82 Contributors looking for a mission:
84 * Just do an egrep on "TODO" or "XXX" in the source.
86 * Review the bug database at: http://issues.apache.org/bugzilla/
88 * Review the "PatchAvailable" bugs in the bug database:
90 https://issues.apache.org/bugzilla/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&product=Apache+httpd-2&keywords=PatchAvailable
92 After testing, you can append a comment saying "Reviewed and tested".
94 * Open bugs in the bug database.
96 * See also the STATUS file in the docs/ directory, which lists documentation-specific TODO items.
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

141 2.4.x patch which adds CHANGES: https://emptyhammock.com/media/downloads/r1645529-to-2.4.x.txt
143 ylavic: there may be missing bits, see thread for commit r1736510.
145 *) core: Drop an invalid Last-Modified header value coming
146 from a (F)CGI script instead of replacing it with Unix epoch.
147 Warn the users about Last-Modified header value replacements
148 and violations of the RFC.
149 trunk patch: http://svn.apache.org/r1748379
150 http://svn.apache.org/r1750747

157 2.4.x: trunk patches work, final view:
158 http://home.apache.org/~elukey/httpd-2.4.x-core-last_modified_tz_logging.patch
159 The problem has been discussed in dev@ extensively but we did not reach a common
160 agreement about how to proceed in the long term. While we wait, I would really like
161 to introduce useful logs for the users (the starting point of this change was a users@
162 email thread). If this is not the right way to go I will move the patch to other
163 sections of STATUS (stalled or being worked).
164 The code has been tested with a simple PHP script returning different Last-Modified
165 headers (GMT now, GMT now Europe/Paris, GMT tomorrow, GMT yesterday, PST now).
168 *) http: Don't remove the Content-Length of zero from a HEAD response if
169 it comes from an origin server, module or script. Allow the previous
170 behaviour (for legacy/buggy modules only, not origin) by also backporting
171 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
172 comes for free with the same commit).
173 trunk patch: http://svn.apache.org/r1554303
174 http://svn.apache.org/r1678215
175 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
177 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
178 ints added at the end of core_server_config, the proposed merge
179 does a minor bump only.
180 minfrin: Two new directives need to be documented.
182 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
183 fetching the request body, so to minimize the delay between it is supposed
184 to be alive and the first bytes sent: this is a best effort to prevent the
185 backend from closing because of idle or keepalive timeout in the meantime.
186 Also, handle a new "proxy-flushall" environment variable which allows to
187 flush any forwarded body data immediately. PR 56541+37920.
188 trunk patch: http://svn.apache.org/r1656259
189 http://svn.apache.org/r1656359 (CHANGES entry)
190 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
192 -0: jim: This seems to be a hit to normal performance, to handle an
193 error and/or non-normal condition. The pre-fetch is
194 expensive, and is always done, even before we know that
195 the backend is available to rec' it. I understand the
196 error described, but is the fix actually worth it (plus
197 it seems to allow for a DDoS vector).
198 ylavic: It seems to me that the problem is real since we reuse the
199 connection before prefetching 16K (either controlled by the
200 client, or by an input filter), we currently always prefetch
201 these bytes already. Regarding performance I don't see any
202 difference (more cycles) compared with the current code.
203 However I think I failed to rebuild the header_brigade when
204 the proxy loop is retried (ping), so I need to rework this.
205 Do you think we'd better remove the prefetch, or maybe just
206 make it nonblocking (by default)?
207 jim: Non-blocking seems the best way to handle...
209 * Support PCRE2 (10.x) in place of PCRE (8.x).

216 http://svn.apache.org/r1773870
217 http://svn.apache.org/r1773882
218 wrowe notes that the current code is too inefficient, owing to the fact
219 that the ovector is a required allocation and is no longer allocated on
220 the stack, by design. The correct fix is an apr userdata allocation on
221 the appropriate pool, which would be thread-safe, but the actual API of
222 ap_regexec[_len]() offers us no pool. We cannot associate that pool with
223 the ap_regex_t, because a single regex may be used by many threads in
224 parallel and is not thread-safe beyond initialization.
225 So the only fix allowing us to use PCRE 10 in httpd 2.4 would be to write
226 this as a thread safe storage buffer for the majority of cases (<10 $args)
227 and we don't have a portable tls mechanism to do so.
228 jorton: Adding ap_pregexec/_len which pass a pool would also work
229 for internal users of this api; not sure if performance
230 impact is significant from using malloc here.
233 PATCHES/ISSUES THAT ARE STALLED
235 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
236 backport keeps syslog logging as part of httpd core and only adds
237 API to allow other modules to be used for error logging.
238 trunk patch: http://svn.apache.org/r1525597
239 http://svn.apache.org/r1525664

