7 Changes with Apache 2.0.37
9 *) allow POST method over SSL when per-directory client cert
10 authentication is used with 'SSLOptions +OptRenegotiate' enabled
11 and a client cert was found in the ssl session cache.
13 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
14 session cache when there is no cert chain in the cache. prior to
15 the fix this situation would result in a FORBIDDEN response and
16 error message "Cannot find peer certificate chain"

26 change to the Apache directory (one level above the location
27 of Apache.exe, in the case that Apache.exe resides in bin/.)
28 Solves the case of ServerRoot /foo paths where /foo was not
29 on the same drive as /winnt/system32. [William Rowe]
31 *) Make 2.0's "AcceptMutex" startup message now "completely"
32 match how 1.3 does it. [Jim Jagielski]
34 *) Implement a fixed size memory cache using a priority queue
37 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
38 querying certain other variables from config_vars.mk. PR 9316
41 *) Added the "detached" attribute to the cgi_exec_info_t internals
42 so that Win32 and Netware won't create a new window or console
43 for each CGI invoked. PR 8387
44 [Brad Nicholes, William Rowe]
46 *) Consolidated the command line parameters and attributes that are
47 manipulated by the optional function ap_cgi_build_command() in
48 mod_cgi into a single structure.
51 *) Get rid of uninitialized value errors with "apxs -q" on certain
52 variables. [Stas Bekman <stas@stason.org>]
54 *) Fix apxs to allow it to work when the build directory is somewhere
55 besides server-root/build. PR 8453
56 [Jeff Trawick and a host of others]
58 *) Allow ap_discard_request_body to be called multiple times in the
59 same request. Essentially, ap_http_filter keeps track of whether
60 it has sent an EOS bucket up the stack, if so, it will only ever
61 send an EOS bucket for this request.

64 *) Remove all special mod_ssl URIs. This also fixes the bug where
65 redirecting (.*) will allow an SSL protected page to be viewed
66 without SSL. [Ryan Bloom]
68 *) Fix the binary build install script so that the build logic
69 created by "apxs -g" will work when the user has a binary
72 *) Allow instdso.sh to work with full paths to the shared module.
75 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
76 in module for NetWare [Brad Nicholes]
78 *) Changed cgi and piped log behavior to accept 65536 characters
79 on Win32 (matching Linux) before deadlocking between outputing
80 client stdin, slurping the output from stdout and then the stderr
81 stream. PR 8179 [William Rowe]
83 *) Fixed Win32 wintty.exe support to assure the window title is valid.
84 Elimiates possible gpfault or garbage title without the -t option.

113 it should to avoid conditions in some modules that could cause
114 large amounts of data to be buffered. [Cliff Woolley]
116 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
117 stripping the content_type from cached responses.
120 *) apachectl passes through any httpd options. Note: apachectl
121 should be used in preference to httpd since it ensures that any
122 appropriate environment variables have been set up.

168 It is currently ignored and it will be removed in a future release
169 of Apache. [Jeff Trawick]

177 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
179 *) OS/390: LIBPATH no longer has to be manually uncommented in
180 envvars to get apachectl to set up httpd properly. [Jeff Trawick]

183 may now be specified to the <File/Directory > container, rather
184 than by vhost. [William Rowe]

187 modules. [William Rowe]
189 *) mod_isapi: Major refactoring of the code to rely on apr internals

191 symbol definitions.) [William Rowe]
193 *) mod_isapi: Fixed the return string length from GetServerVariable
194 callback, it was not including the trailing null in the consumed

264 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
266 *) Close sockets on worker MPM when doing a graceless restart.
269 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
270 as the session id context rather that a MD5 hash of that vhost ID,
271 because it caused very long vhost id's to be unusable with mod_ssl.
272 PR 8572. [Cliff Woolley]
274 *) Fix the link to the description of the CoredumpDirectory
275 directive in the server-wide document. PR 8643. [Jeff Trawick]
277 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
279 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
280 - Avoid SIGBUS on sparc machines with SHMCB session caches
281 - Allow whitespace between the pipe and the name of the
282 program in SSLLog "| /path/to/program". [Cliff Woolley]
284 *) Introduce mod_ext_filter and mod_deflate experimental modules
285 to the Win32 build (zlib sources must be in srclib\zlib.)
288 *) Changes to the worker MPM's queue management and thread
289 synchronization code to reduce mutex contention [Brian Pane]
291 *) Don't install *.in configuration files since we already install
292 *-std.conf files. [Aaron Bannert]
294 *) Many improvements to the threadpool MPM. [Aaron Bannert]
296 *) Fix subreqs that are promoted via fast_redirect from having invalid
297 frec->r structures. This would cause subtle errors later on in
298 request processing such as seen in PR 7966. [Justin Erenkrantz]
300 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
302 *) Modify the worker MPM to not accept() new connections until
303 there is an available worker thread. This prevents queued
304 connections from starving for processing time while long-running
305 connections were hogging all the available threads. [Aaron Bannert]
307 *) Convert the worker MPM's fdqueue from a LIFO back into a FIFO.
310 *) Get basic HTTP proxy working on EBCDIC machines. [Jeff Trawick]

348 ap_uname2id. [Scott Lamb <slamb@slamb.org>]
350 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
352 *) [Security] Added the APLOG_TOCLIENT flag to ap_log_rerror() to
353 explicitly tell the server that warning messages should be sent
354 to the client in addition to being recorded in the error log.
355 Prior to this change, ap_log_rerror() always sent warning
356 messages to the client. In one case, a faulty CGI script caused
357 the server to send a warning message to the client that contained
358 the full path to the CGI script. This could be considered a
359 minor security exposure. [Bill Stoddard]
361 *) mod_autoindex output when SuppressRules was specified would
362 omit the first carriage return so the first item in the list
363 would appear to the right of the column headings instead of
364 underneath them. PR 8016 [David Shane Holden <dpejesh@yahoo.com>]
366 *) Moved the call to apr_mmap_dup outside the error branch so
367 that it would actually get called. This fixes a core dump
368 at init everytime you use the MMapFile directive. PR 8314
371 *) Trigger an error when a LoadModule directive attempts to
372 load a module which is built-in. This is a common error when
373 switching from a DSO build to a static build. [Jeff Trawick]
375 *) Change instdso.sh to use libtool --install everywhere and then
376 clean up some stray files and symlinks that libtool leaves around
377 on some platforms. This gets subversion building properly since
378 it needed a re-link to be performed by libtool at install time,
379 and the old instdso.sh logic to simply cp the DSO didn't handle
380 that requirement. [Sander Striker]
382 *) Allow VPATH builds to succeed when configured from an empty
383 directory. [Thom May <thom@planetarytramp.net>]
385 *) Fix 'control reaches end of non-void function' warning in
386 server/log.c. [Ben Collins-Sussman <sussman@collab.net>]
388 *) Perchild MPM is now correctly deemed as experimental and is now
389 located in server/mpm/experimental. [Justin Erenkrantz]
391 *) Fix segfault in mod_mem_cache when garabge collecting an expired
392 cache entry. [Bill Stoddard]
394 *) Introduced -E startup_logfile_name option to httpd to allow admins
395 to begin logging errors immediately. This provides Win32 users
396 an alternative to sending startup errors to the event viewer, and
397 allows other daemon tool authors an alternative to logging to stderr.
400 *) Fix subreqs with non-defined Content-Types being served improperly.
403 *) Merge in latest GNU config.guess and config.sub files. PR 7818.
406 *) Move 100 - Continue support to the HTTP_IN filter so that filters
407 are guaranteed to support 100 - Continue logic without any

422 Registry or RegistryStrict to override shebang lines, as 1.3 did.
423 PR 8004 [William Rowe]

435 *) Win32: Fix problem that caused rapid performance degradation
436 when number of connecting clients exceeded ThreadsPerChild.
439 *) Fixed a segfault parsing large SSIs on non-mmap systems.
442 *) Proxy was bombing out every second keepalive request, caused by a
443 stray CRLF before the second response's status line. Proxy now
444 tries to read one more line if it encounters a CRLF where it
445 expected a status. PR 10010 [Graham Leggett]
447 *) Deprecated the apr_lock.h API. Please see the following files
448 for the improved thread and process locking and signaling:
449 apr_proc_mutex.h, apr_thread_mutex.h, apr_thread_rwlock.h,

452 *) Change mod_status to use scoreboard accessor functions so it can
453 be used in any MPM without having to be recompiled.

482 *) Fixes for mod_include errors on boundary conditions in which
483 "<!--#" occurs at the very end of a bucket
484 [Paul Reder, Brian Pane]
486 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
487 cause the Apache parent process to run in the foreground (similar to
488 -DNO_DETACH except that it doesn't switch session ids).
491 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
492 for those platforms that support it. If using the default
493 implementation, this is between pthread and sysvsem in priority.
494 This implies it's the new default for Darwin. [Jim Jagielski]
496 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
497 environment variables in the envvars file. [Jeff Trawick]
499 *) worker MPM: Don't create a listener thread until we have a worker
500 thread. Otherwise, in situations where we'll have to wait a while
501 to take over scoreboard slots from a previous generation, we'll be
502 accepting connections we can't process yet. [Jeff Trawick]
504 *) Allow worker MPM to build on systems without pthread_kill().
505 [Pier Fumagalli, Jeff Trawick]
507 *) Prevent ap_add_output_filters_by_type from being called in
508 ap_set_content_type if the content-type hasn't changed.
511 *) Performance: implemented the bucket allocator made possible by the
512 API change in 2.0.34. [Cliff Woolley]
514 *) Don't allow initialization to succeed if we can't get a socket
515 corresponding to one of the Listen statements. [Jeff Trawick]
517 Changes with Apache 2.0.34
519 *) Allow all Perchild directives to accept either numerical UID/GID
520 or logical user/group names. [Scott Lamb <slamb@slamb.org>]
522 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
524 *) implement ssl proxy to support ProxyPass / https:// and the

530 *) Made AB's use of the Host: header rfc2616 compliant
531 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
533 *) The old, legacy (and unused) code in which the scoreboard was totally
534 and completely contained in a file (SCOREBOARD_FILE) has been
535 removed. This does not affect scoreboards which are *mapped* to
536 files using named-shared-memory. [Jim Jagielski]
538 *) Change bucket brigades API to allow a "bucket allocator" to be
539 passed in at certain points. This allows us to implement freelists

555 quick handlers to optionally do a lookup rather than actually
556 serve content. This is the first of several changes required fix
557 several problems with how quick handlers work with subrequests.
560 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
562 *) [APR-related] The ordering of the default accept mutex method has

573 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
575 *) When a proxied site was being served, Apache was replacing
576 the original site Server header with it's own, which is not
577 allowed by RFC2616. Fixed. [Graham Leggett]
579 *) Fix a mod_cgid problem that left daemon processes stranded
580 in some server restart scenarios. [Jeff Trawick]
582 *) Added exp_foo and rel_foo variables to config_vars.mk for
583 all Apache and Autoconf path variables (like --sysconfdir,
584 --sbindir, etc). exp_foo is the "expanded" version, which means
585 that all internal variable references have been interpolated.
586 rel_foo is the same as $exp_foo, only relative to $prefix if they
587 share a common path. [Aaron Bannert]
589 *) Fix some restart/terminate problems in the worker MPM. Don't
590 drop connections during graceful restart. [Jeff Trawick]
592 *) Change the header merging behaviour in proxy, as some headers
593 (like Set-Cookie) cannot be unmerged due to stray commas in
594 dates. [Graham Leggett]

617 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
619 *) mod_dav's APIs for REPORT response handling was changed so that
620 providers can generate the content directly into the output filter
621 stack, rather than buffering the response into memory. [Greg Stein]
623 *) Fix a hang condition with graceful restart and prefork MPM
624 in the situation where MaxClients is very high but
625 much fewer servers are actually started at the time of the
626 restart. [Jeff Trawick]
628 *) Small performance fixes for mod_include [Brian Pane]
630 *) Performance improvement for the error logger [Brian Pane]

633 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
634 according to sun people solaris 8+ doesn't have a thundering
635 herd problem [Ian Holsman]
637 *) Allow URIs specifying CGI scripts to include '/' at the end
638 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
639 which ignore '/' at the end of the names of non-directories).
640 PR 10138 [Jeff Trawick]
642 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and

671 *) Stop installing libtool for APR and tell APR where it should place
672 its copy of libtool (via our installbuildpath layout variable).
675 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
676 when reading from a remote HTTP server in proxy. [Graham Leggett]
678 *) Modify receive/send loop in proxy_http and proxy_ftp so that
679 should it be necessary, the remote server socket is closed before
680 transmitting the last buffer (set by ProxyIOBufferSize) to the
681 client. This prevents the backend server from being forced to hang
682 around while the last few bytes are transmitted to a slow client.
683 Fix the case where no error checking was performed on the final
684 brigade in the loop. [Graham Leggett]
686 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
687 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
688 hours. [Graham Leggett, Bill Stoddard]

691 for a undefined variable. [Ian Holsman]
693 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS

711 Changes with Apache 2.0.33
713 *) Fix a problem in the new --enable-layout functionality where
714 it wouldn't allow overrides from variables like --prefix,
715 --bindir, etc. [Thom May <thom@planetarytramp.net>]
717 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
718 no longer hangs around waiting for the socket to close before
719 returning exhaustive data. [Aaron Bannert]
721 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
722 [Thom May <thom@planetarytramp.net>]
724 *) Change mod_ssl to always do a full startup/teardown on restarts.
725 this allows mod_ssl to be added to a server that is already
726 running and makes it possible to add/change certs/keys after the
727 server has been started. [Doug MacEachern]
729 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
730 This pipe must be a bidirectional 'console' style relay, which
731 mod_ssl prints all prompts to the pipe's stdin, and reads the
732 passphrases from the pipe's stdout. [William Rowe]
734 *) Fix bug where --sysconfdir and --localstatedir were being
735 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
738 *) Fix --enable-layout to work again. Caution: When specifying
739 --enable-layout, common arguments like --prefix, --exec-prefix,
740 etc. will be ignored and the settings from the layout will be
741 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
744 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
745 regex pattern matching for the determination of which requests
746 to use the remote proxy for. [Jim Jagielski]
748 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
750 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
751 cruft in piped logs and rewritemap child processes.
754 *) All instances of apr_lock_t have been removed and converted
755 to one of the following new lock APIs: apr_thread_mutex.h,
756 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
757 use the apr_lock.h API, as the old API will soon be deprecated.
760 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
761 [Ralf S. Engelschall, Cliff Woolley]
763 *) mod-include: make it handle flush'es and fix the 'false-alarm'
764 [Justin Erenkrantz, Brian Pane, Ian Holsman]
766 *) ap_get_*_filter_handle() functions to allow 3rd party modules
767 to lookup filter handles so they can bypass the filter name
768 lookup when adding filters to a request (via ap_add_*_filter_handle())
769 [Ryan Morgan <rmorgan@covalent.net>]
771 *) Fix for multiple file buckets on Win32, where the first file
772 bucket would cause the immediate closure of the socket on any
773 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
775 *) Correct Win32 failure of mmap of a segment beyond start of the
776 file; fixes large SSL and similar transfers. [William Rowe]
779 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
780 multi-process mode to not "daemonize" while detaching from the
781 controlling terminal. This is necessary for Apache to work with
782 process-management tools like AIX's "System Resource Controller"
783 as well as Dan Bernstein's "daemontools".

789 *) fix bug in mod-include where it wouldn't send a unmatched
790 part if it was at the end of a bucket [Ian Holsman]
792 *) worker MPM: Improve logging of errors with the interface between
793 the listener thread and worker threads. [Jeff Trawick]
795 *) Some browsers ignore cookies that have been merged into a
796 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
797 are now unmerged in the http proxy before being sent to the
798 client. [Graham Leggett]
800 *) Fix a problem with proxy where each entry of a duplicated
801 header such as Set-Cookie would overwrite and obliterate the
802 previous value of the header, resulting in multiple header
803 values (like cookies) going missing.
804 [Graham Leggett, Joshua Slive]

