1 Changes with Apache 2.0.30-dev
3 *) The worker MPM now respects the LockFile setting, needed to
4 avoid locking problems with NFS. [Jeff Trawick]
6 *) Fix segfault when worker MPM receives SIGHUP.
7 [Ian Holsman, Aaron Bannert, Justin Erenkrantz]
9 *) Fix bug that could potentially prevent the perchild MPM from
10 working with more than one vhost/uid. [Aaron Bannert]
12 *) Change make install and apxs -i processing of DSO modules to
13 perform special handling on platforms where libtool doesn't install
14 mod_foo.so. This fixes some wonkiness on HP-UX, Tru64, and AIX
15 which prevented standard LoadModule statements from working.
18 *) Whenever mod_so is enabled (not just when there are DSOs for
19 our modules), do whatever special magic is required for compiling/
20 loading third-party modules. This allows third-party DSOs to
21 be used on an AIX build when there were no built-in modules
22 built as DSOs. (This should help on OS/390 and BeOS as well.)
25 *) Allow apxs to be used to build DSOs on AIX without requiring the
26 user to hard-code the list of import files. (This should help
27 on OS/390 and BeOS as well.) [Jeff Trawick]
29 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
30 PR 8563, 8919 [William Rowe]
32 *) Get binary builds working when libapr and libaprutil are built
35 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
36 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
37 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
39 *) Fix the handling of SSI directives in which the ">" of the
40 terminating "-->" is the last byte in a file [Brian Pane]
42 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
43 message that we had back in apache-1.3 and still have scattered
44 throughout our docs. [Aaron Bannert]
46 *) Prevent the Win32 port from continuing after encountering an
47 error in the command line args to apache. [William Rowe]
49 *) On a error in the proxy, make it write a line to the error log
52 Changes with Apache 2.0.29
54 *) Add buffering in core_output_filter to ensure that long
55 lists of small buckets don't cause small packet writes.
56 [Brian Pane, Ryan Bloom]
58 *) Fix the installation target to make sure that the manual is
59 installed in the correct location.
60 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
61 Gomez Henri <hgomez@slib.fr>]
63 *) Fix the cmd command for mod_include. When we are processing
64 a cmd command, we do not want to use the r->filename to set
65 the command name. The command comes from the SSI tag. To do this,
66 I added a variable to the function that builds the command line
67 in mod_cgi. This allows the include_cmd function to specify
68 the command line itself. [Ryan Bloom]
70 *) Change open_logs hook to return a value, allowing you
71 to flag a error while opening logs
72 [Ian Holsman, Doug MacEachern]
74 *) Change post_config hook to return a value, allowing you
75 to flag a error post config
76 [Ian Holsman, Jeff Trawick]
78 *) Allow SUEXEC_BIN (the path to the suexec binary that is
79 hard-coded into the server) to be specified to the configure
80 script by the --with-suexec-bin parameter. [Aaron Bannert]
82 *) Fix segv in worker MPM following accept on pipe-of-death
85 *) Add mod_deflate to experimental.
86 [Ian Holsman, Justin Erenkrantz]
88 *) Bail out at configure time if an invalid MPM was specified.
89 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
91 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
92 configured [John Sterling <sterling@covalent.net>]
94 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
96 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
98 *) Optimization for the BNDM string-search function in
99 mod_include. [Brian Pane]
101 *) Fixed the behavior of the XBitHack directive.
102 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
104 *) The threaded MPM for Unix has been removed. Use the worker
105 MPM instead. [various]
107 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
108 in logging the error from a failed DNS lookup. [Jeff Trawick]
110 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
113 *) Get mod_cgid killed when a MPM exits due to a fatal error.
116 *) Fix a file descriptor leak in mod_include. When we include a
117 file, we use a sub-request, but we didn't destroy the sub-request
118 immediately, instead we waited until the original request was
119 done. This patch closes the sub-request as soon as the data is
120 done being generated. [Brian Pane <bpane@pacbell.net>]
122 *) Allow modules that add sockets to the ap_listeners list to
123 define the function that should be used to accept on that
124 socket. Each MPM can define their own function to use for
125 the accept function with the MPM_ACCEPT_FUNC macro. This
126 also abstracts out all of the Unix accept error handling
127 logic, which has become out of synch across Unix MPMs.
130 *) Fix a bug which would cause the response headers to be omitted
131 when sending a negotiated ErrorDocument because the required
132 filters were attached to the wrong request_rec.
133 [John Sterling <sterling@covalent.net>]
135 *) Remove commas from the end of the macros that define
136 directives that are used by MPMs. Prior to this patch,
137 you would use these macros without commas, which was unlike
138 the macros for any other directives. Now, the caller provides
139 the comma rather than the macro providing it. This makes
140 the macros look more like the rest of the directives.
141 [Ryan Bloom and Cliff Woolley]
143 *) Add 'redirect-carefully' environment option to disable sending
144 redirects under special circumstances. This is helpful for
145 Microsoft's WebFolders when accessing a directory resource via
146 DAV methods. [Justin Erenkrantz]
148 *) Begin to abstract out the underlying transport layer.
149 The first step is to remove the socket from the conn_rec,
150 the server now lives in a context that is passed to the
151 core's input and output filters. This forces us to be very
152 careful when adding calls that use the socket directly,
153 because the socket isn't available in most locations.
156 *) Really reset the MaxClients value in worker and threaded
157 when the configured value is not a multiple of the number
158 of threads per child. We said we did previously but we
159 forgot to. [Jeff Trawick]
161 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
163 *) If shared modules are requested and mod_so is not available,
164 produce a fatal config-time error. [Justin Erenkrantz]
166 *) Improve http2env's performance by cutting the work it has to
167 do. [Brian Pane <bpane@pacbell.net>]
169 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
170 [Brian Pane <bpane@pacbell.net>]
172 Changes with Apache 2.0.28
174 *) Fix infinite loop in mod_cgid.c.
175 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
177 *) When no port is given in a "ServerName host" directive, the
178 server_rec->port is now set to zero, not 80. That allows for
179 run-time deduction of the correct server port (depending on
180 SSL/plain, and depending also on the current setting of
181 UseCanonicalName). This change makes redirections
182 work, even with https:// connections. As in Apache-1.3, the
183 connection's actual port number is never used, only the ServerName
184 setting or the client's Host: setting. Documentation updated
185 to reflect the change. [Martin Kraemer]
187 *) Add a '%{note-name}e' argument to mod-headers, which works in
188 the same way as mod_log_confg. [Ian Holsman]
190 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
191 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
192 MPMs. [Cliff Woolley]
194 *) Introduce htdbm, a user management utility for db/dbm authorization
195 databases. [Mladen Turk <mturk@mappingsoft.com>]
197 *) Optimize usage of strlen and strcat in ap_directory_walk.
198 [Brian Pane <bpane@pacbell.net>]
200 Changes with Apache 2.0.27
202 *) Introduce an Apache mod_ssl initial configuration template
203 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
205 *) Fixed a memory leak in the getline parsing code that could
206 be triggered by arbitrarily large header lines. Requests
207 from the core input filter for single lines are now limited
208 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
210 *) Fix a truncation bug in how we print the port on the Via: header.
211 The routine that prints the Via: header now takes a length for
212 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
214 *) Some syntax errors in mod_mime_magic's magic file can result
215 in a 500 error, which previously was unlogged. Now we log the
216 error. [Jeff Trawick]
218 *) Add the support/checkgid helper app, which checks the run-time
219 validity of group identifiers usable in the Group directive.
222 *) Various --enable-so options have been fixed: --enable-so is
223 treated as "static"; explicit --enable-so=shared issues an error;
224 and explicit --enable-so fails with error on systems without
225 APR_HAS_DSO. [Aaron Bannert]
227 *) Fix a segfault in the core input filter when the client socket
228 gets disconnected unexpectedly. [Cliff Woolley]
230 *) Fix the reporting for child processes that die. This removes
231 all of the non-portable W* macros from Apache.
232 [Jeff Trawick and Ryan Bloom]
234 *) Win32: Track and display "Parent Server Generation:" in
235 mod_status output. The generation will be bumped at
236 server graceful restart, when the child process exits
237 by hitting MaxRequestsPerChild or if the child
238 process exits abnormally. [Bill Stoddard]
240 *) Win32: Fix problem where MaxRequestsPerChild directive was
241 not being picked up in favor of the default. Enable
242 the parent to start up a new child process immediately upon
243 the old child starting shutdown.
246 *) Fix some bungling of the remote port in rfc1413.c so that
247 IdentityCheck retrieves the proper user id instead of failing
248 and thus always returning "nobody."
249 [Dick Streefland <Dick.Streefland@xs4all.nl>]
251 *) Introduced thread saftey for mod_rewrite's internal cache.
252 [Brian Pane <bpane@pacbell.net>]
254 *) Simplified mod_env's directives to behave as most directives are
255 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
256 directive following that UnsetEnv within the same container.
257 Also provides a runtime startup warning if a PassEnv configured
258 environment value is undefined. [William Rowe]
260 *) The worker MPM is now completely ported to APR's new lock API. It
261 uses native APR types for thread mutexes, cross-process mutexes,
262 and condition variables. [Aaron Bannert]
264 *) Sync up documentation to remove all references to the now deprecated
265 Port directive. [Justin Erenkrantz]
267 *) Moved all ldap modules from the core to httpd-ldap sub-project
270 *) Exit when we can't listen on any of the configured ports. This
271 is the same behavior as 1.3, and it avoids having the MPMs to
272 deal with bogus ap_listen_rec structures. [Jeff Trawick]
274 *) Cleanup the proxy code that creates a request to the origin
275 server. This change adds an optional hook, which allows modules
276 to gain control while the request is created if the proxy module
277 is loaded. The purpose of this hook is to allow modules to add
278 input and/or output filters to the request to the origin. While
279 I was at it, I made the core use this hook, so that proxy request
280 creation uses some of the code from the core. This can still be
281 greatly improved, but this is a good start. [Ryan Bloom]
283 Changes with Apache 2.0.26
285 *) Port the MaxClients changes from the worker MPM to the threaded
288 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
289 with the new input filtering system. [Justin Erenkrantz]
291 *) Introduce the MultiviewsMatch directive, to allow the operator
292 to be flexible in recognizing Handlers and Filters filename
293 extensions as part of the Multiviews matching logic, strict with
294 MultiviewsMatch NegotiatedOnly to accept only filename extentions
295 that designate negotiated parameters, (content type, charset, etc.)
296 or MultiviewsAll for the 1.3 behavior of matching any files, even
297 if they have unregistered extensions. [William Rowe]
299 *) Fixed the configure script to add a LoadModule directive to
300 the default httpd.conf for any module that was compiled
301 as a DSO. [Aaron Bannert <aaron@clove.org>]
303 *) rewrite mod_ssl input filtering to work with the new input filtering
304 system. [Justin Erenkrantz]
306 *) prefork: Don't segfault when we are able to listen on some but
307 not all of the configured ports. [Jeff Trawick]
309 *) Build mod_so even if no core modules are built shared.
310 [Aaron Bannert <aaron@clove.org>]
312 *) Introduce ap_directory_walk rewrite (with further optimizations
313 required) to adapt to the ap_process_request_internal() changes.
314 Optimized so subrequests and redirects now reuse previous section
315 merges, until we mismatch with the original directory_walk, and
316 precomputed r->finfo results will cause directory_walk to skip
317 the most expensive phases of the function. [William Rowe]
319 *) Allow ApacheMonitor to connect to and control Apache on other
320 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
322 *) Remove the Port directive. In it's place, the Listen directive
323 is now a required directive, which tells Apache what port to
324 listen on. The ServerName directive has also been extended
325 to accept an optional port. If the port is specified to the
326 ServerName, the server will report that port whenever it
327 reports the port that it is listening on. This change was
328 made to ease configuration errors that stem from having a Port
329 directive, and a Listen directive. In that situation, the server
330 would only listen to the port specified by the Listen command,
331 which caused a lot of confusion to users. [Ryan Bloom]
333 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
334 build, as loadable modules. [William Rowe]
336 *) Fix --enable-mods-shared processing. If most is specified,
337 then all modules that can be compiled as shared modules are.
338 [Aaron Bannert <aaron@clove.org>]
340 *) Update the mime.types file to map video/vnd.mpegurl to mxu
341 and add commonly used audio/x-mpegurl for m3u extensions.
342 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
344 *) Eliminate the depreciated r->content_language, in favor of the array
345 r->content_languages introduced many years ago. Module authors must
346 substantially overhaul their modules, so this needs to be upgraded
347 if the module still relied on backwards-brokeness. [William Rowe]
349 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
352 *) Rewrite the input filtering mechanisms to consolidate and reorganize
353 code. In short, core_input_filter does something now and
354 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
356 *) Update the Win32 build to re-absorb mod_proxy and family.
359 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
360 current SDK.) [William Rowe]
362 *) Some style changes to the code that does ProxyErrorOverride. Fixed
363 config merge behaviour. [Graham Leggett]
365 *) Allow support programs to be compiled against a static version
366 of libapr. This allows the smaller support programs to be
367 relocated. [Aaron Bannert <aaron@clove.org>]
369 *) Update the mime.types file to the registered media types as
370 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
372 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
373 number of clients that can connect at the same time, instead of
374 specifying the maximum number of child processes.
375 [Aaron Bannert <aaron@clove.org>]
377 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
378 be consistent with 1.3. [Justin Erenkrantz]
380 *) Cache apr_explode_localtime() value for 15 seconds.
381 [Brian Pane <bpane@pacbell.net>]
383 *) Fix mod_include to not return ETag or Last-Modified headers.
384 [Ian Holsman <ianh@cnet.com>]
386 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
388 *) Eliminate the wasteful run-time conversion of method names from strings
389 to numbers in places where the methods are known at compile time.
390 [Brian Pane <bpane@pacbell.net>]
392 *) Turn the worker MPM's queue into a LIFO. This may
393 improve cache-hit performance under some conditions.
394 [Aaron Bannert <aaron@clove.org>]
396 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
397 support it. [Justin Erenkrantz]
399 *) Cleanup the worker MPM. We no longer re-use transaction
400 pools. This incurs less overhead than shuffling the pools
401 around so that they can be re-used. Remove one of the
402 queue's condition variables. We just redefined the API to
403 state that you can't try to add more stuff than you allocated
404 segments for. [Aaron Bannert <aaron@clove.org>]
406 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
408 *) Fixed persistent connections when a request contains a body.
411 *) mod_dav uses a new API to speak to the backend provider for dead
412 property management. [Greg Stein]
414 *) Remove the Win32 script-processing exception from mod_cgi, and
415 roll build_command_line/build_argv_list into a unified, overrideable
416 ap_cgi_build_command optional function. [William Rowe]
418 *) Rewrite find_start_sequence to use a better search algorithm
419 to find the start tag. [Justin Erenkrantz]
421 *) Fix a seg fault in mod_include. When we are generating an
422 internal redirect, we must set r->uri to "", not a bogus
423 string, and not NULL. [Ryan Bloom]
425 *) Optimized location_walk, so subrequests, redirects and second passes
426 now reuse previous section merges on a <Location > by <Location >
427 basis, until we mismatch with the original location_walk.
430 *) Back out the 1.45 change to util_script.c. This change made
431 us set the environment variable REQUEST_URI to the redirected
432 URI, instead of the originally requested URI.
433 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
435 *) Make mod_include do lazy evaluation of potentially expensive to
436 compute variables. [Brian Pane <bpane@pacbell.net>]
438 *) Fix logging of bytes sent for HEAD requests. %b and %B should
439 log either - or 0, before this patch, they were both logging
440 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
442 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
443 than per character. [Brian Pane <bpane@pacbell.net>]
445 *) Normalize the primary request, redirects and sub-requests to
446 run the same ap_process_request_internal for consistency in
447 robustness, behavior and security. [William Rowe]
449 *) Fix a segfault with mod_include when r->path_info is not set
450 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
452 *) Add -X functionality back. This indicates to all MPMs and any other
453 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
455 *) Some initial support for the cygwin platform [prefork only].
456 This is not to be confused with support for the WinNT/Win32
457 platform, which is the recommended configuration for native
458 Win32 users. The cygwin platform support is recommended for
459 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
461 *) Changed syntax of Set{Input|Output}Filter. The list of filters
462 must be semicolon delimited (if more than one filter is given.)
463 The Set{Input|Output}Filter directive now overrides a parent
464 container's directive (e.g. SetInputFilter in <Directory /web/foo>
465 will override any SetInputFilter directive in <Directory /web>.)
466 This new syntax is more consistent with Add{Input|Output}Filter
467 directives defined in mod_mime. Also cures a bug in prior releases
468 where the Set{Input|Output}Filter directive would corrupt the
469 global configuration if the multiple directives were nested.
472 *) Cured what's ailed mime for quite some time. If an AddSomething
473 was given in the configuration (Language, Charset, Handler or
474 Encoding) Apache would set the content type as given by AddType,
475 but refused to check the mime.types file if AddType wasn't given
476 for that specific extension. Setting the AddHandler for .html
477 without setting the AddType text/html html would cause Apache to
478 use the default content type. [William Rowe]
480 *) Added some bulletproofing to memory allocation in the LDAP cache
481 code. [Graham Leggett]
483 Changes with Apache 2.0.25
485 *) Move the installed /manual directory out of the /htdocs/ tree, so
486 that it can be kept more independently from the remaining document
487 root. The "Alias /manual ..." already allowed for easy projection
488 into existing private document trees. [Martin Kraemer]
490 *) Add specified user attributes to the environment when using
491 mod_auth_ldap. This allows you to use mod_include to embed specified
492 user attributes in a page like so:
493 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
496 *) Fix a performance problem with the worker MPM. We now create
497 transaction pools once, and re-use them for each connection.
498 [Aaron Bannert <aaron@clove.org>]
500 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
501 of a 'handler' or 'filter', so that any filename extension that does
502 not contribute to the negotiated metadata can't be served without
503 an explicit request. E.g., if the .Z extension is associated with
504 an unzip filter, the user request somefile.Z.html, mod_negotiation
505 won't serve it. It can serve somefile.Z.html when somefile.Z is
506 requested, since the .Z extension is explictly requested, if the
507 .html extension is associated with ContentType text/html.
510 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
511 and corresponding AddOutputFilter syntax, to insert one or more
512 filters by mod_mime filename extension processing.
515 *) Fix a growing connection pool in core_output_filter() for
516 keepalive requests. [Jeff Trawick]
518 *) Moved split_and_pass_pretag_buckets back to being a
519 macro at Ryans's request. Removed the return from it
520 by setting and returning a return code instead. Updated
521 the code to check the return code from the macro and
522 do the right thing. [Paul J. Reder]
524 *) Fix a segfault when a numeric value was received for Host:.
527 *) Add a function ap_remove_input_filter. This is to match
528 up with ap_remove_output_filter. [Ryan Bloom]
530 *) Clean up location_walk, so that this step performs a minimum
531 amount of redundant effort (it must be run twice, but it will no
532 longer reparse all <Location > blocks when the request uri
533 hadn't changed.) [William Rowe]
535 *) Eliminate proxy: (and all other 'special') processing from the
536 ap_directory_walk() phase. Modules that want to use special
537 walk logic should refer to the mod_proxy map_to_location example,
538 with it's proxy_walk and proxysection implementation. This makes
539 either directory_walk flavor much more legible, since that phase
540 only runs against real <Directory > blocks.
543 *) Fix a security problem in mod_include which would allow
544 an SSI document to be passed to the client unparsed.
545 [Cliff Woolley, Brian Pane]
547 *) Introduce the map_to_storage hook, which allows modules to bypass
548 the directory_walk and file_walk for non-file requests. TRACE
549 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
550 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
553 *) Add the ability for mod_include to add the INCLUDES filter
554 if the file is configured for the server-parsed handler.
555 This makes the configuration for .shtml files much easier
556 to understand, and allows mod_include to honor Apache 1.3
557 config files. Based on Doug MacEachern's patch to PHP
558 to do the same thing. [Ryan Bloom]
560 *) force OpenSSL to ignore process local-caching and to always
561 get/set/delete sessions using mod_ssl's callbacks
562 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
563 Geoff Thorpe <geoff@geoffthorpe.net>]
565 *) Make the worker MPM shutdown and restart cleanly. This also
566 cleans up some race conditions, and gets the worker using
567 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
569 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
571 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
573 *) Fix for mod_include. Ryan's patch to check error
574 codes put a return in the wrong place. Also, the
575 include handler return code wasn't being checked.
576 I don't like macros with returns, so I converted
577 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
578 [Paul J. Reder <rederpj@raleigh.ibm.com>]
580 *) fix segv in mod_mime if no AddTypes are configured
581 [John Sterling <sterling@covalent.net>]
583 *) Enable ssl client authentication at SSL_accept time
584 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
586 *) Fix a segfault in mod_include when the original request has no
587 associated filename (e.g., we're filtering the error document for
588 a bad URI). [Jeff Trawick]
590 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
592 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
593 of httpd is started and shuts down due to socket conflict. Moving the
594 call to ap_log_pid solves the problem.
596 *) Changed the late-1.3 log_config substitution %c to %X, to log the
597 status of the closed connection, as it conflicts with the far more
598 common, historical ssl logging directive %...{var}c. [William Rowe]
600 *) Added the common error/ tree to the build/install targets
601 (similar to the common icons/ tree) for the multi-language error
602 messages that Lars committed earlier. [William Rowe]
604 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
606 *) Added a default commented-out mod_ldap and mod_auth_ldap
607 configuration to httpd-std.conf and httpd-win.conf
610 *) Added documentation for mod_ldap and mod_auth_ldap.
613 *) Enabled negative caching on attribute comparisons in the LDAP cache.
614 Fixed a problem where the default cache TTL was set in milliseconds
615 not microseconds causing the cache to time out almost immediately.
618 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
619 module code to follow APR. [Graham Leggett]
621 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
622 cleaned up when the connection pool pool is cleaned up.
625 *) Fix a minor issue with Jeff Trawick's mod_include
626 patch. Without this patch, the code will just allocate
627 more bytes in get_combined_directive than are needed.
630 *) Added the LDAP authentication module mod_auth_ldap.
631 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
633 *) Added the LDAP cache and connection pooling module mod_ldap.
634 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
636 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
637 by allowing a module to disable itself if its prerequisites are not
638 met. [Justin Erenkrantz]
640 Changes with Apache 2.0.24
642 *) Fix a couple of issues in mod_include when the tag appeared at
643 offsets near 8192 in the file being parsed. [Jeff Trawick]
645 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
646 reached. [Jeff Trawick]
648 *) Numerous improvements to the Win32 build system. Introduced command line
649 builds without requiring .mak files for MSVC 6.0 and later versions.
650 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
653 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
654 reporting of uninstalled services and other error conditions, and changed the
655 default service name to Apache2. [William Rowe]
657 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
658 compatibility with existing Apache 1.3 Win32 Apache management utilites.
659 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
661 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
662 [William Rowe, Greg Ames]
664 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
665 and RemoveCharset directives. [William Rowe]
667 *) The Unix MPMs other than perchild now allow child server
668 processes to use the accept mutex when starting as root and
669 using SysV sems for the accept mutex. Previously, this
670 combination would lead to fatal errors in the child server
671 processes. perchild can't use SysV sems because of security
672 issues. [Jeff Trawick, Greg Ames]
674 *) Added Win32 revision stamp resources to all http binaries
675 (including modules/ and support/ tools.) PR7322 [William Rowe]
677 *) Fix ap_rvprintf to support more than 4K of data at one time.
678 [Cody Sherr <csherr@covalent.net>]
680 *) We have always used the obsolete/deprecated Netscape syntax
681 for our tracking cookies; now the CookieStyle directive
682 allows the Webmaster to choose the Netscape, RFC2109, or
683 RFC2965 format. The new CookieDomain directive allows the
684 setting of the cookie's Domain= attribute, too. PR #s 5006,
685 5023, 5920, 6140 [Ken Coar]
687 *) Tweak server/Makefile so that the rules for generating exports.c
688 are compatible with make utilities which don't expand wildcards
689 in a dependency list (e.g., OS/390 make, certain levels of GNU
690 make). [Jeff Trawick]
692 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
694 *) Begin to sanitize the MPM configuration directives. Now, all
695 MPMs use the same functions for all common MPM directives. This
696 should make it easier to catch all bugs in these directives once.
697 [Cody Sherr <csherr@covalent.net>]
699 *) Close a major resource leak. Every time we had issued a
700 graceful restart, we leaked a socket descriptor.
703 *) Fix a problem with the new method code. We need to cast
704 the 1 to an apr_int64_t or it will be treated as a 32-bit
705 integer, and it will wrap after being shifted 32 times.
706 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
708 *) Fix a bug in mod_expires. Previous to this patch, if you
709 told mod_expires to add 604800 seconds to the last-modified
710 time, it actually added 604800 usec's to the last-modified time,
711 so that when looking at the response it looked like nothing
712 had been done. The root of the problem was that we always compute
713 time in usec's, but we ask users to input sec's. This means we
714 need to convert to usec's before using those values.
717 *) The worker MPM now handles shutdown and restart requests. It
718 definitely isn't perfect, but we do stop the servers correctly.
719 The biggest problem right now is that SIGHUP causes the server to
720 just die. [Ryan Bloom]
722 Changes with Apache 2.0.23
724 *) Use the prefork MPM by default on Unix. [various]
726 *) Added a systray icon monitor application for Win32.
727 [Mladen Turk <mturk@mappingsoft.com>]
729 *) mod_rewrite: Fix the line ending on some non-Unix systems for
730 messages written to the rewrite log.
731 [Richard Labennett <rlabenn@us.ibm.com>]
733 *) All mod_autoindex query parsing is now quietly quashed with the
734 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
735 still drops the column sort <a href>'s for the column headers, but
736 IgnoreClient is required to ignore these Query options entirely.
739 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
740 to allow the client to select plain, FancyIndexing or HTMLTable
741 formatting, V=[0|1] to inhibit or enable version sorting, and
742 P=pattern to return only specific files. The old Query Arguments
743 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
744 as before), and O=A|D for ordering ascending or descending.
747 *) Fixed an error in mod_include's directive parsing routines which
748 caused #if, #elif, and #else expressions containing backslashes
749 to be improperly evaluated. [Cliff Woolley]
751 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
752 drop the icon column, SuppressRules to drop the <hr> elements,
753 and HTMLTable to create rudimentary HTML table listings (implies
754 FancyIndexing). [William Rowe]
756 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
757 from Apache 1.3.15. This is needed for two reasons, first, given
758 multiple machines within a server farm, ETags and Last-Modified
759 stamps won't correspond from machine to machine, and second, many
760 Unixes don't capture changes to the date or time stamp of existing
761 files, since these don't modify the dirent itself. [William Rowe]
763 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
764 and DirectoryWidth options from Apache 1.3.10.
765 [William Rowe, Ken Coar]
767 *) Eliminated FancyIndexing directive, deprecated early in Apache
768 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
770 *) mod_autoindex now excludes any file names that would result in
771 an error, other than a success or redirect. Also optimized
772 the parent directory, always included except in the URI '/'.
775 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
776 negotiated index pages, and prevent the server from defaulting
777 to an autoindex of the directory. mod_negotiation will now die
778 with a 500 Internal Error if it could match some filenames
779 (e.g. for mod_dir) but none can be served. mod_negotation now
780 refuses to serve any file with an extention that mod_mime doesn't
781 recognize, and wasn't part of the request. [William Rowe]
783 *) Eliminate mod_cgi's handling of .exe files without the .exe file
784 extension. This is already handled by multiviews, if the admin
785 wishes to AddHandler .exe or define a content type handler and
786 associate .exe files with that content type. Multiviews must be
787 enabled to allow these to be served. [William Rowe]
789 *) Speed up the server's response to a spike in incoming workload
790 or restarts by assigning empty scoreboard slots to new processes
791 when they are available. [Greg Ames]
793 *) Add a handler to mod_includes.c. This handler is designed to
794 implement the XbitHack directive. This can't be done with a
795 fixup, because we need to check the content-type, which is
796 only available in the handler phase. [Ryan Bloom]
798 *) Make the includes filter check return codes from filters lower in
799 the filter chain. If a lower level filter returns an error, then
800 the request needs to stop immediately. This allows mod_include to
801 stop parsing data once a lower filter recognizes an error.
804 *) Add the ability to extend the methods that Apache understands
805 and have those methods <limit>able in the httpd.conf. It uses
806 the same bit mask/shifted offset as the original HTTP methods
807 such as M_GET or M_POST, but expands the total bits from an int to
808 an ap_int64_t to handle more bits for new request methods than
809 an int provides. [Cody Sherr <csherr@covalent.net>]
811 *) Fix broken mod_mime behavior in merging its arguments. Possible
812 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
814 *) Solve many mod_ssl porting issues (too many to detail) with
815 help from the whole team, but most notably [Ralf S. Engelschall,
816 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
817 Doug MacEachern, William Rowe, Cliff Woolley]
819 *) More stall fixes for the threaded & worker mpm's.
820 Make mod_status output more accurate. Don't
821 count workers in processes which aren't actively
822 serving requests. [Greg Ames]
824 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
826 *) Add a single listener/multiple worker MPM. This MPM is
827 definately not fully correct, but it allows us to solve many
828 of the problems that exist in the threaded MPM. This is a
829 modified version of the threaded MPM. [Ryan Bloom]
831 *) Improve content generation throughout Apache, providing closer
832 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
833 Transitional specifications. [William Rowe]
835 Changes with Apache 2.0.22
837 *) Fix a problem where the threaded MPM stalls after restarts or
838 segfaults. Also prevent multiple active processes from using
839 the same scoreboard slot. [Greg Ames]
841 *) Apache/Win32 now fills in the service description with Apache's
842 server version string, including loaded and advertised modules.
845 *) Improved support for the Win32 build, to recover gracefully from
846 missing apr or apr-util directories or the awk interpreter,
847 create the proper cgi-bin examples, including a test-cgi.bat, and
848 fix the perl shebang line for printenv.pl, when installing from
849 the build environment. [William Rowe]
851 *) Fix a segfault in threaded.c caused by passing uninitialized
852 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
854 *) Use new APR number conversion functions to reduce CPU consumption
855 when setting the content length, and in mod_log_config.
858 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
859 where HEAD response headers were being repeated twice for
860 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
861 problem in the http_header filter was exposed by the recent rewrite
862 of the content_length filter. [Taketo Kabe, Bill Stoddard]
864 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
865 restarts. A garbage pointer to a vhost's server_rec from the
866 previous generation was being left around under certain
867 conditions. [Greg Ames]
869 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
870 used to appear as '(none', without the closing paren.
871 [Günter Knauf <eflash@gmx.net>]
873 *) Improve the exports generating awk script. In the past, we had
874 work around problems in the awk script by avoiding some #if and
875 #ifdefs. This has bitten us many times in generating the exports.c
876 file. This improvement allows corrects the header file parsing.
877 [Sander Striker <striker@apache.org>]
879 Changes with Apache 2.0.21
881 *) Resolve the Win32 htpasswd bug, where a file that existed would be
882 overwritten, regardless of the -c flag.
883 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
885 *) Introduce connection sub-pools into ab. Truncating the lifetime
886 of these allocations means that ab no longer perpetually grows
887 its working set, running out of memory on large request attempts.
890 *) Make scoreboard creation a hook. This allows management
891 modules to have access to the scoreboard at the time that it is
892 created, and at every restart request.
893 [Cody Sherr <csherr@covalent.net>]
895 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
896 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
897 daemon index actually used in the scoreboard. I also
898 updated the pertinent calls. [Paul J. Reder]
900 *) Win32: Prevent listening sockets from being inherited by
901 the Apache child process, CGI scripts, rotatelog process
902 etc. If the Apache child process segfaults, any processes
903 that the child started are not reaped. Prior to this fix,
904 these processes inherited the listening sockets which sometimes
905 prevented the restarted Apache child process from accepting
906 connections (ie, the server would hang).
909 *) Provide vhost and request strings when ExtendedStatus is on.
912 *) Fix some issues with the pod and prefork: check the pod *after*
913 processing a connection so that a server processing a time-
914 consuming request bails out as soon as practical; when the
915 parent process wakes up a server process via connect(), use an
916 APR timeout on the connect() so that we don't hang for a long
917 time if there aren't server processes around to do accept().
918 [Jeff Trawick, Greg Ames]
920 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
921 spends a lot of time in apr_table_get calls. Using the default
922 httpd.conf, the tables for languages and charsets are somewhat
923 large, so the time spent scanning them on each request is
924 significant. Replacing the tables with hash tables provides
925 a nice speedup. [Brian Pane <bpane@pacbell.net>]
927 *) Add two functions to allow modules to access random parts of the
928 scoreboard. This allows modules compiled for one MPM to access the
929 scoreboard, even if it the server was compiled for another MPM.
930 [Harrie Hazewinkel <harrie@covalent.net>]
932 Changes with Apache 2.0.20
934 *) Fix problem in content-length filter where the filter would
935 buffer all the output from a CGI before sending any bytes
936 down the filter stack to the network. This problem would cause
937 significant memory consumption if the CGIs generated
938 lots of bytes. [Bill Stoddard]
940 *) Get non-blocking CGI pipe reads working with the bucket brigades.
943 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
946 *) Fix a bug in the threaded MPM that would cause it to kill off all
947 workers immediately after starting if the number of workers started
948 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
950 Changes with Apache 2.0.19
952 *) Fix problem with threaded MPM. The problem was that if each child
953 process was busy serving a single long-lived request and the server
954 was sent a graceful restart signal, the server would stop serving
955 requests. This would happen because each child process would wait to
956 die until the last thread was done, and the parent wouldn't spawn any
957 new children until a process died. Now, the parent looks at the fact
958 that the children are dying gracefully, and starts new children.
959 Those new children only start enough threads to compliment the number
960 of threads in the other child process that shares the same spot in
961 the scoreboard. In this way, we make sure to never go over
962 MaxClients. [Ryan Bloom]
964 *) modified mod_negotiation and mod_autoindex to speed up by almost a
965 factor of two on apr_dir_read()-enhanced platforms, such as Win32
966 and OS2, by calling ap_sub_request_lookup_dirent() with the results
967 already provided by apr_dir_read(). [William Rowe]
969 *) mod_file_cache is now more robust to filtering and serves requests
970 slightly more efficiently. [Cliff Woolley]
972 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
973 Module was calling ap_rwrite() followed by ap_rflush() but the
974 served content was not being displayed in the browser. Inspection
975 of the output stream revealed that the first data chunk was
976 missing the trailing CRLF required by the RFC. [Bill Stoddard]
978 *) apxs no longer generates ap_send_http_header() in the example handler
980 *) Fix an ab problem which could cause a divide-by-zero exception
981 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
982 [Ian Holsman <ianh@cnet.com>]
984 *) Solve case-insensitive platforms' confusion about negotiated
985 filenames, allowing files of differnt case to match in choosing
986 the document to serve. [William Rowe]
988 *) Fix brokenness when ThreadsPerChild is higher than the built-in
989 limit. We left ap_threads_per_child at the higher value which
990 led to segfaults when doing certain scoreboard operations.
993 *) Fix seg faults and/or missing output from mod_include. The
994 default_handler was using the subrequest pool for files and
995 MMAPs, even though the associated APR structures typically
996 live longer than the subrequest. [Greg Ames]
998 *) Extend mod_setenvif to support specifying regular expressions
999 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
1000 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
1001 will cause HAVE_TS to be set if any of the request headers begins
1002 with "TS" and has a value that begins with any character in the
1003 set [a-z]. [Bill Stoddard]
1005 *) httpd children now re-bind themselves to a random CPU on
1006 multiprocessor systems on AIX via bindprocessor() in 2.0.
1007 [Victor J. Orlikowski]
1009 *) Fix htdigest. It would go into a loop in getline when adding
1010 a second user. [Bill Stoddard]
1012 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
1014 *) Automatically generate httpd.exp for AIX.
1015 DSOs now work again on AIX in 2.0
1016 [Victor J. Orlikowski]
1018 *) Add a new request hook, error_log. This phase allows modules
1019 to act on the error log string _after_ it has been written
1020 to the error log. The goal for this hook is to allow monitoring
1021 modules to send the error string to the monitoring agent.
1024 *) Modify mod_echo to make it use filters for input and output.
1025 [Ryan Morgan <rmorgan@covalent.net>]
1027 *) Extend mod_headers to support conditional driven Header
1028 add, append and set. Use SetEnvIf to set an envar and conditionally
1029 add/append/set headers based on this envar thusly:
1031 SetEnvIf TSMyHeader value HAVE_TSMyHeader
1032 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
1034 If the request contains header "TSMyHeader: value" then header
1035 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
1038 *) Extend mod_headers to support using format specifiers on Header
1039 add, append and set header values. Two format specifiers are supported:
1041 %t - reports, in UTC microseconds since the epoch, when the
1042 request was received.
1044 %D - reports the time, in microseconds, between when the request was
1045 received and the response sent.
1048 Header add MyHeader "This request served in %D microseconds. %t"
1050 results in a header being added to the response that looks like this:
1052 MyHeader: This request served in D=5438 microseconds. t=991424704447256
1056 *) Fix reset_filter(). We need to be careful how we remove filters.
1057 If we set r->output_filters to NULL, we also have to reset the
1058 connection's filters. [John Sterling]
1060 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
1062 *) Add a check to ap_die() to make sure the filter stack is sane and
1063 contains the correct basic filters when an error occurs. This fixes
1064 a problem where headers are not being sent on error. [John Sterling]
1066 *) New Header directive 'echo' option. "Header echo regex" will
1067 cause any headers received on the request that match regex to be
1068 echoed to (included in) the response headers.
1071 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
1072 This prevented the inclusion of apr_compat.h. PR #7773
1073 [Oleg Broytmann <phd@phd.pp.ru>]
1075 *) Moved util_uri to the apr-util library. This required a bunch of
1076 apr_name changes for the uri utility functions. [Justin Erenkrantz]
1078 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
1079 insert_filter phase so that other filters are not bypassed by default.
1082 *) Reimplement mod_headers as an output filter. mod_headers can now
1083 add custom headers to inbound requests using the RequestHeader directive
1084 and to responses using the same old Header directive. [Graham Leggett]
1086 Changes with Apache 2.0.18
1088 *) Fix command-line processing so that if a bad argument is specified
1089 Apache will exit. [Jeff Trawick]
1091 *) Change the make targets and rules to be consistent in all of the
1092 Apache-owned source trees. [Roy Fielding]
1094 *) Fix processing of the TRACE method. Previously we passed bogus
1095 parms to form_header_field() and it overlaid some vhost structures,
1096 resulting in a segfault in check_hostalias().
1097 [Greg Ames, Jeff Trawick]
1099 *) Win32: Add support for reliable piped logs. If the logging process
1100 goes down, Apache will automatically restart it. This function has
1101 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
1104 *) Do not start piped log processes during the config file
1105 preflight. This change also circumvents a problem on
1106 Windows where the rotatelog processes created during preflight
1107 was not getting cleaned up properly.
1110 *) add "Request Phase Participation" info to mod_info
1113 *) Make first phase changes to the scoreboard data structures in
1114 preparation for the rewriting of the scoreboard per my posted
1115 design notes. [Paul J. Reder]
1117 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
1118 and apr-util, allow it to be overridden by the configure command-line
1119 (default="--silent") and introduce LT_LDFLAGS to replace what we were
1120 formerly abusing as LTFLAGS. [Roy Fielding]
1122 *) Clean up the reporting of incorrect closing container tags.
1123 [Barrie Slaymaker <barries@slaysys.com>]
1125 *) Simplify the configure process by moving all libtool stuff to APR
1126 and moving hints.m4 inline. [Roy Fielding]
1128 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
1129 of functions used by mod_proxy for export in the DLL
1130 [Ian Holsman <IanH@cnet.com>]
1132 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
1133 request body from its stdin but no reqest body is being written to
1134 the cgi. [Jeff Trawick]
1136 *) mod_log_config: %c connection status incorrectly logged
1137 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
1140 *) Get mod_cern_meta working under Windows
1143 *) Create Files, and thus MMAPs, out of the request pool, not the
1144 connection pool. This solves a small resource leak that had us
1145 not closing files until a connection was closed. In order to do
1146 this, at the end of the core_output_filter, we loop through the
1147 brigade and convert any data we have into a single HEAP bucket
1148 that we know will survive clearing the request_rec.
1149 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
1152 *) Completely revamp configure so that it preserves the standard make
1153 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
1154 the configure additions to EXTRA_* variables. Also, allow the user
1155 to specify NOTEST_* values for all of the above, which eliminates the
1156 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
1157 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1158 avoid pointless duplications. Fix the order in which flags are given
1159 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1160 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1161 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1162 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1164 *) Get mod_tls to compile/work better on Windows. PR #7612
1165 [Bernhard Schrenk <b.schrenk@improx.com>]
1167 *) Fix shutdown/restart hangs in the threaded MPM.
1168 [Jeff Trawick, Greg Ames, Ryan Bloom]
1170 *) Removed the keptalive boolean from conn_rec because it is now only
1171 used by a single routine and can be replaced by a local variable.
1172 [Greg Stein, Ryan Bloom, Roy Fielding]
1174 *) Patch prefork to put enough of the signal processing back in so that
1175 signals are all handled properly now. The previous patch fixed the
1176 deadlock race condition, but broke the user directed signal handling.
1177 This fixes it to work the way it did before my previous prefork patch
1178 (primarily, SIGTERM is now working).
1180 *) Change how input filters decide how much data is returned to the
1181 higher filter. We used to use a field in the conn_rec, with this
1182 change, we use an argument to ap_get_brigade to determine how much
1183 data is retrieved. [Ryan Bloom]
1185 *) Fix seg fault at start-up introduced by Ryan's change to enable
1186 modules to specify their own logging tags. mod_log_config
1187 registers an optional function, ap_register_log_handler().
1188 ap_register_log_handler() was being called by http_core before
1189 the directive hash table was created. This patch creates the
1190 directive hash table before ap_register_log_handler() is
1191 registered as an optional function.
1192 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1194 *) Add ap_set_int_slot() function
1195 [John K. Sterling <sterling@covalent.net>]
1197 *) Under certain circumstances, Apache did not supply the
1198 right response headers when requiring authentication.
1199 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1200 (This is a port of the change that went into Apache 1.3.19.)
1202 *) Allow modules to specify their own logging tags. This basically
1203 allows a module to tell mod_log_config that when %x is encountered
1204 a specific function should be called. Currently, x can be any single
1205 character. It may be more useful to make this a string at some point.
1208 Changes with Apache 2.0.17
1210 *) If a higher-level filter handles the the byterange aspects of a
1211 request, then the byterange filter should not try to redo the
1212 work. The most common case of this happening, is a byterange
1213 request going through the proxy, and the origin server handles
1214 the byterange request. The proxy should ignore it.
1215 [Graham Leggett <minfrin@sharp.fm>]
1217 *) Changed the threaded mpm to have child_main join to each of the
1218 worker threads to make sure the kids are all gone before child_main
1219 exits after a signal (cleanup from perform_idle_server_maintenance).
1220 This is an extension of Ryans recent commit to make the child_main
1223 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1224 report if their threads are dynamic or static. Finally, this also
1225 implements a new API, ap_show_mpm, which returns the MPM that was
1226 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1228 *) Do not install the binaries from the support directory twice.
1229 [jun-ichiro hagino <itojun@iijlab.net>]
1231 *) The ap_f* functions should flush data to the filter that is passed
1232 in, not the the filter after the one passed in.
1233 [Ryan Morgan <rmorgan@covalent.net>]
1235 *) Make ab work again by changing its native types to apr types and formats.
1236 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1238 *) Move the byterange filter and all of the supporting functions back
1239 to the HTTP module. The byterange filter turned out to be very
1240 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1242 *) Make clean, distclean, and extraclean consistently according to the
1243 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1245 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1246 This may have been causing problems stopping processes in the threaded
1249 *) Fix content-length in mod_negotiation to a long int representation.
1252 *) Remove BindAddress from the default config file.
1253 [giles@nemeton.com.au]
1255 *) Allow module authors to add a module to their Apache build using
1256 --with-module, without re-running buildconf. The syntax is:
1257 --with-module=module_type:/path/to/module.c
1258 The configure script will copy the module.c file to
1259 modules/module_type, and it will be added to the relevant Makefiles.
1260 currently, this only works for static modules. [Ryan Bloom]
1262 *) Changes required to make prefork clean up idle children properly.
1263 There was a window during which a starting worker deadlocks when
1264 an idle cleanup arrives before it completes init. Apache then keeps
1265 trying to cleanup the same deadlocked worker forever (until higher
1266 pids come along, but it still will never reduce below the deadlocked
1267 pid). Thus the number of children would not reduce to the correct
1268 idle level. [Paul J. Reder]
1270 Changes with Apache 2.0.16
1272 *) Change the default installation directory to /usr/local/apache2,
1273 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1275 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1278 *) Get MaxRequestsPerChild working with the Windows MPM.
1281 *) Make generic hooks to work, with mod_generic_hook_import/export
1282 experimental modules. [Ben Laurie, Will Rowe]
1284 *) Fix segfaults for configuration file syntax errors such as
1285 "<Directory>" followed by "</Directory" and
1286 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1288 *) Cleanup the --enable-layout option of configure. This makes
1289 us use a consistent location for the config.layout file, and it
1290 makes configure more portable.
1291 [jun-ichiro hagino <itojun@iijlab.net>]
1293 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1294 csv/gnuplot format, rudimentary ssl support and various other tweaks
1295 to make results more true to what is measured. The upshot of this it
1296 turns out that 'ab' has often underreported the true performance of
1297 apache. Often by a order of magnitude :-) See talk/paper of Sander
1298 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1299 [Dirk-Willem van Gulik]
1301 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1302 storage leak this ensures that some unnecessary pipes are closed.
1305 *) Performance: Add quick_handler hook. This hook is called at the
1306 very beginning of the request processing before location_walk,
1307 translate_name, etc. This hook is useful for URI keyed content
1308 caches like Mike Abbott's Quick Shortcut Cache.
1311 *) top_module global variable renamed to ap_top_module [Perl]
1313 *) Move ap_set_last_modified to the core. This is a potentially
1314 controversial change, because this is kind of HTTP specific. However
1315 many protocols should be able to take advantage of this kind of
1316 information. I expect that headers will need one more layer of
1317 indirection for multi-protocol work, but this is a small step in
1318 the right direction. [Ryan Bloom]
1320 *) Enable mod_status by default. This matches what Apache 1.3 does.
1323 *) Add a ScriptSock directive to the default config file. This is
1324 only enabled when mod_cgid is used.
1325 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1327 Changes with Apache 2.0.15
1329 *) Untangled the buildconf script and eliminated the need for build's
1330 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1331 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1333 *) Win32: Don't accept more connections than we have worker threads
1337 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1338 to fork() new child processes.
1341 *) Fix a major security problem with double-reverse lookup checking.
1342 Previously, a client connecting over IPv4 would not be matched
1343 properly when the server had an IPv6 listening socket. PR #7407
1344 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1346 *) Change the way the beos MPM handles polling to allow it to stop and
1347 restart. Problem was the sockets being polled were being reset by
1348 the select call, so once it had accepted a connection it was no
1349 longer listening on the UDP socket we use for shutdown instructions.
1350 APR needs to be altered, patch on it's way. [David Reid]
1352 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1353 on error exit from ap_getline(). Some other code got upset because
1354 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1356 *) Handle ap_discard_request_body() being called more than once.
1357 [Greg Ames, Jeff Trawick]
1359 *) Get rid of an inadvertent close of file descriptor 2 in
1360 mod_mime_magic. [Greg Ames, Jeff Trawick]
1362 *) Add a hook, create_request. This hook allows modules to modify
1363 a request while it is being created. This hook is called for all
1364 request_rec's, main request, sub request, and internal redirect.
1365 When this hook is called, the the r->main, r->prev, r->next
1366 pointers have been set, so modules can determine what kind of
1367 request this is. [Ryan Bloom]
1369 *) Cleanup the build process a bit more. The Apache configure
1370 script no longer creates its own helper scripts, it just
1372 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1374 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1375 proxy requests. [Graham Leggett]
1377 *) Avoid using sscanf to determine the HTTP protocol number in
1378 the common case because sscanf is a performance hog. From
1379 Mike Abbot's Accelerating Apache patch number 6.
1380 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1382 *) Fix a security exposure in mod_access. Previously when IPv6
1383 listening sockets were used, allow/deny-from-IPv4-address rules
1384 were not evaluated properly (PR #7407). Also, add the ability to
1385 specify IPv6 address strings with optional prefix length on Allow
1386 and Deny. [Jeff Trawick]
1388 *) Enhance rotatelogs so that a UTC offset can be specified, and
1389 the logfile name can be formatted using strftime(3). (Brought
1390 forward from 1.3.) [Ken Coar]
1392 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1393 DuplicateHandle on an IOCompletionPort (a practice which
1394 MS "discourages"). The new model does not rely on associating
1395 the completion port with the listening sockets, thus the
1396 completion port can be completely managed within the child
1397 process. A dedicated thread accepts connections off the network,
1398 then calls PostQueuedCompletionStatus() to wake up worker
1399 threads blocked on the completion port.
1402 *) Bring forward the --suexec-umask option which allows the
1403 builder to preset the umask for suexec processes. [Ken Coar]
1405 *) Add a -V flag to suexec, which causes it to display the
1406 compile-time settings with which it was built. (Only
1407 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1409 *) Mod_include should always unset the content-length if the file is
1410 going to be passed through send_parsed_content. There is no to
1411 determine if the content will change before actually scanning the
1412 entire content. It is far safer to just remove the C-L as long
1413 as we are scanning it. [Ryan Bloom]
1415 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1416 request and not Proxy-Authenticate.
1417 [Graham Leggett <minfrin@sharp.fm>]
1419 Changes with Apache 2.0.14
1421 *) Fix content-length computation. We ONLY compute a content-length if
1422 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1423 or we already have all the data. [Ryan Bloom]
1425 *) Report unbounded containers in the config file. Previously, a typo
1426 in the </container> directive could result in the rest of the config
1427 file being silently ignored, with undesired defaults used.
1430 *) Make the old_write filter use the ap_f* functions for the buffering.
1433 *) Move more code from the http module into the core server. This
1434 is core code, basically the default handler, the default input
1435 and output filters, and all of the core configuration directives.
1436 All of this code is required in order for the server to work, with or
1437 without HTTP. The server is closer to working without the HTTP
1438 module, although there is still more to do. [Ryan Bloom]
1440 *) Fix a number of SGI compile warnings throughout the server. Fix some
1441 bad parameters to apr_bucket_read(). Fix a bad statement in
1442 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1443 consistently; we were mixing apr_time_t and time_t in invalid ways
1444 before. In load_file(), call apr_dso_error() instead of
1445 apr_strerror() so that we get a more specific string on some platforms.
1446 PR #6980 [Jeff Trawick]
1448 *) Allow modules to query the MPM about it's execution profile. This
1449 query API can and should be extended in the future, but for now,
1450 max_daemons, and threading or forking is a very good start.
1451 [Jon Travis <jtravis@covalent.net>]
1453 *) Modify mod_include to send blocks of data no larger than 9k.
1454 Without this, mod_include will wait until the whole file is parsed,
1455 or the first tag is found to send any data to the client.
1456 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1458 *) Fix mod_info, so that <Directory> and <Location> directives are
1459 not displayed twice when displaying the current configuration.
1460 [Ryan Morgan <rmorgan@covalent.net>]
1462 *) Add config directives to override DEFAULT_ERROR_MSG and
1463 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1464 [Dan Rench <drench@xnet.com>]
1466 *) Get mod_info building and loading on Win32. [William Rowe]
1468 *) Begin to move protocol independant functions out of mod_http. The goal
1469 is to have only functions that are HTTP specific in the http directory.
1472 Changes with Apache 2.0.13
1474 *) Don't assume that there will always be multiple calls to the byterange
1475 filter. It is possible that we will need to do byteranges with only
1476 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1478 *) Move the error_bucket definition from the http module to the
1479 core server. Every protocol will need this ability, not just
1482 Changes with Apache 2.0.12
1484 *) Modify mod_file_cache to save pre-formatted strings for
1485 content-length and last-modified headers for performance.
1486 [Mike Abbot <mja@trudge.engr.sgi.com>]
1488 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1489 [Jon Travis <jtravis@covalent.net>]
1491 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1492 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1494 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1495 without ever filling it out. This fixes PR 7271.
1496 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1497 Cliff Woolley <cliffwoolley@yahoo.com>]
1499 *) Add a couple of GCC attribute tags to printf style functions.
1500 [Jon Travis <jtravis@covalent.net>]
1502 *) Add the correct language tag for interoperation with the Taiwanese
1503 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1505 *) Migrate the perchild MPM to use the new apr signal child, and
1506 APR thread functions. [Ryan Bloom]
1508 *) Close one copy of the CGI's stdout before creating the new process.
1509 The CGI will still have stdout, because we have already dup'ed it.
1510 This keeps Apache from waiting forever to send the results of a CGI
1511 process that has forked a long-lived child process.
1512 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1514 *) Remove the rest of the pthreads functions from the threaded MPM.
1515 This requires the APR support for a signal thread that was just
1518 *) Make mod_dir use a fixup for sending a redirect to the browser.
1519 Before this, we were using a handler, which doesn't make much
1520 sense, because the handler wasn't generating any data, it would
1521 either return a redirect error code, or DECLINED. This fits the
1522 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1524 *) Make the threaded MPM use APR threads instead of pthreads.
1527 *) Get mod_tls to the point where it actually appears to work in all cases.
1530 *) implement --enable-modules and --enable-mods-shared for "all" and
1531 "most". [Greg Stein]
1533 *) Move the threaded MPM to use APR locks instead of pthread locks.
1536 *) Rename mpmt_pthread to threaded. This is more in line with the
1537 fact that mpmt_pthread shouldn't be using pthreads directly, and
1538 it is a smaller name that doesn't tie into anything.
1541 *) Rename the module structures so that the exported symbol matches
1542 the file name, and it is easier to automate the installation
1543 process (generating LoadModule directives from the module filenames).
1546 *) Remove the coalesce filter. With the ap_f* functions, this filter
1547 is no longer needed. [Ryan Bloom]
1549 Changes with Apache 2.0.11
1551 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1552 added feature of allowing a uid/gid per child process. If no
1553 uid/gid is specified, then Perchild behaves exactly like dexter.
1556 *) Get perchild building again. [Ryan Bloom]
1558 *) Don't disable threads just because we are using the prefork MPM.
1559 If somebody wants to compile without threads, they must now add
1560 --disable-threads to the configure command line. [Ryan Bloom]
1562 *) Begin to move the calls to update_child_status into common code, so
1563 that each individual MPM does not need to update the scoreboard itself.
1566 *) Allow mod_tls to compile under Unix boxes where openssl has been
1567 installed to the system include files.
1568 [Gomez Henri <new-httpd@slib.fr>]
1570 *) Cleanup the mod_tls configure process. This should remove any need
1571 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1572 configure doesn't check that yet. [Ryan Bloom]
1574 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1575 vital that you read modules/tls/README before attempting to build
1578 *) Fix a potential seg fault on all platforms. David Reid fixed this
1579 on BEOS, but the problem could happen anywhere, so we don't want
1580 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1582 *) Add new LogFormat directive, %D, to log time it takes to serve a
1583 request in microseconds. [Bill Stoddard]
1585 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1586 SetOutputFilter. This corresponds nicely with the other Set
1587 directives, which operate on containers while the Add* directives
1588 tend to work directly on extensions. [Ryan Bloom]
1590 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1591 functions for the buffering so that we don't need to compute
1592 the length of the headers before we actually create the header
1593 buffer. [Ryan Bloom]
1595 *) Allow filters to buffer data using the ap_f* functions. These have
1596 become macros that resolve directly to apr_brigade_*.
1599 *) Get the Unix MPM's to do a graceful restart again. If we are going
1600 to register a cleanup with ap_cleanup_scoreboard, then we have to
1601 kill the cleanup with the same function, and that function can't be
1602 static. [Ryan Bloom]
1604 *) Install all required header files. Without these, it was not
1605 possible to compile some modules outside of the server.
1608 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1609 forward from 1.3 to 2.0, we missed a single line, which broke regex
1610 aliases. [Ryan Bloom]
1612 *) We have a poor abstraction in the protocol. This is a temporary
1613 hack to fix the bug, but it will need to be fixed for real. If
1614 we find an error while sending out a custom error response, we back
1615 up to the first non-OK request and send the data. Then, when we send
1616 the EOS from finalize_request_protocol, we go to the last request,
1617 to ensure that we aren't sending an EOS to a request that has already
1618 received one. Because the data is sent on a different request than
1619 the EOS, the error text never gets sent down the filter stack. This
1620 fixes the problem by finding the last request, and sending the data
1621 with that request. [Ryan Bloom]
1623 *) Make the server status page show the correct restart time, and
1624 thus the proper uptime. [Ryan Bloom]
1626 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1627 should reduce the amount of duplicate code that is required to
1628 create CGI processes.
1629 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1631 *) ap_new_connection() closes the socket and returns NULL if a socket
1632 call fails. Usually this is due to a connection which has been
1633 reset. [Jeff Trawick]
1635 *) Move the Apache version information out of httpd.h and into release.h.
1636 This is in preparation for the first tag with the new tag and release
1637 system. [Ryan Bloom]
1639 *) Begin restructuring scoreboard code to enable adding back in
1640 the ability to use IPC other than shared memory.
1641 Get mod_status working on Windows again. [Bill Stoddard]
1643 *) Make mod_status work with 2.0. This will work for prefork,
1644 mpmt_pthread, and dexter. [Ryan Bloom]
1646 *) Correct a typo in httpd.conf.
1647 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1649 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1651 *) Get the correct IP address if ServerName isn't set and we can't
1652 find a fully-qualified domain name at startup.
1653 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1655 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1657 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1658 'extra' stat's for user/group since they should never occur, and now
1659 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1660 volumes. [William Rowe]
1662 *) Adopt apr features to simplify mod_includes. This changes the
1663 behavior of the USER_NAME variable, unknown uid's are now reported
1664 as USER_NAME="<unknown>" rather than the old user#000 result.
1665 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1667 *) Adopt apr features for simplifing mod_userdir, and accept the new
1668 Win32/OS2 exceptions without hiccuping. [William Rowe]
1670 *) Replace configure --with-optim option by using and saving the
1671 environment variable OPTIM instead. This is needed because configure
1672 options do not support multiple flags separated by spaces.
1675 *) Fix some byterange handling. If we get a byte range that looks like
1676 "-999999" where that is past the end of the file, we should return
1677 a PARTIAL CONTENT status code, and return the whole file as one big
1678 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1680 *) Make the error bucket a real meta-data bucket. This means that the
1681 bucket length is 0, and a read returns NULL data. If one of these
1682 buckets is passed down after the headers are sent, this data will
1683 just be ignored. [Greg Stein]
1685 *) The prefork MPM wasn't killing child processes correctly if a restart
1686 signal was received while the process was serving a request. The child
1687 process would become the equivalent of a second parent process. If
1688 we break out of the accept loop, then we need to do die after cleaning
1689 up after ourselves. [Ryan Bloom]
1691 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1692 restarts. [Ryan Bloom]
1694 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1695 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1696 performing very expensive owner, group and permission lookups
1697 and allows the server to function until these apr_finfo_t fields
1698 are implemented under Win32. [William Rowe]
1700 *) Support for typedsafe optional functions - that is functions exported by
1701 optional modules, which, therefore, may or may not be present, depending
1702 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1703 for sample code. [Ben Laurie]
1705 *) filters can now report an HTTP error to the server. This is done
1706 by sending a brigade where the first bucket is an error_bucket.
1707 This bucket is a simple bucket that stores an HTTP error and
1708 a string. Currently the string is not used, but it may be needed
1709 to output an error log. The http_header_filter will find this
1710 bucket, and output the error text, and then return
1711 AP_FILTER_ERROR, which informs the server that the error web page
1712 has already been sent. [Ryan Bloom]
1714 *) If we get an error, then we should remove all filters except for
1715 those critical to serving a web page. This fixes a bug, where
1716 error pages were going through the byterange filter, even though
1717 that made no sense. [Ryan Bloom]
1719 *) Relax the syntax checking of Host: headers in order to support
1720 iDNS. PR#6635 [Tony Finch]
1722 *) Cleanup the byterange filter to use the apr_brigade_partition
1723 and apr_bucket_copy functions. This removes a lot of very messy
1724 code, and hopefully makes this filter more stable.
1727 *) Remove AddModule and ClearModuleList directives. Both of these
1728 directives were used to ensure that modules could be enabled
1729 in the correct order. That requirement is now gone, because
1730 we use hooks to ensure that modules are in the correct order.
1733 *) When SuExec is specified, we need to add it to the list of
1734 targets to be built. If we don't, then any changes to the
1735 configuration won't affect SuExec, unless 'make suexec' is
1736 specifically run. [Ryan Bloom]
1738 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1739 the APR_XTHREAD argument to open a file for consumption by
1740 parallel threads on win32. [William Rowe]
1742 *) Correct a bug in determining when we follow symlinks. The code
1743 expected a stat -1 result, not an apr_status_t positive error.
1744 Also check if the APR_FINFO_USER fields are valid before we
1745 follow the link. [William Rowe]
1747 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1748 mpm_common.c. These functions are only valid on some platforms,
1749 so they should not be in the main-line code. [Ryan Bloom]
1751 *) Remove ap_chdir_file(). This function is not thread-safe,
1752 and nobody is currently using it. [Ryan Bloom]
1754 *) Do not try to run make depend if there are no .c files in the
1755 current directory, doing so makes `make depend` fail.
1758 *) Update highperformance.conf to work with either prefork or
1759 pthreads mpms. [Greg Ames]
1761 *) Stop checking to see if this is a pipelined request if we know
1762 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1763 This keeps us from making an extra read call when serving a 1.0
1764 request. [Ryan Bloom and Greg Stein]
1766 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1767 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1768 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1770 *) Fix the RFC number mentioned when complaining about a missing
1771 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1773 *) Fix an endless loop in ab which occurred when ab was posting
1774 and the server dropped the connection unexpectedly.
1777 *) Fix a segfault while handling request bodies in ap_http_filter().
1778 This problem has been seen with mod_dav usage as well as with
1779 requests where the body was just being discarded. [Jeff Trawick]
1781 *) Some adjustment on the handling and automatic setting (via
1782 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1783 add the capability to specify flags (NOTEST_CFLAGS and
1784 NOTEST_LDFLAGS) which are used to compile Apache, but
1785 not used during the configuration process. Useful for
1786 flags like "-Werror". [Jim Jagielski]
1788 *) Stop using environment variables to force debug mode or
1789 no detach. We now use the -D command line argument to
1790 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1791 [Greg Stein, Ryan Bloom]
1793 *) Change handlers to use hooks. [Ben Laurie]
1795 *) Stop returning copies of filenames from both apr_file_t and
1796 apr_dir_t. We pstrdup the filenames that we store in the
1797 actual structures, so we don't need to pstrdup the strings again.
1800 *) mod_cgi: Fix some problems where the wrong error value was being
1801 traced. [Jeff Trawick]
1803 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1806 *) Add generic hooks. [Ben Laurie]
1808 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1810 *) Fix a segfault caused by mod_ext_filter when the external filter
1811 program does not exist. [Jeff Trawick]
1813 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1814 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1815 was served through mod_charset_lite (or anything else that would
1816 create a transient bucket in this size range). ap_bucket_make_heap()
1817 silently failed (fixed), transient_setaside() discovered it, but
1818 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1820 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1821 is that some browsers send extra lines at the end of POST requests, and
1822 we don't want to delay sending data back to the user just because the
1823 browser isn't well behaved. [Ryan Bloom]
1825 *) Get SuEXEC working again. We can't send absolute paths to suExec
1826 because it refuses to execute those programs. SuEXEC also wasn't
1827 always recognizing configuration changes made using the autoconf
1830 *) Allow the buildconf process to find the config.m4 files in the correct
1831 order. Basically, we can now name config.m4 files as config\d\d.m4,
1832 and we will sort them correctly when inserting them into the build
1833 process. [Ryan Bloom]
1835 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1836 This also allows mod_cgid to use ap_os_create_priviledged_process,
1837 thus allowing for SuExec execution from mod_cgid. Currently, we do
1838 not support everything that standard SuExec supports, but at least
1839 it works minimally now. [Ryan Bloom]
1841 *) Allow SuExec to be configured from the ./configure command line.
1844 *) Update some of the docs in README and INSTALL to reflect some of
1845 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1847 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1848 need to call sendfile again. This gets us serving large files
1849 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1851 *) Get the support programs building cleanly again.
1852 [Cliff Woolley <cliffwoolley@yahoo.com>]
1854 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1855 current directory logic now backs up over bin/ to determine the
1856 server root from the Apache.exe path.
1858 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1859 loadable modules, dynamic libs are all named libfoo.dll, and the
1860 makefile.win populates the include, lib and libexec directories.
1862 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1863 Apache gets IPv6 listening sockets by default. Additionally, the
1864 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1865 numeric address strings (e.g., "Listen [fe80::1]:8080").
1868 *) Modify the install directory layout. Modules are now installed in
1869 modules/. Shared libraries should be installed in libraries/, but
1870 we don't have any of those on Unix yet. All install directories
1871 are modifyable at configure time. [Ryan Bloom]
1873 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1875 *) Get the functions in server/linked into the server, regardless of
1876 which modules linked into the server. This uses the same hack
1877 for Apache that we use for APR and apr-util to ensure all of the
1878 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1879 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1880 the scripts a bit easier.
1883 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1884 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1886 *) Get all of the auth modules to the point that they will install and
1887 be loadable into the server. Our new build/install mechanism expects
1888 that all modules will have a common name format. The auth modules
1889 didn't use that format, so we didn't install them properly.
1892 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1893 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1895 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1897 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1898 after the end of the response. [Ryan Bloom]
1900 *) Get byterange requests working with responses that do not have a
1901 content-length. Because of the way byterange requests work, we have to
1902 have all of the data before we can actually do the byterange, so we
1903 can compute the content-length in the byterange filter.
1906 *) Get exe CGI's working again on Windows.
1909 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1910 they keep track of whether or not their post config hook has been
1911 called before. Instead of a static variable (which is replaced when
