  -Changes with Apache 2.0a5 since Apache 2.0a4
  +Changes with Apache 2.0a6
  +  *) Add support to Apache and APR for dsos on OS/390.  [Greg Ames]
  -  *) Perchild is serving pages after passing them to different child
  -     processes.  There are still a lot of bugs, but this does work.  I
  -     have made requests against the same installation of Apache, and had
  -     different servers use different user IDs to serve the responses.
  -     This change moves to using socketpair instead of an AF_UNIX socket.
  -     [Ryan Bloom]
  -  *) Perchild MPM still doesn't work perfectly, but it is serving pages.
  -     It can't seem to pass between child processes yet, but I think we
  -     are closer now than before.  This moves us back to using Unix
  -     Domain Sockets.  [Ryan Bloom]
  -  *) libapr functions and types renamed with apr_ prefix.
  -     #include "apr_compat.h" for 1.3.x backwards compat
  -     [Perl]
  -  *) Fix problems with APR sockaddr handling on Win32.  It didn't always
  -     return the right information on the local socket address.
  -     [Gregory Nicholls <>]
  -  *) ap_recv() on Win32: Set bytes-read to 0 on error.  
  -     [Gregory Nicholls <>]
  -  *) Add an option to not detach from the controlling terminal without
  -     going into single process mode.  This allows for much easier
  -     debugging of the process startup code. [Ryan Bloom]
  +  *) Add a chunking filter to Apache.  This brings us one step closer
  +     to removing BUFF. [Ryan Bloom]
  -  *) ab: don't use perror() to report the failure of an APR function.
  -     [Jeff Trawick]
  +  *) Apache 2.0 has been completely documented using Scandoc.  The
  +     docs can be generated by running 'make docs'.  [Ryan Bloom]
  -  *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
  -     scoreboard on graceful restarts.
  -     [Ryan Bloom]
  +  *) Add filtered I/O to Apache.  This is based on bucket brigades,
  +     Currently the buckets still use BUFF under the covers, but that
  +     should change quickly.  The only currently written filter is the
  +     core filter which just calls ap_bwrite.  [The Apache Group]
  -  *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
  -     An invalid ap_proc_t was passed to ap_create_process().
  -     [Jeff Trawick]
  +  *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
  +     built with thread support.  [Jeff Trawick]
  -  *) Allow modules to register filters.  Those filters are still
  -     never called, but this is a step in the right direction.
  -     [Ryan Bloom and Greg Stein]
  -  *) Register the mod_cgid daemon process for cleanup so that it is
  -     killed at termination if it does not die when the parent gets
  -     SIGTERM.  This change is to fix occasional problems where the
  -     process stays around.  Bugs in similar logic in mod_rewrite and
  -     mod_include were also fixed.  [Jeff Trawick]
  -  *) Fix a bug in the time handling.  Basically, we were imploding a time
  -     in ap_parseHTTPdate, but it had bogus data in the exploded time format.
  -     Namely, tm_usec and tm_gmtoff were not filled out.  ap_implode_time
  -     uses those two fields to adjust the time value.  Because of the HTTP
  -     spec, both of those values can be zero'ed out safely.  This fixes
  -     the bug correctly.  [Ryan Bloom]
  -  *) Fix a couple of place in the Windows code where the wrong error
  -     code was being returned. [Gregory Nicholls <>]
  -  *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
  -  *) Added the APR_EOL_STR macro for platform dependent differences in 
  -     logfiles and other raw text (such as all APR files).  Fixes logfiles
  -     not terminated with cr/lf sequences in Win32.  [William Rowe]
  -  *) Move all strings functions in APR to src/lib/apr/strings and create
  -     apr_strings.h for the prototypes. [Ryan Bloom]
  -  *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
  -     to repeat the syscall until we stop getting EINTR.  I noticed a
  -     related problem at termination (SIGTERM) on FreeBSD when using
  -     fcntl().  Apache 1.3 had these new loops too.  Also, make the flock() 
  -     implementation work properly with child init.  Previously, ap_lock()
  -     was essentially a no-op because all children were using different
  -     locks and thus nobody ever blocked.  [Jeff Trawick]
  -  *) The htdocs/ tree has been moved out of the CVS source tree into
  -     a separate area for easier development.  This has NO EFFECT on
  -     end-users or Apache installations.  [Ken Coar]
  -  *) Integrate the mod_dav module for WebDAV protocol handling. This
  -     adds the dav and dav_fs modules, the SDBM library, and additional
  -     XML handling utilities. [Greg Stein]
  -  *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
  -     [Greg Stein]
  -  *) Update the lib/expat-lite/ library (bring forward changes from
  -     the Apache 1.3 repository). [Greg Stein]
  -  *) If sizeof(long long) == sizeof(long), then prefer long in APR
  -  [Dave Hill <>]
  -  *) Add ap_sendfile for Tru64 Unix.  Also, add an error message for
  -     machines where sendfile is detected, but nobody has written ap_sendfile.
