92 CURRENT RELEASE NOTES:
94 * Forward binary compatibility is expected of Apache 2.4.x releases, such
95 that no MMN major number changes will occur after 2.4.1. Such changes can
96 only be made in the trunk.
98 * All commits to branches/2.4.x must be reflected in SVN trunk,
99 as well, if they apply. Logical progression is commit to trunk
100 then merge into branches/2.4.x, as applicable.
102 * Current exceptions for RTC for this branch:
107 . non-Unix, single-platform code

175 ylavic: Needs r1732957 for empty APLOGNO()s.
176 ylavic: Looks like the changes on struct proxy_worker_shared would break
177 startup with "BalancerPersist on" due to the strict checks on

180 *) Use pre_connection hook in event.c to properly setup connection state
181 of slave connections (eliminates hacks in mod_http2).

197 2.4.x patch: trunk above works

232 2.4.x patch: http://home.apache.org/~ylavic/patches/httpd-2.4.x-exit_with_error_on_mpm_failure.patch
236 PATCHES/ISSUES THAT ARE BEING WORKED
238 *) http: Don't remove the Content-Length of zero from a HEAD response if
239 it comes from an origin server, module or script. Allow the previous
240 behaviour (for legacy/buggy modules only, not origin) by also backporting
241 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
242 comes for free with the same commit).
243 trunk patch: http://svn.apache.org/r1554303
244 http://svn.apache.org/r1678215
245 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
247 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
248 ints added at the end of core_server_config, the proposed merge
249 does a minor bump only.
250 minfrin: Two new directives need to be documented.
252 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
253 fetching the request body, so to minimize the delay between it is supposed
254 to be alive and the first bytes sent: this is a best effort to prevent the
255 backend from closing because of idle or keepalive timeout in the meantime.
256 Also, handle a new "proxy-flushall" environment variable which allows to
257 flush any forwarded body data immediately. PR 56541+37920.
258 trunk patch: http://svn.apache.org/r1656259
259 http://svn.apache.org/r1656359 (CHANGES entry)
260 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
262 -0: jim: This seems to be a hit to normal performance, to handle an
263 error and/or non-normal condition. The pre-fetch is
264 expensive, and is always done, even before we know that
265 the backend is available to rec' it. I understand the
266 error described, but is the fix actually worth it (plus
267 it seems to allow for a DDoS vector).
268 ylavic: It seems to me that the problem is real since we reuse the
269 connection before prefetching 16K (either controlled by the
270 client, or by an input filter), we currently always prefetch
271 these bytes already. Regarding performance I don't see any
272 difference (more cycles) compared with the current code.
273 However I think I failed to rebuild the header_brigade when
274 the proxy loop is retried (ping), so I need to rework this.
275 Do you think we'd better remove the prefetch, or maybe just
276 make it nonblocking (by default)?
277 jim: Non-blocking seems the best way to handle...
279 PATCHES/ISSUES THAT ARE STALLED
281 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
282 backport keeps syslog logging as part of httpd core and only adds
283 API to allow other modules to be used for error logging.
284 trunk patch: http://svn.apache.org/r1525597
285 http://svn.apache.org/r1525664

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

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

347 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
349 * core: Add support for systemd socket activation.

360 504 Gateway Timout as opposed to 502 Bad Gateway
361 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
362 2.4.x patch: trunk patch works modulo CHANGES
364 -1: rpluem: This change is still disputed. See

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

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

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