Changes with Apache 2.0.37

  *) Rewrite mod_cgi's input handling to use brigades and input
     filters.  [Justin Erenkrantz]

  *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
     body.  [Justin Erenkrantz]
    
  *) NetWare: Piping log entries through RotateLogs using the 
     CustomLogs directive is finally supported now that we have 
	 the pipes and spawning functionality working.
     [Brad Nicholes]

  *) Detect overflow when reading the hex bytes forming a chunk line.
     [Aaron Bannert]

  *) Allow RewriteMap prg:'s to take command-line arguments.  PR 8464.
     [James Tait <JTait@wyrddreams.demon.co.uk>]

  *) Correctly return 413 when an invalid chunk size is given on
     input.  Also modify ap_discard_request_body to not do anything
     on sub-requests or when the connection will be dropped.
     [Justin Erenkrantz]

  *) Fix the TIME_* SSL var lookups to be threadsafe.  PR 9469.
     [Cliff Woolley]

  *) Ensure that apr_brigade_write() flushes in all of the cases that
     it should to avoid conditions in some modules that could cause
     large amounts of data to be buffered.  [Cliff Woolley]

  *) Fix problem where mod_cache/mod_disk_cache was incorrectly
     stripping the content_type from cached responses.
     [Bill Stoddard]

  *) apachectl passes through any httpd options.  Note: apachectl
     should be used in preference to httpd since it ensures that any
     appropriate environment variables have been set up.
     [Jeff Trawick]

  *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.
     PR 7810  [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]

  *) Fix suexec execution of CGI scripts from mod_include.
     PR 7791, 8291  [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]

  *) Fix segfaults at startup on some platforms when mod_auth_digest,
     mod_suexec, or mod_ssl were used as DSO's due to the way they
     were tracking the current init phase since DSO's get completely
     unloaded and reloaded between phases.  PR 9413.
     [Tsuyoshi Sasamoto <nazonazo@super.win.ne.jp>, Brad Nicholes]

  *) Fix mod_include's handling of regular expressions in
     "<!--#if" directives [Julius Gawlas <julius_gawlas@hp.com>]

  *) Fix the worker MPM deadlock problem  [Brian Pane]

  *) Modify the module documentation to allow for translations.
     [Yoshiki Hayashi, Joshua Slive]

  *) Fix a file permissions problem which prevented mod_disk_cache
     from working on Unix.  [Jeff Trawick]

  *) Add "-k start|restart|graceful|stop" support to httpd for the Unix 
     MPMs.  These have semantics very similar to the old apachectl 
     commands of the same name.  [Justin Erenkrantz, Jeff Trawick]
  *) Make sure that the runtime dir is created by make install.
     PR 9233.  [Jeff Trawick]

  *) Fix an unusual set of ./configure arguments that could cause
     mod_http to be built as a DSO, which it currently doesn't
     support.  PR 9244.
     [Cliff Woolley, Robin Johnson <robbat2@orbis-terrarum.net>]

  *) Win32: Fix bug in apr_sendfile() that caused incorrect operation
     of the %X, %b and %B logformat options. PR 8253, 8996.

  *) If content-encoding is already present, do not run deflate (PR 9222)
     [Kazuhisa ASADA <kaz@asada.sytes.net>]

  *) The APLOG_NOERRNO flag to ap_log_[r]error() is now deprecated.
     It is currently ignored and it will be removed in a future release
     of Apache.  [Jeff Trawick]

  *) Removed documentation references to the no-longer-supported
     "make certificate" feature of mod_ssl for Apache 1.3.x.  Test
     certificates, if truly desired, can be generated using openssl
     commands.  PR 8724.  [Cliff Woolley]

  *) Remove SSLLog and SSLLogLevel directives in favor of having
     mod_ssl use the standard ErrorLog directives.  [Justin Erenkrantz]

