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).

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().

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

221 http://svn.apache.org/r1729960
222 2.4.x patch: trunk works (modulo CHANGES)
226 *) mod_watchdog: Error logging
227 trunk patch: http://svn.apache.org/r1722154
228 http://svn.apache.org/r1722701
229 2.4.x patch: trunk works
233 trunk patch: http://svn.apache.org/r1725485
234 2.4.x patch: trunk works
235 http://home.apache.org/~jim/patches/aplogno-2.4.patch
238 PATCHES/ISSUES THAT ARE BEING WORKED
240 *) http: Don't remove the Content-Length of zero from a HEAD response if
241 it comes from an origin server, module or script. Allow the previous
242 behaviour (for legacy/buggy modules only, not origin) by also backporting
243 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
244 comes for free with the same commit).
245 trunk patch: http://svn.apache.org/r1554303
246 http://svn.apache.org/r1678215
247 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
249 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
250 ints added at the end of core_server_config, the proposed merge
251 does a minor bump only.
252 minfrin: Two new directives need to be documented.
254 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
255 fetching the request body, so to minimize the delay between it is supposed
256 to be alive and the first bytes sent: this is a best effort to prevent the
257 backend from closing because of idle or keepalive timeout in the meantime.
258 Also, handle a new "proxy-flushall" environment variable which allows to
259 flush any forwarded body data immediately. PR 56541+37920.
260 trunk patch: http://svn.apache.org/r1656259
261 http://svn.apache.org/r1656359 (CHANGES entry)
262 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
264 -0: jim: This seems to be a hit to normal performance, to handle an
265 error and/or non-normal condition. The pre-fetch is
266 expensive, and is always done, even before we know that
267 the backend is available to rec' it. I understand the
268 error described, but is the fix actually worth it (plus
269 it seems to allow for a DDoS vector).
270 ylavic: It seems to me that the problem is real since we reuse the
271 connection before prefetching 16K (either controlled by the
272 client, or by an input filter), we currently always prefetch
273 these bytes already. Regarding performance I don't see any
274 difference (more cycles) compared with the current code.
275 However I think I failed to rebuild the header_brigade when
276 the proxy loop is retried (ping), so I need to rework this.
277 Do you think we'd better remove the prefetch, or maybe just
278 make it nonblocking (by default)?
279 jim: Non-blocking seems the best way to handle...
281 PATCHES/ISSUES THAT ARE STALLED
283 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
284 backport keeps syslog logging as part of httpd core and only adds
285 API to allow other modules to be used for error logging.
286 trunk patch: http://svn.apache.org/r1525597
287 http://svn.apache.org/r1525664
288 http://svn.apache.org/r1525845

295 http://svn.apache.org/r1544156
296 http://svn.apache.org/r1626978
297 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
299 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
300 needs 2 args which is not valid in ErrorLog manual)
301 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
302 (sorry, haven't finished reviewing completely)
303 jim: What is the status of this??
305 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
306 and ProxyMatch section to distinguish between normal workers and workers
307 with regex substitutions in the name. Implement handling of such workers
308 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
309 matched and used for request. PR 43513.
310 trunk patch: http://svn.apache.org/r1609680
311 http://svn.apache.org/r1609688
312 http://svn.apache.org/r1641381
313 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
314 Also added missing r1609688 to the patchset.
315 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
317 -0: covener tried to review this one in Austin with Jeff. Does the added match function
318 really cover a very narrow set of parameters with the way it skips over backreferences?
319 Also, why a new API vs. just setting the field inline?
321 * mod_systemd: New module, for integration with systemd on Linux.

333 * mod_journald: Add new module mod_journald to log error logs into journald.
334 This patch needs changes done in mod_systemd patch (already

343 jkaluza: No, that patch is not committed yet. It is in STALLED section.
344 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch

356 * mod_proxy: Ensure network errors detected by the proxy are returned as
357 504 Gateway Timout as opposed to 502 Bad Gateway
358 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
359 2.4.x patch: trunk patch works modulo CHANGES

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

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

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