a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync Jeff says: We can't do anything about libtool since AIX
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync needs a version that won't work on some
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync platforms. Handle this in the README.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync The binbuild issue isn't AIX. It is
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync something that could happen anywhere that
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync the binbuild-er has their own expat.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync Handle this by patching binbuild.sh for a
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync beta roll or putting a patch in the README for
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync use by people who want to do binbuild but
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync have expat installed locally.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync gregames: why can't we roll a second tarball with the
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync appropriate libtool version? doesn't
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync Darwin need it as well as AIX?

a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync the debugger interferes with reproducing the bug.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync Perhaps in FirstBill's example _restart didn't survive.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync . Scoreboard appears irrelevant to the problem.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync . This looks like handle corruption in NT/XP

a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync * mod_auth_dbm can't open a Berkeley DB password file on Unix
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync Justin postulates that this might be related to the fact
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync that mod_auth_dbm wasn't using apr-util. See
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync modules/aaa/mod_auth_dbm.c revision 1.42 and
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync module/aaa/config.m4 revision 1.54. Also, FreeBSD's DB
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync variant was not properly detected. See
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync apr-util/build/apu-conf.m4 revision 1.31 and
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync apr-util/dbm/apr_dbm_berkeleydb.c revision 1.17.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync * Madhu reports that the worker MPM doesn't shutdown nicely
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync after a stress test.
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync * mod_autoindex displays the wrong icon for subdirectories
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync on Unix
a734c64bff58bda2fa48c2795453e092167b0ff7vboxsync possible fix in modules/generators/mod_autoindex.c r1.93.
* anon shared memory not allocating enough
(fix is apr/shm/unix/shm.c 1.14)
FINAL RELEASE SHOWSTOPPERS:
* ap_directory_walk skips some per-dir config merge functions
if there is no "<Directory />" block in the configuration
Message-ID: <m3itbdiijq.fsf@rdu163-40-092.nc.rr.com>
* That is very unlikely, merges are additive. Much more likely,
the default SetOutputFilter default or merge is borked.
Unless it's the code that permits 'null' merges, per module.
Still, it's probably in SetOutputFilter's behavior.
* BrianP notes: directory_walk's handling of trailing slashes
appears to be the cause: <3C1CF721.1090300@pacbell.net>
* If any request gets to the core handler, without a flag that this
r->filename was tested by dir/file_walk, we need to 500 at the very
end of the ap_process_request_internal() processing. This provides
authors of older modules better compatibility, while still improving
the security and robustness of 2.0.
Status: still need to decide where this goes, OtherBill comments...
Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
we need to look at halting this in the 'default handler' case,
and that implies pushing the 'handler election' into the request
internal processing phase from the run request phase.
* Convert all instances of the old apr_lock_t type to the new
types (once they are fully supported in APR).
Status: Aaron is working on converting INTRAPROCESS
to apr_thread_mutex_t types. Full replacements for
LOCKALL and CROSS_PROCESS are not yet complete on all
platforms, and should only be used in MPMs like worker
with limited OS exposure.
BrianP asks: "Is this really a showstopper?"
IanH says: "If we don't do it before we go live we will have 2
different API's to support in APR"
* [Ken] Test suite failures:
o worker is also failing some of the 'cgi' subtests
(see <URL:http://Source-Zone.Org/Apache/regression/>):
Justin says: "Worker should be fine and passes httpd-test here.
If you can provide evidence that it can be reproduced
outside of httpd-test, then it's a showstopper. I
think it's a perl or a httpd-test problem."
Not a showstopper: Justin
* [Ken] A binbuild installation picks up the right libraries when
running apachectl because we set the appropriate environment
variable, but ab, htpasswd, etc. don't know how to pick up apr,
apr-util, etc.
Message-ID: <20020116000226.GA15991@ebuilt.com>
Justin says: "You could always build all of the binaries
statically if you don't want to let libtool
handle it. At most, I don't consider this a
a release showstopper as it is a packaging issue."
Ken sez: "Showstopper because, until it's the default, it
violates the P of LA. Binaries will give strange
errors and not run if moved."
Status: Aaron volunteers: I'll commit a patch to allow all
the support binaries to be built statically against
libapr/libaprutil/etc and then enable it in binbuild.
gregames says: what about httpd? yeah, it works at the moment
if you use apachectl. But I've already heard
complaints about not being able to execute
httpd directly.
CURRENT VOTES:
* Should we always build binaries statically unless otherwise
indicated?
Message-ID: <20020129210006.B23512@Lithium.MeepZor.Com>
+1: Ken
-1: Justin, Ian
* If the parent process dies, should the remaining child processes
"gracefully" self-terminate. Or maybe we should make it a runtime
option, or have a concept of 2 parent processes (one being a
"hot spare").
See: Message-ID: <3C58232C.FE91F19F@Golux.Com>
Self-destruct: Ken, Martin
Not self-destruct: BrianP, Ian, Cliff, BillS
Make it runtime configurable: Aaron, Jim, Justin
Have 2 parents: +1: Jim
-1: Justin
+0: Martin (while standing by, could it do
something useful?)
look at accept() error handling first: gregames
* 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)
RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
* Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be
removed if possible.
Message-ID: <Pine.LNX.4.33.0201202232430.318-100000@deepthought.cs.virginia.edu>
* There is a bug in how we sort some hooks, at least the pre-config
hook. The first time we call the hooks, they are in the correct
order, but the second time, we don't sort them correctly. Currently,
the modules/http/config.m4 file has been renamed to
modules/http/config2.m4 to work around this problem, it should moved
back when this is fixed. rbb
Justin says: "Is this really a showstopper? This has been here
forever. What's wrong? Does this have to do with
autoconf or m4?"
Not a showstopper: Justin, BrianP, trawick, gregames
* The Add...Filter and Set...Filter directives do not allow the
administrator to order filters, beyond the order of filename (mime)
extensions. It isn't clear if Set...Filter(s) should be inserted
before or after the Add...Filter(s) which are ordered by sequence of
filename extensions. At minimum, some sort of +-[0-10] syntax seems
like the quickest fix for a 2.0 gold release.
Justin says: "Could we delay this for a point release or 2.1?"
Not a showstopper: justin, wrowe, trawick, stoddard, Jim, Ian, Aaron,
gregames
* Make some modifications to the scoreboard creation routines,
prefer anonymous shared memory, and allow a configuration
directive to override the defaults.
Message-ID: <20020130080804.C16977@clove.org>
Status: Aaron volunteers
* 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:
Message-ID: <20020111115006.K1529@clove.org>
* 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."
gregames says: I see the breakage now, and volunteer to fix it
when things calm down a little. It looks OK when
there are complete lines and no mime continuations.
* 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
Status: Ken asks, didn't Jeff fix this when he fixed the queue
overrun?
* 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.
Message-ID: <Pine.BSF.4.20.0104031557420.20876-100000@alive.znep.com>
* 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.
* Fix the worker MPM to use POD to kill child processes instead
of ap_os_killpg, regardless of how they should die. (Ryan Bloom)

needed. Apache 1.3 just never stashed "multipart" into

multipart content-type; the other code should still think it is
dealing with the <orig_ct> stuff.
