*) mod_cache: Add a discrete commit_entity() provider function within the
mod_cache provider interface which is called to indicate to the
provider that caching is complete, giving the provider the opportunity
to commit temporary files permanently to the cache in an atomic
fashion. Replace the inconsistent use of error cleanups with a formal
set of pool cleanups attached to a subpool, which is destroyed on error.
[Graham Leggett]
*) mod_cache: Change the signature of the store_body() provider function
within the mod_cache provider interface to support an "in" brigade
and an "out" brigade instead of just a single input brigade. This
gives a cache provider the option to consume only part of the brigade
passed to it, rather than the whole brigade as was required before.
This fixes an out of memory and a request timeout condition that would

during a per-dir renegotiation. PR 39243. [Joe Orton]
*) mod_proxy_fdpass: New module to pass a client connection over to a separate
process that is reading from a unix daemon socket.
*) mod_ssl: Improve environment variable extraction to be more
efficient and to correctly handle DNs with duplicate tags.
PR 45975. [Joe Orton]
*) Remove the obsolete serial attribute from the RPM spec file. Compile
against the external pcre. Add missing binaries fcgistarter, and
mod_socache* and mod_session*. [Graham Leggett]
Changes with Apache 2.3.0
*) mod_ratelimit: New module to do bandwidth rate limiting. [Paul Querna]
*) Remove X-Pad header which was added as a work around to a bug in
Netscape 2.x to 4.0b2. [Takashi Sato <takashi lans-tv.com>]
*) Add DTrace Statically Defined Tracing (SDT) probes.
[Theo Schlossnagle <jesus omniti.com>, Paul Querna]
*) mod_proxy_balancer: Move all load balancing implementations
as individual, self-contained mod_proxy submodules under
modules/proxy/balancers [Jim Jagielski]
*) Rename APIs to include ap_ prefix:
find_child_by_pid -> ap_find_child_by_pid
suck_in_APR -> ap_suck_in_APR
sys_privileges_handlers -> ap_sys_privileges_handlers
unixd_accept -> ap_unixd_accept

unixd_set_proc_mutex_perms -> ap_unixd_set_proc_mutex_perms
unixd_set_rlimit -> ap_unixd_set_rlimit
[Paul Querna]
*) mod_lbmethod_heartbeat: New module to load balance mod_proxy workers
based on heartbeats. [Paul Querna]
*) mod_heartmonitor: New module to collect heartbeats, and write out a file
so that other modules can load balance traffic as needed. [Paul Querna]
*) mod_heartbeat: New module to generate multicast heartbeats to know if a
server is online. [Paul Querna]
*) mod_buffer: Honour the flush bucket and flush the buffer in the
input filter. Make sure that metadata buckets are written to
the buffer, not to the final brigade. [Graham Leggett]
*) mod_buffer: Optimise the buffering of heap buckets when the heap
buckets stay exactly APR_BUCKET_BUFF_SIZE long. [Graham Leggett,
Ruediger Pluem]
*) mod_buffer: Optional support for buffering of the input and output
filter stacks. Can collapse many small buckets into fewer larger
buckets, and prevents excessively small chunks being sent over
the wire. [Graham Leggett]
*) mod_privileges: new module to make httpd on Solaris privileges-aware
and to enable different virtualhosts to run with different
privileges and Unix user/group IDs [Nick Kew]
*) mod_mem_cache: this module has been removed. [William Rowe]
*) authn/z: Remove mod_authn_default and mod_authz_default.
