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

214 trunk patch: http://svn.apache.org/r1753777
215 2.4.x patch: trunk works
218 PATCHES/ISSUES THAT ARE BEING WORKED
220 *) http: Don't remove the Content-Length of zero from a HEAD response if
221 it comes from an origin server, module or script. Allow the previous
222 behaviour (for legacy/buggy modules only, not origin) by also backporting
223 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
224 comes for free with the same commit).
225 trunk patch: http://svn.apache.org/r1554303
226 http://svn.apache.org/r1678215
227 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
229 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
230 ints added at the end of core_server_config, the proposed merge
231 does a minor bump only.
232 minfrin: Two new directives need to be documented.
234 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
235 fetching the request body, so to minimize the delay between it is supposed
236 to be alive and the first bytes sent: this is a best effort to prevent the
237 backend from closing because of idle or keepalive timeout in the meantime.
238 Also, handle a new "proxy-flushall" environment variable which allows to
239 flush any forwarded body data immediately. PR 56541+37920.
240 trunk patch: http://svn.apache.org/r1656259
241 http://svn.apache.org/r1656359 (CHANGES entry)
242 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
244 -0: jim: This seems to be a hit to normal performance, to handle an
245 error and/or non-normal condition. The pre-fetch is
246 expensive, and is always done, even before we know that
247 the backend is available to rec' it. I understand the
248 error described, but is the fix actually worth it (plus
249 it seems to allow for a DDoS vector).
250 ylavic: It seems to me that the problem is real since we reuse the
251 connection before prefetching 16K (either controlled by the
252 client, or by an input filter), we currently always prefetch
253 these bytes already. Regarding performance I don't see any
254 difference (more cycles) compared with the current code.
255 However I think I failed to rebuild the header_brigade when
256 the proxy loop is retried (ping), so I need to rework this.
257 Do you think we'd better remove the prefetch, or maybe just
258 make it nonblocking (by default)?
259 jim: Non-blocking seems the best way to handle...
261 * mod_dav: Allow other modules to become providers and add ACLs
262 to the DAV response. Requires a release of apr-util v1.6.
263 trunk patch: http://svn.apache.org/r1748322
264 2.4.x: trunk works modulo CHANGES/MMN
266 rpluem asks: Will this compile with apr-util < v1.6 and keep
267 mod_dav working (without the new features of the patch of course)?
268 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
269 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
270 minfrin: Yes, as you can see in the patch everything applies only
271 if APR_XML_X2T_PARSED is defined, and the patch was tested with
272 both apr-util v1.6 and apr-util v1.5.
274 PATCHES/ISSUES THAT ARE STALLED
276 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
277 backport keeps syslog logging as part of httpd core and only adds
278 API to allow other modules to be used for error logging.
279 trunk patch: http://svn.apache.org/r1525597
280 http://svn.apache.org/r1525664
281 http://svn.apache.org/r1525845

289 http://svn.apache.org/r1626978
290 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
292 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
293 needs 2 args which is not valid in ErrorLog manual)
294 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
295 (sorry, haven't finished reviewing completely)
296 jim: What is the status of this??
298 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
299 and ProxyMatch section to distinguish between normal workers and workers
300 with regex substitutions in the name. Implement handling of such workers
301 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
302 matched and used for request. PR 43513.
303 trunk patch: http://svn.apache.org/r1609680
304 http://svn.apache.org/r1609688
305 http://svn.apache.org/r1641381
306 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
307 Also added missing r1609688 to the patchset.
308 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
310 -0: covener tried to review this one in Austin with Jeff. Does the added match function
311 really cover a very narrow set of parameters with the way it skips over backreferences?
312 Also, why a new API vs. just setting the field inline?
314 * mod_systemd: New module, for integration with systemd on Linux.

323 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
325 sf comments: The IdleShutdown logic seems broken. Consider a single
326 active connection that is stalled for 10 seconds. That
327 connection will be broken after GracefulShutdownTimeout.
328 A better logic would be to check if there is any open
329 connection that is not in keep-alive state.
331 * mod_journald: Add new module mod_journald to log error logs into journald.
332 This patch needs changes done in mod_systemd patch (already

339 mod_systemd patch", am I right in understanding this patch is
341 jkaluza: No, that patch is not committed yet. It is in STALLED section.
342 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch

355 504 Gateway Timout as opposed to 502 Bad Gateway
356 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
357 2.4.x patch: trunk patch works modulo CHANGES
359 -1: rpluem: This change is still disputed. See
360 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
362 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
363 compiled by the build compiler instead of the host compiler.
364 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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

418 +1: covener (I need to review the docs manually in this area)
419 -1: wrowe (blocking will break "working" .conf files on a subversion update
420 meant to pick up security fixes. "Alerting" I would agree to.)
