2 Changes with Apache 2.0.40
4 *) Improve ap_get_client_block implementation by using APR-util brigade
5 helper functions and relying on current filter assumptions.
8 Changes with Apache 2.0.39
10 *) Fixed a build problem in htpasswd.c on Win32.
11 [Guenter Knauf <eflash@gmx.net>, Cliff Woolley]
13 Changes with Apache 2.0.38
15 *) Rewrite htpasswd to use APR. The removes the annoying warning about
16 tmpnam being unsafe. [Ryan Bloom]
18 *) We must set the MIME-type for .shtml files to text/html if we want them
19 to be parsed for SSI tags. Add the config for that to the default
20 config file so that it is easier to enable .shtml parsing.
21 [Dave Dyer <ddyer@real-me.net>]
23 *) Fixed a problem with 'make install' on ReliantUnix.
24 [Jean-frederic Clere <jfrederic.clere@fujitsu-siemens.com>]
26 *) Make the default_handler catch all requests that aren't served by
27 another handler. This also gets us to return a 404 if a directory
28 is requested, there is no DirectoryIndex, and mod_autoindex isn't
29 loaded. [Justin Erenkrantz]
31 *) Fixed the handling of nested if-statements in shtml files.
34 *) Allow 'make install DESTDIR=/path'. This allows packagers to install
35 into a directory different from the one that was configured. This
36 also mirrors the root= feature from 1.3. We cannot use prefix=,
37 because both APR and APR-util resolve their installation paths at
38 configuration time. This means that there is no variable prefix
39 to replace. [Andreas Hasenack <andreas@netbank.com.br>]
41 *) AIX 4.3.2 and above: Define SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
42 These levels of AIX don't have a thundering herd problem with
43 accept(). [Jeff Trawick]
45 *) prefork MPM: Ignore mutex errors during graceful restart. For
46 certain types of mutexes (particularly SysV semaphores), we
47 should expect to occasionally fail to obtain or release the
48 mutex during restart processing. [Jeff Trawick]
50 *) Fix install-bindist.sh so that it finds any perl instead of just
51 early perl 5.x versions. This is consistent with a build/install
52 from source, and it allows the perl scripts installed by a bindist
53 to work on systems with perl 5.6. [Jeff Trawick]
55 *) Fix apxs so that the makefile created by "apxs -g" works on AIX and
56 Tru64 (and probably some other platforms). [Jeff Trawick]
58 *) Allow CGI scripts to return their Content-Length. This also fixes a
59 hang on HEAD requests seen on certain platforms (such as FreeBSD).
62 *) Added log rotation based on file size to the RotateLog support
63 utility. [Brad Nicholes]
65 *) Fix some casting in mod_rewrite which broke random maps.
66 PR 9770 [Allan Edwards, Greg Ames, Jeff Trawick]
68 Changes with Apache 2.0.37
70 *) allow POST method over SSL when per-directory client cert
71 authentication is used with 'SSLOptions +OptRenegotiate' enabled
72 and a client cert was found in the ssl session cache.
74 *) 'SSLOptions +OptRengotiate' will use client cert in from the ssl
75 session cache when there is no cert chain in the cache. prior to
76 the fix this situation would result in a FORBIDDEN response and
77 error message "Cannot find peer certificate chain"
80 *) ap_finalize_sub_req_protocol() shouldn't send an EOS bucket if
81 one was already sent. PR 9644 [Jeff Trawick]
83 *) Fix the display of the default name for the mime types config
84 file. PR 9729 [Matthew Brecknell <mbrecknell@orchestream.com>]
86 *) Fix the working directory *for WinNT/2K/XP services only* to
87 change to the Apache directory (one level above the location
88 of Apache.exe, in the case that Apache.exe resides in bin/.)
89 Solves the case of ServerRoot /foo paths where /foo was not
90 on the same drive as /winnt/system32. [William Rowe]
92 *) Make 2.0's "AcceptMutex" startup message now "completely"
93 match how 1.3 does it. [Jim Jagielski]
95 *) Implement a fixed size memory cache using a priority queue
98 *) Fix apxs to allow "apxs -q installbuilddir" and to allow
99 querying certain other variables from config_vars.mk. PR 9316
102 *) Added the "detached" attribute to the cgi_exec_info_t internals
103 so that Win32 and Netware won't create a new window or console
104 for each CGI invoked. PR 8387
105 [Brad Nicholes, William Rowe]
107 *) Consolidated the command line parameters and attributes that are
108 manipulated by the optional function ap_cgi_build_command() in
109 mod_cgi into a single structure.
112 *) Get rid of uninitialized value errors with "apxs -q" on certain
113 variables. [Stas Bekman <stas@stason.org>]
115 *) Fix apxs to allow it to work when the build directory is somewhere
116 besides server-root/build. PR 8453
117 [Jeff Trawick and a host of others]
119 *) Allow ap_discard_request_body to be called multiple times in the
120 same request. Essentially, ap_http_filter keeps track of whether
121 it has sent an EOS bucket up the stack, if so, it will only ever
122 send an EOS bucket for this request.
123 [Ryan Bloom, Justin Erenkrantz, Greg Stein]
125 *) Remove all special mod_ssl URIs. This also fixes the bug where
126 redirecting (.*) will allow an SSL protected page to be viewed
127 without SSL. [Ryan Bloom]
129 *) Fix the binary build install script so that the build logic
130 created by "apxs -g" will work when the user has a binary
131 build. [Jeff Trawick]
133 *) Allow instdso.sh to work with full paths to the shared module.
136 *) NetWare: Enabled CGI functionality and added mod_cgi as a built
137 in module for NetWare [Brad Nicholes]
139 *) Changed cgi and piped log behavior to accept 65536 characters
140 on Win32 (matching Linux) before deadlocking between outputing
141 client stdin, slurping the output from stdout and then the stderr
142 stream. PR 8179 [William Rowe]
144 *) Fixed Win32 wintty.exe support to assure the window title is valid.
145 Elimiates possible gpfault or garbage title without the -t option.
148 *) Rewrite mod_cgi, mod_cgid, and mod_proxy input handling to use
149 brigades and input filters. [Justin Erenkrantz]
151 *) Allow ap_http_filter (HTTP_IN) to return EOS when there is no request
152 body. [Justin Erenkrantz]
154 *) NetWare: Piping log entries through RotateLogs using the
155 CustomLogs directive is finally supported now that we have
156 the pipes and spawning functionality working.
159 *) Detect overflow when reading the hex bytes forming a chunk line.
162 *) Allow RewriteMap prg:'s to take command-line arguments. PR 8464.
163 [James Tait <JTait@wyrddreams.demon.co.uk>]
165 *) Correctly return 413 when an invalid chunk size is given on
166 input. Also modify ap_discard_request_body to not do anything
167 on sub-requests or when the connection will be dropped.
170 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
173 *) Ensure that apr_brigade_write() flushes in all of the cases that
174 it should to avoid conditions in some modules that could cause
175 large amounts of data to be buffered. [Cliff Woolley]
177 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
178 stripping the content_type from cached responses.
181 *) apachectl passes through any httpd options. Note: apachectl
182 should be used in preference to httpd since it ensures that any
183 appropriate environment variables have been set up.
186 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.
187 PR 7810 [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]
189 *) Fix suexec execution of CGI scripts from mod_include.
190 PR 7791, 8291 [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]
192 *) Fix segfaults at startup on some platforms when mod_auth_digest,
193 mod_suexec, or mod_ssl were used as DSO's due to the way they
194 were tracking the current init phase since DSO's get completely
195 unloaded and reloaded between phases. PR 9413.
196 [Tsuyoshi Sasamoto <nazonazo@super.win.ne.jp>, Brad Nicholes]
198 *) Fix mod_include's handling of regular expressions in
199 "<!--#if" directives [Julius Gawlas <julius_gawlas@hp.com>]
201 *) Fix the worker MPM deadlock problem [Brian Pane]
203 *) Modify the module documentation to allow for translations.
204 [Yoshiki Hayashi, Joshua Slive]
206 *) Fix a file permissions problem which prevented mod_disk_cache
207 from working on Unix. [Jeff Trawick]
209 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix
210 MPMs. These have semantics very similar to the old apachectl
211 commands of the same name. [Justin Erenkrantz, Jeff Trawick]
213 *) Make sure that the runtime dir is created by make install.
214 PR 9233. [Jeff Trawick]
216 *) Fix an unusual set of ./configure arguments that could cause
217 mod_http to be built as a DSO, which it currently doesn't
219 [Cliff Woolley, Robin Johnson <robbat2@orbis-terrarum.net>]
221 *) Win32: Fix bug in apr_sendfile() that caused incorrect operation
222 of the %X, %b and %B logformat options. PR 8253, 8996.
225 *) If content-encoding is already present, do not run deflate (PR 9222)
226 [Kazuhisa ASADA <kaz@asada.sytes.net>]
228 *) The APLOG_NOERRNO flag to ap_log_[r]error() is now deprecated.
229 It is currently ignored and it will be removed in a future release
230 of Apache. [Jeff Trawick]
232 *) Removed documentation references to the no-longer-supported
233 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
234 certificates, if truly desired, can be generated using openssl
235 commands. PR 8724. [Cliff Woolley]
237 *) Remove SSLLog and SSLLogLevel directives in favor of having
238 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
240 *) OS/390: LIBPATH no longer has to be manually uncommented in
241 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
243 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
244 may now be specified to the <File/Directory > container, rather
245 than by vhost. [William Rowe]
247 *) mod_isapi: Experimental support for faux async support for ISAPI
248 modules. [William Rowe]
250 *) mod_isapi: Major refactoring of the code to rely on apr internals
251 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
252 symbol definitions.) [William Rowe]
254 *) mod_isapi: Fixed the return string length from GetServerVariable
255 callback, it was not including the trailing null in the consumed
256 buffer size. This was particularly bad for Delphi 6.0 users.
257 PR 8934 [Sebastian Hantsch <sebastian.hantsch@gmx.de>]
259 *) Fixed Win32 builds for Microsoft VisualStudio 7.0 (.net).
262 *) Make apxs look in the correct directory for envvars. It was
263 broken when sbindir != bindir. PR 8869
264 [Andreas Sundström <sunkan@zappa.cx>]
266 *) Fix mod_deflate corruption when using multiple buckets. PR 9014.
267 [Asada Kazuhisa <kaz@asada.sytes.net>]
269 *) Performance enhancements for access logger when using
270 default timestamp formatting [Brian Pane]
272 *) Added EnableMMAP config directive to enable the server
273 administrator to disable memory-mapping of delivered files
274 on a per-directory basis. [Brian Pane]
276 *) Performance enhancements for mod_setenvif [Brian Pane]
278 *) Fix a mod_ssl build problem on OS/390. [Jeff Trawick]
280 *) Fixed If-Modified-Since on Win32, which would give false positives
281 because of the sub-second resolution of file timestamps on that
282 platform. [Cliff Woolley]
284 *) Reverse the hook ordering for mod_userdir and mod_alias so
285 that Alias/ScriptAlias will override Userdir. PR 8841
288 *) Move mod_deflate out of experimental and into filters.
291 *) Get proxy CONNECT basically working. [Jeff Trawick]

297 *) Fix byterange requests from returning 416 when using dynamic data
298 (such as filters like mod_include). [Justin Erenkrantz]
300 *) Allow mod_rewrite's set of "int:" internal RewriteMap functions
301 to be extended by third-party modules via an optional function.

310 *) Fix generated httpd.conf to respect layout for LoadModule lines.
311 PR 8170. [Thom May <thom@planetarytramp.net>]
313 *) Win32: During a graceful restart, threads in the new process
314 were accessing scoreboard slots still in use by active threads in
315 the the old process. [Bill Stoddard]
317 Changes with Apache 2.0.36
319 *) Fix some minor formatting issues with ab. Part of this is
320 in reference to PR 8544, the rest I noticed while testing
321 the PR fix. [Paul J. Reder]
323 *) Fix a case where an invalid pass phrase is entered and an
324 error message is given, but the prompt is not shown again.
325 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
327 *) Close sockets on worker MPM when doing a graceless restart.
330 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
331 as the session id context rather that a MD5 hash of that vhost ID,
332 because it caused very long vhost id's to be unusable with mod_ssl.
333 PR 8572. [Cliff Woolley]
335 *) Fix the link to the description of the CoredumpDirectory
336 directive in the server-wide document. PR 8643. [Jeff Trawick]
338 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
340 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
341 - Avoid SIGBUS on sparc machines with SHMCB session caches
342 - Allow whitespace between the pipe and the name of the
343 program in SSLLog "| /path/to/program". [Cliff Woolley]
345 *) Introduce mod_ext_filter and mod_deflate experimental modules
346 to the Win32 build (zlib sources must be in srclib\zlib.)
349 *) Changes to the worker MPM's queue management and thread
350 synchronization code to reduce mutex contention [Brian Pane]
352 *) Don't install *.in configuration files since we already install
353 *-std.conf files. [Aaron Bannert]
355 *) Many improvements to the threadpool MPM. [Aaron Bannert]
357 *) Fix subreqs that are promoted via fast_redirect from having invalid
358 frec->r structures. This would cause subtle errors later on in
359 request processing such as seen in PR 7966. [Justin Erenkrantz]
361 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
363 *) Modify the worker MPM to not accept() new connections until
364 there is an available worker thread. This prevents queued
365 connections from starving for processing time while long-running
366 connections were hogging all the available threads. [Aaron Bannert]
368 *) Convert the worker MPM's fdqueue from a LIFO back into a FIFO.
371 *) Get basic HTTP proxy working on EBCDIC machines. [Jeff Trawick]
373 *) Allow mod_unique_id to work on systems with no IPv4 address
374 corresponding to their host name. [Jeff Trawick]
376 *) Fix suexec behavior with user directories. PR 7810.

379 *) Reject a blank UserDir directive since it is ambiguous. PR 8472.
382 *) Make mod_mime use case-insensitive matching when examining
383 extensions on all platforms. PR 8223. [Justin Erenkrantz]
385 *) Add an intelligent error message should no proxy submodules be
386 valid to handle a request. PR 8407 [Graham Leggett]
388 *) Major improvements in concurrent processing for AB by enabling
389 non-blocking connect()s and preventing APR from doing blocking
390 read()s. Also implement fatal error checking for apr_recv().
393 *) Fix Win32 NTFS Junctions (symlinks). PR 8014 [William Rowe]
395 *) Fix Win32 'short name' aliases in httpd.conf directives.

398 *) Fix generation of default httpd.conf when the layout paths are
399 disjoint. PR 7979, 8227. [Justin Erenkrantz]
401 *) Swap downgrade-1.0 and force-response-1.0 conditional checks so
402 that downgraded responses can have force-response. PR 8357.
405 *) Fix perchild MPM so that it can be configured with the move to the
406 experimental directory. [Scott Lamb <slamb@slamb.org>]
408 *) Fix perchild MPM so that it uses ap_gname2id for groups instead of
409 ap_uname2id. [Scott Lamb <slamb@slamb.org>]
411 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
413 *) [Security] Added the APLOG_TOCLIENT flag to ap_log_rerror() to
414 explicitly tell the server that warning messages should be sent
415 to the client in addition to being recorded in the error log.
416 Prior to this change, ap_log_rerror() always sent warning
417 messages to the client. In one case, a faulty CGI script caused
418 the server to send a warning message to the client that contained
419 the full path to the CGI script. This could be considered a
420 minor security exposure. [Bill Stoddard]
422 *) mod_autoindex output when SuppressRules was specified would
423 omit the first carriage return so the first item in the list
424 would appear to the right of the column headings instead of
425 underneath them. PR 8016 [David Shane Holden <dpejesh@yahoo.com>]
427 *) Moved the call to apr_mmap_dup outside the error branch so
428 that it would actually get called. This fixes a core dump
429 at init everytime you use the MMapFile directive. PR 8314
432 *) Trigger an error when a LoadModule directive attempts to
433 load a module which is built-in. This is a common error when
434 switching from a DSO build to a static build. [Jeff Trawick]
436 *) Change instdso.sh to use libtool --install everywhere and then
437 clean up some stray files and symlinks that libtool leaves around
438 on some platforms. This gets subversion building properly since
439 it needed a re-link to be performed by libtool at install time,
440 and the old instdso.sh logic to simply cp the DSO didn't handle
441 that requirement. [Sander Striker]
443 *) Allow VPATH builds to succeed when configured from an empty
444 directory. [Thom May <thom@planetarytramp.net>]
446 *) Fix 'control reaches end of non-void function' warning in
447 server/log.c. [Ben Collins-Sussman <sussman@collab.net>]
449 *) Perchild MPM is now correctly deemed as experimental and is now
450 located in server/mpm/experimental. [Justin Erenkrantz]
452 *) Fix segfault in mod_mem_cache when garabge collecting an expired
453 cache entry. [Bill Stoddard]
455 *) Introduced -E startup_logfile_name option to httpd to allow admins
456 to begin logging errors immediately. This provides Win32 users
457 an alternative to sending startup errors to the event viewer, and
458 allows other daemon tool authors an alternative to logging to stderr.
461 *) Fix subreqs with non-defined Content-Types being served improperly.
464 *) Merge in latest GNU config.guess and config.sub files. PR 7818.
467 *) Move 100 - Continue support to the HTTP_IN filter so that filters

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

547 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
548 cause the Apache parent process to run in the foreground (similar to
549 -DNO_DETACH except that it doesn't switch session ids).
552 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
553 for those platforms that support it. If using the default
554 implementation, this is between pthread and sysvsem in priority.
555 This implies it's the new default for Darwin. [Jim Jagielski]
557 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
558 environment variables in the envvars file. [Jeff Trawick]
560 *) worker MPM: Don't create a listener thread until we have a worker
561 thread. Otherwise, in situations where we'll have to wait a while
562 to take over scoreboard slots from a previous generation, we'll be
563 accepting connections we can't process yet. [Jeff Trawick]
565 *) Allow worker MPM to build on systems without pthread_kill().

613 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
615 *) Add a new parameter to the quick_handler hook to instruct
616 quick handlers to optionally do a lookup rather than actually
617 serve content. This is the first of several changes required fix
618 several problems with how quick handlers work with subrequests.
621 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
623 *) [APR-related] The ordering of the default accept mutex method has
624 been changed to better match what's done in Apache 1.3. The ordering
625 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
628 *) Ensure that the build/ directory is created when using VPATH.
631 *) Add some popular types to the mime magic file. PR 7730.
632 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
634 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
636 *) When a proxied site was being served, Apache was replacing
637 the original site Server header with it's own, which is not
638 allowed by RFC2616. Fixed. [Graham Leggett]
640 *) Fix a mod_cgid problem that left daemon processes stranded
641 in some server restart scenarios. [Jeff Trawick]
643 *) Added exp_foo and rel_foo variables to config_vars.mk for
644 all Apache and Autoconf path variables (like --sysconfdir,
645 --sbindir, etc). exp_foo is the "expanded" version, which means
646 that all internal variable references have been interpolated.
647 rel_foo is the same as $exp_foo, only relative to $prefix if they
648 share a common path. [Aaron Bannert]
650 *) Fix some restart/terminate problems in the worker MPM. Don't
651 drop connections during graceful restart. [Jeff Trawick]
653 *) Change the header merging behaviour in proxy, as some headers
654 (like Set-Cookie) cannot be unmerged due to stray commas in
655 dates. [Graham Leggett]
657 *) Be more vocal about what AcceptMutex values we allow, to make
658 us closer to how 1.3 does it. [Jim Jagielski]
660 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
663 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
665 *) Add accessor function to set r->content_type. From now on,
666 ap_rset_content_type() should be used to set r->content_type.
667 This change is required to properly implement the
668 AddOutputFilterByType configuration directive.
669 [Bill Stoddard, Sander Striker, Ryan Bloom]
671 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
672 RFC 3253. Improved the method name/number mapping functions.
675 *) remove sock_enable_linger from connection.c [Ian Holsman]
677 *) Fix for virtual host processing where the requested hostname
678 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
680 *) mod_dav's APIs for REPORT response handling was changed so that
681 providers can generate the content directly into the output filter
682 stack, rather than buffering the response into memory. [Greg Stein]
684 *) Fix a hang condition with graceful restart and prefork MPM
685 in the situation where MaxClients is very high but
686 much fewer servers are actually started at the time of the
687 restart. [Jeff Trawick]
689 *) Small performance fixes for mod_include [Brian Pane]
691 *) Performance improvement for the error logger [Brian Pane]
693 *) Change configure so that Solaris 8 and above have
694 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
695 according to sun people solaris 8+ doesn't have a thundering
696 herd problem [Ian Holsman]
698 *) Allow URIs specifying CGI scripts to include '/' at the end
699 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
700 which ignore '/' at the end of the names of non-directories).
701 PR 10138 [Jeff Trawick]
703 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
704 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
706 *) Fix apxs -g handling. Move config_vars.mk from the top build
707 directory to the build directory. PR 10163 [Jeff Trawick]
709 *) Fix some mod_include problems which broke evaluation of some
710 expressions. PR 10108 [Jeff Trawick]
712 *) Fix the calculation of request time in mod_status. [Stas Bekman]
714 *) Fix the calculation of thread_num in the worker score structure.
717 *) Use apr_atomic operations in managing the mod_mem_cache
718 cache_objects for SMP scalability. (see USE_ATOMICS
719 preprocessor directive in mod_file_cache)
722 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
723 preprocessor directive in mod_file_cache)
726 *) Implement prototype mod_disk_cache for use with mod_cache.
729 *) Add a missing manualdir entry in the Debian config.layout.
730 [Thom May <thom@planetarytramp.net>]
732 *) Stop installing libtool for APR and tell APR where it should place
733 its copy of libtool (via our installbuildpath layout variable).
736 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
737 when reading from a remote HTTP server in proxy. [Graham Leggett]
739 *) Modify receive/send loop in proxy_http and proxy_ftp so that
740 should it be necessary, the remote server socket is closed before
741 transmitting the last buffer (set by ProxyIOBufferSize) to the
742 client. This prevents the backend server from being forced to hang
743 around while the last few bytes are transmitted to a slow client.
744 Fix the case where no error checking was performed on the final
745 brigade in the loop. [Graham Leggett]
747 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
748 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
749 hours. [Graham Leggett, Bill Stoddard]
751 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
752 for a undefined variable. [Ian Holsman]
754 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
755 when we can't get a socket in the specified address family. We may
756 have gotten back an IPv6 address first and yet our system is not
757 configured to allow IPv6 sockets. [Jeff Trawick]
759 *) Be more careful about recursively removing CVS directories. Make
760 sure that we aren't cd'ing to their home directory first. PR: 9993

