1 Changes with Apache 2.0.30-dev
3 *) Change make install processing of DSO modules to perform special
4 handling on platforms where libtool doesn't install mod_foo.so.
5 This fixes some wonkiness on HP-UX, Tru64, and AIX which
6 prevented standard LoadModule statements from working.
9 *) Whenever mod_so is enabled (not just when there are DSOs for
10 our modules), do whatever special magic is required for compiling/
11 loading third-party modules. This allows third-party DSOs to
12 be used on an AIX build when there were no built-in modules
13 built as DSOs. (This should help on OS/390 and BeOS as well.)
16 *) Allow apxs to be used to build DSOs on AIX without requiring the
17 user to hard-code the list of import files. (This should help
18 on OS/390 and BeOS as well.) [Jeff Trawick]
20 *) Resolved segfault in mod_isapi when configuring with ISAPICacheFile.
21 PR 8563, 8919 [William Rowe]
23 *) Get binary builds working when libapr and libaprutil are built
26 *) Get shared builds of libapr and libaprutil, as well as Apache DSOs,
27 working on AIX. [Aaron Bannert, Dick Dunbar <RLDunbar@pacbell.net>,
28 Gary Hook <ghook@us.ibm.com>, Victor Orlikowski, Jeff Trawick]
30 *) Fix the handling of SSI directives in which the ">" of the
31 terminating "-->" is the last byte in a file [Brian Pane]
33 *) Add back in the "suEXEC mechanism enabled (wrapper: /path/to/suexec)"
34 message that we had back in apache-1.3 and still have scattered
35 throughout our docs. [Aaron Bannert]
37 *) Prevent the Win32 port from continuing after encountering an
38 error in the command line args to apache. [William Rowe]
40 *) On a error in the proxy, make it write a line to the error log
43 Changes with Apache 2.0.29
45 *) Add buffering in core_output_filter to ensure that long
46 lists of small buckets don't cause small packet writes.
47 [Brian Pane, Ryan Bloom]
49 *) Fix the installation target to make sure that the manual is
50 installed in the correct location.
51 [Yoshifumi Hiramatsu <hiramatu@boreas.dti.ne.jp> and
52 Gomez Henri <hgomez@slib.fr>]
54 *) Fix the cmd command for mod_include. When we are processing
55 a cmd command, we do not want to use the r->filename to set
56 the command name. The command comes from the SSI tag. To do this,
57 I added a variable to the function that builds the command line
58 in mod_cgi. This allows the include_cmd function to specify
59 the command line itself. [Ryan Bloom]
61 *) Change open_logs hook to return a value, allowing you
62 to flag a error while opening logs
63 [Ian Holsman, Doug MacEachern]
65 *) Change post_config hook to return a value, allowing you
66 to flag a error post config
67 [Ian Holsman, Jeff Trawick]
69 *) Allow SUEXEC_BIN (the path to the suexec binary that is
70 hard-coded into the server) to be specified to the configure
71 script by the --with-suexec-bin parameter. [Aaron Bannert]
73 *) Fix segv in worker MPM following accept on pipe-of-death
76 *) Add mod_deflate to experimental.
77 [Ian Holsman, Justin Erenkrantz]
79 *) Bail out at configure time if an invalid MPM was specified.
80 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
82 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
83 configured [John Sterling <sterling@covalent.net>]
85 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
87 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
89 *) Optimization for the BNDM string-search function in
90 mod_include. [Brian Pane]
92 *) Fixed the behavior of the XBitHack directive.
93 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
95 *) The threaded MPM for Unix has been removed. Use the worker
96 MPM instead. [various]
98 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
99 in logging the error from a failed DNS lookup. [Jeff Trawick]
101 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
104 *) Get mod_cgid killed when a MPM exits due to a fatal error.