829 *) Fix segfault and display error when SSLMutex file can not be
830 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
832 *) Add reference counting to mod_mem_cache cache objects to
833 better manage removing objects from the cache.
836 *) Change the verbage on the ScoreBoardFile in our default configs.
837 Also change the default to be commented out (unspecified) so we
838 get anonymous shared memory by default. [Aaron Bannert]
840 *) Implement new ScoreBoardFile directive logic. This affects how
841 we create the scoreboard's shared memory segment. If the directive
842 is present, a name-based segment is created. If the directive is
843 not present, first an anonymous segment is created, and if that
844 fails, a name-based segment is created from a file of the name
845 DEFAULT_SCOREBOARD. This gives third-party applications the
846 ability to access our scoreboard. [Aaron Bannert]
848 *) Allow mod_deflate to work with non-GET requests and properly send
849 Content-Lengths. [Sander Striker <striker@apache.org>]
851 *) Fix ap_directory_merge() to correctly merge configs when there is
852 no <Directory /> block. [Justin Erenkrantz, William Rowe]
854 *) Remove spurious debug messsages that are normal under HTTP
855 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
857 *) Fix a bug in mod_cgid that would prevent proper shutdown death
858 of the cgid process. [Aaron Bannert]
860 *) Add signal handling back in to the worker MPM for the one_process
861 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
863 *) Performance: Reuse per-connection transaction pools in the
864 worker MPM, rather than destroying and recreating them. [Brian Pane]
866 *) Remove all signals from the worker MPM's child process. Instead,
867 the parent uses the Pipe of Death for all communication with the
868 child processes. [Ryan Bloom]
870 Changes with Apache 2.0.32
872 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
873 default if the directive is not specified. This mirrors older
874 behavior without changes to the httpd.conf. [William Rowe]
876 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
877 the service, mpm and logging code, and bugs in apr_file_open_stderr
878 and apr_file_dup2 functions. Win2K/XP services have no handles
879 associated for stdin/out/err, which caused unpredictable behavior
880 in the prior release. [William Rowe, Bill Stoddard]
882 *) Win32: simplify the Application Event Log messages, since there isn't
883 likely to be 'more information in the error log' before an error log
884 has been opened. [William Rowe]
886 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
887 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
889 *) Win32: apache -k shutdown now behaves like apache -k stop.
892 *) Fix prefork to not kill the parent if a child hits a resource shortage
893 on accept(). [Greg Ames]
895 *) Fix seg faults that occur when what should be the httpd request line
896 starts with \r\n followed by garbage. [Greg Ames]
898 *) Allow statically linked support binaries with the new
899 --enable-static-support flag, and enable this behavior in
900 the binbuild script. Also add a new --enable-static-htdbm
901 flag. [Aaron Bannert]
903 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
904 do only one stat() call when generating the directory listings.
907 *) Fix resolve_symlink to save the original symlink name if known.
910 *) Be a bit more sane with regard to CanonicalNames. If the user has
911 specified they want to use the CanonicalName, but they have not
912 configured a port with the ServerName, then use the same port that
913 the original request used. [Ryan Bloom and Ken Coar]
915 *) In core_input_filter, check for an empty brigade after
916 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
917 client says it will post some data but we get FIN before any
918 data arrives. [Jeff Trawick]
920 *) Not being able to bind to the socket is a fatal error. We should
921 print an error to the console, and return a non-zero status code.
922 With these changes, all of the Unix MPMs do that correctly.
925 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
926 through to CGI scripts. PR 9163
927 [Brian Reid <breid@customlogic.com>,
928 Zvi Har'El <rl@math.technion.ac.il>]
930 *) binbuild.sh: Make sure that we use the expat from our source
931 tree so that there aren't any surprises on the target machine.
934 *) mod_cgid: Add retry logic for when the daemon can't fork fast
935 enough to keep up with new requests. Start using
936 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
937 when we can't talk to the daemon. [Jeff Trawick]
939 *) apxs: LTFLAGS envvar can override default libtool options. Try
940 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
941 the covers. [Jeff Trawick]
943 *) The Location: response header field, used for external
944 redirect, *must* be an absoluteURI. The Redirect directive
945 tested for that, but RedirectMatch didn't -- it would allow
946 almost anything through. Now it will try to turn an abs_path
947 into an absoluteURI, but it will correctly varf like Redirect
948 if the final redirection target isn't an absoluteURI. [Ken Coar]
950 Changes with Apache 2.0.31
952 *) Create the scoreboard (in the parent) in a global pool context,
953 so it survives graceful restarts. This fixes a SEGV during
954 graceful restarts. [Aaron Bannert]
956 *) Add a timeout option to the proxy code 'ProxyTimeout'
959 *) FTP directory listings are now always retrieved in ASCII mode.
960 The FTP proxy properly escapes URI's and HTML in the generated
961 listing, and escapes the path components when talking to the FTP
962 server. It is now possible to browse the root directory by using
963 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
964 Also, the last path component may contain wildcard characters
965 '*' and '?', and if they do, a directory listing is created instead
966 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
969 *) Added single-listener unserialized accept support to the
970 worker MPM [Brian Pane]
972 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
973 the incoming host header through to the proxied server
974 [Geoff <g.russell@ieee.org>]
976 *) New Directive Option for ProxyPass. It now can block a location
977 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
979 *) Don't let the default handler try to serve a raw directory. At
980 best you get gibberish. Much worse things can happen depending
981 on the OS. [Jeff Trawick]
983 *) Change the pre_config hook to return a value. Modules can now emit
984 an error message and then cause the server to quit gracefully during
985 startup. This required a bump to the MMN. [Aaron Bannert]
987 *) Fix some unix socket descriptor leaks in the handler side of
988 mod_cgid (the part that runs in the server process). Whack a
989 silly "close(-1)" in the handler too. [Jeff Trawick]
991 *) Change the pre_mpm hook to return a value, so that scoreboard
992 init errors percolate up to code that knows how to exit
993 cleanly. This required a bump to the MMN. [Jeff Trawick]
995 *) Add the socket back to the conn_rec and remove the create_connection
996 hook. The create_connection hook had a design flaw that did not
997 allow creating connections based on vhost info. [Bill Stoddard]
999 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
1000 Resolves the common case of using negotation to resolve the request
1001 /script/foo for /script.cgi/foo. [William Rowe]
1003 *) Added new functions ap_add_(input|output)_filter_handle to
1004 allow modules to bypass the usual filter name lookup when
1005 adding hard-coded filters to a request [Brian Pane]
1007 *) caching should now work on subrequests (still very experimental)
1010 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
1012 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
1015 *) Refactor ap_rgetline so that it does not use an internal brigade.
1016 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
1018 *) Remove mod_auth_db. [Justin Erenkrantz]
1020 *) Do not install unnecessary pcre headers like config.h and internal.h.
1021 [Joe Orton <joe@manyfish.co.uk>]
1023 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
1024 (as it does for a normal request). quick_handled sub-requests now work
1025 in mod-include [Ian Holsman]
1027 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
1028 'CONTENT' one, as it needs to run AFTER all content headers
1030 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
1033 *) Split out blocking from the mode in the input filters.
1036 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
1038 *) Cause Win32 to capture all child-worker process errors in
1039 Apache to the main server error log, until the child can
1040 open its own error logs. [William Rowe]
1042 *) HPUX 11.*: Do not kill the child process when accept()
1043 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
1044 by [madhusudan_mathihalli@hp.com])
1047 *) Fix a problem in the parsing of the <Proxy foo> directive.
1050 *) rewrite of mod_ssl input filter for better performance and less
1051 memory usage [Doug MacEachern]
1053 *) allow quick_handler to be run on subrequests. [Ian Holsman]
1055 *) mod_dav now asks its provider to place content directly into the
1056 filter stack when handling a GET request. The mod_dav/provider
1057 API has changed, so providers need to be updated. [Greg Stein]
1059 *) Clear the output socket descriptor in unixd_accept() to make sure
1060 we don't supply a bogus socket to the caller if the accept fails.
1061 This caused problems with the worker MPM, which tried to process
1062 the returned socket if it was non-NULL. [Brian Pane]
1064 *) Move a check for an empty brigade to the start of core input filter
1065 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
1067 *) Add FileETag directive to allow configurable control of what
1068 data are used to form ETag values for file-based URIs. MMN
1069 bumped to 20020111 because of fields added to the end of
1070 the core_dir_config structure. [Ken Coar]
1072 *) Fix a segfault in mod_rewrite's logging code caused by passing the
1073 wrong config to ap_get_remote_host(). [Jeff Trawick]
1075 *) Allow mod_cgid to work from a binary distribution install by
1076 using 755 for the permissions on the log directory instead of
1079 *) Fixed a segfault that happened during graceful shutdown (or when
1080 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
1082 *) Split all Win32 modules [excluding the core components mod_core,
1083 mod_so, mod_win32 and the winnt mpm] into individual loadable
1084 modules, so the administrator may individually disable the former
1085 compiled-in modules by simply commenting out their LoadModule
1086 directives. [William Rowe]
1088 *) Saved Win32 module authors and porters many future headaches, by
1089 duplicating the appropriate .h files such as os.h into the include
1090 directory, including in the build tree. [William Rowe]
1092 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
1093 Use SSL functions/macros instead of directly dereferencing SSL
1094 structures wherever possible.
1095 Add type-casts for the cases where functions return a generic pointer.
1096 Add $SSL/include to configure search path.
1097 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1099 *) Moved several pointers out of the shared Scoreboard so it is
1100 more portable, and will present the vhost name across server
1101 generation restarts. [William Rowe]
1103 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
1106 Changes with Apache 2.0.30
1108 *) Fix the main bug for FreeBSD and threaded MPM's. There are
1109 still issues (see STATUS) but at least the server will now
1110 run without crashing the machine.
1111 [David Reid, Aaron Bannert, Justin Erenkrantz]
1113 *) Fix a typo in mod_deflate's m4 config section.
1114 [albert chin (china@thewrittenword.com)]
1116 *) Fix a couple of mod_proxy problems forwarding HTTP connections
1117 and handling CONNECT:
1118 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
1119 (2) Proxy failed to connect when the first IP address returned by
1120 the resolver was unreachable but a secondary IP address was.
1123 *) Fix the module identifer as shown in the docs for various core
1124 modules (e.g., the identifer for mod_log_config was previously
1125 listed as config_log_module). PR #9338
1126 [James Watson <ap2bug@sowega.org>]
1128 *) Fix LimitRequestBody directive by placing it in the HTTP
1129 filter. [Justin Erenkrantz]
1131 *) Fix mod_proxy seg fault when the proxied server returns
1132 an HTTP/0.9 response or a bogus status line.
1135 *) Prevent mod_proxy from truncating one character off the
1136 end of the status line returned from the proxied server.
1137 [Adam Sussman, Bill Stoddard]
1139 *) Eliminate loop in ap_proxy_string_read().
1140 [Adam Sussman, Bill Stoddard]
1142 *) Provide $0..$9 results from mod_include regex parsing.
1145 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
1147 *) Introduced the ForceLanguagePriority directive, to prevent
1148 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
1149 when using Multiviews. [William Rowe]
1151 *) Fix a problem which prevented mod_cgid and suexec from working
1152 together reliably [Greg Ames]
1154 *) Remove the call to exit() from within mod_auth_digest's post_config
1155 phase. [Aaron Bannert]
1157 *) Fix a problem in mod_auth_digest that could potentially cause
1158 problems with initialized static data on a system that uses DSOs.
1161 *) Fix a segfault in the worker MPM that could happen during
1162 child process exits. [Brian Pane, Aaron Bannert]
1164 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
1166 *) Fix matching of vhosts by ip address so we find IPv4
1167 vhost address when target address is v4-mapped form of
1168 that address. [Jeff Trawick]
1170 *) More performance tweaks to the BNDM string-search algorithm
1171 used to find "<!--#" tokens in mod_include [Brian Pane]
1173 *) Miscellaneous small performance fixes: optimized away various
1174 string copy operations and removed large temp buffers from
1175 the stack [Brian Pane]
1177 *) Fixed startup segfault that occurred when a VirtualHost
1178 directive had a port but no address [Brian Pane]
1180 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
1182 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
1183 if oslevel < WINNT. This should fix several problems reported
1184 Against 2.0.28 on Windows 98 [Bill Stoddard]
1186 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
1187 to fail. [Bill Stoddard]
1189 *) Change core code to allow an MPM to set hard thread/server
1190 limits at startup. prefork, worker, and perchild MPMs now have
1191 directives to set these limits. [Jeff Trawick]
1193 *) Win32: The async AcceptEx() event should be autoreset upon
1194 successful completion of a wait (WaitForSingleObject). This
1195 eliminates a number of spurious
1196 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
1199 *) Move any load library path environment variables out of
1200 apachectl and into a separate environment variable file which
1201 can be more easily tailored by the admin. The environment
1202 variable file as built by Apache may have additional system-
1203 specific settings. For example, on OS/390 we tailor the heap
1204 settings to allow lots of threads. [Jeff Trawick]
1206 *) Use the new APR pool code to reduce pool-related lock
1207 contention in the worker MPM. [Sander Striker]
1209 *) The POD no longer assumes the child is listening on 127.0.0.1
1210 and now pulls the first hostname in the list of listeners to
1211 perform the dummy connect on. This fixes a bug when the user
1212 had configured the Listen directive for an IP other than
1213 127.0.0.1. This would result in undead children and error
1214 messages such as "Connection refused: connect to listener".
1217 *) The worker MPM now respects the LockFile setting, needed to
1218 avoid locking problems with NFS. [Jeff Trawick]
1220 *) Fix segfault when worker MPM receives SIGHUP.
1221 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
1223 *) Fix bug that could potentially prevent the perchild MPM from
1224 working with more than one vhost/uid. [Aaron Bannert]
1226 *) Change make install and apxs -i processing of DSO modules to
1227 perform special handling on platforms where libtool doesn't install
1228 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
1229 which prevented standard LoadModule statements from working.
1232 *) Whenever mod_so is enabled (not just when there are DSOs for
1233 our modules), do whatever special magic is required for compiling/
1234 loading third-party modules. This allows third-party DSOs to
1235 be used on an AIX build when there were no built-in modules
1236 built as DSOs. (This should help on OS/390 and BeOS as well.)
1239 *) Allow apxs to be used to build DSOs on AIX without requiring the
1240 user to hard-code the list of import files. (This should help
1241 on OS/390 and BeOS as well.) [Jeff Trawick]
1243 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
1244 PR 8563, 8919 [William Rowe]
1246 *) Get binary builds working when libapr and libaprutil are built
1249 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
1250 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
1251 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
1253 *) Fix the handling of SSI directives in which the ">" of the
1254 terminating "-->" is the last byte in a file [Brian Pane]
1256 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
1257 message that we had back in apache-1.3 and still have scattered
1258 throughout our docs. [Aaron Bannert]
1260 *) Prevent the Win32 port from continuing after encountering an
1261 error in the command line args to apache. [William Rowe]
1263 *) On a error in the proxy, make it write a line to the error log
1266 *) Various mod_ssl performance improvements [Doug MacEachern]
1268 Changes with Apache 2.0.29
1270 *) Add buffering in core_output_filter to ensure that long
1271 lists of small buckets don't cause small packet writes.
1272 [Brian Pane, Ryan Bloom]
1274 *) Fix the installation target to make sure that the manual is
1275 installed in the correct location.
1276 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
1277 Gomez Henri <hgomez@slib.fr>]
1279 *) Fix the cmd command for mod_include. When we are processing
1280 a cmd command, we do not want to use the r->filename to set
1281 the command name. The command comes from the SSI tag. To do this,
1282 I added a variable to the function that builds the command line
1283 in mod_cgi. This allows the include_cmd function to specify
1284 the command line itself. [Ryan Bloom]
1286 *) Change open_logs hook to return a value, allowing you
1287 to flag a error while opening logs
1288 [Ian Holsman, Doug MacEachern]
1290 *) Change post_config hook to return a value, allowing you
1291 to flag a error post config
1292 [Ian Holsman, Jeff Trawick]
1294 *) Allow SUEXEC_BIN (the path to the suexec binary that is
1295 hard-coded into the server) to be specified to the configure
1296 script by the --with-suexec-bin parameter. [Aaron Bannert]
1298 *) Fix segv in worker MPM following accept on pipe-of-death
1301 *) Add mod_deflate to experimental.
1302 [Ian Holsman, Justin Erenkrantz]
1304 *) Bail out at configure time if an invalid MPM was specified.
1305 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1307 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
1308 configured [John Sterling <sterling@covalent.net>]
1310 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
1312 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
1314 *) Optimization for the BNDM string-search function in
1315 mod_include. [Brian Pane]
1317 *) Fixed the behavior of the XBitHack directive.
1318 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
1320 *) The threaded MPM for Unix has been removed. Use the worker
1321 MPM instead. [various]
1323 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
1324 in logging the error from a failed DNS lookup. [Jeff Trawick]
1326 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
1329 *) Get mod_cgid killed when a MPM exits due to a fatal error.
1332 *) Fix a file descriptor leak in mod_include. When we include a
1333 file, we use a sub-request, but we didn't destroy the sub-request
1334 immediately, instead we waited until the original request was
1335 done. This patch closes the sub-request as soon as the data is
1336 done being generated. [Brian Pane <bpane@pacbell.net>]
1338 *) Allow modules that add sockets to the ap_listeners list to
1339 define the function that should be used to accept on that
1340 socket. Each MPM can define their own function to use for
1341 the accept function with the MPM_ACCEPT_FUNC macro. This
1342 also abstracts out all of the Unix accept error handling
1343 logic, which has become out of synch across Unix MPMs.
1346 *) Fix a bug which would cause the response headers to be omitted
1347 when sending a negotiated ErrorDocument because the required
1348 filters were attached to the wrong request_rec.
1349 [John Sterling <sterling@covalent.net>]
1351 *) Remove commas from the end of the macros that define
1352 directives that are used by MPMs. Prior to this patch,
1353 you would use these macros without commas, which was unlike
1354 the macros for any other directives. Now, the caller provides
1355 the comma rather than the macro providing it. This makes
1356 the macros look more like the rest of the directives.
1357 [Ryan Bloom and Cliff Woolley]
1359 *) Add 'redirect-carefully' environment option to disable sending
1360 redirects under special circumstances. This is helpful for
1361 Microsoft's WebFolders when accessing a directory resource via
1362 DAV methods. [Justin Erenkrantz]
1364 *) Begin to abstract out the underlying transport layer.
1365 The first step is to remove the socket from the conn_rec,
1366 the server now lives in a context that is passed to the
1367 core's input and output filters. This forces us to be very
1368 careful when adding calls that use the socket directly,
1369 because the socket isn't available in most locations.
1372 *) Really reset the MaxClients value in worker and threaded
1373 when the configured value is not a multiple of the number
1374 of threads per child. We said we did previously but we
1375 forgot to. [Jeff Trawick]
1377 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
1379 *) If shared modules are requested and mod_so is not available,
1380 produce a fatal config-time error. [Justin Erenkrantz]
1382 *) Improve http2env's performance by cutting the work it has to
1383 do. [Brian Pane <bpane@pacbell.net>]
1385 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
1386 [Brian Pane <bpane@pacbell.net>]
1388 Changes with Apache 2.0.28
1390 *) Fix infinite loop in mod_cgid.c.
1391 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
1393 *) When no port is given in a "ServerName host" directive, the
1394 server_rec->port is now set to zero, not 80. That allows for
1395 run-time deduction of the correct server port (depending on
1396 SSL/plain, and depending also on the current setting of
1397 UseCanonicalName). This change makes redirections
1398 work, even with https:// connections. As in Apache-1.3, the
1399 connection's actual port number is never used, only the ServerName
1400 setting or the client's Host: setting. Documentation updated
1401 to reflect the change. [Martin Kraemer]
1403 *) Add a '%{note-name}e' argument to mod-headers, which works in
1404 the same way as mod_log_confg. [Ian Holsman]
1406 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
1407 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
1408 MPMs. [Cliff Woolley]
1410 *) Introduce htdbm, a user management utility for db/dbm authorization
1411 databases. [Mladen Turk <mturk@mappingsoft.com>]
1413 *) Optimize usage of strlen and strcat in ap_directory_walk.
1414 [Brian Pane <bpane@pacbell.net>]
1416 Changes with Apache 2.0.27
1418 *) Introduce an Apache mod_ssl initial configuration template
1419 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
1421 *) Fixed a memory leak in the getline parsing code that could
1422 be triggered by arbitrarily large header lines. Requests
1423 from the core input filter for single lines are now limited
1424 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
1426 *) Fix a truncation bug in how we print the port on the Via: header.
1427 The routine that prints the Via: header now takes a length for
1428 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
1430 *) Some syntax errors in mod_mime_magic's magic file can result
1431 in a 500 error, which previously was unlogged. Now we log the
1432 error. [Jeff Trawick]
1434 *) Add the support/checkgid helper app, which checks the run-time
1435 validity of group identifiers usable in the Group directive.
1438 *) Various --enable-so options have been fixed: --enable-so is
1439 treated as "static"; explicit --enable-so=shared issues an error;
1440 and explicit --enable-so fails with error on systems without
1441 APR_HAS_DSO. [Aaron Bannert]
1443 *) Fix a segfault in the core input filter when the client socket
1444 gets disconnected unexpectedly. [Cliff Woolley]
1446 *) Fix the reporting for child processes that die. This removes
1447 all of the non-portable W* macros from Apache.
1448 [Jeff Trawick and Ryan Bloom]
1450 *) Win32: Track and display "Parent Server Generation:" in
1451 mod_status output. The generation will be bumped at
1452 server graceful restart, when the child process exits
1453 by hitting MaxRequestsPerChild or if the child
1454 process exits abnormally. [Bill Stoddard]
1456 *) Win32: Fix problem where MaxRequestsPerChild directive was
1457 not being picked up in favor of the default. Enable
1458 the parent to start up a new child process immediately upon
1459 the old child starting shutdown.
1462 *) Fix some bungling of the remote port in rfc1413.c so that
1463 IdentityCheck retrieves the proper user id instead of failing
1464 and thus always returning "nobody."
1465 [Dick Streefland <Dick.Streefland@xs4all.nl>]
1467 *) Introduced thread saftey for mod_rewrite's internal cache.
1468 [Brian Pane <bpane@pacbell.net>]
1470 *) Simplified mod_env's directives to behave as most directives are
1471 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
1472 directive following that UnsetEnv within the same container.
1473 Also provides a runtime startup warning if a PassEnv configured
1474 environment value is undefined. [William Rowe]
1476 *) The worker MPM is now completely ported to APR's new lock API. It
1477 uses native APR types for thread mutexes, cross-process mutexes,
1478 and condition variables. [Aaron Bannert]
1480 *) Sync up documentation to remove all references to the now deprecated
1481 Port directive. [Justin Erenkrantz]
1483 *) Moved all ldap modules from the core to httpd-ldap sub-project
1486 *) Exit when we can't listen on any of the configured ports. This
1487 is the same behavior as 1.3, and it avoids having the MPMs to
1488 deal with bogus ap_listen_rec structures. [Jeff Trawick]
1490 *) Cleanup the proxy code that creates a request to the origin
1491 server. This change adds an optional hook, which allows modules
1492 to gain control while the request is created if the proxy module
1493 is loaded. The purpose of this hook is to allow modules to add
1494 input and/or output filters to the request to the origin. While
1495 I was at it, I made the core use this hook, so that proxy request
1496 creation uses some of the code from the core. This can still be
1497 greatly improved, but this is a good start. [Ryan Bloom]
1499 Changes with Apache 2.0.26
1501 *) Port the MaxClients changes from the worker MPM to the threaded
1504 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
1505 with the new input filtering system. [Justin Erenkrantz]
1507 *) Introduce the MultiviewsMatch directive, to allow the operator
1508 to be flexible in recognizing Handlers and Filters filename
1509 extensions as part of the Multiviews matching logic, strict with
1510 MultiviewsMatch NegotiatedOnly to accept only filename extentions
1511 that designate negotiated parameters, (content type, charset, etc.)
1512 or MultiviewsAll for the 1.3 behavior of matching any files, even
1513 if they have unregistered extensions. [William Rowe]
1515 *) Fixed the configure script to add a LoadModule directive to
1516 the default httpd.conf for any module that was compiled
1517 as a DSO. [Aaron Bannert <aaron@clove.org>]
1519 *) rewrite mod_ssl input filtering to work with the new input filtering
1520 system. [Justin Erenkrantz]
1522 *) prefork: Don't segfault when we are able to listen on some but
1523 not all of the configured ports. [Jeff Trawick]
1525 *) Build mod_so even if no core modules are built shared.
1526 [Aaron Bannert <aaron@clove.org>]
1528 *) Introduce ap_directory_walk rewrite (with further optimizations
1529 required) to adapt to the ap_process_request_internal() changes.
1530 Optimized so subrequests and redirects now reuse previous section
1531 merges, until we mismatch with the original directory_walk, and
1532 precomputed r->finfo results will cause directory_walk to skip
1533 the most expensive phases of the function. [William Rowe]
1535 *) Allow ApacheMonitor to connect to and control Apache on other
1536 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
1538 *) Remove the Port directive. In it's place, the Listen directive
1539 is now a required directive, which tells Apache what port to
1540 listen on. The ServerName directive has also been extended
1541 to accept an optional port. If the port is specified to the
1542 ServerName, the server will report that port whenever it
1543 reports the port that it is listening on. This change was
1544 made to ease configuration errors that stem from having a Port
1545 directive, and a Listen directive. In that situation, the server
1546 would only listen to the port specified by the Listen command,
1547 which caused a lot of confusion to users. [Ryan Bloom]
1549 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
1550 build, as loadable modules. [William Rowe]
1552 *) Fix --enable-mods-shared processing. If most is specified,
1553 then all modules that can be compiled as shared modules are.
1554 [Aaron Bannert <aaron@clove.org>]
1556 *) Update the mime.types file to map video/vnd.mpegurl to mxu
1557 and add commonly used audio/x-mpegurl for m3u extensions.
1558 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
1560 *) Eliminate the depreciated r->content_language, in favor of the array
1561 r->content_languages introduced many years ago. Module authors must
1562 substantially overhaul their modules, so this needs to be upgraded
1563 if the module still relied on backwards-brokeness. [William Rowe]
1565 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
1568 *) Rewrite the input filtering mechanisms to consolidate and reorganize
1569 code. In short, core_input_filter does something now and
1570 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
1572 *) Update the Win32 build to re-absorb mod_proxy and family.
1575 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
1576 current SDK.) [William Rowe]
1578 *) Some style changes to the code that does ProxyErrorOverride. Fixed
1579 config merge behaviour. [Graham Leggett]
1581 *) Allow support programs to be compiled against a static version
1582 of libapr. This allows the smaller support programs to be
1583 relocated. [Aaron Bannert <aaron@clove.org>]
1585 *) Update the mime.types file to the registered media types as
1586 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
1588 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
1589 number of clients that can connect at the same time, instead of
1590 specifying the maximum number of child processes.
1591 [Aaron Bannert <aaron@clove.org>]
1593 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
1594 be consistent with 1.3. [Justin Erenkrantz]
1596 *) Cache apr_explode_localtime() value for 15 seconds.
1597 [Brian Pane <bpane@pacbell.net>]
1599 *) Fix mod_include to not return ETag or Last-Modified headers.
1600 [Ian Holsman <ianh@cnet.com>]
1602 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
1604 *) Eliminate the wasteful run-time conversion of method names from strings
1605 to numbers in places where the methods are known at compile time.
1606 [Brian Pane <bpane@pacbell.net>]
1608 *) Turn the worker MPM's queue into a LIFO. This may
1609 improve cache-hit performance under some conditions.
1610 [Aaron Bannert <aaron@clove.org>]
1612 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
1613 support it. [Justin Erenkrantz]
1615 *) Cleanup the worker MPM. We no longer re-use transaction
1616 pools. This incurs less overhead than shuffling the pools
1617 around so that they can be re-used. Remove one of the
1618 queue's condition variables. We just redefined the API to
1619 state that you can't try to add more stuff than you allocated
1620 segments for. [Aaron Bannert <aaron@clove.org>]
1622 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
1624 *) Fixed persistent connections when a request contains a body.
1627 *) mod_dav uses a new API to speak to the backend provider for dead
1628 property management. [Greg Stein]
1630 *) Remove the Win32 script-processing exception from mod_cgi, and
1631 roll build_command_line/build_argv_list into a unified, overrideable
1632 ap_cgi_build_command optional function. [William Rowe]
1634 *) Rewrite find_start_sequence to use a better search algorithm
1635 to find the start tag. [Justin Erenkrantz]
1637 *) Fix a seg fault in mod_include. When we are generating an
1638 internal redirect, we must set r->uri to "", not a bogus
1639 string, and not NULL. [Ryan Bloom]
1641 *) Optimized location_walk, so subrequests, redirects and second passes
1642 now reuse previous section merges on a <Location > by <Location >
1643 basis, until we mismatch with the original location_walk.
1646 *) Back out the 1.45 change to util_script.c. This change made
1647 us set the environment variable REQUEST_URI to the redirected
1648 URI, instead of the originally requested URI.
1649 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1651 *) Make mod_include do lazy evaluation of potentially expensive to
1652 compute variables. [Brian Pane <bpane@pacbell.net>]
1654 *) Fix logging of bytes sent for HEAD requests. %b and %B should
1655 log either - or 0, before this patch, they were both logging
1656 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1658 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
1659 than per character. [Brian Pane <bpane@pacbell.net>]
1661 *) Normalize the primary request, redirects and sub-requests to
1662 run the same ap_process_request_internal for consistency in
1663 robustness, behavior and security. [William Rowe]
1665 *) Fix a segfault with mod_include when r->path_info is not set
1666 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
1668 *) Add -X functionality back. This indicates to all MPMs and any other
1669 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
1671 *) Some initial support for the cygwin platform [prefork only].
1672 This is not to be confused with support for the WinNT/Win32
1673 platform, which is the recommended configuration for native
1674 Win32 users. The cygwin platform support is recommended for
1675 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
1677 *) Changed syntax of Set{Input|Output}Filter. The list of filters
1678 must be semicolon delimited (if more than one filter is given.)
1679 The Set{Input|Output}Filter directive now overrides a parent
1680 container's directive (e.g. SetInputFilter in <Directory /web/foo>
1681 will override any SetInputFilter directive in <Directory /web>.)
1682 This new syntax is more consistent with Add{Input|Output}Filter
1683 directives defined in mod_mime. Also cures a bug in prior releases
1684 where the Set{Input|Output}Filter directive would corrupt the
1685 global configuration if the multiple directives were nested.
1688 *) Cured what's ailed mime for quite some time. If an AddSomething
1689 was given in the configuration (Language, Charset, Handler or
1690 Encoding) Apache would set the content type as given by AddType,
1691 but refused to check the mime.types file if AddType wasn't given
1692 for that specific extension. Setting the AddHandler for .html
1693 without setting the AddType text/html html would cause Apache to
1694 use the default content type. [William Rowe]
1696 *) Added some bulletproofing to memory allocation in the LDAP cache
1697 code. [Graham Leggett]
1699 Changes with Apache 2.0.25
1701 *) Move the installed /manual directory out of the /htdocs/ tree, so
1702 that it can be kept more independently from the remaining document
1703 root. The "Alias /manual ..." already allowed for easy projection
1704 into existing private document trees. [Martin Kraemer]
1706 *) Add specified user attributes to the environment when using
1707 mod_auth_ldap. This allows you to use mod_include to embed specified
1708 user attributes in a page like so:
1709 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
1712 *) Fix a performance problem with the worker MPM. We now create
1713 transaction pools once, and re-use them for each connection.
1714 [Aaron Bannert <aaron@clove.org>]
1716 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
1717 of a 'handler' or 'filter', so that any filename extension that does
1718 not contribute to the negotiated metadata can't be served without
1719 an explicit request. E.g., if the .Z extension is associated with
1720 an unzip filter, the user request somefile.Z.html, mod_negotiation
1721 won't serve it. It can serve somefile.Z.html when somefile.Z is
1722 requested, since the .Z extension is explictly requested, if the
1723 .html extension is associated with ContentType text/html.
1726 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
1727 and corresponding AddOutputFilter syntax, to insert one or more
1728 filters by mod_mime filename extension processing.
1731 *) Fix a growing connection pool in core_output_filter() for
1732 keepalive requests. [Jeff Trawick]
1734 *) Moved split_and_pass_pretag_buckets back to being a
1735 macro at Ryans's request. Removed the return from it
1736 by setting and returning a return code instead. Updated
1737 the code to check the return code from the macro and
1738 do the right thing. [Paul J. Reder]
1740 *) Fix a segfault when a numeric value was received for Host:.
1743 *) Add a function ap_remove_input_filter. This is to match
1744 up with ap_remove_output_filter. [Ryan Bloom]
1746 *) Clean up location_walk, so that this step performs a minimum
1747 amount of redundant effort (it must be run twice, but it will no
1748 longer reparse all <Location > blocks when the request uri
1749 hadn't changed.) [William Rowe]
1751 *) Eliminate proxy: (and all other 'special') processing from the
1752 ap_directory_walk() phase. Modules that want to use special
1753 walk logic should refer to the mod_proxy map_to_location example,
1754 with it's proxy_walk and proxysection implementation. This makes
1755 either directory_walk flavor much more legible, since that phase
1756 only runs against real <Directory > blocks.
1759 *) Fix a security problem in mod_include which would allow
1760 an SSI document to be passed to the client unparsed.
1761 [Cliff Woolley, Brian Pane]
1763 *) Introduce the map_to_storage hook, which allows modules to bypass
1764 the directory_walk and file_walk for non-file requests. TRACE
1765 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
1766 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
1769 *) Add the ability for mod_include to add the INCLUDES filter
1770 if the file is configured for the server-parsed handler.
1771 This makes the configuration for .shtml files much easier
1772 to understand, and allows mod_include to honor Apache 1.3
1773 config files. Based on Doug MacEachern's patch to PHP
1774 to do the same thing. [Ryan Bloom]
1776 *) force OpenSSL to ignore process local-caching and to always
1777 get/set/delete sessions using mod_ssl's callbacks
1778 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1779 Geoff Thorpe <geoff@geoffthorpe.net>]
1781 *) Make the worker MPM shutdown and restart cleanly. This also
1782 cleans up some race conditions, and gets the worker using
1783 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
1785 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
1787 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1789 *) Fix for mod_include. Ryan's patch to check error
1790 codes put a return in the wrong place. Also, the
1791 include handler return code wasn't being checked.
1792 I don't like macros with returns, so I converted
1793 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
1794 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1796 *) fix segv in mod_mime if no AddTypes are configured
1797 [John Sterling <sterling@covalent.net>]
1799 *) Enable ssl client authentication at SSL_accept time
1800 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1802 *) Fix a segfault in mod_include when the original request has no
1803 associated filename (e.g., we're filtering the error document for
1804 a bad URI). [Jeff Trawick]
1806 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
1808 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
1809 of httpd is started and shuts down due to socket conflict. Moving the
1810 call to ap_log_pid solves the problem.
1812 *) Changed the late-1.3 log_config substitution %c to %X, to log the
1813 status of the closed connection, as it conflicts with the far more
1814 common, historical ssl logging directive %...{var}c. [William Rowe]
1816 *) Added the common error/ tree to the build/install targets
1817 (similar to the common icons/ tree) for the multi-language error
1818 messages that Lars committed earlier. [William Rowe]
1820 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
1822 *) Added a default commented-out mod_ldap and mod_auth_ldap
1823 configuration to httpd-std.conf and httpd-win.conf
1826 *) Added documentation for mod_ldap and mod_auth_ldap.
1829 *) Enabled negative caching on attribute comparisons in the LDAP cache.
1830 Fixed a problem where the default cache TTL was set in milliseconds
1831 not microseconds causing the cache to time out almost immediately.
1834 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
1835 module code to follow APR. [Graham Leggett]
1837 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
1838 cleaned up when the connection pool pool is cleaned up.
1841 *) Fix a minor issue with Jeff Trawick's mod_include
1842 patch. Without this patch, the code will just allocate
1843 more bytes in get_combined_directive than are needed.
1846 *) Added the LDAP authentication module mod_auth_ldap.
1847 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1849 *) Added the LDAP cache and connection pooling module mod_ldap.
1850 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1852 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
1853 by allowing a module to disable itself if its prerequisites are not
1854 met. [Justin Erenkrantz]
1856 Changes with Apache 2.0.24
1858 *) Fix a couple of issues in mod_include when the tag appeared at
1859 offsets near 8192 in the file being parsed. [Jeff Trawick]
1861 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
1862 reached. [Jeff Trawick]
1864 *) Numerous improvements to the Win32 build system. Introduced command line
1865 builds without requiring .mak files for MSVC 6.0 and later versions.
1866 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
1869 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
1870 reporting of uninstalled services and other error conditions, and changed the
1871 default service name to Apache2. [William Rowe]
1873 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
1874 compatibility with existing Apache 1.3 Win32 Apache management utilites.
1875 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
1877 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
1878 [William Rowe, Greg Ames]
1880 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
1881 and RemoveCharset directives. [William Rowe]
1883 *) The Unix MPMs other than perchild now allow child server
1884 processes to use the accept mutex when starting as root and
1885 using SysV sems for the accept mutex. Previously, this
1886 combination would lead to fatal errors in the child server
1887 processes. perchild can't use SysV sems because of security
1888 issues. [Jeff Trawick, Greg Ames]
1890 *) Added Win32 revision stamp resources to all http binaries
1891 (including modules/ and support/ tools.) PR7322 [William Rowe]
1893 *) Fix ap_rvprintf to support more than 4K of data at one time.
1894 [Cody Sherr <csherr@covalent.net>]
1896 *) We have always used the obsolete/deprecated Netscape syntax
1897 for our tracking cookies; now the CookieStyle directive
1898 allows the Webmaster to choose the Netscape, RFC2109, or
1899 RFC2965 format. The new CookieDomain directive allows the
1900 setting of the cookie's Domain= attribute, too. PR #s 5006,
1901 5023, 5920, 6140 [Ken Coar]
1903 *) Tweak server/Makefile so that the rules for generating exports.c
1904 are compatible with make utilities which don't expand wildcards
1905 in a dependency list (e.g., OS/390 make, certain levels of GNU
1906 make). [Jeff Trawick]
1908 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
1910 *) Begin to sanitize the MPM configuration directives. Now, all
1911 MPMs use the same functions for all common MPM directives. This
1912 should make it easier to catch all bugs in these directives once.
1913 [Cody Sherr <csherr@covalent.net>]
1915 *) Close a major resource leak. Every time we had issued a
1916 graceful restart, we leaked a socket descriptor.
1919 *) Fix a problem with the new method code. We need to cast
1920 the 1 to an apr_int64_t or it will be treated as a 32-bit
1921 integer, and it will wrap after being shifted 32 times.
1922 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
1924 *) Fix a bug in mod_expires. Previous to this patch, if you
1925 told mod_expires to add 604800 seconds to the last-modified
1926 time, it actually added 604800 usec's to the last-modified time,
1927 so that when looking at the response it looked like nothing
1928 had been done. The root of the problem was that we always compute
1929 time in usec's, but we ask users to input sec's. This means we
1930 need to convert to usec's before using those values.
1933 *) The worker MPM now handles shutdown and restart requests. It
1934 definitely isn't perfect, but we do stop the servers correctly.
1935 The biggest problem right now is that SIGHUP causes the server to
1936 just die. [Ryan Bloom]
1938 Changes with Apache 2.0.23
1940 *) Use the prefork MPM by default on Unix. [various]
1942 *) Added a systray icon monitor application for Win32.
1943 [Mladen Turk <mturk@mappingsoft.com>]
1945 *) mod_rewrite: Fix the line ending on some non-Unix systems for
1946 messages written to the rewrite log.
1947 [Richard Labennett <rlabenn@us.ibm.com>]
1949 *) All mod_autoindex query parsing is now quietly quashed with the
1950 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
1951 still drops the column sort <a href>'s for the column headers, but
1952 IgnoreClient is required to ignore these Query options entirely.
1955 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
1956 to allow the client to select plain, FancyIndexing or HTMLTable
1957 formatting, V=[0|1] to inhibit or enable version sorting, and
1958 P=pattern to return only specific files. The old Query Arguments
1959 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
1960 as before), and O=A|D for ordering ascending or descending.
1963 *) Fixed an error in mod_include's directive parsing routines which
1964 caused #if, #elif, and #else expressions containing backslashes
1965 to be improperly evaluated. [Cliff Woolley]
1967 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
1968 drop the icon column, SuppressRules to drop the <hr> elements,
1969 and HTMLTable to create rudimentary HTML table listings (implies
1970 FancyIndexing). [William Rowe]
1972 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
1973 from Apache 1.3.15. This is needed for two reasons, first, given
1974 multiple machines within a server farm, ETags and Last-Modified
1975 stamps won't correspond from machine to machine, and second, many
1976 Unixes don't capture changes to the date or time stamp of existing
1977 files, since these don't modify the dirent itself. [William Rowe]
1979 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
1980 and DirectoryWidth options from Apache 1.3.10.
1981 [William Rowe, Ken Coar]
1983 *) Eliminated FancyIndexing directive, deprecated early in Apache
1984 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
1986 *) mod_autoindex now excludes any file names that would result in
1987 an error, other than a success or redirect. Also optimized
1988 the parent directory, always included except in the URI '/'.
1991 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
1992 negotiated index pages, and prevent the server from defaulting
1993 to an autoindex of the directory. mod_negotiation will now die
1994 with a 500 Internal Error if it could match some filenames
1995 (e.g. for mod_dir) but none can be served. mod_negotation now
1996 refuses to serve any file with an extention that mod_mime doesn't
1997 recognize, and wasn't part of the request. [William Rowe]
1999 *) Eliminate mod_cgi's handling of .exe files without the .exe file
2000 extension. This is already handled by multiviews, if the admin
2001 wishes to AddHandler .exe or define a content type handler and
2002 associate .exe files with that content type. Multiviews must be
2003 enabled to allow these to be served. [William Rowe]
2005 *) Speed up the server's response to a spike in incoming workload
2006 or restarts by assigning empty scoreboard slots to new processes
2007 when they are available. [Greg Ames]
2009 *) Add a handler to mod_includes.c. This handler is designed to
2010 implement the XbitHack directive. This can't be done with a
2011 fixup, because we need to check the content-type, which is
2012 only available in the handler phase. [Ryan Bloom]
2014 *) Make the includes filter check return codes from filters lower in
2015 the filter chain. If a lower level filter returns an error, then
2016 the request needs to stop immediately. This allows mod_include to
2017 stop parsing data once a lower filter recognizes an error.
2020 *) Add the ability to extend the methods that Apache understands
2021 and have those methods <limit>able in the httpd.conf. It uses
2022 the same bit mask/shifted offset as the original HTTP methods
2023 such as M_GET or M_POST, but expands the total bits from an int to
2024 an ap_int64_t to handle more bits for new request methods than
2025 an int provides. [Cody Sherr <csherr@covalent.net>]
2027 *) Fix broken mod_mime behavior in merging its arguments. Possible
2028 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
2030 *) Solve many mod_ssl porting issues (too many to detail) with
2031 help from the whole team, but most notably [Ralf S. Engelschall,
2032 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2033 Doug MacEachern, William Rowe, Cliff Woolley]
2035 *) More stall fixes for the threaded & worker mpm's.
2036 Make mod_status output more accurate. Don't
2037 count workers in processes which aren't actively
2038 serving requests. [Greg Ames]
2040 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
2042 *) Add a single listener/multiple worker MPM. This MPM is
2043 definately not fully correct, but it allows us to solve many
2044 of the problems that exist in the threaded MPM. This is a
2045 modified version of the threaded MPM. [Ryan Bloom]
2047 *) Improve content generation throughout Apache, providing closer
2048 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
2049 Transitional specifications. [William Rowe]
2051 Changes with Apache 2.0.22
2053 *) Fix a problem where the threaded MPM stalls after restarts or
2054 segfaults. Also prevent multiple active processes from using
2055 the same scoreboard slot. [Greg Ames]
2057 *) Apache/Win32 now fills in the service description with Apache's
2058 server version string, including loaded and advertised modules.
2061 *) Improved support for the Win32 build, to recover gracefully from
2062 missing apr or apr-util directories or the awk interpreter,
2063 create the proper cgi-bin examples, including a test-cgi.bat, and
2064 fix the perl shebang line for printenv.pl, when installing from
2065 the build environment. [William Rowe]
2067 *) Fix a segfault in threaded.c caused by passing uninitialized
2068 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
2070 *) Use new APR number conversion functions to reduce CPU consumption
2071 when setting the content length, and in mod_log_config.
2074 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
2075 where HEAD response headers were being repeated twice for
2076 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
2077 problem in the http_header filter was exposed by the recent rewrite
2078 of the content_length filter. [Taketo Kabe, Bill Stoddard]
2080 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
2081 restarts. A garbage pointer to a vhost's server_rec from the
2082 previous generation was being left around under certain
2083 conditions. [Greg Ames]
2085 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
2086 used to appear as '(none', without the closing paren.
2087 [Günter Knauf <eflash@gmx.net>]
2089 *) Improve the exports generating awk script. In the past, we had
2090 work around problems in the awk script by avoiding some #if and
2091 #ifdefs. This has bitten us many times in generating the exports.c
2092 file. This improvement allows corrects the header file parsing.
2093 [Sander Striker <striker@apache.org>]
2095 Changes with Apache 2.0.21
2097 *) Resolve the Win32 htpasswd bug, where a file that existed would be
2098 overwritten, regardless of the -c flag.
2099 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
2101 *) Introduce connection sub-pools into ab. Truncating the lifetime
2102 of these allocations means that ab no longer perpetually grows
2103 its working set, running out of memory on large request attempts.
2106 *) Make scoreboard creation a hook. This allows management
2107 modules to have access to the scoreboard at the time that it is
2108 created, and at every restart request.
2109 [Cody Sherr <csherr@covalent.net>]
2111 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
2112 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
2113 daemon index actually used in the scoreboard. I also
2114 updated the pertinent calls. [Paul J. Reder]
2116 *) Win32: Prevent listening sockets from being inherited by
2117 the Apache child process, CGI scripts, rotatelog process
2118 etc. If the Apache child process segfaults, any processes
2119 that the child started are not reaped. Prior to this fix,
2120 these processes inherited the listening sockets which sometimes
2121 prevented the restarted Apache child process from accepting
2122 connections (ie, the server would hang).
2125 *) Provide vhost and request strings when ExtendedStatus is on.
2128 *) Fix some issues with the pod and prefork: check the pod *after*
2129 processing a connection so that a server processing a time-
2130 consuming request bails out as soon as practical; when the
2131 parent process wakes up a server process via connect(), use an
2132 APR timeout on the connect() so that we don't hang for a long
2133 time if there aren't server processes around to do accept().
2134 [Jeff Trawick, Greg Ames]
2136 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
2137 spends a lot of time in apr_table_get calls. Using the default
2138 httpd.conf, the tables for languages and charsets are somewhat
2139 large, so the time spent scanning them on each request is
2140 significant. Replacing the tables with hash tables provides
2141 a nice speedup. [Brian Pane <bpane@pacbell.net>]
2143 *) Add two functions to allow modules to access random parts of the
2144 scoreboard. This allows modules compiled for one MPM to access the
2145 scoreboard, even if it the server was compiled for another MPM.
2146 [Harrie Hazewinkel <harrie@covalent.net>]
2148 Changes with Apache 2.0.20
2150 *) Fix problem in content-length filter where the filter would
2151 buffer all the output from a CGI before sending any bytes
2152 down the filter stack to the network. This problem would cause
2153 significant memory consumption if the CGIs generated
2154 lots of bytes. [Bill Stoddard]
2156 *) Get non-blocking CGI pipe reads working with the bucket brigades.
2159 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
2162 *) Fix a bug in the threaded MPM that would cause it to kill off all
2163 workers immediately after starting if the number of workers started
2164 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
2166 Changes with Apache 2.0.19
2168 *) Fix problem with threaded MPM. The problem was that if each child
2169 process was busy serving a single long-lived request and the server
2170 was sent a graceful restart signal, the server would stop serving
2171 requests. This would happen because each child process would wait to
2172 die until the last thread was done, and the parent wouldn't spawn any
2173 new children until a process died. Now, the parent looks at the fact
2174 that the children are dying gracefully, and starts new children.
2175 Those new children only start enough threads to compliment the number
2176 of threads in the other child process that shares the same spot in
2177 the scoreboard. In this way, we make sure to never go over
2178 MaxClients. [Ryan Bloom]
2180 *) modified mod_negotiation and mod_autoindex to speed up by almost a
2181 factor of two on apr_dir_read()-enhanced platforms, such as Win32
2182 and OS2, by calling ap_sub_request_lookup_dirent() with the results
2183 already provided by apr_dir_read(). [William Rowe]
2185 *) mod_file_cache is now more robust to filtering and serves requests
2186 slightly more efficiently. [Cliff Woolley]
2188 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
2189 Module was calling ap_rwrite() followed by ap_rflush() but the
2190 served content was not being displayed in the browser. Inspection
2191 of the output stream revealed that the first data chunk was
2192 missing the trailing CRLF required by the RFC. [Bill Stoddard]
2194 *) apxs no longer generates ap_send_http_header() in the example handler
2196 *) Fix an ab problem which could cause a divide-by-zero exception
2197 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
2198 [Ian Holsman <ianh@cnet.com>]
2200 *) Solve case-insensitive platforms' confusion about negotiated
2201 filenames, allowing files of differnt case to match in choosing
2202 the document to serve. [William Rowe]
2204 *) Fix brokenness when ThreadsPerChild is higher than the built-in
2205 limit. We left ap_threads_per_child at the higher value which
2206 led to segfaults when doing certain scoreboard operations.
2209 *) Fix seg faults and/or missing output from mod_include. The
2210 default_handler was using the subrequest pool for files and
2211 MMAPs, even though the associated APR structures typically
2212 live longer than the subrequest. [Greg Ames]
2214 *) Extend mod_setenvif to support specifying regular expressions
2215 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
2216 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
2217 will cause HAVE_TS to be set if any of the request headers begins
2218 with "TS" and has a value that begins with any character in the
2219 set [a-z]. [Bill Stoddard]
2221 *) httpd children now re-bind themselves to a random CPU on
2222 multiprocessor systems on AIX via bindprocessor() in 2.0.
2223 [Victor J. Orlikowski]
2225 *) Fix htdigest. It would go into a loop in getline when adding
2226 a second user. [Bill Stoddard]
2228 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
2230 *) Automatically generate httpd.exp for AIX.
2231 DSOs now work again on AIX in 2.0
2232 [Victor J. Orlikowski]
2234 *) Add a new request hook, error_log. This phase allows modules
2235 to act on the error log string _after_ it has been written
2236 to the error log. The goal for this hook is to allow monitoring
2237 modules to send the error string to the monitoring agent.
2240 *) Modify mod_echo to make it use filters for input and output.
2241 [Ryan Morgan <rmorgan@covalent.net>]
2243 *) Extend mod_headers to support conditional driven Header
2244 add, append and set. Use SetEnvIf to set an envar and conditionally
2245 add/append/set headers based on this envar thusly:
2247 SetEnvIf TSMyHeader value HAVE_TSMyHeader
2248 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
2250 If the request contains header "TSMyHeader: value" then header
2251 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
2254 *) Extend mod_headers to support using format specifiers on Header
2255 add, append and set header values. Two format specifiers are supported:
2257 %t - reports, in UTC microseconds since the epoch, when the
2258 request was received.
2260 %D - reports the time, in microseconds, between when the request was
2261 received and the response sent.
2264 Header add MyHeader "This request served in %D microseconds. %t"
2266 results in a header being added to the response that looks like this:
2268 MyHeader: This request served in D=5438 microseconds. t=991424704447256
2272 *) Fix reset_filter(). We need to be careful how we remove filters.
2273 If we set r->output_filters to NULL, we also have to reset the
2274 connection's filters. [John Sterling]
2276 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
2278 *) Add a check to ap_die() to make sure the filter stack is sane and
2279 contains the correct basic filters when an error occurs. This fixes
2280 a problem where headers are not being sent on error. [John Sterling]
2282 *) New Header directive 'echo' option. "Header echo regex" will
2283 cause any headers received on the request that match regex to be
2284 echoed to (included in) the response headers.
2287 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
2288 This prevented the inclusion of apr_compat.h. PR #7773
2289 [Oleg Broytmann <phd@phd.pp.ru>]
2291 *) Moved util_uri to the apr-util library. This required a bunch of
2292 apr_name changes for the uri utility functions. [Justin Erenkrantz]
2294 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
2295 insert_filter phase so that other filters are not bypassed by default.
2298 *) Reimplement mod_headers as an output filter. mod_headers can now
2299 add custom headers to inbound requests using the RequestHeader directive
2300 and to responses using the same old Header directive. [Graham Leggett]
2302 Changes with Apache 2.0.18
2304 *) Fix command-line processing so that if a bad argument is specified
2305 Apache will exit. [Jeff Trawick]
2307 *) Change the make targets and rules to be consistent in all of the
2308 Apache-owned source trees. [Roy Fielding]
2310 *) Fix processing of the TRACE method. Previously we passed bogus
2311 parms to form_header_field() and it overlaid some vhost structures,
2312 resulting in a segfault in check_hostalias().
2313 [Greg Ames, Jeff Trawick]
2315 *) Win32: Add support for reliable piped logs. If the logging process
2316 goes down, Apache will automatically restart it. This function has
2317 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
2320 *) Do not start piped log processes during the config file
2321 preflight. This change also circumvents a problem on
2322 Windows where the rotatelog processes created during preflight
2323 was not getting cleaned up properly.
2326 *) add "Request Phase Participation" info to mod_info
2329 *) Make first phase changes to the scoreboard data structures in
2330 preparation for the rewriting of the scoreboard per my posted
2331 design notes. [Paul J. Reder]
2333 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
2334 and apr-util, allow it to be overridden by the configure command-line
2335 (default="--silent") and introduce LT_LDFLAGS to replace what we were
2336 formerly abusing as LTFLAGS. [Roy Fielding]
2338 *) Clean up the reporting of incorrect closing container tags.
2339 [Barrie Slaymaker <barries@slaysys.com>]
2341 *) Simplify the configure process by moving all libtool stuff to APR
2342 and moving hints.m4 inline. [Roy Fielding]
2344 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
2345 of functions used by mod_proxy for export in the DLL
2346 [Ian Holsman <IanH@cnet.com>]
2348 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
2349 request body from its stdin but no reqest body is being written to
2350 the cgi. [Jeff Trawick]
2352 *) mod_log_config: %c connection status incorrectly logged
2353 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
2356 *) Get mod_cern_meta working under Windows
2359 *) Create Files, and thus MMAPs, out of the request pool, not the
2360 connection pool. This solves a small resource leak that had us
2361 not closing files until a connection was closed. In order to do
2362 this, at the end of the core_output_filter, we loop through the
2363 brigade and convert any data we have into a single HEAP bucket
2364 that we know will survive clearing the request_rec.
2365 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
2368 *) Completely revamp configure so that it preserves the standard make
2369 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
2370 the configure additions to EXTRA_* variables. Also, allow the user
2371 to specify NOTEST_* values for all of the above, which eliminates the
2372 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
2373 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
2374 avoid pointless duplications. Fix the order in which flags are given
2375 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
2376 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
2377 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
2378 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
2380 *) Get mod_tls to compile/work better on Windows. PR #7612
2381 [Bernhard Schrenk <b.schrenk@improx.com>]
2383 *) Fix shutdown/restart hangs in the threaded MPM.
2384 [Jeff Trawick, Greg Ames, Ryan Bloom]
2386 *) Removed the keptalive boolean from conn_rec because it is now only
2387 used by a single routine and can be replaced by a local variable.
2388 [Greg Stein, Ryan Bloom, Roy Fielding]
2390 *) Patch prefork to put enough of the signal processing back in so that
2391 signals are all handled properly now. The previous patch fixed the
2392 deadlock race condition, but broke the user directed signal handling.
2393 This fixes it to work the way it did before my previous prefork patch
2394 (primarily, SIGTERM is now working).
2396 *) Change how input filters decide how much data is returned to the
2397 higher filter. We used to use a field in the conn_rec, with this
2398 change, we use an argument to ap_get_brigade to determine how much
2399 data is retrieved. [Ryan Bloom]
2401 *) Fix seg fault at start-up introduced by Ryan's change to enable
2402 modules to specify their own logging tags. mod_log_config
2403 registers an optional function, ap_register_log_handler().
2404 ap_register_log_handler() was being called by http_core before
2405 the directive hash table was created. This patch creates the
2406 directive hash table before ap_register_log_handler() is
2407 registered as an optional function.
2408 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2410 *) Add ap_set_int_slot() function
2411 [John K. Sterling <sterling@covalent.net>]
2413 *) Under certain circumstances, Apache did not supply the
2414 right response headers when requiring authentication.
2415 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
2416 (This is a port of the change that went into Apache 1.3.19.)
2418 *) Allow modules to specify their own logging tags. This basically
2419 allows a module to tell mod_log_config that when %x is encountered
2420 a specific function should be called. Currently, x can be any single
2421 character. It may be more useful to make this a string at some point.
2424 Changes with Apache 2.0.17
2426 *) If a higher-level filter handles the the byterange aspects of a
2427 request, then the byterange filter should not try to redo the
2428 work. The most common case of this happening, is a byterange
2429 request going through the proxy, and the origin server handles
2430 the byterange request. The proxy should ignore it.
2431 [Graham Leggett <minfrin@sharp.fm>]
2433 *) Changed the threaded mpm to have child_main join to each of the
2434 worker threads to make sure the kids are all gone before child_main
2435 exits after a signal (cleanup from perform_idle_server_maintenance).
2436 This is an extension of Ryans recent commit to make the child_main
2439 *) Add more options to the ap_mpm_query function. This also allows MPMs to
2440 report if their threads are dynamic or static. Finally, this also
2441 implements a new API, ap_show_mpm, which returns the MPM that was
2442 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
2444 *) Do not install the binaries from the support directory twice.
2445 [jun-ichiro hagino <itojun@iijlab.net>]
2447 *) The ap_f* functions should flush data to the filter that is passed
2448 in, not the the filter after the one passed in.
2449 [Ryan Morgan <rmorgan@covalent.net>]
2451 *) Make ab work again by changing its native types to apr types and formats.
2452 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2454 *) Move the byterange filter and all of the supporting functions back
2455 to the HTTP module. The byterange filter turned out to be very
2456 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
2458 *) Make clean, distclean, and extraclean consistently according to the
2459 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2461 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
2462 This may have been causing problems stopping processes in the threaded
2465 *) Fix content-length in mod_negotiation to a long int representation.
2468 *) Remove BindAddress from the default config file.
2469 [giles@nemeton.com.au]
2471 *) Allow module authors to add a module to their Apache build using
2472 --with-module, without re-running buildconf. The syntax is:
2473 --with-module=module_type:/path/to/module.c
2474 The configure script will copy the module.c file to
2475 modules/module_type, and it will be added to the relevant Makefiles.
2476 currently, this only works for static modules. [Ryan Bloom]
2478 *) Changes required to make prefork clean up idle children properly.
2479 There was a window during which a starting worker deadlocks when
2480 an idle cleanup arrives before it completes init. Apache then keeps
2481 trying to cleanup the same deadlocked worker forever (until higher
2482 pids come along, but it still will never reduce below the deadlocked
2483 pid). Thus the number of children would not reduce to the correct
2484 idle level. [Paul J. Reder]
2486 Changes with Apache 2.0.16
2488 *) Change the default installation directory to /usr/local/apache2,
2489 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
2491 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
2494 *) Get MaxRequestsPerChild working with the Windows MPM.
2497 *) Make generic hooks to work, with mod_generic_hook_import/export
2498 experimental modules. [Ben Laurie, Will Rowe]
2500 *) Fix segfaults for configuration file syntax errors such as
2501 "<Directory>" followed by "</Directory" and
2502 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
2504 *) Cleanup the --enable-layout option of configure. This makes
2505 us use a consistent location for the config.layout file, and it
2506 makes configure more portable.
2507 [jun-ichiro hagino <itojun@iijlab.net>]
2509 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
2510 csv/gnuplot format, rudimentary ssl support and various other tweaks
2511 to make results more true to what is measured. The upshot of this it
2512 turns out that 'ab' has often underreported the true performance of
2513 apache. Often by a order of magnitude :-) See talk/paper of Sander
2514 Temme at April ApacheCon 2001 for details.
2515 [Dirk-Willem van Gulik]
2517 *) Clean up mod_cgid's temporary request pool. Besides fixing a
2518 storage leak this ensures that some unnecessary pipes are closed.
2521 *) Performance: Add quick_handler hook. This hook is called at the
2522 very beginning of the request processing before location_walk,
2523 translate_name, etc. This hook is useful for URI keyed content
2524 caches like Mike Abbott's Quick Shortcut Cache.
2527 *) top_module global variable renamed to ap_top_module [Perl]
2529 *) Move ap_set_last_modified to the core. This is a potentially
2530 controversial change, because this is kind of HTTP specific. However
2531 many protocols should be able to take advantage of this kind of
2532 information. I expect that headers will need one more layer of
2533 indirection for multi-protocol work, but this is a small step in
2534 the right direction. [Ryan Bloom]
2536 *) Enable mod_status by default. This matches what Apache 1.3 does.
2539 *) Add a ScriptSock directive to the default config file. This is
2540 only enabled when mod_cgid is used.
2541 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2543 Changes with Apache 2.0.15
2545 *) Untangled the buildconf script and eliminated the need for build's
2546 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
2547 libtool muck that is now under srclib/apr/build. [Roy Fielding]
2549 *) Win32: Don't accept more connections than we have worker threads
2553 *) Fix bug in the Unix threaded.c MPM that allowed child processes
2554 to fork() new child processes.
2557 *) Fix a major security problem with double-reverse lookup checking.
2558 Previously, a client connecting over IPv4 would not be matched
2559 properly when the server had an IPv6 listening socket. PR #7407
2560 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
2562 *) Change the way the beos MPM handles polling to allow it to stop and
2563 restart. Problem was the sockets being polled were being reset by
2564 the select call, so once it had accepted a connection it was no
2565 longer listening on the UDP socket we use for shutdown instructions.
2566 APR needs to be altered, patch on it's way. [David Reid]
2568 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
2569 on error exit from ap_getline(). Some other code got upset because
2570 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
2572 *) Handle ap_discard_request_body() being called more than once.
2573 [Greg Ames, Jeff Trawick]
2575 *) Get rid of an inadvertent close of file descriptor 2 in
2576 mod_mime_magic. [Greg Ames, Jeff Trawick]
2578 *) Add a hook, create_request. This hook allows modules to modify
2579 a request while it is being created. This hook is called for all
2580 request_rec's, main request, sub request, and internal redirect.
2581 When this hook is called, the the r->main, r->prev, r->next
2582 pointers have been set, so modules can determine what kind of
2583 request this is. [Ryan Bloom]
2585 *) Cleanup the build process a bit more. The Apache configure
2586 script no longer creates its own helper scripts, it just
2588 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2590 *) Stop the forced downgrade of the connection to HTTP/1.0 for
2591 proxy requests. [Graham Leggett]
2593 *) Avoid using sscanf to determine the HTTP protocol number in
2594 the common case because sscanf is a performance hog. From
2595 Mike Abbot's Accelerating Apache patch number 6.
2596 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
2598 *) Fix a security exposure in mod_access. Previously when IPv6
2599 listening sockets were used, allow/deny-from-IPv4-address rules
2600 were not evaluated properly (PR #7407). Also, add the ability to
2601 specify IPv6 address strings with optional prefix length on Allow
2602 and Deny. [Jeff Trawick]
2604 *) Enhance rotatelogs so that a UTC offset can be specified, and
2605 the logfile name can be formatted using strftime(3). (Brought
2606 forward from 1.3.) [Ken Coar]
2608 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
2609 DuplicateHandle on an IOCompletionPort (a practice which
2610 MS "discourages"). The new model does not rely on associating
2611 the completion port with the listening sockets, thus the
2612 completion port can be completely managed within the child
2613 process. A dedicated thread accepts connections off the network,
2614 then calls PostQueuedCompletionStatus() to wake up worker
2615 threads blocked on the completion port.
2618 *) Bring forward the --suexec-umask option which allows the
2619 builder to preset the umask for suexec processes. [Ken Coar]
2621 *) Add a -V flag to suexec, which causes it to display the
2622 compile-time settings with which it was built. (Only
2623 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
2625 *) Mod_include should always unset the content-length if the file is
2626 going to be passed through send_parsed_content. There is no to
2627 determine if the content will change before actually scanning the
2628 entire content. It is far safer to just remove the C-L as long
2629 as we are scanning it. [Ryan Bloom]
2631 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
2632 request and not Proxy-Authenticate.
2633 [Graham Leggett <minfrin@sharp.fm>]
2635 Changes with Apache 2.0.14
2637 *) Fix content-length computation. We ONLY compute a content-length if
2638 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
2639 or we already have all the data. [Ryan Bloom]
2641 *) Report unbounded containers in the config file. Previously, a typo
2642 in the </container> directive could result in the rest of the config
2643 file being silently ignored, with undesired defaults used.
2646 *) Make the old_write filter use the ap_f* functions for the buffering.
2649 *) Move more code from the http module into the core server. This
2650 is core code, basically the default handler, the default input
2651 and output filters, and all of the core configuration directives.
2652 All of this code is required in order for the server to work, with or
2653 without HTTP. The server is closer to working without the HTTP
2654 module, although there is still more to do. [Ryan Bloom]
2656 *) Fix a number of SGI compile warnings throughout the server. Fix some
2657 bad parameters to apr_bucket_read(). Fix a bad statement in
2658 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
2659 consistently; we were mixing apr_time_t and time_t in invalid ways
2660 before. In load_file(), call apr_dso_error() instead of
2661 apr_strerror() so that we get a more specific string on some platforms.
2662 PR #6980 [Jeff Trawick]
2664 *) Allow modules to query the MPM about it's execution profile. This
2665 query API can and should be extended in the future, but for now,
2666 max_daemons, and threading or forking is a very good start.
2667 [Jon Travis <jtravis@covalent.net>]
2669 *) Modify mod_include to send blocks of data no larger than 9k.
2670 Without this, mod_include will wait until the whole file is parsed,
2671 or the first tag is found to send any data to the client.
2672 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2674 *) Fix mod_info, so that <Directory> and <Location> directives are
2675 not displayed twice when displaying the current configuration.
2676 [Ryan Morgan <rmorgan@covalent.net>]
2678 *) Add config directives to override DEFAULT_ERROR_MSG and
2679 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
2680 [Dan Rench <drench@xnet.com>]
2682 *) Get mod_info building and loading on Win32. [William Rowe]
2684 *) Begin to move protocol independant functions out of mod_http. The goal
2685 is to have only functions that are HTTP specific in the http directory.
2688 Changes with Apache 2.0.13
2690 *) Don't assume that there will always be multiple calls to the byterange
2691 filter. It is possible that we will need to do byteranges with only
2692 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
2694 *) Move the error_bucket definition from the http module to the
2695 core server. Every protocol will need this ability, not just
2698 Changes with Apache 2.0.12
2700 *) Modify mod_file_cache to save pre-formatted strings for
2701 content-length and last-modified headers for performance.
2702 [Mike Abbot <mja@trudge.engr.sgi.com>]
2704 *) Namespace protect IOBUFSIZ since it is exposed in the API.
2705 [Jon Travis <jtravis@covalent.net>]
2707 *) Use "Basic" authentication instead of "basic" in ab, as the spec
2708 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
2710 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
2711 without ever filling it out. This fixes PR 7271.
2712 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
2713 Cliff Woolley <cliffwoolley@yahoo.com>]
2715 *) Add a couple of GCC attribute tags to printf style functions.
2716 [Jon Travis <jtravis@covalent.net>]
2718 *) Add the correct language tag for interoperation with the Taiwanese
2719 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
2721 *) Migrate the perchild MPM to use the new apr signal child, and
2722 APR thread functions. [Ryan Bloom]
2724 *) Close one copy of the CGI's stdout before creating the new process.
2725 The CGI will still have stdout, because we have already dup'ed it.
2726 This keeps Apache from waiting forever to send the results of a CGI
2727 process that has forked a long-lived child process.
2728 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2730 *) Remove the rest of the pthreads functions from the threaded MPM.
2731 This requires the APR support for a signal thread that was just
2734 *) Make mod_dir use a fixup for sending a redirect to the browser.
2735 Before this, we were using a handler, which doesn't make much
2736 sense, because the handler wasn't generating any data, it would
2737 either return a redirect error code, or DECLINED. This fits the
2738 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
2740 *) Make the threaded MPM use APR threads instead of pthreads.
2743 *) Get mod_tls to the point where it actually appears to work in all cases.
2746 *) implement --enable-modules and --enable-mods-shared for "all" and
2747 "most". [Greg Stein]
2749 *) Move the threaded MPM to use APR locks instead of pthread locks.
2752 *) Rename mpmt_pthread to threaded. This is more in line with the
2753 fact that mpmt_pthread shouldn't be using pthreads directly, and
2754 it is a smaller name that doesn't tie into anything.
2757 *) Rename the module structures so that the exported symbol matches
2758 the file name, and it is easier to automate the installation
2759 process (generating LoadModule directives from the module filenames).
2762 *) Remove the coalesce filter. With the ap_f* functions, this filter
2763 is no longer needed. [Ryan Bloom]
2765 Changes with Apache 2.0.11
2767 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
2768 added feature of allowing a uid/gid per child process. If no
2769 uid/gid is specified, then Perchild behaves exactly like dexter.
2772 *) Get perchild building again. [Ryan Bloom]
2774 *) Don't disable threads just because we are using the prefork MPM.
2775 If somebody wants to compile without threads, they must now add
2776 --disable-threads to the configure command line. [Ryan Bloom]
2778 *) Begin to move the calls to update_child_status into common code, so
2779 that each individual MPM does not need to update the scoreboard itself.
2782 *) Allow mod_tls to compile under Unix boxes where openssl has been
2783 installed to the system include files.
2784 [Gomez Henri <new-httpd@slib.fr>]
2786 *) Cleanup the mod_tls configure process. This should remove any need
2787 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
2788 configure doesn't check that yet. [Ryan Bloom]
2790 *) Add a very early prototype of SSL support (in mod_tls.c). It is
2791 vital that you read modules/tls/README before attempting to build
2794 *) Fix a potential seg fault on all platforms. David Reid fixed this
2795 on BEOS, but the problem could happen anywhere, so we don't want
2796 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
2798 *) Add new LogFormat directive, %D, to log time it takes to serve a
2799 request in microseconds. [Bill Stoddard]
2801 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
2802 SetOutputFilter. This corresponds nicely with the other Set
2803 directives, which operate on containers while the Add* directives
2804 tend to work directly on extensions. [Ryan Bloom]
2806 *) Cleanup the header handling a bit. This uses the apr_brigade_*
2807 functions for the buffering so that we don't need to compute
2808 the length of the headers before we actually create the header
2809 buffer. [Ryan Bloom]
2811 *) Allow filters to buffer data using the ap_f* functions. These have
2812 become macros that resolve directly to apr_brigade_*.
2815 *) Get the Unix MPM's to do a graceful restart again. If we are going
2816 to register a cleanup with ap_cleanup_scoreboard, then we have to
2817 kill the cleanup with the same function, and that function can't be
2818 static. [Ryan Bloom]
2820 *) Install all required header files. Without these, it was not
2821 possible to compile some modules outside of the server.
2824 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
2825 forward from 1.3 to 2.0, we missed a single line, which broke regex
2826 aliases. [Ryan Bloom]
2828 *) We have a poor abstraction in the protocol. This is a temporary
2829 hack to fix the bug, but it will need to be fixed for real. If
2830 we find an error while sending out a custom error response, we back
2831 up to the first non-OK request and send the data. Then, when we send
2832 the EOS from finalize_request_protocol, we go to the last request,
2833 to ensure that we aren't sending an EOS to a request that has already
2834 received one. Because the data is sent on a different request than
2835 the EOS, the error text never gets sent down the filter stack. This
2836 fixes the problem by finding the last request, and sending the data
2837 with that request. [Ryan Bloom]
2839 *) Make the server status page show the correct restart time, and
2840 thus the proper uptime. [Ryan Bloom]
2842 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
2843 should reduce the amount of duplicate code that is required to
2844 create CGI processes.
2845 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2847 *) ap_new_connection() closes the socket and returns NULL if a socket
2848 call fails. Usually this is due to a connection which has been
2849 reset. [Jeff Trawick]
2851 *) Move the Apache version information out of httpd.h and into release.h.
2852 This is in preparation for the first tag with the new tag and release
2853 system. [Ryan Bloom]
2855 *) Begin restructuring scoreboard code to enable adding back in
2856 the ability to use IPC other than shared memory.
2857 Get mod_status working on Windows again. [Bill Stoddard]
2859 *) Make mod_status work with 2.0. This will work for prefork,
2860 mpmt_pthread, and dexter. [Ryan Bloom]
2862 *) Correct a typo in httpd.conf.
2863 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
2865 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
2867 *) Get the correct IP address if ServerName isn't set and we can't
2868 find a fully-qualified domain name at startup.
2869 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
2871 *) Make mod_cgid work with SuExec. [Ryan Bloom]
2873 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
2874 'extra' stat's for user/group since they should never occur, and now
2875 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
2876 volumes. [William Rowe]
2878 *) Adopt apr features to simplify mod_includes. This changes the
2879 behavior of the USER_NAME variable, unknown uid's are now reported
2880 as USER_NAME="<unknown>" rather than the old user#000 result.
2881 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
2883 *) Adopt apr features for simplifing mod_userdir, and accept the new
2884 Win32/OS2 exceptions without hiccuping. [William Rowe]
2886 *) Replace configure --with-optim option by using and saving the
2887 environment variable OPTIM instead. This is needed because configure
2888 options do not support multiple flags separated by spaces.
2891 *) Fix some byterange handling. If we get a byte range that looks like
2892 "-999999" where that is past the end of the file, we should return
2893 a PARTIAL CONTENT status code, and return the whole file as one big
2894 byterange. This matches the 1.3 handling now. [Ryan Bloom]
2896 *) Make the error bucket a real meta-data bucket. This means that the
2897 bucket length is 0, and a read returns NULL data. If one of these
2898 buckets is passed down after the headers are sent, this data will
2899 just be ignored. [Greg Stein]
2901 *) The prefork MPM wasn't killing child processes correctly if a restart
2902 signal was received while the process was serving a request. The child
2903 process would become the equivalent of a second parent process. If
2904 we break out of the accept loop, then we need to do die after cleaning
2905 up after ourselves. [Ryan Bloom]
2907 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
2908 restarts. [Ryan Bloom]
2910 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
2911 the most optimal APR_FINFO_wanted bits. This spares Win32 from
2912 performing very expensive owner, group and permission lookups
2913 and allows the server to function until these apr_finfo_t fields
