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

245 trunk patch: http://svn.apache.org/r1756553
246 2.4.x patch: trunk works (modulo CHANGES)
250 PATCHES/ISSUES THAT ARE BEING WORKED
252 *) http: Don't remove the Content-Length of zero from a HEAD response if
253 it comes from an origin server, module or script. Allow the previous
254 behaviour (for legacy/buggy modules only, not origin) by also backporting
255 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
256 comes for free with the same commit).
257 trunk patch: http://svn.apache.org/r1554303
258 http://svn.apache.org/r1678215
259 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
261 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
262 ints added at the end of core_server_config, the proposed merge
263 does a minor bump only.
264 minfrin: Two new directives need to be documented.
266 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
267 fetching the request body, so to minimize the delay between it is supposed
268 to be alive and the first bytes sent: this is a best effort to prevent the
269 backend from closing because of idle or keepalive timeout in the meantime.
270 Also, handle a new "proxy-flushall" environment variable which allows to
271 flush any forwarded body data immediately. PR 56541+37920.
272 trunk patch: http://svn.apache.org/r1656259
273 http://svn.apache.org/r1656359 (CHANGES entry)
274 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
276 -0: jim: This seems to be a hit to normal performance, to handle an
277 error and/or non-normal condition. The pre-fetch is
278 expensive, and is always done, even before we know that
279 the backend is available to rec' it. I understand the
280 error described, but is the fix actually worth it (plus
281 it seems to allow for a DDoS vector).
282 ylavic: It seems to me that the problem is real since we reuse the
283 connection before prefetching 16K (either controlled by the
284 client, or by an input filter), we currently always prefetch
285 these bytes already. Regarding performance I don't see any
286 difference (more cycles) compared with the current code.
287 However I think I failed to rebuild the header_brigade when
288 the proxy loop is retried (ping), so I need to rework this.
289 Do you think we'd better remove the prefetch, or maybe just
290 make it nonblocking (by default)?
291 jim: Non-blocking seems the best way to handle...
293 * mod_dav: Allow other modules to become providers and add ACLs
294 to the DAV response. Requires a release of apr-util v1.6.
295 trunk patch: http://svn.apache.org/r1748322
296 2.4.x: trunk works modulo CHANGES/MMN
298 rpluem asks: Will this compile with apr-util < v1.6 and keep
299 mod_dav working (without the new features of the patch of course)?
300 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
301 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
302 minfrin: Yes, as you can see in the patch everything applies only
303 if APR_XML_X2T_PARSED is defined, and the patch was tested with
304 both apr-util v1.6 and apr-util v1.5.
306 PATCHES/ISSUES THAT ARE STALLED
308 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
309 backport keeps syslog logging as part of httpd core and only adds
310 API to allow other modules to be used for error logging.
311 trunk patch: http://svn.apache.org/r1525597

322 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
324 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
325 needs 2 args which is not valid in ErrorLog manual)
326 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
327 (sorry, haven't finished reviewing completely)
328 jim: What is the status of this??
330 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
331 and ProxyMatch section to distinguish between normal workers and workers
332 with regex substitutions in the name. Implement handling of such workers
333 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
334 matched and used for request. PR 43513.
335 trunk patch: http://svn.apache.org/r1609680
336 http://svn.apache.org/r1609688
337 http://svn.apache.org/r1641381
338 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
339 Also added missing r1609688 to the patchset.
340 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
342 -0: covener tried to review this one in Austin with Jeff. Does the added match function
343 really cover a very narrow set of parameters with the way it skips over backreferences?
344 Also, why a new API vs. just setting the field inline?
346 * mod_systemd: New module, for integration with systemd on Linux.

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

373 jkaluza: No, that patch is not committed yet. It is in STALLED section.
374 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch

388 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
389 2.4.x patch: trunk patch works modulo CHANGES
391 -1: rpluem: This change is still disputed. See

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

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

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

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

448 http://svn.apache.org/r1656122
