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

137 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
138 [ New proposals should be added at the end of the list ]
140 *) mod_ssl: Free dhparams when getting DH params. This fixes issue when
141 SSLCryptoDevice does not get unregistered because of non-zero refcount
142 during the mod_ssl unload happening on httpd startup.
143 trunk patch: http://svn.apache.org/r1720129
144 http://svn.apache.org/r1723295

147 2.4.x patch: http://home.apache.org/~ylavic/patches/httpd-2.4.x-dh_leaks.patch
149 rpluem says: Can we get an updated 2.4.x proposal that includes r1723295?
150 ylavic: done + CHANGES (votes reset)
152 *) mod_proxy_hcheck: Dynamic reverse proxy backend health check module
153 Trunk version of patch: <various>
154 Backport version for 2.4.x of patch:
155 http://home.apache.org/~jim/patches/hcheck-2.4.patch
158 ylavic: Needs r1732957 for empty APLOGNO()s.
159 ylavic: Looks like the changes on struct proxy_worker_shared would break
160 startup with "BalancerPersist on" due to the strict checks on
161 the sizes of existing slotmems (slotmem_create/attach)?
163 *) Use pre_connection hook in event.c to properly setup connection state
164 of slave connections (eliminates hacks in mod_http2).
166 http://svn.apache.org/r1727603
168 Trunk version of patch works modulo CHANGES
171 *) proxy_util: Add missing APLOGNO()s from r1732266 (already backported
173 trunk patch: http://svn.apache.org/r1732954
174 2.4.x patch: trunk works (modulo docs/log-message-tags)
177 *) core: Add missing APLOGNO() from r1729495 (somehow r1725395 was
178 backported in r1729495 but without this "server/core.c" change)
179 trunk patch: http://svn.apache.org/viewvc/httpd/httpd/trunk/server/core.c?r1=1725395&r2=1725394&pathrev=1725395&view=patch
180 2.4.x patch: trunk above works
183 *) mod_proxy: Play/restore the TLS-SNI on new backend connections which
184 had to be issued because the remote closed the previous/reusable one
185 during idle (keep-alive) time.
186 trunk patch: http://svn.apache.org/r1729826
187 http://svn.apache.org/r1729847

190 2.4.x patch: http://home.apache.org/~ylavic/patches/httpd-2.4.x-mod_proxy-SNI_reuse-v2.patch
193 * prefork: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
194 its parameter when starting httpd as single process (httpd -X).
195 trunk patch: http://svn.apache.org/r1711479
196 http://svn.apache.org/r1733064

201 *) mod_ssl: When SSLVerify is disabled (NONE), don't force a renegotiation if
202 the SSLVerifyDepth applied with the default/handshaken vhost differs from
203 the one applicable with the finally selected vhost.
204 trunk patch: http://svn.apache.org/r1684171
205 2.4.x patch: http://home.apache.org/~ylavic/patches/httpd-2.4.x-SSLVerify_NONE_no_reneg_Depth.patch

215 2.4.x patch: http://home.apache.org/~ylavic/patches/httpd-2.4.x-exit_with_error_on_mpm_failure.patch
219 PATCHES/ISSUES THAT ARE BEING WORKED
221 *) http: Don't remove the Content-Length of zero from a HEAD response if
222 it comes from an origin server, module or script. Allow the previous
223 behaviour (for legacy/buggy modules only, not origin) by also backporting
224 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
225 comes for free with the same commit).
226 trunk patch: http://svn.apache.org/r1554303
227 http://svn.apache.org/r1678215
228 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
230 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
231 ints added at the end of core_server_config, the proposed merge
232 does a minor bump only.
233 minfrin: Two new directives need to be documented.
235 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
236 fetching the request body, so to minimize the delay between it is supposed
237 to be alive and the first bytes sent: this is a best effort to prevent the
238 backend from closing because of idle or keepalive timeout in the meantime.
239 Also, handle a new "proxy-flushall" environment variable which allows to
240 flush any forwarded body data immediately. PR 56541+37920.
241 trunk patch: http://svn.apache.org/r1656259
242 http://svn.apache.org/r1656359 (CHANGES entry)
243 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
245 -0: jim: This seems to be a hit to normal performance, to handle an
246 error and/or non-normal condition. The pre-fetch is
247 expensive, and is always done, even before we know that
248 the backend is available to rec' it. I understand the
249 error described, but is the fix actually worth it (plus
250 it seems to allow for a DDoS vector).
251 ylavic: It seems to me that the problem is real since we reuse the
252 connection before prefetching 16K (either controlled by the
253 client, or by an input filter), we currently always prefetch
254 these bytes already. Regarding performance I don't see any
255 difference (more cycles) compared with the current code.
256 However I think I failed to rebuild the header_brigade when
257 the proxy loop is retried (ping), so I need to rework this.
258 Do you think we'd better remove the prefetch, or maybe just
259 make it nonblocking (by default)?
260 jim: Non-blocking seems the best way to handle...
262 PATCHES/ISSUES THAT ARE STALLED
264 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
265 backport keeps syslog logging as part of httpd core and only adds
266 API to allow other modules to be used for error logging.
267 trunk patch: http://svn.apache.org/r1525597
268 http://svn.apache.org/r1525664
269 http://svn.apache.org/r1525845

276 http://svn.apache.org/r1544156
277 http://svn.apache.org/r1626978
278 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
280 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
281 needs 2 args which is not valid in ErrorLog manual)
282 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
283 (sorry, haven't finished reviewing completely)
284 jim: What is the status of this??
286 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
287 and ProxyMatch section to distinguish between normal workers and workers
288 with regex substitutions in the name. Implement handling of such workers
289 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
290 matched and used for request. PR 43513.
291 trunk patch: http://svn.apache.org/r1609680
292 http://svn.apache.org/r1609688
293 http://svn.apache.org/r1641381
294 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
295 Also added missing r1609688 to the patchset.
296 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
298 -0: covener tried to review this one in Austin with Jeff. Does the added match function
299 really cover a very narrow set of parameters with the way it skips over backreferences?
300 Also, why a new API vs. just setting the field inline?
302 * mod_systemd: New module, for integration with systemd on Linux.
303 trunk patch: http://svn.apache.org/r1393976

311 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
313 sf comments: The IdleShutdown logic seems broken. Consider a single
314 active connection that is stalled for 10 seconds. That
315 connection will be broken after GracefulShutdownTimeout.
316 A better logic would be to check if there is any open
317 connection that is not in keep-alive state.
319 * mod_journald: Add new module mod_journald to log error logs into journald.
320 This patch needs changes done in mod_systemd patch (already
322 trunk patch: http://svn.apache.org/r1610339

324 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
326 rjung, minfrin: Not understanding "This patch needs changes done in
327 mod_systemd patch", am I right in understanding this patch is
329 jkaluza: No, that patch is not committed yet. It is in STALLED section.
330 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
332 * core: Add support for systemd socket activation.

343 504 Gateway Timout as opposed to 502 Bad Gateway
344 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
345 2.4.x patch: trunk patch works modulo CHANGES
347 -1: rpluem: This change is still disputed. See
348 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
350 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
351 compiled by the build compiler instead of the host compiler.
352 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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