2914 are implemented under Win32. [William Rowe]
2916 *) Support for typedsafe optional functions - that is functions exported by
2917 optional modules, which, therefore, may or may not be present, depending
2918 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
2919 for sample code. [Ben Laurie]
2921 *) filters can now report an HTTP error to the server. This is done
2922 by sending a brigade where the first bucket is an error_bucket.
2923 This bucket is a simple bucket that stores an HTTP error and
2924 a string. Currently the string is not used, but it may be needed
2925 to output an error log. The http_header_filter will find this
2926 bucket, and output the error text, and then return
2927 AP_FILTER_ERROR, which informs the server that the error web page
2928 has already been sent. [Ryan Bloom]
2930 *) If we get an error, then we should remove all filters except for
2931 those critical to serving a web page. This fixes a bug, where
2932 error pages were going through the byterange filter, even though
2933 that made no sense. [Ryan Bloom]
2935 *) Relax the syntax checking of Host: headers in order to support
2936 iDNS. PR#6635 [Tony Finch]
2938 *) Cleanup the byterange filter to use the apr_brigade_partition
2939 and apr_bucket_copy functions. This removes a lot of very messy
2940 code, and hopefully makes this filter more stable.
2943 *) Remove AddModule and ClearModuleList directives. Both of these
2944 directives were used to ensure that modules could be enabled
2945 in the correct order. That requirement is now gone, because
2946 we use hooks to ensure that modules are in the correct order.
2949 *) When SuExec is specified, we need to add it to the list of
2950 targets to be built. If we don't, then any changes to the
2951 configuration won't affect SuExec, unless 'make suexec' is
2952 specifically run. [Ryan Bloom]
2954 *) Cleaned out open_file from mod_file_cache, as apr now accepts
2955 the APR_XTHREAD argument to open a file for consumption by
2956 parallel threads on win32. [William Rowe]
2958 *) Correct a bug in determining when we follow symlinks. The code
2959 expected a stat -1 result, not an apr_status_t positive error.
2960 Also check if the APR_FINFO_USER fields are valid before we
2961 follow the link. [William Rowe]
2963 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
2964 mpm_common.c. These functions are only valid on some platforms,
2965 so they should not be in the main-line code. [Ryan Bloom]
2967 *) Remove ap_chdir_file(). This function is not thread-safe,
2968 and nobody is currently using it. [Ryan Bloom]
2970 *) Do not try to run make depend if there are no .c files in the
2971 current directory, doing so makes `make depend` fail.
2974 *) Update highperformance.conf to work with either prefork or
2975 pthreads mpms. [Greg Ames]
2977 *) Stop checking to see if this is a pipelined request if we know
2978 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
2979 This keeps us from making an extra read call when serving a 1.0
2980 request. [Ryan Bloom and Greg Stein]
2982 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
2983 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
2984 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
2986 *) Fix the RFC number mentioned when complaining about a missing
2987 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
2989 *) Fix an endless loop in ab which occurred when ab was posting
2990 and the server dropped the connection unexpectedly.
2993 *) Fix a segfault while handling request bodies in ap_http_filter().
2994 This problem has been seen with mod_dav usage as well as with
2995 requests where the body was just being discarded. [Jeff Trawick]
2997 *) Some adjustment on the handling and automatic setting (via
2998 hints.m4) of various compilation flags (eg: CFLAGS). Also,
2999 add the capability to specify flags (NOTEST_CFLAGS and
3000 NOTEST_LDFLAGS) which are used to compile Apache, but
3001 not used during the configuration process. Useful for
3002 flags like "-Werror". [Jim Jagielski]
3004 *) Stop using environment variables to force debug mode or
3005 no detach. We now use the -D command line argument to
3006 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
3007 [Greg Stein, Ryan Bloom]
3009 *) Change handlers to use hooks. [Ben Laurie]
3011 *) Stop returning copies of filenames from both apr_file_t and
3012 apr_dir_t. We pstrdup the filenames that we store in the
3013 actual structures, so we don't need to pstrdup the strings again.
3016 *) mod_cgi: Fix some problems where the wrong error value was being
3017 traced. [Jeff Trawick]
3019 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
3022 *) Add generic hooks. [Ben Laurie]
3024 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
3026 *) Fix a segfault caused by mod_ext_filter when the external filter
3027 program does not exist. [Jeff Trawick]
3029 *) Fix an output truncation error when on an HTTP >= 1.0 request an
3030 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
3031 was served through mod_charset_lite (or anything else that would
3032 create a transient bucket in this size range). ap_bucket_make_heap()
3033 silently failed (fixed), transient_setaside() discovered it, but
3034 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
3036 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
3037 is that some browsers send extra lines at the end of POST requests, and
3038 we don't want to delay sending data back to the user just because the
3039 browser isn't well behaved. [Ryan Bloom]
3041 *) Get SuEXEC working again. We can't send absolute paths to suExec
3042 because it refuses to execute those programs. SuEXEC also wasn't
3043 always recognizing configuration changes made using the autoconf
3046 *) Allow the buildconf process to find the config.m4 files in the correct
3047 order. Basically, we can now name config.m4 files as config\d\d.m4,
3048 and we will sort them correctly when inserting them into the build
3049 process. [Ryan Bloom]
3051 *) Get mod_cgid to use apr calls for creating the actual CGI process.
3052 This also allows mod_cgid to use ap_os_create_priviledged_process,
3053 thus allowing for SuExec execution from mod_cgid. Currently, we do
3054 not support everything that standard SuExec supports, but at least
3055 it works minimally now. [Ryan Bloom]
3057 *) Allow SuExec to be configured from the ./configure command line.
3060 *) Update some of the docs in README and INSTALL to reflect some of
3061 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
3063 *) If we get EAGAIN returned from the call to apr_sendfile, then we
3064 need to call sendfile again. This gets us serving large files
3065 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
3067 *) Get the support programs building cleanly again.
3068 [Cliff Woolley <cliffwoolley@yahoo.com>]
3070 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
3071 current directory logic now backs up over bin/ to determine the
3072 server root from the Apache.exe path.
3074 *) Apache/Win32 now follows the standard conventions of mod_foo.so
3075 loadable modules, dynamic libs are all named libfoo.dll, and the
3076 makefile.win populates the include, lib and libexec directories.
3078 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
3079 Apache gets IPv6 listening sockets by default. Additionally, the
3080 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
3081 numeric address strings (e.g., "Listen [fe80::1]:8080").
3084 *) Modify the install directory layout. Modules are now installed in
3085 modules/. Shared libraries should be installed in libraries/, but
3086 we don't have any of those on Unix yet. All install directories
3087 are modifyable at configure time. [Ryan Bloom]
3089 *) Install all header files in the same directory on Unix. [Ryan Bloom]
3091 *) Get the functions in server/linked into the server, regardless of
3092 which modules linked into the server. This uses the same hack
3093 for Apache that we use for APR and apr-util to ensure all of the
3094 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
3095 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
3096 the scripts a bit easier.
3099 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
3100 on the query, and remove IPv4 dependencies. [Jeff Trawick]
3102 *) Get all of the auth modules to the point that they will install and
3103 be loadable into the server. Our new build/install mechanism expects
3104 that all modules will have a common name format. The auth modules
3105 didn't use that format, so we didn't install them properly.
3108 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
3109 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
3111 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
3113 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
3114 after the end of the response. [Ryan Bloom]
3116 *) Get byterange requests working with responses that do not have a
3117 content-length. Because of the way byterange requests work, we have to
3118 have all of the data before we can actually do the byterange, so we
3119 can compute the content-length in the byterange filter.
3122 *) Get exe CGI's working again on Windows.
3125 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
3126 they keep track of whether or not their post config hook has been
3127 called before. Instead of a static variable (which is replaced when
3128 the DSO is loaded a second time), use userdata in the process pool.
3131 Changes with Apache 2.0a9
3133 *) Win32 now requires perl to complete the final install step for users
3134 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
3135 and installs the conf, htdocs and htdocs/manual directories.
3138 *) Make mod_include use a hash table to associate directive tags with
3139 functions. This allows modules to implement their own SSI tags easily.
3140 The idea is simple enough, a module can insert it's own tag and function
3141 combination into a hash table provided by mod_include. While mod_include
3142 parses an SSI file, when it encounters a tag in the file, it does a
3143 hash lookup to find the function that implements that tag, and passes
3144 all of the relevant data to the function. That function is then
3145 responsible for processing the tag and handing the remaining data back
3146 to mod_include for further processing.
3147 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3149 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
3150 fewer parameters: the local and remote socket addresses were removed
3151 from the parameter list because all required information is available
3152 via the APR socket. [Jeff Trawick]
3154 *) Distribution directory structure reorganized to reflect a
3155 normal source distribution with external install targets.
3158 *) The MPMs that need multiple segments of shared memory now create
3159 two apr_shmem_t variables, one for each shared memory allocation.
3160 the problem is that we can't determine how much memory will be required
3161 for shared memory allocations once we try to allocate more than one
3162 variable. The MM code automatically aligns the shared memory allocations,
3163 so we end up needing to pad the amount of shared memory we want based
3164 on how many variables will be allocated out of the shared memory segment.
3165 It is just easier to create a second apr_shmem_t variable, and two
3166 shmem memory blocks.
3169 *) Cleanup the export list a bit. This creates a single unified list of
3170 functions exported by APR. The export list is generated at configure
3171 time, and that list is then used to generate the exports.c file.
3172 Because of the way the export list is generated, we only export those
3173 functions that are valid on the platform we are building on.
3176 *) Enable logging the cookie with mod_log_config
3177 [Sander van Zoest <sander@covalent.net>]
3179 *) Fix a segfault in mod_info when it reaches the end of the configuration.
3182 *) Added lib/aputil/ as a placeholder for utility functions which are not
3183 specific to the Apache HTTP Server (but do not make sense with APR).
3184 The first utility is "apu_dbm": a set of functions to work with DBM
3185 files. This first version can be compiled for SDBM or GDBM databases.
3188 *) Complete re-write of mod_include. This makes mod_include a filter that
3189 uses buckets directly. This has now served the FAQ correctly.
3190 [Paul Reder <rederpj@raleigh.ibm.com>]
3192 *) Allow modules to specify the first filter in a sub_request when
3193 making the sub_request. This keeps modules from having to change the
3194 output_filter immediately after creating the sub-request, and therefore
3195 skip the sub_req_output_filter. [Ryan Bloom]
3197 *) Update ab to accept URLs with IPv6 literal address strings (in the
3198 format described in RFC 2732), and to build Host header fields in
3199 the same format. This allows IPv6 literal address strings to be
3200 used with ab. This support has been tested against Apache 1.3 with
3201 the KAME patch, but Apache 2.0 does not yet work with this format
3202 of the Host header field. [Jeff Trawick]
3204 *) Accomodate an out-of-space condition in the piped logs and the
3205 rotatelogs.c code, and no longer churn log processes for this
3206 condition. [Victor J. Orlikowski]
3208 *) Add support for partial writes with apr_sendfile() to core_output_filter.
3211 Changes with Apache 2.0a8
3213 *) Add a directive to mod_mime so that filters can be associated with
3217 *) Get multi-views working again. We were setting the path_info
3218 field incorrectly if we couldn't find the specified file.
3221 *) Fix 304 processing. The core should never try to send the headers
3222 down the filter stack. Always, just setup the table in the request
3223 record, and let the header filter convert it to data that is ready
3227 *) More fixes for the proxy. There are still bugs in the proxy code,
3228 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
3232 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
3235 *) APR: Add new apr_getopt_long function to handle long options.
3236 [B. W. Fitzpatrick <fitz@red-bean.com>]
3238 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
3239 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
3240 hostname resolution/address string parsing and building
3241 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
3242 of one of the apr_sockaddr_t structures for a socket. Change
3243 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
3245 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
3246 I have proxied pages with it, cleanup will commence soon.
3249 *) Make the proxy work with filters. This isn't perfect, because we
3250 aren't dealing with the headers properly. [Ryan Bloom]
3252 *) Do not send a content-length iff the C-L is 0 and this is a head
3253 request. [Ryan Bloom]
3255 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
3256 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
3258 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
3260 *) Get the default_handler to stop trying to deal with HEAD requests.
3261 The idea is to let the content-length filter compute the C-L before
3262 we try to send the data. If we can get the C-L correctly, then we
3263 should send it in the HEAD response.
3266 *) The Header filter can now determine if a body should be sent based
3267 on r->header_only. The general idea of this is that if we delay
3268 deciding to send the body, then we might be able to compute the
3269 content-length correctly, which will help caching proxies to cache
3270 our data better. Any handler that doesn't want to try to compute
3271 the content-length can just send an EOS bucket without data and
3272 everything will just work.
3275 *) Add the referer to the error log if one is available.
3276 [Markus Gyger <mgyger@itr.ch>]
3278 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
3279 change, the root of the configuration tree has been exposed to modules
3281 [Ryan Morgan <rmorgan@covalent.net>]
3283 *) Get the core_output_filter to use the bucket interface directly.
3284 This keeps us from calling the content-length filter multiple times
3285 for a simple static request.
3288 *) We are sending the content-type correctly now.
3289 [Ryan Bloom and Will Rowe]
3291 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
3292 a bogus bytes-sent value when the only thing being sent was trailers
3293 and writev() returned an error (or EAGAIN). [Jeff Trawick]
3295 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
3296 hints file to determine which platforms define
3297 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3300 *) APR: add apr_get_home_directory() [Jeff Trawick]
3302 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
3304 *) Not all platforms have INADDR_NONE defined by default. Apache
3305 used to make this check and define INADDR_NONE if appropriate,
3306 but APR needs the check too, and I suspect other applications will
3307 as well. APR now defines APR_INADDR_NONE, which is always a valid
3308 value on all platforms.
3309 [Branko Èibej <brane@xbc.nu>]
3311 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
3312 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
3314 *) Relax the syntax checking of Host: headers in order to support
3315 iDNS. PR#6635 [Tony Finch]
3317 *) When reading from file buckets we convert to an MMAP if it makes
3318 sense. This also simplifies the default handler because the
3319 default handler no longer needs to try to create MMAPs.
3322 *) BUFF has been removed from the main server. The BUFF code will remain
3323 in the code until it has been purged from the proxy module as well.
3326 *) Byteranges have been completely re-written to be a filter. This
3327 has been tested, and I believe it is working correctly, but it could
3328 doesn't work for the Adobe Acrobat plug-in. The output almost matches
3329 the output from 1.3, the only difference being that 1.3 includes
3330 a content-length in the response, and this does not.
3333 *) APR read/write functions and bucket read functions now operate
3334 on unsigned integers, instead of signed ones. It doesn't make
3335 any sense to use signed ints, because we return the error codes,
3336 so if we have an error we should report 0 bytes read or written.
3339 *) Always compute the content length, whether it is sent or not.
3340 The reason for this, is that it allows us to correctly report
3341 the bytes_sent when logging the request. This also simplifies
3342 content-length filter a bit, and fixes the actual byte-reporing
3343 code in mod_log_config.c
3346 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
3347 it says, because it was only used by EOS and FLUSH buckets. Since
3348 neither of those are required at the end of a brigade, this was
3349 really signifying FLUSH_THE_DATA, but that can be determined better
3350 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
3351 buckets now return a length of 0, which is actually the amount of data
3352 read, so they make more sense.
3355 *) Allow the core_output_filter to save some data past the end of a
3356 request. If we get an EOS bucket, we only send the data if it
3357 makes sense to send it. This allows us to pipeline request
3358 responses. As a part of this, we also need to allocate mmap
3359 buckets out of the connection pool, not the request pool. This
3360 allows the mmap to outlive the request.
3363 *) Make blocking and non-blocking bucket reads work correctly for
3364 sockets and pipes. These are the only bucket types that should
3365 have non-blocking reads, because the other bucket types should
3366 ALWAYS be able to return something immediately.
3369 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
3370 server, but use Ctrl+Break to initiate a graceful restart
3371 instead of duplicating behavior. [John Sterling]
3373 *) Patch mod_autoindex to set the Last-Modified header based on
3374 the directory's mtime, and add the ETag header. [William Rowe]
3376 *) Merge the 1.3 patch to add support for logging query string in
3377 such a way that "%m %U%q %H" is the same as "%r".
3380 *) Port three log methods from mod_log_config 1.3 to 2.0:
3381 CLF compliant '-' byte count, method and protocol.
3384 *) Add a new LogFormat directive, %c, that will log connection
3385 status at the end of the response as follows:
3386 'X' - connection aborted before the response completed.
3387 '+' - connection may be kept-alive by the server.
3388 '-' - connection will be closed by the server.
3391 *) Expand APR for WinNT to fully accept and return utf-8 encoded
3392 Unicode file names and paths for Win32, and tag the Content-Type
3393 from mod_autoindex to reflect that charset if the the feature
3394 macro APR_HAS_UNICODE_FS is true. [William Rowe]
3396 *) Compute the content length (and add appropriate header field) for
3397 the response when no content length is available and we can't use
3398 chunked encoding. [Jeff Trawick]
3400 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
3401 so that content input filters get dechunked data when using
3402 the default handler. Also removed REQUEST_CHUNKED_PASS.
3405 *) Add mod_ext_filter as an experimental module. This module allows
3406 the administrator to use external programs as filters. Currently,
3407 only filtering of output is supported. [Jeff Trawick]
3409 *) Most Apache functions work on EBCDIC machines again, as protocol
3410 data is now translated (again). [Jeff Trawick]
3412 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
3413 the EBCDIC support. They are noops on ASCII machines, so this
3414 type of translation doesn't have to be surrounded by #ifdef
3415 CHARSET_EBCDIC. [Jeff Trawick]
3417 *) Fix mod_include. tag commands work again, and the server will
3418 send the FAQ again. This also allows mod_include to set aside
3419 buckets that include partial buckets.
3420 [Ryan Bloom and David Reid]
3422 *) Add suexec support back. [Manoj Kasichainula]
3424 *) Lingering close now uses the socket directly instead of using
3425 BUFF. This has been tested, but since all we can tell is that it
3426 doesn't fail, this needs to be really hacked on.
3429 *) Allow filters to modify headers and have those headers be sent to
3430 the client. The idea is that we have an http_header filter that
3431 actually sends the headers to the network. This removes the need
3432 for the BUFF to send headers.
3435 *) Charset translation: mod_charset_lite handles translation of
3436 request bodies. Get rid of the xlate version of ap_md5_digest()
3437 since we don't compute digests of filtered (e.g., translated)
3438 response bodies this way anymore. (Note that we don't do it at
3439 all at the present; somebody needs to write a filter to do so.)
3442 *) Input filters and ap_get_brigade() now have a input mode parameter
3443 (blocking, non-blocking, peek) instead of a length parameter.
3446 *) Update the mime.types file to the registered media types as
3447 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
3450 *) Namespace protect some macros declared in ap_config.h
3453 *) Support HTTP header line folding with input filtering.
3456 *) Mod_include works again. This should still be re-written, but at
3457 least now we can serve an SHTML page again.
3460 *) Begin to remove BUFF from the core. Currently, we keep a pointer
3461 to both the BUFF and the socket in the conn_rec. Functions that
3462 want to use the BUFF can, functions that want to use the socket,
3463 can. They point to the same place.
3466 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
3467 [Tomas "Ögren" <stric@ing.umu.se>]
3469 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
3470 associated pool goes away. (APR pipes on OS/2 were already had this
3471 logic.) This resolvs a fatal file descriptor leak with CGIs.
3474 *) The final line of the config file was not being read if there was
3475 no \n at the end of it. This was caused by apr_fgets returning
3476 APR_EOF even though we had read valid data. This is solved by
3477 making cfg_getline check the buff that was returned from apr_fgets.
3478 If apr_fgets return APR_EOF, but there was data in the buf, then we
3479 return the buf, otherwise we return NULL.
3482 *) Piped logs work again in the 2.0 series.
3485 *) Restore functionality broken by the mod_rewrite security fix:
3486 rewrite map lookup keys and default values are now expanded
3487 so that the lookup can depend on the requested URI etc.
3488 PR #6671 [Tony Finch]
3490 *) Tighten up the syntax checking of Host: headers to fix a
3491 security bug in some mass virtual hosting configurations
3492 that can allow a remote attacker to retrieve some files
3493 on the system that should be inaccessible. [Tony Finch]
3495 *) Add a pool bucket type. This bucket is used for data allocated out
3496 of a pool. If the pool is cleaned before the bucket is destroyed, then
3497 the data is converted to a heap bucket, allowing it to survive the
3501 *) Add a flush bucket. This allows modules to signal that the filters
3502 should all flush whatever data they currently have. There is no way
3503 to actually force them to do this, so if a filter ignores this bucket,
3504 that's life, but at least we can try with this.
3507 *) Add an output filter for sub-requests. This filter just strips the
3508 EOS bucket so that we don't confuse the main request's core output
3509 filter by sending multiple EOS buckets. This change also makes sub
3510 requests start to send EOS buckets when they are finished.
3513 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
3514 makes ap_bucket_destroy a return void, which is okay because it
3515 used to always return APR_SUCCESS, and nobody ever checked its
3516 return value anyway.
3517 [Cliff Woolley <cliffwoolley@yahoo.com>]
3519 *) Remove the index into the bucket-type table from the buckets
3520 structure. This has now been replaced with a pointer to the
3521 bucket_type. Also add some macros to test the bucket-type.
3524 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
3525 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
3526 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
3527 All _VAR_ flavors changes to _DATA to be absolutely clear.
3530 *) Add support for /, //, //servername and //server/sharename
3531 parsing of <Directory> blocks under Win32 and OS2.
3532 [Tim Costello, William Rowe, Brian Harvard]
3534 *) Remove the function pointers from the ap_bucket type. They have been
3535 replaced with a global table. Modules are allowed to register bucket
3536 types and use then use those buckets.
3539 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
3540 once we finish writing the request body to the cgi child process;
3541 otherwise, the client doesn't hit EOF on stdin. Small request bodies
3542 worked without this change (for reasons I don't understand), but large
3543 ones didn't. [Jeff Trawick]
3545 *) Remove file bucket specific information from the ap_bucket type.
3546 This has been moved to a file_bucket specific type that hangs off
3547 the data pointer in the ap_bucket type.
3550 *) Input filtering now has a third argument. This is the amount of data
3551 to read from lower filters. This argument can be -1, 0, or a positive
3552 number. -1 means give me all the data you have, I'll deal with it and
3553 let you know if I need more. 0 means give me one line and one line
3554 only. A positive number means I want no more than this much data.
3556 Currently, only 0 and a positive number are implemented. This allows
3557 us to remove the remaining field from the conn_rec structure, which
3561 *) Big cleanup of the input filtering. The goal is that http_filter
3562 understands two conditions, headers and body. It knows where it is
3563 based on c->remaining. If c->remaining is 0, then we are in headers,
3564 and http_filter returns a line at a time. If it is not 0, then we are
3565 in body, and http_filter returns raw data, but only up to c->remaining
3566 bytes. It can return less, but never more.
3567 [Greg Ames, Ryan Bloom, Jeff Trawick]
3569 *) mod_cgi: Write all of the request body to the child, not just what
3570 the kernel would accept on the first write. [Jeff Trawick]
3572 *) Back out the change that moved the brigade from the core_output_filters
3573 ctx to the conn_rec. Since all requests over a given connection
3574 go through the same core_output_filter, the ctx pointer has the
3578 *) Fix another bug in the send_the_file() read/write loop. A partial
3579 send by apr_send would cause unsent data in the read buffer to
3580 get clobbered. Complete making send_the_file handle partial
3581 writes to the network.
3584 *) Fix a couple of type fixes to allow compilation on AIX again
3585 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
3587 *) Fix bug in send_the_file() which causes offset to be ignored
3588 if there are no headers to send.
3591 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
3592 filter. Useful for supporting Windows 9* with a binary
3593 compiled on Windows NT.
3596 Changes with Apache 2.0a7
3598 *) Reimplement core_output_filter to buffer/save bucket brigades
3599 across multiple calls to the core_filter. The brigade will be
3600 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
3601 thresholds are hit or the EOS bucket is received.
3604 *) Create experimental filter (buffer_filter) that coalesces bytes
3605 into one large buffer before invoking the next filter in the
3606 chain. This filter is particularly useful with the current
3607 implementation of mod_autoindex when it inserted above the
3608 chunk_filter. mod_autoindex generates a lot of brigades that
3609 containing buckets holding just a few bytes each. The
3610 buffer_filter coalesces these buckets into a single large bucket.
3613 *) Add apr_sendfile() support into the core_output_filter.
3616 *) Add apr_sendv() support into the core_output_filter.
3619 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
3620 [Mike Abbott <mja@sgi.com>]
3622 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
3623 make much sense, because Apache uses buckets instead of BUFFs now.
3626 *) send_the_file now falls back to a read/write loop on platforms that
3627 do not have sendfile.
3628 [Ryan Bloom and Brian Havard]
3630 *) Install apachectl correctly, and substitute the proper values so
3631 that it works again. [Ryan Bloom]
3633 *) Better(??) handle platforms that lack sendfile().
3636 *) APR now has UUID generation/formatting/parsing support.
3639 *) Begin the http_filter. This is an input filter that understands
3640 the absolute basic amount required to parse an HTTP Request. The
3641 goal is to be able to split headers from request body before passing
3642 the data back to the other filters.
3645 *) Bring forward from 1.3.13 the config directory implementation
3648 *) install apxs if it is created
3651 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
3652 conversions. [William Rowe]
3654 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
3655 ap_add_output_filter(). [Jeff Trawick]
3657 *) Multiple build and configuration fixes
3660 -add datadir and localstatedir substitutions
3662 -fix logfilename misspelling
3663 -fix evaluation of installation dir variables and
3664 -replace $foobar by $(foobar) to be usefull in the makefile
3668 -add rules for cross-compiling in rules.mk. Okay, rule to check for
3669 $CC_FOR_BUILD is still missing
3670 -use CHECK_TOOL instead of CHECK_PROG for ranlib
3671 -add missing "AR=@AR@" to severaly Makefile.in's
3672 -cache result for "struct rlimit"
3673 -compile all helper programs with native and cross compiler
3674 and use the native version to generate header file
3675 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3677 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
3679 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3681 *) Fix a bug where a client which only sends \n to delimit header
3682 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
3683 message. Start working on ebcdic co-existance with input
3685 [William Rowe, Greg Ames]
3687 *) If mod_so is enabled in the server always create libexec, even
3688 if there are no modules installed in this directory. This is a
3689 requirement for APXS to work correctly.
3692 *) Connection oriented output filters are now stored in the
3693 conn_rec instead of the request_rec. This allows us to add the
3694 output filter in the pre-connection phase instead of the
3695 post_read_request phase, which keeps us from trying to write an
3696 error page before we have a filter to write to the network.
3697 [Ryan Bloom, Jeff Trawick, and Greg Ames]
3699 *) Cleaning up an mmap bucket no longer deletes the mmap. An
3700 mmap can be used across multiple buckets (default_handler with
3701 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
3702 the mmap itself can't be associated with the bucket.
3705 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
3708 *) Radical surgery to improve mod_isapi support under Win32.
3709 Includes a number of newer ServerSupportFunction calls, support
3710 for ReadClient (in order to retrieve POSTs greater than 48KB),
3711 and general bug fixes to more reliably load ISAPI .dll's and
3712 prevent leaking handle resources. Note: There are still
3713 discrepancies between IIS's and Apache's ServerVariables, and
3714 async calls are still not supported. Additional warnings are
3715 logged to facilitate debugging of unsupported ISAPI calls.
3718 *) Add input filtering to Apache. The basic idea for the input
3719 filters is the same as the ideas for output filters. The biggest
3720 difference is that instead of calling ap_pass_brigade, ap_get_brigade
3721 should be called, and the order of execution for the filter itself is
3722 different. When writing an output filter, a brigade is passed in,
3723 and filters operate directly on that brigade, when done, they call
3724 ap_pass_brigade. Input filters are the exact opposite. Because input
3725 is not a push operation, filters first call ap_get_brigade. When this
3726 function returns, the input filter will be left with a valid brigade.
3727 The input filter should then operate on the brigade, and return.
3730 *) Fix building on BSD/OS using its native make. The build system
3731 falls back to the BSD .include directive on that host platform.
3734 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
3735 SHA1 and plaintext password encodings. Make feature tests a
3736 bit more flexible. [William Rowe]
3738 *) Charset translation: mod_charset_lite handles output content
3739 translation in a filter. mod_charset_lite no longer ignores
3740 subrequests. A bunch of cruft related to BUFF's support for
3741 translating request and response bodies was removed.
3744 *) Move the addition of the CORE filter to the post_read_request
3745 hook in http_core.c. This removes the need to add the filter in
3746 multiple places and allows for an SSL module to be added much
3747 simpler. [Ryan Bloom]
3749 *) Fix a security problem that affects certain configurations of
3750 mod_rewrite. If the result of a RewriteRule is a filename that
3751 contains expansion specifiers, especially regexp backreferences
3752 $0..$9 and %0..%9, then it may be possible for an attacker to
3753 access any file on the web server. [Tony Finch]
3755 *) Fix a bug where errors that are detected during early request parsing
3756 don't produce visible HTTP error messages at the browser, because
3757 the core_filter wasn't present. [Greg Ames]
3759 *) Provide apr_socklen_t as a portability aid.
3760 [Victor J. Orlikowski]
3762 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
3763 as well as a comment arg to the add, adduser and update cmds.
3764 update allows the user to clear or preserve pw/groups/comment.
3765 Fixed a bug in dbmmanage that prevented the check option from
3766 parsing a password followed by :group... text. Corrected the
3767 seed calcualation for Win32 systems, and added -lsdbm support.
3770 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
3773 *) Avoid a segfault when parsing .htaccess files. An
3774 uninitialized tree pointer was passed to ap_build_config().
3777 *) Change the way that inet_addr & inet_network are checked for
3778 in APR's configure process to allow BeOS BONE to correctly
3779 find them. With this change BeOS BONE now builds from source
3780 with no problems. [David Reid]
3782 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
3783 the end of the parameters to execve() was stored in the wrong
3784 location, overlaying the storage beyond the newargs[] array and
3785 also passing uninitialized storage to execve(), which would
3786 sometimes fail with EFAULT. [Jeff Trawick]
3788 *) Fix a bug parsing configuration file containers. With a sequence
3789 like this in the config file
3791 <IfModule mod_kilroy.c>
3794 <IfModule mod_lovejoy.c>
3799 the second container would be terminated at the blank line due to
3800 sediment in the buffer from reading the prior </IfModule> and an
3801 error message would be generated for the real </IfModule> for the
3802 second container. Also due to this problem, any two characters
3803 could be used for "</" in the close of a container.
3806 *) ap_add_filter prototype changed to remove the ctx pointer. The
3807 pointer still remains in the filter structure, but it can not be
3808 a part of the ap_add_filter prototype. The reason is that when
3809 the core uses AddFilter to add a filter to the stack it doesn't
3810 know how to allocate the ctx pointer, or even how much memory should
3811 be allocated. The filters will have to be responsible for allocating
3812 the ctx memory when they need it.
3815 *) Add an AddFilter directive. This directive takes a list of filters
3816 that should be activated for the requested resource.
3819 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
3820 some other platforms). [Jeff Trawick]
3822 *) Modify mod_include to be a filter. Currently, it has only been tested
3823 on actual files, but it should work for CGI scripts too.
3826 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
3827 writes. apr_flush() for Unix: handle interrupted writes.
3830 *) NameVirtualHost can now take "*" as an argument instead of
3831 an IP address. This allows you to create a purely name-based
3832 virtual hosting server that does not have any IP addresses in
3833 the configuration file and which ignores the local address
3834 of any connections. PR #5595, PR #4455 [Tony Finch]
3836 *) Fix some compile warnings in mod_mmap_static.c
3837 [Mike Abbott <mja@sgi.com>]
3839 *) Fix chunking problem with CGI scripts. The general problem was that
3840 the CGI modules were adding an EOS bucket and then the core added an
3841 EOS bucket. The chunking filter finalizes the chunked response when it
3842 encounters an EOS bucket. Because two EOS buckets were sent, we
3843 finalized the response twice. The fix is to make sure we only send one
3844 EOS, by utilizing a flag in the request_rec.
3847 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
3848 and Win32. Previously, the first read from an apr_file_t set up via
3849 apr_put_os_file() would return a '\0'. [Jeff Trawick]
3851 *) Mod_cgid now creates a single element bucket brigade, with a pipe
3852 bucket, instead of using BUFF's and ap_r*.
3855 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
3856 [Mike Abbott <mja@sgi.com>]
3858 *) Remove ap_bopenf from buff code. This required modifying the file_cache
3859 code to use APR file's directly instead of going through BUFFs.
3862 *) Fix compile break on some platforms for mod_mime_magic.c
3863 [John K. Sterling <sterling@covalent.net>]
3865 *) Fix merging of AddDefaultCharset directive.
3866 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
3868 *) Minor revamp of the rlimit sections of code. We now test
3869 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
3870 is now "available" even if the platform doesn't support
3871 the rlimit family (it's just a noop though). [Jim Jagielski]
3873 *) Migrate the pre-selection of which MPM to use for specific
3874 platforms to hints.m4, which contains (or should contain)
3875 all platform specific "hints". [Jim Jagielski]
3877 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
3880 *) Add tables with non-string/binary values to APR.
3883 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
3886 *) Update PCRE to version 3.2. [Ryan Bloom]
3888 *) Change the way buckets' destroy functions are called so that
3889 they can be more directly used when changing the type of a
3890 bucket in place. [Tony Finch]
3892 *) Add generic support for reference-counting the resources used by
3893 buckets, and alter the HEAP and MMAP buckets to use it. Change
3894 the way buckets are initialised to support changing the type of
3895 buckets in place, and use it when setting aside TRANSIENT buckets.
3896 Change the implementation of TRANSIENT buckets so that it can be
3897 mostly shared with IMMORTAL buckets, which are now implemented.
3900 Changes with Apache 2.0a6
3902 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
3904 *) Add a chunking filter to Apache. This brings us one step closer
3905 to removing BUFF. [Ryan Bloom]
3907 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
3908 added to the stack is the last filter to be called. [Ryan Bloom]
3910 *) Apache 2.0 has been completely documented using Scandoc. The
3911 docs can be generated by running 'make docs'. [Ryan Bloom]
3913 *) Add filtered I/O to Apache. This is based on bucket brigades,
3914 Currently the buckets still use BUFF under the covers, but that
3915 should change quickly. The only currently written filter is the
3916 core filter which just calls ap_bwrite. [The Apache Group]
3918 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
3919 built with thread support. [Jeff Trawick]
3921 *) Abort configuration if --with-layout was specified and there's
3922 no layout definition file. [Ken Coar]
3924 *) Add support for '--with-port=n' option to configure. [Ken Coar]
3926 *) Add support for extension methods for the Allow response header
3927 field, and an API routine for accessing r->allowed and the
3928 list of extension methods in a unified manner. [Ken Coar]
3930 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
3931 [Rob Simonson <simo@us.ibm.com>]
3933 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
3934 APACHE_XLATE builds. [Jeff Trawick]
3936 *) A configuration file parsing problem was fixed. When the
3937 configuration file started with an IfModule/IfDefine container,
3938 only the last statement in the container would be retained.
3941 Changes with Apache 2.0a5
3943 *) Perchild is serving pages after passing them to different child
3944 processes. There are still a lot of bugs, but this does work. I
3945 have made requests against the same installation of Apache, and had
3946 different servers use different user IDs to serve the responses.
3947 This change moves to using socketpair instead of an AF_UNIX socket.
3950 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
3951 It can't seem to pass between child processes yet, but I think we
3952 are closer now than before. This moves us back to using Unix
3953 Domain Sockets. [Ryan Bloom]
3955 *) libapr functions and types renamed with apr_ prefix.
3956 #include "apr_compat.h" for 1.3.x backwards compat
3959 *) Fix problems with APR sockaddr handling on Win32. It didn't always
3960 return the right information on the local socket address.
3961 [Gregory Nicholls <gnicholls@level8.com>]
3963 *) ap_recv() on Win32: Set bytes-read to 0 on error.
3964 [Gregory Nicholls <gnicholls@level8.com>]
3966 *) Add an option to not detach from the controlling terminal without
3967 going into single process mode. This allows for much easier
3968 debugging of the process startup code. [Ryan Bloom]
3970 *) ab: don't use perror() to report the failure of an APR function.
3973 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
3974 scoreboard on graceful restarts.
3977 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
3978 An invalid ap_proc_t was passed to ap_create_process().
3981 *) Allow modules to register filters. Those filters are still
3982 never called, but this is a step in the right direction.
3983 [Ryan Bloom and Greg Stein]
3985 *) Register the mod_cgid daemon process for cleanup so that it is
3986 killed at termination if it does not die when the parent gets
3987 SIGTERM. This change is to fix occasional problems where the
3988 process stays around. Bugs in similar logic in mod_rewrite and
3989 mod_include were also fixed. [Jeff Trawick]
3991 *) Fix a bug in the time handling. Basically, we were imploding a time
3992 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
3993 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
3994 uses those two fields to adjust the time value. Because of the HTTP
3995 spec, both of those values can be zero'ed out safely. This fixes
3996 the bug correctly. [Ryan Bloom]
3998 *) Fix a couple of place in the Windows code where the wrong error
3999 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
4001 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
4003 *) Added the APR_EOL_STR macro for platform dependent differences in
4004 logfiles and other raw text (such as all APR files). Fixes logfiles
4005 not terminated with cr/lf sequences in Win32. [William Rowe]
4007 *) Move all strings functions in APR to src/lib/apr/strings and create
4008 apr_strings.h for the prototypes. [Ryan Bloom]
4010 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
4011 to repeat the syscall until we stop getting EINTR. I noticed a
4012 related problem at termination (SIGTERM) on FreeBSD when using
4013 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
4014 implementation work properly with child init. Previously, ap_lock()
4015 was essentially a no-op because all children were using different
4016 locks and thus nobody ever blocked. [Jeff Trawick]
4018 *) The htdocs/ tree has been moved out of the CVS source tree into
4019 a separate area for easier development. This has NO EFFECT on
4020 end-users or Apache installations. [Ken Coar]
4022 *) Integrate the mod_dav module for WebDAV protocol handling. This
4023 adds the dav and dav_fs modules, the SDBM library, and additional
4024 XML handling utilities. [Greg Stein]
4026 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
4029 *) Update the lib/expat-lite/ library (bring forward changes from
4030 the Apache 1.3 repository). [Greg Stein]
4032 *) If sizeof(long long) == sizeof(long), then prefer long in APR
4033 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
4035 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
4036 machines where sendfile is detected, but nobody has written ap_sendfile.
4037 [Dave Hill <ddhill@zk3.dec.com>]
4039 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
4041 *) ab would start up more connections than needed, then quit when the
4042 desired number were finished. Also fixed a logic error involving
4043 ab keepalives. [Victor J. Orlikowski]
4045 *) WinNT: Implement non-blocking pipes with timeouts to communicate
4046 with CGIs. Apache 2.0a4 had non-blocking pipes but without
4047 timeouts (i.e, if a timeout was specified, the pipe reverted to
4048 a full blocking pipe). Now the behaviour is more in line with
4049 Unix non-blocking pipes.
4052 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
4053 cache open file handles along with accept socket reuse enables
4054 Apache 2.0 to serve non-keepalive requests for static files at
4055 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
4056 and Apache 2.0 will serve almost 1200 rps on my system).
4059 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
4060 supports two config directives, mmapfile (same behavious as
4061 mod_mmap_static) and cachefile. Use the cachefile directive
4062 to cache open file handles. This directive only works on systems
4063 that have implemented the ap_sendfile API. cachefile works today
4064 on Windows NT, but has not been tested on any flavors of Unix.
4067 *) Cleanup the configuration. With the last few changes the
4068 configuration process automatically:
4069 inherits information about how to build from APR. Allowing
4070 APR to inform Apache that it should or should not use -ldl
4072 Detects which mod_cgi should be used mod_cgi or mod_cgid,
4073 based on the threading model
4075 Apache calls APR's configure process before finishing it's
4076 configuration processing, allowing for more information flow
4081 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
4082 with non-zero argument makes the socket non-blocking. BeOS and
4083 OS/2 already worked this way. [Jeff Trawick]
4085 *) ap_close() now calls ap_flush() for buffered files, so write
4086 operations work a whole lot better on buffered files.
4089 *) Fix error messages issued from MPMs which explain where to change
4090 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
4093 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
4094 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
4095 now the way that the blocking state of a pipe is manipulated.
4096 ap_block_pipe() is gone. [Jeff Trawick]
4098 *) Correct the problem where the only local host name that the IP stack
4099 can discover are 'undotted' private names. If no fully qualified
4100 domain name can be identified, the default ServerName will be set to
4101 the machine's IP address string. A warning is always provided if the
4102 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
4104 *) Repair problems with config file processing which caused segfault
4105 at init when virtual hosts were defined and which caused ServerName to
4106 be ignored when there was no valid DNS setup. [Jeff Trawick]
4108 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
4110 *) Add ap_sendfile implementation for AIX
4111 [Victor J. Orlikowski]
4113 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
4114 apr_network_io.h, and apr_thread_proc.h.
4115 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
4117 *) Bring the allocation and pool debugging code back into a working
4118 state. This will need to be tested as so far it's only been used on
4121 *) Change configuration command setup to be properly typesafe when in
4122 maintainer mode. Note that this requires a compiler that can initialise
4123 unions. [Ben Laurie]
4125 *) Turn on buffering for config file reads. Part of this was to
4126 repair buffered I/O support in Unix and implement buffered
4127 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
4129 *) Win32: Fix problem where UTC offset was not being set correctly
4130 in the access log. Problem reported on news group by Jerry Baker.
4133 *) Fix segfault when reporting this type of syntax error:
4134 "</container> without matching <container> section", where
4135 container is VirtualHost or Directory or whatever.
4138 *) Prevent the source code for CGIs from being revealed when using
4139 mod_vhost_alias and the CGI directory is under the document root
4140 and a user makes a request like http://www.example.com//cgi-bin/cgi
4141 as reported in <news:960999105.344321@ernani.logica.co.uk>
4144 *) Add support for the new Beos NetwOrking Environment (BONE)
4147 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
4148 final input char is incomplete; ap_bwrite_xlate() now handles
4149 incomplete final input chars. [Jeff Trawick]
4151 *) Yet another update to saferead/halfduplex stuff -- need to ensure
4152 that a bhalfduplex call occurs before logging or else DNS and
4153 such can delay the last packet of the response. [Dean Gaudet]
4155 *) Some syscall reduction in APR on unix -- don't seek when setting
4156 up an mmap; and don't fcntl() more than once per socket.
4159 *) When mod_cgid is started as root, the cgi daemon now switches
4160 to the configured User/Group (like other httpd processes)
4161 instead of continuing as root. [Jeff Trawick]
4163 *) The prefork MPM now uses an APR lock for the accept() mutex.
4164 It has not been getting a lock at all recently. httpd -V now
4165 displays APR's selection of the lock mechanism instead of the
4166 symbols previously respected by prefork. [Jeff Trawick]
4168 *) Change the mmap() feature test to check only for existence.
4169 The previous check required features not used by Apache.
4172 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
4173 sometimes mangled. The len parm to accept() was not
4174 initialized, leading sometimes to an endless loop of failed
4175 accept() calls on OS/390 and anywhere else that failed the call
4176 if the len was negative. Use <sys/un.h> for struct sockaddr_un
4177 instead of declaring it ourselves to fix a compilation problem
4178 on Solaris. [Jeff Trawick]
4180 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
4182 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
4184 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
4186 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
4187 initialization if ALLOC_DEBUG is defined; no known symptom
4188 otherwise. [Jeff Trawick]
4190 *) Fix typo in configure script when checking for mod_so. bash
4191 doesn't seem to have a problem but /bin/sh on Solaris does.
4192 Symptom: "./configure: test: unknown operator =="
4195 *) Rebind the Win32 NT and 9x services control into the MPM.
4196 All console, WinNT SCM and Win9x pseudo-service control code is
4197 now wrapped within the WinNT MPM.
4200 *) Make a copy of getenv("PATH") before storing for later use. Some
4201 getenv() implementations use the same storage for successive calls.
4202 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
4204 *) Server Tokens work in 2.0 again. This also propogates the change
4205 to allow just the product name in the server string using
4209 Changes with Apache 2.0a4
4211 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
4212 won't need to call it. [Greg Ames, Jeff Trawick]
4214 *) Move pre_config hook call to between configuration read and config
4215 tree walk. This allows all modules to implement pre_config hooks
4216 and know that they will be called at an appropriate time.
4219 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
4222 *) Add pre-config hooks back to all modules.
4225 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
4226 ContentDigest enabled and we can't/don't mmap the file.
4229 *) We now report the correct line number for syntax errors in config
4230 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
4232 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
4233 related bugs, and changed shmem/locking to use apr API. Shared-mem
4234 is currently disabled, however, because of problems with graceful
4235 restarts. [Ronald Tschalär]
4237 *) Fix corruption of IFS variable in --with-module= handling.
4238 Depending on the user's shell or customization thereof, there
4239 would be errors generating ap_config_auto.h later in the configure
4240 procedure. [Jeff Trawick]
4242 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
4243 isn't used (as in 1.3), except that on Unix it is now logged via
4244 ap_log_rerror() instead of by the child having STDERR_FILENO refer
4245 to the error log. [Greg Ames, Jeff Trawick]
4247 *) Add '-D' argument processing for run time configuration defines.
4250 *) Organize http_main.c as independent code, such that no code or
4251 global data is exported from it. WIN32 will dynamically link it
4252 to the server core, so this will prevent mutual dependency.
4255 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
4256 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
4259 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
4260 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
4262 *) Add mod_charset_lite for configuring character set translation.
4265 *) Add '-n' option to htpasswd to make it print its user:pw record
4266 on stdout rather than having to frob a text file. [Ken Coar]
4268 *) Fix saferead. Basically, we flush the output buffer if a read on the
4272 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
4273 a conversion is single-byte only. [Jeff Trawick]
4275 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
4276 the BeOS 5.0 documentation says that shutdown doesn't work yet.
4279 *) Fix some minor errors where pid was being manipulated as an int
4280 instead of the portable pid_t. [Roy Fielding]
4282 *) Fix some error log prints that were printing the pointer to a
4283 structure rather than the pid within the structure.
4284 [Jeff Trawick, Roy Fielding]
4286 *) ab: Fix a command-line processing bug; track bad headers in
4287 err_response; support reading headers up to 2K.
4288 [Ask Bjoern Hansen <ask@valueclick.com>]
4290 *) Fix ap_resolve_env() so that it handles new function added in a prior
4291 alpha (see "Added the capability to do ${ENVVAR} constructs in the
4292 config file.") as well as the constructs used by mod_rewrite.
4293 [Paul Reder <rederpj@raleigh.ibm.com>]
4295 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
4297 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
4298 APR to perform translation, instead of accessing the hard-coded tables
4299 in 1.3's ebcdic.c. [Jeff Trawick]
4301 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
4304 *) Add the ability to hook into the config file reading phase. Basically
4305 if a directive is specified EXEC_ON_READ, then when that directive is
4306 read from the config file, the assocaited function is executed. This
4307 should only be used for those directives that must muck with HOW the
4308 server INTERPRETS the config. This should not be used for directives
4309 that re-order or replace items in the config tree. Those changes should
4310 be made in the pre-config step.
4313 *) Add mod_example to the build system.
4316 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
4317 byte character sets. [Jeff Trawick]
4319 *) Pick up various EBCDIC fixes from 1.3 (from Martin
4320 Kraemer and Oliver Reh originally according to the change log).
4323 *) Fix a couple of problems in RFC1413 support (controlled by the
4324 IdentityCheck directive). Apache did not build the request string
4325 properly and more importantly Apache would loop forever if the
4326 would-be ident server dropped the connection before sending a
4327 properly terminated response. [Jeff Trawick]
4329 *) apxs works in 2.0.
4332 *) Reliable piped logs work in 2.0.
4335 *) Introduce a hash table implementation into APR to be used for
4336 replacing tables and other random data structures in Apache.
4339 *) Add some more error reporting to htpasswd in the case of problems
4340 generating or accessing the temporary file. Also, pass in a
4341 buffer if the implementation knows how to use it (i.e., if L_tmpnam
4342 is defined). [Ken Coar]
4344 *) Configure creates config.nice now containing your configure
4345 options. Syntax: ./config.nice [--more-options]
4348 *) Fix various return code problems in APR on Win32. For most of
4349 these, APR was returning APR_EEXIST instead of GetLastError()/
4350 WSAGetLastError(). [Jeff Trawick]
4352 *) Make piped logs work again in version 2.0
4355 *) Add VPATH support to UNIX build system of Apache and APR.
4358 *) Fix ap_tokenize_to_argv to respect the const arguments that are
4362 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
4363 Patch submitted to author.
4366 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
4367 /sbin in PATH on FreeBSD (all submitted to rse previously)
4370 *) Fix building Pthread-based MPMs on OpenBSD
4371 [Sascha Schumann] PR#26
4373 *) Fix ap_readdir() problem on systems where d_name[] field in
4374 struct dirent is declared with only one byte. (This problem only
4375 affected multithreaded builds.) This caused a segfault during
4376 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
4377 least). [Jeff Trawick]
4379 *) Fix some make-portability problems on at least Tru64, Irix
4381 [Sascha Schumann] PR#18, PR#39
4383 *) Add ap_sigwait() to support old-style sigwait() on systems
4384 like OS/390 and UnixWare.
4387 *) Add POSIX-thread flags for more platforms.
4390 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
4391 (on Unix, at least) to handle resolver errors. Fix a bug in
4392 the definition of APR_ENOMEM so that ap_strerror() can spit
4393 out the correct error message for it.
4396 Changes with Apache 2.0a3
4398 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
4401 *) API: *HOOK* macros now have an AP_ prefix
4404 *) Win32: Eliminate redundant calls to initialize winsock.
4405 [Tim Costello <timcostello@ozemail.com.au>]
4407 *) Fix bugs initializing ungetchar for pipes.
4408 [Chia-liang Kao <clkao@CirX.ORG>]
4410 *) The ab program in the src/support directory is now portable using
4414 *) Support directory is being compiled when the server is built
4417 *) The configure option --with-program-name has been added to allow
4418 developers to rename the executable at configure time. This also
4419 changes the name of the config files to match the executable's name.
4422 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
4423 containing version numbers. [Martin Pool]
4425 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
4426 Unix; access_log and error_log now created with these perms; non-
4427 Unix is unaffected [Jeff Trawick]
4429 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
4430 Replaced more magic numbers with MD5_DIGESTSIZE.
4431 [William Rowe, Roy Fielding]
4433 *) Win32: Get mod_auth_digest compiling and added to the Windows
4434 build environment. Not tested and I'd be suprised if it
4435 actually works. [Bill Stoddard]
4437 *) Revamp the Win32 make environment. Makefiles have been removed and
4438 Apache.dsw created to bring together all the pieces. Create new file
4439 os/win32/BaseAddr.ref to define module base addresses (to prevent
4440 dll relocation at start-up).
4441 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
4443 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
4444 of the \015, \012, and \015\012 constants with macros.
4447 *) Add ap_xlate_open() et al for translation of text between different
4448 character sets. The initial implementation requires iconv().
4451 *) More FAQs and answers from comp.infosystems.www.servers.unix.
4452 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4454 *) CGI output is being timed out now.
4457 *) Fix the problem with dieing quietly. dupfile now takes a pool which
4458 is used by the new apr file. There is no reason to create a new file
4459 with the same lifetime as the original file.
4462 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
4463 module base addresses. This will help shooting seg faults
4464 in the field. [William Rowe <wrowe@lnd.com>]
4466 *) Update Apache on Windows documentation. Add new document
4467 describing how to compile Apache on Windows.
4468 [William Rowe <wrowe@lnd.com>]
4470 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
4471 microseconds instead of seconds. Some storage leaks and other
4472 minor bugs in related code were fixed. [Jeff Trawick]
4474 *) Win32: First cut at getting mod_isapi working under 2.0
4475 [William Rowe <wrowe@lnd.com>]
4477 *) First stab at getting mod_auth_digest working under 2.0
4478 quick change summary:
4479 - moved the random byte generation (ap_generate_random_bytes) into APR
4480 - now uses ap_time_t
4481 - compiles and runs on linux
4483 [Brian Martin <bmartin@penguincomputing.com>]
4485 *) Win32: Move the space stripping of physical service names
4486 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
4487 unresolved symbol. Add dependency checking to the
4488 CreateService call to ensure TCPIP and AFP (winsock) is started
4490 [William Rowe <wrowe@lnd.com>]
4492 *) Win32: Add code to perform latebinding on functions that may
4493 not exist on all levels of Windows where Apache runs. This
4494 is needed to allow Apache to start-up on Win95/98. All calls
4495 to non portable functions should be protected with
4496 ap_oslevel checks to prevent runtime segfaults.
4497 [William Rowe <wrowe@lnd.com>]
4499 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
4501 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
4503 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
4504 This addresses PR 1623. Still need to address timing out runaway
4505 CGI scripts. [Bill Stoddard]
4507 *) Win32: Make ap_stat Windows 95/98 friendly
4508 [William Rowe <wrowe@lnd.com>]
4510 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
4511 always fail. Need to initialise the dwOSVersionInfoSize member of the
4512 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
4515 The patch also enhances ap_get_oslevel (and the associated enum) to
4516 handle selected service packs for NT4, and adds recognition for
4517 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
4518 we can use ReadFileScatter and WriteFileGather in readwrite.c.
4519 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
4521 *) Get mod_rewrite building and running, and mod_status building for Win NT
4522 [Allan Edwards <ake@raleigh.ibm.com>]
4524 *) Patch to port mod_auth_db to the 2.0 api and also to support
4525 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
4526 2.7.7. It should work with version 1 as well but I haven't tested it.
4527 [Brian Martin <bmartin@penguincomputing.com>]
4529 *) Get APR DSO code working under Windows. Includes cross platform
4531 [Tim.Costello@BTFinancialgroup.com]
4533 *) Fix some of the Windows APR time functions.
4536 *) FAQ changes related to tidying up historical documents on the web site.
4537 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4539 *) Move Windows DSO code into APR.
4542 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
4543 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
4544 at build time. At this point, the server will not compile on Windows because
4545 of the recent DSO commits. Fixing those next.
4546 [Bill Rowe & Bill Stoddard]
4548 *) Added error checking for file I/O APR routines.
4549 [Jon Travis <jtravis@covalent.net>]
4551 *) APR: Don't use the values of resolver error codes for the
4552 corresponding APR error codes. On Unix and Win32, return the
4553 proper APR error code after a resolver error. [Jeff Trawick]
4555 Changes with Apache 2.0a2
4557 *) Renamed the executable back to httpd on all platforms other
4561 *) Allow BeOS to survive restarts, log properly and a few
4562 small things it had problems with due to the way it setup
4563 users and groups. [David Reid]
4565 *) Get mod_rewrite working with APR locks
4566 [Paul Reder <rederpj@raleigh.ibm.com>]
4568 *) Actually remove the sempahore when the lock cleanup routine
4569 is called on BeOS. [David Reid]
4571 *) Clear hook registrations between reads of the config file.
4572 When DSOs are unloaded and re-loaded the old hook pointers may
4573 no longer be valid. This fix eliminates potential segfaults.
4574 [Allan Edwards <ake@raleigh.ibm.com>]
4576 *) Fix a problem with Sigfunc not being defined or bypassed
4577 if sigaction() wasn't found. [Jim Jagielski]
4579 *) Fix the locking mechanism on BSD variants. They now use fcntl
4580 locks. This allows the server to start and serve pages.
4583 *) First cut at getting the Win32 installer to work
4584 [William Rowe <wrowe@lnd.com>]
4586 *) Get htpasswd compiling under Windows
4587 [William Rowe <wrowe@lnd.com>]
4589 *) Change the log message for a bind() failure to show the
4590 interface and port number. [Jeff Trawick]
4592 *) Import the documentation from 1.3.12 and bring parts of it
4593 up-to-date with respect to the changes that have occurred
4597 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
4598 now logged correctly on BeOS.
4601 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
4602 Makefile.win includes the same user interface as the old
4604 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
4606 *) Win32 exec now uses COMSPEC environment string for command
4607 shell path resolution.
4608 [William Rowe <wrowe@lnd.com>] PR#3715
4610 *) Win32: ap_connect() was not returning correct error condition
4612 [Allen Prescott <allen@clanprescott.com>]
4614 *) Win32: ap_open() was broken on Win9x because an NT-specific
4615 flag was passed to CreateFile. ap_puts() added an unnecessary
4617 [Jeff Trawick <trawick@us.ibm.com>]
4619 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
4620 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
4621 confusing ee/et name and made all extensions language/dialect
4622 rather than country reflecting. Changed example files to
4623 explicit reflect the ISO charset and added a few common
4624 ones to the example config [dirkx]
4626 *) Extend external module capability. To use this, you call
4627 configure with --with-module=path/to/mod1,path/to/mod2,etc.
4630 *) Backported the various "default charset" fixes from 1.3.12,
4631 including the AddDefaultCharset directive. [Jim Jagielski]
4633 *) Added the capability to do ${ENVVAR} constructs in the
4634 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
4635 it does this on a line by line basis; i.e. if the envvar
4636 expands to something with spaces you have to protect it
4637 by adding quotes around it (Unless of course you expect it
4638 to contains more than one argument. Alternatively you
4639 can compile it on a per token basis; which is what people
4640 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
4641 hampers fancier hacks.
4642 [Dirk-Willem van Gulik]
4644 *) Changed the 'ErrorDocument' syntax in that it NO longer
4645 supports the asymetric
4647 ErrorDocument 301 "Some message
4649 Note the opening " quote, without a closing quote. It now
4650 has either the following syntaxes
4652 ErrorDocument XXX /local/uri
4653 ErrorDocument XXX http://valid/url
4654 ErrorDocument XXX "Some Message"
4656 The recognition heuristic is: if it has a space it
4657 is a message. If it has no spaces and starts with a /
4658 or is a valid URL then treat it that way. Otherwise it
4659 is assumed to be a message.
4661 This breaks backward compatibility but makes live a hell
4662 of a lot easier for GUI's and config file parsers.
4663 [Dirk-Willem van Gulik]
4665 *) Changed 'CacheNegotiatedDocs' from its present/not-present
4666 syntax into a 'on' or 'off' syntax. As it currently is the
4667 only non nesting token which uses NO_ARGS and thus is an
4668 absolute pain for any config interface automation. This
4669 breaks backward compatibility. [Dirk-Willem van Gulik]
4671 *) Add ability to add external modules to the build process. This is
4672 done with --with-module=/path/to/module. Modules can only be added
4673 as static modules at this point.
4676 Changes with Apache 2.0a1
4678 *) Fix FreeBSD 3.3 core dump.
4679 Basically, ap_initialize() needs to get called before
4680 create_process(), since create_process() passes op_on structure
4681 to semop() to get a lock, but op_on isn't initialized until
4682 ap_initialize() calls setup_lock(). Here is a slight
4683 rearrangement to main() which calls ap_initialize() earlier...
4684 [Jeff Trawick <trawick@us.ibm.com>]
4686 *) Enable Apache to use sendfile/TransmitFile API
4687 [Bill Stoddard, David Reid, Paul Reder]
4689 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
4693 *) Make file I/O and network I/O writev/sendv APIs consistent.
4694 Eliminate use of ap_iovec_t and use Posix struct iovec.
4695 Use seperate variable on ap_writev to set the number of iovecs
4696 passed in and number of bytes written.
4699 *) Adapt file iol to use APR functions. Replaced ap_open_file()
4700 with ap_create_file_iol(). ap_create_file_iol() requires that
4701 the file be opened prior to the call using ap_open().
4704 *) Port mod_include and mod_cgi to 2.0
4705 [Paul Reder, Bill Stoddard]
4707 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
4708 bytes_read/bytes_written is always valid (never -1). Plus
4709 some fixes to buff.c to correct problems introduced by the
4710 errno => ap_status_t changes a while back. Plus a fix to
4711 chunked encoding introduced right at the beginning of 2.0.
4714 *) Revamped UNIX build system to use autoconf and libtool.
4715 [Manoj Kasichainula, Sascha Schumann]
4717 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
4719 *) More rigorous checking of Host: headers to fix security problems
4720 with mass name-based virtual hosting (whether using mod_rewrite
4721 or mod_vhost_alias).
4722 [Ben Hyde, Tony Finch]
4724 *) Add back support for UseCanonicalName in <Directory> containers.
4725 [Manoj Kasichainula]
4727 *) Added APLOG_STARTUP log type. This allows us to write an error
4728 message without any of the date and time information. As a part
4729 of this change, I also removed all of the calls to fprintf(stderr
4730 and replaced them with calls to ap_log_error using APLOG_STARTUP
4731 writing to stderr is no longer portable, because we don't direct
4732 stderr to the error log on all platforms.
4735 *) Convert error logging functions to take errno as an argument.
4736 This makes our error logs more portable, because some Windows API's
4737 don't set errno. This change allows us to still output a valid
4738 message on all of our platforms.
4741 *) mod_mime_magic runs in 2.0-dev now.
4742 [Paul Reder <rederpj@raleigh.ibm.com>]
4744 *) sendfile has been added to APR.
4745 [John Zedlewski <zedlwski@Princeton.EDU>]
4747 *) buff.c has been converted to no longer use errno.
4748 [Manoj Kasichainula]
4750 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
4751 interface adaption to APR functions did it. [Martin Kraemer]
4753 *) Support DSOs properly on 32-bit HP-UX 11.0
4754 [Dilip Khandekar <dilip@cup.hp.com>]
4756 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
4757 [Ralf S. Engelschall]
4759 *) Cleaned APR build environment integration and bootstrap APR
4760 automatically for developers from src/Configure.
4761 [Ralf S. Engelschall]
4763 *) Fixed building of src/support/htpasswd.c
4764 [Ralf S. Engelschall]
4766 *) When generating the Location: header, mod_speling forgot
4767 to escape the spelling-fixed uri. (Forw-Port from 1.3)
4770 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
4772 *) Change all pools to APR contexts. This is the first step to
4773 incorporating APR into Apache. [Ryan Bloom]
4775 *) Move "handler not found" warning message to below the check
4776 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
4777 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
4779 *) Support line-continuation feature in config.option file and
4780 allow the loading of multiple option sections at once via
4781 ``--with-option=<section1>,<section2>,...''
4782 [Ralf S. Engelschall]
4784 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
4786 Changes with Apache MPM
4788 *) Use asynchronous AcceptEx() and a completion port to accept and
4789 dispatch connections to threads in Windows NT/2000.
4792 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
4795 *) Implement the APACI --with-option facility
4796 (per default used the config.option file).
4797 [Ralf S. Engelschall]
4799 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
4801 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
4802 Replace pre_connection module call with a register_hook call and
4803 implement pre_connection as a hook. The intent is that these hooks will
4804 be extended to allow Apache to be multi-protocol, and also to allow the
4805 calling order to be specified on a per-hook/per-module basis.
4808 *) Implement mpm_* methods as "modules". Each method gets its own
4809 subdir in src/modules (eg: src/modules/prefork). Selection
4810 of method uses Rule MPM_METHOD. [Jim Jagielski]
4812 *) Port the hybrid server from the apache-apr repository as
4813 mpm_mpmt_pthread. [Manoj Kasichainula]
4815 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
4816 amongst the unix MPMs.
4818 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
4819 signal handling for the new world order. [Dean Gaudet]
4821 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
4822 of alloc.c for now. [Dean Gaudet]
4824 *) Handle partial large writes correctly. [Ben Laurie]
4826 *) Eliminate conn_rec's pointer to server. All it knows is the base server
4827 based on IP/port. [Ben Laurie]
4829 *) Port a bunch of modules to the new module structure.
4830 ["Michael H. Voase" <mvoase@midcoast.com.au>]
4832 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
4834 *) Basic restructuring to introduce the MPM concept; includes various
4835 changes to the module API... better described by
4836 docs/initial_blurb.txt. [Dean Gaudet]
4838 Changes with Apache pthreads
4840 *) New buff option added: BO_TIMEOUT. It describes the timeout for
4841 buff operations (generally over a network).
4842 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
4844 *) Created http_accept abstraction. Added 4 new functions (not exported):
4845 init_accept(), begin_accepting_requests(), get_request(),
4846 stop_accepting_requests() [Bill Stoddard]
4848 *) Fix to ap_rprintf call that allows mod_info to work properly.
4849 [James Morris <jmorris@intercode.com.au>]
4851 *) user and ap_auth_type fields were moved from connection_rec to
4852 request_rec. [Ryan Bloom]
4854 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
4855 needed in a threaded server.
4857 *) Initial pthread implementation from from Dean's apache-nspr code.
4858 [Bill Stoddard, Ryan Bloom]
4861 Changes with Apache 1.3.9
4863 *) Remove bogus error message when a redirect doesn't set Location.
4864 Instead, use an empty string to avoid coredump if the error message
4865 was supposed to include a location. [Roy Fielding]
4867 *) Don't allow configure to include mod_auth_digest unless it is
4868 explicitly requested, even if the user asked for all modules.
4871 *) Translate module names to dll names for OS/2 so that they are no more
4872 than 8 characters long and have an extension of "dll" instead of "so".
4875 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
4876 Fix test-compile check to check for randbyte instead of trand32.
4877 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
4878 and tweak to make Amaya happier. [Ronald Tschalär]
4880 *) Ensure that the installed expat include files are world readable,
4881 just like the other header files. [Martin Kraemer]
4883 *) Fixed generated AddModule adjustments in APACI's `configure' script
4884 in order to allow (new) modules like mod_vhost_alias to be handled
4885 correctly (which was touched by the adjustments for mod_alias).
4886 [Ralf S. Engelschall]
4888 *) For binary builds, add -R flag to apachectl to work around the lack of
4889 an absolute path to the ./libexec directory where the libhttp.ep file
4890 is needed for SHARED_CORE architectures. [Randy Terbush]
4892 *) WIN32: Create the CGI script process as DETACHED. This may solve the
4893 problem observed by some Win95/98 users where they get CGI script
4894 output sent to the console. [Bill Stoddard]
4896 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
4897 routines are now called ap_base64* and are 'plain' (i.e., no
4898 pool access or anything clever). Inside util.c the routines acting
4899 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
4900 The oddly named ap_uuencode(), ap_uudecode() are kept around for
4901 now but deprecated. [dirkx]
4903 *) Clean up the base64 and SHA1 additions and make sure they are
4904 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
4905 files. [Roy Fielding]
4907 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
4908 checking. Allow compiling on VS 6.0. [Randy Terbush]
4910 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
4912 *) Use TestCompile to search for the truerand library (rather than blindly
4913 assuming its existence). If it is not found, complain (but do not
4914 exit - yet). [Martin Kraemer]
4916 *) We forgot to add the new exported function names to
4917 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
4919 *) Add description of -T command-line option to usage().
4920 [Ralf S. Engelschall]
4922 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
4923 searched only AFTER libap has been searched, because libap needs
4924 some symbols from libos. [Martin Kraemer]
4926 *) Fix conflict with original mod_digest related to the symbol of the
4927 module dispatch list (which has to be unique for DSO and follow the
4928 usual conventions for the installation procedure).
4929 [Ralf S. Engelschall]
4931 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
4932 for other platforms as well. [Martin Kraemer]
4934 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
4935 types by AP_LONG and replace reference to renamed variable 'ubuf'
4936 by 'buffer'. [Martin Kraemer]
4938 Changes with Apache 1.3.8 [not released]
4940 *) Flush the output buffer immediately after sending an error or redirect
4941 response, since the result may be needed by the client to abort a
4942 long data transfer or restart a series of pipelined requests.
4943 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
4945 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
4946 [Ian Turner <iant@sequent.com>] PR#4735
4948 *) Local struct mmap in http_core.c conflicted with system structure
4949 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
4951 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
4952 [Ronald Tschalär <ronald@innovation.ch>]
4954 *) Fix a memory leak where the module counts were getting messed
4955 up across restarts. [David Harris <dharris@drh.net>]
4957 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
4958 properly in mod_access.
4959 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
4961 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
4962 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
4964 *) PORT: Support for compaq/tandem/com.
4965 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
4967 *) Added SHA1 password encryption support to easy migration from
4968 Netscape servers. See support/SHA1 for more information.
4969 Caused the separation of ap_md5.c into md5, sha1 and a general
4970 ap_checkpass.c with just a validate_passwd routine. Added a
4971 couple of flags to support/htpasswd. Some reuse of the to64()
4972 function; hence renamed to ap_to64().
4973 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
4975 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
4976 with ASCII/EBCDIC conversions in "ident" query.
4977 [David McCreedy <McCreedy@us.ibm.com>]
4979 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
4980 Change "Power Macintosh" to Power* so if uname prints "Power Book"
4981 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
4983 *) Fix SIGSEGV on some systems because the Vary fix below included
4984 a call to table_do with a variable argument list that was not
4985 NULL terminated. Replaced with better implementation. [Roy Fielding]
4987 Changes with Apache 1.3.7 [not released]
4989 *) The "Vary" response header field is now sanitised right before
4990 the header is sent back to the client. Multiple "Vary" fields
4991 are combined, and duplicate tokens (e.g., "Vary: host, host" or
4992 "Vary: host, negotiate, host, accept-language") are reduced to
4993 single instances. This is a better solution than the force-no-vary
4994 one (which is still valid for clients that can't cope with Vary
4995 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
4997 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
4999 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
5000 least on Linux and FreeBSD for now.
5003 *) Win32: More apache -k restart work. Restarts are now honored
5004 immediately and connections in the listen queue are -not- lost.
5005 This is made possible by the use of the WSADuplicateSocket()
5006 call. The listeners are opened in the parent, duplicated, then
5007 the duplicates are passed to the child. The original listen sockets
5008 are not closed by the parent across a restart, thus the listen queue
5010 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5012 *) Fix handling of case when a client has sent "Expect: 100-continue"
5013 and we are going to respond with an error, but get stuck waiting to
5014 discard the body in the pointless hope of preserving the connection.
5015 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
5017 *) Fix 'configure' to work correctly with SysV-based versions of
5018 'tr' (consistent with Configure's use as well). [Jim Jagielski]
5020 *) apxs: Add "-S var=val" option which allows for override of CFG_*
5021 built-in values. Add "-e" option which works like -i but doesn't
5022 install the DSO; useful for editing httpd.conf with apxs. Fix
5023 editing code so that multiple invocations of apxs -a will not
5024 create duplicate LoadModule/AddModule entries; apxs can now be
5025 used to re- enable/disable a module. [Wilfredo Sanchez]
5027 *) Win32: Update the server to use Winsock 2. Specifically, link with
5028 ws2_32.lib rather than wsock32.lib. This gives us access to
5029 WSADuplcateSocket() in addition to some other enhanced comm APIs.
5030 Win 95 users may need to update their TCP/IP stack to pick up
5031 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
5032 [Bill Stoddard stoddard@raleigh.ibm.com]
5034 *) Win32: Redirect CGI script stderr (script debug info) into the
5035 error.log when CGI scripts fail. This makes Apache on Win32
5036 behave more like Unix.
5037 [Bill Stoddard stoddard@raleigh.ibm.com]
5039 *) Fixed `httpd' usage display: -D was missing.
5040 [Ralf S. Engelschall] PR#4614
5042 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
5043 [Ralf S. Engelschall] PR#4561, PR#4562
5045 *) OS/2: Fix problem with accept lock semaphores where server would die with
5046 "OS2SEM: Error 105 getting accept lock. Exiting!"
5047 [Brian Havard] PR#4505
5049 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
5050 [Randy Terbush <randy@covalent.net>]
5052 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
5053 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
5055 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
5056 command potentially _is_ GCC. [Ralf S. Engelschall]
5058 *) Fix apxs build issues on AIX
5059 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
5061 *) DocumentRoot Checking: Under previous versions, when Apache
5062 first started up, it used to do a stat of each DocumentRoot to
5063 see if it existed and was a directory. If not, then an error
5064 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
5065 does not exist, you will get error messages in error_log. If
5066 the '-t' command line option is used (to check the configuration)
5067 the check of DocumentRoot IS performed. An additional command
5068 line option, '-T', has been added if you want to avoid the
5069 DocumentRoot check even when checking the configuration.
5072 *) Win32: The query switch "apache -S" didn't exit after showing the
5073 vhost settings. That was inconsistent with the other query functions.
5074 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
5076 *) Win32: Changed behaviour of apache -k restart.
5077 Previously, the server would drain all connections in the stack's
5078 listen queue before honoring the restart. On a busy server, this
5079 could take hours. Now, a restart is honored almost immediately.
5080 All connections in Apache's queues are handled but connections in
5081 the stack's listen queue are discarded. Restart triggered by
5082 MaxRequestPerChild is unchanged.
5083 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5085 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
5086 the accept loop. Good for a 5% performance boost. Cleaned up
5087 parent/child process management code.
5088 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5090 *) Added ceiling on file size for memory mapped files.
5091 [John Giannandrea <jg@meer.net>] PR#4122
5093 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
5094 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
5095 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
5097 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
5098 use this at least for Expat. [Ralf S. Engelschall]
5100 *) Allow .module files to specify libraries with Lib:.
5103 *) Allow SetEnvIf[NoCase] to test environment variables as well
5104 as header fields and request attributes. [Ken Coar]
5106 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
5107 content-types are "text/html;parameters". PR#4524 [Ken Coar]
5109 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
5110 never accepted into any standard, and it opens up certain DoS
5111 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
5113 *) TestCompile updated. We can now run programs and output the
5114 results during the Configure process. [ Jim Jagielski]
5116 *) The source is now quad (long long) aware as needed. Specifically,
5117 the Configure process determines the correct size of off_t and
5118 *void. When the OS/platform/compiler supports quads, ap_snprintf()
5119 provides for the 'q' format qualifier (if quads are not available,
5120 'q' is silently "demoted" to long). [Jim Jagielski]
5122 *) When the username or password fed to htpasswd is too long, include the
5123 size limit in the error message. Also report illegal characters
5124 (currently only ':') in the username. Add the size restrictions
5125 to the man page. [Ken Coar]
5127 *) Fixed the configure --without-support option so it doesn't result in
5128 an infinite loop. [Marc Slemko]
5130 *) Piped error logs could cause a segfault if an error occured
5131 during configuration after a restart.
5132 [Aidan Cully <aidan@panix.com>] PR#4456
5134 *) If a "Location" field was stored in r->err_headers_out rather
5135 than r->headers_out, redirect processing wouldn't find it and
5136 the server would core dump on ap_escape_html(NULL). Check both
5137 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message

