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 *) When more than one module calls APACHE_CHECK_OPENSSL, MOD_LDFLAGS and MOD_CFLAGS
116 remain unset for second or later caller. Fix this by caching the values for
117 MOD_LDFLAGS and MOD_CFLAGS created during the first run and set them in the
118 cached case. Change by rpluem
119 trunk patch: http://svn.apache.org/r1725325
120 2.4.x patch: trunk works
121 +1: icing, jim, ylavic
123 *) mod_ssl: Fix missing TLS Upgrade/Connection headers on OPTIONS * requests
124 (Note that this is simply a necessary band-aid, and still won't allow h2c
125 to peacefully coexist with tls/n.n upgrades, because Upgrade phase needs
126 to come earlier, not as a handler, and the bogus connection-close behavior
127 must be removed before the Protocol API can handle TLS upgrade.)
129 trunk patch: http://svn.apache.org/r1717816
130 +1: wrowe, icing, ylavic
132 *) mod_ssl: handle APR_TIMEUP on empty input by keeping connection state valid
134 trunk patch: http://svn.apache.org/r1725940
135 +1: icing, jim, ylavic
137 *) Add APLOGNO, first chunk (those that were detected by coccinelle).
138 There are some more but they are easier to backport once these here are applied.
139 trunk patch: http://svn.apache.org/r1725392 (modules)
140 http://svn.apache.org/r1725394 (server/mpm)
141 http://svn.apache.org/r1725395 (server others)

146 http://people.apache.org/~rjung/patches/aplogno-backport-r1725468.patch
147 +1: rjung, jim, ylavic
148 icing: needs http://svn.apache.org/r1725468
149 rjung: You are right, I added r1725468 and restarted the vote.
151 *) core: Prevent a server crash in case of an invalid CONNECT request with
152 a custom error page for status code 400 that uses server side includes.
154 Trunk version of patch:
155 http://svn.apache.org/r1727544
156 Backport version for 2.4.x of patch:
157 Trunk version of patch works modulo CHANGES
158 +1: rpluem, covener, ylavic
160 *) core: Add expression support to SetHandler (someone wanted this in
161 a well-articulated serverfault post).
162 trunk patch: http://svn.apache.org/r1725149
163 http://svn.apache.org/r1725151
164 http://svn.apache.org/r1726233
165 http://svn.apache.org/r1729374
166 2.4.x patch: MMN/changes only: http://people.apache.org/~covener/patches/2.4.x-sethandler-expr-2.diff
167 + http://svn.apache.org/r1729374
168 +1: covener, jim, ylavic
170 *) core: introducing new hook "pre_close_connection" to give protocols other
171 than http/1.1 a chance to send one last frame before close.
173 trunk patch: http://svn.apache.org/r1727071
174 http://svn.apache.org/r1727573
175 2.4.x patch: trunk works (modulo CHANGES)
176 +1: icing, covener, ylavic
177 covener: needs MMN bump, but sorting out previous MMN question first.
180 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
181 [ New proposals should be added at the end of the list ]
183 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
184 and Redirect. Limit Redirect expressions to directory (Location) context
185 and redirect statuses (implicit or explicit).
186 trunk patch: http://svn.apache.org/r1653941
187 http://svn.apache.org/r1653978
188 http://svn.apache.org/r1656225

191 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
194 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
195 its parameter when starting httpd as single process (httpd -X).
196 trunk patch: http://svn.apache.org/r1711479
197 2.4.x patch: trunk works
199 minfrin: Needs extra parens to suppress a warning:
200 prefork.c:1319:16: note: place parentheses around the assignment
201 to silence this warning
202 jailletc36: This has been done in r1711919
203 ylavic: Also, I don't think the changes on worker/event are needed,
204 only prefork requires the accept mutex in ONE_PROCESS mode.
206 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
207 SSLCryptoDevice does not get unregistered because of non-zero refcount
208 during the mod_ssl unload happening on httpd startup.
209 trunk patch: http://svn.apache.org/r1720129
210 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
212 ylavic: +1 with r1723295 (likewise for ecparams).
214 *) mod_cache_socache: Fix a possible cached entity body corruption when it
215 is received from an origin server in multiple batches and forwarded by
217 trunk patch: http://svn.apache.org/r1721899
218 2.4.x patch: trunk works, module CHANGES
221 *) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
222 to OCSP responders through a HTTP proxy.
223 Trunk version of patch:
224 http://svn.apache.org/r1726881
225 http://svn.apache.org/r1727111

