509622419be000045d461ef38fb97df778fdf81djailletc * ap_cache_hex2msec() and ap_cache_msec2hex() are completely
0b9de55d178312ec929dbe417dd61199b269991djailletc hosed. They do not handle apr_time_t (64 bit ints) properly.
0b9de55d178312ec929dbe417dd61199b269991djailletc
0b9de55d178312ec929dbe417dd61199b269991djailletc * If any request gets through ap_process_request_internal() and is
0b9de55d178312ec929dbe417dd61199b269991djailletc scheduled to be served by the core handler, without a flag that this
74e7f6c55fd67b10cb400b3f6d1dc718a303d944minfrin r->filename was tested by dir/file_walk, we need to 500 at the very
74e7f6c55fd67b10cb400b3f6d1dc718a303d944minfrin end of the ap_process_request_internal() processing so sub_req-esters
74e7f6c55fd67b10cb400b3f6d1dc718a303d944minfrin know this request cannot be run. This provides authors of older
74e7f6c55fd67b10cb400b3f6d1dc718a303d944minfrin modules better compatibility, while still improving the security and

63921358ef93fcb41bc71d9894221ba3d7fbb87bminfrin and the issue is detecting this -before- we try to run the req.]

6d601599d3d65df0410eae6e573e75b2dbfb1fb4minfrin gregames says: can this happen somehow without a broken module
6d601599d3d65df0410eae6e573e75b2dbfb1fb4minfrin being involved? If not, why waste cycles trying to defend against
6d601599d3d65df0410eae6e573e75b2dbfb1fb4minfrin potential broken modules? It seems futile.
6d601599d3d65df0410eae6e573e75b2dbfb1fb4minfrin wrowe counters: no, it shouldn't happen unless the module is broken.
4c02bab56a528a180bbe394d8b6e6fd9c1a3ac1esf But the right answer is to fail the request up-front in dir/file
4c02bab56a528a180bbe394d8b6e6fd9c1a3ac1esf walk if the path was entirely invalid; and we can't do that either
4c02bab56a528a180bbe394d8b6e6fd9c1a3ac1esf or we break modules that are unwilling to hook map_to_storage.

ef82e8fa164e0a1f8b813f7deb6b7ead96018c94niq * With AP_MODE_EXHAUSTIVE in the core, it is finally clear to me
26c5829347f6a355c00f1ba0301d575056b69536niq how the Perchild MPM should be re-written. It hasn't worked
ef82e8fa164e0a1f8b813f7deb6b7ead96018c94niq correctly since filters were added because it wasn't possible to
ef82e8fa164e0a1f8b813f7deb6b7ead96018c94niq get the content that had already been written and the socket at
ef82e8fa164e0a1f8b813f7deb6b7ead96018c94niq the same time. This mode lets us do that, so the MPM can be

79c5787b92ac5f0e1cc82393816c77a006399316trawick completely disallow %2f in the request URI path (see
79c5787b92ac5f0e1cc82393816c77a006399316trawick ap_unescape_url() in util.c). It's permitted and passed
79c5787b92ac5f0e1cc82393816c77a006399316trawick through in the query string, however. Roy says the
7b395e4e878c28a4784919cfd2e704ddd14a3390jorton original reason for disallowing it, from five years ago,
7b395e4e878c28a4784919cfd2e704ddd14a3390jorton was to protect CGI scripts that applied PATH_INFO to
7b395e4e878c28a4784919cfd2e704ddd14a3390jorton a filesystem location and which might be tricked by
7b395e4e878c28a4784919cfd2e704ddd14a3390jorton ..%2f..%2f(...). We *should* allow path-info of the
536e48c08d674acac5d44929318f2ad928edc361jorton form 'http://foo.com/index.cgi/path/to/path%2finfo'.
536e48c08d674acac5d44929318f2ad928edc361jorton Since we've revamped a lot of our processing of path
e81785da447b469da66f218b3f0244aab507958djorton segments, it would be nice to allow this, or at least
e81785da447b469da66f218b3f0244aab507958djorton allow it conditionally with a directive.

