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:
. mod_lua
. documentation
. non-Unix build
. non-Unix, single-platform code

*) mod_proxy: Give ap_proxy_post_request as chance to act correctly on the status code
by setting r->status temporarily to access_status. r->status might be different than
access_status e.g. r->status could be HTTP_OK if e.g. we override the error page on
the proxy or if the error was not generated by the backend itself but by the proxy
e.g. a bad gateway.

PATCHES PROPOSED TO BACKPORT FROM TRUNK:
[ New proposals should be added at the end of the list ]
* 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
ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
Also added missing r1609688 to the patchset.
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?
* 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.

*) 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).

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.

+1: rpluem, ylavic
niq: 1. the if(worker->s->retries) {} and comment at line 2917
don't seem to make any sense.
rpluem: This is just taken over from existing code. It is just indented
differently hence part of the path I think it should be marked
as TODO section. But this should be subject to another
patch.
2. Re: error handline line 2930 - can PROXY_WORKER_IS_USABLE
not be tested BEFORE opening connection?
rpluem: We could, but we can catch more race cases with the current code
as it also catches the case where a connection establishment
took long and the worker went into error meanwhile.

Let's comment on @dev for Stefan Eissing (mod_h2) to be able to
participate.
* 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.

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...

2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff

-.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?
