1 Changes with Apache 2.0.30-dev
3 *) Fix a segfault in the worker MPM that could happen during
4 child process exits. [Brian Pane, Aaron Bannert]
6 *) Allow mod_auth_dbm to handle multiple DBM types [Ian Holsman]
8 *) Fix matching of vhosts by ip address so we find IPv4
9 vhost address when target address is v4-mapped form of
10 that address. [Jeff Trawick]
12 *) More performance tweaks to the BNDM string-search algorithm
13 used to find "<!--#" tokens in mod_include [Brian Pane]
15 *) Miscellaneous small performance fixes: optimized away various
16 string copy operations and removed large temp buffers from
17 the stack [Brian Pane]
19 *) Fixed startup segfault that occurred when a VirtualHost
20 directive had a port but no address [Brian Pane]
22 *) Allow htdbm to work with multiple DBM types [Ian Holsman]
24 *) Win32: Made change to apr_sendfile() to return APR_ENOTIMPL
25 if oslevel < WINNT. This should fix several problems reported
26 Against 2.0.28 on Windows 98 [Bill Stoddard]
28 *) Win32: Fix bug that could cause CGI scripts with QUERY_STRINGS
29 to fail. [Bill Stoddard]
31 *) Change core code to allow an MPM to set hard thread/server
32 limits at startup. prefork, worker, and perchild MPMs now have
33 directives to set these limits. [Jeff Trawick]
35 *) Win32: The async AcceptEx() event should be autoreset upon
36 successful completion of a wait (WaitForSingleObject). This
37 eliminates a number of spurious
38 setsockopt(SO_UPDATE_ACCEPT_CONTEXT) failed." messages.
41 *) Move any load library path environment variables out of
42 apachectl and into a separate environment variable file which
43 can be more easily tailored by the admin. The environment
44 variable file as built by Apache may have additional system-
45 specific settings. For example, on OS/390 we tailor the heap
46 settings to allow lots of threads. [Jeff Trawick]
48 *) Use the new APR pool code to reduce pool-related lock
49 contention in the worker MPM. [Sander Striker]
51 *) The POD no longer assumes the child is listening on 127.0.0.1
52 and now pulls the first hostname in the list of listeners to
53 perform the dummy connect on. This fixes a bug when the user
54 had configured the Listen directive for an IP other than
55 127.0.0.1. This would result in undead children and error
56 messages such as "Connection refused: connect to listener".
59 *) The worker MPM now respects the LockFile setting, needed to
60 avoid locking problems with NFS. [Jeff Trawick]
62 *) Fix segfault when worker MPM receives SIGHUP.
63 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
65 *) Fix bug that could potentially prevent the perchild MPM from
66 working with more than one vhost/uid. [Aaron Bannert]
68 *) Change make install and apxs -i processing of DSO modules to
69 perform special handling on platforms where libtool doesn't install
70 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
71 which prevented standard LoadModule statements from working.
74 *) Whenever mod_so is enabled (not just when there are DSOs for
75 our modules), do whatever special magic is required for compiling/
76 loading third-party modules. This allows third-party DSOs to
77 be used on an AIX build when there were no built-in modules
78 built as DSOs. (This should help on OS/390 and BeOS as well.)
81 *) Allow apxs to be used to build DSOs on AIX without requiring the
82 user to hard-code the list of import files. (This should help
83 on OS/390 and BeOS as well.) [Jeff Trawick]
85 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
86 PR 8563, 8919 [William Rowe]
88 *) Get binary builds working when libapr and libaprutil are built
91 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
92 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
93 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
95 *) Fix the handling of SSI directives in which the ">" of the
96 terminating "-->" is the last byte in a file [Brian Pane]
98 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
99 message that we had back in apache-1.3 and still have scattered
100 throughout our docs. [Aaron Bannert]
102 *) Prevent the Win32 port from continuing after encountering an
103 error in the command line args to apache. [William Rowe]
105 *) On a error in the proxy, make it write a line to the error log
108 Changes with Apache 2.0.29
110 *) Add buffering in core_output_filter to ensure that long
111 lists of small buckets don't cause small packet writes.
112 [Brian Pane, Ryan Bloom]
114 *) Fix the installation target to make sure that the manual is
115 installed in the correct location.
116 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
117 Gomez Henri <hgomez@slib.fr>]
119 *) Fix the cmd command for mod_include. When we are processing
120 a cmd command, we do not want to use the r->filename to set
121 the command name. The command comes from the SSI tag. To do this,
122 I added a variable to the function that builds the command line
123 in mod_cgi. This allows the include_cmd function to specify
124 the command line itself. [Ryan Bloom]
126 *) Change open_logs hook to return a value, allowing you
127 to flag a error while opening logs
128 [Ian Holsman, Doug MacEachern]
130 *) Change post_config hook to return a value, allowing you
131 to flag a error post config
132 [Ian Holsman, Jeff Trawick]
134 *) Allow SUEXEC_BIN (the path to the suexec binary that is
135 hard-coded into the server) to be specified to the configure
136 script by the --with-suexec-bin parameter. [Aaron Bannert]
138 *) Fix segv in worker MPM following accept on pipe-of-death
141 *) Add mod_deflate to experimental.
142 [Ian Holsman, Justin Erenkrantz]
144 *) Bail out at configure time if an invalid MPM was specified.
145 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
147 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
148 configured [John Sterling <sterling@covalent.net>]
150 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
152 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
154 *) Optimization for the BNDM string-search function in
155 mod_include. [Brian Pane]
157 *) Fixed the behavior of the XBitHack directive.
158 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
160 *) The threaded MPM for Unix has been removed. Use the worker
161 MPM instead. [various]
163 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
164 in logging the error from a failed DNS lookup. [Jeff Trawick]
166 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
169 *) Get mod_cgid killed when a MPM exits due to a fatal error.
172 *) Fix a file descriptor leak in mod_include. When we include a
173 file, we use a sub-request, but we didn't destroy the sub-request
174 immediately, instead we waited until the original request was
175 done. This patch closes the sub-request as soon as the data is
176 done being generated. [Brian Pane <bpane@pacbell.net>]
178 *) Allow modules that add sockets to the ap_listeners list to
179 define the function that should be used to accept on that
180 socket. Each MPM can define their own function to use for
181 the accept function with the MPM_ACCEPT_FUNC macro. This
182 also abstracts out all of the Unix accept error handling
183 logic, which has become out of synch across Unix MPMs.
186 *) Fix a bug which would cause the response headers to be omitted
187 when sending a negotiated ErrorDocument because the required
188 filters were attached to the wrong request_rec.
189 [John Sterling <sterling@covalent.net>]
191 *) Remove commas from the end of the macros that define
192 directives that are used by MPMs. Prior to this patch,
193 you would use these macros without commas, which was unlike
194 the macros for any other directives. Now, the caller provides
195 the comma rather than the macro providing it. This makes
196 the macros look more like the rest of the directives.
197 [Ryan Bloom and Cliff Woolley]
199 *) Add 'redirect-carefully' environment option to disable sending
200 redirects under special circumstances. This is helpful for
201 Microsoft's WebFolders when accessing a directory resource via
202 DAV methods. [Justin Erenkrantz]
204 *) Begin to abstract out the underlying transport layer.
205 The first step is to remove the socket from the conn_rec,
206 the server now lives in a context that is passed to the
207 core's input and output filters. This forces us to be very
208 careful when adding calls that use the socket directly,
209 because the socket isn't available in most locations.
212 *) Really reset the MaxClients value in worker and threaded
213 when the configured value is not a multiple of the number
214 of threads per child. We said we did previously but we
215 forgot to. [Jeff Trawick]
217 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
219 *) If shared modules are requested and mod_so is not available,
220 produce a fatal config-time error. [Justin Erenkrantz]
222 *) Improve http2env's performance by cutting the work it has to
223 do. [Brian Pane <bpane@pacbell.net>]
225 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
226 [Brian Pane <bpane@pacbell.net>]
228 Changes with Apache 2.0.28
230 *) Fix infinite loop in mod_cgid.c.
231 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
233 *) When no port is given in a "ServerName host" directive, the
234 server_rec->port is now set to zero, not 80. That allows for
235 run-time deduction of the correct server port (depending on
236 SSL/plain, and depending also on the current setting of
237 UseCanonicalName). This change makes redirections
238 work, even with https:// connections. As in Apache-1.3, the
239 connection's actual port number is never used, only the ServerName
240 setting or the client's Host: setting. Documentation updated
241 to reflect the change. [Martin Kraemer]
243 *) Add a '%{note-name}e' argument to mod-headers, which works in
244 the same way as mod_log_confg. [Ian Holsman]
246 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
247 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
248 MPMs. [Cliff Woolley]
250 *) Introduce htdbm, a user management utility for db/dbm authorization
251 databases. [Mladen Turk <mturk@mappingsoft.com>]
253 *) Optimize usage of strlen and strcat in ap_directory_walk.
254 [Brian Pane <bpane@pacbell.net>]
256 Changes with Apache 2.0.27
258 *) Introduce an Apache mod_ssl initial configuration template
259 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
261 *) Fixed a memory leak in the getline parsing code that could
262 be triggered by arbitrarily large header lines. Requests
263 from the core input filter for single lines are now limited
264 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
266 *) Fix a truncation bug in how we print the port on the Via: header.
267 The routine that prints the Via: header now takes a length for
268 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
270 *) Some syntax errors in mod_mime_magic's magic file can result
271 in a 500 error, which previously was unlogged. Now we log the
272 error. [Jeff Trawick]
274 *) Add the support/checkgid helper app, which checks the run-time
275 validity of group identifiers usable in the Group directive.
278 *) Various --enable-so options have been fixed: --enable-so is
279 treated as "static"; explicit --enable-so=shared issues an error;
280 and explicit --enable-so fails with error on systems without
281 APR_HAS_DSO. [Aaron Bannert]
283 *) Fix a segfault in the core input filter when the client socket
284 gets disconnected unexpectedly. [Cliff Woolley]
286 *) Fix the reporting for child processes that die. This removes
287 all of the non-portable W* macros from Apache.
288 [Jeff Trawick and Ryan Bloom]
290 *) Win32: Track and display "Parent Server Generation:" in
291 mod_status output. The generation will be bumped at
292 server graceful restart, when the child process exits
293 by hitting MaxRequestsPerChild or if the child
294 process exits abnormally. [Bill Stoddard]
296 *) Win32: Fix problem where MaxRequestsPerChild directive was
297 not being picked up in favor of the default. Enable
298 the parent to start up a new child process immediately upon
299 the old child starting shutdown.
302 *) Fix some bungling of the remote port in rfc1413.c so that
303 IdentityCheck retrieves the proper user id instead of failing
304 and thus always returning "nobody."
305 [Dick Streefland <Dick.Streefland@xs4all.nl>]
307 *) Introduced thread saftey for mod_rewrite's internal cache.
308 [Brian Pane <bpane@pacbell.net>]
310 *) Simplified mod_env's directives to behave as most directives are
311 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
312 directive following that UnsetEnv within the same container.
313 Also provides a runtime startup warning if a PassEnv configured
314 environment value is undefined. [William Rowe]
316 *) The worker MPM is now completely ported to APR's new lock API. It
317 uses native APR types for thread mutexes, cross-process mutexes,
318 and condition variables. [Aaron Bannert]
320 *) Sync up documentation to remove all references to the now deprecated
321 Port directive. [Justin Erenkrantz]
323 *) Moved all ldap modules from the core to httpd-ldap sub-project
326 *) Exit when we can't listen on any of the configured ports. This
327 is the same behavior as 1.3, and it avoids having the MPMs to
328 deal with bogus ap_listen_rec structures. [Jeff Trawick]
330 *) Cleanup the proxy code that creates a request to the origin
331 server. This change adds an optional hook, which allows modules
332 to gain control while the request is created if the proxy module
333 is loaded. The purpose of this hook is to allow modules to add
334 input and/or output filters to the request to the origin. While
335 I was at it, I made the core use this hook, so that proxy request
336 creation uses some of the code from the core. This can still be
337 greatly improved, but this is a good start. [Ryan Bloom]
339 Changes with Apache 2.0.26
341 *) Port the MaxClients changes from the worker MPM to the threaded
344 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
345 with the new input filtering system. [Justin Erenkrantz]
347 *) Introduce the MultiviewsMatch directive, to allow the operator
348 to be flexible in recognizing Handlers and Filters filename
349 extensions as part of the Multiviews matching logic, strict with
350 MultiviewsMatch NegotiatedOnly to accept only filename extentions
351 that designate negotiated parameters, (content type, charset, etc.)
352 or MultiviewsAll for the 1.3 behavior of matching any files, even
353 if they have unregistered extensions. [William Rowe]
355 *) Fixed the configure script to add a LoadModule directive to
356 the default httpd.conf for any module that was compiled
357 as a DSO. [Aaron Bannert <aaron@clove.org>]
359 *) rewrite mod_ssl input filtering to work with the new input filtering
360 system. [Justin Erenkrantz]
362 *) prefork: Don't segfault when we are able to listen on some but
363 not all of the configured ports. [Jeff Trawick]
365 *) Build mod_so even if no core modules are built shared.
366 [Aaron Bannert <aaron@clove.org>]
368 *) Introduce ap_directory_walk rewrite (with further optimizations
369 required) to adapt to the ap_process_request_internal() changes.
370 Optimized so subrequests and redirects now reuse previous section
371 merges, until we mismatch with the original directory_walk, and
372 precomputed r->finfo results will cause directory_walk to skip
373 the most expensive phases of the function. [William Rowe]
375 *) Allow ApacheMonitor to connect to and control Apache on other
376 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
378 *) Remove the Port directive. In it's place, the Listen directive
379 is now a required directive, which tells Apache what port to
380 listen on. The ServerName directive has also been extended
381 to accept an optional port. If the port is specified to the
382 ServerName, the server will report that port whenever it
383 reports the port that it is listening on. This change was
384 made to ease configuration errors that stem from having a Port
385 directive, and a Listen directive. In that situation, the server
386 would only listen to the port specified by the Listen command,
387 which caused a lot of confusion to users. [Ryan Bloom]
389 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
390 build, as loadable modules. [William Rowe]
392 *) Fix --enable-mods-shared processing. If most is specified,
393 then all modules that can be compiled as shared modules are.
394 [Aaron Bannert <aaron@clove.org>]
396 *) Update the mime.types file to map video/vnd.mpegurl to mxu
397 and add commonly used audio/x-mpegurl for m3u extensions.
398 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
400 *) Eliminate the depreciated r->content_language, in favor of the array
401 r->content_languages introduced many years ago. Module authors must
402 substantially overhaul their modules, so this needs to be upgraded
403 if the module still relied on backwards-brokeness. [William Rowe]
405 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
408 *) Rewrite the input filtering mechanisms to consolidate and reorganize
409 code. In short, core_input_filter does something now and
410 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
412 *) Update the Win32 build to re-absorb mod_proxy and family.
415 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
416 current SDK.) [William Rowe]
418 *) Some style changes to the code that does ProxyErrorOverride. Fixed
419 config merge behaviour. [Graham Leggett]
421 *) Allow support programs to be compiled against a static version
422 of libapr. This allows the smaller support programs to be
423 relocated. [Aaron Bannert <aaron@clove.org>]
425 *) Update the mime.types file to the registered media types as
426 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
428 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
429 number of clients that can connect at the same time, instead of
430 specifying the maximum number of child processes.
431 [Aaron Bannert <aaron@clove.org>]
433 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
434 be consistent with 1.3. [Justin Erenkrantz]
436 *) Cache apr_explode_localtime() value for 15 seconds.
437 [Brian Pane <bpane@pacbell.net>]
439 *) Fix mod_include to not return ETag or Last-Modified headers.
440 [Ian Holsman <ianh@cnet.com>]
442 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
444 *) Eliminate the wasteful run-time conversion of method names from strings
445 to numbers in places where the methods are known at compile time.
446 [Brian Pane <bpane@pacbell.net>]
448 *) Turn the worker MPM's queue into a LIFO. This may
449 improve cache-hit performance under some conditions.
450 [Aaron Bannert <aaron@clove.org>]
452 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
453 support it. [Justin Erenkrantz]
455 *) Cleanup the worker MPM. We no longer re-use transaction
456 pools. This incurs less overhead than shuffling the pools
457 around so that they can be re-used. Remove one of the
458 queue's condition variables. We just redefined the API to
459 state that you can't try to add more stuff than you allocated
460 segments for. [Aaron Bannert <aaron@clove.org>]
462 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
464 *) Fixed persistent connections when a request contains a body.
467 *) mod_dav uses a new API to speak to the backend provider for dead
468 property management. [Greg Stein]
470 *) Remove the Win32 script-processing exception from mod_cgi, and
471 roll build_command_line/build_argv_list into a unified, overrideable
472 ap_cgi_build_command optional function. [William Rowe]
474 *) Rewrite find_start_sequence to use a better search algorithm
475 to find the start tag. [Justin Erenkrantz]
477 *) Fix a seg fault in mod_include. When we are generating an
478 internal redirect, we must set r->uri to "", not a bogus
479 string, and not NULL. [Ryan Bloom]
481 *) Optimized location_walk, so subrequests, redirects and second passes
482 now reuse previous section merges on a <Location > by <Location >
483 basis, until we mismatch with the original location_walk.
486 *) Back out the 1.45 change to util_script.c. This change made
487 us set the environment variable REQUEST_URI to the redirected
488 URI, instead of the originally requested URI.
489 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
491 *) Make mod_include do lazy evaluation of potentially expensive to
492 compute variables. [Brian Pane <bpane@pacbell.net>]
494 *) Fix logging of bytes sent for HEAD requests. %b and %B should
495 log either - or 0, before this patch, they were both logging
496 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
498 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
499 than per character. [Brian Pane <bpane@pacbell.net>]
501 *) Normalize the primary request, redirects and sub-requests to
502 run the same ap_process_request_internal for consistency in
503 robustness, behavior and security. [William Rowe]
505 *) Fix a segfault with mod_include when r->path_info is not set
506 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
508 *) Add -X functionality back. This indicates to all MPMs and any other
509 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
511 *) Some initial support for the cygwin platform [prefork only].
512 This is not to be confused with support for the WinNT/Win32
513 platform, which is the recommended configuration for native
514 Win32 users. The cygwin platform support is recommended for
515 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
517 *) Changed syntax of Set{Input|Output}Filter. The list of filters
518 must be semicolon delimited (if more than one filter is given.)
519 The Set{Input|Output}Filter directive now overrides a parent
520 container's directive (e.g. SetInputFilter in <Directory /web/foo>
521 will override any SetInputFilter directive in <Directory /web>.)
522 This new syntax is more consistent with Add{Input|Output}Filter
523 directives defined in mod_mime. Also cures a bug in prior releases
524 where the Set{Input|Output}Filter directive would corrupt the
525 global configuration if the multiple directives were nested.
528 *) Cured what's ailed mime for quite some time. If an AddSomething
529 was given in the configuration (Language, Charset, Handler or
530 Encoding) Apache would set the content type as given by AddType,
531 but refused to check the mime.types file if AddType wasn't given
532 for that specific extension. Setting the AddHandler for .html
533 without setting the AddType text/html html would cause Apache to
534 use the default content type. [William Rowe]
536 *) Added some bulletproofing to memory allocation in the LDAP cache
537 code. [Graham Leggett]
539 Changes with Apache 2.0.25
541 *) Move the installed /manual directory out of the /htdocs/ tree, so
542 that it can be kept more independently from the remaining document
543 root. The "Alias /manual ..." already allowed for easy projection
544 into existing private document trees. [Martin Kraemer]
546 *) Add specified user attributes to the environment when using
547 mod_auth_ldap. This allows you to use mod_include to embed specified
548 user attributes in a page like so:
549 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
552 *) Fix a performance problem with the worker MPM. We now create
553 transaction pools once, and re-use them for each connection.
554 [Aaron Bannert <aaron@clove.org>]
556 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
557 of a 'handler' or 'filter', so that any filename extension that does
558 not contribute to the negotiated metadata can't be served without
559 an explicit request. E.g., if the .Z extension is associated with
560 an unzip filter, the user request somefile.Z.html, mod_negotiation
561 won't serve it. It can serve somefile.Z.html when somefile.Z is
562 requested, since the .Z extension is explictly requested, if the
563 .html extension is associated with ContentType text/html.
566 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
567 and corresponding AddOutputFilter syntax, to insert one or more
568 filters by mod_mime filename extension processing.
571 *) Fix a growing connection pool in core_output_filter() for
572 keepalive requests. [Jeff Trawick]
574 *) Moved split_and_pass_pretag_buckets back to being a
575 macro at Ryans's request. Removed the return from it
576 by setting and returning a return code instead. Updated
577 the code to check the return code from the macro and
578 do the right thing. [Paul J. Reder]
580 *) Fix a segfault when a numeric value was received for Host:.
583 *) Add a function ap_remove_input_filter. This is to match
584 up with ap_remove_output_filter. [Ryan Bloom]
586 *) Clean up location_walk, so that this step performs a minimum
587 amount of redundant effort (it must be run twice, but it will no
588 longer reparse all <Location > blocks when the request uri
589 hadn't changed.) [William Rowe]
591 *) Eliminate proxy: (and all other 'special') processing from the
592 ap_directory_walk() phase. Modules that want to use special
593 walk logic should refer to the mod_proxy map_to_location example,
594 with it's proxy_walk and proxysection implementation. This makes
595 either directory_walk flavor much more legible, since that phase
596 only runs against real <Directory > blocks.
599 *) Fix a security problem in mod_include which would allow
600 an SSI document to be passed to the client unparsed.
601 [Cliff Woolley, Brian Pane]
603 *) Introduce the map_to_storage hook, which allows modules to bypass
604 the directory_walk and file_walk for non-file requests. TRACE
605 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
606 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
609 *) Add the ability for mod_include to add the INCLUDES filter
610 if the file is configured for the server-parsed handler.
611 This makes the configuration for .shtml files much easier
612 to understand, and allows mod_include to honor Apache 1.3
613 config files. Based on Doug MacEachern's patch to PHP
614 to do the same thing. [Ryan Bloom]
616 *) force OpenSSL to ignore process local-caching and to always
617 get/set/delete sessions using mod_ssl's callbacks
618 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
619 Geoff Thorpe <geoff@geoffthorpe.net>]
621 *) Make the worker MPM shutdown and restart cleanly. This also
622 cleans up some race conditions, and gets the worker using
623 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
625 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
627 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
629 *) Fix for mod_include. Ryan's patch to check error
630 codes put a return in the wrong place. Also, the
631 include handler return code wasn't being checked.
632 I don't like macros with returns, so I converted
633 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
634 [Paul J. Reder <rederpj@raleigh.ibm.com>]
636 *) fix segv in mod_mime if no AddTypes are configured
637 [John Sterling <sterling@covalent.net>]
639 *) Enable ssl client authentication at SSL_accept time
640 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
642 *) Fix a segfault in mod_include when the original request has no
643 associated filename (e.g., we're filtering the error document for
644 a bad URI). [Jeff Trawick]
646 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
648 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
649 of httpd is started and shuts down due to socket conflict. Moving the
650 call to ap_log_pid solves the problem.
652 *) Changed the late-1.3 log_config substitution %c to %X, to log the
653 status of the closed connection, as it conflicts with the far more
654 common, historical ssl logging directive %...{var}c. [William Rowe]
656 *) Added the common error/ tree to the build/install targets
657 (similar to the common icons/ tree) for the multi-language error
658 messages that Lars committed earlier. [William Rowe]
660 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
662 *) Added a default commented-out mod_ldap and mod_auth_ldap
663 configuration to httpd-std.conf and httpd-win.conf
666 *) Added documentation for mod_ldap and mod_auth_ldap.
669 *) Enabled negative caching on attribute comparisons in the LDAP cache.
670 Fixed a problem where the default cache TTL was set in milliseconds
671 not microseconds causing the cache to time out almost immediately.
674 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
675 module code to follow APR. [Graham Leggett]
677 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
678 cleaned up when the connection pool pool is cleaned up.
681 *) Fix a minor issue with Jeff Trawick's mod_include
682 patch. Without this patch, the code will just allocate
683 more bytes in get_combined_directive than are needed.
686 *) Added the LDAP authentication module mod_auth_ldap.
687 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
689 *) Added the LDAP cache and connection pooling module mod_ldap.
690 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
692 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
693 by allowing a module to disable itself if its prerequisites are not
694 met. [Justin Erenkrantz]
696 Changes with Apache 2.0.24
698 *) Fix a couple of issues in mod_include when the tag appeared at
699 offsets near 8192 in the file being parsed. [Jeff Trawick]
701 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
702 reached. [Jeff Trawick]
704 *) Numerous improvements to the Win32 build system. Introduced command line
705 builds without requiring .mak files for MSVC 6.0 and later versions.
706 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
709 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
710 reporting of uninstalled services and other error conditions, and changed the
711 default service name to Apache2. [William Rowe]
713 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
714 compatibility with existing Apache 1.3 Win32 Apache management utilites.
715 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
717 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
718 [William Rowe, Greg Ames]
720 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
721 and RemoveCharset directives. [William Rowe]
723 *) The Unix MPMs other than perchild now allow child server
724 processes to use the accept mutex when starting as root and
725 using SysV sems for the accept mutex. Previously, this
726 combination would lead to fatal errors in the child server
727 processes. perchild can't use SysV sems because of security
728 issues. [Jeff Trawick, Greg Ames]
730 *) Added Win32 revision stamp resources to all http binaries
731 (including modules/ and support/ tools.) PR7322 [William Rowe]
733 *) Fix ap_rvprintf to support more than 4K of data at one time.
734 [Cody Sherr <csherr@covalent.net>]
736 *) We have always used the obsolete/deprecated Netscape syntax
737 for our tracking cookies; now the CookieStyle directive
738 allows the Webmaster to choose the Netscape, RFC2109, or
739 RFC2965 format. The new CookieDomain directive allows the
740 setting of the cookie's Domain= attribute, too. PR #s 5006,
741 5023, 5920, 6140 [Ken Coar]
743 *) Tweak server/Makefile so that the rules for generating exports.c
744 are compatible with make utilities which don't expand wildcards
745 in a dependency list (e.g., OS/390 make, certain levels of GNU
746 make). [Jeff Trawick]
748 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
750 *) Begin to sanitize the MPM configuration directives. Now, all
751 MPMs use the same functions for all common MPM directives. This
752 should make it easier to catch all bugs in these directives once.
753 [Cody Sherr <csherr@covalent.net>]
755 *) Close a major resource leak. Every time we had issued a
756 graceful restart, we leaked a socket descriptor.
759 *) Fix a problem with the new method code. We need to cast
760 the 1 to an apr_int64_t or it will be treated as a 32-bit
761 integer, and it will wrap after being shifted 32 times.
762 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
764 *) Fix a bug in mod_expires. Previous to this patch, if you
765 told mod_expires to add 604800 seconds to the last-modified
766 time, it actually added 604800 usec's to the last-modified time,
767 so that when looking at the response it looked like nothing
768 had been done. The root of the problem was that we always compute
769 time in usec's, but we ask users to input sec's. This means we
770 need to convert to usec's before using those values.
773 *) The worker MPM now handles shutdown and restart requests. It
774 definitely isn't perfect, but we do stop the servers correctly.
775 The biggest problem right now is that SIGHUP causes the server to
776 just die. [Ryan Bloom]
778 Changes with Apache 2.0.23
780 *) Use the prefork MPM by default on Unix. [various]
782 *) Added a systray icon monitor application for Win32.
783 [Mladen Turk <mturk@mappingsoft.com>]
785 *) mod_rewrite: Fix the line ending on some non-Unix systems for
786 messages written to the rewrite log.
787 [Richard Labennett <rlabenn@us.ibm.com>]
789 *) All mod_autoindex query parsing is now quietly quashed with the
790 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
791 still drops the column sort <a href>'s for the column headers, but
792 IgnoreClient is required to ignore these Query options entirely.
795 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
796 to allow the client to select plain, FancyIndexing or HTMLTable
797 formatting, V=[0|1] to inhibit or enable version sorting, and
798 P=pattern to return only specific files. The old Query Arguments
799 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
800 as before), and O=A|D for ordering ascending or descending.
803 *) Fixed an error in mod_include's directive parsing routines which
804 caused #if, #elif, and #else expressions containing backslashes
805 to be improperly evaluated. [Cliff Woolley]
807 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
808 drop the icon column, SuppressRules to drop the <hr> elements,
809 and HTMLTable to create rudimentary HTML table listings (implies
810 FancyIndexing). [William Rowe]
812 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
813 from Apache 1.3.15. This is needed for two reasons, first, given
814 multiple machines within a server farm, ETags and Last-Modified
815 stamps won't correspond from machine to machine, and second, many
816 Unixes don't capture changes to the date or time stamp of existing
817 files, since these don't modify the dirent itself. [William Rowe]
819 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
820 and DirectoryWidth options from Apache 1.3.10.
821 [William Rowe, Ken Coar]
823 *) Eliminated FancyIndexing directive, deprecated early in Apache
824 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
826 *) mod_autoindex now excludes any file names that would result in
827 an error, other than a success or redirect. Also optimized
828 the parent directory, always included except in the URI '/'.
831 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
832 negotiated index pages, and prevent the server from defaulting
833 to an autoindex of the directory. mod_negotiation will now die
834 with a 500 Internal Error if it could match some filenames
835 (e.g. for mod_dir) but none can be served. mod_negotation now
836 refuses to serve any file with an extention that mod_mime doesn't
837 recognize, and wasn't part of the request. [William Rowe]
839 *) Eliminate mod_cgi's handling of .exe files without the .exe file
840 extension. This is already handled by multiviews, if the admin
841 wishes to AddHandler .exe or define a content type handler and
842 associate .exe files with that content type. Multiviews must be
843 enabled to allow these to be served. [William Rowe]
845 *) Speed up the server's response to a spike in incoming workload
846 or restarts by assigning empty scoreboard slots to new processes
847 when they are available. [Greg Ames]
849 *) Add a handler to mod_includes.c. This handler is designed to
850 implement the XbitHack directive. This can't be done with a
851 fixup, because we need to check the content-type, which is
852 only available in the handler phase. [Ryan Bloom]
854 *) Make the includes filter check return codes from filters lower in
855 the filter chain. If a lower level filter returns an error, then
856 the request needs to stop immediately. This allows mod_include to
857 stop parsing data once a lower filter recognizes an error.
860 *) Add the ability to extend the methods that Apache understands
861 and have those methods <limit>able in the httpd.conf. It uses
862 the same bit mask/shifted offset as the original HTTP methods
863 such as M_GET or M_POST, but expands the total bits from an int to
864 an ap_int64_t to handle more bits for new request methods than
865 an int provides. [Cody Sherr <csherr@covalent.net>]
867 *) Fix broken mod_mime behavior in merging its arguments. Possible
868 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
870 *) Solve many mod_ssl porting issues (too many to detail) with
871 help from the whole team, but most notably [Ralf S. Engelschall,
872 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
873 Doug MacEachern, William Rowe, Cliff Woolley]
875 *) More stall fixes for the threaded & worker mpm's.
876 Make mod_status output more accurate. Don't
877 count workers in processes which aren't actively
878 serving requests. [Greg Ames]
880 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
882 *) Add a single listener/multiple worker MPM. This MPM is
883 definately not fully correct, but it allows us to solve many
884 of the problems that exist in the threaded MPM. This is a
885 modified version of the threaded MPM. [Ryan Bloom]
887 *) Improve content generation throughout Apache, providing closer
888 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
889 Transitional specifications. [William Rowe]
891 Changes with Apache 2.0.22
893 *) Fix a problem where the threaded MPM stalls after restarts or
894 segfaults. Also prevent multiple active processes from using
895 the same scoreboard slot. [Greg Ames]
897 *) Apache/Win32 now fills in the service description with Apache's
898 server version string, including loaded and advertised modules.
901 *) Improved support for the Win32 build, to recover gracefully from
902 missing apr or apr-util directories or the awk interpreter,
903 create the proper cgi-bin examples, including a test-cgi.bat, and
904 fix the perl shebang line for printenv.pl, when installing from
905 the build environment. [William Rowe]
907 *) Fix a segfault in threaded.c caused by passing uninitialized
908 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
910 *) Use new APR number conversion functions to reduce CPU consumption
911 when setting the content length, and in mod_log_config.
914 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
915 where HEAD response headers were being repeated twice for
916 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
917 problem in the http_header filter was exposed by the recent rewrite
918 of the content_length filter. [Taketo Kabe, Bill Stoddard]
920 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
921 restarts. A garbage pointer to a vhost's server_rec from the
922 previous generation was being left around under certain
923 conditions. [Greg Ames]
925 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
926 used to appear as '(none', without the closing paren.
927 [Günter Knauf <eflash@gmx.net>]
929 *) Improve the exports generating awk script. In the past, we had
930 work around problems in the awk script by avoiding some #if and
931 #ifdefs. This has bitten us many times in generating the exports.c
932 file. This improvement allows corrects the header file parsing.
933 [Sander Striker <striker@apache.org>]
935 Changes with Apache 2.0.21
937 *) Resolve the Win32 htpasswd bug, where a file that existed would be
938 overwritten, regardless of the -c flag.
939 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
941 *) Introduce connection sub-pools into ab. Truncating the lifetime
942 of these allocations means that ab no longer perpetually grows
943 its working set, running out of memory on large request attempts.
946 *) Make scoreboard creation a hook. This allows management
947 modules to have access to the scoreboard at the time that it is
948 created, and at every restart request.
949 [Cody Sherr <csherr@covalent.net>]
951 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
952 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
953 daemon index actually used in the scoreboard. I also
954 updated the pertinent calls. [Paul J. Reder]
956 *) Win32: Prevent listening sockets from being inherited by
957 the Apache child process, CGI scripts, rotatelog process
958 etc. If the Apache child process segfaults, any processes
959 that the child started are not reaped. Prior to this fix,
960 these processes inherited the listening sockets which sometimes
961 prevented the restarted Apache child process from accepting
962 connections (ie, the server would hang).
965 *) Provide vhost and request strings when ExtendedStatus is on.
968 *) Fix some issues with the pod and prefork: check the pod *after*
969 processing a connection so that a server processing a time-
970 consuming request bails out as soon as practical; when the
971 parent process wakes up a server process via connect(), use an
972 APR timeout on the connect() so that we don't hang for a long
973 time if there aren't server processes around to do accept().
974 [Jeff Trawick, Greg Ames]
976 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
977 spends a lot of time in apr_table_get calls. Using the default
978 httpd.conf, the tables for languages and charsets are somewhat
979 large, so the time spent scanning them on each request is
980 significant. Replacing the tables with hash tables provides
981 a nice speedup. [Brian Pane <bpane@pacbell.net>]
983 *) Add two functions to allow modules to access random parts of the
984 scoreboard. This allows modules compiled for one MPM to access the
985 scoreboard, even if it the server was compiled for another MPM.
986 [Harrie Hazewinkel <harrie@covalent.net>]
988 Changes with Apache 2.0.20
990 *) Fix problem in content-length filter where the filter would
991 buffer all the output from a CGI before sending any bytes
992 down the filter stack to the network. This problem would cause
993 significant memory consumption if the CGIs generated
994 lots of bytes. [Bill Stoddard]
996 *) Get non-blocking CGI pipe reads working with the bucket brigades.
999 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
1002 *) Fix a bug in the threaded MPM that would cause it to kill off all
1003 workers immediately after starting if the number of workers started
1004 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
1006 Changes with Apache 2.0.19
1008 *) Fix problem with threaded MPM. The problem was that if each child
1009 process was busy serving a single long-lived request and the server
1010 was sent a graceful restart signal, the server would stop serving
1011 requests. This would happen because each child process would wait to
1012 die until the last thread was done, and the parent wouldn't spawn any
1013 new children until a process died. Now, the parent looks at the fact
1014 that the children are dying gracefully, and starts new children.
1015 Those new children only start enough threads to compliment the number
1016 of threads in the other child process that shares the same spot in
1017 the scoreboard. In this way, we make sure to never go over
1018 MaxClients. [Ryan Bloom]
1020 *) modified mod_negotiation and mod_autoindex to speed up by almost a
1021 factor of two on apr_dir_read()-enhanced platforms, such as Win32
1022 and OS2, by calling ap_sub_request_lookup_dirent() with the results
1023 already provided by apr_dir_read(). [William Rowe]
1025 *) mod_file_cache is now more robust to filtering and serves requests
1026 slightly more efficiently. [Cliff Woolley]
1028 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
1029 Module was calling ap_rwrite() followed by ap_rflush() but the
1030 served content was not being displayed in the browser. Inspection
1031 of the output stream revealed that the first data chunk was
1032 missing the trailing CRLF required by the RFC. [Bill Stoddard]
1034 *) apxs no longer generates ap_send_http_header() in the example handler
1036 *) Fix an ab problem which could cause a divide-by-zero exception
1037 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
1038 [Ian Holsman <ianh@cnet.com>]
1040 *) Solve case-insensitive platforms' confusion about negotiated
1041 filenames, allowing files of differnt case to match in choosing
1042 the document to serve. [William Rowe]
1044 *) Fix brokenness when ThreadsPerChild is higher than the built-in
1045 limit. We left ap_threads_per_child at the higher value which
1046 led to segfaults when doing certain scoreboard operations.
1049 *) Fix seg faults and/or missing output from mod_include. The
1050 default_handler was using the subrequest pool for files and
1051 MMAPs, even though the associated APR structures typically
1052 live longer than the subrequest. [Greg Ames]
1054 *) Extend mod_setenvif to support specifying regular expressions
1055 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
1056 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
1057 will cause HAVE_TS to be set if any of the request headers begins
1058 with "TS" and has a value that begins with any character in the
1059 set [a-z]. [Bill Stoddard]
1061 *) httpd children now re-bind themselves to a random CPU on
1062 multiprocessor systems on AIX via bindprocessor() in 2.0.
1063 [Victor J. Orlikowski]
1065 *) Fix htdigest. It would go into a loop in getline when adding
1066 a second user. [Bill Stoddard]
1068 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
1070 *) Automatically generate httpd.exp for AIX.
1071 DSOs now work again on AIX in 2.0
1072 [Victor J. Orlikowski]
1074 *) Add a new request hook, error_log. This phase allows modules
1075 to act on the error log string _after_ it has been written
1076 to the error log. The goal for this hook is to allow monitoring
1077 modules to send the error string to the monitoring agent.
1080 *) Modify mod_echo to make it use filters for input and output.
1081 [Ryan Morgan <rmorgan@covalent.net>]
1083 *) Extend mod_headers to support conditional driven Header
1084 add, append and set. Use SetEnvIf to set an envar and conditionally
1085 add/append/set headers based on this envar thusly:
1087 SetEnvIf TSMyHeader value HAVE_TSMyHeader
1088 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
1090 If the request contains header "TSMyHeader: value" then header
1091 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
1094 *) Extend mod_headers to support using format specifiers on Header
1095 add, append and set header values. Two format specifiers are supported:
1097 %t - reports, in UTC microseconds since the epoch, when the
1098 request was received.
1100 %D - reports the time, in microseconds, between when the request was
1101 received and the response sent.
1104 Header add MyHeader "This request served in %D microseconds. %t"
1106 results in a header being added to the response that looks like this:
1108 MyHeader: This request served in D=5438 microseconds. t=991424704447256
1112 *) Fix reset_filter(). We need to be careful how we remove filters.
1113 If we set r->output_filters to NULL, we also have to reset the
1114 connection's filters. [John Sterling]
1116 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
1118 *) Add a check to ap_die() to make sure the filter stack is sane and
1119 contains the correct basic filters when an error occurs. This fixes
1120 a problem where headers are not being sent on error. [John Sterling]
1122 *) New Header directive 'echo' option. "Header echo regex" will
1123 cause any headers received on the request that match regex to be
1124 echoed to (included in) the response headers.
1127 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
1128 This prevented the inclusion of apr_compat.h. PR #7773
1129 [Oleg Broytmann <phd@phd.pp.ru>]
1131 *) Moved util_uri to the apr-util library. This required a bunch of
1132 apr_name changes for the uri utility functions. [Justin Erenkrantz]
1134 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
1135 insert_filter phase so that other filters are not bypassed by default.
1138 *) Reimplement mod_headers as an output filter. mod_headers can now
1139 add custom headers to inbound requests using the RequestHeader directive
1140 and to responses using the same old Header directive. [Graham Leggett]
1142 Changes with Apache 2.0.18
1144 *) Fix command-line processing so that if a bad argument is specified
1145 Apache will exit. [Jeff Trawick]
1147 *) Change the make targets and rules to be consistent in all of the
1148 Apache-owned source trees. [Roy Fielding]
1150 *) Fix processing of the TRACE method. Previously we passed bogus
1151 parms to form_header_field() and it overlaid some vhost structures,
1152 resulting in a segfault in check_hostalias().
1153 [Greg Ames, Jeff Trawick]
1155 *) Win32: Add support for reliable piped logs. If the logging process
1156 goes down, Apache will automatically restart it. This function has
1157 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
1160 *) Do not start piped log processes during the config file
1161 preflight. This change also circumvents a problem on
1162 Windows where the rotatelog processes created during preflight
1163 was not getting cleaned up properly.
1166 *) add "Request Phase Participation" info to mod_info
1169 *) Make first phase changes to the scoreboard data structures in
1170 preparation for the rewriting of the scoreboard per my posted
1171 design notes. [Paul J. Reder]
1173 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
1174 and apr-util, allow it to be overridden by the configure command-line
1175 (default="--silent") and introduce LT_LDFLAGS to replace what we were
1176 formerly abusing as LTFLAGS. [Roy Fielding]
1178 *) Clean up the reporting of incorrect closing container tags.
1179 [Barrie Slaymaker <barries@slaysys.com>]
1181 *) Simplify the configure process by moving all libtool stuff to APR
1182 and moving hints.m4 inline. [Roy Fielding]
1184 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
1185 of functions used by mod_proxy for export in the DLL
1186 [Ian Holsman <IanH@cnet.com>]
1188 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
1189 request body from its stdin but no reqest body is being written to
1190 the cgi. [Jeff Trawick]
1192 *) mod_log_config: %c connection status incorrectly logged
1193 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
1196 *) Get mod_cern_meta working under Windows
1199 *) Create Files, and thus MMAPs, out of the request pool, not the
1200 connection pool. This solves a small resource leak that had us
1201 not closing files until a connection was closed. In order to do
1202 this, at the end of the core_output_filter, we loop through the
1203 brigade and convert any data we have into a single HEAP bucket
1204 that we know will survive clearing the request_rec.
1205 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
1208 *) Completely revamp configure so that it preserves the standard make
1209 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
1210 the configure additions to EXTRA_* variables. Also, allow the user
1211 to specify NOTEST_* values for all of the above, which eliminates the
1212 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
1213 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1214 avoid pointless duplications. Fix the order in which flags are given
1215 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1216 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1217 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1218 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1220 *) Get mod_tls to compile/work better on Windows. PR #7612
1221 [Bernhard Schrenk <b.schrenk@improx.com>]
1223 *) Fix shutdown/restart hangs in the threaded MPM.
1224 [Jeff Trawick, Greg Ames, Ryan Bloom]
1226 *) Removed the keptalive boolean from conn_rec because it is now only
1227 used by a single routine and can be replaced by a local variable.
1228 [Greg Stein, Ryan Bloom, Roy Fielding]
1230 *) Patch prefork to put enough of the signal processing back in so that
1231 signals are all handled properly now. The previous patch fixed the
1232 deadlock race condition, but broke the user directed signal handling.
1233 This fixes it to work the way it did before my previous prefork patch
1234 (primarily, SIGTERM is now working).
1236 *) Change how input filters decide how much data is returned to the
1237 higher filter. We used to use a field in the conn_rec, with this
1238 change, we use an argument to ap_get_brigade to determine how much
1239 data is retrieved. [Ryan Bloom]
1241 *) Fix seg fault at start-up introduced by Ryan's change to enable
1242 modules to specify their own logging tags. mod_log_config
1243 registers an optional function, ap_register_log_handler().
1244 ap_register_log_handler() was being called by http_core before
1245 the directive hash table was created. This patch creates the
1246 directive hash table before ap_register_log_handler() is
1247 registered as an optional function.
1248 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1250 *) Add ap_set_int_slot() function
1251 [John K. Sterling <sterling@covalent.net>]
1253 *) Under certain circumstances, Apache did not supply the
1254 right response headers when requiring authentication.
1255 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1256 (This is a port of the change that went into Apache 1.3.19.)
1258 *) Allow modules to specify their own logging tags. This basically
1259 allows a module to tell mod_log_config that when %x is encountered
1260 a specific function should be called. Currently, x can be any single
1261 character. It may be more useful to make this a string at some point.
1264 Changes with Apache 2.0.17
1266 *) If a higher-level filter handles the the byterange aspects of a
1267 request, then the byterange filter should not try to redo the
1268 work. The most common case of this happening, is a byterange
1269 request going through the proxy, and the origin server handles
1270 the byterange request. The proxy should ignore it.
1271 [Graham Leggett <minfrin@sharp.fm>]
1273 *) Changed the threaded mpm to have child_main join to each of the
1274 worker threads to make sure the kids are all gone before child_main
1275 exits after a signal (cleanup from perform_idle_server_maintenance).
1276 This is an extension of Ryans recent commit to make the child_main
1279 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1280 report if their threads are dynamic or static. Finally, this also
1281 implements a new API, ap_show_mpm, which returns the MPM that was
