82 *) mod_filter: Instead of dropping the Accept-Ranges header when a filter
83 registered with AP_FILTER_PROTO_NO_BYTERANGE is present,
84 set the header value to "none". [Eric Covener, Ruediger Pluem]

87 in the case Ranges are being ignored with MaxRanges none.
90 *) mod_ssl: revamp CRL-based revocation checking when validating
91 certificates of clients or proxied servers. Completely delegate
92 CRL processing to OpenSSL, and add a new [Proxy]CARevocationCheck

179 *) mod_allowmethods: Correct Merging of "reset" and do not allow an
180 empty parameter list for the AllowMethods directive. [Rainer Jung]
182 *) configure: Update selection of modules for 'all' and 'most'. 'all' will
183 now enable all modules except for example and test modules. Make the
184 selection for 'most' more useful (including ssl and proxy). Both 'all'
185 and 'most' will now disable modules if dependencies are missing instead
186 of aborting. If a specific module is requested with --enable-XXX=yes,
187 missing dependencies will still cause configure to exit with an error.
190 *) mod_ldap: Revert the integration of apr-ldap as ap_ldap which was done
191 in 2.3.13. [Stefan Fritsch]

204 ap_scan_script_header_err*_ex functions that take a module index for
206 mod_cgi, mod_cgid, mod_proxy_fcgi, mod_proxy_scgi, mod_isapi: Use the
207 new functions in order to make logging configurable per-module.
210 *) mod_dir: Add DirectoryIndexRedirect to send an external redirect to

232 *) configure: Support reallyall option also for --enable-mods-static.
235 *) mod_socache_dc: add --with-distcache to configure for choosing
236 the distcache installation directory. [Rainer Jung]
238 *) mod_socache_dc: use correct build variable MOD_SOCACHE_DC_LDADD
239 instead of MOD_SOCACHE_LDADD in build macro. [Rainer Jung]
241 *) mod_lua, mod_deflate: respect platform specific runpath linker
244 *) configure: Only link the httpd binary against PCRE. No other support
245 binary needs PCRE. [Rainer Jung]
247 *) configure: tolerate dependency checking failures for modules if
248 they have been enabled implicitely. [Rainer Jung]
250 *) configure: Allow to specify module specific custom linker flags via
251 the MOD_XXX_LDADD variables. [Rainer Jung]
253 Changes with Apache 2.3.13
255 *) ab: Support specifying the local address to use. PR 48930.

262 connections will be accepted per process. [Stefan Fritsch]
264 *) prefork, worker, event: Rename MaxClients to MaxRequestWorkers which
265 describes more accurately what it does. [Stefan Fritsch]
267 *) rotatelogs: Add -p argument to specify custom program to invoke
268 after a log rotation. PR 51285. [Sven Ulland <sveniu ifi.uio.no>,
271 *) mod_ssl: Don't do OCSP checks for valid self-issued certs. [Kaspar Brand]

274 PR 48215. [Kaspar Brand]
276 *) mod_status: Display information about asynchronous connections in the
277 server-status. PR 44377. [Stefan Fritsch]
279 *) mpm_event: If the number of connections of a process is very high, or if
280 all workers are busy, don't accept new connections in that process.
283 *) mpm_event: Process lingering close asynchronously instead of tying up
284 worker threads. [Jeff Trawick, Stefan Fritsch]
286 *) mpm_event: If MaxMemFree is set, limit the number of pools that is kept
287 around. [Stefan Fritsch]
289 *) mpm_event: Fix graceful restart aborting connections. PR 43359.
290 [Takashi Sato <takashi lans-tv com>]

317 parser. The old parser can still be used by setting the new directive
318 SSILegacyExprParser. [Stefan Fritsch]
320 *) core: Add some features to ap_expr for use by mod_include: a restricted
321 mode that does not allow to bypass request access restrictions; new
322 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
323 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
324 the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
325 data entry. [Stefan Fritsch]
327 *) mod_include: Merge directory configs instead of one SSI* config directive
328 causing all other per-directory SSI* config directives to be reset.
331 *) mod_charset_lite: Remove DebugLevel option in favour of per-module
332 loglevel. [Stefan Fritsch]
334 *) core: Add ap_regexec_len() function that works with non-null-terminated
335 strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]
337 *) mod_authnz_ldap: If the LDAP server returns constraint violation,
338 don't treat this as an error but as "auth denied". [Stefan Fritsch]
340 *) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO
341 for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
344 *) mod_cache: When content is served stale, and there is no means to
345 revalidate the content using ETag or Last-Modified, and we have
346 mandated no stale-on-error behaviour, stand down and don't cache.
347 Saves a cache write that will never be read.
350 *) mod_reqtimeout: Fix a timed out connection going into the keep-alive
351 state after a timeout when discarding a request body. PR 51103.
354 *) core: Add various file existance test operators to ap_expr.

