154 'reallyall'. [Stefan Fritsch]
156 *) mod_rewrite: Check validity of each internal (int:) RewriteMap even if the

214 *) mod_allowmethods: Correct Merging of "reset" and do not allow an
215 empty parameter list for the AllowMethods directive. [Rainer Jung]
217 *) configure: Update selection of modules for 'all' and 'most'. 'all' will

219 selection for 'most' more useful (including ssl and proxy). Both 'all'
220 and 'most' will now disable modules if dependencies are missing instead
221 of aborting. If a specific module is requested with --enable-XXX=yes,
222 missing dependencies will still cause configure to exit with an error.
225 *) mod_ldap: Revert the integration of apr-ldap as ap_ldap which was done
226 in 2.3.13. [Stefan Fritsch]

283 they have been enabled implicitely. [Rainer Jung]
285 *) configure: Allow to specify module specific custom linker flags via
286 the MOD_XXX_LDADD variables. [Rainer Jung]
288 Changes with Apache 2.3.13

299 *) prefork, worker, event: Rename MaxClients to MaxRequestWorkers which
300 describes more accurately what it does. [Stefan Fritsch]
302 *) rotatelogs: Add -p argument to specify custom program to invoke
303 after a log rotation. PR 51285. [Sven Ulland <sveniu ifi.uio.no>,

318 *) mpm_event: Process lingering close asynchronously instead of tying up
319 worker threads. [Jeff Trawick, Stefan Fritsch]

356 mode that does not allow to bypass request access restrictions; new
357 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
358 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
359 the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
360 data entry. [Stefan Fritsch]
362 *) mod_include: Merge directory configs instead of one SSI* config directive
363 causing all other per-directory SSI* config directives to be reset.
366 *) mod_charset_lite: Remove DebugLevel option in favour of per-module
367 loglevel. [Stefan Fritsch]

413 MPM child of a generation exits. [Jeff Trawick]
415 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
416 process as opposed to disabling caching completely. This allows to use
417 the non-shared-memory cache as a workaround for the shared memory cache
418 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
420 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
421 necessary if a module (like mod_perl) registers additional modules late
422 in the startup phase. [Stefan Fritsch]

476 directory in addition to per server, making them work from within
477 a LocationMatch. [Graham Leggett]
479 *) worker, event, prefork: Correct several issues when built as
480 DSOs; most notably, the scoreboard was reinitialized during graceful

482 observable. [Jeff Trawick]
484 Changes with Apache 2.3.11
486 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
487 Win32's cscript interpreter can only use a single quote as comment char.

503 were not active during server startup but got enabled later during a
504 graceful restart. [Stefan Fritsch]

581 *) mod_authn_socache: change directive name from AuthnCacheProvider
582 to AuthnCacheProvideFor. The term "provider" is overloaded in
583 this module, and we should avoid confusion between the provider
584 of a backend (AuthnCacheSOCache) and the authn provider(s) for
585 which this module provides cacheing (AuthnCacheProvideFor).
588 *) mod_proxy_http: Allocate the fake backend request from a child pool
589 of the backend connection, instead of misusing the pool of the frontend
590 request. Fixes a thread safety issue where buckets set aside in the
591 backend connection leak into other threads, and then disappear when
592 the frontend request is cleaned up, in turn causing corrupted buckets
593 to make other threads spin. [Graham Leggett]
595 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
596 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
597 escape other special characters with backslashes. The old format can
598 still be used with the LegacyDNStringFormat argument to SSLOptions.

777 inodes in addition to size of files. Prevents a cache disk from
778 running out of space when many small files are cached.
781 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
782 describes more accurately what the directive does. The old name
783 still works but logs a warning. [Stefan Fritsch]
785 *) mod_cache: Optionally serve stale data when a revalidation returns a
786 5xx response, controlled by the CacheStaleOnError directive.

790 the option to list entry metadata such as sizes and times. [Graham
793 *) mod_cache: correctly parse quoted strings in cache headers.