1282 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1284 *) Do not install the binaries from the support directory twice.
1285 [jun-ichiro hagino <itojun@iijlab.net>]
1287 *) The ap_f* functions should flush data to the filter that is passed
1288 in, not the the filter after the one passed in.
1289 [Ryan Morgan <rmorgan@covalent.net>]
1291 *) Make ab work again by changing its native types to apr types and formats.
1292 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1294 *) Move the byterange filter and all of the supporting functions back
1295 to the HTTP module. The byterange filter turned out to be very
1296 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1298 *) Make clean, distclean, and extraclean consistently according to the
1299 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1301 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1302 This may have been causing problems stopping processes in the threaded
1305 *) Fix content-length in mod_negotiation to a long int representation.
1308 *) Remove BindAddress from the default config file.
1309 [giles@nemeton.com.au]
1311 *) Allow module authors to add a module to their Apache build using
1312 --with-module, without re-running buildconf. The syntax is:
1313 --with-module=module_type:/path/to/module.c
1314 The configure script will copy the module.c file to
1315 modules/module_type, and it will be added to the relevant Makefiles.
1316 currently, this only works for static modules. [Ryan Bloom]
1318 *) Changes required to make prefork clean up idle children properly.
1319 There was a window during which a starting worker deadlocks when
1320 an idle cleanup arrives before it completes init. Apache then keeps
1321 trying to cleanup the same deadlocked worker forever (until higher
1322 pids come along, but it still will never reduce below the deadlocked
1323 pid). Thus the number of children would not reduce to the correct
1324 idle level. [Paul J. Reder]
1326 Changes with Apache 2.0.16
1328 *) Change the default installation directory to /usr/local/apache2,
1329 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1331 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1334 *) Get MaxRequestsPerChild working with the Windows MPM.
1337 *) Make generic hooks to work, with mod_generic_hook_import/export
1338 experimental modules. [Ben Laurie, Will Rowe]
1340 *) Fix segfaults for configuration file syntax errors such as
1341 "<Directory>" followed by "</Directory" and
1342 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1344 *) Cleanup the --enable-layout option of configure. This makes
1345 us use a consistent location for the config.layout file, and it
1346 makes configure more portable.
1347 [jun-ichiro hagino <itojun@iijlab.net>]
1349 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1350 csv/gnuplot format, rudimentary ssl support and various other tweaks
1351 to make results more true to what is measured. The upshot of this it
1352 turns out that 'ab' has often underreported the true performance of
1353 apache. Often by a order of magnitude :-) See talk/paper of Sander
1354 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1355 [Dirk-Willem van Gulik]
1357 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1358 storage leak this ensures that some unnecessary pipes are closed.
1361 *) Performance: Add quick_handler hook. This hook is called at the
1362 very beginning of the request processing before location_walk,
1363 translate_name, etc. This hook is useful for URI keyed content
1364 caches like Mike Abbott's Quick Shortcut Cache.
1367 *) top_module global variable renamed to ap_top_module [Perl]
1369 *) Move ap_set_last_modified to the core. This is a potentially
1370 controversial change, because this is kind of HTTP specific. However
1371 many protocols should be able to take advantage of this kind of
1372 information. I expect that headers will need one more layer of
1373 indirection for multi-protocol work, but this is a small step in
1374 the right direction. [Ryan Bloom]
1376 *) Enable mod_status by default. This matches what Apache 1.3 does.
1379 *) Add a ScriptSock directive to the default config file. This is
1380 only enabled when mod_cgid is used.
1381 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1383 Changes with Apache 2.0.15
1385 *) Untangled the buildconf script and eliminated the need for build's
1386 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1387 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1389 *) Win32: Don't accept more connections than we have worker threads
1393 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1394 to fork() new child processes.
1397 *) Fix a major security problem with double-reverse lookup checking.
1398 Previously, a client connecting over IPv4 would not be matched
1399 properly when the server had an IPv6 listening socket. PR #7407
1400 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1402 *) Change the way the beos MPM handles polling to allow it to stop and
1403 restart. Problem was the sockets being polled were being reset by
1404 the select call, so once it had accepted a connection it was no
1405 longer listening on the UDP socket we use for shutdown instructions.
1406 APR needs to be altered, patch on it's way. [David Reid]
1408 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1409 on error exit from ap_getline(). Some other code got upset because
1410 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1412 *) Handle ap_discard_request_body() being called more than once.
1413 [Greg Ames, Jeff Trawick]
1415 *) Get rid of an inadvertent close of file descriptor 2 in
1416 mod_mime_magic. [Greg Ames, Jeff Trawick]
1418 *) Add a hook, create_request. This hook allows modules to modify
1419 a request while it is being created. This hook is called for all
1420 request_rec's, main request, sub request, and internal redirect.
1421 When this hook is called, the the r->main, r->prev, r->next
1422 pointers have been set, so modules can determine what kind of
1423 request this is. [Ryan Bloom]
1425 *) Cleanup the build process a bit more. The Apache configure
1426 script no longer creates its own helper scripts, it just
1428 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1430 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1431 proxy requests. [Graham Leggett]
1433 *) Avoid using sscanf to determine the HTTP protocol number in
1434 the common case because sscanf is a performance hog. From
1435 Mike Abbot's Accelerating Apache patch number 6.
1436 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1438 *) Fix a security exposure in mod_access. Previously when IPv6
1439 listening sockets were used, allow/deny-from-IPv4-address rules
1440 were not evaluated properly (PR #7407). Also, add the ability to
1441 specify IPv6 address strings with optional prefix length on Allow
1442 and Deny. [Jeff Trawick]
1444 *) Enhance rotatelogs so that a UTC offset can be specified, and
1445 the logfile name can be formatted using strftime(3). (Brought
1446 forward from 1.3.) [Ken Coar]
1448 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1449 DuplicateHandle on an IOCompletionPort (a practice which
1450 MS "discourages"). The new model does not rely on associating
1451 the completion port with the listening sockets, thus the
1452 completion port can be completely managed within the child
1453 process. A dedicated thread accepts connections off the network,
1454 then calls PostQueuedCompletionStatus() to wake up worker
1455 threads blocked on the completion port.
1458 *) Bring forward the --suexec-umask option which allows the
1459 builder to preset the umask for suexec processes. [Ken Coar]
1461 *) Add a -V flag to suexec, which causes it to display the
1462 compile-time settings with which it was built. (Only
1463 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1465 *) Mod_include should always unset the content-length if the file is
1466 going to be passed through send_parsed_content. There is no to
1467 determine if the content will change before actually scanning the
1468 entire content. It is far safer to just remove the C-L as long
1469 as we are scanning it. [Ryan Bloom]
1471 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1472 request and not Proxy-Authenticate.
1473 [Graham Leggett <minfrin@sharp.fm>]
1475 Changes with Apache 2.0.14
1477 *) Fix content-length computation. We ONLY compute a content-length if
1478 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1479 or we already have all the data. [Ryan Bloom]
1481 *) Report unbounded containers in the config file. Previously, a typo
1482 in the </container> directive could result in the rest of the config
1483 file being silently ignored, with undesired defaults used.
1486 *) Make the old_write filter use the ap_f* functions for the buffering.
1489 *) Move more code from the http module into the core server. This
1490 is core code, basically the default handler, the default input
1491 and output filters, and all of the core configuration directives.
1492 All of this code is required in order for the server to work, with or
1493 without HTTP. The server is closer to working without the HTTP
1494 module, although there is still more to do. [Ryan Bloom]
1496 *) Fix a number of SGI compile warnings throughout the server. Fix some
1497 bad parameters to apr_bucket_read(). Fix a bad statement in
1498 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1499 consistently; we were mixing apr_time_t and time_t in invalid ways
1500 before. In load_file(), call apr_dso_error() instead of
1501 apr_strerror() so that we get a more specific string on some platforms.
1502 PR #6980 [Jeff Trawick]
1504 *) Allow modules to query the MPM about it's execution profile. This
1505 query API can and should be extended in the future, but for now,
1506 max_daemons, and threading or forking is a very good start.
1507 [Jon Travis <jtravis@covalent.net>]
1509 *) Modify mod_include to send blocks of data no larger than 9k.
1510 Without this, mod_include will wait until the whole file is parsed,
1511 or the first tag is found to send any data to the client.
1512 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1514 *) Fix mod_info, so that <Directory> and <Location> directives are
1515 not displayed twice when displaying the current configuration.
1516 [Ryan Morgan <rmorgan@covalent.net>]
1518 *) Add config directives to override DEFAULT_ERROR_MSG and
1519 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1520 [Dan Rench <drench@xnet.com>]
1522 *) Get mod_info building and loading on Win32. [William Rowe]
1524 *) Begin to move protocol independant functions out of mod_http. The goal
1525 is to have only functions that are HTTP specific in the http directory.
1528 Changes with Apache 2.0.13
1530 *) Don't assume that there will always be multiple calls to the byterange
1531 filter. It is possible that we will need to do byteranges with only
1532 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1534 *) Move the error_bucket definition from the http module to the
1535 core server. Every protocol will need this ability, not just
1538 Changes with Apache 2.0.12
1540 *) Modify mod_file_cache to save pre-formatted strings for
1541 content-length and last-modified headers for performance.
1542 [Mike Abbot <mja@trudge.engr.sgi.com>]
1544 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1545 [Jon Travis <jtravis@covalent.net>]
1547 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1548 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1550 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1551 without ever filling it out. This fixes PR 7271.
1552 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1553 Cliff Woolley <cliffwoolley@yahoo.com>]
1555 *) Add a couple of GCC attribute tags to printf style functions.
1556 [Jon Travis <jtravis@covalent.net>]
1558 *) Add the correct language tag for interoperation with the Taiwanese
1559 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1561 *) Migrate the perchild MPM to use the new apr signal child, and
1562 APR thread functions. [Ryan Bloom]
1564 *) Close one copy of the CGI's stdout before creating the new process.
1565 The CGI will still have stdout, because we have already dup'ed it.
1566 This keeps Apache from waiting forever to send the results of a CGI
1567 process that has forked a long-lived child process.
1568 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1570 *) Remove the rest of the pthreads functions from the threaded MPM.
1571 This requires the APR support for a signal thread that was just
1574 *) Make mod_dir use a fixup for sending a redirect to the browser.
1575 Before this, we were using a handler, which doesn't make much
1576 sense, because the handler wasn't generating any data, it would
1577 either return a redirect error code, or DECLINED. This fits the
1578 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1580 *) Make the threaded MPM use APR threads instead of pthreads.
1583 *) Get mod_tls to the point where it actually appears to work in all cases.
1586 *) implement --enable-modules and --enable-mods-shared for "all" and
1587 "most". [Greg Stein]
1589 *) Move the threaded MPM to use APR locks instead of pthread locks.
1592 *) Rename mpmt_pthread to threaded. This is more in line with the
1593 fact that mpmt_pthread shouldn't be using pthreads directly, and
1594 it is a smaller name that doesn't tie into anything.
1597 *) Rename the module structures so that the exported symbol matches
1598 the file name, and it is easier to automate the installation
1599 process (generating LoadModule directives from the module filenames).
1602 *) Remove the coalesce filter. With the ap_f* functions, this filter
1603 is no longer needed. [Ryan Bloom]
1605 Changes with Apache 2.0.11
1607 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1608 added feature of allowing a uid/gid per child process. If no
1609 uid/gid is specified, then Perchild behaves exactly like dexter.
1612 *) Get perchild building again. [Ryan Bloom]
1614 *) Don't disable threads just because we are using the prefork MPM.
1615 If somebody wants to compile without threads, they must now add
1616 --disable-threads to the configure command line. [Ryan Bloom]
1618 *) Begin to move the calls to update_child_status into common code, so
1619 that each individual MPM does not need to update the scoreboard itself.
1622 *) Allow mod_tls to compile under Unix boxes where openssl has been
1623 installed to the system include files.
1624 [Gomez Henri <new-httpd@slib.fr>]
1626 *) Cleanup the mod_tls configure process. This should remove any need
1627 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1628 configure doesn't check that yet. [Ryan Bloom]
1630 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1631 vital that you read modules/tls/README before attempting to build
1634 *) Fix a potential seg fault on all platforms. David Reid fixed this
1635 on BEOS, but the problem could happen anywhere, so we don't want
1636 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1638 *) Add new LogFormat directive, %D, to log time it takes to serve a
1639 request in microseconds. [Bill Stoddard]
1641 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1642 SetOutputFilter. This corresponds nicely with the other Set
1643 directives, which operate on containers while the Add* directives
1644 tend to work directly on extensions. [Ryan Bloom]
1646 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1647 functions for the buffering so that we don't need to compute
1648 the length of the headers before we actually create the header
1649 buffer. [Ryan Bloom]
1651 *) Allow filters to buffer data using the ap_f* functions. These have
1652 become macros that resolve directly to apr_brigade_*.
1655 *) Get the Unix MPM's to do a graceful restart again. If we are going
1656 to register a cleanup with ap_cleanup_scoreboard, then we have to
1657 kill the cleanup with the same function, and that function can't be
1658 static. [Ryan Bloom]
1660 *) Install all required header files. Without these, it was not
1661 possible to compile some modules outside of the server.
1664 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1665 forward from 1.3 to 2.0, we missed a single line, which broke regex
1666 aliases. [Ryan Bloom]
1668 *) We have a poor abstraction in the protocol. This is a temporary
1669 hack to fix the bug, but it will need to be fixed for real. If
1670 we find an error while sending out a custom error response, we back
1671 up to the first non-OK request and send the data. Then, when we send
1672 the EOS from finalize_request_protocol, we go to the last request,
1673 to ensure that we aren't sending an EOS to a request that has already
1674 received one. Because the data is sent on a different request than
1675 the EOS, the error text never gets sent down the filter stack. This
1676 fixes the problem by finding the last request, and sending the data
1677 with that request. [Ryan Bloom]
1679 *) Make the server status page show the correct restart time, and
1680 thus the proper uptime. [Ryan Bloom]
1682 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1683 should reduce the amount of duplicate code that is required to
1684 create CGI processes.
1685 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1687 *) ap_new_connection() closes the socket and returns NULL if a socket
1688 call fails. Usually this is due to a connection which has been
1689 reset. [Jeff Trawick]
1691 *) Move the Apache version information out of httpd.h and into release.h.
1692 This is in preparation for the first tag with the new tag and release
1693 system. [Ryan Bloom]
1695 *) Begin restructuring scoreboard code to enable adding back in
1696 the ability to use IPC other than shared memory.
1697 Get mod_status working on Windows again. [Bill Stoddard]
1699 *) Make mod_status work with 2.0. This will work for prefork,
1700 mpmt_pthread, and dexter. [Ryan Bloom]
1702 *) Correct a typo in httpd.conf.
1703 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1705 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1707 *) Get the correct IP address if ServerName isn't set and we can't
1708 find a fully-qualified domain name at startup.
1709 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1711 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1713 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1714 'extra' stat's for user/group since they should never occur, and now
1715 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1716 volumes. [William Rowe]
1718 *) Adopt apr features to simplify mod_includes. This changes the
1719 behavior of the USER_NAME variable, unknown uid's are now reported
1720 as USER_NAME="<unknown>" rather than the old user#000 result.
1721 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1723 *) Adopt apr features for simplifing mod_userdir, and accept the new
1724 Win32/OS2 exceptions without hiccuping. [William Rowe]
1726 *) Replace configure --with-optim option by using and saving the
1727 environment variable OPTIM instead. This is needed because configure
1728 options do not support multiple flags separated by spaces.
1731 *) Fix some byterange handling. If we get a byte range that looks like
1732 "-999999" where that is past the end of the file, we should return
1733 a PARTIAL CONTENT status code, and return the whole file as one big
1734 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1736 *) Make the error bucket a real meta-data bucket. This means that the
1737 bucket length is 0, and a read returns NULL data. If one of these
1738 buckets is passed down after the headers are sent, this data will
1739 just be ignored. [Greg Stein]
1741 *) The prefork MPM wasn't killing child processes correctly if a restart
1742 signal was received while the process was serving a request. The child
1743 process would become the equivalent of a second parent process. If
1744 we break out of the accept loop, then we need to do die after cleaning
1745 up after ourselves. [Ryan Bloom]
1747 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1748 restarts. [Ryan Bloom]
1750 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1751 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1752 performing very expensive owner, group and permission lookups
1753 and allows the server to function until these apr_finfo_t fields
1754 are implemented under Win32. [William Rowe]
1756 *) Support for typedsafe optional functions - that is functions exported by
1757 optional modules, which, therefore, may or may not be present, depending
1758 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1759 for sample code. [Ben Laurie]
1761 *) filters can now report an HTTP error to the server. This is done
1762 by sending a brigade where the first bucket is an error_bucket.
1763 This bucket is a simple bucket that stores an HTTP error and
1764 a string. Currently the string is not used, but it may be needed
1765 to output an error log. The http_header_filter will find this
1766 bucket, and output the error text, and then return
1767 AP_FILTER_ERROR, which informs the server that the error web page
1768 has already been sent. [Ryan Bloom]
1770 *) If we get an error, then we should remove all filters except for
1771 those critical to serving a web page. This fixes a bug, where
1772 error pages were going through the byterange filter, even though
1773 that made no sense. [Ryan Bloom]
1775 *) Relax the syntax checking of Host: headers in order to support
1776 iDNS. PR#6635 [Tony Finch]
1778 *) Cleanup the byterange filter to use the apr_brigade_partition
1779 and apr_bucket_copy functions. This removes a lot of very messy
1780 code, and hopefully makes this filter more stable.
1783 *) Remove AddModule and ClearModuleList directives. Both of these
1784 directives were used to ensure that modules could be enabled
1785 in the correct order. That requirement is now gone, because
1786 we use hooks to ensure that modules are in the correct order.
1789 *) When SuExec is specified, we need to add it to the list of
1790 targets to be built. If we don't, then any changes to the
1791 configuration won't affect SuExec, unless 'make suexec' is
1792 specifically run. [Ryan Bloom]
1794 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1795 the APR_XTHREAD argument to open a file for consumption by
1796 parallel threads on win32. [William Rowe]
1798 *) Correct a bug in determining when we follow symlinks. The code
1799 expected a stat -1 result, not an apr_status_t positive error.
1800 Also check if the APR_FINFO_USER fields are valid before we
1801 follow the link. [William Rowe]
1803 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1804 mpm_common.c. These functions are only valid on some platforms,
1805 so they should not be in the main-line code. [Ryan Bloom]
1807 *) Remove ap_chdir_file(). This function is not thread-safe,
1808 and nobody is currently using it. [Ryan Bloom]
1810 *) Do not try to run make depend if there are no .c files in the
1811 current directory, doing so makes `make depend` fail.
1814 *) Update highperformance.conf to work with either prefork or
1815 pthreads mpms. [Greg Ames]
1817 *) Stop checking to see if this is a pipelined request if we know
1818 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1819 This keeps us from making an extra read call when serving a 1.0
1820 request. [Ryan Bloom and Greg Stein]
1822 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1823 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1824 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1826 *) Fix the RFC number mentioned when complaining about a missing
1827 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1829 *) Fix an endless loop in ab which occurred when ab was posting
1830 and the server dropped the connection unexpectedly.
1833 *) Fix a segfault while handling request bodies in ap_http_filter().
1834 This problem has been seen with mod_dav usage as well as with
1835 requests where the body was just being discarded. [Jeff Trawick]
1837 *) Some adjustment on the handling and automatic setting (via
1838 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1839 add the capability to specify flags (NOTEST_CFLAGS and
1840 NOTEST_LDFLAGS) which are used to compile Apache, but
1841 not used during the configuration process. Useful for
1842 flags like "-Werror". [Jim Jagielski]
1844 *) Stop using environment variables to force debug mode or
1845 no detach. We now use the -D command line argument to
1846 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1847 [Greg Stein, Ryan Bloom]
1849 *) Change handlers to use hooks. [Ben Laurie]
1851 *) Stop returning copies of filenames from both apr_file_t and
1852 apr_dir_t. We pstrdup the filenames that we store in the
1853 actual structures, so we don't need to pstrdup the strings again.
1856 *) mod_cgi: Fix some problems where the wrong error value was being
1857 traced. [Jeff Trawick]
1859 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1862 *) Add generic hooks. [Ben Laurie]
1864 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1866 *) Fix a segfault caused by mod_ext_filter when the external filter
1867 program does not exist. [Jeff Trawick]
1869 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1870 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1871 was served through mod_charset_lite (or anything else that would
1872 create a transient bucket in this size range). ap_bucket_make_heap()
1873 silently failed (fixed), transient_setaside() discovered it, but
1874 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1876 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1877 is that some browsers send extra lines at the end of POST requests, and
1878 we don't want to delay sending data back to the user just because the
1879 browser isn't well behaved. [Ryan Bloom]
1881 *) Get SuEXEC working again. We can't send absolute paths to suExec
1882 because it refuses to execute those programs. SuEXEC also wasn't
1883 always recognizing configuration changes made using the autoconf
1886 *) Allow the buildconf process to find the config.m4 files in the correct
1887 order. Basically, we can now name config.m4 files as config\d\d.m4,
1888 and we will sort them correctly when inserting them into the build
1889 process. [Ryan Bloom]
1891 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1892 This also allows mod_cgid to use ap_os_create_priviledged_process,
1893 thus allowing for SuExec execution from mod_cgid. Currently, we do
1894 not support everything that standard SuExec supports, but at least
1895 it works minimally now. [Ryan Bloom]
1897 *) Allow SuExec to be configured from the ./configure command line.
1900 *) Update some of the docs in README and INSTALL to reflect some of
1901 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1903 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1904 need to call sendfile again. This gets us serving large files
1905 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1907 *) Get the support programs building cleanly again.
1908 [Cliff Woolley <cliffwoolley@yahoo.com>]
1910 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1911 current directory logic now backs up over bin/ to determine the
1912 server root from the Apache.exe path.
1914 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1915 loadable modules, dynamic libs are all named libfoo.dll, and the
1916 makefile.win populates the include, lib and libexec directories.
1918 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1919 Apache gets IPv6 listening sockets by default. Additionally, the
1920 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1921 numeric address strings (e.g., "Listen [fe80::1]:8080").
1924 *) Modify the install directory layout. Modules are now installed in
1925 modules/. Shared libraries should be installed in libraries/, but
1926 we don't have any of those on Unix yet. All install directories
1927 are modifyable at configure time. [Ryan Bloom]
1929 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1931 *) Get the functions in server/linked into the server, regardless of
1932 which modules linked into the server. This uses the same hack
1933 for Apache that we use for APR and apr-util to ensure all of the
1934 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1935 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1936 the scripts a bit easier.
1939 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1940 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1942 *) Get all of the auth modules to the point that they will install and
1943 be loadable into the server. Our new build/install mechanism expects
1944 that all modules will have a common name format. The auth modules
1945 didn't use that format, so we didn't install them properly.
1948 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1949 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1951 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1953 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1954 after the end of the response. [Ryan Bloom]
1956 *) Get byterange requests working with responses that do not have a
1957 content-length. Because of the way byterange requests work, we have to
1958 have all of the data before we can actually do the byterange, so we
1959 can compute the content-length in the byterange filter.
1962 *) Get exe CGI's working again on Windows.
1965 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1966 they keep track of whether or not their post config hook has been
1967 called before. Instead of a static variable (which is replaced when
1968 the DSO is loaded a second time), use userdata in the process pool.
1971 Changes with Apache 2.0a9
1973 *) Win32 now requires perl to complete the final install step for users
1974 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1975 and installs the conf, htdocs and htdocs/manual directories.
1978 *) Make mod_include use a hash table to associate directive tags with
1979 functions. This allows modules to implement their own SSI tags easily.
1980 The idea is simple enough, a module can insert it's own tag and function
1981 combination into a hash table provided by mod_include. While mod_include
1982 parses an SSI file, when it encounters a tag in the file, it does a
1983 hash lookup to find the function that implements that tag, and passes
1984 all of the relevant data to the function. That function is then
1985 responsible for processing the tag and handing the remaining data back
1986 to mod_include for further processing.
1987 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1989 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1990 fewer parameters: the local and remote socket addresses were removed
1991 from the parameter list because all required information is available
1992 via the APR socket. [Jeff Trawick]
1994 *) Distribution directory structure reorganized to reflect a
1995 normal source distribution with external install targets.
1998 *) The MPMs that need multiple segments of shared memory now create
1999 two apr_shmem_t variables, one for each shared memory allocation.
2000 the problem is that we can't determine how much memory will be required
2001 for shared memory allocations once we try to allocate more than one
2002 variable. The MM code automatically aligns the shared memory allocations,
2003 so we end up needing to pad the amount of shared memory we want based
2004 on how many variables will be allocated out of the shared memory segment.
2005 It is just easier to create a second apr_shmem_t variable, and two
2006 shmem memory blocks.
2009 *) Cleanup the export list a bit. This creates a single unified list of
2010 functions exported by APR. The export list is generated at configure
2011 time, and that list is then used to generate the exports.c file.
2012 Because of the way the export list is generated, we only export those
2013 functions that are valid on the platform we are building on.
2016 *) Enable logging the cookie with mod_log_config
2017 [Sander van Zoest <sander@covalent.net>]
2019 *) Fix a segfault in mod_info when it reaches the end of the configuration.
2022 *) Added lib/aputil/ as a placeholder for utility functions which are not
2023 specific to the Apache HTTP Server (but do not make sense with APR).
2024 The first utility is "apu_dbm": a set of functions to work with DBM
2025 files. This first version can be compiled for SDBM or GDBM databases.
2028 *) Complete re-write of mod_include. This makes mod_include a filter that
2029 uses buckets directly. This has now served the FAQ correctly.
2030 [Paul Reder <rederpj@raleigh.ibm.com>]
2032 *) Allow modules to specify the first filter in a sub_request when
2033 making the sub_request. This keeps modules from having to change the
2034 output_filter immediately after creating the sub-request, and therefore
2035 skip the sub_req_output_filter. [Ryan Bloom]
2037 *) Update ab to accept URLs with IPv6 literal address strings (in the
2038 format described in RFC 2732), and to build Host header fields in
2039 the same format. This allows IPv6 literal address strings to be
2040 used with ab. This support has been tested against Apache 1.3 with
2041 the KAME patch, but Apache 2.0 does not yet work with this format
2042 of the Host header field. [Jeff Trawick]
2044 *) Accomodate an out-of-space condition in the piped logs and the
2045 rotatelogs.c code, and no longer churn log processes for this
2046 condition. [Victor J. Orlikowski]
2048 *) Add support for partial writes with apr_sendfile() to core_output_filter.
2051 Changes with Apache 2.0a8
2053 *) Add a directive to mod_mime so that filters can be associated with
2057 *) Get multi-views working again. We were setting the path_info
2058 field incorrectly if we couldn't find the specified file.
2061 *) Fix 304 processing. The core should never try to send the headers
2062 down the filter stack. Always, just setup the table in the request
2063 record, and let the header filter convert it to data that is ready
2067 *) More fixes for the proxy. There are still bugs in the proxy code,
2068 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
2072 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
2075 *) APR: Add new apr_getopt_long function to handle long options.
2076 [B. W. Fitzpatrick <fitz@red-bean.com>]
2078 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
2079 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
2080 hostname resolution/address string parsing and building
2081 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
2082 of one of the apr_sockaddr_t structures for a socket. Change
2083 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
2085 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
2086 I have proxied pages with it, cleanup will commence soon.
2089 *) Make the proxy work with filters. This isn't perfect, because we
2090 aren't dealing with the headers properly. [Ryan Bloom]
2092 *) Do not send a content-length iff the C-L is 0 and this is a head
2093 request. [Ryan Bloom]
2095 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
2096 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
2098 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
2100 *) Get the default_handler to stop trying to deal with HEAD requests.
2101 The idea is to let the content-length filter compute the C-L before
2102 we try to send the data. If we can get the C-L correctly, then we
2103 should send it in the HEAD response.
2106 *) The Header filter can now determine if a body should be sent based
2107 on r->header_only. The general idea of this is that if we delay
2108 deciding to send the body, then we might be able to compute the
2109 content-length correctly, which will help caching proxies to cache
2110 our data better. Any handler that doesn't want to try to compute
2111 the content-length can just send an EOS bucket without data and
2112 everything will just work.
2115 *) Add the referer to the error log if one is available.
2116 [Markus Gyger <mgyger@itr.ch>]
2118 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
2119 change, the root of the configuration tree has been exposed to modules
2121 [Ryan Morgan <rmorgan@covalent.net>]
2123 *) Get the core_output_filter to use the bucket interface directly.
2124 This keeps us from calling the content-length filter multiple times
2125 for a simple static request.
2128 *) We are sending the content-type correctly now.
2129 [Ryan Bloom and Will Rowe]
2131 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
2132 a bogus bytes-sent value when the only thing being sent was trailers
2133 and writev() returned an error (or EAGAIN). [Jeff Trawick]
2135 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
2136 hints file to determine which platforms define
2137 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2140 *) APR: add apr_get_home_directory() [Jeff Trawick]
2142 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
2144 *) Not all platforms have INADDR_NONE defined by default. Apache
2145 used to make this check and define INADDR_NONE if appropriate,
2146 but APR needs the check too, and I suspect other applications will
2147 as well. APR now defines APR_INADDR_NONE, which is always a valid
2148 value on all platforms.
2149 [Branko Èibej <brane@xbc.nu>]
2151 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
2152 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
2154 *) Relax the syntax checking of Host: headers in order to support
2155 iDNS. PR#6635 [Tony Finch]
2157 *) When reading from file buckets we convert to an MMAP if it makes
2158 sense. This also simplifies the default handler because the
2159 default handler no longer needs to try to create MMAPs.
2162 *) BUFF has been removed from the main server. The BUFF code will remain
2163 in the code until it has been purged from the proxy module as well.
2166 *) Byteranges have been completely re-written to be a filter. This
2167 has been tested, and I believe it is working correctly, but it could
2168 doesn't work for the Adobe Acrobat plug-in. The output almost matches
2169 the output from 1.3, the only difference being that 1.3 includes
2170 a content-length in the response, and this does not.
2173 *) APR read/write functions and bucket read functions now operate
2174 on unsigned integers, instead of signed ones. It doesn't make
2175 any sense to use signed ints, because we return the error codes,
2176 so if we have an error we should report 0 bytes read or written.
2179 *) Always compute the content length, whether it is sent or not.
2180 The reason for this, is that it allows us to correctly report
2181 the bytes_sent when logging the request. This also simplifies
2182 content-length filter a bit, and fixes the actual byte-reporing
2183 code in mod_log_config.c
2186 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
2187 it says, because it was only used by EOS and FLUSH buckets. Since
2188 neither of those are required at the end of a brigade, this was
2189 really signifying FLUSH_THE_DATA, but that can be determined better
2190 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
2191 buckets now return a length of 0, which is actually the amount of data
2192 read, so they make more sense.
2195 *) Allow the core_output_filter to save some data past the end of a
2196 request. If we get an EOS bucket, we only send the data if it
2197 makes sense to send it. This allows us to pipeline request
2198 responses. As a part of this, we also need to allocate mmap
2199 buckets out of the connection pool, not the request pool. This
2200 allows the mmap to outlive the request.
2203 *) Make blocking and non-blocking bucket reads work correctly for
2204 sockets and pipes. These are the only bucket types that should
2205 have non-blocking reads, because the other bucket types should
2206 ALWAYS be able to return something immediately.
2209 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
2210 server, but use Ctrl+Break to initiate a graceful restart
2211 instead of duplicating behavior. [John Sterling]
2213 *) Patch mod_autoindex to set the Last-Modified header based on
2214 the directory's mtime, and add the ETag header. [William Rowe]
2216 *) Merge the 1.3 patch to add support for logging query string in
2217 such a way that "%m %U%q %H" is the same as "%r".
2220 *) Port three log methods from mod_log_config 1.3 to 2.0:
2221 CLF compliant '-' byte count, method and protocol.
2224 *) Add a new LogFormat directive, %c, that will log connection
2225 status at the end of the response as follows:
2226 'X' - connection aborted before the response completed.
2227 '+' - connection may be kept-alive by the server.
2228 '-' - connection will be closed by the server.
2231 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2232 Unicode file names and paths for Win32, and tag the Content-Type
2233 from mod_autoindex to reflect that charset if the the feature
2234 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2236 *) Compute the content length (and add appropriate header field) for
2237 the response when no content length is available and we can't use
2238 chunked encoding. [Jeff Trawick]
2240 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2241 so that content input filters get dechunked data when using
2242 the default handler. Also removed REQUEST_CHUNKED_PASS.
2245 *) Add mod_ext_filter as an experimental module. This module allows
2246 the administrator to use external programs as filters. Currently,
2247 only filtering of output is supported. [Jeff Trawick]
2249 *) Most Apache functions work on EBCDIC machines again, as protocol
2250 data is now translated (again). [Jeff Trawick]
2252 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2253 the EBCDIC support. They are noops on ASCII machines, so this
2254 type of translation doesn't have to be surrounded by #ifdef
2255 CHARSET_EBCDIC. [Jeff Trawick]
2257 *) Fix mod_include. tag commands work again, and the server will
2258 send the FAQ again. This also allows mod_include to set aside
2259 buckets that include partial buckets.
2260 [Ryan Bloom and David Reid]
2262 *) Add suexec support back. [Manoj Kasichainula]
2264 *) Lingering close now uses the socket directly instead of using
2265 BUFF. This has been tested, but since all we can tell is that it
2266 doesn't fail, this needs to be really hacked on.
2269 *) Allow filters to modify headers and have those headers be sent to
2270 the client. The idea is that we have an http_header filter that
2271 actually sends the headers to the network. This removes the need
2272 for the BUFF to send headers.
2275 *) Charset translation: mod_charset_lite handles translation of
2276 request bodies. Get rid of the xlate version of ap_md5_digest()
2277 since we don't compute digests of filtered (e.g., translated)
2278 response bodies this way anymore. (Note that we don't do it at
2279 all at the present; somebody needs to write a filter to do so.)
2282 *) Input filters and ap_get_brigade() now have a input mode parameter
2283 (blocking, non-blocking, peek) instead of a length parameter.
2286 *) Update the mime.types file to the registered media types as
2287 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2290 *) Namespace protect some macros declared in ap_config.h
2293 *) Support HTTP header line folding with input filtering.
2296 *) Mod_include works again. This should still be re-written, but at
2297 least now we can serve an SHTML page again.
2300 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2301 to both the BUFF and the socket in the conn_rec. Functions that
2302 want to use the BUFF can, functions that want to use the socket,
2303 can. They point to the same place.
2306 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2307 [Tomas "Ögren" <stric@ing.umu.se>]
2309 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2310 associated pool goes away. (APR pipes on OS/2 were already had this
2311 logic.) This resolvs a fatal file descriptor leak with CGIs.
2314 *) The final line of the config file was not being read if there was
2315 no \n at the end of it. This was caused by apr_fgets returning
2316 APR_EOF even though we had read valid data. This is solved by
2317 making cfg_getline check the buff that was returned from apr_fgets.
2318 If apr_fgets return APR_EOF, but there was data in the buf, then we
2319 return the buf, otherwise we return NULL.
2322 *) Piped logs work again in the 2.0 series.
2325 *) Restore functionality broken by the mod_rewrite security fix:
2326 rewrite map lookup keys and default values are now expanded
2327 so that the lookup can depend on the requested URI etc.
2328 PR #6671 [Tony Finch]
2330 *) Tighten up the syntax checking of Host: headers to fix a
2331 security bug in some mass virtual hosting configurations
2332 that can allow a remote attacker to retrieve some files
2333 on the system that should be inaccessible. [Tony Finch]
2335 *) Add a pool bucket type. This bucket is used for data allocated out
2336 of a pool. If the pool is cleaned before the bucket is destroyed, then
2337 the data is converted to a heap bucket, allowing it to survive the
2341 *) Add a flush bucket. This allows modules to signal that the filters
2342 should all flush whatever data they currently have. There is no way
2343 to actually force them to do this, so if a filter ignores this bucket,
2344 that's life, but at least we can try with this.
2347 *) Add an output filter for sub-requests. This filter just strips the
2348 EOS bucket so that we don't confuse the main request's core output
2349 filter by sending multiple EOS buckets. This change also makes sub
2350 requests start to send EOS buckets when they are finished.
2353 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2354 makes ap_bucket_destroy a return void, which is okay because it
2355 used to always return APR_SUCCESS, and nobody ever checked its
2356 return value anyway.
2357 [Cliff Woolley <cliffwoolley@yahoo.com>]
2359 *) Remove the index into the bucket-type table from the buckets
2360 structure. This has now been replaced with a pointer to the
2361 bucket_type. Also add some macros to test the bucket-type.
2364 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2365 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2366 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2367 All _VAR_ flavors changes to _DATA to be absolutely clear.
2370 *) Add support for /, //, //servername and //server/sharename
2371 parsing of <Directory> blocks under Win32 and OS2.
2372 [Tim Costello, William Rowe, Brian Harvard]
2374 *) Remove the function pointers from the ap_bucket type. They have been
2375 replaced with a global table. Modules are allowed to register bucket
2376 types and use then use those buckets.
2379 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2380 once we finish writing the request body to the cgi child process;
2381 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2382 worked without this change (for reasons I don't understand), but large
2383 ones didn't. [Jeff Trawick]
2385 *) Remove file bucket specific information from the ap_bucket type.
2386 This has been moved to a file_bucket specific type that hangs off
2387 the data pointer in the ap_bucket type.
2390 *) Input filtering now has a third argument. This is the amount of data
2391 to read from lower filters. This argument can be -1, 0, or a positive
2392 number. -1 means give me all the data you have, I'll deal with it and
2393 let you know if I need more. 0 means give me one line and one line
2394 only. A positive number means I want no more than this much data.
2396 Currently, only 0 and a positive number are implemented. This allows
2397 us to remove the remaining field from the conn_rec structure, which
2401 *) Big cleanup of the input filtering. The goal is that http_filter
2402 understands two conditions, headers and body. It knows where it is
2403 based on c->remaining. If c->remaining is 0, then we are in headers,
2404 and http_filter returns a line at a time. If it is not 0, then we are
2405 in body, and http_filter returns raw data, but only up to c->remaining
2406 bytes. It can return less, but never more.
2407 [Greg Ames, Ryan Bloom, Jeff Trawick]
2409 *) mod_cgi: Write all of the request body to the child, not just what
2410 the kernel would accept on the first write. [Jeff Trawick]
2412 *) Back out the change that moved the brigade from the core_output_filters
2413 ctx to the conn_rec. Since all requests over a given connection
2414 go through the same core_output_filter, the ctx pointer has the
2418 *) Fix another bug in the send_the_file() read/write loop. A partial
2419 send by apr_send would cause unsent data in the read buffer to
2420 get clobbered. Complete making send_the_file handle partial
2421 writes to the network.
2424 *) Fix a couple of type fixes to allow compilation on AIX again
2425 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2427 *) Fix bug in send_the_file() which causes offset to be ignored
2428 if there are no headers to send.
2431 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2432 filter. Useful for supporting Windows 9* with a binary
2433 compiled on Windows NT.
2436 Changes with Apache 2.0a7
2438 *) Reimplement core_output_filter to buffer/save bucket brigades
2439 across multiple calls to the core_filter. The brigade will be
2440 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2441 thresholds are hit or the EOS bucket is received.
2444 *) Create experimental filter (buffer_filter) that coalesces bytes
2445 into one large buffer before invoking the next filter in the
2446 chain. This filter is particularly useful with the current
2447 implementation of mod_autoindex when it inserted above the
2448 chunk_filter. mod_autoindex generates a lot of brigades that
2449 containing buckets holding just a few bytes each. The
2450 buffer_filter coalesces these buckets into a single large bucket.
2453 *) Add apr_sendfile() support into the core_output_filter.
2456 *) Add apr_sendv() support into the core_output_filter.
2459 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2460 [Mike Abbott <mja@sgi.com>]
2462 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2463 make much sense, because Apache uses buckets instead of BUFFs now.
2466 *) send_the_file now falls back to a read/write loop on platforms that
2467 do not have sendfile.
2468 [Ryan Bloom and Brian Havard]
2470 *) Install apachectl correctly, and substitute the proper values so
2471 that it works again. [Ryan Bloom]
2473 *) Better(??) handle platforms that lack sendfile().
2476 *) APR now has UUID generation/formatting/parsing support.
2479 *) Begin the http_filter. This is an input filter that understands
2480 the absolute basic amount required to parse an HTTP Request. The
2481 goal is to be able to split headers from request body before passing
2482 the data back to the other filters.
2485 *) Bring forward from 1.3.13 the config directory implementation
2488 *) install apxs if it is created
2491 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2492 conversions. [William Rowe]
2494 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2495 ap_add_output_filter(). [Jeff Trawick]
2497 *) Multiple build and configuration fixes
2500 -add datadir and localstatedir substitutions
2502 -fix logfilename misspelling
2503 -fix evaluation of installation dir variables and
2504 -replace $foobar by $(foobar) to be usefull in the makefile
2508 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2509 $CC_FOR_BUILD is still missing
2510 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2511 -add missing "AR=@AR@" to severaly Makefile.in's
2512 -cache result for "struct rlimit"
2513 -compile all helper programs with native and cross compiler
2514 and use the native version to generate header file
2515 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2517 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2519 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2521 *) Fix a bug where a client which only sends \n to delimit header
2522 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2523 message. Start working on ebcdic co-existance with input
2525 [William Rowe, Greg Ames]
2527 *) If mod_so is enabled in the server always create libexec, even
2528 if there are no modules installed in this directory. This is a
2529 requirement for APXS to work correctly.
2532 *) Connection oriented output filters are now stored in the
2533 conn_rec instead of the request_rec. This allows us to add the
2534 output filter in the pre-connection phase instead of the
2535 post_read_request phase, which keeps us from trying to write an
2536 error page before we have a filter to write to the network.
2537 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2539 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2540 mmap can be used across multiple buckets (default_handler with
2541 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2542 the mmap itself can't be associated with the bucket.
2545 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2548 *) Radical surgery to improve mod_isapi support under Win32.
2549 Includes a number of newer ServerSupportFunction calls, support
2550 for ReadClient (in order to retrieve POSTs greater than 48KB),
2551 and general bug fixes to more reliably load ISAPI .dll's and
2552 prevent leaking handle resources. Note: There are still
2553 discrepancies between IIS's and Apache's ServerVariables, and
2554 async calls are still not supported. Additional warnings are
2555 logged to facilitate debugging of unsupported ISAPI calls.
2558 *) Add input filtering to Apache. The basic idea for the input
2559 filters is the same as the ideas for output filters. The biggest
2560 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2561 should be called, and the order of execution for the filter itself is
2562 different. When writing an output filter, a brigade is passed in,
2563 and filters operate directly on that brigade, when done, they call
2564 ap_pass_brigade. Input filters are the exact opposite. Because input
2565 is not a push operation, filters first call ap_get_brigade. When this
2566 function returns, the input filter will be left with a valid brigade.
2567 The input filter should then operate on the brigade, and return.
2570 *) Fix building on BSD/OS using its native make. The build system
2571 falls back to the BSD .include directive on that host platform.
2574 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2575 SHA1 and plaintext password encodings. Make feature tests a
2576 bit more flexible. [William Rowe]
2578 *) Charset translation: mod_charset_lite handles output content
2579 translation in a filter. mod_charset_lite no longer ignores
2580 subrequests. A bunch of cruft related to BUFF's support for
2581 translating request and response bodies was removed.
2584 *) Move the addition of the CORE filter to the post_read_request
2585 hook in http_core.c. This removes the need to add the filter in
2586 multiple places and allows for an SSL module to be added much
