CHANGES

     (such as <Files a*b> not working).  [Dean Gaudet] PR#1817

  *) Removed bogus "dist.tar" target from Makefile.tmpl and make sure
     backup files are removed on "clean" target [Ralf S. Engelschall]

  *) PORT: Add -lm to LIBS for HPUX.  [Dean Gaudet] PR#1639

  *) Various errors from select() and accept() in child_main() would
     result in an infinite loop.  It seems these two tickle kernel
     or library bugs occasionally, and result in log spammage and
     a generally bad scene.  Now the child exits immediately,
     which seems to be a good workaround.
     [Dean Gaudet] PR#1747, 1107, 588, 1787, 987, 588

  *) Cleaned up some race conditions in unix child_main during
     initialization. [Dean Gaudet]

  *) SECURITY: "UserDir /abspath" without a * in the path would allow
     remote users to access "/~.." and bypass access restrictions
     (but note /~../.. was handled properly).
     [Lauri Jesmin <jesmin@ut.ee>] PR#1701

  *) API: os_is_path_absolute() now takes a const char * instead of a char *.
     [Dean Gaudet]

Changes with Apache 1.3b5

  *) Source file dependencies in Makefile.tmpl files throughout the
     source tree were updated to accurately reflect reality.
     [Dean Gaudet]

  *) Preserve the content encoding given by the AddEncoding directive
     when the client doesn't otherwise specify an encoding.
     [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>]

  *) Sort out problems with canonical filename handling happening too late.
     [Dean Gaudet, Ben Laurie]

Changes with Apache 1.3b4

  *) The module structure was modified to include a *dynamic_load_handle
     in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
     has been bumped accordingly.  [Paul Sutton]

  *) All BrowserMatch directives mentioned in
     htdocs/manual/known_client_problems.html are in the default
     configuration files.  [Lars Eilebrecht]

  *) MiNT port update. [Jan Paul Schmidt]

  *) HTTP/1.1 requires x-gzip and gzip encodings be treated
     equivalent, similarly for x-compress and compress.  Apache
     now ignores a leading x- when comparing encodings.  It also
     preserves the encoding the client requests (for example if
     it requests x-gzip, then Apache will respond with x-gzip
     in the Content-Encoding header).
     [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772

  *) Fix a memory leak on keep-alive connections.  [Igor Tatarinov]

  *) Added mod_so module to support dynamic loading of modules on Unix
     (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
     instead of AddModule in Configuration to build shared modules
     [Sameer Parekh, Paul Sutton]

  *) Minor cleanups to r->finfo handling in some modules.
     [Dean Gaudet]

  *) Abstract read()/write() to ap_read()/ap_write().
     Makes it easier to add other types of IO code such as SFIO.
     [Randy Terbush]

  *) API: Generalize default_port manipulations to make support of
     different protocols easier. [Ben Laurie, Randy Terbush]

  *) There are many cases where users do not want Apache to form
     self-referential urls using the "canonical" ServerName and Port.
     The new UseCanonicalName directive (default on), if set to off
     will cause Apache to use the client-supplied hostname and port.
     API: Part of this change required a change to the construct_url()
     prototype; and the addition of get_server_name() and
     get_server_port().
     [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
     PR#315, 459, 485, 1433

  *) Yet another rearrangement of the source tree.. now all the common
     header files are in the src/include directory.  The -Imain -Iap
     references in Makefiles have been changed to the simpler -Iinclude
     instead.  In addition to simplifying the build a little bit, this
     also makes it clear when a module is referencing something in a
     other than kosher manner (e.g., the proxy including mod_mime.h).
     Module-private header files (the proxy, mod_mime, the regex library,
     and mod_rewrite) have not been moved to src/include; nor have
     the OS-abstraction files.  [Ken Coar]

  *) Fix a bug where r->hostname didn't have the :port stripped
     from it.  [Dean Gaudet]

  *) Tweaked the headers_out table size, and the subprocess_env
     table size guess in rename_original_environment().  Added
     MAKE_TABLE_PROFILE which can help discover make_table()
     calls that use too small an initial guess, see alloc.c.
     [Dean Gaudet]

  *) Options and AllowOverride weren't properly merging in the main
     server setting inside vhosts (only an issue when you have no
     <Directory> or other section containing an Options that affects
     a request).  Options +foo or -foo in the main_server wouldn't
     affect the main_server's lookup defaults.  [Dean Gaudet]

  *) Variable 'cwd' was being used pointlessly before being set.
     [Ken Coar] PR#1738

  *) r->allowed handling cleaned up in the standard modules.
     [Dean Gaudet]

