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
109 RELEASE SHOWSTOPPERS:
112 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
113 [ start all new proposals below, under PATCHES PROPOSED. ]
117 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
118 [ New proposals should be added at the end of the list ]
120 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
121 and Redirect. Limit Redirect expressions to directory (Location) context
122 and redirect statuses (implicit or explicit).
123 trunk patch: http://svn.apache.org/r1653941
124 http://svn.apache.org/r1653978
125 http://svn.apache.org/r1656225
126 http://svn.apache.org/r1686853
127 http://svn.apache.org/r1686856
128 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
131 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
132 its parameter when starting httpd as single process (httpd -X).
133 trunk patch: http://svn.apache.org/r1711479
134 2.4.x patch: trunk works
136 minfrin: Needs extra parens to suppress a warning:
137 prefork.c:1319:16: note: place parentheses around the assignment
138 to silence this warning
139 jailletc36: This has been done in r1711919
140 ylavic: Also, I don't think the changes on worker/event are needed,
141 prefork only requires the accept mutex in ONE_PROCESS mode.
143 *) mod_ssl: Fix missing TLS Upgrade/Connection headers on OPTIONS * requests
144 (Note that this is simply a necessary band-aid, and still won't allow h2c
145 to peacefully coexist with tls/n.n upgrades, because Upgrade phase needs
146 to come earlier, not as a handler, and the bogus connection-close behavior
147 must be removed before the Protocol API can handle TLS upgrade.)
149 trunk patch: http://svn.apache.org/r1717816
151 ylavic: how about adding !ap_request_has_body(r) to the test then?
152 wrowe responds: nonstarter, as discussed on list.
154 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
155 SSLCryptoDevice does not get unregistered because of non-zero refcount
156 during the mod_ssl unload happening on httpd startup.
157 trunk patch: http://svn.apache.org/r1720129
158 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
161 *) mod_cache_socache: Fix a possible cached entity body corruption when it
162 is received from an origin server in multiple batches and forwarded by
164 trunk patch: http://svn.apache.org/r1721899
165 2.4.x patch: trunk works, module CHANGES
168 *) mod_ssl: Constify + save a few bytes in conf pool when parsing SSLRequire
169 mod_nw_ssl: Save a few bytes in conf pool when processing 'NWSSLTrustedCerts'
170 trunk patch: http://svn.apache.org/r1718514
171 http://svn.apache.org/r1721313 (untested because I don't have this system)
172 2.4.x patch: trunk works
175 *) core: Save memory when calling 'ap_parse_htaccess'
176 trunk patch: http://svn.apache.org/r1719016
177 2.4.x patch: trunk works
180 *) Use 'apr_pstrmemdup' instead of 'apr_pstrndup' when applicable in order
181 to save a few cycles.
182 Fix some style issues.
183 trunk patch: http://svn.apache.org/r1719018
184 http://svn.apache.org/r1719189
185 http://svn.apache.org/r1719190
186 2.4.x patch: trunk works

