  -Changes with Apache 2.0a4 since Apache 2.0a3
  -  *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
  -     won't need to call it.  [Greg Ames, Jeff Trawick]
  -  *) Move pre_config hook call to between configuration read and config
  -     tree walk.  This allows all modules to implement pre_config hooks
  -     and know that they will be called at an appropriate time.
  -     [Ryan Bloom] 
  -  *) mod_cgi, mod_cgid: Make ScriptLog directive work again.  
  -     [Jeff Trawick]
  +Changes with Apache 2.0a5 since Apache 2.0a4
  -  *) Add pre-config hooks back to all modules.
  +  *) 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]
  -  *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
  -     ContentDigest enabled and we can't/don't mmap the file. 
  -     [Jeff Trawick]
  -  *) We now report the correct line number for syntax errors in config
  -     files.  [Ryan Bloom, Greg Stein, Jeff Trawick]
  -  *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
  -     related bugs, and changed shmem/locking to use apr API. Shared-mem
  -     is currently disabled, however, because of problems with graceful
  -     restarts. [Ronald Tschalär]
  -  *) Fix corruption of IFS variable in --with-module= handling.  
  -     Depending on the user's shell or customization thereof, there 
  -     would be errors generating ap_config_auto.h later in the configure
  -     procedure.  [Jeff Trawick]
  -  *) mod_cgi: Restore logging of stderr from child process when ScriptLog 
  -     isn't used (as in 1.3), except that on Unix it is now logged via 
  -     ap_log_rerror() instead of by the child having STDERR_FILENO refer
  -     to the error log.  [Greg Ames, Jeff Trawick]
  -  *) Add '-D' argument processing for run time configuration defines.
  -     [William Rowe]
  +  *) 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]
  -  *) Organize http_main.c as independent code, such that no code or
  -     global data is exported from it.  WIN32 will dynamically link it
  -     to the server core, so this will prevent mutual dependency.
  -     [William Rowe]
  -  *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
  -     and APR_VAR_EXPORT to correctly resolve apr functions and globals.
  -     [William Rowe]
  -  *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
  -     [William Rowe, Jan Just Keijser <>]
  -  *) Add mod_charset_lite for configuring character set translation.
  +  *) ab: don't use perror() to report the failure of an APR function.
        [Jeff Trawick]
  -  *) Add '-n' option to htpasswd to make it print its user:pw record
  -     on stdout rather than having to frob a text file.  [Ken Coar]
  -  *) Fix saferead.  Basically, we flush the output buffer if a read on the
  -     input will block.
  +  *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
  +     scoreboard on graceful restarts.
        [Ryan Bloom]
  -  *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
  -     a conversion is single-byte only. [Jeff Trawick]
  -  *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
  -     the BeOS 5.0 documentation says that shutdown doesn't work yet.
  -     [Roy Fielding]
  -  *) Fix some minor errors where pid was being manipulated as an int
  -     instead of the portable pid_t.  [Roy Fielding]
  -  *) Fix some error log prints that were printing the pointer to a
  -     structure rather than the pid within the structure.
  -     [Jeff Trawick, Roy Fielding]
  -  *) ab: Fix a command-line processing bug; track bad headers in 
  -     err_response; support reading headers up to 2K. 
  -     [Ask Bjoern Hansen <>]
  -  *) Fix ap_resolve_env() so that it handles new function added in a prior
  -     alpha (see "Added the capability to do ${ENVVAR} constructs in the
  -     config file.") as well as the constructs used by mod_rewrite.
  -     [Paul Reder <>]
  -  *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
  -  *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
  -     APR to perform translation, instead of accessing the hard-coded tables
  -     in 1.3's ebcdic.c. [Jeff Trawick]
  -  *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing. 
  +  *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
  +     An invalid ap_proc_t was passed to ap_create_process().
