *  Bytes in the range of 0x80 through 0xbf which occur as the first
-**     byte of a character are interpreted as single-byte characters
-**     and rendered as themselves even though they are technically
-**     invalid characters.
-**
-**  *  This routine accepts over-length UTF8 encodings
-**     for unicode values 0x80 and greater.  It does not change over-length
-**     encodings to 0xfffd as some systems recommend.

-** The VACUUM command is used to clean up the database,
-** collapse free space, etc.  It is modelled after the VACUUM command
-** in PostgreSQL.  The VACUUM command works as follows:
-**
-**   (1)  Create a new transient database file
-**   (2)  Copy all content from the database being vacuumed into
-**        the new transient database file
-**   (3)  Copy content from the transient database back into the
-**        original database.
-**
-** The transient database requires temporary disk space approximately
-** equal to the size of the original database.  The copy operation of
-** step (3) requires additional temporary disk space approximately equal
-** to the size of the original database for the rollback journal.
-** Hence, temporary disk space that is approximately 2x the size of the
-** original database is required.  Every page of the database is written
-** approximately 3 times:  Once for step (2) and twice for step (3).
-** Two writes per page are required in step (3) because the original
-** database content must be written into the rollback journal prior to
-** overwriting the database with the vacuumed content.
-**
-** Only 1x temporary space and only 1x writes would be required if
-** the copy of step (3) were replaced by deleting the original database
-** and renaming the transient database as the original.  But that will
-** not work if other processes are attached to the original database.
-** And a power loss in between deleting the original and renaming the
-** transient would cause the database file to appear to be deleted
-** following reboot.

-** What follows is a massive switch statement where each case implements a
-** separate instruction in the virtual machine.  If we follow the usual
-** indentation conventions, each case should be indented by 6 spaces.  But
-** that is a lot of wasted space on the left margin.  So the code within
-** the switch statement will break with convention and be flush-left. Another
-** big comment (similar to this one) will mark the point in the code where
-** we transition back to normal indentation.
-**
-** The formatting of each case is important.  The makefile for SQLite
-** generates two C files "opcodes.h" and "opcodes.c" by scanning this
-** file looking for lines that begin with "case OP_".  The opcodes.h files
-** will be filled with #defines that give unique integer values to each
-** opcode and the opcodes.c file is filled with an array of strings where
-** each string is the symbolic name for the corresponding opcode.  If the
-** case statement is followed by a comment of the form "/# same as ... #/"
-** that comment is used to determine the particular value of the opcode.
-**
-** Other keywords in the comment that follows each case are used to
-** construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
-** Keywords include: in1, in2, in3, out2, out3.  See
-** the mkopcodeh.awk script for additional information.
-**
-** Documentation about VDBE opcodes is generated by scanning this file
-** for lines of that contain "Opcode:".  That line and all subsequent
-** comment lines are used in the generation of the opcode.html documentation
-** file.

-** The following functions:

-** sqlite3VdbeSerialTypeLen()

-** sqlite3VdbeSerialPut()
-** sqlite3VdbeSerialGet()
-**
-** encapsulate the code that serializes values for storage in SQLite
-** data and index records. Each serialized value consists of a
-** 'serial-type' and a blob of data. The serial type is an 8-byte unsigned
-** integer, stored as a varint.
-**
-** In an SQLite index record, the serial type is stored directly before
-** the blob of data that it corresponds to. In a table record, all serial
-** types are stored at the start of the record, and the blobs of data at
-** the end. Hence these functions allow the caller to handle the
-** serial-type and data blob separately.
-**
-** The following table describes the various storage classes for data:

-**
-** (later):  It is reported to me that the mixed-endian problem

-** that early versions of GCC stored the two words of a 64-bit
-** float in the wrong order.  And that error has been propagated

-** GCC might have just copying the problem from a prior compiler.
-** I am also told that newer versions of GCC that follow a different
-** ABI get the byte order right.
-**
-** Developers using SQLite on an ARM7 should compile and run their
-** application using -DSQLITE_DEBUG=1 at least once.  With DEBUG
-** enabled, some asserts below will ensure that the byte order of
-** floating point values is correct.
-**
-** (2007-08-30)  Frank van Vugt has studied this problem closely

-** writes that some Linux kernels offer floating point hardware
-** emulation that uses only 32-bit mantissas instead of a full 
-** 48-bits as required by the IEEE standard.  (This is the
-** CONFIG_FPE_FASTFPE option.)  On such systems, floating point
-** byte swapping becomes very complicated.  To avoid problems,
-** the necessary byte swapping is carried out using a 64-bit integer
-** rather than a 64-bit float.  Frank assures us that the code here
-** works for him.  We, the developers, have no way to independently
-** verify this, but Frank seems to know what he is talking about
-** so we trust him.

-*************************************************************************
-** This file contains code for the VdbeSorter object, used in concert with
-** a VdbeCursor to sort large numbers of keys for CREATE INDEX statements
-** or by SELECT statements with ORDER BY clauses that cannot be satisfied
-** using indexes and without LIMIT clauses.
-**
-** The VdbeSorter object implements a multi-threaded external merge sort
-** algorithm that is efficient even if the number of elements being sorted
-** exceeds the available memory.
-**
-** Here is the (internal, non-API) interface between this module and the
-** rest of the SQLite system:
-**
-**    sqlite3VdbeSorterInit()       Create a new VdbeSorter object.
-**
-**    sqlite3VdbeSorterWrite()      Add a single new row to the VdbeSorter
-**                                  object.  The row is a binary blob in the
-**                                  OP_MakeRecord format that contains both
-**                                  the ORDER BY key columns and result columns
-**                                  in the case of a SELECT w/ ORDER BY, or
-**                                  the complete record for an index entry
-**                                  in the case of a CREATE INDEX.
-**
-**    sqlite3VdbeSorterRewind()     Sort all content previously added.
-**                                  Position the read cursor on the
-**                                  first sorted element.
-**
-**    sqlite3VdbeSorterNext()       Advance the read cursor to the next sorted
-**                                  element.
-**
-**    sqlite3VdbeSorterRowkey()     Return the complete binary blob for the
-**                                  row currently under the read cursor.
-**
-**    sqlite3VdbeSorterCompare()    Compare the binary blob for the row
-**                                  currently under the read cursor against
-**                                  another binary blob X and report if
-**                                  X is strictly less than the read cursor.
-**                                  Used to enforce uniqueness in a
-**                                  CREATE UNIQUE INDEX statement.
-**
-**    sqlite3VdbeSorterClose()      Close the VdbeSorter object and reclaim
-**                                  all resources.
-**
-**    sqlite3VdbeSorterReset()      Refurbish the VdbeSorter for reuse.  This
-**                                  is like Close() followed by Init() only
-**                                  much faster.
-**
-** The interfaces above must be called in a particular order.  Write() can 
-** only occur in between Init()/Reset() and Rewind().  Next(), Rowkey(), and
-** Compare() can only occur in between Rewind() and Close()/Reset(). i.e.
-**
-**   Init()
-**   for each record: Write()
-**   Rewind()
-**     Rowkey()/Compare()
-**   Next() 
-**   Close()
-**
-** Algorithm:
-**
-** Records passed to the sorter via calls to Write() are initially held 
-** unsorted in main memory. Assuming the amount of memory used never exceeds
-** a threshold, when Rewind() is called the set of records is sorted using
-** an in-memory merge sort. In this case, no temporary files are required
-** and subsequent calls to Rowkey(), Next() and Compare() read records 
-** directly from main memory.
-**
-** If the amount of space used to store records in main memory exceeds the
-** threshold, then the set of records currently in memory are sorted and
-** written to a temporary file in "Packed Memory Array" (PMA) format.
-** A PMA created at this point is known as a "level-0 PMA". Higher levels
-** of PMAs may be created by merging existing PMAs together - for example
-** merging two or more level-0 PMAs together creates a level-1 PMA.
-**
-** The threshold for the amount of main memory to use before flushing 
-** records to a PMA is roughly the same as the limit configured for the
-** page-cache of the main database. Specifically, the threshold is set to 
-** the value returned by "PRAGMA main.page_size" multipled by 
-** that returned by "PRAGMA main.cache_size", in bytes.
-**
-** If the sorter is running in single-threaded mode, then all PMAs generated
-** are appended to a single temporary file. Or, if the sorter is running in
-** multi-threaded mode then up to (N+1) temporary files may be opened, where
-** N is the configured number of worker threads. In this case, instead of
-** sorting the records and writing the PMA to a temporary file itself, the
-** calling thread usually launches a worker thread to do so. Except, if
-** there are already N worker threads running, the main thread does the work
-** itself.
-**
-** The sorter is running in multi-threaded mode if (a) the library was built
-** with pre-processor symbol SQLITE_MAX_WORKER_THREADS set to a value greater
-** than zero, and (b) worker threads have been enabled at runtime by calling
-** "PRAGMA threads=N" with some value of N greater than 0.
-**
-** When Rewind() is called, any data remaining in memory is flushed to a 
-** final PMA. So at this point the data is stored in some number of sorted
-** PMAs within temporary files on disk.
-**
-** If there are fewer than SORTER_MAX_MERGE_COUNT PMAs in total and the
-** sorter is running in single-threaded mode, then these PMAs are merged
-** incrementally as keys are retreived from the sorter by the VDBE.  The
-** MergeEngine object, described in further detail below, performs this
-** merge.
-**
-** Or, if running in multi-threaded mode, then a background thread is
-** launched to merge the existing PMAs. Once the background thread has
-** merged T bytes of data into a single sorted PMA, the main thread 
-** begins reading keys from that PMA while the background thread proceeds
-** with merging the next T bytes of data. And so on.
-**
-** Parameter T is set to half the value of the memory threshold used 
-** by Write() above to determine when to create a new PMA.
-**
-** If there are more than SORTER_MAX_MERGE_COUNT PMAs in total when 
-** Rewind() is called, then a hierarchy of incremental-merges is used. 
-** First, T bytes of data from the first SORTER_MAX_MERGE_COUNT PMAs on 
-** disk are merged together. Then T bytes of data from the second set, and
-** so on, such that no operation ever merges more than SORTER_MAX_MERGE_COUNT
-** PMAs at a time. This done is to improve locality.
-**
-** If running in multi-threaded mode and there are more than
-** SORTER_MAX_MERGE_COUNT PMAs on disk when Rewind() is called, then more
-** than one background thread may be created. Specifically, there may be
-** one background thread for each temporary file on disk, and one background
-** thread to merge the output of each of the others to a single PMA for
-** the main thread to read from.

