1177N/APlease consult the following STATUS files for information
244N/A * Runtime startup failures don't reliably set the exit status.
244N/A For instance, try listening to port 80 and starting as non-root;
244N/A server fails with make_sock and 'no listening sockets' errors
244N/A but exits with 0 status. Even with -DONE_PROCESS -DNO_DETACH.
244N/A Justin says: "Is this really a showstopper? Most people won't
244N/A be using -DNO_DETACH and will look at the error
244N/A * mod_rewrite's locks (win32) were broken by recent changes to the
244N/A apr_lock_t api (which we were deprecating in the first place, so
244N/A I'm far from certain why it changed.) It has to do with creating
244N/A the rewrite logs mutex. The solution is to find the brokenness in
244N/A apr_lock_t, but if it goes away, why waste the time?
244N/A * ap_directory_walk skips some per-dir config merge functions
244N/A if there is no "<Directory />" block in the configuration
244N/A Message-ID: <m3itbdiijq.fsf@rdu163-40-092.nc.rr.com>
244N/A * That is very unlikely, merges are additive. Much more likely,
244N/A the default SetOutputFilter default or merge is borked.
244N/A Unless it's the code that permits 'null' merges, per module.
244N/A Still, it's probably in SetOutputFilter's behavior.
244N/A o worker is also failing some of the 'cgi' subtests
244N/A Justin says: "Worker should be fine and passes httpd-test here."
244N/A * If any request gets to the core handler, without a flag that this
244N/A end of the ap_process_request_internal() processing. This provides
244N/A authors of older modules better compatibility, while still improving
244N/A the security and robustness of 2.0.
244N/A Status: still need to decide where this goes, OtherBill comments...
244N/A Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
244N/A we need to look at halting this in the 'default handler' case,
244N/A and that implies pushing the 'handler election' into the request
244N/A internal processing phase from the run request phase.
244N/A * There is a bug in how we sort some hooks, at least the pre-config
244N/A hook. The first time we call the hooks, they are in the correct
244N/A order, but the second time, we don't sort them correctly. Currently,
796N/A back when this is fixed. rbb
796N/A Justin says: "Is this really a showstopper? This has been here
796N/A forever. What's wrong? Does this have to do with
244N/A administrator to order filters, beyond the order of filename (mime)
244N/A filename extensions. At minimum, some sort of +-[0-10] syntax seems
244N/A like the quickest fix for a 2.0 gold release.
244N/A Justin says: "Could we delay this for a point release or 2.1?"
244N/A * Convert all instances of the old apr_lock_t type to the new
244N/A types (once they are fully supported in APR).
244N/A Status: Aaron is working on converting INTRAPROCESS
244N/A to apr_thread_mutex_t types. Full replacements for
244N/A LOCKALL and CROSS_PROCESS are not yet complete on all
244N/A platforms, and should only be used in MPMs like worker
244N/A with limited OS exposure.
244N/A * A binbuild installation picks up the right libraries when
244N/A running apachectl because we set the appropriate environment
244N/A variable, but ab, htpasswd, etc. don't know how to pick up apr,
244N/A Message-ID: <20020116000226.GA15991@ebuilt.com>
244N/A Justin says: "You could always build all of the binaries
244N/A statically if you don't want to let libtool
244N/A handle it. At most, I don't consider this a
244N/A a release showstopper as it is a packaging issue."
244N/A Status: Aaron volunteers: I'll commit a patch to allow all
244N/A the support binaries to be built statically against
244N/ARELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
244N/A * If the parent process dies, should the remaining child processes
244N/A "gracefully" self-terminate.
244N/A Message-ID: <3C58232C.FE91F19F@Golux.Com>
244N/A * Make some modifications to the scoreboard creation routines,
244N/A prefer anonymous shared memory, and allow a configuration
244N/A directive to override the defaults.

