d208bda4a893cc81ed5d3ed1cdd7d706e012bd42stoddard There are a couple of problems that need to be resolved
d208bda4a893cc81ed5d3ed1cdd7d706e012bd42stoddard before this module is moved out of experimental.
d208bda4a893cc81ed5d3ed1cdd7d706e012bd42stoddard 1) We need to at least review and comment on the RFC violations
d208bda4a893cc81ed5d3ed1cdd7d706e012bd42stoddard 2) Resolve issue of how to cache page fragements (or perhaps -if- we
d208bda4a893cc81ed5d3ed1cdd7d706e012bd42stoddard want to cache page fragements). Today, mod_cache/mod_mem_cache
d208bda4a893cc81ed5d3ed1cdd7d706e012bd42stoddard will cache #include 'virtual' requests (but not #include 'file'
75960f20f88dad6bc67892c711c429946063d133stoddard requests). This was accomplished by making CACHE_IN a
75960f20f88dad6bc67892c711c429946063d133stoddard CONTENT_SET-1 filter to force it to run before the SUBREQ_CORE
75960f20f88dad6bc67892c711c429946063d133stoddard filter. But now responses cannot be cached that include the
75960f20f88dad6bc67892c711c429946063d133stoddard effects of having been run through CONTENT_SET filters
75960f20f88dad6bc67892c711c429946063d133stoddard (mod_deflate, mod_expires, etc). We could rerun all the
75960f20f88dad6bc67892c711c429946063d133stoddard CONTENT_SET filters on the cached response, but this will not
75960f20f88dad6bc67892c711c429946063d133stoddard work in all cases. For example, mod_expires relies on installing
75960f20f88dad6bc67892c711c429946063d133stoddard the EXPIRATION filter during fixups. Contents served out of
75960f20f88dad6bc67892c711c429946063d133stoddard mod_cache (out of the quick_handler) bypass -all- the request
75960f20f88dad6bc67892c711c429946063d133stoddard line server hooks (Ryan really hated this. It is great for
75960f20f88dad6bc67892c711c429946063d133stoddard performance, but bad because of the complications listed above).

2a6c49cfaef5979a5a06098f3ce987cd76769409manoj jerenkrantz: There are a slew of RFC compliance bugs filed in Bugzilla
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj for mod_cache (see 'RFC 2616 violations' below). I think
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj fixing them is a pre-requisite before it isn't experimental.

8de99b4c89d4ed4292a7dca42dd8a96b9a7c456fdgaudet doesn't make ANY sense at all.
8de99b4c89d4ed4292a7dca42dd8a96b9a7c456fdgaudet +1: ianh - medium/big sites don't use 'standard config' anyway, as it
8de99b4c89d4ed4292a7dca42dd8a96b9a7c456fdgaudet usually needs major customizations

70f6f32765cfaadd6da8de6f0fea97ddd72d8fadmanoj There's at least one PR that suffers from the current unclean behaviour
70f6f32765cfaadd6da8de6f0fea97ddd72d8fadmanoj (which lets the server send garbage): PR 17629
70f6f32765cfaadd6da8de6f0fea97ddd72d8fadmanoj nd says: Every subrequest should get its own filter stack with the
56ca30c968906053ae61acb218420667bb58d996rbb subreq_core filter as bottom-most. That filter does two things:
0bff2f28ef945280c17099c142126178a78e1e54manoj - swallow EOS buckets
0bff2f28ef945280c17099c142126178a78e1e54manoj - redirect the data stream to the upper request's (rr->main)
0bff2f28ef945280c17099c142126178a78e1e54manoj filter chain directly after the subrequest's starting

3304cbd819df02e7548e9338dc0afa8d3ba29358manoj order, but the second time, we don't sort them correctly. Currently,
f03d292915be9977eaf74e9be7b0404aec226f84manoj the modules/http/config.m4 file has been renamed to
f03d292915be9977eaf74e9be7b0404aec226f84manoj modules/http/config2.m4 to work around this problem, it should moved

aa1faea36e4ae357bc603a2337b6adc54f5daec1manoj OtherBill offers that this is a SERIOUS problem. We do not sort

d6b3cb141f0667101c1bca883ad15b383402c93bfielding Update by Jeff 20020722: I got an account on HP 10.20. It looks
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj like some of the APR thread detection is screwed up. If we find
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj pthread.h but we can't compile the pthread test program we still
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj think we can use threads. For that reason, the patch I posted
40a5b7189dbbb28e107bf008ee625f2f0142c2ccdgaudet to the PR won't work as-is since a failed compile of the test
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj program means nothing.

f6a6245816cd866361da8c576b1f47c7a54b6610fanf a bit clunky on some platforms; eg, on Linux, the loop to
f6a6245816cd866361da8c576b1f47c7a54b6610fanf join each worker thread seems to hang, and the parent ends up
f6a6245816cd866361da8c576b1f47c7a54b6610fanf killing off the child with SIGKILL. But at least it shuts down.

