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

152 wrowe asks: Can we capitalize Verify in SSLOCSPNoverify to keep
154 ylavic: +1 with http://svn.apache.org/r1788430, fixing the merge of

165 2.4.x patch: trunk works *after r1779573 above* (modulo CHANGES)
166 FULL hcheck patch: http://home.apache.org/~jim/patches/httpd2.4-hcheck.patch
167 (includes all hcheck related patches, including showstopper)
169 ylavic: 'tpsize' needs to be reset (to HC_THREADPOOL_SIZE) in pre_config,
170 otherwise if mod_proxy_hcheck is builtin/static and for example
171 ProxyHCTPsize were commented out on restart, we wouldn't use the
172 default value (as expected).
174 *) mod_autoindex: Add IndexOptions UseOldDateFormat to allow the date
175 format from 2.2 in the Last Modified column. PR60846.

177 http://svn.apache.org/r1787553
178 http://svn.apache.org/r1788451
179 2.4.x patch: trunk works
182 *) mod_proxy: Allow the per-request environment variable "no-proxy" to
183 be used as an alternative to ProxyPass /path !. This is primarily
184 to set exceptions for ProxyPass specified in <Location> context.
185 trunk patch: http://svn.apache.org/r1781328
186 http://svn.apache.org/r1785907

201 2.4.x patch: trunk patches work
202 +1: jailletc36, ylavic
204 *) core: Disallow multiple Listen on the same IP:port when listener buckets
205 are configured (ListenCoresBucketsRatio > 0), consistently with the single
206 bucket case (default), thus avoiding the leak of the corresponding socket
207 descriptors on graceful restart.
208 trunk patch: http://svn.apache.org/r1789220
209 2.4.x patch: trunk works (modulo CHANGES)

224 2.4.x patch: http://home.apache.org/~jim/patches/brotli-2.4.patch
226 -1: wrowe (Premature, waiting on github.com/google/brotli 0.6 release)
227 NOTE: Awaiting next release post 0.5.2
229 *) mod_remoteip: Add PROXY protocol support
230 trunk patch: http://svn.apache.org/r1776575

241 2.4 convenience patch (includes CHANGES):
242 http://people.apache.org/~druggeri/patches/RemoteIPProxyProtocol.2.4.x.patch
244 -0.5: wrowe (Still reviewing support of unwise 'optional' schema vs. other
245 possibile solves; questioning reading-but-ignoring PROXY
246 protocol input, also seems unwise)
248 *) mod_ssl: Return 502 instead of 500 when SSL peer check or
249 proxy_post_handshake hook fails.
250 Trunk patch: r1645529 (works)
251 2.4.x patch which adds CHANGES: https://emptyhammock.com/media/downloads/r1645529-to-2.4.x.txt
253 ylavic: there may be missing bits, see thread for commit r1736510.
255 *) core: Drop an invalid Last-Modified header value coming
256 from a (F)CGI script instead of replacing it with Unix epoch.
257 Warn the users about Last-Modified header value replacements
258 and violations of the RFC.
259 trunk patch: http://svn.apache.org/r1748379
260 http://svn.apache.org/r1750747
261 http://svn.apache.org/r1750749

267 2.4.x: trunk patches work, final view:
268 http://home.apache.org/~elukey/httpd-2.4.x-core-last_modified_tz_logging.patch
269 The problem has been discussed in dev@ extensively but we did not reach a common
270 agreement about how to proceed in the long term. While we wait, I would really like
271 to introduce useful logs for the users (the starting point of this change was a users@
272 email thread). If this is not the right way to go I will move the patch to other
273 sections of STATUS (stalled or being worked).
274 The code has been tested with a simple PHP script returning different Last-Modified
275 headers (GMT now, GMT now Europe/Paris, GMT tomorrow, GMT yesterday, PST now).
278 *) http: Don't remove the Content-Length of zero from a HEAD response if
279 it comes from an origin server, module or script. Allow the previous
280 behaviour (for legacy/buggy modules only, not origin) by also backporting
281 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
282 comes for free with the same commit).
283 trunk patch: http://svn.apache.org/r1554303
284 http://svn.apache.org/r1678215
285 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
287 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
288 ints added at the end of core_server_config, the proposed merge
289 does a minor bump only.
290 minfrin: Two new directives need to be documented.
292 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
293 fetching the request body, so to minimize the delay between it is supposed
294 to be alive and the first bytes sent: this is a best effort to prevent the
295 backend from closing because of idle or keepalive timeout in the meantime.
296 Also, handle a new "proxy-flushall" environment variable which allows to
297 flush any forwarded body data immediately. PR 56541+37920.
298 trunk patch: http://svn.apache.org/r1656259
299 http://svn.apache.org/r1656359 (CHANGES entry)
300 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
302 -0: jim: This seems to be a hit to normal performance, to handle an
303 error and/or non-normal condition. The pre-fetch is
304 expensive, and is always done, even before we know that
305 the backend is available to rec' it. I understand the
306 error described, but is the fix actually worth it (plus
307 it seems to allow for a DDoS vector).
308 ylavic: It seems to me that the problem is real since we reuse the
309 connection before prefetching 16K (either controlled by the
310 client, or by an input filter), we currently always prefetch
311 these bytes already. Regarding performance I don't see any
312 difference (more cycles) compared with the current code.
313 However I think I failed to rebuild the header_brigade when
314 the proxy loop is retried (ping), so I need to rework this.
315 Do you think we'd better remove the prefetch, or maybe just
316 make it nonblocking (by default)?
317 jim: Non-blocking seems the best way to handle...
319 * mod_dav: Allow other modules to become providers and add ACLs
320 to the DAV response. Requires a release of apr-util v1.6.
321 trunk patch: http://svn.apache.org/r1748322
322 2.4.x: trunk works modulo CHANGES/MMN
324 rpluem asks: Will this compile with apr-util < v1.6 and keep
325 mod_dav working (without the new features of the patch of course)?
326 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
327 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
328 minfrin: Yes, as you can see in the patch everything applies only
329 if APR_XML_X2T_PARSED is defined, and the patch was tested with
330 both apr-util v1.6 and apr-util v1.5.
331 -1: jorton, breaks binary backwards compat per dev@ discuss
332 msgid <20160902120654.GA12674@redhat.com>
333 (& also, making the structure change with apr-util version
334 means it breaks binary compat across an apr-util upgrade?)
336 * Support PCRE2 (10.x) in place of PCRE (8.x).
337 Submitted by: wrowe, Petr Pisar [ppisar redhat.com]