2587 simpler. [Ryan Bloom]
2589 *) Fix a security problem that affects certain configurations of
2590 mod_rewrite. If the result of a RewriteRule is a filename that
2591 contains expansion specifiers, especially regexp backreferences
2592 $0..$9 and %0..%9, then it may be possible for an attacker to
2593 access any file on the web server. [Tony Finch]
2595 *) Fix a bug where errors that are detected during early request parsing
2596 don't produce visible HTTP error messages at the browser, because
2597 the core_filter wasn't present. [Greg Ames]
2599 *) Provide apr_socklen_t as a portability aid.
2600 [Victor J. Orlikowski]
2602 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2603 as well as a comment arg to the add, adduser and update cmds.
2604 update allows the user to clear or preserve pw/groups/comment.
2605 Fixed a bug in dbmmanage that prevented the check option from
2606 parsing a password followed by :group... text. Corrected the
2607 seed calcualation for Win32 systems, and added -lsdbm support.
2610 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2613 *) Avoid a segfault when parsing .htaccess files. An
2614 uninitialized tree pointer was passed to ap_build_config().
2617 *) Change the way that inet_addr & inet_network are checked for
2618 in APR's configure process to allow BeOS BONE to correctly
2619 find them. With this change BeOS BONE now builds from source
2620 with no problems. [David Reid]
2622 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2623 the end of the parameters to execve() was stored in the wrong
2624 location, overlaying the storage beyond the newargs[] array and
2625 also passing uninitialized storage to execve(), which would
2626 sometimes fail with EFAULT. [Jeff Trawick]
2628 *) Fix a bug parsing configuration file containers. With a sequence
2629 like this in the config file
2631 <IfModule mod_kilroy.c>
2634 <IfModule mod_lovejoy.c>
2639 the second container would be terminated at the blank line due to
2640 sediment in the buffer from reading the prior </IfModule> and an
2641 error message would be generated for the real </IfModule> for the
2642 second container. Also due to this problem, any two characters
2643 could be used for "</" in the close of a container.
2646 *) ap_add_filter prototype changed to remove the ctx pointer. The
2647 pointer still remains in the filter structure, but it can not be
2648 a part of the ap_add_filter prototype. The reason is that when
2649 the core uses AddFilter to add a filter to the stack it doesn't
2650 know how to allocate the ctx pointer, or even how much memory should
2651 be allocated. The filters will have to be responsible for allocating
2652 the ctx memory when they need it.
2655 *) Add an AddFilter directive. This directive takes a list of filters
2656 that should be activated for the requested resource.
2659 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2660 some other platforms). [Jeff Trawick]
2662 *) Modify mod_include to be a filter. Currently, it has only been tested
2663 on actual files, but it should work for CGI scripts too.
2666 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2667 writes. apr_flush() for Unix: handle interrupted writes.
2670 *) NameVirtualHost can now take "*" as an argument instead of
2671 an IP address. This allows you to create a purely name-based
2672 virtual hosting server that does not have any IP addresses in
2673 the configuration file and which ignores the local address
2674 of any connections. PR #5595, PR #4455 [Tony Finch]
2676 *) Fix some compile warnings in mod_mmap_static.c
2677 [Mike Abbott <mja@sgi.com>]
2679 *) Fix chunking problem with CGI scripts. The general problem was that
2680 the CGI modules were adding an EOS bucket and then the core added an
2681 EOS bucket. The chunking filter finalizes the chunked response when it
2682 encounters an EOS bucket. Because two EOS buckets were sent, we
2683 finalized the response twice. The fix is to make sure we only send one
2684 EOS, by utilizing a flag in the request_rec.
2687 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2688 and Win32. Previously, the first read from an apr_file_t set up via
2689 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2691 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2692 bucket, instead of using BUFF's and ap_r*.
2695 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2696 [Mike Abbott <mja@sgi.com>]
2698 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2699 code to use APR file's directly instead of going through BUFFs.
2702 *) Fix compile break on some platforms for mod_mime_magic.c
2703 [John K. Sterling <sterling@covalent.net>]
2705 *) Fix merging of AddDefaultCharset directive.
2706 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2708 *) Minor revamp of the rlimit sections of code. We now test
2709 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2710 is now "available" even if the platform doesn't support
2711 the rlimit family (it's just a noop though). [Jim Jagielski]
2713 *) Migrate the pre-selection of which MPM to use for specific
2714 platforms to hints.m4, which contains (or should contain)
2715 all platform specific "hints". [Jim Jagielski]
2717 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2720 *) Add tables with non-string/binary values to APR.
2723 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2726 *) Update PCRE to version 3.2. [Ryan Bloom]
2728 *) Change the way buckets' destroy functions are called so that
2729 they can be more directly used when changing the type of a
2730 bucket in place. [Tony Finch]
2732 *) Add generic support for reference-counting the resources used by
2733 buckets, and alter the HEAP and MMAP buckets to use it. Change
2734 the way buckets are initialised to support changing the type of
2735 buckets in place, and use it when setting aside TRANSIENT buckets.
2736 Change the implementation of TRANSIENT buckets so that it can be
2737 mostly shared with IMMORTAL buckets, which are now implemented.
2740 Changes with Apache 2.0a6
2742 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2744 *) Add a chunking filter to Apache. This brings us one step closer
2745 to removing BUFF. [Ryan Bloom]
2747 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2748 added to the stack is the last filter to be called. [Ryan Bloom]
2750 *) Apache 2.0 has been completely documented using Scandoc. The
2751 docs can be generated by running 'make docs'. [Ryan Bloom]
2753 *) Add filtered I/O to Apache. This is based on bucket brigades,
2754 Currently the buckets still use BUFF under the covers, but that
2755 should change quickly. The only currently written filter is the
2756 core filter which just calls ap_bwrite. [The Apache Group]
2758 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2759 built with thread support. [Jeff Trawick]
2761 *) Abort configuration if --with-layout was specified and there's
2762 no layout definition file. [Ken Coar]
2764 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2766 *) Add support for extension methods for the Allow response header
2767 field, and an API routine for accessing r->allowed and the
2768 list of extension methods in a unified manner. [Ken Coar]
2770 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2771 [Rob Simonson <simo@us.ibm.com>]
2773 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2774 APACHE_XLATE builds. [Jeff Trawick]
2776 *) A configuration file parsing problem was fixed. When the
2777 configuration file started with an IfModule/IfDefine container,
2778 only the last statement in the container would be retained.
2781 Changes with Apache 2.0a5
2783 *) Perchild is serving pages after passing them to different child
2784 processes. There are still a lot of bugs, but this does work. I
2785 have made requests against the same installation of Apache, and had
2786 different servers use different user IDs to serve the responses.
2787 This change moves to using socketpair instead of an AF_UNIX socket.
2790 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2791 It can't seem to pass between child processes yet, but I think we
2792 are closer now than before. This moves us back to using Unix
2793 Domain Sockets. [Ryan Bloom]
2795 *) libapr functions and types renamed with apr_ prefix.
2796 #include "apr_compat.h" for 1.3.x backwards compat
2799 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2800 return the right information on the local socket address.
2801 [Gregory Nicholls <gnicholls@level8.com>]
2803 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2804 [Gregory Nicholls <gnicholls@level8.com>]
2806 *) Add an option to not detach from the controlling terminal without
2807 going into single process mode. This allows for much easier
2808 debugging of the process startup code. [Ryan Bloom]
2810 *) ab: don't use perror() to report the failure of an APR function.
2813 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2814 scoreboard on graceful restarts.
2817 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2818 An invalid ap_proc_t was passed to ap_create_process().
2821 *) Allow modules to register filters. Those filters are still
2822 never called, but this is a step in the right direction.
2823 [Ryan Bloom and Greg Stein]
2825 *) Register the mod_cgid daemon process for cleanup so that it is
2826 killed at termination if it does not die when the parent gets
2827 SIGTERM. This change is to fix occasional problems where the
2828 process stays around. Bugs in similar logic in mod_rewrite and
2829 mod_include were also fixed. [Jeff Trawick]
2831 *) Fix a bug in the time handling. Basically, we were imploding a time
2832 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2833 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2834 uses those two fields to adjust the time value. Because of the HTTP
2835 spec, both of those values can be zero'ed out safely. This fixes
2836 the bug correctly. [Ryan Bloom]
2838 *) Fix a couple of place in the Windows code where the wrong error
2839 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2841 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2843 *) Added the APR_EOL_STR macro for platform dependent differences in
2844 logfiles and other raw text (such as all APR files). Fixes logfiles
2845 not terminated with cr/lf sequences in Win32. [William Rowe]
2847 *) Move all strings functions in APR to src/lib/apr/strings and create
2848 apr_strings.h for the prototypes. [Ryan Bloom]
2850 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2851 to repeat the syscall until we stop getting EINTR. I noticed a
2852 related problem at termination (SIGTERM) on FreeBSD when using
2853 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2854 implementation work properly with child init. Previously, ap_lock()
2855 was essentially a no-op because all children were using different
2856 locks and thus nobody ever blocked. [Jeff Trawick]
2858 *) The htdocs/ tree has been moved out of the CVS source tree into
2859 a separate area for easier development. This has NO EFFECT on
2860 end-users or Apache installations. [Ken Coar]
2862 *) Integrate the mod_dav module for WebDAV protocol handling. This
2863 adds the dav and dav_fs modules, the SDBM library, and additional
2864 XML handling utilities. [Greg Stein]
2866 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2869 *) Update the lib/expat-lite/ library (bring forward changes from
2870 the Apache 1.3 repository). [Greg Stein]
2872 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2873 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2875 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2876 machines where sendfile is detected, but nobody has written ap_sendfile.
2877 [Dave Hill <ddhill@zk3.dec.com>]
2879 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2881 *) ab would start up more connections than needed, then quit when the
2882 desired number were finished. Also fixed a logic error involving
2883 ab keepalives. [Victor J. Orlikowski]
2885 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2886 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2887 timeouts (i.e, if a timeout was specified, the pipe reverted to
2888 a full blocking pipe). Now the behaviour is more in line with
2889 Unix non-blocking pipes.
2892 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2893 cache open file handles along with accept socket reuse enables
2894 Apache 2.0 to serve non-keepalive requests for static files at
2895 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2896 and Apache 2.0 will serve almost 1200 rps on my system).
2899 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2900 supports two config directives, mmapfile (same behavious as
2901 mod_mmap_static) and cachefile. Use the cachefile directive
2902 to cache open file handles. This directive only works on systems
2903 that have implemented the ap_sendfile API. cachefile works today
2904 on Windows NT, but has not been tested on any flavors of Unix.
2907 *) Cleanup the configuration. With the last few changes the
2908 configuration process automatically:
2909 inherits information about how to build from APR. Allowing
2910 APR to inform Apache that it should or should not use -ldl
2912 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2913 based on the threading model
2915 Apache calls APR's configure process before finishing it's
2916 configuration processing, allowing for more information flow
2921 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2922 with non-zero argument makes the socket non-blocking. BeOS and
2923 OS/2 already worked this way. [Jeff Trawick]
2925 *) ap_close() now calls ap_flush() for buffered files, so write
2926 operations work a whole lot better on buffered files.
2929 *) Fix error messages issued from MPMs which explain where to change
2930 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2933 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2934 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2935 now the way that the blocking state of a pipe is manipulated.
2936 ap_block_pipe() is gone. [Jeff Trawick]
2938 *) Correct the problem where the only local host name that the IP stack
2939 can discover are 'undotted' private names. If no fully qualified
2940 domain name can be identified, the default ServerName will be set to
2941 the machine's IP address string. A warning is always provided if the
2942 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2944 *) Repair problems with config file processing which caused segfault
2945 at init when virtual hosts were defined and which caused ServerName to
2946 be ignored when there was no valid DNS setup. [Jeff Trawick]
2948 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2950 *) Add ap_sendfile implementation for AIX
2951 [Victor J. Orlikowski]
2953 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2954 apr_network_io.h, and apr_thread_proc.h.
2955 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2957 *) Bring the allocation and pool debugging code back into a working
2958 state. This will need to be tested as so far it's only been used on
2961 *) Change configuration command setup to be properly typesafe when in
2962 maintainer mode. Note that this requires a compiler that can initialise
2963 unions. [Ben Laurie]
2965 *) Turn on buffering for config file reads. Part of this was to
2966 repair buffered I/O support in Unix and implement buffered
2967 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2969 *) Win32: Fix problem where UTC offset was not being set correctly
2970 in the access log. Problem reported on news group by Jerry Baker.
2973 *) Fix segfault when reporting this type of syntax error:
2974 "</container> without matching <container> section", where
2975 container is VirtualHost or Directory or whatever.
2978 *) Prevent the source code for CGIs from being revealed when using
2979 mod_vhost_alias and the CGI directory is under the document root
2980 and a user makes a request like http://www.example.com//cgi-bin/cgi
2981 as reported in <news:960999105.344321@ernani.logica.co.uk>
2984 *) Add support for the new Beos NetwOrking Environment (BONE)
2987 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2988 final input char is incomplete; ap_bwrite_xlate() now handles
2989 incomplete final input chars. [Jeff Trawick]
2991 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2992 that a bhalfduplex call occurs before logging or else DNS and
2993 such can delay the last packet of the response. [Dean Gaudet]
2995 *) Some syscall reduction in APR on unix -- don't seek when setting
2996 up an mmap; and don't fcntl() more than once per socket.
2999 *) When mod_cgid is started as root, the cgi daemon now switches
3000 to the configured User/Group (like other httpd processes)
3001 instead of continuing as root. [Jeff Trawick]
3003 *) The prefork MPM now uses an APR lock for the accept() mutex.
3004 It has not been getting a lock at all recently. httpd -V now
3005 displays APR's selection of the lock mechanism instead of the
3006 symbols previously respected by prefork. [Jeff Trawick]
3008 *) Change the mmap() feature test to check only for existence.
3009 The previous check required features not used by Apache.
3012 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
3013 sometimes mangled. The len parm to accept() was not
3014 initialized, leading sometimes to an endless loop of failed
3015 accept() calls on OS/390 and anywhere else that failed the call
3016 if the len was negative. Use <sys/un.h> for struct sockaddr_un
3017 instead of declaring it ourselves to fix a compilation problem
3018 on Solaris. [Jeff Trawick]
3020 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
3022 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
3024 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
3026 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
3027 initialization if ALLOC_DEBUG is defined; no known symptom
3028 otherwise. [Jeff Trawick]
3030 *) Fix typo in configure script when checking for mod_so. bash
3031 doesn't seem to have a problem but /bin/sh on Solaris does.
3032 Symptom: "./configure: test: unknown operator =="
3035 *) Rebind the Win32 NT and 9x services control into the MPM.
3036 All console, WinNT SCM and Win9x pseudo-service control code is
3037 now wrapped within the WinNT MPM.
3040 *) Make a copy of getenv("PATH") before storing for later use. Some
3041 getenv() implementations use the same storage for successive calls.
3042 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
3044 *) Server Tokens work in 2.0 again. This also propogates the change
3045 to allow just the product name in the server string using
3049 Changes with Apache 2.0a4
3051 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
3052 won't need to call it. [Greg Ames, Jeff Trawick]
3054 *) Move pre_config hook call to between configuration read and config
3055 tree walk. This allows all modules to implement pre_config hooks
3056 and know that they will be called at an appropriate time.
3059 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
3062 *) Add pre-config hooks back to all modules.
3065 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
3066 ContentDigest enabled and we can't/don't mmap the file.
3069 *) We now report the correct line number for syntax errors in config
3070 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
3072 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
3073 related bugs, and changed shmem/locking to use apr API. Shared-mem
3074 is currently disabled, however, because of problems with graceful
3075 restarts. [Ronald Tschalär]
3077 *) Fix corruption of IFS variable in --with-module= handling.
3078 Depending on the user's shell or customization thereof, there
3079 would be errors generating ap_config_auto.h later in the configure
3080 procedure. [Jeff Trawick]
3082 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
3083 isn't used (as in 1.3), except that on Unix it is now logged via
3084 ap_log_rerror() instead of by the child having STDERR_FILENO refer
3085 to the error log. [Greg Ames, Jeff Trawick]
3087 *) Add '-D' argument processing for run time configuration defines.
3090 *) Organize http_main.c as independent code, such that no code or
3091 global data is exported from it. WIN32 will dynamically link it
3092 to the server core, so this will prevent mutual dependency.
3095 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
3096 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
3099 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
3100 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
3102 *) Add mod_charset_lite for configuring character set translation.
3105 *) Add '-n' option to htpasswd to make it print its user:pw record
3106 on stdout rather than having to frob a text file. [Ken Coar]
3108 *) Fix saferead. Basically, we flush the output buffer if a read on the
3112 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
3113 a conversion is single-byte only. [Jeff Trawick]
3115 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
3116 the BeOS 5.0 documentation says that shutdown doesn't work yet.
3119 *) Fix some minor errors where pid was being manipulated as an int
3120 instead of the portable pid_t. [Roy Fielding]
3122 *) Fix some error log prints that were printing the pointer to a
3123 structure rather than the pid within the structure.
3124 [Jeff Trawick, Roy Fielding]
3126 *) ab: Fix a command-line processing bug; track bad headers in
3127 err_response; support reading headers up to 2K.
3128 [Ask Bjoern Hansen <ask@valueclick.com>]
3130 *) Fix ap_resolve_env() so that it handles new function added in a prior
3131 alpha (see "Added the capability to do ${ENVVAR} constructs in the
3132 config file.") as well as the constructs used by mod_rewrite.
3133 [Paul Reder <rederpj@raleigh.ibm.com>]
3135 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
3137 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
3138 APR to perform translation, instead of accessing the hard-coded tables
3139 in 1.3's ebcdic.c. [Jeff Trawick]
3141 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
3144 *) Add the ability to hook into the config file reading phase. Basically
3145 if a directive is specified EXEC_ON_READ, then when that directive is
3146 read from the config file, the assocaited function is executed. This
3147 should only be used for those directives that must muck with HOW the
3148 server INTERPRETS the config. This should not be used for directives
3149 that re-order or replace items in the config tree. Those changes should
3150 be made in the pre-config step.
3153 *) Add mod_example to the build system.
3156 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
3157 byte character sets. [Jeff Trawick]
3159 *) Pick up various EBCDIC fixes from 1.3 (from Martin
3160 Kraemer and Oliver Reh originally according to the change log).
3163 *) Fix a couple of problems in RFC1413 support (controlled by the
3164 IdentityCheck directive). Apache did not build the request string
3165 properly and more importantly Apache would loop forever if the
3166 would-be ident server dropped the connection before sending a
3167 properly terminated response. [Jeff Trawick]
3169 *) apxs works in 2.0.
3172 *) Reliable piped logs work in 2.0.
3175 *) Introduce a hash table implementation into APR to be used for
3176 replacing tables and other random data structures in Apache.
3179 *) Add some more error reporting to htpasswd in the case of problems
3180 generating or accessing the temporary file. Also, pass in a
3181 buffer if the implementation knows how to use it (i.e., if L_tmpnam
3182 is defined). [Ken Coar]
3184 *) Configure creates config.nice now containing your configure
3185 options. Syntax: ./config.nice [--more-options]
3188 *) Fix various return code problems in APR on Win32. For most of
3189 these, APR was returning APR_EEXIST instead of GetLastError()/
3190 WSAGetLastError(). [Jeff Trawick]
3192 *) Make piped logs work again in version 2.0
3195 *) Add VPATH support to UNIX build system of Apache and APR.
3198 *) Fix ap_tokenize_to_argv to respect the const arguments that are
3202 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
3203 Patch submitted to author.
3206 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
3207 /sbin in PATH on FreeBSD (all submitted to rse previously)
3210 *) Fix building Pthread-based MPMs on OpenBSD
3211 [Sascha Schumann] PR#26
3213 *) Fix ap_readdir() problem on systems where d_name[] field in
3214 struct dirent is declared with only one byte. (This problem only
3215 affected multithreaded builds.) This caused a segfault during
3216 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3217 least). [Jeff Trawick]
3219 *) Fix some make-portability problems on at least Tru64, Irix
3221 [Sascha Schumann] PR#18, PR#39
3223 *) Add ap_sigwait() to support old-style sigwait() on systems
3224 like OS/390 and UnixWare.
3227 *) Add POSIX-thread flags for more platforms.
3230 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3231 (on Unix, at least) to handle resolver errors. Fix a bug in
3232 the definition of APR_ENOMEM so that ap_strerror() can spit
3233 out the correct error message for it.
3236 Changes with Apache 2.0a3
3238 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3241 *) API: *HOOK* macros now have an AP_ prefix
3244 *) Win32: Eliminate redundant calls to initialize winsock.
3245 [Tim Costello <timcostello@ozemail.com.au>]
3247 *) Fix bugs initializing ungetchar for pipes.
3248 [Chia-liang Kao <clkao@CirX.ORG>]
3250 *) The ab program in the src/support directory is now portable using
3254 *) Support directory is being compiled when the server is built
3257 *) The configure option --with-program-name has been added to allow
3258 developers to rename the executable at configure time. This also
3259 changes the name of the config files to match the executable's name.
3262 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3263 containing version numbers. [Martin Pool]
3265 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3266 Unix; access_log and error_log now created with these perms; non-
3267 Unix is unaffected [Jeff Trawick]
3269 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3270 Replaced more magic numbers with MD5_DIGESTSIZE.
3271 [William Rowe, Roy Fielding]
3273 *) Win32: Get mod_auth_digest compiling and added to the Windows
3274 build environment. Not tested and I'd be suprised if it
3275 actually works. [Bill Stoddard]
3277 *) Revamp the Win32 make environment. Makefiles have been removed and
3278 Apache.dsw created to bring together all the pieces. Create new file
3279 os/win32/BaseAddr.ref to define module base addresses (to prevent
3280 dll relocation at start-up).
3281 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3283 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3284 of the \015, \012, and \015\012 constants with macros.
3285 [Greg Ames <gregames@us.ibm.com>]
3287 *) Add ap_xlate_open() et al for translation of text between different
3288 character sets. The initial implementation requires iconv().
3291 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3292 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3294 *) CGI output is being timed out now.
3297 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3298 is used by the new apr file. There is no reason to create a new file
3299 with the same lifetime as the original file.
3302 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3303 module base addresses. This will help shooting seg faults
3304 in the field. [William Rowe <wrowe@lnd.com>]
3306 *) Update Apache on Windows documentation. Add new document
3307 describing how to compile Apache on Windows.
3308 [William Rowe <wrowe@lnd.com>]
3310 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3311 microseconds instead of seconds. Some storage leaks and other
3312 minor bugs in related code were fixed. [Jeff Trawick]
3314 *) Win32: First cut at getting mod_isapi working under 2.0
3315 [William Rowe <wrowe@lnd.com>]
3317 *) First stab at getting mod_auth_digest working under 2.0
3318 quick change summary:
3319 - moved the random byte generation (ap_generate_random_bytes) into APR
3320 - now uses ap_time_t
3321 - compiles and runs on linux
3323 [Brian Martin <bmartin@penguincomputing.com>]
3325 *) Win32: Move the space stripping of physical service names
3326 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3327 unresolved symbol. Add dependency checking to the
3328 CreateService call to ensure TCPIP and AFP (winsock) is started
3330 [William Rowe <wrowe@lnd.com>]
3332 *) Win32: Add code to perform latebinding on functions that may
3333 not exist on all levels of Windows where Apache runs. This
3334 is needed to allow Apache to start-up on Win95/98. All calls
3335 to non portable functions should be protected with
3336 ap_oslevel checks to prevent runtime segfaults.
3337 [William Rowe <wrowe@lnd.com>]
3339 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3341 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3343 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3344 This addresses PR 1623. Still need to address timing out runaway
3345 CGI scripts. [Bill Stoddard]
3347 *) Win32: Make ap_stat Windows 95/98 friendly
3348 [William Rowe <wrowe@lnd.com>]
3350 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3351 always fail. Need to initialise the dwOSVersionInfoSize member of the
3352 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3355 The patch also enhances ap_get_oslevel (and the associated enum) to
3356 handle selected service packs for NT4, and adds recognition for
3357 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3358 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3359 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3361 *) Get mod_rewrite building and running, and mod_status building for Win NT
3362 [Allan Edwards <ake@raleigh.ibm.com>]
3364 *) Patch to port mod_auth_db to the 2.0 api and also to support
3365 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3366 2.7.7. It should work with version 1 as well but I haven't tested it.
3367 [Brian Martin <bmartin@penguincomputing.com>]
3369 *) Get APR DSO code working under Windows. Includes cross platform
3371 [Tim.Costello@BTFinancialgroup.com]
3373 *) Fix some of the Windows APR time functions.
3376 *) FAQ changes related to tidying up historical documents on the web site.
3377 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3379 *) Move Windows DSO code into APR.
3382 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3383 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3384 at build time. At this point, the server will not compile on Windows because
3385 of the recent DSO commits. Fixing those next.
3386 [Bill Rowe & Bill Stoddard]
3388 *) Added error checking for file I/O APR routines.
3389 [Jon Travis <jtravis@covalent.net>]
3391 *) APR: Don't use the values of resolver error codes for the
3392 corresponding APR error codes. On Unix and Win32, return the
3393 proper APR error code after a resolver error. [Jeff Trawick]
3395 Changes with Apache 2.0a2
3397 *) Renamed the executable back to httpd on all platforms other
3401 *) Allow BeOS to survive restarts, log properly and a few
3402 small things it had problems with due to the way it setup
3403 users and groups. [David Reid]
3405 *) Get mod_rewrite working with APR locks
3406 [Paul Reder <rederpj@raleigh.ibm.com>]
3408 *) Actually remove the sempahore when the lock cleanup routine
3409 is called on BeOS. [David Reid]
3411 *) Clear hook registrations between reads of the config file.
3412 When DSOs are unloaded and re-loaded the old hook pointers may
3413 no longer be valid. This fix eliminates potential segfaults.
3414 [Allan Edwards <ake@raleigh.ibm.com>]
3416 *) Fix a problem with Sigfunc not being defined or bypassed
3417 if sigaction() wasn't found. [Jim Jagielski]
3419 *) Fix the locking mechanism on BSD variants. They now use fcntl
3420 locks. This allows the server to start and serve pages.
3423 *) First cut at getting the Win32 installer to work
3424 [William Rowe <wrowe@lnd.com>]
3426 *) Get htpasswd compiling under Windows
3427 [William Rowe <wrowe@lnd.com>]
3429 *) Change the log message for a bind() failure to show the
3430 interface and port number. [Jeff Trawick]
3432 *) Import the documentation from 1.3.12 and bring parts of it
3433 up-to-date with respect to the changes that have occurred
3437 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3438 now logged correctly on BeOS.
3441 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3442 Makefile.win includes the same user interface as the old
3444 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3446 *) Win32 exec now uses COMSPEC environment string for command
3447 shell path resolution.
3448 [William Rowe <wrowe@lnd.com>] PR#3715
3450 *) Win32: ap_connect() was not returning correct error condition
3452 [Allen Prescott <allen@clanprescott.com>]
3454 *) Win32: ap_open() was broken on Win9x because an NT-specific
3455 flag was passed to CreateFile. ap_puts() added an unnecessary
3457 [Jeff Trawick <trawick@us.ibm.com>]
3459 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3460 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3461 confusing ee/et name and made all extensions language/dialect
3462 rather than country reflecting. Changed example files to
3463 explicit reflect the ISO charset and added a few common
3464 ones to the example config [dirkx]
3466 *) Extend external module capability. To use this, you call
3467 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3470 *) Backported the various "default charset" fixes from 1.3.12,
3471 including the AddDefaultCharset directive. [Jim Jagielski]
3473 *) Added the capability to do ${ENVVAR} constructs in the
3474 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3475 it does this on a line by line basis; i.e. if the envvar
3476 expands to something with spaces you have to protect it
3477 by adding quotes around it (Unless of course you expect it
3478 to contains more than one argument. Alternatively you
3479 can compile it on a per token basis; which is what people
3480 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3481 hampers fancier hacks.
3482 [Dirk-Willem van Gulik]
3484 *) Changed the 'ErrorDocument' syntax in that it NO longer
3485 supports the asymetric
3487 ErrorDocument 301 "Some message
3489 Note the opening " quote, without a closing quote. It now
3490 has either the following syntaxes
3492 ErrorDocument XXX /local/uri
3493 ErrorDocument XXX http://valid/url
3494 ErrorDocument XXX "Some Message"
3496 The recognition heuristic is: if it has a space it
3497 is a message. If it has no spaces and starts with a /
3498 or is a valid URL then treat it that way. Otherwise it
3499 is assumed to be a message.
3501 This breaks backward compatibility but makes live a hell
3502 of a lot easier for GUI's and config file parsers.
3503 [Dirk-Willem van Gulik]
3505 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3506 syntax into a 'on' or 'off' syntax. As it currently is the
3507 only non nesting token which uses NO_ARGS and thus is an
3508 absolute pain for any config interface automation. This
3509 breaks backward compatibility. [Dirk-Willem van Gulik]
3511 *) Add ability to add external modules to the build process. This is
3512 done with --with-module=/path/to/module. Modules can only be added
3513 as static modules at this point.
3516 Changes with Apache 2.0a1
3518 *) Fix FreeBSD 3.3 core dump.
3519 Basically, ap_initialize() needs to get called before
3520 create_process(), since create_process() passes op_on structure
3521 to semop() to get a lock, but op_on isn't initialized until
3522 ap_initialize() calls setup_lock(). Here is a slight
3523 rearrangement to main() which calls ap_initialize() earlier...
3524 [Jeff Trawick <trawick@us.ibm.com>]
3526 *) Enable Apache to use sendfile/TransmitFile API
3527 [Bill Stoddard, David Reid, Paul Reder]
3529 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3533 *) Make file I/O and network I/O writev/sendv APIs consistent.
3534 Eliminate use of ap_iovec_t and use Posix struct iovec.
3535 Use seperate variable on ap_writev to set the number of iovecs
3536 passed in and number of bytes written.
3539 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3540 with ap_create_file_iol(). ap_create_file_iol() requires that
3541 the file be opened prior to the call using ap_open().
3544 *) Port mod_include and mod_cgi to 2.0
3545 [Paul Reder, Bill Stoddard]
3547 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3548 bytes_read/bytes_written is always valid (never -1). Plus
3549 some fixes to buff.c to correct problems introduced by the
3550 errno => ap_status_t changes a while back. Plus a fix to
3551 chunked encoding introduced right at the beginning of 2.0.
3554 *) Revamped UNIX build system to use autoconf and libtool.
3555 [Manoj Kasichainula, Sascha Schumann]
3557 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3559 *) More rigorous checking of Host: headers to fix security problems
3560 with mass name-based virtual hosting (whether using mod_rewrite
3561 or mod_vhost_alias).
3562 [Ben Hyde, Tony Finch]
3564 *) Add back support for UseCanonicalName in <Directory> containers.
3565 [Manoj Kasichainula]
3567 *) Added APLOG_STARTUP log type. This allows us to write an error
3568 message without any of the date and time information. As a part
3569 of this change, I also removed all of the calls to fprintf(stderr
3570 and replaced them with calls to ap_log_error using APLOG_STARTUP
3571 writing to stderr is no longer portable, because we don't direct
3572 stderr to the error log on all platforms.
3575 *) Convert error logging functions to take errno as an argument.
3576 This makes our error logs more portable, because some Windows API's
3577 don't set errno. This change allows us to still output a valid
3578 message on all of our platforms.
3581 *) mod_mime_magic runs in 2.0-dev now.
3582 [Paul Reder <rederpj@raleigh.ibm.com>]
3584 *) sendfile has been added to APR.
3585 [John Zedlewski <zedlwski@Princeton.EDU>]
3587 *) buff.c has been converted to no longer use errno.
3588 [Manoj Kasichainula]
3590 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3591 interface adaption to APR functions did it. [Martin Kraemer]
3593 *) Support DSOs properly on 32-bit HP-UX 11.0
3594 [Dilip Khandekar <dilip@cup.hp.com>]
3596 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3597 [Ralf S. Engelschall]
3599 *) Cleaned APR build environment integration and bootstrap APR
3600 automatically for developers from src/Configure.
3601 [Ralf S. Engelschall]
3603 *) Fixed building of src/support/htpasswd.c
3604 [Ralf S. Engelschall]
3606 *) When generating the Location: header, mod_speling forgot
3607 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3610 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3612 *) Change all pools to APR contexts. This is the first step to
3613 incorporating APR into Apache. [Ryan Bloom]
3615 *) Move "handler not found" warning message to below the check
3616 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3617 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3619 *) Support line-continuation feature in config.option file and
3620 allow the loading of multiple option sections at once via
3621 ``--with-option=<section1>,<section2>,...''
3622 [Ralf S. Engelschall]
3624 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3626 Changes with Apache MPM
3628 *) Use asynchronous AcceptEx() and a completion port to accept and
3629 dispatch connections to threads in Windows NT/2000.
3632 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3635 *) Implement the APACI --with-option facility
3636 (per default used the config.option file).
3637 [Ralf S. Engelschall]
3639 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3641 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3642 Replace pre_connection module call with a register_hook call and
3643 implement pre_connection as a hook. The intent is that these hooks will
3644 be extended to allow Apache to be multi-protocol, and also to allow the
3645 calling order to be specified on a per-hook/per-module basis.
3648 *) Implement mpm_* methods as "modules". Each method gets its own
3649 subdir in src/modules (eg: src/modules/prefork). Selection
3650 of method uses Rule MPM_METHOD. [Jim Jagielski]
3652 *) Port the hybrid server from the apache-apr repository as
3653 mpm_mpmt_pthread. [Manoj Kasichainula]
3655 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3656 amongst the unix MPMs.
3658 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3659 signal handling for the new world order. [Dean Gaudet]
3661 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3662 of alloc.c for now. [Dean Gaudet]
3664 *) Handle partial large writes correctly. [Ben Laurie]
3666 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3667 based on IP/port. [Ben Laurie]
3669 *) Port a bunch of modules to the new module structure.
3670 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3672 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3674 *) Basic restructuring to introduce the MPM concept; includes various
3675 changes to the module API... better described by
3676 docs/initial_blurb.txt. [Dean Gaudet]
3678 Changes with Apache pthreads
3680 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3681 buff operations (generally over a network).
3682 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3684 *) Created http_accept abstraction. Added 4 new functions (not exported):
3685 init_accept(), begin_accepting_requests(), get_request(),
3686 stop_accepting_requests() [Bill Stoddard]
3688 *) Fix to ap_rprintf call that allows mod_info to work properly.
3689 [James Morris <jmorris@intercode.com.au>]
3691 *) user and ap_auth_type fields were moved from connection_rec to
3692 request_rec. [Ryan Bloom]
3694 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3695 needed in a threaded server.
3697 *) Initial pthread implementation from from Dean's apache-nspr code.
3698 [Bill Stoddard, Ryan Bloom]
3701 Changes with Apache 1.3.9
3703 *) Remove bogus error message when a redirect doesn't set Location.
3704 Instead, use an empty string to avoid coredump if the error message
3705 was supposed to include a location. [Roy Fielding]
3707 *) Don't allow configure to include mod_auth_digest unless it is
3708 explicitly requested, even if the user asked for all modules.
3711 *) Translate module names to dll names for OS/2 so that they are no more
3712 than 8 characters long and have an extension of "dll" instead of "so".
3715 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3716 Fix test-compile check to check for randbyte instead of trand32.
3717 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3718 and tweak to make Amaya happier. [Ronald Tschalär]
3720 *) Ensure that the installed expat include files are world readable,
3721 just like the other header files. [Martin Kraemer]
3723 *) Fixed generated AddModule adjustments in APACI's `configure' script
3724 in order to allow (new) modules like mod_vhost_alias to be handled
3725 correctly (which was touched by the adjustments for mod_alias).
3726 [Ralf S. Engelschall]
3728 *) For binary builds, add -R flag to apachectl to work around the lack of
3729 an absolute path to the ./libexec directory where the libhttp.ep file
3730 is needed for SHARED_CORE architectures. [Randy Terbush]
3732 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3733 problem observed by some Win95/98 users where they get CGI script
3734 output sent to the console. [Bill Stoddard]
3736 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3737 routines are now called ap_base64* and are 'plain' (i.e., no
3738 pool access or anything clever). Inside util.c the routines acting
3739 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3740 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3741 now but deprecated. [dirkx]
3743 *) Clean up the base64 and SHA1 additions and make sure they are
3744 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3745 files. [Roy Fielding]
3747 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3748 checking. Allow compiling on VS 6.0. [Randy Terbush]
3750 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3752 *) Use TestCompile to search for the truerand library (rather than blindly
3753 assuming its existence). If it is not found, complain (but do not
3754 exit - yet). [Martin Kraemer]
3756 *) We forgot to add the new exported function names to
3757 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3759 *) Add description of -T command-line option to usage().
3760 [Ralf S. Engelschall]
3762 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3763 searched only AFTER libap has been searched, because libap needs
3764 some symbols from libos. [Martin Kraemer]
3766 *) Fix conflict with original mod_digest related to the symbol of the
3767 module dispatch list (which has to be unique for DSO and follow the
3768 usual conventions for the installation procedure).
3769 [Ralf S. Engelschall]
3771 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3772 for other platforms as well. [Martin Kraemer]
3774 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3775 types by AP_LONG and replace reference to renamed variable 'ubuf'
3776 by 'buffer'. [Martin Kraemer]
3778 Changes with Apache 1.3.8 [not released]
3780 *) Flush the output buffer immediately after sending an error or redirect
3781 response, since the result may be needed by the client to abort a
3782 long data transfer or restart a series of pipelined requests.
3783 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3785 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3786 [Ian Turner <iant@sequent.com>] PR#4735
3788 *) Local struct mmap in http_core.c conflicted with system structure
3789 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3791 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3792 [Ronald Tschalär <ronald@innovation.ch>]
3794 *) Fix a memory leak where the module counts were getting messed
3795 up across restarts. [David Harris <dharris@drh.net>]
3797 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3798 properly in mod_access.
3799 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3801 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3802 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3804 *) PORT: Support for compaq/tandem/com.
3805 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3807 *) Added SHA1 password encryption support to easy migration from
3808 Netscape servers. See support/SHA1 for more information.
3809 Caused the separation of ap_md5.c into md5, sha1 and a general
3810 ap_checkpass.c with just a validate_passwd routine. Added a
3811 couple of flags to support/htpasswd. Some reuse of the to64()
3812 function; hence renamed to ap_to64().
3813 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3815 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3816 with ASCII/EBCDIC conversions in "ident" query.
3817 [David McCreedy <McCreedy@us.ibm.com>]
3819 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3820 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3821 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3823 *) Fix SIGSEGV on some systems because the Vary fix below included
3824 a call to table_do with a variable argument list that was not
3825 NULL terminated. Replaced with better implementation. [Roy Fielding]
3827 Changes with Apache 1.3.7 [not released]
3829 *) The "Vary" response header field is now sanitised right before
3830 the header is sent back to the client. Multiple "Vary" fields
3831 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3832 "Vary: host, negotiate, host, accept-language") are reduced to
3833 single instances. This is a better solution than the force-no-vary
3834 one (which is still valid for clients that can't cope with Vary
3835 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3837 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3839 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3840 least on Linux and FreeBSD for now.
3843 *) Win32: More apache -k restart work. Restarts are now honored
3844 immediately and connections in the listen queue are -not- lost.
3845 This is made possible by the use of the WSADuplicateSocket()
3846 call. The listeners are opened in the parent, duplicated, then
3847 the duplicates are passed to the child. The original listen sockets
3848 are not closed by the parent across a restart, thus the listen queue
3850 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3852 *) Fix handling of case when a client has sent "Expect: 100-continue"
3853 and we are going to respond with an error, but get stuck waiting to
3854 discard the body in the pointless hope of preserving the connection.
3855 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3857 *) Fix 'configure' to work correctly with SysV-based versions of
3858 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3860 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3861 built-in values. Add "-e" option which works like -i but doesn't
3862 install the DSO; useful for editing httpd.conf with apxs. Fix
3863 editing code so that multiple invocations of apxs -a will not
3864 create duplicate LoadModule/AddModule entries; apxs can now be
3865 used to re- enable/disable a module. [Wilfredo Sanchez]
3867 *) Win32: Update the server to use Winsock 2. Specifically, link with
3868 ws2_32.lib rather than wsock32.lib. This gives us access to
3869 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3870 Win 95 users may need to update their TCP/IP stack to pick up
3871 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3872 [Bill Stoddard stoddard@raleigh.ibm.com]
3874 *) Win32: Redirect CGI script stderr (script debug info) into the
3875 error.log when CGI scripts fail. This makes Apache on Win32
3876 behave more like Unix.
3877 [Bill Stoddard stoddard@raleigh.ibm.com]
3879 *) Fixed `httpd' usage display: -D was missing.
3880 [Ralf S. Engelschall] PR#4614
3882 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3883 [Ralf S. Engelschall] PR#4561, PR#4562
3885 *) OS/2: Fix problem with accept lock semaphores where server would die with
3886 "OS2SEM: Error 105 getting accept lock. Exiting!"
3887 [Brian Havard] PR#4505
3889 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3890 [Randy Terbush <randy@covalent.net>]
3892 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3893 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3895 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3896 command potentially _is_ GCC. [Ralf S. Engelschall]
3898 *) Fix apxs build issues on AIX
3899 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3901 *) DocumentRoot Checking: Under previous versions, when Apache
3902 first started up, it used to do a stat of each DocumentRoot to
3903 see if it existed and was a directory. If not, then an error
3904 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3905 does not exist, you will get error messages in error_log. If
3906 the '-t' command line option is used (to check the configuration)
3907 the check of DocumentRoot IS performed. An additional command
3908 line option, '-T', has been added if you want to avoid the
3909 DocumentRoot check even when checking the configuration.
3912 *) Win32: The query switch "apache -S" didn't exit after showing the
3913 vhost settings. That was inconsistent with the other query functions.
3914 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3916 *) Win32: Changed behaviour of apache -k restart.
3917 Previously, the server would drain all connections in the stack's
3918 listen queue before honoring the restart. On a busy server, this
3919 could take hours. Now, a restart is honored almost immediately.
3920 All connections in Apache's queues are handled but connections in
3921 the stack's listen queue are discarded. Restart triggered by
3922 MaxRequestPerChild is unchanged.
3923 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3925 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3926 the accept loop. Good for a 5% performance boost. Cleaned up
3927 parent/child process management code.
3928 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3930 *) Added ceiling on file size for memory mapped files.
3931 [John Giannandrea <jg@meer.net>] PR#4122
3933 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3934 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3935 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3937 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3938 use this at least for Expat. [Ralf S. Engelschall]
3940 *) Allow .module files to specify libraries with Lib:.
3943 *) Allow SetEnvIf[NoCase] to test environment variables as well
3944 as header fields and request attributes. [Ken Coar]
3946 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3947 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3949 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3950 never accepted into any standard, and it opens up certain DoS
3951 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3953 *) TestCompile updated. We can now run programs and output the
3954 results during the Configure process. [ Jim Jagielski]
3956 *) The source is now quad (long long) aware as needed. Specifically,
3957 the Configure process determines the correct size of off_t and
3958 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3959 provides for the 'q' format qualifier (if quads are not available,
3960 'q' is silently "demoted" to long). [Jim Jagielski]
3962 *) When the username or password fed to htpasswd is too long, include the
3963 size limit in the error message. Also report illegal characters
3964 (currently only ':') in the username. Add the size restrictions
3965 to the man page. [Ken Coar]
3967 *) Fixed the configure --without-support option so it doesn't result in
3968 an infinite loop. [Marc Slemko]
3970 *) Piped error logs could cause a segfault if an error occured
3971 during configuration after a restart.
3972 [Aidan Cully <aidan@panix.com>] PR#4456
3974 *) If a "Location" field was stored in r->err_headers_out rather
3975 than r->headers_out, redirect processing wouldn't find it and
3976 the server would core dump on ap_escape_html(NULL). Check both
3977 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3978 if Location isn't set. [Doug MacEachern, Ken Coar]
3980 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3981 of the Expat 1.0.2 distribution. [Greg Stein]
3983 *) Replace regexec() calls with calls to a new API stub function
3984 ap_regexec(). This solves problems with DSO modules which use the regex
3985 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3987 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3988 environment variables can be set according to the protocol version
3989 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]

