1738 MPM child of a generation exits. [Jeff Trawick]
1740 *) mod_ldap: Make LDAPSharedCacheSize 0 create a non-shared-memory cache per
1741 process as opposed to disabling caching completely. This allows to use
1742 the non-shared-memory cache as a workaround for the shared memory cache
1743 not being available during graceful restarts. PR 48958. [Stefan Fritsch]

1806 restart, such that processes of the previous generation were not
1807 observable. [Jeff Trawick]
1809 Changes with Apache 2.3.11
1811 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.
1812 Win32's cscript interpreter can only use a single quote as comment char.
1815 *) mod_proxy: balancer-manager now uses POST instead of GET.

1824 were not active during server startup but got enabled later during a
1825 graceful restart. [Stefan Fritsch]
1827 *) core: Create new ap_state_query function that allows modules to determine
1828 if the current configuration run is the initial one at server startup,

1886 <Files> section. [Stefan Fritsch]
1888 *) mod_proxy: Refactor usage of shared data by dropping the scoreboard
1889 and using slotmem. Create foundation for dynamic growth/changes of
1890 members within a balancer. Remove BalancerNonce in favor of a
1891 per-balancer 'nonce' parameter. [Jim Jagielski]

1899 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
1900 authorization directives were mixed. [Stefan Fritsch]
1902 *) mod_authn_socache: change directive name from AuthnCacheProvider
1903 to AuthnCacheProvideFor. The term "provider" is overloaded in
1904 this module, and we should avoid confusion between the provider
1905 of a backend (AuthnCacheSOCache) and the authn provider(s) for
1906 which this module provides cacheing (AuthnCacheProvideFor).
1909 *) mod_proxy_http: Allocate the fake backend request from a child pool
1910 of the backend connection, instead of misusing the pool of the frontend
1911 request. Fixes a thread safety issue where buckets set aside in the
1912 backend connection leak into other threads, and then disappear when
1913 the frontend request is cleaned up, in turn causing corrupted buckets
1914 to make other threads spin. [Graham Leggett]
1916 *) mod_ssl: Change the format of the SSL_{CLIENT,SERVER}_{I,S}_DN variables
1917 to be RFC 2253 compatible, convert non-ASCII characters to UTF8, and
1918 escape other special characters with backslashes. The old format can
1919 still be used with the LegacyDNStringFormat argument to SSLOptions.
1921 *) core, mod_rewrite: Make the REQUEST_SCHEME variable available to
1922 scripts and mod_rewrite. [Stefan Fritsch]
1924 *) mod_rewrite: Allow to use arbitrary boolean expressions (ap_expr) in

1936 *) core: When exporting request headers to HTTP_* environment variables,
1937 drop variables whose names contain invalid characters. Describe in the
1938 docs how to restore the old behaviour. [Malte S. Stretz <mss apache org>]
1940 *) core: When selecting an IP-based virtual host, favor an exact match for
1941 the port over a wildcard (or omitted) port instead of favoring the one
1942 that came first in the configuration file. [Eric Covener]
1944 *) core: Overlapping virtual host address/port combinations now implicitly
1945 enable name-based virtual hosting for that address. The NameVirtualHost
1946 directive has no effect, and _default_ is interpreted the same as "*".
1949 *) core: In the absence of any Options directives, the default is now

2010 *) mod_include: Add the onerror attribute to the include element,
2011 allowing an URL to be specified to include on error. [Graham
2014 *) mod_cache_disk: mod_disk_cache renamed to mod_cache_disk, to be

2034 it was impossible to switch off. [Graham Leggett]
2036 *) core, mod_include, mod_ssl: Move the expression parser derived from
2037 mod_include back into mod_include. Replace ap_expr with a parser
2038 derived from mod_ssl's parser. Make mod_ssl use the new parser. Rework
2039 ap_expr's public interface and provide hooks for modules to add variables
2040 and functions. [Stefan Fritsch]
2042 *) core: Do the hook sorting earlier so that the hooks are properly sorted
2043 for the pre_config hook and during parsing the config. [Stefan Fritsch]
2045 *) core: In the absence of any AllowOverride directives, the default is now
2046 "None" instead of "All". PR49823 [Eric Covener]

