89 https://issues.apache.org/bugzilla/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&product=Apache+httpd-2&keywords=PatchAvailable
91 After testing, you can append a comment saying "Reviewed and tested".
93 * Open bugs in the bug database.
95 * See also the STATUS file in the docs/ directory, which lists documentation-specific TODO items.
98 CURRENT RELEASE NOTES:
100 * Forward binary compatibility is expected of Apache 2.4.x releases, such
101 that no MMN major number changes will occur after 2.4.1. Such changes can
102 only be made in the trunk.
104 * All commits to branches/2.4.x must be reflected in SVN trunk,
105 as well, if they apply. Logical progression is commit to trunk
106 then merge into branches/2.4.x, as applicable.
108 * Current exceptions for RTC for this branch:
113 . non-Unix, single-platform code
115 RELEASE SHOWSTOPPERS:
118 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:

131 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
132 [ New proposals should be added at the end of the list ]
134 *) mod_proxy, mod_ssl: Handle SSLProxy* directives in <Proxy> sections,
135 allowing per backend TLS configuration.
136 trunk patch: http://svn.apache.org/r1740928
137 http://svn.apache.org/r1740960
138 http://svn.apache.org/r1740967

143 http://svn.apache.org/r1781313
144 http://svn.apache.org/r1812193
145 2.4.x patch: https://svn.apache.org/repos/asf/httpd/httpd/patches/2.4.x/httpd-2.4.x-r1740928_and_co-v6.patch
147 ylavic: Changed to v5 (+r1812193) which hopefully should address compat
149 icing: builds and runs fine in my tests. However I do not have <Proxy> specific
150 setups to check that all config commands apply properly. Otherwise, looks
151 backward compatible to me.
152 ylavic: Argh, update to v6 since v5 partially reverted r1747069 (which was
153 a later change than the original proposal). Here is v5 vs v6 diff:
154 http://home.apache.org/~ylavic/patches/httpd-2.4.x-r1740928_and_co-v5_vs_v6.diff
155 Not really related to the functionality of this proposal, so I
156 didn't reset Stefan's vote...
158 *) mod_remoteip: Add PROXY protocol support
159 trunk patch: http://svn.apache.org/r1776575

174 http://svn.apache.org/r1818279
175 2.4 convenience patch (includes CHANGES):
176 http://home.apache.org/~jim/patches/RemoteIPProxyProtocol.2.4-v2.patch
177 http://svn.apache.org/r1818279
179 ylavic: RemoteIPProxyProtocol* are documented as scoped to server config
180 and virtual host, though using ap_server_conf makes them global
181 only (thus less useful too...).
183 *) mod_proxy_uwsgi: Add in UWSGI proxy (sub)module
184 trunk patch: http://svn.apache.org/r1810358
185 http://svn.apache.org/r1810362

193 2.4.x patch: trunk works (modulo CHANGES)

