0N/APlease consult the following STATUS files for information
0N/ARELEASE SHOWSTOPPERS:
0N/A * If any request gets to the core handler, without a flag that this
0N/A end of the ap_process_request_internal() processing. This provides
0N/A authors of older modules better compatibility, while still improving
0N/A the security and robustness of 2.0.
0N/A Status: still need to decide where this goes, OtherBill comments...
0N/A Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
0N/A we need to look at halting this in the 'default handler' case,
0N/A and that implies pushing the 'handler election' into the request
0N/A internal processing phase from the run request phase.
0N/A * There is a bug in how we sort some hooks, at least the pre-config
0N/A hook. The first time we call the hooks, they are in the correct
0N/A order, but the second time, we don't sort them correctly. Currently,
0N/A back when this is fixed. rbb
0N/A administrator to order filters, beyond the order of filename (mime)
1460N/A filename extensions. At minimum, some sort of +-[0-10] syntax seems
1460N/A like the quickest fix for a 2.0 gold release.
1460N/A * mod_negotiation needs a new option or directive, something like
1460N/A ForceLanguagePriority, to fall back to the LanguagePriority
1460N/A directive instead of returning a "no acceptable variant" error.
0N/A Status: Bill has some code in his tree that accomplishes
0N/A this, and will commit it Friday after it's tested.
1460N/A * Fold mod_auth_db features back into mod_auth_dbm, and depricate it.
1460N/A This can't wait until we have a 2.0-gold release, if folks need
0N/A to move over to auth_dbm, we can't do that to them after 2.0 gold.
1460N/A Status: Ian says.. now that apr-util can handle multiple DBM types
0N/A we can probably deprecate it completly by adding a directive
0N/A 'AuthDBMType' to mod_auth_dbm.
1460N/A * Convert all instances of the old apr_lock_t type to the new
1460N/A types (once they are fully supported in APR).
0N/A Status: Aaron is working on converting INTRAPROCESS
1460N/A to apr_thread_mutex_t types. Full replacements for
1460N/A LOCKALL and CROSS_PROCESS are not yet complete on all
0N/A platforms, and should only be used in MPMs like worker
0N/A lines. Thus, stuff like ap_hook_error_log doesn't end up in
0N/A ap_hook_error_log (or other missing functions -- if there are
0N/A any) to segfault on AIX and can probably cause load or other
0N/A errors on some other platforms.
160N/ARELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
160N/A * There is increasing demand from module writers for an API
160N/A that will allow them to control the server � la apachectl.
160N/A Reasons include sole-function servers that need to die if
160N/A an external dependency (
e.g., a database) fails, et cetera.
160N/A Perhaps something in the (ever more abused) scoreboard?
160N/A rbb: I don't believe the scoreboard is the correct mechanism
160N/A for this. We already have a pipe that goes between parent
160N/A and child for graceful shutdown events, along with an API that
160N/A can be used to send a message down that pipe. In threaded MPMs,
160N/A it is easy enough to make that one pipe be used for graceful
160N/A and graceless events, and it is also easy to open that pipe
160N/A to both parent and child for writing. Then we just need to figure
160N/A out how to do graceless on non-threaded MPMs.
160N/A * revamp the input filter behavior, per discussions since
160N/A February (and especially at the hackathon last
0N/A April). Specifically, ap_get_brigade will return a brigade with
0N/A *up to* a specific number of bytes, or a "line" of data. The
0N/A read may be blocking or nonblocking. ap_getline() will be
0N/A refactored into apr_brigade_getline(), and then DECHUNK can use
0N/A f->next (ap_getline will always read "top of input stack"). Also
0N/A fix the bug where request body content will end up closing the
0N/A connection (buggering up persistent conns).
0N/A Status: Justin is working on this as fast as he can.
0N/A The core input filters, HTTP-related filters, mod_ssl, and
0N/A mod_proxy are switched to the new logic.
0N/A However, ap_getline() still needs to be refactored out. But,
0N/A there's a problem there: ap_getline() peeks ahead for MIME
0N/A continuation (first character on line is space or \t) and
0N/A stores unused data in core_request_config which violates the
0N/A abstraction. That's cheating. So, we may not be able to
0N/A implement this without setting some data aside (yuck!).
0N/A I believe this is OtherBill's main complaint with the current
0N/A AIUI (correct me if I'm wrong!), OtherBill believes we
0N/A should have a pushback option so that we can return unread
0N/A data - this would solve this case. However, my question to
0N/A him is how do we handle stuff like mod_ssl - we can't "unread"
0N/A data. So, do we have two brigades for each filter? An in
0N/A brigade and a returned brigade? That seems messy. To
0N/A everyone else, can we refactor ap_getline() without pushback
0N/A - socket bucket and core input filter changes. see end of
0N/A message ID (Feb 27): <20010227075326.S2297@lyra.org>

0N/A Message-ID: <021b01c14dee$09782af0$93c0b0d0@roweclan.net>
0N/A * Allow the DocumentRoot directive within <Location > scopes? This
0N/A and in-your-face.) DocumentRoot unset would be accepted [and would
0N/A not permit content to be served, only virtual resources such as
0N/A server-info or server-status.
0N/A This proposed change would _not_ depricate Alias.
0N/A * daedalus: mod_cgid and suexec have a problem co-existing. suexec
0N/A sees a null command string sometimes. The problem happens when
0N/A * Win32: Rotatelogs sometimes is not terminated when Apache
0N/A goes down hard. FirstBill was looking at possibly tracking the
0N/A child's-child processes in the parent process.
