97 CURRENT RELEASE NOTES:
99 * Forward binary compatibility is expected of Apache 2.4.x releases, such
100 that no MMN major number changes will occur after 2.4.1. Such changes can
101 only be made in the trunk.
103 * All commits to branches/2.4.x must be reflected in SVN trunk,
104 as well, if they apply. Logical progression is commit to trunk
105 then merge into branches/2.4.x, as applicable.
107 * Current exceptions for RTC for this branch:
112 . non-Unix, single-platform code

125 AC_CONFIG_FILES list)
126 +1: jchampion, ylavic, jorton
129 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
130 [ New proposals should be added at the end of the list ]
132 *) mod_ssl: Return 502 instead of 500 when SSL peer check or
133 proxy_post_handshake hook fails.

135 2.4.x patch which adds CHANGES: https://emptyhammock.com/media/downloads/r1645529-to-2.4.x.txt
137 ylavic: there may be missing bits, see thread for commit r1736510.
139 *) core: Drop an invalid Last-Modified header value coming
140 from a (F)CGI script instead of replacing it with Unix epoch.
141 Warn the users about Last-Modified header value replacements
142 and violations of the RFC.

151 2.4.x: trunk patches works (final view http://apaste.info/FCs)
152 The last revision has been discussed extensively in dev@ and this seems to be
153 a good compromise for the moment.
154 Tested the code with a simple PHP script returning different Last-Modified
155 headers (GMT now, GMT now Europe/Paris, GMT tomorrow, GMT yesterday, PST now).
158 *) CMake: fix various issues for Windows/Visual Studio build environments.

162 http://svn.apache.org/r1752333
163 +1: jchampion, jim (by inspection)
165 *) mod_ssl: Fix quick renegotiation (OptRenegotiaton) with no intermediate
166 in the client certificate chain. PR 55786.
167 trunk patch: http://svn.apache.org/r1756542
168 2.4.x patch: trunk works (modulo CHANGES)
171 *) mod_cache: Use the actual URI path and query-string for identifying the
172 cached entity (key), such that rewrites are taken into account when
173 running afterwards (CacheQuickHandler off). PR 21935.
174 trunk patch: http://svn.apache.org/r1756553
175 http://svn.apache.org/r1756631
176 2.4.x patch: trunk works (modulo CHANGES)
179 *) mod_proxy_{http,ajp,fcgi}: don't reuse backend connections with data
180 available before the request is sent. PR 57832.
181 This also backports deprecation of ap_proxy_ssl_connection_cleanup() and
182 newly introduced proxy_conn->tmp_bb's usage in proxy code (both almost
183 related and immediate/simple follow ups, merge simplified by doing so).

210 2.4.x patch: http://home.apache.org/~ylavic/patches/httpd-2.4.x-r1702948_and_co.patch
213 *) mod_proxy_fcgi: read the whole FCGI response even for HTTP Precondition
214 failed (412) responses to avoid subsequent bogus reads and
215 confusing error messages logged.
216 trunk patch: http://svn.apache.org/r1759984
217 http://svn.apache.org/r1760018
218 2.4.x patch: trunk works
221 PATCHES/ISSUES THAT ARE BEING WORKED
223 *) http: Don't remove the Content-Length of zero from a HEAD response if
224 it comes from an origin server, module or script. Allow the previous
225 behaviour (for legacy/buggy modules only, not origin) by also backporting
226 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
227 comes for free with the same commit).
228 trunk patch: http://svn.apache.org/r1554303
229 http://svn.apache.org/r1678215
230 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
232 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
233 ints added at the end of core_server_config, the proposed merge
234 does a minor bump only.
235 minfrin: Two new directives need to be documented.
237 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
238 fetching the request body, so to minimize the delay between it is supposed
239 to be alive and the first bytes sent: this is a best effort to prevent the
240 backend from closing because of idle or keepalive timeout in the meantime.
241 Also, handle a new "proxy-flushall" environment variable which allows to
242 flush any forwarded body data immediately. PR 56541+37920.
243 trunk patch: http://svn.apache.org/r1656259
244 http://svn.apache.org/r1656359 (CHANGES entry)
245 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
247 -0: jim: This seems to be a hit to normal performance, to handle an
248 error and/or non-normal condition. The pre-fetch is
249 expensive, and is always done, even before we know that
250 the backend is available to rec' it. I understand the
251 error described, but is the fix actually worth it (plus
252 it seems to allow for a DDoS vector).
253 ylavic: It seems to me that the problem is real since we reuse the
254 connection before prefetching 16K (either controlled by the
255 client, or by an input filter), we currently always prefetch
256 these bytes already. Regarding performance I don't see any
257 difference (more cycles) compared with the current code.
258 However I think I failed to rebuild the header_brigade when
259 the proxy loop is retried (ping), so I need to rework this.
260 Do you think we'd better remove the prefetch, or maybe just
261 make it nonblocking (by default)?
262 jim: Non-blocking seems the best way to handle...
264 * mod_dav: Allow other modules to become providers and add ACLs
265 to the DAV response. Requires a release of apr-util v1.6.
266 trunk patch: http://svn.apache.org/r1748322
267 2.4.x: trunk works modulo CHANGES/MMN
269 rpluem asks: Will this compile with apr-util < v1.6 and keep
270 mod_dav working (without the new features of the patch of course)?
271 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
272 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
273 minfrin: Yes, as you can see in the patch everything applies only
274 if APR_XML_X2T_PARSED is defined, and the patch was tested with
275 both apr-util v1.6 and apr-util v1.5.
276 -1: jorton, breaks binary backwards compat per dev@ discuss
277 msgid <20160902120654.GA12674@redhat.com>
278 (& also, making the structure change with apr-util version
279 means it breaks binary compat across an apr-util upgrade?)
281 * mod_auth_digest: Reduce severity from NOTICE to DEBUG this
282 once-per-restart msg (I guess the concern was that the RNG
283 could block after this message)
285 AH01757: generating secret for digest authentication ...
287 trunk patch: This was fixed in trunk as a trivial part of http://svn.apache.org/r1492395
288 2.4.x patch: Just change the loglevel to DEBUG.
291 PATCHES/ISSUES THAT ARE STALLED
293 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
294 backport keeps syslog logging as part of httpd core and only adds
295 API to allow other modules to be used for error logging.
296 trunk patch: http://svn.apache.org/r1525597