[Chris Darroch]
*) authz: Fix handling of authz configurations, make default authz
logic replicate 2.2.x authz logic, and replace <Satisfy*>, Reject,
and AuthzMergeRules directives with Match, <Match*>, and AuthzMerge
directives. [Chris Darroch]
*) mod_authn_core: Prevent crash when provider alias created to
provider which is not yet registered. [Chris Darroch]
*) mod_authn_core: Add AuthType of None to support disabling
authentication. [Chris Darroch]
*) core: Allow <Limit> and <LimitExcept> directives to nest, and
constrain their use to conform with that of other access control
and authorization directives. [Chris Darroch]
*) unixd: turn existing code into a module, and turn the set user/group
and chroot into a child_init function. [Nick Kew]
*) mod_dir: Support "DirectoryIndex disabled"
Suggested By André Warnier <aw ice-sa.com> [Eric Covener]
*) mod_ssl: Send Content-Type application/ocsp-request for POST requests to
OSCP responders. PR 46014 [Dr Stephen Henson <steve openssl.org>]
*) mod_authnz_ldap: don't return NULL-valued environment variables to
other modules. PR 39045 [Francois Pesce <francois.pesce gmail.com>]
*) Don't adjust case in pathname components that are not of interest
to mod_mime. Fixes mod_negotiation's use of such components.
PR 43250 [Basant Kumar Kukreja <basant.kukreja sun.com>]
*) Be tolerant in what you accept - accept slightly broken
status lines from a backend provided they include a valid status code.
PR 44995 [Rainer Jung <rainer.jung kippdata.de>]
*) New module mod_sed: filter Request/Response bodies through sed
[Basant Kumar Kukreja <basant.kukreja sun.com>]
*) mod_auth_form: Make sure that basic authentication is correctly
faked directly after login. [Graham Leggett]
*) mod_session_cookie, mod_session_dbd: Make sure cookies are set both
within the output headers and error output headers, so that the
session is maintained across redirects. [Graham Leggett]
*) mod_auth_form: Make sure the logged in user is populated correctly
after a form login. Fixes a missing REMOTE_USER variable directly
following a login. [Graham Leggett]
*) mod_session_cookie: Make sure that cookie attributes are correctly
included in the blank cookie when cookies are removed. This fixes an
inability to log out when using mod_auth_form. [Graham Leggett]
*) mod_session: Prevent a segfault when a CGI script sets a cookie with a
null value. [David Shane Holden <dpejesh apache.org>]
*) core, authn/z: Determine registered authn/z providers directly in
ap_setup_auth_internal(), which allows optional functions that just
wrapped ap_list_provider_names() to be removed from authn/z modules.
[Chris Darroch]
*) authn/z: Convert common provider version strings to macros.
[Chris Darroch]
*) core: When testing for slash-terminated configuration paths in
ap_location_walk(), don't look past the start of an empty string
such as that created by a <Location ""> directive.
[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.
[Chris Darroch]
*) mod_ldap: Correctly return all requested attribute values
when some attributes have a null value.
PR 44560 [Anders Kaseorg <anders kaseorg.com>]
*) core: check symlink ownership if both FollowSymlinks and
SymlinksIfOwnerMatch are set [Nick Kew]
*) core: fix origin checking in SymlinksIfOwnerMatch
PR 36783 [Robert L Mathews <rob-apache.org.bugs tigertech.net>]
*) Activate mod_cache, mod_file_cache and mod_disk_cache as part of the
'most' set for '--enable-modules' and '--enable-shared-mods'. Include
mod_mem_cache in 'all' as well. [Dirk-Willem van Gulik]
*) Also install mod_so.h, mod_rewrite.h and mod_cache.h; as these
contain public function declarations which are useful for
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]
*) ApacheMonitor.exe: Introduce --kill argument for use by the
installer. This will permit the installation tool to remove
all running instances before attempting to remove the .exe.
[William Rowe]
*) mod_ssl: Add support for OCSP validation of client certificates.
PR 41123. [Marc Stern <marc.stern approach.be>, Joe Orton]
*) mod_serf: New module for Reverse Proxying. [Paul Querna]
*) core: Add the option to keep aside a request body up to a certain
size that would otherwise be discarded, to be consumed by filters
such as mod_include. When enabled for a directory, POST requests
to shtml files can be passed through to embedded scripts as POST
requests, rather being downgraded to GET requests. [Graham Leggett]
*) mod_ssl: Fix TLS upgrade (RFC 2817) support. PR 41231. [Joe Orton]
*) scoreboard: Correctly declare ap_time_process_request.