3e4e54d4e3fc0123c63d57aa84ac7ad7a8c73ff8jorton if you only have one worker process with many threads. Add
53e9b27aba029b18be814df40bcf6f0428771d1efuankg a second worker process and the accept lock seems to be
53e9b27aba029b18be814df40bcf6f0428771d1efuankg lost. This might be an APR issue with how it deals with
53e9b27aba029b18be814df40bcf6f0428771d1efuankg the child_init hook (i.e. the fcntl lock needs to be resynced).

ca61ccd0c306c2c72df153688ba1b49f3eceed80sf Justin says: So, FreeBSD-CURRENT and Cywin have the same
6bb524f1895f30265a1431afc460977d391cb36bsf problem. Yum. If another platform has this
e6dd71992459d05a676b98b7963423dc5dc1e24aminfrin with worker, this becomes a showstopper.
e6dd71992459d05a676b98b7963423dc5dc1e24aminfrin Aaron says: I spent some time disecting this and have come to
e6dd71992459d05a676b98b7963423dc5dc1e24aminfrin the conclusion that it is not a problem in the worker MPM
e6dd71992459d05a676b98b7963423dc5dc1e24aminfrin (or at least, it is not isolated to a problem in worker).
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin I'll list some of the problems I'm seeing in case someone
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin else wants to pick up where I've left off:
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin - Delivery of just about any signal to one of the child
23f1535d6a60817d2846bac0aea230ea475d7dccminfrin processes will send it into an infinite loop as well.
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung - Even though the parent is spinning out of control,
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung at first the child or children will appear to work
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung properly. At times it is possible to get it into a state,
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung however, where a request will hang until another concurrent
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung request "kicks" the first, at which point the second will
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung hang. My theory is that this has to do with the
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung pthread_cond_*() implementation in FreeBSD, but it's still
ec7520b24cd80d34d82bbcaca153cbb23cc04bc0rjung possible that it is in APR.

6249dfa569d3b4f1f539665b979a80c6e335d93etrawick Justin adds: Oh, FreeBSD threads are implemented entirely with
0827cb14e550f6f65018431c22c2c913631c8f25kbrand select()/poll()/longjmp(). Welcome to the nightmare.
6249dfa569d3b4f1f539665b979a80c6e335d93etrawick So, that means a ktrace output also has the thread
ae600ca541efc686b34f8b1f21bd3d0741d37674covener scheduling internals in it (since it is all the same to
6249dfa569d3b4f1f539665b979a80c6e335d93etrawick the kernel). Which makes it hard to distinguish between
cfa64348224b66dd1c9979b809406c4d15b1c137fielding our select() calls and their select() calls.
74499a117b3b2cd9666715a14f90c0e5d1a4ee8ajim *bangs head on wall repeatedly* But, some of the libc_r
cfa64348224b66dd1c9979b809406c4d15b1c137fielding files have a DBG_MSG #define. This is moderately helpful
74499a117b3b2cd9666715a14f90c0e5d1a4ee8ajim when used with -DNO_DETACH. The kernel scheduler isn't
cfa64348224b66dd1c9979b809406c4d15b1c137fielding waking up the threads on a select(). Yum. And, I bet
74499a117b3b2cd9666715a14f90c0e5d1a4ee8ajim those decrementing select calls have to do with the
cfa64348224b66dd1c9979b809406c4d15b1c137fielding scheduler. Time to brush up on our OS fundamentals.
74499a117b3b2cd9666715a14f90c0e5d1a4ee8ajim
cfa64348224b66dd1c9979b809406c4d15b1c137fielding * 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
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.
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:
The current porting state is summarized in modules/ssl/README. The
remaining work includes:
(1) stablizing/optimizing the SSL filter logic
(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.
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?
* 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:
- 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)
* 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:

Status:
Other bugs that need fixing:
* MaxRequestsPerChild measures connections, not requests.
Until someone has a better way, we'll probably just rename it
"MaxConnectionsPerChild".
* 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
completely.
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.

likely the one to break it :-)