5140 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
5141 of the Expat 1.0.2 distribution. [Greg Stein]
5143 *) Replace regexec() calls with calls to a new API stub function
5144 ap_regexec(). This solves problems with DSO modules which use the regex
5145 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
5147 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
5148 environment variables can be set according to the protocol version
5149 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

5166 *) Support for server-parsed and multiview-determined ReadmeName and
5167 HeaderName files in mod_autoindex. Removed the restriction on
5168 "/"s in ReadmeName and HeaderName directives since the *sub_req*
5169 routines will deal with the access issues. (It's now possible to

5210 greater). Use Mac OS X Server layout for now. Clean up dyld code
5211 in unix/os.c, and don't install the dyld error handlers, which
5212 are no longer needed in Mac OS. [Wilfredo Sanchez]
5214 *) Rename Rhapsody layout to "Mac OS X Server". Change install
5215 locations to appropriate ones for user-built (as opposed to
5216 system) installs. [Wilfredo Sanchez]
5218 *) Modify mod_autoindex's handling of AddDescription so that the
5219 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
5221 *) Add functionality to the install-bindist.sh script created by
5222 binbuild.sh to use tar when copying distribution files to the
5223 serverroot. This allows upgrading an existing installation
5224 without nesting the new distribution in the old.
5226 install-bindist.sh now detects the local perl5 path to install
5227 apxs and dbmmanage with proper path to perl interpreter.
5229 Add an install-binsupport target which copies the source files
5230 for apxs and dbmmanage to bindist to allow these scripts to
5231 be properly installed relative to the destination serverroot.

5348 htpasswd utility was limiting passwords to only 8 characters.
5351 *) EBCDIC platforms: David submitted patches for two bugs in the
5352 MD5 digest port for EBCDIC machines:
5353 a) the htdigest utility overwrote the old contents of the digest file
5354 b) the Content-MD5 header value (ContentDigest directive) was wrong
5355 when the returned file was not converted from EBCDIC, but was a
5356 binary (e.g., image file) in the first place.
5357 [David McCreedy <mccreedy@us.ibm.com>]
5359 *) support/htpasswd now permits the password to be specified on the

5398 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
5399 a roughly 5 fold speed up. [Brian Havard]
5401 *) proxy ftp: instead of using the hardwired string "text/plain" as
5402 a fallback type for files served by the ftp proxy, use the
5403 ap_default_type() function to determine the configured type.
5404 This allows for special configurations like
5405 <Directory proxy:ftp://some.host>
5406 DefaultType gargle/blurb
5408 Additionally, add the Content-Encoding: header to FTP proxy replies
5409 when the encoding is defined (by the AddEncoding directive).
5410 Because it was missing, it was almost impossible to browse compressed
5411 files using the FTP proxy (works now perfectly in Communicator).
5412 The ftp proxy now also returns the Date: and Server: header lines (if not
5413 much else... This code is "somewhat" broken) like normal requests do.
5416 *) Be more smart in APACI's configure script when determining the UID/GID
5417 for User/Group directives and use the determined UID/GID to initialize
5418 the permissions on the proxycachedir.
5419 [Dirk-Willem van Gulik, Ralf S. Engelschall]
5421 *) Changed the forking-prior-to-cleanup in the proxy module to first

5423 the number of fork()s from one/request to just the odd one an hour.
5424 [Dirk-Willem van Gulik]

5454 methods can be access controlled. [Roy Fielding] PR#3821
5456 *) Added PassAllEnv; makes server's entire environment available
5457 to CGIs and SSIs executed within directive's scope. [Ken Coar]
5459 *) ap_uuencode() always added two trailing '='s and encoding of
5460 8 bit characters on a machine with signed char may produced
5461 incorrect results. Additionally ap_uuencode() should now
5462 work correctly on EBCDIC platforms.
5463 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
5465 *) WIN32: Binary installer now runs the configuration DLL before
5466 the reboot prompt (which is only given if MSVCRT.DLL system
5467 DLL is new or updated). This should avoid the configuration
5468 directory being empty after installation. [Paul Sutton]

5492 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
5493 for 8-bit safeness. [Dean Gaudet]
5495 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
5496 because SPARCs have a small machine-specific maximum size for the Global
5497 Offset Table which is often exceeded when compiling one of the larger
5498 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
5500 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

5527 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
5530 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
5531 to make platform installations easier. [Wilfredo Sanchez]
5533 *) In configure, do not append the target name to the directory path if
5534 the path already contains "apache". [Ralf S. Engelschall]
5536 *) SIGPIPE is now ignored by the server core. The request write routines
5537 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
5538 correctly check for output errors and mark the connection as aborted.
5539 Replaced many direct (unchecked) calls to ap_b* routines with the
5540 analogous ap_r* calls. [Roy Fielding]
5542 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
5543 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
5544 Furthermore map lookups for non-existent keys are now cached as well.
5545 Additionally "txt" maps are now parsed with simple string functions
5546 instead of using ap_pregcomp(). As a side effect a bug that prevented
5547 the usage of keys containing the "," character was fixed.
5548 The changes drastically improve the performance when large rewrite maps
5550 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

5558 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
5559 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
5561 *) Add %V to mod_log_config, this logs the hostname according to the
5562 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
5563 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
5565 *) Add support for \n and \t to mod_log_config, can be used to produce
5566 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
5568 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]

5591 characters in the range 0x80 to 0xff (for example accented characters).

5594 *) Added conditional logging based upon environment variables to
5595 mod_log_config. mod_log_referer and mod_log_agent
5596 are now deprecated. [Ken Coar]
5598 *) Allow apache acting as a proxy server to relay the real
5599 reason of a failure to a client rather than the "internal
5600 server error" it does currently. The general exposure mechanism
5601 can be triggered by any module by setting the "verbose-error-to"
5602 note to "*"; this allows more than just proxy errors to be exposed.

5609 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
5611 *) Tweak modules Makefile generated by Configure so that it handles
5612 the test case of no modules being selected. [chaz@reliant.com]
5614 *) Added a <LimitExcept method ...> sectioning directive that allows
5615 the user to assign authentication control to any HTTP method that
5616 is *not* given in the argument list; i.e., the logical negation
5617 of the <Limit> directive. This is particularly useful for controlling
5618 access on methods unknown to the Apache core, but perhaps known by
5619 some module or CGI script. [Roy Fielding, Tony Finch]
5621 *) Prevent apachectl from complaining if the PIDFILE exists but
5622 does not contain a process id, as might occur if the server is
5623 being rapidly restarted. [Wilfredo Sanchez]
5625 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]

5638 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
5639 to util.c for parsing an HTTP header field value to extract the next
5640 list item, taking into account the possible presence of nested comments,

5643 [Roy Fielding] PR#2065
5645 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
5646 code different from 500. This allows the proxy to, e.g., return
5647 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455

5654 unlike RFC 2296, because the calculation might need 12 decimal places
5655 to get the right result. [Roy Fielding]
5657 *) Remove unused code to disable transparent negotiation when
5658 negotiating on encoding only, as we now handle encoding too
5659 (though this is nonstandard for TCN), remove charset=ISO-8859-1
5660 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
5661 some debugging statements within mod_negotiation. [Koen Holtman]
5663 *) Fixed a rare memory corruption possibility in mod_dir if the index
5664 file is negotiable and no acceptable variant can be found.
5665 [Dean Gaudet, Roy Fielding, Martin Kraemer]
5667 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
5668 searching the Win32 registry for script interpreters.
5671 *) Win32: The compiled-in default filename for the error log is now
5672 error.log, which matches the default in the distributed httpd.conf.
5675 *) Win32: Any error messages from -i or -u command line options are now
5676 displayed on the console output rather than sent to the error log.
5677 Also the "Running Apache..." message is not output unless Apache is
5678 going to serve requests. [Paul Sutton]
5680 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
5681 and use a private significator ('$apr1$') to mark passwords as
5682 being smashed with our own algorithm. Also abstract the password
5683 checking into a new ap_validate_password() routine. [Ken Coar]
5685 *) Win32: The filename validity checker now allows "COM" but refuses
5686 access to "COM1" through "COM4". This allows filenames such
5687 as "com.name" to be served. [Paul Sutton] PR#3769.
5689 *) BS2000: Adapt to the new ufork() system call interface which will
5690 make subtasking easier on the OSD/POSIX mainframe environment.
5693 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
5694 ap_compat.h. [David White <david@persimmon.com>] PR#3725
5696 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.

