0N/A [Deleted comments regarding the ap_run_handler phase, as irrelevant
0N/A as BillS points out that "common case will be caught in
0N/A and the issue is detecting this -before- we try to run the req.]
0N/A gregames says: can this happen somehow without a broken module
0N/A being involved? If not, why waste cycles trying to defend against
0N/A 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
or we break modules that are unwilling to hook map_to_storage.
* Rewrite core_output_filter. It is nearly impossible to support
it with predictable results as it is implemented now.
* Convert all instances of the old apr_lock_t type to the new
Status: Aaron has converted all but the perchild MPM to
use the new lock API. Since perchild has been put
on the back burner, this is no longer a showstopper.
Aaron will patch perchild as soon as it becomes
* 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

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."

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,

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.

will require a portable mechanism to pass data and
file/socket descriptors between vhost child groups. An API was proposed

on all platforms and clean up our build system
Jeff says: I thought I tested a patch for you sometime in
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
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.
* Allow the DocumentRoot directive within <Location > scopes? This
<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.
Other thoughts on walking the process chain using the NT kernel
have also been proposed on APR.
* 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:
(2) Enabling SSL extentions
(3) 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.
* Eliminate unnecessary creation of pipes in mod_cgid
* Combine log_child and piped_log_spawn. Clean up
http_log.c. * 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.
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.
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?
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.
* 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.
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
* Fix the worker MPM to use POD to kill child processes instead
of ap_os_killpg, regardless of how they should die. (Ryan Bloom)
* mod_cache: handle cache_control: no_cache "field_name" to enable
cacheing the response w/o header "field_name"
See RFC2616 section 14.9.1
* 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 dev@apr.apache.org:

needed. Apache 1.3 just never stashed "multipart" into
