92 * Open bugs in the bug database.
94 * See also the STATUS file in the docs/ directory, which lists documentation-specific TODO items.
97 CURRENT RELEASE NOTES:
99 * Forward binary compatibility is expected of Apache 2.4.x releases, such
100 that no MMN major number changes will occur after 2.4.1. Such changes can
101 only be made in the trunk.
103 * All commits to branches/2.4.x must be reflected in SVN trunk,
104 as well, if they apply. Logical progression is commit to trunk
105 then merge into branches/2.4.x, as applicable.
107 * Current exceptions for RTC for this branch:
112 . non-Unix, single-platform code

172 http://svn.apache.org/r1752332
173 http://svn.apache.org/r1752333
176 *) mod_proxy_fcgi: read the whole FCGI response even when the content has

178 confusing error messages logged.
179 trunk patch: http://svn.apache.org/r1752347

208 2.4.x patch: trunk works (modulo CHANGES)
211 *) mod_cache: Use the actual URI path and query-string for identifying the

214 trunk patch: http://svn.apache.org/r1756553
215 http://svn.apache.org/r1756631

219 *) mod_proxy_{http,ajp,fcgi}: don't reuse backend connections with data
220 available before the request is sent. PR 57832.
221 This also backports deprecation of ap_proxy_ssl_connection_cleanup() and
222 newly introduced proxy_conn->tmp_bb's usage in proxy code (both almost
223 related and immediate/simple follow ups, merge simplified by doing so).
224 trunk patch: http://svn.apache.org/r1750392

231 http://home.apache.org/~ylavic/patches/httpd-2.4.x-r1750392.patch
234 *) mod_dav: fix typo (missing '/') in closing tag (follow up to r1756560
235 which backported r1746207 in 2.4.24). Plus r1748155 to fix compiling with
237 trunk patch: http://svn.apache.org/r1756611
238 http://svn.apache.org/r1748155
239 2.4.x patch: trunk works
243 PATCHES/ISSUES THAT ARE BEING WORKED
245 *) http: Don't remove the Content-Length of zero from a HEAD response if
246 it comes from an origin server, module or script. Allow the previous
247 behaviour (for legacy/buggy modules only, not origin) by also backporting
248 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
249 comes for free with the same commit).
250 trunk patch: http://svn.apache.org/r1554303
251 http://svn.apache.org/r1678215
252 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
254 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
255 ints added at the end of core_server_config, the proposed merge
256 does a minor bump only.
257 minfrin: Two new directives need to be documented.
259 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
260 fetching the request body, so to minimize the delay between it is supposed
261 to be alive and the first bytes sent: this is a best effort to prevent the
262 backend from closing because of idle or keepalive timeout in the meantime.
263 Also, handle a new "proxy-flushall" environment variable which allows to
264 flush any forwarded body data immediately. PR 56541+37920.
265 trunk patch: http://svn.apache.org/r1656259
266 http://svn.apache.org/r1656359 (CHANGES entry)
267 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
269 -0: jim: This seems to be a hit to normal performance, to handle an
270 error and/or non-normal condition. The pre-fetch is
271 expensive, and is always done, even before we know that
272 the backend is available to rec' it. I understand the
273 error described, but is the fix actually worth it (plus
274 it seems to allow for a DDoS vector).
275 ylavic: It seems to me that the problem is real since we reuse the
276 connection before prefetching 16K (either controlled by the
277 client, or by an input filter), we currently always prefetch
278 these bytes already. Regarding performance I don't see any
279 difference (more cycles) compared with the current code.
280 However I think I failed to rebuild the header_brigade when
281 the proxy loop is retried (ping), so I need to rework this.
282 Do you think we'd better remove the prefetch, or maybe just
283 make it nonblocking (by default)?
284 jim: Non-blocking seems the best way to handle...
286 * mod_dav: Allow other modules to become providers and add ACLs
287 to the DAV response. Requires a release of apr-util v1.6.
288 trunk patch: http://svn.apache.org/r1748322
289 2.4.x: trunk works modulo CHANGES/MMN
291 rpluem asks: Will this compile with apr-util < v1.6 and keep
292 mod_dav working (without the new features of the patch of course)?
293 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
294 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
295 minfrin: Yes, as you can see in the patch everything applies only
296 if APR_XML_X2T_PARSED is defined, and the patch was tested with
297 both apr-util v1.6 and apr-util v1.5.
299 PATCHES/ISSUES THAT ARE STALLED
301 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
302 backport keeps syslog logging as part of httpd core and only adds
303 API to allow other modules to be used for error logging.
304 trunk patch: http://svn.apache.org/r1525597
305 http://svn.apache.org/r1525664