-**
-** The aReadr[] array contains a PmaReader object for each of the PMAs being
-** merged.  An aReadr[] object either points to a valid key or else is at EOF.
-** ("EOF" means "End Of File".  When aReadr[] is at EOF there is no more data.)
-** For the purposes of the paragraphs below, we assume that the array is
-** actually N elements in size, where N is the smallest power of 2 greater
-** to or equal to the number of PMAs being merged. The extra aReadr[] elements
-** are treated as if they are empty (always at EOF).
-**
-** The aTree[] array is also N elements in size. The value of N is stored in
-** the MergeEngine.nTree variable.
-**
-** The final (N/2) elements of aTree[] contain the results of comparing
-** pairs of PMA keys together. Element i contains the result of 
-** comparing aReadr[2*i-N] and aReadr[2*i-N+1]. Whichever key is smaller, the
-** aTree element is set to the index of it. 
-**
-** For the purposes of this comparison, EOF is considered greater than any
-** other key value. If the keys are equal (only possible with two EOF
-** values), it doesn't matter which index is stored.
-**
-** The (N/4) elements of aTree[] that precede the final (N/2) described 
-** above contains the index of the smallest of each block of 4 PmaReaders
-** And so on. So that aTree[1] contains the index of the PmaReader that 
-** currently points to the smallest key value. aTree[0] is unused.
-**
-** Example:
-**
-**     aReadr[0] -> Banana
-**     aReadr[1] -> Feijoa
-**     aReadr[2] -> Elderberry
-**     aReadr[3] -> Currant
-**     aReadr[4] -> Grapefruit
-**     aReadr[5] -> Apple
-**     aReadr[6] -> Durian
-**     aReadr[7] -> EOF
-**
-**     aTree[] = { X, 5   0, 5    0, 3, 5, 6 }
-**
-** The current element is "Apple" (the value of the key indicated by 
-** PmaReader 5). When the Next() operation is invoked, PmaReader 5 will
-** be advanced to the next key in its segment. Say the next key is
-** "Eggplant":
-**
-**     aReadr[5] -> Eggplant
-**
-** The contents of aTree[] are updated first by comparing the new PmaReader
-** 5 key to the current key of PmaReader 4 (still "Grapefruit"). The PmaReader
-** 5 value is still smaller, so aTree[6] is set to 5. And so on up the tree.
-** The value of PmaReader 6 - "Durian" - is now smaller than that of PmaReader
-** 5, so aTree[3] is set to 6. Key 0 is smaller than key 6 (Banana<Durian),
-** so the value written into element 1 of the array is 0. As follows:
-**
-**     aTree[] = { X, 0   0, 6    0, 3, 5, 6 }
-**
-** In other words, each time we advance to the next sorter element, log2(N)
-** key comparison operations are required, where N is the number of segments
-** being merged (rounded up to the next power of 2).

-** Normally, a PmaReader object iterates through an existing PMA stored

-** an object of the following type, it may be used to iterate/merge through
-** multiple PMAs simultaneously.
-**
-** There are two types of IncrMerger object - single (bUseThread==0) and 
-** multi-threaded (bUseThread==1). 
-**
-** A multi-threaded IncrMerger object uses two temporary files - aFile[0] 
-** and aFile[1]. Neither file is allowed to grow to more than mxSz bytes in 
-** size. When the IncrMerger is initialized, it reads enough data from 
-** pMerger to populate aFile[0]. It then sets variables within the 
-** corresponding PmaReader object to read from that file and kicks off 
-** a background thread to populate aFile[1] with the next mxSz bytes of 
-** sorted record data from pMerger. 
-**
-** When the PmaReader reaches the end of aFile[0], it blocks until the
-** background thread has finished populating aFile[1]. It then exchanges
-** the contents of the aFile[0] and aFile[1] variables within this structure,
-** sets the PmaReader fields to read from the new aFile[0] and kicks off
-** another background thread to populate the new aFile[1]. And so on, until
-** the contents of pMerger are exhausted.
-**
-** A single-threaded IncrMerger does not open any temporary files of its
-** own. Instead, it has exclusive access to mxSz bytes of space beginning
-** at offset iStartOff of file pTask->file2. And instead of using a 
-** background thread to prepare data for the PmaReader, with a single
-** threaded IncrMerger the allocate part of pTask->file2 is "refilled" with
-** keys from pMerger by the calling thread whenever the PmaReader runs out
-** of data.