  *) Some case-sensitivity issues cleaned up to be consistent with
     RFC2068.  [Dean Gaudet]

  *) SIGURG doesn't exist everywhere.
     [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]

  *) mod_unique_id was erroneously generating a second unique id when
     an internal redirect occured.  Such redirects occur, for example,
     when processing a DirectoryIndex match.  [Dean Gaudet]

  *) API: table_add, table_merge, and table_set include implicit pstrdup()
     of the key and value.  But in many cases this is not required
     because the key/value is a constant, or the value has been built
     by pstrcat() or other similar means.  New routines table_addn,
     table_mergen, and table_setn have been added to the API, these
     routines do not pstrdup() their arguments.  The core code and
     standard modules were changed to take advantage of these routines.
     The resulting server is up to 20% faster in some situations.

     Note that it is easy to get code subtly wrong if you pass a key/value
     which is in a pool other than the pool of the table.  The only
     safe thing to do is to pass key/values which are in the pool of
     the table, or in one of the ancestors of the pool of the table.
     i.e. if the table is part of a subrequest, a value from the main
     request's pool is OK since the subrequest pool is a sub_pool of the
     main request's pool (and therefore has a lifespan at most as long as
     the main pool).  There is debugging code which can detect improper
     usage, enabled by defining POOL_DEBUG.  See alloc.c for more details.
     [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]

  *) More mod_mime_magic cleanup:  fewer syscalls; should handle "files"
     which don't exist on disk more gracefully; handles vhosts properly.
     Update documentation to reflect the code -- if there's no
     MimeMagicFile directive then the module is not enabled.
     [Dean Gaudet]

  *) PORT: Some older *nix dialects cannot automatically start scripts
     which begin with a #! interpreter line (the shell starts the scripts
     appropriately on these platforms). Apache now supports starting of
     "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
     [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
     taken from tcsh]

  *) API: "typedef array_header table" removed from alloc.h, folks should
     have been writing to use table as if it were an opaque type, but even
     some standard modules got this wrong.  By changing the definition
     to "typedef struct table table" module authors will receive compile
     time warnings that they're doing the wrong thing.  This change
     facilitates future changes with more sophisticated table
     structures.  Specifically, module authors should be using table_elts()
     to get access to an array_header * for the table. [Dean Gaudet]

  *) API: Renamed new_connection() to avoid namespace collision with LDAP
     library routines.  [Ken Coar, Rasmus Lerdorf]

  *) WIN32: mod_speling is now available on the Win32 platform.
     [Marc Slemko]

  *) For clarity the following compile time definition was changed:

        SAFE_UNSERIALIZED_ACCEPT  ->   SINGLE_LISTEN_UNSERIALIZED_ACCEPT

     Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
     and not be a general notice that the OS has mmap(). Now the
     HAVE_MMAP/SHMGET #defines strictly are informational that the
     OS has that method of shared memory; the type to use for
     the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
     and USE_SHMGET_SCOREBOARD). This allows outside modules to
     determine if shared memory is available and allows Apache
     to determine the best method to use for the scoreboard.
     [Jim Jagielski]

  *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
     as do various earlier versions.  It should be safe on all versions.
     Unixware 1.x appears to have the same SIGHUP bug as solaris does with
     the slack code.  A few other cleanups for Unixware.
     [Tom Hughes <thh@cyberscience.com>] PR#1082, PR#1282, PR#1499, PR#1553

  *) PORT: A/UX can handle single-listen accepts without mutex
     locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]

  *) When die() happens we need to eat any request body if one exists.
     Otherwise we can't continue with a keepalive session.  This shows up
     as a POST problem with MSIE 4.0, typically against pages which are
     authenticated.  [Roy Fielding] PR#1399

  *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
     header will be passed to CGIs.  This is generally a security hole, so
     it's not a default.  [Marc Slemko] PR#549

  *) Fix Y2K problem with date printing in suexec log.
     [Paul Eggert <eggert@twinsun.com>] PR#1343

  *) WIN32 deserves a pid file.  [Ben Hyde]

  *) suexec errors now include the errno/description.  [Marc Slemko] PR#1543

  *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
     The choice of flock vs. fcntl was made based on timings which showed that
     even on non-NFS, non-exported filesystems fcntl() was an order of
     magnitude slower.  It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
     that single socket users will see no difference. [Dean Gaudet] PR#467

  *) "File does not exist" error message was erroneously including the
     errno.  [Marc Slemko]

  *) Improve the warning message generated when a client drops the
     connection (hits stop button, etc.) during a send.  [Roy Fielding]

  *) Defining GPROF will disable profiling in the parent and enable it
     in the children.  If you're profiling under Linux this is pretty much
     necessary because SIGPROF is lost across a fork(). [Dean Gaudet]