4006 *) Support for server-parsed and multiview-determined ReadmeName and
4007 HeaderName files in mod_autoindex. Removed the restriction on
4008 "/"s in ReadmeName and HeaderName directives since the *sub_req*
4009 routines will deal with the access issues. (It's now possible to
4010 have {site|group|project|customer|...} wide readmes and headers.)

4025 by default when building with APACI; allow for platform-specific
4026 variable defaults in configure. [Wilfredo Sanchez]
4028 *) Do setgid() before initgroups() in http_main; some platforms
4029 zap the grouplist when setgid() is called. This was fixed in

4046 being newer than Configuration so that it is less likely to fail
4047 when using APACI and shadow sources. [Wilfredo Sanchez]
4049 *) PORT: Add initial support for Mac OS (versions 10.0 and
4050 greater). Use Mac OS X Server layout for now. Clean up dyld code
4051 in unix/os.c, and don't install the dyld error handlers, which
4052 are no longer needed in Mac OS. [Wilfredo Sanchez]
4054 *) Rename Rhapsody layout to "Mac OS X Server". Change install
4055 locations to appropriate ones for user-built (as opposed to
4056 system) installs. [Wilfredo Sanchez]
4058 *) Modify mod_autoindex's handling of AddDescription so that the
4059 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
4061 *) Add functionality to the install-bindist.sh script created by
4062 binbuild.sh to use tar when copying distribution files to the
4063 serverroot. This allows upgrading an existing installation
4064 without nesting the new distribution in the old.
4066 install-bindist.sh now detects the local perl5 path to install
4067 apxs and dbmmanage with proper path to perl interpreter.
4069 Add an install-binsupport target which copies the source files
4070 for apxs and dbmmanage to bindist to allow these scripts to
4071 be properly installed relative to the destination serverroot.

4187 *) Correct an apparent typo: on the Windows and MPE platforms, the
4188 htpasswd utility was limiting passwords to only 8 characters.
4191 *) EBCDIC platforms: David submitted patches for two bugs in the
4192 MD5 digest port for EBCDIC machines:
4193 a) the htdigest utility overwrote the old contents of the digest file
4194 b) the Content-MD5 header value (ContentDigest directive) was wrong
4195 when the returned file was not converted from EBCDIC, but was a
4196 binary (e.g., image file) in the first place.
4197 [David McCreedy <mccreedy@us.ibm.com>]
4199 *) support/htpasswd now permits the password to be specified on the
4200 command line with the '-b' switch. This is useful when passwords
4201 need to be maintained by scripts -- particularly in the Win32
4202 environment. [Ken Coar]
4204 *) Win32: Win32 multiple services patch. Added capability to install and
4205 run multiple copies of apache as individual services.
4208 apache -n apache1 -i -f c:/httpd.conf
4209 Installs apache as service 'apache1' and associates c:/httpd.conf

4235 mismatches were causing compilation problems with gcc -pedantic and

4238 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4239 a roughly 5 fold speed up. [Brian Havard]
4241 *) proxy ftp: instead of using the hardwired string "text/plain" as
4242 a fallback type for files served by the ftp proxy, use the
4243 ap_default_type() function to determine the configured type.
4244 This allows for special configurations like
4245 <Directory proxy:ftp://some.host>
4246 DefaultType gargle/blurb
4248 Additionally, add the Content-Encoding: header to FTP proxy replies
4249 when the encoding is defined (by the AddEncoding directive).
4250 Because it was missing, it was almost impossible to browse compressed
4251 files using the FTP proxy (works now perfectly in Communicator).
4252 The ftp proxy now also returns the Date: and Server: header lines (if not
4253 much else... This code is "somewhat" broken) like normal requests do.
4256 *) Be more smart in APACI's configure script when determining the UID/GID
4257 for User/Group directives and use the determined UID/GID to initialize
4258 the permissions on the proxycachedir.
4259 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4261 *) Changed the forking-prior-to-cleanup in the proxy module to first

4263 the number of fork()s from one/request to just the odd one an hour.
4264 [Dirk-Willem van Gulik]

4294 methods can be access controlled. [Roy Fielding] PR#3821
4296 *) Added PassAllEnv; makes server's entire environment available
4297 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4299 *) ap_uuencode() always added two trailing '='s and encoding of
4300 8 bit characters on a machine with signed char may produced
4301 incorrect results. Additionally ap_uuencode() should now
4302 work correctly on EBCDIC platforms.
4303 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4305 *) WIN32: Binary installer now runs the configuration DLL before
4306 the reboot prompt (which is only given if MSVCRT.DLL system
4307 DLL is new or updated). This should avoid the configuration
4308 directory being empty after installation. [Paul Sutton]

4332 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4333 for 8-bit safeness. [Dean Gaudet]
4335 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4336 because SPARCs have a small machine-specific maximum size for the Global
4337 Offset Table which is often exceeded when compiling one of the larger
4338 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4340 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

4364 *) Remove no longer used non-API function ap_single_module_init().
4365 [Ralf S. Engelschall]
4367 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4370 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4371 to make platform installations easier. [Wilfredo Sanchez]
4373 *) In configure, do not append the target name to the directory path if
4374 the path already contains "apache". [Ralf S. Engelschall]
4376 *) SIGPIPE is now ignored by the server core. The request write routines
4377 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4378 correctly check for output errors and mark the connection as aborted.
4379 Replaced many direct (unchecked) calls to ap_b* routines with the
4380 analogous ap_r* calls. [Roy Fielding]
4382 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4383 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4384 Furthermore map lookups for non-existent keys are now cached as well.
4385 Additionally "txt" maps are now parsed with simple string functions
4386 instead of using ap_pregcomp(). As a side effect a bug that prevented
4387 the usage of keys containing the "," character was fixed.
4388 The changes drastically improve the performance when large rewrite maps
4390 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

4398 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4399 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4401 *) Add %V to mod_log_config, this logs the hostname according to the
4402 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4403 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4405 *) Add support for \n and \t to mod_log_config, can be used to produce
4406 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4408 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]

4414 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4416 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4417 is removed. This allows <Directory proxy:*> directives to work and
4418 prevents invalid requests from killing the process.
4419 [Brian Havard <brianh@kheldar.apana.org.au>]
4421 *) Reorganised FAQ document.

4425 David N. Welton: you can now have it generate an HTML TABLE, presumably
4426 for integration into other HTML sources. David updated the ab man page
4427 as well and added some missing descriptions. Thanks!
4428 [David N. Welton <davidw@prosa.it>]
4430 *) Win32: The filename validity checker now allows filenames containing
4431 characters in the range 0x80 to 0xff (for example accented characters).
4432 [Paul Sutton] PR#3890
4434 *) Added conditional logging based upon environment variables to
4435 mod_log_config. mod_log_referer and mod_log_agent
4436 are now deprecated. [Ken Coar]
4438 *) Allow apache acting as a proxy server to relay the real
4439 reason of a failure to a client rather than the "internal
4440 server error" it does currently. The general exposure mechanism
4441 can be triggered by any module by setting the "verbose-error-to"
4442 note to "*"; this allows more than just proxy errors to be exposed.
4443 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4445 *) Moved man pages for ab and apachectrl to section 8.
4446 [Wilfredo Sanchez, Roy Fielding]
4448 *) Added -S option to install.sh so that options can be passed to
4449 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4451 *) Tweak modules Makefile generated by Configure so that it handles
4452 the test case of no modules being selected. [chaz@reliant.com]
4454 *) Added a <LimitExcept method ...> sectioning directive that allows
4455 the user to assign authentication control to any HTTP method that
4456 is *not* given in the argument list; i.e., the logical negation
4457 of the <Limit> directive. This is particularly useful for controlling
4458 access on methods unknown to the Apache core, but perhaps known by
4459 some module or CGI script. [Roy Fielding, Tony Finch]
4461 *) Prevent apachectl from complaining if the PIDFILE exists but
4462 does not contain a process id, as might occur if the server is
4463 being rapidly restarted. [Wilfredo Sanchez]
4465 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4467 *) Entity tag comparisons for If-Match and If-None-Match were not being
4468 performed correctly -- weak tags might cause false positives. Also,
4469 strong comparison wasn't properly enforced in all cases.
4470 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657

4475 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4476 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4478 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4479 to util.c for parsing an HTTP header field value to extract the next
4480 list item, taking into account the possible presence of nested comments,
4481 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4482 insignificant whitespace and lowercases non-quoted tokens.
4483 [Roy Fielding] PR#2065
4485 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4486 code different from 500. This allows the proxy to, e.g., return
4487 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4489 *) Fix ordering of language variants for the case where the traditional
4490 negotiation algorithm is being used with multiple language variants
4491 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4493 *) Do not round the TCN quality calculation to 5 decimal places,
4494 unlike RFC 2296, because the calculation might need 12 decimal places
4495 to get the right result. [Roy Fielding]
4497 *) Remove unused code to disable transparent negotiation when
4498 negotiating on encoding only, as we now handle encoding too
4499 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4500 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4501 some debugging statements within mod_negotiation. [Koen Holtman]
4503 *) Fixed a rare memory corruption possibility in mod_dir if the index
4504 file is negotiable and no acceptable variant can be found.
4505 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4507 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4508 searching the Win32 registry for script interpreters.
4511 *) Win32: The compiled-in default filename for the error log is now
4512 error.log, which matches the default in the distributed httpd.conf.
4515 *) Win32: Any error messages from -i or -u command line options are now
4516 displayed on the console output rather than sent to the error log.
4517 Also the "Running Apache..." message is not output unless Apache is
4518 going to serve requests. [Paul Sutton]
4520 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4521 and use a private significator ('$apr1$') to mark passwords as
4522 being smashed with our own algorithm. Also abstract the password
4523 checking into a new ap_validate_password() routine. [Ken Coar]
4525 *) Win32: The filename validity checker now allows "COM" but refuses
4526 access to "COM1" through "COM4". This allows filenames such
4527 as "com.name" to be served. [Paul Sutton] PR#3769.
4529 *) BS2000: Adapt to the new ufork() system call interface which will
4530 make subtasking easier on the OSD/POSIX mainframe environment.
4533 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4534 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4536 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4537 use `.db' instead of `.pag' not only for FreeBSD, but also when
4538 the NDBM library looks like Berkeley-DB based.
4539 [Ralf S. Engelschall] PR#3773
4541 *) Add ability to handle DES or MD5 authentication passwords.
4542 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4544 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4546 *) SECURITY: Avoid some buffer overflow problems when escaping
4547 quoted strings. (This overflow was on the heap and we believe
4548 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4550 *) Let src/Configure be aware of CFLAGS options starting with plus
4551 signs as it's the case for the HP/UX compiler.
4552 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4554 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4555 and check to see if the tar we wind up with supports '-h'.
4556 [Jim Jagielski] PR#3671
4558 *) A consistent and conservative style for all shell scripts has been
4559 implemented. Basically, all shell string tests use the traditional
4560 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4561 to protect against bare null variable strings (ie: wrapping both
4562 sides with double quotes and prepending 'x'). 'x' was chosen
4563 because it's more universal and hopefully easier for old shell
4564 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4567 *) The status module now prints out both the main server generation as
4568 well as the generation of each process. Also, the vhost info is
4569 printed with '?notable'. [Jim Jagielski]
4571 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4572 and this makes its functions available to things in src/support.
4575 Changes with Apache 1.3.4
4577 *) Renamed macros status_drops_connection to ap_status_drops_connection
4578 and vestigial scan_script_header to ap_scan_script_header_err,
4579 mostly for aesthetic reasons. [Roy Fielding]
4581 *) The query switch "httpd -S" didn't exit after showing the
4582 vhost settings. That was inconsistent with the other query functions.
4585 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4586 filename to the end of the STANDARD_MODULE_STUFF. Its
4587 presence at the beginning prevented reporting of the filename
4588 for modules compiled before 1 January 1999. [Ken Coar]
4590 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4591 to detect and prevent access to special DOS device file names.
4592 [Paul Sutton, Ken Parzygnat]
4594 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4595 and Makefile_win32_debug.txt (debug build) that work on Win95.
4596 Run each of the following from the src directory:
4597 nmake /f Makefile_win32.txt # compiles normal build
4598 nmake /f Makefile_win32.txt install # compiles and installs
4599 nmake /f Makefile_win32.txt clean # removes compiled junk
4600 nmake /f Makefile_win32_debug.txt # compiles debug build
4601 nmake /f Makefile_win32_debug.txt install
4602 nmake /f Makefile_win32_debug.txt clean
4605 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4606 to build binary distributions. [Lars Eilebrecht]
4608 *) IndexOptions SuppressColumnSorting only turned off making
4609 the column headers anchors; you could still change the display
4610 order by manually adding a '?N=A' or similar query string to the
4611 URL. Now SuppressColumnSorting locks in the sort order so
4612 it can't be overridden this way. [Ken Coar]
4614 *) Added IndexOrderDefault directive to supply a default sort order
4615 for FancyIndexed directory listings. [Ken Coar] PR#1699
4617 *) Change the ap_assert macro to a variant that works on all platforms.
4618 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4620 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4621 search for an underscore on dlsym() (as it's already the case
4622 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4624 *) Small fix for mod_env.html: The module was documented as to be _not_
4625 compiled into Apache per default, although it _IS_ compiled into
4626 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4628 *) Instead of fixing a bug in the generation procedure for config.status (a
4629 backslash was missing) we remove the bug together with it's complete
4630 context because the special cases of the past can now no longer occur
4631 because of the recent magic for the --with-layout default.
4632 [Ralf S. Engelschall] PR#3590
4634 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4635 making sure the src/support/ tools are _forced_ to be build last (they
4636 depend on other libraries).
4637 [Markus Theissinger <markus.theissinger@gmx.de>]
4639 *) Fix installation procedure: Now that os-inline.c is actually used (a
4640 recently fixed bug prevented this) we need to also install os-include.c
4641 in addition to os.h into the PREFIX/include/ location or building of
4642 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4644 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4645 allow us to distinguish between a garbled DSO (or even a file which isn't
4646 an Apache module DSO at all) and a DSO which doesn't match the current
4647 Apache API. [Ralf S. Engelschall] PR#3152
4649 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4650 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4651 match case insensitive (this especially avoids nasty patterns like
4652 `[tT][eE][sS][tT]'). Second two additional internal map functions
4653 `escape' and `unescape' were added which can be used to escape/unescape
4654 to/from hex-encodings in URLs parts (this is especially useful in
4655 combination with map lookups).
4656 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4658 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4659 forgotten (because it was a macro) in the symbol renaming process.
4660 [Ralf S. Engelschall]
4662 *) Fix some inconsistencies related to the scopes of directives. The only
4663 user visible change is that the directives `UseCanonicalName' and
4664 `ContentDigest' now use the (more correct) `Options' scope instead of
4665 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4667 *) Using DSO, the Server token was being mangled. Specifically, the
4668 module's token was being added first before the Apache token. This
4669 has been fixed. [Jim Jagielski]
4671 *) Major overhaul of mod_negotiation.c, part 2.
4672 - properly handle "identity" within Accept-Encoding.
4673 - allow encoded variants in RVSA negotiation and let them appear in
4674 the Alternates field using the non-standard "encoding" tag-list.
4675 - fixed both negotiation algorithms so that an explicitly accepted
4676 encoding is preferred over no encoding if "identity" is not
4677 included within Accept-Encoding.
4678 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4679 of large substring sequences.
4680 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4683 *) Major overhaul of mod_negotiation.c, part 1.
4684 - cleanups to mod_negotiation comments and code structure
4685 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4686 support for everything in the upcoming HTTP/1.1
4687 revision (draft-ietf-http-v11-spec-rev-06.txt).
4688 - language tag matching also handles tags with more than 2
4690 - empty Accept, Accept-Language, Accept-Charset headers are
4691 processed correctly; previously an empty header would make all
4692 values acceptable instead of unacceptable.
4693 - allowed for q values in Accept-Encoding
4694 - added support for transparent content negotiation (rfc2295 and
4695 rfc2296) (though we do not implement all features in these drafts,
4696 e.g. no feature negotiation). Removed old experimental version.
4697 - implemented 'structured entity tags' for better cache correctness
4698 (structured entity tags ensure that caches which can deal with Vary
4699 will (eventually) be updated if the set of variants on the server
4701 - this involved adding a vlist_validator element to request_rec
4702 - this involved adding the ap_make_etag() function to the global API
4703 - modified guessing of charsets used by Apache negotiation algorithm
4704 to guess 'no charset' if the variant is not a text/* type
4705 - added code to sort multiviews variants into a canonical order so that
4706 negotiation results are consistent across backup/restores and mirrors
4707 - removed possibility of a type map file resolving to another type map
4708 file as its best variant
4709 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4711 *) RFC2396 allows the syntax http://host:/path (with no port number)
4712 but the proxy disallowed it (ap_proxy_canon_netloc()).
4713 [David Kristol <dmk@bell-labs.com>] PR#3530
4715 *) When modules update/modify the file name in the configfile_t structure,
4716 syntax errors will report the updated name, not the original one.
4717 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
4719 *) Correct some filename case assumptions from WIN32 to
4720 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4722 *) For %v log ServerName regardless of the UseCanonicalName
4723 setting (similarly for %p). [Dean Gaudet]
4725 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4726 rather late (too late for some invocations of TestCompile).
4727 This improves the make environment available to TestCompile and
4728 the *.module scripts. [Martin Kraemer]
4730 *) The hashbang emulation code in ap_execve.c would interpret
4731 #!/hashbang/scripts correctly, but failed to fall back to a
4732 standard shell for scripts which did NOT start with #!
4733 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4735 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4738 *) Update APXS manual page: some -q option arguments were missing
4739 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4741 *) Cleanup the command line options: `-?' was documented to show
4742 the usage list but does it with an error because `?' is not a valid
4743 command. OTOH a lot of users expect `-h' to print such a usage list and
4744 instead are annoyed for ages by our huge unreadable list of directives.
4745 So we now changed the command line options this way:
4747 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4748 very similar to the popular linker option.
4750 Intent: while -l gives the small list of modules, -L now gives the
4751 large list of directives implemented by these modules. This is also
4752 consistent with -v (short version info) and -V (large version info).
4754 Intent: it's now the expected option ;-)
4755 The manual page was adjusted accordingly.
4756 [Ralf S. Engelschall] PR#2714
4758 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4759 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4761 *) Removed recently introduced bugs and disfigurements in APACI:
4762 o fixed argument line processing: using $args was broken: It was not
4763 initialized and using args="$args $apc_option" and even args="$args
4764 \"$apc_option\"" fails in the second processing round for any arguments
4765 containing whitespaces. The only correct way is to use the construct
4766 "$@" (but not possible here) or iterate _both_ times over the implicit
4767 argument line (no argument to for-loop) which is what we now use.
4768 o make --with-layout=Apache the default without creating
4769 redundancy (copying the --with-layout block in the argument parsing
4770 loop). We achieve this by using the "$@" construct together with the
4771 `set' command to prepend --with-layout=Apache to the command line in
4772 case --with-layout is not used.
4773 o fixed auto-suffix handling now that config.layout exists.
4774 Paths which are auto-suffixed are marked with a trailing plus sign in
4775 config.layout and every path now can be marked this way (not only the
4776 four paths for which we do it currently). Additionally the suffix is
4777 no longer a static one. Instead it's now `/<target>' where <target> is
4778 the argument of the --target option or per default `httpd'.
4779 o allow also tabs (and only spaces) where we match whitespaces
4780 o various fixes and cleanups related to used shell coding style
4781 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4782 o trimmed output of --help to fit into 80 columns
4783 [Ralf S. Engelschall]
4785 *) Added two new core API functions, ap_single_module_configure() and
4786 ap_single_module_init(), which are now used by mod_so to configure a module
4787 after loading. [Ralf S. Engelschall]
4789 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4790 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4791 of ap_config.h to allow serialized accept for multiport listens.
4792 [Roy Fielding, Curt Sampson] PR#3120
4794 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4795 of ap_config.h that would skip several defines if DEFAULT_GROUP
4796 was overridden. [Roy Fielding]
4798 *) PORT: The I86 version of DGUX has support for strncasecmp and
4799 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4801 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4802 defined before it might be used. [Victor Khimenko]
4804 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4805 [Tom Serkowski <tks@bsdi.com>] PR#3453
4807 *) Make generation of src/Configuration.apaci more robust: It failed to
4808 differenciate between modules when one module name was a postfix of
4809 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4810 just XXX (think about totally non-standard names like "apache_ssl", too).
4811 [Ralf S. Engelschall] PR#3380
4813 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4814 since 1.3b7) and make whitespace handling more robust (it failed horrible
4815 when whitespaces were present in the arguments of -D options).
4816 [Ralf S. Engelschall] PR#3240
4818 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4819 creates an external package shadow tree in DIR before the local build
4820 shadow tree is generated under DIR. This way one can have the extracted
4821 Apache distribution tree read-only on NFS or CDROM and still build Apache
4822 from these sources. An automatically triggered VPATH-like mechanism is
4823 provided through the TOP variable, too.
4824 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
4826 *) Fix negotiation so that a Vary response header is correctly
4827 generated when, for a particular dimension, variants only vary
4828 in having or not having a value for that dimension. [Paul Sutton]
4830 *) Fix negotiation so that we prefer an encoded variant over an
4831 unencoded variant if the user-agent explicitly says it can
4832 accept that encoding. Previously we always preferred the unencoded
4834 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4836 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4837 and the usage page was inconsistent with the functionality and manpage.
4838 [Ralf S. Engelschall]
4840 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4841 They can occur multiple times and their arguments (`xxx') are passed AS
4842 IS to the compiler/linker command. [Ralf S. Engelschall]
4844 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4845 procedure of mod_rewrite: very long keys were truncated.
4846 [Ralf S. Engelschall]
4848 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4849 identifier, currently "Apache" and "GNU" are pre-defined in the file
4850 config.layout. Custom layouts are possible by using FILE:ID as the
4851 argument where the layout ID is taken from FILE.
4853 The config.layout file consists of <Layout ID>..</Layout> sections
4854 where inside those sections "path_variable: path_value" pairs can be
4855 specified. These lines are converted to path_variable='path_value'.
4857 *) Add a DefaultLanguage directive so that files missing a language
4858 extension (e.g., .fr, .de) can be labelled as being some other
4859 default language. DefaultLanguage can appear in <Directory> and
4860 <Files> containers as well as .htaccess files. [Paul Sutton]
4863 *) Fix TARGET configuration when configuring and installing using
4864 APACI configure. TARGET now defines the basename of the configuration
4865 file, startup script, manual page, etc. log_error_core() now reports
4866 the server binary name given by argv[0]. TARGET can now also be defined
4867 with --target=TARGET parameter passed to APACI configure.
4868 [Ralf Engelschall, Randy Terbush]
4870 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4871 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

4975 in the Configuration[.apaci] file. Two special and important variants are
4976 supported for the option argument: first BEGIN:foo which permutes module
4977 mod_foo with the begin of the module list, i.e. it `moves' the module to
4978 the begin of the list (gives it lowest priority). And second foo:END
4979 which permutes mod_foo with the end of the module list, i.e. it `moves'
4980 the module to the end of the list (gives it highest priority).

