Contributors looking for a mission:
* just do an egrep on "TODO", "XXX" and see what's there
[ please place file names and revisions from HEAD here, so it is easy to
identify exactly what the proposed changes are! ]
* Forward port: Escape special characters (especially control
characters) in mod_log_config to make a clear distinction between
client-supplied strings (with special characters) and server-side
strings. This was already introduced in version 1.3.25.
A ready-for-commit patch for 2.0 can be found under

nd: since it's inherited carefully (namely: not) and has to
be explicitely turned on, I see no harm with that patch.
(needs docs anyway!)
wrowe: two open questions, one about dconf v.s. sconf and
the other about proxied requests containing %2f,
posted to the dev@ list with Message-ID
* Rewrite how proxy sends its request to allow input bodies to
morph the request bodies. Previously, if an input filter
changed the request body, the original C-L would be sent which
would be incorrect.
Due to HTTP compliance, we must either send the body T-E: chunked
or include a C-L for the request body. Connection: Close is not
an option. [jerenkrantz 2002/12/08 21:37:27]

Alias /manual/en /path/to/manual
Alias /manual/de /path/to/manual
SetEnvIf Request_URI ^/manual/en/ prefer-language=en
SetEnvIf Request_URI ^/manual/de/ prefer-language=de
into the distributed config (but with regexps). We're going to get
an intelligent system for choosing the language either by user's
choice or language negotiation. If user's choice doesn't exist, it
falls back to negotiation again.

We need to decide what happens with unparsable qvalues. RFC 2616

+1: wrowe
* Fix the SSLMutex config parser so that all 'mechanisms' can take
a filename, even if ignored, and they are rooted to the full path
to the server (except for posixsem locks). This allows a very
cross-platform default:logs/ssl_mutex to be used everywhere. Also
eliminates the '.pid' suffix so that the name given is the name.
Allows Win32 and other non-unicies to use named locks.

NO_MD5, NO_IDEA and NO_MDC2 (won't compile otherwise with 0.9.7+ and
restricted crypto algorithms)

* Backwards compatibility is expected of future Apache 2.0 releases,
such that no MMN major number changes will occur until 2.1.
* All commits to APACHE_2_0_BRANCH must be reflected in cvs HEAD
as well, if they apply. Logical progression is commit to HEAD,
get feedback and then commit to APACHE_2_0_BRANCH.
* APACHE_2_0_BRANCH *has* to work with an official stable version
of APR (i.e., 1.0).
no: trawick, jerenkrantz, wrowe, stoddard, striker, nd, gregames
wrowe: it's nice if we *can* compile against it, but as a
matter of a practical tarball or binary release, don't.
gstein: the Q is unclear. of course it has to work with an
official version. maybe the Q is really "we *require*
a stable version" ?
* APACHE_2_0_BRANCH uses a level of apr and apr-util code branched
from the APACHE_2_0_44 tag.
yes: trawick, jerenkrantz, striker, nd, gregames
(but nd doesn't branch anything in apr repos)
no: wrowe
(objection remains the same, APR 0.9 is pretty much in 'bugfix'
mode, all such bugfixes are helpful to the httpd project; some
on the APR list have suggested branching APR 0.10.x when some
new code comes along. Again, wrowe suggests the option below
is sufficient as long as eyeballs remain on binary compat.)
* APACHE_2_0_BRANCH uses a level of APR code versioned 0.9.2-dev
or later (to 0.9.9), so long it remains binary compatible.
yes: wrowe
(wrowe suggests that when apr chooses to break compatibility,
httpd would continue to use that last compatible build. It's
in the httpd project's interest to participate instead of fork
APR efforts.)
* Develop in Review-Then-Commit or Commit-Then-Review mode
on APACHE_2_0_BRANCH (no vetoes, this is a straight vote.)
R-T-C: trawick, wrowe, jerenkrantz, stoddard, rederpj, striker, nd,
gregames(lazy consensus OK for mainline), jwoolley
C-T-R: BrianP, aaron, jim, gstein, bnicholes
gstein: we have an open branch, so there is an easy release
valve for feature and API changes. we trust developers
to put their changes in the right place. if they
*don't*, that is what the -T-R is all about, and why we
have source control.
yes, the branch should be "bug fix only" or other
voted-upon feature changes, but we already have
guidelines for all that.
see the section titled "Product Changes" and the
following paragraph which states:
"... All product changes to a prior-branch (old
version) repository require consensus before the change
is committed."
And under "When to Commit a Change", first line:
"Ideas must be review-then-commit; patches can be
The problem here is that R-T-C expresses a fundamental
DISTRUST of your peers. We had problems stabilizing the
code simply because there are numerous interests in the
codebase, and those are not fully compatible. With the
branch, we have partitioned the interest: bug fix vs
new features. But developers *know* when a bug fix
should be applied or should not. There is no reason to
tell a developer they are wrong, and their basic
understanding of what is broken and what needs to be
fixed is subject to peer review. Once you have a bug
fix in hand, it isn't rocket science. And, always,
there is the option to pull a fix back out if a
developer goofs. We all goof, but there is no sense in
ASSUMING that incorrect behavior is the norm.
If a develop consistently causes problems, then we have
ways of dealing with that. But at the moment, this
isn't the case, and it does not foster a healthy
environment to apply that label to ALL developers.
R-T-C is fundamentally "you're guilty of bad behavior,
with no way to prove innocence. all your actions are
hereby monitored."
Why did I wait so long to issue this commentary? Simply
because I disagreed with it at such a fundamental level
that I didn't want to deal with it. Also, that I
*wasn't* going to deal with it when I had changes to
commit. But now we're seeing this stupid R-T-C hammer
being used to smack developers over the head. That is
inappropriate when the bug fixes they are committing to
the branch are entirely reasonable and appropriate. The
hammer simply should not exist.
Yes, I'm ranting, and hey, I'm even sober. :-) R-T-C is
Badness. If I could veto the policy, I would. If I can
ignore it, I will. For years, this group was built on
the notion of peer respect and trust. R-T-C destroys
that, and makes the environment less cozy and less
inviting. Our polcies and procedures were designed to
operate successfully in a C-T-R environment; there is
no need for such a draconian policy.
* httpd-std.conf and friends;
a) httpd-std.conf should be tailored by install (from src or
binbuild) even if user has existing httpd.conf
+1: trawick, slive, gregames, ianh, Ken, wrowe, jwoolley, jim, nd
wrowe - prefer httpd.default.conf to avoid ambiguity with cvs,
note that win32 installer creates just that file
(.default.conf rather than .conf.default so that win32
can recognize .conf files as text configuration files.)
b) tailored httpd-std.conf should be copied by install to
-0: striker
c) tailored httpd-std.conf should be installed to
sysconfdir/examples or manualdir/exampleconf/
+1: slive, trawick, Ken, nd (prefer the latter)
d) tailored httpd-std.conf should be installed as httpd-std-<version>.conf.
+1: striker
e) Installing a set of default config files when upgrading a server
doesn't make ANY sense at all.
+1: ianh - medium/big sites don't use 'standard config' anyway, as it
usually needs major customizations
-1: Ken, wrowe, jwoolley, jim, nd
wrowe - diff is wonderful when comparing old/new default configs,
even for customized sites that ianh mentions
jim - it makes sense assuming that the default configs
include the updated directives and inline comments
that explain the changes and make the 'diff' more useful.
* 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").