-*************************************************************************
-**
-** This file contains the implementation of a write-ahead log (WAL) used in 
-** "journal_mode=WAL" mode.
-**
-** WRITE-AHEAD LOG (WAL) FILE FORMAT
-**
-** A WAL file consists of a header followed by zero or more "frames".
-** Each frame records the revised content of a single page from the
-** database file.  All changes to the database are recorded by writing
-** frames into the WAL.  Transactions commit when a frame is written that
-** contains a commit marker.  A single WAL can and usually does record 
-** multiple transactions.  Periodically, the content of the WAL is
-** transferred back into the database file in an operation called a
-** "checkpoint".
-**
-** A single WAL file can be used multiple times.  In other words, the
-** WAL can fill up with frames and then be checkpointed and then new
-** frames can overwrite the old ones.  A WAL always grows from beginning
-** toward the end.  Checksums and counters attached to each frame are
-** used to determine which frames within the WAL are valid and which
-** are leftovers from prior checkpoints.
-**
-** The WAL header is 32 bytes in size and consists of the following eight
-** big-endian 32-bit unsigned integer values:
-**
-**     0: Magic number.  0x377f0682 or 0x377f0683
-**     4: File format version.  Currently 3007000
-**     8: Database page size.  Example: 1024
-**    12: Checkpoint sequence number
-**    16: Salt-1, random integer incremented with each checkpoint
-**    20: Salt-2, a different random integer changing with each ckpt
-**    24: Checksum-1 (first part of checksum for first 24 bytes of header).
-**    28: Checksum-2 (second part of checksum for first 24 bytes of header).
-**
-** Immediately following the wal-header are zero or more frames. Each
-** frame consists of a 24-byte frame-header followed by a <page-size> bytes
-** of page data. The frame-header is six big-endian 32-bit unsigned 
-** integer values, as follows:
-**
-**     0: Page number.
-**     4: For commit records, the size of the database image in pages 
-**        after the commit. For all other records, zero.
-**     8: Salt-1 (copied from the header)
-**    12: Salt-2 (copied from the header)
-**    16: Checksum-1.
-**    20: Checksum-2.
-**
-** A frame is considered valid if and only if the following conditions are
-** true:
-**
-**    (1) The salt-1 and salt-2 values in the frame-header match
-**        salt values in the wal-header
-**
-**    (2) The checksum values in the final 8 bytes of the frame-header
-**        exactly match the checksum computed consecutively on the
-**        WAL header and the first 8 bytes and the content of all frames
-**        up to and including the current frame.
-**
-** The checksum is computed using 32-bit big-endian integers if the
-** magic number in the first 4 bytes of the WAL is 0x377f0683 and it
-** is computed using little-endian if the magic number is 0x377f0682.
-** The checksum values are always stored in the frame header in a
-** big-endian format regardless of which byte order is used to compute
-** the checksum.  The checksum is computed by interpreting the input as
-** an even number of unsigned 32-bit integers: x[0] through x[N].  The
-** algorithm used for the checksum is as follows:
-** 
-**   for i from 0 to n-1 step 2:
-**     s0 += x[i] + s1;
-**     s1 += x[i+1] + s0;
-**   endfor
-**
-** Note that s0 and s1 are both weighted checksums using fibonacci weights
-** in reverse order (the largest fibonacci weight occurs on the first element
-** of the sequence being summed.)  The s1 value spans all 32-bit 
-** terms of the sequence whereas s0 omits the final term.
-**
-** On a checkpoint, the WAL is first VFS.xSync-ed, then valid content of the
-** WAL is transferred into the database, then the database is VFS.xSync-ed.
-** The VFS.xSync operations serve as write barriers - all writes launched
-** before the xSync must complete before any write that launches after the
-** xSync begins.
-**
-** After each checkpoint, the salt-1 value is incremented and the salt-2
-** value is randomized.  This prevents old and new frames in the WAL from
-** being considered valid at the same time and being checkpointing together
-** following a crash.
-**
-** READER ALGORITHM
-**
-** To read a page from the database (call it page number P), a reader
-** first checks the WAL to see if it contains page P.  If so, then the
-** last valid instance of page P that is a followed by a commit frame
-** or is a commit frame itself becomes the value read.  If the WAL
-** contains no copies of page P that are valid and which are a commit
-** frame or are followed by a commit frame, then page P is read from
-** the database file.
-**
-** To start a read transaction, the reader records the index of the last
-** valid frame in the WAL.  The reader uses this recorded "mxFrame" value
-** for all subsequent read operations.  New transactions can be appended
-** to the WAL, but as long as the reader uses its original mxFrame value
-** and ignores the newly appended content, it will see a consistent snapshot
-** of the database from a single point in time.  This technique allows
-** multiple concurrent readers to view different versions of the database
-** content simultaneously.
-**
-** The reader algorithm in the previous paragraphs works correctly, but 
-** because frames for page P can appear anywhere within the WAL, the
-** reader has to scan the entire WAL looking for page P frames.  If the
-** WAL is large (multiple megabytes is typical) that scan can be slow,
-** and read performance suffers.  To overcome this problem, a separate
-** data structure called the wal-index is maintained to expedite the
-** search for frames of a particular page.
-** 
-** WAL-INDEX FORMAT
-**
-** Conceptually, the wal-index is shared memory, though VFS implementations
-** might choose to implement the wal-index using a mmapped file.  Because
-** the wal-index is shared memory, SQLite does not support journal_mode=WAL 
-** on a network filesystem.  All users of the database must be able to
-** share memory.
-**
-** In the default unix and windows implementation, the wal-index is a mmapped
-** file whose name is the database name with a "-shm" suffix added.  For that
-** reason, the wal-index is sometimes called the "shm" file.
-**
-** The wal-index is transient.  After a crash, the wal-index can (and should
-** be) reconstructed from the original WAL file.  In fact, the VFS is required
-** to either truncate or zero the header of the wal-index when the last
-** connection to it closes.  Because the wal-index is transient, it can
-** use an architecture-specific format; it does not have to be cross-platform.
-** Hence, unlike the database and WAL file formats which store all values
-** as big endian, the wal-index can store multi-byte values in the native
-** byte order of the host computer.
-**
-** The purpose of the wal-index is to answer this question quickly:  Given
-** a page number P and a maximum frame index M, return the index of the 
-** last frame in the wal before frame M for page P in the WAL, or return
-** NULL if there are no frames for page P in the WAL prior to M.
-**
-** The wal-index consists of a header region, followed by an one or
-** more index blocks.  
-**
-** The wal-index header contains the total number of frames within the WAL
-** in the mxFrame field.
-**
-** Each index block except for the first contains information on 
-** HASHTABLE_NPAGE frames. The first index block contains information on
-** HASHTABLE_NPAGE_ONE frames. The values of HASHTABLE_NPAGE_ONE and 
-** HASHTABLE_NPAGE are selected so that together the wal-index header and
-** first index block are the same size as all other index blocks in the
-** wal-index.
-**
-** Each index block contains two sections, a page-mapping that contains the
-** database page number associated with each wal frame, and a hash-table 
-** that allows readers to query an index block for a specific page number.
-** The page-mapping is an array of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE
-** for the first index block) 32-bit page numbers. The first entry in the 
-** first index-block contains the database page number corresponding to the
-** first frame in the WAL file. The first entry in the second index block
-** in the WAL file corresponds to the (HASHTABLE_NPAGE_ONE+1)th frame in
-** the log, and so on.
-**
-** The last index block in a wal-index usually contains less than the full
-** complement of HASHTABLE_NPAGE (or HASHTABLE_NPAGE_ONE) page-numbers,
-** depending on the contents of the WAL file. This does not change the
-** allocated size of the page-mapping array - the page-mapping array merely
-** contains unused entries.
-**
-** Even without using the hash table, the last frame for page P
-** can be found by scanning the page-mapping sections of each index block
-** starting with the last index block and moving toward the first, and
-** within each index block, starting at the end and moving toward the
-** beginning.  The first entry that equals P corresponds to the frame
-** holding the content for that page.
-**
-** The hash table consists of HASHTABLE_NSLOT 16-bit unsigned integers.
-** HASHTABLE_NSLOT = 2*HASHTABLE_NPAGE, and there is one entry in the
-** hash table for each page number in the mapping section, so the hash 
-** table is never more than half full.  The expected number of collisions 
-** prior to finding a match is 1.  Each entry of the hash table is an
-** 1-based index of an entry in the mapping section of the same
-** index block.   Let K be the 1-based index of the largest entry in
-** the mapping section.  (For index blocks other than the last, K will
-** always be exactly HASHTABLE_NPAGE (4096) and for the last index block
-** K will be (mxFrame%HASHTABLE_NPAGE).)  Unused slots of the hash table
-** contain a value of 0.
-**
-** To look for page P in the hash table, first compute a hash iKey on
-** P as follows:
-**
-**      iKey = (P * 383) % HASHTABLE_NSLOT
-**
-** Then start scanning entries of the hash table, starting with iKey
-** (wrapping around to the beginning when the end of the hash table is
-** reached) until an unused hash slot is found. Let the first unused slot
-** be at index iUnused.  (iUnused might be less than iKey if there was
-** wrap-around.) Because the hash table is never more than half full,
-** the search is guaranteed to eventually hit an unused entry.  Let 
-** iMax be the value between iKey and iUnused, closest to iUnused,
-** where aHash[iMax]==P.  If there is no iMax entry (if there exists
-** no hash slot such that aHash[i]==p) then page P is not in the
-** current index block.  Otherwise the iMax-th mapping entry of the
-** current index block corresponds to the last entry that references 
-** page P.
-**
-** A hash search begins with the last index block and moves toward the
-** first index block, looking for entries corresponding to page P.  On
-** average, only two or three slots in each index block need to be
-** examined in order to either find the last entry for page P, or to
-** establish that no such entry exists in the block.  Each index block
-** holds over 4000 entries.  So two or three index blocks are sufficient
-** to cover a typical 10 megabyte WAL file, assuming 1K pages.  8 or 10
-** comparisons (on average) suffice to either locate a frame in the
-** WAL or to establish that the frame does not exist in the WAL.  This
-** is much faster than scanning the entire 10MB WAL.
-**
-** Note that entries are added in order of increasing K.  Hence, one
-** reader might be using some value K0 and a second reader that started
-** at a later time (after additional transactions were added to the WAL
-** and to the wal-index) might be using a different value K1, where K1>K0.
-** Both readers can use the same hash table and mapping section to get
-** the correct result.  There may be entries in the hash table with
-** K>K0 but to the first reader, those entries will appear to be unused
-** slots in the hash table and so the first reader will get an answer as
-** if no values greater than K0 had ever been inserted into the hash table
-** in the first place - which is what reader one wants.  Meanwhile, the
-** second reader using K1 will see additional values that were inserted
-** later, which is exactly what reader two wants.  
-**
-** When a rollback occurs, the value of K is decreased. Hash table entries
-** that correspond to frames greater than the new K value are removed
-** from the hash table at this point.

-** A copy of the following object occurs in the wal-index immediately
-** following the second copy of the WalIndexHdr.  This object stores
-** information used by checkpoint.
-**
-** nBackfill is the number of frames in the WAL that have been written
-** back into the database. (We call the act of moving content from WAL to
-** database "backfilling".)  The nBackfill number is never greater than
-** WalIndexHdr.mxFrame.  nBackfill can only be increased by threads
-** holding the WAL_CKPT_LOCK lock (which includes a recovery thread).
-** However, a WAL_WRITE_LOCK thread can move the value of nBackfill from
-** mxFrame back to zero when the WAL is reset.
-**
-** nBackfillAttempted is the largest value of nBackfill that a checkpoint
-** has attempted to achieve.  Normally nBackfill==nBackfillAtempted, however
-** the nBackfillAttempted is set before any backfilling is done and the
-** nBackfill is only set after all backfilling completes.  So if a checkpoint
-** crashes, nBackfillAttempted might be larger than nBackfill.  The
-** WalIndexHdr.mxFrame must never be less than nBackfillAttempted.
-**
-** The aLock[] field is a set of bytes used for locking.  These bytes should
-** never be read or written.
-**
-** There is one entry in aReadMark[] for each reader lock.  If a reader
-** holds read-lock K, then the value in aReadMark[K] is no greater than
-** the mxFrame for that reader.  The value READMARK_NOT_USED (0xffffffff)
-** for any aReadMark[] means that entry is unused.  aReadMark[0] is 
-** a special case; its value is never used and it exists as a place-holder
-** to avoid having to offset aReadMark[] indexs by one.  Readers holding
-** WAL_READ_LOCK(0) always ignore the entire WAL and read all content
-** directly from the database.
-**
-** The value of aReadMark[K] may only be changed by a thread that
-** is holding an exclusive lock on WAL_READ_LOCK(K).  Thus, the value of
-** aReadMark[K] cannot changed while there is a reader is using that mark
-** since the reader will be holding a shared lock on WAL_READ_LOCK(K).
-**
-** The checkpointer may only transfer frames from WAL to database where
-** the frame numbers are less than or equal to every aReadMark[] that is
-** in use (that is, every aReadMark[j] for which there is a corresponding
-** WAL_READ_LOCK(j)).  New readers (usually) pick the aReadMark[] with the
-** largest value and will increase an unused aReadMark[] to mxFrame if there
-** is not already an aReadMark[] equal to mxFrame.  The exception to the
-** previous sentence is when nBackfill equals mxFrame (meaning that everything
-** in the WAL has been backfilled into the database) then new readers
-** will choose aReadMark[0] which has value 0 and hence such reader will
-** get all their all content directly from the database file and ignore 
-** the WAL.
-**
-** Writers normally append new frames to the end of the WAL.  However,
-** if nBackfill equals mxFrame (meaning that all WAL content has been
-** written back into the database) and if no readers are using the WAL
-** (in other words, if there are no WAL_READ_LOCK(i) where i>0) then
-** the writer will first "reset" the WAL back to the beginning and start
-** writing new content beginning at frame 1.
-**
-** We assume that 32-bit loads are atomic and so no locks are needed in
-** order to read from any aReadMark[] entries.

