Changes with Apache 2.3.0
[Remove entries to the current 2.0 and 2.2 section below, when backported]
*) 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]
Ruediger Pluem
committed
*) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
Ruediger Pluem
committed
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]
*) 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]
Ruediger Pluem

committed
*) 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]
Changes with Apache 2.2.4
*) mod_isapi: Correctly present SERVER_PORT_SECURE.
PR: 40573. [Matt Eaton <asf divinehawk.com>]
*) Allow htcacheclean, httxt2dbm, and fcgistarter to link apr/apr-util
statically like the older support programs.
[Eric Covener <covener gmail.com>]
*) core: Fix NONBLOCK status of listening sockets on restart/graceful
PR 37680. [Darius Davis <darius-abz free-range.com.au>]
*) 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_mem_cache: Memory leak fix: Unconditionally free the buffer.
[Davi Arnaut <davi haxent.com.br>]
*) Allow mod_dumpio to log at other than DEBUG levels via
the new DumpIOLogLevel directive. [Jim Jagielski]
*) rotatelogs: Improve error message for open failures. PR 39487.
[Joe Orton]
*) Better detection and clean up of ldap connection that has been
terminated by the ldap server. PR 40878.
[Rob Baily <rbaily servicebench com>]
*) 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_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
*) mod_cgi and mod_cgid: Don't use apr_status_t error return
from input filters as HTTP return value from the handler.
*) mod_cache: Eliminate a bogus error in the log when a filter returns
AP_FILTER_ERROR. [Niklas Edmundsson <nikke acc.umu.se>]
*) core: Fix issue which could cause piped loggers to be orphaned and never
terminate after a graceful restart. PR 40651. [Joe Orton, Ruediger Pluem]
*) core: Fix address-in-use startup failure caused by corruption of the list
of listen sockets in some configurations with multiple generic Listen
*) mod_headers: Support regexp-based editing of HTTP headers. [Nick Kew]
*) mod_proxy: Add explicit flushing feature. When Servlet container sends AJP
body message with size 0, this means that Servlet container has asked for
an explicit flush. Create flush bucket in that case. This feature has been
added to the recent Tomcat versions without breaking the AJP protocol.
[Mladen Turk]
*) 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_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_proxy: Don't try to use dead backend connection. PR 37770.
[Olivier BOEL <ob dorrboel.com>]
*) 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_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]
*) mod_cache: From RFC3986 (section 6.2.3.) if a URI contains an
authority component and an empty path, the empty path is to be equivalent
to "/". It explicitly cites the following four URIs as equivalents:
http://example.com
http://example.com/
http://example.com:/
http://example.com:80/
[Davi Arnaut <davi haxent.com.br>]
*) mod_cache: Don't cache requests with a expires date in the past;
otherwise mod_cache will always try to cache the URL. This bug
might lead to numerous rename() errors on win32 if the URL was
previously cached. [Davi Arnaut <davi haxent.com.br>]
*) mod_disk_cache: Make sure that only positive integers are accepted
for the CacheMaxFileSize and CacheMinFileSize parameters in the
config file. PR39380. [Niklas Edmundsson <nikke acc.umu.se>]
*) core: Deal with the widespread use of apr_status_t return values
as HTTP status codes, as documented in PR#31759 (a bug shared by
the default handler, mod_cgi, mod_cgid, mod_proxy, and probably
others). PR31759. [Jeff Trawick, Ruediger Pluem, Joe Orton]
*) mod_ext_filter: Handle filter names which include capital letters.
PR 40323. [Jeff Trawick]
*) 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. Log these as well.
PR 30022, 40470. [William Rowe, Matt Eaton <asf divinehawk.com>]
*) 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]
*) mod_echo: Fix precedence problem in if statement. PR 40658.
[Larry Cipriani <lvc lucent.com>]
*) mod_mime_magic: Fix precedence problem in if statement. PR 40656.
[Larry Cipriani <lvc lucent.com>]
*) The full server version information is now included in the error log at
startup as well as server status reports, irrespective of the setting
of the ServerTokens directive. ap_get_server_version() is now
deprecated, and is replaced by ap_get_server_banner() and
ap_get_server_description(). [Jeff Trawick]
*) 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]
*) 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]
*) mod_proxy_ajp: Close connection to backend if reading of request body
fails. PR 40310. [Ian Abel <ianabel mxtelecom.com>]
*) mod_proxy_balancer: Retry worker chosen by route / redirect worker if
it is in error state before sending "Service Temporarily Unavailable".

*) Add optional 'scheme://' prefix to ServerName directive,
allowing correct determination of the canonical server URL
for use behind a proxy or offload device handling SSL; fixing
redirect generation in those cases. PR 33398. [Sander Temme]

take a long time. PR 39275.
[Greg Ames, Jeff Trawick, Chris Darroch <chrisd pearsoncmg.com> ]

bundled version of APR at build time. [Joe Orton]
*) Respect GracefulShutdownTimeout in the worker and event MPMs.
[Chris Darroch, Garrett Rooney]
