79 * Review the "PatchAvailable" bugs in the bug database:
81 https://issues.apache.org/bugzilla/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&product=Apache+httpd-2&keywords=PatchAvailable
83 After testing, you can append a comment saying "Reviewed and tested".
85 * Open bugs in the bug database.
87 * See also the STATUS file in the docs/ directory, which lists documentation-specific TODO items.
90 CURRENT RELEASE NOTES:
92 * Forward binary compatibility is expected of Apache 2.4.x releases, such
93 that no MMN major number changes will occur after 2.4.1. Such changes can
94 only be made in the trunk.
96 * All commits to branches/2.4.x must be reflected in SVN trunk,
97 as well, if they apply. Logical progression is commit to trunk
98 then merge into branches/2.4.x, as applicable.
100 * Current exceptions for RTC for this branch:
104 . non-Unix, single-platform code

146 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
147 [ New proposals should be added at the end of the list ]
149 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
150 and ProxyMatch section to distinguish between normal workers and workers
151 with regex substitutions in the name. Implement handling of such workers
152 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
153 matched and used for request. PR 43513.
154 trunk patch: http://svn.apache.org/r1609680
155 http://svn.apache.org/r1609688
156 http://svn.apache.org/r1641381
157 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
158 Also added missing r1609688 to the patchset.
159 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
161 -0: covener tried to review this one in Austin with Jeff. Does the added match function
162 really cover a very narrow set of parameters with the way it skips over backreferences?
163 Also, why a new API vs. just setting the field inline?
165 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
166 backport keeps syslog logging as part of httpd core and only adds
167 API to allow other modules to be used for error logging.

181 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
182 needs 2 args which is not valid in ErrorLog manual)
183 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"

213 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_listeners_buckets-v3.patch
216 *) http: Don't remove the Content-Length of zero from a HEAD response if
217 it comes from an origin server, module or script. Allow the previous
218 behaviour (for legacy/buggy modules only, not origin) by also backporting
219 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
220 comes for free with the same commit).

222 http://svn.apache.org/r1678215
223 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
225 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
226 ints added at the end of core_server_config, the proposed merge
227 does a minor bump only.
229 *) mod_substitute: Configure patterns merge order. PR 57641

245 before the retry period is over

247 http://svn.apache.org/r1664709
248 http://svn.apache.org/r1697323
249 Backport version for 2.4.x of patch:
250 Trunk version of patch works modulo CHANGES
252 niq: 1. the if(worker->s->retries) {} and comment at line 2917
253 don't seem to make any sense.
254 rpluem: This is just taken over from existing code. It is just indented
255 differently hence part of the path I think it should be marked
256 as TODO section. But this should be subject to another
258 2. Re: error handline line 2930 - can PROXY_WORKER_IS_USABLE
259 not be tested BEFORE opening connection?
260 rpluem: We could, but we can catch more race cases with the current code
261 as it also catches the case where a connection establishment
262 took long and the worker went into error meanwhile.
264 *) util_script: Make REDIRECT_URL a complete URL (where set).
266 trunk: http://svn.apache.org/viewvc?view=revision&revision=1677702
267 2.4.x: trunk patch applies.

350 *) mod_rewrite: Fix an harmless error spotted by sparse.
351 trunk: http://svn.apache.org/r1697735
352 2.4.x: trunk patch applies.
354 ylavic: I'd prefer the unambiguous parentheses in the macros definitions,
355 as you suggested on dev@.
359 *) Allow autoindexes to work without mod_dir or mod_mime
360 trunk: http://svn.apache.org/r1701436
364 PATCHES/ISSUES THAT ARE BEING WORKED
366 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
367 fetching the request body, so to minimize the delay between it is supposed
368 to be alive and the first bytes sent: this is a best effort to prevent the
369 backend from closing because of idle or keepalive timeout in the meantime.
370 Also, handle a new "proxy-flushall" environment variable which allows to
371 flush any forwarded body data immediately. PR 56541+37920.
372 trunk patch: http://svn.apache.org/r1656259
373 http://svn.apache.org/r1656359 (CHANGES entry)
374 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
376 -0: jim: This seems to be a hit to normal performance, to handle an
377 error and/or non-normal condition. The pre-fetch is
378 expensive, and is always done, even before we know that
379 the backend is available to rec' it. I understand the
380 error described, but is the fix actually worth it (plus
381 it seems to allow for a DDoS vector).
382 ylavic: It seems to me that the problem is real since we reuse the
383 connection before prefetching 16K (either controlled by the
384 client, or by an input filter), we currently always prefetch
385 these bytes already. Regarding performance I don't see any
386 difference (more cycles) compared with the current code.
387 However I think I failed to rebuild the header_brigade when
388 the proxy loop is retried (ping), so I need to rework this.
389 Do you think we'd better remove the prefetch, or maybe just
390 make it nonblocking (by default)?
391 jim: Non-blocking seems the best way to handle...

426 compiled by the build compiler instead of the host compiler.
427 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

432 fuankg: on hold until we agree for a better and more simple solution ...
434 * Makefile.win: Added copying of .vbs / .wsf CGIs to Windows install target.
435 Moved fixing of shebang to separate target so that it is
436 no longer executed by default and all CGIs remain inactive.

440 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
443 This commit is essentially deciding that an httpd install on
444 Windows now has printenv/testcgi written in 2 more languages.
445 To the extent that the usefulness is that it shows how to make scripts
446 of these types executable by httpd, I believe that the documentation
447 is the proper place to solve that. To the extent that the usefullness
448 is to show how to implement a CGI in these particular languages, I believe
449 that the httpd distribution and documentation in general is not the
450 place for that. Historically these types of scripts have caused problems
451 for downstream vendorsas well as newbies (and sometimes the intersection
452 of those two groups) who don't understand that these are information leaks
453 once they are enabled, and the subtlety of the way they are disabled ("Apache
454 messed up the first line; let me fix that") contributes to that.
455 fuankg notes: I've just added a big warning to all CGI scripts which should now
456 make absolutely clear that these CGIs are for testing purpose only - so those
457 who enable those scripts with inserting the right shebang should be 100% aware
458 of any risks (this should cover your last point).
459 jim: trawick, does the above address your concerns?
460 trawick: to some extent (somebody reading the script gets an idea)
461 Why isn't the configuration requirement documented instead
462 of described indirectly in a sample?
463 Why are these new samples added to the install without three
464 votes? (I didn't veto it; put your name next to the two
465 existing ones and I'll be satisified that enough people
466 considered this addition as an appropriate solution for a
467 real httpd usability problem.)
468 wrowe: I'd agree with trawick, and suggest that these scripts can begin
469 their life somewhere in the manual/ tree. This really seems like
470 the place where /usr/share/httpd/examples/ would be useful, but
471 there isn't an ordinary directory for that. Since we want none
472 of the scripts to function 'out of the box', what about a new
473 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
