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:
104 . non-Unix, single-platform code
106 RELEASE SHOWSTOPPERS:
109 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
110 [ start all new proposals below, under PATCHES PROPOSED. ]
113 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
114 [ New proposals should be added at the end of the list ]
116 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
117 and ProxyMatch section to distinguish between normal workers and workers
118 with regex substitutions in the name. Implement handling of such workers
119 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
120 matched and used for request. PR 43513.

123 http://svn.apache.org/r1641381
124 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
125 Also added missing r1609688 to the patchset.
126 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
128 -0: covener tried to review this one in Austin with Jeff. Does the added match function
129 really cover a very narrow set of parameters with the way it skips over backreferences?
130 Also, why a new API vs. just setting the field inline?
132 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
133 backport keeps syslog logging as part of httpd core and only adds
134 API to allow other modules to be used for error logging.

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

192 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
193 ints added at the end of core_server_config, the proposed merge
194 does a minor bump only.

243 httpd/unix-directory. This only happens when the generator sets

280 Let's comment on @dev for Stefan Eissing (mod_h2) to be able to
283 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
284 fetching the request body, so to minimize the delay between it is supposed
285 to be alive and the first bytes sent: this is a best effort to prevent the
286 backend from closing because of idle or keepalive timeout in the meantime.
287 Also, handle a new "proxy-flushall" environment variable which allows to
288 flush any forwarded body data immediately. PR 56541+37920.
289 trunk patch: http://svn.apache.org/r1656259
290 http://svn.apache.org/r1656359 (CHANGES entry)
291 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
293 -0: jim: This seems to be a hit to normal performance, to handle an
294 error and/or non-normal condition. The pre-fetch is
295 expensive, and is always done, even before we know that
296 the backend is available to rec' it. I understand the
297 error described, but is the fix actually worth it (plus
298 it seems to allow for a DDoS vector).
299 ylavic: It seems to me that the problem is real since we reuse the
300 connection before prefetching 16K (either controlled by the
301 client, or by an input filter), we currently always prefetch
302 these bytes already. Regarding performance I don't see any
303 difference (more cycles) compared with the current code.
304 However I think I failed to rebuild the header_brigade when
305 the proxy loop is retried (ping), so I need to rework this.
306 Do you think we'd better remove the prefetch, or maybe just
307 make it nonblocking (by default)?
308 jim: Non-blocking seems the best way to handle...

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