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:
105 . non-Unix, single-platform code
107 RELEASE SHOWSTOPPERS:
110 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
111 [ start all new proposals below, under PATCHES PROPOSED. ]
115 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
116 [ New proposals should be added at the end of the list ]
118 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
119 backport keeps syslog logging as part of httpd core and only adds
120 API to allow other modules to be used for error logging.

152 it comes from an origin server, module or script. Allow the previous
153 behaviour (for legacy/buggy modules only, not origin) by also backporting

160 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
161 ints added at the end of core_server_config, the proposed merge
162 does a minor bump only.

272 2.4.x patch: trunk works
276 PATCHES/ISSUES THAT ARE BEING WORKED
278 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
279 fetching the request body, so to minimize the delay between it is supposed
280 to be alive and the first bytes sent: this is a best effort to prevent the
281 backend from closing because of idle or keepalive timeout in the meantime.
282 Also, handle a new "proxy-flushall" environment variable which allows to
283 flush any forwarded body data immediately. PR 56541+37920.
284 trunk patch: http://svn.apache.org/r1656259
285 http://svn.apache.org/r1656359 (CHANGES entry)
286 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
288 -0: jim: This seems to be a hit to normal performance, to handle an
289 error and/or non-normal condition. The pre-fetch is
290 expensive, and is always done, even before we know that
291 the backend is available to rec' it. I understand the
292 error described, but is the fix actually worth it (plus
293 it seems to allow for a DDoS vector).
294 ylavic: It seems to me that the problem is real since we reuse the
295 connection before prefetching 16K (either controlled by the
296 client, or by an input filter), we currently always prefetch
297 these bytes already. Regarding performance I don't see any
298 difference (more cycles) compared with the current code.
299 However I think I failed to rebuild the header_brigade when
300 the proxy loop is retried (ping), so I need to rework this.
301 Do you think we'd better remove the prefetch, or maybe just
302 make it nonblocking (by default)?
303 jim: Non-blocking seems the best way to handle...
305 PATCHES/ISSUES THAT ARE STALLED
307 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
308 and ProxyMatch section to distinguish between normal workers and workers
309 with regex substitutions in the name. Implement handling of such workers
310 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
311 matched and used for request. PR 43513.
312 trunk patch: http://svn.apache.org/r1609680
313 http://svn.apache.org/r1609688
314 http://svn.apache.org/r1641381
315 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
316 Also added missing r1609688 to the patchset.
317 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
319 -0: covener tried to review this one in Austin with Jeff. Does the added match function
320 really cover a very narrow set of parameters with the way it skips over backreferences?
321 Also, why a new API vs. just setting the field inline?
323 * mod_systemd: New module, for integration with systemd on Linux.

346 504 Gateway Timout as opposed to 502 Bad Gateway
347 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
348 2.4.x patch: trunk patch works modulo CHANGES
350 -1: rpluem: This change is still disputed. See
351 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
353 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
354 compiled by the build compiler instead of the host compiler.
355 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

364 no longer executed by default and all CGIs remain inactive.

368 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
371 This commit is essentially deciding that an httpd install on
372 Windows now has printenv/testcgi written in 2 more languages.
373 To the extent that the usefulness is that it shows how to make scripts
374 of these types executable by httpd, I believe that the documentation
375 is the proper place to solve that. To the extent that the usefullness
376 is to show how to implement a CGI in these particular languages, I believe
377 that the httpd distribution and documentation in general is not the
378 place for that. Historically these types of scripts have caused problems
379 for downstream vendorsas well as newbies (and sometimes the intersection
380 of those two groups) who don't understand that these are information leaks
381 once they are enabled, and the subtlety of the way they are disabled ("Apache
382 messed up the first line; let me fix that") contributes to that.
383 fuankg notes: I've just added a big warning to all CGI scripts which should now
384 make absolutely clear that these CGIs are for testing purpose only - so those
385 who enable those scripts with inserting the right shebang should be 100% aware
386 of any risks (this should cover your last point).
387 jim: trawick, does the above address your concerns?
388 trawick: to some extent (somebody reading the script gets an idea)
389 Why isn't the configuration requirement documented instead
390 of described indirectly in a sample?
391 Why are these new samples added to the install without three
392 votes? (I didn't veto it; put your name next to the two
393 existing ones and I'll be satisified that enough people
394 considered this addition as an appropriate solution for a
395 real httpd usability problem.)
396 wrowe: I'd agree with trawick, and suggest that these scripts can begin
397 their life somewhere in the manual/ tree. This really seems like
398 the place where /usr/share/httpd/examples/ would be useful, but
399 there isn't an ordinary directory for that. Since we want none
400 of the scripts to function 'out of the box', what about a new
401 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
