1 Changes with Apache 2.0.30-dev
2 *) More performance tweaks to the BNDM string-search algorithm
3 used to find "<!--#" tokens in mod_include [Brian Pane]
5 *) Miscellaneous small performance fixes: optimized away various
6 string copy operations and removed large temp buffers from
9 *) Fixed startup segfault that occurred when a VirtualHost
10 directive had a port but no address [Brian Pane]
12 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
14 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
15 if oslevel < WINNT. This should fix several problems reported
16 Against 2.0.28 on Windows 98 [Bill Stoddard]
18 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
19 to fail. [Bill Stoddard]
21 *) Change core code to allow an MPM to set hard thread/server
22 limits at startup. prefork, worker, and perchild MPMs now have
23 directives to set these limits. [Jeff Trawick]
25 *) Win32: The async AcceptEx() event should be autoreset upon
26 successful completion of a wait (WaitForSingleObject). This
27 eliminates a number of spurious
28 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
31 *) Move any load library path environment variables out of
32 apachectl and into a separate environment variable file which
33 can be more easily tailored by the admin. The environment
34 variable file as built by Apache may have additional system-
35 specific settings. For example, on OS/390 we tailor the heap
36 settings to allow lots of threads. [Jeff Trawick]
38 *) Use the new APR pool code to reduce pool-related lock
39 contention in the worker MPM. [Sander Striker]
41 *) The POD no longer assumes the child is listening on 127.0.0.1
42 and now pulls the first hostname in the list of listeners to
43 perform the dummy connect on. This fixes a bug when the user
44 had configured the Listen directive for an IP other than
45 127.0.0.1. This would result in undead children and error
46 messages such as "Connection refused: connect to listener".
49 *) The worker MPM now respects the LockFile setting, needed to
50 avoid locking problems with NFS. [Jeff Trawick]
52 *) Fix segfault when worker MPM receives SIGHUP.
53 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
55 *) Fix bug that could potentially prevent the perchild MPM from
56 working with more than one vhost/uid. [Aaron Bannert]
58 *) Change make install and apxs -i processing of DSO modules to
59 perform special handling on platforms where libtool doesn't install
60 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
61 which prevented standard LoadModule statements from working.
64 *) Whenever mod_so is enabled (not just when there are DSOs for
65 our modules), do whatever special magic is required for compiling/
66 loading third-party modules. This allows third-party DSOs to
67 be used on an AIX build when there were no built-in modules
68 built as DSOs. (This should help on OS/390 and BeOS as well.)
71 *) Allow apxs to be used to build DSOs on AIX without requiring the
72 user to hard-code the list of import files. (This should help
73 on OS/390 and BeOS as well.) [Jeff Trawick]
75 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
76 PR 8563, 8919 [William Rowe]
78 *) Get binary builds working when libapr and libaprutil are built
81 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
82 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
83 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
85 *) Fix the handling of SSI directives in which the ">" of the
86 terminating "-->" is the last byte in a file [Brian Pane]
88 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
89 message that we had back in apache-1.3 and still have scattered
90 throughout our docs. [Aaron Bannert]
92 *) Prevent the Win32 port from continuing after encountering an
93 error in the command line args to apache. [William Rowe]
95 *) On a error in the proxy, make it write a line to the error log
98 Changes with Apache 2.0.29
100 *) Add buffering in core_output_filter to ensure that long
101 lists of small buckets don't cause small packet writes.
102 [Brian Pane, Ryan Bloom]
104 *) Fix the installation target to make sure that the manual is
105 installed in the correct location.
106 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
107 Gomez Henri <hgomez@slib.fr>]
109 *) Fix the cmd command for mod_include. When we are processing
110 a cmd command, we do not want to use the r->filename to set
111 the command name. The command comes from the SSI tag. To do this,
112 I added a variable to the function that builds the command line
113 in mod_cgi. This allows the include_cmd function to specify
114 the command line itself. [Ryan Bloom]
116 *) Change open_logs hook to return a value, allowing you
117 to flag a error while opening logs
118 [Ian Holsman, Doug MacEachern]
120 *) Change post_config hook to return a value, allowing you
121 to flag a error post config
122 [Ian Holsman, Jeff Trawick]
124 *) Allow SUEXEC_BIN (the path to the suexec binary that is
125 hard-coded into the server) to be specified to the configure
126 script by the --with-suexec-bin parameter. [Aaron Bannert]
128 *) Fix segv in worker MPM following accept on pipe-of-death
131 *) Add mod_deflate to experimental.
132 [Ian Holsman, Justin Erenkrantz]
134 *) Bail out at configure time if an invalid MPM was specified.
135 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
137 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
138 configured [John Sterling <sterling@covalent.net>]
140 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
142 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
144 *) Optimization for the BNDM string-search function in
145 mod_include. [Brian Pane]
147 *) Fixed the behavior of the XBitHack directive.
148 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
150 *) The threaded MPM for Unix has been removed. Use the worker
151 MPM instead. [various]
153 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
154 in logging the error from a failed DNS lookup. [Jeff Trawick]
156 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
159 *) Get mod_cgid killed when a MPM exits due to a fatal error.
162 *) Fix a file descriptor leak in mod_include. When we include a
163 file, we use a sub-request, but we didn't destroy the sub-request
164 immediately, instead we waited until the original request was
165 done. This patch closes the sub-request as soon as the data is
166 done being generated. [Brian Pane <bpane@pacbell.net>]
168 *) Allow modules that add sockets to the ap_listeners list to
169 define the function that should be used to accept on that
170 socket. Each MPM can define their own function to use for
171 the accept function with the MPM_ACCEPT_FUNC macro. This
172 also abstracts out all of the Unix accept error handling
173 logic, which has become out of synch across Unix MPMs.
176 *) Fix a bug which would cause the response headers to be omitted
177 when sending a negotiated ErrorDocument because the required
178 filters were attached to the wrong request_rec.
179 [John Sterling <sterling@covalent.net>]
181 *) Remove commas from the end of the macros that define
182 directives that are used by MPMs. Prior to this patch,
183 you would use these macros without commas, which was unlike
184 the macros for any other directives. Now, the caller provides
185 the comma rather than the macro providing it. This makes
186 the macros look more like the rest of the directives.
187 [Ryan Bloom and Cliff Woolley]
189 *) Add 'redirect-carefully' environment option to disable sending
190 redirects under special circumstances. This is helpful for
191 Microsoft's WebFolders when accessing a directory resource via
192 DAV methods. [Justin Erenkrantz]
194 *) Begin to abstract out the underlying transport layer.
195 The first step is to remove the socket from the conn_rec,
196 the server now lives in a context that is passed to the
197 core's input and output filters. This forces us to be very
198 careful when adding calls that use the socket directly,
199 because the socket isn't available in most locations.
202 *) Really reset the MaxClients value in worker and threaded
203 when the configured value is not a multiple of the number
204 of threads per child. We said we did previously but we
205 forgot to. [Jeff Trawick]
207 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
209 *) If shared modules are requested and mod_so is not available,
210 produce a fatal config-time error. [Justin Erenkrantz]
212 *) Improve http2env's performance by cutting the work it has to
213 do. [Brian Pane <bpane@pacbell.net>]
215 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
216 [Brian Pane <bpane@pacbell.net>]
218 Changes with Apache 2.0.28
220 *) Fix infinite loop in mod_cgid.c.
221 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
223 *) When no port is given in a "ServerName host" directive, the
224 server_rec->port is now set to zero, not 80. That allows for
225 run-time deduction of the correct server port (depending on
226 SSL/plain, and depending also on the current setting of
227 UseCanonicalName). This change makes redirections
228 work, even with https:// connections. As in Apache-1.3, the
229 connection's actual port number is never used, only the ServerName
230 setting or the client's Host: setting. Documentation updated
231 to reflect the change. [Martin Kraemer]
233 *) Add a '%{note-name}e' argument to mod-headers, which works in
234 the same way as mod_log_confg. [Ian Holsman]
236 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
237 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
238 MPMs. [Cliff Woolley]
240 *) Introduce htdbm, a user management utility for db/dbm authorization
241 databases. [Mladen Turk <mturk@mappingsoft.com>]
243 *) Optimize usage of strlen and strcat in ap_directory_walk.
244 [Brian Pane <bpane@pacbell.net>]
246 Changes with Apache 2.0.27
248 *) Introduce an Apache mod_ssl initial configuration template
249 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
251 *) Fixed a memory leak in the getline parsing code that could
252 be triggered by arbitrarily large header lines. Requests
253 from the core input filter for single lines are now limited
254 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
256 *) Fix a truncation bug in how we print the port on the Via: header.
257 The routine that prints the Via: header now takes a length for
258 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
260 *) Some syntax errors in mod_mime_magic's magic file can result
261 in a 500 error, which previously was unlogged. Now we log the
262 error. [Jeff Trawick]
264 *) Add the support/checkgid helper app, which checks the run-time
265 validity of group identifiers usable in the Group directive.
268 *) Various --enable-so options have been fixed: --enable-so is
269 treated as "static"; explicit --enable-so=shared issues an error;
270 and explicit --enable-so fails with error on systems without
271 APR_HAS_DSO. [Aaron Bannert]
273 *) Fix a segfault in the core input filter when the client socket
274 gets disconnected unexpectedly. [Cliff Woolley]
276 *) Fix the reporting for child processes that die. This removes
277 all of the non-portable W* macros from Apache.
278 [Jeff Trawick and Ryan Bloom]
280 *) Win32: Track and display "Parent Server Generation:" in
281 mod_status output. The generation will be bumped at
282 server graceful restart, when the child process exits
283 by hitting MaxRequestsPerChild or if the child
284 process exits abnormally. [Bill Stoddard]
286 *) Win32: Fix problem where MaxRequestsPerChild directive was
287 not being picked up in favor of the default. Enable
288 the parent to start up a new child process immediately upon
289 the old child starting shutdown.
292 *) Fix some bungling of the remote port in rfc1413.c so that
293 IdentityCheck retrieves the proper user id instead of failing
294 and thus always returning "nobody."
295 [Dick Streefland <Dick.Streefland@xs4all.nl>]
297 *) Introduced thread saftey for mod_rewrite's internal cache.
298 [Brian Pane <bpane@pacbell.net>]
300 *) Simplified mod_env's directives to behave as most directives are
301 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
302 directive following that UnsetEnv within the same container.
303 Also provides a runtime startup warning if a PassEnv configured
304 environment value is undefined. [William Rowe]
306 *) The worker MPM is now completely ported to APR's new lock API. It
307 uses native APR types for thread mutexes, cross-process mutexes,
308 and condition variables. [Aaron Bannert]
310 *) Sync up documentation to remove all references to the now deprecated
311 Port directive. [Justin Erenkrantz]
313 *) Moved all ldap modules from the core to httpd-ldap sub-project
316 *) Exit when we can't listen on any of the configured ports. This
317 is the same behavior as 1.3, and it avoids having the MPMs to
318 deal with bogus ap_listen_rec structures. [Jeff Trawick]
320 *) Cleanup the proxy code that creates a request to the origin
321 server. This change adds an optional hook, which allows modules
322 to gain control while the request is created if the proxy module
323 is loaded. The purpose of this hook is to allow modules to add
324 input and/or output filters to the request to the origin. While
325 I was at it, I made the core use this hook, so that proxy request
326 creation uses some of the code from the core. This can still be
327 greatly improved, but this is a good start. [Ryan Bloom]
329 Changes with Apache 2.0.26
331 *) Port the MaxClients changes from the worker MPM to the threaded
334 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
335 with the new input filtering system. [Justin Erenkrantz]
337 *) Introduce the MultiviewsMatch directive, to allow the operator
338 to be flexible in recognizing Handlers and Filters filename
339 extensions as part of the Multiviews matching logic, strict with
340 MultiviewsMatch NegotiatedOnly to accept only filename extentions
341 that designate negotiated parameters, (content type, charset, etc.)
342 or MultiviewsAll for the 1.3 behavior of matching any files, even
343 if they have unregistered extensions. [William Rowe]
345 *) Fixed the configure script to add a LoadModule directive to
346 the default httpd.conf for any module that was compiled
347 as a DSO. [Aaron Bannert <aaron@clove.org>]
349 *) rewrite mod_ssl input filtering to work with the new input filtering
350 system. [Justin Erenkrantz]
352 *) prefork: Don't segfault when we are able to listen on some but
353 not all of the configured ports. [Jeff Trawick]
355 *) Build mod_so even if no core modules are built shared.
356 [Aaron Bannert <aaron@clove.org>]
358 *) Introduce ap_directory_walk rewrite (with further optimizations
359 required) to adapt to the ap_process_request_internal() changes.
360 Optimized so subrequests and redirects now reuse previous section
361 merges, until we mismatch with the original directory_walk, and
362 precomputed r->finfo results will cause directory_walk to skip
363 the most expensive phases of the function. [William Rowe]
365 *) Allow ApacheMonitor to connect to and control Apache on other
366 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
368 *) Remove the Port directive. In it's place, the Listen directive
369 is now a required directive, which tells Apache what port to
370 listen on. The ServerName directive has also been extended
371 to accept an optional port. If the port is specified to the
372 ServerName, the server will report that port whenever it
373 reports the port that it is listening on. This change was
374 made to ease configuration errors that stem from having a Port
375 directive, and a Listen directive. In that situation, the server
376 would only listen to the port specified by the Listen command,
377 which caused a lot of confusion to users. [Ryan Bloom]
379 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
380 build, as loadable modules. [William Rowe]
382 *) Fix --enable-mods-shared processing. If most is specified,
383 then all modules that can be compiled as shared modules are.
384 [Aaron Bannert <aaron@clove.org>]
386 *) Update the mime.types file to map video/vnd.mpegurl to mxu
387 and add commonly used audio/x-mpegurl for m3u extensions.
388 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
390 *) Eliminate the depreciated r->content_language, in favor of the array
391 r->content_languages introduced many years ago. Module authors must
392 substantially overhaul their modules, so this needs to be upgraded
393 if the module still relied on backwards-brokeness. [William Rowe]
395 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
398 *) Rewrite the input filtering mechanisms to consolidate and reorganize
399 code. In short, core_input_filter does something now and
400 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
402 *) Update the Win32 build to re-absorb mod_proxy and family.
405 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
406 current SDK.) [William Rowe]
408 *) Some style changes to the code that does ProxyErrorOverride. Fixed
409 config merge behaviour. [Graham Leggett]
411 *) Allow support programs to be compiled against a static version
412 of libapr. This allows the smaller support programs to be
413 relocated. [Aaron Bannert <aaron@clove.org>]
415 *) Update the mime.types file to the registered media types as
416 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
418 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
419 number of clients that can connect at the same time, instead of
420 specifying the maximum number of child processes.
421 [Aaron Bannert <aaron@clove.org>]
423 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
424 be consistent with 1.3. [Justin Erenkrantz]
426 *) Cache apr_explode_localtime() value for 15 seconds.
427 [Brian Pane <bpane@pacbell.net>]
429 *) Fix mod_include to not return ETag or Last-Modified headers.
430 [Ian Holsman <ianh@cnet.com>]
432 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
434 *) Eliminate the wasteful run-time conversion of method names from strings
435 to numbers in places where the methods are known at compile time.
436 [Brian Pane <bpane@pacbell.net>]
438 *) Turn the worker MPM's queue into a LIFO. This may
439 improve cache-hit performance under some conditions.
440 [Aaron Bannert <aaron@clove.org>]
442 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
443 support it. [Justin Erenkrantz]
445 *) Cleanup the worker MPM. We no longer re-use transaction
446 pools. This incurs less overhead than shuffling the pools
447 around so that they can be re-used. Remove one of the
448 queue's condition variables. We just redefined the API to
449 state that you can't try to add more stuff than you allocated
450 segments for. [Aaron Bannert <aaron@clove.org>]
452 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
454 *) Fixed persistent connections when a request contains a body.
457 *) mod_dav uses a new API to speak to the backend provider for dead
458 property management. [Greg Stein]
460 *) Remove the Win32 script-processing exception from mod_cgi, and
461 roll build_command_line/build_argv_list into a unified, overrideable
462 ap_cgi_build_command optional function. [William Rowe]
464 *) Rewrite find_start_sequence to use a better search algorithm
465 to find the start tag. [Justin Erenkrantz]
467 *) Fix a seg fault in mod_include. When we are generating an
468 internal redirect, we must set r->uri to "", not a bogus
469 string, and not NULL. [Ryan Bloom]
471 *) Optimized location_walk, so subrequests, redirects and second passes
472 now reuse previous section merges on a <Location > by <Location >
473 basis, until we mismatch with the original location_walk.
476 *) Back out the 1.45 change to util_script.c. This change made
477 us set the environment variable REQUEST_URI to the redirected
478 URI, instead of the originally requested URI.
479 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
481 *) Make mod_include do lazy evaluation of potentially expensive to
482 compute variables. [Brian Pane <bpane@pacbell.net>]
484 *) Fix logging of bytes sent for HEAD requests. %b and %B should
485 log either - or 0, before this patch, they were both logging
486 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
488 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
489 than per character. [Brian Pane <bpane@pacbell.net>]
491 *) Normalize the primary request, redirects and sub-requests to
492 run the same ap_process_request_internal for consistency in
493 robustness, behavior and security. [William Rowe]
495 *) Fix a segfault with mod_include when r->path_info is not set
496 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
498 *) Add -X functionality back. This indicates to all MPMs and any other
499 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
501 *) Some initial support for the cygwin platform [prefork only].
502 This is not to be confused with support for the WinNT/Win32
503 platform, which is the recommended configuration for native
504 Win32 users. The cygwin platform support is recommended for
505 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
507 *) Changed syntax of Set{Input|Output}Filter. The list of filters
508 must be semicolon delimited (if more than one filter is given.)
509 The Set{Input|Output}Filter directive now overrides a parent
510 container's directive (e.g. SetInputFilter in <Directory /web/foo>
511 will override any SetInputFilter directive in <Directory /web>.)
512 This new syntax is more consistent with Add{Input|Output}Filter
513 directives defined in mod_mime. Also cures a bug in prior releases
514 where the Set{Input|Output}Filter directive would corrupt the
515 global configuration if the multiple directives were nested.
518 *) Cured what's ailed mime for quite some time. If an AddSomething
519 was given in the configuration (Language, Charset, Handler or
520 Encoding) Apache would set the content type as given by AddType,
521 but refused to check the mime.types file if AddType wasn't given
522 for that specific extension. Setting the AddHandler for .html
523 without setting the AddType text/html html would cause Apache to
524 use the default content type. [William Rowe]
526 *) Added some bulletproofing to memory allocation in the LDAP cache
527 code. [Graham Leggett]
529 Changes with Apache 2.0.25
531 *) Move the installed /manual directory out of the /htdocs/ tree, so
532 that it can be kept more independently from the remaining document
533 root. The "Alias /manual ..." already allowed for easy projection
534 into existing private document trees. [Martin Kraemer]
536 *) Add specified user attributes to the environment when using
537 mod_auth_ldap. This allows you to use mod_include to embed specified
538 user attributes in a page like so:
539 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
542 *) Fix a performance problem with the worker MPM. We now create
543 transaction pools once, and re-use them for each connection.
544 [Aaron Bannert <aaron@clove.org>]
546 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
547 of a 'handler' or 'filter', so that any filename extension that does
548 not contribute to the negotiated metadata can't be served without
549 an explicit request. E.g., if the .Z extension is associated with
550 an unzip filter, the user request somefile.Z.html, mod_negotiation
551 won't serve it. It can serve somefile.Z.html when somefile.Z is
552 requested, since the .Z extension is explictly requested, if the
553 .html extension is associated with ContentType text/html.
556 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
557 and corresponding AddOutputFilter syntax, to insert one or more
558 filters by mod_mime filename extension processing.
561 *) Fix a growing connection pool in core_output_filter() for
562 keepalive requests. [Jeff Trawick]
564 *) Moved split_and_pass_pretag_buckets back to being a
565 macro at Ryans's request. Removed the return from it
566 by setting and returning a return code instead. Updated
567 the code to check the return code from the macro and
568 do the right thing. [Paul J. Reder]
570 *) Fix a segfault when a numeric value was received for Host:.
573 *) Add a function ap_remove_input_filter. This is to match
574 up with ap_remove_output_filter. [Ryan Bloom]
576 *) Clean up location_walk, so that this step performs a minimum
577 amount of redundant effort (it must be run twice, but it will no
578 longer reparse all <Location > blocks when the request uri
579 hadn't changed.) [William Rowe]
581 *) Eliminate proxy: (and all other 'special') processing from the
582 ap_directory_walk() phase. Modules that want to use special
583 walk logic should refer to the mod_proxy map_to_location example,
584 with it's proxy_walk and proxysection implementation. This makes
585 either directory_walk flavor much more legible, since that phase
586 only runs against real <Directory > blocks.
589 *) Fix a security problem in mod_include which would allow
590 an SSI document to be passed to the client unparsed.
591 [Cliff Woolley, Brian Pane]
593 *) Introduce the map_to_storage hook, which allows modules to bypass
594 the directory_walk and file_walk for non-file requests. TRACE
595 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
596 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
599 *) Add the ability for mod_include to add the INCLUDES filter
600 if the file is configured for the server-parsed handler.
601 This makes the configuration for .shtml files much easier
602 to understand, and allows mod_include to honor Apache 1.3
603 config files. Based on Doug MacEachern's patch to PHP
604 to do the same thing. [Ryan Bloom]
606 *) force OpenSSL to ignore process local-caching and to always
607 get/set/delete sessions using mod_ssl's callbacks
608 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
609 Geoff Thorpe <geoff@geoffthorpe.net>]
611 *) Make the worker MPM shutdown and restart cleanly. This also
612 cleans up some race conditions, and gets the worker using
613 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
615 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
617 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
619 *) Fix for mod_include. Ryan's patch to check error
620 codes put a return in the wrong place. Also, the
621 include handler return code wasn't being checked.
622 I don't like macros with returns, so I converted
623 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
624 [Paul J. Reder <rederpj@raleigh.ibm.com>]
626 *) fix segv in mod_mime if no AddTypes are configured
627 [John Sterling <sterling@covalent.net>]
629 *) Enable ssl client authentication at SSL_accept time
630 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
632 *) Fix a segfault in mod_include when the original request has no
633 associated filename (e.g., we're filtering the error document for
634 a bad URI). [Jeff Trawick]
636 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
638 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
639 of httpd is started and shuts down due to socket conflict. Moving the
640 call to ap_log_pid solves the problem.
642 *) Changed the late-1.3 log_config substitution %c to %X, to log the
643 status of the closed connection, as it conflicts with the far more
644 common, historical ssl logging directive %...{var}c. [William Rowe]
646 *) Added the common error/ tree to the build/install targets
647 (similar to the common icons/ tree) for the multi-language error
648 messages that Lars committed earlier. [William Rowe]
650 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
652 *) Added a default commented-out mod_ldap and mod_auth_ldap
653 configuration to httpd-std.conf and httpd-win.conf
656 *) Added documentation for mod_ldap and mod_auth_ldap.
659 *) Enabled negative caching on attribute comparisons in the LDAP cache.
660 Fixed a problem where the default cache TTL was set in milliseconds
661 not microseconds causing the cache to time out almost immediately.
664 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
665 module code to follow APR. [Graham Leggett]
667 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
668 cleaned up when the connection pool pool is cleaned up.
671 *) Fix a minor issue with Jeff Trawick's mod_include
672 patch. Without this patch, the code will just allocate
673 more bytes in get_combined_directive than are needed.
676 *) Added the LDAP authentication module mod_auth_ldap.
677 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
679 *) Added the LDAP cache and connection pooling module mod_ldap.
680 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
682 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
683 by allowing a module to disable itself if its prerequisites are not
684 met. [Justin Erenkrantz]
686 Changes with Apache 2.0.24
688 *) Fix a couple of issues in mod_include when the tag appeared at
689 offsets near 8192 in the file being parsed. [Jeff Trawick]
691 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
692 reached. [Jeff Trawick]
694 *) Numerous improvements to the Win32 build system. Introduced command line
695 builds without requiring .mak files for MSVC 6.0 and later versions.
696 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
699 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
700 reporting of uninstalled services and other error conditions, and changed the
701 default service name to Apache2. [William Rowe]
703 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
704 compatibility with existing Apache 1.3 Win32 Apache management utilites.
705 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
707 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
708 [William Rowe, Greg Ames]
710 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
711 and RemoveCharset directives. [William Rowe]
713 *) The Unix MPMs other than perchild now allow child server
714 processes to use the accept mutex when starting as root and
715 using SysV sems for the accept mutex. Previously, this
716 combination would lead to fatal errors in the child server
717 processes. perchild can't use SysV sems because of security
718 issues. [Jeff Trawick, Greg Ames]
720 *) Added Win32 revision stamp resources to all http binaries
721 (including modules/ and support/ tools.) PR7322 [William Rowe]
723 *) Fix ap_rvprintf to support more than 4K of data at one time.
724 [Cody Sherr <csherr@covalent.net>]
726 *) We have always used the obsolete/deprecated Netscape syntax
727 for our tracking cookies; now the CookieStyle directive
728 allows the Webmaster to choose the Netscape, RFC2109, or
729 RFC2965 format. The new CookieDomain directive allows the
730 setting of the cookie's Domain= attribute, too. PR #s 5006,
731 5023, 5920, 6140 [Ken Coar]
733 *) Tweak server/Makefile so that the rules for generating exports.c
734 are compatible with make utilities which don't expand wildcards
735 in a dependency list (e.g., OS/390 make, certain levels of GNU
736 make). [Jeff Trawick]
738 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
740 *) Begin to sanitize the MPM configuration directives. Now, all
741 MPMs use the same functions for all common MPM directives. This
742 should make it easier to catch all bugs in these directives once.
743 [Cody Sherr <csherr@covalent.net>]
745 *) Close a major resource leak. Every time we had issued a
746 graceful restart, we leaked a socket descriptor.
749 *) Fix a problem with the new method code. We need to cast
750 the 1 to an apr_int64_t or it will be treated as a 32-bit
751 integer, and it will wrap after being shifted 32 times.
752 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
754 *) Fix a bug in mod_expires. Previous to this patch, if you
755 told mod_expires to add 604800 seconds to the last-modified
756 time, it actually added 604800 usec's to the last-modified time,
757 so that when looking at the response it looked like nothing
758 had been done. The root of the problem was that we always compute
759 time in usec's, but we ask users to input sec's. This means we
760 need to convert to usec's before using those values.
763 *) The worker MPM now handles shutdown and restart requests. It
764 definitely isn't perfect, but we do stop the servers correctly.
765 The biggest problem right now is that SIGHUP causes the server to
766 just die. [Ryan Bloom]
768 Changes with Apache 2.0.23
770 *) Use the prefork MPM by default on Unix. [various]
772 *) Added a systray icon monitor application for Win32.
773 [Mladen Turk <mturk@mappingsoft.com>]
775 *) mod_rewrite: Fix the line ending on some non-Unix systems for
776 messages written to the rewrite log.
777 [Richard Labennett <rlabenn@us.ibm.com>]
779 *) All mod_autoindex query parsing is now quietly quashed with the
780 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
781 still drops the column sort <a href>'s for the column headers, but
782 IgnoreClient is required to ignore these Query options entirely.
785 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
786 to allow the client to select plain, FancyIndexing or HTMLTable
787 formatting, V=[0|1] to inhibit or enable version sorting, and
788 P=pattern to return only specific files. The old Query Arguments
789 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
790 as before), and O=A|D for ordering ascending or descending.
793 *) Fixed an error in mod_include's directive parsing routines which
794 caused #if, #elif, and #else expressions containing backslashes
795 to be improperly evaluated. [Cliff Woolley]
797 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
798 drop the icon column, SuppressRules to drop the <hr> elements,
799 and HTMLTable to create rudimentary HTML table listings (implies
800 FancyIndexing). [William Rowe]
802 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
803 from Apache 1.3.15. This is needed for two reasons, first, given
804 multiple machines within a server farm, ETags and Last-Modified
805 stamps won't correspond from machine to machine, and second, many
806 Unixes don't capture changes to the date or time stamp of existing
807 files, since these don't modify the dirent itself. [William Rowe]
809 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
810 and DirectoryWidth options from Apache 1.3.10.
811 [William Rowe, Ken Coar]
813 *) Eliminated FancyIndexing directive, deprecated early in Apache
814 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
816 *) mod_autoindex now excludes any file names that would result in
817 an error, other than a success or redirect. Also optimized
818 the parent directory, always included except in the URI '/'.
821 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
822 negotiated index pages, and prevent the server from defaulting
823 to an autoindex of the directory. mod_negotiation will now die
824 with a 500 Internal Error if it could match some filenames
825 (e.g. for mod_dir) but none can be served. mod_negotation now
826 refuses to serve any file with an extention that mod_mime doesn't
827 recognize, and wasn't part of the request. [William Rowe]
829 *) Eliminate mod_cgi's handling of .exe files without the .exe file
830 extension. This is already handled by multiviews, if the admin
831 wishes to AddHandler .exe or define a content type handler and
832 associate .exe files with that content type. Multiviews must be
833 enabled to allow these to be served. [William Rowe]
835 *) Speed up the server's response to a spike in incoming workload
836 or restarts by assigning empty scoreboard slots to new processes
837 when they are available. [Greg Ames]
839 *) Add a handler to mod_includes.c. This handler is designed to
840 implement the XbitHack directive. This can't be done with a
841 fixup, because we need to check the content-type, which is
842 only available in the handler phase. [Ryan Bloom]
844 *) Make the includes filter check return codes from filters lower in
845 the filter chain. If a lower level filter returns an error, then
846 the request needs to stop immediately. This allows mod_include to
847 stop parsing data once a lower filter recognizes an error.
850 *) Add the ability to extend the methods that Apache understands
851 and have those methods <limit>able in the httpd.conf. It uses
852 the same bit mask/shifted offset as the original HTTP methods
853 such as M_GET or M_POST, but expands the total bits from an int to
854 an ap_int64_t to handle more bits for new request methods than
855 an int provides. [Cody Sherr <csherr@covalent.net>]
857 *) Fix broken mod_mime behavior in merging its arguments. Possible
858 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
860 *) Solve many mod_ssl porting issues (too many to detail) with
861 help from the whole team, but most notably [Ralf S. Engelschall,
862 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
863 Doug MacEachern, William Rowe, Cliff Woolley]
865 *) More stall fixes for the threaded & worker mpm's.
866 Make mod_status output more accurate. Don't
867 count workers in processes which aren't actively
868 serving requests. [Greg Ames]
870 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
872 *) Add a single listener/multiple worker MPM. This MPM is
873 definately not fully correct, but it allows us to solve many
874 of the problems that exist in the threaded MPM. This is a
875 modified version of the threaded MPM. [Ryan Bloom]
877 *) Improve content generation throughout Apache, providing closer
878 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
879 Transitional specifications. [William Rowe]
881 Changes with Apache 2.0.22
883 *) Fix a problem where the threaded MPM stalls after restarts or
884 segfaults. Also prevent multiple active processes from using
885 the same scoreboard slot. [Greg Ames]
887 *) Apache/Win32 now fills in the service description with Apache's
888 server version string, including loaded and advertised modules.
891 *) Improved support for the Win32 build, to recover gracefully from
892 missing apr or apr-util directories or the awk interpreter,
893 create the proper cgi-bin examples, including a test-cgi.bat, and
894 fix the perl shebang line for printenv.pl, when installing from
895 the build environment. [William Rowe]
897 *) Fix a segfault in threaded.c caused by passing uninitialized
898 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
900 *) Use new APR number conversion functions to reduce CPU consumption
901 when setting the content length, and in mod_log_config.
904 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
905 where HEAD response headers were being repeated twice for
906 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
907 problem in the http_header filter was exposed by the recent rewrite
908 of the content_length filter. [Taketo Kabe, Bill Stoddard]
910 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
911 restarts. A garbage pointer to a vhost's server_rec from the
912 previous generation was being left around under certain
913 conditions. [Greg Ames]
915 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
916 used to appear as '(none', without the closing paren.
917 [Günter Knauf <eflash@gmx.net>]
919 *) Improve the exports generating awk script. In the past, we had
920 work around problems in the awk script by avoiding some #if and
921 #ifdefs. This has bitten us many times in generating the exports.c
922 file. This improvement allows corrects the header file parsing.
923 [Sander Striker <striker@apache.org>]
925 Changes with Apache 2.0.21
927 *) Resolve the Win32 htpasswd bug, where a file that existed would be
928 overwritten, regardless of the -c flag.
929 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
931 *) Introduce connection sub-pools into ab. Truncating the lifetime
932 of these allocations means that ab no longer perpetually grows
933 its working set, running out of memory on large request attempts.
936 *) Make scoreboard creation a hook. This allows management
937 modules to have access to the scoreboard at the time that it is
938 created, and at every restart request.
939 [Cody Sherr <csherr@covalent.net>]
941 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
942 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
943 daemon index actually used in the scoreboard. I also
944 updated the pertinent calls. [Paul J. Reder]
946 *) Win32: Prevent listening sockets from being inherited by
947 the Apache child process, CGI scripts, rotatelog process
948 etc. If the Apache child process segfaults, any processes
949 that the child started are not reaped. Prior to this fix,
950 these processes inherited the listening sockets which sometimes
951 prevented the restarted Apache child process from accepting
952 connections (ie, the server would hang).
955 *) Provide vhost and request strings when ExtendedStatus is on.
958 *) Fix some issues with the pod and prefork: check the pod *after*
959 processing a connection so that a server processing a time-
960 consuming request bails out as soon as practical; when the
961 parent process wakes up a server process via connect(), use an
962 APR timeout on the connect() so that we don't hang for a long
963 time if there aren't server processes around to do accept().
964 [Jeff Trawick, Greg Ames]
966 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
967 spends a lot of time in apr_table_get calls. Using the default
968 httpd.conf, the tables for languages and charsets are somewhat
969 large, so the time spent scanning them on each request is
970 significant. Replacing the tables with hash tables provides
971 a nice speedup. [Brian Pane <bpane@pacbell.net>]
973 *) Add two functions to allow modules to access random parts of the
974 scoreboard. This allows modules compiled for one MPM to access the
975 scoreboard, even if it the server was compiled for another MPM.
976 [Harrie Hazewinkel <harrie@covalent.net>]
978 Changes with Apache 2.0.20
980 *) Fix problem in content-length filter where the filter would
981 buffer all the output from a CGI before sending any bytes
982 down the filter stack to the network. This problem would cause
983 significant memory consumption if the CGIs generated
984 lots of bytes. [Bill Stoddard]
986 *) Get non-blocking CGI pipe reads working with the bucket brigades.
989 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
992 *) Fix a bug in the threaded MPM that would cause it to kill off all
993 workers immediately after starting if the number of workers started
994 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
996 Changes with Apache 2.0.19
998 *) Fix problem with threaded MPM. The problem was that if each child
999 process was busy serving a single long-lived request and the server
1000 was sent a graceful restart signal, the server would stop serving
1001 requests. This would happen because each child process would wait to
1002 die until the last thread was done, and the parent wouldn't spawn any
1003 new children until a process died. Now, the parent looks at the fact
1004 that the children are dying gracefully, and starts new children.
1005 Those new children only start enough threads to compliment the number
1006 of threads in the other child process that shares the same spot in
1007 the scoreboard. In this way, we make sure to never go over
1008 MaxClients. [Ryan Bloom]
1010 *) modified mod_negotiation and mod_autoindex to speed up by almost a
1011 factor of two on apr_dir_read()-enhanced platforms, such as Win32
1012 and OS2, by calling ap_sub_request_lookup_dirent() with the results
1013 already provided by apr_dir_read(). [William Rowe]
1015 *) mod_file_cache is now more robust to filtering and serves requests
1016 slightly more efficiently. [Cliff Woolley]
1018 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
1019 Module was calling ap_rwrite() followed by ap_rflush() but the
1020 served content was not being displayed in the browser. Inspection
1021 of the output stream revealed that the first data chunk was
1022 missing the trailing CRLF required by the RFC. [Bill Stoddard]
1024 *) apxs no longer generates ap_send_http_header() in the example handler
1026 *) Fix an ab problem which could cause a divide-by-zero exception
1027 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
1028 [Ian Holsman <ianh@cnet.com>]
1030 *) Solve case-insensitive platforms' confusion about negotiated
1031 filenames, allowing files of differnt case to match in choosing
1032 the document to serve. [William Rowe]
1034 *) Fix brokenness when ThreadsPerChild is higher than the built-in
1035 limit. We left ap_threads_per_child at the higher value which
1036 led to segfaults when doing certain scoreboard operations.
1039 *) Fix seg faults and/or missing output from mod_include. The
1040 default_handler was using the subrequest pool for files and
1041 MMAPs, even though the associated APR structures typically
1042 live longer than the subrequest. [Greg Ames]
1044 *) Extend mod_setenvif to support specifying regular expressions
1045 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
1046 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
1047 will cause HAVE_TS to be set if any of the request headers begins
1048 with "TS" and has a value that begins with any character in the
1049 set [a-z]. [Bill Stoddard]
1051 *) httpd children now re-bind themselves to a random CPU on
1052 multiprocessor systems on AIX via bindprocessor() in 2.0.
1053 [Victor J. Orlikowski]
1055 *) Fix htdigest. It would go into a loop in getline when adding
1056 a second user. [Bill Stoddard]
1058 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
1060 *) Automatically generate httpd.exp for AIX.
1061 DSOs now work again on AIX in 2.0
1062 [Victor J. Orlikowski]
1064 *) Add a new request hook, error_log. This phase allows modules
1065 to act on the error log string _after_ it has been written
1066 to the error log. The goal for this hook is to allow monitoring
1067 modules to send the error string to the monitoring agent.
1070 *) Modify mod_echo to make it use filters for input and output.
1071 [Ryan Morgan <rmorgan@covalent.net>]
1073 *) Extend mod_headers to support conditional driven Header
1074 add, append and set. Use SetEnvIf to set an envar and conditionally
1075 add/append/set headers based on this envar thusly:
1077 SetEnvIf TSMyHeader value HAVE_TSMyHeader
1078 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
1080 If the request contains header "TSMyHeader: value" then header
1081 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
1084 *) Extend mod_headers to support using format specifiers on Header
1085 add, append and set header values. Two format specifiers are supported:
1087 %t - reports, in UTC microseconds since the epoch, when the
1088 request was received.
1090 %D - reports the time, in microseconds, between when the request was
1091 received and the response sent.
1094 Header add MyHeader "This request served in %D microseconds. %t"
1096 results in a header being added to the response that looks like this:
1098 MyHeader: This request served in D=5438 microseconds. t=991424704447256
1102 *) Fix reset_filter(). We need to be careful how we remove filters.
1103 If we set r->output_filters to NULL, we also have to reset the
1104 connection's filters. [John Sterling]
1106 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
1108 *) Add a check to ap_die() to make sure the filter stack is sane and
1109 contains the correct basic filters when an error occurs. This fixes
1110 a problem where headers are not being sent on error. [John Sterling]
1112 *) New Header directive 'echo' option. "Header echo regex" will
1113 cause any headers received on the request that match regex to be
1114 echoed to (included in) the response headers.
1117 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
1118 This prevented the inclusion of apr_compat.h. PR #7773
1119 [Oleg Broytmann <phd@phd.pp.ru>]
1121 *) Moved util_uri to the apr-util library. This required a bunch of
1122 apr_name changes for the uri utility functions. [Justin Erenkrantz]
1124 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
1125 insert_filter phase so that other filters are not bypassed by default.
1128 *) Reimplement mod_headers as an output filter. mod_headers can now
1129 add custom headers to inbound requests using the RequestHeader directive
1130 and to responses using the same old Header directive. [Graham Leggett]
1132 Changes with Apache 2.0.18
1134 *) Fix command-line processing so that if a bad argument is specified
1135 Apache will exit. [Jeff Trawick]
1137 *) Change the make targets and rules to be consistent in all of the
1138 Apache-owned source trees. [Roy Fielding]
1140 *) Fix processing of the TRACE method. Previously we passed bogus
1141 parms to form_header_field() and it overlaid some vhost structures,
1142 resulting in a segfault in check_hostalias().
1143 [Greg Ames, Jeff Trawick]
1145 *) Win32: Add support for reliable piped logs. If the logging process
1146 goes down, Apache will automatically restart it. This function has
1147 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
1150 *) Do not start piped log processes during the config file
1151 preflight. This change also circumvents a problem on
1152 Windows where the rotatelog processes created during preflight
1153 was not getting cleaned up properly.
1156 *) add "Request Phase Participation" info to mod_info
1159 *) Make first phase changes to the scoreboard data structures in
1160 preparation for the rewriting of the scoreboard per my posted
1161 design notes. [Paul J. Reder]
1163 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
1164 and apr-util, allow it to be overridden by the configure command-line
1165 (default="--silent") and introduce LT_LDFLAGS to replace what we were
1166 formerly abusing as LTFLAGS. [Roy Fielding]
1168 *) Clean up the reporting of incorrect closing container tags.
1169 [Barrie Slaymaker <barries@slaysys.com>]
1171 *) Simplify the configure process by moving all libtool stuff to APR
1172 and moving hints.m4 inline. [Roy Fielding]
1174 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
1175 of functions used by mod_proxy for export in the DLL
1176 [Ian Holsman <IanH@cnet.com>]
1178 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
1179 request body from its stdin but no reqest body is being written to
1180 the cgi. [Jeff Trawick]
1182 *) mod_log_config: %c connection status incorrectly logged
1183 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
1186 *) Get mod_cern_meta working under Windows
1189 *) Create Files, and thus MMAPs, out of the request pool, not the
1190 connection pool. This solves a small resource leak that had us
1191 not closing files until a connection was closed. In order to do
1192 this, at the end of the core_output_filter, we loop through the
1193 brigade and convert any data we have into a single HEAP bucket
1194 that we know will survive clearing the request_rec.
1195 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
1198 *) Completely revamp configure so that it preserves the standard make
1199 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
1200 the configure additions to EXTRA_* variables. Also, allow the user
1201 to specify NOTEST_* values for all of the above, which eliminates the
1202 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
1203 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1204 avoid pointless duplications. Fix the order in which flags are given
1205 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1206 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1207 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1208 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1210 *) Get mod_tls to compile/work better on Windows. PR #7612
1211 [Bernhard Schrenk <b.schrenk@improx.com>]
1213 *) Fix shutdown/restart hangs in the threaded MPM.
1214 [Jeff Trawick, Greg Ames, Ryan Bloom]
1216 *) Removed the keptalive boolean from conn_rec because it is now only
1217 used by a single routine and can be replaced by a local variable.
1218 [Greg Stein, Ryan Bloom, Roy Fielding]
1220 *) Patch prefork to put enough of the signal processing back in so that
1221 signals are all handled properly now. The previous patch fixed the
1222 deadlock race condition, but broke the user directed signal handling.
1223 This fixes it to work the way it did before my previous prefork patch
1224 (primarily, SIGTERM is now working).
1226 *) Change how input filters decide how much data is returned to the
1227 higher filter. We used to use a field in the conn_rec, with this
1228 change, we use an argument to ap_get_brigade to determine how much
1229 data is retrieved. [Ryan Bloom]
1231 *) Fix seg fault at start-up introduced by Ryan's change to enable
1232 modules to specify their own logging tags. mod_log_config
1233 registers an optional function, ap_register_log_handler().
1234 ap_register_log_handler() was being called by http_core before
1235 the directive hash table was created. This patch creates the
1236 directive hash table before ap_register_log_handler() is
1237 registered as an optional function.
1238 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1240 *) Add ap_set_int_slot() function
1241 [John K. Sterling <sterling@covalent.net>]
1243 *) Under certain circumstances, Apache did not supply the
1244 right response headers when requiring authentication.
1245 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1246 (This is a port of the change that went into Apache 1.3.19.)
1248 *) Allow modules to specify their own logging tags. This basically
1249 allows a module to tell mod_log_config that when %x is encountered
1250 a specific function should be called. Currently, x can be any single
1251 character. It may be more useful to make this a string at some point.
1254 Changes with Apache 2.0.17
1256 *) If a higher-level filter handles the the byterange aspects of a
1257 request, then the byterange filter should not try to redo the
1258 work. The most common case of this happening, is a byterange
1259 request going through the proxy, and the origin server handles
1260 the byterange request. The proxy should ignore it.
1261 [Graham Leggett <minfrin@sharp.fm>]
1263 *) Changed the threaded mpm to have child_main join to each of the
1264 worker threads to make sure the kids are all gone before child_main
1265 exits after a signal (cleanup from perform_idle_server_maintenance).
1266 This is an extension of Ryans recent commit to make the child_main
1269 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1270 report if their threads are dynamic or static. Finally, this also
1271 implements a new API, ap_show_mpm, which returns the MPM that was
1272 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1274 *) Do not install the binaries from the support directory twice.
1275 [jun-ichiro hagino <itojun@iijlab.net>]
1277 *) The ap_f* functions should flush data to the filter that is passed
1278 in, not the the filter after the one passed in.
1279 [Ryan Morgan <rmorgan@covalent.net>]
1281 *) Make ab work again by changing its native types to apr types and formats.
1282 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1284 *) Move the byterange filter and all of the supporting functions back
1285 to the HTTP module. The byterange filter turned out to be very
1286 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1288 *) Make clean, distclean, and extraclean consistently according to the
1289 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1291 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1292 This may have been causing problems stopping processes in the threaded
1295 *) Fix content-length in mod_negotiation to a long int representation.
1298 *) Remove BindAddress from the default config file.
1299 [giles@nemeton.com.au]
1301 *) Allow module authors to add a module to their Apache build using
1302 --with-module, without re-running buildconf. The syntax is:
1303 --with-module=module_type:/path/to/module.c
1304 The configure script will copy the module.c file to
1305 modules/module_type, and it will be added to the relevant Makefiles.
1306 currently, this only works for static modules. [Ryan Bloom]
1308 *) Changes required to make prefork clean up idle children properly.
1309 There was a window during which a starting worker deadlocks when
1310 an idle cleanup arrives before it completes init. Apache then keeps
1311 trying to cleanup the same deadlocked worker forever (until higher
1312 pids come along, but it still will never reduce below the deadlocked
1313 pid). Thus the number of children would not reduce to the correct
1314 idle level. [Paul J. Reder]
1316 Changes with Apache 2.0.16
1318 *) Change the default installation directory to /usr/local/apache2,
1319 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1321 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1324 *) Get MaxRequestsPerChild working with the Windows MPM.
1327 *) Make generic hooks to work, with mod_generic_hook_import/export
1328 experimental modules. [Ben Laurie, Will Rowe]
1330 *) Fix segfaults for configuration file syntax errors such as
1331 "<Directory>" followed by "</Directory" and
1332 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1334 *) Cleanup the --enable-layout option of configure. This makes
1335 us use a consistent location for the config.layout file, and it
1336 makes configure more portable.
1337 [jun-ichiro hagino <itojun@iijlab.net>]
1339 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1340 csv/gnuplot format, rudimentary ssl support and various other tweaks
1341 to make results more true to what is measured. The upshot of this it
1342 turns out that 'ab' has often underreported the true performance of
1343 apache. Often by a order of magnitude :-) See talk/paper of Sander
1344 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1345 [Dirk-Willem van Gulik]
1347 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1348 storage leak this ensures that some unnecessary pipes are closed.
1351 *) Performance: Add quick_handler hook. This hook is called at the
1352 very beginning of the request processing before location_walk,
1353 translate_name, etc. This hook is useful for URI keyed content
1354 caches like Mike Abbott's Quick Shortcut Cache.
1357 *) top_module global variable renamed to ap_top_module [Perl]
1359 *) Move ap_set_last_modified to the core. This is a potentially
1360 controversial change, because this is kind of HTTP specific. However
1361 many protocols should be able to take advantage of this kind of
1362 information. I expect that headers will need one more layer of
1363 indirection for multi-protocol work, but this is a small step in
1364 the right direction. [Ryan Bloom]
1366 *) Enable mod_status by default. This matches what Apache 1.3 does.
1369 *) Add a ScriptSock directive to the default config file. This is
1370 only enabled when mod_cgid is used.
1371 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1373 Changes with Apache 2.0.15
1375 *) Untangled the buildconf script and eliminated the need for build's
1376 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1377 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1379 *) Win32: Don't accept more connections than we have worker threads
1383 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1384 to fork() new child processes.
1387 *) Fix a major security problem with double-reverse lookup checking.
1388 Previously, a client connecting over IPv4 would not be matched
1389 properly when the server had an IPv6 listening socket. PR #7407
1390 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1392 *) Change the way the beos MPM handles polling to allow it to stop and
1393 restart. Problem was the sockets being polled were being reset by
1394 the select call, so once it had accepted a connection it was no
1395 longer listening on the UDP socket we use for shutdown instructions.
1396 APR needs to be altered, patch on it's way. [David Reid]
1398 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1399 on error exit from ap_getline(). Some other code got upset because
1400 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1402 *) Handle ap_discard_request_body() being called more than once.
1403 [Greg Ames, Jeff Trawick]
1405 *) Get rid of an inadvertent close of file descriptor 2 in
1406 mod_mime_magic. [Greg Ames, Jeff Trawick]
1408 *) Add a hook, create_request. This hook allows modules to modify
1409 a request while it is being created. This hook is called for all
1410 request_rec's, main request, sub request, and internal redirect.
1411 When this hook is called, the the r->main, r->prev, r->next
1412 pointers have been set, so modules can determine what kind of
1413 request this is. [Ryan Bloom]
1415 *) Cleanup the build process a bit more. The Apache configure
1416 script no longer creates its own helper scripts, it just
1418 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1420 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1421 proxy requests. [Graham Leggett]
1423 *) Avoid using sscanf to determine the HTTP protocol number in
1424 the common case because sscanf is a performance hog. From
1425 Mike Abbot's Accelerating Apache patch number 6.
1426 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1428 *) Fix a security exposure in mod_access. Previously when IPv6
1429 listening sockets were used, allow/deny-from-IPv4-address rules
1430 were not evaluated properly (PR #7407). Also, add the ability to
1431 specify IPv6 address strings with optional prefix length on Allow
1432 and Deny. [Jeff Trawick]
1434 *) Enhance rotatelogs so that a UTC offset can be specified, and
1435 the logfile name can be formatted using strftime(3). (Brought
1436 forward from 1.3.) [Ken Coar]
1438 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1439 DuplicateHandle on an IOCompletionPort (a practice which
1440 MS "discourages"). The new model does not rely on associating
1441 the completion port with the listening sockets, thus the
1442 completion port can be completely managed within the child
1443 process. A dedicated thread accepts connections off the network,
1444 then calls PostQueuedCompletionStatus() to wake up worker
1445 threads blocked on the completion port.
1448 *) Bring forward the --suexec-umask option which allows the
1449 builder to preset the umask for suexec processes. [Ken Coar]
1451 *) Add a -V flag to suexec, which causes it to display the
1452 compile-time settings with which it was built. (Only
1453 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1455 *) Mod_include should always unset the content-length if the file is
1456 going to be passed through send_parsed_content. There is no to
1457 determine if the content will change before actually scanning the
1458 entire content. It is far safer to just remove the C-L as long
1459 as we are scanning it. [Ryan Bloom]
1461 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1462 request and not Proxy-Authenticate.
1463 [Graham Leggett <minfrin@sharp.fm>]
1465 Changes with Apache 2.0.14
1467 *) Fix content-length computation. We ONLY compute a content-length if
1468 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1469 or we already have all the data. [Ryan Bloom]
1471 *) Report unbounded containers in the config file. Previously, a typo
1472 in the </container> directive could result in the rest of the config
1473 file being silently ignored, with undesired defaults used.
1476 *) Make the old_write filter use the ap_f* functions for the buffering.
1479 *) Move more code from the http module into the core server. This
1480 is core code, basically the default handler, the default input
1481 and output filters, and all of the core configuration directives.
1482 All of this code is required in order for the server to work, with or
1483 without HTTP. The server is closer to working without the HTTP
1484 module, although there is still more to do. [Ryan Bloom]
1486 *) Fix a number of SGI compile warnings throughout the server. Fix some
1487 bad parameters to apr_bucket_read(). Fix a bad statement in
1488 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1489 consistently; we were mixing apr_time_t and time_t in invalid ways
1490 before. In load_file(), call apr_dso_error() instead of
1491 apr_strerror() so that we get a more specific string on some platforms.
1492 PR #6980 [Jeff Trawick]
1494 *) Allow modules to query the MPM about it's execution profile. This
1495 query API can and should be extended in the future, but for now,
1496 max_daemons, and threading or forking is a very good start.
1497 [Jon Travis <jtravis@covalent.net>]
1499 *) Modify mod_include to send blocks of data no larger than 9k.
1500 Without this, mod_include will wait until the whole file is parsed,
1501 or the first tag is found to send any data to the client.
1502 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1504 *) Fix mod_info, so that <Directory> and <Location> directives are
1505 not displayed twice when displaying the current configuration.
1506 [Ryan Morgan <rmorgan@covalent.net>]
1508 *) Add config directives to override DEFAULT_ERROR_MSG and
1509 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1510 [Dan Rench <drench@xnet.com>]
1512 *) Get mod_info building and loading on Win32. [William Rowe]
1514 *) Begin to move protocol independant functions out of mod_http. The goal
1515 is to have only functions that are HTTP specific in the http directory.
1518 Changes with Apache 2.0.13
1520 *) Don't assume that there will always be multiple calls to the byterange
1521 filter. It is possible that we will need to do byteranges with only
1522 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1524 *) Move the error_bucket definition from the http module to the
1525 core server. Every protocol will need this ability, not just
1528 Changes with Apache 2.0.12
1530 *) Modify mod_file_cache to save pre-formatted strings for
1531 content-length and last-modified headers for performance.
1532 [Mike Abbot <mja@trudge.engr.sgi.com>]
1534 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1535 [Jon Travis <jtravis@covalent.net>]
1537 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1538 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1540 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1541 without ever filling it out. This fixes PR 7271.
1542 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1543 Cliff Woolley <cliffwoolley@yahoo.com>]
1545 *) Add a couple of GCC attribute tags to printf style functions.
1546 [Jon Travis <jtravis@covalent.net>]
1548 *) Add the correct language tag for interoperation with the Taiwanese
1549 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1551 *) Migrate the perchild MPM to use the new apr signal child, and
1552 APR thread functions. [Ryan Bloom]
1554 *) Close one copy of the CGI's stdout before creating the new process.
1555 The CGI will still have stdout, because we have already dup'ed it.
1556 This keeps Apache from waiting forever to send the results of a CGI
1557 process that has forked a long-lived child process.
1558 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1560 *) Remove the rest of the pthreads functions from the threaded MPM.
1561 This requires the APR support for a signal thread that was just
1564 *) Make mod_dir use a fixup for sending a redirect to the browser.
1565 Before this, we were using a handler, which doesn't make much
1566 sense, because the handler wasn't generating any data, it would
1567 either return a redirect error code, or DECLINED. This fits the
1568 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1570 *) Make the threaded MPM use APR threads instead of pthreads.
1573 *) Get mod_tls to the point where it actually appears to work in all cases.
1576 *) implement --enable-modules and --enable-mods-shared for "all" and
1577 "most". [Greg Stein]
1579 *) Move the threaded MPM to use APR locks instead of pthread locks.
1582 *) Rename mpmt_pthread to threaded. This is more in line with the
1583 fact that mpmt_pthread shouldn't be using pthreads directly, and
1584 it is a smaller name that doesn't tie into anything.
1587 *) Rename the module structures so that the exported symbol matches
1588 the file name, and it is easier to automate the installation
1589 process (generating LoadModule directives from the module filenames).
1592 *) Remove the coalesce filter. With the ap_f* functions, this filter
1593 is no longer needed. [Ryan Bloom]
1595 Changes with Apache 2.0.11
1597 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1598 added feature of allowing a uid/gid per child process. If no
1599 uid/gid is specified, then Perchild behaves exactly like dexter.
1602 *) Get perchild building again. [Ryan Bloom]
1604 *) Don't disable threads just because we are using the prefork MPM.
1605 If somebody wants to compile without threads, they must now add
1606 --disable-threads to the configure command line. [Ryan Bloom]
1608 *) Begin to move the calls to update_child_status into common code, so
1609 that each individual MPM does not need to update the scoreboard itself.
1612 *) Allow mod_tls to compile under Unix boxes where openssl has been
1613 installed to the system include files.
1614 [Gomez Henri <new-httpd@slib.fr>]
1616 *) Cleanup the mod_tls configure process. This should remove any need
1617 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1618 configure doesn't check that yet. [Ryan Bloom]
1620 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1621 vital that you read modules/tls/README before attempting to build
1624 *) Fix a potential seg fault on all platforms. David Reid fixed this
1625 on BEOS, but the problem could happen anywhere, so we don't want
1626 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1628 *) Add new LogFormat directive, %D, to log time it takes to serve a
1629 request in microseconds. [Bill Stoddard]
1631 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1632 SetOutputFilter. This corresponds nicely with the other Set
1633 directives, which operate on containers while the Add* directives
1634 tend to work directly on extensions. [Ryan Bloom]
1636 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1637 functions for the buffering so that we don't need to compute
1638 the length of the headers before we actually create the header
1639 buffer. [Ryan Bloom]
1641 *) Allow filters to buffer data using the ap_f* functions. These have
1642 become macros that resolve directly to apr_brigade_*.
1645 *) Get the Unix MPM's to do a graceful restart again. If we are going
1646 to register a cleanup with ap_cleanup_scoreboard, then we have to
1647 kill the cleanup with the same function, and that function can't be
1648 static. [Ryan Bloom]
1650 *) Install all required header files. Without these, it was not
1651 possible to compile some modules outside of the server.
1654 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1655 forward from 1.3 to 2.0, we missed a single line, which broke regex
1656 aliases. [Ryan Bloom]
1658 *) We have a poor abstraction in the protocol. This is a temporary
1659 hack to fix the bug, but it will need to be fixed for real. If
1660 we find an error while sending out a custom error response, we back
1661 up to the first non-OK request and send the data. Then, when we send
1662 the EOS from finalize_request_protocol, we go to the last request,
1663 to ensure that we aren't sending an EOS to a request that has already
1664 received one. Because the data is sent on a different request than
1665 the EOS, the error text never gets sent down the filter stack. This
1666 fixes the problem by finding the last request, and sending the data
1667 with that request. [Ryan Bloom]
1669 *) Make the server status page show the correct restart time, and
1670 thus the proper uptime. [Ryan Bloom]
1672 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1673 should reduce the amount of duplicate code that is required to
1674 create CGI processes.
1675 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1677 *) ap_new_connection() closes the socket and returns NULL if a socket
1678 call fails. Usually this is due to a connection which has been
1679 reset. [Jeff Trawick]
1681 *) Move the Apache version information out of httpd.h and into release.h.
1682 This is in preparation for the first tag with the new tag and release
1683 system. [Ryan Bloom]
1685 *) Begin restructuring scoreboard code to enable adding back in
1686 the ability to use IPC other than shared memory.
1687 Get mod_status working on Windows again. [Bill Stoddard]
1689 *) Make mod_status work with 2.0. This will work for prefork,
1690 mpmt_pthread, and dexter. [Ryan Bloom]

