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

233 2.4.x patch: trunk works (modulo CHANGES)

239 trunk patch: http://svn.apache.org/r1756553
240 2.4.x patch: trunk works (modulo CHANGES)
244 PATCHES/ISSUES THAT ARE BEING WORKED
246 *) http: Don't remove the Content-Length of zero from a HEAD response if
247 it comes from an origin server, module or script. Allow the previous
248 behaviour (for legacy/buggy modules only, not origin) by also backporting
249 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
250 comes for free with the same commit).
251 trunk patch: http://svn.apache.org/r1554303
252 http://svn.apache.org/r1678215
253 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
255 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
256 ints added at the end of core_server_config, the proposed merge
257 does a minor bump only.
258 minfrin: Two new directives need to be documented.
260 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
261 fetching the request body, so to minimize the delay between it is supposed
262 to be alive and the first bytes sent: this is a best effort to prevent the
263 backend from closing because of idle or keepalive timeout in the meantime.
264 Also, handle a new "proxy-flushall" environment variable which allows to
265 flush any forwarded body data immediately. PR 56541+37920.
266 trunk patch: http://svn.apache.org/r1656259
267 http://svn.apache.org/r1656359 (CHANGES entry)
268 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
270 -0: jim: This seems to be a hit to normal performance, to handle an
271 error and/or non-normal condition. The pre-fetch is
272 expensive, and is always done, even before we know that
273 the backend is available to rec' it. I understand the
274 error described, but is the fix actually worth it (plus
275 it seems to allow for a DDoS vector).
276 ylavic: It seems to me that the problem is real since we reuse the
277 connection before prefetching 16K (either controlled by the
278 client, or by an input filter), we currently always prefetch
279 these bytes already. Regarding performance I don't see any
280 difference (more cycles) compared with the current code.
281 However I think I failed to rebuild the header_brigade when
282 the proxy loop is retried (ping), so I need to rework this.
283 Do you think we'd better remove the prefetch, or maybe just
284 make it nonblocking (by default)?
285 jim: Non-blocking seems the best way to handle...
287 * mod_dav: Allow other modules to become providers and add ACLs
288 to the DAV response. Requires a release of apr-util v1.6.
289 trunk patch: http://svn.apache.org/r1748322
290 2.4.x: trunk works modulo CHANGES/MMN
292 rpluem asks: Will this compile with apr-util < v1.6 and keep
293 mod_dav working (without the new features of the patch of course)?
294 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
295 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
296 minfrin: Yes, as you can see in the patch everything applies only
297 if APR_XML_X2T_PARSED is defined, and the patch was tested with
298 both apr-util v1.6 and apr-util v1.5.
300 PATCHES/ISSUES THAT ARE STALLED
302 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
303 backport keeps syslog logging as part of httpd core and only adds
304 API to allow other modules to be used for error logging.

316 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
318 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
319 needs 2 args which is not valid in ErrorLog manual)
320 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
321 (sorry, haven't finished reviewing completely)
322 jim: What is the status of this??
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

349 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
351 sf comments: The IdleShutdown logic seems broken. Consider a single
352 active connection that is stalled for 10 seconds. That
353 connection will be broken after GracefulShutdownTimeout.
354 A better logic would be to check if there is any open
355 connection that is not in keep-alive state.
357 * mod_journald: Add new module mod_journald to log error logs into journald.
358 This patch needs changes done in mod_systemd patch (already

382 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
383 2.4.x patch: trunk patch works modulo CHANGES

388 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
389 compiled by the build compiler instead of the host compiler.
390 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

403 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
406 This commit is essentially deciding that an httpd install on
407 Windows now has printenv/testcgi written in 2 more languages.
408 To the extent that the usefulness is that it shows how to make scripts
409 of these types executable by httpd, I believe that the documentation
410 is the proper place to solve that. To the extent that the usefullness
411 is to show how to implement a CGI in these particular languages, I believe
412 that the httpd distribution and documentation in general is not the
413 place for that. Historically these types of scripts have caused problems
414 for downstream vendorsas well as newbies (and sometimes the intersection
415 of those two groups) who don't understand that these are information leaks
416 once they are enabled, and the subtlety of the way they are disabled ("Apache
417 messed up the first line; let me fix that") contributes to that.
418 fuankg notes: I've just added a big warning to all CGI scripts which should now
419 make absolutely clear that these CGIs are for testing purpose only - so those
420 who enable those scripts with inserting the right shebang should be 100% aware
421 of any risks (this should cover your last point).
422 jim: trawick, does the above address your concerns?
423 trawick: to some extent (somebody reading the script gets an idea)
424 Why isn't the configuration requirement documented instead
425 of described indirectly in a sample?
426 Why are these new samples added to the install without three
427 votes? (I didn't veto it; put your name next to the two
428 existing ones and I'll be satisified that enough people
429 considered this addition as an appropriate solution for a
430 real httpd usability problem.)
431 wrowe: I'd agree with trawick, and suggest that these scripts can begin
432 their life somewhere in the manual/ tree. This really seems like
433 the place where /usr/share/httpd/examples/ would be useful, but
434 there isn't an ordinary directory for that. Since we want none
435 of the scripts to function 'out of the box', what about a new
436 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
439 * core: block Define and Undefine in vhost and directory context. Because
440 it is EXEC_ON_READ, it "breaks out" of these contexts anyway.
441 trunk patch: http://svn.apache.org/r1656063
442 http://svn.apache.org/r1656122
443 2.4.x patch: http://people.apache.org/~covener/patches/2.4.x-define-limits.diff
444 +1: covener (I need to review the docs manually in this area)
445 -1: wrowe (blocking will break "working" .conf files on a subversion update
446 meant to pick up security fixes. "Alerting" I would agree to.)