something useful?)
* Make the worker MPM the default MPM for threaded Unix boxes.

+0: BrianP, Aaron (mutex contention is looking better with the
latest code, let's continue tuning and testing), rederpj, jim
-0: Lars, wrowe (let's make this defacto for the 2.2 release.),
nd (for 2.0)
* 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.
OtherBill offers that this is a SERIOUS problem. We do not sort
correctly by the ordering arguments passed to the register hook
functions. This was proven when I reordered the open_logs hook
to attempt to open the error logs prior to the access logs. Possibly
the entire sorting code needs to be refactored.
* pipes deadlock on all platforms with limited pipe buffers (e.g. both
Linux and Win32, as opposed to only Win32 on 1.3). The right solution
is either GStein's proposal for a "CGI Brigade", or OtherBill's proposal
for "Poll Buckets" for "Polling Filter Chains". Or perhaps both :-)
* All handlers should always send content down even if r->header_only
is set. If not, it means that the HEAD requests don't generate the
same headers as a GET which is wrong.
* HP/UX 10.20: compile breakage in APR. Looks like it should be easy
to fix, probably just some extraneous #include's that are fouling
things up.
PR: 9457
Jeff: See my reply and patch in the PR (and previous commit to
stop using "pipe" as a field name). If patch is committed, we
should be okay. I'll wait to see if the user tests the patch.
Update by Jeff 20020722: I got an account on HP 10.20. It looks
like some of the APR thread detection is screwed up. If we find
pthread.h but we can't compile the pthread test program we still
think we can use threads. For that reason, the patch I posted
to the PR won't work as-is since a failed compile of the test
program means nothing.
* exec cmd and suexec arg-passing enhancements
Status: Patches proposed

* The 2.0.36 worker MPM graceless shutdown changes work but are
a bit clunky on some platforms; eg, on Linux, the loop to
join each worker thread seems to hang, and the parent ends up
killing off the child with SIGKILL. But at least it shuts down.
* --enable-mods-shared="foo1 foo2" is busted on Darwin. Pier
posted a patch (Message-ID: <>).
* We do not properly substitute the prefix-variables in the configuration
scripts or generated-configs. (i.e. if sysconfdir is etc,
httpd-std.conf points to conf.)
* If any request gets through ap_process_request_internal() and is
scheduled to be served by 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 so sub_req-esters
know this request cannot be run. 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$495203b0$>
[Deleted comments regarding the ap_run_handler phase, as irrelevant
as BillS points out that "common case will be caught in
default_handler already (with the r->finfo.filetype == 0 check)"
and the issue is detecting this -before- we try to run the req.]
gregames says: can this happen somehow without a broken module
being involved? If not, why waste cycles trying to defend against
potential broken modules? It seems futile.
wrowe counters: no, it shouldn't happen unless the module is broken.
But the right answer is to fail the request up-front in dir/file
walk if the path was entirely invalid; and we can't do that either
UNTIL 2.1 or we break modules that haven't hooked map_to_storage.
* With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me
how the Perchild MPM should be re-written. It hasn't worked
correctly since filters were added because it wasn't possible to
get the content that had already been written and the socket at
the same time. This mode lets us do that, so the MPM can be
* htpasswd blindly processes the file you give it, and does no
sanity checking before totally corrupting whatever file it was