PR 43789 [Tom Donovan <Tom.Donovan acm.org>]
*) core; scoreboard: ap_get_scoreboard_worker(sbh) now takes the sbh member
from the connection rec, ap_get_scoreboard_worker(proc, thread) will now
provide the unusual legacy lookup. [William Rowe]
*) mpm winnt: fix null pointer dereference
PR 42572 [Davi Arnaut]
*) mod_authnz_ldap, mod_authn_dbd: Tidy up the code to expose authn
parameters to the environment. Improve portability to
EBCDIC machines by using apr_toupper(). [Martin Kraemer]
*) mod_ldap, mod_authnz_ldap: Add support for nested groups (i.e. the ability
to authorize an authenticated user via a "require ldap-group X" directive
where the user is not in group X, but is in a subgroup contained in X.
PR 42891 [Paul J. Reder]
*) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
*) apxs: Enhance -q flag to print all known variables and their values
when invoked without variable name(s).
[William Rowe, Sander Temme]
*) apxs: Eliminate run-time check for mod_so. PR 40653.
[David M. Lee <dmlee crossroads.com>]
*) beos MPM: Create pmain pool and run modules' child_init hooks when
entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
[Chris Darroch]
*) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
cleanups registered in modules' child_init hooks are performed.
[Chris Darroch]
*) Fix issue which could cause error messages to be written to access logs
on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
*) The LockFile directive, which specifies the location of
the accept() mutex lockfile, is deprecated. Instead, the
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.
[Niklas Edmundsson <nikke acc.umu.se>]
*) mod_rewrite: support rewritemap by SQL query [Nick Kew]
*) ap_get_server_version() has been removed. Third-party modules must
now use ap_get_server_banner() or ap_get_server_description().
[Jeff Trawick]
*) 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]
*) mod_disk_cache: If possible, check if the size of an object to cache is
within the configured boundaries before actually saving data.
[Niklas Edmundsson <nikke acc.umu.se>]
*) Worker and event MPMs: Remove improper scoreboard updates which were
performed in the event of a fork() failure. [Chris Darroch]
*) Add support for fcgi:// proxies to mod_rewrite.
[Markus Schiegl <ms schiegl.com>]
*) Remove incorrect comments from scoreboard.h regarding conditional
loading of worker_score structure with mod_status, and remove unused
definitions relating to old life_status field.
[Chris Darroch <chrisd pearsoncmg.com>]
*) Remove allocation of memory for unused array of lb_score pointers
in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
*) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
[Garrett Rooney, Jim Jagielski, Paul Querna]
*) Event MPM: Fill in the scoreboard's tid field. PR 38736.
[Chris Darroch <chrisd pearsoncmg.com>]
*) mod_charset_lite: Remove Content-Length when output filter can
invalidate it. Warn when input filter can invalidate it.
[Jeff Trawick]
*) Authz: Add the new module mod_authn_core that will provide common
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]
*) mod_cache: Add CacheMinExpire directive to set the minimum time in
seconds to cache a document.
[Brian Akins <brian.akins turner.com>, Ruediger Pluem]
*) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
*) Fix typo in ProxyStatus syntax error message.
[Christophe Jaillet <christophe.jaillet wanadoo.fr>]
*) 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
of the response is sent; ap_core_output_filter() calls the access logger
indirectly when it destroys the EOR bucket. [Brian Pane]
*) Rewrite of logresolve support utility: IPv6 addresses are now supported
and the format of statistical output has changed. [Colm MacCarthaigh]
*) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
*) Added new connection states for handler and write completion
[Brian Pane]
*) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
[Justin Erenkrantz]
*) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
allowing string-valued client certificate attributes to be used for
access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
