- for beta
- +1 : Aaron
- +0 : Lars, Justin, trawick
- -0 : OtherBill
- -1 : BillS, Ian, gregames, BrianP, Jim
- bumps since original tag:
- * mod-dir patch
- * scoreboard x2 : 1 to fix gracefull restarts
- 1 to fix netware
- * win32/locks.c : to fix mod_rewrite on win32
-
- problems with v31:
- * libtool/binbuild on AIX -- possible addition of patched
- binbuild.sh to 31-beta roll
- +1: Ian, Justin
- +0:
- -1:
- Jeff says: We can't do anything about libtool since AIX
- needs a version that won't work on some
- platforms. Handle this in the README.
- The binbuild issue isn't AIX. It is
- something that could happen anywhere that
- the binbuild-er has their own expat.
- Handle this by patching binbuild.sh for a
- beta roll or putting a patch in the README for
- use by people who want to do binbuild but
- have expat installed locally.
- gregames: why can't we roll a second tarball with the
- appropriate libtool version? doesn't
- Darwin need it as well as AIX?
-
- * erroneous check in an AP_DEBUG_ASSERT() call. Only happens
- in maintainer mode. Fixed in modules/http/http_protocol.c
- revision 1.391
-
- * seg faults in core_input_filter when the client goes away
- before any POST body bytes are received.
- Jeff committed a fix with server/core.c revision 1.144.
- Justin committed a fix with server/protocol.c revision 1.78
- (server/protocol.c revision 1.81 demotes a potentially
- annoying error message)
-
- * FirstBill reports problem [re]starting as-a-service, shared
- score is suspect. OtherBill is investigating... has found
- . created restart and shutdown events, only restart
- survived initialization on XP, although breaking into
- the debugger interferes with reproducing the bug.
- Perhaps in FirstBill's example _restart didn't survive.
- . Scoreboard appears irrelevant to the problem.
- . This looks like handle corruption in NT/XP
- . Args are not initialized correctly when the -k install
- is given.
- OtherBill will not create Win32 binaries due to this bug.
-
- * mod_auth_dbm can't open a Berkeley DB password file on Unix
- Justin postulates that this might be related to the fact
- that mod_auth_dbm wasn't using apr-util. See
- modules/aaa/mod_auth_dbm.c revision 1.42 and
- module/aaa/config.m4 revision 1.54. Also, FreeBSD's DB
- variant was not properly detected. See
- apr-util/build/apu-conf.m4 revision 1.31 and
- apr-util/dbm/apr_dbm_berkeleydb.c revision 1.17.
-
- * Madhu reports that the worker MPM doesn't shutdown nicely
- after a stress test.
-
- * mod_autoindex displays the wrong icon for subdirectories
- on Unix
- possible fix in modules/generators/mod_autoindex.c r1.93.
-
- * anon shared memory not allocating enough
- (fix is apr/shm/unix/shm.c 1.14)
+ * 34 status: Let's get all API changes and showstoppers in this one.
+ Please.
FINAL RELEASE SHOWSTOPPERS:
- * ap_directory_walk skips some per-dir config merge functions
- if there is no "<Directory />" block in the configuration
- Message-ID: <m3itbdiijq.fsf@rdu163-40-092.nc.rr.com>
- * That is very unlikely, merges are additive. Much more likely,
- the default SetOutputFilter default or merge is borked.
- Unless it's the code that permits 'null' merges, per module.
- Still, it's probably in SetOutputFilter's behavior.
- * BrianP notes: directory_walk's handling of trailing slashes
- appears to be the cause: <3C1CF721.1090300@pacbell.net>
-
- * If any request gets to the core handler, without a flag that this
- r->filename was tested by dir/file_walk, we need to 500 at the very
- end of the ap_process_request_internal() processing. This provides
- authors of older modules better compatibility, while still improving
- the security and robustness of 2.0.
- Status: still need to decide where this goes, OtherBill comments...
- Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
- we need to look at halting this in the 'default handler' case,
- and that implies pushing the 'handler election' into the request
- internal processing phase from the run request phase.
-
- * Convert all instances of the old apr_lock_t type to the new
- types (once they are fully supported in APR).
- Status: Aaron is working on converting INTRAPROCESS
- to apr_thread_mutex_t types. Full replacements for
- LOCKALL and CROSS_PROCESS are not yet complete on all
- platforms, and should only be used in MPMs like worker
- with limited OS exposure.
- BrianP asks: "Is this really a showstopper?"
