- Changes with Apache 1.0.5
-
- *) util.c in src fixed to escape newlines on shell commands
- [Ben Laurie]
-
- Changes with Apache 1.0.4
-
- *) util.c in cgi-src fixed to escape newlines on shell commands
- [Ben Laurie]
-
- Changes with Apache 1.0.3
-
- *) Internal redirects which occur in mod_dir.c now preserve the
- query portion of a request (the bit after the question mark).
- [Adam Sussman]
-
- *) Escape active characters '<', '>' and '&' in html output in
- directory listings, error messages and redirection links.
- [David Robinson]
-
- *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
-
- *) Fix for POSIX compliance in waiting for processes in alloc.c
- [Nick Williams]
-
- *) setsockopt no longer takes a const declared argument [Martijn Koster]
-
- *) Reset timeout timer after each successful fwrite() to the network.
- This patch adds a reset_timeout() procedure that is called by
- send_fd() to reset the timeout ever time data is written to the net.
- [Nathan Schrenk]
-
- *) timeout() signal handler now checks for SIGPIPE and reports
- lost connections in a more user friendly way. [Rob Hartill]
-
- *) Location of the file ( default logs/apache_runtime_status ) can be
- altered by httpd.conf ScoreBoardFile setting - works similar
- to PidFile (lots of PidFile stuff copied)
-
- *) Include sys/resource.h in the correct place for SunOS4 [Samerr Parekh]
-
- *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
- which caused a SEGV with cookies enabled
-
- *) Output warning when MinSpareServers is set to <= 0 and change it to 1
- [Rob Hartill]
-
- *) Log the UNIX textual error returned by some system calls, in
- particular errors from accept() [David Robinson]
-
- *) Add strerror function to util.c for SunOS4 [Randy Terbush]
-
- Changes with Apache 1.0.2
-
- *) patch to get Apache compiled on UnixWare 2.x, recommended as
- a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
-
- *) Fix get_basic_auth_pw() to set the auth_type of the request.
- [David Robinson]
-
- *) past changes to http_config.c to only use the
- setrlimit function on systems defining RLIMIT_NOFILE
- broke the feature on SUNOS4. Now defines HAVE_RESOURCE
- for SUNOS and prototypes the needed functions.
-
- *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
- [David Robinson]
-
- *) Fix use of pointer to scratch memory. [Cliff Skolnick]
-
- *) Merge multiple headers from CGI scripts instead of taking last
- one. [David Robinson]
-
- *) Add support for SCO 5. [Ben Laurie]
-
- Changes with Apache 1.0.1
-
- *) Silence mod_log_referer and mod_log_agent if not configured
- [Randy Terbush]
-
- *) Recursive includes can occur if the client supplies PATH_INFO data
- and the server provider uses relative links; as file.html
- relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
-
- *) The replacement for initgroups() did not call {set,end}grent(). This
- had two implications: if anything else used getgrent(), then
- initgroups() would fail, and it was consuming a file descriptor.
- [Ben Laurie]
-
- *) On heavily loaded servers it was possible for the scoreboard to get
- out of sync with reality, as a result of a race condition.
- The observed symptoms are far more Apaches running than should
- be, and heavy system loads, generally followed by catastrophic
- system failure. [Ben Laurie]
-
- *) Fix typo in licence. [David Robinson]
-
- Changes with Apache 1.0.0
-
- *) 'dbmmanage' script now takes fourth command-line argument, which is
- group(s) of the user, if given. [Rob Hartill]
-
- *) httpd_monitor Perl utility script added to "support" directory;
- lets you know what your active server processes are up to. [Known
- to work on SunOS and HP-UX at least]. [Rob Hartill]
-
- *) Passes TZ environment variable to child processes if set on startup
- [ David Robinson ]
-
- *) Attempting to retrieve the URI /foo/bar/zot.map (an imagemap request
- with *no* QUERY_STRING) returns the default URL, rather than a core
- dump. [Mark Cox]
-
- *) Attempting to configure auth without any "requires" lines should now
- be equivalent to "require valid-user", rather than a core dump.
