3 Changes with Apache 2.3.12
5 *) core: AllowEncodedSlashes new option NoDecode to allow encoded slashes
6 in request URL path info but not decode them. Change behavior of option
7 "On" to decode the encoded slashes as 2.0 and 2.2 do. PR 35256,

14 of bound backend LDAP connections. PR47634 [Eric Covener]
16 *) mod_cache: Make CacheEnable and CacheDisable configurable per
17 directory in addition to per server, making them work from within
18 a LocationMatch. [Graham Leggett]
20 *) worker, event, prefork: Correct several issues when built as
21 DSOs; most notably, the scoreboard was reinitialized during graceful
22 restart, such that processes of the previous generation were not
23 observable. [Jeff Trawick]
25 Changes with Apache 2.3.11
27 *) mod_proxy: balancer-manager now uses POST instead of GET.
30 *) core: new util function: ap_parse_form_data(). Previously,
31 this capability was tucked away in mod_request. [Jim Jagielski]
33 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
35 *) mod_cache: When a request other than GET or HEAD arrives, we must
36 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
39 *) modules: Fix many modules that were not correctly initializing if they
40 were not active during server startup but got enabled later during a
41 graceful restart. [Stefan Fritsch]
43 *) core: Create new ap_state_query function that allows modules to determine
44 if the current configuration run is the initial one at server startup,
45 and if the server is started for testing/config dumping only.
48 *) mod_proxy: Runtime configuration of many parameters for existing
49 balancers via the balancer-manager. [Jim Jagielski]
51 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing
52 balancers via the balancer-manager. [Jim Jagielski]

94 *) mod_ssl: Revamp output buffering to reduce network overhead for
95 output fragmented into many buckets, such as chunked HTTP responses.
98 *) core: Apply <If> sections to all requests, not only to file base requests.
99 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
100 The merging of <If> sections now happens after the merging of <Location>
101 sections, even if an <If> section is embedded inside a <Directory> or
102 <Files> section. [Stefan Fritsch]
104 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
105 and using slotmem. Create foundation for dynamic growth/changes of
106 members within a balancer. Remove BalancerNonce in favor of a
107 per-balancer 'nonce' parameter. [Jim Jagielski]
109 *) mod_status: Don't show slots which are disabled by MaxClients as open.
110 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
112 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
115 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
116 authorization directives were mixed. [Stefan Fritsch]
118 *) mod_authn_socache: change directive name from AuthnCacheProvider
119 to AuthnCacheProvideFor. The term "provider" is overloaded in
120 this module, and we should avoid confusion between the provider
121 of a backend (AuthnCacheSOCache) and the authn provider(s) for
122 which this module provides cacheing (AuthnCacheProvideFor).
125 *) mod_proxy_http: Allocate the fake backend request from a child pool
126 of the backend connection, instead of misusing the pool of the frontend
127 request. Fixes a thread safety issue where buckets set aside in the
128 backend connection leak into other threads, and then disappear when
129 the frontend request is cleaned up, in turn causing corrupted buckets
130 to make other threads spin. [Graham Leggett]
132 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
133 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
134 escape other special characters with backslashes. The old format can
135 still be used with the LegacyDNStringFormat argument to SSLOptions.
137 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
138 scripts and mod_rewrite. [Stefan Fritsch]
140 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
141 RewriteCond. [Stefan Fritsch]
143 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
144 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
146 *) mod_headers: Restore the 2.3.8 and earlier default for the first
147 argument of the Header directive ("onsuccess"). [Eric Covener]
149 *) core: Disallow the mixing of relative and absolute Options PR 33708.
150 [Sönke Tesch <st kino-fahrplan.de>]
152 *) core: When exporting request headers to HTTP_* environment variables,
153 drop variables whose names contain invalid characters. Describe in the
154 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
156 *) core: When selecting an IP-based virtual host, favor an exact match for
157 the port over a wildcard (or omitted) port instead of favoring the one
158 that came first in the configuration file. [Eric Covener]
160 *) core: Overlapping virtual host address/port combinations now implicitly
161 enable name-based virtual hosting for that address. The NameVirtualHost
162 directive has no effect, and _default_ is interpreted the same as "*".
165 *) core: In the absence of any Options directives, the default is now
166 "FollowSymlinks" instead of "All". [Igor Galić]
168 *) rotatelogs: Add -e option to write logs through to stdout for optional
169 further processing. [Graham Leggett]
171 *) mod_ssl: Correctly read full lines in input filter when the line is
172 incomplete during first read. PR 50481. [Ruediger Pluem]
174 *) mod_authz_core: Add AuthzSendForbiddenOnFailure directive to allow
175 sending '403 FORBIDDEN' instead of '401 UNAUTHORIZED' if authorization
176 fails for an authenticated user. PR 40721. [Stefan Fritsch]
178 Changes with Apache 2.3.10
180 *) mod_rewrite: Don't implicitly URL-escape the original query string
181 when no substitution has changed it. PR 50447. [Eric Covener]
183 *) core: Honor 'AcceptPathInfo OFF' during internal redirects,
184 such as per-directory mod_rewrite substitutions. PR 50349.
187 *) mod_rewrite: Add 'RewriteOptions InheritBefore' to put the base
188 rules/conditions before the overridden rules/conditions. PR 39313.