230 *) mod_proxy_hcheck: Dynamic reverse proxy backend health check module
231 Trunk version of patch:
232 Backport version for 2.4.x of patch:
235 PATCHES/ISSUES THAT ARE BEING WORKED
237 *) http: Don't remove the Content-Length of zero from a HEAD response if
238 it comes from an origin server, module or script. Allow the previous
239 behaviour (for legacy/buggy modules only, not origin) by also backporting
240 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
241 comes for free with the same commit).
242 trunk patch: http://svn.apache.org/r1554303
243 http://svn.apache.org/r1678215
244 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
246 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
247 ints added at the end of core_server_config, the proposed merge
248 does a minor bump only.
249 minfrin: Two new directives need to be documented.
251 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
252 fetching the request body, so to minimize the delay between it is supposed
253 to be alive and the first bytes sent: this is a best effort to prevent the
254 backend from closing because of idle or keepalive timeout in the meantime.
255 Also, handle a new "proxy-flushall" environment variable which allows to
256 flush any forwarded body data immediately. PR 56541+37920.
257 trunk patch: http://svn.apache.org/r1656259
258 http://svn.apache.org/r1656359 (CHANGES entry)
259 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
261 -0: jim: This seems to be a hit to normal performance, to handle an
262 error and/or non-normal condition. The pre-fetch is
263 expensive, and is always done, even before we know that
264 the backend is available to rec' it. I understand the
265 error described, but is the fix actually worth it (plus
266 it seems to allow for a DDoS vector).
267 ylavic: It seems to me that the problem is real since we reuse the
268 connection before prefetching 16K (either controlled by the
269 client, or by an input filter), we currently always prefetch
270 these bytes already. Regarding performance I don't see any
271 difference (more cycles) compared with the current code.
272 However I think I failed to rebuild the header_brigade when
273 the proxy loop is retried (ping), so I need to rework this.
274 Do you think we'd better remove the prefetch, or maybe just
275 make it nonblocking (by default)?
276 jim: Non-blocking seems the best way to handle...
278 PATCHES/ISSUES THAT ARE STALLED
280 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
281 backport keeps syslog logging as part of httpd core and only adds
282 API to allow other modules to be used for error logging.
283 trunk patch: http://svn.apache.org/r1525597
284 http://svn.apache.org/r1525664
285 http://svn.apache.org/r1525845
286 http://svn.apache.org/r1527003

292 http://svn.apache.org/r1544156
293 http://svn.apache.org/r1626978
294 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
296 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
297 needs 2 args which is not valid in ErrorLog manual)
298 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
299 (sorry, haven't finished reviewing completely)
300 jim: What is the status of this??
302 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
303 and ProxyMatch section to distinguish between normal workers and workers
304 with regex substitutions in the name. Implement handling of such workers
305 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
306 matched and used for request. PR 43513.
307 trunk patch: http://svn.apache.org/r1609680
308 http://svn.apache.org/r1609688
309 http://svn.apache.org/r1641381
310 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
311 Also added missing r1609688 to the patchset.
312 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
314 -0: covener tried to review this one in Austin with Jeff. Does the added match function
315 really cover a very narrow set of parameters with the way it skips over backreferences?
316 Also, why a new API vs. just setting the field inline?
318 * mod_systemd: New module, for integration with systemd on Linux.
319 trunk patch: http://svn.apache.org/r1393976

327 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
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

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.

350 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
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

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
