Changes with Apache 2.1.0-dev

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

  *) Allow apachectl to perform status with links and elinks as well.
     [Justin Erenkrantz]

  *) Fix segfault which occurred when a section in an included file was
     not closed. PR 17093.  [André Malo]

  *) Extend the SetEnvIf directive to capture subexpressions of the
     matched value.  [André Malo]

  *) Updated mod_ldap and mod_auth_ldap to support the Novell LDAP SDK 
     and standardized the LDAP SSL support across the various LDAP SDKs.  
     Isolated the SSL functionality to mod_ldap rather than speading it 
     across mod_auth_ldap and mod_ldap.  Also added LDAPTrustedCA
     and LDAPTrustedCAType directives to mod_ldap to allow for a more 
     common method of specifying the SSL certificate.
     [Dave Ward, Brad Nicholes]

  *) mod_log_config change optional hook to return previous handler
     [Ian Holsman]

  *) Forward port of mod_actions' ability to handle arbitrary methods
     with the Script directive.  [André Malo]

  *) mod_cgi, mod_cgid, mod_ext_filter: Log errors when scripts cannot
     be started on Unix because of such problems as bad permissions,
     bad shebang line, etc.  [Jeff Trawick]

  *) Fix suexec compile error under SUNOS4, where strerror() doesn't
     exist. PR 5913, 9977.
     [Jonathan W Miner <Jonathan.W.Miner@lmco.com>]

  *) Let suexec send a message to stderr, if it failed or its policy
     was violated. This message appears in the error log and allows
     for easier debugging. PR 5381, 7638, 8255, 10773.  [André Malo]

  *) Modify buildconf to copy all required files into httpd's tree.
     [Thom May <thom@planetarytramp.net>]

  *) Allow mod_dav to do weak entity comparison functions.
     [Justin Erenkrantz]

  *) Fix If header parsing when a non-mod_dav lock token is passed to it.
     PR 16452.  [Justin Erenkrantz]

  *) mod_negotiation: Introduce "prefer-language" environment variable,
     which allows to influence the negotiation process on request basis
     to prefer a certain language.  [André Malo]

  *) Added AllowEncodedSlashes directive which permits request URIs
     to encode '/' as '%2f' and pass it to scripts in path-info without
     triggering the 'no encoded slashes anywhere' legacy rule.
     PR 543, 2389, 3581, 3589, 5687, 7066, 7865, 14639.  [Ken Coar]

  *) Move RFC 1413 ident requests from core to new module mod_ident.
     [André Malo]

  *) Add mod_authz_owner - a forward port of "Require file-owner"
     and "Require file-group", which was already present in version
     1.3.21.  [André Malo]

  *) Add mod_dav_lock - a generic subset of the DAV locking implementation.
     [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]

  *) 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]

  *) 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]

  *) 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]

  *) Rewrite of aaa modules to an authn/authz model.
     [Dirk-Willem van Gulik, Justin Erenkrantz]


  [Apache 2.1.0-dev includes those bug fixes and changes with the
   Apache 2.0.xx tree as documented, and except as noted, below.]

Changes with Apache 2.0.45

  *) mod_auth_digest no longer tries to guess AuthDigestDomain, if it's
     not specified. Now it assumes "/" as already documented. PR 16937.
     [André Malo]

  *) Try to log an error if a piped log program fails.  Try to
     restart a piped log program in more failure situations.  Fix an
     existing problem with error handling in piped_log_spawn().  Use
     new APR apr_proc_create() features to prevent Apache from starting
     on Unix* in most cases where a piped log program can be started,
     and add log messages for the other situations.  *Other platforms
     already failed Apache initialization if a piped log program
     couldn't be started.  PR 15761  [Jeff Trawick]

  *) Fix mod_cern_meta to not create empty metafiles when the
     metafile searched for does not exist.  PR 12353
     [Owen Rees <owen_rees@hp.com>]

  *) Introduce debugging symbols for Win32 release builds, both .pdb 
     and .dbg files (older debuggers and Dr. Watson-type utilities 
     on WinNT or Win9x don't support the newer .pdb flavor.)
     [Allen Edwards, William Rowe]

  *) Fix bug where 'Satisfy Any' without an AuthType lost all MIME
     information (and more). Related to PR 9076.  [André Malo]

  *) mod_file_cache: fix segfault serving mmaped cached files.
     [Bill Stoddard]

  *) mod_file_cache: fixed a segfault when multiple MMapFile directives
     were used.  PR 16313.  [Cliff Woolley]

  *) Fix a nasty segfault in mmap_bucket_setaside() caused by passing
     an incompatible pointer type to mmap_bucket_destroy(void*).
     [Gerard Eviston <geviston@bigpond.net.au>]

  *) Enable the -n name parameter on NetWare to allow the
     administrator to rename the Apache console screen
     [Brad Nicholes]
     
  *) Fixed piped access logs on Win32 by disabling OTHER_CHILD
     support by default in APR.  More development is required
     to deploy OTHER_CHILD on Win32.  [William Rowe]

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

  *) mod_rewrite: Allow "RewriteEngine Off" even if no "Options FollowSymlinks"
     (or SymlinksIfOwnermatch) is set. PR 12395.  [André Malo]

  *) apxs: Include any special APR ld flags when linking the DSO.
     This resolves problems on AIX when building a DSO with apxs+gcc.
     [Jeff Trawick]

  *) 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]
     
  *) Don't remove the Content-Length from responses in mod_proxy
     PR: 8677 [Brian Pane]

  *) Ensure LDAP version is set to v3 on every bind. PR 14235.
     [Sergey A. Lipnevich <sergeyli@pisem.net>]

  *) Fix mod_ldap to open an existing shared memory file should one
     already exist. PR 12757. [Scooter Morris <scooter@gene.com>, 
     Graham Leggett]

  *) Fix the ulimit command used by apachectl on Tru64.  PR 13609.
     [Joseph Senulis <Joseph.Senulis@dnr.state.wi.us>, Jeff Trawick]

  *) Change the ulimit command used by apachectl on AIX so that it
     works in all locales.  [Jeff Trawick]

  *) mod_ext_filter: Fix a problem building argument lists which 
     occasionally caused exec to fail.  PR 15491.  [Jeff Trawick]

Changes with Apache 2.0.44

  *) 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]
