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. ]
115 *) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
116 to OCSP responders through a HTTP proxy.
117 Trunk version of patch:
118 http://svn.apache.org/r1726881
119 http://svn.apache.org/r1727111
120 Backport version for 2.4.x of patch:
121 Trunk version of patch works modulo CHANGES
122 +1: rpluem, jim, ylavic
125 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
126 [ New proposals should be added at the end of the list ]
128 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
129 SSLCryptoDevice does not get unregistered because of non-zero refcount
130 during the mod_ssl unload happening on httpd startup.
131 trunk patch: http://svn.apache.org/r1720129
132 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
134 ylavic: +1 with r1723295 (likewise for ecparams).
135 rpluem says: Can we get an updated 2.4.x proposal that includes r1723295?
136 ylavic: working on it...
138 *) mod_proxy_hcheck: Dynamic reverse proxy backend health check module
139 Trunk version of patch: <various>
140 Backport version for 2.4.x of patch:
141 http://home.apache.org/~jim/patches/hcheck-2.4.patch
144 ylavic: Needs r1732957 for empty APLOGNO()s.
145 ylavic: Looks like the changes on struct proxy_worker_shared would break
146 startup with "BalancerPersist on" due to the strict checks on
147 the sizes of existing slotmems (slotmem_create/attach)?
149 *) core: Track the useragent_host per-request when mod_remoteip or similar
150 modules track a per-request useragent_ip. Modules should be updated
151 to inquire for ap_get_useragent_host() in place of ap_get_remote_host().
152 Trunk version of patch:
153 http://svn.apache.org/r1729929
154 Trunk patch to core.c/http_core.h applies, modulo CHANGES & ap_mmn.h
155 Note: httpd.h comment r.e. realiging bit fields must be omitted.
158 *) hostname: Test and log useragent_host per-request across various modules,
159 including the scoreboard, expression and rewrite engines, setenvif,
160 authz_host, access_compat, custom logging, ssl and REMOTE_HOST variables.