199 PATCHES/ISSUES THAT ARE BEING WORKED
200 [ New entries should be added at the START of the list ]
202 *) mod_ssl: Return 502 instead of 500 when SSL peer check or
203 proxy_post_handshake hook fails.
204 Trunk patch: r1645529 (works)
205 2.4.x patch which adds CHANGES: https://emptyhammock.com/media/downloads/r1645529-to-2.4.x.txt
207 ylavic: there may be missing bits, see thread for commit r1736510.
209 *) core: Drop an invalid Last-Modified header value coming
210 from a (F)CGI script instead of replacing it with Unix epoch.
211 Warn the users about Last-Modified header value replacements
212 and violations of the RFC.
213 trunk patch: http://svn.apache.org/r1748379
214 http://svn.apache.org/r1750747
215 http://svn.apache.org/r1750749
216 http://svn.apache.org/r1750953
217 http://svn.apache.org/r1751138
218 http://svn.apache.org/r1751139
219 http://svn.apache.org/r1751147
220 http://svn.apache.org/r1757818
221 2.4.x: trunk patches work, final view:
222 http://home.apache.org/~elukey/httpd-2.4.x-core-last_modified_tz_logging.patch
223 The problem has been discussed in dev@ extensively but we did not reach a common
224 agreement about how to proceed in the long term. While we wait, I would really like
225 to introduce useful logs for the users (the starting point of this change was a users@
226 email thread). If this is not the right way to go I will move the patch to other
227 sections of STATUS (stalled or being worked).
228 The code has been tested with a simple PHP script returning different Last-Modified
229 headers (GMT now, GMT now Europe/Paris, GMT tomorrow, GMT yesterday, PST now).
232 *) http: Don't remove the Content-Length of zero from a HEAD response if
233 it comes from an origin server, module or script. Allow the previous
234 behaviour (for legacy/buggy modules only, not origin) by also backporting
235 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
236 comes for free with the same commit).
237 trunk patch: http://svn.apache.org/r1554303
238 http://svn.apache.org/r1678215
239 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
241 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
242 ints added at the end of core_server_config, the proposed merge
243 does a minor bump only.
244 minfrin: Two new directives need to be documented.
246 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
247 fetching the request body, so to minimize the delay between it is supposed
248 to be alive and the first bytes sent: this is a best effort to prevent the
249 backend from closing because of idle or keepalive timeout in the meantime.
250 Also, handle a new "proxy-flushall" environment variable which allows to
251 flush any forwarded body data immediately. PR 56541+37920.
252 trunk patch: http://svn.apache.org/r1656259
253 http://svn.apache.org/r1656359 (CHANGES entry)
254 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
256 -0: jim: This seems to be a hit to normal performance, to handle an
257 error and/or non-normal condition. The pre-fetch is
258 expensive, and is always done, even before we know that
259 the backend is available to rec' it. I understand the
260 error described, but is the fix actually worth it (plus
261 it seems to allow for a DDoS vector).
262 ylavic: It seems to me that the problem is real since we reuse the
263 connection before prefetching 16K (either controlled by the
264 client, or by an input filter), we currently always prefetch
265 these bytes already. Regarding performance I don't see any
266 difference (more cycles) compared with the current code.
267 However I think I failed to rebuild the header_brigade when
268 the proxy loop is retried (ping), so I need to rework this.
269 Do you think we'd better remove the prefetch, or maybe just
270 make it nonblocking (by default)?
271 jim: Non-blocking seems the best way to handle...
273 * mod_dav: Allow other modules to become providers and add ACLs
274 to the DAV response. Requires a release of apr-util v1.6.
275 trunk patch: http://svn.apache.org/r1748322
276 2.4.x: trunk works modulo CHANGES/MMN
278 rpluem asks: Will this compile with apr-util < v1.6 and keep
279 mod_dav working (without the new features of the patch of course)?
280 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
281 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
282 minfrin: Yes, as you can see in the patch everything applies only
283 if APR_XML_X2T_PARSED is defined, and the patch was tested with
284 both apr-util v1.6 and apr-util v1.5.
285 -1: jorton, breaks binary backwards compat per dev@ discuss
286 msgid <20160902120654.GA12674@redhat.com>
287 (& also, making the structure change with apr-util version
288 means it breaks binary compat across an apr-util upgrade?)
290 * Support PCRE2 (10.x) in place of PCRE (8.x).
291 Submitted by: wrowe, Petr Pisar [ppisar redhat.com]
293 http://svn.apache.org/r1773454
294 http://svn.apache.org/r1773741
295 http://svn.apache.org/r1773742

297 http://svn.apache.org/r1773870
298 http://svn.apache.org/r1773882
299 wrowe notes that the current code is too inefficient, owing to the fact
300 that the ovector is a required allocation and is no longer allocated on
301 the stack, by design. The correct fix is an apr userdata allocation on
302 the appropriate pool, which would be thread-safe, but the actual API of
303 ap_regexec[_len]() offers us no pool. We cannot associate that pool with
304 the ap_regex_t, because a single regex may be used by many threads in
305 parallel and is not thread-safe beyond initialization.
306 So the only fix allowing us to use PCRE 10 in httpd 2.4 would be to write
307 this as a thread safe storage buffer for the majority of cases (<10 $args)
308 and we don't have a portable tls mechanism to do so.
311 PATCHES/ISSUES THAT ARE STALLED
313 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
314 backport keeps syslog logging as part of httpd core and only adds
315 API to allow other modules to be used for error logging.
316 trunk patch: http://svn.apache.org/r1525597
317 http://svn.apache.org/r1525664