107 *) Fix a file descriptor leak in mod_include. When we include a
108 file, we use a sub-request, but we didn't destroy the sub-request
109 immediately, instead we waited until the original request was
110 done. This patch closes the sub-request as soon as the data is
111 done being generated. [Brian Pane <bpane@pacbell.net>]
113 *) Allow modules that add sockets to the ap_listeners list to
114 define the function that should be used to accept on that
115 socket. Each MPM can define their own function to use for
116 the accept function with the MPM_ACCEPT_FUNC macro. This
117 also abstracts out all of the Unix accept error handling
118 logic, which has become out of synch across Unix MPMs.
121 *) Fix a bug which would cause the response headers to be omitted
122 when sending a negotiated ErrorDocument because the required
123 filters were attached to the wrong request_rec.
124 [John Sterling <sterling@covalent.net>]
126 *) Remove commas from the end of the macros that define
127 directives that are used by MPMs. Prior to this patch,
128 you would use these macros without commas, which was unlike
129 the macros for any other directives. Now, the caller provides
130 the comma rather than the macro providing it. This makes
131 the macros look more like the rest of the directives.
132 [Ryan Bloom and Cliff Woolley]
134 *) Add 'redirect-carefully' environment option to disable sending
135 redirects under special circumstances. This is helpful for
136 Microsoft's WebFolders when accessing a directory resource via
137 DAV methods. [Justin Erenkrantz]
139 *) Begin to abstract out the underlying transport layer.
140 The first step is to remove the socket from the conn_rec,
141 the server now lives in a context that is passed to the
142 core's input and output filters. This forces us to be very
143 careful when adding calls that use the socket directly,
144 because the socket isn't available in most locations.
147 *) Really reset the MaxClients value in worker and threaded
148 when the configured value is not a multiple of the number
149 of threads per child. We said we did previously but we
150 forgot to. [Jeff Trawick]
152 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
154 *) If shared modules are requested and mod_so is not available,
155 produce a fatal config-time error. [Justin Erenkrantz]
157 *) Improve http2env's performance by cutting the work it has to
158 do. [Brian Pane <bpane@pacbell.net>]
160 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
161 [Brian Pane <bpane@pacbell.net>]
163 Changes with Apache 2.0.28
165 *) Fix infinite loop in mod_cgid.c.
166 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
168 *) When no port is given in a "ServerName host" directive, the
169 server_rec->port is now set to zero, not 80. That allows for
170 run-time deduction of the correct server port (depending on
171 SSL/plain, and depending also on the current setting of
172 UseCanonicalName). This change makes redirections
173 work, even with https:// connections. As in Apache-1.3, the
174 connection's actual port number is never used, only the ServerName
175 setting or the client's Host: setting. Documentation updated
176 to reflect the change. [Martin Kraemer]
178 *) Add a '%{note-name}e' argument to mod-headers, which works in
179 the same way as mod_log_confg. [Ian Holsman]
181 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
182 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
183 MPMs. [Cliff Woolley]
185 *) Introduce htdbm, a user management utility for db/dbm authorization
186 databases. [Mladen Turk <mturk@mappingsoft.com>]
188 *) Optimize usage of strlen and strcat in ap_directory_walk.
189 [Brian Pane <bpane@pacbell.net>]
191 Changes with Apache 2.0.27
193 *) Introduce an Apache mod_ssl initial configuration template
194 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
196 *) Fixed a memory leak in the getline parsing code that could
197 be triggered by arbitrarily large header lines. Requests
198 from the core input filter for single lines are now limited
199 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
201 *) Fix a truncation bug in how we print the port on the Via: header.
202 The routine that prints the Via: header now takes a length for
203 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
205 *) Some syntax errors in mod_mime_magic's magic file can result
206 in a 500 error, which previously was unlogged. Now we log the
207 error. [Jeff Trawick]
209 *) Add the support/checkgid helper app, which checks the run-time
210 validity of group identifiers usable in the Group directive.
213 *) Various --enable-so options have been fixed: --enable-so is
214 treated as "static"; explicit --enable-so=shared issues an error;
215 and explicit --enable-so fails with error on systems without
216 APR_HAS_DSO. [Aaron Bannert]
218 *) Fix a segfault in the core input filter when the client socket
219 gets disconnected unexpectedly. [Cliff Woolley]
221 *) Fix the reporting for child processes that die. This removes
222 all of the non-portable W* macros from Apache.
