1 Changes with Apache 2.0.37
3 *) Allow RewriteMap prg:'s to take command-line arguments. PR 8464.
4 [James Tait <JTait@wyrddreams.demon.co.uk>]
6 *) Correctly return 413 when an invalid chunk size is given on
7 input. Also modify ap_discard_request_body to not do anything
8 on sub-requests or when the connection will be dropped.
11 *) Fix the TIME_* SSL var lookups to be threadsafe. PR 9469.
14 *) Ensure that apr_brigade_write() flushes in all of the cases that
15 it should to avoid conditions in some modules that could cause
16 large amounts of data to be buffered. [Cliff Woolley]
18 *) Fix problem where mod_cache/mod_disk_cache was incorrectly
19 stripping the content_type from cached responses.
22 *) apachectl passes through any httpd options. Note: apachectl
23 should be used in preference to httpd since it ensures that any
24 appropriate environment variables have been set up.
27 *) Fix the combination of mod_cgid, mod_setuexec, and mod_userdir.
28 PR 7810 [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]
30 *) Fix suexec execution of CGI scripts from mod_include.
31 PR 7791, 8291 [Colm MacCarthaigh <colmmacc@redbrick.dcu.ie>]
33 *) Fix segfaults at startup on some platforms when mod_auth_digest,
34 mod_suexec, or mod_ssl were used as DSO's due to the way they
35 were tracking the current init phase since DSO's get completely
36 unloaded and reloaded between phases. PR 9413.
37 [Tsuyoshi Sasamoto <nazonazo@super.win.ne.jp>, Brad Nicholes]
39 *) Fix mod_include's handling of regular expressions in
40 "<!--#if" directives [Julius Gawlas <julius_gawlas@hp.com>]
42 *) Fix the worker MPM deadlock problem [Brian Pane]
44 *) Modify the module documentation to allow for translations.
45 [Yoshiki Hayashi, Joshua Slive]
47 *) Fix a file permissions problem which prevented mod_disk_cache
48 from working on Unix. [Jeff Trawick]
50 *) Add "-k start|restart|graceful|stop" support to httpd for the Unix
51 MPMs. These have semantics very similar to the old apachectl
52 commands of the same name. [Justin Erenkrantz, Jeff Trawick]
54 *) Make sure that the runtime dir is created by make install.
55 PR 9233. [Jeff Trawick]
57 *) Fix an unusual set of ./configure arguments that could cause
58 mod_http to be built as a DSO, which it currently doesn't
60 [Cliff Woolley, Robin Johnson <robbat2@orbis-terrarum.net>]
62 *) Win32: Fix bug in apr_sendfile() that caused incorrect operation
63 of the %X, %b and %B logformat options. PR 8253, 8996.
66 *) If content-encoding is already present, do not run deflate (PR 9222)
67 [Kazuhisa ASADA <kaz@asada.sytes.net>]
69 *) The APLOG_NOERRNO flag to ap_log_[r]error() is now deprecated.
70 It is currently ignored and it will be removed in a future release
71 of Apache. [Jeff Trawick]
73 *) Removed documentation references to the no-longer-supported
74 "make certificate" feature of mod_ssl for Apache 1.3.x. Test
75 certificates, if truly desired, can be generated using openssl
76 commands. PR 8724. [Cliff Woolley]
78 *) Remove SSLLog and SSLLogLevel directives in favor of having
79 mod_ssl use the standard ErrorLog directives. [Justin Erenkrantz]
81 *) OS/390: LIBPATH no longer has to be manually uncommented in
82 envvars to get apachectl to set up httpd properly. [Jeff Trawick]
84 *) mod_isapi: All mod_isapi directives, excluding ISAPICacheFile,
85 may now be specified to the <File/Directory > container, rather
86 than by vhost. [William Rowe]
88 *) mod_isapi: Experimental support for faux async support for ISAPI
89 modules. [William Rowe]
91 *) mod_isapi: Major refactoring of the code to rely on apr internals
92 rather than MS APIs (using our own mod_isapi.h headers for ISAPI
93 symbol definitions.) [William Rowe]
95 *) mod_isapi: Fixed the return string length from GetServerVariable
96 callback, it was not including the trailing null in the consumed
97 buffer size. This was particularly bad for Delphi 6.0 users.
98 PR 8934 [Sebastian Hantsch <sebastian.hantsch@gmx.de>]
100 *) Fixed Win32 builds for Microsoft VisualStudio 7.0 (.net).
103 *) Make apxs look in the correct directory for envvars. It was
104 broken when sbindir != bindir. PR 8869
105 [Andreas Sundström <sunkan@zappa.cx>]
107 *) Fix mod_deflate corruption when using multiple buckets. PR 9014.
108 [Asada Kazuhisa <kaz@asada.sytes.net>]
110 *) Performance enhancements for access logger when using
111 default timestamp formatting [Brian Pane]
113 *) Added EnableMMAP config directive to enable the server
114 administrator to disable memory-mapping of delivered files
115 on a per-directory basis. [Brian Pane]
117 *) Performance enhancements for mod_setenvif [Brian Pane]
119 *) Fix a mod_ssl build problem on OS/390. [Jeff Trawick]
121 *) Fixed If-Modified-Since on Win32, which would give false positives
122 because of the sub-second resolution of file timestamps on that
123 platform. [Cliff Woolley]
125 *) Reverse the hook ordering for mod_userdir and mod_alias so
126 that Alias/ScriptAlias will override Userdir. PR 8841
129 *) Move mod_deflate out of experimental and into filters.
132 *) Get proxy CONNECT basically working. [Jeff Trawick]
134 *) Fix mod_rewrite hang when APR uses SysV Semaphores and
135 RewriteLogLevel is set to anything other than 0. PR: 8143
136 [Aaron Bannert, Cliff Woolley]
138 *) Fix byterange requests from returning 416 when using dynamic data
139 (such as filters like mod_include). [Justin Erenkrantz]
141 *) Allow mod_rewrite's set of "int:" internal RewriteMap functions
142 to be extended by third-party modules via an optional function.
143 [Tahiry Ramanamampanoharana <nomentsoa@hotmail.com>, Cliff Woolley]
145 *) Fix mod_include expression parser's handling of unquoted strings
146 followed immediately by a closing paren. PR 8462. [Brian Pane]
148 *) Remove autom4te.cache in 'make distclean'.
149 [Thom May <thom@planetarytramp.net>]
151 *) Fix generated httpd.conf to respect layout for LoadModule lines.
152 PR 8170. [Thom May <thom@planetarytramp.net>]
154 *) Win32: During a graceful restart, threads in the new process
155 were accessing scoreboard slots still in use by active threads in
156 the the old process. [Bill Stoddard]
158 Changes with Apache 2.0.36
160 *) Fix some minor formatting issues with ab. Part of this is
161 in reference to PR 8544, the rest I noticed while testing
162 the PR fix. [Paul J. Reder]
164 *) Fix a case where an invalid pass phrase is entered and an
165 error message is given, but the prompt is not shown again.
166 This left the user in an ambiguous state. PR 8320 [Paul J. Reder]
168 *) Close sockets on worker MPM when doing a graceless restart.
171 *) Reverted a minor optimization in mod_ssl.c that used the vhost ID
172 as the session id context rather that a MD5 hash of that vhost ID,
173 because it caused very long vhost id's to be unusable with mod_ssl.
174 PR 8572. [Cliff Woolley]
176 *) Fix the link to the description of the CoredumpDirectory
177 directive in the server-wide document. PR 8643. [Jeff Trawick]
179 *) Fixed SHMCB session caching. [Aaron Bannert, Cliff Woolley]
181 *) Synced with remaining changes from mod_ssl 2.8.8-1.3.24:
182 - Avoid SIGBUS on sparc machines with SHMCB session caches
183 - Allow whitespace between the pipe and the name of the
184 program in SSLLog "| /path/to/program". [Cliff Woolley]
186 *) Introduce mod_ext_filter and mod_deflate experimental modules
187 to the Win32 build (zlib sources must be in srclib\zlib.)
190 *) Changes to the worker MPM's queue management and thread
191 synchronization code to reduce mutex contention [Brian Pane]
193 *) Don't install *.in configuration files since we already install
194 *-std.conf files. [Aaron Bannert]
196 *) Many improvements to the threadpool MPM. [Aaron Bannert]
198 *) Fix subreqs that are promoted via fast_redirect from having invalid
199 frec->r structures. This would cause subtle errors later on in
200 request processing such as seen in PR 7966. [Justin Erenkrantz]
202 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
204 *) Modify the worker MPM to not accept() new connections until
205 there is an available worker thread. This prevents queued
206 connections from starving for processing time while long-running
207 connections were hogging all the available threads. [Aaron Bannert]
209 *) Convert the worker MPM's fdqueue from a LIFO back into a FIFO.
212 *) Get basic HTTP proxy working on EBCDIC machines. [Jeff Trawick]
214 *) Allow mod_unique_id to work on systems with no IPv4 address
215 corresponding to their host name. [Jeff Trawick]
217 *) Fix suexec behavior with user directories. PR 7810.
218 [Colm <colmmacc@redbrick.dcu.ie>]
220 *) Reject a blank UserDir directive since it is ambiguous. PR 8472.
223 *) Make mod_mime use case-insensitive matching when examining
224 extensions on all platforms. PR 8223. [Justin Erenkrantz]
226 *) Add an intelligent error message should no proxy submodules be
227 valid to handle a request. PR 8407 [Graham Leggett]
229 *) Major improvements in concurrent processing for AB by enabling
230 non-blocking connect()s and preventing APR from doing blocking
231 read()s. Also implement fatal error checking for apr_recv().
234 *) Fix Win32 NTFS Junctions (symlinks). PR 8014 [William Rowe]
236 *) Fix Win32 'short name' aliases in httpd.conf directives.
237 PR 8009 [William Rowe]
239 *) Fix generation of default httpd.conf when the layout paths are
240 disjoint. PR 7979, 8227. [Justin Erenkrantz]
242 *) Swap downgrade-1.0 and force-response-1.0 conditional checks so
243 that downgraded responses can have force-response. PR 8357.
246 *) Fix perchild MPM so that it can be configured with the move to the
247 experimental directory. [Scott Lamb <slamb@slamb.org>]
249 *) Fix perchild MPM so that it uses ap_gname2id for groups instead of
250 ap_uname2id. [Scott Lamb <slamb@slamb.org>]
252 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
254 *) [Security] Added the APLOG_TOCLIENT flag to ap_log_rerror() to
255 explicitly tell the server that warning messages should be sent
256 to the client in addition to being recorded in the error log.
257 Prior to this change, ap_log_rerror() always sent warning
258 messages to the client. In one case, a faulty CGI script caused
259 the server to send a warning message to the client that contained
260 the full path to the CGI script. This could be considered a
261 minor security exposure. [Bill Stoddard]
263 *) mod_autoindex output when SuppressRules was specified would
264 omit the first carriage return so the first item in the list
265 would appear to the right of the column headings instead of
266 underneath them. PR 8016 [David Shane Holden <dpejesh@yahoo.com>]
268 *) Moved the call to apr_mmap_dup outside the error branch so
269 that it would actually get called. This fixes a core dump
270 at init everytime you use the MMapFile directive. PR 8314
273 *) Trigger an error when a LoadModule directive attempts to
274 load a module which is built-in. This is a common error when
275 switching from a DSO build to a static build. [Jeff Trawick]
277 *) Change instdso.sh to use libtool --install everywhere and then
278 clean up some stray files and symlinks that libtool leaves around
279 on some platforms. This gets subversion building properly since
280 it needed a re-link to be performed by libtool at install time,
281 and the old instdso.sh logic to simply cp the DSO didn't handle
282 that requirement. [Sander Striker]
284 *) Allow VPATH builds to succeed when configured from an empty
285 directory. [Thom May <thom@planetarytramp.net>]
287 *) Fix 'control reaches end of non-void function' warning in
288 server/log.c. [Ben Collins-Sussman <sussman@collab.net>]
290 *) Perchild MPM is now correctly deemed as experimental and is now
291 located in server/mpm/experimental. [Justin Erenkrantz]
293 *) Fix segfault in mod_mem_cache when garabge collecting an expired
294 cache entry. [Bill Stoddard]
296 *) Introduced -E startup_logfile_name option to httpd to allow admins
297 to begin logging errors immediately. This provides Win32 users
298 an alternative to sending startup errors to the event viewer, and
299 allows other daemon tool authors an alternative to logging to stderr.
302 *) Fix subreqs with non-defined Content-Types being served improperly.
305 *) Merge in latest GNU config.guess and config.sub files. PR 7818.
308 *) Move 100 - Continue support to the HTTP_IN filter so that filters
309 are guaranteed to support 100 - Continue logic without any
310 intervention. [Justin Erenkrantz]
312 *) Add HTTP chunked input trailer support. [Justin Erenkrantz]
314 *) Rename and export get_mime_headers as ap_get_mime_headers.
317 *) Allow empty Host: header arguments. PR 7441. [Justin Erenkrantz]
319 *) Properly substitute sbindir as httpd's location in apachectl. PR 7840.
320 [Andreas Hasenack <andreas@netbank.com.br>]
322 *) Allow Win32 shebang scripts to follow the path (or omit the .exe
323 suffix from the shebang command), and allow ScriptInterpreterSource
324 Registry or RegistryStrict to override shebang lines, as 1.3 did.
325 PR 8004 [William Rowe]
327 *) worker MPM: Fix a situation where a child exited without releasing
328 the accept mutex. Depending on the OS and mutex mechanism this
329 could result in a hang. [Jeff Trawick]
331 *) Update the instructions for how to get started with mod_example.
334 *) Fix PidFile to default to rel_runtimedir instead of
335 rel_logfiledir. PR 7841. [Andreas Hasenack <andreas@netbank.com.br>]
337 *) Win32: Fix problem that caused rapid performance degradation
338 when number of connecting clients exceeded ThreadsPerChild.
341 *) Fixed a segfault parsing large SSIs on non-mmap systems.
344 *) Proxy was bombing out every second keepalive request, caused by a
345 stray CRLF before the second response's status line. Proxy now
346 tries to read one more line if it encounters a CRLF where it
347 expected a status. PR 10010 [Graham Leggett]
349 *) Deprecated the apr_lock.h API. Please see the following files
350 for the improved thread and process locking and signaling:
351 apr_proc_mutex.h, apr_thread_mutex.h, apr_thread_rwlock.h,
352 apr_thread_cond.h, and apr_global_mutex.h. [Aaron Bannert]
354 *) Change mod_status to use scoreboard accessor functions so it can
355 be used in any MPM without having to be recompiled.
356 [Ryan Morgan <rmorgan@covalent.net>]
358 *) Fix parsing of some AP_DECLARE_DATA declarations so that the filter
359 handle declarations are recognized. This fixes problems loading
360 mod_autoindex on some platforms. [Brian Havard]
362 *) add optional fixup hook to proxy [Daniel Lopez <daniel@covalent.net>]
364 *) Remind the admin about the User and Group directives when we are
365 unable to set permissions on a semaphore. PR 7812 [Jeff Trawick]
367 *) fix possible compilation problem in ssl_engine_kernel.c. PR 7802
370 *) fix possible infinite loop in mod_ssl triggered by certain
371 netscape clients [Doug MacEachern]
373 *) fix ProxyPass when frontend is https and backend is http
376 *) Add DASL support to mod_dav
377 [Sung Kim <hunkim@cse.ucsc.edu>]
379 Changes with Apache 2.0.35
381 *) mod_rewrite: updated to use the new APR global mutex type.
384 *) Fixes for mod_include errors on boundary conditions in which
385 "<!--#" occurs at the very end of a bucket
386 [Paul Reder, Brian Pane]
388 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
389 cause the Apache parent process to run in the foreground (similar to
390 -DNO_DETACH except that it doesn't switch session ids).
393 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
394 for those platforms that support it. If using the default
395 implementation, this is between pthread and sysvsem in priority.
396 This implies it's the new default for Darwin. [Jim Jagielski]
398 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
399 environment variables in the envvars file. [Jeff Trawick]
401 *) worker MPM: Don't create a listener thread until we have a worker
402 thread. Otherwise, in situations where we'll have to wait a while
403 to take over scoreboard slots from a previous generation, we'll be
404 accepting connections we can't process yet. [Jeff Trawick]
406 *) Allow worker MPM to build on systems without pthread_kill().
407 [Pier Fumagalli, Jeff Trawick]
409 *) Prevent ap_add_output_filters_by_type from being called in
410 ap_set_content_type if the content-type hasn't changed.
413 *) Performance: implemented the bucket allocator made possible by the
414 API change in 2.0.34. [Cliff Woolley]
416 *) Don't allow initialization to succeed if we can't get a socket
417 corresponding to one of the Listen statements. [Jeff Trawick]
419 Changes with Apache 2.0.34
421 *) Allow all Perchild directives to accept either numerical UID/GID
422 or logical user/group names. [Scott Lamb <slamb@slamb.org>]
424 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
426 *) implement ssl proxy to support ProxyPass / https:// and the
427 SSLProxy* directives [Doug MacEachern]
429 *) Update mod_cgid to not do single-byte socket reads for CGI headers
432 *) Made AB's use of the Host: header rfc2616 compliant
433 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
435 *) The old, legacy (and unused) code in which the scoreboard was totally
436 and completely contained in a file (SCOREBOARD_FILE) has been
437 removed. This does not affect scoreboards which are *mapped* to
438 files using named-shared-memory. [Jim Jagielski]
440 *) Change bucket brigades API to allow a "bucket allocator" to be
441 passed in at certain points. This allows us to implement freelists
442 so that we can stop using malloc/free so frequently.
443 [Cliff Woolley, Brian Pane]
445 *) Add support for macro expansion within the variable names in
446 <!--#echo--> and <!--#set--> directives [Brian Pane]
448 *) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
450 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
453 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
454 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
456 *) Add a new parameter to the quick_handler hook to instruct
457 quick handlers to optionally do a lookup rather than actually
458 serve content. This is the first of several changes required fix
459 several problems with how quick handlers work with subrequests.
462 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
464 *) [APR-related] The ordering of the default accept mutex method has
465 been changed to better match what's done in Apache 1.3. The ordering
466 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
469 *) Ensure that the build/ directory is created when using VPATH.
472 *) Add some popular types to the mime magic file. PR 7730.
473 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
475 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
477 *) When a proxied site was being served, Apache was replacing
478 the original site Server header with it's own, which is not
479 allowed by RFC2616. Fixed. [Graham Leggett]
481 *) Fix a mod_cgid problem that left daemon processes stranded
482 in some server restart scenarios. [Jeff Trawick]
484 *) Added exp_foo and rel_foo variables to config_vars.mk for
485 all Apache and Autoconf path variables (like --sysconfdir,
486 --sbindir, etc). exp_foo is the "expanded" version, which means
487 that all internal variable references have been interpolated.
488 rel_foo is the same as $exp_foo, only relative to $prefix if they
489 share a common path. [Aaron Bannert]
491 *) Fix some restart/terminate problems in the worker MPM. Don't
492 drop connections during graceful restart. [Jeff Trawick]
494 *) Change the header merging behaviour in proxy, as some headers
495 (like Set-Cookie) cannot be unmerged due to stray commas in
496 dates. [Graham Leggett]
498 *) Be more vocal about what AcceptMutex values we allow, to make
499 us closer to how 1.3 does it. [Jim Jagielski]
501 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
504 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
506 *) Add accessor function to set r->content_type. From now on,
507 ap_rset_content_type() should be used to set r->content_type.
508 This change is required to properly implement the
509 AddOutputFilterByType configuration directive.
510 [Bill Stoddard, Sander Striker, Ryan Bloom]
512 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
513 RFC 3253. Improved the method name/number mapping functions.
516 *) remove sock_enable_linger from connection.c [Ian Holsman]
518 *) Fix for virtual host processing where the requested hostname
519 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
521 *) mod_dav's APIs for REPORT response handling was changed so that
522 providers can generate the content directly into the output filter
523 stack, rather than buffering the response into memory. [Greg Stein]
525 *) Fix a hang condition with graceful restart and prefork MPM
526 in the situation where MaxClients is very high but
527 much fewer servers are actually started at the time of the
528 restart. [Jeff Trawick]
530 *) Small performance fixes for mod_include [Brian Pane]
532 *) Performance improvement for the error logger [Brian Pane]
534 *) Change configure so that Solaris 8 and above have
535 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
536 according to sun people solaris 8+ doesn't have a thundering
537 herd problem [Ian Holsman]
539 *) Allow URIs specifying CGI scripts to include '/' at the end
540 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
541 which ignore '/' at the end of the names of non-directories).
542 PR 10138 [Jeff Trawick]
544 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
545 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
547 *) Fix apxs -g handling. Move config_vars.mk from the top build
548 directory to the build directory. PR 10163 [Jeff Trawick]
550 *) Fix some mod_include problems which broke evaluation of some
551 expressions. PR 10108 [Jeff Trawick]
553 *) Fix the calculation of request time in mod_status. [Stas Bekman]
555 *) Fix the calculation of thread_num in the worker score structure.
558 *) Use apr_atomic operations in managing the mod_mem_cache
559 cache_objects for SMP scalability. (see USE_ATOMICS
560 preprocessor directive in mod_file_cache)
563 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
564 preprocessor directive in mod_file_cache)
567 *) Implement prototype mod_disk_cache for use with mod_cache.
570 *) Add a missing manualdir entry in the Debian config.layout.
571 [Thom May <thom@planetarytramp.net>]
573 *) Stop installing libtool for APR and tell APR where it should place
574 its copy of libtool (via our installbuildpath layout variable).
577 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
578 when reading from a remote HTTP server in proxy. [Graham Leggett]
580 *) Modify receive/send loop in proxy_http and proxy_ftp so that
581 should it be necessary, the remote server socket is closed before
582 transmitting the last buffer (set by ProxyIOBufferSize) to the
583 client. This prevents the backend server from being forced to hang
584 around while the last few bytes are transmitted to a slow client.
585 Fix the case where no error checking was performed on the final
586 brigade in the loop. [Graham Leggett]
588 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
589 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
590 hours. [Graham Leggett, Bill Stoddard]
592 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
593 for a undefined variable. [Ian Holsman]
595 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
596 when we can't get a socket in the specified address family. We may
597 have gotten back an IPv6 address first and yet our system is not
598 configured to allow IPv6 sockets. [Jeff Trawick]
600 *) Be more careful about recursively removing CVS directories. Make
601 sure that we aren't cd'ing to their home directory first. PR: 9993
602 [Aaron Bannert, James LewisMoss <dres@lewismoss.net>]
604 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
605 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
606 Thom May <thom@planetarytramp.net>]
608 *) Rename the filter ordering priorities. The recent filtering fixes
609 have showcased problems with their usage. Therefore, we need to
610 rename them to increase the clarity. (CONTENT->RESOURCE,
611 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
613 Changes with Apache 2.0.33
615 *) Fix a problem in the new --enable-layout functionality where
616 it wouldn't allow overrides from variables like --prefix,
617 --bindir, etc. [Thom May <thom@planetarytramp.net>]
619 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
620 no longer hangs around waiting for the socket to close before
621 returning exhaustive data. [Aaron Bannert]
623 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
624 [Thom May <thom@planetarytramp.net>]
626 *) Change mod_ssl to always do a full startup/teardown on restarts.
627 this allows mod_ssl to be added to a server that is already
628 running and makes it possible to add/change certs/keys after the
629 server has been started. [Doug MacEachern]
631 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
632 This pipe must be a bidirectional 'console' style relay, which
633 mod_ssl prints all prompts to the pipe's stdin, and reads the
634 passphrases from the pipe's stdout. [William Rowe]
636 *) Fix bug where --sysconfdir and --localstatedir were being
637 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
640 *) Fix --enable-layout to work again. Caution: When specifying
641 --enable-layout, common arguments like --prefix, --exec-prefix,
642 etc. will be ignored and the settings from the layout will be
643 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
646 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
647 regex pattern matching for the determination of which requests
648 to use the remote proxy for. [Jim Jagielski]
650 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
652 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
653 cruft in piped logs and rewritemap child processes.
656 *) All instances of apr_lock_t have been removed and converted
657 to one of the following new lock APIs: apr_thread_mutex.h,
658 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
659 use the apr_lock.h API, as the old API will soon be deprecated.
662 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
663 [Ralf S. Engelschall, Cliff Woolley]
665 *) mod-include: make it handle flush'es and fix the 'false-alarm'
666 [Justin Erenkrantz, Brian Pane, Ian Holsman]
668 *) ap_get_*_filter_handle() functions to allow 3rd party modules
669 to lookup filter handles so they can bypass the filter name
670 lookup when adding filters to a request (via ap_add_*_filter_handle())
671 [Ryan Morgan <rmorgan@covalent.net>]
673 *) Fix for multiple file buckets on Win32, where the first file
674 bucket would cause the immediate closure of the socket on any
675 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
677 *) Correct Win32 failure of mmap of a segment beyond start of the
678 file; fixes large SSL and similar transfers. [William Rowe]
681 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
682 multi-process mode to not "daemonize" while detaching from the
683 controlling terminal. This is necessary for Apache to work with
684 process-management tools like AIX's "System Resource Controller"
685 as well as Dan Bernstein's "daemontools".
686 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
688 *) Convert mod_auth_digest to use the new apr_global_mutex_t
689 type. [Aaron Bannert]
691 *) fix bug in mod-include where it wouldn't send a unmatched
692 part if it was at the end of a bucket [Ian Holsman]
694 *) worker MPM: Improve logging of errors with the interface between
695 the listener thread and worker threads. [Jeff Trawick]
697 *) Some browsers ignore cookies that have been merged into a
698 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
699 are now unmerged in the http proxy before being sent to the
700 client. [Graham Leggett]
702 *) Fix a problem with proxy where each entry of a duplicated
703 header such as Set-Cookie would overwrite and obliterate the
704 previous value of the header, resulting in multiple header
705 values (like cookies) going missing.
706 [Graham Leggett, Joshua Slive]
708 *) Add the server-limit and thread-limit values to the scoreboard
709 for the sake of third-party applications.
710 [Adam Sussman <myddryn@vishnu.vidya.com>]
712 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
714 *) OS/390: Get make install to properly copy DSO modules.
717 *) Win32: Fix bug in mod_status with displaying "Restart Time"
721 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
723 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
725 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
726 [David MacKenzie <djm@pix.net>]
728 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
729 [David MacKenzie <djm@pix.net>]
731 *) Fix segfault and display error when SSLMutex file can not be
732 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
734 *) Add reference counting to mod_mem_cache cache objects to
735 better manage removing objects from the cache.
738 *) Change the verbage on the ScoreBoardFile in our default configs.
739 Also change the default to be commented out (unspecified) so we
740 get anonymous shared memory by default. [Aaron Bannert]
742 *) Implement new ScoreBoardFile directive logic. This affects how
743 we create the scoreboard's shared memory segment. If the directive
744 is present, a name-based segment is created. If the directive is
745 not present, first an anonymous segment is created, and if that
746 fails, a name-based segment is created from a file of the name
747 DEFAULT_SCOREBOARD. This gives third-party applications the
748 ability to access our scoreboard. [Aaron Bannert]
750 *) Allow mod_deflate to work with non-GET requests and properly send
751 Content-Lengths. [Sander Striker <striker@apache.org>]
753 *) Fix ap_directory_merge() to correctly merge configs when there is
754 no <Directory /> block. [Justin Erenkrantz, William Rowe]
756 *) Remove spurious debug messsages that are normal under HTTP
757 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
759 *) Fix a bug in mod_cgid that would prevent proper shutdown death
760 of the cgid process. [Aaron Bannert]
762 *) Add signal handling back in to the worker MPM for the one_process
763 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
765 *) Performance: Reuse per-connection transaction pools in the
766 worker MPM, rather than destroying and recreating them. [Brian Pane]
768 *) Remove all signals from the worker MPM's child process. Instead,
769 the parent uses the Pipe of Death for all communication with the
770 child processes. [Ryan Bloom]
772 Changes with Apache 2.0.32
774 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
775 default if the directive is not specified. This mirrors older
776 behavior without changes to the httpd.conf. [William Rowe]
778 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
779 the service, mpm and logging code, and bugs in apr_file_open_stderr
780 and apr_file_dup2 functions. Win2K/XP services have no handles
781 associated for stdin/out/err, which caused unpredictable behavior
782 in the prior release. [William Rowe, Bill Stoddard]
784 *) Win32: simplify the Application Event Log messages, since there isn't
785 likely to be 'more information in the error log' before an error log
786 has been opened. [William Rowe]
788 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
789 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
791 *) Win32: apache -k shutdown now behaves like apache -k stop.
794 *) Fix prefork to not kill the parent if a child hits a resource shortage
795 on accept(). [Greg Ames]
797 *) Fix seg faults that occur when what should be the httpd request line
798 starts with \r\n followed by garbage. [Greg Ames]
800 *) Allow statically linked support binaries with the new
801 --enable-static-support flag, and enable this behavior in
802 the binbuild script. Also add a new --enable-static-htdbm
803 flag. [Aaron Bannert]
805 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
806 do only one stat() call when generating the directory listings.
809 *) Fix resolve_symlink to save the original symlink name if known.
812 *) Be a bit more sane with regard to CanonicalNames. If the user has
813 specified they want to use the CanonicalName, but they have not
814 configured a port with the ServerName, then use the same port that
815 the original request used. [Ryan Bloom and Ken Coar]
817 *) In core_input_filter, check for an empty brigade after
818 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
819 client says it will post some data but we get FIN before any
820 data arrives. [Jeff Trawick]
822 *) Not being able to bind to the socket is a fatal error. We should
823 print an error to the console, and return a non-zero status code.
824 With these changes, all of the Unix MPMs do that correctly.
827 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
828 through to CGI scripts. PR 9163
829 [Brian Reid <breid@customlogic.com>,
830 Zvi Har'El <rl@math.technion.ac.il>]
832 *) binbuild.sh: Make sure that we use the expat from our source
833 tree so that there aren't any surprises on the target machine.
836 *) mod_cgid: Add retry logic for when the daemon can't fork fast
837 enough to keep up with new requests. Start using
838 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
839 when we can't talk to the daemon. [Jeff Trawick]
841 *) apxs: LTFLAGS envvar can override default libtool options. Try
842 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
843 the covers. [Jeff Trawick]
845 *) The Location: response header field, used for external
846 redirect, *must* be an absoluteURI. The Redirect directive
847 tested for that, but RedirectMatch didn't -- it would allow
848 almost anything through. Now it will try to turn an abs_path
849 into an absoluteURI, but it will correctly varf like Redirect
850 if the final redirection target isn't an absoluteURI. [Ken Coar]
852 Changes with Apache 2.0.31
854 *) Create the scoreboard (in the parent) in a global pool context,
855 so it survives graceful restarts. This fixes a SEGV during
856 graceful restarts. [Aaron Bannert]
858 *) Add a timeout option to the proxy code 'ProxyTimeout'
861 *) FTP directory listings are now always retrieved in ASCII mode.
862 The FTP proxy properly escapes URI's and HTML in the generated
863 listing, and escapes the path components when talking to the FTP
864 server. It is now possible to browse the root directory by using
865 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
866 Also, the last path component may contain wildcard characters
867 '*' and '?', and if they do, a directory listing is created instead
868 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
871 *) Added single-listener unserialized accept support to the
872 worker MPM [Brian Pane]
874 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
875 the incoming host header through to the proxied server
876 [Geoff <g.russell@ieee.org>]
878 *) New Directive Option for ProxyPass. It now can block a location
879 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
881 *) Don't let the default handler try to serve a raw directory. At
882 best you get gibberish. Much worse things can happen depending
883 on the OS. [Jeff Trawick]
885 *) Change the pre_config hook to return a value. Modules can now emit
886 an error message and then cause the server to quit gracefully during
887 startup. This required a bump to the MMN. [Aaron Bannert]
889 *) Fix some unix socket descriptor leaks in the handler side of
890 mod_cgid (the part that runs in the server process). Whack a
891 silly "close(-1)" in the handler too. [Jeff Trawick]
893 *) Change the pre_mpm hook to return a value, so that scoreboard
894 init errors percolate up to code that knows how to exit
895 cleanly. This required a bump to the MMN. [Jeff Trawick]
897 *) Add the socket back to the conn_rec and remove the create_connection
898 hook. The create_connection hook had a design flaw that did not
899 allow creating connections based on vhost info. [Bill Stoddard]
901 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
902 Resolves the common case of using negotation to resolve the request
903 /script/foo for /script.cgi/foo. [William Rowe]
905 *) Added new functions ap_add_(input|output)_filter_handle to
906 allow modules to bypass the usual filter name lookup when
907 adding hard-coded filters to a request [Brian Pane]
909 *) caching should now work on subrequests (still very experimental)
912 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
914 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
917 *) Refactor ap_rgetline so that it does not use an internal brigade.
918 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
920 *) Remove mod_auth_db. [Justin Erenkrantz]
922 *) Do not install unnecessary pcre headers like config.h and internal.h.
923 [Joe Orton <joe@manyfish.co.uk>]
925 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
926 (as it does for a normal request). quick_handled sub-requests now work
927 in mod-include [Ian Holsman]
929 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
930 'CONTENT' one, as it needs to run AFTER all content headers
932 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
935 *) Split out blocking from the mode in the input filters.
938 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
940 *) Cause Win32 to capture all child-worker process errors in
941 Apache to the main server error log, until the child can
942 open its own error logs. [William Rowe]
944 *) HPUX 11.*: Do not kill the child process when accept()
945 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
946 by [madhusudan_mathihalli@hp.com])
949 *) Fix a problem in the parsing of the <Proxy foo> directive.
952 *) rewrite of mod_ssl input filter for better performance and less
953 memory usage [Doug MacEachern]
955 *) allow quick_handler to be run on subrequests. [Ian Holsman]
957 *) mod_dav now asks its provider to place content directly into the
958 filter stack when handling a GET request. The mod_dav/provider
959 API has changed, so providers need to be updated. [Greg Stein]
961 *) Clear the output socket descriptor in unixd_accept() to make sure
962 we don't supply a bogus socket to the caller if the accept fails.
963 This caused problems with the worker MPM, which tried to process
964 the returned socket if it was non-NULL. [Brian Pane]
966 *) Move a check for an empty brigade to the start of core input filter
967 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
969 *) Add FileETag directive to allow configurable control of what
970 data are used to form ETag values for file-based URIs. MMN
971 bumped to 20020111 because of fields added to the end of
972 the core_dir_config structure. [Ken Coar]
974 *) Fix a segfault in mod_rewrite's logging code caused by passing the
975 wrong config to ap_get_remote_host(). [Jeff Trawick]
977 *) Allow mod_cgid to work from a binary distribution install by
978 using 755 for the permissions on the log directory instead of
981 *) Fixed a segfault that happened during graceful shutdown (or when
982 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
984 *) Split all Win32 modules [excluding the core components mod_core,
985 mod_so, mod_win32 and the winnt mpm] into individual loadable
986 modules, so the administrator may individually disable the former
987 compiled-in modules by simply commenting out their LoadModule
988 directives. [William Rowe]
990 *) Saved Win32 module authors and porters many future headaches, by
991 duplicating the appropriate .h files such as os.h into the include
992 directory, including in the build tree. [William Rowe]
994 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
995 Use SSL functions/macros instead of directly dereferencing SSL
996 structures wherever possible.
997 Add type-casts for the cases where functions return a generic pointer.
998 Add $SSL/include to configure search path.
999 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1001 *) Moved several pointers out of the shared Scoreboard so it is
1002 more portable, and will present the vhost name across server
1003 generation restarts. [William Rowe]
1005 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
1008 Changes with Apache 2.0.30
1010 *) Fix the main bug for FreeBSD and threaded MPM's. There are
1011 still issues (see STATUS) but at least the server will now
1012 run without crashing the machine.
1013 [David Reid, Aaron Bannert, Justin Erenkrantz]
1015 *) Fix a typo in mod_deflate's m4 config section.
1016 [albert chin (china@thewrittenword.com)]
1018 *) Fix a couple of mod_proxy problems forwarding HTTP connections
1019 and handling CONNECT:
1020 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
1021 (2) Proxy failed to connect when the first IP address returned by
1022 the resolver was unreachable but a secondary IP address was.
1025 *) Fix the module identifer as shown in the docs for various core
1026 modules (e.g., the identifer for mod_log_config was previously
1027 listed as config_log_module). PR #9338
1028 [James Watson <ap2bug@sowega.org>]
1030 *) Fix LimitRequestBody directive by placing it in the HTTP
1031 filter. [Justin Erenkrantz]
1033 *) Fix mod_proxy seg fault when the proxied server returns
1034 an HTTP/0.9 response or a bogus status line.
1037 *) Prevent mod_proxy from truncating one character off the
1038 end of the status line returned from the proxied server.
1039 [Adam Sussman, Bill Stoddard]
1041 *) Eliminate loop in ap_proxy_string_read().
1042 [Adam Sussman, Bill Stoddard]
1044 *) Provide $0..$9 results from mod_include regex parsing.
1047 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
1049 *) Introduced the ForceLanguagePriority directive, to prevent
1050 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
1051 when using Multiviews. [William Rowe]
1053 *) Fix a problem which prevented mod_cgid and suexec from working
1054 together reliably [Greg Ames]
1056 *) Remove the call to exit() from within mod_auth_digest's post_config
1057 phase. [Aaron Bannert]
1059 *) Fix a problem in mod_auth_digest that could potentially cause
1060 problems with initialized static data on a system that uses DSOs.
1063 *) Fix a segfault in the worker MPM that could happen during
1064 child process exits. [Brian Pane, Aaron Bannert]
1066 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
1068 *) Fix matching of vhosts by ip address so we find IPv4
1069 vhost address when target address is v4-mapped form of
1070 that address. [Jeff Trawick]
1072 *) More performance tweaks to the BNDM string-search algorithm
1073 used to find "<!--#" tokens in mod_include [Brian Pane]
1075 *) Miscellaneous small performance fixes: optimized away various
1076 string copy operations and removed large temp buffers from
1077 the stack [Brian Pane]
1079 *) Fixed startup segfault that occurred when a VirtualHost
1080 directive had a port but no address [Brian Pane]
1082 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
1084 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
1085 if oslevel < WINNT. This should fix several problems reported
1086 Against 2.0.28 on Windows 98 [Bill Stoddard]
1088 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
1089 to fail. [Bill Stoddard]
1091 *) Change core code to allow an MPM to set hard thread/server
1092 limits at startup. prefork, worker, and perchild MPMs now have
1093 directives to set these limits. [Jeff Trawick]
1095 *) Win32: The async AcceptEx() event should be autoreset upon
1096 successful completion of a wait (WaitForSingleObject). This
1097 eliminates a number of spurious
1098 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
1101 *) Move any load library path environment variables out of
1102 apachectl and into a separate environment variable file which
1103 can be more easily tailored by the admin. The environment
1104 variable file as built by Apache may have additional system-
1105 specific settings. For example, on OS/390 we tailor the heap
1106 settings to allow lots of threads. [Jeff Trawick]
1108 *) Use the new APR pool code to reduce pool-related lock
1109 contention in the worker MPM. [Sander Striker]
1111 *) The POD no longer assumes the child is listening on 127.0.0.1
1112 and now pulls the first hostname in the list of listeners to
1113 perform the dummy connect on. This fixes a bug when the user
1114 had configured the Listen directive for an IP other than
1115 127.0.0.1. This would result in undead children and error
1116 messages such as "Connection refused: connect to listener".
1119 *) The worker MPM now respects the LockFile setting, needed to
1120 avoid locking problems with NFS. [Jeff Trawick]
1122 *) Fix segfault when worker MPM receives SIGHUP.
1123 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
1125 *) Fix bug that could potentially prevent the perchild MPM from
1126 working with more than one vhost/uid. [Aaron Bannert]
1128 *) Change make install and apxs -i processing of DSO modules to
1129 perform special handling on platforms where libtool doesn't install
1130 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
1131 which prevented standard LoadModule statements from working.
1134 *) Whenever mod_so is enabled (not just when there are DSOs for
1135 our modules), do whatever special magic is required for compiling/
1136 loading third-party modules. This allows third-party DSOs to
1137 be used on an AIX build when there were no built-in modules
1138 built as DSOs. (This should help on OS/390 and BeOS as well.)
1141 *) Allow apxs to be used to build DSOs on AIX without requiring the
1142 user to hard-code the list of import files. (This should help
1143 on OS/390 and BeOS as well.) [Jeff Trawick]
1145 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
1146 PR 8563, 8919 [William Rowe]
1148 *) Get binary builds working when libapr and libaprutil are built
1151 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
1152 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
1153 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
1155 *) Fix the handling of SSI directives in which the ">" of the
1156 terminating "-->" is the last byte in a file [Brian Pane]
1158 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
1159 message that we had back in apache-1.3 and still have scattered
1160 throughout our docs. [Aaron Bannert]
1162 *) Prevent the Win32 port from continuing after encountering an
1163 error in the command line args to apache. [William Rowe]
1165 *) On a error in the proxy, make it write a line to the error log
1168 *) Various mod_ssl performance improvements [Doug MacEachern]
1170 Changes with Apache 2.0.29
1172 *) Add buffering in core_output_filter to ensure that long
1173 lists of small buckets don't cause small packet writes.
1174 [Brian Pane, Ryan Bloom]
1176 *) Fix the installation target to make sure that the manual is
1177 installed in the correct location.
1178 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
1179 Gomez Henri <hgomez@slib.fr>]
1181 *) Fix the cmd command for mod_include. When we are processing
1182 a cmd command, we do not want to use the r->filename to set
1183 the command name. The command comes from the SSI tag. To do this,
1184 I added a variable to the function that builds the command line
1185 in mod_cgi. This allows the include_cmd function to specify
1186 the command line itself. [Ryan Bloom]
1188 *) Change open_logs hook to return a value, allowing you
1189 to flag a error while opening logs
1190 [Ian Holsman, Doug MacEachern]
1192 *) Change post_config hook to return a value, allowing you
1193 to flag a error post config
1194 [Ian Holsman, Jeff Trawick]
1196 *) Allow SUEXEC_BIN (the path to the suexec binary that is
1197 hard-coded into the server) to be specified to the configure
1198 script by the --with-suexec-bin parameter. [Aaron Bannert]
1200 *) Fix segv in worker MPM following accept on pipe-of-death
1203 *) Add mod_deflate to experimental.
1204 [Ian Holsman, Justin Erenkrantz]
1206 *) Bail out at configure time if an invalid MPM was specified.
1207 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1209 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
1210 configured [John Sterling <sterling@covalent.net>]
1212 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
1214 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
1216 *) Optimization for the BNDM string-search function in
1217 mod_include. [Brian Pane]
1219 *) Fixed the behavior of the XBitHack directive.
1220 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
1222 *) The threaded MPM for Unix has been removed. Use the worker
1223 MPM instead. [various]
1225 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
1226 in logging the error from a failed DNS lookup. [Jeff Trawick]
1228 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
1231 *) Get mod_cgid killed when a MPM exits due to a fatal error.
1234 *) Fix a file descriptor leak in mod_include. When we include a
1235 file, we use a sub-request, but we didn't destroy the sub-request
1236 immediately, instead we waited until the original request was
1237 done. This patch closes the sub-request as soon as the data is
1238 done being generated. [Brian Pane <bpane@pacbell.net>]
1240 *) Allow modules that add sockets to the ap_listeners list to
1241 define the function that should be used to accept on that
1242 socket. Each MPM can define their own function to use for
1243 the accept function with the MPM_ACCEPT_FUNC macro. This
1244 also abstracts out all of the Unix accept error handling
1245 logic, which has become out of synch across Unix MPMs.
1248 *) Fix a bug which would cause the response headers to be omitted
1249 when sending a negotiated ErrorDocument because the required
1250 filters were attached to the wrong request_rec.
1251 [John Sterling <sterling@covalent.net>]
1253 *) Remove commas from the end of the macros that define
1254 directives that are used by MPMs. Prior to this patch,
1255 you would use these macros without commas, which was unlike
1256 the macros for any other directives. Now, the caller provides
1257 the comma rather than the macro providing it. This makes
1258 the macros look more like the rest of the directives.
1259 [Ryan Bloom and Cliff Woolley]
1261 *) Add 'redirect-carefully' environment option to disable sending
1262 redirects under special circumstances. This is helpful for
1263 Microsoft's WebFolders when accessing a directory resource via
1264 DAV methods. [Justin Erenkrantz]
1266 *) Begin to abstract out the underlying transport layer.
1267 The first step is to remove the socket from the conn_rec,
1268 the server now lives in a context that is passed to the
1269 core's input and output filters. This forces us to be very
1270 careful when adding calls that use the socket directly,
1271 because the socket isn't available in most locations.
1274 *) Really reset the MaxClients value in worker and threaded
1275 when the configured value is not a multiple of the number
1276 of threads per child. We said we did previously but we
1277 forgot to. [Jeff Trawick]
1279 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
1281 *) If shared modules are requested and mod_so is not available,
1282 produce a fatal config-time error. [Justin Erenkrantz]
1284 *) Improve http2env's performance by cutting the work it has to
1285 do. [Brian Pane <bpane@pacbell.net>]
1287 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
1288 [Brian Pane <bpane@pacbell.net>]
1290 Changes with Apache 2.0.28
1292 *) Fix infinite loop in mod_cgid.c.
1293 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
1295 *) When no port is given in a "ServerName host" directive, the
1296 server_rec->port is now set to zero, not 80. That allows for
1297 run-time deduction of the correct server port (depending on
1298 SSL/plain, and depending also on the current setting of
1299 UseCanonicalName). This change makes redirections
1300 work, even with https:// connections. As in Apache-1.3, the
1301 connection's actual port number is never used, only the ServerName
1302 setting or the client's Host: setting. Documentation updated
1303 to reflect the change. [Martin Kraemer]
1305 *) Add a '%{note-name}e' argument to mod-headers, which works in
1306 the same way as mod_log_confg. [Ian Holsman]
1308 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
1309 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
1310 MPMs. [Cliff Woolley]
1312 *) Introduce htdbm, a user management utility for db/dbm authorization
1313 databases. [Mladen Turk <mturk@mappingsoft.com>]
1315 *) Optimize usage of strlen and strcat in ap_directory_walk.
1316 [Brian Pane <bpane@pacbell.net>]
1318 Changes with Apache 2.0.27
1320 *) Introduce an Apache mod_ssl initial configuration template
1321 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
1323 *) Fixed a memory leak in the getline parsing code that could
1324 be triggered by arbitrarily large header lines. Requests
1325 from the core input filter for single lines are now limited