327 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
329 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
330 needs 2 args which is not valid in ErrorLog manual)
331 trawick: nit: fix "writing" in "/* NULL if we are writing to syslog */"
332 (sorry, haven't finished reviewing completely)
333 jim: What is the status of this??
335 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
336 and ProxyMatch section to distinguish between normal workers and workers
337 with regex substitutions in the name. Implement handling of such workers
338 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
339 matched and used for request. PR 43513.
340 trunk patch: http://svn.apache.org/r1609680
341 http://svn.apache.org/r1609688
342 http://svn.apache.org/r1641381
343 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
344 Also added missing r1609688 to the patchset.
345 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
347 -0: covener tried to review this one in Austin with Jeff. Does the added match function
348 really cover a very narrow set of parameters with the way it skips over backreferences?
349 Also, why a new API vs. just setting the field inline?
351 * core: Add support for systemd socket activation.

358 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
361 * mod_proxy: Ensure network errors detected by the proxy are returned as
362 504 Gateway Timeout as opposed to 502 Bad Gateway
363 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
364 2.4.x patch: trunk patch works modulo CHANGES
366 -1: rpluem: This change is still disputed. See

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

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

384 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
387 This commit is essentially deciding that an httpd install on
388 Windows now has printenv/testcgi written in 2 more languages.
389 To the extent that the usefulness is that it shows how to make scripts
390 of these types executable by httpd, I believe that the documentation
391 is the proper place to solve that. To the extent that the usefullness
392 is to show how to implement a CGI in these particular languages, I believe
393 that the httpd distribution and documentation in general is not the
394 place for that. Historically these types of scripts have caused problems
395 for downstream vendorsas well as newbies (and sometimes the intersection
396 of those two groups) who don't understand that these are information leaks
397 once they are enabled, and the subtlety of the way they are disabled ("Apache
398 messed up the first line; let me fix that") contributes to that.
399 fuankg notes: I've just added a big warning to all CGI scripts which should now
400 make absolutely clear that these CGIs are for testing purpose only - so those
401 who enable those scripts with inserting the right shebang should be 100% aware
402 of any risks (this should cover your last point).
403 jim: trawick, does the above address your concerns?
404 trawick: to some extent (somebody reading the script gets an idea)
405 Why isn't the configuration requirement documented instead
406 of described indirectly in a sample?
407 Why are these new samples added to the install without three
408 votes? (I didn't veto it; put your name next to the two
409 existing ones and I'll be satisfied that enough people
410 considered this addition as an appropriate solution for a
411 real httpd usability problem.)
412 wrowe: I'd agree with trawick, and suggest that these scripts can begin
413 their life somewhere in the manual/ tree. This really seems like
414 the place where /usr/share/httpd/examples/ would be useful, but
415 there isn't an ordinary directory for that. Since we want none
416 of the scripts to function 'out of the box', what about a new
417 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
420 *) mod_journald: Add new module mod_journald to log error logs into journald.

425 http://svn.apache.org/r1812339
427 jchampion: Looks like the headers require GCC extensions to compile, so
428 mod_journald can't be configured in maintainer mode (-std=c89).
429 Can anyone else reproduce, or is it just my distro?
430 ylavic: missing r1812339 for maintainer-mode/c89/-Werror compliance,
431 needed if the above configure.in proposal gets backported.
432 Note that r1812339 could be backported in any case, even if
433 the above configure.in proposal does not get accepted.
435 * mod_systemd: New module, for integration with systemd on Linux.

446 sf comments: The IdleShutdown logic seems broken. Consider a single
447 active connection that is stalled for 10 seconds. That
448 connection will be broken after GracefulShutdownTimeout.
449 A better logic would be to check if there is any open
450 connection that is not in keep-alive state.