244N/A Status: Aaron volunteers
244N/A * Get perchild to work on platforms other than Linux. This
244N/A descriptors between vhost child groups. An API was proposed
244N/A Message-ID: <20020111115006.K1529@clove.org>
244N/A Vote: Is a non-portable perchild going to hold up a GA release?
244N/A * Modify the worker MPM so that it doesn't need to create and
244N/A destroy a pool for each request--possibly by adopting a
244N/A ptrans pool (like the prefork MPM) and the workers take
244N/A reduce context-switching
244N/A * CGI single-byte reads
244N/A BrianP suggests that this is caused by the ap_scan_script_header_err()
244N/A routine, which will do single-byte reads until it finds the end
244N/A of the header, at which point it constructs a pipe-bucket (buffered)
244N/A Message-ID: <3C36ADAF.60601@cnet.com>
244N/A * Try to get libtool inter-library dependency code working on AIX.
244N/A Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
244N/A Justin says: If we get it working on AIX, we can enable this
244N/A on all platforms and clean up our build system
244N/A * Handling of %2f in URIs. Currently both 1.3 and 2.0
244N/A completely disallow %2f in the request URI path (see
244N/A ap_unescape_url() in
util.c). It's permitted and passed
244N/A through in the query string, however. Roy says the
244N/A original reason for disallowing it, from five years ago,
244N/A was to protect CGI scripts that applied PATH_INFO to
244N/A a filesystem location and which might be tricked by
244N/A ..%2f..%2f(...). We *should* allow path-info of the
244N/A Since we've revamped a lot of our processing of path
244N/A segments, it would be nice to allow this, or at least
244N/A allow it conditionally with a directive.
244N/A * FreeBSD, threads, and worker MPM. All seems to work fine
244N/A if you only have one worker process with many threads. Add
244N/A a second worker process and the accept lock seems to be
244N/A lost. This might be an APR issue with how it deals with
244N/A the child_init hook (
i.e. the fcntl lock needs to be resynced).
244N/A More examination and analysis is required.
244N/A Status: This has also been reported on Cygwin.
244N/A Message-ID: <3C2CC514.8EF3BED1@wapme-systems.de> (cygnus)
244N/A Justin says: So, FreeBSD-CURRENT and Cywin have the same
244N/A problem. Yum. If another platform has this
244N/A with worker, this becomes a showstopper.
244N/A Aaron says: I spent some time disecting this and have come to
244N/A the conclusion that it is not a problem in the worker MPM
244N/A (or at least, it is not isolated to a problem in worker).
244N/A I'll list some of the problems I'm seeing in case someone
244N/A else wants to pick up where I've left off:
244N/A - Delivery of just about any signal to one of the child
244N/A processes will send it into an infinite loop as well.
244N/A - Even though the parent is spinning out of control,
244N/A at first the child or children will appear to work
244N/A properly. At times it is possible to get it into a state,
244N/A however, where a request will hang until another concurrent
244N/A request "kicks" the first, at which point the second will
244N/A hang. My theory is that this has to do with the
244N/A pthread_cond_*() implementation in FreeBSD, but it's still
244N/A possible that it is in APR.
244N/A Justin adds: Oh, FreeBSD threads are implemented entirely with
244N/A select()/poll()/longjmp(). Welcome to the nightmare.
244N/A So, that means a ktrace output also has the thread
244N/A scheduling internals in it (since it is all the same to
244N/A the kernel). Which makes it hard to distinguish between
244N/A our select() calls and their select() calls.
244N/A *bangs head on wall repeatedly* But, some of the libc_r
244N/A files have a DBG_MSG #define. This is moderately helpful
244N/A when used with -DNO_DETACH. The kernel scheduler isn't
244N/A waking up the threads on a select(). Yum. And, I bet
244N/A those decrementing select calls have to do with the
244N/A scheduler. Time to brush up on our OS fundamentals.
244N/A * There is increasing demand from module writers for an API
244N/A that will allow them to control the server � la apachectl.
244N/A Reasons include sole-function servers that need to die if
244N/A an external dependency (
e.g., a database) fails, et cetera.
244N/A Perhaps something in the (ever more abused) scoreboard?
244N/A rbb: I don't believe the scoreboard is the correct mechanism
244N/A for this. We already have a pipe that goes between parent
244N/A and child for graceful shutdown events, along with an API that
244N/A can be used to send a message down that pipe. In threaded MPMs,
244N/A it is easy enough to make that one pipe be used for graceful
244N/A and graceless events, and it is also easy to open that pipe
244N/A to both parent and child for writing. Then we just need to figure
244N/A out how to do graceless on non-threaded MPMs.
244N/A * revamp the input filter behavior, per discussions since
244N/A February (and especially at the hackathon last
244N/A April). Specifically, ap_get_brigade will return a brigade with
244N/A *up to* a specific number of bytes, or a "line" of data. The
244N/A read may be blocking or nonblocking. ap_getline() will be
244N/A refactored into apr_brigade_getline(), and then DECHUNK can use
244N/A f->next (ap_getline will always read "top of input stack"). Also
244N/A fix the bug where request body content will end up closing the
244N/A connection (buggering up persistent conns).
244N/A Status: Justin is working on this as fast as he can.
244N/A The core input filters, HTTP-related filters, mod_ssl, and
244N/A mod_proxy are switched to the new logic.
244N/A However, ap_getline() still needs to be refactored out. But,
244N/A there's a problem there: ap_getline() peeks ahead for MIME
244N/A continuation (first character on line is space or \t) and
244N/A stores unused data in core_request_config which violates the
244N/A abstraction. That's cheating. So, we may not be able to
244N/A implement this without setting some data aside (yuck!).
244N/A I believe this is OtherBill's main complaint with the current
244N/A AIUI (correct me if I'm wrong!), OtherBill believes we
244N/A should have a pushback option so that we can return unread
244N/A data - this would solve this case. However, my question to
244N/A him is how do we handle stuff like mod_ssl - we can't "unread"
244N/A data. So, do we have two brigades for each filter? An in
244N/A brigade and a returned brigade? That seems messy. To
244N/A everyone else, can we refactor ap_getline() without pushback
244N/A - socket bucket and core input filter changes. see end of

