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

117 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
118 [ New proposals should be added at the end of the list ]
120 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
121 SSLCryptoDevice does not get unregistered because of non-zero refcount
122 during the mod_ssl unload happening on httpd startup.
123 trunk patch: http://svn.apache.org/r1720129
124 http://svn.apache.org/r1723295

129 rpluem says: Can we get an updated 2.4.x proposal that includes r1723295?
130 ylavic: done + CHANGES (votes reset)
132 *) mod_proxy_hcheck: Dynamic reverse proxy backend health check module
133 Trunk version of patch: <various>
134 Backport version for 2.4.x of patch:
135 http://home.apache.org/~jim/patches/hcheck-2.4.patch
138 ylavic: Needs r1732957 for empty APLOGNO()s.
139 ylavic: Looks like the changes on struct proxy_worker_shared would break
140 startup with "BalancerPersist on" due to the strict checks on
141 the sizes of existing slotmems (slotmem_create/attach)?
143 *) core: Track the useragent_host per-request when mod_remoteip or similar
144 modules track a per-request useragent_ip. Modules should be updated
145 to inquire for ap_get_useragent_host() in place of ap_get_remote_host().
146 Trunk version of patch:
147 http://svn.apache.org/r1729929
148 Trunk patch to core.c/http_core.h applies, modulo CHANGES & ap_mmn.h
149 Note: httpd.h comment r.e. realiging bit fields must be omitted.
152 *) hostname: Test and log useragent_host per-request across various modules,
153 including the scoreboard, expression and rewrite engines, setenvif,
154 authz_host, access_compat, custom logging, ssl and REMOTE_HOST variables.

183 trunk patch: http://svn.apache.org/r1732954
184 2.4.x patch: trunk works (modulo docs/log-message-tags)
187 *) core: Add missing APLOGNO() from r1729495 (somehow r1725395 was
188 backported in r1729495 but without this "server/core.c" change)
189 trunk patch: http://svn.apache.org/viewvc/httpd/httpd/trunk/server/core.c?r1=1725395&r2=1725394&pathrev=1725395&view=patch
190 2.4.x patch: trunk above works
193 *) mod_proxy: Play/restore the TLS-SNI on new backend connections which
194 had to be issued because the remote closed the previous/reusable one
195 during idle (keep-alive) time.

206 http://svn.apache.org/r1732716
208 Trunk version of patch works (modulo CHNAGES)
209 +1: jailletc36, ylavic
211 * prefork: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
212 its parameter when starting httpd as single process (httpd -X).
213 trunk patch: http://svn.apache.org/r1711479
214 http://svn.apache.org/r1733064
215 http://svn.apache.org/r1733068
216 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-prefork-ONE_PROCESS_POD.patch
219 *) mod_ssl: When SSLVerify is disabled (NONE), don't force a renegotiation if
220 the SSLVerifyDepth applied with the default/handshaken vhost differs from
221 the one applicable with the finally selected vhost.
222 trunk patch: http://svn.apache.org/r1684171
223 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-SSLVerify_NONE_no_reneg_Depth.patch
227 PATCHES/ISSUES THAT ARE BEING WORKED
229 *) http: Don't remove the Content-Length of zero from a HEAD response if
230 it comes from an origin server, module or script. Allow the previous
231 behaviour (for legacy/buggy modules only, not origin) by also backporting
232 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
233 comes for free with the same commit).
234 trunk patch: http://svn.apache.org/r1554303
235 http://svn.apache.org/r1678215
236 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
238 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
239 ints added at the end of core_server_config, the proposed merge
240 does a minor bump only.
241 minfrin: Two new directives need to be documented.
243 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
244 fetching the request body, so to minimize the delay between it is supposed
245 to be alive and the first bytes sent: this is a best effort to prevent the
246 backend from closing because of idle or keepalive timeout in the meantime.
247 Also, handle a new "proxy-flushall" environment variable which allows to
248 flush any forwarded body data immediately. PR 56541+37920.
249 trunk patch: http://svn.apache.org/r1656259
250 http://svn.apache.org/r1656359 (CHANGES entry)
251 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
253 -0: jim: This seems to be a hit to normal performance, to handle an
254 error and/or non-normal condition. The pre-fetch is
255 expensive, and is always done, even before we know that
256 the backend is available to rec' it. I understand the
257 error described, but is the fix actually worth it (plus
258 it seems to allow for a DDoS vector).
259 ylavic: It seems to me that the problem is real since we reuse the
260 connection before prefetching 16K (either controlled by the
261 client, or by an input filter), we currently always prefetch
262 these bytes already. Regarding performance I don't see any
263 difference (more cycles) compared with the current code.
264 However I think I failed to rebuild the header_brigade when
265 the proxy loop is retried (ping), so I need to rework this.
266 Do you think we'd better remove the prefetch, or maybe just
267 make it nonblocking (by default)?
268 jim: Non-blocking seems the best way to handle...
270 PATCHES/ISSUES THAT ARE STALLED
272 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
273 backport keeps syslog logging as part of httpd core and only adds
274 API to allow other modules to be used for error logging.
275 trunk patch: http://svn.apache.org/r1525597
276 http://svn.apache.org/r1525664

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

319 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
321 sf comments: The IdleShutdown logic seems broken. Consider a single
322 active connection that is stalled for 10 seconds. That
323 connection will be broken after GracefulShutdownTimeout.
324 A better logic would be to check if there is any open
325 connection that is not in keep-alive state.
327 * mod_journald: Add new module mod_journald to log error logs into journald.
328 This patch needs changes done in mod_systemd patch (already

332 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
334 rjung, minfrin: Not understanding "This patch needs changes done in
335 mod_systemd patch", am I right in understanding this patch is
337 jkaluza: No, that patch is not committed yet. It is in STALLED section.
338 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
340 * core: Add support for systemd socket activation.

351 504 Gateway Timout as opposed to 502 Bad Gateway
352 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
353 2.4.x patch: trunk patch works modulo CHANGES
355 -1: rpluem: This change is still disputed. See
356 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
358 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
359 compiled by the build compiler instead of the host compiler.
360 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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