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

112 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
113 [ start all new proposals below, under PATCHES PROPOSED. ]
115 *) mod_log_config: PR58769: backport GlobalLog directive to 2.4.x
116 trunk patch: http://svn.apache.org/r1599535
117 http://svn.apache.org/r1721685
118 2.4.x patch: trunk works
119 +1 covener, jim, ylavic
120 ylavic: note: the CHANGES entry may be modified to remove Ed's email
121 address (leaving the full name only) since he is now a committer.
124 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
125 [ New proposals should be added at the end of the list ]
127 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
128 and Redirect. Limit Redirect expressions to directory (Location) context
129 and redirect statuses (implicit or explicit).
130 trunk patch: http://svn.apache.org/r1653941

134 http://svn.apache.org/r1686856
135 2.4.x patch: https://people.apache.org/~minfrin/httpd-mod_alias-expr2.patch
138 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
139 its parameter when starting httpd as single process (httpd -X).
140 trunk patch: http://svn.apache.org/r1711479
141 2.4.x patch: trunk works
143 minfrin: Needs extra parens to suppress a warning:
144 prefork.c:1319:16: note: place parentheses around the assignment
145 to silence this warning
146 jailletc36: This has been done in r1711919
147 ylavic: Also, I don't think the changes on worker/event are needed,
148 prefork only requires the accept mutex in ONE_PROCESS mode.
150 *) mod_ssl: Fix missing TLS Upgrade/Connection headers on OPTIONS * requests
151 (Note that this is simply a necessary band-aid, and still won't allow h2c
152 to peacefully coexist with tls/n.n upgrades, because Upgrade phase needs
153 to come earlier, not as a handler, and the bogus connection-close behavior
154 must be removed before the Protocol API can handle TLS upgrade.)
156 trunk patch: http://svn.apache.org/r1717816
158 ylavic: how about adding !ap_request_has_body(r) to the test then?
159 wrowe responds: nonstarter, as discussed on list.
161 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
162 SSLCryptoDevice does not get unregistered because of non-zero refcount
163 during the mod_ssl unload happening on httpd startup.
164 trunk patch: http://svn.apache.org/r1720129
165 2.4.x patch: http://jkaluza.fedorapeople.org/httpd-2.4.x-dhparams-free.patch
168 *) mod_cache_socache: Fix a possible cached entity body corruption when it
169 is received from an origin server in multiple batches and forwarded by
171 trunk patch: http://svn.apache.org/r1721899
172 2.4.x patch: trunk works, module CHANGES
176 PATCHES/ISSUES THAT ARE BEING WORKED
178 *) http: Don't remove the Content-Length of zero from a HEAD response if
179 it comes from an origin server, module or script. Allow the previous
180 behaviour (for legacy/buggy modules only, not origin) by also backporting
181 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
182 comes for free with the same commit).
183 trunk patch: http://svn.apache.org/r1554303
184 http://svn.apache.org/r1678215
185 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
187 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
188 ints added at the end of core_server_config, the proposed merge
189 does a minor bump only.
190 minfrin: Two new directives need to be documented.
192 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
193 fetching the request body, so to minimize the delay between it is supposed
194 to be alive and the first bytes sent: this is a best effort to prevent the
195 backend from closing because of idle or keepalive timeout in the meantime.
196 Also, handle a new "proxy-flushall" environment variable which allows to
197 flush any forwarded body data immediately. PR 56541+37920.
198 trunk patch: http://svn.apache.org/r1656259
199 http://svn.apache.org/r1656359 (CHANGES entry)
200 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
202 -0: jim: This seems to be a hit to normal performance, to handle an
203 error and/or non-normal condition. The pre-fetch is
204 expensive, and is always done, even before we know that
205 the backend is available to rec' it. I understand the
206 error described, but is the fix actually worth it (plus
207 it seems to allow for a DDoS vector).
208 ylavic: It seems to me that the problem is real since we reuse the
209 connection before prefetching 16K (either controlled by the
210 client, or by an input filter), we currently always prefetch
211 these bytes already. Regarding performance I don't see any
212 difference (more cycles) compared with the current code.
213 However I think I failed to rebuild the header_brigade when
214 the proxy loop is retried (ping), so I need to rework this.
215 Do you think we'd better remove the prefetch, or maybe just
216 make it nonblocking (by default)?
217 jim: Non-blocking seems the best way to handle...
219 PATCHES/ISSUES THAT ARE STALLED
221 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
222 backport keeps syslog logging as part of httpd core and only adds
223 API to allow other modules to be used for error logging.
224 trunk patch: http://svn.apache.org/r1525597
225 http://svn.apache.org/r1525664
226 http://svn.apache.org/r1525845