244N/A * Allow the DocumentRoot directive within <Location > scopes? This
244N/A and in-your-face.) DocumentRoot unset would be accepted [and would
244N/A not permit content to be served, only virtual resources such as
244N/A server-info or server-status.
509N/A This proposed change would _not_ depricate Alias.
244N/A * Win32: Rotatelogs sometimes is not terminated when Apache
244N/A goes down hard. FirstBill was looking at possibly tracking the
244N/A child's-child processes in the parent process.
244N/A OtherBill asks, wasn't this fixed?
244N/A OtherBill asks again, what is the status?
244N/A * Win32: Add a simple hold console open patch (wait for close or
244N/A the ESC key, with a nice message) if the server died a bad
244N/A death (non-zero exit code) in console mode.
244N/A Resolution: bring forward same ugly hacks from 1.3.13-.20
244N/A * Port of mod_ssl to Apache 2.0:
244N/A remaining work includes:
244N/A (2) Enabling the various SSL caching mechanisms (shmcb, shmht)
244N/A (3) Enabling SSL extentions
244N/A (4) Trying to seperate the https filter logic from mod_ssl -
244N/A This is to facilitate other modules that wish to use the https
244N/A filter or the mod_ssl logic or both as required.
244N/A Justin: mod_ssl filter logic is redone, so that should be fine.
244N/A Madhu has submitted a patch for SSL caching - however, I
244N/A am -0 on that patch as I *think* we could implement the
244N/A shared memory another way that is much cleaner (
i.e. 244N/A treat shmem directly as a dbm via APR routines). Justin
244N/A also thinks that the https filter logic may be sufficiently
244N/A decoupled now, but isn't really sure.
244N/A * Performance & Debug: Eliminate most (and perhaps all) of the
244N/A light weight memory management functions that allow freeing
244N/A memory (putting it back into a memory pool) when it is no
244N/A longer needed. Enabling simple debugging features like guard
244N/A bands, double free detection, etc. would be cool but certainly
244N/A not a hard requirement.
244N/A Status: Cliff started to implement this using SMS as has
244N/A been discussed at length for months, but since
244N/A SMS is not being used anywhere else in the server,
244N/A several people expressed the opinion that we should
244N/A get rid of it entirely, meaning that the buckets
244N/A need their own memory management (free list) functions.
244N/A Cliff will implement that this weekend so we at least
244N/A * Eliminate unnecessary creation of pipes in mod_cgid
244N/A * the autoconf setup should be fixed to default to using the
244N/A in a layout should be overridable on the command line. Plus,
244N/A what we do right now just doesn't seem to fully fit into how autoconf
244N/A works, eg. AC_PREFIX_DEFAULT issues.
244N/A Message-ID: <Pine.BSF.4.20.0104031557420.20876-100000@alive.znep.com>
244N/A * Document mod_file_cache.
244N/A * Platforms that do not support fork (primarily Win32 and AS/400)
244N/A Architect start-up code that avoids initializing all the modules
244N/A in the parent process on platforms that do not support fork.
244N/A would eliminate some code in the Win32 branch that essentially
244N/A duplicates what is in APR.
244N/A * There are still a number of places in the code where we are
244N/A losing error status (
i.e. throwing away the error returned by a
244N/A system call and replacing it with a generic error code)
244N/A * Mass vhosting version of suEXEC.
244N/A the dbmmanage employs the first-matched dbm format. This is not
244N/A necessarily the library that Apache was built with. Aught to
244N/A rewrite dbmmanage upon installation to bin/ with the proper library
244N/A for predictable mod_auth_dbm administration.
244N/A Questions; htdbm exists, time to kill dbmmanage, or does it remain
244N/A useful as a perl dbm management example? If we keep it,
244N/A do we address the issue above?
244N/A * use apu_dbm in mod_auth_dbm
244N/A Status: Greg +1 (low-priority volunteer)
244N/A Justin says: "Seems like this is already there, so should we just
244N/A remove the other DBM code in that file? If you want
244N/A to use gdbm, or dbm, etc, you should tell apr-util."
244N/A Will says: "bs - I may choose the fastest - most efficient native
244N/A dbm implementation, for shared proc caches, ssl session
244N/A caching, etc, but that has nothing to do with maintaining
244N/A a userlist via dbm, which has to remain readable between
244N/A for apr-util would let us do this with just apr, though."
244N/A Ian says: "multi-dbm is in, but it still has ndbm support hardcoded
244N/A is this still required? isn't ndbm supported via gdbm?"
244N/A Some additional items remaining:
244N/A - case_preserved_filename stuff
244N/A (use the new canonical name stuff?)
244N/A - find a new home for ap_text(_header)
244N/A - is it possible to remove the DAV: namespace stuff from util_xml?
244N/A * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
244N/A are a bit wonky. The function should probably be exposed as a utility
244N/A function (such as ap_translate_url2fs() or ap_validate_fs_url() or
244N/A something). Another approach would be a new hook phase after
244N/A "translate" which would allow the module to munge what the
244N/A translation has decided to do.
244N/A Status: Greg +1 (volunteers), Ryan +1
244N/A calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and

