3 Changes with Apache 2.3.11
5 *) mod_cache: When a request other than GET or HEAD arrives, we must
6 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
9 *) modules: Fix many modules that were not correctly initializing if they
10 were not active during server startup but got enabled later during a
11 graceful restart. [Stefan Fritsch]
13 *) core: Create new ap_state_query function that allows modules to determine
14 if the current configuration run is the initial one at server startup,
15 and if the server is started for testing/config dumping only.
18 *) mod_cache: When a bad Expires date is present, we need to behave as if
19 the Expires is in the past, not as if the Expires is missing. PR 16521.

22 *) mod_cache: We must ignore quoted-string values that appear in a
23 Cache-Control header. PR 50199. [Graham Leggett]
25 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
26 received for a PUT request. PR 42978. [Stefan Fritsch]
28 *) mod_cache: Respect s-maxage as described by RFC2616 14.9.3, which must
29 take precedence if present. PR 35247. [Graham Leggett]
31 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
32 are configured with the same ServerName and private key file.

42 PR 50434 [Stefan Fritsch]
44 *) core: Add support to set variables with the 'Define' directive. The
45 variables that can then be used in the config using the ${VAR} syntax
46 known from envvar interpolation. [Stefan Fritsch]
48 *) mod_proxy_http: make adding of X-Forwarded-* headers configurable.
49 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
51 *) mod_slotmem_shm: Increase memory alignment for slotmem data.
54 *) mod_ssl: Add config options for OCSP: SSLOCSPResponderTimeout,
55 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
56 [Kaspar Brand <httpd-dev.2011 velox.ch>]
58 *) mod_ssl: Revamp output buffering to reduce network overhead for
59 output fragmented into many buckets, such as chunked HTTP responses.
62 *) core: Apply <If> sections to all requests, not only to file base requests.
63 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
64 The merging of <If> sections now happens after the merging of <Location>
65 sections, even if an <If> section is embedded inside a <Directory> or
66 <Files> section. [Stefan Fritsch]
68 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
69 and using slotmem. Create foundation for dynamic growth/changes of
70 members within a balancer. Remove BalancerNonce in favor of a
71 per-balancer 'nonce' parameter. [Jim Jagielski]
73 *) mod_status: Don't show slots which are disabled by MaxClients as open.
74 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
76 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
79 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
80 authorization directives were mixed. [Stefan Fritsch]
82 *) mod_authn_socache: change directive name from AuthnCacheProvider
83 to AuthnCacheProvideFor. The term "provider" is overloaded in
84 this module, and we should avoid confusion between the provider
85 of a backend (AuthnCacheSOCache) and the authn provider(s) for
86 which this module provides cacheing (AuthnCacheProvideFor).
89 *) mod_proxy_http: Allocate the fake backend request from a child pool
90 of the backend connection, instead of misusing the pool of the frontend
91 request. Fixes a thread safety issue where buckets set aside in the
92 backend connection leak into other threads, and then disappear when
93 the frontend request is cleaned up, in turn causing corrupted buckets
94 to make other threads spin. [Graham Leggett]
96 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
97 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
98 escape other special characters with backslashes. The old format can
99 still be used with the LegacyDNStringFormat argument to SSLOptions.
101 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
102 scripts and mod_rewrite. [Stefan Fritsch]
104 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
105 RewriteCond. [Stefan Fritsch]
107 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
108 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
110 *) mod_headers: Restore the 2.3.8 and earlier default for the first
111 argument of the Header directive ("onsuccess"). [Eric Covener]
113 *) core: Disallow the mixing of relative and absolute Options PR 33708.
114 [Sönke Tesch <st kino-fahrplan.de>]
116 *) core: When exporting request headers to HTTP_* environment variables,
117 drop variables whose names contain invalid characters. Describe in the
118 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
120 *) core: When selecting an IP-based virtual host, favor an exact match for
121 the port over a wildcard (or omitted) port instead of favoring the one
122 that came first in the configuration file. [Eric Covener]
124 *) core: Overlapping virtual host address/port combinations now implicitly
125 enable name-based virtual hosting for that address. The NameVirtualHost
126 directive has no effect, and _default_ is interpreted the same as "*".