5704 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
5706 *) SECURITY: Avoid some buffer overflow problems when escaping
5707 quoted strings. (This overflow was on the heap and we believe
5708 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
5710 *) Let src/Configure be aware of CFLAGS options starting with plus
5711 signs as it's the case for the HP/UX compiler.
5712 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
5714 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
5715 and check to see if the tar we wind up with supports '-h'.
5716 [Jim Jagielski] PR#3671
5718 *) A consistent and conservative style for all shell scripts has been
5719 implemented. Basically, all shell string tests use the traditional
5720 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
5721 to protect against bare null variable strings (ie: wrapping both
5722 sides with double quotes and prepending 'x'). 'x' was chosen
5723 because it's more universal and hopefully easier for old shell
5724 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
5727 *) The status module now prints out both the main server generation as
5728 well as the generation of each process. Also, the vhost info is
5729 printed with '?notable'. [Jim Jagielski]
5731 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
5732 and this makes its functions available to things in src/support.
5735 Changes with Apache 1.3.4
5737 *) Renamed macros status_drops_connection to ap_status_drops_connection
5738 and vestigial scan_script_header to ap_scan_script_header_err,
5739 mostly for aesthetic reasons. [Roy Fielding]
5741 *) The query switch "httpd -S" didn't exit after showing the
5742 vhost settings. That was inconsistent with the other query functions.
5745 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
5746 filename to the end of the STANDARD_MODULE_STUFF. Its
5747 presence at the beginning prevented reporting of the filename
5748 for modules compiled before 1 January 1999. [Ken Coar]
5750 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
5751 to detect and prevent access to special DOS device file names.
5752 [Paul Sutton, Ken Parzygnat]
5754 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
5755 and Makefile_win32_debug.txt (debug build) that work on Win95.
5756 Run each of the following from the src directory:
5757 nmake /f Makefile_win32.txt # compiles normal build
5758 nmake /f Makefile_win32.txt install # compiles and installs
5759 nmake /f Makefile_win32.txt clean # removes compiled junk
5760 nmake /f Makefile_win32_debug.txt # compiles debug build
5761 nmake /f Makefile_win32_debug.txt install
5762 nmake /f Makefile_win32_debug.txt clean
5765 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
5766 to build binary distributions. [Lars Eilebrecht]
5768 *) IndexOptions SuppressColumnSorting only turned off making
5769 the column headers anchors; you could still change the display
5770 order by manually adding a '?N=A' or similar query string to the
5771 URL. Now SuppressColumnSorting locks in the sort order so
5772 it can't be overridden this way. [Ken Coar]
5774 *) Added IndexOrderDefault directive to supply a default sort order
5775 for FancyIndexed directory listings. [Ken Coar] PR#1699
5777 *) Change the ap_assert macro to a variant that works on all platforms.
5778 [Richard Prinz <richard.prinz@cso.net>] PR#2575
5780 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
5781 search for an underscore on dlsym() (as it's already the case
5782 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
5784 *) Small fix for mod_env.html: The module was documented as to be _not_
5785 compiled into Apache per default, although it _IS_ compiled into
5786 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
5788 *) Instead of fixing a bug in the generation procedure for config.status (a
5789 backslash was missing) we remove the bug together with it's complete
5790 context because the special cases of the past can now no longer occur
5791 because of the recent magic for the --with-layout default.
5792 [Ralf S. Engelschall] PR#3590
5794 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
5795 making sure the src/support/ tools are _forced_ to be build last (they
5796 depend on other libraries).
5797 [Markus Theissinger <markus.theissinger@gmx.de>]
5799 *) Fix installation procedure: Now that os-inline.c is actually used (a
5800 recently fixed bug prevented this) we need to also install os-include.c
5801 in addition to os.h into the PREFIX/include/ location or building of
5802 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
5804 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
5805 allow us to distinguish between a garbled DSO (or even a file which isn't
5806 an Apache module DSO at all) and a DSO which doesn't match the current
5807 Apache API. [Ralf S. Engelschall] PR#3152
5809 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
5810 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
5811 match case insensitive (this especially avoids nasty patterns like
5812 `[tT][eE][sS][tT]'). Second two additional internal map functions
5813 `escape' and `unescape' were added which can be used to escape/unescape
5814 to/from hex-encodings in URLs parts (this is especially useful in
5815 combination with map lookups).
5816 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
5818 *) Renamed the macro escape_uri() to ap_escape_uri() which was
5819 forgotten (because it was a macro) in the symbol renaming process.
5820 [Ralf S. Engelschall]
5822 *) Fix some inconsistencies related to the scopes of directives. The only
5823 user visible change is that the directives `UseCanonicalName' and
5824 `ContentDigest' now use the (more correct) `Options' scope instead of
5825 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
5827 *) Using DSO, the Server token was being mangled. Specifically, the
5828 module's token was being added first before the Apache token. This
5829 has been fixed. [Jim Jagielski]
5831 *) Major overhaul of mod_negotiation.c, part 2.
5832 - properly handle "identity" within Accept-Encoding.
5833 - allow encoded variants in RVSA negotiation and let them appear in
5834 the Alternates field using the non-standard "encoding" tag-list.
5835 - fixed both negotiation algorithms so that an explicitly accepted
5836 encoding is preferred over no encoding if "identity" is not
5837 included within Accept-Encoding.
5838 - added ap_array_pstrcat() to alloc.c for efficient concatenation
5839 of large substring sequences.
5840 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
5843 *) Major overhaul of mod_negotiation.c, part 1.
5844 - cleanups to mod_negotiation comments and code structure
5845 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
5846 support for everything in the upcoming HTTP/1.1
5847 revision (draft-ietf-http-v11-spec-rev-06.txt).
5848 - language tag matching also handles tags with more than 2
5850 - empty Accept, Accept-Language, Accept-Charset headers are
5851 processed correctly; previously an empty header would make all
5852 values acceptable instead of unacceptable.
5853 - allowed for q values in Accept-Encoding
5854 - added support for transparent content negotiation (rfc2295 and
5855 rfc2296) (though we do not implement all features in these drafts,
5856 e.g. no feature negotiation). Removed old experimental version.
5857 - implemented 'structured entity tags' for better cache correctness
5858 (structured entity tags ensure that caches which can deal with Vary
5859 will (eventually) be updated if the set of variants on the server
5861 - this involved adding a vlist_validator element to request_rec
5862 - this involved adding the ap_make_etag() function to the global API
5863 - modified guessing of charsets used by Apache negotiation algorithm
5864 to guess 'no charset' if the variant is not a text/* type
5865 - added code to sort multiviews variants into a canonical order so that
5866 negotiation results are consistent across backup/restores and mirrors
5867 - removed possibility of a type map file resolving to another type map
5868 file as its best variant
5869 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
5871 *) RFC2396 allows the syntax http://host:/path (with no port number)

5880 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
5882 *) For %v log ServerName regardless of the UseCanonicalName
5883 setting (similarly for %p). [Dean Gaudet]
5885 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
5886 rather late (too late for some invocations of TestCompile).
5887 This improves the make environment available to TestCompile and
5888 the *.module scripts. [Martin Kraemer]
5890 *) The hashbang emulation code in ap_execve.c would interpret
5891 #!/hashbang/scripts correctly, but failed to fall back to a
5892 standard shell for scripts which did NOT start with #!
5893 Now SHELL_PATH is started in these cases. [Martin Kraemer]
5895 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
5898 *) Update APXS manual page: some -q option arguments were missing
5899 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
5901 *) Cleanup the command line options: `-?' was documented to show
5902 the usage list but does it with an error because `?' is not a valid
5903 command. OTOH a lot of users expect `-h' to print such a usage list and
5904 instead are annoyed for ages by our huge unreadable list of directives.
5905 So we now changed the command line options this way:
5907 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
5908 very similar to the popular linker option.
5910 Intent: while -l gives the small list of modules, -L now gives the
5911 large list of directives implemented by these modules. This is also
5912 consistent with -v (short version info) and -V (large version info).
5914 Intent: it's now the expected option ;-)
5915 The manual page was adjusted accordingly.
5916 [Ralf S. Engelschall] PR#2714
5918 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
5919 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
5921 *) Removed recently introduced bugs and disfigurements in APACI:
5922 o fixed argument line processing: using $args was broken: It was not
5923 initialized and using args="$args $apc_option" and even args="$args
5924 \"$apc_option\"" fails in the second processing round for any arguments
5925 containing whitespaces. The only correct way is to use the construct
5926 "$@" (but not possible here) or iterate _both_ times over the implicit
5927 argument line (no argument to for-loop) which is what we now use.
5928 o make --with-layout=Apache the default without creating
5929 redundancy (copying the --with-layout block in the argument parsing
5930 loop). We achieve this by using the "$@" construct together with the
5931 `set' command to prepend --with-layout=Apache to the command line in
5932 case --with-layout is not used.
5933 o fixed auto-suffix handling now that config.layout exists.
5934 Paths which are auto-suffixed are marked with a trailing plus sign in
5935 config.layout and every path now can be marked this way (not only the
5936 four paths for which we do it currently). Additionally the suffix is
5937 no longer a static one. Instead it's now `/<target>' where <target> is
5938 the argument of the --target option or per default `httpd'.
5939 o allow also tabs (and only spaces) where we match whitespaces
5940 o various fixes and cleanups related to used shell coding style
5941 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
5942 o trimmed output of --help to fit into 80 columns
5943 [Ralf S. Engelschall]
5945 *) Added two new core API functions, ap_single_module_configure() and
5946 ap_single_module_init(), which are now used by mod_so to configure a module
5947 after loading. [Ralf S. Engelschall]
5949 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
5950 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
5951 of ap_config.h to allow serialized accept for multiport listens.
5952 [Roy Fielding, Curt Sampson] PR#3120
5954 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
5955 of ap_config.h that would skip several defines if DEFAULT_GROUP
5956 was overridden. [Roy Fielding]
5958 *) PORT: The I86 version of DGUX has support for strncasecmp and
5959 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
5961 *) Fix ordering of definitions in ap_config.h so that ap_inline is
5962 defined before it might be used. [Victor Khimenko]
5964 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
5965 [Tom Serkowski <tks@bsdi.com>] PR#3453
5967 *) Make generation of src/Configuration.apaci more robust: It failed to
5968 differenciate between modules when one module name was a postfix of
5969 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
5970 just XXX (think about totally non-standard names like "apache_ssl", too).
5971 [Ralf S. Engelschall] PR#3380
5973 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
5974 since 1.3b7) and make whitespace handling more robust (it failed horrible
5975 when whitespaces were present in the arguments of -D options).
5976 [Ralf S. Engelschall] PR#3240
5978 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
5979 creates an external package shadow tree in DIR before the local build
5980 shadow tree is generated under DIR. This way one can have the extracted
5981 Apache distribution tree read-only on NFS or CDROM and still build Apache
5982 from these sources. An automatically triggered VPATH-like mechanism is
5983 provided through the TOP variable, too.

5987 generated when, for a particular dimension, variants only vary
5988 in having or not having a value for that dimension. [Paul Sutton]
5990 *) Fix negotiation so that we prefer an encoded variant over an
5991 unencoded variant if the user-agent explicitly says it can
5992 accept that encoding. Previously we always preferred the unencoded
5994 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
5996 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
5997 and the usage page was inconsistent with the functionality and manpage.
5998 [Ralf S. Engelschall]
6000 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
6001 They can occur multiple times and their arguments (`xxx') are passed AS
6002 IS to the compiler/linker command. [Ralf S. Engelschall]
6004 *) Fixed possible (but harmless in practice) bug in the DBM lookup
6005 procedure of mod_rewrite: very long keys were truncated.
6006 [Ralf S. Engelschall]
6008 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
6009 identifier, currently "Apache" and "GNU" are pre-defined in the file
6010 config.layout. Custom layouts are possible by using FILE:ID as the
6011 argument where the layout ID is taken from FILE.
6013 The config.layout file consists of <Layout ID>..</Layout> sections
6014 where inside those sections "path_variable: path_value" pairs can be
6015 specified. These lines are converted to path_variable='path_value'.
6017 *) Add a DefaultLanguage directive so that files missing a language
6018 extension (e.g., .fr, .de) can be labelled as being some other
6019 default language. DefaultLanguage can appear in <Directory> and
6020 <Files> containers as well as .htaccess files. [Paul Sutton]
6023 *) Fix TARGET configuration when configuring and installing using
6024 APACI configure. TARGET now defines the basename of the configuration
6025 file, startup script, manual page, etc. log_error_core() now reports
6026 the server binary name given by argv[0]. TARGET can now also be defined
6027 with --target=TARGET parameter passed to APACI configure.

6133 *) Add APACI --permute-module=foo:bar option which can be used to
6134 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
6135 in the Configuration[.apaci] file. Two special and important variants are
6136 supported for the option argument: first BEGIN:foo which permutes module
6137 mod_foo with the begin of the module list, i.e. it `moves' the module to
6138 the begin of the list (gives it lowest priority). And second foo:END
6139 which permutes mod_foo with the end of the module list, i.e. it `moves'
6140 the module to the end of the list (gives it highest priority).

6143 *) Fix problem with 'apache -k shutdown' and startup event
6144 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
6147 *) The config parser wasn't correctly noticing a missing '>'
6148 on container start lines (e.g., it wouldn't spot
6149 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
6152 *) Add a 'RemoveHandler' directive which will selectively remove
6153 all handler associations for the specified file extensions.
6154 [Ryan Bloom <rbbloom@us.ibm.com>] PR#1799.
6156 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
6157 ResourceConfig directives on Win32. Also add a note to the effect
6158 of 'useless User directive ignored on Win32' to the errorlog if
6159 a User directive is encountered on Win32.
6160 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2078, 2303.
6162 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
6163 broken since Apache 1.3.1 where we took out compressing of multiple
6164 spaces in ap_cfg_getline().
6165 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
6167 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
6168 initialized correctly and the db_open() call used an invalid mode
6169 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
6171 *) PORT: DSO support for UnixWare 7
6172 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
6174 *) Merge the contents of the {srm,access}.conf-dist* files into the
6175 httpd.conf-dist* files. The srm and access files now contain
6176 only comments, and httpd.conf has all the combined contents in
6177 a rational order. [Ken Coar]
6179 *) PORT: DSO/ELF support for FreeBSD 3.0.
6180 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
6182 *) Add a "default-handler" handler that calls the default_hander()
6183 function which is normally called for static content. This allows
6184 you to override a specific handler. [Marc Slemko]
6186 *) Further simplify checking for absolute paths by replacing an
6187 hard-coded syntax check with a call to a routine we already created to
6188 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
6190 *) Log an error if we encounter a malformed "require" directive
6191 in mod_auth if we know that we know that no other module can
6192 deal with it. [Marc Slemko]
6194 *) Remove ap_private_extern method of hiding conflicting symbols
6195 on the NEXT platform because it is not correct for all versions,
6196 and the versions for which it is correct are unknown.
6197 [Wilfredo Sanchez <wsanchez@apple.com>]
6199 *) Fix inheritance of IndexOptions NameWidth and remove unintended
6200 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
6202 *) Fix per-directory config merging for cases in which a 500 error
6203 is encountered in an .htaccess file somewhere down the tree.
6206 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
6208 *) Fixed a segmentation violation in mod_proxy when a response is
6209 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
6211 Changes with Apache 1.3.3
6213 *) Added a complete implementation of the Expect header field as
6214 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
6215 response when we already know the final status, which is mighty
6216 useful for PUT responses that result in 302 or 401. [Roy Fielding]
6218 *) Remove extra trailing whitespace from the getline results as part
6219 of the protocol processing, which is extra nice because it works
6220 between continuation lines, is almost no cost in the normal case
6221 of no extra whitespace, and saves memory. [Roy Fielding]
6223 *) Added new HTTP status codes and default response bodies from the
6224 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
6225 HTTP Extension Framework (510) specifications. Did not add the
6226 WebDAV 424 and 425 codes because they are bogus. We don't use any
6227 of these codes yet, but they are now available to 3rd-party modules.
6230 *) Fix a possible race condition between timed-out requests and the
6231 ap_bhalfduplex select that might result in an infinite loop on
6232 platforms that do not validate the descriptor. [Roy Fielding]
6234 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
6235 running Apache server [Paul Sutton]
6237 *) Fix mod_autoindex bug where directories got a size of "0k" instead
6238 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
6241 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
6243 *) Add the server signature text (from the core ServerSignature directive)
6244 to the list of envariables available to scripts, SSI, and the like.
6247 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
6248 [M. Laak <maert@proinv.ee>] PR#3108
6250 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
6251 calculation in mod_status for all systems which don't have POSIX
6252 sysconf() (like UTS 2.1) and not only for the NEXT platform.
6253 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
6255 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
6256 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
6257 instead of ap_getword(..., ' ') (which parses only according to spaces
6258 but not tabs). [James Morris <jmorris@intercode.com.au>,
6259 Ralf S. Engelschall] PR#3105
6261 *) Fix the SERVER_NAME variable under sub-request situations (where
6262 `UseCanonicalName off' is used) like CGI's called from SSI pages or
6263 RewriteCond variables by adopting r->hostname to sub-requests.
6264 [James Grinter <jrg@blodwen.demon.co.uk>] PR#3111

6273 [Rob Jenson <robjen@spotch.com>, Ralf S. Engelschall] PR#3088
6275 *) Quote paths in default configuration files. [Wilfredo Sanchez]
6277 *) PORT: Remove extra HAVE_SYS_RESOURCE_H define for RHAPSODY since
6278 it is now taken care of properly by the header file tests.
6279 [Wilfredo Sanchez <wsanchez@apple.com>]
6281 *) Fix problem with scripts and filehandle inheritance on Win32.
6282 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2884, 2910
6284 *) Win32 name canonicalisation could end up using the server's
6285 working directory to fill in some blanks. [Ken Parzygnat
6286 <kparz@raleigh.ibm.com>] PR#3001
6288 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
6289 absolute paths begin with "/" -- because they don't on Win32.
6290 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
6292 *) Add [REDIRECT_]VARIANTS environment variable to mod_speling
6293 so that ErrorDocument 300 processors can reformat the list
6294 if desired. [Ken Coar] PR#2859
6296 *) Add +/- incremental prefixes to IndexOptions keywords, and
6297 enable merging of multiple IndexOptions directives. [Ken Coar]
6299 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
6300 <steve.cameron@compaq.com>]
6302 *) Reconstructed the loop through multiple htaccess file names so
6303 that missing files are not confused with unreadable files.
6306 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
6307 errno on an error, which leads to one error being mistaken for
6308 another when reading non-existent .htaccess files.
6311 *) OS/2: The new header tests get things right, need to update
6312 ap_config.h. [Brian Havard]
6314 *) The Perl %ENV hash will now be setup by default when using the
6315 mod_include `perl' command [Doug MacEachern]

6324 [Elf Sternberg <elf@halcyon.com>]
6326 *) Avoid possible line overflow in Configure: Use an awkfile to
6327 handle the creation of modules.c [Jim Jagielski]
6329 Changes with Apache 1.3.2
6331 *) Fix bug in ap_remove_module(), which caused problems for dso's
6332 who were the top_module. [Doug MacEachern]
6334 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
6335 mod_auth_db to both be friendly to users who wants to use this version
6336 and to avoid problems under platforms where only version 2.x is present.
6337 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
6339 *) When using ap_log_rerror(), make the error message available to the
6340 *ERROR_NOTES envariables by default. [Ken Coar]
6342 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
6343 You now must define a BS2000Account name for the server User.
6344 This has fewer security implications than the old approach.
6347 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
6348 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
6349 platform to make the braindead HPUX linker happy. Notice, for the module
6350 DSOs we don't have to use this, because these are loaded manually (and
6351 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
6353 *) Remove 64 thread limit on Win32.
6354 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6356 *) Remove redundant substitutions in top-level Makefile.tmpl.
6357 [Ralf S. Engelschall]
6359 *) Fix APACI's `Group' configuration adjustment - especially for Linux
6360 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
6362 *) Make PrintPath work generically instead of having one version
6363 strictly for OS/2. [Jim Jagielski, Brian Havard]
6365 *) Fix the recently introduced C header file checking: We now use the C
6366 pre-processor pass only (and no longer the complete compiler pass) to
6367 determine whether a C header file exists or not. Because only this way
6368 we're safe against inter-header dependencies (which caused horrible
6369 portability problems). The only drawback is that we now have a CPP
6370 configuration variable which has to be determined first (we do a similar
6371 approach as GNU Autoconf does here). When all fails the user still has
6372 the possibility to override it manually via APACI or src/Configuration.
6373 As a fallback for the header check itself we can directly check the
6374 existance of the file under /usr/include, too.
6375 [Ralf S. Engelschall] PR#2777
6377 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
6378 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
6379 ap_private_extern defined to hide symbols that conflict with loaded
6380 dynamic libraries on the NEXT and RHAPSODY platforms.

6398 *) Add some more LIBS for the SCO5 platform which are needed for the already
6399 used -lprot. It's actually a bug in SCO5, of course.
6400 [Ronald Record <rr@sco.com>] PR#2533
6402 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
6403 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
6405 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
6406 platform, because it's only supported under version 4.0 and higher. But
6407 because our GuessOS is still unaware of Digital UNIX versions and the
6408 -msym is just to optimize the DSO statup time a little bit it's safe and
6409 best when we leave it out now. [Ralf S. Engelschall] PR#2969
6411 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
6412 functions: First all three functions no longer fail on strings containing
6413 "%" chars and second ap_log_printf() no longer does a double-formatting
6414 (instead it directly passes through the message to be formatted to the
6415 real internal formatting function). [Ralf S. Engelschall] PR#2941
6417 *) Allow "Include" directives anywhere in the server config
6418 files (but not .htaccess files). [Ken Coar] PR#2727
6420 *) The proxy was refusing to serve CONNECT requests except to
6421 port 443 (https://) and 563 (snews://). The new AllowCONNECT
6422 directive allows the configuration of the ports to which a
6423 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
6425 *) mod_expires will now act on content that is not sent from a file
6426 on disk. Previously it would never add an Expires: header to
6427 any response that did not come from a file on disk; the only
6428 case where it still doesn't (and can't) add one for that type of
6429 content is if you are using a modification date based setting.
6430 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
6432 *) Problems encountered during .htaccess parsing or CGI execution
6433 that lead to a "500 Server Error" condition now provide explanatory
6434 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
6437 *) Add NameWidth keyword to IndexOptions directive so that the
6438 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
6441 *) Recognize lowercase _and_ uppercase `uname' results under
6442 SCO OpenServer. [David Coelho <drc@ppt.com>]
6444 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
6445 a common problem of (mis-administrated?) IIS servers, make the apache
6446 proxy immune to these errors (and ignore the duplicates, but log
6447 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
6449 *) The <IfModule and <IfDefine block starting directives now only
6450 allow exactly one argument. Previously, the optional negation
6451 character '!' could be separated by whitespace without a syntax
6452 error being reported, albeit defeating the IfModule functionality
6453 (enclosed directives would ALWAYS be executed). By using the
6454 stricter syntax, these hard-to-track errors can be avoided.
6457 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
6458 cause the standalone FancyIndexing directive to logically OR
6459 into any existing IndexOptions settings rather than wiping
6460 them out. [Ken Coar]
6462 *) Changes in ftp proxy: make URL parsing simpler by using the
6464 + Add display of the "current directory" in cases where it's
6465 different from the supplied path (e.g., ftp://user@host/ lives
6466 in /home/user, not in /, therefore clicking on "../" in the
6467 starting directory might send us to /home/).
6468 + When ftp login fails, (esp. when a user name was part of the
6469 URL already), we now return [401 Unauthorized ] to allow the
6470 browser to pop up an authorization dialog. This makes passwords
6471 slightly less visible (they don't appear in the regular log files)
6472 and implements a functionality that other www proxy servers
6476 *) Triggered by the recent "Via:" header changes, the proxy module would
6477 dump core for replies with invalid headers (e.g., duplicate
6478 "HTTP/1.0 200 OK" lines). These errors are now logged and the
6479 core dump is avoided. Also, broken replies are not cached.
6480 [Martin Kraemer] PR#2914
6482 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
6483 plop gmon.out profile data for each child [Doug MacEachern]
6485 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
6486 config.status script to be immune against arguments with whitespaces.
6487 [Yves Arrouye <yves@apple.com>] PR#2866
6489 *) Replace the inlined information grabbing stuff for the configuration
6490 adjustment feature (no --without-confadjust) with calls to a new helper
6491 script `buildinfo.sh' which is both more flexible and already proofed to
6492 be more robust against platform differences. This mainly fixes the
6493 recently occured ``sed: command garbled: ...'' problems.
6494 [Ralf S. Engelschall] PR#2776, PR#2848
6496 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
6497 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
6498 without complains after we recently added the POST feature.
6499 [Ralf S. Engelschall]
6501 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
6502 modules as API functions and we forgot them at the big symbol renaming.
6503 [Ralf S. Engelschall]
6505 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

6511 *) Add the ability to do POST requests to the ab benchmarking tool.
6512 [Kurt Sussman <kls@best.com>] PR#2871
6514 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
6515 5 to 10 because there are some users out there who always have 5 to 8
6516 variables in one RewriteRule and had to patch mod_rewrite.h for every
6517 release. So 15 should be now more than enough, even for them. (I never
6518 needed more than 4 in my RewriteRules ;-)
6519 [Ralf S. Engelschall]
6521 *) Make the proxy generate and understand Via: headers
6524 *) Change the proxy to use tables instead of array_headers for
6525 the header lines. [Martin Kraemer]
6527 *) Make sure the config.status file is not overridden when just
6528 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
6530 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
6531 provide a way to trace API changes that add functionality but do
6532 not create a compatibility issue for precompiled modules, etc.
6533 See include/ap_mmn.h for more details. [Randy Terbush]
6535 *) Fix suexec installation under `make install root=xxx' situation.
6536 [Ralf S. Engelschall]
6538 *) Extend the output of the -V switch to include the paths of all
6539 compiled-in configuration files, if they were overridden at
6540 compile time, for least astonishment of the user.
6543 *) When READing a request in ExtendedStatus mode, the "old"
6544 vhost, request and client information is not displayed.
6547 *) STATUS is no longer available. Full status information now
6548 run-time configurable using the ExtendedStatus directive.
6551 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
6552 cpu time attacks) in header parsing. Add ap_overlap_tables(),
6553 a function which can be used to perform bulk update operations
6554 on tables in a more efficient manner. [Dean Gaudet]
6556 *) SECURITY: Added compile-time and configurable limits for
6557 various aspects of reading a client request to avoid some simple
6558 denial of service attacks, including limits on maximum request-line
6559 size (LimitRequestLine), number of header fields (LimitRequestFields),
6560 and size of any one header field (LimitRequestFieldsize). Also added
6561 a configurable directive LimitRequestBody for limiting the size of the
6562 request message body. [Roy Fielding]
6564 *) Make status module aware of DNS and logging states, even if
6565 STATUS not defined. [Jim Jagielski]
6567 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
6569 *) Enhance mod_speling so that CheckSpelling can be used in
6570 <Directory> containers and .htaccess files. [Ken Coar]
6572 *) API: new ap_custom_response() function for hooking into the
6573 ErrorDocument mechanism at runtime [Doug MacEachern]
6575 *) API: new ap_uuencode() function [Doug MacEachern]
6577 *) API: scan_script_header_err_core() now "public" and renamed
6578 ap_scan_script_header_err_core() [Doug MacEachern]
6580 *) The 'status' module will now show the process pid's and their
6581 state even without full STATUS accounting. [Jim Jagielski]
6583 *) Restore the client IP address to the error log messages, this
6584 was lost during the transition from 1.2 to 1.3. Add a new
6585 function ap_log_rerror() which takes a request_rec * and
6586 formats it appropriately. [Dean Gaudet] PR#2661
6588 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
6589 whitespace in input lines -- including within quoted strings.
6591 but leading and trailing whitespace should continue to be
6592 stripped [Martin Kraemer]
6594 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
6595 the ugly use of an env. variable and use command-line args for
6596 alternate $PATH. Make more like advanced 'type's as well.
6599 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
6600 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
6601 <alain.st-denis@ec.gc.ca>] PR#2736
6603 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
6605 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
6606 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
6607 directory was renamed to src/os/os2/ for consistency.
6608 [Brian Havard, Ralf S. Engelschall]
6610 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
6611 files (here modules) against other DSO files (here shared libraries).
6612 This is done by determining a subset of LIBS which can be safely used for
6613 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
6614 disabled for all platforms to avoid problems with this (experimental)
6615 rule. But we provide it now for those people how ran into problems and
6616 want to came out by forcing linking against DSOs.
6617 [Ralf S. Engelschall] PR#2587
6619 *) Fix suEXEC start message: Has to be of `notice' level to really get

6923 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
6925 *) Improve performance of directory listings (mod_autoindex) by comparing
6926 integer keys (last-modified and size) as integers rather than converting
6927 them to strings first. Also use a set of explicit byte tests rather
6928 than strcmp() to check for parent directory-ness of an entry. Oh, and
6929 make sure the parent directory (if displayed) is *always* listed first
6930 regardless of the sort key. Overall performance winnage should be good
6931 in CPU time, instruction cache, and memory usage, particularly for large
6932 directories. [Ken Coar]
6934 *) Add a tiny but useful goody to APACI's configure script: The generation
6935 of a config.status script (as GNU Autoconf does) which remembers the used
6936 configure command and hence can be used to restore the configuration by
6937 just re-running this script or for remembering the configuration between

6941 *) Add httpd -t (test) option for running configuration syntax tests only.
6942 If something is broken it complains and exits with a return code
6943 non-equal to 0. This can be used manually by the user to check the Apache
6944 configuration after editing and is also automatically used by apachectl
6945 on (graceful) restart command to make sure Apache doesn't die on restarts
6946 because of a configuration which is now broken since the last (re)start.
6947 This way `apachectl restart' can be used inside cronjobs without having
6948 to expect Apache to be falling down. Additionally the httpd -t can be run
6949 via `apachectl configtest'.

