579 parameters to the environment. Improve portability to
580 EBCDIC machines by using apr_toupper(). [Martin Kraemer]
582 *) mod_ldap, mod_authnzldap: Add support for nested groups (i.e. the ability
583 to authorize an authenticated user via a "require ldap-group X" directive
584 where the user is not in group X, but is in a subgroup contained in X.
585 PR 42891 [Paul J. Reder]
587 *) mod_ssl: Add support for caching SSL Sessions in memcached. [Paul Querna]
589 *) mod_ldap: Fix the search limit parameter to ldap_search_ext_s()
590 for SDKs that define LDAP_NO_LIMIT to something other than -1.
591 [David Jones <oscaremma gmail.com>]
593 *) apxs: Enhance -q flag to print all known variables and their values
594 when invoked without variable name(s).
595 [William Rowe, Sander Temme]
597 *) apxs: Eliminate run-time check for mod_so. PR 40653.
598 [David M. Lee <dmlee crossroads.com>]
600 *) beos MPM: Create pmain pool and run modules' child_init hooks when
601 entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
604 *) netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
605 cleanups registered in modules' child_init hooks are performed.
608 *) mod_dbd: Stash DBD connections in request_config of initial request
609 only, or else sub-requests and internal redirections may cause
610 entire DBD pool to be stashed in a single HTTP request. [Chris Darroch]
612 *) Fix issue which could cause error messages to be written to access logs
613 on Win32. PR 40476. [Tom Donovan <Tom.Donovan acm.org>]
615 *) The LockFile directive, which specifies the location of
616 the accept() mutex lockfile, is deprecated. Instead, the
617 AcceptMutex directive now takes an optional lockfile
618 location parameter, ala SSLMutex. [Jim Jagielski]
620 *) mod_authn_dbd: Export any additional columns queried in the SQL select
621 into the environment with the name AUTHENTICATE_<COLUMN>. This brings
622 mod_authn_dbd behaviour in line with mod_authnz_ldap. [Graham Leggett]
624 *) mod_dbd: Key the storage of prepared statements on the hex string
625 value of server_rec, rather than the server name, as the server name
626 may change (eg when the server name is set) at any time, causing
627 weird behaviour in modules dependent on mod_dbd. [Graham Leggett]
629 *) mod_proxy_fcgi: Added win32 build. [Mladen Turk]
631 *) sendfile_nonblocking() takes the _brigade_ as an argument, gets
632 the first bucket from the brigade, finds it not to be a FILE
633 bucket and barfs. The fix is to pass a bucket rather than a brigade.
634 [Niklas Edmundsson <nikke acc.umu.se>]
636 *) mod_rewrite: support rewritemap by SQL query [Nick Kew]
638 *) ap_get_server_version() has been removed. Third-party modules must
639 now use ap_get_server_banner() or ap_get_server_description().
642 *) All MPMs: Introduce a check_config phase between pre_config and
643 open_logs, to allow modules to review interdependent configuration
644 directive values and adjust them while messages can still be logged
645 to the console. Handle relevant MPM directives during this phase
646 and format messages for both the console and the error log, as
647 appropriate. [Chris Darroch]
649 *) mod_proxy: don't URLencode tilde in path component
650 [Stijn Hoop <stijn sandcat.nl>]
652 *) mpm_winnt: Fix return values from wait_for_many_objects.
653 The return value is index to the signaled thread in the
654 creted_threads array. We can not use WAIT_TIMEOUT because
655 his value is defined as 258, thus limiting the MaxThreads
656 to that value. [Mladen Turk]
658 *) core: Do not allow internal redirects like the DirectoryIndex of mod_dir
659 to circumvent the symbolic link checks imposed by FollowSymLinks and
660 SymLinksIfOwnerMatch. [Nick Kew, Ruediger Pluem, William Rowe]
662 *) New SSLLogLevelDebugDump [ None (default) | IO (not bytes) | Bytes ]
663 configures the I/O Dump of SSL traffic, when LogLevel is set to Debug.
664 The default is none as this is far greater debugging resolution than
665 the typical administrator is prepared to untangle. [William Rowe]
667 *) mod_disk_cache: If possible, check if the size of an object to cache is
668 within the configured boundaries before actually saving data.