        [Jeff Trawick]
  -  *) Add the ability to hook into the config file reading phase.  Basically
  -     if a directive is specified EXEC_ON_READ, then when that directive is
  -     read from the config file, the assocaited function is executed.  This
  -     should only be used for those directives that must muck with HOW the
  -     server INTERPRETS the config.  This should not be used for directives
  -     that re-order or replace items in the config tree.  Those changes should
  -     be made in the pre-config step.
  +  *) 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]
  -  *) Add mod_example to the build system.
  -     [Tony Finch]
  -  *) APR: Add ap_xlate_conv_byte() to convert one char between single-
  -     byte character sets. [Jeff Trawick]
  +  *) 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]
  -  *) Pick up various EBCDIC fixes from 1.3 (from Martin
  -     Kraemer and Oliver Reh originally according to the change log).
  +  *) ap_close() now calls ap_flush() for buffered files, so write
  +     operations work a whole lot better on buffered files.
        [Jeff Trawick]
  -  *) Fix a couple of problems in RFC1413 support (controlled by the
  -     IdentityCheck directive).  Apache did not build the request string
  -     properly and more importantly Apache would loop forever if the 
  -     would-be ident server dropped the connection before sending a
  -     properly terminated response. [Jeff Trawick]
  -  *) apxs works in 2.0.
  -     [Ryan Bloom]
  -  *) Reliable piped logs work in 2.0.
  -     [Ryan Bloom]
  +  *) 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]
  -  *) Introduce a hash table implementation into APR to be used for
  -     replacing tables and other random data structures in Apache.
  +  *) 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 some more error reporting to htpasswd in the case of problems
  -     generating or accessing the temporary file.  Also, pass in a
  -     buffer if the implementation knows how to use it (i.e., if L_tmpnam
  -     is defined).  [Ken Coar]
  -  *) Configure creates config.nice now containing your configure
  -     options. Syntax: ./config.nice [--more-options]
  -     [Sascha Schumann]
  -  *) Fix various return code problems in APR on Win32.  For most of
  -     these, APR was returning APR_EEXIST instead of GetLastError()/
  -     WSAGetLastError().  [Jeff Trawick]
  +  *) Add support for the new Beos NetwOrking Environment (BONE)
  +     [David Reid]
  -  *) Make piped logs work again in version 2.0
  -     [Ryan Bloom]
  -  *) Add VPATH support to UNIX build system of Apache and APR.
  -     [Sascha Schumann]
  -  *) Fix ap_tokenize_to_argv to respect the const arguments that are
  -     passed to it.
  -     [Ryan Bloom]
  -  *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
  -     Patch submitted to author.
  -     [Sascha Schumann]
  -  *) Fix mm configuration on Solaris 8 x86 and OS/390.  Don't require
  -     /sbin in PATH on FreeBSD (all submitted to rse previously) 
  +  *) 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 =="
        [Jeff Trawick]
  -  *) Fix building Pthread-based MPMs on OpenBSD
  -     [Sascha Schumann] PR#26
  -  *) Fix ap_readdir() problem on systems where d_name[] field in
  -     struct dirent is declared with only one byte.  (This problem only 
  -     affected multithreaded builds.)  This caused a segfault during
  -     pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at 
  -     least). [Jeff Trawick]
  -  *) Fix some make-portability problems on at least Tru64, Irix
  -     and UnixWare.
  -     [Sascha Schumann] PR#18, PR#39
  -  *) Add ap_sigwait() to support old-style sigwait() on systems
  -     like OS/390 and UnixWare.
  -     [Sascha Schumann] 
  -  *) Add POSIX-thread flags for more platforms.
  -     [Sascha Schumann]
  -  *) Fix some minor bugs in ap_strerror().  Teach ap_strerror()
  -     (on Unix, at least) to handle resolver errors.  Fix a bug in
  -     the definition of APR_ENOMEM so that ap_strerror() can spit
  -     out the correct error message for it.
  -     [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]