1701 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1703 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1704 'extra' stat's for user/group since they should never occur, and now
1705 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1706 volumes. [William Rowe]
1708 *) Adopt apr features to simplify mod_includes. This changes the
1709 behavior of the USER_NAME variable, unknown uid's are now reported
1710 as USER_NAME="<unknown>" rather than the old user#000 result.
1711 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1713 *) Adopt apr features for simplifing mod_userdir, and accept the new
1714 Win32/OS2 exceptions without hiccuping. [William Rowe]
1716 *) Replace configure --with-optim option by using and saving the
1717 environment variable OPTIM instead. This is needed because configure
1718 options do not support multiple flags separated by spaces.
1721 *) Fix some byterange handling. If we get a byte range that looks like
1722 "-999999" where that is past the end of the file, we should return
1723 a PARTIAL CONTENT status code, and return the whole file as one big
1724 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1726 *) Make the error bucket a real meta-data bucket. This means that the
1727 bucket length is 0, and a read returns NULL data. If one of these
1728 buckets is passed down after the headers are sent, this data will
1729 just be ignored. [Greg Stein]
1731 *) The prefork MPM wasn't killing child processes correctly if a restart
1732 signal was received while the process was serving a request. The child
1733 process would become the equivalent of a second parent process. If
1734 we break out of the accept loop, then we need to do die after cleaning
1735 up after ourselves. [Ryan Bloom]
1737 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1738 restarts. [Ryan Bloom]
1740 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1741 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1742 performing very expensive owner, group and permission lookups
1743 and allows the server to function until these apr_finfo_t fields
1744 are implemented under Win32. [William Rowe]
1746 *) Support for typedsafe optional functions - that is functions exported by
1747 optional modules, which, therefore, may or may not be present, depending
1748 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1749 for sample code. [Ben Laurie]
1751 *) filters can now report an HTTP error to the server. This is done
1752 by sending a brigade where the first bucket is an error_bucket.
1753 This bucket is a simple bucket that stores an HTTP error and
1754 a string. Currently the string is not used, but it may be needed
1755 to output an error log. The http_header_filter will find this
1756 bucket, and output the error text, and then return
1757 AP_FILTER_ERROR, which informs the server that the error web page
1758 has already been sent. [Ryan Bloom]
1760 *) If we get an error, then we should remove all filters except for
1761 those critical to serving a web page. This fixes a bug, where
1762 error pages were going through the byterange filter, even though
1763 that made no sense. [Ryan Bloom]
1765 *) Relax the syntax checking of Host: headers in order to support
1766 iDNS. PR#6635 [Tony Finch]
1768 *) Cleanup the byterange filter to use the apr_brigade_partition
1769 and apr_bucket_copy functions. This removes a lot of very messy
1770 code, and hopefully makes this filter more stable.
1773 *) Remove AddModule and ClearModuleList directives. Both of these
1774 directives were used to ensure that modules could be enabled
1775 in the correct order. That requirement is now gone, because
1776 we use hooks to ensure that modules are in the correct order.
1779 *) When SuExec is specified, we need to add it to the list of
1780 targets to be built. If we don't, then any changes to the
1781 configuration won't affect SuExec, unless 'make suexec' is
1782 specifically run. [Ryan Bloom]
1784 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1785 the APR_XTHREAD argument to open a file for consumption by
1786 parallel threads on win32. [William Rowe]
1788 *) Correct a bug in determining when we follow symlinks. The code
1789 expected a stat -1 result, not an apr_status_t positive error.
1790 Also check if the APR_FINFO_USER fields are valid before we
1791 follow the link. [William Rowe]
1793 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1794 mpm_common.c. These functions are only valid on some platforms,
1795 so they should not be in the main-line code. [Ryan Bloom]
1797 *) Remove ap_chdir_file(). This function is not thread-safe,
1798 and nobody is currently using it. [Ryan Bloom]
1800 *) Do not try to run make depend if there are no .c files in the
1801 current directory, doing so makes `make depend` fail.
1804 *) Update highperformance.conf to work with either prefork or
1805 pthreads mpms. [Greg Ames]
1807 *) Stop checking to see if this is a pipelined request if we know
1808 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1809 This keeps us from making an extra read call when serving a 1.0
1810 request. [Ryan Bloom and Greg Stein]
1812 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1813 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1814 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1816 *) Fix the RFC number mentioned when complaining about a missing
1817 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1819 *) Fix an endless loop in ab which occurred when ab was posting
1820 and the server dropped the connection unexpectedly.
1823 *) Fix a segfault while handling request bodies in ap_http_filter().
1824 This problem has been seen with mod_dav usage as well as with
1825 requests where the body was just being discarded. [Jeff Trawick]
1827 *) Some adjustment on the handling and automatic setting (via
1828 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1829 add the capability to specify flags (NOTEST_CFLAGS and
1830 NOTEST_LDFLAGS) which are used to compile Apache, but
1831 not used during the configuration process. Useful for
1832 flags like "-Werror". [Jim Jagielski]
1834 *) Stop using environment variables to force debug mode or
1835 no detach. We now use the -D command line argument to
1836 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1837 [Greg Stein, Ryan Bloom]
1839 *) Change handlers to use hooks. [Ben Laurie]
1841 *) Stop returning copies of filenames from both apr_file_t and
1842 apr_dir_t. We pstrdup the filenames that we store in the
1843 actual structures, so we don't need to pstrdup the strings again.
1846 *) mod_cgi: Fix some problems where the wrong error value was being
1847 traced. [Jeff Trawick]
1849 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1852 *) Add generic hooks. [Ben Laurie]
1854 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1856 *) Fix a segfault caused by mod_ext_filter when the external filter
1857 program does not exist. [Jeff Trawick]
1859 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1860 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1861 was served through mod_charset_lite (or anything else that would
1862 create a transient bucket in this size range). ap_bucket_make_heap()
1863 silently failed (fixed), transient_setaside() discovered it, but
1864 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1866 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1867 is that some browsers send extra lines at the end of POST requests, and
1868 we don't want to delay sending data back to the user just because the
1869 browser isn't well behaved. [Ryan Bloom]
1871 *) Get SuEXEC working again. We can't send absolute paths to suExec
1872 because it refuses to execute those programs. SuEXEC also wasn't
1873 always recognizing configuration changes made using the autoconf
1876 *) Allow the buildconf process to find the config.m4 files in the correct
1877 order. Basically, we can now name config.m4 files as config\d\d.m4,
1878 and we will sort them correctly when inserting them into the build
1879 process. [Ryan Bloom]
1881 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1882 This also allows mod_cgid to use ap_os_create_priviledged_process,
1883 thus allowing for SuExec execution from mod_cgid. Currently, we do
1884 not support everything that standard SuExec supports, but at least
1885 it works minimally now. [Ryan Bloom]
1887 *) Allow SuExec to be configured from the ./configure command line.
1890 *) Update some of the docs in README and INSTALL to reflect some of
1891 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1893 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1894 need to call sendfile again. This gets us serving large files
1895 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1897 *) Get the support programs building cleanly again.
1898 [Cliff Woolley <cliffwoolley@yahoo.com>]
1900 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1901 current directory logic now backs up over bin/ to determine the
1902 server root from the Apache.exe path.
1904 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1905 loadable modules, dynamic libs are all named libfoo.dll, and the
1906 makefile.win populates the include, lib and libexec directories.
1908 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1909 Apache gets IPv6 listening sockets by default. Additionally, the
1910 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1911 numeric address strings (e.g., "Listen [fe80::1]:8080").
1914 *) Modify the install directory layout. Modules are now installed in
1915 modules/. Shared libraries should be installed in libraries/, but
1916 we don't have any of those on Unix yet. All install directories
1917 are modifyable at configure time. [Ryan Bloom]
1919 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1921 *) Get the functions in server/linked into the server, regardless of
1922 which modules linked into the server. This uses the same hack
1923 for Apache that we use for APR and apr-util to ensure all of the
1924 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1925 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1926 the scripts a bit easier.
1929 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1930 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1932 *) Get all of the auth modules to the point that they will install and
1933 be loadable into the server. Our new build/install mechanism expects
1934 that all modules will have a common name format. The auth modules
1935 didn't use that format, so we didn't install them properly.
1938 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1939 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1941 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1943 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1944 after the end of the response. [Ryan Bloom]
1946 *) Get byterange requests working with responses that do not have a
1947 content-length. Because of the way byterange requests work, we have to
1948 have all of the data before we can actually do the byterange, so we
1949 can compute the content-length in the byterange filter.
1952 *) Get exe CGI's working again on Windows.
1955 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1956 they keep track of whether or not their post config hook has been
1957 called before. Instead of a static variable (which is replaced when
1958 the DSO is loaded a second time), use userdata in the process pool.
1961 Changes with Apache 2.0a9
1963 *) Win32 now requires perl to complete the final install step for users
1964 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1965 and installs the conf, htdocs and htdocs/manual directories.
1968 *) Make mod_include use a hash table to associate directive tags with
1969 functions. This allows modules to implement their own SSI tags easily.
1970 The idea is simple enough, a module can insert it's own tag and function
1971 combination into a hash table provided by mod_include. While mod_include
1972 parses an SSI file, when it encounters a tag in the file, it does a
1973 hash lookup to find the function that implements that tag, and passes
1974 all of the relevant data to the function. That function is then
1975 responsible for processing the tag and handing the remaining data back
1976 to mod_include for further processing.
1977 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1979 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1980 fewer parameters: the local and remote socket addresses were removed
1981 from the parameter list because all required information is available
1982 via the APR socket. [Jeff Trawick]
1984 *) Distribution directory structure reorganized to reflect a
1985 normal source distribution with external install targets.
1988 *) The MPMs that need multiple segments of shared memory now create
1989 two apr_shmem_t variables, one for each shared memory allocation.
1990 the problem is that we can't determine how much memory will be required
1991 for shared memory allocations once we try to allocate more than one
1992 variable. The MM code automatically aligns the shared memory allocations,
1993 so we end up needing to pad the amount of shared memory we want based
1994 on how many variables will be allocated out of the shared memory segment.
1995 It is just easier to create a second apr_shmem_t variable, and two
1996 shmem memory blocks.
1999 *) Cleanup the export list a bit. This creates a single unified list of
2000 functions exported by APR. The export list is generated at configure
2001 time, and that list is then used to generate the exports.c file.
2002 Because of the way the export list is generated, we only export those
2003 functions that are valid on the platform we are building on.
2006 *) Enable logging the cookie with mod_log_config
2007 [Sander van Zoest <sander@covalent.net>]
2009 *) Fix a segfault in mod_info when it reaches the end of the configuration.
2012 *) Added lib/aputil/ as a placeholder for utility functions which are not
2013 specific to the Apache HTTP Server (but do not make sense with APR).
2014 The first utility is "apu_dbm": a set of functions to work with DBM
2015 files. This first version can be compiled for SDBM or GDBM databases.
2018 *) Complete re-write of mod_include. This makes mod_include a filter that
2019 uses buckets directly. This has now served the FAQ correctly.
2020 [Paul Reder <rederpj@raleigh.ibm.com>]
2022 *) Allow modules to specify the first filter in a sub_request when
2023 making the sub_request. This keeps modules from having to change the
2024 output_filter immediately after creating the sub-request, and therefore
2025 skip the sub_req_output_filter. [Ryan Bloom]
2027 *) Update ab to accept URLs with IPv6 literal address strings (in the
2028 format described in RFC 2732), and to build Host header fields in
2029 the same format. This allows IPv6 literal address strings to be
2030 used with ab. This support has been tested against Apache 1.3 with
2031 the KAME patch, but Apache 2.0 does not yet work with this format
2032 of the Host header field. [Jeff Trawick]
2034 *) Accomodate an out-of-space condition in the piped logs and the
2035 rotatelogs.c code, and no longer churn log processes for this
2036 condition. [Victor J. Orlikowski]
2038 *) Add support for partial writes with apr_sendfile() to core_output_filter.
2041 Changes with Apache 2.0a8
2043 *) Add a directive to mod_mime so that filters can be associated with
2047 *) Get multi-views working again. We were setting the path_info
2048 field incorrectly if we couldn't find the specified file.
2051 *) Fix 304 processing. The core should never try to send the headers
2052 down the filter stack. Always, just setup the table in the request
2053 record, and let the header filter convert it to data that is ready
2057 *) More fixes for the proxy. There are still bugs in the proxy code,
2058 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
2062 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
2065 *) APR: Add new apr_getopt_long function to handle long options.
2066 [B. W. Fitzpatrick <fitz@red-bean.com>]
2068 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
2069 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
2070 hostname resolution/address string parsing and building
2071 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
2072 of one of the apr_sockaddr_t structures for a socket. Change
2073 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
2075 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
2076 I have proxied pages with it, cleanup will commence soon.
2079 *) Make the proxy work with filters. This isn't perfect, because we
2080 aren't dealing with the headers properly. [Ryan Bloom]
2082 *) Do not send a content-length iff the C-L is 0 and this is a head
2083 request. [Ryan Bloom]
2085 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
2086 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
2088 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
2090 *) Get the default_handler to stop trying to deal with HEAD requests.
2091 The idea is to let the content-length filter compute the C-L before
2092 we try to send the data. If we can get the C-L correctly, then we
2093 should send it in the HEAD response.
2096 *) The Header filter can now determine if a body should be sent based
2097 on r->header_only. The general idea of this is that if we delay
2098 deciding to send the body, then we might be able to compute the
2099 content-length correctly, which will help caching proxies to cache
2100 our data better. Any handler that doesn't want to try to compute
2101 the content-length can just send an EOS bucket without data and
2102 everything will just work.
2105 *) Add the referer to the error log if one is available.
2106 [Markus Gyger <mgyger@itr.ch>]
2108 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
2109 change, the root of the configuration tree has been exposed to modules
2111 [Ryan Morgan <rmorgan@covalent.net>]
2113 *) Get the core_output_filter to use the bucket interface directly.
2114 This keeps us from calling the content-length filter multiple times
2115 for a simple static request.
2118 *) We are sending the content-type correctly now.
2119 [Ryan Bloom and Will Rowe]
2121 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
2122 a bogus bytes-sent value when the only thing being sent was trailers
2123 and writev() returned an error (or EAGAIN). [Jeff Trawick]
2125 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
2126 hints file to determine which platforms define
2127 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2130 *) APR: add apr_get_home_directory() [Jeff Trawick]
2132 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
2134 *) Not all platforms have INADDR_NONE defined by default. Apache
2135 used to make this check and define INADDR_NONE if appropriate,
2136 but APR needs the check too, and I suspect other applications will
2137 as well. APR now defines APR_INADDR_NONE, which is always a valid
2138 value on all platforms.
2139 [Branko Èibej <brane@xbc.nu>]
2141 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
2142 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
2144 *) Relax the syntax checking of Host: headers in order to support
2145 iDNS. PR#6635 [Tony Finch]
2147 *) When reading from file buckets we convert to an MMAP if it makes
2148 sense. This also simplifies the default handler because the
2149 default handler no longer needs to try to create MMAPs.
2152 *) BUFF has been removed from the main server. The BUFF code will remain
2153 in the code until it has been purged from the proxy module as well.
2156 *) Byteranges have been completely re-written to be a filter. This
2157 has been tested, and I believe it is working correctly, but it could
2158 doesn't work for the Adobe Acrobat plug-in. The output almost matches
2159 the output from 1.3, the only difference being that 1.3 includes
2160 a content-length in the response, and this does not.
2163 *) APR read/write functions and bucket read functions now operate
2164 on unsigned integers, instead of signed ones. It doesn't make
2165 any sense to use signed ints, because we return the error codes,
2166 so if we have an error we should report 0 bytes read or written.
2169 *) Always compute the content length, whether it is sent or not.
2170 The reason for this, is that it allows us to correctly report
2171 the bytes_sent when logging the request. This also simplifies
2172 content-length filter a bit, and fixes the actual byte-reporing
2173 code in mod_log_config.c
2176 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
2177 it says, because it was only used by EOS and FLUSH buckets. Since
2178 neither of those are required at the end of a brigade, this was
2179 really signifying FLUSH_THE_DATA, but that can be determined better
2180 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
2181 buckets now return a length of 0, which is actually the amount of data
2182 read, so they make more sense.
2185 *) Allow the core_output_filter to save some data past the end of a
2186 request. If we get an EOS bucket, we only send the data if it
2187 makes sense to send it. This allows us to pipeline request
2188 responses. As a part of this, we also need to allocate mmap
2189 buckets out of the connection pool, not the request pool. This
2190 allows the mmap to outlive the request.
2193 *) Make blocking and non-blocking bucket reads work correctly for
2194 sockets and pipes. These are the only bucket types that should
2195 have non-blocking reads, because the other bucket types should
2196 ALWAYS be able to return something immediately.
2199 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
2200 server, but use Ctrl+Break to initiate a graceful restart
2201 instead of duplicating behavior. [John Sterling]
2203 *) Patch mod_autoindex to set the Last-Modified header based on
2204 the directory's mtime, and add the ETag header. [William Rowe]
2206 *) Merge the 1.3 patch to add support for logging query string in
2207 such a way that "%m %U%q %H" is the same as "%r".
2210 *) Port three log methods from mod_log_config 1.3 to 2.0:
2211 CLF compliant '-' byte count, method and protocol.
2214 *) Add a new LogFormat directive, %c, that will log connection
2215 status at the end of the response as follows:
2216 'X' - connection aborted before the response completed.
2217 '+' - connection may be kept-alive by the server.
2218 '-' - connection will be closed by the server.
2221 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2222 Unicode file names and paths for Win32, and tag the Content-Type
2223 from mod_autoindex to reflect that charset if the the feature
2224 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2226 *) Compute the content length (and add appropriate header field) for
2227 the response when no content length is available and we can't use
2228 chunked encoding. [Jeff Trawick]
2230 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2231 so that content input filters get dechunked data when using
2232 the default handler. Also removed REQUEST_CHUNKED_PASS.
2235 *) Add mod_ext_filter as an experimental module. This module allows
2236 the administrator to use external programs as filters. Currently,
2237 only filtering of output is supported. [Jeff Trawick]
2239 *) Most Apache functions work on EBCDIC machines again, as protocol
2240 data is now translated (again). [Jeff Trawick]
2242 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2243 the EBCDIC support. They are noops on ASCII machines, so this
2244 type of translation doesn't have to be surrounded by #ifdef
2245 CHARSET_EBCDIC. [Jeff Trawick]
2247 *) Fix mod_include. tag commands work again, and the server will
2248 send the FAQ again. This also allows mod_include to set aside
2249 buckets that include partial buckets.
2250 [Ryan Bloom and David Reid]
2252 *) Add suexec support back. [Manoj Kasichainula]
2254 *) Lingering close now uses the socket directly instead of using
2255 BUFF. This has been tested, but since all we can tell is that it
2256 doesn't fail, this needs to be really hacked on.
2259 *) Allow filters to modify headers and have those headers be sent to
2260 the client. The idea is that we have an http_header filter that
2261 actually sends the headers to the network. This removes the need
2262 for the BUFF to send headers.
2265 *) Charset translation: mod_charset_lite handles translation of
2266 request bodies. Get rid of the xlate version of ap_md5_digest()
2267 since we don't compute digests of filtered (e.g., translated)
2268 response bodies this way anymore. (Note that we don't do it at
2269 all at the present; somebody needs to write a filter to do so.)
2272 *) Input filters and ap_get_brigade() now have a input mode parameter
2273 (blocking, non-blocking, peek) instead of a length parameter.
2276 *) Update the mime.types file to the registered media types as
2277 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2280 *) Namespace protect some macros declared in ap_config.h
2283 *) Support HTTP header line folding with input filtering.
2286 *) Mod_include works again. This should still be re-written, but at
2287 least now we can serve an SHTML page again.
2290 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2291 to both the BUFF and the socket in the conn_rec. Functions that
2292 want to use the BUFF can, functions that want to use the socket,
2293 can. They point to the same place.
2296 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2297 [Tomas "Ögren" <stric@ing.umu.se>]
2299 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2300 associated pool goes away. (APR pipes on OS/2 were already had this
2301 logic.) This resolvs a fatal file descriptor leak with CGIs.
2304 *) The final line of the config file was not being read if there was
2305 no \n at the end of it. This was caused by apr_fgets returning
2306 APR_EOF even though we had read valid data. This is solved by
2307 making cfg_getline check the buff that was returned from apr_fgets.
2308 If apr_fgets return APR_EOF, but there was data in the buf, then we
2309 return the buf, otherwise we return NULL.
2312 *) Piped logs work again in the 2.0 series.
2315 *) Restore functionality broken by the mod_rewrite security fix:
2316 rewrite map lookup keys and default values are now expanded
2317 so that the lookup can depend on the requested URI etc.
2318 PR #6671 [Tony Finch]
2320 *) Tighten up the syntax checking of Host: headers to fix a
2321 security bug in some mass virtual hosting configurations
2322 that can allow a remote attacker to retrieve some files
2323 on the system that should be inaccessible. [Tony Finch]
2325 *) Add a pool bucket type. This bucket is used for data allocated out
2326 of a pool. If the pool is cleaned before the bucket is destroyed, then
2327 the data is converted to a heap bucket, allowing it to survive the
2331 *) Add a flush bucket. This allows modules to signal that the filters
2332 should all flush whatever data they currently have. There is no way
2333 to actually force them to do this, so if a filter ignores this bucket,
2334 that's life, but at least we can try with this.
2337 *) Add an output filter for sub-requests. This filter just strips the
2338 EOS bucket so that we don't confuse the main request's core output
2339 filter by sending multiple EOS buckets. This change also makes sub
2340 requests start to send EOS buckets when they are finished.
2343 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2344 makes ap_bucket_destroy a return void, which is okay because it
2345 used to always return APR_SUCCESS, and nobody ever checked its
2346 return value anyway.
2347 [Cliff Woolley <cliffwoolley@yahoo.com>]
2349 *) Remove the index into the bucket-type table from the buckets
2350 structure. This has now been replaced with a pointer to the
2351 bucket_type. Also add some macros to test the bucket-type.
2354 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2355 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2356 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2357 All _VAR_ flavors changes to _DATA to be absolutely clear.
2360 *) Add support for /, //, //servername and //server/sharename
2361 parsing of <Directory> blocks under Win32 and OS2.
2362 [Tim Costello, William Rowe, Brian Harvard]
2364 *) Remove the function pointers from the ap_bucket type. They have been
2365 replaced with a global table. Modules are allowed to register bucket
2366 types and use then use those buckets.
2369 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2370 once we finish writing the request body to the cgi child process;
2371 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2372 worked without this change (for reasons I don't understand), but large
2373 ones didn't. [Jeff Trawick]
2375 *) Remove file bucket specific information from the ap_bucket type.
2376 This has been moved to a file_bucket specific type that hangs off
2377 the data pointer in the ap_bucket type.
2380 *) Input filtering now has a third argument. This is the amount of data
2381 to read from lower filters. This argument can be -1, 0, or a positive
2382 number. -1 means give me all the data you have, I'll deal with it and
2383 let you know if I need more. 0 means give me one line and one line
2384 only. A positive number means I want no more than this much data.
2386 Currently, only 0 and a positive number are implemented. This allows
2387 us to remove the remaining field from the conn_rec structure, which
2391 *) Big cleanup of the input filtering. The goal is that http_filter
2392 understands two conditions, headers and body. It knows where it is
2393 based on c->remaining. If c->remaining is 0, then we are in headers,
2394 and http_filter returns a line at a time. If it is not 0, then we are
2395 in body, and http_filter returns raw data, but only up to c->remaining
2396 bytes. It can return less, but never more.
2397 [Greg Ames, Ryan Bloom, Jeff Trawick]
2399 *) mod_cgi: Write all of the request body to the child, not just what
2400 the kernel would accept on the first write. [Jeff Trawick]
2402 *) Back out the change that moved the brigade from the core_output_filters
2403 ctx to the conn_rec. Since all requests over a given connection
2404 go through the same core_output_filter, the ctx pointer has the
2408 *) Fix another bug in the send_the_file() read/write loop. A partial
2409 send by apr_send would cause unsent data in the read buffer to
2410 get clobbered. Complete making send_the_file handle partial
2411 writes to the network.
2414 *) Fix a couple of type fixes to allow compilation on AIX again
2415 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2417 *) Fix bug in send_the_file() which causes offset to be ignored
2418 if there are no headers to send.
2421 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2422 filter. Useful for supporting Windows 9* with a binary
2423 compiled on Windows NT.
2426 Changes with Apache 2.0a7
2428 *) Reimplement core_output_filter to buffer/save bucket brigades
2429 across multiple calls to the core_filter. The brigade will be
2430 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2431 thresholds are hit or the EOS bucket is received.
2434 *) Create experimental filter (buffer_filter) that coalesces bytes
2435 into one large buffer before invoking the next filter in the
2436 chain. This filter is particularly useful with the current
2437 implementation of mod_autoindex when it inserted above the
2438 chunk_filter. mod_autoindex generates a lot of brigades that
2439 containing buckets holding just a few bytes each. The
2440 buffer_filter coalesces these buckets into a single large bucket.
2443 *) Add apr_sendfile() support into the core_output_filter.
2446 *) Add apr_sendv() support into the core_output_filter.
2449 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2450 [Mike Abbott <mja@sgi.com>]
2452 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2453 make much sense, because Apache uses buckets instead of BUFFs now.
2456 *) send_the_file now falls back to a read/write loop on platforms that
2457 do not have sendfile.
2458 [Ryan Bloom and Brian Havard]
2460 *) Install apachectl correctly, and substitute the proper values so
2461 that it works again. [Ryan Bloom]
2463 *) Better(??) handle platforms that lack sendfile().
2466 *) APR now has UUID generation/formatting/parsing support.
2469 *) Begin the http_filter. This is an input filter that understands
2470 the absolute basic amount required to parse an HTTP Request. The
2471 goal is to be able to split headers from request body before passing
2472 the data back to the other filters.
2475 *) Bring forward from 1.3.13 the config directory implementation
2478 *) install apxs if it is created
2481 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2482 conversions. [William Rowe]
2484 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2485 ap_add_output_filter(). [Jeff Trawick]
2487 *) Multiple build and configuration fixes
2490 -add datadir and localstatedir substitutions
2492 -fix logfilename misspelling
2493 -fix evaluation of installation dir variables and
2494 -replace $foobar by $(foobar) to be usefull in the makefile
2498 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2499 $CC_FOR_BUILD is still missing
2500 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2501 -add missing "AR=@AR@" to severaly Makefile.in's
2502 -cache result for "struct rlimit"
2503 -compile all helper programs with native and cross compiler
2504 and use the native version to generate header file
2505 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2507 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2509 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2511 *) Fix a bug where a client which only sends \n to delimit header
2512 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2513 message. Start working on ebcdic co-existance with input
2515 [William Rowe, Greg Ames]
2517 *) If mod_so is enabled in the server always create libexec, even
2518 if there are no modules installed in this directory. This is a
2519 requirement for APXS to work correctly.
2522 *) Connection oriented output filters are now stored in the
2523 conn_rec instead of the request_rec. This allows us to add the
2524 output filter in the pre-connection phase instead of the
2525 post_read_request phase, which keeps us from trying to write an
2526 error page before we have a filter to write to the network.
2527 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2529 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2530 mmap can be used across multiple buckets (default_handler with
2531 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2532 the mmap itself can't be associated with the bucket.
2535 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2538 *) Radical surgery to improve mod_isapi support under Win32.
2539 Includes a number of newer ServerSupportFunction calls, support
2540 for ReadClient (in order to retrieve POSTs greater than 48KB),
2541 and general bug fixes to more reliably load ISAPI .dll's and
2542 prevent leaking handle resources. Note: There are still
2543 discrepancies between IIS's and Apache's ServerVariables, and
2544 async calls are still not supported. Additional warnings are
2545 logged to facilitate debugging of unsupported ISAPI calls.
2548 *) Add input filtering to Apache. The basic idea for the input
2549 filters is the same as the ideas for output filters. The biggest
2550 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2551 should be called, and the order of execution for the filter itself is
2552 different. When writing an output filter, a brigade is passed in,
2553 and filters operate directly on that brigade, when done, they call
2554 ap_pass_brigade. Input filters are the exact opposite. Because input
2555 is not a push operation, filters first call ap_get_brigade. When this
2556 function returns, the input filter will be left with a valid brigade.
2557 The input filter should then operate on the brigade, and return.
2560 *) Fix building on BSD/OS using its native make. The build system
2561 falls back to the BSD .include directive on that host platform.
2564 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2565 SHA1 and plaintext password encodings. Make feature tests a
2566 bit more flexible. [William Rowe]
2568 *) Charset translation: mod_charset_lite handles output content
2569 translation in a filter. mod_charset_lite no longer ignores
2570 subrequests. A bunch of cruft related to BUFF's support for
2571 translating request and response bodies was removed.
2574 *) Move the addition of the CORE filter to the post_read_request
2575 hook in http_core.c. This removes the need to add the filter in
2576 multiple places and allows for an SSL module to be added much
2577 simpler. [Ryan Bloom]
2579 *) Fix a security problem that affects certain configurations of
2580 mod_rewrite. If the result of a RewriteRule is a filename that
2581 contains expansion specifiers, especially regexp backreferences
2582 $0..$9 and %0..%9, then it may be possible for an attacker to
2583 access any file on the web server. [Tony Finch]
2585 *) Fix a bug where errors that are detected during early request parsing
2586 don't produce visible HTTP error messages at the browser, because
2587 the core_filter wasn't present. [Greg Ames]
2589 *) Provide apr_socklen_t as a portability aid.
2590 [Victor J. Orlikowski]
2592 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2593 as well as a comment arg to the add, adduser and update cmds.
2594 update allows the user to clear or preserve pw/groups/comment.
2595 Fixed a bug in dbmmanage that prevented the check option from
2596 parsing a password followed by :group... text. Corrected the
2597 seed calcualation for Win32 systems, and added -lsdbm support.
2600 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2603 *) Avoid a segfault when parsing .htaccess files. An
2604 uninitialized tree pointer was passed to ap_build_config().
2607 *) Change the way that inet_addr & inet_network are checked for
2608 in APR's configure process to allow BeOS BONE to correctly
2609 find them. With this change BeOS BONE now builds from source
2610 with no problems. [David Reid]
2612 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2613 the end of the parameters to execve() was stored in the wrong
2614 location, overlaying the storage beyond the newargs[] array and
2615 also passing uninitialized storage to execve(), which would
2616 sometimes fail with EFAULT. [Jeff Trawick]
2618 *) Fix a bug parsing configuration file containers. With a sequence
2619 like this in the config file
2621 <IfModule mod_kilroy.c>
2624 <IfModule mod_lovejoy.c>
2629 the second container would be terminated at the blank line due to
2630 sediment in the buffer from reading the prior </IfModule> and an
2631 error message would be generated for the real </IfModule> for the
2632 second container. Also due to this problem, any two characters
2633 could be used for "</" in the close of a container.
2636 *) ap_add_filter prototype changed to remove the ctx pointer. The
2637 pointer still remains in the filter structure, but it can not be
2638 a part of the ap_add_filter prototype. The reason is that when
2639 the core uses AddFilter to add a filter to the stack it doesn't
2640 know how to allocate the ctx pointer, or even how much memory should
2641 be allocated. The filters will have to be responsible for allocating
2642 the ctx memory when they need it.
2645 *) Add an AddFilter directive. This directive takes a list of filters
2646 that should be activated for the requested resource.
2649 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2650 some other platforms). [Jeff Trawick]
2652 *) Modify mod_include to be a filter. Currently, it has only been tested
2653 on actual files, but it should work for CGI scripts too.
2656 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2657 writes. apr_flush() for Unix: handle interrupted writes.
2660 *) NameVirtualHost can now take "*" as an argument instead of
2661 an IP address. This allows you to create a purely name-based
2662 virtual hosting server that does not have any IP addresses in
2663 the configuration file and which ignores the local address
2664 of any connections. PR #5595, PR #4455 [Tony Finch]
2666 *) Fix some compile warnings in mod_mmap_static.c
2667 [Mike Abbott <mja@sgi.com>]
2669 *) Fix chunking problem with CGI scripts. The general problem was that
2670 the CGI modules were adding an EOS bucket and then the core added an
2671 EOS bucket. The chunking filter finalizes the chunked response when it
2672 encounters an EOS bucket. Because two EOS buckets were sent, we
2673 finalized the response twice. The fix is to make sure we only send one
2674 EOS, by utilizing a flag in the request_rec.
2677 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2678 and Win32. Previously, the first read from an apr_file_t set up via
2679 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2681 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2682 bucket, instead of using BUFF's and ap_r*.
2685 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2686 [Mike Abbott <mja@sgi.com>]
2688 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2689 code to use APR file's directly instead of going through BUFFs.
2692 *) Fix compile break on some platforms for mod_mime_magic.c
2693 [John K. Sterling <sterling@covalent.net>]
2695 *) Fix merging of AddDefaultCharset directive.
2696 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2698 *) Minor revamp of the rlimit sections of code. We now test
2699 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2700 is now "available" even if the platform doesn't support
2701 the rlimit family (it's just a noop though). [Jim Jagielski]
2703 *) Migrate the pre-selection of which MPM to use for specific
2704 platforms to hints.m4, which contains (or should contain)
2705 all platform specific "hints". [Jim Jagielski]
2707 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2710 *) Add tables with non-string/binary values to APR.
2713 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2716 *) Update PCRE to version 3.2. [Ryan Bloom]
2718 *) Change the way buckets' destroy functions are called so that
2719 they can be more directly used when changing the type of a
2720 bucket in place. [Tony Finch]
2722 *) Add generic support for reference-counting the resources used by
2723 buckets, and alter the HEAP and MMAP buckets to use it. Change
2724 the way buckets are initialised to support changing the type of
2725 buckets in place, and use it when setting aside TRANSIENT buckets.
2726 Change the implementation of TRANSIENT buckets so that it can be
2727 mostly shared with IMMORTAL buckets, which are now implemented.
2730 Changes with Apache 2.0a6
2732 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2734 *) Add a chunking filter to Apache. This brings us one step closer
2735 to removing BUFF. [Ryan Bloom]
2737 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2738 added to the stack is the last filter to be called. [Ryan Bloom]
2740 *) Apache 2.0 has been completely documented using Scandoc. The
2741 docs can be generated by running 'make docs'. [Ryan Bloom]
2743 *) Add filtered I/O to Apache. This is based on bucket brigades,
2744 Currently the buckets still use BUFF under the covers, but that
2745 should change quickly. The only currently written filter is the
2746 core filter which just calls ap_bwrite. [The Apache Group]
2748 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2749 built with thread support. [Jeff Trawick]
2751 *) Abort configuration if --with-layout was specified and there's
2752 no layout definition file. [Ken Coar]
2754 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2756 *) Add support for extension methods for the Allow response header
2757 field, and an API routine for accessing r->allowed and the
2758 list of extension methods in a unified manner. [Ken Coar]
2760 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2761 [Rob Simonson <simo@us.ibm.com>]
2763 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2764 APACHE_XLATE builds. [Jeff Trawick]
2766 *) A configuration file parsing problem was fixed. When the
2767 configuration file started with an IfModule/IfDefine container,
2768 only the last statement in the container would be retained.
2771 Changes with Apache 2.0a5
2773 *) Perchild is serving pages after passing them to different child
2774 processes. There are still a lot of bugs, but this does work. I
2775 have made requests against the same installation of Apache, and had
2776 different servers use different user IDs to serve the responses.
2777 This change moves to using socketpair instead of an AF_UNIX socket.
2780 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2781 It can't seem to pass between child processes yet, but I think we
2782 are closer now than before. This moves us back to using Unix
2783 Domain Sockets. [Ryan Bloom]
2785 *) libapr functions and types renamed with apr_ prefix.
2786 #include "apr_compat.h" for 1.3.x backwards compat
2789 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2790 return the right information on the local socket address.
2791 [Gregory Nicholls <gnicholls@level8.com>]
2793 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2794 [Gregory Nicholls <gnicholls@level8.com>]
2796 *) Add an option to not detach from the controlling terminal without
2797 going into single process mode. This allows for much easier
2798 debugging of the process startup code. [Ryan Bloom]
2800 *) ab: don't use perror() to report the failure of an APR function.
2803 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2804 scoreboard on graceful restarts.
2807 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2808 An invalid ap_proc_t was passed to ap_create_process().
2811 *) Allow modules to register filters. Those filters are still