234 http://svn.apache.org/r1626978
235 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
237 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
238 needs 2 args which is not valid in ErrorLog manual)
239 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
240 (sorry, haven't finished reviewing completely)
241 jim: What is the status of this??
243 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
244 and ProxyMatch section to distinguish between normal workers and workers
245 with regex substitutions in the name. Implement handling of such workers
246 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
247 matched and used for request. PR 43513.
248 trunk patch: http://svn.apache.org/r1609680
249 http://svn.apache.org/r1609688
250 http://svn.apache.org/r1641381
251 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
252 Also added missing r1609688 to the patchset.
253 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
255 -0: covener tried to review this one in Austin with Jeff. Does the added match function
256 really cover a very narrow set of parameters with the way it skips over backreferences?
257 Also, why a new API vs. just setting the field inline?
259 * mod_systemd: New module, for integration with systemd on Linux.
260 trunk patch: http://svn.apache.org/r1393976
261 http://svn.apache.org/r1393997

268 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
271 * mod_journald: Add new module mod_journald to log error logs into journald.
272 This patch needs changes done in mod_systemd patch (already
274 trunk patch: http://svn.apache.org/r1610339
275 http://svn.apache.org/r1621806
276 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
278 rjung, minfrin: Not understanding "This patch needs changes done in
279 mod_systemd patch", am I right in understanding this patch is
281 jkaluza: No, that patch is not committed yet. It is in STALLED section.
282 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
284 * core: Add support for systemd socket activation.

291 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
294 * mod_proxy: Ensure network errors detected by the proxy are returned as
295 504 Gateway Timout as opposed to 502 Bad Gateway
296 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
297 2.4.x patch: trunk patch works modulo CHANGES
299 -1: rpluem: This change is still disputed. See

302 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
303 compiled by the build compiler instead of the host compiler.
304 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

309 fuankg: on hold until we agree for a better and more simple solution ...

312 Moved fixing of shebang to separate target so that it is
313 no longer executed by default and all CGIs remain inactive.

317 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
320 This commit is essentially deciding that an httpd install on
321 Windows now has printenv/testcgi written in 2 more languages.
322 To the extent that the usefulness is that it shows how to make scripts
323 of these types executable by httpd, I believe that the documentation
324 is the proper place to solve that. To the extent that the usefullness
325 is to show how to implement a CGI in these particular languages, I believe
326 that the httpd distribution and documentation in general is not the
327 place for that. Historically these types of scripts have caused problems
328 for downstream vendorsas well as newbies (and sometimes the intersection
329 of those two groups) who don't understand that these are information leaks
330 once they are enabled, and the subtlety of the way they are disabled ("Apache
331 messed up the first line; let me fix that") contributes to that.
332 fuankg notes: I've just added a big warning to all CGI scripts which should now
333 make absolutely clear that these CGIs are for testing purpose only - so those
334 who enable those scripts with inserting the right shebang should be 100% aware
335 of any risks (this should cover your last point).
336 jim: trawick, does the above address your concerns?
337 trawick: to some extent (somebody reading the script gets an idea)
338 Why isn't the configuration requirement documented instead
339 of described indirectly in a sample?
340 Why are these new samples added to the install without three
341 votes? (I didn't veto it; put your name next to the two
342 existing ones and I'll be satisified that enough people
343 considered this addition as an appropriate solution for a
344 real httpd usability problem.)
345 wrowe: I'd agree with trawick, and suggest that these scripts can begin
346 their life somewhere in the manual/ tree. This really seems like
347 the place where /usr/share/httpd/examples/ would be useful, but
348 there isn't an ordinary directory for that. Since we want none
349 of the scripts to function 'out of the box', what about a new
350 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
