9 core: Fix handling of byte-range requests to use less memory, to avoid
10 denial of service. If the sum of all ranges in a request is larger than
11 the original file, ignore the ranges and send the complete file.
12 PR 51714. [Stefan Fritsch, Jim Jagielski, Ruediger Pluem, Eric Covener,
13 <lowprio20 gmail.com>]
15 *) core, unixd: Add -D DUMP_RUN_CFG option to dump some configuration items
16 from the parsed (or default) config. This is useful for init scripts that
17 need to setup temporary directories and permissions. [Stefan Fritsch]
19 *) core, mod_actions, mod_asis: Downgrade error log messages which accompany
20 a 404 request status from loglevel error to info. PR: 35768. [Stefan
23 *) core: Fix hook sorting with Perl modules. PR: 45076. [Torsten Foertsch
24 <torsten foertsch gmx net>]
26 *) core: Enforce LimitRequestFieldSize after multiple headers with the same
27 name have been merged. [Stefan Fritsch]
29 *) mod_ssl: If MaxMemFree is set, ask OpenSSL >= 1.0.0 to reduce memory
30 usage. PR 51618. [Cristian RodrÃguez <crrodriguez opensuse org>,
33 *) mod_ssl: At startup, when checking a server certificate whether it
34 matches the configured ServerName, also take dNSName entries in the
35 subjectAltName extension into account. PR 32652, PR 47051. [Kaspar Brand]
37 *) mod_substitute: Reduce memory usage and copying of data. PR 50559.
40 *) mod_ssl/proxy: enable the SNI extension for backend TLS connections

44 situations and use them in many places. PR 51568, PR 51569, PR 51571.
47 *) Fix cross-compilation of mod_cgi/mod_cgid when APR_HAVE_STRUCT_RLIMIT is
48 false but RLIMIT_* are defined. PR51371. [Eric Covener]

60 the number of overlapping and reversing ranges (respectively) permitted
61 before returning the entire resource, with a default limit of 20.
64 *) mod_ldap: Optional function uldap_ssl_supported(r) always returned false
65 if called from a virtual host with mod_ldap directives in it. Did not
66 affect mod_authnz_ldap's usage of mod_ldap. [Eric Covener]
68 *) mod_filter: Instead of dropping the Accept-Ranges header when a filter
69 registered with AP_FILTER_PROTO_NO_BYTERANGE is present,
70 set the header value to "none". [Eric Covener, Ruediger Pluem]
72 *) core: Allow MaxRanges none|unlimited|default and set 'Accept-Ranges: none'
73 in the case Ranges are being ignored with MaxRanges none.
76 *) mod_ssl: revamp CRL-based revocation checking when validating
77 certificates of clients or proxied servers. Completely delegate
78 CRL processing to OpenSSL, and add a new [Proxy]CARevocationCheck
79 directive for controlling the revocation checking mode. [Kaspar Brand]
81 *) core: Add MaxRanges directive to control the number of ranges permitted
82 before returning the entire resource, with a default limit of 200.
85 *) mod_cache: Ensure that CacheDisable can correctly appear within
86 a LocationMatch. [Graham Leggett]
88 *) mod_cache: Fix the moving of the CACHE filter, which erroneously
89 stood down if the original filter was not added by configuration.
92 *) mod_ssl: improve certificate error logging. PR 47408. [Kaspar Brand]

100 *) core: Add API for resizable buffers. [Stefan Fritsch]
102 *) mod_ldap: Enable LDAPConnectionTimeout for LDAP toolkits that have
103 LDAP_OPT_CONNECT_TIMEOUT instead of LDAP_OPT_NETWORK_TIMEOUT, such
104 as Tivoli Directory Server 6.3 and later. [Eric Covener]
106 *) mod_ldap: Change default number of retries from 10 to 3, and add
107 an LDAPRetries and LDAPRetryDelay directives. [Eric Covener]
109 *) mod_authnz_ldap: Don't retry during authentication, because this just
110 multiplies the ample retries already being done by mod_ldap. [Eric Covener]
112 *) configure: Allow to explicitly disable modules even with module selection
113 'reallyall'. [Stefan Fritsch]
115 *) mod_rewrite: Check validity of each internal (int:) RewriteMap even if the
116 RewriteEngine is disabled in server context, avoiding a crash while
117 referencing the invalid int: map at runtime. PR 50994.
118 [Ben Noordhuis <info noordhuis nl>]
120 *) mod_ssl, configure: require OpenSSL 0.9.7 or later. [Kaspar Brand]

