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

189 http://svn.apache.org/r1727573
190 2.4.x patch: trunk works (modulo CHANGES)
191 covener: needs MMN bump, but sorting out previous MMN question first.
192 jim: Status, re: MMN bump ??
193 icing: I am embarrassingly bad at this. I propose to include the scoreboard
194 additions into this bump and propose all this together. So the new
195 proposal is (including an old apr_time_now() optimization from jim
196 for scorebaord.c). And that now includes all backports necessary to
197 update mod_http2 in 2.4.x:

224 trunk patch: http://svn.apache.org/r1727842
225 2.4.x patch: trunk works
226 +1: jailletc36, jim, rpluem
228 *) mod_proxy_wstunnel, mod_proxy_connect: Use the correct pool and allocator
229 lifetime when sending brigades and buckets down the filter chain to the
230 backend and the client in mod_proxy_wstunnel and mod_proxy_connect.

244 http://home.apache.org/~rpluem/patches/proxy_correctlifetime.diff
247 PATCHES/ISSUES THAT ARE BEING WORKED
249 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
250 its parameter when starting httpd as single process (httpd -X).
251 trunk patch: http://svn.apache.org/r1711479
252 2.4.x patch: trunk works
254 minfrin: Needs extra parens to suppress a warning:
255 prefork.c:1319:16: note: place parentheses around the assignment
256 to silence this warning
257 jailletc36: This has been done in r1711919
258 ylavic: Also, I don't think the changes on worker/event are needed,
259 only prefork requires the accept mutex in ONE_PROCESS mode.
261 *) http: Don't remove the Content-Length of zero from a HEAD response if
262 it comes from an origin server, module or script. Allow the previous
263 behaviour (for legacy/buggy modules only, not origin) by also backporting
264 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
265 comes for free with the same commit).
266 trunk patch: http://svn.apache.org/r1554303
267 http://svn.apache.org/r1678215
268 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
270 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
271 ints added at the end of core_server_config, the proposed merge
272 does a minor bump only.
273 minfrin: Two new directives need to be documented.
275 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
276 fetching the request body, so to minimize the delay between it is supposed
277 to be alive and the first bytes sent: this is a best effort to prevent the
278 backend from closing because of idle or keepalive timeout in the meantime.
279 Also, handle a new "proxy-flushall" environment variable which allows to
280 flush any forwarded body data immediately. PR 56541+37920.
281 trunk patch: http://svn.apache.org/r1656259
282 http://svn.apache.org/r1656359 (CHANGES entry)
283 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
285 -0: jim: This seems to be a hit to normal performance, to handle an
286 error and/or non-normal condition. The pre-fetch is
287 expensive, and is always done, even before we know that
288 the backend is available to rec' it. I understand the
289 error described, but is the fix actually worth it (plus
290 it seems to allow for a DDoS vector).
291 ylavic: It seems to me that the problem is real since we reuse the
292 connection before prefetching 16K (either controlled by the
293 client, or by an input filter), we currently always prefetch
294 these bytes already. Regarding performance I don't see any
295 difference (more cycles) compared with the current code.
296 However I think I failed to rebuild the header_brigade when
297 the proxy loop is retried (ping), so I need to rework this.
298 Do you think we'd better remove the prefetch, or maybe just
299 make it nonblocking (by default)?
300 jim: Non-blocking seems the best way to handle...
302 PATCHES/ISSUES THAT ARE STALLED
304 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
305 backport keeps syslog logging as part of httpd core and only adds
306 API to allow other modules to be used for error logging.

317 http://svn.apache.org/r1626978
318 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
320 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
321 needs 2 args which is not valid in ErrorLog manual)
322 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
323 (sorry, haven't finished reviewing completely)
324 jim: What is the status of this??
326 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
327 and ProxyMatch section to distinguish between normal workers and workers
328 with regex substitutions in the name. Implement handling of such workers
329 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
330 matched and used for request. PR 43513.
331 trunk patch: http://svn.apache.org/r1609680
332 http://svn.apache.org/r1609688
333 http://svn.apache.org/r1641381
334 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
335 Also added missing r1609688 to the patchset.
336 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
338 -0: covener tried to review this one in Austin with Jeff. Does the added match function
339 really cover a very narrow set of parameters with the way it skips over backreferences?
340 Also, why a new API vs. just setting the field inline?
342 * mod_systemd: New module, for integration with systemd on Linux.

351 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
354 * mod_journald: Add new module mod_journald to log error logs into journald.
355 This patch needs changes done in mod_systemd patch (already

364 jkaluza: No, that patch is not committed yet. It is in STALLED section.
365 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch

379 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
380 2.4.x patch: trunk patch works modulo CHANGES

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

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

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