1 Changes with Apache 2.0.37
3 Changes with Apache 2.0.36
5 *) Changes to the worker MPM's queue management and thread
6 synchronization code to reduce mutex contention [Brian Pane]
8 *) Don't install *.in configuration files since we already install
9 *-std.conf files. [Aaron Bannert]
11 *) Many improvements to the threadpool MPM. [Aaron Bannert]
13 *) Fix subreqs that are promoted via fast_redirect from having invalid
14 frec->r structures. This would cause subtle errors later on in
15 request processing such as seen in PR 7966. [Justin Erenkrantz]
17 *) More efficient pool recycling logic for the worker MPM [Brian Pane]
19 *) Modify the worker MPM to not accept() new connections until
20 there is an available worker thread. This prevents queued
21 connections from starving for processing time while long-running
22 connections were hogging all the available threads. [Aaron Bannert]
24 *) Convert the worker MPM's fdqueue from a LIFO back into a FIFO.
27 *) Get basic HTTP proxy working on EBCDIC machines. [Jeff Trawick]
29 *) Allow mod_unique_id to work on systems with no IPv4 address
30 corresponding to their host name. [Jeff Trawick]
32 *) Fix suexec behavior with user directories. PR 7810.
33 [Colm <colmmacc@redbrick.dcu.ie>]
35 *) Reject a blank UserDir directive since it is ambiguous. PR 8472.
38 *) Make mod_mime use case-insensitive matching when examining
39 extensions on all platforms. PR 8223. [Justin Erenkrantz]
41 *) Add an intelligent error message should no proxy submodules be
42 valid to handle a request. PR 8407 [Graham Leggett]
44 *) Major improvements in concurrent processing for AB by enabling
45 non-blocking connect()s and preventing APR from doing blocking
46 read()s. Also implement fatal error checking for apr_recv().
49 *) Fix Win32 NTFS Junctions (symlinks). PR 8014 [William Rowe]
51 *) Fix Win32 'short name' aliases in httpd.conf directives.
52 PR 8009 [William Rowe]
54 *) Fix generation of default httpd.conf when the layout paths are
55 disjoint. PR 7979, 8227. [Justin Erenkrantz]
57 *) Swap downgrade-1.0 and force-response-1.0 conditional checks so
58 that downgraded responses can have force-response. PR 8357.
61 *) Fix perchild MPM so that it can be configured with the move to the
62 experimental directory. [Scott Lamb <slamb@slamb.org>]
64 *) Fix perchild MPM so that it uses ap_gname2id for groups instead of
65 ap_uname2id. [Scott Lamb <slamb@slamb.org>]
67 *) Fix AcceptPathInfo. PR 8234 [Cliff Woolley]
69 *) [Security] Added the APLOG_TOCLIENT flag to ap_log_rerror() to
70 explicitly tell the server that warning messages should be sent
71 to the client in addition to being recorded in the error log.
72 Prior to this change, ap_log_rerror() always sent warning
73 messages to the client. In one case, a faulty CGI script caused
74 the server to send a warning message to the client that contained
75 the full path to the CGI script. This could be considered a
76 minor security exposure. [Bill Stoddard]
78 *) mod_autoindex output when SuppressRules was specified would
79 omit the first carriage return so the first item in the list
80 would appear to the right of the column headings instead of
81 underneath them. PR 8016 [David Shane Holden <dpejesh@yahoo.com>]
83 *) Moved the call to apr_mmap_dup outside the error branch so
84 that it would actually get called. This fixes a core dump
85 at init everytime you use the MMapFile directive. PR 8314
88 *) Trigger an error when a LoadModule directive attempts to
89 load a module which is built-in. This is a common error when
90 switching from a DSO build to a static build. [Jeff Trawick]
92 *) Change instdso.sh to use libtool --install everywhere and then
93 clean up some stray files and symlinks that libtool leaves around
94 on some platforms. This gets subversion building properly since
95 it needed a re-link to be performed by libtool at install time,
96 and the old instdso.sh logic to simply cp the DSO didn't handle
97 that requirement. [Sander Striker]
99 *) Allow VPATH builds to succeed when configured from an empty
100 directory. [Thom May <thom@planetarytramp.net>]
102 *) Fix 'control reaches end of non-void function' warning in
103 server/log.c. [Ben Collins-Sussman <sussman@collab.net>]
105 *) Perchild MPM is now correctly deemed as experimental and is now
106 located in server/mpm/experimental. [Justin Erenkrantz]
108 *) Fix segfault in mod_mem_cache when garabge collecting an expired
109 cache entry. [Bill Stoddard]
111 *) Introduced -E startup_logfile_name option to httpd to allow admins
112 to begin logging errors immediately. This provides Win32 users
113 an alternative to sending startup errors to the event viewer, and
114 allows other daemon tool authors an alternative to logging to stderr.
117 *) Fix subreqs with non-defined Content-Types being served improperly.
120 *) Merge in latest GNU config.guess and config.sub files. PR 7818.
123 *) Move 100 - Continue support to the HTTP_IN filter so that filters
124 are guaranteed to support 100 - Continue logic without any
125 intervention. [Justin Erenkrantz]
127 *) Add HTTP chunked input trailer support. [Justin Erenkrantz]
129 *) Rename and export get_mime_headers as ap_get_mime_headers.
132 *) Allow empty Host: header arguments. PR 7441. [Justin Erenkrantz]
134 *) Properly substitute sbindir as httpd's location in apachectl. PR 7840.
135 [Andreas Hasenack <andreas@netbank.com.br>]
137 *) Allow Win32 shebang scripts to follow the path (or omit the .exe
138 suffix from the shebang command), and allow ScriptInterpreterSource
139 Registry or RegistryStrict to override shebang lines, as 1.3 did.
142 *) worker MPM: Fix a situation where a child exited without releasing
143 the accept mutex. Depending on the OS and mutex mechanism this
144 could result in a hang. [Jeff Trawick]
146 *) Update the instructions for how to get started with mod_example.
149 *) Fix PidFile to default to rel_runtimedir instead of
150 rel_logfiledir. PR 7841. [Andreas Hasenack <andreas@netbank.com.br>]
152 *) Win32: Fix problem that caused rapid performance degradation
153 when number of connecting clients exceeded ThreadsPerChild.
156 *) Fixed a segfault parsing large SSIs on non-mmap systems.
159 *) Proxy was bombing out every second keepalive request, caused by a
160 stray CRLF before the second response's status line. Proxy now
161 tries to read one more line if it encounters a CRLF where it
162 expected a status. PR 10010 [Graham Leggett]
164 *) Deprecated the apr_lock.h API. Please see the following files
165 for the improved thread and process locking and signaling:
166 apr_proc_mutex.h, apr_thread_mutex.h, apr_thread_rwlock.h,
167 apr_thread_cond.h, and apr_global_mutex.h. [Aaron Bannert]
169 *) Change mod_status to use scoreboard accessor functions so it can
170 be used in any MPM without having to be recompiled.
171 [Ryan Morgan <rmorgan@covalent.net>]
173 *) Fix parsing of some AP_DECLARE_DATA declarations so that the filter
174 handle declarations are recognized. This fixes problems loading
175 mod_autoindex on some platforms. [Brian Havard]
177 *) add optional fixup hook to proxy [Daniel Lopez <daniel@covalent.net>]
179 *) Remind the admin about the User and Group directives when we are
180 unable to set permissions on a semaphore. PR 7812 [Jeff Trawick]
182 *) fix possible compilation problem in ssl_engine_kernel.c. PR 7802
185 *) fix possible infinite loop in mod_ssl triggered by certain
186 netscape clients [Doug MacEachern]
188 *) fix ProxyPass when frontend is https and backend is http
191 *) Add DASL support to mod_dav
192 [Sung Kim <hunkim@cse.ucsc.edu>]
194 Changes with Apache 2.0.35
196 *) mod_rewrite: updated to use the new APR global mutex type.
199 *) Fixes for mod_include errors on boundary conditions in which
200 "<!--#" occurs at the very end of a bucket
201 [Paul Reder, Brian Pane]
203 *) worker, prefork, perchild, beos MPMs: Add -DFOREGROUND switch to
204 cause the Apache parent process to run in the foreground (similar to
205 -DNO_DETACH except that it doesn't switch session ids).
208 *) Added support for Posix semaphore mutex locking (AcceptMutex posixsem)
209 for those platforms that support it. If using the default
210 implementation, this is between pthread and sysvsem in priority.
211 This implies it's the new default for Darwin. [Jim Jagielski]
213 *) AIX: Fix the syntax for setting the LDR_CNTRL and AIXTHREAD_SCOPE
214 environment variables in the envvars file. [Jeff Trawick]
216 *) worker MPM: Don't create a listener thread until we have a worker
217 thread. Otherwise, in situations where we'll have to wait a while
218 to take over scoreboard slots from a previous generation, we'll be
219 accepting connections we can't process yet. [Jeff Trawick]
221 *) Allow worker MPM to build on systems without pthread_kill().
222 [Pier Fumagalli, Jeff Trawick]
224 *) Prevent ap_add_output_filters_by_type from being called in
225 ap_set_content_type if the content-type hasn't changed.
228 *) Performance: implemented the bucket allocator made possible by the
229 API change in 2.0.34. [Cliff Woolley]
231 *) Don't allow initialization to succeed if we can't get a socket
232 corresponding to one of the Listen statements. [Jeff Trawick]
234 Changes with Apache 2.0.34
236 *) Allow all Perchild directives to accept either numerical UID/GID
237 or logical user/group names. [Scott Lamb <slamb@slamb.org>]
239 *) Make Perchild compile cleanly and serve pages again. [Ryan Bloom]
241 *) implement ssl proxy to support ProxyPass / https:// and the
242 SSLProxy* directives [Doug MacEachern]
244 *) Update mod_cgid to not do single-byte socket reads for CGI headers
247 *) Made AB's use of the Host: header rfc2616 compliant
248 by Taisuke Yamada <tai@iij.ad.jp> [Dirk-Willem van Gulik].
250 *) The old, legacy (and unused) code in which the scoreboard was totally
251 and completely contained in a file (SCOREBOARD_FILE) has been
252 removed. This does not affect scoreboards which are *mapped* to
253 files using named-shared-memory. [Jim Jagielski]
255 *) Change bucket brigades API to allow a "bucket allocator" to be
256 passed in at certain points. This allows us to implement freelists
257 so that we can stop using malloc/free so frequently.
258 [Cliff Woolley, Brian Pane]
260 *) Add support for macro expansion within the variable names in
261 <!--#echo--> and <!--#set--> directives [Brian Pane]
263 *) Fix some mod_include segfaults [Cliff Woolley, Brian Pane, Brad Nicholes]
265 *) Update the "RedHat" Layout to match Red Hat Linux version 7. PR BZ-7422
268 *) add compat layer to support RSA SSLC 1.x and 2.x in mod_ssl
269 [Jon Travis, John Barbee, William Rowe, Ryan Bloom, Doug MacEachern]
271 *) Add a new parameter to the quick_handler hook to instruct
272 quick handlers to optionally do a lookup rather than actually
273 serve content. This is the first of several changes required fix
274 several problems with how quick handlers work with subrequests.
277 *) worker MPM: Get MaxRequestsPerChild to work again. [Jeff Trawick]
279 *) [APR-related] The ordering of the default accept mutex method has
280 been changed to better match what's done in Apache 1.3. The ordering
281 is now (highest to lowest): pthread -> sysvsem -> fcntl -> flock.
284 *) Ensure that the build/ directory is created when using VPATH.
287 *) Add some popular types to the mime magic file. PR 7730.
288 [Linus Walleij <triad@df.lth.se>, Justin Erenkrantz]
290 *) Remove the single-byte socket reads for CGI headers [Brian Pane]
292 *) When a proxied site was being served, Apache was replacing
293 the original site Server header with it's own, which is not
294 allowed by RFC2616. Fixed. [Graham Leggett]
296 *) Fix a mod_cgid problem that left daemon processes stranded
297 in some server restart scenarios. [Jeff Trawick]
299 *) Added exp_foo and rel_foo variables to config_vars.mk for
300 all Apache and Autoconf path variables (like --sysconfdir,
301 --sbindir, etc). exp_foo is the "expanded" version, which means
302 that all internal variable references have been interpolated.
303 rel_foo is the same as $exp_foo, only relative to $prefix if they
304 share a common path. [Aaron Bannert]
306 *) Fix some restart/terminate problems in the worker MPM. Don't
307 drop connections during graceful restart. [Jeff Trawick]
309 *) Change the header merging behaviour in proxy, as some headers
310 (like Set-Cookie) cannot be unmerged due to stray commas in
311 dates. [Graham Leggett]
313 *) Be more vocal about what AcceptMutex values we allow, to make
314 us closer to how 1.3 does it. [Jim Jagielski]
316 *) Get nph- CGI scripts working again. PRs 8902, 8907, 9983
319 *) Upgraded PCRE library to latest version 3.9 [Brian Pane]
321 *) Add accessor function to set r->content_type. From now on,
322 ap_rset_content_type() should be used to set r->content_type.
323 This change is required to properly implement the
324 AddOutputFilterByType configuration directive.
325 [Bill Stoddard, Sander Striker, Ryan Bloom]
327 *) Add new M_FOO symbols for the WebDAV/DeltaV methods specified by
328 RFC 3253. Improved the method name/number mapping functions.
331 *) remove sock_enable_linger from connection.c [Ian Holsman]
333 *) Fix for virtual host processing where the requested hostname
334 has a '.' at the end (PR 9187) [Ryan Cruse <ryan@estara.com>]
336 *) mod_dav's APIs for REPORT response handling was changed so that
337 providers can generate the content directly into the output filter
338 stack, rather than buffering the response into memory. [Greg Stein]
340 *) Fix a hang condition with graceful restart and prefork MPM
341 in the situation where MaxClients is very high but
342 much fewer servers are actually started at the time of the
343 restart. [Jeff Trawick]
345 *) Small performance fixes for mod_include [Brian Pane]
347 *) Performance improvement for the error logger [Brian Pane]
349 *) Change configure so that Solaris 8 and above have
350 SINGLE_LISTEN_UNSERIALIZED_ACCEPT defined by default.
351 according to sun people solaris 8+ doesn't have a thundering
352 herd problem [Ian Holsman]
354 *) Allow URIs specifying CGI scripts to include '/' at the end
355 (e.g., /cgi-bin/printenv/) on AIX and Solaris (and other OSs
356 which ignore '/' at the end of the names of non-directories).
357 PR 10138 [Jeff Trawick]
359 *) implement SSLSessionCache shmht and shmcb based on apr_rmm and
360 apr_shm. [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
362 *) Fix apxs -g handling. Move config_vars.mk from the top build
363 directory to the build directory. PR 10163 [Jeff Trawick]
365 *) Fix some mod_include problems which broke evaluation of some
366 expressions. PR 10108 [Jeff Trawick]
368 *) Fix the calculation of request time in mod_status. [Stas Bekman]
370 *) Fix the calculation of thread_num in the worker score structure.
373 *) Use apr_atomic operations in managing the mod_mem_cache
374 cache_objects for SMP scalability. (see USE_ATOMICS
375 preprocessor directive in mod_file_cache)
378 *) Add filehandle caching to mod_mem_cache. (see CACHE_FD
379 preprocessor directive in mod_file_cache)
382 *) Implement prototype mod_disk_cache for use with mod_cache.
385 *) Add a missing manualdir entry in the Debian config.layout.
386 [Thom May <thom@planetarytramp.net>]
388 *) Stop installing libtool for APR and tell APR where it should place
389 its copy of libtool (via our installbuildpath layout variable).
392 *) New directive ProxyIOBufferSize. Sets the size of the buffer used
393 when reading from a remote HTTP server in proxy. [Graham Leggett]
395 *) Modify receive/send loop in proxy_http and proxy_ftp so that
396 should it be necessary, the remote server socket is closed before
397 transmitting the last buffer (set by ProxyIOBufferSize) to the
398 client. This prevents the backend server from being forced to hang
399 around while the last few bytes are transmitted to a slow client.
400 Fix the case where no error checking was performed on the final
401 brigade in the loop. [Graham Leggett]
403 *) Scrap CacheMaxExpireMin and CacheDefaultExpireMin. Change
404 CacheMaxExpire and CacheDefaultExpire to use seconds rather than
405 hours. [Graham Leggett, Bill Stoddard]
407 *) New Directive SSIUndefinedEcho. to change the '(none)' echoed
408 for a undefined variable. [Ian Holsman]
410 *) Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
411 when we can't get a socket in the specified address family. We may
412 have gotten back an IPv6 address first and yet our system is not
413 configured to allow IPv6 sockets. [Jeff Trawick]
415 *) Be more careful about recursively removing CVS directories. Make
416 sure that we aren't cd'ing to their home directory first. PR: 9993
417 [Aaron Bannert, James LewisMoss <dres@lewismoss.net>]
419 *) Add a missing errordir entry in the Debian config.layout. PR: 10067
420 [Dirk-Jan Faber <dirk-jan@selwerd.nl>, Aaron Bannert,
421 Thom May <thom@planetarytramp.net>]
423 *) Rename the filter ordering priorities. The recent filtering fixes
424 have showcased problems with their usage. Therefore, we need to
425 rename them to increase the clarity. (CONTENT->RESOURCE,
426 HTTP_HEADER->CONTENT_SET/PROTOCOL) [Justin Erenkrantz]
428 Changes with Apache 2.0.33
430 *) Fix a problem in the new --enable-layout functionality where
431 it wouldn't allow overrides from variables like --prefix,
432 --bindir, etc. [Thom May <thom@planetarytramp.net>]
434 *) Fix a bug in the core input filter for AP_MODE_EXHAUSTIVE. It
435 no longer hangs around waiting for the socket to close before
436 returning exhaustive data. [Aaron Bannert]
438 *) rename apr_exploded_time_t to apr_time_exp_t (as per renames pending)
439 [Thom May <thom@planetarytramp.net>]
441 *) Change mod_ssl to always do a full startup/teardown on restarts.
442 this allows mod_ssl to be added to a server that is already
443 running and makes it possible to add/change certs/keys after the
444 server has been started. [Doug MacEachern]
446 *) Introduce PassPhraseDialog "|/path/to/pipe" mechanism to mod_ssl.
447 This pipe must be a bidirectional 'console' style relay, which
448 mod_ssl prints all prompts to the pipe's stdin, and reads the
449 passphrases from the pipe's stdout. [William Rowe]
451 *) Fix bug where --sysconfdir and --localstatedir were being
452 ignored. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
455 *) Fix --enable-layout to work again. Caution: When specifying
456 --enable-layout, common arguments like --prefix, --exec-prefix,
457 etc. will be ignored and the settings from the layout will be
458 used instead. [Thom May <thom@planetarytramp.net>, Aaron Bannert]
461 *) New Directive for mod_proxy: ProxyRemoteMatch. This provides
462 regex pattern matching for the determination of which requests
463 to use the remote proxy for. [Jim Jagielski]
465 *) Fix CustomLog bytes-sent with HTTP 0.9. [Justin Erenkrantz]
467 *) Prevent Apache from ignoring SIGHUP due to some lingering 1.3
468 cruft in piped logs and rewritemap child processes.
471 *) All instances of apr_lock_t have been removed and converted
472 to one of the following new lock APIs: apr_thread_mutex.h,
473 apr_proc_mutex.h, or apr_global_mutex.h. No new code should
474 use the apr_lock.h API, as the old API will soon be deprecated.
477 *) Merged in changes to mod_ssl up through 2.8.7-1.3.23.
478 [Ralf S. Engelschall, Cliff Woolley]
480 *) mod-include: make it handle flush'es and fix the 'false-alarm'
481 [Justin Erenkrantz, Brian Pane, Ian Holsman]
483 *) ap_get_*_filter_handle() functions to allow 3rd party modules
484 to lookup filter handles so they can bypass the filter name
485 lookup when adding filters to a request (via ap_add_*_filter_handle())
486 [Ryan Morgan <rmorgan@covalent.net>]
488 *) Fix for multiple file buckets on Win32, where the first file
489 bucket would cause the immediate closure of the socket on any
490 non-keepalive requests. [Ryan Morgan <rmorgan@covalent.net>]
492 *) Correct Win32 failure of mmap of a segment beyond start of the
493 file; fixes large SSL and similar transfers. [William Rowe]
496 *) Implement apr_proc_detach changes and allow -DNO_DETACH in the
497 multi-process mode to not "daemonize" while detaching from the
498 controlling terminal. This is necessary for Apache to work with
499 process-management tools like AIX's "System Resource Controller"
500 as well as Dan Bernstein's "daemontools".
501 [Jos Backus <josb@cncdsl.com>, Aaron Bannert]
503 *) Convert mod_auth_digest to use the new apr_global_mutex_t
504 type. [Aaron Bannert]
506 *) fix bug in mod-include where it wouldn't send a unmatched
507 part if it was at the end of a bucket [Ian Holsman]
509 *) worker MPM: Improve logging of errors with the interface between
510 the listener thread and worker threads. [Jeff Trawick]
512 *) Some browsers ignore cookies that have been merged into a
513 single Set-Cookie header. Set-Cookie and Set-Cookie2 headers
514 are now unmerged in the http proxy before being sent to the
515 client. [Graham Leggett]
517 *) Fix a problem with proxy where each entry of a duplicated
518 header such as Set-Cookie would overwrite and obliterate the
519 previous value of the header, resulting in multiple header
520 values (like cookies) going missing.
521 [Graham Leggett, Joshua Slive]
523 *) Add the server-limit and thread-limit values to the scoreboard
524 for the sake of third-party applications.
525 [Adam Sussman <myddryn@vishnu.vidya.com>]
527 *) Fix segfault when proxy recieves an invalid HTTP response [Ian Holsman]
529 *) OS/390: Get make install to properly copy DSO modules.
532 *) Win32: Fix bug in mod_status with displaying "Restart Time"
536 *) Fix IPv6 name-based virtual hosts. [Jeff Trawick]
538 *) Introduce AddOutputFilterByType directive. [Justin Erenkrantz]
540 *) Fix DEBUG_CGI support in mod_cgi. PR 9670, 9671.
541 [David MacKenzie <djm@pix.net>]
543 *) Fix incorrect check for script_in in mod_cgi. PR 9669.
544 [David MacKenzie <djm@pix.net>]
546 *) Fix segfault and display error when SSLMutex file can not be
547 created. [Adam Sussman <myddryn@vishnu.vidya.com>]
549 *) Add reference counting to mod_mem_cache cache objects to
550 better manage removing objects from the cache.
553 *) Change the verbage on the ScoreBoardFile in our default configs.
554 Also change the default to be commented out (unspecified) so we
555 get anonymous shared memory by default. [Aaron Bannert]
557 *) Implement new ScoreBoardFile directive logic. This affects how
558 we create the scoreboard's shared memory segment. If the directive
559 is present, a name-based segment is created. If the directive is
560 not present, first an anonymous segment is created, and if that
561 fails, a name-based segment is created from a file of the name
562 DEFAULT_SCOREBOARD. This gives third-party applications the
563 ability to access our scoreboard. [Aaron Bannert]
565 *) Allow mod_deflate to work with non-GET requests and properly send
566 Content-Lengths. [Sander Striker <striker@apache.org>]
568 *) Fix ap_directory_merge() to correctly merge configs when there is
569 no <Directory /> block. [Justin Erenkrantz, William Rowe]
571 *) Remove spurious debug messsages that are normal under HTTP
572 keep-alive logic. [Jeff Trawick, Justin Erenkrantz]
574 *) Fix a bug in mod_cgid that would prevent proper shutdown death
575 of the cgid process. [Aaron Bannert]
577 *) Add signal handling back in to the worker MPM for the one_process
578 (-X, -DDEBUG, -DONE_PROCESS) case. [Aaron Bannert]
580 *) Performance: Reuse per-connection transaction pools in the
581 worker MPM, rather than destroying and recreating them. [Brian Pane]
583 *) Remove all signals from the worker MPM's child process. Instead,
584 the parent uses the Pipe of Death for all communication with the
585 child processes. [Ryan Bloom]
587 Changes with Apache 2.0.32
589 *) mod_negotiation: ForceLanguagePriority now uses 'Prefer' as the
590 default if the directive is not specified. This mirrors older
591 behavior without changes to the httpd.conf. [William Rowe]
593 *) Win32: solve the win32 service problems in 2.0.31-alpha, by fixing
594 the service, mpm and logging code, and bugs in apr_file_open_stderr
595 and apr_file_dup2 functions. Win2K/XP services have no handles
596 associated for stdin/out/err, which caused unpredictable behavior
597 in the prior release. [William Rowe, Bill Stoddard]
599 *) Win32: simplify the Application Event Log messages, since there isn't
600 likely to be 'more information in the error log' before an error log
601 has been opened. [William Rowe]
603 *) Win32: substantial cleanup to the mpm_winnt code for legibility and
604 to follow the program flow of other MPMs. [Ryan Bloom, William Rowe]
606 *) Win32: apache -k shutdown now behaves like apache -k stop.
609 *) Fix prefork to not kill the parent if a child hits a resource shortage
610 on accept(). [Greg Ames]
612 *) Fix seg faults that occur when what should be the httpd request line
613 starts with \r\n followed by garbage. [Greg Ames]
615 *) Allow statically linked support binaries with the new
616 --enable-static-support flag, and enable this behavior in
617 the binbuild script. Also add a new --enable-static-htdbm
618 flag. [Aaron Bannert]
620 *) Allow mod_autoindex to serve symlinks if permitted and attempt to
621 do only one stat() call when generating the directory listings.
624 *) Fix resolve_symlink to save the original symlink name if known.
627 *) Be a bit more sane with regard to CanonicalNames. If the user has
628 specified they want to use the CanonicalName, but they have not
629 configured a port with the ServerName, then use the same port that
630 the original request used. [Ryan Bloom and Ken Coar]
632 *) In core_input_filter, check for an empty brigade after
633 APR_BRIGADE_NORMALIZE(). Otherwise, we can get segfaults if a
634 client says it will post some data but we get FIN before any
635 data arrives. [Jeff Trawick]
637 *) Not being able to bind to the socket is a fatal error. We should
638 print an error to the console, and return a non-zero status code.
639 With these changes, all of the Unix MPMs do that correctly.
642 *) suexec: Allow HTTPS and SSL_* environment variables to be passed
643 through to CGI scripts. PR 9163
644 [Brian Reid <breid@customlogic.com>,
645 Zvi Har'El <rl@math.technion.ac.il>]
647 *) binbuild.sh: Make sure that we use the expat from our source
648 tree so that there aren't any surprises on the target machine.
651 *) mod_cgid: Add retry logic for when the daemon can't fork fast
652 enough to keep up with new requests. Start using
653 HTTP_SERVER_UNAVAILABLE instead of HTTP_INTERNAL_SERVER_ERROR
654 when we can't talk to the daemon. [Jeff Trawick]
656 *) apxs: LTFLAGS envvar can override default libtool options. Try
657 "LTFLAGS=' ' apxs -c mod_foo.c" to see what libtool does under
658 the covers. [Jeff Trawick]
660 *) The Location: response header field, used for external
661 redirect, *must* be an absoluteURI. The Redirect directive
662 tested for that, but RedirectMatch didn't -- it would allow
663 almost anything through. Now it will try to turn an abs_path
664 into an absoluteURI, but it will correctly varf like Redirect
665 if the final redirection target isn't an absoluteURI. [Ken Coar]
667 Changes with Apache 2.0.31
669 *) Create the scoreboard (in the parent) in a global pool context,
670 so it survives graceful restarts. This fixes a SEGV during
671 graceful restarts. [Aaron Bannert]
673 *) Add a timeout option to the proxy code 'ProxyTimeout'
676 *) FTP directory listings are now always retrieved in ASCII mode.
677 The FTP proxy properly escapes URI's and HTML in the generated
678 listing, and escapes the path components when talking to the FTP
679 server. It is now possible to browse the root directory by using
680 a url like: ftp://user@host/%2f/ (ported from apache_1.3.24)
681 Also, the last path component may contain wildcard characters
682 '*' and '?', and if they do, a directory listing is created instead
683 of a file retrieval. Example: ftp://user@host/httpd/server/*.c
686 *) Added single-listener unserialized accept support to the
687 worker MPM [Brian Pane]
689 *) New Directive for mod_proxy: 'ProxyPreserveHost'. This passes
690 the incoming host header through to the proxied server
691 [Geoff <g.russell@ieee.org>]
693 *) New Directive Option for ProxyPass. It now can block a location
694 from being proxied [Jukka Pihl <jukka.pihl@entirem.com>]
696 *) Don't let the default handler try to serve a raw directory. At
697 best you get gibberish. Much worse things can happen depending
698 on the OS. [Jeff Trawick]
700 *) Change the pre_config hook to return a value. Modules can now emit
701 an error message and then cause the server to quit gracefully during
702 startup. This required a bump to the MMN. [Aaron Bannert]
704 *) Fix some unix socket descriptor leaks in the handler side of
705 mod_cgid (the part that runs in the server process). Whack a
706 silly "close(-1)" in the handler too. [Jeff Trawick]
708 *) Change the pre_mpm hook to return a value, so that scoreboard
709 init errors percolate up to code that knows how to exit
710 cleanly. This required a bump to the MMN. [Jeff Trawick]
712 *) Add the socket back to the conn_rec and remove the create_connection
713 hook. The create_connection hook had a design flaw that did not
714 allow creating connections based on vhost info. [Bill Stoddard]
716 *) Fixed PATH_INFO and QUERY_STRING from mod_negotiation results.
717 Resolves the common case of using negotation to resolve the request
718 /script/foo for /script.cgi/foo. [William Rowe]
720 *) Added new functions ap_add_(input|output)_filter_handle to
721 allow modules to bypass the usual filter name lookup when
722 adding hard-coded filters to a request [Brian Pane]
724 *) caching should now work on subrequests (still very experimental)
727 *) The Win32 mpm_winnt now has a shared scoreboard. [William Rowe]
729 *) Change ap_get_brigade prototype to use apr_off_t instead of apr_off_t*.
732 *) Refactor ap_rgetline so that it does not use an internal brigade.
733 Change ap_rgetline's prototype to return errors. [Justin Erenkrantz]
735 *) Remove mod_auth_db. [Justin Erenkrantz]
737 *) Do not install unnecessary pcre headers like config.h and internal.h.
738 [Joe Orton <joe@manyfish.co.uk>]
740 *) Change in quick_hanlder behavior for subrequests. it now passes DONE
741 (as it does for a normal request). quick_handled sub-requests now work
742 in mod-include [Ian Holsman]
744 *) Change SUBREQ_CORE so that it is a 'HTTP_HEADER' filter instead of
745 'CONTENT' one, as it needs to run AFTER all content headers
747 *) Rename BeOS MPM directive RequestsPerThread to MaxRequestsPerThread.
750 *) Split out blocking from the mode in the input filters.
753 *) Fix a segfault in mod_include. [Justin Erenkrantz, Jeff Trawick]
755 *) Cause Win32 to capture all child-worker process errors in
756 Apache to the main server error log, until the child can
757 open its own error logs. [William Rowe]
759 *) HPUX 11.*: Do not kill the child process when accept()
760 returns ENOBUFS on HPUX 11.*. (ported from a 1.3 patch
761 by [madhusudan_mathihalli@hp.com])
764 *) Fix a problem in the parsing of the <Proxy foo> directive.
767 *) rewrite of mod_ssl input filter for better performance and less
768 memory usage [Doug MacEachern]
770 *) allow quick_handler to be run on subrequests. [Ian Holsman]
772 *) mod_dav now asks its provider to place content directly into the
773 filter stack when handling a GET request. The mod_dav/provider
774 API has changed, so providers need to be updated. [Greg Stein]
776 *) Clear the output socket descriptor in unixd_accept() to make sure
777 we don't supply a bogus socket to the caller if the accept fails.
778 This caused problems with the worker MPM, which tried to process
779 the returned socket if it was non-NULL. [Brian Pane]
781 *) Move a check for an empty brigade to the start of core input filter
782 to avoid segfaults. [Justin Erenkrantz, Jeff Trawick]
784 *) Add FileETag directive to allow configurable control of what
785 data are used to form ETag values for file-based URIs. MMN
786 bumped to 20020111 because of fields added to the end of
787 the core_dir_config structure. [Ken Coar]
789 *) Fix a segfault in mod_rewrite's logging code caused by passing the
790 wrong config to ap_get_remote_host(). [Jeff Trawick]
792 *) Allow mod_cgid to work from a binary distribution install by
793 using 755 for the permissions on the log directory instead of
796 *) Fixed a segfault that happened during graceful shutdown (or when
797 the httpd ran out of file descriptors) with the worker MPM [Brian Pane]
799 *) Split all Win32 modules [excluding the core components mod_core,
800 mod_so, mod_win32 and the winnt mpm] into individual loadable
801 modules, so the administrator may individually disable the former
802 compiled-in modules by simply commenting out their LoadModule
803 directives. [William Rowe]
805 *) Saved Win32 module authors and porters many future headaches, by
806 duplicating the appropriate .h files such as os.h into the include
807 directory, including in the build tree. [William Rowe]
809 *) mod_ssl adjustments to help with using toolkits other than OpenSSL:
810 Use SSL functions/macros instead of directly dereferencing SSL
811 structures wherever possible.
812 Add type-casts for the cases where functions return a generic pointer.
813 Add $SSL/include to configure search path.
814 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
816 *) Moved several pointers out of the shared Scoreboard so it is
817 more portable, and will present the vhost name across server
818 generation restarts. [William Rowe]
820 *) Fix SSLPassPhraseDialog exec: and SSLRandomSeed exec:
823 Changes with Apache 2.0.30
825 *) Fix the main bug for FreeBSD and threaded MPM's. There are
826 still issues (see STATUS) but at least the server will now
827 run without crashing the machine.
828 [David Reid, Aaron Bannert, Justin Erenkrantz]
830 *) Fix a typo in mod_deflate's m4 config section.
831 [albert chin (china@thewrittenword.com)]
833 *) Fix a couple of mod_proxy problems forwarding HTTP connections
834 and handling CONNECT:
835 (1) PR #9190 Proxy failed to connect to IPv6 hosts.
836 (2) Proxy failed to connect when the first IP address returned by
837 the resolver was unreachable but a secondary IP address was.
840 *) Fix the module identifer as shown in the docs for various core
841 modules (e.g., the identifer for mod_log_config was previously
842 listed as config_log_module). PR #9338
843 [James Watson <ap2bug@sowega.org>]
845 *) Fix LimitRequestBody directive by placing it in the HTTP
846 filter. [Justin Erenkrantz]
848 *) Fix mod_proxy seg fault when the proxied server returns
849 an HTTP/0.9 response or a bogus status line.
852 *) Prevent mod_proxy from truncating one character off the
853 end of the status line returned from the proxied server.
854 [Adam Sussman, Bill Stoddard]
856 *) Eliminate loop in ap_proxy_string_read().
857 [Adam Sussman, Bill Stoddard]
859 *) Provide $0..$9 results from mod_include regex parsing.
862 *) Allow mod-include to look for alternate start & end tags [Ian Holsman]
864 *) Introduced the ForceLanguagePriority directive, to prevent
865 returning MULTIPLE_CHOICES or NONE_ACCEPTABLE in some cases,
866 when using Multiviews. [William Rowe]
868 *) Fix a problem which prevented mod_cgid and suexec from working
869 together reliably [Greg Ames]
871 *) Remove the call to exit() from within mod_auth_digest's post_config
872 phase. [Aaron Bannert]
874 *) Fix a problem in mod_auth_digest that could potentially cause
875 problems with initialized static data on a system that uses DSOs.
878 *) Fix a segfault in the worker MPM that could happen during
879 child process exits. [Brian Pane, Aaron Bannert]
881 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
883 *) Fix matching of vhosts by ip address so we find IPv4
884 vhost address when target address is v4-mapped form of
885 that address. [Jeff Trawick]
887 *) More performance tweaks to the BNDM string-search algorithm
888 used to find "<!--#" tokens in mod_include [Brian Pane]
890 *) Miscellaneous small performance fixes: optimized away various
891 string copy operations and removed large temp buffers from
892 the stack [Brian Pane]
894 *) Fixed startup segfault that occurred when a VirtualHost
895 directive had a port but no address [Brian Pane]
897 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
899 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
900 if oslevel < WINNT. This should fix several problems reported
901 Against 2.0.28 on Windows 98 [Bill Stoddard]
903 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
904 to fail. [Bill Stoddard]
906 *) Change core code to allow an MPM to set hard thread/server
907 limits at startup. prefork, worker, and perchild MPMs now have
908 directives to set these limits. [Jeff Trawick]
910 *) Win32: The async AcceptEx() event should be autoreset upon
911 successful completion of a wait (WaitForSingleObject). This
912 eliminates a number of spurious
913 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
916 *) Move any load library path environment variables out of
917 apachectl and into a separate environment variable file which
918 can be more easily tailored by the admin. The environment
919 variable file as built by Apache may have additional system-
920 specific settings. For example, on OS/390 we tailor the heap
921 settings to allow lots of threads. [Jeff Trawick]
923 *) Use the new APR pool code to reduce pool-related lock
924 contention in the worker MPM. [Sander Striker]
926 *) The POD no longer assumes the child is listening on 127.0.0.1
927 and now pulls the first hostname in the list of listeners to
928 perform the dummy connect on. This fixes a bug when the user
929 had configured the Listen directive for an IP other than
930 127.0.0.1. This would result in undead children and error
931 messages such as "Connection refused: connect to listener".
934 *) The worker MPM now respects the LockFile setting, needed to
935 avoid locking problems with NFS. [Jeff Trawick]
937 *) Fix segfault when worker MPM receives SIGHUP.
938 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
940 *) Fix bug that could potentially prevent the perchild MPM from
941 working with more than one vhost/uid. [Aaron Bannert]
943 *) Change make install and apxs -i processing of DSO modules to
944 perform special handling on platforms where libtool doesn't install
945 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
946 which prevented standard LoadModule statements from working.
949 *) Whenever mod_so is enabled (not just when there are DSOs for
950 our modules), do whatever special magic is required for compiling/
951 loading third-party modules. This allows third-party DSOs to
952 be used on an AIX build when there were no built-in modules
953 built as DSOs. (This should help on OS/390 and BeOS as well.)
956 *) Allow apxs to be used to build DSOs on AIX without requiring the
957 user to hard-code the list of import files. (This should help
958 on OS/390 and BeOS as well.) [Jeff Trawick]
960 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
961 PR 8563, 8919 [William Rowe]
963 *) Get binary builds working when libapr and libaprutil are built
966 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
967 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
968 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
970 *) Fix the handling of SSI directives in which the ">" of the
971 terminating "-->" is the last byte in a file [Brian Pane]
973 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
974 message that we had back in apache-1.3 and still have scattered
975 throughout our docs. [Aaron Bannert]
977 *) Prevent the Win32 port from continuing after encountering an
978 error in the command line args to apache. [William Rowe]
980 *) On a error in the proxy, make it write a line to the error log
983 *) Various mod_ssl performance improvements [Doug MacEachern]
985 Changes with Apache 2.0.29
987 *) Add buffering in core_output_filter to ensure that long
988 lists of small buckets don't cause small packet writes.
989 [Brian Pane, Ryan Bloom]
991 *) Fix the installation target to make sure that the manual is
992 installed in the correct location.
993 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
994 Gomez Henri <hgomez@slib.fr>]
996 *) Fix the cmd command for mod_include. When we are processing
997 a cmd command, we do not want to use the r->filename to set
998 the command name. The command comes from the SSI tag. To do this,
999 I added a variable to the function that builds the command line
1000 in mod_cgi. This allows the include_cmd function to specify
1001 the command line itself. [Ryan Bloom]
1003 *) Change open_logs hook to return a value, allowing you
1004 to flag a error while opening logs
1005 [Ian Holsman, Doug MacEachern]
1007 *) Change post_config hook to return a value, allowing you
1008 to flag a error post config
1009 [Ian Holsman, Jeff Trawick]
1011 *) Allow SUEXEC_BIN (the path to the suexec binary that is
1012 hard-coded into the server) to be specified to the configure
1013 script by the --with-suexec-bin parameter. [Aaron Bannert]
1015 *) Fix segv in worker MPM following accept on pipe-of-death
1018 *) Add mod_deflate to experimental.
1019 [Ian Holsman, Justin Erenkrantz]
1021 *) Bail out at configure time if an invalid MPM was specified.
1022 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1024 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
1025 configured [John Sterling <sterling@covalent.net>]
1027 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
1029 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
1031 *) Optimization for the BNDM string-search function in
1032 mod_include. [Brian Pane]
1034 *) Fixed the behavior of the XBitHack directive.
1035 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
1037 *) The threaded MPM for Unix has been removed. Use the worker
1038 MPM instead. [various]
1040 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
1041 in logging the error from a failed DNS lookup. [Jeff Trawick]
1043 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
1046 *) Get mod_cgid killed when a MPM exits due to a fatal error.
1049 *) Fix a file descriptor leak in mod_include. When we include a
1050 file, we use a sub-request, but we didn't destroy the sub-request
1051 immediately, instead we waited until the original request was
1052 done. This patch closes the sub-request as soon as the data is
1053 done being generated. [Brian Pane <bpane@pacbell.net>]
1055 *) Allow modules that add sockets to the ap_listeners list to
1056 define the function that should be used to accept on that
1057 socket. Each MPM can define their own function to use for
1058 the accept function with the MPM_ACCEPT_FUNC macro. This
1059 also abstracts out all of the Unix accept error handling
1060 logic, which has become out of synch across Unix MPMs.
1063 *) Fix a bug which would cause the response headers to be omitted
1064 when sending a negotiated ErrorDocument because the required
1065 filters were attached to the wrong request_rec.
1066 [John Sterling <sterling@covalent.net>]
1068 *) Remove commas from the end of the macros that define
1069 directives that are used by MPMs. Prior to this patch,
1070 you would use these macros without commas, which was unlike
1071 the macros for any other directives. Now, the caller provides
1072 the comma rather than the macro providing it. This makes
1073 the macros look more like the rest of the directives.
1074 [Ryan Bloom and Cliff Woolley]
1076 *) Add 'redirect-carefully' environment option to disable sending
1077 redirects under special circumstances. This is helpful for
1078 Microsoft's WebFolders when accessing a directory resource via
1079 DAV methods. [Justin Erenkrantz]
1081 *) Begin to abstract out the underlying transport layer.
1082 The first step is to remove the socket from the conn_rec,
1083 the server now lives in a context that is passed to the
1084 core's input and output filters. This forces us to be very
1085 careful when adding calls that use the socket directly,
1086 because the socket isn't available in most locations.
1089 *) Really reset the MaxClients value in worker and threaded
1090 when the configured value is not a multiple of the number
1091 of threads per child. We said we did previously but we
1092 forgot to. [Jeff Trawick]
1094 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
1096 *) If shared modules are requested and mod_so is not available,
1097 produce a fatal config-time error. [Justin Erenkrantz]
1099 *) Improve http2env's performance by cutting the work it has to
1100 do. [Brian Pane <bpane@pacbell.net>]
1102 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
1103 [Brian Pane <bpane@pacbell.net>]
1105 Changes with Apache 2.0.28
1107 *) Fix infinite loop in mod_cgid.c.
1108 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
1110 *) When no port is given in a "ServerName host" directive, the
1111 server_rec->port is now set to zero, not 80. That allows for
1112 run-time deduction of the correct server port (depending on
1113 SSL/plain, and depending also on the current setting of
1114 UseCanonicalName). This change makes redirections
1115 work, even with https:// connections. As in Apache-1.3, the
1116 connection's actual port number is never used, only the ServerName
1117 setting or the client's Host: setting. Documentation updated
1118 to reflect the change. [Martin Kraemer]
1120 *) Add a '%{note-name}e' argument to mod-headers, which works in
1121 the same way as mod_log_confg. [Ian Holsman]
1123 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
1124 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
1125 MPMs. [Cliff Woolley]
1127 *) Introduce htdbm, a user management utility for db/dbm authorization
1128 databases. [Mladen Turk <mturk@mappingsoft.com>]
1130 *) Optimize usage of strlen and strcat in ap_directory_walk.
1131 [Brian Pane <bpane@pacbell.net>]
1133 Changes with Apache 2.0.27
1135 *) Introduce an Apache mod_ssl initial configuration template
1136 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
1138 *) Fixed a memory leak in the getline parsing code that could
1139 be triggered by arbitrarily large header lines. Requests
1140 from the core input filter for single lines are now limited
1141 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
1143 *) Fix a truncation bug in how we print the port on the Via: header.
1144 The routine that prints the Via: header now takes a length for
1145 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
1147 *) Some syntax errors in mod_mime_magic's magic file can result
1148 in a 500 error, which previously was unlogged. Now we log the
1149 error. [Jeff Trawick]
1151 *) Add the support/checkgid helper app, which checks the run-time
1152 validity of group identifiers usable in the Group directive.
1155 *) Various --enable-so options have been fixed: --enable-so is
1156 treated as "static"; explicit --enable-so=shared issues an error;
1157 and explicit --enable-so fails with error on systems without
1158 APR_HAS_DSO. [Aaron Bannert]
1160 *) Fix a segfault in the core input filter when the client socket
1161 gets disconnected unexpectedly. [Cliff Woolley]
1163 *) Fix the reporting for child processes that die. This removes
1164 all of the non-portable W* macros from Apache.
1165 [Jeff Trawick and Ryan Bloom]
1167 *) Win32: Track and display "Parent Server Generation:" in
1168 mod_status output. The generation will be bumped at
1169 server graceful restart, when the child process exits
1170 by hitting MaxRequestsPerChild or if the child
1171 process exits abnormally. [Bill Stoddard]
1173 *) Win32: Fix problem where MaxRequestsPerChild directive was
1174 not being picked up in favor of the default. Enable
1175 the parent to start up a new child process immediately upon
1176 the old child starting shutdown.
1179 *) Fix some bungling of the remote port in rfc1413.c so that
1180 IdentityCheck retrieves the proper user id instead of failing
1181 and thus always returning "nobody."
1182 [Dick Streefland <Dick.Streefland@xs4all.nl>]
1184 *) Introduced thread saftey for mod_rewrite's internal cache.
1185 [Brian Pane <bpane@pacbell.net>]
1187 *) Simplified mod_env's directives to behave as most directives are
1188 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
1189 directive following that UnsetEnv within the same container.
1190 Also provides a runtime startup warning if a PassEnv configured
1191 environment value is undefined. [William Rowe]
1193 *) The worker MPM is now completely ported to APR's new lock API. It
1194 uses native APR types for thread mutexes, cross-process mutexes,
1195 and condition variables. [Aaron Bannert]
1197 *) Sync up documentation to remove all references to the now deprecated
1198 Port directive. [Justin Erenkrantz]
1200 *) Moved all ldap modules from the core to httpd-ldap sub-project
1203 *) Exit when we can't listen on any of the configured ports. This
1204 is the same behavior as 1.3, and it avoids having the MPMs to
1205 deal with bogus ap_listen_rec structures. [Jeff Trawick]
1207 *) Cleanup the proxy code that creates a request to the origin
1208 server. This change adds an optional hook, which allows modules
1209 to gain control while the request is created if the proxy module
1210 is loaded. The purpose of this hook is to allow modules to add
1211 input and/or output filters to the request to the origin. While
1212 I was at it, I made the core use this hook, so that proxy request
1213 creation uses some of the code from the core. This can still be
1214 greatly improved, but this is a good start. [Ryan Bloom]
1216 Changes with Apache 2.0.26
1218 *) Port the MaxClients changes from the worker MPM to the threaded
1221 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
1222 with the new input filtering system. [Justin Erenkrantz]
1224 *) Introduce the MultiviewsMatch directive, to allow the operator
1225 to be flexible in recognizing Handlers and Filters filename
1226 extensions as part of the Multiviews matching logic, strict with
1227 MultiviewsMatch NegotiatedOnly to accept only filename extentions
1228 that designate negotiated parameters, (content type, charset, etc.)
1229 or MultiviewsAll for the 1.3 behavior of matching any files, even
1230 if they have unregistered extensions. [William Rowe]
1232 *) Fixed the configure script to add a LoadModule directive to
1233 the default httpd.conf for any module that was compiled
1234 as a DSO. [Aaron Bannert <aaron@clove.org>]
1236 *) rewrite mod_ssl input filtering to work with the new input filtering
1237 system. [Justin Erenkrantz]
1239 *) prefork: Don't segfault when we are able to listen on some but
1240 not all of the configured ports. [Jeff Trawick]
1242 *) Build mod_so even if no core modules are built shared.
1243 [Aaron Bannert <aaron@clove.org>]
1245 *) Introduce ap_directory_walk rewrite (with further optimizations
1246 required) to adapt to the ap_process_request_internal() changes.
1247 Optimized so subrequests and redirects now reuse previous section
1248 merges, until we mismatch with the original directory_walk, and
1249 precomputed r->finfo results will cause directory_walk to skip
1250 the most expensive phases of the function. [William Rowe]
1252 *) Allow ApacheMonitor to connect to and control Apache on other
1253 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
1255 *) Remove the Port directive. In it's place, the Listen directive
1256 is now a required directive, which tells Apache what port to
1257 listen on. The ServerName directive has also been extended
1258 to accept an optional port. If the port is specified to the
1259 ServerName, the server will report that port whenever it
1260 reports the port that it is listening on. This change was
1261 made to ease configuration errors that stem from having a Port
1262 directive, and a Listen directive. In that situation, the server
1263 would only listen to the port specified by the Listen command,
1264 which caused a lot of confusion to users. [Ryan Bloom]
1266 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
1267 build, as loadable modules. [William Rowe]
1269 *) Fix --enable-mods-shared processing. If most is specified,
1270 then all modules that can be compiled as shared modules are.
1271 [Aaron Bannert <aaron@clove.org>]
1273 *) Update the mime.types file to map video/vnd.mpegurl to mxu
1274 and add commonly used audio/x-mpegurl for m3u extensions.
1275 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
1277 *) Eliminate the depreciated r->content_language, in favor of the array
1278 r->content_languages introduced many years ago. Module authors must
1279 substantially overhaul their modules, so this needs to be upgraded
1280 if the module still relied on backwards-brokeness. [William Rowe]
1282 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
1285 *) Rewrite the input filtering mechanisms to consolidate and reorganize
1286 code. In short, core_input_filter does something now and
1287 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
1289 *) Update the Win32 build to re-absorb mod_proxy and family.
1292 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
1293 current SDK.) [William Rowe]
1295 *) Some style changes to the code that does ProxyErrorOverride. Fixed
1296 config merge behaviour. [Graham Leggett]
1298 *) Allow support programs to be compiled against a static version
1299 of libapr. This allows the smaller support programs to be
1300 relocated. [Aaron Bannert <aaron@clove.org>]
1302 *) Update the mime.types file to the registered media types as
1303 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
1305 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
1306 number of clients that can connect at the same time, instead of
1307 specifying the maximum number of child processes.
1308 [Aaron Bannert <aaron@clove.org>]
1310 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
1311 be consistent with 1.3. [Justin Erenkrantz]
1313 *) Cache apr_explode_localtime() value for 15 seconds.
1314 [Brian Pane <bpane@pacbell.net>]
1316 *) Fix mod_include to not return ETag or Last-Modified headers.
1317 [Ian Holsman <ianh@cnet.com>]
1319 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
1321 *) Eliminate the wasteful run-time conversion of method names from strings
1322 to numbers in places where the methods are known at compile time.
1323 [Brian Pane <bpane@pacbell.net>]
1325 *) Turn the worker MPM's queue into a LIFO. This may
1326 improve cache-hit performance under some conditions.
1327 [Aaron Bannert <aaron@clove.org>]
1329 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
1330 support it. [Justin Erenkrantz]
1332 *) Cleanup the worker MPM. We no longer re-use transaction
1333 pools. This incurs less overhead than shuffling the pools
1334 around so that they can be re-used. Remove one of the
1335 queue's condition variables. We just redefined the API to
1336 state that you can't try to add more stuff than you allocated
1337 segments for. [Aaron Bannert <aaron@clove.org>]
1339 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
1341 *) Fixed persistent connections when a request contains a body.
1344 *) mod_dav uses a new API to speak to the backend provider for dead
1345 property management. [Greg Stein]
1347 *) Remove the Win32 script-processing exception from mod_cgi, and
1348 roll build_command_line/build_argv_list into a unified, overrideable
1349 ap_cgi_build_command optional function. [William Rowe]
1351 *) Rewrite find_start_sequence to use a better search algorithm
1352 to find the start tag. [Justin Erenkrantz]
1354 *) Fix a seg fault in mod_include. When we are generating an
1355 internal redirect, we must set r->uri to "", not a bogus
1356 string, and not NULL. [Ryan Bloom]
1358 *) Optimized location_walk, so subrequests, redirects and second passes
1359 now reuse previous section merges on a <Location > by <Location >
1360 basis, until we mismatch with the original location_walk.
1363 *) Back out the 1.45 change to util_script.c. This change made
1364 us set the environment variable REQUEST_URI to the redirected
1365 URI, instead of the originally requested URI.
1366 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1368 *) Make mod_include do lazy evaluation of potentially expensive to
1369 compute variables. [Brian Pane <bpane@pacbell.net>]
1371 *) Fix logging of bytes sent for HEAD requests. %b and %B should
1372 log either - or 0, before this patch, they were both logging
1373 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1375 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
1376 than per character. [Brian Pane <bpane@pacbell.net>]
1378 *) Normalize the primary request, redirects and sub-requests to
1379 run the same ap_process_request_internal for consistency in
1380 robustness, behavior and security. [William Rowe]
1382 *) Fix a segfault with mod_include when r->path_info is not set
1383 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
1385 *) Add -X functionality back. This indicates to all MPMs and any other
1386 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
1388 *) Some initial support for the cygwin platform [prefork only].
1389 This is not to be confused with support for the WinNT/Win32
1390 platform, which is the recommended configuration for native
1391 Win32 users. The cygwin platform support is recommended for
1392 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
1394 *) Changed syntax of Set{Input|Output}Filter. The list of filters
1395 must be semicolon delimited (if more than one filter is given.)
1396 The Set{Input|Output}Filter directive now overrides a parent
1397 container's directive (e.g. SetInputFilter in <Directory /web/foo>
1398 will override any SetInputFilter directive in <Directory /web>.)
1399 This new syntax is more consistent with Add{Input|Output}Filter
1400 directives defined in mod_mime. Also cures a bug in prior releases
1401 where the Set{Input|Output}Filter directive would corrupt the
1402 global configuration if the multiple directives were nested.
1405 *) Cured what's ailed mime for quite some time. If an AddSomething
1406 was given in the configuration (Language, Charset, Handler or
1407 Encoding) Apache would set the content type as given by AddType,
1408 but refused to check the mime.types file if AddType wasn't given
1409 for that specific extension. Setting the AddHandler for .html
1410 without setting the AddType text/html html would cause Apache to
1411 use the default content type. [William Rowe]
1413 *) Added some bulletproofing to memory allocation in the LDAP cache
1414 code. [Graham Leggett]
1416 Changes with Apache 2.0.25
1418 *) Move the installed /manual directory out of the /htdocs/ tree, so
1419 that it can be kept more independently from the remaining document
1420 root. The "Alias /manual ..." already allowed for easy projection
1421 into existing private document trees. [Martin Kraemer]
1423 *) Add specified user attributes to the environment when using
1424 mod_auth_ldap. This allows you to use mod_include to embed specified
1425 user attributes in a page like so:
1426 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
1429 *) Fix a performance problem with the worker MPM. We now create
1430 transaction pools once, and re-use them for each connection.
1431 [Aaron Bannert <aaron@clove.org>]
1433 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
1434 of a 'handler' or 'filter', so that any filename extension that does
1435 not contribute to the negotiated metadata can't be served without
1436 an explicit request. E.g., if the .Z extension is associated with
1437 an unzip filter, the user request somefile.Z.html, mod_negotiation
1438 won't serve it. It can serve somefile.Z.html when somefile.Z is
1439 requested, since the .Z extension is explictly requested, if the
1440 .html extension is associated with ContentType text/html.
1443 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
1444 and corresponding AddOutputFilter syntax, to insert one or more
1445 filters by mod_mime filename extension processing.
1448 *) Fix a growing connection pool in core_output_filter() for
1449 keepalive requests. [Jeff Trawick]
1451 *) Moved split_and_pass_pretag_buckets back to being a
1452 macro at Ryans's request. Removed the return from it
1453 by setting and returning a return code instead. Updated
1454 the code to check the return code from the macro and
1455 do the right thing. [Paul J. Reder]
1457 *) Fix a segfault when a numeric value was received for Host:.
1460 *) Add a function ap_remove_input_filter. This is to match
1461 up with ap_remove_output_filter. [Ryan Bloom]
1463 *) Clean up location_walk, so that this step performs a minimum
1464 amount of redundant effort (it must be run twice, but it will no
1465 longer reparse all <Location > blocks when the request uri
1466 hadn't changed.) [William Rowe]
1468 *) Eliminate proxy: (and all other 'special') processing from the
1469 ap_directory_walk() phase. Modules that want to use special
1470 walk logic should refer to the mod_proxy map_to_location example,
1471 with it's proxy_walk and proxysection implementation. This makes
1472 either directory_walk flavor much more legible, since that phase
1473 only runs against real <Directory > blocks.
1476 *) Fix a security problem in mod_include which would allow
1477 an SSI document to be passed to the client unparsed.
1478 [Cliff Woolley, Brian Pane]
1480 *) Introduce the map_to_storage hook, which allows modules to bypass
1481 the directory_walk and file_walk for non-file requests. TRACE
1482 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
1483 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
1486 *) Add the ability for mod_include to add the INCLUDES filter
1487 if the file is configured for the server-parsed handler.
1488 This makes the configuration for .shtml files much easier
1489 to understand, and allows mod_include to honor Apache 1.3
1490 config files. Based on Doug MacEachern's patch to PHP
1491 to do the same thing. [Ryan Bloom]
1493 *) force OpenSSL to ignore process local-caching and to always
1494 get/set/delete sessions using mod_ssl's callbacks
1495 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1496 Geoff Thorpe <geoff@geoffthorpe.net>]
1498 *) Make the worker MPM shutdown and restart cleanly. This also
1499 cleans up some race conditions, and gets the worker using
1500 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
1502 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
1504 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1506 *) Fix for mod_include. Ryan's patch to check error
1507 codes put a return in the wrong place. Also, the
1508 include handler return code wasn't being checked.
1509 I don't like macros with returns, so I converted
1510 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
1511 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1513 *) fix segv in mod_mime if no AddTypes are configured
1514 [John Sterling <sterling@covalent.net>]
1516 *) Enable ssl client authentication at SSL_accept time
1517 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
1519 *) Fix a segfault in mod_include when the original request has no
1520 associated filename (e.g., we're filtering the error document for
1521 a bad URI). [Jeff Trawick]
1523 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
1525 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
1526 of httpd is started and shuts down due to socket conflict. Moving the
1527 call to ap_log_pid solves the problem.
1529 *) Changed the late-1.3 log_config substitution %c to %X, to log the
1530 status of the closed connection, as it conflicts with the far more
1531 common, historical ssl logging directive %...{var}c. [William Rowe]
1533 *) Added the common error/ tree to the build/install targets
1534 (similar to the common icons/ tree) for the multi-language error
1535 messages that Lars committed earlier. [William Rowe]
1537 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
1539 *) Added a default commented-out mod_ldap and mod_auth_ldap
1540 configuration to httpd-std.conf and httpd-win.conf
1543 *) Added documentation for mod_ldap and mod_auth_ldap.
1546 *) Enabled negative caching on attribute comparisons in the LDAP cache.
1547 Fixed a problem where the default cache TTL was set in milliseconds
1548 not microseconds causing the cache to time out almost immediately.
1551 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
1552 module code to follow APR. [Graham Leggett]
1554 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
1555 cleaned up when the connection pool pool is cleaned up.
1558 *) Fix a minor issue with Jeff Trawick's mod_include
1559 patch. Without this patch, the code will just allocate
1560 more bytes in get_combined_directive than are needed.
1563 *) Added the LDAP authentication module mod_auth_ldap.
1564 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1566 *) Added the LDAP cache and connection pooling module mod_ldap.
1567 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
1569 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
1570 by allowing a module to disable itself if its prerequisites are not
1571 met. [Justin Erenkrantz]
1573 Changes with Apache 2.0.24
1575 *) Fix a couple of issues in mod_include when the tag appeared at
1576 offsets near 8192 in the file being parsed. [Jeff Trawick]
1578 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
1579 reached. [Jeff Trawick]
1581 *) Numerous improvements to the Win32 build system. Introduced command line
1582 builds without requiring .mak files for MSVC 6.0 and later versions.
1583 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
1586 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
1587 reporting of uninstalled services and other error conditions, and changed the
1588 default service name to Apache2. [William Rowe]
1590 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
1591 compatibility with existing Apache 1.3 Win32 Apache management utilites.
1592 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
1594 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
1595 [William Rowe, Greg Ames]
1597 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
1598 and RemoveCharset directives. [William Rowe]
1600 *) The Unix MPMs other than perchild now allow child server
1601 processes to use the accept mutex when starting as root and
1602 using SysV sems for the accept mutex. Previously, this
1603 combination would lead to fatal errors in the child server
1604 processes. perchild can't use SysV sems because of security
1605 issues. [Jeff Trawick, Greg Ames]
1607 *) Added Win32 revision stamp resources to all http binaries
1608 (including modules/ and support/ tools.) PR7322 [William Rowe]
1610 *) Fix ap_rvprintf to support more than 4K of data at one time.
1611 [Cody Sherr <csherr@covalent.net>]
1613 *) We have always used the obsolete/deprecated Netscape syntax
1614 for our tracking cookies; now the CookieStyle directive
1615 allows the Webmaster to choose the Netscape, RFC2109, or
1616 RFC2965 format. The new CookieDomain directive allows the
1617 setting of the cookie's Domain= attribute, too. PR #s 5006,
1618 5023, 5920, 6140 [Ken Coar]
1620 *) Tweak server/Makefile so that the rules for generating exports.c
1621 are compatible with make utilities which don't expand wildcards
1622 in a dependency list (e.g., OS/390 make, certain levels of GNU
1623 make). [Jeff Trawick]
1625 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
1627 *) Begin to sanitize the MPM configuration directives. Now, all
1628 MPMs use the same functions for all common MPM directives. This
1629 should make it easier to catch all bugs in these directives once.
1630 [Cody Sherr <csherr@covalent.net>]
1632 *) Close a major resource leak. Every time we had issued a
1633 graceful restart, we leaked a socket descriptor.
1636 *) Fix a problem with the new method code. We need to cast
1637 the 1 to an apr_int64_t or it will be treated as a 32-bit
1638 integer, and it will wrap after being shifted 32 times.
1639 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
1641 *) Fix a bug in mod_expires. Previous to this patch, if you
1642 told mod_expires to add 604800 seconds to the last-modified
1643 time, it actually added 604800 usec's to the last-modified time,
1644 so that when looking at the response it looked like nothing
1645 had been done. The root of the problem was that we always compute
1646 time in usec's, but we ask users to input sec's. This means we
1647 need to convert to usec's before using those values.
1650 *) The worker MPM now handles shutdown and restart requests. It
1651 definitely isn't perfect, but we do stop the servers correctly.
1652 The biggest problem right now is that SIGHUP causes the server to
1653 just die. [Ryan Bloom]
1655 Changes with Apache 2.0.23
1657 *) Use the prefork MPM by default on Unix. [various]
1659 *) Added a systray icon monitor application for Win32.
1660 [Mladen Turk <mturk@mappingsoft.com>]
1662 *) mod_rewrite: Fix the line ending on some non-Unix systems for
1663 messages written to the rewrite log.
1664 [Richard Labennett <rlabenn@us.ibm.com>]
1666 *) All mod_autoindex query parsing is now quietly quashed with the
1667 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
1668 still drops the column sort <a href>'s for the column headers, but
1669 IgnoreClient is required to ignore these Query options entirely.
1672 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
1673 to allow the client to select plain, FancyIndexing or HTMLTable
1674 formatting, V=[0|1] to inhibit or enable version sorting, and
1675 P=pattern to return only specific files. The old Query Arguments
1676 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
1677 as before), and O=A|D for ordering ascending or descending.
1680 *) Fixed an error in mod_include's directive parsing routines which
1681 caused #if, #elif, and #else expressions containing backslashes
1682 to be improperly evaluated. [Cliff Woolley]
1684 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
1685 drop the icon column, SuppressRules to drop the <hr> elements,
1686 and HTMLTable to create rudimentary HTML table listings (implies
1687 FancyIndexing). [William Rowe]
1689 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
1690 from Apache 1.3.15. This is needed for two reasons, first, given
1691 multiple machines within a server farm, ETags and Last-Modified
1692 stamps won't correspond from machine to machine, and second, many
1693 Unixes don't capture changes to the date or time stamp of existing
1694 files, since these don't modify the dirent itself. [William Rowe]
1696 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
1697 and DirectoryWidth options from Apache 1.3.10.
1698 [William Rowe, Ken Coar]
1700 *) Eliminated FancyIndexing directive, deprecated early in Apache
1701 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
1703 *) mod_autoindex now excludes any file names that would result in
1704 an error, other than a success or redirect. Also optimized
1705 the parent directory, always included except in the URI '/'.
1708 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
1709 negotiated index pages, and prevent the server from defaulting
1710 to an autoindex of the directory. mod_negotiation will now die
1711 with a 500 Internal Error if it could match some filenames
1712 (e.g. for mod_dir) but none can be served. mod_negotation now
1713 refuses to serve any file with an extention that mod_mime doesn't
1714 recognize, and wasn't part of the request. [William Rowe]
1716 *) Eliminate mod_cgi's handling of .exe files without the .exe file
1717 extension. This is already handled by multiviews, if the admin
1718 wishes to AddHandler .exe or define a content type handler and
1719 associate .exe files with that content type. Multiviews must be
1720 enabled to allow these to be served. [William Rowe]
1722 *) Speed up the server's response to a spike in incoming workload
1723 or restarts by assigning empty scoreboard slots to new processes
1724 when they are available. [Greg Ames]
1726 *) Add a handler to mod_includes.c. This handler is designed to
1727 implement the XbitHack directive. This can't be done with a
1728 fixup, because we need to check the content-type, which is
1729 only available in the handler phase. [Ryan Bloom]
1731 *) Make the includes filter check return codes from filters lower in
1732 the filter chain. If a lower level filter returns an error, then
1733 the request needs to stop immediately. This allows mod_include to
1734 stop parsing data once a lower filter recognizes an error.
1737 *) Add the ability to extend the methods that Apache understands
1738 and have those methods <limit>able in the httpd.conf. It uses
1739 the same bit mask/shifted offset as the original HTTP methods
1740 such as M_GET or M_POST, but expands the total bits from an int to
1741 an ap_int64_t to handle more bits for new request methods than
1742 an int provides. [Cody Sherr <csherr@covalent.net>]
1744 *) Fix broken mod_mime behavior in merging its arguments. Possible
1745 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
1747 *) Solve many mod_ssl porting issues (too many to detail) with
1748 help from the whole team, but most notably [Ralf S. Engelschall,
1749 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
1750 Doug MacEachern, William Rowe, Cliff Woolley]
1752 *) More stall fixes for the threaded & worker mpm's.
1753 Make mod_status output more accurate. Don't
1754 count workers in processes which aren't actively
1755 serving requests. [Greg Ames]
1757 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
1759 *) Add a single listener/multiple worker MPM. This MPM is
1760 definately not fully correct, but it allows us to solve many
1761 of the problems that exist in the threaded MPM. This is a
1762 modified version of the threaded MPM. [Ryan Bloom]
1764 *) Improve content generation throughout Apache, providing closer
1765 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
1766 Transitional specifications. [William Rowe]
1768 Changes with Apache 2.0.22
1770 *) Fix a problem where the threaded MPM stalls after restarts or
1771 segfaults. Also prevent multiple active processes from using
1772 the same scoreboard slot. [Greg Ames]
1774 *) Apache/Win32 now fills in the service description with Apache's
1775 server version string, including loaded and advertised modules.
1778 *) Improved support for the Win32 build, to recover gracefully from
1779 missing apr or apr-util directories or the awk interpreter,
1780 create the proper cgi-bin examples, including a test-cgi.bat, and
1781 fix the perl shebang line for printenv.pl, when installing from
1782 the build environment. [William Rowe]
1784 *) Fix a segfault in threaded.c caused by passing uninitialized
1785 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
1787 *) Use new APR number conversion functions to reduce CPU consumption
1788 when setting the content length, and in mod_log_config.
1791 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
1792 where HEAD response headers were being repeated twice for
1793 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
1794 problem in the http_header filter was exposed by the recent rewrite
1795 of the content_length filter. [Taketo Kabe, Bill Stoddard]
1797 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
1798 restarts. A garbage pointer to a vhost's server_rec from the
1799 previous generation was being left around under certain
1800 conditions. [Greg Ames]
1802 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
1803 used to appear as '(none', without the closing paren.
1804 [Günter Knauf <eflash@gmx.net>]
1806 *) Improve the exports generating awk script. In the past, we had
1807 work around problems in the awk script by avoiding some #if and
1808 #ifdefs. This has bitten us many times in generating the exports.c
1809 file. This improvement allows corrects the header file parsing.
1810 [Sander Striker <striker@apache.org>]
1812 Changes with Apache 2.0.21
1814 *) Resolve the Win32 htpasswd bug, where a file that existed would be
1815 overwritten, regardless of the -c flag.
1816 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
1818 *) Introduce connection sub-pools into ab. Truncating the lifetime
1819 of these allocations means that ab no longer perpetually grows
1820 its working set, running out of memory on large request attempts.
1823 *) Make scoreboard creation a hook. This allows management
1824 modules to have access to the scoreboard at the time that it is
1825 created, and at every restart request.
1826 [Cody Sherr <csherr@covalent.net>]
1828 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
1829 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
1830 daemon index actually used in the scoreboard. I also
1831 updated the pertinent calls. [Paul J. Reder]
1833 *) Win32: Prevent listening sockets from being inherited by
1834 the Apache child process, CGI scripts, rotatelog process
1835 etc. If the Apache child process segfaults, any processes
1836 that the child started are not reaped. Prior to this fix,
1837 these processes inherited the listening sockets which sometimes
1838 prevented the restarted Apache child process from accepting
1839 connections (ie, the server would hang).
1842 *) Provide vhost and request strings when ExtendedStatus is on.
1845 *) Fix some issues with the pod and prefork: check the pod *after*
1846 processing a connection so that a server processing a time-
1847 consuming request bails out as soon as practical; when the
1848 parent process wakes up a server process via connect(), use an
1849 APR timeout on the connect() so that we don't hang for a long
1850 time if there aren't server processes around to do accept().
1851 [Jeff Trawick, Greg Ames]
1853 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
1854 spends a lot of time in apr_table_get calls. Using the default
1855 httpd.conf, the tables for languages and charsets are somewhat
1856 large, so the time spent scanning them on each request is
1857 significant. Replacing the tables with hash tables provides
1858 a nice speedup. [Brian Pane <bpane@pacbell.net>]
1860 *) Add two functions to allow modules to access random parts of the
1861 scoreboard. This allows modules compiled for one MPM to access the
1862 scoreboard, even if it the server was compiled for another MPM.
1863 [Harrie Hazewinkel <harrie@covalent.net>]
1865 Changes with Apache 2.0.20
1867 *) Fix problem in content-length filter where the filter would
1868 buffer all the output from a CGI before sending any bytes
1869 down the filter stack to the network. This problem would cause
1870 significant memory consumption if the CGIs generated
1871 lots of bytes. [Bill Stoddard]
1873 *) Get non-blocking CGI pipe reads working with the bucket brigades.
1876 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
1879 *) Fix a bug in the threaded MPM that would cause it to kill off all
1880 workers immediately after starting if the number of workers started
1881 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
1883 Changes with Apache 2.0.19
1885 *) Fix problem with threaded MPM. The problem was that if each child
1886 process was busy serving a single long-lived request and the server
1887 was sent a graceful restart signal, the server would stop serving
1888 requests. This would happen because each child process would wait to
1889 die until the last thread was done, and the parent wouldn't spawn any
1890 new children until a process died. Now, the parent looks at the fact
1891 that the children are dying gracefully, and starts new children.
1892 Those new children only start enough threads to compliment the number
1893 of threads in the other child process that shares the same spot in
1894 the scoreboard. In this way, we make sure to never go over
1895 MaxClients. [Ryan Bloom]
1897 *) modified mod_negotiation and mod_autoindex to speed up by almost a
1898 factor of two on apr_dir_read()-enhanced platforms, such as Win32
1899 and OS2, by calling ap_sub_request_lookup_dirent() with the results
1900 already provided by apr_dir_read(). [William Rowe]
1902 *) mod_file_cache is now more robust to filtering and serves requests
1903 slightly more efficiently. [Cliff Woolley]
1905 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
1906 Module was calling ap_rwrite() followed by ap_rflush() but the
1907 served content was not being displayed in the browser. Inspection
1908 of the output stream revealed that the first data chunk was
1909 missing the trailing CRLF required by the RFC. [Bill Stoddard]
1911 *) apxs no longer generates ap_send_http_header() in the example handler
1913 *) Fix an ab problem which could cause a divide-by-zero exception
1914 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
1915 [Ian Holsman <ianh@cnet.com>]
1917 *) Solve case-insensitive platforms' confusion about negotiated
1918 filenames, allowing files of differnt case to match in choosing
1919 the document to serve. [William Rowe]
1921 *) Fix brokenness when ThreadsPerChild is higher than the built-in
1922 limit. We left ap_threads_per_child at the higher value which
1923 led to segfaults when doing certain scoreboard operations.
1926 *) Fix seg faults and/or missing output from mod_include. The
1927 default_handler was using the subrequest pool for files and
1928 MMAPs, even though the associated APR structures typically
1929 live longer than the subrequest. [Greg Ames]
1931 *) Extend mod_setenvif to support specifying regular expressions
1932 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
1933 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
1934 will cause HAVE_TS to be set if any of the request headers begins
1935 with "TS" and has a value that begins with any character in the
1936 set [a-z]. [Bill Stoddard]
1938 *) httpd children now re-bind themselves to a random CPU on
1939 multiprocessor systems on AIX via bindprocessor() in 2.0.
1940 [Victor J. Orlikowski]
1942 *) Fix htdigest. It would go into a loop in getline when adding
1943 a second user. [Bill Stoddard]
1945 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
1947 *) Automatically generate httpd.exp for AIX.
1948 DSOs now work again on AIX in 2.0
1949 [Victor J. Orlikowski]
1951 *) Add a new request hook, error_log. This phase allows modules
1952 to act on the error log string _after_ it has been written
1953 to the error log. The goal for this hook is to allow monitoring
1954 modules to send the error string to the monitoring agent.
1957 *) Modify mod_echo to make it use filters for input and output.
1958 [Ryan Morgan <rmorgan@covalent.net>]
1960 *) Extend mod_headers to support conditional driven Header
1961 add, append and set. Use SetEnvIf to set an envar and conditionally
1962 add/append/set headers based on this envar thusly:
1964 SetEnvIf TSMyHeader value HAVE_TSMyHeader
1965 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
1967 If the request contains header "TSMyHeader: value" then header
1968 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
1971 *) Extend mod_headers to support using format specifiers on Header
1972 add, append and set header values. Two format specifiers are supported:
1974 %t - reports, in UTC microseconds since the epoch, when the
1975 request was received.
1977 %D - reports the time, in microseconds, between when the request was
1978 received and the response sent.
1981 Header add MyHeader "This request served in %D microseconds. %t"
1983 results in a header being added to the response that looks like this:
1985 MyHeader: This request served in D=5438 microseconds. t=991424704447256
1989 *) Fix reset_filter(). We need to be careful how we remove filters.
1990 If we set r->output_filters to NULL, we also have to reset the
1991 connection's filters. [John Sterling]
1993 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
1995 *) Add a check to ap_die() to make sure the filter stack is sane and
1996 contains the correct basic filters when an error occurs. This fixes
1997 a problem where headers are not being sent on error. [John Sterling]
1999 *) New Header directive 'echo' option. "Header echo regex" will
2000 cause any headers received on the request that match regex to be
2001 echoed to (included in) the response headers.
2004 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
2005 This prevented the inclusion of apr_compat.h. PR #7773
2006 [Oleg Broytmann <phd@phd.pp.ru>]
2008 *) Moved util_uri to the apr-util library. This required a bunch of
2009 apr_name changes for the uri utility functions. [Justin Erenkrantz]
2011 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
2012 insert_filter phase so that other filters are not bypassed by default.
2015 *) Reimplement mod_headers as an output filter. mod_headers can now
2016 add custom headers to inbound requests using the RequestHeader directive
2017 and to responses using the same old Header directive. [Graham Leggett]
2019 Changes with Apache 2.0.18
2021 *) Fix command-line processing so that if a bad argument is specified
2022 Apache will exit. [Jeff Trawick]
2024 *) Change the make targets and rules to be consistent in all of the
2025 Apache-owned source trees. [Roy Fielding]
2027 *) Fix processing of the TRACE method. Previously we passed bogus
2028 parms to form_header_field() and it overlaid some vhost structures,
2029 resulting in a segfault in check_hostalias().
2030 [Greg Ames, Jeff Trawick]
2032 *) Win32: Add support for reliable piped logs. If the logging process
2033 goes down, Apache will automatically restart it. This function has
2034 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
2037 *) Do not start piped log processes during the config file
2038 preflight. This change also circumvents a problem on
2039 Windows where the rotatelog processes created during preflight
2040 was not getting cleaned up properly.
2043 *) add "Request Phase Participation" info to mod_info
2046 *) Make first phase changes to the scoreboard data structures in
2047 preparation for the rewriting of the scoreboard per my posted
2048 design notes. [Paul J. Reder]
2050 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
2051 and apr-util, allow it to be overridden by the configure command-line
2052 (default="--silent") and introduce LT_LDFLAGS to replace what we were
2053 formerly abusing as LTFLAGS. [Roy Fielding]
2055 *) Clean up the reporting of incorrect closing container tags.
2056 [Barrie Slaymaker <barries@slaysys.com>]
2058 *) Simplify the configure process by moving all libtool stuff to APR
2059 and moving hints.m4 inline. [Roy Fielding]
2061 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
2062 of functions used by mod_proxy for export in the DLL
2063 [Ian Holsman <IanH@cnet.com>]
2065 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
2066 request body from its stdin but no reqest body is being written to
2067 the cgi. [Jeff Trawick]
2069 *) mod_log_config: %c connection status incorrectly logged
2070 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
2073 *) Get mod_cern_meta working under Windows
2076 *) Create Files, and thus MMAPs, out of the request pool, not the
2077 connection pool. This solves a small resource leak that had us
2078 not closing files until a connection was closed. In order to do
2079 this, at the end of the core_output_filter, we loop through the
2080 brigade and convert any data we have into a single HEAP bucket
2081 that we know will survive clearing the request_rec.
2082 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
2085 *) Completely revamp configure so that it preserves the standard make
2086 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
2087 the configure additions to EXTRA_* variables. Also, allow the user
2088 to specify NOTEST_* values for all of the above, which eliminates the
2089 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
2090 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
2091 avoid pointless duplications. Fix the order in which flags are given
2092 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
2093 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
2094 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
2095 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
2097 *) Get mod_tls to compile/work better on Windows. PR #7612
2098 [Bernhard Schrenk <b.schrenk@improx.com>]
2100 *) Fix shutdown/restart hangs in the threaded MPM.
2101 [Jeff Trawick, Greg Ames, Ryan Bloom]
2103 *) Removed the keptalive boolean from conn_rec because it is now only
2104 used by a single routine and can be replaced by a local variable.
2105 [Greg Stein, Ryan Bloom, Roy Fielding]
2107 *) Patch prefork to put enough of the signal processing back in so that
2108 signals are all handled properly now. The previous patch fixed the
2109 deadlock race condition, but broke the user directed signal handling.
2110 This fixes it to work the way it did before my previous prefork patch
2111 (primarily, SIGTERM is now working).
2113 *) Change how input filters decide how much data is returned to the
2114 higher filter. We used to use a field in the conn_rec, with this
2115 change, we use an argument to ap_get_brigade to determine how much
2116 data is retrieved. [Ryan Bloom]
2118 *) Fix seg fault at start-up introduced by Ryan's change to enable
2119 modules to specify their own logging tags. mod_log_config
2120 registers an optional function, ap_register_log_handler().
2121 ap_register_log_handler() was being called by http_core before
2122 the directive hash table was created. This patch creates the
2123 directive hash table before ap_register_log_handler() is
2124 registered as an optional function.
2125 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2127 *) Add ap_set_int_slot() function
2128 [John K. Sterling <sterling@covalent.net>]
2130 *) Under certain circumstances, Apache did not supply the
2131 right response headers when requiring authentication.
2132 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
2133 (This is a port of the change that went into Apache 1.3.19.)
2135 *) Allow modules to specify their own logging tags. This basically
2136 allows a module to tell mod_log_config that when %x is encountered
2137 a specific function should be called. Currently, x can be any single
2138 character. It may be more useful to make this a string at some point.
2141 Changes with Apache 2.0.17
2143 *) If a higher-level filter handles the the byterange aspects of a
2144 request, then the byterange filter should not try to redo the
2145 work. The most common case of this happening, is a byterange
2146 request going through the proxy, and the origin server handles
2147 the byterange request. The proxy should ignore it.
2148 [Graham Leggett <minfrin@sharp.fm>]
2150 *) Changed the threaded mpm to have child_main join to each of the
2151 worker threads to make sure the kids are all gone before child_main
2152 exits after a signal (cleanup from perform_idle_server_maintenance).
2153 This is an extension of Ryans recent commit to make the child_main
2156 *) Add more options to the ap_mpm_query function. This also allows MPMs to
2157 report if their threads are dynamic or static. Finally, this also
2158 implements a new API, ap_show_mpm, which returns the MPM that was
2159 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
2161 *) Do not install the binaries from the support directory twice.
2162 [jun-ichiro hagino <itojun@iijlab.net>]
2164 *) The ap_f* functions should flush data to the filter that is passed
2165 in, not the the filter after the one passed in.
2166 [Ryan Morgan <rmorgan@covalent.net>]
2168 *) Make ab work again by changing its native types to apr types and formats.
2169 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2171 *) Move the byterange filter and all of the supporting functions back
2172 to the HTTP module. The byterange filter turned out to be very
2173 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
2175 *) Make clean, distclean, and extraclean consistently according to the
2176 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
2178 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
2179 This may have been causing problems stopping processes in the threaded
2182 *) Fix content-length in mod_negotiation to a long int representation.
2185 *) Remove BindAddress from the default config file.
2186 [giles@nemeton.com.au]
2188 *) Allow module authors to add a module to their Apache build using
2189 --with-module, without re-running buildconf. The syntax is:
2190 --with-module=module_type:/path/to/module.c
2191 The configure script will copy the module.c file to
2192 modules/module_type, and it will be added to the relevant Makefiles.
2193 currently, this only works for static modules. [Ryan Bloom]
2195 *) Changes required to make prefork clean up idle children properly.
2196 There was a window during which a starting worker deadlocks when
2197 an idle cleanup arrives before it completes init. Apache then keeps
2198 trying to cleanup the same deadlocked worker forever (until higher
2199 pids come along, but it still will never reduce below the deadlocked
2200 pid). Thus the number of children would not reduce to the correct
2201 idle level. [Paul J. Reder]
2203 Changes with Apache 2.0.16
2205 *) Change the default installation directory to /usr/local/apache2,
2206 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
2208 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
2211 *) Get MaxRequestsPerChild working with the Windows MPM.
2214 *) Make generic hooks to work, with mod_generic_hook_import/export
2215 experimental modules. [Ben Laurie, Will Rowe]
2217 *) Fix segfaults for configuration file syntax errors such as
2218 "<Directory>" followed by "</Directory" and
2219 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
2221 *) Cleanup the --enable-layout option of configure. This makes
2222 us use a consistent location for the config.layout file, and it
2223 makes configure more portable.
2224 [jun-ichiro hagino <itojun@iijlab.net>]
2226 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
2227 csv/gnuplot format, rudimentary ssl support and various other tweaks
2228 to make results more true to what is measured. The upshot of this it
2229 turns out that 'ab' has often underreported the true performance of
2230 apache. Often by a order of magnitude :-) See talk/paper of Sander
2231 Temme at April ApacheCon 2001 for details.
2232 [Dirk-Willem van Gulik]
2234 *) Clean up mod_cgid's temporary request pool. Besides fixing a
2235 storage leak this ensures that some unnecessary pipes are closed.
2238 *) Performance: Add quick_handler hook. This hook is called at the
2239 very beginning of the request processing before location_walk,
2240 translate_name, etc. This hook is useful for URI keyed content
2241 caches like Mike Abbott's Quick Shortcut Cache.
2244 *) top_module global variable renamed to ap_top_module [Perl]
2246 *) Move ap_set_last_modified to the core. This is a potentially
2247 controversial change, because this is kind of HTTP specific. However
2248 many protocols should be able to take advantage of this kind of
2249 information. I expect that headers will need one more layer of
2250 indirection for multi-protocol work, but this is a small step in
2251 the right direction. [Ryan Bloom]
2253 *) Enable mod_status by default. This matches what Apache 1.3 does.
2256 *) Add a ScriptSock directive to the default config file. This is
2257 only enabled when mod_cgid is used.
2258 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2260 Changes with Apache 2.0.15
2262 *) Untangled the buildconf script and eliminated the need for build's
2263 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
2264 libtool muck that is now under srclib/apr/build. [Roy Fielding]
2266 *) Win32: Don't accept more connections than we have worker threads
2270 *) Fix bug in the Unix threaded.c MPM that allowed child processes
2271 to fork() new child processes.
2274 *) Fix a major security problem with double-reverse lookup checking.
2275 Previously, a client connecting over IPv4 would not be matched
2276 properly when the server had an IPv6 listening socket. PR #7407
2277 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
2279 *) Change the way the beos MPM handles polling to allow it to stop and
2280 restart. Problem was the sockets being polled were being reset by
2281 the select call, so once it had accepted a connection it was no
2282 longer listening on the UDP socket we use for shutdown instructions.
2283 APR needs to be altered, patch on it's way. [David Reid]
2285 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
2286 on error exit from ap_getline(). Some other code got upset because
2287 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
2289 *) Handle ap_discard_request_body() being called more than once.
2290 [Greg Ames, Jeff Trawick]
2292 *) Get rid of an inadvertent close of file descriptor 2 in
2293 mod_mime_magic. [Greg Ames, Jeff Trawick]
2295 *) Add a hook, create_request. This hook allows modules to modify
2296 a request while it is being created. This hook is called for all
2297 request_rec's, main request, sub request, and internal redirect.
2298 When this hook is called, the the r->main, r->prev, r->next
2299 pointers have been set, so modules can determine what kind of
2300 request this is. [Ryan Bloom]
2302 *) Cleanup the build process a bit more. The Apache configure
2303 script no longer creates its own helper scripts, it just
2305 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
2307 *) Stop the forced downgrade of the connection to HTTP/1.0 for
2308 proxy requests. [Graham Leggett]
2310 *) Avoid using sscanf to determine the HTTP protocol number in
2311 the common case because sscanf is a performance hog. From
2312 Mike Abbot's Accelerating Apache patch number 6.
2313 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
2315 *) Fix a security exposure in mod_access. Previously when IPv6
2316 listening sockets were used, allow/deny-from-IPv4-address rules
2317 were not evaluated properly (PR #7407). Also, add the ability to
2318 specify IPv6 address strings with optional prefix length on Allow
2319 and Deny. [Jeff Trawick]
2321 *) Enhance rotatelogs so that a UTC offset can be specified, and
2322 the logfile name can be formatted using strftime(3). (Brought
2323 forward from 1.3.) [Ken Coar]
2325 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
2326 DuplicateHandle on an IOCompletionPort (a practice which
2327 MS "discourages"). The new model does not rely on associating
2328 the completion port with the listening sockets, thus the
2329 completion port can be completely managed within the child
2330 process. A dedicated thread accepts connections off the network,
2331 then calls PostQueuedCompletionStatus() to wake up worker
2332 threads blocked on the completion port.
2335 *) Bring forward the --suexec-umask option which allows the
2336 builder to preset the umask for suexec processes. [Ken Coar]
2338 *) Add a -V flag to suexec, which causes it to display the
2339 compile-time settings with which it was built. (Only
2340 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
2342 *) Mod_include should always unset the content-length if the file is
2343 going to be passed through send_parsed_content. There is no to
2344 determine if the content will change before actually scanning the
2345 entire content. It is far safer to just remove the C-L as long
2346 as we are scanning it. [Ryan Bloom]
2348 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
2349 request and not Proxy-Authenticate.
2350 [Graham Leggett <minfrin@sharp.fm>]
2352 Changes with Apache 2.0.14
2354 *) Fix content-length computation. We ONLY compute a content-length if
2355 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
2356 or we already have all the data. [Ryan Bloom]
2358 *) Report unbounded containers in the config file. Previously, a typo
2359 in the </container> directive could result in the rest of the config
2360 file being silently ignored, with undesired defaults used.
2363 *) Make the old_write filter use the ap_f* functions for the buffering.
2366 *) Move more code from the http module into the core server. This
2367 is core code, basically the default handler, the default input
2368 and output filters, and all of the core configuration directives.
2369 All of this code is required in order for the server to work, with or
2370 without HTTP. The server is closer to working without the HTTP
2371 module, although there is still more to do. [Ryan Bloom]
2373 *) Fix a number of SGI compile warnings throughout the server. Fix some
2374 bad parameters to apr_bucket_read(). Fix a bad statement in
2375 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
2376 consistently; we were mixing apr_time_t and time_t in invalid ways
2377 before. In load_file(), call apr_dso_error() instead of
2378 apr_strerror() so that we get a more specific string on some platforms.
2379 PR #6980 [Jeff Trawick]
2381 *) Allow modules to query the MPM about it's execution profile. This
2382 query API can and should be extended in the future, but for now,
2383 max_daemons, and threading or forking is a very good start.
2384 [Jon Travis <jtravis@covalent.net>]
2386 *) Modify mod_include to send blocks of data no larger than 9k.
2387 Without this, mod_include will wait until the whole file is parsed,
2388 or the first tag is found to send any data to the client.
2389 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2391 *) Fix mod_info, so that <Directory> and <Location> directives are
2392 not displayed twice when displaying the current configuration.
2393 [Ryan Morgan <rmorgan@covalent.net>]
2395 *) Add config directives to override DEFAULT_ERROR_MSG and
2396 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
2397 [Dan Rench <drench@xnet.com>]
2399 *) Get mod_info building and loading on Win32. [William Rowe]
2401 *) Begin to move protocol independant functions out of mod_http. The goal
2402 is to have only functions that are HTTP specific in the http directory.
2405 Changes with Apache 2.0.13
2407 *) Don't assume that there will always be multiple calls to the byterange
2408 filter. It is possible that we will need to do byteranges with only
2409 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
2411 *) Move the error_bucket definition from the http module to the
2412 core server. Every protocol will need this ability, not just
2415 Changes with Apache 2.0.12
2417 *) Modify mod_file_cache to save pre-formatted strings for
2418 content-length and last-modified headers for performance.
2419 [Mike Abbot <mja@trudge.engr.sgi.com>]
2421 *) Namespace protect IOBUFSIZ since it is exposed in the API.
2422 [Jon Travis <jtravis@covalent.net>]
2424 *) Use "Basic" authentication instead of "basic" in ab, as the spec
2425 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
