* 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".

* 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

+1: jkaluza, jim
jchampion: Looks like the headers require GCC extensions to compile, so
mod_journald can't be configured in maintainer mode (-std=c89).
Can anyone else reproduce, or is it just my distro?

2.4.x: trunk patches work, final view:
http://home.apache.org/~elukey/httpd-2.4.x-core-last_modified_tz_logging.patch
The problem has been discussed in dev@ extensively but we did not reach a common
agreement about how to proceed in the long term. While we wait, I would really like
to introduce useful logs for the users (the starting point of this change was a users@
email thread). If this is not the right way to go I will move the patch to other
sections of STATUS (stalled or being worked).
The code has been tested with a simple PHP script returning different Last-Modified
headers (GMT now, GMT now Europe/Paris, GMT tomorrow, GMT yesterday, PST now).
+1: elukey
*) 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...
* mod_dav: Allow other modules to become providers and add ACLs
to the DAV response. Requires a release of apr-util v1.6.
trunk patch: http://svn.apache.org/r1748322
2.4.x: trunk works modulo CHANGES/MMN
+1: minfrin
rpluem asks: Will this compile with apr-util < v1.6 and keep
mod_dav working (without the new features of the patch of course)?
I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
(see the discussion around ap_cstr_casecmp[n] an apr 1.6)
minfrin: Yes, as you can see in the patch everything applies only
if APR_XML_X2T_PARSED is defined, and the patch was tested with
both apr-util v1.6 and apr-util v1.5.
-1: jorton, breaks binary backwards compat per dev@ discuss
msgid <20160902120654.GA12674@redhat.com>
(& also, making the structure change with apr-util version
means it breaks binary compat across an apr-util upgrade?)
* Support PCRE2 (10.x) in place of PCRE (8.x).
Submitted by: wrowe, Petr Pisar [ppisar redhat.com]
trunk patches:
http://svn.apache.org/r1773454
http://svn.apache.org/r1773741
http://svn.apache.org/r1773742
http://svn.apache.org/r1773839
http://svn.apache.org/r1773870
http://svn.apache.org/r1773882
wrowe notes that the current code is too inefficient, owing to the fact
that the ovector is a required allocation and is no longer allocated on
the stack, by design. The correct fix is an apr userdata allocation on
the appropriate pool, which would be thread-safe, but the actual API of
ap_regexec[_len]() offers us no pool. We cannot associate that pool with
the ap_regex_t, because a single regex may be used by many threads in
parallel and is not thread-safe beyond initialization.
So the only fix allowing us to use PCRE 10 in httpd 2.4 would be to write
this as a thread safe storage buffer for the majority of cases (<10 $args)
and we don't have a portable tls mechanism to do so.
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/~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 satisfied 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?
* core: block Define and Undefine in vhost and directory context. Because
it is EXEC_ON_READ, it "breaks out" of these contexts anyway.
