+# Developing Erlang/OTP
+
+The Erlang/OTP development repository is quite large and the make system
+contains a lot of functionality to help when a developing. This howto
+will try to showcase the most important features of the make system.
+
+The guide is mostly aimed towards development on a Unix platform, but
+most things should work also work using WSL on Windows. The guide also
+assumes that you are working in the git repositiory. Many of the
+scripts and tools described here are not available in the prebuilt tar
+archive that you can download for each release.
+
+*WARNING*: Only some of APIs mentioned in this guide are supported. This
+means that they may be removed or changed without prior notice, so do
+not depend on them in CI. For supported make targets see the
+[Install howto](INSTALL.md) and the [Testing howto](TESTING.md).
+
+The make system is not always as robust as one might like, so if for
+any reason something does not work, try doing a `git clean -Xfdq` and
+start from the beginning again. This normally only needs to be done when
+you jump in between different git branches, but it can a good thing to
+keep in mind whenever things do not work as you expect them to.
+
+*NOTE*: This instructions may vary for different versions of Erlang/OTP,
+so make sure to read the instructions for the version that you are working
+with.

+8. [Using Docker](#using-docker)
+    1. [Gidpod.io or VSCode dev container](#gitpod-io-or-vscode-dev-container)
+
+## Short version
+
+First make sure you have done all [preparations](#preparations) then
+do this:
+
+```bash
+git clone -b maint git@github.com:erlang/otp
+cd otp && export ERL_TOP=`pwd`
+./otp_build configure && make
+```
+
+When you have done changes, added tests or updated documentation, build and test like this:
+
+```bash
+cd lib/$APPLICATION_NAME
+make            # Rebuid application
+make test       # Run application tests
+make dialyzer   # Run dialyzer
+make docs       # Build the docs
+make xmllint    # Run xmllint on the docs
+```
+
+Then enable [Github Actions](#github-actions) and push the changes to your fork
+of Erlang/OTP to check that you have not missed anything.
+
+## Preparations
+
+Before you start working you need to clone the Erlang/OTP git repository
+and install any dependencies that you do not have. See
+[Required Utilities](INSTALL.md#required-utilities) and
+[Optional Utilities](INSTALL.md#optional-utilities) in [INSTALL.md](INSTALL.md)
+for a list of utilities to install. (Windows has its own [INSTALL Guide](INSTALL-WIN32.md)
+with its own [Required Utilities](INSTALL-WIN32.md#tools-you-need-and-their-environment)).
+
+Then you need to set `ERL_TOP` to point at the repository you are developing in.
+Not all make commands needs this environment variable set, but many do so it is
+good to get into the habit of always setting it.
+
+```bash
+cd /path/to/repository/otp
+export ERL_TOP=`pwd`
+```
+
+Make sure that you have read the [Contributing to Erlang/OTP](../CONTRIBUTING.md)
+guide if you intend to make a contribution to Erlang/OTP.
+
+### Faster builds
+
+Both `configure` and `make` take advantage of running in parallel if told to,
+so in order to speed up your development environment make sure to set:
+
+```bash
+## Change N to be at least the number of cores or hyper-threads available
+export MAKEFLAGS=-jN
+```
+
+The Erlang compiler can be run using a [Compile Server](https://www.erlang.org/doc/man/erlc.html#compile-server),
+this can cut from the total build time of Erlang/OTP by quite a lot,
+especially if you have a relatively slow machine.
+To enable set this environment variable:
+
+```bash
+export ERLC_USE_SERVER=true
+```
+
+Re-building all application in Erlang/OTP can take a while so it is possible
+to build only a subset of the applications. This is done by setting either
+`OTP_SMALL_BUILD` or `OTP_TINY_BUILD` to `true` when doing make at the top
+level. However, the simplest way is probably to just use the `./otp_build`
+wrapper that takes the options `-t` (tiny) or `-a` (all) and defaults to
+a small build.
+
+```bash
+# You need to have done ./configure before calling make or boot.
+OTP_TINY_BUILD=true make      ## Equivalent to ./otp_build boot -t
+OTP_SMALL_BUILD=true make     ## Equivalent to ./otp_build boot
+./otp_build boot -a           ## Equivalent to make
+```
+
+## Configuring
+
+You run configure by issuing the command:
+
+```bash
+./otp_build configure
+```
+
+On all operating systems except Windows you can also just run:
+
+```bash
+./configure
+```
+
+If you change any `Makefile`s you will need to re-run configure.
+If you update any `configure.ac` scripts you need to
+[update the configure scripts](INSTALL.md#updating-configure-scripts).
+
+### Help
+
+The toplevel configure will give help about the features that it provides.
+To get a full list of all features you need to use:
+
+```bash
+./configure --help=r
+```
+
+There is documentation for what most of the options mean in the
+[INSTALL.md](INSTALL.md#Configuring) howto.
+
+## Building and testing
+
+After you have done configure, you can do
+
+```bash
+make
+```
+
+on the top of this repository. That will compile all of Erlang/OTP.
+
+You can also build a specific application:
+
+```bash
+make stdlib
+make common_test
+```
+
+These make commands do not manage any dependencies, so if an application needs
+something from another you need to make sure that it is built. It is therefore
+good practice to first build all of Erlang/OTP and then build just the one that
+you are updating.
+
+You can also run tests from the top:
+
+```bash
+make test                # Run all tests, takes a **very** long time
+make stdlib_test         # Run only stdlib tests, takes less time
+                         # Run only lists_SUITE, takes even less time
+make stdlib_test ARGS="-suite lists_SUITE"
+                         # Run only member testcase in lists_SUITE
+make stdlib_test ARGS="-suite lists_SUITE -case member"
+```
+
+See [ct_run](https://www.erlang.org/doc/man/ct_run.html#) for a list of all options
+that you can pass to ARGS.
+
+You can run static analysis test:
+
+```bash
+make dialyzer            # Checks all of Erlang/OTP source code
+make xmllint             # Checks all documentation for xmllint errors
+```
+
+Most of the above targets also works for a "phony" target called `emulator` that
+represents erts and all its tools. So you can do this:
+
+```bash
+make emulator            # Build erts, epmd etc
+make emulator_test       # Run all emulator tests
+```
+
+If you want to pass a run-time flag to the emulator running the tests you can
+use the `ERL_ARGS` flags to `make test`. For example if you want to run tests
+using [off heap message queue data](https://www.erlang.org/doc/man/erlang.html#process_flag_message_queue_data)
+for all process you would do this:
+
+```bash
+ERL_ARGS="+hmqd off_heap" make emulator_test
+```
+
+### Build and test a specific application
+
+You can also build the application from within itself. Like this:
+
+```bash
+cd lib/stdlib && make
+```
+
+Each application has a bunch of make targets that you can use.
+
+```bash
+make                                # build all source for this application
+make test                           # run all tests for this application
+make test ARGS="-suite lists_SUITE" # run the lists_SUITE tests
+make dialyzer                       # run dialyzer for this application
+make docs                           # build all docs for this application
+make docs DOC_TARGETS="html"        # build html docs for this application
+make xmllint                        # run xmllint on the docs for this application
+```
+
+If you want to view what the documentation looks like for only your application
+you can do this:
+
+```bash
+(cd doc/src && make local_docs)
+```
+
+and then view `doc/html/index.html`.
+
+### Preloaded and Primary Bootstrap
+
+The Erlang code loader and compiler are written in Erlang, so in order to
+[bootstrap](https://en.wikipedia.org/wiki/Bootstrapping_(compilers))
+the system a number of compiled `.beam` files are commited into the
+Erlang/OTP git repository.
+
+The Erlang code located in [erts/preloaded/src](../erts/preloaded/src)
+is compiled into the VM and used to load enough code so that the code
+loader in the `kernel` application can be loaded. If you update any of
+that code you need to do a special preloaded update for the changes to
+take effect. This is done like this:
+
+```bash
+./otp_build update_preloaded [--no-commit]
+make  # Need to rebuild system after the preloaded has been updated
+```
+
+You need to have a working Erlang compiler in your path for this to work.
+In order to be able to compile the Erlang/OTP source code, there also needs
+to be a basic Erlang compiler committed into git. This is what is called the
+primary bootstrap. It is quite rare that you need to update this, but if you
+are extending the Erlang language and would like to use the new extensions
+in the Erlang/OTP source code you it needs to be updated. As an example, when
+we added `maps` to Erlang we first needed to have a commited primary bootstrap
+that could compile code with maps, before we actually could use maps anywhere.
+To update the primary bootstrap you do like this:
+
+```bash
+./otp_build update_primary [--no-commit]
+```
+
+*NOTE*: When submitting a PR to Erlang/OTP you will be asked to not include
+any commit updating preloaded or the primary bootstrap. This is because we
+cannot review the contents of binary files and thus cannot make sure they do
+not contain any malicious data.
+
+### Types and Flavors
+
+Erlang can be built using different types and flavors. Mostly the types and
+flavors change how the Erlang VM itself is built, but some also effect how
+application are built. Some of the types/flavors are:
+
+* Types
+  * opt (default)
+  * debug
+  * lcnt
+  * valgrind
+  * asan
+  * gcov
+* Flavor
+  * emu
+  * jit (default if available)
+
+To build using a type and or flavor you just pass it as a variable to make.
+For example:
+
+```bash
+make TYPE=debug
+make FLAVOR=emu
+make TYPE=lcnt FLAVOR=emu
+```
+
+As you can see it is possible to combine type and flavor to create many different
+versions of Erlang. You can then run these different versions by passing the
+`-emu_type` and/or `-emu_flavor` flags to `erl`. That is:
+
+```bash
+erl -emu_type lcnt
+erl -emu_flavor emu -emu_type debug
+```
+
+When running valgrind, asan or gcov those tools create special output files that
+need to be processed. To work with these files there is a special `erl` program
+called `cerl` that is only available in the source tree. You can read more about
+it in the [cerl section](#cerl) later in this guide.
+
+If you want to run the tests with a special flavor or type, the easiest way to
+do that is by setting the TYPE or FLAVOR when calling make. For example if you
+want to run the emulator tests using the debug emulator you can do it like this:
+
+```bash
+make emulator_test TYPE=debug
+```
+
+*NOTE*: Before you run tests using a TYPE or FLAVOR you need to build the **entire**
+Erlang/OTP repo using that TYPE or FLAVOR. That is `make TYPE=debug` for the example
+above.
+
+### cerl
+
+`cerl` is a program available in `$ERL_TOP/bin/` that has a number of features
+useful when developing the Erlang run-time system. It work just as normal `erl`,
+but accepts a couple of extra command line switches. Any other command line arguments
+passed to `cerl` will be passed on the Erlang as normal. The extra command line
+switches are:
+
+* -debug
+  * Start a debug run-time system.
+* -lcnt
+  * Start a lock count run-time system.
+* -valgrind
+  * Start valgrind with the correct settings and use the `valgrind` [type](types-and-flavors).
+  * Set environment variable `VALGRIND_LOG_XML` to true if want xml valgrind logs.
+  * Set environment variable `VALGRIND_LOG_DIR` to where you want valgrind logs.
+  * Set environment variable `VALGRIND_MISC_FLAGS` for any extra valgrind flags you want to pass.
+* -asan
+  * Start [Clang Address Sanitizer](https://clang.llvm.org/docs/AddressSanitizer.html)
+    with the the correct settings and use the `asan` [type](types-and-flavors).
+  * Set environment variable `ASAN_LOG_DIR` to where you want the logs.
+  * Set environment variable `ASAN_OPTIONS` for any extra asan options you want to pass.
+* -gcov
+  * Start a gcov run-time system.
+* -gdb
+  * Start an Emacs gdb debugging session. Can be combined with -debug.
+* -core /path/to/core/file
+  * Start an Emacs gdb debugging session for the core specified.
+* -rgdb
+  * Start a gdb debugging session in the current terminal. Can be combined with -debug.
+* -rcore /path/to/core/file
+  * Start a gdb debugging session in the current terminal for the core specified.
+* -lldb
+  * Start a lldb debugging session in the current terminal.
+* -rr
+  * Start Erlang under [rr](https://rr-project.org/) to record all events. Can be combined with -debug.
+* -rr replay [session]
+  * Load a recording session using `rr replay`, if no session is specified the latest run session is laoded.
+
+If you want to run tests using `cerl` (for example if you want to run asan on
+the nif_SUITE in emulator) you cannot use the `make test` approach to testing
+as that uses `ct_run` under the hood and `ct_run` does not support customizing
+the emulator start script. Instead you need to use the approach described in
+[Run tests with Address Sanitizer](INSTALL.md#run-tests-with-address-sanitizer).
+
+
+### Static analysis
+
+From the top level of Erlang/OTP you can run:
+
+```bash
+make xmllint
+make dialyzer
+make format-check
+```
+
+This will check that the documentation is correct and that there are no
+dialyzer errors. See also [Validating documentation](#validating-documentation)
+for more details.
+
+## Running test cases
+
+There is a detailed description about how to run tests in [TESTING.md](TESTING.md).
+
+## Writing and building documentation
+
+Most of the Erlang/OTP documentation is written in XML files located in
+`lib/$APPLICATION_NAME/doc/src`. The format of the XML is described in the
+[ErlDocgen User's Guide](https://www.erlang.org/doc/apps/erl_docgen/users_guide.html).
+
+There is also some documentation that is written using [edoc](https://www.erlang.org/doc/man/edoc.html).
+
+To view the documentation the simplest way is to release it. *NOTE*: The Erlang/OTP
+repository needs to have been [built](#building-and-testing) before you can build
+the documentation.
+
+```bash
+make release_docs
+```
+
+and then you can view `release/*/doc/index.html` in your favourite browser and
+make sure that it looks nice.
+
+This takes a while though and to speed up the edit-view cycle you can either
+limit what parts of the documentation is built using `DOC_TARGETS`. For example:
+
+```bash
+make release_docs DOC_TARGETS=html
+```
+
+The different `DOC_TARGETS` built are `html`, `man`, `pdf` and `chunks`.
+
+You can also build the docs only for a single application. For example:
+
+```bash
+cd lib/stdlib/doc/src && make local_docs DOC_TARGETS=html
+```
+
+and then view the results at `lib/stdlib/doc/html/index.html`.
+
+### Validating documentation
+
+In order to make sure that the documentation is correct you need to also
+validate it. Just building the documentation does not mean that it is
+correct. There are two steps that you need to do in order to validate
+the docs.
+
+First run the `xmllint`. This makes sure that the xml follows the
+[Erlang/OTP dtd](https://www.erlang.org/doc/apps/erl_docgen/overview.html)
+and does some extra checks to make sure all links are correct.
+
+You run the xmllint like this:
+
+```bash
+make xmllint                    # Run it at the top level
+cd lib/stdlib && make xmllint   # Run it for only a single application
+```
+
+When the xml has been verified you also need to make sure that there
+are no broken links in the documentation. This is done by running
+[`otp_html_check`](https://github.com/erlang/otp/blob/master/scripts/otp_html_check).
+
+You run `otp_html_check` like this:
+
+```bash
+make release_docs DOC_TARGETS="html pdf"  # First we need to release the pdf+html docs
+$ERL_TOP/scripts/otp_html_check $(pwd)/release/$($ERL_TOP/erts/autoconf/config.guess) doc/index.html
+```
+
+The output of `otp_html_check` will print a list of broken links and anchors, for example:
+
+```text
+**** Files not used (that I can see)
+....
+
+**** Broken links
+
+Broken Link: /lib/kernel-8.3.1/doc/html/inet.html -> "/lib/kernel-8.3.1/doc/html/files.html"
+
+**** References to missing anchors
+
+Missing Anchor: "/lib/kernel-8.3.1/doc/html/files.html#native_name_encoding-0" from /lib/kernel-8.3.1/doc/html/inet.html
+Missing Anchor: "/lib/kernel-8.3.1/doc/html/inet.html#type-ip_addres" from /lib/kernel-8.3.1/doc/html/inet.html
+```
+
+The `Files not used` section is mostly used to debug the documentation build
+process, so it can be ignored most of the time. The other to sections should
+however be empty for the documentation to be correct.
+
+All this validation is also done by [Github Actions](#github-actions).
+
+## Github Actions
+
+Erlang/OTP uses [Github Actions](https://github.com/features/actions) as a
+preliminary CI to check that nothing fundamental has been broken by the change.
+
+You can enable Github Actions on your own github fork in order to run the tests
+before opening a PR to the main repository.
+
+Github Actions does too many checks to list them all but the primary ones are:
+
+* Build on Ubuntu Linux and Windows
+* Cross build to Debian Linux on powerpc and iOS
+* Build and validate documentation
+* Run dialyzer on all of Erlang/OTP
+* Run the tests of the changed application
+
+Each run generates a bunch of artifacts. The most important ones are:
+
+* `test_results`
+  * An archive containing all the logs from all tests that have been run.
+    Navigate to `make_test_dir/ct_logs/index.html` within the archive to
+    view the Common Test summary of the tests.
+* `otp_win32_installer`
+  * A windows installer with the changes you have made.
+* `otp_doc_html`
+  * The HTML docs with the changes you have made.
+
+### Debugging Github Actions failures
+
+Debugging Github Actions is at best a very time-consuming endevour. So if there
+is an error in the build or tests that you don't easily understand I would
+recommend that you try to reproduce it locally.
+
+This is of course not always possible, for instance if it only fails on Windows
+and you do not have access to a Windows machine, but it may the worth it as the
+leadtime of re-running a test is roughly 30 minutes. See the [other sections of
+this guide](#developing-erlang-otp) for details on how to build and run tests
+locally.
+
+If testcases fail when running Github Actions, it is best to start by inspecting
+the logs of the test runs. The logs are attached to the finished run as
+`test_results`. You will find more details about why a testcase failed in
+the logs.
+
+## Using Docker
+
+In order to get a reproduceable environment for building and testing you can use
+[docker](https//www.docker.com). If you are not familiar with how to use it I
+would recommend [reading up a bit](https://www.docker.com/get-started) and trying
+some simple examples yourself before using it to build and test Erlang/OTP.
+
+There is a pre-built ubuntu base image available on github, but you can also
+build it locally if you want to.
+
+Using the pre-built base you build an image like this:
+
+```bash
+docker login docker.pkg.github.com
+git archive --prefix otp/ -o .github/otp.tar.gz HEAD
+docker build -t my_otp_image -f .github/dockerfiles/Dockerfile.64-bit .github/
+```
+
+This will fetch the ubuntu base image and build a 64-bit Erlang/OTP. You need to
+[login to the github container registry](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry)
+in order to fetch the base image. If you want to build the base image locally
+you can do that like this:
+
+```bash
+docker built -t docker.pkg.github.com/erlang/otp/ubuntu-base \
+  --build-arg BASE=ubuntu --build-arg USER=otptest --build-arg uid=$(id -u) \
+  --build-arg GROUP=uucp --build-arg gid=$(id -g) \
+  -f .github/dockerfiles/Dockerfile.ubuntu-base .github/
+```
+
+Which approach is fastest depends on the speed of your internet connection.
+
+When you have built the docker image you can run tests in it like this:
+
+```bash
+docker run my_otp_image "make stdlib_test"
+```
+
+or if you want to persist the test results outside the container:
+
+```bash
+mkdir -m 777 make_test_dir   ## The 777 mode is needed to avoid permission problems
+docker run --init -v $PWD/make_test_dir:/buildroot/otp/lib/stdlib/make_test_dir \
+  my_otp_image "make stdlib_test"
+```
+
+The Common Test logs will be placed in `make_test_dir/ct_logs`.
+
+### Gidpod.io or VSCode dev container
+
+This git repository is also prepared to run using [Gitpod](https://gitpod.io/) or
+[VSCode Devcontainer](https://code.visualstudio.com/docs/remote/containers).
+
+The support for these environments is very early so it will be a bit unstable.
+
+To access the gitpod for Erlang/OTP you just navigate to
+[https://gitpod.io/#https://github.com/erlang/otp](https://gitpod.io/#https://github.com/erlang/otp).
+
+When using a VSCode dev container, you only need to open [VSCode](https://code.visualstudio.com/)
+in the Erlang/OTP repository and you should get a popup that asks if you want to
+run in a dev container.
+
+The gitpod and dev container both use the base ubuntu image built in [Using Docker](#using-docker).
+So it should be possible to run all tests inside the containers with all test
+dependencies available.
+
+*WARNING*: Using VSCode dev container on macOS can be very slow because of limitations
+in the filesystem. So I would recommend either using gitpod or just work locally without
+the dev container on macOS.

