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
106 RELEASE SHOWSTOPPERS:
109 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
110 [ start all new proposals below, under PATCHES PROPOSED. ]
114 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
115 [ New proposals should be added at the end of the list ]
117 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
118 backport keeps syslog logging as part of httpd core and only adds
119 API to allow other modules to be used for error logging.

150 *) http: Don't remove the Content-Length of zero from a HEAD response if
151 it comes from an origin server, module or script. Allow the previous
152 behaviour (for legacy/buggy modules only, not origin) by also backporting
153 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which

157 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
159 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
160 ints added at the end of core_server_config, the proposed merge
161 does a minor bump only.

221 2.4.x patch: trunk works (module CHANGES)
223 ylavic: while at it, I also included r1678763 which is only an
224 optimization, but allows to keep code in sync with trunk.
226 *) mod_proxy: Fix ProxySourceAddress binding failure with AH00938. PR 56687.
227 trunk patch: http://svn.apache.org/r1703902
228 2.4.x patch: trunk works (module CHANGES)

282 2.4.x patch: https://people.apache.org/~kbrand/mod_ssl-2.4.x-disable-sslv3.diff
284 ylavic: Should we really change the (implicit) default in 2.4.x at
285 this stage (and potentially break existing configuratios w/o
286 SSLProtocol which used to work with SSLv3 only capable clients)?
288 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
289 and Redirect. Limit Redirect expressions to directory (Location) context

296 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
299 * MPMs: Follow up to r1705492 (SO_REUSEPORT). Add missing (and harmless)
300 backport hunk (for consistency with trunk and 2.4.x's worker/event).
301 trunk patch: http://svn.apache.org/r1629916
302 2.4.x patch: trunk works
306 PATCHES/ISSUES THAT ARE BEING WORKED
308 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
309 fetching the request body, so to minimize the delay between it is supposed
310 to be alive and the first bytes sent: this is a best effort to prevent the
311 backend from closing because of idle or keepalive timeout in the meantime.
312 Also, handle a new "proxy-flushall" environment variable which allows to
313 flush any forwarded body data immediately. PR 56541+37920.
314 trunk patch: http://svn.apache.org/r1656259
315 http://svn.apache.org/r1656359 (CHANGES entry)
316 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
318 -0: jim: This seems to be a hit to normal performance, to handle an
319 error and/or non-normal condition. The pre-fetch is
320 expensive, and is always done, even before we know that
321 the backend is available to rec' it. I understand the
322 error described, but is the fix actually worth it (plus
323 it seems to allow for a DDoS vector).
324 ylavic: It seems to me that the problem is real since we reuse the
325 connection before prefetching 16K (either controlled by the
326 client, or by an input filter), we currently always prefetch
327 these bytes already. Regarding performance I don't see any
328 difference (more cycles) compared with the current code.
329 However I think I failed to rebuild the header_brigade when
330 the proxy loop is retried (ping), so I need to rework this.
331 Do you think we'd better remove the prefetch, or maybe just
332 make it nonblocking (by default)?
333 jim: Non-blocking seems the best way to handle...
335 PATCHES/ISSUES THAT ARE STALLED
337 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
338 and ProxyMatch section to distinguish between normal workers and workers
339 with regex substitutions in the name. Implement handling of such workers
340 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
341 matched and used for request. PR 43513.
342 trunk patch: http://svn.apache.org/r1609680
343 http://svn.apache.org/r1609688
344 http://svn.apache.org/r1641381
345 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
346 Also added missing r1609688 to the patchset.
347 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
349 -0: covener tried to review this one in Austin with Jeff. Does the added match function
350 really cover a very narrow set of parameters with the way it skips over backreferences?
351 Also, why a new API vs. just setting the field inline?
353 * mod_systemd: New module, for integration with systemd on Linux.

376 504 Gateway Timout as opposed to 502 Bad Gateway
377 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
378 2.4.x patch: trunk patch works modulo CHANGES
380 -1: rpluem: This change is still disputed. See
381 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
383 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
384 compiled by the build compiler instead of the host compiler.
385 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

393 Moved fixing of shebang to separate target so that it is
394 no longer executed by default and all CGIs remain inactive.

398 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
401 This commit is essentially deciding that an httpd install on
402 Windows now has printenv/testcgi written in 2 more languages.
403 To the extent that the usefulness is that it shows how to make scripts
404 of these types executable by httpd, I believe that the documentation
405 is the proper place to solve that. To the extent that the usefullness
406 is to show how to implement a CGI in these particular languages, I believe
407 that the httpd distribution and documentation in general is not the
408 place for that. Historically these types of scripts have caused problems
409 for downstream vendorsas well as newbies (and sometimes the intersection
410 of those two groups) who don't understand that these are information leaks
411 once they are enabled, and the subtlety of the way they are disabled ("Apache
412 messed up the first line; let me fix that") contributes to that.
413 fuankg notes: I've just added a big warning to all CGI scripts which should now
414 make absolutely clear that these CGIs are for testing purpose only - so those
415 who enable those scripts with inserting the right shebang should be 100% aware
416 of any risks (this should cover your last point).
417 jim: trawick, does the above address your concerns?
418 trawick: to some extent (somebody reading the script gets an idea)
419 Why isn't the configuration requirement documented instead
420 of described indirectly in a sample?
421 Why are these new samples added to the install without three
422 votes? (I didn't veto it; put your name next to the two
423 existing ones and I'll be satisified that enough people
424 considered this addition as an appropriate solution for a
425 real httpd usability problem.)
426 wrowe: I'd agree with trawick, and suggest that these scripts can begin
427 their life somewhere in the manual/ tree. This really seems like
428 the place where /usr/share/httpd/examples/ would be useful, but
429 there isn't an ordinary directory for that. Since we want none
430 of the scripts to function 'out of the box', what about a new
431 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
