93 CURRENT RELEASE NOTES:
95 * Forward binary compatibility is expected of Apache 2.4.x releases, such
96 that no MMN major number changes will occur after 2.4.1. Such changes can
97 only be made in the trunk.
99 * All commits to branches/2.4.x must be reflected in SVN trunk,
100 as well, if they apply. Logical progression is commit to trunk
101 then merge into branches/2.4.x, as applicable.
103 * Current exceptions for RTC for this branch:
108 . non-Unix, single-platform code
110 RELEASE SHOWSTOPPERS:
113 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
114 [ start all new proposals below, under PATCHES PROPOSED. ]
117 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
118 [ New proposals should be added at the end of the list ]
120 *) mod_proxy_hcheck: Dynamic reverse proxy backend health check module
121 Trunk version of patch: <various>
122 Backport version for 2.4.x of patch:
123 http://home.apache.org/~jim/patches/hcheck-2.4-v2.patch
126 ylavic: Looks like the changes on struct proxy_worker_shared would break
127 startup with "BalancerPersist on" due to the strict checks on
128 the sizes of existing slotmems (slotmem_create/attach)?
129 jim: Yes, that is right (re: breakage)... this would be noted at
131 ylavic: OK, this is just that persisted slotmems won't be reused on first
132 startup, not that the startup will fail (as I first thought).
134 *) core/util_script: relax alphanumeric filter of enviroment variable names
135 on Windows to allow '(' and ')' for passing PROGRAMFILES(X86) et.al.
136 unadulterated in 64 bit versions of Windows. PR 46751.
137 trunk patch: http://svn.apache.org/r1705217
138 2.4.x patch: trunk patch works
140 ylavic: As asked on dev@ (in reply to r1705217), what about CVE-2014-6271
141 (shellshock) with unix-like shells (or even maybe native windows
144 *) mod_ssl: Add "no_crl_for_cert_ok" flag to SSLCARevocationCheck directive
145 to opt-in previous behaviour (2.2) with CRLs verification when checking
146 certificate(s) with no corresponding CRL.
147 trunk patch: http://svn.apache.org/r1734561
148 http://svn.apache.org/r1734807
149 http://svn.apache.org/r1735159
150 http://svn.apache.org/r1735337
151 2.4.x patch: trunk works (modulo CHANGES) or
152 http://home.apache.org/~ylavic/patches/httpd-2.4.x-no_crl_for_cert_ok.patch
155 *) mod_proxy_http2: add http2 proxy support in new, experimental module.
156 Includes backport of r1729208 to set ALPN protocols for ssl backend
158 Trunk version of patch: <various>
159 Backport version for 2.4.x of patch: https://www.eissing.org/proxy_http2_2.4v4.patch
161 updated patch after review by cjaillet, merged 1735668,1735748 from trunk
162 updated patch with APLOGNOs by merging 1735931,1735935 from trunk
163 updated patch with APLOGNOs by merging 1735942 from trunk
165 *) CGIVar for controlling building of REQUEST_URI (and future uses)
166 As mentioned on dev@:
167 * This is intended to replace existing methods of configuring how various
168 CGI vars should be built over the long term, though only REQUEST_URI is
170 * If the mechanism should be usable by third-party modules for its own
171 concerns, a check for recognized-envvar can be removed from the command
172 processor and the rest of the code will let the third-party module do
173 the right thing since the rule for a var is a character string in a table,
174 not a separate core_dir_config flag with enumerated values.
175 Trunk patch: r1734947, 1735952
176 2.4.x patch: https://emptyhammock.com/media/downloads/CGIVar-to-2.4.x.txt
177 Bad Jeff: The MMN change was missing originally, same patch updated :(
180 *) mod_ssl: Return 502 instead of 500 when SSL peer check or
181 proxy_post_handshake hook fails.
182 Trunk patch: r1645529 (works)
183 2.4.x patch which adds CHANGES: https://emptyhammock.com/media/downloads/r1645529-to-2.4.x.txt
186 PATCHES/ISSUES THAT ARE BEING WORKED
188 *) http: Don't remove the Content-Length of zero from a HEAD response if
189 it comes from an origin server, module or script. Allow the previous
190 behaviour (for legacy/buggy modules only, not origin) by also backporting
191 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
192 comes for free with the same commit).
193 trunk patch: http://svn.apache.org/r1554303
194 http://svn.apache.org/r1678215
195 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
197 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
198 ints added at the end of core_server_config, the proposed merge
199 does a minor bump only.
200 minfrin: Two new directives need to be documented.
202 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
203 fetching the request body, so to minimize the delay between it is supposed
204 to be alive and the first bytes sent: this is a best effort to prevent the
205 backend from closing because of idle or keepalive timeout in the meantime.
206 Also, handle a new "proxy-flushall" environment variable which allows to
207 flush any forwarded body data immediately. PR 56541+37920.
208 trunk patch: http://svn.apache.org/r1656259
209 http://svn.apache.org/r1656359 (CHANGES entry)
210 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
212 -0: jim: This seems to be a hit to normal performance, to handle an
213 error and/or non-normal condition. The pre-fetch is
214 expensive, and is always done, even before we know that
215 the backend is available to rec' it. I understand the
216 error described, but is the fix actually worth it (plus
217 it seems to allow for a DDoS vector).
218 ylavic: It seems to me that the problem is real since we reuse the
219 connection before prefetching 16K (either controlled by the
220 client, or by an input filter), we currently always prefetch
221 these bytes already. Regarding performance I don't see any
222 difference (more cycles) compared with the current code.
223 However I think I failed to rebuild the header_brigade when
224 the proxy loop is retried (ping), so I need to rework this.
225 Do you think we'd better remove the prefetch, or maybe just
226 make it nonblocking (by default)?
227 jim: Non-blocking seems the best way to handle...
230 PATCHES/ISSUES THAT ARE STALLED
232 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
233 backport keeps syslog logging as part of httpd core and only adds
234 API to allow other modules to be used for error logging.
235 trunk patch: http://svn.apache.org/r1525597
236 http://svn.apache.org/r1525664
237 http://svn.apache.org/r1525845

