Contributors looking for a mission:
* Just do an egrep on "TODO" or "XXX" in the source.
* Review the bug database at:
* Review the "PatchAvailable" bugs in the bug database:
After testing, you can append a comment saying "Reviewed and tested".
* Open bugs in the bug database.
* Forward binary compatibility is expected of Apache 2.2.x releases, such
that no MMN major number changes will occur. Such changes can only be
made in the trunk. Note 2.2.18 contained an incompatible ABI change,
subsequently corrected, and should not be referenced.
* All commits to branches/2.2.x must be reflected in SVN trunk,
as well, if they apply. Logical progression is commit to trunk,
get feedback and votes on list or in STATUS, then merge into
branches/2.2.x, as applicable.
[ start all new proposals below, under PATCHES PROPOSED. ]
[ New proposals should be added at the end of the list ]
* mod_cache: Realign the cache_quick_handler() to behave identically
to the default_handler() when reacting to errors when writing to the
filter stack. Stops APR errors appearing in access_log as result codes.
Trunk patches:
2.2.x patch:
+1: minfrin
trawick: any reason it shouldn't be completely aligned with default_handler's
choice to return OK vs. 500?
* core: Support wildcards in both the directory and file components of
the path specified by the Include directive.
Trunk patch:
2.2.x patch:
Submitted by: minfrin, poirier
+1: minfrin, jim, poirier
-1: wrowe [This introduces new invalid paths which do not resolve to any
configuration file paths, increasing the probability of unreported
syntax errors to further confuse the administrator.]
* srclib/pcre and vendor/pcre
update to pcre-7.8
outcome: remove from trunk, leave alone in branches/2.2.x and branches/2.0.x
* core, authn/z: Avoid calling access control hooks for internal requests
with configurations which match those of initial request. Revert to
original behaviour (call access control hooks for internal requests
with URIs different from initial request) if any access control hooks or
providers are not registered as permitting this optimization.
Introduce wrappers for access control hook and provider registration
which can accept additional mode and flag data. Convert common
provider version strings to macros.
The core purpose of this pile of patches is to avoid unnecessary
authn/z hooks when a single request spawns large numbers of internal
requests to which an identical set of httpd configurations apply.
This permits modules such as mod_authn_dbd and mod_dav to work together
Because certain external modules such as mod_authz_svn rely on the old
behaviour, this optimization can be made only when all authn/z hooks and
providers are registered with the appropriate flag.
It would be excellent if Windows and NetWare people could ensure this
builds correctly.
In particular, mod_auth.h must be included into request.c and I've left
mod_auth.h under modules/aaa rather than try to replicate wrowe's work
in trunk moving all the include files around.
I'm open to suggestions that this remain in trunk only, but in that case,
it would be very helpful to know whether most people expect a 2.4 branch
or just a 3.0 branch to be next. If 3.0, some of the backwards
compatibility work could potentially be ditched.
Trunk version of patches: (trunk MMN bump) (reverted by r659160)
Backport version for 2.2.x of patch:
+1: chrisd
-0: jim (would prefer to see in 2.4, and to push 2.4 out)
* beos MPM: Create pmain pool and run modules' child_init hooks when
entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
Otherwise modules' child_init hooks appear to never be executed.
Also, destroying pmain ensures that cleanups registered in modules'
child_init hooks are performed (e.g., mod_log_config and mod_dbd).
Trunk version of patch:
2.2.x version of patch:
+0: chrisd (abstaining; unable to test)
* PKCS#7: backport PCKS#7 patches from trunk.
+1 ben
jerenkrantz: What's the revision number to backport?
wrowe asks: ditto jerenkrantz
sctemme: svn blame suggests r424707
rpluem: Digging through the history suggests that
need to be added to this. See also
and follow ups for more details.
needs r930063 to avoid a memory leak, +1 with r930063.
* prefork MPM: simple patch to enable mod_privileges.
trunk: N/A (this patch substitutes for the availability of
drop_privileges hook).
2.2.x patch:
+1: niq, igalic
* unixd: set suexec_enabled correctly when httpd is run by non-root
PR 42175
Trunk Patch:
2.2.x Patch:
+1: niq
-0: wrowe; Please refer to man 'access' BUGS section about linux 2.4
vs 2.6 kernels, potentially a suspect test for root.
sf: Couldn't the linux 2.4 bug be worked around by calling access
twice? Once with R_OK and once with X_OK.
wrowe: It would seem we only need to test for X_OK?
* mod_disk_cache: Decline the opportunity to cache if the response is
a 206 Partial Content. This stops a reverse proxied partial response
from becoming cached, and then being served in subsequent responses.
Trunk patch:
2.2.x patch:
+1: minfrin
niq asks: I can see the logic of not cacheing partial responses,
but why should mod_disk_cache worry about them if mod_cache allows
them, as in the following proposal?
rpluem says: As poirier correctly mentions, the same must be done for mod_mem_cache
as well.
*) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
Response if they so choose to do so. Previously an attempt to cache a 206
was arbitrarily allowed if the response contained an Expires or
Cache-Control header, and arbitrarily denied if both headers were missing.
Trunk patch:
2.2.x Patch:
+1: minfrin
-1: rpluem: Until the patch proposal above for mod_disk_cache is backported
and a similar patch for mod_mem_cache is proposed (no backport
possible since mod_mem_cache is no longer in trunk) and
* config: fix/optimize SSL connections for IE6 browsers
PR 49484
Trunk patch:
2.2 patch: should apply cleanly
+1: gstein
-0: sf: If we change it, then change it to something that will be OK for
MSIE 10, too. Also, some people recommend keeping ssl-unclean-shutdown
for newer versions of MSIE.
See and
the links therein.
* mod_proxy: Release the backend connection as soon as EOS is detected,
so the backend isn't forced to wait for the client to eventually
acknowledge the data.
Trunk patch:
2.2.x patch:
+1: minfrin
+1: jim (requires mmn bump due to proxy_conn_rec)
rpluem says: r1052224 r1052314 need to be added as well as the patch above
has a thread safety issue.
minfrin: r1055246 needs to be added to r1052314 to ensure the cleanup
isn't attempted twice.
rpluem says: Mind to update the 2.2.x version of the patch with r1052224,
r1052314, r1055246 and r1055570 (Comment fix by Jim)?
