363N/A *) log core: ensure we use a special pool for stderr logging, so that
363N/A the stderr channel remains valid from the time plog is destroyed,
363N/A until the time the open_logs hook is called again. [William Rowe]
363N/A *) main core: Emit errors during the initial apr_app_initialize()
363N/A or apr_pool_create() (when apr-based error reporting is not ready).
363N/A [William Rowe, Jeff Trawick]
5680N/A *) mpm_winnt: Prevent the parent-child pipe from leaking into other
363N/A stdout when running as-a-service. [William Rowe]
363N/A *) log core: fix the new piped logger case where we couldn't connect
797N/A the replacement stderr logger's stderr to the NULL stdout stream.
797N/A Continue in this case, since the previous alternative of no error
797N/A *) mod_ldap: Avoid possible crashes, hangs, and busy loops due to
797N/A improper merging of the cache lock in vhost config
797N/A *) mod_negotiation: preserve Query String in resolving a type map
797N/A *) mod_deflate: fix content_encoding detection in inflate_out filter
797N/A when it's not in response headers table.
797N/A *) mod_proxy: Improve network performance by setting APR_TCP_NODELAY

363N/A PR 42871 [Christian BOITEL <christian_boitel
yahoo.fr>, Jim Jagielski]
2899N/A *) mod_info: mod_info outputs invalid XHTML 1.0 transitional.
4368N/A *) mod_ldap, mod_authnzldap: Add support for nested groups (
i.e. the ability
4368N/A to authorize an authenticated user via a "require ldap-group X" directive
3817N/A where the user is not in group X, but is in a subgroup contained in X.
3817N/A *) mod_deflate: don't try to process metadata buckets as data. what should
363N/A have been a 413 error was logged as a 500 and a blank screen appeared
1845N/A [Greg Ames, Ruediger Pluem]
364N/A prefork, worker, event MPMs: Ensure that the parent process cannot
797N/A be forced to kill processes outside its process group. [Joe Orton]
363N/A mod_status: Fix a possible XSS attack against a site with a public
363N/A server-status page and ExtendedStatus enabled, for browsers which
363N/A perform charset "detection". Reported by Stefan Esser. [Joe Orton]
5123N/A *) Event MPM: Add support for running under mod_ssl, by reverting to the
5123N/A Worker MPM behaviors, when run under an input filter that buffers
5123N/A its own data. [Paul Querna]
777N/A *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
777N/A mod_mem_cache: Copy headers into longer lived storage; header names and
777N/A values could previously point to cleaned up storage
363N/A *) mod_cache: Do not set Date or Expires when they are missing from
363N/A the original response or are invalid. [Justin Erenkrantz]
363N/A *) mod_cache: Correctly handle HEAD requests on expired cache content.
797N/A PR 41230. [Niklas Edmundsson]
363N/A *) mod_proxy: Added ProxyPassMatch directive, which is similar
363N/A to ProxyPass but takes a regex local path prefix. [Jim Jagielski]
363N/A magic signatures when failing with a 'garbled' message, and solve
363N/A user's confusion by pointing out 'perhaps compiled for a different
363N/A version of apache?'. [William Rowe]
363N/A *) mod_substitute: Added a new experimental output filter, which
363N/A performs inline response content pattern matching (including
363N/A regex) and substitution. [Jim Jagielski]
363N/A *) mod_ssl: Version reporting update; displays 'compiled against'
363N/A Apache and build-time SSL Library versions at loglevel [info],
363N/A while reporting the run-time SSL Library version in the server
363N/A info tags. Helps to identify a mod_ssl built against one flavor
363N/A of OpenSSL but running against another (also adds SSL-C version
363N/A number reporting.) [William Rowe]
363N/A *) core: Change etag generation to produce identical results on
363N/A 32-bit and 64-bit platforms. PR 40064. [Joe Orton]
363N/A *) ab: Add -r option to continue after socket receive errors.
363N/A *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
363N/A for SDKs that define LDAP_NO_LIMIT to something other than -1.
