90 CURRENT RELEASE NOTES:
92 * Forward binary compatibility is expected of Apache 2.4.x releases, such
93 that no MMN major number changes will occur after 2.4.1. Such changes can
94 only be made in the trunk.
96 * All commits to branches/2.4.x must be reflected in SVN trunk,
97 as well, if they apply. Logical progression is commit to trunk
98 then merge into branches/2.4.x, as applicable.
100 * Current exceptions for RTC for this branch:
105 . non-Unix, single-platform code
107 RELEASE SHOWSTOPPERS:
110 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
111 [ start all new proposals below, under PATCHES PROPOSED. ]
116 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
117 [ New proposals should be added at the end of the list ]
119 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
120 backport keeps syslog logging as part of httpd core and only adds
121 API to allow other modules to be used for error logging.

152 *) http: Don't remove the Content-Length of zero from a HEAD response if
153 it comes from an origin server, module or script. Allow the previous
154 behaviour (for legacy/buggy modules only, not origin) by also backporting
155 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
156 comes for free with the same commit).

158 http://svn.apache.org/r1678215
159 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
161 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
162 ints added at the end of core_server_config, the proposed merge
163 does a minor bump only.
164 minfrin: Two new directives need to be documented.

186 2.4.x patch: trunk works (module CHANGES)
188 ylavic: while at it, I also included r1678763 which is only an
189 optimization, but allows to keep code in sync with trunk.
191 *) mod_alias: Introduce expression parser support for Alias, ScriptAlias
192 and Redirect. Limit Redirect expressions to directory (Location) context
193 and redirect statuses (implicit or explicit).

237 2.4.x patch: trunk works
240 PATCHES/ISSUES THAT ARE BEING WORKED
242 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
243 fetching the request body, so to minimize the delay between it is supposed
244 to be alive and the first bytes sent: this is a best effort to prevent the
245 backend from closing because of idle or keepalive timeout in the meantime.
246 Also, handle a new "proxy-flushall" environment variable which allows to
247 flush any forwarded body data immediately. PR 56541+37920.
248 trunk patch: http://svn.apache.org/r1656259
249 http://svn.apache.org/r1656359 (CHANGES entry)
250 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
252 -0: jim: This seems to be a hit to normal performance, to handle an
253 error and/or non-normal condition. The pre-fetch is
254 expensive, and is always done, even before we know that
255 the backend is available to rec' it. I understand the
256 error described, but is the fix actually worth it (plus
257 it seems to allow for a DDoS vector).
258 ylavic: It seems to me that the problem is real since we reuse the
259 connection before prefetching 16K (either controlled by the
260 client, or by an input filter), we currently always prefetch
261 these bytes already. Regarding performance I don't see any
262 difference (more cycles) compared with the current code.
263 However I think I failed to rebuild the header_brigade when
264 the proxy loop is retried (ping), so I need to rework this.
265 Do you think we'd better remove the prefetch, or maybe just
266 make it nonblocking (by default)?
267 jim: Non-blocking seems the best way to handle...
269 PATCHES/ISSUES THAT ARE STALLED
271 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
272 and ProxyMatch section to distinguish between normal workers and workers
273 with regex substitutions in the name. Implement handling of such workers
274 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
275 matched and used for request. PR 43513.
276 trunk patch: http://svn.apache.org/r1609680
277 http://svn.apache.org/r1609688
278 http://svn.apache.org/r1641381
279 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
280 Also added missing r1609688 to the patchset.
281 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
283 -0: covener tried to review this one in Austin with Jeff. Does the added match function
284 really cover a very narrow set of parameters with the way it skips over backreferences?
285 Also, why a new API vs. just setting the field inline?
287 * mod_systemd: New module, for integration with systemd on Linux.
288 trunk patch: http://svn.apache.org/r1393976

296 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
299 * core: Add support for systemd socket activation.

306 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
309 * mod_proxy: Ensure network errors detected by the proxy are returned as
310 504 Gateway Timout as opposed to 502 Bad Gateway
311 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
312 2.4.x patch: trunk patch works modulo CHANGES
314 -1: rpluem: This change is still disputed. See
315 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
317 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
318 compiled by the build compiler instead of the host compiler.
319 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

332 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
335 This commit is essentially deciding that an httpd install on
336 Windows now has printenv/testcgi written in 2 more languages.
337 To the extent that the usefulness is that it shows how to make scripts
338 of these types executable by httpd, I believe that the documentation
339 is the proper place to solve that. To the extent that the usefullness
340 is to show how to implement a CGI in these particular languages, I believe
341 that the httpd distribution and documentation in general is not the
342 place for that. Historically these types of scripts have caused problems
343 for downstream vendorsas well as newbies (and sometimes the intersection
344 of those two groups) who don't understand that these are information leaks
345 once they are enabled, and the subtlety of the way they are disabled ("Apache
346 messed up the first line; let me fix that") contributes to that.
347 fuankg notes: I've just added a big warning to all CGI scripts which should now
348 make absolutely clear that these CGIs are for testing purpose only - so those
349 who enable those scripts with inserting the right shebang should be 100% aware
350 of any risks (this should cover your last point).
351 jim: trawick, does the above address your concerns?
352 trawick: to some extent (somebody reading the script gets an idea)
353 Why isn't the configuration requirement documented instead
354 of described indirectly in a sample?
355 Why are these new samples added to the install without three
356 votes? (I didn't veto it; put your name next to the two
357 existing ones and I'll be satisified that enough people
358 considered this addition as an appropriate solution for a
359 real httpd usability problem.)
360 wrowe: I'd agree with trawick, and suggest that these scripts can begin
361 their life somewhere in the manual/ tree. This really seems like
362 the place where /usr/share/httpd/examples/ would be useful, but
363 there isn't an ordinary directory for that. Since we want none
364 of the scripts to function 'out of the box', what about a new
365 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