+Cross Compiling Erlang/OTP - IOS
+====================================
+
+Introduction
+------------
+
+This document describes how to cross compile Erlang/OTP to iOS platforms. iOS has the peculiarity that it does not support the creation of shared libraries. So the build process needs to be amended to generate statically linkable and executable Erlang binaries.
+
+### Get Xcode Tools ###
+
+iOS binaries can only be cross-compiled from Apple macOS computers. For compilation the Xcode tools must be used.
+### Environment Variables ###
+
+In order to inform the build system that it should generate the static linkable `libbeam.a` add the following environment variable during configuration and compilation:
+
+    $ export RELEASE_LIBBEAM=yes
+
+### Configure Erlang/OTP ###
+
+    To build without without OpenSSL support, run `configure` like this:
+    
+    $ ./otp_build configure \
+         --xcomp-conf=./xcomp/erl-xcomp-arm64-ios.conf  \
+         --without-ssl
+
+
+To build with OpenSSL statically linked, run `configure` like this (note that 1.1.1k works, but needs a manual patch in ios cross build config to include engines):
+
+    $ ./otp_build configure \
+         --xcomp-conf=./xcomp/erl-xcomp-arm64-ios.conf  \
+         --with-ssl=/path/to/libcrypto.a \
+         --disable-dynamic-ssl-lib
+
+
+### Compile Erlang/OTP ###
+
+    $ ./otp_build boot
+
+### Linking a binary with your App ###
+    
+To use the resulting `libbeam.a` it needs to be packaged into a Xcode `.xcframework` package together with all other required `.a` files. These include:
+
+* `libbeam.a`
+* `libz.a`
+* `libcrypto.a`
+
+Basically all .a files that have been generated by the build.
+
+One way of creating a combined archive out of all of these is to use `libtool`:
+
+    $ libtool -static -o liberlang.a /Path/to/libbeam.a /Path/to/....a
+
+This list should also include static nifs you want to include:
+
+Finally packaging the archive into a `.xcframework` directory:
+
+    $ xcodebuild -create-xcframework -output ./liberlang.xcframework -library liberlang.a
+
+If you're building for multiple iOS targets (e.g. simulator and phone):
+
+    $ xcodebuild -create-xcframework -output ./liberlang.xcframework -library /Path/to/phonelib/liberlang.a -library /Path/to/simulatorlib/liberlang.a
+
+## Starting Erlang
+
+To execute erlang from within an iOS project a native C/C++ wrapper is needed that can call the function:
+
+    erl_start(int argc, char *argv[]); 
+    
+An example call could look like this: 
+
+    $ const char *args[] = {
+            "my_main",
+            "-sbwt",
+            "none",
+            "--",
+            "-root",
+            root_dir.c_str(),
+            "-progname",
+            "erl",
+            "--",
+            "-home",
+            home_dir.c_str(),
+            "--",
+            "-kernel",
+            "shell_history",
+            "enabled",
+            "--",
+            "-start_epmd",
+            "false",
+            "-elixir",
+            "ansi_enabled",
+            "true",
+            "-noshell",
+            "-s",
+            "elixir",
+            "start_cli",
+            "-mode",
+            "interactive",
+            "-config",
+            config_path.c_str(),
+            "-boot",
+            boot_path.c_str(),
+            "-boot_var",
+            "RELEASE_LIB",
+            lib_path.c_str(),
+            "--",
+            "--",
+            "-extra",
+            "--no-halt",
+    };
+
+    erl_start(sizeof(args) / sizeof(args[0]), (char **)args);
+
+### Reference Example
+
+At the time of writing (October 2021) there is a full reference iOS application available at https://github.com/elixir-desktop/ios-example-app.
+
+An implementation of the native wrapper can be viewed at https://github.com/elixir-desktop/ios-example-app/blob/main/native-lib.cpp.

-### Convenience for running tests without the release and configuration steps
-
-It can be convenient to run tests with a single command. This way, one
-do not need to worry about missing to run `make release_tests` after
-changing a test suite. The `make test` command can be used for this
-purpose. The `make test` command works when the current directory

-*(Warning)* Some test cases do not run correctly or cannot be run at

-test specific C code to be compiled) because `make test` runs tests
-directly by invoking the `ct_run` command instead of using the `ts`

 There are several examples [on the website](http://erlang.org/faq/getting_started.html) to help you get started. The below example defines a function `world/0` that prints "Hello, world" in the Erlang shell:

 ```erlang
 -module(hello).
 -export([world/0]).
 
 world() -> io:format("Hello, world\n").
 ```
+
 Save the file as `hello.erl` and run `erl` to enter the Erlang shell to compile the module.

+%%% To avoid having to extend the number of distribution flags from 64
+%%% to 128, a scheme for garbage collection of the flags was
+%%% introduced in OTP 25.
+%%%
+%%% In OTP 25, ?DFLAG_MANDATORY_25_DIGEST was introduced as a synonym
+%%% for the flags defined by ?MANDATORY_DFLAGS_25. OTP 25/26 will
+%%% accept the old flags to support communication with 24 and earlier,
+%%% as well as ?DFLAG_MANDATORY_25_DIGEST.
+%%%
+%%% OTP 27 will make ?DFLAG_MANDATORY_25_DIGEST mandatory, meaning that an
+%%% OTP 27 node can only communicate with OTP 25 and higher.
+%%%
+%%% An OTP 27 node will also introduce the new flag
+%%% ?DFLAG_MANDATORY_27_DIGEST:
+%%%
+%%% * If ?DFLAG_MANDATORY_27_DIGEST is set, it means that all bit
+%%%   numbers defined by ?MANDATORY_DFLAGS_25, as well as the bit
+%%%   number defined by ?DFLAG_MANDATORY_25_DIGEST and any other bits
+%%%   made mandatory in OTP 26/27, lose their previous meanings. New
+%%%   meanings can then be assigned to those bit numbers as
+%%%   needed. (This is for communication between nodes from OTP 27 and
+%%%   up.)
+%%%
+%%% * If ?DFLAG_MANDATORY_27_DIGEST is not set, then
+%%%   ?DFLAG_MANDATORY_25_DIGEST must be set and all bit numbers
+%%%   defined by ?MANDATORY_DFLAGS_25 are ignored. (This is for
+%%%   communication between an OTP 27 node and an OTP 25/26 node.)

+	    An unlink operation made by a process that terminated
+	    before the unlink operation completed, i.e., before it
+	    had received an unlink-ack signal from the linked
+	    process, caused an exit signal to erroneously be sent
+	    from the terminating process to the process being
+	    unlinked. This exit signal would most often be ignored by
+	    the receiver, but if the receiver of the exit signal
+	    concurrently set up a new link, it could receive the exit
+	    signal with the actual exit reason of the terminating
+	    process instead of a <c>noproc</c> exit reason. It is

+	    The signal queue of a process with
+	    message_queue_data=off_heap* has been optimized to allow
+	    parallel reception of signals from multiple processes. </p>
+          <p>
+	    This is possible to do as Erlang only guarantees that
+	    signals (i.e., message signals and non-message signals)
+	    sent from a single process to another process are ordered
+	    in send order. However, there are no ordering guarantees
+	    for signals sent from different processes to a particular
+	    process. Therefore, several processes can send signals in
+	    parallel to a specific process without synchronizing with
+	    each other. However, such signal sending was previously
+	    always serialized as the senders had to acquire the lock
+	    for the outer signal queue of the receiving process. This
+	    parallel signal sending optimization yields much better
+	    scalability for signal sending than what was previously
+	    possible, see
+	    https://erlang.org/bench/sigq_bench_result.html for
+	    benchmark results.</p>
+          <p>
+	    * Information about how to enable the
+	    message_queue_data=off_heap setting can be found in the
+	    documentation of the function erlang:process_flag/2.</p>

+	    An unlink operation made by a process that terminated

+	    from the terminating process to the process being

+	    signal with the actual exit reason of the terminating

+	    An unlink operation made by a process that terminated

+ * While the compiler is good eliminating redundant type tests and simplifying

+ * always worthwhile to add new variants.
+ * 
+ * The idea behind this module is to allow minor optimizations _inside_
+ * instructions based on what we know about their operand types. For example,
+ * when we know that the source passed to `is_tagged_tuple` is always boxed, we
+ * can skip the boxed check.

+     * 2. Ensures that all signals that the caller might have sent to

+     *
+     *    This is, however, not strictly necessary. process_info() is

+     *    signals before gathering the information, outstanding signals
+     *    from the caller to itself will not be part of the result.
+     *    This would not be wrong, but perhaps surprising for the user.
+     *    We continue doing it this way for now, since this is how it
+     *    has been done for a very long time. We should, however,
+     *    consider changing this in a future release, since this signal

- * Description:	Memory allocation trace. The trace is sent over a

- *
- *              The trace format is not intended to be documented.
- *              Instead a library for parsing the trace will be
- *              distributed. This in order to more easily be able
- *              to make changes in the trace format. The library
- *              for parsing the trace is currently not included in
- *              the OTP distribution, but will be in the future.