- IanH says: "If we don't do it before we go live we will have 2
- different API's to support in APR"
-
- * [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.
- If you can provide evidence that it can be reproduced
- outside of httpd-test, then it's a showstopper. I
- think it's a perl or a httpd-test problem."
- Not a showstopper: Justin
+ * API changes planned for 2.0 that should happen before the
+ GA release:
+ * Free lists for bucket allocation
- * [Ken] A binbuild installation picks up the right libraries when
- running apachectl because we set the appropriate environment
- variable, but ab, htpasswd, etc. don't know how to pick up apr,
- apr-util, etc.
- Message-ID: <20020116000226.GA15991@ebuilt.com>
- Justin says: "You could always build all of the binaries
- statically if you don't want to let libtool
- handle it. At most, I don't consider this a
- a release showstopper as it is a packaging issue."
- Ken sez: "Showstopper because, until it's the default, it
- violates the P of LA. Binaries will give strange
- errors and not run if moved."
- Status: Aaron volunteers: I'll commit a patch to allow all
- the support binaries to be built statically against
- libapr/libaprutil/etc and then enable it in binbuild.
- gregames says: what about httpd? yeah, it works at the moment
- if you use apachectl. But I've already heard
- complaints about not being able to execute
- httpd directly.
+ * We do not properly substitute the prefix-variables in the configuration
+ scripts or generated-configs. (i.e. if sysconfdir is etc,
+ httpd-std.conf points to conf.)
+ Aaron says: This is not a showstopper, these problems have existed
+ for as long as I can remember. It would be nice to fix
+ them but they are not new.
+ Not a showstopper: Jeff, Aaron, BillS, gregames
CURRENT VOTES:
- * Should we always build binaries statically unless otherwise
+ * Should we always build [support*] binaries statically unless otherwise
indicated?

RELEASE NON-SHOWSTOPPERS BUT WOULD BE REAL NICE TO WRAP THESE UP:
+ * If any request gets through ap_process_request_internal() and is
+ scheduled to be served by the core handler, without a flag that this
+ r->filename was tested by dir/file_walk, we need to 500 at the very
+ end of the ap_process_request_internal() processing so sub_req-esters
+ know this request cannot be run. This provides authors of older
+ modules better compatibility, while still improving the security and
+ robustness of 2.0.
+
+ Status: still need to decide where this goes, OtherBill comments...
+ Message-ID: <065701c14526$495203b0$96c0b0d0@roweclan.net>
+ [Deleted comments regarding the ap_run_handler phase, as irrelevant
+ as BillS points out that "common case will be caught in
+ default_handler already (with the r->finfo.filetype == 0 check)"
+ and the issue is detecting this -before- we try to run the req.]
+
+ gregames says: can this happen somehow without a broken module
+ being involved? If not, why waste cycles trying to defend against
+ potential broken modules? It seems futile.
+ wrowe counters: no, it shouldn't happen unless the module is broken.
+ 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
+ or we break modules that are unwilling to hook map_to_storage.
+
+ * Rewrite core_output_filter. It is nearly impossible to support
+ it with predictable results as it is implemented now.
+
+ * Convert all instances of the old apr_lock_t type to the new
+ types.
+ Status: Aaron has converted all but the perchild MPM to
+ use the new lock API. Since perchild has been put
+ on the back burner, this is no longer a showstopper.
+ Aaron will patch perchild as soon as it becomes
+ buildable again.
+
+ * 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.
+
+ * htpasswd blindly processes the file you give it, and does no
+ sanity checking before totally corrupting whatever file it was
+ you thought you had. It should check the input file and bail
+ if it finds non-comment lines that do not contain exactly 1
+ ':' character.
+ Message-ID: <20020217150457.A31632@clove.org>
+
+ * 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.
+ If you can provide evidence that it can be reproduced
+ outside of httpd-test, then it's a showstopper. I
+ think it's a perl or a httpd-test problem."
+ Not a showstopper: Justin
+
* Usage of APR_BRIGADE_NORMALIZE in core_input_filter should be
removed if possible.

Not a showstopper: justin, wrowe, trawick, stoddard, Jim, Ian, Aaron,
gregames
- * Make some modifications to the scoreboard creation routines,
- prefer anonymous shared memory, and allow a configuration
- directive to override the defaults.
- Message-ID: <20020130080804.C16977@clove.org>
- Status: Aaron volunteers
-
* 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>
- * Recent changes to ap_rgetline may have broken EBCDIC boxes.