2075 *) mod_proxy: Release the backend connection as soon as EOS is detected,
2076 so the backend isn't forced to wait for the client to eventually
2077 acknowledge the data. [Graham Leggett]
2079 *) mod_proxy: Optimise ProxyPass within a Location so that it is stored
2080 per-directory, and chosen during the location walk. Make ProxyPass

2083 *) core: Fix segfault if per-module LogLevel is on virtual host

2094 cert verification fails. PR 50093, PR 50094. [Lassi Tuura <lat cern ch>,
2097 *) htcacheclean: Teach htcacheclean to limit cache size by number of
2098 inodes in addition to size of files. Prevents a cache disk from
2099 running out of space when many small files are cached.
2102 *) core: Rename MaxRequestsPerChild to MaxConnectionsPerChild, which
2103 describes more accurately what the directive does. The old name
2104 still works but logs a warning. [Stefan Fritsch]
2106 *) mod_cache: Optionally serve stale data when a revalidation returns a
2107 5xx response, controlled by the CacheStaleOnError directive.
2110 *) htcacheclean: Allow the listing of valid URLs within the cache, with
2111 the option to list entry metadata such as sizes and times. [Graham
2114 *) mod_cache: correctly parse quoted strings in cache headers.
2117 *) mod_cache: Allow control over the base URL of reverse proxied requests
2118 using the CacheKeyBaseURL directive, so that the cache key can be
2119 calculated from the endpoint URL instead of the server URL. [Graham
2122 *) mod_cache: CacheLastModifiedFactor, CacheStoreNoStore, CacheStorePrivate,
2123 CacheStoreExpired, CacheIgnoreNoLastMod, CacheDefaultExpire,
2124 CacheMinExpire and CacheMaxExpire can be set per directory/location.
2127 *) mod_disk_cache: CacheMaxFileSize, CacheMinFileSize, CacheReadSize and

