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

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.

121 http://svn.apache.org/r1609688
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.

183 it comes from an origin server, module or script. Allow the previous
184 behaviour (for legacy/buggy modules only, not origin) by also backporting
185 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which

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

233 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
234 fetching the request body, so to minimize the delay between it is supposed
235 to be alive and the first bytes sent: this is a best effort to prevent the
236 backend from closing because of idle or keepalive timeout in the meantime.
237 Also, handle a new "proxy-flushall" environment variable which allows to
238 flush any forwarded body data immediately. PR 56541+37920.
239 trunk patch: http://svn.apache.org/r1656259
240 http://svn.apache.org/r1656359 (CHANGES entry)
241 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
243 -0: jim: This seems to be a hit to normal performance, to handle an
244 error and/or non-normal condition. The pre-fetch is
245 expensive, and is always done, even before we know that
246 the backend is available to rec' it. I understand the
247 error described, but is the fix actually worth it (plus
248 it seems to allow for a DDoS vector).
249 ylavic: It seems to me that the problem is real since we reuse the
250 connection before prefetching 16K (either controlled by the
251 client, or by an input filter), we currently always prefetch
252 these bytes already. Regarding performance I don't see any
253 difference (more cycles) compared with the current code.
254 However I think I failed to rebuild the header_brigade when
255 the proxy loop is retried (ping), so I need to rework this.
256 Do you think we'd better remove the prefetch, or maybe just
257 make it nonblocking (by default)?
258 jim: Non-blocking seems the best way to handle...

308 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
311 This commit is essentially deciding that an httpd install on
312 Windows now has printenv/testcgi written in 2 more languages.
313 To the extent that the usefulness is that it shows how to make scripts
314 of these types executable by httpd, I believe that the documentation
315 is the proper place to solve that. To the extent that the usefullness
316 is to show how to implement a CGI in these particular languages, I believe
317 that the httpd distribution and documentation in general is not the
318 place for that. Historically these types of scripts have caused problems
319 for downstream vendorsas well as newbies (and sometimes the intersection
320 of those two groups) who don't understand that these are information leaks
321 once they are enabled, and the subtlety of the way they are disabled ("Apache
322 messed up the first line; let me fix that") contributes to that.
323 fuankg notes: I've just added a big warning to all CGI scripts which should now
324 make absolutely clear that these CGIs are for testing purpose only - so those
325 who enable those scripts with inserting the right shebang should be 100% aware
326 of any risks (this should cover your last point).
327 jim: trawick, does the above address your concerns?
328 trawick: to some extent (somebody reading the script gets an idea)
329 Why isn't the configuration requirement documented instead
330 of described indirectly in a sample?
331 Why are these new samples added to the install without three
332 votes? (I didn't veto it; put your name next to the two
333 existing ones and I'll be satisified that enough people
334 considered this addition as an appropriate solution for a
335 real httpd usability problem.)
336 wrowe: I'd agree with trawick, and suggest that these scripts can begin
337 their life somewhere in the manual/ tree. This really seems like
338 the place where /usr/share/httpd/examples/ would be useful, but
339 there isn't an ordinary directory for that. Since we want none
340 of the scripts to function 'out of the box', what about a new
341 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