-**
-** The useWal parameter is true to force the use of the WAL and disable
-** the case where the WAL is bypassed because it has been completely
-** checkpointed.  If useWal==0 then this routine calls walIndexReadHdr() 
-** to make a copy of the wal-index header into pWal->hdr.  If the 
-** wal-index header has changed, *pChanged is set to 1 (as an indication 
-** to the caller that the local page cache is obsolete and needs to be 
-** flushed.)  When useWal==1, the wal-index header is assumed to already
-** be loaded and the pChanged parameter is unused.
-**
-** The caller must set the cnt parameter to the number of prior calls to
-** this routine during the current read attempt that returned WAL_RETRY.
-** This routine will start taking more aggressive measures to clear the
-** race conditions after multiple WAL_RETRY returns, and after an excessive
-** number of errors will ultimately return SQLITE_PROTOCOL.  The
-** SQLITE_PROTOCOL return indicates that some other process has gone rogue
-** and is not honoring the locking protocol.  There is a vanishingly small
-** chance that SQLITE_PROTOCOL could be returned because of a run of really
-** bad luck when there is lots of contention for the wal-index, but that
-** possibility is so small that it can be safely neglected, we believe.
-**
-** On success, this routine obtains a read lock on 
-** WAL_READ_LOCK(pWal->readLock).  The pWal->readLock integer is
-** in the range 0 <= pWal->readLock < WAL_NREADER.  If pWal->readLock==(-1)
-** that means the Wal does not hold any read lock.  The reader must not
-** access any database page that is modified by a WAL frame up to and
-** including frame number aReadMark[pWal->readLock].  The reader will
-** use WAL frames up to and including pWal->hdr.mxFrame if pWal->readLock>0
-** Or if pWal->readLock==0, then the reader will ignore the WAL
-** completely and get all content directly from the database file.
-** If the useWal parameter is 1 then the WAL will never be ignored and
-** this routine will always set pWal->readLock>0 on success.
-** When the read transaction is completed, the caller must release the
-** lock on WAL_READ_LOCK(pWal->readLock) and set pWal->readLock to -1.
-**
-** This routine uses the nBackfill and aReadMark[] fields of the header
-** to select a particular WAL_READ_LOCK() that strives to let the
-** checkpoint process do as much work as possible.  This routine might
-** update values of the aReadMark[] array in the header, but if it does
-** so it takes care to hold an exclusive lock on the corresponding

-** Adjust the WhereLoop.nOut value downward to account for terms of the
-** WHERE clause that reference the loop but which are not used by an
-** index.
-*
-** For every WHERE clause term that is not used by the index
-** and which has a truth probability assigned by one of the likelihood(),
-** likely(), or unlikely() SQL functions, reduce the estimated number
-** of output rows by the probability specified.
-**
-** TUNING:  For every WHERE clause term that is not used by the index
-** and which does not have an assigned truth probability, heuristics
-** described below are used to try to estimate the truth probability.
-** TODO --> Perhaps this is something that could be improved by better
-** table statistics.
-**
-** Heuristic 1:  Estimate the truth probability as 93.75%.  The 93.75%
-** value corresponds to -1 in LogEst notation, so this means decrement
-** the WhereLoop.nOut field for every such WHERE clause term.
-**
-** Heuristic 2:  If there exists one or more WHERE clause terms of the
-** form "x==EXPR" and EXPR is not a constant 0 or 1, then make sure the
-** final output row estimate is no greater than 1/4 of the total number
-** of rows in the table.  In other words, assume that x==EXPR will filter
-** out at least 3 out of 4 rows.  If EXPR is -1 or 0 or 1, then maybe the
-** "x" column is boolean or else -1 or 0 or 1 is a common default value
-** on the "x" column and so in that case only cap the output row estimate
-** at 1/2 instead of 1/4.

-** Add all WhereLoop objects for a single table of the join where the table

-**
-** The costs (WhereLoop.rRun) of the b-tree loops added by this function
-** are calculated as follows:
-**
-** For a full scan, assuming the table (or index) contains nRow rows:
-**
-**     cost = nRow * 3.0                    // full-table scan
-**     cost = nRow * K                      // scan of covering index
-**     cost = nRow * (K+3.0)                // scan of non-covering index
-**
-** where K is a value between 1.1 and 3.0 set based on the relative 
-** estimated average size of the index and table records.
-**
-** For an index scan, where nVisit is the number of index rows visited
-** by the scan, and nSeek is the number of seek operations required on 
-** the index b-tree:
-**
-**     cost = nSeek * (log(nRow) + K * nVisit)          // covering index
-**     cost = nSeek * (log(nRow) + (K+3.0) * nVisit)    // non-covering index
-**
-** Normally, nSeek is 1. nSeek values greater than 1 come about if the 
-** WHERE clause includes "x IN (....)" terms used in place of "x=?". Or when 
-** implicit "x IN (SELECT x FROM tbl)" terms are added for skip-scans.
-**
-** The estimated values (nRow, nVisit, nSeek) often contain a large amount
-** of uncertainty.  For this reason, scoring is designed to pick plans that
-** "do the least harm" if the estimates are inaccurate.  For example, a
-** log(nRow) factor is omitted from a non-covering index scan in order to
-** bias the scoring in favor of using an index, since the worst-case
-** performance of using an index is far better than the worst-case performance
-** of a full table scan.

-** Generate the beginning of the loop used for WHERE clause processing.
-** The return value is a pointer to an opaque structure that contains
-** information needed to terminate the loop.  Later, the calling routine
-** should invoke sqlite3WhereEnd() with the return value of this function
-** in order to complete the WHERE clause processing.
-**
-** If an error occurs, this routine returns NULL.
-**
-** The basic idea is to do a nested loop, one loop for each table in
-** the FROM clause of a select.  (INSERT and UPDATE statements are the
-** same as a SELECT with only a single table in the FROM clause.)  For
-** example, if the SQL is this:
-**
-**       SELECT * FROM t1, t2, t3 WHERE ...;
-**
-** Then the code generated is conceptually like the following:
-**
-**      foreach row1 in t1 do       \    Code generated
-**        foreach row2 in t2 do      |-- by sqlite3WhereBegin()
-**          foreach row3 in t3 do   /
-**            ...
-**          end                     \    Code generated
-**        end                        |-- by sqlite3WhereEnd()
-**      end                         /
-**
-** Note that the loops might not be nested in the order in which they
-** appear in the FROM clause if a different order is better able to make
-** use of indices.  Note also that when the IN operator appears in
-** the WHERE clause, it might result in additional nested loops for
-** scanning through all values on the right-hand side of the IN.
-**
-** There are Btree cursors associated with each table.  t1 uses cursor
-** number pTabList->a[0].iCursor.  t2 uses the cursor pTabList->a[1].iCursor.
-** And so forth.  This routine generates code to open those VDBE cursors
-** and sqlite3WhereEnd() generates the code to close them.
-**
-** The code that sqlite3WhereBegin() generates leaves the cursors named
-** in pTabList pointing at their appropriate entries.  The [...] code
-** can use OP_Column and OP_Rowid opcodes on these cursors to extract
-** data from the various tables of the loop.
-**
-** If the WHERE clause is empty, the foreach loops must each scan their
-** entire tables.  Thus a three-way join is an O(N^3) operation.  But if
-** the tables have indices and there are terms in the WHERE clause that
-** refer to those indices, a complete table scan can be avoided and the
-** code will run much faster.  Most of the work of this routine is checking
-** to see if there are indices that can be used to speed up the loop.
-**
-** Terms of the WHERE clause are also used to limit which rows actually
-** make it to the "..." in the middle of the loop.  After each "foreach",
-** terms of the WHERE clause that use only terms in that loop and outer
-** loops are evaluated and if false a jump is made around all subsequent
-** inner loops (or around the "..." if the test occurs within the inner-
-** most loop)
-**
-** OUTER JOINS
-**
-** An outer join of tables t1 and t2 is conceptally coded as follows:
-**
-**    foreach row1 in t1 do
-**      flag = 0
-**      foreach row2 in t2 do
-**        start:
-**          ...
-**          flag = 1
-**      end
-**      if flag==0 then
-**        move the row2 cursor to a null row
-**        goto start
-**      fi
-**    end
-**
-** ORDER BY CLAUSE PROCESSING
-**
-** pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause
-** if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement
-** if there is one.  If there is no ORDER BY clause or if this routine
-** is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
-**
-** The iIdxCur parameter is the cursor number of an index.  If 
-** WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index
-** to use for OR clause processing.  The WHERE clause should use this
-** specific cursor.  If WHERE_ONEPASS_DESIRED is set, then iIdxCur is
-** the first cursor in an array of cursors for all indices.  iIdxCur should
-** be used to compute the appropriate cursor depending on which index is
-** used.

-** The query generator uses an array of instances of this structure to
-** help it analyze the subexpressions of the WHERE clause.  Each WHERE
-** clause subexpression is separated from the others by AND operators,
-** usually, or sometimes subexpressions separated by OR.
-**
-** All WhereTerms are collected into a single WhereClause structure.  
-** The following identity holds:
-**
-**        WhereTerm.pWC->a[WhereTerm.idx] == WhereTerm
-**
-** When a term is of the form:
-**
-**              X <op> <expr>
-**
-** where X is a column name and <op> is one of certain operators,
-** then WhereTerm.leftCursor and WhereTerm.u.leftColumn record the
-** cursor number and column number for X.  WhereTerm.eOperator records
-** the <op> using a bitmask encoding defined by WO_xxx below.  The
-** use of a bitmask encoding for the operator allows us to search
-** quickly for terms that match any of several different operators.
-**
-** A WhereTerm might also be two or more subterms connected by OR:
-**
-**         (t1.X <op> <expr>) OR (t1.Y <op> <expr>) OR ....
-**
-** In this second case, wtFlag has the TERM_ORINFO bit set and eOperator==WO_OR
-** and the WhereTerm.u.pOrInfo field points to auxiliary information that
-** is collected about the OR clause.
-**
-** If a term in the WHERE clause does not match either of the two previous
-** categories, then eOperator==0.  The WhereTerm.pExpr field is still set
-** to the original subexpression content and wtFlags is set up appropriately
-** but no other fields in the WhereTerm object are meaningful.
-**
-** When eOperator!=0, prereqRight and prereqAll record sets of cursor numbers,
-** but they do so indirectly.  A single WhereMaskSet structure translates
-** cursor number into bits and the translated bit is stored in the prereq
-** fields.  The translation is used in order to maximize the number of
-** bits that will fit in a Bitmask.  The VDBE cursor numbers might be
-** spread out over the non-negative integers.  For example, the cursor
-** numbers might be 3, 8, 9, 10, 20, 23, 41, and 45.  The WhereMaskSet
-** translates these sparse cursor numbers into consecutive integers
-** beginning with 0 in order to make the best possible use of the available
-** bits in the Bitmask.  So, in the example above, the cursor numbers
-** would be mapped into integers 0 through 7.
-**
-** The number of terms in a join is limited by the number of bits
-** in prereqRight and prereqAll.  The default is 64 bits, hence SQLite
-** is only able to process joins with 64 or fewer tables.