2427 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
2428 without ever filling it out. This fixes PR 7271.
2429 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
2430 Cliff Woolley <cliffwoolley@yahoo.com>]
2432 *) Add a couple of GCC attribute tags to printf style functions.
2433 [Jon Travis <jtravis@covalent.net>]
2435 *) Add the correct language tag for interoperation with the Taiwanese
2436 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
2438 *) Migrate the perchild MPM to use the new apr signal child, and
2439 APR thread functions. [Ryan Bloom]
2441 *) Close one copy of the CGI's stdout before creating the new process.
2442 The CGI will still have stdout, because we have already dup'ed it.
2443 This keeps Apache from waiting forever to send the results of a CGI
2444 process that has forked a long-lived child process.
2445 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
2447 *) Remove the rest of the pthreads functions from the threaded MPM.
2448 This requires the APR support for a signal thread that was just
2451 *) Make mod_dir use a fixup for sending a redirect to the browser.
2452 Before this, we were using a handler, which doesn't make much
2453 sense, because the handler wasn't generating any data, it would
2454 either return a redirect error code, or DECLINED. This fits the
2455 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
2457 *) Make the threaded MPM use APR threads instead of pthreads.
2460 *) Get mod_tls to the point where it actually appears to work in all cases.
2463 *) implement --enable-modules and --enable-mods-shared for "all" and
2464 "most". [Greg Stein]
2466 *) Move the threaded MPM to use APR locks instead of pthread locks.
2469 *) Rename mpmt_pthread to threaded. This is more in line with the
2470 fact that mpmt_pthread shouldn't be using pthreads directly, and
2471 it is a smaller name that doesn't tie into anything.
2474 *) Rename the module structures so that the exported symbol matches
2475 the file name, and it is easier to automate the installation
2476 process (generating LoadModule directives from the module filenames).
2479 *) Remove the coalesce filter. With the ap_f* functions, this filter
2480 is no longer needed. [Ryan Bloom]
2482 Changes with Apache 2.0.11
2484 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
2485 added feature of allowing a uid/gid per child process. If no
2486 uid/gid is specified, then Perchild behaves exactly like dexter.
2489 *) Get perchild building again. [Ryan Bloom]
2491 *) Don't disable threads just because we are using the prefork MPM.
2492 If somebody wants to compile without threads, they must now add
2493 --disable-threads to the configure command line. [Ryan Bloom]
2495 *) Begin to move the calls to update_child_status into common code, so
2496 that each individual MPM does not need to update the scoreboard itself.
2499 *) Allow mod_tls to compile under Unix boxes where openssl has been
2500 installed to the system include files.
2501 [Gomez Henri <new-httpd@slib.fr>]
2503 *) Cleanup the mod_tls configure process. This should remove any need
2504 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
2505 configure doesn't check that yet. [Ryan Bloom]
2507 *) Add a very early prototype of SSL support (in mod_tls.c). It is
2508 vital that you read modules/tls/README before attempting to build
2511 *) Fix a potential seg fault on all platforms. David Reid fixed this
2512 on BEOS, but the problem could happen anywhere, so we don't want
2513 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
2515 *) Add new LogFormat directive, %D, to log time it takes to serve a
2516 request in microseconds. [Bill Stoddard]
2518 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
2519 SetOutputFilter. This corresponds nicely with the other Set
2520 directives, which operate on containers while the Add* directives
2521 tend to work directly on extensions. [Ryan Bloom]
2523 *) Cleanup the header handling a bit. This uses the apr_brigade_*
2524 functions for the buffering so that we don't need to compute
2525 the length of the headers before we actually create the header
2526 buffer. [Ryan Bloom]
2528 *) Allow filters to buffer data using the ap_f* functions. These have
2529 become macros that resolve directly to apr_brigade_*.
2532 *) Get the Unix MPM's to do a graceful restart again. If we are going
2533 to register a cleanup with ap_cleanup_scoreboard, then we have to
2534 kill the cleanup with the same function, and that function can't be
2535 static. [Ryan Bloom]
2537 *) Install all required header files. Without these, it was not
2538 possible to compile some modules outside of the server.
2541 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
2542 forward from 1.3 to 2.0, we missed a single line, which broke regex
2543 aliases. [Ryan Bloom]
2545 *) We have a poor abstraction in the protocol. This is a temporary
2546 hack to fix the bug, but it will need to be fixed for real. If
2547 we find an error while sending out a custom error response, we back
2548 up to the first non-OK request and send the data. Then, when we send
2549 the EOS from finalize_request_protocol, we go to the last request,
2550 to ensure that we aren't sending an EOS to a request that has already
2551 received one. Because the data is sent on a different request than
2552 the EOS, the error text never gets sent down the filter stack. This
2553 fixes the problem by finding the last request, and sending the data
2554 with that request. [Ryan Bloom]
2556 *) Make the server status page show the correct restart time, and
2557 thus the proper uptime. [Ryan Bloom]
2559 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
2560 should reduce the amount of duplicate code that is required to
2561 create CGI processes.
2562 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2564 *) ap_new_connection() closes the socket and returns NULL if a socket
2565 call fails. Usually this is due to a connection which has been
2566 reset. [Jeff Trawick]
2568 *) Move the Apache version information out of httpd.h and into release.h.
2569 This is in preparation for the first tag with the new tag and release
2570 system. [Ryan Bloom]
2572 *) Begin restructuring scoreboard code to enable adding back in
2573 the ability to use IPC other than shared memory.
2574 Get mod_status working on Windows again. [Bill Stoddard]
2576 *) Make mod_status work with 2.0. This will work for prefork,
2577 mpmt_pthread, and dexter. [Ryan Bloom]
2579 *) Correct a typo in httpd.conf.
2580 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
2582 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
2584 *) Get the correct IP address if ServerName isn't set and we can't
2585 find a fully-qualified domain name at startup.
2586 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
2588 *) Make mod_cgid work with SuExec. [Ryan Bloom]
2590 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
2591 'extra' stat's for user/group since they should never occur, and now
2592 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
2593 volumes. [William Rowe]
2595 *) Adopt apr features to simplify mod_includes. This changes the
2596 behavior of the USER_NAME variable, unknown uid's are now reported
2597 as USER_NAME="<unknown>" rather than the old user#000 result.
2598 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
2600 *) Adopt apr features for simplifing mod_userdir, and accept the new
2601 Win32/OS2 exceptions without hiccuping. [William Rowe]
2603 *) Replace configure --with-optim option by using and saving the
2604 environment variable OPTIM instead. This is needed because configure
2605 options do not support multiple flags separated by spaces.
2608 *) Fix some byterange handling. If we get a byte range that looks like
2609 "-999999" where that is past the end of the file, we should return
2610 a PARTIAL CONTENT status code, and return the whole file as one big
2611 byterange. This matches the 1.3 handling now. [Ryan Bloom]
2613 *) Make the error bucket a real meta-data bucket. This means that the
2614 bucket length is 0, and a read returns NULL data. If one of these
2615 buckets is passed down after the headers are sent, this data will
2616 just be ignored. [Greg Stein]
2618 *) The prefork MPM wasn't killing child processes correctly if a restart
2619 signal was received while the process was serving a request. The child
2620 process would become the equivalent of a second parent process. If
2621 we break out of the accept loop, then we need to do die after cleaning
2622 up after ourselves. [Ryan Bloom]
2624 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
2625 restarts. [Ryan Bloom]
2627 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
2628 the most optimal APR_FINFO_wanted bits. This spares Win32 from
2629 performing very expensive owner, group and permission lookups
2630 and allows the server to function until these apr_finfo_t fields
2631 are implemented under Win32. [William Rowe]
2633 *) Support for typedsafe optional functions - that is functions exported by
2634 optional modules, which, therefore, may or may not be present, depending
2635 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
2636 for sample code. [Ben Laurie]
2638 *) filters can now report an HTTP error to the server. This is done
2639 by sending a brigade where the first bucket is an error_bucket.
2640 This bucket is a simple bucket that stores an HTTP error and
2641 a string. Currently the string is not used, but it may be needed
2642 to output an error log. The http_header_filter will find this
2643 bucket, and output the error text, and then return
2644 AP_FILTER_ERROR, which informs the server that the error web page
2645 has already been sent. [Ryan Bloom]
2647 *) If we get an error, then we should remove all filters except for
2648 those critical to serving a web page. This fixes a bug, where
2649 error pages were going through the byterange filter, even though
2650 that made no sense. [Ryan Bloom]
2652 *) Relax the syntax checking of Host: headers in order to support
2653 iDNS. PR#6635 [Tony Finch]
2655 *) Cleanup the byterange filter to use the apr_brigade_partition
2656 and apr_bucket_copy functions. This removes a lot of very messy
2657 code, and hopefully makes this filter more stable.
2660 *) Remove AddModule and ClearModuleList directives. Both of these
2661 directives were used to ensure that modules could be enabled
2662 in the correct order. That requirement is now gone, because
2663 we use hooks to ensure that modules are in the correct order.
2666 *) When SuExec is specified, we need to add it to the list of
2667 targets to be built. If we don't, then any changes to the
2668 configuration won't affect SuExec, unless 'make suexec' is
2669 specifically run. [Ryan Bloom]
2671 *) Cleaned out open_file from mod_file_cache, as apr now accepts
2672 the APR_XTHREAD argument to open a file for consumption by
2673 parallel threads on win32. [William Rowe]
2675 *) Correct a bug in determining when we follow symlinks. The code
2676 expected a stat -1 result, not an apr_status_t positive error.
2677 Also check if the APR_FINFO_USER fields are valid before we
2678 follow the link. [William Rowe]
2680 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
2681 mpm_common.c. These functions are only valid on some platforms,
2682 so they should not be in the main-line code. [Ryan Bloom]
2684 *) Remove ap_chdir_file(). This function is not thread-safe,
2685 and nobody is currently using it. [Ryan Bloom]
2687 *) Do not try to run make depend if there are no .c files in the
2688 current directory, doing so makes `make depend` fail.
2691 *) Update highperformance.conf to work with either prefork or
2692 pthreads mpms. [Greg Ames]
2694 *) Stop checking to see if this is a pipelined request if we know
2695 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
2696 This keeps us from making an extra read call when serving a 1.0
2697 request. [Ryan Bloom and Greg Stein]
2699 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
2700 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
2701 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
2703 *) Fix the RFC number mentioned when complaining about a missing
2704 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
2706 *) Fix an endless loop in ab which occurred when ab was posting
2707 and the server dropped the connection unexpectedly.
2710 *) Fix a segfault while handling request bodies in ap_http_filter().
2711 This problem has been seen with mod_dav usage as well as with
2712 requests where the body was just being discarded. [Jeff Trawick]
2714 *) Some adjustment on the handling and automatic setting (via
2715 hints.m4) of various compilation flags (eg: CFLAGS). Also,
2716 add the capability to specify flags (NOTEST_CFLAGS and
2717 NOTEST_LDFLAGS) which are used to compile Apache, but
2718 not used during the configuration process. Useful for
2719 flags like "-Werror". [Jim Jagielski]
2721 *) Stop using environment variables to force debug mode or
2722 no detach. We now use the -D command line argument to
2723 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
2724 [Greg Stein, Ryan Bloom]
2726 *) Change handlers to use hooks. [Ben Laurie]
2728 *) Stop returning copies of filenames from both apr_file_t and
2729 apr_dir_t. We pstrdup the filenames that we store in the
2730 actual structures, so we don't need to pstrdup the strings again.
2733 *) mod_cgi: Fix some problems where the wrong error value was being
2734 traced. [Jeff Trawick]
2736 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
2739 *) Add generic hooks. [Ben Laurie]
2741 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
2743 *) Fix a segfault caused by mod_ext_filter when the external filter
2744 program does not exist. [Jeff Trawick]
2746 *) Fix an output truncation error when on an HTTP >= 1.0 request an
2747 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
2748 was served through mod_charset_lite (or anything else that would
2749 create a transient bucket in this size range). ap_bucket_make_heap()
2750 silently failed (fixed), transient_setaside() discovered it, but
2751 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
2753 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
2754 is that some browsers send extra lines at the end of POST requests, and
2755 we don't want to delay sending data back to the user just because the
2756 browser isn't well behaved. [Ryan Bloom]
2758 *) Get SuEXEC working again. We can't send absolute paths to suExec
2759 because it refuses to execute those programs. SuEXEC also wasn't
2760 always recognizing configuration changes made using the autoconf
2763 *) Allow the buildconf process to find the config.m4 files in the correct
2764 order. Basically, we can now name config.m4 files as config\d\d.m4,
2765 and we will sort them correctly when inserting them into the build
2766 process. [Ryan Bloom]
2768 *) Get mod_cgid to use apr calls for creating the actual CGI process.
2769 This also allows mod_cgid to use ap_os_create_priviledged_process,
2770 thus allowing for SuExec execution from mod_cgid. Currently, we do
2771 not support everything that standard SuExec supports, but at least
2772 it works minimally now. [Ryan Bloom]
2774 *) Allow SuExec to be configured from the ./configure command line.
2777 *) Update some of the docs in README and INSTALL to reflect some of
2778 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
2780 *) If we get EAGAIN returned from the call to apr_sendfile, then we
2781 need to call sendfile again. This gets us serving large files
2782 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
2784 *) Get the support programs building cleanly again.
2785 [Cliff Woolley <cliffwoolley@yahoo.com>]
2787 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
2788 current directory logic now backs up over bin/ to determine the
2789 server root from the Apache.exe path.
2791 *) Apache/Win32 now follows the standard conventions of mod_foo.so
2792 loadable modules, dynamic libs are all named libfoo.dll, and the
2793 makefile.win populates the include, lib and libexec directories.
2795 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
2796 Apache gets IPv6 listening sockets by default. Additionally, the
2797 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
2798 numeric address strings (e.g., "Listen [fe80::1]:8080").
2801 *) Modify the install directory layout. Modules are now installed in
2802 modules/. Shared libraries should be installed in libraries/, but
2803 we don't have any of those on Unix yet. All install directories
2804 are modifyable at configure time. [Ryan Bloom]
2806 *) Install all header files in the same directory on Unix. [Ryan Bloom]
2808 *) Get the functions in server/linked into the server, regardless of
2809 which modules linked into the server. This uses the same hack
2810 for Apache that we use for APR and apr-util to ensure all of the
2811 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
2812 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
2813 the scripts a bit easier.
2816 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
2817 on the query, and remove IPv4 dependencies. [Jeff Trawick]
2819 *) Get all of the auth modules to the point that they will install and
2820 be loadable into the server. Our new build/install mechanism expects
2821 that all modules will have a common name format. The auth modules
2822 didn't use that format, so we didn't install them properly.
2825 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
2826 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
2828 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
2830 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
2831 after the end of the response. [Ryan Bloom]
2833 *) Get byterange requests working with responses that do not have a
2834 content-length. Because of the way byterange requests work, we have to
2835 have all of the data before we can actually do the byterange, so we
2836 can compute the content-length in the byterange filter.
2839 *) Get exe CGI's working again on Windows.
2842 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
2843 they keep track of whether or not their post config hook has been
2844 called before. Instead of a static variable (which is replaced when
2845 the DSO is loaded a second time), use userdata in the process pool.
2848 Changes with Apache 2.0a9
2850 *) Win32 now requires perl to complete the final install step for users
2851 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
2852 and installs the conf, htdocs and htdocs/manual directories.
2855 *) Make mod_include use a hash table to associate directive tags with
2856 functions. This allows modules to implement their own SSI tags easily.
2857 The idea is simple enough, a module can insert it's own tag and function
2858 combination into a hash table provided by mod_include. While mod_include
2859 parses an SSI file, when it encounters a tag in the file, it does a
2860 hash lookup to find the function that implements that tag, and passes
2861 all of the relevant data to the function. That function is then
2862 responsible for processing the tag and handing the remaining data back
2863 to mod_include for further processing.
2864 [Paul J. Reder <rederpj@raleigh.ibm.com>]
2866 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
2867 fewer parameters: the local and remote socket addresses were removed
2868 from the parameter list because all required information is available
2869 via the APR socket. [Jeff Trawick]
2871 *) Distribution directory structure reorganized to reflect a
2872 normal source distribution with external install targets.
2875 *) The MPMs that need multiple segments of shared memory now create
2876 two apr_shmem_t variables, one for each shared memory allocation.
2877 the problem is that we can't determine how much memory will be required
2878 for shared memory allocations once we try to allocate more than one
2879 variable. The MM code automatically aligns the shared memory allocations,
2880 so we end up needing to pad the amount of shared memory we want based
2881 on how many variables will be allocated out of the shared memory segment.
2882 It is just easier to create a second apr_shmem_t variable, and two
2883 shmem memory blocks.
2886 *) Cleanup the export list a bit. This creates a single unified list of
2887 functions exported by APR. The export list is generated at configure
2888 time, and that list is then used to generate the exports.c file.
2889 Because of the way the export list is generated, we only export those
2890 functions that are valid on the platform we are building on.
2893 *) Enable logging the cookie with mod_log_config
2894 [Sander van Zoest <sander@covalent.net>]
2896 *) Fix a segfault in mod_info when it reaches the end of the configuration.
2899 *) Added lib/aputil/ as a placeholder for utility functions which are not
2900 specific to the Apache HTTP Server (but do not make sense with APR).
2901 The first utility is "apu_dbm": a set of functions to work with DBM
2902 files. This first version can be compiled for SDBM or GDBM databases.
2905 *) Complete re-write of mod_include. This makes mod_include a filter that
2906 uses buckets directly. This has now served the FAQ correctly.
2907 [Paul Reder <rederpj@raleigh.ibm.com>]
2909 *) Allow modules to specify the first filter in a sub_request when
2910 making the sub_request. This keeps modules from having to change the
2911 output_filter immediately after creating the sub-request, and therefore
2912 skip the sub_req_output_filter. [Ryan Bloom]
2914 *) Update ab to accept URLs with IPv6 literal address strings (in the
2915 format described in RFC 2732), and to build Host header fields in
2916 the same format. This allows IPv6 literal address strings to be
2917 used with ab. This support has been tested against Apache 1.3 with
2918 the KAME patch, but Apache 2.0 does not yet work with this format
2919 of the Host header field. [Jeff Trawick]
2921 *) Accomodate an out-of-space condition in the piped logs and the
2922 rotatelogs.c code, and no longer churn log processes for this
2923 condition. [Victor J. Orlikowski]
2925 *) Add support for partial writes with apr_sendfile() to core_output_filter.
2928 Changes with Apache 2.0a8
2930 *) Add a directive to mod_mime so that filters can be associated with
2934 *) Get multi-views working again. We were setting the path_info
2935 field incorrectly if we couldn't find the specified file.
2938 *) Fix 304 processing. The core should never try to send the headers
2939 down the filter stack. Always, just setup the table in the request
2940 record, and let the header filter convert it to data that is ready
2944 *) More fixes for the proxy. There are still bugs in the proxy code,
2945 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
2949 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
2952 *) APR: Add new apr_getopt_long function to handle long options.
2953 [B. W. Fitzpatrick <fitz@red-bean.com>]
2955 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
2956 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
2957 hostname resolution/address string parsing and building
2958 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
2959 of one of the apr_sockaddr_t structures for a socket. Change
2960 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
2962 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
2963 I have proxied pages with it, cleanup will commence soon.
2966 *) Make the proxy work with filters. This isn't perfect, because we
2967 aren't dealing with the headers properly. [Ryan Bloom]
2969 *) Do not send a content-length iff the C-L is 0 and this is a head
2970 request. [Ryan Bloom]
2972 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
2973 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
2975 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
2977 *) Get the default_handler to stop trying to deal with HEAD requests.
2978 The idea is to let the content-length filter compute the C-L before
2979 we try to send the data. If we can get the C-L correctly, then we
2980 should send it in the HEAD response.
2983 *) The Header filter can now determine if a body should be sent based
2984 on r->header_only. The general idea of this is that if we delay
2985 deciding to send the body, then we might be able to compute the
2986 content-length correctly, which will help caching proxies to cache
2987 our data better. Any handler that doesn't want to try to compute
2988 the content-length can just send an EOS bucket without data and
2989 everything will just work.
2992 *) Add the referer to the error log if one is available.
2993 [Markus Gyger <mgyger@itr.ch>]
2995 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
2996 change, the root of the configuration tree has been exposed to modules
2998 [Ryan Morgan <rmorgan@covalent.net>]
3000 *) Get the core_output_filter to use the bucket interface directly.
3001 This keeps us from calling the content-length filter multiple times
3002 for a simple static request.
3005 *) We are sending the content-type correctly now.
3006 [Ryan Bloom and Will Rowe]
3008 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
3009 a bogus bytes-sent value when the only thing being sent was trailers
3010 and writev() returned an error (or EAGAIN). [Jeff Trawick]
3012 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
3013 hints file to determine which platforms define
3014 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
3017 *) APR: add apr_get_home_directory() [Jeff Trawick]
3019 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
3021 *) Not all platforms have INADDR_NONE defined by default. Apache
3022 used to make this check and define INADDR_NONE if appropriate,
3023 but APR needs the check too, and I suspect other applications will
3024 as well. APR now defines APR_INADDR_NONE, which is always a valid
3025 value on all platforms.
3026 [Branko Èibej <brane@xbc.nu>]
3028 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
3029 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
3031 *) Relax the syntax checking of Host: headers in order to support
3032 iDNS. PR#6635 [Tony Finch]
3034 *) When reading from file buckets we convert to an MMAP if it makes
3035 sense. This also simplifies the default handler because the
3036 default handler no longer needs to try to create MMAPs.
3039 *) BUFF has been removed from the main server. The BUFF code will remain
3040 in the code until it has been purged from the proxy module as well.
3043 *) Byteranges have been completely re-written to be a filter. This
3044 has been tested, and I believe it is working correctly, but it could
3045 doesn't work for the Adobe Acrobat plug-in. The output almost matches
3046 the output from 1.3, the only difference being that 1.3 includes
3047 a content-length in the response, and this does not.
3050 *) APR read/write functions and bucket read functions now operate
3051 on unsigned integers, instead of signed ones. It doesn't make
3052 any sense to use signed ints, because we return the error codes,
3053 so if we have an error we should report 0 bytes read or written.
3056 *) Always compute the content length, whether it is sent or not.
3057 The reason for this, is that it allows us to correctly report
3058 the bytes_sent when logging the request. This also simplifies
3059 content-length filter a bit, and fixes the actual byte-reporing
3060 code in mod_log_config.c
3063 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
3064 it says, because it was only used by EOS and FLUSH buckets. Since
3065 neither of those are required at the end of a brigade, this was
3066 really signifying FLUSH_THE_DATA, but that can be determined better
3067 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
3068 buckets now return a length of 0, which is actually the amount of data
3069 read, so they make more sense.
3072 *) Allow the core_output_filter to save some data past the end of a
3073 request. If we get an EOS bucket, we only send the data if it
3074 makes sense to send it. This allows us to pipeline request
3075 responses. As a part of this, we also need to allocate mmap
3076 buckets out of the connection pool, not the request pool. This
3077 allows the mmap to outlive the request.
3080 *) Make blocking and non-blocking bucket reads work correctly for
3081 sockets and pipes. These are the only bucket types that should
3082 have non-blocking reads, because the other bucket types should
3083 ALWAYS be able to return something immediately.
3086 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
3087 server, but use Ctrl+Break to initiate a graceful restart
3088 instead of duplicating behavior. [John Sterling]
3090 *) Patch mod_autoindex to set the Last-Modified header based on
3091 the directory's mtime, and add the ETag header. [William Rowe]
3093 *) Merge the 1.3 patch to add support for logging query string in
3094 such a way that "%m %U%q %H" is the same as "%r".
3097 *) Port three log methods from mod_log_config 1.3 to 2.0:
3098 CLF compliant '-' byte count, method and protocol.
3101 *) Add a new LogFormat directive, %c, that will log connection
3102 status at the end of the response as follows:
3103 'X' - connection aborted before the response completed.
3104 '+' - connection may be kept-alive by the server.
3105 '-' - connection will be closed by the server.
3108 *) Expand APR for WinNT to fully accept and return utf-8 encoded
3109 Unicode file names and paths for Win32, and tag the Content-Type
3110 from mod_autoindex to reflect that charset if the the feature
3111 macro APR_HAS_UNICODE_FS is true. [William Rowe]
3113 *) Compute the content length (and add appropriate header field) for
3114 the response when no content length is available and we can't use
3115 chunked encoding. [Jeff Trawick]
3117 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
3118 so that content input filters get dechunked data when using
3119 the default handler. Also removed REQUEST_CHUNKED_PASS.
3122 *) Add mod_ext_filter as an experimental module. This module allows
3123 the administrator to use external programs as filters. Currently,
3124 only filtering of output is supported. [Jeff Trawick]
3126 *) Most Apache functions work on EBCDIC machines again, as protocol
3127 data is now translated (again). [Jeff Trawick]
3129 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
3130 the EBCDIC support. They are noops on ASCII machines, so this
3131 type of translation doesn't have to be surrounded by #ifdef
3132 CHARSET_EBCDIC. [Jeff Trawick]
3134 *) Fix mod_include. tag commands work again, and the server will
3135 send the FAQ again. This also allows mod_include to set aside
3136 buckets that include partial buckets.
3137 [Ryan Bloom and David Reid]
3139 *) Add suexec support back. [Manoj Kasichainula]
3141 *) Lingering close now uses the socket directly instead of using
3142 BUFF. This has been tested, but since all we can tell is that it
3143 doesn't fail, this needs to be really hacked on.
3146 *) Allow filters to modify headers and have those headers be sent to
3147 the client. The idea is that we have an http_header filter that
3148 actually sends the headers to the network. This removes the need
3149 for the BUFF to send headers.
3152 *) Charset translation: mod_charset_lite handles translation of
3153 request bodies. Get rid of the xlate version of ap_md5_digest()
3154 since we don't compute digests of filtered (e.g., translated)
3155 response bodies this way anymore. (Note that we don't do it at
3156 all at the present; somebody needs to write a filter to do so.)
3159 *) Input filters and ap_get_brigade() now have a input mode parameter
3160 (blocking, non-blocking, peek) instead of a length parameter.
3163 *) Update the mime.types file to the registered media types as
3164 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
3167 *) Namespace protect some macros declared in ap_config.h
3170 *) Support HTTP header line folding with input filtering.
3173 *) Mod_include works again. This should still be re-written, but at
3174 least now we can serve an SHTML page again.
3177 *) Begin to remove BUFF from the core. Currently, we keep a pointer
3178 to both the BUFF and the socket in the conn_rec. Functions that
3179 want to use the BUFF can, functions that want to use the socket,
3180 can. They point to the same place.
3183 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
3184 [Tomas "Ögren" <stric@ing.umu.se>]
3186 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
3187 associated pool goes away. (APR pipes on OS/2 were already had this
3188 logic.) This resolvs a fatal file descriptor leak with CGIs.
3191 *) The final line of the config file was not being read if there was
3192 no \n at the end of it. This was caused by apr_fgets returning
3193 APR_EOF even though we had read valid data. This is solved by
3194 making cfg_getline check the buff that was returned from apr_fgets.
3195 If apr_fgets return APR_EOF, but there was data in the buf, then we
3196 return the buf, otherwise we return NULL.
3199 *) Piped logs work again in the 2.0 series.
3202 *) Restore functionality broken by the mod_rewrite security fix:
3203 rewrite map lookup keys and default values are now expanded
3204 so that the lookup can depend on the requested URI etc.
3205 PR #6671 [Tony Finch]
3207 *) Tighten up the syntax checking of Host: headers to fix a
3208 security bug in some mass virtual hosting configurations
3209 that can allow a remote attacker to retrieve some files
3210 on the system that should be inaccessible. [Tony Finch]
3212 *) Add a pool bucket type. This bucket is used for data allocated out
3213 of a pool. If the pool is cleaned before the bucket is destroyed, then
3214 the data is converted to a heap bucket, allowing it to survive the
3218 *) Add a flush bucket. This allows modules to signal that the filters
3219 should all flush whatever data they currently have. There is no way
3220 to actually force them to do this, so if a filter ignores this bucket,
3221 that's life, but at least we can try with this.
3224 *) Add an output filter for sub-requests. This filter just strips the
3225 EOS bucket so that we don't confuse the main request's core output
3226 filter by sending multiple EOS buckets. This change also makes sub
3227 requests start to send EOS buckets when they are finished.
3230 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
3231 makes ap_bucket_destroy a return void, which is okay because it
3232 used to always return APR_SUCCESS, and nobody ever checked its
3233 return value anyway.
3234 [Cliff Woolley <cliffwoolley@yahoo.com>]
3236 *) Remove the index into the bucket-type table from the buckets
3237 structure. This has now been replaced with a pointer to the
3238 bucket_type. Also add some macros to test the bucket-type.
3241 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
3242 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
3243 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
3244 All _VAR_ flavors changes to _DATA to be absolutely clear.
3247 *) Add support for /, //, //servername and //server/sharename
3248 parsing of <Directory> blocks under Win32 and OS2.
3249 [Tim Costello, William Rowe, Brian Harvard]
3251 *) Remove the function pointers from the ap_bucket type. They have been
3252 replaced with a global table. Modules are allowed to register bucket
3253 types and use then use those buckets.
3256 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
3257 once we finish writing the request body to the cgi child process;
3258 otherwise, the client doesn't hit EOF on stdin. Small request bodies
3259 worked without this change (for reasons I don't understand), but large
3260 ones didn't. [Jeff Trawick]
3262 *) Remove file bucket specific information from the ap_bucket type.
3263 This has been moved to a file_bucket specific type that hangs off
3264 the data pointer in the ap_bucket type.
3267 *) Input filtering now has a third argument. This is the amount of data
3268 to read from lower filters. This argument can be -1, 0, or a positive
3269 number. -1 means give me all the data you have, I'll deal with it and
3270 let you know if I need more. 0 means give me one line and one line
3271 only. A positive number means I want no more than this much data.
3273 Currently, only 0 and a positive number are implemented. This allows
3274 us to remove the remaining field from the conn_rec structure, which
3278 *) Big cleanup of the input filtering. The goal is that http_filter
3279 understands two conditions, headers and body. It knows where it is
3280 based on c->remaining. If c->remaining is 0, then we are in headers,
3281 and http_filter returns a line at a time. If it is not 0, then we are
3282 in body, and http_filter returns raw data, but only up to c->remaining
3283 bytes. It can return less, but never more.
3284 [Greg Ames, Ryan Bloom, Jeff Trawick]
3286 *) mod_cgi: Write all of the request body to the child, not just what
3287 the kernel would accept on the first write. [Jeff Trawick]
3289 *) Back out the change that moved the brigade from the core_output_filters
3290 ctx to the conn_rec. Since all requests over a given connection
3291 go through the same core_output_filter, the ctx pointer has the
3295 *) Fix another bug in the send_the_file() read/write loop. A partial
3296 send by apr_send would cause unsent data in the read buffer to
3297 get clobbered. Complete making send_the_file handle partial
3298 writes to the network.
3301 *) Fix a couple of type fixes to allow compilation on AIX again
3302 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
3304 *) Fix bug in send_the_file() which causes offset to be ignored
3305 if there are no headers to send.
3308 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
3309 filter. Useful for supporting Windows 9* with a binary
3310 compiled on Windows NT.
3313 Changes with Apache 2.0a7
3315 *) Reimplement core_output_filter to buffer/save bucket brigades
3316 across multiple calls to the core_filter. The brigade will be
3317 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
3318 thresholds are hit or the EOS bucket is received.
3321 *) Create experimental filter (buffer_filter) that coalesces bytes
3322 into one large buffer before invoking the next filter in the
3323 chain. This filter is particularly useful with the current
3324 implementation of mod_autoindex when it inserted above the
3325 chunk_filter. mod_autoindex generates a lot of brigades that
3326 containing buckets holding just a few bytes each. The
3327 buffer_filter coalesces these buckets into a single large bucket.
3330 *) Add apr_sendfile() support into the core_output_filter.
3333 *) Add apr_sendv() support into the core_output_filter.
3336 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
3337 [Mike Abbott <mja@sgi.com>]
3339 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
3340 make much sense, because Apache uses buckets instead of BUFFs now.
3343 *) send_the_file now falls back to a read/write loop on platforms that
3344 do not have sendfile.
3345 [Ryan Bloom and Brian Havard]
3347 *) Install apachectl correctly, and substitute the proper values so
3348 that it works again. [Ryan Bloom]
3350 *) Better(??) handle platforms that lack sendfile().
3353 *) APR now has UUID generation/formatting/parsing support.
3356 *) Begin the http_filter. This is an input filter that understands
3357 the absolute basic amount required to parse an HTTP Request. The
3358 goal is to be able to split headers from request body before passing
3359 the data back to the other filters.
3362 *) Bring forward from 1.3.13 the config directory implementation
3365 *) install apxs if it is created
3368 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
3369 conversions. [William Rowe]
3371 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
3372 ap_add_output_filter(). [Jeff Trawick]
3374 *) Multiple build and configuration fixes
3377 -add datadir and localstatedir substitutions
3379 -fix logfilename misspelling
3380 -fix evaluation of installation dir variables and
3381 -replace $foobar by $(foobar) to be usefull in the makefile
3385 -add rules for cross-compiling in rules.mk. Okay, rule to check for
3386 $CC_FOR_BUILD is still missing
3387 -use CHECK_TOOL instead of CHECK_PROG for ranlib
3388 -add missing "AR=@AR@" to severaly Makefile.in's
3389 -cache result for "struct rlimit"
3390 -compile all helper programs with native and cross compiler
3391 and use the native version to generate header file
3392 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3394 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
3396 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
3398 *) Fix a bug where a client which only sends \n to delimit header
3399 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
3400 message. Start working on ebcdic co-existance with input
3402 [William Rowe, Greg Ames]
3404 *) If mod_so is enabled in the server always create libexec, even
3405 if there are no modules installed in this directory. This is a
3406 requirement for APXS to work correctly.
3409 *) Connection oriented output filters are now stored in the
3410 conn_rec instead of the request_rec. This allows us to add the
3411 output filter in the pre-connection phase instead of the
3412 post_read_request phase, which keeps us from trying to write an
3413 error page before we have a filter to write to the network.
3414 [Ryan Bloom, Jeff Trawick, and Greg Ames]
3416 *) Cleaning up an mmap bucket no longer deletes the mmap. An
3417 mmap can be used across multiple buckets (default_handler with
3418 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
3419 the mmap itself can't be associated with the bucket.
3422 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
3425 *) Radical surgery to improve mod_isapi support under Win32.
3426 Includes a number of newer ServerSupportFunction calls, support
3427 for ReadClient (in order to retrieve POSTs greater than 48KB),
3428 and general bug fixes to more reliably load ISAPI .dll's and
3429 prevent leaking handle resources. Note: There are still
3430 discrepancies between IIS's and Apache's ServerVariables, and
3431 async calls are still not supported. Additional warnings are
3432 logged to facilitate debugging of unsupported ISAPI calls.
3435 *) Add input filtering to Apache. The basic idea for the input
3436 filters is the same as the ideas for output filters. The biggest
3437 difference is that instead of calling ap_pass_brigade, ap_get_brigade
3438 should be called, and the order of execution for the filter itself is
3439 different. When writing an output filter, a brigade is passed in,
3440 and filters operate directly on that brigade, when done, they call
3441 ap_pass_brigade. Input filters are the exact opposite. Because input
3442 is not a push operation, filters first call ap_get_brigade. When this
3443 function returns, the input filter will be left with a valid brigade.
3444 The input filter should then operate on the brigade, and return.
3447 *) Fix building on BSD/OS using its native make. The build system
3448 falls back to the BSD .include directive on that host platform.
3451 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
3452 SHA1 and plaintext password encodings. Make feature tests a
3453 bit more flexible. [William Rowe]
3455 *) Charset translation: mod_charset_lite handles output content
3456 translation in a filter. mod_charset_lite no longer ignores
3457 subrequests. A bunch of cruft related to BUFF's support for
3458 translating request and response bodies was removed.
3461 *) Move the addition of the CORE filter to the post_read_request
3462 hook in http_core.c. This removes the need to add the filter in
3463 multiple places and allows for an SSL module to be added much
3464 simpler. [Ryan Bloom]
3466 *) Fix a security problem that affects certain configurations of
3467 mod_rewrite. If the result of a RewriteRule is a filename that
3468 contains expansion specifiers, especially regexp backreferences
3469 $0..$9 and %0..%9, then it may be possible for an attacker to
3470 access any file on the web server. [Tony Finch]
3472 *) Fix a bug where errors that are detected during early request parsing
3473 don't produce visible HTTP error messages at the browser, because
3474 the core_filter wasn't present. [Greg Ames]
3476 *) Provide apr_socklen_t as a portability aid.
3477 [Victor J. Orlikowski]
3479 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
3480 as well as a comment arg to the add, adduser and update cmds.
3481 update allows the user to clear or preserve pw/groups/comment.
3482 Fixed a bug in dbmmanage that prevented the check option from
3483 parsing a password followed by :group... text. Corrected the
3484 seed calcualation for Win32 systems, and added -lsdbm support.
3487 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
3490 *) Avoid a segfault when parsing .htaccess files. An
3491 uninitialized tree pointer was passed to ap_build_config().
3494 *) Change the way that inet_addr & inet_network are checked for
3495 in APR's configure process to allow BeOS BONE to correctly
3496 find them. With this change BeOS BONE now builds from source
3497 with no problems. [David Reid]
3499 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
3500 the end of the parameters to execve() was stored in the wrong
3501 location, overlaying the storage beyond the newargs[] array and
3502 also passing uninitialized storage to execve(), which would
3503 sometimes fail with EFAULT. [Jeff Trawick]
3505 *) Fix a bug parsing configuration file containers. With a sequence
3506 like this in the config file
3508 <IfModule mod_kilroy.c>
3511 <IfModule mod_lovejoy.c>
3516 the second container would be terminated at the blank line due to
3517 sediment in the buffer from reading the prior </IfModule> and an
3518 error message would be generated for the real </IfModule> for the
3519 second container. Also due to this problem, any two characters
3520 could be used for "</" in the close of a container.
3523 *) ap_add_filter prototype changed to remove the ctx pointer. The
3524 pointer still remains in the filter structure, but it can not be
3525 a part of the ap_add_filter prototype. The reason is that when
3526 the core uses AddFilter to add a filter to the stack it doesn't
3527 know how to allocate the ctx pointer, or even how much memory should
3528 be allocated. The filters will have to be responsible for allocating
3529 the ctx memory when they need it.
3532 *) Add an AddFilter directive. This directive takes a list of filters
3533 that should be activated for the requested resource.
3536 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
3537 some other platforms). [Jeff Trawick]
3539 *) Modify mod_include to be a filter. Currently, it has only been tested
3540 on actual files, but it should work for CGI scripts too.
3543 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
3544 writes. apr_flush() for Unix: handle interrupted writes.
3547 *) NameVirtualHost can now take "*" as an argument instead of
3548 an IP address. This allows you to create a purely name-based
3549 virtual hosting server that does not have any IP addresses in
3550 the configuration file and which ignores the local address
3551 of any connections. PR #5595, PR #4455 [Tony Finch]
3553 *) Fix some compile warnings in mod_mmap_static.c
3554 [Mike Abbott <mja@sgi.com>]
3556 *) Fix chunking problem with CGI scripts. The general problem was that
3557 the CGI modules were adding an EOS bucket and then the core added an
3558 EOS bucket. The chunking filter finalizes the chunked response when it
3559 encounters an EOS bucket. Because two EOS buckets were sent, we
3560 finalized the response twice. The fix is to make sure we only send one
3561 EOS, by utilizing a flag in the request_rec.
3564 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
3565 and Win32. Previously, the first read from an apr_file_t set up via
3566 apr_put_os_file() would return a '\0'. [Jeff Trawick]
3568 *) Mod_cgid now creates a single element bucket brigade, with a pipe
3569 bucket, instead of using BUFF's and ap_r*.
3572 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
3573 [Mike Abbott <mja@sgi.com>]
3575 *) Remove ap_bopenf from buff code. This required modifying the file_cache
3576 code to use APR file's directly instead of going through BUFFs.
3579 *) Fix compile break on some platforms for mod_mime_magic.c
3580 [John K. Sterling <sterling@covalent.net>]
3582 *) Fix merging of AddDefaultCharset directive.
3583 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
3585 *) Minor revamp of the rlimit sections of code. We now test
3586 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
3587 is now "available" even if the platform doesn't support
3588 the rlimit family (it's just a noop though). [Jim Jagielski]
3590 *) Migrate the pre-selection of which MPM to use for specific
3591 platforms to hints.m4, which contains (or should contain)
3592 all platform specific "hints". [Jim Jagielski]
3594 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
3597 *) Add tables with non-string/binary values to APR.
3600 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
3603 *) Update PCRE to version 3.2. [Ryan Bloom]
3605 *) Change the way buckets' destroy functions are called so that
3606 they can be more directly used when changing the type of a
3607 bucket in place. [Tony Finch]
3609 *) Add generic support for reference-counting the resources used by
3610 buckets, and alter the HEAP and MMAP buckets to use it. Change
3611 the way buckets are initialised to support changing the type of
3612 buckets in place, and use it when setting aside TRANSIENT buckets.
3613 Change the implementation of TRANSIENT buckets so that it can be
3614 mostly shared with IMMORTAL buckets, which are now implemented.
3617 Changes with Apache 2.0a6
3619 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
3621 *) Add a chunking filter to Apache. This brings us one step closer
3622 to removing BUFF. [Ryan Bloom]
3624 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
3625 added to the stack is the last filter to be called. [Ryan Bloom]
3627 *) Apache 2.0 has been completely documented using Scandoc. The
3628 docs can be generated by running 'make docs'. [Ryan Bloom]
3630 *) Add filtered I/O to Apache. This is based on bucket brigades,
3631 Currently the buckets still use BUFF under the covers, but that
3632 should change quickly. The only currently written filter is the
3633 core filter which just calls ap_bwrite. [The Apache Group]
3635 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
3636 built with thread support. [Jeff Trawick]
3638 *) Abort configuration if --with-layout was specified and there's
3639 no layout definition file. [Ken Coar]
3641 *) Add support for '--with-port=n' option to configure. [Ken Coar]
3643 *) Add support for extension methods for the Allow response header
3644 field, and an API routine for accessing r->allowed and the
3645 list of extension methods in a unified manner. [Ken Coar]
3647 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
3648 [Rob Simonson <simo@us.ibm.com>]
3650 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
3651 APACHE_XLATE builds. [Jeff Trawick]
3653 *) A configuration file parsing problem was fixed. When the
3654 configuration file started with an IfModule/IfDefine container,
3655 only the last statement in the container would be retained.
3658 Changes with Apache 2.0a5
3660 *) Perchild is serving pages after passing them to different child
3661 processes. There are still a lot of bugs, but this does work. I
3662 have made requests against the same installation of Apache, and had
3663 different servers use different user IDs to serve the responses.
3664 This change moves to using socketpair instead of an AF_UNIX socket.
3667 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
3668 It can't seem to pass between child processes yet, but I think we
3669 are closer now than before. This moves us back to using Unix
3670 Domain Sockets. [Ryan Bloom]
3672 *) libapr functions and types renamed with apr_ prefix.
3673 #include "apr_compat.h" for 1.3.x backwards compat
3676 *) Fix problems with APR sockaddr handling on Win32. It didn't always
3677 return the right information on the local socket address.
3678 [Gregory Nicholls <gnicholls@level8.com>]
3680 *) ap_recv() on Win32: Set bytes-read to 0 on error.
3681 [Gregory Nicholls <gnicholls@level8.com>]
3683 *) Add an option to not detach from the controlling terminal without
3684 going into single process mode. This allows for much easier
3685 debugging of the process startup code. [Ryan Bloom]
3687 *) ab: don't use perror() to report the failure of an APR function.
3690 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
3691 scoreboard on graceful restarts.
3694 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
3695 An invalid ap_proc_t was passed to ap_create_process().
3698 *) Allow modules to register filters. Those filters are still
3699 never called, but this is a step in the right direction.
3700 [Ryan Bloom and Greg Stein]
3702 *) Register the mod_cgid daemon process for cleanup so that it is
3703 killed at termination if it does not die when the parent gets
3704 SIGTERM. This change is to fix occasional problems where the
3705 process stays around. Bugs in similar logic in mod_rewrite and
3706 mod_include were also fixed. [Jeff Trawick]
3708 *) Fix a bug in the time handling. Basically, we were imploding a time
3709 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
3710 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
3711 uses those two fields to adjust the time value. Because of the HTTP
3712 spec, both of those values can be zero'ed out safely. This fixes
3713 the bug correctly. [Ryan Bloom]
3715 *) Fix a couple of place in the Windows code where the wrong error
3716 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
3718 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
3720 *) Added the APR_EOL_STR macro for platform dependent differences in
3721 logfiles and other raw text (such as all APR files). Fixes logfiles
3722 not terminated with cr/lf sequences in Win32. [William Rowe]
3724 *) Move all strings functions in APR to src/lib/apr/strings and create
3725 apr_strings.h for the prototypes. [Ryan Bloom]
3727 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
3728 to repeat the syscall until we stop getting EINTR. I noticed a
3729 related problem at termination (SIGTERM) on FreeBSD when using
3730 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
3731 implementation work properly with child init. Previously, ap_lock()
3732 was essentially a no-op because all children were using different
3733 locks and thus nobody ever blocked. [Jeff Trawick]
3735 *) The htdocs/ tree has been moved out of the CVS source tree into
3736 a separate area for easier development. This has NO EFFECT on
3737 end-users or Apache installations. [Ken Coar]
3739 *) Integrate the mod_dav module for WebDAV protocol handling. This
3740 adds the dav and dav_fs modules, the SDBM library, and additional
3741 XML handling utilities. [Greg Stein]
3743 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
3746 *) Update the lib/expat-lite/ library (bring forward changes from
3747 the Apache 1.3 repository). [Greg Stein]
3749 *) If sizeof(long long) == sizeof(long), then prefer long in APR
3750 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
3752 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
3753 machines where sendfile is detected, but nobody has written ap_sendfile.
3754 [Dave Hill <ddhill@zk3.dec.com>]
3756 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
3758 *) ab would start up more connections than needed, then quit when the
3759 desired number were finished. Also fixed a logic error involving
3760 ab keepalives. [Victor J. Orlikowski]
3762 *) WinNT: Implement non-blocking pipes with timeouts to communicate
3763 with CGIs. Apache 2.0a4 had non-blocking pipes but without
3764 timeouts (i.e, if a timeout was specified, the pipe reverted to
3765 a full blocking pipe). Now the behaviour is more in line with
3766 Unix non-blocking pipes.
3769 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
3770 cache open file handles along with accept socket reuse enables
3771 Apache 2.0 to serve non-keepalive requests for static files at
3772 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
3773 and Apache 2.0 will serve almost 1200 rps on my system).
3776 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
3777 supports two config directives, mmapfile (same behavious as
3778 mod_mmap_static) and cachefile. Use the cachefile directive
3779 to cache open file handles. This directive only works on systems
3780 that have implemented the ap_sendfile API. cachefile works today
3781 on Windows NT, but has not been tested on any flavors of Unix.
3784 *) Cleanup the configuration. With the last few changes the
3785 configuration process automatically:
3786 inherits information about how to build from APR. Allowing
3787 APR to inform Apache that it should or should not use -ldl
3789 Detects which mod_cgi should be used mod_cgi or mod_cgid,
3790 based on the threading model
3792 Apache calls APR's configure process before finishing it's
3793 configuration processing, allowing for more information flow
3798 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
3799 with non-zero argument makes the socket non-blocking. BeOS and
3800 OS/2 already worked this way. [Jeff Trawick]
3802 *) ap_close() now calls ap_flush() for buffered files, so write
3803 operations work a whole lot better on buffered files.
3806 *) Fix error messages issued from MPMs which explain where to change
3807 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
3810 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
3811 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
3812 now the way that the blocking state of a pipe is manipulated.
3813 ap_block_pipe() is gone. [Jeff Trawick]
3815 *) Correct the problem where the only local host name that the IP stack
3816 can discover are 'undotted' private names. If no fully qualified
3817 domain name can be identified, the default ServerName will be set to
3818 the machine's IP address string. A warning is always provided if the
3819 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
3821 *) Repair problems with config file processing which caused segfault
3822 at init when virtual hosts were defined and which caused ServerName to
3823 be ignored when there was no valid DNS setup. [Jeff Trawick]
3825 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
3827 *) Add ap_sendfile implementation for AIX
3828 [Victor J. Orlikowski]
3830 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
3831 apr_network_io.h, and apr_thread_proc.h.
3832 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
3834 *) Bring the allocation and pool debugging code back into a working
3835 state. This will need to be tested as so far it's only been used on
3838 *) Change configuration command setup to be properly typesafe when in
3839 maintainer mode. Note that this requires a compiler that can initialise
3840 unions. [Ben Laurie]
3842 *) Turn on buffering for config file reads. Part of this was to
3843 repair buffered I/O support in Unix and implement buffered
3844 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
3846 *) Win32: Fix problem where UTC offset was not being set correctly
3847 in the access log. Problem reported on news group by Jerry Baker.
3850 *) Fix segfault when reporting this type of syntax error:
3851 "</container> without matching <container> section", where
3852 container is VirtualHost or Directory or whatever.
3855 *) Prevent the source code for CGIs from being revealed when using
3856 mod_vhost_alias and the CGI directory is under the document root
3857 and a user makes a request like http://www.example.com//cgi-bin/cgi
3858 as reported in <news:960999105.344321@ernani.logica.co.uk>
3861 *) Add support for the new Beos NetwOrking Environment (BONE)
3864 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
3865 final input char is incomplete; ap_bwrite_xlate() now handles
3866 incomplete final input chars. [Jeff Trawick]
3868 *) Yet another update to saferead/halfduplex stuff -- need to ensure
3869 that a bhalfduplex call occurs before logging or else DNS and
3870 such can delay the last packet of the response. [Dean Gaudet]
3872 *) Some syscall reduction in APR on unix -- don't seek when setting
3873 up an mmap; and don't fcntl() more than once per socket.
3876 *) When mod_cgid is started as root, the cgi daemon now switches
3877 to the configured User/Group (like other httpd processes)
3878 instead of continuing as root. [Jeff Trawick]
3880 *) The prefork MPM now uses an APR lock for the accept() mutex.
3881 It has not been getting a lock at all recently. httpd -V now
3882 displays APR's selection of the lock mechanism instead of the
3883 symbols previously respected by prefork. [Jeff Trawick]
3885 *) Change the mmap() feature test to check only for existence.
3886 The previous check required features not used by Apache.
3889 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
3890 sometimes mangled. The len parm to accept() was not
3891 initialized, leading sometimes to an endless loop of failed
3892 accept() calls on OS/390 and anywhere else that failed the call
3893 if the len was negative. Use <sys/un.h> for struct sockaddr_un
3894 instead of declaring it ourselves to fix a compilation problem
3895 on Solaris. [Jeff Trawick]
3897 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
3899 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
3901 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
3903 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
3904 initialization if ALLOC_DEBUG is defined; no known symptom
3905 otherwise. [Jeff Trawick]
3907 *) Fix typo in configure script when checking for mod_so. bash
3908 doesn't seem to have a problem but /bin/sh on Solaris does.
3909 Symptom: "./configure: test: unknown operator =="
3912 *) Rebind the Win32 NT and 9x services control into the MPM.
3913 All console, WinNT SCM and Win9x pseudo-service control code is
3914 now wrapped within the WinNT MPM.
3917 *) Make a copy of getenv("PATH") before storing for later use. Some
3918 getenv() implementations use the same storage for successive calls.
3919 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
3921 *) Server Tokens work in 2.0 again. This also propogates the change
3922 to allow just the product name in the server string using
3926 Changes with Apache 2.0a4
3928 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
3929 won't need to call it. [Greg Ames, Jeff Trawick]
3931 *) Move pre_config hook call to between configuration read and config
3932 tree walk. This allows all modules to implement pre_config hooks
3933 and know that they will be called at an appropriate time.
3936 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
3939 *) Add pre-config hooks back to all modules.
3942 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
3943 ContentDigest enabled and we can't/don't mmap the file.
3946 *) We now report the correct line number for syntax errors in config
3947 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
3949 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
3950 related bugs, and changed shmem/locking to use apr API. Shared-mem
3951 is currently disabled, however, because of problems with graceful
3952 restarts. [Ronald Tschalär]
3954 *) Fix corruption of IFS variable in --with-module= handling.
3955 Depending on the user's shell or customization thereof, there
3956 would be errors generating ap_config_auto.h later in the configure
3957 procedure. [Jeff Trawick]
3959 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
3960 isn't used (as in 1.3), except that on Unix it is now logged via
3961 ap_log_rerror() instead of by the child having STDERR_FILENO refer
3962 to the error log. [Greg Ames, Jeff Trawick]
3964 *) Add '-D' argument processing for run time configuration defines.
3967 *) Organize http_main.c as independent code, such that no code or
3968 global data is exported from it. WIN32 will dynamically link it
3969 to the server core, so this will prevent mutual dependency.
3972 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
3973 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
3976 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
3977 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
3979 *) Add mod_charset_lite for configuring character set translation.
3982 *) Add '-n' option to htpasswd to make it print its user:pw record
3983 on stdout rather than having to frob a text file. [Ken Coar]
3985 *) Fix saferead. Basically, we flush the output buffer if a read on the
3989 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
3990 a conversion is single-byte only. [Jeff Trawick]
3992 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
3993 the BeOS 5.0 documentation says that shutdown doesn't work yet.
3996 *) Fix some minor errors where pid was being manipulated as an int
3997 instead of the portable pid_t. [Roy Fielding]
3999 *) Fix some error log prints that were printing the pointer to a
4000 structure rather than the pid within the structure.
4001 [Jeff Trawick, Roy Fielding]
4003 *) ab: Fix a command-line processing bug; track bad headers in
4004 err_response; support reading headers up to 2K.
4005 [Ask Bjoern Hansen <ask@valueclick.com>]
4007 *) Fix ap_resolve_env() so that it handles new function added in a prior
4008 alpha (see "Added the capability to do ${ENVVAR} constructs in the
4009 config file.") as well as the constructs used by mod_rewrite.
4010 [Paul Reder <rederpj@raleigh.ibm.com>]
4012 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
4014 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
4015 APR to perform translation, instead of accessing the hard-coded tables
4016 in 1.3's ebcdic.c. [Jeff Trawick]
4018 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
4021 *) Add the ability to hook into the config file reading phase. Basically
4022 if a directive is specified EXEC_ON_READ, then when that directive is
4023 read from the config file, the assocaited function is executed. This
4024 should only be used for those directives that must muck with HOW the
4025 server INTERPRETS the config. This should not be used for directives
4026 that re-order or replace items in the config tree. Those changes should
4027 be made in the pre-config step.
4030 *) Add mod_example to the build system.
4033 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
4034 byte character sets. [Jeff Trawick]
4036 *) Pick up various EBCDIC fixes from 1.3 (from Martin
4037 Kraemer and Oliver Reh originally according to the change log).
4040 *) Fix a couple of problems in RFC1413 support (controlled by the
4041 IdentityCheck directive). Apache did not build the request string
4042 properly and more importantly Apache would loop forever if the
4043 would-be ident server dropped the connection before sending a
4044 properly terminated response. [Jeff Trawick]
4046 *) apxs works in 2.0.
4049 *) Reliable piped logs work in 2.0.
4052 *) Introduce a hash table implementation into APR to be used for
4053 replacing tables and other random data structures in Apache.
4056 *) Add some more error reporting to htpasswd in the case of problems
4057 generating or accessing the temporary file. Also, pass in a
4058 buffer if the implementation knows how to use it (i.e., if L_tmpnam
4059 is defined). [Ken Coar]
4061 *) Configure creates config.nice now containing your configure
4062 options. Syntax: ./config.nice [--more-options]
4065 *) Fix various return code problems in APR on Win32. For most of
4066 these, APR was returning APR_EEXIST instead of GetLastError()/
4067 WSAGetLastError(). [Jeff Trawick]
4069 *) Make piped logs work again in version 2.0
4072 *) Add VPATH support to UNIX build system of Apache and APR.
4075 *) Fix ap_tokenize_to_argv to respect the const arguments that are
4079 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
4080 Patch submitted to author.
4083 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
4084 /sbin in PATH on FreeBSD (all submitted to rse previously)
4087 *) Fix building Pthread-based MPMs on OpenBSD
4088 [Sascha Schumann] PR#26
4090 *) Fix ap_readdir() problem on systems where d_name[] field in
4091 struct dirent is declared with only one byte. (This problem only
4092 affected multithreaded builds.) This caused a segfault during
4093 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
4094 least). [Jeff Trawick]
4096 *) Fix some make-portability problems on at least Tru64, Irix
4098 [Sascha Schumann] PR#18, PR#39
4100 *) Add ap_sigwait() to support old-style sigwait() on systems
4101 like OS/390 and UnixWare.
4104 *) Add POSIX-thread flags for more platforms.
4107 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
4108 (on Unix, at least) to handle resolver errors. Fix a bug in
4109 the definition of APR_ENOMEM so that ap_strerror() can spit
4110 out the correct error message for it.
4113 Changes with Apache 2.0a3
4115 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
4118 *) API: *HOOK* macros now have an AP_ prefix
4121 *) Win32: Eliminate redundant calls to initialize winsock.
4122 [Tim Costello <timcostello@ozemail.com.au>]
4124 *) Fix bugs initializing ungetchar for pipes.
4125 [Chia-liang Kao <clkao@CirX.ORG>]
4127 *) The ab program in the src/support directory is now portable using
4131 *) Support directory is being compiled when the server is built
4134 *) The configure option --with-program-name has been added to allow
4135 developers to rename the executable at configure time. This also
4136 changes the name of the config files to match the executable's name.
4139 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
4140 containing version numbers. [Martin Pool]
4142 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
4143 Unix; access_log and error_log now created with these perms; non-
4144 Unix is unaffected [Jeff Trawick]
4146 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
4147 Replaced more magic numbers with MD5_DIGESTSIZE.
4148 [William Rowe, Roy Fielding]
4150 *) Win32: Get mod_auth_digest compiling and added to the Windows
4151 build environment. Not tested and I'd be suprised if it
4152 actually works. [Bill Stoddard]
4154 *) Revamp the Win32 make environment. Makefiles have been removed and
4155 Apache.dsw created to bring together all the pieces. Create new file
4156 os/win32/BaseAddr.ref to define module base addresses (to prevent
4157 dll relocation at start-up).
4158 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
4160 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
4161 of the \015, \012, and \015\012 constants with macros.
4164 *) Add ap_xlate_open() et al for translation of text between different
4165 character sets. The initial implementation requires iconv().
4168 *) More FAQs and answers from comp.infosystems.www.servers.unix.
4169 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4171 *) CGI output is being timed out now.
4174 *) Fix the problem with dieing quietly. dupfile now takes a pool which
4175 is used by the new apr file. There is no reason to create a new file
4176 with the same lifetime as the original file.
4179 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
4180 module base addresses. This will help shooting seg faults
4181 in the field. [William Rowe <wrowe@lnd.com>]
4183 *) Update Apache on Windows documentation. Add new document
4184 describing how to compile Apache on Windows.
4185 [William Rowe <wrowe@lnd.com>]
4187 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
4188 microseconds instead of seconds. Some storage leaks and other
4189 minor bugs in related code were fixed. [Jeff Trawick]
4191 *) Win32: First cut at getting mod_isapi working under 2.0
4192 [William Rowe <wrowe@lnd.com>]
4194 *) First stab at getting mod_auth_digest working under 2.0
4195 quick change summary:
4196 - moved the random byte generation (ap_generate_random_bytes) into APR
4197 - now uses ap_time_t
4198 - compiles and runs on linux
4200 [Brian Martin <bmartin@penguincomputing.com>]
4202 *) Win32: Move the space stripping of physical service names
4203 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
4204 unresolved symbol. Add dependency checking to the
4205 CreateService call to ensure TCPIP and AFP (winsock) is started
4207 [William Rowe <wrowe@lnd.com>]
4209 *) Win32: Add code to perform latebinding on functions that may
4210 not exist on all levels of Windows where Apache runs. This
4211 is needed to allow Apache to start-up on Win95/98. All calls
4212 to non portable functions should be protected with
4213 ap_oslevel checks to prevent runtime segfaults.
4214 [William Rowe <wrowe@lnd.com>]
4216 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
4218 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
4220 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
4221 This addresses PR 1623. Still need to address timing out runaway
4222 CGI scripts. [Bill Stoddard]
4224 *) Win32: Make ap_stat Windows 95/98 friendly
4225 [William Rowe <wrowe@lnd.com>]
4227 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
4228 always fail. Need to initialise the dwOSVersionInfoSize member of the
4229 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
4232 The patch also enhances ap_get_oslevel (and the associated enum) to
4233 handle selected service packs for NT4, and adds recognition for
4234 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
4235 we can use ReadFileScatter and WriteFileGather in readwrite.c.
4236 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
4238 *) Get mod_rewrite building and running, and mod_status building for Win NT
4239 [Allan Edwards <ake@raleigh.ibm.com>]
4241 *) Patch to port mod_auth_db to the 2.0 api and also to support
4242 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
4243 2.7.7. It should work with version 1 as well but I haven't tested it.
4244 [Brian Martin <bmartin@penguincomputing.com>]
4246 *) Get APR DSO code working under Windows. Includes cross platform
4248 [Tim.Costello@BTFinancialgroup.com]
4250 *) Fix some of the Windows APR time functions.
4253 *) FAQ changes related to tidying up historical documents on the web site.
4254 [Joshua Slive <slive@finance.commerce.ubc.ca>]
4256 *) Move Windows DSO code into APR.
4259 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
4260 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
4261 at build time. At this point, the server will not compile on Windows because
4262 of the recent DSO commits. Fixing those next.
4263 [Bill Rowe & Bill Stoddard]
4265 *) Added error checking for file I/O APR routines.
4266 [Jon Travis <jtravis@covalent.net>]
4268 *) APR: Don't use the values of resolver error codes for the
4269 corresponding APR error codes. On Unix and Win32, return the
4270 proper APR error code after a resolver error. [Jeff Trawick]
4272 Changes with Apache 2.0a2
4274 *) Renamed the executable back to httpd on all platforms other
4278 *) Allow BeOS to survive restarts, log properly and a few
4279 small things it had problems with due to the way it setup
4280 users and groups. [David Reid]
4282 *) Get mod_rewrite working with APR locks
4283 [Paul Reder <rederpj@raleigh.ibm.com>]
4285 *) Actually remove the sempahore when the lock cleanup routine
4286 is called on BeOS. [David Reid]
4288 *) Clear hook registrations between reads of the config file.
4289 When DSOs are unloaded and re-loaded the old hook pointers may
4290 no longer be valid. This fix eliminates potential segfaults.
4291 [Allan Edwards <ake@raleigh.ibm.com>]
4293 *) Fix a problem with Sigfunc not being defined or bypassed
4294 if sigaction() wasn't found. [Jim Jagielski]
4296 *) Fix the locking mechanism on BSD variants. They now use fcntl
4297 locks. This allows the server to start and serve pages.
4300 *) First cut at getting the Win32 installer to work
4301 [William Rowe <wrowe@lnd.com>]
4303 *) Get htpasswd compiling under Windows
4304 [William Rowe <wrowe@lnd.com>]
4306 *) Change the log message for a bind() failure to show the
4307 interface and port number. [Jeff Trawick]
4309 *) Import the documentation from 1.3.12 and bring parts of it
4310 up-to-date with respect to the changes that have occurred
4314 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
4315 now logged correctly on BeOS.
4318 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
4319 Makefile.win includes the same user interface as the old
4321 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
4323 *) Win32 exec now uses COMSPEC environment string for command
4324 shell path resolution.
4325 [William Rowe <wrowe@lnd.com>] PR#3715
4327 *) Win32: ap_connect() was not returning correct error condition
4329 [Allen Prescott <allen@clanprescott.com>]
4331 *) Win32: ap_open() was broken on Win9x because an NT-specific
4332 flag was passed to CreateFile. ap_puts() added an unnecessary
4334 [Jeff Trawick <trawick@us.ibm.com>]
4336 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
4337 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
4338 confusing ee/et name and made all extensions language/dialect
4339 rather than country reflecting. Changed example files to
4340 explicit reflect the ISO charset and added a few common
4341 ones to the example config [dirkx]
4343 *) Extend external module capability. To use this, you call
4344 configure with --with-module=path/to/mod1,path/to/mod2,etc.
4347 *) Backported the various "default charset" fixes from 1.3.12,
4348 including the AddDefaultCharset directive. [Jim Jagielski]
4350 *) Added the capability to do ${ENVVAR} constructs in the
4351 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
4352 it does this on a line by line basis; i.e. if the envvar
4353 expands to something with spaces you have to protect it
4354 by adding quotes around it (Unless of course you expect it
4355 to contains more than one argument. Alternatively you
4356 can compile it on a per token basis; which is what people
4357 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
4358 hampers fancier hacks.
4359 [Dirk-Willem van Gulik]
4361 *) Changed the 'ErrorDocument' syntax in that it NO longer
4362 supports the asymetric
4364 ErrorDocument 301 "Some message
4366 Note the opening " quote, without a closing quote. It now
4367 has either the following syntaxes
4369 ErrorDocument XXX /local/uri
4370 ErrorDocument XXX http://valid/url
4371 ErrorDocument XXX "Some Message"
4373 The recognition heuristic is: if it has a space it
4374 is a message. If it has no spaces and starts with a /
4375 or is a valid URL then treat it that way. Otherwise it
4376 is assumed to be a message.
4378 This breaks backward compatibility but makes live a hell
4379 of a lot easier for GUI's and config file parsers.
4380 [Dirk-Willem van Gulik]
4382 *) Changed 'CacheNegotiatedDocs' from its present/not-present
4383 syntax into a 'on' or 'off' syntax. As it currently is the
4384 only non nesting token which uses NO_ARGS and thus is an
4385 absolute pain for any config interface automation. This
4386 breaks backward compatibility. [Dirk-Willem van Gulik]
4388 *) Add ability to add external modules to the build process. This is
4389 done with --with-module=/path/to/module. Modules can only be added
4390 as static modules at this point.
4393 Changes with Apache 2.0a1
4395 *) Fix FreeBSD 3.3 core dump.
4396 Basically, ap_initialize() needs to get called before
4397 create_process(), since create_process() passes op_on structure
4398 to semop() to get a lock, but op_on isn't initialized until
4399 ap_initialize() calls setup_lock(). Here is a slight
4400 rearrangement to main() which calls ap_initialize() earlier...
4401 [Jeff Trawick <trawick@us.ibm.com>]
4403 *) Enable Apache to use sendfile/TransmitFile API
4404 [Bill Stoddard, David Reid, Paul Reder]
4406 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
4410 *) Make file I/O and network I/O writev/sendv APIs consistent.
4411 Eliminate use of ap_iovec_t and use Posix struct iovec.
4412 Use seperate variable on ap_writev to set the number of iovecs
4413 passed in and number of bytes written.
4416 *) Adapt file iol to use APR functions. Replaced ap_open_file()
4417 with ap_create_file_iol(). ap_create_file_iol() requires that
4418 the file be opened prior to the call using ap_open().
4421 *) Port mod_include and mod_cgi to 2.0
4422 [Paul Reder, Bill Stoddard]
4424 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
4425 bytes_read/bytes_written is always valid (never -1). Plus
4426 some fixes to buff.c to correct problems introduced by the
4427 errno => ap_status_t changes a while back. Plus a fix to
4428 chunked encoding introduced right at the beginning of 2.0.
4431 *) Revamped UNIX build system to use autoconf and libtool.
4432 [Manoj Kasichainula, Sascha Schumann]
4434 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
4436 *) More rigorous checking of Host: headers to fix security problems
4437 with mass name-based virtual hosting (whether using mod_rewrite
4438 or mod_vhost_alias).
4439 [Ben Hyde, Tony Finch]
4441 *) Add back support for UseCanonicalName in <Directory> containers.
4442 [Manoj Kasichainula]
4444 *) Added APLOG_STARTUP log type. This allows us to write an error
4445 message without any of the date and time information. As a part
4446 of this change, I also removed all of the calls to fprintf(stderr
4447 and replaced them with calls to ap_log_error using APLOG_STARTUP
4448 writing to stderr is no longer portable, because we don't direct
4449 stderr to the error log on all platforms.
4452 *) Convert error logging functions to take errno as an argument.
4453 This makes our error logs more portable, because some Windows API's
4454 don't set errno. This change allows us to still output a valid
4455 message on all of our platforms.
4458 *) mod_mime_magic runs in 2.0-dev now.
4459 [Paul Reder <rederpj@raleigh.ibm.com>]
4461 *) sendfile has been added to APR.
4462 [John Zedlewski <zedlwski@Princeton.EDU>]
4464 *) buff.c has been converted to no longer use errno.
4465 [Manoj Kasichainula]
4467 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
4468 interface adaption to APR functions did it. [Martin Kraemer]
4470 *) Support DSOs properly on 32-bit HP-UX 11.0
4471 [Dilip Khandekar <dilip@cup.hp.com>]
4473 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
4474 [Ralf S. Engelschall]
4476 *) Cleaned APR build environment integration and bootstrap APR
4477 automatically for developers from src/Configure.
4478 [Ralf S. Engelschall]
4480 *) Fixed building of src/support/htpasswd.c
4481 [Ralf S. Engelschall]
4483 *) When generating the Location: header, mod_speling forgot
4484 to escape the spelling-fixed uri. (Forw-Port from 1.3)
4487 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
4489 *) Change all pools to APR contexts. This is the first step to
4490 incorporating APR into Apache. [Ryan Bloom]
4492 *) Move "handler not found" warning message to below the check
4493 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
4494 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
4496 *) Support line-continuation feature in config.option file and
4497 allow the loading of multiple option sections at once via
4498 ``--with-option=<section1>,<section2>,...''
4499 [Ralf S. Engelschall]
4501 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
4503 Changes with Apache MPM
4505 *) Use asynchronous AcceptEx() and a completion port to accept and
4506 dispatch connections to threads in Windows NT/2000.
4509 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
4512 *) Implement the APACI --with-option facility
4513 (per default used the config.option file).
4514 [Ralf S. Engelschall]
4516 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
4518 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
4519 Replace pre_connection module call with a register_hook call and
4520 implement pre_connection as a hook. The intent is that these hooks will
4521 be extended to allow Apache to be multi-protocol, and also to allow the
4522 calling order to be specified on a per-hook/per-module basis.
4525 *) Implement mpm_* methods as "modules". Each method gets its own
4526 subdir in src/modules (eg: src/modules/prefork). Selection
4527 of method uses Rule MPM_METHOD. [Jim Jagielski]
4529 *) Port the hybrid server from the apache-apr repository as
4530 mpm_mpmt_pthread. [Manoj Kasichainula]
4532 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
4533 amongst the unix MPMs.
4535 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
4536 signal handling for the new world order. [Dean Gaudet]
4538 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
4539 of alloc.c for now. [Dean Gaudet]
4541 *) Handle partial large writes correctly. [Ben Laurie]
4543 *) Eliminate conn_rec's pointer to server. All it knows is the base server
4544 based on IP/port. [Ben Laurie]
4546 *) Port a bunch of modules to the new module structure.
4547 ["Michael H. Voase" <mvoase@midcoast.com.au>]
4549 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
4551 *) Basic restructuring to introduce the MPM concept; includes various
4552 changes to the module API... better described by
4553 docs/initial_blurb.txt. [Dean Gaudet]
4555 Changes with Apache pthreads
4557 *) New buff option added: BO_TIMEOUT. It describes the timeout for
4558 buff operations (generally over a network).
4559 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
4561 *) Created http_accept abstraction. Added 4 new functions (not exported):
4562 init_accept(), begin_accepting_requests(), get_request(),
4563 stop_accepting_requests() [Bill Stoddard]
4565 *) Fix to ap_rprintf call that allows mod_info to work properly.
4566 [James Morris <jmorris@intercode.com.au>]
4568 *) user and ap_auth_type fields were moved from connection_rec to
4569 request_rec. [Ryan Bloom]
4571 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
4572 needed in a threaded server.
4574 *) Initial pthread implementation from from Dean's apache-nspr code.
4575 [Bill Stoddard, Ryan Bloom]
4578 Changes with Apache 1.3.9
4580 *) Remove bogus error message when a redirect doesn't set Location.
4581 Instead, use an empty string to avoid coredump if the error message
4582 was supposed to include a location. [Roy Fielding]
4584 *) Don't allow configure to include mod_auth_digest unless it is
4585 explicitly requested, even if the user asked for all modules.
4588 *) Translate module names to dll names for OS/2 so that they are no more
4589 than 8 characters long and have an extension of "dll" instead of "so".
4592 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
4593 Fix test-compile check to check for randbyte instead of trand32.
4594 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
4595 and tweak to make Amaya happier. [Ronald Tschalär]
4597 *) Ensure that the installed expat include files are world readable,
4598 just like the other header files. [Martin Kraemer]
4600 *) Fixed generated AddModule adjustments in APACI's `configure' script
4601 in order to allow (new) modules like mod_vhost_alias to be handled
4602 correctly (which was touched by the adjustments for mod_alias).
4603 [Ralf S. Engelschall]
4605 *) For binary builds, add -R flag to apachectl to work around the lack of
4606 an absolute path to the ./libexec directory where the libhttp.ep file
4607 is needed for SHARED_CORE architectures. [Randy Terbush]
4609 *) WIN32: Create the CGI script process as DETACHED. This may solve the
4610 problem observed by some Win95/98 users where they get CGI script
4611 output sent to the console. [Bill Stoddard]
4613 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
4614 routines are now called ap_base64* and are 'plain' (i.e., no
4615 pool access or anything clever). Inside util.c the routines acting
4616 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
4617 The oddly named ap_uuencode(), ap_uudecode() are kept around for
4618 now but deprecated. [dirkx]
4620 *) Clean up the base64 and SHA1 additions and make sure they are
4621 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
4622 files. [Roy Fielding]
4624 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
4625 checking. Allow compiling on VS 6.0. [Randy Terbush]
4627 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
4629 *) Use TestCompile to search for the truerand library (rather than blindly
4630 assuming its existence). If it is not found, complain (but do not
4631 exit - yet). [Martin Kraemer]
4633 *) We forgot to add the new exported function names to
4634 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
4636 *) Add description of -T command-line option to usage().
4637 [Ralf S. Engelschall]
4639 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
4640 searched only AFTER libap has been searched, because libap needs
4641 some symbols from libos. [Martin Kraemer]
4643 *) Fix conflict with original mod_digest related to the symbol of the
4644 module dispatch list (which has to be unique for DSO and follow the
4645 usual conventions for the installation procedure).
4646 [Ralf S. Engelschall]
4648 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
4649 for other platforms as well. [Martin Kraemer]
4651 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
4652 types by AP_LONG and replace reference to renamed variable 'ubuf'
4653 by 'buffer'. [Martin Kraemer]
4655 Changes with Apache 1.3.8 [not released]
4657 *) Flush the output buffer immediately after sending an error or redirect
4658 response, since the result may be needed by the client to abort a
4659 long data transfer or restart a series of pipelined requests.
4660 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
4662 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
4663 [Ian Turner <iant@sequent.com>] PR#4735
4665 *) Local struct mmap in http_core.c conflicted with system structure
4666 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
4668 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
4669 [Ronald Tschalär <ronald@innovation.ch>]
4671 *) Fix a memory leak where the module counts were getting messed
4672 up across restarts. [David Harris <dharris@drh.net>]
4674 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
4675 properly in mod_access.
4676 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
4678 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
4679 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
4681 *) PORT: Support for compaq/tandem/com.
4682 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
4684 *) Added SHA1 password encryption support to easy migration from
4685 Netscape servers. See support/SHA1 for more information.
4686 Caused the separation of ap_md5.c into md5, sha1 and a general
4687 ap_checkpass.c with just a validate_passwd routine. Added a
4688 couple of flags to support/htpasswd. Some reuse of the to64()
4689 function; hence renamed to ap_to64().
4690 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
4692 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
4693 with ASCII/EBCDIC conversions in "ident" query.
4694 [David McCreedy <McCreedy@us.ibm.com>]
4696 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
4697 Change "Power Macintosh" to Power* so if uname prints "Power Book"
4698 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
4700 *) Fix SIGSEGV on some systems because the Vary fix below included
4701 a call to table_do with a variable argument list that was not
4702 NULL terminated. Replaced with better implementation. [Roy Fielding]
4704 Changes with Apache 1.3.7 [not released]
4706 *) The "Vary" response header field is now sanitised right before
4707 the header is sent back to the client. Multiple "Vary" fields
4708 are combined, and duplicate tokens (e.g., "Vary: host, host" or
4709 "Vary: host, negotiate, host, accept-language") are reduced to
4710 single instances. This is a better solution than the force-no-vary
4711 one (which is still valid for clients that can't cope with Vary
4712 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
4714 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
4716 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
4717 least on Linux and FreeBSD for now.
4720 *) Win32: More apache -k restart work. Restarts are now honored
4721 immediately and connections in the listen queue are -not- lost.
4722 This is made possible by the use of the WSADuplicateSocket()
4723 call. The listeners are opened in the parent, duplicated, then
4724 the duplicates are passed to the child. The original listen sockets
4725 are not closed by the parent across a restart, thus the listen queue
4727 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4729 *) Fix handling of case when a client has sent "Expect: 100-continue"
4730 and we are going to respond with an error, but get stuck waiting to
4731 discard the body in the pointless hope of preserving the connection.
4732 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
4734 *) Fix 'configure' to work correctly with SysV-based versions of
4735 'tr' (consistent with Configure's use as well). [Jim Jagielski]
4737 *) apxs: Add "-S var=val" option which allows for override of CFG_*
4738 built-in values. Add "-e" option which works like -i but doesn't
4739 install the DSO; useful for editing httpd.conf with apxs. Fix
4740 editing code so that multiple invocations of apxs -a will not
4741 create duplicate LoadModule/AddModule entries; apxs can now be
4742 used to re- enable/disable a module. [Wilfredo Sanchez]
4744 *) Win32: Update the server to use Winsock 2. Specifically, link with
4745 ws2_32.lib rather than wsock32.lib. This gives us access to
4746 WSADuplcateSocket() in addition to some other enhanced comm APIs.
4747 Win 95 users may need to update their TCP/IP stack to pick up
4748 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
4749 [Bill Stoddard stoddard@raleigh.ibm.com]
4751 *) Win32: Redirect CGI script stderr (script debug info) into the
4752 error.log when CGI scripts fail. This makes Apache on Win32
4753 behave more like Unix.
4754 [Bill Stoddard stoddard@raleigh.ibm.com]
4756 *) Fixed `httpd' usage display: -D was missing.
4757 [Ralf S. Engelschall] PR#4614
4759 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
4760 [Ralf S. Engelschall] PR#4561, PR#4562
4762 *) OS/2: Fix problem with accept lock semaphores where server would die with
4763 "OS2SEM: Error 105 getting accept lock. Exiting!"
4764 [Brian Havard] PR#4505
4766 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
4767 [Randy Terbush <randy@covalent.net>]
4769 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
4770 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
4772 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
4773 command potentially _is_ GCC. [Ralf S. Engelschall]
4775 *) Fix apxs build issues on AIX
4776 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
4778 *) DocumentRoot Checking: Under previous versions, when Apache
4779 first started up, it used to do a stat of each DocumentRoot to
4780 see if it existed and was a directory. If not, then an error
4781 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
4782 does not exist, you will get error messages in error_log. If
4783 the '-t' command line option is used (to check the configuration)
4784 the check of DocumentRoot IS performed. An additional command
4785 line option, '-T', has been added if you want to avoid the
4786 DocumentRoot check even when checking the configuration.
4789 *) Win32: The query switch "apache -S" didn't exit after showing the
4790 vhost settings. That was inconsistent with the other query functions.
4791 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
4793 *) Win32: Changed behaviour of apache -k restart.
4794 Previously, the server would drain all connections in the stack's
4795 listen queue before honoring the restart. On a busy server, this
4796 could take hours. Now, a restart is honored almost immediately.
4797 All connections in Apache's queues are handled but connections in
4798 the stack's listen queue are discarded. Restart triggered by
4799 MaxRequestPerChild is unchanged.
4800 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4802 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
4803 the accept loop. Good for a 5% performance boost. Cleaned up
4804 parent/child process management code.
4805 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4807 *) Added ceiling on file size for memory mapped files.
4808 [John Giannandrea <jg@meer.net>] PR#4122
4810 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
4811 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
4812 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
4814 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
4815 use this at least for Expat. [Ralf S. Engelschall]
4817 *) Allow .module files to specify libraries with Lib:.
4820 *) Allow SetEnvIf[NoCase] to test environment variables as well
4821 as header fields and request attributes. [Ken Coar]
4823 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
4824 content-types are "text/html;parameters". PR#4524 [Ken Coar]
4826 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
4827 never accepted into any standard, and it opens up certain DoS
4828 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
4830 *) TestCompile updated. We can now run programs and output the
4831 results during the Configure process. [ Jim Jagielski]
4833 *) The source is now quad (long long) aware as needed. Specifically,
4834 the Configure process determines the correct size of off_t and
4835 *void. When the OS/platform/compiler supports quads, ap_snprintf()
4836 provides for the 'q' format qualifier (if quads are not available,
4837 'q' is silently "demoted" to long). [Jim Jagielski]
4839 *) When the username or password fed to htpasswd is too long, include the
4840 size limit in the error message. Also report illegal characters
4841 (currently only ':') in the username. Add the size restrictions
4842 to the man page. [Ken Coar]
4844 *) Fixed the configure --without-support option so it doesn't result in
4845 an infinite loop. [Marc Slemko]
4847 *) Piped error logs could cause a segfault if an error occured
4848 during configuration after a restart.
4849 [Aidan Cully <aidan@panix.com>] PR#4456
4851 *) If a "Location" field was stored in r->err_headers_out rather
4852 than r->headers_out, redirect processing wouldn't find it and
4853 the server would core dump on ap_escape_html(NULL). Check both
4854 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
4855 if Location isn't set. [Doug MacEachern, Ken Coar]
4857 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
4858 of the Expat 1.0.2 distribution. [Greg Stein]
4860 *) Replace regexec() calls with calls to a new API stub function
4861 ap_regexec(). This solves problems with DSO modules which use the regex
4862 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
4864 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
4865 environment variables can be set according to the protocol version
4866 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
4868 *) Add DSO support for OpenStep (Mach 4.2) platform.
4869 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
4871 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
4872 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
4874 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
4875 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
4877 *) Better DSO flags recognition on NetBSD platforms using ELF.
4878 [Todd Vierling <tv@pobox.com>] PR#4310
4880 *) Always log months in english format for %t in mod_log_config.
4881 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
4883 *) Support for server-parsed and multiview-determined ReadmeName and
4884 HeaderName files in mod_autoindex. Removed the restriction on
4885 "/"s in ReadmeName and HeaderName directives since the *sub_req*
4886 routines will deal with the access issues. (It's now possible to
4887 have {site|group|project|customer|...} wide readmes and headers.)
4888 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
4891 *) When stat() fails, don't assume anything about the contents of
4892 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
4894 *) It's OK for a semop to return EINTR, just loop around and try
4895 again. [Dean Gaudet]
4897 *) Fix configuration engine re-entrant hangups, which solve a
4898 handful of problems seen with mod_perl <Perl> configuration sections
4899 [Salvador Ortiz Garcia <sog@msg.com.mx>]
4901 *) Mac OS and Mac OS X Server now use the appropriate custom layout
4902 by default when building with APACI; allow for platform-specific
4903 variable defaults in configure. [Wilfredo Sanchez]
4905 *) Do setgid() before initgroups() in http_main; some platforms
4906 zap the grouplist when setgid() is called. This was fixed in
4907 suexec earlier, but the main httpd code missed the change.
4908 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
4910 *) Add recognition of .tgz as a gzipped tarchive.
4911 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
4913 *) mod_include's fsize/flastmod should allow only relative paths, just
4914 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
4916 *) OS/2: Add support for building loadable modules using DLLs.
4919 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
4922 *) Fix minor but annoying bug with the test for Configuration.tmpl
4923 being newer than Configuration so that it is less likely to fail
4924 when using APACI and shadow sources. [Wilfredo Sanchez]
4926 *) PORT: Add initial support for Mac OS (versions 10.0 and
4927 greater). Use Mac OS X Server layout for now. Clean up dyld code
4928 in unix/os.c, and don't install the dyld error handlers, which
4929 are no longer needed in Mac OS. [Wilfredo Sanchez]
4931 *) Rename Rhapsody layout to "Mac OS X Server". Change install
4932 locations to appropriate ones for user-built (as opposed to
4933 system) installs. [Wilfredo Sanchez]
4935 *) Modify mod_autoindex's handling of AddDescription so that the
4936 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
4938 *) Add functionality to the install-bindist.sh script created by
4939 binbuild.sh to use tar when copying distribution files to the
4940 serverroot. This allows upgrading an existing installation
4941 without nesting the new distribution in the old.
4943 install-bindist.sh now detects the local perl5 path to install
4944 apxs and dbmmanage with proper path to perl interpreter.
4946 Add an install-binsupport target which copies the source files
4947 for apxs and dbmmanage to bindist to allow these scripts to
4948 be properly installed relative to the destination serverroot.
4949 [Randy Terbush, Covalent Technologies, randy@covalent.net]
4951 *) Fix intermittent SEGV in ap_proxy_cache_error() in

