Contributors looking for a mission:
* Just do an egrep on "TODO" or "XXX" in the source.
* Review the bug database at: http://issues.apache.org/bugzilla/
* Review the "PatchAvailable" bugs in the bug database:
https://issues.apache.org/bugzilla/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&product=Apache+httpd-2&keywords=PatchAvailable
After testing, you can append a comment saying "Reviewed and tested".
* Open bugs in the bug database.
* See also the STATUS file in the docs/ directory, which lists documentation-specific TODO items.
CURRENT RELEASE NOTES:
* Forward binary compatibility is expected of Apache 2.4.x releases, such
that no MMN major number changes will occur after 2.4.1. Such changes can
only be made in the trunk.
* All commits to branches/2.4.x must be reflected in SVN trunk,
as well, if they apply. Logical progression is commit to trunk
then merge into branches/2.4.x, as applicable.
* Current exceptions for RTC for this branch:
. http/2 - mod_http2
. mod_lua
. documentation
. non-Unix build
. non-Unix, single-platform code
RELEASE SHOWSTOPPERS:
PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
[ start all new proposals below, under PATCHES PROPOSED. ]
*) mod_ssl: Fix "warning: variable 'hssc' set but not used".
2.4.x only, r1715255 merged in 2.4.18 missed this (trunk) hunk.
2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ssl_hssc_warning.patch
+1: ylavic, rpluem, covener
PATCHES PROPOSED TO BACKPORT FROM TRUNK:
[ New proposals should be added at the end of the list ]
*) mod_alias: Introduce expression parser support for Alias, ScriptAlias
and Redirect. Limit Redirect expressions to directory (Location) context
and redirect statuses (implicit or explicit).

+1: minfrin
* core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
its parameter when starting httpd as single process (httpd -X).
trunk patch: http://svn.apache.org/r1711479
2.4.x patch: trunk works
+1: jkaluza, jim
minfrin: Needs extra parens to suppress a warning:
prefork.c:1319:16: note: place parentheses around the assignment
to silence this warning
jailletc36: This has been done in r1711919
ylavic: Also, I don't think the changes on worker/event are needed,
prefork only requires the accept mutex in ONE_PROCESS mode.
*) mod_ssl: Fix missing TLS Upgrade/Connection headers on OPTIONS * requests
(Note that this is simply a necessary band-aid, and still won't allow h2c
to peacefully coexist with tls/n.n upgrades, because Upgrade phase needs
to come earlier, not as a handler, and the bogus connection-close behavior
must be removed before the Protocol API can handle TLS upgrade.)
PR58688
trunk patch: http://svn.apache.org/r1717816
+1: wrowe, icing
ylavic: how about adding !ap_request_has_body(r) to the test then?
wrowe responds: nonstarter, as discussed on list.
*) mod_ssl: Free dhparams when getting DH params. This fixes issue when
SSLCryptoDevice does not get unregistered because of non-zero refcount
during the mod_ssl unload happening on httpd startup.

is received from an origin server in multiple batches and forwarded by
mod_proxy.

2.4.x patch: trunk works
+1 covener
PATCHES/ISSUES THAT ARE BEING WORKED
*) http: Don't remove the Content-Length of zero from a HEAD response if
it comes from an origin server, module or script. Allow the previous
behaviour (for legacy/buggy modules only, not origin) by also backporting
the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
comes for free with the same commit).
trunk patch: http://svn.apache.org/r1554303
http://svn.apache.org/r1678215
2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
+1: ylavic, jim
ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
ints added at the end of core_server_config, the proposed merge
does a minor bump only.
minfrin: Two new directives need to be documented.
* mod_proxy_http: Don't establish or reuse a backend connection before pre-
fetching the request body, so to minimize the delay between it is supposed
to be alive and the first bytes sent: this is a best effort to prevent the
backend from closing because of idle or keepalive timeout in the meantime.
Also, handle a new "proxy-flushall" environment variable which allows to
flush any forwarded body data immediately. PR 56541+37920.
trunk patch: http://svn.apache.org/r1656259
http://svn.apache.org/r1656359 (CHANGES entry)
2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
+1: ylavic
-0: jim: This seems to be a hit to normal performance, to handle an
error and/or non-normal condition. The pre-fetch is
expensive, and is always done, even before we know that
the backend is available to rec' it. I understand the
error described, but is the fix actually worth it (plus
it seems to allow for a DDoS vector).
ylavic: It seems to me that the problem is real since we reuse the
connection before prefetching 16K (either controlled by the
client, or by an input filter), we currently always prefetch
these bytes already. Regarding performance I don't see any
difference (more cycles) compared with the current code.
However I think I failed to rebuild the header_brigade when
the proxy loop is retried (ping), so I need to rework this.
Do you think we'd better remove the prefetch, or maybe just
make it nonblocking (by default)?
jim: Non-blocking seems the best way to handle...
PATCHES/ISSUES THAT ARE STALLED
* core: Add ap_errorlog_provider to make ErrorLog logging modular. This
backport keeps syslog logging as part of httpd core and only adds
API to allow other modules to be used for error logging.

2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
+1: jkaluza
+1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
needs 2 args which is not valid in ErrorLog manual)
trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
(sorry, haven't finished reviewing completely)
jim: What is the status of this??
* mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
and ProxyMatch section to distinguish between normal workers and workers
with regex substitutions in the name. Implement handling of such workers
in ap_proxy_get_worker(). Fixes the bug when regex workers were not
matched and used for request. PR 43513.
trunk patch: http://svn.apache.org/r1609680
http://svn.apache.org/r1609688
http://svn.apache.org/r1641381

2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
+1: ylavic
-0: covener tried to review this one in Austin with Jeff. Does the added match function
really cover a very narrow set of parameters with the way it skips over backreferences?
Also, why a new API vs. just setting the field inline?

2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
+1 fuankg, gsmith
-.8: trawick
This commit is essentially deciding that an httpd install on
Windows now has printenv/testcgi written in 2 more languages.
To the extent that the usefulness is that it shows how to make scripts
of these types executable by httpd, I believe that the documentation
is the proper place to solve that. To the extent that the usefullness
is to show how to implement a CGI in these particular languages, I believe
that the httpd distribution and documentation in general is not the
place for that. Historically these types of scripts have caused problems
for downstream vendorsas well as newbies (and sometimes the intersection
of those two groups) who don't understand that these are information leaks
once they are enabled, and the subtlety of the way they are disabled ("Apache
messed up the first line; let me fix that") contributes to that.
fuankg notes: I've just added a big warning to all CGI scripts which should now
make absolutely clear that these CGIs are for testing purpose only - so those
who enable those scripts with inserting the right shebang should be 100% aware
of any risks (this should cover your last point).
jim: trawick, does the above address your concerns?
trawick: to some extent (somebody reading the script gets an idea)
Why isn't the configuration requirement documented instead
of described indirectly in a sample?
Why are these new samples added to the install without three
votes? (I didn't veto it; put your name next to the two
existing ones and I'll be satisified that enough people
considered this addition as an appropriate solution for a
real httpd usability problem.)
wrowe: I'd agree with trawick, and suggest that these scripts can begin
their life somewhere in the manual/ tree. This really seems like
the place where /usr/share/httpd/examples/ would be useful, but
there isn't an ordinary directory for that. Since we want none
of the scripts to function 'out of the box', what about a new
cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
might work?