-** Disable a term in the WHERE clause.  Except, do not disable the term
-** if it controls a LEFT OUTER JOIN and it did not originate in the ON
-** or USING clause of that join.
-**
-** Consider the term t2.z='ok' in the following queries:
-**
-**   (1)  SELECT * FROM t1 LEFT JOIN t2 ON t1.a=t2.x WHERE t2.z='ok'
-**   (2)  SELECT * FROM t1 LEFT JOIN t2 ON t1.a=t2.x AND t2.z='ok'
-**   (3)  SELECT * FROM t1, t2 WHERE t1.a=t2.x AND t2.z='ok'
-**
-** The t2.z='ok' is disabled in the in (2) because it originates
-** in the ON clause.  The term is disabled in (3) because it is not part
-** of a LEFT OUTER JOIN.  In (1), the term is not disabled.
-**
-** Disabling a term causes that term to not be tested in the inner loop
-** of the join.  Disabling is an optimization.  When terms are satisfied
-** by indices, we disable them to prevent redundant tests in the inner
-** loop.  We would get the correct results if nothing were ever disabled,
-** but joins might run a little slower.  The trick is to disable as much
-** as we can without disabling too much.  If we disabled in (1), we'd get
-** the wrong answer.  See ticket #813.
-**
-** If all the children of a term are disabled, then that term is also
-** automatically disabled.  In this way, terms get disabled if derived

-** Only the parent term was in the original WHERE clause.  The child1
-** and child2 terms were added by the LIKE optimization.  If both of
-** the virtual child terms are valid, then testing of the parent can be 
-** skipped.
-**
-** Usually the parent term is marked as TERM_CODED.  But if the parent
-** term was originally TERM_LIKE, then the parent gets TERM_LIKECOND instead.
-** The TERM_LIKECOND marking indicates that the term should be coded inside

-** in consecutive registers and the index of the first register is returned.
-**
-** In the example above nEq==2.  But this subroutine works for any value
-** of nEq including 0.  If nEq==0, this routine is nearly a no-op.
-** The only thing it does is allocate the pLevel->iMem memory cell and

-**
-** The nExtraReg parameter is 0 or 1.  It is 0 if all WHERE clause constraints
-** are == or IN and are covered by the nEq.  nExtraReg is 1 if there is
-** an inequality constraint (such as the "c>=5 AND c<10" in the example) that
-** occurs after the nEq quality constraints.
-**
-** This routine allocates a range of nEq+nExtraReg memory cells and returns

-** Analyze a term that consists of two or more OR-connected
-** subterms.  So in:
-**
-**     ... WHERE  (a=5) AND (b=7 OR c=9 OR d=13) AND (d=13)
-**                          ^^^^^^^^^^^^^^^^^^^^
-**
-** This routine analyzes terms such as the middle term in the above example.
-** A WhereOrTerm object is computed and attached to the term under
-** analysis, regardless of the outcome of the analysis.  Hence:
-**
-**     WhereTerm.wtFlags   |=  TERM_ORINFO
-**     WhereTerm.u.pOrInfo  =  a dynamically allocated WhereOrTerm object
-**
-** The term being analyzed must have two or more of OR-connected subterms.
-** A single subterm might be a set of AND-connected sub-subterms.
-** Examples of terms under analysis:
-**
-**     (A)     t1.x=t2.y OR t1.x=t2.z OR t1.y=15 OR t1.z=t3.a+5
-**     (B)     x=expr1 OR expr2=x OR x=expr3
-**     (C)     t1.x=t2.y OR (t1.x=t2.z AND t1.y=15)
-**     (D)     x=expr1 OR (y>11 AND y<22 AND z LIKE '*hello*')
-**     (E)     (p.a=1 AND q.b=2 AND r.c=3) OR (p.x=4 AND q.y=5 AND r.z=6)
-**     (F)     x>A OR (x=A AND y>=B)
-**
-** CASE 1:
-**
-** If all subterms are of the form T.C=expr for some single column of C and
-** a single table T (as shown in example B above) then create a new virtual
-** term that is an equivalent IN expression.  In other words, if the term
-** being analyzed is:
-**
-**      x = expr1  OR  expr2 = x  OR  x = expr3
-**
-** then create a new virtual term like this:
-**
-**      x IN (expr1,expr2,expr3)
-**
-** CASE 2:
-**
-** If there are exactly two disjuncts and one side has x>A and the other side
-** has x=A (for the same x and A) then add a new virtual conjunct term to the
-** WHERE clause of the form "x>=A".  Example:
-**
-**      x>A OR (x=A AND y>B)    adds:    x>=A
-**
-** The added conjunct can sometimes be helpful in query planning.
-**
-** CASE 3:
-**
-** If all subterms are indexable by a single table T, then set
-**
-**     WhereTerm.eOperator              =  WO_OR
-**     WhereTerm.u.pOrInfo->indexable  |=  the cursor number for table T
-**
-** A subterm is "indexable" if it is of the form
-** "T.C <op> <expr>" where C is any column of table T and 
-** <op> is one of "=", "<", "<=", ">", ">=", "IS NULL", or "IN".
-** A subterm is also indexable if it is an AND of two or more
-** subsubterms at least one of which is indexable.  Indexable AND 
-** subterms have their eOperator set to WO_AND and they have
-** u.pAndInfo set to a dynamically allocated WhereAndTerm object.
-**
-** From another point of view, "indexable" means that the subterm could
-** potentially be used with an index if an appropriate index exists.
-** This analysis does not consider whether or not the index exists; that
-** is decided elsewhere.  This analysis only looks at whether subterms
-** appropriate for indexing exist.
-**
-** All examples A through E above satisfy case 3.  But if a term
-** also satisfies case 1 (such as B) we know that the optimizer will
-** always prefer case 1, so in that case we pretend that case 3 is not
-** satisfied.
-**
-** It might be the case that multiple tables are indexable.  For example,
-** (E) above is indexable on tables P, Q, and R.
-**
-** Terms that satisfy case 3 are candidates for lookup by using
-** separate indices to find rowids for each subterm and composing
-** the union of all rowids using a RowSet object.  This is similar
-** to "bitmap indices" in other database engines.
-**
-** OTHERWISE:
-**
-** If none of cases 1, 2, or 3 apply, then leave the eOperator set to
-** zero.  This term is not useful for search.

-:: Multi-Platform Build Tool for MSVC
-::
-
-REM
-REM This batch script is used to build the SQLite DLL for multiple platforms
-REM and configurations using MSVC.  The built SQLite DLLs, their associated
-REM import libraries, and optionally their symbols files, are placed within
-REM the directory specified on the command line, in sub-directories named for
-REM their respective platforms and configurations.  This batch script must be
-REM run from inside a Visual Studio Command Prompt for the desired version of
-REM Visual Studio ^(the initial platform configured for the command prompt does
-REM not really matter^).  Exactly one command line argument is required, the
-REM name of an existing directory to be used as the final destination directory
-REM for the generated output files, which will be placed in sub-directories
-REM created therein.  Ideally, the directory specified should be empty.
-REM
-REM Example:
-REM
-REM                        CD /D C:\dev\sqlite\core
-REM                        CALL tool\build-all-msvc.bat C:\Temp
-REM
-REM In the example above, "C:\dev\sqlite\core" represents the root of the
-REM source tree for SQLite and "C:\Temp" represents the final destination
-REM directory for the generated output files.
-REM
-REM Please note that the SQLite build process performed by the Makefile
-REM associated with this batch script requires a Tcl shell to be present
-REM in a directory contained in the PATH environment variable unless a
-REM pre-existing amalgamation file is used.
-REM
-REM There are several environment variables that may be set to modify the
-REM behavior of this batch script and its associated Makefile.  The list of
-REM platforms to build may be overriden by using the PLATFORMS environment
-REM variable, which should contain a list of platforms ^(e.g. x86 x86_amd64
-REM x86_arm^).  All platforms must be supported by the version of Visual Studio
-REM being used.  The list of configurations to build may be overridden by
-REM setting the CONFIGURATIONS environment variable, which should contain a
-REM list of configurations to build ^(e.g. Debug Retail^).  Neither of these
-REM variable values may contain any double quotes, surrounding or embedded.
-REM
-REM Finally, the NCRTLIBPATH, NUCRTLIBPATH, and NSDKLIBPATH environment
-REM variables may be set to specify the location of the CRT, Universal CRT, and
-REM Windows SDK, respectively, that may be needed to compile executables native
-REM to the architecture of the build machine during any cross-compilation that
-REM may be necessary, depending on the platforms to be built.  These values in
-REM these three variables should be surrounded by double quotes if they contain
-REM spaces.
-REM
-REM There are a few other environment variables that impact the build process
-REM when set ^(to anything^), they are:
-REM
-REM                        USE_AUTOCONF_MAKEFILE
-REM
-REM When set, the "autoconf" Makefile for MSVC will be used instead of the main
-REM Makefile for MSVC.  It must exist at "%ROOT%\autoconf\Makefile.msc".
-REM
-REM                        NOCLEAN
-REM
-REM When set, the "clean" target will not be used during each build iteration.
-REM However, the target binaries, if any, will still be deleted manually prior
-REM to being rebuilt.  Setting this environment variable is only rarely needed
-REM and could cause issues in some circumstances; therefore, setting it is not
-REM recommended.
-REM
-REM                        NOSYMBOLS
-REM
-REM When set, copying of symbol files ^(*.pdb^) created during the build will
-REM be skipped and they will not appear in the final destination directory.
-REM Setting this environment variable is never strictly needed and could cause
-REM issues in some circumstances; therefore, setting it is not recommended.
-REM
-REM                        NOMEMDEBUG
-REM
-REM When set, disables use of MEMDEBUG when building binaries for the "Debug"
-REM configuration.
-REM
-REM                        BUILD_ALL_SHELL
-REM
-REM When set, the command line shell will be built for each selected platform
-REM and configuration as well.  In addition, the command line shell binaries
-REM will be copied, with their symbols, to the final destination directory.
-REM
-REM                        USE_WINV63_NSDKLIBPATH
-REM
-REM When set, modifies how the NSDKLIBPATH environment variable is built, based
-REM on the WindowsSdkDir environment variable.  It forces this batch script to
-REM assume the Windows 8.1 SDK location should be used.
-REM
-REM                        USE_WINV100_NSDKLIBPATH
-REM
-REM When set, modifies how the NSDKLIBPATH environment variable is built, based
-REM on the WindowsSdkDir environment variable.  It causes this batch script to
-REM assume the Windows 10.0 SDK location should be used.
-REM
-REM                        NMAKE_ARGS
-REM                        NMAKE_ARGS_DEBUG
-REM                        NMAKE_ARGS_RETAIL
-REM
-REM When set, these values are expanded and passed to the NMAKE command line,
-REM after its other arguments.  These may be used to specify additional NMAKE
-REM options, for example:
-REM
-REM                        SET NMAKE_ARGS=FOR_WINRT=1
-REM                        SET NMAKE_ARGS_DEBUG=MEMDEBUG=1
-REM                        SET NMAKE_ARGS_RETAIL=WIN32HEAP=1
-REM
-REM Using the above command before running this tool will cause the compiled
-REM binaries to target the WinRT environment, which provides a subset of the
-REM Win32 API.
-REM
-REM                        DLL_FILE_NAME
-REM                        DLL_PDB_FILE_NAME
-REM                        LIB_FILE_NAME
-REM                        EXE_FILE_NAME
-REM                        EXE_PDB_FILE_NAME
-REM
-REM When set, these values will override the associated target file name used
-REM for the build.

