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

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

304 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
306 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
307 needs 2 args which is not valid in ErrorLog manual)
308 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
309 (sorry, haven't finished reviewing completely)
310 jim: What is the status of this??
312 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
313 and ProxyMatch section to distinguish between normal workers and workers
314 with regex substitutions in the name. Implement handling of such workers
315 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
316 matched and used for request. PR 43513.
317 trunk patch: http://svn.apache.org/r1609680
318 http://svn.apache.org/r1609688
319 http://svn.apache.org/r1641381
320 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
321 Also added missing r1609688 to the patchset.
322 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
324 -0: covener tried to review this one in Austin with Jeff. Does the added match function
325 really cover a very narrow set of parameters with the way it skips over backreferences?
326 Also, why a new API vs. just setting the field inline?
328 * mod_systemd: New module, for integration with systemd on Linux.

337 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
339 sf comments: The IdleShutdown logic seems broken. Consider a single
340 active connection that is stalled for 10 seconds. That
341 connection will be broken after GracefulShutdownTimeout.
342 A better logic would be to check if there is any open
343 connection that is not in keep-alive state.
345 * mod_journald: Add new module mod_journald to log error logs into journald.
346 This patch needs changes done in mod_systemd patch (already

369 504 Gateway Timout as opposed to 502 Bad Gateway
370 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
371 2.4.x patch: trunk patch works modulo CHANGES
373 -1: rpluem: This change is still disputed. See
374 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
376 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
377 compiled by the build compiler instead of the host compiler.
378 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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

434 meant to pick up security fixes. "Alerting" I would agree to.)