4963 *) Force the LANG envariable to the known state of "C" so that we
4964 have assurance about how string manipulators (e.g., tr) will
4965 function. [Ken Coar] PR#1630
4967 *) Add a directive to allow customising of the tracking cookie name.
4968 [Ken Coar] PR#2921, 4303
4970 *) Add "force-no-vary" envariable to allow servers to work around
4971 clients that choke on "Vary" fields in the response header.
4972 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
4974 *) Fixed a bug in mod_dir that causes a child process will infinitely
4975 recurse when it attemps to handle a request for a directory wnd the
4976 value of the DirectoryIndex directive is a single dot. Also likely
4977 to happen for anyother values of DirectoryIndex that will map back

5120 ap_default_type() function to determine the configured type.
5121 This allows for special configurations like
5122 <Directory proxy:ftp://some.host>
5123 DefaultType gargle/blurb
5125 Additionally, add the Content-Encoding: header to FTP proxy replies
5126 when the encoding is defined (by the AddEncoding directive).
5127 Because it was missing, it was almost impossible to browse compressed
5128 files using the FTP proxy (works now perfectly in Communicator).
5129 The ftp proxy now also returns the Date: and Server: header lines (if not
5130 much else... This code is "somewhat" broken) like normal requests do.
5133 *) Be more smart in APACI's configure script when determining the UID/GID
5134 for User/Group directives and use the determined UID/GID to initialize
5135 the permissions on the proxycachedir.
5136 [Dirk-Willem van Gulik, Ralf S. Engelschall]
5138 *) Changed the forking-prior-to-cleanup in the proxy module to first
5139 check wether it actually needs to collect garbage. This reduces
5140 the number of fork()s from one/request to just the odd one an hour.
5141 [Dirk-Willem van Gulik]
5143 *) Added proxy, auth and header support to src/support/ab.c. Added a
5144 README file to src/support/
5145 [Dirk-Willem van Gulik]
5147 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
5148 [Ralf S. Engelschall] PR#4050
5150 *) Add support for DSO module compilation on BSD/OS 3.x.
5151 [Randy Terbush, Covalent Technologies]
5153 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
5154 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
5155 option) were substituted with $(TARGET).conf, etc. Same for other strings
5156 with dots where the dot wasn't matched as plain text.
5157 [Ralf S. Engelschall]