- [Patch supplied by J. Katzman]
-
- *) Getparents() routine fixed to handle some awkward corner cases better;
- in particular, '/./' is eliminated from incoming URIs. Also fixed the
- no2slash() utility routine to reduce any number of consecutive slashes
- to one. These changes keep "trick" URIs from avoiding <Directory>
- checks. [David Robinson]
-
- *) Allowed any number of '/' characters to match a single '/' when
- checking for Aliases; this keeps certain ScriptAlias directives
- from getting bypassed. [Robert Thau]
-
- *) DBM group code now checks all groups, not just the first [Rob Hartill]
-
- *) "allow from good.com" no longer allows clients from nogood.com to
- connect; formerly this was allowed because the terminal substrings
- do match. [Robert Thau]
-
- *) Transactions interrupted in the middle of processing some include
- directive are now logged correctly [Robert Thau]
-
- *) Cleaned up Configure script so it doesn't abuse EXTRA_LIBS to specify
- host-specific default libraries. [Ben Laurie]
-
- *) Cleaned up http_main code a bit; IdentityCheck may now work better on
- systems with virtual hosts. [David Robinson]
-
- *) Improved installation instructions in top-level README [Brian Behlendorf]
-
- Changes with Apache 0.8.16
-
- *) New man page for 'httpd' added to support directory [David Robinson]
-
- *) .htgroup files can have more than one line giving members for a
- given group (each must have the group name in front), for NCSA
- back-compatibility [Robert Thau]
-
- *) Mutual exclusion around accept() is on by default for SVR4 systems
- generally, since they generally can't handle multiple processes in
- accept() on the same socket. This should cure flaky behavior on
- a lot of those systems. [David Robinson]
-
- *) AddType, AddEncoding, and AddLanguage directives take multiple
- extensions on a single command line [David Robinson]
-
- *) UserDir can be disabled for a given virtual host by saying
- "UserDir disabled" in the <VirtualHost> section --- it was a bug
- that this didn't work. [David Robinson]
-
- *) Compiles on QNX [Ben Laurie]
-
- *) Corrected parsing of ctime time format [David Robinson]
-
- *) httpd does a perror() before exiting if it can't log its pid
- to the PidFile, to make diagnosing the error a bit easier.
- [David Robinson]
-
- *) <!--#include file="..."--> can no longer include files in the
- parent directory, for NCSA back-compatibility. [David Robinson]
-
- *) '~' is *not* escaped in URIs generated for directory listings
- [Roy Fielding]
-
- *) Eliminated compiler warning in the imagemap module [Randy Terbush]
-
- *) Fixed bug involving handling URIs with escaped %-characters
- in redirects [David Robinson]
-
- Changes with Apache 0.8.15
-
- *) Switched to new, simpler license
-
- *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
-
- *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
-
- *) Reject paths containing %-escaped '%' or null characters [David Robinson]
-
- *) Correctly handles internal redirects to files with names containing '%'
- [David Robinson]
-
- *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
-
- *) Use geteuid() rather than getuid() to see if we have root privilege,
- so that server correctly resets privilege if run setuid root. [Andrew
- Wilson]
-
- *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
- [Randy Terbush]
-
- *) Fix relative URLs in imagemap files [Randy Terbush]
-
- *) Somewhat better fix for the old "Alias /foo/ /bar/" business
- [David Robinson]
-
- *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
- entries all name the same one. [David Robinson]
-
- *) Fix directory listings with filenames containing unusual characters
- [David Robinson]
-
- *) Better URI-escaping for generated URIs in directories with filenames
- containing unusual characters [Ben Laurie]
-
- *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
-
- *) Unblock alarms on error return from spawn_child() [David Robinson]
-
- *) Sample Config files have extra note for SCO users [Ben Laurie]
-
- *) Configuration has note for HP-UX users [Rob Hartill]
-
- *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
-
- *) Nuked bogus #define in httpd.h [David Robinson]
-
- *) Better test for whether a system has setrlimit() [David Robinson]
-
- *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
-
- *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
- [Ben Laurie]
-
- Changes with Apache 0.8.14
-
- *) Compiles on SCO ODT 3.0 [Ben Laurie]
-
- *) AddDescription works (better) [Ben Laurie]
-
- *) Leaves an intelligible error diagnostic when it can't set group
- privileges on standalone startup [Andrew Wilson]
-
- *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
- that machine, which claims to be BSD but does not support RLIMIT.
