88 CURRENT RELEASE NOTES:
90 * Forward binary compatibility is expected of Apache 2.4.x releases, such
91 that no MMN major number changes will occur after 2.4.1. Such changes can
92 only be made in the trunk.
94 * All commits to branches/2.4.x must be reflected in SVN trunk,
95 as well, if they apply. Logical progression is commit to trunk
96 then merge into branches/2.4.x, as applicable.
98 * Current exceptions for RTC for this branch:
102 . non-Unix, single-platform code
104 RELEASE SHOWSTOPPERS:
106 *) core: Allow spaces after chunk-size for compatibility with implementations
107 using a pre-filled buffer, and log parsing failures at level INFO.

112 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_http_filter_chunked-v2.patch
113 (trunk works modulo CHANGES, above is to ease review only)
115 -1: wrowe; 'parsing' variable is not present in trunk, is unnecessary
116 1685339 was previously approved, so simply apply it already.
117 ylavic: r1685339 applied, patch updated to v2.
118 'parsing' is not necessary in trunk but is in 2.4.x because of
122 PATCHES ACCEPTED TO BACKPORT FROM TRUNK:
123 [ start all new proposals below, under PATCHES PROPOSED. ]
128 PATCHES PROPOSED TO BACKPORT FROM TRUNK:
129 [ New proposals should be added at the end of the list ]
131 * mod_proxy: Add ap_proxy_define_match_worker() and use it for ProxyPassMatch
132 and ProxyMatch section to distinguish between normal workers and workers
133 with regex substitutions in the name. Implement handling of such workers
134 in ap_proxy_get_worker(). Fixes the bug when regex workers were not
135 matched and used for request. PR 43513.

137 http://svn.apache.org/r1609688
138 http://svn.apache.org/r1641381
139 ylavic: Merge patch provided (reusing new->real to avoid double de_socketfy() call).
140 Also added missing r1609688 to the patchset.
141 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-ap_proxy_define_match_worker.patch
143 -0: covener tried to review this one in Austin with Jeff. Does the added match function
144 really cover a very narrow set of parameters with the way it skips over backreferences?
145 Also, why a new API vs. just setting the field inline?
147 * core: Add ap_errorlog_provider to make ErrorLog logging modular. This
148 backport keeps syslog logging as part of httpd core and only adds
149 API to allow other modules to be used for error logging.

163 +1: covener w/ doc or code to fix syntax (providername:providerarg not supported like syslog or socacheproviders,
164 needs 2 args which is not valid in ErrorLog manual)
165 trawick: nit: fix "writing" in "/* NULL if we are writting to syslog */"
166 (sorry, haven't finished reviewing completely)
168 * mod_journald: Add new module mod_journald to log error logs into journald.

200 *) http: Don't remove the Content-Length of zero from a HEAD response if
201 it comes from an origin server, module or script. Allow the previous
202 behaviour (for legacy/buggy modules only, not origin) by also backporting
203 the HttpContentLengthHeadZero directive (and also HttpExpectStrict which
204 comes for free with the same commit).

207 2.4.x patch: http://people.apache.org/~ylavic/httpd-2.4.x-preserve_head_cl_zero.patch
209 ylavic: r1554303 issued a major MMN bump, but since the ABI change is two
210 ints added at the end of core_server_config, the proposed merge
211 does a minor bump only.
213 *) mod_substitute: Fix configuraton merge order. PR 57641
214 trunk patch: http://svn.apache.org/r1684900
215 2.4.x patch: trunk works (modulo CHANGES)

249 * mod_proxy_http: Don't establish or reuse a backend connection before pre-
250 fetching the request body, so to minimize the delay between it is supposed
251 to be alive and the first bytes sent: this is a best effort to prevent the
252 backend from closing because of idle or keepalive timeout in the meantime.
253 Also, handle a new "proxy-flushall" environment variable which allows to
254 flush any forwarded body data immediately. PR 56541+37920.
255 trunk patch: http://svn.apache.org/r1656259
256 http://svn.apache.org/r1656359 (CHANGES entry)
257 2.4.x patch: trunk works (modulo CHANGES, docs/log-message-tags)
259 -0: jim: This seems to be a hit to normal performance, to handle an
260 error and/or non-normal condition. The pre-fetch is
261 expensive, and is always done, even before we know that
262 the backend is available to rec' it. I understand the
263 error described, but is the fix actually worth it (plus
264 it seems to allow for a DDoS vector).
265 ylavic: It seems to me that the problem is real since we reuse the
266 connection before prefetching 16K (either controlled by the
267 client, or by an input filter), we currently always prefetch
268 these bytes already. Regarding performance I don't see any
269 difference (more cycles) compared with the current code.
270 However I think I failed to rebuild the header_brigade when
271 the proxy loop is retried (ping), so I need to rework this.
272 Do you think we'd better remove the prefetch, or maybe just
273 make it nonblocking (by default)?
274 jim: Non-blocking seems the best way to handle...

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