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 *) core: introducing new hook "pre_close_connection" to give protocols other
116 than http/1.1 a chance to send one last frame before close.
118 trunk patch: http://svn.apache.org/r1727071
119 http://svn.apache.org/r1727573
120 2.4.x patch: trunk works (modulo CHANGES)
121 +1: icing, covener, ylavic
122 covener: needs MMN bump, but sorting out previous MMN question first.
123 jim: Status, re: MMN bump ??
126 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
127 [ New proposals should be added at the end of the list ]
129 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
130 and Redirect. Limit Redirect expressions to directory (Location) context
131 and redirect statuses (implicit or explicit).
132 trunk patch: http://svn.apache.org/r1653941
133 http://svn.apache.org/r1653978
134 http://svn.apache.org/r1656225
135 http://svn.apache.org/r1686853
136 http://svn.apache.org/r1686856
137 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
140 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
141 its parameter when starting httpd as single process (httpd -X).
142 trunk patch: http://svn.apache.org/r1711479
143 2.4.x patch: trunk works
145 minfrin: Needs extra parens to suppress a warning:
146 prefork.c:1319:16: note: place parentheses around the assignment
147 to silence this warning
148 jailletc36: This has been done in r1711919
149 ylavic: Also, I don't think the changes on worker/event are needed,
150 only prefork requires the accept mutex in ONE_PROCESS mode.
152 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
153 SSLCryptoDevice does not get unregistered because of non-zero refcount
154 during the mod_ssl unload happening on httpd startup.
155 trunk patch: http://svn.apache.org/r1720129
156 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
158 ylavic: +1 with r1723295 (likewise for ecparams).
160 *) mod_cache_socache: Fix a possible cached entity body corruption when it
161 is received from an origin server in multiple batches and forwarded by
163 trunk patch: http://svn.apache.org/r1721899
164 2.4.x patch: trunk works, module CHANGES

177 Trunk version of patch:
178 Backport version for 2.4.x of patch:
181 *) mod_remoteip: Prevent an external proxy from presenting an internal proxy
183 Trunk version of patch:
184 http://svn.apache.org/r1588330
185 Trunk patch applies clean, modulo CHANGES
188 PATCHES/ISSUES THAT ARE BEING WORKED
190 *) http: Don't remove the Content-Length of zero from a HEAD response if
191 it comes from an origin server, module or script. Allow the previous
192 behaviour (for legacy/buggy modules only, not origin) by also backporting
193 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
194 comes for free with the same commit).
195 trunk patch: http://svn.apache.org/r1554303
196 http://svn.apache.org/r1678215
197 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
199 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
200 ints added at the end of core_server_config, the proposed merge
201 does a minor bump only.
202 minfrin: Two new directives need to be documented.
204 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
205 fetching the request body, so to minimize the delay between it is supposed
206 to be alive and the first bytes sent: this is a best effort to prevent the
207 backend from closing because of idle or keepalive timeout in the meantime.
208 Also, handle a new "proxy-flushall" environment variable which allows to
209 flush any forwarded body data immediately. PR 56541+37920.
210 trunk patch: http://svn.apache.org/r1656259
211 http://svn.apache.org/r1656359 (CHANGES entry)
212 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
214 -0: jim: This seems to be a hit to normal performance, to handle an
215 error and/or non-normal condition. The pre-fetch is
216 expensive, and is always done, even before we know that
217 the backend is available to rec' it. I understand the
218 error described, but is the fix actually worth it (plus
219 it seems to allow for a DDoS vector).
220 ylavic: It seems to me that the problem is real since we reuse the
221 connection before prefetching 16K (either controlled by the
222 client, or by an input filter), we currently always prefetch
223 these bytes already. Regarding performance I don't see any
224 difference (more cycles) compared with the current code.
225 However I think I failed to rebuild the header_brigade when
226 the proxy loop is retried (ping), so I need to rework this.
227 Do you think we'd better remove the prefetch, or maybe just
228 make it nonblocking (by default)?
229 jim: Non-blocking seems the best way to handle...
231 PATCHES/ISSUES THAT ARE STALLED
233 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
234 backport keeps syslog logging as part of httpd core and only adds
235 API to allow other modules to be used for error logging.
236 trunk patch: http://svn.apache.org/r1525597
237 http://svn.apache.org/r1525664
238 http://svn.apache.org/r1525845
239 http://svn.apache.org/r1527003

