CHANGES

     up to it. [Robert Thau]

  *) Logs access failures due to symlink checks or invalid client address
     in the error log [Roy Fielding, Robert Thau]

  *) Symlink checks deal correctly with systems where lstat of
     "/path/to/some/link/" follows the link.  [Thau, Fielding]

  *) Doesn't reset DirectoryIndex to 'index.html' when
     other directory options are set in a .htaccess file.  [Robert Thau]

  *) Clarified init code and nuked bogus warning in mod_access.c
     [Florent Guillaume]

  *) Corrected several directives in sample srm.conf
     --- includes corrections to directory indexing icon-related directives
     (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
     icons for encodings right, and turning on AddEncoding by default).
     [Roy Fielding]

  *) Corrected descriptions of args to AddIcon and AddAlt in command table
     [James Cloos]

  *) INSTALL & README mention "contributed modules" directory [Brian
     Behlendorf]

  *) Fixed English in the license language...  "for for" --> "for".
     [Roy Fielding]

  *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
     mod_alias.c, merging it almost completely with handling of Alias, and
     adding a 'notes' field to the request_rec which allows the CGI module
     to discover whether the Alias module has put this request through
     ScriptAlias (which it needs to know for back-compatibility, as the old
     NCSA code did not check Options ExecCGI in ScriptAlias directories).
     [Robert Thau]

Changes with Apache 0.8.10                                       18 Aug 1995

  *) AllowOverride applies to the named directory, and not just
     subdirectories.  [David Robinson]

  *) Do locking for accept() exclusion (on systems that need it)
     using a special file created for the purpose in /usr/tmp, and
     not the error log; using the error log causes real problems
     if it's NFS-mounted; this is known to be the cause of a whole
     lot of "server hang" problems with Solaris.  [David Robinson;
     thanks to Merten Schumann for help diagnosing the problem].

Changes with Apache 0.8.9                                        12 Aug 1995

  *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]

  *) Nested includes see environment variables of the including document,
     for NCSA bug-compatibility (some sites have standard footer includes
     which try to print out the last-modified date).  [Eric Hagberg/Robert
     Thau]

  *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
     URI as a CGI script, even if it would have been treated as something
     else if requested directly, for NCSA back-compatibility.  (Note that
     this means that people who know the name of the script can see the
     code just by asking for it).  [Robert Thau]

  *) New version of dbmmanage script included in support directory as
     dbmmanage.new.

  *) Check if scoreboard file couldn't be opened, and say so, rather
     then going insane [David Robinson]

  *) POST to CGI works on A/UX [Jim Jagielski]

  *) AddIcon and AddAlt commands work properly [Rob Hartill]

  *) NCSA server push works properly --- the Arena bug compatibility
     workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
     if you still want the workaround).  [Rob Hartill]

  *) If client didn't submit any Accept-encodings, ignore encodings in
     content negotiation.  (NB this will all have to be reworked anyway
     for the new HTTP draft).  [Florent Guillaume]

  *) Don't dump core when trying to log timed-out requests [Jim Jagielski]

  *) Really honor CacheNegotiatedDocs [Florent Guillaume]

  *) Give Redirect priority over Alias, for NCSA bug compatibility
     [David Robinson]

  *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
     paralleling earlier bug fix for CGI [David Robinson]

  *) If DBM auth is improperly configured, report a server error and don't
     dump core.

  *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
     it seems to work well enough without it (even in a 10 hits/sec
     workout), and the overhead for the locking under A/UX is
     alarmingly high (though it is very low on other systems).
     [Eric Hagberg, Jim Jagielski]

  *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]

  *) Further de-Berklize mod_cookies.c; change the bogus #include.  [Brian
     Behlendorf/Eric Hagberg]

  *) More improvements to default Configuration for A/UX [Jim Jagielski]

  *) Compiles clean on NEXT [Rob Hartill]

  *) Compiles clean on SGI [Robert Thau]

Changes with Apache 0.8.8                                        08 Aug 1995

  *) SunOS library prototypes now never included unless explicitly
     requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
     people using GNU libc on SunOS are screwed by prototypes for the
     standard library.

     (Those who wish to compile clean with gcc -Wall on a standard
     SunOS setup need the prototypes, and may obtain them using
     -DSUNOS_LIB_PROTOTYPES.  Those wishing to use -Wall on a system
     with nonstandard libraries are presumably competent to make their
     own arrangements).

  *) Strips trailing '/' characters off both args to the Alias command,
     to make 'Alias /foo/ /bar/' work.