129 *) core: In the absence of any Options directives, the default is now
130 "FollowSymlinks" instead of "All". [Igor Galić]
132 *) rotatelogs: Add -e option to write logs through to stdout for optional
133 further processing. [Graham Leggett]
135 *) mod_ssl: Correctly read full lines in input filter when the line is
136 incomplete during first read. PR 50481. [Ruediger Pluem]
138 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
139 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
140 fails for an authenticated user. PR 40721. [Stefan Fritsch]
142 Changes with Apache 2.3.10
144 *) mod_rewrite: Don't implicitly URL-escape the original query string
145 when no substitution has changed it. PR 50447. [Eric Covener]
147 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
148 such as per-directory mod_rewrite substitutions. PR 50349.
151 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
152 rules/conditions before the overridden rules/conditions. PR 39313.
153 [Jérôme Grandjanny <jerome.grandjanny cea.fr>]
155 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored
156 filenames in higher precedence configuration sections. PR 24243.
159 *) mod_cgid: RLimit* directive support for mod_cgid. PR 42135
162 *) core: Fail startup when the argument to ServerName looks like a glob
163 or a regular expression instead of a hostname (*?[]). PR 39863
164 [Rahul Nair <rahul.g.nair gmail.com>]
166 *) mod_userdir: Add merging of enable, disable, and filename arguments
167 to UserDir directive, leaving enable/disable of userlists unmerged.
168 PR 44076 [Eric Covener]
170 *) httpd: When no -k option is provided on the httpd command line, the server
171 was starting without checking for an existing pidfile. PR 50350
174 *) mod_proxy: Put the worker in error state if the SSL handshake with the
175 backend fails. PR 50332.
176 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
178 *) mod_cache_disk: Fix Windows build which was broken after renaming
179 the module. [Gregg L. Smith]
181 Changes with Apache 2.3.9
183 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
184 Fix a denial of service attack against mod_reqtimeout.
187 *) mod_headers: Change default first argument of Header directive
188 from "onsuccess" to "always". [Eric Covener]
190 *) mod_include: Add the onerror attribute to the include element,
191 allowing an URL to be specified to include on error. [Graham
194 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
195 consistent with the naming of other modules. [Graham Leggett]
197 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
198 expression. [Stefan Fritsch]
200 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
203 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
204 binary (Suexec Off), or force startup failure if suEXEC is required
205 but not supported (Suexec On). Change SuexecUserGroup to fail
206 startup instead of just printing a warning if suEXEC is disabled.
209 *) core: Add Error directive for aborting startup or htaccess processing
210 with a specified error message. [Jeff Trawick]
212 *) mod_rewrite: Fix the RewriteEngine directive to work within a
213 location. Previously, once RewriteEngine was switched on globally,
214 it was impossible to switch off. [Graham Leggett]
216 *) core, mod_include, mod_ssl: Move the expression parser derived from
217 mod_include back into mod_include. Replace ap_expr with a parser
218 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
219 ap_expr's public interface and provide hooks for modules to add variables
220 and functions. [Stefan Fritsch]
222 *) core: Do the hook sorting earlier so that the hooks are properly sorted
223 for the pre_config hook and during parsing the config. [Stefan Fritsch]
225 *) core: In the absence of any AllowOverride directives, the default is now
226 "None" instead of "All". PR49823 [Eric Covener]
228 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
229 <Directory> or <Files>. PR47765 [Eric Covener]
231 *) prefork/worker/event MPMS: default value (when no directive is present)
232 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
233 to match default configuration and manual. PR47782 [Eric Covener]
235 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
236 when the child process is starting to exit. PR50220. [Eric Covener]
238 *) mod_autoindex: Fix inheritance of mod_autoindex directives into
239 contexts that don't have any mod_autoindex directives. PR47766.
242 *) mod_rewrite: Add END flag for RewriteRule to prevent further rounds
243 of rewrite processing when a per-directory substitution occurs.
