97 CURRENT RELEASE NOTES:
99 * Forward binary compatibility is expected of Apache 2.4.x releases, such
100 that no MMN major number changes will occur after 2.4.1. Such changes can
101 only be made in the trunk.
103 * All commits to branches/2.4.x must be reflected in SVN trunk,
104 as well, if they apply. Logical progression is commit to trunk
105 then merge into branches/2.4.x, as applicable.
107 * Current exceptions for RTC for this branch:
112 . non-Unix, single-platform code

211 trunk patch: http://svn.apache.org/r1753315
212 http://svn.apache.org/r1753316
213 2.4.x patch: http://home.apache.org/~jchampion/patches/2.4.x-autoconf-cleanup.patch
214 (combines both patches and corrects for differences in the
215 AC_CONFIG_FILES list)
217 ylavic: some conflicts with r1753315 in 2.4.x's configure.in.
218 jchampion: added a 2.4.x backport patch.
220 *) mod_ssl: Fix quick renegotiation (OptRenegotiaton) with no intermediate
221 in the client certificate chain. PR 55786.

234 *) mod_proxy_{http,ajp,fcgi}: don't reuse backend connections with data
235 available before the request is sent. PR 57832.
236 This also backports deprecation of ap_proxy_ssl_connection_cleanup() and
237 newly introduced proxy_conn->tmp_bb's usage in proxy code (both almost
238 related and immediate/simple follow ups, merge simplified by doing so).
239 trunk patch: http://svn.apache.org/r1750392

249 *) mod_proxy_hcheck: Add missing copy of hcuri and hcexpr ftom the worker to
250 the health check worker.
251 Trunk version of patch:
252 http://svn.apache.org/r1757662
253 Backport version for 2.4.x of patch:
254 Trunk version of patch works
255 CHANGES in http://svn.apache.org/r1757663
258 PATCHES/ISSUES THAT ARE BEING WORKED
260 *) http: Don't remove the Content-Length of zero from a HEAD response if
261 it comes from an origin server, module or script. Allow the previous
262 behaviour (for legacy/buggy modules only, not origin) by also backporting
263 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
264 comes for free with the same commit).
265 trunk patch: http://svn.apache.org/r1554303
266 http://svn.apache.org/r1678215
267 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
269 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
270 ints added at the end of core_server_config, the proposed merge
271 does a minor bump only.
272 minfrin: Two new directives need to be documented.
274 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
275 fetching the request body, so to minimize the delay between it is supposed
276 to be alive and the first bytes sent: this is a best effort to prevent the
277 backend from closing because of idle or keepalive timeout in the meantime.
278 Also, handle a new "proxy-flushall" environment variable which allows to
279 flush any forwarded body data immediately. PR 56541+37920.
280 trunk patch: http://svn.apache.org/r1656259
281 http://svn.apache.org/r1656359 (CHANGES entry)
282 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
284 -0: jim: This seems to be a hit to normal performance, to handle an
285 error and/or non-normal condition. The pre-fetch is
286 expensive, and is always done, even before we know that
287 the backend is available to rec' it. I understand the
288 error described, but is the fix actually worth it (plus
289 it seems to allow for a DDoS vector).
290 ylavic: It seems to me that the problem is real since we reuse the
291 connection before prefetching 16K (either controlled by the
292 client, or by an input filter), we currently always prefetch
293 these bytes already. Regarding performance I don't see any
294 difference (more cycles) compared with the current code.
295 However I think I failed to rebuild the header_brigade when
296 the proxy loop is retried (ping), so I need to rework this.
297 Do you think we'd better remove the prefetch, or maybe just
298 make it nonblocking (by default)?
299 jim: Non-blocking seems the best way to handle...
301 * mod_dav: Allow other modules to become providers and add ACLs
302 to the DAV response. Requires a release of apr-util v1.6.
303 trunk patch: http://svn.apache.org/r1748322
304 2.4.x: trunk works modulo CHANGES/MMN
306 rpluem asks: Will this compile with apr-util < v1.6 and keep
307 mod_dav working (without the new features of the patch of course)?
308 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
309 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
310 minfrin: Yes, as you can see in the patch everything applies only
311 if APR_XML_X2T_PARSED is defined, and the patch was tested with
312 both apr-util v1.6 and apr-util v1.5.
314 PATCHES/ISSUES THAT ARE STALLED
316 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
317 backport keeps syslog logging as part of httpd core and only adds
318 API to allow other modules to be used for error logging.
319 trunk patch: http://svn.apache.org/r1525597