2812 never called, but this is a step in the right direction.
2813 [Ryan Bloom and Greg Stein]
2815 *) Register the mod_cgid daemon process for cleanup so that it is
2816 killed at termination if it does not die when the parent gets
2817 SIGTERM. This change is to fix occasional problems where the
2818 process stays around. Bugs in similar logic in mod_rewrite and
2819 mod_include were also fixed. [Jeff Trawick]
2821 *) Fix a bug in the time handling. Basically, we were imploding a time
2822 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2823 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2824 uses those two fields to adjust the time value. Because of the HTTP
2825 spec, both of those values can be zero'ed out safely. This fixes
2826 the bug correctly. [Ryan Bloom]
2828 *) Fix a couple of place in the Windows code where the wrong error
2829 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2831 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2833 *) Added the APR_EOL_STR macro for platform dependent differences in
2834 logfiles and other raw text (such as all APR files). Fixes logfiles
2835 not terminated with cr/lf sequences in Win32. [William Rowe]
2837 *) Move all strings functions in APR to src/lib/apr/strings and create
2838 apr_strings.h for the prototypes. [Ryan Bloom]
2840 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2841 to repeat the syscall until we stop getting EINTR. I noticed a
2842 related problem at termination (SIGTERM) on FreeBSD when using
2843 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2844 implementation work properly with child init. Previously, ap_lock()
2845 was essentially a no-op because all children were using different
2846 locks and thus nobody ever blocked. [Jeff Trawick]
2848 *) The htdocs/ tree has been moved out of the CVS source tree into
2849 a separate area for easier development. This has NO EFFECT on
2850 end-users or Apache installations. [Ken Coar]
2852 *) Integrate the mod_dav module for WebDAV protocol handling. This
2853 adds the dav and dav_fs modules, the SDBM library, and additional
2854 XML handling utilities. [Greg Stein]
2856 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2859 *) Update the lib/expat-lite/ library (bring forward changes from
2860 the Apache 1.3 repository). [Greg Stein]
2862 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2863 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2865 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2866 machines where sendfile is detected, but nobody has written ap_sendfile.
2867 [Dave Hill <ddhill@zk3.dec.com>]
2869 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2871 *) ab would start up more connections than needed, then quit when the
2872 desired number were finished. Also fixed a logic error involving
2873 ab keepalives. [Victor J. Orlikowski]
2875 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2876 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2877 timeouts (i.e, if a timeout was specified, the pipe reverted to
2878 a full blocking pipe). Now the behaviour is more in line with
2879 Unix non-blocking pipes.
2882 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2883 cache open file handles along with accept socket reuse enables
2884 Apache 2.0 to serve non-keepalive requests for static files at
2885 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2886 and Apache 2.0 will serve almost 1200 rps on my system).
2889 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2890 supports two config directives, mmapfile (same behavious as
2891 mod_mmap_static) and cachefile. Use the cachefile directive
2892 to cache open file handles. This directive only works on systems
2893 that have implemented the ap_sendfile API. cachefile works today
2894 on Windows NT, but has not been tested on any flavors of Unix.
2897 *) Cleanup the configuration. With the last few changes the
2898 configuration process automatically:
2899 inherits information about how to build from APR. Allowing
2900 APR to inform Apache that it should or should not use -ldl
2902 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2903 based on the threading model
2905 Apache calls APR's configure process before finishing it's
2906 configuration processing, allowing for more information flow
2911 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2912 with non-zero argument makes the socket non-blocking. BeOS and
2913 OS/2 already worked this way. [Jeff Trawick]
2915 *) ap_close() now calls ap_flush() for buffered files, so write
2916 operations work a whole lot better on buffered files.
2919 *) Fix error messages issued from MPMs which explain where to change
2920 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2923 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2924 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2925 now the way that the blocking state of a pipe is manipulated.
2926 ap_block_pipe() is gone. [Jeff Trawick]
2928 *) Correct the problem where the only local host name that the IP stack
2929 can discover are 'undotted' private names. If no fully qualified
2930 domain name can be identified, the default ServerName will be set to
2931 the machine's IP address string. A warning is always provided if the
2932 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2934 *) Repair problems with config file processing which caused segfault
2935 at init when virtual hosts were defined and which caused ServerName to
2936 be ignored when there was no valid DNS setup. [Jeff Trawick]
2938 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2940 *) Add ap_sendfile implementation for AIX
2941 [Victor J. Orlikowski]
2943 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2944 apr_network_io.h, and apr_thread_proc.h.
2945 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2947 *) Bring the allocation and pool debugging code back into a working
2948 state. This will need to be tested as so far it's only been used on
2951 *) Change configuration command setup to be properly typesafe when in
2952 maintainer mode. Note that this requires a compiler that can initialise
2953 unions. [Ben Laurie]
2955 *) Turn on buffering for config file reads. Part of this was to
2956 repair buffered I/O support in Unix and implement buffered
2957 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2959 *) Win32: Fix problem where UTC offset was not being set correctly
2960 in the access log. Problem reported on news group by Jerry Baker.
2963 *) Fix segfault when reporting this type of syntax error:
2964 "</container> without matching <container> section", where
2965 container is VirtualHost or Directory or whatever.
2968 *) Prevent the source code for CGIs from being revealed when using
2969 mod_vhost_alias and the CGI directory is under the document root
2970 and a user makes a request like http://www.example.com//cgi-bin/cgi
2971 as reported in <news:960999105.344321@ernani.logica.co.uk>
2974 *) Add support for the new Beos NetwOrking Environment (BONE)
2977 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2978 final input char is incomplete; ap_bwrite_xlate() now handles
2979 incomplete final input chars. [Jeff Trawick]
2981 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2982 that a bhalfduplex call occurs before logging or else DNS and
2983 such can delay the last packet of the response. [Dean Gaudet]
2985 *) Some syscall reduction in APR on unix -- don't seek when setting
2986 up an mmap; and don't fcntl() more than once per socket.
2989 *) When mod_cgid is started as root, the cgi daemon now switches
2990 to the configured User/Group (like other httpd processes)
2991 instead of continuing as root. [Jeff Trawick]
2993 *) The prefork MPM now uses an APR lock for the accept() mutex.
2994 It has not been getting a lock at all recently. httpd -V now
2995 displays APR's selection of the lock mechanism instead of the
2996 symbols previously respected by prefork. [Jeff Trawick]
2998 *) Change the mmap() feature test to check only for existence.
2999 The previous check required features not used by Apache.
3002 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
3003 sometimes mangled. The len parm to accept() was not
3004 initialized, leading sometimes to an endless loop of failed
3005 accept() calls on OS/390 and anywhere else that failed the call
3006 if the len was negative. Use <sys/un.h> for struct sockaddr_un
3007 instead of declaring it ourselves to fix a compilation problem
3008 on Solaris. [Jeff Trawick]
3010 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
3012 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
3014 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
3016 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
3017 initialization if ALLOC_DEBUG is defined; no known symptom
3018 otherwise. [Jeff Trawick]
3020 *) Fix typo in configure script when checking for mod_so. bash
3021 doesn't seem to have a problem but /bin/sh on Solaris does.
3022 Symptom: "./configure: test: unknown operator =="
3025 *) Rebind the Win32 NT and 9x services control into the MPM.
3026 All console, WinNT SCM and Win9x pseudo-service control code is
3027 now wrapped within the WinNT MPM.
3030 *) Make a copy of getenv("PATH") before storing for later use. Some
3031 getenv() implementations use the same storage for successive calls.
3032 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
3034 *) Server Tokens work in 2.0 again. This also propogates the change
3035 to allow just the product name in the server string using
3039 Changes with Apache 2.0a4
3041 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
3042 won't need to call it. [Greg Ames, Jeff Trawick]
3044 *) Move pre_config hook call to between configuration read and config
3045 tree walk. This allows all modules to implement pre_config hooks
3046 and know that they will be called at an appropriate time.
3049 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
3052 *) Add pre-config hooks back to all modules.
3055 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
3056 ContentDigest enabled and we can't/don't mmap the file.
3059 *) We now report the correct line number for syntax errors in config
3060 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
3062 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
3063 related bugs, and changed shmem/locking to use apr API. Shared-mem
3064 is currently disabled, however, because of problems with graceful
3065 restarts. [Ronald Tschalär]
3067 *) Fix corruption of IFS variable in --with-module= handling.
3068 Depending on the user's shell or customization thereof, there
3069 would be errors generating ap_config_auto.h later in the configure
3070 procedure. [Jeff Trawick]
3072 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
3073 isn't used (as in 1.3), except that on Unix it is now logged via
3074 ap_log_rerror() instead of by the child having STDERR_FILENO refer
3075 to the error log. [Greg Ames, Jeff Trawick]
3077 *) Add '-D' argument processing for run time configuration defines.
3080 *) Organize http_main.c as independent code, such that no code or
3081 global data is exported from it. WIN32 will dynamically link it
3082 to the server core, so this will prevent mutual dependency.
3085 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
3086 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
3089 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
3090 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
3092 *) Add mod_charset_lite for configuring character set translation.
3095 *) Add '-n' option to htpasswd to make it print its user:pw record
3096 on stdout rather than having to frob a text file. [Ken Coar]
3098 *) Fix saferead. Basically, we flush the output buffer if a read on the
3102 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
3103 a conversion is single-byte only. [Jeff Trawick]
3105 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
3106 the BeOS 5.0 documentation says that shutdown doesn't work yet.
3109 *) Fix some minor errors where pid was being manipulated as an int
3110 instead of the portable pid_t. [Roy Fielding]
3112 *) Fix some error log prints that were printing the pointer to a
3113 structure rather than the pid within the structure.
3114 [Jeff Trawick, Roy Fielding]
3116 *) ab: Fix a command-line processing bug; track bad headers in
3117 err_response; support reading headers up to 2K.
3118 [Ask Bjoern Hansen <ask@valueclick.com>]
3120 *) Fix ap_resolve_env() so that it handles new function added in a prior
3121 alpha (see "Added the capability to do ${ENVVAR} constructs in the
3122 config file.") as well as the constructs used by mod_rewrite.
3123 [Paul Reder <rederpj@raleigh.ibm.com>]
3125 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
3127 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
3128 APR to perform translation, instead of accessing the hard-coded tables
3129 in 1.3's ebcdic.c. [Jeff Trawick]
3131 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
3134 *) Add the ability to hook into the config file reading phase. Basically
3135 if a directive is specified EXEC_ON_READ, then when that directive is
3136 read from the config file, the assocaited function is executed. This
3137 should only be used for those directives that must muck with HOW the
3138 server INTERPRETS the config. This should not be used for directives
3139 that re-order or replace items in the config tree. Those changes should
3140 be made in the pre-config step.
3143 *) Add mod_example to the build system.
3146 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
3147 byte character sets. [Jeff Trawick]
3149 *) Pick up various EBCDIC fixes from 1.3 (from Martin
3150 Kraemer and Oliver Reh originally according to the change log).
3153 *) Fix a couple of problems in RFC1413 support (controlled by the
3154 IdentityCheck directive). Apache did not build the request string
3155 properly and more importantly Apache would loop forever if the
3156 would-be ident server dropped the connection before sending a
3157 properly terminated response. [Jeff Trawick]
3159 *) apxs works in 2.0.
3162 *) Reliable piped logs work in 2.0.
3165 *) Introduce a hash table implementation into APR to be used for
3166 replacing tables and other random data structures in Apache.
3169 *) Add some more error reporting to htpasswd in the case of problems
3170 generating or accessing the temporary file. Also, pass in a
3171 buffer if the implementation knows how to use it (i.e., if L_tmpnam
3172 is defined). [Ken Coar]
3174 *) Configure creates config.nice now containing your configure
3175 options. Syntax: ./config.nice [--more-options]
3178 *) Fix various return code problems in APR on Win32. For most of
3179 these, APR was returning APR_EEXIST instead of GetLastError()/
3180 WSAGetLastError(). [Jeff Trawick]
3182 *) Make piped logs work again in version 2.0
3185 *) Add VPATH support to UNIX build system of Apache and APR.
3188 *) Fix ap_tokenize_to_argv to respect the const arguments that are
3192 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
3193 Patch submitted to author.
3196 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
3197 /sbin in PATH on FreeBSD (all submitted to rse previously)
3200 *) Fix building Pthread-based MPMs on OpenBSD
3201 [Sascha Schumann] PR#26
3203 *) Fix ap_readdir() problem on systems where d_name[] field in
3204 struct dirent is declared with only one byte. (This problem only
3205 affected multithreaded builds.) This caused a segfault during
3206 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3207 least). [Jeff Trawick]
3209 *) Fix some make-portability problems on at least Tru64, Irix
3211 [Sascha Schumann] PR#18, PR#39
3213 *) Add ap_sigwait() to support old-style sigwait() on systems
3214 like OS/390 and UnixWare.
3217 *) Add POSIX-thread flags for more platforms.
3220 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3221 (on Unix, at least) to handle resolver errors. Fix a bug in
3222 the definition of APR_ENOMEM so that ap_strerror() can spit
3223 out the correct error message for it.
3226 Changes with Apache 2.0a3
3228 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3231 *) API: *HOOK* macros now have an AP_ prefix
3234 *) Win32: Eliminate redundant calls to initialize winsock.
3235 [Tim Costello <timcostello@ozemail.com.au>]
3237 *) Fix bugs initializing ungetchar for pipes.
3238 [Chia-liang Kao <clkao@CirX.ORG>]
3240 *) The ab program in the src/support directory is now portable using
3244 *) Support directory is being compiled when the server is built
3247 *) The configure option --with-program-name has been added to allow
3248 developers to rename the executable at configure time. This also
3249 changes the name of the config files to match the executable's name.
3252 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3253 containing version numbers. [Martin Pool]
3255 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3256 Unix; access_log and error_log now created with these perms; non-
3257 Unix is unaffected [Jeff Trawick]
3259 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3260 Replaced more magic numbers with MD5_DIGESTSIZE.
3261 [William Rowe, Roy Fielding]
3263 *) Win32: Get mod_auth_digest compiling and added to the Windows
3264 build environment. Not tested and I'd be suprised if it
3265 actually works. [Bill Stoddard]
3267 *) Revamp the Win32 make environment. Makefiles have been removed and
3268 Apache.dsw created to bring together all the pieces. Create new file
3269 os/win32/BaseAddr.ref to define module base addresses (to prevent
3270 dll relocation at start-up).
3271 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3273 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3274 of the \015, \012, and \015\012 constants with macros.
3275 [Greg Ames <gregames@us.ibm.com>]
3277 *) Add ap_xlate_open() et al for translation of text between different
3278 character sets. The initial implementation requires iconv().
3281 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3282 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3284 *) CGI output is being timed out now.
3287 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3288 is used by the new apr file. There is no reason to create a new file
3289 with the same lifetime as the original file.
3292 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3293 module base addresses. This will help shooting seg faults
3294 in the field. [William Rowe <wrowe@lnd.com>]
3296 *) Update Apache on Windows documentation. Add new document
3297 describing how to compile Apache on Windows.
3298 [William Rowe <wrowe@lnd.com>]
3300 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3301 microseconds instead of seconds. Some storage leaks and other
3302 minor bugs in related code were fixed. [Jeff Trawick]
3304 *) Win32: First cut at getting mod_isapi working under 2.0
3305 [William Rowe <wrowe@lnd.com>]
3307 *) First stab at getting mod_auth_digest working under 2.0
3308 quick change summary:
3309 - moved the random byte generation (ap_generate_random_bytes) into APR
3310 - now uses ap_time_t
3311 - compiles and runs on linux
3313 [Brian Martin <bmartin@penguincomputing.com>]
3315 *) Win32: Move the space stripping of physical service names
3316 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3317 unresolved symbol. Add dependency checking to the
3318 CreateService call to ensure TCPIP and AFP (winsock) is started
3320 [William Rowe <wrowe@lnd.com>]
3322 *) Win32: Add code to perform latebinding on functions that may
3323 not exist on all levels of Windows where Apache runs. This
3324 is needed to allow Apache to start-up on Win95/98. All calls
3325 to non portable functions should be protected with
3326 ap_oslevel checks to prevent runtime segfaults.
3327 [William Rowe <wrowe@lnd.com>]
3329 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3331 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3333 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3334 This addresses PR 1623. Still need to address timing out runaway
3335 CGI scripts. [Bill Stoddard]
3337 *) Win32: Make ap_stat Windows 95/98 friendly
3338 [William Rowe <wrowe@lnd.com>]
3340 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3341 always fail. Need to initialise the dwOSVersionInfoSize member of the
3342 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3345 The patch also enhances ap_get_oslevel (and the associated enum) to
3346 handle selected service packs for NT4, and adds recognition for
3347 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3348 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3349 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3351 *) Get mod_rewrite building and running, and mod_status building for Win NT
3352 [Allan Edwards <ake@raleigh.ibm.com>]
3354 *) Patch to port mod_auth_db to the 2.0 api and also to support
3355 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3356 2.7.7. It should work with version 1 as well but I haven't tested it.
3357 [Brian Martin <bmartin@penguincomputing.com>]
3359 *) Get APR DSO code working under Windows. Includes cross platform
3361 [Tim.Costello@BTFinancialgroup.com]
3363 *) Fix some of the Windows APR time functions.
3366 *) FAQ changes related to tidying up historical documents on the web site.
3367 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3369 *) Move Windows DSO code into APR.
3372 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3373 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3374 at build time. At this point, the server will not compile on Windows because
3375 of the recent DSO commits. Fixing those next.
3376 [Bill Rowe & Bill Stoddard]
3378 *) Added error checking for file I/O APR routines.
3379 [Jon Travis <jtravis@covalent.net>]
3381 *) APR: Don't use the values of resolver error codes for the
3382 corresponding APR error codes. On Unix and Win32, return the
3383 proper APR error code after a resolver error. [Jeff Trawick]
3385 Changes with Apache 2.0a2
3387 *) Renamed the executable back to httpd on all platforms other
3391 *) Allow BeOS to survive restarts, log properly and a few
3392 small things it had problems with due to the way it setup
3393 users and groups. [David Reid]
3395 *) Get mod_rewrite working with APR locks
3396 [Paul Reder <rederpj@raleigh.ibm.com>]
3398 *) Actually remove the sempahore when the lock cleanup routine
3399 is called on BeOS. [David Reid]
3401 *) Clear hook registrations between reads of the config file.
3402 When DSOs are unloaded and re-loaded the old hook pointers may
3403 no longer be valid. This fix eliminates potential segfaults.
3404 [Allan Edwards <ake@raleigh.ibm.com>]
3406 *) Fix a problem with Sigfunc not being defined or bypassed
3407 if sigaction() wasn't found. [Jim Jagielski]
3409 *) Fix the locking mechanism on BSD variants. They now use fcntl
3410 locks. This allows the server to start and serve pages.
3413 *) First cut at getting the Win32 installer to work
3414 [William Rowe <wrowe@lnd.com>]
3416 *) Get htpasswd compiling under Windows
3417 [William Rowe <wrowe@lnd.com>]
3419 *) Change the log message for a bind() failure to show the
3420 interface and port number. [Jeff Trawick]
3422 *) Import the documentation from 1.3.12 and bring parts of it
3423 up-to-date with respect to the changes that have occurred
3427 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3428 now logged correctly on BeOS.
3431 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3432 Makefile.win includes the same user interface as the old
3434 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3436 *) Win32 exec now uses COMSPEC environment string for command
3437 shell path resolution.
3438 [William Rowe <wrowe@lnd.com>] PR#3715
3440 *) Win32: ap_connect() was not returning correct error condition
3442 [Allen Prescott <allen@clanprescott.com>]
3444 *) Win32: ap_open() was broken on Win9x because an NT-specific
3445 flag was passed to CreateFile. ap_puts() added an unnecessary
3447 [Jeff Trawick <trawick@us.ibm.com>]
3449 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3450 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3451 confusing ee/et name and made all extensions language/dialect
3452 rather than country reflecting. Changed example files to
3453 explicit reflect the ISO charset and added a few common
3454 ones to the example config [dirkx]
3456 *) Extend external module capability. To use this, you call
3457 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3460 *) Backported the various "default charset" fixes from 1.3.12,
3461 including the AddDefaultCharset directive. [Jim Jagielski]
3463 *) Added the capability to do ${ENVVAR} constructs in the
3464 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3465 it does this on a line by line basis; i.e. if the envvar
3466 expands to something with spaces you have to protect it
3467 by adding quotes around it (Unless of course you expect it
3468 to contains more than one argument. Alternatively you
3469 can compile it on a per token basis; which is what people
3470 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3471 hampers fancier hacks.
3472 [Dirk-Willem van Gulik]
3474 *) Changed the 'ErrorDocument' syntax in that it NO longer
3475 supports the asymetric
3477 ErrorDocument 301 "Some message
3479 Note the opening " quote, without a closing quote. It now
3480 has either the following syntaxes
3482 ErrorDocument XXX /local/uri
3483 ErrorDocument XXX http://valid/url
3484 ErrorDocument XXX "Some Message"
3486 The recognition heuristic is: if it has a space it
3487 is a message. If it has no spaces and starts with a /
3488 or is a valid URL then treat it that way. Otherwise it
3489 is assumed to be a message.
3491 This breaks backward compatibility but makes live a hell
3492 of a lot easier for GUI's and config file parsers.
3493 [Dirk-Willem van Gulik]
3495 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3496 syntax into a 'on' or 'off' syntax. As it currently is the
3497 only non nesting token which uses NO_ARGS and thus is an
3498 absolute pain for any config interface automation. This
3499 breaks backward compatibility. [Dirk-Willem van Gulik]
3501 *) Add ability to add external modules to the build process. This is
3502 done with --with-module=/path/to/module. Modules can only be added
3503 as static modules at this point.
3506 Changes with Apache 2.0a1
3508 *) Fix FreeBSD 3.3 core dump.
3509 Basically, ap_initialize() needs to get called before
3510 create_process(), since create_process() passes op_on structure
3511 to semop() to get a lock, but op_on isn't initialized until
3512 ap_initialize() calls setup_lock(). Here is a slight
3513 rearrangement to main() which calls ap_initialize() earlier...
3514 [Jeff Trawick <trawick@us.ibm.com>]
3516 *) Enable Apache to use sendfile/TransmitFile API
3517 [Bill Stoddard, David Reid, Paul Reder]
3519 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3523 *) Make file I/O and network I/O writev/sendv APIs consistent.
3524 Eliminate use of ap_iovec_t and use Posix struct iovec.
3525 Use seperate variable on ap_writev to set the number of iovecs
3526 passed in and number of bytes written.
3529 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3530 with ap_create_file_iol(). ap_create_file_iol() requires that
3531 the file be opened prior to the call using ap_open().
3534 *) Port mod_include and mod_cgi to 2.0
3535 [Paul Reder, Bill Stoddard]
3537 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3538 bytes_read/bytes_written is always valid (never -1). Plus
3539 some fixes to buff.c to correct problems introduced by the
3540 errno => ap_status_t changes a while back. Plus a fix to
3541 chunked encoding introduced right at the beginning of 2.0.
3544 *) Revamped UNIX build system to use autoconf and libtool.
3545 [Manoj Kasichainula, Sascha Schumann]
3547 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3549 *) More rigorous checking of Host: headers to fix security problems
3550 with mass name-based virtual hosting (whether using mod_rewrite
3551 or mod_vhost_alias).
3552 [Ben Hyde, Tony Finch]
3554 *) Add back support for UseCanonicalName in <Directory> containers.
3555 [Manoj Kasichainula]
3557 *) Added APLOG_STARTUP log type. This allows us to write an error
3558 message without any of the date and time information. As a part
3559 of this change, I also removed all of the calls to fprintf(stderr
3560 and replaced them with calls to ap_log_error using APLOG_STARTUP
3561 writing to stderr is no longer portable, because we don't direct
3562 stderr to the error log on all platforms.
3565 *) Convert error logging functions to take errno as an argument.
3566 This makes our error logs more portable, because some Windows API's
3567 don't set errno. This change allows us to still output a valid
3568 message on all of our platforms.
3571 *) mod_mime_magic runs in 2.0-dev now.
3572 [Paul Reder <rederpj@raleigh.ibm.com>]
3574 *) sendfile has been added to APR.
3575 [John Zedlewski <zedlwski@Princeton.EDU>]
3577 *) buff.c has been converted to no longer use errno.
3578 [Manoj Kasichainula]
3580 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3581 interface adaption to APR functions did it. [Martin Kraemer]
3583 *) Support DSOs properly on 32-bit HP-UX 11.0
3584 [Dilip Khandekar <dilip@cup.hp.com>]
3586 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3587 [Ralf S. Engelschall]
3589 *) Cleaned APR build environment integration and bootstrap APR
3590 automatically for developers from src/Configure.
3591 [Ralf S. Engelschall]
3593 *) Fixed building of src/support/htpasswd.c
3594 [Ralf S. Engelschall]
3596 *) When generating the Location: header, mod_speling forgot
3597 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3600 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3602 *) Change all pools to APR contexts. This is the first step to
3603 incorporating APR into Apache. [Ryan Bloom]
3605 *) Move "handler not found" warning message to below the check
3606 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3607 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3609 *) Support line-continuation feature in config.option file and
3610 allow the loading of multiple option sections at once via
3611 ``--with-option=<section1>,<section2>,...''
3612 [Ralf S. Engelschall]
3614 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3616 Changes with Apache MPM
3618 *) Use asynchronous AcceptEx() and a completion port to accept and
3619 dispatch connections to threads in Windows NT/2000.
3622 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3625 *) Implement the APACI --with-option facility
3626 (per default used the config.option file).
3627 [Ralf S. Engelschall]
3629 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3631 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3632 Replace pre_connection module call with a register_hook call and
3633 implement pre_connection as a hook. The intent is that these hooks will
3634 be extended to allow Apache to be multi-protocol, and also to allow the
3635 calling order to be specified on a per-hook/per-module basis.
3638 *) Implement mpm_* methods as "modules". Each method gets its own
3639 subdir in src/modules (eg: src/modules/prefork). Selection
3640 of method uses Rule MPM_METHOD. [Jim Jagielski]
3642 *) Port the hybrid server from the apache-apr repository as
3643 mpm_mpmt_pthread. [Manoj Kasichainula]
3645 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3646 amongst the unix MPMs.
3648 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3649 signal handling for the new world order. [Dean Gaudet]
3651 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3652 of alloc.c for now. [Dean Gaudet]
3654 *) Handle partial large writes correctly. [Ben Laurie]
3656 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3657 based on IP/port. [Ben Laurie]
3659 *) Port a bunch of modules to the new module structure.
3660 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3662 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3664 *) Basic restructuring to introduce the MPM concept; includes various
3665 changes to the module API... better described by
3666 docs/initial_blurb.txt. [Dean Gaudet]
3668 Changes with Apache pthreads
3670 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3671 buff operations (generally over a network).
3672 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3674 *) Created http_accept abstraction. Added 4 new functions (not exported):
3675 init_accept(), begin_accepting_requests(), get_request(),
3676 stop_accepting_requests() [Bill Stoddard]
3678 *) Fix to ap_rprintf call that allows mod_info to work properly.
3679 [James Morris <jmorris@intercode.com.au>]
3681 *) user and ap_auth_type fields were moved from connection_rec to
3682 request_rec. [Ryan Bloom]
3684 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3685 needed in a threaded server.
3687 *) Initial pthread implementation from from Dean's apache-nspr code.
3688 [Bill Stoddard, Ryan Bloom]
3691 Changes with Apache 1.3.9
3693 *) Remove bogus error message when a redirect doesn't set Location.
3694 Instead, use an empty string to avoid coredump if the error message
3695 was supposed to include a location. [Roy Fielding]
3697 *) Don't allow configure to include mod_auth_digest unless it is
3698 explicitly requested, even if the user asked for all modules.
3701 *) Translate module names to dll names for OS/2 so that they are no more
3702 than 8 characters long and have an extension of "dll" instead of "so".
3705 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3706 Fix test-compile check to check for randbyte instead of trand32.
3707 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3708 and tweak to make Amaya happier. [Ronald Tschalär]
3710 *) Ensure that the installed expat include files are world readable,
3711 just like the other header files. [Martin Kraemer]
3713 *) Fixed generated AddModule adjustments in APACI's `configure' script
3714 in order to allow (new) modules like mod_vhost_alias to be handled
3715 correctly (which was touched by the adjustments for mod_alias).
3716 [Ralf S. Engelschall]
3718 *) For binary builds, add -R flag to apachectl to work around the lack of
3719 an absolute path to the ./libexec directory where the libhttp.ep file
3720 is needed for SHARED_CORE architectures. [Randy Terbush]
3722 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3723 problem observed by some Win95/98 users where they get CGI script
3724 output sent to the console. [Bill Stoddard]
3726 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3727 routines are now called ap_base64* and are 'plain' (i.e., no
3728 pool access or anything clever). Inside util.c the routines acting
3729 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3730 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3731 now but deprecated. [dirkx]
3733 *) Clean up the base64 and SHA1 additions and make sure they are
3734 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3735 files. [Roy Fielding]
3737 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3738 checking. Allow compiling on VS 6.0. [Randy Terbush]
3740 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3742 *) Use TestCompile to search for the truerand library (rather than blindly
3743 assuming its existence). If it is not found, complain (but do not
3744 exit - yet). [Martin Kraemer]
3746 *) We forgot to add the new exported function names to
3747 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3749 *) Add description of -T command-line option to usage().
3750 [Ralf S. Engelschall]
3752 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3753 searched only AFTER libap has been searched, because libap needs
3754 some symbols from libos. [Martin Kraemer]
3756 *) Fix conflict with original mod_digest related to the symbol of the
3757 module dispatch list (which has to be unique for DSO and follow the
3758 usual conventions for the installation procedure).
3759 [Ralf S. Engelschall]
3761 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3762 for other platforms as well. [Martin Kraemer]
3764 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3765 types by AP_LONG and replace reference to renamed variable 'ubuf'
3766 by 'buffer'. [Martin Kraemer]
3768 Changes with Apache 1.3.8 [not released]
3770 *) Flush the output buffer immediately after sending an error or redirect
3771 response, since the result may be needed by the client to abort a
3772 long data transfer or restart a series of pipelined requests.
3773 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3775 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3776 [Ian Turner <iant@sequent.com>] PR#4735
3778 *) Local struct mmap in http_core.c conflicted with system structure
3779 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3781 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3782 [Ronald Tschalär <ronald@innovation.ch>]
3784 *) Fix a memory leak where the module counts were getting messed
3785 up across restarts. [David Harris <dharris@drh.net>]
3787 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3788 properly in mod_access.
3789 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3791 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3792 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3794 *) PORT: Support for compaq/tandem/com.
3795 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3797 *) Added SHA1 password encryption support to easy migration from
3798 Netscape servers. See support/SHA1 for more information.
3799 Caused the separation of ap_md5.c into md5, sha1 and a general
3800 ap_checkpass.c with just a validate_passwd routine. Added a
3801 couple of flags to support/htpasswd. Some reuse of the to64()
3802 function; hence renamed to ap_to64().
3803 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3805 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3806 with ASCII/EBCDIC conversions in "ident" query.
3807 [David McCreedy <McCreedy@us.ibm.com>]
3809 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3810 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3811 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3813 *) Fix SIGSEGV on some systems because the Vary fix below included
3814 a call to table_do with a variable argument list that was not
3815 NULL terminated. Replaced with better implementation. [Roy Fielding]
3817 Changes with Apache 1.3.7 [not released]
3819 *) The "Vary" response header field is now sanitised right before
3820 the header is sent back to the client. Multiple "Vary" fields
3821 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3822 "Vary: host, negotiate, host, accept-language") are reduced to
3823 single instances. This is a better solution than the force-no-vary
3824 one (which is still valid for clients that can't cope with Vary
3825 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3827 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3829 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3830 least on Linux and FreeBSD for now.
3833 *) Win32: More apache -k restart work. Restarts are now honored
3834 immediately and connections in the listen queue are -not- lost.
3835 This is made possible by the use of the WSADuplicateSocket()
3836 call. The listeners are opened in the parent, duplicated, then
3837 the duplicates are passed to the child. The original listen sockets
3838 are not closed by the parent across a restart, thus the listen queue
3840 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3842 *) Fix handling of case when a client has sent "Expect: 100-continue"
3843 and we are going to respond with an error, but get stuck waiting to
3844 discard the body in the pointless hope of preserving the connection.
3845 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3847 *) Fix 'configure' to work correctly with SysV-based versions of
3848 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3850 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3851 built-in values. Add "-e" option which works like -i but doesn't
3852 install the DSO; useful for editing httpd.conf with apxs. Fix
3853 editing code so that multiple invocations of apxs -a will not
3854 create duplicate LoadModule/AddModule entries; apxs can now be
3855 used to re- enable/disable a module. [Wilfredo Sanchez]
3857 *) Win32: Update the server to use Winsock 2. Specifically, link with
3858 ws2_32.lib rather than wsock32.lib. This gives us access to
3859 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3860 Win 95 users may need to update their TCP/IP stack to pick up
3861 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3862 [Bill Stoddard stoddard@raleigh.ibm.com]
3864 *) Win32: Redirect CGI script stderr (script debug info) into the
3865 error.log when CGI scripts fail. This makes Apache on Win32
3866 behave more like Unix.
3867 [Bill Stoddard stoddard@raleigh.ibm.com]
3869 *) Fixed `httpd' usage display: -D was missing.
3870 [Ralf S. Engelschall] PR#4614
3872 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3873 [Ralf S. Engelschall] PR#4561, PR#4562
3875 *) OS/2: Fix problem with accept lock semaphores where server would die with
3876 "OS2SEM: Error 105 getting accept lock. Exiting!"
3877 [Brian Havard] PR#4505
3879 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3880 [Randy Terbush <randy@covalent.net>]
3882 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3883 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3885 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3886 command potentially _is_ GCC. [Ralf S. Engelschall]
3888 *) Fix apxs build issues on AIX
3889 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3891 *) DocumentRoot Checking: Under previous versions, when Apache
3892 first started up, it used to do a stat of each DocumentRoot to
3893 see if it existed and was a directory. If not, then an error
3894 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3895 does not exist, you will get error messages in error_log. If
3896 the '-t' command line option is used (to check the configuration)
3897 the check of DocumentRoot IS performed. An additional command
3898 line option, '-T', has been added if you want to avoid the
3899 DocumentRoot check even when checking the configuration.
3902 *) Win32: The query switch "apache -S" didn't exit after showing the
3903 vhost settings. That was inconsistent with the other query functions.
3904 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3906 *) Win32: Changed behaviour of apache -k restart.
3907 Previously, the server would drain all connections in the stack's
3908 listen queue before honoring the restart. On a busy server, this
3909 could take hours. Now, a restart is honored almost immediately.
3910 All connections in Apache's queues are handled but connections in
3911 the stack's listen queue are discarded. Restart triggered by
3912 MaxRequestPerChild is unchanged.
3913 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3915 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3916 the accept loop. Good for a 5% performance boost. Cleaned up
3917 parent/child process management code.
3918 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3920 *) Added ceiling on file size for memory mapped files.
3921 [John Giannandrea <jg@meer.net>] PR#4122
3923 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3924 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3925 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3927 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3928 use this at least for Expat. [Ralf S. Engelschall]
3930 *) Allow .module files to specify libraries with Lib:.
3933 *) Allow SetEnvIf[NoCase] to test environment variables as well
3934 as header fields and request attributes. [Ken Coar]
3936 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3937 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3939 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3940 never accepted into any standard, and it opens up certain DoS
3941 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3943 *) TestCompile updated. We can now run programs and output the
3944 results during the Configure process. [ Jim Jagielski]
3946 *) The source is now quad (long long) aware as needed. Specifically,
3947 the Configure process determines the correct size of off_t and
3948 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3949 provides for the 'q' format qualifier (if quads are not available,
3950 'q' is silently "demoted" to long). [Jim Jagielski]
3952 *) When the username or password fed to htpasswd is too long, include the
3953 size limit in the error message. Also report illegal characters
3954 (currently only ':') in the username. Add the size restrictions
3955 to the man page. [Ken Coar]
3957 *) Fixed the configure --without-support option so it doesn't result in
3958 an infinite loop. [Marc Slemko]
3960 *) Piped error logs could cause a segfault if an error occured
3961 during configuration after a restart.
3962 [Aidan Cully <aidan@panix.com>] PR#4456
3964 *) If a "Location" field was stored in r->err_headers_out rather
3965 than r->headers_out, redirect processing wouldn't find it and
3966 the server would core dump on ap_escape_html(NULL). Check both
3967 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3968 if Location isn't set. [Doug MacEachern, Ken Coar]
3970 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3971 of the Expat 1.0.2 distribution. [Greg Stein]
3973 *) Replace regexec() calls with calls to a new API stub function
3974 ap_regexec(). This solves problems with DSO modules which use the regex
3975 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3977 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3978 environment variables can be set according to the protocol version
3979 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3981 *) Add DSO support for OpenStep (Mach 4.2) platform.
3982 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997

