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

168 http://svn.apache.org/r1729930
169 http://svn.apache.org/r1729931
170 Trunk patch r1729930 applies, modulo CHANGES
171 Backport patch to r1729931 is noted in the commit log message
172 Requires r1729929 to be applied.
175 *) core: introducing new hook "pre_close_connection" to give protocols other
176 than http/1.1 a chance to send one last frame before close. Scoreboard
177 additions to allow update from master connections.
179 trunk patch: http://svn.apache.org/r1727071
180 http://svn.apache.org/r1727573
181 2.4.x patch: trunk works (modulo CHANGES)
182 covener: needs MMN bump, but sorting out previous MMN question first.
183 jim: Status, re: MMN bump ??
184 icing: I am embarrassingly bad at this. I propose to include the scoreboard
185 additions into this bump and propose all this together. So the new
186 proposal is (including an old apr_time_now() optimization from jim
187 for scorebaord.c). And that now includes all backports necessary to
188 update mod_http2 in 2.4.x:
190 http://svn.apache.org/r1417440

195 http://svn.apache.org/r1729376
196 http://svn.apache.org/r1729960
197 2.4.x patch: trunk works (modulo CHANGES)
200 rpluem says: +1, but I would like to see http://svn.apache.org/r1730865 added.
202 *) mod_proxy_wstunnel, mod_proxy_connect: Use the correct pool and allocator
203 lifetime when sending brigades and buckets down the filter chain to the
204 backend and the client in mod_proxy_wstunnel and mod_proxy_connect.

217 Backport version for 2.4.x of patch:
218 http://home.apache.org/~rpluem/patches/proxy_correctlifetime.diff
221 PATCHES/ISSUES THAT ARE BEING WORKED
223 * core: Fix crash in ap_mpm_pod_check call caused by NULL dereference of
224 its parameter when starting httpd as single process (httpd -X).
225 trunk patch: http://svn.apache.org/r1711479
226 2.4.x patch: trunk works
228 minfrin: Needs extra parens to suppress a warning:
229 prefork.c:1319:16: note: place parentheses around the assignment
230 to silence this warning
231 jailletc36: This has been done in r1711919
232 ylavic: Also, I don't think the changes on worker/event are needed,
233 only prefork requires the accept mutex in ONE_PROCESS mode.
235 *) http: Don't remove the Content-Length of zero from a HEAD response if
236 it comes from an origin server, module or script. Allow the previous
237 behaviour (for legacy/buggy modules only, not origin) by also backporting
238 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
239 comes for free with the same commit).
240 trunk patch: http://svn.apache.org/r1554303
241 http://svn.apache.org/r1678215
242 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
244 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
245 ints added at the end of core_server_config, the proposed merge
246 does a minor bump only.
247 minfrin: Two new directives need to be documented.
249 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
250 fetching the request body, so to minimize the delay between it is supposed
251 to be alive and the first bytes sent: this is a best effort to prevent the
252 backend from closing because of idle or keepalive timeout in the meantime.
253 Also, handle a new "proxy-flushall" environment variable which allows to
254 flush any forwarded body data immediately. PR 56541+37920.
255 trunk patch: http://svn.apache.org/r1656259
256 http://svn.apache.org/r1656359 (CHANGES entry)
257 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
259 -0: jim: This seems to be a hit to normal performance, to handle an
260 error and/or non-normal condition. The pre-fetch is
261 expensive, and is always done, even before we know that
262 the backend is available to rec' it. I understand the
263 error described, but is the fix actually worth it (plus
264 it seems to allow for a DDoS vector).
265 ylavic: It seems to me that the problem is real since we reuse the
266 connection before prefetching 16K (either controlled by the
267 client, or by an input filter), we currently always prefetch
268 these bytes already. Regarding performance I don't see any
269 difference (more cycles) compared with the current code.
270 However I think I failed to rebuild the header_brigade when
271 the proxy loop is retried (ping), so I need to rework this.
272 Do you think we'd better remove the prefetch, or maybe just
273 make it nonblocking (by default)?
274 jim: Non-blocking seems the best way to handle...
276 PATCHES/ISSUES THAT ARE STALLED
278 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
279 backport keeps syslog logging as part of httpd core and only adds
280 API to allow other modules to be used for error logging.

291 http://svn.apache.org/r1626978
292 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
294 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
295 needs 2 args which is not valid in ErrorLog manual)
296 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
297 (sorry, haven't finished reviewing completely)
298 jim: What is the status of this??
300 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
301 and ProxyMatch section to distinguish between normal workers and workers
302 with regex substitutions in the name. Implement handling of such workers
303 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
304 matched and used for request. PR 43513.
305 trunk patch: http://svn.apache.org/r1609680
306 http://svn.apache.org/r1609688
307 http://svn.apache.org/r1641381
308 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
309 Also added missing r1609688 to the patchset.
310 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
312 -0: covener tried to review this one in Austin with Jeff. Does the added match function
313 really cover a very narrow set of parameters with the way it skips over backreferences?
314 Also, why a new API vs. just setting the field inline?
316 * mod_systemd: New module, for integration with systemd on Linux.

325 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
328 * mod_journald: Add new module mod_journald to log error logs into journald.
329 This patch needs changes done in mod_systemd patch (already
331 trunk patch: http://svn.apache.org/r1610339

333 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
335 rjung, minfrin: Not understanding "This patch needs changes done in
336 mod_systemd patch", am I right in understanding this patch is
338 jkaluza: No, that patch is not committed yet. It is in STALLED section.
339 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
341 * core: Add support for systemd socket activation.

348 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
351 * mod_proxy: Ensure network errors detected by the proxy are returned as
352 504 Gateway Timout as opposed to 502 Bad Gateway
353 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
354 2.4.x patch: trunk patch works modulo CHANGES
356 -1: rpluem: This change is still disputed. See

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

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

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