1912 the DSO is loaded a second time), use userdata in the process pool.
1915 Changes with Apache 2.0a9
1917 *) Win32 now requires perl to complete the final install step for users
1918 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1919 and installs the conf, htdocs and htdocs/manual directories.
1922 *) Make mod_include use a hash table to associate directive tags with
1923 functions. This allows modules to implement their own SSI tags easily.
1924 The idea is simple enough, a module can insert it's own tag and function
1925 combination into a hash table provided by mod_include. While mod_include
1926 parses an SSI file, when it encounters a tag in the file, it does a
1927 hash lookup to find the function that implements that tag, and passes
1928 all of the relevant data to the function. That function is then
1929 responsible for processing the tag and handing the remaining data back
1930 to mod_include for further processing.
1931 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1933 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1934 fewer parameters: the local and remote socket addresses were removed
1935 from the parameter list because all required information is available
1936 via the APR socket. [Jeff Trawick]
1938 *) Distribution directory structure reorganized to reflect a
1939 normal source distribution with external install targets.
1942 *) The MPMs that need multiple segments of shared memory now create
1943 two apr_shmem_t variables, one for each shared memory allocation.
1944 the problem is that we can't determine how much memory will be required
1945 for shared memory allocations once we try to allocate more than one
1946 variable. The MM code automatically aligns the shared memory allocations,
1947 so we end up needing to pad the amount of shared memory we want based
1948 on how many variables will be allocated out of the shared memory segment.
1949 It is just easier to create a second apr_shmem_t variable, and two
1950 shmem memory blocks.
1953 *) Cleanup the export list a bit. This creates a single unified list of
1954 functions exported by APR. The export list is generated at configure
1955 time, and that list is then used to generate the exports.c file.
1956 Because of the way the export list is generated, we only export those
1957 functions that are valid on the platform we are building on.
1960 *) Enable logging the cookie with mod_log_config
1961 [Sander van Zoest <sander@covalent.net>]
1963 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1966 *) Added lib/aputil/ as a placeholder for utility functions which are not
1967 specific to the Apache HTTP Server (but do not make sense with APR).
1968 The first utility is "apu_dbm": a set of functions to work with DBM
1969 files. This first version can be compiled for SDBM or GDBM databases.
1972 *) Complete re-write of mod_include. This makes mod_include a filter that
1973 uses buckets directly. This has now served the FAQ correctly.
1974 [Paul Reder <rederpj@raleigh.ibm.com>]
1976 *) Allow modules to specify the first filter in a sub_request when
1977 making the sub_request. This keeps modules from having to change the
1978 output_filter immediately after creating the sub-request, and therefore
1979 skip the sub_req_output_filter. [Ryan Bloom]
1981 *) Update ab to accept URLs with IPv6 literal address strings (in the
1982 format described in RFC 2732), and to build Host header fields in
1983 the same format. This allows IPv6 literal address strings to be
1984 used with ab. This support has been tested against Apache 1.3 with
1985 the KAME patch, but Apache 2.0 does not yet work with this format
1986 of the Host header field. [Jeff Trawick]
1988 *) Accomodate an out-of-space condition in the piped logs and the
1989 rotatelogs.c code, and no longer churn log processes for this
1990 condition. [Victor J. Orlikowski]
1992 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1995 Changes with Apache 2.0a8
1997 *) Add a directive to mod_mime so that filters can be associated with
2001 *) Get multi-views working again. We were setting the path_info
2002 field incorrectly if we couldn't find the specified file.
2005 *) Fix 304 processing. The core should never try to send the headers
2006 down the filter stack. Always, just setup the table in the request
2007 record, and let the header filter convert it to data that is ready
2011 *) More fixes for the proxy. There are still bugs in the proxy code,
2012 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
2016 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
2019 *) APR: Add new apr_getopt_long function to handle long options.
2020 [B. W. Fitzpatrick <fitz@red-bean.com>]
2022 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
2023 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
2024 hostname resolution/address string parsing and building
2025 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
2026 of one of the apr_sockaddr_t structures for a socket. Change
2027 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
2029 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
2030 I have proxied pages with it, cleanup will commence soon.
2033 *) Make the proxy work with filters. This isn't perfect, because we
2034 aren't dealing with the headers properly. [Ryan Bloom]
2036 *) Do not send a content-length iff the C-L is 0 and this is a head
2037 request. [Ryan Bloom]
2039 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
2040 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
2042 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
2044 *) Get the default_handler to stop trying to deal with HEAD requests.
2045 The idea is to let the content-length filter compute the C-L before
2046 we try to send the data. If we can get the C-L correctly, then we
2047 should send it in the HEAD response.
2050 *) The Header filter can now determine if a body should be sent based
2051 on r->header_only. The general idea of this is that if we delay
2052 deciding to send the body, then we might be able to compute the
2053 content-length correctly, which will help caching proxies to cache
2054 our data better. Any handler that doesn't want to try to compute
2055 the content-length can just send an EOS bucket without data and
2056 everything will just work.
2059 *) Add the referer to the error log if one is available.
2060 [Markus Gyger <mgyger@itr.ch>]
2062 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
2063 change, the root of the configuration tree has been exposed to modules
2065 [Ryan Morgan <rmorgan@covalent.net>]
2067 *) Get the core_output_filter to use the bucket interface directly.
2068 This keeps us from calling the content-length filter multiple times
2069 for a simple static request.
2072 *) We are sending the content-type correctly now.
2073 [Ryan Bloom and Will Rowe]
2075 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
2076 a bogus bytes-sent value when the only thing being sent was trailers
2077 and writev() returned an error (or EAGAIN). [Jeff Trawick]
2079 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
2080 hints file to determine which platforms define
2081 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2084 *) APR: add apr_get_home_directory() [Jeff Trawick]
2086 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
2088 *) Not all platforms have INADDR_NONE defined by default. Apache
2089 used to make this check and define INADDR_NONE if appropriate,
2090 but APR needs the check too, and I suspect other applications will
2091 as well. APR now defines APR_INADDR_NONE, which is always a valid
2092 value on all platforms.
2093 [Branko Èibej <brane@xbc.nu>]
2095 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
2096 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
2098 *) Relax the syntax checking of Host: headers in order to support
2099 iDNS. PR#6635 [Tony Finch]
2101 *) When reading from file buckets we convert to an MMAP if it makes
2102 sense. This also simplifies the default handler because the
2103 default handler no longer needs to try to create MMAPs.
2106 *) BUFF has been removed from the main server. The BUFF code will remain
2107 in the code until it has been purged from the proxy module as well.
2110 *) Byteranges have been completely re-written to be a filter. This
2111 has been tested, and I believe it is working correctly, but it could
2112 doesn't work for the Adobe Acrobat plug-in. The output almost matches
2113 the output from 1.3, the only difference being that 1.3 includes
2114 a content-length in the response, and this does not.
2117 *) APR read/write functions and bucket read functions now operate
2118 on unsigned integers, instead of signed ones. It doesn't make
2119 any sense to use signed ints, because we return the error codes,
2120 so if we have an error we should report 0 bytes read or written.
2123 *) Always compute the content length, whether it is sent or not.
2124 The reason for this, is that it allows us to correctly report
2125 the bytes_sent when logging the request. This also simplifies
2126 content-length filter a bit, and fixes the actual byte-reporing
2127 code in mod_log_config.c
2130 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
2131 it says, because it was only used by EOS and FLUSH buckets. Since
2132 neither of those are required at the end of a brigade, this was
2133 really signifying FLUSH_THE_DATA, but that can be determined better
2134 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
2135 buckets now return a length of 0, which is actually the amount of data
2136 read, so they make more sense.
2139 *) Allow the core_output_filter to save some data past the end of a
2140 request. If we get an EOS bucket, we only send the data if it
2141 makes sense to send it. This allows us to pipeline request
2142 responses. As a part of this, we also need to allocate mmap
2143 buckets out of the connection pool, not the request pool. This
2144 allows the mmap to outlive the request.
2147 *) Make blocking and non-blocking bucket reads work correctly for
2148 sockets and pipes. These are the only bucket types that should
2149 have non-blocking reads, because the other bucket types should
2150 ALWAYS be able to return something immediately.
2153 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
2154 server, but use Ctrl+Break to initiate a graceful restart
2155 instead of duplicating behavior. [John Sterling]
2157 *) Patch mod_autoindex to set the Last-Modified header based on
2158 the directory's mtime, and add the ETag header. [William Rowe]
2160 *) Merge the 1.3 patch to add support for logging query string in
2161 such a way that "%m %U%q %H" is the same as "%r".
2164 *) Port three log methods from mod_log_config 1.3 to 2.0:
2165 CLF compliant '-' byte count, method and protocol.
2168 *) Add a new LogFormat directive, %c, that will log connection
2169 status at the end of the response as follows:
2170 'X' - connection aborted before the response completed.
2171 '+' - connection may be kept-alive by the server.
2172 '-' - connection will be closed by the server.
2175 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2176 Unicode file names and paths for Win32, and tag the Content-Type
2177 from mod_autoindex to reflect that charset if the the feature
2178 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2180 *) Compute the content length (and add appropriate header field) for
2181 the response when no content length is available and we can't use
2182 chunked encoding. [Jeff Trawick]
2184 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2185 so that content input filters get dechunked data when using
2186 the default handler. Also removed REQUEST_CHUNKED_PASS.
2189 *) Add mod_ext_filter as an experimental module. This module allows
2190 the administrator to use external programs as filters. Currently,
2191 only filtering of output is supported. [Jeff Trawick]
2193 *) Most Apache functions work on EBCDIC machines again, as protocol
2194 data is now translated (again). [Jeff Trawick]
2196 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2197 the EBCDIC support. They are noops on ASCII machines, so this
2198 type of translation doesn't have to be surrounded by #ifdef
2199 CHARSET_EBCDIC. [Jeff Trawick]
2201 *) Fix mod_include. tag commands work again, and the server will
2202 send the FAQ again. This also allows mod_include to set aside
2203 buckets that include partial buckets.
2204 [Ryan Bloom and David Reid]
2206 *) Add suexec support back. [Manoj Kasichainula]
2208 *) Lingering close now uses the socket directly instead of using
2209 BUFF. This has been tested, but since all we can tell is that it
2210 doesn't fail, this needs to be really hacked on.
2213 *) Allow filters to modify headers and have those headers be sent to
2214 the client. The idea is that we have an http_header filter that
2215 actually sends the headers to the network. This removes the need
2216 for the BUFF to send headers.
2219 *) Charset translation: mod_charset_lite handles translation of
2220 request bodies. Get rid of the xlate version of ap_md5_digest()
2221 since we don't compute digests of filtered (e.g., translated)
2222 response bodies this way anymore. (Note that we don't do it at
2223 all at the present; somebody needs to write a filter to do so.)
2226 *) Input filters and ap_get_brigade() now have a input mode parameter
2227 (blocking, non-blocking, peek) instead of a length parameter.
2230 *) Update the mime.types file to the registered media types as
2231 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2234 *) Namespace protect some macros declared in ap_config.h
2237 *) Support HTTP header line folding with input filtering.
2240 *) Mod_include works again. This should still be re-written, but at
2241 least now we can serve an SHTML page again.
2244 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2245 to both the BUFF and the socket in the conn_rec. Functions that
2246 want to use the BUFF can, functions that want to use the socket,
2247 can. They point to the same place.
2250 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2251 [Tomas "Ögren" <stric@ing.umu.se>]
2253 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2254 associated pool goes away. (APR pipes on OS/2 were already had this
2255 logic.) This resolvs a fatal file descriptor leak with CGIs.
2258 *) The final line of the config file was not being read if there was
2259 no \n at the end of it. This was caused by apr_fgets returning
2260 APR_EOF even though we had read valid data. This is solved by
2261 making cfg_getline check the buff that was returned from apr_fgets.
2262 If apr_fgets return APR_EOF, but there was data in the buf, then we
2263 return the buf, otherwise we return NULL.
2266 *) Piped logs work again in the 2.0 series.
2269 *) Restore functionality broken by the mod_rewrite security fix:
2270 rewrite map lookup keys and default values are now expanded
2271 so that the lookup can depend on the requested URI etc.
2272 PR #6671 [Tony Finch]
2274 *) Tighten up the syntax checking of Host: headers to fix a
2275 security bug in some mass virtual hosting configurations
2276 that can allow a remote attacker to retrieve some files
2277 on the system that should be inaccessible. [Tony Finch]
2279 *) Add a pool bucket type. This bucket is used for data allocated out
2280 of a pool. If the pool is cleaned before the bucket is destroyed, then
2281 the data is converted to a heap bucket, allowing it to survive the
2285 *) Add a flush bucket. This allows modules to signal that the filters
2286 should all flush whatever data they currently have. There is no way
2287 to actually force them to do this, so if a filter ignores this bucket,
2288 that's life, but at least we can try with this.
2291 *) Add an output filter for sub-requests. This filter just strips the
2292 EOS bucket so that we don't confuse the main request's core output
2293 filter by sending multiple EOS buckets. This change also makes sub
2294 requests start to send EOS buckets when they are finished.
2297 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2298 makes ap_bucket_destroy a return void, which is okay because it
2299 used to always return APR_SUCCESS, and nobody ever checked its
2300 return value anyway.
2301 [Cliff Woolley <cliffwoolley@yahoo.com>]
2303 *) Remove the index into the bucket-type table from the buckets
2304 structure. This has now been replaced with a pointer to the
2305 bucket_type. Also add some macros to test the bucket-type.
2308 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2309 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2310 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2311 All _VAR_ flavors changes to _DATA to be absolutely clear.
2314 *) Add support for /, //, //servername and //server/sharename
2315 parsing of <Directory> blocks under Win32 and OS2.
2316 [Tim Costello, William Rowe, Brian Harvard]
2318 *) Remove the function pointers from the ap_bucket type. They have been
2319 replaced with a global table. Modules are allowed to register bucket
2320 types and use then use those buckets.
2323 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2324 once we finish writing the request body to the cgi child process;
2325 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2326 worked without this change (for reasons I don't understand), but large
2327 ones didn't. [Jeff Trawick]
2329 *) Remove file bucket specific information from the ap_bucket type.
2330 This has been moved to a file_bucket specific type that hangs off
2331 the data pointer in the ap_bucket type.
2334 *) Input filtering now has a third argument. This is the amount of data
2335 to read from lower filters. This argument can be -1, 0, or a positive
2336 number. -1 means give me all the data you have, I'll deal with it and
2337 let you know if I need more. 0 means give me one line and one line
2338 only. A positive number means I want no more than this much data.
2340 Currently, only 0 and a positive number are implemented. This allows
2341 us to remove the remaining field from the conn_rec structure, which
2345 *) Big cleanup of the input filtering. The goal is that http_filter
2346 understands two conditions, headers and body. It knows where it is
2347 based on c->remaining. If c->remaining is 0, then we are in headers,
2348 and http_filter returns a line at a time. If it is not 0, then we are
2349 in body, and http_filter returns raw data, but only up to c->remaining
2350 bytes. It can return less, but never more.
2351 [Greg Ames, Ryan Bloom, Jeff Trawick]
2353 *) mod_cgi: Write all of the request body to the child, not just what
2354 the kernel would accept on the first write. [Jeff Trawick]
2356 *) Back out the change that moved the brigade from the core_output_filters
2357 ctx to the conn_rec. Since all requests over a given connection
2358 go through the same core_output_filter, the ctx pointer has the
2362 *) Fix another bug in the send_the_file() read/write loop. A partial
2363 send by apr_send would cause unsent data in the read buffer to
2364 get clobbered. Complete making send_the_file handle partial
2365 writes to the network.
2368 *) Fix a couple of type fixes to allow compilation on AIX again
2369 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2371 *) Fix bug in send_the_file() which causes offset to be ignored
2372 if there are no headers to send.
2375 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2376 filter. Useful for supporting Windows 9* with a binary
2377 compiled on Windows NT.
2380 Changes with Apache 2.0a7
2382 *) Reimplement core_output_filter to buffer/save bucket brigades
2383 across multiple calls to the core_filter. The brigade will be
2384 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2385 thresholds are hit or the EOS bucket is received.
2388 *) Create experimental filter (buffer_filter) that coalesces bytes
2389 into one large buffer before invoking the next filter in the
2390 chain. This filter is particularly useful with the current
2391 implementation of mod_autoindex when it inserted above the
2392 chunk_filter. mod_autoindex generates a lot of brigades that
2393 containing buckets holding just a few bytes each. The
2394 buffer_filter coalesces these buckets into a single large bucket.
2397 *) Add apr_sendfile() support into the core_output_filter.
2400 *) Add apr_sendv() support into the core_output_filter.
2403 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2404 [Mike Abbott <mja@sgi.com>]
2406 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2407 make much sense, because Apache uses buckets instead of BUFFs now.
2410 *) send_the_file now falls back to a read/write loop on platforms that
2411 do not have sendfile.
2412 [Ryan Bloom and Brian Havard]
2414 *) Install apachectl correctly, and substitute the proper values so
2415 that it works again. [Ryan Bloom]
2417 *) Better(??) handle platforms that lack sendfile().
2420 *) APR now has UUID generation/formatting/parsing support.
2423 *) Begin the http_filter. This is an input filter that understands
2424 the absolute basic amount required to parse an HTTP Request. The
2425 goal is to be able to split headers from request body before passing
2426 the data back to the other filters.
2429 *) Bring forward from 1.3.13 the config directory implementation
2432 *) install apxs if it is created
2435 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2436 conversions. [William Rowe]
2438 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2439 ap_add_output_filter(). [Jeff Trawick]
2441 *) Multiple build and configuration fixes
2444 -add datadir and localstatedir substitutions
2446 -fix logfilename misspelling
2447 -fix evaluation of installation dir variables and
2448 -replace $foobar by $(foobar) to be usefull in the makefile
2452 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2453 $CC_FOR_BUILD is still missing
2454 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2455 -add missing "AR=@AR@" to severaly Makefile.in's
2456 -cache result for "struct rlimit"
2457 -compile all helper programs with native and cross compiler
2458 and use the native version to generate header file
2459 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2461 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2463 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2465 *) Fix a bug where a client which only sends \n to delimit header
2466 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2467 message. Start working on ebcdic co-existance with input
2469 [William Rowe, Greg Ames]
2471 *) If mod_so is enabled in the server always create libexec, even
2472 if there are no modules installed in this directory. This is a
2473 requirement for APXS to work correctly.
2476 *) Connection oriented output filters are now stored in the
2477 conn_rec instead of the request_rec. This allows us to add the
2478 output filter in the pre-connection phase instead of the
2479 post_read_request phase, which keeps us from trying to write an
2480 error page before we have a filter to write to the network.
2481 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2483 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2484 mmap can be used across multiple buckets (default_handler with
2485 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2486 the mmap itself can't be associated with the bucket.
2489 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2492 *) Radical surgery to improve mod_isapi support under Win32.
2493 Includes a number of newer ServerSupportFunction calls, support
2494 for ReadClient (in order to retrieve POSTs greater than 48KB),
2495 and general bug fixes to more reliably load ISAPI .dll's and
2496 prevent leaking handle resources. Note: There are still
2497 discrepancies between IIS's and Apache's ServerVariables, and
2498 async calls are still not supported. Additional warnings are
2499 logged to facilitate debugging of unsupported ISAPI calls.
2502 *) Add input filtering to Apache. The basic idea for the input
2503 filters is the same as the ideas for output filters. The biggest
2504 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2505 should be called, and the order of execution for the filter itself is
2506 different. When writing an output filter, a brigade is passed in,
2507 and filters operate directly on that brigade, when done, they call
2508 ap_pass_brigade. Input filters are the exact opposite. Because input
2509 is not a push operation, filters first call ap_get_brigade. When this
2510 function returns, the input filter will be left with a valid brigade.
2511 The input filter should then operate on the brigade, and return.
2514 *) Fix building on BSD/OS using its native make. The build system
2515 falls back to the BSD .include directive on that host platform.
2518 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2519 SHA1 and plaintext password encodings. Make feature tests a
2520 bit more flexible. [William Rowe]
2522 *) Charset translation: mod_charset_lite handles output content
2523 translation in a filter. mod_charset_lite no longer ignores
2524 subrequests. A bunch of cruft related to BUFF's support for
2525 translating request and response bodies was removed.
2528 *) Move the addition of the CORE filter to the post_read_request
2529 hook in http_core.c. This removes the need to add the filter in
2530 multiple places and allows for an SSL module to be added much
2531 simpler. [Ryan Bloom]
2533 *) Fix a security problem that affects certain configurations of
2534 mod_rewrite. If the result of a RewriteRule is a filename that
2535 contains expansion specifiers, especially regexp backreferences
2536 $0..$9 and %0..%9, then it may be possible for an attacker to
2537 access any file on the web server. [Tony Finch]
2539 *) Fix a bug where errors that are detected during early request parsing
2540 don't produce visible HTTP error messages at the browser, because
2541 the core_filter wasn't present. [Greg Ames]
2543 *) Provide apr_socklen_t as a portability aid.
2544 [Victor J. Orlikowski]
2546 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2547 as well as a comment arg to the add, adduser and update cmds.
2548 update allows the user to clear or preserve pw/groups/comment.
2549 Fixed a bug in dbmmanage that prevented the check option from
2550 parsing a password followed by :group... text. Corrected the
2551 seed calcualation for Win32 systems, and added -lsdbm support.
2554 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2557 *) Avoid a segfault when parsing .htaccess files. An
2558 uninitialized tree pointer was passed to ap_build_config().
2561 *) Change the way that inet_addr & inet_network are checked for
2562 in APR's configure process to allow BeOS BONE to correctly
2563 find them. With this change BeOS BONE now builds from source
2564 with no problems. [David Reid]
2566 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2567 the end of the parameters to execve() was stored in the wrong
2568 location, overlaying the storage beyond the newargs[] array and
2569 also passing uninitialized storage to execve(), which would
2570 sometimes fail with EFAULT. [Jeff Trawick]
2572 *) Fix a bug parsing configuration file containers. With a sequence
2573 like this in the config file
2575 <IfModule mod_kilroy.c>
2578 <IfModule mod_lovejoy.c>
2583 the second container would be terminated at the blank line due to
2584 sediment in the buffer from reading the prior </IfModule> and an
2585 error message would be generated for the real </IfModule> for the
2586 second container. Also due to this problem, any two characters
2587 could be used for "</" in the close of a container.
2590 *) ap_add_filter prototype changed to remove the ctx pointer. The
2591 pointer still remains in the filter structure, but it can not be
2592 a part of the ap_add_filter prototype. The reason is that when
2593 the core uses AddFilter to add a filter to the stack it doesn't
2594 know how to allocate the ctx pointer, or even how much memory should
2595 be allocated. The filters will have to be responsible for allocating
2596 the ctx memory when they need it.
2599 *) Add an AddFilter directive. This directive takes a list of filters
2600 that should be activated for the requested resource.
2603 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2604 some other platforms). [Jeff Trawick]
2606 *) Modify mod_include to be a filter. Currently, it has only been tested
2607 on actual files, but it should work for CGI scripts too.
2610 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2611 writes. apr_flush() for Unix: handle interrupted writes.
2614 *) NameVirtualHost can now take "*" as an argument instead of
2615 an IP address. This allows you to create a purely name-based
2616 virtual hosting server that does not have any IP addresses in
2617 the configuration file and which ignores the local address
2618 of any connections. PR #5595, PR #4455 [Tony Finch]
2620 *) Fix some compile warnings in mod_mmap_static.c
2621 [Mike Abbott <mja@sgi.com>]
2623 *) Fix chunking problem with CGI scripts. The general problem was that
2624 the CGI modules were adding an EOS bucket and then the core added an
2625 EOS bucket. The chunking filter finalizes the chunked response when it
2626 encounters an EOS bucket. Because two EOS buckets were sent, we
2627 finalized the response twice. The fix is to make sure we only send one
2628 EOS, by utilizing a flag in the request_rec.
2631 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2632 and Win32. Previously, the first read from an apr_file_t set up via
2633 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2635 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2636 bucket, instead of using BUFF's and ap_r*.
2639 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2640 [Mike Abbott <mja@sgi.com>]
2642 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2643 code to use APR file's directly instead of going through BUFFs.
2646 *) Fix compile break on some platforms for mod_mime_magic.c
2647 [John K. Sterling <sterling@covalent.net>]
2649 *) Fix merging of AddDefaultCharset directive.
2650 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2652 *) Minor revamp of the rlimit sections of code. We now test
2653 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2654 is now "available" even if the platform doesn't support
2655 the rlimit family (it's just a noop though). [Jim Jagielski]
2657 *) Migrate the pre-selection of which MPM to use for specific
2658 platforms to hints.m4, which contains (or should contain)
2659 all platform specific "hints". [Jim Jagielski]
2661 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2664 *) Add tables with non-string/binary values to APR.
2667 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2670 *) Update PCRE to version 3.2. [Ryan Bloom]
2672 *) Change the way buckets' destroy functions are called so that
2673 they can be more directly used when changing the type of a
2674 bucket in place. [Tony Finch]
2676 *) Add generic support for reference-counting the resources used by
2677 buckets, and alter the HEAP and MMAP buckets to use it. Change
2678 the way buckets are initialised to support changing the type of
2679 buckets in place, and use it when setting aside TRANSIENT buckets.
2680 Change the implementation of TRANSIENT buckets so that it can be
2681 mostly shared with IMMORTAL buckets, which are now implemented.
2684 Changes with Apache 2.0a6
2686 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2688 *) Add a chunking filter to Apache. This brings us one step closer
2689 to removing BUFF. [Ryan Bloom]
2691 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2692 added to the stack is the last filter to be called. [Ryan Bloom]
2694 *) Apache 2.0 has been completely documented using Scandoc. The
2695 docs can be generated by running 'make docs'. [Ryan Bloom]
2697 *) Add filtered I/O to Apache. This is based on bucket brigades,
2698 Currently the buckets still use BUFF under the covers, but that
2699 should change quickly. The only currently written filter is the
2700 core filter which just calls ap_bwrite. [The Apache Group]
2702 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2703 built with thread support. [Jeff Trawick]
2705 *) Abort configuration if --with-layout was specified and there's
2706 no layout definition file. [Ken Coar]
2708 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2710 *) Add support for extension methods for the Allow response header
2711 field, and an API routine for accessing r->allowed and the
2712 list of extension methods in a unified manner. [Ken Coar]
2714 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2715 [Rob Simonson <simo@us.ibm.com>]
2717 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2718 APACHE_XLATE builds. [Jeff Trawick]
2720 *) A configuration file parsing problem was fixed. When the
2721 configuration file started with an IfModule/IfDefine container,
2722 only the last statement in the container would be retained.
2725 Changes with Apache 2.0a5
2727 *) Perchild is serving pages after passing them to different child
2728 processes. There are still a lot of bugs, but this does work. I
2729 have made requests against the same installation of Apache, and had
2730 different servers use different user IDs to serve the responses.
2731 This change moves to using socketpair instead of an AF_UNIX socket.
2734 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2735 It can't seem to pass between child processes yet, but I think we
2736 are closer now than before. This moves us back to using Unix
2737 Domain Sockets. [Ryan Bloom]
2739 *) libapr functions and types renamed with apr_ prefix.
2740 #include "apr_compat.h" for 1.3.x backwards compat
2743 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2744 return the right information on the local socket address.
2745 [Gregory Nicholls <gnicholls@level8.com>]
2747 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2748 [Gregory Nicholls <gnicholls@level8.com>]
2750 *) Add an option to not detach from the controlling terminal without
2751 going into single process mode. This allows for much easier
2752 debugging of the process startup code. [Ryan Bloom]
2754 *) ab: don't use perror() to report the failure of an APR function.
2757 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2758 scoreboard on graceful restarts.
2761 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2762 An invalid ap_proc_t was passed to ap_create_process().
2765 *) Allow modules to register filters. Those filters are still
2766 never called, but this is a step in the right direction.
2767 [Ryan Bloom and Greg Stein]
2769 *) Register the mod_cgid daemon process for cleanup so that it is
2770 killed at termination if it does not die when the parent gets
2771 SIGTERM. This change is to fix occasional problems where the
2772 process stays around. Bugs in similar logic in mod_rewrite and
2773 mod_include were also fixed. [Jeff Trawick]
2775 *) Fix a bug in the time handling. Basically, we were imploding a time
2776 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2777 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2778 uses those two fields to adjust the time value. Because of the HTTP
2779 spec, both of those values can be zero'ed out safely. This fixes
2780 the bug correctly. [Ryan Bloom]
2782 *) Fix a couple of place in the Windows code where the wrong error
2783 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2785 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2787 *) Added the APR_EOL_STR macro for platform dependent differences in
2788 logfiles and other raw text (such as all APR files). Fixes logfiles
2789 not terminated with cr/lf sequences in Win32. [William Rowe]
2791 *) Move all strings functions in APR to src/lib/apr/strings and create
2792 apr_strings.h for the prototypes. [Ryan Bloom]
2794 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2795 to repeat the syscall until we stop getting EINTR. I noticed a
2796 related problem at termination (SIGTERM) on FreeBSD when using
2797 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2798 implementation work properly with child init. Previously, ap_lock()
2799 was essentially a no-op because all children were using different
2800 locks and thus nobody ever blocked. [Jeff Trawick]
2802 *) The htdocs/ tree has been moved out of the CVS source tree into
2803 a separate area for easier development. This has NO EFFECT on
2804 end-users or Apache installations. [Ken Coar]
2806 *) Integrate the mod_dav module for WebDAV protocol handling. This
2807 adds the dav and dav_fs modules, the SDBM library, and additional
2808 XML handling utilities. [Greg Stein]
2810 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2813 *) Update the lib/expat-lite/ library (bring forward changes from
2814 the Apache 1.3 repository). [Greg Stein]
2816 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2817 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2819 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2820 machines where sendfile is detected, but nobody has written ap_sendfile.
2821 [Dave Hill <ddhill@zk3.dec.com>]
2823 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2825 *) ab would start up more connections than needed, then quit when the
2826 desired number were finished. Also fixed a logic error involving
2827 ab keepalives. [Victor J. Orlikowski]
2829 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2830 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2831 timeouts (i.e, if a timeout was specified, the pipe reverted to
2832 a full blocking pipe). Now the behaviour is more in line with
2833 Unix non-blocking pipes.
2836 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2837 cache open file handles along with accept socket reuse enables
2838 Apache 2.0 to serve non-keepalive requests for static files at
2839 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2840 and Apache 2.0 will serve almost 1200 rps on my system).
2843 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2844 supports two config directives, mmapfile (same behavious as
2845 mod_mmap_static) and cachefile. Use the cachefile directive
2846 to cache open file handles. This directive only works on systems
2847 that have implemented the ap_sendfile API. cachefile works today
2848 on Windows NT, but has not been tested on any flavors of Unix.
2851 *) Cleanup the configuration. With the last few changes the
2852 configuration process automatically:
2853 inherits information about how to build from APR. Allowing
2854 APR to inform Apache that it should or should not use -ldl
2856 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2857 based on the threading model
2859 Apache calls APR's configure process before finishing it's
2860 configuration processing, allowing for more information flow
2865 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2866 with non-zero argument makes the socket non-blocking. BeOS and
2867 OS/2 already worked this way. [Jeff Trawick]
2869 *) ap_close() now calls ap_flush() for buffered files, so write
2870 operations work a whole lot better on buffered files.
2873 *) Fix error messages issued from MPMs which explain where to change
2874 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2877 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2878 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2879 now the way that the blocking state of a pipe is manipulated.
2880 ap_block_pipe() is gone. [Jeff Trawick]
2882 *) Correct the problem where the only local host name that the IP stack
2883 can discover are 'undotted' private names. If no fully qualified
2884 domain name can be identified, the default ServerName will be set to
2885 the machine's IP address string. A warning is always provided if the
2886 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2888 *) Repair problems with config file processing which caused segfault
2889 at init when virtual hosts were defined and which caused ServerName to
2890 be ignored when there was no valid DNS setup. [Jeff Trawick]
2892 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2894 *) Add ap_sendfile implementation for AIX
2895 [Victor J. Orlikowski]
2897 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2898 apr_network_io.h, and apr_thread_proc.h.
2899 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2901 *) Bring the allocation and pool debugging code back into a working
2902 state. This will need to be tested as so far it's only been used on
2905 *) Change configuration command setup to be properly typesafe when in
2906 maintainer mode. Note that this requires a compiler that can initialise
2907 unions. [Ben Laurie]
2909 *) Turn on buffering for config file reads. Part of this was to
2910 repair buffered I/O support in Unix and implement buffered
2911 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2913 *) Win32: Fix problem where UTC offset was not being set correctly
2914 in the access log. Problem reported on news group by Jerry Baker.
2917 *) Fix segfault when reporting this type of syntax error:
2918 "</container> without matching <container> section", where
2919 container is VirtualHost or Directory or whatever.
2922 *) Prevent the source code for CGIs from being revealed when using
2923 mod_vhost_alias and the CGI directory is under the document root
2924 and a user makes a request like http://www.example.com//cgi-bin/cgi
2925 as reported in <news:960999105.344321@ernani.logica.co.uk>
2928 *) Add support for the new Beos NetwOrking Environment (BONE)
2931 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2932 final input char is incomplete; ap_bwrite_xlate() now handles
2933 incomplete final input chars. [Jeff Trawick]
2935 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2936 that a bhalfduplex call occurs before logging or else DNS and
2937 such can delay the last packet of the response. [Dean Gaudet]
2939 *) Some syscall reduction in APR on unix -- don't seek when setting
2940 up an mmap; and don't fcntl() more than once per socket.
2943 *) When mod_cgid is started as root, the cgi daemon now switches
2944 to the configured User/Group (like other httpd processes)
2945 instead of continuing as root. [Jeff Trawick]
2947 *) The prefork MPM now uses an APR lock for the accept() mutex.
2948 It has not been getting a lock at all recently. httpd -V now
2949 displays APR's selection of the lock mechanism instead of the
2950 symbols previously respected by prefork. [Jeff Trawick]
2952 *) Change the mmap() feature test to check only for existence.
2953 The previous check required features not used by Apache.
2956 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2957 sometimes mangled. The len parm to accept() was not
2958 initialized, leading sometimes to an endless loop of failed
2959 accept() calls on OS/390 and anywhere else that failed the call
2960 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2961 instead of declaring it ourselves to fix a compilation problem
2962 on Solaris. [Jeff Trawick]
2964 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2966 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2968 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2970 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2971 initialization if ALLOC_DEBUG is defined; no known symptom
2972 otherwise. [Jeff Trawick]
2974 *) Fix typo in configure script when checking for mod_so. bash
2975 doesn't seem to have a problem but /bin/sh on Solaris does.
2976 Symptom: "./configure: test: unknown operator =="
2979 *) Rebind the Win32 NT and 9x services control into the MPM.
2980 All console, WinNT SCM and Win9x pseudo-service control code is
2981 now wrapped within the WinNT MPM.
2984 *) Make a copy of getenv("PATH") before storing for later use. Some
2985 getenv() implementations use the same storage for successive calls.
2986 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2988 *) Server Tokens work in 2.0 again. This also propogates the change
2989 to allow just the product name in the server string using
2993 Changes with Apache 2.0a4
2995 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2996 won't need to call it. [Greg Ames, Jeff Trawick]
2998 *) Move pre_config hook call to between configuration read and config
2999 tree walk. This allows all modules to implement pre_config hooks
3000 and know that they will be called at an appropriate time.
3003 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
3006 *) Add pre-config hooks back to all modules.
3009 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
3010 ContentDigest enabled and we can't/don't mmap the file.
3013 *) We now report the correct line number for syntax errors in config
3014 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
3016 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
3017 related bugs, and changed shmem/locking to use apr API. Shared-mem
3018 is currently disabled, however, because of problems with graceful
3019 restarts. [Ronald Tschalär]
3021 *) Fix corruption of IFS variable in --with-module= handling.
3022 Depending on the user's shell or customization thereof, there
3023 would be errors generating ap_config_auto.h later in the configure
3024 procedure. [Jeff Trawick]
3026 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
3027 isn't used (as in 1.3), except that on Unix it is now logged via
3028 ap_log_rerror() instead of by the child having STDERR_FILENO refer
3029 to the error log. [Greg Ames, Jeff Trawick]
3031 *) Add '-D' argument processing for run time configuration defines.
3034 *) Organize http_main.c as independent code, such that no code or
3035 global data is exported from it. WIN32 will dynamically link it
3036 to the server core, so this will prevent mutual dependency.
3039 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
3040 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
3043 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
3044 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
3046 *) Add mod_charset_lite for configuring character set translation.
3049 *) Add '-n' option to htpasswd to make it print its user:pw record
3050 on stdout rather than having to frob a text file. [Ken Coar]
3052 *) Fix saferead. Basically, we flush the output buffer if a read on the
3056 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
3057 a conversion is single-byte only. [Jeff Trawick]
3059 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
3060 the BeOS 5.0 documentation says that shutdown doesn't work yet.
3063 *) Fix some minor errors where pid was being manipulated as an int
3064 instead of the portable pid_t. [Roy Fielding]
3066 *) Fix some error log prints that were printing the pointer to a
3067 structure rather than the pid within the structure.
3068 [Jeff Trawick, Roy Fielding]
3070 *) ab: Fix a command-line processing bug; track bad headers in
3071 err_response; support reading headers up to 2K.
3072 [Ask Bjoern Hansen <ask@valueclick.com>]
3074 *) Fix ap_resolve_env() so that it handles new function added in a prior
3075 alpha (see "Added the capability to do ${ENVVAR} constructs in the
3076 config file.") as well as the constructs used by mod_rewrite.
3077 [Paul Reder <rederpj@raleigh.ibm.com>]
3079 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
3081 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
3082 APR to perform translation, instead of accessing the hard-coded tables
3083 in 1.3's ebcdic.c. [Jeff Trawick]
3085 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
3088 *) Add the ability to hook into the config file reading phase. Basically
3089 if a directive is specified EXEC_ON_READ, then when that directive is
3090 read from the config file, the assocaited function is executed. This
3091 should only be used for those directives that must muck with HOW the
3092 server INTERPRETS the config. This should not be used for directives
3093 that re-order or replace items in the config tree. Those changes should
3094 be made in the pre-config step.
3097 *) Add mod_example to the build system.
3100 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
3101 byte character sets. [Jeff Trawick]
3103 *) Pick up various EBCDIC fixes from 1.3 (from Martin
3104 Kraemer and Oliver Reh originally according to the change log).
3107 *) Fix a couple of problems in RFC1413 support (controlled by the
3108 IdentityCheck directive). Apache did not build the request string
3109 properly and more importantly Apache would loop forever if the
3110 would-be ident server dropped the connection before sending a
3111 properly terminated response. [Jeff Trawick]
3113 *) apxs works in 2.0.
3116 *) Reliable piped logs work in 2.0.
3119 *) Introduce a hash table implementation into APR to be used for
3120 replacing tables and other random data structures in Apache.
3123 *) Add some more error reporting to htpasswd in the case of problems
3124 generating or accessing the temporary file. Also, pass in a
3125 buffer if the implementation knows how to use it (i.e., if L_tmpnam
3126 is defined). [Ken Coar]
3128 *) Configure creates config.nice now containing your configure
3129 options. Syntax: ./config.nice [--more-options]
3132 *) Fix various return code problems in APR on Win32. For most of
3133 these, APR was returning APR_EEXIST instead of GetLastError()/
3134 WSAGetLastError(). [Jeff Trawick]
3136 *) Make piped logs work again in version 2.0
3139 *) Add VPATH support to UNIX build system of Apache and APR.
3142 *) Fix ap_tokenize_to_argv to respect the const arguments that are
3146 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
3147 Patch submitted to author.
3150 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
3151 /sbin in PATH on FreeBSD (all submitted to rse previously)
3154 *) Fix building Pthread-based MPMs on OpenBSD
3155 [Sascha Schumann] PR#26
3157 *) Fix ap_readdir() problem on systems where d_name[] field in
3158 struct dirent is declared with only one byte. (This problem only
3159 affected multithreaded builds.) This caused a segfault during
3160 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3161 least). [Jeff Trawick]
3163 *) Fix some make-portability problems on at least Tru64, Irix
3165 [Sascha Schumann] PR#18, PR#39
3167 *) Add ap_sigwait() to support old-style sigwait() on systems
3168 like OS/390 and UnixWare.
3171 *) Add POSIX-thread flags for more platforms.
3174 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3175 (on Unix, at least) to handle resolver errors. Fix a bug in
3176 the definition of APR_ENOMEM so that ap_strerror() can spit
3177 out the correct error message for it.
3180 Changes with Apache 2.0a3
3182 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3185 *) API: *HOOK* macros now have an AP_ prefix
3188 *) Win32: Eliminate redundant calls to initialize winsock.
3189 [Tim Costello <timcostello@ozemail.com.au>]
3191 *) Fix bugs initializing ungetchar for pipes.
3192 [Chia-liang Kao <clkao@CirX.ORG>]
3194 *) The ab program in the src/support directory is now portable using
3198 *) Support directory is being compiled when the server is built
3201 *) The configure option --with-program-name has been added to allow
3202 developers to rename the executable at configure time. This also
3203 changes the name of the config files to match the executable's name.
3206 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3207 containing version numbers. [Martin Pool]
3209 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3210 Unix; access_log and error_log now created with these perms; non-
3211 Unix is unaffected [Jeff Trawick]
3213 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3214 Replaced more magic numbers with MD5_DIGESTSIZE.
3215 [William Rowe, Roy Fielding]
3217 *) Win32: Get mod_auth_digest compiling and added to the Windows
3218 build environment. Not tested and I'd be suprised if it
3219 actually works. [Bill Stoddard]
3221 *) Revamp the Win32 make environment. Makefiles have been removed and
3222 Apache.dsw created to bring together all the pieces. Create new file
3223 os/win32/BaseAddr.ref to define module base addresses (to prevent
3224 dll relocation at start-up).
3225 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3227 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3228 of the \015, \012, and \015\012 constants with macros.
3229 [Greg Ames <gregames@us.ibm.com>]
3231 *) Add ap_xlate_open() et al for translation of text between different
3232 character sets. The initial implementation requires iconv().
3235 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3236 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3238 *) CGI output is being timed out now.
3241 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3242 is used by the new apr file. There is no reason to create a new file
3243 with the same lifetime as the original file.
3246 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3247 module base addresses. This will help shooting seg faults
3248 in the field. [William Rowe <wrowe@lnd.com>]
3250 *) Update Apache on Windows documentation. Add new document
3251 describing how to compile Apache on Windows.
3252 [William Rowe <wrowe@lnd.com>]
3254 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3255 microseconds instead of seconds. Some storage leaks and other
3256 minor bugs in related code were fixed. [Jeff Trawick]
3258 *) Win32: First cut at getting mod_isapi working under 2.0
3259 [William Rowe <wrowe@lnd.com>]
3261 *) First stab at getting mod_auth_digest working under 2.0
3262 quick change summary:
3263 - moved the random byte generation (ap_generate_random_bytes) into APR
3264 - now uses ap_time_t
3265 - compiles and runs on linux
3267 [Brian Martin <bmartin@penguincomputing.com>]
3269 *) Win32: Move the space stripping of physical service names
3270 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3271 unresolved symbol. Add dependency checking to the
3272 CreateService call to ensure TCPIP and AFP (winsock) is started
3274 [William Rowe <wrowe@lnd.com>]
3276 *) Win32: Add code to perform latebinding on functions that may
3277 not exist on all levels of Windows where Apache runs. This
3278 is needed to allow Apache to start-up on Win95/98. All calls
3279 to non portable functions should be protected with
3280 ap_oslevel checks to prevent runtime segfaults.
3281 [William Rowe <wrowe@lnd.com>]
3283 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3285 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3287 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3288 This addresses PR 1623. Still need to address timing out runaway
3289 CGI scripts. [Bill Stoddard]
3291 *) Win32: Make ap_stat Windows 95/98 friendly
3292 [William Rowe <wrowe@lnd.com>]
3294 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3295 always fail. Need to initialise the dwOSVersionInfoSize member of the
3296 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3299 The patch also enhances ap_get_oslevel (and the associated enum) to
3300 handle selected service packs for NT4, and adds recognition for
3301 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3302 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3303 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3305 *) Get mod_rewrite building and running, and mod_status building for Win NT
3306 [Allan Edwards <ake@raleigh.ibm.com>]
3308 *) Patch to port mod_auth_db to the 2.0 api and also to support
3309 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3310 2.7.7. It should work with version 1 as well but I haven't tested it.
3311 [Brian Martin <bmartin@penguincomputing.com>]
3313 *) Get APR DSO code working under Windows. Includes cross platform
3315 [Tim.Costello@BTFinancialgroup.com]
3317 *) Fix some of the Windows APR time functions.
3320 *) FAQ changes related to tidying up historical documents on the web site.
3321 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3323 *) Move Windows DSO code into APR.
3326 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3327 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3328 at build time. At this point, the server will not compile on Windows because
3329 of the recent DSO commits. Fixing those next.
3330 [Bill Rowe & Bill Stoddard]
3332 *) Added error checking for file I/O APR routines.
3333 [Jon Travis <jtravis@covalent.net>]
3335 *) APR: Don't use the values of resolver error codes for the
3336 corresponding APR error codes. On Unix and Win32, return the
3337 proper APR error code after a resolver error. [Jeff Trawick]
3339 Changes with Apache 2.0a2
3341 *) Renamed the executable back to httpd on all platforms other
3345 *) Allow BeOS to survive restarts, log properly and a few
3346 small things it had problems with due to the way it setup
3347 users and groups. [David Reid]
3349 *) Get mod_rewrite working with APR locks
3350 [Paul Reder <rederpj@raleigh.ibm.com>]
3352 *) Actually remove the sempahore when the lock cleanup routine
3353 is called on BeOS. [David Reid]
3355 *) Clear hook registrations between reads of the config file.
3356 When DSOs are unloaded and re-loaded the old hook pointers may
3357 no longer be valid. This fix eliminates potential segfaults.
3358 [Allan Edwards <ake@raleigh.ibm.com>]
3360 *) Fix a problem with Sigfunc not being defined or bypassed
3361 if sigaction() wasn't found. [Jim Jagielski]
3363 *) Fix the locking mechanism on BSD variants. They now use fcntl
3364 locks. This allows the server to start and serve pages.
3367 *) First cut at getting the Win32 installer to work
3368 [William Rowe <wrowe@lnd.com>]
3370 *) Get htpasswd compiling under Windows
3371 [William Rowe <wrowe@lnd.com>]
3373 *) Change the log message for a bind() failure to show the
3374 interface and port number. [Jeff Trawick]
3376 *) Import the documentation from 1.3.12 and bring parts of it
3377 up-to-date with respect to the changes that have occurred
3381 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3382 now logged correctly on BeOS.
3385 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3386 Makefile.win includes the same user interface as the old
3388 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3390 *) Win32 exec now uses COMSPEC environment string for command
3391 shell path resolution.
3392 [William Rowe <wrowe@lnd.com>] PR#3715
3394 *) Win32: ap_connect() was not returning correct error condition
3396 [Allen Prescott <allen@clanprescott.com>]
3398 *) Win32: ap_open() was broken on Win9x because an NT-specific
3399 flag was passed to CreateFile. ap_puts() added an unnecessary
3401 [Jeff Trawick <trawick@us.ibm.com>]
3403 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3404 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3405 confusing ee/et name and made all extensions language/dialect
3406 rather than country reflecting. Changed example files to
3407 explicit reflect the ISO charset and added a few common
3408 ones to the example config [dirkx]
3410 *) Extend external module capability. To use this, you call
3411 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3414 *) Backported the various "default charset" fixes from 1.3.12,
3415 including the AddDefaultCharset directive. [Jim Jagielski]
3417 *) Added the capability to do ${ENVVAR} constructs in the
3418 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3419 it does this on a line by line basis; i.e. if the envvar
3420 expands to something with spaces you have to protect it
3421 by adding quotes around it (Unless of course you expect it
3422 to contains more than one argument. Alternatively you
3423 can compile it on a per token basis; which is what people
3424 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3425 hampers fancier hacks.
3426 [Dirk-Willem van Gulik]
3428 *) Changed the 'ErrorDocument' syntax in that it NO longer
3429 supports the asymetric
3431 ErrorDocument 301 "Some message
3433 Note the opening " quote, without a closing quote. It now
3434 has either the following syntaxes
3436 ErrorDocument XXX /local/uri
3437 ErrorDocument XXX http://valid/url
3438 ErrorDocument XXX "Some Message"
3440 The recognition heuristic is: if it has a space it
3441 is a message. If it has no spaces and starts with a /
3442 or is a valid URL then treat it that way. Otherwise it
3443 is assumed to be a message.
3445 This breaks backward compatibility but makes live a hell
3446 of a lot easier for GUI's and config file parsers.
3447 [Dirk-Willem van Gulik]
3449 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3450 syntax into a 'on' or 'off' syntax. As it currently is the
3451 only non nesting token which uses NO_ARGS and thus is an
3452 absolute pain for any config interface automation. This
3453 breaks backward compatibility. [Dirk-Willem van Gulik]
3455 *) Add ability to add external modules to the build process. This is
3456 done with --with-module=/path/to/module. Modules can only be added
3457 as static modules at this point.
3460 Changes with Apache 2.0a1
3462 *) Fix FreeBSD 3.3 core dump.
3463 Basically, ap_initialize() needs to get called before
3464 create_process(), since create_process() passes op_on structure
3465 to semop() to get a lock, but op_on isn't initialized until
3466 ap_initialize() calls setup_lock(). Here is a slight
3467 rearrangement to main() which calls ap_initialize() earlier...
3468 [Jeff Trawick <trawick@us.ibm.com>]
3470 *) Enable Apache to use sendfile/TransmitFile API
3471 [Bill Stoddard, David Reid, Paul Reder]
3473 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3477 *) Make file I/O and network I/O writev/sendv APIs consistent.
3478 Eliminate use of ap_iovec_t and use Posix struct iovec.
3479 Use seperate variable on ap_writev to set the number of iovecs
3480 passed in and number of bytes written.
3483 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3484 with ap_create_file_iol(). ap_create_file_iol() requires that
3485 the file be opened prior to the call using ap_open().
3488 *) Port mod_include and mod_cgi to 2.0
3489 [Paul Reder, Bill Stoddard]
3491 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3492 bytes_read/bytes_written is always valid (never -1). Plus
3493 some fixes to buff.c to correct problems introduced by the
3494 errno => ap_status_t changes a while back. Plus a fix to
3495 chunked encoding introduced right at the beginning of 2.0.
3498 *) Revamped UNIX build system to use autoconf and libtool.
3499 [Manoj Kasichainula, Sascha Schumann]
3501 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3503 *) More rigorous checking of Host: headers to fix security problems
3504 with mass name-based virtual hosting (whether using mod_rewrite
3505 or mod_vhost_alias).
3506 [Ben Hyde, Tony Finch]
3508 *) Add back support for UseCanonicalName in <Directory> containers.
3509 [Manoj Kasichainula]
3511 *) Added APLOG_STARTUP log type. This allows us to write an error
3512 message without any of the date and time information. As a part
3513 of this change, I also removed all of the calls to fprintf(stderr
3514 and replaced them with calls to ap_log_error using APLOG_STARTUP
3515 writing to stderr is no longer portable, because we don't direct
3516 stderr to the error log on all platforms.
3519 *) Convert error logging functions to take errno as an argument.
3520 This makes our error logs more portable, because some Windows API's
3521 don't set errno. This change allows us to still output a valid
3522 message on all of our platforms.
3525 *) mod_mime_magic runs in 2.0-dev now.
3526 [Paul Reder <rederpj@raleigh.ibm.com>]
3528 *) sendfile has been added to APR.
3529 [John Zedlewski <zedlwski@Princeton.EDU>]
3531 *) buff.c has been converted to no longer use errno.
3532 [Manoj Kasichainula]
3534 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3535 interface adaption to APR functions did it. [Martin Kraemer]
3537 *) Support DSOs properly on 32-bit HP-UX 11.0
3538 [Dilip Khandekar <dilip@cup.hp.com>]
3540 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3541 [Ralf S. Engelschall]
3543 *) Cleaned APR build environment integration and bootstrap APR
3544 automatically for developers from src/Configure.
3545 [Ralf S. Engelschall]
3547 *) Fixed building of src/support/htpasswd.c
3548 [Ralf S. Engelschall]
3550 *) When generating the Location: header, mod_speling forgot
3551 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3554 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3556 *) Change all pools to APR contexts. This is the first step to
3557 incorporating APR into Apache. [Ryan Bloom]
3559 *) Move "handler not found" warning message to below the check
3560 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3561 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3563 *) Support line-continuation feature in config.option file and
3564 allow the loading of multiple option sections at once via
3565 ``--with-option=<section1>,<section2>,...''
3566 [Ralf S. Engelschall]
3568 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3570 Changes with Apache MPM
3572 *) Use asynchronous AcceptEx() and a completion port to accept and
3573 dispatch connections to threads in Windows NT/2000.
3576 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3579 *) Implement the APACI --with-option facility
3580 (per default used the config.option file).
3581 [Ralf S. Engelschall]
3583 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3585 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3586 Replace pre_connection module call with a register_hook call and
3587 implement pre_connection as a hook. The intent is that these hooks will
3588 be extended to allow Apache to be multi-protocol, and also to allow the
3589 calling order to be specified on a per-hook/per-module basis.
3592 *) Implement mpm_* methods as "modules". Each method gets its own
3593 subdir in src/modules (eg: src/modules/prefork). Selection
3594 of method uses Rule MPM_METHOD. [Jim Jagielski]
3596 *) Port the hybrid server from the apache-apr repository as
3597 mpm_mpmt_pthread. [Manoj Kasichainula]
3599 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3600 amongst the unix MPMs.
3602 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3603 signal handling for the new world order. [Dean Gaudet]
3605 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3606 of alloc.c for now. [Dean Gaudet]
3608 *) Handle partial large writes correctly. [Ben Laurie]
3610 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3611 based on IP/port. [Ben Laurie]
3613 *) Port a bunch of modules to the new module structure.
3614 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3616 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3618 *) Basic restructuring to introduce the MPM concept; includes various
3619 changes to the module API... better described by
3620 docs/initial_blurb.txt. [Dean Gaudet]
3622 Changes with Apache pthreads
3624 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3625 buff operations (generally over a network).
3626 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3628 *) Created http_accept abstraction. Added 4 new functions (not exported):
3629 init_accept(), begin_accepting_requests(), get_request(),
3630 stop_accepting_requests() [Bill Stoddard]
3632 *) Fix to ap_rprintf call that allows mod_info to work properly.
3633 [James Morris <jmorris@intercode.com.au>]
3635 *) user and ap_auth_type fields were moved from connection_rec to
3636 request_rec. [Ryan Bloom]
3638 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3639 needed in a threaded server.
3641 *) Initial pthread implementation from from Dean's apache-nspr code.
3642 [Bill Stoddard, Ryan Bloom]
3645 Changes with Apache 1.3.9
3647 *) Remove bogus error message when a redirect doesn't set Location.
3648 Instead, use an empty string to avoid coredump if the error message
3649 was supposed to include a location. [Roy Fielding]
3651 *) Don't allow configure to include mod_auth_digest unless it is
3652 explicitly requested, even if the user asked for all modules.
3655 *) Translate module names to dll names for OS/2 so that they are no more
3656 than 8 characters long and have an extension of "dll" instead of "so".
3659 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3660 Fix test-compile check to check for randbyte instead of trand32.
3661 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3662 and tweak to make Amaya happier. [Ronald Tschalär]
3664 *) Ensure that the installed expat include files are world readable,
3665 just like the other header files. [Martin Kraemer]
3667 *) Fixed generated AddModule adjustments in APACI's `configure' script
3668 in order to allow (new) modules like mod_vhost_alias to be handled
3669 correctly (which was touched by the adjustments for mod_alias).
3670 [Ralf S. Engelschall]
3672 *) For binary builds, add -R flag to apachectl to work around the lack of
3673 an absolute path to the ./libexec directory where the libhttp.ep file
3674 is needed for SHARED_CORE architectures. [Randy Terbush]
3676 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3677 problem observed by some Win95/98 users where they get CGI script
3678 output sent to the console. [Bill Stoddard]
3680 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3681 routines are now called ap_base64* and are 'plain' (i.e., no
3682 pool access or anything clever). Inside util.c the routines acting
3683 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3684 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3685 now but deprecated. [dirkx]
3687 *) Clean up the base64 and SHA1 additions and make sure they are
3688 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3689 files. [Roy Fielding]
3691 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3692 checking. Allow compiling on VS 6.0. [Randy Terbush]
3694 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3696 *) Use TestCompile to search for the truerand library (rather than blindly
3697 assuming its existence). If it is not found, complain (but do not
3698 exit - yet). [Martin Kraemer]
3700 *) We forgot to add the new exported function names to
3701 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3703 *) Add description of -T command-line option to usage().
3704 [Ralf S. Engelschall]
3706 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3707 searched only AFTER libap has been searched, because libap needs
3708 some symbols from libos. [Martin Kraemer]
3710 *) Fix conflict with original mod_digest related to the symbol of the
3711 module dispatch list (which has to be unique for DSO and follow the
3712 usual conventions for the installation procedure).
3713 [Ralf S. Engelschall]
3715 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3716 for other platforms as well. [Martin Kraemer]
3718 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3719 types by AP_LONG and replace reference to renamed variable 'ubuf'
3720 by 'buffer'. [Martin Kraemer]
3722 Changes with Apache 1.3.8 [not released]
3724 *) Flush the output buffer immediately after sending an error or redirect
3725 response, since the result may be needed by the client to abort a
3726 long data transfer or restart a series of pipelined requests.
3727 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3729 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3730 [Ian Turner <iant@sequent.com>] PR#4735
3732 *) Local struct mmap in http_core.c conflicted with system structure
3733 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3735 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3736 [Ronald Tschalär <ronald@innovation.ch>]
3738 *) Fix a memory leak where the module counts were getting messed
3739 up across restarts. [David Harris <dharris@drh.net>]
3741 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3742 properly in mod_access.
3743 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3745 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3746 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3748 *) PORT: Support for compaq/tandem/com.
3749 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3751 *) Added SHA1 password encryption support to easy migration from
3752 Netscape servers. See support/SHA1 for more information.
3753 Caused the separation of ap_md5.c into md5, sha1 and a general
3754 ap_checkpass.c with just a validate_passwd routine. Added a
3755 couple of flags to support/htpasswd. Some reuse of the to64()
3756 function; hence renamed to ap_to64().
3757 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3759 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3760 with ASCII/EBCDIC conversions in "ident" query.
3761 [David McCreedy <McCreedy@us.ibm.com>]
3763 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3764 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3765 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3767 *) Fix SIGSEGV on some systems because the Vary fix below included
3768 a call to table_do with a variable argument list that was not
3769 NULL terminated. Replaced with better implementation. [Roy Fielding]
3771 Changes with Apache 1.3.7 [not released]
3773 *) The "Vary" response header field is now sanitised right before
3774 the header is sent back to the client. Multiple "Vary" fields
3775 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3776 "Vary: host, negotiate, host, accept-language") are reduced to
3777 single instances. This is a better solution than the force-no-vary
3778 one (which is still valid for clients that can't cope with Vary
3779 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3781 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3783 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3784 least on Linux and FreeBSD for now.
3787 *) Win32: More apache -k restart work. Restarts are now honored
3788 immediately and connections in the listen queue are -not- lost.
3789 This is made possible by the use of the WSADuplicateSocket()
3790 call. The listeners are opened in the parent, duplicated, then
3791 the duplicates are passed to the child. The original listen sockets
3792 are not closed by the parent across a restart, thus the listen queue
3794 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3796 *) Fix handling of case when a client has sent "Expect: 100-continue"
3797 and we are going to respond with an error, but get stuck waiting to
3798 discard the body in the pointless hope of preserving the connection.
3799 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3801 *) Fix 'configure' to work correctly with SysV-based versions of
3802 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3804 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3805 built-in values. Add "-e" option which works like -i but doesn't
3806 install the DSO; useful for editing httpd.conf with apxs. Fix
3807 editing code so that multiple invocations of apxs -a will not
3808 create duplicate LoadModule/AddModule entries; apxs can now be
3809 used to re- enable/disable a module. [Wilfredo Sanchez]
3811 *) Win32: Update the server to use Winsock 2. Specifically, link with
3812 ws2_32.lib rather than wsock32.lib. This gives us access to
3813 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3814 Win 95 users may need to update their TCP/IP stack to pick up
3815 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3816 [Bill Stoddard stoddard@raleigh.ibm.com]
3818 *) Win32: Redirect CGI script stderr (script debug info) into the
3819 error.log when CGI scripts fail. This makes Apache on Win32
3820 behave more like Unix.
3821 [Bill Stoddard stoddard@raleigh.ibm.com]
3823 *) Fixed `httpd' usage display: -D was missing.
3824 [Ralf S. Engelschall] PR#4614
3826 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3827 [Ralf S. Engelschall] PR#4561, PR#4562
3829 *) OS/2: Fix problem with accept lock semaphores where server would die with
3830 "OS2SEM: Error 105 getting accept lock. Exiting!"
3831 [Brian Havard] PR#4505
3833 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3834 [Randy Terbush <randy@covalent.net>]
3836 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3837 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3839 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3840 command potentially _is_ GCC. [Ralf S. Engelschall]
3842 *) Fix apxs build issues on AIX
3843 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3845 *) DocumentRoot Checking: Under previous versions, when Apache
3846 first started up, it used to do a stat of each DocumentRoot to
3847 see if it existed and was a directory. If not, then an error
3848 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3849 does not exist, you will get error messages in error_log. If
3850 the '-t' command line option is used (to check the configuration)
3851 the check of DocumentRoot IS performed. An additional command
3852 line option, '-T', has been added if you want to avoid the
3853 DocumentRoot check even when checking the configuration.
3856 *) Win32: The query switch "apache -S" didn't exit after showing the
3857 vhost settings. That was inconsistent with the other query functions.
3858 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3860 *) Win32: Changed behaviour of apache -k restart.
3861 Previously, the server would drain all connections in the stack's
3862 listen queue before honoring the restart. On a busy server, this
3863 could take hours. Now, a restart is honored almost immediately.
3864 All connections in Apache's queues are handled but connections in
3865 the stack's listen queue are discarded. Restart triggered by
3866 MaxRequestPerChild is unchanged.
3867 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3869 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3870 the accept loop. Good for a 5% performance boost. Cleaned up
3871 parent/child process management code.
3872 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3874 *) Added ceiling on file size for memory mapped files.
3875 [John Giannandrea <jg@meer.net>] PR#4122
3877 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3878 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3879 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3881 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3882 use this at least for Expat. [Ralf S. Engelschall]
3884 *) Allow .module files to specify libraries with Lib:.
3887 *) Allow SetEnvIf[NoCase] to test environment variables as well
3888 as header fields and request attributes. [Ken Coar]
3890 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3891 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3893 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3894 never accepted into any standard, and it opens up certain DoS
3895 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3897 *) TestCompile updated. We can now run programs and output the
3898 results during the Configure process. [ Jim Jagielski]
3900 *) The source is now quad (long long) aware as needed. Specifically,
3901 the Configure process determines the correct size of off_t and
3902 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3903 provides for the 'q' format qualifier (if quads are not available,
3904 'q' is silently "demoted" to long). [Jim Jagielski]
3906 *) When the username or password fed to htpasswd is too long, include the
3907 size limit in the error message. Also report illegal characters
3908 (currently only ':') in the username. Add the size restrictions
3909 to the man page. [Ken Coar]
3911 *) Fixed the configure --without-support option so it doesn't result in
3912 an infinite loop. [Marc Slemko]
3914 *) Piped error logs could cause a segfault if an error occured
3915 during configuration after a restart.
3916 [Aidan Cully <aidan@panix.com>] PR#4456
3918 *) If a "Location" field was stored in r->err_headers_out rather
3919 than r->headers_out, redirect processing wouldn't find it and
3920 the server would core dump on ap_escape_html(NULL). Check both
3921 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3922 if Location isn't set. [Doug MacEachern, Ken Coar]
3924 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3925 of the Expat 1.0.2 distribution. [Greg Stein]
3927 *) Replace regexec() calls with calls to a new API stub function
3928 ap_regexec(). This solves problems with DSO modules which use the regex
3929 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3931 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3932 environment variables can be set according to the protocol version
3933 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3935 *) Add DSO support for OpenStep (Mach 4.2) platform.
3936 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3938 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3939 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3941 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3942 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3944 *) Better DSO flags recognition on NetBSD platforms using ELF.
3945 [Todd Vierling <tv@pobox.com>] PR#4310
3947 *) Always log months in english format for %t in mod_log_config.
3948 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3950 *) Support for server-parsed and multiview-determined ReadmeName and
3951 HeaderName files in mod_autoindex. Removed the restriction on
3952 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3953 routines will deal with the access issues. (It's now possible to
3954 have {site|group|project|customer|...} wide readmes and headers.)
3955 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3958 *) When stat() fails, don't assume anything about the contents of
3959 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3961 *) It's OK for a semop to return EINTR, just loop around and try
3962 again. [Dean Gaudet]
3964 *) Fix configuration engine re-entrant hangups, which solve a
3965 handful of problems seen with mod_perl <Perl> configuration sections
3966 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3968 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3969 by default when building with APACI; allow for platform-specific
3970 variable defaults in configure. [Wilfredo Sanchez]
3972 *) Do setgid() before initgroups() in http_main; some platforms
3973 zap the grouplist when setgid() is called. This was fixed in
3974 suexec earlier, but the main httpd code missed the change.