3996 *) Support for server-parsed and multiview-determined ReadmeName and
3997 HeaderName files in mod_autoindex. Removed the restriction on
3998 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3999 routines will deal with the access issues. (It's now possible to
4000 have {site|group|project|customer|...} wide readmes and headers.)

4040 greater). Use Mac OS X Server layout for now. Clean up dyld code
4041 in unix/os.c, and don't install the dyld error handlers, which
4042 are no longer needed in Mac OS. [Wilfredo Sanchez]

4051 *) Add functionality to the install-bindist.sh script created by
4052 binbuild.sh to use tar when copying distribution files to the

4054 without nesting the new distribution in the old.
4056 install-bindist.sh now detects the local perl5 path to install
4057 apxs and dbmmanage with proper path to perl interpreter.
4059 Add an install-binsupport target which copies the source files
4060 for apxs and dbmmanage to bindist to allow these scripts to
4061 be properly installed relative to the destination serverroot.

4178 htpasswd utility was limiting passwords to only 8 characters.
4181 *) EBCDIC platforms: David submitted patches for two bugs in the
4182 MD5 digest port for EBCDIC machines:
4183 a) the htdigest utility overwrote the old contents of the digest file
4184 b) the Content-MD5 header value (ContentDigest directive) was wrong
4185 when the returned file was not converted from EBCDIC, but was a
4186 binary (e.g., image file) in the first place.
4187 [David McCreedy <mccreedy@us.ibm.com>]
4189 *) support/htpasswd now permits the password to be specified on the

4228 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4229 a roughly 5 fold speed up. [Brian Havard]
4231 *) proxy ftp: instead of using the hardwired string "text/plain" as
4232 a fallback type for files served by the ftp proxy, use the
4233 ap_default_type() function to determine the configured type.
4234 This allows for special configurations like
4235 <Directory proxy:ftp://some.host>
4236 DefaultType gargle/blurb
4238 Additionally, add the Content-Encoding: header to FTP proxy replies
4239 when the encoding is defined (by the AddEncoding directive).
4240 Because it was missing, it was almost impossible to browse compressed
4241 files using the FTP proxy (works now perfectly in Communicator).
4242 The ftp proxy now also returns the Date: and Server: header lines (if not
4243 much else... This code is "somewhat" broken) like normal requests do.
4246 *) Be more smart in APACI's configure script when determining the UID/GID
4247 for User/Group directives and use the determined UID/GID to initialize
4248 the permissions on the proxycachedir.
4249 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4251 *) Changed the forking-prior-to-cleanup in the proxy module to first

4253 the number of fork()s from one/request to just the odd one an hour.
4254 [Dirk-Willem van Gulik]

4284 methods can be access controlled. [Roy Fielding] PR#3821
4286 *) Added PassAllEnv; makes server's entire environment available
4287 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4289 *) ap_uuencode() always added two trailing '='s and encoding of
4290 8 bit characters on a machine with signed char may produced
4291 incorrect results. Additionally ap_uuencode() should now
4292 work correctly on EBCDIC platforms.
4293 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4295 *) WIN32: Binary installer now runs the configuration DLL before
4296 the reboot prompt (which is only given if MSVCRT.DLL system
4297 DLL is new or updated). This should avoid the configuration
4298 directory being empty after installation. [Paul Sutton]

4322 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4323 for 8-bit safeness. [Dean Gaudet]
4325 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4326 because SPARCs have a small machine-specific maximum size for the Global
4327 Offset Table which is often exceeded when compiling one of the larger
4328 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4330 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

4354 *) Remove no longer used non-API function ap_single_module_init().
4355 [Ralf S. Engelschall]
4357 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4360 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4361 to make platform installations easier. [Wilfredo Sanchez]
4363 *) In configure, do not append the target name to the directory path if
4364 the path already contains "apache". [Ralf S. Engelschall]
4366 *) SIGPIPE is now ignored by the server core. The request write routines
4367 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4368 correctly check for output errors and mark the connection as aborted.
4369 Replaced many direct (unchecked) calls to ap_b* routines with the
4370 analogous ap_r* calls. [Roy Fielding]
4372 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4373 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4374 Furthermore map lookups for non-existent keys are now cached as well.
4375 Additionally "txt" maps are now parsed with simple string functions
4376 instead of using ap_pregcomp(). As a side effect a bug that prevented
4377 the usage of keys containing the "," character was fixed.
4378 The changes drastically improve the performance when large rewrite maps
4380 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

4388 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4389 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4391 *) Add %V to mod_log_config, this logs the hostname according to the
4392 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4393 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4395 *) Add support for \n and \t to mod_log_config, can be used to produce
4396 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4398 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4400 *) Added informative error messages for failed munmap() and fseek() calls

4403 *) Added some informative error messages for some failed malloc()
4404 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4406 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4407 is removed. This allows <Directory proxy:*> directives to work and
4408 prevents invalid requests from killing the process.
4409 [Brian Havard <brianh@kheldar.apana.org.au>]
4411 *) Reorganised FAQ document.
4412 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497

4415 David N. Welton: you can now have it generate an HTML TABLE, presumably
4416 for integration into other HTML sources. David updated the ab man page
4417 as well and added some missing descriptions. Thanks!
4418 [David N. Welton <davidw@prosa.it>]

4421 characters in the range 0x80 to 0xff (for example accented characters).
4422 [Paul Sutton] PR#3890
4424 *) Added conditional logging based upon environment variables to
4425 mod_log_config. mod_log_referer and mod_log_agent
4426 are now deprecated. [Ken Coar]
4428 *) Allow apache acting as a proxy server to relay the real
4429 reason of a failure to a client rather than the "internal
4430 server error" it does currently. The general exposure mechanism
4431 can be triggered by any module by setting the "verbose-error-to"
4432 note to "*"; this allows more than just proxy errors to be exposed.
4433 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4435 *) Moved man pages for ab and apachectrl to section 8.
4436 [Wilfredo Sanchez, Roy Fielding]
4438 *) Added -S option to install.sh so that options can be passed to
4439 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4441 *) Tweak modules Makefile generated by Configure so that it handles
4442 the test case of no modules being selected. [chaz@reliant.com]
4444 *) Added a <LimitExcept method ...> sectioning directive that allows
4445 the user to assign authentication control to any HTTP method that
4446 is *not* given in the argument list; i.e., the logical negation
4447 of the <Limit> directive. This is particularly useful for controlling
4448 access on methods unknown to the Apache core, but perhaps known by
4449 some module or CGI script. [Roy Fielding, Tony Finch]
4451 *) Prevent apachectl from complaining if the PIDFILE exists but
4452 does not contain a process id, as might occur if the server is
4453 being rapidly restarted. [Wilfredo Sanchez]
4455 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4457 *) Entity tag comparisons for If-Match and If-None-Match were not being
4458 performed correctly -- weak tags might cause false positives. Also,
4459 strong comparison wasn't properly enforced in all cases.
4460 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4462 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4465 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4466 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4468 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4469 to util.c for parsing an HTTP header field value to extract the next
4470 list item, taking into account the possible presence of nested comments,
4471 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4472 insignificant whitespace and lowercases non-quoted tokens.
4473 [Roy Fielding] PR#2065
4475 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4476 code different from 500. This allows the proxy to, e.g., return
4477 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4479 *) Fix ordering of language variants for the case where the traditional
4480 negotiation algorithm is being used with multiple language variants
4481 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4483 *) Do not round the TCN quality calculation to 5 decimal places,
4484 unlike RFC 2296, because the calculation might need 12 decimal places
4485 to get the right result. [Roy Fielding]
4487 *) Remove unused code to disable transparent negotiation when
4488 negotiating on encoding only, as we now handle encoding too
4489 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4490 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4491 some debugging statements within mod_negotiation. [Koen Holtman]
4493 *) Fixed a rare memory corruption possibility in mod_dir if the index
4494 file is negotiable and no acceptable variant can be found.
4495 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4497 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4498 searching the Win32 registry for script interpreters.
4501 *) Win32: The compiled-in default filename for the error log is now
4502 error.log, which matches the default in the distributed httpd.conf.
4505 *) Win32: Any error messages from -i or -u command line options are now
4506 displayed on the console output rather than sent to the error log.
4507 Also the "Running Apache..." message is not output unless Apache is
4508 going to serve requests. [Paul Sutton]
4510 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4511 and use a private significator ('$apr1$') to mark passwords as
4512 being smashed with our own algorithm. Also abstract the password
4513 checking into a new ap_validate_password() routine. [Ken Coar]
4515 *) Win32: The filename validity checker now allows "COM" but refuses
4516 access to "COM1" through "COM4". This allows filenames such
4517 as "com.name" to be served. [Paul Sutton] PR#3769.
4519 *) BS2000: Adapt to the new ufork() system call interface which will
4520 make subtasking easier on the OSD/POSIX mainframe environment.
4523 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4524 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4526 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4527 use `.db' instead of `.pag' not only for FreeBSD, but also when
4528 the NDBM library looks like Berkeley-DB based.
4529 [Ralf S. Engelschall] PR#3773
4531 *) Add ability to handle DES or MD5 authentication passwords.
4532 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4534 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4536 *) SECURITY: Avoid some buffer overflow problems when escaping
4537 quoted strings. (This overflow was on the heap and we believe
4538 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4540 *) Let src/Configure be aware of CFLAGS options starting with plus
4541 signs as it's the case for the HP/UX compiler.
4542 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4544 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4545 and check to see if the tar we wind up with supports '-h'.
4546 [Jim Jagielski] PR#3671
4548 *) A consistent and conservative style for all shell scripts has been
4549 implemented. Basically, all shell string tests use the traditional
4550 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4551 to protect against bare null variable strings (ie: wrapping both
4552 sides with double quotes and prepending 'x'). 'x' was chosen
4553 because it's more universal and hopefully easier for old shell
4554 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4557 *) The status module now prints out both the main server generation as
4558 well as the generation of each process. Also, the vhost info is
4559 printed with '?notable'. [Jim Jagielski]
4561 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4562 and this makes its functions available to things in src/support.
4565 Changes with Apache 1.3.4
4567 *) Renamed macros status_drops_connection to ap_status_drops_connection
4568 and vestigial scan_script_header to ap_scan_script_header_err,
4569 mostly for aesthetic reasons. [Roy Fielding]
4571 *) The query switch "httpd -S" didn't exit after showing the
4572 vhost settings. That was inconsistent with the other query functions.
4575 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4576 filename to the end of the STANDARD_MODULE_STUFF. Its
4577 presence at the beginning prevented reporting of the filename
4578 for modules compiled before 1 January 1999. [Ken Coar]
4580 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4581 to detect and prevent access to special DOS device file names.
4582 [Paul Sutton, Ken Parzygnat]
4584 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4585 and Makefile_win32_debug.txt (debug build) that work on Win95.
4586 Run each of the following from the src directory:
4587 nmake /f Makefile_win32.txt # compiles normal build
4588 nmake /f Makefile_win32.txt install # compiles and installs
4589 nmake /f Makefile_win32.txt clean # removes compiled junk
4590 nmake /f Makefile_win32_debug.txt # compiles debug build
4591 nmake /f Makefile_win32_debug.txt install
4592 nmake /f Makefile_win32_debug.txt clean
4595 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4596 to build binary distributions. [Lars Eilebrecht]
4598 *) IndexOptions SuppressColumnSorting only turned off making
4599 the column headers anchors; you could still change the display
4600 order by manually adding a '?N=A' or similar query string to the
4601 URL. Now SuppressColumnSorting locks in the sort order so
4602 it can't be overridden this way. [Ken Coar]
4604 *) Added IndexOrderDefault directive to supply a default sort order
4605 for FancyIndexed directory listings. [Ken Coar] PR#1699
4607 *) Change the ap_assert macro to a variant that works on all platforms.
4608 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4610 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4611 search for an underscore on dlsym() (as it's already the case
4612 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4614 *) Small fix for mod_env.html: The module was documented as to be _not_
4615 compiled into Apache per default, although it _IS_ compiled into
4616 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4618 *) Instead of fixing a bug in the generation procedure for config.status (a
4619 backslash was missing) we remove the bug together with it's complete
4620 context because the special cases of the past can now no longer occur
4621 because of the recent magic for the --with-layout default.
4622 [Ralf S. Engelschall] PR#3590
4624 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4625 making sure the src/support/ tools are _forced_ to be build last (they
4626 depend on other libraries).
4627 [Markus Theissinger <markus.theissinger@gmx.de>]
4629 *) Fix installation procedure: Now that os-inline.c is actually used (a
4630 recently fixed bug prevented this) we need to also install os-include.c
4631 in addition to os.h into the PREFIX/include/ location or building of
4632 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4634 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4635 allow us to distinguish between a garbled DSO (or even a file which isn't
4636 an Apache module DSO at all) and a DSO which doesn't match the current
4637 Apache API. [Ralf S. Engelschall] PR#3152
4639 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4640 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4641 match case insensitive (this especially avoids nasty patterns like
4642 `[tT][eE][sS][tT]'). Second two additional internal map functions
4643 `escape' and `unescape' were added which can be used to escape/unescape
4644 to/from hex-encodings in URLs parts (this is especially useful in
4645 combination with map lookups).
4646 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4648 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4649 forgotten (because it was a macro) in the symbol renaming process.
4650 [Ralf S. Engelschall]
4652 *) Fix some inconsistencies related to the scopes of directives. The only
4653 user visible change is that the directives `UseCanonicalName' and
4654 `ContentDigest' now use the (more correct) `Options' scope instead of
4655 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4657 *) Using DSO, the Server token was being mangled. Specifically, the
4658 module's token was being added first before the Apache token. This
4659 has been fixed. [Jim Jagielski]
4661 *) Major overhaul of mod_negotiation.c, part 2.
4662 - properly handle "identity" within Accept-Encoding.
4663 - allow encoded variants in RVSA negotiation and let them appear in
4664 the Alternates field using the non-standard "encoding" tag-list.
4665 - fixed both negotiation algorithms so that an explicitly accepted
4666 encoding is preferred over no encoding if "identity" is not
4667 included within Accept-Encoding.
4668 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4669 of large substring sequences.
4670 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4673 *) Major overhaul of mod_negotiation.c, part 1.
4674 - cleanups to mod_negotiation comments and code structure
4675 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4676 support for everything in the upcoming HTTP/1.1
4677 revision (draft-ietf-http-v11-spec-rev-06.txt).
4678 - language tag matching also handles tags with more than 2
4680 - empty Accept, Accept-Language, Accept-Charset headers are
4681 processed correctly; previously an empty header would make all
4682 values acceptable instead of unacceptable.
4683 - allowed for q values in Accept-Encoding
4684 - added support for transparent content negotiation (rfc2295 and
4685 rfc2296) (though we do not implement all features in these drafts,
4686 e.g. no feature negotiation). Removed old experimental version.
4687 - implemented 'structured entity tags' for better cache correctness
4688 (structured entity tags ensure that caches which can deal with Vary
4689 will (eventually) be updated if the set of variants on the server
4691 - this involved adding a vlist_validator element to request_rec
4692 - this involved adding the ap_make_etag() function to the global API
4693 - modified guessing of charsets used by Apache negotiation algorithm
4694 to guess 'no charset' if the variant is not a text/* type
4695 - added code to sort multiviews variants into a canonical order so that
4696 negotiation results are consistent across backup/restores and mirrors
4697 - removed possibility of a type map file resolving to another type map
4698 file as its best variant
4699 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4701 *) RFC2396 allows the syntax http://host:/path (with no port number)
4702 but the proxy disallowed it (ap_proxy_canon_netloc()).
4703 [David Kristol <dmk@bell-labs.com>] PR#3530
4705 *) When modules update/modify the file name in the configfile_t structure,
4706 syntax errors will report the updated name, not the original one.
4707 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
4709 *) Correct some filename case assumptions from WIN32 to
4710 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4712 *) For %v log ServerName regardless of the UseCanonicalName
4713 setting (similarly for %p). [Dean Gaudet]
4715 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4716 rather late (too late for some invocations of TestCompile).
4717 This improves the make environment available to TestCompile and
4718 the *.module scripts. [Martin Kraemer]
4720 *) The hashbang emulation code in ap_execve.c would interpret
4721 #!/hashbang/scripts correctly, but failed to fall back to a
4722 standard shell for scripts which did NOT start with #!
4723 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4725 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4728 *) Update APXS manual page: some -q option arguments were missing
4729 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4731 *) Cleanup the command line options: `-?' was documented to show
4732 the usage list but does it with an error because `?' is not a valid
4733 command. OTOH a lot of users expect `-h' to print such a usage list and
4734 instead are annoyed for ages by our huge unreadable list of directives.
4735 So we now changed the command line options this way:
4737 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4738 very similar to the popular linker option.
4740 Intent: while -l gives the small list of modules, -L now gives the
4741 large list of directives implemented by these modules. This is also
4742 consistent with -v (short version info) and -V (large version info).
4744 Intent: it's now the expected option ;-)
4745 The manual page was adjusted accordingly.
4746 [Ralf S. Engelschall] PR#2714
4748 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4749 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4751 *) Removed recently introduced bugs and disfigurements in APACI:
4752 o fixed argument line processing: using $args was broken: It was not
4753 initialized and using args="$args $apc_option" and even args="$args
4754 \"$apc_option\"" fails in the second processing round for any arguments
4755 containing whitespaces. The only correct way is to use the construct
4756 "$@" (but not possible here) or iterate _both_ times over the implicit
4757 argument line (no argument to for-loop) which is what we now use.
4758 o make --with-layout=Apache the default without creating
4759 redundancy (copying the --with-layout block in the argument parsing
4760 loop). We achieve this by using the "$@" construct together with the
4761 `set' command to prepend --with-layout=Apache to the command line in
4762 case --with-layout is not used.
4763 o fixed auto-suffix handling now that config.layout exists.
4764 Paths which are auto-suffixed are marked with a trailing plus sign in
4765 config.layout and every path now can be marked this way (not only the
4766 four paths for which we do it currently). Additionally the suffix is
4767 no longer a static one. Instead it's now `/<target>' where <target> is
4768 the argument of the --target option or per default `httpd'.
4769 o allow also tabs (and only spaces) where we match whitespaces
4770 o various fixes and cleanups related to used shell coding style
4771 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4772 o trimmed output of --help to fit into 80 columns
4773 [Ralf S. Engelschall]
4775 *) Added two new core API functions, ap_single_module_configure() and
4776 ap_single_module_init(), which are now used by mod_so to configure a module
4777 after loading. [Ralf S. Engelschall]
4779 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4780 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4781 of ap_config.h to allow serialized accept for multiport listens.
4782 [Roy Fielding, Curt Sampson] PR#3120
4784 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4785 of ap_config.h that would skip several defines if DEFAULT_GROUP
4786 was overridden. [Roy Fielding]
4788 *) PORT: The I86 version of DGUX has support for strncasecmp and
4789 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4791 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4792 defined before it might be used. [Victor Khimenko]
4794 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4795 [Tom Serkowski <tks@bsdi.com>] PR#3453
4797 *) Make generation of src/Configuration.apaci more robust: It failed to
4798 differenciate between modules when one module name was a postfix of
4799 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4800 just XXX (think about totally non-standard names like "apache_ssl", too).
4801 [Ralf S. Engelschall] PR#3380
4803 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4804 since 1.3b7) and make whitespace handling more robust (it failed horrible
4805 when whitespaces were present in the arguments of -D options).
4806 [Ralf S. Engelschall] PR#3240
4808 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4809 creates an external package shadow tree in DIR before the local build
4810 shadow tree is generated under DIR. This way one can have the extracted
4811 Apache distribution tree read-only on NFS or CDROM and still build Apache
4812 from these sources. An automatically triggered VPATH-like mechanism is
4813 provided through the TOP variable, too.
4814 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
4816 *) Fix negotiation so that a Vary response header is correctly
4817 generated when, for a particular dimension, variants only vary
4818 in having or not having a value for that dimension. [Paul Sutton]
4820 *) Fix negotiation so that we prefer an encoded variant over an
4821 unencoded variant if the user-agent explicitly says it can
4822 accept that encoding. Previously we always preferred the unencoded
4824 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4826 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4827 and the usage page was inconsistent with the functionality and manpage.
4828 [Ralf S. Engelschall]
4830 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4831 They can occur multiple times and their arguments (`xxx') are passed AS
4832 IS to the compiler/linker command. [Ralf S. Engelschall]
4834 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4835 procedure of mod_rewrite: very long keys were truncated.
4836 [Ralf S. Engelschall]
4838 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4839 identifier, currently "Apache" and "GNU" are pre-defined in the file
4840 config.layout. Custom layouts are possible by using FILE:ID as the
4841 argument where the layout ID is taken from FILE.
4843 The config.layout file consists of <Layout ID>..</Layout> sections
4844 where inside those sections "path_variable: path_value" pairs can be
4845 specified. These lines are converted to path_variable='path_value'.
4847 *) Add a DefaultLanguage directive so that files missing a language
4848 extension (e.g., .fr, .de) can be labelled as being some other
4849 default language. DefaultLanguage can appear in <Directory> and
4850 <Files> containers as well as .htaccess files. [Paul Sutton]
4853 *) Fix TARGET configuration when configuring and installing using
4854 APACI configure. TARGET now defines the basename of the configuration
4855 file, startup script, manual page, etc. log_error_core() now reports
4856 the server binary name given by argv[0]. TARGET can now also be defined
4857 with --target=TARGET parameter passed to APACI configure.
4858 [Ralf Engelschall, Randy Terbush]
4860 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4861 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

4884 a gcc 2.8.1 compiled apache is logging client addresses with all
4885 bits set (255.255.255.255). This is the second such problem caused

4965 in the Configuration[.apaci] file. Two special and important variants are
4966 supported for the option argument: first BEGIN:foo which permutes module
4967 mod_foo with the begin of the module list, i.e. it `moves' the module to
4968 the begin of the list (gives it lowest priority). And second foo:END
4969 which permutes mod_foo with the end of the module list, i.e. it `moves'
4970 the module to the end of the list (gives it highest priority).

