5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync needs a version that won't work on some
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync platforms. Handle this in the README.
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync The binbuild issue isn't AIX. It is
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync something that could happen anywhere that
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync the binbuild-er has their own expat.
20fc4a350a4a8e56ffaac6cf57dcd677a7ac36c5vboxsync Handle this by patching binbuild.sh for a
20fc4a350a4a8e56ffaac6cf57dcd677a7ac36c5vboxsync beta roll or putting a patch in the README for
1a61b0d8c05e69787e6ac1d38f0a46ef572ede7dvboxsync use by people who want to do binbuild but

5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync score is suspect. OtherBill is investigating, definately
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync a showstopper for a .31/.32 beta. Progress report later today.

5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync * ap_directory_walk skips some per-dir config merge functions
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync if there is no "<Directory />" block in the configuration

5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync * That is very unlikely, merges are additive. Much more likely,
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync the default SetOutputFilter default or merge is borked.
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync Unless it's the code that permits 'null' merges, per module.
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync Still, it's probably in SetOutputFilter's behavior.
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync * BrianP notes: directory_walk's handling of trailing slashes
17d67aeb3722c094c6493a3e9a9d0cdfb9453ecdvboxsync appears to be the cause: http://www.apachelabs.org/apache-mbox/200112.mbox/%3c3C1CF721.1090300@pacbell.net%3e

5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync * Test suite failures:
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync o worker is also failing some of the 'cgi' subtests
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync (see <URL:http://Source-Zone.Org/Apache/regression/>):
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync Justin says: "Worker should be fine and passes httpd-test here.
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync If you can provide evidence that it can be reproduced
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync outside of httpd-test, then it's a showstopper. I
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync think it's a perl or a httpd-test problem."
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync Not a showstopper: Justin
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync * If any request gets to the core handler, without a flag that this
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync r->filename was tested by dir/file_walk, we need to 500 at the very
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync end of the ap_process_request_internal() processing. This provides
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync authors of older modules better compatibility, while still improving
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync the security and robustness of 2.0.
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync Status: still need to decide where this goes, OtherBill comments...

f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync we need to look at halting this in the 'default handler' case,
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync and that implies pushing the 'handler election' into the request
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync internal processing phase from the run request phase.
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync * There is a bug in how we sort some hooks, at least the pre-config
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync hook. The first time we call the hooks, they are in the correct
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync order, but the second time, we don't sort them correctly. Currently,
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync the modules/http/config.m4 file has been renamed to
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync modules/http/config2.m4 to work around this problem, it should moved
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync back when this is fixed. rbb

7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync forever. What's wrong? Does this have to do with
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync autoconf or m4?"

5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync * Convert all instances of the old apr_lock_t type to the new
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync types (once they are fully supported in APR).
0c587d7af645db20acefebcfc15b6f46c440ba4avboxsync Status: Aaron is working on converting INTRAPROCESS
0c587d7af645db20acefebcfc15b6f46c440ba4avboxsync to apr_thread_mutex_t types. Full replacements for
0c587d7af645db20acefebcfc15b6f46c440ba4avboxsync LOCKALL and CROSS_PROCESS are not yet complete on all
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync platforms, and should only be used in MPMs like worker
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync with limited OS exposure.

f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync * A binbuild installation picks up the right libraries when
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync running apachectl because we set the appropriate environment
f5ab5688c35373443d953e2a9fa8a054defdece8vboxsync variable, but ab, htpasswd, etc. don't know how to pick up apr,

5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync Justin says: "You could always build all of the binaries
7eaaa8a4480370b82ef3735994f986f338fb4df2vboxsync statically if you don't want to let libtool
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync handle it. At most, I don't consider this a
5f9dfb422a6ed57822f9c0cb94fa7df8d24acc9bvboxsync a release showstopper as it is a packaging issue."
17d67aeb3722c094c6493a3e9a9d0cdfb9453ecdvboxsync Ken sez: "Showstopper because, until it's the default, it
17d67aeb3722c094c6493a3e9a9d0cdfb9453ecdvboxsync violates the P of LA. Binaries will give strange
17d67aeb3722c094c6493a3e9a9d0cdfb9453ecdvboxsync errors and not run if moved."
17d67aeb3722c094c6493a3e9a9d0cdfb9453ecdvboxsync Status: Aaron volunteers: I'll commit a patch to allow all
17d67aeb3722c094c6493a3e9a9d0cdfb9453ecdvboxsync the support binaries to be built statically against
17d67aeb3722c094c6493a3e9a9d0cdfb9453ecdvboxsync libapr/libaprutil/etc and then enable it in binbuild.

