89 CURRENT RELEASE NOTES:
91 * Forward binary compatibility is expected of Apache 2.4.x releases, such
92 that no MMN major number changes will occur after 2.4.1. Such changes can
93 only be made in the trunk.
95 * All commits to branches/2.4.x must be reflected in SVN trunk,
96 as well, if they apply. Logical progression is commit to trunk
97 then merge into branches/2.4.x, as applicable.
99 * Current exceptions for RTC for this branch:
103 . non-Unix, single-platform code
105 RELEASE SHOWSTOPPERS:
108 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
109 [ start all new proposals below, under PATCHES PROPOSED. ]
112 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
113 [ New proposals should be added at the end of the list ]
115 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
116 and ProxyMatch section to distinguish between normal workers and workers
117 with regex substitutions in the name. Implement handling of such workers
118 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
119 matched and used for request. PR 43513.

122 http://svn.apache.org/r1641381
123 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
124 Also added missing r1609688 to the patchset.
125 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
127 -0: covener tried to review this one in Austin with Jeff. Does the added match function
128 really cover a very narrow set of parameters with the way it skips over backreferences?
129 Also, why a new API vs. just setting the field inline?
131 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
132 backport keeps syslog logging as part of httpd core and only adds
133 API to allow other modules to be used for error logging.

147 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
148 needs 2 args which is not valid in ErrorLog manual)

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

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

248 Let's comment on @dev for Stefan Eissing (mod_h2) to be able to
251 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
252 fetching the request body, so to minimize the delay between it is supposed
253 to be alive and the first bytes sent: this is a best effort to prevent the
254 backend from closing because of idle or keepalive timeout in the meantime.
255 Also, handle a new "proxy-flushall" environment variable which allows to
256 flush any forwarded body data immediately. PR 56541+37920.
257 trunk patch: http://svn.apache.org/r1656259
258 http://svn.apache.org/r1656359 (CHANGES entry)
259 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
261 -0: jim: This seems to be a hit to normal performance, to handle an
262 error and/or non-normal condition. The pre-fetch is
263 expensive, and is always done, even before we know that
264 the backend is available to rec' it. I understand the
265 error described, but is the fix actually worth it (plus
266 it seems to allow for a DDoS vector).
267 ylavic: It seems to me that the problem is real since we reuse the
268 connection before prefetching 16K (either controlled by the
269 client, or by an input filter), we currently always prefetch
270 these bytes already. Regarding performance I don't see any
271 difference (more cycles) compared with the current code.
272 However I think I failed to rebuild the header_brigade when
273 the proxy loop is retried (ping), so I need to rework this.
274 Do you think we'd better remove the prefetch, or maybe just
275 make it nonblocking (by default)?
276 jim: Non-blocking seems the best way to handle...

326 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
329 This commit is essentially deciding that an httpd install on
330 Windows now has printenv/testcgi written in 2 more languages.
331 To the extent that the usefulness is that it shows how to make scripts
332 of these types executable by httpd, I believe that the documentation
333 is the proper place to solve that. To the extent that the usefullness
334 is to show how to implement a CGI in these particular languages, I believe
335 that the httpd distribution and documentation in general is not the
336 place for that. Historically these types of scripts have caused problems
337 for downstream vendorsas well as newbies (and sometimes the intersection
338 of those two groups) who don't understand that these are information leaks
339 once they are enabled, and the subtlety of the way they are disabled ("Apache
340 messed up the first line; let me fix that") contributes to that.
341 fuankg notes: I've just added a big warning to all CGI scripts which should now
342 make absolutely clear that these CGIs are for testing purpose only - so those
343 who enable those scripts with inserting the right shebang should be 100% aware
344 of any risks (this should cover your last point).
345 jim: trawick, does the above address your concerns?
346 trawick: to some extent (somebody reading the script gets an idea)
347 Why isn't the configuration requirement documented instead
348 of described indirectly in a sample?
349 Why are these new samples added to the install without three
350 votes? (I didn't veto it; put your name next to the two
351 existing ones and I'll be satisified that enough people
352 considered this addition as an appropriate solution for a
353 real httpd usability problem.)
354 wrowe: I'd agree with trawick, and suggest that these scripts can begin
355 their life somewhere in the manual/ tree. This really seems like
356 the place where /usr/share/httpd/examples/ would be useful, but
357 there isn't an ordinary directory for that. Since we want none
358 of the scripts to function 'out of the box', what about a new
359 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