4371N/A *) mod_dbd: Introduce configuration groups to allow inheritance by virtual
4371N/A hosts of database configurations from the main server. Determine the
4907N/A minimal set of distinct configurations and share connection pools
4371N/A whenever possible. Allow virtual hosts to override inherited SQL
363N/A statements. PR 41302. [Chris Darroch]
363N/A *) core: Fix broken chunk filtering that causes all non blocking reads to be

797N/A when invoked without variable name(s).
797N/A [William Rowe, Sander Temme]
363N/A *) mod_dbd: Create memory sub-pools for each DB connection and close
363N/A DB connections in a pool cleanup function. Ensure prepared statements
363N/A are destroyed before DB connection is closed. When using reslists,
363N/A prevent segfaults when child processes exit, and stop memory leakage
363N/A of ap_dbd_t structures. Avoid use of global s->process->pool, which
363N/A isn't destroyed by exiting child processes in most multi-process MPMs.
363N/A PR 39985. [Chris Darroch, Nick Kew]
797N/A *) apxs: Eliminate run-time check for mod_so. PR 40653.
797N/A *) beos MPM: Create pmain pool and run modules' child_init hooks when
797N/A entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
797N/A *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
797N/A cleanups registered in modules' child_init hooks are performed.
797N/A *) mod_dbd: Handle error conditions in dbd_construct() properly.
797N/A Simplify ap_dbd_open() and use correct arguments to apr_dbd_error()
797N/A when non-threaded. Register correct cleanup data in non-threaded
797N/A ap_dbd_acquire() and ap_dbd_cacquire(). Clean up configuration data
797N/A and merge function. Use ap_log_error() wherever possible.
797N/A [Chris Darroch, Nick Kew]
1426N/A *) core: Do not replace a Date header set by a proxied backend server.
797N/A *) mod_proxy: Ensure that at least scheme://hostname[:port] matches between
797N/A worker and URL when searching for the best fitting worker for a given URL.
797N/A PR 40910. [Ruediger Pluem]
797N/A *) mod_cache: Remove expired content from cache that cannot be revalidated.
797N/A PR 30370. [Ruediger Pluem]
797N/A *) mod_dbd: Stash DBD connections in request_config of initial request
797N/A only, or else sub-requests and internal redirections may cause
363N/A entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
363N/A *) mod_proxy: Add a missing assignment in an error checking code path.
363N/A *) mod_mem_cache: Increase the minimum and default value for
363N/A MCacheMinObjectSize from 0 to 1, as a MCacheMinObjectSize of 0 does not
797N/A make sense and leads to a division by zero. PR 40576.
363N/A *) Fix issue which could cause error messages to be written to access logs
363N/A *) The LockFile directive, which specifies the location of
363N/A the accept() mutex lockfile, is deprecated. Instead, the
363N/A AcceptMutex directive now takes an optional lockfile
363N/A location parameter, ala SSLMutex. [Jim Jagielski]
363N/A *) mod_authn_dbd: Export any additional columns queried in the SQL select
363N/A into the environment with the name AUTHENTICATE_<COLUMN>. This brings
363N/A mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
797N/A *) mod_dbd: Key the storage of prepared statements on the hex string
797N/A value of server_rec, rather than the server name, as the server name
363N/A may change (eg when the server name is set) at any time, causing
997N/A weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
4820N/A *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
1951N/A *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
1951N/A the first bucket from the brigade, finds it not to be a FILE
1951N/A bucket and barfs. The fix is to pass a bucket rather than a brigade.
797N/A *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
363N/A *) ap_get_server_version() has been removed. Third-party modules must
3477N/A now use ap_get_server_banner() or ap_get_server_description().
363N/A *) All MPMs: Introduce a check_config phase between pre_config and
797N/A open_logs, to allow modules to review interdependent configuration
797N/A directive values and adjust them while messages can still be logged
1426N/A to the console. Handle relevant MPM directives during this phase
1761N/A and format messages for both the console and the error log, as
1761N/A appropriate. [Chris Darroch]
1426N/A *) mod_proxy: don't URLencode tilde in path component
1426N/A *) mpm_winnt: Fix return values from wait_for_many_objects.