4983 *) Fix problem with 'apache -k shutdown' and startup event
4984 synchronisation (Win32). [Ken Parzygnat <kparz@raleigh.ibm.com>]
4987 *) The config parser wasn't correctly noticing a missing '>'
4988 on container start lines (e.g., it wouldn't spot
4989 "<Directory /" as a syntax error). [Ryan Bloom <rbbloom@us.ibm.com>]
4992 *) Add a 'RemoveHandler' directive which will selectively remove
4993 all handler associations for the specified file extensions.

4996 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and
4997 ResourceConfig directives on Win32. Also add a note to the effect
4998 of 'useless User directive ignored on Win32' to the errorlog if
4999 a User directive is encountered on Win32.

5002 *) Fix multiple whitespace handling in imagemaps for mod_imap which was
5003 broken since Apache 1.3.1 where we took out compressing of multiple
5004 spaces in ap_cfg_getline().
5005 [Ivan Richwalski <ivan@seppuku.net>] PR#3249
5007 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
5008 initialized correctly and the db_open() call used an invalid mode
5009 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
5011 *) PORT: DSO support for UnixWare 7
5012 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
5014 *) Merge the contents of the {srm,access}.conf-dist* files into the
5015 httpd.conf-dist* files. The srm and access files now contain
5016 only comments, and httpd.conf has all the combined contents in
5017 a rational order. [Ken Coar]
5019 *) PORT: DSO/ELF support for FreeBSD 3.0.
5020 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
5022 *) Add a "default-handler" handler that calls the default_hander()
5023 function which is normally called for static content. This allows
5024 you to override a specific handler. [Marc Slemko]
5026 *) Further simplify checking for absolute paths by replacing an
5027 hard-coded syntax check with a call to a routine we already created to
5028 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
5030 *) Log an error if we encounter a malformed "require" directive
5031 in mod_auth if we know that we know that no other module can
5032 deal with it. [Marc Slemko]
5034 *) Remove ap_private_extern method of hiding conflicting symbols
5035 on the NEXT platform because it is not correct for all versions,
5036 and the versions for which it is correct are unknown.
5037 [Wilfredo Sanchez <wsanchez@apple.com>]
5039 *) Fix inheritance of IndexOptions NameWidth and remove unintended
5040 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]

5043 is encountered in an .htaccess file somewhere down the tree.
5046 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
5048 *) Fixed a segmentation violation in mod_proxy when a response is
5049 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
5051 Changes with Apache 1.3.3
5053 *) Added a complete implementation of the Expect header field as
5054 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
5055 response when we already know the final status, which is mighty
5056 useful for PUT responses that result in 302 or 401. [Roy Fielding]
5058 *) Remove extra trailing whitespace from the getline results as part
5059 of the protocol processing, which is extra nice because it works
5060 between continuation lines, is almost no cost in the normal case
5061 of no extra whitespace, and saves memory. [Roy Fielding]
5063 *) Added new HTTP status codes and default response bodies from the
5064 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
5065 HTTP Extension Framework (510) specifications. Did not add the
5066 WebDAV 424 and 425 codes because they are bogus. We don't use any
5067 of these codes yet, but they are now available to 3rd-party modules.
5070 *) Fix a possible race condition between timed-out requests and the
5071 ap_bhalfduplex select that might result in an infinite loop on
5072 platforms that do not validate the descriptor. [Roy Fielding]
5074 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
5075 running Apache server [Paul Sutton]
5077 *) Fix mod_autoindex bug where directories got a size of "0k" instead
5078 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
5081 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]

5084 to the list of envariables available to scripts, SSI, and the like.
5087 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
5088 [M. Laak <maert@proinv.ee>] PR#3108
5090 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
5091 calculation in mod_status for all systems which don't have POSIX
5092 sysconf() (like UTS 2.1) and not only for the NEXT platform.

5095 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
5096 mod_auth_db by using ap_getword_white() (which uses ap_isspace())

5098 but not tabs). [James Morris <jmorris@intercode.com.au>,

5142 *) Reconstructed the loop through multiple htaccess file names so
5143 that missing files are not confused with unreadable files.
5146 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
5147 errno on an error, which leads to one error being mistaken for

5169 Changes with Apache 1.3.2
5171 *) Fix bug in ap_remove_module(), which caused problems for dso's
5172 who were the top_module. [Doug MacEachern]
5174 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
5175 mod_auth_db to both be friendly to users who wants to use this version
5176 and to avoid problems under platforms where only version 2.x is present.
5177 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
5179 *) When using ap_log_rerror(), make the error message available to the
5180 *ERROR_NOTES envariables by default. [Ken Coar]
5182 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
5183 You now must define a BS2000Account name for the server User.
5184 This has fewer security implications than the old approach.
5187 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
5188 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
5189 platform to make the braindead HPUX linker happy. Notice, for the module
5190 DSOs we don't have to use this, because these are loaded manually (and
5191 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
5193 *) Remove 64 thread limit on Win32.
5194 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5196 *) Remove redundant substitutions in top-level Makefile.tmpl.
5197 [Ralf S. Engelschall]
5199 *) Fix APACI's `Group' configuration adjustment - especially for Linux
5200 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
5202 *) Make PrintPath work generically instead of having one version
5203 strictly for OS/2. [Jim Jagielski, Brian Havard]
5205 *) Fix the recently introduced C header file checking: We now use the C
5206 pre-processor pass only (and no longer the complete compiler pass) to
5207 determine whether a C header file exists or not. Because only this way
5208 we're safe against inter-header dependencies (which caused horrible
5209 portability problems). The only drawback is that we now have a CPP
5210 configuration variable which has to be determined first (we do a similar
5211 approach as GNU Autoconf does here). When all fails the user still has
5212 the possibility to override it manually via APACI or src/Configuration.
5213 As a fallback for the header check itself we can directly check the
5214 existance of the file under /usr/include, too.
5215 [Ralf S. Engelschall] PR#2777
5217 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
5218 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
5219 ap_private_extern defined to hide symbols that conflict with loaded
5220 dynamic libraries on the NEXT and RHAPSODY platforms.

5239 used -lprot. It's actually a bug in SCO5, of course.

5242 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
5243 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
5245 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
5246 platform, because it's only supported under version 4.0 and higher. But
5247 because our GuessOS is still unaware of Digital UNIX versions and the
5248 -msym is just to optimize the DSO statup time a little bit it's safe and
5249 best when we leave it out now. [Ralf S. Engelschall] PR#2969
5251 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
5252 functions: First all three functions no longer fail on strings containing
5253 "%" chars and second ap_log_printf() no longer does a double-formatting
5254 (instead it directly passes through the message to be formatted to the
5255 real internal formatting function). [Ralf S. Engelschall] PR#2941
5257 *) Allow "Include" directives anywhere in the server config
5258 files (but not .htaccess files). [Ken Coar] PR#2727
5260 *) The proxy was refusing to serve CONNECT requests except to
5261 port 443 (https://) and 563 (snews://). The new AllowCONNECT
5262 directive allows the configuration of the ports to which a
5263 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5265 *) mod_expires will now act on content that is not sent from a file
5266 on disk. Previously it would never add an Expires: header to
5267 any response that did not come from a file on disk; the only
5268 case where it still doesn't (and can't) add one for that type of
5269 content is if you are using a modification date based setting.
5270 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
5272 *) Problems encountered during .htaccess parsing or CGI execution
5273 that lead to a "500 Server Error" condition now provide explanatory
5274 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
5277 *) Add NameWidth keyword to IndexOptions directive so that the
5278 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
5281 *) Recognize lowercase _and_ uppercase `uname' results under
5282 SCO OpenServer. [David Coelho <drc@ppt.com>]
5284 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5285 a common problem of (mis-administrated?) IIS servers, make the apache
5286 proxy immune to these errors (and ignore the duplicates, but log
5287 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5289 *) The <IfModule and <IfDefine block starting directives now only
5290 allow exactly one argument. Previously, the optional negation
5291 character '!' could be separated by whitespace without a syntax
5292 error being reported, albeit defeating the IfModule functionality
5293 (enclosed directives would ALWAYS be executed). By using the
5294 stricter syntax, these hard-to-track errors can be avoided.
5297 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5298 cause the standalone FancyIndexing directive to logically OR
5299 into any existing IndexOptions settings rather than wiping
5300 them out. [Ken Coar]
5302 *) Changes in ftp proxy: make URL parsing simpler by using the
5304 + Add display of the "current directory" in cases where it's
5305 different from the supplied path (e.g., ftp://user@host/ lives
5306 in /home/user, not in /, therefore clicking on "../" in the
5307 starting directory might send us to /home/).
5308 + When ftp login fails, (esp. when a user name was part of the
5309 URL already), we now return [401 Unauthorized ] to allow the
5310 browser to pop up an authorization dialog. This makes passwords
5311 slightly less visible (they don't appear in the regular log files)
5312 and implements a functionality that other www proxy servers
5316 *) Triggered by the recent "Via:" header changes, the proxy module would
5317 dump core for replies with invalid headers (e.g., duplicate
5318 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5319 core dump is avoided. Also, broken replies are not cached.
5320 [Martin Kraemer] PR#2914
5322 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
5323 plop gmon.out profile data for each child [Doug MacEachern]
5325 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
5326 config.status script to be immune against arguments with whitespaces.
5327 [Yves Arrouye <yves@apple.com>] PR#2866
5329 *) Replace the inlined information grabbing stuff for the configuration
5330 adjustment feature (no --without-confadjust) with calls to a new helper
5331 script `buildinfo.sh' which is both more flexible and already proofed to
5332 be more robust against platform differences. This mainly fixes the
5333 recently occured ``sed: command garbled: ...'' problems.
5334 [Ralf S. Engelschall] PR#2776, PR#2848
5336 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
5337 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
5338 without complains after we recently added the POST feature.
5339 [Ralf S. Engelschall]
5341 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
5342 modules as API functions and we forgot them at the big symbol renaming.
5343 [Ralf S. Engelschall]
5345 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

5351 *) Add the ability to do POST requests to the ab benchmarking tool.
5352 [Kurt Sussman <kls@best.com>] PR#2871
5354 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5355 5 to 10 because there are some users out there who always have 5 to 8
5356 variables in one RewriteRule and had to patch mod_rewrite.h for every
5357 release. So 15 should be now more than enough, even for them. (I never
5358 needed more than 4 in my RewriteRules ;-)
5359 [Ralf S. Engelschall]
5361 *) Make the proxy generate and understand Via: headers
5364 *) Change the proxy to use tables instead of array_headers for
5365 the header lines. [Martin Kraemer]
5367 *) Make sure the config.status file is not overridden when just
5368 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
5370 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
5371 provide a way to trace API changes that add functionality but do
5372 not create a compatibility issue for precompiled modules, etc.
5373 See include/ap_mmn.h for more details. [Randy Terbush]
5375 *) Fix suexec installation under `make install root=xxx' situation.
5376 [Ralf S. Engelschall]
5378 *) Extend the output of the -V switch to include the paths of all
5379 compiled-in configuration files, if they were overridden at
5380 compile time, for least astonishment of the user.
5383 *) When READing a request in ExtendedStatus mode, the "old"
5384 vhost, request and client information is not displayed.
5387 *) STATUS is no longer available. Full status information now
5388 run-time configurable using the ExtendedStatus directive.
5391 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5392 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5393 a function which can be used to perform bulk update operations
5394 on tables in a more efficient manner. [Dean Gaudet]
5396 *) SECURITY: Added compile-time and configurable limits for
5397 various aspects of reading a client request to avoid some simple
5398 denial of service attacks, including limits on maximum request-line
5399 size (LimitRequestLine), number of header fields (LimitRequestFields),
5400 and size of any one header field (LimitRequestFieldsize). Also added
5401 a configurable directive LimitRequestBody for limiting the size of the
5402 request message body. [Roy Fielding]
5404 *) Make status module aware of DNS and logging states, even if
5405 STATUS not defined. [Jim Jagielski]
5407 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
5409 *) Enhance mod_speling so that CheckSpelling can be used in
5410 <Directory> containers and .htaccess files. [Ken Coar]
5412 *) API: new ap_custom_response() function for hooking into the
5413 ErrorDocument mechanism at runtime [Doug MacEachern]
5415 *) API: new ap_uuencode() function [Doug MacEachern]
5417 *) API: scan_script_header_err_core() now "public" and renamed
5418 ap_scan_script_header_err_core() [Doug MacEachern]
5420 *) The 'status' module will now show the process pid's and their
5421 state even without full STATUS accounting. [Jim Jagielski]
5423 *) Restore the client IP address to the error log messages, this
5424 was lost during the transition from 1.2 to 1.3. Add a new
5425 function ap_log_rerror() which takes a request_rec * and
5426 formats it appropriately. [Dean Gaudet] PR#2661
5428 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5429 whitespace in input lines -- including within quoted strings.
5431 but leading and trailing whitespace should continue to be
5432 stripped [Martin Kraemer]
5434 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5435 the ugly use of an env. variable and use command-line args for
5436 alternate $PATH. Make more like advanced 'type's as well.
5439 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
5440 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
5441 <alain.st-denis@ec.gc.ca>] PR#2736
5443 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
5445 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
5446 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
5447 directory was renamed to src/os/os2/ for consistency.
5448 [Brian Havard, Ralf S. Engelschall]
5450 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5451 files (here modules) against other DSO files (here shared libraries).
5452 This is done by determining a subset of LIBS which can be safely used for
5453 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5454 disabled for all platforms to avoid problems with this (experimental)
5455 rule. But we provide it now for those people how ran into problems and
5456 want to came out by forcing linking against DSOs.
5457 [Ralf S. Engelschall] PR#2587
5459 *) Fix suEXEC start message: Has to be of `notice' level to really get
5460 printed together with the standard startup message because the `notice'
5461 level is handled special inside ap_log_error() for startup messages.

5470 *) Allow ap_read_request errors to propagate through the normal request
5471 handling loop so that the connection can be properly closed with
5472 lingering_close, thus avoiding a potential TCP reset that would
5473 cause the client to miss the HTTP error response. [Roy Fielding]
5475 *) One more portability fix for APACI shadow tree support: Swap order of awk
5476 and sed in top-level configure script to avoid sed fails on some

5761 in top-level configure script to avoid sed fails on some platforms (for

5763 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5765 *) Improve performance of directory listings (mod_autoindex) by comparing
5766 integer keys (last-modified and size) as integers rather than converting
5767 them to strings first. Also use a set of explicit byte tests rather
5768 than strcmp() to check for parent directory-ness of an entry. Oh, and
5769 make sure the parent directory (if displayed) is *always* listed first
5770 regardless of the sort key. Overall performance winnage should be good
5771 in CPU time, instruction cache, and memory usage, particularly for large
5772 directories. [Ken Coar]
5774 *) Add a tiny but useful goody to APACI's configure script: The generation
5775 of a config.status script (as GNU Autoconf does) which remembers the used
5776 configure command and hence can be used to restore the configuration by
5777 just re-running this script or for remembering the configuration between
5779 [Ralf S. Engelschall]
5781 *) Add httpd -t (test) option for running configuration syntax tests only.
5782 If something is broken it complains and exits with a return code
5783 non-equal to 0. This can be used manually by the user to check the Apache
5784 configuration after editing and is also automatically used by apachectl
5785 on (graceful) restart command to make sure Apache doesn't die on restarts
5786 because of a configuration which is now broken since the last (re)start.
5787 This way `apachectl restart' can be used inside cronjobs without having
5788 to expect Apache to be falling down. Additionally the httpd -t can be run
5789 via `apachectl configtest'.

5946 its error text using this variable. Its content is copied to a new
5947 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.

5973 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252
5975 *) Fix src/support/httpd.exp (DSO export file which is currently only
5976 used under AIX) because of recent changes to function names.
5977 [Ralf S. Engelschall]
5979 Changes with Apache 1.3b7
5981 *) Make sure a MIME-type can be forced via a RewriteRule even when no
5982 substitution takes place, for instance via the following rule:
5983 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
5984 requested by users in the past to force a single script without a .cgi
5985 extension and outside any cgi-bin dirs to be executed as a CGI program.
5986 [Ralf S. Engelschall] PR#2254
5988 *) A fix for protocol issues surrounding 400, 408, and
5989 414 responses. [Ed Korthof]
5991 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
5993 *) Fix discrepancy in proxy_ftp.c which was causing failures when
5994 trying to connect to certain ftpd's, such as anonftpd.
5995 [Rick Ohnemus <rick@ecompcon.com>]
5997 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
5998 logfile instead of fiddling around itself with child spawning stuff.
5999 [Ralf S. Engelschall]
6001 *) Made RefererIgnore case-insensitive.
6003 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
6006 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
6007 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
6010 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
6012 *) Fix support script `dbmmanage': It was unable to handle some sort
6013 of passwords, especially passwords with "0" chars.
6014 [Ralf S. Engelschall] PR#2242
6016 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
6017 [Ben Laurie] PR#2238
6019 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
6020 library), so CGI handling has been changed to use Win32 native handles
6021 instead of C file descriptors.
6022 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
6024 *) The proxy cache would store an incorrect content-length in the cached
6025 file copy after a cache update. That resulted in repeated fetching
6026 of the original copy instead of using the cached copy.
6027 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
6029 *) The Makefiles assumed that DSO files are build via $(LD). This
6030 is broken for two reasons: First we never defined at least LD=ld
6031 somewhere to make sure this works (it was silently assumed that most Make
6032 provide a built-in LD definition - ARGL!) and second using the generic LD
6033 variable is not the truth. Instead a special variable named LD_SHLIB is
6034 reasonable because although "ld" is usually the default, the command for
6035 building DSO files can be "libtool" or even "cc" on some systems.
6036 [Ralf S. Engelschall]
6038 *) Replace the AddVersionPlatform directive with ServerTokens which
6039 provides for more control over the format of the Server:
6040 header line. SERVER_SUBVERSION is no longer supported;
6041 all module should use the ap_add_version_component()
6042 API function instead. [Jim Jagielski]
6044 *) Support for the NCR MP/RAS 3.0
6045 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
6047 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
6048 not retrieved in src/Configure and thus was not useable.
6049 [Ralf S. Engelschall]
6051 *) Various Makefile consistency cleanups:
6052 - make OSDIR also automatically be relative to src/ like INCDIR
6053 - SUBDIRS is now generated in src/Makefile only and not in
6054 Makefile.config because it is a local define for this location.
6055 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
6056 any Makefile but make sure that at least the "-K inline" is kept in
6058 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
6059 - updated the dependencies theirself
6060 - removed not existing SHLIB variable from "clean" targets
6061 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
6062 already exists and OBJS_PIC are also just plain objects and have not
6063 directly to do with "shared" things. The only difference is that they
6064 contain PIC. So OBJS_PIC is the more canonical name.
6065 - Updated the Makefile-dependency lines for OBJS_PIC
6066 - Removed the Makefile-dependency line in Configure to avoid double
6068 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
6069 of xxx.lo as GNU libtool does with its PIC objects
6070 - reduce local complexity in modules Makefile.tmpl by moving the last
6071 existing target "depend" to the generation section in Configure, too.
6072 - removed the historical $(SPACER) which was used in the past together
6073 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
6074 is no longer needed.
6075 - force the build and run of the gen_xxx programs under main/ as the
6076 first step before building the objects because it looks cleaner
6077 [Ralf S. Engelschall]
6079 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
6082 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
6085 *) WIN32: Don't force ISAPI headers to finish with \n.
6086 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
6088 *) When opening "configuration" files (like httpd.conf, htaccess
6089 and htpasswd), Apache will not allow them to be non-/dev/null
6090 device files. This closes a DoS hole. At the same time,
6091 we use ap_pfopen to open these files to handle timeouts.
6092 [Jim Jagielski, Martin Kraemer]
6094 *) Apache will now log the reason its httpd children exit if they exit
6095 due to an unexpected signal. (It requires a new porting define,
6096 SYS_SIGLIST, which if defined should point to a list of text
6097 descriptions of the signals available. See PORTING.) [Dean Gaudet]
6099 *) WIN32: chdir() doesn't make sense in a multithreaded environment
6100 like WIN32. Before, Win32 CGI's could have had sporadic failures
6101 if a chdir call from one thread was made between another chdir call
6102 and a spawn in another thread. So, for now don't chdir for CGI scripts
6103 in WIN32. The current CGI "spec" is unclear as to whether it's
6104 necessary. Long-term fix is to either serialize the chdir/spawn combo
6105 or use WIN32 native calls to spawn a process. This temp fix was
6106 necessary to remove this as a showstopper for 1.3's release.
6109 *) Cleanup the suEXEC support in APACI and make it more safe:
6110 1. Add big fat hint in INSTALL about risks and to read the
6111 htdocs/manual/suexec.html document before using the suexec-related
6113 2. Make sure the user has at least provided one --suexec-xxxx option
6114 (specifies suEXEC parameters) in addition to --enable-suexec option.
6115 If only --enable-suexec is given APACI stops with a hint to INSTALL
6116 and htdocs/manual/suexec.html documents.
6117 3. Provide two additional --suexec-xxxx options to make the suEXEC
6118 configuration complete (especially for package maintainers who else
6119 had to patch the source tree) by providing ways to configure minimal
6120 UID/GID and safe PATH, too.
6121 [Ralf S. Engelschall]
6123 *) Cleanup of the `configure --shadow' process:
6124 - make sure the configure script creates its temporary files in the
6125 shadow tree to avoid conflicts with parallel configure runs
6126 - removed unnecessary option "-r" from "rm" call for Makefiles
6127 - make sure the configure scripts creates the shadow-wrapper Makefile
6128 only when no shadow trees already exists
6129 - make sure "make distclean" removes the shadow-wrapper Makefile but only
6130 when no more shadow trees exists
6131 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
6132 as fast (in the past it needed 70sec, now it runs just 38sec)
6133 - make sure CVS does not complain about the created files
6134 Makefille.<gnutriple> and directories src.<gnutriple>
6135 [Ralf S. Engelschall]
6137 *) Added the ap_add_version_component() API routine and the
6138 AddVersionPlatform core directive. The first allows modules to
6139 declare themselves in the Server response header field value,
6140 augmenting the SERVER_SUBVERSION define in the Configuration file
6141 with run-time settings (more useful in a loadable-module environment).
6142 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
6143 into the server version string. [Ken Coar] PR#2056
6145 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
6148 *) Emit the "Accept-Range" header for the default handler.
6149 [Brian Behlendorf] PR#1464
6151 *) Add a note to httpd.conf-dist that apache will on some systems fail
6152 to start when the Group # is set to a negative or large positive value.
6155 *) Make sure the module execution order is correct even when some modules
6156 are loaded under runtime (`LoadModule') via the DSO mechanism:
6157 1. The list of loaded modules is now a dynamically allocated one
6158 and not the original statically list from modules.c
6159 2. The loaded modules are now correctly setup by LoadModule for
6160 later use by the AddModule command.
6161 3. When the DSO mechanism for modules is used APACI's `install'
6162 target now enables all created `LoadModule' lines per default because
6163 this is both already expected by the user _and_ needed to avoid
6164 confusion with the next point and reduces the Makefile.tmpl complexity
6165 4. When the DSO mechanism for modules is used, APACI's `install'
6166 target now additionally makes sure the module list is reconstructed
6167 via a complete `ClearModuleList+AddModule...' entry.
6168 5. The support tool `apxs' now also makes sure an AddModule command
6169 is added in addition to the LoadModule command.
6170 6. The modules.c generation was extended to now contain two
6171 comments to make sure no one is confused by the confusing terminology
6172 of loading/linking (we use load=link+load & link=activate instead of
6173 the obvious load=activate & link=link :-( )
6174 This way now there is no longer a difference under execution time between
6175 statically and dynamically linked modules.
6176 [Ralf S. Engelschall]
6178 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
6179 Big Symbol Renaming. [Ralf S. Engelschall]
6181 *) Add a comment to mod_example.c showing the format of a FLAG command
6184 *) Standardized the time format in mod_status to match that of other
6185 places in the code (e.g. DATE_GMT). PR#1551
6187 *) Fix handling of %Z in timefmt strings for those platforms with no time
6188 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
6191 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
6192 feature compatible with 'UseCanonicalName off' by changing
6193 r->server->server_hostname to ap_get_server_name(). And I changed some
6194 functions which use r->server->port to use ap_get_server_port() instead,
6195 because if there's no Port directive in the config r->server->port is 0.
6198 *) get/set_module_config are trivial enough to be better off inline. Worth
6199 1.5% performance boost. [Dean Gaudet]
6201 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
6202 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
6205 *) [BS2000 security] BS2000 needs an extra authentication to initialize
6206 the task environment to the unprivileged User id. Otherwise CGI scripts
6207 would have a way to gain super user access. [Martin Kraemer]
6209 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
6210 absolute path, only log base name of logging source as is done
6211 in unix. [Martin Kraemer]
6213 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6214 the encoding type from the Accept-Encoding header (if it's there)
6215 and use it in the response, as that's probably what it'll be expecting.
6216 [Ronald.Tschalaer@psi.ch]
6218 *) Fix to mod_alias: translate_alias_redir is dealing with
6219 a URI, not a filename, so the check for drive letters for win32
6220 and emx is not necessary. [Dean Gaudet]
6222 *) WIN32: Allow .cmd as an executable extension.
6223 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
6225 *) Make Apache header files, and some variables, C++ friendly.
6226 [Michael Anderson's <mka@redes.int.com.mx>]
6228 *) Child processes can now "signal" (by exiting with a status
6229 of APEXIT_CHILDFATAL) the parent process to abort and
6230 shutdown the server if the error in the child process was
6231 fatal enough. [Jim Jagielski]
6233 *) mod_autoindex's find_itme() was sensitive to MIME type case.
6234 [Jim Jagielski] PR#2112
6236 *) Make sure the referer_log and agent_log entries in the default httpd.conf
6237 file are also adjusted for the actual relative installation paths.
6238 [Ralf S. Engelschall] PR#2175
6240 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
6242 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
6245 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6246 Additionally the checks for finding the vendor DSO library were moved
6247 from mod_so.c to Configure because first it needs $PLAT etc. and second
6248 mod_so already uses an abstraction layer and does not fiddle with the
6249 vendor functions itself.
6250 [Jens-Uwe Mager, Ralf S. Engelschall]
6252 *) PORT: Some optimization defines for NetBSD
6253 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6255 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6256 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6258 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6259 AIX variants should work fine, too. Even AIX 3.x should work). This is
6260 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6261 which we put into a os/unix/os-dso-aix.c file.
6262 [Ralf S. Engelschall]
6264 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6265 that we should use NET_SIZE_T == int but the include files force size_t.
6266 [Ralf S. Engelschall]
6268 *) Fix two bugs in select() handling in http_main.c.
6271 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6272 is unset (as it is in situations like timeouts) where it is unclear
6273 whether errno is set or not. [Martin Kraemer]
6275 *) Just having APACI's localstatedir is too general and not enough for most
6276 of the systems. 1.3b6 again required manual APACI patches by package
6277 maintainers from RedHat and FreeBSD because for their filesystem layout a
6278 little bit more flexibility in configuring the paths is needed. Hence we
6279 provide three additional configure options (--runtimedir, --logfiledir,
6280 --proxycachedir) which now can be used for more granular adjustments if
6281 --localstatedir is not enough to fit the particular needs. As a nice
6282 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6283 [Ralf S. Engelschall]
6285 *) Make the install root for "make install" in APACI's Makefile overrideable
6286 by package authors. This way we are even more friendly to package
6287 maintainers (especially Debian and RedHat) who build for the real prefix
6288 via "configure --prefix=/<real>" but use a different local prefix via
6289 "make root=/tmp/apache install" for rolling the package without bristling
6290 the target location on their system.
6291 [Ralf S. Engelschall]
6293 *) Workaround sed limitations in APACI's configure script by now
6294 substituting in chunks of 50 commands (because for instance HPUX's vendor
6295 sed has a limit of max. 98 commands)
6296 [Ralf S. Engelschall] PR#2136
6298 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
6299 [Ralf S. Engelschall] PR#2140
6301 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6302 RENAMING process because they are defined as pre-processor macros instead
6303 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6304 [Ralf S. Engelschall]
6306 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6307 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6308 [Ralf S. Engelschall] PR#2139
6310 *) Various bugfixes and cleanups for the APACI configure script:
6311 o fix IFS handling for _nested_ situation
6312 o fix Perl interpreter search: take first one found instead of last one
6313 o fix DSO consistency check
6314 o print error messages to stderr instead of stdout
6315 o add install-quiet for --shadow situation to Makefile stub
6316 o reduce complexity by avoiding sed-hacks for rule and module list loops
6317 [Ralf S. Engelschall]
6319 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6321 *) Make sure the input field separator (IFS) shell variable is explicitly
6322 initialized correctly before _every_ `for' loop and also restored after
6323 the loops. [Ralf S. Engelschall]
6325 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6326 `magic' files from an existing Apache installation. Because people often
6327 customize these for own MIME and content types.
6328 [Ralf S. Engelschall]
6330 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
6331 [Peter Galbavy, Ralf S. Engelschall] PR#2109
6333 *) Fix the path to the ScoreBoardFile in the install-config target, too.
6334 [Ralf S. Engelschall] PR#2105
6336 *) Let "configure" clear out the users parameters (provided as shell
6337 variables) to avoid side-effects in "src/Configure" when the user
6338 exported them (which is not needed, but some users do it).
6339 [Ralf S. Engelschall] PR#2101
6341 *) Provide backward compatibility from some old src/Configuration.tmpl
6342 parameter names to the canonical Autoconf-style shell variable names. For
6343 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
6344 but a hint message is displayed. [Ralf S. Engelschall]
6346 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
6347 CGI scripts from an existing Apache installation.
6348 [Ralf S. Engelschall, Jim Jagielski] PR#2084
6350 *) Make `configure --compat' more "compatible" by first
6351 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
6352 second by making sure the "avoid-bristling-suffix" /apache is not
6353 appended to sysconfdir, datadir, localstatedir and includedir when
6354 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
6356 *) NeXT required strdup() in support/logresolve.c
6357 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
6359 *) AIX required sys/select.h in support/ab.c
6360 [Jens Schleusener <Jens.Schleusener@dlr.de>] PR#2081
6362 *) Fix the path to the MimeMagicFile in the install-config target, too.
6363 [Ralf S. Engelschall] PR#2089
6365 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6367 *) If you start apache with the -S command line option it will dump
6368 out the parsed vhost settings. This is useful for folks trying
6369 to figure out what is wrong with their vhost configuration.
6370 (Other dumps may be added in the future.) [Dean Gaudet]
6372 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6373 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6376 *) Because /usr/local/apache is the default prefix the ``configure
6377 --compat'' option no longer has to set prefix, again. This way the
6378 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6380 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6381 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6382 to avoid "discard const" warnings. [Ralf S. Engelschall]
6384 *) If a specific handler is set for a file yet the request still
6385 ends up being handled by the default handler, log an error
6386 message before handling it. This catches things such as trying
6387 to use SSIs without mod_include enabled. [Marc Slemko]
6389 *) Fix error logging for the startup case where ap_log_error() still uses
6390 stderr as the target. Now the default log level is honored here, too.
6391 [Ralf S. Engelschall]
6393 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
6394 long" errors when generating the MODULES entry for src/Makefile
6395 [Ben Hyde, Ralf S. Engelschall]
6397 *) Make sure src/Configure doesn't complain about the old directory
6398 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6400 Changes with Apache 1.3b6
6402 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6404 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6405 interface via the similar but proprietary HP/UX shl_xxx-style system
6406 calls. [Ralf S. Engelschall]
6408 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6409 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6410 Make. [Ralf S. Engelschall]
6412 *) ++++ THE BIG SYMBOL RENAMING ++++
6413 To avoid symbol clashes with third-party code compiled into the server,
6414 we globally applied the prefix "ap_" to the following classes of
6416 - Apache provided general functions (e.g., ap_cpystrn)
6417 - Public API functions (e.g., palloc, bgets)
6418 - Private functions which we can't make static (because of
6419 cross-object usage) but should be (e.g., new_connection)
6420 For backward source compatibility a new header file named compat.h was
6421 created which provides defines for the old symbol names and can be used
6422 by third-party module authors.
6425 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6426 problem under SVR4 is that there is no command flag to force the linker
6427 to export the global symbols of the httpd executable therewith they are
6428 available to the DSO's. Instead of problematic hacks like creating a
6429 dummy.so file (containing dummy references to all global symbols) the
6430 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6431 Placing the Apache core code itself into a DSO library named libhttpd.so.
6432 This way the global symbols _HAVE_ to be exported and thus are available
6433 to any manually loaded DSO's under runtime. To reduce the impact to the
6434 user to null we go even further and create a stub httpd executable which
6435 automatically keeps track of the DSO library loading itself and thus
6436 hides the complete mechanism from the user. Although the generation of
6437 this DSO library is automatically triggered for platforms which
6438 essentially need it (mostly all SVR4-derivates) it can be also enabled
6439 manually via the Rule SHARED_CORE. This can be interesting in the future
6440 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6441 features like graceful upgrades, or whatever.
6442 [Ralf S. Engelschall, Martin Kraemer]
6444 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6446 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6447 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6448 conventions while "clean" removes only stuff created by "all" targets,
6449 "distclean" additionally removes the stuff from the configuration
6450 process. This way "make distclean" (hence the name) provides a fresh
6451 source tree as it was for distribution.
6452 [Ralf S. Engelschall]
6454 *) Allow top-level (APACI) Makefile to break on build errors
6455 the same way the src/ subtree Makefiles breaks on them by replacing the
6456 initial APACI sed-subdir-display-kludge with a more clean
6457 variable-passing-solution: variable SDP can optionally hold the subdir
6458 prefix which is consistently used for displaying the subdir movement.
6459 This way even the top-level Makefile can stop correctly on errors as the
6460 user expects. [Ralf S. Engelschall]
6462 *) Fixed ordering of argument checks for RewriteBase directive.
6463 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6465 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6466 indicating that a module is being compiled for dynamic loading. Also
6467 remove #define IS_MODULE from modules and add SHARED_MODULE define
6468 to the mak/dsp files. [Alexei Kosut]
6470 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6471 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6473 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6475 *) Add documentation file and src/Configuration.tmpl entry for the
6476 experimental mod_mmap_static module. Because although it is and marked as
6477 an experimental one it is distributed and thus should be documented and
6478 prepared for configuration the same way as all others modules.
6479 [Ralf S. Engelschall]
6481 *) Add query (-q) option to apxs support tool to be able to manually query
6482 specific settings from apxs. This is needed for instance when you
6483 manually want to access Apache's header files and you need to assemble
6484 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6485 [Ralf S. Engelschall]
6487 *) Now src/Configure uses a fallback strategy for the shared object support
6488 on platforms where no explicit information is available: If a Perl
6489 installation exists we ask it about its shared object support and if it's
6490 the dlopen-style one we shamelessly guess the compiler and linker flags
6491 for creating shared objects from Perls knowledge. Of course, the user is
6492 warning about what we are doing and informed that he should send us
6493 the guessed flags when they work. [Ralf S. Engelschall]
6495 *) Provide APACI --without-support option to be able to disable the build
6496 and installation of the support tools from the src/support/ area.
6497 Although its useful to have these installed per default we should provide
6498 a way to compile and install without them for backward-compatibility.
6499 [Ralf S. Engelschall]
6501 *) Add of the new APache eXtenSion (apxs) support tool for building and
6502 installing modules into an _already installed_ Apache package through the
6503 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6504 this approach actually doesn't need the Apache source tree. The
6505 (APACI-installed) server package is enough, because this now includes the
6506 Apache C header files (PREFIX/include) and the new APXS tool
6507 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6508 module authors to build their Apache modules _OUTSIDE_ the Apache source
6509 tree while avoiding them to fiddle around with the totally platform
6510 dependend way of compiling DSO files. The tool supports all ranges of
6511 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6512 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6513 on-the-fly generate a minimalistic Makefile and sample module for the
6514 first step to provide both a quick success event and to demonstrate the
6515 APXS mechanism to module authors. [Ralf S. Engelschall]
6517 *) Fix core dumps in use of CONNECT in proxy.
6518 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6520 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6521 so that users have examples of how CustomLog can be used.
6524 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6525 the Apache distribution tree. Until Apache 1.3 there was no real
6526 out-of-the-box batch-capable build and installation procedure for the
6527 complete Apache package. This is now provided by a top-level "configure"
6528 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6529 to provide a GNU Autoconf-style frontend which is capable to both drive
6530 the old src/Configure stuff in batch and additionally installs the
6531 package with a GNU-conforming directory layout. Any options from the old
6532 configuration scheme are available plus a lot of new options for flexibly
6533 customizing Apache. [Ralf S. Engelschall]
6535 *) The floating point ap_snprintf code wasn't threadsafe.
6536 Had to remove the HAVE_CVT macro in order to do threadsafe
6537 calling of the ?cvt() floating point routines. [Dean Gaudet]
6539 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6541 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
6542 [Jim Jagielski] PR#1901
6544 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6545 Configure knows which CC we are using. [Jim Jagielski]
6547 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6548 was defined in a parent directory. [Lars Eilebrecht]
6550 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6551 a generic printf-style routine that can call arbitrary output
6552 routines. Use this to replace http_bprintf.c. Add new routines
6553 psprintf(), pvsprintf() which allocate the exact amount of memory
6554 required for a string from a pool. Use psprintf() to clean up
6555 various bits of code which used ap_snprintf()/pstrdup().
6558 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6559 ap_snprintf() has different semantics and formatting codes than
6560 snprintf(). [Dean Gaudet]
6562 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6563 is necessary on at least Solaris where the /etc/rc?.d scripts
6564 are run with these signals ignored, and "SIG_IGN" settings are
6565 maintained across exec().
6566 [Rein Tollevik <reint@sys.sol.no>] PR#2009
6568 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
6569 used instead of lstat() and thus this flag didn't work as expected.
6570 [Rein Tollevik <reint@sys.sol.no>] PR#2010
6572 *) Fix the proxy pass-through feature of mod_rewrite for the case of
6573 existing QUERY_STRING now that mod_proxy was recently changed because of
6574 the new URL parsing stuff. [Ralf S. Engelschall]
6576 *) A few changes to scoreboard definitions which helps gcc generate
6577 better code. [Dean Gaudet]
6579 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
6580 be a signed bitfield. So mark a few bitfields as signed to
6581 ensure correct code. [Dean Gaudet]
6583 *) The default for HostnameLookups was changed to Off, but there
6584 was a problem and it wasn't taking effect. [Dean Gaudet]
6586 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
6589 *) After a SIGHUP the listening sockets in the parent weren't
6590 properly marked for closure on fork().
6591 [Jürgen Keil <jk@tools.de>] PR#2000
6593 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6594 therefore not exposed to %2F -> '/' translations and 2) the request
6595 is a proxy request, so we're not dealing with a local resource anyway.
6596 Without this, the proxy would fail to work for any URL's with
6597 %2f in them (occurs quite often in
6598 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6600 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6602 *) Make the shared object compilation command more portable by avoiding
6603 the direct combination of `-c' & `-o' which is not honored by some
6604 compilers like UnixWare's cc. [Ralf S. Engelschall]
6606 *) WIN32: the proxy was creating filenames missing the last four
6607 characters. While this normally doesn't stop anything from
6608 working, it can result in extra collisions.
6609 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
6611 *) Now mod_proxy uses the response string (in addition to the response status
6612 code) from the already used FTP SIZE command to setup the Content-Length
6613 header if available. [Ralf S. Engelschall] PR#1183
6615 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6616 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6617 name was really too generic, added documentation for this directive to
6618 the mod_proxy.html and corrected the hyperlink to it in the
6619 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
6621 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6622 faster [Martin Kraemer]
6624 *) Make Configure die when you give it an unknown command switch.
6627 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6628 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6629 and per default compiled support programs have manual pages - just to
6630 document our stuff a little bit more and to be able to do really
6631 Unix-like installations ;-) [Ralf S. Engelschall]
6633 *) Major cleanups to the Configure script to make it and its generated
6634 Makefiles again readable and maintainable: add SRCDIR option, removed
6635 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6636 generated sections, consequently added Makefile headers with inheritance
6637 information, added subdir movement messages for easier following where
6638 the build process currently stays (more verbose then standard Make, less
6639 verbose than GNU make), same style to comments in the Configure script,
6640 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6642 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6643 from the ZeusBench benchmarking program and can be used to determine the
6644 response performance of an Apache installation. This version is
6645 officially licensed with Zeus Technology, Ltd. See the license agreement
6646 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
6647 [Ralf S. Engelschall]
6649 *) API: Various core functions that are definately not part of the API
6650 have been made static, and a few have been marked API_EXPORT. Still
6651 more have been marked CORE_EXPORT and are not intended for general
6652 use by modules. [Doug MacEachern, Dean Gaudet]
6654 *) mod_proxy was not clearing the Proxy-Connection header from
6655 requests; now it does. This did not violate any spec, however
6656 causes poor interactions when you are talking to remote proxies.
6657 [Marc Slemko] PR#1741
6659 *) Various cleanups to the command line interface and manual pages.
6660 [Ralf S. Engelschall]
6662 *) cfg_getline() was not properly handling lines that did not end
6663 with a line termination character. [Marc Slemko] PR#1869, 1909
6665 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6667 *) Clean up some undocumented behavior of mod_setenvif related to
6668 "merging" two SetEnvIf directives when they match the same header
6669 and regex. Document that mod_setenvif will perform comparisons in
6670 the order they appear in the config file. Optimize mod_setenvif by
6671 doing more work at config time rather than at runtime.
6674 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6675 to allow for modules to overrule them and to reduce redefinition
6676 warnings [Jim Jagielski]
6678 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6681 *) Making the hard-coded cross-module function call mime_find_ct() (from
6682 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6683 checking is really called even for proxy requests except for URLs with
6684 HTTP schemes (because there we can optimize by not running the type
6685 checking hooks due to the fact that the proxy gets the MIME Content-type
6686 from the remote host later). This change cleans up mod_mime by removing
6687 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6688 especially unbundles mod_proxy and mod_mime. This way they both now can
6689 be compiled as shared objects and are no longer tied together.
6690 [Ralf S. Engelschall]
6692 *) util.c cleanup and speedup. [Dean Gaudet]
6694 *) API: Clarification, pstrndup() will always copy n bytes of the source
6695 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6697 *) Mark module command_rec and handler_rec structures const so that they
6698 end up in the read-only data section (and are friendlier to systems
6699 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6701 *) Add check to the "Port" directive to make sure the specified
6702 port is in the appropriate range. [Ben Hyde]
6704 *) Performance improvements to invoke_handler().
6705 [Dmitry Khrustalev <dima@bog.msu.su>]
6707 *) Added support for building shared objects even for library-style modules
6708 (which are built from more than one object file). This now provides the
6709 ability to build mod_proxy as a shared object module. Additionally
6710 modules like mod_example are now also supported for shared object
6711 building because the generated Makefiles now no longer assume there is at
6712 least one statically linked module. [Ralf S. Engelschall]
6714 *) API: Clarify usage of content_type, handler, content_encoding,
6715 content_language and content_languages fields in request_rec. They
6716 must always be lowercased; and the strings pointed to shouldn't
6717 be modified (you must copy them to modify them). Fix a few bugs
6718 related to this. [Dean Gaudet]
6720 *) API: Clarification: except for RAW_ARGS, all command handlers can
6721 treat the char * parameters as permanent, and modifiable. There
6722 is no need to pstrdup() them. Clean up some needless pstrdup().
6725 *) Now mod_so keeps track of which module shared objects with which names
6726 are loaded and thus avoids multiple loading and unloading and irritating
6727 error_log messages. [Ralf S. Engelschall]
6729 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6730 environment variable in the apache core. But that tweaking interferes
6731 with mod_setenv. So don't tweak if the user has specified an explicit
6732 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6734 *) rputs() did not calculate r->sent_bodyct properly.
6735 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6737 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6738 name, or left unset if this value is unavailable. Apache was setting
6739 it to the IP address when unavailable.
6740 [Tony Finch <fanf@demon.net>] PR#1925
6742 *) Various improvements to the configuration and build support for compiling
6743 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6744 OSF1 support with GCC and vendor compilers was added. This way shared
6745 object support is now provided out-of-the-box for FreeBSD, Linux,
6746 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6747 [Ralf S. Engelschall]
6749 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6750 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6751 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6753 *) Fix one more special locking problem for RewriteMap programs in
6754 mod_rewrite: According to the documentation of flock(), "Locks are on
6755 files, not file descriptors. That is, file descriptors duplicated
6756 through dup(2) or fork(2) do not result in multiple instances of a lock,
6757 but rather multiple references to a single lock. If a process holding a
6758 lock on a file forks and the child explicitly unlocks the file, the
6759 parent will lose its lock.". To overcome this we have to make sure the
6760 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6761 the case by opening it in the child_init instead of the module_init API
6762 hook. [Ralf S. Engelschall] PR#1029
6764 *) Change to Location and LocationMatch semantics. LocationMatch no
6765 longer lets a single slash match multiple adjacent slashes in the
6766 URL. This change is for consistency with RewriteRule and
6767 AliasMatch. Multiple slashes have meaning in URLs that they do
6768 not have in (some) filesystems. Location on the other hand can
6769 be considered a shorthand for a more complicated regex, and it
6770 does match multiple slashes with a single slash -- which is
6771 also consistent with the Alias directive.
6772 [Dean Gaudet] related PR#1440
6774 *) Fix bug with mod_mime_magic causing certain files, including files
6775 of length 0, to result in no response from the server.
6778 *) The Configure script now generates src/include/ap_config.h which
6779 contains the set of defines used when Apache is compiled on a platform.
6780 This file can then be included by external modules before including
6781 any Apache header files in case they are being built separately from
6782 Apache. Along with this change, a couple of minor changes were
6783 made to make Apache's #defines coexist peacefully with any autoconf
6784 defines an external module might have. [Rasmus Lerdorf]
6786 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6787 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6788 chance by the API to initialize its per-server configuration and thus
6789 receives the wrong one from the main server. This is now avoided by
6790 remembering the server together with the config structure while
6791 configuring and later assuming there is no config when we see a
6792 difference between the remembered server and the one calling us.
6793 [Ralf S. Engelschall] PR#1790
6795 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6796 is automatically disabled under configure time when the dbm_xxx functions
6797 are not available. Second, two heavy source code errors in the DBM
6798 support code were fixed. This makes DBM RewriteMap's usable again after
6799 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6801 *) Now all configuration files support Unix-style line-continuation via
6802 the trailing backslash ("\") character. This enables us to write down
6803 complex or just very long directives in a more readable way. The
6804 backslash character has to be really the last character before the
6805 newline and it has not been prefixed by another (escaping) backslash.