-*************************************************************************
-**
-** This program implements a high-speed version of the VACUUM command.
-** It repacks an SQLite database to remove as much unused space as
-** possible and to relocate content sequentially in the file.
-**
-** This program runs faster and uses less temporary disk space than the
-** built-in VACUUM command.  On the other hand, this program has a number
-** of important restrictions relative to the built-in VACUUM command.
-**
-**  (1)  The caller must ensure that no other processes are accessing the
-**       database file while the vacuum is taking place.  The usual SQLite
-**       file locking is insufficient for this.  The caller must use
-**       external means to make sure only this one routine is reading and
-**       writing the database.
-**
-**  (2)  Database reconfiguration such as page size or auto_vacuum changes
-**       are not supported by this utility.
-**
-**  (3)  The database file might be renamed if a power loss or crash
-**       occurs at just the wrong moment.  Recovery must be prepared to
-**       to deal with the possibly changed filename.
-**
-** This program is intended as a *Demonstration Only*.  The intent of this
-** program is to provide example code that application developers can use
-** when creating similar functionality in their applications.
-**
-** To compile this program:
-**
-**     cc fast_vacuum.c sqlite3.c
-**
-** Add whatever linker options are required.  (Example: "-ldl -lpthread").
-** Then to run the program:
-**
-**    ./a.out file-to-vacuum

-*************************************************************************
-**
-** This is a utility program designed to aid running the SQLite library
-** against an external fuzzer, such as American Fuzzy Lop (AFL)
-** (http://lcamtuf.coredump.cx/afl/).  Basically, this program reads
-** SQL text from standard input and passes it through to SQLite for evaluation,
-** just like the "sqlite3" command-line shell.  Differences from the
-** command-line shell:
-**
-**    (1)  The complex "dot-command" extensions are omitted.  This
-**         prevents the fuzzer from discovering that it can run things
-**         like ".shell rm -rf ~"
-**
-**    (2)  The database is opened with the SQLITE_OPEN_MEMORY flag so that
-**         no disk I/O from the database is permitted.  The ATTACH command
-**         with a filename still uses an in-memory database.
-**
-**    (3)  The main in-memory database can be initialized from a template
-**         disk database so that the fuzzer starts with a database containing
-**         content.
-**
-**    (4)  The eval() SQL function is added, allowing the fuzzer to do 
-**         interesting recursive operations.
-**
-**    (5)  An error is raised if there is a memory leak.
-**
-** The input text can be divided into separate test cases using comments
-** of the form:
-**
-**       |****<...>****|
-**
-** where the "..." is arbitrary text. (Except the "|" should really be "/".
-** "|" is used here to avoid compiler errors about nested comments.)
-** A separate in-memory SQLite database is created to run each test case.
-** This feature allows the "queue" of AFL to be captured into a single big
-** file using a command like this:
-**
-**    (for i in id:*; do echo '|****<'$i'>****|'; cat $i; done) >~/all-queue.txt
-**
-** (Once again, change the "|" to "/") Then all elements of the AFL queue
-** can be run in a single go (for regression testing, for example) by typing:
-**
-**    fuzzershell -f ~/all-queue.txt
-**
-** After running each chunk of SQL, the database connection is closed.  The
-** program aborts if the close fails or if there is any unfreed memory after
-** the close.
-**
-** New test cases can be appended to all-queue.txt at any time.  If redundant
-** test cases are added, they can be eliminated by running:
-**
-**    fuzzershell -f ~/all-queue.txt --unique-cases ~/unique-cases.txt

-OVERVIEW
-
-  The SQLite library is capable of parsing SQL foreign key constraints 
-  supplied as part of CREATE TABLE statements, but it does not actually 
-  implement them. However, most of the features of foreign keys may be
-  implemented using SQL triggers, which SQLite does support. This text
-  file describes a feature of the SQLite shell tool (sqlite3) that
-  extracts foreign key definitions from an existing SQLite database and
-  creates the set of CREATE TRIGGER statements required to implement
-  the foreign key constraints.
-
-CAPABILITIES
-
-  An SQL foreign key is a constraint that requires that each row in
-  the "child" table corresponds to a row in the "parent" table. For
-  example, the following schema:
-
-    CREATE TABLE parent(a, b, c, PRIMARY KEY(a, b));
-    CREATE TABLE child(d, e, f, FOREIGN KEY(d, e) REFERENCES parent(a, b));
-
-  implies that for each row in table "child", there must be a row in
-  "parent" for which the expression (child.d==parent.a AND child.e==parent.b) 
-  is true. The columns in the parent table are required to be either the
-  primary key columns or subject to a UNIQUE constraint. There is no such
-  requirement for the columns of the child table.
-
-  At this time, all foreign keys are implemented as if they were 
-  "MATCH NONE", even if the declaration specified "MATCH PARTIAL" or 
-  "MATCH FULL". "MATCH NONE" means that if any of the key columns in
-  the child table are NULL, then there is no requirement for a corresponding
-  row in the parent table. So, taking this into account, the expression that
-  must be true for every row of the child table in the above example is
-  actually:
-
-      (child.d IS NULL) OR 
-      (child.e IS NULL) OR 
-      (child.d==parent.a AND child.e==parent.b)
-
-  Attempting to insert or update a row in the child table so that the 
-  affected row violates this constraint results in an exception being 
-  thrown.
-
-  The effect of attempting to delete or update a row in the parent table 
-  so that the constraint becomes untrue for one or more rows in the child
-  table depends on the "ON DELETE" or "ON UPDATE" actions specified as
-  part of the foreign key definition, respectively. Three different actions
-  are supported: "RESTRICT" (the default), "CASCADE" and "SET NULL". SQLite
-  will also parse the "SET DEFAULT" action, but this is not implemented
-  and "RESTRICT" is used instead.
-
-    RESTRICT: Attempting to update or delete a row in the parent table so
-              that the constraint becomes untrue for one or more rows in
-              the child table is not allowed. An exception is thrown.
-
-    CASCADE:  Instead of throwing an exception, all corresponding child table
-              rows are either deleted (if the parent row is being deleted)
-              or updated to match the new parent key values (if the parent 
-              row is being updated).
-
-    SET NULL: Instead of throwing an exception, the foreign key fields of
-              all corresponding child table rows are set to NULL.
-
-LIMITATIONS
-
-  Apart from those limitiations described above:
-
-    * Implicit mapping to composite primary keys is not supported. If
-      a parent table has a composite primary key, then any child table
-      that refers to it must explicitly map each column. For example, given
-      the following definition of table "parent":
-
-        CREATE TABLE parent(a, b, c, PRIMARY KEY(a, b));
-
-      only the first of the following two definitions of table "child"
-      is supported:
-
-        CREATE TABLE child(d, e, f, FOREIGN KEY(d, e) REFERENCES parent(a, b));
-        CREATE TABLE child(d, e, f, FOREIGN KEY(d, e) REFERENCES parent);
-
-      An implicit reference to a composite primary key is detected as an
-      error when the program is run (see below).
-
-    * SQLite does not support recursive triggers, and therefore this program
-      does not support recursive CASCADE or SET NULL foreign key 
-      relationships. If the parent and the child tables of a CASCADE or
-      SET NULL foreign key are the same table, the generated triggers will
-      malfunction. This is also true if the recursive foreign key constraint
-      is indirect (for example if table A references table B which references
-      table A with a CASCADE or SET NULL foreign key constraint).
-
-      Recursive CASCADE or SET NULL foreign key relationships are *not*
-      detected as errors when the program is run. Buyer beware.
-
-USAGE
-
-  The functionality is accessed through an sqlite3 shell tool "dot-command":
-
-    .genfkey ?--no-drop? ?--ignore-errors? ?--exec?
-
-  When this command is run, it first checks the schema of the open SQLite
-  database for foreign key related errors or inconsistencies. For example,
-  a foreign key that refers to a parent table that does not exist, or
-  a foreign key that refers to columns in a parent table that are not
-  guaranteed to be unique. If such errors are found and the --ignore-errors
-  option was not present, a message for each one is printed to stderr and
-  no further processing takes place.
-
-  If errors are found and the --ignore-errors option is passed, then
-  no error messages are printed. No "CREATE TRIGGER" statements are generated
-  for foriegn-key definitions that contained errors, they are silently
-  ignored by subsequent processing.
-
-  All triggers generated by this command have names that match the pattern
-  "genfkey*". Unless the --no-drop option is specified, then the program
-  also generates a "DROP TRIGGER" statement for each trigger that exists
-  in the database with a name that matches this pattern. This allows the
-  program to be used to upgrade a database schema for which foreign key
-  triggers have already been installed (i.e. after new tables are created
-  or existing tables dropped).
-
-  Finally, a series of SQL trigger definitions (CREATE TRIGGER statements) 
-  that implement the foreign key constraints found in the database schema are
-  generated.
-
-  If the --exec option was passed, then all generated SQL is immediately
-  executed on the database. Otherwise, the generated SQL strings are output
-  in the same way as the results of SELECT queries are. Normally, this means
-  they will be printed to stdout, but this can be configured using other
-  dot-commands (i.e. ".output").
-
-  The simplest way to activate the foriegn key definitions in a database
-  is simply to open it using the shell tool and enter the command 
-  ".genfkey --exec":
-
-    sqlite> .genfkey --exec