1326 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
1328 *) Fix a truncation bug in how we print the port on the Via: header.
1329 The routine that prints the Via: header now takes a length for
1330 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
1332 *) Some syntax errors in mod_mime_magic's magic file can result
1333 in a 500 error, which previously was unlogged. Now we log the
1334 error. [Jeff Trawick]
1336 *) Add the support/checkgid helper app, which checks the run-time
1337 validity of group identifiers usable in the Group directive.
1340 *) Various --enable-so options have been fixed: --enable-so is
1341 treated as "static"; explicit --enable-so=shared issues an error;
1342 and explicit --enable-so fails with error on systems without
1343 APR_HAS_DSO. [Aaron Bannert]
1345 *) Fix a segfault in the core input filter when the client socket
1346 gets disconnected unexpectedly. [Cliff Woolley]
1348 *) Fix the reporting for child processes that die. This removes
1349 all of the non-portable W* macros from Apache.
1350 [Jeff Trawick and Ryan Bloom]
1352 *) Win32: Track and display "Parent Server Generation:" in
1353 mod_status output. The generation will be bumped at
1354 server graceful restart, when the child process exits
1355 by hitting MaxRequestsPerChild or if the child
1356 process exits abnormally. [Bill Stoddard]
1358 *) Win32: Fix problem where MaxRequestsPerChild directive was
1359 not being picked up in favor of the default. Enable
1360 the parent to start up a new child process immediately upon
1361 the old child starting shutdown.
1364 *) Fix some bungling of the remote port in rfc1413.c so that
1365 IdentityCheck retrieves the proper user id instead of failing
1366 and thus always returning "nobody."
1367 [Dick Streefland <Dick.Streefland@xs4all.nl>]
1369 *) Introduced thread saftey for mod_rewrite's internal cache.
1370 [Brian Pane <bpane@pacbell.net>]
1372 *) Simplified mod_env's directives to behave as most directives are
1373 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
1374 directive following that UnsetEnv within the same container.
1375 Also provides a runtime startup warning if a PassEnv configured
1376 environment value is undefined. [William Rowe]
1378 *) The worker MPM is now completely ported to APR's new lock API. It
1379 uses native APR types for thread mutexes, cross-process mutexes,
1380 and condition variables. [Aaron Bannert]
1382 *) Sync up documentation to remove all references to the now deprecated
1383 Port directive. [Justin Erenkrantz]
1385 *) Moved all ldap modules from the core to httpd-ldap sub-project
1388 *) Exit when we can't listen on any of the configured ports. This
1389 is the same behavior as 1.3, and it avoids having the MPMs to
1390 deal with bogus ap_listen_rec structures. [Jeff Trawick]
1392 *) Cleanup the proxy code that creates a request to the origin
1393 server. This change adds an optional hook, which allows modules
1394 to gain control while the request is created if the proxy module
1395 is loaded. The purpose of this hook is to allow modules to add
1396 input and/or output filters to the request to the origin. While
1397 I was at it, I made the core use this hook, so that proxy request
1398 creation uses some of the code from the core. This can still be
1399 greatly improved, but this is a good start. [Ryan Bloom]
1401 Changes with Apache 2.0.26
1403 *) Port the MaxClients changes from the worker MPM to the threaded
1406 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
1407 with the new input filtering system. [Justin Erenkrantz]
1409 *) Introduce the MultiviewsMatch directive, to allow the operator
1410 to be flexible in recognizing Handlers and Filters filename
1411 extensions as part of the Multiviews matching logic, strict with
1412 MultiviewsMatch NegotiatedOnly to accept only filename extentions
1413 that designate negotiated parameters, (content type, charset, etc.)
1414 or MultiviewsAll for the 1.3 behavior of matching any files, even
1415 if they have unregistered extensions. [William Rowe]
1417 *) Fixed the configure script to add a LoadModule directive to
1418 the default httpd.conf for any module that was compiled
1419 as a DSO. [Aaron Bannert <aaron@clove.org>]
1421 *) rewrite mod_ssl input filtering to work with the new input filtering
1422 system. [Justin Erenkrantz]
1424 *) prefork: Don't segfault when we are able to listen on some but
1425 not all of the configured ports. [Jeff Trawick]
1427 *) Build mod_so even if no core modules are built shared.
1428 [Aaron Bannert <aaron@clove.org>]
1430 *) Introduce ap_directory_walk rewrite (with further optimizations
1431 required) to adapt to the ap_process_request_internal() changes.
1432 Optimized so subrequests and redirects now reuse previous section
1433 merges, until we mismatch with the original directory_walk, and
1434 precomputed r->finfo results will cause directory_walk to skip
1435 the most expensive phases of the function. [William Rowe]
1437 *) Allow ApacheMonitor to connect to and control Apache on other
1438 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
1440 *) Remove the Port directive. In it's place, the Listen directive
1441 is now a required directive, which tells Apache what port to
1442 listen on. The ServerName directive has also been extended
1443 to accept an optional port. If the port is specified to the
1444 ServerName, the server will report that port whenever it
1445 reports the port that it is listening on. This change was
1446 made to ease configuration errors that stem from having a Port
1447 directive, and a Listen directive. In that situation, the server
1448 would only listen to the port specified by the Listen command,
1449 which caused a lot of confusion to users. [Ryan Bloom]
1451 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
1452 build, as loadable modules. [William Rowe]
1454 *) Fix --enable-mods-shared processing. If most is specified,
1455 then all modules that can be compiled as shared modules are.
1456 [Aaron Bannert <aaron@clove.org>]
1458 *) Update the mime.types file to map video/vnd.mpegurl to mxu
1459 and add commonly used audio/x-mpegurl for m3u extensions.
1460 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
1462 *) Eliminate the depreciated r->content_language, in favor of the array
1463 r->content_languages introduced many years ago. Module authors must
1464 substantially overhaul their modules, so this needs to be upgraded
1465 if the module still relied on backwards-brokeness. [William Rowe]
1467 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
1470 *) Rewrite the input filtering mechanisms to consolidate and reorganize
1471 code. In short, core_input_filter does something now and
1472 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
1474 *) Update the Win32 build to re-absorb mod_proxy and family.
1477 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
1478 current SDK.) [William Rowe]
1480 *) Some style changes to the code that does ProxyErrorOverride. Fixed
1481 config merge behaviour. [Graham Leggett]
1483 *) Allow support programs to be compiled against a static version
1484 of libapr. This allows the smaller support programs to be
1485 relocated. [Aaron Bannert <aaron@clove.org>]
1487 *) Update the mime.types file to the registered media types as
1488 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
1490 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
1491 number of clients that can connect at the same time, instead of
1492 specifying the maximum number of child processes.
1493 [Aaron Bannert <aaron@clove.org>]
1495 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
1496 be consistent with 1.3. [Justin Erenkrantz]
1498 *) Cache apr_explode_localtime() value for 15 seconds.
1499 [Brian Pane <bpane@pacbell.net>]
1501 *) Fix mod_include to not return ETag or Last-Modified headers.
1502 [Ian Holsman <ianh@cnet.com>]
1504 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
1506 *) Eliminate the wasteful run-time conversion of method names from strings
1507 to numbers in places where the methods are known at compile time.
1508 [Brian Pane <bpane@pacbell.net>]
1510 *) Turn the worker MPM's queue into a LIFO. This may
1511 improve cache-hit performance under some conditions.
1512 [Aaron Bannert <aaron@clove.org>]
1514 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
1515 support it. [Justin Erenkrantz]
1517 *) Cleanup the worker MPM. We no longer re-use transaction
1518 pools. This incurs less overhead than shuffling the pools
1519 around so that they can be re-used. Remove one of the
1520 queue's condition variables. We just redefined the API to
1521 state that you can't try to add more stuff than you allocated
1522 segments for. [Aaron Bannert <aaron@clove.org>]
1524 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
1526 *) Fixed persistent connections when a request contains a body.
1529 *) mod_dav uses a new API to speak to the backend provider for dead
1530 property management. [Greg Stein]
1532 *) Remove the Win32 script-processing exception from mod_cgi, and
1533 roll build_command_line/build_argv_list into a unified, overrideable
1534 ap_cgi_build_command optional function. [William Rowe]
1536 *) Rewrite find_start_sequence to use a better search algorithm
1537 to find the start tag. [Justin Erenkrantz]
1539 *) Fix a seg fault in mod_include. When we are generating an
1540 internal redirect, we must set r->uri to "", not a bogus
1541 string, and not NULL. [Ryan Bloom]
1543 *) Optimized location_walk, so subrequests, redirects and second passes
1544 now reuse previous section merges on a <Location > by <Location >
1545 basis, until we mismatch with the original location_walk.
1548 *) Back out the 1.45 change to util_script.c. This change made
1549 us set the environment variable REQUEST_URI to the redirected
1550 URI, instead of the originally requested URI.
1551 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1553 *) Make mod_include do lazy evaluation of potentially expensive to
1554 compute variables. [Brian Pane <bpane@pacbell.net>]
1556 *) Fix logging of bytes sent for HEAD requests. %b and %B should
1557 log either - or 0, before this patch, they were both logging
1558 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1560 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
1561 than per character. [Brian Pane <bpane@pacbell.net>]
1563 *) Normalize the primary request, redirects and sub-requests to
1564 run the same ap_process_request_internal for consistency in
1565 robustness, behavior and security. [William Rowe]
1567 *) Fix a segfault with mod_include when r->path_info is not set
1568 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
1570 *) Add -X functionality back. This indicates to all MPMs and any other
1571 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
1573 *) Some initial support for the cygwin platform [prefork only].
1574 This is not to be confused with support for the WinNT/Win32
1575 platform, which is the recommended configuration for native
1576 Win32 users. The cygwin platform support is recommended for
1577 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
1579 *) Changed syntax of Set{Input|Output}Filter. The list of filters
1580 must be semicolon delimited (if more than one filter is given.)
1581 The Set{Input|Output}Filter directive now overrides a parent
1582 container's directive (e.g. SetInputFilter in <Directory /web/foo>
1583 will override any SetInputFilter directive in <Directory /web>.)
1584 This new syntax is more consistent with Add{Input|Output}Filter
1585 directives defined in mod_mime. Also cures a bug in prior releases
1586 where the Set{Input|Output}Filter directive would corrupt the
1587 global configuration if the multiple directives were nested.
1590 *) Cured what's ailed mime for quite some time. If an AddSomething
1591 was given in the configuration (Language, Charset, Handler or
1592 Encoding) Apache would set the content type as given by AddType,
1593 but refused to check the mime.types file if AddType wasn't given
1594 for that specific extension. Setting the AddHandler for .html
1595 without setting the AddType text/html html would cause Apache to
1596 use the default content type. [William Rowe]
1598 *) Added some bulletproofing to memory allocation in the LDAP cache
1599 code. [Graham Leggett]
1601 Changes with Apache 2.0.25
1603 *) Move the installed /manual directory out of the /htdocs/ tree, so
1604 that it can be kept more independently from the remaining document
1605 root. The "Alias /manual ..." already allowed for easy projection
1606 into existing private document trees. [Martin Kraemer]
1608 *) Add specified user attributes to the environment when using
1609 mod_auth_ldap. This allows you to use mod_include to embed specified
1610 user attributes in a page like so:
1611 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
1614 *) Fix a performance problem with the worker MPM. We now create
1615 transaction pools once, and re-use them for each connection.
1616 [Aaron Bannert <aaron@clove.org>]
1618 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
1619 of a 'handler' or 'filter', so that any filename extension that does
1620 not contribute to the negotiated metadata can't be served without
1621 an explicit request. E.g., if the .Z extension is associated with
1622 an unzip filter, the user request somefile.Z.html, mod_negotiation
1623 won't serve it. It can serve somefile.Z.html when somefile.Z is
1624 requested, since the .Z extension is explictly requested, if the
1625 .html extension is associated with ContentType text/html.
1628 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
1629 and corresponding AddOutputFilter syntax, to insert one or more
1630 filters by mod_mime filename extension processing.
1633 *) Fix a growing connection pool in core_output_filter() for
1634 keepalive requests. [Jeff Trawick]
1636 *) Moved split_and_pass_pretag_buckets back to being a
1637 macro at Ryans's request. Removed the return from it
1638 by setting and returning a return code instead. Updated
1639 the code to check the return code from the macro and
1640 do the right thing. [Paul J. Reder]
1642 *) Fix a segfault when a numeric value was received for Host:.
1645 *) Add a function ap_remove_input_filter. This is to match
1646 up with ap_remove_output_filter. [Ryan Bloom]
1648 *) Clean up location_walk, so that this step performs a minimum
1649 amount of redundant effort (it must be run twice, but it will no
1650 longer reparse all <Location > blocks when the request uri
1651 hadn't changed.) [William Rowe]
1653 *) Eliminate proxy: (and all other 'special') processing from the
1654 ap_directory_walk() phase. Modules that want to use special
1655 walk logic should refer to the mod_proxy map_to_location example,
1656 with it's proxy_walk and proxysection implementation. This makes
1657 either directory_walk flavor much more legible, since that phase
1658 only runs against real <Directory > blocks.
1661 *) Fix a security problem in mod_include which would allow
1662 an SSI document to be passed to the client unparsed.
1663 [Cliff Woolley, Brian Pane]
1665 *) Introduce the map_to_storage hook, which allows modules to bypass
1666 the directory_walk and file_walk for non-file requests. TRACE
1667 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
1668 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
1671 *) Add the ability for mod_include to add the INCLUDES filter
1672 if the file is configured for the server-parsed handler.
1673 This makes the configuration for .shtml files much easier
1674 to understand, and allows mod_include to honor Apache 1.3
1675 config files. Based on Doug MacEachern's patch to PHP
1676 to do the same thing. [Ryan Bloom]
1678 *) force OpenSSL to ignore process local-caching and to always
1679 get/set/delete sessions using mod_ssl's callbacks
1680 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1681 Geoff Thorpe <geoff@geoffthorpe.net>]
1683 *) Make the worker MPM shutdown and restart cleanly. This also
1684 cleans up some race conditions, and gets the worker using
1685 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
1687 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
1689 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1691 *) Fix for mod_include. Ryan's patch to check error
1692 codes put a return in the wrong place. Also, the
1693 include handler return code wasn't being checked.
1694 I don't like macros with returns, so I converted
1695 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
1696 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1698 *) fix segv in mod_mime if no AddTypes are configured
1699 [John Sterling <sterling@covalent.net>]
1701 *) Enable ssl client authentication at SSL_accept time
1702 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1704 *) Fix a segfault in mod_include when the original request has no
1705 associated filename (e.g., we're filtering the error document for
1706 a bad URI). [Jeff Trawick]
1708 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
1710 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
1711 of httpd is started and shuts down due to socket conflict. Moving the
1712 call to ap_log_pid solves the problem.
1714 *) Changed the late-1.3 log_config substitution %c to %X, to log the
1715 status of the closed connection, as it conflicts with the far more
1716 common, historical ssl logging directive %...{var}c. [William Rowe]
1718 *) Added the common error/ tree to the build/install targets
1719 (similar to the common icons/ tree) for the multi-language error
1720 messages that Lars committed earlier. [William Rowe]
1722 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
1724 *) Added a default commented-out mod_ldap and mod_auth_ldap
1725 configuration to httpd-std.conf and httpd-win.conf
1728 *) Added documentation for mod_ldap and mod_auth_ldap.
1731 *) Enabled negative caching on attribute comparisons in the LDAP cache.
1732 Fixed a problem where the default cache TTL was set in milliseconds
1733 not microseconds causing the cache to time out almost immediately.
1736 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
1737 module code to follow APR. [Graham Leggett]
1739 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
1740 cleaned up when the connection pool pool is cleaned up.
1743 *) Fix a minor issue with Jeff Trawick's mod_include
1744 patch. Without this patch, the code will just allocate
1745 more bytes in get_combined_directive than are needed.
1748 *) Added the LDAP authentication module mod_auth_ldap.
1749 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1751 *) Added the LDAP cache and connection pooling module mod_ldap.
1752 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1754 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
1755 by allowing a module to disable itself if its prerequisites are not
1756 met. [Justin Erenkrantz]
1758 Changes with Apache 2.0.24
1760 *) Fix a couple of issues in mod_include when the tag appeared at
1761 offsets near 8192 in the file being parsed. [Jeff Trawick]
1763 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
1764 reached. [Jeff Trawick]
1766 *) Numerous improvements to the Win32 build system. Introduced command line
1767 builds without requiring .mak files for MSVC 6.0 and later versions.
1768 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
1771 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
1772 reporting of uninstalled services and other error conditions, and changed the
1773 default service name to Apache2. [William Rowe]
1775 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
1776 compatibility with existing Apache 1.3 Win32 Apache management utilites.
1777 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
1779 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
1780 [William Rowe, Greg Ames]
1782 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
1783 and RemoveCharset directives. [William Rowe]
1785 *) The Unix MPMs other than perchild now allow child server
1786 processes to use the accept mutex when starting as root and
1787 using SysV sems for the accept mutex. Previously, this
1788 combination would lead to fatal errors in the child server
1789 processes. perchild can't use SysV sems because of security
1790 issues. [Jeff Trawick, Greg Ames]
1792 *) Added Win32 revision stamp resources to all http binaries
1793 (including modules/ and support/ tools.) PR7322 [William Rowe]
1795 *) Fix ap_rvprintf to support more than 4K of data at one time.
1796 [Cody Sherr <csherr@covalent.net>]
1798 *) We have always used the obsolete/deprecated Netscape syntax
1799 for our tracking cookies; now the CookieStyle directive
1800 allows the Webmaster to choose the Netscape, RFC2109, or
1801 RFC2965 format. The new CookieDomain directive allows the
1802 setting of the cookie's Domain= attribute, too. PR #s 5006,
1803 5023, 5920, 6140 [Ken Coar]
1805 *) Tweak server/Makefile so that the rules for generating exports.c
1806 are compatible with make utilities which don't expand wildcards
1807 in a dependency list (e.g., OS/390 make, certain levels of GNU
1808 make). [Jeff Trawick]
1810 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
1812 *) Begin to sanitize the MPM configuration directives. Now, all
1813 MPMs use the same functions for all common MPM directives. This
1814 should make it easier to catch all bugs in these directives once.
1815 [Cody Sherr <csherr@covalent.net>]
1817 *) Close a major resource leak. Every time we had issued a
1818 graceful restart, we leaked a socket descriptor.
1821 *) Fix a problem with the new method code. We need to cast
1822 the 1 to an apr_int64_t or it will be treated as a 32-bit
1823 integer, and it will wrap after being shifted 32 times.
1824 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
1826 *) Fix a bug in mod_expires. Previous to this patch, if you
1827 told mod_expires to add 604800 seconds to the last-modified
1828 time, it actually added 604800 usec's to the last-modified time,
1829 so that when looking at the response it looked like nothing
1830 had been done. The root of the problem was that we always compute
1831 time in usec's, but we ask users to input sec's. This means we
1832 need to convert to usec's before using those values.
1835 *) The worker MPM now handles shutdown and restart requests. It
1836 definitely isn't perfect, but we do stop the servers correctly.
1837 The biggest problem right now is that SIGHUP causes the server to
1838 just die. [Ryan Bloom]
1840 Changes with Apache 2.0.23
1842 *) Use the prefork MPM by default on Unix. [various]
1844 *) Added a systray icon monitor application for Win32.
1845 [Mladen Turk <mturk@mappingsoft.com>]
1847 *) mod_rewrite: Fix the line ending on some non-Unix systems for
1848 messages written to the rewrite log.
1849 [Richard Labennett <rlabenn@us.ibm.com>]
1851 *) All mod_autoindex query parsing is now quietly quashed with the
1852 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
1853 still drops the column sort <a href>'s for the column headers, but
1854 IgnoreClient is required to ignore these Query options entirely.
1857 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
1858 to allow the client to select plain, FancyIndexing or HTMLTable
1859 formatting, V=[0|1] to inhibit or enable version sorting, and
1860 P=pattern to return only specific files. The old Query Arguments
1861 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
1862 as before), and O=A|D for ordering ascending or descending.
1865 *) Fixed an error in mod_include's directive parsing routines which
1866 caused #if, #elif, and #else expressions containing backslashes
1867 to be improperly evaluated. [Cliff Woolley]
1869 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
1870 drop the icon column, SuppressRules to drop the <hr> elements,
1871 and HTMLTable to create rudimentary HTML table listings (implies
1872 FancyIndexing). [William Rowe]
1874 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
1875 from Apache 1.3.15. This is needed for two reasons, first, given
1876 multiple machines within a server farm, ETags and Last-Modified
1877 stamps won't correspond from machine to machine, and second, many
1878 Unixes don't capture changes to the date or time stamp of existing
1879 files, since these don't modify the dirent itself. [William Rowe]
1881 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
1882 and DirectoryWidth options from Apache 1.3.10.
1883 [William Rowe, Ken Coar]
1885 *) Eliminated FancyIndexing directive, deprecated early in Apache
1886 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
1888 *) mod_autoindex now excludes any file names that would result in
1889 an error, other than a success or redirect. Also optimized
1890 the parent directory, always included except in the URI '/'.
1893 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
1894 negotiated index pages, and prevent the server from defaulting
1895 to an autoindex of the directory. mod_negotiation will now die
1896 with a 500 Internal Error if it could match some filenames
1897 (e.g. for mod_dir) but none can be served. mod_negotation now
1898 refuses to serve any file with an extention that mod_mime doesn't
1899 recognize, and wasn't part of the request. [William Rowe]
1901 *) Eliminate mod_cgi's handling of .exe files without the .exe file
1902 extension. This is already handled by multiviews, if the admin
1903 wishes to AddHandler .exe or define a content type handler and
1904 associate .exe files with that content type. Multiviews must be
1905 enabled to allow these to be served. [William Rowe]
1907 *) Speed up the server's response to a spike in incoming workload
1908 or restarts by assigning empty scoreboard slots to new processes
1909 when they are available. [Greg Ames]
1911 *) Add a handler to mod_includes.c. This handler is designed to
1912 implement the XbitHack directive. This can't be done with a
1913 fixup, because we need to check the content-type, which is
1914 only available in the handler phase. [Ryan Bloom]
1916 *) Make the includes filter check return codes from filters lower in
1917 the filter chain. If a lower level filter returns an error, then
1918 the request needs to stop immediately. This allows mod_include to
1919 stop parsing data once a lower filter recognizes an error.
1922 *) Add the ability to extend the methods that Apache understands
1923 and have those methods <limit>able in the httpd.conf. It uses
1924 the same bit mask/shifted offset as the original HTTP methods
1925 such as M_GET or M_POST, but expands the total bits from an int to
1926 an ap_int64_t to handle more bits for new request methods than
1927 an int provides. [Cody Sherr <csherr@covalent.net>]
1929 *) Fix broken mod_mime behavior in merging its arguments. Possible
1930 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
1932 *) Solve many mod_ssl porting issues (too many to detail) with
1933 help from the whole team, but most notably [Ralf S. Engelschall,
1934 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1935 Doug MacEachern, William Rowe, Cliff Woolley]
1937 *) More stall fixes for the threaded & worker mpm's.
1938 Make mod_status output more accurate. Don't
1939 count workers in processes which aren't actively
1940 serving requests. [Greg Ames]
1942 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
1944 *) Add a single listener/multiple worker MPM. This MPM is
1945 definately not fully correct, but it allows us to solve many
1946 of the problems that exist in the threaded MPM. This is a
1947 modified version of the threaded MPM. [Ryan Bloom]
1949 *) Improve content generation throughout Apache, providing closer
1950 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
1951 Transitional specifications. [William Rowe]
1953 Changes with Apache 2.0.22
1955 *) Fix a problem where the threaded MPM stalls after restarts or
1956 segfaults. Also prevent multiple active processes from using
1957 the same scoreboard slot. [Greg Ames]
1959 *) Apache/Win32 now fills in the service description with Apache's
1960 server version string, including loaded and advertised modules.
1963 *) Improved support for the Win32 build, to recover gracefully from
1964 missing apr or apr-util directories or the awk interpreter,
1965 create the proper cgi-bin examples, including a test-cgi.bat, and
1966 fix the perl shebang line for printenv.pl, when installing from
1967 the build environment. [William Rowe]
1969 *) Fix a segfault in threaded.c caused by passing uninitialized
1970 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
1972 *) Use new APR number conversion functions to reduce CPU consumption
1973 when setting the content length, and in mod_log_config.
1976 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
1977 where HEAD response headers were being repeated twice for
1978 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
1979 problem in the http_header filter was exposed by the recent rewrite
1980 of the content_length filter. [Taketo Kabe, Bill Stoddard]
1982 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
1983 restarts. A garbage pointer to a vhost's server_rec from the
1984 previous generation was being left around under certain
1985 conditions. [Greg Ames]
1987 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
1988 used to appear as '(none', without the closing paren.
1989 [Günter Knauf <eflash@gmx.net>]
1991 *) Improve the exports generating awk script. In the past, we had
1992 work around problems in the awk script by avoiding some #if and
1993 #ifdefs. This has bitten us many times in generating the exports.c
1994 file. This improvement allows corrects the header file parsing.
1995 [Sander Striker <striker@apache.org>]
1997 Changes with Apache 2.0.21
1999 *) Resolve the Win32 htpasswd bug, where a file that existed would be
2000 overwritten, regardless of the -c flag.
2001 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
2003 *) Introduce connection sub-pools into ab. Truncating the lifetime
2004 of these allocations means that ab no longer perpetually grows
2005 its working set, running out of memory on large request attempts.
2008 *) Make scoreboard creation a hook. This allows management
2009 modules to have access to the scoreboard at the time that it is
2010 created, and at every restart request.
2011 [Cody Sherr <csherr@covalent.net>]
2013 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
2014 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
2015 daemon index actually used in the scoreboard. I also
2016 updated the pertinent calls. [Paul J. Reder]
2018 *) Win32: Prevent listening sockets from being inherited by
2019 the Apache child process, CGI scripts, rotatelog process
2020 etc. If the Apache child process segfaults, any processes
2021 that the child started are not reaped. Prior to this fix,
2022 these processes inherited the listening sockets which sometimes
2023 prevented the restarted Apache child process from accepting
2024 connections (ie, the server would hang).
2027 *) Provide vhost and request strings when ExtendedStatus is on.
2030 *) Fix some issues with the pod and prefork: check the pod *after*
2031 processing a connection so that a server processing a time-
2032 consuming request bails out as soon as practical; when the
2033 parent process wakes up a server process via connect(), use an
2034 APR timeout on the connect() so that we don't hang for a long
2035 time if there aren't server processes around to do accept().
2036 [Jeff Trawick, Greg Ames]
2038 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
2039 spends a lot of time in apr_table_get calls. Using the default
2040 httpd.conf, the tables for languages and charsets are somewhat
2041 large, so the time spent scanning them on each request is
2042 significant. Replacing the tables with hash tables provides
2043 a nice speedup. [Brian Pane <bpane@pacbell.net>]
2045 *) Add two functions to allow modules to access random parts of the
2046 scoreboard. This allows modules compiled for one MPM to access the
2047 scoreboard, even if it the server was compiled for another MPM.
2048 [Harrie Hazewinkel <harrie@covalent.net>]
2050 Changes with Apache 2.0.20
2052 *) Fix problem in content-length filter where the filter would
2053 buffer all the output from a CGI before sending any bytes
2054 down the filter stack to the network. This problem would cause
2055 significant memory consumption if the CGIs generated
2056 lots of bytes. [Bill Stoddard]
2058 *) Get non-blocking CGI pipe reads working with the bucket brigades.
2061 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
2064 *) Fix a bug in the threaded MPM that would cause it to kill off all
2065 workers immediately after starting if the number of workers started
2066 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
2068 Changes with Apache 2.0.19
2070 *) Fix problem with threaded MPM. The problem was that if each child
2071 process was busy serving a single long-lived request and the server
2072 was sent a graceful restart signal, the server would stop serving
2073 requests. This would happen because each child process would wait to
2074 die until the last thread was done, and the parent wouldn't spawn any
2075 new children until a process died. Now, the parent looks at the fact
2076 that the children are dying gracefully, and starts new children.
2077 Those new children only start enough threads to compliment the number
2078 of threads in the other child process that shares the same spot in
2079 the scoreboard. In this way, we make sure to never go over
2080 MaxClients. [Ryan Bloom]
2082 *) modified mod_negotiation and mod_autoindex to speed up by almost a
2083 factor of two on apr_dir_read()-enhanced platforms, such as Win32
2084 and OS2, by calling ap_sub_request_lookup_dirent() with the results
2085 already provided by apr_dir_read(). [William Rowe]
2087 *) mod_file_cache is now more robust to filtering and serves requests
2088 slightly more efficiently. [Cliff Woolley]
2090 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
2091 Module was calling ap_rwrite() followed by ap_rflush() but the
2092 served content was not being displayed in the browser. Inspection
2093 of the output stream revealed that the first data chunk was
2094 missing the trailing CRLF required by the RFC. [Bill Stoddard]
2096 *) apxs no longer generates ap_send_http_header() in the example handler
2098 *) Fix an ab problem which could cause a divide-by-zero exception
2099 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
2100 [Ian Holsman <ianh@cnet.com>]
2102 *) Solve case-insensitive platforms' confusion about negotiated
2103 filenames, allowing files of differnt case to match in choosing
2104 the document to serve. [William Rowe]
2106 *) Fix brokenness when ThreadsPerChild is higher than the built-in
2107 limit. We left ap_threads_per_child at the higher value which
2108 led to segfaults when doing certain scoreboard operations.
2111 *) Fix seg faults and/or missing output from mod_include. The
2112 default_handler was using the subrequest pool for files and
2113 MMAPs, even though the associated APR structures typically
2114 live longer than the subrequest. [Greg Ames]
2116 *) Extend mod_setenvif to support specifying regular expressions
2117 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
2118 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
2119 will cause HAVE_TS to be set if any of the request headers begins
2120 with "TS" and has a value that begins with any character in the
2121 set [a-z]. [Bill Stoddard]
2123 *) httpd children now re-bind themselves to a random CPU on
2124 multiprocessor systems on AIX via bindprocessor() in 2.0.
2125 [Victor J. Orlikowski]
2127 *) Fix htdigest. It would go into a loop in getline when adding
2128 a second user. [Bill Stoddard]
2130 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
2132 *) Automatically generate httpd.exp for AIX.
2133 DSOs now work again on AIX in 2.0
2134 [Victor J. Orlikowski]
2136 *) Add a new request hook, error_log. This phase allows modules
2137 to act on the error log string _after_ it has been written
2138 to the error log. The goal for this hook is to allow monitoring
2139 modules to send the error string to the monitoring agent.
2142 *) Modify mod_echo to make it use filters for input and output.
2143 [Ryan Morgan <rmorgan@covalent.net>]
2145 *) Extend mod_headers to support conditional driven Header
2146 add, append and set. Use SetEnvIf to set an envar and conditionally
2147 add/append/set headers based on this envar thusly:
2149 SetEnvIf TSMyHeader value HAVE_TSMyHeader
2150 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
2152 If the request contains header "TSMyHeader: value" then header
2153 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
2156 *) Extend mod_headers to support using format specifiers on Header
2157 add, append and set header values. Two format specifiers are supported:
2159 %t - reports, in UTC microseconds since the epoch, when the
2160 request was received.
2162 %D - reports the time, in microseconds, between when the request was
2163 received and the response sent.
2166 Header add MyHeader "This request served in %D microseconds. %t"
2168 results in a header being added to the response that looks like this:
2170 MyHeader: This request served in D=5438 microseconds. t=991424704447256
2174 *) Fix reset_filter(). We need to be careful how we remove filters.
2175 If we set r->output_filters to NULL, we also have to reset the
2176 connection's filters. [John Sterling]
2178 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
2180 *) Add a check to ap_die() to make sure the filter stack is sane and
2181 contains the correct basic filters when an error occurs. This fixes
2182 a problem where headers are not being sent on error. [John Sterling]
2184 *) New Header directive 'echo' option. "Header echo regex" will
2185 cause any headers received on the request that match regex to be
2186 echoed to (included in) the response headers.
2189 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
2190 This prevented the inclusion of apr_compat.h. PR #7773
2191 [Oleg Broytmann <phd@phd.pp.ru>]
2193 *) Moved util_uri to the apr-util library. This required a bunch of
2194 apr_name changes for the uri utility functions. [Justin Erenkrantz]
2196 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
2197 insert_filter phase so that other filters are not bypassed by default.
2200 *) Reimplement mod_headers as an output filter. mod_headers can now
2201 add custom headers to inbound requests using the RequestHeader directive
2202 and to responses using the same old Header directive. [Graham Leggett]
2204 Changes with Apache 2.0.18
2206 *) Fix command-line processing so that if a bad argument is specified
2207 Apache will exit. [Jeff Trawick]
2209 *) Change the make targets and rules to be consistent in all of the
2210 Apache-owned source trees. [Roy Fielding]
2212 *) Fix processing of the TRACE method. Previously we passed bogus
2213 parms to form_header_field() and it overlaid some vhost structures,
2214 resulting in a segfault in check_hostalias().
2215 [Greg Ames, Jeff Trawick]
2217 *) Win32: Add support for reliable piped logs. If the logging process
2218 goes down, Apache will automatically restart it. This function has
2219 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
2222 *) Do not start piped log processes during the config file
2223 preflight. This change also circumvents a problem on
2224 Windows where the rotatelog processes created during preflight
2225 was not getting cleaned up properly.
2228 *) add "Request Phase Participation" info to mod_info
2231 *) Make first phase changes to the scoreboard data structures in
2232 preparation for the rewriting of the scoreboard per my posted
2233 design notes. [Paul J. Reder]
2235 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
2236 and apr-util, allow it to be overridden by the configure command-line
2237 (default="--silent") and introduce LT_LDFLAGS to replace what we were
2238 formerly abusing as LTFLAGS. [Roy Fielding]
2240 *) Clean up the reporting of incorrect closing container tags.
2241 [Barrie Slaymaker <barries@slaysys.com>]
2243 *) Simplify the configure process by moving all libtool stuff to APR
2244 and moving hints.m4 inline. [Roy Fielding]
2246 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
2247 of functions used by mod_proxy for export in the DLL
2248 [Ian Holsman <IanH@cnet.com>]
2250 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
2251 request body from its stdin but no reqest body is being written to
2252 the cgi. [Jeff Trawick]
2254 *) mod_log_config: %c connection status incorrectly logged
2255 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
2258 *) Get mod_cern_meta working under Windows
2261 *) Create Files, and thus MMAPs, out of the request pool, not the
2262 connection pool. This solves a small resource leak that had us
2263 not closing files until a connection was closed. In order to do
2264 this, at the end of the core_output_filter, we loop through the
2265 brigade and convert any data we have into a single HEAP bucket
2266 that we know will survive clearing the request_rec.
2267 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
2270 *) Completely revamp configure so that it preserves the standard make
2271 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
2272 the configure additions to EXTRA_* variables. Also, allow the user
2273 to specify NOTEST_* values for all of the above, which eliminates the
2274 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
2275 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
2276 avoid pointless duplications. Fix the order in which flags are given
2277 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
2278 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
2279 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
2280 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
2282 *) Get mod_tls to compile/work better on Windows. PR #7612
2283 [Bernhard Schrenk <b.schrenk@improx.com>]
2285 *) Fix shutdown/restart hangs in the threaded MPM.
2286 [Jeff Trawick, Greg Ames, Ryan Bloom]
2288 *) Removed the keptalive boolean from conn_rec because it is now only
2289 used by a single routine and can be replaced by a local variable.
2290 [Greg Stein, Ryan Bloom, Roy Fielding]
2292 *) Patch prefork to put enough of the signal processing back in so that
2293 signals are all handled properly now. The previous patch fixed the
2294 deadlock race condition, but broke the user directed signal handling.
2295 This fixes it to work the way it did before my previous prefork patch
2296 (primarily, SIGTERM is now working).
2298 *) Change how input filters decide how much data is returned to the
2299 higher filter. We used to use a field in the conn_rec, with this
2300 change, we use an argument to ap_get_brigade to determine how much
2301 data is retrieved. [Ryan Bloom]
2303 *) Fix seg fault at start-up introduced by Ryan's change to enable
2304 modules to specify their own logging tags. mod_log_config
2305 registers an optional function, ap_register_log_handler().
2306 ap_register_log_handler() was being called by http_core before
2307 the directive hash table was created. This patch creates the
2308 directive hash table before ap_register_log_handler() is
2309 registered as an optional function.
2310 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2312 *) Add ap_set_int_slot() function
2313 [John K. Sterling <sterling@covalent.net>]
2315 *) Under certain circumstances, Apache did not supply the
2316 right response headers when requiring authentication.
2317 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
2318 (This is a port of the change that went into Apache 1.3.19.)
2320 *) Allow modules to specify their own logging tags. This basically
2321 allows a module to tell mod_log_config that when %x is encountered
2322 a specific function should be called. Currently, x can be any single
2323 character. It may be more useful to make this a string at some point.
2326 Changes with Apache 2.0.17
2328 *) If a higher-level filter handles the the byterange aspects of a
2329 request, then the byterange filter should not try to redo the
2330 work. The most common case of this happening, is a byterange
2331 request going through the proxy, and the origin server handles
2332 the byterange request. The proxy should ignore it.
2333 [Graham Leggett <minfrin@sharp.fm>]
2335 *) Changed the threaded mpm to have child_main join to each of the
2336 worker threads to make sure the kids are all gone before child_main
2337 exits after a signal (cleanup from perform_idle_server_maintenance).
2338 This is an extension of Ryans recent commit to make the child_main
2341 *) Add more options to the ap_mpm_query function. This also allows MPMs to
2342 report if their threads are dynamic or static. Finally, this also
2343 implements a new API, ap_show_mpm, which returns the MPM that was
2344 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
2346 *) Do not install the binaries from the support directory twice.
2347 [jun-ichiro hagino <itojun@iijlab.net>]
2349 *) The ap_f* functions should flush data to the filter that is passed
2350 in, not the the filter after the one passed in.
2351 [Ryan Morgan <rmorgan@covalent.net>]
2353 *) Make ab work again by changing its native types to apr types and formats.
2354 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2356 *) Move the byterange filter and all of the supporting functions back
2357 to the HTTP module. The byterange filter turned out to be very
2358 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
2360 *) Make clean, distclean, and extraclean consistently according to the
2361 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2363 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
2364 This may have been causing problems stopping processes in the threaded
2367 *) Fix content-length in mod_negotiation to a long int representation.
2370 *) Remove BindAddress from the default config file.
2371 [giles@nemeton.com.au]
2373 *) Allow module authors to add a module to their Apache build using
2374 --with-module, without re-running buildconf. The syntax is:
2375 --with-module=module_type:/path/to/module.c
2376 The configure script will copy the module.c file to
2377 modules/module_type, and it will be added to the relevant Makefiles.
2378 currently, this only works for static modules. [Ryan Bloom]
2380 *) Changes required to make prefork clean up idle children properly.
2381 There was a window during which a starting worker deadlocks when
2382 an idle cleanup arrives before it completes init. Apache then keeps
2383 trying to cleanup the same deadlocked worker forever (until higher
2384 pids come along, but it still will never reduce below the deadlocked
2385 pid). Thus the number of children would not reduce to the correct
2386 idle level. [Paul J. Reder]
2388 Changes with Apache 2.0.16
2390 *) Change the default installation directory to /usr/local/apache2,
2391 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
2393 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
2396 *) Get MaxRequestsPerChild working with the Windows MPM.
2399 *) Make generic hooks to work, with mod_generic_hook_import/export
2400 experimental modules. [Ben Laurie, Will Rowe]
2402 *) Fix segfaults for configuration file syntax errors such as
2403 "<Directory>" followed by "</Directory" and
2404 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
2406 *) Cleanup the --enable-layout option of configure. This makes
2407 us use a consistent location for the config.layout file, and it
2408 makes configure more portable.
2409 [jun-ichiro hagino <itojun@iijlab.net>]
2411 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
2412 csv/gnuplot format, rudimentary ssl support and various other tweaks
2413 to make results more true to what is measured. The upshot of this it
2414 turns out that 'ab' has often underreported the true performance of
2415 apache. Often by a order of magnitude :-) See talk/paper of Sander
2416 Temme at April ApacheCon 2001 for details.
2417 [Dirk-Willem van Gulik]
2419 *) Clean up mod_cgid's temporary request pool. Besides fixing a
2420 storage leak this ensures that some unnecessary pipes are closed.
2423 *) Performance: Add quick_handler hook. This hook is called at the
2424 very beginning of the request processing before location_walk,
2425 translate_name, etc. This hook is useful for URI keyed content
2426 caches like Mike Abbott's Quick Shortcut Cache.
2429 *) top_module global variable renamed to ap_top_module [Perl]
2431 *) Move ap_set_last_modified to the core. This is a potentially
2432 controversial change, because this is kind of HTTP specific. However
2433 many protocols should be able to take advantage of this kind of
2434 information. I expect that headers will need one more layer of
2435 indirection for multi-protocol work, but this is a small step in
2436 the right direction. [Ryan Bloom]
2438 *) Enable mod_status by default. This matches what Apache 1.3 does.
2441 *) Add a ScriptSock directive to the default config file. This is
2442 only enabled when mod_cgid is used.
2443 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2445 Changes with Apache 2.0.15
2447 *) Untangled the buildconf script and eliminated the need for build's
2448 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
2449 libtool muck that is now under srclib/apr/build. [Roy Fielding]
2451 *) Win32: Don't accept more connections than we have worker threads
2455 *) Fix bug in the Unix threaded.c MPM that allowed child processes
2456 to fork() new child processes.
2459 *) Fix a major security problem with double-reverse lookup checking.
2460 Previously, a client connecting over IPv4 would not be matched
2461 properly when the server had an IPv6 listening socket. PR #7407
2462 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
2464 *) Change the way the beos MPM handles polling to allow it to stop and
2465 restart. Problem was the sockets being polled were being reset by
2466 the select call, so once it had accepted a connection it was no
2467 longer listening on the UDP socket we use for shutdown instructions.
2468 APR needs to be altered, patch on it's way. [David Reid]
2470 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
2471 on error exit from ap_getline(). Some other code got upset because
2472 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
2474 *) Handle ap_discard_request_body() being called more than once.
2475 [Greg Ames, Jeff Trawick]
2477 *) Get rid of an inadvertent close of file descriptor 2 in
2478 mod_mime_magic. [Greg Ames, Jeff Trawick]
2480 *) Add a hook, create_request. This hook allows modules to modify
2481 a request while it is being created. This hook is called for all
2482 request_rec's, main request, sub request, and internal redirect.
2483 When this hook is called, the the r->main, r->prev, r->next
2484 pointers have been set, so modules can determine what kind of
2485 request this is. [Ryan Bloom]
2487 *) Cleanup the build process a bit more. The Apache configure
2488 script no longer creates its own helper scripts, it just
2490 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2492 *) Stop the forced downgrade of the connection to HTTP/1.0 for
2493 proxy requests. [Graham Leggett]
2495 *) Avoid using sscanf to determine the HTTP protocol number in
2496 the common case because sscanf is a performance hog. From
2497 Mike Abbot's Accelerating Apache patch number 6.
2498 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
2500 *) Fix a security exposure in mod_access. Previously when IPv6
2501 listening sockets were used, allow/deny-from-IPv4-address rules
2502 were not evaluated properly (PR #7407). Also, add the ability to
2503 specify IPv6 address strings with optional prefix length on Allow
2504 and Deny. [Jeff Trawick]
2506 *) Enhance rotatelogs so that a UTC offset can be specified, and
2507 the logfile name can be formatted using strftime(3). (Brought
2508 forward from 1.3.) [Ken Coar]
2510 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
2511 DuplicateHandle on an IOCompletionPort (a practice which
2512 MS "discourages"). The new model does not rely on associating
2513 the completion port with the listening sockets, thus the
2514 completion port can be completely managed within the child
2515 process. A dedicated thread accepts connections off the network,
2516 then calls PostQueuedCompletionStatus() to wake up worker
2517 threads blocked on the completion port.
2520 *) Bring forward the --suexec-umask option which allows the
2521 builder to preset the umask for suexec processes. [Ken Coar]
2523 *) Add a -V flag to suexec, which causes it to display the
2524 compile-time settings with which it was built. (Only
2525 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
2527 *) Mod_include should always unset the content-length if the file is
2528 going to be passed through send_parsed_content. There is no to
2529 determine if the content will change before actually scanning the
2530 entire content. It is far safer to just remove the C-L as long