Changes with Apache 0.8.7                                        03 Aug 1995

  *) Don't hang when restarting with a child from 'TransferLog "|..."' running
     [reported by David Robinson]

  *) Compiles clean on OSF/1 [David Robinson]

  *) Added some of the more recent significant changes (AddLanguage stuff,
     experimental LogFormat support) to CHANGES file in distribution root
     directory

Changes with Apache 0.8.6                                        02 Aug 1995

  *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
     (If you actually wanted a conditional GET which bypassed the cache, you
     couldn't get it). [Reported by Roy Fielding]

  *) Properly terminate headers on '304 Not Modified' replies to conditional
     GETs --- no browser we can find cares much, but the CERN proxy chokes.
     [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]

  *) httpd -v doesn't call itself "Shambhala".  [Reported by Chuck Murcko]

  *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
     not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
     and older versions don't set the __SUNPRO_C preprocessor variable).  On
     all other systems, these are never used anyway.  [Reported by Mark Cox].

  *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.

Changes with Apache 0.8.5                                        01 Aug 1995

  *) Added last-minute configurable log experiment, as optional module

  *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
     properly.  (One-line fix to http_protocol.c).

  *) Work around bogus behavior when reloading from Netscape.
     It's Netscape's bug --- for some reason they expect a request with
     If-modified-since: to not function as a conditional GET if it also
     comes with Pragma: no-cache, which is way out of line with the HTTP
     spec (according to Roy Fielding, the redactor).

  *) Added parameter to set maximum number of server processes.

  *) Added patches to make it work on A/UX.  A/UX is *weird*.  [Eric Hagberg,
     Jim Jagielski]

  *) IdentityCheck bugfix [Chuck Murcko].

  *) Corrected cgi-src/Makefile entry for new imagemap script.  [Alexei Kosut]

  *) More sample config file corrections; add extension to AddType for
     *.asis, move AddType generic description to its proper place, and
     fix miscellaneous typos. [ Alexei Kosut ]

  *) Deleted the *other* reference to the regents from the Berkeley
     legal disclaimer (everyplace).

  *) Nuked Shambhala name from src/README; had already cleaned it out
     of everywhere else.

Changes with Apache 0.8.4

  *) Changes to server-pool management parms --- renamed current
     StartServers to MinSpareServers, created separate StartServers
     parameter which means what it says, and renamed MaxServers to
     MaxSpareServers (though the old name still works, for NCSA 1.4
     back-compatibility).  The old names were generally regarded as
     too confusing.  Also altered "docs" in sample config files.

  *) More improvements to default config files ---
     sample directives (commented out) for XBitHack, BindAddress,
     CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
     defaults, AddTypes for send-as-is and imagemap magic types, and
     improvements to samples for DirectoryIndex [Alexei Kosut]

  *) Yet more improvements to default config files --- changes to
     Alexei's sample AddLanguage directives, and sample LanguagePriority
     [ Florent Guillaume ]

  *) Set config file locations properly if not set in httpd.conf
     [ David Robinson ]

  *) Don't escape URIs in internal redirects multiple times; don't
     do that when translating PATH_INFO to PATH_TRANSLATED either.
     [ David Robinson ]

  *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]

Changes with Apache 0.8.3

  *) Edited distribution README to *briefly* summarize installation
     procedures, and give a pointer to the INSTALL file in the src/
     directory.

  *) Upgraded imagemap script in cgi-bin to 1.8 version from more
     recent NCSA distributions.

  *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
     exist for the same directory, use both and don't segfault.  [Reported
     by David Robinson]

  *) Proper makefile dependencies [David Robinson]

  *) Note (re)starts in error log --- reported by Rob Hartill.

  *) Only call no2slash() after get_path_info() has been done, to
     preserve multiple slashes in the PATH_INFO [NCSA compatibility,
     reported by Andrew Wilson, though this one is probably a real bug]

  *) Fixed mod_imap.c --- relative paths with base_uri referer don't
     dump core when Referer is not supplied. [Randy Terbush]

  *) Lightly edited sample config files to refer people to our documentation
     instead of NCSA's, and to list Rob McCool as *original* author (also
     deleted his old, and no doubt non-functional email address).  Would be
     nice to have examples of new features...