244 http://svn.apache.org/r1544156
245 http://svn.apache.org/r1626978
246 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-errorlog_provider.patch
248 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
249 needs 2 args which is not valid in ErrorLog manual)
250 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
251 (sorry, haven't finished reviewing completely)
252 jim: What is the status of this??
254 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
255 and ProxyMatch section to distinguish between normal workers and workers
256 with regex substitutions in the name. Implement handling of such workers
257 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
258 matched and used for request. PR 43513.
259 trunk patch: http://svn.apache.org/r1609680
260 http://svn.apache.org/r1609688
261 http://svn.apache.org/r1641381
262 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
263 Also added missing r1609688 to the patchset.
264 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
266 -0: covener tried to review this one in Austin with Jeff. Does the added match function
267 really cover a very narrow set of parameters with the way it skips over backreferences?
268 Also, why a new API vs. just setting the field inline?
270 * mod_systemd: New module, for integration with systemd on Linux.
271 trunk patch: http://svn.apache.org/r1393976
272 http://svn.apache.org/r1393997

277 http://svn.apache.org/r1618579
278 http://svn.apache.org/r1618588
279 2.4.x patch: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
281 sf comments: The IdleShutdown logic seems broken. Consider a single
282 active connection that is stalled for 10 seconds. That
283 connection will be broken after GracefulShutdownTimeout.
284 A better logic would be to check if there is any open
285 connection that is not in keep-alive state.
287 * mod_journald: Add new module mod_journald to log error logs into journald.
288 This patch needs changes done in mod_systemd patch (already
290 trunk patch: http://svn.apache.org/r1610339
291 http://svn.apache.org/r1621806
292 2.4.x patch: http://people.apache.org/~jkaluza/patches/httpd-2.4.x-mod_journald.patch
294 rjung, minfrin: Not understanding "This patch needs changes done in
295 mod_systemd patch", am I right in understanding this patch is
297 jkaluza: No, that patch is not committed yet. It is in STALLED section.
298 The link for that patch is: http://people.apache.org/~jkaluza/patches/mod_systemd/httpd-2.4.x-mod_systemd.patch
300 * core: Add support for systemd socket activation.

310 * mod_proxy: Ensure network errors detected by the proxy are returned as
311 504 Gateway Timout as opposed to 502 Bad Gateway
312 trunk patch: https://svn.apache.org/viewvc?view=revision&revision=1480058
313 2.4.x patch: trunk patch works modulo CHANGES
315 -1: rpluem: This change is still disputed. See
316 http://mail-archives.apache.org/mod_mbox/httpd-dev/201305.mbox/%3C1B16B9E3-87BA-4EEF-939C-7C7313B54714%40gbiv.com%3E
318 * cross-compile: allow to provide CC_FOR_BUILD so that gen_test_char will be
319 compiled by the build compiler instead of the host compiler.
320 Also set CC_FOR_BUILD to 'cc' when cross-compilation is detected.

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

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