377 processes. Add end_generation hook for notification when the last
378 MPM child of a generation exits. [Jeff Trawick]
380 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
381 process as opposed to disabling caching completely. This allows to use
382 the non-shared-memory cache as a workaround for the shared memory cache
383 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
385 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
386 necessary if a module (like mod_perl) registers additional modules late
387 in the startup phase. [Stefan Fritsch]
389 *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.

409 [Mark Montague <mark catseye.org>, Jim Jagielski]
411 *) core: Change the APIs of ap_cfg_getline() and ap_cfg_getc() to return an
412 error code. Abort with a nice error message if a config line is too long.
413 Partial fix for PR 50824. [Stefan Fritsch]
415 *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
416 specified. PR 31956. [Stefan Fritsch]
418 *) Restore visibility of DEFAULT_PIDLOG to core and modules. MPM
419 helper function ap_remove_pid() added. [Jeff Trawick]

438 of bound backend LDAP connections. PR47634 [Eric Covener]
440 *) mod_cache: Make CacheEnable and CacheDisable configurable per
441 directory in addition to per server, making them work from within
442 a LocationMatch. [Graham Leggett]
444 *) worker, event, prefork: Correct several issues when built as
445 DSOs; most notably, the scoreboard was reinitialized during graceful
446 restart, such that processes of the previous generation were not
447 observable. [Jeff Trawick]
449 Changes with Apache 2.3.11
451 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
452 Win32's cscript interpreter can only use a single quote as comment char.
455 *) mod_proxy: balancer-manager now uses POST instead of GET.
458 *) core: new util function: ap_parse_form_data(). Previously,
459 this capability was tucked away in mod_request. [Jim Jagielski]
461 *) core: new hook: ap_run_pre_read_request. [Jim Jagielski]
463 *) mod_cache: When a request other than GET or HEAD arrives, we must
464 invalidate existing cache entities as per RFC2616 13.10. PR 15868.
467 *) modules: Fix many modules that were not correctly initializing if they
468 were not active during server startup but got enabled later during a
469 graceful restart. [Stefan Fritsch]
471 *) core: Create new ap_state_query function that allows modules to determine
472 if the current configuration run is the initial one at server startup,
473 and if the server is started for testing/config dumping only.
476 *) mod_proxy: Runtime configuration of many parameters for existing
477 balancers via the balancer-manager. [Jim Jagielski]
479 *) mod_proxy: Runtime addition of new workers (BalancerMember) for existing

484 [Co-Advisor <coad@measurement-factory.com>]
486 *) mod_cache: We must ignore quoted-string values that appear in a
487 Cache-Control header. PR 50199. [Graham Leggett]

493 take precedence if present. PR 35247. [Graham Leggett]
495 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
496 are configured with the same ServerName and private key file.
497 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]
499 *) mod_socache_dc: Make module compile by fixing some typos.

503 restart. PR 41743. [Andrew Punch <andrew.punch 247realmedia.com>]
505 *) mod_mime: Ignore leading dots when looking for mime extensions.
506 PR 50434 [Stefan Fritsch]
508 *) core: Add support to set variables with the 'Define' directive. The
509 variables that can then be used in the config using the ${VAR} syntax

522 *) mod_ssl: Revamp output buffering to reduce network overhead for
523 output fragmented into many buckets, such as chunked HTTP responses.
526 *) core: Apply <If> sections to all requests, not only to file base requests.
527 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
528 The merging of <If> sections now happens after the merging of <Location>
529 sections, even if an <If> section is embedded inside a <Directory> or
530 <Files> section. [Stefan Fritsch]
532 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
533 and using slotmem. Create foundation for dynamic growth/changes of
534 members within a balancer. Remove BalancerNonce in favor of a
535 per-balancer 'nonce' parameter. [Jim Jagielski]