2135 *) htcacheclean: Allow the option to round up file sizes to a given
2136 block size, improving the accuracy of disk usage. [Graham Leggett]
2138 *) mod_ssl: Add authz providers for use with mod_authz_core and its
2139 RequireAny/RequireAll containers: 'ssl' (equivalent to SSLRequireSSL),
2140 'ssl-verify-client' (for use with 'SSLVerifyClient optional'), and
2141 'ssl-require' (expressions with same syntax as SSLRequire).
2144 *) mod_ssl: Make the ssl expression parser thread-safe. It now requires
2145 bison instead of yacc. [Stefan Fritsch]
2147 *) mod_disk_cache: Change on-disk header file format to support the
2148 link of the device/inode of the data file to the matching header
2149 file, and to support the option of not writing a data file when
2150 the data file is empty. [Graham Leggett]
2152 *) core/mod_unique_id: Add generate_log_id hook to allow to use
2153 the ID generated by mod_unique_id as error log ID for requests.
2156 *) mod_cache: Make sure that we never allow a 304 Not Modified response
2157 that we asked for to leak to the client should the 304 response be
2158 uncacheable. PR45341 [Graham Leggett]
2160 *) mod_cache: Add the cache_status hook to register the final cache
2161 decision hit/miss/revalidate. Add optional support for an X-Cache
2162 and/or an X-Cache-Detail header to add the cache status to the
2163 response. PR48241 [Graham Leggett]
2165 *) mod_authz_host: Add 'local' provider that matches connections originating
2166 on the local host. PR 19938. [Stefan Fritsch]
2168 *) Event MPM: Fix crash accessing pollset on worker thread when child
2169 process is exiting. [Jeff Trawick]
2171 *) core: For process invocation (cgi, fcgid, piped loggers and so forth)
2172 pass the system library path (LD_LIBRARY_PATH or platform-specific
2173 variables) along with the system PATH, by default. Both should be
2174 overridden together as desired using PassEnv etc; see mod_env.
2177 *) mod_cache: Introduce CacheStoreExpired, to allow administrators to
2178 capture a stale backend response, perform If-Modified-Since requests
2179 against the backend, and serving from the cache all 304 responses.
2180 This restores pre-2.2.4 cache behavior. [William Rowe]
2182 *) mod_rewrite: Introduce <=, >= string comparison operators, and integer
2183 comparators -lt, -le, -eq, -ge, and -gt. To help bash users and drop
2184 the ambiguity of the symlink test "-ltest", introduce -h or -L as
2185 symlink test operators. [William Rowe]
2187 *) mod_cache: Give the cache provider the opportunity to choose to cache
2188 or not cache based on the buckets present in the brigade, such as the
2189 presence of a FILE bucket.
2192 *) mod_authz_core: Allow authz providers to check args while reading the
2193 config and allow to cache parsed args. Move 'all' and 'env' authz
2194 providers from mod_authz_host to mod_authz_core. Add 'method' authz
2195 provider depending on the HTTP method. [Stefan Fritsch]
2197 *) mod_include: Move the request_rec within mod_include to be
2198 exposed within include_ctx_t. [Graham Leggett]
2200 *) mod_include: Reinstate support for UTF-8 character sets by allowing a
2201 variable being echoed or set to be decoded and then encoded as separate
2202 steps. PR47686 [Graham Leggett]
2204 *) mod_cache: Add a discrete commit_entity() provider function within the
2205 mod_cache provider interface which is called to indicate to the
2206 provider that caching is complete, giving the provider the opportunity
2207 to commit temporary files permanently to the cache in an atomic
2208 fashion. Replace the inconsistent use of error cleanups with a formal
2209 set of pool cleanups attached to a subpool, which is destroyed on error.
2212 *) mod_cache: Change the signature of the store_body() provider function
2213 within the mod_cache provider interface to support an "in" brigade
2214 and an "out" brigade instead of just a single input brigade. This
2215 gives a cache provider the option to consume only part of the brigade
2216 passed to it, rather than the whole brigade as was required before.
2217 This fixes an out of memory and a request timeout condition that would
2218 occur when the original document was a large file. Introduce
2219 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
2220 the amount of data to attempt to cache at a time. [Graham Leggett]
2222 *) core: Add ErrorLogFormat to allow configuring error log format, including
2223 additional information that is logged once per connection or request. Add
2224 error log IDs for connections and request to allow correlating error log
2225 lines and the corresponding access log entry. [Stefan Fritsch]
2227 *) core: Disable sendfile by default. [Stefan Fritsch]
2229 *) mod_cache: Check the request to determine whether we are allowed
2230 to return cached content at all, and respect a "Cache-Control:
2231 no-cache" header from a client. Previously, "no-cache" would
2232 behave like "max-age=0". [Graham Leggett]
2234 *) mod_cache: Use a proper filter context to hold filter data instead
2235 of misusing the per-request configuration. Fixes a segfault on trunk
2236 when the normal handler is used. [Graham Leggett]
2238 *) mod_cgid: Log a warning if the ScriptSock path is truncated because
2239 it is too long. PR 49388. [Stefan Fritsch]

3334 *) core: fix origin checking in SymlinksIfOwnerMatch
3335 PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
3337 *) Activate mod_cache, mod_file_cache and mod_disk_cache as part of the
3338 'most' set for '--enable-modules' and '--enable-shared-mods'. Include
3339 mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
3341 *) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
3342 contain public function declarations which are useful for
3343 third party module authors. PR 42431 [Dirk-Willem van Gulik].
3345 *) mod_dir, mod_negotiation: pass the output filter information
3346 to newly created sub requests; as these are later on used
3347 as true requests with an internal redirect. This allows for
3348 mod_cache et.al. to trap the results of the redirect.
3349 [Dirk-Willem van Gulik, Ruediger Pluem]
3351 *) mod_ldap: Add support (taking advantage of the new APR capability)
3352 for ldap rebind callback while chasing referrals. This allows direct
3353 searches on LDAP servers (in particular MS Active Directory 2003+)
3354 using referrals without the use of the global catalog.