0N/A OtherBill asks, wasn't this fixed?
0N/A * Win32: Add a simple hold console open patch (wait for close or
0N/A the ESC key, with a nice message) if the server died a bad
0N/A death (non-zero exit code) in console mode.
0N/A Resolution: bring forward same ugly hacks from 1.3.13-.20
0N/A * Port of mod_ssl to Apache 2.0:
0N/A remaining work includes:
160N/A (2) Enabling the various SSL caching mechanisms (shmcb, shmht)
160N/A (3) Enabling SSL extentions
0N/A (4) Trying to seperate the https filter logic from mod_ssl -
0N/A This is to facilitate other modules that wish to use the https
0N/A filter or the mod_ssl logic or both as required.
0N/A Justin: mod_ssl filter logic is redone, so that should be fine.
0N/A Madhu has submitted a patch for SSL caching - however, I
0N/A am -0 on that patch as I *think* we could implement the
0N/A shared memory another way that is much cleaner (
i.e. 0N/A treat shmem directly as a dbm via APR routines). Justin
0N/A also thinks that the https filter logic may be sufficiently
0N/A decoupled now, but isn't really sure.
0N/A * Performance: Get the SINGLE_LISTEN_UNSERIALIZED_ACCEPT
0N/A optimization working in worker. prefork's new design for how
0N/A to notice data on the pod should be sufficient.
0N/A * Performance & Debug: Eliminate most (and perhaps all) of the
0N/A light weight memory management functions that allow freeing
0N/A memory (putting it back into a memory pool) when it is no
0N/A longer needed. Enabling simple debugging features like guard
0N/A bands, double free detection, etc. would be cool but certainly
0N/A not a hard requirement.
0N/A Status: Cliff started to implement this using SMS as has
0N/A been discussed at length for months, but since
0N/A SMS is not being used anywhere else in the server,
0N/A several people expressed the opinion that we should
0N/A get rid of it entirely, meaning that the buckets
459N/A need their own memory management (free list) functions.
0N/A Cliff will implement that this weekend so we at least
0N/A * Eliminate unnecessary creation of pipes in mod_cgid
0N/A * the autoconf setup should be fixed to default to using the
0N/A in a layout should be overridable on the command line. Plus,
160N/A what we do right now just doesn't seem to fully fit into how autoconf
0N/A works, eg. AC_PREFIX_DEFAULT issues.
0N/A Message-ID: <Pine.BSF.4.20.0104031557420.20876-100000@alive.znep.com>
0N/A * Document mod_file_cache.
160N/A * OS/2: Make mod_status work for spmt_os2 MPM.
160N/A * Platforms that do not support fork (primarily Win32 and AS/400)
160N/A Architect start-up code that avoids initializing all the modules
160N/A in the parent process on platforms that do not support fork.
160N/A would eliminate some code in the Win32 branch that essentially
160N/A duplicates what is in APR.
160N/A * There are still a number of places in the code where we are
0N/A losing error status (
i.e. throwing away the error returned by a
0N/A system call and replacing it with a generic error code)
0N/A * Mass vhosting version of suEXEC.
0N/A the dbmmanage employs the first-matched dbm format. This is not
160N/A necessarily the library that Apache was built with. Aught to
160N/A rewrite dbmmanage upon installation to bin/ with the proper library
0N/A Status: Mladen Turk has posted several patches and ideas.
0N/A Key question, part of htpasswd, or a seperate utility?
0N/A prefer seperate: OtherBill
0N/A * use apu_dbm in mod_auth_dbm
0N/A Status: Greg +1 (low-priority volunteer)
0N/A Justin says: "Seems like this is already there, so should we just
0N/A remove the other DBM code in that file? If you want
0N/A to use gdbm, or dbm, etc, you should tell apr-util."
0N/A Will says: "bs - I may choose the fastest - most efficient native
0N/A dbm implementation, for shared proc caches, ssl session
0N/A caching, etc, but that has nothing to do with maintaining
0N/A a userlist via dbm, which has to remain readable between
0N/A for apr-util would let us do this with just apr, though."
0N/A * Integrate mod_dav.
0N/A Some additional items remaining:
0N/A - case_preserved_filename stuff
0N/A (use the new canonical name stuff?)
0N/A - find a new home for ap_text(_header)
3686N/A - is it possible to remove the DAV: namespace stuff from util_xml?
0N/A * ap_core_translate() and its use by mod_mmap_static and mod_file_cache
0N/A are a bit wonky. The function should probably be exposed as a utility
0N/A function (such as ap_translate_url2fs() or ap_validate_fs_url() or
0N/A something). Another approach would be a new hook phase after
0N/A "translate" which would allow the module to munge what the
0N/A translation has decided to do.
0N/A Status: Greg +1 (volunteers), Ryan +1
0N/A calls ap_fixup_virutal_hosts(), ap_fini_vhost_config(), and
0N/A ap_sort_hooks() [to reduce the logic in main()]
0N/A * read the config tree just once, and process N times (as necessary)
0N/A * (possibly) use UUIDs in mod_unique_id
and/or mod_usertrack
0N/A * (possibly) port the bug fix for PR 6942 (segv when LoadModule is put
0N/A 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:
- 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)
-0: Cliff (I think the default config should be the safest possible)
