Changes with Apache 2.3.0
[Remove entries to the current 2.0 and 2.2 section below, when backported]
*) 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]
*) mod_dbd: Handle error conditions in dbd_construct() properly.
Simplify ap_dbd_open() and use correct arguments to apr_dbd_error()
when non-threaded. Register correct cleanup data in non-threaded
ap_dbd_acquire() and ap_dbd_cacquire(). Clean up configuration data
and merge function. Use ap_log_error() wherever possible.
[Chris Darroch, Nick Kew]
*) mod_proxy_http: Handle request bodies larger than 2 GB by converting
the Content-Length header of the request correctly. PR 40883.
[Ruediger Pluem, toadie <toadie643 gmail.com>]
*) core: Do not replace a Date header set by a proxied backend server.
PR 40232. [Ruediger Pluem]
Ruediger Pluem
committed
*) mod_proxy: Ensure that at least scheme://hostname[:port] matches between
worker and URL when searching for the best fitting worker for a given URL.
PR 40910. [Ruediger Pluem]
*) mod_cache: Remove expired content from cache that cannot be revalidated.
PR 30370. [Ruediger Pluem]
*) mod_dbd: Stash DBD connections in request_config of initial request
only, or else sub-requests and internal redirections may cause
entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
*) mod_cache: Correctly cache objects whose URL query string has been
modified by mod_rewrite. PR 40805. [Ruediger Pluem]
*) mod_proxy: Add a missing assignment in an error checking code path.
PR 40865. [Andrew Rucker Jones <arjones simultan.dyndns.org>]
Ruediger Pluem
committed
*) mod_mem_cache: Increase the minimum and default value for
MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not
make sense and leads to a division by zero. PR 40576.
[Xuekun Hu <xuekun.hu gmail.com>]
*) mod_cache: Pass the output filter stack through the store_body()
hook, giving each cache backend the ability to make a better
decision as to how it will allocate the tasks of writing to the
cache and writing to the network. Previously the write to the
cache task needed to be complete before the same brigade was
written to the network, and this caused timing and memory issues
on large cached files. This fix replaces the previous fix for this
PR below. PR39380 [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]
*) 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_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]
*) 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>]
Ruediger Pluem
committed
*) mod_proxy: Print the correct error message for erroneous configured
ProxyPass directives. PR 40439. [serai lans-tv.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]
*) 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 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_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]

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

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>]
*) 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]
