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 trunk patch: http://svn.apache.org/r1711479
132 2.4.x patch: trunk works
134 minfrin: Needs extra parens to suppress a warning:
135 prefork.c:1319:16: note: place parentheses around the assignment
136 to silence this warning
137 jailletc36: This has been done in r1711919
138 ylavic: Also, I don't think the changes on worker/event are needed,
139 only prefork requires the accept mutex in ONE_PROCESS mode.
141 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
142 SSLCryptoDevice does not get unregistered because of non-zero refcount
143 during the mod_ssl unload happening on httpd startup.
144 trunk patch: http://svn.apache.org/r1720129
145 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
147 ylavic: +1 with r1723295 (likewise for ecparams).
149 *) mod_cache_socache: Fix a possible cached entity body corruption when it

176 Trunk patch applies clean, modulo CHANGES
179 *) core: Track the useragent_host per-request when mod_remoteip or similar
180 modules track a per-request useragent_ip. Modules should be updated
181 to inquire for ap_get_useragent_host() in place of ap_get_remote_host().

195 Backport patch to r1729931 is noted in the commit log message
196 Requires r1729929 to be applied.
199 *) core: introducing new hook "pre_close_connection" to give protocols other
200 than http/1.1 a chance to send one last frame before close. Scoreboard
201 additions to allow update from master connections.
203 trunk patch: http://svn.apache.org/r1727071
204 http://svn.apache.org/r1727573
205 2.4.x patch: trunk works (modulo CHANGES)
206 covener: needs MMN bump, but sorting out previous MMN question first.
207 jim: Status, re: MMN bump ??
208 icing: I am embarrassingly bad at this. I propose to include the scoreboard
209 additions into this bump and propose all this together. So the new
210 proposal is (including an old apr_time_now() optimization from jim
211 for scorebaord.c). And that now includes all backports necessary to
212 update mod_http2 in 2.4.x:

219 http://svn.apache.org/r1729376
220 http://svn.apache.org/r1729960
221 2.4.x patch: trunk works (modulo CHANGES)
225 PATCHES/ISSUES THAT ARE BEING WORKED
227 *) http: Don't remove the Content-Length of zero from a HEAD response if
228 it comes from an origin server, module or script. Allow the previous
229 behaviour (for legacy/buggy modules only, not origin) by also backporting
230 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
231 comes for free with the same commit).
232 trunk patch: http://svn.apache.org/r1554303
233 http://svn.apache.org/r1678215
234 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
236 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
237 ints added at the end of core_server_config, the proposed merge
238 does a minor bump only.
239 minfrin: Two new directives need to be documented.
241 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
242 fetching the request body, so to minimize the delay between it is supposed
243 to be alive and the first bytes sent: this is a best effort to prevent the
244 backend from closing because of idle or keepalive timeout in the meantime.
245 Also, handle a new "proxy-flushall" environment variable which allows to
246 flush any forwarded body data immediately. PR 56541+37920.
247 trunk patch: http://svn.apache.org/r1656259
248 http://svn.apache.org/r1656359 (CHANGES entry)
249 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
251 -0: jim: This seems to be a hit to normal performance, to handle an
252 error and/or non-normal condition. The pre-fetch is
253 expensive, and is always done, even before we know that
254 the backend is available to rec' it. I understand the
255 error described, but is the fix actually worth it (plus
256 it seems to allow for a DDoS vector).
257 ylavic: It seems to me that the problem is real since we reuse the
258 connection before prefetching 16K (either controlled by the
259 client, or by an input filter), we currently always prefetch
260 these bytes already. Regarding performance I don't see any
261 difference (more cycles) compared with the current code.
262 However I think I failed to rebuild the header_brigade when
263 the proxy loop is retried (ping), so I need to rework this.
264 Do you think we'd better remove the prefetch, or maybe just
265 make it nonblocking (by default)?
266 jim: Non-blocking seems the best way to handle...
268 PATCHES/ISSUES THAT ARE STALLED
270 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
271 backport keeps syslog logging as part of httpd core and only adds
272 API to allow other modules to be used for error logging.
273 trunk patch: http://svn.apache.org/r1525597
274 http://svn.apache.org/r1525664
275 http://svn.apache.org/r1525845

282 http://svn.apache.org/r1544156
283 http://svn.apache.org/r1626978
284 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
286 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
287 needs 2 args which is not valid in ErrorLog manual)
288 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
289 (sorry, haven't finished reviewing completely)
290 jim: What is the status of this??
292 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
293 and ProxyMatch section to distinguish between normal workers and workers
294 with regex substitutions in the name. Implement handling of such workers
295 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
296 matched and used for request. PR 43513.
297 trunk patch: http://svn.apache.org/r1609680
298 http://svn.apache.org/r1609688
299 http://svn.apache.org/r1641381
300 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
301 Also added missing r1609688 to the patchset.
302 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
304 -0: covener tried to review this one in Austin with Jeff. Does the added match function
305 really cover a very narrow set of parameters with the way it skips over backreferences?
306 Also, why a new API vs. just setting the field inline?
308 * mod_systemd: New module, for integration with systemd on Linux.
309 trunk patch: http://svn.apache.org/r1393976

317 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
320 * mod_journald: Add new module mod_journald to log error logs into journald.
321 This patch needs changes done in mod_systemd patch (already

325 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
327 rjung, minfrin: Not understanding "This patch needs changes done in

330 jkaluza: No, that patch is not committed yet. It is in STALLED section.
331 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
333 * core: Add support for systemd socket activation.

340 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
343 * mod_proxy: Ensure network errors detected by the proxy are returned as
344 504 Gateway Timout as opposed to 502 Bad Gateway
345 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
346 2.4.x patch: trunk patch works modulo CHANGES
348 -1: rpluem: This change is still disputed. See

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

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

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