669 [Niklas Edmundsson <nikke acc.umu.se>]
671 *) mod_disk_cache: Delete temporary files if they cannot be renamed to their
672 final name. [Davi Arnaut <davi haxent.com.br>]
674 *) Worker and event MPMs: Remove improper scoreboard updates which were
675 performed in the event of a fork() failure. [Chris Darroch]
677 *) Add support for fcgi:// proxies to mod_rewrite.
678 [Markus Schiegl <ms schiegl.com>]
680 *) Remove incorrect comments from scoreboard.h regarding conditional
681 loading of worker_score structure with mod_status, and remove unused
682 definitions relating to old life_status field.
683 [Chris Darroch <chrisd pearsoncmg.com>]
685 *) Remove allocation of memory for unused array of lb_score pointers
686 in ap_init_scoreboard(). [Chris Darroch <chrisd pearsoncmg.com>]
688 *) Add mod_proxy_fcgi, a FastCGI back end for mod_proxy.
689 [Garrett Rooney, Jim Jagielski, Paul Querna]
691 *) Event MPM: Fill in the scoreboard's tid field. PR 38736.
692 [Chris Darroch <chrisd pearsoncmg.com>]
694 *) mod_charset_lite: Remove Content-Length when output filter can
695 invalidate it. Warn when input filter can invalidate it.
698 *) Authz: Add the new module mod_authn_core that will provide common
699 authn directives such as 'AuthType', 'AuthName'. Move the directives
700 'AuthType' and 'AuthName' out of the core module and merge mod_authz_alias
701 into mod_authn_core. [Brad Nicholes]
703 *) Authz: Move the directives 'Order', 'Allow', 'Deny' and 'Satisfy'
704 into the new module mod_access_compat which can be loaded to provide
705 support for these directives.
708 *) Authz: Move the 'Require' directive from the core module as well as
709 add the directives '<SatisfyAll>', '<SatisfyOne>', '<RequireAlias>'
710 and 'Reject' to mod_authz_core. The new directives introduce 'AND/OR'
711 logic into the authorization processing. [Brad Nicholes]
713 *) Authz: Add the new module mod_authz_core which acts as the
714 authorization provider vector and contains common authz
715 directives. [Brad Nicholes]
717 *) Authz: Renamed mod_authz_dbm authz providers from 'group' and
718 'file-group' to 'dbm-group' and 'dbm-file-group'. [Brad Nicholes]
720 *) Authz: Added the new authz providers 'env', 'ip', 'host', 'all' to handle
721 host-based access control provided by mod_authz_host and invoked
722 through the 'Require' directive. [Brad Nicholes]
724 *) Authz: Convert all of the authz modules from hook based to
725 provider based. [Brad Nicholes]
727 *) mod_cache: Add CacheMinExpire directive to set the minimum time in
728 seconds to cache a document.
729 [Brian Akins <brian.akins turner.com>, Ruediger Pluem]
731 *) mod_authz_dbd: SQL authz with Login/Session support [Nick Kew]
733 *) Fix typo in ProxyStatus syntax error message.
734 [Christophe Jaillet <christophe.jaillet wanadoo.fr>]
736 *) Asynchronous write completion for the Event MPM. [Brian Pane]
738 *) Added an End-Of-Request bucket type. The logging of a request and
739 the freeing of its pool are now done when the EOR bucket is destroyed.
740 This has the effect of delaying the logging until right after the last
741 of the response is sent; ap_core_output_filter() calls the access logger
742 indirectly when it destroys the EOR bucket. [Brian Pane]
744 *) Rewrite of logresolve support utility: IPv6 addresses are now supported
745 and the format of statistical output has changed. [Colm MacCarthaigh]
747 *) Rewrite of ap_coreoutput_filter to do nonblocking writes [Brian Pane]
749 *) Added new connection states for handler and write completion
752 *) mod_cgid: Refuse to work on Solaris 10 due to OS bugs. PR 34264.
755 *) Teach mod_ssl to use arbitrary OIDs in an SSLRequire directive,
756 allowing string-valued client certificate attributes to be used for
757 access control, as in: SSLRequire "value" in OID("1.3.6.1.4.1.18060.1")
