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: Fix missing TLS Upgrade/Connection headers on OPTIONS * requests
116 (Note that this is simply a necessary band-aid, and still won't allow h2c
117 to peacefully coexist with tls/n.n upgrades, because Upgrade phase needs
118 to come earlier, not as a handler, and the bogus connection-close behavior
119 must be removed before the Protocol API can handle TLS upgrade.)
121 trunk patch: http://svn.apache.org/r1717816
122 +1: wrowe, icing, ylavic
124 *) mod_ssl: handle APR_TIMEUP on empty input by keeping connection state valid
126 trunk patch: http://svn.apache.org/r1725940
127 +1: icing, jim, ylavic
129 *) core: Prevent a server crash in case of an invalid CONNECT request with
130 a custom error page for status code 400 that uses server side includes.
132 Trunk version of patch:
133 http://svn.apache.org/r1727544
134 Backport version for 2.4.x of patch:
135 Trunk version of patch works modulo CHANGES
136 +1: rpluem, covener, ylavic
138 *) core: Add expression support to SetHandler (someone wanted this in
139 a well-articulated serverfault post).
140 trunk patch: http://svn.apache.org/r1725149
141 http://svn.apache.org/r1725151
142 http://svn.apache.org/r1726233
143 http://svn.apache.org/r1729374
144 2.4.x patch: MMN/changes only: http://people.apache.org/~covener/patches/2.4.x-sethandler-expr-2.diff
145 + http://svn.apache.org/r1729374
146 +1: covener, jim, ylavic
148 *) core: introducing new hook "pre_close_connection" to give protocols other
149 than http/1.1 a chance to send one last frame before close.
151 trunk patch: http://svn.apache.org/r1727071
152 http://svn.apache.org/r1727573
153 2.4.x patch: trunk works (modulo CHANGES)
154 +1: icing, covener, ylavic
155 covener: needs MMN bump, but sorting out previous MMN question first.
158 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
159 [ New proposals should be added at the end of the list ]
161 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
162 and Redirect. Limit Redirect expressions to directory (Location) context
163 and redirect statuses (implicit or explicit).
164 trunk patch: http://svn.apache.org/r1653941
165 http://svn.apache.org/r1653978
166 http://svn.apache.org/r1656225
167 http://svn.apache.org/r1686853

169 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
172 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
173 its parameter when starting httpd as single process (httpd -X).
174 trunk patch: http://svn.apache.org/r1711479
175 2.4.x patch: trunk works
177 minfrin: Needs extra parens to suppress a warning:
178 prefork.c:1319:16: note: place parentheses around the assignment
179 to silence this warning
180 jailletc36: This has been done in r1711919
181 ylavic: Also, I don't think the changes on worker/event are needed,
182 only prefork requires the accept mutex in ONE_PROCESS mode.
184 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
185 SSLCryptoDevice does not get unregistered because of non-zero refcount
186 during the mod_ssl unload happening on httpd startup.
187 trunk patch: http://svn.apache.org/r1720129
188 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
190 ylavic: +1 with r1723295 (likewise for ecparams).
192 *) mod_cache_socache: Fix a possible cached entity body corruption when it
193 is received from an origin server in multiple batches and forwarded by
195 trunk patch: http://svn.apache.org/r1721899
196 2.4.x patch: trunk works, module CHANGES
199 *) mod_ssl: Add SSLOCSPProxyURL to add the possibility to do all queries
200 to OCSP responders through a HTTP proxy.

209 Trunk version of patch:
210 Backport version for 2.4.x of patch:
213 *) mod_remoteip: Prevent an external proxy from presenting an internal proxy
215 Trunk version of patch:
216 http://svn.apache.org/r1588330
217 Trunk patch applies clean, modulo CHANGES
220 PATCHES/ISSUES THAT ARE BEING WORKED
222 *) http: Don't remove the Content-Length of zero from a HEAD response if
223 it comes from an origin server, module or script. Allow the previous
224 behaviour (for legacy/buggy modules only, not origin) by also backporting
225 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
226 comes for free with the same commit).
227 trunk patch: http://svn.apache.org/r1554303
228 http://svn.apache.org/r1678215
229 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
231 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
232 ints added at the end of core_server_config, the proposed merge
233 does a minor bump only.
234 minfrin: Two new directives need to be documented.
236 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
237 fetching the request body, so to minimize the delay between it is supposed
238 to be alive and the first bytes sent: this is a best effort to prevent the
239 backend from closing because of idle or keepalive timeout in the meantime.
240 Also, handle a new "proxy-flushall" environment variable which allows to
241 flush any forwarded body data immediately. PR 56541+37920.
242 trunk patch: http://svn.apache.org/r1656259
243 http://svn.apache.org/r1656359 (CHANGES entry)
244 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
246 -0: jim: This seems to be a hit to normal performance, to handle an
247 error and/or non-normal condition. The pre-fetch is
248 expensive, and is always done, even before we know that
249 the backend is available to rec' it. I understand the
250 error described, but is the fix actually worth it (plus
251 it seems to allow for a DDoS vector).
252 ylavic: It seems to me that the problem is real since we reuse the
253 connection before prefetching 16K (either controlled by the
254 client, or by an input filter), we currently always prefetch
255 these bytes already. Regarding performance I don't see any
256 difference (more cycles) compared with the current code.
257 However I think I failed to rebuild the header_brigade when
258 the proxy loop is retried (ping), so I need to rework this.
259 Do you think we'd better remove the prefetch, or maybe just
260 make it nonblocking (by default)?
261 jim: Non-blocking seems the best way to handle...
263 PATCHES/ISSUES THAT ARE STALLED
265 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
266 backport keeps syslog logging as part of httpd core and only adds
267 API to allow other modules to be used for error logging.
268 trunk patch: http://svn.apache.org/r1525597
269 http://svn.apache.org/r1525664
270 http://svn.apache.org/r1525845
271 http://svn.apache.org/r1527003