Changes with Apache 0.8.2                                        19 Jul 1995

  *) Added AddLanuage code [Florent Guillaume]

  *) Don't say "access forbidden" when a CGI script is not found.  [Mark Cox]

  *) All sorts of problems when MultiViews finds a directory.  It would
     be nice if mod_dir.c was robust enough to handle that, but for now,
     just punt.  [reported by Brian Behlendorf]

  *) Wait for all children on restart, to make sure that the old socket
     is gone and we can reopen it.  [reported by Randy Terbush]

  *) Imagemap module is enabled in default Configuration

  *) RefererLog and UserAgentLog modules properly default the logfile
     [Randy Terbush]

  *) Mark Cox's mod_cookies added to the distribution as an optional
     module (commented out in the default Configuration, and noted as
     an experiment, along with mod_dld). [Mark Cox]

  *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]

  *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]

  *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]

  *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
     license]

Changes with Apache 0.8.1

  *) New imagemap module [Randy Terbush]

  *) Replacement referer log module with NCSA-compatible RefererIgnore
     [Matthew Gray again]

  *) Don't mung directory listings with very long filenames.
     [Florent Guillaume]

Changes with Apache 0.8.0 (nee Shambhala 0.6.2)                  16 Jul 1995

  *) New config script.  See INSTALL for info.  [Robert Thau]

  *) Scoreboard mechanism for regulating the number of extant server
     processes.  MaxServers and StartServers defaults are the same as
     for NCSA, but the meanings are slightly different.  (Actually,
     I should probably lower the MaxServers default to 10).

     Before asking for a new connection, each server process checks
     the number of other servers which are also waiting for a
     connection.  If there are more than MaxServers, it quietly dies
     off.  Conversely, every second, the root, or caretaker, process
     looks to see how many servers are waiting for a new connection;
     if there are fewer than StartServers, it starts a new one.  This
     does not depend on the number of server processes already extant.
     The accounting is arranged through a "scoreboard" file, named
     /tmp/htstatus.*, on which each process has an independent file
     descriptor (they need to seek without interference).

     The end effect is that MaxServers is the maximum number of
     servers on an *inactive* server machine, but more will be forked
     off to handle unusually heavy loads (or unusually slow clients);
     these will die off when they are no longer needed --- without
     reverting to the overhead of full forking operation.  There is a
     hard maximum of 150 server processes compiled in, largely to
     avoid forking out of control and dragging the machine down.
     (This is arguably too high).

     In my server endurance tests, this mechanism did not appear to
     impose any significant overhead, even after I forced it to put the
     scoreboard file on a normal filesystem (which might have more
     overhead than tmpfs).  [Robert Thau]

  *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
     [Cliff Skolnick]

  *) Read .htaccess files even in directory with <Directory> section.
     (Former incompatibility noted on mailing list, now fixed). [Robert
     Thau]

  *) "HEAD /" gives the client a "Bad Request" error message, rather
     than trying to send no body *and* no headers.  [Cliff Skolnick].

  *) Don't produce double error reports for some very obscure cases
     mainly involving auth configuration (the "all modules decline to
     handle" case which is a sure sign of a server bug in most cases,
     but also happens when authentication is badly misconfigured).
     [Robert Thau]

  *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
     it's *for*, and this sort of thing really shouldn't be cluttering
     up the Makefile). [Robert Thau]

  *) Incidental code cleanups in http_main.c --- stop dragging
     sa_client around; just declare it where used.  [Robert Thau]

  *) Another acc-related fix.  (It doesn't like const char
     in some places...). [Mark Cox]

Changes with Shambhala 0.6.1                                     13 Jul 1995

  *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
     Also, fixed auth typo in http_protocol.c unmasked by this fix.

  *) Compiles clean with acc on SunOS [Paul Sutton]

  *) Reordered modules in modules.c so that Redirect takes priority
     over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
     believe it or not, he has an actual site with a ScriptAlias and
     a Redirect declared for the *exact same directory*.  Even *my*
     compatibility fetish wouldn't motivate me to fix this if the fix
     required any effort, but it doesn't, so what the hey.

  *) Fixed to properly default several server_rec fields for virtual
     servers from the corresponding fields in the main server_rec.
     [Cliff Skolnick --- 'port' was a particular irritant].