5164 Changes with Apache 1.3.6
5166 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
5168 Changes with Apache 1.3.5 [not released]
5170 *) M_INVALID needed a value within the scope of METHODS so that unknown
5171 methods can be access controlled. [Roy Fielding] PR#3821
5173 *) Added PassAllEnv; makes server's entire environment available
5174 to CGIs and SSIs executed within directive's scope. [Ken Coar]
5176 *) ap_uuencode() always added two trailing '='s and encoding of
5177 8 bit characters on a machine with signed char may produced
5178 incorrect results. Additionally ap_uuencode() should now
5179 work correctly on EBCDIC platforms.
5180 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
5182 *) WIN32: Binary installer now runs the configuration DLL before
5183 the reboot prompt (which is only given if MSVCRT.DLL system
5184 DLL is new or updated). This should avoid the configuration
5185 directory being empty after installation. [Paul Sutton]
5186 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
5188 *) WIN32: Binary installer now creates Start menu options to start
5189 and stop Apache as a console application and to uninstall
5190 the Apache service on NT. [Paul Sutton] PR#3741
5192 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
5194 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
5195 have been reported with flock() locking (probably related to kernel
5196 version). [Dean Gaudet] PR#2723, 3531
5198 *) Using APACI, the main config file (usually httpd.conf) was
5199 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
5200 <wsanchez@apple.com>]
5202 *) PORT: AIX does not require the SHARED_CODE "hack"
5203 [Ryan Bloom <rbb@raleigh.ibm.com>]
5205 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
5206 avoidance code added in 1.3.3.
5207 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
5209 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
5210 for 8-bit safeness. [Dean Gaudet]
5212 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
5213 because SPARCs have a small machine-specific maximum size for the Global
5214 Offset Table which is often exceeded when compiling one of the larger
5215 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
5217 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
5218 DSO/DLL section because it's a directive from mod_status and isn't
5219 available before the DLL of mod_status is loaded.
5220 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
5222 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
5223 continuation facility in Apache's configuration files which could
5224 lead to a buffer overflow situation.
5225 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
5227 *) Make documentation and error messages of APACI's --activate-module=FILE
5228 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995