-*************************************************************************
-** Driver template for the LEMON parser generator.
-**
-** The "lemon" program processes an LALR(1) input grammar file, then uses
-** this template to construct a parser.  The "lemon" program inserts text
-** at each "%%" line.  Also, any "P-a-r-s-e" identifer prefix (without the
-** interstitial "-" characters) contained in this template is changed into
-** the value of the %name directive from the grammar.  Otherwise, the content
-** of this template is copied straight through into the generate parser
-** source file.
-**
-** The following is the concatenation of all %include directives from the
-** input grammar file:
-*/
-#include <stdio.h>
-/************ Begin %include sections from the grammar ************************/
-%%
-/**************** End of %include directives **********************************/
-/* These constants specify the various numeric values for terminal symbols
-** in a format understandable to "makeheaders".  This section is blank unless
-** "lemon" is run with the "-m" command-line option.
-***************** Begin makeheaders token definitions *************************/
-%%
-/**************** End makeheaders token definitions ***************************/
-
-/* The next sections is a series of control #defines.
-** various aspects of the generated parser.
-**    YYCODETYPE         is the data type used to store the integer codes
-**                       that represent terminal and non-terminal symbols.
-**                       "unsigned char" is used if there are fewer than
-**                       256 symbols.  Larger types otherwise.
-**    YYNOCODE           is a number of type YYCODETYPE that is not used for
-**                       any terminal or nonterminal symbol.
-**    YYFALLBACK         If defined, this indicates that one or more tokens
-**                       (also known as: "terminal symbols") have fall-back
-**                       values which should be used if the original symbol
-**                       would not parse.  This permits keywords to sometimes
-**                       be used as identifiers, for example.
-**    YYACTIONTYPE       is the data type used for "action codes" - numbers
-**                       that indicate what to do in response to the next
-**                       token.
-**    ParseTOKENTYPE     is the data type used for minor type for terminal
-**                       symbols.  Background: A "minor type" is a semantic
-**                       value associated with a terminal or non-terminal
-**                       symbols.  For example, for an "ID" terminal symbol,
-**                       the minor type might be the name of the identifier.
-**                       Each non-terminal can have a different minor type.
-**                       Terminal symbols all have the same minor type, though.
-**                       This macros defines the minor type for terminal 
-**                       symbols.
-**    YYMINORTYPE        is the data type used for all minor types.
-**                       This is typically a union of many types, one of
-**                       which is ParseTOKENTYPE.  The entry in the union
-**                       for terminal symbols is called "yy0".
-**    YYSTACKDEPTH       is the maximum depth of the parser's stack.  If
-**                       zero the stack is dynamically sized using realloc()
-**    ParseARG_SDECL     A static variable declaration for the %extra_argument
-**    ParseARG_PDECL     A parameter declaration for the %extra_argument
-**    ParseARG_PARAM     Code to pass %extra_argument as a subroutine parameter
-**    ParseARG_STORE     Code to store %extra_argument into yypParser
-**    ParseARG_FETCH     Code to extract %extra_argument from yypParser
-**    ParseCTX_*         As ParseARG_ except for %extra_context
-**    YYERRORSYMBOL      is the code number of the error symbol.  If not
-**                       defined, then do no error processing.
-**    YYNSTATE           the combined number of states.
-**    YYNRULE            the number of rules in the grammar
-**    YYNTOKEN           Number of terminal symbols
-**    YY_MAX_SHIFT       Maximum value for shift actions
-**    YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
-**    YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
-**    YY_ERROR_ACTION    The yy_action[] code for syntax error
-**    YY_ACCEPT_ACTION   The yy_action[] code for accept
-**    YY_NO_ACTION       The yy_action[] code for no-op
-**    YY_MIN_REDUCE      Minimum value for reduce actions
-**    YY_MAX_REDUCE      Maximum value for reduce actions

-** action integer.  
-**
-** Suppose the action integer is N.  Then the action is determined as
-** follows
-**
-**   0 <= N <= YY_MAX_SHIFT             Shift N.  That is, push the lookahead

-**
-**   N between YY_MIN_REDUCE            Reduce by rule N-YY_MIN_REDUCE
-**     and YY_MAX_REDUCE
-**
-** The action table is constructed as a single large table named yy_action[].
-** Given state S and lookahead X, the action is computed as either:
-**
-**    (A)   N = yy_action[ yy_shift_ofst[S] + X ]
-**    (B)   N = yy_default[S]
-**
-** The (A) formula is preferred.  The B formula is used instead if
-** yy_lookahead[yy_shift_ofst[S]+X] is not equal to X.
-**
-** The formulas above are for computing the action when the lookahead is
-** a terminal symbol.  If the lookahead is a non-terminal (as occurs after
-** a reduce action) then the yy_reduce_ofst[] array is used in place of
-** the yy_shift_ofst[] array.
-**
-** The following are the tables generated in this section:
-**
-**  yy_action[]        A single table containing all actions.
-**  yy_lookahead[]     A table containing the lookahead for each entry in
-**                     yy_action.  Used to detect hash collisions.
-**  yy_shift_ofst[]    For each state, the offset into yy_action for
-**                     shifting terminals.
-**  yy_reduce_ofst[]   For each state, the offset into yy_action for
-**                     shifting non-terminals after a reduce.
-**  yy_default[]       Default action for each state.

-** and Z.  Whenever one of the tokens X, Y, or Z is input to the parser

-#
-# Use this script to build C-language source code for a program that uses
-# tclsqlite.c together with custom TCL scripts and/or C extensions for
-# either SQLite or TCL.
-#
-# Usage example:
-#
-#     tclsh mktclsqliteprog.tcl demoapp.c.in >demoapp.c
-#
-# The demoapp.c.in file contains a mixture of C code, TCL script, and
-# processing directives used by mktclsqliteprog.tcl to build the final C-code
-# output file.  Most lines of demoapp.c.in are copied straight through into
-# the output.  The following control directives are recognized:
-#
-# BEGIN_STRING
-#
-#      This marks the beginning of large string literal - usually a TCL
-#      script of some kind.  Subsequent lines of text through the first
-#      line that begins with END_STRING are converted into a C-language
-#      string literal.
-#
-# INCLUDE path
-#
-#      The path argument is the name of a file to be inserted in place of
-#      the INCLUDE line.  The path can begin with $ROOT to signify the
-#      root of the SQLite source tree, or $HOME to signify the directory
-#      that contains the demoapp.c.in input script itself.  If the path does
-#      not begin with either $ROOT or $HOME, then it is interpreted relative
-#      to the current working directory.
-#
-#      If the INCLUDE occurs in the middle of BEGIN_STRING...END_STRING
-#      then all of the text in the input file is converted into C-language
-#      string literals.
-#
-# None of the control directives described above will nest.  Only the
-# top-level input file ("demoapp.c.in" in the example) is interpreted.
-# referenced files are copied verbatim.

-#!/usr/bin/tclsh
-#
-# This script is used to generate a VSIX (Visual Studio Extension) file for
-# SQLite usable by Visual Studio.
-#
-# PREREQUISITES
-#
-# 1. Tcl 8.4 and later are supported, earlier versions have not been tested.
-#
-# 2. The "sqlite3.h" file is assumed to exist in the parent directory of the
-#    directory containing this script.  The [optional] second command line
-#    argument to this script may be used to specify an alternate location.
-#    This script also assumes that the "sqlite3.h" file corresponds with the
-#    version of the binaries to be packaged.  This assumption is not verified
-#    by this script.
-#
-# 3. The temporary directory specified in the TEMP or TMP environment variables
-#    must refer to an existing directory writable by the current user.
-#
-# 4. The "zip" and "unzip" command line tools must be located either in a
-#    directory contained in the PATH environment variable or specified as the
-#    exact file names to execute in the "ZipTool" and "UnZipTool" environment
-#    variables, respectively.
-#
-# 5. The template VSIX file (which is basically a zip file) must be located in
-#    a "win" directory inside the directory containing this script.  It should
-#    not contain any executable binaries.  It should only contain dynamic
-#    textual content files to be processed using [subst] and/or static content
-#    files to be copied verbatim.
-#
-# 6. The executable and other compiled binary files to be packaged into the
-#    final VSIX file (e.g. DLLs, LIBs, and PDBs) must be located in a single
-#    directory tree.  The top-level directory of the tree must be specified as
-#    the first command line argument to this script.  The second level
-#    sub-directory names must match those of the build configuration (e.g.
-#    "Debug" or "Retail").  The third level sub-directory names must match
-#    those of the platform (e.g. "x86", "x64", and "ARM").  For example, the
-#    binary files to be packaged would need to be organized as follows when
-#    packaging the "Debug" and "Retail" build configurations for the "x86" and
-#    "x64" platforms (in this example, "C:\temp" is the top-level directory as
-#    specified in the first command line argument):
-#
-#                         C:\Temp\Debug\x86\sqlite3.lib
-#                         C:\Temp\Debug\x86\sqlite3.dll
-#                         C:\Temp\Debug\x86\sqlite3.pdb
-#                         C:\Temp\Debug\x64\sqlite3.lib
-#                         C:\Temp\Debug\x64\sqlite3.dll
-#                         C:\Temp\Debug\x64\sqlite3.pdb
-#                         C:\Temp\Retail\x86\sqlite3.lib
-#                         C:\Temp\Retail\x86\sqlite3.dll
-#                         C:\Temp\Retail\x86\sqlite3.pdb
-#                         C:\Temp\Retail\x64\sqlite3.lib
-#                         C:\Temp\Retail\x64\sqlite3.dll
-#                         C:\Temp\Retail\x64\sqlite3.pdb
-#
-#    The above directory tree organization is performed automatically if the
-#    "tool\build-all-msvc.bat" batch script is used to build the binary files
-#    to be packaged.
-#
-# USAGE
-#
-# The first argument to this script is required and must be the name of the
-# top-level directory containing the directories and files organized into a
-# tree as described in item 6 of the PREREQUISITES section, above.  The second
-# argument is optional and if present must contain the name of the directory
-# containing the root of the source tree for SQLite.  The third argument is
-# optional and if present must contain the flavor the VSIX package to build.
-# Currently, the only supported package flavors are "WinRT", "WinRT81", "WP80",
-# "WP81", and "Win32".  The fourth argument is optional and if present must be
-# a string containing a list of platforms to include in the VSIX package.  The
-# platform list is "platform1,platform2,platform3".  The fifth argument is
-# optional and if present must contain the version of Visual Studio required by
-# the package.  Currently, the only supported versions are "2012" and "2013".
-# The package flavors "WinRT81" and "WP81" are only supported when the Visual
-# Studio version is "2013".  Typically, when on Windows, this script is
-# executed using commands similar to the following from a normal Windows
-# command prompt:
-#
-#                         CD /D C:\dev\sqlite\core
-#                         tclsh tool\mkvsix.tcl C:\Temp
-#
-# In the example above, "C:\dev\sqlite\core" represents the root of the source
-# tree for SQLite and "C:\Temp" represents the top-level directory containing
-# the executable and other compiled binary files, organized into a directory
-# tree as described in item 6 of the PREREQUISITES section, above.
-#
-# This script should work on non-Windows platforms as well, provided that all
-# the requirements listed in the PREREQUISITES section are met.
-#
-# NOTES
-#
-# The temporary directory is used as a staging area for the final VSIX file.
-# The template VSIX file is extracted, its contents processed, and then the
-# resulting files are packaged into the final VSIX file.