2531 as we are scanning it. [Ryan Bloom]
2533 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
2534 request and not Proxy-Authenticate.
2535 [Graham Leggett <minfrin@sharp.fm>]
2537 Changes with Apache 2.0.14
2539 *) Fix content-length computation. We ONLY compute a content-length if
2540 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
2541 or we already have all the data. [Ryan Bloom]
2543 *) Report unbounded containers in the config file. Previously, a typo
2544 in the </container> directive could result in the rest of the config
2545 file being silently ignored, with undesired defaults used.
2548 *) Make the old_write filter use the ap_f* functions for the buffering.
2551 *) Move more code from the http module into the core server. This
2552 is core code, basically the default handler, the default input
2553 and output filters, and all of the core configuration directives.
2554 All of this code is required in order for the server to work, with or
2555 without HTTP. The server is closer to working without the HTTP
2556 module, although there is still more to do. [Ryan Bloom]
2558 *) Fix a number of SGI compile warnings throughout the server. Fix some
2559 bad parameters to apr_bucket_read(). Fix a bad statement in
2560 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
2561 consistently; we were mixing apr_time_t and time_t in invalid ways
2562 before. In load_file(), call apr_dso_error() instead of
2563 apr_strerror() so that we get a more specific string on some platforms.
2564 PR #6980 [Jeff Trawick]
2566 *) Allow modules to query the MPM about it's execution profile. This
2567 query API can and should be extended in the future, but for now,
2568 max_daemons, and threading or forking is a very good start.
2569 [Jon Travis <jtravis@covalent.net>]
2571 *) Modify mod_include to send blocks of data no larger than 9k.
2572 Without this, mod_include will wait until the whole file is parsed,
2573 or the first tag is found to send any data to the client.
2574 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2576 *) Fix mod_info, so that <Directory> and <Location> directives are
2577 not displayed twice when displaying the current configuration.
2578 [Ryan Morgan <rmorgan@covalent.net>]
2580 *) Add config directives to override DEFAULT_ERROR_MSG and
2581 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
2582 [Dan Rench <drench@xnet.com>]
2584 *) Get mod_info building and loading on Win32. [William Rowe]
2586 *) Begin to move protocol independant functions out of mod_http. The goal
2587 is to have only functions that are HTTP specific in the http directory.
2590 Changes with Apache 2.0.13
2592 *) Don't assume that there will always be multiple calls to the byterange
2593 filter. It is possible that we will need to do byteranges with only
2594 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
2596 *) Move the error_bucket definition from the http module to the
2597 core server. Every protocol will need this ability, not just
2600 Changes with Apache 2.0.12
2602 *) Modify mod_file_cache to save pre-formatted strings for
2603 content-length and last-modified headers for performance.
2604 [Mike Abbot <mja@trudge.engr.sgi.com>]
2606 *) Namespace protect IOBUFSIZ since it is exposed in the API.
2607 [Jon Travis <jtravis@covalent.net>]
2609 *) Use "Basic" authentication instead of "basic" in ab, as the spec
2610 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
2612 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
2613 without ever filling it out. This fixes PR 7271.
2614 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
2615 Cliff Woolley <cliffwoolley@yahoo.com>]
2617 *) Add a couple of GCC attribute tags to printf style functions.
2618 [Jon Travis <jtravis@covalent.net>]
2620 *) Add the correct language tag for interoperation with the Taiwanese
2621 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
2623 *) Migrate the perchild MPM to use the new apr signal child, and
2624 APR thread functions. [Ryan Bloom]
2626 *) Close one copy of the CGI's stdout before creating the new process.
2627 The CGI will still have stdout, because we have already dup'ed it.
2628 This keeps Apache from waiting forever to send the results of a CGI
2629 process that has forked a long-lived child process.
2630 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2632 *) Remove the rest of the pthreads functions from the threaded MPM.
2633 This requires the APR support for a signal thread that was just
2636 *) Make mod_dir use a fixup for sending a redirect to the browser.
2637 Before this, we were using a handler, which doesn't make much
2638 sense, because the handler wasn't generating any data, it would
2639 either return a redirect error code, or DECLINED. This fits the
2640 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
2642 *) Make the threaded MPM use APR threads instead of pthreads.
2645 *) Get mod_tls to the point where it actually appears to work in all cases.
2648 *) implement --enable-modules and --enable-mods-shared for "all" and
2649 "most". [Greg Stein]
2651 *) Move the threaded MPM to use APR locks instead of pthread locks.
2654 *) Rename mpmt_pthread to threaded. This is more in line with the
2655 fact that mpmt_pthread shouldn't be using pthreads directly, and
2656 it is a smaller name that doesn't tie into anything.
2659 *) Rename the module structures so that the exported symbol matches
2660 the file name, and it is easier to automate the installation
2661 process (generating LoadModule directives from the module filenames).
2664 *) Remove the coalesce filter. With the ap_f* functions, this filter
2665 is no longer needed. [Ryan Bloom]
2667 Changes with Apache 2.0.11
2669 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
2670 added feature of allowing a uid/gid per child process. If no
2671 uid/gid is specified, then Perchild behaves exactly like dexter.
2674 *) Get perchild building again. [Ryan Bloom]
2676 *) Don't disable threads just because we are using the prefork MPM.
2677 If somebody wants to compile without threads, they must now add
2678 --disable-threads to the configure command line. [Ryan Bloom]
2680 *) Begin to move the calls to update_child_status into common code, so
2681 that each individual MPM does not need to update the scoreboard itself.
2684 *) Allow mod_tls to compile under Unix boxes where openssl has been
2685 installed to the system include files.
2686 [Gomez Henri <new-httpd@slib.fr>]
2688 *) Cleanup the mod_tls configure process. This should remove any need
2689 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
2690 configure doesn't check that yet. [Ryan Bloom]
2692 *) Add a very early prototype of SSL support (in mod_tls.c). It is
2693 vital that you read modules/tls/README before attempting to build
2696 *) Fix a potential seg fault on all platforms. David Reid fixed this
2697 on BEOS, but the problem could happen anywhere, so we don't want
2698 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
2700 *) Add new LogFormat directive, %D, to log time it takes to serve a
2701 request in microseconds. [Bill Stoddard]
2703 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
2704 SetOutputFilter. This corresponds nicely with the other Set
2705 directives, which operate on containers while the Add* directives
2706 tend to work directly on extensions. [Ryan Bloom]
2708 *) Cleanup the header handling a bit. This uses the apr_brigade_*
2709 functions for the buffering so that we don't need to compute
2710 the length of the headers before we actually create the header
2711 buffer. [Ryan Bloom]
2713 *) Allow filters to buffer data using the ap_f* functions. These have
2714 become macros that resolve directly to apr_brigade_*.
2717 *) Get the Unix MPM's to do a graceful restart again. If we are going
2718 to register a cleanup with ap_cleanup_scoreboard, then we have to
2719 kill the cleanup with the same function, and that function can't be
2720 static. [Ryan Bloom]
2722 *) Install all required header files. Without these, it was not
2723 possible to compile some modules outside of the server.
2726 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
2727 forward from 1.3 to 2.0, we missed a single line, which broke regex
2728 aliases. [Ryan Bloom]
2730 *) We have a poor abstraction in the protocol. This is a temporary
2731 hack to fix the bug, but it will need to be fixed for real. If
2732 we find an error while sending out a custom error response, we back
2733 up to the first non-OK request and send the data. Then, when we send
2734 the EOS from finalize_request_protocol, we go to the last request,
2735 to ensure that we aren't sending an EOS to a request that has already
2736 received one. Because the data is sent on a different request than
2737 the EOS, the error text never gets sent down the filter stack. This
2738 fixes the problem by finding the last request, and sending the data
2739 with that request. [Ryan Bloom]
2741 *) Make the server status page show the correct restart time, and
2742 thus the proper uptime. [Ryan Bloom]
2744 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
2745 should reduce the amount of duplicate code that is required to
2746 create CGI processes.
2747 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2749 *) ap_new_connection() closes the socket and returns NULL if a socket
2750 call fails. Usually this is due to a connection which has been
2751 reset. [Jeff Trawick]
2753 *) Move the Apache version information out of httpd.h and into release.h.
2754 This is in preparation for the first tag with the new tag and release
2755 system. [Ryan Bloom]
2757 *) Begin restructuring scoreboard code to enable adding back in
2758 the ability to use IPC other than shared memory.
2759 Get mod_status working on Windows again. [Bill Stoddard]
2761 *) Make mod_status work with 2.0. This will work for prefork,
2762 mpmt_pthread, and dexter. [Ryan Bloom]
2764 *) Correct a typo in httpd.conf.
2765 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
2767 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
2769 *) Get the correct IP address if ServerName isn't set and we can't
2770 find a fully-qualified domain name at startup.
2771 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
2773 *) Make mod_cgid work with SuExec. [Ryan Bloom]
2775 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
2776 'extra' stat's for user/group since they should never occur, and now
2777 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
2778 volumes. [William Rowe]
2780 *) Adopt apr features to simplify mod_includes. This changes the
2781 behavior of the USER_NAME variable, unknown uid's are now reported
2782 as USER_NAME="<unknown>" rather than the old user#000 result.
2783 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
2785 *) Adopt apr features for simplifing mod_userdir, and accept the new
2786 Win32/OS2 exceptions without hiccuping. [William Rowe]
2788 *) Replace configure --with-optim option by using and saving the
2789 environment variable OPTIM instead. This is needed because configure
2790 options do not support multiple flags separated by spaces.
2793 *) Fix some byterange handling. If we get a byte range that looks like
2794 "-999999" where that is past the end of the file, we should return
2795 a PARTIAL CONTENT status code, and return the whole file as one big
2796 byterange. This matches the 1.3 handling now. [Ryan Bloom]
2798 *) Make the error bucket a real meta-data bucket. This means that the
2799 bucket length is 0, and a read returns NULL data. If one of these
2800 buckets is passed down after the headers are sent, this data will
2801 just be ignored. [Greg Stein]
2803 *) The prefork MPM wasn't killing child processes correctly if a restart
2804 signal was received while the process was serving a request. The child
2805 process would become the equivalent of a second parent process. If
2806 we break out of the accept loop, then we need to do die after cleaning
2807 up after ourselves. [Ryan Bloom]
2809 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
2810 restarts. [Ryan Bloom]
2812 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
2813 the most optimal APR_FINFO_wanted bits. This spares Win32 from
2814 performing very expensive owner, group and permission lookups
2815 and allows the server to function until these apr_finfo_t fields
2816 are implemented under Win32. [William Rowe]
2818 *) Support for typedsafe optional functions - that is functions exported by
2819 optional modules, which, therefore, may or may not be present, depending
2820 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
2821 for sample code. [Ben Laurie]
2823 *) filters can now report an HTTP error to the server. This is done
2824 by sending a brigade where the first bucket is an error_bucket.
2825 This bucket is a simple bucket that stores an HTTP error and
2826 a string. Currently the string is not used, but it may be needed
2827 to output an error log. The http_header_filter will find this
2828 bucket, and output the error text, and then return
2829 AP_FILTER_ERROR, which informs the server that the error web page
2830 has already been sent. [Ryan Bloom]
2832 *) If we get an error, then we should remove all filters except for
2833 those critical to serving a web page. This fixes a bug, where
2834 error pages were going through the byterange filter, even though
2835 that made no sense. [Ryan Bloom]
2837 *) Relax the syntax checking of Host: headers in order to support
2838 iDNS. PR#6635 [Tony Finch]
2840 *) Cleanup the byterange filter to use the apr_brigade_partition
2841 and apr_bucket_copy functions. This removes a lot of very messy
2842 code, and hopefully makes this filter more stable.
2845 *) Remove AddModule and ClearModuleList directives. Both of these
2846 directives were used to ensure that modules could be enabled
2847 in the correct order. That requirement is now gone, because
2848 we use hooks to ensure that modules are in the correct order.
2851 *) When SuExec is specified, we need to add it to the list of
2852 targets to be built. If we don't, then any changes to the
2853 configuration won't affect SuExec, unless 'make suexec' is
2854 specifically run. [Ryan Bloom]
2856 *) Cleaned out open_file from mod_file_cache, as apr now accepts
2857 the APR_XTHREAD argument to open a file for consumption by
2858 parallel threads on win32. [William Rowe]
2860 *) Correct a bug in determining when we follow symlinks. The code
2861 expected a stat -1 result, not an apr_status_t positive error.
2862 Also check if the APR_FINFO_USER fields are valid before we
2863 follow the link. [William Rowe]
2865 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
2866 mpm_common.c. These functions are only valid on some platforms,
2867 so they should not be in the main-line code. [Ryan Bloom]
2869 *) Remove ap_chdir_file(). This function is not thread-safe,
2870 and nobody is currently using it. [Ryan Bloom]
2872 *) Do not try to run make depend if there are no .c files in the
2873 current directory, doing so makes `make depend` fail.
2876 *) Update highperformance.conf to work with either prefork or
2877 pthreads mpms. [Greg Ames]
2879 *) Stop checking to see if this is a pipelined request if we know
2880 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
2881 This keeps us from making an extra read call when serving a 1.0
2882 request. [Ryan Bloom and Greg Stein]
2884 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
2885 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
2886 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
2888 *) Fix the RFC number mentioned when complaining about a missing
2889 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
2891 *) Fix an endless loop in ab which occurred when ab was posting
2892 and the server dropped the connection unexpectedly.
2895 *) Fix a segfault while handling request bodies in ap_http_filter().
2896 This problem has been seen with mod_dav usage as well as with
2897 requests where the body was just being discarded. [Jeff Trawick]
2899 *) Some adjustment on the handling and automatic setting (via
2900 hints.m4) of various compilation flags (eg: CFLAGS). Also,
2901 add the capability to specify flags (NOTEST_CFLAGS and
2902 NOTEST_LDFLAGS) which are used to compile Apache, but
2903 not used during the configuration process. Useful for
2904 flags like "-Werror". [Jim Jagielski]
2906 *) Stop using environment variables to force debug mode or
2907 no detach. We now use the -D command line argument to
2908 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
2909 [Greg Stein, Ryan Bloom]
2911 *) Change handlers to use hooks. [Ben Laurie]
2913 *) Stop returning copies of filenames from both apr_file_t and
2914 apr_dir_t. We pstrdup the filenames that we store in the
2915 actual structures, so we don't need to pstrdup the strings again.
2918 *) mod_cgi: Fix some problems where the wrong error value was being
2919 traced. [Jeff Trawick]
2921 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
2924 *) Add generic hooks. [Ben Laurie]
2926 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
2928 *) Fix a segfault caused by mod_ext_filter when the external filter
2929 program does not exist. [Jeff Trawick]
2931 *) Fix an output truncation error when on an HTTP >= 1.0 request an
2932 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
2933 was served through mod_charset_lite (or anything else that would
2934 create a transient bucket in this size range). ap_bucket_make_heap()
2935 silently failed (fixed), transient_setaside() discovered it, but
2936 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
2938 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
2939 is that some browsers send extra lines at the end of POST requests, and
2940 we don't want to delay sending data back to the user just because the
2941 browser isn't well behaved. [Ryan Bloom]
2943 *) Get SuEXEC working again. We can't send absolute paths to suExec
2944 because it refuses to execute those programs. SuEXEC also wasn't
2945 always recognizing configuration changes made using the autoconf
2948 *) Allow the buildconf process to find the config.m4 files in the correct
2949 order. Basically, we can now name config.m4 files as config\d\d.m4,
2950 and we will sort them correctly when inserting them into the build
2951 process. [Ryan Bloom]
2953 *) Get mod_cgid to use apr calls for creating the actual CGI process.
2954 This also allows mod_cgid to use ap_os_create_priviledged_process,
2955 thus allowing for SuExec execution from mod_cgid. Currently, we do
2956 not support everything that standard SuExec supports, but at least
2957 it works minimally now. [Ryan Bloom]
2959 *) Allow SuExec to be configured from the ./configure command line.
2962 *) Update some of the docs in README and INSTALL to reflect some of
2963 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
2965 *) If we get EAGAIN returned from the call to apr_sendfile, then we
2966 need to call sendfile again. This gets us serving large files
2967 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
2969 *) Get the support programs building cleanly again.
2970 [Cliff Woolley <cliffwoolley@yahoo.com>]
2972 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
2973 current directory logic now backs up over bin/ to determine the
2974 server root from the Apache.exe path.
2976 *) Apache/Win32 now follows the standard conventions of mod_foo.so
2977 loadable modules, dynamic libs are all named libfoo.dll, and the
2978 makefile.win populates the include, lib and libexec directories.
2980 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
2981 Apache gets IPv6 listening sockets by default. Additionally, the
2982 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
2983 numeric address strings (e.g., "Listen [fe80::1]:8080").
2986 *) Modify the install directory layout. Modules are now installed in
2987 modules/. Shared libraries should be installed in libraries/, but
2988 we don't have any of those on Unix yet. All install directories
2989 are modifyable at configure time. [Ryan Bloom]
2991 *) Install all header files in the same directory on Unix. [Ryan Bloom]
2993 *) Get the functions in server/linked into the server, regardless of
2994 which modules linked into the server. This uses the same hack
2995 for Apache that we use for APR and apr-util to ensure all of the
2996 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
2997 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
2998 the scripts a bit easier.
3001 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
3002 on the query, and remove IPv4 dependencies. [Jeff Trawick]
3004 *) Get all of the auth modules to the point that they will install and
3005 be loadable into the server. Our new build/install mechanism expects
3006 that all modules will have a common name format. The auth modules
3007 didn't use that format, so we didn't install them properly.
3010 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
3011 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
3013 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
3015 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
3016 after the end of the response. [Ryan Bloom]
3018 *) Get byterange requests working with responses that do not have a
3019 content-length. Because of the way byterange requests work, we have to
3020 have all of the data before we can actually do the byterange, so we
3021 can compute the content-length in the byterange filter.
3024 *) Get exe CGI's working again on Windows.
3027 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
3028 they keep track of whether or not their post config hook has been
3029 called before. Instead of a static variable (which is replaced when
3030 the DSO is loaded a second time), use userdata in the process pool.
3033 Changes with Apache 2.0a9
3035 *) Win32 now requires perl to complete the final install step for users
3036 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
3037 and installs the conf, htdocs and htdocs/manual directories.
3040 *) Make mod_include use a hash table to associate directive tags with
3041 functions. This allows modules to implement their own SSI tags easily.
3042 The idea is simple enough, a module can insert it's own tag and function
3043 combination into a hash table provided by mod_include. While mod_include
3044 parses an SSI file, when it encounters a tag in the file, it does a
3045 hash lookup to find the function that implements that tag, and passes
3046 all of the relevant data to the function. That function is then
3047 responsible for processing the tag and handing the remaining data back
3048 to mod_include for further processing.
3049 [Paul J. Reder <rederpj@raleigh.ibm.com>]
3051 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
3052 fewer parameters: the local and remote socket addresses were removed
3053 from the parameter list because all required information is available
3054 via the APR socket. [Jeff Trawick]
3056 *) Distribution directory structure reorganized to reflect a
3057 normal source distribution with external install targets.
3060 *) The MPMs that need multiple segments of shared memory now create
3061 two apr_shmem_t variables, one for each shared memory allocation.
3062 the problem is that we can't determine how much memory will be required
3063 for shared memory allocations once we try to allocate more than one
3064 variable. The MM code automatically aligns the shared memory allocations,
3065 so we end up needing to pad the amount of shared memory we want based
3066 on how many variables will be allocated out of the shared memory segment.
3067 It is just easier to create a second apr_shmem_t variable, and two
3068 shmem memory blocks.
3071 *) Cleanup the export list a bit. This creates a single unified list of
3072 functions exported by APR. The export list is generated at configure
3073 time, and that list is then used to generate the exports.c file.
3074 Because of the way the export list is generated, we only export those
3075 functions that are valid on the platform we are building on.
3078 *) Enable logging the cookie with mod_log_config
3079 [Sander van Zoest <sander@covalent.net>]
3081 *) Fix a segfault in mod_info when it reaches the end of the configuration.
3084 *) Added lib/aputil/ as a placeholder for utility functions which are not
3085 specific to the Apache HTTP Server (but do not make sense with APR).
3086 The first utility is "apu_dbm": a set of functions to work with DBM
3087 files. This first version can be compiled for SDBM or GDBM databases.
3090 *) Complete re-write of mod_include. This makes mod_include a filter that
3091 uses buckets directly. This has now served the FAQ correctly.
3092 [Paul Reder <rederpj@raleigh.ibm.com>]
3094 *) Allow modules to specify the first filter in a sub_request when
3095 making the sub_request. This keeps modules from having to change the
3096 output_filter immediately after creating the sub-request, and therefore
3097 skip the sub_req_output_filter. [Ryan Bloom]
3099 *) Update ab to accept URLs with IPv6 literal address strings (in the
3100 format described in RFC 2732), and to build Host header fields in
3101 the same format. This allows IPv6 literal address strings to be
3102 used with ab. This support has been tested against Apache 1.3 with
3103 the KAME patch, but Apache 2.0 does not yet work with this format
3104 of the Host header field. [Jeff Trawick]
3106 *) Accomodate an out-of-space condition in the piped logs and the
3107 rotatelogs.c code, and no longer churn log processes for this
3108 condition. [Victor J. Orlikowski]
3110 *) Add support for partial writes with apr_sendfile() to core_output_filter.
3113 Changes with Apache 2.0a8
3115 *) Add a directive to mod_mime so that filters can be associated with
3119 *) Get multi-views working again. We were setting the path_info
3120 field incorrectly if we couldn't find the specified file.
3123 *) Fix 304 processing. The core should never try to send the headers
3124 down the filter stack. Always, just setup the table in the request
3125 record, and let the header filter convert it to data that is ready
3129 *) More fixes for the proxy. There are still bugs in the proxy code,
3130 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
3134 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
3137 *) APR: Add new apr_getopt_long function to handle long options.
3138 [B. W. Fitzpatrick <fitz@red-bean.com>]
3140 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
3141 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
3142 hostname resolution/address string parsing and building
3143 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
3144 of one of the apr_sockaddr_t structures for a socket. Change
3145 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
3147 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
3148 I have proxied pages with it, cleanup will commence soon.
3151 *) Make the proxy work with filters. This isn't perfect, because we
3152 aren't dealing with the headers properly. [Ryan Bloom]
3154 *) Do not send a content-length iff the C-L is 0 and this is a head
3155 request. [Ryan Bloom]
3157 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
3158 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
3160 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
3162 *) Get the default_handler to stop trying to deal with HEAD requests.
3163 The idea is to let the content-length filter compute the C-L before
3164 we try to send the data. If we can get the C-L correctly, then we
3165 should send it in the HEAD response.
3168 *) The Header filter can now determine if a body should be sent based
3169 on r->header_only. The general idea of this is that if we delay
3170 deciding to send the body, then we might be able to compute the
3171 content-length correctly, which will help caching proxies to cache
3172 our data better. Any handler that doesn't want to try to compute
3173 the content-length can just send an EOS bucket without data and
3174 everything will just work.
3177 *) Add the referer to the error log if one is available.
3178 [Markus Gyger <mgyger@itr.ch>]
3180 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
3181 change, the root of the configuration tree has been exposed to modules
3183 [Ryan Morgan <rmorgan@covalent.net>]
3185 *) Get the core_output_filter to use the bucket interface directly.
3186 This keeps us from calling the content-length filter multiple times
3187 for a simple static request.
3190 *) We are sending the content-type correctly now.
3191 [Ryan Bloom and Will Rowe]
3193 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
3194 a bogus bytes-sent value when the only thing being sent was trailers
3195 and writev() returned an error (or EAGAIN). [Jeff Trawick]
3197 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
3198 hints file to determine which platforms define
3199 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3202 *) APR: add apr_get_home_directory() [Jeff Trawick]
3204 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
3206 *) Not all platforms have INADDR_NONE defined by default. Apache
3207 used to make this check and define INADDR_NONE if appropriate,
3208 but APR needs the check too, and I suspect other applications will
3209 as well. APR now defines APR_INADDR_NONE, which is always a valid
3210 value on all platforms.
3211 [Branko Èibej <brane@xbc.nu>]
3213 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
3214 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
3216 *) Relax the syntax checking of Host: headers in order to support
3217 iDNS. PR#6635 [Tony Finch]
3219 *) When reading from file buckets we convert to an MMAP if it makes
3220 sense. This also simplifies the default handler because the
3221 default handler no longer needs to try to create MMAPs.
3224 *) BUFF has been removed from the main server. The BUFF code will remain
3225 in the code until it has been purged from the proxy module as well.
3228 *) Byteranges have been completely re-written to be a filter. This
3229 has been tested, and I believe it is working correctly, but it could
3230 doesn't work for the Adobe Acrobat plug-in. The output almost matches
3231 the output from 1.3, the only difference being that 1.3 includes
3232 a content-length in the response, and this does not.
3235 *) APR read/write functions and bucket read functions now operate
3236 on unsigned integers, instead of signed ones. It doesn't make
3237 any sense to use signed ints, because we return the error codes,
3238 so if we have an error we should report 0 bytes read or written.
3241 *) Always compute the content length, whether it is sent or not.
3242 The reason for this, is that it allows us to correctly report
3243 the bytes_sent when logging the request. This also simplifies
3244 content-length filter a bit, and fixes the actual byte-reporing
3245 code in mod_log_config.c
3248 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
3249 it says, because it was only used by EOS and FLUSH buckets. Since
3250 neither of those are required at the end of a brigade, this was
3251 really signifying FLUSH_THE_DATA, but that can be determined better
3252 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
3253 buckets now return a length of 0, which is actually the amount of data
3254 read, so they make more sense.
3257 *) Allow the core_output_filter to save some data past the end of a
3258 request. If we get an EOS bucket, we only send the data if it
3259 makes sense to send it. This allows us to pipeline request
3260 responses. As a part of this, we also need to allocate mmap
3261 buckets out of the connection pool, not the request pool. This
3262 allows the mmap to outlive the request.
3265 *) Make blocking and non-blocking bucket reads work correctly for
3266 sockets and pipes. These are the only bucket types that should
3267 have non-blocking reads, because the other bucket types should
3268 ALWAYS be able to return something immediately.
3271 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
3272 server, but use Ctrl+Break to initiate a graceful restart
3273 instead of duplicating behavior. [John Sterling]
3275 *) Patch mod_autoindex to set the Last-Modified header based on
3276 the directory's mtime, and add the ETag header. [William Rowe]
3278 *) Merge the 1.3 patch to add support for logging query string in
3279 such a way that "%m %U%q %H" is the same as "%r".
3282 *) Port three log methods from mod_log_config 1.3 to 2.0:
3283 CLF compliant '-' byte count, method and protocol.
3286 *) Add a new LogFormat directive, %c, that will log connection
3287 status at the end of the response as follows:
3288 'X' - connection aborted before the response completed.
3289 '+' - connection may be kept-alive by the server.
3290 '-' - connection will be closed by the server.
3293 *) Expand APR for WinNT to fully accept and return utf-8 encoded
3294 Unicode file names and paths for Win32, and tag the Content-Type
3295 from mod_autoindex to reflect that charset if the the feature
3296 macro APR_HAS_UNICODE_FS is true. [William Rowe]
3298 *) Compute the content length (and add appropriate header field) for
3299 the response when no content length is available and we can't use
3300 chunked encoding. [Jeff Trawick]
3302 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
3303 so that content input filters get dechunked data when using
3304 the default handler. Also removed REQUEST_CHUNKED_PASS.
3307 *) Add mod_ext_filter as an experimental module. This module allows
3308 the administrator to use external programs as filters. Currently,
3309 only filtering of output is supported. [Jeff Trawick]
3311 *) Most Apache functions work on EBCDIC machines again, as protocol
3312 data is now translated (again). [Jeff Trawick]
3314 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
3315 the EBCDIC support. They are noops on ASCII machines, so this
3316 type of translation doesn't have to be surrounded by #ifdef
3317 CHARSET_EBCDIC. [Jeff Trawick]
3319 *) Fix mod_include. tag commands work again, and the server will
3320 send the FAQ again. This also allows mod_include to set aside
3321 buckets that include partial buckets.
3322 [Ryan Bloom and David Reid]
3324 *) Add suexec support back. [Manoj Kasichainula]
3326 *) Lingering close now uses the socket directly instead of using
3327 BUFF. This has been tested, but since all we can tell is that it
3328 doesn't fail, this needs to be really hacked on.
3331 *) Allow filters to modify headers and have those headers be sent to
3332 the client. The idea is that we have an http_header filter that
3333 actually sends the headers to the network. This removes the need
3334 for the BUFF to send headers.
3337 *) Charset translation: mod_charset_lite handles translation of
3338 request bodies. Get rid of the xlate version of ap_md5_digest()
3339 since we don't compute digests of filtered (e.g., translated)
3340 response bodies this way anymore. (Note that we don't do it at
3341 all at the present; somebody needs to write a filter to do so.)
3344 *) Input filters and ap_get_brigade() now have a input mode parameter
3345 (blocking, non-blocking, peek) instead of a length parameter.
3348 *) Update the mime.types file to the registered media types as
3349 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
3352 *) Namespace protect some macros declared in ap_config.h
3355 *) Support HTTP header line folding with input filtering.
3358 *) Mod_include works again. This should still be re-written, but at
3359 least now we can serve an SHTML page again.
3362 *) Begin to remove BUFF from the core. Currently, we keep a pointer
3363 to both the BUFF and the socket in the conn_rec. Functions that
3364 want to use the BUFF can, functions that want to use the socket,
3365 can. They point to the same place.
3368 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
3369 [Tomas "Ögren" <stric@ing.umu.se>]
3371 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
3372 associated pool goes away. (APR pipes on OS/2 were already had this
3373 logic.) This resolvs a fatal file descriptor leak with CGIs.
3376 *) The final line of the config file was not being read if there was
3377 no \n at the end of it. This was caused by apr_fgets returning
3378 APR_EOF even though we had read valid data. This is solved by
3379 making cfg_getline check the buff that was returned from apr_fgets.
3380 If apr_fgets return APR_EOF, but there was data in the buf, then we
3381 return the buf, otherwise we return NULL.
3384 *) Piped logs work again in the 2.0 series.
3387 *) Restore functionality broken by the mod_rewrite security fix:
3388 rewrite map lookup keys and default values are now expanded
3389 so that the lookup can depend on the requested URI etc.
3390 PR #6671 [Tony Finch]
3392 *) Tighten up the syntax checking of Host: headers to fix a
3393 security bug in some mass virtual hosting configurations
3394 that can allow a remote attacker to retrieve some files
3395 on the system that should be inaccessible. [Tony Finch]
3397 *) Add a pool bucket type. This bucket is used for data allocated out
3398 of a pool. If the pool is cleaned before the bucket is destroyed, then
3399 the data is converted to a heap bucket, allowing it to survive the
3403 *) Add a flush bucket. This allows modules to signal that the filters
3404 should all flush whatever data they currently have. There is no way
3405 to actually force them to do this, so if a filter ignores this bucket,
3406 that's life, but at least we can try with this.
3409 *) Add an output filter for sub-requests. This filter just strips the
3410 EOS bucket so that we don't confuse the main request's core output
3411 filter by sending multiple EOS buckets. This change also makes sub
3412 requests start to send EOS buckets when they are finished.
3415 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
3416 makes ap_bucket_destroy a return void, which is okay because it
3417 used to always return APR_SUCCESS, and nobody ever checked its
3418 return value anyway.
3419 [Cliff Woolley <cliffwoolley@yahoo.com>]
3421 *) Remove the index into the bucket-type table from the buckets
3422 structure. This has now been replaced with a pointer to the
3423 bucket_type. Also add some macros to test the bucket-type.
3426 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
3427 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
3428 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
3429 All _VAR_ flavors changes to _DATA to be absolutely clear.
3432 *) Add support for /, //, //servername and //server/sharename
3433 parsing of <Directory> blocks under Win32 and OS2.
3434 [Tim Costello, William Rowe, Brian Harvard]
3436 *) Remove the function pointers from the ap_bucket type. They have been
3437 replaced with a global table. Modules are allowed to register bucket
3438 types and use then use those buckets.
3441 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
3442 once we finish writing the request body to the cgi child process;
3443 otherwise, the client doesn't hit EOF on stdin. Small request bodies
3444 worked without this change (for reasons I don't understand), but large
3445 ones didn't. [Jeff Trawick]
3447 *) Remove file bucket specific information from the ap_bucket type.
3448 This has been moved to a file_bucket specific type that hangs off
3449 the data pointer in the ap_bucket type.
3452 *) Input filtering now has a third argument. This is the amount of data
3453 to read from lower filters. This argument can be -1, 0, or a positive
3454 number. -1 means give me all the data you have, I'll deal with it and
3455 let you know if I need more. 0 means give me one line and one line
3456 only. A positive number means I want no more than this much data.
3458 Currently, only 0 and a positive number are implemented. This allows
3459 us to remove the remaining field from the conn_rec structure, which
3463 *) Big cleanup of the input filtering. The goal is that http_filter
3464 understands two conditions, headers and body. It knows where it is
3465 based on c->remaining. If c->remaining is 0, then we are in headers,
3466 and http_filter returns a line at a time. If it is not 0, then we are
3467 in body, and http_filter returns raw data, but only up to c->remaining
3468 bytes. It can return less, but never more.
3469 [Greg Ames, Ryan Bloom, Jeff Trawick]
3471 *) mod_cgi: Write all of the request body to the child, not just what
3472 the kernel would accept on the first write. [Jeff Trawick]
3474 *) Back out the change that moved the brigade from the core_output_filters
3475 ctx to the conn_rec. Since all requests over a given connection
3476 go through the same core_output_filter, the ctx pointer has the
3480 *) Fix another bug in the send_the_file() read/write loop. A partial
3481 send by apr_send would cause unsent data in the read buffer to
3482 get clobbered. Complete making send_the_file handle partial
3483 writes to the network.
3486 *) Fix a couple of type fixes to allow compilation on AIX again
3487 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
3489 *) Fix bug in send_the_file() which causes offset to be ignored
3490 if there are no headers to send.
3493 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
3494 filter. Useful for supporting Windows 9* with a binary
3495 compiled on Windows NT.
3498 Changes with Apache 2.0a7
3500 *) Reimplement core_output_filter to buffer/save bucket brigades
3501 across multiple calls to the core_filter. The brigade will be
3502 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
3503 thresholds are hit or the EOS bucket is received.
3506 *) Create experimental filter (buffer_filter) that coalesces bytes
3507 into one large buffer before invoking the next filter in the
3508 chain. This filter is particularly useful with the current
3509 implementation of mod_autoindex when it inserted above the
3510 chunk_filter. mod_autoindex generates a lot of brigades that
3511 containing buckets holding just a few bytes each. The
3512 buffer_filter coalesces these buckets into a single large bucket.
3515 *) Add apr_sendfile() support into the core_output_filter.
3518 *) Add apr_sendv() support into the core_output_filter.
3521 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
3522 [Mike Abbott <mja@sgi.com>]
3524 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
3525 make much sense, because Apache uses buckets instead of BUFFs now.
3528 *) send_the_file now falls back to a read/write loop on platforms that
3529 do not have sendfile.
3530 [Ryan Bloom and Brian Havard]
3532 *) Install apachectl correctly, and substitute the proper values so
3533 that it works again. [Ryan Bloom]
3535 *) Better(??) handle platforms that lack sendfile().
3538 *) APR now has UUID generation/formatting/parsing support.
3541 *) Begin the http_filter. This is an input filter that understands
3542 the absolute basic amount required to parse an HTTP Request. The
3543 goal is to be able to split headers from request body before passing
3544 the data back to the other filters.
3547 *) Bring forward from 1.3.13 the config directory implementation
3550 *) install apxs if it is created
3553 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
3554 conversions. [William Rowe]
3556 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
3557 ap_add_output_filter(). [Jeff Trawick]
3559 *) Multiple build and configuration fixes
3562 -add datadir and localstatedir substitutions
3564 -fix logfilename misspelling
3565 -fix evaluation of installation dir variables and
3566 -replace $foobar by $(foobar) to be usefull in the makefile
3570 -add rules for cross-compiling in rules.mk. Okay, rule to check for
3571 $CC_FOR_BUILD is still missing
3572 -use CHECK_TOOL instead of CHECK_PROG for ranlib
3573 -add missing "AR=@AR@" to severaly Makefile.in's
3574 -cache result for "struct rlimit"
3575 -compile all helper programs with native and cross compiler
3576 and use the native version to generate header file
3577 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3579 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
3581 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3583 *) Fix a bug where a client which only sends \n to delimit header
3584 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
3585 message. Start working on ebcdic co-existance with input
3587 [William Rowe, Greg Ames]
3589 *) If mod_so is enabled in the server always create libexec, even
3590 if there are no modules installed in this directory. This is a
3591 requirement for APXS to work correctly.
3594 *) Connection oriented output filters are now stored in the
3595 conn_rec instead of the request_rec. This allows us to add the
3596 output filter in the pre-connection phase instead of the
3597 post_read_request phase, which keeps us from trying to write an
3598 error page before we have a filter to write to the network.
3599 [Ryan Bloom, Jeff Trawick, and Greg Ames]
3601 *) Cleaning up an mmap bucket no longer deletes the mmap. An
3602 mmap can be used across multiple buckets (default_handler with
3603 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
3604 the mmap itself can't be associated with the bucket.
3607 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
3610 *) Radical surgery to improve mod_isapi support under Win32.
3611 Includes a number of newer ServerSupportFunction calls, support
3612 for ReadClient (in order to retrieve POSTs greater than 48KB),
3613 and general bug fixes to more reliably load ISAPI .dll's and
3614 prevent leaking handle resources. Note: There are still
3615 discrepancies between IIS's and Apache's ServerVariables, and
3616 async calls are still not supported. Additional warnings are
3617 logged to facilitate debugging of unsupported ISAPI calls.
3620 *) Add input filtering to Apache. The basic idea for the input
3621 filters is the same as the ideas for output filters. The biggest
3622 difference is that instead of calling ap_pass_brigade, ap_get_brigade
3623 should be called, and the order of execution for the filter itself is
3624 different. When writing an output filter, a brigade is passed in,
3625 and filters operate directly on that brigade, when done, they call
3626 ap_pass_brigade. Input filters are the exact opposite. Because input
3627 is not a push operation, filters first call ap_get_brigade. When this
3628 function returns, the input filter will be left with a valid brigade.
3629 The input filter should then operate on the brigade, and return.
3632 *) Fix building on BSD/OS using its native make. The build system
3633 falls back to the BSD .include directive on that host platform.
3636 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
3637 SHA1 and plaintext password encodings. Make feature tests a
3638 bit more flexible. [William Rowe]
3640 *) Charset translation: mod_charset_lite handles output content
3641 translation in a filter. mod_charset_lite no longer ignores
3642 subrequests. A bunch of cruft related to BUFF's support for
3643 translating request and response bodies was removed.
3646 *) Move the addition of the CORE filter to the post_read_request
3647 hook in http_core.c. This removes the need to add the filter in
3648 multiple places and allows for an SSL module to be added much
3649 simpler. [Ryan Bloom]
3651 *) Fix a security problem that affects certain configurations of
3652 mod_rewrite. If the result of a RewriteRule is a filename that
3653 contains expansion specifiers, especially regexp backreferences
3654 $0..$9 and %0..%9, then it may be possible for an attacker to
3655 access any file on the web server. [Tony Finch]
3657 *) Fix a bug where errors that are detected during early request parsing
3658 don't produce visible HTTP error messages at the browser, because
3659 the core_filter wasn't present. [Greg Ames]
3661 *) Provide apr_socklen_t as a portability aid.
3662 [Victor J. Orlikowski]
3664 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
3665 as well as a comment arg to the add, adduser and update cmds.
3666 update allows the user to clear or preserve pw/groups/comment.
3667 Fixed a bug in dbmmanage that prevented the check option from
3668 parsing a password followed by :group... text. Corrected the
3669 seed calcualation for Win32 systems, and added -lsdbm support.
3672 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
3675 *) Avoid a segfault when parsing .htaccess files. An
3676 uninitialized tree pointer was passed to ap_build_config().
3679 *) Change the way that inet_addr & inet_network are checked for
3680 in APR's configure process to allow BeOS BONE to correctly
3681 find them. With this change BeOS BONE now builds from source
3682 with no problems. [David Reid]
3684 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
3685 the end of the parameters to execve() was stored in the wrong
3686 location, overlaying the storage beyond the newargs[] array and
3687 also passing uninitialized storage to execve(), which would
3688 sometimes fail with EFAULT. [Jeff Trawick]
3690 *) Fix a bug parsing configuration file containers. With a sequence
3691 like this in the config file
3693 <IfModule mod_kilroy.c>
3696 <IfModule mod_lovejoy.c>
3701 the second container would be terminated at the blank line due to
3702 sediment in the buffer from reading the prior </IfModule> and an
3703 error message would be generated for the real </IfModule> for the
3704 second container. Also due to this problem, any two characters
3705 could be used for "</" in the close of a container.
3708 *) ap_add_filter prototype changed to remove the ctx pointer. The
3709 pointer still remains in the filter structure, but it can not be
3710 a part of the ap_add_filter prototype. The reason is that when
3711 the core uses AddFilter to add a filter to the stack it doesn't
3712 know how to allocate the ctx pointer, or even how much memory should
3713 be allocated. The filters will have to be responsible for allocating
3714 the ctx memory when they need it.
3717 *) Add an AddFilter directive. This directive takes a list of filters
3718 that should be activated for the requested resource.
3721 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
3722 some other platforms). [Jeff Trawick]
3724 *) Modify mod_include to be a filter. Currently, it has only been tested
3725 on actual files, but it should work for CGI scripts too.
3728 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
3729 writes. apr_flush() for Unix: handle interrupted writes.
3732 *) NameVirtualHost can now take "*" as an argument instead of
3733 an IP address. This allows you to create a purely name-based
3734 virtual hosting server that does not have any IP addresses in
3735 the configuration file and which ignores the local address
3736 of any connections. PR #5595, PR #4455 [Tony Finch]
3738 *) Fix some compile warnings in mod_mmap_static.c
3739 [Mike Abbott <mja@sgi.com>]
3741 *) Fix chunking problem with CGI scripts. The general problem was that
3742 the CGI modules were adding an EOS bucket and then the core added an
3743 EOS bucket. The chunking filter finalizes the chunked response when it
3744 encounters an EOS bucket. Because two EOS buckets were sent, we
3745 finalized the response twice. The fix is to make sure we only send one
3746 EOS, by utilizing a flag in the request_rec.
3749 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
3750 and Win32. Previously, the first read from an apr_file_t set up via
3751 apr_put_os_file() would return a '\0'. [Jeff Trawick]
3753 *) Mod_cgid now creates a single element bucket brigade, with a pipe
3754 bucket, instead of using BUFF's and ap_r*.
3757 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
3758 [Mike Abbott <mja@sgi.com>]
3760 *) Remove ap_bopenf from buff code. This required modifying the file_cache
3761 code to use APR file's directly instead of going through BUFFs.
3764 *) Fix compile break on some platforms for mod_mime_magic.c
3765 [John K. Sterling <sterling@covalent.net>]
3767 *) Fix merging of AddDefaultCharset directive.
3768 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
3770 *) Minor revamp of the rlimit sections of code. We now test
3771 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
3772 is now "available" even if the platform doesn't support
3773 the rlimit family (it's just a noop though). [Jim Jagielski]
3775 *) Migrate the pre-selection of which MPM to use for specific
3776 platforms to hints.m4, which contains (or should contain)
3777 all platform specific "hints". [Jim Jagielski]
3779 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
3782 *) Add tables with non-string/binary values to APR.
3785 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
3788 *) Update PCRE to version 3.2. [Ryan Bloom]
3790 *) Change the way buckets' destroy functions are called so that
3791 they can be more directly used when changing the type of a
3792 bucket in place. [Tony Finch]
3794 *) Add generic support for reference-counting the resources used by
3795 buckets, and alter the HEAP and MMAP buckets to use it. Change
3796 the way buckets are initialised to support changing the type of
3797 buckets in place, and use it when setting aside TRANSIENT buckets.