  -     [Dave Hill <>]
  -  *) Compile fixes in mod_mmap_static.  [Victor J. Orlikowski]
  -  *) ab would start up more connections than needed, then quit when the
  -     desired number were finished. Also fixed a logic error involving
  -     ab keepalives.  [Victor J. Orlikowski]
  -  *) WinNT: Implement non-blocking pipes with timeouts to communicate
  -     with CGIs. Apache 2.0a4 had non-blocking pipes but without 
  -     timeouts (i.e, if a timeout was specified, the pipe reverted to
  -     a full blocking pipe). Now the behaviour is more in line with
  -     Unix non-blocking pipes.
  -     [Bill Stoddard]
  -  *) WinNT: Implement accept socket reuse. Using mod_file_cache to
  -     cache open file handles along with accept socket reuse enables
  -     Apache 2.0 to serve non-keepalive requests for static files at
  -     3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
  -     and Apache 2.0 will serve almost 1200 rps on my system).
  -     [Bill Stoddard]
  -  *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
  -     supports two config directives, mmapfile (same behavious as
  -     mod_mmap_static) and cachefile. Use the cachefile directive
  -     to cache open file handles. This directive only works on systems
  -     that have implemented the ap_sendfile API. cachefile works today
  -     on Windows NT, but has not been tested on any flavors of Unix.
  -     [Bill Stoddard]
  -  *) Cleanup the configuration.  With the last few changes the
  -     configuration process automatically:
  -         inherits information about how to build from APR.  Allowing
  -         APR to inform Apache that it should or should not use -ldl
  -         Detects which mod_cgi should be used mod_cgi or mod_cgid,
  -         based on the threading model
  -         Apache calls APR's configure process before finishing it's
  -         configuration processing, allowing for more information flow
  -         between the two.
  -     [Ryan Bloom]
  -  *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
  -     with non-zero argument makes the socket non-blocking.  BeOS and
  -     OS/2 already worked this way.  [Jeff Trawick]
  +  *) Abort configuration if --with-layout was specified and there's
  +     no layout definition file.  [Ken Coar]
  -  *) ap_close() now calls ap_flush() for buffered files, so write
  -     operations work a whole lot better on buffered files.
  -     [Jeff Trawick]
  +  *) Add support for '--with-port=n' option to configure.  [Ken Coar]
  -  *) Fix error messages issued from MPMs which explain where to change
  -     compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
  -     [Greg Ames]
  -  *) ap_create_pipe() now leaves pipes in blocking state.  (This helps 
  -     reduce the number of syscalls on Unix.)  ap_set_pipe_timeout() is
  -     now the way that the blocking state of a pipe is manipulated.
  -     ap_block_pipe() is gone.  [Jeff Trawick]
  -  *) Correct the problem where the only local host name that the IP stack
  -     can discover are 'undotted' private names.  If no fully qualified
  -     domain name can be identified, the default ServerName will be set to
  -     the machine's IP address string. A warning is always provided if the
  -     ServerName not specified, but assumed.  Solves PR6215 [William Rowe]
  -  *) Repair problems with config file processing which caused segfault
  -     at init when virtual hosts were defined and which caused ServerName to
  -     be ignored when there was no valid DNS setup.  [Jeff Trawick]
  -  *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
  -  *) Add ap_sendfile implementation for AIX
  -     [Victor J. Orlikowski]
  -  *) Repair C++ compatibility in ap_config.h, apr_file_io.h, 
  -     apr_network_io.h, and apr_thread_proc.h.  