  *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
     [Brian Havard]

  *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
     gcc functionality.  Work around it.
     [Keith Severson <keith@sssd.navy.mil>] PR#1613

  *) Some linkers complain when .o files contain no functions.
     [Keith Severson <keith@sssd.navy.mil>] PR#1614

  *) Some const declarations in mod_imap.c that were added for debugging
     purposes caused some compilers heartburn without adding any
     significant value, so they've been removed.  [Ken Coar]

  *) The src/main/*.h header files have had #ifndef wrappers added to
     insulate them against duplicate calls if they get included through
     multiple paths (e.g., in .c files as well as other .h files).
     [Ken Coar]

  *) The libap routines now have a header file for their prototypes,
     src/ap/ap.h, to ease their use in non-httpd applications.  [Ken Coar]

  *) mod_autoindex with a plaintext header file would emit the <PRE>
     start-tag before the HTML preamble, rather than after the preamble
     but before the header file contents.  [John Van Essen <jve@gamers.org>]
     PR#1667

  *) SECURITY: Fix a possible buffer overflow in logresolve.  This is
     only an issue on systems without a MAXDNAME define or where
     the resolver returns domain names longer than MAXDNAME.  [Marc Slemko]

  *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
     is used to read various types of files such as htaccess and
     htpasswd files.  [Marc Slemko]

  *) SECURITY: Ensure that the buffer returned by ht_time is always
     properly null terminated.  [Marc Slemko]

  *) The "Connection" header could be sent back with multiple "close"
     tokens.  Not an error, but a waste.
     [Ronald.Tschalaer@psi.ch] PR#1683

  *) mod_rewrite's RewriteLog should behave like mod_log_config, it
     shouldn't force hostname lookups.  [Dean Gaudet] PR#1684

  *) "basic" auth needs a case-insensitive comparison.
     [Ronald.Tschalaer@psi.ch] PR#1666

  *) For maximum portability, the environment passed to CGIs should
     only contain variables whose names match the regex
     /[a-zA-Z][a-zA-Z0-9_]*/.  This is now enforced by stamping
     underscores over any character outside the regex.  This
     affects HTTP_* variables, in a way that should be backward
     compatible for all the standard headers; and affects variables
     set with SetEnv/BrowserMatch and similar directives.
     [Dean Gaudet]

  *) mod_speling returned incorrect HREF's when an ambigous match
     was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
     [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]

  *) PORT: Apache now compiles & runs on an EBCDIC mainframe
     (the Siemens BS2000/OSD family) in the POSIX subsystem
     [Martin Kraemer]

  *) PORT: Fix problem killing children when terminating.  Allow ^C
     to shut down the server.  [Brian Havard]

  *) pstrdup() is implicit in calls to table_* functions, so there's
     no need to do it before calling.  Clean up a few cases.
     [Marc Slemko, Dean Gaudet]

  *) new -C and -c command line arguments
     usage:
     -C "directive" : process directive before reading config files
     -c "directive" : process directive after reading config files
     example:
     httpd -C "PerlModule Apache::httpd_conf"
     [Doug MacEachern, Martin Kraemer]

  *) WIN32: Fix the execution of CGIs that are scripts and called 
     with path info that does not have an '=' in.
     (eg. http://server/cgi-bin/printenv?foobar)  
     [Marc Slemko] PR#1591

  *) WIN32: Fix a call to os_canonical_filename so it doesn't try to 
     mess with fake filenames.  This fixes proxy caching on 
     win32. PR#1265

  *) SECURITY: General mod_include cleanup, including fixing several
     possible buffer overflows and a possible infinite loop.
     [Dean Gaudet, Marc Slemko]

  *) SECURITY: Numerous changes to mod_imap in a general cleanup
     including fixing a possible buffer overflow.  [Dean Gaudet]

  *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
     (connections are not dropped). Code can handle graceful restarts
     (but there is as yet no way to signal this to Apache). Various
     other cleanups. [Paul Sutton]

  *) The aplog_error changes specific to 1.3 introduced a buffer
     overrun in the (now legacy) log_printf function.  Fixed.
     [Dean Gaudet]

  *) mod_digest didn't properly deal with proxy authentication.  It
     also lacked a case-insensitive comparision of the "Digest"
     token.  [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599

  *) A few cleanups in mod_status for efficiency.  [Dean Gaudet]

  *) A few cleanups in mod_info to make it thread-safe, and remove an
     off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]

  *) no2slash() was O(n^2) in the length of the input.  Make it O(n).
     [Dean Gaudet]

