81 Contributors looking for a mission:
83 * Just do an egrep on "TODO" or "XXX" in the source.
85 * Review the bug database at: http://issues.apache.org/bugzilla/
87 * Review the "PatchAvailable" bugs in the bug database:
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

136 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
138 ylavic: Changed to v5 (+r1812193) which hopefully should address compat
140 icing: builds and runs fine in my tests. However I do not have <Proxy> specific
141 setups to check that all config commands apply properly. Otherwise, looks
142 backward compatible to me.
143 ylavic: Argh, update to v6 since v5 partially reverted r1747069 (which was
144 a later change than the original proposal). Here is v5 vs v6 diff:
145 http://home.apache.org/~ylavic/patches/httpd-2.4.x-r1740928_and_co-v5_vs_v6.diff
146 Not really related to the functionality of this proposal, so I
147 didn't reset Stefan's vote...

166 2.4 convenience patch (includes CHANGES):
167 http://home.apache.org/~jim/patches/RemoteIPProxyProtocol.2.4-v2.patch
168 http://svn.apache.org/r1818279
170 ylavic: RemoteIPProxyProtocol* are documented as scoped to server config
171 and virtual host, though using ap_server_conf makes them global
172 only (thus less useful too...).
174 *) core/mod_ssl: Add new flag int to module struct. Define first bit for keeping
175 server config records non-shared instances, set for mod_ssl to make manipulations
177 trunk patch: svn merge -c 1809302,1809303,1809305,1809311,1809314,1809713 ^/httpd/httpd/trunk .
178 2.4.x patch: https://svn.apache.org/repos/asf/httpd/httpd/patches/2.4.x/backport-module-flags.diff
179 (merge with alterations for mmn etc., updated after review by Yann)
181 niq: Can someone post a pointer to discussion of this on dev list?
182 In particular the API change and apparent #ifdef ABI?
184 *) mod_md: backport of ACME (Let's Encrypt) support. Needs mod_ssl backport proposal beneath to
185 not only compile but do something.

226 ylavic: joint proposal because the second change depends on the
227 ap_update_child_status() added by the first one. Hopefully the
228 first change is simple enough, the second one is quite straight
232 PATCHES/ISSUES THAT ARE BEING WORKED
233 [ New entries should be added at the START of the list ]
235 *) mod_ssl: Return 502 instead of 500 when SSL peer check or
236 proxy_post_handshake hook fails.
237 Trunk patch: r1645529 (works)
238 2.4.x patch which adds CHANGES: https://emptyhammock.com/media/downloads/r1645529-to-2.4.x.txt
240 ylavic: there may be missing bits, see thread for commit r1736510.
242 *) core: Drop an invalid Last-Modified header value coming
243 from a (F)CGI script instead of replacing it with Unix epoch.
244 Warn the users about Last-Modified header value replacements
245 and violations of the RFC.
246 trunk patch: http://svn.apache.org/r1748379
247 http://svn.apache.org/r1750747