3990 being newer than Configuration so that it is less likely to fail
3991 when using APACI and shadow sources. [Wilfredo Sanchez]
3993 *) PORT: Add initial support for Mac OS (versions 10.0 and
3994 greater). Use Mac OS X Server layout for now. Clean up dyld code
3995 in unix/os.c, and don't install the dyld error handlers, which
3996 are no longer needed in Mac OS. [Wilfredo Sanchez]
3998 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3999 locations to appropriate ones for user-built (as opposed to
4000 system) installs. [Wilfredo Sanchez]
4002 *) Modify mod_autoindex's handling of AddDescription so that the
4003 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
4005 *) Add functionality to the install-bindist.sh script created by
4006 binbuild.sh to use tar when copying distribution files to the
4007 serverroot. This allows upgrading an existing installation
4008 without nesting the new distribution in the old.
4010 install-bindist.sh now detects the local perl5 path to install
4011 apxs and dbmmanage with proper path to perl interpreter.
4013 Add an install-binsupport target which copies the source files
4014 for apxs and dbmmanage to bindist to allow these scripts to
4015 be properly installed relative to the destination serverroot.

4132 htpasswd utility was limiting passwords to only 8 characters.
4135 *) EBCDIC platforms: David submitted patches for two bugs in the
4136 MD5 digest port for EBCDIC machines:
4137 a) the htdigest utility overwrote the old contents of the digest file
4138 b) the Content-MD5 header value (ContentDigest directive) was wrong
4139 when the returned file was not converted from EBCDIC, but was a
4140 binary (e.g., image file) in the first place.