  *) API: migration from strncpy() to our "enhanced" version called
     ap_cpystrn() for performance and functionality reasons.
     Located in libap.a.  [Jim Jagielski]

  *) table_set() and table_unset() did not deal correctly with
     multiple occurrences of the same key.
     [Stephen Scheck <sscheck@infonex.net>, Ben Laurie] PR#1604

  *) The AuthName must now be enclosed in quotes if it is to contain
     spaces.  [Ken Coar] PR#1195

  *) API: new function: ap_escape_quotes(). [Ken Coar] PR#1195

  *) WIN32: Work around optimiser bug that killed ISAPI in release
     versions. [Ben Laurie] PR#1533

  *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]

  *) Interim (slow) fix for p->sub_pool critical sections in
     alloc.c (affects win32 only).  [Ben Hyde]

  *) non-WIN32 was missing destroy_mutex definition.  [Ben Hyde]

  *) send_fd_length() did not calculate total_bytes_sent properly.
     [Ben Reser <breser@regnow.com>] PR#1366

  *) The bputc() macro was not properly integrated with the chunking
     code; in many cases modules using bputc() could cause completely
     bogus chunked output.  (Typically this will show up as problems
     with Internet Explorer 4.0 reading a page, but other browsers
     having no problem.) [Dean Gaudet]

  *) Create LARGE_WRITE_THRESHOLD define which determines how many
     bytes have to be supplied to bwrite() before it will consider
     doing a writev() to assemble multiple buffers in one system
     call.  This is critical for modules such as mod_include,
     mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
     strings in some cases.  The result would be extra effort
     setting up writev(), and in many cases extra effort building
     chunks.  The default is 31, it can be overriden at compile
     time. [Dean Gaudet]

  *) Move the gid switching code into the child so that log files
     and pid files are opened with the root gid.
     [Gregory A Lundberg <lundberg@vr.net>]

  *) WIN32: Check for binaries by looking for the executable header
     instead of counting control characters.
     [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340

  *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
     so the functionality is available to applications other than the
     server itself (like the src/support tools).  [Ken Coar]

  *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
     the libap consolidation work.  [Ken Coar]

  *) ap_snprintf() with a len of 0 behaved like sprintf().  This is not
     useful, and isn't what the standards require.  Now it returns 0
     and writes nothing.  [Dean Gaudet]

  *) When an error occurs in fcntl() locking suggest the user look up
     the docs for LockFile.  [Dean Gaudet]

  *) Eliminate some dead code from writev_it_all().
     [Igor Tatarinov <tatarino@prairie.NoDak.edu>]

  *) mod_autoindex had an fread() without checking the result code.
     It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"
     (note the missing closing paren) properly.  [Dean Gaudet]

  *) It appears the "257th byte" bug (see
     htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
     at the 256th byte as well.  Fixed.  [Dean Gaudet]

  *) PORT: Fix mod_mime_magic under OS/2, no support for block devices.
     [Brian Havard]

  *) Fix memory corruption caused by allocating auth usernames in the
     wrong pool.  [Dean Gaudet] PR#1500

  *) Fix an off-by-1, and an unterminated string error in
     mod_mime_magic.  [Dean Gaudet]

  *) Fix a potential SEGV problem in mod_negotiation when dealing
     with type-maps.  [Dean Gaudet]

  *) Better glibc support under Linux.  [Dean Gaudet] PR#1542

  *) "RedirectMatch gone /" would cause a SIGSEGV. [Dean Gaudet] PR#1319

  *) WIN32: avoid overflows during file canonicalisations.
     [malcolm@mgdev.demon.co.uk] PR#1378

  *) WIN32: set_file_slot() didn't detect absolute paths. [Ben Laurie]
     PR#1511, 1508

  *) WIN32: mod_status display header didn't match fields. [Ben Laurie]

  *) The pthread_mutex_* functions return an error code, and don't
     set errno.  [Igor Tatarinov <tatarino@prairie.NoDak.edu>]

  *) WIN32: Allow spaces to prefix the interpreter in #! lines.
     [Ben Laurie] PR#1101

  *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523

  *) proxy_ftp: the directory listings generated by the proxy ftp module
     now have a title in which the path components are clickable and allow
     quick navigation to the clicked-on directory on the currently listed
     ftp server. This also fixes a bug where the ".." directory links would
     sometimes refer to the wrong directory.  [Martin Kraemer]

     error messages. [Ben Hyde]

Changes with Apache 1.3b3

  *) WIN32: Work around brain-damaged spawn calls that can't deal
     with spaces and slashes.  [Ben Laurie]

