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

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

302 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
304 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
305 needs 2 args which is not valid in ErrorLog manual)
306 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
307 (sorry, haven't finished reviewing completely)
308 jim: What is the status of this??
310 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
311 and ProxyMatch section to distinguish between normal workers and workers
312 with regex substitutions in the name. Implement handling of such workers
313 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
314 matched and used for request. PR 43513.
315 trunk patch: http://svn.apache.org/r1609680
316 http://svn.apache.org/r1609688
317 http://svn.apache.org/r1641381
318 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
319 Also added missing r1609688 to the patchset.
320 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
322 -0: covener tried to review this one in Austin with Jeff. Does the added match function
323 really cover a very narrow set of parameters with the way it skips over backreferences?
324 Also, why a new API vs. just setting the field inline?
326 * mod_systemd: New module, for integration with systemd on Linux.

335 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
337 sf comments: The IdleShutdown logic seems broken. Consider a single
338 active connection that is stalled for 10 seconds. That
339 connection will be broken after GracefulShutdownTimeout.
340 A better logic would be to check if there is any open
341 connection that is not in keep-alive state.
343 * mod_journald: Add new module mod_journald to log error logs into journald.
344 This patch needs changes done in mod_systemd patch (already

350 rjung, minfrin: Not understanding "This patch needs changes done in
351 mod_systemd patch", am I right in understanding this patch is
353 jkaluza: No, that patch is not committed yet. It is in STALLED section.
354 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch

367 504 Gateway Timout as opposed to 502 Bad Gateway
368 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
369 2.4.x patch: trunk patch works modulo CHANGES
371 -1: rpluem: This change is still disputed. See

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

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

389 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
392 This commit is essentially deciding that an httpd install on
393 Windows now has printenv/testcgi written in 2 more languages.
394 To the extent that the usefulness is that it shows how to make scripts
395 of these types executable by httpd, I believe that the documentation
396 is the proper place to solve that. To the extent that the usefullness
397 is to show how to implement a CGI in these particular languages, I believe
398 that the httpd distribution and documentation in general is not the
399 place for that. Historically these types of scripts have caused problems
400 for downstream vendorsas well as newbies (and sometimes the intersection
401 of those two groups) who don't understand that these are information leaks
402 once they are enabled, and the subtlety of the way they are disabled ("Apache
403 messed up the first line; let me fix that") contributes to that.
404 fuankg notes: I've just added a big warning to all CGI scripts which should now
405 make absolutely clear that these CGIs are for testing purpose only - so those
406 who enable those scripts with inserting the right shebang should be 100% aware
407 of any risks (this should cover your last point).
408 jim: trawick, does the above address your concerns?
409 trawick: to some extent (somebody reading the script gets an idea)
410 Why isn't the configuration requirement documented instead
411 of described indirectly in a sample?
412 Why are these new samples added to the install without three
413 votes? (I didn't veto it; put your name next to the two
414 existing ones and I'll be satisified that enough people
415 considered this addition as an appropriate solution for a
416 real httpd usability problem.)
417 wrowe: I'd agree with trawick, and suggest that these scripts can begin
418 their life somewhere in the manual/ tree. This really seems like
419 the place where /usr/share/httpd/examples/ would be useful, but
420 there isn't an ordinary directory for that. Since we want none
421 of the scripts to function 'out of the box', what about a new
422 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
425 * core: block Define and Undefine in vhost and directory context. Because
426 it is EXEC_ON_READ, it "breaks out" of these contexts anyway.

430 +1: covener (I need to review the docs manually in this area)
431 -1: wrowe (blocking will break "working" .conf files on a subversion update
432 meant to pick up security fixes. "Alerting" I would agree to.)