  -     [Tyler J. Brooks <>, Jeff Trawick]
  -  *) Bring the allocation and pool debugging code back into a working
  -     state.  This will need to be tested as so far it's only been used on
  -     BeOS. [David Reid]
  -  *) Change configuration command setup to be properly typesafe when in
  -     maintainer mode. Note that this requires a compiler that can initialise
  -     unions. [Ben Laurie]
  -  *) Turn on buffering for config file reads.  Part of this was to
  -     repair buffered I/O support in Unix and implement buffered
  -     ap_fgets() for all platforms.  [Brian Havard, Jeff Trawick]
  -  *) Win32: Fix problem where UTC offset was not being set correctly
  -     in the access log. Problem reported on news group by Jerry Baker.
  -     [Bill Stoddard]
  -  *) Fix segfault when reporting this type of syntax error:
  -     "</container> without matching <container> section", where
  -     container is VirtualHost or Directory or whatever.
  -     [Jeff Trawick]
  +  *) Add support for extension methods for the Allow response header
  +     field, and an API routine for accessing r->allowed and the
  +     list of extension methods in a unified manner.  [Ken Coar]
  +  *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
  +     [Rob Simonson <>]
  +  *) Get xlate builds working again.  The apr renaming in 2.0a5 broke
  +     APACHE_XLATE builds.  [Jeff Trawick]
  -  *) Prevent the source code for CGIs from being revealed when using
  -     mod_vhost_alias and the CGI directory is under the document root
  -     and a user makes a request like
  -     as reported in <>
  -     [Tony Finch]
  -  *) Add support for the new Beos NetwOrking Environment (BONE)
  -     [David Reid]
  -  *) xlate: ap_xlate_conv_buffer() now tells the caller when the
  -     final input char is incomplete; ap_bwrite_xlate() now handles
  -     incomplete final input chars.  [Jeff Trawick]
  -  *) Yet another update to saferead/halfduplex stuff -- need to ensure
  -     that a bhalfduplex call occurs before logging or else DNS and
  -     such can delay the last packet of the response.  [Dean Gaudet]
  -  *) Some syscall reduction in APR on unix -- don't seek when setting
  -     up an mmap; and don't fcntl() more than once per socket.
  -     [Dean Gaudet]
  -  *) When mod_cgid is started as root, the cgi daemon now switches 
  -     to the configured User/Group (like other httpd processes) 
  -     instead of continuing as root.  [Jeff Trawick]
  -  *) The prefork MPM now uses an APR lock for the accept() mutex.
  -     It has not been getting a lock at all recently.  httpd -V now 
  -     displays APR's selection of the lock mechanism instead of the 
  -     symbols previously respected by prefork.  [Jeff Trawick]
  -  *) Change the mmap() feature test to check only for existence.
  -     The previous check required features not used by Apache.
  -     [Greg Ames]
  -  *) Fix a couple of bugs in mod_cgid:  The cgi arguments were
  -     sometimes mangled.  The len parm to accept() was not 
  -     initialized, leading sometimes to an endless loop of failed
  -     accept() calls on OS/390 and anywhere else that failed the call
  -     if the len was negative.  Use <sys/un.h> for struct sockaddr_un
  -     instead of declaring it ourselves to fix a compilation problem
  -     on Solaris.  [Jeff Trawick]
  -  *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
  -  *) Fix zombie process problem with mod_cgi.  [Jeff Trawick]
  -  *) Port mod_mmap_static to 2.0.  Make it go faster.  [Greg Ames]
  -  *) Fix storage overlay when loading dsos.  Symptom: Apache dies at
  -     initialization if ALLOC_DEBUG is defined; no known symptom 
  -     otherwise.  [Jeff Trawick]
  -  *) Fix typo in configure script when checking for mod_so.  bash
  -     doesn't seem to have a problem but /bin/sh on Solaris does.
  -     Symptom: "./configure: test: unknown operator =="
  +  *) A configuration file parsing problem was fixed.  When the
  +     configuration file started with an IfModule/IfDefine container,
  +     only the last statement in the container would be retained.
        [Jeff Trawick]
  -  *) Rebind the Win32 NT and 9x services control into the MPM.  
  -     All console, WinNT SCM and Win9x pseudo-service control code is
  -     now wrapped within the WinNT MPM.
  -     [William Rowe]
  -  *) Make a copy of getenv("PATH") before storing for later use.  Some
  -     getenv() implementations use the same storage for successive calls.
  -     CGIs on OS/390 had a bad PATH due to this.  [Jeff Trawick]
  -  *) Server Tokens work in 2.0 again.  This also propogates the change
  -     to allow just the product name in the server string using
  -     [Ryan Bloom]