4182 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4183 a roughly 5 fold speed up. [Brian Havard]
4185 *) proxy ftp: instead of using the hardwired string "text/plain" as
4186 a fallback type for files served by the ftp proxy, use the
4187 ap_default_type() function to determine the configured type.
4188 This allows for special configurations like
4189 <Directory proxy:ftp://some.host>
4190 DefaultType gargle/blurb
4192 Additionally, add the Content-Encoding: header to FTP proxy replies
4193 when the encoding is defined (by the AddEncoding directive).
4194 Because it was missing, it was almost impossible to browse compressed
4195 files using the FTP proxy (works now perfectly in Communicator).
4196 The ftp proxy now also returns the Date: and Server: header lines (if not
4197 much else... This code is "somewhat" broken) like normal requests do.
4200 *) Be more smart in APACI's configure script when determining the UID/GID
4201 for User/Group directives and use the determined UID/GID to initialize
4202 the permissions on the proxycachedir.
4203 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4205 *) Changed the forking-prior-to-cleanup in the proxy module to first

4240 *) Added PassAllEnv; makes server's entire environment available
4241 to CGIs and SSIs executed within directive's scope. [Ken Coar]

4244 8 bit characters on a machine with signed char may produced

4246 work correctly on EBCDIC platforms.

4249 *) WIN32: Binary installer now runs the configuration DLL before
4250 the reboot prompt (which is only given if MSVCRT.DLL system

4276 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4277 for 8-bit safeness. [Dean Gaudet]
4279 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4280 because SPARCs have a small machine-specific maximum size for the Global
4281 Offset Table which is often exceeded when compiling one of the larger
4282 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4284 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

4311 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4314 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4315 to make platform installations easier. [Wilfredo Sanchez]
4317 *) In configure, do not append the target name to the directory path if
4318 the path already contains "apache". [Ralf S. Engelschall]
4320 *) SIGPIPE is now ignored by the server core. The request write routines
4321 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4322 correctly check for output errors and mark the connection as aborted.
4323 Replaced many direct (unchecked) calls to ap_b* routines with the
4324 analogous ap_r* calls. [Roy Fielding]
4326 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4327 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4328 Furthermore map lookups for non-existent keys are now cached as well.
4329 Additionally "txt" maps are now parsed with simple string functions
4330 instead of using ap_pregcomp(). As a side effect a bug that prevented
4331 the usage of keys containing the "," character was fixed.
4332 The changes drastically improve the performance when large rewrite maps
4334 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4336 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4337 other than GET, and const'd the definition of method in request_rec.

4342 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4343 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4345 *) Add %V to mod_log_config, this logs the hostname according to the
4346 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4347 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4349 *) Add support for \n and \t to mod_log_config, can be used to produce
4350 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4352 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4354 *) Added informative error messages for failed munmap() and fseek() calls
4355 in http_core.c. [John Bley, Roy Fielding]
4357 *) Added some informative error messages for some failed malloc()
4358 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4360 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4361 is removed. This allows <Directory proxy:*> directives to work and
4362 prevents invalid requests from killing the process.
4363 [Brian Havard <brianh@kheldar.apana.org.au>]

4369 David N. Welton: you can now have it generate an HTML TABLE, presumably
4370 for integration into other HTML sources. David updated the ab man page
4371 as well and added some missing descriptions. Thanks!
4372 [David N. Welton <davidw@prosa.it>]
4374 *) Win32: The filename validity checker now allows filenames containing
4375 characters in the range 0x80 to 0xff (for example accented characters).
4376 [Paul Sutton] PR#3890
4378 *) Added conditional logging based upon environment variables to
4379 mod_log_config. mod_log_referer and mod_log_agent
4380 are now deprecated. [Ken Coar]
4382 *) Allow apache acting as a proxy server to relay the real
4383 reason of a failure to a client rather than the "internal
4384 server error" it does currently. The general exposure mechanism
4385 can be triggered by any module by setting the "verbose-error-to"
4386 note to "*"; this allows more than just proxy errors to be exposed.
4387 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4389 *) Moved man pages for ab and apachectrl to section 8.
4390 [Wilfredo Sanchez, Roy Fielding]
4392 *) Added -S option to install.sh so that options can be passed to
4393 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4395 *) Tweak modules Makefile generated by Configure so that it handles
4396 the test case of no modules being selected. [chaz@reliant.com]
4398 *) Added a <LimitExcept method ...> sectioning directive that allows
4399 the user to assign authentication control to any HTTP method that
4400 is *not* given in the argument list; i.e., the logical negation
4401 of the <Limit> directive. This is particularly useful for controlling
4402 access on methods unknown to the Apache core, but perhaps known by
4403 some module or CGI script. [Roy Fielding, Tony Finch]
4405 *) Prevent apachectl from complaining if the PIDFILE exists but
4406 does not contain a process id, as might occur if the server is
4407 being rapidly restarted. [Wilfredo Sanchez]
4409 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4411 *) Entity tag comparisons for If-Match and If-None-Match were not being
4412 performed correctly -- weak tags might cause false positives. Also,
4413 strong comparison wasn't properly enforced in all cases.
4414 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4416 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4419 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4420 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4422 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4423 to util.c for parsing an HTTP header field value to extract the next
4424 list item, taking into account the possible presence of nested comments,
4425 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4426 insignificant whitespace and lowercases non-quoted tokens.
4427 [Roy Fielding] PR#2065
4429 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4430 code different from 500. This allows the proxy to, e.g., return
4431 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4433 *) Fix ordering of language variants for the case where the traditional
4434 negotiation algorithm is being used with multiple language variants
4435 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4437 *) Do not round the TCN quality calculation to 5 decimal places,
4438 unlike RFC 2296, because the calculation might need 12 decimal places
4439 to get the right result. [Roy Fielding]
4441 *) Remove unused code to disable transparent negotiation when
4442 negotiating on encoding only, as we now handle encoding too
4443 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4444 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4445 some debugging statements within mod_negotiation. [Koen Holtman]
4447 *) Fixed a rare memory corruption possibility in mod_dir if the index
4448 file is negotiable and no acceptable variant can be found.
4449 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4451 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4452 searching the Win32 registry for script interpreters.
4455 *) Win32: The compiled-in default filename for the error log is now
4456 error.log, which matches the default in the distributed httpd.conf.
4459 *) Win32: Any error messages from -i or -u command line options are now
4460 displayed on the console output rather than sent to the error log.
4461 Also the "Running Apache..." message is not output unless Apache is
4462 going to serve requests. [Paul Sutton]
4464 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4465 and use a private significator ('$apr1$') to mark passwords as
4466 being smashed with our own algorithm. Also abstract the password
4467 checking into a new ap_validate_password() routine. [Ken Coar]
4469 *) Win32: The filename validity checker now allows "COM" but refuses
4470 access to "COM1" through "COM4". This allows filenames such
4471 as "com.name" to be served. [Paul Sutton] PR#3769.
4473 *) BS2000: Adapt to the new ufork() system call interface which will
4474 make subtasking easier on the OSD/POSIX mainframe environment.
4477 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to

4480 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4481 use `.db' instead of `.pag' not only for FreeBSD, but also when
4482 the NDBM library looks like Berkeley-DB based.

4500 [Jim Jagielski] PR#3671
4502 *) A consistent and conservative style for all shell scripts has been
4503 implemented. Basically, all shell string tests use the traditional
4504 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4505 to protect against bare null variable strings (ie: wrapping both
4506 sides with double quotes and prepending 'x'). 'x' was chosen
4507 because it's more universal and hopefully easier for old shell
4508 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4511 *) The status module now prints out both the main server generation as
4512 well as the generation of each process. Also, the vhost info is
4513 printed with '?notable'. [Jim Jagielski]
4515 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4516 and this makes its functions available to things in src/support.
4519 Changes with Apache 1.3.4
4521 *) Renamed macros status_drops_connection to ap_status_drops_connection
4522 and vestigial scan_script_header to ap_scan_script_header_err,
4523 mostly for aesthetic reasons. [Roy Fielding]
4525 *) The query switch "httpd -S" didn't exit after showing the
4526 vhost settings. That was inconsistent with the other query functions.
4529 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4530 filename to the end of the STANDARD_MODULE_STUFF. Its
4531 presence at the beginning prevented reporting of the filename
4532 for modules compiled before 1 January 1999. [Ken Coar]
4534 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4535 to detect and prevent access to special DOS device file names.
4536 [Paul Sutton, Ken Parzygnat]
4538 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4539 and Makefile_win32_debug.txt (debug build) that work on Win95.
4540 Run each of the following from the src directory:
4541 nmake /f Makefile_win32.txt # compiles normal build
4542 nmake /f Makefile_win32.txt install # compiles and installs
4543 nmake /f Makefile_win32.txt clean # removes compiled junk
4544 nmake /f Makefile_win32_debug.txt # compiles debug build
4545 nmake /f Makefile_win32_debug.txt install
4546 nmake /f Makefile_win32_debug.txt clean
4549 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4550 to build binary distributions. [Lars Eilebrecht]
4552 *) IndexOptions SuppressColumnSorting only turned off making
4553 the column headers anchors; you could still change the display
4554 order by manually adding a '?N=A' or similar query string to the
4555 URL. Now SuppressColumnSorting locks in the sort order so
4556 it can't be overridden this way. [Ken Coar]
4558 *) Added IndexOrderDefault directive to supply a default sort order
4559 for FancyIndexed directory listings. [Ken Coar] PR#1699
4561 *) Change the ap_assert macro to a variant that works on all platforms.
4562 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4564 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4565 search for an underscore on dlsym() (as it's already the case
4566 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4568 *) Small fix for mod_env.html: The module was documented as to be _not_
4569 compiled into Apache per default, although it _IS_ compiled into
4570 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4572 *) Instead of fixing a bug in the generation procedure for config.status (a
4573 backslash was missing) we remove the bug together with it's complete
4574 context because the special cases of the past can now no longer occur
4575 because of the recent magic for the --with-layout default.
4576 [Ralf S. Engelschall] PR#3590
4578 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4579 making sure the src/support/ tools are _forced_ to be build last (they
4580 depend on other libraries).
4581 [Markus Theissinger <markus.theissinger@gmx.de>]
4583 *) Fix installation procedure: Now that os-inline.c is actually used (a
4584 recently fixed bug prevented this) we need to also install os-include.c
4585 in addition to os.h into the PREFIX/include/ location or building of
4586 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4588 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4589 allow us to distinguish between a garbled DSO (or even a file which isn't
4590 an Apache module DSO at all) and a DSO which doesn't match the current
4591 Apache API. [Ralf S. Engelschall] PR#3152
4593 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4594 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4595 match case insensitive (this especially avoids nasty patterns like
4596 `[tT][eE][sS][tT]'). Second two additional internal map functions
4597 `escape' and `unescape' were added which can be used to escape/unescape
4598 to/from hex-encodings in URLs parts (this is especially useful in
4599 combination with map lookups).
4600 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4602 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4603 forgotten (because it was a macro) in the symbol renaming process.
4604 [Ralf S. Engelschall]
4606 *) Fix some inconsistencies related to the scopes of directives. The only
4607 user visible change is that the directives `UseCanonicalName' and
4608 `ContentDigest' now use the (more correct) `Options' scope instead of
4609 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4611 *) Using DSO, the Server token was being mangled. Specifically, the
4612 module's token was being added first before the Apache token. This
4613 has been fixed. [Jim Jagielski]
4615 *) Major overhaul of mod_negotiation.c, part 2.
4616 - properly handle "identity" within Accept-Encoding.
4617 - allow encoded variants in RVSA negotiation and let them appear in
4618 the Alternates field using the non-standard "encoding" tag-list.
4619 - fixed both negotiation algorithms so that an explicitly accepted
4620 encoding is preferred over no encoding if "identity" is not
4621 included within Accept-Encoding.
4622 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4623 of large substring sequences.
4624 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4627 *) Major overhaul of mod_negotiation.c, part 1.
4628 - cleanups to mod_negotiation comments and code structure
4629 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4630 support for everything in the upcoming HTTP/1.1
4631 revision (draft-ietf-http-v11-spec-rev-06.txt).
4632 - language tag matching also handles tags with more than 2
4634 - empty Accept, Accept-Language, Accept-Charset headers are
4635 processed correctly; previously an empty header would make all
4636 values acceptable instead of unacceptable.
4637 - allowed for q values in Accept-Encoding
4638 - added support for transparent content negotiation (rfc2295 and
4639 rfc2296) (though we do not implement all features in these drafts,
4640 e.g. no feature negotiation). Removed old experimental version.
4641 - implemented 'structured entity tags' for better cache correctness
4642 (structured entity tags ensure that caches which can deal with Vary
4643 will (eventually) be updated if the set of variants on the server
4645 - this involved adding a vlist_validator element to request_rec
4646 - this involved adding the ap_make_etag() function to the global API
4647 - modified guessing of charsets used by Apache negotiation algorithm
4648 to guess 'no charset' if the variant is not a text/* type
4649 - added code to sort multiviews variants into a canonical order so that
4650 negotiation results are consistent across backup/restores and mirrors
4651 - removed possibility of a type map file resolving to another type map
4652 file as its best variant
4653 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4655 *) RFC2396 allows the syntax http://host:/path (with no port number)
4656 but the proxy disallowed it (ap_proxy_canon_netloc()).
4657 [David Kristol <dmk@bell-labs.com>] PR#3530
4659 *) When modules update/modify the file name in the configfile_t structure,
4660 syntax errors will report the updated name, not the original one.
4661 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
4663 *) Correct some filename case assumptions from WIN32 to
4664 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4666 *) For %v log ServerName regardless of the UseCanonicalName
4667 setting (similarly for %p). [Dean Gaudet]
4669 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4670 rather late (too late for some invocations of TestCompile).
4671 This improves the make environment available to TestCompile and
4672 the *.module scripts. [Martin Kraemer]
4674 *) The hashbang emulation code in ap_execve.c would interpret
4675 #!/hashbang/scripts correctly, but failed to fall back to a
4676 standard shell for scripts which did NOT start with #!
4677 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4679 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4682 *) Update APXS manual page: some -q option arguments were missing
4683 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4685 *) Cleanup the command line options: `-?' was documented to show
4686 the usage list but does it with an error because `?' is not a valid
4687 command. OTOH a lot of users expect `-h' to print such a usage list and
4688 instead are annoyed for ages by our huge unreadable list of directives.
4689 So we now changed the command line options this way:
4691 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4692 very similar to the popular linker option.
4694 Intent: while -l gives the small list of modules, -L now gives the
4695 large list of directives implemented by these modules. This is also
4696 consistent with -v (short version info) and -V (large version info).
4698 Intent: it's now the expected option ;-)
4699 The manual page was adjusted accordingly.
4700 [Ralf S. Engelschall] PR#2714
4702 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4703 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4705 *) Removed recently introduced bugs and disfigurements in APACI:
4706 o fixed argument line processing: using $args was broken: It was not
4707 initialized and using args="$args $apc_option" and even args="$args
4708 \"$apc_option\"" fails in the second processing round for any arguments
4709 containing whitespaces. The only correct way is to use the construct
4710 "$@" (but not possible here) or iterate _both_ times over the implicit
4711 argument line (no argument to for-loop) which is what we now use.
4712 o make --with-layout=Apache the default without creating
4713 redundancy (copying the --with-layout block in the argument parsing
4714 loop). We achieve this by using the "$@" construct together with the
4715 `set' command to prepend --with-layout=Apache to the command line in
4716 case --with-layout is not used.
4717 o fixed auto-suffix handling now that config.layout exists.
4718 Paths which are auto-suffixed are marked with a trailing plus sign in
4719 config.layout and every path now can be marked this way (not only the
4720 four paths for which we do it currently). Additionally the suffix is
4721 no longer a static one. Instead it's now `/<target>' where <target> is
4722 the argument of the --target option or per default `httpd'.
4723 o allow also tabs (and only spaces) where we match whitespaces
4724 o various fixes and cleanups related to used shell coding style
4725 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4726 o trimmed output of --help to fit into 80 columns
4727 [Ralf S. Engelschall]
4729 *) Added two new core API functions, ap_single_module_configure() and
4730 ap_single_module_init(), which are now used by mod_so to configure a module
4731 after loading. [Ralf S. Engelschall]
4733 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4734 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4735 of ap_config.h to allow serialized accept for multiport listens.
4736 [Roy Fielding, Curt Sampson] PR#3120
4738 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4739 of ap_config.h that would skip several defines if DEFAULT_GROUP
4740 was overridden. [Roy Fielding]
4742 *) PORT: The I86 version of DGUX has support for strncasecmp and
4743 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4745 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4746 defined before it might be used. [Victor Khimenko]
4748 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4749 [Tom Serkowski <tks@bsdi.com>] PR#3453
4751 *) Make generation of src/Configuration.apaci more robust: It failed to
4752 differenciate between modules when one module name was a postfix of
4753 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4754 just XXX (think about totally non-standard names like "apache_ssl", too).
4755 [Ralf S. Engelschall] PR#3380
4757 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4758 since 1.3b7) and make whitespace handling more robust (it failed horrible
4759 when whitespaces were present in the arguments of -D options).
4760 [Ralf S. Engelschall] PR#3240
4762 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4763 creates an external package shadow tree in DIR before the local build
4764 shadow tree is generated under DIR. This way one can have the extracted
4765 Apache distribution tree read-only on NFS or CDROM and still build Apache
4766 from these sources. An automatically triggered VPATH-like mechanism is
4767 provided through the TOP variable, too.
4768 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
4770 *) Fix negotiation so that a Vary response header is correctly
4771 generated when, for a particular dimension, variants only vary
4772 in having or not having a value for that dimension. [Paul Sutton]
4774 *) Fix negotiation so that we prefer an encoded variant over an
4775 unencoded variant if the user-agent explicitly says it can
4776 accept that encoding. Previously we always preferred the unencoded
4778 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4780 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4781 and the usage page was inconsistent with the functionality and manpage.
4782 [Ralf S. Engelschall]
4784 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4785 They can occur multiple times and their arguments (`xxx') are passed AS
4786 IS to the compiler/linker command. [Ralf S. Engelschall]
4788 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4789 procedure of mod_rewrite: very long keys were truncated.
4790 [Ralf S. Engelschall]
4792 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4793 identifier, currently "Apache" and "GNU" are pre-defined in the file
4794 config.layout. Custom layouts are possible by using FILE:ID as the
4795 argument where the layout ID is taken from FILE.
4797 The config.layout file consists of <Layout ID>..</Layout> sections
4798 where inside those sections "path_variable: path_value" pairs can be
4799 specified. These lines are converted to path_variable='path_value'.
4801 *) Add a DefaultLanguage directive so that files missing a language
4802 extension (e.g., .fr, .de) can be labelled as being some other
4803 default language. DefaultLanguage can appear in <Directory> and
4804 <Files> containers as well as .htaccess files. [Paul Sutton]
4807 *) Fix TARGET configuration when configuring and installing using
4808 APACI configure. TARGET now defines the basename of the configuration
4809 file, startup script, manual page, etc. log_error_core() now reports
4810 the server binary name given by argv[0]. TARGET can now also be defined
4811 with --target=TARGET parameter passed to APACI configure.
4812 [Ralf Engelschall, Randy Terbush]
4814 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4815 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
4817 *) ap_md5_binary() was using sprintf() rather than a table lookup
4818 to convert binary bytes to hex digits.

4834 notice to the error log. It is not possible to send a 401 response
4835 and a redirect at the same time. [Lars Eilebrecht]
4837 *) Fallback to native compilers for IRIX-32 platform. It seems that
4838 a gcc 2.8.1 compiled apache is logging client addresses with all
4839 bits set (255.255.255.255). This is the second such problem caused
4840 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4843 *) Updated mime.types to reflect current Internet media types
4844 and include a URL to the registry.

4918 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4919 in the Configuration[.apaci] file. Two special and important variants are
4920 supported for the option argument: first BEGIN:foo which permutes module
4921 mod_foo with the begin of the module list, i.e. it `moves' the module to
4922 the begin of the list (gives it lowest priority). And second foo:END
4923 which permutes mod_foo with the end of the module list, i.e. it `moves'
4924 the module to the end of the list (gives it highest priority).

4972 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
4974 *) Log an error if we encounter a malformed "require" directive
4975 in mod_auth if we know that we know that no other module can
4976 deal with it. [Marc Slemko]
4978 *) Remove ap_private_extern method of hiding conflicting symbols
4979 on the NEXT platform because it is not correct for all versions,
4980 and the versions for which it is correct are unknown.
4981 [Wilfredo Sanchez <wsanchez@apple.com>]
4983 *) Fix inheritance of IndexOptions NameWidth and remove unintended
4984 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
4986 *) Fix per-directory config merging for cases in which a 500 error
4987 is encountered in an .htaccess file somewhere down the tree.
4990 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
4992 *) Fixed a segmentation violation in mod_proxy when a response is
4993 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
4995 Changes with Apache 1.3.3
4997 *) Added a complete implementation of the Expect header field as
4998 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
4999 response when we already know the final status, which is mighty
5000 useful for PUT responses that result in 302 or 401. [Roy Fielding]
5002 *) Remove extra trailing whitespace from the getline results as part
5003 of the protocol processing, which is extra nice because it works
5004 between continuation lines, is almost no cost in the normal case
5005 of no extra whitespace, and saves memory. [Roy Fielding]
5007 *) Added new HTTP status codes and default response bodies from the
5008 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
5009 HTTP Extension Framework (510) specifications. Did not add the
5010 WebDAV 424 and 425 codes because they are bogus. We don't use any
5011 of these codes yet, but they are now available to 3rd-party modules.
5014 *) Fix a possible race condition between timed-out requests and the
5015 ap_bhalfduplex select that might result in an infinite loop on
5016 platforms that do not validate the descriptor. [Roy Fielding]
5018 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
5019 running Apache server [Paul Sutton]
5021 *) Fix mod_autoindex bug where directories got a size of "0k" instead
5022 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
5025 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
5027 *) Add the server signature text (from the core ServerSignature directive)
5028 to the list of envariables available to scripts, SSI, and the like.
5031 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
5032 [M. Laak <maert@proinv.ee>] PR#3108
5034 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
5035 calculation in mod_status for all systems which don't have POSIX
5036 sysconf() (like UTS 2.1) and not only for the NEXT platform.
5037 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
5039 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
5040 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
5041 instead of ap_getword(..., ' ') (which parses only according to spaces
5042 but not tabs). [James Morris <jmorris@intercode.com.au>,
5043 Ralf S. Engelschall] PR#3105
5045 *) Fix the SERVER_NAME variable under sub-request situations (where
5046 `UseCanonicalName off' is used) like CGI's called from SSI pages or
5047 RewriteCond variables by adopting r->hostname to sub-requests.