244N/A * read the config tree just once, and process N times (as necessary)
244N/A * (possibly) use UUIDs in mod_unique_id
and/or mod_usertrack

244N/A into a VirtualHost container) to 2.0.

* Win32: Get Apache working on Windows 95/98. The following work
(at least) needs to be done:
- winnt MPM: Fix 95/98 code paths in the winnt MPM. There is some NT
specific code that is still not in NT only code paths
- IOL binds to APR sendfile, implemented with TransmitFile, which
is not available on 95/98.
- 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
* Make the worker MPM the default MPM for threaded Unix boxes.
-0: Aaron (premature decision, needs more discussion), Lars
-0: Cliff (I think the default config should be the safest possible)
* Fix the worker MPM to use POD to kill child processes instead
of ap_os_killpg, regardless of how they should die. (Ryan Bloom)

[PATCH] install as win32 service with domain account
Status: Cannot accept password-as-arg, we should prompt the
user when -k install/-k config with a user argument.
AllowOverride should have a 'CheckNone' and 'AllowNone' argument
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
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.
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.
Status: Greg volunteers to investigate (esp. since he was most
likely the one to break it :-)
Other features that need writing:
* Finish infrastructure in core for async MPMs
* TODO in source -- just do an egrep on "TODO" and see what's there
* Jon Travis's <jtravis@covalent.net> patch to deal with thread-safe
issues with inet_ntoa. See message <20001201163220.A12827@covalent.net>
Status: This is being set aside until the IPv6 work is finished
so that we know exactly what is required.

htpasswd actions due to a full /tmp volume (other programs may have
* Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve
Status: These were written for 1.3, and are awaiting a port to
