Changes with Apache 2.1.0-dev

  [Remove entries to the current 2.0 section below, when backported]

     [Justin Erenkrantz]

  *) Replace some of the mutex locking in the worker MPM with
     atomic operations for higher concurrency.  [Brian Pane]

  *) mod_deflate: Extend the DeflateFilterNote directive to
     allow accurate logging of the filter's in- and outstream.
     [André Malo]

  *) Use saner default config values for suexec. PR 15713.
     [Thom May <thom@planetarytramp.net>]

  *) Allow 'make depend' to work with non-GCC compilers.
     [Justin Erenkrantz]

  *) mod_cache: Fix PR 15113, a core dump in cache_in_filter when
     a redirect occurs. The code was passing a format string and
     integer to apr_pstrcat. Changed to apr_psprintf.
     [Paul J. Reder]

  *) Added character set support to mod_auth_LDAP to allow it to 
     convert extended characters used in the user ID to UTF-8 
     before authenticating against the LDAP directory. The new
     directive AuthLDAPCharsetConfig is used to specify the config
     file that contains the character set conversion table.
     [Brad Nicholes]
     
  *) Fix a bug where we leak fd's until the end of a keepalive 
     connection, which may result in:
       (24)Too many open files: file permissions deny server access
     especially on threaded servers.  [Greg Ames]

  *) If an httpd.conf has commented out AddModule directives, 
     apxs -i -a will add an un-commented AddModule directive for 
     the new module, which breaks the config.
     PR: 11212 [Joe Orton]

  *) Fix mod_proxy handling of filtered input bodies.  [Justin Erenkrantz]

  *) Don't remove the Content-Length from responses in mod_proxy

  *) Move the check of the Expect request header field after the hook
     for ap_post_read_request, since that is the only opportunity for
     modules to handle Expect extensions.  [Justin Erenkrantz]

  *) mod_autoindex: Bring forward the IndexOptions IgnoreCase option
     from Apache 1.3.  PR 14276
     [David Shane Holden <dpejesh@yahoo.com>, William Rowe]

  *) mod_mime: Workaround to prevent a segfault if r->filename=NULL
     [Brian Pane]

  *) Reorder the definitions for mod_ldap and mod_auth_ldap within
     config.m4 to make sure the parent mod_ldap is defined first.
     This ensures that mod_ldap comes before mod_auth_ldap in the
     httpd.conf file, which is necessary for mod_auth_ldap to load.
     PR 14256  [Graham Leggett]

  *) Fix the building of cgi command lines when the query string
     contains '='.  PR 13914  [Ville Skyttä <ville.skytta@iki.fi>,
     Jeff Trawick]

Changes with Apache 2.0.44

William A. Rowe Jr committed
  *) Rename CacheMaxStreamingBuffer to MCacheMaxStreamingBuffer. Move
     implementation of MCacheMaxStreamingBuffer from mod_cache to
     mod_mem_cache. MCacheMaxStreamingBuffer now defaults to the
     lesser of 100,000 bytes or MCacheMaxCacheObjectSize. This should 
     eliminate the need for explicitly coding MCacheMaxStreamingBuffer
     in most configurations. [Bill Stoddard]

  *) Replace APU_HAS_LDAPSSL_CLIENT_INIT with APU_HAS_LDAP_NETSCAPE_SSL
     as set by apr-util in util_ldap.c. This should allow mod_ldap
     to work with the Netscape/Mozilla LDAP library. [Øyvin Sømme
     <somme@oslo.westerngeco.slb.com>, Graham Leggett]

  *) Fix critical bug in new --enable-v4-mapped configure option
     implementation which broke IPv4 listening sockets on some
     systems.  [hiroyuki hanai <hanai@imgsrc.co.jp>]

  *) mod_setenvif: Fix BrowserMatchNoCase support for non-regex
     patterns [André Malo <nd@perlig.de>]

  *) Add version string to provider API.  [Justin Erenkrantz]

  *) build: './configure && make' now works without an in-tree
     apr and apr-util. [Wilfredo Sanchez]

  *) mod_negotiation: Set the appropriate mime response headers
     (Content-Type, charset, Content-Language and Content-Encoding)
     for negotated type-map "Body:" responses (such as the error
     pages.)  [André Malo <nd@perlig.de>]