6811 *) To deal with modules being compiled and [dynamically] linked
6812 at a different time from the core, the SERVER_VERSION and
6813 SERVER_BUILT symbols have been abstracted through the new
6814 API routines apapi_get_server_version() and apapi_get_server_built().
6817 *) WIN32: Preserve trailing slash in canonical path (and hence
6818 in PATH_INFO). [Paul Sutton, Ben Laurie]
6820 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6821 depending on the rev of Solaris and what mixture of modules
6822 are in use. So it has been disabled, and Solaris is back to
6823 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6824 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6825 up static content only servers. Or it may fail unpredictably.

6828 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6831 *) API: Rewrite of absoluteURI handling, and in particular how
6832 absoluteURIs match vhosts. Unless a request is a proxy request, a
6833 "http://host" url is treated as if a similar "Host:" header had been
6834 supplied. This change was made to support future HTTP/1.x protocols
6835 which may require clients to send absoluteURIs for all requests.
6837 In order to achieve this change subtle changes were made to the API. In a
6838 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6839 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6840 by the core, modules must set it during the post_read_request or
6841 translate_names phase.
6843 Plus changes to the virtualhost test suite for absoluteURI testing.
6845 This fixes several bugs with the proxy proxying requests to vhosts
6846 managed by the same httpd.
6849 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6850 code from mod_rewrite. The vhost matching is now performed by a
6851 globally available function matches_request_vhost(). [Dean Gaudet]

6867 *) API: A new source module main/util_uri.c; It contains a routine
6868 parse_uri_components() and friends which breaks a URI into its component
6869 parts. These parts are stored in a uri_components structure called
6870 parsed_uri within each request_rec, and are available to all modules.
6871 Additionally, an unparse routine is supplied which re-assembles the URI
6872 components back to an URI, optionally hiding the username:password@ part
6873 from ftp proxy requests, and other useful routines. Within the structure,
6874 you find on a ready-for-use basis:
6875 scheme; /* scheme ("http"/"ftp"/...) */
6876 hostinfo; /* combined [user[:password]@]host[:port] */
6877 user; /* user name, as in http://user:passwd@host:port/ */
6878 password; /* password, as in http://user:passwd@host:port/ */
6879 hostname; /* hostname from URI (or from Host: header) */
6880 port_str; /* port string (integer representation is in "port") */
6881 path; /* the request path (or "/" if only scheme://host was given) */
6882 query; /* Everything after a '?' in the path, if present */
6883 fragment; /* Trailing "#fragment" string, if present */
6884 This is meant to serve as the platform for *BIG* savings in
6885 code complexity for the proxy module (and maybe the vhost logic).
6888 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6889 ${map:key}) available for all location where a string is created in
6890 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

6892 possible expansions are consequently usable at all string creation
6893 locations. [Ralf S. Engelschall]
6895 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6896 and not 1) and the per-virtual-server merging of directives. Now all
6897 directives except `RewriteEngine' and `RewriteOption' are either
6898 completely overridden (default) or completely inherited (when
6899 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6930 type but with a special post-processing for the looked-up value: It
6931 parses it into alternatives according to `|' chars and then only one
6932 particular alternative is chosen randomly (this is an essential
6933 functionality needed for balancing between backend-servers when using
6934 Apache as a Reverse Proxy. The looked up value here is a list of
6935 servers). Second, `int' with the built-in maps named `tolower' and
6936 `toupper' which can be used to map URL parts to a fixed case (this is an
6937 essential feature to fix the case of server names when doing mass
6938 virtual-hosting with the help of mod_rewrite instead of using
6939 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6940 Jay Soffian <jay@cimedia.com>] PR#1631
6942 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6943 This directive lets Apache adjust the URL in Location-headers on HTTP
6944 redirect responses sent by the remote server. This way the virtually
6945 mapped area is no longer left on redirects and thus by-passed which is
6946 especially essential when running Apache as a reverse proxy.

6949 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
6950 hidden. [Alvaro Martinez Echevarria]
6952 *) Apache will, when started with the -X (single process) debugging flag,
6953 honor the SIGINT or SIGQUIT signals again now. This capability got lost
6954 a while ago during OS/2 signal handling changes.
6956 *) [PORT] Work around the fact that NeXT runs on more than the
6957 m68k chips in mod_status [Scott Anguish and Timothy Luoma
6960 *) [PORT] Recognize FreeBSD versions so we can use the OS regex as well
6961 as handling unsigned-chars for FreeBSD v3 and v2 [Andrey Chernov
6962 <ache@nagual.pp.ru> and Jim] PR#1450
6964 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
6965 In particular the handlers could trigger themselves into an infinite
6966 loop if RLimitMem was used with a small amount of memory -- too small
6967 for the signal stack frame to be set up. [Dean Gaudet]

6978 *) API: As Ken suggested the check_cmd_context() function and related
6979 defines are non-static now so modules can use 'em. [Martin Kraemer]
6981 *) mod_info would occasionally produce an unpaired <tt> in its
6982 output. Fixed. [Martin Kraemer]
6984 *) By default AIX binds a process (and it's children) to a single
6985 processor. httpd children now unbind themselves from that cpu
6986 and re-bind to one selected at random via bindprocessor()
6989 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
6990 effect. Work around it by using RLIMIT_AS for the RLimitMEM
6991 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
6993 *) mod_mime_magic error message should indicate the filename when
6994 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
6996 *) Previously Apache would permit </Files> to end <FilesMatch> (and
6997 similary for Location and Directory), now this is diagnosed as an
6998 error. Improve error messages for mismatched sections (<Files>,
6999 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
7000 [Dean Gaudet, Martin Kraemer]
7002 *) <Files> is not permitted within <Location> (because of the
7003 semantic ordering). [Dean Gaudet] PR#379
7005 *) <Files> with wildcards was broken by the change in wildcard
7006 semantics (* does not match /). To fix this, <Files> now
7007 apply only to the basename of the request filename. This
7008 fixes some other inconsistencies in <Files> semantics

7016 *) Various errors from select() and accept() in child_main() would
7017 result in an infinite loop. It seems these two tickle kernel
7018 or library bugs occasionally, and result in log spammage and
7019 a generally bad scene. Now the child exits immediately,
7020 which seems to be a good workaround.

7034 Changes with Apache 1.3b5
7036 *) Source file dependencies in Makefile.tmpl files throughout the

7040 *) Preserve the content encoding given by the AddEncoding directive
7041 when the client doesn't otherwise specify an encoding.
7042 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>]
7044 *) Sort out problems with canonical filename handling happening too late.
7045 [Dean Gaudet, Ben Laurie]
7047 Changes with Apache 1.3b4
7049 *) The module structure was modified to include a *dynamic_load_handle
7050 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
7051 has been bumped accordingly. [Paul Sutton]
7053 *) All BrowserMatch directives mentioned in
7054 htdocs/manual/known_client_problems.html are in the default
7055 configuration files. [Lars Eilebrecht]
7057 *) MiNT port update. [Jan Paul Schmidt]
7059 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
7060 equivalent, similarly for x-compress and compress. Apache
7061 now ignores a leading x- when comparing encodings. It also
7062 preserves the encoding the client requests (for example if
7063 it requests x-gzip, then Apache will respond with x-gzip
7064 in the Content-Encoding header).
7065 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
7067 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
7069 *) Added mod_so module to support dynamic loading of modules on Unix
7070 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
7071 instead of AddModule in Configuration to build shared modules
7072 [Sameer Parekh, Paul Sutton]
7074 *) Minor cleanups to r->finfo handling in some modules.
7077 *) Abstract read()/write() to ap_read()/ap_write().
7078 Makes it easier to add other types of IO code such as SFIO.
7081 *) API: Generalize default_port manipulations to make support of
7082 different protocols easier. [Ben Laurie, Randy Terbush]
7084 *) There are many cases where users do not want Apache to form
7085 self-referential urls using the "canonical" ServerName and Port.
7086 The new UseCanonicalName directive (default on), if set to off
7087 will cause Apache to use the client-supplied hostname and port.
7088 API: Part of this change required a change to the construct_url()
7089 prototype; and the addition of get_server_name() and
7091 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
7092 PR#315, 459, 485, 1433
7094 *) Yet another rearrangement of the source tree.. now all the common
7095 header files are in the src/include directory. The -Imain -Iap
7096 references in Makefiles have been changed to the simpler -Iinclude
7097 instead. In addition to simplifying the build a little bit, this
7098 also makes it clear when a module is referencing something in a
7099 other than kosher manner (e.g., the proxy including mod_mime.h).
7100 Module-private header files (the proxy, mod_mime, the regex library,
7101 and mod_rewrite) have not been moved to src/include; nor have
7102 the OS-abstraction files. [Ken Coar]
7104 *) Fix a bug where r->hostname didn't have the :port stripped
7105 from it. [Dean Gaudet]
7107 *) Tweaked the headers_out table size, and the subprocess_env
7108 table size guess in rename_original_environment(). Added
7109 MAKE_TABLE_PROFILE which can help discover make_table()
7110 calls that use too small an initial guess, see alloc.c.
7113 *) Options and AllowOverride weren't properly merging in the main
7114 server setting inside vhosts (only an issue when you have no
7115 <Directory> or other section containing an Options that affects
7116 a request). Options +foo or -foo in the main_server wouldn't
7117 affect the main_server's lookup defaults. [Dean Gaudet]
7119 *) Variable 'cwd' was being used pointlessly before being set.
7122 *) r->allowed handling cleaned up in the standard modules.
7125 *) Some case-sensitivity issues cleaned up to be consistent with
7126 RFC2068. [Dean Gaudet]
7128 *) SIGURG doesn't exist everywhere.
7129 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7131 *) mod_unique_id was erroneously generating a second unique id when
7132 an internal redirect occured. Such redirects occur, for example,
7133 when processing a DirectoryIndex match. [Dean Gaudet]
7135 *) API: table_add, table_merge, and table_set include implicit pstrdup()
7136 of the key and value. But in many cases this is not required
7137 because the key/value is a constant, or the value has been built
7138 by pstrcat() or other similar means. New routines table_addn,
7139 table_mergen, and table_setn have been added to the API, these
7140 routines do not pstrdup() their arguments. The core code and
7141 standard modules were changed to take advantage of these routines.
7142 The resulting server is up to 20% faster in some situations.
7144 Note that it is easy to get code subtly wrong if you pass a key/value
7145 which is in a pool other than the pool of the table. The only
7146 safe thing to do is to pass key/values which are in the pool of
7147 the table, or in one of the ancestors of the pool of the table.
7148 i.e. if the table is part of a subrequest, a value from the main
7149 request's pool is OK since the subrequest pool is a sub_pool of the
7150 main request's pool (and therefore has a lifespan at most as long as
7151 the main pool). There is debugging code which can detect improper
7152 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
7153 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
7155 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
7156 which don't exist on disk more gracefully; handles vhosts properly.
7157 Update documentation to reflect the code -- if there's no
7158 MimeMagicFile directive then the module is not enabled.
7161 *) PORT: Some older *nix dialects cannot automatically start scripts
7162 which begin with a #! interpreter line (the shell starts the scripts
7163 appropriately on these platforms). Apache now supports starting of
7164 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
7165 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
7168 *) API: "typedef array_header table" removed from alloc.h, folks should
7169 have been writing to use table as if it were an opaque type, but even
7170 some standard modules got this wrong. By changing the definition
7171 to "typedef struct table table" module authors will receive compile
7172 time warnings that they're doing the wrong thing. This change
7173 facilitates future changes with more sophisticated table
7174 structures. Specifically, module authors should be using table_elts()
7175 to get access to an array_header * for the table. [Dean Gaudet]
7177 *) API: Renamed new_connection() to avoid namespace collision with LDAP
7178 library routines. [Ken Coar, Rasmus Lerdorf]
7180 *) WIN32: mod_speling is now available on the Win32 platform.
7183 *) For clarity the following compile time definition was changed:
7185 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
7187 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
7188 and not be a general notice that the OS has mmap(). Now the
7189 HAVE_MMAP/SHMGET #defines strictly are informational that the
7190 OS has that method of shared memory; the type to use for
7191 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
7192 and USE_SHMGET_SCOREBOARD). This allows outside modules to
7193 determine if shared memory is available and allows Apache
7194 to determine the best method to use for the scoreboard.
7197 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
7198 as do various earlier versions. It should be safe on all versions.
7199 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
7200 the slack code. A few other cleanups for Unixware.

7203 *) PORT: A/UX can handle single-listen accepts without mutex
7204 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
7206 *) When die() happens we need to eat any request body if one exists.
7207 Otherwise we can't continue with a keepalive session. This shows up
7208 as a POST problem with MSIE 4.0, typically against pages which are
7209 authenticated. [Roy Fielding] PR#1399
7211 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
7212 header will be passed to CGIs. This is generally a security hole, so
7213 it's not a default. [Marc Slemko] PR#549
7215 *) Fix Y2K problem with date printing in suexec log.

7218 *) WIN32 deserves a pid file. [Ben Hyde]
7220 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
7222 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
7223 The choice of flock vs. fcntl was made based on timings which showed that
7224 even on non-NFS, non-exported filesystems fcntl() was an order of
7225 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7226 that single socket users will see no difference. [Dean Gaudet] PR#467
7228 *) "File does not exist" error message was erroneously including the
7229 errno. [Marc Slemko]
7231 *) Improve the warning message generated when a client drops the
7232 connection (hits stop button, etc.) during a send. [Roy Fielding]
7234 *) Defining GPROF will disable profiling in the parent and enable it
7235 in the children. If you're profiling under Linux this is pretty much
7236 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
7238 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
7241 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
7242 gcc functionality. Work around it.

7245 *) Some linkers complain when .o files contain no functions.
7246 [Keith Severson <keith@sssd.navy.mil>] PR#1614
7248 *) Some const declarations in mod_imap.c that were added for debugging
7249 purposes caused some compilers heartburn without adding any
7250 significant value, so they've been removed. [Ken Coar]
7252 *) The src/main/*.h header files have had #ifndef wrappers added to
7253 insulate them against duplicate calls if they get included through
7254 multiple paths (e.g., in .c files as well as other .h files).
7257 *) The libap routines now have a header file for their prototypes,
7258 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
7260 *) mod_autoindex with a plaintext header file would emit the <PRE>
7261 start-tag before the HTML preamble, rather than after the preamble
7262 but before the header file contents. [John Van Essen <jve@gamers.org>]
7265 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7266 only an issue on systems without a MAXDNAME define or where
7267 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7269 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7270 is used to read various types of files such as htaccess and
7271 htpasswd files. [Marc Slemko]
7273 *) SECURITY: Ensure that the buffer returned by ht_time is always
7274 properly null terminated. [Marc Slemko]
7276 *) The "Connection" header could be sent back with multiple "close"
7277 tokens. Not an error, but a waste.
7278 [Ronald.Tschalaer@psi.ch] PR#1683
7280 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
7281 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
7283 *) "basic" auth needs a case-insensitive comparison.
7284 [Ronald.Tschalaer@psi.ch] PR#1666
7286 *) For maximum portability, the environment passed to CGIs should
7287 only contain variables whose names match the regex
7288 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
7289 underscores over any character outside the regex. This
7290 affects HTTP_* variables, in a way that should be backward
7291 compatible for all the standard headers; and affects variables
7292 set with SetEnv/BrowserMatch and similar directives.
7295 *) mod_speling returned incorrect HREF's when an ambigous match
7296 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
7297 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
7299 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
7300 (the Siemens BS2000/OSD family) in the POSIX subsystem
7303 *) PORT: Fix problem killing children when terminating. Allow ^C
7304 to shut down the server. [Brian Havard]
7306 *) pstrdup() is implicit in calls to table_* functions, so there's
7307 no need to do it before calling. Clean up a few cases.
7308 [Marc Slemko, Dean Gaudet]
7310 *) new -C and -c command line arguments

7328 possible buffer overflows and a possible infinite loop.
7329 [Dean Gaudet, Marc Slemko]
7331 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7332 including fixing a possible buffer overflow. [Dean Gaudet]
7334 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
7335 (connections are not dropped). Code can handle graceful restarts
7336 (but there is as yet no way to signal this to Apache). Various
7337 other cleanups. [Paul Sutton]
7339 *) The aplog_error changes specific to 1.3 introduced a buffer
7340 overrun in the (now legacy) log_printf function. Fixed.
7343 *) mod_digest didn't properly deal with proxy authentication. It
7344 also lacked a case-insensitive comparision of the "Digest"
7345 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
7347 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]

7356 ap_cpystrn() for performance and functionality reasons.

7373 *) Interim (slow) fix for p->sub_pool critical sections in
7374 alloc.c (affects win32 only). [Ben Hyde]
7376 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
7378 *) send_fd_length() did not calculate total_bytes_sent properly.
7379 [Ben Reser <breser@regnow.com>] PR#1366
7381 *) The bputc() macro was not properly integrated with the chunking
7382 code; in many cases modules using bputc() could cause completely
7383 bogus chunked output. (Typically this will show up as problems
7384 with Internet Explorer 4.0 reading a page, but other browsers
7385 having no problem.) [Dean Gaudet]
7387 *) Create LARGE_WRITE_THRESHOLD define which determines how many
7388 bytes have to be supplied to bwrite() before it will consider
7389 doing a writev() to assemble multiple buffers in one system
7390 call. This is critical for modules such as mod_include,
7391 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
7392 strings in some cases. The result would be extra effort
7393 setting up writev(), and in many cases extra effort building
7394 chunks. The default is 31, it can be overriden at compile
7397 *) Move the gid switching code into the child so that log files

7410 the libap consolidation work. [Ken Coar]

7468 *) WIN32: Allocate the correct amount of memory for the scoreboard.
7471 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]

7477 error messages. [Ben Hyde]
7479 Changes with Apache 1.3b3
7481 *) WIN32: Work around brain-damaged spawn calls that can't deal
7482 with spaces and slashes. [Ben Laurie]
7484 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
7485 The problem was that certain undocumented environment variables
7486 needed for sockets to work under Win32 were not being passed.
7487 [Frank Faubert <frank@sane.com>]
7489 *) Add a "-V" command line flag to the httpd binary. This
7490 flag shows some of the defines that Apache was compiled with.
7491 It is useful for debugging purposes. [Martin Kraemer]
7493 *) Start separating the ap_*() routines into their own library, so they
7494 can be used by items in src/support among other things.
7495 [Ken Coar] PR#512, 905, 1252, 1308
7497 *) Give a more informative error when no AuthType is set.
7500 *) Remove strtoul() use from mod_proxy because it isn't available
7501 on all platforms. [Marc Slemko] PR#1214
7503 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
7504 This turns out to be a bug in Winsock - select() doesn't always
7505 return the correct status. [Ben Laurie]
7507 *) Directives owned by http_core can now use the new check_cmd_context()
7508 routine to ensure that they're not being used within a container
7509 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
7511 *) PORT: Recent changes made it necessary to add explicit prototype
7512 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
7514 *) It was necessary to distinguish between resources which are
7515 allocated in the parent, for cleanup in the parent, and resources
7516 which are allocated in each child, for cleanup in each child.
7517 A new pool was created which is passed to the module child_init
7518 and child_exit functions; modules are free to register per-child
7519 cleanups there. This fixes a bug with reliable piped logs.
7522 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
7523 unless it was also doing FancyIndexes, but it displayed the
7524 HeaderName file at the top under all circumstances. It now shows
7525 the ReadmeName file for simple indices, too, as it should.
7528 *) http_core was mmap()ing even in cases where it wasn't going to
7529 read the file. [Ben Hyde <bhyde@gensym.com>]
7531 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
7532 Now the rewriting engine (the heart of mod_rewrite) is organized more
7533 straight-forward, first time well documented and reduced to the really
7534 essential parts. All redundant cases were stripped off and processing now
7535 is the same for both per-server and per-directory context with only a
7536 minimum difference (the prefix stripping in per-dir context). As a
7537 side-effect some subtle restrictions and two recently discovered problems
7538 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
7539 context and restrictions on the substitution URL on redirects.
7540 Additionally some minor source cleanups were done.

7682 server settings in <VirtualHost> blocks, flagging unhandled multiple
7683 arguments to <Directory>, <Files> etc.)