763 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
764 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
765 Thom May <thom@planetarytramp.net>]
767 *) Rename the filter ordering priorities. The recent filtering fixes
768 have showcased problems with their usage. Therefore, we need to
769 rename them to increase the clarity. (CONTENT->RESOURCE,
770 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
772 Changes with Apache 2.0.33
774 *) Fix a problem in the new --enable-layout functionality where
775 it wouldn't allow overrides from variables like --prefix,
776 --bindir, etc. [Thom May <thom@planetarytramp.net>]
778 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
779 no longer hangs around waiting for the socket to close before
780 returning exhaustive data. [Aaron Bannert]
782 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
783 [Thom May <thom@planetarytramp.net>]
785 *) Change mod_ssl to always do a full startup/teardown on restarts.
786 this allows mod_ssl to be added to a server that is already
787 running and makes it possible to add/change certs/keys after the
788 server has been started. [Doug MacEachern]
790 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
791 This pipe must be a bidirectional 'console' style relay, which
792 mod_ssl prints all prompts to the pipe's stdin, and reads the
793 passphrases from the pipe's stdout. [William Rowe]
795 *) Fix bug where --sysconfdir and --localstatedir were being
796 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
799 *) Fix --enable-layout to work again. Caution: When specifying
800 --enable-layout, common arguments like --prefix, --exec-prefix,
801 etc. will be ignored and the settings from the layout will be
802 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
805 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
806 regex pattern matching for the determination of which requests
807 to use the remote proxy for. [Jim Jagielski]
809 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
811 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
812 cruft in piped logs and rewritemap child processes.
815 *) All instances of apr_lock_t have been removed and converted
816 to one of the following new lock APIs: apr_thread_mutex.h,
817 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
818 use the apr_lock.h API, as the old API will soon be deprecated.
821 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
822 [Ralf S. Engelschall, Cliff Woolley]
824 *) mod-include: make it handle flush'es and fix the 'false-alarm'
825 [Justin Erenkrantz, Brian Pane, Ian Holsman]
827 *) ap_get_*_filter_handle() functions to allow 3rd party modules
828 to lookup filter handles so they can bypass the filter name
829 lookup when adding filters to a request (via ap_add_*_filter_handle())
830 [Ryan Morgan <rmorgan@covalent.net>]
832 *) Fix for multiple file buckets on Win32, where the first file
833 bucket would cause the immediate closure of the socket on any
834 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
836 *) Correct Win32 failure of mmap of a segment beyond start of the
837 file; fixes large SSL and similar transfers. [William Rowe]
840 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
841 multi-process mode to not "daemonize" while detaching from the
842 controlling terminal. This is necessary for Apache to work with
843 process-management tools like AIX's "System Resource Controller"
844 as well as Dan Bernstein's "daemontools".
845 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
847 *) Convert mod_auth_digest to use the new apr_global_mutex_t
848 type. [Aaron Bannert]
850 *) fix bug in mod-include where it wouldn't send a unmatched
851 part if it was at the end of a bucket [Ian Holsman]
853 *) worker MPM: Improve logging of errors with the interface between
854 the listener thread and worker threads. [Jeff Trawick]
856 *) Some browsers ignore cookies that have been merged into a
857 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
858 are now unmerged in the http proxy before being sent to the
859 client. [Graham Leggett]
861 *) Fix a problem with proxy where each entry of a duplicated
862 header such as Set-Cookie would overwrite and obliterate the
863 previous value of the header, resulting in multiple header
864 values (like cookies) going missing.
865 [Graham Leggett, Joshua Slive]
867 *) Add the server-limit and thread-limit values to the scoreboard
868 for the sake of third-party applications.
869 [Adam Sussman <myddryn@vishnu.vidya.com>]
871 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
873 *) OS/390: Get make install to properly copy DSO modules.
876 *) Win32: Fix bug in mod_status with displaying "Restart Time"
880 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
882 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
884 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
885 [David MacKenzie <djm@pix.net>]
887 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
888 [David MacKenzie <djm@pix.net>]
890 *) Fix segfault and display error when SSLMutex file can not be
891 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
893 *) Add reference counting to mod_mem_cache cache objects to
894 better manage removing objects from the cache.
897 *) Change the verbage on the ScoreBoardFile in our default configs.
898 Also change the default to be commented out (unspecified) so we
899 get anonymous shared memory by default. [Aaron Bannert]
901 *) Implement new ScoreBoardFile directive logic. This affects how
902 we create the scoreboard's shared memory segment. If the directive
903 is present, a name-based segment is created. If the directive is
904 not present, first an anonymous segment is created, and if that
905 fails, a name-based segment is created from a file of the name
906 DEFAULT_SCOREBOARD. This gives third-party applications the
907 ability to access our scoreboard. [Aaron Bannert]
909 *) Allow mod_deflate to work with non-GET requests and properly send
910 Content-Lengths. [Sander Striker <striker@apache.org>]
912 *) Fix ap_directory_merge() to correctly merge configs when there is
913 no <Directory /> block. [Justin Erenkrantz, William Rowe]
915 *) Remove spurious debug messsages that are normal under HTTP
916 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
918 *) Fix a bug in mod_cgid that would prevent proper shutdown death
919 of the cgid process. [Aaron Bannert]
921 *) Add signal handling back in to the worker MPM for the one_process
922 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
924 *) Performance: Reuse per-connection transaction pools in the
925 worker MPM, rather than destroying and recreating them. [Brian Pane]
927 *) Remove all signals from the worker MPM's child process. Instead,
928 the parent uses the Pipe of Death for all communication with the
929 child processes. [Ryan Bloom]
931 Changes with Apache 2.0.32
933 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
934 default if the directive is not specified. This mirrors older
935 behavior without changes to the httpd.conf. [William Rowe]
937 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
938 the service, mpm and logging code, and bugs in apr_file_open_stderr
939 and apr_file_dup2 functions. Win2K/XP services have no handles
940 associated for stdin/out/err, which caused unpredictable behavior
941 in the prior release. [William Rowe, Bill Stoddard]
943 *) Win32: simplify the Application Event Log messages, since there isn't
944 likely to be 'more information in the error log' before an error log
945 has been opened. [William Rowe]
947 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
948 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
950 *) Win32: apache -k shutdown now behaves like apache -k stop.
953 *) Fix prefork to not kill the parent if a child hits a resource shortage
954 on accept(). [Greg Ames]
956 *) Fix seg faults that occur when what should be the httpd request line
957 starts with \r\n followed by garbage. [Greg Ames]
959 *) Allow statically linked support binaries with the new
960 --enable-static-support flag, and enable this behavior in
961 the binbuild script. Also add a new --enable-static-htdbm
962 flag. [Aaron Bannert]
964 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
965 do only one stat() call when generating the directory listings.
968 *) Fix resolve_symlink to save the original symlink name if known.
971 *) Be a bit more sane with regard to CanonicalNames. If the user has
972 specified they want to use the CanonicalName, but they have not
973 configured a port with the ServerName, then use the same port that
974 the original request used. [Ryan Bloom and Ken Coar]
976 *) In core_input_filter, check for an empty brigade after
977 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
978 client says it will post some data but we get FIN before any
979 data arrives. [Jeff Trawick]
981 *) Not being able to bind to the socket is a fatal error. We should
982 print an error to the console, and return a non-zero status code.
983 With these changes, all of the Unix MPMs do that correctly.
986 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
987 through to CGI scripts. PR 9163
988 [Brian Reid <breid@customlogic.com>,
989 Zvi Har'El <rl@math.technion.ac.il>]
991 *) binbuild.sh: Make sure that we use the expat from our source
992 tree so that there aren't any surprises on the target machine.
995 *) mod_cgid: Add retry logic for when the daemon can't fork fast
996 enough to keep up with new requests. Start using
997 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
998 when we can't talk to the daemon. [Jeff Trawick]
1000 *) apxs: LTFLAGS envvar can override default libtool options. Try
1001 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
1002 the covers. [Jeff Trawick]
1004 *) The Location: response header field, used for external
1005 redirect, *must* be an absoluteURI. The Redirect directive
1006 tested for that, but RedirectMatch didn't -- it would allow
1007 almost anything through. Now it will try to turn an abs_path
1008 into an absoluteURI, but it will correctly varf like Redirect
1009 if the final redirection target isn't an absoluteURI. [Ken Coar]
1011 Changes with Apache 2.0.31
1013 *) Create the scoreboard (in the parent) in a global pool context,
1014 so it survives graceful restarts. This fixes a SEGV during
1015 graceful restarts. [Aaron Bannert]
1017 *) Add a timeout option to the proxy code 'ProxyTimeout'
1020 *) FTP directory listings are now always retrieved in ASCII mode.
1021 The FTP proxy properly escapes URI's and HTML in the generated
1022 listing, and escapes the path components when talking to the FTP
1023 server. It is now possible to browse the root directory by using
1024 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
1025 Also, the last path component may contain wildcard characters
1026 '*' and '?', and if they do, a directory listing is created instead
1027 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
1030 *) Added single-listener unserialized accept support to the
1031 worker MPM [Brian Pane]
1033 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
1034 the incoming host header through to the proxied server
1035 [Geoff <g.russell@ieee.org>]
1037 *) New Directive Option for ProxyPass. It now can block a location
1038 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
1040 *) Don't let the default handler try to serve a raw directory. At
1041 best you get gibberish. Much worse things can happen depending
1042 on the OS. [Jeff Trawick]
1044 *) Change the pre_config hook to return a value. Modules can now emit
1045 an error message and then cause the server to quit gracefully during
1046 startup. This required a bump to the MMN. [Aaron Bannert]
1048 *) Fix some unix socket descriptor leaks in the handler side of
1049 mod_cgid (the part that runs in the server process). Whack a
1050 silly "close(-1)" in the handler too. [Jeff Trawick]
1052 *) Change the pre_mpm hook to return a value, so that scoreboard
1053 init errors percolate up to code that knows how to exit
1054 cleanly. This required a bump to the MMN. [Jeff Trawick]
1056 *) Add the socket back to the conn_rec and remove the create_connection
1057 hook. The create_connection hook had a design flaw that did not
1058 allow creating connections based on vhost info. [Bill Stoddard]
1060 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
1061 Resolves the common case of using negotation to resolve the request
1062 /script/foo for /script.cgi/foo. [William Rowe]
1064 *) Added new functions ap_add_(input|output)_filter_handle to
1065 allow modules to bypass the usual filter name lookup when
1066 adding hard-coded filters to a request [Brian Pane]
1068 *) caching should now work on subrequests (still very experimental)
1071 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
1073 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
1076 *) Refactor ap_rgetline so that it does not use an internal brigade.
1077 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
1079 *) Remove mod_auth_db. [Justin Erenkrantz]
1081 *) Do not install unnecessary pcre headers like config.h and internal.h.
1082 [Joe Orton <joe@manyfish.co.uk>]
1084 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
1085 (as it does for a normal request). quick_handled sub-requests now work
1086 in mod-include [Ian Holsman]
1088 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
1089 'CONTENT' one, as it needs to run AFTER all content headers
1091 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
1094 *) Split out blocking from the mode in the input filters.
1097 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
1099 *) Cause Win32 to capture all child-worker process errors in
1100 Apache to the main server error log, until the child can
1101 open its own error logs. [William Rowe]
1103 *) HPUX 11.*: Do not kill the child process when accept()
1104 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
1105 by [madhusudan_mathihalli@hp.com])
1108 *) Fix a problem in the parsing of the <Proxy foo> directive.
1111 *) rewrite of mod_ssl input filter for better performance and less
1112 memory usage [Doug MacEachern]
1114 *) allow quick_handler to be run on subrequests. [Ian Holsman]
1116 *) mod_dav now asks its provider to place content directly into the
1117 filter stack when handling a GET request. The mod_dav/provider
1118 API has changed, so providers need to be updated. [Greg Stein]
1120 *) Clear the output socket descriptor in unixd_accept() to make sure
1121 we don't supply a bogus socket to the caller if the accept fails.
1122 This caused problems with the worker MPM, which tried to process
1123 the returned socket if it was non-NULL. [Brian Pane]
1125 *) Move a check for an empty brigade to the start of core input filter
1126 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
1128 *) Add FileETag directive to allow configurable control of what
1129 data are used to form ETag values for file-based URIs. MMN
1130 bumped to 20020111 because of fields added to the end of
1131 the core_dir_config structure. [Ken Coar]
1133 *) Fix a segfault in mod_rewrite's logging code caused by passing the
1134 wrong config to ap_get_remote_host(). [Jeff Trawick]
1136 *) Allow mod_cgid to work from a binary distribution install by
1137 using 755 for the permissions on the log directory instead of
1140 *) Fixed a segfault that happened during graceful shutdown (or when
1141 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
1143 *) Split all Win32 modules [excluding the core components mod_core,
1144 mod_so, mod_win32 and the winnt mpm] into individual loadable
1145 modules, so the administrator may individually disable the former
1146 compiled-in modules by simply commenting out their LoadModule
1147 directives. [William Rowe]
1149 *) Saved Win32 module authors and porters many future headaches, by
1150 duplicating the appropriate .h files such as os.h into the include
1151 directory, including in the build tree. [William Rowe]
1153 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
1154 Use SSL functions/macros instead of directly dereferencing SSL
1155 structures wherever possible.
1156 Add type-casts for the cases where functions return a generic pointer.
1157 Add $SSL/include to configure search path.
1158 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1160 *) Moved several pointers out of the shared Scoreboard so it is
1161 more portable, and will present the vhost name across server
1162 generation restarts. [William Rowe]
1164 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
1167 Changes with Apache 2.0.30
1169 *) Fix the main bug for FreeBSD and threaded MPM's. There are
1170 still issues (see STATUS) but at least the server will now
1171 run without crashing the machine.
1172 [David Reid, Aaron Bannert, Justin Erenkrantz]
1174 *) Fix a typo in mod_deflate's m4 config section.
1175 [albert chin (china@thewrittenword.com)]
1177 *) Fix a couple of mod_proxy problems forwarding HTTP connections
1178 and handling CONNECT:
1179 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
1180 (2) Proxy failed to connect when the first IP address returned by
1181 the resolver was unreachable but a secondary IP address was.
1184 *) Fix the module identifer as shown in the docs for various core
1185 modules (e.g., the identifer for mod_log_config was previously
1186 listed as config_log_module). PR #9338
1187 [James Watson <ap2bug@sowega.org>]
1189 *) Fix LimitRequestBody directive by placing it in the HTTP
1190 filter. [Justin Erenkrantz]
1192 *) Fix mod_proxy seg fault when the proxied server returns
1193 an HTTP/0.9 response or a bogus status line.
1196 *) Prevent mod_proxy from truncating one character off the
1197 end of the status line returned from the proxied server.
1198 [Adam Sussman, Bill Stoddard]
1200 *) Eliminate loop in ap_proxy_string_read().
1201 [Adam Sussman, Bill Stoddard]
1203 *) Provide $0..$9 results from mod_include regex parsing.
1206 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
1208 *) Introduced the ForceLanguagePriority directive, to prevent
1209 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
1210 when using Multiviews. [William Rowe]
1212 *) Fix a problem which prevented mod_cgid and suexec from working
1213 together reliably [Greg Ames]
1215 *) Remove the call to exit() from within mod_auth_digest's post_config
1216 phase. [Aaron Bannert]
1218 *) Fix a problem in mod_auth_digest that could potentially cause
1219 problems with initialized static data on a system that uses DSOs.
1222 *) Fix a segfault in the worker MPM that could happen during
1223 child process exits. [Brian Pane, Aaron Bannert]
1225 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
1227 *) Fix matching of vhosts by ip address so we find IPv4
1228 vhost address when target address is v4-mapped form of
1229 that address. [Jeff Trawick]
1231 *) More performance tweaks to the BNDM string-search algorithm
1232 used to find "<!--#" tokens in mod_include [Brian Pane]
1234 *) Miscellaneous small performance fixes: optimized away various
1235 string copy operations and removed large temp buffers from
1236 the stack [Brian Pane]
1238 *) Fixed startup segfault that occurred when a VirtualHost
1239 directive had a port but no address [Brian Pane]
1241 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
1243 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
1244 if oslevel < WINNT. This should fix several problems reported
1245 Against 2.0.28 on Windows 98 [Bill Stoddard]
1247 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
1248 to fail. [Bill Stoddard]
1250 *) Change core code to allow an MPM to set hard thread/server
1251 limits at startup. prefork, worker, and perchild MPMs now have
1252 directives to set these limits. [Jeff Trawick]
1254 *) Win32: The async AcceptEx() event should be autoreset upon
1255 successful completion of a wait (WaitForSingleObject). This
1256 eliminates a number of spurious
1257 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
1260 *) Move any load library path environment variables out of
1261 apachectl and into a separate environment variable file which
1262 can be more easily tailored by the admin. The environment
1263 variable file as built by Apache may have additional system-
1264 specific settings. For example, on OS/390 we tailor the heap
1265 settings to allow lots of threads. [Jeff Trawick]
1267 *) Use the new APR pool code to reduce pool-related lock
1268 contention in the worker MPM. [Sander Striker]
1270 *) The POD no longer assumes the child is listening on 127.0.0.1
1271 and now pulls the first hostname in the list of listeners to
1272 perform the dummy connect on. This fixes a bug when the user
1273 had configured the Listen directive for an IP other than
1274 127.0.0.1. This would result in undead children and error
1275 messages such as "Connection refused: connect to listener".
1278 *) The worker MPM now respects the LockFile setting, needed to
1279 avoid locking problems with NFS. [Jeff Trawick]
1281 *) Fix segfault when worker MPM receives SIGHUP.
1282 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
1284 *) Fix bug that could potentially prevent the perchild MPM from
1285 working with more than one vhost/uid. [Aaron Bannert]
1287 *) Change make install and apxs -i processing of DSO modules to
1288 perform special handling on platforms where libtool doesn't install
1289 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
1290 which prevented standard LoadModule statements from working.
1293 *) Whenever mod_so is enabled (not just when there are DSOs for
1294 our modules), do whatever special magic is required for compiling/
1295 loading third-party modules. This allows third-party DSOs to
1296 be used on an AIX build when there were no built-in modules
1297 built as DSOs. (This should help on OS/390 and BeOS as well.)
1300 *) Allow apxs to be used to build DSOs on AIX without requiring the
1301 user to hard-code the list of import files. (This should help
1302 on OS/390 and BeOS as well.) [Jeff Trawick]
1304 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
1305 PR 8563, 8919 [William Rowe]
1307 *) Get binary builds working when libapr and libaprutil are built
1310 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
1311 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
1312 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
1314 *) Fix the handling of SSI directives in which the ">" of the
1315 terminating "-->" is the last byte in a file [Brian Pane]
1317 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
1318 message that we had back in apache-1.3 and still have scattered
1319 throughout our docs. [Aaron Bannert]
1321 *) Prevent the Win32 port from continuing after encountering an
1322 error in the command line args to apache. [William Rowe]
1324 *) On a error in the proxy, make it write a line to the error log
1327 *) Various mod_ssl performance improvements [Doug MacEachern]
1329 Changes with Apache 2.0.29
1331 *) Add buffering in core_output_filter to ensure that long
1332 lists of small buckets don't cause small packet writes.
1333 [Brian Pane, Ryan Bloom]
1335 *) Fix the installation target to make sure that the manual is
1336 installed in the correct location.
1337 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
1338 Gomez Henri <hgomez@slib.fr>]
1340 *) Fix the cmd command for mod_include. When we are processing
1341 a cmd command, we do not want to use the r->filename to set
1342 the command name. The command comes from the SSI tag. To do this,
1343 I added a variable to the function that builds the command line
1344 in mod_cgi. This allows the include_cmd function to specify
1345 the command line itself. [Ryan Bloom]
1347 *) Change open_logs hook to return a value, allowing you
1348 to flag a error while opening logs
1349 [Ian Holsman, Doug MacEachern]
1351 *) Change post_config hook to return a value, allowing you
1352 to flag a error post config
1353 [Ian Holsman, Jeff Trawick]
1355 *) Allow SUEXEC_BIN (the path to the suexec binary that is
1356 hard-coded into the server) to be specified to the configure
1357 script by the --with-suexec-bin parameter. [Aaron Bannert]
1359 *) Fix segv in worker MPM following accept on pipe-of-death
1362 *) Add mod_deflate to experimental.
1363 [Ian Holsman, Justin Erenkrantz]
1365 *) Bail out at configure time if an invalid MPM was specified.
1366 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1368 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
1369 configured [John Sterling <sterling@covalent.net>]
1371 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
1373 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
1375 *) Optimization for the BNDM string-search function in
1376 mod_include. [Brian Pane]
1378 *) Fixed the behavior of the XBitHack directive.
1379 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
1381 *) The threaded MPM for Unix has been removed. Use the worker
1382 MPM instead. [various]
1384 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
1385 in logging the error from a failed DNS lookup. [Jeff Trawick]
1387 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
1390 *) Get mod_cgid killed when a MPM exits due to a fatal error.
1393 *) Fix a file descriptor leak in mod_include. When we include a
1394 file, we use a sub-request, but we didn't destroy the sub-request
1395 immediately, instead we waited until the original request was
1396 done. This patch closes the sub-request as soon as the data is
1397 done being generated. [Brian Pane <bpane@pacbell.net>]
1399 *) Allow modules that add sockets to the ap_listeners list to
1400 define the function that should be used to accept on that
1401 socket. Each MPM can define their own function to use for
1402 the accept function with the MPM_ACCEPT_FUNC macro. This
1403 also abstracts out all of the Unix accept error handling
1404 logic, which has become out of synch across Unix MPMs.
1407 *) Fix a bug which would cause the response headers to be omitted
1408 when sending a negotiated ErrorDocument because the required
1409 filters were attached to the wrong request_rec.
1410 [John Sterling <sterling@covalent.net>]
1412 *) Remove commas from the end of the macros that define
1413 directives that are used by MPMs. Prior to this patch,
1414 you would use these macros without commas, which was unlike
1415 the macros for any other directives. Now, the caller provides
1416 the comma rather than the macro providing it. This makes
1417 the macros look more like the rest of the directives.
1418 [Ryan Bloom and Cliff Woolley]
1420 *) Add 'redirect-carefully' environment option to disable sending
1421 redirects under special circumstances. This is helpful for
1422 Microsoft's WebFolders when accessing a directory resource via
1423 DAV methods. [Justin Erenkrantz]
1425 *) Begin to abstract out the underlying transport layer.
1426 The first step is to remove the socket from the conn_rec,
1427 the server now lives in a context that is passed to the
1428 core's input and output filters. This forces us to be very
1429 careful when adding calls that use the socket directly,
1430 because the socket isn't available in most locations.
1433 *) Really reset the MaxClients value in worker and threaded
1434 when the configured value is not a multiple of the number
1435 of threads per child. We said we did previously but we
1436 forgot to. [Jeff Trawick]
1438 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
1440 *) If shared modules are requested and mod_so is not available,
1441 produce a fatal config-time error. [Justin Erenkrantz]
1443 *) Improve http2env's performance by cutting the work it has to
1444 do. [Brian Pane <bpane@pacbell.net>]
1446 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
1447 [Brian Pane <bpane@pacbell.net>]
1449 Changes with Apache 2.0.28
1451 *) Fix infinite loop in mod_cgid.c.
1452 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
1454 *) When no port is given in a "ServerName host" directive, the
1455 server_rec->port is now set to zero, not 80. That allows for
1456 run-time deduction of the correct server port (depending on
1457 SSL/plain, and depending also on the current setting of
1458 UseCanonicalName). This change makes redirections
1459 work, even with https:// connections. As in Apache-1.3, the
1460 connection's actual port number is never used, only the ServerName
1461 setting or the client's Host: setting. Documentation updated
1462 to reflect the change. [Martin Kraemer]
1464 *) Add a '%{note-name}e' argument to mod-headers, which works in
1465 the same way as mod_log_confg. [Ian Holsman]
1467 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
1468 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
1469 MPMs. [Cliff Woolley]
1471 *) Introduce htdbm, a user management utility for db/dbm authorization
1472 databases. [Mladen Turk <mturk@mappingsoft.com>]
1474 *) Optimize usage of strlen and strcat in ap_directory_walk.
1475 [Brian Pane <bpane@pacbell.net>]
1477 Changes with Apache 2.0.27
1479 *) Introduce an Apache mod_ssl initial configuration template
1480 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
1482 *) Fixed a memory leak in the getline parsing code that could
1483 be triggered by arbitrarily large header lines. Requests
1484 from the core input filter for single lines are now limited
1485 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
1487 *) Fix a truncation bug in how we print the port on the Via: header.
1488 The routine that prints the Via: header now takes a length for
1489 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
1491 *) Some syntax errors in mod_mime_magic's magic file can result
1492 in a 500 error, which previously was unlogged. Now we log the
1493 error. [Jeff Trawick]
1495 *) Add the support/checkgid helper app, which checks the run-time
1496 validity of group identifiers usable in the Group directive.
1499 *) Various --enable-so options have been fixed: --enable-so is
1500 treated as "static"; explicit --enable-so=shared issues an error;
1501 and explicit --enable-so fails with error on systems without
1502 APR_HAS_DSO. [Aaron Bannert]
1504 *) Fix a segfault in the core input filter when the client socket
1505 gets disconnected unexpectedly. [Cliff Woolley]
1507 *) Fix the reporting for child processes that die. This removes
1508 all of the non-portable W* macros from Apache.
1509 [Jeff Trawick and Ryan Bloom]
1511 *) Win32: Track and display "Parent Server Generation:" in
1512 mod_status output. The generation will be bumped at
1513 server graceful restart, when the child process exits
1514 by hitting MaxRequestsPerChild or if the child
1515 process exits abnormally. [Bill Stoddard]
1517 *) Win32: Fix problem where MaxRequestsPerChild directive was
1518 not being picked up in favor of the default. Enable
1519 the parent to start up a new child process immediately upon
1520 the old child starting shutdown.
1523 *) Fix some bungling of the remote port in rfc1413.c so that
1524 IdentityCheck retrieves the proper user id instead of failing
1525 and thus always returning "nobody."
1526 [Dick Streefland <Dick.Streefland@xs4all.nl>]
1528 *) Introduced thread saftey for mod_rewrite's internal cache.
1529 [Brian Pane <bpane@pacbell.net>]
1531 *) Simplified mod_env's directives to behave as most directives are
1532 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
1533 directive following that UnsetEnv within the same container.
1534 Also provides a runtime startup warning if a PassEnv configured
1535 environment value is undefined. [William Rowe]
1537 *) The worker MPM is now completely ported to APR's new lock API. It
1538 uses native APR types for thread mutexes, cross-process mutexes,
1539 and condition variables. [Aaron Bannert]
1541 *) Sync up documentation to remove all references to the now deprecated
1542 Port directive. [Justin Erenkrantz]
1544 *) Moved all ldap modules from the core to httpd-ldap sub-project
1547 *) Exit when we can't listen on any of the configured ports. This
1548 is the same behavior as 1.3, and it avoids having the MPMs to
1549 deal with bogus ap_listen_rec structures. [Jeff Trawick]
1551 *) Cleanup the proxy code that creates a request to the origin
1552 server. This change adds an optional hook, which allows modules
1553 to gain control while the request is created if the proxy module
1554 is loaded. The purpose of this hook is to allow modules to add
1555 input and/or output filters to the request to the origin. While
1556 I was at it, I made the core use this hook, so that proxy request
1557 creation uses some of the code from the core. This can still be
1558 greatly improved, but this is a good start. [Ryan Bloom]
1560 Changes with Apache 2.0.26
1562 *) Port the MaxClients changes from the worker MPM to the threaded
1565 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
1566 with the new input filtering system. [Justin Erenkrantz]
1568 *) Introduce the MultiviewsMatch directive, to allow the operator
1569 to be flexible in recognizing Handlers and Filters filename
1570 extensions as part of the Multiviews matching logic, strict with
1571 MultiviewsMatch NegotiatedOnly to accept only filename extentions
1572 that designate negotiated parameters, (content type, charset, etc.)
1573 or MultiviewsAll for the 1.3 behavior of matching any files, even
1574 if they have unregistered extensions. [William Rowe]
1576 *) Fixed the configure script to add a LoadModule directive to
1577 the default httpd.conf for any module that was compiled
1578 as a DSO. [Aaron Bannert <aaron@clove.org>]
1580 *) rewrite mod_ssl input filtering to work with the new input filtering
1581 system. [Justin Erenkrantz]
1583 *) prefork: Don't segfault when we are able to listen on some but
1584 not all of the configured ports. [Jeff Trawick]
1586 *) Build mod_so even if no core modules are built shared.
1587 [Aaron Bannert <aaron@clove.org>]
1589 *) Introduce ap_directory_walk rewrite (with further optimizations
1590 required) to adapt to the ap_process_request_internal() changes.
1591 Optimized so subrequests and redirects now reuse previous section
1592 merges, until we mismatch with the original directory_walk, and
1593 precomputed r->finfo results will cause directory_walk to skip
1594 the most expensive phases of the function. [William Rowe]
1596 *) Allow ApacheMonitor to connect to and control Apache on other
1597 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
1599 *) Remove the Port directive. In it's place, the Listen directive
1600 is now a required directive, which tells Apache what port to
1601 listen on. The ServerName directive has also been extended
1602 to accept an optional port. If the port is specified to the
1603 ServerName, the server will report that port whenever it
1604 reports the port that it is listening on. This change was
1605 made to ease configuration errors that stem from having a Port
1606 directive, and a Listen directive. In that situation, the server
1607 would only listen to the port specified by the Listen command,
1608 which caused a lot of confusion to users. [Ryan Bloom]
1610 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
1611 build, as loadable modules. [William Rowe]
1613 *) Fix --enable-mods-shared processing. If most is specified,
1614 then all modules that can be compiled as shared modules are.
1615 [Aaron Bannert <aaron@clove.org>]
1617 *) Update the mime.types file to map video/vnd.mpegurl to mxu
1618 and add commonly used audio/x-mpegurl for m3u extensions.
1619 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
1621 *) Eliminate the depreciated r->content_language, in favor of the array
1622 r->content_languages introduced many years ago. Module authors must
1623 substantially overhaul their modules, so this needs to be upgraded
1624 if the module still relied on backwards-brokeness. [William Rowe]
1626 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
1629 *) Rewrite the input filtering mechanisms to consolidate and reorganize
1630 code. In short, core_input_filter does something now and
1631 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
1633 *) Update the Win32 build to re-absorb mod_proxy and family.
1636 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
1637 current SDK.) [William Rowe]
1639 *) Some style changes to the code that does ProxyErrorOverride. Fixed
1640 config merge behaviour. [Graham Leggett]
1642 *) Allow support programs to be compiled against a static version
1643 of libapr. This allows the smaller support programs to be
1644 relocated. [Aaron Bannert <aaron@clove.org>]
1646 *) Update the mime.types file to the registered media types as
1647 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
1649 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
1650 number of clients that can connect at the same time, instead of
1651 specifying the maximum number of child processes.
1652 [Aaron Bannert <aaron@clove.org>]
1654 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
1655 be consistent with 1.3. [Justin Erenkrantz]
1657 *) Cache apr_explode_localtime() value for 15 seconds.
1658 [Brian Pane <bpane@pacbell.net>]
1660 *) Fix mod_include to not return ETag or Last-Modified headers.
1661 [Ian Holsman <ianh@cnet.com>]
1663 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
1665 *) Eliminate the wasteful run-time conversion of method names from strings
1666 to numbers in places where the methods are known at compile time.
1667 [Brian Pane <bpane@pacbell.net>]
1669 *) Turn the worker MPM's queue into a LIFO. This may
1670 improve cache-hit performance under some conditions.
1671 [Aaron Bannert <aaron@clove.org>]
1673 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
1674 support it. [Justin Erenkrantz]
1676 *) Cleanup the worker MPM. We no longer re-use transaction
1677 pools. This incurs less overhead than shuffling the pools
1678 around so that they can be re-used. Remove one of the
1679 queue's condition variables. We just redefined the API to
1680 state that you can't try to add more stuff than you allocated
1681 segments for. [Aaron Bannert <aaron@clove.org>]
1683 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
1685 *) Fixed persistent connections when a request contains a body.
1688 *) mod_dav uses a new API to speak to the backend provider for dead
1689 property management. [Greg Stein]
1691 *) Remove the Win32 script-processing exception from mod_cgi, and
1692 roll build_command_line/build_argv_list into a unified, overrideable
1693 ap_cgi_build_command optional function. [William Rowe]
1695 *) Rewrite find_start_sequence to use a better search algorithm
1696 to find the start tag. [Justin Erenkrantz]
1698 *) Fix a seg fault in mod_include. When we are generating an
1699 internal redirect, we must set r->uri to "", not a bogus
1700 string, and not NULL. [Ryan Bloom]
1702 *) Optimized location_walk, so subrequests, redirects and second passes
1703 now reuse previous section merges on a <Location > by <Location >
1704 basis, until we mismatch with the original location_walk.
1707 *) Back out the 1.45 change to util_script.c. This change made
1708 us set the environment variable REQUEST_URI to the redirected
1709 URI, instead of the originally requested URI.
1710 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1712 *) Make mod_include do lazy evaluation of potentially expensive to
1713 compute variables. [Brian Pane <bpane@pacbell.net>]
1715 *) Fix logging of bytes sent for HEAD requests. %b and %B should
1716 log either - or 0, before this patch, they were both logging
1717 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1719 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
1720 than per character. [Brian Pane <bpane@pacbell.net>]
1722 *) Normalize the primary request, redirects and sub-requests to
1723 run the same ap_process_request_internal for consistency in
1724 robustness, behavior and security. [William Rowe]
1726 *) Fix a segfault with mod_include when r->path_info is not set
1727 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
1729 *) Add -X functionality back. This indicates to all MPMs and any other
1730 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
1732 *) Some initial support for the cygwin platform [prefork only].
1733 This is not to be confused with support for the WinNT/Win32
1734 platform, which is the recommended configuration for native
1735 Win32 users. The cygwin platform support is recommended for
1736 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
1738 *) Changed syntax of Set{Input|Output}Filter. The list of filters
1739 must be semicolon delimited (if more than one filter is given.)
1740 The Set{Input|Output}Filter directive now overrides a parent
1741 container's directive (e.g. SetInputFilter in <Directory /web/foo>
1742 will override any SetInputFilter directive in <Directory /web>.)
1743 This new syntax is more consistent with Add{Input|Output}Filter
1744 directives defined in mod_mime. Also cures a bug in prior releases
1745 where the Set{Input|Output}Filter directive would corrupt the
1746 global configuration if the multiple directives were nested.
1749 *) Cured what's ailed mime for quite some time. If an AddSomething
1750 was given in the configuration (Language, Charset, Handler or
1751 Encoding) Apache would set the content type as given by AddType,
1752 but refused to check the mime.types file if AddType wasn't given
1753 for that specific extension. Setting the AddHandler for .html
1754 without setting the AddType text/html html would cause Apache to
1755 use the default content type. [William Rowe]
1757 *) Added some bulletproofing to memory allocation in the LDAP cache
1758 code. [Graham Leggett]
1760 Changes with Apache 2.0.25
1762 *) Move the installed /manual directory out of the /htdocs/ tree, so
1763 that it can be kept more independently from the remaining document
1764 root. The "Alias /manual ..." already allowed for easy projection
1765 into existing private document trees. [Martin Kraemer]
1767 *) Add specified user attributes to the environment when using
1768 mod_auth_ldap. This allows you to use mod_include to embed specified
1769 user attributes in a page like so:
1770 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
1773 *) Fix a performance problem with the worker MPM. We now create
1774 transaction pools once, and re-use them for each connection.
1775 [Aaron Bannert <aaron@clove.org>]
1777 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
1778 of a 'handler' or 'filter', so that any filename extension that does
1779 not contribute to the negotiated metadata can't be served without
1780 an explicit request. E.g., if the .Z extension is associated with
1781 an unzip filter, the user request somefile.Z.html, mod_negotiation
1782 won't serve it. It can serve somefile.Z.html when somefile.Z is
1783 requested, since the .Z extension is explictly requested, if the
1784 .html extension is associated with ContentType text/html.
1787 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
1788 and corresponding AddOutputFilter syntax, to insert one or more
1789 filters by mod_mime filename extension processing.
1792 *) Fix a growing connection pool in core_output_filter() for
1793 keepalive requests. [Jeff Trawick]
1795 *) Moved split_and_pass_pretag_buckets back to being a
1796 macro at Ryans's request. Removed the return from it
1797 by setting and returning a return code instead. Updated
1798 the code to check the return code from the macro and
1799 do the right thing. [Paul J. Reder]
1801 *) Fix a segfault when a numeric value was received for Host:.
1804 *) Add a function ap_remove_input_filter. This is to match
1805 up with ap_remove_output_filter. [Ryan Bloom]
1807 *) Clean up location_walk, so that this step performs a minimum
1808 amount of redundant effort (it must be run twice, but it will no
1809 longer reparse all <Location > blocks when the request uri
1810 hadn't changed.) [William Rowe]
1812 *) Eliminate proxy: (and all other 'special') processing from the
1813 ap_directory_walk() phase. Modules that want to use special
1814 walk logic should refer to the mod_proxy map_to_location example,
1815 with it's proxy_walk and proxysection implementation. This makes
1816 either directory_walk flavor much more legible, since that phase
1817 only runs against real <Directory > blocks.
1820 *) Fix a security problem in mod_include which would allow
1821 an SSI document to be passed to the client unparsed.
1822 [Cliff Woolley, Brian Pane]
1824 *) Introduce the map_to_storage hook, which allows modules to bypass
1825 the directory_walk and file_walk for non-file requests. TRACE
1826 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
1827 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
1830 *) Add the ability for mod_include to add the INCLUDES filter
1831 if the file is configured for the server-parsed handler.
1832 This makes the configuration for .shtml files much easier
1833 to understand, and allows mod_include to honor Apache 1.3
1834 config files. Based on Doug MacEachern's patch to PHP
1835 to do the same thing. [Ryan Bloom]
1837 *) force OpenSSL to ignore process local-caching and to always
1838 get/set/delete sessions using mod_ssl's callbacks
1839 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1840 Geoff Thorpe <geoff@geoffthorpe.net>]
1842 *) Make the worker MPM shutdown and restart cleanly. This also
1843 cleans up some race conditions, and gets the worker using
1844 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
1846 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
1848 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1850 *) Fix for mod_include. Ryan's patch to check error
1851 codes put a return in the wrong place. Also, the
1852 include handler return code wasn't being checked.
1853 I don't like macros with returns, so I converted
1854 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
1855 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1857 *) fix segv in mod_mime if no AddTypes are configured
1858 [John Sterling <sterling@covalent.net>]
1860 *) Enable ssl client authentication at SSL_accept time
1861 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1863 *) Fix a segfault in mod_include when the original request has no
1864 associated filename (e.g., we're filtering the error document for
1865 a bad URI). [Jeff Trawick]
1867 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
1869 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
1870 of httpd is started and shuts down due to socket conflict. Moving the
1871 call to ap_log_pid solves the problem.
1873 *) Changed the late-1.3 log_config substitution %c to %X, to log the
1874 status of the closed connection, as it conflicts with the far more
1875 common, historical ssl logging directive %...{var}c. [William Rowe]
1877 *) Added the common error/ tree to the build/install targets
1878 (similar to the common icons/ tree) for the multi-language error
1879 messages that Lars committed earlier. [William Rowe]
1881 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
1883 *) Added a default commented-out mod_ldap and mod_auth_ldap
1884 configuration to httpd-std.conf and httpd-win.conf
1887 *) Added documentation for mod_ldap and mod_auth_ldap.
1890 *) Enabled negative caching on attribute comparisons in the LDAP cache.
1891 Fixed a problem where the default cache TTL was set in milliseconds
1892 not microseconds causing the cache to time out almost immediately.
1895 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
1896 module code to follow APR. [Graham Leggett]
1898 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
1899 cleaned up when the connection pool pool is cleaned up.
1902 *) Fix a minor issue with Jeff Trawick's mod_include
1903 patch. Without this patch, the code will just allocate
1904 more bytes in get_combined_directive than are needed.
1907 *) Added the LDAP authentication module mod_auth_ldap.
1908 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1910 *) Added the LDAP cache and connection pooling module mod_ldap.
1911 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1913 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
1914 by allowing a module to disable itself if its prerequisites are not
1915 met. [Justin Erenkrantz]
1917 Changes with Apache 2.0.24
1919 *) Fix a couple of issues in mod_include when the tag appeared at
1920 offsets near 8192 in the file being parsed. [Jeff Trawick]
1922 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
1923 reached. [Jeff Trawick]
1925 *) Numerous improvements to the Win32 build system. Introduced command line
1926 builds without requiring .mak files for MSVC 6.0 and later versions.
1927 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
1930 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
1931 reporting of uninstalled services and other error conditions, and changed the
1932 default service name to Apache2. [William Rowe]
1934 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
1935 compatibility with existing Apache 1.3 Win32 Apache management utilites.
1936 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
1938 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
1939 [William Rowe, Greg Ames]
1941 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
1942 and RemoveCharset directives. [William Rowe]
1944 *) The Unix MPMs other than perchild now allow child server
1945 processes to use the accept mutex when starting as root and
1946 using SysV sems for the accept mutex. Previously, this
1947 combination would lead to fatal errors in the child server
1948 processes. perchild can't use SysV sems because of security
1949 issues. [Jeff Trawick, Greg Ames]
1951 *) Added Win32 revision stamp resources to all http binaries
1952 (including modules/ and support/ tools.) PR7322 [William Rowe]
1954 *) Fix ap_rvprintf to support more than 4K of data at one time.
1955 [Cody Sherr <csherr@covalent.net>]
1957 *) We have always used the obsolete/deprecated Netscape syntax
1958 for our tracking cookies; now the CookieStyle directive
1959 allows the Webmaster to choose the Netscape, RFC2109, or
1960 RFC2965 format. The new CookieDomain directive allows the
1961 setting of the cookie's Domain= attribute, too. PR #s 5006,
1962 5023, 5920, 6140 [Ken Coar]
1964 *) Tweak server/Makefile so that the rules for generating exports.c
1965 are compatible with make utilities which don't expand wildcards
1966 in a dependency list (e.g., OS/390 make, certain levels of GNU
1967 make). [Jeff Trawick]
1969 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
1971 *) Begin to sanitize the MPM configuration directives. Now, all
1972 MPMs use the same functions for all common MPM directives. This
1973 should make it easier to catch all bugs in these directives once.
1974 [Cody Sherr <csherr@covalent.net>]
1976 *) Close a major resource leak. Every time we had issued a
1977 graceful restart, we leaked a socket descriptor.
1980 *) Fix a problem with the new method code. We need to cast
1981 the 1 to an apr_int64_t or it will be treated as a 32-bit
1982 integer, and it will wrap after being shifted 32 times.
1983 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
1985 *) Fix a bug in mod_expires. Previous to this patch, if you
1986 told mod_expires to add 604800 seconds to the last-modified
1987 time, it actually added 604800 usec's to the last-modified time,
1988 so that when looking at the response it looked like nothing
1989 had been done. The root of the problem was that we always compute
1990 time in usec's, but we ask users to input sec's. This means we
1991 need to convert to usec's before using those values.
1994 *) The worker MPM now handles shutdown and restart requests. It
1995 definitely isn't perfect, but we do stop the servers correctly.
1996 The biggest problem right now is that SIGHUP causes the server to
1997 just die. [Ryan Bloom]
1999 Changes with Apache 2.0.23
2001 *) Use the prefork MPM by default on Unix. [various]
2003 *) Added a systray icon monitor application for Win32.
2004 [Mladen Turk <mturk@mappingsoft.com>]
2006 *) mod_rewrite: Fix the line ending on some non-Unix systems for
2007 messages written to the rewrite log.
2008 [Richard Labennett <rlabenn@us.ibm.com>]
2010 *) All mod_autoindex query parsing is now quietly quashed with the
2011 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
2012 still drops the column sort <a href>'s for the column headers, but
2013 IgnoreClient is required to ignore these Query options entirely.
2016 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
2017 to allow the client to select plain, FancyIndexing or HTMLTable
2018 formatting, V=[0|1] to inhibit or enable version sorting, and
2019 P=pattern to return only specific files. The old Query Arguments
2020 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
2021 as before), and O=A|D for ordering ascending or descending.
2024 *) Fixed an error in mod_include's directive parsing routines which
2025 caused #if, #elif, and #else expressions containing backslashes
2026 to be improperly evaluated. [Cliff Woolley]
2028 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
2029 drop the icon column, SuppressRules to drop the <hr> elements,
2030 and HTMLTable to create rudimentary HTML table listings (implies
2031 FancyIndexing). [William Rowe]
2033 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
2034 from Apache 1.3.15. This is needed for two reasons, first, given
2035 multiple machines within a server farm, ETags and Last-Modified
2036 stamps won't correspond from machine to machine, and second, many
2037 Unixes don't capture changes to the date or time stamp of existing
2038 files, since these don't modify the dirent itself. [William Rowe]
2040 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
2041 and DirectoryWidth options from Apache 1.3.10.
2042 [William Rowe, Ken Coar]
2044 *) Eliminated FancyIndexing directive, deprecated early in Apache
2045 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
2047 *) mod_autoindex now excludes any file names that would result in
2048 an error, other than a success or redirect. Also optimized
2049 the parent directory, always included except in the URI '/'.
2052 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
2053 negotiated index pages, and prevent the server from defaulting
2054 to an autoindex of the directory. mod_negotiation will now die
2055 with a 500 Internal Error if it could match some filenames
2056 (e.g. for mod_dir) but none can be served. mod_negotation now
2057 refuses to serve any file with an extention that mod_mime doesn't
2058 recognize, and wasn't part of the request. [William Rowe]
2060 *) Eliminate mod_cgi's handling of .exe files without the .exe file
2061 extension. This is already handled by multiviews, if the admin
2062 wishes to AddHandler .exe or define a content type handler and
2063 associate .exe files with that content type. Multiviews must be
2064 enabled to allow these to be served. [William Rowe]
2066 *) Speed up the server's response to a spike in incoming workload
2067 or restarts by assigning empty scoreboard slots to new processes
2068 when they are available. [Greg Ames]
2070 *) Add a handler to mod_includes.c. This handler is designed to
2071 implement the XbitHack directive. This can't be done with a
2072 fixup, because we need to check the content-type, which is
2073 only available in the handler phase. [Ryan Bloom]
2075 *) Make the includes filter check return codes from filters lower in
2076 the filter chain. If a lower level filter returns an error, then
2077 the request needs to stop immediately. This allows mod_include to
2078 stop parsing data once a lower filter recognizes an error.
2081 *) Add the ability to extend the methods that Apache understands
2082 and have those methods <limit>able in the httpd.conf. It uses
2083 the same bit mask/shifted offset as the original HTTP methods
2084 such as M_GET or M_POST, but expands the total bits from an int to
2085 an ap_int64_t to handle more bits for new request methods than
2086 an int provides. [Cody Sherr <csherr@covalent.net>]
2088 *) Fix broken mod_mime behavior in merging its arguments. Possible
2089 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
2091 *) Solve many mod_ssl porting issues (too many to detail) with
2092 help from the whole team, but most notably [Ralf S. Engelschall,
2093 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
2094 Doug MacEachern, William Rowe, Cliff Woolley]
2096 *) More stall fixes for the threaded & worker mpm's.
2097 Make mod_status output more accurate. Don't
2098 count workers in processes which aren't actively
2099 serving requests. [Greg Ames]
2101 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
2103 *) Add a single listener/multiple worker MPM. This MPM is
2104 definately not fully correct, but it allows us to solve many
2105 of the problems that exist in the threaded MPM. This is a
2106 modified version of the threaded MPM. [Ryan Bloom]
2108 *) Improve content generation throughout Apache, providing closer
2109 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
2110 Transitional specifications. [William Rowe]
2112 Changes with Apache 2.0.22
2114 *) Fix a problem where the threaded MPM stalls after restarts or
2115 segfaults. Also prevent multiple active processes from using
2116 the same scoreboard slot. [Greg Ames]
2118 *) Apache/Win32 now fills in the service description with Apache's
2119 server version string, including loaded and advertised modules.
2122 *) Improved support for the Win32 build, to recover gracefully from
2123 missing apr or apr-util directories or the awk interpreter,
2124 create the proper cgi-bin examples, including a test-cgi.bat, and
2125 fix the perl shebang line for printenv.pl, when installing from
2126 the build environment. [William Rowe]
2128 *) Fix a segfault in threaded.c caused by passing uninitialized
2129 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
2131 *) Use new APR number conversion functions to reduce CPU consumption
2132 when setting the content length, and in mod_log_config.
2135 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
2136 where HEAD response headers were being repeated twice for
2137 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
2138 problem in the http_header filter was exposed by the recent rewrite
2139 of the content_length filter. [Taketo Kabe, Bill Stoddard]
2141 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
2142 restarts. A garbage pointer to a vhost's server_rec from the
2143 previous generation was being left around under certain
2144 conditions. [Greg Ames]
2146 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
2147 used to appear as '(none', without the closing paren.
2148 [Günter Knauf <eflash@gmx.net>]
2150 *) Improve the exports generating awk script. In the past, we had
2151 work around problems in the awk script by avoiding some #if and
2152 #ifdefs. This has bitten us many times in generating the exports.c
2153 file. This improvement allows corrects the header file parsing.
2154 [Sander Striker <striker@apache.org>]
2156 Changes with Apache 2.0.21
2158 *) Resolve the Win32 htpasswd bug, where a file that existed would be
2159 overwritten, regardless of the -c flag.
2160 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
2162 *) Introduce connection sub-pools into ab. Truncating the lifetime
2163 of these allocations means that ab no longer perpetually grows
2164 its working set, running out of memory on large request attempts.
2167 *) Make scoreboard creation a hook. This allows management
2168 modules to have access to the scoreboard at the time that it is
2169 created, and at every restart request.
2170 [Cody Sherr <csherr@covalent.net>]
2172 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
2173 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
2174 daemon index actually used in the scoreboard. I also
2175 updated the pertinent calls. [Paul J. Reder]
2177 *) Win32: Prevent listening sockets from being inherited by
2178 the Apache child process, CGI scripts, rotatelog process
2179 etc. If the Apache child process segfaults, any processes
2180 that the child started are not reaped. Prior to this fix,
2181 these processes inherited the listening sockets which sometimes
2182 prevented the restarted Apache child process from accepting
2183 connections (ie, the server would hang).
2186 *) Provide vhost and request strings when ExtendedStatus is on.
2189 *) Fix some issues with the pod and prefork: check the pod *after*
2190 processing a connection so that a server processing a time-
2191 consuming request bails out as soon as practical; when the
