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

216 Backport version for 2.4.x of patch:
217 Trunk version of patch works
218 CHANGES in http://svn.apache.org/r1757663
221 PATCHES/ISSUES THAT ARE BEING WORKED
223 *) http: Don't remove the Content-Length of zero from a HEAD response if
224 it comes from an origin server, module or script. Allow the previous
225 behaviour (for legacy/buggy modules only, not origin) by also backporting
226 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
227 comes for free with the same commit).
228 trunk patch: http://svn.apache.org/r1554303
229 http://svn.apache.org/r1678215
230 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
232 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
233 ints added at the end of core_server_config, the proposed merge
234 does a minor bump only.
235 minfrin: Two new directives need to be documented.
237 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
238 fetching the request body, so to minimize the delay between it is supposed
239 to be alive and the first bytes sent: this is a best effort to prevent the
240 backend from closing because of idle or keepalive timeout in the meantime.
241 Also, handle a new "proxy-flushall" environment variable which allows to
242 flush any forwarded body data immediately. PR 56541+37920.
243 trunk patch: http://svn.apache.org/r1656259
244 http://svn.apache.org/r1656359 (CHANGES entry)
245 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
247 -0: jim: This seems to be a hit to normal performance, to handle an
248 error and/or non-normal condition. The pre-fetch is
249 expensive, and is always done, even before we know that
250 the backend is available to rec' it. I understand the
251 error described, but is the fix actually worth it (plus
252 it seems to allow for a DDoS vector).
253 ylavic: It seems to me that the problem is real since we reuse the
254 connection before prefetching 16K (either controlled by the
255 client, or by an input filter), we currently always prefetch
256 these bytes already. Regarding performance I don't see any
257 difference (more cycles) compared with the current code.
258 However I think I failed to rebuild the header_brigade when
259 the proxy loop is retried (ping), so I need to rework this.
260 Do you think we'd better remove the prefetch, or maybe just
261 make it nonblocking (by default)?
262 jim: Non-blocking seems the best way to handle...
264 * mod_dav: Allow other modules to become providers and add ACLs
265 to the DAV response. Requires a release of apr-util v1.6.
266 trunk patch: http://svn.apache.org/r1748322
267 2.4.x: trunk works modulo CHANGES/MMN
269 rpluem asks: Will this compile with apr-util < v1.6 and keep
270 mod_dav working (without the new features of the patch of course)?
271 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
272 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
273 minfrin: Yes, as you can see in the patch everything applies only
274 if APR_XML_X2T_PARSED is defined, and the patch was tested with
275 both apr-util v1.6 and apr-util v1.5.
277 PATCHES/ISSUES THAT ARE STALLED
279 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
280 backport keeps syslog logging as part of httpd core and only adds
281 API to allow other modules to be used for error logging.
282 trunk patch: http://svn.apache.org/r1525597

293 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
295 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
296 needs 2 args which is not valid in ErrorLog manual)
297 trawick: nit: fix "writing" in "/* NULL if we are writing to syslog */"
298 (sorry, haven't finished reviewing completely)
299 jim: What is the status of this??
301 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
302 and ProxyMatch section to distinguish between normal workers and workers
303 with regex substitutions in the name. Implement handling of such workers
304 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
305 matched and used for request. PR 43513.
306 trunk patch: http://svn.apache.org/r1609680
307 http://svn.apache.org/r1609688
308 http://svn.apache.org/r1641381
309 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
310 Also added missing r1609688 to the patchset.
311 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
313 -0: covener tried to review this one in Austin with Jeff. Does the added match function
314 really cover a very narrow set of parameters with the way it skips over backreferences?
315 Also, why a new API vs. just setting the field inline?
317 * mod_systemd: New module, for integration with systemd on Linux.

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

358 504 Gateway Timeout as opposed to 502 Bad Gateway
359 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
360 2.4.x patch: trunk patch works modulo CHANGES
362 -1: rpluem: This change is still disputed. See
363 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
365 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
366 compiled by the build compiler instead of the host compiler.
367 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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

420 2.4.x patch: http://people.apache.org/~covener/patches/2.4.x-define-limits.diff
421 +1: covener (I need to review the docs manually in this area)
422 -1: wrowe (blocking will break "working" .conf files on a subversion update
423 meant to pick up security fixes. "Alerting" I would agree to.)