343 http://svn.apache.org/r1773870
344 http://svn.apache.org/r1773882
345 wrowe notes that the current code is too inefficient, owing to the fact
346 that the ovector is a required allocation and is no longer allocated on
347 the stack, by design. The correct fix is an apr userdata allocation on
348 the appropriate pool, which would be thread-safe, but the actual API of
349 ap_regexec[_len]() offers us no pool. We cannot associate that pool with
350 the ap_regex_t, because a single regex may be used by many threads in
351 parallel and is not thread-safe beyond initialization.
352 So the only fix allowing us to use PCRE 10 in httpd 2.4 would be to write
353 this as a thread safe storage buffer for the majority of cases (<10 $args)
354 and we don't have a portable tls mechanism to do so.
357 PATCHES/ISSUES THAT ARE STALLED
359 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
360 backport keeps syslog logging as part of httpd core and only adds
361 API to allow other modules to be used for error logging.
362 trunk patch: http://svn.apache.org/r1525597

373 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
375 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
376 needs 2 args which is not valid in ErrorLog manual)
377 trawick: nit: fix "writing" in "/* NULL if we are writing to syslog */"
378 (sorry, haven't finished reviewing completely)
379 jim: What is the status of this??
381 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
382 and ProxyMatch section to distinguish between normal workers and workers
383 with regex substitutions in the name. Implement handling of such workers
384 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
385 matched and used for request. PR 43513.
386 trunk patch: http://svn.apache.org/r1609680
387 http://svn.apache.org/r1609688
388 http://svn.apache.org/r1641381
389 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
390 Also added missing r1609688 to the patchset.
391 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
393 -0: covener tried to review this one in Austin with Jeff. Does the added match function
394 really cover a very narrow set of parameters with the way it skips over backreferences?
395 Also, why a new API vs. just setting the field inline?
397 * mod_systemd: New module, for integration with systemd on Linux.

406 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
408 sf comments: The IdleShutdown logic seems broken. Consider a single
409 active connection that is stalled for 10 seconds. That
410 connection will be broken after GracefulShutdownTimeout.
411 A better logic would be to check if there is any open
412 connection that is not in keep-alive state.
414 * mod_journald: Add new module mod_journald to log error logs into journald.
415 This patch needs changes done in mod_systemd patch (already

440 2.4.x patch: trunk patch works modulo CHANGES
442 -1: rpluem: This change is still disputed. See
443 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
445 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
446 compiled by the build compiler instead of the host compiler.
447 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

452 fuankg: on hold until we agree for a better and more simple solution ...
454 * Makefile.win: Added copying of .vbs / .wsf CGIs to Windows install target.
455 Moved fixing of shebang to separate target so that it is
456 no longer executed by default and all CGIs remain inactive.

460 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
463 This commit is essentially deciding that an httpd install on
464 Windows now has printenv/testcgi written in 2 more languages.
465 To the extent that the usefulness is that it shows how to make scripts
466 of these types executable by httpd, I believe that the documentation
467 is the proper place to solve that. To the extent that the usefullness
468 is to show how to implement a CGI in these particular languages, I believe
469 that the httpd distribution and documentation in general is not the
470 place for that. Historically these types of scripts have caused problems
471 for downstream vendorsas well as newbies (and sometimes the intersection
472 of those two groups) who don't understand that these are information leaks
473 once they are enabled, and the subtlety of the way they are disabled ("Apache
474 messed up the first line; let me fix that") contributes to that.
475 fuankg notes: I've just added a big warning to all CGI scripts which should now
476 make absolutely clear that these CGIs are for testing purpose only - so those
477 who enable those scripts with inserting the right shebang should be 100% aware
478 of any risks (this should cover your last point).
479 jim: trawick, does the above address your concerns?
480 trawick: to some extent (somebody reading the script gets an idea)
481 Why isn't the configuration requirement documented instead
482 of described indirectly in a sample?
483 Why are these new samples added to the install without three
484 votes? (I didn't veto it; put your name next to the two
485 existing ones and I'll be satisfied that enough people
486 considered this addition as an appropriate solution for a
487 real httpd usability problem.)
488 wrowe: I'd agree with trawick, and suggest that these scripts can begin
489 their life somewhere in the manual/ tree. This really seems like
490 the place where /usr/share/httpd/examples/ would be useful, but
491 there isn't an ordinary directory for that. Since we want none
492 of the scripts to function 'out of the box', what about a new
493 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
496 * core: block Define and Undefine in vhost and directory context. Because
497 it is EXEC_ON_READ, it "breaks out" of these contexts anyway.

500 2.4.x patch: http://people.apache.org/~covener/patches/2.4.x-define-limits.diff
501 +1: covener (I need to review the docs manually in this area)
502 -1: wrowe (blocking will break "working" .conf files on a subversion update
503 meant to pick up security fixes. "Alerting" I would agree to.)