191 *) mod_autoindex: add IndexIgnoreReset to reset the list of IndexIgnored
192 filenames in higher precedence configuration sections. PR 24243.

198 *) core: Fail startup when the argument to ServerName looks like a glob
199 or a regular expression instead of a hostname (*?[]). PR 39863

207 was starting without checking for an existing pidfile. PR 50350

211 backend fails. PR 50332.
212 [Daniel Ruggeri <DRuggeri primary.net>, Ruediger Pluem]
214 *) mod_cache_disk: Fix Windows build which was broken after renaming
215 the module. [Gregg L. Smith]
217 Changes with Apache 2.3.9
219 *) SECURITY: CVE-2010-1623 (cve.mitre.org)
220 Fix a denial of service attack against mod_reqtimeout.
223 *) mod_headers: Change default first argument of Header directive
224 from "onsuccess" to "always". [Eric Covener]
226 *) mod_include: Add the onerror attribute to the include element,
227 allowing an URL to be specified to include on error. [Graham
230 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be
231 consistent with the naming of other modules. [Graham Leggett]
233 *) mod_setenvif: Add SetEnvIfExpr directive to set env var depending on
234 expression. [Stefan Fritsch]
236 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
239 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the
240 binary (Suexec Off), or force startup failure if suEXEC is required
241 but not supported (Suexec On). Change SuexecUserGroup to fail
242 startup instead of just printing a warning if suEXEC is disabled.
245 *) core: Add Error directive for aborting startup or htaccess processing
246 with a specified error message. [Jeff Trawick]
248 *) mod_rewrite: Fix the RewriteEngine directive to work within a
249 location. Previously, once RewriteEngine was switched on globally,
250 it was impossible to switch off. [Graham Leggett]
252 *) core, mod_include, mod_ssl: Move the expression parser derived from
253 mod_include back into mod_include. Replace ap_expr with a parser
254 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
255 ap_expr's public interface and provide hooks for modules to add variables
256 and functions. [Stefan Fritsch]
258 *) core: Do the hook sorting earlier so that the hooks are properly sorted
259 for the pre_config hook and during parsing the config. [Stefan Fritsch]
261 *) core: In the absence of any AllowOverride directives, the default is now
262 "None" instead of "All". PR49823 [Eric Covener]
264 *) mod_proxy: Don't allow ProxyPass or ProxyPassReverse in
265 <Directory> or <Files>. PR47765 [Eric Covener]
267 *) prefork/worker/event MPMS: default value (when no directive is present)
268 of MaxConnectionsPerChild/MaxRequestsPerChild is changed to 0 from 10000
269 to match default configuration and manual. PR47782 [Eric Covener]
271 *) proxy_connect: Don't give up in the middle of a CONNECT tunnel
272 when the child process is starting to exit. PR50220. [Eric Covener]
274 *) mod_autoindex: Fix inheritance of mod_autoindex directives into
275 contexts that don't have any mod_autoindex directives. PR47766.
278 *) mod_rewrite: Add END flag for RewriteRule to prevent further rounds
279 of rewrite processing when a per-directory substitution occurs.
282 *) mod_ssl: Make sure to always log an error if loading of CA certificates
283 fails. PR 40312. [Paul Tiemann <issues apache org ourdetour com>]
285 *) mod_dav: Send 501 error if unknown Content-* header is received for a PUT
286 request (RFC 2616 9.6). PR 42978. [Stefan Fritsch]
288 *) mod_dav: Send 400 error if malformed Content-Range header is received for
289 a put request (RFC 2616 14.16). PR 49825. [Stefan Fritsch]
291 *) mod_proxy: Release the backend connection as soon as EOS is detected,
292 so the backend isn't forced to wait for the client to eventually
293 acknowledge the data. [Graham Leggett]
295 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
296 per-directory, and chosen during the location walk. Make ProxyPass
297 work correctly from within a LocationMatch. [Graham Leggett]
299 *) core: Fix segfault if per-module LogLevel is on virtual host
300 scope. PR 50117. [Stefan Fritsch]
302 *) mod_proxy: Move the ProxyErrorOverride directive to have per
303 directory scope. [Graham Leggett]
305 *) mod_allowmethods: New module to deny certain HTTP methods without
306 interfering with authentication/authorization. [Paul Querna,
307 Igor Galić, Stefan Fritsch]
309 *) mod_ssl: Log certificate information and improve error message if client
310 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
313 *) htcacheclean: Teach htcacheclean to limit cache size by number of
314 inodes in addition to size of files. Prevents a cache disk from
315 running out of space when many small files are cached.
318 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
319 describes more accurately what the directive does. The old name
320 still works but logs a warning. [Stefan Fritsch]
322 *) mod_cache: Optionally serve stale data when a revalidation returns a
323 5xx response, controlled by the CacheStaleOnError directive.
326 *) htcacheclean: Allow the listing of valid URLs within the cache, with
327 the option to list entry metadata such as sizes and times. [Graham
330 *) mod_cache: correctly parse quoted strings in cache headers.
333 *) mod_cache: Allow control over the base URL of reverse proxied requests
334 using the CacheKeyBaseURL directive, so that the cache key can be
335 calculated from the endpoint URL instead of the server URL. [Graham
338 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
339 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
340 CacheMinExpire and CacheMaxExpire can be set per directory/location.
343 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and