  *) WIN32: Fix the code so CGIs can use socket calls on Windows.  
     The problem was that certain undocumented environment variables
     needed for sockets to work under Win32 were not being passed.
     [Frank Faubert <frank@sane.com>]

  *) Add a "-V" command line flag to the httpd binary.  This 
     flag shows some of the defines that Apache was compiled with.
     It is useful for debugging purposes.  [Martin Kraemer]

  *) Start separating the ap_*() routines into their own library, so they
     can be used by items in src/support among other things.  
     [Ken Coar] PR#512, 905, 1252, 1308 

  *) Give a more informative error when no AuthType is set.
     [Lars Eilebrecht]

  *) Remove strtoul() use from mod_proxy because it isn't available
     on all platforms.   [Marc Slemko] PR#1214

  *) WIN32: Some Win32 systems terminated all responses after 16 kB. 
     This turns out to be a bug in Winsock - select() doesn't always 
     return the correct status.  [Ben Laurie]

  *) Directives owned by http_core can now use the new check_cmd_context()
     routine to ensure that they're not being used within a container
     (e.g., <Directory>) where they're invalid.  [Martin Kraemer]

  *) PORT: Recent changes made it necessary to add explicit prototype
     for fgetc() and fgets() on SunOS 4.x.  [Martin Kraemer, Ben Hyde]

  *) It was necessary to distinguish between resources which are
     allocated in the parent, for cleanup in the parent, and resources
     which are allocated in each child, for cleanup in each child.
     A new pool was created which is passed to the module child_init
     and child_exit functions; modules are free to register per-child
     cleanups there.  This fixes a bug with reliable piped logs.
     [Dean Gaudet]

  *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
     unless it was also doing FancyIndexes, but it displayed the
     HeaderName file at the top under all circumstances.  It now shows
     the ReadmeName file for simple indices, too, as it should.  
     [Ken Coar] PR#1373

  *) http_core was mmap()ing even in cases where it wasn't going to
     read the file.  [Ben Hyde <bhyde@gensym.com>]

  *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
     Now the rewriting engine (the heart of mod_rewrite) is organized more
     straight-forward, first time well documented and reduced to the really
     essential parts. All redundant cases were stripped off and processing now
     is the same for both per-server and per-directory context with only a
     minimum difference (the prefix stripping in per-dir context). As a
     side-effect some subtle restrictions and two recently discovered problems
     are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
     context and restrictions on the substitution URL on redirects.
     Additionally some minor source cleanups were done.

  *) If ap_slack fails to allocate above the low slack line it's a good
     indication that further problems will occur; it's a better indication

  *) Preserve handler value on ProxyPass'ed requests by not
     calling find_types on a proxy'd request; fixes problems
     where some ProxyPass'ed URLs weren't actually passed
     to the proxy.
     [Lars Eilebrecht] PR#870

  *) Fix a byte ordering problem in mod_access which prevented
     the old-style syntax (i.e. "a.b.c." to match a class C)
     from working properly. [Dean Gaudet] PR#1248, 1328, 1384

  *) Fix problem with USE_FLOCK_SERIALIZED_ACCEPT not working
     properly. Each child needs to open the lockfile instead
     of using the passed file-descriptor from the parent. 
     [Jim Jagielski] PR#1056

  *) Fix the error logging in mod_cgi; the recent error log changes
     introduced a bug that prevented it from working correctly.
     [M.D.Parker] PR#1352

  *) Default to USE_FCNTL_SERIALIZED_ACCEPT on HPUX to properly 
     handle multiple Listen directives.  [Marc Slemko] PR#872

  *) Inherit a bugfix to fnmatch.c from FreeBSD sources.
     ["[KOI8-R] áÎÄÒÅÊ þÅÒÎÏ×" <ache@nagual.pp.ru>] PR#1311

  *) When a configuration parse complained about a bad directive,
     the logger would use whatever (unrelated) value was in errno.
     errno is now forced to EINVAL first in this case.  [Ken Coar]

  *) A sed command in the Configure script pushed the edge of POSIXness,
     breaking on some systems.  [Bhaba R.Misra <system@vt.edu>] PR#1368

  *) Solaris >= 2.5 was totally broken due to a mess up using pthread
     mutexes.  [Roy Fielding, Dean Gaudet]

  *) Warn user that default path has changed if /usr/local/etc/httpd
     is found on the system.  [Lars Eilebrecht]

  *) Various mod_mime_magic bug fixes and cleanups: Uncompression
     should work, it should work on WIN32, and a few resource
     leaks and abort conditions are fixed.
     [Dean Gaudet] PR#1205

  *) PORT: On AIX 1.x files can't be named '@', fix the proxy cache
     to use '%' instead of '@' in its encodings.
     [David Schuler <schuld@btv.ibm.com>] PR#1317

  *) Improve the warning message generated when the "server is busy".
     [Dean Gaudet] PR#1293

  *) PORT: All ports which don't otherwise define DEF_WANTHSREGEX will
     get Spencer regex by default.  This is to avoid having to
     discover bugs in operating system libraries.  [Dean Gaudet]

  *) PORT: "Fix" PR#467 by generating warnings on systems which we have
     not been able to get working USE_*_SERIALIZED_ACCEPT settings for.