87c50c527af59e43745475c4b8ac907c5f9bc204vboxsync * The Add...Filter and Set...Filter directives do not allow the
87c50c527af59e43745475c4b8ac907c5f9bc204vboxsync administrator to order filters, beyond the order of filename (mime)
87c50c527af59e43745475c4b8ac907c5f9bc204vboxsync extensions. It isn't clear if Set...Filter(s) should be inserted
87c50c527af59e43745475c4b8ac907c5f9bc204vboxsync before or after the Add...Filter(s) which are ordered by sequence of
87c50c527af59e43745475c4b8ac907c5f9bc204vboxsync filename extensions. At minimum, some sort of +-[0-10] syntax seems

* Get perchild to work on platforms other than Linux. This
will require a portable mechanism to pass data and file/socket
descriptors between vhost child groups. An API was proposed
on dev@apr:

* Recent changes to ap_rgetline may have broken EBCDIC boxes.
Message-ID: <20020122072605.GF28051@ebuilt.com>
Justin says: "I don't have an EBCDIC box to test on. A potential
solution is to split out ap_rgetline into two
functions as described in this message."
* Modify the worker MPM so that it doesn't need to create and
destroy a pool for each request--possibly by adopting a
leader/follower model in which each worker owns a persistent
ptrans pool (like the prefork MPM) and the workers take
turns acting as listeners...this approach might also help
reduce context-switching
* CGI single-byte reads
BrianP suggests that this is caused by the ap_scan_script_header_err()
routine, which will do single-byte reads until it finds the end
of the header, at which point it constructs a pipe-bucket (buffered)
to read from.
Proposed solution in:
Message-ID: <3C36ADAF.60601@cnet.com>
* Try to get libtool inter-library dependency code working on AIX.
Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
Justin says: If we get it working on AIX, we can enable this
on all platforms and clean up our build system
somewhat.
Jeff says: I thought I tested a patch for you sometime in
January that you were going to commit within a few
days.
* Handling of %2f in URIs. Currently both 1.3 and 2.0
completely disallow %2f in the request URI path (see
ap_unescape_url() in util.c). It's permitted and passed
through in the query string, however. Roy says the
original reason for disallowing it, from five years ago,
was to protect CGI scripts that applied PATH_INFO to
a filesystem location and which might be tricked by
..%2f..%2f(...). We *should* allow path-info of the
form 'http://foo.com/index.cgi/path/to/path%2finfo'.
Since we've revamped a lot of our processing of path
segments, it would be nice to allow this, or at least
allow it conditionally with a directive.
* FreeBSD, threads, and worker MPM. All seems to work fine
if you only have one worker process with many threads. Add
a second worker process and the accept lock seems to be
lost. This might be an APR issue with how it deals with
the child_init hook (i.e. the fcntl lock needs to be resynced).
More examination and analysis is required.
Status: This has also been reported on Cygwin.
Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
Justin says: So, FreeBSD-CURRENT and Cywin have the same
problem. Yum. If another platform has this
with worker, this becomes a showstopper.
Aaron says: I spent some time disecting this and have come to
the conclusion that it is not a problem in the worker MPM
(or at least, it is not isolated to a problem in worker).
I'll list some of the problems I'm seeing in case someone
else wants to pick up where I've left off:
- Delivery of just about any signal to one of the child
processes will send it into an infinite loop as well.
- Even though the parent is spinning out of control,
at first the child or children will appear to work
properly. At times it is possible to get it into a state,
however, where a request will hang until another concurrent
request "kicks" the first, at which point the second will
hang. My theory is that this has to do with the
pthread_cond_*() implementation in FreeBSD, but it's still
possible that it is in APR.
Justin adds: Oh, FreeBSD threads are implemented entirely with
select()/poll()/longjmp(). Welcome to the nightmare.
So, that means a ktrace output also has the thread
scheduling internals in it (since it is all the same to
the kernel). Which makes it hard to distinguish between
our select() calls and their select() calls.
*bangs head on wall repeatedly* But, some of the libc_r
files have a DBG_MSG #define. This is moderately helpful
when used with -DNO_DETACH. The kernel scheduler isn't
waking up the threads on a select(). Yum. And, I bet
those decrementing select calls have to do with the
scheduler. Time to brush up on our OS fundamentals.
* There is increasing demand from module writers for an API
that will allow them to control the server � la apachectl.
Reasons include sole-function servers that need to die if
an external dependency (e.g., a database) fails, et cetera.
Perhaps something in the (ever more abused) scoreboard?
rbb: I don't believe the scoreboard is the correct mechanism
for this. We already have a pipe that goes between parent
and child for graceful shutdown events, along with an API that
can be used to send a message down that pipe. In threaded MPMs,
it is easy enough to make that one pipe be used for graceful
and graceless events, and it is also easy to open that pipe
to both parent and child for writing. Then we just need to figure
out how to do graceless on non-threaded MPMs.
* revamp the input filter behavior, per discussions since
February (and especially at the hackathon last
April). Specifically, ap_get_brigade will return a brigade with
*up to* a specific number of bytes, or a "line" of data. The
read may be blocking or nonblocking. ap_getline() will be
refactored into apr_brigade_getline(), and then DECHUNK can use
f->next (ap_getline will always read "top of input stack"). Also
fix the bug where request body content will end up closing the
connection (buggering up persistent conns).
Status: Justin is working on this as fast as he can.
The core input filters, HTTP-related filters, mod_ssl,
mod_proxy, and ap_[r]getline are switched to the new logic.
- socket bucket and core input filter changes. see end of
message ID (Feb 27): <20010227075326.S2297@lyra.org>