814 *) htcacheclean: Allow the option to round up file sizes to a given
815 block size, improving the accuracy of disk usage. [Graham Leggett]
817 *) mod_ssl: Add authz providers for use with mod_authz_core and its
818 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
819 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
820 'ssl-require' (expressions with same syntax as SSLRequire).
823 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
824 bison instead of yacc. [Stefan Fritsch]
826 *) mod_disk_cache: Change on-disk header file format to support the
827 link of the device/inode of the data file to the matching header
828 file, and to support the option of not writing a data file when
829 the data file is empty. [Graham Leggett]
831 *) core/mod_unique_id: Add generate_log_id hook to allow to use
832 the ID generated by mod_unique_id as error log ID for requests.
835 *) mod_cache: Make sure that we never allow a 304 Not Modified response
836 that we asked for to leak to the client should the 304 response be
837 uncacheable. PR45341 [Graham Leggett]
839 *) mod_cache: Add the cache_status hook to register the final cache
840 decision hit/miss/revalidate. Add optional support for an X-Cache
841 and/or an X-Cache-Detail header to add the cache status to the
842 response. PR48241 [Graham Leggett]
844 *) mod_authz_host: Add 'local' provider that matches connections originating
845 on the local host. PR 19938. [Stefan Fritsch]
847 *) Event MPM: Fix crash accessing pollset on worker thread when child
848 process is exiting. [Jeff Trawick]
850 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
851 pass the system library path (LD_LIBRARY_PATH or platform-specific
852 variables) along with the system PATH, by default. Both should be
853 overridden together as desired using PassEnv etc; see mod_env.
856 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
857 capture a stale backend response, perform If-Modified-Since requests
858 against the backend, and serving from the cache all 304 responses.
859 This restores pre-2.2.4 cache behavior. [William Rowe]
861 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
862 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
863 the ambiguity of the symlink test "-ltest", introduce -h or -L as
864 symlink test operators. [William Rowe]
866 *) mod_cache: Give the cache provider the opportunity to choose to cache
867 or not cache based on the buckets present in the brigade, such as the
868 presence of a FILE bucket.
871 *) mod_authz_core: Allow authz providers to check args while reading the
872 config and allow to cache parsed args. Move 'all' and 'env' authz
873 providers from mod_authz_host to mod_authz_core. Add 'method' authz
874 provider depending on the HTTP method. [Stefan Fritsch]
876 *) mod_include: Move the request_rec within mod_include to be
877 exposed within include_ctx_t. [Graham Leggett]
879 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
880 variable being echoed or set to be decoded and then encoded as separate
881 steps. PR47686 [Graham Leggett]
883 *) mod_cache: Add a discrete commit_entity() provider function within the
884 mod_cache provider interface which is called to indicate to the
885 provider that caching is complete, giving the provider the opportunity
886 to commit temporary files permanently to the cache in an atomic
887 fashion. Replace the inconsistent use of error cleanups with a formal
888 set of pool cleanups attached to a subpool, which is destroyed on error.
891 *) mod_cache: Change the signature of the store_body() provider function
892 within the mod_cache provider interface to support an "in" brigade
893 and an "out" brigade instead of just a single input brigade. This
894 gives a cache provider the option to consume only part of the brigade
895 passed to it, rather than the whole brigade as was required before.
896 This fixes an out of memory and a request timeout condition that would
897 occur when the original document was a large file. Introduce
898 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
899 the amount of data to attempt to cache at a time. [Graham Leggett]
901 *) core: Add ErrorLogFormat to allow configuring error log format, including
902 additional information that is logged once per connection or request. Add
903 error log IDs for connections and request to allow correlating error log
904 lines and the corresponding access log entry. [Stefan Fritsch]
906 *) core: Disable sendfile by default. [Stefan Fritsch]
908 *) mod_cache: Check the request to determine whether we are allowed
909 to return cached content at all, and respect a "Cache-Control:
910 no-cache" header from a client. Previously, "no-cache" would
911 behave like "max-age=0". [Graham Leggett]
913 *) mod_cache: Use a proper filter context to hold filter data instead
914 of misusing the per-request configuration. Fixes a segfault on trunk
915 when the normal handler is used. [Graham Leggett]
917 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
918 it is too long. PR 49388. [Stefan Fritsch]