3798 Change the implementation of TRANSIENT buckets so that it can be
3799 mostly shared with IMMORTAL buckets, which are now implemented.
3802 Changes with Apache 2.0a6
3804 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
3806 *) Add a chunking filter to Apache. This brings us one step closer
3807 to removing BUFF. [Ryan Bloom]
3809 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
3810 added to the stack is the last filter to be called. [Ryan Bloom]
3812 *) Apache 2.0 has been completely documented using Scandoc. The
3813 docs can be generated by running 'make docs'. [Ryan Bloom]
3815 *) Add filtered I/O to Apache. This is based on bucket brigades,
3816 Currently the buckets still use BUFF under the covers, but that
3817 should change quickly. The only currently written filter is the
3818 core filter which just calls ap_bwrite. [The Apache Group]
3820 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
3821 built with thread support. [Jeff Trawick]
3823 *) Abort configuration if --with-layout was specified and there's
3824 no layout definition file. [Ken Coar]
3826 *) Add support for '--with-port=n' option to configure. [Ken Coar]
3828 *) Add support for extension methods for the Allow response header
3829 field, and an API routine for accessing r->allowed and the
3830 list of extension methods in a unified manner. [Ken Coar]
3832 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
3833 [Rob Simonson <simo@us.ibm.com>]
3835 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
3836 APACHE_XLATE builds. [Jeff Trawick]
3838 *) A configuration file parsing problem was fixed. When the
3839 configuration file started with an IfModule/IfDefine container,
3840 only the last statement in the container would be retained.
3843 Changes with Apache 2.0a5
3845 *) Perchild is serving pages after passing them to different child
3846 processes. There are still a lot of bugs, but this does work. I
3847 have made requests against the same installation of Apache, and had
3848 different servers use different user IDs to serve the responses.
3849 This change moves to using socketpair instead of an AF_UNIX socket.
3852 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
3853 It can't seem to pass between child processes yet, but I think we
3854 are closer now than before. This moves us back to using Unix
3855 Domain Sockets. [Ryan Bloom]
3857 *) libapr functions and types renamed with apr_ prefix.
3858 #include "apr_compat.h" for 1.3.x backwards compat
3861 *) Fix problems with APR sockaddr handling on Win32. It didn't always
3862 return the right information on the local socket address.
3863 [Gregory Nicholls <gnicholls@level8.com>]
3865 *) ap_recv() on Win32: Set bytes-read to 0 on error.
3866 [Gregory Nicholls <gnicholls@level8.com>]
3868 *) Add an option to not detach from the controlling terminal without
3869 going into single process mode. This allows for much easier
3870 debugging of the process startup code. [Ryan Bloom]
3872 *) ab: don't use perror() to report the failure of an APR function.
3875 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
3876 scoreboard on graceful restarts.
3879 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
3880 An invalid ap_proc_t was passed to ap_create_process().
3883 *) Allow modules to register filters. Those filters are still
3884 never called, but this is a step in the right direction.
3885 [Ryan Bloom and Greg Stein]
3887 *) Register the mod_cgid daemon process for cleanup so that it is
3888 killed at termination if it does not die when the parent gets
3889 SIGTERM. This change is to fix occasional problems where the
3890 process stays around. Bugs in similar logic in mod_rewrite and
3891 mod_include were also fixed. [Jeff Trawick]
3893 *) Fix a bug in the time handling. Basically, we were imploding a time
3894 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
3895 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
3896 uses those two fields to adjust the time value. Because of the HTTP
3897 spec, both of those values can be zero'ed out safely. This fixes
3898 the bug correctly. [Ryan Bloom]
3900 *) Fix a couple of place in the Windows code where the wrong error
3901 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
3903 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
3905 *) Added the APR_EOL_STR macro for platform dependent differences in
3906 logfiles and other raw text (such as all APR files). Fixes logfiles
3907 not terminated with cr/lf sequences in Win32. [William Rowe]
3909 *) Move all strings functions in APR to src/lib/apr/strings and create
3910 apr_strings.h for the prototypes. [Ryan Bloom]
3912 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
3913 to repeat the syscall until we stop getting EINTR. I noticed a
3914 related problem at termination (SIGTERM) on FreeBSD when using
3915 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
3916 implementation work properly with child init. Previously, ap_lock()
3917 was essentially a no-op because all children were using different
3918 locks and thus nobody ever blocked. [Jeff Trawick]
3920 *) The htdocs/ tree has been moved out of the CVS source tree into
3921 a separate area for easier development. This has NO EFFECT on
3922 end-users or Apache installations. [Ken Coar]
3924 *) Integrate the mod_dav module for WebDAV protocol handling. This
3925 adds the dav and dav_fs modules, the SDBM library, and additional
3926 XML handling utilities. [Greg Stein]
3928 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
3931 *) Update the lib/expat-lite/ library (bring forward changes from
3932 the Apache 1.3 repository). [Greg Stein]
3934 *) If sizeof(long long) == sizeof(long), then prefer long in APR
3935 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
3937 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
3938 machines where sendfile is detected, but nobody has written ap_sendfile.
3939 [Dave Hill <ddhill@zk3.dec.com>]
3941 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
3943 *) ab would start up more connections than needed, then quit when the
3944 desired number were finished. Also fixed a logic error involving
3945 ab keepalives. [Victor J. Orlikowski]
3947 *) WinNT: Implement non-blocking pipes with timeouts to communicate
3948 with CGIs. Apache 2.0a4 had non-blocking pipes but without
3949 timeouts (i.e, if a timeout was specified, the pipe reverted to
3950 a full blocking pipe). Now the behaviour is more in line with
3951 Unix non-blocking pipes.
3954 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
3955 cache open file handles along with accept socket reuse enables
3956 Apache 2.0 to serve non-keepalive requests for static files at
3957 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
3958 and Apache 2.0 will serve almost 1200 rps on my system).
3961 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
3962 supports two config directives, mmapfile (same behavious as
3963 mod_mmap_static) and cachefile. Use the cachefile directive
3964 to cache open file handles. This directive only works on systems
3965 that have implemented the ap_sendfile API. cachefile works today
3966 on Windows NT, but has not been tested on any flavors of Unix.
3969 *) Cleanup the configuration. With the last few changes the
3970 configuration process automatically:
3971 inherits information about how to build from APR. Allowing
3972 APR to inform Apache that it should or should not use -ldl
3974 Detects which mod_cgi should be used mod_cgi or mod_cgid,
3975 based on the threading model
3977 Apache calls APR's configure process before finishing it's
3978 configuration processing, allowing for more information flow
3983 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
3984 with non-zero argument makes the socket non-blocking. BeOS and
3985 OS/2 already worked this way. [Jeff Trawick]
3987 *) ap_close() now calls ap_flush() for buffered files, so write
3988 operations work a whole lot better on buffered files.
3991 *) Fix error messages issued from MPMs which explain where to change
3992 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
3995 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
3996 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
3997 now the way that the blocking state of a pipe is manipulated.
3998 ap_block_pipe() is gone. [Jeff Trawick]
4000 *) Correct the problem where the only local host name that the IP stack
4001 can discover are 'undotted' private names. If no fully qualified
4002 domain name can be identified, the default ServerName will be set to
4003 the machine's IP address string. A warning is always provided if the
4004 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
4006 *) Repair problems with config file processing which caused segfault
4007 at init when virtual hosts were defined and which caused ServerName to
4008 be ignored when there was no valid DNS setup. [Jeff Trawick]
4010 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
4012 *) Add ap_sendfile implementation for AIX
4013 [Victor J. Orlikowski]
4015 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
4016 apr_network_io.h, and apr_thread_proc.h.
4017 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
4019 *) Bring the allocation and pool debugging code back into a working
4020 state. This will need to be tested as so far it's only been used on
4023 *) Change configuration command setup to be properly typesafe when in
4024 maintainer mode. Note that this requires a compiler that can initialise
4025 unions. [Ben Laurie]
4027 *) Turn on buffering for config file reads. Part of this was to
4028 repair buffered I/O support in Unix and implement buffered
4029 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
4031 *) Win32: Fix problem where UTC offset was not being set correctly
4032 in the access log. Problem reported on news group by Jerry Baker.
4035 *) Fix segfault when reporting this type of syntax error:
4036 "</container> without matching <container> section", where
4037 container is VirtualHost or Directory or whatever.
4040 *) Prevent the source code for CGIs from being revealed when using
4041 mod_vhost_alias and the CGI directory is under the document root
4042 and a user makes a request like http://www.example.com//cgi-bin/cgi
4043 as reported in <news:960999105.344321@ernani.logica.co.uk>
4046 *) Add support for the new Beos NetwOrking Environment (BONE)
4049 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
4050 final input char is incomplete; ap_bwrite_xlate() now handles
4051 incomplete final input chars. [Jeff Trawick]
4053 *) Yet another update to saferead/halfduplex stuff -- need to ensure
4054 that a bhalfduplex call occurs before logging or else DNS and
4055 such can delay the last packet of the response. [Dean Gaudet]
4057 *) Some syscall reduction in APR on unix -- don't seek when setting
4058 up an mmap; and don't fcntl() more than once per socket.
4061 *) When mod_cgid is started as root, the cgi daemon now switches
4062 to the configured User/Group (like other httpd processes)
4063 instead of continuing as root. [Jeff Trawick]
4065 *) The prefork MPM now uses an APR lock for the accept() mutex.
4066 It has not been getting a lock at all recently. httpd -V now
4067 displays APR's selection of the lock mechanism instead of the
4068 symbols previously respected by prefork. [Jeff Trawick]
4070 *) Change the mmap() feature test to check only for existence.
4071 The previous check required features not used by Apache.
4074 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
4075 sometimes mangled. The len parm to accept() was not
4076 initialized, leading sometimes to an endless loop of failed
4077 accept() calls on OS/390 and anywhere else that failed the call
4078 if the len was negative. Use <sys/un.h> for struct sockaddr_un
4079 instead of declaring it ourselves to fix a compilation problem
4080 on Solaris. [Jeff Trawick]
4082 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
4084 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
4086 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
4088 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
4089 initialization if ALLOC_DEBUG is defined; no known symptom
4090 otherwise. [Jeff Trawick]
4092 *) Fix typo in configure script when checking for mod_so. bash
4093 doesn't seem to have a problem but /bin/sh on Solaris does.
4094 Symptom: "./configure: test: unknown operator =="
4097 *) Rebind the Win32 NT and 9x services control into the MPM.
4098 All console, WinNT SCM and Win9x pseudo-service control code is
4099 now wrapped within the WinNT MPM.
4102 *) Make a copy of getenv("PATH") before storing for later use. Some
4103 getenv() implementations use the same storage for successive calls.
4104 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
4106 *) Server Tokens work in 2.0 again. This also propogates the change
4107 to allow just the product name in the server string using
4111 Changes with Apache 2.0a4
4113 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
4114 won't need to call it. [Greg Ames, Jeff Trawick]
4116 *) Move pre_config hook call to between configuration read and config
4117 tree walk. This allows all modules to implement pre_config hooks
4118 and know that they will be called at an appropriate time.
4121 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
4124 *) Add pre-config hooks back to all modules.
4127 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
4128 ContentDigest enabled and we can't/don't mmap the file.
4131 *) We now report the correct line number for syntax errors in config
4132 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
4134 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
4135 related bugs, and changed shmem/locking to use apr API. Shared-mem
4136 is currently disabled, however, because of problems with graceful
4137 restarts. [Ronald Tschalär]
4139 *) Fix corruption of IFS variable in --with-module= handling.
4140 Depending on the user's shell or customization thereof, there
4141 would be errors generating ap_config_auto.h later in the configure
4142 procedure. [Jeff Trawick]
4144 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
4145 isn't used (as in 1.3), except that on Unix it is now logged via
4146 ap_log_rerror() instead of by the child having STDERR_FILENO refer
4147 to the error log. [Greg Ames, Jeff Trawick]
4149 *) Add '-D' argument processing for run time configuration defines.
4152 *) Organize http_main.c as independent code, such that no code or
4153 global data is exported from it. WIN32 will dynamically link it
4154 to the server core, so this will prevent mutual dependency.
4157 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
4158 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
4161 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
4162 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
4164 *) Add mod_charset_lite for configuring character set translation.
4167 *) Add '-n' option to htpasswd to make it print its user:pw record
4168 on stdout rather than having to frob a text file. [Ken Coar]
4170 *) Fix saferead. Basically, we flush the output buffer if a read on the
4174 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
4175 a conversion is single-byte only. [Jeff Trawick]
4177 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
4178 the BeOS 5.0 documentation says that shutdown doesn't work yet.
4181 *) Fix some minor errors where pid was being manipulated as an int
4182 instead of the portable pid_t. [Roy Fielding]
4184 *) Fix some error log prints that were printing the pointer to a
4185 structure rather than the pid within the structure.
4186 [Jeff Trawick, Roy Fielding]
4188 *) ab: Fix a command-line processing bug; track bad headers in
4189 err_response; support reading headers up to 2K.
4190 [Ask Bjoern Hansen <ask@valueclick.com>]
4192 *) Fix ap_resolve_env() so that it handles new function added in a prior
4193 alpha (see "Added the capability to do ${ENVVAR} constructs in the
4194 config file.") as well as the constructs used by mod_rewrite.
4195 [Paul Reder <rederpj@raleigh.ibm.com>]
4197 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
4199 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
4200 APR to perform translation, instead of accessing the hard-coded tables
4201 in 1.3's ebcdic.c. [Jeff Trawick]
4203 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
4206 *) Add the ability to hook into the config file reading phase. Basically
4207 if a directive is specified EXEC_ON_READ, then when that directive is
4208 read from the config file, the assocaited function is executed. This
4209 should only be used for those directives that must muck with HOW the
4210 server INTERPRETS the config. This should not be used for directives
4211 that re-order or replace items in the config tree. Those changes should
4212 be made in the pre-config step.
4215 *) Add mod_example to the build system.
4218 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
4219 byte character sets. [Jeff Trawick]
4221 *) Pick up various EBCDIC fixes from 1.3 (from Martin
4222 Kraemer and Oliver Reh originally according to the change log).
4225 *) Fix a couple of problems in RFC1413 support (controlled by the
4226 IdentityCheck directive). Apache did not build the request string
4227 properly and more importantly Apache would loop forever if the
4228 would-be ident server dropped the connection before sending a
4229 properly terminated response. [Jeff Trawick]
4231 *) apxs works in 2.0.
4234 *) Reliable piped logs work in 2.0.
4237 *) Introduce a hash table implementation into APR to be used for
4238 replacing tables and other random data structures in Apache.
4241 *) Add some more error reporting to htpasswd in the case of problems
4242 generating or accessing the temporary file. Also, pass in a
4243 buffer if the implementation knows how to use it (i.e., if L_tmpnam
4244 is defined). [Ken Coar]
4246 *) Configure creates config.nice now containing your configure
4247 options. Syntax: ./config.nice [--more-options]
4250 *) Fix various return code problems in APR on Win32. For most of
4251 these, APR was returning APR_EEXIST instead of GetLastError()/
4252 WSAGetLastError(). [Jeff Trawick]
4254 *) Make piped logs work again in version 2.0
4257 *) Add VPATH support to UNIX build system of Apache and APR.
4260 *) Fix ap_tokenize_to_argv to respect the const arguments that are
4264 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
4265 Patch submitted to author.
4268 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
4269 /sbin in PATH on FreeBSD (all submitted to rse previously)
4272 *) Fix building Pthread-based MPMs on OpenBSD
4273 [Sascha Schumann] PR#26
4275 *) Fix ap_readdir() problem on systems where d_name[] field in
4276 struct dirent is declared with only one byte. (This problem only
4277 affected multithreaded builds.) This caused a segfault during
4278 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
4279 least). [Jeff Trawick]
4281 *) Fix some make-portability problems on at least Tru64, Irix
4283 [Sascha Schumann] PR#18, PR#39
4285 *) Add ap_sigwait() to support old-style sigwait() on systems
4286 like OS/390 and UnixWare.
4289 *) Add POSIX-thread flags for more platforms.
4292 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
4293 (on Unix, at least) to handle resolver errors. Fix a bug in
4294 the definition of APR_ENOMEM so that ap_strerror() can spit
4295 out the correct error message for it.
4298 Changes with Apache 2.0a3
4300 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
4303 *) API: *HOOK* macros now have an AP_ prefix
4306 *) Win32: Eliminate redundant calls to initialize winsock.
4307 [Tim Costello <timcostello@ozemail.com.au>]
4309 *) Fix bugs initializing ungetchar for pipes.
4310 [Chia-liang Kao <clkao@CirX.ORG>]
4312 *) The ab program in the src/support directory is now portable using
4316 *) Support directory is being compiled when the server is built
4319 *) The configure option --with-program-name has been added to allow
4320 developers to rename the executable at configure time. This also
4321 changes the name of the config files to match the executable's name.
4324 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
4325 containing version numbers. [Martin Pool]
4327 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
4328 Unix; access_log and error_log now created with these perms; non-
4329 Unix is unaffected [Jeff Trawick]
4331 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
4332 Replaced more magic numbers with MD5_DIGESTSIZE.
4333 [William Rowe, Roy Fielding]
4335 *) Win32: Get mod_auth_digest compiling and added to the Windows
4336 build environment. Not tested and I'd be suprised if it
4337 actually works. [Bill Stoddard]
4339 *) Revamp the Win32 make environment. Makefiles have been removed and
4340 Apache.dsw created to bring together all the pieces. Create new file
4341 os/win32/BaseAddr.ref to define module base addresses (to prevent
4342 dll relocation at start-up).
4343 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
4345 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
4346 of the \015, \012, and \015\012 constants with macros.
4349 *) Add ap_xlate_open() et al for translation of text between different
4350 character sets. The initial implementation requires iconv().
4353 *) More FAQs and answers from comp.infosystems.www.servers.unix.
4354 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4356 *) CGI output is being timed out now.
4359 *) Fix the problem with dieing quietly. dupfile now takes a pool which
4360 is used by the new apr file. There is no reason to create a new file
4361 with the same lifetime as the original file.
4364 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
4365 module base addresses. This will help shooting seg faults
4366 in the field. [William Rowe <wrowe@lnd.com>]
4368 *) Update Apache on Windows documentation. Add new document
4369 describing how to compile Apache on Windows.
4370 [William Rowe <wrowe@lnd.com>]
4372 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
4373 microseconds instead of seconds. Some storage leaks and other
4374 minor bugs in related code were fixed. [Jeff Trawick]
4376 *) Win32: First cut at getting mod_isapi working under 2.0
4377 [William Rowe <wrowe@lnd.com>]
4379 *) First stab at getting mod_auth_digest working under 2.0
4380 quick change summary:
4381 - moved the random byte generation (ap_generate_random_bytes) into APR
4382 - now uses ap_time_t
4383 - compiles and runs on linux
4385 [Brian Martin <bmartin@penguincomputing.com>]
4387 *) Win32: Move the space stripping of physical service names
4388 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
4389 unresolved symbol. Add dependency checking to the
4390 CreateService call to ensure TCPIP and AFP (winsock) is started
4392 [William Rowe <wrowe@lnd.com>]
4394 *) Win32: Add code to perform latebinding on functions that may
4395 not exist on all levels of Windows where Apache runs. This
4396 is needed to allow Apache to start-up on Win95/98. All calls
4397 to non portable functions should be protected with
4398 ap_oslevel checks to prevent runtime segfaults.
4399 [William Rowe <wrowe@lnd.com>]
4401 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
4403 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
4405 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
4406 This addresses PR 1623. Still need to address timing out runaway
4407 CGI scripts. [Bill Stoddard]
4409 *) Win32: Make ap_stat Windows 95/98 friendly
4410 [William Rowe <wrowe@lnd.com>]
4412 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
4413 always fail. Need to initialise the dwOSVersionInfoSize member of the
4414 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
4417 The patch also enhances ap_get_oslevel (and the associated enum) to
4418 handle selected service packs for NT4, and adds recognition for
4419 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
4420 we can use ReadFileScatter and WriteFileGather in readwrite.c.
4421 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
4423 *) Get mod_rewrite building and running, and mod_status building for Win NT
4424 [Allan Edwards <ake@raleigh.ibm.com>]
4426 *) Patch to port mod_auth_db to the 2.0 api and also to support
4427 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
4428 2.7.7. It should work with version 1 as well but I haven't tested it.
4429 [Brian Martin <bmartin@penguincomputing.com>]
4431 *) Get APR DSO code working under Windows. Includes cross platform
4433 [Tim.Costello@BTFinancialgroup.com]
4435 *) Fix some of the Windows APR time functions.
4438 *) FAQ changes related to tidying up historical documents on the web site.
4439 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4441 *) Move Windows DSO code into APR.
4444 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
4445 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
4446 at build time. At this point, the server will not compile on Windows because
4447 of the recent DSO commits. Fixing those next.
4448 [Bill Rowe & Bill Stoddard]
4450 *) Added error checking for file I/O APR routines.
4451 [Jon Travis <jtravis@covalent.net>]
4453 *) APR: Don't use the values of resolver error codes for the
4454 corresponding APR error codes. On Unix and Win32, return the
4455 proper APR error code after a resolver error. [Jeff Trawick]
4457 Changes with Apache 2.0a2
4459 *) Renamed the executable back to httpd on all platforms other
4463 *) Allow BeOS to survive restarts, log properly and a few
4464 small things it had problems with due to the way it setup
4465 users and groups. [David Reid]
4467 *) Get mod_rewrite working with APR locks
4468 [Paul Reder <rederpj@raleigh.ibm.com>]
4470 *) Actually remove the sempahore when the lock cleanup routine
4471 is called on BeOS. [David Reid]
4473 *) Clear hook registrations between reads of the config file.
4474 When DSOs are unloaded and re-loaded the old hook pointers may
4475 no longer be valid. This fix eliminates potential segfaults.
4476 [Allan Edwards <ake@raleigh.ibm.com>]
4478 *) Fix a problem with Sigfunc not being defined or bypassed
4479 if sigaction() wasn't found. [Jim Jagielski]
4481 *) Fix the locking mechanism on BSD variants. They now use fcntl
4482 locks. This allows the server to start and serve pages.
4485 *) First cut at getting the Win32 installer to work
4486 [William Rowe <wrowe@lnd.com>]
4488 *) Get htpasswd compiling under Windows
4489 [William Rowe <wrowe@lnd.com>]
4491 *) Change the log message for a bind() failure to show the
4492 interface and port number. [Jeff Trawick]
4494 *) Import the documentation from 1.3.12 and bring parts of it
4495 up-to-date with respect to the changes that have occurred
4499 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
4500 now logged correctly on BeOS.
4503 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
4504 Makefile.win includes the same user interface as the old
4506 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
4508 *) Win32 exec now uses COMSPEC environment string for command
4509 shell path resolution.
4510 [William Rowe <wrowe@lnd.com>] PR#3715
4512 *) Win32: ap_connect() was not returning correct error condition
4514 [Allen Prescott <allen@clanprescott.com>]
4516 *) Win32: ap_open() was broken on Win9x because an NT-specific
4517 flag was passed to CreateFile. ap_puts() added an unnecessary
4519 [Jeff Trawick <trawick@us.ibm.com>]
4521 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
4522 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
4523 confusing ee/et name and made all extensions language/dialect
4524 rather than country reflecting. Changed example files to
4525 explicit reflect the ISO charset and added a few common
4526 ones to the example config [dirkx]
4528 *) Extend external module capability. To use this, you call
4529 configure with --with-module=path/to/mod1,path/to/mod2,etc.
4532 *) Backported the various "default charset" fixes from 1.3.12,
4533 including the AddDefaultCharset directive. [Jim Jagielski]
4535 *) Added the capability to do ${ENVVAR} constructs in the
4536 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
4537 it does this on a line by line basis; i.e. if the envvar
4538 expands to something with spaces you have to protect it
4539 by adding quotes around it (Unless of course you expect it
4540 to contains more than one argument. Alternatively you
4541 can compile it on a per token basis; which is what people
4542 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
4543 hampers fancier hacks.
4544 [Dirk-Willem van Gulik]
4546 *) Changed the 'ErrorDocument' syntax in that it NO longer
4547 supports the asymetric
4549 ErrorDocument 301 "Some message
4551 Note the opening " quote, without a closing quote. It now
4552 has either the following syntaxes
4554 ErrorDocument XXX /local/uri
4555 ErrorDocument XXX http://valid/url
4556 ErrorDocument XXX "Some Message"
4558 The recognition heuristic is: if it has a space it
4559 is a message. If it has no spaces and starts with a /
4560 or is a valid URL then treat it that way. Otherwise it
4561 is assumed to be a message.
4563 This breaks backward compatibility but makes live a hell
4564 of a lot easier for GUI's and config file parsers.
4565 [Dirk-Willem van Gulik]
4567 *) Changed 'CacheNegotiatedDocs' from its present/not-present
4568 syntax into a 'on' or 'off' syntax. As it currently is the
4569 only non nesting token which uses NO_ARGS and thus is an
4570 absolute pain for any config interface automation. This
4571 breaks backward compatibility. [Dirk-Willem van Gulik]
4573 *) Add ability to add external modules to the build process. This is
4574 done with --with-module=/path/to/module. Modules can only be added
4575 as static modules at this point.
4578 Changes with Apache 2.0a1
4580 *) Fix FreeBSD 3.3 core dump.
4581 Basically, ap_initialize() needs to get called before
4582 create_process(), since create_process() passes op_on structure
4583 to semop() to get a lock, but op_on isn't initialized until
4584 ap_initialize() calls setup_lock(). Here is a slight
4585 rearrangement to main() which calls ap_initialize() earlier...
4586 [Jeff Trawick <trawick@us.ibm.com>]
4588 *) Enable Apache to use sendfile/TransmitFile API
4589 [Bill Stoddard, David Reid, Paul Reder]
4591 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
4595 *) Make file I/O and network I/O writev/sendv APIs consistent.
4596 Eliminate use of ap_iovec_t and use Posix struct iovec.
4597 Use seperate variable on ap_writev to set the number of iovecs
4598 passed in and number of bytes written.
4601 *) Adapt file iol to use APR functions. Replaced ap_open_file()
4602 with ap_create_file_iol(). ap_create_file_iol() requires that
4603 the file be opened prior to the call using ap_open().
4606 *) Port mod_include and mod_cgi to 2.0
4607 [Paul Reder, Bill Stoddard]
4609 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
4610 bytes_read/bytes_written is always valid (never -1). Plus
4611 some fixes to buff.c to correct problems introduced by the
4612 errno => ap_status_t changes a while back. Plus a fix to
4613 chunked encoding introduced right at the beginning of 2.0.
4616 *) Revamped UNIX build system to use autoconf and libtool.
4617 [Manoj Kasichainula, Sascha Schumann]
4619 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
4621 *) More rigorous checking of Host: headers to fix security problems
4622 with mass name-based virtual hosting (whether using mod_rewrite
4623 or mod_vhost_alias).
4624 [Ben Hyde, Tony Finch]
4626 *) Add back support for UseCanonicalName in <Directory> containers.
4627 [Manoj Kasichainula]
4629 *) Added APLOG_STARTUP log type. This allows us to write an error
4630 message without any of the date and time information. As a part
4631 of this change, I also removed all of the calls to fprintf(stderr
4632 and replaced them with calls to ap_log_error using APLOG_STARTUP
4633 writing to stderr is no longer portable, because we don't direct
4634 stderr to the error log on all platforms.
4637 *) Convert error logging functions to take errno as an argument.
4638 This makes our error logs more portable, because some Windows API's
4639 don't set errno. This change allows us to still output a valid
4640 message on all of our platforms.
4643 *) mod_mime_magic runs in 2.0-dev now.
4644 [Paul Reder <rederpj@raleigh.ibm.com>]
4646 *) sendfile has been added to APR.
4647 [John Zedlewski <zedlwski@Princeton.EDU>]
4649 *) buff.c has been converted to no longer use errno.
4650 [Manoj Kasichainula]
4652 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
4653 interface adaption to APR functions did it. [Martin Kraemer]
4655 *) Support DSOs properly on 32-bit HP-UX 11.0
4656 [Dilip Khandekar <dilip@cup.hp.com>]
4658 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
4659 [Ralf S. Engelschall]
4661 *) Cleaned APR build environment integration and bootstrap APR
4662 automatically for developers from src/Configure.
4663 [Ralf S. Engelschall]
4665 *) Fixed building of src/support/htpasswd.c
4666 [Ralf S. Engelschall]
4668 *) When generating the Location: header, mod_speling forgot
4669 to escape the spelling-fixed uri. (Forw-Port from 1.3)
4672 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
4674 *) Change all pools to APR contexts. This is the first step to
4675 incorporating APR into Apache. [Ryan Bloom]
4677 *) Move "handler not found" warning message to below the check
4678 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
4679 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
4681 *) Support line-continuation feature in config.option file and
4682 allow the loading of multiple option sections at once via
4683 ``--with-option=<section1>,<section2>,...''
4684 [Ralf S. Engelschall]
4686 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
4688 Changes with Apache MPM
4690 *) Use asynchronous AcceptEx() and a completion port to accept and
4691 dispatch connections to threads in Windows NT/2000.
4694 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
4697 *) Implement the APACI --with-option facility
4698 (per default used the config.option file).
4699 [Ralf S. Engelschall]
4701 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
4703 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
4704 Replace pre_connection module call with a register_hook call and
4705 implement pre_connection as a hook. The intent is that these hooks will
4706 be extended to allow Apache to be multi-protocol, and also to allow the
4707 calling order to be specified on a per-hook/per-module basis.
4710 *) Implement mpm_* methods as "modules". Each method gets its own
4711 subdir in src/modules (eg: src/modules/prefork). Selection
4712 of method uses Rule MPM_METHOD. [Jim Jagielski]
4714 *) Port the hybrid server from the apache-apr repository as
4715 mpm_mpmt_pthread. [Manoj Kasichainula]
4717 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
4718 amongst the unix MPMs.
4720 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
4721 signal handling for the new world order. [Dean Gaudet]
4723 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
4724 of alloc.c for now. [Dean Gaudet]
4726 *) Handle partial large writes correctly. [Ben Laurie]
4728 *) Eliminate conn_rec's pointer to server. All it knows is the base server
4729 based on IP/port. [Ben Laurie]
4731 *) Port a bunch of modules to the new module structure.
4732 ["Michael H. Voase" <mvoase@midcoast.com.au>]
4734 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
4736 *) Basic restructuring to introduce the MPM concept; includes various
4737 changes to the module API... better described by
4738 docs/initial_blurb.txt. [Dean Gaudet]
4740 Changes with Apache pthreads
4742 *) New buff option added: BO_TIMEOUT. It describes the timeout for
4743 buff operations (generally over a network).
4744 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
4746 *) Created http_accept abstraction. Added 4 new functions (not exported):
4747 init_accept(), begin_accepting_requests(), get_request(),
4748 stop_accepting_requests() [Bill Stoddard]
4750 *) Fix to ap_rprintf call that allows mod_info to work properly.
4751 [James Morris <jmorris@intercode.com.au>]
4753 *) user and ap_auth_type fields were moved from connection_rec to
4754 request_rec. [Ryan Bloom]
4756 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
4757 needed in a threaded server.
4759 *) Initial pthread implementation from from Dean's apache-nspr code.
4760 [Bill Stoddard, Ryan Bloom]
4763 Changes with Apache 1.3.9
4765 *) Remove bogus error message when a redirect doesn't set Location.
4766 Instead, use an empty string to avoid coredump if the error message
4767 was supposed to include a location. [Roy Fielding]
4769 *) Don't allow configure to include mod_auth_digest unless it is
4770 explicitly requested, even if the user asked for all modules.
4773 *) Translate module names to dll names for OS/2 so that they are no more
4774 than 8 characters long and have an extension of "dll" instead of "so".
4777 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
4778 Fix test-compile check to check for randbyte instead of trand32.
4779 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
4780 and tweak to make Amaya happier. [Ronald Tschalär]
4782 *) Ensure that the installed expat include files are world readable,
4783 just like the other header files. [Martin Kraemer]
4785 *) Fixed generated AddModule adjustments in APACI's `configure' script
4786 in order to allow (new) modules like mod_vhost_alias to be handled
4787 correctly (which was touched by the adjustments for mod_alias).
4788 [Ralf S. Engelschall]
4790 *) For binary builds, add -R flag to apachectl to work around the lack of
4791 an absolute path to the ./libexec directory where the libhttp.ep file
4792 is needed for SHARED_CORE architectures. [Randy Terbush]
4794 *) WIN32: Create the CGI script process as DETACHED. This may solve the
4795 problem observed by some Win95/98 users where they get CGI script
4796 output sent to the console. [Bill Stoddard]
4798 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
4799 routines are now called ap_base64* and are 'plain' (i.e., no
4800 pool access or anything clever). Inside util.c the routines acting
4801 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
4802 The oddly named ap_uuencode(), ap_uudecode() are kept around for
4803 now but deprecated. [dirkx]
4805 *) Clean up the base64 and SHA1 additions and make sure they are
4806 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
4807 files. [Roy Fielding]
4809 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
4810 checking. Allow compiling on VS 6.0. [Randy Terbush]
4812 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
4814 *) Use TestCompile to search for the truerand library (rather than blindly
4815 assuming its existence). If it is not found, complain (but do not
4816 exit - yet). [Martin Kraemer]
4818 *) We forgot to add the new exported function names to
4819 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
4821 *) Add description of -T command-line option to usage().
4822 [Ralf S. Engelschall]
4824 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
4825 searched only AFTER libap has been searched, because libap needs
4826 some symbols from libos. [Martin Kraemer]
4828 *) Fix conflict with original mod_digest related to the symbol of the
4829 module dispatch list (which has to be unique for DSO and follow the
4830 usual conventions for the installation procedure).
4831 [Ralf S. Engelschall]
4833 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
4834 for other platforms as well. [Martin Kraemer]
4836 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
4837 types by AP_LONG and replace reference to renamed variable 'ubuf'
4838 by 'buffer'. [Martin Kraemer]
4840 Changes with Apache 1.3.8 [not released]
4842 *) Flush the output buffer immediately after sending an error or redirect
4843 response, since the result may be needed by the client to abort a
4844 long data transfer or restart a series of pipelined requests.
4845 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
4847 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
4848 [Ian Turner <iant@sequent.com>] PR#4735
4850 *) Local struct mmap in http_core.c conflicted with system structure
4851 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
4853 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
4854 [Ronald Tschalär <ronald@innovation.ch>]
4856 *) Fix a memory leak where the module counts were getting messed
4857 up across restarts. [David Harris <dharris@drh.net>]
4859 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
4860 properly in mod_access.
4861 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
4863 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
4864 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
4866 *) PORT: Support for compaq/tandem/com.
4867 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
4869 *) Added SHA1 password encryption support to easy migration from
4870 Netscape servers. See support/SHA1 for more information.
4871 Caused the separation of ap_md5.c into md5, sha1 and a general
4872 ap_checkpass.c with just a validate_passwd routine. Added a
4873 couple of flags to support/htpasswd. Some reuse of the to64()
4874 function; hence renamed to ap_to64().
4875 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
4877 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
4878 with ASCII/EBCDIC conversions in "ident" query.
4879 [David McCreedy <McCreedy@us.ibm.com>]
4881 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
4882 Change "Power Macintosh" to Power* so if uname prints "Power Book"
4883 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
4885 *) Fix SIGSEGV on some systems because the Vary fix below included
4886 a call to table_do with a variable argument list that was not
4887 NULL terminated. Replaced with better implementation. [Roy Fielding]
4889 Changes with Apache 1.3.7 [not released]
4891 *) The "Vary" response header field is now sanitised right before
4892 the header is sent back to the client. Multiple "Vary" fields
4893 are combined, and duplicate tokens (e.g., "Vary: host, host" or
4894 "Vary: host, negotiate, host, accept-language") are reduced to
4895 single instances. This is a better solution than the force-no-vary
4896 one (which is still valid for clients that can't cope with Vary
4897 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
4899 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
4901 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
4902 least on Linux and FreeBSD for now.
4905 *) Win32: More apache -k restart work. Restarts are now honored
4906 immediately and connections in the listen queue are -not- lost.
4907 This is made possible by the use of the WSADuplicateSocket()
4908 call. The listeners are opened in the parent, duplicated, then
4909 the duplicates are passed to the child. The original listen sockets
4910 are not closed by the parent across a restart, thus the listen queue
4912 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4914 *) Fix handling of case when a client has sent "Expect: 100-continue"
4915 and we are going to respond with an error, but get stuck waiting to
4916 discard the body in the pointless hope of preserving the connection.
4917 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
4919 *) Fix 'configure' to work correctly with SysV-based versions of
4920 'tr' (consistent with Configure's use as well). [Jim Jagielski]
4922 *) apxs: Add "-S var=val" option which allows for override of CFG_*
4923 built-in values. Add "-e" option which works like -i but doesn't
4924 install the DSO; useful for editing httpd.conf with apxs. Fix
4925 editing code so that multiple invocations of apxs -a will not
4926 create duplicate LoadModule/AddModule entries; apxs can now be
4927 used to re- enable/disable a module. [Wilfredo Sanchez]
4929 *) Win32: Update the server to use Winsock 2. Specifically, link with
4930 ws2_32.lib rather than wsock32.lib. This gives us access to
4931 WSADuplcateSocket() in addition to some other enhanced comm APIs.
4932 Win 95 users may need to update their TCP/IP stack to pick up
4933 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
4934 [Bill Stoddard stoddard@raleigh.ibm.com]
4936 *) Win32: Redirect CGI script stderr (script debug info) into the
4937 error.log when CGI scripts fail. This makes Apache on Win32
4938 behave more like Unix.
4939 [Bill Stoddard stoddard@raleigh.ibm.com]
4941 *) Fixed `httpd' usage display: -D was missing.
4942 [Ralf S. Engelschall] PR#4614
4944 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
4945 [Ralf S. Engelschall] PR#4561, PR#4562
4947 *) OS/2: Fix problem with accept lock semaphores where server would die with
4948 "OS2SEM: Error 105 getting accept lock. Exiting!"
4949 [Brian Havard] PR#4505
4951 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
4952 [Randy Terbush <randy@covalent.net>]
4954 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
4955 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
4957 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
4958 command potentially _is_ GCC. [Ralf S. Engelschall]
4960 *) Fix apxs build issues on AIX
4961 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
4963 *) DocumentRoot Checking: Under previous versions, when Apache
4964 first started up, it used to do a stat of each DocumentRoot to
4965 see if it existed and was a directory. If not, then an error
4966 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
4967 does not exist, you will get error messages in error_log. If
4968 the '-t' command line option is used (to check the configuration)
4969 the check of DocumentRoot IS performed. An additional command
4970 line option, '-T', has been added if you want to avoid the
4971 DocumentRoot check even when checking the configuration.
4974 *) Win32: The query switch "apache -S" didn't exit after showing the
4975 vhost settings. That was inconsistent with the other query functions.
4976 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
4978 *) Win32: Changed behaviour of apache -k restart.
4979 Previously, the server would drain all connections in the stack's
4980 listen queue before honoring the restart. On a busy server, this
4981 could take hours. Now, a restart is honored almost immediately.
4982 All connections in Apache's queues are handled but connections in
4983 the stack's listen queue are discarded. Restart triggered by
4984 MaxRequestPerChild is unchanged.
4985 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4987 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
4988 the accept loop. Good for a 5% performance boost. Cleaned up
4989 parent/child process management code.
4990 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4992 *) Added ceiling on file size for memory mapped files.
4993 [John Giannandrea <jg@meer.net>] PR#4122
4995 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
4996 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
4997 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
4999 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
5000 use this at least for Expat. [Ralf S. Engelschall]
5002 *) Allow .module files to specify libraries with Lib:.
5005 *) Allow SetEnvIf[NoCase] to test environment variables as well
5006 as header fields and request attributes. [Ken Coar]
5008 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
5009 content-types are "text/html;parameters". PR#4524 [Ken Coar]
5011 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
5012 never accepted into any standard, and it opens up certain DoS
5013 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
5015 *) TestCompile updated. We can now run programs and output the
5016 results during the Configure process. [ Jim Jagielski]
5018 *) The source is now quad (long long) aware as needed. Specifically,
5019 the Configure process determines the correct size of off_t and
5020 *void. When the OS/platform/compiler supports quads, ap_snprintf()
5021 provides for the 'q' format qualifier (if quads are not available,
5022 'q' is silently "demoted" to long). [Jim Jagielski]
5024 *) When the username or password fed to htpasswd is too long, include the
5025 size limit in the error message. Also report illegal characters
5026 (currently only ':') in the username. Add the size restrictions
5027 to the man page. [Ken Coar]
5029 *) Fixed the configure --without-support option so it doesn't result in
5030 an infinite loop. [Marc Slemko]
5032 *) Piped error logs could cause a segfault if an error occured
5033 during configuration after a restart.
5034 [Aidan Cully <aidan@panix.com>] PR#4456
5036 *) If a "Location" field was stored in r->err_headers_out rather
5037 than r->headers_out, redirect processing wouldn't find it and
5038 the server would core dump on ap_escape_html(NULL). Check both
5039 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
5040 if Location isn't set. [Doug MacEachern, Ken Coar]
5042 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
5043 of the Expat 1.0.2 distribution. [Greg Stein]
5045 *) Replace regexec() calls with calls to a new API stub function
5046 ap_regexec(). This solves problems with DSO modules which use the regex
5047 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
5049 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
5050 environment variables can be set according to the protocol version
5051 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
5053 *) Add DSO support for OpenStep (Mach 4.2) platform.
5054 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
5056 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
5057 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
5059 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
5060 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
5062 *) Better DSO flags recognition on NetBSD platforms using ELF.
5063 [Todd Vierling <tv@pobox.com>] PR#4310
5065 *) Always log months in english format for %t in mod_log_config.
5066 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
5068 *) Support for server-parsed and multiview-determined ReadmeName and
5069 HeaderName files in mod_autoindex. Removed the restriction on
5070 "/"s in ReadmeName and HeaderName directives since the *sub_req*
5071 routines will deal with the access issues. (It's now possible to
5072 have {site|group|project|customer|...} wide readmes and headers.)
5073 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
5076 *) When stat() fails, don't assume anything about the contents of
5077 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
5079 *) It's OK for a semop to return EINTR, just loop around and try
5080 again. [Dean Gaudet]
5082 *) Fix configuration engine re-entrant hangups, which solve a
5083 handful of problems seen with mod_perl <Perl> configuration sections
5084 [Salvador Ortiz Garcia <sog@msg.com.mx>]
5086 *) Mac OS and Mac OS X Server now use the appropriate custom layout
5087 by default when building with APACI; allow for platform-specific
5088 variable defaults in configure. [Wilfredo Sanchez]
5090 *) Do setgid() before initgroups() in http_main; some platforms
5091 zap the grouplist when setgid() is called. This was fixed in
5092 suexec earlier, but the main httpd code missed the change.
5093 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
5095 *) Add recognition of .tgz as a gzipped tarchive.
5096 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
5098 *) mod_include's fsize/flastmod should allow only relative paths, just
5099 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
5101 *) OS/2: Add support for building loadable modules using DLLs.
5104 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
5107 *) Fix minor but annoying bug with the test for Configuration.tmpl
5108 being newer than Configuration so that it is less likely to fail
5109 when using APACI and shadow sources. [Wilfredo Sanchez]
5111 *) PORT: Add initial support for Mac OS (versions 10.0 and
5112 greater). Use Mac OS X Server layout for now. Clean up dyld code
5113 in unix/os.c, and don't install the dyld error handlers, which
5114 are no longer needed in Mac OS. [Wilfredo Sanchez]
5116 *) Rename Rhapsody layout to "Mac OS X Server". Change install
5117 locations to appropriate ones for user-built (as opposed to
5118 system) installs. [Wilfredo Sanchez]
5120 *) Modify mod_autoindex's handling of AddDescription so that the
5121 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
5123 *) Add functionality to the install-bindist.sh script created by
5124 binbuild.sh to use tar when copying distribution files to the
5125 serverroot. This allows upgrading an existing installation
5126 without nesting the new distribution in the old.
5128 install-bindist.sh now detects the local perl5 path to install
5129 apxs and dbmmanage with proper path to perl interpreter.
5131 Add an install-binsupport target which copies the source files
5132 for apxs and dbmmanage to bindist to allow these scripts to
5133 be properly installed relative to the destination serverroot.