7690 *) New support tool: src/support/split-logfile, a sample Perl script which
7691 splits up a combined access log into separate files based on the
7692 name of the virtual host (listed first in the log records by "%v").
7695 Changes with Apache 1.3b2 (there is no 1.3b1)
7697 *) TestCompile was not passing $LIBS [Dean Gaudet]
7699 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7702 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7703 rudimentary memory debugger which can be used on live servers with
7704 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7705 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7706 and free() for each object. This is far more expensive and should
7707 only be used for testing with tools such as Electric Fence and
7708 Purify. See main/alloc.c for more details. [Dean Gaudet]
7710 *) Configure uses a sh trap and didn't set its exitcode properly.
7711 [Dean Gaudet] PR#1159
7713 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7714 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7715 From a given ip:port, regardless what the Host: header is, you can
7716 only reach the vhosts defined on that ip:port. The precedence of
7717 vhosts was reversed to match other precedences in the config --
7718 the earlier vhosts override the later vhosts. All vhost matching was
7719 moved into http_vhost.[ch]. [Dean Gaudet]
7721 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7722 be used for whatever reason is appropriate (i.e. format() warnings
7723 for printf style functions). Both are enabled only with
7724 gcc >= 2.7.x (so that we have fewer support issues with older
7725 versions). [Dean Gaudet]
7727 *) Fix support for Proxy Authentication (we were testing the response
7728 status too early). [Marc Slemko]
7730 *) CoreDumpDirectory directive directs where the core file is
7731 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7732 received. [Marc Slemko, Dean Gaudet]
7734 *) PORT: Support for Atari MINT.
7735 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7737 *) When booting, apache will now detach itself from stdin, stdout,
7738 and stderr. stderr will not be detached until after the config
7739 files have been read so you will be able to see initial error
7740 messages. After that all errors are logged in the error_log.
7741 This makes it more convenient to start apache via rsh, ssh,
7742 or crontabs. [Dean Gaudet] PR#523
7744 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7745 Also removed the auto-generated link to www.apache.org that was the
7746 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7748 *) send_fb would not detect aborted connections in some situations.
7751 *) mod_include would use uninitialized data when parsing certain
7752 expressions involving && and ||. [Brian Slesinsky] PR#1139
7754 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7756 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7758 *) mod_autoindex improperly counted &escapes; as more than one
7759 character in the description. It also improperly truncated
7760 descriptions that were exactly the maximum length.
7763 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7764 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7767 *) mod_include now uses symbolic names to check for request success
7768 and return HTTP errors, and correctly handles all types of
7769 redirections (previously it only did temporary redirect correctly).
7770 [Ken Coar, Roy Fielding]
7772 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7773 r->filename. Since those two are meant to be in sync with each other
7774 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7776 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7777 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7779 *) Inetd mode (which is buggy) uses timeouts without having setup the
7780 jmpbuffer. [Dean Gaudet] PR#1064
7782 *) Work around problem under Linux where a child will start looping
7783 reporting a select error over and over.
7784 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7786 *) Fixed error in proxy_util.c when looping through multiple host IP
7787 addresses. [Lars Eilebrecht] PR#974
7789 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7790 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7791 bytes before writing, but it will never split a log entry across a
7792 buffer boundary. [Dean Gaudet]
7794 *) API: the short_score record has been split into two pieces, one which
7795 the parent writes on, and one which the child writes on. As part of
7796 this change the get_scoreboard_info() function was removed, and
7797 scoreboard_image was exported. This change fixes a race condition
7798 in file based scoreboard systems, and speeds up changes involving the
7799 scoreboard in earlier 1.3 development. [Dean Gaudet]
7801 *) API: New register_other_child() API (see http_main.h) which allows
7802 modules to register children with the parent for maintenance. It
7803 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7805 *) API: New piped_log API (see http_log.h) which implements piped logs,
7806 and will use register_other_child to implement reliable piped logs
7807 when it is available. The reliable piped logs part can be disabled
7808 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7809 logs is only available on Unix. [Dean Gaudet]
7811 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7812 meets_conditions(). This allows conditional HTTP selection to be
7813 handled separately from the storing of the header fields, and provides
7814 the ability for CGIs to set their own ETags for conditional checking.
7815 [Ken Coar, Roy Fielding] PR#895
7817 *) Changes to mod_log_config to allow naming of format strings.
7818 Format nicknames are defined with "LogFormat fmt nickname", and can
7819 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7822 *) New module, "mod_speling", which can help find files even when
7823 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7825 *) API: New function child_terminate() triggers the child process to
7826 exit, while allowing the child finish what it needs to for the
7827 current request first.
7828 [Doug MacEachern, Alexei Kosut]
7830 *) Windows now defaults to using full status reports with mod_status.
7831 [Alexei Kosut] PR #1094
7833 *) *Really* disable all mod_rewrite operations if the engine is off.
7834 Some things (like RewriteMaps) were checked/performed even if they
7835 weren't supposed to be. [Ken Coar] PR #991
7837 *) Implement a new timer scheme which eliminates the need to call alarm() all
7838 the time. Instead a counter in the scoreboard for each child is used to
7839 show when the child has made forward progress. The parent samples this
7840 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7841 progress has been made in the timeout period. This reduces the static
7842 request best-case syscall count to 22 from 29. This scheme is only
7843 used by systems with memory-based scoreboards. [Dean Gaudet]
7845 *) The proxy now properly handles CONNECT requests which are sent
7846 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7848 *) A script called apachectl has been added to the support
7849 directory. This script allows you to do things such as
7850 "apachectl start" and "apachectl restart" from the command
7853 *) Modules and core routines are now put into libraries, which
7854 simplifies the link line tremendously (among other advantages).
7857 *) Some of the MD5 names defined in Apache have been renamed to have
7858 an `ap_' prefix to avoid conflicts with routines supplied by
7859 external libraries. [Ken Coar]
7861 *) Removal of mod_auth_msql.c from the distribution. There are many
7862 other options for databases today. Rather than offer one option,
7863 offer none at this time. mod_auth_msql and other SQL database
7864 authentication modules can be found at the Apache Module Registry.
7865 http://modules.apache.org/ It would be nice to offer a generic
7866 mod_auth_sql option in the near future.
7868 *) PORT: BeOS support added [Alexei Kosut]
7870 *) Configure no longer accepts the -make option, since it creates
7871 Makefile on the fly based on Makefile.tmpl and Configuration.
7873 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7874 of forcibly killing off all its processes and exiting without
7875 cleaning up. [Alexei Kosut]
7877 *) API: A new field in the request_rec, r->mtime, has been added to
7878 avoid gratuitous parsing of date strings. It is intended to hold
7879 the last-modified date of the resource (if applicable). An
7880 update_mtime() routine has also been added to advance it if
7881 appropriate. [Roy Fielding, Ken Coar]
7883 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7884 deny access to the directory with a HTTP_FORBIDDEN. The previous
7885 behavior was to ignore the htaccess file if it could not be read.
7886 This change may make some setups with unreadable htaccess files
7887 stop working. [Marc Slemko] PR#817
7889 *) Add aplog_error() providing a mechanism to define levels of
7890 verbosity to the server error logging. This addition also provides
7891 the ability to log errors using syslogd. Error logging is configurable
7892 on a per-server basis using the LogLevel directive. Conversion
7893 of log_*() in progress. [Randy Terbush]
7895 *) Further enhance aplog_error() to not log filename, line number, and
7896 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7898 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7899 converted to long ones. Backslashes are converted to forward
7900 slashes. Case is converted to lower. Parts of URLs that do not
7901 correspond to files are left completely alone. [Ben Laurie]
7903 *) PORT: 2 new OSs added to the list of ports:
7904 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7905 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7907 *) Add the server version (SERVER_VERSION macro) to the "server
7908 configured and running" entry in the error_log. Also build an
7909 object file at link-time that contains the current time
7910 (SERVER_BUILT global const char[]), and include that in the
7913 *) Set r->headers_out when sending responses from the proxy.
7914 This fixes things such as the logging of headers sent from
7915 the proxy. [Marc Slemko] PR#659
7917 *) support/httpd_monitor is no longer distributed because the
7918 scoreboard should not be file based if at all possible. Use
7919 mod_status to see current server snapshot.
7921 *) (set_file_slot): New function, allowing auth directives to be
7922 independent of the server root, so the server documents can be
7923 moved to a different directory or machine more easily.
7924 [David J. MacKenzie]
7926 *) If no TransferLog is given explicitly, decline
7927 to log. This supports coexistence with other logging modules,
7928 such as the custom one that UUNET uses. [David J. MacKenzie]
7930 *) Check for titles in server-parsed HTML files.
7931 Ignore leading newlines and returns in titles. The old behavior
7932 of replacing a newline after <title> with a space causes the
7933 title to be misaligned in the listing. [David J. MacKenzie]
7935 *) Change mod_cern_meta to be configurable on a per-directory basis.
7936 [David J. MacKenzie]
7938 *) Add 'Include' directive to allow inclusion of configuration
7939 files within configuration files. [Randy Terbush]
7941 *) Proxy errors on connect() are logged to the error_log (nothing
7942 new); now they include the IP address and port that failed
7943 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7945 *) Various architectures now define USE_MMAP_FILES which causes
7946 the server to use mmap() for static files. There are two
7947 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7948 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7949 number of bytes written in one cycle from a single mmap()d object,
7950 default 32768). [Dean Gaudet]
7952 *) API: Added post_read_request API phase which is run right after reading
7953 the request from a client, or right after an internal redirect. It is
7954 useful for modules setting environment variables that depend only on
7955 the headers/contents of the request. It does not run during subrequests
7956 because subrequests inherit pretty much everything from the main
7957 request. [Dean Gaudet]
7959 *) Added mod_unique_id which is used to generate a unique identifier for
7960 each hit, available in the environment variable UNIQUE_ID.
7963 *) init_modules is now called after the error logs have been opened. This
7964 allows modules to emit information messages into the error logs.
7967 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7968 information for case where proxy module is not available. [Marc Slemko]
7970 *) PORT: Apache has need for mutexes to serialize its children around
7971 accept. In prior versions either fcntl file locking or flock file
7972 locking were used. The method is chosen by the definition of
7973 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7974 and FLOCK for flock(). New options have been added:
7975 - SYSVSEM to use System V style semaphores
7976 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7977 - USLOCK to use IRIX uslock
7978 Based on timing various techniques, the following changes were made
7980 - Linux 2.x uses flock instead of fcntl
7981 - Solaris 2.x uses pthreads
7982 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7983 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7984 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7985 Martijn Koster <m.koster@pobox.com>]
7987 *) PORT: The semantics of accept/select make it very desirable to use
7988 mutexes to serialize accept when multiple Listens are in use. But
7989 in the case where only a single socket is open it is sometimes
7990 redundant to serialize accept(). Not all unixes do a good job with
7991 potentially dozens of children blocked on accept() on the same
7992 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7993 the server will avoid serialization when listening on only one socket,
7994 and use serialization when listening on multiple sockets.
7995 [Dean Gaudet] PR#467
7997 *) Configure changes: TestLib replaced by TestCompile, which has
7998 some additional capability (such as doing a sanity check of
7999 the compiler and flags selected); the version of Solaris is now
8000 available via the #define value of SOLARIS2; IRIX n32bit libs
8001 now supported and selectable by new Configuration Rule: IRIXN32;
8002 We no longer default to -O2 optimization. [Jim Jagielski]
8004 *) Updated Configure: Configuration now uses AddModule to specify
8005 module source or binary file location, relative to src directory.
8006 Modules can be dropped into modules/extra, or in their own
8007 directory, and modules can come with a Makefile or Configure can
8008 create one. Modules can add compiler or library information to
8009 generated Makefiles. [Paul Sutton]
8011 *) Source core re-organisation: distributed modules are now in
8012 modules/standard. All other source code is in main. OS-specific
8013 code is in os/{unix,emx,win32} directories. [Paul Sutton]
8015 *) mod_browser has been removed, since it's replaced by mod_setenvif.
8018 *) Fix another long-standing bug in sub_req_lookup_file where it would
8019 happily skip past access checks on subdirectories looked up with
8020 relative paths. (It's used by mod_dir, mod_negotiation,
8021 and mod_include.) [Dean Gaudet]
8023 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
8024 N is the number of <Directory> sections, and M is the number of
8025 components in the filename of an object.
8027 To achieve this optimization the following config changes were made:
8028 - Wildcards (* and ?, not the regex forms) in <Directory>s,
8029 <Files>s, and <Location>s now treat a slash as a special
8030 character. For example "/home/*/public_html" previously would
8031 match "/home/a/andrew/public_html", now it only matches things
8032 like "/home/bob/public_html". This mimics /bin/sh behaviour.
8033 - It's possible now to use [] wildcarding in <Directory>, <Files>
8035 - Regex <Directory>s are applied after all non-regex <Directory>s.
8039 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
8040 and corrupted paths. [Dean Gaudet]
8042 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
8043 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
8044 be accessed now via backreferences $1..$9 in RewriteConds test-against
8045 strings in addition to RewriteRules subst string. Second the grouped
8046 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
8047 via backreferences %1..%9 both in following RewriteCond test-against
8048 strings and RewriteRules subst string. This provides maximum flexibility
8049 through the use of backreferences.
8050 Additionally the rewriting engine was cleaned up by putting common
8051 code to the new expand_backrefs_inbuffer() function.
8052 [Ralf S. Engelschall]
8054 *) When merging the main server's <Directory> and <Location> sections into
8055 a vhost, put the main server's first and the vhost's second. Otherwise
8056 the vhost can't override the main server. [Dean Gaudet] PR#717
8058 *) The <Directory> code would merge and re-merge the same section after
8059 a match was found, possibly causing problems with some modules.
8062 *) ip-based vhosts are stored and queried using a hashing function, which
8063 has been shown to improve performance on servers with many ip-vhosts.
8064 Some other changes had to be made to accommodate this:
8065 - the * address for vhosts now behaves like _default_
8066 - the matching process now is:
8067 - match an ip-vhost directly via hash (possibly matches main
8069 - if that fails, just pretend it matched the main server
8070 - if so far only the main server has been matched, perform
8071 name-based lookups (ServerName, ServerAlias, ServerPath)
8072 *only on name-based vhosts*
8073 - if they fail, look for _default_ vhosts
8074 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
8076 *) dbmmanage overhaul:
8077 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
8078 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
8079 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
8080 - provide better seed for rand
8081 - prompt for password as per getpass(3) (turn off echo, read from
8083 - use "newstyle" crypt based on $Config{osname} ($^O)
8084 - will not add a user if already in database, use new `update' command
8086 - added `check' command to check a users' password
8087 - added `import' command to convert existing password text-files or
8088 dbm files exported with `view'
8089 - more descriptive usage, general cleanup, 'use strict' clean, etc.
8092 *) Added psocket() which is a pool form of socket(), various places within
8093 the proxy weren't properly blocking alarms while registering the cleanup
8094 for its sockets. bclose() now uses pclose() and pclosesocket(). There
8095 was a bug where the client socket was being close()d twice due a still
8096 registered cleanup. [Dean Gaudet]
8098 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
8101 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
8102 [Jason Venner <jason@idiom.com>] PR#667
8104 *) Enable ``=""'' for RewriteCond directives to match against
8105 the empty string. This is the preferred way instead of ``^$''.
8106 [Ralf S. Engelschall]
8108 *) Fixed an infinite loop in mod_imap for references above the server root
8109 [Dean Gaudet] PR#748
8111 *) mod_proxy now has a ReceiveBufferSize directive, similar to
8112 SendBufferSize, so that the TCP window can be set appropriately
8113 for LFNs. [Phillip A. Prindeville]
8115 *) mod_browser has been replaced by the more general mod_setenvif
8116 (courtesy of Paul Sutton). BrowserMatch* directives are still
8117 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
8118 UnSetEnvIfZero directives. [Ken Coar]
8120 *) "HostnameLookups double" forces double-reverse DNS to succeed in
8121 order for remote_host to be set (for logging, or for the env var
8122 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
8125 *) mod_access overhaul:
8126 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
8127 and cidr syntax (i.e. 10.1.0.0/16). PR#762
8128 - Critical path was sped up by pre-computing a few things at config time.
8129 - The undocumented syntax "allow user-agents" was removed,
8130 the replacement is "allow from env=foobar" combined with mod_browser.
8131 - When used with hostnames it now forces a double-reverse lookup
8132 no matter what the directory settings are. This double-reverse
8133 doesn't affect any of the other routines that use the remote
8134 hostname. In particular it's still passed to CGIs and the log
8135 without the double-reverse check. Related PR#860.
8138 *) When a large bwrite() occurs (larger than the internal buffer size),
8139 while there is already something in the buffer, apache will combine
8140 the large write and the buffer into a single writev(). (This is
8141 in anticipation of using mmap() for reading files.)
8144 *) In obscure cases where a partial socket write occurred while chunking,
8145 Apache would omit the chunk header/footer on the next block. Cleaned
8146 up other bugs/inconsistencies in error conditions in buff.c. Fixed
8147 a bug where a long pause in DNS lookups could cause the last packet
8148 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
8150 *) API: Added child_exit function to module structure. This is called
8151 once per "heavy-weight process" just before a server child exit()'s
8152 e.g. when max_requests_per_child is reached, etc.
8153 [Doug MacEachern, Dean Gaudet]
8155 *) mod_include cleanup showed that handle_else was being used to handle
8156 endif. It didn't cause problems, but it was cleaned up too.
8159 *) mod_cern_meta would attempt to find meta files for the directory itself
8160 in some cases, but not in others. It now avoids it in all cases.
8163 *) mod_mime_magic would core dump if there was a decompression error.
8164 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
8166 *) PORT: some variants of DGUX require -lsocket -lnsl
8167 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
8169 *) mod_autoindex now allows sorting of FancyIndexed directory listings
8170 by the various fields (name, size, et cetera), either in ascending
8171 or descending order. Just click on the column header. [Ken Coar]
8173 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
8174 CPUs like the Alpha. Apache still stores ints in pointers, but that's
8175 the relatively safe direction. [Dean Gaudet] PR#344
8177 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
8178 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
8180 *) child_main avoids an unneeded call to select() when there is only one
8181 listening socket. [Dean Gaudet]
8183 *) In the event that the server is starved for idle servers it will
8184 spawn 1, then 2, then 4, ..., then 32 servers each second,
8185 doubling each second. It'll also give a warning in the errorlog
8186 since the most common reason for this is a poor StartServers
8187 setting. The define MAX_SPAWN_RATE can be used to raise/lower
8188 the maximum. [Dean Gaudet]
8190 *) Apache now provides an effectively unbuffered connection for
8191 CGI scripts. This means that data will be sent to the client
8192 as soon as the CGI pauses or stops output; previously, Apache would
8193 buffer the output up to a fixed buffer size before sending, which
8194 could result in the user viewing an empty page until the CGI finished
8195 or output a complete buffer. It is no longer necessary to use an
8196 "nph-" CGI to get unbuffered output. Given that most CGIs are written
8197 in a language that by default does buffering (e.g. perl) this
8198 shouldn't have a detrimental effect on performance.
8200 "nph-" CGIs, which formerly provided a direct socket to the client
8201 without any server post-processing, were not fully compatible with
8202 HTTP/1.1 or SSL support. As such they would have had to implement
8203 the transport details, such as encryption or chunking, in order
8204 to work properly in certain situations. Now, the only difference
8205 between nph and non-nph scripts is "non-parsed headers".
8206 [Dean Gaudet, Sameer Parekh, Roy Fielding]
8208 *) If a BUFF is switched from buffered to unbuffered reading the first
8209 bread() will return whatever remained in the buffer prior to the
8210 switch. [Dean Gaudet]
8212 Changes with Apache 1.3a1
8214 *) Added another Configure helper script: TestLib. It determines
8215 if a specified library exists. [Jim Jagielski]
8217 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8218 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8221 *) PORT: Some architectures use size_t for various lengths in network
8222 functions such as accept(), and getsockname(). The definition
8223 NET_SIZE_T is used to control this. [Dean Gaudet]
8225 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8226 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8227 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8229 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8230 [Igor N Kovalenko <infoh@mail.wplus.net>]
8232 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8233 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8234 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8235 [Dean Gaudet] related PR#875
8237 *) API: Correct child_init() slot declaration from int to void, to
8238 match the init() declaration. Update mod_example to use the new
8241 *) added transport handle slot (t_handle) to the BUFF structure
8244 *) get_client_block() returns wrong length if policy is
8245 REQUEST_CHUNKED_DECHUNK.

8253 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
8255 *) AddModuleInfo directive for mod_info which allows you to annotate
8256 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8258 *) Added NoProxy directive to avoid using ProxyRemote for selected
8259 addresses. Added ProxyDomain directive to cause unqualified
8260 names to be qualified by redirection.
8261 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8263 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8264 header to the remote host in the proxy. [Sameer Parekh and
8267 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8268 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8269 URLs, fixed rewritelog(), fixed forced response code handling on
8270 redirects from within .htaccess files, disabled pipe locking under
8271 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8272 no substitution, bugfixed situations where HostnameLookups is off, made
8273 mod_rewrite more thread-safe for NT port and fixed problem when creating
8274 an empty query string via "xxx?".
8275 This update also removes the copyright of Ralf S. Engelschall,
8276 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8277 exclusively copyrighted by the Apache Group now. This happened because
8278 the author now has gifted mod_rewrite exclusively to the Apache Group and
8279 no longer maintains an external version.
8280 [Ralf S. Engelschall]
8282 *) API: Added child_init function to module structure. This is called
8283 once per "heavy-weight process" before any requests are handled.
8284 See http_config.h for more details. [Dean Gaudet]
8286 *) Anonymous_LogEmail was logging on each subrequest.
8287 [Dean Gaudet] PR#421, 868
8289 *) API: Added is_initial_req() which tests if the request being
8290 processed is the initial request, or a subrequest.
8293 *) Extended SSI (mod_include) now handles additional relops for
8294 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8296 *) Configure fixed to correctly propagate user-selected options and
8297 settings (such as CC and OPTIM) to Makefiles other than
8298 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8300 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8301 directory indices to start with the contents of the HeaderName file
8302 if there is one. If there isn't one, the behaviour is unchanged.
8303 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8305 *) WIN32: Modules can now be dynamically loaded DLLs using the
8306 LoadModule/LoadFile directives. Note that module DLLs must be
8307 compiled with the multithreaded DLL version of the runtime library.
8308 [Alexei Kosut and Ben Laurie]
8310 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8311 This allows the admin to completely remove automatic indexing
8312 from the server, while still supporting the basic functions of
8313 trailing-slash redirects and DirectoryIndex files. Note that if
8314 you're carrying over an old Configuration file and you use directory
8315 indexing then you'll want to add:
8317 Module autoindex_module mod_autoindex.o
8319 before mod_dir in your Configuration. [Dean Gaudet]
8321 *) popendir/pclosedir created to properly protect directory scanning.
8322 [Dean Gaudet] PR#525
8324 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8325 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8326 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8329 *) The AccessFileName directive can now take more than one filename.
8330 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8332 *) The new mod_mime_magic can be used to "magically" determine the type
8333 of a file if the extension is unknown. Based on the unix file(1)
8334 command. [Ian Kluft <ikluft@cisco.com>]
8336 *) We now determine and display the time spent processing a
8337 request if desired. [Jim Jagielski]
8339 *) mod_status: PID field of "dead" child slots no longer displays
8340 main httpd process's PID. [Jim Jagielski]
8342 *) Makefile.nt added - to build all the bits from the command line:
8343 nmake -f Makefile.nt
8344 Doesn't yet work properly. [Ben Laurie]
8346 *) Default text of 404 error is now "Not Found" rather than the
8347 potentially misleading "File Not Found". [Ken Coar]
8349 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8350 for the net if we require people that actually need this data to
8351 enable it. [Linus Torvalds]
8353 *) directory_walk() is an expensive function, keep a little more state to
8354 avoid needless string counting. Add two new functions make_dirstr_parent
8355 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8356 The new functions are a little less general than make_dirstr, but
8357 work more efficiently (less memory, less string counting).
8360 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8361 to LDFLAGS) to avoid complications with lex rules in make files.
8362 [Dean Gaudet] PR#372
8364 *) run_method optimized to avoid needless scanning over NULLs in the
8365 module list. [Dean Gaudet]
8367 *) Revamp of (unix) scoreboard management code such that it avoids
8368 unnecessary traversals of the scoreboard on each hit. This is
8369 particularly important for high volume sites with a large
8370 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8371 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8372 httpd.h. [Dean Gaudet]
8374 *) In configurations using multiple Listen statements it was possible for
8375 busy sockets to starve other sockets of service. [Dean Gaudet]
8377 *) Added hook so standalone_main can be replaced at compile time
8378 (define STANDALONE_MAIN)
8381 *) Lowest-level read/write functions in buff.c will be replaced with
8382 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8383 compile time. The default sfio discipline will behave as apache
8384 would without sfio compiled in.
8387 *) Enhance UserDir directive (mod_userdir) to accept a list of
8388 usernames for the 'disable' keyword, and add 'enable user...' to
8389 selectively *en*able userdirs if they're globally disabled.
8392 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8393 will work with Netscape dbm files. (dbmmanage will probably not
8394 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8396 *) Add a ListenBacklog directive to control the backlog parameter
8397 passed to listen(). Also change the default to 511 from 512.
8400 *) API: A new handler response DONE which informs apache that the
8401 request has been handled and it can finish off quickly, similar to
8402 how it handles errors. [Rob Hartill]
8404 *) Turn off chunked encoding after sending terminating chunk/footer
8405 so that we can't do it twice by accident. [Roy Fielding]
8407 *) mod_expire also issues Cache-Control: max-age headers.
8410 *) API: Added kill_only_once option for free_proc_chain so that it won't
8411 aggressively try to kill off specific children. For fastcgi.
8412 [Stanley Gambarin <gambarin@OpenMarket.com>]
8414 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8416 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8417 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8418 attributes in the FancyIndexing IMG tags. [Ken Coar]
8420 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8422 *) PORT: Added Windows NT support
8423 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8425 Changes with Apache 1.2.6

8435 *) Support virtual hosts with wildcard port and/or multiple ports
8436 properly. [Ed Korthof <ed@organic.com>]
8438 *) Fixed some case-sensitivity issues according to RFC2068.
8441 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,

8447 *) SIGURG doesn't exist on all platforms.
8448 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8450 *) When an error occurs during a POST, or other operation with a

8454 *) When an error occurs in fcntl() locking suggest the user look up
8455 the docs for LockFile. [Dean Gaudet]
8457 *) table_set() and table_unset() did not deal correctly with

8464 *) r->connection->user was allocated in the wrong pool causing corruption
8465 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8467 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8468 Also removed the auto-generated link to www.apache.org that was the
8469 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8471 *) Multiple "close" tokens may have been set in the "Connection"
8472 header, not an error, but a waste.
8473 [Ronald.Tschalaer@psi.ch] PR#1683
8475 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8476 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8478 *) It appears the "257th byte" bug (see
8479 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8480 at the 256th byte as well. Fixed. [Dean Gaudet]
8482 *) mod_rewrite would not handle %3f properly in some situations.
8485 *) Apache could generate improperly chunked HTTP/1.1 responses when
8486 the bputc() or rputc() functions were used by modules (such as
8487 mod_include). [Dean Gaudet]
8489 *) #ifdef wrap a few #defines in httpd.h to make life easier on

8517 *) SECURITY: Ensure that the buffer returned by ht_time is always
8518 properly null terminated. [Marc Slemko]
8520 *) SECURITY: General mod_include cleanup, including fixing several
8521 possible buffer overflows and a possible infinite loop. This cleanup
8522 was done against 1.3 code and then backported to 1.2, the result
8523 is a large difference (due to indentation cleanup in 1.3 code).
8524 Users interested in seeing a smaller set of relevant differences
8525 should consider comparing against src/modules/standard/mod_include.c
8526 from the 1.3b3 release. Non-indentation changes to mod_include
8527 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8529 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8530 including fixing a possible buffer overflow. This cleanup also
8531 was done with 1.3 code as a basis, see the the previous note
8532 about mod_include. [Dean Gaudet]
8534 *) SECURITY: If a htaccess file can not be read due to bad
8535 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8536 The previous behavior was to ignore the htaccess file if it could not
8537 be read. This change may make some setups with unreadable
8538 htaccess files stop working. PR#817 [Marc Slemko]
8540 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8541 Make it O(n). This inefficiency could be used to mount a denial
8542 of service attack against the Apache server. Thanks to

8575 on this platform. [Marc Slemko]
8577 Changes with Apache 1.2.3
8579 *) The request to a remote proxy was mangled if it was generated as the
8580 result of a ProxyPass directive. URL schemes other than http:// were not
8581 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

8588 do for errors and cached responses. [Roy Fielding]
8590 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8592 Changes with Apache 1.2.2 [not released]
8594 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8595 happily skip past access checks on subdirectories looked up with relative
8596 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8599 *) Add lockfile name to error message printed out when
8600 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8603 *) Enhanced the chunking and error handling inside the buffer functions.
8604 [Dean Gaudet, Roy Fielding]
8606 *) When merging the main server's <Directory> and <Location> sections into
8607 a vhost, put the main server's first and the vhost's second. Otherwise
8608 the vhost can't override the main server. [Dean Gaudet] PR#717
8610 *) The <Directory> code would merge and re-merge the same section after
8611 a match was found, possibly causing problems with some modules.
8614 *) Fixed an infinite loop in mod_imap for references above the server root.
8615 [Dean Gaudet] PR#748
8617 *) mod_include cleanup showed that handle_else was being used to handle
8618 endif. It didn't cause problems, but it was cleaned up too.
8621 *) Last official synchronization of mod_rewrite with author version (because
8622 mod_rewrite is now directly developed by the author at the Apache Group):
8623 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8624 minus WIN32/NT stuff, but plus copyright removement.

8643 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8644 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8645 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

8666 [Dean Gaudet] PR#832
8668 *) API: In HTTP/1.1, whether or not a request message contains a body
8669 is independent of the request method and based solely on the presence
8670 of a Content-Length or Transfer-Encoding. Therefore, our default
8671 handlers need to be prepared to read a body even if they don't know
8672 what to do with it; otherwise, the body would be mistaken for the
8673 next request on a persistent connection. discard_request_body()
8674 has been added to take care of that. [Roy Fielding] PR#378

8677 release version number, such that it always increases along the
8678 same lines as our source code branching. [Roy Fielding]

8682 Changes with Apache 1.2.1
8684 *) SECURITY: Don't serve file system objects unless they are plain files,

8690 could contain "../" allowing a local user to "publish" any file on
8691 the system. No slashes are allowed now. [Dean Gaudet]
8693 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8694 (headers, readmes, titles), mod_negotiation (type maps), or
8695 mod_cern_meta (meta files). [Dean Gaudet]
8697 *) SECURITY: Apache will refuse to run as "User root" unless
8698 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8700 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8701 if it contained a .htaccess disallowing symlinks. This is contrary
8702 to the rule that symlink permissions are tested with the symlink
8703 options of the parent directory. [Dean Gaudet] PR#353
8705 *) CONFIG: The LockFile directive can be used to place the serializing
8706 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8707 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8710 *) Request processing now retains state of whether or not the request
8711 body has been read, so that internal redirects and subrequests will
8712 not try to read it twice (and block). [Roy Fielding]
8714 *) Add a placeholder in modules/Makefile to avoid errors with certain
8715 makes. [Marc Slemko]

8724 handle high numbered descriptors (examples include bind, and
8725 solaris libc). On all systems apache attempts to keep all permanent
8726 descriptors above 15 (called the low slack line). Solaris users
8727 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8728 which keeps all non-FILE * descriptors above 255. On all systems
8729 this should make supporting large numbers of vhosts with many open
8730 log files more feasible. If this causes trouble please report it,
8731 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8732 [Dean Gaudet] various PRs
8734 *) Related to the last entry, network sockets are now opened before
8735 log files are opened. The only known case where this can cause
8736 problems is under Solaris with many virtualhosts and many Listen
8737 directives. But using -DHIGH_SLACK_LINE=256 described above will
8738 work around this problem. [Dean Gaudet]

8834 Module declaration. Also, be more understanding about the
8835 CC=/OPTIM= format in Configuration. Finally, fix compiler
8836 flags if using HP-UX's cc compiler. [Jim Jagielski]
8838 *) Subrequests and internal redirects now inherit the_request from the
8839 original request-line. [Roy Fielding]
8841 *) Test for error conditions before creating output header fields, since
8842 we don't want the error message to include those fields. Likewise,
8843 reset the content_language(s) and content_encoding of the response
8844 before generating or redirecting to an error message, since the new
8845 message will have its own Content-* definitions. [Dean Gaudet]

8853 not properly checking both the value configured by the DefaultType
8854 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8855 of DEFAULT_TYPE to match the documented default (text/plain).

8861 *) Properly initialize the flock structures used by the mutex locking
8862 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8865 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8866 (and NCSA httpd) definition wherein it was the extra path info beyond
8867 the CGI script filename. The environment variable FILEPATH_INFO has
8868 been removed, and instead we supply the original REQUEST_URI to any
8869 script that wants to be Apache-specific and needs the real URI path.
8870 This solves a problem with existing scripts that use extra path info
8871 in the ScriptAlias directive to pass options to the CGI script.
8874 *) The _default_ change in 1.2b10 will change the behaviour on configs
8875 that use multiple Listen statements for listening on multiple ports.
8876 But that change is necessary to make _default_ consistent with other
8877 forms of <VirtualHost>. It requires such configs to be modified
8878 to use <VirtualHost _default_:*>. The documentation has been
8879 updated. [Dean Gaudet] PR#530
8881 *) If an ErrorDocument CGI script is used to respond to an error
8882 generated by another CGI script which has already read the message
8883 body of the request, the server would block trying to read the
8884 message body again. [Rob Hartill]

8962 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8963 parsing of headers. If the terminating empty-line CRLF occurs starting
8964 at the 256th or 257th byte of output, then Navigator will think a normal
8965 image is invalid. We are guessing that this is because their initial
8966 read of a new request uses a 256 byte buffer. We check the bytes written
8967 so far and, if we are about to tickle the bug, we instead insert a
8968 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

