56 *) mod_dav: Avoid a potential integer underflow in the lock timeout value sent
57 back to a client. The answer to a LOCK request could be an extremly large
58 integer if the time needed to lock the resource was longer that the
59 requested timeout given in the LOCK request. In such a case, we now answer
63 *) mod_cgid: Within the first minute of a server start or restart,
64 allow mod_cgid to retry connecting to its daemon process. Previously,

79 context for directories found by mod_userdir and mod_alias. These no
80 longer require RewriteBase to be specified. [Eric Covener]

83 finally close those not meant to be kept alive by SetEnv proxy-nokeepalive
84 or force-proxy-request-1.0. [Yann Ylavic]

88 default the one of the first virtual host bound to the same IP:port.
89 PR56226. [Yann Ylavic]

179 *) mod_buffer: Forward flushed input data immediately and avoid (unlikely)
180 access to freed memory. [Yann Ylavic, Christophe Jaillet]
182 *) core: Add CGIPassAuth directive to control whether HTTP authorization
183 headers are passed to scripts as CGI variables. PR 56855. [Jeff
186 *) mod_ssl: New directive SSLSessionTickets (On|Off).
187 The directive controls the use of TLS session tickets (RFC 5077),
188 default value is "On" (unchanged behavior).
189 Session ticket creation uses a random key created during web
190 server startup and recreated during restarts. No other key
191 recreation mechanism is available currently. Therefore using session
192 tickets without restarting the web server with an appropriate frequency
193 (e.g. daily) compromises perfect forward secrecy. [Rainer Jung]

2357 processes. Add end_generation hook for notification when the last
2358 MPM child of a generation exits. [Jeff Trawick]

2361 process as opposed to disabling caching completely. This allows to use
2362 the non-shared-memory cache as a workaround for the shared memory cache
2363 not being available during graceful restarts. PR 48958. [Stefan Fritsch]

2426 restart, such that processes of the previous generation were not
2427 observable. [Jeff Trawick]
2429 Changes with Apache 2.3.11
2431 *) mod_win32: Added shebang check for '! so that .vbs scripts work as CGI.

2519 *) mod_authz_core: Fix bug in merging logic if user-based and non-user-based
2520 authorization directives were mixed. [Stefan Fritsch]
2522 *) mod_authn_socache: change directive name from AuthnCacheProvider
2523 to AuthnCacheProvideFor. The term "provider" is overloaded in
2524 this module, and we should avoid confusion between the provider
2525 of a backend (AuthnCacheSOCache) and the authn provider(s) for
2526 which this module provides cacheing (AuthnCacheProvideFor).
2529 *) mod_proxy_http: Allocate the fake backend request from a child pool
2530 of the backend connection, instead of misusing the pool of the frontend
2531 request. Fixes a thread safety issue where buckets set aside in the
2532 backend connection leak into other threads, and then disappear when
2533 the frontend request is cleaned up, in turn causing corrupted buckets
2534 to make other threads spin. [Graham Leggett]

2561 the port over a wildcard (or omitted) port instead of favoring the one
2562 that came first in the configuration file. [Eric Covener]

2767 *) mod_disk_cache: Change on-disk header file format to support the
2768 link of the device/inode of the data file to the matching header
2769 file, and to support the option of not writing a data file when
2770 the data file is empty. [Graham Leggett]
2772 *) core/mod_unique_id: Add generate_log_id hook to allow to use
2773 the ID generated by mod_unique_id as error log ID for requests.