5162 to happen for anyother values of DirectoryIndex that will map back

5250 htpasswd utility was limiting passwords to only 8 characters.
5253 *) EBCDIC platforms: David submitted patches for two bugs in the
5254 MD5 digest port for EBCDIC machines:
5255 a) the htdigest utility overwrote the old contents of the digest file
5256 b) the Content-MD5 header value (ContentDigest directive) was wrong
5257 when the returned file was not converted from EBCDIC, but was a
5258 binary (e.g., image file) in the first place.
5259 [David McCreedy <mccreedy@us.ibm.com>]
5261 *) support/htpasswd now permits the password to be specified on the

5266 *) Win32: Win32 multiple services patch. Added capability to install and
5267 run multiple copies of apache as individual services.

5297 mismatches were causing compilation problems with gcc -pedantic and
5298 in the TPF cross-compilation. [Ken Coar]
5300 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
5301 a roughly 5 fold speed up. [Brian Havard]
5303 *) proxy ftp: instead of using the hardwired string "text/plain" as
5304 a fallback type for files served by the ftp proxy, use the
5305 ap_default_type() function to determine the configured type.
5306 This allows for special configurations like
5307 <Directory proxy:ftp://some.host>
5308 DefaultType gargle/blurb
5310 Additionally, add the Content-Encoding: header to FTP proxy replies
5311 when the encoding is defined (by the AddEncoding directive).
5312 Because it was missing, it was almost impossible to browse compressed
5313 files using the FTP proxy (works now perfectly in Communicator).
5314 The ftp proxy now also returns the Date: and Server: header lines (if not
5315 much else... This code is "somewhat" broken) like normal requests do.
5318 *) Be more smart in APACI's configure script when determining the UID/GID
5319 for User/Group directives and use the determined UID/GID to initialize
5320 the permissions on the proxycachedir.
5321 [Dirk-Willem van Gulik, Ralf S. Engelschall]
5323 *) Changed the forking-prior-to-cleanup in the proxy module to first

5325 the number of fork()s from one/request to just the odd one an hour.
5326 [Dirk-Willem van Gulik]

5355 *) M_INVALID needed a value within the scope of METHODS so that unknown
5356 methods can be access controlled. [Roy Fielding] PR#3821
5358 *) Added PassAllEnv; makes server's entire environment available
5359 to CGIs and SSIs executed within directive's scope. [Ken Coar]
5361 *) ap_uuencode() always added two trailing '='s and encoding of
5362 8 bit characters on a machine with signed char may produced
5363 incorrect results. Additionally ap_uuencode() should now
5364 work correctly on EBCDIC platforms.
5365 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
5367 *) WIN32: Binary installer now runs the configuration DLL before
5368 the reboot prompt (which is only given if MSVCRT.DLL system
5369 DLL is new or updated). This should avoid the configuration
5370 directory being empty after installation. [Paul Sutton]

5394 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
5395 for 8-bit safeness. [Dean Gaudet]
5397 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
5398 because SPARCs have a small machine-specific maximum size for the Global
5399 Offset Table which is often exceeded when compiling one of the larger
5400 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
5402 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

5423 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
5424 possible buffer overflows. [Ralf S. Engelschall]
5426 *) Remove no longer used non-API function ap_single_module_init().
5427 [Ralf S. Engelschall]
5429 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
5432 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
5433 to make platform installations easier. [Wilfredo Sanchez]
5435 *) In configure, do not append the target name to the directory path if
5436 the path already contains "apache". [Ralf S. Engelschall]
5438 *) SIGPIPE is now ignored by the server core. The request write routines
5439 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
5440 correctly check for output errors and mark the connection as aborted.
5441 Replaced many direct (unchecked) calls to ap_b* routines with the
5442 analogous ap_r* calls. [Roy Fielding]
5444 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
5445 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
5446 Furthermore map lookups for non-existent keys are now cached as well.
5447 Additionally "txt" maps are now parsed with simple string functions
5448 instead of using ap_pregcomp(). As a side effect a bug that prevented
5449 the usage of keys containing the "," character was fixed.
5450 The changes drastically improve the performance when large rewrite maps
5452 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
5454 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
5455 other than GET, and const'd the definition of method in request_rec.
5458 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
5460 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
5461 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
5463 *) Add %V to mod_log_config, this logs the hostname according to the
5464 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
5465 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
5467 *) Add support for \n and \t to mod_log_config, can be used to produce
5468 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
5470 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
5472 *) Added informative error messages for failed munmap() and fseek() calls
5473 in http_core.c. [John Bley, Roy Fielding]
5475 *) Added some informative error messages for some failed malloc()
5476 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
5478 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
5479 is removed. This allows <Directory proxy:*> directives to work and
5480 prevents invalid requests from killing the process.
5481 [Brian Havard <brianh@kheldar.apana.org.au>]
5483 *) Reorganised FAQ document.
5484 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
5486 *) src/support/: The ApacheBench benchmark program was overhauled by
5487 David N. Welton: you can now have it generate an HTML TABLE, presumably
5488 for integration into other HTML sources. David updated the ab man page
5489 as well and added some missing descriptions. Thanks!
5490 [David N. Welton <davidw@prosa.it>]
5492 *) Win32: The filename validity checker now allows filenames containing
5493 characters in the range 0x80 to 0xff (for example accented characters).
5494 [Paul Sutton] PR#3890
5496 *) Added conditional logging based upon environment variables to
5497 mod_log_config. mod_log_referer and mod_log_agent
5498 are now deprecated. [Ken Coar]
5500 *) Allow apache acting as a proxy server to relay the real
5501 reason of a failure to a client rather than the "internal
5502 server error" it does currently. The general exposure mechanism
5503 can be triggered by any module by setting the "verbose-error-to"
5504 note to "*"; this allows more than just proxy errors to be exposed.
5505 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
5507 *) Moved man pages for ab and apachectrl to section 8.
5508 [Wilfredo Sanchez, Roy Fielding]
5510 *) Added -S option to install.sh so that options can be passed to
5511 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
5513 *) Tweak modules Makefile generated by Configure so that it handles
5514 the test case of no modules being selected. [chaz@reliant.com]
5516 *) Added a <LimitExcept method ...> sectioning directive that allows
5517 the user to assign authentication control to any HTTP method that
5518 is *not* given in the argument list; i.e., the logical negation
5519 of the <Limit> directive. This is particularly useful for controlling
5520 access on methods unknown to the Apache core, but perhaps known by
5521 some module or CGI script. [Roy Fielding, Tony Finch]
5523 *) Prevent apachectl from complaining if the PIDFILE exists but
5524 does not contain a process id, as might occur if the server is
5525 being rapidly restarted. [Wilfredo Sanchez]
5527 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
5529 *) Entity tag comparisons for If-Match and If-None-Match were not being
5530 performed correctly -- weak tags might cause false positives. Also,
5531 strong comparison wasn't properly enforced in all cases.
5532 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
5534 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
5537 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
5538 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
5540 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
5541 to util.c for parsing an HTTP header field value to extract the next
5542 list item, taking into account the possible presence of nested comments,
5543 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
5544 insignificant whitespace and lowercases non-quoted tokens.
5545 [Roy Fielding] PR#2065
5547 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
5548 code different from 500. This allows the proxy to, e.g., return
5549 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
5551 *) Fix ordering of language variants for the case where the traditional
5552 negotiation algorithm is being used with multiple language variants
5553 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
5555 *) Do not round the TCN quality calculation to 5 decimal places,
5556 unlike RFC 2296, because the calculation might need 12 decimal places
5557 to get the right result. [Roy Fielding]
5559 *) Remove unused code to disable transparent negotiation when
5560 negotiating on encoding only, as we now handle encoding too
5561 (though this is nonstandard for TCN), remove charset=ISO-8859-1
5562 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
5563 some debugging statements within mod_negotiation. [Koen Holtman]
5565 *) Fixed a rare memory corruption possibility in mod_dir if the index
5566 file is negotiable and no acceptable variant can be found.
5567 [Dean Gaudet, Roy Fielding, Martin Kraemer]
5569 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
5570 searching the Win32 registry for script interpreters.
5573 *) Win32: The compiled-in default filename for the error log is now
5574 error.log, which matches the default in the distributed httpd.conf.
5577 *) Win32: Any error messages from -i or -u command line options are now
5578 displayed on the console output rather than sent to the error log.
5579 Also the "Running Apache..." message is not output unless Apache is
5580 going to serve requests. [Paul Sutton]
5582 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
5583 and use a private significator ('$apr1$') to mark passwords as
5584 being smashed with our own algorithm. Also abstract the password
5585 checking into a new ap_validate_password() routine. [Ken Coar]
5587 *) Win32: The filename validity checker now allows "COM" but refuses
5588 access to "COM1" through "COM4". This allows filenames such
5589 as "com.name" to be served. [Paul Sutton] PR#3769.
5591 *) BS2000: Adapt to the new ufork() system call interface which will
5592 make subtasking easier on the OSD/POSIX mainframe environment.
5595 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
5596 ap_compat.h. [David White <david@persimmon.com>] PR#3725
5598 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
5599 use `.db' instead of `.pag' not only for FreeBSD, but also when
5600 the NDBM library looks like Berkeley-DB based.
5601 [Ralf S. Engelschall] PR#3773

5604 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
5606 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
5608 *) SECURITY: Avoid some buffer overflow problems when escaping
5609 quoted strings. (This overflow was on the heap and we believe
5610 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
5612 *) Let src/Configure be aware of CFLAGS options starting with plus
5613 signs as it's the case for the HP/UX compiler.

5616 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
5617 and check to see if the tar we wind up with supports '-h'.
5618 [Jim Jagielski] PR#3671
5620 *) A consistent and conservative style for all shell scripts has been
5621 implemented. Basically, all shell string tests use the traditional
5622 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
5623 to protect against bare null variable strings (ie: wrapping both
5624 sides with double quotes and prepending 'x'). 'x' was chosen
5625 because it's more universal and hopefully easier for old shell
5626 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
5629 *) The status module now prints out both the main server generation as
5630 well as the generation of each process. Also, the vhost info is
5631 printed with '?notable'. [Jim Jagielski]
5633 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
5634 and this makes its functions available to things in src/support.
5637 Changes with Apache 1.3.4
5639 *) Renamed macros status_drops_connection to ap_status_drops_connection
5640 and vestigial scan_script_header to ap_scan_script_header_err,
5641 mostly for aesthetic reasons. [Roy Fielding]
5643 *) The query switch "httpd -S" didn't exit after showing the
5644 vhost settings. That was inconsistent with the other query functions.
5647 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
5648 filename to the end of the STANDARD_MODULE_STUFF. Its
5649 presence at the beginning prevented reporting of the filename
5650 for modules compiled before 1 January 1999. [Ken Coar]
5652 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
5653 to detect and prevent access to special DOS device file names.
5654 [Paul Sutton, Ken Parzygnat]
5656 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
5657 and Makefile_win32_debug.txt (debug build) that work on Win95.
5658 Run each of the following from the src directory:
5659 nmake /f Makefile_win32.txt # compiles normal build
5660 nmake /f Makefile_win32.txt install # compiles and installs
5661 nmake /f Makefile_win32.txt clean # removes compiled junk

5663 nmake /f Makefile_win32_debug.txt install
5664 nmake /f Makefile_win32_debug.txt clean
5667 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
5668 to build binary distributions. [Lars Eilebrecht]
5670 *) IndexOptions SuppressColumnSorting only turned off making
5671 the column headers anchors; you could still change the display
5672 order by manually adding a '?N=A' or similar query string to the
5673 URL. Now SuppressColumnSorting locks in the sort order so
5674 it can't be overridden this way. [Ken Coar]
5676 *) Added IndexOrderDefault directive to supply a default sort order
5677 for FancyIndexed directory listings. [Ken Coar] PR#1699

5680 [Richard Prinz <richard.prinz@cso.net>] PR#2575
5682 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
5683 search for an underscore on dlsym() (as it's already the case
5684 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
5686 *) Small fix for mod_env.html: The module was documented as to be _not_
5687 compiled into Apache per default, although it _IS_ compiled into
5688 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
5690 *) Instead of fixing a bug in the generation procedure for config.status (a
5691 backslash was missing) we remove the bug together with it's complete
5692 context because the special cases of the past can now no longer occur
5693 because of the recent magic for the --with-layout default.
5694 [Ralf S. Engelschall] PR#3590

5699 [Markus Theissinger <markus.theissinger@gmx.de>]
5701 *) Fix installation procedure: Now that os-inline.c is actually used (a
5702 recently fixed bug prevented this) we need to also install os-include.c
5703 in addition to os.h into the PREFIX/include/ location or building of
5704 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
5706 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
5707 allow us to distinguish between a garbled DSO (or even a file which isn't
5708 an Apache module DSO at all) and a DSO which doesn't match the current
5709 Apache API. [Ralf S. Engelschall] PR#3152
5711 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
5712 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
5713 match case insensitive (this especially avoids nasty patterns like
5714 `[tT][eE][sS][tT]'). Second two additional internal map functions
5715 `escape' and `unescape' were added which can be used to escape/unescape
5716 to/from hex-encodings in URLs parts (this is especially useful in
5717 combination with map lookups).
5718 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
5720 *) Renamed the macro escape_uri() to ap_escape_uri() which was
5721 forgotten (because it was a macro) in the symbol renaming process.
5722 [Ralf S. Engelschall]
5724 *) Fix some inconsistencies related to the scopes of directives. The only
5725 user visible change is that the directives `UseCanonicalName' and
5726 `ContentDigest' now use the (more correct) `Options' scope instead of
5727 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
5729 *) Using DSO, the Server token was being mangled. Specifically, the
5730 module's token was being added first before the Apache token. This
5731 has been fixed. [Jim Jagielski]
5733 *) Major overhaul of mod_negotiation.c, part 2.
5734 - properly handle "identity" within Accept-Encoding.
5735 - allow encoded variants in RVSA negotiation and let them appear in
5736 the Alternates field using the non-standard "encoding" tag-list.
5737 - fixed both negotiation algorithms so that an explicitly accepted
5738 encoding is preferred over no encoding if "identity" is not
5739 included within Accept-Encoding.
5740 - added ap_array_pstrcat() to alloc.c for efficient concatenation
5741 of large substring sequences.
5742 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
5745 *) Major overhaul of mod_negotiation.c, part 1.
5746 - cleanups to mod_negotiation comments and code structure
5747 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
5748 support for everything in the upcoming HTTP/1.1
5749 revision (draft-ietf-http-v11-spec-rev-06.txt).
5750 - language tag matching also handles tags with more than 2
5752 - empty Accept, Accept-Language, Accept-Charset headers are
5753 processed correctly; previously an empty header would make all
5754 values acceptable instead of unacceptable.
5755 - allowed for q values in Accept-Encoding
5756 - added support for transparent content negotiation (rfc2295 and
5757 rfc2296) (though we do not implement all features in these drafts,
5758 e.g. no feature negotiation). Removed old experimental version.
5759 - implemented 'structured entity tags' for better cache correctness
5760 (structured entity tags ensure that caches which can deal with Vary
5761 will (eventually) be updated if the set of variants on the server
5763 - this involved adding a vlist_validator element to request_rec
5764 - this involved adding the ap_make_etag() function to the global API
5765 - modified guessing of charsets used by Apache negotiation algorithm
5766 to guess 'no charset' if the variant is not a text/* type
5767 - added code to sort multiviews variants into a canonical order so that
5768 negotiation results are consistent across backup/restores and mirrors
5769 - removed possibility of a type map file resolving to another type map
5770 file as its best variant

5784 *) For %v log ServerName regardless of the UseCanonicalName
5785 setting (similarly for %p). [Dean Gaudet]
5787 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
5788 rather late (too late for some invocations of TestCompile).
5789 This improves the make environment available to TestCompile and
5790 the *.module scripts. [Martin Kraemer]
5792 *) The hashbang emulation code in ap_execve.c would interpret
5793 #!/hashbang/scripts correctly, but failed to fall back to a
5794 standard shell for scripts which did NOT start with #!
5795 Now SHELL_PATH is started in these cases. [Martin Kraemer]
5797 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
5800 *) Update APXS manual page: some -q option arguments were missing
5801 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
5803 *) Cleanup the command line options: `-?' was documented to show
5804 the usage list but does it with an error because `?' is not a valid
5805 command. OTOH a lot of users expect `-h' to print such a usage list and
5806 instead are annoyed for ages by our huge unreadable list of directives.
5807 So we now changed the command line options this way:
5809 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
5810 very similar to the popular linker option.
5812 Intent: while -l gives the small list of modules, -L now gives the
5813 large list of directives implemented by these modules. This is also
5814 consistent with -v (short version info) and -V (large version info).
5816 Intent: it's now the expected option ;-)
5817 The manual page was adjusted accordingly.
5818 [Ralf S. Engelschall] PR#2714
5820 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
5821 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
5823 *) Removed recently introduced bugs and disfigurements in APACI:
5824 o fixed argument line processing: using $args was broken: It was not
5825 initialized and using args="$args $apc_option" and even args="$args
5826 \"$apc_option\"" fails in the second processing round for any arguments
5827 containing whitespaces. The only correct way is to use the construct
5828 "$@" (but not possible here) or iterate _both_ times over the implicit
5829 argument line (no argument to for-loop) which is what we now use.
5830 o make --with-layout=Apache the default without creating
5831 redundancy (copying the --with-layout block in the argument parsing
5832 loop). We achieve this by using the "$@" construct together with the
5833 `set' command to prepend --with-layout=Apache to the command line in
5834 case --with-layout is not used.
5835 o fixed auto-suffix handling now that config.layout exists.
5836 Paths which are auto-suffixed are marked with a trailing plus sign in
5837 config.layout and every path now can be marked this way (not only the
5838 four paths for which we do it currently). Additionally the suffix is
5839 no longer a static one. Instead it's now `/<target>' where <target> is
5840 the argument of the --target option or per default `httpd'.
5841 o allow also tabs (and only spaces) where we match whitespaces
5842 o various fixes and cleanups related to used shell coding style
5843 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
5844 o trimmed output of --help to fit into 80 columns
5845 [Ralf S. Engelschall]

5869 *) Make generation of src/Configuration.apaci more robust: It failed to
5870 differenciate between modules when one module name was a postfix of
5871 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
5872 just XXX (think about totally non-standard names like "apache_ssl", too).
5873 [Ralf S. Engelschall] PR#3380
5875 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated

5880 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
5881 creates an external package shadow tree in DIR before the local build
5882 shadow tree is generated under DIR. This way one can have the extracted
5883 Apache distribution tree read-only on NFS or CDROM and still build Apache

5903 They can occur multiple times and their arguments (`xxx') are passed AS
5904 IS to the compiler/linker command. [Ralf S. Engelschall]
5906 *) Fixed possible (but harmless in practice) bug in the DBM lookup
5907 procedure of mod_rewrite: very long keys were truncated.
5908 [Ralf S. Engelschall]
5910 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
5911 identifier, currently "Apache" and "GNU" are pre-defined in the file
5912 config.layout. Custom layouts are possible by using FILE:ID as the
5913 argument where the layout ID is taken from FILE.
5915 The config.layout file consists of <Layout ID>..</Layout> sections
5916 where inside those sections "path_variable: path_value" pairs can be
5917 specified. These lines are converted to path_variable='path_value'.
5919 *) Add a DefaultLanguage directive so that files missing a language
5920 extension (e.g., .fr, .de) can be labelled as being some other
5921 default language. DefaultLanguage can appear in <Directory> and
5922 <Files> containers as well as .htaccess files. [Paul Sutton]
5925 *) Fix TARGET configuration when configuring and installing using
5926 APACI configure. TARGET now defines the basename of the configuration
5927 file, startup script, manual page, etc. log_error_core() now reports

6117 response when we already know the final status, which is mighty
6118 useful for PUT responses that result in 302 or 401. [Roy Fielding]
6120 *) Remove extra trailing whitespace from the getline results as part
6121 of the protocol processing, which is extra nice because it works
6122 between continuation lines, is almost no cost in the normal case
6123 of no extra whitespace, and saves memory. [Roy Fielding]
6125 *) Added new HTTP status codes and default response bodies from the
6126 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
6127 HTTP Extension Framework (510) specifications. Did not add the
6128 WebDAV 424 and 425 codes because they are bogus. We don't use any
6129 of these codes yet, but they are now available to 3rd-party modules.

6245 You now must define a BS2000Account name for the server User.
6246 This has fewer security implications than the old approach.
6249 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
6250 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
6251 platform to make the braindead HPUX linker happy. Notice, for the module
6252 DSOs we don't have to use this, because these are loaded manually (and
6253 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

6264 *) Make PrintPath work generically instead of having one version
6265 strictly for OS/2. [Jim Jagielski, Brian Havard]
6267 *) Fix the recently introduced C header file checking: We now use the C
6268 pre-processor pass only (and no longer the complete compiler pass) to
6269 determine whether a C header file exists or not. Because only this way
6270 we're safe against inter-header dependencies (which caused horrible
6271 portability problems). The only drawback is that we now have a CPP
6272 configuration variable which has to be determined first (we do a similar
6273 approach as GNU Autoconf does here). When all fails the user still has
6274 the possibility to override it manually via APACI or src/Configuration.
6275 As a fallback for the header check itself we can directly check the
6276 existance of the file under /usr/include, too.

6309 because our GuessOS is still unaware of Digital UNIX versions and the
6310 -msym is just to optimize the DSO statup time a little bit it's safe and
6311 best when we leave it out now. [Ralf S. Engelschall] PR#2969
6313 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
6314 functions: First all three functions no longer fail on strings containing
6315 "%" chars and second ap_log_printf() no longer does a double-formatting
6316 (instead it directly passes through the message to be formatted to the
6317 real internal formatting function). [Ralf S. Engelschall] PR#2941
6319 *) Allow "Include" directives anywhere in the server config
6320 files (but not .htaccess files). [Ken Coar] PR#2727
6322 *) The proxy was refusing to serve CONNECT requests except to
6323 port 443 (https://) and 563 (snews://). The new AllowCONNECT
6324 directive allows the configuration of the ports to which a
6325 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
6327 *) mod_expires will now act on content that is not sent from a file
6328 on disk. Previously it would never add an Expires: header to
6329 any response that did not come from a file on disk; the only
6330 case where it still doesn't (and can't) add one for that type of
6331 content is if you are using a modification date based setting.

6339 *) Add NameWidth keyword to IndexOptions directive so that the

6343 *) Recognize lowercase _and_ uppercase `uname' results under
6344 SCO OpenServer. [David Coelho <drc@ppt.com>]
6346 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
6347 a common problem of (mis-administrated?) IIS servers, make the apache
6348 proxy immune to these errors (and ignore the duplicates, but log
6349 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
6351 *) The <IfModule and <IfDefine block starting directives now only
6352 allow exactly one argument. Previously, the optional negation
6353 character '!' could be separated by whitespace without a syntax
6354 error being reported, albeit defeating the IfModule functionality
6355 (enclosed directives would ALWAYS be executed). By using the
6356 stricter syntax, these hard-to-track errors can be avoided.
6359 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
6360 cause the standalone FancyIndexing directive to logically OR
6361 into any existing IndexOptions settings rather than wiping
6362 them out. [Ken Coar]
6364 *) Changes in ftp proxy: make URL parsing simpler by using the
6366 + Add display of the "current directory" in cases where it's
6367 different from the supplied path (e.g., ftp://user@host/ lives
6368 in /home/user, not in /, therefore clicking on "../" in the
6369 starting directory might send us to /home/).
6370 + When ftp login fails, (esp. when a user name was part of the
6371 URL already), we now return [401 Unauthorized ] to allow the
6372 browser to pop up an authorization dialog. This makes passwords
6373 slightly less visible (they don't appear in the regular log files)
6374 and implements a functionality that other www proxy servers
6378 *) Triggered by the recent "Via:" header changes, the proxy module would
6379 dump core for replies with invalid headers (e.g., duplicate
6380 "HTTP/1.0 200 OK" lines). These errors are now logged and the
6381 core dump is avoided. Also, broken replies are not cached.
6382 [Martin Kraemer] PR#2914
6384 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
6385 plop gmon.out profile data for each child [Doug MacEachern]

6388 config.status script to be immune against arguments with whitespaces.
6389 [Yves Arrouye <yves@apple.com>] PR#2866
6391 *) Replace the inlined information grabbing stuff for the configuration
6392 adjustment feature (no --without-confadjust) with calls to a new helper
6393 script `buildinfo.sh' which is both more flexible and already proofed to
6394 be more robust against platform differences. This mainly fixes the
6395 recently occured ``sed: command garbled: ...'' problems.

6416 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
6417 5 to 10 because there are some users out there who always have 5 to 8
6418 variables in one RewriteRule and had to patch mod_rewrite.h for every
6419 release. So 15 should be now more than enough, even for them. (I never
6420 needed more than 4 in my RewriteRules ;-)
6421 [Ralf S. Engelschall]
6423 *) Make the proxy generate and understand Via: headers

6430 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
6432 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
6433 provide a way to trace API changes that add functionality but do
6434 not create a compatibility issue for precompiled modules, etc.
6435 See include/ap_mmn.h for more details. [Randy Terbush]
6437 *) Fix suexec installation under `make install root=xxx' situation.
6438 [Ralf S. Engelschall]
6440 *) Extend the output of the -V switch to include the paths of all
6441 compiled-in configuration files, if they were overridden at
6442 compile time, for least astonishment of the user.
6445 *) When READing a request in ExtendedStatus mode, the "old"
6446 vhost, request and client information is not displayed.
6449 *) STATUS is no longer available. Full status information now
6450 run-time configurable using the ExtendedStatus directive.
6453 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
6454 cpu time attacks) in header parsing. Add ap_overlap_tables(),
6455 a function which can be used to perform bulk update operations
6456 on tables in a more efficient manner. [Dean Gaudet]
6458 *) SECURITY: Added compile-time and configurable limits for
6459 various aspects of reading a client request to avoid some simple
6460 denial of service attacks, including limits on maximum request-line
6461 size (LimitRequestLine), number of header fields (LimitRequestFields),
6462 and size of any one header field (LimitRequestFieldsize). Also added
6463 a configurable directive LimitRequestBody for limiting the size of the
6464 request message body. [Roy Fielding]

6467 STATUS not defined. [Jim Jagielski]

6482 *) The 'status' module will now show the process pid's and their
6483 state even without full STATUS accounting. [Jim Jagielski]
6485 *) Restore the client IP address to the error log messages, this
6486 was lost during the transition from 1.2 to 1.3. Add a new
6487 function ap_log_rerror() which takes a request_rec * and
6488 formats it appropriately. [Dean Gaudet] PR#2661
6490 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
6491 whitespace in input lines -- including within quoted strings.
6493 but leading and trailing whitespace should continue to be
6494 stripped [Martin Kraemer]
6496 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
6497 the ugly use of an env. variable and use command-line args for
6498 alternate $PATH. Make more like advanced 'type's as well.
6501 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
6502 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis

6505 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]

6508 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
6509 directory was renamed to src/os/os2/ for consistency.
6510 [Brian Havard, Ralf S. Engelschall]
6512 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
6513 files (here modules) against other DSO files (here shared libraries).
6514 This is done by determining a subset of LIBS which can be safely used for
6515 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
6516 disabled for all platforms to avoid problems with this (experimental)
6517 rule. But we provide it now for those people how ran into problems and
6518 want to came out by forcing linking against DSOs.

6625 documents. [Ralf S. Engelschall] PR#2608
6627 *) Fix broken RANLIB handling in src/Configure (the entry from

6635 *) Add new flags for ap_unparse_uri_components() to make it generate
6636 the scheme://sitepart string only, or to omit the query string.
6639 *) WIN32: Canonicalize ServerRoot before checking to see if it
6640 is a valid directory. The failure to do this caused certain
6641 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
6642 rejected. [Marc Slemko]
6644 *) Global renaming of C header files to both get rid of conflicts with third
6645 party packages and to again reach consistency:
6646 1. conf.h -> ap_config.h
6647 2. conf_auto.h -> ap_config_auto.h \ these are now merged
6648 3. ap_config.h -> ap_config_auto.h / in the config process

6651 Backward compatibility files for conf.h and compat.h were created.
6653 *) mod_mmap_static will no longer take action on requests unless at
6654 least one "mmapfile" directive is present in the configuration.
6655 This experimental module has to do some black magic to operate
6656 inside the current API and thus creates side-effects for other
6657 modules under some circumstances.

6664 *) mod_rewrite created RewriteLock files under the UID of the parent
6665 process, thus the child processes had no write access to the files.
6666 Now a chown() is done on the file to the uid of the children,
6667 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341

6671 accurate platform definitions. This way we no longer have to fiddle with

6715 if the installation prefix didn't already contain "apache", but
6716 it should be because the DSO files are Apache-specific. Now
6717 libexecdir is treated the same way sysconfdir, datadir, localstatedir

6744 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems

6766 httpd is running. This should be more portable than figuring out
6767 which of three dozen different versions of "ps" are installed.
6770 *) WIN32: If we can't figure out how to execute a file in a script
6771 directory, bail out of the request with an error message. [W G Stoddard]
6773 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
6774 these are treated by Win32 as if they are ".." but are not detected by
6775 other machinery within Apache. This is something of a kludge but
6776 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
6778 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
6779 pools and thus pollutes libap (until the pool stuff is moved there).
6782 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
6783 but case-insensitive platforms). New #define for this added to conf.h
6784 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455

6793 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
6794 remove some of the classical hurdles for new users when setting up
6795 Apache. This is done per default because it is useful for the average
6796 user. Package authors can use the --without-confadjust option to disable
6797 these configuration adjustments.
6798 [Ralf S. Engelschall]
6800 *) Added an EXTRA_DEPS configuration parameter which can be used
6801 to add an extra Makefile dependency for the httpd target, for instance
6802 to external third-party libraries, etc.
6803 [Ralf S. Engelschall]
6805 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
6806 as <IfModule>..</IfModule> sections) which can be used to skip or process
6807 contained commands dependend of ``-D PARAMETER'' options on the command
6808 line. This can be used to achieve logical conditions like <IfDefine
6809 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
6810 and thus especially can be used for conditionally loading DSO-based
6811 modules via LoadModule, etc. [Ralf S. Engelschall]
6813 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
6815 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
6817 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
6818 truncated which forced following HTTP headers to be data in the HTTP
6819 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
6822 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
6823 in top-level configure script to avoid sed fails on some platforms (for
6824 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
6825 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
6827 *) Improve performance of directory listings (mod_autoindex) by comparing
6828 integer keys (last-modified and size) as integers rather than converting
6829 them to strings first. Also use a set of explicit byte tests rather
6830 than strcmp() to check for parent directory-ness of an entry. Oh, and
6831 make sure the parent directory (if displayed) is *always* listed first
6832 regardless of the sort key. Overall performance winnage should be good
6833 in CPU time, instruction cache, and memory usage, particularly for large
6834 directories. [Ken Coar]
6836 *) Add a tiny but useful goody to APACI's configure script: The generation
6837 of a config.status script (as GNU Autoconf does) which remembers the used
6838 configure command and hence can be used to restore the configuration by
6839 just re-running this script or for remembering the configuration between
6841 [Ralf S. Engelschall]
6843 *) Add httpd -t (test) option for running configuration syntax tests only.
6844 If something is broken it complains and exits with a return code
6845 non-equal to 0. This can be used manually by the user to check the Apache
6846 configuration after editing and is also automatically used by apachectl
6847 on (graceful) restart command to make sure Apache doesn't die on restarts
6848 because of a configuration which is now broken since the last (re)start.
6849 This way `apachectl restart' can be used inside cronjobs without having
6850 to expect Apache to be falling down. Additionally the httpd -t can be run
6851 via `apachectl configtest'.

6995 programs: ap_spawn_child_err() is used and the Win32 case now uses
6996 CreateProcess() instead of a low-level execl() (which caused problems in
6997 the past under Win32).

7000 *) A few cosmetics and trivial enhancements to APXS to make the
7001 generated Makefile more user friendly. [Ralf S. Engelschall]
7003 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
7004 was updated to use the normal apache error processing, thereby allowing
7005 proxy errors to be treated by ErrorDocument's as well. For this
7006 purpose, a new module-to-core communication variable "error-notes"
7007 was introduced; the proxy (and possibly other modules) communicates
7008 its error text using this variable. Its content is copied to a new
7009 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
7010 The old proxy special error routine ap_proxy_log_uerror()
7011 was replaced by regular ap_log_error() calls, many messages were made

7015 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
7018 *) Transform the configure message "You need root privileges for suEXEC"
7019 from a fatal error into a (more friendly) warning because the building
7020 ("make") of Apache we can allow, of course. Root privileges are needed
7021 only for the installation step ("make install"). So make sure the

7091 *) The Makefiles assumed that DSO files are build via $(LD). This
7092 is broken for two reasons: First we never defined at least LD=ld
7093 somewhere to make sure this works (it was silently assumed that most Make
7094 provide a built-in LD definition - ARGL!) and second using the generic LD
7095 variable is not the truth. Instead a special variable named LD_SHLIB is
7096 reasonable because although "ld" is usually the default, the command for
7097 building DSO files can be "libtool" or even "cc" on some systems.

7100 *) Replace the AddVersionPlatform directive with ServerTokens which
7101 provides for more control over the format of the Server:

7115 - SUBDIRS is now generated in src/Makefile only and not in
7116 Makefile.config because it is a local define for this location.
7117 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
7118 any Makefile but make sure that at least the "-K inline" is kept in
7120 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
7121 - updated the dependencies theirself
7122 - removed not existing SHLIB variable from "clean" targets
7123 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
7124 already exists and OBJS_PIC are also just plain objects and have not
7125 directly to do with "shared" things. The only difference is that they
7126 contain PIC. So OBJS_PIC is the more canonical name.
7127 - Updated the Makefile-dependency lines for OBJS_PIC
7128 - Removed the Makefile-dependency line in Configure to avoid double
7130 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
7131 of xxx.lo as GNU libtool does with its PIC objects
7132 - reduce local complexity in modules Makefile.tmpl by moving the last
7133 existing target "depend" to the generation section in Configure, too.
7134 - removed the historical $(SPACER) which was used in the past together
7135 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
7136 is no longer needed.
7137 - force the build and run of the gen_xxx programs under main/ as the
7138 first step before building the objects because it looks cleaner

7141 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
7144 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
7147 *) WIN32: Don't force ISAPI headers to finish with \n.
7148 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
7150 *) When opening "configuration" files (like httpd.conf, htaccess
7151 and htpasswd), Apache will not allow them to be non-/dev/null
7152 device files. This closes a DoS hole. At the same time,
7153 we use ap_pfopen to open these files to handle timeouts.
7154 [Jim Jagielski, Martin Kraemer]
7156 *) Apache will now log the reason its httpd children exit if they exit
7157 due to an unexpected signal. (It requires a new porting define,
7158 SYS_SIGLIST, which if defined should point to a list of text
7159 descriptions of the signals available. See PORTING.) [Dean Gaudet]
7161 *) WIN32: chdir() doesn't make sense in a multithreaded environment
7162 like WIN32. Before, Win32 CGI's could have had sporadic failures
7163 if a chdir call from one thread was made between another chdir call
7164 and a spawn in another thread. So, for now don't chdir for CGI scripts
7165 in WIN32. The current CGI "spec" is unclear as to whether it's
7166 necessary. Long-term fix is to either serialize the chdir/spawn combo
7167 or use WIN32 native calls to spawn a process. This temp fix was
7168 necessary to remove this as a showstopper for 1.3's release.
7171 *) Cleanup the suEXEC support in APACI and make it more safe:
7172 1. Add big fat hint in INSTALL about risks and to read the
7173 htdocs/manual/suexec.html document before using the suexec-related
7175 2. Make sure the user has at least provided one --suexec-xxxx option
7176 (specifies suEXEC parameters) in addition to --enable-suexec option.
7177 If only --enable-suexec is given APACI stops with a hint to INSTALL
7178 and htdocs/manual/suexec.html documents.
7179 3. Provide two additional --suexec-xxxx options to make the suEXEC
7180 configuration complete (especially for package maintainers who else
7181 had to patch the source tree) by providing ways to configure minimal
7182 UID/GID and safe PATH, too.
7183 [Ralf S. Engelschall]
7185 *) Cleanup of the `configure --shadow' process:
7186 - make sure the configure script creates its temporary files in the
7187 shadow tree to avoid conflicts with parallel configure runs
7188 - removed unnecessary option "-r" from "rm" call for Makefiles
7189 - make sure the configure scripts creates the shadow-wrapper Makefile
7190 only when no shadow trees already exists
7191 - make sure "make distclean" removes the shadow-wrapper Makefile but only
7192 when no more shadow trees exists
7193 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
7194 as fast (in the past it needed 70sec, now it runs just 38sec)
7195 - make sure CVS does not complain about the created files
7196 Makefille.<gnutriple> and directories src.<gnutriple>
7197 [Ralf S. Engelschall]
7199 *) Added the ap_add_version_component() API routine and the
7200 AddVersionPlatform core directive. The first allows modules to
7201 declare themselves in the Server response header field value,
7202 augmenting the SERVER_SUBVERSION define in the Configuration file
7203 with run-time settings (more useful in a loadable-module environment).
7204 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
7205 into the server version string. [Ken Coar] PR#2056
7207 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
7210 *) Emit the "Accept-Range" header for the default handler.
7211 [Brian Behlendorf] PR#1464
7213 *) Add a note to httpd.conf-dist that apache will on some systems fail
7214 to start when the Group # is set to a negative or large positive value.
7217 *) Make sure the module execution order is correct even when some modules
7218 are loaded under runtime (`LoadModule') via the DSO mechanism:
7219 1. The list of loaded modules is now a dynamically allocated one
7220 and not the original statically list from modules.c
7221 2. The loaded modules are now correctly setup by LoadModule for
7222 later use by the AddModule command.
7223 3. When the DSO mechanism for modules is used APACI's `install'
7224 target now enables all created `LoadModule' lines per default because
7225 this is both already expected by the user _and_ needed to avoid
7226 confusion with the next point and reduces the Makefile.tmpl complexity
7227 4. When the DSO mechanism for modules is used, APACI's `install'
7228 target now additionally makes sure the module list is reconstructed
7229 via a complete `ClearModuleList+AddModule...' entry.
7230 5. The support tool `apxs' now also makes sure an AddModule command
7231 is added in addition to the LoadModule command.
7232 6. The modules.c generation was extended to now contain two
7233 comments to make sure no one is confused by the confusing terminology
7234 of loading/linking (we use load=link+load & link=activate instead of
7235 the obvious load=activate & link=link :-( )
7236 This way now there is no longer a difference under execution time between
7237 statically and dynamically linked modules.

7240 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
7241 Big Symbol Renaming. [Ralf S. Engelschall]
7243 *) Add a comment to mod_example.c showing the format of a FLAG command
7246 *) Standardized the time format in mod_status to match that of other
7247 places in the code (e.g. DATE_GMT). PR#1551
7249 *) Fix handling of %Z in timefmt strings for those platforms with no time
7250 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
7253 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
7254 feature compatible with 'UseCanonicalName off' by changing
7255 r->server->server_hostname to ap_get_server_name(). And I changed some
7256 functions which use r->server->port to use ap_get_server_port() instead,
7257 because if there's no Port directive in the config r->server->port is 0.
7260 *) get/set_module_config are trivial enough to be better off inline. Worth
7261 1.5% performance boost. [Dean Gaudet]
7263 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
7264 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
7267 *) [BS2000 security] BS2000 needs an extra authentication to initialize
7268 the task environment to the unprivileged User id. Otherwise CGI scripts
7269 would have a way to gain super user access. [Martin Kraemer]
7271 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
7272 absolute path, only log base name of logging source as is done
7273 in unix. [Martin Kraemer]
7275 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
7276 the encoding type from the Accept-Encoding header (if it's there)
7277 and use it in the response, as that's probably what it'll be expecting.
7278 [Ronald.Tschalaer@psi.ch]
7280 *) Fix to mod_alias: translate_alias_redir is dealing with
7281 a URI, not a filename, so the check for drive letters for win32

7307 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
7308 Additionally the checks for finding the vendor DSO library were moved
7309 from mod_so.c to Configure because first it needs $PLAT etc. and second
7310 mod_so already uses an abstraction layer and does not fiddle with the
7311 vendor functions itself.