124 *) mod_ssl, configure, ab: drop support for RSA BSAFE SSL-C toolkit.
127 *) mod_usertrack: Run mod_usertrack earlier in the fixups hook to ensure the
128 cookie is set when modules such as mod_rewrite trigger a redirect. Also
129 use r->err_headers_out for the cookie, for the same reason. PR29755.
130 [Sami J. Mäkinen <sjm almamedia fi>, Eric Covener]
132 *) mod_proxy_http, mod_proxy_connect: Add 'proxy-status' and
133 'proxy-source-port' request notes for logging. PR 30195. [Stefan Fritsch]
135 *) configure: Enable ldap modules in 'all' and 'most' selections if ldap
136 is compiled into apr-util. [Stefan Fritsch]
138 *) core: Add ap_check_cmd_context()-check if a command is executed in
139 .htaccess file. [Stefan Fritsch]
141 *) mod_deflate: Fix endless loop if first bucket is metadata. PR 51590.
142 [Torsten Foertsch <torsten foertsch gmx net>]
144 *) mod_authn_socache: Fix to work in .htaccess if not configured anywhere
145 in httpd.conf, and introduce an AuthnCacheEnable directive.
148 Changes with Apache 2.3.14
150 *) mod_proxy_ajp: Improve trace logging. [Rainer Jung]
152 *) mod_proxy_ajp: Respect "reuse" flag in END_REPONSE packets.

156 e.g. to reverse proxy "Location: https://other-internal-server/login"
159 *) prefork, worker, event: Make sure crashes are logged to the error log if
160 httpd has already detached from the console. [Stefan Fritsch]
162 *) prefork, worker, event: Reduce period during startup/restart where a
163 successive signal may be lost. PR 43696. [Arun Bhalla <arun shme net>]
165 *) mod_allowmethods: Correct Merging of "reset" and do not allow an
166 empty parameter list for the AllowMethods directive. [Rainer Jung]
168 *) configure: Update selection of modules for 'all' and 'most'. 'all' will
169 now enable all modules except for example and test modules. Make the
170 selection for 'most' more useful (including ssl and proxy). Both 'all'
171 and 'most' will now disable modules if dependencies are missing instead
172 of aborting. If a specific module is requested with --enable-XXX=yes,
173 missing dependencies will still cause configure to exit with an error.
176 *) mod_ldap: Revert the integration of apr-ldap as ap_ldap which was done
177 in 2.3.13. [Stefan Fritsch]
179 *) core: For '*' or '_default_' vhosts, use a wildcard address of any
180 address family, rather than IPv4 only. [Joe Orton]
182 *) core, mod_rewrite, mod_ssl, mod_nw_ssl: Make the SERVER_NAME variable

190 ap_scan_script_header_err*_ex functions that take a module index for
192 mod_cgi, mod_cgid, mod_proxy_fcgi, mod_proxy_scgi, mod_isapi: Use the
193 new functions in order to make logging configurable per-module.
196 *) mod_dir: Add DirectoryIndexRedirect to send an external redirect to
197 the proper index. [Eric Covener]
199 *) mod_deflate: Don't try to compress requests with a zero sized body.
200 PR 51350. [Stefan Fritsch]
202 *) core: Fix startup on IP6-only systems. PR 50592. [Joe Orton,