5061 *) PORT: Remove extra HAVE_SYS_RESOURCE_H define for RHAPSODY since
5062 it is now taken care of properly by the header file tests.
5063 [Wilfredo Sanchez <wsanchez@apple.com>]
5065 *) Fix problem with scripts and filehandle inheritance on Win32.
5066 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2884, 2910
5068 *) Win32 name canonicalisation could end up using the server's
5069 working directory to fill in some blanks. [Ken Parzygnat
5070 <kparz@raleigh.ibm.com>] PR#3001
5072 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
5073 absolute paths begin with "/" -- because they don't on Win32.
5074 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
5076 *) Add [REDIRECT_]VARIANTS environment variable to mod_speling
5077 so that ErrorDocument 300 processors can reformat the list
5078 if desired. [Ken Coar] PR#2859
5080 *) Add +/- incremental prefixes to IndexOptions keywords, and
5081 enable merging of multiple IndexOptions directives. [Ken Coar]
5083 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
5084 <steve.cameron@compaq.com>]
5086 *) Reconstructed the loop through multiple htaccess file names so
5087 that missing files are not confused with unreadable files.
5090 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
5091 errno on an error, which leads to one error being mistaken for
5092 another when reading non-existent .htaccess files.
5095 *) OS/2: The new header tests get things right, need to update
5096 ap_config.h. [Brian Havard]
5098 *) The Perl %ENV hash will now be setup by default when using the
5099 mod_include `perl' command [Doug MacEachern]
5101 *) PORT: Add Pyramid DC/OSx support to configuration mechanism.
5102 [Earle Ake <akee@wpdiss1.wpafb.af.mil>]
5104 *) PORT: Fix sys/resource.h handling for Amdahl's UTS 2.1

5107 *) Correct comment in mod_log_config.c about its internals.
5108 [Elf Sternberg <elf@halcyon.com>]
5110 *) Avoid possible line overflow in Configure: Use an awkfile to
5111 handle the creation of modules.c [Jim Jagielski]
5113 Changes with Apache 1.3.2
5115 *) Fix bug in ap_remove_module(), which caused problems for dso's
5116 who were the top_module. [Doug MacEachern]
5118 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
5119 mod_auth_db to both be friendly to users who wants to use this version
5120 and to avoid problems under platforms where only version 2.x is present.
5121 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
5123 *) When using ap_log_rerror(), make the error message available to the
5124 *ERROR_NOTES envariables by default. [Ken Coar]
5126 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
5127 You now must define a BS2000Account name for the server User.
5128 This has fewer security implications than the old approach.
5131 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
5132 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
5133 platform to make the braindead HPUX linker happy. Notice, for the module
5134 DSOs we don't have to use this, because these are loaded manually (and
5135 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
5137 *) Remove 64 thread limit on Win32.
5138 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5140 *) Remove redundant substitutions in top-level Makefile.tmpl.
5141 [Ralf S. Engelschall]
5143 *) Fix APACI's `Group' configuration adjustment - especially for Linux
5144 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
5146 *) Make PrintPath work generically instead of having one version
5147 strictly for OS/2. [Jim Jagielski, Brian Havard]
5149 *) Fix the recently introduced C header file checking: We now use the C
5150 pre-processor pass only (and no longer the complete compiler pass) to
5151 determine whether a C header file exists or not. Because only this way
5152 we're safe against inter-header dependencies (which caused horrible
5153 portability problems). The only drawback is that we now have a CPP
5154 configuration variable which has to be determined first (we do a similar
5155 approach as GNU Autoconf does here). When all fails the user still has
5156 the possibility to override it manually via APACI or src/Configuration.
5157 As a fallback for the header check itself we can directly check the
5158 existance of the file under /usr/include, too.
5159 [Ralf S. Engelschall] PR#2777
5161 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
5162 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
5163 ap_private_extern defined to hide symbols that conflict with loaded
5164 dynamic libraries on the NEXT and RHAPSODY platforms.
5165 [Wilfredo Sanchez <wsanchez@apple.com>]
5167 *) Delete PID file on clean shutdowns.
5168 [Charles Randall <crandall@matchlogic.com>] PR#2947
5170 *) Fix mod_auth_*.html documents: NSCA -> NCSA
5171 [Youichirou Koga <y-koga@jp.FreeBSD.org>] PR#2991

5176 *) Fix dbmmanage.1 manual page.
5177 [Youichirou Koga <y-koga@jp.FreeBSD.org>] PR#2992
5179 *) Fix possible buffer overflow situation in suexec.c.
5180 [Jeff Stewart <jws@purdue.edu>] PR#2790
5182 *) Add some more LIBS for the SCO5 platform which are needed for the already
5183 used -lprot. It's actually a bug in SCO5, of course.
5184 [Ronald Record <rr@sco.com>] PR#2533
5186 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
5187 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
5189 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
5190 platform, because it's only supported under version 4.0 and higher. But
5191 because our GuessOS is still unaware of Digital UNIX versions and the
5192 -msym is just to optimize the DSO statup time a little bit it's safe and
5193 best when we leave it out now. [Ralf S. Engelschall] PR#2969
5195 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
5196 functions: First all three functions no longer fail on strings containing
5197 "%" chars and second ap_log_printf() no longer does a double-formatting
5198 (instead it directly passes through the message to be formatted to the
5199 real internal formatting function). [Ralf S. Engelschall] PR#2941
5201 *) Allow "Include" directives anywhere in the server config
5202 files (but not .htaccess files). [Ken Coar] PR#2727
5204 *) The proxy was refusing to serve CONNECT requests except to
5205 port 443 (https://) and 563 (snews://). The new AllowCONNECT
5206 directive allows the configuration of the ports to which a
5207 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5209 *) mod_expires will now act on content that is not sent from a file
5210 on disk. Previously it would never add an Expires: header to
5211 any response that did not come from a file on disk; the only
5212 case where it still doesn't (and can't) add one for that type of
5213 content is if you are using a modification date based setting.
5214 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
5216 *) Problems encountered during .htaccess parsing or CGI execution
5217 that lead to a "500 Server Error" condition now provide explanatory
5218 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
5221 *) Add NameWidth keyword to IndexOptions directive so that the
5222 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
5225 *) Recognize lowercase _and_ uppercase `uname' results under
5226 SCO OpenServer. [David Coelho <drc@ppt.com>]
5228 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5229 a common problem of (mis-administrated?) IIS servers, make the apache
5230 proxy immune to these errors (and ignore the duplicates, but log
5231 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5233 *) The <IfModule and <IfDefine block starting directives now only
5234 allow exactly one argument. Previously, the optional negation
5235 character '!' could be separated by whitespace without a syntax
5236 error being reported, albeit defeating the IfModule functionality
5237 (enclosed directives would ALWAYS be executed). By using the
5238 stricter syntax, these hard-to-track errors can be avoided.
5241 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5242 cause the standalone FancyIndexing directive to logically OR
5243 into any existing IndexOptions settings rather than wiping
5244 them out. [Ken Coar]
5246 *) Changes in ftp proxy: make URL parsing simpler by using the
5248 + Add display of the "current directory" in cases where it's
5249 different from the supplied path (e.g., ftp://user@host/ lives
5250 in /home/user, not in /, therefore clicking on "../" in the
5251 starting directory might send us to /home/).
5252 + When ftp login fails, (esp. when a user name was part of the
5253 URL already), we now return [401 Unauthorized ] to allow the
5254 browser to pop up an authorization dialog. This makes passwords
5255 slightly less visible (they don't appear in the regular log files)
5256 and implements a functionality that other www proxy servers
5260 *) Triggered by the recent "Via:" header changes, the proxy module would
5261 dump core for replies with invalid headers (e.g., duplicate
5262 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5263 core dump is avoided. Also, broken replies are not cached.
5264 [Martin Kraemer] PR#2914
5266 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
5267 plop gmon.out profile data for each child [Doug MacEachern]
5269 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
5270 config.status script to be immune against arguments with whitespaces.
5271 [Yves Arrouye <yves@apple.com>] PR#2866
5273 *) Replace the inlined information grabbing stuff for the configuration
5274 adjustment feature (no --without-confadjust) with calls to a new helper
5275 script `buildinfo.sh' which is both more flexible and already proofed to
5276 be more robust against platform differences. This mainly fixes the
5277 recently occured ``sed: command garbled: ...'' problems.
5278 [Ralf S. Engelschall] PR#2776, PR#2848
5280 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
5281 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
5282 without complains after we recently added the POST feature.
5283 [Ralf S. Engelschall]
5285 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
5286 modules as API functions and we forgot them at the big symbol renaming.
5287 [Ralf S. Engelschall]
5289 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
5290 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895
5292 *) Dynamically size the filename column of mod_autoindex output.
5295 *) Add the ability to do POST requests to the ab benchmarking tool.
5296 [Kurt Sussman <kls@best.com>] PR#2871
5298 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5299 5 to 10 because there are some users out there who always have 5 to 8
5300 variables in one RewriteRule and had to patch mod_rewrite.h for every
5301 release. So 15 should be now more than enough, even for them. (I never
5302 needed more than 4 in my RewriteRules ;-)
5303 [Ralf S. Engelschall]
5305 *) Make the proxy generate and understand Via: headers
5308 *) Change the proxy to use tables instead of array_headers for
5309 the header lines. [Martin Kraemer]
5311 *) Make sure the config.status file is not overridden when just
5312 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
5314 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
5315 provide a way to trace API changes that add functionality but do
5316 not create a compatibility issue for precompiled modules, etc.
5317 See include/ap_mmn.h for more details. [Randy Terbush]
5319 *) Fix suexec installation under `make install root=xxx' situation.
5320 [Ralf S. Engelschall]
5322 *) Extend the output of the -V switch to include the paths of all
5323 compiled-in configuration files, if they were overridden at
5324 compile time, for least astonishment of the user.
5327 *) When READing a request in ExtendedStatus mode, the "old"
5328 vhost, request and client information is not displayed.
5331 *) STATUS is no longer available. Full status information now
5332 run-time configurable using the ExtendedStatus directive.
5335 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5336 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5337 a function which can be used to perform bulk update operations
5338 on tables in a more efficient manner. [Dean Gaudet]
5340 *) SECURITY: Added compile-time and configurable limits for
5341 various aspects of reading a client request to avoid some simple
5342 denial of service attacks, including limits on maximum request-line
5343 size (LimitRequestLine), number of header fields (LimitRequestFields),
5344 and size of any one header field (LimitRequestFieldsize). Also added
5345 a configurable directive LimitRequestBody for limiting the size of the
5346 request message body. [Roy Fielding]
5348 *) Make status module aware of DNS and logging states, even if
5349 STATUS not defined. [Jim Jagielski]
5351 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
5353 *) Enhance mod_speling so that CheckSpelling can be used in
5354 <Directory> containers and .htaccess files. [Ken Coar]
5356 *) API: new ap_custom_response() function for hooking into the
5357 ErrorDocument mechanism at runtime [Doug MacEachern]
5359 *) API: new ap_uuencode() function [Doug MacEachern]
5361 *) API: scan_script_header_err_core() now "public" and renamed
5362 ap_scan_script_header_err_core() [Doug MacEachern]
5364 *) The 'status' module will now show the process pid's and their
5365 state even without full STATUS accounting. [Jim Jagielski]
5367 *) Restore the client IP address to the error log messages, this
5368 was lost during the transition from 1.2 to 1.3. Add a new
5369 function ap_log_rerror() which takes a request_rec * and
5370 formats it appropriately. [Dean Gaudet] PR#2661
5372 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5373 whitespace in input lines -- including within quoted strings.
5375 but leading and trailing whitespace should continue to be
5376 stripped [Martin Kraemer]
5378 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5379 the ugly use of an env. variable and use command-line args for
5380 alternate $PATH. Make more like advanced 'type's as well.
5383 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
5384 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
5385 <alain.st-denis@ec.gc.ca>] PR#2736
5387 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
5389 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
5390 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
5391 directory was renamed to src/os/os2/ for consistency.
5392 [Brian Havard, Ralf S. Engelschall]
5394 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5395 files (here modules) against other DSO files (here shared libraries).
5396 This is done by determining a subset of LIBS which can be safely used for
5397 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5398 disabled for all platforms to avoid problems with this (experimental)
5399 rule. But we provide it now for those people how ran into problems and
5400 want to came out by forcing linking against DSOs.
5401 [Ralf S. Engelschall] PR#2587
5403 *) Fix suEXEC start message: Has to be of `notice' level to really get
5404 printed together with the standard startup message because the `notice'

5417 cause the client to miss the HTTP error response. [Roy Fielding]
5419 *) One more portability fix for APACI shadow tree support: Swap order of awk
5420 and sed in top-level configure script to avoid sed fails on some
5421 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the

5479 the read_request error conditions of URI-too-long (414) and
5480 malformed header fields (400). [Roy Fielding] PR#2646
5482 *) Add support for the Max-Forwards: header line required by RFC2068 for
5483 the TRACE method. This allows apache to TRACE along a chain of proxies

5526 *) Global renaming of C header files to both get rid of conflicts with third
5527 party packages and to again reach consistency:

5535 *) mod_mmap_static will no longer take action on requests unless at
5536 least one "mmapfile" directive is present in the configuration.
5537 This experimental module has to do some black magic to operate
5538 inside the current API and thus creates side-effects for other

5653 directory, bail out of the request with an error message. [W G Stoddard]
5655 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
5656 these are treated by Win32 as if they are ".." but are not detected by
5657 other machinery within Apache. This is something of a kludge but
5658 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5660 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5661 pools and thus pollutes libap (until the pool stuff is moved there).

5678 user. Package authors can use the --without-confadjust option to disable
5679 these configuration adjustments.

5688 as <IfModule>..</IfModule> sections) which can be used to skip or process
5689 contained commands dependend of ``-D PARAMETER'' options on the command
5690 line. This can be used to achieve logical conditions like <IfDefine
5691 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)

5693 modules via LoadModule, etc. [Ralf S. Engelschall]

5700 truncated which forced following HTTP headers to be data in the HTTP

5704 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5705 in top-level configure script to avoid sed fails on some platforms (for
5706 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5707 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5709 *) Improve performance of directory listings (mod_autoindex) by comparing
5710 integer keys (last-modified and size) as integers rather than converting
5711 them to strings first. Also use a set of explicit byte tests rather
5712 than strcmp() to check for parent directory-ness of an entry. Oh, and
5713 make sure the parent directory (if displayed) is *always* listed first
5714 regardless of the sort key. Overall performance winnage should be good
5715 in CPU time, instruction cache, and memory usage, particularly for large
5716 directories. [Ken Coar]
5718 *) Add a tiny but useful goody to APACI's configure script: The generation
5719 of a config.status script (as GNU Autoconf does) which remembers the used
5720 configure command and hence can be used to restore the configuration by
5721 just re-running this script or for remembering the configuration between
5723 [Ralf S. Engelschall]
5725 *) Add httpd -t (test) option for running configuration syntax tests only.
5726 If something is broken it complains and exits with a return code
5727 non-equal to 0. This can be used manually by the user to check the Apache
5728 configuration after editing and is also automatically used by apachectl
5729 on (graceful) restart command to make sure Apache doesn't die on restarts
5730 because of a configuration which is now broken since the last (re)start.
5731 This way `apachectl restart' can be used inside cronjobs without having
5732 to expect Apache to be falling down. Additionally the httpd -t can be run
5733 via `apachectl configtest'.

5885 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5886 was updated to use the normal apache error processing, thereby allowing
5887 proxy errors to be treated by ErrorDocument's as well. For this
5888 purpose, a new module-to-core communication variable "error-notes"
5889 was introduced; the proxy (and possibly other modules) communicates
5890 its error text using this variable. Its content is copied to a new
5891 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5892 The old proxy special error routine ap_proxy_log_uerror()

5973 *) The Makefiles assumed that DSO files are build via $(LD). This
5974 is broken for two reasons: First we never defined at least LD=ld
5975 somewhere to make sure this works (it was silently assumed that most Make
5976 provide a built-in LD definition - ARGL!) and second using the generic LD
5977 variable is not the truth. Instead a special variable named LD_SHLIB is
5978 reasonable because although "ld" is usually the default, the command for
5979 building DSO files can be "libtool" or even "cc" on some systems.
5980 [Ralf S. Engelschall]
5982 *) Replace the AddVersionPlatform directive with ServerTokens which
5983 provides for more control over the format of the Server:
5984 header line. SERVER_SUBVERSION is no longer supported;
5985 all module should use the ap_add_version_component()
5986 API function instead. [Jim Jagielski]
5988 *) Support for the NCR MP/RAS 3.0
5989 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5991 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5992 not retrieved in src/Configure and thus was not useable.
5993 [Ralf S. Engelschall]
5995 *) Various Makefile consistency cleanups:
5996 - make OSDIR also automatically be relative to src/ like INCDIR
5997 - SUBDIRS is now generated in src/Makefile only and not in
5998 Makefile.config because it is a local define for this location.
5999 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
6000 any Makefile but make sure that at least the "-K inline" is kept in
6002 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
6003 - updated the dependencies theirself
6004 - removed not existing SHLIB variable from "clean" targets
6005 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
6006 already exists and OBJS_PIC are also just plain objects and have not
6007 directly to do with "shared" things. The only difference is that they
6008 contain PIC. So OBJS_PIC is the more canonical name.
6009 - Updated the Makefile-dependency lines for OBJS_PIC
6010 - Removed the Makefile-dependency line in Configure to avoid double
6012 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
6013 of xxx.lo as GNU libtool does with its PIC objects
6014 - reduce local complexity in modules Makefile.tmpl by moving the last
6015 existing target "depend" to the generation section in Configure, too.
6016 - removed the historical $(SPACER) which was used in the past together
6017 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
6018 is no longer needed.
6019 - force the build and run of the gen_xxx programs under main/ as the
6020 first step before building the objects because it looks cleaner
6021 [Ralf S. Engelschall]
6023 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
6026 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
6029 *) WIN32: Don't force ISAPI headers to finish with \n.
6030 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
6032 *) When opening "configuration" files (like httpd.conf, htaccess
6033 and htpasswd), Apache will not allow them to be non-/dev/null
6034 device files. This closes a DoS hole. At the same time,
6035 we use ap_pfopen to open these files to handle timeouts.
6036 [Jim Jagielski, Martin Kraemer]
6038 *) Apache will now log the reason its httpd children exit if they exit
6039 due to an unexpected signal. (It requires a new porting define,
6040 SYS_SIGLIST, which if defined should point to a list of text
6041 descriptions of the signals available. See PORTING.) [Dean Gaudet]
6043 *) WIN32: chdir() doesn't make sense in a multithreaded environment
6044 like WIN32. Before, Win32 CGI's could have had sporadic failures
6045 if a chdir call from one thread was made between another chdir call
6046 and a spawn in another thread. So, for now don't chdir for CGI scripts
6047 in WIN32. The current CGI "spec" is unclear as to whether it's
6048 necessary. Long-term fix is to either serialize the chdir/spawn combo
6049 or use WIN32 native calls to spawn a process. This temp fix was
6050 necessary to remove this as a showstopper for 1.3's release.
6053 *) Cleanup the suEXEC support in APACI and make it more safe:
6054 1. Add big fat hint in INSTALL about risks and to read the
6055 htdocs/manual/suexec.html document before using the suexec-related
6057 2. Make sure the user has at least provided one --suexec-xxxx option
6058 (specifies suEXEC parameters) in addition to --enable-suexec option.
6059 If only --enable-suexec is given APACI stops with a hint to INSTALL
6060 and htdocs/manual/suexec.html documents.
6061 3. Provide two additional --suexec-xxxx options to make the suEXEC
6062 configuration complete (especially for package maintainers who else
6063 had to patch the source tree) by providing ways to configure minimal
6064 UID/GID and safe PATH, too.
6065 [Ralf S. Engelschall]
6067 *) Cleanup of the `configure --shadow' process:
6068 - make sure the configure script creates its temporary files in the
6069 shadow tree to avoid conflicts with parallel configure runs
6070 - removed unnecessary option "-r" from "rm" call for Makefiles
6071 - make sure the configure scripts creates the shadow-wrapper Makefile
6072 only when no shadow trees already exists
6073 - make sure "make distclean" removes the shadow-wrapper Makefile but only
6074 when no more shadow trees exists
6075 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
6076 as fast (in the past it needed 70sec, now it runs just 38sec)
6077 - make sure CVS does not complain about the created files
6078 Makefille.<gnutriple> and directories src.<gnutriple>
6079 [Ralf S. Engelschall]
6081 *) Added the ap_add_version_component() API routine and the
6082 AddVersionPlatform core directive. The first allows modules to
6083 declare themselves in the Server response header field value,
6084 augmenting the SERVER_SUBVERSION define in the Configuration file
6085 with run-time settings (more useful in a loadable-module environment).
6086 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
6087 into the server version string. [Ken Coar] PR#2056
6089 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
6092 *) Emit the "Accept-Range" header for the default handler.
6093 [Brian Behlendorf] PR#1464
6095 *) Add a note to httpd.conf-dist that apache will on some systems fail
6096 to start when the Group # is set to a negative or large positive value.
6099 *) Make sure the module execution order is correct even when some modules
6100 are loaded under runtime (`LoadModule') via the DSO mechanism:
6101 1. The list of loaded modules is now a dynamically allocated one
6102 and not the original statically list from modules.c
6103 2. The loaded modules are now correctly setup by LoadModule for
6104 later use by the AddModule command.
6105 3. When the DSO mechanism for modules is used APACI's `install'
6106 target now enables all created `LoadModule' lines per default because
6107 this is both already expected by the user _and_ needed to avoid
6108 confusion with the next point and reduces the Makefile.tmpl complexity
6109 4. When the DSO mechanism for modules is used, APACI's `install'
6110 target now additionally makes sure the module list is reconstructed
6111 via a complete `ClearModuleList+AddModule...' entry.
6112 5. The support tool `apxs' now also makes sure an AddModule command
6113 is added in addition to the LoadModule command.
6114 6. The modules.c generation was extended to now contain two
6115 comments to make sure no one is confused by the confusing terminology
6116 of loading/linking (we use load=link+load & link=activate instead of
6117 the obvious load=activate & link=link :-( )
6118 This way now there is no longer a difference under execution time between
6119 statically and dynamically linked modules.

6123 Big Symbol Renaming. [Ralf S. Engelschall]

6128 *) Standardized the time format in mod_status to match that of other
6129 places in the code (e.g. DATE_GMT). PR#1551
6131 *) Fix handling of %Z in timefmt strings for those platforms with no time
6132 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
6135 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
6136 feature compatible with 'UseCanonicalName off' by changing
6137 r->server->server_hostname to ap_get_server_name(). And I changed some
6138 functions which use r->server->port to use ap_get_server_port() instead,
6139 because if there's no Port directive in the config r->server->port is 0.
6142 *) get/set_module_config are trivial enough to be better off inline. Worth
6143 1.5% performance boost. [Dean Gaudet]

6146 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
6149 *) [BS2000 security] BS2000 needs an extra authentication to initialize
6150 the task environment to the unprivileged User id. Otherwise CGI scripts
6151 would have a way to gain super user access. [Martin Kraemer]
6153 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
6154 absolute path, only log base name of logging source as is done
6155 in unix. [Martin Kraemer]
6157 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6158 the encoding type from the Accept-Encoding header (if it's there)
6159 and use it in the response, as that's probably what it'll be expecting.
6160 [Ronald.Tschalaer@psi.ch]
6162 *) Fix to mod_alias: translate_alias_redir is dealing with

6189 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6190 Additionally the checks for finding the vendor DSO library were moved
6191 from mod_so.c to Configure because first it needs $PLAT etc. and second
6192 mod_so already uses an abstraction layer and does not fiddle with the
6193 vendor functions itself.

6199 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6200 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6202 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6203 AIX variants should work fine, too. Even AIX 3.x should work). This is
6204 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6205 which we put into a os/unix/os-dso-aix.c file.
6206 [Ralf S. Engelschall]
6208 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6209 that we should use NET_SIZE_T == int but the include files force size_t.
6210 [Ralf S. Engelschall]
6212 *) Fix two bugs in select() handling in http_main.c.
6215 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6216 is unset (as it is in situations like timeouts) where it is unclear
6217 whether errno is set or not. [Martin Kraemer]
6219 *) Just having APACI's localstatedir is too general and not enough for most
6220 of the systems. 1.3b6 again required manual APACI patches by package
6221 maintainers from RedHat and FreeBSD because for their filesystem layout a
6222 little bit more flexibility in configuring the paths is needed. Hence we
6223 provide three additional configure options (--runtimedir, --logfiledir,
6224 --proxycachedir) which now can be used for more granular adjustments if
6225 --localstatedir is not enough to fit the particular needs. As a nice
6226 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6227 [Ralf S. Engelschall]
6229 *) Make the install root for "make install" in APACI's Makefile overrideable
6230 by package authors. This way we are even more friendly to package
6231 maintainers (especially Debian and RedHat) who build for the real prefix
6232 via "configure --prefix=/<real>" but use a different local prefix via
6233 "make root=/tmp/apache install" for rolling the package without bristling
6234 the target location on their system.
6235 [Ralf S. Engelschall]
6237 *) Workaround sed limitations in APACI's configure script by now
6238 substituting in chunks of 50 commands (because for instance HPUX's vendor
6239 sed has a limit of max. 98 commands)

6247 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6248 [Ralf S. Engelschall]
6250 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6251 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6252 [Ralf S. Engelschall] PR#2139
6254 *) Various bugfixes and cleanups for the APACI configure script:
6255 o fix IFS handling for _nested_ situation
6256 o fix Perl interpreter search: take first one found instead of last one
6257 o fix DSO consistency check
6258 o print error messages to stderr instead of stdout
6259 o add install-quiet for --shadow situation to Makefile stub
6260 o reduce complexity by avoiding sed-hacks for rule and module list loops
6261 [Ralf S. Engelschall]
6263 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6265 *) Make sure the input field separator (IFS) shell variable is explicitly
6266 initialized correctly before _every_ `for' loop and also restored after
6267 the loops. [Ralf S. Engelschall]
6269 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6270 `magic' files from an existing Apache installation. Because people often
6271 customize these for own MIME and content types.

6278 [Ralf S. Engelschall] PR#2105
6280 *) Let "configure" clear out the users parameters (provided as shell

6309 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6311 *) If you start apache with the -S command line option it will dump
6312 out the parsed vhost settings. This is useful for folks trying
6313 to figure out what is wrong with their vhost configuration.
6314 (Other dumps may be added in the future.) [Dean Gaudet]
6316 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6317 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6320 *) Because /usr/local/apache is the default prefix the ``configure
6321 --compat'' option no longer has to set prefix, again. This way the
6322 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6324 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6325 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6326 to avoid "discard const" warnings. [Ralf S. Engelschall]
6328 *) If a specific handler is set for a file yet the request still
6329 ends up being handled by the default handler, log an error
6330 message before handling it. This catches things such as trying
6331 to use SSIs without mod_include enabled. [Marc Slemko]
6333 *) Fix error logging for the startup case where ap_log_error() still uses
6334 stderr as the target. Now the default log level is honored here, too.

6344 Changes with Apache 1.3b6
6346 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6348 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6349 interface via the similar but proprietary HP/UX shl_xxx-style system
6350 calls. [Ralf S. Engelschall]
6352 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6353 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6354 Make. [Ralf S. Engelschall]
6356 *) ++++ THE BIG SYMBOL RENAMING ++++
6357 To avoid symbol clashes with third-party code compiled into the server,
6358 we globally applied the prefix "ap_" to the following classes of
6360 - Apache provided general functions (e.g., ap_cpystrn)
6361 - Public API functions (e.g., palloc, bgets)
6362 - Private functions which we can't make static (because of
6363 cross-object usage) but should be (e.g., new_connection)
6364 For backward source compatibility a new header file named compat.h was
6365 created which provides defines for the old symbol names and can be used
6366 by third-party module authors.
6369 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6370 problem under SVR4 is that there is no command flag to force the linker
6371 to export the global symbols of the httpd executable therewith they are
6372 available to the DSO's. Instead of problematic hacks like creating a
6373 dummy.so file (containing dummy references to all global symbols) the
6374 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6375 Placing the Apache core code itself into a DSO library named libhttpd.so.
6376 This way the global symbols _HAVE_ to be exported and thus are available
6377 to any manually loaded DSO's under runtime. To reduce the impact to the
6378 user to null we go even further and create a stub httpd executable which
6379 automatically keeps track of the DSO library loading itself and thus
6380 hides the complete mechanism from the user. Although the generation of
6381 this DSO library is automatically triggered for platforms which
6382 essentially need it (mostly all SVR4-derivates) it can be also enabled
6383 manually via the Rule SHARED_CORE. This can be interesting in the future
6384 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6385 features like graceful upgrades, or whatever.
6386 [Ralf S. Engelschall, Martin Kraemer]
6388 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6390 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6391 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6392 conventions while "clean" removes only stuff created by "all" targets,
6393 "distclean" additionally removes the stuff from the configuration
6394 process. This way "make distclean" (hence the name) provides a fresh
6395 source tree as it was for distribution.
6396 [Ralf S. Engelschall]
6398 *) Allow top-level (APACI) Makefile to break on build errors
6399 the same way the src/ subtree Makefiles breaks on them by replacing the
6400 initial APACI sed-subdir-display-kludge with a more clean
6401 variable-passing-solution: variable SDP can optionally hold the subdir
6402 prefix which is consistently used for displaying the subdir movement.
6403 This way even the top-level Makefile can stop correctly on errors as the
6404 user expects. [Ralf S. Engelschall]
6406 *) Fixed ordering of argument checks for RewriteBase directive.
6407 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6409 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6410 indicating that a module is being compiled for dynamic loading. Also
6411 remove #define IS_MODULE from modules and add SHARED_MODULE define
6412 to the mak/dsp files. [Alexei Kosut]
6414 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6415 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6417 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6419 *) Add documentation file and src/Configuration.tmpl entry for the
6420 experimental mod_mmap_static module. Because although it is and marked as
6421 an experimental one it is distributed and thus should be documented and
6422 prepared for configuration the same way as all others modules.
6423 [Ralf S. Engelschall]
6425 *) Add query (-q) option to apxs support tool to be able to manually query
6426 specific settings from apxs. This is needed for instance when you
6427 manually want to access Apache's header files and you need to assemble
6428 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6429 [Ralf S. Engelschall]
6431 *) Now src/Configure uses a fallback strategy for the shared object support
6432 on platforms where no explicit information is available: If a Perl
6433 installation exists we ask it about its shared object support and if it's
6434 the dlopen-style one we shamelessly guess the compiler and linker flags
6435 for creating shared objects from Perls knowledge. Of course, the user is
6436 warning about what we are doing and informed that he should send us
6437 the guessed flags when they work. [Ralf S. Engelschall]
6439 *) Provide APACI --without-support option to be able to disable the build
6440 and installation of the support tools from the src/support/ area.
6441 Although its useful to have these installed per default we should provide
6442 a way to compile and install without them for backward-compatibility.
6443 [Ralf S. Engelschall]
6445 *) Add of the new APache eXtenSion (apxs) support tool for building and
6446 installing modules into an _already installed_ Apache package through the
6447 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6448 this approach actually doesn't need the Apache source tree. The
6449 (APACI-installed) server package is enough, because this now includes the
6450 Apache C header files (PREFIX/include) and the new APXS tool
6451 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6452 module authors to build their Apache modules _OUTSIDE_ the Apache source
6453 tree while avoiding them to fiddle around with the totally platform
6454 dependend way of compiling DSO files. The tool supports all ranges of
6455 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6456 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6457 on-the-fly generate a minimalistic Makefile and sample module for the
6458 first step to provide both a quick success event and to demonstrate the
6459 APXS mechanism to module authors. [Ralf S. Engelschall]
6461 *) Fix core dumps in use of CONNECT in proxy.
6462 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6464 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6465 so that users have examples of how CustomLog can be used.
6468 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6469 the Apache distribution tree. Until Apache 1.3 there was no real
6470 out-of-the-box batch-capable build and installation procedure for the
6471 complete Apache package. This is now provided by a top-level "configure"
6472 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6473 to provide a GNU Autoconf-style frontend which is capable to both drive
6474 the old src/Configure stuff in batch and additionally installs the
6475 package with a GNU-conforming directory layout. Any options from the old
6476 configuration scheme are available plus a lot of new options for flexibly
6477 customizing Apache. [Ralf S. Engelschall]
6479 *) The floating point ap_snprintf code wasn't threadsafe.
6480 Had to remove the HAVE_CVT macro in order to do threadsafe
6481 calling of the ?cvt() floating point routines. [Dean Gaudet]
6483 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6485 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
6486 [Jim Jagielski] PR#1901
6488 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6489 Configure knows which CC we are using. [Jim Jagielski]
6491 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6492 was defined in a parent directory. [Lars Eilebrecht]
6494 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6495 a generic printf-style routine that can call arbitrary output
6496 routines. Use this to replace http_bprintf.c. Add new routines
6497 psprintf(), pvsprintf() which allocate the exact amount of memory
6498 required for a string from a pool. Use psprintf() to clean up
6499 various bits of code which used ap_snprintf()/pstrdup().
6502 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6503 ap_snprintf() has different semantics and formatting codes than
6504 snprintf(). [Dean Gaudet]
6506 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6507 is necessary on at least Solaris where the /etc/rc?.d scripts
6508 are run with these signals ignored, and "SIG_IGN" settings are
6509 maintained across exec().
6510 [Rein Tollevik <reint@sys.sol.no>] PR#2009
6512 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
6513 used instead of lstat() and thus this flag didn't work as expected.
6514 [Rein Tollevik <reint@sys.sol.no>] PR#2010
6516 *) Fix the proxy pass-through feature of mod_rewrite for the case of
6517 existing QUERY_STRING now that mod_proxy was recently changed because of
6518 the new URL parsing stuff. [Ralf S. Engelschall]
6520 *) A few changes to scoreboard definitions which helps gcc generate
6521 better code. [Dean Gaudet]
6523 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
6524 be a signed bitfield. So mark a few bitfields as signed to
6525 ensure correct code. [Dean Gaudet]
6527 *) The default for HostnameLookups was changed to Off, but there
6528 was a problem and it wasn't taking effect. [Dean Gaudet]
6530 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
6533 *) After a SIGHUP the listening sockets in the parent weren't
6534 properly marked for closure on fork().
6535 [Jürgen Keil <jk@tools.de>] PR#2000
6537 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6538 therefore not exposed to %2F -> '/' translations and 2) the request
6539 is a proxy request, so we're not dealing with a local resource anyway.
6540 Without this, the proxy would fail to work for any URL's with
6541 %2f in them (occurs quite often in
6542 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6544 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6546 *) Make the shared object compilation command more portable by avoiding
6547 the direct combination of `-c' & `-o' which is not honored by some
6548 compilers like UnixWare's cc. [Ralf S. Engelschall]
6550 *) WIN32: the proxy was creating filenames missing the last four
6551 characters. While this normally doesn't stop anything from
6552 working, it can result in extra collisions.
6553 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
6555 *) Now mod_proxy uses the response string (in addition to the response status
6556 code) from the already used FTP SIZE command to setup the Content-Length
6557 header if available. [Ralf S. Engelschall] PR#1183
6559 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6560 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6561 name was really too generic, added documentation for this directive to
6562 the mod_proxy.html and corrected the hyperlink to it in the
6563 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
6565 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6566 faster [Martin Kraemer]
6568 *) Make Configure die when you give it an unknown command switch.
6571 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6572 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6573 and per default compiled support programs have manual pages - just to
6574 document our stuff a little bit more and to be able to do really
6575 Unix-like installations ;-) [Ralf S. Engelschall]
6577 *) Major cleanups to the Configure script to make it and its generated
6578 Makefiles again readable and maintainable: add SRCDIR option, removed
6579 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6580 generated sections, consequently added Makefile headers with inheritance
6581 information, added subdir movement messages for easier following where
6582 the build process currently stays (more verbose then standard Make, less
6583 verbose than GNU make), same style to comments in the Configure script,
6584 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6586 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6587 from the ZeusBench benchmarking program and can be used to determine the
6588 response performance of an Apache installation. This version is
6589 officially licensed with Zeus Technology, Ltd. See the license agreement
6590 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
6591 [Ralf S. Engelschall]
6593 *) API: Various core functions that are definately not part of the API
6594 have been made static, and a few have been marked API_EXPORT. Still
6595 more have been marked CORE_EXPORT and are not intended for general
6596 use by modules. [Doug MacEachern, Dean Gaudet]
6598 *) mod_proxy was not clearing the Proxy-Connection header from
6599 requests; now it does. This did not violate any spec, however
6600 causes poor interactions when you are talking to remote proxies.
6601 [Marc Slemko] PR#1741
6603 *) Various cleanups to the command line interface and manual pages.
6604 [Ralf S. Engelschall]
6606 *) cfg_getline() was not properly handling lines that did not end
6607 with a line termination character. [Marc Slemko] PR#1869, 1909
6609 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6611 *) Clean up some undocumented behavior of mod_setenvif related to
6612 "merging" two SetEnvIf directives when they match the same header
6613 and regex. Document that mod_setenvif will perform comparisons in
6614 the order they appear in the config file. Optimize mod_setenvif by
6615 doing more work at config time rather than at runtime.
6618 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6619 to allow for modules to overrule them and to reduce redefinition
6620 warnings [Jim Jagielski]
6622 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6625 *) Making the hard-coded cross-module function call mime_find_ct() (from
6626 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6627 checking is really called even for proxy requests except for URLs with
6628 HTTP schemes (because there we can optimize by not running the type
6629 checking hooks due to the fact that the proxy gets the MIME Content-type
6630 from the remote host later). This change cleans up mod_mime by removing
6631 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6632 especially unbundles mod_proxy and mod_mime. This way they both now can
6633 be compiled as shared objects and are no longer tied together.
6634 [Ralf S. Engelschall]
6636 *) util.c cleanup and speedup. [Dean Gaudet]
6638 *) API: Clarification, pstrndup() will always copy n bytes of the source
6639 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6641 *) Mark module command_rec and handler_rec structures const so that they
6642 end up in the read-only data section (and are friendlier to systems
6643 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6645 *) Add check to the "Port" directive to make sure the specified
6646 port is in the appropriate range. [Ben Hyde]
6648 *) Performance improvements to invoke_handler().
6649 [Dmitry Khrustalev <dima@bog.msu.su>]
6651 *) Added support for building shared objects even for library-style modules
6652 (which are built from more than one object file). This now provides the
6653 ability to build mod_proxy as a shared object module. Additionally
6654 modules like mod_example are now also supported for shared object
6655 building because the generated Makefiles now no longer assume there is at
6656 least one statically linked module. [Ralf S. Engelschall]
6658 *) API: Clarify usage of content_type, handler, content_encoding,
6659 content_language and content_languages fields in request_rec. They
6660 must always be lowercased; and the strings pointed to shouldn't
6661 be modified (you must copy them to modify them). Fix a few bugs
6662 related to this. [Dean Gaudet]
6664 *) API: Clarification: except for RAW_ARGS, all command handlers can
6665 treat the char * parameters as permanent, and modifiable. There
6666 is no need to pstrdup() them. Clean up some needless pstrdup().
6669 *) Now mod_so keeps track of which module shared objects with which names
6670 are loaded and thus avoids multiple loading and unloading and irritating
6671 error_log messages. [Ralf S. Engelschall]
6673 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6674 environment variable in the apache core. But that tweaking interferes
6675 with mod_setenv. So don't tweak if the user has specified an explicit
6676 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6678 *) rputs() did not calculate r->sent_bodyct properly.
6679 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6681 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6682 name, or left unset if this value is unavailable. Apache was setting
6683 it to the IP address when unavailable.
6684 [Tony Finch <fanf@demon.net>] PR#1925
6686 *) Various improvements to the configuration and build support for compiling
6687 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6688 OSF1 support with GCC and vendor compilers was added. This way shared
6689 object support is now provided out-of-the-box for FreeBSD, Linux,
6690 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6691 [Ralf S. Engelschall]
6693 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6694 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6695 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6697 *) Fix one more special locking problem for RewriteMap programs in
6698 mod_rewrite: According to the documentation of flock(), "Locks are on
6699 files, not file descriptors. That is, file descriptors duplicated
6700 through dup(2) or fork(2) do not result in multiple instances of a lock,
6701 but rather multiple references to a single lock. If a process holding a
6702 lock on a file forks and the child explicitly unlocks the file, the
6703 parent will lose its lock.". To overcome this we have to make sure the
6704 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6705 the case by opening it in the child_init instead of the module_init API
6706 hook. [Ralf S. Engelschall] PR#1029
6708 *) Change to Location and LocationMatch semantics. LocationMatch no
6709 longer lets a single slash match multiple adjacent slashes in the
6710 URL. This change is for consistency with RewriteRule and
6711 AliasMatch. Multiple slashes have meaning in URLs that they do
6712 not have in (some) filesystems. Location on the other hand can
6713 be considered a shorthand for a more complicated regex, and it
6714 does match multiple slashes with a single slash -- which is
6715 also consistent with the Alias directive.
6716 [Dean Gaudet] related PR#1440
6718 *) Fix bug with mod_mime_magic causing certain files, including files
6719 of length 0, to result in no response from the server.
6722 *) The Configure script now generates src/include/ap_config.h which
6723 contains the set of defines used when Apache is compiled on a platform.
6724 This file can then be included by external modules before including
6725 any Apache header files in case they are being built separately from
6726 Apache. Along with this change, a couple of minor changes were
6727 made to make Apache's #defines coexist peacefully with any autoconf
6728 defines an external module might have. [Rasmus Lerdorf]
6730 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6731 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6732 chance by the API to initialize its per-server configuration and thus
6733 receives the wrong one from the main server. This is now avoided by
6734 remembering the server together with the config structure while
6735 configuring and later assuming there is no config when we see a
6736 difference between the remembered server and the one calling us.
6737 [Ralf S. Engelschall] PR#1790
6739 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6740 is automatically disabled under configure time when the dbm_xxx functions
6741 are not available. Second, two heavy source code errors in the DBM
6742 support code were fixed. This makes DBM RewriteMap's usable again after
6743 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6745 *) Now all configuration files support Unix-style line-continuation via
6746 the trailing backslash ("\") character. This enables us to write down
6747 complex or just very long directives in a more readable way. The
6748 backslash character has to be really the last character before the
6749 newline and it has not been prefixed by another (escaping) backslash.
6750 [Ralf S. Engelschall]
6752 *) When using ProxyPass the ?querystring was not passed correctly.
6753 [Joel Truher <truher@wired.com>]
6755 *) To deal with modules being compiled and [dynamically] linked
6756 at a different time from the core, the SERVER_VERSION and
6757 SERVER_BUILT symbols have been abstracted through the new
6758 API routines apapi_get_server_version() and apapi_get_server_built().
6761 *) WIN32: Preserve trailing slash in canonical path (and hence
6762 in PATH_INFO). [Paul Sutton, Ben Laurie]
6764 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6765 depending on the rev of Solaris and what mixture of modules
6766 are in use. So it has been disabled, and Solaris is back to
6767 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6768 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6769 up static content only servers. Or it may fail unpredictably.
6770 [Dean Gaudet] PR#1779, 1854, 1904
6772 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6775 *) API: Rewrite of absoluteURI handling, and in particular how
6776 absoluteURIs match vhosts. Unless a request is a proxy request, a
6777 "http://host" url is treated as if a similar "Host:" header had been
6778 supplied. This change was made to support future HTTP/1.x protocols
6779 which may require clients to send absoluteURIs for all requests.
6781 In order to achieve this change subtle changes were made to the API. In a
6782 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6783 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6784 by the core, modules must set it during the post_read_request or
6785 translate_names phase.
6787 Plus changes to the virtualhost test suite for absoluteURI testing.
6789 This fixes several bugs with the proxy proxying requests to vhosts
6790 managed by the same httpd.
6793 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6794 code from mod_rewrite. The vhost matching is now performed by a
6795 globally available function matches_request_vhost(). [Dean Gaudet]
6797 *) Reduce memory usage, and speed up ServerAlias support. As a
6798 side-effect users can list multiple ServerAlias directives
6799 and they're all considered.