2824 *) mod_cache: Add a discrete commit_entity() provider function within the
2825 mod_cache provider interface which is called to indicate to the
2826 provider that caching is complete, giving the provider the opportunity
2827 to commit temporary files permanently to the cache in an atomic
2828 fashion. Replace the inconsistent use of error cleanups with a formal
2829 set of pool cleanups attached to a subpool, which is destroyed on error.
2832 *) mod_cache: Change the signature of the store_body() provider function
2833 within the mod_cache provider interface to support an "in" brigade
2834 and an "out" brigade instead of just a single input brigade. This
2835 gives a cache provider the option to consume only part of the brigade
2836 passed to it, rather than the whole brigade as was required before.
2837 This fixes an out of memory and a request timeout condition that would
2838 occur when the original document was a large file. Introduce
2839 CacheReadSize and CacheReadTime directives to mod_disk_cache to control
2840 the amount of data to attempt to cache at a time. [Graham Leggett]

3838 *) mod_session_cookie: Make sure that cookie attributes are correctly
3839 included in the blank cookie when cookies are removed. This fixes an
3840 inability to log out when using mod_auth_form. [Graham Leggett]
3842 *) mod_session: Prevent a segfault when a CGI script sets a cookie with a
3843 null value. [David Shane Holden <dpejesh apache.org>]
3845 *) core, authn/z: Determine registered authn/z providers directly in
3846 ap_setup_auth_internal(), which allows optional functions that just
3847 wrapped ap_list_provider_names() to be removed from authn/z modules.
3850 *) authn/z: Convert common provider version strings to macros.
3853 *) core: When testing for slash-terminated configuration paths in
3854 ap_location_walk(), don't look past the start of an empty string
3855 such as that created by a <Location ""> directive.
3858 *) core, mod_proxy: If a kept_body is present, it becomes safe for
3859 subrequests to support message bodies. Make sure that safety
3860 checks within the core and within the proxy are not triggered
3861 when kept_body is present. This makes it possible to embed
3862 proxied POST requests within mod_include. [Graham Leggett]
3864 *) mod_auth_form: Make sure the input filter stack is properly set
3865 up before reading the login form. Make sure the kept body filter
3866 is correctly inserted to ensure the body can be read a second
3867 time safely should the authn be successful. [Graham Leggett,
3870 *) mod_request: Insert the KEPT_BODY filter via the insert_filter
3871 hook instead of during fixups. Add a safety check to ensure the
3872 filters cannot be inserted more than once. [Graham Leggett,
3875 *) ap_cache_cacheable_headers_out() will (now) always
3876 merge an error headers _before_ clearing them and _before_
3877 merging in the actual entity headers and doing normal
3878 hop-by-hop cleansing. [Dirk-Willem van Gulik].
3880 *) cache: retire ap_cache_cacheable_hdrs_out() which was used
3881 for both in- and out-put headers; and replace it by a single
3882 ap_cache_cacheable_headers() wrapped in a in- and out-put
3883 specific ap_cache_cacheable_headers_in()/out(). The latter
3884 which will also merge error and ensure content-type. To keep
3885 cache modules consistent with ease. This API change bumps
3886 up the minor MM by one [Dirk-Willem van Gulik].
3888 *) Move the KeptBodySize directive, kept_body filters and the
3889 ap_parse_request_body function out of the http module and into a
3890 new module called mod_request, reducing the size of the core.
3893 *) mod_dbd: Handle integer configuration directive parameters with a
3896 *) Change the directives within the mod_session* modules to be valid
3897 both inside and outside the location/directory sections, as
3898 suggested by wrowe. [Graham Leggett]
3900 *) mod_auth_form: Add a module capable of allowing end users to log
3901 in using an HTML form, storing the credentials within mod_session.
3904 *) Add a function to the http filters that is able to parse an HTML
3905 form request with the type of application/x-www-form-urlencoded.
3908 *) mod_session_crypto: Initialise SSL in the post config hook.
3909 [Ruediger Pluem, Graham Leggett]
3911 *) mod_session_dbd: Add a session implementation capable of storing
3912 session information in a SQL database via the dbd interface. Useful
3913 for sites where session privacy is important. [Graham Leggett]
3915 *) mod_session_crypto: Add a session encoding implementation capable
3916 of encrypting and decrypting sessions wherever they may be stored.
3917 Introduces a level of privacy when sessions are stored on the
3918 browser. [Graham Leggett]
3920 *) mod_session_cookie: Add a session implementation capable of storing
3921 session information within cookies on the browser. Useful for high
3922 volume sites where server bound sessions are too resource intensive.
3925 *) mod_session: Add a generic session interface to unify the different
3926 attempts at saving persistent sessions across requests.
3929 *) core, authn/z: Avoid calling access control hooks for internal requests
3930 with configurations which match those of initial request. Revert to
3931 original behaviour (call access control hooks for internal requests
3932 with URIs different from initial request) if any access control hooks or
3933 providers are not registered as permitting this optimization.
3934 Introduce wrappers for access control hook and provider registration
3935 which can accept additional mode and flag data. [Chris Darroch]
3937 *) Introduced ap_expr API for expression evaluation.
3938 This is adapted from mod_include, which is the first module
3942 *) mod_authz_dbd: When redirecting after successful login/logout per
3943 AuthzDBDRedirectQuery, do not report authorization failure, and use
3944 first row returned by database query instead of last row.
3947 *) mod_ldap: Correctly return all requested attribute values
3948 when some attributes have a null value.

