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. ]
112 *) mod_authz_dbd: Avoid a crash when lacking correct DB access permissions.
114 trunk: http://svn.apache.org/r1688660
115 2.4.x: trunk works modulo CHANGES and next-number
116 +1: jailletc36, ylavic, niq
117 jailletc36: I'm just wondering why the log message speak about "dbd-query"
118 while other messages around are about "dbd-group"?
120 *) mod_rewrite: Avoid a crash when lacking correct DB access permissions
121 when using RewriteMap with MapType dbd or fastdbd.
123 trunk: http://svn.apache.org/r1695170
124 2.4.x: trunk works modulo (missing) CHANGES and next-number
125 +1: jailletc36, ylavic, niq
126 jailletc36: A CHANGE entry should be added. I forgot it :(
128 *) mod_dir: when we bail out of fixups, make sure Content-Type is not still
129 httpd/unix-directory. This only happens when the generator sets
130 no content-type which is more common w/ no DefaultType in 2.4.
131 trunk: http://svn.apache.org/r1695583
133 +1: covener, ylavic, niq
135 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
136 [ New proposals should be added at the end of the list ]
138 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
139 and ProxyMatch section to distinguish between normal workers and workers
140 with regex substitutions in the name. Implement handling of such workers
141 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
142 matched and used for request. PR 43513.
143 trunk patch: http://svn.apache.org/r1609680
144 http://svn.apache.org/r1609688
145 http://svn.apache.org/r1641381
146 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
147 Also added missing r1609688 to the patchset.
148 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
150 -0: covener tried to review this one in Austin with Jeff. Does the added match function
151 really cover a very narrow set of parameters with the way it skips over backreferences?
152 Also, why a new API vs. just setting the field inline?
154 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
155 backport keeps syslog logging as part of httpd core and only adds
156 API to allow other modules to be used for error logging.

168 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
170 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
171 needs 2 args which is not valid in ErrorLog manual)
172 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
173 (sorry, haven't finished reviewing completely)
175 * mod_journald: Add new module mod_journald to log error logs into journald.

202 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_listeners_buckets-v3.patch
205 *) http: Don't remove the Content-Length of zero from a HEAD response if
206 it comes from an origin server, module or script. Allow the previous
207 behaviour (for legacy/buggy modules only, not origin) by also backporting
208 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
209 comes for free with the same commit).

212 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
214 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
215 ints added at the end of core_server_config, the proposed merge
216 does a minor bump only.

240 niq: 1. the if(worker->s->retries) {} and comment at line 2917
241 don't seem to make any sense.
242 rpluem: This is just taken over from existing code. It is just indented
243 differently hence part of the path I think it should be marked
244 as TODO section. But this should be subject to another
246 2. Re: error handline line 2930 - can PROXY_WORKER_IS_USABLE
247 not be tested BEFORE opening connection?
248 rpluem: We could, but we can catch more race cases with the current code
249 as it also catches the case where a connection establishment
250 took long and the worker went into error meanwhile.

285 2.4.x: trunk works (modulo CHANGES and log-message-tags)
288 *) mod_proxy: Give ap_proxy_post_request as chance to act correctly on the status code
289 by setting r->status temporarily to access_status. r->status might be different than
290 access_status e.g. r->status could be HTTP_OK if e.g. we override the error page on

323 Let's comment on @dev for Stefan Eissing (mod_h2) to be able to
326 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
327 fetching the request body, so to minimize the delay between it is supposed
328 to be alive and the first bytes sent: this is a best effort to prevent the
329 backend from closing because of idle or keepalive timeout in the meantime.
330 Also, handle a new "proxy-flushall" environment variable which allows to
331 flush any forwarded body data immediately. PR 56541+37920.
332 trunk patch: http://svn.apache.org/r1656259
333 http://svn.apache.org/r1656359 (CHANGES entry)
334 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
336 -0: jim: This seems to be a hit to normal performance, to handle an
337 error and/or non-normal condition. The pre-fetch is
338 expensive, and is always done, even before we know that
339 the backend is available to rec' it. I understand the
340 error described, but is the fix actually worth it (plus
341 it seems to allow for a DDoS vector).
342 ylavic: It seems to me that the problem is real since we reuse the
343 connection before prefetching 16K (either controlled by the
344 client, or by an input filter), we currently always prefetch
345 these bytes already. Regarding performance I don't see any
346 difference (more cycles) compared with the current code.
347 However I think I failed to rebuild the header_brigade when
348 the proxy loop is retried (ping), so I need to rework this.
349 Do you think we'd better remove the prefetch, or maybe just
350 make it nonblocking (by default)?
351 jim: Non-blocking seems the best way to handle...

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