344 CacheReadTime can be set per directory/location. [Graham Leggett]
346 *) core: Speed up config parsing if using a very large number of config
347 files. PR 50002 [andrew cloudaccess net]
349 *) mod_cache: Support the caching of HEAD requests. [Graham Leggett]
351 *) htcacheclean: Allow the option to round up file sizes to a given
352 block size, improving the accuracy of disk usage. [Graham Leggett]
354 *) mod_ssl: Add authz providers for use with mod_authz_core and its
355 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
356 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
357 'ssl-require' (expressions with same syntax as SSLRequire).
360 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
361 bison instead of yacc. [Stefan Fritsch]
363 *) mod_disk_cache: Change on-disk header file format to support the
364 link of the device/inode of the data file to the matching header
365 file, and to support the option of not writing a data file when
366 the data file is empty. [Graham Leggett]
368 *) core/mod_unique_id: Add generate_log_id hook to allow to use
369 the ID generated by mod_unique_id as error log ID for requests.
372 *) mod_cache: Make sure that we never allow a 304 Not Modified response
373 that we asked for to leak to the client should the 304 response be
374 uncacheable. PR45341 [Graham Leggett]
376 *) mod_cache: Add the cache_status hook to register the final cache
377 decision hit/miss/revalidate. Add optional support for an X-Cache
378 and/or an X-Cache-Detail header to add the cache status to the
379 response. PR48241 [Graham Leggett]
381 *) mod_authz_host: Add 'local' provider that matches connections originating
382 on the local host. PR 19938. [Stefan Fritsch]
384 *) Event MPM: Fix crash accessing pollset on worker thread when child
385 process is exiting. [Jeff Trawick]
387 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
388 pass the system library path (LD_LIBRARY_PATH or platform-specific
389 variables) along with the system PATH, by default. Both should be
390 overridden together as desired using PassEnv etc; see mod_env.
393 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
394 capture a stale backend response, perform If-Modified-Since requests
395 against the backend, and serving from the cache all 304 responses.
396 This restores pre-2.2.4 cache behavior. [William Rowe]
398 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
399 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
400 the ambiguity of the symlink test "-ltest", introduce -h or -L as
401 symlink test operators. [William Rowe]
403 *) mod_cache: Give the cache provider the opportunity to choose to cache
404 or not cache based on the buckets present in the brigade, such as the
405 presence of a FILE bucket.
408 *) mod_authz_core: Allow authz providers to check args while reading the
409 config and allow to cache parsed args. Move 'all' and 'env' authz
410 providers from mod_authz_host to mod_authz_core. Add 'method' authz
411 provider depending on the HTTP method. [Stefan Fritsch]
413 *) mod_include: Move the request_rec within mod_include to be
414 exposed within include_ctx_t. [Graham Leggett]
416 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
417 variable being echoed or set to be decoded and then encoded as separate
418 steps. PR47686 [Graham Leggett]
420 *) mod_cache: Add a discrete commit_entity() provider function within the
421 mod_cache provider interface which is called to indicate to the
422 provider that caching is complete, giving the provider the opportunity
423 to commit temporary files permanently to the cache in an atomic
424 fashion. Replace the inconsistent use of error cleanups with a formal
425 set of pool cleanups attached to a subpool, which is destroyed on error.
428 *) mod_cache: Change the signature of the store_body() provider function
429 within the mod_cache provider interface to support an "in" brigade
430 and an "out" brigade instead of just a single input brigade. This
431 gives a cache provider the option to consume only part of the brigade
432 passed to it, rather than the whole brigade as was required before.
433 This fixes an out of memory and a request timeout condition that would
434 occur when the original document was a large file. Introduce
435 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
436 the amount of data to attempt to cache at a time. [Graham Leggett]
438 *) core: Add ErrorLogFormat to allow configuring error log format, including
439 additional information that is logged once per connection or request. Add
440 error log IDs for connections and request to allow correlating error log
441 lines and the corresponding access log entry. [Stefan Fritsch]
443 *) core: Disable sendfile by default. [Stefan Fritsch]
445 *) mod_cache: Check the request to determine whether we are allowed
446 to return cached content at all, and respect a "Cache-Control:
447 no-cache" header from a client. Previously, "no-cache" would
448 behave like "max-age=0". [Graham Leggett]
450 *) mod_cache: Use a proper filter context to hold filter data instead
451 of misusing the per-request configuration. Fixes a segfault on trunk
452 when the normal handler is used. [Graham Leggett]
454 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
455 it is too long. PR 49388. [Stefan Fritsch]
457 *) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
458 and non-* ports on NameVirtualHost, or multiple NameVirtualHost
459 directives for the same address:port, or NameVirtualHost
460 directives with no matching VirtualHosts, or multiple ip-based
461 VirtualHost sections for the same address:port. These were
462 previously accepted with a warning, but the behavior was
463 undefined. [Dan Poirier]

