96 CURRENT RELEASE NOTES:
98 * Forward binary compatibility is expected of Apache 2.4.x releases, such
99 that no MMN major number changes will occur after 2.4.1. Such changes can
100 only be made in the trunk.
102 * All commits to branches/2.4.x must be reflected in SVN trunk,
103 as well, if they apply. Logical progression is commit to trunk
104 then merge into branches/2.4.x, as applicable.
106 * Current exceptions for RTC for this branch:
111 . non-Unix, single-platform code
113 RELEASE SHOWSTOPPERS:
116 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:

119 *) mod_ssl: reset client-verify state of connection when renegotiation is
121 trunk patch: http://svn.apache.org/r1750779
122 2.4.x: trunk patch works
123 +1: icing, jim, ylavic
126 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
127 [ New proposals should be added at the end of the list ]
129 *) mod_ssl: Return 502 instead of 500 when SSL peer check or
130 proxy_post_handshake hook fails.
131 Trunk patch: r1645529 (works)
132 2.4.x patch which adds CHANGES: https://emptyhammock.com/media/downloads/r1645529-to-2.4.x.txt
134 ylavic: there may be missing bits, see thread for commit r1736510.
136 *) mod_dav: Add support for childtags to dav_error.
137 trunk patch: http://svn.apache.org/r1746207
138 2.4.x: trunk works modulo CHANGES/MMN
141 *) mod_dav: Add dav_begin_multistatus, dav_send_one_response,
142 dav_finish_multistatus, dav_send_multistatus, dav_handle_err,
143 dav_failed_proppatch, dav_success_proppatch to mod_dav.h.
144 trunk patch: http://svn.apache.org/r1748047
145 2.4.x: trunk works modulo CHANGES/MMN
148 *) core: Drop an invalid Last-Modified header value coming
149 from a FCGI/CGI script instead of replacing it with Unix epoch.
150 trunk patch: http://svn.apache.org/r1748379
151 2.4.x: trunk patch works
155 PATCHES/ISSUES THAT ARE BEING WORKED
157 *) http: Don't remove the Content-Length of zero from a HEAD response if
158 it comes from an origin server, module or script. Allow the previous
159 behaviour (for legacy/buggy modules only, not origin) by also backporting
160 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
161 comes for free with the same commit).
162 trunk patch: http://svn.apache.org/r1554303
163 http://svn.apache.org/r1678215
164 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
166 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
167 ints added at the end of core_server_config, the proposed merge
168 does a minor bump only.
169 minfrin: Two new directives need to be documented.
171 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
172 fetching the request body, so to minimize the delay between it is supposed
173 to be alive and the first bytes sent: this is a best effort to prevent the
174 backend from closing because of idle or keepalive timeout in the meantime.
175 Also, handle a new "proxy-flushall" environment variable which allows to
176 flush any forwarded body data immediately. PR 56541+37920.
177 trunk patch: http://svn.apache.org/r1656259
178 http://svn.apache.org/r1656359 (CHANGES entry)
179 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
181 -0: jim: This seems to be a hit to normal performance, to handle an
182 error and/or non-normal condition. The pre-fetch is
183 expensive, and is always done, even before we know that
184 the backend is available to rec' it. I understand the
185 error described, but is the fix actually worth it (plus
186 it seems to allow for a DDoS vector).
187 ylavic: It seems to me that the problem is real since we reuse the
188 connection before prefetching 16K (either controlled by the
189 client, or by an input filter), we currently always prefetch
190 these bytes already. Regarding performance I don't see any
191 difference (more cycles) compared with the current code.
192 However I think I failed to rebuild the header_brigade when
193 the proxy loop is retried (ping), so I need to rework this.
194 Do you think we'd better remove the prefetch, or maybe just
195 make it nonblocking (by default)?
196 jim: Non-blocking seems the best way to handle...
198 * mod_dav: Allow other modules to become providers and add ACLs
199 to the DAV response. Requires a release of apr-util v1.6.
200 trunk patch: http://svn.apache.org/r1748322
201 2.4.x: trunk works modulo CHANGES/MMN
203 rpluem asks: Will this compile with apr-util < v1.6 and keep
204 mod_dav working (without the new features of the patch of course)?
205 I doubt that we will require apr-util 1.6 for the lifetime of 2.4.x
206 (see the discussion around ap_cstr_casecmp[n] an apr 1.6)
207 minfrin: Yes, as you can see in the patch everything applies only
208 if APR_XML_X2T_PARSED is defined, and the patch was tested with
209 both apr-util v1.6 and apr-util v1.5.
211 PATCHES/ISSUES THAT ARE STALLED
213 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
214 backport keeps syslog logging as part of httpd core and only adds
215 API to allow other modules to be used for error logging.
216 trunk patch: http://svn.apache.org/r1525597
217 http://svn.apache.org/r1525664
218 http://svn.apache.org/r1525845
219 http://svn.apache.org/r1527003

225 http://svn.apache.org/r1544156
226 http://svn.apache.org/r1626978
227 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
229 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
230 needs 2 args which is not valid in ErrorLog manual)
231 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
232 (sorry, haven't finished reviewing completely)
233 jim: What is the status of this??
235 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
236 and ProxyMatch section to distinguish between normal workers and workers
237 with regex substitutions in the name. Implement handling of such workers
238 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
239 matched and used for request. PR 43513.
240 trunk patch: http://svn.apache.org/r1609680
241 http://svn.apache.org/r1609688
242 http://svn.apache.org/r1641381
243 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
244 Also added missing r1609688 to the patchset.
245 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
247 -0: covener tried to review this one in Austin with Jeff. Does the added match function
248 really cover a very narrow set of parameters with the way it skips over backreferences?
249 Also, why a new API vs. just setting the field inline?
251 * mod_systemd: New module, for integration with systemd on Linux.
252 trunk patch: http://svn.apache.org/r1393976

260 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
262 sf comments: The IdleShutdown logic seems broken. Consider a single
263 active connection that is stalled for 10 seconds. That
264 connection will be broken after GracefulShutdownTimeout.
265 A better logic would be to check if there is any open
266 connection that is not in keep-alive state.
268 * mod_journald: Add new module mod_journald to log error logs into journald.
269 This patch needs changes done in mod_systemd patch (already
271 trunk patch: http://svn.apache.org/r1610339
272 http://svn.apache.org/r1621806
273 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
275 rjung, minfrin: Not understanding "This patch needs changes done in
276 mod_systemd patch", am I right in understanding this patch is
278 jkaluza: No, that patch is not committed yet. It is in STALLED section.
279 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
281 * core: Add support for systemd socket activation.

291 * mod_proxy: Ensure network errors detected by the proxy are returned as
292 504 Gateway Timout as opposed to 502 Bad Gateway
293 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
294 2.4.x patch: trunk patch works modulo CHANGES
296 -1: rpluem: This change is still disputed. See
297 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
299 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
300 compiled by the build compiler instead of the host compiler.
301 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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

353 http://svn.apache.org/r1656122
354 2.4.x patch: http://people.apache.org/~covener/patches/2.4.x-define-limits.diff
355 +1: covener (I need to review the docs manually in this area)
356 -1: wrowe (blocking will break "working" .conf files on a subversion update
357 meant to pick up security fixes. "Alerting" I would agree to.)
