350 empty parameter list for the AllowMethods directive. [Rainer Jung]
352 *) configure: Update selection of modules for 'all' and 'most'. 'all' will

356 of aborting. If a specific module is requested with --enable-XXX=yes,
357 missing dependencies will still cause configure to exit with an error.

491 mode that does not allow to bypass request access restrictions; new
492 variables DOCUMENT_URI (alias for REQUEST_URI), LAST_MODIFIED; -A as an

712 *) mod_authn_socache: change directive name from AuthnCacheProvider
713 to AuthnCacheProvideFor. The term "provider" is overloaded in
714 this module, and we should avoid confusion between the provider
715 of a backend (AuthnCacheSOCache) and the authn provider(s) for
716 which this module provides cacheing (AuthnCacheProvideFor).
719 *) mod_proxy_http: Allocate the fake backend request from a child pool
720 of the backend connection, instead of misusing the pool of the frontend
721 request. Fixes a thread safety issue where buckets set aside in the
722 backend connection leak into other threads, and then disappear when
723 the frontend request is cleaned up, in turn causing corrupted buckets
724 to make other threads spin. [Graham Leggett]

754 *) core: Overlapping virtual host address/port combinations now implicitly
755 enable name-based virtual hosting for that address. The NameVirtualHost
756 directive has no effect, and _default_ is interpreted the same as "*".

828 expression. [Stefan Fritsch]
830 *) mod_proxy: Fix ProxyPassInterpolateEnv directive. PR 50292.
833 *) suEXEC: Add Suexec directive to disable suEXEC without renaming the

909 running out of space when many small files are cached.
912 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
913 describes more accurately what the directive does. The old name
914 still works but logs a warning. [Stefan Fritsch]
916 *) mod_cache: Optionally serve stale data when a revalidation returns a
917 5xx response, controlled by the CacheStaleOnError directive.
920 *) htcacheclean: Allow the listing of valid URLs within the cache, with
921 the option to list entry metadata such as sizes and times. [Graham
924 *) mod_cache: correctly parse quoted strings in cache headers.
927 *) mod_cache: Allow control over the base URL of reverse proxied requests
928 using the CacheKeyBaseURL directive, so that the cache key can be
929 calculated from the endpoint URL instead of the server URL. [Graham

945 *) htcacheclean: Allow the option to round up file sizes to a given
946 block size, improving the accuracy of disk usage. [Graham Leggett]
948 *) mod_ssl: Add authz providers for use with mod_authz_core and its
949 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
950 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
951 'ssl-require' (expressions with same syntax as SSLRequire).
954 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
955 bison instead of yacc. [Stefan Fritsch]
957 *) mod_disk_cache: Change on-disk header file format to support the
958 link of the device/inode of the data file to the matching header
959 file, and to support the option of not writing a data file when
960 the data file is empty. [Graham Leggett]
962 *) core/mod_unique_id: Add generate_log_id hook to allow to use
963 the ID generated by mod_unique_id as error log ID for requests.
966 *) mod_cache: Make sure that we never allow a 304 Not Modified response
967 that we asked for to leak to the client should the 304 response be
968 uncacheable. PR45341 [Graham Leggett]
970 *) mod_cache: Add the cache_status hook to register the final cache
971 decision hit/miss/revalidate. Add optional support for an X-Cache
972 and/or an X-Cache-Detail header to add the cache status to the
973 response. PR48241 [Graham Leggett]
975 *) mod_authz_host: Add 'local' provider that matches connections originating
976 on the local host. PR 19938. [Stefan Fritsch]
978 *) Event MPM: Fix crash accessing pollset on worker thread when child
979 process is exiting. [Jeff Trawick]
981 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
982 pass the system library path (LD_LIBRARY_PATH or platform-specific
983 variables) along with the system PATH, by default. Both should be
984 overridden together as desired using PassEnv etc; see mod_env.
987 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
988 capture a stale backend response, perform If-Modified-Since requests
989 against the backend, and serving from the cache all 304 responses.
990 This restores pre-2.2.4 cache behavior. [William Rowe]
992 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
993 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
994 the ambiguity of the symlink test "-ltest", introduce -h or -L as
995 symlink test operators. [William Rowe]
997 *) mod_cache: Give the cache provider the opportunity to choose to cache
998 or not cache based on the buckets present in the brigade, such as the
999 presence of a FILE bucket.
1002 *) mod_authz_core: Allow authz providers to check args while reading the
1003 config and allow to cache parsed args. Move 'all' and 'env' authz
1004 providers from mod_authz_host to mod_authz_core. Add 'method' authz
1005 provider depending on the HTTP method. [Stefan Fritsch]
1007 *) mod_include: Move the request_rec within mod_include to be
1008 exposed within include_ctx_t. [Graham Leggett]
1010 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
1011 variable being echoed or set to be decoded and then encoded as separate
1012 steps. PR47686 [Graham Leggett]
1014 *) mod_cache: Add a discrete commit_entity() provider function within the
1015 mod_cache provider interface which is called to indicate to the
1016 provider that caching is complete, giving the provider the opportunity
1017 to commit temporary files permanently to the cache in an atomic
1018 fashion. Replace the inconsistent use of error cleanups with a formal
1019 set of pool cleanups attached to a subpool, which is destroyed on error.
1022 *) mod_cache: Change the signature of the store_body() provider function
1023 within the mod_cache provider interface to support an "in" brigade
1024 and an "out" brigade instead of just a single input brigade. This
1025 gives a cache provider the option to consume only part of the brigade
1026 passed to it, rather than the whole brigade as was required before.
1027 This fixes an out of memory and a request timeout condition that would
1028 occur when the original document was a large file. Introduce
1029 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
1030 the amount of data to attempt to cache at a time. [Graham Leggett]
1032 *) core: Add ErrorLogFormat to allow configuring error log format, including
1033 additional information that is logged once per connection or request. Add
1034 error log IDs for connections and request to allow correlating error log
1035 lines and the corresponding access log entry. [Stefan Fritsch]
1037 *) core: Disable sendfile by default. [Stefan Fritsch]
1039 *) mod_cache: Check the request to determine whether we are allowed
1040 to return cached content at all, and respect a "Cache-Control:
1041 no-cache" header from a client. Previously, "no-cache" would
1042 behave like "max-age=0". [Graham Leggett]
1044 *) mod_cache: Use a proper filter context to hold filter data instead
1045 of misusing the per-request configuration. Fixes a segfault on trunk
1046 when the normal handler is used. [Graham Leggett]