223 [Jeff Trawick and Ryan Bloom]
225 *) Win32: Track and display "Parent Server Generation:" in
226 mod_status output. The generation will be bumped at
227 server graceful restart, when the child process exits
228 by hitting MaxRequestsPerChild or if the child
229 process exits abnormally. [Bill Stoddard]
231 *) Win32: Fix problem where MaxRequestsPerChild directive was
232 not being picked up in favor of the default. Enable
233 the parent to start up a new child process immediately upon
234 the old child starting shutdown.
237 *) Fix some bungling of the remote port in rfc1413.c so that
238 IdentityCheck retrieves the proper user id instead of failing
239 and thus always returning "nobody."
240 [Dick Streefland <Dick.Streefland@xs4all.nl>]
242 *) Introduced thread saftey for mod_rewrite's internal cache.
243 [Brian Pane <bpane@pacbell.net>]
245 *) Simplified mod_env's directives to behave as most directives are
246 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
247 directive following that UnsetEnv within the same container.
248 Also provides a runtime startup warning if a PassEnv configured
249 environment value is undefined. [William Rowe]
251 *) The worker MPM is now completely ported to APR's new lock API. It
252 uses native APR types for thread mutexes, cross-process mutexes,
253 and condition variables. [Aaron Bannert]
255 *) Sync up documentation to remove all references to the now deprecated
256 Port directive. [Justin Erenkrantz]
258 *) Moved all ldap modules from the core to httpd-ldap sub-project
261 *) Exit when we can't listen on any of the configured ports. This
262 is the same behavior as 1.3, and it avoids having the MPMs to
263 deal with bogus ap_listen_rec structures. [Jeff Trawick]
265 *) Cleanup the proxy code that creates a request to the origin
266 server. This change adds an optional hook, which allows modules
267 to gain control while the request is created if the proxy module
268 is loaded. The purpose of this hook is to allow modules to add
269 input and/or output filters to the request to the origin. While
270 I was at it, I made the core use this hook, so that proxy request
271 creation uses some of the code from the core. This can still be
272 greatly improved, but this is a good start. [Ryan Bloom]
274 Changes with Apache 2.0.26
276 *) Port the MaxClients changes from the worker MPM to the threaded
279 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
280 with the new input filtering system. [Justin Erenkrantz]
282 *) Introduce the MultiviewsMatch directive, to allow the operator
283 to be flexible in recognizing Handlers and Filters filename
284 extensions as part of the Multiviews matching logic, strict with
285 MultiviewsMatch NegotiatedOnly to accept only filename extentions
286 that designate negotiated parameters, (content type, charset, etc.)
287 or MultiviewsAll for the 1.3 behavior of matching any files, even
288 if they have unregistered extensions. [William Rowe]
290 *) Fixed the configure script to add a LoadModule directive to
291 the default httpd.conf for any module that was compiled
292 as a DSO. [Aaron Bannert <aaron@clove.org>]
294 *) rewrite mod_ssl input filtering to work with the new input filtering
295 system. [Justin Erenkrantz]
297 *) prefork: Don't segfault when we are able to listen on some but
298 not all of the configured ports. [Jeff Trawick]
300 *) Build mod_so even if no core modules are built shared.
301 [Aaron Bannert <aaron@clove.org>]
303 *) Introduce ap_directory_walk rewrite (with further optimizations
304 required) to adapt to the ap_process_request_internal() changes.
305 Optimized so subrequests and redirects now reuse previous section
306 merges, until we mismatch with the original directory_walk, and
307 precomputed r->finfo results will cause directory_walk to skip
308 the most expensive phases of the function. [William Rowe]
310 *) Allow ApacheMonitor to connect to and control Apache on other
311 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
313 *) Remove the Port directive. In it's place, the Listen directive
314 is now a required directive, which tells Apache what port to
315 listen on. The ServerName directive has also been extended
316 to accept an optional port. If the port is specified to the
317 ServerName, the server will report that port whenever it
318 reports the port that it is listening on. This change was
319 made to ease configuration errors that stem from having a Port
320 directive, and a Listen directive. In that situation, the server
321 would only listen to the port specified by the Listen command,
322 which caused a lot of confusion to users. [Ryan Bloom]
324 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
325 build, as loadable modules. [William Rowe]
327 *) Fix --enable-mods-shared processing. If most is specified,
328 then all modules that can be compiled as shared modules are.