-# Documentation for this script. This may be output to stderr

-set ::USAGE_MESSAGE {
-This Tcl script is used to test the various compile time options 
-available for omitting code (the SQLITE_OMIT_xxx options). It
-should be invoked as follows:
-
-    <script> ?test-symbol? ?-makefile PATH-TO-MAKEFILE? ?-skip_run?
-
-The default value for ::MAKEFILE is "../Makefile.linux.gcc".
-
-If -skip_run option is given then only the compile part is attempted.
-
-This script builds the testfixture program and runs the SQLite test suite
-once with each SQLITE_OMIT_ option defined and then once with all options
-defined together. Each run is performed in a seperate directory created
-as a sub-directory of the current directory by the script. The output
-of the build is saved in <sub-directory>/build.log. The output of the
-test-suite is saved in <sub-directory>/test.log.
-
-Almost any SQLite makefile (except those generated by configure - see below)
-should work. The following properties are required:
-
-  * The makefile should support the "testfixture" target.
-  * The makefile should support the "test" target.
-  * The makefile should support the variable "OPTS" as a way to pass
-    options from the make command line to lemon and the C compiler.
-
-More precisely, the following two invocations must be supported:
-
-  $::MAKEBIN -f $::MAKEFILE testfixture OPTS="-DSQLITE_OMIT_ALTERTABLE=1"
-  $::MAKEBIN -f $::MAKEFILE test
-
-Makefiles generated by the sqlite configure program cannot be used as
-they do not respect the OPTS variable.

-

-
-    The number of tables in the database, including the SQLITE_MASTER table
-    used to store schema information.
-
-Number of indices
-
-    The total number of indices in the database.
-

-
-Size of the file in bytes
-
-    The total amount of disk space used by the entire database files.
-
-Bytes of user payload stored
-
-    The total number of bytes of user payload stored in the database. The
-    schema information in the SQLITE_MASTER table is not counted when
-    computing this number.  The percentage at the right shows the payload
-    divided by the total file size.
-
-Percentage of total database
-
-    The amount of the complete database file that is devoted to storing
-    information described by this category.
-
-Number of entries
-
-    The total number of B-Tree key/value pairs stored under this category.
-
-Bytes of storage consumed
-
-    The total amount of disk space required to store all B-Tree entries
-    under this category.  The is the total number of pages used times
-    the pages size.
-
-Bytes of payload
-
-    The amount of payload stored under this category.  Payload is the data
-    part of table entries and the key part of index entries.  The percentage
-    at the right is the bytes of payload divided by the bytes of storage 
-    consumed.
-
-Bytes of metadata
-
-    The amount of formatting and structural information stored in the
-    table or index.  Metadata includes the btree page header, the cell pointer
-    array, the size field for each cell, the left child pointer or non-leaf
-    cells, the overflow pointers for overflow cells, and the rowid value for
-    rowid table cells.  In other words, metadata is everything that is neither
-    unused space nor content.  The record header in the payload is counted as
-    content, not metadata.
-
-Average payload per entry
-
-    The average amount of payload on each entry.  This is just the bytes of
-    payload divided by the number of entries.
-
-Average unused bytes per entry
-
-    The average amount of free space remaining on all pages under this
-    category on a per-entry basis.  This is the number of unused bytes on
-    all pages divided by the number of entries.
-
-Non-sequential pages
-
-    The number of pages in the table or index that are out of sequence.
-    Many filesystems are optimized for sequential file access so a small
-    number of non-sequential pages might result in faster queries,
-    especially for larger database files that do not fit in the disk cache.
-    Note that after running VACUUM, the root page of each table or index is
-    at the beginning of the database file and all other pages are in a
-    separate part of the database file, resulting in a single non-
-    sequential page.
-
-Maximum payload per entry
-
-    The largest payload size of any entry.
-
-Entries that use overflow
-
-    The number of entries that user one or more overflow pages.
-
-Total pages used
-
-    This is the number of pages used to hold all information in the current
-    category.  This is the sum of index, primary, and overflow pages.
-
-Index pages used
-
-    This is the number of pages in a table B-tree that hold only key (rowid)
-    information and no data.
-
-Primary pages used
-
-    This is the number of B-tree pages that hold both key and data.
-
-Overflow pages used
-
-    The total number of overflow pages used for this category.
-
-Unused bytes on index pages
-
-    The total number of bytes of unused space on all index pages.  The
-    percentage at the right is the number of unused bytes divided by the
-    total number of bytes on index pages.
-
-Unused bytes on primary pages
-
-    The total number of bytes of unused space on all primary pages.  The
-    percentage at the right is the number of unused bytes divided by the
-    total number of bytes on primary pages.
-
-Unused bytes on overflow pages
-
-    The total number of bytes of unused space on all overflow pages.  The
-    percentage at the right is the number of unused bytes divided by the
-    total number of bytes on overflow pages.
-
-Unused bytes on all pages
-
-    The total number of bytes of unused space on all primary and overflow 
-    pages.  The percentage at the right is the number of unused bytes

-**
-**     gcc speedtest16.c sqlite3.o -ldl -I../src

-/*
-** Create a new delta.
-**
-** The delta is written into a preallocated buffer, zDelta, which
-** should be at least 60 bytes longer than the target file, zOut.
-** The delta string will be NUL-terminated, but it might also contain
-** embedded NUL characters if either the zSrc or zOut files are
-** binary.  This function returns the length of the delta string
-** in bytes, excluding the final NUL terminator character.
-**
-** Output Format:
-**
-** The delta begins with a base64 number followed by a newline.  This
-** number is the number of bytes in the TARGET file.  Thus, given a
-** delta file z, a program can compute the size of the output file
-** simply by reading the first line and decoding the base-64 number
-** found there.  The delta_output_size() routine does exactly this.
-**
-** After the initial size number, the delta consists of a series of
-** literal text segments and commands to copy from the SOURCE file.
-** A copy command looks like this:
-**
-**     NNN@MMM,
-**
-** where NNN is the number of bytes to be copied and MMM is the offset
-** into the source file of the first byte (both base-64).   If NNN is 0
-** it means copy the rest of the input file.  Literal text is like this:
-**
-**     NNN:TTTTT
-**
-** where NNN is the number of bytes of text (base-64) and TTTTT is the text.
-**
-** The last term is of the form
-**
-**     NNN;
-**
-** In this case, NNN is a 32-bit bigendian checksum of the output file
-** that can be used to verify that the delta applied correctly.  All
-** numbers are in base-64.
-**
-** Pure text files generate a pure text delta.  Binary files generate a
-** delta that may contain some binary data.
-**
-** Algorithm:
-**
-** The encoder first builds a hash table to help it find matching
-** patterns in the source file.  16-byte chunks of the source file
-** sampled at evenly spaced intervals are used to populate the hash
-** table.
-**
-** Next we begin scanning the target file using a sliding 16-byte
-** window.  The hash of the 16-byte window in the target is used to
-** search for a matching section in the source file.  When a match
-** is found, a copy command is added to the delta.  An effort is
-** made to extend the matching section to regions that come before
-** and after the 16-byte hash window.  A copy command is only issued
-** if the result would use less space that just quoting the text
-** literally. Literal text is added to the delta for sections that
-** do not match or which can not be encoded efficiently using copy
-** commands.

-# This script makes modifications to the vdbe.c source file which reduce
-# the amount of stack space required by the sqlite3VdbeExec() routine.
-#
-# The modifications performed by this script are optional.  The vdbe.c
-# source file will compile correctly with and without the modifications
-# performed by this script.  And all routines within vdbe.c will compute
-# the same result.  The modifications made by this script merely help
-# the C compiler to generate code for sqlite3VdbeExec() that uses less
-# stack space.
-#
-# Script usage:
-#
-#          mv vdbe.c vdbe.c.template
-#          tclsh vdbe-compress.tcl $CFLAGS <vdbe.c.template >vdbe.c
-#
-# Modifications made:
-#
-# All modifications are within the sqlite3VdbeExec() function.  The
-# modifications seek to reduce the amount of stack space allocated by
-# this routine by moving local variable declarations out of individual
-# opcode implementations and into a single large union.  The union contains
-# a separate structure for each opcode and that structure contains the
-# local variables used by that opcode.  In this way, the total amount
-# of stack space required by sqlite3VdbeExec() is reduced from the
-# sum of all local variables to the maximum of the local variable space
-# required for any single opcode.
-#
-# In order to be recognized by this script, local variables must appear
-# on the first line after the open curly-brace that begins a new opcode
-# implementation.  Local variables must not have initializers, though they
-# may be commented.
-#
-# The union definition is inserted in place of a special marker comment
-# in the preamble to the sqlite3VdbeExec() implementation.
