9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe wsanchez agrees: this may be a change in behavior, but isn't
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe clearly wrong, and even if so, it doesn't seem like a
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe showstopper.

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe stas replies: because it requires a rewrite of the filters stack
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe implementation (you have suggested that) and once 2.2 is
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe released you can't do that anymore.

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Filter stacks and subrequests, redirects and fast redirects.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe There's at least one PR that suffers from the current unclean behaviour
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe (which lets the server send garbage): PR 17629
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe nd says: Every subrequest should get its own filter stack with the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe subreq_core filter as bottom-most. That filter does two things:
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe - swallow EOS buckets
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe - redirect the data stream to the upper request's (rr->main)
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe filter chain directly after the subrequest's starting
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Once we have a clean solution, we can try to optimize
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe it, so that the server won't be slow down too much.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * RFC 2616 violations.

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe jerenkrantz says: need to decide how many we need to backport and/or
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe if these rise to showstopper status.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe wrowe suggests: it would be nice to see "MUST" v.s. "SHOULD" v.s. "MAY"
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe out of this list, without reviewing them individually.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * There is a bug in how we sort some hooks, at least the pre-config
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe hook. The first time we call the hooks, they are in the correct
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe order, but the second time, we don't sort them correctly. Currently,
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe the modules/http/config.m4 file has been renamed to
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe modules/http/config2.m4 to work around this problem, it should moved
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe back when this is fixed.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe OtherBill offers that this is a SERIOUS problem. We do not sort
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe correctly by the ordering arguments passed to the register hook
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe functions. This was proven when I reordered the open_logs hook
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe to attempt to open the error logs prior to the access logs. Possibly
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe the entire sorting code needs to be refactored.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * pipes deadlock on all platforms with limited pipe buffers (e.g. both
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Linux and Win32, as opposed to only Win32 on 1.3). The right solution
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe is either GStein's proposal for a "CGI Brigade", or OtherBill's proposal
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe for "Poll Buckets" for "Polling Filter Chains". Or maybe both :-)
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * All handlers should always send content down even if r->header_only
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe is set. If not, it means that the HEAD requests don't generate the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe same headers as a GET which is wrong.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * exec cmd and suexec arg-passing enhancements

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * The 2.0.36 worker MPM graceless shutdown changes work but are
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe a bit clunky on some platforms; eg, on Linux, the loop to
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe join each worker thread seems to hang, and the parent ends up
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe killing off the child with SIGKILL. But at least it shuts down.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe chrisd: Has this been fixed by the changes for PR 38737?
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * --enable-mods-shared="foo1 foo2" is busted on Darwin. Pier
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe posted a patch (Message-ID: <B8DBBE8D.575A%pier@betaversion.org>).
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * We do not properly substitute the prefix-variables in the configuration
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe scripts or generated-configs. (i.e. if sysconfdir is etc,
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe httpd-std.conf points to conf.)
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * If any request gets through ap_process_request_internal() and is
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe scheduled to be served by the core handler, without a flag that this
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe r->filename was tested by dir/file_walk, we need to 500 at the very
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe end of the ap_process_request_internal() processing so sub_req-esters
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe know this request cannot be run. This provides authors of older
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe modules better compatibility, while still improving the security and
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe robustness of 2.0.

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe [Deleted comments regarding the ap_run_handler phase, as irrelevant
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe as BillS points out that "common case will be caught in
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe default_handler already (with the r->finfo.filetype == 0 check)"
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe and the issue is detecting this -before- we try to run the req.]
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe gregames says: can this happen somehow without a broken module
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe being involved? If not, why waste cycles trying to defend against
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe potential broken modules? It seems futile.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe wrowe counters: no, it shouldn't happen unless the module is broken.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe But the right answer is to fail the request up-front in dir/file
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe walk if the path was entirely invalid; and we can't do that either
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe UNTIL 2.1 or we break modules that haven't hooked map_to_storage.

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe API issue but simply an extra trip through the brigade.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Try to get libtool inter-library dependency code working on AIX.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Justin says: If we get it working on AIX, we can enable this
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe on all platforms and clean up our build system somewhat.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Jeff says: I thought I tested a patch for you sometime in
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe January that you were going to commit within a few days.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Handling of %2f in URIs. Currently both 1.3 and 2.0
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe completely disallow %2f in the request URI path (see
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe ap_unescape_url() in util.c). It's permitted and passed
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe through in the query string, however. Roy says the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe original reason for disallowing it, from five years ago,
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe was to protect CGI scripts that applied PATH_INFO to
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe a filesystem location and which might be tricked by
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe ..%2f..%2f(...). We *should* allow path-info of the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Since we've revamped a lot of our processing of path
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe segments, it would be nice to allow this, or at least
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe allow it conditionally with a directive.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe OtherBill adds that %2f as the SECOND character of a multibyte
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe sequence causes the request to fail! This happens notably in
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe the ja-jis encoding.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * There is increasing demand from module writers for an API
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe that will allow them to control the server � la apachectl.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Reasons include sole-function servers that need to die if
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe an external dependency (e.g., a database) fails, et cetera.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Perhaps something in the (ever more abused) scoreboard?
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe On the other hand, we already have a pipe that goes between parent
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe and child for graceful shutdown events, along with an API that
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe can be used to send a message down that pipe. In threaded MPMs,
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe it is easy enough to make that one pipe be used for graceful
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe and graceless events, and it is also easy to open that pipe
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe to both parent and child for writing. Then we just need to
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe figure out how to do graceless on non-threaded MPMs.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Allow the DocumentRoot directive within <Location > scopes? This
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe allows the beloved (crusty) Alias /foo/ /somepath/foo/ followed
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe by a <Directory /somepath/foo> to become simply
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe <Location /foo/> DocumentRoot /somefile/foo (IMHO a bit more legible
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe and in-your-face.) DocumentRoot unset would be accepted [and would
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe not permit content to be served, only virtual resources such as
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe server-info or server-status.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe This proposed change would _not_ depricate Alias.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe striker: See the thread starting with Message-ID:

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Win32: Rotatelogs sometimes is not terminated when Apache
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe goes down hard. FirstBill was looking at possibly tracking the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe child's-child processes in the parent process.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe stoddard: Shared scoreboard might offer a good way for the parent
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe to keep track of 'other child' processes and whack them if the child
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Other thoughts on walking the process chain using the NT kernel
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe have also been proposed on APR.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Eliminate unnecessary creation of pipes in mod_cgid
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Combine log_child and piped_log_spawn. Clean up http_log.c.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Common logging API.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Platforms that do not support fork (primarily Win32 and AS/400)
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Architect start-up code that avoids initializing all the modules
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe in the parent process on platforms that do not support fork.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * There are still a number of places in the code where we are
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe losing error status (i.e. throwing away the error returned by a
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe system call and replacing it with a generic error code)
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Mass vhosting version of suEXEC.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * All DBMs suffer from confusion in support/dbmmanage (perl script) since
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe the dbmmanage employs the first-matched dbm format. This is not
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe necessarily the library that Apache was built with. Aught to
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe rewrite dbmmanage upon installation to bin/ with the proper library
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe for predictable mod_auth_dbm administration.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Questions; htdbm exists, time to kill dbmmanage, or does it remain
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe useful as a perl dbm management example? If we keep it,
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe do we address the issue above?
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Integrate mod_dav.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Some additional items remaining:
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe - case_preserved_filename stuff
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe (use the new canonical name stuff?)
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe - find a new home for ap_text(_header)
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe - is it possible to remove the DAV: namespace stuff from util_xml?
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe are a bit wonky. The function should probably be exposed as a utility
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe function (such as ap_translate_url2fs() or ap_validate_fs_url() or
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe something). Another approach would be a new hook phase after
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe "translate" which would allow the module to munge what the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe translation has decided to do.

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Scoreboard structures could be changed in the future such that

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe some systems. Cliff posted a patch to deal with this issue but
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe later recanted. See this message to dev@apr.apache.org:

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe thommay: this doesn't fix all the problems with apxs and out of

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * mod_cache: Resolve issue of how to cache page fragements (or perhaps
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe -if- we want to cache page fragements). Today, mod_cache/mod_mem_cache
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe will cache #include 'virtual' requests (but not #include 'file'
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe requests). This was accomplished by making CACHE_IN a
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe CONTENT_SET-1 filter to force it to run before the SUBREQ_CORE
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe filter. But now responses cannot be cached that include the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe effects of having been run through CONTENT_SET filters
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe (mod_deflate, mod_expires, etc). We could rerun all the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe CONTENT_SET filters on the cached response, but this will not
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe work in all cases. For example, mod_expires relies on installing
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe the EXPIRATION filter during fixups. Contents served out of
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe mod_cache (out of the quick_handler) bypass -all- the request
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe line server hooks (Ryan really hated this. It is great for
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe performance, but bad because of the complications listed above).
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * mod_mem_cache: Consider adding a RevalidateTimeout directive to
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe specify time at which local cached content is to be revalidated
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe (ie, underlying file stat'ed to see if it has changed).
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * mod_cache: CacheEnable/CacheDisable should accept regular expressions.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe jerenkrantz says: Too slow. Get regexs away from speedy caches by
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe default. Introduce a new CacheEnableRegex if you want.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * mod_mem_cache/mod_disk_cache: Need to be able to query cache
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe status (num of entries, cache object properties, etc.).
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe mod_status could be extended to query optional hooks defined
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe by modules for the purpose of reporting module status.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe mod_cache (et. al.) could define optional hooks that are called
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe to collect status. Status should be queryable by
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe HTTP or SNMP?
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe jerenkrantz says: Yawn. Who cares.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * MaxRequestsPerChild measures connections, not requests.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Until someone has a better way, we'll probably just rename it
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe "MaxConnectionsPerChild".
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * Regex containers don't work in an intutive way
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe Status: No one has come up with an efficient way to fix this
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe behavior. Dean has suggested getting rid of regex containers
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe completely.
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe OtherBill suggests: We at least seem to agree on eliminating

9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe * orig_ct in the byterange/multipart handling may not be
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe needed. Apache 1.3 just never stashed "multipart" into
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe r->content_type. We should probably follow suit since the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe byterange stuff doesn't want the rest of the code to see the
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe multipart content-type; the other code should still think it is
9e86ff266f053757dd96dab7cf4bc53aaaaa583ewrowe dealing with the <orig_ct> stuff.