3963 third party module authors. PR 42431 [Dirk-Willem van Gulik].
3965 *) mod_dir, mod_negotiation: pass the output filter information
3966 to newly created sub requests; as these are later on used
3967 as true requests with an internal redirect. This allows for
3968 mod_cache et.al. to trap the results of the redirect.
3969 [Dirk-Willem van Gulik, Ruediger Pluem]
3971 *) mod_ldap: Add support (taking advantage of the new APR capability)
3972 for ldap rebind callback while chasing referrals. This allows direct
3973 searches on LDAP servers (in particular MS Active Directory 2003+)
3974 using referrals without the use of the global catalog.

3977 *) ApacheMonitor.exe: Introduce --kill argument for use by the
3978 installer. This will permit the installation tool to remove
3979 all running instances before attempting to remove the .exe.
3982 *) mod_ssl: Add support for OCSP validation of client certificates.

3985 *) mod_serf: New module for Reverse Proxying. [Paul Querna]
3987 *) core: Add the option to keep aside a request body up to a certain
3988 size that would otherwise be discarded, to be consumed by filters
3989 such as mod_include. When enabled for a directory, POST requests
3990 to shtml files can be passed through to embedded scripts as POST
3991 requests, rather being downgraded to GET requests. [Graham Leggett]

4037 location parameter, ala SSLMutex. [Jim Jagielski]
4039 *) mod_authn_dbd: Export any additional columns queried in the SQL select
4040 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
4041 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
4043 *) mod_dbd: Key the storage of prepared statements on the hex string
4044 value of server_rec, rather than the server name, as the server name
4045 may change (eg when the server name is set) at any time, causing
4046 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
4048 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
4050 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
4051 the first bucket from the brigade, finds it not to be a FILE
4052 bucket and barfs. The fix is to pass a bucket rather than a brigade.

4055 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
4057 *) ap_get_server_version() has been removed. Third-party modules must
4058 now use ap_get_server_banner() or ap_get_server_description().
4061 *) All MPMs: Introduce a check_config phase between pre_config and
4062 open_logs, to allow modules to review interdependent configuration
4063 directive values and adjust them while messages can still be logged
4064 to the console. Handle relevant MPM directives during this phase

4105 *) Authz: Add the new module mod_authn_core that will provide common
4106 authn directives such as 'AuthType', 'AuthName'. Move the directives
4107 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
4108 into mod_authn_core. [Brad Nicholes]
4110 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'

4116 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
4117 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
4118 logic into the authorization processing. [Brad Nicholes]
4120 *) Authz: Add the new module mod_authz_core which acts as the
4121 authorization provider vector and contains common authz
4122 directives. [Brad Nicholes]

4145 *) Added an End-Of-Request bucket type. The logging of a request and
4146 the freeing of its pool are now done when the EOR bucket is destroyed.
4147 This has the effect of delaying the logging until right after the last