2192 parent process wakes up a server process via connect(), use an
2193 APR timeout on the connect() so that we don't hang for a long
2194 time if there aren't server processes around to do accept().
2195 [Jeff Trawick, Greg Ames]
2197 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
2198 spends a lot of time in apr_table_get calls. Using the default
2199 httpd.conf, the tables for languages and charsets are somewhat
2200 large, so the time spent scanning them on each request is
2201 significant. Replacing the tables with hash tables provides
2202 a nice speedup. [Brian Pane <bpane@pacbell.net>]
2204 *) Add two functions to allow modules to access random parts of the
2205 scoreboard. This allows modules compiled for one MPM to access the
2206 scoreboard, even if it the server was compiled for another MPM.
2207 [Harrie Hazewinkel <harrie@covalent.net>]
2209 Changes with Apache 2.0.20
2211 *) Fix problem in content-length filter where the filter would
2212 buffer all the output from a CGI before sending any bytes
2213 down the filter stack to the network. This problem would cause
2214 significant memory consumption if the CGIs generated
2215 lots of bytes. [Bill Stoddard]
2217 *) Get non-blocking CGI pipe reads working with the bucket brigades.
2220 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
2223 *) Fix a bug in the threaded MPM that would cause it to kill off all
2224 workers immediately after starting if the number of workers started
2225 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
2227 Changes with Apache 2.0.19
2229 *) Fix problem with threaded MPM. The problem was that if each child
2230 process was busy serving a single long-lived request and the server
2231 was sent a graceful restart signal, the server would stop serving
2232 requests. This would happen because each child process would wait to
2233 die until the last thread was done, and the parent wouldn't spawn any
2234 new children until a process died. Now, the parent looks at the fact
2235 that the children are dying gracefully, and starts new children.
2236 Those new children only start enough threads to compliment the number
2237 of threads in the other child process that shares the same spot in
2238 the scoreboard. In this way, we make sure to never go over
2239 MaxClients. [Ryan Bloom]
2241 *) modified mod_negotiation and mod_autoindex to speed up by almost a
2242 factor of two on apr_dir_read()-enhanced platforms, such as Win32
2243 and OS2, by calling ap_sub_request_lookup_dirent() with the results
2244 already provided by apr_dir_read(). [William Rowe]
2246 *) mod_file_cache is now more robust to filtering and serves requests
2247 slightly more efficiently. [Cliff Woolley]
2249 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
2250 Module was calling ap_rwrite() followed by ap_rflush() but the
2251 served content was not being displayed in the browser. Inspection
2252 of the output stream revealed that the first data chunk was
2253 missing the trailing CRLF required by the RFC. [Bill Stoddard]
2255 *) apxs no longer generates ap_send_http_header() in the example handler
2257 *) Fix an ab problem which could cause a divide-by-zero exception
2258 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
2259 [Ian Holsman <ianh@cnet.com>]
2261 *) Solve case-insensitive platforms' confusion about negotiated
2262 filenames, allowing files of differnt case to match in choosing
2263 the document to serve. [William Rowe]
2265 *) Fix brokenness when ThreadsPerChild is higher than the built-in
2266 limit. We left ap_threads_per_child at the higher value which
2267 led to segfaults when doing certain scoreboard operations.
2270 *) Fix seg faults and/or missing output from mod_include. The
2271 default_handler was using the subrequest pool for files and
2272 MMAPs, even though the associated APR structures typically
2273 live longer than the subrequest. [Greg Ames]
2275 *) Extend mod_setenvif to support specifying regular expressions
2276 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
2277 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
2278 will cause HAVE_TS to be set if any of the request headers begins
2279 with "TS" and has a value that begins with any character in the
2280 set [a-z]. [Bill Stoddard]
2282 *) httpd children now re-bind themselves to a random CPU on
2283 multiprocessor systems on AIX via bindprocessor() in 2.0.
2284 [Victor J. Orlikowski]
2286 *) Fix htdigest. It would go into a loop in getline when adding
2287 a second user. [Bill Stoddard]
2289 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
2291 *) Automatically generate httpd.exp for AIX.
2292 DSOs now work again on AIX in 2.0
2293 [Victor J. Orlikowski]
2295 *) Add a new request hook, error_log. This phase allows modules
2296 to act on the error log string _after_ it has been written
2297 to the error log. The goal for this hook is to allow monitoring
2298 modules to send the error string to the monitoring agent.
2301 *) Modify mod_echo to make it use filters for input and output.
2302 [Ryan Morgan <rmorgan@covalent.net>]
2304 *) Extend mod_headers to support conditional driven Header
2305 add, append and set. Use SetEnvIf to set an envar and conditionally
2306 add/append/set headers based on this envar thusly:
2308 SetEnvIf TSMyHeader value HAVE_TSMyHeader
2309 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
2311 If the request contains header "TSMyHeader: value" then header
2312 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
2315 *) Extend mod_headers to support using format specifiers on Header
2316 add, append and set header values. Two format specifiers are supported:
2318 %t - reports, in UTC microseconds since the epoch, when the
2319 request was received.
2321 %D - reports the time, in microseconds, between when the request was
2322 received and the response sent.
2325 Header add MyHeader "This request served in %D microseconds. %t"
2327 results in a header being added to the response that looks like this:
2329 MyHeader: This request served in D=5438 microseconds. t=991424704447256
2333 *) Fix reset_filter(). We need to be careful how we remove filters.
2334 If we set r->output_filters to NULL, we also have to reset the
2335 connection's filters. [John Sterling]
2337 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
2339 *) Add a check to ap_die() to make sure the filter stack is sane and
2340 contains the correct basic filters when an error occurs. This fixes
2341 a problem where headers are not being sent on error. [John Sterling]
2343 *) New Header directive 'echo' option. "Header echo regex" will
2344 cause any headers received on the request that match regex to be
2345 echoed to (included in) the response headers.
2348 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
2349 This prevented the inclusion of apr_compat.h. PR #7773
2350 [Oleg Broytmann <phd@phd.pp.ru>]
2352 *) Moved util_uri to the apr-util library. This required a bunch of
2353 apr_name changes for the uri utility functions. [Justin Erenkrantz]
2355 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
2356 insert_filter phase so that other filters are not bypassed by default.
2359 *) Reimplement mod_headers as an output filter. mod_headers can now
2360 add custom headers to inbound requests using the RequestHeader directive
2361 and to responses using the same old Header directive. [Graham Leggett]
2363 Changes with Apache 2.0.18
2365 *) Fix command-line processing so that if a bad argument is specified
2366 Apache will exit. [Jeff Trawick]
2368 *) Change the make targets and rules to be consistent in all of the
2369 Apache-owned source trees. [Roy Fielding]
2371 *) Fix processing of the TRACE method. Previously we passed bogus
2372 parms to form_header_field() and it overlaid some vhost structures,
2373 resulting in a segfault in check_hostalias().
2374 [Greg Ames, Jeff Trawick]
2376 *) Win32: Add support for reliable piped logs. If the logging process
2377 goes down, Apache will automatically restart it. This function has
2378 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
2381 *) Do not start piped log processes during the config file
2382 preflight. This change also circumvents a problem on
2383 Windows where the rotatelog processes created during preflight
2384 was not getting cleaned up properly.
2387 *) add "Request Phase Participation" info to mod_info
2390 *) Make first phase changes to the scoreboard data structures in
2391 preparation for the rewriting of the scoreboard per my posted
2392 design notes. [Paul J. Reder]
2394 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
2395 and apr-util, allow it to be overridden by the configure command-line
2396 (default="--silent") and introduce LT_LDFLAGS to replace what we were
2397 formerly abusing as LTFLAGS. [Roy Fielding]
2399 *) Clean up the reporting of incorrect closing container tags.
2400 [Barrie Slaymaker <barries@slaysys.com>]
2402 *) Simplify the configure process by moving all libtool stuff to APR
2403 and moving hints.m4 inline. [Roy Fielding]
2405 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
2406 of functions used by mod_proxy for export in the DLL
2407 [Ian Holsman <IanH@cnet.com>]
2409 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
2410 request body from its stdin but no reqest body is being written to
2411 the cgi. [Jeff Trawick]
2413 *) mod_log_config: %c connection status incorrectly logged
2414 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
2417 *) Get mod_cern_meta working under Windows
2420 *) Create Files, and thus MMAPs, out of the request pool, not the
2421 connection pool. This solves a small resource leak that had us
2422 not closing files until a connection was closed. In order to do
2423 this, at the end of the core_output_filter, we loop through the
2424 brigade and convert any data we have into a single HEAP bucket
2425 that we know will survive clearing the request_rec.
2426 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
2429 *) Completely revamp configure so that it preserves the standard make
2430 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
2431 the configure additions to EXTRA_* variables. Also, allow the user
2432 to specify NOTEST_* values for all of the above, which eliminates the
2433 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
2434 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
2435 avoid pointless duplications. Fix the order in which flags are given
2436 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
2437 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
2438 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
2439 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
2441 *) Get mod_tls to compile/work better on Windows. PR #7612
2442 [Bernhard Schrenk <b.schrenk@improx.com>]
2444 *) Fix shutdown/restart hangs in the threaded MPM.
2445 [Jeff Trawick, Greg Ames, Ryan Bloom]
2447 *) Removed the keptalive boolean from conn_rec because it is now only
2448 used by a single routine and can be replaced by a local variable.
2449 [Greg Stein, Ryan Bloom, Roy Fielding]
2451 *) Patch prefork to put enough of the signal processing back in so that
2452 signals are all handled properly now. The previous patch fixed the
2453 deadlock race condition, but broke the user directed signal handling.
2454 This fixes it to work the way it did before my previous prefork patch
2455 (primarily, SIGTERM is now working).
2457 *) Change how input filters decide how much data is returned to the
2458 higher filter. We used to use a field in the conn_rec, with this
2459 change, we use an argument to ap_get_brigade to determine how much
2460 data is retrieved. [Ryan Bloom]
2462 *) Fix seg fault at start-up introduced by Ryan's change to enable
2463 modules to specify their own logging tags. mod_log_config
2464 registers an optional function, ap_register_log_handler().
2465 ap_register_log_handler() was being called by http_core before
2466 the directive hash table was created. This patch creates the
2467 directive hash table before ap_register_log_handler() is
2468 registered as an optional function.
2469 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2471 *) Add ap_set_int_slot() function
2472 [John K. Sterling <sterling@covalent.net>]
2474 *) Under certain circumstances, Apache did not supply the
2475 right response headers when requiring authentication.
2476 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
2477 (This is a port of the change that went into Apache 1.3.19.)
2479 *) Allow modules to specify their own logging tags. This basically
2480 allows a module to tell mod_log_config that when %x is encountered
2481 a specific function should be called. Currently, x can be any single
2482 character. It may be more useful to make this a string at some point.
2485 Changes with Apache 2.0.17
2487 *) If a higher-level filter handles the the byterange aspects of a
2488 request, then the byterange filter should not try to redo the
2489 work. The most common case of this happening, is a byterange
2490 request going through the proxy, and the origin server handles
2491 the byterange request. The proxy should ignore it.
2492 [Graham Leggett <minfrin@sharp.fm>]
2494 *) Changed the threaded mpm to have child_main join to each of the
2495 worker threads to make sure the kids are all gone before child_main
2496 exits after a signal (cleanup from perform_idle_server_maintenance).
2497 This is an extension of Ryans recent commit to make the child_main
2500 *) Add more options to the ap_mpm_query function. This also allows MPMs to
2501 report if their threads are dynamic or static. Finally, this also
2502 implements a new API, ap_show_mpm, which returns the MPM that was
2503 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
2505 *) Do not install the binaries from the support directory twice.
2506 [jun-ichiro hagino <itojun@iijlab.net>]
2508 *) The ap_f* functions should flush data to the filter that is passed
2509 in, not the the filter after the one passed in.
2510 [Ryan Morgan <rmorgan@covalent.net>]
2512 *) Make ab work again by changing its native types to apr types and formats.
2513 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2515 *) Move the byterange filter and all of the supporting functions back
2516 to the HTTP module. The byterange filter turned out to be very
2517 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
2519 *) Make clean, distclean, and extraclean consistently according to the
2520 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2522 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
2523 This may have been causing problems stopping processes in the threaded
2526 *) Fix content-length in mod_negotiation to a long int representation.
2529 *) Remove BindAddress from the default config file.
2530 [giles@nemeton.com.au]
2532 *) Allow module authors to add a module to their Apache build using
2533 --with-module, without re-running buildconf. The syntax is:
2534 --with-module=module_type:/path/to/module.c
2535 The configure script will copy the module.c file to
2536 modules/module_type, and it will be added to the relevant Makefiles.
2537 currently, this only works for static modules. [Ryan Bloom]
2539 *) Changes required to make prefork clean up idle children properly.
2540 There was a window during which a starting worker deadlocks when
2541 an idle cleanup arrives before it completes init. Apache then keeps
2542 trying to cleanup the same deadlocked worker forever (until higher
2543 pids come along, but it still will never reduce below the deadlocked
2544 pid). Thus the number of children would not reduce to the correct
2545 idle level. [Paul J. Reder]
2547 Changes with Apache 2.0.16
2549 *) Change the default installation directory to /usr/local/apache2,
2550 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
2552 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
2555 *) Get MaxRequestsPerChild working with the Windows MPM.
2558 *) Make generic hooks to work, with mod_generic_hook_import/export
2559 experimental modules. [Ben Laurie, Will Rowe]
2561 *) Fix segfaults for configuration file syntax errors such as
2562 "<Directory>" followed by "</Directory" and
2563 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
2565 *) Cleanup the --enable-layout option of configure. This makes
2566 us use a consistent location for the config.layout file, and it
2567 makes configure more portable.
2568 [jun-ichiro hagino <itojun@iijlab.net>]
2570 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
2571 csv/gnuplot format, rudimentary ssl support and various other tweaks
2572 to make results more true to what is measured. The upshot of this it
2573 turns out that 'ab' has often underreported the true performance of
2574 apache. Often by a order of magnitude :-) See talk/paper of Sander
2575 Temme at April ApacheCon 2001 for details.
2576 [Dirk-Willem van Gulik]
2578 *) Clean up mod_cgid's temporary request pool. Besides fixing a
2579 storage leak this ensures that some unnecessary pipes are closed.
2582 *) Performance: Add quick_handler hook. This hook is called at the
2583 very beginning of the request processing before location_walk,
2584 translate_name, etc. This hook is useful for URI keyed content
2585 caches like Mike Abbott's Quick Shortcut Cache.
2588 *) top_module global variable renamed to ap_top_module [Perl]
2590 *) Move ap_set_last_modified to the core. This is a potentially
2591 controversial change, because this is kind of HTTP specific. However
2592 many protocols should be able to take advantage of this kind of
2593 information. I expect that headers will need one more layer of
2594 indirection for multi-protocol work, but this is a small step in
2595 the right direction. [Ryan Bloom]
2597 *) Enable mod_status by default. This matches what Apache 1.3 does.
2600 *) Add a ScriptSock directive to the default config file. This is
2601 only enabled when mod_cgid is used.
2602 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2604 Changes with Apache 2.0.15
2606 *) Untangled the buildconf script and eliminated the need for build's
2607 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
2608 libtool muck that is now under srclib/apr/build. [Roy Fielding]
2610 *) Win32: Don't accept more connections than we have worker threads
2614 *) Fix bug in the Unix threaded.c MPM that allowed child processes
2615 to fork() new child processes.
2618 *) Fix a major security problem with double-reverse lookup checking.
2619 Previously, a client connecting over IPv4 would not be matched
2620 properly when the server had an IPv6 listening socket. PR #7407
2621 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
2623 *) Change the way the beos MPM handles polling to allow it to stop and
2624 restart. Problem was the sockets being polled were being reset by
2625 the select call, so once it had accepted a connection it was no
2626 longer listening on the UDP socket we use for shutdown instructions.
2627 APR needs to be altered, patch on it's way. [David Reid]
2629 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
2630 on error exit from ap_getline(). Some other code got upset because
2631 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
2633 *) Handle ap_discard_request_body() being called more than once.
2634 [Greg Ames, Jeff Trawick]
2636 *) Get rid of an inadvertent close of file descriptor 2 in
2637 mod_mime_magic. [Greg Ames, Jeff Trawick]
2639 *) Add a hook, create_request. This hook allows modules to modify
2640 a request while it is being created. This hook is called for all
2641 request_rec's, main request, sub request, and internal redirect.
2642 When this hook is called, the the r->main, r->prev, r->next
2643 pointers have been set, so modules can determine what kind of
2644 request this is. [Ryan Bloom]
2646 *) Cleanup the build process a bit more. The Apache configure
2647 script no longer creates its own helper scripts, it just
2649 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2651 *) Stop the forced downgrade of the connection to HTTP/1.0 for
2652 proxy requests. [Graham Leggett]
2654 *) Avoid using sscanf to determine the HTTP protocol number in
2655 the common case because sscanf is a performance hog. From
2656 Mike Abbot's Accelerating Apache patch number 6.
2657 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
2659 *) Fix a security exposure in mod_access. Previously when IPv6
2660 listening sockets were used, allow/deny-from-IPv4-address rules
2661 were not evaluated properly (PR #7407). Also, add the ability to
2662 specify IPv6 address strings with optional prefix length on Allow
2663 and Deny. [Jeff Trawick]
2665 *) Enhance rotatelogs so that a UTC offset can be specified, and
2666 the logfile name can be formatted using strftime(3). (Brought
2667 forward from 1.3.) [Ken Coar]
2669 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
2670 DuplicateHandle on an IOCompletionPort (a practice which
2671 MS "discourages"). The new model does not rely on associating
2672 the completion port with the listening sockets, thus the
2673 completion port can be completely managed within the child
2674 process. A dedicated thread accepts connections off the network,
2675 then calls PostQueuedCompletionStatus() to wake up worker
2676 threads blocked on the completion port.
2679 *) Bring forward the --suexec-umask option which allows the
2680 builder to preset the umask for suexec processes. [Ken Coar]
2682 *) Add a -V flag to suexec, which causes it to display the
2683 compile-time settings with which it was built. (Only
2684 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
2686 *) Mod_include should always unset the content-length if the file is
2687 going to be passed through send_parsed_content. There is no to
2688 determine if the content will change before actually scanning the
2689 entire content. It is far safer to just remove the C-L as long
2690 as we are scanning it. [Ryan Bloom]
2692 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
2693 request and not Proxy-Authenticate.
2694 [Graham Leggett <minfrin@sharp.fm>]
2696 Changes with Apache 2.0.14
2698 *) Fix content-length computation. We ONLY compute a content-length if
2699 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
2700 or we already have all the data. [Ryan Bloom]
2702 *) Report unbounded containers in the config file. Previously, a typo
2703 in the </container> directive could result in the rest of the config
2704 file being silently ignored, with undesired defaults used.
2707 *) Make the old_write filter use the ap_f* functions for the buffering.
2710 *) Move more code from the http module into the core server. This
2711 is core code, basically the default handler, the default input
2712 and output filters, and all of the core configuration directives.
2713 All of this code is required in order for the server to work, with or
2714 without HTTP. The server is closer to working without the HTTP
2715 module, although there is still more to do. [Ryan Bloom]
2717 *) Fix a number of SGI compile warnings throughout the server. Fix some
2718 bad parameters to apr_bucket_read(). Fix a bad statement in
2719 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
2720 consistently; we were mixing apr_time_t and time_t in invalid ways
2721 before. In load_file(), call apr_dso_error() instead of
2722 apr_strerror() so that we get a more specific string on some platforms.
2723 PR #6980 [Jeff Trawick]
2725 *) Allow modules to query the MPM about it's execution profile. This
2726 query API can and should be extended in the future, but for now,
2727 max_daemons, and threading or forking is a very good start.
2728 [Jon Travis <jtravis@covalent.net>]
2730 *) Modify mod_include to send blocks of data no larger than 9k.
2731 Without this, mod_include will wait until the whole file is parsed,
2732 or the first tag is found to send any data to the client.
2733 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2735 *) Fix mod_info, so that <Directory> and <Location> directives are
2736 not displayed twice when displaying the current configuration.
2737 [Ryan Morgan <rmorgan@covalent.net>]
2739 *) Add config directives to override DEFAULT_ERROR_MSG and
2740 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
2741 [Dan Rench <drench@xnet.com>]
2743 *) Get mod_info building and loading on Win32. [William Rowe]
2745 *) Begin to move protocol independant functions out of mod_http. The goal
2746 is to have only functions that are HTTP specific in the http directory.
2749 Changes with Apache 2.0.13
2751 *) Don't assume that there will always be multiple calls to the byterange
2752 filter. It is possible that we will need to do byteranges with only
2753 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
2755 *) Move the error_bucket definition from the http module to the
2756 core server. Every protocol will need this ability, not just
2759 Changes with Apache 2.0.12
2761 *) Modify mod_file_cache to save pre-formatted strings for
2762 content-length and last-modified headers for performance.
2763 [Mike Abbot <mja@trudge.engr.sgi.com>]
2765 *) Namespace protect IOBUFSIZ since it is exposed in the API.
2766 [Jon Travis <jtravis@covalent.net>]
2768 *) Use "Basic" authentication instead of "basic" in ab, as the spec
2769 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
2771 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
2772 without ever filling it out. This fixes PR 7271.
2773 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
2774 Cliff Woolley <cliffwoolley@yahoo.com>]
2776 *) Add a couple of GCC attribute tags to printf style functions.
2777 [Jon Travis <jtravis@covalent.net>]
2779 *) Add the correct language tag for interoperation with the Taiwanese
2780 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
2782 *) Migrate the perchild MPM to use the new apr signal child, and
2783 APR thread functions. [Ryan Bloom]
2785 *) Close one copy of the CGI's stdout before creating the new process.
2786 The CGI will still have stdout, because we have already dup'ed it.
2787 This keeps Apache from waiting forever to send the results of a CGI
2788 process that has forked a long-lived child process.
2789 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2791 *) Remove the rest of the pthreads functions from the threaded MPM.
2792 This requires the APR support for a signal thread that was just
2795 *) Make mod_dir use a fixup for sending a redirect to the browser.
2796 Before this, we were using a handler, which doesn't make much
2797 sense, because the handler wasn't generating any data, it would
2798 either return a redirect error code, or DECLINED. This fits the
2799 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
2801 *) Make the threaded MPM use APR threads instead of pthreads.
2804 *) Get mod_tls to the point where it actually appears to work in all cases.
2807 *) implement --enable-modules and --enable-mods-shared for "all" and
2808 "most". [Greg Stein]
2810 *) Move the threaded MPM to use APR locks instead of pthread locks.
2813 *) Rename mpmt_pthread to threaded. This is more in line with the
2814 fact that mpmt_pthread shouldn't be using pthreads directly, and
2815 it is a smaller name that doesn't tie into anything.
2818 *) Rename the module structures so that the exported symbol matches
2819 the file name, and it is easier to automate the installation
2820 process (generating LoadModule directives from the module filenames).
2823 *) Remove the coalesce filter. With the ap_f* functions, this filter
2824 is no longer needed. [Ryan Bloom]
2826 Changes with Apache 2.0.11
2828 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
2829 added feature of allowing a uid/gid per child process. If no
2830 uid/gid is specified, then Perchild behaves exactly like dexter.
2833 *) Get perchild building again. [Ryan Bloom]
2835 *) Don't disable threads just because we are using the prefork MPM.
2836 If somebody wants to compile without threads, they must now add
2837 --disable-threads to the configure command line. [Ryan Bloom]
2839 *) Begin to move the calls to update_child_status into common code, so
2840 that each individual MPM does not need to update the scoreboard itself.
2843 *) Allow mod_tls to compile under Unix boxes where openssl has been
2844 installed to the system include files.
2845 [Gomez Henri <new-httpd@slib.fr>]
2847 *) Cleanup the mod_tls configure process. This should remove any need
2848 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
2849 configure doesn't check that yet. [Ryan Bloom]
2851 *) Add a very early prototype of SSL support (in mod_tls.c). It is
2852 vital that you read modules/tls/README before attempting to build
2855 *) Fix a potential seg fault on all platforms. David Reid fixed this
2856 on BEOS, but the problem could happen anywhere, so we don't want
2857 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
2859 *) Add new LogFormat directive, %D, to log time it takes to serve a
2860 request in microseconds. [Bill Stoddard]
2862 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
2863 SetOutputFilter. This corresponds nicely with the other Set
2864 directives, which operate on containers while the Add* directives
2865 tend to work directly on extensions. [Ryan Bloom]
2867 *) Cleanup the header handling a bit. This uses the apr_brigade_*
2868 functions for the buffering so that we don't need to compute
2869 the length of the headers before we actually create the header
2870 buffer. [Ryan Bloom]
2872 *) Allow filters to buffer data using the ap_f* functions. These have
2873 become macros that resolve directly to apr_brigade_*.
2876 *) Get the Unix MPM's to do a graceful restart again. If we are going
2877 to register a cleanup with ap_cleanup_scoreboard, then we have to
2878 kill the cleanup with the same function, and that function can't be
2879 static. [Ryan Bloom]
2881 *) Install all required header files. Without these, it was not
2882 possible to compile some modules outside of the server.
2885 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
2886 forward from 1.3 to 2.0, we missed a single line, which broke regex
2887 aliases. [Ryan Bloom]
2889 *) We have a poor abstraction in the protocol. This is a temporary
2890 hack to fix the bug, but it will need to be fixed for real. If
2891 we find an error while sending out a custom error response, we back
2892 up to the first non-OK request and send the data. Then, when we send
2893 the EOS from finalize_request_protocol, we go to the last request,
2894 to ensure that we aren't sending an EOS to a request that has already
2895 received one. Because the data is sent on a different request than
2896 the EOS, the error text never gets sent down the filter stack. This
2897 fixes the problem by finding the last request, and sending the data
2898 with that request. [Ryan Bloom]
2900 *) Make the server status page show the correct restart time, and
2901 thus the proper uptime. [Ryan Bloom]
2903 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
2904 should reduce the amount of duplicate code that is required to
2905 create CGI processes.
2906 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2908 *) ap_new_connection() closes the socket and returns NULL if a socket
2909 call fails. Usually this is due to a connection which has been
2910 reset. [Jeff Trawick]
2912 *) Move the Apache version information out of httpd.h and into release.h.
2913 This is in preparation for the first tag with the new tag and release
2914 system. [Ryan Bloom]
2916 *) Begin restructuring scoreboard code to enable adding back in
2917 the ability to use IPC other than shared memory.
2918 Get mod_status working on Windows again. [Bill Stoddard]
2920 *) Make mod_status work with 2.0. This will work for prefork,
2921 mpmt_pthread, and dexter. [Ryan Bloom]
2923 *) Correct a typo in httpd.conf.
2924 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
2926 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
2928 *) Get the correct IP address if ServerName isn't set and we can't
2929 find a fully-qualified domain name at startup.
2930 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
2932 *) Make mod_cgid work with SuExec. [Ryan Bloom]
2934 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
2935 'extra' stat's for user/group since they should never occur, and now
2936 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
2937 volumes. [William Rowe]
2939 *) Adopt apr features to simplify mod_includes. This changes the
2940 behavior of the USER_NAME variable, unknown uid's are now reported
2941 as USER_NAME="<unknown>" rather than the old user#000 result.
2942 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
2944 *) Adopt apr features for simplifing mod_userdir, and accept the new
2945 Win32/OS2 exceptions without hiccuping. [William Rowe]
2947 *) Replace configure --with-optim option by using and saving the
2948 environment variable OPTIM instead. This is needed because configure
2949 options do not support multiple flags separated by spaces.
2952 *) Fix some byterange handling. If we get a byte range that looks like
2953 "-999999" where that is past the end of the file, we should return
2954 a PARTIAL CONTENT status code, and return the whole file as one big
2955 byterange. This matches the 1.3 handling now. [Ryan Bloom]
2957 *) Make the error bucket a real meta-data bucket. This means that the
2958 bucket length is 0, and a read returns NULL data. If one of these
2959 buckets is passed down after the headers are sent, this data will
2960 just be ignored. [Greg Stein]
2962 *) The prefork MPM wasn't killing child processes correctly if a restart
2963 signal was received while the process was serving a request. The child
2964 process would become the equivalent of a second parent process. If
2965 we break out of the accept loop, then we need to do die after cleaning
2966 up after ourselves. [Ryan Bloom]
2968 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
2969 restarts. [Ryan Bloom]
2971 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
2972 the most optimal APR_FINFO_wanted bits. This spares Win32 from
2973 performing very expensive owner, group and permission lookups
2974 and allows the server to function until these apr_finfo_t fields
2975 are implemented under Win32. [William Rowe]
2977 *) Support for typedsafe optional functions - that is functions exported by
2978 optional modules, which, therefore, may or may not be present, depending
2979 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
2980 for sample code. [Ben Laurie]
2982 *) filters can now report an HTTP error to the server. This is done
2983 by sending a brigade where the first bucket is an error_bucket.
2984 This bucket is a simple bucket that stores an HTTP error and
2985 a string. Currently the string is not used, but it may be needed
2986 to output an error log. The http_header_filter will find this
2987 bucket, and output the error text, and then return
2988 AP_FILTER_ERROR, which informs the server that the error web page
2989 has already been sent. [Ryan Bloom]
2991 *) If we get an error, then we should remove all filters except for
2992 those critical to serving a web page. This fixes a bug, where
2993 error pages were going through the byterange filter, even though
2994 that made no sense. [Ryan Bloom]
2996 *) Relax the syntax checking of Host: headers in order to support
2997 iDNS. PR#6635 [Tony Finch]
2999 *) Cleanup the byterange filter to use the apr_brigade_partition
3000 and apr_bucket_copy functions. This removes a lot of very messy
3001 code, and hopefully makes this filter more stable.
3004 *) Remove AddModule and ClearModuleList directives. Both of these
3005 directives were used to ensure that modules could be enabled
3006 in the correct order. That requirement is now gone, because
3007 we use hooks to ensure that modules are in the correct order.
3010 *) When SuExec is specified, we need to add it to the list of
3011 targets to be built. If we don't, then any changes to the
3012 configuration won't affect SuExec, unless 'make suexec' is
3013 specifically run. [Ryan Bloom]
3015 *) Cleaned out open_file from mod_file_cache, as apr now accepts
3016 the APR_XTHREAD argument to open a file for consumption by
3017 parallel threads on win32. [William Rowe]
3019 *) Correct a bug in determining when we follow symlinks. The code
3020 expected a stat -1 result, not an apr_status_t positive error.
3021 Also check if the APR_FINFO_USER fields are valid before we
3022 follow the link. [William Rowe]
3024 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
3025 mpm_common.c. These functions are only valid on some platforms,
3026 so they should not be in the main-line code. [Ryan Bloom]
3028 *) Remove ap_chdir_file(). This function is not thread-safe,
3029 and nobody is currently using it. [Ryan Bloom]
3031 *) Do not try to run make depend if there are no .c files in the
3032 current directory, doing so makes `make depend` fail.
3035 *) Update highperformance.conf to work with either prefork or
3036 pthreads mpms. [Greg Ames]
3038 *) Stop checking to see if this is a pipelined request if we know
3039 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
3040 This keeps us from making an extra read call when serving a 1.0
3041 request. [Ryan Bloom and Greg Stein]
3043 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
3044 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
3045 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
3047 *) Fix the RFC number mentioned when complaining about a missing
3048 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
3050 *) Fix an endless loop in ab which occurred when ab was posting
3051 and the server dropped the connection unexpectedly.
3054 *) Fix a segfault while handling request bodies in ap_http_filter().
3055 This problem has been seen with mod_dav usage as well as with
3056 requests where the body was just being discarded. [Jeff Trawick]
3058 *) Some adjustment on the handling and automatic setting (via
3059 hints.m4) of various compilation flags (eg: CFLAGS). Also,
3060 add the capability to specify flags (NOTEST_CFLAGS and
3061 NOTEST_LDFLAGS) which are used to compile Apache, but
3062 not used during the configuration process. Useful for
3063 flags like "-Werror". [Jim Jagielski]
3065 *) Stop using environment variables to force debug mode or
3066 no detach. We now use the -D command line argument to
3067 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
3068 [Greg Stein, Ryan Bloom]
3070 *) Change handlers to use hooks. [Ben Laurie]
3072 *) Stop returning copies of filenames from both apr_file_t and
3073 apr_dir_t. We pstrdup the filenames that we store in the
3074 actual structures, so we don't need to pstrdup the strings again.
3077 *) mod_cgi: Fix some problems where the wrong error value was being
3078 traced. [Jeff Trawick]
3080 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
3083 *) Add generic hooks. [Ben Laurie]
3085 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
3087 *) Fix a segfault caused by mod_ext_filter when the external filter
3088 program does not exist. [Jeff Trawick]
3090 *) Fix an output truncation error when on an HTTP >= 1.0 request an
3091 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
3092 was served through mod_charset_lite (or anything else that would
3093 create a transient bucket in this size range). ap_bucket_make_heap()
3094 silently failed (fixed), transient_setaside() discovered it, but
3095 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
3097 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
3098 is that some browsers send extra lines at the end of POST requests, and
3099 we don't want to delay sending data back to the user just because the
3100 browser isn't well behaved. [Ryan Bloom]
3102 *) Get SuEXEC working again. We can't send absolute paths to suExec
3103 because it refuses to execute those programs. SuEXEC also wasn't
3104 always recognizing configuration changes made using the autoconf
3107 *) Allow the buildconf process to find the config.m4 files in the correct
3108 order. Basically, we can now name config.m4 files as config\d\d.m4,
3109 and we will sort them correctly when inserting them into the build
3110 process. [Ryan Bloom]
3112 *) Get mod_cgid to use apr calls for creating the actual CGI process.
3113 This also allows mod_cgid to use ap_os_create_priviledged_process,
3114 thus allowing for SuExec execution from mod_cgid. Currently, we do
3115 not support everything that standard SuExec supports, but at least
3116 it works minimally now. [Ryan Bloom]
3118 *) Allow SuExec to be configured from the ./configure command line.
3121 *) Update some of the docs in README and INSTALL to reflect some of
3122 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
3124 *) If we get EAGAIN returned from the call to apr_sendfile, then we
3125 need to call sendfile again. This gets us serving large files
3126 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
3128 *) Get the support programs building cleanly again.
3129 [Cliff Woolley <cliffwoolley@yahoo.com>]
3131 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
3132 current directory logic now backs up over bin/ to determine the
3133 server root from the Apache.exe path.
3135 *) Apache/Win32 now follows the standard conventions of mod_foo.so
3136 loadable modules, dynamic libs are all named libfoo.dll, and the
3137 makefile.win populates the include, lib and libexec directories.
3139 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
3140 Apache gets IPv6 listening sockets by default. Additionally, the
3141 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
3142 numeric address strings (e.g., "Listen [fe80::1]:8080").
3145 *) Modify the install directory layout. Modules are now installed in
3146 modules/. Shared libraries should be installed in libraries/, but
3147 we don't have any of those on Unix yet. All install directories
3148 are modifyable at configure time. [Ryan Bloom]
3150 *) Install all header files in the same directory on Unix. [Ryan Bloom]
3152 *) Get the functions in server/linked into the server, regardless of
3153 which modules linked into the server. This uses the same hack
3154 for Apache that we use for APR and apr-util to ensure all of the
3155 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
3156 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
3157 the scripts a bit easier.
3160 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
3161 on the query, and remove IPv4 dependencies. [Jeff Trawick]
3163 *) Get all of the auth modules to the point that they will install and
3164 be loadable into the server. Our new build/install mechanism expects
3165 that all modules will have a common name format. The auth modules
3166 didn't use that format, so we didn't install them properly.
3169 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
3170 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
3172 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
3174 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
3175 after the end of the response. [Ryan Bloom]
3177 *) Get byterange requests working with responses that do not have a
3178 content-length. Because of the way byterange requests work, we have to
3179 have all of the data before we can actually do the byterange, so we
3180 can compute the content-length in the byterange filter.
3183 *) Get exe CGI's working again on Windows.
3186 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
3187 they keep track of whether or not their post config hook has been
3188 called before. Instead of a static variable (which is replaced when
3189 the DSO is loaded a second time), use userdata in the process pool.
3192 Changes with Apache 2.0a9
3194 *) Win32 now requires perl to complete the final install step for users
3195 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
3196 and installs the conf, htdocs and htdocs/manual directories.
3199 *) Make mod_include use a hash table to associate directive tags with
3200 functions. This allows modules to implement their own SSI tags easily.
3201 The idea is simple enough, a module can insert it's own tag and function
3202 combination into a hash table provided by mod_include. While mod_include
3203 parses an SSI file, when it encounters a tag in the file, it does a
3204 hash lookup to find the function that implements that tag, and passes
3205 all of the relevant data to the function. That function is then
3206 responsible for processing the tag and handing the remaining data back
3207 to mod_include for further processing.
3208 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3210 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
3211 fewer parameters: the local and remote socket addresses were removed
3212 from the parameter list because all required information is available
3213 via the APR socket. [Jeff Trawick]
3215 *) Distribution directory structure reorganized to reflect a
3216 normal source distribution with external install targets.
3219 *) The MPMs that need multiple segments of shared memory now create
3220 two apr_shmem_t variables, one for each shared memory allocation.
3221 the problem is that we can't determine how much memory will be required
3222 for shared memory allocations once we try to allocate more than one
3223 variable. The MM code automatically aligns the shared memory allocations,
3224 so we end up needing to pad the amount of shared memory we want based
3225 on how many variables will be allocated out of the shared memory segment.
3226 It is just easier to create a second apr_shmem_t variable, and two
3227 shmem memory blocks.
3230 *) Cleanup the export list a bit. This creates a single unified list of
3231 functions exported by APR. The export list is generated at configure
3232 time, and that list is then used to generate the exports.c file.
3233 Because of the way the export list is generated, we only export those
3234 functions that are valid on the platform we are building on.
3237 *) Enable logging the cookie with mod_log_config
3238 [Sander van Zoest <sander@covalent.net>]
3240 *) Fix a segfault in mod_info when it reaches the end of the configuration.
3243 *) Added lib/aputil/ as a placeholder for utility functions which are not
3244 specific to the Apache HTTP Server (but do not make sense with APR).
3245 The first utility is "apu_dbm": a set of functions to work with DBM
3246 files. This first version can be compiled for SDBM or GDBM databases.
3249 *) Complete re-write of mod_include. This makes mod_include a filter that
3250 uses buckets directly. This has now served the FAQ correctly.
3251 [Paul Reder <rederpj@raleigh.ibm.com>]
3253 *) Allow modules to specify the first filter in a sub_request when
3254 making the sub_request. This keeps modules from having to change the
3255 output_filter immediately after creating the sub-request, and therefore
3256 skip the sub_req_output_filter. [Ryan Bloom]
3258 *) Update ab to accept URLs with IPv6 literal address strings (in the
3259 format described in RFC 2732), and to build Host header fields in
3260 the same format. This allows IPv6 literal address strings to be
3261 used with ab. This support has been tested against Apache 1.3 with
3262 the KAME patch, but Apache 2.0 does not yet work with this format
3263 of the Host header field. [Jeff Trawick]
3265 *) Accomodate an out-of-space condition in the piped logs and the
3266 rotatelogs.c code, and no longer churn log processes for this
3267 condition. [Victor J. Orlikowski]
3269 *) Add support for partial writes with apr_sendfile() to core_output_filter.
3272 Changes with Apache 2.0a8
3274 *) Add a directive to mod_mime so that filters can be associated with
3278 *) Get multi-views working again. We were setting the path_info
3279 field incorrectly if we couldn't find the specified file.
3282 *) Fix 304 processing. The core should never try to send the headers
3283 down the filter stack. Always, just setup the table in the request
3284 record, and let the header filter convert it to data that is ready
3288 *) More fixes for the proxy. There are still bugs in the proxy code,
3289 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
3293 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
3296 *) APR: Add new apr_getopt_long function to handle long options.
3297 [B. W. Fitzpatrick <fitz@red-bean.com>]
3299 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
3300 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
3301 hostname resolution/address string parsing and building
3302 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
3303 of one of the apr_sockaddr_t structures for a socket. Change
3304 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
3306 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
3307 I have proxied pages with it, cleanup will commence soon.
3310 *) Make the proxy work with filters. This isn't perfect, because we
3311 aren't dealing with the headers properly. [Ryan Bloom]
3313 *) Do not send a content-length iff the C-L is 0 and this is a head
3314 request. [Ryan Bloom]
3316 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
3317 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
3319 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
3321 *) Get the default_handler to stop trying to deal with HEAD requests.
3322 The idea is to let the content-length filter compute the C-L before
3323 we try to send the data. If we can get the C-L correctly, then we
3324 should send it in the HEAD response.
3327 *) The Header filter can now determine if a body should be sent based
3328 on r->header_only. The general idea of this is that if we delay
3329 deciding to send the body, then we might be able to compute the
3330 content-length correctly, which will help caching proxies to cache
3331 our data better. Any handler that doesn't want to try to compute
3332 the content-length can just send an EOS bucket without data and
3333 everything will just work.
3336 *) Add the referer to the error log if one is available.
3337 [Markus Gyger <mgyger@itr.ch>]
3339 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
3340 change, the root of the configuration tree has been exposed to modules
3342 [Ryan Morgan <rmorgan@covalent.net>]
3344 *) Get the core_output_filter to use the bucket interface directly.
3345 This keeps us from calling the content-length filter multiple times
3346 for a simple static request.
3349 *) We are sending the content-type correctly now.
3350 [Ryan Bloom and Will Rowe]
3352 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
3353 a bogus bytes-sent value when the only thing being sent was trailers
3354 and writev() returned an error (or EAGAIN). [Jeff Trawick]
3356 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
3357 hints file to determine which platforms define
3358 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3361 *) APR: add apr_get_home_directory() [Jeff Trawick]
3363 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
3365 *) Not all platforms have INADDR_NONE defined by default. Apache
3366 used to make this check and define INADDR_NONE if appropriate,
3367 but APR needs the check too, and I suspect other applications will
3368 as well. APR now defines APR_INADDR_NONE, which is always a valid
3369 value on all platforms.
3370 [Branko Èibej <brane@xbc.nu>]
3372 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
3373 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
3375 *) Relax the syntax checking of Host: headers in order to support
3376 iDNS. PR#6635 [Tony Finch]
3378 *) When reading from file buckets we convert to an MMAP if it makes
3379 sense. This also simplifies the default handler because the
3380 default handler no longer needs to try to create MMAPs.
3383 *) BUFF has been removed from the main server. The BUFF code will remain
3384 in the code until it has been purged from the proxy module as well.
3387 *) Byteranges have been completely re-written to be a filter. This
3388 has been tested, and I believe it is working correctly, but it could
3389 doesn't work for the Adobe Acrobat plug-in. The output almost matches
3390 the output from 1.3, the only difference being that 1.3 includes
3391 a content-length in the response, and this does not.
3394 *) APR read/write functions and bucket read functions now operate
3395 on unsigned integers, instead of signed ones. It doesn't make
3396 any sense to use signed ints, because we return the error codes,
3397 so if we have an error we should report 0 bytes read or written.
3400 *) Always compute the content length, whether it is sent or not.
3401 The reason for this, is that it allows us to correctly report
3402 the bytes_sent when logging the request. This also simplifies
3403 content-length filter a bit, and fixes the actual byte-reporing
3404 code in mod_log_config.c
3407 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
3408 it says, because it was only used by EOS and FLUSH buckets. Since
3409 neither of those are required at the end of a brigade, this was
3410 really signifying FLUSH_THE_DATA, but that can be determined better
3411 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
3412 buckets now return a length of 0, which is actually the amount of data
3413 read, so they make more sense.
3416 *) Allow the core_output_filter to save some data past the end of a
3417 request. If we get an EOS bucket, we only send the data if it
3418 makes sense to send it. This allows us to pipeline request
3419 responses. As a part of this, we also need to allocate mmap
3420 buckets out of the connection pool, not the request pool. This
3421 allows the mmap to outlive the request.
3424 *) Make blocking and non-blocking bucket reads work correctly for
3425 sockets and pipes. These are the only bucket types that should
3426 have non-blocking reads, because the other bucket types should
3427 ALWAYS be able to return something immediately.
3430 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
3431 server, but use Ctrl+Break to initiate a graceful restart
3432 instead of duplicating behavior. [John Sterling]
3434 *) Patch mod_autoindex to set the Last-Modified header based on
3435 the directory's mtime, and add the ETag header. [William Rowe]
3437 *) Merge the 1.3 patch to add support for logging query string in
3438 such a way that "%m %U%q %H" is the same as "%r".
3441 *) Port three log methods from mod_log_config 1.3 to 2.0:
3442 CLF compliant '-' byte count, method and protocol.
3445 *) Add a new LogFormat directive, %c, that will log connection
3446 status at the end of the response as follows:
3447 'X' - connection aborted before the response completed.
3448 '+' - connection may be kept-alive by the server.
3449 '-' - connection will be closed by the server.
3452 *) Expand APR for WinNT to fully accept and return utf-8 encoded
3453 Unicode file names and paths for Win32, and tag the Content-Type
3454 from mod_autoindex to reflect that charset if the the feature
3455 macro APR_HAS_UNICODE_FS is true. [William Rowe]
3457 *) Compute the content length (and add appropriate header field) for
3458 the response when no content length is available and we can't use
3459 chunked encoding. [Jeff Trawick]
3461 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
3462 so that content input filters get dechunked data when using
3463 the default handler. Also removed REQUEST_CHUNKED_PASS.
3466 *) Add mod_ext_filter as an experimental module. This module allows
3467 the administrator to use external programs as filters. Currently,
3468 only filtering of output is supported. [Jeff Trawick]
3470 *) Most Apache functions work on EBCDIC machines again, as protocol
3471 data is now translated (again). [Jeff Trawick]
3473 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
3474 the EBCDIC support. They are noops on ASCII machines, so this
3475 type of translation doesn't have to be surrounded by #ifdef
3476 CHARSET_EBCDIC. [Jeff Trawick]
3478 *) Fix mod_include. tag commands work again, and the server will
3479 send the FAQ again. This also allows mod_include to set aside
3480 buckets that include partial buckets.
3481 [Ryan Bloom and David Reid]
3483 *) Add suexec support back. [Manoj Kasichainula]
3485 *) Lingering close now uses the socket directly instead of using
3486 BUFF. This has been tested, but since all we can tell is that it
3487 doesn't fail, this needs to be really hacked on.
3490 *) Allow filters to modify headers and have those headers be sent to
3491 the client. The idea is that we have an http_header filter that
3492 actually sends the headers to the network. This removes the need
3493 for the BUFF to send headers.
3496 *) Charset translation: mod_charset_lite handles translation of
3497 request bodies. Get rid of the xlate version of ap_md5_digest()
3498 since we don't compute digests of filtered (e.g., translated)
3499 response bodies this way anymore. (Note that we don't do it at
3500 all at the present; somebody needs to write a filter to do so.)
3503 *) Input filters and ap_get_brigade() now have a input mode parameter
3504 (blocking, non-blocking, peek) instead of a length parameter.
3507 *) Update the mime.types file to the registered media types as
3508 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
3511 *) Namespace protect some macros declared in ap_config.h
3514 *) Support HTTP header line folding with input filtering.
3517 *) Mod_include works again. This should still be re-written, but at
3518 least now we can serve an SHTML page again.
3521 *) Begin to remove BUFF from the core. Currently, we keep a pointer
3522 to both the BUFF and the socket in the conn_rec. Functions that
3523 want to use the BUFF can, functions that want to use the socket,
3524 can. They point to the same place.
3527 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
3528 [Tomas "Ögren" <stric@ing.umu.se>]
3530 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
3531 associated pool goes away. (APR pipes on OS/2 were already had this
3532 logic.) This resolvs a fatal file descriptor leak with CGIs.
3535 *) The final line of the config file was not being read if there was
3536 no \n at the end of it. This was caused by apr_fgets returning
3537 APR_EOF even though we had read valid data. This is solved by
3538 making cfg_getline check the buff that was returned from apr_fgets.
3539 If apr_fgets return APR_EOF, but there was data in the buf, then we
3540 return the buf, otherwise we return NULL.
3543 *) Piped logs work again in the 2.0 series.
3546 *) Restore functionality broken by the mod_rewrite security fix:
3547 rewrite map lookup keys and default values are now expanded
3548 so that the lookup can depend on the requested URI etc.
3549 PR #6671 [Tony Finch]
3551 *) Tighten up the syntax checking of Host: headers to fix a
3552 security bug in some mass virtual hosting configurations
3553 that can allow a remote attacker to retrieve some files
3554 on the system that should be inaccessible. [Tony Finch]
3556 *) Add a pool bucket type. This bucket is used for data allocated out
3557 of a pool. If the pool is cleaned before the bucket is destroyed, then
3558 the data is converted to a heap bucket, allowing it to survive the
3562 *) Add a flush bucket. This allows modules to signal that the filters
3563 should all flush whatever data they currently have. There is no way
3564 to actually force them to do this, so if a filter ignores this bucket,
3565 that's life, but at least we can try with this.
3568 *) Add an output filter for sub-requests. This filter just strips the
3569 EOS bucket so that we don't confuse the main request's core output
3570 filter by sending multiple EOS buckets. This change also makes sub
3571 requests start to send EOS buckets when they are finished.
3574 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
3575 makes ap_bucket_destroy a return void, which is okay because it
3576 used to always return APR_SUCCESS, and nobody ever checked its
3577 return value anyway.
3578 [Cliff Woolley <cliffwoolley@yahoo.com>]
3580 *) Remove the index into the bucket-type table from the buckets
3581 structure. This has now been replaced with a pointer to the
3582 bucket_type. Also add some macros to test the bucket-type.
3585 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
3586 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
3587 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
3588 All _VAR_ flavors changes to _DATA to be absolutely clear.
3591 *) Add support for /, //, //servername and //server/sharename
3592 parsing of <Directory> blocks under Win32 and OS2.
3593 [Tim Costello, William Rowe, Brian Harvard]
3595 *) Remove the function pointers from the ap_bucket type. They have been