  *) Various improvements in detecting config file errors (missing closing
     directives for <Directory>, <Files> etc. blocks, prohibiting global
     server settings in <VirtualHost> blocks, flagging unhandled multiple
     arguments to <Directory>, <Files> etc.)

     splits up a combined access log into separate files based on the
     name of the virtual host (listed first in the log records by "%v").
     [Ken Coar]

Changes with Apache 1.3b2 (there is no 1.3b1)

  *) TestCompile was not passing $LIBS [Dean Gaudet]

  *) Makefile.tmpl was not using $CFLAGS in the link phase. 
     [Martin Kraemer]

  *) Add debugging code to alloc.c.  Defining ALLOC_DEBUG provides a
     rudimentary memory debugger which can be used on live servers with
     low impact -- it sets all allocated and freed memory bytes to 0xa5.
     Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
     and free() for each object.  This is far more expensive and should
     only be used for testing with tools such as Electric Fence and
     Purify.  See main/alloc.c for more details.  [Dean Gaudet]

  *) Configure uses a sh trap and didn't set its exitcode properly.
     [Dean Gaudet] PR#1159

  *) Yet another vhost revamp.  Add the NameVirtualHost directive which
     explicitly lists the ip:port pairs that are to be used for name-vhosts.
     From a given ip:port, regardless what the Host: header is, you can
     only reach the vhosts defined on that ip:port.  The precedence of
     vhosts was reversed to match other precedences in the config --
     the earlier vhosts override the later vhosts.  All vhost matching was
     moved into http_vhost.[ch].  [Dean Gaudet]

  *) ap_inline can be used to force inlining.  GNUC __attribute__() can
     be used for whatever reason is appropriate (i.e. format() warnings
     for printf style functions).  Both are enabled only with
     gcc >= 2.7.x (so that we have fewer support issues with older
     versions).  [Dean Gaudet]

  *) Fix support for Proxy Authentication (we were testing the response
     status too early). [Marc Slemko]

  *) CoreDumpDirectory directive directs where the core file is
     written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
     received.  [Marc Slemko, Dean Gaudet]

  *) PORT: Support for Atari MINT.
     [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]

  *) When booting, apache will now detach itself from stdin, stdout,
     and stderr.  stderr will not be detached until after the config
     files have been read so you will be able to see initial error
     messages.  After that all errors are logged in the error_log.
     This makes it more convenient to start apache via rsh, ssh,
     or crontabs.  [Dean Gaudet] PR#523

  *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
     Also removed the auto-generated link to www.apache.org that was the
     source of so many misdirected bug reports.  [Roy Fielding, Marc Slemko]

  *) send_fb would not detect aborted connections in some situations.
     [Dean Gaudet]

  *) mod_include would use uninitialized data when parsing certain
     expressions involving && and ||. [Brian Slesinsky] PR#1139

  *) mod_imap should only handle GET methods.  [Jay Bloodworth]

  *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]

  *) mod_autoindex improperly counted &escapes; as more than one
     character in the description.  It also improperly truncated
     descriptions that were exactly the maximum length.
     [Martin Kraemer]

  *) RedirectMatch was not properly escaping the result (PR#1155).  Also
     "RedirectMatch /advertiser/(.*) $1" is now permitted.
     [Dean Gaudet]

  *) mod_include now uses symbolic names to check for request success
     and return HTTP errors, and correctly handles all types of
     redirections (previously it only did temporary redirect correctly).
     [Ken Coar, Roy Fielding]

  *) mod_userdir was modifying r->finfo in cases where it wasn't setting
     r->filename.  Since those two are meant to be in sync with each other
     this is a bug.  ["Paul B. Henson" <henson@intranet.csupomona.edu>]

  *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
     ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]

  *) Inetd mode (which is buggy) uses timeouts without having setup the
     jmpbuffer. [Dean Gaudet] PR#1064

  *) Work around problem under Linux where a child will start looping
     reporting a select error over and over.
     [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588

  *) Fixed error in proxy_util.c when looping through multiple host IP
     addresses. [Lars Eilebrecht] PR#974

  *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
     buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
     bytes before writing, but it will never split a log entry across a
     buffer boundary.  [Dean Gaudet]