207 whitelist in suexec. PR 51499. [Graham Laverty <graham reg ca>,
210 *) mod_rewrite: Fix regexp RewriteCond with NoCase. [Stefan Fritsch]
212 *) mod_log_debug: New module that allows to log custom messages at various
213 phases in the request processing. [Stefan Fritsch]
215 *) mod_ssl: Add some debug logging when loading server certificates.
216 PR 37912. [Nick Burch <nick burch alfresco com>]
218 *) configure: Support reallyall option also for --enable-mods-static.
221 *) mod_socache_dc: add --with-distcache to configure for choosing
222 the distcache installation directory. [Rainer Jung]
224 *) mod_socache_dc: use correct build variable MOD_SOCACHE_DC_LDADD
225 instead of MOD_SOCACHE_LDADD in build macro. [Rainer Jung]
227 *) mod_lua, mod_deflate: respect platform specific runpath linker
230 *) configure: Only link the httpd binary against PCRE. No other support
231 binary needs PCRE. [Rainer Jung]
233 *) configure: tolerate dependency checking failures for modules if
234 they have been enabled implicitely. [Rainer Jung]
236 *) configure: Allow to specify module specific custom linker flags via
237 the MOD_XXX_LDADD variables. [Rainer Jung]
239 Changes with Apache 2.3.13
241 *) ab: Support specifying the local address to use. PR 48930.
242 [Peter Schuller <scode spotify com>]
244 *) core: Add support to ErrorLogFormat for logging the system unique
245 thread id under Linux. [Stefan Fritsch]
247 *) event: New AsyncRequestWorkerFactor directive to influence how many
248 connections will be accepted per process. [Stefan Fritsch]
250 *) prefork, worker, event: Rename MaxClients to MaxRequestWorkers which
251 describes more accurately what it does. [Stefan Fritsch]
253 *) rotatelogs: Add -p argument to specify custom program to invoke
254 after a log rotation. PR 51285. [Sven Ulland <sveniu ifi.uio.no>,
257 *) mod_ssl: Don't do OCSP checks for valid self-issued certs. [Kaspar Brand]
259 *) mod_ssl: Avoid unnecessary renegotiations with SSLVerifyDepth 0.
260 PR 48215. [Kaspar Brand]
262 *) mod_status: Display information about asynchronous connections in the
263 server-status. PR 44377. [Stefan Fritsch]
265 *) mpm_event: If the number of connections of a process is very high, or if
266 all workers are busy, don't accept new connections in that process.
269 *) mpm_event: Process lingering close asynchronously instead of tying up
270 worker threads. [Jeff Trawick, Stefan Fritsch]
272 *) mpm_event: If MaxMemFree is set, limit the number of pools that is kept
273 around. [Stefan Fritsch]
275 *) mpm_event: Fix graceful restart aborting connections. PR 43359.
276 [Takashi Sato <takashi lans-tv com>]
278 *) mod_ssl: Disable AECDH ciphers in example config. PR 51363.
279 [Rob Stradling <rob comodo com>]
281 *) core: Introduce new function ap_get_conn_socket() to access the socket of
282 a connection. [Stefan Fritsch]
284 *) mod_data: Introduce a filter to support RFC2397 data URLs. [Graham