- Message-ID: <20020122072605.GF28051@ebuilt.com>
- Justin says: "I don't have an EBCDIC box to test on. A potential
- solution is to split out ap_rgetline into two
- functions as described in this message."
- gregames says: I see the breakage now, and volunteer to fix it
- when things calm down a little. It looks OK when
- there are complete lines and no mime continuations.
-
- * Modify the worker MPM so that it doesn't need to create and
- destroy a pool for each request--possibly by adopting a
- leader/follower model in which each worker owns a persistent
- ptrans pool (like the prefork MPM) and the workers take
- turns acting as listeners...this approach might also help
- reduce context-switching
-
* CGI single-byte reads
BrianP suggests that this is caused by the ap_scan_script_header_err()
routine, which will do single-byte reads until it finds the end
to read from.
Proposed solution in:
Message-ID: <3C36ADAF.60601@cnet.com>
+ Update 3/23/2002: solution implemented for mod_cgi, mod_cgid remains
+ to be fixed
* Try to get libtool inter-library dependency code working on AIX.
Message-ID: <cm3n10lx555.fsf@rdu163-40-092.nc.rr.com>
to both parent and child for writing. Then we just need to
figure out how to do graceless on non-threaded MPMs.
- * revamp the input filter behavior, per discussions since
- February (and especially at the hackathon last
- April). Specifically, ap_get_brigade will return a brigade with
- *up to* a specific number of bytes, or a "line" of data. The
- read may be blocking or nonblocking. ap_getline() will be
- refactored into apr_brigade_getline(), and then DECHUNK can use
- f->next (ap_getline will always read "top of input stack"). Also
- fix the bug where request body content will end up closing the
- connection (buggering up persistent conns).
- Status: Justin is working on this as fast as he can.
- The core input filters, HTTP-related filters, mod_ssl,
- mod_proxy, and ap_[r]getline are switched to the new logic.
-
- - socket bucket and core input filter changes. see end of
- message ID (Feb 27): <20010227075326.S2297@lyra.org>

* 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
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
The current porting state is summarized in modules/ssl/README. The
remaining work includes:
(1) stablizing/optimizing the SSL filter logic
- (2) Enabling the various SSL caching mechanisms (shmcb, shmht)
- (3) Enabling SSL extentions
- (4) Trying to seperate the https filter logic from mod_ssl -
+ (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.
- Justin: mod_ssl filter logic is redone, so that should be fine.
- Madhu has submitted a patch for SSL caching - however, I
- am -0 on that patch as I *think* we could implement the
- shared memory another way that is much cleaner (i.e.
- treat shmem directly as a dbm via APR routines). Justin
- also thinks that the https filter logic may be sufficiently
- decoupled now, but isn't really sure.
* Performance & Debug: Eliminate most (and perhaps all) of the
malloc/free calls in the bucket brigade code. Need some
have something to look at/compare with.
* Eliminate unnecessary creation of pipes in mod_cgid
- Status: Ken asks, didn't Jeff fix this when he fixed the queue
- overrun?
-
- * the autoconf setup should be fixed to default to using the
- "Apache" layout from config.layout, and each variable settable
- in a layout should be overridable on the command line. Plus,
- what we do right now just doesn't seem to fully fit into how autoconf
- works, eg. AC_PREFIX_DEFAULT issues.
- Message-ID: <Pine.BSF.4.20.0104031557420.20876-100000@alive.znep.com>
* Combine log_child and piped_log_spawn. Clean up http_log.c.
Common logging API.
useful as a perl dbm management example? If we keep it,
do we address the issue above?
- * use apu_dbm in mod_auth_dbm
- Status: Greg +1 (low-priority volunteer)
- Justin says: "Seems like this is already there, so should we just
- remove the other DBM code in that file? If you want
- to use gdbm, or dbm, etc, you should tell apr-util."
- Will says: "bs - I may choose the fastest - most efficient native
- dbm implementation, for shared proc caches, ssl session
- caching, etc, but that has nothing to do with maintaining
- a userlist via dbm, which has to remain readable between
- builds/machines, etc. The use-multiple database schema
- for apr-util would let us do this with just apr, though."
- Ian says: "multi-dbm is in, but it still has ndbm support hardcoded
- is this still required? isn't ndbm supported via gdbm?"
-
-
* Integrate mod_dav.
Some additional items remaining:
- case_preserved_filename stuff
* 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.
* 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:
+ Message-ID: <Pine.LNX.4.44.0203011354090.16457-200000@deepthought