5231 really support all future gcc versions >= 2.7 until we know more.
5232 [John Tobey <jtobey@banta-im.com>] PR#3983
5234 *) Let APACI's configure script correctly complain for unknown --enable-XXX
5235 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
5237 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
5238 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
5239 possible buffer overflows. [Ralf S. Engelschall]
5241 *) Remove no longer used non-API function ap_single_module_init().
5242 [Ralf S. Engelschall]
5244 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
5247 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
5248 to make platform installations easier. [Wilfredo Sanchez]
5250 *) In configure, do not append the target name to the directory path if
5251 the path already contains "apache". [Ralf S. Engelschall]
5253 *) SIGPIPE is now ignored by the server core. The request write routines
5254 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
5255 correctly check for output errors and mark the connection as aborted.
5256 Replaced many direct (unchecked) calls to ap_b* routines with the
5257 analogous ap_r* calls. [Roy Fielding]
5259 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
5260 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
5261 Furthermore map lookups for non-existent keys are now cached as well.
5262 Additionally "txt" maps are now parsed with simple string functions
5263 instead of using ap_pregcomp(). As a side effect a bug that prevented
5264 the usage of keys containing the "," character was fixed.
5265 The changes drastically improve the performance when large rewrite maps
5267 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
5269 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
5270 other than GET, and const'd the definition of method in request_rec.
5273 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
5275 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
5276 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
5278 *) Add %V to mod_log_config, this logs the hostname according to the
5279 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
5280 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
5282 *) Add support for \n and \t to mod_log_config, can be used to produce
5283 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
5285 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
5287 *) Added informative error messages for failed munmap() and fseek() calls
5288 in http_core.c. [John Bley, Roy Fielding]
5290 *) Added some informative error messages for some failed malloc()
5291 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
5293 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
5294 is removed. This allows <Directory proxy:*> directives to work and
5295 prevents invalid requests from killing the process.
5296 [Brian Havard <brianh@kheldar.apana.org.au>]
5298 *) Reorganised FAQ document.
5299 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
5301 *) src/support/: The ApacheBench benchmark program was overhauled by
5302 David N. Welton: you can now have it generate an HTML TABLE, presumably
5303 for integration into other HTML sources. David updated the ab man page
5304 as well and added some missing descriptions. Thanks!
5305 [David N. Welton <davidw@prosa.it>]
5307 *) Win32: The filename validity checker now allows filenames containing
5308 characters in the range 0x80 to 0xff (for example accented characters).
5309 [Paul Sutton] PR#3890
5311 *) Added conditional logging based upon environment variables to
5312 mod_log_config. mod_log_referer and mod_log_agent
5313 are now deprecated. [Ken Coar]
5315 *) Allow apache acting as a proxy server to relay the real
5316 reason of a failure to a client rather than the "internal
5317 server error" it does currently. The general exposure mechanism
5318 can be triggered by any module by setting the "verbose-error-to"
5319 note to "*"; this allows more than just proxy errors to be exposed.
5320 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
5322 *) Moved man pages for ab and apachectrl to section 8.
5323 [Wilfredo Sanchez, Roy Fielding]
5325 *) Added -S option to install.sh so that options can be passed to
5326 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
5328 *) Tweak modules Makefile generated by Configure so that it handles
5329 the test case of no modules being selected. [chaz@reliant.com]
5331 *) Added a <LimitExcept method ...> sectioning directive that allows
5332 the user to assign authentication control to any HTTP method that
5333 is *not* given in the argument list; i.e., the logical negation
5334 of the <Limit> directive. This is particularly useful for controlling
5335 access on methods unknown to the Apache core, but perhaps known by
5336 some module or CGI script. [Roy Fielding, Tony Finch]
5338 *) Prevent apachectl from complaining if the PIDFILE exists but
5339 does not contain a process id, as might occur if the server is
5340 being rapidly restarted. [Wilfredo Sanchez]
5342 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
5344 *) Entity tag comparisons for If-Match and If-None-Match were not being
5345 performed correctly -- weak tags might cause false positives. Also,
5346 strong comparison wasn't properly enforced in all cases.
5347 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
5349 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
5352 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
5353 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
5355 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
5356 to util.c for parsing an HTTP header field value to extract the next
5357 list item, taking into account the possible presence of nested comments,
5358 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
5359 insignificant whitespace and lowercases non-quoted tokens.
5360 [Roy Fielding] PR#2065
5362 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
5363 code different from 500. This allows the proxy to, e.g., return
5364 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
5366 *) Fix ordering of language variants for the case where the traditional
5367 negotiation algorithm is being used with multiple language variants
5368 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
5370 *) Do not round the TCN quality calculation to 5 decimal places,
5371 unlike RFC 2296, because the calculation might need 12 decimal places
5372 to get the right result. [Roy Fielding]
5374 *) Remove unused code to disable transparent negotiation when
5375 negotiating on encoding only, as we now handle encoding too
5376 (though this is nonstandard for TCN), remove charset=ISO-8859-1
5377 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
5378 some debugging statements within mod_negotiation. [Koen Holtman]
5380 *) Fixed a rare memory corruption possibility in mod_dir if the index
5381 file is negotiable and no acceptable variant can be found.
5382 [Dean Gaudet, Roy Fielding, Martin Kraemer]
5384 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
5385 searching the Win32 registry for script interpreters.
5388 *) Win32: The compiled-in default filename for the error log is now
5389 error.log, which matches the default in the distributed httpd.conf.
5392 *) Win32: Any error messages from -i or -u command line options are now
5393 displayed on the console output rather than sent to the error log.
5394 Also the "Running Apache..." message is not output unless Apache is
5395 going to serve requests. [Paul Sutton]
5397 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
5398 and use a private significator ('$apr1$') to mark passwords as
5399 being smashed with our own algorithm. Also abstract the password
5400 checking into a new ap_validate_password() routine. [Ken Coar]
5402 *) Win32: The filename validity checker now allows "COM" but refuses
5403 access to "COM1" through "COM4". This allows filenames such
5404 as "com.name" to be served. [Paul Sutton] PR#3769.
5406 *) BS2000: Adapt to the new ufork() system call interface which will
5407 make subtasking easier on the OSD/POSIX mainframe environment.
5410 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
5411 ap_compat.h. [David White <david@persimmon.com>] PR#3725
5413 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
5414 use `.db' instead of `.pag' not only for FreeBSD, but also when
5415 the NDBM library looks like Berkeley-DB based.
5416 [Ralf S. Engelschall] PR#3773
5418 *) Add ability to handle DES or MD5 authentication passwords.
5419 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
5421 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
5423 *) SECURITY: Avoid some buffer overflow problems when escaping
5424 quoted strings. (This overflow was on the heap and we believe
5425 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
5427 *) Let src/Configure be aware of CFLAGS options starting with plus
5428 signs as it's the case for the HP/UX compiler.
5429 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
5431 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
5432 and check to see if the tar we wind up with supports '-h'.
5433 [Jim Jagielski] PR#3671
5435 *) A consistent and conservative style for all shell scripts has been
5436 implemented. Basically, all shell string tests use the traditional
5437 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
5438 to protect against bare null variable strings (ie: wrapping both
5439 sides with double quotes and prepending 'x'). 'x' was chosen
5440 because it's more universal and hopefully easier for old shell
5441 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
5444 *) The status module now prints out both the main server generation as
5445 well as the generation of each process. Also, the vhost info is
5446 printed with '?notable'. [Jim Jagielski]
5448 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
5449 and this makes its functions available to things in src/support.
5452 Changes with Apache 1.3.4
5454 *) Renamed macros status_drops_connection to ap_status_drops_connection
5455 and vestigial scan_script_header to ap_scan_script_header_err,
5456 mostly for aesthetic reasons. [Roy Fielding]
5458 *) The query switch "httpd -S" didn't exit after showing the
5459 vhost settings. That was inconsistent with the other query functions.
5462 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
5463 filename to the end of the STANDARD_MODULE_STUFF. Its
5464 presence at the beginning prevented reporting of the filename
5465 for modules compiled before 1 January 1999. [Ken Coar]
5467 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
5468 to detect and prevent access to special DOS device file names.
5469 [Paul Sutton, Ken Parzygnat]
5471 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
5472 and Makefile_win32_debug.txt (debug build) that work on Win95.
5473 Run each of the following from the src directory:
5474 nmake /f Makefile_win32.txt # compiles normal build
5475 nmake /f Makefile_win32.txt install # compiles and installs
5476 nmake /f Makefile_win32.txt clean # removes compiled junk
5477 nmake /f Makefile_win32_debug.txt # compiles debug build
5478 nmake /f Makefile_win32_debug.txt install
5479 nmake /f Makefile_win32_debug.txt clean
5482 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
5483 to build binary distributions. [Lars Eilebrecht]
5485 *) IndexOptions SuppressColumnSorting only turned off making
5486 the column headers anchors; you could still change the display
5487 order by manually adding a '?N=A' or similar query string to the
5488 URL. Now SuppressColumnSorting locks in the sort order so
5489 it can't be overridden this way. [Ken Coar]
5491 *) Added IndexOrderDefault directive to supply a default sort order
5492 for FancyIndexed directory listings. [Ken Coar] PR#1699
5494 *) Change the ap_assert macro to a variant that works on all platforms.
5495 [Richard Prinz <richard.prinz@cso.net>] PR#2575
5497 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
5498 search for an underscore on dlsym() (as it's already the case
5499 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
5501 *) Small fix for mod_env.html: The module was documented as to be _not_
5502 compiled into Apache per default, although it _IS_ compiled into
5503 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
5505 *) Instead of fixing a bug in the generation procedure for config.status (a
5506 backslash was missing) we remove the bug together with it's complete
5507 context because the special cases of the past can now no longer occur
5508 because of the recent magic for the --with-layout default.
5509 [Ralf S. Engelschall] PR#3590
5511 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
5512 making sure the src/support/ tools are _forced_ to be build last (they
5513 depend on other libraries).
5514 [Markus Theissinger <markus.theissinger@gmx.de>]
5516 *) Fix installation procedure: Now that os-inline.c is actually used (a
5517 recently fixed bug prevented this) we need to also install os-include.c
5518 in addition to os.h into the PREFIX/include/ location or building of
5519 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
5521 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
5522 allow us to distinguish between a garbled DSO (or even a file which isn't
5523 an Apache module DSO at all) and a DSO which doesn't match the current
5524 Apache API. [Ralf S. Engelschall] PR#3152
5526 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
5527 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
5528 match case insensitive (this especially avoids nasty patterns like
5529 `[tT][eE][sS][tT]'). Second two additional internal map functions
5530 `escape' and `unescape' were added which can be used to escape/unescape
5531 to/from hex-encodings in URLs parts (this is especially useful in
5532 combination with map lookups).
5533 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
5535 *) Renamed the macro escape_uri() to ap_escape_uri() which was
5536 forgotten (because it was a macro) in the symbol renaming process.
5537 [Ralf S. Engelschall]
5539 *) Fix some inconsistencies related to the scopes of directives. The only
5540 user visible change is that the directives `UseCanonicalName' and
5541 `ContentDigest' now use the (more correct) `Options' scope instead of
5542 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
5544 *) Using DSO, the Server token was being mangled. Specifically, the
5545 module's token was being added first before the Apache token. This
5546 has been fixed. [Jim Jagielski]
5548 *) Major overhaul of mod_negotiation.c, part 2.
5549 - properly handle "identity" within Accept-Encoding.
5550 - allow encoded variants in RVSA negotiation and let them appear in
5551 the Alternates field using the non-standard "encoding" tag-list.
5552 - fixed both negotiation algorithms so that an explicitly accepted
5553 encoding is preferred over no encoding if "identity" is not
5554 included within Accept-Encoding.
5555 - added ap_array_pstrcat() to alloc.c for efficient concatenation
5556 of large substring sequences.
5557 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
5560 *) Major overhaul of mod_negotiation.c, part 1.
5561 - cleanups to mod_negotiation comments and code structure
5562 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
5563 support for everything in the upcoming HTTP/1.1
5564 revision (draft-ietf-http-v11-spec-rev-06.txt).
5565 - language tag matching also handles tags with more than 2
5567 - empty Accept, Accept-Language, Accept-Charset headers are
5568 processed correctly; previously an empty header would make all
5569 values acceptable instead of unacceptable.
5570 - allowed for q values in Accept-Encoding
5571 - added support for transparent content negotiation (rfc2295 and
5572 rfc2296) (though we do not implement all features in these drafts,
5573 e.g. no feature negotiation). Removed old experimental version.
5574 - implemented 'structured entity tags' for better cache correctness
5575 (structured entity tags ensure that caches which can deal with Vary
5576 will (eventually) be updated if the set of variants on the server
5578 - this involved adding a vlist_validator element to request_rec
5579 - this involved adding the ap_make_etag() function to the global API
5580 - modified guessing of charsets used by Apache negotiation algorithm
5581 to guess 'no charset' if the variant is not a text/* type
5582 - added code to sort multiviews variants into a canonical order so that
5583 negotiation results are consistent across backup/restores and mirrors
5584 - removed possibility of a type map file resolving to another type map
5585 file as its best variant
5586 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987

5610 Now SHELL_PATH is started in these cases. [Martin Kraemer]
5612 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
5615 *) Update APXS manual page: some -q option arguments were missing
5616 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
5618 *) Cleanup the command line options: `-?' was documented to show
5619 the usage list but does it with an error because `?' is not a valid
5620 command. OTOH a lot of users expect `-h' to print such a usage list and
5621 instead are annoyed for ages by our huge unreadable list of directives.
5622 So we now changed the command line options this way:
5624 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
5625 very similar to the popular linker option.
5627 Intent: while -l gives the small list of modules, -L now gives the
5628 large list of directives implemented by these modules. This is also
5629 consistent with -v (short version info) and -V (large version info).
5631 Intent: it's now the expected option ;-)
5632 The manual page was adjusted accordingly.

5635 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
5636 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
5638 *) Removed recently introduced bugs and disfigurements in APACI:
5639 o fixed argument line processing: using $args was broken: It was not
5640 initialized and using args="$args $apc_option" and even args="$args
5641 \"$apc_option\"" fails in the second processing round for any arguments
5642 containing whitespaces. The only correct way is to use the construct
5643 "$@" (but not possible here) or iterate _both_ times over the implicit
5644 argument line (no argument to for-loop) which is what we now use.
5645 o make --with-layout=Apache the default without creating
5646 redundancy (copying the --with-layout block in the argument parsing
5647 loop). We achieve this by using the "$@" construct together with the
5648 `set' command to prepend --with-layout=Apache to the command line in
5649 case --with-layout is not used.
5650 o fixed auto-suffix handling now that config.layout exists.
5651 Paths which are auto-suffixed are marked with a trailing plus sign in
5652 config.layout and every path now can be marked this way (not only the
5653 four paths for which we do it currently). Additionally the suffix is
5654 no longer a static one. Instead it's now `/<target>' where <target> is
5655 the argument of the --target option or per default `httpd'.
5656 o allow also tabs (and only spaces) where we match whitespaces
5657 o various fixes and cleanups related to used shell coding style
5658 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
5659 o trimmed output of --help to fit into 80 columns

5662 *) Added two new core API functions, ap_single_module_configure() and
5663 ap_single_module_init(), which are now used by mod_so to configure a module
5664 after loading. [Ralf S. Engelschall]
5666 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
5667 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
5668 of ap_config.h to allow serialized accept for multiport listens.
5669 [Roy Fielding, Curt Sampson] PR#3120

5672 of ap_config.h that would skip several defines if DEFAULT_GROUP
5673 was overridden. [Roy Fielding]
5675 *) PORT: The I86 version of DGUX has support for strncasecmp and
5676 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
5678 *) Fix ordering of definitions in ap_config.h so that ap_inline is
5679 defined before it might be used. [Victor Khimenko]
5681 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
5682 [Tom Serkowski <tks@bsdi.com>] PR#3453
5684 *) Make generation of src/Configuration.apaci more robust: It failed to
5685 differenciate between modules when one module name was a postfix of
5686 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
5687 just XXX (think about totally non-standard names like "apache_ssl", too).
5688 [Ralf S. Engelschall] PR#3380
5690 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
5691 since 1.3b7) and make whitespace handling more robust (it failed horrible
5692 when whitespaces were present in the arguments of -D options).
5693 [Ralf S. Engelschall] PR#3240
5695 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
5696 creates an external package shadow tree in DIR before the local build
5697 shadow tree is generated under DIR. This way one can have the extracted
5698 Apache distribution tree read-only on NFS or CDROM and still build Apache
5699 from these sources. An automatically triggered VPATH-like mechanism is
5700 provided through the TOP variable, too.

5703 *) Fix negotiation so that a Vary response header is correctly
5704 generated when, for a particular dimension, variants only vary
5705 in having or not having a value for that dimension. [Paul Sutton]

5708 unencoded variant if the user-agent explicitly says it can
5709 accept that encoding. Previously we always preferred the unencoded

5713 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
5714 and the usage page was inconsistent with the functionality and manpage.
5715 [Ralf S. Engelschall]
5717 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
5718 They can occur multiple times and their arguments (`xxx') are passed AS
5719 IS to the compiler/linker command. [Ralf S. Engelschall]
5721 *) Fixed possible (but harmless in practice) bug in the DBM lookup
5722 procedure of mod_rewrite: very long keys were truncated.
5723 [Ralf S. Engelschall]
5725 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
5726 identifier, currently "Apache" and "GNU" are pre-defined in the file
5727 config.layout. Custom layouts are possible by using FILE:ID as the
5728 argument where the layout ID is taken from FILE.
5730 The config.layout file consists of <Layout ID>..</Layout> sections
5731 where inside those sections "path_variable: path_value" pairs can be
5732 specified. These lines are converted to path_variable='path_value'.
5734 *) Add a DefaultLanguage directive so that files missing a language
5735 extension (e.g., .fr, .de) can be labelled as being some other
5736 default language. DefaultLanguage can appear in <Directory> and
5737 <Files> containers as well as .htaccess files. [Paul Sutton]
5740 *) Fix TARGET configuration when configuring and installing using
5741 APACI configure. TARGET now defines the basename of the configuration
5742 file, startup script, manual page, etc. log_error_core() now reports
5743 the server binary name given by argv[0]. TARGET can now also be defined
5744 with --target=TARGET parameter passed to APACI configure.

5747 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
5748 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

5767 notice to the error log. It is not possible to send a 401 response
5768 and a redirect at the same time. [Lars Eilebrecht]
5770 *) Fallback to native compilers for IRIX-32 platform. It seems that
5771 a gcc 2.8.1 compiled apache is logging client addresses with all
5772 bits set (255.255.255.255). This is the second such problem caused
5773 by gcc 2.8.1 compiler. The first being broken semaphore locking.
5776 *) Updated mime.types to reflect current Internet media types
5777 and include a URL to the registry.

5780 *) SECURITY: Do a more complete check in mod_include to avoid
5781 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
5783 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
5784 used to set the document root directory (DOC_ROOT) and the suexec
5785 logfile (LOG_EXEC), respectively. Additionally the --layout option
5786 was changed to show more information about the suEXEC setup.

5789 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
5790 and 507 (Insufficient Storage) for use by third-party modules.

5794 modules, Limit, and Script directives. That includes PATCH,
5795 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
5796 Improved mod_actions.c so that it can use any of the methods
5797 defined in httpd.h. Added ap_method_number_of(method) for

5821 the interpreter and the Win32 error code returned. [Marc Slemko]
5823 *) Disable sending of error-notes on a 500 (Internal Server Error) response
5824 since it often includes file path info. Enable sending of error-notes
5825 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
5827 *) http_config.c would respond with 501 (Method Not Implemented) if a
5828 content type handler was specified but could not be found, which
5829 should have been a 500 response. Likewise, mod_proxy.c would responsd
5830 with a 501 if the URI scheme is unrecognized instead of the correct
5831 response of 403 (Forbidden). [Roy Fielding]
5833 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
5834 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]

5837 unavailable, an empty string was printed which was 2 bytes short.
5838 The size and description columns were therefore not aligned correctly.

5846 scoreboard file and avoid a string copy (as well as allow some
5847 further future enhancements). [Harrie Hazewinkel
5848 <harrie.hazewinkel@jrc.it>]
5850 *) Add APACI --permute-module=foo:bar option which can be used to
5851 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
5852 in the Configuration[.apaci] file. Two special and important variants are
5853 supported for the option argument: first BEGIN:foo which permutes module
5854 mod_foo with the begin of the module list, i.e. it `moves' the module to
5855 the begin of the list (gives it lowest priority). And second foo:END
5856 which permutes mod_foo with the end of the module list, i.e. it `moves'
5857 the module to the end of the list (gives it highest priority).

5932 response when we already know the final status, which is mighty
5933 useful for PUT responses that result in 302 or 401. [Roy Fielding]
5935 *) Remove extra trailing whitespace from the getline results as part
5936 of the protocol processing, which is extra nice because it works
5937 between continuation lines, is almost no cost in the normal case
5938 of no extra whitespace, and saves memory. [Roy Fielding]

5941 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
5942 HTTP Extension Framework (510) specifications. Did not add the
5943 WebDAV 424 and 425 codes because they are bogus. We don't use any

6082 *) Fix the recently introduced C header file checking: We now use the C
6083 pre-processor pass only (and no longer the complete compiler pass) to
6084 determine whether a C header file exists or not. Because only this way
6085 we're safe against inter-header dependencies (which caused horrible
6086 portability problems). The only drawback is that we now have a CPP
6087 configuration variable which has to be determined first (we do a similar
6088 approach as GNU Autoconf does here). When all fails the user still has
6089 the possibility to override it manually via APACI or src/Configuration.
6090 As a fallback for the header check itself we can directly check the
6091 existance of the file under /usr/include, too.

6128 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
6129 functions: First all three functions no longer fail on strings containing
6130 "%" chars and second ap_log_printf() no longer does a double-formatting
6131 (instead it directly passes through the message to be formatted to the
6132 real internal formatting function). [Ralf S. Engelschall] PR#2941
6134 *) Allow "Include" directives anywhere in the server config

6140 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
6142 *) mod_expires will now act on content that is not sent from a file
6143 on disk. Previously it would never add an Expires: header to
6144 any response that did not come from a file on disk; the only
6145 case where it still doesn't (and can't) add one for that type of
6146 content is if you are using a modification date based setting.

6161 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
6162 a common problem of (mis-administrated?) IIS servers, make the apache
6163 proxy immune to these errors (and ignore the duplicates, but log
6164 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
6166 *) The <IfModule and <IfDefine block starting directives now only
6167 allow exactly one argument. Previously, the optional negation
6168 character '!' could be separated by whitespace without a syntax
6169 error being reported, albeit defeating the IfModule functionality
6170 (enclosed directives would ALWAYS be executed). By using the
6171 stricter syntax, these hard-to-track errors can be avoided.
6174 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
6175 cause the standalone FancyIndexing directive to logically OR
6176 into any existing IndexOptions settings rather than wiping
6177 them out. [Ken Coar]
6179 *) Changes in ftp proxy: make URL parsing simpler by using the
6181 + Add display of the "current directory" in cases where it's
6182 different from the supplied path (e.g., ftp://user@host/ lives
6183 in /home/user, not in /, therefore clicking on "../" in the
6184 starting directory might send us to /home/).
6185 + When ftp login fails, (esp. when a user name was part of the
6186 URL already), we now return [401 Unauthorized ] to allow the
6187 browser to pop up an authorization dialog. This makes passwords
6188 slightly less visible (they don't appear in the regular log files)
6189 and implements a functionality that other www proxy servers
6193 *) Triggered by the recent "Via:" header changes, the proxy module would
6194 dump core for replies with invalid headers (e.g., duplicate
6195 "HTTP/1.0 200 OK" lines). These errors are now logged and the
6196 core dump is avoided. Also, broken replies are not cached.

6206 *) Replace the inlined information grabbing stuff for the configuration
6207 adjustment feature (no --without-confadjust) with calls to a new helper
6208 script `buildinfo.sh' which is both more flexible and already proofed to
6209 be more robust against platform differences. This mainly fixes the

6231 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
6232 5 to 10 because there are some users out there who always have 5 to 8
6233 variables in one RewriteRule and had to patch mod_rewrite.h for every
6234 release. So 15 should be now more than enough, even for them. (I never
6235 needed more than 4 in my RewriteRules ;-)

6245 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844

6257 compile time, for least astonishment of the user.
6260 *) When READing a request in ExtendedStatus mode, the "old"
6261 vhost, request and client information is not displayed.
6264 *) STATUS is no longer available. Full status information now
6265 run-time configurable using the ExtendedStatus directive.
6268 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
6269 cpu time attacks) in header parsing. Add ap_overlap_tables(),
6270 a function which can be used to perform bulk update operations
6271 on tables in a more efficient manner. [Dean Gaudet]
6273 *) SECURITY: Added compile-time and configurable limits for
6274 various aspects of reading a client request to avoid some simple
6275 denial of service attacks, including limits on maximum request-line
6276 size (LimitRequestLine), number of header fields (LimitRequestFields),
6277 and size of any one header field (LimitRequestFieldsize). Also added
6278 a configurable directive LimitRequestBody for limiting the size of the
6279 request message body. [Roy Fielding]

6282 STATUS not defined. [Jim Jagielski]

6295 ap_scan_script_header_err_core() [Doug MacEachern]
6297 *) The 'status' module will now show the process pid's and their
6298 state even without full STATUS accounting. [Jim Jagielski]
6300 *) Restore the client IP address to the error log messages, this
6301 was lost during the transition from 1.2 to 1.3. Add a new
6302 function ap_log_rerror() which takes a request_rec * and
6303 formats it appropriately. [Dean Gaudet] PR#2661
6305 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
6306 whitespace in input lines -- including within quoted strings.
6308 but leading and trailing whitespace should continue to be
6309 stripped [Martin Kraemer]
6311 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
6312 the ugly use of an env. variable and use command-line args for
6313 alternate $PATH. Make more like advanced 'type's as well.
6316 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
6317 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis

6320 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
6322 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
6323 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
6324 directory was renamed to src/os/os2/ for consistency.
6325 [Brian Havard, Ralf S. Engelschall]
6327 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
6328 files (here modules) against other DSO files (here shared libraries).
6329 This is done by determining a subset of LIBS which can be safely used for
6330 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
6331 disabled for all platforms to avoid problems with this (experimental)
6332 rule. But we provide it now for those people how ran into problems and
6333 want to came out by forcing linking against DSOs.
6334 [Ralf S. Engelschall] PR#2587
6336 *) Fix suEXEC start message: Has to be of `notice' level to really get

6349 lingering_close, thus avoiding a potential TCP reset that would
6350 cause the client to miss the HTTP error response. [Roy Fielding]
6352 *) One more portability fix for APACI shadow tree support: Swap order of awk
6353 and sed in top-level configure script to avoid sed fails on some
6354 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

6412 the read_request error conditions of URI-too-long (414) and
6413 malformed header fields (400). [Roy Fielding] PR#2646
6415 *) Add support for the Max-Forwards: header line required by RFC2068 for
6416 the TRACE method. This allows apache to TRACE along a chain of proxies
6417 up to a predetermined depth. [Martin Kraemer]
6419 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled

6468 *) mod_mmap_static will no longer take action on requests unless at
6469 least one "mmapfile" directive is present in the configuration.
6470 This experimental module has to do some black magic to operate

6599 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
6601 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
6602 also works for OpenBSD 1.x. [Ralf S. Engelschall]
6604 *) PORT: Fix compilation problem on ARM Linux.
6605 [Sam Kington <sam@illuminated.co.uk>] PR#2443
6607 *) Let APACI's configure script determine some configuration parameters
6608 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
6609 remove some of the classical hurdles for new users when setting up
6610 Apache. This is done per default because it is useful for the average
6611 user. Package authors can use the --without-confadjust option to disable
6612 these configuration adjustments.
6613 [Ralf S. Engelschall]
6615 *) Added an EXTRA_DEPS configuration parameter which can be used
6616 to add an extra Makefile dependency for the httpd target, for instance
6617 to external third-party libraries, etc.
6618 [Ralf S. Engelschall]
6620 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
6621 as <IfModule>..</IfModule> sections) which can be used to skip or process
6622 contained commands dependend of ``-D PARAMETER'' options on the command
6623 line. This can be used to achieve logical conditions like <IfDefine
6624 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
6625 and thus especially can be used for conditionally loading DSO-based
6626 modules via LoadModule, etc. [Ralf S. Engelschall]
6628 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
6630 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
6632 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
6633 truncated which forced following HTTP headers to be data in the HTTP
6634 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
6637 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
6638 in top-level configure script to avoid sed fails on some platforms (for
6639 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
6640 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
6642 *) Improve performance of directory listings (mod_autoindex) by comparing
6643 integer keys (last-modified and size) as integers rather than converting
6644 them to strings first. Also use a set of explicit byte tests rather
6645 than strcmp() to check for parent directory-ness of an entry. Oh, and
6646 make sure the parent directory (if displayed) is *always* listed first
6647 regardless of the sort key. Overall performance winnage should be good
6648 in CPU time, instruction cache, and memory usage, particularly for large
6649 directories. [Ken Coar]
6651 *) Add a tiny but useful goody to APACI's configure script: The generation
6652 of a config.status script (as GNU Autoconf does) which remembers the used
6653 configure command and hence can be used to restore the configuration by
6654 just re-running this script or for remembering the configuration between
6656 [Ralf S. Engelschall]
6658 *) Add httpd -t (test) option for running configuration syntax tests only.
6659 If something is broken it complains and exits with a return code
6660 non-equal to 0. This can be used manually by the user to check the Apache
6661 configuration after editing and is also automatically used by apachectl
6662 on (graceful) restart command to make sure Apache doesn't die on restarts
6663 because of a configuration which is now broken since the last (re)start.
6664 This way `apachectl restart' can be used inside cronjobs without having
6665 to expect Apache to be falling down. Additionally the httpd -t can be run
6666 via `apachectl configtest'.

6689 *) Make sure the "install" target of the top-level Makefile doesn't break
6690 because of a return code of 1 from an "if" (for instance under braindead
6691 Ultrix the result code of an "if" construct is 1 if the "then" clause
6692 didn't match). [Ralf S. Engelschall]
6694 *) Add an additional "dummy" target to the "$(LIB)" target in generated
6695 modules/xxx/Makefile's to avoid problems with SVR4 Make under "full-DSO"
6696 situation (no libxxx.a built, only mod_xxx.so's) where LIB and OBJS are
6697 empty. [Ralf S. Engelschall, Dean Gaudet, Martin Kraemer]

6725 *) Change "Options None" to "Options FollowSymLinks" in the

6740 Awk like PrintPath but _via different names_.

6777 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
6778 more proper ap_log_error() variants.
6779 [Ralf S. Engelschall]
6781 *) Make sure the argument for the --add-module option to APACI's configure
6782 script is of type [path/to/]mod_xxx.c because all calculations inside
6783 configure and src/Configure depend on this.
6784 [Ralf S. Engelschall] PR#2307
6786 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error

6790 *) Various OS/2 cleanups ["Brian Havard" <brianh@kheldar.apana.org.au>]

6796 *) Have NT properly set the directory for CGI scripts

6798 [W G Stoddard <wgstodda@us.ibm.com>]
6800 *) Propagate environment to CGI scripts correctly in Win32.
6801 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
6803 *) Some symbol renaming:
6804 ap_spawn_child_err became ap_spawn_child
6805 ap_spawn_child_err_buff became ap_bspawn_child
6806 spawn_child was obsoleted and moved to compat.h
6809 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
6810 programs: ap_spawn_child_err() is used and the Win32 case now uses
6811 CreateProcess() instead of a low-level execl() (which caused problems in
6812 the past under Win32).
6813 [Ralf S. Engelschall]
6815 *) A few cosmetics and trivial enhancements to APXS to make the
6816 generated Makefile more user friendly. [Ralf S. Engelschall]
6818 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
6819 was updated to use the normal apache error processing, thereby allowing
6820 proxy errors to be treated by ErrorDocument's as well. For this
6821 purpose, a new module-to-core communication variable "error-notes"
6822 was introduced; the proxy (and possibly other modules) communicates
6823 its error text using this variable. Its content is copied to a new
6824 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
6825 The old proxy special error routine ap_proxy_log_uerror()
6826 was replaced by regular ap_log_error() calls, many messages were made
6828 [Martin Kraemer] PR#494, 1259
6830 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
6833 *) Transform the configure message "You need root privileges for suEXEC"
6834 from a fatal error into a (more friendly) warning because the building
6835 ("make") of Apache we can allow, of course. Root privileges are needed
6836 only for the installation step ("make install"). So make sure the
6837 user is aware of this fact but let him proceed as long as he can.
6838 [Ralf S. Engelschall] PR#2288
6840 *) Renamed three more functions to common ap_ prefix which we missed at the
6841 Big Symbol Renaming because they're #defines and not real C functions:
6842 is_default_port(), default_port(), http_method().
6843 [Ralf S. Engelschall]
6845 *) A zero-length name after a $ in an SSI document should cause
6846 just the $ to be in the expansion. This was broken during the

6849 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some

6856 Changes with Apache 1.3b7
6858 *) Make sure a MIME-type can be forced via a RewriteRule even when no
6859 substitution takes place, for instance via the following rule:
6860 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
6861 requested by users in the past to force a single script without a .cgi
6862 extension and outside any cgi-bin dirs to be executed as a CGI program.
6863 [Ralf S. Engelschall] PR#2254
6865 *) A fix for protocol issues surrounding 400, 408, and
6866 414 responses. [Ed Korthof]

6870 *) Fix discrepancy in proxy_ftp.c which was causing failures when
6871 trying to connect to certain ftpd's, such as anonftpd.
6872 [Rick Ohnemus <rick@ecompcon.com>]
6874 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
6875 logfile instead of fiddling around itself with child spawning stuff.
6876 [Ralf S. Engelschall]
6878 *) Made RefererIgnore case-insensitive.
6880 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
6883 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
6884 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
6887 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
6889 *) Fix support script `dbmmanage': It was unable to handle some sort
6890 of passwords, especially passwords with "0" chars.

6893 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
6894 [Ben Laurie] PR#2238
6896 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
6897 library), so CGI handling has been changed to use Win32 native handles
6898 instead of C file descriptors.
6899 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
6901 *) The proxy cache would store an incorrect content-length in the cached
6902 file copy after a cache update. That resulted in repeated fetching
6903 of the original copy instead of using the cached copy.
6904 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
6906 *) The Makefiles assumed that DSO files are build via $(LD). This
6907 is broken for two reasons: First we never defined at least LD=ld
6908 somewhere to make sure this works (it was silently assumed that most Make
6909 provide a built-in LD definition - ARGL!) and second using the generic LD
6910 variable is not the truth. Instead a special variable named LD_SHLIB is
6911 reasonable because although "ld" is usually the default, the command for
6912 building DSO files can be "libtool" or even "cc" on some systems.
6913 [Ralf S. Engelschall]
6915 *) Replace the AddVersionPlatform directive with ServerTokens which
6916 provides for more control over the format of the Server:
6917 header line. SERVER_SUBVERSION is no longer supported;
6918 all module should use the ap_add_version_component()
6919 API function instead. [Jim Jagielski]
6921 *) Support for the NCR MP/RAS 3.0
6922 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
6924 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
6925 not retrieved in src/Configure and thus was not useable.
6926 [Ralf S. Engelschall]
6928 *) Various Makefile consistency cleanups:
6929 - make OSDIR also automatically be relative to src/ like INCDIR
6930 - SUBDIRS is now generated in src/Makefile only and not in
6931 Makefile.config because it is a local define for this location.
6932 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
6933 any Makefile but make sure that at least the "-K inline" is kept in
6935 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
6936 - updated the dependencies theirself
6937 - removed not existing SHLIB variable from "clean" targets
6938 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
6939 already exists and OBJS_PIC are also just plain objects and have not
6940 directly to do with "shared" things. The only difference is that they
6941 contain PIC. So OBJS_PIC is the more canonical name.
6942 - Updated the Makefile-dependency lines for OBJS_PIC
6943 - Removed the Makefile-dependency line in Configure to avoid double
6945 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
6946 of xxx.lo as GNU libtool does with its PIC objects
6947 - reduce local complexity in modules Makefile.tmpl by moving the last
6948 existing target "depend" to the generation section in Configure, too.
6949 - removed the historical $(SPACER) which was used in the past together
6950 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
6951 is no longer needed.
6952 - force the build and run of the gen_xxx programs under main/ as the
6953 first step before building the objects because it looks cleaner
6954 [Ralf S. Engelschall]
6956 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
6959 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
6962 *) WIN32: Don't force ISAPI headers to finish with \n.
6963 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
6965 *) When opening "configuration" files (like httpd.conf, htaccess
6966 and htpasswd), Apache will not allow them to be non-/dev/null
6967 device files. This closes a DoS hole. At the same time,
6968 we use ap_pfopen to open these files to handle timeouts.
6969 [Jim Jagielski, Martin Kraemer]
6971 *) Apache will now log the reason its httpd children exit if they exit
6972 due to an unexpected signal. (It requires a new porting define,
6973 SYS_SIGLIST, which if defined should point to a list of text
6974 descriptions of the signals available. See PORTING.) [Dean Gaudet]
6976 *) WIN32: chdir() doesn't make sense in a multithreaded environment
6977 like WIN32. Before, Win32 CGI's could have had sporadic failures
6978 if a chdir call from one thread was made between another chdir call
6979 and a spawn in another thread. So, for now don't chdir for CGI scripts
6980 in WIN32. The current CGI "spec" is unclear as to whether it's
6981 necessary. Long-term fix is to either serialize the chdir/spawn combo
6982 or use WIN32 native calls to spawn a process. This temp fix was
6983 necessary to remove this as a showstopper for 1.3's release.
6986 *) Cleanup the suEXEC support in APACI and make it more safe:
6987 1. Add big fat hint in INSTALL about risks and to read the
6988 htdocs/manual/suexec.html document before using the suexec-related
6990 2. Make sure the user has at least provided one --suexec-xxxx option
6991 (specifies suEXEC parameters) in addition to --enable-suexec option.
6992 If only --enable-suexec is given APACI stops with a hint to INSTALL
6993 and htdocs/manual/suexec.html documents.
6994 3. Provide two additional --suexec-xxxx options to make the suEXEC
6995 configuration complete (especially for package maintainers who else
6996 had to patch the source tree) by providing ways to configure minimal
6997 UID/GID and safe PATH, too.
6998 [Ralf S. Engelschall]
7000 *) Cleanup of the `configure --shadow' process:
7001 - make sure the configure script creates its temporary files in the
7002 shadow tree to avoid conflicts with parallel configure runs
7003 - removed unnecessary option "-r" from "rm" call for Makefiles
7004 - make sure the configure scripts creates the shadow-wrapper Makefile
7005 only when no shadow trees already exists
7006 - make sure "make distclean" removes the shadow-wrapper Makefile but only
7007 when no more shadow trees exists
7008 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
7009 as fast (in the past it needed 70sec, now it runs just 38sec)
7010 - make sure CVS does not complain about the created files
7011 Makefille.<gnutriple> and directories src.<gnutriple>
7012 [Ralf S. Engelschall]
7014 *) Added the ap_add_version_component() API routine and the
7015 AddVersionPlatform core directive. The first allows modules to
7016 declare themselves in the Server response header field value,
7017 augmenting the SERVER_SUBVERSION define in the Configuration file
7018 with run-time settings (more useful in a loadable-module environment).
7019 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
7020 into the server version string. [Ken Coar] PR#2056
7022 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
7025 *) Emit the "Accept-Range" header for the default handler.
7026 [Brian Behlendorf] PR#1464
7028 *) Add a note to httpd.conf-dist that apache will on some systems fail
7029 to start when the Group # is set to a negative or large positive value.
7032 *) Make sure the module execution order is correct even when some modules
7033 are loaded under runtime (`LoadModule') via the DSO mechanism:
7034 1. The list of loaded modules is now a dynamically allocated one
7035 and not the original statically list from modules.c
7036 2. The loaded modules are now correctly setup by LoadModule for
7037 later use by the AddModule command.
7038 3. When the DSO mechanism for modules is used APACI's `install'
7039 target now enables all created `LoadModule' lines per default because
7040 this is both already expected by the user _and_ needed to avoid
7041 confusion with the next point and reduces the Makefile.tmpl complexity
7042 4. When the DSO mechanism for modules is used, APACI's `install'
7043 target now additionally makes sure the module list is reconstructed
7044 via a complete `ClearModuleList+AddModule...' entry.
7045 5. The support tool `apxs' now also makes sure an AddModule command
7046 is added in addition to the LoadModule command.
7047 6. The modules.c generation was extended to now contain two
7048 comments to make sure no one is confused by the confusing terminology
7049 of loading/linking (we use load=link+load & link=activate instead of
7050 the obvious load=activate & link=link :-( )
7051 This way now there is no longer a difference under execution time between
7052 statically and dynamically linked modules.
7053 [Ralf S. Engelschall]
7055 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
7056 Big Symbol Renaming. [Ralf S. Engelschall]
7058 *) Add a comment to mod_example.c showing the format of a FLAG command
7061 *) Standardized the time format in mod_status to match that of other
7062 places in the code (e.g. DATE_GMT). PR#1551
7064 *) Fix handling of %Z in timefmt strings for those platforms with no time
7065 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
7068 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
7069 feature compatible with 'UseCanonicalName off' by changing
7070 r->server->server_hostname to ap_get_server_name(). And I changed some
7071 functions which use r->server->port to use ap_get_server_port() instead,
7072 because if there's no Port directive in the config r->server->port is 0.
7075 *) get/set_module_config are trivial enough to be better off inline. Worth
7076 1.5% performance boost. [Dean Gaudet]
7078 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
7079 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
7082 *) [BS2000 security] BS2000 needs an extra authentication to initialize
7083 the task environment to the unprivileged User id. Otherwise CGI scripts
7084 would have a way to gain super user access. [Martin Kraemer]
7086 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
7087 absolute path, only log base name of logging source as is done
7088 in unix. [Martin Kraemer]
7090 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
7091 the encoding type from the Accept-Encoding header (if it's there)
7092 and use it in the response, as that's probably what it'll be expecting.
7093 [Ronald.Tschalaer@psi.ch]
7095 *) Fix to mod_alias: translate_alias_redir is dealing with
7096 a URI, not a filename, so the check for drive letters for win32
7097 and emx is not necessary. [Dean Gaudet]
7099 *) WIN32: Allow .cmd as an executable extension.
7100 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
7102 *) Make Apache header files, and some variables, C++ friendly.
7103 [Michael Anderson's <mka@redes.int.com.mx>]
7105 *) Child processes can now "signal" (by exiting with a status
7106 of APEXIT_CHILDFATAL) the parent process to abort and
7107 shutdown the server if the error in the child process was
7108 fatal enough. [Jim Jagielski]
7110 *) mod_autoindex's find_itme() was sensitive to MIME type case.
7111 [Jim Jagielski] PR#2112
7113 *) Make sure the referer_log and agent_log entries in the default httpd.conf
7114 file are also adjusted for the actual relative installation paths.