544 authorization directives were mixed. [Stefan Fritsch]
546 *) mod_authn_socache: change directive name from AuthnCacheProvider
547 to AuthnCacheProvideFor. The term "provider" is overloaded in
548 this module, and we should avoid confusion between the provider
549 of a backend (AuthnCacheSOCache) and the authn provider(s) for
550 which this module provides cacheing (AuthnCacheProvideFor).
553 *) mod_proxy_http: Allocate the fake backend request from a child pool
554 of the backend connection, instead of misusing the pool of the frontend
555 request. Fixes a thread safety issue where buckets set aside in the
556 backend connection leak into other threads, and then disappear when
557 the frontend request is cleaned up, in turn causing corrupted buckets
558 to make other threads spin. [Graham Leggett]
560 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
561 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
562 escape other special characters with backslashes. The old format can
563 still be used with the LegacyDNStringFormat argument to SSLOptions.
565 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
566 scripts and mod_rewrite. [Stefan Fritsch]
568 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in

822 capture a stale backend response, perform If-Modified-Since requests
823 against the backend, and serving from the cache all 304 responses.
824 This restores pre-2.2.4 cache behavior. [William Rowe]

848 *) mod_cache: Add a discrete commit_entity() provider function within the
849 mod_cache provider interface which is called to indicate to the
850 provider that caching is complete, giving the provider the opportunity
851 to commit temporary files permanently to the cache in an atomic
852 fashion. Replace the inconsistent use of error cleanups with a formal
853 set of pool cleanups attached to a subpool, which is destroyed on error.
856 *) mod_cache: Change the signature of the store_body() provider function
857 within the mod_cache provider interface to support an "in" brigade
858 and an "out" brigade instead of just a single input brigade. This
859 gives a cache provider the option to consume only part of the brigade
860 passed to it, rather than the whole brigade as was required before.
861 This fixes an out of memory and a request timeout condition that would
862 occur when the original document was a large file. Introduce
863 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
864 the amount of data to attempt to cache at a time. [Graham Leggett]

869 lines and the corresponding access log entry. [Stefan Fritsch]
871 *) core: Disable sendfile by default. [Stefan Fritsch]
873 *) mod_cache: Check the request to determine whether we are allowed
874 to return cached content at all, and respect a "Cache-Control:
875 no-cache" header from a client. Previously, "no-cache" would
876 behave like "max-age=0". [Graham Leggett]
878 *) mod_cache: Use a proper filter context to hold filter data instead
879 of misusing the per-request configuration. Fixes a segfault on trunk

1881 subrequests to support message bodies. Make sure that safety
1882 checks within the core and within the proxy are not triggered
1883 when kept_body is present. This makes it possible to embed
1884 proxied POST requests within mod_include. [Graham Leggett]
1886 *) mod_auth_form: Make sure the input filter stack is properly set
1887 up before reading the login form. Make sure the kept body filter
1888 is correctly inserted to ensure the body can be read a second
1889 time safely should the authn be successful. [Graham Leggett,
1892 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
1893 hook instead of during fixups. Add a safety check to ensure the
1894 filters cannot be inserted more than once. [Graham Leggett,

1904 ap_cache_cacheable_headers() wrapped in a in- and out-put
1905 specific ap_cache_cacheable_headers_in()/out(). The latter
1906 which will also merge error and ensure content-type. To keep
1907 cache modules consistent with ease. This API change bumps
1908 up the minor MM by one [Dirk-Willem van Gulik].
1910 *) Move the KeptBodySize directive, kept_body filters and the

1942 *) mod_session_cookie: Add a session implementation capable of storing
1943 session information within cookies on the browser. Useful for high
1944 volume sites where server bound sessions are too resource intensive.
1947 *) mod_session: Add a generic session interface to unify the different
1948 attempts at saving persistent sessions across requests.
1951 *) core, authn/z: Avoid calling access control hooks for internal requests
1952 with configurations which match those of initial request. Revert to
1953 original behaviour (call access control hooks for internal requests
1954 with URIs different from initial request) if any access control hooks or
1955 providers are not registered as permitting this optimization.