+ * The code below is used to deal with intercepting the execution of a process
+ * at the start of a function. It is used by tracing and nif loading.
  *
  * In the interpreter this is solved by simply writing a new instruction as
  * the first instruction in a function. In asm mode it is not as simple as
  * our code changes have to be to executing native code.
  *
- * The solution is as follows:
+ * On x86, the solution is as follows:
  *
  *   When emitting a function the first word (or function prologue) is:
- *      0x0: jmp 6
- *      0x2: ERTS_ASM_BP_FLAG_NONE
- *      0x3: relative near call
- *      0x4: &genericBPTramp
+ *      0x0: short jmp 6
+ *      0x2: nop
+ *      0x3: relative near call to shared breakpoint fragment
  *      0x8: actual code for function
  *
- *   When code starts to execute it will simply see the "jmp 6" instruction
- *   which skips the prologue and starts to execute the code directly.
+ *   When code starts to execute it will simply see the `short jmp 6`
+ *   instruction which skips the prologue and starts to execute the code
+ *   directly.
  *
- *   When we want to enable a certain breakpoint we set the jmp target to
- *   be 1 (which means it will land on the call instruction) and will call
- *   genericBPTramp. genericBPTramp is a label at the top of each module
- *   that contains trampolines for all flag combinations.
+ *   When we want to enable a certain breakpoint we set the jmp target to be 1,
+ *   which means it will land on the call to the shared breakpoint fragment.
+ *   This fragment checks the current `breakpoint_flag` stored in the
+ *   ErtsCodeInfo of this function, and then calls `erts_call_nif_early` and
+ *   `erts_generic_breakpoint` accordingly.
  *
- *   genericBPTramp:
- *      0x0: ret
- *      0x10: jmp call_nif_early
- *      0x20: call generic_bp_local
- *      0x30: call generic_bp_local
- *      0x35: jmp call_nif_early
+ *   Note that the update of the branch and `breakpoint_flag` does not need to
+ *   be atomic: it's fine if a process only sees one of these being updated, as
+ *   the code that sets breakpoints/loads NIFs doesn't rely on the trampoline
+ *   being active until thread progress has been made.
  *
- *   Note that each target is 16 byte aligned. This is because the call target
- *   in the function prologue is updated to target the correct place when a flag
- *   is updated. So if CALL_NIF_EARLY is set, then it is updated to be
- *   genericBPTramp + 0x10. If BP is set, it is updated to genericBPTramp + 0x20
- *   and the combination makes it be genericBPTramp + 0x30.
- */
+ * The solution for AArch64 is similar. */

+To aid debuggers and sampling profilers, we support running Erlang code with

+leaving it, including on tail calls as the callee will immediately push the

-Introduction
-------------
+# Tracing
+
+## Implementation
+### Call, return, and exception tracing
+
+Tracing is implemented by setting breakpoints in the traced functions,
+and sending the appropriate trace messages when they're hit.
+
+* Call trace messages are sent immediately.
+* Return tracing pushes a frame to the stack which _returns to_ an
+  instruction that sends a trace message when encountered.
+* Exception tracing also pushes a frame to the stack, but will only send
+  a trace message if we encounter it in stack scanning while throwing an
+  exception.
+
+This means that one must be careful not to use return or exception tracing
+on functions that never return, as each call pushes a frame that will
+never be removed.
+
+Another limitation is that since the breakpoint is in the _callee_ and not
+the _caller_, we're limited to the information we have on function ingress.
+This means that we can't actually tell who called us: since we're limited
+to inspecting the stack we can only say where we're _going to return to_,
+which is not quite the same thing.
+
+As an illustration, when the `caller` option is enabled all trace messages
+from `bar/1`  will say that they were called from `foo/0`, even though it
+went through a bunch of other functions on the way:
+
+    foo() ->
+        lots(),
+        ok.
+    
+    lots() ->
+        'of'().
+    
+    'of'() ->
+        indirections().
+    
+    indirections() ->
+        bar(10).
+    
+    bar(0) ->
+        done;
+    bar(N) ->
+        bar(N - 1).
+
+### Export tracing
+
+In the interpreter, breakpoints are set inside the code trampoline for
+export entries, and their address vector is updated to point to them.
+This way, only remote calls will hit the breakpoint while local calls to
+the same function are left alone, but it otherwise acts the same way as
+local breakpoints.
+
+Things get a bit more involved in the JIT. See `BeamAsm.md` for more
+details.

+# How to update the Ryu version used by Erlang
+
+Last commit taken : 844864ac213bdbf1fb57e6f51c653b3d90af0937
+
+## The basic changes to the Ryu library
+
+To work with the Erlang VM, Ryu has been changed in three important ways. These
+changes have been marked with a `//CHANGE_FOR_ERLANG` comment explaining them in
+the code.
+
+1. We only kept the bare minimum files needed to generate a double to string with the shortest algorithm, with the widest lookup table
+2. We deleted the code producing the final string, this is handled using a modified version of to_chars from the MS STL. <https://github.com/microsoft/STL/blob/8f4c8163775d665d80642044ce27c4bc696127ce/stl/inc/xcharconv_ryu.h#L1302>
+3. All other unneeded code has been deleted
+
+This is build with our own makefile.
+
+Some of the more minor difference:
+
+- the Zero case in common.h is changed to correspond to erlang fixed point version
+- the MS STL pointer check are not here. Erlang generate a 256 bytes buffer, we only need 30 maximum. Beware what this mean when refactoring.

+//   from a lookup table. We know that the 64-bit factor only has 55
+//   significant bits (i.e., the 9 topmost bits are zeros). The 128-bit
+//   factor only has 124 significant bits (i.e., the 4 topmost bits are
+//   zeros).
+// Shift:
+//   In principle, the multiplication result requires 55 + 124 = 179 bits to
+//   represent. However, we then shift this value to the right by j, which is
+//   at least j >= 115, so the result is guaranteed to fit into 179 - 115 = 64
+//   bits. This means that we only need the topmost 64 significant bits of
+//   the 64x128-bit multiplication.
+//
+// There are several ways to do this:
+// 1. Best case: the compiler exposes a 128-bit type.
+//    We perform two 64x64-bit multiplications, add the higher 64 bits of the
+//    lower result to the higher result, and shift by j - 64 bits.
+//
+//    We explicitly cast from 64-bit to 128-bit, so the compiler can tell
+//    that these are only 64-bit inputs, and can map these to the best
+//    possible sequence of assembly instructions.
+//    x64 machines happen to have matching assembly instructions for
+//    64x64-bit multiplications and 128-bit shifts.
+//
+// 2. Second best case: the compiler exposes intrinsics for the x64 assembly
+//    instructions mentioned in 1.
+//
+// 3. We only have 64x64 bit instructions that return the lower 64 bits of
+//    the result, i.e., we have to use plain C.
+//    Our inputs are less than the full width, so we have three options:
+//    a. Ignore this fact and just implement the intrinsics manually.
+//    b. Split both into 31-bit pieces, which guarantees no internal overflow,
+//       but requires extra work upfront (unless we change the lookup table).
+//    c. Split only the first factor into 31-bit pieces, which also guarantees
+//       no internal overflow, but requires extra work since the intermediate
+//       results are not perfectly aligned.

+     * extra bits, for lengths 131 to 257. The longest fixed distance codes are
+     * 5 bits plus 13 extra bits, for distances 16385 to 32768. The longest

+     *
+     * sym_buf starts one-fourth of the way into pending_buf. So there are
+     * three bytes in sym_buf for every four bytes in pending_buf. Each symbol
+     * in sym_buf is three bytes -- two for the distance and one for the
+     * literal/length. As each symbol is consumed, the pointer to the next
+     * sym_buf value to read moves forward three bytes. From that symbol, up to
+     * 31 bits are written to pending_buf. The closest the written pending_buf
+     * bits gets to the next sym_buf symbol to read is just before the last
+     * code is written. At that time, 31*(n-2) bits have been written, just
+     * after 24*(n-2) bits have been consumed from sym_buf. sym_buf starts at
+     * 8*n bits into pending_buf. (Note that the symbol buffer fills when n-1
+     * symbols are written.) The closest the writing gets to what is unread is
+     * then n+14 bits. Here n is lit_bufsize, which is 16384 by default, and
+     * can range from 128 to 32768.
+     *
+     * Therefore, at a minimum, there are 142 bits of space between what is
+     * written and what is read in the overlain buffers, so the symbols cannot
+     * be overwritten by the compressed data. That space is actually 139 bits,
+     * due to the three-bit fixed-code block header.
+     *
+     * That covers the case where either Z_FIXED is specified, forcing fixed
+     * codes, or when the use of fixed codes is chosen, because that choice
+     * results in a smaller compressed block than dynamic codes. That latter
+     * condition then assures that the above analysis also covers all dynamic
+     * blocks. A dynamic-code block will only be chosen to be emitted if it has
+     * fewer bits than a fixed-code block would for the same set of symbols.
+     * Therefore its average symbol length is assured to be less than 31. So

 I think you should test the patterns you are going to use. You can easily modify the test-harness to generate tests for your intended patterns to check for compliance.

+    <h1>Message Send/Receive Benchmark Result Viewer</h1>
+    <p>
+      This page generates graphs from data produced by the Message Send/Receive Benchmark which is defined in the function <code>parallel_messages_SUITE:test_throughput_benchmark/1</code> (see "<code>$ERL_TOP/erts/test/parallel_messages_SUITE.erl</code>").
+    </p>
+    <p>
+      Note that one can paste results from several benchmark runs into the field below. Results from the same scenario but from different benchmark runs will be relabeled and plotted in the same graph automatically.
+    </p>
+    <p>
+      Note also that that lines can be hidden by clicking on the corresponding label.
+    </p>
+    Paste the generated data in the field below and press the Render button:

+	    Own Id: OTP-17820</p>
+        </item>
+        <item>
+	    <p>Starting in OTP 24, when a fun was created and
+	    immediately used, it would be inlined. An unintended
+	    consequence of the inlining was that what would be a
+	    <c>function_clause</c> exception without the inlining
+	    would now be a rather confusing <c>case_clause</c>
+	    exception. This has been corrected, so that
+	    <c>function_clause</c> exceptions remain
+	    <c>function_clause</c> exceptions in inlined code.</p>

+          <p>
+	    If a default record field initialization (<c>_ =
+	    Expr</c>) was used even though all records fields were
+	    explicitly initialized, <c>Expr</c> would not be
+	    evaluated. That would not be a problem, except when
+	    <c>Expr</c> would bind a variable subsequently used, in
+	    which case the compiler would crash.</p>
+          <p>
+	    As an example, if record <c>#r{}</c> is defined to have
+	    only one field <c>a</c>, the following code would crash
+	    the compiler:</p>
+          <p>
+	    <c>#r{a=[],_=V=42}, V</c></p>
+          <p>
+	    To fix that problem, the compiler will make sure that
+	    <c>Expr</c> is always evaluated at least once. The
+	    compiler will now rewrite the example to essentially:</p>
+          <p>
+	    <c>V=42, #r{a=[]}, V</c></p>

 Invariants on the Structure and Format of BEAM SSA
 ==================================================
 
+Exception Handling
+------------------
+
+The translation of a `try`-`catch` expression into BEAM SSA has the
+following structure:
+
+    @tag = new_try_tag `try`
+	br @tag, ^protected_block0, ^landing_pad_block
+
+	protected_block0:
+	  @success0 = ... % Something that could raise an exception
+	  br @success0, ^protected_block1, ^landing_pad_block
+
+	...
+
+	protected_blockN:
+	  % The end of the protected code
+	  @ignored0 = kill_try_tag @tag
+      br ^after_try_catch
+
+	landing_pad_block:
+	  @aggregate = landingpad try, @tag
+	  @class  = extract @aggregate, `0` % The error class
+	  @reason = extract @aggregate, `1` % The reason
+	  @stk    = extract @aggregate, `2` % The stack trace
+	  @ignored1 = kill_try_tag @tag
+	  %% Pattern matching on @class, @reason, and @stk is done here
+	  %% to send control to the appropriate catch clause
+      br ^after_try_catch
+
+    after_try_catch:
+      % Normal execution continues
+
+The following invariants must hold for the SSA:
+
+ * All code that can cause an exception in one of the protected blocks
+   must have explicit control flow edges to the landing pad block. If
+   there are no edges to the landing pad block except from the block
+   containing the `new_try_tag`, the compiler will remove the
+   redundant exception handler.
+ * The extraction of the class, reason and stack trace from the result
+   of the `landingpad` instruction must be done in that
+   order. Omitting the extraction of elements which are unused is
+   allowed.
+ * Both the landing pad block and the final protected block must end
+   with a `kill_try_tag` instruction. Trying to share the
+   `kill_try_tag` epilogue between the last protected block and the
+   landing pad is unlikely to work.
+
+The translation of an old-style `catch` expression into BEAM SSA has
+the following structure:
+
+    @tag = new_try_tag `try`
+	br @tag, ^protected_block0, ^landing_pad_block
+
+	protected_block0:
+	  @success0 = ... % Something that could raise an exception
+	  br @success0, ^protected_block1, ^landing_pad_block
+
+	...
+
+	protected_blockN:
+	  % The end of the protected code
+	  @successful_result = .... % The result of a successful computation
+	  br ^common_end_of_catch
+
+	landing_pad_block:
+	   @aggregate = landingpad catch, @tag
+	   @catched_val = extract @ssa_agg, `0`
+	   br ^common_end_of_catch
+
+	common_end_of_catch:
+	  @tmp = phi { @catched_val, ^landing_pad_block },
+	             { @successful_result, ^protected_blockN }
+	  @result_of_catch_expr = catch_end @tag, @tmp
+
+Just as for a `try`-`catch` expression all code that can cause an
+exception in one of the protected blocks must have explicit control
+flow edges to the landing pad block.
+
+Exception Re-issuing
+--------------------
+
+A typical user-written `try`-`catch` expression will catch a subset of
+all possible exception classes and reasons and leave unhandled
+exceptions to a handler further up the call stack. Re-issuing an
+exception is done with the `resume` instruction. The `resume` must
+come after the `kill_try_tag` instruction in the program flow. For
+example, if the [example in the Exception Handling Section](#exception-handling)
+was to only handle user `throws`, the relevant blocks would look like this:
+
+	landing_pad_block:
+	  @aggregate = landingpad `try`, @tag
+	  @class  = extract @aggregate, `0` % The error class
+	  @reason = extract @aggregate, `1` % The reason
+	  @stk    = extract @aggregate, `2` % The stack trace
+	  @ignored1 = kill_try_tag @tag
+	  @is_throw = bif:'=:=' @class, `throw`
+      br @is_throw ^first_block_of_throw_handler, ^reissue
+
+	first_block_of_throw_handler:
+	  %% Handle the user-defined throw
+
+	reissue:
+	  @tmp = resume @stk, @reason
+	  ret @tmp
+

+%%% This sub pass is run once after the main type sub pass
+%%% to annotate more instructions with integer ranges.
+%%%
+%%% The main type sub pass annotates certain instructions with
+%%% their types to help the JIT generate better code.
+%%%
+%%% Example:
+%%%
+%%%   foo(N0) ->
+%%%       N1 = N0 band 3,
+%%%       N = N1 + 1,        % N1 is in 0..3
+%%%       element(N,
+%%%            {zero,one,two,three}).
+%%%
+%%% The main type pass is able to figure out the range for `N1` but
+%%% not for `N`. The reason is that the type pass iterates until it
+%%% reaches a fixpoint. To guarantee that it will converge, ranges for
+%%% results must only be calculated for operations that retain or
+%%% shrink the ranges of their arguments.
+%%%
+%%% Therefore, to ensure convergence, the main type pass can only
+%%% safely calculate ranges for results of operations such as `and`,
+%%% `bsr`, and `rem`, but not for operations such as `+`, '-', '*',
+%%% and `bsl`.
+%%%
+%%% This sub pass will start from the types found in the annotations
+%%% and propagate them forward through arithmetic instructions within
+%%% the same function.
+%%%
+%%% For the example, this sub pass adds a new annotation for `N`:
+%%%
+%%%   foo(N0) ->
+%%%       N1 = N0 band 3,
+%%%       N = N1 + 1,        % N1 is in 0..3
+%%%       element(N,         % N is in 1..4
+%%%           {zero,one,two,three}).
+%%%
+%%% With a known range and known tuple size, the JIT is able to remove
+%%% all range checks for the `element/2` instruction.