7314 *) PORT: Some optimization defines for NetBSD
7315 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
7317 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
7318 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
7320 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
7321 AIX variants should work fine, too. Even AIX 3.x should work). This is
7322 accomplished by using the free DSO emulation code from Jens-Uwe Mager
7323 which we put into a os/unix/os-dso-aix.c file.
7324 [Ralf S. Engelschall]
7326 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
7327 that we should use NET_SIZE_T == int but the include files force size_t.
7328 [Ralf S. Engelschall]
7330 *) Fix two bugs in select() handling in http_main.c.
7333 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
7334 is unset (as it is in situations like timeouts) where it is unclear
7335 whether errno is set or not. [Martin Kraemer]
7337 *) Just having APACI's localstatedir is too general and not enough for most
7338 of the systems. 1.3b6 again required manual APACI patches by package
7339 maintainers from Red Hat and FreeBSD because for their filesystem layout a
7340 little bit more flexibility in configuring the paths is needed. Hence we
7341 provide three additional configure options (--runtimedir, --logfiledir,
7342 --proxycachedir) which now can be used for more granular adjustments if
7343 --localstatedir is not enough to fit the particular needs. As a nice
7344 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
7345 [Ralf S. Engelschall]
7347 *) Make the install root for "make install" in APACI's Makefile overrideable
7348 by package authors. This way we are even more friendly to package
7349 maintainers (especially Debian and Red Hat) who build for the real prefix
7350 via "configure --prefix=/<real>" but use a different local prefix via
7351 "make root=/tmp/apache install" for rolling the package without bristling
7352 the target location on their system.
7353 [Ralf S. Engelschall]
7355 *) Workaround sed limitations in APACI's configure script by now
7356 substituting in chunks of 50 commands (because for instance HPUX's vendor
7357 sed has a limit of max. 98 commands)

7373 o fix IFS handling for _nested_ situation
7374 o fix Perl interpreter search: take first one found instead of last one
7375 o fix DSO consistency check
7376 o print error messages to stderr instead of stdout

7384 initialized correctly before _every_ `for' loop and also restored after
7385 the loops. [Ralf S. Engelschall]
7387 *) Make sure that "make install" doesn't overwrite the `mime.types' and
7388 `magic' files from an existing Apache installation. Because people often
7389 customize these for own MIME and content types.

7396 [Ralf S. Engelschall] PR#2105
7398 *) Let "configure" clear out the users parameters (provided as shell

7425 [Ralf S. Engelschall] PR#2089
7427 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
7429 *) If you start apache with the -S command line option it will dump
7430 out the parsed vhost settings. This is useful for folks trying
7431 to figure out what is wrong with their vhost configuration.
7432 (Other dumps may be added in the future.) [Dean Gaudet]
7434 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
7435 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
7438 *) Because /usr/local/apache is the default prefix the ``configure
7439 --compat'' option no longer has to set prefix, again. This way the
7440 --compat option honors a leading --prefix option. [Lars Eilebrecht]
7442 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
7443 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
7444 to avoid "discard const" warnings. [Ralf S. Engelschall]
7446 *) If a specific handler is set for a file yet the request still
7447 ends up being handled by the default handler, log an error
7448 message before handling it. This catches things such as trying
7449 to use SSIs without mod_include enabled. [Marc Slemko]
7451 *) Fix error logging for the startup case where ap_log_error() still uses
7452 stderr as the target. Now the default log level is honored here, too.

7460 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
7462 Changes with Apache 1.3b6
7464 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
7466 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
7467 interface via the similar but proprietary HP/UX shl_xxx-style system
7468 calls. [Ralf S. Engelschall]
7470 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
7471 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
7472 Make. [Ralf S. Engelschall]
7474 *) ++++ THE BIG SYMBOL RENAMING ++++
7475 To avoid symbol clashes with third-party code compiled into the server,
7476 we globally applied the prefix "ap_" to the following classes of
7478 - Apache provided general functions (e.g., ap_cpystrn)
7479 - Public API functions (e.g., palloc, bgets)
7480 - Private functions which we can't make static (because of
7481 cross-object usage) but should be (e.g., new_connection)
7482 For backward source compatibility a new header file named compat.h was
7483 created which provides defines for the old symbol names and can be used
7484 by third-party module authors.
7487 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
7488 problem under SVR4 is that there is no command flag to force the linker
7489 to export the global symbols of the httpd executable therewith they are
7490 available to the DSO's. Instead of problematic hacks like creating a
7491 dummy.so file (containing dummy references to all global symbols) the
7492 httpd binary is linked against, we use a clean trick stolen from Perl 5:
7493 Placing the Apache core code itself into a DSO library named libhttpd.so.
7494 This way the global symbols _HAVE_ to be exported and thus are available
7495 to any manually loaded DSO's under runtime. To reduce the impact to the
7496 user to null we go even further and create a stub httpd executable which
7497 automatically keeps track of the DSO library loading itself and thus
7498 hides the complete mechanism from the user. Although the generation of
7499 this DSO library is automatically triggered for platforms which
7500 essentially need it (mostly all SVR4-derivates) it can be also enabled
7501 manually via the Rule SHARED_CORE. This can be interesting in the future
7502 where we perhaps exploit this libhttpd.so mechanism for providing nifty
7503 features like graceful upgrades, or whatever.
7504 [Ralf S. Engelschall, Martin Kraemer]
7506 *) Build the libraries before building the rest of the tools. [Ben Hyde]
7508 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
7509 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
7510 conventions while "clean" removes only stuff created by "all" targets,
7511 "distclean" additionally removes the stuff from the configuration
7512 process. This way "make distclean" (hence the name) provides a fresh
7513 source tree as it was for distribution.
7514 [Ralf S. Engelschall]
7516 *) Allow top-level (APACI) Makefile to break on build errors
7517 the same way the src/ subtree Makefiles breaks on them by replacing the
7518 initial APACI sed-subdir-display-kludge with a more clean
7519 variable-passing-solution: variable SDP can optionally hold the subdir
7520 prefix which is consistently used for displaying the subdir movement.
7521 This way even the top-level Makefile can stop correctly on errors as the
7522 user expects. [Ralf S. Engelschall]
7524 *) Fixed ordering of argument checks for RewriteBase directive.
7525 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
7527 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
7528 indicating that a module is being compiled for dynamic loading. Also
7529 remove #define IS_MODULE from modules and add SHARED_MODULE define
7530 to the mak/dsp files. [Alexei Kosut]
7532 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
7533 since we are now logging APLOG_WARNING by default. [Roy Fielding]
7535 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
7537 *) Add documentation file and src/Configuration.tmpl entry for the
7538 experimental mod_mmap_static module. Because although it is and marked as
7539 an experimental one it is distributed and thus should be documented and
7540 prepared for configuration the same way as all others modules.
7541 [Ralf S. Engelschall]
7543 *) Add query (-q) option to apxs support tool to be able to manually query
7544 specific settings from apxs. This is needed for instance when you
7545 manually want to access Apache's header files and you need to assemble
7546 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
7547 [Ralf S. Engelschall]
7549 *) Now src/Configure uses a fallback strategy for the shared object support
7550 on platforms where no explicit information is available: If a Perl
7551 installation exists we ask it about its shared object support and if it's
7552 the dlopen-style one we shamelessly guess the compiler and linker flags
7553 for creating shared objects from Perls knowledge. Of course, the user is
7554 warning about what we are doing and informed that he should send us
7555 the guessed flags when they work. [Ralf S. Engelschall]
7557 *) Provide APACI --without-support option to be able to disable the build
7558 and installation of the support tools from the src/support/ area.
7559 Although its useful to have these installed per default we should provide
7560 a way to compile and install without them for backward-compatibility.
7561 [Ralf S. Engelschall]
7563 *) Add of the new APache eXtenSion (apxs) support tool for building and
7564 installing modules into an _already installed_ Apache package through the
7565 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
7566 this approach actually doesn't need the Apache source tree. The
7567 (APACI-installed) server package is enough, because this now includes the
7568 Apache C header files (PREFIX/include) and the new APXS tool
7569 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
7570 module authors to build their Apache modules _OUTSIDE_ the Apache source
7571 tree while avoiding them to fiddle around with the totally platform
7572 dependend way of compiling DSO files. The tool supports all ranges of
7573 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
7574 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
7575 on-the-fly generate a minimalistic Makefile and sample module for the
7576 first step to provide both a quick success event and to demonstrate the
7577 APXS mechanism to module authors. [Ralf S. Engelschall]
7579 *) Fix core dumps in use of CONNECT in proxy.
7580 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
7582 *) Modify the log directives in httpd.conf-dist files to use CustomLog
7583 so that users have examples of how CustomLog can be used.
7586 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
7587 the Apache distribution tree. Until Apache 1.3 there was no real
7588 out-of-the-box batch-capable build and installation procedure for the
7589 complete Apache package. This is now provided by a top-level "configure"
7590 script and a corresponding top-level "Makefile.tmpl" file. The goal is
7591 to provide a GNU Autoconf-style frontend which is capable to both drive
7592 the old src/Configure stuff in batch and additionally installs the
7593 package with a GNU-conforming directory layout. Any options from the old
7594 configuration scheme are available plus a lot of new options for flexibly
7595 customizing Apache. [Ralf S. Engelschall]
7597 *) The floating point ap_snprintf code wasn't threadsafe.
7598 Had to remove the HAVE_CVT macro in order to do threadsafe
7599 calling of the ?cvt() floating point routines. [Dean Gaudet]
7601 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
7603 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler

7606 *) BUG: Configure was using TCC and CC inconsistently. Make sure
7607 Configure knows which CC we are using. [Jim Jagielski]
7609 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
7610 was defined in a parent directory. [Lars Eilebrecht]
7612 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
7613 a generic printf-style routine that can call arbitrary output
7614 routines. Use this to replace http_bprintf.c. Add new routines
7615 psprintf(), pvsprintf() which allocate the exact amount of memory
7616 required for a string from a pool. Use psprintf() to clean up
7617 various bits of code which used ap_snprintf()/pstrdup().
7620 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
7621 ap_snprintf() has different semantics and formatting codes than
7622 snprintf(). [Dean Gaudet]
7624 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
7625 is necessary on at least Solaris where the /etc/rc?.d scripts
7626 are run with these signals ignored, and "SIG_IGN" settings are
7627 maintained across exec().

7635 existing QUERY_STRING now that mod_proxy was recently changed because of
7636 the new URL parsing stuff. [Ralf S. Engelschall]
7638 *) A few changes to scoreboard definitions which helps gcc generate
7639 better code. [Dean Gaudet]

7646 was a problem and it wasn't taking effect. [Dean Gaudet]
7648 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
7651 *) After a SIGHUP the listening sockets in the parent weren't
7652 properly marked for closure on fork().
7653 [Jürgen Keil <jk@tools.de>] PR#2000
7655 *) Allow %2F in two situations: 1) it is in the query part of the URI,
7656 therefore not exposed to %2F -> '/' translations and 2) the request
7657 is a proxy request, so we're not dealing with a local resource anyway.
7658 Without this, the proxy would fail to work for any URL's with
7659 %2f in them (occurs quite often in
7660 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
7662 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
7664 *) Make the shared object compilation command more portable by avoiding
7665 the direct combination of `-c' & `-o' which is not honored by some
7666 compilers like UnixWare's cc. [Ralf S. Engelschall]
7668 *) WIN32: the proxy was creating filenames missing the last four
7669 characters. While this normally doesn't stop anything from
7670 working, it can result in extra collisions.

7673 *) Now mod_proxy uses the response string (in addition to the response status
7674 code) from the already used FTP SIZE command to setup the Content-Length
7675 header if available. [Ralf S. Engelschall] PR#1183
7677 *) Reanimated the (still undocumented) proxy receive buffer size directive:
7678 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
7679 name was really too generic, added documentation for this directive to
7680 the mod_proxy.html and corrected the hyperlink to it in the
7681 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
7683 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
7684 faster [Martin Kraemer]
7686 *) Make Configure die when you give it an unknown command switch.
7689 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
7690 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
7691 and per default compiled support programs have manual pages - just to
7692 document our stuff a little bit more and to be able to do really
7693 Unix-like installations ;-) [Ralf S. Engelschall]
7695 *) Major cleanups to the Configure script to make it and its generated
7696 Makefiles again readable and maintainable: add SRCDIR option, removed
7697 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
7698 generated sections, consequently added Makefile headers with inheritance
7699 information, added subdir movement messages for easier following where
7700 the build process currently stays (more verbose then standard Make, less
7701 verbose than GNU make), same style to comments in the Configure script,
7702 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
7704 *) Add the new ApacheBench program "ab" to src/support/: This is derived
7705 from the ZeusBench benchmarking program and can be used to determine the
7706 response performance of an Apache installation. This version is
7707 officially licensed with Zeus Technology, Ltd. See the license agreement
7708 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
7709 [Ralf S. Engelschall]
7711 *) API: Various core functions that are definately not part of the API
7712 have been made static, and a few have been marked API_EXPORT. Still
7713 more have been marked CORE_EXPORT and are not intended for general
7714 use by modules. [Doug MacEachern, Dean Gaudet]
7716 *) mod_proxy was not clearing the Proxy-Connection header from
7717 requests; now it does. This did not violate any spec, however
7718 causes poor interactions when you are talking to remote proxies.
7719 [Marc Slemko] PR#1741
7721 *) Various cleanups to the command line interface and manual pages.
7722 [Ralf S. Engelschall]
7724 *) cfg_getline() was not properly handling lines that did not end
7725 with a line termination character. [Marc Slemko] PR#1869, 1909
7727 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
7729 *) Clean up some undocumented behavior of mod_setenvif related to
7730 "merging" two SetEnvIf directives when they match the same header
7731 and regex. Document that mod_setenvif will perform comparisons in
7732 the order they appear in the config file. Optimize mod_setenvif by
7733 doing more work at config time rather than at runtime.
7736 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
7737 to allow for modules to overrule them and to reduce redefinition
7738 warnings [Jim Jagielski]
7740 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
7743 *) Making the hard-coded cross-module function call mime_find_ct() (from
7744 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
7745 checking is really called even for proxy requests except for URLs with
7746 HTTP schemes (because there we can optimize by not running the type
7747 checking hooks due to the fact that the proxy gets the MIME Content-type
7748 from the remote host later). This change cleans up mod_mime by removing
7749 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
7750 especially unbundles mod_proxy and mod_mime. This way they both now can
7751 be compiled as shared objects and are no longer tied together.
7752 [Ralf S. Engelschall]
7754 *) util.c cleanup and speedup. [Dean Gaudet]
7756 *) API: Clarification, pstrndup() will always copy n bytes of the source
7757 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
7759 *) Mark module command_rec and handler_rec structures const so that they
7760 end up in the read-only data section (and are friendlier to systems
7761 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
7763 *) Add check to the "Port" directive to make sure the specified
7764 port is in the appropriate range. [Ben Hyde]
7766 *) Performance improvements to invoke_handler().
7767 [Dmitry Khrustalev <dima@bog.msu.su>]
7769 *) Added support for building shared objects even for library-style modules
7770 (which are built from more than one object file). This now provides the
7771 ability to build mod_proxy as a shared object module. Additionally
7772 modules like mod_example are now also supported for shared object
7773 building because the generated Makefiles now no longer assume there is at
7774 least one statically linked module. [Ralf S. Engelschall]
7776 *) API: Clarify usage of content_type, handler, content_encoding,
7777 content_language and content_languages fields in request_rec. They
7778 must always be lowercased; and the strings pointed to shouldn't
7779 be modified (you must copy them to modify them). Fix a few bugs
7780 related to this. [Dean Gaudet]
7782 *) API: Clarification: except for RAW_ARGS, all command handlers can
7783 treat the char * parameters as permanent, and modifiable. There
7784 is no need to pstrdup() them. Clean up some needless pstrdup().
7787 *) Now mod_so keeps track of which module shared objects with which names
7788 are loaded and thus avoids multiple loading and unloading and irritating
7789 error_log messages. [Ralf S. Engelschall]
7791 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
7792 environment variable in the apache core. But that tweaking interferes
7793 with mod_setenv. So don't tweak if the user has specified an explicit
7794 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
7796 *) rputs() did not calculate r->sent_bodyct properly.
7797 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
7799 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
7800 name, or left unset if this value is unavailable. Apache was setting
7801 it to the IP address when unavailable.
7802 [Tony Finch <fanf@demon.net>] PR#1925
7804 *) Various improvements to the configuration and build support for compiling
7805 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
7806 OSF1 support with GCC and vendor compilers was added. This way shared
7807 object support is now provided out-of-the-box for FreeBSD, Linux,
7808 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
7809 [Ralf S. Engelschall]
7811 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
7812 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
7813 and USE_OS2_SCOREBOARD. [Dean Gaudet]
7815 *) Fix one more special locking problem for RewriteMap programs in
7816 mod_rewrite: According to the documentation of flock(), "Locks are on
7817 files, not file descriptors. That is, file descriptors duplicated
7818 through dup(2) or fork(2) do not result in multiple instances of a lock,
7819 but rather multiple references to a single lock. If a process holding a
7820 lock on a file forks and the child explicitly unlocks the file, the
7821 parent will lose its lock.". To overcome this we have to make sure the
7822 RewriteLock file is opened _AFTER_ the childs were spawned which is now
7823 the case by opening it in the child_init instead of the module_init API
7824 hook. [Ralf S. Engelschall] PR#1029
7826 *) Change to Location and LocationMatch semantics. LocationMatch no
7827 longer lets a single slash match multiple adjacent slashes in the
7828 URL. This change is for consistency with RewriteRule and
7829 AliasMatch. Multiple slashes have meaning in URLs that they do
7830 not have in (some) filesystems. Location on the other hand can
7831 be considered a shorthand for a more complicated regex, and it
7832 does match multiple slashes with a single slash -- which is
7833 also consistent with the Alias directive.
7834 [Dean Gaudet] related PR#1440
7836 *) Fix bug with mod_mime_magic causing certain files, including files
7837 of length 0, to result in no response from the server.
7840 *) The Configure script now generates src/include/ap_config.h which
7841 contains the set of defines used when Apache is compiled on a platform.
7842 This file can then be included by external modules before including
7843 any Apache header files in case they are being built separately from
7844 Apache. Along with this change, a couple of minor changes were
7845 made to make Apache's #defines coexist peacefully with any autoconf
7846 defines an external module might have. [Rasmus Lerdorf]
7848 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
7849 but without any RewriteXXXXX directives. Here mod_rewrite is given no
7850 chance by the API to initialize its per-server configuration and thus
7851 receives the wrong one from the main server. This is now avoided by
7852 remembering the server together with the config structure while
7853 configuring and later assuming there is no config when we see a
7854 difference between the remembered server and the one calling us.
7855 [Ralf S. Engelschall] PR#1790
7857 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
7858 is automatically disabled under configure time when the dbm_xxx functions
7859 are not available. Second, two heavy source code errors in the DBM
7860 support code were fixed. This makes DBM RewriteMap's usable again after
7861 a long time of brokenness. [Ralf S. Engelschall] PR#1696
7863 *) Now all configuration files support Unix-style line-continuation via
7864 the trailing backslash ("\") character. This enables us to write down
7865 complex or just very long directives in a more readable way. The
7866 backslash character has to be really the last character before the
7867 newline and it has not been prefixed by another (escaping) backslash.

7873 *) To deal with modules being compiled and [dynamically] linked
7874 at a different time from the core, the SERVER_VERSION and
7875 SERVER_BUILT symbols have been abstracted through the new
7876 API routines apapi_get_server_version() and apapi_get_server_built().
7879 *) WIN32: Preserve trailing slash in canonical path (and hence
7880 in PATH_INFO). [Paul Sutton, Ben Laurie]
7882 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
7883 depending on the rev of Solaris and what mixture of modules
7884 are in use. So it has been disabled, and Solaris is back to
7885 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
7886 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
7887 up static content only servers. Or it may fail unpredictably.

7890 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
7893 *) API: Rewrite of absoluteURI handling, and in particular how
7894 absoluteURIs match vhosts. Unless a request is a proxy request, a
7895 "http://host" url is treated as if a similar "Host:" header had been
7896 supplied. This change was made to support future HTTP/1.x protocols
7897 which may require clients to send absoluteURIs for all requests.
7899 In order to achieve this change subtle changes were made to the API. In a
7900 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
7901 that the unmodified uri can be retrieved easily. r->proxyreq is not set
7902 by the core, modules must set it during the post_read_request or
7903 translate_names phase.
7905 Plus changes to the virtualhost test suite for absoluteURI testing.
7907 This fixes several bugs with the proxy proxying requests to vhosts
7908 managed by the same httpd.
7911 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
7912 code from mod_rewrite. The vhost matching is now performed by a
7913 globally available function matches_request_vhost(). [Dean Gaudet]

7929 *) API: A new source module main/util_uri.c; It contains a routine
7930 parse_uri_components() and friends which breaks a URI into its component
7931 parts. These parts are stored in a uri_components structure called
7932 parsed_uri within each request_rec, and are available to all modules.
7933 Additionally, an unparse routine is supplied which re-assembles the URI
7934 components back to an URI, optionally hiding the username:password@ part
7935 from ftp proxy requests, and other useful routines. Within the structure,
7936 you find on a ready-for-use basis:
7937 scheme; /* scheme ("http"/"ftp"/...) */
7938 hostinfo; /* combined [user[:password]@]host[:port] */
7939 user; /* user name, as in http://user:passwd@host:port/ */
7940 password; /* password, as in http://user:passwd@host:port/ */
7941 hostname; /* hostname from URI (or from Host: header) */
7942 port_str; /* port string (integer representation is in "port") */
7943 path; /* the request path (or "/" if only scheme://host was given) */
7944 query; /* Everything after a '?' in the path, if present */
7945 fragment; /* Trailing "#fragment" string, if present */
7946 This is meant to serve as the platform for *BIG* savings in
7947 code complexity for the proxy module (and maybe the vhost logic).
7950 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
7951 ${map:key}) available for all location where a string is created in
7952 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
7953 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
7954 possible expansions are consequently usable at all string creation
7955 locations. [Ralf S. Engelschall]
7957 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
7958 and not 1) and the per-virtual-server merging of directives. Now all
7959 directives except `RewriteEngine' and `RewriteOption' are either
7960 completely overridden (default) or completely inherited (when
7961 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

7970 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
7971 (like SunOS and FreeBSD) which don't accept the locking of pipes
7972 directly. A new directive RewriteLock is introduced which can be used to
7973 setup a separate locking file which then is used for synchronization.

7991 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
7992 type but with a special post-processing for the looked-up value: It
7993 parses it into alternatives according to `|' chars and then only one
7994 particular alternative is chosen randomly (this is an essential
7995 functionality needed for balancing between backend-servers when using
7996 Apache as a Reverse Proxy. The looked up value here is a list of
7997 servers). Second, `int' with the built-in maps named `tolower' and
7998 `toupper' which can be used to map URL parts to a fixed case (this is an
7999 essential feature to fix the case of server names when doing mass
8000 virtual-hosting with the help of mod_rewrite instead of using
8001 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
8002 Jay Soffian <jay@cimedia.com>] PR#1631
8004 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
8005 This directive lets Apache adjust the URL in Location-headers on HTTP
8006 redirect responses sent by the remote server. This way the virtually
8007 mapped area is no longer left on redirects and thus by-passed which is
8008 especially essential when running Apache as a reverse proxy.

8078 *) Various errors from select() and accept() in child_main() would
8079 result in an infinite loop. It seems these two tickle kernel
8080 or library bugs occasionally, and result in log spammage and
8081 a generally bad scene. Now the child exits immediately,
8082 which seems to be a good workaround.

8109 Changes with Apache 1.3b4
8111 *) The module structure was modified to include a *dynamic_load_handle
8112 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
8113 has been bumped accordingly. [Paul Sutton]
8115 *) All BrowserMatch directives mentioned in
8116 htdocs/manual/known_client_problems.html are in the default
8117 configuration files. [Lars Eilebrecht]
8119 *) MiNT port update. [Jan Paul Schmidt]
8121 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
8122 equivalent, similarly for x-compress and compress. Apache
8123 now ignores a leading x- when comparing encodings. It also
8124 preserves the encoding the client requests (for example if
8125 it requests x-gzip, then Apache will respond with x-gzip
8126 in the Content-Encoding header).
8127 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
8129 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
8131 *) Added mod_so module to support dynamic loading of modules on Unix
8132 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
8133 instead of AddModule in Configuration to build shared modules
8134 [Sameer Parekh, Paul Sutton]
8136 *) Minor cleanups to r->finfo handling in some modules.
8139 *) Abstract read()/write() to ap_read()/ap_write().
8140 Makes it easier to add other types of IO code such as SFIO.
8143 *) API: Generalize default_port manipulations to make support of
8144 different protocols easier. [Ben Laurie, Randy Terbush]
8146 *) There are many cases where users do not want Apache to form
8147 self-referential urls using the "canonical" ServerName and Port.
8148 The new UseCanonicalName directive (default on), if set to off
8149 will cause Apache to use the client-supplied hostname and port.

8154 PR#315, 459, 485, 1433
8156 *) Yet another rearrangement of the source tree.. now all the common
8157 header files are in the src/include directory. The -Imain -Iap
8158 references in Makefiles have been changed to the simpler -Iinclude
8159 instead. In addition to simplifying the build a little bit, this
8160 also makes it clear when a module is referencing something in a
8161 other than kosher manner (e.g., the proxy including mod_mime.h).
8162 Module-private header files (the proxy, mod_mime, the regex library,
8163 and mod_rewrite) have not been moved to src/include; nor have
8164 the OS-abstraction files. [Ken Coar]
8166 *) Fix a bug where r->hostname didn't have the :port stripped
8167 from it. [Dean Gaudet]
8169 *) Tweaked the headers_out table size, and the subprocess_env
8170 table size guess in rename_original_environment(). Added
8171 MAKE_TABLE_PROFILE which can help discover make_table()
8172 calls that use too small an initial guess, see alloc.c.
8175 *) Options and AllowOverride weren't properly merging in the main
8176 server setting inside vhosts (only an issue when you have no
8177 <Directory> or other section containing an Options that affects
8178 a request). Options +foo or -foo in the main_server wouldn't
8179 affect the main_server's lookup defaults. [Dean Gaudet]
8181 *) Variable 'cwd' was being used pointlessly before being set.
8184 *) r->allowed handling cleaned up in the standard modules.
8187 *) Some case-sensitivity issues cleaned up to be consistent with
8188 RFC2068. [Dean Gaudet]
8190 *) SIGURG doesn't exist everywhere.
8191 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8193 *) mod_unique_id was erroneously generating a second unique id when
8194 an internal redirect occured. Such redirects occur, for example,
8195 when processing a DirectoryIndex match. [Dean Gaudet]
8197 *) API: table_add, table_merge, and table_set include implicit pstrdup()
8198 of the key and value. But in many cases this is not required
8199 because the key/value is a constant, or the value has been built
8200 by pstrcat() or other similar means. New routines table_addn,
8201 table_mergen, and table_setn have been added to the API, these
8202 routines do not pstrdup() their arguments. The core code and
8203 standard modules were changed to take advantage of these routines.
8204 The resulting server is up to 20% faster in some situations.
8206 Note that it is easy to get code subtly wrong if you pass a key/value
8207 which is in a pool other than the pool of the table. The only
8208 safe thing to do is to pass key/values which are in the pool of
8209 the table, or in one of the ancestors of the pool of the table.
8210 i.e. if the table is part of a subrequest, a value from the main
8211 request's pool is OK since the subrequest pool is a sub_pool of the
8212 main request's pool (and therefore has a lifespan at most as long as
8213 the main pool). There is debugging code which can detect improper
8214 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
8215 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
8217 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
8218 which don't exist on disk more gracefully; handles vhosts properly.
8219 Update documentation to reflect the code -- if there's no
8220 MimeMagicFile directive then the module is not enabled.
8223 *) PORT: Some older *nix dialects cannot automatically start scripts
8224 which begin with a #! interpreter line (the shell starts the scripts
8225 appropriately on these platforms). Apache now supports starting of
8226 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
8227 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
8230 *) API: "typedef array_header table" removed from alloc.h, folks should
8231 have been writing to use table as if it were an opaque type, but even
8232 some standard modules got this wrong. By changing the definition
8233 to "typedef struct table table" module authors will receive compile
8234 time warnings that they're doing the wrong thing. This change
8235 facilitates future changes with more sophisticated table
8236 structures. Specifically, module authors should be using table_elts()
8237 to get access to an array_header * for the table. [Dean Gaudet]
8239 *) API: Renamed new_connection() to avoid namespace collision with LDAP
8240 library routines. [Ken Coar, Rasmus Lerdorf]
8242 *) WIN32: mod_speling is now available on the Win32 platform.
8245 *) For clarity the following compile time definition was changed:
8247 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
8249 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
8250 and not be a general notice that the OS has mmap(). Now the
8251 HAVE_MMAP/SHMGET #defines strictly are informational that the
8252 OS has that method of shared memory; the type to use for
8253 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
8254 and USE_SHMGET_SCOREBOARD). This allows outside modules to
8255 determine if shared memory is available and allows Apache
8256 to determine the best method to use for the scoreboard.
8259 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
8260 as do various earlier versions. It should be safe on all versions.

8262 the slack code. A few other cleanups for Unixware.

8266 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
8268 *) When die() happens we need to eat any request body if one exists.
8269 Otherwise we can't continue with a keepalive session. This shows up
8270 as a POST problem with MSIE 4.0, typically against pages which are
8271 authenticated. [Roy Fielding] PR#1399
8273 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
8274 header will be passed to CGIs. This is generally a security hole, so

8282 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
8284 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
8285 The choice of flock vs. fcntl was made based on timings which showed that
8286 even on non-NFS, non-exported filesystems fcntl() was an order of
8287 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
8288 that single socket users will see no difference. [Dean Gaudet] PR#467
8290 *) "File does not exist" error message was erroneously including the
8291 errno. [Marc Slemko]
8293 *) Improve the warning message generated when a client drops the
8294 connection (hits stop button, etc.) during a send. [Roy Fielding]
8296 *) Defining GPROF will disable profiling in the parent and enable it
8297 in the children. If you're profiling under Linux this is pretty much
8298 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
8300 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

8310 *) Some const declarations in mod_imap.c that were added for debugging
8311 purposes caused some compilers heartburn without adding any
8312 significant value, so they've been removed. [Ken Coar]
8314 *) The src/main/*.h header files have had #ifndef wrappers added to
8315 insulate them against duplicate calls if they get included through
8316 multiple paths (e.g., in .c files as well as other .h files).
8319 *) The libap routines now have a header file for their prototypes,
8320 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
8322 *) mod_autoindex with a plaintext header file would emit the <PRE>
8323 start-tag before the HTML preamble, rather than after the preamble
8324 but before the header file contents. [John Van Essen <jve@gamers.org>]
8327 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8328 only an issue on systems without a MAXDNAME define or where
8329 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8331 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8332 is used to read various types of files such as htaccess and
8333 htpasswd files. [Marc Slemko]
8335 *) SECURITY: Ensure that the buffer returned by ht_time is always
8336 properly null terminated. [Marc Slemko]
8338 *) The "Connection" header could be sent back with multiple "close"
8339 tokens. Not an error, but a waste.
8340 [Ronald.Tschalaer@psi.ch] PR#1683
8342 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
8343 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
8345 *) "basic" auth needs a case-insensitive comparison.
8346 [Ronald.Tschalaer@psi.ch] PR#1666
8348 *) For maximum portability, the environment passed to CGIs should
8349 only contain variables whose names match the regex
8350 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
8351 underscores over any character outside the regex. This
8352 affects HTTP_* variables, in a way that should be backward
8353 compatible for all the standard headers; and affects variables
8354 set with SetEnv/BrowserMatch and similar directives.

8393 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8394 including fixing a possible buffer overflow. [Dean Gaudet]
8396 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
8397 (connections are not dropped). Code can handle graceful restarts
8398 (but there is as yet no way to signal this to Apache). Various
8399 other cleanups. [Paul Sutton]
8401 *) The aplog_error changes specific to 1.3 introduced a buffer
8402 overrun in the (now legacy) log_printf function. Fixed.
8405 *) mod_digest didn't properly deal with proxy authentication. It
8406 also lacked a case-insensitive comparision of the "Digest"
8407 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
8409 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
8411 *) A few cleanups in mod_info to make it thread-safe, and remove an

8435 *) Interim (slow) fix for p->sub_pool critical sections in
8436 alloc.c (affects win32 only). [Ben Hyde]
8438 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
8440 *) send_fd_length() did not calculate total_bytes_sent properly.
8441 [Ben Reser <breser@regnow.com>] PR#1366
8443 *) The bputc() macro was not properly integrated with the chunking
8444 code; in many cases modules using bputc() could cause completely
8445 bogus chunked output. (Typically this will show up as problems
8446 with Internet Explorer 4.0 reading a page, but other browsers
8447 having no problem.) [Dean Gaudet]
8449 *) Create LARGE_WRITE_THRESHOLD define which determines how many
8450 bytes have to be supplied to bwrite() before it will consider
8451 doing a writev() to assemble multiple buffers in one system
8452 call. This is critical for modules such as mod_include,
8453 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
8454 strings in some cases. The result would be extra effort
8455 setting up writev(), and in many cases extra effort building
8456 chunks. The default is 31, it can be overriden at compile
8459 *) Move the gid switching code into the child so that log files
8460 and pid files are opened with the root gid.

8465 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
8467 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
8468 so the functionality is available to applications other than the
8469 server itself (like the src/support tools). [Ken Coar]
8471 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
8472 the libap consolidation work. [Ken Coar]
8474 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not

8576 *) It was necessary to distinguish between resources which are
8577 allocated in the parent, for cleanup in the parent, and resources
8578 which are allocated in each child, for cleanup in each child.
8579 A new pool was created which is passed to the module child_init
8580 and child_exit functions; modules are free to register per-child
8581 cleanups there. This fixes a bug with reliable piped logs.
8584 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
8585 unless it was also doing FancyIndexes, but it displayed the
8586 HeaderName file at the top under all circumstances. It now shows
8587 the ReadmeName file for simple indices, too, as it should.

8591 read the file. [Ben Hyde <bhyde@gensym.com>]
8593 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
8594 Now the rewriting engine (the heart of mod_rewrite) is organized more
8595 straight-forward, first time well documented and reduced to the really
8596 essential parts. All redundant cases were stripped off and processing now
8597 is the same for both per-server and per-directory context with only a
8598 minimum difference (the prefix stripping in per-dir context). As a
8599 side-effect some subtle restrictions and two recently discovered problems
8600 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
8601 context and restrictions on the substitution URL on redirects.
8602 Additionally some minor source cleanups were done.

8757 Changes with Apache 1.3b2 (there is no 1.3b1)
8759 *) TestCompile was not passing $LIBS [Dean Gaudet]
8761 *) Makefile.tmpl was not using $CFLAGS in the link phase.
8764 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
8765 rudimentary memory debugger which can be used on live servers with
8766 low impact -- it sets all allocated and freed memory bytes to 0xa5.
8767 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
8768 and free() for each object. This is far more expensive and should
8769 only be used for testing with tools such as Electric Fence and
8770 Purify. See main/alloc.c for more details. [Dean Gaudet]
8772 *) Configure uses a sh trap and didn't set its exitcode properly.
8773 [Dean Gaudet] PR#1159
8775 *) Yet another vhost revamp. Add the NameVirtualHost directive which
8776 explicitly lists the ip:port pairs that are to be used for name-vhosts.
8777 From a given ip:port, regardless what the Host: header is, you can
8778 only reach the vhosts defined on that ip:port. The precedence of
8779 vhosts was reversed to match other precedences in the config --
8780 the earlier vhosts override the later vhosts. All vhost matching was
8781 moved into http_vhost.[ch]. [Dean Gaudet]
8783 *) ap_inline can be used to force inlining. GNUC __attribute__() can
8784 be used for whatever reason is appropriate (i.e. format() warnings
8785 for printf style functions). Both are enabled only with
8786 gcc >= 2.7.x (so that we have fewer support issues with older
8787 versions). [Dean Gaudet]
8789 *) Fix support for Proxy Authentication (we were testing the response
8790 status too early). [Marc Slemko]
8792 *) CoreDumpDirectory directive directs where the core file is

8797 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
8799 *) When booting, apache will now detach itself from stdin, stdout,
8800 and stderr. stderr will not be detached until after the config
8801 files have been read so you will be able to see initial error
8802 messages. After that all errors are logged in the error_log.
8803 This makes it more convenient to start apache via rsh, ssh,
8804 or crontabs. [Dean Gaudet] PR#523
8806 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.

8810 *) send_fb would not detect aborted connections in some situations.

8816 *) mod_imap should only handle GET methods. [Jay Bloodworth]
8818 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8820 *) mod_autoindex improperly counted &escapes; as more than one
8821 character in the description. It also improperly truncated
8822 descriptions that were exactly the maximum length.
8825 *) RedirectMatch was not properly escaping the result (PR#1155). Also
8826 "RedirectMatch /advertiser/(.*) $1" is now permitted.
8829 *) mod_include now uses symbolic names to check for request success
8830 and return HTTP errors, and correctly handles all types of
8831 redirections (previously it only did temporary redirect correctly).
8832 [Ken Coar, Roy Fielding]
8834 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8835 r->filename. Since those two are meant to be in sync with each other
8836 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