288 CONTEXT_DOCUMENT_ROOT, CONTEXT_PREFIX. PR 26052. PR 46198.
291 *) core: Allow to override document_root on a per-request basis. Introduce
292 new context_document_root and context_prefix which provide information
293 about non-global URI-to-directory mappings (from e.g. mod_userdir or
294 mod_alias) to scripts. PR 49705. [Stefan Fritsch]
296 *) core: Add <ElseIf> and <Else> to complement <If> sections.
299 *) mod_ext_filter: Remove DebugLevel option in favor of per-module loglevel.
302 *) mod_include: Make the "#if expr" element use the new "ap_expr" expression
303 parser. The old parser can still be used by setting the new directive
304 SSILegacyExprParser. [Stefan Fritsch]
306 *) core: Add some features to ap_expr for use by mod_include: a restricted
307 mode that does not allow to bypass request access restrictions; new
308 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an
309 alias for -U; an additional data entry in ap_expr_eval_ctx_t for use by
310 the consumer; an extensible ap_expr_exec_ctx() API that allows to use that
311 data entry. [Stefan Fritsch]
313 *) mod_include: Merge directory configs instead of one SSI* config directive
314 causing all other per-directory SSI* config directives to be reset.
317 *) mod_charset_lite: Remove DebugLevel option in favour of per-module
318 loglevel. [Stefan Fritsch]
320 *) core: Add ap_regexec_len() function that works with non-null-terminated
321 strings. PR 51231. [Yehezkel Horowitz <horowity checkpoint com>]
323 *) mod_authnz_ldap: If the LDAP server returns constraint violation,
324 don't treat this as an error but as "auth denied". [Stefan Fritsch]
326 *) mod_proxy_fcgi|scgi: Add support for "best guess" of PATH_INFO
327 for SCGI/FCGI. PR 50880, 50851. [Mark Montague <mark catseye.org>,
330 *) mod_cache: When content is served stale, and there is no means to
331 revalidate the content using ETag or Last-Modified, and we have
332 mandated no stale-on-error behaviour, stand down and don't cache.
333 Saves a cache write that will never be read.
336 *) mod_reqtimeout: Fix a timed out connection going into the keep-alive
337 state after a timeout when discarding a request body. PR 51103.
340 *) core: Add various file existance test operators to ap_expr.

356 *) mod_authnz_ldap: Resolve crash when LDAP is used for authorization only
357 [Scott Hill <shill genscape.com>]
359 *) support: Make sure check_forensic works with mod_unique_id loaded
362 *) Add child_status hook for tracking creation/termination of MPM child
363 processes. Add end_generation hook for notification when the last
364 MPM child of a generation exits. [Jeff Trawick]
366 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
367 process as opposed to disabling caching completely. This allows to use
368 the non-shared-memory cache as a workaround for the shared memory cache
369 not being available during graceful restarts. PR 48958. [Stefan Fritsch]
371 *) Add new ap_reserve_module_slots/ap_reserve_module_slots_directive API,
372 necessary if a module (like mod_perl) registers additional modules late
373 in the startup phase. [Stefan Fritsch]
375 *) core: Prevent segfault if DYNAMIC_MODULE_LIMIT is reached. PR 51072.
376 [Torsten Förtsch <torsten foertsch gmx net>]
378 *) WinNT MPM: Improve robustness under heavy load. [Jeff Trawick]
380 *) MinGW build improvements. PR 49535. [John Vandenberg

383 *) core: Support module names with colons in loglevel configuration.
384 [Torsten Förtsch <torsten foertsch gmx net>]
386 *) mod_ssl, ab: Support OpenSSL compiled without SSLv2 support.
389 *) core: Abort if the MPM is changed across restart. [Jeff Trawick]
391 *) mod_proxy_ajp: Add support for 'ProxyErrorOverride on'. PR 50945.
392 [Peter Pramberger <peter pramberger.at>, Jim Jagielski]
394 *) mod_proxy_fcgi: Add support for 'ProxyErrorOverride on'. PR 50913.
395 [Mark Montague <mark catseye.org>, Jim Jagielski]
397 *) core: Change the APIs of ap_cfg_getline() and ap_cfg_getc() to return an
398 error code. Abort with a nice error message if a config line is too long.
399 Partial fix for PR 50824. [Stefan Fritsch]
401 *) mod_info: Dump config to stdout during startup if -DDUMP_CONFIG is
402 specified. PR 31956. [Stefan Fritsch]
404 *) Restore visibility of DEFAULT_PIDLOG to core and modules. MPM
405 helper function ap_remove_pid() added. [Jeff Trawick]