* [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.
I think it's a perl or a httpd-test problem."
* Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be
removed if possible.
Message-ID: <>
Jeff wonders if we still care about this. It is no longer an
API issue but simply an extra trip through the brigade.
* 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 a nice solution. See ROADMAP.
* 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:

* Try to get libtool inter-library dependency code working on AIX.

January that you were going to commit within a few
* 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 ''.
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.
OtherBill adds that %2f as the SECOND character of a multibyte
sequence causes the request to fail! This happens notably in
the ja-jis encoding.
OtherBill is -0.5 for even considering this until 2.2 because
it removes some protection we provided to third party modules
that would mysteriously 'evaporate', exposing potential holes
in security. Putting this change into 2.1 development now (with
strong warnings!) will give authors a chance to vet their code.
* 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.
FreeBSD 4.7 was reputed to have 'fixed' threads. Not.
Message-ID: <> (cygnus)
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 à 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?
On the other hand, 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.
* 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.
stoddard: 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.
Other thoughts on walking the process chain using the NT kernel
have also been proposed on APR.
* Eliminate unnecessary creation of pipes in mod_cgid
* Combine log_child and piped_log_spawn. Clean up http_log.c.
Common logging API.
* 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?
* 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.

* 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)
OtherBill adds that the 'good' solution of three passes against the
config tree within one read is the better solution, but breaks many
modules. Best left for 2.2?
-0.5: OtherBill
* (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:
- 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.
* Fix the worker MPM to use POD to kill child processes instead
of ap_os_killpg, regardless of how they should die.
* Scoreboard structures could be changed in the future such that
proper alignment is not maintained, leading to segfaults on
some systems. Cliff posted a patch to deal with this issue but
later recanted. See this message to
Message-ID: <Pine.LNX.4.44.0203011354090.16457-200000@deepthought>
* 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.
* SSL renegotiations in combination with POST request
* Port or dispose all code inside #if 0...#endif blocks that remain
from the porting effort.
* Do we need SSL_set_read_ahead()?
* the ssl_expr api is NOT THREAD SAFE. race conditions exist:
-in ssl_expr_comp() if SSLRequire is used in .htaccess
(ssl_expr_info is global)
-is ssl_expr_eval() if there is an error
(ssl_expr_error is global)
* SSLRequire directive (parsing of) leaks memory
* Diffie-Hellman-Parameters for temporary keys are hardcoded in
ssl_engine_dh.c, while the comment in ssl_engine_kernel.c says:
"it is suggested that keys be changed daily or every 500
transactions, and more often if possible."
* ssl_var_lookup could be rewritten to be MUCH faster
* CRL callback should be pluggable
* session cache store should be pluggable
* init functions should return status code rather than ssl_die()
* ssl_engine_pphrase.c needs to be reworked so it is generic enough
to also decrypt proxy keys
* the shmcb code should just align its memory segment rather than
jumping through all the "safe" memcpy and memset hoops
Experimental modules should eventually be be promoted to fully supported
status or removed from the repository entirely (ie, the 'experiment'
failed). This section tracks what needs to happen to get the modules
promoted to fully supported status.

cacheing the response w/o header "field_name"

status (num of entries, cache object properties, etc.).
mod_status could be extended to query optional hooks defined
by modules for the purpose of reporting module status.
mod_cache (et. al.) could define optional hooks that are called
to collect status. Status should be queryable by

Status: Cannot accept password-as-arg, we should prompt the

Other bugs that need fixing:
* ap_discard_request should be converted to use the bucket API
directly rather than waste cycles copying buffers with the old API.
* MaxRequestsPerChild measures connections, not requests.
Until someone has a better way, we'll probably just rename it
* Regex containers don't work in an intutive way
Status: No one has come up with an efficient way to fix this
behavior. Dean has suggested getting rid of regex containers
OtherBill suggests: We at least seem to agree on eliminating
the <Container ~ foo> forms, and using only
<ContainerMatch foo> semantics.
* SIGSEGV on Linux (glibc 2.1.2) isn't caught properly by a
sigwaiting thread. We need to work around this, perhaps unless
there is hope soon for a fixed glibc.
* orig_ct in the byterange/multipart handling may not be
needed. Apache 1.3 just never stashed "multipart" into
r->content_type. We should probably follow suit since the
byterange stuff doesn't want the rest of the code to see the
multipart content-type; the other code should still think it is
dealing with the <orig_ct> stuff.