+%%% Here follows an abstract data structure to help us handle Erlang's
+%%% implicit matching that occurs when a variable is bound more than
+%%% once:
+%%%
+%%%     X = Expr1(),
+%%%     X = Expr2()
+%%%
+%%% What is implicit in Erlang, must be explicit in Core Erlang; that
+%%% is, repeated variables must be eliminated and explicit matching
+%%% must be added. For simplicity, examples that follow will be given
+%%% in Erlang and not in Core Erlang. Here is how the example can be
+%%% rewritten in Erlang to eliminate the repeated variable:
+%%%
+%%%     X = Expr1(),
+%%%     X1 = Expr2(),
+%%%     if
+%%%         X1 =:= X -> X;
+%%%         true -> error({badmatch,X1})
+%%%     end
+%%%
+%%% To implement the renaming, keeping a set of the variables that
+%%% have been bound so far is **almost** sufficient. When a variable
+%%% in the set is bound a again, it will be renamed and a `case` with
+%%% guard test will be added.
+%%%
+%%% Here is another example:
+%%%
+%%%     (X=A) + (X=B)
+%%%
+%%% Note that the operands for a binary operands are allowed to be
+%%% evaluated in any order. Therefore, variables bound on the left
+%%% hand side must not referenced on the right hand side, and vice
+%%% versa. If a variable is bound on both sides, it must be bound
+%%% to the same value.
+%%%
+%%% Using the simple scheme of keeping track of known variables,
+%%% the example can be rewritten like this:
+%%%
+%%%     X = A,
+%%%     X1 = B,
+%%%     if
+%%%         X1 =:= X -> ok;
+%%%         true -> error({badmatch,X1})
+%%%     end,
+%%%     X + X1
+%%%
+%%% However, this simple scheme of keeping all previously bound variables in
+%%% a set breaks down for this example:
+%%%
+%%%     (X=A) + fun() -> X = B end()
+%%%
+%%% The rewritten code would be:
+%%%
+%%%     X = A,
+%%%     Tmp = fun() ->
+%%%               X1 = B,
+%%%               if
+%%%                   X1 =:= X -> ok;
+%%%                   true -> error({badmatch,X1})
+%%%               end
+%%%           end(),
+%%%     X + Tmp
+%%%
+%%% That is wrong, because the binding of `X` created on the left hand
+%%% side of `+` must not be seen inside the fun. The correct rewrite
+%%% would be like this:
+%%%
+%%%     X = A,
+%%%     Tmp = fun() ->
+%%%               X1 = B
+%%%           end(),
+%%%     X + Tmp

+%%% information in a record so that we can remove `X` from the known

+	    The information in error messages are increased.</p>
+          <p>
+	    Previously the error was signaled with en error class
+	    exception <c>badarg</c>, <c>notsup</c> or <c>error</c>,
+	    and also in some more ways like an other exception or a
+	    return value in a non-standardized format.</p>
+          <p>
+	    Now it is an error-class exception
+	    <c>{notsup|badarg|error, InfoFromCfile,
+	    Description::string()}</c>.</p>
+          <p>
+	    The <c>InfoFromCfile</c> is a term with name and line
+	    number of the C-file where the error was found. This is
+	    primarily intended for a crypto maintainer or an advanced
+	    user to find the cause of complicated errors - maybe in
+	    crypto itself. The contents of that term might be changed
+	    in the future.</p>
+          <p>
+	    The <c>Description</c> is a clear text string that
+	    describes the error. In case of <c>badarg</c> and
+	    <c>notsup</c> the intention is that it should help the
+	    user to find the cause ("Bad key size" as an example).
+	    Specially for some <c>error</c> that are unlikely, the
+	    string may not be possible to understand without deep
+	    knowledge of the underlying cryptolib. Such messages are
+	    intended for a crypto maintainer.</p>
+          <p>
+	    The first element on call stack (the <c>S</c> in <c>try
+	    ... catch error:E:S .... end</c>) gives more information
+	    like the actual argument list in the call of crypto and
+	    the argument number (if possible) in the call to the NIF
+	    inside crypto.</p>
+          <p>
+	    The functions in crypto affected by this change are:</p>
+          <p>
+	    sign/4, sign/5, verify/5, verify/6,</p>
+          <p>

+	    public_encrypt/4, private_decrypt/4, private_encrypt/4,
+	    public_decrypt/4</p>
+          <p>
+	    This schema was introduced earlier in:</p>
+          <p>
+	    crypto_init/3, crypto_init/4, crypto_update/2,
+	    crypto_final/1, crypto_get_data/1,</p>

+	    When one knows that the value being tested must be a
+	    binary, <c>byte_size/1</c> should be preferred. However,
+	    <c>byte_size/1</c> also accepts a bitstring (rounding up
+	    size to a whole number of bytes), so one must make sure
+	    that the call to <c>byte_size/</c> is preceded by a call
+	    to <c>is_binary/1</c> to ensure that bitstrings are
+	    rejected. Note that the compiler removes redundant calls
+	    to <c>is_binary/1</c>, so if one is not sure whether
+	    previous code had made sure that the argument is a
+	    binary, it does not harm to add an <c>is_binary/1</c>

+	    <p>Two bugs have been fixed in Dialyzer's checking of
+	    behaviors:</p>
+	    <p>When a <em>mandatory</em> callback function is present
+	    but not exported, Dialyzer would not complain about a
+	    missing callback.</p>
+	    <p>When an <em>optional</em> callback function was not
+	    exported and had incompatible arguments and/or the return
+	    values were incompatible, Dialyzer would complain. This
+	    has been changed to suppress the warning, because the
+	    function might not be intended to be a callback function,
+	    for instance if a release added a new optional callback
+	    function (such as <c>format_status/1</c> for the
+	    gen_server behaviour added in OTP 25).</p>

-%%	Analyzes a module or an expression represented by `Tree'.
-%%
-%%	The returned `OutList' is a list of sets of labels of
-%%	fun-expressions which correspond to the possible closures in the
-%%	value list produced by `Tree' (viewed as an expression; the
-%%	"value" of a module contains its exported functions). The atom
-%%	`none' denotes missing or conflicting information.
-%%
-%%	The atom `external' in any label set denotes any possible
-%%	function outside `Tree', including those in `Escapes'. The atom
-%%	`top' denotes the top-level expression `Tree'.
-%%
-%%	`Outputs' is a mapping from the labels of fun-expressions in
-%%	`Tree' to corresponding lists of sets of labels of
-%%	fun-expressions (or the atom `none'), representing the possible
-%%	closures in the value lists returned by the respective
-%%	functions.
-%%
-%%	`Dependencies' is a similar mapping from the labels of
-%%	fun-expressions and apply-expressions in `Tree' to sets of
-%%	labels of corresponding fun-expressions which may contain call
-%%	sites of the functions or be called from the call sites,
-%%	respectively. Any such label not defined in `Dependencies'
-%%	represents an unreachable function or a dead or faulty
-%%	application.
-%%
-%%	`Escapes' is the set of labels of fun-expressions in `Tree' such
-%%	that corresponding closures may be accessed from outside `Tree'.
-%%
-%%	`Parents' is a mapping from labels of fun-expressions in `Tree'
-%%	to the corresponding label of the nearest containing
-%%	fun-expression or top-level expression. This can be used to
-%%	extend the dependency graph, for certain analyses.
-%%
-%%	Note: `Tree' must be annotated with labels (as done by the
-%%	function `cerl_trees:label/1') in order to use this function.
-%%	The label annotation `{label, L}' (where L should be an integer)
-%%	must be the first element of the annotation list of each node in
-%%	the tree. Instances of variables bound in `Tree' which denote
-%%	the same variable must have the same label; apart from this,
-%%	labels should be unique. Constant literals do not need to be
-%%	labeled.

-
-%% Note: In order to keep our domain simple, we assume that all remote
-%% calls and primops return a single value, if any.
-
-%% We use the terms `closure', `label', `lambda' and `fun-expression'
-%% interchangeably. The exact meaning in each case can be grasped from
-%% the context.
-%%
-%% Rules:
-%%   1) The implicit top level lambda escapes.
-%%   2) A lambda returned by an escaped lambda also escapes.
-%%   3) An escaped lambda can be passed an external lambda as argument.
-%%   4) A lambda passed as argument to an external lambda also escapes.
-%%   5) An argument passed to an unknown operation escapes.
-%%   6) A call to an unknown operation can return an external lambda.
-%%
-%% Escaped lambdas become part of the set of external lambdas, but this
-%% does not need to be represented explicitly.
-
-%% We wrap the given syntax tree T in a fun-expression labeled `top',
-%% which is initially in the set of escaped labels. `top' will be
-%% visited at least once.
-%%
-%% We create a separate function labeled `external', defined as:
-%% "'external'/1 = fun (Escape) -> do apply 'external'/1(apply Escape())
-%% 'external'/1", which will represent any and all functions outside T,
-%% and which returns itself, and contains a recursive call; this models
-%% rules 2 and 4 above. It will be revisited if the set of escaped
-%% labels changes, or at least once. Its parameter `Escape' is a
-%% variable labeled `escape', which will hold the set of escaped labels.
-%% initially it contains `top' and `external'.

-%% Peephole optimizations
-%%
-%% This is only intended to be a light-weight cleanup optimizer,
-%% removing small things that may e.g. have been generated by other
-%% optimization passes or in the translation from higher-level code.
-%% It is not recursive in general - it only descends until it can do no
-%% more work in the current context.
-%%
-%% To expose hidden cases of final expressions (enabling last call
-%% optimization), we try to remove all trivial let-bindings (`let X = Y
-%% in X', `let X = Y in Y', `let X = Y in let ... in ...', `let X = let
-%% ... in ... in ...', etc.). We do not, however, try to recognize any
-%% other similar cases, even for simple `case'-expressions like `case E
-%% of X -> X end', or simultaneous multiple-value bindings.

+%%               Since June 2008 typer is maintained by Kostis Sagonas.
+%%               On 2022, Brujo Benavides, Pablo Costas, and Mackenzie

+	    the derived AVP data format Address whose first two
+	    octets specify an address family other than 1 (IP) or 2
+	    (IP6). Such values have never been decoded, and were
+	    treated as decode errors. They're now decoded to a
+	    2-tuple of the integer() address family and binary()
+	    remaining octets, with no family-specific decode. The
+	    2-tuple distinguishes the decode from the 4-tuple and
+	    8-tuple IP address decodes. 2-tuples are also now
+	    encoded.</p>
+          <p>
+	    Note that even currently unassigned address families are
+	    decoded: only the reserved values, 0 and 65535, are

-/* The Erlang release for VxWorks includes a simple mechanism for
-   "resource reclamation" at task exit - it allows replacement of the
-   functions that open/close "files" and malloc/free memory with versions
-   that keep track, to be able to "reclaim" file descriptors and memory
-   when a task exits (regardless of *how* it exits).
-
-   The interface to this mechanism is made available via this file,
-   with the following caveats:
-
-   - The interface may change (or perhaps even be removed, though that
-     isn't likely until VxWorks itself provides similar functionality)
-     in future releases - i.e. you must always use the version of this
-     file that comes with the Erlang release you are using.
-
-   - Disaster is guaranteed if you use the mechanism incorrectly (see
-     below for the correct way), e.g. allocate memory with the "tracking"
-     version of malloc() and free it with the "standard" version of free().
-
-   - The mechanism (of course) incurs some performance penalty - thus
-     for a simple program you may be better off with careful programming,
-     making sure that you do whatever close()/free()/etc calls that are
-     appropriate at all exit points (though if you need to guard against
-     taskDelete() etc, things get messy...).
-
-   To use the mechanism, simply program your application normally, i.e.
-   use open()/close()/malloc()/free() etc as usual, but #include this
-   file before any usage of the relevant functions. NOTE: To avoid the
-   "disaster" mentioned above, you *must* #include it in *all* (or none)
-   of the files that manipulate a particular file descriptor, allocated
-   memory area, etc.
-
-   Before any task that uses this utility is loaded (which includes the 
-   erlang emulator), the reclaim.o object file has to be loaded and
-   the function reclaim_init() has to be called. reclaim_init should be called
-   only _ONCE_ in a systems lifetime and has only a primitive guard
-   against multiple calls (i.e. a global variable is checked). Therefore
-   the initialization should occur either in the start script of the system
-   or (even better) in the usrInit() part of system initialization. The 
-   object file itself should be loaded only once, so linking it with the
-   kernel is a good idea, linking with each application is an extremely bad 
-   dito. Make really sure that it's loaded _before_ any application that 
-   uses it if You want to load it in the startup script.
-
-   If You dont want to have #define's for the posix/stdio names
-   of the file/memory operations (i.e. no #define malloc save_malloc etc),
-   #define RECLAIM_NO_ALIAS in Your source before reclaim.h is included.