1426N/A The return value is index to the signaled thread in the
1426N/A creted_threads array. We can not use WAIT_TIMEOUT because
1426N/A his value is defined as 258, thus limiting the MaxThreads
1426N/A to that value. [Mladen Turk]
1426N/A *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
1426N/A to circumvent the symbolic link checks imposed by FollowSymLinks and
1426N/A SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
1426N/A *) mod_proxy: Support environment variable interpolation in reverse
1426N/A proxying directives. [Nick Kew]
1426N/A *) core: Add the filename of the configuration file to the warning message
1426N/A about the useless use of AllowOverride. PR 39992.
1426N/A *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
1426N/A configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
1426N/A The default is none as this is far greater debugging resolution than
1426N/A the typical administrator is prepared to untangle. [William Rowe]
1426N/A *) mod_disk_cache: If possible, check if the size of an object to cache is
1426N/A within the configured boundaries before actually saving data.
1426N/A *) mod_cache: Convert all values to seconds before comparing them when
1426N/A checking whether to send a Warning header for a stale response.
1826N/A *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
1426N/A *) Worker and event MPMs: Remove improper scoreboard updates which were
1426N/A performed in the event of a fork() failure. [Chris Darroch]
4820N/A *) Add support for fcgi:// proxies to mod_rewrite.
1426N/A loading of worker_score structure with mod_status, and remove unused
1426N/A definitions relating to old life_status field.
1426N/A *) Remove allocation of memory for unused array of lb_score pointers
1805N/A *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
1426N/A [Garrett Rooney, Jim Jagielski, Paul Querna]
1426N/A *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
1426N/A *) mod_charset_lite: Remove Content-Length when output filter can
1426N/A invalidate it. Warn when input filter can invalidate it.
1426N/A *) mod_ssl: Fix spurious hostname mismatch warning for valid
1426N/A *) Authz: Add the new module mod_authn_core that will provide common
1426N/A authn directives such as 'AuthType', 'AuthName'. Move the directives
1426N/A 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
1426N/A into mod_authn_core. [Brad Nicholes]
797N/A *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
797N/A into the new module mod_access_compat which can be loaded to provide
797N/A support for these directives.
797N/A *) Authz: Move the 'Require' directive from the core module as well as
797N/A add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
797N/A and 'Reject' to mod_authz_core. The new directives introduce '
AND/OR'
797N/A logic into the authorization processing. [Brad Nicholes]
797N/A *) Authz: Add the new module mod_authz_core which acts as the
797N/A authorization provider vector and contains common authz
1688N/A directives. [Brad Nicholes]
1426N/A *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
1426N/A 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
4820N/A *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
1426N/A host-based access control provided by mod_authz_host and invoked
797N/A through the 'Require' directive. [Brad Nicholes]
797N/A *) Authz: Convert all of the authz modules from hook based to
797N/A provider based. [Brad Nicholes]
797N/A *) mod_cache: Add CacheMinExpire directive to set the minimum time in
797N/A seconds to cache a document.
1426N/A *) Fix typo in ProxyStatus syntax error message.
1426N/A *) Asynchronous write completion for the Event MPM. [Brian Pane]
1426N/A *) Added an End-Of-Request bucket type. The logging of a request and
1426N/A the freeing of its pool are now done when the EOR bucket is destroyed.
1426N/A This has the effect of delaying the logging until right after the last
797N/A of the response is sent; ap_core_output_filter() calls the access logger
797N/A indirectly when it destroys the EOR bucket. [Brian Pane]
1426N/A *) Rewrite of logresolve support utility: IPv6 addresses are now supported
1426N/A and the format of statistical output has changed. [Colm MacCarthaigh]
1426N/A *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
1426N/A *) Added new connection states for handler and write completion
4820N/A *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
1426N/A *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
1426N/A allowing string-valued client certificate attributes to be used for
1426N/A access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
1426N/A [Martin Kraemer, David Reid]
1426N/A *) ApacheMonitor: Fix Windows Vista detection. [Mladen Turk]
4820N/A *) mod_deflate: fix protocol handling in deflate input filter
1426N/A *) mod_proxy: fix buffer overflow issue
797N/A *) mod_filter: fix integer comparisons in dispatch rules
797N/A *) mod_filter: fix merging of ! and = in FilterChain
797N/A *) mod_cache: Let Cache-Control max-age set the expiration of the cached
797N/A representation if Expires is not set. [Justin Erenkrantz]
797N/A *) mod_disk_cache: Allow Vary'd responses to be refreshed properly.
