Changes with Apache 2.3.0
[Remove entries to the current 2.0 and 2.2 section below, when backported]
*) mod_cache: Fix an out of memory condition that occurs when the
cache tries to save huge files (greater than RAM). Buckets bigger
than a tuneable threshold are split into smaller buckets before
being passed to mod_disk_cache, etc. PR 39380 [Graham Leggett]
*) 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 depreciated. Instead, the
AcceptMutex directive now takes an optional lockfile
location parameter, ala SSLMutex. [Jim Jagielski]
*) Fix address-in-use startup failure caused by corruption of the list of
listen sockets in some configurations with multiple generic Listen
directives. [Jeff Trawick]
*) 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]
*) mod_authnz_ldap: Add an AuthLDAPRemoteUserAttribute directive. If
set, REMOTE_USER will be set to this attribute, rather than the
username supplied by the user. Useful for example when you want users
to log in using an email address, but need to supply a userid instead
to the backend. [Graham Leggett]
*) Allow mod_dumpio to log at other than DEBUG levels via
the new DumpIOLogLevel directive. [Jim Jagielski]
*) mod_disk_cache: Implement read-while-caching.
[Niklas Edmundsson <nikke acc.umu.se>]
*) mod_disk_cache: NULL fd pointers when closing them, fix missing
close/flush, remove some unneccessary code duplication instead
of calling the right helper in replace_brigade_with_cache().
[Niklas Edmundsson <nikke acc.umu.se>]
*) 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_disk_cache: Do away with the write-to-file-then-move-in-place
mentality. [Niklas Edmundsson <nikke acc.umu.se>]
*) mod_rewrite: support rewritemap by SQL query [Nick Kew]
*) Fix issue which could cause piped loggers to be orphaned and never
terminate after a graceful restart. PR 40651. [Joe Orton,
Ruediger Pluem]
*) mod_headers: support regexp-based editing of HTTP headers [Nick Kew]
*) mod_cache: Eliminate a bogus error in the log when a filter returns
AP_FILTER_ERROR. [Niklas Edmundsson <nikke acc.umu.se>]
*) mod_disk_cache: Make caching of large files possible on 32bit machines
by determining whether the cached file should be copied on disk rather
than loaded into RAM. PR39380 [Niklas Edmundsson <nikke acc.umu.se>]
*) mod_mem_cache: Convert mod_mem_cache to use APR memory pool functions
by creating a root pool for object persistence across requests. This
also eliminates the need for custom serialization code.
[Davi Arnaut <davi haxent.com.br>]
*) mod_mem_cache: Memory leak fix: Unconditionally free the buffer.
[Davi Arnaut <davi haxent.com.br>]

*) mod_proxy_balancer: Set the new environment variable BALANCER_ROUTE_CHANGED
if a worker with a route different from the one supplied by the client
had been chosen or if the client supplied no routing information for
a balancer with sticky sessions. [Ruediger Pluem]

*) mod_proxy: Print the correct error message for erroneous configured
ProxyPass directives. PR 40439. [serai lans-tv.com]
*) Allow htcacheclean, httxt2dbm, and fcgistarter to link apr/apr-util
statically like the older support programs.
[Eric Covener <covener gmail.com>]
*) ap_get_server_version() has been removed. Third-party modules must
now use ap_get_server_banner() or ap_get_server_description().
[Jeff Trawick]
*) mod_proxy_balancer: Extract stickysession routing information contained as
parameter in the URL correctly. PR 40400.
[Ruediger Pluem, Tomokazu Harada <harada sysrdc.ns-sol.co.jp>]
*) 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]
*) 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]
*) 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]

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]
*) 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: Add information about the route, the sticky session
and the worker used during a request as environment variables. PR 39806.
[Brian <brectanu gmail.com>]
*) 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>]

*) 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