6811 *) API: A new source module main/util_uri.c; It contains a routine
6812 parse_uri_components() and friends which breaks a URI into its component
6813 parts. These parts are stored in a uri_components structure called
6814 parsed_uri within each request_rec, and are available to all modules.
6815 Additionally, an unparse routine is supplied which re-assembles the URI
6816 components back to an URI, optionally hiding the username:password@ part
6817 from ftp proxy requests, and other useful routines. Within the structure,
6818 you find on a ready-for-use basis:
6819 scheme; /* scheme ("http"/"ftp"/...) */
6820 hostinfo; /* combined [user[:password]@]host[:port] */
6821 user; /* user name, as in http://user:passwd@host:port/ */
6822 password; /* password, as in http://user:passwd@host:port/ */
6823 hostname; /* hostname from URI (or from Host: header) */
6824 port_str; /* port string (integer representation is in "port") */
6825 path; /* the request path (or "/" if only scheme://host was given) */
6826 query; /* Everything after a '?' in the path, if present */
6827 fragment; /* Trailing "#fragment" string, if present */
6828 This is meant to serve as the platform for *BIG* savings in
6829 code complexity for the proxy module (and maybe the vhost logic).
6832 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6833 ${map:key}) available for all location where a string is created in
6834 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6835 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6836 possible expansions are consequently usable at all string creation
6837 locations. [Ralf S. Engelschall]
6839 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6840 and not 1) and the per-virtual-server merging of directives. Now all
6841 directives except `RewriteEngine' and `RewriteOption' are either
6842 completely overridden (default) or completely inherited (when
6843 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6849 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6850 server to bind to port 0 rather than 80. [Dean Gaudet]
6852 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6853 (like SunOS and FreeBSD) which don't accept the locking of pipes
6854 directly. A new directive RewriteLock is introduced which can be used to
6855 setup a separate locking file which then is used for synchronization.

6870 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6871 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6873 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6874 type but with a special post-processing for the looked-up value: It
6875 parses it into alternatives according to `|' chars and then only one
6876 particular alternative is chosen randomly (this is an essential
6877 functionality needed for balancing between backend-servers when using
6878 Apache as a Reverse Proxy. The looked up value here is a list of
6879 servers). Second, `int' with the built-in maps named `tolower' and
6880 `toupper' which can be used to map URL parts to a fixed case (this is an
6881 essential feature to fix the case of server names when doing mass
6882 virtual-hosting with the help of mod_rewrite instead of using
6883 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6884 Jay Soffian <jay@cimedia.com>] PR#1631
6886 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6887 This directive lets Apache adjust the URL in Location-headers on HTTP
6888 redirect responses sent by the remote server. This way the virtually
6889 mapped area is no longer left on redirects and thus by-passed which is
6890 especially essential when running Apache as a reverse proxy.

6937 *) mod_mime_magic error message should indicate the filename when
6938 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
6940 *) Previously Apache would permit </Files> to end <FilesMatch> (and
6941 similary for Location and Directory), now this is diagnosed as an
6942 error. Improve error messages for mismatched sections (<Files>,
6943 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
6944 [Dean Gaudet, Martin Kraemer]
6946 *) <Files> is not permitted within <Location> (because of the
6947 semantic ordering). [Dean Gaudet] PR#379
6949 *) <Files> with wildcards was broken by the change in wildcard
6950 semantics (* does not match /). To fix this, <Files> now
6951 apply only to the basename of the request filename. This
6952 fixes some other inconsistencies in <Files> semantics
6953 (such as <Files a*b> not working). [Dean Gaudet] PR#1817
6955 *) Removed bogus "dist.tar" target from Makefile.tmpl and make sure
6956 backup files are removed on "clean" target [Ralf S. Engelschall]
6958 *) PORT: Add -lm to LIBS for HPUX. [Dean Gaudet] PR#1639
6960 *) Various errors from select() and accept() in child_main() would
6961 result in an infinite loop. It seems these two tickle kernel
6962 or library bugs occasionally, and result in log spammage and
6963 a generally bad scene. Now the child exits immediately,
6964 which seems to be a good workaround.

6978 Changes with Apache 1.3b5
6980 *) Source file dependencies in Makefile.tmpl files throughout the
6981 source tree were updated to accurately reflect reality.
6984 *) Preserve the content encoding given by the AddEncoding directive
6985 when the client doesn't otherwise specify an encoding.

6988 *) Sort out problems with canonical filename handling happening too late.
6989 [Dean Gaudet, Ben Laurie]
6991 Changes with Apache 1.3b4
6993 *) The module structure was modified to include a *dynamic_load_handle
6994 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
6995 has been bumped accordingly. [Paul Sutton]
6997 *) All BrowserMatch directives mentioned in
6998 htdocs/manual/known_client_problems.html are in the default
6999 configuration files. [Lars Eilebrecht]
7001 *) MiNT port update. [Jan Paul Schmidt]
7003 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
7004 equivalent, similarly for x-compress and compress. Apache
7005 now ignores a leading x- when comparing encodings. It also
7006 preserves the encoding the client requests (for example if
7007 it requests x-gzip, then Apache will respond with x-gzip
7008 in the Content-Encoding header).
7009 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
7011 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
7013 *) Added mod_so module to support dynamic loading of modules on Unix
7014 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
7015 instead of AddModule in Configuration to build shared modules
7016 [Sameer Parekh, Paul Sutton]
7018 *) Minor cleanups to r->finfo handling in some modules.
7021 *) Abstract read()/write() to ap_read()/ap_write().
7022 Makes it easier to add other types of IO code such as SFIO.
7025 *) API: Generalize default_port manipulations to make support of
7026 different protocols easier. [Ben Laurie, Randy Terbush]
7028 *) There are many cases where users do not want Apache to form
7029 self-referential urls using the "canonical" ServerName and Port.
7030 The new UseCanonicalName directive (default on), if set to off
7031 will cause Apache to use the client-supplied hostname and port.
7032 API: Part of this change required a change to the construct_url()
7033 prototype; and the addition of get_server_name() and
7035 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
7036 PR#315, 459, 485, 1433
7038 *) Yet another rearrangement of the source tree.. now all the common
7039 header files are in the src/include directory. The -Imain -Iap
7040 references in Makefiles have been changed to the simpler -Iinclude
7041 instead. In addition to simplifying the build a little bit, this
7042 also makes it clear when a module is referencing something in a
7043 other than kosher manner (e.g., the proxy including mod_mime.h).
7044 Module-private header files (the proxy, mod_mime, the regex library,
7045 and mod_rewrite) have not been moved to src/include; nor have
7046 the OS-abstraction files. [Ken Coar]
7048 *) Fix a bug where r->hostname didn't have the :port stripped
7049 from it. [Dean Gaudet]
7051 *) Tweaked the headers_out table size, and the subprocess_env
7052 table size guess in rename_original_environment(). Added
7053 MAKE_TABLE_PROFILE which can help discover make_table()
7054 calls that use too small an initial guess, see alloc.c.
7057 *) Options and AllowOverride weren't properly merging in the main
7058 server setting inside vhosts (only an issue when you have no
7059 <Directory> or other section containing an Options that affects
7060 a request). Options +foo or -foo in the main_server wouldn't
7061 affect the main_server's lookup defaults. [Dean Gaudet]
7063 *) Variable 'cwd' was being used pointlessly before being set.
7066 *) r->allowed handling cleaned up in the standard modules.
7069 *) Some case-sensitivity issues cleaned up to be consistent with
7070 RFC2068. [Dean Gaudet]
7072 *) SIGURG doesn't exist everywhere.
7073 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7075 *) mod_unique_id was erroneously generating a second unique id when
7076 an internal redirect occured. Such redirects occur, for example,
7077 when processing a DirectoryIndex match. [Dean Gaudet]
7079 *) API: table_add, table_merge, and table_set include implicit pstrdup()
7080 of the key and value. But in many cases this is not required
7081 because the key/value is a constant, or the value has been built
7082 by pstrcat() or other similar means. New routines table_addn,
7083 table_mergen, and table_setn have been added to the API, these
7084 routines do not pstrdup() their arguments. The core code and
7085 standard modules were changed to take advantage of these routines.
7086 The resulting server is up to 20% faster in some situations.
7088 Note that it is easy to get code subtly wrong if you pass a key/value
7089 which is in a pool other than the pool of the table. The only
7090 safe thing to do is to pass key/values which are in the pool of
7091 the table, or in one of the ancestors of the pool of the table.
7092 i.e. if the table is part of a subrequest, a value from the main
7093 request's pool is OK since the subrequest pool is a sub_pool of the
7094 main request's pool (and therefore has a lifespan at most as long as
7095 the main pool). There is debugging code which can detect improper
7096 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
7097 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
7099 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
7100 which don't exist on disk more gracefully; handles vhosts properly.
7101 Update documentation to reflect the code -- if there's no
7102 MimeMagicFile directive then the module is not enabled.
7105 *) PORT: Some older *nix dialects cannot automatically start scripts
7106 which begin with a #! interpreter line (the shell starts the scripts
7107 appropriately on these platforms). Apache now supports starting of
7108 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
7109 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
7112 *) API: "typedef array_header table" removed from alloc.h, folks should
7113 have been writing to use table as if it were an opaque type, but even
7114 some standard modules got this wrong. By changing the definition
7115 to "typedef struct table table" module authors will receive compile
7116 time warnings that they're doing the wrong thing. This change
7117 facilitates future changes with more sophisticated table
7118 structures. Specifically, module authors should be using table_elts()
7119 to get access to an array_header * for the table. [Dean Gaudet]
7121 *) API: Renamed new_connection() to avoid namespace collision with LDAP
7122 library routines. [Ken Coar, Rasmus Lerdorf]
7124 *) WIN32: mod_speling is now available on the Win32 platform.
7127 *) For clarity the following compile time definition was changed:
7129 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
7131 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
7132 and not be a general notice that the OS has mmap(). Now the
7133 HAVE_MMAP/SHMGET #defines strictly are informational that the
7134 OS has that method of shared memory; the type to use for
7135 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
7136 and USE_SHMGET_SCOREBOARD). This allows outside modules to
7137 determine if shared memory is available and allows Apache
7138 to determine the best method to use for the scoreboard.
7141 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
7142 as do various earlier versions. It should be safe on all versions.
7143 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
7144 the slack code. A few other cleanups for Unixware.

7147 *) PORT: A/UX can handle single-listen accepts without mutex
7148 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
7150 *) When die() happens we need to eat any request body if one exists.
7151 Otherwise we can't continue with a keepalive session. This shows up
7152 as a POST problem with MSIE 4.0, typically against pages which are
7153 authenticated. [Roy Fielding] PR#1399
7155 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
7156 header will be passed to CGIs. This is generally a security hole, so

7164 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
7166 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
7167 The choice of flock vs. fcntl was made based on timings which showed that
7168 even on non-NFS, non-exported filesystems fcntl() was an order of
7169 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7170 that single socket users will see no difference. [Dean Gaudet] PR#467
7172 *) "File does not exist" error message was erroneously including the
7173 errno. [Marc Slemko]
7175 *) Improve the warning message generated when a client drops the
7176 connection (hits stop button, etc.) during a send. [Roy Fielding]
7178 *) Defining GPROF will disable profiling in the parent and enable it
7179 in the children. If you're profiling under Linux this is pretty much
7180 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
7182 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

7192 *) Some const declarations in mod_imap.c that were added for debugging
7193 purposes caused some compilers heartburn without adding any
7194 significant value, so they've been removed. [Ken Coar]
7196 *) The src/main/*.h header files have had #ifndef wrappers added to
7197 insulate them against duplicate calls if they get included through
7198 multiple paths (e.g., in .c files as well as other .h files).
7201 *) The libap routines now have a header file for their prototypes,
7202 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
7204 *) mod_autoindex with a plaintext header file would emit the <PRE>
7205 start-tag before the HTML preamble, rather than after the preamble
7206 but before the header file contents. [John Van Essen <jve@gamers.org>]
7209 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7210 only an issue on systems without a MAXDNAME define or where
7211 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7213 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7214 is used to read various types of files such as htaccess and
7215 htpasswd files. [Marc Slemko]
7217 *) SECURITY: Ensure that the buffer returned by ht_time is always
7218 properly null terminated. [Marc Slemko]
7220 *) The "Connection" header could be sent back with multiple "close"
7221 tokens. Not an error, but a waste.
7222 [Ronald.Tschalaer@psi.ch] PR#1683
7224 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
7225 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
7227 *) "basic" auth needs a case-insensitive comparison.
7228 [Ronald.Tschalaer@psi.ch] PR#1666
7230 *) For maximum portability, the environment passed to CGIs should
7231 only contain variables whose names match the regex
7232 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
7233 underscores over any character outside the regex. This
7234 affects HTTP_* variables, in a way that should be backward
7235 compatible for all the standard headers; and affects variables
7236 set with SetEnv/BrowserMatch and similar directives.
7239 *) mod_speling returned incorrect HREF's when an ambigous match
7240 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)

7247 *) PORT: Fix problem killing children when terminating. Allow ^C
7248 to shut down the server. [Brian Havard]

7272 possible buffer overflows and a possible infinite loop.
7273 [Dean Gaudet, Marc Slemko]
7275 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7276 including fixing a possible buffer overflow. [Dean Gaudet]
7278 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
7279 (connections are not dropped). Code can handle graceful restarts
7280 (but there is as yet no way to signal this to Apache). Various
7281 other cleanups. [Paul Sutton]
7283 *) The aplog_error changes specific to 1.3 introduced a buffer
7284 overrun in the (now legacy) log_printf function. Fixed.
7287 *) mod_digest didn't properly deal with proxy authentication. It
7288 also lacked a case-insensitive comparision of the "Digest"
7289 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
7291 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
7293 *) A few cleanups in mod_info to make it thread-safe, and remove an
7294 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
7296 *) no2slash() was O(n^2) in the length of the input. Make it O(n).

7300 ap_cpystrn() for performance and functionality reasons.

7317 *) Interim (slow) fix for p->sub_pool critical sections in
7318 alloc.c (affects win32 only). [Ben Hyde]
7320 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
7322 *) send_fd_length() did not calculate total_bytes_sent properly.
7323 [Ben Reser <breser@regnow.com>] PR#1366
7325 *) The bputc() macro was not properly integrated with the chunking
7326 code; in many cases modules using bputc() could cause completely
7327 bogus chunked output. (Typically this will show up as problems
7328 with Internet Explorer 4.0 reading a page, but other browsers
7329 having no problem.) [Dean Gaudet]
7331 *) Create LARGE_WRITE_THRESHOLD define which determines how many
7332 bytes have to be supplied to bwrite() before it will consider
7333 doing a writev() to assemble multiple buffers in one system
7334 call. This is critical for modules such as mod_include,
7335 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
7336 strings in some cases. The result would be extra effort
7337 setting up writev(), and in many cases extra effort building
7338 chunks. The default is 31, it can be overriden at compile
7341 *) Move the gid switching code into the child so that log files
7342 and pid files are opened with the root gid.

7349 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
7350 so the functionality is available to applications other than the
7351 server itself (like the src/support tools). [Ken Coar]
7353 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
7354 the libap consolidation work. [Ken Coar]
7356 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
7357 useful, and isn't what the standards require. Now it returns 0

7461 A new pool was created which is passed to the module child_init
7462 and child_exit functions; modules are free to register per-child
7463 cleanups there. This fixes a bug with reliable piped logs.
7466 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom

7475 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
7476 Now the rewriting engine (the heart of mod_rewrite) is organized more
7477 straight-forward, first time well documented and reduced to the really
7478 essential parts. All redundant cases were stripped off and processing now
7479 is the same for both per-server and per-directory context with only a
7480 minimum difference (the prefix stripping in per-dir context). As a
7481 side-effect some subtle restrictions and two recently discovered problems
7482 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
7483 context and restrictions on the substitution URL on redirects.
7484 Additionally some minor source cleanups were done.

7641 *) TestCompile was not passing $LIBS [Dean Gaudet]
7643 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7646 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7647 rudimentary memory debugger which can be used on live servers with
7648 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7649 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7650 and free() for each object. This is far more expensive and should
7651 only be used for testing with tools such as Electric Fence and
7652 Purify. See main/alloc.c for more details. [Dean Gaudet]
7654 *) Configure uses a sh trap and didn't set its exitcode properly.
7655 [Dean Gaudet] PR#1159
7657 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7658 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7659 From a given ip:port, regardless what the Host: header is, you can
7660 only reach the vhosts defined on that ip:port. The precedence of
7661 vhosts was reversed to match other precedences in the config --
7662 the earlier vhosts override the later vhosts. All vhost matching was
7663 moved into http_vhost.[ch]. [Dean Gaudet]
7665 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7666 be used for whatever reason is appropriate (i.e. format() warnings
7667 for printf style functions). Both are enabled only with
7668 gcc >= 2.7.x (so that we have fewer support issues with older
7669 versions). [Dean Gaudet]
7671 *) Fix support for Proxy Authentication (we were testing the response

7674 *) CoreDumpDirectory directive directs where the core file is

7679 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7681 *) When booting, apache will now detach itself from stdin, stdout,
7682 and stderr. stderr will not be detached until after the config
7683 files have been read so you will be able to see initial error
7684 messages. After that all errors are logged in the error_log.
7685 This makes it more convenient to start apache via rsh, ssh,
7686 or crontabs. [Dean Gaudet] PR#523

7700 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7702 *) mod_autoindex improperly counted &escapes; as more than one
7703 character in the description. It also improperly truncated
7704 descriptions that were exactly the maximum length.
7707 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7708 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7711 *) mod_include now uses symbolic names to check for request success
7712 and return HTTP errors, and correctly handles all types of
7713 redirections (previously it only did temporary redirect correctly).
7714 [Ken Coar, Roy Fielding]
7716 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7717 r->filename. Since those two are meant to be in sync with each other

7730 *) Fixed error in proxy_util.c when looping through multiple host IP
7731 addresses. [Lars Eilebrecht] PR#974
7733 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7734 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7735 bytes before writing, but it will never split a log entry across a
7736 buffer boundary. [Dean Gaudet]
7738 *) API: the short_score record has been split into two pieces, one which
7739 the parent writes on, and one which the child writes on. As part of
7740 this change the get_scoreboard_info() function was removed, and
7741 scoreboard_image was exported. This change fixes a race condition
7742 in file based scoreboard systems, and speeds up changes involving the
7743 scoreboard in earlier 1.3 development. [Dean Gaudet]
7745 *) API: New register_other_child() API (see http_main.h) which allows
7746 modules to register children with the parent for maintenance. It
7747 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7749 *) API: New piped_log API (see http_log.h) which implements piped logs,
7750 and will use register_other_child to implement reliable piped logs
7751 when it is available. The reliable piped logs part can be disabled
7752 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7753 logs is only available on Unix. [Dean Gaudet]
7755 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7756 meets_conditions(). This allows conditional HTTP selection to be
7757 handled separately from the storing of the header fields, and provides
7758 the ability for CGIs to set their own ETags for conditional checking.
7759 [Ken Coar, Roy Fielding] PR#895
7761 *) Changes to mod_log_config to allow naming of format strings.
7762 Format nicknames are defined with "LogFormat fmt nickname", and can
7763 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7766 *) New module, "mod_speling", which can help find files even when
7767 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7769 *) API: New function child_terminate() triggers the child process to
7770 exit, while allowing the child finish what it needs to for the
7771 current request first.
7772 [Doug MacEachern, Alexei Kosut]
7774 *) Windows now defaults to using full status reports with mod_status.
7775 [Alexei Kosut] PR #1094
7777 *) *Really* disable all mod_rewrite operations if the engine is off.
7778 Some things (like RewriteMaps) were checked/performed even if they
7779 weren't supposed to be. [Ken Coar] PR #991
7781 *) Implement a new timer scheme which eliminates the need to call alarm() all
7782 the time. Instead a counter in the scoreboard for each child is used to
7783 show when the child has made forward progress. The parent samples this
7784 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7785 progress has been made in the timeout period. This reduces the static
7786 request best-case syscall count to 22 from 29. This scheme is only
7787 used by systems with memory-based scoreboards. [Dean Gaudet]
7789 *) The proxy now properly handles CONNECT requests which are sent
7790 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7792 *) A script called apachectl has been added to the support
7793 directory. This script allows you to do things such as
7794 "apachectl start" and "apachectl restart" from the command
7797 *) Modules and core routines are now put into libraries, which
7798 simplifies the link line tremendously (among other advantages).
7801 *) Some of the MD5 names defined in Apache have been renamed to have
7802 an `ap_' prefix to avoid conflicts with routines supplied by
7803 external libraries. [Ken Coar]
7805 *) Removal of mod_auth_msql.c from the distribution. There are many
7806 other options for databases today. Rather than offer one option,
7807 offer none at this time. mod_auth_msql and other SQL database
7808 authentication modules can be found at the Apache Module Registry.
7809 http://modules.apache.org/ It would be nice to offer a generic
7810 mod_auth_sql option in the near future.
7812 *) PORT: BeOS support added [Alexei Kosut]
7814 *) Configure no longer accepts the -make option, since it creates
7815 Makefile on the fly based on Makefile.tmpl and Configuration.
7817 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7818 of forcibly killing off all its processes and exiting without
7819 cleaning up. [Alexei Kosut]
7821 *) API: A new field in the request_rec, r->mtime, has been added to
7822 avoid gratuitous parsing of date strings. It is intended to hold
7823 the last-modified date of the resource (if applicable). An
7824 update_mtime() routine has also been added to advance it if
7825 appropriate. [Roy Fielding, Ken Coar]
7827 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7828 deny access to the directory with a HTTP_FORBIDDEN. The previous
7829 behavior was to ignore the htaccess file if it could not be read.
7830 This change may make some setups with unreadable htaccess files
7831 stop working. [Marc Slemko] PR#817
7833 *) Add aplog_error() providing a mechanism to define levels of
7834 verbosity to the server error logging. This addition also provides
7835 the ability to log errors using syslogd. Error logging is configurable
7836 on a per-server basis using the LogLevel directive. Conversion
7837 of log_*() in progress. [Randy Terbush]
7839 *) Further enhance aplog_error() to not log filename, line number, and
7840 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7842 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7843 converted to long ones. Backslashes are converted to forward
7844 slashes. Case is converted to lower. Parts of URLs that do not
7845 correspond to files are left completely alone. [Ben Laurie]
7847 *) PORT: 2 new OSs added to the list of ports:
7848 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7849 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7851 *) Add the server version (SERVER_VERSION macro) to the "server
7852 configured and running" entry in the error_log. Also build an
7853 object file at link-time that contains the current time
7854 (SERVER_BUILT global const char[]), and include that in the
7857 *) Set r->headers_out when sending responses from the proxy.
7858 This fixes things such as the logging of headers sent from
7859 the proxy. [Marc Slemko] PR#659
7861 *) support/httpd_monitor is no longer distributed because the
7862 scoreboard should not be file based if at all possible. Use
7863 mod_status to see current server snapshot.
7865 *) (set_file_slot): New function, allowing auth directives to be
7866 independent of the server root, so the server documents can be
7867 moved to a different directory or machine more easily.
7868 [David J. MacKenzie]
7870 *) If no TransferLog is given explicitly, decline
7871 to log. This supports coexistence with other logging modules,
7872 such as the custom one that UUNET uses. [David J. MacKenzie]
7874 *) Check for titles in server-parsed HTML files.
7875 Ignore leading newlines and returns in titles. The old behavior
7876 of replacing a newline after <title> with a space causes the
7877 title to be misaligned in the listing. [David J. MacKenzie]
7879 *) Change mod_cern_meta to be configurable on a per-directory basis.
7880 [David J. MacKenzie]
7882 *) Add 'Include' directive to allow inclusion of configuration
7883 files within configuration files. [Randy Terbush]
7885 *) Proxy errors on connect() are logged to the error_log (nothing
7886 new); now they include the IP address and port that failed
7887 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7889 *) Various architectures now define USE_MMAP_FILES which causes
7890 the server to use mmap() for static files. There are two
7891 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7892 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7893 number of bytes written in one cycle from a single mmap()d object,
7894 default 32768). [Dean Gaudet]
7896 *) API: Added post_read_request API phase which is run right after reading
7897 the request from a client, or right after an internal redirect. It is
7898 useful for modules setting environment variables that depend only on
7899 the headers/contents of the request. It does not run during subrequests
7900 because subrequests inherit pretty much everything from the main
7901 request. [Dean Gaudet]
7903 *) Added mod_unique_id which is used to generate a unique identifier for
7904 each hit, available in the environment variable UNIQUE_ID.
7907 *) init_modules is now called after the error logs have been opened. This
7908 allows modules to emit information messages into the error logs.
7911 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7912 information for case where proxy module is not available. [Marc Slemko]
7914 *) PORT: Apache has need for mutexes to serialize its children around
7915 accept. In prior versions either fcntl file locking or flock file
7916 locking were used. The method is chosen by the definition of
7917 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7918 and FLOCK for flock(). New options have been added:
7919 - SYSVSEM to use System V style semaphores
7920 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7921 - USLOCK to use IRIX uslock
7922 Based on timing various techniques, the following changes were made
7924 - Linux 2.x uses flock instead of fcntl
7925 - Solaris 2.x uses pthreads
7926 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7927 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7928 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7929 Martijn Koster <m.koster@pobox.com>]
7931 *) PORT: The semantics of accept/select make it very desirable to use
7932 mutexes to serialize accept when multiple Listens are in use. But
7933 in the case where only a single socket is open it is sometimes
7934 redundant to serialize accept(). Not all unixes do a good job with
7935 potentially dozens of children blocked on accept() on the same
7936 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7937 the server will avoid serialization when listening on only one socket,
7938 and use serialization when listening on multiple sockets.
7939 [Dean Gaudet] PR#467
7941 *) Configure changes: TestLib replaced by TestCompile, which has
7942 some additional capability (such as doing a sanity check of
7943 the compiler and flags selected); the version of Solaris is now
7944 available via the #define value of SOLARIS2; IRIX n32bit libs
7945 now supported and selectable by new Configuration Rule: IRIXN32;
7946 We no longer default to -O2 optimization. [Jim Jagielski]
7948 *) Updated Configure: Configuration now uses AddModule to specify
7949 module source or binary file location, relative to src directory.
7950 Modules can be dropped into modules/extra, or in their own
7951 directory, and modules can come with a Makefile or Configure can
7952 create one. Modules can add compiler or library information to
7953 generated Makefiles. [Paul Sutton]
7955 *) Source core re-organisation: distributed modules are now in
7956 modules/standard. All other source code is in main. OS-specific
7957 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7959 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7962 *) Fix another long-standing bug in sub_req_lookup_file where it would
7963 happily skip past access checks on subdirectories looked up with
7964 relative paths. (It's used by mod_dir, mod_negotiation,
7965 and mod_include.) [Dean Gaudet]
7967 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7968 N is the number of <Directory> sections, and M is the number of
7969 components in the filename of an object.
7971 To achieve this optimization the following config changes were made:
7972 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7973 <Files>s, and <Location>s now treat a slash as a special
7974 character. For example "/home/*/public_html" previously would
7975 match "/home/a/andrew/public_html", now it only matches things
7976 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7977 - It's possible now to use [] wildcarding in <Directory>, <Files>
7979 - Regex <Directory>s are applied after all non-regex <Directory>s.
7983 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7984 and corrupted paths. [Dean Gaudet]
7986 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7987 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7988 be accessed now via backreferences $1..$9 in RewriteConds test-against
7989 strings in addition to RewriteRules subst string. Second the grouped
7990 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7991 via backreferences %1..%9 both in following RewriteCond test-against
7992 strings and RewriteRules subst string. This provides maximum flexibility
7993 through the use of backreferences.
7994 Additionally the rewriting engine was cleaned up by putting common
7995 code to the new expand_backrefs_inbuffer() function.
7996 [Ralf S. Engelschall]
7998 *) When merging the main server's <Directory> and <Location> sections into
7999 a vhost, put the main server's first and the vhost's second. Otherwise
8000 the vhost can't override the main server. [Dean Gaudet] PR#717
8002 *) The <Directory> code would merge and re-merge the same section after
8003 a match was found, possibly causing problems with some modules.
8006 *) ip-based vhosts are stored and queried using a hashing function, which
8007 has been shown to improve performance on servers with many ip-vhosts.
8008 Some other changes had to be made to accommodate this:
8009 - the * address for vhosts now behaves like _default_
8010 - the matching process now is:
8011 - match an ip-vhost directly via hash (possibly matches main
8013 - if that fails, just pretend it matched the main server
8014 - if so far only the main server has been matched, perform
8015 name-based lookups (ServerName, ServerAlias, ServerPath)
8016 *only on name-based vhosts*
8017 - if they fail, look for _default_ vhosts
8018 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
8020 *) dbmmanage overhaul:
8021 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
8022 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
8023 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
8024 - provide better seed for rand
8025 - prompt for password as per getpass(3) (turn off echo, read from
8027 - use "newstyle" crypt based on $Config{osname} ($^O)
8028 - will not add a user if already in database, use new `update' command
8030 - added `check' command to check a users' password
8031 - added `import' command to convert existing password text-files or
8032 dbm files exported with `view'
8033 - more descriptive usage, general cleanup, 'use strict' clean, etc.
8036 *) Added psocket() which is a pool form of socket(), various places within
8037 the proxy weren't properly blocking alarms while registering the cleanup
8038 for its sockets. bclose() now uses pclose() and pclosesocket(). There
8039 was a bug where the client socket was being close()d twice due a still
8040 registered cleanup. [Dean Gaudet]
8042 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
8045 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
8046 [Jason Venner <jason@idiom.com>] PR#667
8048 *) Enable ``=""'' for RewriteCond directives to match against
8049 the empty string. This is the preferred way instead of ``^$''.
8050 [Ralf S. Engelschall]
8052 *) Fixed an infinite loop in mod_imap for references above the server root
8053 [Dean Gaudet] PR#748
8055 *) mod_proxy now has a ReceiveBufferSize directive, similar to
8056 SendBufferSize, so that the TCP window can be set appropriately
8057 for LFNs. [Phillip A. Prindeville]
8059 *) mod_browser has been replaced by the more general mod_setenvif
8060 (courtesy of Paul Sutton). BrowserMatch* directives are still
8061 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
8062 UnSetEnvIfZero directives. [Ken Coar]
8064 *) "HostnameLookups double" forces double-reverse DNS to succeed in
8065 order for remote_host to be set (for logging, or for the env var
8066 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
8069 *) mod_access overhaul:
8070 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
8071 and cidr syntax (i.e. 10.1.0.0/16). PR#762
8072 - Critical path was sped up by pre-computing a few things at config time.
8073 - The undocumented syntax "allow user-agents" was removed,
8074 the replacement is "allow from env=foobar" combined with mod_browser.
8075 - When used with hostnames it now forces a double-reverse lookup
8076 no matter what the directory settings are. This double-reverse
8077 doesn't affect any of the other routines that use the remote
8078 hostname. In particular it's still passed to CGIs and the log
8079 without the double-reverse check. Related PR#860.
8082 *) When a large bwrite() occurs (larger than the internal buffer size),
8083 while there is already something in the buffer, apache will combine
8084 the large write and the buffer into a single writev(). (This is
8085 in anticipation of using mmap() for reading files.)
8088 *) In obscure cases where a partial socket write occurred while chunking,
8089 Apache would omit the chunk header/footer on the next block. Cleaned
8090 up other bugs/inconsistencies in error conditions in buff.c. Fixed
8091 a bug where a long pause in DNS lookups could cause the last packet
8092 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
8094 *) API: Added child_exit function to module structure. This is called
8095 once per "heavy-weight process" just before a server child exit()'s
8096 e.g. when max_requests_per_child is reached, etc.
8097 [Doug MacEachern, Dean Gaudet]
8099 *) mod_include cleanup showed that handle_else was being used to handle
8100 endif. It didn't cause problems, but it was cleaned up too.
8103 *) mod_cern_meta would attempt to find meta files for the directory itself
8104 in some cases, but not in others. It now avoids it in all cases.
8107 *) mod_mime_magic would core dump if there was a decompression error.
8108 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
8110 *) PORT: some variants of DGUX require -lsocket -lnsl
8111 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
8113 *) mod_autoindex now allows sorting of FancyIndexed directory listings
8114 by the various fields (name, size, et cetera), either in ascending
8115 or descending order. Just click on the column header. [Ken Coar]
8117 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
8118 CPUs like the Alpha. Apache still stores ints in pointers, but that's
8119 the relatively safe direction. [Dean Gaudet] PR#344
8121 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
8122 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
8124 *) child_main avoids an unneeded call to select() when there is only one
8125 listening socket. [Dean Gaudet]
8127 *) In the event that the server is starved for idle servers it will
8128 spawn 1, then 2, then 4, ..., then 32 servers each second,
8129 doubling each second. It'll also give a warning in the errorlog
8130 since the most common reason for this is a poor StartServers
8131 setting. The define MAX_SPAWN_RATE can be used to raise/lower
8132 the maximum. [Dean Gaudet]
8134 *) Apache now provides an effectively unbuffered connection for
8135 CGI scripts. This means that data will be sent to the client
8136 as soon as the CGI pauses or stops output; previously, Apache would
8137 buffer the output up to a fixed buffer size before sending, which
8138 could result in the user viewing an empty page until the CGI finished
8139 or output a complete buffer. It is no longer necessary to use an
8140 "nph-" CGI to get unbuffered output. Given that most CGIs are written
8141 in a language that by default does buffering (e.g. perl) this
8142 shouldn't have a detrimental effect on performance.
8144 "nph-" CGIs, which formerly provided a direct socket to the client
8145 without any server post-processing, were not fully compatible with
8146 HTTP/1.1 or SSL support. As such they would have had to implement
8147 the transport details, such as encryption or chunking, in order
8148 to work properly in certain situations. Now, the only difference
8149 between nph and non-nph scripts is "non-parsed headers".
8150 [Dean Gaudet, Sameer Parekh, Roy Fielding]
8152 *) If a BUFF is switched from buffered to unbuffered reading the first
8153 bread() will return whatever remained in the buffer prior to the
8154 switch. [Dean Gaudet]
8156 Changes with Apache 1.3a1
8158 *) Added another Configure helper script: TestLib. It determines
8159 if a specified library exists. [Jim Jagielski]
8161 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8162 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8165 *) PORT: Some architectures use size_t for various lengths in network
8166 functions such as accept(), and getsockname(). The definition
8167 NET_SIZE_T is used to control this. [Dean Gaudet]
8169 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8170 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8171 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8173 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8174 [Igor N Kovalenko <infoh@mail.wplus.net>]
8176 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8177 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8178 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8179 [Dean Gaudet] related PR#875
8181 *) API: Correct child_init() slot declaration from int to void, to
8182 match the init() declaration. Update mod_example to use the new
8185 *) added transport handle slot (t_handle) to the BUFF structure
8188 *) get_client_block() returns wrong length if policy is
8189 REQUEST_CHUNKED_DECHUNK.