  *) API: the short_score record has been split into two pieces, one which
     the parent writes on, and one which the child writes on.  As part of
     this change the get_scoreboard_info() function was removed, and
     scoreboard_image was exported.  This change fixes a race condition
     in file based scoreboard systems, and speeds up changes involving the
     scoreboard in earlier 1.3 development.  [Dean Gaudet]

  *) API: New register_other_child() API (see http_main.h) which allows
     modules to register children with the parent for maintenance.  It
     is disabled by defining NO_OTHER_CHILD.  [Dean Gaudet]

  *) API: New piped_log API (see http_log.h) which implements piped logs,
     and will use register_other_child to implement reliable piped logs
     when it is available.  The reliable piped logs part can be disabled
     by defining NO_RELIABLE_PIPED_LOGS.  At the moment reliable piped
     logs is only available on Unix. [Dean Gaudet]

  *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
     meets_conditions().  This allows conditional HTTP selection to be
     handled separately from the storing of the header fields, and provides
     the ability for CGIs to set their own ETags for conditional checking.
     [Ken Coar, Roy Fielding]  PR#895

  *) Changes to mod_log_config to allow naming of format strings.
     Format nicknames are defined with "LogFormat fmt nickname", and can
     be used with "LogFormat nickname" and "CustomLog logtarget nickname".
     [Ken Coar]

  *) New module, "mod_speling", which can help find files even when 
     the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]

  *) API: New function child_terminate() triggers the child process to
     exit, while allowing the child finish what it needs to for the
     current request first.  
     [Doug MacEachern, Alexei Kosut]

  *) Windows now defaults to using full status reports with mod_status.
     [Alexei Kosut] PR #1094

  *) *Really* disable all mod_rewrite operations if the engine is off.
     Some things (like RewriteMaps) were checked/performed even if they
     weren't supposed to be.  [Ken Coar] PR #991

  *) Implement a new timer scheme which eliminates the need to call alarm() all
     the time.  Instead a counter in the scoreboard for each child is used to
     show when the child has made forward progress.  The parent samples this
     counter every scoreboard maintenance cycle, and issues SIGALRM if no
     progress has been made in the timeout period.  This reduces the static
     request best-case syscall count to 22 from 29.  This scheme is only
     used by systems with memory-based scoreboards.  [Dean Gaudet]

  *) The proxy now properly handles CONNECT requests which are sent
     to proxy servers when using ProxyRemote.  [Marc Slemko] PR#1024

  *) A script called apachectl has been added to the support 
     directory.  This script allows you to do things such as 
     "apachectl start" and "apachectl restart" from the command
     line.  [Marc Slemko]

  *) Modules and core routines are now put into libraries, which
     simplifies the link line tremendously (among other advantages).
     [Paul Sutton]

  *) Some of the MD5 names defined in Apache have been renamed to have
     an `ap_' prefix to avoid conflicts with routines supplied by
     external libraries.  [Ken Coar]

  *) Removal of mod_auth_msql.c from the distribution. There are many
     other options for databases today. Rather than offer one option,
     offer none at this time. mod_auth_msql and other SQL database
     authentication modules can be found at the Apache Module Registry.
     http://modules.apache.org/ It would be nice to offer a generic
     mod_auth_sql option in the near future.

  *) PORT: BeOS support added [Alexei Kosut]

  *) Configure no longer accepts the -make option, since it creates
     Makefile on the fly based on Makefile.tmpl and Configuration.

  *) Apache now gracefully shuts down when it receives a SIGTERM, instead
     of forcibly killing off all its processes and exiting without
     cleaning up. [Alexei Kosut]

  *) API: A new field in the request_rec, r->mtime, has been added to
     avoid gratuitous parsing of date strings.  It is intended to hold
     the last-modified date of the resource (if applicable).  An
     update_mtime() routine has also been added to advance it if
     appropriate.  [Roy Fielding, Ken Coar]

  *) SECURITY: If a htaccess file can not be read due to bad permissions,
     deny access to the directory with a HTTP_FORBIDDEN.  The previous
     behavior was to ignore the htaccess file if it could not be read.
     This change may make some setups with unreadable htaccess files
     stop working.  [Marc Slemko] PR#817

  *) Add aplog_error() providing a mechanism to define levels of
     verbosity to the server error logging. This addition also provides
     the ability to log errors using syslogd. Error logging is configurable
     on a per-server basis using the LogLevel directive. Conversion
     of log_*() in progress. [Randy Terbush]

  *) Further enhance aplog_error() to not log filename, line number, and
     errno information when it isn't applicable. [Ken Coar, Dean Gaudet]