3596 replaced with a global table. Modules are allowed to register bucket
3597 types and use then use those buckets.
3600 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
3601 once we finish writing the request body to the cgi child process;
3602 otherwise, the client doesn't hit EOF on stdin. Small request bodies
3603 worked without this change (for reasons I don't understand), but large
3604 ones didn't. [Jeff Trawick]
3606 *) Remove file bucket specific information from the ap_bucket type.
3607 This has been moved to a file_bucket specific type that hangs off
3608 the data pointer in the ap_bucket type.
3611 *) Input filtering now has a third argument. This is the amount of data
3612 to read from lower filters. This argument can be -1, 0, or a positive
3613 number. -1 means give me all the data you have, I'll deal with it and
3614 let you know if I need more. 0 means give me one line and one line
3615 only. A positive number means I want no more than this much data.
3617 Currently, only 0 and a positive number are implemented. This allows
3618 us to remove the remaining field from the conn_rec structure, which
3622 *) Big cleanup of the input filtering. The goal is that http_filter
3623 understands two conditions, headers and body. It knows where it is
3624 based on c->remaining. If c->remaining is 0, then we are in headers,
3625 and http_filter returns a line at a time. If it is not 0, then we are
3626 in body, and http_filter returns raw data, but only up to c->remaining
3627 bytes. It can return less, but never more.
3628 [Greg Ames, Ryan Bloom, Jeff Trawick]
3630 *) mod_cgi: Write all of the request body to the child, not just what
3631 the kernel would accept on the first write. [Jeff Trawick]
3633 *) Back out the change that moved the brigade from the core_output_filters
3634 ctx to the conn_rec. Since all requests over a given connection
3635 go through the same core_output_filter, the ctx pointer has the
3639 *) Fix another bug in the send_the_file() read/write loop. A partial
3640 send by apr_send would cause unsent data in the read buffer to
3641 get clobbered. Complete making send_the_file handle partial
3642 writes to the network.
3645 *) Fix a couple of type fixes to allow compilation on AIX again
3646 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
3648 *) Fix bug in send_the_file() which causes offset to be ignored
3649 if there are no headers to send.
3652 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
3653 filter. Useful for supporting Windows 9* with a binary
3654 compiled on Windows NT.
3657 Changes with Apache 2.0a7
3659 *) Reimplement core_output_filter to buffer/save bucket brigades
3660 across multiple calls to the core_filter. The brigade will be
3661 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
3662 thresholds are hit or the EOS bucket is received.
3665 *) Create experimental filter (buffer_filter) that coalesces bytes
3666 into one large buffer before invoking the next filter in the
3667 chain. This filter is particularly useful with the current
3668 implementation of mod_autoindex when it inserted above the
3669 chunk_filter. mod_autoindex generates a lot of brigades that
3670 containing buckets holding just a few bytes each. The
3671 buffer_filter coalesces these buckets into a single large bucket.
3674 *) Add apr_sendfile() support into the core_output_filter.
3677 *) Add apr_sendv() support into the core_output_filter.
3680 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
3681 [Mike Abbott <mja@sgi.com>]
3683 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
3684 make much sense, because Apache uses buckets instead of BUFFs now.
3687 *) send_the_file now falls back to a read/write loop on platforms that
3688 do not have sendfile.
3689 [Ryan Bloom and Brian Havard]
3691 *) Install apachectl correctly, and substitute the proper values so
3692 that it works again. [Ryan Bloom]
3694 *) Better(??) handle platforms that lack sendfile().
3697 *) APR now has UUID generation/formatting/parsing support.
3700 *) Begin the http_filter. This is an input filter that understands
3701 the absolute basic amount required to parse an HTTP Request. The
3702 goal is to be able to split headers from request body before passing
3703 the data back to the other filters.
3706 *) Bring forward from 1.3.13 the config directory implementation
3709 *) install apxs if it is created
3712 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
3713 conversions. [William Rowe]
3715 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
3716 ap_add_output_filter(). [Jeff Trawick]
3718 *) Multiple build and configuration fixes
3721 -add datadir and localstatedir substitutions
3723 -fix logfilename misspelling
3724 -fix evaluation of installation dir variables and
3725 -replace $foobar by $(foobar) to be usefull in the makefile
3729 -add rules for cross-compiling in rules.mk. Okay, rule to check for
3730 $CC_FOR_BUILD is still missing
3731 -use CHECK_TOOL instead of CHECK_PROG for ranlib
3732 -add missing "AR=@AR@" to severaly Makefile.in's
3733 -cache result for "struct rlimit"
3734 -compile all helper programs with native and cross compiler
3735 and use the native version to generate header file
3736 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3738 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
3740 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3742 *) Fix a bug where a client which only sends \n to delimit header
3743 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
3744 message. Start working on ebcdic co-existance with input
3746 [William Rowe, Greg Ames]
3748 *) If mod_so is enabled in the server always create libexec, even
3749 if there are no modules installed in this directory. This is a
3750 requirement for APXS to work correctly.
3753 *) Connection oriented output filters are now stored in the
3754 conn_rec instead of the request_rec. This allows us to add the
3755 output filter in the pre-connection phase instead of the
3756 post_read_request phase, which keeps us from trying to write an
3757 error page before we have a filter to write to the network.
3758 [Ryan Bloom, Jeff Trawick, and Greg Ames]
3760 *) Cleaning up an mmap bucket no longer deletes the mmap. An
3761 mmap can be used across multiple buckets (default_handler with
3762 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
3763 the mmap itself can't be associated with the bucket.
3766 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
3769 *) Radical surgery to improve mod_isapi support under Win32.
3770 Includes a number of newer ServerSupportFunction calls, support
3771 for ReadClient (in order to retrieve POSTs greater than 48KB),
3772 and general bug fixes to more reliably load ISAPI .dll's and
3773 prevent leaking handle resources. Note: There are still
3774 discrepancies between IIS's and Apache's ServerVariables, and
3775 async calls are still not supported. Additional warnings are
3776 logged to facilitate debugging of unsupported ISAPI calls.
3779 *) Add input filtering to Apache. The basic idea for the input
3780 filters is the same as the ideas for output filters. The biggest
3781 difference is that instead of calling ap_pass_brigade, ap_get_brigade
3782 should be called, and the order of execution for the filter itself is
3783 different. When writing an output filter, a brigade is passed in,
3784 and filters operate directly on that brigade, when done, they call
3785 ap_pass_brigade. Input filters are the exact opposite. Because input
3786 is not a push operation, filters first call ap_get_brigade. When this
3787 function returns, the input filter will be left with a valid brigade.
3788 The input filter should then operate on the brigade, and return.
3791 *) Fix building on BSD/OS using its native make. The build system
3792 falls back to the BSD .include directive on that host platform.
3795 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
3796 SHA1 and plaintext password encodings. Make feature tests a
3797 bit more flexible. [William Rowe]
3799 *) Charset translation: mod_charset_lite handles output content
3800 translation in a filter. mod_charset_lite no longer ignores
3801 subrequests. A bunch of cruft related to BUFF's support for
3802 translating request and response bodies was removed.
3805 *) Move the addition of the CORE filter to the post_read_request
3806 hook in http_core.c. This removes the need to add the filter in
3807 multiple places and allows for an SSL module to be added much
3808 simpler. [Ryan Bloom]
3810 *) Fix a security problem that affects certain configurations of
3811 mod_rewrite. If the result of a RewriteRule is a filename that
3812 contains expansion specifiers, especially regexp backreferences
3813 $0..$9 and %0..%9, then it may be possible for an attacker to
3814 access any file on the web server. [Tony Finch]
3816 *) Fix a bug where errors that are detected during early request parsing
3817 don't produce visible HTTP error messages at the browser, because
3818 the core_filter wasn't present. [Greg Ames]
3820 *) Provide apr_socklen_t as a portability aid.
3821 [Victor J. Orlikowski]
3823 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
3824 as well as a comment arg to the add, adduser and update cmds.
3825 update allows the user to clear or preserve pw/groups/comment.
3826 Fixed a bug in dbmmanage that prevented the check option from
3827 parsing a password followed by :group... text. Corrected the
3828 seed calcualation for Win32 systems, and added -lsdbm support.
3831 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
3834 *) Avoid a segfault when parsing .htaccess files. An
3835 uninitialized tree pointer was passed to ap_build_config().
3838 *) Change the way that inet_addr & inet_network are checked for
3839 in APR's configure process to allow BeOS BONE to correctly
3840 find them. With this change BeOS BONE now builds from source
3841 with no problems. [David Reid]
3843 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
3844 the end of the parameters to execve() was stored in the wrong
3845 location, overlaying the storage beyond the newargs[] array and
3846 also passing uninitialized storage to execve(), which would
3847 sometimes fail with EFAULT. [Jeff Trawick]
3849 *) Fix a bug parsing configuration file containers. With a sequence
3850 like this in the config file
3852 <IfModule mod_kilroy.c>
3855 <IfModule mod_lovejoy.c>
3860 the second container would be terminated at the blank line due to
3861 sediment in the buffer from reading the prior </IfModule> and an
3862 error message would be generated for the real </IfModule> for the
3863 second container. Also due to this problem, any two characters
3864 could be used for "</" in the close of a container.
3867 *) ap_add_filter prototype changed to remove the ctx pointer. The
3868 pointer still remains in the filter structure, but it can not be
3869 a part of the ap_add_filter prototype. The reason is that when
3870 the core uses AddFilter to add a filter to the stack it doesn't
3871 know how to allocate the ctx pointer, or even how much memory should
3872 be allocated. The filters will have to be responsible for allocating
3873 the ctx memory when they need it.
3876 *) Add an AddFilter directive. This directive takes a list of filters
3877 that should be activated for the requested resource.
3880 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
3881 some other platforms). [Jeff Trawick]
3883 *) Modify mod_include to be a filter. Currently, it has only been tested
3884 on actual files, but it should work for CGI scripts too.
3887 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
3888 writes. apr_flush() for Unix: handle interrupted writes.
3891 *) NameVirtualHost can now take "*" as an argument instead of
3892 an IP address. This allows you to create a purely name-based
3893 virtual hosting server that does not have any IP addresses in
3894 the configuration file and which ignores the local address
3895 of any connections. PR #5595, PR #4455 [Tony Finch]
3897 *) Fix some compile warnings in mod_mmap_static.c
3898 [Mike Abbott <mja@sgi.com>]
3900 *) Fix chunking problem with CGI scripts. The general problem was that
3901 the CGI modules were adding an EOS bucket and then the core added an
3902 EOS bucket. The chunking filter finalizes the chunked response when it
3903 encounters an EOS bucket. Because two EOS buckets were sent, we
3904 finalized the response twice. The fix is to make sure we only send one
3905 EOS, by utilizing a flag in the request_rec.
3908 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
3909 and Win32. Previously, the first read from an apr_file_t set up via
3910 apr_put_os_file() would return a '\0'. [Jeff Trawick]
3912 *) Mod_cgid now creates a single element bucket brigade, with a pipe
3913 bucket, instead of using BUFF's and ap_r*.
3916 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
3917 [Mike Abbott <mja@sgi.com>]
3919 *) Remove ap_bopenf from buff code. This required modifying the file_cache
3920 code to use APR file's directly instead of going through BUFFs.
3923 *) Fix compile break on some platforms for mod_mime_magic.c
3924 [John K. Sterling <sterling@covalent.net>]
3926 *) Fix merging of AddDefaultCharset directive.
3927 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
3929 *) Minor revamp of the rlimit sections of code. We now test
3930 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
3931 is now "available" even if the platform doesn't support
3932 the rlimit family (it's just a noop though). [Jim Jagielski]
3934 *) Migrate the pre-selection of which MPM to use for specific
3935 platforms to hints.m4, which contains (or should contain)
3936 all platform specific "hints". [Jim Jagielski]
3938 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
3941 *) Add tables with non-string/binary values to APR.
3944 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
3947 *) Update PCRE to version 3.2. [Ryan Bloom]
3949 *) Change the way buckets' destroy functions are called so that
3950 they can be more directly used when changing the type of a
3951 bucket in place. [Tony Finch]
3953 *) Add generic support for reference-counting the resources used by
3954 buckets, and alter the HEAP and MMAP buckets to use it. Change
3955 the way buckets are initialised to support changing the type of
3956 buckets in place, and use it when setting aside TRANSIENT buckets.
3957 Change the implementation of TRANSIENT buckets so that it can be
3958 mostly shared with IMMORTAL buckets, which are now implemented.
3961 Changes with Apache 2.0a6
3963 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
3965 *) Add a chunking filter to Apache. This brings us one step closer
3966 to removing BUFF. [Ryan Bloom]
3968 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
3969 added to the stack is the last filter to be called. [Ryan Bloom]
3971 *) Apache 2.0 has been completely documented using Scandoc. The
3972 docs can be generated by running 'make docs'. [Ryan Bloom]
3974 *) Add filtered I/O to Apache. This is based on bucket brigades,
3975 Currently the buckets still use BUFF under the covers, but that
3976 should change quickly. The only currently written filter is the
3977 core filter which just calls ap_bwrite. [The Apache Group]
3979 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
3980 built with thread support. [Jeff Trawick]
3982 *) Abort configuration if --with-layout was specified and there's
3983 no layout definition file. [Ken Coar]
3985 *) Add support for '--with-port=n' option to configure. [Ken Coar]
3987 *) Add support for extension methods for the Allow response header
3988 field, and an API routine for accessing r->allowed and the
3989 list of extension methods in a unified manner. [Ken Coar]
3991 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
3992 [Rob Simonson <simo@us.ibm.com>]
3994 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
3995 APACHE_XLATE builds. [Jeff Trawick]
3997 *) A configuration file parsing problem was fixed. When the
3998 configuration file started with an IfModule/IfDefine container,
3999 only the last statement in the container would be retained.
4002 Changes with Apache 2.0a5
4004 *) Perchild is serving pages after passing them to different child
4005 processes. There are still a lot of bugs, but this does work. I
4006 have made requests against the same installation of Apache, and had
4007 different servers use different user IDs to serve the responses.
4008 This change moves to using socketpair instead of an AF_UNIX socket.
4011 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
4012 It can't seem to pass between child processes yet, but I think we
4013 are closer now than before. This moves us back to using Unix
4014 Domain Sockets. [Ryan Bloom]
4016 *) libapr functions and types renamed with apr_ prefix.
4017 #include "apr_compat.h" for 1.3.x backwards compat
4020 *) Fix problems with APR sockaddr handling on Win32. It didn't always
4021 return the right information on the local socket address.
4022 [Gregory Nicholls <gnicholls@level8.com>]
4024 *) ap_recv() on Win32: Set bytes-read to 0 on error.
4025 [Gregory Nicholls <gnicholls@level8.com>]
4027 *) Add an option to not detach from the controlling terminal without
4028 going into single process mode. This allows for much easier
4029 debugging of the process startup code. [Ryan Bloom]
4031 *) ab: don't use perror() to report the failure of an APR function.
4034 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
4035 scoreboard on graceful restarts.
4038 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
4039 An invalid ap_proc_t was passed to ap_create_process().
4042 *) Allow modules to register filters. Those filters are still
4043 never called, but this is a step in the right direction.
4044 [Ryan Bloom and Greg Stein]
4046 *) Register the mod_cgid daemon process for cleanup so that it is
4047 killed at termination if it does not die when the parent gets
4048 SIGTERM. This change is to fix occasional problems where the
4049 process stays around. Bugs in similar logic in mod_rewrite and
4050 mod_include were also fixed. [Jeff Trawick]
4052 *) Fix a bug in the time handling. Basically, we were imploding a time
4053 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
4054 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
4055 uses those two fields to adjust the time value. Because of the HTTP
4056 spec, both of those values can be zero'ed out safely. This fixes
4057 the bug correctly. [Ryan Bloom]
4059 *) Fix a couple of place in the Windows code where the wrong error
4060 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
4062 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
4064 *) Added the APR_EOL_STR macro for platform dependent differences in
4065 logfiles and other raw text (such as all APR files). Fixes logfiles
4066 not terminated with cr/lf sequences in Win32. [William Rowe]
4068 *) Move all strings functions in APR to src/lib/apr/strings and create
4069 apr_strings.h for the prototypes. [Ryan Bloom]
4071 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
4072 to repeat the syscall until we stop getting EINTR. I noticed a
4073 related problem at termination (SIGTERM) on FreeBSD when using
4074 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
4075 implementation work properly with child init. Previously, ap_lock()
4076 was essentially a no-op because all children were using different
4077 locks and thus nobody ever blocked. [Jeff Trawick]
4079 *) The htdocs/ tree has been moved out of the CVS source tree into
4080 a separate area for easier development. This has NO EFFECT on
4081 end-users or Apache installations. [Ken Coar]
4083 *) Integrate the mod_dav module for WebDAV protocol handling. This
4084 adds the dav and dav_fs modules, the SDBM library, and additional
4085 XML handling utilities. [Greg Stein]
4087 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
4090 *) Update the lib/expat-lite/ library (bring forward changes from
4091 the Apache 1.3 repository). [Greg Stein]
4093 *) If sizeof(long long) == sizeof(long), then prefer long in APR
4094 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
4096 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
4097 machines where sendfile is detected, but nobody has written ap_sendfile.
4098 [Dave Hill <ddhill@zk3.dec.com>]
4100 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
4102 *) ab would start up more connections than needed, then quit when the
4103 desired number were finished. Also fixed a logic error involving
4104 ab keepalives. [Victor J. Orlikowski]
4106 *) WinNT: Implement non-blocking pipes with timeouts to communicate
4107 with CGIs. Apache 2.0a4 had non-blocking pipes but without
4108 timeouts (i.e, if a timeout was specified, the pipe reverted to
4109 a full blocking pipe). Now the behaviour is more in line with
4110 Unix non-blocking pipes.
4113 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
4114 cache open file handles along with accept socket reuse enables
4115 Apache 2.0 to serve non-keepalive requests for static files at
4116 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
4117 and Apache 2.0 will serve almost 1200 rps on my system).
4120 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
4121 supports two config directives, mmapfile (same behavious as
4122 mod_mmap_static) and cachefile. Use the cachefile directive
4123 to cache open file handles. This directive only works on systems
4124 that have implemented the ap_sendfile API. cachefile works today
4125 on Windows NT, but has not been tested on any flavors of Unix.
4128 *) Cleanup the configuration. With the last few changes the
4129 configuration process automatically:
4130 inherits information about how to build from APR. Allowing
4131 APR to inform Apache that it should or should not use -ldl
4133 Detects which mod_cgi should be used mod_cgi or mod_cgid,
4134 based on the threading model
4136 Apache calls APR's configure process before finishing it's
4137 configuration processing, allowing for more information flow
4142 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
4143 with non-zero argument makes the socket non-blocking. BeOS and
4144 OS/2 already worked this way. [Jeff Trawick]
4146 *) ap_close() now calls ap_flush() for buffered files, so write
4147 operations work a whole lot better on buffered files.
4150 *) Fix error messages issued from MPMs which explain where to change
4151 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
4154 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
4155 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
4156 now the way that the blocking state of a pipe is manipulated.
4157 ap_block_pipe() is gone. [Jeff Trawick]
4159 *) Correct the problem where the only local host name that the IP stack
4160 can discover are 'undotted' private names. If no fully qualified
4161 domain name can be identified, the default ServerName will be set to
4162 the machine's IP address string. A warning is always provided if the
4163 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
4165 *) Repair problems with config file processing which caused segfault
4166 at init when virtual hosts were defined and which caused ServerName to
4167 be ignored when there was no valid DNS setup. [Jeff Trawick]
4169 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
4171 *) Add ap_sendfile implementation for AIX
4172 [Victor J. Orlikowski]
4174 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
4175 apr_network_io.h, and apr_thread_proc.h.
4176 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
4178 *) Bring the allocation and pool debugging code back into a working
4179 state. This will need to be tested as so far it's only been used on
4182 *) Change configuration command setup to be properly typesafe when in
4183 maintainer mode. Note that this requires a compiler that can initialise
4184 unions. [Ben Laurie]
4186 *) Turn on buffering for config file reads. Part of this was to
4187 repair buffered I/O support in Unix and implement buffered
4188 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
4190 *) Win32: Fix problem where UTC offset was not being set correctly
4191 in the access log. Problem reported on news group by Jerry Baker.
4194 *) Fix segfault when reporting this type of syntax error:
4195 "</container> without matching <container> section", where
4196 container is VirtualHost or Directory or whatever.
4199 *) Prevent the source code for CGIs from being revealed when using
4200 mod_vhost_alias and the CGI directory is under the document root
4201 and a user makes a request like http://www.example.com//cgi-bin/cgi
4202 as reported in <news:960999105.344321@ernani.logica.co.uk>
4205 *) Add support for the new Beos NetwOrking Environment (BONE)
4208 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
4209 final input char is incomplete; ap_bwrite_xlate() now handles
4210 incomplete final input chars. [Jeff Trawick]
4212 *) Yet another update to saferead/halfduplex stuff -- need to ensure
4213 that a bhalfduplex call occurs before logging or else DNS and
4214 such can delay the last packet of the response. [Dean Gaudet]
4216 *) Some syscall reduction in APR on unix -- don't seek when setting
4217 up an mmap; and don't fcntl() more than once per socket.
4220 *) When mod_cgid is started as root, the cgi daemon now switches
4221 to the configured User/Group (like other httpd processes)
4222 instead of continuing as root. [Jeff Trawick]
4224 *) The prefork MPM now uses an APR lock for the accept() mutex.
4225 It has not been getting a lock at all recently. httpd -V now
4226 displays APR's selection of the lock mechanism instead of the
4227 symbols previously respected by prefork. [Jeff Trawick]
4229 *) Change the mmap() feature test to check only for existence.
4230 The previous check required features not used by Apache.
4233 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
4234 sometimes mangled. The len parm to accept() was not
4235 initialized, leading sometimes to an endless loop of failed
4236 accept() calls on OS/390 and anywhere else that failed the call
4237 if the len was negative. Use <sys/un.h> for struct sockaddr_un
4238 instead of declaring it ourselves to fix a compilation problem
4239 on Solaris. [Jeff Trawick]
4241 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
4243 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
4245 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
4247 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
4248 initialization if ALLOC_DEBUG is defined; no known symptom
4249 otherwise. [Jeff Trawick]
4251 *) Fix typo in configure script when checking for mod_so. bash
4252 doesn't seem to have a problem but /bin/sh on Solaris does.
4253 Symptom: "./configure: test: unknown operator =="
4256 *) Rebind the Win32 NT and 9x services control into the MPM.
4257 All console, WinNT SCM and Win9x pseudo-service control code is
4258 now wrapped within the WinNT MPM.
4261 *) Make a copy of getenv("PATH") before storing for later use. Some
4262 getenv() implementations use the same storage for successive calls.
4263 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
4265 *) Server Tokens work in 2.0 again. This also propogates the change
4266 to allow just the product name in the server string using
4270 Changes with Apache 2.0a4
4272 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
4273 won't need to call it. [Greg Ames, Jeff Trawick]
4275 *) Move pre_config hook call to between configuration read and config
4276 tree walk. This allows all modules to implement pre_config hooks
4277 and know that they will be called at an appropriate time.
4280 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
4283 *) Add pre-config hooks back to all modules.
4286 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
4287 ContentDigest enabled and we can't/don't mmap the file.
4290 *) We now report the correct line number for syntax errors in config
4291 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
4293 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
4294 related bugs, and changed shmem/locking to use apr API. Shared-mem
4295 is currently disabled, however, because of problems with graceful
4296 restarts. [Ronald Tschalär]
4298 *) Fix corruption of IFS variable in --with-module= handling.
4299 Depending on the user's shell or customization thereof, there
4300 would be errors generating ap_config_auto.h later in the configure
4301 procedure. [Jeff Trawick]
4303 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
4304 isn't used (as in 1.3), except that on Unix it is now logged via
4305 ap_log_rerror() instead of by the child having STDERR_FILENO refer
4306 to the error log. [Greg Ames, Jeff Trawick]
4308 *) Add '-D' argument processing for run time configuration defines.
4311 *) Organize http_main.c as independent code, such that no code or
4312 global data is exported from it. WIN32 will dynamically link it
4313 to the server core, so this will prevent mutual dependency.
4316 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
4317 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
4320 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
4321 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
4323 *) Add mod_charset_lite for configuring character set translation.
4326 *) Add '-n' option to htpasswd to make it print its user:pw record
4327 on stdout rather than having to frob a text file. [Ken Coar]
4329 *) Fix saferead. Basically, we flush the output buffer if a read on the
4333 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
4334 a conversion is single-byte only. [Jeff Trawick]
4336 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
4337 the BeOS 5.0 documentation says that shutdown doesn't work yet.
4340 *) Fix some minor errors where pid was being manipulated as an int
4341 instead of the portable pid_t. [Roy Fielding]
4343 *) Fix some error log prints that were printing the pointer to a
4344 structure rather than the pid within the structure.
4345 [Jeff Trawick, Roy Fielding]
4347 *) ab: Fix a command-line processing bug; track bad headers in
4348 err_response; support reading headers up to 2K.
4349 [Ask Bjoern Hansen <ask@valueclick.com>]
4351 *) Fix ap_resolve_env() so that it handles new function added in a prior
4352 alpha (see "Added the capability to do ${ENVVAR} constructs in the
4353 config file.") as well as the constructs used by mod_rewrite.
4354 [Paul Reder <rederpj@raleigh.ibm.com>]
4356 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
4358 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
4359 APR to perform translation, instead of accessing the hard-coded tables
4360 in 1.3's ebcdic.c. [Jeff Trawick]
4362 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
4365 *) Add the ability to hook into the config file reading phase. Basically
4366 if a directive is specified EXEC_ON_READ, then when that directive is
4367 read from the config file, the assocaited function is executed. This
4368 should only be used for those directives that must muck with HOW the
4369 server INTERPRETS the config. This should not be used for directives
4370 that re-order or replace items in the config tree. Those changes should
4371 be made in the pre-config step.
4374 *) Add mod_example to the build system.
4377 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
4378 byte character sets. [Jeff Trawick]
4380 *) Pick up various EBCDIC fixes from 1.3 (from Martin
4381 Kraemer and Oliver Reh originally according to the change log).
4384 *) Fix a couple of problems in RFC1413 support (controlled by the
4385 IdentityCheck directive). Apache did not build the request string
4386 properly and more importantly Apache would loop forever if the
4387 would-be ident server dropped the connection before sending a
4388 properly terminated response. [Jeff Trawick]
4390 *) apxs works in 2.0.
4393 *) Reliable piped logs work in 2.0.
4396 *) Introduce a hash table implementation into APR to be used for
4397 replacing tables and other random data structures in Apache.
4400 *) Add some more error reporting to htpasswd in the case of problems
4401 generating or accessing the temporary file. Also, pass in a
4402 buffer if the implementation knows how to use it (i.e., if L_tmpnam
4403 is defined). [Ken Coar]
4405 *) Configure creates config.nice now containing your configure
4406 options. Syntax: ./config.nice [--more-options]
4409 *) Fix various return code problems in APR on Win32. For most of
4410 these, APR was returning APR_EEXIST instead of GetLastError()/
4411 WSAGetLastError(). [Jeff Trawick]
4413 *) Make piped logs work again in version 2.0
4416 *) Add VPATH support to UNIX build system of Apache and APR.
4419 *) Fix ap_tokenize_to_argv to respect the const arguments that are
4423 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
4424 Patch submitted to author.
4427 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
4428 /sbin in PATH on FreeBSD (all submitted to rse previously)
4431 *) Fix building Pthread-based MPMs on OpenBSD
4432 [Sascha Schumann] PR#26
4434 *) Fix ap_readdir() problem on systems where d_name[] field in
4435 struct dirent is declared with only one byte. (This problem only
4436 affected multithreaded builds.) This caused a segfault during
4437 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
4438 least). [Jeff Trawick]
4440 *) Fix some make-portability problems on at least Tru64, Irix
4442 [Sascha Schumann] PR#18, PR#39
4444 *) Add ap_sigwait() to support old-style sigwait() on systems
4445 like OS/390 and UnixWare.
4448 *) Add POSIX-thread flags for more platforms.
4451 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
4452 (on Unix, at least) to handle resolver errors. Fix a bug in
4453 the definition of APR_ENOMEM so that ap_strerror() can spit
4454 out the correct error message for it.
4457 Changes with Apache 2.0a3
4459 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
4462 *) API: *HOOK* macros now have an AP_ prefix
4465 *) Win32: Eliminate redundant calls to initialize winsock.
4466 [Tim Costello <timcostello@ozemail.com.au>]
4468 *) Fix bugs initializing ungetchar for pipes.
4469 [Chia-liang Kao <clkao@CirX.ORG>]
4471 *) The ab program in the src/support directory is now portable using
4475 *) Support directory is being compiled when the server is built
4478 *) The configure option --with-program-name has been added to allow
4479 developers to rename the executable at configure time. This also
4480 changes the name of the config files to match the executable's name.
4483 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
4484 containing version numbers. [Martin Pool]
4486 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
4487 Unix; access_log and error_log now created with these perms; non-
4488 Unix is unaffected [Jeff Trawick]
4490 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
4491 Replaced more magic numbers with MD5_DIGESTSIZE.
4492 [William Rowe, Roy Fielding]
4494 *) Win32: Get mod_auth_digest compiling and added to the Windows
4495 build environment. Not tested and I'd be suprised if it
4496 actually works. [Bill Stoddard]
4498 *) Revamp the Win32 make environment. Makefiles have been removed and
4499 Apache.dsw created to bring together all the pieces. Create new file
4500 os/win32/BaseAddr.ref to define module base addresses (to prevent
4501 dll relocation at start-up).
4502 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
4504 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
4505 of the \015, \012, and \015\012 constants with macros.
4508 *) Add ap_xlate_open() et al for translation of text between different
4509 character sets. The initial implementation requires iconv().
4512 *) More FAQs and answers from comp.infosystems.www.servers.unix.
4513 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4515 *) CGI output is being timed out now.
4518 *) Fix the problem with dieing quietly. dupfile now takes a pool which
4519 is used by the new apr file. There is no reason to create a new file
4520 with the same lifetime as the original file.
4523 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
4524 module base addresses. This will help shooting seg faults
4525 in the field. [William Rowe <wrowe@lnd.com>]
4527 *) Update Apache on Windows documentation. Add new document
4528 describing how to compile Apache on Windows.
4529 [William Rowe <wrowe@lnd.com>]
4531 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
4532 microseconds instead of seconds. Some storage leaks and other
4533 minor bugs in related code were fixed. [Jeff Trawick]
4535 *) Win32: First cut at getting mod_isapi working under 2.0
4536 [William Rowe <wrowe@lnd.com>]
4538 *) First stab at getting mod_auth_digest working under 2.0
4539 quick change summary:
4540 - moved the random byte generation (ap_generate_random_bytes) into APR
4541 - now uses ap_time_t
4542 - compiles and runs on linux
4544 [Brian Martin <bmartin@penguincomputing.com>]
4546 *) Win32: Move the space stripping of physical service names
4547 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
4548 unresolved symbol. Add dependency checking to the
4549 CreateService call to ensure TCPIP and AFP (winsock) is started
4551 [William Rowe <wrowe@lnd.com>]
4553 *) Win32: Add code to perform latebinding on functions that may
4554 not exist on all levels of Windows where Apache runs. This
4555 is needed to allow Apache to start-up on Win95/98. All calls
4556 to non portable functions should be protected with
4557 ap_oslevel checks to prevent runtime segfaults.
4558 [William Rowe <wrowe@lnd.com>]
4560 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
4562 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
4564 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
4565 This addresses PR 1623. Still need to address timing out runaway
4566 CGI scripts. [Bill Stoddard]
4568 *) Win32: Make ap_stat Windows 95/98 friendly
4569 [William Rowe <wrowe@lnd.com>]
4571 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
4572 always fail. Need to initialise the dwOSVersionInfoSize member of the
4573 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
4576 The patch also enhances ap_get_oslevel (and the associated enum) to
4577 handle selected service packs for NT4, and adds recognition for
4578 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
4579 we can use ReadFileScatter and WriteFileGather in readwrite.c.
4580 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
4582 *) Get mod_rewrite building and running, and mod_status building for Win NT
4583 [Allan Edwards <ake@raleigh.ibm.com>]
4585 *) Patch to port mod_auth_db to the 2.0 api and also to support
4586 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
4587 2.7.7. It should work with version 1 as well but I haven't tested it.
4588 [Brian Martin <bmartin@penguincomputing.com>]
4590 *) Get APR DSO code working under Windows. Includes cross platform
4592 [Tim.Costello@BTFinancialgroup.com]
4594 *) Fix some of the Windows APR time functions.
4597 *) FAQ changes related to tidying up historical documents on the web site.
4598 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4600 *) Move Windows DSO code into APR.
4603 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
4604 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
4605 at build time. At this point, the server will not compile on Windows because
4606 of the recent DSO commits. Fixing those next.
4607 [Bill Rowe & Bill Stoddard]
4609 *) Added error checking for file I/O APR routines.
4610 [Jon Travis <jtravis@covalent.net>]
4612 *) APR: Don't use the values of resolver error codes for the
4613 corresponding APR error codes. On Unix and Win32, return the
4614 proper APR error code after a resolver error. [Jeff Trawick]
4616 Changes with Apache 2.0a2
4618 *) Renamed the executable back to httpd on all platforms other
4622 *) Allow BeOS to survive restarts, log properly and a few
4623 small things it had problems with due to the way it setup
4624 users and groups. [David Reid]
4626 *) Get mod_rewrite working with APR locks
4627 [Paul Reder <rederpj@raleigh.ibm.com>]
4629 *) Actually remove the sempahore when the lock cleanup routine
4630 is called on BeOS. [David Reid]
4632 *) Clear hook registrations between reads of the config file.
4633 When DSOs are unloaded and re-loaded the old hook pointers may
4634 no longer be valid. This fix eliminates potential segfaults.
4635 [Allan Edwards <ake@raleigh.ibm.com>]
4637 *) Fix a problem with Sigfunc not being defined or bypassed
4638 if sigaction() wasn't found. [Jim Jagielski]
4640 *) Fix the locking mechanism on BSD variants. They now use fcntl
4641 locks. This allows the server to start and serve pages.
4644 *) First cut at getting the Win32 installer to work
4645 [William Rowe <wrowe@lnd.com>]
4647 *) Get htpasswd compiling under Windows
4648 [William Rowe <wrowe@lnd.com>]
4650 *) Change the log message for a bind() failure to show the
4651 interface and port number. [Jeff Trawick]
4653 *) Import the documentation from 1.3.12 and bring parts of it
4654 up-to-date with respect to the changes that have occurred
4658 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
4659 now logged correctly on BeOS.
4662 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
4663 Makefile.win includes the same user interface as the old
4665 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
4667 *) Win32 exec now uses COMSPEC environment string for command
4668 shell path resolution.
4669 [William Rowe <wrowe@lnd.com>] PR#3715
4671 *) Win32: ap_connect() was not returning correct error condition
4673 [Allen Prescott <allen@clanprescott.com>]
4675 *) Win32: ap_open() was broken on Win9x because an NT-specific
4676 flag was passed to CreateFile. ap_puts() added an unnecessary
4678 [Jeff Trawick <trawick@us.ibm.com>]
4680 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
4681 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
4682 confusing ee/et name and made all extensions language/dialect
4683 rather than country reflecting. Changed example files to
4684 explicit reflect the ISO charset and added a few common
4685 ones to the example config [dirkx]
4687 *) Extend external module capability. To use this, you call
4688 configure with --with-module=path/to/mod1,path/to/mod2,etc.
4691 *) Backported the various "default charset" fixes from 1.3.12,
4692 including the AddDefaultCharset directive. [Jim Jagielski]
4694 *) Added the capability to do ${ENVVAR} constructs in the
4695 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
4696 it does this on a line by line basis; i.e. if the envvar
4697 expands to something with spaces you have to protect it
4698 by adding quotes around it (Unless of course you expect it
4699 to contains more than one argument. Alternatively you
4700 can compile it on a per token basis; which is what people
4701 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
4702 hampers fancier hacks.
4703 [Dirk-Willem van Gulik]
4705 *) Changed the 'ErrorDocument' syntax in that it NO longer
4706 supports the asymetric
4708 ErrorDocument 301 "Some message
4710 Note the opening " quote, without a closing quote. It now
4711 has either the following syntaxes
4713 ErrorDocument XXX /local/uri
4714 ErrorDocument XXX http://valid/url
4715 ErrorDocument XXX "Some Message"
4717 The recognition heuristic is: if it has a space it
4718 is a message. If it has no spaces and starts with a /
4719 or is a valid URL then treat it that way. Otherwise it
4720 is assumed to be a message.
4722 This breaks backward compatibility but makes live a hell
4723 of a lot easier for GUI's and config file parsers.
4724 [Dirk-Willem van Gulik]
4726 *) Changed 'CacheNegotiatedDocs' from its present/not-present
4727 syntax into a 'on' or 'off' syntax. As it currently is the
4728 only non nesting token which uses NO_ARGS and thus is an
4729 absolute pain for any config interface automation. This
4730 breaks backward compatibility. [Dirk-Willem van Gulik]
4732 *) Add ability to add external modules to the build process. This is
4733 done with --with-module=/path/to/module. Modules can only be added
4734 as static modules at this point.
4737 Changes with Apache 2.0a1
4739 *) Fix FreeBSD 3.3 core dump.
4740 Basically, ap_initialize() needs to get called before
4741 create_process(), since create_process() passes op_on structure
4742 to semop() to get a lock, but op_on isn't initialized until
4743 ap_initialize() calls setup_lock(). Here is a slight
4744 rearrangement to main() which calls ap_initialize() earlier...
4745 [Jeff Trawick <trawick@us.ibm.com>]
4747 *) Enable Apache to use sendfile/TransmitFile API
4748 [Bill Stoddard, David Reid, Paul Reder]
4750 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
4754 *) Make file I/O and network I/O writev/sendv APIs consistent.
4755 Eliminate use of ap_iovec_t and use Posix struct iovec.
4756 Use seperate variable on ap_writev to set the number of iovecs
4757 passed in and number of bytes written.
4760 *) Adapt file iol to use APR functions. Replaced ap_open_file()
4761 with ap_create_file_iol(). ap_create_file_iol() requires that
4762 the file be opened prior to the call using ap_open().
4765 *) Port mod_include and mod_cgi to 2.0
4766 [Paul Reder, Bill Stoddard]
4768 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
4769 bytes_read/bytes_written is always valid (never -1). Plus
4770 some fixes to buff.c to correct problems introduced by the
4771 errno => ap_status_t changes a while back. Plus a fix to
4772 chunked encoding introduced right at the beginning of 2.0.
4775 *) Revamped UNIX build system to use autoconf and libtool.
4776 [Manoj Kasichainula, Sascha Schumann]
4778 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
4780 *) More rigorous checking of Host: headers to fix security problems
4781 with mass name-based virtual hosting (whether using mod_rewrite
4782 or mod_vhost_alias).
4783 [Ben Hyde, Tony Finch]
4785 *) Add back support for UseCanonicalName in <Directory> containers.
4786 [Manoj Kasichainula]
4788 *) Added APLOG_STARTUP log type. This allows us to write an error
4789 message without any of the date and time information. As a part
4790 of this change, I also removed all of the calls to fprintf(stderr
4791 and replaced them with calls to ap_log_error using APLOG_STARTUP
4792 writing to stderr is no longer portable, because we don't direct
4793 stderr to the error log on all platforms.
4796 *) Convert error logging functions to take errno as an argument.
4797 This makes our error logs more portable, because some Windows API's
4798 don't set errno. This change allows us to still output a valid
4799 message on all of our platforms.
4802 *) mod_mime_magic runs in 2.0-dev now.
4803 [Paul Reder <rederpj@raleigh.ibm.com>]
4805 *) sendfile has been added to APR.
4806 [John Zedlewski <zedlwski@Princeton.EDU>]
4808 *) buff.c has been converted to no longer use errno.
4809 [Manoj Kasichainula]
4811 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
4812 interface adaption to APR functions did it. [Martin Kraemer]
4814 *) Support DSOs properly on 32-bit HP-UX 11.0
4815 [Dilip Khandekar <dilip@cup.hp.com>]
4817 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
4818 [Ralf S. Engelschall]
4820 *) Cleaned APR build environment integration and bootstrap APR
4821 automatically for developers from src/Configure.
4822 [Ralf S. Engelschall]
4824 *) Fixed building of src/support/htpasswd.c
4825 [Ralf S. Engelschall]
4827 *) When generating the Location: header, mod_speling forgot
4828 to escape the spelling-fixed uri. (Forw-Port from 1.3)
4831 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
4833 *) Change all pools to APR contexts. This is the first step to
4834 incorporating APR into Apache. [Ryan Bloom]
4836 *) Move "handler not found" warning message to below the check
4837 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
4838 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
4840 *) Support line-continuation feature in config.option file and
4841 allow the loading of multiple option sections at once via
4842 ``--with-option=<section1>,<section2>,...''
4843 [Ralf S. Engelschall]
4845 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
4847 Changes with Apache MPM
4849 *) Use asynchronous AcceptEx() and a completion port to accept and
4850 dispatch connections to threads in Windows NT/2000.
4853 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
4856 *) Implement the APACI --with-option facility
4857 (per default used the config.option file).
4858 [Ralf S. Engelschall]
4860 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
4862 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
4863 Replace pre_connection module call with a register_hook call and
4864 implement pre_connection as a hook. The intent is that these hooks will
4865 be extended to allow Apache to be multi-protocol, and also to allow the
4866 calling order to be specified on a per-hook/per-module basis.
4869 *) Implement mpm_* methods as "modules". Each method gets its own
4870 subdir in src/modules (eg: src/modules/prefork). Selection
4871 of method uses Rule MPM_METHOD. [Jim Jagielski]
4873 *) Port the hybrid server from the apache-apr repository as
4874 mpm_mpmt_pthread. [Manoj Kasichainula]
4876 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
4877 amongst the unix MPMs.
4879 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
4880 signal handling for the new world order. [Dean Gaudet]
4882 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
4883 of alloc.c for now. [Dean Gaudet]
4885 *) Handle partial large writes correctly. [Ben Laurie]
4887 *) Eliminate conn_rec's pointer to server. All it knows is the base server
4888 based on IP/port. [Ben Laurie]
4890 *) Port a bunch of modules to the new module structure.
4891 ["Michael H. Voase" <mvoase@midcoast.com.au>]
4893 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
4895 *) Basic restructuring to introduce the MPM concept; includes various
4896 changes to the module API... better described by
4897 docs/initial_blurb.txt. [Dean Gaudet]
4899 Changes with Apache pthreads
4901 *) New buff option added: BO_TIMEOUT. It describes the timeout for
4902 buff operations (generally over a network).
4903 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
4905 *) Created http_accept abstraction. Added 4 new functions (not exported):
4906 init_accept(), begin_accepting_requests(), get_request(),
4907 stop_accepting_requests() [Bill Stoddard]
4909 *) Fix to ap_rprintf call that allows mod_info to work properly.
4910 [James Morris <jmorris@intercode.com.au>]
4912 *) user and ap_auth_type fields were moved from connection_rec to
4913 request_rec. [Ryan Bloom]
4915 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
4916 needed in a threaded server.
4918 *) Initial pthread implementation from from Dean's apache-nspr code.
4919 [Bill Stoddard, Ryan Bloom]
4922 Changes with Apache 1.3.9
4924 *) Remove bogus error message when a redirect doesn't set Location.
4925 Instead, use an empty string to avoid coredump if the error message
4926 was supposed to include a location. [Roy Fielding]
4928 *) Don't allow configure to include mod_auth_digest unless it is
4929 explicitly requested, even if the user asked for all modules.
4932 *) Translate module names to dll names for OS/2 so that they are no more
4933 than 8 characters long and have an extension of "dll" instead of "so".
4936 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
4937 Fix test-compile check to check for randbyte instead of trand32.
4938 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
4939 and tweak to make Amaya happier. [Ronald Tschalär]
4941 *) Ensure that the installed expat include files are world readable,
4942 just like the other header files. [Martin Kraemer]
4944 *) Fixed generated AddModule adjustments in APACI's `configure' script
4945 in order to allow (new) modules like mod_vhost_alias to be handled
4946 correctly (which was touched by the adjustments for mod_alias).
4947 [Ralf S. Engelschall]
4949 *) For binary builds, add -R flag to apachectl to work around the lack of
4950 an absolute path to the ./libexec directory where the libhttp.ep file
4951 is needed for SHARED_CORE architectures. [Randy Terbush]
4953 *) WIN32: Create the CGI script process as DETACHED. This may solve the
4954 problem observed by some Win95/98 users where they get CGI script
4955 output sent to the console. [Bill Stoddard]
4957 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
4958 routines are now called ap_base64* and are 'plain' (i.e., no
4959 pool access or anything clever). Inside util.c the routines acting
4960 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
4961 The oddly named ap_uuencode(), ap_uudecode() are kept around for
4962 now but deprecated. [dirkx]
4964 *) Clean up the base64 and SHA1 additions and make sure they are
4965 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
4966 files. [Roy Fielding]
4968 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
4969 checking. Allow compiling on VS 6.0. [Randy Terbush]
4971 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
4973 *) Use TestCompile to search for the truerand library (rather than blindly
4974 assuming its existence). If it is not found, complain (but do not
4975 exit - yet). [Martin Kraemer]
4977 *) We forgot to add the new exported function names to
4978 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
4980 *) Add description of -T command-line option to usage().
4981 [Ralf S. Engelschall]
4983 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
4984 searched only AFTER libap has been searched, because libap needs
4985 some symbols from libos. [Martin Kraemer]
4987 *) Fix conflict with original mod_digest related to the symbol of the
4988 module dispatch list (which has to be unique for DSO and follow the
4989 usual conventions for the installation procedure).
4990 [Ralf S. Engelschall]
4992 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
4993 for other platforms as well. [Martin Kraemer]
4995 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
4996 types by AP_LONG and replace reference to renamed variable 'ubuf'
4997 by 'buffer'. [Martin Kraemer]
4999 Changes with Apache 1.3.8 [not released]
5001 *) Flush the output buffer immediately after sending an error or redirect
5002 response, since the result may be needed by the client to abort a
5003 long data transfer or restart a series of pipelined requests.
5004 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
5006 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
5007 [Ian Turner <iant@sequent.com>] PR#4735
5009 *) Local struct mmap in http_core.c conflicted with system structure
5010 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
5012 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
5013 [Ronald Tschalär <ronald@innovation.ch>]
5015 *) Fix a memory leak where the module counts were getting messed
5016 up across restarts. [David Harris <dharris@drh.net>]
5018 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
5019 properly in mod_access.
5020 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
5022 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
5023 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
5025 *) PORT: Support for compaq/tandem/com.
5026 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
5028 *) Added SHA1 password encryption support to easy migration from
5029 Netscape servers. See support/SHA1 for more information.
5030 Caused the separation of ap_md5.c into md5, sha1 and a general
5031 ap_checkpass.c with just a validate_passwd routine. Added a
5032 couple of flags to support/htpasswd. Some reuse of the to64()
5033 function; hence renamed to ap_to64().
5034 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
5036 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
5037 with ASCII/EBCDIC conversions in "ident" query.
5038 [David McCreedy <McCreedy@us.ibm.com>]
5040 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
5041 Change "Power Macintosh" to Power* so if uname prints "Power Book"
5042 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
5044 *) Fix SIGSEGV on some systems because the Vary fix below included
5045 a call to table_do with a variable argument list that was not
5046 NULL terminated. Replaced with better implementation. [Roy Fielding]
5048 Changes with Apache 1.3.7 [not released]
5050 *) The "Vary" response header field is now sanitised right before
5051 the header is sent back to the client. Multiple "Vary" fields
5052 are combined, and duplicate tokens (e.g., "Vary: host, host" or
5053 "Vary: host, negotiate, host, accept-language") are reduced to
5054 single instances. This is a better solution than the force-no-vary
5055 one (which is still valid for clients that can't cope with Vary
5056 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
5058 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
5060 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
5061 least on Linux and FreeBSD for now.
5064 *) Win32: More apache -k restart work. Restarts are now honored
5065 immediately and connections in the listen queue are -not- lost.
5066 This is made possible by the use of the WSADuplicateSocket()
5067 call. The listeners are opened in the parent, duplicated, then
5068 the duplicates are passed to the child. The original listen sockets
5069 are not closed by the parent across a restart, thus the listen queue
5071 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5073 *) Fix handling of case when a client has sent "Expect: 100-continue"
5074 and we are going to respond with an error, but get stuck waiting to
5075 discard the body in the pointless hope of preserving the connection.
5076 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
5078 *) Fix 'configure' to work correctly with SysV-based versions of
5079 'tr' (consistent with Configure's use as well). [Jim Jagielski]
5081 *) apxs: Add "-S var=val" option which allows for override of CFG_*
5082 built-in values. Add "-e" option which works like -i but doesn't
5083 install the DSO; useful for editing httpd.conf with apxs. Fix
5084 editing code so that multiple invocations of apxs -a will not
5085 create duplicate LoadModule/AddModule entries; apxs can now be
5086 used to re- enable/disable a module. [Wilfredo Sanchez]
5088 *) Win32: Update the server to use Winsock 2. Specifically, link with
5089 ws2_32.lib rather than wsock32.lib. This gives us access to
5090 WSADuplcateSocket() in addition to some other enhanced comm APIs.
5091 Win 95 users may need to update their TCP/IP stack to pick up
5092 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
5093 [Bill Stoddard stoddard@raleigh.ibm.com]
5095 *) Win32: Redirect CGI script stderr (script debug info) into the
5096 error.log when CGI scripts fail. This makes Apache on Win32
5097 behave more like Unix.
5098 [Bill Stoddard stoddard@raleigh.ibm.com]
5100 *) Fixed `httpd' usage display: -D was missing.
5101 [Ralf S. Engelschall] PR#4614
5103 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
5104 [Ralf S. Engelschall] PR#4561, PR#4562
5106 *) OS/2: Fix problem with accept lock semaphores where server would die with
5107 "OS2SEM: Error 105 getting accept lock. Exiting!"
5108 [Brian Havard] PR#4505
5110 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
5111 [Randy Terbush <randy@covalent.net>]
5113 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
5114 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
5116 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
5117 command potentially _is_ GCC. [Ralf S. Engelschall]
5119 *) Fix apxs build issues on AIX
5120 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
5122 *) DocumentRoot Checking: Under previous versions, when Apache
5123 first started up, it used to do a stat of each DocumentRoot to
5124 see if it existed and was a directory. If not, then an error
5125 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
5126 does not exist, you will get error messages in error_log. If
5127 the '-t' command line option is used (to check the configuration)
5128 the check of DocumentRoot IS performed. An additional command
5129 line option, '-T', has been added if you want to avoid the
5130 DocumentRoot check even when checking the configuration.
5133 *) Win32: The query switch "apache -S" didn't exit after showing the
5134 vhost settings. That was inconsistent with the other query functions.
5135 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
5137 *) Win32: Changed behaviour of apache -k restart.
5138 Previously, the server would drain all connections in the stack's