8845 reporting a select error over and over.
8846 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
8848 *) Fixed error in proxy_util.c when looping through multiple host IP
8849 addresses. [Lars Eilebrecht] PR#974
8851 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
8852 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
8853 bytes before writing, but it will never split a log entry across a
8854 buffer boundary. [Dean Gaudet]
8856 *) API: the short_score record has been split into two pieces, one which
8857 the parent writes on, and one which the child writes on. As part of
8858 this change the get_scoreboard_info() function was removed, and
8859 scoreboard_image was exported. This change fixes a race condition
8860 in file based scoreboard systems, and speeds up changes involving the
8861 scoreboard in earlier 1.3 development. [Dean Gaudet]
8863 *) API: New register_other_child() API (see http_main.h) which allows
8864 modules to register children with the parent for maintenance. It
8865 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
8867 *) API: New piped_log API (see http_log.h) which implements piped logs,
8868 and will use register_other_child to implement reliable piped logs
8869 when it is available. The reliable piped logs part can be disabled
8870 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
8871 logs is only available on Unix. [Dean Gaudet]
8873 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
8874 meets_conditions(). This allows conditional HTTP selection to be
8875 handled separately from the storing of the header fields, and provides
8876 the ability for CGIs to set their own ETags for conditional checking.
8877 [Ken Coar, Roy Fielding] PR#895
8879 *) Changes to mod_log_config to allow naming of format strings.
8880 Format nicknames are defined with "LogFormat fmt nickname", and can
8881 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
8884 *) New module, "mod_speling", which can help find files even when
8885 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
8887 *) API: New function child_terminate() triggers the child process to
8888 exit, while allowing the child finish what it needs to for the
8889 current request first.
8890 [Doug MacEachern, Alexei Kosut]
8892 *) Windows now defaults to using full status reports with mod_status.
8893 [Alexei Kosut] PR #1094
8895 *) *Really* disable all mod_rewrite operations if the engine is off.
8896 Some things (like RewriteMaps) were checked/performed even if they
8897 weren't supposed to be. [Ken Coar] PR #991
8899 *) Implement a new timer scheme which eliminates the need to call alarm() all
8900 the time. Instead a counter in the scoreboard for each child is used to
8901 show when the child has made forward progress. The parent samples this
8902 counter every scoreboard maintenance cycle, and issues SIGALRM if no
8903 progress has been made in the timeout period. This reduces the static
8904 request best-case syscall count to 22 from 29. This scheme is only
8905 used by systems with memory-based scoreboards. [Dean Gaudet]
8907 *) The proxy now properly handles CONNECT requests which are sent
8908 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
8910 *) A script called apachectl has been added to the support
8911 directory. This script allows you to do things such as
8912 "apachectl start" and "apachectl restart" from the command
8915 *) Modules and core routines are now put into libraries, which
8916 simplifies the link line tremendously (among other advantages).
8919 *) Some of the MD5 names defined in Apache have been renamed to have
8920 an `ap_' prefix to avoid conflicts with routines supplied by
8921 external libraries. [Ken Coar]
8923 *) Removal of mod_auth_msql.c from the distribution. There are many
8924 other options for databases today. Rather than offer one option,
8925 offer none at this time. mod_auth_msql and other SQL database
8926 authentication modules can be found at the Apache Module Registry.
8927 http://modules.apache.org/ It would be nice to offer a generic
8928 mod_auth_sql option in the near future.
8930 *) PORT: BeOS support added [Alexei Kosut]
8932 *) Configure no longer accepts the -make option, since it creates
8933 Makefile on the fly based on Makefile.tmpl and Configuration.
8935 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
8936 of forcibly killing off all its processes and exiting without
8937 cleaning up. [Alexei Kosut]
8939 *) API: A new field in the request_rec, r->mtime, has been added to
8940 avoid gratuitous parsing of date strings. It is intended to hold
8941 the last-modified date of the resource (if applicable). An
8942 update_mtime() routine has also been added to advance it if
8943 appropriate. [Roy Fielding, Ken Coar]
8945 *) SECURITY: If a htaccess file can not be read due to bad permissions,
8946 deny access to the directory with a HTTP_FORBIDDEN. The previous
8947 behavior was to ignore the htaccess file if it could not be read.
8948 This change may make some setups with unreadable htaccess files
8949 stop working. [Marc Slemko] PR#817
8951 *) Add aplog_error() providing a mechanism to define levels of
8952 verbosity to the server error logging. This addition also provides
8953 the ability to log errors using syslogd. Error logging is configurable
8954 on a per-server basis using the LogLevel directive. Conversion
8955 of log_*() in progress. [Randy Terbush]
8957 *) Further enhance aplog_error() to not log filename, line number, and
8958 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
8960 *) WIN32: Canonicalise filenames under Win32. Short filenames are
8961 converted to long ones. Backslashes are converted to forward
8962 slashes. Case is converted to lower. Parts of URLs that do not
8963 correspond to files are left completely alone. [Ben Laurie]
8965 *) PORT: 2 new OSs added to the list of ports:
8966 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
8967 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
8969 *) Add the server version (SERVER_VERSION macro) to the "server
8970 configured and running" entry in the error_log. Also build an
8971 object file at link-time that contains the current time
8972 (SERVER_BUILT global const char[]), and include that in the
8975 *) Set r->headers_out when sending responses from the proxy.
8976 This fixes things such as the logging of headers sent from
8977 the proxy. [Marc Slemko] PR#659
8979 *) support/httpd_monitor is no longer distributed because the
8980 scoreboard should not be file based if at all possible. Use
8981 mod_status to see current server snapshot.
8983 *) (set_file_slot): New function, allowing auth directives to be
8984 independent of the server root, so the server documents can be
8985 moved to a different directory or machine more easily.
8986 [David J. MacKenzie]
8988 *) If no TransferLog is given explicitly, decline
8989 to log. This supports coexistence with other logging modules,
8990 such as the custom one that UUNET uses. [David J. MacKenzie]
8992 *) Check for titles in server-parsed HTML files.
8993 Ignore leading newlines and returns in titles. The old behavior
8994 of replacing a newline after <title> with a space causes the
8995 title to be misaligned in the listing. [David J. MacKenzie]
8997 *) Change mod_cern_meta to be configurable on a per-directory basis.
8998 [David J. MacKenzie]
9000 *) Add 'Include' directive to allow inclusion of configuration
9001 files within configuration files. [Randy Terbush]
9003 *) Proxy errors on connect() are logged to the error_log (nothing
9004 new); now they include the IP address and port that failed
9005 (*that's* new). [Ken Coar, Marc Slemko] PR#352
9007 *) Various architectures now define USE_MMAP_FILES which causes
9008 the server to use mmap() for static files. There are two
9009 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
9010 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
9011 number of bytes written in one cycle from a single mmap()d object,
9012 default 32768). [Dean Gaudet]
9014 *) API: Added post_read_request API phase which is run right after reading
9015 the request from a client, or right after an internal redirect. It is
9016 useful for modules setting environment variables that depend only on
9017 the headers/contents of the request. It does not run during subrequests
9018 because subrequests inherit pretty much everything from the main
9019 request. [Dean Gaudet]
9021 *) Added mod_unique_id which is used to generate a unique identifier for
9022 each hit, available in the environment variable UNIQUE_ID.
9025 *) init_modules is now called after the error logs have been opened. This
9026 allows modules to emit information messages into the error logs.
9029 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9030 information for case where proxy module is not available. [Marc Slemko]
9032 *) PORT: Apache has need for mutexes to serialize its children around
9033 accept. In prior versions either fcntl file locking or flock file
9034 locking were used. The method is chosen by the definition of
9035 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
9036 and FLOCK for flock(). New options have been added:
9037 - SYSVSEM to use System V style semaphores
9038 - PTHREAD to use POSIX threads (appears to work on Solaris only)
9039 - USLOCK to use IRIX uslock
9040 Based on timing various techniques, the following changes were made
9042 - Linux 2.x uses flock instead of fcntl
9043 - Solaris 2.x uses pthreads
9044 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
9045 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
9046 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
9047 Martijn Koster <m.koster@pobox.com>]
9049 *) PORT: The semantics of accept/select make it very desirable to use
9050 mutexes to serialize accept when multiple Listens are in use. But
9051 in the case where only a single socket is open it is sometimes
9052 redundant to serialize accept(). Not all unixes do a good job with
9053 potentially dozens of children blocked on accept() on the same
9054 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
9055 the server will avoid serialization when listening on only one socket,
9056 and use serialization when listening on multiple sockets.
9057 [Dean Gaudet] PR#467
9059 *) Configure changes: TestLib replaced by TestCompile, which has
9060 some additional capability (such as doing a sanity check of
9061 the compiler and flags selected); the version of Solaris is now
9062 available via the #define value of SOLARIS2; IRIX n32bit libs
9063 now supported and selectable by new Configuration Rule: IRIXN32;
9064 We no longer default to -O2 optimization. [Jim Jagielski]
9066 *) Updated Configure: Configuration now uses AddModule to specify
9067 module source or binary file location, relative to src directory.
9068 Modules can be dropped into modules/extra, or in their own
9069 directory, and modules can come with a Makefile or Configure can
9070 create one. Modules can add compiler or library information to
9071 generated Makefiles. [Paul Sutton]
9073 *) Source core re-organisation: distributed modules are now in
9074 modules/standard. All other source code is in main. OS-specific
9075 code is in os/{unix,emx,win32} directories. [Paul Sutton]
9077 *) mod_browser has been removed, since it's replaced by mod_setenvif.
9080 *) Fix another long-standing bug in sub_req_lookup_file where it would
9081 happily skip past access checks on subdirectories looked up with
9082 relative paths. (It's used by mod_dir, mod_negotiation,
9083 and mod_include.) [Dean Gaudet]
9085 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
9086 N is the number of <Directory> sections, and M is the number of
9087 components in the filename of an object.
9089 To achieve this optimization the following config changes were made:
9090 - Wildcards (* and ?, not the regex forms) in <Directory>s,
9091 <Files>s, and <Location>s now treat a slash as a special
9092 character. For example "/home/*/public_html" previously would
9093 match "/home/a/andrew/public_html", now it only matches things
9094 like "/home/bob/public_html". This mimics /bin/sh behaviour.
9095 - It's possible now to use [] wildcarding in <Directory>, <Files>
9097 - Regex <Directory>s are applied after all non-regex <Directory>s.
9101 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
9102 and corrupted paths. [Dean Gaudet]
9104 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
9105 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
9106 be accessed now via backreferences $1..$9 in RewriteConds test-against
9107 strings in addition to RewriteRules subst string. Second the grouped
9108 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
9109 via backreferences %1..%9 both in following RewriteCond test-against
9110 strings and RewriteRules subst string. This provides maximum flexibility
9111 through the use of backreferences.
9112 Additionally the rewriting engine was cleaned up by putting common
9113 code to the new expand_backrefs_inbuffer() function.
9114 [Ralf S. Engelschall]
9116 *) When merging the main server's <Directory> and <Location> sections into
9117 a vhost, put the main server's first and the vhost's second. Otherwise
9118 the vhost can't override the main server. [Dean Gaudet] PR#717
9120 *) The <Directory> code would merge and re-merge the same section after
9121 a match was found, possibly causing problems with some modules.
9124 *) ip-based vhosts are stored and queried using a hashing function, which
9125 has been shown to improve performance on servers with many ip-vhosts.
9126 Some other changes had to be made to accommodate this:
9127 - the * address for vhosts now behaves like _default_
9128 - the matching process now is:
9129 - match an ip-vhost directly via hash (possibly matches main
9131 - if that fails, just pretend it matched the main server
9132 - if so far only the main server has been matched, perform
9133 name-based lookups (ServerName, ServerAlias, ServerPath)
9134 *only on name-based vhosts*
9135 - if they fail, look for _default_ vhosts
9136 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
9138 *) dbmmanage overhaul:
9139 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
9140 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
9141 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
9142 - provide better seed for rand
9143 - prompt for password as per getpass(3) (turn off echo, read from
9145 - use "newstyle" crypt based on $Config{osname} ($^O)
9146 - will not add a user if already in database, use new `update' command
9148 - added `check' command to check a users' password
9149 - added `import' command to convert existing password text-files or
9150 dbm files exported with `view'
9151 - more descriptive usage, general cleanup, 'use strict' clean, etc.
9154 *) Added psocket() which is a pool form of socket(), various places within
9155 the proxy weren't properly blocking alarms while registering the cleanup
9156 for its sockets. bclose() now uses pclose() and pclosesocket(). There
9157 was a bug where the client socket was being close()d twice due a still
9158 registered cleanup. [Dean Gaudet]
9160 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
9163 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
9164 [Jason Venner <jason@idiom.com>] PR#667
9166 *) Enable ``=""'' for RewriteCond directives to match against
9167 the empty string. This is the preferred way instead of ``^$''.
9168 [Ralf S. Engelschall]
9170 *) Fixed an infinite loop in mod_imap for references above the server root
9171 [Dean Gaudet] PR#748
9173 *) mod_proxy now has a ReceiveBufferSize directive, similar to
9174 SendBufferSize, so that the TCP window can be set appropriately
9175 for LFNs. [Phillip A. Prindeville]
9177 *) mod_browser has been replaced by the more general mod_setenvif
9178 (courtesy of Paul Sutton). BrowserMatch* directives are still
9179 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
9180 UnSetEnvIfZero directives. [Ken Coar]
9182 *) "HostnameLookups double" forces double-reverse DNS to succeed in
9183 order for remote_host to be set (for logging, or for the env var
9184 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
9187 *) mod_access overhaul:
9188 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
9189 and cidr syntax (i.e. 10.1.0.0/16). PR#762
9190 - Critical path was sped up by pre-computing a few things at config time.
9191 - The undocumented syntax "allow user-agents" was removed,
9192 the replacement is "allow from env=foobar" combined with mod_browser.
9193 - When used with hostnames it now forces a double-reverse lookup
9194 no matter what the directory settings are. This double-reverse
9195 doesn't affect any of the other routines that use the remote
9196 hostname. In particular it's still passed to CGIs and the log
9197 without the double-reverse check. Related PR#860.
9200 *) When a large bwrite() occurs (larger than the internal buffer size),
9201 while there is already something in the buffer, apache will combine
9202 the large write and the buffer into a single writev(). (This is
9203 in anticipation of using mmap() for reading files.)
9206 *) In obscure cases where a partial socket write occurred while chunking,
9207 Apache would omit the chunk header/footer on the next block. Cleaned
9208 up other bugs/inconsistencies in error conditions in buff.c. Fixed
9209 a bug where a long pause in DNS lookups could cause the last packet
9210 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
9212 *) API: Added child_exit function to module structure. This is called
9213 once per "heavy-weight process" just before a server child exit()'s
9214 e.g. when max_requests_per_child is reached, etc.
9215 [Doug MacEachern, Dean Gaudet]
9217 *) mod_include cleanup showed that handle_else was being used to handle
9218 endif. It didn't cause problems, but it was cleaned up too.
9221 *) mod_cern_meta would attempt to find meta files for the directory itself
9222 in some cases, but not in others. It now avoids it in all cases.
9225 *) mod_mime_magic would core dump if there was a decompression error.
9226 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
9228 *) PORT: some variants of DGUX require -lsocket -lnsl
9229 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
9231 *) mod_autoindex now allows sorting of FancyIndexed directory listings
9232 by the various fields (name, size, et cetera), either in ascending
9233 or descending order. Just click on the column header. [Ken Coar]
9235 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
9236 CPUs like the Alpha. Apache still stores ints in pointers, but that's
9237 the relatively safe direction. [Dean Gaudet] PR#344
9239 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
9240 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
9242 *) child_main avoids an unneeded call to select() when there is only one
9243 listening socket. [Dean Gaudet]
9245 *) In the event that the server is starved for idle servers it will
9246 spawn 1, then 2, then 4, ..., then 32 servers each second,
9247 doubling each second. It'll also give a warning in the errorlog
9248 since the most common reason for this is a poor StartServers
9249 setting. The define MAX_SPAWN_RATE can be used to raise/lower
9250 the maximum. [Dean Gaudet]
9252 *) Apache now provides an effectively unbuffered connection for
9253 CGI scripts. This means that data will be sent to the client
9254 as soon as the CGI pauses or stops output; previously, Apache would
9255 buffer the output up to a fixed buffer size before sending, which
9256 could result in the user viewing an empty page until the CGI finished
9257 or output a complete buffer. It is no longer necessary to use an
9258 "nph-" CGI to get unbuffered output. Given that most CGIs are written
9259 in a language that by default does buffering (e.g. perl) this
9260 shouldn't have a detrimental effect on performance.
9262 "nph-" CGIs, which formerly provided a direct socket to the client
9263 without any server post-processing, were not fully compatible with
9264 HTTP/1.1 or SSL support. As such they would have had to implement
9265 the transport details, such as encryption or chunking, in order
9266 to work properly in certain situations. Now, the only difference
9267 between nph and non-nph scripts is "non-parsed headers".
9268 [Dean Gaudet, Sameer Parekh, Roy Fielding]
9270 *) If a BUFF is switched from buffered to unbuffered reading the first
9271 bread() will return whatever remained in the buffer prior to the
9272 switch. [Dean Gaudet]
9274 Changes with Apache 1.3a1
9276 *) Added another Configure helper script: TestLib. It determines
9277 if a specified library exists. [Jim Jagielski]
9279 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
9280 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
9283 *) PORT: Some architectures use size_t for various lengths in network
9284 functions such as accept(), and getsockname(). The definition
9285 NET_SIZE_T is used to control this. [Dean Gaudet]
9287 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
9288 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
9289 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
9291 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
9292 [Igor N Kovalenko <infoh@mail.wplus.net>]
9294 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
9295 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
9296 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
9297 [Dean Gaudet] related PR#875
9299 *) API: Correct child_init() slot declaration from int to void, to
9300 match the init() declaration. Update mod_example to use the new
9303 *) added transport handle slot (t_handle) to the BUFF structure
9306 *) get_client_block() returns wrong length if policy is
9307 REQUEST_CHUNKED_DECHUNK.
9308 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
9310 *) Support the image map format of FrontPage. For example:
9311 rect /url.hrm 10 20 30 40
9312 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
9314 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
9315 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
9317 *) AddModuleInfo directive for mod_info which allows you to annotate
9318 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9320 *) Added NoProxy directive to avoid using ProxyRemote for selected
9321 addresses. Added ProxyDomain directive to cause unqualified
9322 names to be qualified by redirection.
9323 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
9325 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
9326 header to the remote host in the proxy. [Sameer Parekh and
9329 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
9330 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
9331 URLs, fixed rewritelog(), fixed forced response code handling on
9332 redirects from within .htaccess files, disabled pipe locking under
9333 braindead SunOS 4.1.x, allow env variables to be set even on rules with
9334 no substitution, bugfixed situations where HostnameLookups is off, made
9335 mod_rewrite more thread-safe for NT port and fixed problem when creating
9336 an empty query string via "xxx?".
9337 This update also removes the copyright of Ralf S. Engelschall,
9338 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
9339 exclusively copyrighted by the Apache Group now. This happened because
9340 the author now has gifted mod_rewrite exclusively to the Apache Group and
9341 no longer maintains an external version.
9342 [Ralf S. Engelschall]
9344 *) API: Added child_init function to module structure. This is called
9345 once per "heavy-weight process" before any requests are handled.
9346 See http_config.h for more details. [Dean Gaudet]
9348 *) Anonymous_LogEmail was logging on each subrequest.
9349 [Dean Gaudet] PR#421, 868
9351 *) API: Added is_initial_req() which tests if the request being
9352 processed is the initial request, or a subrequest.
9355 *) Extended SSI (mod_include) now handles additional relops for
9356 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
9358 *) Configure fixed to correctly propagate user-selected options and
9359 settings (such as CC and OPTIM) to Makefiles other than
9360 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
9362 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
9363 directory indices to start with the contents of the HeaderName file
9364 if there is one. If there isn't one, the behaviour is unchanged.
9365 [Ken Coar, Roy Fielding, Andrey A. Chernov]
9367 *) WIN32: Modules can now be dynamically loaded DLLs using the
9368 LoadModule/LoadFile directives. Note that module DLLs must be
9369 compiled with the multithreaded DLL version of the runtime library.
9370 [Alexei Kosut and Ben Laurie]
9372 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
9373 This allows the admin to completely remove automatic indexing
9374 from the server, while still supporting the basic functions of
9375 trailing-slash redirects and DirectoryIndex files. Note that if
9376 you're carrying over an old Configuration file and you use directory
9377 indexing then you'll want to add:
9379 Module autoindex_module mod_autoindex.o
9381 before mod_dir in your Configuration. [Dean Gaudet]
9383 *) popendir/pclosedir created to properly protect directory scanning.
9384 [Dean Gaudet] PR#525
9386 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
9387 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
9388 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
9391 *) The AccessFileName directive can now take more than one filename.
9392 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9394 *) The new mod_mime_magic can be used to "magically" determine the type
9395 of a file if the extension is unknown. Based on the unix file(1)
9396 command. [Ian Kluft <ikluft@cisco.com>]
9398 *) We now determine and display the time spent processing a
9399 request if desired. [Jim Jagielski]
9401 *) mod_status: PID field of "dead" child slots no longer displays
9402 main httpd process's PID. [Jim Jagielski]
9404 *) Makefile.nt added - to build all the bits from the command line:
9405 nmake -f Makefile.nt
9406 Doesn't yet work properly. [Ben Laurie]
9408 *) Default text of 404 error is now "Not Found" rather than the
9409 potentially misleading "File Not Found". [Ken Coar]
9411 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
9412 for the net if we require people that actually need this data to
9413 enable it. [Linus Torvalds]
9415 *) directory_walk() is an expensive function, keep a little more state to
9416 avoid needless string counting. Add two new functions make_dirstr_parent
9417 and make_dirstr_prefix which replace all existing uses of make_dirstr.
9418 The new functions are a little less general than make_dirstr, but
9419 work more efficiently (less memory, less string counting).
9422 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
9423 to LDFLAGS) to avoid complications with lex rules in make files.
9424 [Dean Gaudet] PR#372
9426 *) run_method optimized to avoid needless scanning over NULLs in the
9427 module list. [Dean Gaudet]
9429 *) Revamp of (unix) scoreboard management code such that it avoids
9430 unnecessary traversals of the scoreboard on each hit. This is
9431 particularly important for high volume sites with a large
9432 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
9433 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
9434 httpd.h. [Dean Gaudet]
9436 *) In configurations using multiple Listen statements it was possible for
9437 busy sockets to starve other sockets of service. [Dean Gaudet]
9439 *) Added hook so standalone_main can be replaced at compile time
9440 (define STANDALONE_MAIN)
9443 *) Lowest-level read/write functions in buff.c will be replaced with
9444 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
9445 compile time. The default sfio discipline will behave as apache
9446 would without sfio compiled in.
9449 *) Enhance UserDir directive (mod_userdir) to accept a list of
9450 usernames for the 'disable' keyword, and add 'enable user...' to
9451 selectively *en*able userdirs if they're globally disabled.
9454 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
9455 will work with Netscape dbm files. (dbmmanage will probably not
9456 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
9458 *) Add a ListenBacklog directive to control the backlog parameter
9459 passed to listen(). Also change the default to 511 from 512.
9462 *) API: A new handler response DONE which informs apache that the
9463 request has been handled and it can finish off quickly, similar to
9464 how it handles errors. [Rob Hartill]
9466 *) Turn off chunked encoding after sending terminating chunk/footer
9467 so that we can't do it twice by accident. [Roy Fielding]
9469 *) mod_expire also issues Cache-Control: max-age headers.
9472 *) API: Added kill_only_once option for free_proc_chain so that it won't
9473 aggressively try to kill off specific children. For fastcgi.
9474 [Stanley Gambarin <gambarin@OpenMarket.com>]
9476 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
9478 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
9479 When used together, these cause mod_dir to emit HEIGHT and WIDTH
9480 attributes in the FancyIndexing IMG tags. [Ken Coar]
9482 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
9484 *) PORT: Added Windows NT support
9485 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
9487 Changes with Apache 1.2.6
9489 *) mod_include when using XBitHack Full would send ETags in addition to
9490 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
9491 [Dean Gaudet] PR#1133
9493 *) SECURITY: When a client connects to a particular port/addr, and
9494 gives a Host: header ensure that the virtual host requested can
9495 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
9497 *) Support virtual hosts with wildcard port and/or multiple ports
9498 properly. [Ed Korthof <ed@organic.com>]
9500 *) Fixed some case-sensitivity issues according to RFC2068.
9503 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
9504 and mod_include.c. [Dean Gaudet]
9506 *) Variable 'cwd' was being used pointlessly before being set.
9509 *) SIGURG doesn't exist on all platforms.
9510 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
9512 *) When an error occurs during a POST, or other operation with a
9513 request body, the body has to be read from the net before allowing
9514 a keepalive session to continue. [Roy Fielding] PR#1399
9516 *) When an error occurs in fcntl() locking suggest the user look up
9517 the docs for LockFile. [Dean Gaudet]
9519 *) table_set() and table_unset() did not deal correctly with
9520 multiple occurrences of the same key. [Stephen Scheck
9521 <sscheck@infonex.net>, Ben Laurie] PR#1604
9523 *) send_fd_length() did not calculate total_bytes_sent properly in error
9524 cases. [Ben Reser <breser@regnow.com>] PR#1366
9526 *) r->connection->user was allocated in the wrong pool causing corruption
9527 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
9529 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9530 Also removed the auto-generated link to www.apache.org that was the
9531 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
9533 *) Multiple "close" tokens may have been set in the "Connection"
9534 header, not an error, but a waste.
9535 [Ronald.Tschalaer@psi.ch] PR#1683
9537 *) "basic" and "digest" auth tokens should be tested case-insensitive.
9538 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
9540 *) It appears the "257th byte" bug (see
9541 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
9542 at the 256th byte as well. Fixed. [Dean Gaudet]
9544 *) mod_rewrite would not handle %3f properly in some situations.
9547 *) Apache could generate improperly chunked HTTP/1.1 responses when
9548 the bputc() or rputc() functions were used by modules (such as
9549 mod_include). [Dean Gaudet]
9551 *) #ifdef wrap a few #defines in httpd.h to make life easier on
9552 some ports. [Ralf Engelschall]
9554 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
9556 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
9558 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
9560 Changes with Apache 1.2.5
9562 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
9563 only an issue on systems without a MAXDNAME define or where
9564 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
9566 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
9569 *) Fix core dump in the ftp proxy when reading incorrectly formatted
9570 directory listings. [Marc Slemko]
9572 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
9575 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
9576 is used to read various types of files such as htaccess and
9577 htpasswd files. [Marc Slemko]
9579 *) SECURITY: Ensure that the buffer returned by ht_time is always
9580 properly null terminated. [Marc Slemko]
9582 *) SECURITY: General mod_include cleanup, including fixing several
9583 possible buffer overflows and a possible infinite loop. This cleanup
9584 was done against 1.3 code and then backported to 1.2, the result
9585 is a large difference (due to indentation cleanup in 1.3 code).
9586 Users interested in seeing a smaller set of relevant differences
9587 should consider comparing against src/modules/standard/mod_include.c
9588 from the 1.3b3 release. Non-indentation changes to mod_include
9589 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
9591 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9592 including fixing a possible buffer overflow. This cleanup also
9593 was done with 1.3 code as a basis, see the the previous note
9594 about mod_include. [Dean Gaudet]
9596 *) SECURITY: If a htaccess file can not be read due to bad
9597 permissions, deny access to the directory with a HTTP_FORBIDDEN.
9598 The previous behavior was to ignore the htaccess file if it could not
9599 be read. This change may make some setups with unreadable
9600 htaccess files stop working. PR#817 [Marc Slemko]
9602 *) SECURITY: no2slash() was O(n^2) in the length of the input.
9603 Make it O(n). This inefficiency could be used to mount a denial
9604 of service attack against the Apache server. Thanks to
9605 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
9608 *) mod_include used uninitialized data for some uses of && and ||.

9611 *) mod_imap should decline all non-GET methods.
9612 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
9614 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
9616 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
9617 r->filename. Since those two are meant to be in sync with each other
9618 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
9620 *) mod_include did not properly handle all possible redirects from sub-
9621 requests. [Ken Coar]
9623 *) Inetd mode (which is buggy) uses timeouts without having setup the
9624 jmpbuffer. [Dean Gaudet] PR#1064
9626 *) Work around problem under Linux where a child will start looping
9627 reporting a select error over and over.
9628 [Rick Franchuk <rickf@transpect.net>] PR#1107
9630 Changes with Apache 1.2.4
9632 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
9633 always making requests with the full-URI instead of just the URI path.
9634 [Marc Slemko, Roy Fielding]
9636 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
9637 on this platform. [Marc Slemko]
9639 Changes with Apache 1.2.3
9641 *) The request to a remote proxy was mangled if it was generated as the
9642 result of a ProxyPass directive. URL schemes other than http:// were not
9643 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
9644 PR#812 [Lars Eilebrecht]
9646 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9647 information for case where proxy module is not available. [Marc Slemko]
9649 *) Force proxy to always respond as HTTP/1.0, which it was failing to
9650 do for errors and cached responses. [Roy Fielding]
9652 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
9654 Changes with Apache 1.2.2 [not released]
9656 *) Fixed another long-standing bug in sub_req_lookup_file where it would

9662 USE_FLOCK_SERIALIZED_ACCEPT is defined.
9665 *) Enhanced the chunking and error handling inside the buffer functions.
9666 [Dean Gaudet, Roy Fielding]
9668 *) When merging the main server's <Directory> and <Location> sections into
9669 a vhost, put the main server's first and the vhost's second. Otherwise
9670 the vhost can't override the main server. [Dean Gaudet] PR#717
9672 *) The <Directory> code would merge and re-merge the same section after
9673 a match was found, possibly causing problems with some modules.
9676 *) Fixed an infinite loop in mod_imap for references above the server root.
9677 [Dean Gaudet] PR#748
9679 *) mod_include cleanup showed that handle_else was being used to handle
9680 endif. It didn't cause problems, but it was cleaned up too.
9683 *) Last official synchronization of mod_rewrite with author version (because
9684 mod_rewrite is now directly developed by the author at the Apache Group):
9685 o added diff between mod_rewrite 3.0.6+ and 3.0.9
9686 minus WIN32/NT stuff, but plus copyright removement.
9688 - workaround for detecting infinite rewriting loops
9689 - fixed setting of env vars when "-" is used as subst string

9692 - kludge to disable locking on pipes under braindead SunOS
9693 - fix for rewritelog in cases where remote hostname is unknown
9694 - fixed totally damaged request_rec walk-back loop
9695 o remove static from local data and add static to global ones.
9696 o replaced ugly proxy finding stuff by simple

9709 a deficiency in the header_parse phase.

9730 *) API: In HTTP/1.1, whether or not a request message contains a body
9731 is independent of the request method and based solely on the presence
9732 of a Content-Length or Transfer-Encoding. Therefore, our default
9733 handlers need to be prepared to read a body even if they don't know
9734 what to do with it; otherwise, the body would be mistaken for the
9735 next request on a persistent connection. discard_request_body()
9736 has been added to take care of that. [Roy Fielding] PR#378
9738 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
9739 release version number, such that it always increases along the
9740 same lines as our source code branching. [Roy Fielding]

9744 Changes with Apache 1.2.1

9752 could contain "../" allowing a local user to "publish" any file on
9753 the system. No slashes are allowed now. [Dean Gaudet]
9755 *) SECURITY: It was possible to violate the symlink Options using mod_dir
9756 (headers, readmes, titles), mod_negotiation (type maps), or
9757 mod_cern_meta (meta files). [Dean Gaudet]
9759 *) SECURITY: Apache will refuse to run as "User root" unless
9760 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
9762 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
9763 if it contained a .htaccess disallowing symlinks. This is contrary
9764 to the rule that symlink permissions are tested with the symlink
9765 options of the parent directory. [Dean Gaudet] PR#353
9767 *) CONFIG: The LockFile directive can be used to place the serializing
9768 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
9769 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
9772 *) Request processing now retains state of whether or not the request
9773 body has been read, so that internal redirects and subrequests will
9774 not try to read it twice (and block). [Roy Fielding]
9776 *) Add a placeholder in modules/Makefile to avoid errors with certain
9777 makes. [Marc Slemko]

9786 handle high numbered descriptors (examples include bind, and
9787 solaris libc). On all systems apache attempts to keep all permanent
9788 descriptors above 15 (called the low slack line). Solaris users
9789 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
9790 which keeps all non-FILE * descriptors above 255. On all systems
9791 this should make supporting large numbers of vhosts with many open
9792 log files more feasible. If this causes trouble please report it,
9793 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
9794 [Dean Gaudet] various PRs
9796 *) Related to the last entry, network sockets are now opened before
9797 log files are opened. The only known case where this can cause
9798 problems is under Solaris with many virtualhosts and many Listen
9799 directives. But using -DHIGH_SLACK_LINE=256 described above will
9800 work around this problem. [Dean Gaudet]

9855 reading from one buffer and writing to another, at least until it has
9856 a custom timeout handler. [Roy Fielding and Petr Lampa]

9866 *) Virtual hosts with the same ServerName, but on different ports, were
9867 not being selected properly. [Ed Korthof]

9872 [Chuck Murcko] PR#614
9874 *) If multiple requests on a single connection are used to retrieve

9895 *) Configure changes: Allow for whitespace at the start of a
9896 Module declaration. Also, be more understanding about the
9897 CC=/OPTIM= format in Configuration. Finally, fix compiler
9898 flags if using HP-UX's cc compiler. [Jim Jagielski]
9900 *) Subrequests and internal redirects now inherit the_request from the
9901 original request-line. [Roy Fielding]
9903 *) Test for error conditions before creating output header fields, since
9904 we don't want the error message to include those fields. Likewise,
9905 reset the content_language(s) and content_encoding of the response
9906 before generating or redirecting to an error message, since the new
9907 message will have its own Content-* definitions. [Dean Gaudet]
9909 *) Restored the semantics of headers_out (headers sent only with 200..299
9910 and 304 responses) and err_headers_out (headers sent with all responses).
9911 Avoid the overhead of copying tables if err_headers_out is empty
9912 (the usual case). [Roy Fielding]
9914 *) Fixed a couple places where a check for the default Content-Type was
9915 not properly checking both the value configured by the DefaultType
9916 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
9917 of DEFAULT_TYPE to match the documented default (text/plain).

9923 *) Properly initialize the flock structures used by the mutex locking
9924 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
9927 *) The method for determining PATH_INFO has been restored to the pre-1.2b
9928 (and NCSA httpd) definition wherein it was the extra path info beyond
9929 the CGI script filename. The environment variable FILEPATH_INFO has
9930 been removed, and instead we supply the original REQUEST_URI to any
9931 script that wants to be Apache-specific and needs the real URI path.
9932 This solves a problem with existing scripts that use extra path info
9933 in the ScriptAlias directive to pass options to the CGI script.
9936 *) The _default_ change in 1.2b10 will change the behaviour on configs
9937 that use multiple Listen statements for listening on multiple ports.
9938 But that change is necessary to make _default_ consistent with other
9939 forms of <VirtualHost>. It requires such configs to be modified
9940 to use <VirtualHost _default_:*>. The documentation has been
9941 updated. [Dean Gaudet] PR#530
9943 *) If an ErrorDocument CGI script is used to respond to an error
9944 generated by another CGI script which has already read the message
9945 body of the request, the server would block trying to read the
9946 message body again. [Rob Hartill]

9949 other platforms). Fixed. [Ben Laurie] PR#512

9967 Changes with Apache 1.2b9 [never announced]
9969 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
9970 changes and in anticipation of 1.2 final release. [Roy Fielding]
9972 *) Fix problem with scripts not receiving a SIGPIPE when client drops
9973 the connection (e.g., when user presses Stop). Apache will now stop
9974 trying to send a message body immediately after an error from write.
9975 [Roy Fielding and Nathan Kurz] PR#335
9977 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
9978 than mod_alias, and mod_alias has higher priority than mod_proxy;
9979 rearranged other modules to enhance understanding of their purpose
9980 and relative order (and maybe even reduce some overhead).

9983 *) Fix graceful restart. Eliminate many signal-related race
9984 conditions in both forms of restart, and in SIGTERM. See
9985 htdocs/manual/stopping.html for details on stopping and
9986 restarting the parent. [Dean Gaudet]
9988 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
9989 memory allocator to avoid a behaviour that required extra blocks to
9990 be allocated. [Dean Gaudet]
9992 *) Allow suexec to access files relative to current directory but not
9993 above. (Excluding leading / or any .. directory.) [Ken Coar]
9996 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]

10001 area so that it won't be overwritten by the call to getgrgid(), and
10002 fix some misuse of the pool string allocation functions. Also fixes
10003 a general problem with parsing URL query info into args for CGI scripts.

10016 object that can't be PUT, or FOOBAR for some method FOOBAR that
10017 apache doesn't know about at all). Log 404s that occur in mod_include.
10018 [Paul Sutton, John Van Essen]
10020 *) If a soft timeout (or lingerout) occurs while trying to flush a
10021 buffer or write inside buff.c or fread'ing from a CGI's output,
10022 then the timeout would be ignored. [Roy Fielding] PR#373
10024 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
10025 parsing of headers. If the terminating empty-line CRLF occurs starting
10026 at the 256th or 257th byte of output, then Navigator will think a normal
10027 image is invalid. We are guessing that this is because their initial
10028 read of a new request uses a 256 byte buffer. We check the bytes written
10029 so far and, if we are about to tickle the bug, we instead insert a
10030 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
10032 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
10033 of an external redirection. [Roy Fielding and Paul Sutton]

10036 contained a commented-out Rule. [Roy Fielding]
10038 *) Promote per_dir_config and subprocess_env from the subrequest to the
10039 main request in mod_negotiation. In particular this fixes a bug
10040 where <Files> sections wouldn't properly apply to negotiated content.

10052 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
10054 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
10055 1.x the settings are those of pre-1.2b8. For 2.x we include
10056 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
10057 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
10058 [Dean Gaudet] PR#336, PR#340

10076 *) For hosts with multiple IP addresses, try all additional addresses if
10077 necessary to get a connect. Fail only if hostent address list is
10078 exhausted. [Chuck Murcko]
10080 *) More signed/unsigned port fixes. [Dean Gaudet]
10082 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
10085 Changes with Apache 1.2b8
10087 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
10088 to it. [Marc Slemko]
10090 *) The addition of <Location> and <File> directives made the
10091 sub_req_lookup_simple() function bogus, so we now handle
10092 the special cases directly. [Dean Gaudet]
10094 *) We now try to log where the server is dumping core when a fatal
10095 signal is received. [Ken Coar]
10097 *) Improved lingering_close by adding a special timeout, removing the
10098 spurious log messages, removing the nonblocking settings (they
10099 are not needed with the better timeout), and adding commentary
10100 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
10101 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]

10104 log instead of stderr. [Roy Fielding]
10106 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
10108 *) Stopgap solution for CGI 3-second delay with server-side includes: if
10109 processing a subrequest, allocate memory from r->main->pool instead
10110 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
10111 in the middle of an SSI request. [Dean Gaudet] PR #122
10113 *) Fixed status of response when POST is received for a nonexistent URL
10114 (was sending 405, now 404) and when any method is sent with a
10115 full-URI that doesn't match the server and the server is not acting
10116 as a proxy (was sending 501, now 403). [Roy Fielding]
10118 *) Host port changed to unsigned short. [Ken Coar] PR #276
10120 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
10122 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
10124 *) Report extra info from errno with many errors that cause httpd to exit.
10125 spawn_child, popenf, and pclosef now have valid errno returns in the
10126 event of an error. Correct problems where errno was stomped on
10127 before being reported. [Dean Gaudet]
10129 *) In the proxy, if the cache filesystem was full, garbage_coll() was
10130 never called, and thus the filesystem would remain full indefinitely.
10131 We now also remove incomplete cache files left if the origin server
10132 didn't send a Content-Length header and either the client has aborted
10133 transfer or bwrite() to client has failed. [Petr Lampa]
10135 *) Fixed the handling of module and script-added header fields.
10136 Improved the interface for sending header fields and reduced
10137 the duplication of code between sending okay responses and errors.
10138 We now always send both headers_out and err_headers_out, and
10139 ensure that the server-reserved fields are not being overridden,
10140 while not overriding those that are not reserved. [Roy Fielding]
10142 *) Moved transparent content negotiation fields to err_headers_out
10143 to reflect above changes. [Petr Lampa]
10145 *) Fixed the determination of whether or not we should make the
10146 connection persistent for all of the cases where some other part
10147 of the server has already indicated that we should not. Also
10148 improved the ordering of the test so that chunked encoding will
10149 be set whenever it is desired instead of only when KeepAlive
10150 is enabled. Added persistent connection capability for most error
10151 responses (those that do not indicate a bad input stream) when
10152 accessed by an HTTP/1.1 client. [Roy Fielding]
10154 *) Added missing timeouts for sending header fields, error responses,
10155 and the last chunk of chunked encoding, each of which could have
10156 resulted in a process being stuck in write forever. Using soft_timeout
10157 requires that the sender check for an aborted connection rather than
10158 continuing after an EINTR. Timeouts that used to be initiated before
10159 send_http_header (and never killed) are now initiated only within or
10160 around the routines that actually do the sending, and not allowed to
10161 propagate above the caller. [Roy Fielding]
10163 *) mod_auth_anon required an @ or a . in the email address, not both.
10166 *) per_dir_defaults weren't set correctly until directory_walk for
10167 name-based vhosts. This fixes an obscure bug with the wrong config
10168 info being used for vhosts that share the same ip as the server.
10171 *) Improved generation of modules/Makefile to be more generic for
10172 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
10174 *) Generate makefile dependency for Configuration based on the actual
10175 name given when running the Configure process. [Dean Gaudet]
10177 *) Fixed problem with vhost error log not being set prior to
10178 initializing virtual hosts. [Dean Gaudet]
10180 *) Fixed infinite loop when a trailing slash is included after a type map
10181 file URL (extra path info). [Petr Lampa]
10183 *) Fixed server status updating of per-connection counters. [Roy Fielding]
10185 *) Add documentation for DNS issues (reliability and security), and try
10186 to explain the virtual host matching process. [Dean Gaudet]
10188 *) Try to continue gracefully by disabling the vhost if a DNS lookup
10189 fails while parsing the configuration file. [Dean Gaudet]
10191 *) Improved calls to setsockopt. [Roy Fielding]
10193 *) Negotiation changes: Don't output empty content-type in variant list;
10194 Output charset in variant list; Return sooner from handle_multi() if
10195 no variants found; Add handling of '*' wildcard in Accept-Charset.
10196 [Petr Lampa and Paul Sutton]
10198 *) Fixed overlaying of request/sub-request notes and headers in
10199 mod_negotiation. [Dean Gaudet]
10201 *) If two variants' charset quality are equal and one is the default
10202 charset (iso-8859-1), then prefer the variant that was specifically
10203 listed in Accept-Charset instead of the default. [Petr Lampa]
10205 *) Memory allocation problem in push_array() -- it would corrupt memory
10206 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
10208 *) invoke_handler() doesn't handle mime arguments in content-type
10209 [Petr Lampa] PR#160
10211 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
10214 *) Fixed problem with ErrorDocument not working for virtual hosts
10215 due to one of the performance changes in 1.2b7. [Dean Gaudet]
10217 *) Log an error message if we get a request header that is too long,
10218 since it may indicate a buffer overflow attack. [Marc Slemko]
10220 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
10221 not reject URLs without a double-slash, as per RFC2068 section 3.2.
10222 [Ken Coar] PR #146, #187
10224 *) Added table entry placeholder for new header_parser callback
10225 in all of the distributed modules. [Ken Coar] PR #191
10227 *) Allow for cgi files without the .EXE extension on them under OS/2.
10228 [Garey Smiley] PR #59
10230 *) Fixed error message when resource is not found and URL contains
10231 path info. [Petr Lampa and Dean Gaudet] PR #40
10233 *) Fixed user and server confusion over what should be a virtual host
10234 and what is the main server, resulting in access to something
10235 other than the name defined in the virtualhost directive (but
10236 with the same IP address) failing. [Dean Gaudet]
10238 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
10239 AIX; improves the redirection stuff to enable the users to generally
10240 redirect to http, https, gopher and ftp; added TIME variable for
10241 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
10242 special patterns >STRING, <STRING and =STRING to RewriteCond, which
10243 can be used in conjunction with %{TIME} or other variables to create
10244 time-dependent rewriting rules. [Ralf S. Engelschall]
10246 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
10247 Module authors may need to adjust their code for proper cleanup to take
10248 place (that is, call note_cleanups_for_fd()). This change fixes problems
10249 with file descriptors being erroneously closed when the proxy module was
10250 in use. [Ben Laurie]
10252 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
10253 initgroups() to hose the group information needed for later
10254 comparisons. [Randy Terbush]
10256 *) Remove unnecessary call to va_end() in create_argv() which
10257 caused a SEGV on some systems.
10259 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
10262 *) Clear memory allocated for listeners. [Randy Terbush]
10264 *) Improved handling of IP address as a virtualhost address and
10265 introduced "_default_" as a synonym for the default vhost config.
10266 [Dean Gaudet] PR #212
10268 Changes with Apache 1.2b7
10270 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
10272 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
10274 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
10275 - replace protocol response numbers with symbols
10276 - save variant-list into main request notes
10277 - free allocated memory from subrequests
10278 - merge notes, headers_out and err_headers_out
10280 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
10281 "HTTP/#.# ###*" to be more lenient about what we accept.
10284 *) more proxy FTP bug fixes:
10285 - Changed send_dir() to remove user/passwd from displayed URL.
10286 - Changed login error messages to be more descriptive.
10287 - remove setting of SO_DEBUG socket option
10288 - Make ftp_getrc() more lenient about multiline responses,
10289 specifically, 230 responses which don't have continuation 230-
10290 on each line). These seem to be all NT FTP servers, and while
10291 perhaps questionable, they appear to be legal by RFC 959.
10292 - Add missing kill_timeout() after transfer to user completes.
10295 *) Fixed problem where a busy server could hang when restarting
10296 after being sent a SIGHUP due to child processes not exiting.
10299 *) Modify mod_include escaping so a '\' only signifies an escaped
10300 character if the next character is one that needs
10301 escaping. [Ben Laurie]
10303 *) Eliminated possible infinite loop in mod_imap when relative URLs are
10304 used with a 'base' directive that does not have a '/' in it.
10305 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
10307 *) Reduced the default timeout from 1200 seconds to 300, and the
10308 one in the sample configfile from 400 to 300. [Marc Slemko]
10310 *) Stop vbprintf from crashing if given a NULL string pointer;
10311 print (null) instead. [Ken Coar]
10313 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
10314 [Marc Slemko and Roy Fielding]
10316 *) Fixed problem with mod_cgi-generated internal redirects trying to
10317 read the request message-body twice. [Archie Cobbs and Roy Fielding]
10319 *) Reduced timeout on lingering close, removed possibility of a blocked
10320 read causing the child to hang, and stopped logging of errors if
10321 the socket is not connected (reset by client). [Roy Fielding]
10323 *) Rearranged main child loop to remove duplication of code in
10324 select/accept and keep-alive requests, fixed several bugs regarding
10325 checking scoreboard_image for exit indication and failure to
10326 account for all success conditions and trap all error conditions,
10327 prevented multiple flushes before closing the socket; close the entire
10328 socket buffer instead of just one descriptor, prevent logging of
10329 EPROTO and ECONNABORTED on platforms where supported, and generally
10330 improved readability. [Roy Fielding]
10332 *) Extensive performance improvements. Cleaned up inefficient use of
10333 auto initializers, multiple is_matchexp calls on a static string,
10334 and excessive merging of response_code_strings. [Dean Gaudet]
10336 *) Added double-buffering to mod_include to improve performance on
10337 server-side includes. [Marc Slemko]
10339 *) Several fixes for suexec wrapper. [Randy Terbush]
10340 - Make wrapper work for files on NFS filesystem.
10341 - Fix portability problem of MAXPATHLEN.
10342 - Fix array overrun problem in clean_env().
10343 - Fix allocation of PATH environment variable
10345 *) Removed extraneous blank line is description of mod_status chars.
10348 *) Logging of errors from the call_exec routine simply went nowhere,
10349 since the logfile fd has been closed, so now we send them to stderr.
10350 [Harald T. Alvestrand]
10352 *) Fixed core dump when DocumentRoot is a CGI.
10353 [Ben Laurie, reported by geddis@tesserae.com]
10355 *) Fixed potential file descriptor leak in mod_asis; updated it and
10356 http_core to use pfopen/pfclose instead of fopen/fclose.
10357 [Randy Terbush and Roy Fielding]
10359 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
10360 as the DEC Alpha which is 64-bit but uses 32-bit ints.
10361 [Dean Gaudet and Ken Coar]
10363 *) Return a 302 response code to the client when sending a redirect
10364 due to a missing trailing '/' on a directory instead of a 301; now
10365 it is cacheable. [Markus Gyger]
10367 *) Fix condition where, if a bad directive occurs in .htaccess, and
10368 sub_request() goes first to this directory, then log_reason() will
10369 SIGSEGV because it doesn't have initialized r->per_dir_config.
10370 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
10372 *) Fix handling of lang_index in is_variant_better(). This was
10373 causing problems which resulted in the server sending the
10374 wrong language document in some cases. [Petr Lampa]
10376 *) Remove free() from clean_env() in suexec wrapper. This was nuking
10377 the clean environment on some systems.
10379 *) Tweak byteserving code (e.g. serving PDF files) to work around
10380 bugs in Netscape Navigator and Microsoft Internet Explorer.
10381 Emit Content-Length header when sending multipart/byteranges.
10384 *) Port to HI-UX/WE2. [Nick Maclaren]
10386 *) Port to HP MPE operating system for HP 3000 machines
10387 [Mark Bixby <markb@cccd.edu>]
10389 *) Fixed bug which caused a segmentation fault if only one argument
10390 given to RLimit* directives. [Ed Korthof]
10392 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
10394 *) Improved buffered output to the client by delaying the flush decision
10395 until the BUFF code is actually about to read the next request.
10396 This fixes a problem introduced in 1.2b5 with clients that send
10397 an extra CRLF after a POST request. Also improved chunked output
10398 performance by combining writes using writev() and removing as
10399 many bflush() calls as possible. NOTE: Platforms without writev()
10400 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
10401 or Configure, unless we have already done so. [Dean Gaudet]
10403 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
10405 *) Fixed mod_info output corruption bug introduced by buffer overflow
10406 fixes. [Dean Gaudet]
10408 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
10409 for the special case of a 304 response. [Paul Sutton]
10411 *) Improved handling of TRACE method by bypassing normal method handling
10412 and header parsing routines; fixed Allow response to always allow TRACE.
10415 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
10417 *) Cleaned-up some of the generated HTML. [Ken Coar]
10419 Changes with Apache 1.2b6
10421 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
10423 *) Fix typo introduced in fix for potential infinite loop around
10424 accept() in child_main(). This change caused the rev to 1.2b6.
10425 1.2b5 was never a public beta.
10427 Changes with Apache 1.2b5
10429 *) Change KeepAlive semantics (On|Off instead of a number), add
10430 MaxKeepAliveRequests directive. [Alexei Kosut]
10432 *) Various NeXT compilation patches, as well as a change in
10433 regex/regcomp.c since that file also used a NEXT define.
10436 *) Allow * to terminate the end of a directory match in mod_dir.
10437 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
10439 *) Don't call can_exec() if suexec_enabled. Calling this requires
10440 scripts executed by the suexec wrapper to be world executable, which
10441 defeats one of the advantages of running the wrapper. [Randy Terbush]
10443 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
10446 *) Migration from sprintf() to snprintf() to avoid buffer
10447 overflows. [Marc Slemko]
10449 *) Provide portable snprintf() implementation (ap_snprintf)
10450 as well as *cvt family. [Jim Jagielski]
10452 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
10455 *) Remove mod_fastcgi.c from the distribution. This module appears
10456 to be maintained more through the Open Market channels and should
10457 continue to be easily available at http://www.fastcgi.com/
10459 *) Fixed bug in modules/Makefile that wouldn't allow building in more
10460 than one subdirectory (or cleaning, either). [Jeremy Laidman]
10462 *) mod_info assumed that the config files were relative to ServerRoot.
10465 *) CGI scripts called as an error document resulting from failed
10466 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
10468 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
10471 *) Properly check errno to prevent display of a directory index
10472 when server receives a long enough URL to confuse stat().
10475 *) Several security enhancements to suexec wrapper. It is _highly_
10476 recommended that previously installed versions of the wrapper
10477 be replaced with this version. [Randy Terbush, Jason Dour]
10479 - ~user execution now properly restricted to ~user's home
10480 directory and below.
10481 - execution restricted to UID/GID > 100
10482 - restrict passed environment to known variables
10483 - call setgid() before initgroups() (portability fix)
10484 - remove use of setenv() (portability fix)
10486 *) Add HTTP/1.0 response forcing. [Ben Laurie]
10488 *) Add access control via environment variables. [Ben Laurie]
10490 *) Add rflush() function. [Alexei Kosut]
10492 *) remove duplicate pcalloc() call in new_connection().
10494 *) Fix incorrect comparison which could allow number of children =
10495 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
10496 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
10498 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
10499 AIX PS/2, CONVEXOS. [Jim Jagielski]
10501 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
10502 It's more portable. [Martin Kraemer]
10504 *) Replace references to make in Makefile.tmpl with $(MAKE).
10507 *) Add ProxyBlock directive w/IP address caching. Add IP address
10508 caching to NoCache directive as well. ProxyBlock works with all
10509 handlers; NoCache now also works with FTP for anonymous logins.
10510 Still more code cleanup. [Chuck Murcko]
10512 *) Add "header parse" API hook [Ben Laurie]
10514 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
10516 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
10518 *) Correctly allow access and auth directives in <Files> sections in
10519 server config files. [Alexei Kosut]
10521 *) Fix bug with ServerPath that could cause certain files to be not
10522 found by the server. [Alexei Kosut]
10524 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
10525 double-quote from text and so that it properly checks for unsupported
10526 status codes using the new index_of_response interface. [Roy Fielding]
10528 *) Multiple fixes to the lingering_close code in order to avoid being
10529 interrupted by a stray timeout, to avoid lingering on a connection
10530 that has already been aborted or never really existed, to ensure that
10531 we stop lingering as soon as any error condition is received, and to
10532 prevent being stuck indefinitely if the read blocks. Also improves
10533 reporting of error conditions. [Marc Slemko and Roy Fielding]
10535 *) Fixed initialization of parameter structure for sigaction.
10536 [mgyger@itr.ch, Adrian Filipi-Martin]
10538 *) Fixed reinitializing the parameters before each call to accept and
10539 select, and removed potential for infinite loop in accept.
10540 [Roy Fielding, after useful PR from adrian@virginia.edu]
10542 *) Fixed condition where, if a child fails to fork, the scoreboard would
10543 continue to say SERVER_STARTING forever. Eventually, the main process
10544 would refuse to start new children because count_idle_servers() will
10545 count those SERVER_STARTING entries and will always report that there
10546 are enough idle servers. [Phillip Vandry]
10548 *) Fixed bug in bcwrite regarding failure to account for partial writes.
10549 Avoided calling bflush() when the client is pipelining requests.
10550 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
10552 *) Added description of "." mode in server-status [Jim Jagielski]
10554 Changes with Apache 1.2b4
10556 *) Fix possible race condition in accept_mutex_init() that
10557 could leave a small security hole open allowing files to be
10558 overwritten in cases where the server UID has write permissions.
10561 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
10563 *) Fix portablity problem in util_script where ARG_MAX may not be
10564 defined for some systems.
10566 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
10569 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
10570 style magic #! token for better script portability. [Garey Smiley]
10572 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
10573 execution for ~userdir CGI. [Jason Dour]
10575 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
10577 *) Fix month off by one in suexec wrapper logging.
10579 Changes with Apache 1.2b3:
10581 *) Fix error in mod_cgi which could cause resources not to be properly
10582 freed, or worse. [Dean Gaudet]
10584 *) Fix find_string() NULL pointer dereference. [Howard Fear]
10586 *) Add set_flag_slot() at the request of Dirk and others.
10589 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
10591 *) Add changes to improve the error message given for invalid
10592 ServerName parameters. [Dirk vanGulik]
10594 *) Add "Authoritative" directive for Auth modules that don't
10595 currently have it. This gives admin control to assign authoritative
10596 control to an authentication scheme and allow "fall through" for
10597 those authentication modules that aren't "Authoritative" thereby
10598 allowing multiple authentication mechanisms to be chained.
10601 *) Remove requirement for ResourceConfig/AccessConfig if not using
10602 the three config file layout. [Randy Terbush]
10604 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
10606 *) Changes to suexec wrapper to fix the following problems:
10607 1. symlinked homedirs will kill ~userdirs.
10608 2. initgroups() on Linux 2.0.x clobbers gr->grid.
10609 3. CGI command lines paramters problems
10610 4. pw-pwdir for "docroot check" still the httpd user's pw record.
10611 [Randy Terbush, Jason Dour]
10613 *) Change create_argv() to accept variable arguments. This fixes
10614 a problem where arguments were not getting passed to the CGI via
10615 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
10617 *) Collapse multiple slashes in path URLs to properly apply
10618 handlers defined by <Location>. [Alexei Kosut]
10620 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
10622 *) Improve the accuracy of request duration timings by setting
10623 r->request_time in read_request_line() instead of read_request().
10626 *) Reset timeout while reading via get_client_block() in mod_cgi.c
10627 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
10629 *) Add the ability to pass different Makefile.tmpl files to Configure
10630 using the -make flag. [Rob Hartill]
10632 *) Fix coredump triggered when sending a SIGHUP to the server caused
10633 by an assertion failure, in turn caused by an uninitialised field in a
10637 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
10638 PATH_INFO from previous versions of Apache (in certain situations,
10639 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
10640 [later removed in 1.2b11]
10642 *) Add rwrite() function to API to allow for sending strings of
10643 arbitrary length. [Doug MacEachern]
10645 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
10647 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
10648 NeXT. [Jim Jagielski]
10650 *) Removed recent modification to promote the status code on internal
10651 redirects, since the correct fix was to change the default log format
10652 in mod_log_config so that it outputs the original status. [Rob Hartill]
10654 Changes with Apache 1.2b2:
10656 *) Update set_signals() to use sigaction() for setting handlers.
10657 This appears to fix a re-entrant problem in the seg_fault()
10658 bus_error() handlers. [Randy Terbush]
10660 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
10662 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
10664 *) proxy_http.c bugfixes: [Chuck Murcko]
10665 1) fixes possible NULL pointer reference w/NoCache
10666 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
10667 host would cache nothing if it was in the local domain,
10668 and the local domain was in the NoCache list)
10669 3) Adds Host: header when not available
10670 4) Some code cleanup and clarification
10672 *) mod_include.c bugfixes:
10673 1) Fixed an ommission that caused include variables to not
10674 be parsed in config errmsg directives [Howard Fear]
10675 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
10676 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
10677 4) Allow backslash-escaping to all quoted text
10678 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
10679 5) Pass variable to command line if not set in XSSI's env
10682 *) Fix infinite loop when processing Content-language lines in
10683 type-map files. [Alexei Kosut]
10685 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
10687 *) Fixed problem in set_[user|group] that prevented CGI execution
10688 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
10690 *) Added PORTING information file. [Jim Jagielski]
10692 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
10694 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
10696 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
10697 USE_FCNTL_SERIALIZED_ACCEPT was intended.
10699 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
10700 which caused problems of systems where socket s_addr is >32bits.
10702 *) Added comment to explain (r->chunked = 1) side-effect in
10703 http_protocol.c [Roy Fielding]
10705 *) Replaced use of index() in mod_expires.c with more appropriate
10706 and portable isdigit() test. [Ben Laurie]
10708 *) Updated Configure for ...
10709 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
10710 *-dg-dgux* (bad pattern match)
10711 QNX (DEF_WANTHSREGEX=yes)
10712 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
10714 *-unixware211 (new)
10715 and added some user diagnostic info. [Ben Laurie]
10717 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
10718 for better portability. [Jim Jagielski]
10720 *) Updated helpers/GuessOS for ...
10721 SCO 5 (recognize minor releases)
10722 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
10723 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
10724 IRIX64 (-sgi-irix64)
10725 ULTRIX (-unknown-ultrix)
10726 SINIX (-whatever-sysv4)
10727 NCR Unix (-ncr-sysv4)
10728 and fixed something in helpers/PrintPath [Ben Laurie]
10730 Changes with Apache 1.2b1
10732 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
10734 Changes with Apache 1.1.1