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

469 the Expires is in the past, not as if the Expires is missing. PR 16521.
470 [Co-Advisor <coad@measurement-factory.com>]
472 *) mod_cache: We must ignore quoted-string values that appear in a
473 Cache-Control header. PR 50199. [Graham Leggett]
475 *) mod_dav: Revert change to send 501 error if unknown Content-* header is
476 received for a PUT request. PR 42978. [Stefan Fritsch]
478 *) mod_cache: Respect s-maxage as described by RFC2616 14.9.3, which must
479 take precedence if present. PR 35247. [Graham Leggett]
481 *) mod_ssl: Fix a possible startup failure if multiple SSL vhosts
482 are configured with the same ServerName and private key file.
483 [Masahiro Matsuya <mmatsuya redhat.com>, Joe Orton]
485 *) mod_socache_dc: Make module compile by fixing some typos.
486 PR 50735 [Mark Montague <mark catseye.org>]
488 *) prefork: Update MPM state in children during a graceful stop or
489 restart. PR 41743. [Andrew Punch <andrew.punch 247realmedia.com>]
491 *) mod_mime: Ignore leading dots when looking for mime extensions.
492 PR 50434 [Stefan Fritsch]
494 *) core: Add support to set variables with the 'Define' directive. The
495 variables that can then be used in the config using the ${VAR} syntax
496 known from envvar interpolation. [Stefan Fritsch]
498 *) mod_proxy_http: make adding of X-Forwarded-* headers configurable.
499 ProxyAddHeaders defaults to On. [Vincent Deffontaines]
501 *) mod_slotmem_shm: Increase memory alignment for slotmem data.
504 *) mod_ssl: Add config options for OCSP: SSLOCSPResponderTimeout,
505 SSLOCSPResponseMaxAge, SSLOCSPResponseTimeSkew.
506 [Kaspar Brand <httpd-dev.2011 velox.ch>]
508 *) mod_ssl: Revamp output buffering to reduce network overhead for
509 output fragmented into many buckets, such as chunked HTTP responses.
512 *) core: Apply <If> sections to all requests, not only to file base requests.
513 Allow to use <If> inside <Directory>, <Location>, and <Files> sections.
514 The merging of <If> sections now happens after the merging of <Location>
515 sections, even if an <If> section is embedded inside a <Directory> or
516 <Files> section. [Stefan Fritsch]
518 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
519 and using slotmem. Create foundation for dynamic growth/changes of
520 members within a balancer. Remove BalancerNonce in favor of a
521 per-balancer 'nonce' parameter. [Jim Jagielski]
523 *) mod_status: Don't show slots which are disabled by MaxClients as open.
524 PR: 47022 [Jordi Prats <jordi prats gmail com>, Stefan Fritsch]
526 *) mpm_prefork: Fix ap_mpm_query results for AP_MPMQ_MAX_DAEMONS and
529 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
530 authorization directives were mixed. [Stefan Fritsch]
532 *) mod_authn_socache: change directive name from AuthnCacheProvider
533 to AuthnCacheProvideFor. The term "provider" is overloaded in
534 this module, and we should avoid confusion between the provider
535 of a backend (AuthnCacheSOCache) and the authn provider(s) for
536 which this module provides cacheing (AuthnCacheProvideFor).
539 *) mod_proxy_http: Allocate the fake backend request from a child pool
540 of the backend connection, instead of misusing the pool of the frontend
541 request. Fixes a thread safety issue where buckets set aside in the
542 backend connection leak into other threads, and then disappear when
543 the frontend request is cleaned up, in turn causing corrupted buckets
544 to make other threads spin. [Graham Leggett]
546 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
547 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
548 escape other special characters with backslashes. The old format can
549 still be used with the LegacyDNStringFormat argument to SSLOptions.
551 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
552 scripts and mod_rewrite. [Stefan Fritsch]
554 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in
555 RewriteCond. [Stefan Fritsch]
557 *) mod_rewrite: Allow to unset environment variables using E=!VAR.
558 PR 49512. [Mark Drayton <mark markdrayton info>, Stefan Fritsch]
560 *) mod_headers: Restore the 2.3.8 and earlier default for the first
561 argument of the Header directive ("onsuccess"). [Eric Covener]
563 *) core: Disallow the mixing of relative and absolute Options PR 33708.
564 [Sönke Tesch <st kino-fahrplan.de>]
566 *) core: When exporting request headers to HTTP_* environment variables,
567 drop variables whose names contain invalid characters. Describe in the
568 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
570 *) core: When selecting an IP-based virtual host, favor an exact match for
571 the port over a wildcard (or omitted) port instead of favoring the one
572 that came first in the configuration file. [Eric Covener]
574 *) core: Overlapping virtual host address/port combinations now implicitly
575 enable name-based virtual hosting for that address. The NameVirtualHost
576 directive has no effect, and _default_ is interpreted the same as "*".