315 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
317 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
318 needs 2 args which is not valid in ErrorLog manual)
319 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
320 (sorry, haven't finished reviewing completely)
321 jim: What is the status of this??
323 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
324 and ProxyMatch section to distinguish between normal workers and workers
325 with regex substitutions in the name. Implement handling of such workers
326 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
327 matched and used for request. PR 43513.
328 trunk patch: http://svn.apache.org/r1609680
329 http://svn.apache.org/r1609688
330 http://svn.apache.org/r1641381
331 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
332 Also added missing r1609688 to the patchset.
333 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
335 -0: covener tried to review this one in Austin with Jeff. Does the added match function
336 really cover a very narrow set of parameters with the way it skips over backreferences?
337 Also, why a new API vs. just setting the field inline?
339 * mod_systemd: New module, for integration with systemd on Linux.
340 trunk patch: http://svn.apache.org/r1393976

348 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
350 sf comments: The IdleShutdown logic seems broken. Consider a single
351 active connection that is stalled for 10 seconds. That
352 connection will be broken after GracefulShutdownTimeout.
353 A better logic would be to check if there is any open
354 connection that is not in keep-alive state.
356 * mod_journald: Add new module mod_journald to log error logs into journald.
357 This patch needs changes done in mod_systemd patch (already
359 trunk patch: http://svn.apache.org/r1610339

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

380 504 Gateway Timout as opposed to 502 Bad Gateway
381 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
382 2.4.x patch: trunk patch works modulo CHANGES
384 -1: rpluem: This change is still disputed. See

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

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

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

402 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
405 This commit is essentially deciding that an httpd install on
406 Windows now has printenv/testcgi written in 2 more languages.
407 To the extent that the usefulness is that it shows how to make scripts
408 of these types executable by httpd, I believe that the documentation
409 is the proper place to solve that. To the extent that the usefullness
410 is to show how to implement a CGI in these particular languages, I believe
411 that the httpd distribution and documentation in general is not the
412 place for that. Historically these types of scripts have caused problems
413 for downstream vendorsas well as newbies (and sometimes the intersection
414 of those two groups) who don't understand that these are information leaks
415 once they are enabled, and the subtlety of the way they are disabled ("Apache
416 messed up the first line; let me fix that") contributes to that.
417 fuankg notes: I've just added a big warning to all CGI scripts which should now
418 make absolutely clear that these CGIs are for testing purpose only - so those
419 who enable those scripts with inserting the right shebang should be 100% aware
420 of any risks (this should cover your last point).
421 jim: trawick, does the above address your concerns?
422 trawick: to some extent (somebody reading the script gets an idea)
423 Why isn't the configuration requirement documented instead
424 of described indirectly in a sample?
425 Why are these new samples added to the install without three
426 votes? (I didn't veto it; put your name next to the two
427 existing ones and I'll be satisified that enough people
428 considered this addition as an appropriate solution for a
429 real httpd usability problem.)
430 wrowe: I'd agree with trawick, and suggest that these scripts can begin
431 their life somewhere in the manual/ tree. This really seems like
432 the place where /usr/share/httpd/examples/ would be useful, but