5174 *) TestCompile updated. We can now run programs and output the
5175 results during the Configure process. [ Jim Jagielski]
5177 *) The source is now quad (long long) aware as needed. Specifically,
5178 the Configure process determines the correct size of off_t and
5179 *void. When the OS/platform/compiler supports quads, ap_snprintf()
5180 provides for the 'q' format qualifier (if quads are not available,
5181 'q' is silently "demoted" to long). [Jim Jagielski]

5459 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
5460 a roughly 5 fold speed up. [Brian Havard]
5462 *) proxy ftp: instead of using the hardwired string "text/plain" as
5463 a fallback type for files served by the ftp proxy, use the
5464 ap_default_type() function to determine the configured type.
5465 This allows for special configurations like
5466 <Directory proxy:ftp://some.host>
5467 DefaultType gargle/blurb
5469 Additionally, add the Content-Encoding: header to FTP proxy replies
5470 when the encoding is defined (by the AddEncoding directive).
5471 Because it was missing, it was almost impossible to browse compressed
5472 files using the FTP proxy (works now perfectly in Communicator).
5473 The ftp proxy now also returns the Date: and Server: header lines (if not
5474 much else... This code is "somewhat" broken) like normal requests do.

5523 work correctly on EBCDIC platforms.

5594 *) In configure, do not append the target name to the directory path if
5595 the path already contains "apache". [Ralf S. Engelschall]
5597 *) SIGPIPE is now ignored by the server core. The request write routines
5598 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
5599 correctly check for output errors and mark the connection as aborted.
5600 Replaced many direct (unchecked) calls to ap_b* routines with the
5601 analogous ap_r* calls. [Roy Fielding]
5603 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
5604 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
5605 Furthermore map lookups for non-existent keys are now cached as well.
5606 Additionally "txt" maps are now parsed with simple string functions
5607 instead of using ap_pregcomp(). As a side effect a bug that prevented
5608 the usage of keys containing the "," character was fixed.
5609 The changes drastically improve the performance when large rewrite maps

5660 reason of a failure to a client rather than the "internal
5661 server error" it does currently. The general exposure mechanism
5662 can be triggered by any module by setting the "verbose-error-to"
5663 note to "*"; this allows more than just proxy errors to be exposed.
5664 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
5666 *) Moved man pages for ab and apachectrl to section 8.
5667 [Wilfredo Sanchez, Roy Fielding]
5669 *) Added -S option to install.sh so that options can be passed to
5670 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
5672 *) Tweak modules Makefile generated by Configure so that it handles
5673 the test case of no modules being selected. [chaz@reliant.com]
5675 *) Added a <LimitExcept method ...> sectioning directive that allows
5676 the user to assign authentication control to any HTTP method that
5677 is *not* given in the argument list; i.e., the logical negation
5678 of the <Limit> directive. This is particularly useful for controlling
5679 access on methods unknown to the Apache core, but perhaps known by
5680 some module or CGI script. [Roy Fielding, Tony Finch]
5682 *) Prevent apachectl from complaining if the PIDFILE exists but
5683 does not contain a process id, as might occur if the server is
5684 being rapidly restarted. [Wilfredo Sanchez]
5686 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
5688 *) Entity tag comparisons for If-Match and If-None-Match were not being
5689 performed correctly -- weak tags might cause false positives. Also,
5690 strong comparison wasn't properly enforced in all cases.
5691 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
5693 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
5696 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
5697 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
5699 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
5700 to util.c for parsing an HTTP header field value to extract the next
5701 list item, taking into account the possible presence of nested comments,
5702 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
5703 insignificant whitespace and lowercases non-quoted tokens.
5704 [Roy Fielding] PR#2065
5706 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
5707 code different from 500. This allows the proxy to, e.g., return
5708 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
5710 *) Fix ordering of language variants for the case where the traditional
5711 negotiation algorithm is being used with multiple language variants
5712 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
5714 *) Do not round the TCN quality calculation to 5 decimal places,
5715 unlike RFC 2296, because the calculation might need 12 decimal places
5716 to get the right result. [Roy Fielding]
5718 *) Remove unused code to disable transparent negotiation when
5719 negotiating on encoding only, as we now handle encoding too
5720 (though this is nonstandard for TCN), remove charset=ISO-8859-1
5721 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
5722 some debugging statements within mod_negotiation. [Koen Holtman]
5724 *) Fixed a rare memory corruption possibility in mod_dir if the index
5725 file is negotiable and no acceptable variant can be found.
5726 [Dean Gaudet, Roy Fielding, Martin Kraemer]
5728 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
5729 searching the Win32 registry for script interpreters.
5732 *) Win32: The compiled-in default filename for the error log is now
5733 error.log, which matches the default in the distributed httpd.conf.
5736 *) Win32: Any error messages from -i or -u command line options are now
5737 displayed on the console output rather than sent to the error log.
5738 Also the "Running Apache..." message is not output unless Apache is
5739 going to serve requests. [Paul Sutton]
5741 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
5742 and use a private significator ('$apr1$') to mark passwords as
5743 being smashed with our own algorithm. Also abstract the password
5744 checking into a new ap_validate_password() routine. [Ken Coar]
5746 *) Win32: The filename validity checker now allows "COM" but refuses
5747 access to "COM1" through "COM4". This allows filenames such
5748 as "com.name" to be served. [Paul Sutton] PR#3769.
5750 *) BS2000: Adapt to the new ufork() system call interface which will
5751 make subtasking easier on the OSD/POSIX mainframe environment.
5754 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
5755 ap_compat.h. [David White <david@persimmon.com>] PR#3725
5757 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
5758 use `.db' instead of `.pag' not only for FreeBSD, but also when
5759 the NDBM library looks like Berkeley-DB based.
5760 [Ralf S. Engelschall] PR#3773
5762 *) Add ability to handle DES or MD5 authentication passwords.
5763 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
5765 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
5767 *) SECURITY: Avoid some buffer overflow problems when escaping
5768 quoted strings. (This overflow was on the heap and we believe
5769 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
5771 *) Let src/Configure be aware of CFLAGS options starting with plus
5772 signs as it's the case for the HP/UX compiler.
5773 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
5775 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
5776 and check to see if the tar we wind up with supports '-h'.
5777 [Jim Jagielski] PR#3671
5779 *) A consistent and conservative style for all shell scripts has been
5780 implemented. Basically, all shell string tests use the traditional
5781 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
5782 to protect against bare null variable strings (ie: wrapping both
5783 sides with double quotes and prepending 'x'). 'x' was chosen
5784 because it's more universal and hopefully easier for old shell
5785 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
5788 *) The status module now prints out both the main server generation as
5789 well as the generation of each process. Also, the vhost info is
5790 printed with '?notable'. [Jim Jagielski]
5792 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
5793 and this makes its functions available to things in src/support.
5796 Changes with Apache 1.3.4
5798 *) Renamed macros status_drops_connection to ap_status_drops_connection
5799 and vestigial scan_script_header to ap_scan_script_header_err,
5800 mostly for aesthetic reasons. [Roy Fielding]
5802 *) The query switch "httpd -S" didn't exit after showing the
5803 vhost settings. That was inconsistent with the other query functions.
5806 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
5807 filename to the end of the STANDARD_MODULE_STUFF. Its
5808 presence at the beginning prevented reporting of the filename
5809 for modules compiled before 1 January 1999. [Ken Coar]
5811 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
5812 to detect and prevent access to special DOS device file names.
5813 [Paul Sutton, Ken Parzygnat]
5815 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
5816 and Makefile_win32_debug.txt (debug build) that work on Win95.
5817 Run each of the following from the src directory:
5818 nmake /f Makefile_win32.txt # compiles normal build
5819 nmake /f Makefile_win32.txt install # compiles and installs
5820 nmake /f Makefile_win32.txt clean # removes compiled junk
5821 nmake /f Makefile_win32_debug.txt # compiles debug build
5822 nmake /f Makefile_win32_debug.txt install
5823 nmake /f Makefile_win32_debug.txt clean
5826 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
5827 to build binary distributions. [Lars Eilebrecht]
5829 *) IndexOptions SuppressColumnSorting only turned off making
5830 the column headers anchors; you could still change the display
5831 order by manually adding a '?N=A' or similar query string to the
5832 URL. Now SuppressColumnSorting locks in the sort order so
5833 it can't be overridden this way. [Ken Coar]
5835 *) Added IndexOrderDefault directive to supply a default sort order
5836 for FancyIndexed directory listings. [Ken Coar] PR#1699
5838 *) Change the ap_assert macro to a variant that works on all platforms.
5839 [Richard Prinz <richard.prinz@cso.net>] PR#2575
5841 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
5842 search for an underscore on dlsym() (as it's already the case
5843 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
5845 *) Small fix for mod_env.html: The module was documented as to be _not_
5846 compiled into Apache per default, although it _IS_ compiled into
5847 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
5849 *) Instead of fixing a bug in the generation procedure for config.status (a
5850 backslash was missing) we remove the bug together with it's complete
5851 context because the special cases of the past can now no longer occur
5852 because of the recent magic for the --with-layout default.
5853 [Ralf S. Engelschall] PR#3590
5855 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
5856 making sure the src/support/ tools are _forced_ to be build last (they
5857 depend on other libraries).
5858 [Markus Theissinger <markus.theissinger@gmx.de>]
5860 *) Fix installation procedure: Now that os-inline.c is actually used (a
5861 recently fixed bug prevented this) we need to also install os-include.c
5862 in addition to os.h into the PREFIX/include/ location or building of
5863 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
5865 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
5866 allow us to distinguish between a garbled DSO (or even a file which isn't
5867 an Apache module DSO at all) and a DSO which doesn't match the current
5868 Apache API. [Ralf S. Engelschall] PR#3152
5870 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
5871 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
5872 match case insensitive (this especially avoids nasty patterns like
5873 `[tT][eE][sS][tT]'). Second two additional internal map functions
5874 `escape' and `unescape' were added which can be used to escape/unescape
5875 to/from hex-encodings in URLs parts (this is especially useful in
5876 combination with map lookups).
5877 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
5879 *) Renamed the macro escape_uri() to ap_escape_uri() which was
5880 forgotten (because it was a macro) in the symbol renaming process.
5881 [Ralf S. Engelschall]
5883 *) Fix some inconsistencies related to the scopes of directives. The only
5884 user visible change is that the directives `UseCanonicalName' and
5885 `ContentDigest' now use the (more correct) `Options' scope instead of
5886 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
5888 *) Using DSO, the Server token was being mangled. Specifically, the
5889 module's token was being added first before the Apache token. This
5890 has been fixed. [Jim Jagielski]
5892 *) Major overhaul of mod_negotiation.c, part 2.
5893 - properly handle "identity" within Accept-Encoding.
5894 - allow encoded variants in RVSA negotiation and let them appear in
5895 the Alternates field using the non-standard "encoding" tag-list.
5896 - fixed both negotiation algorithms so that an explicitly accepted
5897 encoding is preferred over no encoding if "identity" is not
5898 included within Accept-Encoding.
5899 - added ap_array_pstrcat() to alloc.c for efficient concatenation
5900 of large substring sequences.
5901 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
5904 *) Major overhaul of mod_negotiation.c, part 1.
5905 - cleanups to mod_negotiation comments and code structure
5906 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
5907 support for everything in the upcoming HTTP/1.1
5908 revision (draft-ietf-http-v11-spec-rev-06.txt).
5909 - language tag matching also handles tags with more than 2
5911 - empty Accept, Accept-Language, Accept-Charset headers are
5912 processed correctly; previously an empty header would make all
5913 values acceptable instead of unacceptable.
5914 - allowed for q values in Accept-Encoding
5915 - added support for transparent content negotiation (rfc2295 and
5916 rfc2296) (though we do not implement all features in these drafts,
5917 e.g. no feature negotiation). Removed old experimental version.
5918 - implemented 'structured entity tags' for better cache correctness
5919 (structured entity tags ensure that caches which can deal with Vary
5920 will (eventually) be updated if the set of variants on the server
5922 - this involved adding a vlist_validator element to request_rec
5923 - this involved adding the ap_make_etag() function to the global API
5924 - modified guessing of charsets used by Apache negotiation algorithm
5925 to guess 'no charset' if the variant is not a text/* type
5926 - added code to sort multiviews variants into a canonical order so that
5927 negotiation results are consistent across backup/restores and mirrors
5928 - removed possibility of a type map file resolving to another type map
5929 file as its best variant
5930 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
5932 *) RFC2396 allows the syntax http://host:/path (with no port number)
5933 but the proxy disallowed it (ap_proxy_canon_netloc()).
5934 [David Kristol <dmk@bell-labs.com>] PR#3530
5936 *) When modules update/modify the file name in the configfile_t structure,
5937 syntax errors will report the updated name, not the original one.
5938 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
5940 *) Correct some filename case assumptions from WIN32 to
5941 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
5943 *) For %v log ServerName regardless of the UseCanonicalName
5944 setting (similarly for %p). [Dean Gaudet]
5946 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
5947 rather late (too late for some invocations of TestCompile).
5948 This improves the make environment available to TestCompile and
5949 the *.module scripts. [Martin Kraemer]
5951 *) The hashbang emulation code in ap_execve.c would interpret
5952 #!/hashbang/scripts correctly, but failed to fall back to a
5953 standard shell for scripts which did NOT start with #!
5954 Now SHELL_PATH is started in these cases. [Martin Kraemer]
5956 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
5959 *) Update APXS manual page: some -q option arguments were missing
5960 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
5962 *) Cleanup the command line options: `-?' was documented to show
5963 the usage list but does it with an error because `?' is not a valid
5964 command. OTOH a lot of users expect `-h' to print such a usage list and
5965 instead are annoyed for ages by our huge unreadable list of directives.
5966 So we now changed the command line options this way:
5968 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
5969 very similar to the popular linker option.
5971 Intent: while -l gives the small list of modules, -L now gives the
5972 large list of directives implemented by these modules. This is also
5973 consistent with -v (short version info) and -V (large version info).
5975 Intent: it's now the expected option ;-)
5976 The manual page was adjusted accordingly.
5977 [Ralf S. Engelschall] PR#2714
5979 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
5980 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
5982 *) Removed recently introduced bugs and disfigurements in APACI:
5983 o fixed argument line processing: using $args was broken: It was not
5984 initialized and using args="$args $apc_option" and even args="$args
5985 \"$apc_option\"" fails in the second processing round for any arguments
5986 containing whitespaces. The only correct way is to use the construct
5987 "$@" (but not possible here) or iterate _both_ times over the implicit
5988 argument line (no argument to for-loop) which is what we now use.
5989 o make --with-layout=Apache the default without creating
5990 redundancy (copying the --with-layout block in the argument parsing
5991 loop). We achieve this by using the "$@" construct together with the
5992 `set' command to prepend --with-layout=Apache to the command line in
5993 case --with-layout is not used.
5994 o fixed auto-suffix handling now that config.layout exists.
5995 Paths which are auto-suffixed are marked with a trailing plus sign in
5996 config.layout and every path now can be marked this way (not only the
5997 four paths for which we do it currently). Additionally the suffix is
5998 no longer a static one. Instead it's now `/<target>' where <target> is
5999 the argument of the --target option or per default `httpd'.
6000 o allow also tabs (and only spaces) where we match whitespaces
6001 o various fixes and cleanups related to used shell coding style
6002 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
6003 o trimmed output of --help to fit into 80 columns
6004 [Ralf S. Engelschall]
6006 *) Added two new core API functions, ap_single_module_configure() and
6007 ap_single_module_init(), which are now used by mod_so to configure a module
6008 after loading. [Ralf S. Engelschall]
6010 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
6011 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
6012 of ap_config.h to allow serialized accept for multiport listens.
6013 [Roy Fielding, Curt Sampson] PR#3120
6015 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
6016 of ap_config.h that would skip several defines if DEFAULT_GROUP
6017 was overridden. [Roy Fielding]
6019 *) PORT: The I86 version of DGUX has support for strncasecmp and
6020 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
6022 *) Fix ordering of definitions in ap_config.h so that ap_inline is
6023 defined before it might be used. [Victor Khimenko]
6025 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
6026 [Tom Serkowski <tks@bsdi.com>] PR#3453
6028 *) Make generation of src/Configuration.apaci more robust: It failed to
6029 differenciate between modules when one module name was a postfix of
6030 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
6031 just XXX (think about totally non-standard names like "apache_ssl", too).
6032 [Ralf S. Engelschall] PR#3380
6034 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
6035 since 1.3b7) and make whitespace handling more robust (it failed horrible
6036 when whitespaces were present in the arguments of -D options).
6037 [Ralf S. Engelschall] PR#3240
6039 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
6040 creates an external package shadow tree in DIR before the local build
6041 shadow tree is generated under DIR. This way one can have the extracted
6042 Apache distribution tree read-only on NFS or CDROM and still build Apache
6043 from these sources. An automatically triggered VPATH-like mechanism is
6044 provided through the TOP variable, too.
6045 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
6047 *) Fix negotiation so that a Vary response header is correctly
6048 generated when, for a particular dimension, variants only vary
6049 in having or not having a value for that dimension. [Paul Sutton]
6051 *) Fix negotiation so that we prefer an encoded variant over an
6052 unencoded variant if the user-agent explicitly says it can
6053 accept that encoding. Previously we always preferred the unencoded
6055 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
6057 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
6058 and the usage page was inconsistent with the functionality and manpage.
6059 [Ralf S. Engelschall]
6061 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
6062 They can occur multiple times and their arguments (`xxx') are passed AS
6063 IS to the compiler/linker command. [Ralf S. Engelschall]
6065 *) Fixed possible (but harmless in practice) bug in the DBM lookup
6066 procedure of mod_rewrite: very long keys were truncated.
6067 [Ralf S. Engelschall]
6069 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
6070 identifier, currently "Apache" and "GNU" are pre-defined in the file
6071 config.layout. Custom layouts are possible by using FILE:ID as the
6072 argument where the layout ID is taken from FILE.
6074 The config.layout file consists of <Layout ID>..</Layout> sections
6075 where inside those sections "path_variable: path_value" pairs can be
6076 specified. These lines are converted to path_variable='path_value'.
6078 *) Add a DefaultLanguage directive so that files missing a language
6079 extension (e.g., .fr, .de) can be labelled as being some other
6080 default language. DefaultLanguage can appear in <Directory> and
6081 <Files> containers as well as .htaccess files. [Paul Sutton]
6084 *) Fix TARGET configuration when configuring and installing using
6085 APACI configure. TARGET now defines the basename of the configuration
6086 file, startup script, manual page, etc. log_error_core() now reports
6087 the server binary name given by argv[0]. TARGET can now also be defined
6088 with --target=TARGET parameter passed to APACI configure.
6089 [Ralf Engelschall, Randy Terbush]
6091 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
6092 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
6094 *) ap_md5_binary() was using sprintf() rather than a table lookup
6095 to convert binary bytes to hex digits.

6112 and a redirect at the same time. [Lars Eilebrecht]
6114 *) Fallback to native compilers for IRIX-32 platform. It seems that
6115 a gcc 2.8.1 compiled apache is logging client addresses with all
6116 bits set (255.255.255.255). This is the second such problem caused
6117 by gcc 2.8.1 compiler. The first being broken semaphore locking.
6120 *) Updated mime.types to reflect current Internet media types
6121 and include a URL to the registry.

6140 Improved mod_actions.c so that it can use any of the methods
6141 defined in httpd.h. Added ap_method_number_of(method) for
6142 getting the internal method number. [Roy Fielding]
6144 *) PORT: Add a port to the TPF OS. [Joe Moenich <moenich@us.ibm.com> and
6147 *) Fix problems with handling of UNC names (e.g., \\host\path)
6148 on Win32. [Ken Parzygnat <kparz@us.ibm.com>]
6150 *) Rework os_canonical_*() on Win32 so it's simpler, more
6151 robust, and works. [Ken Parzygnat <kparz@us.ibm.com>]
6152 PR#2555, 2915, 3064, 3232
6154 *) Work around incomplete implementation of strftime on Win32.
6155 [Manoj Kasichainula, Ken Parzygnat <kparz@us.ibm.com>]
6157 *) Move a typedef to fix compile problems on Linux with 1.x kernels.

6160 *) PORT: Add a port to the Concurrent PowerMAX OS. [Tom Horsley
6161 <Tom.Horsley@mail.ccur.com>]
6163 *) WIN32: Log more explicit error messages if spawning an interpreted
6164 script failed, including the command line used to attempt to execute
6165 the interpreter and the Win32 error code returned. [Marc Slemko]
6167 *) Disable sending of error-notes on a 500 (Internal Server Error) response
6168 since it often includes file path info. Enable sending of error-notes
6169 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
6171 *) http_config.c would respond with 501 (Method Not Implemented) if a
6172 content type handler was specified but could not be found, which
6173 should have been a 500 response. Likewise, mod_proxy.c would responsd
6174 with a 501 if the URI scheme is unrecognized instead of the correct
6175 response of 403 (Forbidden). [Roy Fielding]
6177 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
6178 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
6180 *) Fix in mod_autoindex: for files where the last modified time stamp was
6181 unavailable, an empty string was printed which was 2 bytes short.
6182 The size and description columns were therefore not aligned correctly.
6183 [Martin Kraemer] (no PR#)
6185 *) Update BS2000 OS code to work with recent versions. Starting with
6186 release A17, the child fork() must be replaced by a _rfork().
6187 (BS2000 only) [Martin Kraemer]
6189 *) Add the actual server_rec structure of the specific Vhost to the
6190 scoreboard file and avoid a string copy (as well as allow some
6191 further future enhancements). [Harrie Hazewinkel
6192 <harrie.hazewinkel@jrc.it>]
6194 *) Add APACI --permute-module=foo:bar option which can be used to
6195 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
6196 in the Configuration[.apaci] file. Two special and important variants are
6197 supported for the option argument: first BEGIN:foo which permutes module
6198 mod_foo with the begin of the module list, i.e. it `moves' the module to
6199 the begin of the list (gives it lowest priority). And second foo:END
6200 which permutes mod_foo with the end of the module list, i.e. it `moves'
6201 the module to the end of the list (gives it highest priority).
6202 [Ralf S. Engelschall]
6204 *) Fix problem with 'apache -k shutdown' and startup event
6205 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
6208 *) The config parser wasn't correctly noticing a missing '>'
6209 on container start lines (e.g., it wouldn't spot
6210 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
6213 *) Add a 'RemoveHandler' directive which will selectively remove
6214 all handler associations for the specified file extensions.
6215 [Ryan Bloom <rbbloom@us.ibm.com>] PR#1799.
6217 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
6218 ResourceConfig directives on Win32. Also add a note to the effect
6219 of 'useless User directive ignored on Win32' to the errorlog if
6220 a User directive is encountered on Win32.
6221 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2078, 2303.
6223 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
6224 broken since Apache 1.3.1 where we took out compressing of multiple
6225 spaces in ap_cfg_getline().
6226 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
6228 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
6229 initialized correctly and the db_open() call used an invalid mode
6230 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
6232 *) PORT: DSO support for UnixWare 7
6233 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
6235 *) Merge the contents of the {srm,access}.conf-dist* files into the
6236 httpd.conf-dist* files. The srm and access files now contain
6237 only comments, and httpd.conf has all the combined contents in
6238 a rational order. [Ken Coar]
6240 *) PORT: DSO/ELF support for FreeBSD 3.0.
6241 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
6243 *) Add a "default-handler" handler that calls the default_hander()
6244 function which is normally called for static content. This allows
6245 you to override a specific handler. [Marc Slemko]
6247 *) Further simplify checking for absolute paths by replacing an
6248 hard-coded syntax check with a call to a routine we already created to
6249 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
6251 *) Log an error if we encounter a malformed "require" directive
6252 in mod_auth if we know that we know that no other module can
6253 deal with it. [Marc Slemko]
6255 *) Remove ap_private_extern method of hiding conflicting symbols
6256 on the NEXT platform because it is not correct for all versions,
6257 and the versions for which it is correct are unknown.
6258 [Wilfredo Sanchez <wsanchez@apple.com>]
6260 *) Fix inheritance of IndexOptions NameWidth and remove unintended
6261 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
6263 *) Fix per-directory config merging for cases in which a 500 error
6264 is encountered in an .htaccess file somewhere down the tree.
6267 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
6269 *) Fixed a segmentation violation in mod_proxy when a response is
6270 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
6272 Changes with Apache 1.3.3
6274 *) Added a complete implementation of the Expect header field as
6275 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
6276 response when we already know the final status, which is mighty
6277 useful for PUT responses that result in 302 or 401. [Roy Fielding]
6279 *) Remove extra trailing whitespace from the getline results as part
6280 of the protocol processing, which is extra nice because it works
6281 between continuation lines, is almost no cost in the normal case
6282 of no extra whitespace, and saves memory. [Roy Fielding]
6284 *) Added new HTTP status codes and default response bodies from the
6285 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
6286 HTTP Extension Framework (510) specifications. Did not add the
6287 WebDAV 424 and 425 codes because they are bogus. We don't use any
6288 of these codes yet, but they are now available to 3rd-party modules.
6291 *) Fix a possible race condition between timed-out requests and the
6292 ap_bhalfduplex select that might result in an infinite loop on
6293 platforms that do not validate the descriptor. [Roy Fielding]
6295 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
6296 running Apache server [Paul Sutton]
6298 *) Fix mod_autoindex bug where directories got a size of "0k" instead
6299 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
6302 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
6304 *) Add the server signature text (from the core ServerSignature directive)
6305 to the list of envariables available to scripts, SSI, and the like.
6308 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
6309 [M. Laak <maert@proinv.ee>] PR#3108
6311 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
6312 calculation in mod_status for all systems which don't have POSIX
6313 sysconf() (like UTS 2.1) and not only for the NEXT platform.
6314 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
6316 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
6317 mod_auth_db by using ap_getword_white() (which uses ap_isspace())

6319 but not tabs). [James Morris <jmorris@intercode.com.au>,

6361 <steve.cameron@compaq.com>]
6363 *) Reconstructed the loop through multiple htaccess file names so
6364 that missing files are not confused with unreadable files.
6367 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
6368 errno on an error, which leads to one error being mistaken for
6369 another when reading non-existent .htaccess files.
6372 *) OS/2: The new header tests get things right, need to update
6373 ap_config.h. [Brian Havard]

6390 Changes with Apache 1.3.2
6392 *) Fix bug in ap_remove_module(), which caused problems for dso's
6393 who were the top_module. [Doug MacEachern]
6395 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
6396 mod_auth_db to both be friendly to users who wants to use this version
6397 and to avoid problems under platforms where only version 2.x is present.
6398 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
6400 *) When using ap_log_rerror(), make the error message available to the
6401 *ERROR_NOTES envariables by default. [Ken Coar]
6403 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
6404 You now must define a BS2000Account name for the server User.
6405 This has fewer security implications than the old approach.
6408 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
6409 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
6410 platform to make the braindead HPUX linker happy. Notice, for the module
6411 DSOs we don't have to use this, because these are loaded manually (and
6412 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
6414 *) Remove 64 thread limit on Win32.
6415 [Bill Stoddard <stoddard@raleigh.ibm.com>]
6417 *) Remove redundant substitutions in top-level Makefile.tmpl.
6418 [Ralf S. Engelschall]
6420 *) Fix APACI's `Group' configuration adjustment - especially for Linux
6421 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
6423 *) Make PrintPath work generically instead of having one version
6424 strictly for OS/2. [Jim Jagielski, Brian Havard]
6426 *) Fix the recently introduced C header file checking: We now use the C
6427 pre-processor pass only (and no longer the complete compiler pass) to
6428 determine whether a C header file exists or not. Because only this way
6429 we're safe against inter-header dependencies (which caused horrible
6430 portability problems). The only drawback is that we now have a CPP
6431 configuration variable which has to be determined first (we do a similar
6432 approach as GNU Autoconf does here). When all fails the user still has
6433 the possibility to override it manually via APACI or src/Configuration.
6434 As a fallback for the header check itself we can directly check the
6435 existance of the file under /usr/include, too.
6436 [Ralf S. Engelschall] PR#2777
6438 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
6439 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
6440 ap_private_extern defined to hide symbols that conflict with loaded
6441 dynamic libraries on the NEXT and RHAPSODY platforms.

6460 used -lprot. It's actually a bug in SCO5, of course.

6463 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
6464 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
6466 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
6467 platform, because it's only supported under version 4.0 and higher. But
6468 because our GuessOS is still unaware of Digital UNIX versions and the
6469 -msym is just to optimize the DSO statup time a little bit it's safe and
6470 best when we leave it out now. [Ralf S. Engelschall] PR#2969
6472 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
6473 functions: First all three functions no longer fail on strings containing
6474 "%" chars and second ap_log_printf() no longer does a double-formatting
6475 (instead it directly passes through the message to be formatted to the
6476 real internal formatting function). [Ralf S. Engelschall] PR#2941
6478 *) Allow "Include" directives anywhere in the server config
6479 files (but not .htaccess files). [Ken Coar] PR#2727
6481 *) The proxy was refusing to serve CONNECT requests except to
6482 port 443 (https://) and 563 (snews://). The new AllowCONNECT
6483 directive allows the configuration of the ports to which a
6484 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
6486 *) mod_expires will now act on content that is not sent from a file
6487 on disk. Previously it would never add an Expires: header to
6488 any response that did not come from a file on disk; the only
6489 case where it still doesn't (and can't) add one for that type of
6490 content is if you are using a modification date based setting.
6491 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
6493 *) Problems encountered during .htaccess parsing or CGI execution
6494 that lead to a "500 Server Error" condition now provide explanatory
6495 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
6498 *) Add NameWidth keyword to IndexOptions directive so that the
6499 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
6502 *) Recognize lowercase _and_ uppercase `uname' results under
6503 SCO OpenServer. [David Coelho <drc@ppt.com>]
6505 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
6506 a common problem of (mis-administrated?) IIS servers, make the apache
6507 proxy immune to these errors (and ignore the duplicates, but log
6508 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
6510 *) The <IfModule and <IfDefine block starting directives now only
6511 allow exactly one argument. Previously, the optional negation
6512 character '!' could be separated by whitespace without a syntax
6513 error being reported, albeit defeating the IfModule functionality
6514 (enclosed directives would ALWAYS be executed). By using the
6515 stricter syntax, these hard-to-track errors can be avoided.
6518 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
6519 cause the standalone FancyIndexing directive to logically OR
6520 into any existing IndexOptions settings rather than wiping
6521 them out. [Ken Coar]
6523 *) Changes in ftp proxy: make URL parsing simpler by using the
6525 + Add display of the "current directory" in cases where it's
6526 different from the supplied path (e.g., ftp://user@host/ lives
6527 in /home/user, not in /, therefore clicking on "../" in the
6528 starting directory might send us to /home/).
6529 + When ftp login fails, (esp. when a user name was part of the
6530 URL already), we now return [401 Unauthorized ] to allow the
6531 browser to pop up an authorization dialog. This makes passwords
6532 slightly less visible (they don't appear in the regular log files)
6533 and implements a functionality that other www proxy servers
6537 *) Triggered by the recent "Via:" header changes, the proxy module would
6538 dump core for replies with invalid headers (e.g., duplicate
6539 "HTTP/1.0 200 OK" lines). These errors are now logged and the
6540 core dump is avoided. Also, broken replies are not cached.
6541 [Martin Kraemer] PR#2914
6543 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
6544 plop gmon.out profile data for each child [Doug MacEachern]
6546 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
6547 config.status script to be immune against arguments with whitespaces.
6548 [Yves Arrouye <yves@apple.com>] PR#2866
6550 *) Replace the inlined information grabbing stuff for the configuration
6551 adjustment feature (no --without-confadjust) with calls to a new helper
6552 script `buildinfo.sh' which is both more flexible and already proofed to
6553 be more robust against platform differences. This mainly fixes the
6554 recently occured ``sed: command garbled: ...'' problems.
6555 [Ralf S. Engelschall] PR#2776, PR#2848

6559 without complains after we recently added the POST feature.
6560 [Ralf S. Engelschall]

6572 *) Add the ability to do POST requests to the ab benchmarking tool.
6573 [Kurt Sussman <kls@best.com>] PR#2871
6575 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
6576 5 to 10 because there are some users out there who always have 5 to 8
6577 variables in one RewriteRule and had to patch mod_rewrite.h for every
6578 release. So 15 should be now more than enough, even for them. (I never
6579 needed more than 4 in my RewriteRules ;-)
6580 [Ralf S. Engelschall]
6582 *) Make the proxy generate and understand Via: headers
6585 *) Change the proxy to use tables instead of array_headers for
6586 the header lines. [Martin Kraemer]
6588 *) Make sure the config.status file is not overridden when just
6589 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
6591 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
6592 provide a way to trace API changes that add functionality but do
6593 not create a compatibility issue for precompiled modules, etc.
6594 See include/ap_mmn.h for more details. [Randy Terbush]
6596 *) Fix suexec installation under `make install root=xxx' situation.
6597 [Ralf S. Engelschall]
6599 *) Extend the output of the -V switch to include the paths of all
6600 compiled-in configuration files, if they were overridden at
6601 compile time, for least astonishment of the user.
6604 *) When READing a request in ExtendedStatus mode, the "old"
6605 vhost, request and client information is not displayed.
6608 *) STATUS is no longer available. Full status information now
6609 run-time configurable using the ExtendedStatus directive.
6612 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
6613 cpu time attacks) in header parsing. Add ap_overlap_tables(),
6614 a function which can be used to perform bulk update operations
6615 on tables in a more efficient manner. [Dean Gaudet]
6617 *) SECURITY: Added compile-time and configurable limits for
6618 various aspects of reading a client request to avoid some simple
6619 denial of service attacks, including limits on maximum request-line
6620 size (LimitRequestLine), number of header fields (LimitRequestFields),
6621 and size of any one header field (LimitRequestFieldsize). Also added
6622 a configurable directive LimitRequestBody for limiting the size of the
6623 request message body. [Roy Fielding]

6626 STATUS not defined. [Jim Jagielski]

6642 state even without full STATUS accounting. [Jim Jagielski]

6673 This is done by determining a subset of LIBS which can be safely used for
6674 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
6675 disabled for all platforms to avoid problems with this (experimental)
6676 rule. But we provide it now for those people how ran into problems and

6810 Backward compatibility files for conf.h and compat.h were created.
6812 *) mod_mmap_static will no longer take action on requests unless at
6813 least one "mmapfile" directive is present in the configuration.
6814 This experimental module has to do some black magic to operate
6815 inside the current API and thus creates side-effects for other

6986 *) Improve performance of directory listings (mod_autoindex) by comparing
6987 integer keys (last-modified and size) as integers rather than converting
6988 them to strings first. Also use a set of explicit byte tests rather
6989 than strcmp() to check for parent directory-ness of an entry. Oh, and
6990 make sure the parent directory (if displayed) is *always* listed first
6991 regardless of the sort key. Overall performance winnage should be good
6992 in CPU time, instruction cache, and memory usage, particularly for large
6993 directories. [Ken Coar]

6996 of a config.status script (as GNU Autoconf does) which remembers the used
6997 configure command and hence can be used to restore the configuration by
6998 just re-running this script or for remembering the configuration between

7002 *) Add httpd -t (test) option for running configuration syntax tests only.
7003 If something is broken it complains and exits with a return code
7004 non-equal to 0. This can be used manually by the user to check the Apache
7005 configuration after editing and is also automatically used by apachectl
7006 on (graceful) restart command to make sure Apache doesn't die on restarts
7007 because of a configuration which is now broken since the last (re)start.
7008 This way `apachectl restart' can be used inside cronjobs without having
7009 to expect Apache to be falling down. Additionally the httpd -t can be run

7131 in mod_mime, mod_log_referer, mod_log_agent, and mod_log_config.
7134 *) Various OS/2 cleanups ["Brian Havard" <brianh@kheldar.apana.org.au>]
7136 *) PORT: QNX needed a #include <sys/mman.h>; and now it uses flock
7137 serialized accept to handle multiple sockets.

7144 *) Propagate environment to CGI scripts correctly in Win32.
7145 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
7147 *) Some symbol renaming:
7148 ap_spawn_child_err became ap_spawn_child
7149 ap_spawn_child_err_buff became ap_bspawn_child
7150 spawn_child was obsoleted and moved to compat.h
7153 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
7154 programs: ap_spawn_child_err() is used and the Win32 case now uses
7155 CreateProcess() instead of a low-level execl() (which caused problems in
7156 the past under Win32).
7157 [Ralf S. Engelschall]
7159 *) A few cosmetics and trivial enhancements to APXS to make the
7160 generated Makefile more user friendly. [Ralf S. Engelschall]
7162 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
7163 was updated to use the normal apache error processing, thereby allowing
7164 proxy errors to be treated by ErrorDocument's as well. For this
7165 purpose, a new module-to-core communication variable "error-notes"
7166 was introduced; the proxy (and possibly other modules) communicates
7167 its error text using this variable. Its content is copied to a new
7168 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
7169 The old proxy special error routine ap_proxy_log_uerror()
7170 was replaced by regular ap_log_error() calls, many messages were made
7172 [Martin Kraemer] PR#494, 1259
7174 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
7177 *) Transform the configure message "You need root privileges for suEXEC"
7178 from a fatal error into a (more friendly) warning because the building
7179 ("make") of Apache we can allow, of course. Root privileges are needed
7180 only for the installation step ("make install"). So make sure the
7181 user is aware of this fact but let him proceed as long as he can.

7184 *) Renamed three more functions to common ap_ prefix which we missed at the
7185 Big Symbol Renaming because they're #defines and not real C functions:

7202 *) Make sure a MIME-type can be forced via a RewriteRule even when no
7203 substitution takes place, for instance via the following rule:
7204 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
7205 requested by users in the past to force a single script without a .cgi
7206 extension and outside any cgi-bin dirs to be executed as a CGI program.

7215 trying to connect to certain ftpd's, such as anonftpd.
7216 [Rick Ohnemus <rick@ecompcon.com>]
7218 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
7219 logfile instead of fiddling around itself with child spawning stuff.
7220 [Ralf S. Engelschall]
7222 *) Made RefererIgnore case-insensitive.
7224 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
7227 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
7228 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
7231 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]

7234 of passwords, especially passwords with "0" chars.

7238 [Ben Laurie] PR#2238
7240 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
7241 library), so CGI handling has been changed to use Win32 native handles
7242 instead of C file descriptors.
7243 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
7245 *) The proxy cache would store an incorrect content-length in the cached
7246 file copy after a cache update. That resulted in repeated fetching
7247 of the original copy instead of using the cached copy.
7248 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
7250 *) The Makefiles assumed that DSO files are build via $(LD). This
7251 is broken for two reasons: First we never defined at least LD=ld
7252 somewhere to make sure this works (it was silently assumed that most Make
7253 provide a built-in LD definition - ARGL!) and second using the generic LD
7254 variable is not the truth. Instead a special variable named LD_SHLIB is
7255 reasonable because although "ld" is usually the default, the command for
7256 building DSO files can be "libtool" or even "cc" on some systems.
7257 [Ralf S. Engelschall]
7259 *) Replace the AddVersionPlatform directive with ServerTokens which
7260 provides for more control over the format of the Server:
7261 header line. SERVER_SUBVERSION is no longer supported;
7262 all module should use the ap_add_version_component()
7263 API function instead. [Jim Jagielski]
7265 *) Support for the NCR MP/RAS 3.0
7266 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
7268 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
7269 not retrieved in src/Configure and thus was not useable.
7270 [Ralf S. Engelschall]
7272 *) Various Makefile consistency cleanups:
7273 - make OSDIR also automatically be relative to src/ like INCDIR
7274 - SUBDIRS is now generated in src/Makefile only and not in
7275 Makefile.config because it is a local define for this location.
7276 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
7277 any Makefile but make sure that at least the "-K inline" is kept in
7279 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
7280 - updated the dependencies theirself
7281 - removed not existing SHLIB variable from "clean" targets
7282 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
7283 already exists and OBJS_PIC are also just plain objects and have not
7284 directly to do with "shared" things. The only difference is that they
7285 contain PIC. So OBJS_PIC is the more canonical name.
7286 - Updated the Makefile-dependency lines for OBJS_PIC
7287 - Removed the Makefile-dependency line in Configure to avoid double
7289 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
7290 of xxx.lo as GNU libtool does with its PIC objects
7291 - reduce local complexity in modules Makefile.tmpl by moving the last
7292 existing target "depend" to the generation section in Configure, too.
7293 - removed the historical $(SPACER) which was used in the past together
7294 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
7295 is no longer needed.
7296 - force the build and run of the gen_xxx programs under main/ as the
7297 first step before building the objects because it looks cleaner
7298 [Ralf S. Engelschall]
7300 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
7303 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
7306 *) WIN32: Don't force ISAPI headers to finish with \n.
7307 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
7309 *) When opening "configuration" files (like httpd.conf, htaccess
7310 and htpasswd), Apache will not allow them to be non-/dev/null
7311 device files. This closes a DoS hole. At the same time,
7312 we use ap_pfopen to open these files to handle timeouts.
7313 [Jim Jagielski, Martin Kraemer]
7315 *) Apache will now log the reason its httpd children exit if they exit
7316 due to an unexpected signal. (It requires a new porting define,
7317 SYS_SIGLIST, which if defined should point to a list of text
7318 descriptions of the signals available. See PORTING.) [Dean Gaudet]
7320 *) WIN32: chdir() doesn't make sense in a multithreaded environment
7321 like WIN32. Before, Win32 CGI's could have had sporadic failures
7322 if a chdir call from one thread was made between another chdir call
7323 and a spawn in another thread. So, for now don't chdir for CGI scripts
7324 in WIN32. The current CGI "spec" is unclear as to whether it's
7325 necessary. Long-term fix is to either serialize the chdir/spawn combo
7326 or use WIN32 native calls to spawn a process. This temp fix was
7327 necessary to remove this as a showstopper for 1.3's release.
7330 *) Cleanup the suEXEC support in APACI and make it more safe:
7331 1. Add big fat hint in INSTALL about risks and to read the
7332 htdocs/manual/suexec.html document before using the suexec-related
7334 2. Make sure the user has at least provided one --suexec-xxxx option
7335 (specifies suEXEC parameters) in addition to --enable-suexec option.
7336 If only --enable-suexec is given APACI stops with a hint to INSTALL
7337 and htdocs/manual/suexec.html documents.
7338 3. Provide two additional --suexec-xxxx options to make the suEXEC
7339 configuration complete (especially for package maintainers who else
7340 had to patch the source tree) by providing ways to configure minimal
7341 UID/GID and safe PATH, too.
7342 [Ralf S. Engelschall]
7344 *) Cleanup of the `configure --shadow' process:
7345 - make sure the configure script creates its temporary files in the
7346 shadow tree to avoid conflicts with parallel configure runs
7347 - removed unnecessary option "-r" from "rm" call for Makefiles
7348 - make sure the configure scripts creates the shadow-wrapper Makefile
7349 only when no shadow trees already exists
7350 - make sure "make distclean" removes the shadow-wrapper Makefile but only
7351 when no more shadow trees exists
7352 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
7353 as fast (in the past it needed 70sec, now it runs just 38sec)
7354 - make sure CVS does not complain about the created files
7355 Makefille.<gnutriple> and directories src.<gnutriple>
7356 [Ralf S. Engelschall]
7358 *) Added the ap_add_version_component() API routine and the
7359 AddVersionPlatform core directive. The first allows modules to
7360 declare themselves in the Server response header field value,
7361 augmenting the SERVER_SUBVERSION define in the Configuration file
7362 with run-time settings (more useful in a loadable-module environment).
7363 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
7364 into the server version string. [Ken Coar] PR#2056
7366 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
7369 *) Emit the "Accept-Range" header for the default handler.
7370 [Brian Behlendorf] PR#1464
7372 *) Add a note to httpd.conf-dist that apache will on some systems fail
7373 to start when the Group # is set to a negative or large positive value.
7376 *) Make sure the module execution order is correct even when some modules
7377 are loaded under runtime (`LoadModule') via the DSO mechanism:
7378 1. The list of loaded modules is now a dynamically allocated one
7379 and not the original statically list from modules.c
7380 2. The loaded modules are now correctly setup by LoadModule for
7381 later use by the AddModule command.
7382 3. When the DSO mechanism for modules is used APACI's `install'
7383 target now enables all created `LoadModule' lines per default because
7384 this is both already expected by the user _and_ needed to avoid
7385 confusion with the next point and reduces the Makefile.tmpl complexity
7386 4. When the DSO mechanism for modules is used, APACI's `install'
7387 target now additionally makes sure the module list is reconstructed
7388 via a complete `ClearModuleList+AddModule...' entry.
7389 5. The support tool `apxs' now also makes sure an AddModule command
7390 is added in addition to the LoadModule command.
7391 6. The modules.c generation was extended to now contain two
7392 comments to make sure no one is confused by the confusing terminology
7393 of loading/linking (we use load=link+load & link=activate instead of
7394 the obvious load=activate & link=link :-( )
7395 This way now there is no longer a difference under execution time between
7396 statically and dynamically linked modules.
7397 [Ralf S. Engelschall]
7399 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
7400 Big Symbol Renaming. [Ralf S. Engelschall]
7402 *) Add a comment to mod_example.c showing the format of a FLAG command
7405 *) Standardized the time format in mod_status to match that of other
7406 places in the code (e.g. DATE_GMT). PR#1551
7408 *) Fix handling of %Z in timefmt strings for those platforms with no time
7409 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
7412 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
7413 feature compatible with 'UseCanonicalName off' by changing
7414 r->server->server_hostname to ap_get_server_name(). And I changed some
7415 functions which use r->server->port to use ap_get_server_port() instead,
7416 because if there's no Port directive in the config r->server->port is 0.
7419 *) get/set_module_config are trivial enough to be better off inline. Worth
7420 1.5% performance boost. [Dean Gaudet]
7422 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
7423 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
7426 *) [BS2000 security] BS2000 needs an extra authentication to initialize
7427 the task environment to the unprivileged User id. Otherwise CGI scripts
7428 would have a way to gain super user access. [Martin Kraemer]
7430 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
7431 absolute path, only log base name of logging source as is done
7432 in unix. [Martin Kraemer]
7434 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
7435 the encoding type from the Accept-Encoding header (if it's there)
7436 and use it in the response, as that's probably what it'll be expecting.
7437 [Ronald.Tschalaer@psi.ch]
7439 *) Fix to mod_alias: translate_alias_redir is dealing with
7440 a URI, not a filename, so the check for drive letters for win32
7441 and emx is not necessary. [Dean Gaudet]
7443 *) WIN32: Allow .cmd as an executable extension.
7444 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
7446 *) Make Apache header files, and some variables, C++ friendly.
7447 [Michael Anderson's <mka@redes.int.com.mx>]
7449 *) Child processes can now "signal" (by exiting with a status
7450 of APEXIT_CHILDFATAL) the parent process to abort and
7451 shutdown the server if the error in the child process was
7452 fatal enough. [Jim Jagielski]
7454 *) mod_autoindex's find_itme() was sensitive to MIME type case.
7455 [Jim Jagielski] PR#2112
7457 *) Make sure the referer_log and agent_log entries in the default httpd.conf
7458 file are also adjusted for the actual relative installation paths.
7459 [Ralf S. Engelschall] PR#2175
7461 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
7463 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
7466 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
7467 Additionally the checks for finding the vendor DSO library were moved
7468 from mod_so.c to Configure because first it needs $PLAT etc. and second
7469 mod_so already uses an abstraction layer and does not fiddle with the
7470 vendor functions itself.
7471 [Jens-Uwe Mager, Ralf S. Engelschall]
7473 *) PORT: Some optimization defines for NetBSD
7474 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
7476 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
7477 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
7479 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
7480 AIX variants should work fine, too. Even AIX 3.x should work). This is
7481 accomplished by using the free DSO emulation code from Jens-Uwe Mager
7482 which we put into a os/unix/os-dso-aix.c file.
7483 [Ralf S. Engelschall]
7485 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
7486 that we should use NET_SIZE_T == int but the include files force size_t.
7487 [Ralf S. Engelschall]
7489 *) Fix two bugs in select() handling in http_main.c.
7492 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
7493 is unset (as it is in situations like timeouts) where it is unclear
7494 whether errno is set or not. [Martin Kraemer]
7496 *) Just having APACI's localstatedir is too general and not enough for most
7497 of the systems. 1.3b6 again required manual APACI patches by package
7498 maintainers from Red Hat and FreeBSD because for their filesystem layout a
7499 little bit more flexibility in configuring the paths is needed. Hence we
7500 provide three additional configure options (--runtimedir, --logfiledir,
7501 --proxycachedir) which now can be used for more granular adjustments if
7502 --localstatedir is not enough to fit the particular needs. As a nice
7503 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
7504 [Ralf S. Engelschall]
7506 *) Make the install root for "make install" in APACI's Makefile overrideable
7507 by package authors. This way we are even more friendly to package
7508 maintainers (especially Debian and Red Hat) who build for the real prefix
7509 via "configure --prefix=/<real>" but use a different local prefix via
7510 "make root=/tmp/apache install" for rolling the package without bristling
7511 the target location on their system.
7512 [Ralf S. Engelschall]
7514 *) Workaround sed limitations in APACI's configure script by now
7515 substituting in chunks of 50 commands (because for instance HPUX's vendor
7516 sed has a limit of max. 98 commands)
7517 [Ralf S. Engelschall] PR#2136
7519 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
7520 [Ralf S. Engelschall] PR#2140
7522 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
7523 RENAMING process because they are defined as pre-processor macros instead
7524 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
7525 [Ralf S. Engelschall]
7527 *) Workaround braindead AWK's when generating ap_config.h: The split() and
7528 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
7529 [Ralf S. Engelschall] PR#2139
7531 *) Various bugfixes and cleanups for the APACI configure script:
7532 o fix IFS handling for _nested_ situation
7533 o fix Perl interpreter search: take first one found instead of last one
7534 o fix DSO consistency check
7535 o print error messages to stderr instead of stdout
7536 o add install-quiet for --shadow situation to Makefile stub
7537 o reduce complexity by avoiding sed-hacks for rule and module list loops
7538 [Ralf S. Engelschall]
7540 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
7542 *) Make sure the input field separator (IFS) shell variable is explicitly
7543 initialized correctly before _every_ `for' loop and also restored after
7544 the loops. [Ralf S. Engelschall]
7546 *) Make sure that "make install" doesn't overwrite the `mime.types' and
7547 `magic' files from an existing Apache installation. Because people often
7548 customize these for own MIME and content types.
7549 [Ralf S. Engelschall]
7551 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
7552 [Peter Galbavy, Ralf S. Engelschall] PR#2109
7554 *) Fix the path to the ScoreBoardFile in the install-config target, too.
7555 [Ralf S. Engelschall] PR#2105
7557 *) Let "configure" clear out the users parameters (provided as shell
7558 variables) to avoid side-effects in "src/Configure" when the user
7559 exported them (which is not needed, but some users do it).
7560 [Ralf S. Engelschall] PR#2101
7562 *) Provide backward compatibility from some old src/Configuration.tmpl
7563 parameter names to the canonical Autoconf-style shell variable names. For
7564 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
7565 but a hint message is displayed. [Ralf S. Engelschall]