7117 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
7119 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
7122 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
7123 Additionally the checks for finding the vendor DSO library were moved
7124 from mod_so.c to Configure because first it needs $PLAT etc. and second
7125 mod_so already uses an abstraction layer and does not fiddle with the
7126 vendor functions itself.
7127 [Jens-Uwe Mager, Ralf S. Engelschall]
7129 *) PORT: Some optimization defines for NetBSD
7130 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
7132 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
7133 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
7135 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
7136 AIX variants should work fine, too. Even AIX 3.x should work). This is
7137 accomplished by using the free DSO emulation code from Jens-Uwe Mager
7138 which we put into a os/unix/os-dso-aix.c file.
7139 [Ralf S. Engelschall]
7141 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
7142 that we should use NET_SIZE_T == int but the include files force size_t.
7143 [Ralf S. Engelschall]
7145 *) Fix two bugs in select() handling in http_main.c.
7148 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
7149 is unset (as it is in situations like timeouts) where it is unclear
7150 whether errno is set or not. [Martin Kraemer]
7152 *) Just having APACI's localstatedir is too general and not enough for most
7153 of the systems. 1.3b6 again required manual APACI patches by package
7154 maintainers from Red Hat and FreeBSD because for their filesystem layout a
7155 little bit more flexibility in configuring the paths is needed. Hence we
7156 provide three additional configure options (--runtimedir, --logfiledir,
7157 --proxycachedir) which now can be used for more granular adjustments if
7158 --localstatedir is not enough to fit the particular needs. As a nice
7159 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
7160 [Ralf S. Engelschall]
7162 *) Make the install root for "make install" in APACI's Makefile overrideable
7163 by package authors. This way we are even more friendly to package
7164 maintainers (especially Debian and Red Hat) who build for the real prefix
7165 via "configure --prefix=/<real>" but use a different local prefix via
7166 "make root=/tmp/apache install" for rolling the package without bristling
7167 the target location on their system.
7168 [Ralf S. Engelschall]
7170 *) Workaround sed limitations in APACI's configure script by now
7171 substituting in chunks of 50 commands (because for instance HPUX's vendor
7172 sed has a limit of max. 98 commands)
7173 [Ralf S. Engelschall] PR#2136
7175 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
7176 [Ralf S. Engelschall] PR#2140
7178 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
7179 RENAMING process because they are defined as pre-processor macros instead
7180 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
7181 [Ralf S. Engelschall]
7183 *) Workaround braindead AWK's when generating ap_config.h: The split() and
7184 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
7185 [Ralf S. Engelschall] PR#2139
7187 *) Various bugfixes and cleanups for the APACI configure script:
7188 o fix IFS handling for _nested_ situation
7189 o fix Perl interpreter search: take first one found instead of last one
7190 o fix DSO consistency check
7191 o print error messages to stderr instead of stdout
7192 o add install-quiet for --shadow situation to Makefile stub
7193 o reduce complexity by avoiding sed-hacks for rule and module list loops
7194 [Ralf S. Engelschall]
7196 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
7198 *) Make sure the input field separator (IFS) shell variable is explicitly
7199 initialized correctly before _every_ `for' loop and also restored after
7200 the loops. [Ralf S. Engelschall]
7202 *) Make sure that "make install" doesn't overwrite the `mime.types' and
7203 `magic' files from an existing Apache installation. Because people often
7204 customize these for own MIME and content types.
7205 [Ralf S. Engelschall]
7207 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
7208 [Peter Galbavy, Ralf S. Engelschall] PR#2109
7210 *) Fix the path to the ScoreBoardFile in the install-config target, too.
7211 [Ralf S. Engelschall] PR#2105
7213 *) Let "configure" clear out the users parameters (provided as shell
7214 variables) to avoid side-effects in "src/Configure" when the user
7215 exported them (which is not needed, but some users do it).
7216 [Ralf S. Engelschall] PR#2101
7218 *) Provide backward compatibility from some old src/Configuration.tmpl
7219 parameter names to the canonical Autoconf-style shell variable names. For
7220 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
7221 but a hint message is displayed. [Ralf S. Engelschall]
7223 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
7224 CGI scripts from an existing Apache installation.
7225 [Ralf S. Engelschall, Jim Jagielski] PR#2084
7227 *) Make `configure --compat' more "compatible" by first
7228 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
7229 second by making sure the "avoid-bristling-suffix" /apache is not
7230 appended to sysconfdir, datadir, localstatedir and includedir when
7231 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
7233 *) NeXT required strdup() in support/logresolve.c

7239 *) Fix the path to the MimeMagicFile in the install-config target, too.
7240 [Ralf S. Engelschall] PR#2089
7242 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
7244 *) If you start apache with the -S command line option it will dump
7245 out the parsed vhost settings. This is useful for folks trying
7246 to figure out what is wrong with their vhost configuration.
7247 (Other dumps may be added in the future.) [Dean Gaudet]
7249 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
7250 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
7253 *) Because /usr/local/apache is the default prefix the ``configure
7254 --compat'' option no longer has to set prefix, again. This way the
7255 --compat option honors a leading --prefix option. [Lars Eilebrecht]
7257 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
7258 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
7259 to avoid "discard const" warnings. [Ralf S. Engelschall]
7261 *) If a specific handler is set for a file yet the request still
7262 ends up being handled by the default handler, log an error
7263 message before handling it. This catches things such as trying
7264 to use SSIs without mod_include enabled. [Marc Slemko]
7266 *) Fix error logging for the startup case where ap_log_error() still uses
7267 stderr as the target. Now the default log level is honored here, too.
7268 [Ralf S. Engelschall]
7270 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
7271 long" errors when generating the MODULES entry for src/Makefile
7272 [Ben Hyde, Ralf S. Engelschall]
7274 *) Make sure src/Configure doesn't complain about the old directory
7275 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
7277 Changes with Apache 1.3b6
7279 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
7281 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
7282 interface via the similar but proprietary HP/UX shl_xxx-style system
7283 calls. [Ralf S. Engelschall]
7285 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
7286 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
7287 Make. [Ralf S. Engelschall]
7289 *) ++++ THE BIG SYMBOL RENAMING ++++
7290 To avoid symbol clashes with third-party code compiled into the server,
7291 we globally applied the prefix "ap_" to the following classes of
7293 - Apache provided general functions (e.g., ap_cpystrn)
7294 - Public API functions (e.g., palloc, bgets)
7295 - Private functions which we can't make static (because of
7296 cross-object usage) but should be (e.g., new_connection)
7297 For backward source compatibility a new header file named compat.h was
7298 created which provides defines for the old symbol names and can be used
7299 by third-party module authors.
7302 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
7303 problem under SVR4 is that there is no command flag to force the linker
7304 to export the global symbols of the httpd executable therewith they are
7305 available to the DSO's. Instead of problematic hacks like creating a
7306 dummy.so file (containing dummy references to all global symbols) the
7307 httpd binary is linked against, we use a clean trick stolen from Perl 5:
7308 Placing the Apache core code itself into a DSO library named libhttpd.so.
7309 This way the global symbols _HAVE_ to be exported and thus are available
7310 to any manually loaded DSO's under runtime. To reduce the impact to the
7311 user to null we go even further and create a stub httpd executable which
7312 automatically keeps track of the DSO library loading itself and thus
7313 hides the complete mechanism from the user. Although the generation of
7314 this DSO library is automatically triggered for platforms which
7315 essentially need it (mostly all SVR4-derivates) it can be also enabled
7316 manually via the Rule SHARED_CORE. This can be interesting in the future
7317 where we perhaps exploit this libhttpd.so mechanism for providing nifty
7318 features like graceful upgrades, or whatever.
7319 [Ralf S. Engelschall, Martin Kraemer]
7321 *) Build the libraries before building the rest of the tools. [Ben Hyde]
7323 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
7324 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
7325 conventions while "clean" removes only stuff created by "all" targets,
7326 "distclean" additionally removes the stuff from the configuration
7327 process. This way "make distclean" (hence the name) provides a fresh
7328 source tree as it was for distribution.
7329 [Ralf S. Engelschall]
7331 *) Allow top-level (APACI) Makefile to break on build errors
7332 the same way the src/ subtree Makefiles breaks on them by replacing the
7333 initial APACI sed-subdir-display-kludge with a more clean
7334 variable-passing-solution: variable SDP can optionally hold the subdir
7335 prefix which is consistently used for displaying the subdir movement.
7336 This way even the top-level Makefile can stop correctly on errors as the
7337 user expects. [Ralf S. Engelschall]
7339 *) Fixed ordering of argument checks for RewriteBase directive.
7340 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
7342 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
7343 indicating that a module is being compiled for dynamic loading. Also
7344 remove #define IS_MODULE from modules and add SHARED_MODULE define
7345 to the mak/dsp files. [Alexei Kosut]
7347 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
7348 since we are now logging APLOG_WARNING by default. [Roy Fielding]
7350 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
7352 *) Add documentation file and src/Configuration.tmpl entry for the
7353 experimental mod_mmap_static module. Because although it is and marked as
7354 an experimental one it is distributed and thus should be documented and
7355 prepared for configuration the same way as all others modules.
7356 [Ralf S. Engelschall]
7358 *) Add query (-q) option to apxs support tool to be able to manually query
7359 specific settings from apxs. This is needed for instance when you
7360 manually want to access Apache's header files and you need to assemble
7361 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
7362 [Ralf S. Engelschall]
7364 *) Now src/Configure uses a fallback strategy for the shared object support
7365 on platforms where no explicit information is available: If a Perl
7366 installation exists we ask it about its shared object support and if it's
7367 the dlopen-style one we shamelessly guess the compiler and linker flags
7368 for creating shared objects from Perls knowledge. Of course, the user is
7369 warning about what we are doing and informed that he should send us
7370 the guessed flags when they work. [Ralf S. Engelschall]
7372 *) Provide APACI --without-support option to be able to disable the build
7373 and installation of the support tools from the src/support/ area.
7374 Although its useful to have these installed per default we should provide
7375 a way to compile and install without them for backward-compatibility.
7376 [Ralf S. Engelschall]
7378 *) Add of the new APache eXtenSion (apxs) support tool for building and
7379 installing modules into an _already installed_ Apache package through the
7380 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
7381 this approach actually doesn't need the Apache source tree. The
7382 (APACI-installed) server package is enough, because this now includes the
7383 Apache C header files (PREFIX/include) and the new APXS tool
7384 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
7385 module authors to build their Apache modules _OUTSIDE_ the Apache source
7386 tree while avoiding them to fiddle around with the totally platform
7387 dependend way of compiling DSO files. The tool supports all ranges of
7388 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
7389 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
7390 on-the-fly generate a minimalistic Makefile and sample module for the
7391 first step to provide both a quick success event and to demonstrate the
7392 APXS mechanism to module authors. [Ralf S. Engelschall]
7394 *) Fix core dumps in use of CONNECT in proxy.
7395 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
7397 *) Modify the log directives in httpd.conf-dist files to use CustomLog
7398 so that users have examples of how CustomLog can be used.
7401 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
7402 the Apache distribution tree. Until Apache 1.3 there was no real
7403 out-of-the-box batch-capable build and installation procedure for the
7404 complete Apache package. This is now provided by a top-level "configure"
7405 script and a corresponding top-level "Makefile.tmpl" file. The goal is
7406 to provide a GNU Autoconf-style frontend which is capable to both drive
7407 the old src/Configure stuff in batch and additionally installs the
7408 package with a GNU-conforming directory layout. Any options from the old
7409 configuration scheme are available plus a lot of new options for flexibly
7410 customizing Apache. [Ralf S. Engelschall]
7412 *) The floating point ap_snprintf code wasn't threadsafe.
7413 Had to remove the HAVE_CVT macro in order to do threadsafe
7414 calling of the ?cvt() floating point routines. [Dean Gaudet]
7416 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
7418 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
7419 [Jim Jagielski] PR#1901
7421 *) BUG: Configure was using TCC and CC inconsistently. Make sure
7422 Configure knows which CC we are using. [Jim Jagielski]
7424 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
7425 was defined in a parent directory. [Lars Eilebrecht]
7427 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
7428 a generic printf-style routine that can call arbitrary output
7429 routines. Use this to replace http_bprintf.c. Add new routines
7430 psprintf(), pvsprintf() which allocate the exact amount of memory
7431 required for a string from a pool. Use psprintf() to clean up
7432 various bits of code which used ap_snprintf()/pstrdup().
7435 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
7436 ap_snprintf() has different semantics and formatting codes than
7437 snprintf(). [Dean Gaudet]
7439 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
7440 is necessary on at least Solaris where the /etc/rc?.d scripts
7441 are run with these signals ignored, and "SIG_IGN" settings are
7442 maintained across exec().
7443 [Rein Tollevik <reint@sys.sol.no>] PR#2009

7449 *) Fix the proxy pass-through feature of mod_rewrite for the case of
7450 existing QUERY_STRING now that mod_proxy was recently changed because of
7451 the new URL parsing stuff. [Ralf S. Engelschall]
7453 *) A few changes to scoreboard definitions which helps gcc generate
7454 better code. [Dean Gaudet]
7456 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
7457 be a signed bitfield. So mark a few bitfields as signed to
7458 ensure correct code. [Dean Gaudet]

7461 was a problem and it wasn't taking effect. [Dean Gaudet]
7463 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
7466 *) After a SIGHUP the listening sockets in the parent weren't
7467 properly marked for closure on fork().
7468 [Jürgen Keil <jk@tools.de>] PR#2000
7470 *) Allow %2F in two situations: 1) it is in the query part of the URI,
7471 therefore not exposed to %2F -> '/' translations and 2) the request
7472 is a proxy request, so we're not dealing with a local resource anyway.
7473 Without this, the proxy would fail to work for any URL's with
7474 %2f in them (occurs quite often in
7475 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
7477 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
7479 *) Make the shared object compilation command more portable by avoiding
7480 the direct combination of `-c' & `-o' which is not honored by some
7481 compilers like UnixWare's cc. [Ralf S. Engelschall]
7483 *) WIN32: the proxy was creating filenames missing the last four
7484 characters. While this normally doesn't stop anything from
7485 working, it can result in extra collisions.
7486 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
7488 *) Now mod_proxy uses the response string (in addition to the response status
7489 code) from the already used FTP SIZE command to setup the Content-Length
7490 header if available. [Ralf S. Engelschall] PR#1183
7492 *) Reanimated the (still undocumented) proxy receive buffer size directive:
7493 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
7494 name was really too generic, added documentation for this directive to
7495 the mod_proxy.html and corrected the hyperlink to it in the
7496 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
7498 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
7499 faster [Martin Kraemer]
7501 *) Make Configure die when you give it an unknown command switch.
7504 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
7505 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
7506 and per default compiled support programs have manual pages - just to
7507 document our stuff a little bit more and to be able to do really
7508 Unix-like installations ;-) [Ralf S. Engelschall]
7510 *) Major cleanups to the Configure script to make it and its generated
7511 Makefiles again readable and maintainable: add SRCDIR option, removed
7512 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
7513 generated sections, consequently added Makefile headers with inheritance
7514 information, added subdir movement messages for easier following where
7515 the build process currently stays (more verbose then standard Make, less
7516 verbose than GNU make), same style to comments in the Configure script,
7517 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
7519 *) Add the new ApacheBench program "ab" to src/support/: This is derived
7520 from the ZeusBench benchmarking program and can be used to determine the
7521 response performance of an Apache installation. This version is
7522 officially licensed with Zeus Technology, Ltd. See the license agreement
7523 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
7524 [Ralf S. Engelschall]
7526 *) API: Various core functions that are definately not part of the API
7527 have been made static, and a few have been marked API_EXPORT. Still
7528 more have been marked CORE_EXPORT and are not intended for general
7529 use by modules. [Doug MacEachern, Dean Gaudet]
7531 *) mod_proxy was not clearing the Proxy-Connection header from
7532 requests; now it does. This did not violate any spec, however
7533 causes poor interactions when you are talking to remote proxies.
7534 [Marc Slemko] PR#1741
7536 *) Various cleanups to the command line interface and manual pages.
7537 [Ralf S. Engelschall]
7539 *) cfg_getline() was not properly handling lines that did not end
7540 with a line termination character. [Marc Slemko] PR#1869, 1909
7542 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
7544 *) Clean up some undocumented behavior of mod_setenvif related to
7545 "merging" two SetEnvIf directives when they match the same header
7546 and regex. Document that mod_setenvif will perform comparisons in
7547 the order they appear in the config file. Optimize mod_setenvif by
7548 doing more work at config time rather than at runtime.
7551 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
7552 to allow for modules to overrule them and to reduce redefinition
7553 warnings [Jim Jagielski]
7555 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
7558 *) Making the hard-coded cross-module function call mime_find_ct() (from
7559 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
7560 checking is really called even for proxy requests except for URLs with
7561 HTTP schemes (because there we can optimize by not running the type
7562 checking hooks due to the fact that the proxy gets the MIME Content-type
7563 from the remote host later). This change cleans up mod_mime by removing
7564 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
7565 especially unbundles mod_proxy and mod_mime. This way they both now can
7566 be compiled as shared objects and are no longer tied together.
7567 [Ralf S. Engelschall]
7569 *) util.c cleanup and speedup. [Dean Gaudet]
7571 *) API: Clarification, pstrndup() will always copy n bytes of the source
7572 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
7574 *) Mark module command_rec and handler_rec structures const so that they
7575 end up in the read-only data section (and are friendlier to systems
7576 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
7578 *) Add check to the "Port" directive to make sure the specified
7579 port is in the appropriate range. [Ben Hyde]
7581 *) Performance improvements to invoke_handler().
7582 [Dmitry Khrustalev <dima@bog.msu.su>]
7584 *) Added support for building shared objects even for library-style modules
7585 (which are built from more than one object file). This now provides the
7586 ability to build mod_proxy as a shared object module. Additionally
7587 modules like mod_example are now also supported for shared object
7588 building because the generated Makefiles now no longer assume there is at
7589 least one statically linked module. [Ralf S. Engelschall]
7591 *) API: Clarify usage of content_type, handler, content_encoding,
7592 content_language and content_languages fields in request_rec. They
7593 must always be lowercased; and the strings pointed to shouldn't
7594 be modified (you must copy them to modify them). Fix a few bugs
7595 related to this. [Dean Gaudet]
7597 *) API: Clarification: except for RAW_ARGS, all command handlers can
7598 treat the char * parameters as permanent, and modifiable. There
7599 is no need to pstrdup() them. Clean up some needless pstrdup().
7602 *) Now mod_so keeps track of which module shared objects with which names
7603 are loaded and thus avoids multiple loading and unloading and irritating
7604 error_log messages. [Ralf S. Engelschall]
7606 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
7607 environment variable in the apache core. But that tweaking interferes
7608 with mod_setenv. So don't tweak if the user has specified an explicit
7609 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
7611 *) rputs() did not calculate r->sent_bodyct properly.
7612 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
7614 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
7615 name, or left unset if this value is unavailable. Apache was setting
7616 it to the IP address when unavailable.
7617 [Tony Finch <fanf@demon.net>] PR#1925
7619 *) Various improvements to the configuration and build support for compiling
7620 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
7621 OSF1 support with GCC and vendor compilers was added. This way shared
7622 object support is now provided out-of-the-box for FreeBSD, Linux,
7623 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
7624 [Ralf S. Engelschall]
7626 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
7627 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
7628 and USE_OS2_SCOREBOARD. [Dean Gaudet]
7630 *) Fix one more special locking problem for RewriteMap programs in
7631 mod_rewrite: According to the documentation of flock(), "Locks are on
7632 files, not file descriptors. That is, file descriptors duplicated
7633 through dup(2) or fork(2) do not result in multiple instances of a lock,
7634 but rather multiple references to a single lock. If a process holding a
7635 lock on a file forks and the child explicitly unlocks the file, the
7636 parent will lose its lock.". To overcome this we have to make sure the
7637 RewriteLock file is opened _AFTER_ the childs were spawned which is now
7638 the case by opening it in the child_init instead of the module_init API
7639 hook. [Ralf S. Engelschall] PR#1029
7641 *) Change to Location and LocationMatch semantics. LocationMatch no
7642 longer lets a single slash match multiple adjacent slashes in the
7643 URL. This change is for consistency with RewriteRule and
7644 AliasMatch. Multiple slashes have meaning in URLs that they do
7645 not have in (some) filesystems. Location on the other hand can
7646 be considered a shorthand for a more complicated regex, and it
7647 does match multiple slashes with a single slash -- which is
7648 also consistent with the Alias directive.
7649 [Dean Gaudet] related PR#1440
7651 *) Fix bug with mod_mime_magic causing certain files, including files
7652 of length 0, to result in no response from the server.
7655 *) The Configure script now generates src/include/ap_config.h which
7656 contains the set of defines used when Apache is compiled on a platform.
7657 This file can then be included by external modules before including
7658 any Apache header files in case they are being built separately from
7659 Apache. Along with this change, a couple of minor changes were
7660 made to make Apache's #defines coexist peacefully with any autoconf
7661 defines an external module might have. [Rasmus Lerdorf]
7663 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
7664 but without any RewriteXXXXX directives. Here mod_rewrite is given no
7665 chance by the API to initialize its per-server configuration and thus
7666 receives the wrong one from the main server. This is now avoided by
7667 remembering the server together with the config structure while
7668 configuring and later assuming there is no config when we see a
7669 difference between the remembered server and the one calling us.
7670 [Ralf S. Engelschall] PR#1790
7672 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
7673 is automatically disabled under configure time when the dbm_xxx functions
7674 are not available. Second, two heavy source code errors in the DBM
7675 support code were fixed. This makes DBM RewriteMap's usable again after
7676 a long time of brokenness. [Ralf S. Engelschall] PR#1696
7678 *) Now all configuration files support Unix-style line-continuation via
7679 the trailing backslash ("\") character. This enables us to write down
7680 complex or just very long directives in a more readable way. The
7681 backslash character has to be really the last character before the
7682 newline and it has not been prefixed by another (escaping) backslash.
7683 [Ralf S. Engelschall]
7685 *) When using ProxyPass the ?querystring was not passed correctly.
7686 [Joel Truher <truher@wired.com>]
7688 *) To deal with modules being compiled and [dynamically] linked
7689 at a different time from the core, the SERVER_VERSION and
7690 SERVER_BUILT symbols have been abstracted through the new
7691 API routines apapi_get_server_version() and apapi_get_server_built().
7694 *) WIN32: Preserve trailing slash in canonical path (and hence
7695 in PATH_INFO). [Paul Sutton, Ben Laurie]
7697 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
7698 depending on the rev of Solaris and what mixture of modules
7699 are in use. So it has been disabled, and Solaris is back to
7700 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
7701 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
7702 up static content only servers. Or it may fail unpredictably.
7703 [Dean Gaudet] PR#1779, 1854, 1904
7705 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
7708 *) API: Rewrite of absoluteURI handling, and in particular how
7709 absoluteURIs match vhosts. Unless a request is a proxy request, a
7710 "http://host" url is treated as if a similar "Host:" header had been
7711 supplied. This change was made to support future HTTP/1.x protocols
7712 which may require clients to send absoluteURIs for all requests.
7714 In order to achieve this change subtle changes were made to the API. In a
7715 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
7716 that the unmodified uri can be retrieved easily. r->proxyreq is not set
7717 by the core, modules must set it during the post_read_request or
7718 translate_names phase.
7720 Plus changes to the virtualhost test suite for absoluteURI testing.
7722 This fixes several bugs with the proxy proxying requests to vhosts
7723 managed by the same httpd.
7726 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
7727 code from mod_rewrite. The vhost matching is now performed by a
7728 globally available function matches_request_vhost(). [Dean Gaudet]
7730 *) Reduce memory usage, and speed up ServerAlias support. As a
7731 side-effect users can list multiple ServerAlias directives
7732 and they're all considered.

7739 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
7741 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
7742 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
7744 *) API: A new source module main/util_uri.c; It contains a routine
7745 parse_uri_components() and friends which breaks a URI into its component
7746 parts. These parts are stored in a uri_components structure called
7747 parsed_uri within each request_rec, and are available to all modules.
7748 Additionally, an unparse routine is supplied which re-assembles the URI
7749 components back to an URI, optionally hiding the username:password@ part
7750 from ftp proxy requests, and other useful routines. Within the structure,
7751 you find on a ready-for-use basis:
7752 scheme; /* scheme ("http"/"ftp"/...) */
7753 hostinfo; /* combined [user[:password]@]host[:port] */
7754 user; /* user name, as in http://user:passwd@host:port/ */
7755 password; /* password, as in http://user:passwd@host:port/ */
7756 hostname; /* hostname from URI (or from Host: header) */
7757 port_str; /* port string (integer representation is in "port") */
7758 path; /* the request path (or "/" if only scheme://host was given) */
7759 query; /* Everything after a '?' in the path, if present */
7760 fragment; /* Trailing "#fragment" string, if present */
7761 This is meant to serve as the platform for *BIG* savings in
7762 code complexity for the proxy module (and maybe the vhost logic).
7765 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
7766 ${map:key}) available for all location where a string is created in
7767 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
7768 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
7769 possible expansions are consequently usable at all string creation
7770 locations. [Ralf S. Engelschall]
7772 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
7773 and not 1) and the per-virtual-server merging of directives. Now all
7774 directives except `RewriteEngine' and `RewriteOption' are either
7775 completely overridden (default) or completely inherited (when
7776 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
7778 *) Fix `RewriteMap' program lookup in situations where such maps are
7779 defined but disabled (`RewriteEngine off') in per-server context.
7780 [Ralf S. Engelschall] PR#1431
7782 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
7783 server to bind to port 0 rather than 80. [Dean Gaudet]
7785 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
7786 (like SunOS and FreeBSD) which don't accept the locking of pipes
7787 directly. A new directive RewriteLock is introduced which can be used to
7788 setup a separate locking file which then is used for synchronization.

7792 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently

7803 *) The mod_setenvif BrowserMatch backwards compatibility command did not
7804 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
7806 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
7807 type but with a special post-processing for the looked-up value: It
7808 parses it into alternatives according to `|' chars and then only one
7809 particular alternative is chosen randomly (this is an essential
7810 functionality needed for balancing between backend-servers when using
7811 Apache as a Reverse Proxy. The looked up value here is a list of
7812 servers). Second, `int' with the built-in maps named `tolower' and
7813 `toupper' which can be used to map URL parts to a fixed case (this is an
7814 essential feature to fix the case of server names when doing mass
7815 virtual-hosting with the help of mod_rewrite instead of using
7816 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
7817 Jay Soffian <jay@cimedia.com>] PR#1631
7819 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
7820 This directive lets Apache adjust the URL in Location-headers on HTTP
7821 redirect responses sent by the remote server. This way the virtually
7822 mapped area is no longer left on redirects and thus by-passed which is
7823 especially essential when running Apache as a reverse proxy.

7934 *) MiNT port update. [Jan Paul Schmidt]
7936 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
7937 equivalent, similarly for x-compress and compress. Apache
7938 now ignores a leading x- when comparing encodings. It also
7939 preserves the encoding the client requests (for example if
7940 it requests x-gzip, then Apache will respond with x-gzip
7941 in the Content-Encoding header).

7971 *) Yet another rearrangement of the source tree.. now all the common
7972 header files are in the src/include directory. The -Imain -Iap
7973 references in Makefiles have been changed to the simpler -Iinclude
7974 instead. In addition to simplifying the build a little bit, this
7975 also makes it clear when a module is referencing something in a
7976 other than kosher manner (e.g., the proxy including mod_mime.h).
7977 Module-private header files (the proxy, mod_mime, the regex library,
7978 and mod_rewrite) have not been moved to src/include; nor have
7979 the OS-abstraction files. [Ken Coar]

7991 server setting inside vhosts (only an issue when you have no
7992 <Directory> or other section containing an Options that affects

8008 *) mod_unique_id was erroneously generating a second unique id when
8009 an internal redirect occured. Such redirects occur, for example,
8010 when processing a DirectoryIndex match. [Dean Gaudet]
8012 *) API: table_add, table_merge, and table_set include implicit pstrdup()
8013 of the key and value. But in many cases this is not required
8014 because the key/value is a constant, or the value has been built
8015 by pstrcat() or other similar means. New routines table_addn,
8016 table_mergen, and table_setn have been added to the API, these
8017 routines do not pstrdup() their arguments. The core code and
8018 standard modules were changed to take advantage of these routines.
8019 The resulting server is up to 20% faster in some situations.
8021 Note that it is easy to get code subtly wrong if you pass a key/value
8022 which is in a pool other than the pool of the table. The only
8023 safe thing to do is to pass key/values which are in the pool of
8024 the table, or in one of the ancestors of the pool of the table.
8025 i.e. if the table is part of a subrequest, a value from the main
8026 request's pool is OK since the subrequest pool is a sub_pool of the
8027 main request's pool (and therefore has a lifespan at most as long as
8028 the main pool). There is debugging code which can detect improper
8029 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

8032 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
8033 which don't exist on disk more gracefully; handles vhosts properly.
8034 Update documentation to reflect the code -- if there's no
8035 MimeMagicFile directive then the module is not enabled.
8038 *) PORT: Some older *nix dialects cannot automatically start scripts
8039 which begin with a #! interpreter line (the shell starts the scripts
8040 appropriately on these platforms). Apache now supports starting of
8041 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

8047 some standard modules got this wrong. By changing the definition
8048 to "typedef struct table table" module authors will receive compile
8049 time warnings that they're doing the wrong thing. This change
8050 facilitates future changes with more sophisticated table

8067 OS has that method of shared memory; the type to use for
8068 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
8069 and USE_SHMGET_SCOREBOARD). This allows outside modules to
8070 determine if shared memory is available and allows Apache
8071 to determine the best method to use for the scoreboard.
8074 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
8075 as do various earlier versions. It should be safe on all versions.
8076 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
8077 the slack code. A few other cleanups for Unixware.

8080 *) PORT: A/UX can handle single-listen accepts without mutex
8081 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
8083 *) When die() happens we need to eat any request body if one exists.
8084 Otherwise we can't continue with a keepalive session. This shows up

8086 authenticated. [Roy Fielding] PR#1399

8099 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
8100 The choice of flock vs. fcntl was made based on timings which showed that
8101 even on non-NFS, non-exported filesystems fcntl() was an order of
8102 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
8103 that single socket users will see no difference. [Dean Gaudet] PR#467

8126 purposes caused some compilers heartburn without adding any
8127 significant value, so they've been removed. [Ken Coar]
8129 *) The src/main/*.h header files have had #ifndef wrappers added to
8130 insulate them against duplicate calls if they get included through
8131 multiple paths (e.g., in .c files as well as other .h files).
8134 *) The libap routines now have a header file for their prototypes,
8135 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
8137 *) mod_autoindex with a plaintext header file would emit the <PRE>

8142 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8143 only an issue on systems without a MAXDNAME define or where
8144 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8146 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which

8161 [Ronald.Tschalaer@psi.ch] PR#1666
8163 *) For maximum portability, the environment passed to CGIs should
8164 only contain variables whose names match the regex
8165 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
8166 underscores over any character outside the regex. This
8167 affects HTTP_* variables, in a way that should be backward
8168 compatible for all the standard headers; and affects variables
8169 set with SetEnv/BrowserMatch and similar directives.

8212 (connections are not dropped). Code can handle graceful restarts
8213 (but there is as yet no way to signal this to Apache). Various
8214 other cleanups. [Paul Sutton]
8216 *) The aplog_error changes specific to 1.3 introduced a buffer
8217 overrun in the (now legacy) log_printf function. Fixed.
8220 *) mod_digest didn't properly deal with proxy authentication. It
8221 also lacked a case-insensitive comparision of the "Digest"

8258 *) The bputc() macro was not properly integrated with the chunking
8259 code; in many cases modules using bputc() could cause completely
8260 bogus chunked output. (Typically this will show up as problems
8261 with Internet Explorer 4.0 reading a page, but other browsers
8262 having no problem.) [Dean Gaudet]
8264 *) Create LARGE_WRITE_THRESHOLD define which determines how many
8265 bytes have to be supplied to bwrite() before it will consider
8266 doing a writev() to assemble multiple buffers in one system
8267 call. This is critical for modules such as mod_include,
8268 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
8269 strings in some cases. The result would be extra effort
8270 setting up writev(), and in many cases extra effort building
8271 chunks. The default is 31, it can be overriden at compile

8393 which are allocated in each child, for cleanup in each child.
8394 A new pool was created which is passed to the module child_init
8395 and child_exit functions; modules are free to register per-child
8396 cleanups there. This fixes a bug with reliable piped logs.
8399 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom

8406 read the file. [Ben Hyde <bhyde@gensym.com>]
8408 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
8409 Now the rewriting engine (the heart of mod_rewrite) is organized more
8410 straight-forward, first time well documented and reduced to the really
8411 essential parts. All redundant cases were stripped off and processing now
8412 is the same for both per-server and per-directory context with only a
8413 minimum difference (the prefix stripping in per-dir context). As a
8414 side-effect some subtle restrictions and two recently discovered problems
8415 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
8416 context and restrictions on the substitution URL on redirects.
8417 Additionally some minor source cleanups were done.

8582 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()