1155 mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
1156 attack when compiled against OpenSSL version 0.9.8m or later. Introduces
1157 the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
1158 and offer unsafe legacy renegotiation with clients which do not yet
1159 support the new secure renegotiation protocol, RFC 5746.
1160 [Joe Orton, and with thanks to the OpenSSL Team]
1162 *) SECURITY: CVE-2009-3555 (cve.mitre.org)
1163 mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
1164 by rejecting any client-initiated renegotiations. Forcibly disable
1165 keepalive for the connection if there is any buffered data readable. Any
1166 configuration which requires renegotiation for per-directory/location
1167 access control is still vulnerable, unless using OpenSSL >= 0.9.8l.

1170 *) SECURITY: CVE-2010-0408 (cve.mitre.org)
1171 mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
1172 when request headers indicate a request body is incoming; not a case of
1173 HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
1175 *) SECURITY: CVE-2010-0425 (cve.mitre.org)
1176 mod_isapi: Do not unload an isapi .dll module until the request
1177 processing is completed, avoiding orphaned callback pointers.
1178 [Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
1180 *) core: Filter init functions are now run strictly once per request
1181 before handler invocation. The init functions are no longer run
1182 for connection filters. PR 49328. [Joe Orton]
1184 *) core: Adjust the output filter chain correctly in an internal
1185 redirect from a subrequest, preserving filters from the main
1186 request as necessary. PR 17629. [Joe Orton]
1188 *) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
1189 Response if they so choose to do so. Previously an attempt to cache a 206
1190 was arbitrarily allowed if the response contained an Expires or
1191 Cache-Control header, and arbitrarily denied if both headers were missing.
1194 *) core: Add microsecond timestamp fractions, process id and thread id
1195 to the error log. [Rainer Jung]

1218 mod_ssl/mod_proxy*: Adjust loglevels to be less verbose at levels info
1220 mod_dumpio: Replace DumpIOLogLevel with trace log levels.
1223 *) mod_ldap: LDAP caching was suppressed (and ldap-status handler returns
1224 title page only) when any mod_ldap directives were used in VirtualHost
1225 context. [Eric Covener]
1227 *) mod_disk_cache: Decline the opportunity to cache if the response is
1228 a 206 Partial Content. This stops a reverse proxied partial response
1229 from becoming cached, and then being served in subsequent responses.
1232 *) mod_deflate: avoid the risk of forwarding data before headers are set.

1288 *) Introduce SSLFIPS directive to support OpenSSL FIPS_mode; permits all
1289 builds of mod_ssl to use 'SSLFIPS off' for portability, but the proper

1320 *) mod_ldap: LDAPTrustedClientCert now accepts CA_DER/CA_BASE64 argument
1321 types previously allowed only in LDAPTrustedGlobalCert. [Eric Covener]
1323 *) mod_negotiation: Preserve query string over multiviews negotiation.

