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.

144 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
147 *) http: Don't remove the Content-Length of zero from a HEAD response if
148 it comes from an origin server, module or script. Allow the previous
149 behaviour (for legacy/buggy modules only, not origin) by also backporting
150 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
151 comes for free with the same commit).

154 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
156 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
157 ints added at the end of core_server_config, the proposed merge
158 does a minor bump only.
159 minfrin: Two new directives need to be documented.

217 2.4.x patch: trunk works (module CHANGES)
219 ylavic: while at it, I also included r1678763 which is only an
220 optimization, but allows to keep code in sync with trunk.

293 PATCHES/ISSUES THAT ARE BEING WORKED
295 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
296 fetching the request body, so to minimize the delay between it is supposed
297 to be alive and the first bytes sent: this is a best effort to prevent the
298 backend from closing because of idle or keepalive timeout in the meantime.
299 Also, handle a new "proxy-flushall" environment variable which allows to
300 flush any forwarded body data immediately. PR 56541+37920.
301 trunk patch: http://svn.apache.org/r1656259
302 http://svn.apache.org/r1656359 (CHANGES entry)
303 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
305 -0: jim: This seems to be a hit to normal performance, to handle an
306 error and/or non-normal condition. The pre-fetch is
307 expensive, and is always done, even before we know that
308 the backend is available to rec' it. I understand the
309 error described, but is the fix actually worth it (plus
310 it seems to allow for a DDoS vector).
311 ylavic: It seems to me that the problem is real since we reuse the
312 connection before prefetching 16K (either controlled by the
313 client, or by an input filter), we currently always prefetch
314 these bytes already. Regarding performance I don't see any
315 difference (more cycles) compared with the current code.
316 However I think I failed to rebuild the header_brigade when
317 the proxy loop is retried (ping), so I need to rework this.
318 Do you think we'd better remove the prefetch, or maybe just
319 make it nonblocking (by default)?
320 jim: Non-blocking seems the best way to handle...
322 PATCHES/ISSUES THAT ARE STALLED
324 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
325 and ProxyMatch section to distinguish between normal workers and workers
326 with regex substitutions in the name. Implement handling of such workers
327 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
328 matched and used for request. PR 43513.
329 trunk patch: http://svn.apache.org/r1609680
330 http://svn.apache.org/r1609688
331 http://svn.apache.org/r1641381
332 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
333 Also added missing r1609688 to the patchset.
334 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
336 -0: covener tried to review this one in Austin with Jeff. Does the added match function
337 really cover a very narrow set of parameters with the way it skips over backreferences?
338 Also, why a new API vs. just setting the field inline?
340 * mod_systemd: New module, for integration with systemd on Linux.
341 trunk patch: http://svn.apache.org/r1393976

362 * mod_proxy: Ensure network errors detected by the proxy are returned as
363 504 Gateway Timout as opposed to 502 Bad Gateway
364 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
365 2.4.x patch: trunk patch works modulo CHANGES
367 -1: rpluem: This change is still disputed. See
368 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
370 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
371 compiled by the build compiler instead of the host compiler.
372 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

385 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
388 This commit is essentially deciding that an httpd install on
389 Windows now has printenv/testcgi written in 2 more languages.
390 To the extent that the usefulness is that it shows how to make scripts
391 of these types executable by httpd, I believe that the documentation
392 is the proper place to solve that. To the extent that the usefullness
393 is to show how to implement a CGI in these particular languages, I believe
394 that the httpd distribution and documentation in general is not the
395 place for that. Historically these types of scripts have caused problems
396 for downstream vendorsas well as newbies (and sometimes the intersection
397 of those two groups) who don't understand that these are information leaks
398 once they are enabled, and the subtlety of the way they are disabled ("Apache
399 messed up the first line; let me fix that") contributes to that.
400 fuankg notes: I've just added a big warning to all CGI scripts which should now
401 make absolutely clear that these CGIs are for testing purpose only - so those
402 who enable those scripts with inserting the right shebang should be 100% aware
403 of any risks (this should cover your last point).
404 jim: trawick, does the above address your concerns?
405 trawick: to some extent (somebody reading the script gets an idea)
406 Why isn't the configuration requirement documented instead
407 of described indirectly in a sample?
408 Why are these new samples added to the install without three
409 votes? (I didn't veto it; put your name next to the two
410 existing ones and I'll be satisified that enough people
411 considered this addition as an appropriate solution for a
412 real httpd usability problem.)
413 wrowe: I'd agree with trawick, and suggest that these scripts can begin
414 their life somewhere in the manual/ tree. This really seems like
415 the place where /usr/share/httpd/examples/ would be useful, but
416 there isn't an ordinary directory for that. Since we want none
417 of the scripts to function 'out of the box', what about a new
418 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