7128 *) A zero-length name after a $ in an SSI document should cause
7129 just the $ to be in the expansion. This was broken during the
7130 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
7132 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
7133 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252
7135 *) Fix src/support/httpd.exp (DSO export file which is currently only
7136 used under AIX) because of recent changes to function names.
7137 [Ralf S. Engelschall]
7139 Changes with Apache 1.3b7
7141 *) Make sure a MIME-type can be forced via a RewriteRule even when no
7142 substitution takes place, for instance via the following rule:
7143 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
7144 requested by users in the past to force a single script without a .cgi
7145 extension and outside any cgi-bin dirs to be executed as a CGI program.
7146 [Ralf S. Engelschall] PR#2254
7148 *) A fix for protocol issues surrounding 400, 408, and
7149 414 responses. [Ed Korthof]
7151 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
7153 *) Fix discrepancy in proxy_ftp.c which was causing failures when
7154 trying to connect to certain ftpd's, such as anonftpd.
7155 [Rick Ohnemus <rick@ecompcon.com>]
7157 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
7158 logfile instead of fiddling around itself with child spawning stuff.
7159 [Ralf S. Engelschall]
7161 *) Made RefererIgnore case-insensitive.
7163 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
7166 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
7167 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
7170 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
7172 *) Fix support script `dbmmanage': It was unable to handle some sort
7173 of passwords, especially passwords with "0" chars.
7174 [Ralf S. Engelschall] PR#2242
7176 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
7177 [Ben Laurie] PR#2238
7179 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
7180 library), so CGI handling has been changed to use Win32 native handles
7181 instead of C file descriptors.
7182 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
7184 *) The proxy cache would store an incorrect content-length in the cached
7185 file copy after a cache update. That resulted in repeated fetching
7186 of the original copy instead of using the cached copy.
7187 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
7189 *) The Makefiles assumed that DSO files are build via $(LD). This
7190 is broken for two reasons: First we never defined at least LD=ld
7191 somewhere to make sure this works (it was silently assumed that most Make
7192 provide a built-in LD definition - ARGL!) and second using the generic LD
7193 variable is not the truth. Instead a special variable named LD_SHLIB is
7194 reasonable because although "ld" is usually the default, the command for
7195 building DSO files can be "libtool" or even "cc" on some systems.
7196 [Ralf S. Engelschall]
7198 *) Replace the AddVersionPlatform directive with ServerTokens which
7199 provides for more control over the format of the Server:
7200 header line. SERVER_SUBVERSION is no longer supported;
7201 all module should use the ap_add_version_component()
7202 API function instead. [Jim Jagielski]
7204 *) Support for the NCR MP/RAS 3.0
7205 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
7207 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
7208 not retrieved in src/Configure and thus was not useable.
7209 [Ralf S. Engelschall]
7211 *) Various Makefile consistency cleanups:
7212 - make OSDIR also automatically be relative to src/ like INCDIR
7213 - SUBDIRS is now generated in src/Makefile only and not in
7214 Makefile.config because it is a local define for this location.
7215 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
7216 any Makefile but make sure that at least the "-K inline" is kept in
7218 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
7219 - updated the dependencies theirself
7220 - removed not existing SHLIB variable from "clean" targets
7221 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
7222 already exists and OBJS_PIC are also just plain objects and have not
7223 directly to do with "shared" things. The only difference is that they
7224 contain PIC. So OBJS_PIC is the more canonical name.
7225 - Updated the Makefile-dependency lines for OBJS_PIC
7226 - Removed the Makefile-dependency line in Configure to avoid double
7228 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
7229 of xxx.lo as GNU libtool does with its PIC objects
7230 - reduce local complexity in modules Makefile.tmpl by moving the last
7231 existing target "depend" to the generation section in Configure, too.
7232 - removed the historical $(SPACER) which was used in the past together
7233 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
7234 is no longer needed.
7235 - force the build and run of the gen_xxx programs under main/ as the
7236 first step before building the objects because it looks cleaner
7237 [Ralf S. Engelschall]
7239 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
7242 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
7245 *) WIN32: Don't force ISAPI headers to finish with \n.
7246 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
7248 *) When opening "configuration" files (like httpd.conf, htaccess
7249 and htpasswd), Apache will not allow them to be non-/dev/null
7250 device files. This closes a DoS hole. At the same time,
7251 we use ap_pfopen to open these files to handle timeouts.
7252 [Jim Jagielski, Martin Kraemer]
7254 *) Apache will now log the reason its httpd children exit if they exit
7255 due to an unexpected signal. (It requires a new porting define,
7256 SYS_SIGLIST, which if defined should point to a list of text
7257 descriptions of the signals available. See PORTING.) [Dean Gaudet]
7259 *) WIN32: chdir() doesn't make sense in a multithreaded environment
7260 like WIN32. Before, Win32 CGI's could have had sporadic failures
7261 if a chdir call from one thread was made between another chdir call
7262 and a spawn in another thread. So, for now don't chdir for CGI scripts
7263 in WIN32. The current CGI "spec" is unclear as to whether it's
7264 necessary. Long-term fix is to either serialize the chdir/spawn combo
7265 or use WIN32 native calls to spawn a process. This temp fix was
7266 necessary to remove this as a showstopper for 1.3's release.
7269 *) Cleanup the suEXEC support in APACI and make it more safe:
7270 1. Add big fat hint in INSTALL about risks and to read the
7271 htdocs/manual/suexec.html document before using the suexec-related
7273 2. Make sure the user has at least provided one --suexec-xxxx option
7274 (specifies suEXEC parameters) in addition to --enable-suexec option.
7275 If only --enable-suexec is given APACI stops with a hint to INSTALL
7276 and htdocs/manual/suexec.html documents.
7277 3. Provide two additional --suexec-xxxx options to make the suEXEC
7278 configuration complete (especially for package maintainers who else
7279 had to patch the source tree) by providing ways to configure minimal
7280 UID/GID and safe PATH, too.
7281 [Ralf S. Engelschall]
7283 *) Cleanup of the `configure --shadow' process:
7284 - make sure the configure script creates its temporary files in the
7285 shadow tree to avoid conflicts with parallel configure runs
7286 - removed unnecessary option "-r" from "rm" call for Makefiles
7287 - make sure the configure scripts creates the shadow-wrapper Makefile
7288 only when no shadow trees already exists
7289 - make sure "make distclean" removes the shadow-wrapper Makefile but only
7290 when no more shadow trees exists
7291 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
7292 as fast (in the past it needed 70sec, now it runs just 38sec)
7293 - make sure CVS does not complain about the created files
7294 Makefille.<gnutriple> and directories src.<gnutriple>
7295 [Ralf S. Engelschall]
7297 *) Added the ap_add_version_component() API routine and the
7298 AddVersionPlatform core directive. The first allows modules to
7299 declare themselves in the Server response header field value,
7300 augmenting the SERVER_SUBVERSION define in the Configuration file
7301 with run-time settings (more useful in a loadable-module environment).
7302 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
7303 into the server version string. [Ken Coar] PR#2056
7305 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
7308 *) Emit the "Accept-Range" header for the default handler.
7309 [Brian Behlendorf] PR#1464
7311 *) Add a note to httpd.conf-dist that apache will on some systems fail
7312 to start when the Group # is set to a negative or large positive value.
7315 *) Make sure the module execution order is correct even when some modules
7316 are loaded under runtime (`LoadModule') via the DSO mechanism:
7317 1. The list of loaded modules is now a dynamically allocated one
7318 and not the original statically list from modules.c
7319 2. The loaded modules are now correctly setup by LoadModule for
7320 later use by the AddModule command.
7321 3. When the DSO mechanism for modules is used APACI's `install'
7322 target now enables all created `LoadModule' lines per default because
7323 this is both already expected by the user _and_ needed to avoid
7324 confusion with the next point and reduces the Makefile.tmpl complexity
7325 4. When the DSO mechanism for modules is used, APACI's `install'
7326 target now additionally makes sure the module list is reconstructed
7327 via a complete `ClearModuleList+AddModule...' entry.
7328 5. The support tool `apxs' now also makes sure an AddModule command
7329 is added in addition to the LoadModule command.
7330 6. The modules.c generation was extended to now contain two
7331 comments to make sure no one is confused by the confusing terminology
7332 of loading/linking (we use load=link+load & link=activate instead of
7333 the obvious load=activate & link=link :-( )
7334 This way now there is no longer a difference under execution time between
7335 statically and dynamically linked modules.
7336 [Ralf S. Engelschall]
7338 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
7339 Big Symbol Renaming. [Ralf S. Engelschall]
7341 *) Add a comment to mod_example.c showing the format of a FLAG command
7344 *) Standardized the time format in mod_status to match that of other
7345 places in the code (e.g. DATE_GMT). PR#1551
7347 *) Fix handling of %Z in timefmt strings for those platforms with no time
7348 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
7351 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
7352 feature compatible with 'UseCanonicalName off' by changing
7353 r->server->server_hostname to ap_get_server_name(). And I changed some
7354 functions which use r->server->port to use ap_get_server_port() instead,
7355 because if there's no Port directive in the config r->server->port is 0.
7358 *) get/set_module_config are trivial enough to be better off inline. Worth
7359 1.5% performance boost. [Dean Gaudet]
7361 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
7362 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
7365 *) [BS2000 security] BS2000 needs an extra authentication to initialize
7366 the task environment to the unprivileged User id. Otherwise CGI scripts
7367 would have a way to gain super user access. [Martin Kraemer]
7369 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
7370 absolute path, only log base name of logging source as is done
7371 in unix. [Martin Kraemer]
7373 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
7374 the encoding type from the Accept-Encoding header (if it's there)
7375 and use it in the response, as that's probably what it'll be expecting.
7376 [Ronald.Tschalaer@psi.ch]
7378 *) Fix to mod_alias: translate_alias_redir is dealing with
7379 a URI, not a filename, so the check for drive letters for win32
7380 and emx is not necessary. [Dean Gaudet]
7382 *) WIN32: Allow .cmd as an executable extension.
7383 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
7385 *) Make Apache header files, and some variables, C++ friendly.
7386 [Michael Anderson's <mka@redes.int.com.mx>]
7388 *) Child processes can now "signal" (by exiting with a status
7389 of APEXIT_CHILDFATAL) the parent process to abort and
7390 shutdown the server if the error in the child process was
7391 fatal enough. [Jim Jagielski]
7393 *) mod_autoindex's find_itme() was sensitive to MIME type case.
7394 [Jim Jagielski] PR#2112
7396 *) Make sure the referer_log and agent_log entries in the default httpd.conf
7397 file are also adjusted for the actual relative installation paths.
7398 [Ralf S. Engelschall] PR#2175
7400 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
7402 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
7405 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
7406 Additionally the checks for finding the vendor DSO library were moved
7407 from mod_so.c to Configure because first it needs $PLAT etc. and second
7408 mod_so already uses an abstraction layer and does not fiddle with the
7409 vendor functions itself.
7410 [Jens-Uwe Mager, Ralf S. Engelschall]
7412 *) PORT: Some optimization defines for NetBSD
7413 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
7415 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
7416 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
7418 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
7419 AIX variants should work fine, too. Even AIX 3.x should work). This is
7420 accomplished by using the free DSO emulation code from Jens-Uwe Mager
7421 which we put into a os/unix/os-dso-aix.c file.
7422 [Ralf S. Engelschall]
7424 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
7425 that we should use NET_SIZE_T == int but the include files force size_t.
7426 [Ralf S. Engelschall]
7428 *) Fix two bugs in select() handling in http_main.c.
7431 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
7432 is unset (as it is in situations like timeouts) where it is unclear
7433 whether errno is set or not. [Martin Kraemer]
7435 *) Just having APACI's localstatedir is too general and not enough for most
7436 of the systems. 1.3b6 again required manual APACI patches by package
7437 maintainers from Red Hat and FreeBSD because for their filesystem layout a
7438 little bit more flexibility in configuring the paths is needed. Hence we
7439 provide three additional configure options (--runtimedir, --logfiledir,
7440 --proxycachedir) which now can be used for more granular adjustments if
7441 --localstatedir is not enough to fit the particular needs. As a nice
7442 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
7443 [Ralf S. Engelschall]
7445 *) Make the install root for "make install" in APACI's Makefile overrideable
7446 by package authors. This way we are even more friendly to package
7447 maintainers (especially Debian and Red Hat) who build for the real prefix
7448 via "configure --prefix=/<real>" but use a different local prefix via
7449 "make root=/tmp/apache install" for rolling the package without bristling
7450 the target location on their system.
7451 [Ralf S. Engelschall]
7453 *) Workaround sed limitations in APACI's configure script by now
7454 substituting in chunks of 50 commands (because for instance HPUX's vendor
7455 sed has a limit of max. 98 commands)
7456 [Ralf S. Engelschall] PR#2136
7458 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
7459 [Ralf S. Engelschall] PR#2140
7461 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
7462 RENAMING process because they are defined as pre-processor macros instead
7463 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
7464 [Ralf S. Engelschall]
7466 *) Workaround braindead AWK's when generating ap_config.h: The split() and
7467 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
7468 [Ralf S. Engelschall] PR#2139
7470 *) Various bugfixes and cleanups for the APACI configure script:
7471 o fix IFS handling for _nested_ situation
7472 o fix Perl interpreter search: take first one found instead of last one
7473 o fix DSO consistency check
7474 o print error messages to stderr instead of stdout
7475 o add install-quiet for --shadow situation to Makefile stub
7476 o reduce complexity by avoiding sed-hacks for rule and module list loops
7477 [Ralf S. Engelschall]
7479 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
7481 *) Make sure the input field separator (IFS) shell variable is explicitly
7482 initialized correctly before _every_ `for' loop and also restored after
7483 the loops. [Ralf S. Engelschall]
7485 *) Make sure that "make install" doesn't overwrite the `mime.types' and
7486 `magic' files from an existing Apache installation. Because people often
7487 customize these for own MIME and content types.
7488 [Ralf S. Engelschall]
7490 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
7491 [Peter Galbavy, Ralf S. Engelschall] PR#2109
7493 *) Fix the path to the ScoreBoardFile in the install-config target, too.
7494 [Ralf S. Engelschall] PR#2105
7496 *) Let "configure" clear out the users parameters (provided as shell
7497 variables) to avoid side-effects in "src/Configure" when the user
7498 exported them (which is not needed, but some users do it).
7499 [Ralf S. Engelschall] PR#2101
7501 *) Provide backward compatibility from some old src/Configuration.tmpl
7502 parameter names to the canonical Autoconf-style shell variable names. For
7503 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
7504 but a hint message is displayed. [Ralf S. Engelschall]
7506 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
7507 CGI scripts from an existing Apache installation.
7508 [Ralf S. Engelschall, Jim Jagielski] PR#2084
7510 *) Make `configure --compat' more "compatible" by first
7511 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
7512 second by making sure the "avoid-bristling-suffix" /apache is not
7513 appended to sysconfdir, datadir, localstatedir and includedir when
7514 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
7516 *) NeXT required strdup() in support/logresolve.c
7517 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
7519 *) AIX required sys/select.h in support/ab.c
7520 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
7522 *) Fix the path to the MimeMagicFile in the install-config target, too.
7523 [Ralf S. Engelschall] PR#2089
7525 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
7527 *) If you start apache with the -S command line option it will dump
7528 out the parsed vhost settings. This is useful for folks trying
7529 to figure out what is wrong with their vhost configuration.
7530 (Other dumps may be added in the future.) [Dean Gaudet]
7532 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
7533 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
7536 *) Because /usr/local/apache is the default prefix the ``configure
7537 --compat'' option no longer has to set prefix, again. This way the
7538 --compat option honors a leading --prefix option. [Lars Eilebrecht]
7540 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
7541 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
7542 to avoid "discard const" warnings. [Ralf S. Engelschall]
7544 *) If a specific handler is set for a file yet the request still
7545 ends up being handled by the default handler, log an error
7546 message before handling it. This catches things such as trying
7547 to use SSIs without mod_include enabled. [Marc Slemko]
7549 *) Fix error logging for the startup case where ap_log_error() still uses
7550 stderr as the target. Now the default log level is honored here, too.
7551 [Ralf S. Engelschall]
7553 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
7554 long" errors when generating the MODULES entry for src/Makefile
7555 [Ben Hyde, Ralf S. Engelschall]
7557 *) Make sure src/Configure doesn't complain about the old directory
7558 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
7560 Changes with Apache 1.3b6
7562 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
7564 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
7565 interface via the similar but proprietary HP/UX shl_xxx-style system
7566 calls. [Ralf S. Engelschall]
7568 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
7569 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
7570 Make. [Ralf S. Engelschall]
7572 *) ++++ THE BIG SYMBOL RENAMING ++++
7573 To avoid symbol clashes with third-party code compiled into the server,
7574 we globally applied the prefix "ap_" to the following classes of
7576 - Apache provided general functions (e.g., ap_cpystrn)
7577 - Public API functions (e.g., palloc, bgets)
7578 - Private functions which we can't make static (because of
7579 cross-object usage) but should be (e.g., new_connection)
7580 For backward source compatibility a new header file named compat.h was
7581 created which provides defines for the old symbol names and can be used
7582 by third-party module authors.
7585 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
7586 problem under SVR4 is that there is no command flag to force the linker
7587 to export the global symbols of the httpd executable therewith they are
7588 available to the DSO's. Instead of problematic hacks like creating a
7589 dummy.so file (containing dummy references to all global symbols) the
7590 httpd binary is linked against, we use a clean trick stolen from Perl 5:
7591 Placing the Apache core code itself into a DSO library named libhttpd.so.
7592 This way the global symbols _HAVE_ to be exported and thus are available
7593 to any manually loaded DSO's under runtime. To reduce the impact to the
7594 user to null we go even further and create a stub httpd executable which
7595 automatically keeps track of the DSO library loading itself and thus
7596 hides the complete mechanism from the user. Although the generation of
7597 this DSO library is automatically triggered for platforms which
7598 essentially need it (mostly all SVR4-derivates) it can be also enabled
7599 manually via the Rule SHARED_CORE. This can be interesting in the future
7600 where we perhaps exploit this libhttpd.so mechanism for providing nifty
7601 features like graceful upgrades, or whatever.
7602 [Ralf S. Engelschall, Martin Kraemer]
7604 *) Build the libraries before building the rest of the tools. [Ben Hyde]
7606 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
7607 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
7608 conventions while "clean" removes only stuff created by "all" targets,
7609 "distclean" additionally removes the stuff from the configuration
7610 process. This way "make distclean" (hence the name) provides a fresh
7611 source tree as it was for distribution.
7612 [Ralf S. Engelschall]
7614 *) Allow top-level (APACI) Makefile to break on build errors
7615 the same way the src/ subtree Makefiles breaks on them by replacing the
7616 initial APACI sed-subdir-display-kludge with a more clean
7617 variable-passing-solution: variable SDP can optionally hold the subdir
7618 prefix which is consistently used for displaying the subdir movement.
7619 This way even the top-level Makefile can stop correctly on errors as the
7620 user expects. [Ralf S. Engelschall]
7622 *) Fixed ordering of argument checks for RewriteBase directive.
7623 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
7625 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
7626 indicating that a module is being compiled for dynamic loading. Also
7627 remove #define IS_MODULE from modules and add SHARED_MODULE define
7628 to the mak/dsp files. [Alexei Kosut]
7630 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
7631 since we are now logging APLOG_WARNING by default. [Roy Fielding]
7633 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
7635 *) Add documentation file and src/Configuration.tmpl entry for the
7636 experimental mod_mmap_static module. Because although it is and marked as
7637 an experimental one it is distributed and thus should be documented and
7638 prepared for configuration the same way as all others modules.
7639 [Ralf S. Engelschall]
7641 *) Add query (-q) option to apxs support tool to be able to manually query
7642 specific settings from apxs. This is needed for instance when you
7643 manually want to access Apache's header files and you need to assemble
7644 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
7645 [Ralf S. Engelschall]
7647 *) Now src/Configure uses a fallback strategy for the shared object support
7648 on platforms where no explicit information is available: If a Perl
7649 installation exists we ask it about its shared object support and if it's
7650 the dlopen-style one we shamelessly guess the compiler and linker flags
7651 for creating shared objects from Perls knowledge. Of course, the user is
7652 warning about what we are doing and informed that he should send us
7653 the guessed flags when they work. [Ralf S. Engelschall]
7655 *) Provide APACI --without-support option to be able to disable the build
7656 and installation of the support tools from the src/support/ area.
7657 Although its useful to have these installed per default we should provide
7658 a way to compile and install without them for backward-compatibility.
7659 [Ralf S. Engelschall]
7661 *) Add of the new APache eXtenSion (apxs) support tool for building and
7662 installing modules into an _already installed_ Apache package through the
7663 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
7664 this approach actually doesn't need the Apache source tree. The
7665 (APACI-installed) server package is enough, because this now includes the
7666 Apache C header files (PREFIX/include) and the new APXS tool
7667 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
7668 module authors to build their Apache modules _OUTSIDE_ the Apache source
7669 tree while avoiding them to fiddle around with the totally platform
7670 dependend way of compiling DSO files. The tool supports all ranges of
7671 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
7672 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
7673 on-the-fly generate a minimalistic Makefile and sample module for the
7674 first step to provide both a quick success event and to demonstrate the
7675 APXS mechanism to module authors. [Ralf S. Engelschall]
7677 *) Fix core dumps in use of CONNECT in proxy.
7678 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
7680 *) Modify the log directives in httpd.conf-dist files to use CustomLog
7681 so that users have examples of how CustomLog can be used.
7684 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
7685 the Apache distribution tree. Until Apache 1.3 there was no real
7686 out-of-the-box batch-capable build and installation procedure for the
7687 complete Apache package. This is now provided by a top-level "configure"
7688 script and a corresponding top-level "Makefile.tmpl" file. The goal is
7689 to provide a GNU Autoconf-style frontend which is capable to both drive
7690 the old src/Configure stuff in batch and additionally installs the
7691 package with a GNU-conforming directory layout. Any options from the old
7692 configuration scheme are available plus a lot of new options for flexibly
7693 customizing Apache. [Ralf S. Engelschall]
7695 *) The floating point ap_snprintf code wasn't threadsafe.
7696 Had to remove the HAVE_CVT macro in order to do threadsafe
7697 calling of the ?cvt() floating point routines. [Dean Gaudet]
7699 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
7701 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
7702 [Jim Jagielski] PR#1901
7704 *) BUG: Configure was using TCC and CC inconsistently. Make sure
7705 Configure knows which CC we are using. [Jim Jagielski]
7707 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
7708 was defined in a parent directory. [Lars Eilebrecht]
7710 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
7711 a generic printf-style routine that can call arbitrary output
7712 routines. Use this to replace http_bprintf.c. Add new routines
7713 psprintf(), pvsprintf() which allocate the exact amount of memory
7714 required for a string from a pool. Use psprintf() to clean up
7715 various bits of code which used ap_snprintf()/pstrdup().
7718 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
7719 ap_snprintf() has different semantics and formatting codes than
7720 snprintf(). [Dean Gaudet]
7722 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
7723 is necessary on at least Solaris where the /etc/rc?.d scripts
7724 are run with these signals ignored, and "SIG_IGN" settings are
7725 maintained across exec().
7726 [Rein Tollevik <reint@sys.sol.no>] PR#2009
7728 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
7729 used instead of lstat() and thus this flag didn't work as expected.
7730 [Rein Tollevik <reint@sys.sol.no>] PR#2010
7732 *) Fix the proxy pass-through feature of mod_rewrite for the case of
7733 existing QUERY_STRING now that mod_proxy was recently changed because of
7734 the new URL parsing stuff. [Ralf S. Engelschall]
7736 *) A few changes to scoreboard definitions which helps gcc generate
7737 better code. [Dean Gaudet]
7739 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
7740 be a signed bitfield. So mark a few bitfields as signed to
7741 ensure correct code. [Dean Gaudet]
7743 *) The default for HostnameLookups was changed to Off, but there
7744 was a problem and it wasn't taking effect. [Dean Gaudet]
7746 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
7749 *) After a SIGHUP the listening sockets in the parent weren't
7750 properly marked for closure on fork().
7751 [Jürgen Keil <jk@tools.de>] PR#2000
7753 *) Allow %2F in two situations: 1) it is in the query part of the URI,
7754 therefore not exposed to %2F -> '/' translations and 2) the request
7755 is a proxy request, so we're not dealing with a local resource anyway.
7756 Without this, the proxy would fail to work for any URL's with
7757 %2f in them (occurs quite often in
7758 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
7760 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
7762 *) Make the shared object compilation command more portable by avoiding
7763 the direct combination of `-c' & `-o' which is not honored by some
7764 compilers like UnixWare's cc. [Ralf S. Engelschall]
7766 *) WIN32: the proxy was creating filenames missing the last four
7767 characters. While this normally doesn't stop anything from
7768 working, it can result in extra collisions.
7769 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
7771 *) Now mod_proxy uses the response string (in addition to the response status
7772 code) from the already used FTP SIZE command to setup the Content-Length
7773 header if available. [Ralf S. Engelschall] PR#1183
7775 *) Reanimated the (still undocumented) proxy receive buffer size directive:
7776 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
7777 name was really too generic, added documentation for this directive to
7778 the mod_proxy.html and corrected the hyperlink to it in the
7779 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
7781 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
7782 faster [Martin Kraemer]
7784 *) Make Configure die when you give it an unknown command switch.
7787 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
7788 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
7789 and per default compiled support programs have manual pages - just to
7790 document our stuff a little bit more and to be able to do really
7791 Unix-like installations ;-) [Ralf S. Engelschall]
7793 *) Major cleanups to the Configure script to make it and its generated
7794 Makefiles again readable and maintainable: add SRCDIR option, removed
7795 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
7796 generated sections, consequently added Makefile headers with inheritance
7797 information, added subdir movement messages for easier following where
7798 the build process currently stays (more verbose then standard Make, less
7799 verbose than GNU make), same style to comments in the Configure script,
7800 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
7802 *) Add the new ApacheBench program "ab" to src/support/: This is derived
7803 from the ZeusBench benchmarking program and can be used to determine the
7804 response performance of an Apache installation. This version is
7805 officially licensed with Zeus Technology, Ltd. See the license agreement
7806 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
7807 [Ralf S. Engelschall]
7809 *) API: Various core functions that are definately not part of the API
7810 have been made static, and a few have been marked API_EXPORT. Still
7811 more have been marked CORE_EXPORT and are not intended for general
7812 use by modules. [Doug MacEachern, Dean Gaudet]
7814 *) mod_proxy was not clearing the Proxy-Connection header from
7815 requests; now it does. This did not violate any spec, however
7816 causes poor interactions when you are talking to remote proxies.
7817 [Marc Slemko] PR#1741
7819 *) Various cleanups to the command line interface and manual pages.
7820 [Ralf S. Engelschall]
7822 *) cfg_getline() was not properly handling lines that did not end
7823 with a line termination character. [Marc Slemko] PR#1869, 1909
7825 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
7827 *) Clean up some undocumented behavior of mod_setenvif related to
7828 "merging" two SetEnvIf directives when they match the same header
7829 and regex. Document that mod_setenvif will perform comparisons in
7830 the order they appear in the config file. Optimize mod_setenvif by
7831 doing more work at config time rather than at runtime.
7834 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
7835 to allow for modules to overrule them and to reduce redefinition
7836 warnings [Jim Jagielski]
7838 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
7841 *) Making the hard-coded cross-module function call mime_find_ct() (from
7842 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
7843 checking is really called even for proxy requests except for URLs with
7844 HTTP schemes (because there we can optimize by not running the type
7845 checking hooks due to the fact that the proxy gets the MIME Content-type
7846 from the remote host later). This change cleans up mod_mime by removing
7847 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
7848 especially unbundles mod_proxy and mod_mime. This way they both now can
7849 be compiled as shared objects and are no longer tied together.
7850 [Ralf S. Engelschall]
7852 *) util.c cleanup and speedup. [Dean Gaudet]
7854 *) API: Clarification, pstrndup() will always copy n bytes of the source
7855 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
7857 *) Mark module command_rec and handler_rec structures const so that they
7858 end up in the read-only data section (and are friendlier to systems
7859 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
7861 *) Add check to the "Port" directive to make sure the specified
7862 port is in the appropriate range. [Ben Hyde]
7864 *) Performance improvements to invoke_handler().
7865 [Dmitry Khrustalev <dima@bog.msu.su>]
7867 *) Added support for building shared objects even for library-style modules
7868 (which are built from more than one object file). This now provides the
7869 ability to build mod_proxy as a shared object module. Additionally
7870 modules like mod_example are now also supported for shared object
7871 building because the generated Makefiles now no longer assume there is at
7872 least one statically linked module. [Ralf S. Engelschall]
7874 *) API: Clarify usage of content_type, handler, content_encoding,
7875 content_language and content_languages fields in request_rec. They
7876 must always be lowercased; and the strings pointed to shouldn't
7877 be modified (you must copy them to modify them). Fix a few bugs
7878 related to this. [Dean Gaudet]
7880 *) API: Clarification: except for RAW_ARGS, all command handlers can
7881 treat the char * parameters as permanent, and modifiable. There
7882 is no need to pstrdup() them. Clean up some needless pstrdup().
7885 *) Now mod_so keeps track of which module shared objects with which names
7886 are loaded and thus avoids multiple loading and unloading and irritating
7887 error_log messages. [Ralf S. Engelschall]
7889 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
7890 environment variable in the apache core. But that tweaking interferes
7891 with mod_setenv. So don't tweak if the user has specified an explicit
7892 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
7894 *) rputs() did not calculate r->sent_bodyct properly.
7895 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
7897 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
7898 name, or left unset if this value is unavailable. Apache was setting
7899 it to the IP address when unavailable.
7900 [Tony Finch <fanf@demon.net>] PR#1925
7902 *) Various improvements to the configuration and build support for compiling
7903 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
7904 OSF1 support with GCC and vendor compilers was added. This way shared
7905 object support is now provided out-of-the-box for FreeBSD, Linux,
7906 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
7907 [Ralf S. Engelschall]
7909 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
7910 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
7911 and USE_OS2_SCOREBOARD. [Dean Gaudet]
7913 *) Fix one more special locking problem for RewriteMap programs in
7914 mod_rewrite: According to the documentation of flock(), "Locks are on
7915 files, not file descriptors. That is, file descriptors duplicated
7916 through dup(2) or fork(2) do not result in multiple instances of a lock,
7917 but rather multiple references to a single lock. If a process holding a
7918 lock on a file forks and the child explicitly unlocks the file, the
7919 parent will lose its lock.". To overcome this we have to make sure the
7920 RewriteLock file is opened _AFTER_ the childs were spawned which is now
7921 the case by opening it in the child_init instead of the module_init API
7922 hook. [Ralf S. Engelschall] PR#1029
7924 *) Change to Location and LocationMatch semantics. LocationMatch no
7925 longer lets a single slash match multiple adjacent slashes in the
7926 URL. This change is for consistency with RewriteRule and
7927 AliasMatch. Multiple slashes have meaning in URLs that they do
7928 not have in (some) filesystems. Location on the other hand can
7929 be considered a shorthand for a more complicated regex, and it
7930 does match multiple slashes with a single slash -- which is
7931 also consistent with the Alias directive.
7932 [Dean Gaudet] related PR#1440
7934 *) Fix bug with mod_mime_magic causing certain files, including files
7935 of length 0, to result in no response from the server.
7938 *) The Configure script now generates src/include/ap_config.h which
7939 contains the set of defines used when Apache is compiled on a platform.
7940 This file can then be included by external modules before including
7941 any Apache header files in case they are being built separately from
7942 Apache. Along with this change, a couple of minor changes were
7943 made to make Apache's #defines coexist peacefully with any autoconf
7944 defines an external module might have. [Rasmus Lerdorf]
7946 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
7947 but without any RewriteXXXXX directives. Here mod_rewrite is given no
7948 chance by the API to initialize its per-server configuration and thus
7949 receives the wrong one from the main server. This is now avoided by
7950 remembering the server together with the config structure while
7951 configuring and later assuming there is no config when we see a
7952 difference between the remembered server and the one calling us.
7953 [Ralf S. Engelschall] PR#1790
7955 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
7956 is automatically disabled under configure time when the dbm_xxx functions
7957 are not available. Second, two heavy source code errors in the DBM
7958 support code were fixed. This makes DBM RewriteMap's usable again after
7959 a long time of brokenness. [Ralf S. Engelschall] PR#1696
7961 *) Now all configuration files support Unix-style line-continuation via
7962 the trailing backslash ("\") character. This enables us to write down
7963 complex or just very long directives in a more readable way. The
7964 backslash character has to be really the last character before the
7965 newline and it has not been prefixed by another (escaping) backslash.

7978 in PATH_INFO). [Paul Sutton, Ben Laurie]
7980 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
7981 depending on the rev of Solaris and what mixture of modules
7982 are in use. So it has been disabled, and Solaris is back to
7983 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
7984 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
7985 up static content only servers. Or it may fail unpredictably.

7988 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
7991 *) API: Rewrite of absoluteURI handling, and in particular how
7992 absoluteURIs match vhosts. Unless a request is a proxy request, a
7993 "http://host" url is treated as if a similar "Host:" header had been
7994 supplied. This change was made to support future HTTP/1.x protocols
7995 which may require clients to send absoluteURIs for all requests.
7997 In order to achieve this change subtle changes were made to the API. In a
7998 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
7999 that the unmodified uri can be retrieved easily. r->proxyreq is not set
8000 by the core, modules must set it during the post_read_request or
8001 translate_names phase.
8003 Plus changes to the virtualhost test suite for absoluteURI testing.
8005 This fixes several bugs with the proxy proxying requests to vhosts
8006 managed by the same httpd.

8027 *) API: A new source module main/util_uri.c; It contains a routine
8028 parse_uri_components() and friends which breaks a URI into its component
8029 parts. These parts are stored in a uri_components structure called
8030 parsed_uri within each request_rec, and are available to all modules.
8031 Additionally, an unparse routine is supplied which re-assembles the URI
8032 components back to an URI, optionally hiding the username:password@ part
8033 from ftp proxy requests, and other useful routines. Within the structure,
8034 you find on a ready-for-use basis:
8035 scheme; /* scheme ("http"/"ftp"/...) */
8036 hostinfo; /* combined [user[:password]@]host[:port] */
8037 user; /* user name, as in http://user:passwd@host:port/ */
8038 password; /* password, as in http://user:passwd@host:port/ */
8039 hostname; /* hostname from URI (or from Host: header) */
8040 port_str; /* port string (integer representation is in "port") */
8041 path; /* the request path (or "/" if only scheme://host was given) */
8042 query; /* Everything after a '?' in the path, if present */
8043 fragment; /* Trailing "#fragment" string, if present */
8044 This is meant to serve as the platform for *BIG* savings in
8045 code complexity for the proxy module (and maybe the vhost logic).
8048 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
8049 ${map:key}) available for all location where a string is created in

8093 functionality needed for balancing between backend-servers when using
8094 Apache as a Reverse Proxy. The looked up value here is a list of
8095 servers). Second, `int' with the built-in maps named `tolower' and
8096 `toupper' which can be used to map URL parts to a fixed case (this is an
8097 essential feature to fix the case of server names when doing mass
8098 virtual-hosting with the help of mod_rewrite instead of using
8099 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
8100 Jay Soffian <jay@cimedia.com>] PR#1631
8102 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
8103 This directive lets Apache adjust the URL in Location-headers on HTTP
8104 redirect responses sent by the remote server. This way the virtually
8105 mapped area is no longer left on redirects and thus by-passed which is
8106 especially essential when running Apache as a reverse proxy.

8109 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
8110 hidden. [Alvaro Martinez Echevarria]
8112 *) Apache will, when started with the -X (single process) debugging flag,
8113 honor the SIGINT or SIGQUIT signals again now. This capability got lost
8114 a while ago during OS/2 signal handling changes.

8124 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
8125 In particular the handlers could trigger themselves into an infinite
8126 loop if RLimitMem was used with a small amount of memory -- too small
8127 for the signal stack frame to be set up. [Dean Gaudet]

8141 *) mod_info would occasionally produce an unpaired <tt> in its
8142 output. Fixed. [Martin Kraemer]
8144 *) By default AIX binds a process (and it's children) to a single
8145 processor. httpd children now unbind themselves from that cpu
8146 and re-bind to one selected at random via bindprocessor()
8149 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
8150 effect. Work around it by using RLIMIT_AS for the RLimitMEM
8151 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
8153 *) mod_mime_magic error message should indicate the filename when
8154 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
8156 *) Previously Apache would permit </Files> to end <FilesMatch> (and
8157 similary for Location and Directory), now this is diagnosed as an
8158 error. Improve error messages for mismatched sections (<Files>,
8159 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).

8162 *) <Files> is not permitted within <Location> (because of the
8163 semantic ordering). [Dean Gaudet] PR#379

8176 *) Various errors from select() and accept() in child_main() would
8177 result in an infinite loop. It seems these two tickle kernel

8204 *) Sort out problems with canonical filename handling happening too late.
8205 [Dean Gaudet, Ben Laurie]
8207 Changes with Apache 1.3b4
8209 *) The module structure was modified to include a *dynamic_load_handle
8210 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
8211 has been bumped accordingly. [Paul Sutton]
8213 *) All BrowserMatch directives mentioned in
8214 htdocs/manual/known_client_problems.html are in the default
8215 configuration files. [Lars Eilebrecht]
8217 *) MiNT port update. [Jan Paul Schmidt]
8219 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
8220 equivalent, similarly for x-compress and compress. Apache
8221 now ignores a leading x- when comparing encodings. It also
8222 preserves the encoding the client requests (for example if
8223 it requests x-gzip, then Apache will respond with x-gzip
8224 in the Content-Encoding header).
8225 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
8227 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
8229 *) Added mod_so module to support dynamic loading of modules on Unix
8230 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
8231 instead of AddModule in Configuration to build shared modules
8232 [Sameer Parekh, Paul Sutton]
8234 *) Minor cleanups to r->finfo handling in some modules.
8237 *) Abstract read()/write() to ap_read()/ap_write().
8238 Makes it easier to add other types of IO code such as SFIO.
8241 *) API: Generalize default_port manipulations to make support of
8242 different protocols easier. [Ben Laurie, Randy Terbush]
8244 *) There are many cases where users do not want Apache to form
8245 self-referential urls using the "canonical" ServerName and Port.
8246 The new UseCanonicalName directive (default on), if set to off
8247 will cause Apache to use the client-supplied hostname and port.
8248 API: Part of this change required a change to the construct_url()
8249 prototype; and the addition of get_server_name() and
8251 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
8252 PR#315, 459, 485, 1433
8254 *) Yet another rearrangement of the source tree.. now all the common
8255 header files are in the src/include directory. The -Imain -Iap
8256 references in Makefiles have been changed to the simpler -Iinclude
8257 instead. In addition to simplifying the build a little bit, this
8258 also makes it clear when a module is referencing something in a
8259 other than kosher manner (e.g., the proxy including mod_mime.h).
8260 Module-private header files (the proxy, mod_mime, the regex library,
8261 and mod_rewrite) have not been moved to src/include; nor have
8262 the OS-abstraction files. [Ken Coar]
8264 *) Fix a bug where r->hostname didn't have the :port stripped
8265 from it. [Dean Gaudet]
8267 *) Tweaked the headers_out table size, and the subprocess_env
8268 table size guess in rename_original_environment(). Added
8269 MAKE_TABLE_PROFILE which can help discover make_table()
8270 calls that use too small an initial guess, see alloc.c.
8273 *) Options and AllowOverride weren't properly merging in the main
8274 server setting inside vhosts (only an issue when you have no
8275 <Directory> or other section containing an Options that affects
8276 a request). Options +foo or -foo in the main_server wouldn't
8277 affect the main_server's lookup defaults. [Dean Gaudet]
8279 *) Variable 'cwd' was being used pointlessly before being set.
8282 *) r->allowed handling cleaned up in the standard modules.
8285 *) Some case-sensitivity issues cleaned up to be consistent with
8286 RFC2068. [Dean Gaudet]
8288 *) SIGURG doesn't exist everywhere.
8289 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8291 *) mod_unique_id was erroneously generating a second unique id when
8292 an internal redirect occured. Such redirects occur, for example,
8293 when processing a DirectoryIndex match. [Dean Gaudet]
8295 *) API: table_add, table_merge, and table_set include implicit pstrdup()
8296 of the key and value. But in many cases this is not required
8297 because the key/value is a constant, or the value has been built
8298 by pstrcat() or other similar means. New routines table_addn,
8299 table_mergen, and table_setn have been added to the API, these
8300 routines do not pstrdup() their arguments. The core code and
8301 standard modules were changed to take advantage of these routines.
8302 The resulting server is up to 20% faster in some situations.
8304 Note that it is easy to get code subtly wrong if you pass a key/value
8305 which is in a pool other than the pool of the table. The only
8306 safe thing to do is to pass key/values which are in the pool of
8307 the table, or in one of the ancestors of the pool of the table.
8308 i.e. if the table is part of a subrequest, a value from the main
8309 request's pool is OK since the subrequest pool is a sub_pool of the
8310 main request's pool (and therefore has a lifespan at most as long as
8311 the main pool). There is debugging code which can detect improper
8312 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
8313 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
8315 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
8316 which don't exist on disk more gracefully; handles vhosts properly.
8317 Update documentation to reflect the code -- if there's no
8318 MimeMagicFile directive then the module is not enabled.
8321 *) PORT: Some older *nix dialects cannot automatically start scripts
8322 which begin with a #! interpreter line (the shell starts the scripts
8323 appropriately on these platforms). Apache now supports starting of
8324 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
8325 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
8328 *) API: "typedef array_header table" removed from alloc.h, folks should
8329 have been writing to use table as if it were an opaque type, but even
8330 some standard modules got this wrong. By changing the definition
8331 to "typedef struct table table" module authors will receive compile
8332 time warnings that they're doing the wrong thing. This change
8333 facilitates future changes with more sophisticated table
8334 structures. Specifically, module authors should be using table_elts()
8335 to get access to an array_header * for the table. [Dean Gaudet]
8337 *) API: Renamed new_connection() to avoid namespace collision with LDAP
8338 library routines. [Ken Coar, Rasmus Lerdorf]
8340 *) WIN32: mod_speling is now available on the Win32 platform.
8343 *) For clarity the following compile time definition was changed:
8345 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
8347 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
8348 and not be a general notice that the OS has mmap(). Now the
8349 HAVE_MMAP/SHMGET #defines strictly are informational that the
8350 OS has that method of shared memory; the type to use for
8351 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
8352 and USE_SHMGET_SCOREBOARD). This allows outside modules to
8353 determine if shared memory is available and allows Apache
8354 to determine the best method to use for the scoreboard.
8357 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
8358 as do various earlier versions. It should be safe on all versions.
8359 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
8360 the slack code. A few other cleanups for Unixware.

8363 *) PORT: A/UX can handle single-listen accepts without mutex
8364 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
8366 *) When die() happens we need to eat any request body if one exists.
8367 Otherwise we can't continue with a keepalive session. This shows up
8368 as a POST problem with MSIE 4.0, typically against pages which are
8369 authenticated. [Roy Fielding] PR#1399
8371 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
8372 header will be passed to CGIs. This is generally a security hole, so
8373 it's not a default. [Marc Slemko] PR#549
8375 *) Fix Y2K problem with date printing in suexec log.

8378 *) WIN32 deserves a pid file. [Ben Hyde]
8380 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
8382 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
8383 The choice of flock vs. fcntl was made based on timings which showed that
8384 even on non-NFS, non-exported filesystems fcntl() was an order of
8385 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
8386 that single socket users will see no difference. [Dean Gaudet] PR#467
8388 *) "File does not exist" error message was erroneously including the
8389 errno. [Marc Slemko]
8391 *) Improve the warning message generated when a client drops the
8392 connection (hits stop button, etc.) during a send. [Roy Fielding]
8394 *) Defining GPROF will disable profiling in the parent and enable it
8395 in the children. If you're profiling under Linux this is pretty much
8396 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
8398 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
8401 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
8402 gcc functionality. Work around it.

8405 *) Some linkers complain when .o files contain no functions.
8406 [Keith Severson <keith@sssd.navy.mil>] PR#1614
8408 *) Some const declarations in mod_imap.c that were added for debugging
8409 purposes caused some compilers heartburn without adding any
8410 significant value, so they've been removed. [Ken Coar]
8412 *) The src/main/*.h header files have had #ifndef wrappers added to
8413 insulate them against duplicate calls if they get included through
8414 multiple paths (e.g., in .c files as well as other .h files).
8417 *) The libap routines now have a header file for their prototypes,
8418 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
8420 *) mod_autoindex with a plaintext header file would emit the <PRE>
8421 start-tag before the HTML preamble, rather than after the preamble
8422 but before the header file contents. [John Van Essen <jve@gamers.org>]
8425 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8426 only an issue on systems without a MAXDNAME define or where
8427 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8429 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8430 is used to read various types of files such as htaccess and
8431 htpasswd files. [Marc Slemko]
8433 *) SECURITY: Ensure that the buffer returned by ht_time is always
8434 properly null terminated. [Marc Slemko]
8436 *) The "Connection" header could be sent back with multiple "close"
8437 tokens. Not an error, but a waste.
8438 [Ronald.Tschalaer@psi.ch] PR#1683
8440 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
8441 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
8443 *) "basic" auth needs a case-insensitive comparison.
8444 [Ronald.Tschalaer@psi.ch] PR#1666
8446 *) For maximum portability, the environment passed to CGIs should
8447 only contain variables whose names match the regex
8448 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
8449 underscores over any character outside the regex. This
8450 affects HTTP_* variables, in a way that should be backward
8451 compatible for all the standard headers; and affects variables
8452 set with SetEnv/BrowserMatch and similar directives.
8455 *) mod_speling returned incorrect HREF's when an ambigous match
8456 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
8457 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
8459 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
8460 (the Siemens BS2000/OSD family) in the POSIX subsystem
8463 *) PORT: Fix problem killing children when terminating. Allow ^C
8464 to shut down the server. [Brian Havard]
8466 *) pstrdup() is implicit in calls to table_* functions, so there's
8467 no need to do it before calling. Clean up a few cases.
8468 [Marc Slemko, Dean Gaudet]
8470 *) new -C and -c command line arguments

8488 possible buffer overflows and a possible infinite loop.
8489 [Dean Gaudet, Marc Slemko]
8491 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8492 including fixing a possible buffer overflow. [Dean Gaudet]
8494 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
8495 (connections are not dropped). Code can handle graceful restarts
8496 (but there is as yet no way to signal this to Apache). Various
8497 other cleanups. [Paul Sutton]
8499 *) The aplog_error changes specific to 1.3 introduced a buffer
8500 overrun in the (now legacy) log_printf function. Fixed.
8503 *) mod_digest didn't properly deal with proxy authentication. It
8504 also lacked a case-insensitive comparision of the "Digest"
8505 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
8507 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]

8534 alloc.c (affects win32 only). [Ben Hyde]
8536 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
8538 *) send_fd_length() did not calculate total_bytes_sent properly.
8539 [Ben Reser <breser@regnow.com>] PR#1366
8541 *) The bputc() macro was not properly integrated with the chunking
8542 code; in many cases modules using bputc() could cause completely
8543 bogus chunked output. (Typically this will show up as problems
8544 with Internet Explorer 4.0 reading a page, but other browsers
8545 having no problem.) [Dean Gaudet]
8547 *) Create LARGE_WRITE_THRESHOLD define which determines how many
8548 bytes have to be supplied to bwrite() before it will consider
8549 doing a writev() to assemble multiple buffers in one system
8550 call. This is critical for modules such as mod_include,
8551 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
8552 strings in some cases. The result would be extra effort
8553 setting up writev(), and in many cases extra effort building
8554 chunks. The default is 31, it can be overriden at compile
8557 *) Move the gid switching code into the child so that log files

8570 the libap consolidation work. [Ken Coar]

8622 *) proxy_ftp: the directory listings generated by the proxy ftp module
8623 now have a title in which the path components are clickable and allow
8624 quick navigation to the clicked-on directory on the currently listed
8625 ftp server. This also fixes a bug where the ".." directory links would
8626 sometimes refer to the wrong directory. [Martin Kraemer]
8628 *) WIN32: Allocate the correct amount of memory for the scoreboard.
8631 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]
8634 *) Fix problems with timeouts in inetd mode and -X mode. [Dean Gaudet]
8636 *) Fix the spurious "(0)unknown error: mmap_handler: mmap failed"
8637 error messages. [Ben Hyde]
8639 Changes with Apache 1.3b3
8641 *) WIN32: Work around brain-damaged spawn calls that can't deal
8642 with spaces and slashes. [Ben Laurie]
8644 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
8645 The problem was that certain undocumented environment variables
8646 needed for sockets to work under Win32 were not being passed.
8647 [Frank Faubert <frank@sane.com>]
8649 *) Add a "-V" command line flag to the httpd binary. This
8650 flag shows some of the defines that Apache was compiled with.
8651 It is useful for debugging purposes. [Martin Kraemer]
8653 *) Start separating the ap_*() routines into their own library, so they
8654 can be used by items in src/support among other things.
8655 [Ken Coar] PR#512, 905, 1252, 1308
8657 *) Give a more informative error when no AuthType is set.
8660 *) Remove strtoul() use from mod_proxy because it isn't available
8661 on all platforms. [Marc Slemko] PR#1214
8663 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
8664 This turns out to be a bug in Winsock - select() doesn't always
8665 return the correct status. [Ben Laurie]
8667 *) Directives owned by http_core can now use the new check_cmd_context()
8668 routine to ensure that they're not being used within a container
8669 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
8671 *) PORT: Recent changes made it necessary to add explicit prototype
8672 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
8674 *) It was necessary to distinguish between resources which are
8675 allocated in the parent, for cleanup in the parent, and resources
8676 which are allocated in each child, for cleanup in each child.
8677 A new pool was created which is passed to the module child_init
8678 and child_exit functions; modules are free to register per-child
8679 cleanups there. This fixes a bug with reliable piped logs.
8682 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
8683 unless it was also doing FancyIndexes, but it displayed the
8684 HeaderName file at the top under all circumstances. It now shows
8685 the ReadmeName file for simple indices, too, as it should.
8688 *) http_core was mmap()ing even in cases where it wasn't going to
8689 read the file. [Ben Hyde <bhyde@gensym.com>]
8691 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
8692 Now the rewriting engine (the heart of mod_rewrite) is organized more
8693 straight-forward, first time well documented and reduced to the really
8694 essential parts. All redundant cases were stripped off and processing now
8695 is the same for both per-server and per-directory context with only a
8696 minimum difference (the prefix stripping in per-dir context). As a
8697 side-effect some subtle restrictions and two recently discovered problems
8698 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
8699 context and restrictions on the substitution URL on redirects.
8700 Additionally some minor source cleanups were done.

8704 documentation, examples, explanations and caveats. They live in a new

8707 *) If ap_slack fails to allocate above the low slack line it's a good
8708 indication that further problems will occur; it's a better indication
8709 than many external libraries give us when we actually run out of
8710 descriptors. So report it to the user once per restart.