  *) mod_log_config: Allow '%%' escaping in CustomLog format
     strings to insert a literal, single '%'.
     [André Malo <nd@perlig.de>]

  *) mod_autoindex: AddDescription directives for directories
     now work as in Apache 1.3, where no trailing '/' is
     specified on the directory name.  Previously, the trailing
     '/' *had* to be specified, which was incompatible with
     Apache 1.3.  PR 7990  [Jeff Trawick]

  *) Fix for PR 14556. The expiry calculations in mod_cache were
     trying to perform "now + ((date - lastmod) * factor)" where
     date == lastmod resulting in "now + 0". The code now follows
     the else path (using the default expiration) if date is
     equal to lastmod. [rx@armstrike.com (Sergey), Paul J. Reder]

  *) Use AP_DECLARE in the debug versions of ap_strXXX in case the
     default calling convention is not the same as the one used by
     AP_DECLARE.  [Juan Rivera <Juan.Rivera@citrix.com>]

  *) mod_cache: Don't cache response header fields designated
     as hop-by-hop headers in HTTP/1.1 (RFC 2616 Section 13.5.1).
     [Estrade Matthieu <estrade-m@ifrance.com>, Brian Pane]

  *) mod_cgid: Handle environment variables containing newlines.
     PR 14550  [Piotr Czejkowski <apache@czarny.eu.org>, Jeff
     Trawick]

  *) Move mod_ext_filter out of experimental and into filters.
     [Jeff Trawick]

  *) Fixed a memory leak in mod_deflate with dynamic content.
     PR 14321  [Ken Franken <kfranken@decisionmark.com>]

  *) Add --[enable|disable]-v4-mapped configure option to control
     whether or not Apache expects to handle IPv4 connections
     on IPv6 listening sockets.  Either setting will work on 
     systems with the IPV6_V6ONLY socket option.  --enable-v4-mapped
     must be used on systems that always allow IPv4 connections on
     IPv6 listening sockets.  PR 14037 (Bugzilla), PR 7492 (Gnats)
     [Jeff Trawick]

  *) This fixes a problem where the underlying cache code
     indicated that there was one more element on the cache
     than there actually was. This happened since element 0
     exists but is not used. This code allocates the correct
     number of useable elements and reports the number of
     actually used elements. The previous code only allowed
     MCacheMaxObjectCount-1 objects to be stored in the
     cache. [Paul J. Reder]

  *) mod_setenvif: Add SERVER_ADDR special keyword to allow
     envariable setting according to the server IP address
     which received the request.  [Ken Coar]

  *) mod_cgid: Terminate CGI scripts when the client connection 
     drops.  PR 8388  [Jeff Trawick]

  *) Rearrange OpenSSL engine initialization to support RAND 
     redirection on crypto accelerator. 
     [Frederic DONNAT <frederic.donnat@zencod.com>]

  *) Always emit Vary header if mod_deflate is involved in the
     request.  [Andre Malo <nd@perlig.de>]

  *) mod_isapi: Stop unsetting the 'empty' query string result with
     a NULL argument in ecb->lpszQueryString, eliminating segfaults
     for some ISAPI modules.  PR 14399
     [Detlev Vendt <detlev.vendt@brillit.de>]

  *) mod_isapi: Fix an issue where the HSE_REQ_DONE_WITH_SESSION
     notification is received before the HttpExtensionProc() returns 
     HSE_STATUS_PENDING.  This only affected isapi .dll's configured 
     with the ISAPIFakeAsync on directive.  PR 11918
     [John DeSetto <jdesetto@radiantsystems.com>, William Rowe]

  *) mod_isapi: Fix the issue where all results from mod_isapi would
     run through the core die handler resulting in invalid responses
     or access log entries.  PR 10216 [William Rowe]

  *) Improves the user friendliness of the CacheRoot processing
     over my last pass. This version avoids the pool allocations
     but doesn't avoid all of the runtime checks. It no longer
     terminates during post-config processing. An error is logged
     once per worker, indicating that the CacheRoot needs to be set.
     [Paul J. Reder]

  *) Fix a bug in which mod_proxy sent an invalid Content-Length
     when a proxied URL was invoked as a server-side include within
     a page generated in response to a form POST.  [Brian Pane]