- [Randy Terbush]
-
- *) gcc -Wall no longer complains about an unused variable when util.c
- is compiled with -DMINIMAL_DNS [Andrew Wilson]
-
- *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
-
- Changes with Apache 0.8.13
-
- *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
-
- *) Have built-in imagemap code recognize & honor Point directive [James
- Cloos]
-
- *) Generate cleaner directory listings in directories with a mix of
- long and short filenames [Rob Hartill]
-
- *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
-
- *) Properly default ServerName for virtual servers [Robert Thau]
-
- *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
- Paul Richards and a cast of thousands...]
-
- *) On self-identified BSD systems (we don't try to guess any more),
- allocate a few extra file descriptors per virtual host with setrlimit,
- if we can, to avoid running out. [Randy Terbush]
-
- *) Write 22-character lock file name into buffer with enough space
- on startup [Konstantin Olchanski]
-
- *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
- Pinkerton]
-
- *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
-
- *) Suppress -Wall warning by initializing variable in negotation code
- [Tobias Weingartner]
-
- Changes with Apache 0.8.12
-
- *) Doesn't pause three seconds after including a CGI script which is
- too slow to die off (this is done by not even trying to kill off
- subprocesses, including the SIGTERM/pause/SIGKILL routine, until
- after the entire document has been processed). [Robert Thau]
-
- *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
-
- *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
-
- *) Allows .htaccess files to override <Directory> sections naming the
- same directory [David Robinson]
-
- *) Removed an efficiency hack in sub_req_lookup_uri which was
- causing certain extremely marginal cases (e.g., ScriptAlias of a
- *particular* index.html file) to fail. [David Robinson]
-
- *) Doesn't log an error when the requested URI requires
- authentication, but no auth header line was supplied by the
- client; this is a normal condition (the client doesn't no auth is
- needed here yet). [Robert Thau]
-
- *) Behaves more sanely when the name server loses its mind [Sean Welch]
-
- *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
-
- *) RFC931 code no longer passes out name of prior clients on current
- requests if the current request came from a server that doesn't
- do RFC931. [David Robinson]
-
- *) Configuration script accepts "Module" lines with trailing whitespace.
- [Robert Thau]
-
- *) Cleaned up compiler warning from mod_access.c [Robert Thau]
-
- *) Cleaned up comments in mod_cgi.c [Robert Thau]
-
- Changes with Apache 0.8.11
-
- *) Wildcard <Directory> specifications work. [Robert Thau]
-
- *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
-
- *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
- the file being requested itself, in addition to the directories leading
- 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]
-
- *) Clarifed 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-combatibility, as the old
- NCSA code did not check Options ExecCGI in ScriptAliased directories).
- [Robert Thau]
-
-
- Changes with Apache 0.8.10
-
- *) 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
-
- *) 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-combatibility. (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 Jaglieski]
-
- *) 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 Jaglieski]
-
- *) 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]
-
- *) 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 Jaglieski]
-
- *) Compiles clean on NEXT [Rob Hartill]
-
- *) Compiles clean on SGI [Robert Thau]
-
- Changes with Apache 0.8.8
-
- *) 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
-
- *) 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
-
- *) 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
-
- *) 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]
-
- *) 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-combatibility). 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
-
- *) 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):
-
- *) 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 independant 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 0.6.1
-
- *) 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 0.6.0
-
- *) 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 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 0.5.2
-
- *) 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 0.5.1: [Hopefully complete]
-
- *) 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 ;-).