246 *) mod_ssl: Make sure to always log an error if loading of CA certificates
247 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
249 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
250 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
252 *) mod_dav: Send 400 error if malformed Content-Range header is received for
253 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
255 *) mod_proxy: Release the backend connection as soon as EOS is detected,
256 so the backend isn't forced to wait for the client to eventually
257 acknowledge the data. [Graham Leggett]
259 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
260 per-directory, and chosen during the location walk. Make ProxyPass
261 work correctly from within a LocationMatch. [Graham Leggett]
263 *) core: Fix segfault if per-module LogLevel is on virtual host
264 scope. PR 50117. [Stefan Fritsch]
266 *) mod_proxy: Move the ProxyErrorOverride directive to have per
267 directory scope. [Graham Leggett]
269 *) mod_allowmethods: New module to deny certain HTTP methods without
270 interfering with authentication/authorization. [Paul Querna,
271 Igor Galić, Stefan Fritsch]
273 *) mod_ssl: Log certificate information and improve error message if client
274 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
277 *) htcacheclean: Teach htcacheclean to limit cache size by number of
278 inodes in addition to size of files. Prevents a cache disk from
279 running out of space when many small files are cached.
282 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
283 describes more accurately what the directive does. The old name
284 still works but logs a warning. [Stefan Fritsch]
286 *) mod_cache: Optionally serve stale data when a revalidation returns a
287 5xx response, controlled by the CacheStaleOnError directive.
290 *) htcacheclean: Allow the listing of valid URLs within the cache, with
291 the option to list entry metadata such as sizes and times. [Graham
294 *) mod_cache: correctly parse quoted strings in cache headers.
297 *) mod_cache: Allow control over the base URL of reverse proxied requests
298 using the CacheKeyBaseURL directive, so that the cache key can be
299 calculated from the endpoint URL instead of the server URL. [Graham
302 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
303 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
304 CacheMinExpire and CacheMaxExpire can be set per directory/location.
307 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
308 CacheReadTime can be set per directory/location. [Graham Leggett]
310 *) core: Speed up config parsing if using a very large number of config
311 files. PR 50002 [andrew cloudaccess net]
313 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
315 *) htcacheclean: Allow the option to round up file sizes to a given
316 block size, improving the accuracy of disk usage. [Graham Leggett]
318 *) mod_ssl: Add authz providers for use with mod_authz_core and its
319 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
320 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
321 'ssl-require' (expressions with same syntax as SSLRequire).
324 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
325 bison instead of yacc. [Stefan Fritsch]
327 *) mod_disk_cache: Change on-disk header file format to support the
328 link of the device/inode of the data file to the matching header
329 file, and to support the option of not writing a data file when
330 the data file is empty. [Graham Leggett]
332 *) core/mod_unique_id: Add generate_log_id hook to allow to use
333 the ID generated by mod_unique_id as error log ID for requests.
336 *) mod_cache: Make sure that we never allow a 304 Not Modified response
337 that we asked for to leak to the client should the 304 response be
338 uncacheable. PR45341 [Graham Leggett]
340 *) mod_cache: Add the cache_status hook to register the final cache
341 decision hit/miss/revalidate. Add optional support for an X-Cache
342 and/or an X-Cache-Detail header to add the cache status to the
343 response. PR48241 [Graham Leggett]
345 *) mod_authz_host: Add 'local' provider that matches connections originating
346 on the local host. PR 19938. [Stefan Fritsch]
348 *) Event MPM: Fix crash accessing pollset on worker thread when child
349 process is exiting. [Jeff Trawick]
351 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
352 pass the system library path (LD_LIBRARY_PATH or platform-specific
353 variables) along with the system PATH, by default. Both should be
354 overridden together as desired using PassEnv etc; see mod_env.
357 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
358 capture a stale backend response, perform If-Modified-Since requests
359 against the backend, and serving from the cache all 304 responses.
360 This restores pre-2.2.4 cache behavior. [William Rowe]
362 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
363 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
364 the ambiguity of the symlink test "-ltest", introduce -h or -L as
365 symlink test operators. [William Rowe]
367 *) mod_cache: Give the cache provider the opportunity to choose to cache
368 or not cache based on the buckets present in the brigade, such as the
369 presence of a FILE bucket.