8199 *) AddModuleInfo directive for mod_info which allows you to annotate
8200 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8202 *) Added NoProxy directive to avoid using ProxyRemote for selected
8203 addresses. Added ProxyDomain directive to cause unqualified
8204 names to be qualified by redirection.
8205 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8207 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8208 header to the remote host in the proxy. [Sameer Parekh and
8211 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8212 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8213 URLs, fixed rewritelog(), fixed forced response code handling on
8214 redirects from within .htaccess files, disabled pipe locking under
8215 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8216 no substitution, bugfixed situations where HostnameLookups is off, made
8217 mod_rewrite more thread-safe for NT port and fixed problem when creating
8218 an empty query string via "xxx?".
8219 This update also removes the copyright of Ralf S. Engelschall,
8220 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8221 exclusively copyrighted by the Apache Group now. This happened because
8222 the author now has gifted mod_rewrite exclusively to the Apache Group and
8223 no longer maintains an external version.
8224 [Ralf S. Engelschall]
8226 *) API: Added child_init function to module structure. This is called
8227 once per "heavy-weight process" before any requests are handled.
8228 See http_config.h for more details. [Dean Gaudet]
8230 *) Anonymous_LogEmail was logging on each subrequest.
8231 [Dean Gaudet] PR#421, 868
8233 *) API: Added is_initial_req() which tests if the request being
8234 processed is the initial request, or a subrequest.
8237 *) Extended SSI (mod_include) now handles additional relops for
8238 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8240 *) Configure fixed to correctly propagate user-selected options and
8241 settings (such as CC and OPTIM) to Makefiles other than
8242 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8244 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8245 directory indices to start with the contents of the HeaderName file
8246 if there is one. If there isn't one, the behaviour is unchanged.
8247 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8249 *) WIN32: Modules can now be dynamically loaded DLLs using the
8250 LoadModule/LoadFile directives. Note that module DLLs must be
8251 compiled with the multithreaded DLL version of the runtime library.
8252 [Alexei Kosut and Ben Laurie]
8254 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8255 This allows the admin to completely remove automatic indexing
8256 from the server, while still supporting the basic functions of
8257 trailing-slash redirects and DirectoryIndex files. Note that if
8258 you're carrying over an old Configuration file and you use directory
8259 indexing then you'll want to add:
8261 Module autoindex_module mod_autoindex.o
8263 before mod_dir in your Configuration. [Dean Gaudet]
8265 *) popendir/pclosedir created to properly protect directory scanning.
8266 [Dean Gaudet] PR#525
8268 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8269 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8270 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8273 *) The AccessFileName directive can now take more than one filename.
8274 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8276 *) The new mod_mime_magic can be used to "magically" determine the type
8277 of a file if the extension is unknown. Based on the unix file(1)
8278 command. [Ian Kluft <ikluft@cisco.com>]
8280 *) We now determine and display the time spent processing a
8281 request if desired. [Jim Jagielski]
8283 *) mod_status: PID field of "dead" child slots no longer displays
8284 main httpd process's PID. [Jim Jagielski]
8286 *) Makefile.nt added - to build all the bits from the command line:
8287 nmake -f Makefile.nt
8288 Doesn't yet work properly. [Ben Laurie]
8290 *) Default text of 404 error is now "Not Found" rather than the
8291 potentially misleading "File Not Found". [Ken Coar]
8293 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8294 for the net if we require people that actually need this data to
8295 enable it. [Linus Torvalds]
8297 *) directory_walk() is an expensive function, keep a little more state to
8298 avoid needless string counting. Add two new functions make_dirstr_parent
8299 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8300 The new functions are a little less general than make_dirstr, but
8301 work more efficiently (less memory, less string counting).
8304 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8305 to LDFLAGS) to avoid complications with lex rules in make files.
8306 [Dean Gaudet] PR#372
8308 *) run_method optimized to avoid needless scanning over NULLs in the
8309 module list. [Dean Gaudet]
8311 *) Revamp of (unix) scoreboard management code such that it avoids
8312 unnecessary traversals of the scoreboard on each hit. This is
8313 particularly important for high volume sites with a large
8314 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8315 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8316 httpd.h. [Dean Gaudet]
8318 *) In configurations using multiple Listen statements it was possible for
8319 busy sockets to starve other sockets of service. [Dean Gaudet]
8321 *) Added hook so standalone_main can be replaced at compile time
8322 (define STANDALONE_MAIN)
8325 *) Lowest-level read/write functions in buff.c will be replaced with
8326 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8327 compile time. The default sfio discipline will behave as apache
8328 would without sfio compiled in.
8331 *) Enhance UserDir directive (mod_userdir) to accept a list of
8332 usernames for the 'disable' keyword, and add 'enable user...' to
8333 selectively *en*able userdirs if they're globally disabled.
8336 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8337 will work with Netscape dbm files. (dbmmanage will probably not
8338 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8340 *) Add a ListenBacklog directive to control the backlog parameter
8341 passed to listen(). Also change the default to 511 from 512.
8344 *) API: A new handler response DONE which informs apache that the
8345 request has been handled and it can finish off quickly, similar to
8346 how it handles errors. [Rob Hartill]
8348 *) Turn off chunked encoding after sending terminating chunk/footer
8349 so that we can't do it twice by accident. [Roy Fielding]
8351 *) mod_expire also issues Cache-Control: max-age headers.
8354 *) API: Added kill_only_once option for free_proc_chain so that it won't
8355 aggressively try to kill off specific children. For fastcgi.
8356 [Stanley Gambarin <gambarin@OpenMarket.com>]
8358 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8360 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8361 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8362 attributes in the FancyIndexing IMG tags. [Ken Coar]
8364 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8366 *) PORT: Added Windows NT support
8367 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8369 Changes with Apache 1.2.6
8371 *) mod_include when using XBitHack Full would send ETags in addition to
8372 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.

8375 *) SECURITY: When a client connects to a particular port/addr, and
8376 gives a Host: header ensure that the virtual host requested can
8377 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8379 *) Support virtual hosts with wildcard port and/or multiple ports
8380 properly. [Ed Korthof <ed@organic.com>]
8382 *) Fixed some case-sensitivity issues according to RFC2068.
8385 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8386 and mod_include.c. [Dean Gaudet]
8388 *) Variable 'cwd' was being used pointlessly before being set.
8391 *) SIGURG doesn't exist on all platforms.
8392 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8394 *) When an error occurs during a POST, or other operation with a

8398 *) When an error occurs in fcntl() locking suggest the user look up
8399 the docs for LockFile. [Dean Gaudet]
8401 *) table_set() and table_unset() did not deal correctly with
8402 multiple occurrences of the same key. [Stephen Scheck
8403 <sscheck@infonex.net>, Ben Laurie] PR#1604
8405 *) send_fd_length() did not calculate total_bytes_sent properly in error
8406 cases. [Ben Reser <breser@regnow.com>] PR#1366
8408 *) r->connection->user was allocated in the wrong pool causing corruption
8409 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8411 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8412 Also removed the auto-generated link to www.apache.org that was the
8413 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8415 *) Multiple "close" tokens may have been set in the "Connection"
8416 header, not an error, but a waste.
8417 [Ronald.Tschalaer@psi.ch] PR#1683
8419 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8420 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666

8423 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8424 at the 256th byte as well. Fixed. [Dean Gaudet]
8426 *) mod_rewrite would not handle %3f properly in some situations.
8429 *) Apache could generate improperly chunked HTTP/1.1 responses when
8430 the bputc() or rputc() functions were used by modules (such as
8431 mod_include). [Dean Gaudet]
8433 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8434 some ports. [Ralf Engelschall]
8436 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8438 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8440 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8442 Changes with Apache 1.2.5
8444 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8445 only an issue on systems without a MAXDNAME define or where
8446 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8448 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8451 *) Fix core dump in the ftp proxy when reading incorrectly formatted

8454 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8457 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8458 is used to read various types of files such as htaccess and
8459 htpasswd files. [Marc Slemko]
8461 *) SECURITY: Ensure that the buffer returned by ht_time is always
8462 properly null terminated. [Marc Slemko]
8464 *) SECURITY: General mod_include cleanup, including fixing several
8465 possible buffer overflows and a possible infinite loop. This cleanup
8466 was done against 1.3 code and then backported to 1.2, the result
8467 is a large difference (due to indentation cleanup in 1.3 code).
8468 Users interested in seeing a smaller set of relevant differences
8469 should consider comparing against src/modules/standard/mod_include.c
8470 from the 1.3b3 release. Non-indentation changes to mod_include
8471 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8473 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8474 including fixing a possible buffer overflow. This cleanup also
8475 was done with 1.3 code as a basis, see the the previous note
8476 about mod_include. [Dean Gaudet]
8478 *) SECURITY: If a htaccess file can not be read due to bad
8479 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8480 The previous behavior was to ignore the htaccess file if it could not
8481 be read. This change may make some setups with unreadable
8482 htaccess files stop working. PR#817 [Marc Slemko]

8514 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8515 always making requests with the full-URI instead of just the URI path.
8516 [Marc Slemko, Roy Fielding]
8518 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8519 on this platform. [Marc Slemko]
8521 Changes with Apache 1.2.3
8523 *) The request to a remote proxy was mangled if it was generated as the
8524 result of a ProxyPass directive. URL schemes other than http:// were not
8525 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
8526 PR#812 [Lars Eilebrecht]
8528 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8529 information for case where proxy module is not available. [Marc Slemko]
8531 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8532 do for errors and cached responses. [Roy Fielding]
8534 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8536 Changes with Apache 1.2.2 [not released]
8538 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8539 happily skip past access checks on subdirectories looked up with relative
8540 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8543 *) Add lockfile name to error message printed out when
8544 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8547 *) Enhanced the chunking and error handling inside the buffer functions.
8548 [Dean Gaudet, Roy Fielding]
8550 *) When merging the main server's <Directory> and <Location> sections into
8551 a vhost, put the main server's first and the vhost's second. Otherwise
8552 the vhost can't override the main server. [Dean Gaudet] PR#717
8554 *) The <Directory> code would merge and re-merge the same section after
8555 a match was found, possibly causing problems with some modules.
8558 *) Fixed an infinite loop in mod_imap for references above the server root.
8559 [Dean Gaudet] PR#748
8561 *) mod_include cleanup showed that handle_else was being used to handle
8562 endif. It didn't cause problems, but it was cleaned up too.
8565 *) Last official synchronization of mod_rewrite with author version (because
8566 mod_rewrite is now directly developed by the author at the Apache Group):
8567 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8568 minus WIN32/NT stuff, but plus copyright removement.
8570 - workaround for detecting infinite rewriting loops
8571 - fixed setting of env vars when "-" is used as subst string
8572 - fixed forced response code on redirects (PR#777)
8573 - fixed cases where r->args is ""
8574 - kludge to disable locking on pipes under braindead SunOS
8575 - fix for rewritelog in cases where remote hostname is unknown
8576 - fixed totally damaged request_rec walk-back loop
8577 o remove static from local data and add static to global ones.
8578 o replaced ugly proxy finding stuff by simple
8579 find_linked_module("mod_proxy") call.
8580 o added missing negation char on rewritelog()
8581 o fixed a few comment typos
8582 [Ralf S. Engelschall]
8584 *) Anonymous_LogEmail was logging on each subrequest.
8585 [Dean Gaudet] PR#421, PR#868
8587 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8588 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8589 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8590 Additionally mod_browser now triggers during translate_name to workaround
8591 a deficiency in the header_parse phase.

8598 *) Properly treat <files> container like other containers in mod_info.
8599 [Marc Slemko] PR#848
8601 *) The proxy didn't treat the "Host:" keyword of the host header as case-
8602 insensitive. The proxy would corrupt the first line of a response from
8603 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
8605 *) mod_include would log some bogus values occasionally.
8606 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
8608 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
8609 under Solaris 2.x (up through 2.5.1). It has been fixed.
8610 [Dean Gaudet] PR#832
8612 *) API: In HTTP/1.1, whether or not a request message contains a body
8613 is independent of the request method and based solely on the presence
8614 of a Content-Length or Transfer-Encoding. Therefore, our default
8615 handlers need to be prepared to read a body even if they don't know
8616 what to do with it; otherwise, the body would be mistaken for the
8617 next request on a persistent connection. discard_request_body()
8618 has been added to take care of that. [Roy Fielding] PR#378
8620 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
8621 release version number, such that it always increases along the
8622 same lines as our source code branching. [Roy Fielding]
8624 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
8626 Changes with Apache 1.2.1
8628 *) SECURITY: Don't serve file system objects unless they are plain files,
8629 symlinks, or directories. This prevents local users from using pipes
8630 or named sockets to invoke programs for an extremely crude form of
8633 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
8634 could contain "../" allowing a local user to "publish" any file on
8635 the system. No slashes are allowed now. [Dean Gaudet]
8637 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8638 (headers, readmes, titles), mod_negotiation (type maps), or
8639 mod_cern_meta (meta files). [Dean Gaudet]
8641 *) SECURITY: Apache will refuse to run as "User root" unless
8642 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8644 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8645 if it contained a .htaccess disallowing symlinks. This is contrary
8646 to the rule that symlink permissions are tested with the symlink
8647 options of the parent directory. [Dean Gaudet] PR#353
8649 *) CONFIG: The LockFile directive can be used to place the serializing
8650 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8651 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8654 *) Request processing now retains state of whether or not the request
8655 body has been read, so that internal redirects and subrequests will
8656 not try to read it twice (and block). [Roy Fielding]
8658 *) Add a placeholder in modules/Makefile to avoid errors with certain
8659 makes. [Marc Slemko]
8661 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
8662 [Dean Gaudet] PR#644
8664 *) mod_include was not properly changing the current directory.
8665 [Marc Slemko] PR#742
8667 *) Attempt to work around problems with third party libraries that do not
8668 handle high numbered descriptors (examples include bind, and
8669 solaris libc). On all systems apache attempts to keep all permanent
8670 descriptors above 15 (called the low slack line). Solaris users
8671 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8672 which keeps all non-FILE * descriptors above 255. On all systems
8673 this should make supporting large numbers of vhosts with many open
8674 log files more feasible. If this causes trouble please report it,
8675 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8676 [Dean Gaudet] various PRs
8678 *) Related to the last entry, network sockets are now opened before
8679 log files are opened. The only known case where this can cause
8680 problems is under Solaris with many virtualhosts and many Listen
8681 directives. But using -DHIGH_SLACK_LINE=256 described above will
8682 work around this problem. [Dean Gaudet]
8684 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8687 *) Improved unix error response logging. [Marc Slemko]
8689 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8690 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8691 when a URL http://... was used in conjunction with a special
8692 redirect flag, e.g. R=permanent, the permanent status was lost.

8696 would prefer the last listed variant rather than the first.

8727 Changes with Apache 1.2
8729 Changes with Apache 1.2b11
8731 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
8733 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
8734 [Doug MacEachern, Rob Hartill]
8736 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
8737 reading from one buffer and writing to another, at least until it has
8738 a custom timeout handler. [Roy Fielding and Petr Lampa]
8740 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
8741 apparently due to a mismatch between sigaction and setjmp.
8742 [Roy Fielding] PR#502
8744 *) Log correct status code if we timeout before receiving a request (408)
8745 or if we received a request-line that was too long to process (414).
8746 [Ed Korthof and Roy Fielding] PR#601
8748 *) Virtual hosts with the same ServerName, but on different ports, were
8749 not being selected properly. [Ed Korthof]
8751 *) Added code to return the requested IP address from proxy_host2addr()
8752 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
8753 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8754 [Chuck Murcko] PR#614
8756 *) If multiple requests on a single connection are used to retrieve
8757 data from different virtual hosts, the virtual host list would be
8758 scanned starting with the most recently used VH instead of the first,
8759 causing most virtual hosts to be ignored.
8760 [Paul Sutton and Martin Mares] PR#610
8762 *) The OS/2 handling of process group was broken by a porting patch for
8763 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
8765 *) Inherit virtual server port from main server if none (or "*") is
8766 given for VirtualHost. [Dean Gaudet] PR#576
8768 *) If the lookup for a DirectoryIndex name with content negotiation
8769 has found matching variants, but none are acceptable, return the
8770 negotiation result if there are no more DirectoryIndex names to lookup.
8771 [Petr Lampa and Roy Fielding]
8773 *) If a soft_timeout occurs after keepalive is set, then the main child
8774 loop would try to read another request even though the connection
8775 has been aborted. [Roy Fielding]
8777 *) Configure changes: Allow for whitespace at the start of a
8778 Module declaration. Also, be more understanding about the
8779 CC=/OPTIM= format in Configuration. Finally, fix compiler
8780 flags if using HP-UX's cc compiler. [Jim Jagielski]
8782 *) Subrequests and internal redirects now inherit the_request from the
8783 original request-line. [Roy Fielding]
8785 *) Test for error conditions before creating output header fields, since
8786 we don't want the error message to include those fields. Likewise,
8787 reset the content_language(s) and content_encoding of the response
8788 before generating or redirecting to an error message, since the new
8789 message will have its own Content-* definitions. [Dean Gaudet]
8791 *) Restored the semantics of headers_out (headers sent only with 200..299
8792 and 304 responses) and err_headers_out (headers sent with all responses).
8793 Avoid the overhead of copying tables if err_headers_out is empty
8794 (the usual case). [Roy Fielding]
8796 *) Fixed a couple places where a check for the default Content-Type was
8797 not properly checking both the value configured by the DefaultType
8798 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8799 of DEFAULT_TYPE to match the documented default (text/plain).
8800 [Dean Gaudet] PR#506
8802 *) Escape the HTML-sensitive characters in the Request-URI that is
8803 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8805 *) Properly initialize the flock structures used by the mutex locking
8806 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8809 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8810 (and NCSA httpd) definition wherein it was the extra path info beyond
8811 the CGI script filename. The environment variable FILEPATH_INFO has
8812 been removed, and instead we supply the original REQUEST_URI to any
8813 script that wants to be Apache-specific and needs the real URI path.
8814 This solves a problem with existing scripts that use extra path info
8815 in the ScriptAlias directive to pass options to the CGI script.
8818 *) The _default_ change in 1.2b10 will change the behaviour on configs
8819 that use multiple Listen statements for listening on multiple ports.
8820 But that change is necessary to make _default_ consistent with other
8821 forms of <VirtualHost>. It requires such configs to be modified
8822 to use <VirtualHost _default_:*>. The documentation has been
8823 updated. [Dean Gaudet] PR#530
8825 *) If an ErrorDocument CGI script is used to respond to an error
8826 generated by another CGI script which has already read the message
8827 body of the request, the server would block trying to read the
8828 message body again. [Rob Hartill]
8830 *) signal() replacement conflicted with a define on QNX (and potentially
8831 other platforms). Fixed. [Ben Laurie] PR#512
8833 Changes with Apache 1.2b10
8835 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8836 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8838 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8840 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
8842 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
8843 config, in case the hostent struct returned is trash.
8844 [Chuck Murcko] PR #491
8846 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8847 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8849 Changes with Apache 1.2b9 [never announced]
8851 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8852 changes and in anticipation of 1.2 final release. [Roy Fielding]
8854 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8855 the connection (e.g., when user presses Stop). Apache will now stop
8856 trying to send a message body immediately after an error from write.
8857 [Roy Fielding and Nathan Kurz] PR#335
8859 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8860 than mod_alias, and mod_alias has higher priority than mod_proxy;
8861 rearranged other modules to enhance understanding of their purpose
8862 and relative order (and maybe even reduce some overhead).
8863 [Roy Fielding and Sameer Parekh]
8865 *) Fix graceful restart. Eliminate many signal-related race
8866 conditions in both forms of restart, and in SIGTERM. See
8867 htdocs/manual/stopping.html for details on stopping and
8868 restarting the parent. [Dean Gaudet]
8870 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8871 memory allocator to avoid a behaviour that required extra blocks to
8872 be allocated. [Dean Gaudet]
8874 *) Allow suexec to access files relative to current directory but not
8875 above. (Excluding leading / or any .. directory.) [Ken Coar]
8878 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8879 PR#367, 368, 354, 453
8881 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8882 while obtaining the /~user and save the username in a separate data
8883 area so that it won't be overwritten by the call to getgrgid(), and
8884 fix some misuse of the pool string allocation functions. Also fixes
8885 a general problem with parsing URL query info into args for CGI scripts.