277 http://svn.apache.org/r1544156
278 http://svn.apache.org/r1626978
279 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
281 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
282 needs 2 args which is not valid in ErrorLog manual)
283 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
284 (sorry, haven't finished reviewing completely)
285 jim: What is the status of this??
287 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
288 and ProxyMatch section to distinguish between normal workers and workers
289 with regex substitutions in the name. Implement handling of such workers
290 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
291 matched and used for request. PR 43513.
292 trunk patch: http://svn.apache.org/r1609680
293 http://svn.apache.org/r1609688
294 http://svn.apache.org/r1641381
295 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
296 Also added missing r1609688 to the patchset.
297 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
299 -0: covener tried to review this one in Austin with Jeff. Does the added match function
300 really cover a very narrow set of parameters with the way it skips over backreferences?
301 Also, why a new API vs. just setting the field inline?
303 * mod_systemd: New module, for integration with systemd on Linux.
304 trunk patch: http://svn.apache.org/r1393976

312 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
315 * mod_journald: Add new module mod_journald to log error logs into journald.
316 This patch needs changes done in mod_systemd patch (already
318 trunk patch: http://svn.apache.org/r1610339
319 http://svn.apache.org/r1621806
320 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
322 rjung, minfrin: Not understanding "This patch needs changes done in
323 mod_systemd patch", am I right in understanding this patch is
325 jkaluza: No, that patch is not committed yet. It is in STALLED section.
326 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
328 * core: Add support for systemd socket activation.

338 * mod_proxy: Ensure network errors detected by the proxy are returned as
339 504 Gateway Timout as opposed to 502 Bad Gateway
340 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
341 2.4.x patch: trunk patch works modulo CHANGES
343 -1: rpluem: This change is still disputed. See
344 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
346 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
347 compiled by the build compiler instead of the host compiler.
348 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

352 2.4 patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-cross_compile.diff
353 fuankg: on hold until we agree for a better and more simple solution ...
355 * Makefile.win: Added copying of .vbs / .wsf CGIs to Windows install target.
356 Moved fixing of shebang to separate target so that it is
357 no longer executed by default and all CGIs remain inactive.

361 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
364 This commit is essentially deciding that an httpd install on
365 Windows now has printenv/testcgi written in 2 more languages.
366 To the extent that the usefulness is that it shows how to make scripts
367 of these types executable by httpd, I believe that the documentation
368 is the proper place to solve that. To the extent that the usefullness
369 is to show how to implement a CGI in these particular languages, I believe
370 that the httpd distribution and documentation in general is not the
371 place for that. Historically these types of scripts have caused problems
372 for downstream vendorsas well as newbies (and sometimes the intersection
373 of those two groups) who don't understand that these are information leaks
374 once they are enabled, and the subtlety of the way they are disabled ("Apache
375 messed up the first line; let me fix that") contributes to that.
376 fuankg notes: I've just added a big warning to all CGI scripts which should now
377 make absolutely clear that these CGIs are for testing purpose only - so those
378 who enable those scripts with inserting the right shebang should be 100% aware
379 of any risks (this should cover your last point).
380 jim: trawick, does the above address your concerns?
381 trawick: to some extent (somebody reading the script gets an idea)
382 Why isn't the configuration requirement documented instead
383 of described indirectly in a sample?
384 Why are these new samples added to the install without three
385 votes? (I didn't veto it; put your name next to the two
386 existing ones and I'll be satisified that enough people
387 considered this addition as an appropriate solution for a
388 real httpd usability problem.)
389 wrowe: I'd agree with trawick, and suggest that these scripts can begin
390 their life somewhere in the manual/ tree. This really seems like
391 the place where /usr/share/httpd/examples/ would be useful, but
392 there isn't an ordinary directory for that. Since we want none
393 of the scripts to function 'out of the box', what about a new
394 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