  *) No longer kills off nph- child processes before they are
     finished sending output. [Matthew Gray]

Changes with Shambhala 0.6.0                                     10 Jul 1995

  *) Two styles of timeout --- hard and soft.  soft_timeout()s just put
     the connection to the client in an "aborted" state, but otherwise
     allow whatever handlers are running to clean up.  hard_timeout()s
     abort the request in progress completely; anything not tied to some
     resource pool cleanup will leak.  They're still around because I
     haven't yet come up with a more elegant way of handling
     timeouts when talking to something that isn't the client.  The
     default_handler and the dir_handler now use soft timeouts, largely
     so I can test the feature.  [Robert Thau]

  *) TransferLog "| my_postprocessor ..." seems to be there.  Note that
     the case of log handlers dying prematurely is probably handled VERY
     gracelessly at this point, and if the logger stops reading input,
     the server will hang.  (It is known to correctly restart the
     logging process on server restart; this is (should be!) going through
     the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
     script).  [Robert Thau]

  *) asis files supported (new module).  [Robert Thau]

  *) IdentityCheck code is compiled in, but has not been tested.  (I
     don't know anyone who runs identd). [Robert Thau]

  *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
     came in with the request, for NCSA bug-compatibility. [Robert Thau]

  *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]

  *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
     as timeouts are not in scope. [Robert Thau]

  *) quoted-string args in config files now handled correctly (doesn't drop
     the last character). [Robert Thau; reported by Randy Terbush]

  *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
     How the hell did it ever work? [Robert Thau; reported by Rob Hartill]

  *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
     default default type); the former default default behavior when all
     type-checkers defaulted had been a core dump.  [Paul Sutton]

  *) Copy filenames out of the struct dirent when indexing
     directories.  (On Linux, readdir() returns a pointer to the same
     memory area every time).  Fix is in mod_dir.c.  [Paul Sutton]

Changes with Shambhala 0.5.3 [not released]

  *) Default response handler notes "file not found" in the error log,
     if the file was not found.  [Cliff Skolnick].

  *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
     code no longer sets up bogus PATH_INFO which fakes out the directory
     handler). [Cliff Skolnick]

Changes with Shambhala 0.5.2                                     06 Jul 1995

  *) Changes to http_main.c --- root server no longer plays silly
     games with SIGCHLD, and so now detects and replaces dying
     children.  Child processes just die on SIGTERM, without taking
     the whole process group with them.  Potential problem --- if any
     child process refuses to die, we hang in restart.
     MaxRequestsPerChild may still not work, but it certainly works
     better than it did before this!  [Robert Thau]

  *) mod_dir.c bug fixes: ReadmeName and HeaderName
     work (or work better, at least); over-long description lines
     properly terminated. [Mark Cox]

  *) http_request.c now calls unescape_url() more places where it
     should [Paul Sutton].

  *) More directory handling bugs (reported by Cox)
     Parent Directory link is now set correctly. [Robert Thau]

Changes with Shambhala 0.5.1                                     04 Jul 1995

  *) Generalized cleanup interface in alloc.c --- any function can be
     registered with alloc.c as a cleanup for a resource pool;
     tracking of files and file descriptors has been reimplemented in
     terms of this interface, so I can give it some sort of a test.
     [Robert Thau]

  *) More changes in alloc.c --- new cleanup_for_exec() function,
     which tracks down and closes all file descriptors which have been
     registered with the alloc.c machinery before the server exec()s a
     child process for CGI or <!--#exec-->.  CGI children now get
     started with exactly three file descriptors open.  Hopefully,
     this cures the problem Rob H. was having with overly persistent
     CGI connections. [Robert Thau]

  *) Mutual exclusion around the accept() in child_main() --- this is
     required on at least SGI, Solaris and Linux, and is #ifdef'ed in
     by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
     This uses fcntl(F_SETLK,...) on the error log descriptor because
     flock() on that descriptor won't work on systems which have BSD
     flock() semantics, including (I think) Linux 1.3 and Solaris.

     This does work on SunOS (when the server is idle, only one
     process in the pool is waiting on accept()); it *ought* to work
     on the other systems. [Robert Thau]

  *) FreeBSD and BSDI portability tweaks [Chuck Murcko]

  *) sizeof(*sa_client) bugfix from [Rob Hartill]

  *) pstrdup(..., NULL) returns NULL, [Randy Terbush]

  *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
     be unnecessary if I go to the revised timeout-handling scheme).
     [Robert Thau]

  *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
     string) even if none came in with the request.  [Robert Thau]

  *) CHANGES file added to distribution ;-).