+	    When one knows that the value being tested must be a
+	    binary, <c>byte_size/1</c> should be preferred. However,
+	    <c>byte_size/1</c> also accepts a bitstring (rounding up
+	    size to a whole number of bytes), so one must make sure
+	    that the call to <c>byte_size/</c> is preceded by a call
+	    to <c>is_binary/1</c> to ensure that bitstrings are
+	    rejected. Note that the compiler removes redundant calls
+	    to <c>is_binary/1</c>, so if one is not sure whether
+	    previous code had made sure that the argument is a
+	    binary, it does not harm to add an <c>is_binary/1</c>

+	    When one knows that the value being tested must be a
+	    binary, <c>byte_size/1</c> should be preferred. However,
+	    <c>byte_size/1</c> also accepts a bitstring (rounding up
+	    size to a whole number of bytes), so one must make sure
+	    that the call to <c>byte_size/</c> is preceded by a call
+	    to <c>is_binary/1</c> to ensure that bitstrings are
+	    rejected. Note that the compiler removes redundant calls
+	    to <c>is_binary/1</c>, so if one is not sure whether
+	    previous code had made sure that the argument is a
+	    binary, it does not harm to add an <c>is_binary/1</c>
+	    test immediately before the call to <c>byte_size/1</c>.</p>

+	    Adds more type information to the <c>inets</c> app, thus
+	    improving the errors that static analysis tools can
+	    detect.</p>
+          <p>
+	    The addition of type information to records and the
+	    updates to function heads help static analysis tools to
+	    understand that some values in the records cannot be
+	    <c>'undefined'</c>, thus making static tools to type
+	    check correctly more modules in the <c>inets</c> app</p>

+	    Replace size/1 with either tuple_size/1 or byte_size/1</p>
+          <p>
+	    The <c>size/1</c> BIF is not optimized by the JIT, and
+	    its use can result in worse types for Dialyzer.</p>
+          <p>
+	    When one knows that the value being tested must be a
+	    tuple, <c>tuple_size/1</c> should always be preferred.</p>
+          <p>
+	    When one knows that the value being tested must be a
+	    binary, <c>byte_size/1</c> should be preferred. However,
+	    <c>byte_size/1</c> also accepts a bitstring (rounding up
+	    size to a whole number of bytes), so one must make sure
+	    that the call to <c>byte_size/</c> is preceded by a call
+	    to <c>is_binary/1</c> to ensure that bitstrings are
+	    rejected. Note that the compiler removes redundant calls
+	    to <c>is_binary/1</c>, so if one is not sure whether
+	    previous code had made sure that the argument is a
+	    binary, it does not harm to add an <c>is_binary/1</c>
+	    test immediately before the call to <c>byte_size/1</c>.</p>

-%% This is from chapter 3, Syntax Components, of RFC 3986: 
-%% 
-%% The generic URI syntax consists of a hierarchical sequence of
-%% components referred to as the scheme, authority, path, query, and
-%% fragment.
-%% 
-%%    URI         = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
-%% 
-%%    hier-part   = "//" authority path-abempty
-%%                   / path-absolute
-%%                   / path-rootless
-%%                   / path-empty
-%% 
-%%    The scheme and path components are required, though the path may be
-%%    empty (no characters).  When authority is present, the path must
-%%    either be empty or begin with a slash ("/") character.  When
-%%    authority is not present, the path cannot begin with two slash
-%%    characters ("//").  These restrictions result in five different ABNF
-%%    rules for a path (Section 3.3), only one of which will match any
-%%    given URI reference.
-%% 
-%%    The following are two example URIs and their component parts:
-%% 
-%%          foo://example.com:8042/over/there?name=ferret#nose
-%%          \_/   \______________/\_________/ \_________/ \__/
-%%           |           |            |            |        |

-%%          / \ /                        \
-%%          urn:example:animal:ferret:nose
-%% 
-%%    scheme      = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )

+	    <p> As of OTP 25, <c>global</c> will by default prevent
+	    overlapping partitions due to network issues by actively
+	    disconnecting from nodes that reports that they have lost
+	    connections to other nodes. This will cause fully
+	    connected partitions to form instead of leaving the
+	    network in a state with overlapping partitions. </p> <p>
+	    Prevention of overlapping partitions can be disabled
+	    using the <seeapp
+	    marker="kernel_app#prevent_overlapping_partitions"><c>prevent_overlapping_partitions</c></seeapp>
+	    <c>kernel(6)</c> parameter, making <c>global</c> behave
+	    like it used to do. This is, however, problematic for all
+	    applications expecting a fully connected network to be
+	    provided, such as for example <c>mnesia</c>, but also for
+	    <c>global</c> itself. A network of overlapping partitions
+	    might cause the internal state of <c>global</c> to become
+	    inconsistent. Such an inconsistency can remain even after
+	    such partitions have been brought together to form a
+	    fully connected network again. The effect on other
+	    applications that expects that a fully connected network
+	    is maintained may vary, but they might misbehave in very
+	    subtle hard to detect ways during such a partitioning.
+	    Since you might get hard to detect issues without this
+	    fix, you are <i>strongly</i> advised <i>not</i> to
+	    disable this fix. Also note that this fix <i>has</i> to
+	    be enabled on <i>all</i> nodes in the network in order to
+	    work properly. </p>

+	    <p> By default <c>global</c> does <i>not</i> take any
+	    actions to restore a fully connected network when
+	    connections are lost due to network issues. This is
+	    problematic for all applications expecting a fully
+	    connected network to be provided, such as for example
+	    <c>mnesia</c>, but also for <c>global</c> itself. A
+	    network of overlapping partitions might cause the
+	    internal state of <c>global</c> to become inconsistent.
+	    Such an inconsistency can remain even after such
+	    partitions have been brought together to form a fully
+	    connected network again. The effect on other applications
+	    that expects that a fully connected network is maintained
+	    may vary, but they might misbehave in very subtle hard to
+	    detect ways during such a partitioning. </p> <p> In order
+	    to prevent such issues, we have introduced a <i>prevent
+	    overlapping partitions</i> fix which can be enabled using
+	    the <seeapp
+	    marker="kernel:kernel_app#prevent_overlapping_partitions"><c>prevent_overlapping_partitions</c></seeapp>
+	    <c>kernel(6)</c> parameter. When this fix has been
+	    enabled, <c>global</c> will actively disconnect from
+	    nodes that reports that they have lost connections to
+	    other nodes. This will cause fully connected partitions
+	    to form instead of leaving the network in a state with
+	    overlapping partitions. Note that this fix <i>has</i> to
+	    be enabled on <i>all</i> nodes in the network in order to
+	    work properly. Since this quite substantially changes the
+	    behavior, this fix is currently disabled by default.
+	    Since you might get hard to detect issues without this
+	    fix you are, however, <i>strongly</i> advised to enable
+	    this fix in order to avoid issues such as the ones
+	    described above. As of OTP 25 this fix will become
+	    enabled by default. </p>

+	    <p> By default <c>global</c> does <i>not</i> take any
+	    actions to restore a fully connected network when
+	    connections are lost due to network issues. This is
+	    problematic for all applications expecting a fully
+	    connected network to be provided, such as for example
+	    <c>mnesia</c>, but also for <c>global</c> itself. A
+	    network of overlapping partitions might cause the
+	    internal state of <c>global</c> to become inconsistent.
+	    Such an inconsistency can remain even after such
+	    partitions have been brought together to form a fully
+	    connected network again. The effect on other applications
+	    that expects that a fully connected network is maintained
+	    may vary, but they might misbehave in very subtle hard to
+	    detect ways during such a partitioning. </p> <p> In order
+	    to prevent such issues, we have introduced a <i>prevent
+	    overlapping partitions</i> fix which can be enabled using
+	    the <c>prevent_overlapping_partitions</c>
+	    <c>kernel(6)</c> parameter. When this fix has been
+	    enabled, <c>global</c> will actively disconnect from
+	    nodes that reports that they have lost connections to
+	    other nodes. This will cause fully connected partitions
+	    to form instead of leaving the network in a state with
+	    overlapping partitions. Note that this fix <i>has</i> to
+	    be enabled on <i>all</i> nodes in the network in order to
+	    work properly. Since this quite substantially changes the
+	    behavior, this fix is currently disabled by default.
+	    Since you might get hard to detect issues without this
+	    fix you are, however, <i>strongly</i> advised to enable
+	    this fix in order to avoid issues such as the ones
+	    described above. As of OTP 25 this fix will become
+	    enabled by default. </p>

+	    <c>byte_size/1</c> also accepts a bitstring (rounding up
+	    size to a whole number of bytes), so one must make sure
+	    that the call to <c>byte_size/</c> is preceded by a call
+	    to <c>is_binary/1</c> to ensure that bitstrings are
+	    rejected. Note that the compiler removes redundant calls
+	    to <c>is_binary/1</c>, so if one is not sure whether

By using <c>spread_tag/1</c> and <c>restore_tag/1</c>, one can enable or disable spreading of user tags to other processes and then restore the previous state of the user tag. The TagData returned from this call contains all previous information so the state (including any previously spread user tags) will be completely restored by a later call to <c>restore_tag/1</c>.</p> 
-	<p>The <seeerl marker="kernel:file">file</seeerl> module already spread's tags, so there is noo need to manually call these function to get user tags spread to the efile driver through that module.</p>

-%% Purpose: We must calculate the length of an empty Pdu.  This

-%%          for each get-bulk-request. This size is 
-%%          dependent on the varbinds. It is calculated
-%%          as EmptySize + 8.  8 comes from the fact that the
-%%          maximum pdu size needs 31 bits which needs 5 * 7 bits to be
-%%          expressed. One 7bit octet is already present in the
-%%          empty pdu, leaving 4 more 7bit octets. The length is
-%%          repeated twice, once for the varbinds, and once for the

+%%          It is calculated as EmptySize + 8.  8 comes from the

-%%% The test case structure is as follows:
-%%%
-%%% init_all - starts mnesia, 
-%%%      
-%%%    init_v1 - starts agent
-%%%       simple
-%%%       big  - e.g. starts/stops subagent, load/unloads mibs
-%%%       init_mul
-%%%          mul_get
-%%%          mul_set
-%%%          <etc>
-%%%       finish_mul
-%%%       <etc>
-%%%    finish_v1
-%%%
-%%%    init_v2 - starts agent
-%%%    finish_v2
-%%%      
-%%%    init_bilingual - starts agent
-%%%    finish_bilingual
-%%%      
-%%% finish_all
-%%%
-%%% There is still one problem with these testsuites.  If one test
-%%% fails, it may not be possible to run some other cases, as it
-%%% may have e.g. created some row or loaded some table, that it
-%%% didn't undo (since it failed).

-%%% The test case structure is as follows:
-%%%
-%%% init_all - starts mnesia, 
-%%%      
-%%%    init_v1 - starts agent
-%%%       simple
-%%%       big  - e.g. starts/stops subagent, load/unloads mibs
-%%%       init_mul
-%%%          mul_get
-%%%          mul_set
-%%%          <etc>
-%%%       finish_mul
-%%%       <etc>
-%%%    finish_v1
-%%%
-%%%    init_v2 - starts agent
-%%%    finish_v2
-%%%      
-%%%    init_bilingual - starts agent
-%%%    finish_bilingual
-%%%      
-%%% finish_all
-%%%
-%%% There is still one problem with these testsuites.  If one test
-%%% fails, it may not be possible to run some other cases, as it
-%%% may have e.g. created some row or loaded some table, that it
-%%% didn't undo (since it failed).

-%%%-----------------------------------------------------------------
-%%% The test case structure is as follows:
-%%%
-%%% init_all - starts mnesia, 
-%%%      
-%%%    init_v1 - starts agent
-%%%       simple
-%%%       big  - e.g. starts/stops subagent, load/unloads mibs
-%%%       init_mul
-%%%          mul_get
-%%%          mul_set
-%%%          <etc>
-%%%       finish_mul
-%%%       <etc>
-%%%    finish_v1
-%%%
-%%%    init_v2 - starts agent
-%%%    finish_v2
-%%%      
-%%%    init_bilingual - starts agent
-%%%    finish_bilingual
-%%%      
-%%% finish_all
-%%%
-%%% There is still one problem with these testsuites.  If one test
-%%% fails, it may not be possible to run some other cases, as it
-%%% may have e.g. created some row or loaded some table, that it
-%%% didn't undo (since it failed).

-%%% The test case structure is as follows:
-%%%
-%%% init_all - starts mnesia, 
-%%%      
-%%%    init_v1 - starts agent
-%%%       simple
-%%%       big  - e.g. starts/stops subagent, load/unloads mibs
-%%%       init_mul
-%%%          mul_get
-%%%          mul_set
-%%%          <etc>
-%%%       finish_mul
-%%%       <etc>
-%%%    finish_v1
-%%%
-%%%    init_v2 - starts agent
-%%%    finish_v2
-%%%      
-%%%    init_bilingual - starts agent
-%%%    finish_bilingual
-%%%      
-%%% finish_all
-%%%
-%%% There is still one problem with these testsuites.  If one test
-%%% fails, it may not be possible to run some other cases, as it
-%%% may have e.g. created some row or loaded some table, that it
-%%% didn't undo (since it failed).