1671 *) mod_disk_cache: If possible, check if the size of an object to cache is
1672 within the configured boundaries before actually saving data.
1673 [Niklas Edmundsson <nikke acc.umu.se>]
1675 *) Worker and event MPMs: Remove improper scoreboard updates which were
1676 performed in the event of a fork() failure. [Chris Darroch]
1678 *) Add support for fcgi:// proxies to mod_rewrite.
1679 [Markus Schiegl <ms schiegl.com>]
1681 *) Remove incorrect comments from scoreboard.h regarding conditional
1682 loading of worker_score structure with mod_status, and remove unused
1683 definitions relating to old life_status field.
1684 [Chris Darroch <chrisd pearsoncmg.com>]
1686 *) Remove allocation of memory for unused array of lb_score pointers
1687 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
1689 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
1690 [Garrett Rooney, Jim Jagielski, Paul Querna]
1692 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
1693 [Chris Darroch <chrisd pearsoncmg.com>]
1695 *) mod_charset_lite: Remove Content-Length when output filter can
1696 invalidate it. Warn when input filter can invalidate it.
1699 *) Authz: Add the new module mod_authn_core that will provide common
1700 authn directives such as 'AuthType', 'AuthName'. Move the directives
1701 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1702 into mod_authn_core. [Brad Nicholes]
1704 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
1705 into the new module mod_access_compat which can be loaded to provide
1706 support for these directives.
1709 *) Authz: Move the 'Require' directive from the core module as well as
1710 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
1711 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
1712 logic into the authorization processing. [Brad Nicholes]
1714 *) Authz: Add the new module mod_authz_core which acts as the
1715 authorization provider vector and contains common authz
1716 directives. [Brad Nicholes]
1718 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1719 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
1721 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1722 host-based access control provided by mod_authz_host and invoked
1723 through the 'Require' directive. [Brad Nicholes]
1725 *) Authz: Convert all of the authz modules from hook based to
1726 provider based. [Brad Nicholes]
1728 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
1729 seconds to cache a document.
1730 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
1732 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
1734 *) Fix typo in ProxyStatus syntax error message.
1735 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
1737 *) Asynchronous write completion for the Event MPM. [Brian Pane]
1739 *) Added an End-Of-Request bucket type. The logging of a request and
1740 the freeing of its pool are now done when the EOR bucket is destroyed.
1741 This has the effect of delaying the logging until right after the last
1742 of the response is sent; ap_core_output_filter() calls the access logger
1743 indirectly when it destroys the EOR bucket. [Brian Pane]
1745 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1746 and the format of statistical output has changed. [Colm MacCarthaigh]
1748 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1750 *) Added new connection states for handler and write completion
1753 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1756 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1757 allowing string-valued client certificate attributes to be used for
1758 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