1352 request bodies back within the response through the output filter
1353 stack. Can be used to turn an output filter into a web service.
1356 *) mod_proxy_http: Make sure that when an ErrorDocument is served
1357 from a reverse proxied URL, that the subrequest respects the status
1358 of the original request. This brings the behaviour of proxy_handler
1359 in line with default_handler. PR 47106. [Graham Leggett]

1384 responses if desired. Fix the default value of the SSIAccessEnable
1385 directive. [Graham Leggett]
1387 *) Add new UnDefine directive to undefine a variable. PR 35350.

2229 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
2231 *) mod_dbd: Key the storage of prepared statements on the hex string
2232 value of server_rec, rather than the server name, as the server name
2233 may change (eg when the server name is set) at any time, causing
2234 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
2236 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
2238 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
2239 the first bucket from the brigade, finds it not to be a FILE
2240 bucket and barfs. The fix is to pass a bucket rather than a brigade.
2241 [Niklas Edmundsson <nikke acc.umu.se>]
2243 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
2245 *) ap_get_server_version() has been removed. Third-party modules must
2246 now use ap_get_server_banner() or ap_get_server_description().
2249 *) All MPMs: Introduce a check_config phase between pre_config and
2250 open_logs, to allow modules to review interdependent configuration
2251 directive values and adjust them while messages can still be logged
2252 to the console. Handle relevant MPM directives during this phase
2253 and format messages for both the console and the error log, as
2254 appropriate. [Chris Darroch]
2256 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
2257 to circumvent the symbolic link checks imposed by FollowSymLinks and
2258 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
2260 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
2261 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
2262 The default is none as this is far greater debugging resolution than
2263 the typical administrator is prepared to untangle. [William Rowe]
2265 *) mod_disk_cache: If possible, check if the size of an object to cache is
2266 within the configured boundaries before actually saving data.
2267 [Niklas Edmundsson <nikke acc.umu.se>]
2269 *) Worker and event MPMs: Remove improper scoreboard updates which were
2270 performed in the event of a fork() failure. [Chris Darroch]
2272 *) Add support for fcgi:// proxies to mod_rewrite.
2273 [Markus Schiegl <ms schiegl.com>]
2275 *) Remove incorrect comments from scoreboard.h regarding conditional
2276 loading of worker_score structure with mod_status, and remove unused
2277 definitions relating to old life_status field.
2278 [Chris Darroch <chrisd pearsoncmg.com>]
2280 *) Remove allocation of memory for unused array of lb_score pointers
2281 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
2283 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
2284 [Garrett Rooney, Jim Jagielski, Paul Querna]
2286 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
2287 [Chris Darroch <chrisd pearsoncmg.com>]
2289 *) mod_charset_lite: Remove Content-Length when output filter can
2290 invalidate it. Warn when input filter can invalidate it.
2293 *) Authz: Add the new module mod_authn_core that will provide common
2294 authn directives such as 'AuthType', 'AuthName'. Move the directives
2295 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
2296 into mod_authn_core. [Brad Nicholes]
2298 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
2299 into the new module mod_access_compat which can be loaded to provide
2300 support for these directives.
2303 *) Authz: Move the 'Require' directive from the core module as well as
2304 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
2305 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
2306 logic into the authorization processing. [Brad Nicholes]
2308 *) Authz: Add the new module mod_authz_core which acts as the
2309 authorization provider vector and contains common authz
2310 directives. [Brad Nicholes]
2312 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
2313 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
2315 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
2316 host-based access control provided by mod_authz_host and invoked
2317 through the 'Require' directive. [Brad Nicholes]
2319 *) Authz: Convert all of the authz modules from hook based to
2320 provider based. [Brad Nicholes]
2322 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
2323 seconds to cache a document.
2324 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
2326 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
2328 *) Fix typo in ProxyStatus syntax error message.
2329 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
2331 *) Asynchronous write completion for the Event MPM. [Brian Pane]
2333 *) Added an End-Of-Request bucket type. The logging of a request and
2334 the freeing of its pool are now done when the EOR bucket is destroyed.
2335 This has the effect of delaying the logging until right after the last
2336 of the response is sent; ap_core_output_filter() calls the access logger
2337 indirectly when it destroys the EOR bucket. [Brian Pane]
2339 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
2340 and the format of statistical output has changed. [Colm MacCarthaigh]
2342 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
2344 *) Added new connection states for handler and write completion
2347 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
2350 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
2351 allowing string-valued client certificate attributes to be used for
2352 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