* Allow the DocumentRoot directive within <Location > scopes? This
allows the beloved (crusty) Alias /foo/ /somepath/foo/ followed
by a <Directory /somepath/foo> to become simply
<Location /foo/> DocumentRoot /somefile/foo (IMHO a bit more legible
and in-your-face.) DocumentRoot unset would be accepted [and would
not permit content to be served, only virtual resources such as
server-info or server-status.
This proposed change would _not_ depricate Alias.
* Win32: Rotatelogs sometimes is not terminated when Apache
goes down hard. FirstBill was looking at possibly tracking the
child's-child processes in the parent process.
OtherBill asks, wasn't this fixed?
stoddard: Not fixed. Shared scoreboard might offer a good
way for the parent to keep track of 'other child' processes
and whack them if the child goes down.
* Win32: Add a simple hold console open patch (wait for close or
the ESC key, with a nice message) if the server died a bad
death (non-zero exit code) in console mode.
Resolution: bring forward same ugly hacks from 1.3.13-.20
* Port of mod_ssl to Apache 2.0:
The current porting state is summarized in modules/ssl/README. The
remaining work includes:
(1) stablizing/optimizing the SSL filter logic
(2) Enabling the various SSL caching mechanisms (shmcb, shmht)
(3) Enabling SSL extentions
(4) Trying to seperate the https filter logic from mod_ssl -
This is to facilitate other modules that wish to use the https
filter or the mod_ssl logic or both as required.
Justin: mod_ssl filter logic is redone, so that should be fine.
Madhu has submitted a patch for SSL caching - however, I
am -0 on that patch as I *think* we could implement the
shared memory another way that is much cleaner (i.e.
treat shmem directly as a dbm via APR routines). Justin
also thinks that the https filter logic may be sufficiently
decoupled now, but isn't really sure.
* Performance & Debug: Eliminate most (and perhaps all) of the
malloc/free calls in the bucket brigade code. Need some
light weight memory management functions that allow freeing
memory (putting it back into a memory pool) when it is no
longer needed. Enabling simple debugging features like guard
bands, double free detection, etc. would be cool but certainly
not a hard requirement.
Status: Cliff started to implement this using SMS as has
been discussed at length for months, but since
SMS is not being used anywhere else in the server,
several people expressed the opinion that we should
get rid of it entirely, meaning that the buckets
need their own memory management (free list) functions.
Cliff will implement that this weekend so we at least
have something to look at/compare with.
* Eliminate unnecessary creation of pipes in mod_cgid
* the autoconf setup should be fixed to default to using the
"Apache" layout from config.layout, and each variable settable
in a layout should be overridable on the command line. Plus,
what we do right now just doesn't seem to fully fit into how autoconf
works, eg. AC_PREFIX_DEFAULT issues.