329 [Aaron Bannert <aaron@clove.org>]
331 *) Update the mime.types file to map video/vnd.mpegurl to mxu
332 and add commonly used audio/x-mpegurl for m3u extensions.
333 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
335 *) Eliminate the depreciated r->content_language, in favor of the array
336 r->content_languages introduced many years ago. Module authors must
337 substantially overhaul their modules, so this needs to be upgraded
338 if the module still relied on backwards-brokeness. [William Rowe]
340 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
343 *) Rewrite the input filtering mechanisms to consolidate and reorganize
344 code. In short, core_input_filter does something now and
345 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
347 *) Update the Win32 build to re-absorb mod_proxy and family.
350 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
351 current SDK.) [William Rowe]
353 *) Some style changes to the code that does ProxyErrorOverride. Fixed
354 config merge behaviour. [Graham Leggett]
356 *) Allow support programs to be compiled against a static version
357 of libapr. This allows the smaller support programs to be
358 relocated. [Aaron Bannert <aaron@clove.org>]
360 *) Update the mime.types file to the registered media types as
361 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
363 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
364 number of clients that can connect at the same time, instead of
365 specifying the maximum number of child processes.
366 [Aaron Bannert <aaron@clove.org>]
368 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
369 be consistent with 1.3. [Justin Erenkrantz]
371 *) Cache apr_explode_localtime() value for 15 seconds.
372 [Brian Pane <bpane@pacbell.net>]
374 *) Fix mod_include to not return ETag or Last-Modified headers.
375 [Ian Holsman <ianh@cnet.com>]
377 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
379 *) Eliminate the wasteful run-time conversion of method names from strings
380 to numbers in places where the methods are known at compile time.
381 [Brian Pane <bpane@pacbell.net>]
383 *) Turn the worker MPM's queue into a LIFO. This may
384 improve cache-hit performance under some conditions.
385 [Aaron Bannert <aaron@clove.org>]
387 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
388 support it. [Justin Erenkrantz]
390 *) Cleanup the worker MPM. We no longer re-use transaction
391 pools. This incurs less overhead than shuffling the pools
392 around so that they can be re-used. Remove one of the
393 queue's condition variables. We just redefined the API to
394 state that you can't try to add more stuff than you allocated
395 segments for. [Aaron Bannert <aaron@clove.org>]
397 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
399 *) Fixed persistent connections when a request contains a body.
402 *) mod_dav uses a new API to speak to the backend provider for dead
403 property management. [Greg Stein]
405 *) Remove the Win32 script-processing exception from mod_cgi, and
406 roll build_command_line/build_argv_list into a unified, overrideable
407 ap_cgi_build_command optional function. [William Rowe]
409 *) Rewrite find_start_sequence to use a better search algorithm
410 to find the start tag. [Justin Erenkrantz]
412 *) Fix a seg fault in mod_include. When we are generating an
413 internal redirect, we must set r->uri to "", not a bogus
414 string, and not NULL. [Ryan Bloom]
416 *) Optimized location_walk, so subrequests, redirects and second passes
417 now reuse previous section merges on a <Location > by <Location >
418 basis, until we mismatch with the original location_walk.