797N/A *) mod_cache: Allow caching of requests with query arguments when
363N/A Cache-Control max-age is explicitly specified. [Justin Erenkrantz]
363N/A *) mod_proxy: Print the correct error message for erroneous configured
363N/A *) mod_so: Provide more helpful LoadModule feedback when an error occurs.
363N/A *) mod_alias: Accept path components (URL part) in Redirects. PR 35314.
363N/A *) mod_headers: Allow % at the end of a Header value. PR 36609.
363N/A [Nick Kew, Ruediger Pluem]
363N/A *) mod_cache: Use the same cache key throughout the whole request processing
363N/A to handle escaped URLs correctly. PR 41475. [Ruediger Pluem]
363N/A *) mod_cache: Add CacheIgnoreQueryString directive. PR 41484.
363N/A *) mod_cache: While serving a cached entity ensure that filters that have
797N/A been applied to this cached entity before saving it to the cache are not
797N/A applied again. PR 40090. [Ruediger Pluem]
797N/A *) mod_cache: Correctly cache objects whose URL query string has been
363N/A modified by mod_rewrite. PR 40805. [Ruediger Pluem]
363N/A *) mod_proxy_http: Change handling of ProxyErrorOverride such that
797N/A 3xx responses are no longer over-ridden (handling of 4xx and 5xx
797N/A responses is unchanged). PR 39245.
797N/A *) htdbm: Enable crypt support on platforms with crypt() but not
797N/A *) mod_ssl: initialize thread locks before initializing the hardware
363N/A acceleration library, so the latter can make use of the former.
363N/A *)
ab.c: Correct behavior of HTTP request headers sent by ab
699N/A in presence of -H command-line overrides. PR 31268, 26554.
363N/A *)
ab.c: The apr_port_t type is unsigned, but ab was using a
1426N/A signed format code in its reports. PR 42070.
1426N/A *) core: Correct a regression since
2.0.x in the handling of AllowOverride
4073N/A *) mod_proxy_http: Handle request bodies larger than 2 GB by converting
4073N/A the Content-Length header of the request correctly. PR 40883.
4337N/A *) mod_proxy: Fix some proxy setting inheritance problems (eg:
3817N/A *) Unix MPMs: Catch SIGFPE so that exception hooks and CoreDumpDirectory
5395N/A can work after that terminating signal.
*) Win32:
Makefile.win will now build with MS VC 8 (Visual Studio 2005)
including embedding the .manifest information into each binary.
Changes with Apache 2.2.4
*) mod_isapi: Correctly present SERVER_PORT_SECURE.
*) Allow htcacheclean, httxt2dbm, and fcgistarter to link
apr/apr-util statically like the older support programs.
*) 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.
*) 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.
*) 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.
*) 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]
*) mod_cgi and mod_cgid: Don't use apr_status_t error return
from input filters as HTTP return value from the handler.

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
directives. [Jeff Trawick]
*) 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.
*) 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.
*) mod_proxy: Don't try to use dead backend connection. PR 37770.
*) mod_proxy_balancer: Extract stickysession routing information contained as
parameter in the URL correctly. PR 40400.
*) 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:
*) 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
*) 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.
*) mod_isapi: Avoid double trailing slashes in HSE_REQ_MAP_URL_TO_PATH
support. Also corrects the slashes for Windows.
*) mod_isapi: Handle "HTTP/1.1 200 OK" style status lines correctly, the
token parser worked while the resulting length was misinterpreted.
*) 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.
*) mod_isapi: Ensure we walk through all the methods the developer may have
employed to report their HTTP status result code.

*) mod_echo: Fix precedence problem in if statement. PR 40658.
*) mod_mime_magic: Fix precedence problem in if statement. PR 40656.
*) 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