  *) OS/390: LIBPATH no longer has to be manually uncommented in
     envvars to get apachectl to set up httpd properly.  [Jeff Trawick]

  *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
     may now be specified to the <File/Directory > container, rather
     than by vhost.  [William Rowe]

  *) mod_isapi: Experimental support for faux async support for ISAPI
     modules.  [William Rowe]

  *) mod_isapi: Major refactoring of the code to rely on apr internals
     rather than MS APIs (using our own mod_isapi.h headers for ISAPI
     symbol definitions.)  [William Rowe]

  *) mod_isapi: Fixed the return string length from GetServerVariable
     callback, it was not including the trailing null in the consumed
     buffer size.  This was particularly bad for Delphi 6.0 users.
     PR 8934  [Sebastian Hantsch <sebastian.hantsch@gmx.de>]

  *) Fixed Win32 builds for Microsoft VisualStudio 7.0 (.net).
     [William Rowe]

  *) Make apxs look in the correct directory for envvars.  It was
     broken when sbindir != bindir.  PR 8869
     [Andreas Sundström <sunkan@zappa.cx>]
  
  *) Fix mod_deflate corruption when using multiple buckets.  PR 9014.
     [Asada Kazuhisa <kaz@asada.sytes.net>]

  *) Performance enhancements for access logger when using
     default timestamp formatting  [Brian Pane]

  *) Added EnableMMAP config directive to enable the server
     administrator to disable memory-mapping of delivered files
     on a per-directory basis.  [Brian Pane]

  *) Performance enhancements for mod_setenvif  [Brian Pane]

  *) Fix a mod_ssl build problem on OS/390.  [Jeff Trawick]

  *) Fixed If-Modified-Since on Win32, which would give false positives
     because of the sub-second resolution of file timestamps on that
     platform.  [Cliff Woolley]

  *) Reverse the hook ordering for mod_userdir and mod_alias so
     that Alias/ScriptAlias will override Userdir.  PR 8841
     [Joshua Slive]

  *) Move mod_deflate out of experimental and into filters.
     [Justin Erenkrantz]

  *) Get proxy CONNECT basically working.  [Jeff Trawick]

  *) Fix mod_rewrite hang when APR uses SysV Semaphores and
     RewriteLogLevel is set to anything other than 0.  PR: 8143
     [Aaron Bannert, Cliff Woolley]

  *) Fix byterange requests from returning 416 when using dynamic data
     (such as filters like mod_include).  [Justin Erenkrantz]

  *) Allow mod_rewrite's set of "int:" internal RewriteMap functions
     to be extended by third-party modules via an optional function.
     [Tahiry Ramanamampanoharana <nomentsoa@hotmail.com>, Cliff Woolley]

  *) Fix mod_include expression parser's handling of unquoted strings
     followed immediately by a closing paren.  PR 8462.  [Brian Pane]

  *) Remove autom4te.cache in 'make distclean'.
     [Thom May <thom@planetarytramp.net>]

  *) Fix generated httpd.conf to respect layout for LoadModule lines.
     PR 8170.  [Thom May <thom@planetarytramp.net>]

  *) Win32: During a graceful restart, threads in the new process
     were accessing scoreboard slots still in use by active threads in 
     the the old process. [Bill Stoddard]

  *) Close sockets on worker MPM when doing a graceless restart.
     [Aaron Bannert]

  *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
     as the session id context rather that a MD5 hash of that vhost ID,
     because it caused very long vhost id's to be unusable with mod_ssl.
     PR 8572.  [Cliff Woolley]

  *) Fix the link to the description of the CoredumpDirectory 
     directive in the server-wide document.  PR 8643.  [Jeff Trawick]

  *) Fixed SHMCB session caching.  [Aaron Bannert, Cliff Woolley]

  *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
     - Avoid SIGBUS on sparc machines with SHMCB session caches
     - Allow whitespace between the pipe and the name of the
     program in SSLLog "| /path/to/program".  [Cliff Woolley]