165 Trunk patch r1729930 applies, modulo CHANGES
166 Backport patch to r1729931 is noted in the commit log message
167 Requires r1729929 to be applied.
170 *) Use pre_connection hook in event.c to properly setup connection state
171 of slave connections (eliminates hacks in mod_http2).
173 http://svn.apache.org/r1727603
175 Trunk version of patch works modulo CHANGES
178 *) Save a few bytes in conf pool when parsing some directives
180 http://svn.apache.org/r1732252
181 http://svn.apache.org/r1732353
182 http://svn.apache.org/r1732369
184 Trunk version of patch works
185 +1: jailletc36, ylavic
187 *) proxy_util: Add missing APLOGNO()s from r1732266 (already backported
189 trunk patch: http://svn.apache.org/r1732954
190 2.4.x patch: trunk works (modulo docs/log-message-tags)
193 *) core: Add missing APLOGNO() from r1729495 (somehow r1725395 was
194 backported in r1729495 but without this "server/core.c" change)
195 trunk patch: http://svn.apache.org/viewvc/httpd/httpd/trunk/server/core.c?r1=1725395&r2=1725394&pathrev=1725395&view=patch
196 2.4.x patch: trunk above works
199 *) mod_proxy: Play/restore the TLS-SNI on new backend connections which
200 had to be issued because the remote closed the previous/reusable one
201 during idle (keep-alive) time.
202 trunk patch: http://svn.apache.org/r1729826
203 http://svn.apache.org/r1729847
204 http://svn.apache.org/r1732986
205 http://svn.apache.org/r1733056
206 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-mod_proxy-SNI_reuse-v2.patch
209 *) core: Fix a bug in <UnDefine ...> directive processing. When used, the
210 last <Define...>'ed variable was also withdrawn. PR 59019
212 http://svn.apache.org/r1732716
214 Trunk version of patch works (modulo CHNAGES)
218 PATCHES/ISSUES THAT ARE BEING WORKED
220 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
221 its parameter when starting httpd as single process (httpd -X).
222 trunk patch: http://svn.apache.org/r1711479
223 2.4.x patch: trunk works
225 minfrin: Needs extra parens to suppress a warning:
226 prefork.c:1319:16: note: place parentheses around the assignment
227 to silence this warning
228 jailletc36: This has been done in r1711919
229 ylavic: Also, I don't think the changes on worker/event are needed,
230 only prefork requires the accept mutex in ONE_PROCESS mode.
232 *) http: Don't remove the Content-Length of zero from a HEAD response if
233 it comes from an origin server, module or script. Allow the previous
234 behaviour (for legacy/buggy modules only, not origin) by also backporting
235 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
236 comes for free with the same commit).
237 trunk patch: http://svn.apache.org/r1554303
238 http://svn.apache.org/r1678215
239 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
241 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
242 ints added at the end of core_server_config, the proposed merge
243 does a minor bump only.
244 minfrin: Two new directives need to be documented.
246 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
247 fetching the request body, so to minimize the delay between it is supposed
248 to be alive and the first bytes sent: this is a best effort to prevent the
249 backend from closing because of idle or keepalive timeout in the meantime.
250 Also, handle a new "proxy-flushall" environment variable which allows to
251 flush any forwarded body data immediately. PR 56541+37920.
252 trunk patch: http://svn.apache.org/r1656259
253 http://svn.apache.org/r1656359 (CHANGES entry)
254 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
256 -0: jim: This seems to be a hit to normal performance, to handle an
257 error and/or non-normal condition. The pre-fetch is
258 expensive, and is always done, even before we know that
259 the backend is available to rec' it. I understand the
260 error described, but is the fix actually worth it (plus
261 it seems to allow for a DDoS vector).
262 ylavic: It seems to me that the problem is real since we reuse the
263 connection before prefetching 16K (either controlled by the
264 client, or by an input filter), we currently always prefetch
265 these bytes already. Regarding performance I don't see any
266 difference (more cycles) compared with the current code.
267 However I think I failed to rebuild the header_brigade when
268 the proxy loop is retried (ping), so I need to rework this.
269 Do you think we'd better remove the prefetch, or maybe just
270 make it nonblocking (by default)?
271 jim: Non-blocking seems the best way to handle...
273 PATCHES/ISSUES THAT ARE STALLED
275 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
276 backport keeps syslog logging as part of httpd core and only adds
277 API to allow other modules to be used for error logging.
278 trunk patch: http://svn.apache.org/r1525597
279 http://svn.apache.org/r1525664

288 http://svn.apache.org/r1626978
289 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
291 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
292 needs 2 args which is not valid in ErrorLog manual)
293 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
294 (sorry, haven't finished reviewing completely)
295 jim: What is the status of this??
297 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
298 and ProxyMatch section to distinguish between normal workers and workers
299 with regex substitutions in the name. Implement handling of such workers
300 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
301 matched and used for request. PR 43513.
302 trunk patch: http://svn.apache.org/r1609680
303 http://svn.apache.org/r1609688
304 http://svn.apache.org/r1641381
305 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
306 Also added missing r1609688 to the patchset.
307 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
309 -0: covener tried to review this one in Austin with Jeff. Does the added match function
310 really cover a very narrow set of parameters with the way it skips over backreferences?
311 Also, why a new API vs. just setting the field inline?
313 * mod_systemd: New module, for integration with systemd on Linux.
314 trunk patch: http://svn.apache.org/r1393976

322 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
324 sf comments: The IdleShutdown logic seems broken. Consider a single
325 active connection that is stalled for 10 seconds. That
326 connection will be broken after GracefulShutdownTimeout.
327 A better logic would be to check if there is any open
328 connection that is not in keep-alive state.
330 * mod_journald: Add new module mod_journald to log error logs into journald.
331 This patch needs changes done in mod_systemd patch (already
333 trunk patch: http://svn.apache.org/r1610339

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

353 * mod_proxy: Ensure network errors detected by the proxy are returned as
354 504 Gateway Timout as opposed to 502 Bad Gateway
355 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
356 2.4.x patch: trunk patch works modulo CHANGES
358 -1: rpluem: This change is still disputed. See
359 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
361 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
362 compiled by the build compiler instead of the host compiler.
363 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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