10737 logfile for each access [Mark Cox]
10739 *) Fixed bug where Redirect in .htaccess files would cause memory
10740 leak. [Nathan Neulinger]
10742 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
10744 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
10746 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
10748 Changes with Apache 1.1.0
10750 *) Bring NeXT support up to date. [Takaaki Matsumoto]
10752 *) Bring QNX support up to date. [Ben Laurie]
10754 *) Make virtual hosts default to main server keepalive parameters.
10755 [Alexei Kosut, Ben Laurie]
10757 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
10759 *) Fix missing address family for connect, also remove unreachable statement
10760 in mod_proxy. [Ben Laurie]
10762 *) mod_env now turned on by default in Configuration.tmpl.
10764 *) Bugs which were fixed:
10765 a) yet more mod_proxy bugs [Ben Laurie]
10766 b) CGI works again with inetd [Alexei Kosut]
10767 c) Leading colons were stripped from passwords [osm@interguide.com]
10768 d) Another fix to multi-method Limit problem [jk@tools.de]
10770 Changes with Apache 1.1b4
10772 *) r->bytes_sent variable restored. [Robert Thau]
10774 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
10776 *) More possibly unsecure programs removed from the support directory.
10778 *) More mod_auth_msql authentication improvements.
10780 *) VirtualHosts based on Host: headers no longer conflict with the
10783 *) OS/2 compatibility enhancements. [Gary Smiley]
10785 *) POST now allowed to directory index CGI scripts.
10787 *) Actions now work with files of the default type.
10789 *) Bugs which were fixed:
10790 a) more mod_proxy bugs
10791 b) early termination of inetd requests
10792 c) compile warnings on several systems
10793 d) problems when scripts stop reading output early
10795 Changes with Apache 1.1b3
10797 *) Much of cgi-bin and all of cgi-src has been removed, due to
10798 various security holes found and that we could no longer support
10801 *) The "Set-Cookie" header is now special-cased to not merge multiple
10802 instances, since certain popular browsers can not handle multiple
10803 Set-Cookie instructions in a single header. [Paul Sutton]
10805 *) rprintf() added to buffer code, occurrences of sprintf removed.
10808 *) CONNECT method for proxy module, which means tunneling SSL should work.
10809 (No crypto needed) Also a NoCache config directive.
10811 *) Several API additions: pstrndup(), table_unset() and get_token()
10812 functions now available to modules.
10814 *) mod_imap fixups, in particular Location: headers are now complete
10817 *) New "info" module which reports on installed module set through a
10818 special URL, a la mod_status.
10820 *) "ServerPath" directive added - allows for graceful transition
10821 for Host:-header-based virtual hosts.
10823 *) Anonymous authentication module improvements.
10825 *) MSQL authentication module improvements.
10827 *) Status module design improved - output now table-based. [Ben Laurie]
10829 *) htdigest utility included for use with digest authentication
10832 *) mod_negotiation: Accept values with wildcards to be treated with
10833 less priority than those without wildcards at the same quality
10834 value. [Alexei Kosut]
10836 *) Bugs which were fixed:
10837 a) numerous mod_proxy bugs
10838 b) CGI early-termination bug [Ben Laurie]
10839 c) Keepalives not working with virtual hosts
10840 d) RefererIgnore problems
10841 e) closing fd's twice in mod_include (causing core dumps on
10842 Linux and elsewhere).
10844 Changes with Apache 1.1b2
10847 a) core dumps in mod_digest
10848 b) truncated hostnames/ip address in the logs
10849 c) relative URL's in mod_imap map files
10851 Changes with Apache 1.1b1
10853 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
10855 Changes with Apache 1.0.3
10857 *) Internal redirects which occur in mod_dir.c now preserve the
10858 query portion of a request (the bit after the question mark).
10861 *) Escape active characters '<', '>' and '&' in html output in
10862 directory listings, error messages and redirection links.
10865 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
10867 *) Fix for POSIX compliance in waiting for processes in alloc.c.
10870 *) setsockopt no longer takes a const declared argument [Martijn Koster]
10872 *) Reset timeout timer after each successful fwrite() to the network.
10873 This patch adds a reset_timeout() procedure that is called by
10874 send_fd() to reset the timeout ever time data is written to the net.
10877 *) timeout() signal handler now checks for SIGPIPE and reports
10878 lost connections in a more user friendly way. [Rob Hartill]
10880 *) Location of the "scoreboard" file which used to live in /tmp is
10881 now configurable (for OSes that can't use mmap) via ScoreBoardFile
10882 which works similar to PidFile (in httpd.conf) [Rob Hartill]
10884 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
10886 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
10887 which caused a SEGV with cookies enabled
10889 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
10892 *) Log the UNIX textual error returned by some system calls, in
10893 particular errors from accept() [David Robinson]
10895 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
10897 Changes with Apache 1.0.2
10899 *) patch to get Apache compiled on UnixWare 2.x, recommended as
10900 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
10902 *) Fix get_basic_auth_pw() to set the auth_type of the request.
10905 *) past changes to http_config.c to only use the
10906 setrlimit function on systems defining RLIMIT_NOFILE
10907 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
10908 for SUNOS and prototypes the needed functions.
10910 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
10913 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
10915 *) Merge multiple headers from CGI scripts instead of taking last
10916 one. [David Robinson]
10918 *) Add support for SCO 5. [Ben Laurie]
10920 Changes with Apache 1.0.1
10922 *) Silence mod_log_referer and mod_log_agent if not configured
10925 *) Recursive includes can occur if the client supplies PATH_INFO data
10926 and the server provider uses relative links; as file.html
10927 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
10929 *) The replacement for initgroups() did not call {set,end}grent(). This
10930 had two implications: if anything else used getgrent(), then
10931 initgroups() would fail, and it was consuming a file descriptor.
10934 *) On heavily loaded servers it was possible for the scoreboard to get
10935 out of sync with reality, as a result of a race condition.
10936 The observed symptoms are far more Apaches running than should
10937 be, and heavy system loads, generally followed by catastrophic
10938 system failure. [Ben Laurie]
10940 *) Fix typo in license. [David Robinson]
10942 Changes with Apache 1.0.0 23 Nov 1995
10944 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
10946 Changes with Apache 0.8.16 05 Nov 1995
10948 *) New man page for 'httpd' added to support directory [David Robinson]
10950 *) .htgroup files can have more than one line giving members for a
10951 given group (each must have the group name in front), for NCSA
10952 back-compatibility [Robert Thau]
10954 *) Mutual exclusion around accept() is on by default for SVR4 systems
10955 generally, since they generally can't handle multiple processes in
10956 accept() on the same socket. This should cure flaky behavior on
10957 a lot of those systems. [David Robinson]
10959 *) AddType, AddEncoding, and AddLanguage directives take multiple
10960 extensions on a single command line [David Robinson]
10962 *) UserDir can be disabled for a given virtual host by saying
10963 "UserDir disabled" in the <VirtualHost> section --- it was a bug
10964 that this didn't work. [David Robinson]
10966 *) Compiles on QNX [Ben Laurie]
10968 *) Corrected parsing of ctime time format [David Robinson]
10970 *) httpd does a perror() before exiting if it can't log its pid
10971 to the PidFile, to make diagnosing the error a bit easier.
10974 *) <!--#include file="..."--> can no longer include files in the
10975 parent directory, for NCSA back-compatibility. [David Robinson]
10977 *) '~' is *not* escaped in URIs generated for directory listings
10980 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
10982 *) Fixed bug involving handling URIs with escaped %-characters
10983 in redirects [David Robinson]
10985 Changes with Apache 0.8.15 14 Oct 1995
10987 *) Switched to new, simpler license
10989 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
10991 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
10993 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
10995 *) Correctly handles internal redirects to files with names containing '%'
10998 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
11000 *) Use geteuid() rather than getuid() to see if we have root privilege,
11001 so that server correctly resets privilege if run setuid root. [Andrew
11004 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
11007 *) Fix relative URLs in imagemap files [Randy Terbush]
11009 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
11012 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
11013 entries all name the same one. [David Robinson]
11015 *) Fix directory listings with filenames containing unusual characters
11018 *) Better URI-escaping for generated URIs in directories with filenames
11019 containing unusual characters [Ben Laurie]
11021 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
11023 *) Unblock alarms on error return from spawn_child() [David Robinson]
11025 *) Sample Config files have extra note for SCO users [Ben Laurie]
11027 *) Configuration has note for HP-UX users [Rob Hartill]
11029 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
11031 *) Nuked bogus #define in httpd.h [David Robinson]
11033 *) Better test for whether a system has setrlimit() [David Robinson]
11035 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
11037 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
11040 Changes with Apache 0.8.14 19 Sep 1995
11042 *) Compiles on SCO ODT 3.0 [Ben Laurie]
11044 *) AddDescription works (better) [Ben Laurie]
11046 *) Leaves an intelligible error diagnostic when it can't set group
11047 privileges on standalone startup [Andrew Wilson]
11049 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
11050 that machine, which claims to be BSD but does not support RLIMIT.
11053 *) gcc -Wall no longer complains about an unused variable when util.c
11054 is compiled with -DMINIMAL_DNS [Andrew Wilson]
11056 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
11058 Changes with Apache 0.8.13 07 Sep 1995
11060 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
11062 *) Have built-in imagemap code recognize & honor Point directive [James
11065 *) Generate cleaner directory listings in directories with a mix of
11066 long and short filenames [Rob Hartill]
11068 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
11070 *) Properly default ServerName for virtual servers [Robert Thau]
11072 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
11073 Paul Richards and a cast of thousands...]
11075 *) On self-identified BSD systems (we don't try to guess any more),
11076 allocate a few extra file descriptors per virtual host with setrlimit,
11077 if we can, to avoid running out. [Randy Terbush]
11079 *) Write 22-character lock file name into buffer with enough space
11080 on startup [Konstantin Olchanski]
11082 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
11085 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
11087 *) Suppress -Wall warning by initializing variable in negotiation code
11088 [Tobias Weingartner]
11090 Changes with Apache 0.8.12 31 Aug 1995
11092 *) Doesn't pause three seconds after including a CGI script which is
11093 too slow to die off (this is done by not even trying to kill off
11094 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
11095 after the entire document has been processed). [Robert Thau]
11097 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
11099 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
11101 *) Allows .htaccess files to override <Directory> sections naming the
11102 same directory [David Robinson]
11104 *) Removed an efficiency hack in sub_req_lookup_uri which was
11105 causing certain extremely marginal cases (e.g., ScriptAlias of a
11106 *particular* index.html file) to fail. [David Robinson]
11108 *) Doesn't log an error when the requested URI requires
11109 authentication, but no auth header line was supplied by the
11110 client; this is a normal condition (the client doesn't no auth is
11111 needed here yet). [Robert Thau]
11113 *) Behaves more sanely when the name server loses its mind [Sean Welch]
11115 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
11117 *) RFC931 code no longer passes out name of prior clients on current
11118 requests if the current request came from a server that doesn't
11119 do RFC931. [David Robinson]
11121 *) Configuration script accepts "Module" lines with trailing whitespace.
11124 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
11126 *) Cleaned up comments in mod_cgi.c [Robert Thau]
11128 Changes with Apache 0.8.11 24 Aug 1995
11130 *) Wildcard <Directory> specifications work. [Robert Thau]
11132 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
11134 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
11135 the file being requested itself, in addition to the directories leading
11136 up to it. [Robert Thau]
11138 *) Logs access failures due to symlink checks or invalid client address
11139 in the error log [Roy Fielding, Robert Thau]
11141 *) Symlink checks deal correctly with systems where lstat of
11142 "/path/to/some/link/" follows the link. [Thau, Fielding]
11144 *) Doesn't reset DirectoryIndex to 'index.html' when
11145 other directory options are set in a .htaccess file. [Robert Thau]
11147 *) Clarified init code and nuked bogus warning in mod_access.c
11148 [Florent Guillaume]
11150 *) Corrected several directives in sample srm.conf
11151 --- includes corrections to directory indexing icon-related directives
11152 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
11153 icons for encodings right, and turning on AddEncoding by default).
11156 *) Corrected descriptions of args to AddIcon and AddAlt in command table
11159 *) INSTALL & README mention "contributed modules" directory [Brian
11162 *) Fixed English in the license language... "for for" --> "for".
11165 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
11166 mod_alias.c, merging it almost completely with handling of Alias, and
11167 adding a 'notes' field to the request_rec which allows the CGI module
11168 to discover whether the Alias module has put this request through
11169 ScriptAlias (which it needs to know for back-compatibility, as the old
11170 NCSA code did not check Options ExecCGI in ScriptAlias directories).
11173 Changes with Apache 0.8.10 18 Aug 1995
11175 *) AllowOverride applies to the named directory, and not just
11176 subdirectories. [David Robinson]
11178 *) Do locking for accept() exclusion (on systems that need it)
11179 using a special file created for the purpose in /usr/tmp, and
11180 not the error log; using the error log causes real problems
11181 if it's NFS-mounted; this is known to be the cause of a whole
11182 lot of "server hang" problems with Solaris. [David Robinson;
11183 thanks to Merten Schumann for help diagnosing the problem].
11185 Changes with Apache 0.8.9 12 Aug 1995
11187 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
11189 *) Nested includes see environment variables of the including document,
11190 for NCSA bug-compatibility (some sites have standard footer includes
11191 which try to print out the last-modified date). [Eric Hagberg/Robert
11194 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
11195 URI as a CGI script, even if it would have been treated as something
11196 else if requested directly, for NCSA back-compatibility. (Note that
11197 this means that people who know the name of the script can see the
11198 code just by asking for it). [Robert Thau]
11200 *) New version of dbmmanage script included in support directory as
11203 *) Check if scoreboard file couldn't be opened, and say so, rather
11204 then going insane [David Robinson]
11206 *) POST to CGI works on A/UX [Jim Jagielski]
11208 *) AddIcon and AddAlt commands work properly [Rob Hartill]
11210 *) NCSA server push works properly --- the Arena bug compatibility
11211 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
11212 if you still want the workaround). [Rob Hartill]
11214 *) If client didn't submit any Accept-encodings, ignore encodings in
11215 content negotiation. (NB this will all have to be reworked anyway
11216 for the new HTTP draft). [Florent Guillaume]
11218 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
11220 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
11222 *) Give Redirect priority over Alias, for NCSA bug compatibility
11225 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
11226 paralleling earlier bug fix for CGI [David Robinson]
11228 *) If DBM auth is improperly configured, report a server error and don't
11231 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
11232 it seems to work well enough without it (even in a 10 hits/sec
11233 workout), and the overhead for the locking under A/UX is
11234 alarmingly high (though it is very low on other systems).
11235 [Eric Hagberg, Jim Jagielski]
11237 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
11239 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
11240 Behlendorf/Eric Hagberg]
11242 *) More improvements to default Configuration for A/UX [Jim Jagielski]
11244 *) Compiles clean on NEXT [Rob Hartill]
11246 *) Compiles clean on SGI [Robert Thau]
11248 Changes with Apache 0.8.8 08 Aug 1995
11250 *) SunOS library prototypes now never included unless explicitly
11251 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
11252 people using GNU libc on SunOS are screwed by prototypes for the
11255 (Those who wish to compile clean with gcc -Wall on a standard
11256 SunOS setup need the prototypes, and may obtain them using
11257 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
11258 with nonstandard libraries are presumably competent to make their
11261 *) Strips trailing '/' characters off both args to the Alias command,
11262 to make 'Alias /foo/ /bar/' work.
11264 Changes with Apache 0.8.7 03 Aug 1995
11266 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
11267 [reported by David Robinson]
11269 *) Compiles clean on OSF/1 [David Robinson]
11271 *) Added some of the more recent significant changes (AddLanguage stuff,
11272 experimental LogFormat support) to CHANGES file in distribution root
11275 Changes with Apache 0.8.6 02 Aug 1995
11277 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
11278 (If you actually wanted a conditional GET which bypassed the cache, you
11279 couldn't get it). [Reported by Roy Fielding]
11281 *) Properly terminate headers on '304 Not Modified' replies to conditional
11282 GETs --- no browser we can find cares much, but the CERN proxy chokes.
11283 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
11285 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
11287 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
11288 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
11289 and older versions don't set the __SUNPRO_C preprocessor variable). On
11290 all other systems, these are never used anyway. [Reported by Mark Cox].
11292 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
11294 Changes with Apache 0.8.5 01 Aug 1995
11296 *) Added last-minute configurable log experiment, as optional module
11298 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
11299 properly. (One-line fix to http_protocol.c).
11301 *) Work around bogus behavior when reloading from Netscape.
11302 It's Netscape's bug --- for some reason they expect a request with
11303 If-modified-since: to not function as a conditional GET if it also
11304 comes with Pragma: no-cache, which is way out of line with the HTTP
11305 spec (according to Roy Fielding, the redactor).
11307 *) Added parameter to set maximum number of server processes.
11309 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
11312 *) IdentityCheck bugfix [Chuck Murcko].
11314 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
11316 *) More sample config file corrections; add extension to AddType for
11317 *.asis, move AddType generic description to its proper place, and
11318 fix miscellaneous typos. [ Alexei Kosut ]
11320 *) Deleted the *other* reference to the regents from the Berkeley
11321 legal disclaimer (everyplace).
11323 *) Nuked Shambhala name from src/README; had already cleaned it out
11324 of everywhere else.
11326 Changes with Apache 0.8.4
11328 *) Changes to server-pool management parms --- renamed current
11329 StartServers to MinSpareServers, created separate StartServers
11330 parameter which means what it says, and renamed MaxServers to
11331 MaxSpareServers (though the old name still works, for NCSA 1.4
11332 back-compatibility). The old names were generally regarded as
11333 too confusing. Also altered "docs" in sample config files.
11335 *) More improvements to default config files ---
11336 sample directives (commented out) for XBitHack, BindAddress,
11337 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
11338 defaults, AddTypes for send-as-is and imagemap magic types, and
11339 improvements to samples for DirectoryIndex [Alexei Kosut]
11341 *) Yet more improvements to default config files --- changes to
11342 Alexei's sample AddLanguage directives, and sample LanguagePriority
11343 [ Florent Guillaume ]
11345 *) Set config file locations properly if not set in httpd.conf
11348 *) Don't escape URIs in internal redirects multiple times; don't
11349 do that when translating PATH_INFO to PATH_TRANSLATED either.
11352 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
11354 Changes with Apache 0.8.3
11356 *) Edited distribution README to *briefly* summarize installation
11357 procedures, and give a pointer to the INSTALL file in the src/
11360 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
11361 recent NCSA distributions.
11363 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
11364 exist for the same directory, use both and don't segfault. [Reported
11367 *) Proper makefile dependencies [David Robinson]
11369 *) Note (re)starts in error log --- reported by Rob Hartill.
11371 *) Only call no2slash() after get_path_info() has been done, to
11372 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
11373 reported by Andrew Wilson, though this one is probably a real bug]
11375 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
11376 dump core when Referer is not supplied. [Randy Terbush]
11378 *) Lightly edited sample config files to refer people to our documentation
11379 instead of NCSA's, and to list Rob McCool as *original* author (also
11380 deleted his old, and no doubt non-functional email address). Would be
11381 nice to have examples of new features...
11383 Changes with Apache 0.8.2 19 Jul 1995
11385 *) Added AddLanuage code [Florent Guillaume]
11387 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
11389 *) All sorts of problems when MultiViews finds a directory. It would
11390 be nice if mod_dir.c was robust enough to handle that, but for now,
11391 just punt. [reported by Brian Behlendorf]
11393 *) Wait for all children on restart, to make sure that the old socket
11394 is gone and we can reopen it. [reported by Randy Terbush]
11396 *) Imagemap module is enabled in default Configuration
11398 *) RefererLog and UserAgentLog modules properly default the logfile
11401 *) Mark Cox's mod_cookies added to the distribution as an optional
11402 module (commented out in the default Configuration, and noted as
11403 an experiment, along with mod_dld). [Mark Cox]
11405 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
11407 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
11409 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
11411 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
11414 Changes with Apache 0.8.1
11416 *) New imagemap module [Randy Terbush]
11418 *) Replacement referer log module with NCSA-compatible RefererIgnore
11419 [Matthew Gray again]
11421 *) Don't mung directory listings with very long filenames.
11422 [Florent Guillaume]
11424 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
11426 *) New config script. See INSTALL for info. [Robert Thau]
11428 *) Scoreboard mechanism for regulating the number of extant server
11429 processes. MaxServers and StartServers defaults are the same as
11430 for NCSA, but the meanings are slightly different. (Actually,
11431 I should probably lower the MaxServers default to 10).
11433 Before asking for a new connection, each server process checks
11434 the number of other servers which are also waiting for a
11435 connection. If there are more than MaxServers, it quietly dies
11436 off. Conversely, every second, the root, or caretaker, process
11437 looks to see how many servers are waiting for a new connection;
11438 if there are fewer than StartServers, it starts a new one. This
11439 does not depend on the number of server processes already extant.
11440 The accounting is arranged through a "scoreboard" file, named
11441 /tmp/htstatus.*, on which each process has an independent file
11442 descriptor (they need to seek without interference).
11444 The end effect is that MaxServers is the maximum number of
11445 servers on an *inactive* server machine, but more will be forked
11446 off to handle unusually heavy loads (or unusually slow clients);
11447 these will die off when they are no longer needed --- without
11448 reverting to the overhead of full forking operation. There is a
11449 hard maximum of 150 server processes compiled in, largely to
11450 avoid forking out of control and dragging the machine down.
11451 (This is arguably too high).
11453 In my server endurance tests, this mechanism did not appear to
11454 impose any significant overhead, even after I forced it to put the
11455 scoreboard file on a normal filesystem (which might have more
11456 overhead than tmpfs). [Robert Thau]
11458 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
11461 *) Read .htaccess files even in directory with <Directory> section.
11462 (Former incompatibility noted on mailing list, now fixed). [Robert
11465 *) "HEAD /" gives the client a "Bad Request" error message, rather
11466 than trying to send no body *and* no headers. [Cliff Skolnick].
11468 *) Don't produce double error reports for some very obscure cases
11469 mainly involving auth configuration (the "all modules decline to
11470 handle" case which is a sure sign of a server bug in most cases,
11471 but also happens when authentication is badly misconfigured).
11474 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
11475 it's *for*, and this sort of thing really shouldn't be cluttering
11476 up the Makefile). [Robert Thau]
11478 *) Incidental code cleanups in http_main.c --- stop dragging
11479 sa_client around; just declare it where used. [Robert Thau]
11481 *) Another acc-related fix. (It doesn't like const char
11482 in some places...). [Mark Cox]
11484 Changes with Shambhala 0.6.1 13 Jul 1995
11486 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
11487 Also, fixed auth typo in http_protocol.c unmasked by this fix.
11489 *) Compiles clean with acc on SunOS [Paul Sutton]
11491 *) Reordered modules in modules.c so that Redirect takes priority
11492 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
11493 believe it or not, he has an actual site with a ScriptAlias and
11494 a Redirect declared for the *exact same directory*. Even *my*
11495 compatibility fetish wouldn't motivate me to fix this if the fix
11496 required any effort, but it doesn't, so what the hey.
11498 *) Fixed to properly default several server_rec fields for virtual
11499 servers from the corresponding fields in the main server_rec.
11500 [Cliff Skolnick --- 'port' was a particular irritant].
11502 *) No longer kills off nph- child processes before they are
11503 finished sending output. [Matthew Gray]
11505 Changes with Shambhala 0.6.0 10 Jul 1995
11507 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
11508 the connection to the client in an "aborted" state, but otherwise
11509 allow whatever handlers are running to clean up. hard_timeout()s
11510 abort the request in progress completely; anything not tied to some
11511 resource pool cleanup will leak. They're still around because I
11512 haven't yet come up with a more elegant way of handling
11513 timeouts when talking to something that isn't the client. The
11514 default_handler and the dir_handler now use soft timeouts, largely
11515 so I can test the feature. [Robert Thau]
11517 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
11518 the case of log handlers dying prematurely is probably handled VERY
11519 gracelessly at this point, and if the logger stops reading input,
11520 the server will hang. (It is known to correctly restart the
11521 logging process on server restart; this is (should be!) going through
11522 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
11523 script). [Robert Thau]
11525 *) asis files supported (new module). [Robert Thau]
11527 *) IdentityCheck code is compiled in, but has not been tested. (I
11528 don't know anyone who runs identd). [Robert Thau]
11530 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
11531 came in with the request, for NCSA bug-compatibility. [Robert Thau]
11533 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
11535 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
11536 as timeouts are not in scope. [Robert Thau]
11538 *) quoted-string args in config files now handled correctly (doesn't drop
11539 the last character). [Robert Thau; reported by Randy Terbush]
11541 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
11542 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
11544 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
11545 default default type); the former default default behavior when all
11546 type-checkers defaulted had been a core dump. [Paul Sutton]
11548 *) Copy filenames out of the struct dirent when indexing
11549 directories. (On Linux, readdir() returns a pointer to the same
11550 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
11552 Changes with Shambhala 0.5.3 [not released]
11554 *) Default response handler notes "file not found" in the error log,
11555 if the file was not found. [Cliff Skolnick].
11557 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
11558 code no longer sets up bogus PATH_INFO which fakes out the directory
11559 handler). [Cliff Skolnick]
11561 Changes with Shambhala 0.5.2 06 Jul 1995
11563 *) Changes to http_main.c --- root server no longer plays silly
11564 games with SIGCHLD, and so now detects and replaces dying
11565 children. Child processes just die on SIGTERM, without taking
11566 the whole process group with them. Potential problem --- if any
11567 child process refuses to die, we hang in restart.
11568 MaxRequestsPerChild may still not work, but it certainly works
11569 better than it did before this! [Robert Thau]
11571 *) mod_dir.c bug fixes: ReadmeName and HeaderName
11572 work (or work better, at least); over-long description lines
11573 properly terminated. [Mark Cox]
11575 *) http_request.c now calls unescape_url() more places where it
11576 should [Paul Sutton].
11578 *) More directory handling bugs (reported by Cox)
11579 Parent Directory link is now set correctly. [Robert Thau]
11581 Changes with Shambhala 0.5.1 04 Jul 1995
11583 *) Generalized cleanup interface in alloc.c --- any function can be
11584 registered with alloc.c as a cleanup for a resource pool;
11585 tracking of files and file descriptors has been reimplemented in
11586 terms of this interface, so I can give it some sort of a test.
11589 *) More changes in alloc.c --- new cleanup_for_exec() function,
11590 which tracks down and closes all file descriptors which have been
11591 registered with the alloc.c machinery before the server exec()s a
11592 child process for CGI or <!--#exec-->. CGI children now get
11593 started with exactly three file descriptors open. Hopefully,
11594 this cures the problem Rob H. was having with overly persistent
11595 CGI connections. [Robert Thau]
11597 *) Mutual exclusion around the accept() in child_main() --- this is
11598 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
11599 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
11600 This uses fcntl(F_SETLK,...) on the error log descriptor because
11601 flock() on that descriptor won't work on systems which have BSD
11602 flock() semantics, including (I think) Linux 1.3 and Solaris.
11604 This does work on SunOS (when the server is idle, only one
11605 process in the pool is waiting on accept()); it *ought* to work
11606 on the other systems. [Robert Thau]
11608 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
11610 *) sizeof(*sa_client) bugfix from [Rob Hartill]
11612 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
11614 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
11615 be unnecessary if I go to the revised timeout-handling scheme).
11618 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
11619 string) even if none came in with the request. [Robert Thau]
11621 *) CHANGES file added to distribution ;-).
11623 Changes with Shambhala 0.4.5
11625 *) mod_dld --- early dynamic loading support [rst]
11626 *) Add wildcard content handlers for XBITHACK; default_hander now
11627 invoked with that mechanism (as a handler hanging off mod_core) [rst]
11628 *) XBITHACK supported as a wildcard content-handler, and
11629 configurable at run-time (not just at compile time, as in the
11630 "patchy server" releases) [rst]
11632 Changes with Shambhala 0.4.4 30 Jun 1995
11634 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
11635 *) Handle Addtype x/y .z [rst, reported by Cox]
11637 Changes with Shambhala 0.4.3
11639 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
11640 synonymous [rst, terbush]
11642 Changes with Shambhala 0.4.1 28 Jun 1995
11644 *) First-cut virtual host implementation; some refit in the config
11645 reading code, and log management, was necessary to support this [rst]
11646 *) Sub-pool machinery, originally added to avoid excessive storage
11647 allocation on listings of large directories (which turned out to
11648 be the problem that the 0.3 storage accounting was added to
11649 find). Subrequests and mod_dir changed to use subpools. [rst]
11650 *) More memory debugging --- free list consistency checks. [rst]
11651 *) Added err_headers to request_rec, with support elsewhere [rst]
11652 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
11654 Changes with Shambhala 0.3 19 Jun 1995
11656 *) Switch ONE_PROCESS to a runtime command-line option (-X)
11657 *) Don't compile in mod_ai_backcompat by default
11658 *) Switch name of server from Apache to Shambhala in Makefile
11659 *) Add some accounting routines to track memory usage in the pools,
11662 Changes with Shambhala 0.2
11664 *) Set DOCUMENT_ROOT CGI variable
11665 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
11666 *) Add critical section protection to handling of cleanup structures
11668 *) Significant code reorg within the server core to group related
11669 functions together [rst]
11670 *) Correctly handle clients that hang up before sending any request
11672 *) Replace dying child processes. [rst]
11674 Changes with Shambhala 0.1 12 Jun 1995
11676 Major rewrite of the pre-existing "patchy server" codebase, by
11677 Robert Thau (rst). Significant portions of the server code, such
11678 as configuration-file handling and HTTP authentication support,
11679 were ripped out and rewritten from scratch. Code that was not
11680 completely rewritten was significantly altered.
11682 Major changes with this release include:
11684 *) Introduction of the module API; in request handling, the central
11685 machinery just dispatches to various modules, which actually do
11686 most of the work. Configuration handling is similar --- modules
11687 declare their own commands, and the central machinery just
11688 dispatches to them.
11690 API features from shambhala/0.1 were substantially unchanged in
11691 Apache 1.0 and 1.1. (1.0 API features not yet present in this
11692 release, such as wildcard handlers and subpools, were added in
11693 subsequent Shambhala releases, and were also generally rst's
11696 *) This release included the following modules:
11698 mod_access (access control --- allow and deny directives),
11699 mod_alias (Alias and Redirect commands),
11700 mod_auth (straight HTTP authentication, based on flat-files)
11701 mod_auth_dbm (same, with dbm files)
11702 mod_cgi (CGI scripts and, in this release, ScriptAlias)
11703 mod_common_log (CLF access logs; later renamed mod_log_common)
11704 mod_dir (directory indexing)
11705 mod_include (server-side includes)
11706 mod_mime (AddType directives)
11707 mod_negotiation (content negotiation)
11708 mod_userdir (support for users' public_html directories)
11710 It also included a mod_ai_backcompat, which was a private hack
11711 for back-compatibility with rst's own AI-lab servers.
11713 All of these modules were substantially complete, and functional
11714 or nearly so (a few, which implemented features not in use at
11715 Thau's site, required patches of a few lines).
11717 *) sub-request machinery, to allow modules to determine how other
11718 modules would assign MIME types to a given file, or optionally
11719 serve its content (this is heavily used by mod_dir, mod_include
11720 and mod_negotiation).
11722 *) Resource pool system for keeping track of memory allocated and
11723 files opened in service of a particular request. Much of the
11724 code in the modules (when they weren't rewrites) was adjusted to
11725 replace a pervasive convention of using fixed-size buffers on
11726 the stack with an equally pervasive convention of using memory
11727 allocated with palloc().
11729 *) Reorganization of data structures associated with a given
11730 request to eliminate use of global variables and the troublesome
11731 unmunge_name function (used in NCSA and early Apache releases to
11732 attempt to determine the URI which mapped to a given filename
11733 --- a difficult proposition, given that it is easy to produce
11734 setups in which multiple URIs map to the same file).
11736 *) Source files renamed and rearranged
11738 *) Very simple pre-forking behavior --- parent process forked off a
11739 fixed number of children, and then just waited for SIGHUP.
11741 *) Other more minor changes too numerous to list.
11743 This release included modified versions of a lot of code from the
11744 Apache 0.6.4 public release, plus an early pre-forking patch
11745 codeveloped by Robert Thau and Rob Hartill.
11747 Changes with Apache 0.7.3 20 Jun 1995
11749 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
11750 were incorporated by Rob Hartill on the main branch while Robert Thau
11751 worked on the Shambhala rewrite above. Most were merged into the
11752 Shambala architecture after Apache 0.8.0.
11754 Changes with Apache 0.6.4 13 May 1995
11756 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
11759 Changes with Apache 0.5.1 10 Apr 1995
11761 Changes with Apache 0.4 02 Apr 1995
11763 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
11766 Changes with Apache 0.3 24 Mar 1995
11768 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
11771 Changes with Apache 0.2 18 Mar 1995
11773 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
11774 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
11775 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