4986 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
4987 ResourceConfig directives on Win32. Also add a note to the effect

4989 a User directive is encountered on Win32.

4992 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
4993 broken since Apache 1.3.1 where we took out compressing of multiple
4994 spaces in ap_cfg_getline().

4997 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not

5002 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
5004 *) Merge the contents of the {srm,access}.conf-dist* files into the
5005 httpd.conf-dist* files. The srm and access files now contain
5006 only comments, and httpd.conf has all the combined contents in
5007 a rational order. [Ken Coar]
5009 *) PORT: DSO/ELF support for FreeBSD 3.0.
5010 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
5012 *) Add a "default-handler" handler that calls the default_hander()
5013 function which is normally called for static content. This allows
5014 you to override a specific handler. [Marc Slemko]
5016 *) Further simplify checking for absolute paths by replacing an
5017 hard-coded syntax check with a call to a routine we already created to
5018 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
5020 *) Log an error if we encounter a malformed "require" directive
5021 in mod_auth if we know that we know that no other module can
5022 deal with it. [Marc Slemko]
5024 *) Remove ap_private_extern method of hiding conflicting symbols
5025 on the NEXT platform because it is not correct for all versions,
5026 and the versions for which it is correct are unknown.
5027 [Wilfredo Sanchez <wsanchez@apple.com>]
5029 *) Fix inheritance of IndexOptions NameWidth and remove unintended

5033 is encountered in an .htaccess file somewhere down the tree.
5036 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
5038 *) Fixed a segmentation violation in mod_proxy when a response is
5039 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
5041 Changes with Apache 1.3.3
5043 *) Added a complete implementation of the Expect header field as
5044 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
5045 response when we already know the final status, which is mighty
5046 useful for PUT responses that result in 302 or 401. [Roy Fielding]
5048 *) Remove extra trailing whitespace from the getline results as part
5049 of the protocol processing, which is extra nice because it works
5050 between continuation lines, is almost no cost in the normal case
5051 of no extra whitespace, and saves memory. [Roy Fielding]
5053 *) Added new HTTP status codes and default response bodies from the
5054 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
5055 HTTP Extension Framework (510) specifications. Did not add the
5056 WebDAV 424 and 425 codes because they are bogus. We don't use any
5057 of these codes yet, but they are now available to 3rd-party modules.
5060 *) Fix a possible race condition between timed-out requests and the
5061 ap_bhalfduplex select that might result in an infinite loop on
5062 platforms that do not validate the descriptor. [Roy Fielding]
5064 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
5065 running Apache server [Paul Sutton]

5068 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
5071 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
5073 *) Add the server signature text (from the core ServerSignature directive)
5074 to the list of envariables available to scripts, SSI, and the like.
5077 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
5078 [M. Laak <maert@proinv.ee>] PR#3108
5080 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
5081 calculation in mod_status for all systems which don't have POSIX
5082 sysconf() (like UTS 2.1) and not only for the NEXT platform.
5083 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
5085 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
5086 mod_auth_db by using ap_getword_white() (which uses ap_isspace())

5088 but not tabs). [James Morris <jmorris@intercode.com.au>,

5129 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
5130 <steve.cameron@compaq.com>]
5132 *) Reconstructed the loop through multiple htaccess file names so
5133 that missing files are not confused with unreadable files.
5136 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
5137 errno on an error, which leads to one error being mistaken for
5138 another when reading non-existent .htaccess files.
5141 *) OS/2: The new header tests get things right, need to update
5142 ap_config.h. [Brian Havard]
5144 *) The Perl %ENV hash will now be setup by default when using the
5145 mod_include `perl' command [Doug MacEachern]

5156 *) Avoid possible line overflow in Configure: Use an awkfile to
5157 handle the creation of modules.c [Jim Jagielski]
5159 Changes with Apache 1.3.2
5161 *) Fix bug in ap_remove_module(), which caused problems for dso's
5162 who were the top_module. [Doug MacEachern]
5164 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
5165 mod_auth_db to both be friendly to users who wants to use this version
5166 and to avoid problems under platforms where only version 2.x is present.
5167 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
5169 *) When using ap_log_rerror(), make the error message available to the
5170 *ERROR_NOTES envariables by default. [Ken Coar]
5172 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
5173 You now must define a BS2000Account name for the server User.
5174 This has fewer security implications than the old approach.
5177 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
5178 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
5179 platform to make the braindead HPUX linker happy. Notice, for the module
5180 DSOs we don't have to use this, because these are loaded manually (and
5181 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
5183 *) Remove 64 thread limit on Win32.
5184 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5186 *) Remove redundant substitutions in top-level Makefile.tmpl.
5187 [Ralf S. Engelschall]
5189 *) Fix APACI's `Group' configuration adjustment - especially for Linux
5190 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
5192 *) Make PrintPath work generically instead of having one version
5193 strictly for OS/2. [Jim Jagielski, Brian Havard]
5195 *) Fix the recently introduced C header file checking: We now use the C
5196 pre-processor pass only (and no longer the complete compiler pass) to
5197 determine whether a C header file exists or not. Because only this way
5198 we're safe against inter-header dependencies (which caused horrible
5199 portability problems). The only drawback is that we now have a CPP
5200 configuration variable which has to be determined first (we do a similar
5201 approach as GNU Autoconf does here). When all fails the user still has
5202 the possibility to override it manually via APACI or src/Configuration.
5203 As a fallback for the header check itself we can directly check the
5204 existance of the file under /usr/include, too.
5205 [Ralf S. Engelschall] PR#2777
5207 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
5208 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
5209 ap_private_extern defined to hide symbols that conflict with loaded
5210 dynamic libraries on the NEXT and RHAPSODY platforms.

5225 *) Fix possible buffer overflow situation in suexec.c.
5226 [Jeff Stewart <jws@purdue.edu>] PR#2790
5228 *) Add some more LIBS for the SCO5 platform which are needed for the already
5229 used -lprot. It's actually a bug in SCO5, of course.
5230 [Ronald Record <rr@sco.com>] PR#2533
5232 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
5233 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
5235 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
5236 platform, because it's only supported under version 4.0 and higher. But
5237 because our GuessOS is still unaware of Digital UNIX versions and the
5238 -msym is just to optimize the DSO statup time a little bit it's safe and
5239 best when we leave it out now. [Ralf S. Engelschall] PR#2969
5241 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
5242 functions: First all three functions no longer fail on strings containing
5243 "%" chars and second ap_log_printf() no longer does a double-formatting
5244 (instead it directly passes through the message to be formatted to the
5245 real internal formatting function). [Ralf S. Engelschall] PR#2941
5247 *) Allow "Include" directives anywhere in the server config
5248 files (but not .htaccess files). [Ken Coar] PR#2727
5250 *) The proxy was refusing to serve CONNECT requests except to
5251 port 443 (https://) and 563 (snews://). The new AllowCONNECT
5252 directive allows the configuration of the ports to which a
5253 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5255 *) mod_expires will now act on content that is not sent from a file
5256 on disk. Previously it would never add an Expires: header to
5257 any response that did not come from a file on disk; the only
5258 case where it still doesn't (and can't) add one for that type of
5259 content is if you are using a modification date based setting.
5260 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
5262 *) Problems encountered during .htaccess parsing or CGI execution
5263 that lead to a "500 Server Error" condition now provide explanatory
5264 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
5267 *) Add NameWidth keyword to IndexOptions directive so that the
5268 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
5271 *) Recognize lowercase _and_ uppercase `uname' results under
5272 SCO OpenServer. [David Coelho <drc@ppt.com>]
5274 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5275 a common problem of (mis-administrated?) IIS servers, make the apache
5276 proxy immune to these errors (and ignore the duplicates, but log
5277 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5279 *) The <IfModule and <IfDefine block starting directives now only
5280 allow exactly one argument. Previously, the optional negation
5281 character '!' could be separated by whitespace without a syntax
5282 error being reported, albeit defeating the IfModule functionality
5283 (enclosed directives would ALWAYS be executed). By using the
5284 stricter syntax, these hard-to-track errors can be avoided.
5287 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5288 cause the standalone FancyIndexing directive to logically OR
5289 into any existing IndexOptions settings rather than wiping
5290 them out. [Ken Coar]
5292 *) Changes in ftp proxy: make URL parsing simpler by using the
5294 + Add display of the "current directory" in cases where it's
5295 different from the supplied path (e.g., ftp://user@host/ lives
5296 in /home/user, not in /, therefore clicking on "../" in the
5297 starting directory might send us to /home/).
5298 + When ftp login fails, (esp. when a user name was part of the
5299 URL already), we now return [401 Unauthorized ] to allow the
5300 browser to pop up an authorization dialog. This makes passwords
5301 slightly less visible (they don't appear in the regular log files)
5302 and implements a functionality that other www proxy servers
5306 *) Triggered by the recent "Via:" header changes, the proxy module would
5307 dump core for replies with invalid headers (e.g., duplicate
5308 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5309 core dump is avoided. Also, broken replies are not cached.
5310 [Martin Kraemer] PR#2914
5312 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
5313 plop gmon.out profile data for each child [Doug MacEachern]
5315 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
5316 config.status script to be immune against arguments with whitespaces.
5317 [Yves Arrouye <yves@apple.com>] PR#2866
5319 *) Replace the inlined information grabbing stuff for the configuration
5320 adjustment feature (no --without-confadjust) with calls to a new helper
5321 script `buildinfo.sh' which is both more flexible and already proofed to
5322 be more robust against platform differences. This mainly fixes the
5323 recently occured ``sed: command garbled: ...'' problems.
5324 [Ralf S. Engelschall] PR#2776, PR#2848
5326 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
5327 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
5328 without complains after we recently added the POST feature.
5329 [Ralf S. Engelschall]
5331 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
5332 modules as API functions and we forgot them at the big symbol renaming.
5333 [Ralf S. Engelschall]
5335 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
5336 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895
5338 *) Dynamically size the filename column of mod_autoindex output.
5341 *) Add the ability to do POST requests to the ab benchmarking tool.
5342 [Kurt Sussman <kls@best.com>] PR#2871
5344 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5345 5 to 10 because there are some users out there who always have 5 to 8
5346 variables in one RewriteRule and had to patch mod_rewrite.h for every
5347 release. So 15 should be now more than enough, even for them. (I never
5348 needed more than 4 in my RewriteRules ;-)
5349 [Ralf S. Engelschall]
5351 *) Make the proxy generate and understand Via: headers
5354 *) Change the proxy to use tables instead of array_headers for
5355 the header lines. [Martin Kraemer]
5357 *) Make sure the config.status file is not overridden when just
5358 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
5360 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
5361 provide a way to trace API changes that add functionality but do
5362 not create a compatibility issue for precompiled modules, etc.
5363 See include/ap_mmn.h for more details. [Randy Terbush]
5365 *) Fix suexec installation under `make install root=xxx' situation.
5366 [Ralf S. Engelschall]
5368 *) Extend the output of the -V switch to include the paths of all
5369 compiled-in configuration files, if they were overridden at
5370 compile time, for least astonishment of the user.
5373 *) When READing a request in ExtendedStatus mode, the "old"
5374 vhost, request and client information is not displayed.
5377 *) STATUS is no longer available. Full status information now
5378 run-time configurable using the ExtendedStatus directive.
5381 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5382 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5383 a function which can be used to perform bulk update operations
5384 on tables in a more efficient manner. [Dean Gaudet]
5386 *) SECURITY: Added compile-time and configurable limits for
5387 various aspects of reading a client request to avoid some simple
5388 denial of service attacks, including limits on maximum request-line
5389 size (LimitRequestLine), number of header fields (LimitRequestFields),
5390 and size of any one header field (LimitRequestFieldsize). Also added
5391 a configurable directive LimitRequestBody for limiting the size of the
5392 request message body. [Roy Fielding]
5394 *) Make status module aware of DNS and logging states, even if
5395 STATUS not defined. [Jim Jagielski]
5397 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
5399 *) Enhance mod_speling so that CheckSpelling can be used in
5400 <Directory> containers and .htaccess files. [Ken Coar]
5402 *) API: new ap_custom_response() function for hooking into the
5403 ErrorDocument mechanism at runtime [Doug MacEachern]
5405 *) API: new ap_uuencode() function [Doug MacEachern]
5407 *) API: scan_script_header_err_core() now "public" and renamed
5408 ap_scan_script_header_err_core() [Doug MacEachern]
5410 *) The 'status' module will now show the process pid's and their
5411 state even without full STATUS accounting. [Jim Jagielski]
5413 *) Restore the client IP address to the error log messages, this
5414 was lost during the transition from 1.2 to 1.3. Add a new
5415 function ap_log_rerror() which takes a request_rec * and
5416 formats it appropriately. [Dean Gaudet] PR#2661
5418 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5419 whitespace in input lines -- including within quoted strings.
5421 but leading and trailing whitespace should continue to be
5422 stripped [Martin Kraemer]
5424 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5425 the ugly use of an env. variable and use command-line args for
5426 alternate $PATH. Make more like advanced 'type's as well.
5429 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
5430 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
5431 <alain.st-denis@ec.gc.ca>] PR#2736
5433 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
5435 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
5436 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
5437 directory was renamed to src/os/os2/ for consistency.
5438 [Brian Havard, Ralf S. Engelschall]
5440 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5441 files (here modules) against other DSO files (here shared libraries).
5442 This is done by determining a subset of LIBS which can be safely used for
5443 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5444 disabled for all platforms to avoid problems with this (experimental)
5445 rule. But we provide it now for those people how ran into problems and
5446 want to came out by forcing linking against DSOs.
5447 [Ralf S. Engelschall] PR#2587
5449 *) Fix suEXEC start message: Has to be of `notice' level to really get

5465 *) One more portability fix for APACI shadow tree support: Swap order of awk
5466 and sed in top-level configure script to avoid sed fails on some
5467 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

5734 as <IfModule>..</IfModule> sections) which can be used to skip or process
5735 contained commands dependend of ``-D PARAMETER'' options on the command
5736 line. This can be used to achieve logical conditions like <IfDefine
5737 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)

5750 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5751 in top-level configure script to avoid sed fails on some platforms (for
5752 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5753 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5755 *) Improve performance of directory listings (mod_autoindex) by comparing
5756 integer keys (last-modified and size) as integers rather than converting
5757 them to strings first. Also use a set of explicit byte tests rather
5758 than strcmp() to check for parent directory-ness of an entry. Oh, and
5759 make sure the parent directory (if displayed) is *always* listed first
5760 regardless of the sort key. Overall performance winnage should be good
5761 in CPU time, instruction cache, and memory usage, particularly for large
5762 directories. [Ken Coar]
5764 *) Add a tiny but useful goody to APACI's configure script: The generation
5765 of a config.status script (as GNU Autoconf does) which remembers the used
5766 configure command and hence can be used to restore the configuration by
5767 just re-running this script or for remembering the configuration between
5769 [Ralf S. Engelschall]
5771 *) Add httpd -t (test) option for running configuration syntax tests only.
5772 If something is broken it complains and exits with a return code
5773 non-equal to 0. This can be used manually by the user to check the Apache
5774 configuration after editing and is also automatically used by apachectl
5775 on (graceful) restart command to make sure Apache doesn't die on restarts
5776 because of a configuration which is now broken since the last (re)start.
5777 This way `apachectl restart' can be used inside cronjobs without having
5778 to expect Apache to be falling down. Additionally the httpd -t can be run
5779 via `apachectl configtest'.

5933 proxy errors to be treated by ErrorDocument's as well. For this
5934 purpose, a new module-to-core communication variable "error-notes"
5935 was introduced; the proxy (and possibly other modules) communicates
5936 its error text using this variable. Its content is copied to a new
5937 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.

5979 414 responses. [Ed Korthof]
5981 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
5983 *) Fix discrepancy in proxy_ftp.c which was causing failures when
5984 trying to connect to certain ftpd's, such as anonftpd.
5985 [Rick Ohnemus <rick@ecompcon.com>]
5987 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
5988 logfile instead of fiddling around itself with child spawning stuff.
5989 [Ralf S. Engelschall]
5991 *) Made RefererIgnore case-insensitive.
5993 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
5996 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
5997 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
6000 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
6002 *) Fix support script `dbmmanage': It was unable to handle some sort
6003 of passwords, especially passwords with "0" chars.

6006 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
6007 [Ben Laurie] PR#2238
6009 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
6010 library), so CGI handling has been changed to use Win32 native handles
6011 instead of C file descriptors.
6012 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
6014 *) The proxy cache would store an incorrect content-length in the cached
6015 file copy after a cache update. That resulted in repeated fetching
6016 of the original copy instead of using the cached copy.
6017 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
6019 *) The Makefiles assumed that DSO files are build via $(LD). This
6020 is broken for two reasons: First we never defined at least LD=ld
6021 somewhere to make sure this works (it was silently assumed that most Make
6022 provide a built-in LD definition - ARGL!) and second using the generic LD
6023 variable is not the truth. Instead a special variable named LD_SHLIB is
6024 reasonable because although "ld" is usually the default, the command for
6025 building DSO files can be "libtool" or even "cc" on some systems.
6026 [Ralf S. Engelschall]
6028 *) Replace the AddVersionPlatform directive with ServerTokens which
6029 provides for more control over the format of the Server:
6030 header line. SERVER_SUBVERSION is no longer supported;
6031 all module should use the ap_add_version_component()
6032 API function instead. [Jim Jagielski]
6034 *) Support for the NCR MP/RAS 3.0
6035 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
6037 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
6038 not retrieved in src/Configure and thus was not useable.
6039 [Ralf S. Engelschall]
6041 *) Various Makefile consistency cleanups:
6042 - make OSDIR also automatically be relative to src/ like INCDIR
6043 - SUBDIRS is now generated in src/Makefile only and not in
6044 Makefile.config because it is a local define for this location.
6045 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
6046 any Makefile but make sure that at least the "-K inline" is kept in
6048 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
6049 - updated the dependencies theirself
6050 - removed not existing SHLIB variable from "clean" targets
6051 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
6052 already exists and OBJS_PIC are also just plain objects and have not
6053 directly to do with "shared" things. The only difference is that they
6054 contain PIC. So OBJS_PIC is the more canonical name.
6055 - Updated the Makefile-dependency lines for OBJS_PIC
6056 - Removed the Makefile-dependency line in Configure to avoid double
6058 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
6059 of xxx.lo as GNU libtool does with its PIC objects
6060 - reduce local complexity in modules Makefile.tmpl by moving the last
6061 existing target "depend" to the generation section in Configure, too.
6062 - removed the historical $(SPACER) which was used in the past together
6063 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
6064 is no longer needed.
6065 - force the build and run of the gen_xxx programs under main/ as the
6066 first step before building the objects because it looks cleaner
6067 [Ralf S. Engelschall]
6069 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
6072 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
6075 *) WIN32: Don't force ISAPI headers to finish with \n.
6076 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
6078 *) When opening "configuration" files (like httpd.conf, htaccess
6079 and htpasswd), Apache will not allow them to be non-/dev/null
6080 device files. This closes a DoS hole. At the same time,
6081 we use ap_pfopen to open these files to handle timeouts.
6082 [Jim Jagielski, Martin Kraemer]
6084 *) Apache will now log the reason its httpd children exit if they exit
6085 due to an unexpected signal. (It requires a new porting define,
6086 SYS_SIGLIST, which if defined should point to a list of text
6087 descriptions of the signals available. See PORTING.) [Dean Gaudet]
6089 *) WIN32: chdir() doesn't make sense in a multithreaded environment
6090 like WIN32. Before, Win32 CGI's could have had sporadic failures
6091 if a chdir call from one thread was made between another chdir call
6092 and a spawn in another thread. So, for now don't chdir for CGI scripts
6093 in WIN32. The current CGI "spec" is unclear as to whether it's
6094 necessary. Long-term fix is to either serialize the chdir/spawn combo
6095 or use WIN32 native calls to spawn a process. This temp fix was
6096 necessary to remove this as a showstopper for 1.3's release.
6099 *) Cleanup the suEXEC support in APACI and make it more safe:
6100 1. Add big fat hint in INSTALL about risks and to read the
6101 htdocs/manual/suexec.html document before using the suexec-related
6103 2. Make sure the user has at least provided one --suexec-xxxx option
6104 (specifies suEXEC parameters) in addition to --enable-suexec option.
6105 If only --enable-suexec is given APACI stops with a hint to INSTALL
6106 and htdocs/manual/suexec.html documents.
6107 3. Provide two additional --suexec-xxxx options to make the suEXEC
6108 configuration complete (especially for package maintainers who else
6109 had to patch the source tree) by providing ways to configure minimal
6110 UID/GID and safe PATH, too.
6111 [Ralf S. Engelschall]
6113 *) Cleanup of the `configure --shadow' process:
6114 - make sure the configure script creates its temporary files in the
6115 shadow tree to avoid conflicts with parallel configure runs
6116 - removed unnecessary option "-r" from "rm" call for Makefiles
6117 - make sure the configure scripts creates the shadow-wrapper Makefile
6118 only when no shadow trees already exists
6119 - make sure "make distclean" removes the shadow-wrapper Makefile but only
6120 when no more shadow trees exists
6121 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
6122 as fast (in the past it needed 70sec, now it runs just 38sec)
6123 - make sure CVS does not complain about the created files
6124 Makefille.<gnutriple> and directories src.<gnutriple>
6125 [Ralf S. Engelschall]
6127 *) Added the ap_add_version_component() API routine and the
6128 AddVersionPlatform core directive. The first allows modules to
6129 declare themselves in the Server response header field value,
6130 augmenting the SERVER_SUBVERSION define in the Configuration file
6131 with run-time settings (more useful in a loadable-module environment).
6132 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
6133 into the server version string. [Ken Coar] PR#2056
6135 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
6138 *) Emit the "Accept-Range" header for the default handler.
6139 [Brian Behlendorf] PR#1464
6141 *) Add a note to httpd.conf-dist that apache will on some systems fail
6142 to start when the Group # is set to a negative or large positive value.
6145 *) Make sure the module execution order is correct even when some modules
6146 are loaded under runtime (`LoadModule') via the DSO mechanism:
6147 1. The list of loaded modules is now a dynamically allocated one
6148 and not the original statically list from modules.c
6149 2. The loaded modules are now correctly setup by LoadModule for
6150 later use by the AddModule command.
6151 3. When the DSO mechanism for modules is used APACI's `install'
6152 target now enables all created `LoadModule' lines per default because
6153 this is both already expected by the user _and_ needed to avoid
6154 confusion with the next point and reduces the Makefile.tmpl complexity
6155 4. When the DSO mechanism for modules is used, APACI's `install'
6156 target now additionally makes sure the module list is reconstructed
6157 via a complete `ClearModuleList+AddModule...' entry.
6158 5. The support tool `apxs' now also makes sure an AddModule command
6159 is added in addition to the LoadModule command.
6160 6. The modules.c generation was extended to now contain two
6161 comments to make sure no one is confused by the confusing terminology
6162 of loading/linking (we use load=link+load & link=activate instead of
6163 the obvious load=activate & link=link :-( )
6164 This way now there is no longer a difference under execution time between
6165 statically and dynamically linked modules.
6166 [Ralf S. Engelschall]
6168 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
6169 Big Symbol Renaming. [Ralf S. Engelschall]
6171 *) Add a comment to mod_example.c showing the format of a FLAG command
6174 *) Standardized the time format in mod_status to match that of other
6175 places in the code (e.g. DATE_GMT). PR#1551
6177 *) Fix handling of %Z in timefmt strings for those platforms with no time
6178 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
6181 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
6182 feature compatible with 'UseCanonicalName off' by changing
6183 r->server->server_hostname to ap_get_server_name(). And I changed some
6184 functions which use r->server->port to use ap_get_server_port() instead,
6185 because if there's no Port directive in the config r->server->port is 0.
6188 *) get/set_module_config are trivial enough to be better off inline. Worth
6189 1.5% performance boost. [Dean Gaudet]
6191 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
6192 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
6195 *) [BS2000 security] BS2000 needs an extra authentication to initialize
6196 the task environment to the unprivileged User id. Otherwise CGI scripts
6197 would have a way to gain super user access. [Martin Kraemer]
6199 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
6200 absolute path, only log base name of logging source as is done
6201 in unix. [Martin Kraemer]
6203 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6204 the encoding type from the Accept-Encoding header (if it's there)
6205 and use it in the response, as that's probably what it'll be expecting.
6206 [Ronald.Tschalaer@psi.ch]
6208 *) Fix to mod_alias: translate_alias_redir is dealing with
6209 a URI, not a filename, so the check for drive letters for win32
6210 and emx is not necessary. [Dean Gaudet]
6212 *) WIN32: Allow .cmd as an executable extension.

6218 *) Child processes can now "signal" (by exiting with a status
6219 of APEXIT_CHILDFATAL) the parent process to abort and
6220 shutdown the server if the error in the child process was
6221 fatal enough. [Jim Jagielski]
6223 *) mod_autoindex's find_itme() was sensitive to MIME type case.
6224 [Jim Jagielski] PR#2112
6226 *) Make sure the referer_log and agent_log entries in the default httpd.conf
6227 file are also adjusted for the actual relative installation paths.

6230 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
6232 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
6235 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6236 Additionally the checks for finding the vendor DSO library were moved
6237 from mod_so.c to Configure because first it needs $PLAT etc. and second
6238 mod_so already uses an abstraction layer and does not fiddle with the
6239 vendor functions itself.

6242 *) PORT: Some optimization defines for NetBSD
6243 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6245 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6246 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6248 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6249 AIX variants should work fine, too. Even AIX 3.x should work). This is
6250 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6251 which we put into a os/unix/os-dso-aix.c file.
6252 [Ralf S. Engelschall]
6254 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6255 that we should use NET_SIZE_T == int but the include files force size_t.
6256 [Ralf S. Engelschall]
6258 *) Fix two bugs in select() handling in http_main.c.
6261 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6262 is unset (as it is in situations like timeouts) where it is unclear
6263 whether errno is set or not. [Martin Kraemer]
6265 *) Just having APACI's localstatedir is too general and not enough for most
6266 of the systems. 1.3b6 again required manual APACI patches by package
6267 maintainers from RedHat and FreeBSD because for their filesystem layout a
6268 little bit more flexibility in configuring the paths is needed. Hence we
6269 provide three additional configure options (--runtimedir, --logfiledir,
6270 --proxycachedir) which now can be used for more granular adjustments if
6271 --localstatedir is not enough to fit the particular needs. As a nice
6272 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6273 [Ralf S. Engelschall]
6275 *) Make the install root for "make install" in APACI's Makefile overrideable
6276 by package authors. This way we are even more friendly to package
6277 maintainers (especially Debian and RedHat) who build for the real prefix
6278 via "configure --prefix=/<real>" but use a different local prefix via
6279 "make root=/tmp/apache install" for rolling the package without bristling
6280 the target location on their system.
6281 [Ralf S. Engelschall]
6283 *) Workaround sed limitations in APACI's configure script by now
6284 substituting in chunks of 50 commands (because for instance HPUX's vendor
6285 sed has a limit of max. 98 commands)
6286 [Ralf S. Engelschall] PR#2136
6288 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
6289 [Ralf S. Engelschall] PR#2140
6291 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6292 RENAMING process because they are defined as pre-processor macros instead
6293 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6294 [Ralf S. Engelschall]
6296 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6297 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6298 [Ralf S. Engelschall] PR#2139
6300 *) Various bugfixes and cleanups for the APACI configure script:
6301 o fix IFS handling for _nested_ situation
6302 o fix Perl interpreter search: take first one found instead of last one
6303 o fix DSO consistency check
6304 o print error messages to stderr instead of stdout
6305 o add install-quiet for --shadow situation to Makefile stub
6306 o reduce complexity by avoiding sed-hacks for rule and module list loops
6307 [Ralf S. Engelschall]
6309 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6311 *) Make sure the input field separator (IFS) shell variable is explicitly
6312 initialized correctly before _every_ `for' loop and also restored after
6313 the loops. [Ralf S. Engelschall]
6315 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6316 `magic' files from an existing Apache installation. Because people often
6317 customize these for own MIME and content types.
6318 [Ralf S. Engelschall]
6320 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
6321 [Peter Galbavy, Ralf S. Engelschall] PR#2109
6323 *) Fix the path to the ScoreBoardFile in the install-config target, too.
6324 [Ralf S. Engelschall] PR#2105
6326 *) Let "configure" clear out the users parameters (provided as shell
6327 variables) to avoid side-effects in "src/Configure" when the user
6328 exported them (which is not needed, but some users do it).
6329 [Ralf S. Engelschall] PR#2101
6331 *) Provide backward compatibility from some old src/Configuration.tmpl
6332 parameter names to the canonical Autoconf-style shell variable names. For
6333 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
6334 but a hint message is displayed. [Ralf S. Engelschall]

6337 CGI scripts from an existing Apache installation.
6338 [Ralf S. Engelschall, Jim Jagielski] PR#2084
6340 *) Make `configure --compat' more "compatible" by first
6341 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
6342 second by making sure the "avoid-bristling-suffix" /apache is not
6343 appended to sysconfdir, datadir, localstatedir and includedir when

6355 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6357 *) If you start apache with the -S command line option it will dump
6358 out the parsed vhost settings. This is useful for folks trying
6359 to figure out what is wrong with their vhost configuration.
6360 (Other dumps may be added in the future.) [Dean Gaudet]
6362 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6363 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6366 *) Because /usr/local/apache is the default prefix the ``configure
6367 --compat'' option no longer has to set prefix, again. This way the
6368 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6370 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6371 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6372 to avoid "discard const" warnings. [Ralf S. Engelschall]
6374 *) If a specific handler is set for a file yet the request still
6375 ends up being handled by the default handler, log an error
6376 message before handling it. This catches things such as trying
6377 to use SSIs without mod_include enabled. [Marc Slemko]
6379 *) Fix error logging for the startup case where ap_log_error() still uses
6380 stderr as the target. Now the default log level is honored here, too.
6381 [Ralf S. Engelschall]
6383 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
6384 long" errors when generating the MODULES entry for src/Makefile

6387 *) Make sure src/Configure doesn't complain about the old directory
6388 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6390 Changes with Apache 1.3b6
6392 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6394 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6395 interface via the similar but proprietary HP/UX shl_xxx-style system
6396 calls. [Ralf S. Engelschall]
6398 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6399 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6400 Make. [Ralf S. Engelschall]
6402 *) ++++ THE BIG SYMBOL RENAMING ++++
6403 To avoid symbol clashes with third-party code compiled into the server,
6404 we globally applied the prefix "ap_" to the following classes of
6406 - Apache provided general functions (e.g., ap_cpystrn)
6407 - Public API functions (e.g., palloc, bgets)
6408 - Private functions which we can't make static (because of
6409 cross-object usage) but should be (e.g., new_connection)
6410 For backward source compatibility a new header file named compat.h was
6411 created which provides defines for the old symbol names and can be used
6412 by third-party module authors.
6415 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6416 problem under SVR4 is that there is no command flag to force the linker
6417 to export the global symbols of the httpd executable therewith they are
6418 available to the DSO's. Instead of problematic hacks like creating a
6419 dummy.so file (containing dummy references to all global symbols) the
6420 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6421 Placing the Apache core code itself into a DSO library named libhttpd.so.
6422 This way the global symbols _HAVE_ to be exported and thus are available
6423 to any manually loaded DSO's under runtime. To reduce the impact to the
6424 user to null we go even further and create a stub httpd executable which
6425 automatically keeps track of the DSO library loading itself and thus
6426 hides the complete mechanism from the user. Although the generation of
6427 this DSO library is automatically triggered for platforms which
6428 essentially need it (mostly all SVR4-derivates) it can be also enabled
6429 manually via the Rule SHARED_CORE. This can be interesting in the future
6430 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6431 features like graceful upgrades, or whatever.
6432 [Ralf S. Engelschall, Martin Kraemer]
6434 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6436 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6437 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6438 conventions while "clean" removes only stuff created by "all" targets,
6439 "distclean" additionally removes the stuff from the configuration
6440 process. This way "make distclean" (hence the name) provides a fresh
6441 source tree as it was for distribution.
6442 [Ralf S. Engelschall]
6444 *) Allow top-level (APACI) Makefile to break on build errors
6445 the same way the src/ subtree Makefiles breaks on them by replacing the
6446 initial APACI sed-subdir-display-kludge with a more clean
6447 variable-passing-solution: variable SDP can optionally hold the subdir
6448 prefix which is consistently used for displaying the subdir movement.
6449 This way even the top-level Makefile can stop correctly on errors as the
6450 user expects. [Ralf S. Engelschall]
6452 *) Fixed ordering of argument checks for RewriteBase directive.
6453 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6455 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of

6465 *) Add documentation file and src/Configuration.tmpl entry for the
6466 experimental mod_mmap_static module. Because although it is and marked as
6467 an experimental one it is distributed and thus should be documented and
6468 prepared for configuration the same way as all others modules.
6469 [Ralf S. Engelschall]
6471 *) Add query (-q) option to apxs support tool to be able to manually query
6472 specific settings from apxs. This is needed for instance when you
6473 manually want to access Apache's header files and you need to assemble
6474 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6475 [Ralf S. Engelschall]
6477 *) Now src/Configure uses a fallback strategy for the shared object support
6478 on platforms where no explicit information is available: If a Perl
6479 installation exists we ask it about its shared object support and if it's
6480 the dlopen-style one we shamelessly guess the compiler and linker flags
6481 for creating shared objects from Perls knowledge. Of course, the user is
6482 warning about what we are doing and informed that he should send us
6483 the guessed flags when they work. [Ralf S. Engelschall]
6485 *) Provide APACI --without-support option to be able to disable the build
6486 and installation of the support tools from the src/support/ area.
6487 Although its useful to have these installed per default we should provide
6488 a way to compile and install without them for backward-compatibility.
6489 [Ralf S. Engelschall]
6491 *) Add of the new APache eXtenSion (apxs) support tool for building and
6492 installing modules into an _already installed_ Apache package through the
6493 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6494 this approach actually doesn't need the Apache source tree. The
6495 (APACI-installed) server package is enough, because this now includes the
6496 Apache C header files (PREFIX/include) and the new APXS tool
6497 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6498 module authors to build their Apache modules _OUTSIDE_ the Apache source
6499 tree while avoiding them to fiddle around with the totally platform
6500 dependend way of compiling DSO files. The tool supports all ranges of
6501 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6502 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6503 on-the-fly generate a minimalistic Makefile and sample module for the
6504 first step to provide both a quick success event and to demonstrate the
6505 APXS mechanism to module authors. [Ralf S. Engelschall]
6507 *) Fix core dumps in use of CONNECT in proxy.
6508 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6510 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6511 so that users have examples of how CustomLog can be used.
6514 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6515 the Apache distribution tree. Until Apache 1.3 there was no real
6516 out-of-the-box batch-capable build and installation procedure for the
6517 complete Apache package. This is now provided by a top-level "configure"
6518 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6519 to provide a GNU Autoconf-style frontend which is capable to both drive
6520 the old src/Configure stuff in batch and additionally installs the
6521 package with a GNU-conforming directory layout. Any options from the old
6522 configuration scheme are available plus a lot of new options for flexibly
6523 customizing Apache. [Ralf S. Engelschall]
6525 *) The floating point ap_snprintf code wasn't threadsafe.
6526 Had to remove the HAVE_CVT macro in order to do threadsafe
6527 calling of the ?cvt() floating point routines. [Dean Gaudet]
6529 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6531 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
6532 [Jim Jagielski] PR#1901
6534 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6535 Configure knows which CC we are using. [Jim Jagielski]
6537 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6538 was defined in a parent directory. [Lars Eilebrecht]
6540 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6541 a generic printf-style routine that can call arbitrary output
6542 routines. Use this to replace http_bprintf.c. Add new routines
6543 psprintf(), pvsprintf() which allocate the exact amount of memory
6544 required for a string from a pool. Use psprintf() to clean up
6545 various bits of code which used ap_snprintf()/pstrdup().
6548 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6549 ap_snprintf() has different semantics and formatting codes than
6550 snprintf(). [Dean Gaudet]
6552 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6553 is necessary on at least Solaris where the /etc/rc?.d scripts
6554 are run with these signals ignored, and "SIG_IGN" settings are
6555 maintained across exec().
6556 [Rein Tollevik <reint@sys.sol.no>] PR#2009
6558 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was

