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

136 + http://svn.apache.org/r1729374
137 +1: covener, jim, ylavic

150 [ New proposals should be added at the end of the list ]
152 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias

165 trunk patch: http://svn.apache.org/r1711479
166 2.4.x patch: trunk works
168 minfrin: Needs extra parens to suppress a warning:
169 prefork.c:1319:16: note: place parentheses around the assignment
170 to silence this warning
171 jailletc36: This has been done in r1711919
172 ylavic: Also, I don't think the changes on worker/event are needed,
173 only prefork requires the accept mutex in ONE_PROCESS mode.
175 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
176 SSLCryptoDevice does not get unregistered because of non-zero refcount
177 during the mod_ssl unload happening on httpd startup.
178 trunk patch: http://svn.apache.org/r1720129
179 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
181 ylavic: +1 with r1723295 (likewise for ecparams).
183 *) mod_cache_socache: Fix a possible cached entity body corruption when it
184 is received from an origin server in multiple batches and forwarded by

206 Trunk version of patch:
207 http://svn.apache.org/r1588330
208 Trunk patch applies clean, modulo CHANGES
211 PATCHES/ISSUES THAT ARE BEING WORKED
213 *) http: Don't remove the Content-Length of zero from a HEAD response if
214 it comes from an origin server, module or script. Allow the previous
215 behaviour (for legacy/buggy modules only, not origin) by also backporting
216 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
217 comes for free with the same commit).
218 trunk patch: http://svn.apache.org/r1554303
219 http://svn.apache.org/r1678215
220 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
222 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
223 ints added at the end of core_server_config, the proposed merge
224 does a minor bump only.
225 minfrin: Two new directives need to be documented.
227 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
228 fetching the request body, so to minimize the delay between it is supposed
229 to be alive and the first bytes sent: this is a best effort to prevent the
230 backend from closing because of idle or keepalive timeout in the meantime.
231 Also, handle a new "proxy-flushall" environment variable which allows to
232 flush any forwarded body data immediately. PR 56541+37920.
233 trunk patch: http://svn.apache.org/r1656259
234 http://svn.apache.org/r1656359 (CHANGES entry)
235 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
237 -0: jim: This seems to be a hit to normal performance, to handle an
238 error and/or non-normal condition. The pre-fetch is
239 expensive, and is always done, even before we know that
240 the backend is available to rec' it. I understand the
241 error described, but is the fix actually worth it (plus
242 it seems to allow for a DDoS vector).
243 ylavic: It seems to me that the problem is real since we reuse the
244 connection before prefetching 16K (either controlled by the
245 client, or by an input filter), we currently always prefetch
246 these bytes already. Regarding performance I don't see any
247 difference (more cycles) compared with the current code.
248 However I think I failed to rebuild the header_brigade when
249 the proxy loop is retried (ping), so I need to rework this.
250 Do you think we'd better remove the prefetch, or maybe just
251 make it nonblocking (by default)?
252 jim: Non-blocking seems the best way to handle...
254 PATCHES/ISSUES THAT ARE STALLED
256 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
257 backport keeps syslog logging as part of httpd core and only adds
258 API to allow other modules to be used for error logging.
259 trunk patch: http://svn.apache.org/r1525597
260 http://svn.apache.org/r1525664
261 http://svn.apache.org/r1525845
262 http://svn.apache.org/r1527003

268 http://svn.apache.org/r1544156
269 http://svn.apache.org/r1626978
270 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
272 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
273 needs 2 args which is not valid in ErrorLog manual)
274 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
275 (sorry, haven't finished reviewing completely)
276 jim: What is the status of this??
278 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
279 and ProxyMatch section to distinguish between normal workers and workers
280 with regex substitutions in the name. Implement handling of such workers
281 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
282 matched and used for request. PR 43513.
283 trunk patch: http://svn.apache.org/r1609680
284 http://svn.apache.org/r1609688
285 http://svn.apache.org/r1641381
286 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
287 Also added missing r1609688 to the patchset.
288 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
290 -0: covener tried to review this one in Austin with Jeff. Does the added match function
291 really cover a very narrow set of parameters with the way it skips over backreferences?
292 Also, why a new API vs. just setting the field inline?
294 * mod_systemd: New module, for integration with systemd on Linux.
295 trunk patch: http://svn.apache.org/r1393976
296 http://svn.apache.org/r1393997

303 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
306 * mod_journald: Add new module mod_journald to log error logs into journald.
307 This patch needs changes done in mod_systemd patch (already
309 trunk patch: http://svn.apache.org/r1610339
310 http://svn.apache.org/r1621806
311 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
313 rjung, minfrin: Not understanding "This patch needs changes done in
314 mod_systemd patch", am I right in understanding this patch is
316 jkaluza: No, that patch is not committed yet. It is in STALLED section.
317 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch

329 * mod_proxy: Ensure network errors detected by the proxy are returned as
330 504 Gateway Timout as opposed to 502 Bad Gateway
331 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
332 2.4.x patch: trunk patch works modulo CHANGES
334 -1: rpluem: This change is still disputed. See

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

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

352 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
355 This commit is essentially deciding that an httpd install on
356 Windows now has printenv/testcgi written in 2 more languages.
357 To the extent that the usefulness is that it shows how to make scripts
358 of these types executable by httpd, I believe that the documentation
359 is the proper place to solve that. To the extent that the usefullness
360 is to show how to implement a CGI in these particular languages, I believe
361 that the httpd distribution and documentation in general is not the
362 place for that. Historically these types of scripts have caused problems
363 for downstream vendorsas well as newbies (and sometimes the intersection
364 of those two groups) who don't understand that these are information leaks
365 once they are enabled, and the subtlety of the way they are disabled ("Apache
366 messed up the first line; let me fix that") contributes to that.
367 fuankg notes: I've just added a big warning to all CGI scripts which should now
368 make absolutely clear that these CGIs are for testing purpose only - so those
369 who enable those scripts with inserting the right shebang should be 100% aware
370 of any risks (this should cover your last point).
371 jim: trawick, does the above address your concerns?
372 trawick: to some extent (somebody reading the script gets an idea)
373 Why isn't the configuration requirement documented instead
374 of described indirectly in a sample?
375 Why are these new samples added to the install without three
376 votes? (I didn't veto it; put your name next to the two
377 existing ones and I'll be satisified that enough people
378 considered this addition as an appropriate solution for a
379 real httpd usability problem.)
380 wrowe: I'd agree with trawick, and suggest that these scripts can begin
381 their life somewhere in the manual/ tree. This really seems like
382 the place where /usr/share/httpd/examples/ would be useful, but
383 there isn't an ordinary directory for that. Since we want none
384 of the scripts to function 'out of the box', what about a new
385 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