7568 CGI scripts from an existing Apache installation.
7569 [Ralf S. Engelschall, Jim Jagielski] PR#2084
7571 *) Make `configure --compat' more "compatible" by first
7572 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
7573 second by making sure the "avoid-bristling-suffix" /apache is not
7574 appended to sysconfdir, datadir, localstatedir and includedir when
7575 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
7577 *) NeXT required strdup() in support/logresolve.c

7583 *) Fix the path to the MimeMagicFile in the install-config target, too.
7584 [Ralf S. Engelschall] PR#2089
7586 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
7588 *) If you start apache with the -S command line option it will dump
7589 out the parsed vhost settings. This is useful for folks trying
7590 to figure out what is wrong with their vhost configuration.
7591 (Other dumps may be added in the future.) [Dean Gaudet]
7593 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
7594 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
7597 *) Because /usr/local/apache is the default prefix the ``configure
7598 --compat'' option no longer has to set prefix, again. This way the
7599 --compat option honors a leading --prefix option. [Lars Eilebrecht]
7601 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
7602 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
7603 to avoid "discard const" warnings. [Ralf S. Engelschall]
7605 *) If a specific handler is set for a file yet the request still
7606 ends up being handled by the default handler, log an error
7607 message before handling it. This catches things such as trying
7608 to use SSIs without mod_include enabled. [Marc Slemko]
7610 *) Fix error logging for the startup case where ap_log_error() still uses
7611 stderr as the target. Now the default log level is honored here, too.
7612 [Ralf S. Engelschall]
7614 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
7615 long" errors when generating the MODULES entry for src/Makefile
7616 [Ben Hyde, Ralf S. Engelschall]
7618 *) Make sure src/Configure doesn't complain about the old directory
7619 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]

7623 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
7625 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
7626 interface via the similar but proprietary HP/UX shl_xxx-style system
7627 calls. [Ralf S. Engelschall]
7629 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
7630 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
7631 Make. [Ralf S. Engelschall]
7633 *) ++++ THE BIG SYMBOL RENAMING ++++
7634 To avoid symbol clashes with third-party code compiled into the server,
7635 we globally applied the prefix "ap_" to the following classes of
7637 - Apache provided general functions (e.g., ap_cpystrn)
7638 - Public API functions (e.g., palloc, bgets)
7639 - Private functions which we can't make static (because of
7640 cross-object usage) but should be (e.g., new_connection)
7641 For backward source compatibility a new header file named compat.h was
7642 created which provides defines for the old symbol names and can be used
7643 by third-party module authors.
7646 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
7647 problem under SVR4 is that there is no command flag to force the linker
7648 to export the global symbols of the httpd executable therewith they are
7649 available to the DSO's. Instead of problematic hacks like creating a
7650 dummy.so file (containing dummy references to all global symbols) the
7651 httpd binary is linked against, we use a clean trick stolen from Perl 5:
7652 Placing the Apache core code itself into a DSO library named libhttpd.so.
7653 This way the global symbols _HAVE_ to be exported and thus are available
7654 to any manually loaded DSO's under runtime. To reduce the impact to the
7655 user to null we go even further and create a stub httpd executable which
7656 automatically keeps track of the DSO library loading itself and thus
7657 hides the complete mechanism from the user. Although the generation of
7658 this DSO library is automatically triggered for platforms which
7659 essentially need it (mostly all SVR4-derivates) it can be also enabled
7660 manually via the Rule SHARED_CORE. This can be interesting in the future
7661 where we perhaps exploit this libhttpd.so mechanism for providing nifty
7662 features like graceful upgrades, or whatever.
7663 [Ralf S. Engelschall, Martin Kraemer]
7665 *) Build the libraries before building the rest of the tools. [Ben Hyde]
7667 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
7668 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
7669 conventions while "clean" removes only stuff created by "all" targets,
7670 "distclean" additionally removes the stuff from the configuration
7671 process. This way "make distclean" (hence the name) provides a fresh
7672 source tree as it was for distribution.
7673 [Ralf S. Engelschall]
7675 *) Allow top-level (APACI) Makefile to break on build errors
7676 the same way the src/ subtree Makefiles breaks on them by replacing the
7677 initial APACI sed-subdir-display-kludge with a more clean
7678 variable-passing-solution: variable SDP can optionally hold the subdir
7679 prefix which is consistently used for displaying the subdir movement.
7680 This way even the top-level Makefile can stop correctly on errors as the
7681 user expects. [Ralf S. Engelschall]
7683 *) Fixed ordering of argument checks for RewriteBase directive.
7684 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
7686 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
7687 indicating that a module is being compiled for dynamic loading. Also
7688 remove #define IS_MODULE from modules and add SHARED_MODULE define
7689 to the mak/dsp files. [Alexei Kosut]
7691 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
7692 since we are now logging APLOG_WARNING by default. [Roy Fielding]
7694 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
7696 *) Add documentation file and src/Configuration.tmpl entry for the
7697 experimental mod_mmap_static module. Because although it is and marked as
7698 an experimental one it is distributed and thus should be documented and
7699 prepared for configuration the same way as all others modules.
7700 [Ralf S. Engelschall]
7702 *) Add query (-q) option to apxs support tool to be able to manually query
7703 specific settings from apxs. This is needed for instance when you
7704 manually want to access Apache's header files and you need to assemble
7705 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
7706 [Ralf S. Engelschall]
7708 *) Now src/Configure uses a fallback strategy for the shared object support
7709 on platforms where no explicit information is available: If a Perl
7710 installation exists we ask it about its shared object support and if it's
7711 the dlopen-style one we shamelessly guess the compiler and linker flags
7712 for creating shared objects from Perls knowledge. Of course, the user is
7713 warning about what we are doing and informed that he should send us
7714 the guessed flags when they work. [Ralf S. Engelschall]
7716 *) Provide APACI --without-support option to be able to disable the build
7717 and installation of the support tools from the src/support/ area.
7718 Although its useful to have these installed per default we should provide
7719 a way to compile and install without them for backward-compatibility.
7720 [Ralf S. Engelschall]
7722 *) Add of the new APache eXtenSion (apxs) support tool for building and
7723 installing modules into an _already installed_ Apache package through the
7724 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
7725 this approach actually doesn't need the Apache source tree. The
7726 (APACI-installed) server package is enough, because this now includes the
7727 Apache C header files (PREFIX/include) and the new APXS tool
7728 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
7729 module authors to build their Apache modules _OUTSIDE_ the Apache source
7730 tree while avoiding them to fiddle around with the totally platform
7731 dependend way of compiling DSO files. The tool supports all ranges of
7732 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
7733 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
7734 on-the-fly generate a minimalistic Makefile and sample module for the
7735 first step to provide both a quick success event and to demonstrate the
7736 APXS mechanism to module authors. [Ralf S. Engelschall]
7738 *) Fix core dumps in use of CONNECT in proxy.
7739 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
7741 *) Modify the log directives in httpd.conf-dist files to use CustomLog
7742 so that users have examples of how CustomLog can be used.
7745 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
7746 the Apache distribution tree. Until Apache 1.3 there was no real
7747 out-of-the-box batch-capable build and installation procedure for the
7748 complete Apache package. This is now provided by a top-level "configure"
7749 script and a corresponding top-level "Makefile.tmpl" file. The goal is
7750 to provide a GNU Autoconf-style frontend which is capable to both drive
7751 the old src/Configure stuff in batch and additionally installs the
7752 package with a GNU-conforming directory layout. Any options from the old
7753 configuration scheme are available plus a lot of new options for flexibly
7754 customizing Apache. [Ralf S. Engelschall]
7756 *) The floating point ap_snprintf code wasn't threadsafe.
7757 Had to remove the HAVE_CVT macro in order to do threadsafe
7758 calling of the ?cvt() floating point routines. [Dean Gaudet]
7760 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
7762 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
7763 [Jim Jagielski] PR#1901
7765 *) BUG: Configure was using TCC and CC inconsistently. Make sure
7766 Configure knows which CC we are using. [Jim Jagielski]
7768 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
7769 was defined in a parent directory. [Lars Eilebrecht]
7771 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
7772 a generic printf-style routine that can call arbitrary output
7773 routines. Use this to replace http_bprintf.c. Add new routines
7774 psprintf(), pvsprintf() which allocate the exact amount of memory
7775 required for a string from a pool. Use psprintf() to clean up
7776 various bits of code which used ap_snprintf()/pstrdup().
7779 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
7780 ap_snprintf() has different semantics and formatting codes than
7781 snprintf(). [Dean Gaudet]
7783 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
7784 is necessary on at least Solaris where the /etc/rc?.d scripts
7785 are run with these signals ignored, and "SIG_IGN" settings are
7786 maintained across exec().
7787 [Rein Tollevik <reint@sys.sol.no>] PR#2009
7789 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
7790 used instead of lstat() and thus this flag didn't work as expected.
7791 [Rein Tollevik <reint@sys.sol.no>] PR#2010
7793 *) Fix the proxy pass-through feature of mod_rewrite for the case of
7794 existing QUERY_STRING now that mod_proxy was recently changed because of
7795 the new URL parsing stuff. [Ralf S. Engelschall]
7797 *) A few changes to scoreboard definitions which helps gcc generate
7798 better code. [Dean Gaudet]
7800 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
7801 be a signed bitfield. So mark a few bitfields as signed to
7802 ensure correct code. [Dean Gaudet]
7804 *) The default for HostnameLookups was changed to Off, but there
7805 was a problem and it wasn't taking effect. [Dean Gaudet]
7807 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
7810 *) After a SIGHUP the listening sockets in the parent weren't
7811 properly marked for closure on fork().
7812 [Jürgen Keil <jk@tools.de>] PR#2000
7814 *) Allow %2F in two situations: 1) it is in the query part of the URI,
7815 therefore not exposed to %2F -> '/' translations and 2) the request
7816 is a proxy request, so we're not dealing with a local resource anyway.
7817 Without this, the proxy would fail to work for any URL's with
7818 %2f in them (occurs quite often in
7819 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
7821 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
7823 *) Make the shared object compilation command more portable by avoiding
7824 the direct combination of `-c' & `-o' which is not honored by some
7825 compilers like UnixWare's cc. [Ralf S. Engelschall]
7827 *) WIN32: the proxy was creating filenames missing the last four
7828 characters. While this normally doesn't stop anything from
7829 working, it can result in extra collisions.
7830 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
7832 *) Now mod_proxy uses the response string (in addition to the response status
7833 code) from the already used FTP SIZE command to setup the Content-Length
7834 header if available. [Ralf S. Engelschall] PR#1183
7836 *) Reanimated the (still undocumented) proxy receive buffer size directive:
7837 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
7838 name was really too generic, added documentation for this directive to
7839 the mod_proxy.html and corrected the hyperlink to it in the
7840 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
7842 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
7843 faster [Martin Kraemer]
7845 *) Make Configure die when you give it an unknown command switch.
7848 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
7849 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
7850 and per default compiled support programs have manual pages - just to
7851 document our stuff a little bit more and to be able to do really
7852 Unix-like installations ;-) [Ralf S. Engelschall]
7854 *) Major cleanups to the Configure script to make it and its generated
7855 Makefiles again readable and maintainable: add SRCDIR option, removed
7856 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
7857 generated sections, consequently added Makefile headers with inheritance
7858 information, added subdir movement messages for easier following where
7859 the build process currently stays (more verbose then standard Make, less
7860 verbose than GNU make), same style to comments in the Configure script,
7861 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
7863 *) Add the new ApacheBench program "ab" to src/support/: This is derived
7864 from the ZeusBench benchmarking program and can be used to determine the
7865 response performance of an Apache installation. This version is
7866 officially licensed with Zeus Technology, Ltd. See the license agreement
7867 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
7868 [Ralf S. Engelschall]
7870 *) API: Various core functions that are definately not part of the API
7871 have been made static, and a few have been marked API_EXPORT. Still
7872 more have been marked CORE_EXPORT and are not intended for general
7873 use by modules. [Doug MacEachern, Dean Gaudet]
7875 *) mod_proxy was not clearing the Proxy-Connection header from
7876 requests; now it does. This did not violate any spec, however
7877 causes poor interactions when you are talking to remote proxies.
7878 [Marc Slemko] PR#1741
7880 *) Various cleanups to the command line interface and manual pages.
7881 [Ralf S. Engelschall]
7883 *) cfg_getline() was not properly handling lines that did not end
7884 with a line termination character. [Marc Slemko] PR#1869, 1909
7886 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
7888 *) Clean up some undocumented behavior of mod_setenvif related to
7889 "merging" two SetEnvIf directives when they match the same header
7890 and regex. Document that mod_setenvif will perform comparisons in
7891 the order they appear in the config file. Optimize mod_setenvif by
7892 doing more work at config time rather than at runtime.
7895 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
7896 to allow for modules to overrule them and to reduce redefinition
7897 warnings [Jim Jagielski]
7899 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
7902 *) Making the hard-coded cross-module function call mime_find_ct() (from
7903 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
7904 checking is really called even for proxy requests except for URLs with
7905 HTTP schemes (because there we can optimize by not running the type
7906 checking hooks due to the fact that the proxy gets the MIME Content-type
7907 from the remote host later). This change cleans up mod_mime by removing
7908 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
7909 especially unbundles mod_proxy and mod_mime. This way they both now can
7910 be compiled as shared objects and are no longer tied together.
7911 [Ralf S. Engelschall]
7913 *) util.c cleanup and speedup. [Dean Gaudet]
7915 *) API: Clarification, pstrndup() will always copy n bytes of the source
7916 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
7918 *) Mark module command_rec and handler_rec structures const so that they
7919 end up in the read-only data section (and are friendlier to systems
7920 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
7922 *) Add check to the "Port" directive to make sure the specified
7923 port is in the appropriate range. [Ben Hyde]
7925 *) Performance improvements to invoke_handler().
7926 [Dmitry Khrustalev <dima@bog.msu.su>]
7928 *) Added support for building shared objects even for library-style modules
7929 (which are built from more than one object file). This now provides the
7930 ability to build mod_proxy as a shared object module. Additionally
7931 modules like mod_example are now also supported for shared object
7932 building because the generated Makefiles now no longer assume there is at
7933 least one statically linked module. [Ralf S. Engelschall]
7935 *) API: Clarify usage of content_type, handler, content_encoding,
7936 content_language and content_languages fields in request_rec. They
7937 must always be lowercased; and the strings pointed to shouldn't
7938 be modified (you must copy them to modify them). Fix a few bugs
7939 related to this. [Dean Gaudet]
7941 *) API: Clarification: except for RAW_ARGS, all command handlers can
7942 treat the char * parameters as permanent, and modifiable. There
7943 is no need to pstrdup() them. Clean up some needless pstrdup().
7946 *) Now mod_so keeps track of which module shared objects with which names
7947 are loaded and thus avoids multiple loading and unloading and irritating
7948 error_log messages. [Ralf S. Engelschall]
7950 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
7951 environment variable in the apache core. But that tweaking interferes
7952 with mod_setenv. So don't tweak if the user has specified an explicit
7953 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
7955 *) rputs() did not calculate r->sent_bodyct properly.
7956 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
7958 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
7959 name, or left unset if this value is unavailable. Apache was setting
7960 it to the IP address when unavailable.
7961 [Tony Finch <fanf@demon.net>] PR#1925
7963 *) Various improvements to the configuration and build support for compiling
7964 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
7965 OSF1 support with GCC and vendor compilers was added. This way shared
7966 object support is now provided out-of-the-box for FreeBSD, Linux,
7967 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
7968 [Ralf S. Engelschall]
7970 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
7971 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
7972 and USE_OS2_SCOREBOARD. [Dean Gaudet]
7974 *) Fix one more special locking problem for RewriteMap programs in
7975 mod_rewrite: According to the documentation of flock(), "Locks are on
7976 files, not file descriptors. That is, file descriptors duplicated
7977 through dup(2) or fork(2) do not result in multiple instances of a lock,
7978 but rather multiple references to a single lock. If a process holding a
7979 lock on a file forks and the child explicitly unlocks the file, the
7980 parent will lose its lock.". To overcome this we have to make sure the
7981 RewriteLock file is opened _AFTER_ the childs were spawned which is now
7982 the case by opening it in the child_init instead of the module_init API
7983 hook. [Ralf S. Engelschall] PR#1029
7985 *) Change to Location and LocationMatch semantics. LocationMatch no
7986 longer lets a single slash match multiple adjacent slashes in the
7987 URL. This change is for consistency with RewriteRule and
7988 AliasMatch. Multiple slashes have meaning in URLs that they do
7989 not have in (some) filesystems. Location on the other hand can
7990 be considered a shorthand for a more complicated regex, and it
7991 does match multiple slashes with a single slash -- which is
7992 also consistent with the Alias directive.
7993 [Dean Gaudet] related PR#1440
7995 *) Fix bug with mod_mime_magic causing certain files, including files
7996 of length 0, to result in no response from the server.
7999 *) The Configure script now generates src/include/ap_config.h which
8000 contains the set of defines used when Apache is compiled on a platform.
8001 This file can then be included by external modules before including
8002 any Apache header files in case they are being built separately from
8003 Apache. Along with this change, a couple of minor changes were
8004 made to make Apache's #defines coexist peacefully with any autoconf
8005 defines an external module might have. [Rasmus Lerdorf]
8007 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
8008 but without any RewriteXXXXX directives. Here mod_rewrite is given no
8009 chance by the API to initialize its per-server configuration and thus
8010 receives the wrong one from the main server. This is now avoided by
8011 remembering the server together with the config structure while
8012 configuring and later assuming there is no config when we see a
8013 difference between the remembered server and the one calling us.
8014 [Ralf S. Engelschall] PR#1790
8016 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
8017 is automatically disabled under configure time when the dbm_xxx functions
8018 are not available. Second, two heavy source code errors in the DBM
8019 support code were fixed. This makes DBM RewriteMap's usable again after
8020 a long time of brokenness. [Ralf S. Engelschall] PR#1696
8022 *) Now all configuration files support Unix-style line-continuation via
8023 the trailing backslash ("\") character. This enables us to write down
8024 complex or just very long directives in a more readable way. The
8025 backslash character has to be really the last character before the
8026 newline and it has not been prefixed by another (escaping) backslash.

8038 *) WIN32: Preserve trailing slash in canonical path (and hence
8039 in PATH_INFO). [Paul Sutton, Ben Laurie]
8041 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
8042 depending on the rev of Solaris and what mixture of modules
8043 are in use. So it has been disabled, and Solaris is back to
8044 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
8045 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
8046 up static content only servers. Or it may fail unpredictably.

8049 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
8052 *) API: Rewrite of absoluteURI handling, and in particular how
8053 absoluteURIs match vhosts. Unless a request is a proxy request, a
8054 "http://host" url is treated as if a similar "Host:" header had been
8055 supplied. This change was made to support future HTTP/1.x protocols
8056 which may require clients to send absoluteURIs for all requests.
8058 In order to achieve this change subtle changes were made to the API. In a
8059 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
8060 that the unmodified uri can be retrieved easily. r->proxyreq is not set
8061 by the core, modules must set it during the post_read_request or
8062 translate_names phase.
8064 Plus changes to the virtualhost test suite for absoluteURI testing.
8066 This fixes several bugs with the proxy proxying requests to vhosts
8067 managed by the same httpd.
8070 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
8071 code from mod_rewrite. The vhost matching is now performed by a
8072 globally available function matches_request_vhost(). [Dean Gaudet]
8074 *) Reduce memory usage, and speed up ServerAlias support. As a

8088 *) API: A new source module main/util_uri.c; It contains a routine
8089 parse_uri_components() and friends which breaks a URI into its component
8090 parts. These parts are stored in a uri_components structure called
8091 parsed_uri within each request_rec, and are available to all modules.
8092 Additionally, an unparse routine is supplied which re-assembles the URI
8093 components back to an URI, optionally hiding the username:password@ part
8094 from ftp proxy requests, and other useful routines. Within the structure,
8095 you find on a ready-for-use basis:

8101 port_str; /* port string (integer representation is in "port") */
8102 path; /* the request path (or "/" if only scheme://host was given) */
8103 query; /* Everything after a '?' in the path, if present */
8104 fragment; /* Trailing "#fragment" string, if present */
8105 This is meant to serve as the platform for *BIG* savings in
8106 code complexity for the proxy module (and maybe the vhost logic).
8109 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
8110 ${map:key}) available for all location where a string is created in
8111 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
8112 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
8113 possible expansions are consequently usable at all string creation
8114 locations. [Ralf S. Engelschall]
8116 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
8117 and not 1) and the per-virtual-server merging of directives. Now all
8118 directives except `RewriteEngine' and `RewriteOption' are either
8119 completely overridden (default) or completely inherited (when
8120 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
8122 *) Fix `RewriteMap' program lookup in situations where such maps are
8123 defined but disabled (`RewriteEngine off') in per-server context.
8124 [Ralf S. Engelschall] PR#1431
8126 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
8127 server to bind to port 0 rather than 80. [Dean Gaudet]
8129 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
8130 (like SunOS and FreeBSD) which don't accept the locking of pipes
8131 directly. A new directive RewriteLock is introduced which can be used to
8132 setup a separate locking file which then is used for synchronization.
8133 [Ralf S. Engelschall] PR#1029
8135 *) WIN32: The server root is obtained from the registry key
8136 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
8137 "1.3 beta"), unless overridden by the -d command line flag. The
8138 value is stored by running "apache -i -d serverroot". [Paul Sutton]
8140 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
8141 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]
8143 *) Now mod_rewrite no longer makes problematic assumptions on the characters
8144 a username can contain when trying to expand it via /etc/passwd.
8145 [Ralf S. Engelschall]
8147 *) The mod_setenvif BrowserMatch backwards compatibility command did not
8148 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
8150 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
8151 type but with a special post-processing for the looked-up value: It
8152 parses it into alternatives according to `|' chars and then only one
8153 particular alternative is chosen randomly (this is an essential
8154 functionality needed for balancing between backend-servers when using
8155 Apache as a Reverse Proxy. The looked up value here is a list of
8156 servers). Second, `int' with the built-in maps named `tolower' and
8157 `toupper' which can be used to map URL parts to a fixed case (this is an
8158 essential feature to fix the case of server names when doing mass
8159 virtual-hosting with the help of mod_rewrite instead of using
8160 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
8161 Jay Soffian <jay@cimedia.com>] PR#1631
8163 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
8164 This directive lets Apache adjust the URL in Location-headers on HTTP
8165 redirect responses sent by the remote server. This way the virtually
8166 mapped area is no longer left on redirects and thus by-passed which is
8167 especially essential when running Apache as a reverse proxy.
8168 [Ralf S. Engelschall]
8170 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
8171 hidden. [Alvaro Martinez Echevarria]
8173 *) Apache will, when started with the -X (single process) debugging flag,
8174 honor the SIGINT or SIGQUIT signals again now. This capability got lost
8175 a while ago during OS/2 signal handling changes.
8177 *) [PORT] Work around the fact that NeXT runs on more than the
8178 m68k chips in mod_status [Scott Anguish and Timothy Luoma
8181 *) [PORT] Recognize FreeBSD versions so we can use the OS regex as well
8182 as handling unsigned-chars for FreeBSD v3 and v2 [Andrey Chernov
8183 <ache@nagual.pp.ru> and Jim] PR#1450
8185 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
8186 In particular the handlers could trigger themselves into an infinite
8187 loop if RLimitMem was used with a small amount of memory -- too small
8188 for the signal stack frame to be set up. [Dean Gaudet]

8199 *) API: As Ken suggested the check_cmd_context() function and related
8200 defines are non-static now so modules can use 'em. [Martin Kraemer]
8202 *) mod_info would occasionally produce an unpaired <tt> in its
8203 output. Fixed. [Martin Kraemer]
8205 *) By default AIX binds a process (and it's children) to a single
8206 processor. httpd children now unbind themselves from that cpu
8207 and re-bind to one selected at random via bindprocessor()
8210 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
8211 effect. Work around it by using RLIMIT_AS for the RLimitMEM
8212 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
8214 *) mod_mime_magic error message should indicate the filename when
8215 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
8217 *) Previously Apache would permit </Files> to end <FilesMatch> (and
8218 similary for Location and Directory), now this is diagnosed as an
8219 error. Improve error messages for mismatched sections (<Files>,
8220 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
8221 [Dean Gaudet, Martin Kraemer]
8223 *) <Files> is not permitted within <Location> (because of the
8224 semantic ordering). [Dean Gaudet] PR#379
8226 *) <Files> with wildcards was broken by the change in wildcard
8227 semantics (* does not match /). To fix this, <Files> now
8228 apply only to the basename of the request filename. This
8229 fixes some other inconsistencies in <Files> semantics
8230 (such as <Files a*b> not working). [Dean Gaudet] PR#1817
8232 *) Removed bogus "dist.tar" target from Makefile.tmpl and make sure
8233 backup files are removed on "clean" target [Ralf S. Engelschall]
8235 *) PORT: Add -lm to LIBS for HPUX. [Dean Gaudet] PR#1639
8237 *) Various errors from select() and accept() in child_main() would
8238 result in an infinite loop. It seems these two tickle kernel
8239 or library bugs occasionally, and result in log spammage and
8240 a generally bad scene. Now the child exits immediately,
8241 which seems to be a good workaround.

8244 *) Cleaned up some race conditions in unix child_main during
8245 initialization. [Dean Gaudet]
8247 *) SECURITY: "UserDir /abspath" without a * in the path would allow
8248 remote users to access "/~.." and bypass access restrictions
8249 (but note /~../.. was handled properly).

8252 *) API: os_is_path_absolute() now takes a const char * instead of a char *.
8255 Changes with Apache 1.3b5
8257 *) Source file dependencies in Makefile.tmpl files throughout the
8258 source tree were updated to accurately reflect reality.
8261 *) Preserve the content encoding given by the AddEncoding directive
8262 when the client doesn't otherwise specify an encoding.
8263 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>]
8265 *) Sort out problems with canonical filename handling happening too late.
8266 [Dean Gaudet, Ben Laurie]
8268 Changes with Apache 1.3b4
8270 *) The module structure was modified to include a *dynamic_load_handle
8271 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
8272 has been bumped accordingly. [Paul Sutton]
8274 *) All BrowserMatch directives mentioned in
8275 htdocs/manual/known_client_problems.html are in the default
8276 configuration files. [Lars Eilebrecht]
8278 *) MiNT port update. [Jan Paul Schmidt]
8280 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
8281 equivalent, similarly for x-compress and compress. Apache
8282 now ignores a leading x- when comparing encodings. It also
8283 preserves the encoding the client requests (for example if
8284 it requests x-gzip, then Apache will respond with x-gzip
8285 in the Content-Encoding header).
8286 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
8288 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
8290 *) Added mod_so module to support dynamic loading of modules on Unix
8291 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
8292 instead of AddModule in Configuration to build shared modules
8293 [Sameer Parekh, Paul Sutton]
8295 *) Minor cleanups to r->finfo handling in some modules.
8298 *) Abstract read()/write() to ap_read()/ap_write().
8299 Makes it easier to add other types of IO code such as SFIO.
8302 *) API: Generalize default_port manipulations to make support of
8303 different protocols easier. [Ben Laurie, Randy Terbush]
8305 *) There are many cases where users do not want Apache to form
8306 self-referential urls using the "canonical" ServerName and Port.
8307 The new UseCanonicalName directive (default on), if set to off
8308 will cause Apache to use the client-supplied hostname and port.
8309 API: Part of this change required a change to the construct_url()
8310 prototype; and the addition of get_server_name() and
8312 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
8313 PR#315, 459, 485, 1433
8315 *) Yet another rearrangement of the source tree.. now all the common
8316 header files are in the src/include directory. The -Imain -Iap
8317 references in Makefiles have been changed to the simpler -Iinclude
8318 instead. In addition to simplifying the build a little bit, this
8319 also makes it clear when a module is referencing something in a
8320 other than kosher manner (e.g., the proxy including mod_mime.h).
8321 Module-private header files (the proxy, mod_mime, the regex library,
8322 and mod_rewrite) have not been moved to src/include; nor have
8323 the OS-abstraction files. [Ken Coar]
8325 *) Fix a bug where r->hostname didn't have the :port stripped
8326 from it. [Dean Gaudet]
8328 *) Tweaked the headers_out table size, and the subprocess_env
8329 table size guess in rename_original_environment(). Added
8330 MAKE_TABLE_PROFILE which can help discover make_table()
8331 calls that use too small an initial guess, see alloc.c.
8334 *) Options and AllowOverride weren't properly merging in the main
8335 server setting inside vhosts (only an issue when you have no
8336 <Directory> or other section containing an Options that affects
8337 a request). Options +foo or -foo in the main_server wouldn't
8338 affect the main_server's lookup defaults. [Dean Gaudet]
8340 *) Variable 'cwd' was being used pointlessly before being set.
8343 *) r->allowed handling cleaned up in the standard modules.
8346 *) Some case-sensitivity issues cleaned up to be consistent with
8347 RFC2068. [Dean Gaudet]
8349 *) SIGURG doesn't exist everywhere.
8350 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8352 *) mod_unique_id was erroneously generating a second unique id when
8353 an internal redirect occured. Such redirects occur, for example,
8354 when processing a DirectoryIndex match. [Dean Gaudet]
8356 *) API: table_add, table_merge, and table_set include implicit pstrdup()
8357 of the key and value. But in many cases this is not required
8358 because the key/value is a constant, or the value has been built
8359 by pstrcat() or other similar means. New routines table_addn,
8360 table_mergen, and table_setn have been added to the API, these
8361 routines do not pstrdup() their arguments. The core code and
8362 standard modules were changed to take advantage of these routines.
8363 The resulting server is up to 20% faster in some situations.
8365 Note that it is easy to get code subtly wrong if you pass a key/value
8366 which is in a pool other than the pool of the table. The only
8367 safe thing to do is to pass key/values which are in the pool of
8368 the table, or in one of the ancestors of the pool of the table.
8369 i.e. if the table is part of a subrequest, a value from the main
8370 request's pool is OK since the subrequest pool is a sub_pool of the
8371 main request's pool (and therefore has a lifespan at most as long as
8372 the main pool). There is debugging code which can detect improper
8373 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
8374 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
8376 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
8377 which don't exist on disk more gracefully; handles vhosts properly.
8378 Update documentation to reflect the code -- if there's no
8379 MimeMagicFile directive then the module is not enabled.
8382 *) PORT: Some older *nix dialects cannot automatically start scripts
8383 which begin with a #! interpreter line (the shell starts the scripts
8384 appropriately on these platforms). Apache now supports starting of
8385 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
8386 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
8389 *) API: "typedef array_header table" removed from alloc.h, folks should
8390 have been writing to use table as if it were an opaque type, but even
8391 some standard modules got this wrong. By changing the definition
8392 to "typedef struct table table" module authors will receive compile
8393 time warnings that they're doing the wrong thing. This change
8394 facilitates future changes with more sophisticated table
8395 structures. Specifically, module authors should be using table_elts()
8396 to get access to an array_header * for the table. [Dean Gaudet]
8398 *) API: Renamed new_connection() to avoid namespace collision with LDAP
8399 library routines. [Ken Coar, Rasmus Lerdorf]
8401 *) WIN32: mod_speling is now available on the Win32 platform.
8404 *) For clarity the following compile time definition was changed:
8406 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
8408 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
8409 and not be a general notice that the OS has mmap(). Now the
8410 HAVE_MMAP/SHMGET #defines strictly are informational that the
8411 OS has that method of shared memory; the type to use for
8412 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
8413 and USE_SHMGET_SCOREBOARD). This allows outside modules to
8414 determine if shared memory is available and allows Apache
8415 to determine the best method to use for the scoreboard.
8418 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
8419 as do various earlier versions. It should be safe on all versions.
8420 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
8421 the slack code. A few other cleanups for Unixware.

8424 *) PORT: A/UX can handle single-listen accepts without mutex
8425 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
8427 *) When die() happens we need to eat any request body if one exists.
8428 Otherwise we can't continue with a keepalive session. This shows up
8429 as a POST problem with MSIE 4.0, typically against pages which are
8430 authenticated. [Roy Fielding] PR#1399
8432 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
8433 header will be passed to CGIs. This is generally a security hole, so
8434 it's not a default. [Marc Slemko] PR#549
8436 *) Fix Y2K problem with date printing in suexec log.

8439 *) WIN32 deserves a pid file. [Ben Hyde]
8441 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
8443 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
8444 The choice of flock vs. fcntl was made based on timings which showed that
8445 even on non-NFS, non-exported filesystems fcntl() was an order of
8446 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
8447 that single socket users will see no difference. [Dean Gaudet] PR#467
8449 *) "File does not exist" error message was erroneously including the
8450 errno. [Marc Slemko]
8452 *) Improve the warning message generated when a client drops the
8453 connection (hits stop button, etc.) during a send. [Roy Fielding]
8455 *) Defining GPROF will disable profiling in the parent and enable it
8456 in the children. If you're profiling under Linux this is pretty much
8457 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
8459 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
8462 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
8463 gcc functionality. Work around it.

8466 *) Some linkers complain when .o files contain no functions.
8467 [Keith Severson <keith@sssd.navy.mil>] PR#1614
8469 *) Some const declarations in mod_imap.c that were added for debugging
8470 purposes caused some compilers heartburn without adding any
8471 significant value, so they've been removed. [Ken Coar]
8473 *) The src/main/*.h header files have had #ifndef wrappers added to
8474 insulate them against duplicate calls if they get included through
8475 multiple paths (e.g., in .c files as well as other .h files).
8478 *) The libap routines now have a header file for their prototypes,
8479 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
8481 *) mod_autoindex with a plaintext header file would emit the <PRE>
8482 start-tag before the HTML preamble, rather than after the preamble
8483 but before the header file contents. [John Van Essen <jve@gamers.org>]
8486 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8487 only an issue on systems without a MAXDNAME define or where
8488 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8490 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8491 is used to read various types of files such as htaccess and
8492 htpasswd files. [Marc Slemko]
8494 *) SECURITY: Ensure that the buffer returned by ht_time is always
8495 properly null terminated. [Marc Slemko]
8497 *) The "Connection" header could be sent back with multiple "close"
8498 tokens. Not an error, but a waste.
8499 [Ronald.Tschalaer@psi.ch] PR#1683
8501 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
8502 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
8504 *) "basic" auth needs a case-insensitive comparison.
8505 [Ronald.Tschalaer@psi.ch] PR#1666
8507 *) For maximum portability, the environment passed to CGIs should
8508 only contain variables whose names match the regex
8509 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
8510 underscores over any character outside the regex. This
8511 affects HTTP_* variables, in a way that should be backward
8512 compatible for all the standard headers; and affects variables
8513 set with SetEnv/BrowserMatch and similar directives.
8516 *) mod_speling returned incorrect HREF's when an ambigous match

8524 *) PORT: Fix problem killing children when terminating. Allow ^C

8552 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8553 including fixing a possible buffer overflow. [Dean Gaudet]
8555 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
8556 (connections are not dropped). Code can handle graceful restarts
8557 (but there is as yet no way to signal this to Apache). Various
8558 other cleanups. [Paul Sutton]
8560 *) The aplog_error changes specific to 1.3 introduced a buffer
8561 overrun in the (now legacy) log_printf function. Fixed.
8564 *) mod_digest didn't properly deal with proxy authentication. It
8565 also lacked a case-insensitive comparision of the "Digest"

8597 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
8599 *) send_fd_length() did not calculate total_bytes_sent properly.
8600 [Ben Reser <breser@regnow.com>] PR#1366
8602 *) The bputc() macro was not properly integrated with the chunking
8603 code; in many cases modules using bputc() could cause completely
8604 bogus chunked output. (Typically this will show up as problems
8605 with Internet Explorer 4.0 reading a page, but other browsers
8606 having no problem.) [Dean Gaudet]
8608 *) Create LARGE_WRITE_THRESHOLD define which determines how many
8609 bytes have to be supplied to bwrite() before it will consider
8610 doing a writev() to assemble multiple buffers in one system
8611 call. This is critical for modules such as mod_include,
8612 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
8613 strings in some cases. The result would be extra effort
8614 setting up writev(), and in many cases extra effort building

8622 *) WIN32: Check for binaries by looking for the executable header
8623 instead of counting control characters.
8624 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
8626 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
8627 so the functionality is available to applications other than the
8628 server itself (like the src/support tools). [Ken Coar]
8630 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
8631 the libap consolidation work. [Ken Coar]
8633 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
8634 useful, and isn't what the standards require. Now it returns 0

8706 The problem was that certain undocumented environment variables
8707 needed for sockets to work under Win32 were not being passed.

8710 *) Add a "-V" command line flag to the httpd binary. This
8711 flag shows some of the defines that Apache was compiled with.
8712 It is useful for debugging purposes. [Martin Kraemer]

8722 on all platforms. [Marc Slemko] PR#1214
8724 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
8725 This turns out to be a bug in Winsock - select() doesn't always
8726 return the correct status. [Ben Laurie]
8728 *) Directives owned by http_core can now use the new check_cmd_context()
8729 routine to ensure that they're not being used within a container
8730 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
8732 *) PORT: Recent changes made it necessary to add explicit prototype
8733 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
8735 *) It was necessary to distinguish between resources which are
8736 allocated in the parent, for cleanup in the parent, and resources
8737 which are allocated in each child, for cleanup in each child.
8738 A new pool was created which is passed to the module child_init
8739 and child_exit functions; modules are free to register per-child
8740 cleanups there. This fixes a bug with reliable piped logs.
8743 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
8744 unless it was also doing FancyIndexes, but it displayed the
8745 HeaderName file at the top under all circumstances. It now shows
8746 the ReadmeName file for simple indices, too, as it should.
8749 *) http_core was mmap()ing even in cases where it wasn't going to
8750 read the file. [Ben Hyde <bhyde@gensym.com>]
8752 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
8753 Now the rewriting engine (the heart of mod_rewrite) is organized more
8754 straight-forward, first time well documented and reduced to the really
8755 essential parts. All redundant cases were stripped off and processing now
8756 is the same for both per-server and per-directory context with only a
8757 minimum difference (the prefix stripping in per-dir context). As a
8758 side-effect some subtle restrictions and two recently discovered problems
8759 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
8760 context and restrictions on the substitution URL on redirects.
8761 Additionally some minor source cleanups were done.