8851 splits up a combined access log into separate files based on the
8852 name of the virtual host (listed first in the log records by "%v").
8855 Changes with Apache 1.3b2 (there is no 1.3b1)
8857 *) TestCompile was not passing $LIBS [Dean Gaudet]
8859 *) Makefile.tmpl was not using $CFLAGS in the link phase.
8862 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
8863 rudimentary memory debugger which can be used on live servers with
8864 low impact -- it sets all allocated and freed memory bytes to 0xa5.
8865 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
8866 and free() for each object. This is far more expensive and should
8867 only be used for testing with tools such as Electric Fence and
8868 Purify. See main/alloc.c for more details. [Dean Gaudet]
8870 *) Configure uses a sh trap and didn't set its exitcode properly.
8871 [Dean Gaudet] PR#1159
8873 *) Yet another vhost revamp. Add the NameVirtualHost directive which
8874 explicitly lists the ip:port pairs that are to be used for name-vhosts.
8875 From a given ip:port, regardless what the Host: header is, you can
8876 only reach the vhosts defined on that ip:port. The precedence of
8877 vhosts was reversed to match other precedences in the config --
8878 the earlier vhosts override the later vhosts. All vhost matching was
8879 moved into http_vhost.[ch]. [Dean Gaudet]
8881 *) ap_inline can be used to force inlining. GNUC __attribute__() can
8882 be used for whatever reason is appropriate (i.e. format() warnings
8883 for printf style functions). Both are enabled only with
8884 gcc >= 2.7.x (so that we have fewer support issues with older
8885 versions). [Dean Gaudet]
8887 *) Fix support for Proxy Authentication (we were testing the response
8888 status too early). [Marc Slemko]
8890 *) CoreDumpDirectory directive directs where the core file is
8891 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
8892 received. [Marc Slemko, Dean Gaudet]
8894 *) PORT: Support for Atari MINT.
8895 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
8897 *) When booting, apache will now detach itself from stdin, stdout,
8898 and stderr. stderr will not be detached until after the config
8899 files have been read so you will be able to see initial error
8900 messages. After that all errors are logged in the error_log.
8901 This makes it more convenient to start apache via rsh, ssh,
8902 or crontabs. [Dean Gaudet] PR#523
8904 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8905 Also removed the auto-generated link to www.apache.org that was the
8906 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8908 *) send_fb would not detect aborted connections in some situations.
8911 *) mod_include would use uninitialized data when parsing certain
8912 expressions involving && and ||. [Brian Slesinsky] PR#1139
8914 *) mod_imap should only handle GET methods. [Jay Bloodworth]
8916 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8918 *) mod_autoindex improperly counted &escapes; as more than one
8919 character in the description. It also improperly truncated
8920 descriptions that were exactly the maximum length.
8923 *) RedirectMatch was not properly escaping the result (PR#1155). Also
8924 "RedirectMatch /advertiser/(.*) $1" is now permitted.
8927 *) mod_include now uses symbolic names to check for request success
8928 and return HTTP errors, and correctly handles all types of
8929 redirections (previously it only did temporary redirect correctly).
8930 [Ken Coar, Roy Fielding]
8932 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8933 r->filename. Since those two are meant to be in sync with each other
8934 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
8936 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
8937 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
8939 *) Inetd mode (which is buggy) uses timeouts without having setup the
8940 jmpbuffer. [Dean Gaudet] PR#1064
8942 *) Work around problem under Linux where a child will start looping
8943 reporting a select error over and over.
8944 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
8946 *) Fixed error in proxy_util.c when looping through multiple host IP
8947 addresses. [Lars Eilebrecht] PR#974
8949 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
8950 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
8951 bytes before writing, but it will never split a log entry across a
8952 buffer boundary. [Dean Gaudet]
8954 *) API: the short_score record has been split into two pieces, one which
8955 the parent writes on, and one which the child writes on. As part of
8956 this change the get_scoreboard_info() function was removed, and
8957 scoreboard_image was exported. This change fixes a race condition
8958 in file based scoreboard systems, and speeds up changes involving the
8959 scoreboard in earlier 1.3 development. [Dean Gaudet]
8961 *) API: New register_other_child() API (see http_main.h) which allows
8962 modules to register children with the parent for maintenance. It
8963 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
8965 *) API: New piped_log API (see http_log.h) which implements piped logs,
8966 and will use register_other_child to implement reliable piped logs
8967 when it is available. The reliable piped logs part can be disabled
8968 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
8969 logs is only available on Unix. [Dean Gaudet]
8971 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
8972 meets_conditions(). This allows conditional HTTP selection to be
8973 handled separately from the storing of the header fields, and provides
8974 the ability for CGIs to set their own ETags for conditional checking.
8975 [Ken Coar, Roy Fielding] PR#895
8977 *) Changes to mod_log_config to allow naming of format strings.
8978 Format nicknames are defined with "LogFormat fmt nickname", and can
8979 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
8982 *) New module, "mod_speling", which can help find files even when
8983 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
8985 *) API: New function child_terminate() triggers the child process to
8986 exit, while allowing the child finish what it needs to for the
8987 current request first.
8988 [Doug MacEachern, Alexei Kosut]
8990 *) Windows now defaults to using full status reports with mod_status.
8991 [Alexei Kosut] PR #1094
8993 *) *Really* disable all mod_rewrite operations if the engine is off.
8994 Some things (like RewriteMaps) were checked/performed even if they
8995 weren't supposed to be. [Ken Coar] PR #991
8997 *) Implement a new timer scheme which eliminates the need to call alarm() all
8998 the time. Instead a counter in the scoreboard for each child is used to
8999 show when the child has made forward progress. The parent samples this
9000 counter every scoreboard maintenance cycle, and issues SIGALRM if no
9001 progress has been made in the timeout period. This reduces the static
9002 request best-case syscall count to 22 from 29. This scheme is only
9003 used by systems with memory-based scoreboards. [Dean Gaudet]
9005 *) The proxy now properly handles CONNECT requests which are sent
9006 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
9008 *) A script called apachectl has been added to the support
9009 directory. This script allows you to do things such as
9010 "apachectl start" and "apachectl restart" from the command
9013 *) Modules and core routines are now put into libraries, which
9014 simplifies the link line tremendously (among other advantages).
9017 *) Some of the MD5 names defined in Apache have been renamed to have
9018 an `ap_' prefix to avoid conflicts with routines supplied by
9019 external libraries. [Ken Coar]
9021 *) Removal of mod_auth_msql.c from the distribution. There are many
9022 other options for databases today. Rather than offer one option,
9023 offer none at this time. mod_auth_msql and other SQL database
9024 authentication modules can be found at the Apache Module Registry.
9025 http://modules.apache.org/ It would be nice to offer a generic
9026 mod_auth_sql option in the near future.
9028 *) PORT: BeOS support added [Alexei Kosut]
9030 *) Configure no longer accepts the -make option, since it creates
9031 Makefile on the fly based on Makefile.tmpl and Configuration.
9033 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
9034 of forcibly killing off all its processes and exiting without
9035 cleaning up. [Alexei Kosut]
9037 *) API: A new field in the request_rec, r->mtime, has been added to
9038 avoid gratuitous parsing of date strings. It is intended to hold
9039 the last-modified date of the resource (if applicable). An
9040 update_mtime() routine has also been added to advance it if
9041 appropriate. [Roy Fielding, Ken Coar]
9043 *) SECURITY: If a htaccess file can not be read due to bad permissions,
9044 deny access to the directory with a HTTP_FORBIDDEN. The previous
9045 behavior was to ignore the htaccess file if it could not be read.
9046 This change may make some setups with unreadable htaccess files
9047 stop working. [Marc Slemko] PR#817
9049 *) Add aplog_error() providing a mechanism to define levels of
9050 verbosity to the server error logging. This addition also provides
9051 the ability to log errors using syslogd. Error logging is configurable
9052 on a per-server basis using the LogLevel directive. Conversion
9053 of log_*() in progress. [Randy Terbush]
9055 *) Further enhance aplog_error() to not log filename, line number, and
9056 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
9058 *) WIN32: Canonicalise filenames under Win32. Short filenames are
9059 converted to long ones. Backslashes are converted to forward
9060 slashes. Case is converted to lower. Parts of URLs that do not
9061 correspond to files are left completely alone. [Ben Laurie]
9063 *) PORT: 2 new OSs added to the list of ports:
9064 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
9065 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
9067 *) Add the server version (SERVER_VERSION macro) to the "server
9068 configured and running" entry in the error_log. Also build an
9069 object file at link-time that contains the current time
9070 (SERVER_BUILT global const char[]), and include that in the
9073 *) Set r->headers_out when sending responses from the proxy.
9074 This fixes things such as the logging of headers sent from
9075 the proxy. [Marc Slemko] PR#659
9077 *) support/httpd_monitor is no longer distributed because the
9078 scoreboard should not be file based if at all possible. Use
9079 mod_status to see current server snapshot.
9081 *) (set_file_slot): New function, allowing auth directives to be
9082 independent of the server root, so the server documents can be
9083 moved to a different directory or machine more easily.
9084 [David J. MacKenzie]
9086 *) If no TransferLog is given explicitly, decline
9087 to log. This supports coexistence with other logging modules,
9088 such as the custom one that UUNET uses. [David J. MacKenzie]
9090 *) Check for titles in server-parsed HTML files.
9091 Ignore leading newlines and returns in titles. The old behavior
9092 of replacing a newline after <title> with a space causes the
9093 title to be misaligned in the listing. [David J. MacKenzie]
9095 *) Change mod_cern_meta to be configurable on a per-directory basis.
9096 [David J. MacKenzie]
9098 *) Add 'Include' directive to allow inclusion of configuration
9099 files within configuration files. [Randy Terbush]
9101 *) Proxy errors on connect() are logged to the error_log (nothing
9102 new); now they include the IP address and port that failed
9103 (*that's* new). [Ken Coar, Marc Slemko] PR#352
9105 *) Various architectures now define USE_MMAP_FILES which causes
9106 the server to use mmap() for static files. There are two
9107 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
9108 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
9109 number of bytes written in one cycle from a single mmap()d object,
9110 default 32768). [Dean Gaudet]
9112 *) API: Added post_read_request API phase which is run right after reading
9113 the request from a client, or right after an internal redirect. It is
9114 useful for modules setting environment variables that depend only on
9115 the headers/contents of the request. It does not run during subrequests
9116 because subrequests inherit pretty much everything from the main
9117 request. [Dean Gaudet]
9119 *) Added mod_unique_id which is used to generate a unique identifier for
9120 each hit, available in the environment variable UNIQUE_ID.
9123 *) init_modules is now called after the error logs have been opened. This
9124 allows modules to emit information messages into the error logs.
9127 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9128 information for case where proxy module is not available. [Marc Slemko]
9130 *) PORT: Apache has need for mutexes to serialize its children around
9131 accept. In prior versions either fcntl file locking or flock file
9132 locking were used. The method is chosen by the definition of
9133 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
9134 and FLOCK for flock(). New options have been added:
9135 - SYSVSEM to use System V style semaphores
9136 - PTHREAD to use POSIX threads (appears to work on Solaris only)
9137 - USLOCK to use IRIX uslock
9138 Based on timing various techniques, the following changes were made
9140 - Linux 2.x uses flock instead of fcntl
9141 - Solaris 2.x uses pthreads
9142 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
9143 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
9144 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
9145 Martijn Koster <m.koster@pobox.com>]
9147 *) PORT: The semantics of accept/select make it very desirable to use
9148 mutexes to serialize accept when multiple Listens are in use. But
9149 in the case where only a single socket is open it is sometimes
9150 redundant to serialize accept(). Not all unixes do a good job with
9151 potentially dozens of children blocked on accept() on the same
9152 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
9153 the server will avoid serialization when listening on only one socket,
9154 and use serialization when listening on multiple sockets.
9155 [Dean Gaudet] PR#467
9157 *) Configure changes: TestLib replaced by TestCompile, which has
9158 some additional capability (such as doing a sanity check of
9159 the compiler and flags selected); the version of Solaris is now
9160 available via the #define value of SOLARIS2; IRIX n32bit libs
9161 now supported and selectable by new Configuration Rule: IRIXN32;
9162 We no longer default to -O2 optimization. [Jim Jagielski]
9164 *) Updated Configure: Configuration now uses AddModule to specify
9165 module source or binary file location, relative to src directory.
9166 Modules can be dropped into modules/extra, or in their own
9167 directory, and modules can come with a Makefile or Configure can
9168 create one. Modules can add compiler or library information to
9169 generated Makefiles. [Paul Sutton]
9171 *) Source core re-organisation: distributed modules are now in
9172 modules/standard. All other source code is in main. OS-specific
9173 code is in os/{unix,emx,win32} directories. [Paul Sutton]
9175 *) mod_browser has been removed, since it's replaced by mod_setenvif.
9178 *) Fix another long-standing bug in sub_req_lookup_file where it would
9179 happily skip past access checks on subdirectories looked up with
9180 relative paths. (It's used by mod_dir, mod_negotiation,
9181 and mod_include.) [Dean Gaudet]
9183 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
9184 N is the number of <Directory> sections, and M is the number of
9185 components in the filename of an object.
9187 To achieve this optimization the following config changes were made:
9188 - Wildcards (* and ?, not the regex forms) in <Directory>s,
9189 <Files>s, and <Location>s now treat a slash as a special
9190 character. For example "/home/*/public_html" previously would
9191 match "/home/a/andrew/public_html", now it only matches things
9192 like "/home/bob/public_html". This mimics /bin/sh behaviour.
9193 - It's possible now to use [] wildcarding in <Directory>, <Files>
9195 - Regex <Directory>s are applied after all non-regex <Directory>s.
9199 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
9200 and corrupted paths. [Dean Gaudet]
9202 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
9203 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
9204 be accessed now via backreferences $1..$9 in RewriteConds test-against
9205 strings in addition to RewriteRules subst string. Second the grouped
9206 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
9207 via backreferences %1..%9 both in following RewriteCond test-against
9208 strings and RewriteRules subst string. This provides maximum flexibility
9209 through the use of backreferences.
9210 Additionally the rewriting engine was cleaned up by putting common
9211 code to the new expand_backrefs_inbuffer() function.
9212 [Ralf S. Engelschall]
9214 *) When merging the main server's <Directory> and <Location> sections into
9215 a vhost, put the main server's first and the vhost's second. Otherwise
9216 the vhost can't override the main server. [Dean Gaudet] PR#717
9218 *) The <Directory> code would merge and re-merge the same section after
9219 a match was found, possibly causing problems with some modules.
9222 *) ip-based vhosts are stored and queried using a hashing function, which
9223 has been shown to improve performance on servers with many ip-vhosts.
9224 Some other changes had to be made to accommodate this:
9225 - the * address for vhosts now behaves like _default_
9226 - the matching process now is:
9227 - match an ip-vhost directly via hash (possibly matches main
9229 - if that fails, just pretend it matched the main server
9230 - if so far only the main server has been matched, perform
9231 name-based lookups (ServerName, ServerAlias, ServerPath)
9232 *only on name-based vhosts*
9233 - if they fail, look for _default_ vhosts
9234 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
9236 *) dbmmanage overhaul:
9237 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
9238 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
9239 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
9240 - provide better seed for rand
9241 - prompt for password as per getpass(3) (turn off echo, read from
9243 - use "newstyle" crypt based on $Config{osname} ($^O)
9244 - will not add a user if already in database, use new `update' command
9246 - added `check' command to check a users' password
9247 - added `import' command to convert existing password text-files or
9248 dbm files exported with `view'
9249 - more descriptive usage, general cleanup, 'use strict' clean, etc.
9252 *) Added psocket() which is a pool form of socket(), various places within
9253 the proxy weren't properly blocking alarms while registering the cleanup
9254 for its sockets. bclose() now uses pclose() and pclosesocket(). There
9255 was a bug where the client socket was being close()d twice due a still
9256 registered cleanup. [Dean Gaudet]
9258 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
9261 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
9262 [Jason Venner <jason@idiom.com>] PR#667
9264 *) Enable ``=""'' for RewriteCond directives to match against
9265 the empty string. This is the preferred way instead of ``^$''.
9266 [Ralf S. Engelschall]
9268 *) Fixed an infinite loop in mod_imap for references above the server root
9269 [Dean Gaudet] PR#748
9271 *) mod_proxy now has a ReceiveBufferSize directive, similar to
9272 SendBufferSize, so that the TCP window can be set appropriately
9273 for LFNs. [Phillip A. Prindeville]
9275 *) mod_browser has been replaced by the more general mod_setenvif
9276 (courtesy of Paul Sutton). BrowserMatch* directives are still
9277 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
9278 UnSetEnvIfZero directives. [Ken Coar]
9280 *) "HostnameLookups double" forces double-reverse DNS to succeed in
9281 order for remote_host to be set (for logging, or for the env var
9282 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
9285 *) mod_access overhaul:
9286 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
9287 and cidr syntax (i.e. 10.1.0.0/16). PR#762
9288 - Critical path was sped up by pre-computing a few things at config time.
9289 - The undocumented syntax "allow user-agents" was removed,
9290 the replacement is "allow from env=foobar" combined with mod_browser.
9291 - When used with hostnames it now forces a double-reverse lookup
9292 no matter what the directory settings are. This double-reverse
9293 doesn't affect any of the other routines that use the remote
9294 hostname. In particular it's still passed to CGIs and the log
9295 without the double-reverse check. Related PR#860.
9298 *) When a large bwrite() occurs (larger than the internal buffer size),
9299 while there is already something in the buffer, apache will combine
9300 the large write and the buffer into a single writev(). (This is
9301 in anticipation of using mmap() for reading files.)
9304 *) In obscure cases where a partial socket write occurred while chunking,
9305 Apache would omit the chunk header/footer on the next block. Cleaned
9306 up other bugs/inconsistencies in error conditions in buff.c. Fixed
9307 a bug where a long pause in DNS lookups could cause the last packet
9308 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
9310 *) API: Added child_exit function to module structure. This is called
9311 once per "heavy-weight process" just before a server child exit()'s
9312 e.g. when max_requests_per_child is reached, etc.
9313 [Doug MacEachern, Dean Gaudet]
9315 *) mod_include cleanup showed that handle_else was being used to handle
9316 endif. It didn't cause problems, but it was cleaned up too.
9319 *) mod_cern_meta would attempt to find meta files for the directory itself
9320 in some cases, but not in others. It now avoids it in all cases.
9323 *) mod_mime_magic would core dump if there was a decompression error.
9324 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
9326 *) PORT: some variants of DGUX require -lsocket -lnsl
9327 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
9329 *) mod_autoindex now allows sorting of FancyIndexed directory listings
9330 by the various fields (name, size, et cetera), either in ascending
9331 or descending order. Just click on the column header. [Ken Coar]
9333 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
9334 CPUs like the Alpha. Apache still stores ints in pointers, but that's
9335 the relatively safe direction. [Dean Gaudet] PR#344
9337 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
9338 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
9340 *) child_main avoids an unneeded call to select() when there is only one
9341 listening socket. [Dean Gaudet]
9343 *) In the event that the server is starved for idle servers it will
9344 spawn 1, then 2, then 4, ..., then 32 servers each second,
9345 doubling each second. It'll also give a warning in the errorlog
9346 since the most common reason for this is a poor StartServers
9347 setting. The define MAX_SPAWN_RATE can be used to raise/lower
9348 the maximum. [Dean Gaudet]
9350 *) Apache now provides an effectively unbuffered connection for
9351 CGI scripts. This means that data will be sent to the client
9352 as soon as the CGI pauses or stops output; previously, Apache would
9353 buffer the output up to a fixed buffer size before sending, which
9354 could result in the user viewing an empty page until the CGI finished
9355 or output a complete buffer. It is no longer necessary to use an
9356 "nph-" CGI to get unbuffered output. Given that most CGIs are written
9357 in a language that by default does buffering (e.g. perl) this
9358 shouldn't have a detrimental effect on performance.
9360 "nph-" CGIs, which formerly provided a direct socket to the client
9361 without any server post-processing, were not fully compatible with
9362 HTTP/1.1 or SSL support. As such they would have had to implement
9363 the transport details, such as encryption or chunking, in order
9364 to work properly in certain situations. Now, the only difference
9365 between nph and non-nph scripts is "non-parsed headers".
9366 [Dean Gaudet, Sameer Parekh, Roy Fielding]
9368 *) If a BUFF is switched from buffered to unbuffered reading the first
9369 bread() will return whatever remained in the buffer prior to the
9370 switch. [Dean Gaudet]
9372 Changes with Apache 1.3a1
9374 *) Added another Configure helper script: TestLib. It determines
9375 if a specified library exists. [Jim Jagielski]
9377 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
9378 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
9381 *) PORT: Some architectures use size_t for various lengths in network
9382 functions such as accept(), and getsockname(). The definition
9383 NET_SIZE_T is used to control this. [Dean Gaudet]
9385 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
9386 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
9387 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
9389 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
9390 [Igor N Kovalenko <infoh@mail.wplus.net>]
9392 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
9393 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
9394 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
9395 [Dean Gaudet] related PR#875
9397 *) API: Correct child_init() slot declaration from int to void, to
9398 match the init() declaration. Update mod_example to use the new
9401 *) added transport handle slot (t_handle) to the BUFF structure
9404 *) get_client_block() returns wrong length if policy is
9405 REQUEST_CHUNKED_DECHUNK.
9406 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
9408 *) Support the image map format of FrontPage. For example:
9409 rect /url.hrm 10 20 30 40
9410 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
9412 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
9413 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
9415 *) AddModuleInfo directive for mod_info which allows you to annotate
9416 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9418 *) Added NoProxy directive to avoid using ProxyRemote for selected
9419 addresses. Added ProxyDomain directive to cause unqualified
9420 names to be qualified by redirection.
9421 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
9423 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
9424 header to the remote host in the proxy. [Sameer Parekh and
9427 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
9428 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
9429 URLs, fixed rewritelog(), fixed forced response code handling on
9430 redirects from within .htaccess files, disabled pipe locking under
9431 braindead SunOS 4.1.x, allow env variables to be set even on rules with
9432 no substitution, bugfixed situations where HostnameLookups is off, made
9433 mod_rewrite more thread-safe for NT port and fixed problem when creating
9434 an empty query string via "xxx?".
9435 This update also removes the copyright of Ralf S. Engelschall,
9436 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
9437 exclusively copyrighted by the Apache Group now. This happened because
9438 the author now has gifted mod_rewrite exclusively to the Apache Group and
9439 no longer maintains an external version.
9440 [Ralf S. Engelschall]
9442 *) API: Added child_init function to module structure. This is called
9443 once per "heavy-weight process" before any requests are handled.
9444 See http_config.h for more details. [Dean Gaudet]
9446 *) Anonymous_LogEmail was logging on each subrequest.
9447 [Dean Gaudet] PR#421, 868
9449 *) API: Added is_initial_req() which tests if the request being
9450 processed is the initial request, or a subrequest.
9453 *) Extended SSI (mod_include) now handles additional relops for
9454 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
9456 *) Configure fixed to correctly propagate user-selected options and
9457 settings (such as CC and OPTIM) to Makefiles other than
9458 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
9460 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
9461 directory indices to start with the contents of the HeaderName file
9462 if there is one. If there isn't one, the behaviour is unchanged.
9463 [Ken Coar, Roy Fielding, Andrey A. Chernov]
9465 *) WIN32: Modules can now be dynamically loaded DLLs using the
9466 LoadModule/LoadFile directives. Note that module DLLs must be
9467 compiled with the multithreaded DLL version of the runtime library.
9468 [Alexei Kosut and Ben Laurie]
9470 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
9471 This allows the admin to completely remove automatic indexing
9472 from the server, while still supporting the basic functions of
9473 trailing-slash redirects and DirectoryIndex files. Note that if
9474 you're carrying over an old Configuration file and you use directory
9475 indexing then you'll want to add:
9477 Module autoindex_module mod_autoindex.o
9479 before mod_dir in your Configuration. [Dean Gaudet]
9481 *) popendir/pclosedir created to properly protect directory scanning.
9482 [Dean Gaudet] PR#525
9484 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
9485 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
9486 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
9489 *) The AccessFileName directive can now take more than one filename.
9490 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9492 *) The new mod_mime_magic can be used to "magically" determine the type
9493 of a file if the extension is unknown. Based on the unix file(1)
9494 command. [Ian Kluft <ikluft@cisco.com>]
9496 *) We now determine and display the time spent processing a
9497 request if desired. [Jim Jagielski]
9499 *) mod_status: PID field of "dead" child slots no longer displays
9500 main httpd process's PID. [Jim Jagielski]
9502 *) Makefile.nt added - to build all the bits from the command line:
9503 nmake -f Makefile.nt
9504 Doesn't yet work properly. [Ben Laurie]
9506 *) Default text of 404 error is now "Not Found" rather than the
9507 potentially misleading "File Not Found". [Ken Coar]
9509 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
9510 for the net if we require people that actually need this data to
9511 enable it. [Linus Torvalds]
9513 *) directory_walk() is an expensive function, keep a little more state to
9514 avoid needless string counting. Add two new functions make_dirstr_parent
9515 and make_dirstr_prefix which replace all existing uses of make_dirstr.
9516 The new functions are a little less general than make_dirstr, but
9517 work more efficiently (less memory, less string counting).
9520 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
9521 to LDFLAGS) to avoid complications with lex rules in make files.
9522 [Dean Gaudet] PR#372
9524 *) run_method optimized to avoid needless scanning over NULLs in the
9525 module list. [Dean Gaudet]
9527 *) Revamp of (unix) scoreboard management code such that it avoids
9528 unnecessary traversals of the scoreboard on each hit. This is
9529 particularly important for high volume sites with a large
9530 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
9531 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
9532 httpd.h. [Dean Gaudet]
9534 *) In configurations using multiple Listen statements it was possible for
9535 busy sockets to starve other sockets of service. [Dean Gaudet]
9537 *) Added hook so standalone_main can be replaced at compile time
9538 (define STANDALONE_MAIN)
9541 *) Lowest-level read/write functions in buff.c will be replaced with
9542 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
9543 compile time. The default sfio discipline will behave as apache
9544 would without sfio compiled in.
9547 *) Enhance UserDir directive (mod_userdir) to accept a list of
9548 usernames for the 'disable' keyword, and add 'enable user...' to
9549 selectively *en*able userdirs if they're globally disabled.
9552 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
9553 will work with Netscape dbm files. (dbmmanage will probably not
9554 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
9556 *) Add a ListenBacklog directive to control the backlog parameter
9557 passed to listen(). Also change the default to 511 from 512.
9560 *) API: A new handler response DONE which informs apache that the
9561 request has been handled and it can finish off quickly, similar to
9562 how it handles errors. [Rob Hartill]
9564 *) Turn off chunked encoding after sending terminating chunk/footer
9565 so that we can't do it twice by accident. [Roy Fielding]
9567 *) mod_expire also issues Cache-Control: max-age headers.
9570 *) API: Added kill_only_once option for free_proc_chain so that it won't
9571 aggressively try to kill off specific children. For fastcgi.
9572 [Stanley Gambarin <gambarin@OpenMarket.com>]
9574 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
9576 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
9577 When used together, these cause mod_dir to emit HEIGHT and WIDTH
9578 attributes in the FancyIndexing IMG tags. [Ken Coar]
9580 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
9582 *) PORT: Added Windows NT support
9583 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
9585 Changes with Apache 1.2.6
9587 *) mod_include when using XBitHack Full would send ETags in addition to
9588 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
9589 [Dean Gaudet] PR#1133
9591 *) SECURITY: When a client connects to a particular port/addr, and
9592 gives a Host: header ensure that the virtual host requested can
9593 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
9595 *) Support virtual hosts with wildcard port and/or multiple ports
9596 properly. [Ed Korthof <ed@organic.com>]
9598 *) Fixed some case-sensitivity issues according to RFC2068.
9601 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
9602 and mod_include.c. [Dean Gaudet]
9604 *) Variable 'cwd' was being used pointlessly before being set.
9607 *) SIGURG doesn't exist on all platforms.
9608 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
9610 *) When an error occurs during a POST, or other operation with a
9611 request body, the body has to be read from the net before allowing
9612 a keepalive session to continue. [Roy Fielding] PR#1399
9614 *) When an error occurs in fcntl() locking suggest the user look up
9615 the docs for LockFile. [Dean Gaudet]
9617 *) table_set() and table_unset() did not deal correctly with
9618 multiple occurrences of the same key. [Stephen Scheck
9619 <sscheck@infonex.net>, Ben Laurie] PR#1604
9621 *) send_fd_length() did not calculate total_bytes_sent properly in error
9622 cases. [Ben Reser <breser@regnow.com>] PR#1366
9624 *) r->connection->user was allocated in the wrong pool causing corruption
9625 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
9627 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9628 Also removed the auto-generated link to www.apache.org that was the
9629 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
9631 *) Multiple "close" tokens may have been set in the "Connection"
9632 header, not an error, but a waste.
9633 [Ronald.Tschalaer@psi.ch] PR#1683
9635 *) "basic" and "digest" auth tokens should be tested case-insensitive.
9636 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
9638 *) It appears the "257th byte" bug (see
9639 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
9640 at the 256th byte as well. Fixed. [Dean Gaudet]
9642 *) mod_rewrite would not handle %3f properly in some situations.
9645 *) Apache could generate improperly chunked HTTP/1.1 responses when
9646 the bputc() or rputc() functions were used by modules (such as
9647 mod_include). [Dean Gaudet]
9649 *) #ifdef wrap a few #defines in httpd.h to make life easier on
9650 some ports. [Ralf Engelschall]
9652 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
9654 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
9656 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
9658 Changes with Apache 1.2.5
9660 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
9661 only an issue on systems without a MAXDNAME define or where
9662 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
9664 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
9667 *) Fix core dump in the ftp proxy when reading incorrectly formatted
9668 directory listings. [Marc Slemko]
9670 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
9673 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
9674 is used to read various types of files such as htaccess and
9675 htpasswd files. [Marc Slemko]
9677 *) SECURITY: Ensure that the buffer returned by ht_time is always
9678 properly null terminated. [Marc Slemko]
9680 *) SECURITY: General mod_include cleanup, including fixing several
9681 possible buffer overflows and a possible infinite loop. This cleanup
9682 was done against 1.3 code and then backported to 1.2, the result
9683 is a large difference (due to indentation cleanup in 1.3 code).
9684 Users interested in seeing a smaller set of relevant differences
9685 should consider comparing against src/modules/standard/mod_include.c
9686 from the 1.3b3 release. Non-indentation changes to mod_include
9687 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
9689 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9690 including fixing a possible buffer overflow. This cleanup also
9691 was done with 1.3 code as a basis, see the the previous note
9692 about mod_include. [Dean Gaudet]
9694 *) SECURITY: If a htaccess file can not be read due to bad
9695 permissions, deny access to the directory with a HTTP_FORBIDDEN.
9696 The previous behavior was to ignore the htaccess file if it could not
9697 be read. This change may make some setups with unreadable
9698 htaccess files stop working. PR#817 [Marc Slemko]
9700 *) SECURITY: no2slash() was O(n^2) in the length of the input.
9701 Make it O(n). This inefficiency could be used to mount a denial
9702 of service attack against the Apache server. Thanks to

9728 Changes with Apache 1.2.4
9730 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
9731 always making requests with the full-URI instead of just the URI path.

9735 on this platform. [Marc Slemko]
9737 Changes with Apache 1.2.3
9739 *) The request to a remote proxy was mangled if it was generated as the
9740 result of a ProxyPass directive. URL schemes other than http:// were not
9741 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

9745 information for case where proxy module is not available. [Marc Slemko]

9748 do for errors and cached responses. [Roy Fielding]
9750 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
9752 Changes with Apache 1.2.2 [not released]
9754 *) Fixed another long-standing bug in sub_req_lookup_file where it would
9755 happily skip past access checks on subdirectories looked up with relative
9756 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
9759 *) Add lockfile name to error message printed out when
9760 USE_FLOCK_SERIALIZED_ACCEPT is defined.
9763 *) Enhanced the chunking and error handling inside the buffer functions.
9764 [Dean Gaudet, Roy Fielding]
9766 *) When merging the main server's <Directory> and <Location> sections into
9767 a vhost, put the main server's first and the vhost's second. Otherwise
9768 the vhost can't override the main server. [Dean Gaudet] PR#717
9770 *) The <Directory> code would merge and re-merge the same section after
9771 a match was found, possibly causing problems with some modules.
9774 *) Fixed an infinite loop in mod_imap for references above the server root.
9775 [Dean Gaudet] PR#748
9777 *) mod_include cleanup showed that handle_else was being used to handle
9778 endif. It didn't cause problems, but it was cleaned up too.
9781 *) Last official synchronization of mod_rewrite with author version (because
9782 mod_rewrite is now directly developed by the author at the Apache Group):
9783 o added diff between mod_rewrite 3.0.6+ and 3.0.9
9784 minus WIN32/NT stuff, but plus copyright removement.
9786 - workaround for detecting infinite rewriting loops
9787 - fixed setting of env vars when "-" is used as subst string

9791 - fix for rewritelog in cases where remote hostname is unknown
9792 - fixed totally damaged request_rec walk-back loop
9793 o remove static from local data and add static to global ones.
9794 o replaced ugly proxy finding stuff by simple
9795 find_linked_module("mod_proxy") call.
9796 o added missing negation char on rewritelog()
9797 o fixed a few comment typos

9800 *) Anonymous_LogEmail was logging on each subrequest.
9801 [Dean Gaudet] PR#421, PR#868
9803 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
9804 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
9805 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

9807 a deficiency in the header_parse phase.

9825 under Solaris 2.x (up through 2.5.1). It has been fixed.
9826 [Dean Gaudet] PR#832
9828 *) API: In HTTP/1.1, whether or not a request message contains a body
9829 is independent of the request method and based solely on the presence
9830 of a Content-Length or Transfer-Encoding. Therefore, our default
9831 handlers need to be prepared to read a body even if they don't know
9832 what to do with it; otherwise, the body would be mistaken for the
9833 next request on a persistent connection. discard_request_body()
9834 has been added to take care of that. [Roy Fielding] PR#378
9836 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
9837 release version number, such that it always increases along the
9838 same lines as our source code branching. [Roy Fielding]

9842 Changes with Apache 1.2.1
9844 *) SECURITY: Don't serve file system objects unless they are plain files,

9850 could contain "../" allowing a local user to "publish" any file on
9851 the system. No slashes are allowed now. [Dean Gaudet]
9853 *) SECURITY: It was possible to violate the symlink Options using mod_dir
9854 (headers, readmes, titles), mod_negotiation (type maps), or
9855 mod_cern_meta (meta files). [Dean Gaudet]
9857 *) SECURITY: Apache will refuse to run as "User root" unless
9858 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
9860 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
9861 if it contained a .htaccess disallowing symlinks. This is contrary
9862 to the rule that symlink permissions are tested with the symlink
9863 options of the parent directory. [Dean Gaudet] PR#353
9865 *) CONFIG: The LockFile directive can be used to place the serializing
9866 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
9867 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
9870 *) Request processing now retains state of whether or not the request
9871 body has been read, so that internal redirects and subrequests will
9872 not try to read it twice (and block). [Roy Fielding]
9874 *) Add a placeholder in modules/Makefile to avoid errors with certain
9875 makes. [Marc Slemko]
9877 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

9883 *) Attempt to work around problems with third party libraries that do not
9884 handle high numbered descriptors (examples include bind, and
9885 solaris libc). On all systems apache attempts to keep all permanent
9886 descriptors above 15 (called the low slack line). Solaris users
9887 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
9888 which keeps all non-FILE * descriptors above 255. On all systems
9889 this should make supporting large numbers of vhosts with many open
9890 log files more feasible. If this causes trouble please report it,
9891 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
9892 [Dean Gaudet] various PRs
9894 *) Related to the last entry, network sockets are now opened before
9895 log files are opened. The only known case where this can cause
9896 problems is under Solaris with many virtualhosts and many Listen
9897 directives. But using -DHIGH_SLACK_LINE=256 described above will
9898 work around this problem. [Dean Gaudet]

9953 reading from one buffer and writing to another, at least until it has
9954 a custom timeout handler. [Roy Fielding and Petr Lampa]

9994 Module declaration. Also, be more understanding about the
9995 CC=/OPTIM= format in Configuration. Finally, fix compiler
9996 flags if using HP-UX's cc compiler. [Jim Jagielski]
9998 *) Subrequests and internal redirects now inherit the_request from the
9999 original request-line. [Roy Fielding]
10001 *) Test for error conditions before creating output header fields, since
10002 we don't want the error message to include those fields. Likewise,
10003 reset the content_language(s) and content_encoding of the response
10004 before generating or redirecting to an error message, since the new
10005 message will have its own Content-* definitions. [Dean Gaudet]

10008 and 304 responses) and err_headers_out (headers sent with all responses).
10009 Avoid the overhead of copying tables if err_headers_out is empty
10010 (the usual case). [Roy Fielding]

10013 not properly checking both the value configured by the DefaultType
10014 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value

10025 *) The method for determining PATH_INFO has been restored to the pre-1.2b
10026 (and NCSA httpd) definition wherein it was the extra path info beyond
10027 the CGI script filename. The environment variable FILEPATH_INFO has
10028 been removed, and instead we supply the original REQUEST_URI to any
10029 script that wants to be Apache-specific and needs the real URI path.
10030 This solves a problem with existing scripts that use extra path info
10031 in the ScriptAlias directive to pass options to the CGI script.
10034 *) The _default_ change in 1.2b10 will change the behaviour on configs
10035 that use multiple Listen statements for listening on multiple ports.
10036 But that change is necessary to make _default_ consistent with other
10037 forms of <VirtualHost>. It requires such configs to be modified
10038 to use <VirtualHost _default_:*>. The documentation has been
10039 updated. [Dean Gaudet] PR#530
10041 *) If an ErrorDocument CGI script is used to respond to an error
10042 generated by another CGI script which has already read the message

10122 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
10123 parsing of headers. If the terminating empty-line CRLF occurs starting
10124 at the 256th or 257th byte of output, then Navigator will think a normal
10125 image is invalid. We are guessing that this is because their initial
10126 read of a new request uses a 256 byte buffer. We check the bytes written
10127 so far and, if we are about to tickle the bug, we instead insert a
10128 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