777 *) mod_disk_cache: Change on-disk header file format to support the
778 link of the device/inode of the data file to the matching header
779 file, and to support the option of not writing a data file when
780 the data file is empty. [Graham Leggett]
782 *) core/mod_unique_id: Add generate_log_id hook to allow to use
783 the ID generated by mod_unique_id as error log ID for requests.

787 that we asked for to leak to the client should the 304 response be
788 uncacheable. PR45341 [Graham Leggett]

796 on the local host. PR 19938. [Stefan Fritsch]
798 *) Event MPM: Fix crash accessing pollset on worker thread when child
799 process is exiting. [Jeff Trawick]
801 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
802 pass the system library path (LD_LIBRARY_PATH or platform-specific
803 variables) along with the system PATH, by default. Both should be
804 overridden together as desired using PassEnv etc; see mod_env.
807 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
808 capture a stale backend response, perform If-Modified-Since requests
809 against the backend, and serving from the cache all 304 responses.
810 This restores pre-2.2.4 cache behavior. [William Rowe]
812 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
813 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
814 the ambiguity of the symlink test "-ltest", introduce -h or -L as
815 symlink test operators. [William Rowe]
817 *) mod_cache: Give the cache provider the opportunity to choose to cache
818 or not cache based on the buckets present in the brigade, such as the
819 presence of a FILE bucket.
822 *) mod_authz_core: Allow authz providers to check args while reading the
823 config and allow to cache parsed args. Move 'all' and 'env' authz
824 providers from mod_authz_host to mod_authz_core. Add 'method' authz
825 provider depending on the HTTP method. [Stefan Fritsch]
827 *) mod_include: Move the request_rec within mod_include to be
828 exposed within include_ctx_t. [Graham Leggett]
830 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
831 variable being echoed or set to be decoded and then encoded as separate
832 steps. PR47686 [Graham Leggett]
834 *) mod_cache: Add a discrete commit_entity() provider function within the
835 mod_cache provider interface which is called to indicate to the
836 provider that caching is complete, giving the provider the opportunity
837 to commit temporary files permanently to the cache in an atomic
838 fashion. Replace the inconsistent use of error cleanups with a formal
839 set of pool cleanups attached to a subpool, which is destroyed on error.
842 *) mod_cache: Change the signature of the store_body() provider function
843 within the mod_cache provider interface to support an "in" brigade
844 and an "out" brigade instead of just a single input brigade. This
845 gives a cache provider the option to consume only part of the brigade
846 passed to it, rather than the whole brigade as was required before.
847 This fixes an out of memory and a request timeout condition that would
848 occur when the original document was a large file. Introduce
849 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
850 the amount of data to attempt to cache at a time. [Graham Leggett]
852 *) core: Add ErrorLogFormat to allow configuring error log format, including
853 additional information that is logged once per connection or request. Add
854 error log IDs for connections and request to allow correlating error log
855 lines and the corresponding access log entry. [Stefan Fritsch]
857 *) core: Disable sendfile by default. [Stefan Fritsch]
859 *) mod_cache: Check the request to determine whether we are allowed
860 to return cached content at all, and respect a "Cache-Control:
861 no-cache" header from a client. Previously, "no-cache" would
862 behave like "max-age=0". [Graham Leggett]
864 *) mod_cache: Use a proper filter context to hold filter data instead
865 of misusing the per-request configuration. Fixes a segfault on trunk
866 when the normal handler is used. [Graham Leggett]

1676 failure, and offer configuration option either to abort or
1677 to remove the filter and continue.