245 http://svn.apache.org/r1544156
246 http://svn.apache.org/r1626978
247 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
249 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
250 needs 2 args which is not valid in ErrorLog manual)
251 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
252 (sorry, haven't finished reviewing completely)
253 jim: What is the status of this??
255 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
256 and ProxyMatch section to distinguish between normal workers and workers
257 with regex substitutions in the name. Implement handling of such workers
258 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
259 matched and used for request. PR 43513.
260 trunk patch: http://svn.apache.org/r1609680
261 http://svn.apache.org/r1609688
262 http://svn.apache.org/r1641381
263 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
264 Also added missing r1609688 to the patchset.
265 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
267 -0: covener tried to review this one in Austin with Jeff. Does the added match function
268 really cover a very narrow set of parameters with the way it skips over backreferences?
269 Also, why a new API vs. just setting the field inline?
271 * mod_systemd: New module, for integration with systemd on Linux.
272 trunk patch: http://svn.apache.org/r1393976
273 http://svn.apache.org/r1393997

279 http://svn.apache.org/r1618588
280 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
283 * mod_journald: Add new module mod_journald to log error logs into journald.
284 This patch needs changes done in mod_systemd patch (already
286 trunk patch: http://svn.apache.org/r1610339
287 http://svn.apache.org/r1621806
288 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
290 rjung, minfrin: Not understanding "This patch needs changes done in
291 mod_systemd patch", am I right in understanding this patch is
293 jkaluza: No, that patch is not committed yet. It is in STALLED section.
294 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
296 * core: Add support for systemd socket activation.

303 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
306 * mod_proxy: Ensure network errors detected by the proxy are returned as
307 504 Gateway Timout as opposed to 502 Bad Gateway
308 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
309 2.4.x patch: trunk patch works modulo CHANGES
311 -1: rpluem: This change is still disputed. See
312 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
314 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
315 compiled by the build compiler instead of the host compiler.
316 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

329 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
332 This commit is essentially deciding that an httpd install on
333 Windows now has printenv/testcgi written in 2 more languages.
334 To the extent that the usefulness is that it shows how to make scripts
335 of these types executable by httpd, I believe that the documentation
336 is the proper place to solve that. To the extent that the usefullness
337 is to show how to implement a CGI in these particular languages, I believe
338 that the httpd distribution and documentation in general is not the
339 place for that. Historically these types of scripts have caused problems
340 for downstream vendorsas well as newbies (and sometimes the intersection
341 of those two groups) who don't understand that these are information leaks
342 once they are enabled, and the subtlety of the way they are disabled ("Apache
343 messed up the first line; let me fix that") contributes to that.
344 fuankg notes: I've just added a big warning to all CGI scripts which should now
345 make absolutely clear that these CGIs are for testing purpose only - so those
346 who enable those scripts with inserting the right shebang should be 100% aware
347 of any risks (this should cover your last point).
348 jim: trawick, does the above address your concerns?
349 trawick: to some extent (somebody reading the script gets an idea)
350 Why isn't the configuration requirement documented instead
351 of described indirectly in a sample?
352 Why are these new samples added to the install without three
353 votes? (I didn't veto it; put your name next to the two
354 existing ones and I'll be satisified that enough people
355 considered this addition as an appropriate solution for a
356 real httpd usability problem.)
357 wrowe: I'd agree with trawick, and suggest that these scripts can begin
358 their life somewhere in the manual/ tree. This really seems like
359 the place where /usr/share/httpd/examples/ would be useful, but
360 there isn't an ordinary directory for that. Since we want none
361 of the scripts to function 'out of the box', what about a new
362 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