8599 be used for whatever reason is appropriate (i.e. format() warnings
8600 for printf style functions). Both are enabled only with
8601 gcc >= 2.7.x (so that we have fewer support issues with older
8602 versions). [Dean Gaudet]
8604 *) Fix support for Proxy Authentication (we were testing the response
8605 status too early). [Marc Slemko]
8607 *) CoreDumpDirectory directive directs where the core file is
8608 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
8609 received. [Marc Slemko, Dean Gaudet]
8611 *) PORT: Support for Atari MINT.
8612 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
8614 *) When booting, apache will now detach itself from stdin, stdout,
8615 and stderr. stderr will not be detached until after the config
8616 files have been read so you will be able to see initial error
8617 messages. After that all errors are logged in the error_log.
8618 This makes it more convenient to start apache via rsh, ssh,
8619 or crontabs. [Dean Gaudet] PR#523
8621 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8622 Also removed the auto-generated link to www.apache.org that was the
8623 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8625 *) send_fb would not detect aborted connections in some situations.
8628 *) mod_include would use uninitialized data when parsing certain
8629 expressions involving && and ||. [Brian Slesinsky] PR#1139
8631 *) mod_imap should only handle GET methods. [Jay Bloodworth]
8633 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8635 *) mod_autoindex improperly counted &escapes; as more than one
8636 character in the description. It also improperly truncated
8637 descriptions that were exactly the maximum length.
8640 *) RedirectMatch was not properly escaping the result (PR#1155). Also
8641 "RedirectMatch /advertiser/(.*) $1" is now permitted.
8644 *) mod_include now uses symbolic names to check for request success
8645 and return HTTP errors, and correctly handles all types of
8646 redirections (previously it only did temporary redirect correctly).
8647 [Ken Coar, Roy Fielding]
8649 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8650 r->filename. Since those two are meant to be in sync with each other
8651 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
8653 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
8654 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
8656 *) Inetd mode (which is buggy) uses timeouts without having setup the
8657 jmpbuffer. [Dean Gaudet] PR#1064
8659 *) Work around problem under Linux where a child will start looping
8660 reporting a select error over and over.
8661 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
8663 *) Fixed error in proxy_util.c when looping through multiple host IP
8664 addresses. [Lars Eilebrecht] PR#974
8666 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
8667 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
8668 bytes before writing, but it will never split a log entry across a
8669 buffer boundary. [Dean Gaudet]
8671 *) API: the short_score record has been split into two pieces, one which
8672 the parent writes on, and one which the child writes on. As part of
8673 this change the get_scoreboard_info() function was removed, and
8674 scoreboard_image was exported. This change fixes a race condition
8675 in file based scoreboard systems, and speeds up changes involving the
8676 scoreboard in earlier 1.3 development. [Dean Gaudet]
8678 *) API: New register_other_child() API (see http_main.h) which allows
8679 modules to register children with the parent for maintenance. It
8680 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
8682 *) API: New piped_log API (see http_log.h) which implements piped logs,
8683 and will use register_other_child to implement reliable piped logs
8684 when it is available. The reliable piped logs part can be disabled
8685 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
8686 logs is only available on Unix. [Dean Gaudet]
8688 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
8689 meets_conditions(). This allows conditional HTTP selection to be
8690 handled separately from the storing of the header fields, and provides
8691 the ability for CGIs to set their own ETags for conditional checking.
8692 [Ken Coar, Roy Fielding] PR#895
8694 *) Changes to mod_log_config to allow naming of format strings.
8695 Format nicknames are defined with "LogFormat fmt nickname", and can
8696 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
8699 *) New module, "mod_speling", which can help find files even when
8700 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
8702 *) API: New function child_terminate() triggers the child process to
8703 exit, while allowing the child finish what it needs to for the
8704 current request first.
8705 [Doug MacEachern, Alexei Kosut]
8707 *) Windows now defaults to using full status reports with mod_status.
8708 [Alexei Kosut] PR #1094
8710 *) *Really* disable all mod_rewrite operations if the engine is off.
8711 Some things (like RewriteMaps) were checked/performed even if they
8712 weren't supposed to be. [Ken Coar] PR #991
8714 *) Implement a new timer scheme which eliminates the need to call alarm() all
8715 the time. Instead a counter in the scoreboard for each child is used to
8716 show when the child has made forward progress. The parent samples this
8717 counter every scoreboard maintenance cycle, and issues SIGALRM if no
8718 progress has been made in the timeout period. This reduces the static
8719 request best-case syscall count to 22 from 29. This scheme is only
8720 used by systems with memory-based scoreboards. [Dean Gaudet]
8722 *) The proxy now properly handles CONNECT requests which are sent
8723 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
8725 *) A script called apachectl has been added to the support
8726 directory. This script allows you to do things such as
8727 "apachectl start" and "apachectl restart" from the command
8730 *) Modules and core routines are now put into libraries, which
8731 simplifies the link line tremendously (among other advantages).
8734 *) Some of the MD5 names defined in Apache have been renamed to have
8735 an `ap_' prefix to avoid conflicts with routines supplied by
8736 external libraries. [Ken Coar]
8738 *) Removal of mod_auth_msql.c from the distribution. There are many
8739 other options for databases today. Rather than offer one option,
8740 offer none at this time. mod_auth_msql and other SQL database
8741 authentication modules can be found at the Apache Module Registry.
8742 http://modules.apache.org/ It would be nice to offer a generic
8743 mod_auth_sql option in the near future.
8745 *) PORT: BeOS support added [Alexei Kosut]
8747 *) Configure no longer accepts the -make option, since it creates
8748 Makefile on the fly based on Makefile.tmpl and Configuration.
8750 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
8751 of forcibly killing off all its processes and exiting without
8752 cleaning up. [Alexei Kosut]
8754 *) API: A new field in the request_rec, r->mtime, has been added to
8755 avoid gratuitous parsing of date strings. It is intended to hold
8756 the last-modified date of the resource (if applicable). An
8757 update_mtime() routine has also been added to advance it if
8758 appropriate. [Roy Fielding, Ken Coar]
8760 *) SECURITY: If a htaccess file can not be read due to bad permissions,
8761 deny access to the directory with a HTTP_FORBIDDEN. The previous
8762 behavior was to ignore the htaccess file if it could not be read.
8763 This change may make some setups with unreadable htaccess files
8764 stop working. [Marc Slemko] PR#817
8766 *) Add aplog_error() providing a mechanism to define levels of
8767 verbosity to the server error logging. This addition also provides
8768 the ability to log errors using syslogd. Error logging is configurable
8769 on a per-server basis using the LogLevel directive. Conversion
8770 of log_*() in progress. [Randy Terbush]
8772 *) Further enhance aplog_error() to not log filename, line number, and
8773 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
8775 *) WIN32: Canonicalise filenames under Win32. Short filenames are
8776 converted to long ones. Backslashes are converted to forward
8777 slashes. Case is converted to lower. Parts of URLs that do not
8778 correspond to files are left completely alone. [Ben Laurie]
8780 *) PORT: 2 new OSs added to the list of ports:
8781 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
8782 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
8784 *) Add the server version (SERVER_VERSION macro) to the "server
8785 configured and running" entry in the error_log. Also build an
8786 object file at link-time that contains the current time
8787 (SERVER_BUILT global const char[]), and include that in the
8790 *) Set r->headers_out when sending responses from the proxy.
8791 This fixes things such as the logging of headers sent from
8792 the proxy. [Marc Slemko] PR#659
8794 *) support/httpd_monitor is no longer distributed because the
8795 scoreboard should not be file based if at all possible. Use
8796 mod_status to see current server snapshot.
8798 *) (set_file_slot): New function, allowing auth directives to be
8799 independent of the server root, so the server documents can be
8800 moved to a different directory or machine more easily.
8801 [David J. MacKenzie]
8803 *) If no TransferLog is given explicitly, decline
8804 to log. This supports coexistence with other logging modules,
8805 such as the custom one that UUNET uses. [David J. MacKenzie]
8807 *) Check for titles in server-parsed HTML files.
8808 Ignore leading newlines and returns in titles. The old behavior
8809 of replacing a newline after <title> with a space causes the
8810 title to be misaligned in the listing. [David J. MacKenzie]
8812 *) Change mod_cern_meta to be configurable on a per-directory basis.
8813 [David J. MacKenzie]
8815 *) Add 'Include' directive to allow inclusion of configuration
8816 files within configuration files. [Randy Terbush]
8818 *) Proxy errors on connect() are logged to the error_log (nothing
8819 new); now they include the IP address and port that failed
8820 (*that's* new). [Ken Coar, Marc Slemko] PR#352
8822 *) Various architectures now define USE_MMAP_FILES which causes
8823 the server to use mmap() for static files. There are two
8824 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
8825 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
8826 number of bytes written in one cycle from a single mmap()d object,
8827 default 32768). [Dean Gaudet]
8829 *) API: Added post_read_request API phase which is run right after reading
8830 the request from a client, or right after an internal redirect. It is
8831 useful for modules setting environment variables that depend only on
8832 the headers/contents of the request. It does not run during subrequests
8833 because subrequests inherit pretty much everything from the main
8834 request. [Dean Gaudet]
8836 *) Added mod_unique_id which is used to generate a unique identifier for
8837 each hit, available in the environment variable UNIQUE_ID.
8840 *) init_modules is now called after the error logs have been opened. This
8841 allows modules to emit information messages into the error logs.
8844 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8845 information for case where proxy module is not available. [Marc Slemko]
8847 *) PORT: Apache has need for mutexes to serialize its children around
8848 accept. In prior versions either fcntl file locking or flock file
8849 locking were used. The method is chosen by the definition of
8850 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
8851 and FLOCK for flock(). New options have been added:
8852 - SYSVSEM to use System V style semaphores
8853 - PTHREAD to use POSIX threads (appears to work on Solaris only)
8854 - USLOCK to use IRIX uslock
8855 Based on timing various techniques, the following changes were made
8857 - Linux 2.x uses flock instead of fcntl
8858 - Solaris 2.x uses pthreads
8859 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
8860 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
8861 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
8862 Martijn Koster <m.koster@pobox.com>]
8864 *) PORT: The semantics of accept/select make it very desirable to use
8865 mutexes to serialize accept when multiple Listens are in use. But
8866 in the case where only a single socket is open it is sometimes
8867 redundant to serialize accept(). Not all unixes do a good job with
8868 potentially dozens of children blocked on accept() on the same
8869 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
8870 the server will avoid serialization when listening on only one socket,
8871 and use serialization when listening on multiple sockets.
8872 [Dean Gaudet] PR#467
8874 *) Configure changes: TestLib replaced by TestCompile, which has
8875 some additional capability (such as doing a sanity check of
8876 the compiler and flags selected); the version of Solaris is now
8877 available via the #define value of SOLARIS2; IRIX n32bit libs
8878 now supported and selectable by new Configuration Rule: IRIXN32;
8879 We no longer default to -O2 optimization. [Jim Jagielski]
8881 *) Updated Configure: Configuration now uses AddModule to specify
8882 module source or binary file location, relative to src directory.
8883 Modules can be dropped into modules/extra, or in their own
8884 directory, and modules can come with a Makefile or Configure can
8885 create one. Modules can add compiler or library information to
8886 generated Makefiles. [Paul Sutton]
8888 *) Source core re-organisation: distributed modules are now in
8889 modules/standard. All other source code is in main. OS-specific
8890 code is in os/{unix,emx,win32} directories. [Paul Sutton]
8892 *) mod_browser has been removed, since it's replaced by mod_setenvif.
8895 *) Fix another long-standing bug in sub_req_lookup_file where it would
8896 happily skip past access checks on subdirectories looked up with
8897 relative paths. (It's used by mod_dir, mod_negotiation,
8898 and mod_include.) [Dean Gaudet]
8900 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
8901 N is the number of <Directory> sections, and M is the number of
8902 components in the filename of an object.
8904 To achieve this optimization the following config changes were made:
8905 - Wildcards (* and ?, not the regex forms) in <Directory>s,
8906 <Files>s, and <Location>s now treat a slash as a special
8907 character. For example "/home/*/public_html" previously would
8908 match "/home/a/andrew/public_html", now it only matches things
8909 like "/home/bob/public_html". This mimics /bin/sh behaviour.
8910 - It's possible now to use [] wildcarding in <Directory>, <Files>
8912 - Regex <Directory>s are applied after all non-regex <Directory>s.
8916 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
8917 and corrupted paths. [Dean Gaudet]
8919 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
8920 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
8921 be accessed now via backreferences $1..$9 in RewriteConds test-against
8922 strings in addition to RewriteRules subst string. Second the grouped
8923 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
8924 via backreferences %1..%9 both in following RewriteCond test-against
8925 strings and RewriteRules subst string. This provides maximum flexibility
8926 through the use of backreferences.
8927 Additionally the rewriting engine was cleaned up by putting common
8928 code to the new expand_backrefs_inbuffer() function.
8929 [Ralf S. Engelschall]
8931 *) When merging the main server's <Directory> and <Location> sections into
8932 a vhost, put the main server's first and the vhost's second. Otherwise
8933 the vhost can't override the main server. [Dean Gaudet] PR#717
8935 *) The <Directory> code would merge and re-merge the same section after
8936 a match was found, possibly causing problems with some modules.
8939 *) ip-based vhosts are stored and queried using a hashing function, which
8940 has been shown to improve performance on servers with many ip-vhosts.
8941 Some other changes had to be made to accommodate this:
8942 - the * address for vhosts now behaves like _default_
8943 - the matching process now is:
8944 - match an ip-vhost directly via hash (possibly matches main
8946 - if that fails, just pretend it matched the main server
8947 - if so far only the main server has been matched, perform
8948 name-based lookups (ServerName, ServerAlias, ServerPath)
8949 *only on name-based vhosts*
8950 - if they fail, look for _default_ vhosts
8951 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
8953 *) dbmmanage overhaul:
8954 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
8955 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
8956 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
8957 - provide better seed for rand
8958 - prompt for password as per getpass(3) (turn off echo, read from
8960 - use "newstyle" crypt based on $Config{osname} ($^O)
8961 - will not add a user if already in database, use new `update' command
8963 - added `check' command to check a users' password
8964 - added `import' command to convert existing password text-files or
8965 dbm files exported with `view'
8966 - more descriptive usage, general cleanup, 'use strict' clean, etc.
8969 *) Added psocket() which is a pool form of socket(), various places within
8970 the proxy weren't properly blocking alarms while registering the cleanup
8971 for its sockets. bclose() now uses pclose() and pclosesocket(). There
8972 was a bug where the client socket was being close()d twice due a still
8973 registered cleanup. [Dean Gaudet]
8975 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
8978 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
8979 [Jason Venner <jason@idiom.com>] PR#667
8981 *) Enable ``=""'' for RewriteCond directives to match against
8982 the empty string. This is the preferred way instead of ``^$''.
8983 [Ralf S. Engelschall]
8985 *) Fixed an infinite loop in mod_imap for references above the server root
8986 [Dean Gaudet] PR#748
8988 *) mod_proxy now has a ReceiveBufferSize directive, similar to
8989 SendBufferSize, so that the TCP window can be set appropriately
8990 for LFNs. [Phillip A. Prindeville]
8992 *) mod_browser has been replaced by the more general mod_setenvif
8993 (courtesy of Paul Sutton). BrowserMatch* directives are still
8994 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
8995 UnSetEnvIfZero directives. [Ken Coar]
8997 *) "HostnameLookups double" forces double-reverse DNS to succeed in
8998 order for remote_host to be set (for logging, or for the env var
8999 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
9002 *) mod_access overhaul:
9003 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
9004 and cidr syntax (i.e. 10.1.0.0/16). PR#762
9005 - Critical path was sped up by pre-computing a few things at config time.
9006 - The undocumented syntax "allow user-agents" was removed,
9007 the replacement is "allow from env=foobar" combined with mod_browser.
9008 - When used with hostnames it now forces a double-reverse lookup
9009 no matter what the directory settings are. This double-reverse
9010 doesn't affect any of the other routines that use the remote
9011 hostname. In particular it's still passed to CGIs and the log
9012 without the double-reverse check. Related PR#860.
9015 *) When a large bwrite() occurs (larger than the internal buffer size),
9016 while there is already something in the buffer, apache will combine
9017 the large write and the buffer into a single writev(). (This is
9018 in anticipation of using mmap() for reading files.)
9021 *) In obscure cases where a partial socket write occurred while chunking,
9022 Apache would omit the chunk header/footer on the next block. Cleaned
9023 up other bugs/inconsistencies in error conditions in buff.c. Fixed
9024 a bug where a long pause in DNS lookups could cause the last packet
9025 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
9027 *) API: Added child_exit function to module structure. This is called
9028 once per "heavy-weight process" just before a server child exit()'s
9029 e.g. when max_requests_per_child is reached, etc.
9030 [Doug MacEachern, Dean Gaudet]
9032 *) mod_include cleanup showed that handle_else was being used to handle
9033 endif. It didn't cause problems, but it was cleaned up too.
9036 *) mod_cern_meta would attempt to find meta files for the directory itself
9037 in some cases, but not in others. It now avoids it in all cases.
9040 *) mod_mime_magic would core dump if there was a decompression error.
9041 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
9043 *) PORT: some variants of DGUX require -lsocket -lnsl
9044 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
9046 *) mod_autoindex now allows sorting of FancyIndexed directory listings
9047 by the various fields (name, size, et cetera), either in ascending
9048 or descending order. Just click on the column header. [Ken Coar]
9050 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
9051 CPUs like the Alpha. Apache still stores ints in pointers, but that's
9052 the relatively safe direction. [Dean Gaudet] PR#344
9054 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
9055 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
9057 *) child_main avoids an unneeded call to select() when there is only one
9058 listening socket. [Dean Gaudet]
9060 *) In the event that the server is starved for idle servers it will
9061 spawn 1, then 2, then 4, ..., then 32 servers each second,
9062 doubling each second. It'll also give a warning in the errorlog
9063 since the most common reason for this is a poor StartServers
9064 setting. The define MAX_SPAWN_RATE can be used to raise/lower
9065 the maximum. [Dean Gaudet]
9067 *) Apache now provides an effectively unbuffered connection for
9068 CGI scripts. This means that data will be sent to the client
9069 as soon as the CGI pauses or stops output; previously, Apache would
9070 buffer the output up to a fixed buffer size before sending, which
9071 could result in the user viewing an empty page until the CGI finished
9072 or output a complete buffer. It is no longer necessary to use an
9073 "nph-" CGI to get unbuffered output. Given that most CGIs are written
9074 in a language that by default does buffering (e.g. perl) this
9075 shouldn't have a detrimental effect on performance.
9077 "nph-" CGIs, which formerly provided a direct socket to the client
9078 without any server post-processing, were not fully compatible with
9079 HTTP/1.1 or SSL support. As such they would have had to implement
9080 the transport details, such as encryption or chunking, in order
9081 to work properly in certain situations. Now, the only difference
9082 between nph and non-nph scripts is "non-parsed headers".

9086 bread() will return whatever remained in the buffer prior to the
9087 switch. [Dean Gaudet]
9089 Changes with Apache 1.3a1
9091 *) Added another Configure helper script: TestLib. It determines
9092 if a specified library exists. [Jim Jagielski]
9094 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
9095 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
9098 *) PORT: Some architectures use size_t for various lengths in network
9099 functions such as accept(), and getsockname(). The definition
9100 NET_SIZE_T is used to control this. [Dean Gaudet]
9102 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
9103 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
9104 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
9106 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.

9109 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
9110 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
9111 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

9132 *) AddModuleInfo directive for mod_info which allows you to annotate
9133 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
9135 *) Added NoProxy directive to avoid using ProxyRemote for selected

9141 header to the remote host in the proxy. [Sameer Parekh and
9144 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
9145 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
9146 URLs, fixed rewritelog(), fixed forced response code handling on
9147 redirects from within .htaccess files, disabled pipe locking under
9148 braindead SunOS 4.1.x, allow env variables to be set even on rules with
9149 no substitution, bugfixed situations where HostnameLookups is off, made
9150 mod_rewrite more thread-safe for NT port and fixed problem when creating
9151 an empty query string via "xxx?".
9152 This update also removes the copyright of Ralf S. Engelschall,
9153 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
9154 exclusively copyrighted by the Apache Group now. This happened because
9155 the author now has gifted mod_rewrite exclusively to the Apache Group and
9156 no longer maintains an external version.

9159 *) API: Added child_init function to module structure. This is called
9160 once per "heavy-weight process" before any requests are handled.
9161 See http_config.h for more details. [Dean Gaudet]
9163 *) Anonymous_LogEmail was logging on each subrequest.
9164 [Dean Gaudet] PR#421, 868
9166 *) API: Added is_initial_req() which tests if the request being
9167 processed is the initial request, or a subrequest.
9170 *) Extended SSI (mod_include) now handles additional relops for
9171 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
9173 *) Configure fixed to correctly propagate user-selected options and
9174 settings (such as CC and OPTIM) to Makefiles other than
9175 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
9177 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
9178 directory indices to start with the contents of the HeaderName file
9179 if there is one. If there isn't one, the behaviour is unchanged.
9180 [Ken Coar, Roy Fielding, Andrey A. Chernov]
9182 *) WIN32: Modules can now be dynamically loaded DLLs using the
9183 LoadModule/LoadFile directives. Note that module DLLs must be
9184 compiled with the multithreaded DLL version of the runtime library.
9185 [Alexei Kosut and Ben Laurie]
9187 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
9188 This allows the admin to completely remove automatic indexing
9189 from the server, while still supporting the basic functions of
9190 trailing-slash redirects and DirectoryIndex files. Note that if
9191 you're carrying over an old Configuration file and you use directory
9192 indexing then you'll want to add:
9194 Module autoindex_module mod_autoindex.o
9196 before mod_dir in your Configuration. [Dean Gaudet]
9198 *) popendir/pclosedir created to properly protect directory scanning.
9199 [Dean Gaudet] PR#525
9201 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
9202 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
9203 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
9206 *) The AccessFileName directive can now take more than one filename.
9207 ["Lou D. Langholtz" <ldl@usi.utah.edu>]

9210 of a file if the extension is unknown. Based on the unix file(1)
9211 command. [Ian Kluft <ikluft@cisco.com>]

9217 main httpd process's PID. [Jim Jagielski]
9219 *) Makefile.nt added - to build all the bits from the command line:
9220 nmake -f Makefile.nt
9221 Doesn't yet work properly. [Ben Laurie]
9223 *) Default text of 404 error is now "Not Found" rather than the
9224 potentially misleading "File Not Found". [Ken Coar]
9226 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
9227 for the net if we require people that actually need this data to
9228 enable it. [Linus Torvalds]
9230 *) directory_walk() is an expensive function, keep a little more state to
9231 avoid needless string counting. Add two new functions make_dirstr_parent
9232 and make_dirstr_prefix which replace all existing uses of make_dirstr.
9233 The new functions are a little less general than make_dirstr, but
9234 work more efficiently (less memory, less string counting).
9237 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
9238 to LDFLAGS) to avoid complications with lex rules in make files.
9239 [Dean Gaudet] PR#372
9241 *) run_method optimized to avoid needless scanning over NULLs in the
9242 module list. [Dean Gaudet]
9244 *) Revamp of (unix) scoreboard management code such that it avoids
9245 unnecessary traversals of the scoreboard on each hit. This is
9246 particularly important for high volume sites with a large
9247 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
9248 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
9249 httpd.h. [Dean Gaudet]
9251 *) In configurations using multiple Listen statements it was possible for
9252 busy sockets to starve other sockets of service. [Dean Gaudet]
9254 *) Added hook so standalone_main can be replaced at compile time
9255 (define STANDALONE_MAIN)
9258 *) Lowest-level read/write functions in buff.c will be replaced with
9259 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
9260 compile time. The default sfio discipline will behave as apache
9261 would without sfio compiled in.
9264 *) Enhance UserDir directive (mod_userdir) to accept a list of
9265 usernames for the 'disable' keyword, and add 'enable user...' to
9266 selectively *en*able userdirs if they're globally disabled.
9269 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
9270 will work with Netscape dbm files. (dbmmanage will probably not
9271 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
9273 *) Add a ListenBacklog directive to control the backlog parameter
9274 passed to listen(). Also change the default to 511 from 512.
9277 *) API: A new handler response DONE which informs apache that the
9278 request has been handled and it can finish off quickly, similar to
9279 how it handles errors. [Rob Hartill]
9281 *) Turn off chunked encoding after sending terminating chunk/footer
9282 so that we can't do it twice by accident. [Roy Fielding]
9284 *) mod_expire also issues Cache-Control: max-age headers.
9287 *) API: Added kill_only_once option for free_proc_chain so that it won't
9288 aggressively try to kill off specific children. For fastcgi.
9289 [Stanley Gambarin <gambarin@OpenMarket.com>]
9291 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
9293 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
9294 When used together, these cause mod_dir to emit HEIGHT and WIDTH
9295 attributes in the FancyIndexing IMG tags. [Ken Coar]
9297 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
9299 *) PORT: Added Windows NT support
9300 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
9302 Changes with Apache 1.2.6
9304 *) mod_include when using XBitHack Full would send ETags in addition to
9305 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
9306 [Dean Gaudet] PR#1133
9308 *) SECURITY: When a client connects to a particular port/addr, and
9309 gives a Host: header ensure that the virtual host requested can
9310 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
9312 *) Support virtual hosts with wildcard port and/or multiple ports
9313 properly. [Ed Korthof <ed@organic.com>]
9315 *) Fixed some case-sensitivity issues according to RFC2068.
9318 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
9319 and mod_include.c. [Dean Gaudet]
9321 *) Variable 'cwd' was being used pointlessly before being set.
9324 *) SIGURG doesn't exist on all platforms.
9325 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
9327 *) When an error occurs during a POST, or other operation with a
9328 request body, the body has to be read from the net before allowing
9329 a keepalive session to continue. [Roy Fielding] PR#1399
9331 *) When an error occurs in fcntl() locking suggest the user look up
9332 the docs for LockFile. [Dean Gaudet]
9334 *) table_set() and table_unset() did not deal correctly with
9335 multiple occurrences of the same key. [Stephen Scheck
9336 <sscheck@infonex.net>, Ben Laurie] PR#1604
9338 *) send_fd_length() did not calculate total_bytes_sent properly in error
9339 cases. [Ben Reser <breser@regnow.com>] PR#1366
9341 *) r->connection->user was allocated in the wrong pool causing corruption
9342 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
9344 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
9345 Also removed the auto-generated link to www.apache.org that was the
9346 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
9348 *) Multiple "close" tokens may have been set in the "Connection"
9349 header, not an error, but a waste.
9350 [Ronald.Tschalaer@psi.ch] PR#1683
9352 *) "basic" and "digest" auth tokens should be tested case-insensitive.
9353 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
9355 *) It appears the "257th byte" bug (see
9356 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
9357 at the 256th byte as well. Fixed. [Dean Gaudet]
9359 *) mod_rewrite would not handle %3f properly in some situations.
9362 *) Apache could generate improperly chunked HTTP/1.1 responses when
9363 the bputc() or rputc() functions were used by modules (such as
9364 mod_include). [Dean Gaudet]
9366 *) #ifdef wrap a few #defines in httpd.h to make life easier on
9367 some ports. [Ralf Engelschall]
9369 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
9371 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
9373 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
9375 Changes with Apache 1.2.5
9377 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
9378 only an issue on systems without a MAXDNAME define or where
9379 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
9381 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
9384 *) Fix core dump in the ftp proxy when reading incorrectly formatted
9385 directory listings. [Marc Slemko]
9387 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
9390 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
9391 is used to read various types of files such as htaccess and
9392 htpasswd files. [Marc Slemko]
9394 *) SECURITY: Ensure that the buffer returned by ht_time is always
9395 properly null terminated. [Marc Slemko]
9397 *) SECURITY: General mod_include cleanup, including fixing several
9398 possible buffer overflows and a possible infinite loop. This cleanup
9399 was done against 1.3 code and then backported to 1.2, the result
9400 is a large difference (due to indentation cleanup in 1.3 code).
9401 Users interested in seeing a smaller set of relevant differences
9402 should consider comparing against src/modules/standard/mod_include.c
9403 from the 1.3b3 release. Non-indentation changes to mod_include
9404 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
9406 *) SECURITY: Numerous changes to mod_imap in a general cleanup
9407 including fixing a possible buffer overflow. This cleanup also
9408 was done with 1.3 code as a basis, see the the previous note
9409 about mod_include. [Dean Gaudet]
9411 *) SECURITY: If a htaccess file can not be read due to bad
9412 permissions, deny access to the directory with a HTTP_FORBIDDEN.
9413 The previous behavior was to ignore the htaccess file if it could not
9414 be read. This change may make some setups with unreadable
9415 htaccess files stop working. PR#817 [Marc Slemko]
9417 *) SECURITY: no2slash() was O(n^2) in the length of the input.
9418 Make it O(n). This inefficiency could be used to mount a denial
9419 of service attack against the Apache server. Thanks to

9427 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
9429 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
9431 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
9432 r->filename. Since those two are meant to be in sync with each other
9433 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
9435 *) mod_include did not properly handle all possible redirects from sub-
9436 requests. [Ken Coar]

9439 jmpbuffer. [Dean Gaudet] PR#1064

9442 reporting a select error over and over.
9443 [Rick Franchuk <rickf@transpect.net>] PR#1107
9445 Changes with Apache 1.2.4
9447 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
9448 always making requests with the full-URI instead of just the URI path.
9449 [Marc Slemko, Roy Fielding]
9451 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
9452 on this platform. [Marc Slemko]
9454 Changes with Apache 1.2.3
9456 *) The request to a remote proxy was mangled if it was generated as the
9457 result of a ProxyPass directive. URL schemes other than http:// were not
9458 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
9459 PR#812 [Lars Eilebrecht]
9461 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
9462 information for case where proxy module is not available. [Marc Slemko]
9464 *) Force proxy to always respond as HTTP/1.0, which it was failing to
9465 do for errors and cached responses. [Roy Fielding]
9467 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
9469 Changes with Apache 1.2.2 [not released]
9471 *) Fixed another long-standing bug in sub_req_lookup_file where it would
9472 happily skip past access checks on subdirectories looked up with relative
9473 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
9476 *) Add lockfile name to error message printed out when
9477 USE_FLOCK_SERIALIZED_ACCEPT is defined.
9480 *) Enhanced the chunking and error handling inside the buffer functions.
9481 [Dean Gaudet, Roy Fielding]
9483 *) When merging the main server's <Directory> and <Location> sections into
9484 a vhost, put the main server's first and the vhost's second. Otherwise
9485 the vhost can't override the main server. [Dean Gaudet] PR#717
9487 *) The <Directory> code would merge and re-merge the same section after
9488 a match was found, possibly causing problems with some modules.
9491 *) Fixed an infinite loop in mod_imap for references above the server root.
9492 [Dean Gaudet] PR#748
9494 *) mod_include cleanup showed that handle_else was being used to handle
9495 endif. It didn't cause problems, but it was cleaned up too.
9498 *) Last official synchronization of mod_rewrite with author version (because
9499 mod_rewrite is now directly developed by the author at the Apache Group):
9500 o added diff between mod_rewrite 3.0.6+ and 3.0.9
9501 minus WIN32/NT stuff, but plus copyright removement.
9503 - workaround for detecting infinite rewriting loops
9504 - fixed setting of env vars when "-" is used as subst string

9507 - kludge to disable locking on pipes under braindead SunOS
9508 - fix for rewritelog in cases where remote hostname is unknown
9509 - fixed totally damaged request_rec walk-back loop
9510 o remove static from local data and add static to global ones.
9511 o replaced ugly proxy finding stuff by simple
9512 find_linked_module("mod_proxy") call.
9513 o added missing negation char on rewritelog()

9545 *) API: In HTTP/1.1, whether or not a request message contains a body
9546 is independent of the request method and based solely on the presence
9547 of a Content-Length or Transfer-Encoding. Therefore, our default
9548 handlers need to be prepared to read a body even if they don't know
9549 what to do with it; otherwise, the body would be mistaken for the
9550 next request on a persistent connection. discard_request_body()

9604 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
9605 which keeps all non-FILE * descriptors above 255. On all systems
9606 this should make supporting large numbers of vhosts with many open

9660 Changes with Apache 1.2
9662 Changes with Apache 1.2b11
9664 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
9666 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
9667 [Doug MacEachern, Rob Hartill]
9669 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
9670 reading from one buffer and writing to another, at least until it has
9671 a custom timeout handler. [Roy Fielding and Petr Lampa]
9673 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
9674 apparently due to a mismatch between sigaction and setjmp.
9675 [Roy Fielding] PR#502
9677 *) Log correct status code if we timeout before receiving a request (408)
9678 or if we received a request-line that was too long to process (414).
9679 [Ed Korthof and Roy Fielding] PR#601
9681 *) Virtual hosts with the same ServerName, but on different ports, were
9682 not being selected properly. [Ed Korthof]
9684 *) Added code to return the requested IP address from proxy_host2addr()
9685 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
9686 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
9687 [Chuck Murcko] PR#614
9689 *) If multiple requests on a single connection are used to retrieve
9690 data from different virtual hosts, the virtual host list would be
9691 scanned starting with the most recently used VH instead of the first,
9692 causing most virtual hosts to be ignored.
9693 [Paul Sutton and Martin Mares] PR#610
9695 *) The OS/2 handling of process group was broken by a porting patch for
9696 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
9698 *) Inherit virtual server port from main server if none (or "*") is
9699 given for VirtualHost. [Dean Gaudet] PR#576
9701 *) If the lookup for a DirectoryIndex name with content negotiation
9702 has found matching variants, but none are acceptable, return the
9703 negotiation result if there are no more DirectoryIndex names to lookup.
9704 [Petr Lampa and Roy Fielding]
9706 *) If a soft_timeout occurs after keepalive is set, then the main child
9707 loop would try to read another request even though the connection
9708 has been aborted. [Roy Fielding]
9710 *) Configure changes: Allow for whitespace at the start of a
9711 Module declaration. Also, be more understanding about the
9712 CC=/OPTIM= format in Configuration. Finally, fix compiler
9713 flags if using HP-UX's cc compiler. [Jim Jagielski]
9715 *) Subrequests and internal redirects now inherit the_request from the
9716 original request-line. [Roy Fielding]
9718 *) Test for error conditions before creating output header fields, since
9719 we don't want the error message to include those fields. Likewise,
9720 reset the content_language(s) and content_encoding of the response
9721 before generating or redirecting to an error message, since the new
9722 message will have its own Content-* definitions. [Dean Gaudet]
9724 *) Restored the semantics of headers_out (headers sent only with 200..299
9725 and 304 responses) and err_headers_out (headers sent with all responses).
9726 Avoid the overhead of copying tables if err_headers_out is empty
9727 (the usual case). [Roy Fielding]
9729 *) Fixed a couple places where a check for the default Content-Type was
9730 not properly checking both the value configured by the DefaultType
9731 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
9732 of DEFAULT_TYPE to match the documented default (text/plain).
9733 [Dean Gaudet] PR#506
9735 *) Escape the HTML-sensitive characters in the Request-URI that is
9736 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
9738 *) Properly initialize the flock structures used by the mutex locking
9739 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
9742 *) The method for determining PATH_INFO has been restored to the pre-1.2b
9743 (and NCSA httpd) definition wherein it was the extra path info beyond
9744 the CGI script filename. The environment variable FILEPATH_INFO has
9745 been removed, and instead we supply the original REQUEST_URI to any
9746 script that wants to be Apache-specific and needs the real URI path.
9747 This solves a problem with existing scripts that use extra path info
9748 in the ScriptAlias directive to pass options to the CGI script.
9751 *) The _default_ change in 1.2b10 will change the behaviour on configs
9752 that use multiple Listen statements for listening on multiple ports.
9753 But that change is necessary to make _default_ consistent with other
9754 forms of <VirtualHost>. It requires such configs to be modified
9755 to use <VirtualHost _default_:*>. The documentation has been
9756 updated. [Dean Gaudet] PR#530
9758 *) If an ErrorDocument CGI script is used to respond to an error
9759 generated by another CGI script which has already read the message
9760 body of the request, the server would block trying to read the
9761 message body again. [Rob Hartill]
9763 *) signal() replacement conflicted with a define on QNX (and potentially
9764 other platforms). Fixed. [Ben Laurie] PR#512
9766 Changes with Apache 1.2b10
9768 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
9769 to be configured via -D in Configuration. [Dean Gaudet] PR#449
9771 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
9773 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
9775 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
9776 config, in case the hostent struct returned is trash.
9777 [Chuck Murcko] PR #491
9779 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
9780 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
9782 Changes with Apache 1.2b9 [never announced]
9784 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
9785 changes and in anticipation of 1.2 final release. [Roy Fielding]
9787 *) Fix problem with scripts not receiving a SIGPIPE when client drops
9788 the connection (e.g., when user presses Stop). Apache will now stop
9789 trying to send a message body immediately after an error from write.
9790 [Roy Fielding and Nathan Kurz] PR#335
9792 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
9793 than mod_alias, and mod_alias has higher priority than mod_proxy;
9794 rearranged other modules to enhance understanding of their purpose
9795 and relative order (and maybe even reduce some overhead).
9796 [Roy Fielding and Sameer Parekh]
9798 *) Fix graceful restart. Eliminate many signal-related race
9799 conditions in both forms of restart, and in SIGTERM. See
9800 htdocs/manual/stopping.html for details on stopping and
9801 restarting the parent. [Dean Gaudet]
9803 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
9804 memory allocator to avoid a behaviour that required extra blocks to
9805 be allocated. [Dean Gaudet]
9807 *) Allow suexec to access files relative to current directory but not
9808 above. (Excluding leading / or any .. directory.) [Ken Coar]
9811 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
9812 PR#367, 368, 354, 453
9814 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
9815 while obtaining the /~user and save the username in a separate data
9816 area so that it won't be overwritten by the call to getgrgid(), and
9817 fix some misuse of the pool string allocation functions. Also fixes
9818 a general problem with parsing URL query info into args for CGI scripts.
9819 [Roy Fielding] PR#339, 367, 354, 453
9821 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
9823 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
9825 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
9826 AuthDBAuthoritative. [Marc Slemko] PR#420
9828 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
9830 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
9831 object that can't be PUT, or FOOBAR for some method FOOBAR that
9832 apache doesn't know about at all). Log 404s that occur in mod_include.
9833 [Paul Sutton, John Van Essen]
9835 *) If a soft timeout (or lingerout) occurs while trying to flush a
9836 buffer or write inside buff.c or fread'ing from a CGI's output,
9837 then the timeout would be ignored. [Roy Fielding] PR#373
9839 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
9840 parsing of headers. If the terminating empty-line CRLF occurs starting
9841 at the 256th or 257th byte of output, then Navigator will think a normal
9842 image is invalid. We are guessing that this is because their initial
9843 read of a new request uses a 256 byte buffer. We check the bytes written
9844 so far and, if we are about to tickle the bug, we instead insert a
9845 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
9847 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
9848 of an external redirection. [Roy Fielding and Paul Sutton]
9850 *) Configure would create a broken Makefile if the configuration file
9851 contained a commented-out Rule. [Roy Fielding]
9853 *) Promote per_dir_config and subprocess_env from the subrequest to the
9854 main request in mod_negotiation. In particular this fixes a bug
9855 where <Files> sections wouldn't properly apply to negotiated content.
9858 *) Fix a potential deadlock in mod_cgi script_err handling.
9859 [Ralf S. Engelschall]
9861 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
9864 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
9865 .htaccess files because the RewriteBase was not replaced correctly.
9866 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
9867 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
9869 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
9870 1.x the settings are those of pre-1.2b8. For 2.x we include
9871 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
9872 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
9873 [Dean Gaudet] PR#336, PR#340
9875 *) Redirect did not preserve ?query_strings when present in the client's
9876 request. [Dean Gaudet]
9878 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
9880 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
9882 *) Add UnixWare compile/install instructions. [Chuck Murcko]
9884 *) Add mod_example (illustration of API techniques). [Ken Coar]
9886 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
9888 *) Improve handling of directories when filenames have spaces in them.
9891 *) For hosts with multiple IP addresses, try all additional addresses if
9892 necessary to get a connect. Fail only if hostent address list is
9893 exhausted. [Chuck Murcko]
9895 *) More signed/unsigned port fixes. [Dean Gaudet]
9897 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
9900 Changes with Apache 1.2b8
9902 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
9903 to it. [Marc Slemko]
9905 *) The addition of <Location> and <File> directives made the
9906 sub_req_lookup_simple() function bogus, so we now handle
9907 the special cases directly. [Dean Gaudet]
9909 *) We now try to log where the server is dumping core when a fatal
9910 signal is received. [Ken Coar]
9912 *) Improved lingering_close by adding a special timeout, removing the
9913 spurious log messages, removing the nonblocking settings (they
9914 are not needed with the better timeout), and adding commentary
9915 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
9916 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
9918 *) Send error messages about setsockopt failures to the server error
9919 log instead of stderr. [Roy Fielding]
9921 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
9923 *) Stopgap solution for CGI 3-second delay with server-side includes: if
9924 processing a subrequest, allocate memory from r->main->pool instead
9925 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
9926 in the middle of an SSI request. [Dean Gaudet] PR #122
9928 *) Fixed status of response when POST is received for a nonexistent URL
9929 (was sending 405, now 404) and when any method is sent with a
9930 full-URI that doesn't match the server and the server is not acting
9931 as a proxy (was sending 501, now 403). [Roy Fielding]
9933 *) Host port changed to unsigned short. [Ken Coar] PR #276
9935 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
9937 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
9939 *) Report extra info from errno with many errors that cause httpd to exit.
9940 spawn_child, popenf, and pclosef now have valid errno returns in the
9941 event of an error. Correct problems where errno was stomped on
9942 before being reported. [Dean Gaudet]
9944 *) In the proxy, if the cache filesystem was full, garbage_coll() was
9945 never called, and thus the filesystem would remain full indefinitely.
9946 We now also remove incomplete cache files left if the origin server
9947 didn't send a Content-Length header and either the client has aborted
9948 transfer or bwrite() to client has failed. [Petr Lampa]
9950 *) Fixed the handling of module and script-added header fields.
9951 Improved the interface for sending header fields and reduced
9952 the duplication of code between sending okay responses and errors.
9953 We now always send both headers_out and err_headers_out, and
9954 ensure that the server-reserved fields are not being overridden,
9955 while not overriding those that are not reserved. [Roy Fielding]
9957 *) Moved transparent content negotiation fields to err_headers_out
9958 to reflect above changes. [Petr Lampa]
9960 *) Fixed the determination of whether or not we should make the
9961 connection persistent for all of the cases where some other part
9962 of the server has already indicated that we should not. Also
9963 improved the ordering of the test so that chunked encoding will
9964 be set whenever it is desired instead of only when KeepAlive
9965 is enabled. Added persistent connection capability for most error
9966 responses (those that do not indicate a bad input stream) when
9967 accessed by an HTTP/1.1 client. [Roy Fielding]
9969 *) Added missing timeouts for sending header fields, error responses,
9970 and the last chunk of chunked encoding, each of which could have
9971 resulted in a process being stuck in write forever. Using soft_timeout
9972 requires that the sender check for an aborted connection rather than
9973 continuing after an EINTR. Timeouts that used to be initiated before
9974 send_http_header (and never killed) are now initiated only within or
9975 around the routines that actually do the sending, and not allowed to
9976 propagate above the caller. [Roy Fielding]
9978 *) mod_auth_anon required an @ or a . in the email address, not both.
9981 *) per_dir_defaults weren't set correctly until directory_walk for
9982 name-based vhosts. This fixes an obscure bug with the wrong config
9983 info being used for vhosts that share the same ip as the server.
9986 *) Improved generation of modules/Makefile to be more generic for
9987 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
9989 *) Generate makefile dependency for Configuration based on the actual
9990 name given when running the Configure process. [Dean Gaudet]
9992 *) Fixed problem with vhost error log not being set prior to
9993 initializing virtual hosts. [Dean Gaudet]
9995 *) Fixed infinite loop when a trailing slash is included after a type map
9996 file URL (extra path info). [Petr Lampa]
9998 *) Fixed server status updating of per-connection counters. [Roy Fielding]
10000 *) Add documentation for DNS issues (reliability and security), and try
10001 to explain the virtual host matching process. [Dean Gaudet]
10003 *) Try to continue gracefully by disabling the vhost if a DNS lookup
10004 fails while parsing the configuration file. [Dean Gaudet]
10006 *) Improved calls to setsockopt. [Roy Fielding]
10008 *) Negotiation changes: Don't output empty content-type in variant list;
10009 Output charset in variant list; Return sooner from handle_multi() if
10010 no variants found; Add handling of '*' wildcard in Accept-Charset.
10011 [Petr Lampa and Paul Sutton]
10013 *) Fixed overlaying of request/sub-request notes and headers in
10014 mod_negotiation. [Dean Gaudet]
10016 *) If two variants' charset quality are equal and one is the default
10017 charset (iso-8859-1), then prefer the variant that was specifically
10018 listed in Accept-Charset instead of the default. [Petr Lampa]
10020 *) Memory allocation problem in push_array() -- it would corrupt memory
10021 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
10023 *) invoke_handler() doesn't handle mime arguments in content-type
10024 [Petr Lampa] PR#160
10026 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
10029 *) Fixed problem with ErrorDocument not working for virtual hosts
10030 due to one of the performance changes in 1.2b7. [Dean Gaudet]
10032 *) Log an error message if we get a request header that is too long,
10033 since it may indicate a buffer overflow attack. [Marc Slemko]
10035 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
10036 not reject URLs without a double-slash, as per RFC2068 section 3.2.
10037 [Ken Coar] PR #146, #187
10039 *) Added table entry placeholder for new header_parser callback
10040 in all of the distributed modules. [Ken Coar] PR #191
10042 *) Allow for cgi files without the .EXE extension on them under OS/2.
10043 [Garey Smiley] PR #59
10045 *) Fixed error message when resource is not found and URL contains
10046 path info. [Petr Lampa and Dean Gaudet] PR #40
10048 *) Fixed user and server confusion over what should be a virtual host
10049 and what is the main server, resulting in access to something
10050 other than the name defined in the virtualhost directive (but
10051 with the same IP address) failing. [Dean Gaudet]
10053 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
10054 AIX; improves the redirection stuff to enable the users to generally
10055 redirect to http, https, gopher and ftp; added TIME variable for
10056 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
10057 special patterns >STRING, <STRING and =STRING to RewriteCond, which
10058 can be used in conjunction with %{TIME} or other variables to create
10059 time-dependent rewriting rules. [Ralf S. Engelschall]
10061 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
10062 Module authors may need to adjust their code for proper cleanup to take
10063 place (that is, call note_cleanups_for_fd()). This change fixes problems
10064 with file descriptors being erroneously closed when the proxy module was
10065 in use. [Ben Laurie]
10067 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
10068 initgroups() to hose the group information needed for later
10069 comparisons. [Randy Terbush]
10071 *) Remove unnecessary call to va_end() in create_argv() which
10072 caused a SEGV on some systems.
10074 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
10077 *) Clear memory allocated for listeners. [Randy Terbush]
10079 *) Improved handling of IP address as a virtualhost address and
10080 introduced "_default_" as a synonym for the default vhost config.