330 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
332 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
333 needs 2 args which is not valid in ErrorLog manual)
334 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
335 (sorry, haven't finished reviewing completely)
336 jim: What is the status of this??
338 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
339 and ProxyMatch section to distinguish between normal workers and workers
340 with regex substitutions in the name. Implement handling of such workers
341 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
342 matched and used for request. PR 43513.
343 trunk patch: http://svn.apache.org/r1609680
344 http://svn.apache.org/r1609688
345 http://svn.apache.org/r1641381
346 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
347 Also added missing r1609688 to the patchset.
348 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
350 -0: covener tried to review this one in Austin with Jeff. Does the added match function
351 really cover a very narrow set of parameters with the way it skips over backreferences?
352 Also, why a new API vs. just setting the field inline?
354 * mod_systemd: New module, for integration with systemd on Linux.
355 trunk patch: http://svn.apache.org/r1393976

363 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
365 sf comments: The IdleShutdown logic seems broken. Consider a single
366 active connection that is stalled for 10 seconds. That
367 connection will be broken after GracefulShutdownTimeout.
368 A better logic would be to check if there is any open
369 connection that is not in keep-alive state.
371 * mod_journald: Add new module mod_journald to log error logs into journald.
372 This patch needs changes done in mod_systemd patch (already

378 rjung, minfrin: Not understanding "This patch needs changes done in
379 mod_systemd patch", am I right in understanding this patch is
381 jkaluza: No, that patch is not committed yet. It is in STALLED section.
382 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch

395 504 Gateway Timout as opposed to 502 Bad Gateway
396 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
397 2.4.x patch: trunk patch works modulo CHANGES
399 -1: rpluem: This change is still disputed. See
400 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
402 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
403 compiled by the build compiler instead of the host compiler.
404 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

409 fuankg: on hold until we agree for a better and more simple solution ...

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

417 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
420 This commit is essentially deciding that an httpd install on
421 Windows now has printenv/testcgi written in 2 more languages.
422 To the extent that the usefulness is that it shows how to make scripts
423 of these types executable by httpd, I believe that the documentation
424 is the proper place to solve that. To the extent that the usefullness
425 is to show how to implement a CGI in these particular languages, I believe
426 that the httpd distribution and documentation in general is not the
427 place for that. Historically these types of scripts have caused problems
428 for downstream vendorsas well as newbies (and sometimes the intersection
429 of those two groups) who don't understand that these are information leaks
430 once they are enabled, and the subtlety of the way they are disabled ("Apache
431 messed up the first line; let me fix that") contributes to that.
432 fuankg notes: I've just added a big warning to all CGI scripts which should now
433 make absolutely clear that these CGIs are for testing purpose only - so those
434 who enable those scripts with inserting the right shebang should be 100% aware
435 of any risks (this should cover your last point).
436 jim: trawick, does the above address your concerns?
437 trawick: to some extent (somebody reading the script gets an idea)
438 Why isn't the configuration requirement documented instead
439 of described indirectly in a sample?
440 Why are these new samples added to the install without three
441 votes? (I didn't veto it; put your name next to the two
442 existing ones and I'll be satisified that enough people
443 considered this addition as an appropriate solution for a
444 real httpd usability problem.)
445 wrowe: I'd agree with trawick, and suggest that these scripts can begin
446 their life somewhere in the manual/ tree. This really seems like
447 the place where /usr/share/httpd/examples/ would be useful, but
448 there isn't an ordinary directory for that. Since we want none
449 of the scripts to function 'out of the box', what about a new
450 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
453 * core: block Define and Undefine in vhost and directory context. Because
454 it is EXEC_ON_READ, it "breaks out" of these contexts anyway.
455 trunk patch: http://svn.apache.org/r1656063

457 2.4.x patch: http://people.apache.org/~covener/patches/2.4.x-define-limits.diff
458 +1: covener (I need to review the docs manually in this area)
459 -1: wrowe (blocking will break "working" .conf files on a subversion update
460 meant to pick up security fixes. "Alerting" I would agree to.)