+	    When one knows that the value being tested must be a

+	    <c>byte_size/1</c> also accepts a bitstring (rounding up
+	    size to a whole number of bytes), so one must make sure
+	    that the call to <c>byte_size/</c> is preceded by a call
+	    to <c>is_binary/1</c> to ensure that bitstrings are
+	    rejected. Note that the compiler removes redundant calls
+	    to <c>is_binary/1</c>, so if one is not sure whether
+	    previous code had made sure that the argument is a
+	    binary, it does not harm to add an <c>is_binary/1</c>

+	    A vulnerability has been discovered and corrected. It is
+	    registered as CVE-2022-37026 "Client Authentication
+	    Bypass". Corrections have been released on the supported
+	    tracks with patches 23.3.4.15, 24.3.4.2, and 25.0.2. The
+	    vulnerability might also exist in older OTP versions. We
+	    recommend that impacted users upgrade to one of these
+	    versions or later on the respective tracks. OTP 25.1
+	    would be an even better choice. Impacted are those who
+	    are running an ssl/tls/dtls server using the ssl
+	    application either directly or indirectly via other
+	    applications. For example via inets (httpd), cowboy, etc.
+	    Note that the vulnerability only affects servers that
+	    request client certification, that is sets the option
+	    {verify, verify_peer}.</p>

+	    In the initial release of Erlang/OTP 25, the expression
+	    bound to the <c>_</c> pseudo-field in a record
+	    initialization would always be evaluated once, even if
+	    all other fields in the record were explicitly
+	    initialized. That would break the use case of binding the
+	    expression <c>error(...)</c> to <c>_</c> in order to get
+	    an exception if not all fields were initialized.</p>
+          <p>
+	    The behavior of binding to <c>_</c> has been reverted to
+	    the pre-OTP 25 behavior, that is, to not evaluate the
+	    expression if all fields have been bound to explicit
+	    values.</p>

+	    If a default record field initialization (<c>_ =

+	    explicitly initialized, <c>Expr</c> would not be
+	    evaluated. That would not be a problem, except when
+	    <c>Expr</c> would bind a variable subsequently used, in
+	    which case the compiler would crash.</p>
+          <p>
+	    As an example, if record <c>#r{}</c> is defined to have
+	    only one field <c>a</c>, the following code would crash
+	    the compiler:</p>
+          <p>
+	    <c>#r{a=[],_=V=42}, V</c></p>
+          <p>
+	    To fix that problem, the compiler will make sure that
+	    <c>Expr</c> is always evaluated at least once. The
+	    compiler will now rewrite the example to essentially:</p>
+          <p>

+  <modulesummary>Start and control linked Erlang nodes.
+  </modulesummary>
+  <description>
+    <p>
+      This module provides functions for starting linked Erlang nodes.
+      The node spawning new nodes is called <em>origin</em>, and newly started
+      nodes are <em>peer</em> nodes, or peers. A peer node automatically
+      terminates when it loses the <em>control connection</em> to the origin. This
+      connection could be an Erlang distribution connection, or an alternative -
+      TCP or standard I/O. The alternative connection provides a way to execute
+      remote procedure calls even when Erlang Distribution is not available,
+      allowing to test the distribution itself.
+    </p>
+
+    <p>
+      Peer node terminal input/output is relayed through the origin.
+      If a standard I/O alternative connection is requested, console output
+      also goes via the origin, allowing debugging of node startup and boot
+      script execution (see <seecom marker="erts:erl#init_debug">
+      <c>-init_debug</c></seecom>). File I/O is not redirected, contrary to
+      <seeerl marker="slave"><c>slave(3)</c></seeerl> behaviour.
+    </p>
+
+    <p>
+      The peer node can start on the same or a different host (via <c>ssh</c>)
+      or in a separate container (for example Docker).
+      When the peer starts on the same host as the origin, it inherits
+      the current directory and environment variables from the origin.
+    </p>
+
+    <note>
+      <p>
+      This module is designed to facilitate multi-node testing with Common Test.
+      Use the <c>?CT_PEER()</c> macro to start a linked peer node according to
+      Common Test conventions: crash dumps written to specific location, node
+      name prefixed with module name, calling function, and origin OS process
+      ID). Use <seemfa marker="#random_name/1"><c>random_name/1</c></seemfa> to
+      create sufficiently unique node names if you need more control.
+      </p>
+      <p>
+      A peer node started without alternative connection behaves similarly
+      to <seeerl marker="slave"><c>slave(3)</c></seeerl>. When an alternative
+      connection is requested, the behaviour is similar to
+      <c>test_server:start_node(Name, peer, Args).</c>
+    </p> </note>

+    <title>Example</title>
+    <p>
+      The following example implements a test suite starting extra Erlang nodes.
+      It employs a number of techniques to speed up testing and reliably shut
+      down peer nodes:
+    </p>
+    <list>
+      <item>peers start linked to test runner process. If the test case fails,
+      the peer node is stopped automatically, leaving no rogue nodes running in
+      the background</item>
+      <item>arguments used to start the peer are saved in the control process
+      state for manual analysis. If the test case fails, the CRASH REPORT contains
+      these arguments</item>
+      <item>multiple test cases can run concurrently speeding up overall testing
+      process, peer node names are unique even when there are multiple instances
+      of the same test suite running in parallel</item>
+    </list>
+    <code type="erl">
+      -module(my_SUITE).
+      -behaviour(ct_suite).
+      -export([all/0, groups/0]).
+      -export([basic/1, args/1, named/1, restart_node/1, multi_node/1]).
+
+      -include_lib("common_test/include/ct.hrl").
+
+      groups() ->
+          [{quick, [parallel],
+              [basic, args, named, restart_node, multi_node]}].
+
+      all() ->
+          [{group, quick}].
+
+      basic(Config) when is_list(Config) ->
+          {ok, Peer, _Node} = ?CT_PEER(),
+          peer:stop(Peer).
+
+      args(Config) when is_list(Config) ->
+          %% specify additional arguments to the new node
+          {ok, Peer, _Node} = ?CT_PEER(["-emu_flavor", "smp"]),
+          peer:stop(Peer).
+
+      named(Config) when is_list(Config) ->
+          %% pass test case name down to function starting nodes
+          Peer = start_node_impl(named_test),
+          peer:stop(Peer).
+
+      start_node_impl(ActualTestCase) ->
+          {ok, Peer, Node} = ?CT_PEER(#{name => ?CT_PEER_NAME(ActualTestCase)}),
+          %% extra setup needed for multiple test cases
+          ok = rpc:call(Node, application, set_env, [kernel, key, value]),
+          Peer.
+
+      restart_node(Config) when is_list(Config) ->
+          Name = ?CT_PEER_NAME(),
+          {ok, Peer, Node} = ?CT_PEER(#{name => Name}),
+          peer:stop(Peer),
+          %% restart the node with the same name as before
+          {ok, Peer2, Node} = ?CT_PEER(#{name => Name, args => ["+fnl"]}),
+          peer:stop(Peer2).
+    </code>
+
+    <p>
+      The next example demonstrates how to start multiple nodes concurrently:
+    </p>
+    <code type="erl">
+      multi_node(Config) when is_list(Config) ->
+          Peers = [?CT_PEER(#{wait_boot => {self(), tag}})
+              || _ &lt;- lists:seq(1, 4)],
+          %% wait for all nodes to complete boot process, get their names:
+          _Nodes = [receive {tag, {started, Node, Peer}} -> Node end
+              || {ok, Peer} &lt;- Peers],
+          [peer:stop(Peer) || {ok, Peer} &lt;- Peers].
+    </code>
+
+    <p>
+      Start a peer on a different host. Requires <c>ssh</c> key-based
+      authentication set up, allowing "another_host" connection without password
+      prompt.
+    </p>
+    <code type="erl">
+      Ssh = os:find_executable("ssh"),
+      peer:start_link(#{exec => {Ssh, ["another_host", "erl"]},
+          connection => standard_io}),
+    </code>
+
+    <p>
+      The following Common Test case demonstrates Docker integration, starting two
+      containers with hostnames "one" and "two". In this example Erlang nodes
+      running inside containers form an Erlang cluster.
+    </p>
+    <code type="erl">

+        This section contains special purpose algorithms
+        that does not use the
+        <seeerl marker="#plug_in_api">plug-in framework API</seeerl>,
+        for example for speed reasons.
+      </p>
+      <p>
+        Since these algorithms lack the plug-in framework support,
+        generating numbers in a range other than the
+        generator's own generated range may become a problem.
+      </p>
+      <p>
+        There are at least 3 ways to do this, assuming that
+        the range is less than the generator's range:

+          </p>
+          <list type="bulleted">
+            <item>Generate a number <c>X</c>.</item>
+            <item>

+            </item>
+          </list>
+          <p>
+            This method uses <c>rem</c>, that is, the remainder of
+            an integer division, which is a slow operation.
+          </p>
+          <p>
+            Low bits from the generator propagate straight through
+            to the generated value, so if the generator has got
+            weaknesses in the low bits this method propagates
+            them too.
+          </p>
+          <p>
+            If <c>Range</c> is not a divisor of the generator range,
+            the generated numbers have a bias.
+            Example:
+          </p>
+          <p>
+            Say the generator generates a byte, that is,
+            the generator range is 0..255,
+            and the desired range is 0..99 (<c>Range=100</c>).
+            Then there are 3 generator outputs that produce the value 0,
+            that is; 0, 100 and 200.  But there are only
+            2 generator outputs that produce the value 99,
+            which are; 99 and 199.  So the probability for
+            a value <c>V</c> in 0..55 is 3/2 times
+            the probability for the other values 56..99.
+          </p>
+          <p>
+            If <c>Range</c> is much smaller than the generator range,
+            then this bias gets hard to detect.  The rule of thumb is
+            that if <c>Range</c> is smaller than the square root
+            of the generator range, the bias is small enough.
+            Example:
+          </p>
+          <p>
+            A byte generator when <c>Range=20</c>.
+            There are 12 (<c>256&nbsp;div&nbsp;20</c>)
+            possibilities to generate the highest numbers
+            and one more to generate a number
+            <c>V</c>&nbsp;&lt;&nbsp;16 (<c>256&nbsp;rem&nbsp;20</c>).
+            So the probability is 13/12 for a low number
+            versus a high.  To detect that difference
+            with some confidence you would need to generate
+            a lot more numbers than the generator range,
+            256 in this small example.

+            In theory it is not certain that this method

+            that the probability of rejection is low.
+            Then the probability for yet another iteration
+            decreases exponentially so the expected mean
+            number of iterations will often be between 1 and 2.
+            Also, since the base generator is a full length generator,
+            a value that will break the loop must eventually

+        Chese methods can be combined, such as using the <em>Modulo</em>
+        method and only if the generator value would create bias
+        use <em>Rejection</em>.  Or using <em>Shift or mask</em>

+        </p>
+        <p>
+          This generator uses the multiplier 2^32 and the modulus
+          16#7fa6502&nbsp;*&nbsp;2^32&nbsp;-&nbsp;1,
+          which have been selected,

+          to avoid bignum operations
+          and still get good statistical quality.
+          It can be written as:<br/>

+        <p>
+          Because the generator uses a multiplier that is
+          a power of 2 it gets statistical flaws for collision tests
+          and birthday spacings tests in 2 and 3 dimensions,
+          and even these caveats apply only to the MWC "digit",
+          that is the low 32 bits (due to the multiplier) of
+          the generator state.
+        </p>
+        <p>
+          The quality of the output value improves much by using

+%% Controller for additional Erlang node running on the same host,
+%%  or in a different container/host (e.g. Docker).
+%%
+%% == Terms ==
+%% Origin node - Erlang VM instance that spawns additional nodes.
+%% Peer node - a node spawned by the origin.
+%% Control process - a process running on origin node, if it terminates,
+%%  peer node terminates too.
+%% Control connection - a connection between origin and peer, can be
+%%  ether Erlang Distribution connection, or alternative one.
+%%
+%% I/O is forwarded from peer node to origin via control connection.
+%%
+%% When standard_io is used as alternative connection, peer node
+%%  uses standard out to multiplex console output and control sequences.
+%% Characters in range of 192-255 are reserved for control sequences,
+%%  see encode_port_data for details. If peer node attempts to print
+%%  characters in this range, an controlling process on the origin
+%%  node may terminate with an error (because CRC check will fail).
+%%
+%% Alternative connection via TCP does not have that limitation, but
+%%  it also does not redirect console I/O from the peer node.

+%% An MWC generator has, due to the power of two multiplier

+%% and settled for a single Xorshift to get B good bits,
+%% and a double Xorshift to get all bits good enough.

+%% Double Xorshift: 4, 27

+  another process or a port identified by PidOrPort. We will from
+  here on call the identified process or port linkee. If the linkee
+  is a port, it must reside on the same node as the caller.
 
-  If PidOrPort does not exist and checking it is cheap, a noproc
-  error is raised. Currently, checking is cheap if the PidOrPort
-  is local and the caller does not trap exits (see process_flag/2 
-  ).
+  If one of the participants of a link terminates, it will send an
+  exit signal to the other participant. The exit signal will
+  contain the exit reason of the terminated participant. Other
+  cases when exit signals are triggered due to a link are when no
+  linkee exist (noproc exit reason) and when the connection
+  between linked processes on different nodes is lost or cannot be
+  established (noconnection exit reason).
 
-  Apart from any exit signals from the linked process itself, two
-  special exit signals may be sent to the calling process:
+  An existing link can be removed by calling unlink/1. For more
+  information on links and exit signals due to links, see the 
+  Processes chapter in the Erlang Reference Manual:
 
-   • noproc is sent immediately if PidOrPort does not exist at
-     the time of linking (if the caller is trapping exits or 
-     PidOrPort is remote).

-   • noconnection if PidOrPort is remote and a connection
-     between the nodes could not be established or was severed.
+   • Sending Exit Signals
 
-  See Processes ➜ Links in the Erlang Reference Manual for more
-  details.
+   • Receiving Exit Signals
+
+  For historical reasons, link/1 has a strange semi-synchronous
+  behavior when it is "cheap" to check if the linkee exists or not,
+  and the caller does not trap exits. If the above is true and the
+  linkee does not exist, link/1 will raise a noproc error 
+  exception. The expected behavior would instead have been that 
+  link/1 returned true, and the caller later was sent an exit
+  signal with noproc exit reason, but this is unfortunately not
+  the case. The noproc exception is not to be confused with an 
+  exit signal with exit reason noproc. Currently it is "cheap" to
+  check if the linkee exists when it is supposed to reside on the
+  same node as the calling process.
+
+  The link setup and activation is performed asynchronously. If the
+  link already exists, or if the caller attempts to create a link to
+  itself, nothing is done. A detailed description of the link
+  protocol can be found in the Distribution Protocol chapter of
+  the ERTS User's Guide.

+	    used to <c>erl</c> for enabling/disabling features
+	    allowed at runtime. The new <c>maybe</c> expression

-# Configuration subroutine to validate and canonicalize a configuration type.
-# Supply the specified configuration type as an argument.
-# If it is invalid, we print an error message on stderr and exit with code 1.
-# Otherwise, we print the canonical config type on stdout and succeed.

-
-# This file is supposed to be the same for all GNU packages
-# and recognize all the CPU types, system types and aliases

-# Each package is responsible for reporting which valid configurations

-# a failure to support a valid configuration from a meaningless
-# configuration.
-
-# The goal of this file is to map all the various variations of a given
-# machine specification into a single specification in the form:
-#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
-# or in some cases, the newer four-part form:
-#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
-# It is wrong to echo any other type of specification.