9044 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
9046 *) Stopgap solution for CGI 3-second delay with server-side includes: if
9047 processing a subrequest, allocate memory from r->main->pool instead
9048 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
9049 in the middle of an SSI request. [Dean Gaudet] PR #122
9051 *) Fixed status of response when POST is received for a nonexistent URL
9052 (was sending 405, now 404) and when any method is sent with a
9053 full-URI that doesn't match the server and the server is not acting
9054 as a proxy (was sending 501, now 403). [Roy Fielding]
9056 *) Host port changed to unsigned short. [Ken Coar] PR #276
9058 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
9060 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
9062 *) Report extra info from errno with many errors that cause httpd to exit.
9063 spawn_child, popenf, and pclosef now have valid errno returns in the
9064 event of an error. Correct problems where errno was stomped on
9065 before being reported. [Dean Gaudet]
9067 *) In the proxy, if the cache filesystem was full, garbage_coll() was
9068 never called, and thus the filesystem would remain full indefinitely.
9069 We now also remove incomplete cache files left if the origin server
9070 didn't send a Content-Length header and either the client has aborted
9071 transfer or bwrite() to client has failed. [Petr Lampa]
9073 *) Fixed the handling of module and script-added header fields.
9074 Improved the interface for sending header fields and reduced
9075 the duplication of code between sending okay responses and errors.
9076 We now always send both headers_out and err_headers_out, and
9077 ensure that the server-reserved fields are not being overridden,
9078 while not overriding those that are not reserved. [Roy Fielding]
9080 *) Moved transparent content negotiation fields to err_headers_out
9081 to reflect above changes. [Petr Lampa]
9083 *) Fixed the determination of whether or not we should make the
9084 connection persistent for all of the cases where some other part
9085 of the server has already indicated that we should not. Also
9086 improved the ordering of the test so that chunked encoding will
9087 be set whenever it is desired instead of only when KeepAlive
9088 is enabled. Added persistent connection capability for most error
9089 responses (those that do not indicate a bad input stream) when
9090 accessed by an HTTP/1.1 client. [Roy Fielding]
9092 *) Added missing timeouts for sending header fields, error responses,
9093 and the last chunk of chunked encoding, each of which could have
9094 resulted in a process being stuck in write forever. Using soft_timeout
9095 requires that the sender check for an aborted connection rather than
9096 continuing after an EINTR. Timeouts that used to be initiated before
9097 send_http_header (and never killed) are now initiated only within or
9098 around the routines that actually do the sending, and not allowed to
9099 propagate above the caller. [Roy Fielding]
9101 *) mod_auth_anon required an @ or a . in the email address, not both.
9104 *) per_dir_defaults weren't set correctly until directory_walk for
9105 name-based vhosts. This fixes an obscure bug with the wrong config
9106 info being used for vhosts that share the same ip as the server.
9109 *) Improved generation of modules/Makefile to be more generic for
9110 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
9112 *) Generate makefile dependency for Configuration based on the actual
9113 name given when running the Configure process. [Dean Gaudet]
9115 *) Fixed problem with vhost error log not being set prior to
9116 initializing virtual hosts. [Dean Gaudet]
9118 *) Fixed infinite loop when a trailing slash is included after a type map
9119 file URL (extra path info). [Petr Lampa]
9121 *) Fixed server status updating of per-connection counters. [Roy Fielding]
9123 *) Add documentation for DNS issues (reliability and security), and try
9124 to explain the virtual host matching process. [Dean Gaudet]
9126 *) Try to continue gracefully by disabling the vhost if a DNS lookup
9127 fails while parsing the configuration file. [Dean Gaudet]
9129 *) Improved calls to setsockopt. [Roy Fielding]
9131 *) Negotiation changes: Don't output empty content-type in variant list;
9132 Output charset in variant list; Return sooner from handle_multi() if
9133 no variants found; Add handling of '*' wildcard in Accept-Charset.
9134 [Petr Lampa and Paul Sutton]
9136 *) Fixed overlaying of request/sub-request notes and headers in
9137 mod_negotiation. [Dean Gaudet]
9139 *) If two variants' charset quality are equal and one is the default
9140 charset (iso-8859-1), then prefer the variant that was specifically
9141 listed in Accept-Charset instead of the default. [Petr Lampa]
9143 *) Memory allocation problem in push_array() -- it would corrupt memory
9144 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
9146 *) invoke_handler() doesn't handle mime arguments in content-type
9149 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
9152 *) Fixed problem with ErrorDocument not working for virtual hosts
9153 due to one of the performance changes in 1.2b7. [Dean Gaudet]
9155 *) Log an error message if we get a request header that is too long,
9156 since it may indicate a buffer overflow attack. [Marc Slemko]
9158 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
9159 not reject URLs without a double-slash, as per RFC2068 section 3.2.
9160 [Ken Coar] PR #146, #187
9162 *) Added table entry placeholder for new header_parser callback
9163 in all of the distributed modules. [Ken Coar] PR #191
9165 *) Allow for cgi files without the .EXE extension on them under OS/2.
9166 [Garey Smiley] PR #59
9168 *) Fixed error message when resource is not found and URL contains
9169 path info. [Petr Lampa and Dean Gaudet] PR #40
9171 *) Fixed user and server confusion over what should be a virtual host
9172 and what is the main server, resulting in access to something
9173 other than the name defined in the virtualhost directive (but
9174 with the same IP address) failing. [Dean Gaudet]
9176 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
9177 AIX; improves the redirection stuff to enable the users to generally
9178 redirect to http, https, gopher and ftp; added TIME variable for
9179 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
9180 special patterns >STRING, <STRING and =STRING to RewriteCond, which
9181 can be used in conjunction with %{TIME} or other variables to create
9182 time-dependent rewriting rules. [Ralf S. Engelschall]
9184 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
9185 Module authors may need to adjust their code for proper cleanup to take
9186 place (that is, call note_cleanups_for_fd()). This change fixes problems
9187 with file descriptors being erroneously closed when the proxy module was
9188 in use. [Ben Laurie]
9190 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
9191 initgroups() to hose the group information needed for later
9192 comparisons. [Randy Terbush]
9194 *) Remove unnecessary call to va_end() in create_argv() which
9195 caused a SEGV on some systems.
9197 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
9200 *) Clear memory allocated for listeners. [Randy Terbush]
9202 *) Improved handling of IP address as a virtualhost address and
9203 introduced "_default_" as a synonym for the default vhost config.
9204 [Dean Gaudet] PR #212
9206 Changes with Apache 1.2b7
9208 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
9210 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
9212 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
9213 - replace protocol response numbers with symbols
9214 - save variant-list into main request notes
9215 - free allocated memory from subrequests
9216 - merge notes, headers_out and err_headers_out
9218 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
9219 "HTTP/#.# ###*" to be more lenient about what we accept.
9222 *) more proxy FTP bug fixes:
9223 - Changed send_dir() to remove user/passwd from displayed URL.
9224 - Changed login error messages to be more descriptive.
9225 - remove setting of SO_DEBUG socket option
9226 - Make ftp_getrc() more lenient about multiline responses,
9227 specifically, 230 responses which don't have continuation 230-
9228 on each line). These seem to be all NT FTP servers, and while
9229 perhaps questionable, they appear to be legal by RFC 959.
9230 - Add missing kill_timeout() after transfer to user completes.
9233 *) Fixed problem where a busy server could hang when restarting
9234 after being sent a SIGHUP due to child processes not exiting.
9237 *) Modify mod_include escaping so a '\' only signifies an escaped
9238 character if the next character is one that needs
9239 escaping. [Ben Laurie]
9241 *) Eliminated possible infinite loop in mod_imap when relative URLs are
9242 used with a 'base' directive that does not have a '/' in it.
9243 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
9245 *) Reduced the default timeout from 1200 seconds to 300, and the
9246 one in the sample configfile from 400 to 300. [Marc Slemko]
9248 *) Stop vbprintf from crashing if given a NULL string pointer;
9249 print (null) instead. [Ken Coar]
9251 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
9252 [Marc Slemko and Roy Fielding]
9254 *) Fixed problem with mod_cgi-generated internal redirects trying to
9255 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9257 *) Reduced timeout on lingering close, removed possibility of a blocked
9258 read causing the child to hang, and stopped logging of errors if
9259 the socket is not connected (reset by client). [Roy Fielding]
9261 *) Rearranged main child loop to remove duplication of code in
9262 select/accept and keep-alive requests, fixed several bugs regarding
9263 checking scoreboard_image for exit indication and failure to
9264 account for all success conditions and trap all error conditions,
9265 prevented multiple flushes before closing the socket; close the entire
9266 socket buffer instead of just one descriptor, prevent logging of
9267 EPROTO and ECONNABORTED on platforms where supported, and generally
9268 improved readability. [Roy Fielding]
9270 *) Extensive performance improvements. Cleaned up inefficient use of
9271 auto initializers, multiple is_matchexp calls on a static string,
9272 and excessive merging of response_code_strings. [Dean Gaudet]
9274 *) Added double-buffering to mod_include to improve performance on
9275 server-side includes. [Marc Slemko]
9277 *) Several fixes for suexec wrapper. [Randy Terbush]
9278 - Make wrapper work for files on NFS filesystem.
9279 - Fix portability problem of MAXPATHLEN.
9280 - Fix array overrun problem in clean_env().
9281 - Fix allocation of PATH environment variable
9283 *) Removed extraneous blank line is description of mod_status chars.
9286 *) Logging of errors from the call_exec routine simply went nowhere,
9287 since the logfile fd has been closed, so now we send them to stderr.
9288 [Harald T. Alvestrand]
9290 *) Fixed core dump when DocumentRoot is a CGI.
9291 [Ben Laurie, reported by geddis@tesserae.com]
9293 *) Fixed potential file descriptor leak in mod_asis; updated it and
9294 http_core to use pfopen/pfclose instead of fopen/fclose.
9295 [Randy Terbush and Roy Fielding]
9297 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9298 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9299 [Dean Gaudet and Ken Coar]
9301 *) Return a 302 response code to the client when sending a redirect
9302 due to a missing trailing '/' on a directory instead of a 301; now
9303 it is cacheable. [Markus Gyger]
9305 *) Fix condition where, if a bad directive occurs in .htaccess, and
9306 sub_request() goes first to this directory, then log_reason() will
9307 SIGSEGV because it doesn't have initialized r->per_dir_config.
9308 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9310 *) Fix handling of lang_index in is_variant_better(). This was
9311 causing problems which resulted in the server sending the
9312 wrong language document in some cases. [Petr Lampa]
9314 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9315 the clean environment on some systems.
9317 *) Tweak byteserving code (e.g. serving PDF files) to work around
9318 bugs in Netscape Navigator and Microsoft Internet Explorer.
9319 Emit Content-Length header when sending multipart/byteranges.
9322 *) Port to HI-UX/WE2. [Nick Maclaren]
9324 *) Port to HP MPE operating system for HP 3000 machines
9325 [Mark Bixby <markb@cccd.edu>]
9327 *) Fixed bug which caused a segmentation fault if only one argument
9328 given to RLimit* directives. [Ed Korthof]
9330 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9332 *) Improved buffered output to the client by delaying the flush decision
9333 until the BUFF code is actually about to read the next request.
9334 This fixes a problem introduced in 1.2b5 with clients that send
9335 an extra CRLF after a POST request. Also improved chunked output
9336 performance by combining writes using writev() and removing as
9337 many bflush() calls as possible. NOTE: Platforms without writev()
9338 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9339 or Configure, unless we have already done so. [Dean Gaudet]
9341 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9343 *) Fixed mod_info output corruption bug introduced by buffer overflow
9344 fixes. [Dean Gaudet]
9346 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9347 for the special case of a 304 response. [Paul Sutton]
9349 *) Improved handling of TRACE method by bypassing normal method handling
9350 and header parsing routines; fixed Allow response to always allow TRACE.
9353 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9355 *) Cleaned-up some of the generated HTML. [Ken Coar]
9357 Changes with Apache 1.2b6
9359 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9361 *) Fix typo introduced in fix for potential infinite loop around
9362 accept() in child_main(). This change caused the rev to 1.2b6.
9363 1.2b5 was never a public beta.
9365 Changes with Apache 1.2b5
9367 *) Change KeepAlive semantics (On|Off instead of a number), add
9368 MaxKeepAliveRequests directive. [Alexei Kosut]
9370 *) Various NeXT compilation patches, as well as a change in
9371 regex/regcomp.c since that file also used a NEXT define.
9374 *) Allow * to terminate the end of a directory match in mod_dir.
9375 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9377 *) Don't call can_exec() if suexec_enabled. Calling this requires
9378 scripts executed by the suexec wrapper to be world executable, which
9379 defeats one of the advantages of running the wrapper. [Randy Terbush]
9381 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9384 *) Migration from sprintf() to snprintf() to avoid buffer
9385 overflows. [Marc Slemko]
9387 *) Provide portable snprintf() implementation (ap_snprintf)
9388 as well as *cvt family. [Jim Jagielski]
9390 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9393 *) Remove mod_fastcgi.c from the distribution. This module appears
9394 to be maintained more through the Open Market channels and should
9395 continue to be easily available at http://www.fastcgi.com/
9397 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9398 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9400 *) mod_info assumed that the config files were relative to ServerRoot.
9403 *) CGI scripts called as an error document resulting from failed
9404 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9406 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9409 *) Properly check errno to prevent display of a directory index
9410 when server receives a long enough URL to confuse stat().
9413 *) Several security enhancements to suexec wrapper. It is _highly_
9414 recommended that previously installed versions of the wrapper
9415 be replaced with this version. [Randy Terbush, Jason Dour]
9417 - ~user execution now properly restricted to ~user's home
9418 directory and below.
9419 - execution restricted to UID/GID > 100
9420 - restrict passed environment to known variables
9421 - call setgid() before initgroups() (portability fix)
9422 - remove use of setenv() (portability fix)
9424 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9426 *) Add access control via environment variables. [Ben Laurie]
9428 *) Add rflush() function. [Alexei Kosut]
9430 *) remove duplicate pcalloc() call in new_connection().
9432 *) Fix incorrect comparison which could allow number of children =
9433 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9434 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9436 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9437 AIX PS/2, CONVEXOS. [Jim Jagielski]
9439 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9440 It's more portable. [Martin Kraemer]
9442 *) Replace references to make in Makefile.tmpl with $(MAKE).
9445 *) Add ProxyBlock directive w/IP address caching. Add IP address
9446 caching to NoCache directive as well. ProxyBlock works with all
9447 handlers; NoCache now also works with FTP for anonymous logins.
9448 Still more code cleanup. [Chuck Murcko]
9450 *) Add "header parse" API hook [Ben Laurie]
9452 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9454 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9456 *) Correctly allow access and auth directives in <Files> sections in
9457 server config files. [Alexei Kosut]
9459 *) Fix bug with ServerPath that could cause certain files to be not
9460 found by the server. [Alexei Kosut]
9462 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9463 double-quote from text and so that it properly checks for unsupported
9464 status codes using the new index_of_response interface. [Roy Fielding]
9466 *) Multiple fixes to the lingering_close code in order to avoid being
9467 interrupted by a stray timeout, to avoid lingering on a connection
9468 that has already been aborted or never really existed, to ensure that
9469 we stop lingering as soon as any error condition is received, and to
9470 prevent being stuck indefinitely if the read blocks. Also improves
9471 reporting of error conditions. [Marc Slemko and Roy Fielding]
9473 *) Fixed initialization of parameter structure for sigaction.
9474 [mgyger@itr.ch, Adrian Filipi-Martin]
9476 *) Fixed reinitializing the parameters before each call to accept and
9477 select, and removed potential for infinite loop in accept.
9478 [Roy Fielding, after useful PR from adrian@virginia.edu]
9480 *) Fixed condition where, if a child fails to fork, the scoreboard would
9481 continue to say SERVER_STARTING forever. Eventually, the main process
9482 would refuse to start new children because count_idle_servers() will
9483 count those SERVER_STARTING entries and will always report that there
9484 are enough idle servers. [Phillip Vandry]
9486 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9487 Avoided calling bflush() when the client is pipelining requests.
9488 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9490 *) Added description of "." mode in server-status [Jim Jagielski]
9492 Changes with Apache 1.2b4
9494 *) Fix possible race condition in accept_mutex_init() that
9495 could leave a small security hole open allowing files to be
9496 overwritten in cases where the server UID has write permissions.
9499 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9501 *) Fix portablity problem in util_script where ARG_MAX may not be
9502 defined for some systems.
9504 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9507 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9508 style magic #! token for better script portability. [Garey Smiley]
9510 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9511 execution for ~userdir CGI. [Jason Dour]
9513 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9515 *) Fix month off by one in suexec wrapper logging.
9517 Changes with Apache 1.2b3:
9519 *) Fix error in mod_cgi which could cause resources not to be properly
9520 freed, or worse. [Dean Gaudet]
9522 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9524 *) Add set_flag_slot() at the request of Dirk and others.
9527 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9529 *) Add changes to improve the error message given for invalid
9530 ServerName parameters. [Dirk vanGulik]
9532 *) Add "Authoritative" directive for Auth modules that don't
9533 currently have it. This gives admin control to assign authoritative
9534 control to an authentication scheme and allow "fall through" for
9535 those authentication modules that aren't "Authoritative" thereby
9536 allowing multiple authentication mechanisms to be chained.
9539 *) Remove requirement for ResourceConfig/AccessConfig if not using
9540 the three config file layout. [Randy Terbush]
9542 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9544 *) Changes to suexec wrapper to fix the following problems:
9545 1. symlinked homedirs will kill ~userdirs.
9546 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9547 3. CGI command lines paramters problems
9548 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9549 [Randy Terbush, Jason Dour]
9551 *) Change create_argv() to accept variable arguments. This fixes
9552 a problem where arguments were not getting passed to the CGI via
9553 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9555 *) Collapse multiple slashes in path URLs to properly apply
9556 handlers defined by <Location>. [Alexei Kosut]
9558 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9560 *) Improve the accuracy of request duration timings by setting
9561 r->request_time in read_request_line() instead of read_request().
9564 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9565 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9567 *) Add the ability to pass different Makefile.tmpl files to Configure
9568 using the -make flag. [Rob Hartill]
9570 *) Fix coredump triggered when sending a SIGHUP to the server caused
9571 by an assertion failure, in turn caused by an uninitialised field in a
9575 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9576 PATH_INFO from previous versions of Apache (in certain situations,
9577 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9578 [later removed in 1.2b11]
9580 *) Add rwrite() function to API to allow for sending strings of
9581 arbitrary length. [Doug MacEachern]
9583 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9585 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9586 NeXT. [Jim Jagielski]
9588 *) Removed recent modification to promote the status code on internal
9589 redirects, since the correct fix was to change the default log format
9590 in mod_log_config so that it outputs the original status. [Rob Hartill]
9592 Changes with Apache 1.2b2:
9594 *) Update set_signals() to use sigaction() for setting handlers.
9595 This appears to fix a re-entrant problem in the seg_fault()
9596 bus_error() handlers. [Randy Terbush]
9598 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9600 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9602 *) proxy_http.c bugfixes: [Chuck Murcko]
9603 1) fixes possible NULL pointer reference w/NoCache
9604 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9605 host would cache nothing if it was in the local domain,
9606 and the local domain was in the NoCache list)
9607 3) Adds Host: header when not available
9608 4) Some code cleanup and clarification
9610 *) mod_include.c bugfixes:
9611 1) Fixed an ommission that caused include variables to not
9612 be parsed in config errmsg directives [Howard Fear]
9613 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9614 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9615 4) Allow backslash-escaping to all quoted text
9616 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9617 5) Pass variable to command line if not set in XSSI's env
9620 *) Fix infinite loop when processing Content-language lines in
9621 type-map files. [Alexei Kosut]
9623 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9625 *) Fixed problem in set_[user|group] that prevented CGI execution
9626 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9628 *) Added PORTING information file. [Jim Jagielski]
9630 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9632 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9634 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9635 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9637 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9638 which caused problems of systems where socket s_addr is >32bits.
9640 *) Added comment to explain (r->chunked = 1) side-effect in
9641 http_protocol.c [Roy Fielding]
9643 *) Replaced use of index() in mod_expires.c with more appropriate
9644 and portable isdigit() test. [Ben Laurie]
9646 *) Updated Configure for ...
9647 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9648 *-dg-dgux* (bad pattern match)
9649 QNX (DEF_WANTHSREGEX=yes)
9650 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9653 and added some user diagnostic info. [Ben Laurie]
9655 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9656 for better portability. [Jim Jagielski]
9658 *) Updated helpers/GuessOS for ...
9659 SCO 5 (recognize minor releases)
9660 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9661 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9662 IRIX64 (-sgi-irix64)
9663 ULTRIX (-unknown-ultrix)
9664 SINIX (-whatever-sysv4)
9665 NCR Unix (-ncr-sysv4)
9666 and fixed something in helpers/PrintPath [Ben Laurie]
9668 Changes with Apache 1.2b1
9670 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9672 Changes with Apache 1.1.1
9674 *) Fixed bug where Cookie module would make two entries in the
9675 logfile for each access [Mark Cox]
9677 *) Fixed bug where Redirect in .htaccess files would cause memory
9678 leak. [Nathan Neulinger]
9680 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9682 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9684 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9686 Changes with Apache 1.1.0
9688 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9690 *) Bring QNX support up to date. [Ben Laurie]
9692 *) Make virtual hosts default to main server keepalive parameters.
9693 [Alexei Kosut, Ben Laurie]
9695 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9697 *) Fix missing address family for connect, also remove unreachable statement
9698 in mod_proxy. [Ben Laurie]
9700 *) mod_env now turned on by default in Configuration.tmpl.
9702 *) Bugs which were fixed:
9703 a) yet more mod_proxy bugs [Ben Laurie]
9704 b) CGI works again with inetd [Alexei Kosut]
9705 c) Leading colons were stripped from passwords [osm@interguide.com]
9706 d) Another fix to multi-method Limit problem [jk@tools.de]
9708 Changes with Apache 1.1b4
9710 *) r->bytes_sent variable restored. [Robert Thau]
9712 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9714 *) More possibly unsecure programs removed from the support directory.
9716 *) More mod_auth_msql authentication improvements.
9718 *) VirtualHosts based on Host: headers no longer conflict with the
9721 *) OS/2 compatibility enhancements. [Gary Smiley]
9723 *) POST now allowed to directory index CGI scripts.
9725 *) Actions now work with files of the default type.
9727 *) Bugs which were fixed:
9728 a) more mod_proxy bugs
9729 b) early termination of inetd requests
9730 c) compile warnings on several systems
9731 d) problems when scripts stop reading output early
9733 Changes with Apache 1.1b3
9735 *) Much of cgi-bin and all of cgi-src has been removed, due to
9736 various security holes found and that we could no longer support
9739 *) The "Set-Cookie" header is now special-cased to not merge multiple
9740 instances, since certain popular browsers can not handle multiple
9741 Set-Cookie instructions in a single header. [Paul Sutton]
9743 *) rprintf() added to buffer code, occurrences of sprintf removed.
9746 *) CONNECT method for proxy module, which means tunneling SSL should work.
9747 (No crypto needed) Also a NoCache config directive.
9749 *) Several API additions: pstrndup(), table_unset() and get_token()
9750 functions now available to modules.
9752 *) mod_imap fixups, in particular Location: headers are now complete
9755 *) New "info" module which reports on installed module set through a
9756 special URL, a la mod_status.
9758 *) "ServerPath" directive added - allows for graceful transition
9759 for Host:-header-based virtual hosts.
9761 *) Anonymous authentication module improvements.
9763 *) MSQL authentication module improvements.
9765 *) Status module design improved - output now table-based. [Ben Laurie]
9767 *) htdigest utility included for use with digest authentication
9770 *) mod_negotiation: Accept values with wildcards to be treated with
9771 less priority than those without wildcards at the same quality
9772 value. [Alexei Kosut]
9774 *) Bugs which were fixed:
9775 a) numerous mod_proxy bugs
9776 b) CGI early-termination bug [Ben Laurie]
9777 c) Keepalives not working with virtual hosts
9778 d) RefererIgnore problems
9779 e) closing fd's twice in mod_include (causing core dumps on
9780 Linux and elsewhere).
9782 Changes with Apache 1.1b2
9785 a) core dumps in mod_digest
9786 b) truncated hostnames/ip address in the logs
9787 c) relative URL's in mod_imap map files
9789 Changes with Apache 1.1b1
9791 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9793 Changes with Apache 1.0.3
9795 *) Internal redirects which occur in mod_dir.c now preserve the
9796 query portion of a request (the bit after the question mark).
9799 *) Escape active characters '<', '>' and '&' in html output in
9800 directory listings, error messages and redirection links.
9803 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9805 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9808 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9810 *) Reset timeout timer after each successful fwrite() to the network.
9811 This patch adds a reset_timeout() procedure that is called by
9812 send_fd() to reset the timeout ever time data is written to the net.
9815 *) timeout() signal handler now checks for SIGPIPE and reports
9816 lost connections in a more user friendly way. [Rob Hartill]
9818 *) Location of the "scoreboard" file which used to live in /tmp is
9819 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9820 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9822 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9824 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9825 which caused a SEGV with cookies enabled
9827 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9830 *) Log the UNIX textual error returned by some system calls, in
9831 particular errors from accept() [David Robinson]
9833 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9835 Changes with Apache 1.0.2
9837 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9838 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9840 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9843 *) past changes to http_config.c to only use the
9844 setrlimit function on systems defining RLIMIT_NOFILE
9845 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9846 for SUNOS and prototypes the needed functions.
9848 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9851 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9853 *) Merge multiple headers from CGI scripts instead of taking last
9854 one. [David Robinson]
9856 *) Add support for SCO 5. [Ben Laurie]
9858 Changes with Apache 1.0.1
9860 *) Silence mod_log_referer and mod_log_agent if not configured
9863 *) Recursive includes can occur if the client supplies PATH_INFO data
9864 and the server provider uses relative links; as file.html
9865 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9867 *) The replacement for initgroups() did not call {set,end}grent(). This
9868 had two implications: if anything else used getgrent(), then
9869 initgroups() would fail, and it was consuming a file descriptor.
9872 *) On heavily loaded servers it was possible for the scoreboard to get
9873 out of sync with reality, as a result of a race condition.
9874 The observed symptoms are far more Apaches running than should
9875 be, and heavy system loads, generally followed by catastrophic
9876 system failure. [Ben Laurie]
9878 *) Fix typo in license. [David Robinson]
9880 Changes with Apache 1.0.0 23 Nov 1995
9882 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9884 Changes with Apache 0.8.16 05 Nov 1995
9886 *) New man page for 'httpd' added to support directory [David Robinson]
9888 *) .htgroup files can have more than one line giving members for a
9889 given group (each must have the group name in front), for NCSA
9890 back-compatibility [Robert Thau]
9892 *) Mutual exclusion around accept() is on by default for SVR4 systems
9893 generally, since they generally can't handle multiple processes in
9894 accept() on the same socket. This should cure flaky behavior on
9895 a lot of those systems. [David Robinson]
9897 *) AddType, AddEncoding, and AddLanguage directives take multiple
9898 extensions on a single command line [David Robinson]
9900 *) UserDir can be disabled for a given virtual host by saying
9901 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9902 that this didn't work. [David Robinson]
9904 *) Compiles on QNX [Ben Laurie]
9906 *) Corrected parsing of ctime time format [David Robinson]
9908 *) httpd does a perror() before exiting if it can't log its pid
9909 to the PidFile, to make diagnosing the error a bit easier.
9912 *) <!--#include file="..."--> can no longer include files in the
9913 parent directory, for NCSA back-compatibility. [David Robinson]
9915 *) '~' is *not* escaped in URIs generated for directory listings
9918 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9920 *) Fixed bug involving handling URIs with escaped %-characters
9921 in redirects [David Robinson]
9923 Changes with Apache 0.8.15 14 Oct 1995
9925 *) Switched to new, simpler license
9927 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9929 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9931 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9933 *) Correctly handles internal redirects to files with names containing '%'
9936 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9938 *) Use geteuid() rather than getuid() to see if we have root privilege,
9939 so that server correctly resets privilege if run setuid root. [Andrew
9942 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9945 *) Fix relative URLs in imagemap files [Randy Terbush]
9947 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9950 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9951 entries all name the same one. [David Robinson]
9953 *) Fix directory listings with filenames containing unusual characters
9956 *) Better URI-escaping for generated URIs in directories with filenames
9957 containing unusual characters [Ben Laurie]
9959 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9961 *) Unblock alarms on error return from spawn_child() [David Robinson]
9963 *) Sample Config files have extra note for SCO users [Ben Laurie]
9965 *) Configuration has note for HP-UX users [Rob Hartill]
9967 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9969 *) Nuked bogus #define in httpd.h [David Robinson]
9971 *) Better test for whether a system has setrlimit() [David Robinson]
9973 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9975 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9978 Changes with Apache 0.8.14 19 Sep 1995
9980 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9982 *) AddDescription works (better) [Ben Laurie]
9984 *) Leaves an intelligible error diagnostic when it can't set group
9985 privileges on standalone startup [Andrew Wilson]
9987 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9988 that machine, which claims to be BSD but does not support RLIMIT.
9991 *) gcc -Wall no longer complains about an unused variable when util.c
9992 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9994 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9996 Changes with Apache 0.8.13 07 Sep 1995
9998 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
10000 *) Have built-in imagemap code recognize & honor Point directive [James
10003 *) Generate cleaner directory listings in directories with a mix of
10004 long and short filenames [Rob Hartill]
10006 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
10008 *) Properly default ServerName for virtual servers [Robert Thau]
10010 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
10011 Paul Richards and a cast of thousands...]
10013 *) On self-identified BSD systems (we don't try to guess any more),
10014 allocate a few extra file descriptors per virtual host with setrlimit,
10015 if we can, to avoid running out. [Randy Terbush]
10017 *) Write 22-character lock file name into buffer with enough space
10018 on startup [Konstantin Olchanski]
10020 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
10023 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
10025 *) Suppress -Wall warning by initializing variable in negotiation code
10026 [Tobias Weingartner]
10028 Changes with Apache 0.8.12 31 Aug 1995
10030 *) Doesn't pause three seconds after including a CGI script which is
10031 too slow to die off (this is done by not even trying to kill off
10032 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
10033 after the entire document has been processed). [Robert Thau]
10035 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
10037 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
10039 *) Allows .htaccess files to override <Directory> sections naming the
10040 same directory [David Robinson]
10042 *) Removed an efficiency hack in sub_req_lookup_uri which was
10043 causing certain extremely marginal cases (e.g., ScriptAlias of a
10044 *particular* index.html file) to fail. [David Robinson]
10046 *) Doesn't log an error when the requested URI requires
10047 authentication, but no auth header line was supplied by the
10048 client; this is a normal condition (the client doesn't no auth is
10049 needed here yet). [Robert Thau]
10051 *) Behaves more sanely when the name server loses its mind [Sean Welch]
10053 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
10055 *) RFC931 code no longer passes out name of prior clients on current
10056 requests if the current request came from a server that doesn't
10057 do RFC931. [David Robinson]
10059 *) Configuration script accepts "Module" lines with trailing whitespace.
10062 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
10064 *) Cleaned up comments in mod_cgi.c [Robert Thau]
10066 Changes with Apache 0.8.11 24 Aug 1995
10068 *) Wildcard <Directory> specifications work. [Robert Thau]
10070 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
10072 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
10073 the file being requested itself, in addition to the directories leading
10074 up to it. [Robert Thau]
10076 *) Logs access failures due to symlink checks or invalid client address
10077 in the error log [Roy Fielding, Robert Thau]
10079 *) Symlink checks deal correctly with systems where lstat of
10080 "/path/to/some/link/" follows the link. [Thau, Fielding]
10082 *) Doesn't reset DirectoryIndex to 'index.html' when
10083 other directory options are set in a .htaccess file. [Robert Thau]
10085 *) Clarified init code and nuked bogus warning in mod_access.c
10086 [Florent Guillaume]
10088 *) Corrected several directives in sample srm.conf
10089 --- includes corrections to directory indexing icon-related directives
10090 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
10091 icons for encodings right, and turning on AddEncoding by default).
10094 *) Corrected descriptions of args to AddIcon and AddAlt in command table
10097 *) INSTALL & README mention "contributed modules" directory [Brian
10100 *) Fixed English in the license language... "for for" --> "for".
10103 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
10104 mod_alias.c, merging it almost completely with handling of Alias, and
10105 adding a 'notes' field to the request_rec which allows the CGI module
10106 to discover whether the Alias module has put this request through
10107 ScriptAlias (which it needs to know for back-compatibility, as the old
10108 NCSA code did not check Options ExecCGI in ScriptAlias directories).
10111 Changes with Apache 0.8.10 18 Aug 1995
10113 *) AllowOverride applies to the named directory, and not just
10114 subdirectories. [David Robinson]
10116 *) Do locking for accept() exclusion (on systems that need it)
10117 using a special file created for the purpose in /usr/tmp, and
10118 not the error log; using the error log causes real problems
10119 if it's NFS-mounted; this is known to be the cause of a whole
10120 lot of "server hang" problems with Solaris. [David Robinson;
10121 thanks to Merten Schumann for help diagnosing the problem].
10123 Changes with Apache 0.8.9 12 Aug 1995
10125 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
10127 *) Nested includes see environment variables of the including document,
10128 for NCSA bug-compatibility (some sites have standard footer includes
10129 which try to print out the last-modified date). [Eric Hagberg/Robert
10132 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
10133 URI as a CGI script, even if it would have been treated as something
10134 else if requested directly, for NCSA back-compatibility. (Note that
10135 this means that people who know the name of the script can see the
10136 code just by asking for it). [Robert Thau]
10138 *) New version of dbmmanage script included in support directory as
10141 *) Check if scoreboard file couldn't be opened, and say so, rather
10142 then going insane [David Robinson]
10144 *) POST to CGI works on A/UX [Jim Jagielski]
10146 *) AddIcon and AddAlt commands work properly [Rob Hartill]
10148 *) NCSA server push works properly --- the Arena bug compatibility
10149 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
10150 if you still want the workaround). [Rob Hartill]
10152 *) If client didn't submit any Accept-encodings, ignore encodings in
10153 content negotiation. (NB this will all have to be reworked anyway
10154 for the new HTTP draft). [Florent Guillaume]
10156 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
10158 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
10160 *) Give Redirect priority over Alias, for NCSA bug compatibility
10163 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
10164 paralleling earlier bug fix for CGI [David Robinson]
10166 *) If DBM auth is improperly configured, report a server error and don't
10169 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
10170 it seems to work well enough without it (even in a 10 hits/sec
10171 workout), and the overhead for the locking under A/UX is
10172 alarmingly high (though it is very low on other systems).
10173 [Eric Hagberg, Jim Jagielski]
10175 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
10177 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
10178 Behlendorf/Eric Hagberg]
10180 *) More improvements to default Configuration for A/UX [Jim Jagielski]
10182 *) Compiles clean on NEXT [Rob Hartill]
10184 *) Compiles clean on SGI [Robert Thau]
10186 Changes with Apache 0.8.8 08 Aug 1995
10188 *) SunOS library prototypes now never included unless explicitly
10189 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
10190 people using GNU libc on SunOS are screwed by prototypes for the
10193 (Those who wish to compile clean with gcc -Wall on a standard
10194 SunOS setup need the prototypes, and may obtain them using
10195 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
10196 with nonstandard libraries are presumably competent to make their
10199 *) Strips trailing '/' characters off both args to the Alias command,
10200 to make 'Alias /foo/ /bar/' work.
10202 Changes with Apache 0.8.7 03 Aug 1995
10204 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
10205 [reported by David Robinson]
10207 *) Compiles clean on OSF/1 [David Robinson]
10209 *) Added some of the more recent significant changes (AddLanguage stuff,
10210 experimental LogFormat support) to CHANGES file in distribution root
10213 Changes with Apache 0.8.6 02 Aug 1995
10215 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10216 (If you actually wanted a conditional GET which bypassed the cache, you
10217 couldn't get it). [Reported by Roy Fielding]
10219 *) Properly terminate headers on '304 Not Modified' replies to conditional
10220 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10221 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10223 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10225 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10226 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10227 and older versions don't set the __SUNPRO_C preprocessor variable). On
10228 all other systems, these are never used anyway. [Reported by Mark Cox].
10230 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10232 Changes with Apache 0.8.5 01 Aug 1995
10234 *) Added last-minute configurable log experiment, as optional module
10236 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10237 properly. (One-line fix to http_protocol.c).
10239 *) Work around bogus behavior when reloading from Netscape.
10240 It's Netscape's bug --- for some reason they expect a request with
10241 If-modified-since: to not function as a conditional GET if it also
10242 comes with Pragma: no-cache, which is way out of line with the HTTP
10243 spec (according to Roy Fielding, the redactor).
10245 *) Added parameter to set maximum number of server processes.
10247 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10250 *) IdentityCheck bugfix [Chuck Murcko].
10252 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10254 *) More sample config file corrections; add extension to AddType for
10255 *.asis, move AddType generic description to its proper place, and
10256 fix miscellaneous typos. [ Alexei Kosut ]
10258 *) Deleted the *other* reference to the regents from the Berkeley
10259 legal disclaimer (everyplace).
10261 *) Nuked Shambhala name from src/README; had already cleaned it out
10262 of everywhere else.
10264 Changes with Apache 0.8.4
10266 *) Changes to server-pool management parms --- renamed current
10267 StartServers to MinSpareServers, created separate StartServers
10268 parameter which means what it says, and renamed MaxServers to
10269 MaxSpareServers (though the old name still works, for NCSA 1.4
10270 back-compatibility). The old names were generally regarded as
10271 too confusing. Also altered "docs" in sample config files.
10273 *) More improvements to default config files ---
10274 sample directives (commented out) for XBitHack, BindAddress,
10275 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10276 defaults, AddTypes for send-as-is and imagemap magic types, and
10277 improvements to samples for DirectoryIndex [Alexei Kosut]
10279 *) Yet more improvements to default config files --- changes to
10280 Alexei's sample AddLanguage directives, and sample LanguagePriority
10281 [ Florent Guillaume ]
10283 *) Set config file locations properly if not set in httpd.conf
10286 *) Don't escape URIs in internal redirects multiple times; don't
10287 do that when translating PATH_INFO to PATH_TRANSLATED either.
10290 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10292 Changes with Apache 0.8.3
10294 *) Edited distribution README to *briefly* summarize installation
10295 procedures, and give a pointer to the INSTALL file in the src/
10298 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10299 recent NCSA distributions.
10301 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10302 exist for the same directory, use both and don't segfault. [Reported
10305 *) Proper makefile dependencies [David Robinson]
10307 *) Note (re)starts in error log --- reported by Rob Hartill.
10309 *) Only call no2slash() after get_path_info() has been done, to
10310 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10311 reported by Andrew Wilson, though this one is probably a real bug]
10313 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10314 dump core when Referer is not supplied. [Randy Terbush]
10316 *) Lightly edited sample config files to refer people to our documentation
10317 instead of NCSA's, and to list Rob McCool as *original* author (also
10318 deleted his old, and no doubt non-functional email address). Would be
10319 nice to have examples of new features...
10321 Changes with Apache 0.8.2 19 Jul 1995
10323 *) Added AddLanuage code [Florent Guillaume]
10325 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10327 *) All sorts of problems when MultiViews finds a directory. It would
10328 be nice if mod_dir.c was robust enough to handle that, but for now,
10329 just punt. [reported by Brian Behlendorf]
10331 *) Wait for all children on restart, to make sure that the old socket
10332 is gone and we can reopen it. [reported by Randy Terbush]
10334 *) Imagemap module is enabled in default Configuration
10336 *) RefererLog and UserAgentLog modules properly default the logfile
10339 *) Mark Cox's mod_cookies added to the distribution as an optional
10340 module (commented out in the default Configuration, and noted as
10341 an experiment, along with mod_dld). [Mark Cox]
10343 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10345 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10347 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10349 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10352 Changes with Apache 0.8.1
10354 *) New imagemap module [Randy Terbush]
10356 *) Replacement referer log module with NCSA-compatible RefererIgnore
10357 [Matthew Gray again]
10359 *) Don't mung directory listings with very long filenames.
10360 [Florent Guillaume]
10362 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10364 *) New config script. See INSTALL for info. [Robert Thau]
10366 *) Scoreboard mechanism for regulating the number of extant server
10367 processes. MaxServers and StartServers defaults are the same as
10368 for NCSA, but the meanings are slightly different. (Actually,
10369 I should probably lower the MaxServers default to 10).
10371 Before asking for a new connection, each server process checks
10372 the number of other servers which are also waiting for a
10373 connection. If there are more than MaxServers, it quietly dies
10374 off. Conversely, every second, the root, or caretaker, process
10375 looks to see how many servers are waiting for a new connection;
10376 if there are fewer than StartServers, it starts a new one. This
10377 does not depend on the number of server processes already extant.
10378 The accounting is arranged through a "scoreboard" file, named
10379 /tmp/htstatus.*, on which each process has an independent file
10380 descriptor (they need to seek without interference).
10382 The end effect is that MaxServers is the maximum number of
10383 servers on an *inactive* server machine, but more will be forked
10384 off to handle unusually heavy loads (or unusually slow clients);
10385 these will die off when they are no longer needed --- without
10386 reverting to the overhead of full forking operation. There is a
10387 hard maximum of 150 server processes compiled in, largely to
10388 avoid forking out of control and dragging the machine down.
10389 (This is arguably too high).
10391 In my server endurance tests, this mechanism did not appear to
10392 impose any significant overhead, even after I forced it to put the
10393 scoreboard file on a normal filesystem (which might have more
10394 overhead than tmpfs). [Robert Thau]
10396 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10399 *) Read .htaccess files even in directory with <Directory> section.
10400 (Former incompatibility noted on mailing list, now fixed). [Robert
10403 *) "HEAD /" gives the client a "Bad Request" error message, rather
10404 than trying to send no body *and* no headers. [Cliff Skolnick].
10406 *) Don't produce double error reports for some very obscure cases
10407 mainly involving auth configuration (the "all modules decline to
10408 handle" case which is a sure sign of a server bug in most cases,
10409 but also happens when authentication is badly misconfigured).
10412 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10413 it's *for*, and this sort of thing really shouldn't be cluttering
10414 up the Makefile). [Robert Thau]
10416 *) Incidental code cleanups in http_main.c --- stop dragging
10417 sa_client around; just declare it where used. [Robert Thau]
10419 *) Another acc-related fix. (It doesn't like const char
10420 in some places...). [Mark Cox]
10422 Changes with Shambhala 0.6.1 13 Jul 1995
10424 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10425 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10427 *) Compiles clean with acc on SunOS [Paul Sutton]
10429 *) Reordered modules in modules.c so that Redirect takes priority
10430 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10431 believe it or not, he has an actual site with a ScriptAlias and
10432 a Redirect declared for the *exact same directory*. Even *my*
10433 compatibility fetish wouldn't motivate me to fix this if the fix
10434 required any effort, but it doesn't, so what the hey.
10436 *) Fixed to properly default several server_rec fields for virtual
10437 servers from the corresponding fields in the main server_rec.
10438 [Cliff Skolnick --- 'port' was a particular irritant].
10440 *) No longer kills off nph- child processes before they are
10441 finished sending output. [Matthew Gray]
10443 Changes with Shambhala 0.6.0 10 Jul 1995
10445 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10446 the connection to the client in an "aborted" state, but otherwise
10447 allow whatever handlers are running to clean up. hard_timeout()s
10448 abort the request in progress completely; anything not tied to some
10449 resource pool cleanup will leak. They're still around because I
10450 haven't yet come up with a more elegant way of handling
10451 timeouts when talking to something that isn't the client. The
10452 default_handler and the dir_handler now use soft timeouts, largely
10453 so I can test the feature. [Robert Thau]
10455 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10456 the case of log handlers dying prematurely is probably handled VERY
10457 gracelessly at this point, and if the logger stops reading input,
10458 the server will hang. (It is known to correctly restart the
10459 logging process on server restart; this is (should be!) going through
10460 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10461 script). [Robert Thau]
10463 *) asis files supported (new module). [Robert Thau]
10465 *) IdentityCheck code is compiled in, but has not been tested. (I
10466 don't know anyone who runs identd). [Robert Thau]
10468 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10469 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10471 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10473 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10474 as timeouts are not in scope. [Robert Thau]
10476 *) quoted-string args in config files now handled correctly (doesn't drop
10477 the last character). [Robert Thau; reported by Randy Terbush]
10479 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10480 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10482 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10483 default default type); the former default default behavior when all
10484 type-checkers defaulted had been a core dump. [Paul Sutton]
10486 *) Copy filenames out of the struct dirent when indexing
10487 directories. (On Linux, readdir() returns a pointer to the same
10488 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10490 Changes with Shambhala 0.5.3 [not released]
10492 *) Default response handler notes "file not found" in the error log,
10493 if the file was not found. [Cliff Skolnick].
10495 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10496 code no longer sets up bogus PATH_INFO which fakes out the directory
10497 handler). [Cliff Skolnick]
10499 Changes with Shambhala 0.5.2 06 Jul 1995
10501 *) Changes to http_main.c --- root server no longer plays silly
10502 games with SIGCHLD, and so now detects and replaces dying
10503 children. Child processes just die on SIGTERM, without taking
10504 the whole process group with them. Potential problem --- if any
10505 child process refuses to die, we hang in restart.
10506 MaxRequestsPerChild may still not work, but it certainly works
10507 better than it did before this! [Robert Thau]
10509 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10510 work (or work better, at least); over-long description lines
10511 properly terminated. [Mark Cox]
10513 *) http_request.c now calls unescape_url() more places where it
10514 should [Paul Sutton].
10516 *) More directory handling bugs (reported by Cox)
10517 Parent Directory link is now set correctly. [Robert Thau]
10519 Changes with Shambhala 0.5.1 04 Jul 1995
10521 *) Generalized cleanup interface in alloc.c --- any function can be
10522 registered with alloc.c as a cleanup for a resource pool;
10523 tracking of files and file descriptors has been reimplemented in
10524 terms of this interface, so I can give it some sort of a test.
10527 *) More changes in alloc.c --- new cleanup_for_exec() function,
10528 which tracks down and closes all file descriptors which have been
10529 registered with the alloc.c machinery before the server exec()s a
10530 child process for CGI or <!--#exec-->. CGI children now get
10531 started with exactly three file descriptors open. Hopefully,
10532 this cures the problem Rob H. was having with overly persistent
10533 CGI connections. [Robert Thau]
10535 *) Mutual exclusion around the accept() in child_main() --- this is
10536 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10537 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10538 This uses fcntl(F_SETLK,...) on the error log descriptor because
10539 flock() on that descriptor won't work on systems which have BSD
10540 flock() semantics, including (I think) Linux 1.3 and Solaris.
10542 This does work on SunOS (when the server is idle, only one
10543 process in the pool is waiting on accept()); it *ought* to work
10544 on the other systems. [Robert Thau]
10546 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10548 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10550 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10552 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10553 be unnecessary if I go to the revised timeout-handling scheme).
10556 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10557 string) even if none came in with the request. [Robert Thau]
10559 *) CHANGES file added to distribution ;-).
10561 Changes with Shambhala 0.4.5
10563 *) mod_dld --- early dynamic loading support [rst]
10564 *) Add wildcard content handlers for XBITHACK; default_hander now
10565 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10566 *) XBITHACK supported as a wildcard content-handler, and
10567 configurable at run-time (not just at compile time, as in the
10568 "patchy server" releases) [rst]
10570 Changes with Shambhala 0.4.4 30 Jun 1995
10572 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10573 *) Handle Addtype x/y .z [rst, reported by Cox]
10575 Changes with Shambhala 0.4.3
10577 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10578 synonymous [rst, terbush]
10580 Changes with Shambhala 0.4.1 28 Jun 1995
10582 *) First-cut virtual host implementation; some refit in the config
10583 reading code, and log management, was necessary to support this [rst]
10584 *) Sub-pool machinery, originally added to avoid excessive storage
10585 allocation on listings of large directories (which turned out to
10586 be the problem that the 0.3 storage accounting was added to
10587 find). Subrequests and mod_dir changed to use subpools. [rst]
10588 *) More memory debugging --- free list consistency checks. [rst]
10589 *) Added err_headers to request_rec, with support elsewhere [rst]
10590 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10592 Changes with Shambhala 0.3 19 Jun 1995
10594 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10595 *) Don't compile in mod_ai_backcompat by default
10596 *) Switch name of server from Apache to Shambhala in Makefile
10597 *) Add some accounting routines to track memory usage in the pools,
10600 Changes with Shambhala 0.2
10602 *) Set DOCUMENT_ROOT CGI variable
10603 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10604 *) Add critical section protection to handling of cleanup structures
10606 *) Significant code reorg within the server core to group related
10607 functions together [rst]
10608 *) Correctly handle clients that hang up before sending any request
10610 *) Replace dying child processes. [rst]
10612 Changes with Shambhala 0.1 12 Jun 1995
10614 Major rewrite of the pre-existing "patchy server" codebase, by
10615 Robert Thau (rst). Significant portions of the server code, such
10616 as configuration-file handling and HTTP authentication support,
10617 were ripped out and rewritten from scratch. Code that was not
10618 completely rewritten was significantly altered.
10620 Major changes with this release include:
10622 *) Introduction of the module API; in request handling, the central
10623 machinery just dispatches to various modules, which actually do
10624 most of the work. Configuration handling is similar --- modules
10625 declare their own commands, and the central machinery just
10626 dispatches to them.
10628 API features from shambhala/0.1 were substantially unchanged in
10629 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10630 release, such as wildcard handlers and subpools, were added in
10631 subsequent Shambhala releases, and were also generally rst's
10634 *) This release included the following modules:
10636 mod_access (access control --- allow and deny directives),
10637 mod_alias (Alias and Redirect commands),
10638 mod_auth (straight HTTP authentication, based on flat-files)
10639 mod_auth_dbm (same, with dbm files)
10640 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10641 mod_common_log (CLF access logs; later renamed mod_log_common)
10642 mod_dir (directory indexing)
10643 mod_include (server-side includes)
10644 mod_mime (AddType directives)
10645 mod_negotiation (content negotiation)
10646 mod_userdir (support for users' public_html directories)
10648 It also included a mod_ai_backcompat, which was a private hack
10649 for back-compatibility with rst's own AI-lab servers.
10651 All of these modules were substantially complete, and functional
10652 or nearly so (a few, which implemented features not in use at
10653 Thau's site, required patches of a few lines).
10655 *) sub-request machinery, to allow modules to determine how other
10656 modules would assign MIME types to a given file, or optionally
10657 serve its content (this is heavily used by mod_dir, mod_include
10658 and mod_negotiation).
10660 *) Resource pool system for keeping track of memory allocated and
10661 files opened in service of a particular request. Much of the
10662 code in the modules (when they weren't rewrites) was adjusted to
10663 replace a pervasive convention of using fixed-size buffers on
10664 the stack with an equally pervasive convention of using memory
10665 allocated with palloc().
10667 *) Reorganization of data structures associated with a given
10668 request to eliminate use of global variables and the troublesome
10669 unmunge_name function (used in NCSA and early Apache releases to
10670 attempt to determine the URI which mapped to a given filename
10671 --- a difficult proposition, given that it is easy to produce
10672 setups in which multiple URIs map to the same file).
10674 *) Source files renamed and rearranged
10676 *) Very simple pre-forking behavior --- parent process forked off a
10677 fixed number of children, and then just waited for SIGHUP.
10679 *) Other more minor changes too numerous to list.
10681 This release included modified versions of a lot of code from the
10682 Apache 0.6.4 public release, plus an early pre-forking patch
10683 codeveloped by Robert Thau and Rob Hartill.
10685 Changes with Apache 0.7.3 20 Jun 1995
10687 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10688 were incorporated by Rob Hartill on the main branch while Robert Thau
10689 worked on the Shambhala rewrite above. Most were merged into the
10690 Shambala architecture after Apache 0.8.0.
10692 Changes with Apache 0.6.4 13 May 1995
10694 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10697 Changes with Apache 0.5.1 10 Apr 1995
10699 Changes with Apache 0.4 02 Apr 1995
10701 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10704 Changes with Apache 0.3 24 Mar 1995
10706 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10709 Changes with Apache 0.2 18 Mar 1995
10711 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10712 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10713 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
