Changes with Apache 2.1.0-dev

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

  *) Add another check for already compressed content in mod_deflate.
     PR 19913. [Tsuyoshi SASAMOTO <nazonazo@super.win.ne.jp>]

  *) Add a delete flag to htpasswd.
     [Thom May]

  *) Make mod_expires' ExpiresByType work properly, including for
     dynamically-generated documents.  [Ken Coar]

  *) Ensure that ssl-std.conf is generated at configure time, and switch
     to using the expanded config variables to work the same as
     httpd-std.conf PR 19611
     [Thom May]

  *) Fix a problem with namespace mappings being dropped in mod_dav_fs; 
     if any property values were set which defined namespaces these 
     came out mangled in the PROPFIND response.  PR 11637.
     [Amit Athavale <amit_athavale@persistent.co.in>]

  *) prefork MPM: Use the right permissions for the directory created 
     for gprof support.  [Jim Carlson <jcarlson@jnous.com>]

  *) Fix the inability to log errors like exec failure in
     mod_ext_filter/mod_cgi script children.  This was broken after 
     such children stopped inheriting the error log handle.  
     [Jeff Trawick]

  *) Fix a compile failure with recent OpenSSL and picky compilers
     (e.g., OpenSSL 0.9.7a and xlc_r on AIX).  [Jeff Trawick]

  *) Do not bypass output filters when redirecting subrequests internally.
     PR 17629.  [André Malo]

  *) OpenSSL headers should be included as "openssl/ssl.h", and not rely on
     the INCLUDE path to be defined properly.
     PR 11310. [Geoff Thrope <geoff@geoffthorpe.net>]

  *) Modify APACHE_CHECK_SSL_TOOLKIT to detect SSL-C. [Madhusudan Mathihalli]
     
  *) Replace the APACHE_CHECK_SSL_TOOLKIT method with a cleaner one, using
     autoconf tools (AC_CHECK_HEADER, AC_CHECK_LIB etc). 
     [Geoff Thorpe <geoff@geoffthorpe.net>]

  *) ssl session caching(shmht) : Fix a SEGV problem with SHMHT session
     caching. PR 17864.
     [Andreas Leimbacher <andreasl67@yahoo.de>, Madhusudan Mathihalli]

  *) change directive name from 'compressionlevel' to 'deflatecompressionlevel'
     [Ian Holsman, André Malo]

  *) mod_negotiation: quality values are now parsed independent from
     the current locale. level values are now really parsed as integers.
     PR 17564.  [André Malo]

  *) Added the WindowsSocketsWorkaround directive for Windows NT/2000/XP
     to work around problems with certain VPN and Firewall products that 
     have buggy AcceptEx implementations.
     [Allan Edwards w/ suggestions from Bill Stoddard & Bill Rowe]

  *) Extend mod_negotiation to evaluate the environment variables
     no-gzip and gzip-only-text/html the same way as mod_deflate does.
     [André Malo]

  *) mod_rewrite: Fix some problems reporting errors with mapping
     programs (RewriteMap prg:/something).  [Jeff Trawick]

  *) Fix mod_rewrite's handling of absolute URIs. The escaping routines
     now work scheme dependent and the query string will only be
     appended if supported by the particular scheme.  [André Malo]

  *) Return 413 if chunk-ext-header is too long rather than reading from
     the truncated line.  PR 15857.  [Justin Erenkrantz]

  *) If mod_mime_magic does not know the content-type, do not attempt to
     guess.  PR 16908.  [Andrew Gapon <agapon@telcordia.com>]

  *) Allow restart of httpd to occur even with syntax errors in the config
     file.  PR 16813.  [Justin Erenkrantz]

  *) Use APR_LAYOUT instead of APACHE_LAYOUT in configure.  PR 15679.
     [Justin Erenkrantz]

  *) Remove files on 'make distclean' that should be.  PR 15592.
     [Justin Erenkrantz]

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

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

  *) 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]

  *) 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]

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

  *) 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]

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

  *) 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 2.0.46

  *) Fixes for VPATH builds; copying special.mk and any future .mk files 
     from the source tree as well as the build tree (now creates a usable
     configuration for apxs), and eliminated redundant -I'nclude paths.
     [William Rowe]

  *) Code fixes, constness corrections and ssl_toolkit_compat.h updates
     for SSLC and OpenSSL toolkit compatibility.  Still work remains to
     be done to cripple features based on the limitations of RSA's binary 
     distribution of their SSL-C toolkit.
     [William Rowe, Madhusudan Mathihalli, Jeff Trawick]

  *) Linux 2.4+: If Apache is started as root and you code 
     CoreDumpDirectory, coredumps are enabled via the prctl() syscall.
     [Greg Ames]

  *) ap_get_mime_headers_core: allocate space for the trailing null
     when folding is in effect.
     PR 18170 [Peter Mayne <PeterMayne@SPAM_SUX.ap.spherion.com>]

  *) Fix --enable-mods-shared=most and other variants.  [Aaron Bannert]

  *) mod_log_config: Add the ability to log the id of the thread 
     processing the request via new %P formats.  [Jeff Trawick]

  *) Use appropriate language code for Czech (cs) and Traditional Chinese
     (zh-tw) in default config files. PR 9427.  [André Malo]

  *) mod_auth_ldap: Use generic whitespace character class when parsing
     "require" directives, instead of literal spaces only. PR 17135.
     [André Malo]

  *) Hook mod_rewrite's type checker before mod_mime's one. That way the
     RewriteRule [T=...] Flag should work as expected now. PR 19626.
     [André Malo]

  *) htpasswd: Check the processed file on validity. If a line is not empty
     and not a comment, it must contain at least one colon. Otherwise exit
     with error code 7. [Kris Verbeeck <Kris.Verbeeck@ubizen.com>, Thom May]

  *) Fix a problem that caused httpd to be linked with incorrect flags
     on some platforms when mod_so was enabled by default, breaking 
     DSOs on AIX.  PR 19012  [Jeff Trawick]

  *) By default, use the same CC and CPP with which APR was built.
     The user can override with CC and CPP environment variables.
     [Jeff Trawick]

  *) Fix ap_construct_url() so that it surrounds IPv6 literal address
     strings with [].  This fixes certain types of redirection.