6562 *) Fix the proxy pass-through feature of mod_rewrite for the case of
6563 existing QUERY_STRING now that mod_proxy was recently changed because of
6564 the new URL parsing stuff. [Ralf S. Engelschall]
6566 *) A few changes to scoreboard definitions which helps gcc generate
6567 better code. [Dean Gaudet]
6569 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
6570 be a signed bitfield. So mark a few bitfields as signed to
6571 ensure correct code. [Dean Gaudet]
6573 *) The default for HostnameLookups was changed to Off, but there
6574 was a problem and it wasn't taking effect. [Dean Gaudet]
6576 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
6579 *) After a SIGHUP the listening sockets in the parent weren't
6580 properly marked for closure on fork().
6581 [Jürgen Keil <jk@tools.de>] PR#2000
6583 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6584 therefore not exposed to %2F -> '/' translations and 2) the request
6585 is a proxy request, so we're not dealing with a local resource anyway.
6586 Without this, the proxy would fail to work for any URL's with
6587 %2f in them (occurs quite often in
6588 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6590 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6592 *) Make the shared object compilation command more portable by avoiding
6593 the direct combination of `-c' & `-o' which is not honored by some
6594 compilers like UnixWare's cc. [Ralf S. Engelschall]
6596 *) WIN32: the proxy was creating filenames missing the last four
6597 characters. While this normally doesn't stop anything from
6598 working, it can result in extra collisions.
6599 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
6601 *) Now mod_proxy uses the response string (in addition to the response status
6602 code) from the already used FTP SIZE command to setup the Content-Length
6603 header if available. [Ralf S. Engelschall] PR#1183
6605 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6606 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6607 name was really too generic, added documentation for this directive to
6608 the mod_proxy.html and corrected the hyperlink to it in the
6609 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
6611 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6612 faster [Martin Kraemer]
6614 *) Make Configure die when you give it an unknown command switch.
6617 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6618 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6619 and per default compiled support programs have manual pages - just to
6620 document our stuff a little bit more and to be able to do really
6621 Unix-like installations ;-) [Ralf S. Engelschall]
6623 *) Major cleanups to the Configure script to make it and its generated
6624 Makefiles again readable and maintainable: add SRCDIR option, removed
6625 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6626 generated sections, consequently added Makefile headers with inheritance
6627 information, added subdir movement messages for easier following where
6628 the build process currently stays (more verbose then standard Make, less
6629 verbose than GNU make), same style to comments in the Configure script,
6630 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6632 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6633 from the ZeusBench benchmarking program and can be used to determine the
6634 response performance of an Apache installation. This version is
6635 officially licensed with Zeus Technology, Ltd. See the license agreement
6636 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
6637 [Ralf S. Engelschall]
6639 *) API: Various core functions that are definately not part of the API
6640 have been made static, and a few have been marked API_EXPORT. Still
6641 more have been marked CORE_EXPORT and are not intended for general
6642 use by modules. [Doug MacEachern, Dean Gaudet]
6644 *) mod_proxy was not clearing the Proxy-Connection header from
6645 requests; now it does. This did not violate any spec, however
6646 causes poor interactions when you are talking to remote proxies.
6647 [Marc Slemko] PR#1741
6649 *) Various cleanups to the command line interface and manual pages.
6650 [Ralf S. Engelschall]
6652 *) cfg_getline() was not properly handling lines that did not end
6653 with a line termination character. [Marc Slemko] PR#1869, 1909
6655 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6657 *) Clean up some undocumented behavior of mod_setenvif related to
6658 "merging" two SetEnvIf directives when they match the same header
6659 and regex. Document that mod_setenvif will perform comparisons in
6660 the order they appear in the config file. Optimize mod_setenvif by
6661 doing more work at config time rather than at runtime.
6664 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6665 to allow for modules to overrule them and to reduce redefinition
6666 warnings [Jim Jagielski]
6668 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6671 *) Making the hard-coded cross-module function call mime_find_ct() (from
6672 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6673 checking is really called even for proxy requests except for URLs with
6674 HTTP schemes (because there we can optimize by not running the type
6675 checking hooks due to the fact that the proxy gets the MIME Content-type
6676 from the remote host later). This change cleans up mod_mime by removing
6677 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6678 especially unbundles mod_proxy and mod_mime. This way they both now can
6679 be compiled as shared objects and are no longer tied together.
6680 [Ralf S. Engelschall]
6682 *) util.c cleanup and speedup. [Dean Gaudet]
6684 *) API: Clarification, pstrndup() will always copy n bytes of the source
6685 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6687 *) Mark module command_rec and handler_rec structures const so that they
6688 end up in the read-only data section (and are friendlier to systems
6689 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6691 *) Add check to the "Port" directive to make sure the specified
6692 port is in the appropriate range. [Ben Hyde]
6694 *) Performance improvements to invoke_handler().
6695 [Dmitry Khrustalev <dima@bog.msu.su>]
6697 *) Added support for building shared objects even for library-style modules
6698 (which are built from more than one object file). This now provides the
6699 ability to build mod_proxy as a shared object module. Additionally
6700 modules like mod_example are now also supported for shared object
6701 building because the generated Makefiles now no longer assume there is at
6702 least one statically linked module. [Ralf S. Engelschall]
6704 *) API: Clarify usage of content_type, handler, content_encoding,
6705 content_language and content_languages fields in request_rec. They
6706 must always be lowercased; and the strings pointed to shouldn't
6707 be modified (you must copy them to modify them). Fix a few bugs
6708 related to this. [Dean Gaudet]
6710 *) API: Clarification: except for RAW_ARGS, all command handlers can
6711 treat the char * parameters as permanent, and modifiable. There
6712 is no need to pstrdup() them. Clean up some needless pstrdup().
6715 *) Now mod_so keeps track of which module shared objects with which names
6716 are loaded and thus avoids multiple loading and unloading and irritating
6717 error_log messages. [Ralf S. Engelschall]
6719 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6720 environment variable in the apache core. But that tweaking interferes
6721 with mod_setenv. So don't tweak if the user has specified an explicit
6722 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6724 *) rputs() did not calculate r->sent_bodyct properly.
6725 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6727 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6728 name, or left unset if this value is unavailable. Apache was setting
6729 it to the IP address when unavailable.
6730 [Tony Finch <fanf@demon.net>] PR#1925
6732 *) Various improvements to the configuration and build support for compiling
6733 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6734 OSF1 support with GCC and vendor compilers was added. This way shared
6735 object support is now provided out-of-the-box for FreeBSD, Linux,
6736 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6737 [Ralf S. Engelschall]
6739 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6740 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6741 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6743 *) Fix one more special locking problem for RewriteMap programs in
6744 mod_rewrite: According to the documentation of flock(), "Locks are on
6745 files, not file descriptors. That is, file descriptors duplicated
6746 through dup(2) or fork(2) do not result in multiple instances of a lock,
6747 but rather multiple references to a single lock. If a process holding a
6748 lock on a file forks and the child explicitly unlocks the file, the
6749 parent will lose its lock.". To overcome this we have to make sure the
6750 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6751 the case by opening it in the child_init instead of the module_init API
6752 hook. [Ralf S. Engelschall] PR#1029
6754 *) Change to Location and LocationMatch semantics. LocationMatch no
6755 longer lets a single slash match multiple adjacent slashes in the
6756 URL. This change is for consistency with RewriteRule and
6757 AliasMatch. Multiple slashes have meaning in URLs that they do
6758 not have in (some) filesystems. Location on the other hand can
6759 be considered a shorthand for a more complicated regex, and it
6760 does match multiple slashes with a single slash -- which is
6761 also consistent with the Alias directive.
6762 [Dean Gaudet] related PR#1440
6764 *) Fix bug with mod_mime_magic causing certain files, including files
6765 of length 0, to result in no response from the server.
6768 *) The Configure script now generates src/include/ap_config.h which
6769 contains the set of defines used when Apache is compiled on a platform.
6770 This file can then be included by external modules before including
6771 any Apache header files in case they are being built separately from
6772 Apache. Along with this change, a couple of minor changes were
6773 made to make Apache's #defines coexist peacefully with any autoconf
6774 defines an external module might have. [Rasmus Lerdorf]
6776 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6777 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6778 chance by the API to initialize its per-server configuration and thus
6779 receives the wrong one from the main server. This is now avoided by
6780 remembering the server together with the config structure while
6781 configuring and later assuming there is no config when we see a
6782 difference between the remembered server and the one calling us.
6783 [Ralf S. Engelschall] PR#1790
6785 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6786 is automatically disabled under configure time when the dbm_xxx functions
6787 are not available. Second, two heavy source code errors in the DBM
6788 support code were fixed. This makes DBM RewriteMap's usable again after
6789 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6791 *) Now all configuration files support Unix-style line-continuation via
6792 the trailing backslash ("\") character. This enables us to write down
6793 complex or just very long directives in a more readable way. The
6794 backslash character has to be really the last character before the
6795 newline and it has not been prefixed by another (escaping) backslash.

6801 *) To deal with modules being compiled and [dynamically] linked
6802 at a different time from the core, the SERVER_VERSION and
6803 SERVER_BUILT symbols have been abstracted through the new
6804 API routines apapi_get_server_version() and apapi_get_server_built().
6807 *) WIN32: Preserve trailing slash in canonical path (and hence
6808 in PATH_INFO). [Paul Sutton, Ben Laurie]
6810 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6811 depending on the rev of Solaris and what mixture of modules
6812 are in use. So it has been disabled, and Solaris is back to
6813 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6814 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6815 up static content only servers. Or it may fail unpredictably.

6818 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6821 *) API: Rewrite of absoluteURI handling, and in particular how
6822 absoluteURIs match vhosts. Unless a request is a proxy request, a
6823 "http://host" url is treated as if a similar "Host:" header had been
6824 supplied. This change was made to support future HTTP/1.x protocols
6825 which may require clients to send absoluteURIs for all requests.
6827 In order to achieve this change subtle changes were made to the API. In a
6828 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6829 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6830 by the core, modules must set it during the post_read_request or
6831 translate_names phase.
6833 Plus changes to the virtualhost test suite for absoluteURI testing.
6835 This fixes several bugs with the proxy proxying requests to vhosts
6836 managed by the same httpd.
6839 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6840 code from mod_rewrite. The vhost matching is now performed by a
6841 globally available function matches_request_vhost(). [Dean Gaudet]

6857 *) API: A new source module main/util_uri.c; It contains a routine
6858 parse_uri_components() and friends which breaks a URI into its component
6859 parts. These parts are stored in a uri_components structure called
6860 parsed_uri within each request_rec, and are available to all modules.
6861 Additionally, an unparse routine is supplied which re-assembles the URI
6862 components back to an URI, optionally hiding the username:password@ part
6863 from ftp proxy requests, and other useful routines. Within the structure,
6864 you find on a ready-for-use basis:
6865 scheme; /* scheme ("http"/"ftp"/...) */
6866 hostinfo; /* combined [user[:password]@]host[:port] */
6867 user; /* user name, as in http://user:passwd@host:port/ */
6868 password; /* password, as in http://user:passwd@host:port/ */
6869 hostname; /* hostname from URI (or from Host: header) */
6870 port_str; /* port string (integer representation is in "port") */
6871 path; /* the request path (or "/" if only scheme://host was given) */
6872 query; /* Everything after a '?' in the path, if present */
6873 fragment; /* Trailing "#fragment" string, if present */
6874 This is meant to serve as the platform for *BIG* savings in
6875 code complexity for the proxy module (and maybe the vhost logic).
6878 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6879 ${map:key}) available for all location where a string is created in
6880 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

6882 possible expansions are consequently usable at all string creation
6883 locations. [Ralf S. Engelschall]
6885 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6886 and not 1) and the per-virtual-server merging of directives. Now all
6887 directives except `RewriteEngine' and `RewriteOption' are either
6888 completely overridden (default) or completely inherited (when
6889 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6898 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6899 (like SunOS and FreeBSD) which don't accept the locking of pipes

6919 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6920 type but with a special post-processing for the looked-up value: It
6921 parses it into alternatives according to `|' chars and then only one
6922 particular alternative is chosen randomly (this is an essential
6923 functionality needed for balancing between backend-servers when using
6924 Apache as a Reverse Proxy. The looked up value here is a list of
6925 servers). Second, `int' with the built-in maps named `tolower' and
6926 `toupper' which can be used to map URL parts to a fixed case (this is an
6927 essential feature to fix the case of server names when doing mass
6928 virtual-hosting with the help of mod_rewrite instead of using
6929 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from

6932 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6933 This directive lets Apache adjust the URL in Location-headers on HTTP
6934 redirect responses sent by the remote server. This way the virtually
6935 mapped area is no longer left on redirects and thus by-passed which is
6936 especially essential when running Apache as a reverse proxy.

6942 *) Apache will, when started with the -X (single process) debugging flag,
6943 honor the SIGINT or SIGQUIT signals again now. This capability got lost
6944 a while ago during OS/2 signal handling changes.
6946 *) [PORT] Work around the fact that NeXT runs on more than the

6954 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
6955 In particular the handlers could trigger themselves into an infinite
6956 loop if RLimitMem was used with a small amount of memory -- too small
6957 for the signal stack frame to be set up. [Dean Gaudet]

6971 *) mod_info would occasionally produce an unpaired <tt> in its
6972 output. Fixed. [Martin Kraemer]
6974 *) By default AIX binds a process (and it's children) to a single
6975 processor. httpd children now unbind themselves from that cpu
6976 and re-bind to one selected at random via bindprocessor()
6979 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
6980 effect. Work around it by using RLIMIT_AS for the RLimitMEM

6983 *) mod_mime_magic error message should indicate the filename when
6984 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
6986 *) Previously Apache would permit </Files> to end <FilesMatch> (and
6987 similary for Location and Directory), now this is diagnosed as an
6988 error. Improve error messages for mismatched sections (<Files>,
6989 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).

7037 Changes with Apache 1.3b4
7039 *) The module structure was modified to include a *dynamic_load_handle
7040 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
7041 has been bumped accordingly. [Paul Sutton]
7043 *) All BrowserMatch directives mentioned in
7044 htdocs/manual/known_client_problems.html are in the default
7045 configuration files. [Lars Eilebrecht]
7047 *) MiNT port update. [Jan Paul Schmidt]
7049 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
7050 equivalent, similarly for x-compress and compress. Apache
7051 now ignores a leading x- when comparing encodings. It also
7052 preserves the encoding the client requests (for example if
7053 it requests x-gzip, then Apache will respond with x-gzip
7054 in the Content-Encoding header).
7055 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
7057 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
7059 *) Added mod_so module to support dynamic loading of modules on Unix
7060 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
7061 instead of AddModule in Configuration to build shared modules
7062 [Sameer Parekh, Paul Sutton]
7064 *) Minor cleanups to r->finfo handling in some modules.
7067 *) Abstract read()/write() to ap_read()/ap_write().
7068 Makes it easier to add other types of IO code such as SFIO.
7071 *) API: Generalize default_port manipulations to make support of
7072 different protocols easier. [Ben Laurie, Randy Terbush]
7074 *) There are many cases where users do not want Apache to form
7075 self-referential urls using the "canonical" ServerName and Port.
7076 The new UseCanonicalName directive (default on), if set to off
7077 will cause Apache to use the client-supplied hostname and port.
7078 API: Part of this change required a change to the construct_url()
7079 prototype; and the addition of get_server_name() and
7081 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
7082 PR#315, 459, 485, 1433
7084 *) Yet another rearrangement of the source tree.. now all the common
7085 header files are in the src/include directory. The -Imain -Iap
7086 references in Makefiles have been changed to the simpler -Iinclude
7087 instead. In addition to simplifying the build a little bit, this
7088 also makes it clear when a module is referencing something in a
7089 other than kosher manner (e.g., the proxy including mod_mime.h).
7090 Module-private header files (the proxy, mod_mime, the regex library,
7091 and mod_rewrite) have not been moved to src/include; nor have
7092 the OS-abstraction files. [Ken Coar]
7094 *) Fix a bug where r->hostname didn't have the :port stripped
7095 from it. [Dean Gaudet]
7097 *) Tweaked the headers_out table size, and the subprocess_env
7098 table size guess in rename_original_environment(). Added
7099 MAKE_TABLE_PROFILE which can help discover make_table()
7100 calls that use too small an initial guess, see alloc.c.
7103 *) Options and AllowOverride weren't properly merging in the main
7104 server setting inside vhosts (only an issue when you have no
7105 <Directory> or other section containing an Options that affects
7106 a request). Options +foo or -foo in the main_server wouldn't
7107 affect the main_server's lookup defaults. [Dean Gaudet]
7109 *) Variable 'cwd' was being used pointlessly before being set.
7112 *) r->allowed handling cleaned up in the standard modules.
7115 *) Some case-sensitivity issues cleaned up to be consistent with
7116 RFC2068. [Dean Gaudet]
7118 *) SIGURG doesn't exist everywhere.
7119 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7121 *) mod_unique_id was erroneously generating a second unique id when
7122 an internal redirect occured. Such redirects occur, for example,
7123 when processing a DirectoryIndex match. [Dean Gaudet]
7125 *) API: table_add, table_merge, and table_set include implicit pstrdup()
7126 of the key and value. But in many cases this is not required
7127 because the key/value is a constant, or the value has been built
7128 by pstrcat() or other similar means. New routines table_addn,
7129 table_mergen, and table_setn have been added to the API, these
7130 routines do not pstrdup() their arguments. The core code and
7131 standard modules were changed to take advantage of these routines.
7132 The resulting server is up to 20% faster in some situations.
7134 Note that it is easy to get code subtly wrong if you pass a key/value
7135 which is in a pool other than the pool of the table. The only
7136 safe thing to do is to pass key/values which are in the pool of
7137 the table, or in one of the ancestors of the pool of the table.
7138 i.e. if the table is part of a subrequest, a value from the main
7139 request's pool is OK since the subrequest pool is a sub_pool of the
7140 main request's pool (and therefore has a lifespan at most as long as
7141 the main pool). There is debugging code which can detect improper
7142 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
7143 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
7145 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
7146 which don't exist on disk more gracefully; handles vhosts properly.
7147 Update documentation to reflect the code -- if there's no
7148 MimeMagicFile directive then the module is not enabled.
7151 *) PORT: Some older *nix dialects cannot automatically start scripts
7152 which begin with a #! interpreter line (the shell starts the scripts
7153 appropriately on these platforms). Apache now supports starting of
7154 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
7155 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
7158 *) API: "typedef array_header table" removed from alloc.h, folks should
7159 have been writing to use table as if it were an opaque type, but even
7160 some standard modules got this wrong. By changing the definition
7161 to "typedef struct table table" module authors will receive compile
7162 time warnings that they're doing the wrong thing. This change
7163 facilitates future changes with more sophisticated table
7164 structures. Specifically, module authors should be using table_elts()
7165 to get access to an array_header * for the table. [Dean Gaudet]
7167 *) API: Renamed new_connection() to avoid namespace collision with LDAP
7168 library routines. [Ken Coar, Rasmus Lerdorf]
7170 *) WIN32: mod_speling is now available on the Win32 platform.
7173 *) For clarity the following compile time definition was changed:
7175 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
7177 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
7178 and not be a general notice that the OS has mmap(). Now the
7179 HAVE_MMAP/SHMGET #defines strictly are informational that the
7180 OS has that method of shared memory; the type to use for
7181 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
7182 and USE_SHMGET_SCOREBOARD). This allows outside modules to
7183 determine if shared memory is available and allows Apache
7184 to determine the best method to use for the scoreboard.
7187 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
7188 as do various earlier versions. It should be safe on all versions.
7189 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
7190 the slack code. A few other cleanups for Unixware.

7193 *) PORT: A/UX can handle single-listen accepts without mutex
7194 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
7196 *) When die() happens we need to eat any request body if one exists.
7197 Otherwise we can't continue with a keepalive session. This shows up
7198 as a POST problem with MSIE 4.0, typically against pages which are
7199 authenticated. [Roy Fielding] PR#1399
7201 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
7202 header will be passed to CGIs. This is generally a security hole, so
7203 it's not a default. [Marc Slemko] PR#549
7205 *) Fix Y2K problem with date printing in suexec log.

7208 *) WIN32 deserves a pid file. [Ben Hyde]
7210 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
7212 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
7213 The choice of flock vs. fcntl was made based on timings which showed that
7214 even on non-NFS, non-exported filesystems fcntl() was an order of
7215 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7216 that single socket users will see no difference. [Dean Gaudet] PR#467
7218 *) "File does not exist" error message was erroneously including the
7219 errno. [Marc Slemko]
7221 *) Improve the warning message generated when a client drops the
7222 connection (hits stop button, etc.) during a send. [Roy Fielding]
7224 *) Defining GPROF will disable profiling in the parent and enable it
7225 in the children. If you're profiling under Linux this is pretty much
7226 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
7228 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
7231 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
7232 gcc functionality. Work around it.

7235 *) Some linkers complain when .o files contain no functions.
7236 [Keith Severson <keith@sssd.navy.mil>] PR#1614
7238 *) Some const declarations in mod_imap.c that were added for debugging
7239 purposes caused some compilers heartburn without adding any
7240 significant value, so they've been removed. [Ken Coar]
7242 *) The src/main/*.h header files have had #ifndef wrappers added to
7243 insulate them against duplicate calls if they get included through
7244 multiple paths (e.g., in .c files as well as other .h files).
7247 *) The libap routines now have a header file for their prototypes,
7248 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
7250 *) mod_autoindex with a plaintext header file would emit the <PRE>
7251 start-tag before the HTML preamble, rather than after the preamble
7252 but before the header file contents. [John Van Essen <jve@gamers.org>]
7255 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7256 only an issue on systems without a MAXDNAME define or where
7257 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7259 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7260 is used to read various types of files such as htaccess and
7261 htpasswd files. [Marc Slemko]
7263 *) SECURITY: Ensure that the buffer returned by ht_time is always
7264 properly null terminated. [Marc Slemko]
7266 *) The "Connection" header could be sent back with multiple "close"
7267 tokens. Not an error, but a waste.
7268 [Ronald.Tschalaer@psi.ch] PR#1683
7270 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
7271 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
7273 *) "basic" auth needs a case-insensitive comparison.
7274 [Ronald.Tschalaer@psi.ch] PR#1666
7276 *) For maximum portability, the environment passed to CGIs should
7277 only contain variables whose names match the regex
7278 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
7279 underscores over any character outside the regex. This
7280 affects HTTP_* variables, in a way that should be backward
7281 compatible for all the standard headers; and affects variables
7282 set with SetEnv/BrowserMatch and similar directives.
7285 *) mod_speling returned incorrect HREF's when an ambigous match
7286 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
7287 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
7289 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
7290 (the Siemens BS2000/OSD family) in the POSIX subsystem
7293 *) PORT: Fix problem killing children when terminating. Allow ^C
7294 to shut down the server. [Brian Havard]
7296 *) pstrdup() is implicit in calls to table_* functions, so there's
7297 no need to do it before calling. Clean up a few cases.
7298 [Marc Slemko, Dean Gaudet]
7300 *) new -C and -c command line arguments

7311 [Marc Slemko] PR#1591
7313 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to

7318 possible buffer overflows and a possible infinite loop.
7319 [Dean Gaudet, Marc Slemko]
7321 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7322 including fixing a possible buffer overflow. [Dean Gaudet]
7324 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
7325 (connections are not dropped). Code can handle graceful restarts
7326 (but there is as yet no way to signal this to Apache). Various
7327 other cleanups. [Paul Sutton]
7329 *) The aplog_error changes specific to 1.3 introduced a buffer
7330 overrun in the (now legacy) log_printf function. Fixed.
7333 *) mod_digest didn't properly deal with proxy authentication. It
7334 also lacked a case-insensitive comparision of the "Digest"
7335 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
7337 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
7339 *) A few cleanups in mod_info to make it thread-safe, and remove an

7346 ap_cpystrn() for performance and functionality reasons.

7363 *) Interim (slow) fix for p->sub_pool critical sections in
7364 alloc.c (affects win32 only). [Ben Hyde]
7366 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
7368 *) send_fd_length() did not calculate total_bytes_sent properly.
7369 [Ben Reser <breser@regnow.com>] PR#1366
7371 *) The bputc() macro was not properly integrated with the chunking
7372 code; in many cases modules using bputc() could cause completely
7373 bogus chunked output. (Typically this will show up as problems
7374 with Internet Explorer 4.0 reading a page, but other browsers
7375 having no problem.) [Dean Gaudet]
7377 *) Create LARGE_WRITE_THRESHOLD define which determines how many
7378 bytes have to be supplied to bwrite() before it will consider
7379 doing a writev() to assemble multiple buffers in one system
7380 call. This is critical for modules such as mod_include,
7381 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
7382 strings in some cases. The result would be extra effort
7383 setting up writev(), and in many cases extra effort building
7384 chunks. The default is 31, it can be overriden at compile
7387 *) Move the gid switching code into the child so that log files
7388 and pid files are opened with the root gid.

7395 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
7396 so the functionality is available to applications other than the
7397 server itself (like the src/support tools). [Ken Coar]
7399 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
7400 the libap consolidation work. [Ken Coar]
7402 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not

7479 *) Add a "-V" command line flag to the httpd binary. This
7480 flag shows some of the defines that Apache was compiled with.
7481 It is useful for debugging purposes. [Martin Kraemer]
7483 *) Start separating the ap_*() routines into their own library, so they
7484 can be used by items in src/support among other things.

7487 *) Give a more informative error when no AuthType is set.
7490 *) Remove strtoul() use from mod_proxy because it isn't available
7491 on all platforms. [Marc Slemko] PR#1214
7493 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
7494 This turns out to be a bug in Winsock - select() doesn't always
7495 return the correct status. [Ben Laurie]
7497 *) Directives owned by http_core can now use the new check_cmd_context()
7498 routine to ensure that they're not being used within a container
7499 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
7501 *) PORT: Recent changes made it necessary to add explicit prototype
7502 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
7504 *) It was necessary to distinguish between resources which are
7505 allocated in the parent, for cleanup in the parent, and resources
7506 which are allocated in each child, for cleanup in each child.
7507 A new pool was created which is passed to the module child_init
7508 and child_exit functions; modules are free to register per-child
7509 cleanups there. This fixes a bug with reliable piped logs.
7512 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
7513 unless it was also doing FancyIndexes, but it displayed the
7514 HeaderName file at the top under all circumstances. It now shows
7515 the ReadmeName file for simple indices, too, as it should.
7518 *) http_core was mmap()ing even in cases where it wasn't going to
7519 read the file. [Ben Hyde <bhyde@gensym.com>]
7521 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
7522 Now the rewriting engine (the heart of mod_rewrite) is organized more
7523 straight-forward, first time well documented and reduced to the really
7524 essential parts. All redundant cases were stripped off and processing now
7525 is the same for both per-server and per-directory context with only a
7526 minimum difference (the prefix stripping in per-dir context). As a
7527 side-effect some subtle restrictions and two recently discovered problems
7528 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
7529 context and restrictions on the substitution URL on redirects.
7530 Additionally some minor source cleanups were done.

7537 *) If ap_slack fails to allocate above the low slack line it's a good
7538 indication that further problems will occur; it's a better indication
7539 than many external libraries give us when we actually run out of
7540 descriptors. So report it to the user once per restart.

7685 Changes with Apache 1.3b2 (there is no 1.3b1)
7687 *) TestCompile was not passing $LIBS [Dean Gaudet]
7689 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7692 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7693 rudimentary memory debugger which can be used on live servers with
7694 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7695 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7696 and free() for each object. This is far more expensive and should
7697 only be used for testing with tools such as Electric Fence and
7698 Purify. See main/alloc.c for more details. [Dean Gaudet]
7700 *) Configure uses a sh trap and didn't set its exitcode properly.
7701 [Dean Gaudet] PR#1159
7703 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7704 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7705 From a given ip:port, regardless what the Host: header is, you can
7706 only reach the vhosts defined on that ip:port. The precedence of
7707 vhosts was reversed to match other precedences in the config --
7708 the earlier vhosts override the later vhosts. All vhost matching was
7709 moved into http_vhost.[ch]. [Dean Gaudet]
7711 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7712 be used for whatever reason is appropriate (i.e. format() warnings
7713 for printf style functions). Both are enabled only with
7714 gcc >= 2.7.x (so that we have fewer support issues with older
7715 versions). [Dean Gaudet]
7717 *) Fix support for Proxy Authentication (we were testing the response
7718 status too early). [Marc Slemko]
7720 *) CoreDumpDirectory directive directs where the core file is

7725 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7727 *) When booting, apache will now detach itself from stdin, stdout,
7728 and stderr. stderr will not be detached until after the config
7729 files have been read so you will be able to see initial error
7730 messages. After that all errors are logged in the error_log.
7731 This makes it more convenient to start apache via rsh, ssh,
7732 or crontabs. [Dean Gaudet] PR#523
7734 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7735 Also removed the auto-generated link to www.apache.org that was the
7736 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7738 *) send_fb would not detect aborted connections in some situations.
7741 *) mod_include would use uninitialized data when parsing certain

7744 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7746 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7748 *) mod_autoindex improperly counted &escapes; as more than one
7749 character in the description. It also improperly truncated
7750 descriptions that were exactly the maximum length.
7753 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7754 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7757 *) mod_include now uses symbolic names to check for request success
7758 and return HTTP errors, and correctly handles all types of
7759 redirections (previously it only did temporary redirect correctly).
7760 [Ken Coar, Roy Fielding]
7762 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7763 r->filename. Since those two are meant to be in sync with each other