307 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
309 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
310 needs 2 args which is not valid in ErrorLog manual)
311 trawick: nit: fix "writing" in "/* NULL if we are writing to syslog */"
312 (sorry, haven't finished reviewing completely)
313 jim: What is the status of this??
315 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
316 and ProxyMatch section to distinguish between normal workers and workers
317 with regex substitutions in the name. Implement handling of such workers
318 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
319 matched and used for request. PR 43513.
320 trunk patch: http://svn.apache.org/r1609680
321 http://svn.apache.org/r1609688
322 http://svn.apache.org/r1641381
323 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
324 Also added missing r1609688 to the patchset.
325 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
327 -0: covener tried to review this one in Austin with Jeff. Does the added match function
328 really cover a very narrow set of parameters with the way it skips over backreferences?
329 Also, why a new API vs. just setting the field inline?
331 * mod_systemd: New module, for integration with systemd on Linux.
332 trunk patch: http://svn.apache.org/r1393976

340 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
342 sf comments: The IdleShutdown logic seems broken. Consider a single
343 active connection that is stalled for 10 seconds. That
344 connection will be broken after GracefulShutdownTimeout.
345 A better logic would be to check if there is any open
346 connection that is not in keep-alive state.
348 * mod_journald: Add new module mod_journald to log error logs into journald.
349 This patch needs changes done in mod_systemd patch (already
351 trunk patch: http://svn.apache.org/r1610339

372 504 Gateway Timeout as opposed to 502 Bad Gateway
373 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
374 2.4.x patch: trunk patch works modulo CHANGES
376 -1: rpluem: This change is still disputed. See

379 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
380 compiled by the build compiler instead of the host compiler.
381 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

389 Moved fixing of shebang to separate target so that it is
390 no longer executed by default and all CGIs remain inactive.

394 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
397 This commit is essentially deciding that an httpd install on
398 Windows now has printenv/testcgi written in 2 more languages.
399 To the extent that the usefulness is that it shows how to make scripts
400 of these types executable by httpd, I believe that the documentation
401 is the proper place to solve that. To the extent that the usefullness
402 is to show how to implement a CGI in these particular languages, I believe
403 that the httpd distribution and documentation in general is not the
404 place for that. Historically these types of scripts have caused problems
405 for downstream vendorsas well as newbies (and sometimes the intersection
406 of those two groups) who don't understand that these are information leaks
407 once they are enabled, and the subtlety of the way they are disabled ("Apache
408 messed up the first line; let me fix that") contributes to that.
409 fuankg notes: I've just added a big warning to all CGI scripts which should now
410 make absolutely clear that these CGIs are for testing purpose only - so those
411 who enable those scripts with inserting the right shebang should be 100% aware
412 of any risks (this should cover your last point).
413 jim: trawick, does the above address your concerns?
414 trawick: to some extent (somebody reading the script gets an idea)
415 Why isn't the configuration requirement documented instead
416 of described indirectly in a sample?
417 Why are these new samples added to the install without three
418 votes? (I didn't veto it; put your name next to the two
419 existing ones and I'll be satisfied that enough people
420 considered this addition as an appropriate solution for a
421 real httpd usability problem.)
422 wrowe: I'd agree with trawick, and suggest that these scripts can begin
423 their life somewhere in the manual/ tree. This really seems like
424 the place where /usr/share/httpd/examples/ would be useful, but
425 there isn't an ordinary directory for that. Since we want none
426 of the scripts to function 'out of the box', what about a new
427 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
430 * core: block Define and Undefine in vhost and directory context. Because

432 trunk patch: http://svn.apache.org/r1656063
433 http://svn.apache.org/r1656122
434 2.4.x patch: http://people.apache.org/~covener/patches/2.4.x-define-limits.diff
435 +1: covener (I need to review the docs manually in this area)
436 -1: wrowe (blocking will break "working" .conf files on a subversion update
437 meant to pick up security fixes. "Alerting" I would agree to.)
