cf6ce969525bc8478dee20737ef3b884dc46c43afuankg Status:

* Use APR to get rid of more platform dependancies.

Status: Ryan Bloom <rbb@covalenet.net> is working on this.

* The connection status table is not very efficient. Also, very few stats

are exported to the connection status table (easy to fix), and mod_status

is ugly.

* Mass vhosting version of suEXEC.

* Replace tables with a proper opaque ADT that has pluggable

implementations (including something like the existing data type,

plus hash tables for speed, with options for more later).

Status: fanf is working on this.

* configuration option to use *DBM

Status: Greg +1 (volunteers)

* add SDBM into src/lib/sdbm/ as a default/fallback DBM implementation.

SDBM is used by Perl, mod_dav, mod_sssl, others for basic DBM support.

Status: Greg +1 (volunteers)

* Integrate mod_dav.

Message-id: <20000625173247.M29590@lyra.org>

Status: in process.

- APR does not provide a couple needed things: chmod()

and ap_finfo_t.st_dev.

- expat-lite needs to be brought up to parity with the 1.3

vsn and inserted into the config/build process

- SDBM needs to go into the config/build process

- fix up include dirs to pick up expat-lite, sdbm, dav/main

- APR-ization to the dav/fs/ stuff

- case_preserved_filename stuff

* ap_core_translate() and its use by mod_mmap_static 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 mod_mmap_static to munge what the translation has

decided to do.

Status: Greg +1 (volunteers), Ryan +1

* Go through ap_config.h and namespace-protect the symbols (e.g. USE_*).

Some symbols can/should move to mpm_common.h where possible.

* 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)

* add a version number to ap_initialize() as an extra failsafe against

(APR) library version skew.

Status: Greg +1, Ryan -1

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

completely.

* 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.

* The mod_cgid daemon process isn't always cleaned up when httpd

gets SIGTERM. Jeff thinks it may be as simple as registering

the daemon process for cleanup with the proper pool, but he hasn't

looked at it in enough detail.

* The MM library is built as static and shared library. This should

be set up to build only the required version.

Other features that need writing:

* Finish infrastructure in core for async MPMs

Status: post 2.0

* TODO in source -- just do an egrep on "TODO" and see what's there

Documentation that needs writing:

* Mod_status docs are needed.

* The concept of MPMs, especially if we ship more than one MPM for a

given platform

* New directives in the various MPMs and appropriate links from

obsolete directives in core.html to the MPM documentation.

* Revise manual/stopping.html and the last part of

manual/misc/perf-tuning.html to take account of the MPMs.

* API documentation

Status: Ben Laurie has written some hooks documentation

(apache-2.0/htdocs/hooks.html)

* Changes since 1.3.9 can be more easily seen in the commitlog file

dev.apache.org:/home/cvs/CVSROOT/commitlogs/apache-2.0

which includes some of Roy's comments when the changes were

committed in rough change-sets by purpose. Note that the commitlog

does not show the contents of new files until later.

* mod_dav documentation (once integrated)

Available Patches:

* Mike Abbott's <mja@trudge.engr.sgi.com> patches to improve

performance

Status: These were written for 1.3, and are awaiting a port to

2.0

* Jim Winstead's <jimw@trainedmonkey.com> patch to add CookieDomain and

other small mod_usertrack features

Open issues:

* What do we do about mod_proxy?

* Which MPMs will be included with Apache 2.0?

* Is conf/highperformance.conf-dist obsolete? It looks obsolete.