3357 *) ApacheMonitor.exe: Introduce --kill argument for use by the
3358 installer. This will permit the installation tool to remove
3359 all running instances before attempting to remove the .exe.
3362 *) mod_ssl: Add support for OCSP validation of client certificates.
3363 PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
3365 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
3367 *) core: Add the option to keep aside a request body up to a certain
3368 size that would otherwise be discarded, to be consumed by filters
3369 such as mod_include. When enabled for a directory, POST requests
3370 to shtml files can be passed through to embedded scripts as POST
3371 requests, rather being downgraded to GET requests. [Graham Leggett]

3387 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
3389 *) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
3390 to authorize an authenticated user via a "require ldap-group X" directive
3391 where the user is not in group X, but is in a subgroup contained in X.

3411 *) Fix issue which could cause error messages to be written to access logs
3412 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
3414 *) The LockFile directive, which specifies the location of
3415 the accept() mutex lockfile, is deprecated. Instead, the
3416 AcceptMutex directive now takes an optional lockfile
3417 location parameter, ala SSLMutex. [Jim Jagielski]
3419 *) mod_authn_dbd: Export any additional columns queried in the SQL select
3420 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
3421 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
3423 *) mod_dbd: Key the storage of prepared statements on the hex string
3424 value of server_rec, rather than the server name, as the server name
3425 may change (eg when the server name is set) at any time, causing
3426 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
3428 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
3430 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
3431 the first bucket from the brigade, finds it not to be a FILE
3432 bucket and barfs. The fix is to pass a bucket rather than a brigade.

3435 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
3437 *) ap_get_server_version() has been removed. Third-party modules must
3438 now use ap_get_server_banner() or ap_get_server_description().
3441 *) All MPMs: Introduce a check_config phase between pre_config and
3442 open_logs, to allow modules to review interdependent configuration
3443 directive values and adjust them while messages can still be logged
3444 to the console. Handle relevant MPM directives during this phase
3445 and format messages for both the console and the error log, as
3446 appropriate. [Chris Darroch]
3448 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
3449 to circumvent the symbolic link checks imposed by FollowSymLinks and
3450 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]

3453 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
3454 The default is none as this is far greater debugging resolution than
3455 the typical administrator is prepared to untangle. [William Rowe]

3458 within the configured boundaries before actually saving data.

3481 *) mod_charset_lite: Remove Content-Length when output filter can
3482 invalidate it. Warn when input filter can invalidate it.
3485 *) Authz: Add the new module mod_authn_core that will provide common
3486 authn directives such as 'AuthType', 'AuthName'. Move the directives
3487 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
3488 into mod_authn_core. [Brad Nicholes]
3490 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
3491 into the new module mod_access_compat which can be loaded to provide
3492 support for these directives.
3495 *) Authz: Move the 'Require' directive from the core module as well as
3496 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
3497 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
3498 logic into the authorization processing. [Brad Nicholes]
3500 *) Authz: Add the new module mod_authz_core which acts as the
3501 authorization provider vector and contains common authz
3502 directives. [Brad Nicholes]
3504 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
3505 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
3507 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
3508 host-based access control provided by mod_authz_host and invoked
3509 through the 'Require' directive. [Brad Nicholes]
3511 *) Authz: Convert all of the authz modules from hook based to
3512 provider based. [Brad Nicholes]
3514 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
3515 seconds to cache a document.

3521 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
3523 *) Asynchronous write completion for the Event MPM. [Brian Pane]
3525 *) Added an End-Of-Request bucket type. The logging of a request and
3526 the freeing of its pool are now done when the EOR bucket is destroyed.
3527 This has the effect of delaying the logging until right after the last
3528 of the response is sent; ap_core_output_filter() calls the access logger
3529 indirectly when it destroys the EOR bucket. [Brian Pane]
3531 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
3532 and the format of statistical output has changed. [Colm MacCarthaigh]
3534 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
3536 *) Added new connection states for handler and write completion
3539 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
3542 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
3543 allowing string-valued client certificate attributes to be used for
3544 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