  *) WIN32: Canonicalise filenames under Win32. Short filenames are
     converted to long ones. Backslashes are converted to forward
     slashes. Case is converted to lower. Parts of URLs that do not
     correspond to files are left completely alone. [Ben Laurie]

  *) PORT: 2 new OSs added to the list of ports:
      Encore's UMAX V: Arieh Markel <amarkel@encore.com>
      Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>

  *) Add the server version (SERVER_VERSION macro) to the "server
     configured and running" entry in the error_log.  Also build an
     object file at link-time that contains the current time
     (SERVER_BUILT global const char[]), and include that in the
     message.  [Ken Coar]

  *) Set r->headers_out when sending responses from the proxy.
     This fixes things such as the logging of headers sent from
     the proxy.  [Marc Slemko] PR#659

  *) support/httpd_monitor is no longer distributed because the 
     scoreboard should not be file based if at all possible. Use
     mod_status to see current server snapshot.

  *) (set_file_slot): New function, allowing auth directives to be
     independent of the server root, so the server documents can be
     moved to a different directory or machine more easily.
     [David J. MacKenzie]

  *) If no TransferLog is given explicitly, decline
     to log.  This supports coexistence with other logging modules,
     such as the custom one that UUNET uses. [David J. MacKenzie]

  *) Check for titles in server-parsed HTML files.
     Ignore leading newlines and returns in titles.  The old behavior
     of replacing a newline after <title> with a space causes the
     title to be misaligned in the listing. [David J. MacKenzie]

  *) Change mod_cern_meta to be configurable on a per-directory basis.
     [David J. MacKenzie]

  *) Add 'Include' directive to allow inclusion of configuration
     files within configuration files. [Randy Terbush]

  *) Proxy errors on connect() are logged to the error_log (nothing
     new); now they include the IP address and port that failed
     (*that's* new).   [Ken Coar, Marc Slemko] PR#352

  *) Various architectures now define USE_MMAP_FILES which causes
     the server to use mmap() for static files.  There are two
     compile-time tunables MMAP_THRESHOLD (minimum number of bytes
     required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
     number of bytes written in one cycle from a single mmap()d object,
     default 32768).  [Dean Gaudet]

  *) API: Added post_read_request API phase which is run right after reading
     the request from a client, or right after an internal redirect.  It is
     useful for modules setting environment variables that depend only on
     the headers/contents of the request.  It does not run during subrequests
     because subrequests inherit pretty much everything from the main
     request. [Dean Gaudet]

  *) Added mod_unique_id which is used to generate a unique identifier for
     each hit, available in the environment variable UNIQUE_ID.
     [Dean Gaudet]

  *) init_modules is now called after the error logs have been opened.  This
     allows modules to emit information messages into the error logs.
     [Dean Gaudet]

  *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
     information for case where proxy module is not available. [Marc Slemko]

  *) PORT: Apache has need for mutexes to serialize its children around
     accept.  In prior versions either fcntl file locking or flock file
     locking were used.  The method is chosen by the definition of
     USE_xxx_SERIALIZED_ACCEPT in conf.h.  xxx is FCNTL for fcntl(),
     and FLOCK for flock().  New options have been added:
        - SYSVSEM to use System V style semaphores
        - PTHREAD to use POSIX threads (appears to work on Solaris only)
        - USLOCK to use IRIX uslock
     Based on timing various techniques, the following changes were made
     to the defaults:
        - Linux 2.x uses flock instead of fcntl
        - Solaris 2.x uses pthreads
        - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
          work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
     [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
     Martijn Koster <m.koster@pobox.com>]

  *) PORT: The semantics of accept/select make it very desirable to use
     mutexes to serialize accept when multiple Listens are in use.  But
     in the case where only a single socket is open it is sometimes
     redundant to serialize accept().  Not all unixes do a good job with
     potentially dozens of children blocked on accept() on the same
     socket.  It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
     the server will avoid serialization when listening on only one socket,
     and use serialization when listening on multiple sockets.
     [Dean Gaudet] PR#467

  *) Configure changes: TestLib replaced by TestCompile, which has
     some additional capability (such as doing a sanity check of
     the compiler and flags selected); the version of Solaris is now
     available via the #define value of SOLARIS2; IRIX n32bit libs
     now supported and selectable by new Configuration Rule: IRIXN32;
     We no longer default to -O2 optimization.  [Jim Jagielski]

  *) Updated Configure: Configuration now uses AddModule to specify
     module source or binary file location, relative to src directory.
     Modules can be dropped into modules/extra, or in their own 
     directory, and modules can come with a Makefile or Configure can 
     create one.  Modules can add compiler or library information to
