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

131 tested, it is not actually used)
132 2.4.x patch: trunk works
133 +1: jailletc36, covener, jim
135 *) mod_mod_authn_socache: Do not use the magic string "directory". Use the
136 corresponding global variable as in all other places of the module.

138 2.4.x patch: trunk works
139 +1: jailletc36, covener, jim
141 *) mime.types: Add common extension "m4a" for MPEG 4 Audio.
142 As a reference see Wikipedia:
143 https://en.wikipedia.org/wiki/MPEG-4_Part_14#.MP4_versus_.M4A

146 2.4.x patch: trunk works, modulo CHANGES
147 +1: rjung, covener, jim
151 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
152 [ New proposals should be added at the end of the list ]
154 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
155 and Redirect. Limit Redirect expressions to directory (Location) context
156 and redirect statuses (implicit or explicit).
157 trunk patch: http://svn.apache.org/r1653941
158 http://svn.apache.org/r1653978
159 http://svn.apache.org/r1656225
160 http://svn.apache.org/r1686853
161 http://svn.apache.org/r1686856
162 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
165 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
166 its parameter when starting httpd as single process (httpd -X).
167 trunk patch: http://svn.apache.org/r1711479
168 2.4.x patch: trunk works
170 minfrin: Needs extra parens to suppress a warning:
171 prefork.c:1319:16: note: place parentheses around the assignment
172 to silence this warning
173 jailletc36: This has been done in r1711919
174 ylavic: Also, I don't think the changes on worker/event are needed,
175 prefork only requires the accept mutex in ONE_PROCESS mode.
177 *) mod_ssl: Fix missing TLS Upgrade/Connection headers on OPTIONS * requests
178 (Note that this is simply a necessary band-aid, and still won't allow h2c
179 to peacefully coexist with tls/n.n upgrades, because Upgrade phase needs
180 to come earlier, not as a handler, and the bogus connection-close behavior
181 must be removed before the Protocol API can handle TLS upgrade.)
183 trunk patch: http://svn.apache.org/r1717816
185 ylavic: how about adding !ap_request_has_body(r) to the test then?
186 wrowe responds: nonstarter, as discussed on list.
188 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
189 SSLCryptoDevice does not get unregistered because of non-zero refcount
190 during the mod_ssl unload happening on httpd startup.
191 trunk patch: http://svn.apache.org/r1720129
192 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
195 *) mod_cache_socache: Fix a possible cached entity body corruption when it
196 is received from an origin server in multiple batches and forwarded by
198 trunk patch: http://svn.apache.org/r1721899
199 2.4.x patch: trunk works, module CHANGES
202 *) mod_ssl: Constify + save a few bytes in conf pool when parsing SSLRequire
203 mod_nw_ssl: Save a few bytes in conf pool when processing 'NWSSLTrustedCerts'
204 trunk patch: http://svn.apache.org/r1718514
205 http://svn.apache.org/r1721313 (untested because I don't have this system)
206 2.4.x patch: trunk works
209 *) mod_ssl: Save some TLS record (application data) fragmentations by
210 including the last and subsequent suitable buckets when coalescing.
211 trunk patch: http://svn.apache.org/r1723122
212 http://svn.apache.org/r1723143
213 http://svn.apache.org/r1723284
214 2.4.x patch: trunk works, modulo CHANGES (from both r1723122,1723284)
215 For convenience (possibly):
216 http://people.apache.org/~ylavic/httpd-2.4.x-ssl_io_filter_coalesce.patch
219 *) mod_rewrite: Avoid looping on relative substitutions that
220 result in the same filename we started with.
222 trunk patch: http://svn.apache.org/r1724656
226 *) mod_cgid: drop severity of flush error message to match
228 trunk patch: http://svn.apache.org/r1724847
232 *) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,
233 "Error dispatching request", when the cause appears to be
234 the client closing the connection. PR58118
235 trunk patch: http://svn.apache.org/r1724857
236 2.4.x patch: trunk works
239 *) core: Add expr= support to SetHandler (someone wanted this in
240 a well-articulated serverfault post).
241 trunk patch: http://svn.apache.org/r1725149
242 http://svn.apache.org/r1725151
243 2.4.x patch: MMN/changes only: http://people.apache.org/~covener/patches/2.4.x-sethandler-expr.diff
246 PATCHES/ISSUES THAT ARE BEING WORKED
248 *) http: Don't remove the Content-Length of zero from a HEAD response if
249 it comes from an origin server, module or script. Allow the previous
250 behaviour (for legacy/buggy modules only, not origin) by also backporting
251 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
252 comes for free with the same commit).
253 trunk patch: http://svn.apache.org/r1554303
254 http://svn.apache.org/r1678215
255 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
257 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
258 ints added at the end of core_server_config, the proposed merge
259 does a minor bump only.
260 minfrin: Two new directives need to be documented.
262 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
263 fetching the request body, so to minimize the delay between it is supposed
264 to be alive and the first bytes sent: this is a best effort to prevent the
265 backend from closing because of idle or keepalive timeout in the meantime.
266 Also, handle a new "proxy-flushall" environment variable which allows to
267 flush any forwarded body data immediately. PR 56541+37920.
268 trunk patch: http://svn.apache.org/r1656259
269 http://svn.apache.org/r1656359 (CHANGES entry)
270 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
272 -0: jim: This seems to be a hit to normal performance, to handle an
273 error and/or non-normal condition. The pre-fetch is
274 expensive, and is always done, even before we know that
275 the backend is available to rec' it. I understand the
276 error described, but is the fix actually worth it (plus
277 it seems to allow for a DDoS vector).
278 ylavic: It seems to me that the problem is real since we reuse the
279 connection before prefetching 16K (either controlled by the
280 client, or by an input filter), we currently always prefetch
281 these bytes already. Regarding performance I don't see any
282 difference (more cycles) compared with the current code.
283 However I think I failed to rebuild the header_brigade when
284 the proxy loop is retried (ping), so I need to rework this.
285 Do you think we'd better remove the prefetch, or maybe just
286 make it nonblocking (by default)?
287 jim: Non-blocking seems the best way to handle...
289 PATCHES/ISSUES THAT ARE STALLED
291 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
292 backport keeps syslog logging as part of httpd core and only adds
293 API to allow other modules to be used for error logging.
294 trunk patch: http://svn.apache.org/r1525597
295 http://svn.apache.org/r1525664
296 http://svn.apache.org/r1525845
297 http://svn.apache.org/r1527003

304 http://svn.apache.org/r1626978
305 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
307 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
308 needs 2 args which is not valid in ErrorLog manual)
309 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
310 (sorry, haven't finished reviewing completely)
311 jim: What is the status of this??
313 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
314 and ProxyMatch section to distinguish between normal workers and workers
315 with regex substitutions in the name. Implement handling of such workers
316 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
317 matched and used for request. PR 43513.
318 trunk patch: http://svn.apache.org/r1609680
319 http://svn.apache.org/r1609688
320 http://svn.apache.org/r1641381
321 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
322 Also added missing r1609688 to the patchset.
323 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
325 -0: covener tried to review this one in Austin with Jeff. Does the added match function
326 really cover a very narrow set of parameters with the way it skips over backreferences?
327 Also, why a new API vs. just setting the field inline?
329 * mod_systemd: New module, for integration with systemd on Linux.

338 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
341 * mod_journald: Add new module mod_journald to log error logs into journald.
342 This patch needs changes done in mod_systemd patch (already

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

365 504 Gateway Timout as opposed to 502 Bad Gateway
366 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058

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

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

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