Changes with Apache 2.3.0
[Remove entries to the current 2.0 and 2.2 section below, when backported]
*) mod_deflate: Rework inflate output and deflate output filter to fix several
issues: Incorrect handling of flush buckets, potential memory leaks,
excessive memory usage in inflate output filter for large compressed
content. PR 39854. [Ruediger Pluem, Nick Kew, Justin Erenkrantz]
*) mod_proxy_ajp: Close connection to backend if reading of request body
fails. PR 40310. [Ian Abel <ianabel mxtelecom.com>]
*) 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]
*) mod_proxy: Don't try to use dead backend connection. PR 37770.
*) mod_proxy: don't URLencode tilde in path component
[Stijn Hoop <stijn sandcat.nl>]
*) mpm_winnt: Fix return values from wait_for_many_objects.
The return value is index to the signaled thread in the
creted_threads array. We can not use WAIT_TIMEOUT because
his value is defined as 258, thus limiting the MaxThreads
to that value. [Mladen Turk]
*) mod_proxy_balancer: Workers can now be defined as part of
a balancer cluster "set" in which members of a lower-numbered set
are preferred over higher numbered ones. [Jim Jagielski]
*) SECURITY: CVE-2006-3747 (cve.mitre.org)
mod_rewrite: Fix an off-by-one security problem in the ldap scheme
handling. For some RewriteRules this could lead to a pointer being
written out of bounds. Reported by Mark Dowd of McAfee.
[Mark Cox]
*) mod_cache: While serving a cached entity ensure that filters that have
been applied to this cached entity before saving it to the cache are not
applied again. PR 40090. [Ruediger Pluem]
*) mod_proxy_ajp: Added cping/cpong support for the AJP protocol.
A new worker directive ping=timeout will cause CPING packet
to be send expecting CPONG packet within defined timeout.
In case the backend is too busy this will fail instead
sending the full header. [Mladen Turk]

*) 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]
*) mod_proxy: Support environment variable interpolation in reverse
proxying directives. [Nick Kew]
*) mod_proxy_balancer: Workers can now be defined as "hot standby" which
will only be used if all other workers are unusable (eg: in
error or disabled). Also, the balancer-manager displays the election
count and I/O counts of all workers. [Jim Jagielski]
*) core: Add the filename of the configuration file to the warning message
about the useless use of AllowOverride. PR 39992.
[Darryl Miles <darryl darrylmiles.org>]
*) mod_proxy_balancer: Retry worker chosen by route / redirect worker if
it is in error state before sending "Service Temporarily Unavailable".
PR 38962. [Christian Boitel <cboitel lfdj.com>]
*) mod_proxy_balancer: Add information about the route, the sticky session
and the worker used during a request as environment variables. PR 39806.
[Brian <brectanu gmail.com>]
*) mod_isapi: Avoid double trailing slashes in HSE_REQ_MAP_URL_TO_PATH
support. Also corrects the slashes for Windows. PR 15993. [William Rowe]
*) mod_isapi: Handle "HTTP/1.1 200 OK" style status lines correctly, the
token parser worked while the resulting length was misinterpreted.
PR 29098 [Brock Bland <bbland serena.com>]
*) mod_isapi: Return 0 (failure) for more of the various ap_pass_brigade
attempts to stream the response at the client. PR 30022 [William Rowe]
William A. Rowe Jr
committed
*) mod_isapi: Ensure we walk through all the methods the developer may have
employed to report their HTTP status result code.
PR 16637 30033 28089 [Matt Lewandowsky <matt iamcode.net>, 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>]
*) mod_cache: Convert all values to seconds before comparing them when
checking whether to send a Warning header for a stale response.
PR 39713. [Owen Taylor <otaylor redhat.com>]
Ruediger Pluem
committed
*) mod_disk_cache: Delete temporary files if they cannot be renamed to their
final name. [Davi Arnaut <davi haxent.com.br>]
*) 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]
*) mod_ssl: Fix spurious hostname mismatch warning for valid
wildcard certificates. PR 37911. [Nick Burch <nick torchbox.com>]
*) 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]
Ruediger Pluem
committed
*) Authz: Mark the directives 'Order', 'Allow', 'Deny' and 'Satisfy' as
deprecated and move them into the new module mod_access_compat which
can be loaded to provide backwards compatibility for these directives.
[Brad Nicholes]
Ruediger Pluem
committed
*) 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]
Ruediger Pluem
committed
*) 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")
[Martin Kraemer, David Reid]
*) mod_authn_alias: Add a check to make sure that the base provider and the
alias names are different and also that the alias has not been registered
before. PR 40051. [Brad Nicholes]