10190 the special cases directly. [Dean Gaudet]
10192 *) We now try to log where the server is dumping core when a fatal
10193 signal is received. [Ken Coar]
10195 *) Improved lingering_close by adding a special timeout, removing the
10196 spurious log messages, removing the nonblocking settings (they
10197 are not needed with the better timeout), and adding commentary
10198 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
10199 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
10201 *) Send error messages about setsockopt failures to the server error
10202 log instead of stderr. [Roy Fielding]
10204 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
10206 *) Stopgap solution for CGI 3-second delay with server-side includes: if
10207 processing a subrequest, allocate memory from r->main->pool instead
10208 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
10209 in the middle of an SSI request. [Dean Gaudet] PR #122
10211 *) Fixed status of response when POST is received for a nonexistent URL
10212 (was sending 405, now 404) and when any method is sent with a
10213 full-URI that doesn't match the server and the server is not acting
10214 as a proxy (was sending 501, now 403). [Roy Fielding]
10216 *) Host port changed to unsigned short. [Ken Coar] PR #276
10218 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
10220 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
10222 *) Report extra info from errno with many errors that cause httpd to exit.
10223 spawn_child, popenf, and pclosef now have valid errno returns in the
10224 event of an error. Correct problems where errno was stomped on
10225 before being reported. [Dean Gaudet]
10227 *) In the proxy, if the cache filesystem was full, garbage_coll() was
10228 never called, and thus the filesystem would remain full indefinitely.
10229 We now also remove incomplete cache files left if the origin server
10230 didn't send a Content-Length header and either the client has aborted
10231 transfer or bwrite() to client has failed. [Petr Lampa]
10233 *) Fixed the handling of module and script-added header fields.
10234 Improved the interface for sending header fields and reduced
10235 the duplication of code between sending okay responses and errors.
10236 We now always send both headers_out and err_headers_out, and
10237 ensure that the server-reserved fields are not being overridden,
10238 while not overriding those that are not reserved. [Roy Fielding]
10240 *) Moved transparent content negotiation fields to err_headers_out
10241 to reflect above changes. [Petr Lampa]
10243 *) Fixed the determination of whether or not we should make the
10244 connection persistent for all of the cases where some other part
10245 of the server has already indicated that we should not. Also
10246 improved the ordering of the test so that chunked encoding will
10247 be set whenever it is desired instead of only when KeepAlive
10248 is enabled. Added persistent connection capability for most error
10249 responses (those that do not indicate a bad input stream) when
10250 accessed by an HTTP/1.1 client. [Roy Fielding]
10252 *) Added missing timeouts for sending header fields, error responses,
10253 and the last chunk of chunked encoding, each of which could have
10254 resulted in a process being stuck in write forever. Using soft_timeout
10255 requires that the sender check for an aborted connection rather than
10256 continuing after an EINTR. Timeouts that used to be initiated before
10257 send_http_header (and never killed) are now initiated only within or
10258 around the routines that actually do the sending, and not allowed to
10259 propagate above the caller. [Roy Fielding]
10261 *) mod_auth_anon required an @ or a . in the email address, not both.
10264 *) per_dir_defaults weren't set correctly until directory_walk for
10265 name-based vhosts. This fixes an obscure bug with the wrong config
10266 info being used for vhosts that share the same ip as the server.
10269 *) Improved generation of modules/Makefile to be more generic for
10270 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
10272 *) Generate makefile dependency for Configuration based on the actual
10273 name given when running the Configure process. [Dean Gaudet]
10275 *) Fixed problem with vhost error log not being set prior to
10276 initializing virtual hosts. [Dean Gaudet]
10278 *) Fixed infinite loop when a trailing slash is included after a type map
10279 file URL (extra path info). [Petr Lampa]
10281 *) Fixed server status updating of per-connection counters. [Roy Fielding]
10283 *) Add documentation for DNS issues (reliability and security), and try
10284 to explain the virtual host matching process. [Dean Gaudet]
10286 *) Try to continue gracefully by disabling the vhost if a DNS lookup
10287 fails while parsing the configuration file. [Dean Gaudet]
10289 *) Improved calls to setsockopt. [Roy Fielding]
10291 *) Negotiation changes: Don't output empty content-type in variant list;
10292 Output charset in variant list; Return sooner from handle_multi() if
10293 no variants found; Add handling of '*' wildcard in Accept-Charset.
10294 [Petr Lampa and Paul Sutton]
10296 *) Fixed overlaying of request/sub-request notes and headers in
10297 mod_negotiation. [Dean Gaudet]
10299 *) If two variants' charset quality are equal and one is the default
10300 charset (iso-8859-1), then prefer the variant that was specifically
10301 listed in Accept-Charset instead of the default. [Petr Lampa]
10303 *) Memory allocation problem in push_array() -- it would corrupt memory
10304 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
10306 *) invoke_handler() doesn't handle mime arguments in content-type
10307 [Petr Lampa] PR#160
10309 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
10312 *) Fixed problem with ErrorDocument not working for virtual hosts
10313 due to one of the performance changes in 1.2b7. [Dean Gaudet]
10315 *) Log an error message if we get a request header that is too long,
10316 since it may indicate a buffer overflow attack. [Marc Slemko]
10318 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
10319 not reject URLs without a double-slash, as per RFC2068 section 3.2.
10320 [Ken Coar] PR #146, #187
10322 *) Added table entry placeholder for new header_parser callback
10323 in all of the distributed modules. [Ken Coar] PR #191
10325 *) Allow for cgi files without the .EXE extension on them under OS/2.
10326 [Garey Smiley] PR #59
10328 *) Fixed error message when resource is not found and URL contains
10329 path info. [Petr Lampa and Dean Gaudet] PR #40
10331 *) Fixed user and server confusion over what should be a virtual host
10332 and what is the main server, resulting in access to something
10333 other than the name defined in the virtualhost directive (but
10334 with the same IP address) failing. [Dean Gaudet]
10336 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
10337 AIX; improves the redirection stuff to enable the users to generally
10338 redirect to http, https, gopher and ftp; added TIME variable for
10339 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
10340 special patterns >STRING, <STRING and =STRING to RewriteCond, which
10341 can be used in conjunction with %{TIME} or other variables to create
10342 time-dependent rewriting rules. [Ralf S. Engelschall]
10344 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
10345 Module authors may need to adjust their code for proper cleanup to take
10346 place (that is, call note_cleanups_for_fd()). This change fixes problems
10347 with file descriptors being erroneously closed when the proxy module was
10348 in use. [Ben Laurie]
10350 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
10351 initgroups() to hose the group information needed for later
10352 comparisons. [Randy Terbush]
10354 *) Remove unnecessary call to va_end() in create_argv() which
10355 caused a SEGV on some systems.
10357 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
10360 *) Clear memory allocated for listeners. [Randy Terbush]
10362 *) Improved handling of IP address as a virtualhost address and
10363 introduced "_default_" as a synonym for the default vhost config.
10364 [Dean Gaudet] PR #212
10366 Changes with Apache 1.2b7
10368 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
10370 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
10372 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
10373 - replace protocol response numbers with symbols
10374 - save variant-list into main request notes
10375 - free allocated memory from subrequests
10376 - merge notes, headers_out and err_headers_out
10378 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
10379 "HTTP/#.# ###*" to be more lenient about what we accept.
10382 *) more proxy FTP bug fixes:
10383 - Changed send_dir() to remove user/passwd from displayed URL.
10384 - Changed login error messages to be more descriptive.
10385 - remove setting of SO_DEBUG socket option
10386 - Make ftp_getrc() more lenient about multiline responses,
10387 specifically, 230 responses which don't have continuation 230-
10388 on each line). These seem to be all NT FTP servers, and while
10389 perhaps questionable, they appear to be legal by RFC 959.
10390 - Add missing kill_timeout() after transfer to user completes.
10393 *) Fixed problem where a busy server could hang when restarting
10394 after being sent a SIGHUP due to child processes not exiting.
10397 *) Modify mod_include escaping so a '\' only signifies an escaped
10398 character if the next character is one that needs
10399 escaping. [Ben Laurie]
10401 *) Eliminated possible infinite loop in mod_imap when relative URLs are
10402 used with a 'base' directive that does not have a '/' in it.
10403 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
10405 *) Reduced the default timeout from 1200 seconds to 300, and the
10406 one in the sample configfile from 400 to 300. [Marc Slemko]
10408 *) Stop vbprintf from crashing if given a NULL string pointer;
10409 print (null) instead. [Ken Coar]
10411 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
10412 [Marc Slemko and Roy Fielding]
10414 *) Fixed problem with mod_cgi-generated internal redirects trying to
10415 read the request message-body twice. [Archie Cobbs and Roy Fielding]
10417 *) Reduced timeout on lingering close, removed possibility of a blocked
10418 read causing the child to hang, and stopped logging of errors if
10419 the socket is not connected (reset by client). [Roy Fielding]
10421 *) Rearranged main child loop to remove duplication of code in
10422 select/accept and keep-alive requests, fixed several bugs regarding
10423 checking scoreboard_image for exit indication and failure to
10424 account for all success conditions and trap all error conditions,
10425 prevented multiple flushes before closing the socket; close the entire
10426 socket buffer instead of just one descriptor, prevent logging of
10427 EPROTO and ECONNABORTED on platforms where supported, and generally
10428 improved readability. [Roy Fielding]
10430 *) Extensive performance improvements. Cleaned up inefficient use of
10431 auto initializers, multiple is_matchexp calls on a static string,
10432 and excessive merging of response_code_strings. [Dean Gaudet]
10434 *) Added double-buffering to mod_include to improve performance on
10435 server-side includes. [Marc Slemko]
10437 *) Several fixes for suexec wrapper. [Randy Terbush]
10438 - Make wrapper work for files on NFS filesystem.
10439 - Fix portability problem of MAXPATHLEN.
10440 - Fix array overrun problem in clean_env().
10441 - Fix allocation of PATH environment variable
10443 *) Removed extraneous blank line is description of mod_status chars.
10446 *) Logging of errors from the call_exec routine simply went nowhere,
10447 since the logfile fd has been closed, so now we send them to stderr.
10448 [Harald T. Alvestrand]
10450 *) Fixed core dump when DocumentRoot is a CGI.
10451 [Ben Laurie, reported by geddis@tesserae.com]
10453 *) Fixed potential file descriptor leak in mod_asis; updated it and
10454 http_core to use pfopen/pfclose instead of fopen/fclose.
10455 [Randy Terbush and Roy Fielding]
10457 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
10458 as the DEC Alpha which is 64-bit but uses 32-bit ints.
10459 [Dean Gaudet and Ken Coar]
10461 *) Return a 302 response code to the client when sending a redirect
10462 due to a missing trailing '/' on a directory instead of a 301; now
10463 it is cacheable. [Markus Gyger]
10465 *) Fix condition where, if a bad directive occurs in .htaccess, and
10466 sub_request() goes first to this directory, then log_reason() will
10467 SIGSEGV because it doesn't have initialized r->per_dir_config.
10468 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
10470 *) Fix handling of lang_index in is_variant_better(). This was
10471 causing problems which resulted in the server sending the
10472 wrong language document in some cases. [Petr Lampa]
10474 *) Remove free() from clean_env() in suexec wrapper. This was nuking
10475 the clean environment on some systems.
10477 *) Tweak byteserving code (e.g. serving PDF files) to work around
10478 bugs in Netscape Navigator and Microsoft Internet Explorer.
10479 Emit Content-Length header when sending multipart/byteranges.
10482 *) Port to HI-UX/WE2. [Nick Maclaren]
10484 *) Port to HP MPE operating system for HP 3000 machines
10485 [Mark Bixby <markb@cccd.edu>]
10487 *) Fixed bug which caused a segmentation fault if only one argument
10488 given to RLimit* directives. [Ed Korthof]
10490 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
10492 *) Improved buffered output to the client by delaying the flush decision
10493 until the BUFF code is actually about to read the next request.
10494 This fixes a problem introduced in 1.2b5 with clients that send
10495 an extra CRLF after a POST request. Also improved chunked output
10496 performance by combining writes using writev() and removing as
10497 many bflush() calls as possible. NOTE: Platforms without writev()
10498 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
10499 or Configure, unless we have already done so. [Dean Gaudet]
10501 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
10503 *) Fixed mod_info output corruption bug introduced by buffer overflow
10504 fixes. [Dean Gaudet]
10506 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
10507 for the special case of a 304 response. [Paul Sutton]
10509 *) Improved handling of TRACE method by bypassing normal method handling
10510 and header parsing routines; fixed Allow response to always allow TRACE.
10513 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
10515 *) Cleaned-up some of the generated HTML. [Ken Coar]
10517 Changes with Apache 1.2b6
10519 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
10521 *) Fix typo introduced in fix for potential infinite loop around
10522 accept() in child_main(). This change caused the rev to 1.2b6.
10523 1.2b5 was never a public beta.
10525 Changes with Apache 1.2b5
10527 *) Change KeepAlive semantics (On|Off instead of a number), add
10528 MaxKeepAliveRequests directive. [Alexei Kosut]
10530 *) Various NeXT compilation patches, as well as a change in
10531 regex/regcomp.c since that file also used a NEXT define.
10534 *) Allow * to terminate the end of a directory match in mod_dir.
10535 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
10537 *) Don't call can_exec() if suexec_enabled. Calling this requires
10538 scripts executed by the suexec wrapper to be world executable, which
10539 defeats one of the advantages of running the wrapper. [Randy Terbush]
10541 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
10544 *) Migration from sprintf() to snprintf() to avoid buffer
10545 overflows. [Marc Slemko]
10547 *) Provide portable snprintf() implementation (ap_snprintf)
10548 as well as *cvt family. [Jim Jagielski]
10550 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
10553 *) Remove mod_fastcgi.c from the distribution. This module appears
10554 to be maintained more through the Open Market channels and should
10555 continue to be easily available at http://www.fastcgi.com/
10557 *) Fixed bug in modules/Makefile that wouldn't allow building in more
10558 than one subdirectory (or cleaning, either). [Jeremy Laidman]
10560 *) mod_info assumed that the config files were relative to ServerRoot.
10563 *) CGI scripts called as an error document resulting from failed
10564 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
10566 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
10569 *) Properly check errno to prevent display of a directory index
10570 when server receives a long enough URL to confuse stat().
10573 *) Several security enhancements to suexec wrapper. It is _highly_
10574 recommended that previously installed versions of the wrapper
10575 be replaced with this version. [Randy Terbush, Jason Dour]
10577 - ~user execution now properly restricted to ~user's home
10578 directory and below.
10579 - execution restricted to UID/GID > 100
10580 - restrict passed environment to known variables
10581 - call setgid() before initgroups() (portability fix)
10582 - remove use of setenv() (portability fix)
10584 *) Add HTTP/1.0 response forcing. [Ben Laurie]
10586 *) Add access control via environment variables. [Ben Laurie]
10588 *) Add rflush() function. [Alexei Kosut]
10590 *) remove duplicate pcalloc() call in new_connection().
10592 *) Fix incorrect comparison which could allow number of children =
10593 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
10594 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
10596 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
10597 AIX PS/2, CONVEXOS. [Jim Jagielski]
10599 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
10600 It's more portable. [Martin Kraemer]
10602 *) Replace references to make in Makefile.tmpl with $(MAKE).
10605 *) Add ProxyBlock directive w/IP address caching. Add IP address
10606 caching to NoCache directive as well. ProxyBlock works with all
10607 handlers; NoCache now also works with FTP for anonymous logins.
10608 Still more code cleanup. [Chuck Murcko]
10610 *) Add "header parse" API hook [Ben Laurie]
10612 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
10614 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
10616 *) Correctly allow access and auth directives in <Files> sections in
10617 server config files. [Alexei Kosut]
10619 *) Fix bug with ServerPath that could cause certain files to be not
10620 found by the server. [Alexei Kosut]
10622 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
10623 double-quote from text and so that it properly checks for unsupported
10624 status codes using the new index_of_response interface. [Roy Fielding]
10626 *) Multiple fixes to the lingering_close code in order to avoid being
10627 interrupted by a stray timeout, to avoid lingering on a connection
10628 that has already been aborted or never really existed, to ensure that
10629 we stop lingering as soon as any error condition is received, and to
10630 prevent being stuck indefinitely if the read blocks. Also improves
10631 reporting of error conditions. [Marc Slemko and Roy Fielding]
10633 *) Fixed initialization of parameter structure for sigaction.
10634 [mgyger@itr.ch, Adrian Filipi-Martin]
10636 *) Fixed reinitializing the parameters before each call to accept and
10637 select, and removed potential for infinite loop in accept.
10638 [Roy Fielding, after useful PR from adrian@virginia.edu]
10640 *) Fixed condition where, if a child fails to fork, the scoreboard would
10641 continue to say SERVER_STARTING forever. Eventually, the main process
10642 would refuse to start new children because count_idle_servers() will
10643 count those SERVER_STARTING entries and will always report that there
10644 are enough idle servers. [Phillip Vandry]
10646 *) Fixed bug in bcwrite regarding failure to account for partial writes.
10647 Avoided calling bflush() when the client is pipelining requests.
10648 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
10650 *) Added description of "." mode in server-status [Jim Jagielski]
10652 Changes with Apache 1.2b4
10654 *) Fix possible race condition in accept_mutex_init() that
10655 could leave a small security hole open allowing files to be
10656 overwritten in cases where the server UID has write permissions.
10659 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
10661 *) Fix portablity problem in util_script where ARG_MAX may not be
10662 defined for some systems.
10664 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
10667 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
10668 style magic #! token for better script portability. [Garey Smiley]
10670 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
10671 execution for ~userdir CGI. [Jason Dour]
10673 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
10675 *) Fix month off by one in suexec wrapper logging.
10677 Changes with Apache 1.2b3:
10679 *) Fix error in mod_cgi which could cause resources not to be properly
10680 freed, or worse. [Dean Gaudet]
10682 *) Fix find_string() NULL pointer dereference. [Howard Fear]
10684 *) Add set_flag_slot() at the request of Dirk and others.
10687 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
10689 *) Add changes to improve the error message given for invalid
10690 ServerName parameters. [Dirk vanGulik]
10692 *) Add "Authoritative" directive for Auth modules that don't
10693 currently have it. This gives admin control to assign authoritative
10694 control to an authentication scheme and allow "fall through" for
10695 those authentication modules that aren't "Authoritative" thereby
10696 allowing multiple authentication mechanisms to be chained.
10699 *) Remove requirement for ResourceConfig/AccessConfig if not using
10700 the three config file layout. [Randy Terbush]
10702 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
10704 *) Changes to suexec wrapper to fix the following problems:
10705 1. symlinked homedirs will kill ~userdirs.
10706 2. initgroups() on Linux 2.0.x clobbers gr->grid.
10707 3. CGI command lines paramters problems
10708 4. pw-pwdir for "docroot check" still the httpd user's pw record.
10709 [Randy Terbush, Jason Dour]
10711 *) Change create_argv() to accept variable arguments. This fixes
10712 a problem where arguments were not getting passed to the CGI via
10713 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
10715 *) Collapse multiple slashes in path URLs to properly apply
10716 handlers defined by <Location>. [Alexei Kosut]
10718 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
10720 *) Improve the accuracy of request duration timings by setting
10721 r->request_time in read_request_line() instead of read_request().
10724 *) Reset timeout while reading via get_client_block() in mod_cgi.c
10725 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
10727 *) Add the ability to pass different Makefile.tmpl files to Configure
10728 using the -make flag. [Rob Hartill]
10730 *) Fix coredump triggered when sending a SIGHUP to the server caused
10731 by an assertion failure, in turn caused by an uninitialised field in a
10735 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
10736 PATH_INFO from previous versions of Apache (in certain situations,
10737 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
10738 [later removed in 1.2b11]
10740 *) Add rwrite() function to API to allow for sending strings of
10741 arbitrary length. [Doug MacEachern]
10743 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
10745 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
10746 NeXT. [Jim Jagielski]
10748 *) Removed recent modification to promote the status code on internal
10749 redirects, since the correct fix was to change the default log format
10750 in mod_log_config so that it outputs the original status. [Rob Hartill]
10752 Changes with Apache 1.2b2:
10754 *) Update set_signals() to use sigaction() for setting handlers.
10755 This appears to fix a re-entrant problem in the seg_fault()
10756 bus_error() handlers. [Randy Terbush]
10758 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
10760 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
10762 *) proxy_http.c bugfixes: [Chuck Murcko]
10763 1) fixes possible NULL pointer reference w/NoCache
10764 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
10765 host would cache nothing if it was in the local domain,
10766 and the local domain was in the NoCache list)
10767 3) Adds Host: header when not available
10768 4) Some code cleanup and clarification
10770 *) mod_include.c bugfixes:
10771 1) Fixed an ommission that caused include variables to not
10772 be parsed in config errmsg directives [Howard Fear]
10773 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
10774 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
10775 4) Allow backslash-escaping to all quoted text
10776 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
10777 5) Pass variable to command line if not set in XSSI's env
10780 *) Fix infinite loop when processing Content-language lines in
10781 type-map files. [Alexei Kosut]
10783 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
10785 *) Fixed problem in set_[user|group] that prevented CGI execution
10786 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
10788 *) Added PORTING information file. [Jim Jagielski]
10790 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
10792 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
10794 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
10795 USE_FCNTL_SERIALIZED_ACCEPT was intended.
10797 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
10798 which caused problems of systems where socket s_addr is >32bits.
10800 *) Added comment to explain (r->chunked = 1) side-effect in
10801 http_protocol.c [Roy Fielding]
10803 *) Replaced use of index() in mod_expires.c with more appropriate
10804 and portable isdigit() test. [Ben Laurie]
10806 *) Updated Configure for ...
10807 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
10808 *-dg-dgux* (bad pattern match)
10809 QNX (DEF_WANTHSREGEX=yes)
10810 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
10812 *-unixware211 (new)
10813 and added some user diagnostic info. [Ben Laurie]
10815 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
10816 for better portability. [Jim Jagielski]
10818 *) Updated helpers/GuessOS for ...
10819 SCO 5 (recognize minor releases)
10820 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
10821 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
10822 IRIX64 (-sgi-irix64)
10823 ULTRIX (-unknown-ultrix)
10824 SINIX (-whatever-sysv4)
10825 NCR Unix (-ncr-sysv4)
10826 and fixed something in helpers/PrintPath [Ben Laurie]
10828 Changes with Apache 1.2b1
10830 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
10832 Changes with Apache 1.1.1
10834 *) Fixed bug where Cookie module would make two entries in the
10835 logfile for each access [Mark Cox]
10837 *) Fixed bug where Redirect in .htaccess files would cause memory
10838 leak. [Nathan Neulinger]
10840 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
10842 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
10844 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
10846 Changes with Apache 1.1.0
10848 *) Bring NeXT support up to date. [Takaaki Matsumoto]
10850 *) Bring QNX support up to date. [Ben Laurie]
10852 *) Make virtual hosts default to main server keepalive parameters.
10853 [Alexei Kosut, Ben Laurie]
10855 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
10857 *) Fix missing address family for connect, also remove unreachable statement
10858 in mod_proxy. [Ben Laurie]
10860 *) mod_env now turned on by default in Configuration.tmpl.
10862 *) Bugs which were fixed:
10863 a) yet more mod_proxy bugs [Ben Laurie]
10864 b) CGI works again with inetd [Alexei Kosut]
10865 c) Leading colons were stripped from passwords [osm@interguide.com]
10866 d) Another fix to multi-method Limit problem [jk@tools.de]
10868 Changes with Apache 1.1b4
10870 *) r->bytes_sent variable restored. [Robert Thau]
10872 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
10874 *) More possibly unsecure programs removed from the support directory.
10876 *) More mod_auth_msql authentication improvements.
10878 *) VirtualHosts based on Host: headers no longer conflict with the
10881 *) OS/2 compatibility enhancements. [Gary Smiley]
10883 *) POST now allowed to directory index CGI scripts.
10885 *) Actions now work with files of the default type.
10887 *) Bugs which were fixed:
10888 a) more mod_proxy bugs
10889 b) early termination of inetd requests
10890 c) compile warnings on several systems
10891 d) problems when scripts stop reading output early
10893 Changes with Apache 1.1b3
10895 *) Much of cgi-bin and all of cgi-src has been removed, due to
10896 various security holes found and that we could no longer support
10899 *) The "Set-Cookie" header is now special-cased to not merge multiple
10900 instances, since certain popular browsers can not handle multiple
10901 Set-Cookie instructions in a single header. [Paul Sutton]
10903 *) rprintf() added to buffer code, occurrences of sprintf removed.
10906 *) CONNECT method for proxy module, which means tunneling SSL should work.
10907 (No crypto needed) Also a NoCache config directive.
10909 *) Several API additions: pstrndup(), table_unset() and get_token()
10910 functions now available to modules.
10912 *) mod_imap fixups, in particular Location: headers are now complete
10915 *) New "info" module which reports on installed module set through a
10916 special URL, a la mod_status.
10918 *) "ServerPath" directive added - allows for graceful transition
10919 for Host:-header-based virtual hosts.
10921 *) Anonymous authentication module improvements.
10923 *) MSQL authentication module improvements.
10925 *) Status module design improved - output now table-based. [Ben Laurie]
10927 *) htdigest utility included for use with digest authentication
10930 *) mod_negotiation: Accept values with wildcards to be treated with
10931 less priority than those without wildcards at the same quality
10932 value. [Alexei Kosut]
10934 *) Bugs which were fixed:
10935 a) numerous mod_proxy bugs
10936 b) CGI early-termination bug [Ben Laurie]
10937 c) Keepalives not working with virtual hosts
10938 d) RefererIgnore problems
10939 e) closing fd's twice in mod_include (causing core dumps on
10940 Linux and elsewhere).
10942 Changes with Apache 1.1b2
10945 a) core dumps in mod_digest
10946 b) truncated hostnames/ip address in the logs
10947 c) relative URL's in mod_imap map files
10949 Changes with Apache 1.1b1
10951 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
10953 Changes with Apache 1.0.3
10955 *) Internal redirects which occur in mod_dir.c now preserve the
10956 query portion of a request (the bit after the question mark).
10959 *) Escape active characters '<', '>' and '&' in html output in
10960 directory listings, error messages and redirection links.
10963 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
10965 *) Fix for POSIX compliance in waiting for processes in alloc.c.
10968 *) setsockopt no longer takes a const declared argument [Martijn Koster]
10970 *) Reset timeout timer after each successful fwrite() to the network.
10971 This patch adds a reset_timeout() procedure that is called by
10972 send_fd() to reset the timeout ever time data is written to the net.
10975 *) timeout() signal handler now checks for SIGPIPE and reports
10976 lost connections in a more user friendly way. [Rob Hartill]
10978 *) Location of the "scoreboard" file which used to live in /tmp is
10979 now configurable (for OSes that can't use mmap) via ScoreBoardFile
10980 which works similar to PidFile (in httpd.conf) [Rob Hartill]
10982 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
10984 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
10985 which caused a SEGV with cookies enabled
10987 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
10990 *) Log the UNIX textual error returned by some system calls, in
10991 particular errors from accept() [David Robinson]
10993 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
10995 Changes with Apache 1.0.2
10997 *) patch to get Apache compiled on UnixWare 2.x, recommended as
10998 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
11000 *) Fix get_basic_auth_pw() to set the auth_type of the request.
11003 *) past changes to http_config.c to only use the
11004 setrlimit function on systems defining RLIMIT_NOFILE
11005 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
11006 for SUNOS and prototypes the needed functions.
11008 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
11011 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
11013 *) Merge multiple headers from CGI scripts instead of taking last
11014 one. [David Robinson]
11016 *) Add support for SCO 5. [Ben Laurie]
11018 Changes with Apache 1.0.1
11020 *) Silence mod_log_referer and mod_log_agent if not configured
11023 *) Recursive includes can occur if the client supplies PATH_INFO data
11024 and the server provider uses relative links; as file.html
11025 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
11027 *) The replacement for initgroups() did not call {set,end}grent(). This
11028 had two implications: if anything else used getgrent(), then
11029 initgroups() would fail, and it was consuming a file descriptor.
11032 *) On heavily loaded servers it was possible for the scoreboard to get
11033 out of sync with reality, as a result of a race condition.
11034 The observed symptoms are far more Apaches running than should
11035 be, and heavy system loads, generally followed by catastrophic
11036 system failure. [Ben Laurie]
11038 *) Fix typo in license. [David Robinson]
11040 Changes with Apache 1.0.0 23 Nov 1995
11042 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
11044 Changes with Apache 0.8.16 05 Nov 1995
11046 *) New man page for 'httpd' added to support directory [David Robinson]
11048 *) .htgroup files can have more than one line giving members for a
11049 given group (each must have the group name in front), for NCSA
11050 back-compatibility [Robert Thau]
11052 *) Mutual exclusion around accept() is on by default for SVR4 systems
11053 generally, since they generally can't handle multiple processes in
11054 accept() on the same socket. This should cure flaky behavior on
11055 a lot of those systems. [David Robinson]
11057 *) AddType, AddEncoding, and AddLanguage directives take multiple
11058 extensions on a single command line [David Robinson]
11060 *) UserDir can be disabled for a given virtual host by saying
11061 "UserDir disabled" in the <VirtualHost> section --- it was a bug
11062 that this didn't work. [David Robinson]
11064 *) Compiles on QNX [Ben Laurie]
11066 *) Corrected parsing of ctime time format [David Robinson]
11068 *) httpd does a perror() before exiting if it can't log its pid
11069 to the PidFile, to make diagnosing the error a bit easier.
11072 *) <!--#include file="..."--> can no longer include files in the
11073 parent directory, for NCSA back-compatibility. [David Robinson]
11075 *) '~' is *not* escaped in URIs generated for directory listings
11078 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
11080 *) Fixed bug involving handling URIs with escaped %-characters
11081 in redirects [David Robinson]
11083 Changes with Apache 0.8.15 14 Oct 1995
11085 *) Switched to new, simpler license
11087 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
11089 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
11091 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
11093 *) Correctly handles internal redirects to files with names containing '%'
11096 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
11098 *) Use geteuid() rather than getuid() to see if we have root privilege,
11099 so that server correctly resets privilege if run setuid root. [Andrew
11102 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
11105 *) Fix relative URLs in imagemap files [Randy Terbush]
11107 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
11110 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
11111 entries all name the same one. [David Robinson]
11113 *) Fix directory listings with filenames containing unusual characters
11116 *) Better URI-escaping for generated URIs in directories with filenames
11117 containing unusual characters [Ben Laurie]
11119 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
11121 *) Unblock alarms on error return from spawn_child() [David Robinson]
11123 *) Sample Config files have extra note for SCO users [Ben Laurie]
11125 *) Configuration has note for HP-UX users [Rob Hartill]
11127 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
11129 *) Nuked bogus #define in httpd.h [David Robinson]
11131 *) Better test for whether a system has setrlimit() [David Robinson]
11133 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
11135 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
11138 Changes with Apache 0.8.14 19 Sep 1995
11140 *) Compiles on SCO ODT 3.0 [Ben Laurie]
11142 *) AddDescription works (better) [Ben Laurie]
11144 *) Leaves an intelligible error diagnostic when it can't set group
11145 privileges on standalone startup [Andrew Wilson]
11147 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
11148 that machine, which claims to be BSD but does not support RLIMIT.
11151 *) gcc -Wall no longer complains about an unused variable when util.c
11152 is compiled with -DMINIMAL_DNS [Andrew Wilson]
11154 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
11156 Changes with Apache 0.8.13 07 Sep 1995
11158 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
11160 *) Have built-in imagemap code recognize & honor Point directive [James
11163 *) Generate cleaner directory listings in directories with a mix of
11164 long and short filenames [Rob Hartill]
11166 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
11168 *) Properly default ServerName for virtual servers [Robert Thau]
11170 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
11171 Paul Richards and a cast of thousands...]
11173 *) On self-identified BSD systems (we don't try to guess any more),
11174 allocate a few extra file descriptors per virtual host with setrlimit,
11175 if we can, to avoid running out. [Randy Terbush]
11177 *) Write 22-character lock file name into buffer with enough space
11178 on startup [Konstantin Olchanski]
11180 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
11183 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
11185 *) Suppress -Wall warning by initializing variable in negotiation code
11186 [Tobias Weingartner]
11188 Changes with Apache 0.8.12 31 Aug 1995
11190 *) Doesn't pause three seconds after including a CGI script which is
11191 too slow to die off (this is done by not even trying to kill off
11192 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
11193 after the entire document has been processed). [Robert Thau]
11195 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
11197 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
11199 *) Allows .htaccess files to override <Directory> sections naming the
11200 same directory [David Robinson]
11202 *) Removed an efficiency hack in sub_req_lookup_uri which was
11203 causing certain extremely marginal cases (e.g., ScriptAlias of a
11204 *particular* index.html file) to fail. [David Robinson]
11206 *) Doesn't log an error when the requested URI requires
11207 authentication, but no auth header line was supplied by the
11208 client; this is a normal condition (the client doesn't no auth is
11209 needed here yet). [Robert Thau]
11211 *) Behaves more sanely when the name server loses its mind [Sean Welch]
11213 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
11215 *) RFC931 code no longer passes out name of prior clients on current
11216 requests if the current request came from a server that doesn't
11217 do RFC931. [David Robinson]
11219 *) Configuration script accepts "Module" lines with trailing whitespace.
11222 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
11224 *) Cleaned up comments in mod_cgi.c [Robert Thau]
11226 Changes with Apache 0.8.11 24 Aug 1995
11228 *) Wildcard <Directory> specifications work. [Robert Thau]
11230 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
11232 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
11233 the file being requested itself, in addition to the directories leading
11234 up to it. [Robert Thau]
11236 *) Logs access failures due to symlink checks or invalid client address
11237 in the error log [Roy Fielding, Robert Thau]
11239 *) Symlink checks deal correctly with systems where lstat of
11240 "/path/to/some/link/" follows the link. [Thau, Fielding]
11242 *) Doesn't reset DirectoryIndex to 'index.html' when
11243 other directory options are set in a .htaccess file. [Robert Thau]
11245 *) Clarified init code and nuked bogus warning in mod_access.c
11246 [Florent Guillaume]
11248 *) Corrected several directives in sample srm.conf
11249 --- includes corrections to directory indexing icon-related directives
11250 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
11251 icons for encodings right, and turning on AddEncoding by default).
11254 *) Corrected descriptions of args to AddIcon and AddAlt in command table
11257 *) INSTALL & README mention "contributed modules" directory [Brian
11260 *) Fixed English in the license language... "for for" --> "for".
11263 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
11264 mod_alias.c, merging it almost completely with handling of Alias, and
11265 adding a 'notes' field to the request_rec which allows the CGI module
11266 to discover whether the Alias module has put this request through
11267 ScriptAlias (which it needs to know for back-compatibility, as the old
11268 NCSA code did not check Options ExecCGI in ScriptAlias directories).
11271 Changes with Apache 0.8.10 18 Aug 1995
11273 *) AllowOverride applies to the named directory, and not just
11274 subdirectories. [David Robinson]
11276 *) Do locking for accept() exclusion (on systems that need it)
11277 using a special file created for the purpose in /usr/tmp, and
11278 not the error log; using the error log causes real problems
11279 if it's NFS-mounted; this is known to be the cause of a whole
11280 lot of "server hang" problems with Solaris. [David Robinson;
11281 thanks to Merten Schumann for help diagnosing the problem].
11283 Changes with Apache 0.8.9 12 Aug 1995
11285 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
11287 *) Nested includes see environment variables of the including document,
11288 for NCSA bug-compatibility (some sites have standard footer includes
11289 which try to print out the last-modified date). [Eric Hagberg/Robert
11292 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
11293 URI as a CGI script, even if it would have been treated as something
11294 else if requested directly, for NCSA back-compatibility. (Note that
11295 this means that people who know the name of the script can see the
11296 code just by asking for it). [Robert Thau]
11298 *) New version of dbmmanage script included in support directory as
11301 *) Check if scoreboard file couldn't be opened, and say so, rather
11302 then going insane [David Robinson]
11304 *) POST to CGI works on A/UX [Jim Jagielski]
11306 *) AddIcon and AddAlt commands work properly [Rob Hartill]
11308 *) NCSA server push works properly --- the Arena bug compatibility
11309 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
11310 if you still want the workaround). [Rob Hartill]
11312 *) If client didn't submit any Accept-encodings, ignore encodings in
11313 content negotiation. (NB this will all have to be reworked anyway
11314 for the new HTTP draft). [Florent Guillaume]
11316 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
11318 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
11320 *) Give Redirect priority over Alias, for NCSA bug compatibility
11323 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
11324 paralleling earlier bug fix for CGI [David Robinson]
11326 *) If DBM auth is improperly configured, report a server error and don't
11329 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
11330 it seems to work well enough without it (even in a 10 hits/sec
11331 workout), and the overhead for the locking under A/UX is
11332 alarmingly high (though it is very low on other systems).
11333 [Eric Hagberg, Jim Jagielski]
11335 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
11337 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
11338 Behlendorf/Eric Hagberg]
11340 *) More improvements to default Configuration for A/UX [Jim Jagielski]
11342 *) Compiles clean on NEXT [Rob Hartill]
11344 *) Compiles clean on SGI [Robert Thau]
11346 Changes with Apache 0.8.8 08 Aug 1995
11348 *) SunOS library prototypes now never included unless explicitly
11349 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
11350 people using GNU libc on SunOS are screwed by prototypes for the
11353 (Those who wish to compile clean with gcc -Wall on a standard
11354 SunOS setup need the prototypes, and may obtain them using
11355 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
11356 with nonstandard libraries are presumably competent to make their
11359 *) Strips trailing '/' characters off both args to the Alias command,
11360 to make 'Alias /foo/ /bar/' work.
11362 Changes with Apache 0.8.7 03 Aug 1995
11364 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
11365 [reported by David Robinson]
11367 *) Compiles clean on OSF/1 [David Robinson]
11369 *) Added some of the more recent significant changes (AddLanguage stuff,
11370 experimental LogFormat support) to CHANGES file in distribution root
11373 Changes with Apache 0.8.6 02 Aug 1995
11375 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
11376 (If you actually wanted a conditional GET which bypassed the cache, you
11377 couldn't get it). [Reported by Roy Fielding]
11379 *) Properly terminate headers on '304 Not Modified' replies to conditional
11380 GETs --- no browser we can find cares much, but the CERN proxy chokes.
11381 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
11383 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
11385 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
11386 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
11387 and older versions don't set the __SUNPRO_C preprocessor variable). On
11388 all other systems, these are never used anyway. [Reported by Mark Cox].
11390 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
11392 Changes with Apache 0.8.5 01 Aug 1995
11394 *) Added last-minute configurable log experiment, as optional module
11396 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
11397 properly. (One-line fix to http_protocol.c).
11399 *) Work around bogus behavior when reloading from Netscape.
11400 It's Netscape's bug --- for some reason they expect a request with
11401 If-modified-since: to not function as a conditional GET if it also
11402 comes with Pragma: no-cache, which is way out of line with the HTTP
11403 spec (according to Roy Fielding, the redactor).
11405 *) Added parameter to set maximum number of server processes.
11407 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
11410 *) IdentityCheck bugfix [Chuck Murcko].
11412 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
11414 *) More sample config file corrections; add extension to AddType for
11415 *.asis, move AddType generic description to its proper place, and
11416 fix miscellaneous typos. [ Alexei Kosut ]
11418 *) Deleted the *other* reference to the regents from the Berkeley
11419 legal disclaimer (everyplace).
11421 *) Nuked Shambhala name from src/README; had already cleaned it out
11422 of everywhere else.
11424 Changes with Apache 0.8.4
11426 *) Changes to server-pool management parms --- renamed current
11427 StartServers to MinSpareServers, created separate StartServers
11428 parameter which means what it says, and renamed MaxServers to
11429 MaxSpareServers (though the old name still works, for NCSA 1.4
11430 back-compatibility). The old names were generally regarded as
11431 too confusing. Also altered "docs" in sample config files.
11433 *) More improvements to default config files ---
11434 sample directives (commented out) for XBitHack, BindAddress,
11435 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
11436 defaults, AddTypes for send-as-is and imagemap magic types, and
11437 improvements to samples for DirectoryIndex [Alexei Kosut]
11439 *) Yet more improvements to default config files --- changes to
11440 Alexei's sample AddLanguage directives, and sample LanguagePriority
11441 [ Florent Guillaume ]
11443 *) Set config file locations properly if not set in httpd.conf
11446 *) Don't escape URIs in internal redirects multiple times; don't
11447 do that when translating PATH_INFO to PATH_TRANSLATED either.
11450 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
11452 Changes with Apache 0.8.3
11454 *) Edited distribution README to *briefly* summarize installation
11455 procedures, and give a pointer to the INSTALL file in the src/
11458 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
11459 recent NCSA distributions.
11461 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
11462 exist for the same directory, use both and don't segfault. [Reported
11465 *) Proper makefile dependencies [David Robinson]
11467 *) Note (re)starts in error log --- reported by Rob Hartill.
11469 *) Only call no2slash() after get_path_info() has been done, to
11470 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
11471 reported by Andrew Wilson, though this one is probably a real bug]
11473 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
11474 dump core when Referer is not supplied. [Randy Terbush]
11476 *) Lightly edited sample config files to refer people to our documentation
11477 instead of NCSA's, and to list Rob McCool as *original* author (also
11478 deleted his old, and no doubt non-functional email address). Would be
11479 nice to have examples of new features...
11481 Changes with Apache 0.8.2 19 Jul 1995
11483 *) Added AddLanuage code [Florent Guillaume]
11485 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
11487 *) All sorts of problems when MultiViews finds a directory. It would
11488 be nice if mod_dir.c was robust enough to handle that, but for now,
11489 just punt. [reported by Brian Behlendorf]
11491 *) Wait for all children on restart, to make sure that the old socket
11492 is gone and we can reopen it. [reported by Randy Terbush]
11494 *) Imagemap module is enabled in default Configuration
11496 *) RefererLog and UserAgentLog modules properly default the logfile
11499 *) Mark Cox's mod_cookies added to the distribution as an optional
11500 module (commented out in the default Configuration, and noted as
11501 an experiment, along with mod_dld). [Mark Cox]
11503 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
11505 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
11507 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
11509 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
11512 Changes with Apache 0.8.1
11514 *) New imagemap module [Randy Terbush]
11516 *) Replacement referer log module with NCSA-compatible RefererIgnore
11517 [Matthew Gray again]
11519 *) Don't mung directory listings with very long filenames.
11520 [Florent Guillaume]
11522 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
11524 *) New config script. See INSTALL for info. [Robert Thau]
11526 *) Scoreboard mechanism for regulating the number of extant server
11527 processes. MaxServers and StartServers defaults are the same as
11528 for NCSA, but the meanings are slightly different. (Actually,
11529 I should probably lower the MaxServers default to 10).
11531 Before asking for a new connection, each server process checks
11532 the number of other servers which are also waiting for a
11533 connection. If there are more than MaxServers, it quietly dies
11534 off. Conversely, every second, the root, or caretaker, process
11535 looks to see how many servers are waiting for a new connection;
11536 if there are fewer than StartServers, it starts a new one. This
11537 does not depend on the number of server processes already extant.
11538 The accounting is arranged through a "scoreboard" file, named
11539 /tmp/htstatus.*, on which each process has an independent file
11540 descriptor (they need to seek without interference).
11542 The end effect is that MaxServers is the maximum number of
11543 servers on an *inactive* server machine, but more will be forked
11544 off to handle unusually heavy loads (or unusually slow clients);
11545 these will die off when they are no longer needed --- without
11546 reverting to the overhead of full forking operation. There is a
11547 hard maximum of 150 server processes compiled in, largely to
11548 avoid forking out of control and dragging the machine down.
11549 (This is arguably too high).
11551 In my server endurance tests, this mechanism did not appear to
11552 impose any significant overhead, even after I forced it to put the
11553 scoreboard file on a normal filesystem (which might have more
11554 overhead than tmpfs). [Robert Thau]
11556 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
11559 *) Read .htaccess files even in directory with <Directory> section.
11560 (Former incompatibility noted on mailing list, now fixed). [Robert
11563 *) "HEAD /" gives the client a "Bad Request" error message, rather
11564 than trying to send no body *and* no headers. [Cliff Skolnick].
11566 *) Don't produce double error reports for some very obscure cases
11567 mainly involving auth configuration (the "all modules decline to
11568 handle" case which is a sure sign of a server bug in most cases,
11569 but also happens when authentication is badly misconfigured).
11572 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
11573 it's *for*, and this sort of thing really shouldn't be cluttering
11574 up the Makefile). [Robert Thau]
11576 *) Incidental code cleanups in http_main.c --- stop dragging
11577 sa_client around; just declare it where used. [Robert Thau]
11579 *) Another acc-related fix. (It doesn't like const char
11580 in some places...). [Mark Cox]
11582 Changes with Shambhala 0.6.1 13 Jul 1995
11584 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
11585 Also, fixed auth typo in http_protocol.c unmasked by this fix.
11587 *) Compiles clean with acc on SunOS [Paul Sutton]
11589 *) Reordered modules in modules.c so that Redirect takes priority
11590 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
11591 believe it or not, he has an actual site with a ScriptAlias and
11592 a Redirect declared for the *exact same directory*. Even *my*
11593 compatibility fetish wouldn't motivate me to fix this if the fix
11594 required any effort, but it doesn't, so what the hey.
11596 *) Fixed to properly default several server_rec fields for virtual
11597 servers from the corresponding fields in the main server_rec.
11598 [Cliff Skolnick --- 'port' was a particular irritant].
11600 *) No longer kills off nph- child processes before they are
11601 finished sending output. [Matthew Gray]
11603 Changes with Shambhala 0.6.0 10 Jul 1995
11605 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
11606 the connection to the client in an "aborted" state, but otherwise
11607 allow whatever handlers are running to clean up. hard_timeout()s
11608 abort the request in progress completely; anything not tied to some
11609 resource pool cleanup will leak. They're still around because I
11610 haven't yet come up with a more elegant way of handling
11611 timeouts when talking to something that isn't the client. The
11612 default_handler and the dir_handler now use soft timeouts, largely
11613 so I can test the feature. [Robert Thau]
11615 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
11616 the case of log handlers dying prematurely is probably handled VERY
11617 gracelessly at this point, and if the logger stops reading input,
11618 the server will hang. (It is known to correctly restart the
11619 logging process on server restart; this is (should be!) going through
11620 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
11621 script). [Robert Thau]
11623 *) asis files supported (new module). [Robert Thau]
11625 *) IdentityCheck code is compiled in, but has not been tested. (I
11626 don't know anyone who runs identd). [Robert Thau]
11628 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
11629 came in with the request, for NCSA bug-compatibility. [Robert Thau]
11631 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
11633 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
11634 as timeouts are not in scope. [Robert Thau]
11636 *) quoted-string args in config files now handled correctly (doesn't drop
11637 the last character). [Robert Thau; reported by Randy Terbush]
11639 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
11640 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
11642 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
11643 default default type); the former default default behavior when all
11644 type-checkers defaulted had been a core dump. [Paul Sutton]
11646 *) Copy filenames out of the struct dirent when indexing
11647 directories. (On Linux, readdir() returns a pointer to the same
11648 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
11650 Changes with Shambhala 0.5.3 [not released]
11652 *) Default response handler notes "file not found" in the error log,
11653 if the file was not found. [Cliff Skolnick].
11655 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
11656 code no longer sets up bogus PATH_INFO which fakes out the directory
11657 handler). [Cliff Skolnick]
11659 Changes with Shambhala 0.5.2 06 Jul 1995
11661 *) Changes to http_main.c --- root server no longer plays silly
11662 games with SIGCHLD, and so now detects and replaces dying
11663 children. Child processes just die on SIGTERM, without taking
11664 the whole process group with them. Potential problem --- if any
11665 child process refuses to die, we hang in restart.
11666 MaxRequestsPerChild may still not work, but it certainly works
11667 better than it did before this! [Robert Thau]
11669 *) mod_dir.c bug fixes: ReadmeName and HeaderName
11670 work (or work better, at least); over-long description lines
11671 properly terminated. [Mark Cox]
11673 *) http_request.c now calls unescape_url() more places where it
11674 should [Paul Sutton].
11676 *) More directory handling bugs (reported by Cox)
11677 Parent Directory link is now set correctly. [Robert Thau]
11679 Changes with Shambhala 0.5.1 04 Jul 1995
11681 *) Generalized cleanup interface in alloc.c --- any function can be
11682 registered with alloc.c as a cleanup for a resource pool;
11683 tracking of files and file descriptors has been reimplemented in
11684 terms of this interface, so I can give it some sort of a test.
11687 *) More changes in alloc.c --- new cleanup_for_exec() function,
11688 which tracks down and closes all file descriptors which have been
11689 registered with the alloc.c machinery before the server exec()s a
11690 child process for CGI or <!--#exec-->. CGI children now get
11691 started with exactly three file descriptors open. Hopefully,
11692 this cures the problem Rob H. was having with overly persistent
11693 CGI connections. [Robert Thau]
11695 *) Mutual exclusion around the accept() in child_main() --- this is
11696 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
11697 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
11698 This uses fcntl(F_SETLK,...) on the error log descriptor because
11699 flock() on that descriptor won't work on systems which have BSD
11700 flock() semantics, including (I think) Linux 1.3 and Solaris.
11702 This does work on SunOS (when the server is idle, only one
11703 process in the pool is waiting on accept()); it *ought* to work
11704 on the other systems. [Robert Thau]
11706 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
11708 *) sizeof(*sa_client) bugfix from [Rob Hartill]
11710 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
11712 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
11713 be unnecessary if I go to the revised timeout-handling scheme).
11716 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
11717 string) even if none came in with the request. [Robert Thau]
11719 *) CHANGES file added to distribution ;-).
11721 Changes with Shambhala 0.4.5
11723 *) mod_dld --- early dynamic loading support [rst]
11724 *) Add wildcard content handlers for XBITHACK; default_hander now
11725 invoked with that mechanism (as a handler hanging off mod_core) [rst]
11726 *) XBITHACK supported as a wildcard content-handler, and
11727 configurable at run-time (not just at compile time, as in the
11728 "patchy server" releases) [rst]
11730 Changes with Shambhala 0.4.4 30 Jun 1995
11732 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
11733 *) Handle Addtype x/y .z [rst, reported by Cox]
11735 Changes with Shambhala 0.4.3
11737 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
11738 synonymous [rst, terbush]
11740 Changes with Shambhala 0.4.1 28 Jun 1995
11742 *) First-cut virtual host implementation; some refit in the config
11743 reading code, and log management, was necessary to support this [rst]
11744 *) Sub-pool machinery, originally added to avoid excessive storage
11745 allocation on listings of large directories (which turned out to
11746 be the problem that the 0.3 storage accounting was added to
11747 find). Subrequests and mod_dir changed to use subpools. [rst]
11748 *) More memory debugging --- free list consistency checks. [rst]
11749 *) Added err_headers to request_rec, with support elsewhere [rst]
11750 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
11752 Changes with Shambhala 0.3 19 Jun 1995
11754 *) Switch ONE_PROCESS to a runtime command-line option (-X)
11755 *) Don't compile in mod_ai_backcompat by default
11756 *) Switch name of server from Apache to Shambhala in Makefile
11757 *) Add some accounting routines to track memory usage in the pools,
11760 Changes with Shambhala 0.2
11762 *) Set DOCUMENT_ROOT CGI variable
11763 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
11764 *) Add critical section protection to handling of cleanup structures
11766 *) Significant code reorg within the server core to group related
11767 functions together [rst]
11768 *) Correctly handle clients that hang up before sending any request
11770 *) Replace dying child processes. [rst]
11772 Changes with Shambhala 0.1 12 Jun 1995
11774 Major rewrite of the pre-existing "patchy server" codebase, by
11775 Robert Thau (rst). Significant portions of the server code, such
11776 as configuration-file handling and HTTP authentication support,
11777 were ripped out and rewritten from scratch. Code that was not
11778 completely rewritten was significantly altered.
11780 Major changes with this release include:
11782 *) Introduction of the module API; in request handling, the central
11783 machinery just dispatches to various modules, which actually do
11784 most of the work. Configuration handling is similar --- modules
11785 declare their own commands, and the central machinery just
11786 dispatches to them.
11788 API features from shambhala/0.1 were substantially unchanged in
11789 Apache 1.0 and 1.1. (1.0 API features not yet present in this
11790 release, such as wildcard handlers and subpools, were added in
11791 subsequent Shambhala releases, and were also generally rst's
11794 *) This release included the following modules:
11796 mod_access (access control --- allow and deny directives),
11797 mod_alias (Alias and Redirect commands),
11798 mod_auth (straight HTTP authentication, based on flat-files)
11799 mod_auth_dbm (same, with dbm files)
11800 mod_cgi (CGI scripts and, in this release, ScriptAlias)
11801 mod_common_log (CLF access logs; later renamed mod_log_common)
11802 mod_dir (directory indexing)
11803 mod_include (server-side includes)
11804 mod_mime (AddType directives)
11805 mod_negotiation (content negotiation)
11806 mod_userdir (support for users' public_html directories)
11808 It also included a mod_ai_backcompat, which was a private hack
11809 for back-compatibility with rst's own AI-lab servers.
11811 All of these modules were substantially complete, and functional
11812 or nearly so (a few, which implemented features not in use at
11813 Thau's site, required patches of a few lines).
11815 *) sub-request machinery, to allow modules to determine how other
11816 modules would assign MIME types to a given file, or optionally
11817 serve its content (this is heavily used by mod_dir, mod_include
11818 and mod_negotiation).
11820 *) Resource pool system for keeping track of memory allocated and
11821 files opened in service of a particular request. Much of the
11822 code in the modules (when they weren't rewrites) was adjusted to
11823 replace a pervasive convention of using fixed-size buffers on
11824 the stack with an equally pervasive convention of using memory
11825 allocated with palloc().
11827 *) Reorganization of data structures associated with a given
11828 request to eliminate use of global variables and the troublesome
11829 unmunge_name function (used in NCSA and early Apache releases to
11830 attempt to determine the URI which mapped to a given filename
11831 --- a difficult proposition, given that it is easy to produce
11832 setups in which multiple URIs map to the same file).
11834 *) Source files renamed and rearranged
11836 *) Very simple pre-forking behavior --- parent process forked off a
11837 fixed number of children, and then just waited for SIGHUP.
11839 *) Other more minor changes too numerous to list.
11841 This release included modified versions of a lot of code from the
11842 Apache 0.6.4 public release, plus an early pre-forking patch
11843 codeveloped by Robert Thau and Rob Hartill.
11845 Changes with Apache 0.7.3 20 Jun 1995
11847 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
11848 were incorporated by Rob Hartill on the main branch while Robert Thau
11849 worked on the Shambhala rewrite above. Most were merged into the
11850 Shambala architecture after Apache 0.8.0.
11852 Changes with Apache 0.6.4 13 May 1995
11854 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
11857 Changes with Apache 0.5.1 10 Apr 1995
11859 Changes with Apache 0.4 02 Apr 1995
11861 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
11864 Changes with Apache 0.3 24 Mar 1995
11866 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
11869 Changes with Apache 0.2 18 Mar 1995
11871 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
11872 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
11873 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