193 http://svn.apache.org/r1719254
194 http://svn.apache.org/r1719255
195 http://svn.apache.org/r1720996 (change in ap_method_in_list not
196 tested, it is not actually used)
197 2.4.x patch: trunk works
200 *) mod_mod_authn_socache: Do not use the magic string "directory". Use the
201 corresponding global variable as in all other places of the module.
202 trunk patch: http://svn.apache.org/r1719257
203 2.4.x patch: trunk works
206 *) mod_ssl: Save some TLS record (application data) fragmentations by
207 including the last and subsequent suitable buckets when coalescing.
208 trunk patch: http://svn.apache.org/r1723122
209 http://svn.apache.org/r1723143
210 http://svn.apache.org/r1723284
211 2.4.x patch: trunk works, modulo CHANGES (from both r1723122,1723284)
212 For convenience (possibly):
213 http://people.apache.org/~ylavic/httpd-2.4.x-ssl_io_filter_coalesce.patch
216 *) mime.types: Add common extension "m4a" for MPEG 4 Audio.
217 As a reference see Wikipedia:
218 https://en.wikipedia.org/wiki/MPEG-4_Part_14#.MP4_versus_.M4A
220 trunk patch: http://svn.apache.org/r1723567
221 2.4.x patch: trunk works, modulo CHANGES
224 *) mod_rewrite: Avoid looping on relative substitutions that
225 result in the same filename we started with.
227 trunk patch: http://svn.apache.org/r1724656
231 *) mod_cgid: drop severity of flush error message to match
233 trunk patch: http://svn.apache.org/r1724847
237 *) mod_proxy_fcgi: Suppress HTTP error 503 and message 01075,
238 "Error dispatching request", when the cause appears to be
239 the client closing the connection. PR58118
240 trunk patch: http://svn.apache.org/r1724857
241 2.4.x patch: trunk works
244 PATCHES/ISSUES THAT ARE BEING WORKED
246 *) http: Don't remove the Content-Length of zero from a HEAD response if
247 it comes from an origin server, module or script. Allow the previous
248 behaviour (for legacy/buggy modules only, not origin) by also backporting
249 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
250 comes for free with the same commit).
251 trunk patch: http://svn.apache.org/r1554303
252 http://svn.apache.org/r1678215
253 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
255 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
256 ints added at the end of core_server_config, the proposed merge
257 does a minor bump only.
258 minfrin: Two new directives need to be documented.
260 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
261 fetching the request body, so to minimize the delay between it is supposed
262 to be alive and the first bytes sent: this is a best effort to prevent the
263 backend from closing because of idle or keepalive timeout in the meantime.
264 Also, handle a new "proxy-flushall" environment variable which allows to
265 flush any forwarded body data immediately. PR 56541+37920.
266 trunk patch: http://svn.apache.org/r1656259
267 http://svn.apache.org/r1656359 (CHANGES entry)
268 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
270 -0: jim: This seems to be a hit to normal performance, to handle an
271 error and/or non-normal condition. The pre-fetch is
272 expensive, and is always done, even before we know that
273 the backend is available to rec' it. I understand the
274 error described, but is the fix actually worth it (plus
275 it seems to allow for a DDoS vector).
276 ylavic: It seems to me that the problem is real since we reuse the
277 connection before prefetching 16K (either controlled by the
278 client, or by an input filter), we currently always prefetch
279 these bytes already. Regarding performance I don't see any
280 difference (more cycles) compared with the current code.
281 However I think I failed to rebuild the header_brigade when
282 the proxy loop is retried (ping), so I need to rework this.
283 Do you think we'd better remove the prefetch, or maybe just
284 make it nonblocking (by default)?
285 jim: Non-blocking seems the best way to handle...
287 PATCHES/ISSUES THAT ARE STALLED
289 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
290 backport keeps syslog logging as part of httpd core and only adds
291 API to allow other modules to be used for error logging.
292 trunk patch: http://svn.apache.org/r1525597
293 http://svn.apache.org/r1525664

302 http://svn.apache.org/r1626978
303 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
305 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
306 needs 2 args which is not valid in ErrorLog manual)
307 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
308 (sorry, haven't finished reviewing completely)
309 jim: What is the status of this??
311 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
312 and ProxyMatch section to distinguish between normal workers and workers
313 with regex substitutions in the name. Implement handling of such workers
314 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
315 matched and used for request. PR 43513.
316 trunk patch: http://svn.apache.org/r1609680
317 http://svn.apache.org/r1609688
318 http://svn.apache.org/r1641381
319 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
320 Also added missing r1609688 to the patchset.
321 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
323 -0: covener tried to review this one in Austin with Jeff. Does the added match function
324 really cover a very narrow set of parameters with the way it skips over backreferences?
325 Also, why a new API vs. just setting the field inline?
327 * mod_systemd: New module, for integration with systemd on Linux.
328 trunk patch: http://svn.apache.org/r1393976

336 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
339 * mod_journald: Add new module mod_journald to log error logs into journald.
340 This patch needs changes done in mod_systemd patch (already

346 rjung, minfrin: Not understanding "This patch needs changes done in
347 mod_systemd patch", am I right in understanding this patch is
349 jkaluza: No, that patch is not committed yet. It is in STALLED section.
350 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
352 * core: Add support for systemd socket activation.

359 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
362 * mod_proxy: Ensure network errors detected by the proxy are returned as
363 504 Gateway Timout as opposed to 502 Bad Gateway
364 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
365 2.4.x patch: trunk patch works modulo CHANGES
367 -1: rpluem: This change is still disputed. See

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

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

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