+    </note>
+
+    <code type="erl"><![CDATA[
+maybe
+    Expr1,
+    ...,
+    ExprN
+end]]></code>
+
+    <p>The expressions in a <c>maybe</c> block are evaluated sequentially. If all
+    expressions are evaluated successfully, the return value of the <c>maybe</c>
+    block is <c>ExprN</c>. However, execution can be short-circuited by a
+    conditional match expression:</p>
+
+    <code type="erl"><![CDATA[
+Expr1 ?= Expr2]]></code>
+
+    <p><c>?=</c> is called the conditional match operator. It is only
+    allowed to be used at the top-level of a <c>maybe</c> block. It
+    matches the pattern <c>Expr1</c> against <c>Expr2</c>. If the
+    matching succeeds, any unbound variable in the pattern becomes
+    bound. If the expression is the last expression in the
+    <c>maybe</c> block, it also returns the value of <c>Expr2</c>. If the
+    matching is unsuccessful, the rest of the expressions in the <c>maybe</c>
+    block are skipped and the return value of the <c>maybe</c>
+    block is <c>Expr2</c>.</p>
+
+    <p>None of the variables bound in a <c>maybe</c> block must be
+    used in the code that follows the block.</p>
+
+    <p>Here is an example:</p>
+
+    <code type="erl"><![CDATA[
+maybe
+    {ok, A} ?= a(),
+    true = A >= 0,
+    {ok, B} ?= b(),
+    A + B
+end]]></code>
+
+    <p>Let us first assume that <c>a()</c> returns <c>{ok,42}</c> and
+    <c>b()</c> returns <c>{ok,58}</c>. With those return values, all
+    of the match operators will succeed, and the return value of the
+    <c>maybe</c> block is <c>A + B</c>, which is equal to <c>42 +
+    58 = 100</c>.</p>
+
+    <p>Now let us assume that <c>a()</c> returns <c>error</c>. The
+    conditional match operator in <c>{ok, A} ?= a()</c> fails to
+    match, and the return value of the <c>maybe</c> block is the
+    value of the expression that failed to match, namely <c>error</c>.
+    Similarly, if <c>b()</c> returns <c>wrong</c>, the return value of
+    the <c>maybe</c> block is <c>wrong</c>.</p>
+
+    <p>Finally, let us assume that <c>a()</c> returns
+    <c>-1</c>. Because <c>true = A >= 0</c> uses the match operator
+    `=`, a <c>{badmatch,false}</c> run-time error occurs when the
+    expression fails to match the pattern.</p>
+
+    <p>The example can be written in a less succient way using nested
+    case expressions:</p>
+
+    <code type="erl"><![CDATA[
+case a() of
+    {ok, A} ->
+        true = A >= 0,
+        case b() of
+            {ok, B} ->
+                A + B;
+            Other1 ->
+                Other1
+        end;
+    Other2 ->
+        Other2
+end]]></code>
+
+    <p>The <c>maybe</c> block can be augmented with <c>else</c> clauses:</p>
+
+    <code type="erl"><![CDATA[
+maybe
+    Expr1,
+    ...,
+    ExprN
+else
+    Pattern1 [when GuardSeq1] ->
+        Body1;
+    ...;
+    PatternN [when GuardSeqN] ->
+        BodyN
+end]]></code>
+
+    <p>If a conditional match operator fails, the failed expression is
+    matched against the patterns in all clauses between the
+    <c>else</c> and <c>end</c> keywords. If a match succeeds and the
+    optional guard sequence <c>GuardSeq</c> is true, the corresponding
+    <c>Body</c> is evaluated. The value returned from the body is the
+    return value of the <c>maybe</c> block.</p>
+
+    <p>If there is no matching pattern with a true guard sequence,
+    an <c>else_clause</c> run-time error occurs.</p>
+
+    <p>None of the variables bound in a <c>maybe</c> block must be used in
+    the <c>else</c> clauses. None of the variables bound in the <c>else</c> clauses
+    must be used in the code that follows the <c>maybe</c> block.</p>
+
+    <p>Here is the previous example augmented with a <c>else</c> clauses:</p>
+
+    <code type="erl"><![CDATA[
+maybe
+    {ok, A} ?= a(),
+    true = A >= 0,
+    {ok, B} ?= b(),
+    A + B
+else
+    error -> error;
+    wrong -> error
+end]]></code>
+
+    <p>The <c>else</c> clauses translate the failing value from
+    the conditional match operators to the value <c>error</c>. If the
+    failing value is not one of the recognized values, a
+    <c>else_clause</c> run-time error occurs.</p>

+    Introduced in OTP 25, Erlang has the concept of selectable features.
+    A feature can change, add or remove behaviour of the language and/or
+    runtime system.  Examples can include

+  <p>
+    A feature will start out with a status of experimental part of OTP,
+    making it possible to try out for users and give feedback.  The
+    possibility to try out features is enabled by options to the
+    compiler, directives in a module and options to the runtime system.
+    Even when a feature is not experimental it will still be possible to
+    enable or disable it.  This makes it possible to adapt a code base
+    at a suitable pace instead of being forced when changing to a new
+    release.
+  </p>
+  <p>
+    The status of a feature will eventually end up as being either a
+    permanent part of OTP or rejected, being removed and no longer
+    selectable.
+  </p>
+
+  <section>

+    <p>A feature is in one of four possible states:</p>
+    <taglist>
+      <tag>Experimental</tag>
+      <item>The initial state, is meant for trying out and collecting
+      feedback.  The feature can be enabled but is disabled by

+      After leaving the experimental state, a feature can enter any of
+      the other three states, and if the next state is approved, the

+      can change state only in connection with a release.

+    <title>Enabling and Disabling Features</title>
+    <p>To use a feature that is in the experimental state, it has to
+    be enabled during compilation.  This can be done in a number of
+    different ways:
+    </p>
+    <taglist>
+      <tag>Options to <c>erlc</c></tag>
+      <item>Options <seecom
+      marker="erts:erlc#enable-feature"><c>-enable-feature</c></seecom>
+      and <seecom
+      marker="erts:erlc#disable-feature"><c>-disable-feature</c></seecom>
+      can be used to enable or disable individal features.</item>
+      <tag>Compiler options</tag>
+      <item>The compiler option <seeerl
+      marker="compiler:compile#feature-option"><c>{feature,
+      &lt;feature&gt;, enable|disable}</c></seeerl> can be used either
+      as a <c>+&lt;term&gt;</c> option to <c>erlc</c> or in the options
+      argument to functions in the <c>compile</c> module.</item>
+      <tag>The feature directive</tag>
+      <item>Inside a prefix of a module, one can use a <seeguide
+      marker="macros#feature-directive"><c>-feature(&lt;feature&gt;,
+      enable|disable)</c></seeguide> directive.  This is the preferred
+      method of enabling and disabling features.</item>
+    </taglist>
+    <p>
+      Note that to load a module compiled with features enabled, the
+      corresponding features must be enabled in the runtime.  This
+      is done using options <seecom
+      marker="erts:erl#enable-feature"><c>-enable-feature</c></seecom>
+      and <seecom
+      marker="erts:erl#disable-feature"><c>-disable-feature</c></seecom>
+      to <c>erl</c>.  This is to allow the possibility to prevent
+      the use of experimental features in, e.g., production.  This
+      will catch experimental features used in both own and third
+      party components.  An active choice to use experimental
+      features must be done.

+    <title>Opaque Type Aliases</title>
+    <p>The main use case for opacity in Erlang is to hide the implementation of a data type, enabling evolving the API while minimizing the risk of breaking consumers. The runtime does not check opacity. Dialyzer provides some opacity-checking, but the rest is up to convention.
+    </p>
+    <p>
+      This document explains what Erlang opacity is (and the trade-offs involved) via the example of OTP's
+      <c>sets:set()</c>
+      data type. This type
+      <em>was</em>
+      defined in `sets` module like this:
+    </p>
+    <code type="erl">-opaque set(Element) :: #set{segs :: segs(Element)}.</code>
+    <p>OTP 24  changed the definition to the following, in
+    <url href="https://github.com/erlang/otp/commit/e66941e8d7c47b973dff94c0308ea85a6be1958e">this commit</url>
+    </p>
+    <code type="erl">-opaque set(Element) :: #set{segs :: segs(Element)} | #{Element => ?VALUE}.</code>
+    <p>
+      And this change was safer and more backwards-compatible than if the type had been defined with
+      <c>-type</c>
+      instead of
+      <c>-opaque</c>
+      . Here's why: when a module defines an
+      <c>-opaque</c>
+      , the contract is that only the defining module should rely on the definition of the type: no other modules should rely on the definition.
+    </p>
+    <p>
+      This means that code that pattern-matched on
+      <c>set</c>
+      as a record/tuple technically broke the contract, and opted in to being potentially broken when the definition of
+      <c>set()</c>
+      changed. Before OTP 24, this code printed
+      <c>ok</c>
+      . In OTP 24 it may error:
+    </p>
+    <code type="erl">
+case sets:new() of
+    Set when is_tuple(Set) -&gt;
+        io:format(&quot;ok&quot;)
+end.
+    </code>
+    <p>
+      <strong>When working with an opaque defined in another module, here are some recommendations:</strong>
+    </p>
+
+    <list type="bulleted">
+      <item>
+        Don't examine the underlying type using pattern-matching, guards, or functions that reveal the type, such as
+        <c>tuple_size/1</c>
+        .
+      </item>
+      <item>
+        Instead, use functions provided by the module for working with the type. For example,
+        <c>sets</c>
+        module provides
+        <c>sets:new/0</c>
+        ,
+        <c>sets:add/2</c>
+        ,
+        <c>sets:is_element/2</c>
+        , etc.
+      </item>
+      <item>
+        <c>sets:set(a)</c>
+        is a subtype of
+        <c>sets:set(a | b)</c>
+        and not the other way around. Generally, you can rely on the property that
+        <c>the_opaque(T)</c>
+        is a subtype of
+        <c>the_opaque(U)</c>
+        when T is a subtype of U.
+      </item>
+    </list>
+    <p>
+      <strong>When defining your own opaques, here are some recommendations:</strong>
+    </p>
+    <list type="bulleted">
+      <item>
+        Since consumers are expected to not rely on the definition of the opaque type, you must provide functions for constructing and querying/deconstructing intances of your opaque type. For example, sets can be constructed with
+        <c>sets:new/0</c>, <c>sets:from_list/1</c>, <c>sets:add/2</c>, queried with <c>sets:is_element/2</c>, and deconstructed with<c>sets:to_list/1</c>.
+      </item>
+      <item>
+        Don't define an opaque with a type variable in parameter position. This breaks the normal and expected behavior that (for example)
+        <c>my_type(a)</c> is a subtype of <c>my_type(a | b)</c>
+      </item>
+      <item>
+        Add <seeguide marker="typespec">specs</seeguide> to exported functions that use the opaque type
+      </item>
+    </list>
+    <p>Note that opaques can be harder to work with for consumers, since the consumer is expected not to pattern-match and must instead use functions that the author of the opaque type provides to use instances of the type.</p>
+    <p>
+      Also, opacity in Erlang is skin-deep: the runtime does not enforce opacity-checking. So now that sets are implemented in terms of maps, an
+      <c>is_map</c>
+      check on a set
+      <em>will</em>
+      pass. The opacity rules are only enforced by convention and by additional tooling such as Dialyzer. And this enforcement is not total: For example, determined consumer of
+      <c>sets</c>
+      can still do things that reveal the structure of the set, such as by printing, serializing, or using a set as
+      <c>term()</c>
+      and then inspecting via functions like
+      <c>is_map</c>
+      or
+      <c>maps:get/2</c>
+      . And Dialyzer must make some
+      <url href="https://github.com/erlang/otp/issues/5118">approximations</url>
+      . Opacity checking has limitations, but is still a vital tool in scalable Erlang development.

+    <p>
+      NIFs and port driver code run inside the Erlang VM OS process (the
+      "Beam"). To maximize performance the code is called directly by the same
+      threads executing Erlang beam code and has full access to all the memory
+      of the OS process. A buggy NIF/driver can thus make severe damage by
+      corrupting memory.
+    </p>
+    <p>
+      In a best case scenario such memory corruption is detected immediately
+      causing the Beam to crash generating a core dump file which can be
+      analyzed to find the bug. However, it is very common for memory corruption
+      bugs to not be immediately detected when the faulty write happens, but
+      instead much later, for example when the calling Erlang process is garbage
+      collected. When that happens it can be very hard to find the root cause of
+      the memory corruption by analysing the core dump. All traces that could
+      have indicated which specific buggy NIF/driver that caused the corruption
+      may be long gone.

+	  APIs are seized in a consistent order that cannot result in deadlock
+	  bugs.
+	</p>
+      </item>
+    </list>
+    <p>
+      In fact, we recommend to use the debug emulator as default during
+      development of NIFs and drivers, regardless if you are troubleshooting
+      bugs or not. Some subtle bugs may not be detected by the normal emulator
+      and just happen to work anyway by chance. However, another version of the
+      emulator, or even different circumstances within the same emulator, may
+      cause the bug to later provoke all kinds of problems.
+    </p>
+    <p>
+      The main disadvantage of the <c>debug</c> emulator is its reduced
+      performance. The extra runtime checks and lack of compiler optimizations
+      may result in a slowdown with a factor of two or more depending on
+      load. The memory footprint should be about the same.
+    </p>
+    <p>
+      If the <c>debug</c> emulator is part of the Erlang/OTP installation, it can be
+      started with the <seecom marker="erts:erl#emu_type"><c>-emu_type</c></seecom>

+    <p>
+      The first variant starts Emacs and runs <c>gdb</c> within, while
+      the other <c>-rcore</c> runs <c>gdb</c> directly in the terminal. Apart
+      from starting <c>gdb</c> with the correct <c>beam.debug.smp</c> executable
+      file it will also read the file <c>$ERL_TOP/erts/etc/unix/etp-commands</c>
+      which contains a lot of <c>gdb</c> command for inspecting a beam core
+      dump. For example, the command <c>etp</c> that will print the content of

+    <title>Address Sanitizer</title>
+    <p>
+      <url href="https://clang.llvm.org/docs/AddressSanitizer.html">
+      AddressSanitizer</url> (asan) is an open source programming tool that
+      detects memory corruption bugs such as buffer overflows, use-after-free
+      and memory leaks. AddressSanitizer is based on compiler instrumentation
+      and is supported by both gcc and clang.
+    </p>
+    <p>
+      Similar to the <c>debug</c> emulator, the <c>asan</c> emulator runs slower
+      than normal, about 2-3 times slower. However, it also has a larger memory
+      footprint, about 3 times more memory than normal.
+    </p>
+    <p>
+      To get full effect you should compile both your own NIF/driver code as
+      well as the Erlang emulator with AddressSanitizer instrumentation. Compile
+      your own code by passing option <c>-fsanitize=address</c> to gcc or
+      clang. Other recommended options that will improve the fault
+      identification are <c>-fno-common</c> and <c>-fno-omit-frame-pointer</c>.
+    </p>
+    <p>
+      Build and run the emulator with AddressSanitizer support by using the same
+      procedure as for the debug emulator, except use the <c>asan</c> build

+    <title>Valgrind</title>
+    <p>
+      An even more heavy weight debugging tool is <url
+      href="https://valgrind.org">Valgrind</url>. It can also find memory
+      corruption bugs and memory leaks similar to <c>asan</c>. Valgrind is not
+      as good at buffer overflow bugs, but it will find use of undefined data,
+      which is a type of error that <c>asan</c> cannot detect.
+    </p>
+    <p>
+      Valgrind is much slower than <c>asan</c> and it is incapable at
+      exploiting CPU multicore processing. We therefore recommend <c>asan</c> as
+      the first choice before trying valgrind.
+    </p>
+    <p>
+      Valgrind runs as a virtual machine itself, emulating execution of hardware
+      machine instructions. This means you can run almost any program unchanged
+      on valgrind. However, we have found that the beam executable benefits from
+      being compiled with special adaptions for running on valgrind.
+    </p>
+    <p>
+      Build the emulator with <c>valgrind</c> target the same as is done for
+      <c>debug</c> and <c>asan</c>. Note that <c>valgrind</c> needs to be
+      installed on the machine before the build starts.
+    </p>
+    <p>
+      Run the <c>valgrind</c> emulator directly in the source tree with the
+      <c>cerl</c> script. Set environment variable <c>VALGRIND_LOG_DIR</c> to
+      the directory where the error log files will be generated.