10090 - replace protocol response numbers with symbols
10091 - save variant-list into main request notes
10092 - free allocated memory from subrequests
10093 - merge notes, headers_out and err_headers_out
10095 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
10096 "HTTP/#.# ###*" to be more lenient about what we accept.
10099 *) more proxy FTP bug fixes:
10100 - Changed send_dir() to remove user/passwd from displayed URL.
10101 - Changed login error messages to be more descriptive.
10102 - remove setting of SO_DEBUG socket option
10103 - Make ftp_getrc() more lenient about multiline responses,
10104 specifically, 230 responses which don't have continuation 230-
10105 on each line). These seem to be all NT FTP servers, and while
10106 perhaps questionable, they appear to be legal by RFC 959.
10107 - Add missing kill_timeout() after transfer to user completes.
10110 *) Fixed problem where a busy server could hang when restarting
10111 after being sent a SIGHUP due to child processes not exiting.
10114 *) Modify mod_include escaping so a '\' only signifies an escaped
10115 character if the next character is one that needs
10116 escaping. [Ben Laurie]
10118 *) Eliminated possible infinite loop in mod_imap when relative URLs are
10119 used with a 'base' directive that does not have a '/' in it.
10120 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
10122 *) Reduced the default timeout from 1200 seconds to 300, and the
10123 one in the sample configfile from 400 to 300. [Marc Slemko]
10125 *) Stop vbprintf from crashing if given a NULL string pointer;
10126 print (null) instead. [Ken Coar]
10128 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
10129 [Marc Slemko and Roy Fielding]
10131 *) Fixed problem with mod_cgi-generated internal redirects trying to
10132 read the request message-body twice. [Archie Cobbs and Roy Fielding]
10134 *) Reduced timeout on lingering close, removed possibility of a blocked
10135 read causing the child to hang, and stopped logging of errors if
10136 the socket is not connected (reset by client). [Roy Fielding]
10138 *) Rearranged main child loop to remove duplication of code in
10139 select/accept and keep-alive requests, fixed several bugs regarding
10140 checking scoreboard_image for exit indication and failure to
10141 account for all success conditions and trap all error conditions,
10142 prevented multiple flushes before closing the socket; close the entire
10143 socket buffer instead of just one descriptor, prevent logging of
10144 EPROTO and ECONNABORTED on platforms where supported, and generally
10145 improved readability. [Roy Fielding]
10147 *) Extensive performance improvements. Cleaned up inefficient use of
10148 auto initializers, multiple is_matchexp calls on a static string,
10149 and excessive merging of response_code_strings. [Dean Gaudet]
10151 *) Added double-buffering to mod_include to improve performance on
10152 server-side includes. [Marc Slemko]
10154 *) Several fixes for suexec wrapper. [Randy Terbush]
10155 - Make wrapper work for files on NFS filesystem.
10156 - Fix portability problem of MAXPATHLEN.
10157 - Fix array overrun problem in clean_env().
10158 - Fix allocation of PATH environment variable
10160 *) Removed extraneous blank line is description of mod_status chars.
10163 *) Logging of errors from the call_exec routine simply went nowhere,
10164 since the logfile fd has been closed, so now we send them to stderr.
10165 [Harald T. Alvestrand]
10167 *) Fixed core dump when DocumentRoot is a CGI.
10168 [Ben Laurie, reported by geddis@tesserae.com]
10170 *) Fixed potential file descriptor leak in mod_asis; updated it and
10171 http_core to use pfopen/pfclose instead of fopen/fclose.
10172 [Randy Terbush and Roy Fielding]
10174 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
10175 as the DEC Alpha which is 64-bit but uses 32-bit ints.
10176 [Dean Gaudet and Ken Coar]
10178 *) Return a 302 response code to the client when sending a redirect
10179 due to a missing trailing '/' on a directory instead of a 301; now
10180 it is cacheable. [Markus Gyger]
10182 *) Fix condition where, if a bad directive occurs in .htaccess, and
10183 sub_request() goes first to this directory, then log_reason() will
10184 SIGSEGV because it doesn't have initialized r->per_dir_config.
10185 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
10187 *) Fix handling of lang_index in is_variant_better(). This was
10188 causing problems which resulted in the server sending the
10189 wrong language document in some cases. [Petr Lampa]
10191 *) Remove free() from clean_env() in suexec wrapper. This was nuking
10192 the clean environment on some systems.
10194 *) Tweak byteserving code (e.g. serving PDF files) to work around
10195 bugs in Netscape Navigator and Microsoft Internet Explorer.
10196 Emit Content-Length header when sending multipart/byteranges.
10199 *) Port to HI-UX/WE2. [Nick Maclaren]
10201 *) Port to HP MPE operating system for HP 3000 machines
10202 [Mark Bixby <markb@cccd.edu>]
10204 *) Fixed bug which caused a segmentation fault if only one argument
10205 given to RLimit* directives. [Ed Korthof]
10207 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
10209 *) Improved buffered output to the client by delaying the flush decision
10210 until the BUFF code is actually about to read the next request.
10211 This fixes a problem introduced in 1.2b5 with clients that send
10212 an extra CRLF after a POST request. Also improved chunked output
10213 performance by combining writes using writev() and removing as
10214 many bflush() calls as possible. NOTE: Platforms without writev()
10215 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
10216 or Configure, unless we have already done so. [Dean Gaudet]
10218 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
10220 *) Fixed mod_info output corruption bug introduced by buffer overflow
10221 fixes. [Dean Gaudet]
10223 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
10224 for the special case of a 304 response. [Paul Sutton]
10226 *) Improved handling of TRACE method by bypassing normal method handling
10227 and header parsing routines; fixed Allow response to always allow TRACE.
10230 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
10232 *) Cleaned-up some of the generated HTML. [Ken Coar]
10234 Changes with Apache 1.2b6
10236 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
10238 *) Fix typo introduced in fix for potential infinite loop around
10239 accept() in child_main(). This change caused the rev to 1.2b6.
10240 1.2b5 was never a public beta.
10242 Changes with Apache 1.2b5
10244 *) Change KeepAlive semantics (On|Off instead of a number), add
10245 MaxKeepAliveRequests directive. [Alexei Kosut]
10247 *) Various NeXT compilation patches, as well as a change in
10248 regex/regcomp.c since that file also used a NEXT define.
10251 *) Allow * to terminate the end of a directory match in mod_dir.
10252 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
10254 *) Don't call can_exec() if suexec_enabled. Calling this requires
10255 scripts executed by the suexec wrapper to be world executable, which
10256 defeats one of the advantages of running the wrapper. [Randy Terbush]
10258 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
10261 *) Migration from sprintf() to snprintf() to avoid buffer
10262 overflows. [Marc Slemko]
10264 *) Provide portable snprintf() implementation (ap_snprintf)
10265 as well as *cvt family. [Jim Jagielski]
10267 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
10270 *) Remove mod_fastcgi.c from the distribution. This module appears
10271 to be maintained more through the Open Market channels and should
10272 continue to be easily available at http://www.fastcgi.com/
10274 *) Fixed bug in modules/Makefile that wouldn't allow building in more
10275 than one subdirectory (or cleaning, either). [Jeremy Laidman]
10277 *) mod_info assumed that the config files were relative to ServerRoot.
10280 *) CGI scripts called as an error document resulting from failed
10281 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
10283 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
10286 *) Properly check errno to prevent display of a directory index
10287 when server receives a long enough URL to confuse stat().
10290 *) Several security enhancements to suexec wrapper. It is _highly_
10291 recommended that previously installed versions of the wrapper
10292 be replaced with this version. [Randy Terbush, Jason Dour]
10294 - ~user execution now properly restricted to ~user's home
10295 directory and below.
10296 - execution restricted to UID/GID > 100
10297 - restrict passed environment to known variables
10298 - call setgid() before initgroups() (portability fix)
10299 - remove use of setenv() (portability fix)
10301 *) Add HTTP/1.0 response forcing. [Ben Laurie]
10303 *) Add access control via environment variables. [Ben Laurie]
10305 *) Add rflush() function. [Alexei Kosut]
10307 *) remove duplicate pcalloc() call in new_connection().
10309 *) Fix incorrect comparison which could allow number of children =
10310 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
10311 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
10313 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
10314 AIX PS/2, CONVEXOS. [Jim Jagielski]
10316 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
10317 It's more portable. [Martin Kraemer]
10319 *) Replace references to make in Makefile.tmpl with $(MAKE).
10322 *) Add ProxyBlock directive w/IP address caching. Add IP address
10323 caching to NoCache directive as well. ProxyBlock works with all
10324 handlers; NoCache now also works with FTP for anonymous logins.
10325 Still more code cleanup. [Chuck Murcko]
10327 *) Add "header parse" API hook [Ben Laurie]
10329 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
10331 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
10333 *) Correctly allow access and auth directives in <Files> sections in
10334 server config files. [Alexei Kosut]
10336 *) Fix bug with ServerPath that could cause certain files to be not
10337 found by the server. [Alexei Kosut]
10339 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
10340 double-quote from text and so that it properly checks for unsupported
10341 status codes using the new index_of_response interface. [Roy Fielding]
10343 *) Multiple fixes to the lingering_close code in order to avoid being
10344 interrupted by a stray timeout, to avoid lingering on a connection
10345 that has already been aborted or never really existed, to ensure that
10346 we stop lingering as soon as any error condition is received, and to
10347 prevent being stuck indefinitely if the read blocks. Also improves
10348 reporting of error conditions. [Marc Slemko and Roy Fielding]
10350 *) Fixed initialization of parameter structure for sigaction.
10351 [mgyger@itr.ch, Adrian Filipi-Martin]
10353 *) Fixed reinitializing the parameters before each call to accept and
10354 select, and removed potential for infinite loop in accept.
10355 [Roy Fielding, after useful PR from adrian@virginia.edu]
10357 *) Fixed condition where, if a child fails to fork, the scoreboard would
10358 continue to say SERVER_STARTING forever. Eventually, the main process
10359 would refuse to start new children because count_idle_servers() will
10360 count those SERVER_STARTING entries and will always report that there
10361 are enough idle servers. [Phillip Vandry]
10363 *) Fixed bug in bcwrite regarding failure to account for partial writes.
10364 Avoided calling bflush() when the client is pipelining requests.
10365 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
10367 *) Added description of "." mode in server-status [Jim Jagielski]
10369 Changes with Apache 1.2b4
10371 *) Fix possible race condition in accept_mutex_init() that
10372 could leave a small security hole open allowing files to be
10373 overwritten in cases where the server UID has write permissions.
10376 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
10378 *) Fix portablity problem in util_script where ARG_MAX may not be
10379 defined for some systems.
10381 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
10384 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
10385 style magic #! token for better script portability. [Garey Smiley]
10387 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
10388 execution for ~userdir CGI. [Jason Dour]
10390 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
10392 *) Fix month off by one in suexec wrapper logging.
10394 Changes with Apache 1.2b3:
10396 *) Fix error in mod_cgi which could cause resources not to be properly
10397 freed, or worse. [Dean Gaudet]
10399 *) Fix find_string() NULL pointer dereference. [Howard Fear]
10401 *) Add set_flag_slot() at the request of Dirk and others.
10404 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
10406 *) Add changes to improve the error message given for invalid
10407 ServerName parameters. [Dirk vanGulik]
10409 *) Add "Authoritative" directive for Auth modules that don't
10410 currently have it. This gives admin control to assign authoritative
10411 control to an authentication scheme and allow "fall through" for
10412 those authentication modules that aren't "Authoritative" thereby
10413 allowing multiple authentication mechanisms to be chained.
10416 *) Remove requirement for ResourceConfig/AccessConfig if not using
10417 the three config file layout. [Randy Terbush]
10419 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
10421 *) Changes to suexec wrapper to fix the following problems:
10422 1. symlinked homedirs will kill ~userdirs.
10423 2. initgroups() on Linux 2.0.x clobbers gr->grid.
10424 3. CGI command lines paramters problems
10425 4. pw-pwdir for "docroot check" still the httpd user's pw record.
10426 [Randy Terbush, Jason Dour]
10428 *) Change create_argv() to accept variable arguments. This fixes
10429 a problem where arguments were not getting passed to the CGI via
10430 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
10432 *) Collapse multiple slashes in path URLs to properly apply
10433 handlers defined by <Location>. [Alexei Kosut]
10435 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
10437 *) Improve the accuracy of request duration timings by setting
10438 r->request_time in read_request_line() instead of read_request().
10441 *) Reset timeout while reading via get_client_block() in mod_cgi.c
10442 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
10444 *) Add the ability to pass different Makefile.tmpl files to Configure
10445 using the -make flag. [Rob Hartill]
10447 *) Fix coredump triggered when sending a SIGHUP to the server caused
10448 by an assertion failure, in turn caused by an uninitialised field in a
10452 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
10453 PATH_INFO from previous versions of Apache (in certain situations,
10454 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
10455 [later removed in 1.2b11]
10457 *) Add rwrite() function to API to allow for sending strings of
10458 arbitrary length. [Doug MacEachern]
10460 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
10462 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
10463 NeXT. [Jim Jagielski]
10465 *) Removed recent modification to promote the status code on internal
10466 redirects, since the correct fix was to change the default log format
10467 in mod_log_config so that it outputs the original status. [Rob Hartill]
10469 Changes with Apache 1.2b2:
10471 *) Update set_signals() to use sigaction() for setting handlers.
10472 This appears to fix a re-entrant problem in the seg_fault()
10473 bus_error() handlers. [Randy Terbush]
10475 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
10477 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
10479 *) proxy_http.c bugfixes: [Chuck Murcko]
10480 1) fixes possible NULL pointer reference w/NoCache
10481 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
10482 host would cache nothing if it was in the local domain,
10483 and the local domain was in the NoCache list)
10484 3) Adds Host: header when not available
10485 4) Some code cleanup and clarification
10487 *) mod_include.c bugfixes:
10488 1) Fixed an ommission that caused include variables to not
10489 be parsed in config errmsg directives [Howard Fear]
10490 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
10491 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
10492 4) Allow backslash-escaping to all quoted text
10493 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
10494 5) Pass variable to command line if not set in XSSI's env
10497 *) Fix infinite loop when processing Content-language lines in
10498 type-map files. [Alexei Kosut]
10500 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
10502 *) Fixed problem in set_[user|group] that prevented CGI execution
10503 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
10505 *) Added PORTING information file. [Jim Jagielski]
10507 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
10509 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
10511 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
10512 USE_FCNTL_SERIALIZED_ACCEPT was intended.
10514 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
10515 which caused problems of systems where socket s_addr is >32bits.
10517 *) Added comment to explain (r->chunked = 1) side-effect in
10518 http_protocol.c [Roy Fielding]
10520 *) Replaced use of index() in mod_expires.c with more appropriate
10521 and portable isdigit() test. [Ben Laurie]
10523 *) Updated Configure for ...
10524 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
10525 *-dg-dgux* (bad pattern match)
10526 QNX (DEF_WANTHSREGEX=yes)
10527 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
10529 *-unixware211 (new)
10530 and added some user diagnostic info. [Ben Laurie]
10532 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
10533 for better portability. [Jim Jagielski]
10535 *) Updated helpers/GuessOS for ...
10536 SCO 5 (recognize minor releases)
10537 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
10538 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
10539 IRIX64 (-sgi-irix64)
10540 ULTRIX (-unknown-ultrix)
10541 SINIX (-whatever-sysv4)
10542 NCR Unix (-ncr-sysv4)
10543 and fixed something in helpers/PrintPath [Ben Laurie]
10545 Changes with Apache 1.2b1
10547 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
10549 Changes with Apache 1.1.1
10551 *) Fixed bug where Cookie module would make two entries in the
10552 logfile for each access [Mark Cox]
10554 *) Fixed bug where Redirect in .htaccess files would cause memory
10555 leak. [Nathan Neulinger]
10557 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
10559 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
10561 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
10563 Changes with Apache 1.1.0
10565 *) Bring NeXT support up to date. [Takaaki Matsumoto]
10567 *) Bring QNX support up to date. [Ben Laurie]
10569 *) Make virtual hosts default to main server keepalive parameters.
10570 [Alexei Kosut, Ben Laurie]
10572 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
10574 *) Fix missing address family for connect, also remove unreachable statement
10575 in mod_proxy. [Ben Laurie]
10577 *) mod_env now turned on by default in Configuration.tmpl.
10579 *) Bugs which were fixed:
10580 a) yet more mod_proxy bugs [Ben Laurie]
10581 b) CGI works again with inetd [Alexei Kosut]
10582 c) Leading colons were stripped from passwords [osm@interguide.com]
10583 d) Another fix to multi-method Limit problem [jk@tools.de]
10585 Changes with Apache 1.1b4
10587 *) r->bytes_sent variable restored. [Robert Thau]
10589 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
10591 *) More possibly unsecure programs removed from the support directory.
10593 *) More mod_auth_msql authentication improvements.
10595 *) VirtualHosts based on Host: headers no longer conflict with the
10598 *) OS/2 compatibility enhancements. [Gary Smiley]
10600 *) POST now allowed to directory index CGI scripts.
10602 *) Actions now work with files of the default type.
10604 *) Bugs which were fixed:
10605 a) more mod_proxy bugs
10606 b) early termination of inetd requests
10607 c) compile warnings on several systems
10608 d) problems when scripts stop reading output early
10610 Changes with Apache 1.1b3
10612 *) Much of cgi-bin and all of cgi-src has been removed, due to
10613 various security holes found and that we could no longer support
10616 *) The "Set-Cookie" header is now special-cased to not merge multiple
10617 instances, since certain popular browsers can not handle multiple
10618 Set-Cookie instructions in a single header. [Paul Sutton]
10620 *) rprintf() added to buffer code, occurrences of sprintf removed.
10623 *) CONNECT method for proxy module, which means tunneling SSL should work.
10624 (No crypto needed) Also a NoCache config directive.
10626 *) Several API additions: pstrndup(), table_unset() and get_token()
10627 functions now available to modules.
10629 *) mod_imap fixups, in particular Location: headers are now complete
10632 *) New "info" module which reports on installed module set through a
10633 special URL, a la mod_status.
10635 *) "ServerPath" directive added - allows for graceful transition
10636 for Host:-header-based virtual hosts.
10638 *) Anonymous authentication module improvements.
10640 *) MSQL authentication module improvements.
10642 *) Status module design improved - output now table-based. [Ben Laurie]
10644 *) htdigest utility included for use with digest authentication
10647 *) mod_negotiation: Accept values with wildcards to be treated with
10648 less priority than those without wildcards at the same quality
10649 value. [Alexei Kosut]
10651 *) Bugs which were fixed:
10652 a) numerous mod_proxy bugs
10653 b) CGI early-termination bug [Ben Laurie]
10654 c) Keepalives not working with virtual hosts
10655 d) RefererIgnore problems
10656 e) closing fd's twice in mod_include (causing core dumps on
10657 Linux and elsewhere).
10659 Changes with Apache 1.1b2
10662 a) core dumps in mod_digest
10663 b) truncated hostnames/ip address in the logs
10664 c) relative URL's in mod_imap map files
10666 Changes with Apache 1.1b1
10668 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
10670 Changes with Apache 1.0.3
10672 *) Internal redirects which occur in mod_dir.c now preserve the
10673 query portion of a request (the bit after the question mark).
10676 *) Escape active characters '<', '>' and '&' in html output in
10677 directory listings, error messages and redirection links.
10680 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
10682 *) Fix for POSIX compliance in waiting for processes in alloc.c.
10685 *) setsockopt no longer takes a const declared argument [Martijn Koster]
10687 *) Reset timeout timer after each successful fwrite() to the network.
10688 This patch adds a reset_timeout() procedure that is called by
10689 send_fd() to reset the timeout ever time data is written to the net.
10692 *) timeout() signal handler now checks for SIGPIPE and reports
10693 lost connections in a more user friendly way. [Rob Hartill]
10695 *) Location of the "scoreboard" file which used to live in /tmp is
10696 now configurable (for OSes that can't use mmap) via ScoreBoardFile
10697 which works similar to PidFile (in httpd.conf) [Rob Hartill]
10699 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
10701 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
10702 which caused a SEGV with cookies enabled
10704 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
10707 *) Log the UNIX textual error returned by some system calls, in
10708 particular errors from accept() [David Robinson]
10710 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
10712 Changes with Apache 1.0.2
10714 *) patch to get Apache compiled on UnixWare 2.x, recommended as
10715 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
10717 *) Fix get_basic_auth_pw() to set the auth_type of the request.
10720 *) past changes to http_config.c to only use the
10721 setrlimit function on systems defining RLIMIT_NOFILE
10722 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
10723 for SUNOS and prototypes the needed functions.
10725 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
10728 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
10730 *) Merge multiple headers from CGI scripts instead of taking last
10731 one. [David Robinson]
10733 *) Add support for SCO 5. [Ben Laurie]
10735 Changes with Apache 1.0.1
10737 *) Silence mod_log_referer and mod_log_agent if not configured
10740 *) Recursive includes can occur if the client supplies PATH_INFO data
10741 and the server provider uses relative links; as file.html
10742 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
10744 *) The replacement for initgroups() did not call {set,end}grent(). This
10745 had two implications: if anything else used getgrent(), then
10746 initgroups() would fail, and it was consuming a file descriptor.
10749 *) On heavily loaded servers it was possible for the scoreboard to get
10750 out of sync with reality, as a result of a race condition.
10751 The observed symptoms are far more Apaches running than should
10752 be, and heavy system loads, generally followed by catastrophic
10753 system failure. [Ben Laurie]
10755 *) Fix typo in license. [David Robinson]
10757 Changes with Apache 1.0.0 23 Nov 1995
10759 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
10761 Changes with Apache 0.8.16 05 Nov 1995
10763 *) New man page for 'httpd' added to support directory [David Robinson]
10765 *) .htgroup files can have more than one line giving members for a
10766 given group (each must have the group name in front), for NCSA
10767 back-compatibility [Robert Thau]
10769 *) Mutual exclusion around accept() is on by default for SVR4 systems
10770 generally, since they generally can't handle multiple processes in
10771 accept() on the same socket. This should cure flaky behavior on
10772 a lot of those systems. [David Robinson]
10774 *) AddType, AddEncoding, and AddLanguage directives take multiple
10775 extensions on a single command line [David Robinson]
10777 *) UserDir can be disabled for a given virtual host by saying
10778 "UserDir disabled" in the <VirtualHost> section --- it was a bug
10779 that this didn't work. [David Robinson]
10781 *) Compiles on QNX [Ben Laurie]
10783 *) Corrected parsing of ctime time format [David Robinson]
10785 *) httpd does a perror() before exiting if it can't log its pid
10786 to the PidFile, to make diagnosing the error a bit easier.
10789 *) <!--#include file="..."--> can no longer include files in the
10790 parent directory, for NCSA back-compatibility. [David Robinson]
10792 *) '~' is *not* escaped in URIs generated for directory listings
10795 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
10797 *) Fixed bug involving handling URIs with escaped %-characters
10798 in redirects [David Robinson]
10800 Changes with Apache 0.8.15 14 Oct 1995
10802 *) Switched to new, simpler license
10804 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
10806 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
10808 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
10810 *) Correctly handles internal redirects to files with names containing '%'
10813 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
10815 *) Use geteuid() rather than getuid() to see if we have root privilege,
10816 so that server correctly resets privilege if run setuid root. [Andrew
10819 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
10822 *) Fix relative URLs in imagemap files [Randy Terbush]
10824 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
10827 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
10828 entries all name the same one. [David Robinson]
10830 *) Fix directory listings with filenames containing unusual characters
10833 *) Better URI-escaping for generated URIs in directories with filenames
10834 containing unusual characters [Ben Laurie]
10836 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
10838 *) Unblock alarms on error return from spawn_child() [David Robinson]
10840 *) Sample Config files have extra note for SCO users [Ben Laurie]
10842 *) Configuration has note for HP-UX users [Rob Hartill]
10844 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
10846 *) Nuked bogus #define in httpd.h [David Robinson]
10848 *) Better test for whether a system has setrlimit() [David Robinson]
10850 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
10852 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
10855 Changes with Apache 0.8.14 19 Sep 1995
10857 *) Compiles on SCO ODT 3.0 [Ben Laurie]
10859 *) AddDescription works (better) [Ben Laurie]
10861 *) Leaves an intelligible error diagnostic when it can't set group
10862 privileges on standalone startup [Andrew Wilson]
10864 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
10865 that machine, which claims to be BSD but does not support RLIMIT.
10868 *) gcc -Wall no longer complains about an unused variable when util.c
10869 is compiled with -DMINIMAL_DNS [Andrew Wilson]
10871 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
10873 Changes with Apache 0.8.13 07 Sep 1995
10875 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
10877 *) Have built-in imagemap code recognize & honor Point directive [James
10880 *) Generate cleaner directory listings in directories with a mix of
10881 long and short filenames [Rob Hartill]
10883 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
10885 *) Properly default ServerName for virtual servers [Robert Thau]
10887 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
10888 Paul Richards and a cast of thousands...]
10890 *) On self-identified BSD systems (we don't try to guess any more),
10891 allocate a few extra file descriptors per virtual host with setrlimit,
10892 if we can, to avoid running out. [Randy Terbush]
10894 *) Write 22-character lock file name into buffer with enough space
10895 on startup [Konstantin Olchanski]
10897 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
10900 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
10902 *) Suppress -Wall warning by initializing variable in negotiation code
10903 [Tobias Weingartner]
10905 Changes with Apache 0.8.12 31 Aug 1995
10907 *) Doesn't pause three seconds after including a CGI script which is
10908 too slow to die off (this is done by not even trying to kill off
10909 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
10910 after the entire document has been processed). [Robert Thau]
10912 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
10914 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
10916 *) Allows .htaccess files to override <Directory> sections naming the
10917 same directory [David Robinson]
10919 *) Removed an efficiency hack in sub_req_lookup_uri which was
10920 causing certain extremely marginal cases (e.g., ScriptAlias of a
10921 *particular* index.html file) to fail. [David Robinson]
10923 *) Doesn't log an error when the requested URI requires
10924 authentication, but no auth header line was supplied by the
10925 client; this is a normal condition (the client doesn't no auth is
10926 needed here yet). [Robert Thau]
10928 *) Behaves more sanely when the name server loses its mind [Sean Welch]
10930 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
10932 *) RFC931 code no longer passes out name of prior clients on current
10933 requests if the current request came from a server that doesn't
10934 do RFC931. [David Robinson]
10936 *) Configuration script accepts "Module" lines with trailing whitespace.
10939 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
10941 *) Cleaned up comments in mod_cgi.c [Robert Thau]
10943 Changes with Apache 0.8.11 24 Aug 1995
10945 *) Wildcard <Directory> specifications work. [Robert Thau]
10947 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
10949 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
10950 the file being requested itself, in addition to the directories leading
10951 up to it. [Robert Thau]
10953 *) Logs access failures due to symlink checks or invalid client address
10954 in the error log [Roy Fielding, Robert Thau]
10956 *) Symlink checks deal correctly with systems where lstat of
10957 "/path/to/some/link/" follows the link. [Thau, Fielding]
10959 *) Doesn't reset DirectoryIndex to 'index.html' when
10960 other directory options are set in a .htaccess file. [Robert Thau]
10962 *) Clarified init code and nuked bogus warning in mod_access.c
10963 [Florent Guillaume]
10965 *) Corrected several directives in sample srm.conf
10966 --- includes corrections to directory indexing icon-related directives
10967 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
10968 icons for encodings right, and turning on AddEncoding by default).
10971 *) Corrected descriptions of args to AddIcon and AddAlt in command table
10974 *) INSTALL & README mention "contributed modules" directory [Brian
10977 *) Fixed English in the license language... "for for" --> "for".
10980 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
10981 mod_alias.c, merging it almost completely with handling of Alias, and
10982 adding a 'notes' field to the request_rec which allows the CGI module
10983 to discover whether the Alias module has put this request through
10984 ScriptAlias (which it needs to know for back-compatibility, as the old
10985 NCSA code did not check Options ExecCGI in ScriptAlias directories).
10988 Changes with Apache 0.8.10 18 Aug 1995
10990 *) AllowOverride applies to the named directory, and not just
10991 subdirectories. [David Robinson]
10993 *) Do locking for accept() exclusion (on systems that need it)
10994 using a special file created for the purpose in /usr/tmp, and
10995 not the error log; using the error log causes real problems
10996 if it's NFS-mounted; this is known to be the cause of a whole
10997 lot of "server hang" problems with Solaris. [David Robinson;
10998 thanks to Merten Schumann for help diagnosing the problem].
11000 Changes with Apache 0.8.9 12 Aug 1995
11002 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
11004 *) Nested includes see environment variables of the including document,
11005 for NCSA bug-compatibility (some sites have standard footer includes
11006 which try to print out the last-modified date). [Eric Hagberg/Robert
11009 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
11010 URI as a CGI script, even if it would have been treated as something
11011 else if requested directly, for NCSA back-compatibility. (Note that
11012 this means that people who know the name of the script can see the
11013 code just by asking for it). [Robert Thau]
11015 *) New version of dbmmanage script included in support directory as
11018 *) Check if scoreboard file couldn't be opened, and say so, rather
11019 then going insane [David Robinson]
11021 *) POST to CGI works on A/UX [Jim Jagielski]
11023 *) AddIcon and AddAlt commands work properly [Rob Hartill]
11025 *) NCSA server push works properly --- the Arena bug compatibility
11026 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
11027 if you still want the workaround). [Rob Hartill]
11029 *) If client didn't submit any Accept-encodings, ignore encodings in
11030 content negotiation. (NB this will all have to be reworked anyway
11031 for the new HTTP draft). [Florent Guillaume]
11033 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
11035 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
11037 *) Give Redirect priority over Alias, for NCSA bug compatibility
11040 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
11041 paralleling earlier bug fix for CGI [David Robinson]
11043 *) If DBM auth is improperly configured, report a server error and don't
11046 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
11047 it seems to work well enough without it (even in a 10 hits/sec
11048 workout), and the overhead for the locking under A/UX is
11049 alarmingly high (though it is very low on other systems).
11050 [Eric Hagberg, Jim Jagielski]
11052 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
11054 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
11055 Behlendorf/Eric Hagberg]
11057 *) More improvements to default Configuration for A/UX [Jim Jagielski]
11059 *) Compiles clean on NEXT [Rob Hartill]
11061 *) Compiles clean on SGI [Robert Thau]
11063 Changes with Apache 0.8.8 08 Aug 1995
11065 *) SunOS library prototypes now never included unless explicitly
11066 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
11067 people using GNU libc on SunOS are screwed by prototypes for the
11070 (Those who wish to compile clean with gcc -Wall on a standard
11071 SunOS setup need the prototypes, and may obtain them using
11072 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
11073 with nonstandard libraries are presumably competent to make their
11076 *) Strips trailing '/' characters off both args to the Alias command,
11077 to make 'Alias /foo/ /bar/' work.
11079 Changes with Apache 0.8.7 03 Aug 1995
11081 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
11082 [reported by David Robinson]
11084 *) Compiles clean on OSF/1 [David Robinson]
11086 *) Added some of the more recent significant changes (AddLanguage stuff,
11087 experimental LogFormat support) to CHANGES file in distribution root
11090 Changes with Apache 0.8.6 02 Aug 1995
11092 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
11093 (If you actually wanted a conditional GET which bypassed the cache, you
11094 couldn't get it). [Reported by Roy Fielding]
11096 *) Properly terminate headers on '304 Not Modified' replies to conditional
11097 GETs --- no browser we can find cares much, but the CERN proxy chokes.
11098 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
11100 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
11102 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
11103 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
11104 and older versions don't set the __SUNPRO_C preprocessor variable). On
11105 all other systems, these are never used anyway. [Reported by Mark Cox].
11107 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
11109 Changes with Apache 0.8.5 01 Aug 1995
11111 *) Added last-minute configurable log experiment, as optional module
11113 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
11114 properly. (One-line fix to http_protocol.c).
11116 *) Work around bogus behavior when reloading from Netscape.
11117 It's Netscape's bug --- for some reason they expect a request with
11118 If-modified-since: to not function as a conditional GET if it also
11119 comes with Pragma: no-cache, which is way out of line with the HTTP
11120 spec (according to Roy Fielding, the redactor).
11122 *) Added parameter to set maximum number of server processes.
11124 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
11127 *) IdentityCheck bugfix [Chuck Murcko].
11129 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
11131 *) More sample config file corrections; add extension to AddType for
11132 *.asis, move AddType generic description to its proper place, and
11133 fix miscellaneous typos. [ Alexei Kosut ]
11135 *) Deleted the *other* reference to the regents from the Berkeley
11136 legal disclaimer (everyplace).
11138 *) Nuked Shambhala name from src/README; had already cleaned it out
11139 of everywhere else.
11141 Changes with Apache 0.8.4
11143 *) Changes to server-pool management parms --- renamed current
11144 StartServers to MinSpareServers, created separate StartServers
11145 parameter which means what it says, and renamed MaxServers to
11146 MaxSpareServers (though the old name still works, for NCSA 1.4
11147 back-compatibility). The old names were generally regarded as
11148 too confusing. Also altered "docs" in sample config files.
11150 *) More improvements to default config files ---
11151 sample directives (commented out) for XBitHack, BindAddress,
11152 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
11153 defaults, AddTypes for send-as-is and imagemap magic types, and
11154 improvements to samples for DirectoryIndex [Alexei Kosut]
11156 *) Yet more improvements to default config files --- changes to
11157 Alexei's sample AddLanguage directives, and sample LanguagePriority
11158 [ Florent Guillaume ]
11160 *) Set config file locations properly if not set in httpd.conf
11163 *) Don't escape URIs in internal redirects multiple times; don't
11164 do that when translating PATH_INFO to PATH_TRANSLATED either.
11167 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
11169 Changes with Apache 0.8.3
11171 *) Edited distribution README to *briefly* summarize installation
11172 procedures, and give a pointer to the INSTALL file in the src/
11175 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
11176 recent NCSA distributions.
11178 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
11179 exist for the same directory, use both and don't segfault. [Reported
11182 *) Proper makefile dependencies [David Robinson]
11184 *) Note (re)starts in error log --- reported by Rob Hartill.
11186 *) Only call no2slash() after get_path_info() has been done, to
11187 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
11188 reported by Andrew Wilson, though this one is probably a real bug]
11190 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
11191 dump core when Referer is not supplied. [Randy Terbush]
11193 *) Lightly edited sample config files to refer people to our documentation
11194 instead of NCSA's, and to list Rob McCool as *original* author (also
11195 deleted his old, and no doubt non-functional email address). Would be
11196 nice to have examples of new features...
11198 Changes with Apache 0.8.2 19 Jul 1995
11200 *) Added AddLanuage code [Florent Guillaume]
11202 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
11204 *) All sorts of problems when MultiViews finds a directory. It would
11205 be nice if mod_dir.c was robust enough to handle that, but for now,
11206 just punt. [reported by Brian Behlendorf]
11208 *) Wait for all children on restart, to make sure that the old socket
11209 is gone and we can reopen it. [reported by Randy Terbush]
11211 *) Imagemap module is enabled in default Configuration
11213 *) RefererLog and UserAgentLog modules properly default the logfile
11216 *) Mark Cox's mod_cookies added to the distribution as an optional
11217 module (commented out in the default Configuration, and noted as
11218 an experiment, along with mod_dld). [Mark Cox]
11220 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
11222 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
11224 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
11226 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
11229 Changes with Apache 0.8.1
11231 *) New imagemap module [Randy Terbush]
11233 *) Replacement referer log module with NCSA-compatible RefererIgnore
11234 [Matthew Gray again]
11236 *) Don't mung directory listings with very long filenames.
11237 [Florent Guillaume]
11239 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
11241 *) New config script. See INSTALL for info. [Robert Thau]
11243 *) Scoreboard mechanism for regulating the number of extant server
11244 processes. MaxServers and StartServers defaults are the same as
11245 for NCSA, but the meanings are slightly different. (Actually,
11246 I should probably lower the MaxServers default to 10).
11248 Before asking for a new connection, each server process checks
11249 the number of other servers which are also waiting for a
11250 connection. If there are more than MaxServers, it quietly dies
11251 off. Conversely, every second, the root, or caretaker, process
11252 looks to see how many servers are waiting for a new connection;
11253 if there are fewer than StartServers, it starts a new one. This
11254 does not depend on the number of server processes already extant.
11255 The accounting is arranged through a "scoreboard" file, named
11256 /tmp/htstatus.*, on which each process has an independent file
11257 descriptor (they need to seek without interference).
11259 The end effect is that MaxServers is the maximum number of
11260 servers on an *inactive* server machine, but more will be forked
11261 off to handle unusually heavy loads (or unusually slow clients);
11262 these will die off when they are no longer needed --- without
11263 reverting to the overhead of full forking operation. There is a
11264 hard maximum of 150 server processes compiled in, largely to
11265 avoid forking out of control and dragging the machine down.
11266 (This is arguably too high).
11268 In my server endurance tests, this mechanism did not appear to
11269 impose any significant overhead, even after I forced it to put the
11270 scoreboard file on a normal filesystem (which might have more
11271 overhead than tmpfs). [Robert Thau]
11273 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
11276 *) Read .htaccess files even in directory with <Directory> section.
11277 (Former incompatibility noted on mailing list, now fixed). [Robert
11280 *) "HEAD /" gives the client a "Bad Request" error message, rather
11281 than trying to send no body *and* no headers. [Cliff Skolnick].
11283 *) Don't produce double error reports for some very obscure cases
11284 mainly involving auth configuration (the "all modules decline to
11285 handle" case which is a sure sign of a server bug in most cases,
11286 but also happens when authentication is badly misconfigured).
11289 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
11290 it's *for*, and this sort of thing really shouldn't be cluttering
11291 up the Makefile). [Robert Thau]
11293 *) Incidental code cleanups in http_main.c --- stop dragging
11294 sa_client around; just declare it where used. [Robert Thau]
11296 *) Another acc-related fix. (It doesn't like const char
11297 in some places...). [Mark Cox]
11299 Changes with Shambhala 0.6.1 13 Jul 1995
11301 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
11302 Also, fixed auth typo in http_protocol.c unmasked by this fix.
11304 *) Compiles clean with acc on SunOS [Paul Sutton]
11306 *) Reordered modules in modules.c so that Redirect takes priority
11307 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
11308 believe it or not, he has an actual site with a ScriptAlias and
11309 a Redirect declared for the *exact same directory*. Even *my*
11310 compatibility fetish wouldn't motivate me to fix this if the fix
11311 required any effort, but it doesn't, so what the hey.
11313 *) Fixed to properly default several server_rec fields for virtual
11314 servers from the corresponding fields in the main server_rec.
11315 [Cliff Skolnick --- 'port' was a particular irritant].
11317 *) No longer kills off nph- child processes before they are
11318 finished sending output. [Matthew Gray]
11320 Changes with Shambhala 0.6.0 10 Jul 1995
11322 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
11323 the connection to the client in an "aborted" state, but otherwise
11324 allow whatever handlers are running to clean up. hard_timeout()s
11325 abort the request in progress completely; anything not tied to some
11326 resource pool cleanup will leak. They're still around because I
11327 haven't yet come up with a more elegant way of handling
11328 timeouts when talking to something that isn't the client. The
11329 default_handler and the dir_handler now use soft timeouts, largely
11330 so I can test the feature. [Robert Thau]
11332 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
11333 the case of log handlers dying prematurely is probably handled VERY
11334 gracelessly at this point, and if the logger stops reading input,
11335 the server will hang. (It is known to correctly restart the
11336 logging process on server restart; this is (should be!) going through
11337 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
11338 script). [Robert Thau]
11340 *) asis files supported (new module). [Robert Thau]
11342 *) IdentityCheck code is compiled in, but has not been tested. (I
11343 don't know anyone who runs identd). [Robert Thau]
11345 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
11346 came in with the request, for NCSA bug-compatibility. [Robert Thau]
11348 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
11350 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
11351 as timeouts are not in scope. [Robert Thau]
11353 *) quoted-string args in config files now handled correctly (doesn't drop
11354 the last character). [Robert Thau; reported by Randy Terbush]
11356 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
11357 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
11359 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
11360 default default type); the former default default behavior when all
11361 type-checkers defaulted had been a core dump. [Paul Sutton]
11363 *) Copy filenames out of the struct dirent when indexing
11364 directories. (On Linux, readdir() returns a pointer to the same
11365 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
11367 Changes with Shambhala 0.5.3 [not released]
11369 *) Default response handler notes "file not found" in the error log,
11370 if the file was not found. [Cliff Skolnick].
11372 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
11373 code no longer sets up bogus PATH_INFO which fakes out the directory
11374 handler). [Cliff Skolnick]
11376 Changes with Shambhala 0.5.2 06 Jul 1995
11378 *) Changes to http_main.c --- root server no longer plays silly
11379 games with SIGCHLD, and so now detects and replaces dying
11380 children. Child processes just die on SIGTERM, without taking
11381 the whole process group with them. Potential problem --- if any
11382 child process refuses to die, we hang in restart.
11383 MaxRequestsPerChild may still not work, but it certainly works
11384 better than it did before this! [Robert Thau]
11386 *) mod_dir.c bug fixes: ReadmeName and HeaderName
11387 work (or work better, at least); over-long description lines
11388 properly terminated. [Mark Cox]
11390 *) http_request.c now calls unescape_url() more places where it
11391 should [Paul Sutton].
11393 *) More directory handling bugs (reported by Cox)
11394 Parent Directory link is now set correctly. [Robert Thau]
11396 Changes with Shambhala 0.5.1 04 Jul 1995
11398 *) Generalized cleanup interface in alloc.c --- any function can be
11399 registered with alloc.c as a cleanup for a resource pool;
11400 tracking of files and file descriptors has been reimplemented in
11401 terms of this interface, so I can give it some sort of a test.
11404 *) More changes in alloc.c --- new cleanup_for_exec() function,
11405 which tracks down and closes all file descriptors which have been
11406 registered with the alloc.c machinery before the server exec()s a
11407 child process for CGI or <!--#exec-->. CGI children now get
11408 started with exactly three file descriptors open. Hopefully,
11409 this cures the problem Rob H. was having with overly persistent
11410 CGI connections. [Robert Thau]
11412 *) Mutual exclusion around the accept() in child_main() --- this is
11413 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
11414 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
11415 This uses fcntl(F_SETLK,...) on the error log descriptor because
11416 flock() on that descriptor won't work on systems which have BSD
11417 flock() semantics, including (I think) Linux 1.3 and Solaris.
11419 This does work on SunOS (when the server is idle, only one
11420 process in the pool is waiting on accept()); it *ought* to work
11421 on the other systems. [Robert Thau]
11423 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
11425 *) sizeof(*sa_client) bugfix from [Rob Hartill]
11427 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
11429 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
11430 be unnecessary if I go to the revised timeout-handling scheme).
11433 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
11434 string) even if none came in with the request. [Robert Thau]
11436 *) CHANGES file added to distribution ;-).
11438 Changes with Shambhala 0.4.5
11440 *) mod_dld --- early dynamic loading support [rst]
11441 *) Add wildcard content handlers for XBITHACK; default_hander now
11442 invoked with that mechanism (as a handler hanging off mod_core) [rst]
11443 *) XBITHACK supported as a wildcard content-handler, and
11444 configurable at run-time (not just at compile time, as in the
11445 "patchy server" releases) [rst]
11447 Changes with Shambhala 0.4.4 30 Jun 1995
11449 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
11450 *) Handle Addtype x/y .z [rst, reported by Cox]
11452 Changes with Shambhala 0.4.3
11454 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
11455 synonymous [rst, terbush]
11457 Changes with Shambhala 0.4.1 28 Jun 1995
11459 *) First-cut virtual host implementation; some refit in the config
11460 reading code, and log management, was necessary to support this [rst]
11461 *) Sub-pool machinery, originally added to avoid excessive storage
11462 allocation on listings of large directories (which turned out to
11463 be the problem that the 0.3 storage accounting was added to
11464 find). Subrequests and mod_dir changed to use subpools. [rst]
11465 *) More memory debugging --- free list consistency checks. [rst]
11466 *) Added err_headers to request_rec, with support elsewhere [rst]
11467 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
11469 Changes with Shambhala 0.3 19 Jun 1995
11471 *) Switch ONE_PROCESS to a runtime command-line option (-X)
11472 *) Don't compile in mod_ai_backcompat by default
11473 *) Switch name of server from Apache to Shambhala in Makefile
11474 *) Add some accounting routines to track memory usage in the pools,
11477 Changes with Shambhala 0.2
11479 *) Set DOCUMENT_ROOT CGI variable
11480 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
11481 *) Add critical section protection to handling of cleanup structures
11483 *) Significant code reorg within the server core to group related
11484 functions together [rst]
11485 *) Correctly handle clients that hang up before sending any request
11487 *) Replace dying child processes. [rst]
11489 Changes with Shambhala 0.1 12 Jun 1995
11491 Major rewrite of the pre-existing "patchy server" codebase, by
11492 Robert Thau (rst). Significant portions of the server code, such
11493 as configuration-file handling and HTTP authentication support,
11494 were ripped out and rewritten from scratch. Code that was not
11495 completely rewritten was significantly altered.
11497 Major changes with this release include:
11499 *) Introduction of the module API; in request handling, the central
11500 machinery just dispatches to various modules, which actually do
11501 most of the work. Configuration handling is similar --- modules
11502 declare their own commands, and the central machinery just
11503 dispatches to them.
11505 API features from shambhala/0.1 were substantially unchanged in
11506 Apache 1.0 and 1.1. (1.0 API features not yet present in this
11507 release, such as wildcard handlers and subpools, were added in
11508 subsequent Shambhala releases, and were also generally rst's
11511 *) This release included the following modules:
11513 mod_access (access control --- allow and deny directives),
11514 mod_alias (Alias and Redirect commands),
11515 mod_auth (straight HTTP authentication, based on flat-files)
11516 mod_auth_dbm (same, with dbm files)
11517 mod_cgi (CGI scripts and, in this release, ScriptAlias)
11518 mod_common_log (CLF access logs; later renamed mod_log_common)
11519 mod_dir (directory indexing)
11520 mod_include (server-side includes)
11521 mod_mime (AddType directives)
11522 mod_negotiation (content negotiation)
11523 mod_userdir (support for users' public_html directories)
11525 It also included a mod_ai_backcompat, which was a private hack
11526 for back-compatibility with rst's own AI-lab servers.
11528 All of these modules were substantially complete, and functional
11529 or nearly so (a few, which implemented features not in use at
11530 Thau's site, required patches of a few lines).
11532 *) sub-request machinery, to allow modules to determine how other
11533 modules would assign MIME types to a given file, or optionally
11534 serve its content (this is heavily used by mod_dir, mod_include
11535 and mod_negotiation).
11537 *) Resource pool system for keeping track of memory allocated and
11538 files opened in service of a particular request. Much of the
11539 code in the modules (when they weren't rewrites) was adjusted to
11540 replace a pervasive convention of using fixed-size buffers on
11541 the stack with an equally pervasive convention of using memory
11542 allocated with palloc().
11544 *) Reorganization of data structures associated with a given
11545 request to eliminate use of global variables and the troublesome
11546 unmunge_name function (used in NCSA and early Apache releases to
11547 attempt to determine the URI which mapped to a given filename
11548 --- a difficult proposition, given that it is easy to produce
11549 setups in which multiple URIs map to the same file).
11551 *) Source files renamed and rearranged
11553 *) Very simple pre-forking behavior --- parent process forked off a
11554 fixed number of children, and then just waited for SIGHUP.
11556 *) Other more minor changes too numerous to list.
11558 This release included modified versions of a lot of code from the
11559 Apache 0.6.4 public release, plus an early pre-forking patch
11560 codeveloped by Robert Thau and Rob Hartill.
11562 Changes with Apache 0.7.3 20 Jun 1995
11564 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
11565 were incorporated by Rob Hartill on the main branch while Robert Thau
11566 worked on the Shambhala rewrite above. Most were merged into the
11567 Shambala architecture after Apache 0.8.0.
11569 Changes with Apache 0.6.4 13 May 1995
11571 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
11574 Changes with Apache 0.5.1 10 Apr 1995
11576 Changes with Apache 0.4 02 Apr 1995
11578 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
11581 Changes with Apache 0.3 24 Mar 1995
11583 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
11586 Changes with Apache 0.2 18 Mar 1995
11588 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
11589 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
11590 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