372 *) mod_authz_core: Allow authz providers to check args while reading the
373 config and allow to cache parsed args. Move 'all' and 'env' authz
374 providers from mod_authz_host to mod_authz_core. Add 'method' authz
375 provider depending on the HTTP method. [Stefan Fritsch]
377 *) mod_include: Move the request_rec within mod_include to be
378 exposed within include_ctx_t. [Graham Leggett]
380 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
381 variable being echoed or set to be decoded and then encoded as separate
382 steps. PR47686 [Graham Leggett]
384 *) mod_cache: Add a discrete commit_entity() provider function within the
385 mod_cache provider interface which is called to indicate to the
386 provider that caching is complete, giving the provider the opportunity
387 to commit temporary files permanently to the cache in an atomic
388 fashion. Replace the inconsistent use of error cleanups with a formal
389 set of pool cleanups attached to a subpool, which is destroyed on error.
392 *) mod_cache: Change the signature of the store_body() provider function
393 within the mod_cache provider interface to support an "in" brigade
394 and an "out" brigade instead of just a single input brigade. This
395 gives a cache provider the option to consume only part of the brigade
396 passed to it, rather than the whole brigade as was required before.
397 This fixes an out of memory and a request timeout condition that would
398 occur when the original document was a large file. Introduce
399 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
400 the amount of data to attempt to cache at a time. [Graham Leggett]
402 *) core: Add ErrorLogFormat to allow configuring error log format, including
403 additional information that is logged once per connection or request. Add
404 error log IDs for connections and request to allow correlating error log
405 lines and the corresponding access log entry. [Stefan Fritsch]
407 *) core: Disable sendfile by default. [Stefan Fritsch]
409 *) mod_cache: Check the request to determine whether we are allowed
410 to return cached content at all, and respect a "Cache-Control:
411 no-cache" header from a client. Previously, "no-cache" would
412 behave like "max-age=0". [Graham Leggett]
414 *) mod_cache: Use a proper filter context to hold filter data instead
415 of misusing the per-request configuration. Fixes a segfault on trunk
416 when the normal handler is used. [Graham Leggett]
418 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
419 it is too long. PR 49388. [Stefan Fritsch]
421 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
422 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
423 directives for the same address:port, or NameVirtualHost
424 directives with no matching VirtualHosts, or multiple ip-based
425 VirtualHost sections for the same address:port. These were
426 previously accepted with a warning, but the behavior was
427 undefined. [Dan Poirier]
429 *) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
430 Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
432 *) core: DirectoryMatch can now match on the end of line character ($),
433 and sub-directories of matched directories are no longer implicitly

1669 into the new module mod_access_compat which can be loaded to provide
1670 support for these directives.
1673 *) Authz: Move the 'Require' directive from the core module as well as
1674 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1675 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1676 logic into the authorization processing. [Brad Nicholes]
1678 *) Authz: Add the new module mod_authz_core which acts as the
1679 authorization provider vector and contains common authz
1680 directives. [Brad Nicholes]
1682 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1683 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1685 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1686 host-based access control provided by mod_authz_host and invoked
1687 through the 'Require' directive. [Brad Nicholes]
1689 *) Authz: Convert all of the authz modules from hook based to
1690 provider based. [Brad Nicholes]
1692 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1693 seconds to cache a document.
1694 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
1696 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
1698 *) Fix typo in ProxyStatus syntax error message.
1699 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1701 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1703 *) Added an End-Of-Request bucket type. The logging of a request and
1704 the freeing of its pool are now done when the EOR bucket is destroyed.
1705 This has the effect of delaying the logging until right after the last
1706 of the response is sent; ap_core_output_filter() calls the access logger
1707 indirectly when it destroys the EOR bucket. [Brian Pane]
1709 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1710 and the format of statistical output has changed. [Colm MacCarthaigh]
1712 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1714 *) Added new connection states for handler and write completion
1717 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1720 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1721 allowing string-valued client certificate attributes to be used for
1722 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