* Combine log_child and piped_log_spawn. Clean up http_log.c.
Common logging API.
* Document mod_file_cache.
* Platforms that do not support fork (primarily Win32 and AS/400)
Architect start-up code that avoids initializing all the modules
in the parent process on platforms that do not support fork.
* Win32: Migrate the MPM over to use APR thread/process calls. This
would eliminate some code in the Win32 branch that essentially
duplicates what is in APR.
* There are still a number of places in the code where we are
losing error status (i.e. throwing away the error returned by a
system call and replacing it with a generic error code)
* Mass vhosting version of suEXEC.
* All DBMs suffer from confusion in support/dbmmanage (perl script) since
the dbmmanage employs the first-matched dbm format. This is not
necessarily the library that Apache was built with. Aught to
rewrite dbmmanage upon installation to bin/ with the proper library
for predictable mod_auth_dbm administration.
Questions; htdbm exists, time to kill dbmmanage, or does it remain
useful as a perl dbm management example? If we keep it,
do we address the issue above?
* use apu_dbm in mod_auth_dbm
Status: Greg +1 (low-priority volunteer)
Justin says: "Seems like this is already there, so should we just
remove the other DBM code in that file? If you want
to use gdbm, or dbm, etc, you should tell apr-util."
Will says: "bs - I may choose the fastest - most efficient native
dbm implementation, for shared proc caches, ssl session
caching, etc, but that has nothing to do with maintaining
a userlist via dbm, which has to remain readable between
builds/machines, etc. The use-multiple database schema
for apr-util would let us do this with just apr, though."
Ian says: "multi-dbm is in, but it still has ndbm support hardcoded
is this still required? isn't ndbm supported via gdbm?"
* Integrate mod_dav.
Some additional items remaining:
- case_preserved_filename stuff
(use the new canonical name stuff?)
- find a new home for ap_text(_header)
- is it possible to remove the DAV: namespace stuff from util_xml?
* ap_core_translate() and its use by mod_mmap_static and mod_file_cache
are a bit wonky. The function should probably be exposed as a utility
function (such as ap_translate_url2fs() or ap_validate_fs_url() or
something). Another approach would be a new hook phase after
"translate" which would allow the module to munge what the
translation has decided to do.
Status: Greg +1 (volunteers), Ryan +1
* Explore use of a post-config hook for the code in http_main.c which
calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
ap_sort_hooks() [to reduce the logic in main()]
* read the config tree just once, and process N times (as necessary)
* (possibly) use UUIDs in mod_unique_id and/or mod_usertrack
* (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
into a VirtualHost container) to 2.0.
* shift stuff to mod_core.h
* callers of ap_run_create_request() should check the return value
for failure (Doug volunteers)
* Win32: Get Apache working on Windows 95/98. The following work
(at least) needs to be done:
- winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT
specific code that is still not in NT only code paths
- IOL binds to APR sendfile, implemented with TransmitFile, which
is not available on 95/98.
- Document warning that OSR2 is required (for Crypt functions, in
rand.c, at least.) This could be resolved with an SSL library, or
randomization in APR itself.
- Bring the Win9xConHook.dll from 1.3 into 2.0 (no sense till it
actually works) and add in a splash of Win9x service code.
* In order to use a DSO version of mod_ssl we have to link with
-lssl and -lcrypto. A workaround is in place right now where the
entire EXTRA_LIBS macro is being appended to the objects list, but
this is a hack. We should either revamp the APACHE_CHECK_SSL_TOOLKIT
autoconf function or come up with some other autoconf checks to
search for libssl and libcrypto and properly add them to mod_ssl's
link flags.
* Make the worker MPM the default MPM for threaded Unix boxes.
+1: Justin, Jeff, Ian
-0: Aaron (premature decision, needs more discussion), Lars
-0: Cliff (I think the default config should be the safest possible)
* Fix the worker MPM to use POD to kill child processes instead
of ap_os_killpg, regardless of how they should die. (Ryan Bloom)