421 *) Back out the 1.45 change to util_script.c. This change made
422 us set the environment variable REQUEST_URI to the redirected
423 URI, instead of the originally requested URI.
424 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
426 *) Make mod_include do lazy evaluation of potentially expensive to
427 compute variables. [Brian Pane <bpane@pacbell.net>]
429 *) Fix logging of bytes sent for HEAD requests. %b and %B should
430 log either - or 0, before this patch, they were both logging
431 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
433 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
434 than per character. [Brian Pane <bpane@pacbell.net>]
436 *) Normalize the primary request, redirects and sub-requests to
437 run the same ap_process_request_internal for consistency in
438 robustness, behavior and security. [William Rowe]
440 *) Fix a segfault with mod_include when r->path_info is not set
441 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
443 *) Add -X functionality back. This indicates to all MPMs and any other
444 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
446 *) Some initial support for the cygwin platform [prefork only].
447 This is not to be confused with support for the WinNT/Win32
448 platform, which is the recommended configuration for native
449 Win32 users. The cygwin platform support is recommended for
450 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
452 *) Changed syntax of Set{Input|Output}Filter. The list of filters
453 must be semicolon delimited (if more than one filter is given.)
454 The Set{Input|Output}Filter directive now overrides a parent
455 container's directive (e.g. SetInputFilter in <Directory /web/foo>
456 will override any SetInputFilter directive in <Directory /web>.)
457 This new syntax is more consistent with Add{Input|Output}Filter
458 directives defined in mod_mime. Also cures a bug in prior releases
459 where the Set{Input|Output}Filter directive would corrupt the
460 global configuration if the multiple directives were nested.
463 *) Cured what's ailed mime for quite some time. If an AddSomething
464 was given in the configuration (Language, Charset, Handler or
465 Encoding) Apache would set the content type as given by AddType,
466 but refused to check the mime.types file if AddType wasn't given
467 for that specific extension. Setting the AddHandler for .html
468 without setting the AddType text/html html would cause Apache to
469 use the default content type. [William Rowe]
471 *) Added some bulletproofing to memory allocation in the LDAP cache
472 code. [Graham Leggett]
474 Changes with Apache 2.0.25
476 *) Move the installed /manual directory out of the /htdocs/ tree, so
477 that it can be kept more independently from the remaining document
478 root. The "Alias /manual ..." already allowed for easy projection
479 into existing private document trees. [Martin Kraemer]
481 *) Add specified user attributes to the environment when using
482 mod_auth_ldap. This allows you to use mod_include to embed specified
483 user attributes in a page like so:
484 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
487 *) Fix a performance problem with the worker MPM. We now create
488 transaction pools once, and re-use them for each connection.
489 [Aaron Bannert <aaron@clove.org>]
491 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
492 of a 'handler' or 'filter', so that any filename extension that does
493 not contribute to the negotiated metadata can't be served without
494 an explicit request. E.g., if the .Z extension is associated with
495 an unzip filter, the user request somefile.Z.html, mod_negotiation
496 won't serve it. It can serve somefile.Z.html when somefile.Z is
497 requested, since the .Z extension is explictly requested, if the
498 .html extension is associated with ContentType text/html.
501 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
502 and corresponding AddOutputFilter syntax, to insert one or more
503 filters by mod_mime filename extension processing.
506 *) Fix a growing connection pool in core_output_filter() for
507 keepalive requests. [Jeff Trawick]
509 *) Moved split_and_pass_pretag_buckets back to being a
510 macro at Ryans's request. Removed the return from it
511 by setting and returning a return code instead. Updated
512 the code to check the return code from the macro and
513 do the right thing. [Paul J. Reder]
515 *) Fix a segfault when a numeric value was received for Host:.
518 *) Add a function ap_remove_input_filter. This is to match
519 up with ap_remove_output_filter. [Ryan Bloom]
521 *) Clean up location_walk, so that this step performs a minimum
522 amount of redundant effort (it must be run twice, but it will no
523 longer reparse all <Location > blocks when the request uri
524 hadn't changed.) [William Rowe]
526 *) Eliminate proxy: (and all other 'special') processing from the
527 ap_directory_walk() phase. Modules that want to use special
528 walk logic should refer to the mod_proxy map_to_location example,
529 with it's proxy_walk and proxysection implementation. This makes
530 either directory_walk flavor much more legible, since that phase
531 only runs against real <Directory > blocks.
534 *) Fix a security problem in mod_include which would allow
535 an SSI document to be passed to the client unparsed.
