APACHE PORTABLE RUNTIME (APR) LIBRARY STATUS: -*-text-*-
Last modified at [$Date: 2001/02/18 00:32:16 $]
Release:
2.0a9 : released December 12, 2000
2.0a8 : released November 20, 2000
2.0a7 : released October 8, 2000
2.0a6 : released August 18, 2000
2.0a5 : released August 4, 2000
2.0a4 : released June 7, 2000
2.0a3 : released April 28, 2000
2.0a2 : released March 31, 2000
2.0a1 : released March 10, 2000
RELEASE SHOWSTOPPERS:
* Unix apr_stat/lstat/getfileinfo were very fast hacks, needs review.
Will suggests: Unix is looking pretty good. Ignore APR_FINFO_NAME
issues for b1, I've noted that issue below.
* OS2 apr_stat/lstat/getfileinfo/dir_read were very fast hacks, need
cleanup, toggle messy (APR_INCOMPLETE) result when appropriate.
RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
* Solve Win32 APR_CHR, APR_BLK, etc for Win32 apr_stat without
GetFileType? How about inode/dev/nlink?
Status: Will's WIP
* SysV semaphore support isn't usable by Apache when started as
root because we don't have a way to allow the semaphore to be
used by the configured User and Group. Current work-around:
change the initial permissions to 0666. Needed code: See
1.3's http_main.c, SysV sem flavor of accept_mutex_init().
Status: Jim will look into this
* Build scripts do not recognise AIX 4.2.1 pthreads
* Win32: Implement apr_shm_ functions
* FirstBill says we need a new procattr, APR_CREATE_SUSPENDED (or
something similar) to direct ap_create_process to create the
process suspended. We also need a call to wake up the suspended
process This may not be able to be implemented everywhere though.
Status: OtherBill asks, why? What is the benefit, how is it
portably implemented? Unless this creates some tangible that
mirrors another platform, then I'm -1.
* Replace tables with a proper opaque ADT that has pluggable
implementations (including something like the existing data type,
plus hash tables for speed, with options for more later).
Status: fanf is working on this.
* add a version number to apr_initialize() as an extra failsafe against
(APR) library version skew.
MsgID: <Pine.LNX.4.10.10005231712380.31927-100000@nebula.lyra.org>
Status: Greg +1 (volunteers), Jeff +1, Ryan +1, Tony -0(?), david +1
* The MM library is built as static and shared library. This should
be set up to build only the required version.
* add apr_crypt() and APR_HAS_CRYPT for apps to determine whether the
crypt() function is available, and a way to call it (whether it is
located in libc, libcrypt, or libufc)
Status: Greg +1 (volunteers)
* apr_create_lock() changes:
- It ignores the "type" parameter, so toss it.
- The fname param is allowed to be NULL on the Unix platform.
Change it to always use the passed value, and check callers.
rbb says: The type parameter is supposed to be used to determine
if we are working with a read/write lock or a mutex.
The fname parameter is essentially required if you
want to be portable, but I dislike wasting cycles to
outsmart the programmer.
Status: david +1
rbb -1
* configure.in does post-processing on the AC_OUTPUT files (for
VPATH support). This means that config.status doesn't do the
right thing when you re-run it. We ought to revamp the makefiles
to do the right AC_SUBST stuff rather than depend upon rewriting.
Sascha: As the rewriter is a crude hack, I would not worry too
much about it. It is designed to go away once we have
a proper build system in place.
One of the perceived deficiencies of automake is that it
uses AC_SUBST too often, thereby slowing down the task of
generating Makefiles significantly, because it applies
dozens of substitutions to each Makefile. And why? Make's
built-in macro processing is much more powerful, and
combined with the include facility, generating Makefiles
becomes simpler and faster.
* use os_(un)cork in network_io/unix/sendrecv.c for FreeBSD's
sendfile implementation.
david: The socket options stuff is now in and using it should
reduce the number of syscalls that are required for
os_cork and uncork, so the code should be reviewed to
make use of the new calls. If no-one beats me to it I'll
get around to it soonish...
* toss the per-Makefile setup of INCLUDES; shift to rules.mk.in
* Change the return type of apr_hash_count() to some counter type
(like "int") instead of a size type (apr_size_t). Jeff will
do this Real Soon Now (so he says on 20010121).
* add the rest of the pool accessor declare/impl macros.
Status: Greg volunteers
* I think apr_open_stderr() and friends dup() the descriptor. That
would allow the new/returned file to be closed (via pool cleanup
or manually) without accidentally closing stderr/out.
* need to export the shared library extension (e.g. ".so") for the
platform. clients need to use this to construct filenames to
pass to apr_dso_load()
Documentation that needs writing:
* API documentation
Stuff waiting for code thawing after Beta 1:
* Implement APR_FINFO_ICASE/APR_FINFO_NAME for stat'ish calls.
Can wait till after b1, will be required to eliminate canonical
and add that functionallity in-line with directory_walk, which
is _not_ planned for 2.0b1, but immediately afterwards. It's
required to complete Apache/WinNT's Unicode schema as well.
Note: Will doesn't like his original APR_FINFO_ICASE definition.
* Identify and implement those protection bits that have general
usefulness, perhaps hidden, generic read-only [immutable],
effective current user permissions, etc.