248 http://svn.apache.org/r1626978
249 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
251 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
252 needs 2 args which is not valid in ErrorLog manual)
253 trawick: nit: fix "writing" in "/* NULL if we are writing to syslog */"
254 (sorry, haven't finished reviewing completely)
255 jim: What is the status of this??
257 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
258 and ProxyMatch section to distinguish between normal workers and workers
259 with regex substitutions in the name. Implement handling of such workers
260 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
261 matched and used for request. PR 43513.
262 trunk patch: http://svn.apache.org/r1609680
263 http://svn.apache.org/r1609688
264 http://svn.apache.org/r1641381
265 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
266 Also added missing r1609688 to the patchset.
267 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
269 -0: covener tried to review this one in Austin with Jeff. Does the added match function
270 really cover a very narrow set of parameters with the way it skips over backreferences?
271 Also, why a new API vs. just setting the field inline?
273 * core: Add support for systemd socket activation.

280 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-socket-activation.patch
283 * mod_proxy: Ensure network errors detected by the proxy are returned as
284 504 Gateway Timeout as opposed to 502 Bad Gateway
285 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
286 2.4.x patch: trunk patch works modulo CHANGES
288 -1: rpluem: This change is still disputed. See

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

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

306 2.4.x patch: http://people.apache.org/~fuankg/diffs/httpd-2.4.x-Makefile.win.diff
309 This commit is essentially deciding that an httpd install on
310 Windows now has printenv/testcgi written in 2 more languages.
311 To the extent that the usefulness is that it shows how to make scripts
312 of these types executable by httpd, I believe that the documentation
313 is the proper place to solve that. To the extent that the usefullness
314 is to show how to implement a CGI in these particular languages, I believe
315 that the httpd distribution and documentation in general is not the
316 place for that. Historically these types of scripts have caused problems
317 for downstream vendorsas well as newbies (and sometimes the intersection
318 of those two groups) who don't understand that these are information leaks
319 once they are enabled, and the subtlety of the way they are disabled ("Apache
320 messed up the first line; let me fix that") contributes to that.
321 fuankg notes: I've just added a big warning to all CGI scripts which should now
322 make absolutely clear that these CGIs are for testing purpose only - so those
323 who enable those scripts with inserting the right shebang should be 100% aware
324 of any risks (this should cover your last point).
325 jim: trawick, does the above address your concerns?
326 trawick: to some extent (somebody reading the script gets an idea)
327 Why isn't the configuration requirement documented instead
328 of described indirectly in a sample?
329 Why are these new samples added to the install without three
330 votes? (I didn't veto it; put your name next to the two
331 existing ones and I'll be satisfied that enough people
332 considered this addition as an appropriate solution for a
333 real httpd usability problem.)
334 wrowe: I'd agree with trawick, and suggest that these scripts can begin
335 their life somewhere in the manual/ tree. This really seems like
336 the place where /usr/share/httpd/examples/ would be useful, but
337 there isn't an ordinary directory for that. Since we want none
338 of the scripts to function 'out of the box', what about a new
339 cgi-examples/ dir alongside cgi-bin/? Otherwise manual/cgi/examples
342 *) mod_journald: Add new module mod_journald to log error logs into journald.

346 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
347 http://svn.apache.org/r1812339
349 jchampion: Looks like the headers require GCC extensions to compile, so
350 mod_journald can't be configured in maintainer mode (-std=c89).
351 Can anyone else reproduce, or is it just my distro?
352 ylavic: missing r1812339 for maintainer-mode/c89/-Werror compliance,
353 needed if the above configure.in proposal gets backported.
354 Note that r1812339 could be backported in any case, even if
355 the above configure.in proposal does not get accepted.
357 * mod_systemd: New module, for integration with systemd on Linux.

366 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
368 sf comments: The IdleShutdown logic seems broken. Consider a single
369 active connection that is stalled for 10 seconds. That
370 connection will be broken after GracefulShutdownTimeout.
371 A better logic would be to check if there is any open
372 connection that is not in keep-alive state.