536 [Cliff Woolley, Brian Pane]
538 *) Introduce the map_to_storage hook, which allows modules to bypass
539 the directory_walk and file_walk for non-file requests. TRACE
540 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
541 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
544 *) Add the ability for mod_include to add the INCLUDES filter
545 if the file is configured for the server-parsed handler.
546 This makes the configuration for .shtml files much easier
547 to understand, and allows mod_include to honor Apache 1.3
548 config files. Based on Doug MacEachern's patch to PHP
549 to do the same thing. [Ryan Bloom]
551 *) force OpenSSL to ignore process local-caching and to always
552 get/set/delete sessions using mod_ssl's callbacks
553 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
554 Geoff Thorpe <geoff@geoffthorpe.net>]
556 *) Make the worker MPM shutdown and restart cleanly. This also
557 cleans up some race conditions, and gets the worker using
558 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
560 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
562 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
564 *) Fix for mod_include. Ryan's patch to check error
565 codes put a return in the wrong place. Also, the
566 include handler return code wasn't being checked.
567 I don't like macros with returns, so I converted
568 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
569 [Paul J. Reder <rederpj@raleigh.ibm.com>]
571 *) fix segv in mod_mime if no AddTypes are configured
572 [John Sterling <sterling@covalent.net>]
574 *) Enable ssl client authentication at SSL_accept time
575 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
577 *) Fix a segfault in mod_include when the original request has no
578 associated filename (e.g., we're filtering the error document for
579 a bad URI). [Jeff Trawick]
581 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
583 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
584 of httpd is started and shuts down due to socket conflict. Moving the
585 call to ap_log_pid solves the problem.
587 *) Changed the late-1.3 log_config substitution %c to %X, to log the
588 status of the closed connection, as it conflicts with the far more
589 common, historical ssl logging directive %...{var}c. [William Rowe]
591 *) Added the common error/ tree to the build/install targets
592 (similar to the common icons/ tree) for the multi-language error
593 messages that Lars committed earlier. [William Rowe]
595 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
597 *) Added a default commented-out mod_ldap and mod_auth_ldap
598 configuration to httpd-std.conf and httpd-win.conf
601 *) Added documentation for mod_ldap and mod_auth_ldap.
604 *) Enabled negative caching on attribute comparisons in the LDAP cache.
605 Fixed a problem where the default cache TTL was set in milliseconds
606 not microseconds causing the cache to time out almost immediately.
609 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
610 module code to follow APR. [Graham Leggett]
612 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
613 cleaned up when the connection pool pool is cleaned up.
616 *) Fix a minor issue with Jeff Trawick's mod_include
617 patch. Without this patch, the code will just allocate
618 more bytes in get_combined_directive than are needed.
621 *) Added the LDAP authentication module mod_auth_ldap.
622 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
624 *) Added the LDAP cache and connection pooling module mod_ldap.
625 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
627 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
628 by allowing a module to disable itself if its prerequisites are not
629 met. [Justin Erenkrantz]
631 Changes with Apache 2.0.24
633 *) Fix a couple of issues in mod_include when the tag appeared at
634 offsets near 8192 in the file being parsed. [Jeff Trawick]
636 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
637 reached. [Jeff Trawick]
639 *) Numerous improvements to the Win32 build system. Introduced command line
640 builds without requiring .mak files for MSVC 6.0 and later versions.
641 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
644 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
645 reporting of uninstalled services and other error conditions, and changed the
646 default service name to Apache2. [William Rowe]
648 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
649 compatibility with existing Apache 1.3 Win32 Apache management utilites.
650 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
652 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
653 [William Rowe, Greg Ames]
655 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
656 and RemoveCharset directives. [William Rowe]
658 *) The Unix MPMs other than perchild now allow child server
659 processes to use the accept mutex when starting as root and
660 using SysV sems for the accept mutex. Previously, this
661 combination would lead to fatal errors in the child server
662 processes. perchild can't use SysV sems because of security
663 issues. [Jeff Trawick, Greg Ames]
665 *) Added Win32 revision stamp resources to all http binaries
666 (including modules/ and support/ tools.) PR7322 [William Rowe]
668 *) Fix ap_rvprintf to support more than 4K of data at one time.