2a6c49cfaef5979a5a06098f3ce987cd76769409manoj gregames says: can this happen somehow without a broken module
2a6c49cfaef5979a5a06098f3ce987cd76769409manoj being involved? If not, why waste cycles trying to defend against
d6b3cb141f0667101c1bca883ad15b383402c93bfielding potential broken modules? It seems futile.
d6b3cb141f0667101c1bca883ad15b383402c93bfielding wrowe counters: no, it shouldn't happen unless the module is broken.
d6b3cb141f0667101c1bca883ad15b383402c93bfielding 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
fixed.
* Can a static httpd be built reliably?
Message-ID: <20020207142751.T31582@clove.org>
* [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: <Pine.LNX.4.33.0201202232430.318-100000@deepthought.cs.virginia.edu>
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:
Message-ID: <20020111115006.K1529@clove.org>
* 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.
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.
* 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.
FreeBSD 5.2-RC is a confirmed fix w/either libkse or libthr.
[libc_r, still the default, does not serve any pages w/worker;
so on FreeBSD 5.2, you must use libmap.conf (see man page).]
Work needs to be done to get APR to try to be knowledgable that
libkse/libthr are acceptable. Still not recommended for the
default since libc_r is still broken.
Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
* 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?
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.
* 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.
striker: See the thread starting with Message-ID:
JLEGKKNELMHCJPNMOKHOGEEJFBAA.striker@apache.org.
* 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.
* 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.
* 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)
* (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 dev@apr.apache.org:
Message-ID: <Pine.LNX.4.44.0203011354090.16457-200000@deepthought

* When sufficiently tested, the AllowEncodedSlashes/%2f patch
needs to be backported to 2.0 and 1.3.
* APXS either needs to be fixed completely for use when apr is out of tree,
or it should drop query mode altogether, and we just grow an
httpd-config or similar arrangement.
To quote a discussion in STATUS earlier:
thommay: this doesn't fix all the problems with apxs and out of
tree apr/apr-util, but it's a good start. There's still the
query cases; but I'm beginning to think that in these cases
the app should be querying ap{r,u}-config directly
gstein: agreed. apxs should deprecate the -q flag
TODO ISSUES REMAINING IN MOD_SSL:
* 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
WISH LIST
* mod_proxy performance: when mod_proxy is configured to do proxy
gateway (aka reverse proxy), it would be nice to be able to reuse
connections to the backend servers. Now, connections to the
backend servers are taken down when the corresponding frontend
connection is taken down.
* mod_proxy: Ability to run SSL over proxy gateway connections,
encrypting (or reencrypting) at the proxy.
* mod_proxy: Add capability of mod_proxy to load balance across
a farm of backend servers.
* mod_cache: Handle ESI tags.
EXPERIMENTAL MODULES:
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.
mod_cache/mod_mem_cache/mod_disk_cache:
* 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
* mod_mem_cache: Consider adding a RevalidateTimeout directive to
specify time at which local cached content is to be revalidated
(ie, underlying file stat'ed to see if it has changed).
* mod_cache: CacheEnable/CacheDisable should accept regular expressions.
* mod_cache: Fix dependency on ATOMIC operators. Need
APR_HAS_ATOMIC_* feature macros.
* mod_disk_cache: Implement garbage collection
* mod_mem_cache/mod_disk_cache: Need to be able to query cache
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
HTTP or SNMP?
* Enable mod_cache/mod_mem_cache/mod_disk_cache to handle
multiviews
* mod_mem_cache/mod_disk_cache: Complete implementing config
directives (mod_disk_cache: CacheExpiryCheck and GC directives
including CacheGc*, CacheSize, and, CacheTimeMargin)
(mod_mem_cache: MCacheMaxObjectCount) and
(mod_cache: CacheForceCompletion).

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
"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 :-)