8916 Changes with Apache 1.3b2 (there is no 1.3b1)
8918 *) TestCompile was not passing $LIBS [Dean Gaudet]
8920 *) Makefile.tmpl was not using $CFLAGS in the link phase.
8923 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
8924 rudimentary memory debugger which can be used on live servers with
8925 low impact -- it sets all allocated and freed memory bytes to 0xa5.
8926 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
8927 and free() for each object. This is far more expensive and should
8928 only be used for testing with tools such as Electric Fence and
8929 Purify. See main/alloc.c for more details. [Dean Gaudet]
8931 *) Configure uses a sh trap and didn't set its exitcode properly.
8932 [Dean Gaudet] PR#1159
8934 *) Yet another vhost revamp. Add the NameVirtualHost directive which
8935 explicitly lists the ip:port pairs that are to be used for name-vhosts.
8936 From a given ip:port, regardless what the Host: header is, you can
8937 only reach the vhosts defined on that ip:port. The precedence of
8938 vhosts was reversed to match other precedences in the config --
8939 the earlier vhosts override the later vhosts. All vhost matching was
8940 moved into http_vhost.[ch]. [Dean Gaudet]
8942 *) ap_inline can be used to force inlining. GNUC __attribute__() can
8943 be used for whatever reason is appropriate (i.e. format() warnings
8944 for printf style functions). Both are enabled only with
8945 gcc >= 2.7.x (so that we have fewer support issues with older
8946 versions). [Dean Gaudet]
8948 *) Fix support for Proxy Authentication (we were testing the response
8949 status too early). [Marc Slemko]
8951 *) CoreDumpDirectory directive directs where the core file is
8952 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are

8956 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
8958 *) When booting, apache will now detach itself from stdin, stdout,
8959 and stderr. stderr will not be detached until after the config
8960 files have been read so you will be able to see initial error
8961 messages. After that all errors are logged in the error_log.
8962 This makes it more convenient to start apache via rsh, ssh,
8963 or crontabs. [Dean Gaudet] PR#523
8965 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8966 Also removed the auto-generated link to www.apache.org that was the
8967 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8969 *) send_fb would not detect aborted connections in some situations.
8972 *) mod_include would use uninitialized data when parsing certain
8973 expressions involving && and ||. [Brian Slesinsky] PR#1139
8975 *) mod_imap should only handle GET methods. [Jay Bloodworth]
8977 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8979 *) mod_autoindex improperly counted &escapes; as more than one
8980 character in the description. It also improperly truncated
8981 descriptions that were exactly the maximum length.
8984 *) RedirectMatch was not properly escaping the result (PR#1155). Also
8985 "RedirectMatch /advertiser/(.*) $1" is now permitted.
8988 *) mod_include now uses symbolic names to check for request success
8989 and return HTTP errors, and correctly handles all types of
8990 redirections (previously it only did temporary redirect correctly).
8991 [Ken Coar, Roy Fielding]
8993 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8994 r->filename. Since those two are meant to be in sync with each other

9007 *) Fixed error in proxy_util.c when looping through multiple host IP
9008 addresses. [Lars Eilebrecht] PR#974
9010 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
9011 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
9012 bytes before writing, but it will never split a log entry across a
9013 buffer boundary. [Dean Gaudet]
9015 *) API: the short_score record has been split into two pieces, one which
9016 the parent writes on, and one which the child writes on. As part of
9017 this change the get_scoreboard_info() function was removed, and
9018 scoreboard_image was exported. This change fixes a race condition
9019 in file based scoreboard systems, and speeds up changes involving the
9020 scoreboard in earlier 1.3 development. [Dean Gaudet]
9022 *) API: New register_other_child() API (see http_main.h) which allows
9023 modules to register children with the parent for maintenance. It
9024 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
9026 *) API: New piped_log API (see http_log.h) which implements piped logs,
9027 and will use register_other_child to implement reliable piped logs
9028 when it is available. The reliable piped logs part can be disabled
9029 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
9030 logs is only available on Unix. [Dean Gaudet]
9032 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
9033 meets_conditions(). This allows conditional HTTP selection to be
9034 handled separately from the storing of the header fields, and provides
9035 the ability for CGIs to set their own ETags for conditional checking.
9036 [Ken Coar, Roy Fielding] PR#895
9038 *) Changes to mod_log_config to allow naming of format strings.
9039 Format nicknames are defined with "LogFormat fmt nickname", and can

9043 *) New module, "mod_speling", which can help find files even when
9044 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
9046 *) API: New function child_terminate() triggers the child process to
9047 exit, while allowing the child finish what it needs to for the
9048 current request first.
9049 [Doug MacEachern, Alexei Kosut]
9051 *) Windows now defaults to using full status reports with mod_status.
9052 [Alexei Kosut] PR #1094
9054 *) *Really* disable all mod_rewrite operations if the engine is off.
9055 Some things (like RewriteMaps) were checked/performed even if they
9056 weren't supposed to be. [Ken Coar] PR #991
9058 *) Implement a new timer scheme which eliminates the need to call alarm() all
9059 the time. Instead a counter in the scoreboard for each child is used to
9060 show when the child has made forward progress. The parent samples this
9061 counter every scoreboard maintenance cycle, and issues SIGALRM if no
9062 progress has been made in the timeout period. This reduces the static
9063 request best-case syscall count to 22 from 29. This scheme is only
9064 used by systems with memory-based scoreboards. [Dean Gaudet]
9066 *) The proxy now properly handles CONNECT requests which are sent
9067 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
9069 *) A script called apachectl has been added to the support
9070 directory. This script allows you to do things such as
9071 "apachectl start" and "apachectl restart" from the command
9074 *) Modules and core routines are now put into libraries, which
9075 simplifies the link line tremendously (among other advantages).
9078 *) Some of the MD5 names defined in Apache have been renamed to have
9079 an `ap_' prefix to avoid conflicts with routines supplied by
9080 external libraries. [Ken Coar]
9082 *) Removal of mod_auth_msql.c from the distribution. There are many
9083 other options for databases today. Rather than offer one option,
9084 offer none at this time. mod_auth_msql and other SQL database
9085 authentication modules can be found at the Apache Module Registry.
9086 http://modules.apache.org/ It would be nice to offer a generic
9087 mod_auth_sql option in the near future.
9089 *) PORT: BeOS support added [Alexei Kosut]
9091 *) Configure no longer accepts the -make option, since it creates
9092 Makefile on the fly based on Makefile.tmpl and Configuration.
9094 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
9095 of forcibly killing off all its processes and exiting without
9096 cleaning up. [Alexei Kosut]
9098 *) API: A new field in the request_rec, r->mtime, has been added to
9099 avoid gratuitous parsing of date strings. It is intended to hold
9100 the last-modified date of the resource (if applicable). An
9101 update_mtime() routine has also been added to advance it if
9102 appropriate. [Roy Fielding, Ken Coar]
9104 *) SECURITY: If a htaccess file can not be read due to bad permissions,
9105 deny access to the directory with a HTTP_FORBIDDEN. The previous
9106 behavior was to ignore the htaccess file if it could not be read.
9107 This change may make some setups with unreadable htaccess files
9108 stop working. [Marc Slemko] PR#817
9110 *) Add aplog_error() providing a mechanism to define levels of
9111 verbosity to the server error logging. This addition also provides
9112 the ability to log errors using syslogd. Error logging is configurable
9113 on a per-server basis using the LogLevel directive. Conversion
9114 of log_*() in progress. [Randy Terbush]
9116 *) Further enhance aplog_error() to not log filename, line number, and
9117 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
9119 *) WIN32: Canonicalise filenames under Win32. Short filenames are
9120 converted to long ones. Backslashes are converted to forward
9121 slashes. Case is converted to lower. Parts of URLs that do not
9122 correspond to files are left completely alone. [Ben Laurie]

9135 This fixes things such as the logging of headers sent from
9136 the proxy. [Marc Slemko] PR#659
9138 *) support/httpd_monitor is no longer distributed because the
9139 scoreboard should not be file based if at all possible. Use
9140 mod_status to see current server snapshot.
9142 *) (set_file_slot): New function, allowing auth directives to be
9143 independent of the server root, so the server documents can be
9144 moved to a different directory or machine more easily.
9145 [David J. MacKenzie]
9147 *) If no TransferLog is given explicitly, decline
9148 to log. This supports coexistence with other logging modules,
9149 such as the custom one that UUNET uses. [David J. MacKenzie]
9151 *) Check for titles in server-parsed HTML files.
9152 Ignore leading newlines and returns in titles. The old behavior
9153 of replacing a newline after <title> with a space causes the
9154 title to be misaligned in the listing. [David J. MacKenzie]
9156 *) Change mod_cern_meta to be configurable on a per-directory basis.
9157 [David J. MacKenzie]
9159 *) Add 'Include' directive to allow inclusion of configuration
9160 files within configuration files. [Randy Terbush]
9162 *) Proxy errors on connect() are logged to the error_log (nothing
9163 new); now they include the IP address and port that failed
9164 (*that's* new). [Ken Coar, Marc Slemko] PR#352
9166 *) Various architectures now define USE_MMAP_FILES which causes
9167 the server to use mmap() for static files. There are two
9168 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
9169 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
9170 number of bytes written in one cycle from a single mmap()d object,
9171 default 32768). [Dean Gaudet]
9173 *) API: Added post_read_request API phase which is run right after reading
9174 the request from a client, or right after an internal redirect. It is
9175 useful for modules setting environment variables that depend only on
9176 the headers/contents of the request. It does not run during subrequests
9177 because subrequests inherit pretty much everything from the main
9178 request. [Dean Gaudet]
9180 *) Added mod_unique_id which is used to generate a unique identifier for
9181 each hit, available in the environment variable UNIQUE_ID.
9184 *) init_modules is now called after the error logs have been opened. This
9185 allows modules to emit information messages into the error logs.
9188 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9189 information for case where proxy module is not available. [Marc Slemko]
9191 *) PORT: Apache has need for mutexes to serialize its children around
9192 accept. In prior versions either fcntl file locking or flock file
9193 locking were used. The method is chosen by the definition of
9194 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
9195 and FLOCK for flock(). New options have been added:
9196 - SYSVSEM to use System V style semaphores
9197 - PTHREAD to use POSIX threads (appears to work on Solaris only)
9198 - USLOCK to use IRIX uslock
9199 Based on timing various techniques, the following changes were made
9201 - Linux 2.x uses flock instead of fcntl
9202 - Solaris 2.x uses pthreads
9203 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
9204 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
9205 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
9206 Martijn Koster <m.koster@pobox.com>]
9208 *) PORT: The semantics of accept/select make it very desirable to use
9209 mutexes to serialize accept when multiple Listens are in use. But
9210 in the case where only a single socket is open it is sometimes
9211 redundant to serialize accept(). Not all unixes do a good job with
9212 potentially dozens of children blocked on accept() on the same
9213 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
9214 the server will avoid serialization when listening on only one socket,
9215 and use serialization when listening on multiple sockets.
9216 [Dean Gaudet] PR#467
9218 *) Configure changes: TestLib replaced by TestCompile, which has
9219 some additional capability (such as doing a sanity check of
9220 the compiler and flags selected); the version of Solaris is now
9221 available via the #define value of SOLARIS2; IRIX n32bit libs
9222 now supported and selectable by new Configuration Rule: IRIXN32;
9223 We no longer default to -O2 optimization. [Jim Jagielski]
9225 *) Updated Configure: Configuration now uses AddModule to specify
9226 module source or binary file location, relative to src directory.
9227 Modules can be dropped into modules/extra, or in their own
9228 directory, and modules can come with a Makefile or Configure can
9229 create one. Modules can add compiler or library information to
9230 generated Makefiles. [Paul Sutton]
9232 *) Source core re-organisation: distributed modules are now in
9233 modules/standard. All other source code is in main. OS-specific
9234 code is in os/{unix,emx,win32} directories. [Paul Sutton]
9236 *) mod_browser has been removed, since it's replaced by mod_setenvif.
9239 *) Fix another long-standing bug in sub_req_lookup_file where it would
9240 happily skip past access checks on subdirectories looked up with
9241 relative paths. (It's used by mod_dir, mod_negotiation,
9242 and mod_include.) [Dean Gaudet]
9244 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
9245 N is the number of <Directory> sections, and M is the number of
9246 components in the filename of an object.
9248 To achieve this optimization the following config changes were made:
9249 - Wildcards (* and ?, not the regex forms) in <Directory>s,
9250 <Files>s, and <Location>s now treat a slash as a special
9251 character. For example "/home/*/public_html" previously would
9252 match "/home/a/andrew/public_html", now it only matches things
9253 like "/home/bob/public_html". This mimics /bin/sh behaviour.
9254 - It's possible now to use [] wildcarding in <Directory>, <Files>
9256 - Regex <Directory>s are applied after all non-regex <Directory>s.
9260 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
9261 and corrupted paths. [Dean Gaudet]
9263 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
9264 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
9265 be accessed now via backreferences $1..$9 in RewriteConds test-against
9266 strings in addition to RewriteRules subst string. Second the grouped
9267 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
9268 via backreferences %1..%9 both in following RewriteCond test-against
9269 strings and RewriteRules subst string. This provides maximum flexibility
9270 through the use of backreferences.
9271 Additionally the rewriting engine was cleaned up by putting common
9272 code to the new expand_backrefs_inbuffer() function.
9273 [Ralf S. Engelschall]
9275 *) When merging the main server's <Directory> and <Location> sections into
9276 a vhost, put the main server's first and the vhost's second. Otherwise
9277 the vhost can't override the main server. [Dean Gaudet] PR#717
9279 *) The <Directory> code would merge and re-merge the same section after
9280 a match was found, possibly causing problems with some modules.
9283 *) ip-based vhosts are stored and queried using a hashing function, which
9284 has been shown to improve performance on servers with many ip-vhosts.
9285 Some other changes had to be made to accommodate this:
9286 - the * address for vhosts now behaves like _default_
9287 - the matching process now is:
9288 - match an ip-vhost directly via hash (possibly matches main
9290 - if that fails, just pretend it matched the main server
9291 - if so far only the main server has been matched, perform
9292 name-based lookups (ServerName, ServerAlias, ServerPath)
9293 *only on name-based vhosts*
9294 - if they fail, look for _default_ vhosts
9295 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
9297 *) dbmmanage overhaul:
9298 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
9299 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
9300 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
9301 - provide better seed for rand
9302 - prompt for password as per getpass(3) (turn off echo, read from
9304 - use "newstyle" crypt based on $Config{osname} ($^O)
9305 - will not add a user if already in database, use new `update' command
9307 - added `check' command to check a users' password
9308 - added `import' command to convert existing password text-files or
9309 dbm files exported with `view'
9310 - more descriptive usage, general cleanup, 'use strict' clean, etc.
9313 *) Added psocket() which is a pool form of socket(), various places within
9314 the proxy weren't properly blocking alarms while registering the cleanup
9315 for its sockets. bclose() now uses pclose() and pclosesocket(). There
9316 was a bug where the client socket was being close()d twice due a still
9317 registered cleanup. [Dean Gaudet]
9319 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
9322 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
9323 [Jason Venner <jason@idiom.com>] PR#667
9325 *) Enable ``=""'' for RewriteCond directives to match against
9326 the empty string. This is the preferred way instead of ``^$''.
9327 [Ralf S. Engelschall]
9329 *) Fixed an infinite loop in mod_imap for references above the server root
9330 [Dean Gaudet] PR#748
9332 *) mod_proxy now has a ReceiveBufferSize directive, similar to
9333 SendBufferSize, so that the TCP window can be set appropriately
9334 for LFNs. [Phillip A. Prindeville]
9336 *) mod_browser has been replaced by the more general mod_setenvif
9337 (courtesy of Paul Sutton). BrowserMatch* directives are still
9338 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
9339 UnSetEnvIfZero directives. [Ken Coar]
9341 *) "HostnameLookups double" forces double-reverse DNS to succeed in
9342 order for remote_host to be set (for logging, or for the env var
9343 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
9346 *) mod_access overhaul:
9347 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
9348 and cidr syntax (i.e. 10.1.0.0/16). PR#762
9349 - Critical path was sped up by pre-computing a few things at config time.
9350 - The undocumented syntax "allow user-agents" was removed,
9351 the replacement is "allow from env=foobar" combined with mod_browser.
9352 - When used with hostnames it now forces a double-reverse lookup
9353 no matter what the directory settings are. This double-reverse
9354 doesn't affect any of the other routines that use the remote
9355 hostname. In particular it's still passed to CGIs and the log
9356 without the double-reverse check. Related PR#860.
9359 *) When a large bwrite() occurs (larger than the internal buffer size),
9360 while there is already something in the buffer, apache will combine
9361 the large write and the buffer into a single writev(). (This is
9362 in anticipation of using mmap() for reading files.)
9365 *) In obscure cases where a partial socket write occurred while chunking,
9366 Apache would omit the chunk header/footer on the next block. Cleaned
9367 up other bugs/inconsistencies in error conditions in buff.c. Fixed
9368 a bug where a long pause in DNS lookups could cause the last packet
9369 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
9371 *) API: Added child_exit function to module structure. This is called
9372 once per "heavy-weight process" just before a server child exit()'s
9373 e.g. when max_requests_per_child is reached, etc.
9374 [Doug MacEachern, Dean Gaudet]
9376 *) mod_include cleanup showed that handle_else was being used to handle
9377 endif. It didn't cause problems, but it was cleaned up too.
9380 *) mod_cern_meta would attempt to find meta files for the directory itself
9381 in some cases, but not in others. It now avoids it in all cases.
9384 *) mod_mime_magic would core dump if there was a decompression error.
9385 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
9387 *) PORT: some variants of DGUX require -lsocket -lnsl
9388 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
9390 *) mod_autoindex now allows sorting of FancyIndexed directory listings
9391 by the various fields (name, size, et cetera), either in ascending
9392 or descending order. Just click on the column header. [Ken Coar]
9394 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
9395 CPUs like the Alpha. Apache still stores ints in pointers, but that's
9396 the relatively safe direction. [Dean Gaudet] PR#344
9398 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
9399 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
9401 *) child_main avoids an unneeded call to select() when there is only one
9402 listening socket. [Dean Gaudet]
9404 *) In the event that the server is starved for idle servers it will
9405 spawn 1, then 2, then 4, ..., then 32 servers each second,
9406 doubling each second. It'll also give a warning in the errorlog
9407 since the most common reason for this is a poor StartServers
9408 setting. The define MAX_SPAWN_RATE can be used to raise/lower
9409 the maximum. [Dean Gaudet]
9411 *) Apache now provides an effectively unbuffered connection for
9412 CGI scripts. This means that data will be sent to the client
9413 as soon as the CGI pauses or stops output; previously, Apache would
9414 buffer the output up to a fixed buffer size before sending, which
9415 could result in the user viewing an empty page until the CGI finished
9416 or output a complete buffer. It is no longer necessary to use an
9417 "nph-" CGI to get unbuffered output. Given that most CGIs are written
9418 in a language that by default does buffering (e.g. perl) this
9419 shouldn't have a detrimental effect on performance.
9421 "nph-" CGIs, which formerly provided a direct socket to the client
9422 without any server post-processing, were not fully compatible with
9423 HTTP/1.1 or SSL support. As such they would have had to implement
9424 the transport details, such as encryption or chunking, in order
9425 to work properly in certain situations. Now, the only difference
9426 between nph and non-nph scripts is "non-parsed headers".
9427 [Dean Gaudet, Sameer Parekh, Roy Fielding]
9429 *) If a BUFF is switched from buffered to unbuffered reading the first
9430 bread() will return whatever remained in the buffer prior to the
9431 switch. [Dean Gaudet]
9433 Changes with Apache 1.3a1
9435 *) Added another Configure helper script: TestLib. It determines
9436 if a specified library exists. [Jim Jagielski]
9438 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
9439 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
9442 *) PORT: Some architectures use size_t for various lengths in network
9443 functions such as accept(), and getsockname(). The definition
9444 NET_SIZE_T is used to control this. [Dean Gaudet]
9446 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
9447 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
9448 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
9450 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
9451 [Igor N Kovalenko <infoh@mail.wplus.net>]
9453 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
9454 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
9455 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
9456 [Dean Gaudet] related PR#875
9458 *) API: Correct child_init() slot declaration from int to void, to
9459 match the init() declaration. Update mod_example to use the new
9462 *) added transport handle slot (t_handle) to the BUFF structure
9465 *) get_client_block() returns wrong length if policy is
9466 REQUEST_CHUNKED_DECHUNK.

9473 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
9474 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
9476 *) AddModuleInfo directive for mod_info which allows you to annotate
9477 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9479 *) Added NoProxy directive to avoid using ProxyRemote for selected
9480 addresses. Added ProxyDomain directive to cause unqualified
9481 names to be qualified by redirection.
9482 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
9484 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
9485 header to the remote host in the proxy. [Sameer Parekh and
9488 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
9489 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
9490 URLs, fixed rewritelog(), fixed forced response code handling on
9491 redirects from within .htaccess files, disabled pipe locking under
9492 braindead SunOS 4.1.x, allow env variables to be set even on rules with
9493 no substitution, bugfixed situations where HostnameLookups is off, made
9494 mod_rewrite more thread-safe for NT port and fixed problem when creating
9495 an empty query string via "xxx?".
9496 This update also removes the copyright of Ralf S. Engelschall,
9497 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
9498 exclusively copyrighted by the Apache Group now. This happened because
9499 the author now has gifted mod_rewrite exclusively to the Apache Group and
9500 no longer maintains an external version.
9501 [Ralf S. Engelschall]
9503 *) API: Added child_init function to module structure. This is called
9504 once per "heavy-weight process" before any requests are handled.
9505 See http_config.h for more details. [Dean Gaudet]
9507 *) Anonymous_LogEmail was logging on each subrequest.
9508 [Dean Gaudet] PR#421, 868
9510 *) API: Added is_initial_req() which tests if the request being
9511 processed is the initial request, or a subrequest.
9514 *) Extended SSI (mod_include) now handles additional relops for
9515 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
9517 *) Configure fixed to correctly propagate user-selected options and
9518 settings (such as CC and OPTIM) to Makefiles other than
9519 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
9521 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
9522 directory indices to start with the contents of the HeaderName file
9523 if there is one. If there isn't one, the behaviour is unchanged.
9524 [Ken Coar, Roy Fielding, Andrey A. Chernov]
9526 *) WIN32: Modules can now be dynamically loaded DLLs using the
9527 LoadModule/LoadFile directives. Note that module DLLs must be
9528 compiled with the multithreaded DLL version of the runtime library.
9529 [Alexei Kosut and Ben Laurie]
9531 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
9532 This allows the admin to completely remove automatic indexing
9533 from the server, while still supporting the basic functions of
9534 trailing-slash redirects and DirectoryIndex files. Note that if
9535 you're carrying over an old Configuration file and you use directory
9536 indexing then you'll want to add:
9538 Module autoindex_module mod_autoindex.o
9540 before mod_dir in your Configuration. [Dean Gaudet]
9542 *) popendir/pclosedir created to properly protect directory scanning.
9543 [Dean Gaudet] PR#525
9545 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
9546 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
9547 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
9550 *) The AccessFileName directive can now take more than one filename.
9551 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9553 *) The new mod_mime_magic can be used to "magically" determine the type
9554 of a file if the extension is unknown. Based on the unix file(1)
9555 command. [Ian Kluft <ikluft@cisco.com>]
9557 *) We now determine and display the time spent processing a
9558 request if desired. [Jim Jagielski]
9560 *) mod_status: PID field of "dead" child slots no longer displays
9561 main httpd process's PID. [Jim Jagielski]
9563 *) Makefile.nt added - to build all the bits from the command line:
9564 nmake -f Makefile.nt
9565 Doesn't yet work properly. [Ben Laurie]
9567 *) Default text of 404 error is now "Not Found" rather than the
9568 potentially misleading "File Not Found". [Ken Coar]
9570 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
9571 for the net if we require people that actually need this data to
9572 enable it. [Linus Torvalds]
9574 *) directory_walk() is an expensive function, keep a little more state to
9575 avoid needless string counting. Add two new functions make_dirstr_parent
9576 and make_dirstr_prefix which replace all existing uses of make_dirstr.
9577 The new functions are a little less general than make_dirstr, but
9578 work more efficiently (less memory, less string counting).
9581 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
9582 to LDFLAGS) to avoid complications with lex rules in make files.
9583 [Dean Gaudet] PR#372
9585 *) run_method optimized to avoid needless scanning over NULLs in the
9586 module list. [Dean Gaudet]
9588 *) Revamp of (unix) scoreboard management code such that it avoids
9589 unnecessary traversals of the scoreboard on each hit. This is
9590 particularly important for high volume sites with a large
9591 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
9592 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
9593 httpd.h. [Dean Gaudet]
9595 *) In configurations using multiple Listen statements it was possible for
9596 busy sockets to starve other sockets of service. [Dean Gaudet]
9598 *) Added hook so standalone_main can be replaced at compile time
9599 (define STANDALONE_MAIN)
9602 *) Lowest-level read/write functions in buff.c will be replaced with
9603 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
9604 compile time. The default sfio discipline will behave as apache
9605 would without sfio compiled in.
9608 *) Enhance UserDir directive (mod_userdir) to accept a list of
9609 usernames for the 'disable' keyword, and add 'enable user...' to
9610 selectively *en*able userdirs if they're globally disabled.
9613 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
9614 will work with Netscape dbm files. (dbmmanage will probably not
9615 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
9617 *) Add a ListenBacklog directive to control the backlog parameter
9618 passed to listen(). Also change the default to 511 from 512.
9621 *) API: A new handler response DONE which informs apache that the
9622 request has been handled and it can finish off quickly, similar to
9623 how it handles errors. [Rob Hartill]
9625 *) Turn off chunked encoding after sending terminating chunk/footer
9626 so that we can't do it twice by accident. [Roy Fielding]
9628 *) mod_expire also issues Cache-Control: max-age headers.
9631 *) API: Added kill_only_once option for free_proc_chain so that it won't
9632 aggressively try to kill off specific children. For fastcgi.
9633 [Stanley Gambarin <gambarin@OpenMarket.com>]
9635 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
9637 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
9638 When used together, these cause mod_dir to emit HEIGHT and WIDTH
9639 attributes in the FancyIndexing IMG tags. [Ken Coar]
9641 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
9643 *) PORT: Added Windows NT support
9644 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
9646 Changes with Apache 1.2.6
9648 *) mod_include when using XBitHack Full would send ETags in addition to
9649 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
9650 [Dean Gaudet] PR#1133
9652 *) SECURITY: When a client connects to a particular port/addr, and
9653 gives a Host: header ensure that the virtual host requested can
9654 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
9656 *) Support virtual hosts with wildcard port and/or multiple ports
9657 properly. [Ed Korthof <ed@organic.com>]
9659 *) Fixed some case-sensitivity issues according to RFC2068.
9662 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
9663 and mod_include.c. [Dean Gaudet]
9665 *) Variable 'cwd' was being used pointlessly before being set.
9668 *) SIGURG doesn't exist on all platforms.
9669 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
9671 *) When an error occurs during a POST, or other operation with a
9672 request body, the body has to be read from the net before allowing
9673 a keepalive session to continue. [Roy Fielding] PR#1399
9675 *) When an error occurs in fcntl() locking suggest the user look up
9676 the docs for LockFile. [Dean Gaudet]
9678 *) table_set() and table_unset() did not deal correctly with
9679 multiple occurrences of the same key. [Stephen Scheck
9680 <sscheck@infonex.net>, Ben Laurie] PR#1604
9682 *) send_fd_length() did not calculate total_bytes_sent properly in error
9683 cases. [Ben Reser <breser@regnow.com>] PR#1366
9685 *) r->connection->user was allocated in the wrong pool causing corruption
9686 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
9688 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9689 Also removed the auto-generated link to www.apache.org that was the
9690 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
9692 *) Multiple "close" tokens may have been set in the "Connection"
9693 header, not an error, but a waste.
9694 [Ronald.Tschalaer@psi.ch] PR#1683
9696 *) "basic" and "digest" auth tokens should be tested case-insensitive.
9697 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
9699 *) It appears the "257th byte" bug (see
9700 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
9701 at the 256th byte as well. Fixed. [Dean Gaudet]
9703 *) mod_rewrite would not handle %3f properly in some situations.
9706 *) Apache could generate improperly chunked HTTP/1.1 responses when
9707 the bputc() or rputc() functions were used by modules (such as
9708 mod_include). [Dean Gaudet]
9710 *) #ifdef wrap a few #defines in httpd.h to make life easier on
9711 some ports. [Ralf Engelschall]

9715 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
9717 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
9719 Changes with Apache 1.2.5
9721 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
9722 only an issue on systems without a MAXDNAME define or where
9723 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
9725 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
9728 *) Fix core dump in the ftp proxy when reading incorrectly formatted
9729 directory listings. [Marc Slemko]
9731 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
9734 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
9735 is used to read various types of files such as htaccess and
9736 htpasswd files. [Marc Slemko]
9738 *) SECURITY: Ensure that the buffer returned by ht_time is always
9739 properly null terminated. [Marc Slemko]
9741 *) SECURITY: General mod_include cleanup, including fixing several
9742 possible buffer overflows and a possible infinite loop. This cleanup
9743 was done against 1.3 code and then backported to 1.2, the result
9744 is a large difference (due to indentation cleanup in 1.3 code).
9745 Users interested in seeing a smaller set of relevant differences
9746 should consider comparing against src/modules/standard/mod_include.c
9747 from the 1.3b3 release. Non-indentation changes to mod_include
9748 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
9750 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9751 including fixing a possible buffer overflow. This cleanup also
9752 was done with 1.3 code as a basis, see the the previous note
9753 about mod_include. [Dean Gaudet]
9755 *) SECURITY: If a htaccess file can not be read due to bad
9756 permissions, deny access to the directory with a HTTP_FORBIDDEN.
9757 The previous behavior was to ignore the htaccess file if it could not
9758 be read. This change may make some setups with unreadable
9759 htaccess files stop working. PR#817 [Marc Slemko]
9761 *) SECURITY: no2slash() was O(n^2) in the length of the input.
9762 Make it O(n). This inefficiency could be used to mount a denial
9763 of service attack against the Apache server. Thanks to
9764 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
9767 *) mod_include used uninitialized data for some uses of && and ||.
9768 [Brian Slesinsky <bslesins@wired.com>] PR#1139
9770 *) mod_imap should decline all non-GET methods.
9771 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
9773 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
9775 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
9776 r->filename. Since those two are meant to be in sync with each other
9777 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
9779 *) mod_include did not properly handle all possible redirects from sub-
9780 requests. [Ken Coar]
9782 *) Inetd mode (which is buggy) uses timeouts without having setup the
9783 jmpbuffer. [Dean Gaudet] PR#1064
9785 *) Work around problem under Linux where a child will start looping
9786 reporting a select error over and over.
9787 [Rick Franchuk <rickf@transpect.net>] PR#1107
9789 Changes with Apache 1.2.4
9791 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
9792 always making requests with the full-URI instead of just the URI path.
9793 [Marc Slemko, Roy Fielding]
9795 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
9796 on this platform. [Marc Slemko]
9798 Changes with Apache 1.2.3
9800 *) The request to a remote proxy was mangled if it was generated as the
9801 result of a ProxyPass directive. URL schemes other than http:// were not
9802 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
9803 PR#812 [Lars Eilebrecht]
9805 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9806 information for case where proxy module is not available. [Marc Slemko]
9808 *) Force proxy to always respond as HTTP/1.0, which it was failing to
9809 do for errors and cached responses. [Roy Fielding]
9811 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
9813 Changes with Apache 1.2.2 [not released]
9815 *) Fixed another long-standing bug in sub_req_lookup_file where it would
9816 happily skip past access checks on subdirectories looked up with relative
9817 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
9820 *) Add lockfile name to error message printed out when
9821 USE_FLOCK_SERIALIZED_ACCEPT is defined.
9824 *) Enhanced the chunking and error handling inside the buffer functions.
9825 [Dean Gaudet, Roy Fielding]
9827 *) When merging the main server's <Directory> and <Location> sections into
9828 a vhost, put the main server's first and the vhost's second. Otherwise
9829 the vhost can't override the main server. [Dean Gaudet] PR#717
9831 *) The <Directory> code would merge and re-merge the same section after
9832 a match was found, possibly causing problems with some modules.
9835 *) Fixed an infinite loop in mod_imap for references above the server root.
9836 [Dean Gaudet] PR#748
9838 *) mod_include cleanup showed that handle_else was being used to handle
9839 endif. It didn't cause problems, but it was cleaned up too.
9842 *) Last official synchronization of mod_rewrite with author version (because
9843 mod_rewrite is now directly developed by the author at the Apache Group):
9844 o added diff between mod_rewrite 3.0.6+ and 3.0.9
9845 minus WIN32/NT stuff, but plus copyright removement.
9847 - workaround for detecting infinite rewriting loops
9848 - fixed setting of env vars when "-" is used as subst string
9849 - fixed forced response code on redirects (PR#777)
9850 - fixed cases where r->args is ""
9851 - kludge to disable locking on pipes under braindead SunOS
9852 - fix for rewritelog in cases where remote hostname is unknown
9853 - fixed totally damaged request_rec walk-back loop
9854 o remove static from local data and add static to global ones.
9855 o replaced ugly proxy finding stuff by simple
9856 find_linked_module("mod_proxy") call.
9857 o added missing negation char on rewritelog()
9858 o fixed a few comment typos
9859 [Ralf S. Engelschall]
9861 *) Anonymous_LogEmail was logging on each subrequest.
9862 [Dean Gaudet] PR#421, PR#868
9864 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
9865 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
9866 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
9867 Additionally mod_browser now triggers during translate_name to workaround
9868 a deficiency in the header_parse phase.

9875 *) Properly treat <files> container like other containers in mod_info.
9876 [Marc Slemko] PR#848
9878 *) The proxy didn't treat the "Host:" keyword of the host header as case-
9879 insensitive. The proxy would corrupt the first line of a response from
9880 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
9882 *) mod_include would log some bogus values occasionally.
9883 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
9885 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
9886 under Solaris 2.x (up through 2.5.1). It has been fixed.
9887 [Dean Gaudet] PR#832
9889 *) API: In HTTP/1.1, whether or not a request message contains a body
9890 is independent of the request method and based solely on the presence
9891 of a Content-Length or Transfer-Encoding. Therefore, our default
9892 handlers need to be prepared to read a body even if they don't know
9893 what to do with it; otherwise, the body would be mistaken for the
9894 next request on a persistent connection. discard_request_body()
9895 has been added to take care of that. [Roy Fielding] PR#378
9897 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
9898 release version number, such that it always increases along the
9899 same lines as our source code branching. [Roy Fielding]
9901 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
9903 Changes with Apache 1.2.1
9905 *) SECURITY: Don't serve file system objects unless they are plain files,
9906 symlinks, or directories. This prevents local users from using pipes
9907 or named sockets to invoke programs for an extremely crude form of

9911 could contain "../" allowing a local user to "publish" any file on
9912 the system. No slashes are allowed now. [Dean Gaudet]
9914 *) SECURITY: It was possible to violate the symlink Options using mod_dir
9915 (headers, readmes, titles), mod_negotiation (type maps), or
9916 mod_cern_meta (meta files). [Dean Gaudet]
9918 *) SECURITY: Apache will refuse to run as "User root" unless
9919 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
9921 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
9922 if it contained a .htaccess disallowing symlinks. This is contrary
9923 to the rule that symlink permissions are tested with the symlink
9924 options of the parent directory. [Dean Gaudet] PR#353
9926 *) CONFIG: The LockFile directive can be used to place the serializing
9927 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
9928 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
9931 *) Request processing now retains state of whether or not the request
9932 body has been read, so that internal redirects and subrequests will
9933 not try to read it twice (and block). [Roy Fielding]
9935 *) Add a placeholder in modules/Makefile to avoid errors with certain
9936 makes. [Marc Slemko]
9938 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
9939 [Dean Gaudet] PR#644
9941 *) mod_include was not properly changing the current directory.
9942 [Marc Slemko] PR#742
9944 *) Attempt to work around problems with third party libraries that do not
9945 handle high numbered descriptors (examples include bind, and
9946 solaris libc). On all systems apache attempts to keep all permanent
9947 descriptors above 15 (called the low slack line). Solaris users
9948 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
9949 which keeps all non-FILE * descriptors above 255. On all systems
9950 this should make supporting large numbers of vhosts with many open
9951 log files more feasible. If this causes trouble please report it,
9952 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
9953 [Dean Gaudet] various PRs
9955 *) Related to the last entry, network sockets are now opened before
9956 log files are opened. The only known case where this can cause
9957 problems is under Solaris with many virtualhosts and many Listen
9958 directives. But using -DHIGH_SLACK_LINE=256 described above will
9959 work around this problem. [Dean Gaudet]
9961 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
9964 *) Improved unix error response logging. [Marc Slemko]
9966 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
9967 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
9968 when a URL http://... was used in conjunction with a special
9969 redirect flag, e.g. R=permanent, the permanent status was lost.

10010 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
10011 [Doug MacEachern, Rob Hartill]
10013 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
10014 reading from one buffer and writing to another, at least until it has
10015 a custom timeout handler. [Roy Fielding and Petr Lampa]
10017 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
10018 apparently due to a mismatch between sigaction and setjmp.
10019 [Roy Fielding] PR#502
10021 *) Log correct status code if we timeout before receiving a request (408)
10022 or if we received a request-line that was too long to process (414).

10025 *) Virtual hosts with the same ServerName, but on different ports, were
10026 not being selected properly. [Ed Korthof]

10030 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
10031 [Chuck Murcko] PR#614
10033 *) If multiple requests on a single connection are used to retrieve
10034 data from different virtual hosts, the virtual host list would be
10035 scanned starting with the most recently used VH instead of the first,
10036 causing most virtual hosts to be ignored.

10046 has found matching variants, but none are acceptable, return the
10047 negotiation result if there are no more DirectoryIndex names to lookup.
10048 [Petr Lampa and Roy Fielding]
10050 *) If a soft_timeout occurs after keepalive is set, then the main child
10051 loop would try to read another request even though the connection
10052 has been aborted. [Roy Fielding]
10054 *) Configure changes: Allow for whitespace at the start of a
10055 Module declaration. Also, be more understanding about the
10056 CC=/OPTIM= format in Configuration. Finally, fix compiler
10057 flags if using HP-UX's cc compiler. [Jim Jagielski]
10059 *) Subrequests and internal redirects now inherit the_request from the
10060 original request-line. [Roy Fielding]
10062 *) Test for error conditions before creating output header fields, since
10063 we don't want the error message to include those fields. Likewise,
10064 reset the content_language(s) and content_encoding of the response
10065 before generating or redirecting to an error message, since the new
10066 message will have its own Content-* definitions. [Dean Gaudet]

10069 and 304 responses) and err_headers_out (headers sent with all responses).
10070 Avoid the overhead of copying tables if err_headers_out is empty
10071 (the usual case). [Roy Fielding]
10073 *) Fixed a couple places where a check for the default Content-Type was
10074 not properly checking both the value configured by the DefaultType
10075 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
10076 of DEFAULT_TYPE to match the documented default (text/plain).

10082 *) Properly initialize the flock structures used by the mutex locking
10083 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
10086 *) The method for determining PATH_INFO has been restored to the pre-1.2b
10087 (and NCSA httpd) definition wherein it was the extra path info beyond
10088 the CGI script filename. The environment variable FILEPATH_INFO has
10089 been removed, and instead we supply the original REQUEST_URI to any
10090 script that wants to be Apache-specific and needs the real URI path.
10091 This solves a problem with existing scripts that use extra path info
10092 in the ScriptAlias directive to pass options to the CGI script.
10095 *) The _default_ change in 1.2b10 will change the behaviour on configs
10096 that use multiple Listen statements for listening on multiple ports.
10097 But that change is necessary to make _default_ consistent with other
10098 forms of <VirtualHost>. It requires such configs to be modified
10099 to use <VirtualHost _default_:*>. The documentation has been
10100 updated. [Dean Gaudet] PR#530
10102 *) If an ErrorDocument CGI script is used to respond to an error
10103 generated by another CGI script which has already read the message