1777 the buffer, not to the final brigade. [Graham Leggett]
1779 *) mod_buffer: Optimise the buffering of heap buckets when the heap

1851 null value. [David Shane Holden <dpejesh apache.org>]
1853 *) core, authn/z: Determine registered authn/z providers directly in
1854 ap_setup_auth_internal(), which allows optional functions that just
1855 wrapped ap_list_provider_names() to be removed from authn/z modules.

1861 *) core: When testing for slash-terminated configuration paths in
1862 ap_location_walk(), don't look past the start of an empty string
1863 such as that created by a <Location ""> directive.
1866 *) core, mod_proxy: If a kept_body is present, it becomes safe for
1867 subrequests to support message bodies. Make sure that safety
1868 checks within the core and within the proxy are not triggered
1869 when kept_body is present. This makes it possible to embed
1870 proxied POST requests within mod_include. [Graham Leggett]
1872 *) mod_auth_form: Make sure the input filter stack is properly set
1873 up before reading the login form. Make sure the kept body filter
1874 is correctly inserted to ensure the body can be read a second
1875 time safely should the authn be successful. [Graham Leggett,
1878 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
1879 hook instead of during fixups. Add a safety check to ensure the
1880 filters cannot be inserted more than once. [Graham Leggett,
1883 *) ap_cache_cacheable_headers_out() will (now) always
1884 merge an error headers _before_ clearing them and _before_
1885 merging in the actual entity headers and doing normal
1886 hop-by-hop cleansing. [Dirk-Willem van Gulik].
1888 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
1889 for both in- and out-put headers; and replace it by a single
1890 ap_cache_cacheable_headers() wrapped in a in- and out-put
1891 specific ap_cache_cacheable_headers_in()/out(). The latter
1892 which will also merge error and ensure content-type. To keep
1893 cache modules consistent with ease. This API change bumps
1894 up the minor MM by one [Dirk-Willem van Gulik].
1896 *) Move the KeptBodySize directive, kept_body filters and the
1897 ap_parse_request_body function out of the http module and into a
1898 new module called mod_request, reducing the size of the core.
1901 *) mod_dbd: Handle integer configuration directive parameters with a

1909 in using an HTML form, storing the credentials within mod_session.
1912 *) Add a function to the http filters that is able to parse an HTML
1913 form request with the type of application/x-www-form-urlencoded.

1917 [Ruediger Pluem, Graham Leggett]
1919 *) mod_session_dbd: Add a session implementation capable of storing
1920 session information in a SQL database via the dbd interface. Useful
1921 for sites where session privacy is important. [Graham Leggett]
1923 *) mod_session_crypto: Add a session encoding implementation capable
1924 of encrypting and decrypting sessions wherever they may be stored.
1925 Introduces a level of privacy when sessions are stored on the
1926 browser. [Graham Leggett]
1928 *) mod_session_cookie: Add a session implementation capable of storing
1929 session information within cookies on the browser. Useful for high
1930 volume sites where server bound sessions are too resource intensive.
1933 *) mod_session: Add a generic session interface to unify the different
1934 attempts at saving persistent sessions across requests.
1937 *) core, authn/z: Avoid calling access control hooks for internal requests
1938 with configurations which match those of initial request. Revert to
1939 original behaviour (call access control hooks for internal requests
1940 with URIs different from initial request) if any access control hooks or
1941 providers are not registered as permitting this optimization.
1942 Introduce wrappers for access control hook and provider registration
1943 which can accept additional mode and flag data. [Chris Darroch]

2054 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
2056 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
2058 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets

2154 the freeing of its pool are now done when the EOR bucket is destroyed.
2155 This has the effect of delaying the logging until right after the last