7776 *) Fixed error in proxy_util.c when looping through multiple host IP
7777 addresses. [Lars Eilebrecht] PR#974
7779 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7780 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7781 bytes before writing, but it will never split a log entry across a
7782 buffer boundary. [Dean Gaudet]
7784 *) API: the short_score record has been split into two pieces, one which
7785 the parent writes on, and one which the child writes on. As part of
7786 this change the get_scoreboard_info() function was removed, and
7787 scoreboard_image was exported. This change fixes a race condition
7788 in file based scoreboard systems, and speeds up changes involving the
7789 scoreboard in earlier 1.3 development. [Dean Gaudet]
7791 *) API: New register_other_child() API (see http_main.h) which allows
7792 modules to register children with the parent for maintenance. It
7793 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7795 *) API: New piped_log API (see http_log.h) which implements piped logs,
7796 and will use register_other_child to implement reliable piped logs
7797 when it is available. The reliable piped logs part can be disabled
7798 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7799 logs is only available on Unix. [Dean Gaudet]
7801 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7802 meets_conditions(). This allows conditional HTTP selection to be
7803 handled separately from the storing of the header fields, and provides
7804 the ability for CGIs to set their own ETags for conditional checking.
7805 [Ken Coar, Roy Fielding] PR#895
7807 *) Changes to mod_log_config to allow naming of format strings.
7808 Format nicknames are defined with "LogFormat fmt nickname", and can
7809 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7812 *) New module, "mod_speling", which can help find files even when
7813 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7815 *) API: New function child_terminate() triggers the child process to
7816 exit, while allowing the child finish what it needs to for the
7817 current request first.
7818 [Doug MacEachern, Alexei Kosut]
7820 *) Windows now defaults to using full status reports with mod_status.
7821 [Alexei Kosut] PR #1094
7823 *) *Really* disable all mod_rewrite operations if the engine is off.
7824 Some things (like RewriteMaps) were checked/performed even if they
7825 weren't supposed to be. [Ken Coar] PR #991
7827 *) Implement a new timer scheme which eliminates the need to call alarm() all
7828 the time. Instead a counter in the scoreboard for each child is used to
7829 show when the child has made forward progress. The parent samples this
7830 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7831 progress has been made in the timeout period. This reduces the static
7832 request best-case syscall count to 22 from 29. This scheme is only
7833 used by systems with memory-based scoreboards. [Dean Gaudet]
7835 *) The proxy now properly handles CONNECT requests which are sent
7836 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7838 *) A script called apachectl has been added to the support
7839 directory. This script allows you to do things such as
7840 "apachectl start" and "apachectl restart" from the command
7843 *) Modules and core routines are now put into libraries, which
7844 simplifies the link line tremendously (among other advantages).
7847 *) Some of the MD5 names defined in Apache have been renamed to have
7848 an `ap_' prefix to avoid conflicts with routines supplied by
7849 external libraries. [Ken Coar]
7851 *) Removal of mod_auth_msql.c from the distribution. There are many
7852 other options for databases today. Rather than offer one option,
7853 offer none at this time. mod_auth_msql and other SQL database
7854 authentication modules can be found at the Apache Module Registry.
7855 http://modules.apache.org/ It would be nice to offer a generic
7856 mod_auth_sql option in the near future.
7858 *) PORT: BeOS support added [Alexei Kosut]
7860 *) Configure no longer accepts the -make option, since it creates
7861 Makefile on the fly based on Makefile.tmpl and Configuration.
7863 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7864 of forcibly killing off all its processes and exiting without
7865 cleaning up. [Alexei Kosut]
7867 *) API: A new field in the request_rec, r->mtime, has been added to
7868 avoid gratuitous parsing of date strings. It is intended to hold
7869 the last-modified date of the resource (if applicable). An
7870 update_mtime() routine has also been added to advance it if
7871 appropriate. [Roy Fielding, Ken Coar]
7873 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7874 deny access to the directory with a HTTP_FORBIDDEN. The previous
7875 behavior was to ignore the htaccess file if it could not be read.
7876 This change may make some setups with unreadable htaccess files
7877 stop working. [Marc Slemko] PR#817
7879 *) Add aplog_error() providing a mechanism to define levels of
7880 verbosity to the server error logging. This addition also provides
7881 the ability to log errors using syslogd. Error logging is configurable
7882 on a per-server basis using the LogLevel directive. Conversion
7883 of log_*() in progress. [Randy Terbush]
7885 *) Further enhance aplog_error() to not log filename, line number, and
7886 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7888 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7889 converted to long ones. Backslashes are converted to forward
7890 slashes. Case is converted to lower. Parts of URLs that do not
7891 correspond to files are left completely alone. [Ben Laurie]
7893 *) PORT: 2 new OSs added to the list of ports:
7894 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7895 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7897 *) Add the server version (SERVER_VERSION macro) to the "server
7898 configured and running" entry in the error_log. Also build an
7899 object file at link-time that contains the current time
7900 (SERVER_BUILT global const char[]), and include that in the
7903 *) Set r->headers_out when sending responses from the proxy.
7904 This fixes things such as the logging of headers sent from
7905 the proxy. [Marc Slemko] PR#659
7907 *) support/httpd_monitor is no longer distributed because the
7908 scoreboard should not be file based if at all possible. Use
7909 mod_status to see current server snapshot.
7911 *) (set_file_slot): New function, allowing auth directives to be
7912 independent of the server root, so the server documents can be
7913 moved to a different directory or machine more easily.
7914 [David J. MacKenzie]
7916 *) If no TransferLog is given explicitly, decline
7917 to log. This supports coexistence with other logging modules,
7918 such as the custom one that UUNET uses. [David J. MacKenzie]
7920 *) Check for titles in server-parsed HTML files.
7921 Ignore leading newlines and returns in titles. The old behavior
7922 of replacing a newline after <title> with a space causes the
7923 title to be misaligned in the listing. [David J. MacKenzie]
7925 *) Change mod_cern_meta to be configurable on a per-directory basis.
7926 [David J. MacKenzie]
7928 *) Add 'Include' directive to allow inclusion of configuration
7929 files within configuration files. [Randy Terbush]
7931 *) Proxy errors on connect() are logged to the error_log (nothing
7932 new); now they include the IP address and port that failed
7933 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7935 *) Various architectures now define USE_MMAP_FILES which causes
7936 the server to use mmap() for static files. There are two
7937 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7938 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7939 number of bytes written in one cycle from a single mmap()d object,
7940 default 32768). [Dean Gaudet]
7942 *) API: Added post_read_request API phase which is run right after reading
7943 the request from a client, or right after an internal redirect. It is
7944 useful for modules setting environment variables that depend only on
7945 the headers/contents of the request. It does not run during subrequests
7946 because subrequests inherit pretty much everything from the main
7947 request. [Dean Gaudet]
7949 *) Added mod_unique_id which is used to generate a unique identifier for
7950 each hit, available in the environment variable UNIQUE_ID.
7953 *) init_modules is now called after the error logs have been opened. This
7954 allows modules to emit information messages into the error logs.
7957 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7958 information for case where proxy module is not available. [Marc Slemko]
7960 *) PORT: Apache has need for mutexes to serialize its children around
7961 accept. In prior versions either fcntl file locking or flock file
7962 locking were used. The method is chosen by the definition of
7963 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7964 and FLOCK for flock(). New options have been added:
7965 - SYSVSEM to use System V style semaphores
7966 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7967 - USLOCK to use IRIX uslock
7968 Based on timing various techniques, the following changes were made
7970 - Linux 2.x uses flock instead of fcntl
7971 - Solaris 2.x uses pthreads
7972 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7973 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7974 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7975 Martijn Koster <m.koster@pobox.com>]
7977 *) PORT: The semantics of accept/select make it very desirable to use
7978 mutexes to serialize accept when multiple Listens are in use. But
7979 in the case where only a single socket is open it is sometimes
7980 redundant to serialize accept(). Not all unixes do a good job with
7981 potentially dozens of children blocked on accept() on the same
7982 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7983 the server will avoid serialization when listening on only one socket,
7984 and use serialization when listening on multiple sockets.
7985 [Dean Gaudet] PR#467
7987 *) Configure changes: TestLib replaced by TestCompile, which has
7988 some additional capability (such as doing a sanity check of
7989 the compiler and flags selected); the version of Solaris is now
7990 available via the #define value of SOLARIS2; IRIX n32bit libs
7991 now supported and selectable by new Configuration Rule: IRIXN32;
7992 We no longer default to -O2 optimization. [Jim Jagielski]
7994 *) Updated Configure: Configuration now uses AddModule to specify
7995 module source or binary file location, relative to src directory.
7996 Modules can be dropped into modules/extra, or in their own
7997 directory, and modules can come with a Makefile or Configure can
7998 create one. Modules can add compiler or library information to
7999 generated Makefiles. [Paul Sutton]
8001 *) Source core re-organisation: distributed modules are now in
8002 modules/standard. All other source code is in main. OS-specific
8003 code is in os/{unix,emx,win32} directories. [Paul Sutton]
8005 *) mod_browser has been removed, since it's replaced by mod_setenvif.
8008 *) Fix another long-standing bug in sub_req_lookup_file where it would
8009 happily skip past access checks on subdirectories looked up with
8010 relative paths. (It's used by mod_dir, mod_negotiation,
8011 and mod_include.) [Dean Gaudet]
8013 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
8014 N is the number of <Directory> sections, and M is the number of
8015 components in the filename of an object.
8017 To achieve this optimization the following config changes were made:
8018 - Wildcards (* and ?, not the regex forms) in <Directory>s,
8019 <Files>s, and <Location>s now treat a slash as a special
8020 character. For example "/home/*/public_html" previously would
8021 match "/home/a/andrew/public_html", now it only matches things
8022 like "/home/bob/public_html". This mimics /bin/sh behaviour.
8023 - It's possible now to use [] wildcarding in <Directory>, <Files>
8025 - Regex <Directory>s are applied after all non-regex <Directory>s.
8029 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
8030 and corrupted paths. [Dean Gaudet]
8032 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
8033 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
8034 be accessed now via backreferences $1..$9 in RewriteConds test-against
8035 strings in addition to RewriteRules subst string. Second the grouped
8036 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
8037 via backreferences %1..%9 both in following RewriteCond test-against
8038 strings and RewriteRules subst string. This provides maximum flexibility
8039 through the use of backreferences.
8040 Additionally the rewriting engine was cleaned up by putting common
8041 code to the new expand_backrefs_inbuffer() function.
8042 [Ralf S. Engelschall]
8044 *) When merging the main server's <Directory> and <Location> sections into
8045 a vhost, put the main server's first and the vhost's second. Otherwise
8046 the vhost can't override the main server. [Dean Gaudet] PR#717
8048 *) The <Directory> code would merge and re-merge the same section after
8049 a match was found, possibly causing problems with some modules.
8052 *) ip-based vhosts are stored and queried using a hashing function, which
8053 has been shown to improve performance on servers with many ip-vhosts.
8054 Some other changes had to be made to accommodate this:
8055 - the * address for vhosts now behaves like _default_
8056 - the matching process now is:
8057 - match an ip-vhost directly via hash (possibly matches main
8059 - if that fails, just pretend it matched the main server
8060 - if so far only the main server has been matched, perform
8061 name-based lookups (ServerName, ServerAlias, ServerPath)
8062 *only on name-based vhosts*
8063 - if they fail, look for _default_ vhosts
8064 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
8066 *) dbmmanage overhaul:
8067 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
8068 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
8069 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
8070 - provide better seed for rand
8071 - prompt for password as per getpass(3) (turn off echo, read from
8073 - use "newstyle" crypt based on $Config{osname} ($^O)
8074 - will not add a user if already in database, use new `update' command
8076 - added `check' command to check a users' password
8077 - added `import' command to convert existing password text-files or
8078 dbm files exported with `view'
8079 - more descriptive usage, general cleanup, 'use strict' clean, etc.
8082 *) Added psocket() which is a pool form of socket(), various places within
8083 the proxy weren't properly blocking alarms while registering the cleanup
8084 for its sockets. bclose() now uses pclose() and pclosesocket(). There
8085 was a bug where the client socket was being close()d twice due a still
8086 registered cleanup. [Dean Gaudet]
8088 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
8091 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
8092 [Jason Venner <jason@idiom.com>] PR#667
8094 *) Enable ``=""'' for RewriteCond directives to match against
8095 the empty string. This is the preferred way instead of ``^$''.
8096 [Ralf S. Engelschall]
8098 *) Fixed an infinite loop in mod_imap for references above the server root
8099 [Dean Gaudet] PR#748
8101 *) mod_proxy now has a ReceiveBufferSize directive, similar to
8102 SendBufferSize, so that the TCP window can be set appropriately
8103 for LFNs. [Phillip A. Prindeville]
8105 *) mod_browser has been replaced by the more general mod_setenvif
8106 (courtesy of Paul Sutton). BrowserMatch* directives are still
8107 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
8108 UnSetEnvIfZero directives. [Ken Coar]
8110 *) "HostnameLookups double" forces double-reverse DNS to succeed in
8111 order for remote_host to be set (for logging, or for the env var
8112 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
8115 *) mod_access overhaul:
8116 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
8117 and cidr syntax (i.e. 10.1.0.0/16). PR#762
8118 - Critical path was sped up by pre-computing a few things at config time.
8119 - The undocumented syntax "allow user-agents" was removed,
8120 the replacement is "allow from env=foobar" combined with mod_browser.
8121 - When used with hostnames it now forces a double-reverse lookup
8122 no matter what the directory settings are. This double-reverse
8123 doesn't affect any of the other routines that use the remote
8124 hostname. In particular it's still passed to CGIs and the log
8125 without the double-reverse check. Related PR#860.
8128 *) When a large bwrite() occurs (larger than the internal buffer size),
8129 while there is already something in the buffer, apache will combine
8130 the large write and the buffer into a single writev(). (This is
8131 in anticipation of using mmap() for reading files.)
8134 *) In obscure cases where a partial socket write occurred while chunking,
8135 Apache would omit the chunk header/footer on the next block. Cleaned
8136 up other bugs/inconsistencies in error conditions in buff.c. Fixed
8137 a bug where a long pause in DNS lookups could cause the last packet
8138 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
8140 *) API: Added child_exit function to module structure. This is called
8141 once per "heavy-weight process" just before a server child exit()'s
8142 e.g. when max_requests_per_child is reached, etc.
8143 [Doug MacEachern, Dean Gaudet]
8145 *) mod_include cleanup showed that handle_else was being used to handle
8146 endif. It didn't cause problems, but it was cleaned up too.
8149 *) mod_cern_meta would attempt to find meta files for the directory itself
8150 in some cases, but not in others. It now avoids it in all cases.
8153 *) mod_mime_magic would core dump if there was a decompression error.
8154 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
8156 *) PORT: some variants of DGUX require -lsocket -lnsl
8157 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
8159 *) mod_autoindex now allows sorting of FancyIndexed directory listings
8160 by the various fields (name, size, et cetera), either in ascending
8161 or descending order. Just click on the column header. [Ken Coar]
8163 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
8164 CPUs like the Alpha. Apache still stores ints in pointers, but that's
8165 the relatively safe direction. [Dean Gaudet] PR#344
8167 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
8168 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
8170 *) child_main avoids an unneeded call to select() when there is only one
8171 listening socket. [Dean Gaudet]
8173 *) In the event that the server is starved for idle servers it will
8174 spawn 1, then 2, then 4, ..., then 32 servers each second,
8175 doubling each second. It'll also give a warning in the errorlog
8176 since the most common reason for this is a poor StartServers
8177 setting. The define MAX_SPAWN_RATE can be used to raise/lower
8178 the maximum. [Dean Gaudet]
8180 *) Apache now provides an effectively unbuffered connection for
8181 CGI scripts. This means that data will be sent to the client
8182 as soon as the CGI pauses or stops output; previously, Apache would
8183 buffer the output up to a fixed buffer size before sending, which
8184 could result in the user viewing an empty page until the CGI finished
8185 or output a complete buffer. It is no longer necessary to use an
8186 "nph-" CGI to get unbuffered output. Given that most CGIs are written
8187 in a language that by default does buffering (e.g. perl) this
8188 shouldn't have a detrimental effect on performance.
8190 "nph-" CGIs, which formerly provided a direct socket to the client
8191 without any server post-processing, were not fully compatible with
8192 HTTP/1.1 or SSL support. As such they would have had to implement
8193 the transport details, such as encryption or chunking, in order
8194 to work properly in certain situations. Now, the only difference
8195 between nph and non-nph scripts is "non-parsed headers".
8196 [Dean Gaudet, Sameer Parekh, Roy Fielding]
8198 *) If a BUFF is switched from buffered to unbuffered reading the first
8199 bread() will return whatever remained in the buffer prior to the
8200 switch. [Dean Gaudet]
8202 Changes with Apache 1.3a1
8204 *) Added another Configure helper script: TestLib. It determines
8205 if a specified library exists. [Jim Jagielski]
8207 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8208 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8211 *) PORT: Some architectures use size_t for various lengths in network
8212 functions such as accept(), and getsockname(). The definition
8213 NET_SIZE_T is used to control this. [Dean Gaudet]
8215 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8216 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8217 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8219 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8220 [Igor N Kovalenko <infoh@mail.wplus.net>]
8222 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8223 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8224 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8225 [Dean Gaudet] related PR#875
8227 *) API: Correct child_init() slot declaration from int to void, to
8228 match the init() declaration. Update mod_example to use the new
8231 *) added transport handle slot (t_handle) to the BUFF structure
8234 *) get_client_block() returns wrong length if policy is
8235 REQUEST_CHUNKED_DECHUNK.
8236 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
8238 *) Support the image map format of FrontPage. For example:
8239 rect /url.hrm 10 20 30 40
8240 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
8242 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
8243 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
8245 *) AddModuleInfo directive for mod_info which allows you to annotate
8246 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8248 *) Added NoProxy directive to avoid using ProxyRemote for selected
8249 addresses. Added ProxyDomain directive to cause unqualified
8250 names to be qualified by redirection.
8251 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8253 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8254 header to the remote host in the proxy. [Sameer Parekh and
8257 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8258 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8259 URLs, fixed rewritelog(), fixed forced response code handling on
8260 redirects from within .htaccess files, disabled pipe locking under
8261 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8262 no substitution, bugfixed situations where HostnameLookups is off, made
8263 mod_rewrite more thread-safe for NT port and fixed problem when creating
8264 an empty query string via "xxx?".
8265 This update also removes the copyright of Ralf S. Engelschall,
8266 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8267 exclusively copyrighted by the Apache Group now. This happened because
8268 the author now has gifted mod_rewrite exclusively to the Apache Group and
8269 no longer maintains an external version.
8270 [Ralf S. Engelschall]
8272 *) API: Added child_init function to module structure. This is called
8273 once per "heavy-weight process" before any requests are handled.
8274 See http_config.h for more details. [Dean Gaudet]
8276 *) Anonymous_LogEmail was logging on each subrequest.
8277 [Dean Gaudet] PR#421, 868
8279 *) API: Added is_initial_req() which tests if the request being
8280 processed is the initial request, or a subrequest.
8283 *) Extended SSI (mod_include) now handles additional relops for
8284 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8286 *) Configure fixed to correctly propagate user-selected options and
8287 settings (such as CC and OPTIM) to Makefiles other than
8288 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8290 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8291 directory indices to start with the contents of the HeaderName file
8292 if there is one. If there isn't one, the behaviour is unchanged.
8293 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8295 *) WIN32: Modules can now be dynamically loaded DLLs using the
8296 LoadModule/LoadFile directives. Note that module DLLs must be
8297 compiled with the multithreaded DLL version of the runtime library.
8298 [Alexei Kosut and Ben Laurie]
8300 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8301 This allows the admin to completely remove automatic indexing
8302 from the server, while still supporting the basic functions of
8303 trailing-slash redirects and DirectoryIndex files. Note that if
8304 you're carrying over an old Configuration file and you use directory
8305 indexing then you'll want to add:
8307 Module autoindex_module mod_autoindex.o
8309 before mod_dir in your Configuration. [Dean Gaudet]
8311 *) popendir/pclosedir created to properly protect directory scanning.
8312 [Dean Gaudet] PR#525
8314 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8315 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8316 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8319 *) The AccessFileName directive can now take more than one filename.
8320 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8322 *) The new mod_mime_magic can be used to "magically" determine the type
8323 of a file if the extension is unknown. Based on the unix file(1)
8324 command. [Ian Kluft <ikluft@cisco.com>]
8326 *) We now determine and display the time spent processing a
8327 request if desired. [Jim Jagielski]
8329 *) mod_status: PID field of "dead" child slots no longer displays
8330 main httpd process's PID. [Jim Jagielski]
8332 *) Makefile.nt added - to build all the bits from the command line:
8333 nmake -f Makefile.nt
8334 Doesn't yet work properly. [Ben Laurie]
8336 *) Default text of 404 error is now "Not Found" rather than the
8337 potentially misleading "File Not Found". [Ken Coar]
8339 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8340 for the net if we require people that actually need this data to
8341 enable it. [Linus Torvalds]
8343 *) directory_walk() is an expensive function, keep a little more state to
8344 avoid needless string counting. Add two new functions make_dirstr_parent
8345 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8346 The new functions are a little less general than make_dirstr, but
8347 work more efficiently (less memory, less string counting).
8350 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8351 to LDFLAGS) to avoid complications with lex rules in make files.
8352 [Dean Gaudet] PR#372
8354 *) run_method optimized to avoid needless scanning over NULLs in the
8355 module list. [Dean Gaudet]
8357 *) Revamp of (unix) scoreboard management code such that it avoids
8358 unnecessary traversals of the scoreboard on each hit. This is
8359 particularly important for high volume sites with a large
8360 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8361 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8362 httpd.h. [Dean Gaudet]
8364 *) In configurations using multiple Listen statements it was possible for
8365 busy sockets to starve other sockets of service. [Dean Gaudet]
8367 *) Added hook so standalone_main can be replaced at compile time
8368 (define STANDALONE_MAIN)
8371 *) Lowest-level read/write functions in buff.c will be replaced with
8372 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8373 compile time. The default sfio discipline will behave as apache
8374 would without sfio compiled in.
8377 *) Enhance UserDir directive (mod_userdir) to accept a list of
8378 usernames for the 'disable' keyword, and add 'enable user...' to
8379 selectively *en*able userdirs if they're globally disabled.
8382 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8383 will work with Netscape dbm files. (dbmmanage will probably not
8384 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8386 *) Add a ListenBacklog directive to control the backlog parameter
8387 passed to listen(). Also change the default to 511 from 512.
8390 *) API: A new handler response DONE which informs apache that the
8391 request has been handled and it can finish off quickly, similar to
8392 how it handles errors. [Rob Hartill]
8394 *) Turn off chunked encoding after sending terminating chunk/footer
8395 so that we can't do it twice by accident. [Roy Fielding]
8397 *) mod_expire also issues Cache-Control: max-age headers.
8400 *) API: Added kill_only_once option for free_proc_chain so that it won't
8401 aggressively try to kill off specific children. For fastcgi.
8402 [Stanley Gambarin <gambarin@OpenMarket.com>]
8404 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8406 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8407 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8408 attributes in the FancyIndexing IMG tags. [Ken Coar]
8410 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8412 *) PORT: Added Windows NT support
8413 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8415 Changes with Apache 1.2.6
8417 *) mod_include when using XBitHack Full would send ETags in addition to
8418 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8419 [Dean Gaudet] PR#1133
8421 *) SECURITY: When a client connects to a particular port/addr, and
8422 gives a Host: header ensure that the virtual host requested can
8423 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8425 *) Support virtual hosts with wildcard port and/or multiple ports
8426 properly. [Ed Korthof <ed@organic.com>]
8428 *) Fixed some case-sensitivity issues according to RFC2068.
8431 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8432 and mod_include.c. [Dean Gaudet]
8434 *) Variable 'cwd' was being used pointlessly before being set.
8437 *) SIGURG doesn't exist on all platforms.
8438 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8440 *) When an error occurs during a POST, or other operation with a
8441 request body, the body has to be read from the net before allowing
8442 a keepalive session to continue. [Roy Fielding] PR#1399
8444 *) When an error occurs in fcntl() locking suggest the user look up
8445 the docs for LockFile. [Dean Gaudet]
8447 *) table_set() and table_unset() did not deal correctly with
8448 multiple occurrences of the same key. [Stephen Scheck
8449 <sscheck@infonex.net>, Ben Laurie] PR#1604
8451 *) send_fd_length() did not calculate total_bytes_sent properly in error
8452 cases. [Ben Reser <breser@regnow.com>] PR#1366
8454 *) r->connection->user was allocated in the wrong pool causing corruption
8455 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8457 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8458 Also removed the auto-generated link to www.apache.org that was the
8459 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8461 *) Multiple "close" tokens may have been set in the "Connection"
8462 header, not an error, but a waste.
8463 [Ronald.Tschalaer@psi.ch] PR#1683
8465 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8466 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8468 *) It appears the "257th byte" bug (see
8469 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8470 at the 256th byte as well. Fixed. [Dean Gaudet]
8472 *) mod_rewrite would not handle %3f properly in some situations.
8475 *) Apache could generate improperly chunked HTTP/1.1 responses when
8476 the bputc() or rputc() functions were used by modules (such as
8477 mod_include). [Dean Gaudet]
8479 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8480 some ports. [Ralf Engelschall]
8482 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8484 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8486 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8488 Changes with Apache 1.2.5
8490 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8491 only an issue on systems without a MAXDNAME define or where
8492 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8494 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8497 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8498 directory listings. [Marc Slemko]
8500 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8503 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8504 is used to read various types of files such as htaccess and
8505 htpasswd files. [Marc Slemko]
8507 *) SECURITY: Ensure that the buffer returned by ht_time is always
8508 properly null terminated. [Marc Slemko]
8510 *) SECURITY: General mod_include cleanup, including fixing several
8511 possible buffer overflows and a possible infinite loop. This cleanup
8512 was done against 1.3 code and then backported to 1.2, the result
8513 is a large difference (due to indentation cleanup in 1.3 code).
8514 Users interested in seeing a smaller set of relevant differences
8515 should consider comparing against src/modules/standard/mod_include.c
8516 from the 1.3b3 release. Non-indentation changes to mod_include
8517 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8519 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8520 including fixing a possible buffer overflow. This cleanup also
8521 was done with 1.3 code as a basis, see the the previous note
8522 about mod_include. [Dean Gaudet]
8524 *) SECURITY: If a htaccess file can not be read due to bad
8525 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8526 The previous behavior was to ignore the htaccess file if it could not
8527 be read. This change may make some setups with unreadable
8528 htaccess files stop working. PR#817 [Marc Slemko]
8530 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8531 Make it O(n). This inefficiency could be used to mount a denial
8532 of service attack against the Apache server. Thanks to
8533 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting

8544 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8545 r->filename. Since those two are meant to be in sync with each other
8546 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
8548 *) mod_include did not properly handle all possible redirects from sub-

8558 Changes with Apache 1.2.4
8560 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8561 always making requests with the full-URI instead of just the URI path.
8562 [Marc Slemko, Roy Fielding]
8564 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8565 on this platform. [Marc Slemko]
8567 Changes with Apache 1.2.3
8569 *) The request to a remote proxy was mangled if it was generated as the
8570 result of a ProxyPass directive. URL schemes other than http:// were not
8571 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
8572 PR#812 [Lars Eilebrecht]
8574 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8575 information for case where proxy module is not available. [Marc Slemko]
8577 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8578 do for errors and cached responses. [Roy Fielding]
8580 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8582 Changes with Apache 1.2.2 [not released]
8584 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8585 happily skip past access checks on subdirectories looked up with relative
8586 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8589 *) Add lockfile name to error message printed out when
8590 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8593 *) Enhanced the chunking and error handling inside the buffer functions.
8594 [Dean Gaudet, Roy Fielding]
8596 *) When merging the main server's <Directory> and <Location> sections into
8597 a vhost, put the main server's first and the vhost's second. Otherwise
8598 the vhost can't override the main server. [Dean Gaudet] PR#717
8600 *) The <Directory> code would merge and re-merge the same section after
8601 a match was found, possibly causing problems with some modules.
8604 *) Fixed an infinite loop in mod_imap for references above the server root.
8605 [Dean Gaudet] PR#748
8607 *) mod_include cleanup showed that handle_else was being used to handle
8608 endif. It didn't cause problems, but it was cleaned up too.
8611 *) Last official synchronization of mod_rewrite with author version (because
8612 mod_rewrite is now directly developed by the author at the Apache Group):
8613 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8614 minus WIN32/NT stuff, but plus copyright removement.
8616 - workaround for detecting infinite rewriting loops
8617 - fixed setting of env vars when "-" is used as subst string
8618 - fixed forced response code on redirects (PR#777)
8619 - fixed cases where r->args is ""
8620 - kludge to disable locking on pipes under braindead SunOS
8621 - fix for rewritelog in cases where remote hostname is unknown
8622 - fixed totally damaged request_rec walk-back loop
8623 o remove static from local data and add static to global ones.
8624 o replaced ugly proxy finding stuff by simple
8625 find_linked_module("mod_proxy") call.
8626 o added missing negation char on rewritelog()
8627 o fixed a few comment typos
8628 [Ralf S. Engelschall]
8630 *) Anonymous_LogEmail was logging on each subrequest.
8631 [Dean Gaudet] PR#421, PR#868
8633 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8634 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8635 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8636 Additionally mod_browser now triggers during translate_name to workaround
8637 a deficiency in the header_parse phase.

8654 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
8655 under Solaris 2.x (up through 2.5.1). It has been fixed.
8656 [Dean Gaudet] PR#832
8658 *) API: In HTTP/1.1, whether or not a request message contains a body
8659 is independent of the request method and based solely on the presence
8660 of a Content-Length or Transfer-Encoding. Therefore, our default
8661 handlers need to be prepared to read a body even if they don't know
8662 what to do with it; otherwise, the body would be mistaken for the
8663 next request on a persistent connection. discard_request_body()
8664 has been added to take care of that. [Roy Fielding] PR#378
8666 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
8667 release version number, such that it always increases along the
8668 same lines as our source code branching. [Roy Fielding]
8670 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
8672 Changes with Apache 1.2.1
8674 *) SECURITY: Don't serve file system objects unless they are plain files,
8675 symlinks, or directories. This prevents local users from using pipes
8676 or named sockets to invoke programs for an extremely crude form of

8680 could contain "../" allowing a local user to "publish" any file on
8681 the system. No slashes are allowed now. [Dean Gaudet]
8683 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8684 (headers, readmes, titles), mod_negotiation (type maps), or
8685 mod_cern_meta (meta files). [Dean Gaudet]
8687 *) SECURITY: Apache will refuse to run as "User root" unless
8688 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8690 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8691 if it contained a .htaccess disallowing symlinks. This is contrary
8692 to the rule that symlink permissions are tested with the symlink
8693 options of the parent directory. [Dean Gaudet] PR#353
8695 *) CONFIG: The LockFile directive can be used to place the serializing
8696 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8697 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8700 *) Request processing now retains state of whether or not the request
8701 body has been read, so that internal redirects and subrequests will
8702 not try to read it twice (and block). [Roy Fielding]
8704 *) Add a placeholder in modules/Makefile to avoid errors with certain
8705 makes. [Marc Slemko]
8707 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

8713 *) Attempt to work around problems with third party libraries that do not
8714 handle high numbered descriptors (examples include bind, and
8715 solaris libc). On all systems apache attempts to keep all permanent
8716 descriptors above 15 (called the low slack line). Solaris users
8717 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8718 which keeps all non-FILE * descriptors above 255. On all systems
8719 this should make supporting large numbers of vhosts with many open
8720 log files more feasible. If this causes trouble please report it,
8721 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8722 [Dean Gaudet] various PRs
8724 *) Related to the last entry, network sockets are now opened before
8725 log files are opened. The only known case where this can cause
8726 problems is under Solaris with many virtualhosts and many Listen
8727 directives. But using -DHIGH_SLACK_LINE=256 described above will
8728 work around this problem. [Dean Gaudet]
8730 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and

8783 reading from one buffer and writing to another, at least until it has
8784 a custom timeout handler. [Roy Fielding and Petr Lampa]

8794 *) Virtual hosts with the same ServerName, but on different ports, were
8795 not being selected properly. [Ed Korthof]

8800 [Chuck Murcko] PR#614
8802 *) If multiple requests on a single connection are used to retrieve

8819 *) If a soft_timeout occurs after keepalive is set, then the main child
8820 loop would try to read another request even though the connection
8821 has been aborted. [Roy Fielding]
8823 *) Configure changes: Allow for whitespace at the start of a
8824 Module declaration. Also, be more understanding about the
8825 CC=/OPTIM= format in Configuration. Finally, fix compiler
8826 flags if using HP-UX's cc compiler. [Jim Jagielski]
8828 *) Subrequests and internal redirects now inherit the_request from the
8829 original request-line. [Roy Fielding]
8831 *) Test for error conditions before creating output header fields, since
8832 we don't want the error message to include those fields. Likewise,
8833 reset the content_language(s) and content_encoding of the response
8834 before generating or redirecting to an error message, since the new
8835 message will have its own Content-* definitions. [Dean Gaudet]

8838 and 304 responses) and err_headers_out (headers sent with all responses).
8839 Avoid the overhead of copying tables if err_headers_out is empty
8840 (the usual case). [Roy Fielding]

8843 not properly checking both the value configured by the DefaultType
8844 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8845 of DEFAULT_TYPE to match the documented default (text/plain).

8851 *) Properly initialize the flock structures used by the mutex locking
8852 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8855 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8856 (and NCSA httpd) definition wherein it was the extra path info beyond
8857 the CGI script filename. The environment variable FILEPATH_INFO has
8858 been removed, and instead we supply the original REQUEST_URI to any
8859 script that wants to be Apache-specific and needs the real URI path.
8860 This solves a problem with existing scripts that use extra path info
8861 in the ScriptAlias directive to pass options to the CGI script.
8864 *) The _default_ change in 1.2b10 will change the behaviour on configs
8865 that use multiple Listen statements for listening on multiple ports.
8866 But that change is necessary to make _default_ consistent with other
8867 forms of <VirtualHost>. It requires such configs to be modified
8868 to use <VirtualHost _default_:*>. The documentation has been
8869 updated. [Dean Gaudet] PR#530
8871 *) If an ErrorDocument CGI script is used to respond to an error
8872 generated by another CGI script which has already read the message
8873 body of the request, the server would block trying to read the
8874 message body again. [Rob Hartill]

8895 Changes with Apache 1.2b9 [never announced]
8897 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8898 changes and in anticipation of 1.2 final release. [Roy Fielding]
8900 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8901 the connection (e.g., when user presses Stop). Apache will now stop
8902 trying to send a message body immediately after an error from write.
8903 [Roy Fielding and Nathan Kurz] PR#335
8905 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8906 than mod_alias, and mod_alias has higher priority than mod_proxy;

8912 conditions in both forms of restart, and in SIGTERM. See
8913 htdocs/manual/stopping.html for details on stopping and
8914 restarting the parent. [Dean Gaudet]
8916 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8917 memory allocator to avoid a behaviour that required extra blocks to
8918 be allocated. [Dean Gaudet]
8920 *) Allow suexec to access files relative to current directory but not

8948 *) If a soft timeout (or lingerout) occurs while trying to flush a
8949 buffer or write inside buff.c or fread'ing from a CGI's output,
8950 then the timeout would be ignored. [Roy Fielding] PR#373
8952 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8953 parsing of headers. If the terminating empty-line CRLF occurs starting
8954 at the 256th or 257th byte of output, then Navigator will think a normal
8955 image is invalid. We are guessing that this is because their initial
8956 read of a new request uses a 256 byte buffer. We check the bytes written
8957 so far and, if we are about to tickle the bug, we instead insert a
8958 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

8961 of an external redirection. [Roy Fielding and Paul Sutton]