10185 at the 256th or 257th byte of output, then Navigator will think a normal
10186 image is invalid. We are guessing that this is because their initial
10187 read of a new request uses a 256 byte buffer. We check the bytes written
10188 so far and, if we are about to tickle the bug, we instead insert a
10189 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
10191 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
10192 of an external redirection. [Roy Fielding and Paul Sutton]
10194 *) Configure would create a broken Makefile if the configuration file
10195 contained a commented-out Rule. [Roy Fielding]
10197 *) Promote per_dir_config and subprocess_env from the subrequest to the
10198 main request in mod_negotiation. In particular this fixes a bug
10199 where <Files> sections wouldn't properly apply to negotiated content.
10202 *) Fix a potential deadlock in mod_cgi script_err handling.
10203 [Ralf S. Engelschall]
10205 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
10206 [Mitchell Blank Jr]
10208 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
10209 .htaccess files because the RewriteBase was not replaced correctly.
10210 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
10211 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
10213 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
10214 1.x the settings are those of pre-1.2b8. For 2.x we include
10215 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
10216 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
10217 [Dean Gaudet] PR#336, PR#340
10219 *) Redirect did not preserve ?query_strings when present in the client's
10220 request. [Dean Gaudet]
10222 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
10224 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
10226 *) Add UnixWare compile/install instructions. [Chuck Murcko]
10228 *) Add mod_example (illustration of API techniques). [Ken Coar]
10230 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
10232 *) Improve handling of directories when filenames have spaces in them.
10235 *) For hosts with multiple IP addresses, try all additional addresses if
10236 necessary to get a connect. Fail only if hostent address list is
10237 exhausted. [Chuck Murcko]
10239 *) More signed/unsigned port fixes. [Dean Gaudet]
10241 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
10244 Changes with Apache 1.2b8
10246 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
10247 to it. [Marc Slemko]
10249 *) The addition of <Location> and <File> directives made the
10250 sub_req_lookup_simple() function bogus, so we now handle
10251 the special cases directly. [Dean Gaudet]
10253 *) We now try to log where the server is dumping core when a fatal
10254 signal is received. [Ken Coar]
10256 *) Improved lingering_close by adding a special timeout, removing the
10257 spurious log messages, removing the nonblocking settings (they
10258 are not needed with the better timeout), and adding commentary
10259 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
10260 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
10262 *) Send error messages about setsockopt failures to the server error
10263 log instead of stderr. [Roy Fielding]
10265 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
10267 *) Stopgap solution for CGI 3-second delay with server-side includes: if
10268 processing a subrequest, allocate memory from r->main->pool instead
10269 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
10270 in the middle of an SSI request. [Dean Gaudet] PR #122
10272 *) Fixed status of response when POST is received for a nonexistent URL
10273 (was sending 405, now 404) and when any method is sent with a
10274 full-URI that doesn't match the server and the server is not acting
10275 as a proxy (was sending 501, now 403). [Roy Fielding]
10277 *) Host port changed to unsigned short. [Ken Coar] PR #276
10279 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
10281 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
10283 *) Report extra info from errno with many errors that cause httpd to exit.
10284 spawn_child, popenf, and pclosef now have valid errno returns in the
10285 event of an error. Correct problems where errno was stomped on
10286 before being reported. [Dean Gaudet]
10288 *) In the proxy, if the cache filesystem was full, garbage_coll() was
10289 never called, and thus the filesystem would remain full indefinitely.
10290 We now also remove incomplete cache files left if the origin server
10291 didn't send a Content-Length header and either the client has aborted
10292 transfer or bwrite() to client has failed. [Petr Lampa]
10294 *) Fixed the handling of module and script-added header fields.
10295 Improved the interface for sending header fields and reduced
10296 the duplication of code between sending okay responses and errors.
10297 We now always send both headers_out and err_headers_out, and
10298 ensure that the server-reserved fields are not being overridden,
10299 while not overriding those that are not reserved. [Roy Fielding]
10301 *) Moved transparent content negotiation fields to err_headers_out
10302 to reflect above changes. [Petr Lampa]
10304 *) Fixed the determination of whether or not we should make the
10305 connection persistent for all of the cases where some other part
10306 of the server has already indicated that we should not. Also
10307 improved the ordering of the test so that chunked encoding will
10308 be set whenever it is desired instead of only when KeepAlive
10309 is enabled. Added persistent connection capability for most error
10310 responses (those that do not indicate a bad input stream) when
10311 accessed by an HTTP/1.1 client. [Roy Fielding]
10313 *) Added missing timeouts for sending header fields, error responses,
10314 and the last chunk of chunked encoding, each of which could have
10315 resulted in a process being stuck in write forever. Using soft_timeout
10316 requires that the sender check for an aborted connection rather than
10317 continuing after an EINTR. Timeouts that used to be initiated before
10318 send_http_header (and never killed) are now initiated only within or
10319 around the routines that actually do the sending, and not allowed to
10320 propagate above the caller. [Roy Fielding]
10322 *) mod_auth_anon required an @ or a . in the email address, not both.
10325 *) per_dir_defaults weren't set correctly until directory_walk for
10326 name-based vhosts. This fixes an obscure bug with the wrong config
10327 info being used for vhosts that share the same ip as the server.
10330 *) Improved generation of modules/Makefile to be more generic for
10331 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
10333 *) Generate makefile dependency for Configuration based on the actual
10334 name given when running the Configure process. [Dean Gaudet]
10336 *) Fixed problem with vhost error log not being set prior to
10337 initializing virtual hosts. [Dean Gaudet]
10339 *) Fixed infinite loop when a trailing slash is included after a type map
10340 file URL (extra path info). [Petr Lampa]
10342 *) Fixed server status updating of per-connection counters. [Roy Fielding]
10344 *) Add documentation for DNS issues (reliability and security), and try
10345 to explain the virtual host matching process. [Dean Gaudet]
10347 *) Try to continue gracefully by disabling the vhost if a DNS lookup
10348 fails while parsing the configuration file. [Dean Gaudet]
10350 *) Improved calls to setsockopt. [Roy Fielding]
10352 *) Negotiation changes: Don't output empty content-type in variant list;
10353 Output charset in variant list; Return sooner from handle_multi() if
10354 no variants found; Add handling of '*' wildcard in Accept-Charset.
10355 [Petr Lampa and Paul Sutton]
10357 *) Fixed overlaying of request/sub-request notes and headers in
10358 mod_negotiation. [Dean Gaudet]
10360 *) If two variants' charset quality are equal and one is the default
10361 charset (iso-8859-1), then prefer the variant that was specifically
10362 listed in Accept-Charset instead of the default. [Petr Lampa]
10364 *) Memory allocation problem in push_array() -- it would corrupt memory
10365 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
10367 *) invoke_handler() doesn't handle mime arguments in content-type
10368 [Petr Lampa] PR#160
10370 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
10373 *) Fixed problem with ErrorDocument not working for virtual hosts
10374 due to one of the performance changes in 1.2b7. [Dean Gaudet]
10376 *) Log an error message if we get a request header that is too long,
10377 since it may indicate a buffer overflow attack. [Marc Slemko]
10379 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
10380 not reject URLs without a double-slash, as per RFC2068 section 3.2.
10381 [Ken Coar] PR #146, #187
10383 *) Added table entry placeholder for new header_parser callback
10384 in all of the distributed modules. [Ken Coar] PR #191
10386 *) Allow for cgi files without the .EXE extension on them under OS/2.
10387 [Garey Smiley] PR #59
10389 *) Fixed error message when resource is not found and URL contains
10390 path info. [Petr Lampa and Dean Gaudet] PR #40
10392 *) Fixed user and server confusion over what should be a virtual host
10393 and what is the main server, resulting in access to something
10394 other than the name defined in the virtualhost directive (but
10395 with the same IP address) failing. [Dean Gaudet]
10397 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
10398 AIX; improves the redirection stuff to enable the users to generally
10399 redirect to http, https, gopher and ftp; added TIME variable for
10400 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
10401 special patterns >STRING, <STRING and =STRING to RewriteCond, which
10402 can be used in conjunction with %{TIME} or other variables to create
10403 time-dependent rewriting rules. [Ralf S. Engelschall]
10405 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
10406 Module authors may need to adjust their code for proper cleanup to take
10407 place (that is, call note_cleanups_for_fd()). This change fixes problems
10408 with file descriptors being erroneously closed when the proxy module was
10409 in use. [Ben Laurie]
10411 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
10412 initgroups() to hose the group information needed for later
10413 comparisons. [Randy Terbush]
10415 *) Remove unnecessary call to va_end() in create_argv() which
10416 caused a SEGV on some systems.
10418 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
10421 *) Clear memory allocated for listeners. [Randy Terbush]
10423 *) Improved handling of IP address as a virtualhost address and
10424 introduced "_default_" as a synonym for the default vhost config.
10425 [Dean Gaudet] PR #212
10427 Changes with Apache 1.2b7
10429 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
10431 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
10433 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
10434 - replace protocol response numbers with symbols
10435 - save variant-list into main request notes
10436 - free allocated memory from subrequests
10437 - merge notes, headers_out and err_headers_out
10439 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
10440 "HTTP/#.# ###*" to be more lenient about what we accept.
10443 *) more proxy FTP bug fixes:
10444 - Changed send_dir() to remove user/passwd from displayed URL.
10445 - Changed login error messages to be more descriptive.
10446 - remove setting of SO_DEBUG socket option
10447 - Make ftp_getrc() more lenient about multiline responses,
10448 specifically, 230 responses which don't have continuation 230-
10449 on each line). These seem to be all NT FTP servers, and while
10450 perhaps questionable, they appear to be legal by RFC 959.
10451 - Add missing kill_timeout() after transfer to user completes.
10454 *) Fixed problem where a busy server could hang when restarting
10455 after being sent a SIGHUP due to child processes not exiting.
10458 *) Modify mod_include escaping so a '\' only signifies an escaped
10459 character if the next character is one that needs
10460 escaping. [Ben Laurie]
10462 *) Eliminated possible infinite loop in mod_imap when relative URLs are
10463 used with a 'base' directive that does not have a '/' in it.
10464 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
10466 *) Reduced the default timeout from 1200 seconds to 300, and the
10467 one in the sample configfile from 400 to 300. [Marc Slemko]
10469 *) Stop vbprintf from crashing if given a NULL string pointer;
10470 print (null) instead. [Ken Coar]
10472 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
10473 [Marc Slemko and Roy Fielding]
10475 *) Fixed problem with mod_cgi-generated internal redirects trying to
10476 read the request message-body twice. [Archie Cobbs and Roy Fielding]
10478 *) Reduced timeout on lingering close, removed possibility of a blocked
10479 read causing the child to hang, and stopped logging of errors if
10480 the socket is not connected (reset by client). [Roy Fielding]
10482 *) Rearranged main child loop to remove duplication of code in
10483 select/accept and keep-alive requests, fixed several bugs regarding
10484 checking scoreboard_image for exit indication and failure to
10485 account for all success conditions and trap all error conditions,
10486 prevented multiple flushes before closing the socket; close the entire
10487 socket buffer instead of just one descriptor, prevent logging of
10488 EPROTO and ECONNABORTED on platforms where supported, and generally
10489 improved readability. [Roy Fielding]
10491 *) Extensive performance improvements. Cleaned up inefficient use of
10492 auto initializers, multiple is_matchexp calls on a static string,
10493 and excessive merging of response_code_strings. [Dean Gaudet]
10495 *) Added double-buffering to mod_include to improve performance on
10496 server-side includes. [Marc Slemko]
10498 *) Several fixes for suexec wrapper. [Randy Terbush]
10499 - Make wrapper work for files on NFS filesystem.
10500 - Fix portability problem of MAXPATHLEN.
10501 - Fix array overrun problem in clean_env().
10502 - Fix allocation of PATH environment variable
10504 *) Removed extraneous blank line is description of mod_status chars.
10507 *) Logging of errors from the call_exec routine simply went nowhere,
10508 since the logfile fd has been closed, so now we send them to stderr.
10509 [Harald T. Alvestrand]
10511 *) Fixed core dump when DocumentRoot is a CGI.
10512 [Ben Laurie, reported by geddis@tesserae.com]
10514 *) Fixed potential file descriptor leak in mod_asis; updated it and
10515 http_core to use pfopen/pfclose instead of fopen/fclose.
10516 [Randy Terbush and Roy Fielding]
10518 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
10519 as the DEC Alpha which is 64-bit but uses 32-bit ints.
10520 [Dean Gaudet and Ken Coar]
10522 *) Return a 302 response code to the client when sending a redirect
10523 due to a missing trailing '/' on a directory instead of a 301; now
10524 it is cacheable. [Markus Gyger]
10526 *) Fix condition where, if a bad directive occurs in .htaccess, and
10527 sub_request() goes first to this directory, then log_reason() will
10528 SIGSEGV because it doesn't have initialized r->per_dir_config.
10529 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
10531 *) Fix handling of lang_index in is_variant_better(). This was
10532 causing problems which resulted in the server sending the
10533 wrong language document in some cases. [Petr Lampa]
10535 *) Remove free() from clean_env() in suexec wrapper. This was nuking
10536 the clean environment on some systems.
10538 *) Tweak byteserving code (e.g. serving PDF files) to work around
10539 bugs in Netscape Navigator and Microsoft Internet Explorer.
10540 Emit Content-Length header when sending multipart/byteranges.
10543 *) Port to HI-UX/WE2. [Nick Maclaren]
10545 *) Port to HP MPE operating system for HP 3000 machines
10546 [Mark Bixby <markb@cccd.edu>]
10548 *) Fixed bug which caused a segmentation fault if only one argument
10549 given to RLimit* directives. [Ed Korthof]
10551 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
10553 *) Improved buffered output to the client by delaying the flush decision
10554 until the BUFF code is actually about to read the next request.
10555 This fixes a problem introduced in 1.2b5 with clients that send
10556 an extra CRLF after a POST request. Also improved chunked output
10557 performance by combining writes using writev() and removing as
10558 many bflush() calls as possible. NOTE: Platforms without writev()
10559 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
10560 or Configure, unless we have already done so. [Dean Gaudet]
10562 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
10564 *) Fixed mod_info output corruption bug introduced by buffer overflow
10565 fixes. [Dean Gaudet]
10567 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
10568 for the special case of a 304 response. [Paul Sutton]
10570 *) Improved handling of TRACE method by bypassing normal method handling
10571 and header parsing routines; fixed Allow response to always allow TRACE.
10574 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
10576 *) Cleaned-up some of the generated HTML. [Ken Coar]
10578 Changes with Apache 1.2b6
10580 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
10582 *) Fix typo introduced in fix for potential infinite loop around
10583 accept() in child_main(). This change caused the rev to 1.2b6.
10584 1.2b5 was never a public beta.
10586 Changes with Apache 1.2b5
10588 *) Change KeepAlive semantics (On|Off instead of a number), add
10589 MaxKeepAliveRequests directive. [Alexei Kosut]
10591 *) Various NeXT compilation patches, as well as a change in
10592 regex/regcomp.c since that file also used a NEXT define.
10595 *) Allow * to terminate the end of a directory match in mod_dir.
10596 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
10598 *) Don't call can_exec() if suexec_enabled. Calling this requires
10599 scripts executed by the suexec wrapper to be world executable, which
10600 defeats one of the advantages of running the wrapper. [Randy Terbush]
10602 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
10605 *) Migration from sprintf() to snprintf() to avoid buffer
10606 overflows. [Marc Slemko]
10608 *) Provide portable snprintf() implementation (ap_snprintf)
10609 as well as *cvt family. [Jim Jagielski]
10611 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
10614 *) Remove mod_fastcgi.c from the distribution. This module appears
10615 to be maintained more through the Open Market channels and should
10616 continue to be easily available at http://www.fastcgi.com/
10618 *) Fixed bug in modules/Makefile that wouldn't allow building in more
10619 than one subdirectory (or cleaning, either). [Jeremy Laidman]
10621 *) mod_info assumed that the config files were relative to ServerRoot.
10624 *) CGI scripts called as an error document resulting from failed
10625 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
10627 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
10630 *) Properly check errno to prevent display of a directory index
10631 when server receives a long enough URL to confuse stat().
10634 *) Several security enhancements to suexec wrapper. It is _highly_
10635 recommended that previously installed versions of the wrapper
10636 be replaced with this version. [Randy Terbush, Jason Dour]
10638 - ~user execution now properly restricted to ~user's home
10639 directory and below.
10640 - execution restricted to UID/GID > 100
10641 - restrict passed environment to known variables
10642 - call setgid() before initgroups() (portability fix)
10643 - remove use of setenv() (portability fix)
10645 *) Add HTTP/1.0 response forcing. [Ben Laurie]
10647 *) Add access control via environment variables. [Ben Laurie]
10649 *) Add rflush() function. [Alexei Kosut]
10651 *) remove duplicate pcalloc() call in new_connection().
10653 *) Fix incorrect comparison which could allow number of children =
10654 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
10655 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
10657 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
10658 AIX PS/2, CONVEXOS. [Jim Jagielski]
10660 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
10661 It's more portable. [Martin Kraemer]
10663 *) Replace references to make in Makefile.tmpl with $(MAKE).
10666 *) Add ProxyBlock directive w/IP address caching. Add IP address
10667 caching to NoCache directive as well. ProxyBlock works with all
10668 handlers; NoCache now also works with FTP for anonymous logins.
10669 Still more code cleanup. [Chuck Murcko]
10671 *) Add "header parse" API hook [Ben Laurie]
10673 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
10675 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
10677 *) Correctly allow access and auth directives in <Files> sections in
10678 server config files. [Alexei Kosut]
10680 *) Fix bug with ServerPath that could cause certain files to be not
10681 found by the server. [Alexei Kosut]
10683 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
10684 double-quote from text and so that it properly checks for unsupported
10685 status codes using the new index_of_response interface. [Roy Fielding]
10687 *) Multiple fixes to the lingering_close code in order to avoid being
10688 interrupted by a stray timeout, to avoid lingering on a connection
10689 that has already been aborted or never really existed, to ensure that
10690 we stop lingering as soon as any error condition is received, and to
10691 prevent being stuck indefinitely if the read blocks. Also improves
10692 reporting of error conditions. [Marc Slemko and Roy Fielding]
10694 *) Fixed initialization of parameter structure for sigaction.
10695 [mgyger@itr.ch, Adrian Filipi-Martin]
10697 *) Fixed reinitializing the parameters before each call to accept and
10698 select, and removed potential for infinite loop in accept.
10699 [Roy Fielding, after useful PR from adrian@virginia.edu]
10701 *) Fixed condition where, if a child fails to fork, the scoreboard would
10702 continue to say SERVER_STARTING forever. Eventually, the main process
10703 would refuse to start new children because count_idle_servers() will
10704 count those SERVER_STARTING entries and will always report that there
10705 are enough idle servers. [Phillip Vandry]
10707 *) Fixed bug in bcwrite regarding failure to account for partial writes.
10708 Avoided calling bflush() when the client is pipelining requests.
10709 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
10711 *) Added description of "." mode in server-status [Jim Jagielski]
10713 Changes with Apache 1.2b4
10715 *) Fix possible race condition in accept_mutex_init() that
10716 could leave a small security hole open allowing files to be
10717 overwritten in cases where the server UID has write permissions.
10720 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
10722 *) Fix portablity problem in util_script where ARG_MAX may not be
10723 defined for some systems.
10725 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
10728 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
10729 style magic #! token for better script portability. [Garey Smiley]
10731 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
10732 execution for ~userdir CGI. [Jason Dour]
10734 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
10736 *) Fix month off by one in suexec wrapper logging.
10738 Changes with Apache 1.2b3:
10740 *) Fix error in mod_cgi which could cause resources not to be properly
10741 freed, or worse. [Dean Gaudet]
10743 *) Fix find_string() NULL pointer dereference. [Howard Fear]
10745 *) Add set_flag_slot() at the request of Dirk and others.
10748 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
10750 *) Add changes to improve the error message given for invalid
10751 ServerName parameters. [Dirk vanGulik]
10753 *) Add "Authoritative" directive for Auth modules that don't
10754 currently have it. This gives admin control to assign authoritative
10755 control to an authentication scheme and allow "fall through" for
10756 those authentication modules that aren't "Authoritative" thereby
10757 allowing multiple authentication mechanisms to be chained.
10760 *) Remove requirement for ResourceConfig/AccessConfig if not using
10761 the three config file layout. [Randy Terbush]
10763 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
10765 *) Changes to suexec wrapper to fix the following problems:
10766 1. symlinked homedirs will kill ~userdirs.
10767 2. initgroups() on Linux 2.0.x clobbers gr->grid.
10768 3. CGI command lines paramters problems
10769 4. pw-pwdir for "docroot check" still the httpd user's pw record.
10770 [Randy Terbush, Jason Dour]
10772 *) Change create_argv() to accept variable arguments. This fixes
10773 a problem where arguments were not getting passed to the CGI via
10774 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
10776 *) Collapse multiple slashes in path URLs to properly apply
10777 handlers defined by <Location>. [Alexei Kosut]
10779 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
10781 *) Improve the accuracy of request duration timings by setting
10782 r->request_time in read_request_line() instead of read_request().
10785 *) Reset timeout while reading via get_client_block() in mod_cgi.c
10786 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
10788 *) Add the ability to pass different Makefile.tmpl files to Configure
10789 using the -make flag. [Rob Hartill]
10791 *) Fix coredump triggered when sending a SIGHUP to the server caused
10792 by an assertion failure, in turn caused by an uninitialised field in a
10796 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
10797 PATH_INFO from previous versions of Apache (in certain situations,
10798 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
10799 [later removed in 1.2b11]
10801 *) Add rwrite() function to API to allow for sending strings of
10802 arbitrary length. [Doug MacEachern]
10804 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
10806 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
10807 NeXT. [Jim Jagielski]
10809 *) Removed recent modification to promote the status code on internal
10810 redirects, since the correct fix was to change the default log format
10811 in mod_log_config so that it outputs the original status. [Rob Hartill]
10813 Changes with Apache 1.2b2:
10815 *) Update set_signals() to use sigaction() for setting handlers.
10816 This appears to fix a re-entrant problem in the seg_fault()
10817 bus_error() handlers. [Randy Terbush]
10819 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
10821 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
10823 *) proxy_http.c bugfixes: [Chuck Murcko]
10824 1) fixes possible NULL pointer reference w/NoCache
10825 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
10826 host would cache nothing if it was in the local domain,
10827 and the local domain was in the NoCache list)
10828 3) Adds Host: header when not available
10829 4) Some code cleanup and clarification
10831 *) mod_include.c bugfixes:
10832 1) Fixed an ommission that caused include variables to not
10833 be parsed in config errmsg directives [Howard Fear]
10834 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
10835 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
10836 4) Allow backslash-escaping to all quoted text
10837 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
10838 5) Pass variable to command line if not set in XSSI's env
10841 *) Fix infinite loop when processing Content-language lines in
10842 type-map files. [Alexei Kosut]
10844 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
10846 *) Fixed problem in set_[user|group] that prevented CGI execution
10847 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
10849 *) Added PORTING information file. [Jim Jagielski]
10851 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
10853 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
10855 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
10856 USE_FCNTL_SERIALIZED_ACCEPT was intended.
10858 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
10859 which caused problems of systems where socket s_addr is >32bits.
10861 *) Added comment to explain (r->chunked = 1) side-effect in
10862 http_protocol.c [Roy Fielding]
10864 *) Replaced use of index() in mod_expires.c with more appropriate
10865 and portable isdigit() test. [Ben Laurie]
10867 *) Updated Configure for ...
10868 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
10869 *-dg-dgux* (bad pattern match)
10870 QNX (DEF_WANTHSREGEX=yes)
10871 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
10873 *-unixware211 (new)
10874 and added some user diagnostic info. [Ben Laurie]
10876 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
10877 for better portability. [Jim Jagielski]
10879 *) Updated helpers/GuessOS for ...
10880 SCO 5 (recognize minor releases)
10881 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
10882 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
10883 IRIX64 (-sgi-irix64)
10884 ULTRIX (-unknown-ultrix)
10885 SINIX (-whatever-sysv4)
10886 NCR Unix (-ncr-sysv4)
10887 and fixed something in helpers/PrintPath [Ben Laurie]
10889 Changes with Apache 1.2b1
10891 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
10893 Changes with Apache 1.1.1
10895 *) Fixed bug where Cookie module would make two entries in the
10896 logfile for each access [Mark Cox]
10898 *) Fixed bug where Redirect in .htaccess files would cause memory
10899 leak. [Nathan Neulinger]
10901 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
10903 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
10905 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
10907 Changes with Apache 1.1.0
10909 *) Bring NeXT support up to date. [Takaaki Matsumoto]
10911 *) Bring QNX support up to date. [Ben Laurie]
10913 *) Make virtual hosts default to main server keepalive parameters.
10914 [Alexei Kosut, Ben Laurie]
10916 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
10918 *) Fix missing address family for connect, also remove unreachable statement
10919 in mod_proxy. [Ben Laurie]
10921 *) mod_env now turned on by default in Configuration.tmpl.
10923 *) Bugs which were fixed:
10924 a) yet more mod_proxy bugs [Ben Laurie]
10925 b) CGI works again with inetd [Alexei Kosut]
10926 c) Leading colons were stripped from passwords [osm@interguide.com]
10927 d) Another fix to multi-method Limit problem [jk@tools.de]
10929 Changes with Apache 1.1b4
10931 *) r->bytes_sent variable restored. [Robert Thau]
10933 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
10935 *) More possibly unsecure programs removed from the support directory.
10937 *) More mod_auth_msql authentication improvements.
10939 *) VirtualHosts based on Host: headers no longer conflict with the
10942 *) OS/2 compatibility enhancements. [Gary Smiley]
10944 *) POST now allowed to directory index CGI scripts.
10946 *) Actions now work with files of the default type.
10948 *) Bugs which were fixed:
10949 a) more mod_proxy bugs
10950 b) early termination of inetd requests
10951 c) compile warnings on several systems
10952 d) problems when scripts stop reading output early
10954 Changes with Apache 1.1b3
10956 *) Much of cgi-bin and all of cgi-src has been removed, due to
10957 various security holes found and that we could no longer support
10960 *) The "Set-Cookie" header is now special-cased to not merge multiple
10961 instances, since certain popular browsers can not handle multiple
10962 Set-Cookie instructions in a single header. [Paul Sutton]
10964 *) rprintf() added to buffer code, occurrences of sprintf removed.
10967 *) CONNECT method for proxy module, which means tunneling SSL should work.
10968 (No crypto needed) Also a NoCache config directive.
10970 *) Several API additions: pstrndup(), table_unset() and get_token()
10971 functions now available to modules.
10973 *) mod_imap fixups, in particular Location: headers are now complete
10976 *) New "info" module which reports on installed module set through a
10977 special URL, a la mod_status.
10979 *) "ServerPath" directive added - allows for graceful transition
10980 for Host:-header-based virtual hosts.
10982 *) Anonymous authentication module improvements.
10984 *) MSQL authentication module improvements.
10986 *) Status module design improved - output now table-based. [Ben Laurie]
10988 *) htdigest utility included for use with digest authentication
10991 *) mod_negotiation: Accept values with wildcards to be treated with
10992 less priority than those without wildcards at the same quality
10993 value. [Alexei Kosut]
10995 *) Bugs which were fixed:
10996 a) numerous mod_proxy bugs
10997 b) CGI early-termination bug [Ben Laurie]
10998 c) Keepalives not working with virtual hosts
10999 d) RefererIgnore problems
11000 e) closing fd's twice in mod_include (causing core dumps on
11001 Linux and elsewhere).
11003 Changes with Apache 1.1b2
11006 a) core dumps in mod_digest
11007 b) truncated hostnames/ip address in the logs
11008 c) relative URL's in mod_imap map files
11010 Changes with Apache 1.1b1
11012 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
11014 Changes with Apache 1.0.3
11016 *) Internal redirects which occur in mod_dir.c now preserve the
11017 query portion of a request (the bit after the question mark).
11020 *) Escape active characters '<', '>' and '&' in html output in
11021 directory listings, error messages and redirection links.
11024 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
11026 *) Fix for POSIX compliance in waiting for processes in alloc.c.
11029 *) setsockopt no longer takes a const declared argument [Martijn Koster]
11031 *) Reset timeout timer after each successful fwrite() to the network.
11032 This patch adds a reset_timeout() procedure that is called by
11033 send_fd() to reset the timeout ever time data is written to the net.
11036 *) timeout() signal handler now checks for SIGPIPE and reports
11037 lost connections in a more user friendly way. [Rob Hartill]
11039 *) Location of the "scoreboard" file which used to live in /tmp is
11040 now configurable (for OSes that can't use mmap) via ScoreBoardFile
11041 which works similar to PidFile (in httpd.conf) [Rob Hartill]
11043 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
11045 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
11046 which caused a SEGV with cookies enabled
11048 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
11051 *) Log the UNIX textual error returned by some system calls, in
11052 particular errors from accept() [David Robinson]
11054 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
11056 Changes with Apache 1.0.2
11058 *) patch to get Apache compiled on UnixWare 2.x, recommended as
11059 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
11061 *) Fix get_basic_auth_pw() to set the auth_type of the request.
11064 *) past changes to http_config.c to only use the
11065 setrlimit function on systems defining RLIMIT_NOFILE
11066 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
11067 for SUNOS and prototypes the needed functions.
11069 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
11072 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
11074 *) Merge multiple headers from CGI scripts instead of taking last
11075 one. [David Robinson]
11077 *) Add support for SCO 5. [Ben Laurie]
11079 Changes with Apache 1.0.1
11081 *) Silence mod_log_referer and mod_log_agent if not configured
11084 *) Recursive includes can occur if the client supplies PATH_INFO data
11085 and the server provider uses relative links; as file.html
11086 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
11088 *) The replacement for initgroups() did not call {set,end}grent(). This
11089 had two implications: if anything else used getgrent(), then
11090 initgroups() would fail, and it was consuming a file descriptor.
11093 *) On heavily loaded servers it was possible for the scoreboard to get
11094 out of sync with reality, as a result of a race condition.
11095 The observed symptoms are far more Apaches running than should
11096 be, and heavy system loads, generally followed by catastrophic
11097 system failure. [Ben Laurie]
11099 *) Fix typo in license. [David Robinson]
11101 Changes with Apache 1.0.0 23 Nov 1995
11103 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
11105 Changes with Apache 0.8.16 05 Nov 1995
11107 *) New man page for 'httpd' added to support directory [David Robinson]
11109 *) .htgroup files can have more than one line giving members for a
11110 given group (each must have the group name in front), for NCSA
11111 back-compatibility [Robert Thau]
11113 *) Mutual exclusion around accept() is on by default for SVR4 systems
11114 generally, since they generally can't handle multiple processes in
11115 accept() on the same socket. This should cure flaky behavior on
11116 a lot of those systems. [David Robinson]
11118 *) AddType, AddEncoding, and AddLanguage directives take multiple
11119 extensions on a single command line [David Robinson]
11121 *) UserDir can be disabled for a given virtual host by saying
11122 "UserDir disabled" in the <VirtualHost> section --- it was a bug
11123 that this didn't work. [David Robinson]
11125 *) Compiles on QNX [Ben Laurie]
11127 *) Corrected parsing of ctime time format [David Robinson]
11129 *) httpd does a perror() before exiting if it can't log its pid
11130 to the PidFile, to make diagnosing the error a bit easier.
11133 *) <!--#include file="..."--> can no longer include files in the
11134 parent directory, for NCSA back-compatibility. [David Robinson]
11136 *) '~' is *not* escaped in URIs generated for directory listings
11139 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
11141 *) Fixed bug involving handling URIs with escaped %-characters
11142 in redirects [David Robinson]
11144 Changes with Apache 0.8.15 14 Oct 1995
11146 *) Switched to new, simpler license
11148 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
11150 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
11152 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
11154 *) Correctly handles internal redirects to files with names containing '%'
11157 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
11159 *) Use geteuid() rather than getuid() to see if we have root privilege,
11160 so that server correctly resets privilege if run setuid root. [Andrew
11163 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
11166 *) Fix relative URLs in imagemap files [Randy Terbush]
11168 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
11171 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
11172 entries all name the same one. [David Robinson]
11174 *) Fix directory listings with filenames containing unusual characters
11177 *) Better URI-escaping for generated URIs in directories with filenames
11178 containing unusual characters [Ben Laurie]
11180 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
11182 *) Unblock alarms on error return from spawn_child() [David Robinson]
11184 *) Sample Config files have extra note for SCO users [Ben Laurie]
11186 *) Configuration has note for HP-UX users [Rob Hartill]
11188 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
11190 *) Nuked bogus #define in httpd.h [David Robinson]
11192 *) Better test for whether a system has setrlimit() [David Robinson]
11194 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
11196 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
11199 Changes with Apache 0.8.14 19 Sep 1995
11201 *) Compiles on SCO ODT 3.0 [Ben Laurie]
11203 *) AddDescription works (better) [Ben Laurie]
11205 *) Leaves an intelligible error diagnostic when it can't set group
11206 privileges on standalone startup [Andrew Wilson]
11208 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
11209 that machine, which claims to be BSD but does not support RLIMIT.
11212 *) gcc -Wall no longer complains about an unused variable when util.c
11213 is compiled with -DMINIMAL_DNS [Andrew Wilson]
11215 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
11217 Changes with Apache 0.8.13 07 Sep 1995
11219 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
11221 *) Have built-in imagemap code recognize & honor Point directive [James
11224 *) Generate cleaner directory listings in directories with a mix of
11225 long and short filenames [Rob Hartill]
11227 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
11229 *) Properly default ServerName for virtual servers [Robert Thau]
11231 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
11232 Paul Richards and a cast of thousands...]
11234 *) On self-identified BSD systems (we don't try to guess any more),
11235 allocate a few extra file descriptors per virtual host with setrlimit,
11236 if we can, to avoid running out. [Randy Terbush]
11238 *) Write 22-character lock file name into buffer with enough space
11239 on startup [Konstantin Olchanski]
11241 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
11244 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
11246 *) Suppress -Wall warning by initializing variable in negotiation code
11247 [Tobias Weingartner]
11249 Changes with Apache 0.8.12 31 Aug 1995
11251 *) Doesn't pause three seconds after including a CGI script which is
11252 too slow to die off (this is done by not even trying to kill off
11253 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
11254 after the entire document has been processed). [Robert Thau]
11256 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
11258 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
11260 *) Allows .htaccess files to override <Directory> sections naming the
11261 same directory [David Robinson]
11263 *) Removed an efficiency hack in sub_req_lookup_uri which was
11264 causing certain extremely marginal cases (e.g., ScriptAlias of a
11265 *particular* index.html file) to fail. [David Robinson]
11267 *) Doesn't log an error when the requested URI requires
11268 authentication, but no auth header line was supplied by the
11269 client; this is a normal condition (the client doesn't no auth is
11270 needed here yet). [Robert Thau]
11272 *) Behaves more sanely when the name server loses its mind [Sean Welch]
11274 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
11276 *) RFC931 code no longer passes out name of prior clients on current
11277 requests if the current request came from a server that doesn't
11278 do RFC931. [David Robinson]
11280 *) Configuration script accepts "Module" lines with trailing whitespace.
11283 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
11285 *) Cleaned up comments in mod_cgi.c [Robert Thau]
11287 Changes with Apache 0.8.11 24 Aug 1995
11289 *) Wildcard <Directory> specifications work. [Robert Thau]
11291 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
11293 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
11294 the file being requested itself, in addition to the directories leading
11295 up to it. [Robert Thau]
11297 *) Logs access failures due to symlink checks or invalid client address
11298 in the error log [Roy Fielding, Robert Thau]
11300 *) Symlink checks deal correctly with systems where lstat of
11301 "/path/to/some/link/" follows the link. [Thau, Fielding]
11303 *) Doesn't reset DirectoryIndex to 'index.html' when
11304 other directory options are set in a .htaccess file. [Robert Thau]
11306 *) Clarified init code and nuked bogus warning in mod_access.c
11307 [Florent Guillaume]
11309 *) Corrected several directives in sample srm.conf
11310 --- includes corrections to directory indexing icon-related directives
11311 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
11312 icons for encodings right, and turning on AddEncoding by default).
11315 *) Corrected descriptions of args to AddIcon and AddAlt in command table
11318 *) INSTALL & README mention "contributed modules" directory [Brian
11321 *) Fixed English in the license language... "for for" --> "for".
11324 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
11325 mod_alias.c, merging it almost completely with handling of Alias, and
11326 adding a 'notes' field to the request_rec which allows the CGI module
11327 to discover whether the Alias module has put this request through
11328 ScriptAlias (which it needs to know for back-compatibility, as the old
11329 NCSA code did not check Options ExecCGI in ScriptAlias directories).
11332 Changes with Apache 0.8.10 18 Aug 1995
11334 *) AllowOverride applies to the named directory, and not just
11335 subdirectories. [David Robinson]
11337 *) Do locking for accept() exclusion (on systems that need it)
11338 using a special file created for the purpose in /usr/tmp, and
11339 not the error log; using the error log causes real problems
11340 if it's NFS-mounted; this is known to be the cause of a whole
11341 lot of "server hang" problems with Solaris. [David Robinson;
11342 thanks to Merten Schumann for help diagnosing the problem].
11344 Changes with Apache 0.8.9 12 Aug 1995
11346 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
11348 *) Nested includes see environment variables of the including document,
11349 for NCSA bug-compatibility (some sites have standard footer includes
11350 which try to print out the last-modified date). [Eric Hagberg/Robert
11353 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
11354 URI as a CGI script, even if it would have been treated as something
11355 else if requested directly, for NCSA back-compatibility. (Note that
11356 this means that people who know the name of the script can see the
11357 code just by asking for it). [Robert Thau]
11359 *) New version of dbmmanage script included in support directory as
11362 *) Check if scoreboard file couldn't be opened, and say so, rather
11363 then going insane [David Robinson]
11365 *) POST to CGI works on A/UX [Jim Jagielski]
11367 *) AddIcon and AddAlt commands work properly [Rob Hartill]
11369 *) NCSA server push works properly --- the Arena bug compatibility
11370 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
11371 if you still want the workaround). [Rob Hartill]
11373 *) If client didn't submit any Accept-encodings, ignore encodings in
11374 content negotiation. (NB this will all have to be reworked anyway
11375 for the new HTTP draft). [Florent Guillaume]
11377 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
11379 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
11381 *) Give Redirect priority over Alias, for NCSA bug compatibility
11384 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
11385 paralleling earlier bug fix for CGI [David Robinson]
11387 *) If DBM auth is improperly configured, report a server error and don't
11390 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
11391 it seems to work well enough without it (even in a 10 hits/sec
11392 workout), and the overhead for the locking under A/UX is
11393 alarmingly high (though it is very low on other systems).
11394 [Eric Hagberg, Jim Jagielski]
11396 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
11398 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
11399 Behlendorf/Eric Hagberg]
11401 *) More improvements to default Configuration for A/UX [Jim Jagielski]
11403 *) Compiles clean on NEXT [Rob Hartill]
11405 *) Compiles clean on SGI [Robert Thau]
11407 Changes with Apache 0.8.8 08 Aug 1995
11409 *) SunOS library prototypes now never included unless explicitly
11410 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
11411 people using GNU libc on SunOS are screwed by prototypes for the
11414 (Those who wish to compile clean with gcc -Wall on a standard
11415 SunOS setup need the prototypes, and may obtain them using
11416 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
11417 with nonstandard libraries are presumably competent to make their
11420 *) Strips trailing '/' characters off both args to the Alias command,
11421 to make 'Alias /foo/ /bar/' work.
11423 Changes with Apache 0.8.7 03 Aug 1995
11425 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
11426 [reported by David Robinson]
11428 *) Compiles clean on OSF/1 [David Robinson]
11430 *) Added some of the more recent significant changes (AddLanguage stuff,
11431 experimental LogFormat support) to CHANGES file in distribution root
11434 Changes with Apache 0.8.6 02 Aug 1995
11436 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
11437 (If you actually wanted a conditional GET which bypassed the cache, you
11438 couldn't get it). [Reported by Roy Fielding]
11440 *) Properly terminate headers on '304 Not Modified' replies to conditional
11441 GETs --- no browser we can find cares much, but the CERN proxy chokes.
11442 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
11444 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
11446 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
11447 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
11448 and older versions don't set the __SUNPRO_C preprocessor variable). On
11449 all other systems, these are never used anyway. [Reported by Mark Cox].
11451 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
11453 Changes with Apache 0.8.5 01 Aug 1995
11455 *) Added last-minute configurable log experiment, as optional module
11457 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
11458 properly. (One-line fix to http_protocol.c).
11460 *) Work around bogus behavior when reloading from Netscape.
11461 It's Netscape's bug --- for some reason they expect a request with
11462 If-modified-since: to not function as a conditional GET if it also
11463 comes with Pragma: no-cache, which is way out of line with the HTTP
11464 spec (according to Roy Fielding, the redactor).
11466 *) Added parameter to set maximum number of server processes.
11468 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
11471 *) IdentityCheck bugfix [Chuck Murcko].
11473 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
11475 *) More sample config file corrections; add extension to AddType for
11476 *.asis, move AddType generic description to its proper place, and
11477 fix miscellaneous typos. [ Alexei Kosut ]
11479 *) Deleted the *other* reference to the regents from the Berkeley
11480 legal disclaimer (everyplace).
11482 *) Nuked Shambhala name from src/README; had already cleaned it out
11483 of everywhere else.
11485 Changes with Apache 0.8.4
11487 *) Changes to server-pool management parms --- renamed current
11488 StartServers to MinSpareServers, created separate StartServers
11489 parameter which means what it says, and renamed MaxServers to
11490 MaxSpareServers (though the old name still works, for NCSA 1.4
11491 back-compatibility). The old names were generally regarded as
11492 too confusing. Also altered "docs" in sample config files.
11494 *) More improvements to default config files ---
11495 sample directives (commented out) for XBitHack, BindAddress,
11496 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
11497 defaults, AddTypes for send-as-is and imagemap magic types, and
11498 improvements to samples for DirectoryIndex [Alexei Kosut]
11500 *) Yet more improvements to default config files --- changes to
11501 Alexei's sample AddLanguage directives, and sample LanguagePriority
11502 [ Florent Guillaume ]
11504 *) Set config file locations properly if not set in httpd.conf
11507 *) Don't escape URIs in internal redirects multiple times; don't
11508 do that when translating PATH_INFO to PATH_TRANSLATED either.
11511 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
11513 Changes with Apache 0.8.3
11515 *) Edited distribution README to *briefly* summarize installation
11516 procedures, and give a pointer to the INSTALL file in the src/
11519 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
11520 recent NCSA distributions.
11522 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
11523 exist for the same directory, use both and don't segfault. [Reported
11526 *) Proper makefile dependencies [David Robinson]
11528 *) Note (re)starts in error log --- reported by Rob Hartill.
11530 *) Only call no2slash() after get_path_info() has been done, to
11531 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
11532 reported by Andrew Wilson, though this one is probably a real bug]
11534 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
11535 dump core when Referer is not supplied. [Randy Terbush]
11537 *) Lightly edited sample config files to refer people to our documentation
11538 instead of NCSA's, and to list Rob McCool as *original* author (also
11539 deleted his old, and no doubt non-functional email address). Would be
11540 nice to have examples of new features...
11542 Changes with Apache 0.8.2 19 Jul 1995
11544 *) Added AddLanuage code [Florent Guillaume]
11546 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
11548 *) All sorts of problems when MultiViews finds a directory. It would
11549 be nice if mod_dir.c was robust enough to handle that, but for now,
11550 just punt. [reported by Brian Behlendorf]
11552 *) Wait for all children on restart, to make sure that the old socket
11553 is gone and we can reopen it. [reported by Randy Terbush]
11555 *) Imagemap module is enabled in default Configuration
11557 *) RefererLog and UserAgentLog modules properly default the logfile
11560 *) Mark Cox's mod_cookies added to the distribution as an optional
11561 module (commented out in the default Configuration, and noted as
11562 an experiment, along with mod_dld). [Mark Cox]
11564 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
11566 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
11568 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
11570 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
11573 Changes with Apache 0.8.1
11575 *) New imagemap module [Randy Terbush]
11577 *) Replacement referer log module with NCSA-compatible RefererIgnore
11578 [Matthew Gray again]
11580 *) Don't mung directory listings with very long filenames.
11581 [Florent Guillaume]
11583 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
11585 *) New config script. See INSTALL for info. [Robert Thau]
11587 *) Scoreboard mechanism for regulating the number of extant server
11588 processes. MaxServers and StartServers defaults are the same as
11589 for NCSA, but the meanings are slightly different. (Actually,
11590 I should probably lower the MaxServers default to 10).
11592 Before asking for a new connection, each server process checks
11593 the number of other servers which are also waiting for a
11594 connection. If there are more than MaxServers, it quietly dies
11595 off. Conversely, every second, the root, or caretaker, process
11596 looks to see how many servers are waiting for a new connection;
11597 if there are fewer than StartServers, it starts a new one. This
11598 does not depend on the number of server processes already extant.
11599 The accounting is arranged through a "scoreboard" file, named
11600 /tmp/htstatus.*, on which each process has an independent file
11601 descriptor (they need to seek without interference).
11603 The end effect is that MaxServers is the maximum number of
11604 servers on an *inactive* server machine, but more will be forked
11605 off to handle unusually heavy loads (or unusually slow clients);
11606 these will die off when they are no longer needed --- without
11607 reverting to the overhead of full forking operation. There is a
11608 hard maximum of 150 server processes compiled in, largely to
11609 avoid forking out of control and dragging the machine down.
11610 (This is arguably too high).
11612 In my server endurance tests, this mechanism did not appear to
11613 impose any significant overhead, even after I forced it to put the
11614 scoreboard file on a normal filesystem (which might have more
11615 overhead than tmpfs). [Robert Thau]
11617 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
11620 *) Read .htaccess files even in directory with <Directory> section.
11621 (Former incompatibility noted on mailing list, now fixed). [Robert
11624 *) "HEAD /" gives the client a "Bad Request" error message, rather
11625 than trying to send no body *and* no headers. [Cliff Skolnick].
11627 *) Don't produce double error reports for some very obscure cases
11628 mainly involving auth configuration (the "all modules decline to
11629 handle" case which is a sure sign of a server bug in most cases,
11630 but also happens when authentication is badly misconfigured).
11633 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
11634 it's *for*, and this sort of thing really shouldn't be cluttering
11635 up the Makefile). [Robert Thau]
11637 *) Incidental code cleanups in http_main.c --- stop dragging
11638 sa_client around; just declare it where used. [Robert Thau]
11640 *) Another acc-related fix. (It doesn't like const char
11641 in some places...). [Mark Cox]
11643 Changes with Shambhala 0.6.1 13 Jul 1995
11645 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
11646 Also, fixed auth typo in http_protocol.c unmasked by this fix.
11648 *) Compiles clean with acc on SunOS [Paul Sutton]
11650 *) Reordered modules in modules.c so that Redirect takes priority
11651 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
11652 believe it or not, he has an actual site with a ScriptAlias and
11653 a Redirect declared for the *exact same directory*. Even *my*
11654 compatibility fetish wouldn't motivate me to fix this if the fix
11655 required any effort, but it doesn't, so what the hey.
11657 *) Fixed to properly default several server_rec fields for virtual
11658 servers from the corresponding fields in the main server_rec.
11659 [Cliff Skolnick --- 'port' was a particular irritant].
11661 *) No longer kills off nph- child processes before they are
11662 finished sending output. [Matthew Gray]
11664 Changes with Shambhala 0.6.0 10 Jul 1995
11666 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
11667 the connection to the client in an "aborted" state, but otherwise
11668 allow whatever handlers are running to clean up. hard_timeout()s
11669 abort the request in progress completely; anything not tied to some
11670 resource pool cleanup will leak. They're still around because I
11671 haven't yet come up with a more elegant way of handling
11672 timeouts when talking to something that isn't the client. The
11673 default_handler and the dir_handler now use soft timeouts, largely
11674 so I can test the feature. [Robert Thau]
11676 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
11677 the case of log handlers dying prematurely is probably handled VERY
11678 gracelessly at this point, and if the logger stops reading input,
11679 the server will hang. (It is known to correctly restart the
11680 logging process on server restart; this is (should be!) going through
11681 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
11682 script). [Robert Thau]
11684 *) asis files supported (new module). [Robert Thau]
11686 *) IdentityCheck code is compiled in, but has not been tested. (I
11687 don't know anyone who runs identd). [Robert Thau]
11689 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
11690 came in with the request, for NCSA bug-compatibility. [Robert Thau]
11692 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
11694 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
11695 as timeouts are not in scope. [Robert Thau]
11697 *) quoted-string args in config files now handled correctly (doesn't drop
11698 the last character). [Robert Thau; reported by Randy Terbush]
11700 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
11701 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
11703 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
11704 default default type); the former default default behavior when all
11705 type-checkers defaulted had been a core dump. [Paul Sutton]
11707 *) Copy filenames out of the struct dirent when indexing
11708 directories. (On Linux, readdir() returns a pointer to the same
11709 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
11711 Changes with Shambhala 0.5.3 [not released]
11713 *) Default response handler notes "file not found" in the error log,
11714 if the file was not found. [Cliff Skolnick].
11716 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
11717 code no longer sets up bogus PATH_INFO which fakes out the directory
11718 handler). [Cliff Skolnick]
11720 Changes with Shambhala 0.5.2 06 Jul 1995
11722 *) Changes to http_main.c --- root server no longer plays silly
11723 games with SIGCHLD, and so now detects and replaces dying
11724 children. Child processes just die on SIGTERM, without taking
11725 the whole process group with them. Potential problem --- if any
11726 child process refuses to die, we hang in restart.
11727 MaxRequestsPerChild may still not work, but it certainly works
11728 better than it did before this! [Robert Thau]
11730 *) mod_dir.c bug fixes: ReadmeName and HeaderName
11731 work (or work better, at least); over-long description lines
11732 properly terminated. [Mark Cox]
11734 *) http_request.c now calls unescape_url() more places where it
11735 should [Paul Sutton].
11737 *) More directory handling bugs (reported by Cox)
11738 Parent Directory link is now set correctly. [Robert Thau]
11740 Changes with Shambhala 0.5.1 04 Jul 1995
11742 *) Generalized cleanup interface in alloc.c --- any function can be
11743 registered with alloc.c as a cleanup for a resource pool;
11744 tracking of files and file descriptors has been reimplemented in
11745 terms of this interface, so I can give it some sort of a test.
11748 *) More changes in alloc.c --- new cleanup_for_exec() function,
11749 which tracks down and closes all file descriptors which have been
11750 registered with the alloc.c machinery before the server exec()s a
11751 child process for CGI or <!--#exec-->. CGI children now get
11752 started with exactly three file descriptors open. Hopefully,
11753 this cures the problem Rob H. was having with overly persistent
11754 CGI connections. [Robert Thau]
11756 *) Mutual exclusion around the accept() in child_main() --- this is
11757 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
11758 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
11759 This uses fcntl(F_SETLK,...) on the error log descriptor because
11760 flock() on that descriptor won't work on systems which have BSD
11761 flock() semantics, including (I think) Linux 1.3 and Solaris.
11763 This does work on SunOS (when the server is idle, only one
11764 process in the pool is waiting on accept()); it *ought* to work
11765 on the other systems. [Robert Thau]
11767 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
11769 *) sizeof(*sa_client) bugfix from [Rob Hartill]
11771 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
11773 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
11774 be unnecessary if I go to the revised timeout-handling scheme).
11777 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
11778 string) even if none came in with the request. [Robert Thau]
11780 *) CHANGES file added to distribution ;-).
11782 Changes with Shambhala 0.4.5
11784 *) mod_dld --- early dynamic loading support [rst]
11785 *) Add wildcard content handlers for XBITHACK; default_hander now
11786 invoked with that mechanism (as a handler hanging off mod_core) [rst]
11787 *) XBITHACK supported as a wildcard content-handler, and
11788 configurable at run-time (not just at compile time, as in the
11789 "patchy server" releases) [rst]
11791 Changes with Shambhala 0.4.4 30 Jun 1995
11793 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
11794 *) Handle Addtype x/y .z [rst, reported by Cox]
11796 Changes with Shambhala 0.4.3
11798 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
11799 synonymous [rst, terbush]
11801 Changes with Shambhala 0.4.1 28 Jun 1995
11803 *) First-cut virtual host implementation; some refit in the config
11804 reading code, and log management, was necessary to support this [rst]
11805 *) Sub-pool machinery, originally added to avoid excessive storage
11806 allocation on listings of large directories (which turned out to
11807 be the problem that the 0.3 storage accounting was added to
11808 find). Subrequests and mod_dir changed to use subpools. [rst]
11809 *) More memory debugging --- free list consistency checks. [rst]
11810 *) Added err_headers to request_rec, with support elsewhere [rst]
11811 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
11813 Changes with Shambhala 0.3 19 Jun 1995
11815 *) Switch ONE_PROCESS to a runtime command-line option (-X)
11816 *) Don't compile in mod_ai_backcompat by default
11817 *) Switch name of server from Apache to Shambhala in Makefile
11818 *) Add some accounting routines to track memory usage in the pools,
11821 Changes with Shambhala 0.2
11823 *) Set DOCUMENT_ROOT CGI variable
11824 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
11825 *) Add critical section protection to handling of cleanup structures
11827 *) Significant code reorg within the server core to group related
11828 functions together [rst]
11829 *) Correctly handle clients that hang up before sending any request
11831 *) Replace dying child processes. [rst]
11833 Changes with Shambhala 0.1 12 Jun 1995
11835 Major rewrite of the pre-existing "patchy server" codebase, by
11836 Robert Thau (rst). Significant portions of the server code, such
11837 as configuration-file handling and HTTP authentication support,
11838 were ripped out and rewritten from scratch. Code that was not
11839 completely rewritten was significantly altered.
11841 Major changes with this release include:
11843 *) Introduction of the module API; in request handling, the central
11844 machinery just dispatches to various modules, which actually do
11845 most of the work. Configuration handling is similar --- modules
11846 declare their own commands, and the central machinery just
11847 dispatches to them.
11849 API features from shambhala/0.1 were substantially unchanged in
11850 Apache 1.0 and 1.1. (1.0 API features not yet present in this
11851 release, such as wildcard handlers and subpools, were added in
11852 subsequent Shambhala releases, and were also generally rst's
11855 *) This release included the following modules:
11857 mod_access (access control --- allow and deny directives),
11858 mod_alias (Alias and Redirect commands),
11859 mod_auth (straight HTTP authentication, based on flat-files)
11860 mod_auth_dbm (same, with dbm files)
11861 mod_cgi (CGI scripts and, in this release, ScriptAlias)
11862 mod_common_log (CLF access logs; later renamed mod_log_common)
11863 mod_dir (directory indexing)
11864 mod_include (server-side includes)
11865 mod_mime (AddType directives)
11866 mod_negotiation (content negotiation)
11867 mod_userdir (support for users' public_html directories)
11869 It also included a mod_ai_backcompat, which was a private hack
11870 for back-compatibility with rst's own AI-lab servers.
11872 All of these modules were substantially complete, and functional
11873 or nearly so (a few, which implemented features not in use at
11874 Thau's site, required patches of a few lines).
11876 *) sub-request machinery, to allow modules to determine how other
11877 modules would assign MIME types to a given file, or optionally
11878 serve its content (this is heavily used by mod_dir, mod_include
11879 and mod_negotiation).
11881 *) Resource pool system for keeping track of memory allocated and
11882 files opened in service of a particular request. Much of the
11883 code in the modules (when they weren't rewrites) was adjusted to
11884 replace a pervasive convention of using fixed-size buffers on
11885 the stack with an equally pervasive convention of using memory
11886 allocated with palloc().
11888 *) Reorganization of data structures associated with a given
11889 request to eliminate use of global variables and the troublesome
11890 unmunge_name function (used in NCSA and early Apache releases to
11891 attempt to determine the URI which mapped to a given filename
11892 --- a difficult proposition, given that it is easy to produce
11893 setups in which multiple URIs map to the same file).
11895 *) Source files renamed and rearranged
11897 *) Very simple pre-forking behavior --- parent process forked off a
11898 fixed number of children, and then just waited for SIGHUP.