254 2.4.x: trunk patches work, final view:
255 http://home.apache.org/~elukey/httpd-2.4.x-core-last_modified_tz_logging.patch
256 The problem has been discussed in dev@ extensively but we did not reach a common
257 agreement about how to proceed in the long term. While we wait, I would really like
258 to introduce useful logs for the users (the starting point of this change was a users@
259 email thread). If this is not the right way to go I will move the patch to other
260 sections of STATUS (stalled or being worked).
261 The code has been tested with a simple PHP script returning different Last-Modified
262 headers (GMT now, GMT now Europe/Paris, GMT tomorrow, GMT yesterday, PST now).
265 *) http: Don't remove the Content-Length of zero from a HEAD response if
266 it comes from an origin server, module or script. Allow the previous
267 behaviour (for legacy/buggy modules only, not origin) by also backporting
268 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
269 comes for free with the same commit).
270 trunk patch: http://svn.apache.org/r1554303
271 http://svn.apache.org/r1678215
272 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
274 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
275 ints added at the end of core_server_config, the proposed merge
276 does a minor bump only.
277 minfrin: Two new directives need to be documented.
279 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
280 fetching the request body, so to minimize the delay between it is supposed
281 to be alive and the first bytes sent: this is a best effort to prevent the
282 backend from closing because of idle or keepalive timeout in the meantime.
283 Also, handle a new "proxy-flushall" environment variable which allows to
284 flush any forwarded body data immediately. PR 56541+37920.
285 trunk patch: http://svn.apache.org/r1656259
286 http://svn.apache.org/r1656359 (CHANGES entry)
287 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
289 -0: jim: This seems to be a hit to normal performance, to handle an
290 error and/or non-normal condition. The pre-fetch is
291 expensive, and is always done, even before we know that
292 the backend is available to rec' it. I understand the
293 error described, but is the fix actually worth it (plus
294 it seems to allow for a DDoS vector).
295 ylavic: It seems to me that the problem is real since we reuse the
296 connection before prefetching 16K (either controlled by the
297 client, or by an input filter), we currently always prefetch
298 these bytes already. Regarding performance I don't see any
299 difference (more cycles) compared with the current code.
300 However I think I failed to rebuild the header_brigade when
301 the proxy loop is retried (ping), so I need to rework this.
302 Do you think we'd better remove the prefetch, or maybe just
303 make it nonblocking (by default)?
304 jim: Non-blocking seems the best way to handle...
306 * mod_dav: Allow other modules to become providers and add ACLs
307 to the DAV response. Requires a release of apr-util v1.6.
308 trunk patch: http://svn.apache.org/r1748322
309 2.4.x: trunk works modulo CHANGES/MMN
311 rpluem asks: Will this compile with apr-util < v1.6 and keep
312 mod_dav working (without the new features of the patch of course)?
313 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
314 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
315 minfrin: Yes, as you can see in the patch everything applies only
316 if APR_XML_X2T_PARSED is defined, and the patch was tested with
317 both apr-util v1.6 and apr-util v1.5.
318 -1: jorton, breaks binary backwards compat per dev@ discuss
319 msgid <20160902120654.GA12674@redhat.com>
320 (& also, making the structure change with apr-util version
321 means it breaks binary compat across an apr-util upgrade?)
323 * Support PCRE2 (10.x) in place of PCRE (8.x).
324 Submitted by: wrowe, Petr Pisar [ppisar redhat.com]

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

364 trawick: nit: fix "writing" in "/* NULL if we are writing to syslog */"
365 (sorry, haven't finished reviewing completely)
366 jim: What is the status of this??
368 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
369 and ProxyMatch section to distinguish between normal workers and workers
370 with regex substitutions in the name. Implement handling of such workers
371 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
372 matched and used for request. PR 43513.

381 really cover a very narrow set of parameters with the way it skips over backreferences?
382 Also, why a new API vs. just setting the field inline?
384 * core: Add support for systemd socket activation.

391 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
394 * mod_proxy: Ensure network errors detected by the proxy are returned as
395 504 Gateway Timeout as opposed to 502 Bad Gateway
396 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
397 2.4.x patch: trunk patch works modulo CHANGES
399 -1: rpluem: This change is still disputed. See
400 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
402 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
403 compiled by the build compiler instead of the host compiler.
404 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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

457 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
458 http://svn.apache.org/r1812339
460 jchampion: Looks like the headers require GCC extensions to compile, so
461 mod_journald can't be configured in maintainer mode (-std=c89).
462 Can anyone else reproduce, or is it just my distro?
463 ylavic: missing r1812339 for maintainer-mode/c89/-Werror compliance,
464 needed if the above configure.in proposal gets backported.
465 Note that r1812339 could be backported in any case, even if
466 the above configure.in proposal does not get accepted.
468 * mod_systemd: New module, for integration with systemd on Linux.

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