Changes with Shambhala 0.4.5

  *) mod_dld --- early dynamic loading support [rst]
  *) Add wildcard content handlers for XBITHACK; default_hander now
     invoked with that mechanism (as a handler hanging off mod_core) [rst]
  *) XBITHACK supported as a wildcard content-handler, and 
     configurable at run-time (not just at compile time, as in the
     "patchy server" releases) [rst]

Changes with Shambhala 0.4.4                                     30 Jun 1995

  *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
  *) Handle Addtype x/y .z [rst, reported by Cox]

Changes with Shambhala 0.4.3

  *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
     synonymous [rst, terbush]

Changes with Shambhala 0.4.1                                     28 Jun 1995

  *) First-cut virtual host implementation; some refit in the config
     reading code, and log management, was necessary to support this [rst]
  *) Sub-pool machinery, originally added to avoid excessive storage
     allocation on listings of large directories (which turned out to
     be the problem that the 0.3 storage accounting was added to
     find).  Subrequests and mod_dir changed to use subpools.  [rst]
  *) More memory debugging --- free list consistency checks. [rst]
  *) Added err_headers to request_rec, with support elsewhere [rst]
  *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]

Changes with Shambhala 0.3                                       19 Jun 1995

  *) Switch ONE_PROCESS to a runtime command-line option (-X)
  *) Don't compile in mod_ai_backcompat by default
  *) Switch name of server from Apache to Shambhala in Makefile
  *) Add some accounting routines to track memory usage in the pools,
     for debugging

Changes with Shambhala 0.2

  *) Set DOCUMENT_ROOT CGI variable
  *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
  *) Add critical section protection to handling of cleanup structures 
     in alloc.c [rst]
  *) Significant code reorg within the server core to group related
     functions together [rst]
  *) Correctly handle clients that hang up before sending any request
     [rst]
  *) Replace dying child processes. [rst]

Changes with Shambhala 0.1                                       12 Jun 1995

   Major rewrite of the pre-existing "patchy server" codebase, by
   Robert Thau (rst).  Significant portions of the server code, such
   as configuration-file handling and HTTP authentication support,
   were ripped out and rewritten from scratch.  Code that was not
   completely rewritten was significantly altered.

   Major changes with this release include:

   *) Introduction of the module API; in request handling, the central 
      machinery just dispatches to various modules, which actually do
      most of the work.  Configuration handling is similar --- modules
      declare their own commands, and the central machinery just
      dispatches to them.  

      API features from shambhala/0.1 were substantially unchanged in
      Apache 1.0 and 1.1.  (1.0 API features not yet present in this
      release, such as wildcard handlers and subpools, were added in
      subsequent Shambhala releases, and were also generally rst's
      work). 

   *) This release included the following modules:

      mod_access      (access control --- allow and deny directives),
      mod_alias       (Alias and Redirect commands),
      mod_auth        (straight HTTP authentication, based on flat-files)
      mod_auth_dbm    (same, with dbm files)
      mod_cgi         (CGI scripts and, in this release, ScriptAlias)
      mod_common_log  (CLF access logs; later renamed mod_log_common)
      mod_dir         (directory indexing)
      mod_include     (server-side includes)
      mod_mime        (AddType directives)
      mod_negotiation (content negotiation)
      mod_userdir     (support for users' public_html directories)

      It also included a mod_ai_backcompat, which was a private hack
      for back-compatibility with rst's own AI-lab servers.

      All of these modules were substantially complete, and functional 
      or nearly so (a few, which implemented features not in use at
      Thau's site, required patches of a few lines).

   *) sub-request machinery, to allow modules to determine how other
      modules would assign MIME types to a given file, or optionally
      serve its content (this is heavily used by mod_dir, mod_include
      and mod_negotiation).

   *) Resource pool system for keeping track of memory allocated and
      files opened in service of a particular request.  Much of the
      code in the modules (when they weren't rewrites) was adjusted to 
      replace a pervasive convention of using fixed-size buffers on
      the stack with an equally pervasive convention of using memory
      allocated with palloc().

   *) Reorganization of data structures associated with a given
      request to eliminate use of global variables and the troublesome 
      unmunge_name function (used in NCSA and early Apache releases to 
      attempt to determine the URI which mapped to a given filename
      --- a difficult proposition, given that it is easy to produce
      setups in which multiple URIs map to the same file).

   *) Source files renamed and rearranged

   *) Very simple pre-forking behavior --- parent process forked off a 
      fixed number of children, and then just waited for SIGHUP.

   *) Other more minor changes too numerous to list.

   This release included modified versions of a lot of code from the
   Apache 0.6.4 public release, plus an early pre-forking patch
   codeveloped by Robert Thau and Rob Hartill.

Changes with Apache 0.7.3                                        20 Jun 1995

   *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
      were incorporated by Rob Hartill on the main branch while Robert Thau
      worked on the Shambhala rewrite above.  Most were merged into the
      Shambala architecture after Apache 0.8.0.