8893 AuthDBAuthoritative. [Marc Slemko] PR#420
8895 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8897 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8898 object that can't be PUT, or FOOBAR for some method FOOBAR that
8899 apache doesn't know about at all). Log 404s that occur in mod_include.
8900 [Paul Sutton, John Van Essen]
8902 *) If a soft timeout (or lingerout) occurs while trying to flush a
8903 buffer or write inside buff.c or fread'ing from a CGI's output,
8904 then the timeout would be ignored. [Roy Fielding] PR#373
8906 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8907 parsing of headers. If the terminating empty-line CRLF occurs starting
8908 at the 256th or 257th byte of output, then Navigator will think a normal
8909 image is invalid. We are guessing that this is because their initial
8910 read of a new request uses a 256 byte buffer. We check the bytes written
8911 so far and, if we are about to tickle the bug, we instead insert a
8912 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8914 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8915 of an external redirection. [Roy Fielding and Paul Sutton]
8917 *) Configure would create a broken Makefile if the configuration file
8918 contained a commented-out Rule. [Roy Fielding]
8920 *) Promote per_dir_config and subprocess_env from the subrequest to the
8921 main request in mod_negotiation. In particular this fixes a bug
8922 where <Files> sections wouldn't properly apply to negotiated content.
8925 *) Fix a potential deadlock in mod_cgi script_err handling.
8926 [Ralf S. Engelschall]
8928 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8931 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8932 .htaccess files because the RewriteBase was not replaced correctly.
8933 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8934 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8936 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8937 1.x the settings are those of pre-1.2b8. For 2.x we include
8938 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8939 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8940 [Dean Gaudet] PR#336, PR#340
8942 *) Redirect did not preserve ?query_strings when present in the client's
8943 request. [Dean Gaudet]
8945 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8947 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8949 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8951 *) Add mod_example (illustration of API techniques). [Ken Coar]
8953 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8955 *) Improve handling of directories when filenames have spaces in them.
8958 *) For hosts with multiple IP addresses, try all additional addresses if
8959 necessary to get a connect. Fail only if hostent address list is
8960 exhausted. [Chuck Murcko]
8962 *) More signed/unsigned port fixes. [Dean Gaudet]
8964 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8967 Changes with Apache 1.2b8
8969 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8970 to it. [Marc Slemko]
8972 *) The addition of <Location> and <File> directives made the
8973 sub_req_lookup_simple() function bogus, so we now handle
8974 the special cases directly. [Dean Gaudet]
8976 *) We now try to log where the server is dumping core when a fatal
8977 signal is received. [Ken Coar]
8979 *) Improved lingering_close by adding a special timeout, removing the
8980 spurious log messages, removing the nonblocking settings (they
8981 are not needed with the better timeout), and adding commentary
8982 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8983 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8985 *) Send error messages about setsockopt failures to the server error
8986 log instead of stderr. [Roy Fielding]
8988 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8990 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8991 processing a subrequest, allocate memory from r->main->pool instead
8992 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8993 in the middle of an SSI request. [Dean Gaudet] PR #122
8995 *) Fixed status of response when POST is received for a nonexistent URL
8996 (was sending 405, now 404) and when any method is sent with a
8997 full-URI that doesn't match the server and the server is not acting
8998 as a proxy (was sending 501, now 403). [Roy Fielding]
9000 *) Host port changed to unsigned short. [Ken Coar] PR #276
9002 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
9004 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
9006 *) Report extra info from errno with many errors that cause httpd to exit.
9007 spawn_child, popenf, and pclosef now have valid errno returns in the
9008 event of an error. Correct problems where errno was stomped on
9009 before being reported. [Dean Gaudet]
9011 *) In the proxy, if the cache filesystem was full, garbage_coll() was
9012 never called, and thus the filesystem would remain full indefinitely.
9013 We now also remove incomplete cache files left if the origin server
9014 didn't send a Content-Length header and either the client has aborted
9015 transfer or bwrite() to client has failed. [Petr Lampa]
9017 *) Fixed the handling of module and script-added header fields.
9018 Improved the interface for sending header fields and reduced
9019 the duplication of code between sending okay responses and errors.
9020 We now always send both headers_out and err_headers_out, and
9021 ensure that the server-reserved fields are not being overridden,
9022 while not overriding those that are not reserved. [Roy Fielding]
9024 *) Moved transparent content negotiation fields to err_headers_out
9025 to reflect above changes. [Petr Lampa]
9027 *) Fixed the determination of whether or not we should make the
9028 connection persistent for all of the cases where some other part
9029 of the server has already indicated that we should not. Also
9030 improved the ordering of the test so that chunked encoding will
9031 be set whenever it is desired instead of only when KeepAlive
9032 is enabled. Added persistent connection capability for most error
9033 responses (those that do not indicate a bad input stream) when
9034 accessed by an HTTP/1.1 client. [Roy Fielding]
9036 *) Added missing timeouts for sending header fields, error responses,
9037 and the last chunk of chunked encoding, each of which could have
9038 resulted in a process being stuck in write forever. Using soft_timeout
9039 requires that the sender check for an aborted connection rather than
9040 continuing after an EINTR. Timeouts that used to be initiated before
9041 send_http_header (and never killed) are now initiated only within or
9042 around the routines that actually do the sending, and not allowed to
9043 propagate above the caller. [Roy Fielding]
9045 *) mod_auth_anon required an @ or a . in the email address, not both.
9048 *) per_dir_defaults weren't set correctly until directory_walk for
9049 name-based vhosts. This fixes an obscure bug with the wrong config
9050 info being used for vhosts that share the same ip as the server.
9053 *) Improved generation of modules/Makefile to be more generic for
9054 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
9056 *) Generate makefile dependency for Configuration based on the actual
9057 name given when running the Configure process. [Dean Gaudet]
9059 *) Fixed problem with vhost error log not being set prior to
9060 initializing virtual hosts. [Dean Gaudet]
9062 *) Fixed infinite loop when a trailing slash is included after a type map
9063 file URL (extra path info). [Petr Lampa]
9065 *) Fixed server status updating of per-connection counters. [Roy Fielding]
9067 *) Add documentation for DNS issues (reliability and security), and try
9068 to explain the virtual host matching process. [Dean Gaudet]
9070 *) Try to continue gracefully by disabling the vhost if a DNS lookup
9071 fails while parsing the configuration file. [Dean Gaudet]
9073 *) Improved calls to setsockopt. [Roy Fielding]
9075 *) Negotiation changes: Don't output empty content-type in variant list;
9076 Output charset in variant list; Return sooner from handle_multi() if
9077 no variants found; Add handling of '*' wildcard in Accept-Charset.
9078 [Petr Lampa and Paul Sutton]
9080 *) Fixed overlaying of request/sub-request notes and headers in
9081 mod_negotiation. [Dean Gaudet]
9083 *) If two variants' charset quality are equal and one is the default
9084 charset (iso-8859-1), then prefer the variant that was specifically
9085 listed in Accept-Charset instead of the default. [Petr Lampa]
9087 *) Memory allocation problem in push_array() -- it would corrupt memory
9088 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
9090 *) invoke_handler() doesn't handle mime arguments in content-type
9093 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
9096 *) Fixed problem with ErrorDocument not working for virtual hosts
9097 due to one of the performance changes in 1.2b7. [Dean Gaudet]
9099 *) Log an error message if we get a request header that is too long,
9100 since it may indicate a buffer overflow attack. [Marc Slemko]
9102 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
9103 not reject URLs without a double-slash, as per RFC2068 section 3.2.
9104 [Ken Coar] PR #146, #187
9106 *) Added table entry placeholder for new header_parser callback
9107 in all of the distributed modules. [Ken Coar] PR #191
9109 *) Allow for cgi files without the .EXE extension on them under OS/2.
9110 [Garey Smiley] PR #59
9112 *) Fixed error message when resource is not found and URL contains
9113 path info. [Petr Lampa and Dean Gaudet] PR #40
9115 *) Fixed user and server confusion over what should be a virtual host
9116 and what is the main server, resulting in access to something
9117 other than the name defined in the virtualhost directive (but
9118 with the same IP address) failing. [Dean Gaudet]
9120 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
9121 AIX; improves the redirection stuff to enable the users to generally
9122 redirect to http, https, gopher and ftp; added TIME variable for
9123 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
9124 special patterns >STRING, <STRING and =STRING to RewriteCond, which
9125 can be used in conjunction with %{TIME} or other variables to create
9126 time-dependent rewriting rules. [Ralf S. Engelschall]
9128 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
9129 Module authors may need to adjust their code for proper cleanup to take
9130 place (that is, call note_cleanups_for_fd()). This change fixes problems
9131 with file descriptors being erroneously closed when the proxy module was
9132 in use. [Ben Laurie]
9134 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
9135 initgroups() to hose the group information needed for later
9136 comparisons. [Randy Terbush]
9138 *) Remove unnecessary call to va_end() in create_argv() which
9139 caused a SEGV on some systems.
9141 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
9144 *) Clear memory allocated for listeners. [Randy Terbush]
9146 *) Improved handling of IP address as a virtualhost address and
9147 introduced "_default_" as a synonym for the default vhost config.
9148 [Dean Gaudet] PR #212
9150 Changes with Apache 1.2b7
9152 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
9154 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
9156 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
9157 - replace protocol response numbers with symbols
9158 - save variant-list into main request notes
9159 - free allocated memory from subrequests
9160 - merge notes, headers_out and err_headers_out
9162 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
9163 "HTTP/#.# ###*" to be more lenient about what we accept.
9166 *) more proxy FTP bug fixes:
9167 - Changed send_dir() to remove user/passwd from displayed URL.
9168 - Changed login error messages to be more descriptive.
9169 - remove setting of SO_DEBUG socket option
9170 - Make ftp_getrc() more lenient about multiline responses,
9171 specifically, 230 responses which don't have continuation 230-
9172 on each line). These seem to be all NT FTP servers, and while
9173 perhaps questionable, they appear to be legal by RFC 959.
9174 - Add missing kill_timeout() after transfer to user completes.
9177 *) Fixed problem where a busy server could hang when restarting
9178 after being sent a SIGHUP due to child processes not exiting.
9181 *) Modify mod_include escaping so a '\' only signifies an escaped
9182 character if the next character is one that needs
9183 escaping. [Ben Laurie]
9185 *) Eliminated possible infinite loop in mod_imap when relative URLs are
9186 used with a 'base' directive that does not have a '/' in it.
9187 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
9189 *) Reduced the default timeout from 1200 seconds to 300, and the
9190 one in the sample configfile from 400 to 300. [Marc Slemko]
9192 *) Stop vbprintf from crashing if given a NULL string pointer;
9193 print (null) instead. [Ken Coar]
9195 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
9196 [Marc Slemko and Roy Fielding]
9198 *) Fixed problem with mod_cgi-generated internal redirects trying to
9199 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9201 *) Reduced timeout on lingering close, removed possibility of a blocked
9202 read causing the child to hang, and stopped logging of errors if
9203 the socket is not connected (reset by client). [Roy Fielding]
9205 *) Rearranged main child loop to remove duplication of code in
9206 select/accept and keep-alive requests, fixed several bugs regarding
9207 checking scoreboard_image for exit indication and failure to
9208 account for all success conditions and trap all error conditions,
9209 prevented multiple flushes before closing the socket; close the entire
9210 socket buffer instead of just one descriptor, prevent logging of
9211 EPROTO and ECONNABORTED on platforms where supported, and generally
9212 improved readability. [Roy Fielding]
9214 *) Extensive performance improvements. Cleaned up inefficient use of
9215 auto initializers, multiple is_matchexp calls on a static string,
9216 and excessive merging of response_code_strings. [Dean Gaudet]
9218 *) Added double-buffering to mod_include to improve performance on
9219 server-side includes. [Marc Slemko]
9221 *) Several fixes for suexec wrapper. [Randy Terbush]
9222 - Make wrapper work for files on NFS filesystem.
9223 - Fix portability problem of MAXPATHLEN.
9224 - Fix array overrun problem in clean_env().
9225 - Fix allocation of PATH environment variable
9227 *) Removed extraneous blank line is description of mod_status chars.
9230 *) Logging of errors from the call_exec routine simply went nowhere,
9231 since the logfile fd has been closed, so now we send them to stderr.
9232 [Harald T. Alvestrand]
9234 *) Fixed core dump when DocumentRoot is a CGI.
9235 [Ben Laurie, reported by geddis@tesserae.com]
9237 *) Fixed potential file descriptor leak in mod_asis; updated it and
9238 http_core to use pfopen/pfclose instead of fopen/fclose.
9239 [Randy Terbush and Roy Fielding]
9241 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9242 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9243 [Dean Gaudet and Ken Coar]
9245 *) Return a 302 response code to the client when sending a redirect
9246 due to a missing trailing '/' on a directory instead of a 301; now
9247 it is cacheable. [Markus Gyger]
9249 *) Fix condition where, if a bad directive occurs in .htaccess, and
9250 sub_request() goes first to this directory, then log_reason() will
9251 SIGSEGV because it doesn't have initialized r->per_dir_config.
9252 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9254 *) Fix handling of lang_index in is_variant_better(). This was
9255 causing problems which resulted in the server sending the
9256 wrong language document in some cases. [Petr Lampa]
9258 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9259 the clean environment on some systems.
9261 *) Tweak byteserving code (e.g. serving PDF files) to work around
9262 bugs in Netscape Navigator and Microsoft Internet Explorer.
9263 Emit Content-Length header when sending multipart/byteranges.
9266 *) Port to HI-UX/WE2. [Nick Maclaren]
9268 *) Port to HP MPE operating system for HP 3000 machines
9269 [Mark Bixby <markb@cccd.edu>]
9271 *) Fixed bug which caused a segmentation fault if only one argument
9272 given to RLimit* directives. [Ed Korthof]
9274 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9276 *) Improved buffered output to the client by delaying the flush decision
9277 until the BUFF code is actually about to read the next request.
9278 This fixes a problem introduced in 1.2b5 with clients that send
9279 an extra CRLF after a POST request. Also improved chunked output
9280 performance by combining writes using writev() and removing as
9281 many bflush() calls as possible. NOTE: Platforms without writev()
9282 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9283 or Configure, unless we have already done so. [Dean Gaudet]
9285 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9287 *) Fixed mod_info output corruption bug introduced by buffer overflow
9288 fixes. [Dean Gaudet]
9290 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9291 for the special case of a 304 response. [Paul Sutton]
9293 *) Improved handling of TRACE method by bypassing normal method handling
9294 and header parsing routines; fixed Allow response to always allow TRACE.
9297 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9299 *) Cleaned-up some of the generated HTML. [Ken Coar]
9301 Changes with Apache 1.2b6
9303 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9305 *) Fix typo introduced in fix for potential infinite loop around
9306 accept() in child_main(). This change caused the rev to 1.2b6.
9307 1.2b5 was never a public beta.
9309 Changes with Apache 1.2b5
9311 *) Change KeepAlive semantics (On|Off instead of a number), add
9312 MaxKeepAliveRequests directive. [Alexei Kosut]
9314 *) Various NeXT compilation patches, as well as a change in
9315 regex/regcomp.c since that file also used a NEXT define.
9318 *) Allow * to terminate the end of a directory match in mod_dir.
9319 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9321 *) Don't call can_exec() if suexec_enabled. Calling this requires
9322 scripts executed by the suexec wrapper to be world executable, which
9323 defeats one of the advantages of running the wrapper. [Randy Terbush]
9325 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9328 *) Migration from sprintf() to snprintf() to avoid buffer
9329 overflows. [Marc Slemko]
9331 *) Provide portable snprintf() implementation (ap_snprintf)
9332 as well as *cvt family. [Jim Jagielski]
9334 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9337 *) Remove mod_fastcgi.c from the distribution. This module appears
9338 to be maintained more through the Open Market channels and should
9339 continue to be easily available at http://www.fastcgi.com/
9341 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9342 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9344 *) mod_info assumed that the config files were relative to ServerRoot.
9347 *) CGI scripts called as an error document resulting from failed
9348 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9350 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9353 *) Properly check errno to prevent display of a directory index
9354 when server receives a long enough URL to confuse stat().
9357 *) Several security enhancements to suexec wrapper. It is _highly_
9358 recommended that previously installed versions of the wrapper
9359 be replaced with this version. [Randy Terbush, Jason Dour]
9361 - ~user execution now properly restricted to ~user's home
9362 directory and below.
9363 - execution restricted to UID/GID > 100
9364 - restrict passed environment to known variables
9365 - call setgid() before initgroups() (portability fix)
9366 - remove use of setenv() (portability fix)
9368 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9370 *) Add access control via environment variables. [Ben Laurie]
9372 *) Add rflush() function. [Alexei Kosut]
9374 *) remove duplicate pcalloc() call in new_connection().
9376 *) Fix incorrect comparison which could allow number of children =
9377 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9378 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9380 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9381 AIX PS/2, CONVEXOS. [Jim Jagielski]
9383 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9384 It's more portable. [Martin Kraemer]
9386 *) Replace references to make in Makefile.tmpl with $(MAKE).
9389 *) Add ProxyBlock directive w/IP address caching. Add IP address
9390 caching to NoCache directive as well. ProxyBlock works with all
9391 handlers; NoCache now also works with FTP for anonymous logins.
9392 Still more code cleanup. [Chuck Murcko]
9394 *) Add "header parse" API hook [Ben Laurie]
9396 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9398 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9400 *) Correctly allow access and auth directives in <Files> sections in
9401 server config files. [Alexei Kosut]
9403 *) Fix bug with ServerPath that could cause certain files to be not
9404 found by the server. [Alexei Kosut]
9406 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9407 double-quote from text and so that it properly checks for unsupported
9408 status codes using the new index_of_response interface. [Roy Fielding]
9410 *) Multiple fixes to the lingering_close code in order to avoid being
9411 interrupted by a stray timeout, to avoid lingering on a connection
9412 that has already been aborted or never really existed, to ensure that
9413 we stop lingering as soon as any error condition is received, and to
9414 prevent being stuck indefinitely if the read blocks. Also improves
9415 reporting of error conditions. [Marc Slemko and Roy Fielding]
9417 *) Fixed initialization of parameter structure for sigaction.
9418 [mgyger@itr.ch, Adrian Filipi-Martin]
9420 *) Fixed reinitializing the parameters before each call to accept and
9421 select, and removed potential for infinite loop in accept.
9422 [Roy Fielding, after useful PR from adrian@virginia.edu]
9424 *) Fixed condition where, if a child fails to fork, the scoreboard would
9425 continue to say SERVER_STARTING forever. Eventually, the main process
9426 would refuse to start new children because count_idle_servers() will
9427 count those SERVER_STARTING entries and will always report that there
9428 are enough idle servers. [Phillip Vandry]
9430 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9431 Avoided calling bflush() when the client is pipelining requests.
9432 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9434 *) Added description of "." mode in server-status [Jim Jagielski]
9436 Changes with Apache 1.2b4
9438 *) Fix possible race condition in accept_mutex_init() that
9439 could leave a small security hole open allowing files to be
9440 overwritten in cases where the server UID has write permissions.
9443 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9445 *) Fix portablity problem in util_script where ARG_MAX may not be
9446 defined for some systems.
9448 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9451 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9452 style magic #! token for better script portability. [Garey Smiley]
9454 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9455 execution for ~userdir CGI. [Jason Dour]
9457 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9459 *) Fix month off by one in suexec wrapper logging.
9461 Changes with Apache 1.2b3:
9463 *) Fix error in mod_cgi which could cause resources not to be properly
9464 freed, or worse. [Dean Gaudet]
9466 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9468 *) Add set_flag_slot() at the request of Dirk and others.
9471 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9473 *) Add changes to improve the error message given for invalid
9474 ServerName parameters. [Dirk vanGulik]
9476 *) Add "Authoritative" directive for Auth modules that don't
9477 currently have it. This gives admin control to assign authoritative
9478 control to an authentication scheme and allow "fall through" for
9479 those authentication modules that aren't "Authoritative" thereby
9480 allowing multiple authentication mechanisms to be chained.
9483 *) Remove requirement for ResourceConfig/AccessConfig if not using
9484 the three config file layout. [Randy Terbush]
9486 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9488 *) Changes to suexec wrapper to fix the following problems:
9489 1. symlinked homedirs will kill ~userdirs.
9490 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9491 3. CGI command lines paramters problems
9492 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9493 [Randy Terbush, Jason Dour]
9495 *) Change create_argv() to accept variable arguments. This fixes
9496 a problem where arguments were not getting passed to the CGI via
9497 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9499 *) Collapse multiple slashes in path URLs to properly apply
9500 handlers defined by <Location>. [Alexei Kosut]
9502 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9504 *) Improve the accuracy of request duration timings by setting
9505 r->request_time in read_request_line() instead of read_request().
9508 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9509 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9511 *) Add the ability to pass different Makefile.tmpl files to Configure
9512 using the -make flag. [Rob Hartill]
9514 *) Fix coredump triggered when sending a SIGHUP to the server caused
9515 by an assertion failure, in turn caused by an uninitialised field in a
9519 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9520 PATH_INFO from previous versions of Apache (in certain situations,
9521 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9522 [later removed in 1.2b11]
9524 *) Add rwrite() function to API to allow for sending strings of
9525 arbitrary length. [Doug MacEachern]
9527 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9529 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9530 NeXT. [Jim Jagielski]
9532 *) Removed recent modification to promote the status code on internal
9533 redirects, since the correct fix was to change the default log format
9534 in mod_log_config so that it outputs the original status. [Rob Hartill]
9536 Changes with Apache 1.2b2:
9538 *) Update set_signals() to use sigaction() for setting handlers.
9539 This appears to fix a re-entrant problem in the seg_fault()
9540 bus_error() handlers. [Randy Terbush]
9542 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9544 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9546 *) proxy_http.c bugfixes: [Chuck Murcko]
9547 1) fixes possible NULL pointer reference w/NoCache
9548 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9549 host would cache nothing if it was in the local domain,
9550 and the local domain was in the NoCache list)
9551 3) Adds Host: header when not available
9552 4) Some code cleanup and clarification
9554 *) mod_include.c bugfixes:
9555 1) Fixed an ommission that caused include variables to not
9556 be parsed in config errmsg directives [Howard Fear]
9557 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9558 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9559 4) Allow backslash-escaping to all quoted text
9560 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9561 5) Pass variable to command line if not set in XSSI's env
9564 *) Fix infinite loop when processing Content-language lines in
9565 type-map files. [Alexei Kosut]
9567 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9569 *) Fixed problem in set_[user|group] that prevented CGI execution
9570 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9572 *) Added PORTING information file. [Jim Jagielski]
9574 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9576 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9578 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9579 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9581 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9582 which caused problems of systems where socket s_addr is >32bits.
9584 *) Added comment to explain (r->chunked = 1) side-effect in
9585 http_protocol.c [Roy Fielding]
9587 *) Replaced use of index() in mod_expires.c with more appropriate
9588 and portable isdigit() test. [Ben Laurie]
9590 *) Updated Configure for ...
9591 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9592 *-dg-dgux* (bad pattern match)
9593 QNX (DEF_WANTHSREGEX=yes)
9594 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9597 and added some user diagnostic info. [Ben Laurie]
9599 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9600 for better portability. [Jim Jagielski]
9602 *) Updated helpers/GuessOS for ...
9603 SCO 5 (recognize minor releases)
9604 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9605 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9606 IRIX64 (-sgi-irix64)
9607 ULTRIX (-unknown-ultrix)
9608 SINIX (-whatever-sysv4)
9609 NCR Unix (-ncr-sysv4)
9610 and fixed something in helpers/PrintPath [Ben Laurie]
9612 Changes with Apache 1.2b1
9614 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9616 Changes with Apache 1.1.1
9618 *) Fixed bug where Cookie module would make two entries in the
9619 logfile for each access [Mark Cox]
9621 *) Fixed bug where Redirect in .htaccess files would cause memory
9622 leak. [Nathan Neulinger]
9624 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9626 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9628 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9630 Changes with Apache 1.1.0
9632 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9634 *) Bring QNX support up to date. [Ben Laurie]
9636 *) Make virtual hosts default to main server keepalive parameters.
9637 [Alexei Kosut, Ben Laurie]
9639 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9641 *) Fix missing address family for connect, also remove unreachable statement
9642 in mod_proxy. [Ben Laurie]
9644 *) mod_env now turned on by default in Configuration.tmpl.
9646 *) Bugs which were fixed:
9647 a) yet more mod_proxy bugs [Ben Laurie]
9648 b) CGI works again with inetd [Alexei Kosut]
9649 c) Leading colons were stripped from passwords [osm@interguide.com]
9650 d) Another fix to multi-method Limit problem [jk@tools.de]
9652 Changes with Apache 1.1b4
9654 *) r->bytes_sent variable restored. [Robert Thau]
9656 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9658 *) More possibly unsecure programs removed from the support directory.
9660 *) More mod_auth_msql authentication improvements.
9662 *) VirtualHosts based on Host: headers no longer conflict with the
9665 *) OS/2 compatibility enhancements. [Gary Smiley]
9667 *) POST now allowed to directory index CGI scripts.
9669 *) Actions now work with files of the default type.
9671 *) Bugs which were fixed:
9672 a) more mod_proxy bugs
9673 b) early termination of inetd requests
9674 c) compile warnings on several systems
9675 d) problems when scripts stop reading output early
9677 Changes with Apache 1.1b3
9679 *) Much of cgi-bin and all of cgi-src has been removed, due to
9680 various security holes found and that we could no longer support
9683 *) The "Set-Cookie" header is now special-cased to not merge multiple
9684 instances, since certain popular browsers can not handle multiple
9685 Set-Cookie instructions in a single header. [Paul Sutton]
9687 *) rprintf() added to buffer code, occurrences of sprintf removed.
9690 *) CONNECT method for proxy module, which means tunneling SSL should work.
9691 (No crypto needed) Also a NoCache config directive.
9693 *) Several API additions: pstrndup(), table_unset() and get_token()
9694 functions now available to modules.
9696 *) mod_imap fixups, in particular Location: headers are now complete
9699 *) New "info" module which reports on installed module set through a
9700 special URL, a la mod_status.
9702 *) "ServerPath" directive added - allows for graceful transition
9703 for Host:-header-based virtual hosts.
9705 *) Anonymous authentication module improvements.
9707 *) MSQL authentication module improvements.
9709 *) Status module design improved - output now table-based. [Ben Laurie]
9711 *) htdigest utility included for use with digest authentication
9714 *) mod_negotiation: Accept values with wildcards to be treated with
9715 less priority than those without wildcards at the same quality
9716 value. [Alexei Kosut]
9718 *) Bugs which were fixed:
9719 a) numerous mod_proxy bugs
9720 b) CGI early-termination bug [Ben Laurie]
9721 c) Keepalives not working with virtual hosts
9722 d) RefererIgnore problems
9723 e) closing fd's twice in mod_include (causing core dumps on
9724 Linux and elsewhere).
9726 Changes with Apache 1.1b2
9729 a) core dumps in mod_digest
9730 b) truncated hostnames/ip address in the logs
9731 c) relative URL's in mod_imap map files
9733 Changes with Apache 1.1b1
9735 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9737 Changes with Apache 1.0.3
9739 *) Internal redirects which occur in mod_dir.c now preserve the
9740 query portion of a request (the bit after the question mark).
9743 *) Escape active characters '<', '>' and '&' in html output in
9744 directory listings, error messages and redirection links.
9747 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9749 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9752 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9754 *) Reset timeout timer after each successful fwrite() to the network.
9755 This patch adds a reset_timeout() procedure that is called by
9756 send_fd() to reset the timeout ever time data is written to the net.
9759 *) timeout() signal handler now checks for SIGPIPE and reports
9760 lost connections in a more user friendly way. [Rob Hartill]
9762 *) Location of the "scoreboard" file which used to live in /tmp is
9763 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9764 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9766 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9768 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9769 which caused a SEGV with cookies enabled
9771 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9774 *) Log the UNIX textual error returned by some system calls, in
9775 particular errors from accept() [David Robinson]
9777 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9779 Changes with Apache 1.0.2
9781 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9782 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9784 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9787 *) past changes to http_config.c to only use the
9788 setrlimit function on systems defining RLIMIT_NOFILE
9789 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9790 for SUNOS and prototypes the needed functions.
9792 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9795 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9797 *) Merge multiple headers from CGI scripts instead of taking last
9798 one. [David Robinson]
9800 *) Add support for SCO 5. [Ben Laurie]
9802 Changes with Apache 1.0.1
9804 *) Silence mod_log_referer and mod_log_agent if not configured
9807 *) Recursive includes can occur if the client supplies PATH_INFO data
9808 and the server provider uses relative links; as file.html
9809 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9811 *) The replacement for initgroups() did not call {set,end}grent(). This
9812 had two implications: if anything else used getgrent(), then
9813 initgroups() would fail, and it was consuming a file descriptor.
9816 *) On heavily loaded servers it was possible for the scoreboard to get
9817 out of sync with reality, as a result of a race condition.
9818 The observed symptoms are far more Apaches running than should
9819 be, and heavy system loads, generally followed by catastrophic
9820 system failure. [Ben Laurie]
9822 *) Fix typo in license. [David Robinson]
9824 Changes with Apache 1.0.0 23 Nov 1995
9826 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9828 Changes with Apache 0.8.16 05 Nov 1995
9830 *) New man page for 'httpd' added to support directory [David Robinson]
9832 *) .htgroup files can have more than one line giving members for a
9833 given group (each must have the group name in front), for NCSA
9834 back-compatibility [Robert Thau]
9836 *) Mutual exclusion around accept() is on by default for SVR4 systems
9837 generally, since they generally can't handle multiple processes in
9838 accept() on the same socket. This should cure flaky behavior on
9839 a lot of those systems. [David Robinson]
9841 *) AddType, AddEncoding, and AddLanguage directives take multiple
9842 extensions on a single command line [David Robinson]
9844 *) UserDir can be disabled for a given virtual host by saying
9845 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9846 that this didn't work. [David Robinson]
9848 *) Compiles on QNX [Ben Laurie]
9850 *) Corrected parsing of ctime time format [David Robinson]
9852 *) httpd does a perror() before exiting if it can't log its pid
9853 to the PidFile, to make diagnosing the error a bit easier.
9856 *) <!--#include file="..."--> can no longer include files in the
9857 parent directory, for NCSA back-compatibility. [David Robinson]
9859 *) '~' is *not* escaped in URIs generated for directory listings
9862 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9864 *) Fixed bug involving handling URIs with escaped %-characters
9865 in redirects [David Robinson]
9867 Changes with Apache 0.8.15 14 Oct 1995
9869 *) Switched to new, simpler license
9871 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9873 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9875 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9877 *) Correctly handles internal redirects to files with names containing '%'
9880 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9882 *) Use geteuid() rather than getuid() to see if we have root privilege,
9883 so that server correctly resets privilege if run setuid root. [Andrew
9886 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9889 *) Fix relative URLs in imagemap files [Randy Terbush]
9891 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9894 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9895 entries all name the same one. [David Robinson]
9897 *) Fix directory listings with filenames containing unusual characters
9900 *) Better URI-escaping for generated URIs in directories with filenames
9901 containing unusual characters [Ben Laurie]
9903 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9905 *) Unblock alarms on error return from spawn_child() [David Robinson]
9907 *) Sample Config files have extra note for SCO users [Ben Laurie]
9909 *) Configuration has note for HP-UX users [Rob Hartill]
9911 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9913 *) Nuked bogus #define in httpd.h [David Robinson]
9915 *) Better test for whether a system has setrlimit() [David Robinson]
9917 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9919 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9922 Changes with Apache 0.8.14 19 Sep 1995
9924 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9926 *) AddDescription works (better) [Ben Laurie]
9928 *) Leaves an intelligible error diagnostic when it can't set group
9929 privileges on standalone startup [Andrew Wilson]
9931 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9932 that machine, which claims to be BSD but does not support RLIMIT.
9935 *) gcc -Wall no longer complains about an unused variable when util.c
9936 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9938 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9940 Changes with Apache 0.8.13 07 Sep 1995
9942 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9944 *) Have built-in imagemap code recognize & honor Point directive [James
9947 *) Generate cleaner directory listings in directories with a mix of
9948 long and short filenames [Rob Hartill]
9950 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9952 *) Properly default ServerName for virtual servers [Robert Thau]
9954 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9955 Paul Richards and a cast of thousands...]
9957 *) On self-identified BSD systems (we don't try to guess any more),
9958 allocate a few extra file descriptors per virtual host with setrlimit,
9959 if we can, to avoid running out. [Randy Terbush]
9961 *) Write 22-character lock file name into buffer with enough space
9962 on startup [Konstantin Olchanski]
9964 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9967 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9969 *) Suppress -Wall warning by initializing variable in negotiation code
9970 [Tobias Weingartner]
9972 Changes with Apache 0.8.12 31 Aug 1995
9974 *) Doesn't pause three seconds after including a CGI script which is
9975 too slow to die off (this is done by not even trying to kill off
9976 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9977 after the entire document has been processed). [Robert Thau]
9979 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9981 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9983 *) Allows .htaccess files to override <Directory> sections naming the
9984 same directory [David Robinson]
9986 *) Removed an efficiency hack in sub_req_lookup_uri which was
9987 causing certain extremely marginal cases (e.g., ScriptAlias of a
9988 *particular* index.html file) to fail. [David Robinson]
9990 *) Doesn't log an error when the requested URI requires
9991 authentication, but no auth header line was supplied by the
9992 client; this is a normal condition (the client doesn't no auth is
9993 needed here yet). [Robert Thau]
9995 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9997 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9999 *) RFC931 code no longer passes out name of prior clients on current
10000 requests if the current request came from a server that doesn't
10001 do RFC931. [David Robinson]
10003 *) Configuration script accepts "Module" lines with trailing whitespace.
10006 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
10008 *) Cleaned up comments in mod_cgi.c [Robert Thau]
10010 Changes with Apache 0.8.11 24 Aug 1995
10012 *) Wildcard <Directory> specifications work. [Robert Thau]
10014 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
10016 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
10017 the file being requested itself, in addition to the directories leading
10018 up to it. [Robert Thau]
10020 *) Logs access failures due to symlink checks or invalid client address
10021 in the error log [Roy Fielding, Robert Thau]
10023 *) Symlink checks deal correctly with systems where lstat of
10024 "/path/to/some/link/" follows the link. [Thau, Fielding]
10026 *) Doesn't reset DirectoryIndex to 'index.html' when
10027 other directory options are set in a .htaccess file. [Robert Thau]
10029 *) Clarified init code and nuked bogus warning in mod_access.c
10030 [Florent Guillaume]
10032 *) Corrected several directives in sample srm.conf
10033 --- includes corrections to directory indexing icon-related directives
10034 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
10035 icons for encodings right, and turning on AddEncoding by default).
10038 *) Corrected descriptions of args to AddIcon and AddAlt in command table
10041 *) INSTALL & README mention "contributed modules" directory [Brian
10044 *) Fixed English in the license language... "for for" --> "for".
10047 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
10048 mod_alias.c, merging it almost completely with handling of Alias, and
10049 adding a 'notes' field to the request_rec which allows the CGI module
10050 to discover whether the Alias module has put this request through
10051 ScriptAlias (which it needs to know for back-compatibility, as the old
10052 NCSA code did not check Options ExecCGI in ScriptAlias directories).
10055 Changes with Apache 0.8.10 18 Aug 1995
10057 *) AllowOverride applies to the named directory, and not just
10058 subdirectories. [David Robinson]
10060 *) Do locking for accept() exclusion (on systems that need it)
10061 using a special file created for the purpose in /usr/tmp, and
10062 not the error log; using the error log causes real problems
10063 if it's NFS-mounted; this is known to be the cause of a whole
10064 lot of "server hang" problems with Solaris. [David Robinson;
10065 thanks to Merten Schumann for help diagnosing the problem].
10067 Changes with Apache 0.8.9 12 Aug 1995
10069 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
10071 *) Nested includes see environment variables of the including document,
10072 for NCSA bug-compatibility (some sites have standard footer includes
10073 which try to print out the last-modified date). [Eric Hagberg/Robert
10076 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
10077 URI as a CGI script, even if it would have been treated as something
10078 else if requested directly, for NCSA back-compatibility. (Note that
10079 this means that people who know the name of the script can see the
10080 code just by asking for it). [Robert Thau]
10082 *) New version of dbmmanage script included in support directory as
10085 *) Check if scoreboard file couldn't be opened, and say so, rather
10086 then going insane [David Robinson]
10088 *) POST to CGI works on A/UX [Jim Jagielski]
10090 *) AddIcon and AddAlt commands work properly [Rob Hartill]
10092 *) NCSA server push works properly --- the Arena bug compatibility
10093 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
10094 if you still want the workaround). [Rob Hartill]
10096 *) If client didn't submit any Accept-encodings, ignore encodings in
10097 content negotiation. (NB this will all have to be reworked anyway
10098 for the new HTTP draft). [Florent Guillaume]
10100 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
10102 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
10104 *) Give Redirect priority over Alias, for NCSA bug compatibility
10107 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
10108 paralleling earlier bug fix for CGI [David Robinson]
10110 *) If DBM auth is improperly configured, report a server error and don't
10113 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
10114 it seems to work well enough without it (even in a 10 hits/sec
10115 workout), and the overhead for the locking under A/UX is
10116 alarmingly high (though it is very low on other systems).
10117 [Eric Hagberg, Jim Jagielski]
10119 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
10121 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
10122 Behlendorf/Eric Hagberg]
10124 *) More improvements to default Configuration for A/UX [Jim Jagielski]
10126 *) Compiles clean on NEXT [Rob Hartill]
10128 *) Compiles clean on SGI [Robert Thau]
10130 Changes with Apache 0.8.8 08 Aug 1995
10132 *) SunOS library prototypes now never included unless explicitly
10133 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
10134 people using GNU libc on SunOS are screwed by prototypes for the
10137 (Those who wish to compile clean with gcc -Wall on a standard
10138 SunOS setup need the prototypes, and may obtain them using
10139 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
10140 with nonstandard libraries are presumably competent to make their
10143 *) Strips trailing '/' characters off both args to the Alias command,
10144 to make 'Alias /foo/ /bar/' work.
10146 Changes with Apache 0.8.7 03 Aug 1995
10148 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
10149 [reported by David Robinson]
10151 *) Compiles clean on OSF/1 [David Robinson]
10153 *) Added some of the more recent significant changes (AddLanguage stuff,
10154 experimental LogFormat support) to CHANGES file in distribution root
10157 Changes with Apache 0.8.6 02 Aug 1995
10159 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10160 (If you actually wanted a conditional GET which bypassed the cache, you
10161 couldn't get it). [Reported by Roy Fielding]
10163 *) Properly terminate headers on '304 Not Modified' replies to conditional
10164 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10165 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10167 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10169 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10170 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10171 and older versions don't set the __SUNPRO_C preprocessor variable). On
10172 all other systems, these are never used anyway. [Reported by Mark Cox].
10174 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10176 Changes with Apache 0.8.5 01 Aug 1995
10178 *) Added last-minute configurable log experiment, as optional module
10180 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10181 properly. (One-line fix to http_protocol.c).
10183 *) Work around bogus behavior when reloading from Netscape.
10184 It's Netscape's bug --- for some reason they expect a request with
10185 If-modified-since: to not function as a conditional GET if it also
10186 comes with Pragma: no-cache, which is way out of line with the HTTP
10187 spec (according to Roy Fielding, the redactor).
10189 *) Added parameter to set maximum number of server processes.
10191 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10194 *) IdentityCheck bugfix [Chuck Murcko].
10196 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10198 *) More sample config file corrections; add extension to AddType for
10199 *.asis, move AddType generic description to its proper place, and
10200 fix miscellaneous typos. [ Alexei Kosut ]
10202 *) Deleted the *other* reference to the regents from the Berkeley
10203 legal disclaimer (everyplace).
10205 *) Nuked Shambhala name from src/README; had already cleaned it out
10206 of everywhere else.
10208 Changes with Apache 0.8.4
10210 *) Changes to server-pool management parms --- renamed current
10211 StartServers to MinSpareServers, created separate StartServers
10212 parameter which means what it says, and renamed MaxServers to
10213 MaxSpareServers (though the old name still works, for NCSA 1.4
10214 back-compatibility). The old names were generally regarded as
10215 too confusing. Also altered "docs" in sample config files.
10217 *) More improvements to default config files ---
10218 sample directives (commented out) for XBitHack, BindAddress,
10219 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10220 defaults, AddTypes for send-as-is and imagemap magic types, and
10221 improvements to samples for DirectoryIndex [Alexei Kosut]
10223 *) Yet more improvements to default config files --- changes to
10224 Alexei's sample AddLanguage directives, and sample LanguagePriority
10225 [ Florent Guillaume ]
10227 *) Set config file locations properly if not set in httpd.conf
10230 *) Don't escape URIs in internal redirects multiple times; don't
10231 do that when translating PATH_INFO to PATH_TRANSLATED either.
10234 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10236 Changes with Apache 0.8.3
10238 *) Edited distribution README to *briefly* summarize installation
10239 procedures, and give a pointer to the INSTALL file in the src/
10242 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10243 recent NCSA distributions.
10245 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10246 exist for the same directory, use both and don't segfault. [Reported
10249 *) Proper makefile dependencies [David Robinson]
10251 *) Note (re)starts in error log --- reported by Rob Hartill.
10253 *) Only call no2slash() after get_path_info() has been done, to
10254 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10255 reported by Andrew Wilson, though this one is probably a real bug]
10257 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10258 dump core when Referer is not supplied. [Randy Terbush]
10260 *) Lightly edited sample config files to refer people to our documentation
10261 instead of NCSA's, and to list Rob McCool as *original* author (also
10262 deleted his old, and no doubt non-functional email address). Would be
10263 nice to have examples of new features...
10265 Changes with Apache 0.8.2 19 Jul 1995
10267 *) Added AddLanuage code [Florent Guillaume]
10269 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10271 *) All sorts of problems when MultiViews finds a directory. It would
10272 be nice if mod_dir.c was robust enough to handle that, but for now,
10273 just punt. [reported by Brian Behlendorf]
10275 *) Wait for all children on restart, to make sure that the old socket
10276 is gone and we can reopen it. [reported by Randy Terbush]
10278 *) Imagemap module is enabled in default Configuration
10280 *) RefererLog and UserAgentLog modules properly default the logfile
10283 *) Mark Cox's mod_cookies added to the distribution as an optional
10284 module (commented out in the default Configuration, and noted as
10285 an experiment, along with mod_dld). [Mark Cox]
10287 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10289 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10291 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10293 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10296 Changes with Apache 0.8.1
10298 *) New imagemap module [Randy Terbush]
10300 *) Replacement referer log module with NCSA-compatible RefererIgnore
10301 [Matthew Gray again]
10303 *) Don't mung directory listings with very long filenames.
10304 [Florent Guillaume]
10306 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10308 *) New config script. See INSTALL for info. [Robert Thau]
10310 *) Scoreboard mechanism for regulating the number of extant server
10311 processes. MaxServers and StartServers defaults are the same as
10312 for NCSA, but the meanings are slightly different. (Actually,
10313 I should probably lower the MaxServers default to 10).
10315 Before asking for a new connection, each server process checks
10316 the number of other servers which are also waiting for a
10317 connection. If there are more than MaxServers, it quietly dies
10318 off. Conversely, every second, the root, or caretaker, process
10319 looks to see how many servers are waiting for a new connection;
10320 if there are fewer than StartServers, it starts a new one. This
10321 does not depend on the number of server processes already extant.
10322 The accounting is arranged through a "scoreboard" file, named
10323 /tmp/htstatus.*, on which each process has an independent file
10324 descriptor (they need to seek without interference).
10326 The end effect is that MaxServers is the maximum number of
10327 servers on an *inactive* server machine, but more will be forked
10328 off to handle unusually heavy loads (or unusually slow clients);
10329 these will die off when they are no longer needed --- without
10330 reverting to the overhead of full forking operation. There is a
10331 hard maximum of 150 server processes compiled in, largely to
10332 avoid forking out of control and dragging the machine down.
10333 (This is arguably too high).
10335 In my server endurance tests, this mechanism did not appear to
10336 impose any significant overhead, even after I forced it to put the
10337 scoreboard file on a normal filesystem (which might have more
10338 overhead than tmpfs). [Robert Thau]
10340 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10343 *) Read .htaccess files even in directory with <Directory> section.
10344 (Former incompatibility noted on mailing list, now fixed). [Robert
10347 *) "HEAD /" gives the client a "Bad Request" error message, rather
10348 than trying to send no body *and* no headers. [Cliff Skolnick].
10350 *) Don't produce double error reports for some very obscure cases
10351 mainly involving auth configuration (the "all modules decline to
10352 handle" case which is a sure sign of a server bug in most cases,
10353 but also happens when authentication is badly misconfigured).
10356 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10357 it's *for*, and this sort of thing really shouldn't be cluttering
10358 up the Makefile). [Robert Thau]
10360 *) Incidental code cleanups in http_main.c --- stop dragging
10361 sa_client around; just declare it where used. [Robert Thau]
10363 *) Another acc-related fix. (It doesn't like const char
10364 in some places...). [Mark Cox]
10366 Changes with Shambhala 0.6.1 13 Jul 1995
10368 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10369 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10371 *) Compiles clean with acc on SunOS [Paul Sutton]
10373 *) Reordered modules in modules.c so that Redirect takes priority
10374 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10375 believe it or not, he has an actual site with a ScriptAlias and
10376 a Redirect declared for the *exact same directory*. Even *my*
10377 compatibility fetish wouldn't motivate me to fix this if the fix
10378 required any effort, but it doesn't, so what the hey.
10380 *) Fixed to properly default several server_rec fields for virtual
10381 servers from the corresponding fields in the main server_rec.
10382 [Cliff Skolnick --- 'port' was a particular irritant].
10384 *) No longer kills off nph- child processes before they are
10385 finished sending output. [Matthew Gray]
10387 Changes with Shambhala 0.6.0 10 Jul 1995
10389 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10390 the connection to the client in an "aborted" state, but otherwise
10391 allow whatever handlers are running to clean up. hard_timeout()s
10392 abort the request in progress completely; anything not tied to some
10393 resource pool cleanup will leak. They're still around because I
10394 haven't yet come up with a more elegant way of handling
10395 timeouts when talking to something that isn't the client. The
10396 default_handler and the dir_handler now use soft timeouts, largely
10397 so I can test the feature. [Robert Thau]
10399 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10400 the case of log handlers dying prematurely is probably handled VERY
10401 gracelessly at this point, and if the logger stops reading input,
10402 the server will hang. (It is known to correctly restart the
10403 logging process on server restart; this is (should be!) going through
10404 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10405 script). [Robert Thau]
10407 *) asis files supported (new module). [Robert Thau]
10409 *) IdentityCheck code is compiled in, but has not been tested. (I
10410 don't know anyone who runs identd). [Robert Thau]
10412 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10413 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10415 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10417 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10418 as timeouts are not in scope. [Robert Thau]
10420 *) quoted-string args in config files now handled correctly (doesn't drop
10421 the last character). [Robert Thau; reported by Randy Terbush]
10423 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10424 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10426 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10427 default default type); the former default default behavior when all
10428 type-checkers defaulted had been a core dump. [Paul Sutton]
10430 *) Copy filenames out of the struct dirent when indexing
10431 directories. (On Linux, readdir() returns a pointer to the same
10432 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10434 Changes with Shambhala 0.5.3 [not released]
10436 *) Default response handler notes "file not found" in the error log,
10437 if the file was not found. [Cliff Skolnick].
10439 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10440 code no longer sets up bogus PATH_INFO which fakes out the directory
10441 handler). [Cliff Skolnick]
10443 Changes with Shambhala 0.5.2 06 Jul 1995
10445 *) Changes to http_main.c --- root server no longer plays silly
10446 games with SIGCHLD, and so now detects and replaces dying
10447 children. Child processes just die on SIGTERM, without taking
10448 the whole process group with them. Potential problem --- if any
10449 child process refuses to die, we hang in restart.
10450 MaxRequestsPerChild may still not work, but it certainly works
10451 better than it did before this! [Robert Thau]
10453 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10454 work (or work better, at least); over-long description lines
10455 properly terminated. [Mark Cox]
10457 *) http_request.c now calls unescape_url() more places where it
10458 should [Paul Sutton].
10460 *) More directory handling bugs (reported by Cox)
10461 Parent Directory link is now set correctly. [Robert Thau]
10463 Changes with Shambhala 0.5.1 04 Jul 1995
10465 *) Generalized cleanup interface in alloc.c --- any function can be
10466 registered with alloc.c as a cleanup for a resource pool;
10467 tracking of files and file descriptors has been reimplemented in
10468 terms of this interface, so I can give it some sort of a test.
10471 *) More changes in alloc.c --- new cleanup_for_exec() function,
10472 which tracks down and closes all file descriptors which have been
10473 registered with the alloc.c machinery before the server exec()s a
10474 child process for CGI or <!--#exec-->. CGI children now get
10475 started with exactly three file descriptors open. Hopefully,
10476 this cures the problem Rob H. was having with overly persistent
10477 CGI connections. [Robert Thau]
10479 *) Mutual exclusion around the accept() in child_main() --- this is
10480 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10481 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10482 This uses fcntl(F_SETLK,...) on the error log descriptor because
10483 flock() on that descriptor won't work on systems which have BSD
10484 flock() semantics, including (I think) Linux 1.3 and Solaris.
10486 This does work on SunOS (when the server is idle, only one
10487 process in the pool is waiting on accept()); it *ought* to work
10488 on the other systems. [Robert Thau]
10490 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10492 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10494 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10496 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10497 be unnecessary if I go to the revised timeout-handling scheme).
10500 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10501 string) even if none came in with the request. [Robert Thau]
10503 *) CHANGES file added to distribution ;-).
10505 Changes with Shambhala 0.4.5
10507 *) mod_dld --- early dynamic loading support [rst]
10508 *) Add wildcard content handlers for XBITHACK; default_hander now
10509 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10510 *) XBITHACK supported as a wildcard content-handler, and
10511 configurable at run-time (not just at compile time, as in the
10512 "patchy server" releases) [rst]
10514 Changes with Shambhala 0.4.4 30 Jun 1995
10516 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10517 *) Handle Addtype x/y .z [rst, reported by Cox]
10519 Changes with Shambhala 0.4.3
10521 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10522 synonymous [rst, terbush]
10524 Changes with Shambhala 0.4.1 28 Jun 1995
10526 *) First-cut virtual host implementation; some refit in the config
10527 reading code, and log management, was necessary to support this [rst]
10528 *) Sub-pool machinery, originally added to avoid excessive storage
10529 allocation on listings of large directories (which turned out to
10530 be the problem that the 0.3 storage accounting was added to
10531 find). Subrequests and mod_dir changed to use subpools. [rst]
10532 *) More memory debugging --- free list consistency checks. [rst]
10533 *) Added err_headers to request_rec, with support elsewhere [rst]
10534 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10536 Changes with Shambhala 0.3 19 Jun 1995
10538 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10539 *) Don't compile in mod_ai_backcompat by default
10540 *) Switch name of server from Apache to Shambhala in Makefile
10541 *) Add some accounting routines to track memory usage in the pools,
10544 Changes with Shambhala 0.2
10546 *) Set DOCUMENT_ROOT CGI variable
10547 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10548 *) Add critical section protection to handling of cleanup structures
10550 *) Significant code reorg within the server core to group related
10551 functions together [rst]
10552 *) Correctly handle clients that hang up before sending any request
10554 *) Replace dying child processes. [rst]
10556 Changes with Shambhala 0.1 12 Jun 1995
10558 Major rewrite of the pre-existing "patchy server" codebase, by
10559 Robert Thau (rst). Significant portions of the server code, such
10560 as configuration-file handling and HTTP authentication support,
10561 were ripped out and rewritten from scratch. Code that was not
10562 completely rewritten was significantly altered.
10564 Major changes with this release include:
10566 *) Introduction of the module API; in request handling, the central
10567 machinery just dispatches to various modules, which actually do
10568 most of the work. Configuration handling is similar --- modules
10569 declare their own commands, and the central machinery just
10570 dispatches to them.
10572 API features from shambhala/0.1 were substantially unchanged in
10573 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10574 release, such as wildcard handlers and subpools, were added in
10575 subsequent Shambhala releases, and were also generally rst's
10578 *) This release included the following modules:
10580 mod_access (access control --- allow and deny directives),
10581 mod_alias (Alias and Redirect commands),
10582 mod_auth (straight HTTP authentication, based on flat-files)
10583 mod_auth_dbm (same, with dbm files)
10584 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10585 mod_common_log (CLF access logs; later renamed mod_log_common)
10586 mod_dir (directory indexing)
10587 mod_include (server-side includes)
10588 mod_mime (AddType directives)
10589 mod_negotiation (content negotiation)
10590 mod_userdir (support for users' public_html directories)
10592 It also included a mod_ai_backcompat, which was a private hack
10593 for back-compatibility with rst's own AI-lab servers.
10595 All of these modules were substantially complete, and functional
10596 or nearly so (a few, which implemented features not in use at
10597 Thau's site, required patches of a few lines).
10599 *) sub-request machinery, to allow modules to determine how other
10600 modules would assign MIME types to a given file, or optionally
10601 serve its content (this is heavily used by mod_dir, mod_include
10602 and mod_negotiation).
10604 *) Resource pool system for keeping track of memory allocated and
10605 files opened in service of a particular request. Much of the
10606 code in the modules (when they weren't rewrites) was adjusted to
10607 replace a pervasive convention of using fixed-size buffers on
10608 the stack with an equally pervasive convention of using memory
10609 allocated with palloc().
10611 *) Reorganization of data structures associated with a given
10612 request to eliminate use of global variables and the troublesome
10613 unmunge_name function (used in NCSA and early Apache releases to
10614 attempt to determine the URI which mapped to a given filename
10615 --- a difficult proposition, given that it is easy to produce
10616 setups in which multiple URIs map to the same file).
10618 *) Source files renamed and rearranged
10620 *) Very simple pre-forking behavior --- parent process forked off a
10621 fixed number of children, and then just waited for SIGHUP.
10623 *) Other more minor changes too numerous to list.
10625 This release included modified versions of a lot of code from the
10626 Apache 0.6.4 public release, plus an early pre-forking patch
10627 codeveloped by Robert Thau and Rob Hartill.
10629 Changes with Apache 0.7.3 20 Jun 1995
10631 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10632 were incorporated by Rob Hartill on the main branch while Robert Thau
10633 worked on the Shambhala rewrite above. Most were merged into the
10634 Shambala architecture after Apache 0.8.0.
10636 Changes with Apache 0.6.4 13 May 1995
10638 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10641 Changes with Apache 0.5.1 10 Apr 1995
10643 Changes with Apache 0.4 02 Apr 1995
10645 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10648 Changes with Apache 0.3 24 Mar 1995
10650 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10653 Changes with Apache 0.2 18 Mar 1995
10655 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10656 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10657 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
