null value. [David Shane Holden <dpejesh apache.org>]

*) core, authn/z: Determine registered authn/z providers directly in

*) core: When testing for slash-terminated configuration paths in

[Chris Darroch]

*) core, mod_proxy: If a kept_body is present, it becomes safe for

subrequests to support message bodies. Make sure that safety

checks within the core and within the proxy are not triggered

when kept_body is present. This makes it possible to embed

proxied POST requests within mod_include. [Graham Leggett]

*) mod_auth_form: Make sure the input filter stack is properly set

up before reading the login form. Make sure the kept body filter

is correctly inserted to ensure the body can be read a second

time safely should the authn be successful. [Graham Leggett,

Ruediger Pluem]

*) mod_request: Insert the KEPT_BODY filter via the insert_filter

hook instead of during fixups. Add a safety check to ensure the

filters cannot be inserted more than once. [Graham Leggett,

Ruediger Pluem]

*) ap_cache_cacheable_headers_out() will (now) always

merge an error headers _before_ clearing them and _before_

merging in the actual entity headers and doing normal

hop-by-hop cleansing. [Dirk-Willem van Gulik].

*) cache: retire ap_cache_cacheable_hdrs_out() which was used

for both in- and out-put headers; and replace it by a single

ap_cache_cacheable_headers() wrapped in a in- and out-put

specific ap_cache_cacheable_headers_in()/out(). The latter

which will also merge error and ensure content-type. To keep

cache modules consistent with ease. This API change bumps

up the minor MM by one [Dirk-Willem van Gulik].

*) Move the KeptBodySize directive, kept_body filters and the

ap_parse_request_body function out of the http module and into a

new module called mod_request, reducing the size of the core.

[Graham Leggett]

*) mod_dbd: Handle integer configuration directive parameters with a

dedicated function.

*) Change the directives within the mod_session* modules to be valid

both inside and outside the location/directory sections, as

suggested by wrowe. [Graham Leggett]

*) mod_auth_form: Add a module capable of allowing end users to log

in using an HTML form, storing the credentials within mod_session.

[Graham Leggett]

*) Add a function to the http filters that is able to parse an HTML

form request with the type of application/x-www-form-urlencoded.

[Graham Leggett]

*) mod_session_crypto: Initialise SSL in the post config hook.

[Ruediger Pluem, Graham Leggett]

*) mod_session_dbd: Add a session implementation capable of storing

session information in a SQL database via the dbd interface. Useful

for sites where session privacy is important. [Graham Leggett]

*) mod_session_crypto: Add a session encoding implementation capable

of encrypting and decrypting sessions wherever they may be stored.

Introduces a level of privacy when sessions are stored on the

browser. [Graham Leggett]

*) mod_session_cookie: Add a session implementation capable of storing

session information within cookies on the browser. Useful for high

volume sites where server bound sessions are too resource intensive.

[Graham Leggett]

*) mod_session: Add a generic session interface to unify the different

attempts at saving persistent sessions across requests.

[Graham Leggett]

*) core, authn/z: Avoid calling access control hooks for internal requests

with configurations which match those of initial request. Revert to

original behaviour (call access control hooks for internal requests

with URIs different from initial request) if any access control hooks or

providers are not registered as permitting this optimization.

Introduce wrappers for access control hook and provider registration

which can accept additional mode and flag data. [Chris Darroch]

*) Introduced ap_expr API for expression evaluation.

This is adapted from mod_include, which is the first module

to use the new API.

[Nick Kew]

*) mod_authz_dbd: When redirecting after successful login/logout per

AuthzDBDRedirectQuery, do not report authorization failure, and use

first row returned by database query instead of last row.

*) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these

third party module authors. PR 42431 [Dirk-Willem van Gulik].

*) mod_dir, mod_negotiation: pass the output filter information

to newly created sub requests; as these are later on used

as true requests with an internal redirect. This allows for

mod_cache et.al. to trap the results of the redirect.

[Dirk-Willem van Gulik, Ruediger Pluem]

*) mod_ldap: Add support (taking advantage of the new APR capability)

for ldap rebind callback while chasing referrals. This allows direct

searches on LDAP servers (in particular MS Active Directory 2003+)

using referrals without the use of the global catalog.

PRs 26538, 40268, and 42557 [Paul J. Reder]

*) The LockFile directive, which specifies the location of

AcceptMutex directive now takes an optional lockfile

location parameter, ala SSLMutex. [Jim Jagielski]

*) mod_authn_dbd: Export any additional columns queried in the SQL select

into the environment with the name AUTHENTICATE_<COLUMN>. This brings

mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]

*) mod_dbd: Key the storage of prepared statements on the hex string

value of server_rec, rather than the server name, as the server name

may change (eg when the server name is set) at any time, causing

weird behaviour in modules dependent on mod_dbd. [Graham Leggett]

*) mod_proxy_fcgi: Added win32 build. [Mladen Turk]

*) sendfile_nonblocking() takes the _brigade_ as an argument, gets

the first bucket from the brigade, finds it not to be a FILE

bucket and barfs. The fix is to pass a bucket rather than a brigade.

*) All MPMs: Introduce a check_config phase between pre_config and

open_logs, to allow modules to review interdependent configuration

directive values and adjust them while messages can still be logged

to the console. Handle relevant MPM directives during this phase

and format messages for both the console and the error log, as

appropriate. [Chris Darroch]

*) core: Do not allow internal redirects like the DirectoryIndex of mod_dir

to circumvent the symbolic link checks imposed by FollowSymLinks and

SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]

*) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]

configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.

The default is none as this is far greater debugging resolution than

the typical administrator is prepared to untangle. [William Rowe]

within the configured boundaries before actually saving data.

authn directives such as 'AuthType', 'AuthName'. Move the directives

'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias

into mod_authn_core. [Brad Nicholes]

*) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'

into the new module mod_access_compat which can be loaded to provide

support for these directives.

[Brad Nicholes]

*) Authz: Move the 'Require' directive from the core module as well as

add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'

and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'

logic into the authorization processing. [Brad Nicholes]

*) Authz: Add the new module mod_authz_core which acts as the

authorization provider vector and contains common authz

directives. [Brad Nicholes]

*) Authz: Renamed mod_authz_dbm authz providers from 'group' and

'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]

*) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle

host-based access control provided by mod_authz_host and invoked

through the 'Require' directive. [Brad Nicholes]

*) Authz: Convert all of the authz modules from hook based to

provider based. [Brad Nicholes]

*) Asynchronous write completion for the Event MPM. [Brian Pane]

*) Added an End-Of-Request bucket type. The logging of a request and

the freeing of its pool are now done when the EOR bucket is destroyed.

This has the effect of delaying the logging until right after the last

indirectly when it destroys the EOR bucket. [Brian Pane]