9050 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
9052 *) Report extra info from errno with many errors that cause httpd to exit.
9053 spawn_child, popenf, and pclosef now have valid errno returns in the
9054 event of an error. Correct problems where errno was stomped on
9055 before being reported. [Dean Gaudet]
9057 *) In the proxy, if the cache filesystem was full, garbage_coll() was
9058 never called, and thus the filesystem would remain full indefinitely.
9059 We now also remove incomplete cache files left if the origin server
9060 didn't send a Content-Length header and either the client has aborted
9061 transfer or bwrite() to client has failed. [Petr Lampa]
9063 *) Fixed the handling of module and script-added header fields.
9064 Improved the interface for sending header fields and reduced
9065 the duplication of code between sending okay responses and errors.
9066 We now always send both headers_out and err_headers_out, and
9067 ensure that the server-reserved fields are not being overridden,
9068 while not overriding those that are not reserved. [Roy Fielding]
9070 *) Moved transparent content negotiation fields to err_headers_out
9071 to reflect above changes. [Petr Lampa]
9073 *) Fixed the determination of whether or not we should make the
9074 connection persistent for all of the cases where some other part
9075 of the server has already indicated that we should not. Also
9076 improved the ordering of the test so that chunked encoding will
9077 be set whenever it is desired instead of only when KeepAlive
9078 is enabled. Added persistent connection capability for most error
9079 responses (those that do not indicate a bad input stream) when
9080 accessed by an HTTP/1.1 client. [Roy Fielding]
9082 *) Added missing timeouts for sending header fields, error responses,
9083 and the last chunk of chunked encoding, each of which could have
9084 resulted in a process being stuck in write forever. Using soft_timeout
9085 requires that the sender check for an aborted connection rather than
9086 continuing after an EINTR. Timeouts that used to be initiated before
9087 send_http_header (and never killed) are now initiated only within or
9088 around the routines that actually do the sending, and not allowed to
9089 propagate above the caller. [Roy Fielding]
9091 *) mod_auth_anon required an @ or a . in the email address, not both.
9094 *) per_dir_defaults weren't set correctly until directory_walk for
9095 name-based vhosts. This fixes an obscure bug with the wrong config
9096 info being used for vhosts that share the same ip as the server.
9099 *) Improved generation of modules/Makefile to be more generic for
9100 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
9102 *) Generate makefile dependency for Configuration based on the actual
9103 name given when running the Configure process. [Dean Gaudet]
9105 *) Fixed problem with vhost error log not being set prior to
9106 initializing virtual hosts. [Dean Gaudet]
9108 *) Fixed infinite loop when a trailing slash is included after a type map
9109 file URL (extra path info). [Petr Lampa]
9111 *) Fixed server status updating of per-connection counters. [Roy Fielding]
9113 *) Add documentation for DNS issues (reliability and security), and try
9114 to explain the virtual host matching process. [Dean Gaudet]
9116 *) Try to continue gracefully by disabling the vhost if a DNS lookup
9117 fails while parsing the configuration file. [Dean Gaudet]
9119 *) Improved calls to setsockopt. [Roy Fielding]
9121 *) Negotiation changes: Don't output empty content-type in variant list;
9122 Output charset in variant list; Return sooner from handle_multi() if
9123 no variants found; Add handling of '*' wildcard in Accept-Charset.
9124 [Petr Lampa and Paul Sutton]
9126 *) Fixed overlaying of request/sub-request notes and headers in
9127 mod_negotiation. [Dean Gaudet]
9129 *) If two variants' charset quality are equal and one is the default
9130 charset (iso-8859-1), then prefer the variant that was specifically
9131 listed in Accept-Charset instead of the default. [Petr Lampa]
9133 *) Memory allocation problem in push_array() -- it would corrupt memory
9134 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
9136 *) invoke_handler() doesn't handle mime arguments in content-type
9139 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
9142 *) Fixed problem with ErrorDocument not working for virtual hosts
9143 due to one of the performance changes in 1.2b7. [Dean Gaudet]
9145 *) Log an error message if we get a request header that is too long,
9146 since it may indicate a buffer overflow attack. [Marc Slemko]
9148 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
9149 not reject URLs without a double-slash, as per RFC2068 section 3.2.
9150 [Ken Coar] PR #146, #187
9152 *) Added table entry placeholder for new header_parser callback
9153 in all of the distributed modules. [Ken Coar] PR #191
9155 *) Allow for cgi files without the .EXE extension on them under OS/2.
9156 [Garey Smiley] PR #59
9158 *) Fixed error message when resource is not found and URL contains
9159 path info. [Petr Lampa and Dean Gaudet] PR #40
9161 *) Fixed user and server confusion over what should be a virtual host
9162 and what is the main server, resulting in access to something
9163 other than the name defined in the virtualhost directive (but
9164 with the same IP address) failing. [Dean Gaudet]
9166 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
9167 AIX; improves the redirection stuff to enable the users to generally
9168 redirect to http, https, gopher and ftp; added TIME variable for
9169 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
9170 special patterns >STRING, <STRING and =STRING to RewriteCond, which
9171 can be used in conjunction with %{TIME} or other variables to create
9172 time-dependent rewriting rules. [Ralf S. Engelschall]
9174 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
9175 Module authors may need to adjust their code for proper cleanup to take
9176 place (that is, call note_cleanups_for_fd()). This change fixes problems
9177 with file descriptors being erroneously closed when the proxy module was
9178 in use. [Ben Laurie]
9180 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
9181 initgroups() to hose the group information needed for later
9182 comparisons. [Randy Terbush]
9184 *) Remove unnecessary call to va_end() in create_argv() which
9185 caused a SEGV on some systems.
9187 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
9190 *) Clear memory allocated for listeners. [Randy Terbush]
9192 *) Improved handling of IP address as a virtualhost address and
9193 introduced "_default_" as a synonym for the default vhost config.
9194 [Dean Gaudet] PR #212
9196 Changes with Apache 1.2b7
9198 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
9200 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
9202 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
9203 - replace protocol response numbers with symbols
9204 - save variant-list into main request notes
9205 - free allocated memory from subrequests
9206 - merge notes, headers_out and err_headers_out
9208 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
9209 "HTTP/#.# ###*" to be more lenient about what we accept.
9212 *) more proxy FTP bug fixes:
9213 - Changed send_dir() to remove user/passwd from displayed URL.
9214 - Changed login error messages to be more descriptive.
9215 - remove setting of SO_DEBUG socket option
9216 - Make ftp_getrc() more lenient about multiline responses,
9217 specifically, 230 responses which don't have continuation 230-
9218 on each line). These seem to be all NT FTP servers, and while
9219 perhaps questionable, they appear to be legal by RFC 959.
9220 - Add missing kill_timeout() after transfer to user completes.
9223 *) Fixed problem where a busy server could hang when restarting
9224 after being sent a SIGHUP due to child processes not exiting.
9227 *) Modify mod_include escaping so a '\' only signifies an escaped
9228 character if the next character is one that needs
9229 escaping. [Ben Laurie]
9231 *) Eliminated possible infinite loop in mod_imap when relative URLs are
9232 used with a 'base' directive that does not have a '/' in it.
9233 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
9235 *) Reduced the default timeout from 1200 seconds to 300, and the
9236 one in the sample configfile from 400 to 300. [Marc Slemko]
9238 *) Stop vbprintf from crashing if given a NULL string pointer;
9239 print (null) instead. [Ken Coar]
9241 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
9242 [Marc Slemko and Roy Fielding]
9244 *) Fixed problem with mod_cgi-generated internal redirects trying to
9245 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9247 *) Reduced timeout on lingering close, removed possibility of a blocked
9248 read causing the child to hang, and stopped logging of errors if
9249 the socket is not connected (reset by client). [Roy Fielding]
9251 *) Rearranged main child loop to remove duplication of code in
9252 select/accept and keep-alive requests, fixed several bugs regarding
9253 checking scoreboard_image for exit indication and failure to
9254 account for all success conditions and trap all error conditions,
9255 prevented multiple flushes before closing the socket; close the entire
9256 socket buffer instead of just one descriptor, prevent logging of
9257 EPROTO and ECONNABORTED on platforms where supported, and generally
9258 improved readability. [Roy Fielding]
9260 *) Extensive performance improvements. Cleaned up inefficient use of
9261 auto initializers, multiple is_matchexp calls on a static string,
9262 and excessive merging of response_code_strings. [Dean Gaudet]
9264 *) Added double-buffering to mod_include to improve performance on
9265 server-side includes. [Marc Slemko]
9267 *) Several fixes for suexec wrapper. [Randy Terbush]
9268 - Make wrapper work for files on NFS filesystem.
9269 - Fix portability problem of MAXPATHLEN.
9270 - Fix array overrun problem in clean_env().
9271 - Fix allocation of PATH environment variable
9273 *) Removed extraneous blank line is description of mod_status chars.
9276 *) Logging of errors from the call_exec routine simply went nowhere,
9277 since the logfile fd has been closed, so now we send them to stderr.
9278 [Harald T. Alvestrand]
9280 *) Fixed core dump when DocumentRoot is a CGI.
9281 [Ben Laurie, reported by geddis@tesserae.com]
9283 *) Fixed potential file descriptor leak in mod_asis; updated it and
9284 http_core to use pfopen/pfclose instead of fopen/fclose.
9285 [Randy Terbush and Roy Fielding]
9287 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9288 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9289 [Dean Gaudet and Ken Coar]
9291 *) Return a 302 response code to the client when sending a redirect
9292 due to a missing trailing '/' on a directory instead of a 301; now
9293 it is cacheable. [Markus Gyger]
9295 *) Fix condition where, if a bad directive occurs in .htaccess, and
9296 sub_request() goes first to this directory, then log_reason() will
9297 SIGSEGV because it doesn't have initialized r->per_dir_config.
9298 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9300 *) Fix handling of lang_index in is_variant_better(). This was
9301 causing problems which resulted in the server sending the
9302 wrong language document in some cases. [Petr Lampa]
9304 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9305 the clean environment on some systems.
9307 *) Tweak byteserving code (e.g. serving PDF files) to work around
9308 bugs in Netscape Navigator and Microsoft Internet Explorer.
9309 Emit Content-Length header when sending multipart/byteranges.
9312 *) Port to HI-UX/WE2. [Nick Maclaren]
9314 *) Port to HP MPE operating system for HP 3000 machines
9315 [Mark Bixby <markb@cccd.edu>]
9317 *) Fixed bug which caused a segmentation fault if only one argument
9318 given to RLimit* directives. [Ed Korthof]
9320 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9322 *) Improved buffered output to the client by delaying the flush decision
9323 until the BUFF code is actually about to read the next request.
9324 This fixes a problem introduced in 1.2b5 with clients that send
9325 an extra CRLF after a POST request. Also improved chunked output
9326 performance by combining writes using writev() and removing as
9327 many bflush() calls as possible. NOTE: Platforms without writev()
9328 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9329 or Configure, unless we have already done so. [Dean Gaudet]
9331 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9333 *) Fixed mod_info output corruption bug introduced by buffer overflow
9334 fixes. [Dean Gaudet]
9336 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9337 for the special case of a 304 response. [Paul Sutton]
9339 *) Improved handling of TRACE method by bypassing normal method handling
9340 and header parsing routines; fixed Allow response to always allow TRACE.
9343 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9345 *) Cleaned-up some of the generated HTML. [Ken Coar]
9347 Changes with Apache 1.2b6
9349 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9351 *) Fix typo introduced in fix for potential infinite loop around
9352 accept() in child_main(). This change caused the rev to 1.2b6.
9353 1.2b5 was never a public beta.
9355 Changes with Apache 1.2b5
9357 *) Change KeepAlive semantics (On|Off instead of a number), add
9358 MaxKeepAliveRequests directive. [Alexei Kosut]
9360 *) Various NeXT compilation patches, as well as a change in
9361 regex/regcomp.c since that file also used a NEXT define.
9364 *) Allow * to terminate the end of a directory match in mod_dir.
9365 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9367 *) Don't call can_exec() if suexec_enabled. Calling this requires
9368 scripts executed by the suexec wrapper to be world executable, which
9369 defeats one of the advantages of running the wrapper. [Randy Terbush]
9371 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9374 *) Migration from sprintf() to snprintf() to avoid buffer
9375 overflows. [Marc Slemko]
9377 *) Provide portable snprintf() implementation (ap_snprintf)
9378 as well as *cvt family. [Jim Jagielski]
9380 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9383 *) Remove mod_fastcgi.c from the distribution. This module appears
9384 to be maintained more through the Open Market channels and should
9385 continue to be easily available at http://www.fastcgi.com/
9387 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9388 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9390 *) mod_info assumed that the config files were relative to ServerRoot.
9393 *) CGI scripts called as an error document resulting from failed
9394 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9396 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9399 *) Properly check errno to prevent display of a directory index
9400 when server receives a long enough URL to confuse stat().
9403 *) Several security enhancements to suexec wrapper. It is _highly_
9404 recommended that previously installed versions of the wrapper
9405 be replaced with this version. [Randy Terbush, Jason Dour]
9407 - ~user execution now properly restricted to ~user's home
9408 directory and below.
9409 - execution restricted to UID/GID > 100
9410 - restrict passed environment to known variables
9411 - call setgid() before initgroups() (portability fix)
9412 - remove use of setenv() (portability fix)
9414 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9416 *) Add access control via environment variables. [Ben Laurie]
9418 *) Add rflush() function. [Alexei Kosut]
9420 *) remove duplicate pcalloc() call in new_connection().
9422 *) Fix incorrect comparison which could allow number of children =
9423 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9424 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9426 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9427 AIX PS/2, CONVEXOS. [Jim Jagielski]
9429 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9430 It's more portable. [Martin Kraemer]
9432 *) Replace references to make in Makefile.tmpl with $(MAKE).
9435 *) Add ProxyBlock directive w/IP address caching. Add IP address
9436 caching to NoCache directive as well. ProxyBlock works with all
9437 handlers; NoCache now also works with FTP for anonymous logins.
9438 Still more code cleanup. [Chuck Murcko]
9440 *) Add "header parse" API hook [Ben Laurie]
9442 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9444 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9446 *) Correctly allow access and auth directives in <Files> sections in
9447 server config files. [Alexei Kosut]
9449 *) Fix bug with ServerPath that could cause certain files to be not
9450 found by the server. [Alexei Kosut]
9452 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9453 double-quote from text and so that it properly checks for unsupported
9454 status codes using the new index_of_response interface. [Roy Fielding]
9456 *) Multiple fixes to the lingering_close code in order to avoid being
9457 interrupted by a stray timeout, to avoid lingering on a connection
9458 that has already been aborted or never really existed, to ensure that
9459 we stop lingering as soon as any error condition is received, and to
9460 prevent being stuck indefinitely if the read blocks. Also improves
9461 reporting of error conditions. [Marc Slemko and Roy Fielding]
9463 *) Fixed initialization of parameter structure for sigaction.
9464 [mgyger@itr.ch, Adrian Filipi-Martin]
9466 *) Fixed reinitializing the parameters before each call to accept and
9467 select, and removed potential for infinite loop in accept.
9468 [Roy Fielding, after useful PR from adrian@virginia.edu]
9470 *) Fixed condition where, if a child fails to fork, the scoreboard would
9471 continue to say SERVER_STARTING forever. Eventually, the main process
9472 would refuse to start new children because count_idle_servers() will
9473 count those SERVER_STARTING entries and will always report that there
9474 are enough idle servers. [Phillip Vandry]
9476 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9477 Avoided calling bflush() when the client is pipelining requests.
9478 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9480 *) Added description of "." mode in server-status [Jim Jagielski]
9482 Changes with Apache 1.2b4
9484 *) Fix possible race condition in accept_mutex_init() that
9485 could leave a small security hole open allowing files to be
9486 overwritten in cases where the server UID has write permissions.
9489 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9491 *) Fix portablity problem in util_script where ARG_MAX may not be
9492 defined for some systems.
9494 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9497 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9498 style magic #! token for better script portability. [Garey Smiley]
9500 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9501 execution for ~userdir CGI. [Jason Dour]
9503 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9505 *) Fix month off by one in suexec wrapper logging.
9507 Changes with Apache 1.2b3:
9509 *) Fix error in mod_cgi which could cause resources not to be properly
9510 freed, or worse. [Dean Gaudet]
9512 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9514 *) Add set_flag_slot() at the request of Dirk and others.
9517 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9519 *) Add changes to improve the error message given for invalid
9520 ServerName parameters. [Dirk vanGulik]
9522 *) Add "Authoritative" directive for Auth modules that don't
9523 currently have it. This gives admin control to assign authoritative
9524 control to an authentication scheme and allow "fall through" for
9525 those authentication modules that aren't "Authoritative" thereby
9526 allowing multiple authentication mechanisms to be chained.
9529 *) Remove requirement for ResourceConfig/AccessConfig if not using
9530 the three config file layout. [Randy Terbush]
9532 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9534 *) Changes to suexec wrapper to fix the following problems:
9535 1. symlinked homedirs will kill ~userdirs.
9536 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9537 3. CGI command lines paramters problems
9538 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9539 [Randy Terbush, Jason Dour]
9541 *) Change create_argv() to accept variable arguments. This fixes
9542 a problem where arguments were not getting passed to the CGI via
9543 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9545 *) Collapse multiple slashes in path URLs to properly apply
9546 handlers defined by <Location>. [Alexei Kosut]
9548 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9550 *) Improve the accuracy of request duration timings by setting
9551 r->request_time in read_request_line() instead of read_request().
9554 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9555 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9557 *) Add the ability to pass different Makefile.tmpl files to Configure
9558 using the -make flag. [Rob Hartill]
9560 *) Fix coredump triggered when sending a SIGHUP to the server caused
9561 by an assertion failure, in turn caused by an uninitialised field in a
9565 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9566 PATH_INFO from previous versions of Apache (in certain situations,
9567 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9568 [later removed in 1.2b11]
9570 *) Add rwrite() function to API to allow for sending strings of
9571 arbitrary length. [Doug MacEachern]
9573 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9575 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9576 NeXT. [Jim Jagielski]
9578 *) Removed recent modification to promote the status code on internal
9579 redirects, since the correct fix was to change the default log format
9580 in mod_log_config so that it outputs the original status. [Rob Hartill]
9582 Changes with Apache 1.2b2:
9584 *) Update set_signals() to use sigaction() for setting handlers.
9585 This appears to fix a re-entrant problem in the seg_fault()
9586 bus_error() handlers. [Randy Terbush]
9588 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9590 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9592 *) proxy_http.c bugfixes: [Chuck Murcko]
9593 1) fixes possible NULL pointer reference w/NoCache
9594 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9595 host would cache nothing if it was in the local domain,
9596 and the local domain was in the NoCache list)
9597 3) Adds Host: header when not available
9598 4) Some code cleanup and clarification
9600 *) mod_include.c bugfixes:
9601 1) Fixed an ommission that caused include variables to not
9602 be parsed in config errmsg directives [Howard Fear]
9603 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9604 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9605 4) Allow backslash-escaping to all quoted text
9606 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9607 5) Pass variable to command line if not set in XSSI's env
9610 *) Fix infinite loop when processing Content-language lines in
9611 type-map files. [Alexei Kosut]
9613 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9615 *) Fixed problem in set_[user|group] that prevented CGI execution
9616 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9618 *) Added PORTING information file. [Jim Jagielski]
9620 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9622 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9624 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9625 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9627 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9628 which caused problems of systems where socket s_addr is >32bits.
9630 *) Added comment to explain (r->chunked = 1) side-effect in
9631 http_protocol.c [Roy Fielding]
9633 *) Replaced use of index() in mod_expires.c with more appropriate
9634 and portable isdigit() test. [Ben Laurie]
9636 *) Updated Configure for ...
9637 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9638 *-dg-dgux* (bad pattern match)
9639 QNX (DEF_WANTHSREGEX=yes)
9640 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9643 and added some user diagnostic info. [Ben Laurie]
9645 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9646 for better portability. [Jim Jagielski]
9648 *) Updated helpers/GuessOS for ...
9649 SCO 5 (recognize minor releases)
9650 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9651 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9652 IRIX64 (-sgi-irix64)
9653 ULTRIX (-unknown-ultrix)
9654 SINIX (-whatever-sysv4)
9655 NCR Unix (-ncr-sysv4)
9656 and fixed something in helpers/PrintPath [Ben Laurie]
9658 Changes with Apache 1.2b1
9660 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9662 Changes with Apache 1.1.1
9664 *) Fixed bug where Cookie module would make two entries in the
9665 logfile for each access [Mark Cox]
9667 *) Fixed bug where Redirect in .htaccess files would cause memory
9668 leak. [Nathan Neulinger]
9670 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9672 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9674 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9676 Changes with Apache 1.1.0
9678 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9680 *) Bring QNX support up to date. [Ben Laurie]
9682 *) Make virtual hosts default to main server keepalive parameters.
9683 [Alexei Kosut, Ben Laurie]
9685 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9687 *) Fix missing address family for connect, also remove unreachable statement
9688 in mod_proxy. [Ben Laurie]
9690 *) mod_env now turned on by default in Configuration.tmpl.
9692 *) Bugs which were fixed:
9693 a) yet more mod_proxy bugs [Ben Laurie]
9694 b) CGI works again with inetd [Alexei Kosut]
9695 c) Leading colons were stripped from passwords [osm@interguide.com]
9696 d) Another fix to multi-method Limit problem [jk@tools.de]
9698 Changes with Apache 1.1b4
9700 *) r->bytes_sent variable restored. [Robert Thau]
9702 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9704 *) More possibly unsecure programs removed from the support directory.
9706 *) More mod_auth_msql authentication improvements.
9708 *) VirtualHosts based on Host: headers no longer conflict with the
9711 *) OS/2 compatibility enhancements. [Gary Smiley]
9713 *) POST now allowed to directory index CGI scripts.
9715 *) Actions now work with files of the default type.
9717 *) Bugs which were fixed:
9718 a) more mod_proxy bugs
9719 b) early termination of inetd requests
9720 c) compile warnings on several systems
9721 d) problems when scripts stop reading output early
9723 Changes with Apache 1.1b3
9725 *) Much of cgi-bin and all of cgi-src has been removed, due to
9726 various security holes found and that we could no longer support
9729 *) The "Set-Cookie" header is now special-cased to not merge multiple
9730 instances, since certain popular browsers can not handle multiple
9731 Set-Cookie instructions in a single header. [Paul Sutton]
9733 *) rprintf() added to buffer code, occurrences of sprintf removed.
9736 *) CONNECT method for proxy module, which means tunneling SSL should work.
9737 (No crypto needed) Also a NoCache config directive.
9739 *) Several API additions: pstrndup(), table_unset() and get_token()
9740 functions now available to modules.
9742 *) mod_imap fixups, in particular Location: headers are now complete
9745 *) New "info" module which reports on installed module set through a
9746 special URL, a la mod_status.
9748 *) "ServerPath" directive added - allows for graceful transition
9749 for Host:-header-based virtual hosts.
9751 *) Anonymous authentication module improvements.
9753 *) MSQL authentication module improvements.
9755 *) Status module design improved - output now table-based. [Ben Laurie]
9757 *) htdigest utility included for use with digest authentication
9760 *) mod_negotiation: Accept values with wildcards to be treated with
9761 less priority than those without wildcards at the same quality
9762 value. [Alexei Kosut]
9764 *) Bugs which were fixed:
9765 a) numerous mod_proxy bugs
9766 b) CGI early-termination bug [Ben Laurie]
9767 c) Keepalives not working with virtual hosts
9768 d) RefererIgnore problems
9769 e) closing fd's twice in mod_include (causing core dumps on
9770 Linux and elsewhere).
9772 Changes with Apache 1.1b2
9775 a) core dumps in mod_digest
9776 b) truncated hostnames/ip address in the logs
9777 c) relative URL's in mod_imap map files
9779 Changes with Apache 1.1b1
9781 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9783 Changes with Apache 1.0.3
9785 *) Internal redirects which occur in mod_dir.c now preserve the
9786 query portion of a request (the bit after the question mark).
9789 *) Escape active characters '<', '>' and '&' in html output in
9790 directory listings, error messages and redirection links.
9793 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9795 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9798 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9800 *) Reset timeout timer after each successful fwrite() to the network.
9801 This patch adds a reset_timeout() procedure that is called by
9802 send_fd() to reset the timeout ever time data is written to the net.
9805 *) timeout() signal handler now checks for SIGPIPE and reports
9806 lost connections in a more user friendly way. [Rob Hartill]
9808 *) Location of the "scoreboard" file which used to live in /tmp is
9809 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9810 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9812 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9814 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9815 which caused a SEGV with cookies enabled
9817 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9820 *) Log the UNIX textual error returned by some system calls, in
9821 particular errors from accept() [David Robinson]
9823 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9825 Changes with Apache 1.0.2
9827 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9828 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9830 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9833 *) past changes to http_config.c to only use the
9834 setrlimit function on systems defining RLIMIT_NOFILE
9835 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9836 for SUNOS and prototypes the needed functions.
9838 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9841 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9843 *) Merge multiple headers from CGI scripts instead of taking last
9844 one. [David Robinson]
9846 *) Add support for SCO 5. [Ben Laurie]
9848 Changes with Apache 1.0.1
9850 *) Silence mod_log_referer and mod_log_agent if not configured
9853 *) Recursive includes can occur if the client supplies PATH_INFO data
9854 and the server provider uses relative links; as file.html
9855 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9857 *) The replacement for initgroups() did not call {set,end}grent(). This
9858 had two implications: if anything else used getgrent(), then
9859 initgroups() would fail, and it was consuming a file descriptor.
9862 *) On heavily loaded servers it was possible for the scoreboard to get
9863 out of sync with reality, as a result of a race condition.
9864 The observed symptoms are far more Apaches running than should
9865 be, and heavy system loads, generally followed by catastrophic
9866 system failure. [Ben Laurie]
9868 *) Fix typo in license. [David Robinson]
9870 Changes with Apache 1.0.0 23 Nov 1995
9872 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9874 Changes with Apache 0.8.16 05 Nov 1995
9876 *) New man page for 'httpd' added to support directory [David Robinson]
9878 *) .htgroup files can have more than one line giving members for a
9879 given group (each must have the group name in front), for NCSA
9880 back-compatibility [Robert Thau]
9882 *) Mutual exclusion around accept() is on by default for SVR4 systems
9883 generally, since they generally can't handle multiple processes in
9884 accept() on the same socket. This should cure flaky behavior on
9885 a lot of those systems. [David Robinson]
9887 *) AddType, AddEncoding, and AddLanguage directives take multiple
9888 extensions on a single command line [David Robinson]
9890 *) UserDir can be disabled for a given virtual host by saying
9891 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9892 that this didn't work. [David Robinson]
9894 *) Compiles on QNX [Ben Laurie]
9896 *) Corrected parsing of ctime time format [David Robinson]
9898 *) httpd does a perror() before exiting if it can't log its pid
9899 to the PidFile, to make diagnosing the error a bit easier.
9902 *) <!--#include file="..."--> can no longer include files in the
9903 parent directory, for NCSA back-compatibility. [David Robinson]
9905 *) '~' is *not* escaped in URIs generated for directory listings
9908 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9910 *) Fixed bug involving handling URIs with escaped %-characters
9911 in redirects [David Robinson]
9913 Changes with Apache 0.8.15 14 Oct 1995
9915 *) Switched to new, simpler license
9917 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9919 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9921 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9923 *) Correctly handles internal redirects to files with names containing '%'
9926 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9928 *) Use geteuid() rather than getuid() to see if we have root privilege,
9929 so that server correctly resets privilege if run setuid root. [Andrew
9932 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9935 *) Fix relative URLs in imagemap files [Randy Terbush]
9937 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9940 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9941 entries all name the same one. [David Robinson]
9943 *) Fix directory listings with filenames containing unusual characters
9946 *) Better URI-escaping for generated URIs in directories with filenames
9947 containing unusual characters [Ben Laurie]
9949 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9951 *) Unblock alarms on error return from spawn_child() [David Robinson]
9953 *) Sample Config files have extra note for SCO users [Ben Laurie]
9955 *) Configuration has note for HP-UX users [Rob Hartill]
9957 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9959 *) Nuked bogus #define in httpd.h [David Robinson]
9961 *) Better test for whether a system has setrlimit() [David Robinson]
9963 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9965 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9968 Changes with Apache 0.8.14 19 Sep 1995
9970 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9972 *) AddDescription works (better) [Ben Laurie]
9974 *) Leaves an intelligible error diagnostic when it can't set group
9975 privileges on standalone startup [Andrew Wilson]
9977 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9978 that machine, which claims to be BSD but does not support RLIMIT.
9981 *) gcc -Wall no longer complains about an unused variable when util.c
9982 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9984 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9986 Changes with Apache 0.8.13 07 Sep 1995
9988 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9990 *) Have built-in imagemap code recognize & honor Point directive [James
9993 *) Generate cleaner directory listings in directories with a mix of
9994 long and short filenames [Rob Hartill]
9996 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9998 *) Properly default ServerName for virtual servers [Robert Thau]
10000 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
10001 Paul Richards and a cast of thousands...]
10003 *) On self-identified BSD systems (we don't try to guess any more),
10004 allocate a few extra file descriptors per virtual host with setrlimit,
10005 if we can, to avoid running out. [Randy Terbush]
10007 *) Write 22-character lock file name into buffer with enough space
10008 on startup [Konstantin Olchanski]
10010 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
10013 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
10015 *) Suppress -Wall warning by initializing variable in negotiation code
10016 [Tobias Weingartner]
10018 Changes with Apache 0.8.12 31 Aug 1995
10020 *) Doesn't pause three seconds after including a CGI script which is
10021 too slow to die off (this is done by not even trying to kill off
10022 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
10023 after the entire document has been processed). [Robert Thau]
10025 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
10027 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
10029 *) Allows .htaccess files to override <Directory> sections naming the
10030 same directory [David Robinson]
10032 *) Removed an efficiency hack in sub_req_lookup_uri which was
10033 causing certain extremely marginal cases (e.g., ScriptAlias of a
10034 *particular* index.html file) to fail. [David Robinson]
10036 *) Doesn't log an error when the requested URI requires
10037 authentication, but no auth header line was supplied by the
10038 client; this is a normal condition (the client doesn't no auth is
10039 needed here yet). [Robert Thau]
10041 *) Behaves more sanely when the name server loses its mind [Sean Welch]
10043 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
10045 *) RFC931 code no longer passes out name of prior clients on current
10046 requests if the current request came from a server that doesn't
10047 do RFC931. [David Robinson]
10049 *) Configuration script accepts "Module" lines with trailing whitespace.
10052 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
10054 *) Cleaned up comments in mod_cgi.c [Robert Thau]
10056 Changes with Apache 0.8.11 24 Aug 1995
10058 *) Wildcard <Directory> specifications work. [Robert Thau]
10060 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
10062 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
10063 the file being requested itself, in addition to the directories leading
10064 up to it. [Robert Thau]
10066 *) Logs access failures due to symlink checks or invalid client address
10067 in the error log [Roy Fielding, Robert Thau]
10069 *) Symlink checks deal correctly with systems where lstat of
10070 "/path/to/some/link/" follows the link. [Thau, Fielding]
10072 *) Doesn't reset DirectoryIndex to 'index.html' when
10073 other directory options are set in a .htaccess file. [Robert Thau]
10075 *) Clarified init code and nuked bogus warning in mod_access.c
10076 [Florent Guillaume]
10078 *) Corrected several directives in sample srm.conf
10079 --- includes corrections to directory indexing icon-related directives
10080 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
10081 icons for encodings right, and turning on AddEncoding by default).
10084 *) Corrected descriptions of args to AddIcon and AddAlt in command table
10087 *) INSTALL & README mention "contributed modules" directory [Brian
10090 *) Fixed English in the license language... "for for" --> "for".
10093 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
10094 mod_alias.c, merging it almost completely with handling of Alias, and
10095 adding a 'notes' field to the request_rec which allows the CGI module
10096 to discover whether the Alias module has put this request through
10097 ScriptAlias (which it needs to know for back-compatibility, as the old
10098 NCSA code did not check Options ExecCGI in ScriptAlias directories).
10101 Changes with Apache 0.8.10 18 Aug 1995
10103 *) AllowOverride applies to the named directory, and not just
10104 subdirectories. [David Robinson]
10106 *) Do locking for accept() exclusion (on systems that need it)
10107 using a special file created for the purpose in /usr/tmp, and
10108 not the error log; using the error log causes real problems
10109 if it's NFS-mounted; this is known to be the cause of a whole
10110 lot of "server hang" problems with Solaris. [David Robinson;
10111 thanks to Merten Schumann for help diagnosing the problem].
10113 Changes with Apache 0.8.9 12 Aug 1995
10115 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
10117 *) Nested includes see environment variables of the including document,
10118 for NCSA bug-compatibility (some sites have standard footer includes
10119 which try to print out the last-modified date). [Eric Hagberg/Robert
10122 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
10123 URI as a CGI script, even if it would have been treated as something
10124 else if requested directly, for NCSA back-compatibility. (Note that
10125 this means that people who know the name of the script can see the
10126 code just by asking for it). [Robert Thau]
10128 *) New version of dbmmanage script included in support directory as
10131 *) Check if scoreboard file couldn't be opened, and say so, rather
10132 then going insane [David Robinson]
10134 *) POST to CGI works on A/UX [Jim Jagielski]
10136 *) AddIcon and AddAlt commands work properly [Rob Hartill]
10138 *) NCSA server push works properly --- the Arena bug compatibility
10139 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
10140 if you still want the workaround). [Rob Hartill]
10142 *) If client didn't submit any Accept-encodings, ignore encodings in
10143 content negotiation. (NB this will all have to be reworked anyway
10144 for the new HTTP draft). [Florent Guillaume]
10146 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
10148 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
10150 *) Give Redirect priority over Alias, for NCSA bug compatibility
10153 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
10154 paralleling earlier bug fix for CGI [David Robinson]
10156 *) If DBM auth is improperly configured, report a server error and don't
10159 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
10160 it seems to work well enough without it (even in a 10 hits/sec
10161 workout), and the overhead for the locking under A/UX is
10162 alarmingly high (though it is very low on other systems).
10163 [Eric Hagberg, Jim Jagielski]
10165 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
10167 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
10168 Behlendorf/Eric Hagberg]
10170 *) More improvements to default Configuration for A/UX [Jim Jagielski]
10172 *) Compiles clean on NEXT [Rob Hartill]
10174 *) Compiles clean on SGI [Robert Thau]
10176 Changes with Apache 0.8.8 08 Aug 1995
10178 *) SunOS library prototypes now never included unless explicitly
10179 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
10180 people using GNU libc on SunOS are screwed by prototypes for the
10183 (Those who wish to compile clean with gcc -Wall on a standard
10184 SunOS setup need the prototypes, and may obtain them using
10185 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
10186 with nonstandard libraries are presumably competent to make their
10189 *) Strips trailing '/' characters off both args to the Alias command,
10190 to make 'Alias /foo/ /bar/' work.
10192 Changes with Apache 0.8.7 03 Aug 1995
10194 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
10195 [reported by David Robinson]
10197 *) Compiles clean on OSF/1 [David Robinson]
10199 *) Added some of the more recent significant changes (AddLanguage stuff,
10200 experimental LogFormat support) to CHANGES file in distribution root
10203 Changes with Apache 0.8.6 02 Aug 1995
10205 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10206 (If you actually wanted a conditional GET which bypassed the cache, you
10207 couldn't get it). [Reported by Roy Fielding]
10209 *) Properly terminate headers on '304 Not Modified' replies to conditional
10210 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10211 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10213 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10215 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10216 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10217 and older versions don't set the __SUNPRO_C preprocessor variable). On
10218 all other systems, these are never used anyway. [Reported by Mark Cox].
10220 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10222 Changes with Apache 0.8.5 01 Aug 1995
10224 *) Added last-minute configurable log experiment, as optional module
10226 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10227 properly. (One-line fix to http_protocol.c).
10229 *) Work around bogus behavior when reloading from Netscape.
10230 It's Netscape's bug --- for some reason they expect a request with
10231 If-modified-since: to not function as a conditional GET if it also
10232 comes with Pragma: no-cache, which is way out of line with the HTTP
10233 spec (according to Roy Fielding, the redactor).
10235 *) Added parameter to set maximum number of server processes.
10237 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10240 *) IdentityCheck bugfix [Chuck Murcko].
10242 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10244 *) More sample config file corrections; add extension to AddType for
10245 *.asis, move AddType generic description to its proper place, and
10246 fix miscellaneous typos. [ Alexei Kosut ]
10248 *) Deleted the *other* reference to the regents from the Berkeley
10249 legal disclaimer (everyplace).
10251 *) Nuked Shambhala name from src/README; had already cleaned it out
10252 of everywhere else.
10254 Changes with Apache 0.8.4
10256 *) Changes to server-pool management parms --- renamed current
10257 StartServers to MinSpareServers, created separate StartServers
10258 parameter which means what it says, and renamed MaxServers to
10259 MaxSpareServers (though the old name still works, for NCSA 1.4
10260 back-compatibility). The old names were generally regarded as
10261 too confusing. Also altered "docs" in sample config files.
10263 *) More improvements to default config files ---
10264 sample directives (commented out) for XBitHack, BindAddress,
10265 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10266 defaults, AddTypes for send-as-is and imagemap magic types, and
10267 improvements to samples for DirectoryIndex [Alexei Kosut]
10269 *) Yet more improvements to default config files --- changes to
10270 Alexei's sample AddLanguage directives, and sample LanguagePriority
10271 [ Florent Guillaume ]
10273 *) Set config file locations properly if not set in httpd.conf
10276 *) Don't escape URIs in internal redirects multiple times; don't
10277 do that when translating PATH_INFO to PATH_TRANSLATED either.
10280 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10282 Changes with Apache 0.8.3
10284 *) Edited distribution README to *briefly* summarize installation
10285 procedures, and give a pointer to the INSTALL file in the src/
10288 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10289 recent NCSA distributions.
10291 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10292 exist for the same directory, use both and don't segfault. [Reported
10295 *) Proper makefile dependencies [David Robinson]
10297 *) Note (re)starts in error log --- reported by Rob Hartill.
10299 *) Only call no2slash() after get_path_info() has been done, to
10300 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10301 reported by Andrew Wilson, though this one is probably a real bug]
10303 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10304 dump core when Referer is not supplied. [Randy Terbush]
10306 *) Lightly edited sample config files to refer people to our documentation
10307 instead of NCSA's, and to list Rob McCool as *original* author (also
10308 deleted his old, and no doubt non-functional email address). Would be
10309 nice to have examples of new features...
10311 Changes with Apache 0.8.2 19 Jul 1995
10313 *) Added AddLanuage code [Florent Guillaume]
10315 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10317 *) All sorts of problems when MultiViews finds a directory. It would
10318 be nice if mod_dir.c was robust enough to handle that, but for now,
10319 just punt. [reported by Brian Behlendorf]
10321 *) Wait for all children on restart, to make sure that the old socket
10322 is gone and we can reopen it. [reported by Randy Terbush]
10324 *) Imagemap module is enabled in default Configuration
10326 *) RefererLog and UserAgentLog modules properly default the logfile
10329 *) Mark Cox's mod_cookies added to the distribution as an optional
10330 module (commented out in the default Configuration, and noted as
10331 an experiment, along with mod_dld). [Mark Cox]
10333 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10335 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10337 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10339 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10342 Changes with Apache 0.8.1
10344 *) New imagemap module [Randy Terbush]
10346 *) Replacement referer log module with NCSA-compatible RefererIgnore
10347 [Matthew Gray again]
10349 *) Don't mung directory listings with very long filenames.
10350 [Florent Guillaume]
10352 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10354 *) New config script. See INSTALL for info. [Robert Thau]
10356 *) Scoreboard mechanism for regulating the number of extant server
10357 processes. MaxServers and StartServers defaults are the same as
10358 for NCSA, but the meanings are slightly different. (Actually,
10359 I should probably lower the MaxServers default to 10).
10361 Before asking for a new connection, each server process checks
10362 the number of other servers which are also waiting for a
10363 connection. If there are more than MaxServers, it quietly dies
10364 off. Conversely, every second, the root, or caretaker, process
10365 looks to see how many servers are waiting for a new connection;
10366 if there are fewer than StartServers, it starts a new one. This
10367 does not depend on the number of server processes already extant.
10368 The accounting is arranged through a "scoreboard" file, named
10369 /tmp/htstatus.*, on which each process has an independent file
10370 descriptor (they need to seek without interference).
10372 The end effect is that MaxServers is the maximum number of
10373 servers on an *inactive* server machine, but more will be forked
10374 off to handle unusually heavy loads (or unusually slow clients);
10375 these will die off when they are no longer needed --- without
10376 reverting to the overhead of full forking operation. There is a
10377 hard maximum of 150 server processes compiled in, largely to
10378 avoid forking out of control and dragging the machine down.
10379 (This is arguably too high).
10381 In my server endurance tests, this mechanism did not appear to
10382 impose any significant overhead, even after I forced it to put the
10383 scoreboard file on a normal filesystem (which might have more
10384 overhead than tmpfs). [Robert Thau]
10386 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10389 *) Read .htaccess files even in directory with <Directory> section.
10390 (Former incompatibility noted on mailing list, now fixed). [Robert
10393 *) "HEAD /" gives the client a "Bad Request" error message, rather
10394 than trying to send no body *and* no headers. [Cliff Skolnick].
10396 *) Don't produce double error reports for some very obscure cases
10397 mainly involving auth configuration (the "all modules decline to
10398 handle" case which is a sure sign of a server bug in most cases,
10399 but also happens when authentication is badly misconfigured).
10402 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10403 it's *for*, and this sort of thing really shouldn't be cluttering
10404 up the Makefile). [Robert Thau]
10406 *) Incidental code cleanups in http_main.c --- stop dragging
10407 sa_client around; just declare it where used. [Robert Thau]
10409 *) Another acc-related fix. (It doesn't like const char
10410 in some places...). [Mark Cox]
10412 Changes with Shambhala 0.6.1 13 Jul 1995
10414 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10415 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10417 *) Compiles clean with acc on SunOS [Paul Sutton]
10419 *) Reordered modules in modules.c so that Redirect takes priority
10420 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10421 believe it or not, he has an actual site with a ScriptAlias and
10422 a Redirect declared for the *exact same directory*. Even *my*
10423 compatibility fetish wouldn't motivate me to fix this if the fix
10424 required any effort, but it doesn't, so what the hey.
10426 *) Fixed to properly default several server_rec fields for virtual
10427 servers from the corresponding fields in the main server_rec.
10428 [Cliff Skolnick --- 'port' was a particular irritant].
10430 *) No longer kills off nph- child processes before they are
10431 finished sending output. [Matthew Gray]
10433 Changes with Shambhala 0.6.0 10 Jul 1995
10435 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10436 the connection to the client in an "aborted" state, but otherwise
10437 allow whatever handlers are running to clean up. hard_timeout()s
10438 abort the request in progress completely; anything not tied to some
10439 resource pool cleanup will leak. They're still around because I
10440 haven't yet come up with a more elegant way of handling
10441 timeouts when talking to something that isn't the client. The
10442 default_handler and the dir_handler now use soft timeouts, largely
10443 so I can test the feature. [Robert Thau]
10445 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10446 the case of log handlers dying prematurely is probably handled VERY
10447 gracelessly at this point, and if the logger stops reading input,
10448 the server will hang. (It is known to correctly restart the
10449 logging process on server restart; this is (should be!) going through
10450 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10451 script). [Robert Thau]
10453 *) asis files supported (new module). [Robert Thau]
10455 *) IdentityCheck code is compiled in, but has not been tested. (I
10456 don't know anyone who runs identd). [Robert Thau]
10458 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10459 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10461 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10463 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10464 as timeouts are not in scope. [Robert Thau]
10466 *) quoted-string args in config files now handled correctly (doesn't drop
10467 the last character). [Robert Thau; reported by Randy Terbush]
10469 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10470 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10472 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10473 default default type); the former default default behavior when all
10474 type-checkers defaulted had been a core dump. [Paul Sutton]
10476 *) Copy filenames out of the struct dirent when indexing
10477 directories. (On Linux, readdir() returns a pointer to the same
10478 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10480 Changes with Shambhala 0.5.3 [not released]
10482 *) Default response handler notes "file not found" in the error log,
10483 if the file was not found. [Cliff Skolnick].
10485 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10486 code no longer sets up bogus PATH_INFO which fakes out the directory
10487 handler). [Cliff Skolnick]
10489 Changes with Shambhala 0.5.2 06 Jul 1995
10491 *) Changes to http_main.c --- root server no longer plays silly
10492 games with SIGCHLD, and so now detects and replaces dying
10493 children. Child processes just die on SIGTERM, without taking
10494 the whole process group with them. Potential problem --- if any
10495 child process refuses to die, we hang in restart.
10496 MaxRequestsPerChild may still not work, but it certainly works
10497 better than it did before this! [Robert Thau]
10499 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10500 work (or work better, at least); over-long description lines
10501 properly terminated. [Mark Cox]
10503 *) http_request.c now calls unescape_url() more places where it
10504 should [Paul Sutton].
10506 *) More directory handling bugs (reported by Cox)
10507 Parent Directory link is now set correctly. [Robert Thau]
10509 Changes with Shambhala 0.5.1 04 Jul 1995
10511 *) Generalized cleanup interface in alloc.c --- any function can be
10512 registered with alloc.c as a cleanup for a resource pool;
10513 tracking of files and file descriptors has been reimplemented in
10514 terms of this interface, so I can give it some sort of a test.
10517 *) More changes in alloc.c --- new cleanup_for_exec() function,
10518 which tracks down and closes all file descriptors which have been
10519 registered with the alloc.c machinery before the server exec()s a
10520 child process for CGI or <!--#exec-->. CGI children now get
10521 started with exactly three file descriptors open. Hopefully,
10522 this cures the problem Rob H. was having with overly persistent
10523 CGI connections. [Robert Thau]
10525 *) Mutual exclusion around the accept() in child_main() --- this is
10526 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10527 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10528 This uses fcntl(F_SETLK,...) on the error log descriptor because
10529 flock() on that descriptor won't work on systems which have BSD
10530 flock() semantics, including (I think) Linux 1.3 and Solaris.
10532 This does work on SunOS (when the server is idle, only one
10533 process in the pool is waiting on accept()); it *ought* to work
10534 on the other systems. [Robert Thau]
10536 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10538 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10540 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10542 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10543 be unnecessary if I go to the revised timeout-handling scheme).
10546 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10547 string) even if none came in with the request. [Robert Thau]
10549 *) CHANGES file added to distribution ;-).
10551 Changes with Shambhala 0.4.5
10553 *) mod_dld --- early dynamic loading support [rst]
10554 *) Add wildcard content handlers for XBITHACK; default_hander now
10555 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10556 *) XBITHACK supported as a wildcard content-handler, and
10557 configurable at run-time (not just at compile time, as in the
10558 "patchy server" releases) [rst]
10560 Changes with Shambhala 0.4.4 30 Jun 1995
10562 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10563 *) Handle Addtype x/y .z [rst, reported by Cox]
10565 Changes with Shambhala 0.4.3
10567 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10568 synonymous [rst, terbush]
10570 Changes with Shambhala 0.4.1 28 Jun 1995
10572 *) First-cut virtual host implementation; some refit in the config
10573 reading code, and log management, was necessary to support this [rst]
10574 *) Sub-pool machinery, originally added to avoid excessive storage
10575 allocation on listings of large directories (which turned out to
10576 be the problem that the 0.3 storage accounting was added to
10577 find). Subrequests and mod_dir changed to use subpools. [rst]
10578 *) More memory debugging --- free list consistency checks. [rst]
10579 *) Added err_headers to request_rec, with support elsewhere [rst]
10580 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10582 Changes with Shambhala 0.3 19 Jun 1995
10584 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10585 *) Don't compile in mod_ai_backcompat by default
10586 *) Switch name of server from Apache to Shambhala in Makefile
10587 *) Add some accounting routines to track memory usage in the pools,
10590 Changes with Shambhala 0.2
10592 *) Set DOCUMENT_ROOT CGI variable
10593 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10594 *) Add critical section protection to handling of cleanup structures
10596 *) Significant code reorg within the server core to group related
10597 functions together [rst]
10598 *) Correctly handle clients that hang up before sending any request
10600 *) Replace dying child processes. [rst]
10602 Changes with Shambhala 0.1 12 Jun 1995
10604 Major rewrite of the pre-existing "patchy server" codebase, by
10605 Robert Thau (rst). Significant portions of the server code, such
10606 as configuration-file handling and HTTP authentication support,
10607 were ripped out and rewritten from scratch. Code that was not
10608 completely rewritten was significantly altered.
10610 Major changes with this release include:
10612 *) Introduction of the module API; in request handling, the central
10613 machinery just dispatches to various modules, which actually do
10614 most of the work. Configuration handling is similar --- modules
10615 declare their own commands, and the central machinery just
10616 dispatches to them.
10618 API features from shambhala/0.1 were substantially unchanged in
10619 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10620 release, such as wildcard handlers and subpools, were added in
10621 subsequent Shambhala releases, and were also generally rst's
10624 *) This release included the following modules:
10626 mod_access (access control --- allow and deny directives),
10627 mod_alias (Alias and Redirect commands),
10628 mod_auth (straight HTTP authentication, based on flat-files)
10629 mod_auth_dbm (same, with dbm files)
10630 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10631 mod_common_log (CLF access logs; later renamed mod_log_common)
10632 mod_dir (directory indexing)
10633 mod_include (server-side includes)
10634 mod_mime (AddType directives)
10635 mod_negotiation (content negotiation)
10636 mod_userdir (support for users' public_html directories)
10638 It also included a mod_ai_backcompat, which was a private hack
10639 for back-compatibility with rst's own AI-lab servers.
10641 All of these modules were substantially complete, and functional
10642 or nearly so (a few, which implemented features not in use at
10643 Thau's site, required patches of a few lines).
10645 *) sub-request machinery, to allow modules to determine how other
10646 modules would assign MIME types to a given file, or optionally
10647 serve its content (this is heavily used by mod_dir, mod_include
10648 and mod_negotiation).
10650 *) Resource pool system for keeping track of memory allocated and
10651 files opened in service of a particular request. Much of the
10652 code in the modules (when they weren't rewrites) was adjusted to
10653 replace a pervasive convention of using fixed-size buffers on
10654 the stack with an equally pervasive convention of using memory
10655 allocated with palloc().
10657 *) Reorganization of data structures associated with a given
10658 request to eliminate use of global variables and the troublesome
10659 unmunge_name function (used in NCSA and early Apache releases to
10660 attempt to determine the URI which mapped to a given filename
10661 --- a difficult proposition, given that it is easy to produce
10662 setups in which multiple URIs map to the same file).
10664 *) Source files renamed and rearranged
10666 *) Very simple pre-forking behavior --- parent process forked off a
10667 fixed number of children, and then just waited for SIGHUP.
10669 *) Other more minor changes too numerous to list.
10671 This release included modified versions of a lot of code from the
10672 Apache 0.6.4 public release, plus an early pre-forking patch
10673 codeveloped by Robert Thau and Rob Hartill.
10675 Changes with Apache 0.7.3 20 Jun 1995
10677 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10678 were incorporated by Rob Hartill on the main branch while Robert Thau
10679 worked on the Shambhala rewrite above. Most were merged into the
10680 Shambala architecture after Apache 0.8.0.
10682 Changes with Apache 0.6.4 13 May 1995
10684 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10687 Changes with Apache 0.5.1 10 Apr 1995
10689 Changes with Apache 0.4 02 Apr 1995
10691 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10694 Changes with Apache 0.3 24 Mar 1995
10696 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10699 Changes with Apache 0.2 18 Mar 1995
10701 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10702 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10703 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