+    <title>rr - Record and Replay</title>
+    <p>
+      Last but not least, the fantastic interactive debugging tool <url
+      href="https://rr-project.org/">rr</url>, developed by Mozilla as
+      open source. <c>rr</c> stands for Record and Replay. While a core dump
+      represents only a static snapshot of the OS process when it crashed, with
+      <c>rr</c> you instead record the entire session, from start of the OS
+      process to the end (the crash). You can then replay that session from
+      within <c>gdb</c>. Single step, set breakpoints and watchpoints, and even
+      <em>execute backwards</em>.
+    </p>
+    <p>
+      Considering its powerful utility, <c>rr</c> is remarkably light weight.
+      It runs on Linux with any reasonably modern x86 CPU. You may get a two
+      times slowdown when executing in recording mode. The big weakness is its
+      inability to exploite CPU multicore processing. If the bug is a race
+      condition between concurrently running threads, it may be hard to
+      reproduce with <c>rr</c>.
+    </p>
+    <p>
+      <c>rr</c> does not require any special instrumented compilation. However,
+      if possible, run it together with the <c>debug</c> emulator, as that will
+      result in a much nicer debugging experience. You run <c>rr</c> in the
+      source tree using the <c>cerl</c> script.
+    </p>
+    <p>
+      Here is an example of a typical session. First we catch the crash in an rr
+      recording session:
+    </p>
+    <pre>
+> <input>$ERL_TOP/bin/cerl -debug -rr</input>
+rr: Saving execution to trace directory /home/foobar/.local/share/rr/beam.debug.smp-1.
+Erlang/OTP 25 [erts-13.0.2]
+
+Eshell V13.0.2  (abort with ^G)
+1> <input>mymod:buggy_nif().</input>
+Segmentation fault</pre>
+    <p>
+      Now we can replay that session with <c>rr replay</c>:
+    </p>
+    <pre>
+> <input>rr replay</input>
+GNU gdb (Ubuntu 9.2-0ubuntu1~20.04.1) 9.2
+:
+(rr) <input>continue</input>
+:
+Thread 2 received signal SIGSEGV, Segmentation fault.
+(rr) <input>backtrace</input></pre>
+    <p>
+      You get the call stack at the moment of the crash. Bad luck, it is
+      somewhere deep down in the garbage collection of the beam. But you manage
+      to figure out that variable <c>hp</c> points to a broken Erlang term.
+    </p>
+    <p>
+      Set a watch point on that memory position and resume execution
+      <em>backwards</em>. The debugger will then stop at the exact position when
+      that memory position <c>*hp</c> was written.
+    </p>
+    <pre>
+(rr) <input>watch -l *hp</input>
+Hardware watchpoint 1: -location *hp
+(rr) <input>reverse-continue</input>
+Continuing.
+
+Thread 2 received signal SIGSEGV, Segmentation fault.</pre>
+    <p>
+      This is a quirk to be aware about. We started by executing forward until
+      it crashed with SIGSEGV. We are now executing backwards from that point,
+      so we are hitting the same SIGSEGV again but from the other
+      direction. Just continue backwards once more to move past it.
+    </p>
+    <pre>
+(rr) <input>reverse-continue</input>
+Continuing.
+
+Thread 2 hit Hardware watchpoint 1: -location *hp
+
+Old value = 42
+New value = 0</pre>
+    <p>
+      And here we are at the position when someone wrote a broken term on the
+      process heap. Note that "Old value" and "New value" are reversed when we
+      execute backwards. In this case the value 42 was written on the heap.
+      Let's see who the guilty one is:

+# * `erl_xcomp_linux_nptl' - `yes|no'. Defaults to `yes' on Linux; otherwise,

+## -- Optional Feature, and Bug Tests ------------------------------------------
+
+## These tests cannot (always) be done automatically when cross compiling. You

+
+## Note that some of these values will override results of tests performed
+## by `configure', and some will not be used until `configure' is sure that
+## it cannot figure the result out.
+
+## The `configure' script will issue a warning when a default value is used.
+## When a variable has been set, no warning will be issued.
+
+# * `erl_xcomp_after_morecore_hook' - `yes|no'. Defaults to `no'. If `yes',
+#   the target system must have a working `__after_morecore_hook' that can be

+#   This is currently only used by unsupported features.
+#erl_xcomp_after_morecore_hook=
+
+# * `erl_xcomp_bigendian' - `yes|no'. No default. If `yes', the target system
+#   must be big endian. If `no', little endian. This can often be
+#   automatically detected, but not always. If not automatically detected,
+#   `configure' will fail unless this variable is set. Since no default
+#   value is used, `configure' will try to figure this out automatically.
+#erl_xcomp_bigendian=
+
+# * `erl_xcomp_clock_gettime_cpu_time' - `yes|no'. Defaults to `no'. If `yes',

+#   that can be used for retrieving process CPU time.

+#   handle both IPv4 and IPv6.
+#erl_xcomp_getaddrinfo=
+
+# * `erl_xcomp_gethrvtime_procfs_ioctl' - `yes|no'. Defaults to `no'. If `yes',
+#   the target system must have a working `gethrvtime()' implementation and
+#   is used with procfs `ioctl()'.
+#erl_xcomp_gethrvtime_procfs_ioctl=
+
+# * `erl_xcomp_dlsym_brk_wrappers' - `yes|no'. Defaults to `no'. If `yes', the
+#   target system must have a working `dlsym(RTLD_NEXT, <S>)' implementation
+#   that can be used on `brk' and `sbrk' symbols used by the `malloc()'
+#   implementation in use, and by this track the `malloc()' implementations
+#   core memory usage. This is currently only used by unsupported features.
+#erl_xcomp_dlsym_brk_wrappers=
+
+# * `erl_xcomp_kqueue' - `yes|no'. Defaults to `no'. If `yes', the target
+#   system must have a working `kqueue()' implementation that returns a file
+#   descriptor which can be used by `poll()' and/or `select()'. If `no' and
+#   the target system has not got `epoll()' or `/dev/poll', the kernel-poll
+#   feature will be disabled.
+#erl_xcomp_kqueue=
+
+# * `erl_xcomp_linux_clock_gettime_correction' - `yes|no'. Defaults to `yes' on
+#   Linux; otherwise, `no'. If `yes', `clock_gettime(CLOCK_MONOTONIC, _)' on
+#   the target system must work. This variable is recommended to be set to
+#   `no' on Linux systems with kernel versions less than 2.6.
+#erl_xcomp_linux_clock_gettime_correction=
+
+# * `erl_xcomp_linux_nptl' - `yes|no'. Defaults to `yes' on Linux; otherwise,
+#   `no'. If `yes', the target system must have NPTL (Native POSIX Thread
+#   Library). Older Linux systems have LinuxThreads instead of NPTL (Linux
+#   kernel versions typically less than 2.6).
+#erl_xcomp_linux_nptl=
+
+# * `erl_xcomp_linux_usable_sigaltstack' - `yes|no'. Defaults to `yes' on Linux;

+#   broken.

+#   LinuxThreads thread libraries (Linux kernel versions typically less than
+#   2.2) used these signals and made them unusable by the ERTS.
+#erl_xcomp_linux_usable_sigusrx=
+
+# * `erl_xcomp_poll' - `yes|no'. Defaults to `no' on Darwin/MacOSX; otherwise,

+## the variables needed below. Then pass the path to the copy of this file as
+## an argument to `otp_build' in the configure stage:
+##   `otp_build configure --xcomp-conf=<FILE>'
+## -----------------------------------------------------------------------------
+
+## Note that you cannot define arbitrary variables in a cross compilation
+## configuration file. Only the ones listed below will be guaranteed to be
+## visible throughout the whole execution of all `configure' scripts. Other
+## variables needs to be defined as arguments to `configure' or exported in
+## the environment.
+
+## -- Variables for `otp_build' Only -------------------------------------------
+
+## Variables in this section are only used, when configuring Erlang/OTP for
+## cross compilation using `$ERL_TOP/otp_build configure'.
+
+## *NOTE*! These variables currently have *no* effect if you configure using
+## the `configure' script directly.
+
+# * `erl_xcomp_build' - The build system used. This value will be passed as
+#   `--build=$erl_xcomp_build' argument to the `configure' script. It does
+#   not have to be a full `CPU-VENDOR-OS' triplet, but can be. The full
+#   `CPU-VENDOR-OS' triplet will be created by
+#   `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_build'. If set to `guess',
+#   the build system will be guessed using
+#   `$ERL_TOP/erts/autoconf/config.guess'.
+erl_xcomp_build=guess
+
+# * `erl_xcomp_host' - Cross host/target system to build for. This value will
+#   be passed as `--host=$erl_xcomp_host' argument to the `configure' script.
+#   It does not have to be a full `CPU-VENDOR-OS' triplet, but can be. The
+#   full `CPU-VENDOR-OS' triplet will be created by
+#   `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_host'.

+## -- Optional Feature, and Bug Tests ------------------------------------------
+
+## These tests cannot (always) be done automatically when cross compiling. You
+## usually do not need to set these variables. Only set these if you really
+## know what you are doing.
+
+## Note that some of these values will override results of tests performed
+## by `configure', and some will not be used until `configure' is sure that
+## it cannot figure the result out.
+
+## The `configure' script will issue a warning when a default value is used.
+## When a variable has been set, no warning will be issued.
+
+# * `erl_xcomp_after_morecore_hook' - `yes|no'. Defaults to `no'. If `yes',
+#   the target system must have a working `__after_morecore_hook' that can be
+#   used for tracking used `malloc()' implementations core memory usage.
+#   This is currently only used by unsupported features.
+#erl_xcomp_after_morecore_hook=
+
+# * `erl_xcomp_bigendian' - `yes|no'. No default. If `yes', the target system
+#   must be big endian. If `no', little endian. This can often be
+#   automatically detected, but not always. If not automatically detected,
+#   `configure' will fail unless this variable is set. Since no default
+#   value is used, `configure' will try to figure this out automatically.
+#erl_xcomp_bigendian=
+
+# * `erl_xcomp_clock_gettime_cpu_time' - `yes|no'. Defaults to `no'. If `yes',
+#   the target system must have a working `clock_gettime()' implementation
+#   that can be used for retrieving process CPU time.
+#erl_xcomp_clock_gettime_cpu_time=
+
+# * `erl_xcomp_getaddrinfo' - `yes|no'. Defaults to `no'. If `yes', the target

+#   handle both IPv4 and IPv6.
+#erl_xcomp_getaddrinfo=
+
+# * `erl_xcomp_gethrvtime_procfs_ioctl' - `yes|no'. Defaults to `no'. If `yes',
+#   the target system must have a working `gethrvtime()' implementation and
+#   is used with procfs `ioctl()'.
+#erl_xcomp_gethrvtime_procfs_ioctl=
+
+# * `erl_xcomp_dlsym_brk_wrappers' - `yes|no'. Defaults to `no'. If `yes', the
+#   target system must have a working `dlsym(RTLD_NEXT, <S>)' implementation
+#   that can be used on `brk' and `sbrk' symbols used by the `malloc()'
+#   implementation in use, and by this track the `malloc()' implementations
+#   core memory usage. This is currently only used by unsupported features.
+#erl_xcomp_dlsym_brk_wrappers=
+
+# * `erl_xcomp_kqueue' - `yes|no'. Defaults to `no'. If `yes', the target
+#   system must have a working `kqueue()' implementation that returns a file
+#   descriptor which can be used by `poll()' and/or `select()'. If `no' and
+#   the target system has not got `epoll()' or `/dev/poll', the kernel-poll
+#   feature will be disabled.
+#erl_xcomp_kqueue=
+
+# * `erl_xcomp_linux_clock_gettime_correction' - `yes|no'. Defaults to `yes' on
+#   Linux; otherwise, `no'. If `yes', `clock_gettime(CLOCK_MONOTONIC, _)' on

+#   `no' on Linux systems with kernel versions less than 2.6.
+#erl_xcomp_linux_clock_gettime_correction=
+
+# * `erl_xcomp_linux_nptl' - `yes|no'. Defaults to `yes' on Linux; otherwise,
+#   `no'. If `yes', the target system must have NPTL (Native POSIX Thread
+#   Library). Older Linux systems have LinuxThreads instead of NPTL (Linux
+#   kernel versions typically less than 2.6).
+#erl_xcomp_linux_nptl=
+
+# * `erl_xcomp_linux_usable_sigaltstack' - `yes|no'. Defaults to `yes' on Linux;

+#   system. `sigaltstack()' on Linux kernel versions less than 2.4 are
+#   broken.

+
+# * `erl_xcomp_linux_usable_sigusrx' - `yes|no'. Defaults to `yes'. If `yes',
+#   the `SIGUSR1' and `SIGUSR2' signals must be usable by the ERTS. Old
+#   LinuxThreads thread libraries (Linux kernel versions typically less than
+#   2.2) used these signals and made them unusable by the ERTS.
+#erl_xcomp_linux_usable_sigusrx=
+
+# * `erl_xcomp_poll' - `yes|no'. Defaults to `no' on Darwin/MacOSX; otherwise,
+#   `yes'. If `yes', the target system must have a working `poll()'