669 [Cody Sherr <csherr@covalent.net>]
671 *) We have always used the obsolete/deprecated Netscape syntax
672 for our tracking cookies; now the CookieStyle directive
673 allows the Webmaster to choose the Netscape, RFC2109, or
674 RFC2965 format. The new CookieDomain directive allows the
675 setting of the cookie's Domain= attribute, too. PR #s 5006,
676 5023, 5920, 6140 [Ken Coar]
678 *) Tweak server/Makefile so that the rules for generating exports.c
679 are compatible with make utilities which don't expand wildcards
680 in a dependency list (e.g., OS/390 make, certain levels of GNU
681 make). [Jeff Trawick]
683 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
685 *) Begin to sanitize the MPM configuration directives. Now, all
686 MPMs use the same functions for all common MPM directives. This
687 should make it easier to catch all bugs in these directives once.
688 [Cody Sherr <csherr@covalent.net>]
690 *) Close a major resource leak. Every time we had issued a
691 graceful restart, we leaked a socket descriptor.
694 *) Fix a problem with the new method code. We need to cast
695 the 1 to an apr_int64_t or it will be treated as a 32-bit
696 integer, and it will wrap after being shifted 32 times.
697 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
699 *) Fix a bug in mod_expires. Previous to this patch, if you
700 told mod_expires to add 604800 seconds to the last-modified
701 time, it actually added 604800 usec's to the last-modified time,
702 so that when looking at the response it looked like nothing
703 had been done. The root of the problem was that we always compute
704 time in usec's, but we ask users to input sec's. This means we
705 need to convert to usec's before using those values.
708 *) The worker MPM now handles shutdown and restart requests. It
709 definitely isn't perfect, but we do stop the servers correctly.
710 The biggest problem right now is that SIGHUP causes the server to
711 just die. [Ryan Bloom]
713 Changes with Apache 2.0.23
715 *) Use the prefork MPM by default on Unix. [various]
717 *) Added a systray icon monitor application for Win32.
718 [Mladen Turk <mturk@mappingsoft.com>]
720 *) mod_rewrite: Fix the line ending on some non-Unix systems for
721 messages written to the rewrite log.
722 [Richard Labennett <rlabenn@us.ibm.com>]
724 *) All mod_autoindex query parsing is now quietly quashed with the
725 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
726 still drops the column sort <a href>'s for the column headers, but
727 IgnoreClient is required to ignore these Query options entirely.
730 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
731 to allow the client to select plain, FancyIndexing or HTMLTable
732 formatting, V=[0|1] to inhibit or enable version sorting, and
733 P=pattern to return only specific files. The old Query Arguments
734 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
735 as before), and O=A|D for ordering ascending or descending.
738 *) Fixed an error in mod_include's directive parsing routines which
739 caused #if, #elif, and #else expressions containing backslashes
740 to be improperly evaluated. [Cliff Woolley]
742 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
743 drop the icon column, SuppressRules to drop the <hr> elements,
744 and HTMLTable to create rudimentary HTML table listings (implies
745 FancyIndexing). [William Rowe]
747 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
748 from Apache 1.3.15. This is needed for two reasons, first, given
749 multiple machines within a server farm, ETags and Last-Modified
750 stamps won't correspond from machine to machine, and second, many
751 Unixes don't capture changes to the date or time stamp of existing
752 files, since these don't modify the dirent itself. [William Rowe]
754 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
755 and DirectoryWidth options from Apache 1.3.10.
756 [William Rowe, Ken Coar]
758 *) Eliminated FancyIndexing directive, deprecated early in Apache
759 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
761 *) mod_autoindex now excludes any file names that would result in
762 an error, other than a success or redirect. Also optimized
763 the parent directory, always included except in the URI '/'.
766 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
767 negotiated index pages, and prevent the server from defaulting
768 to an autoindex of the directory. mod_negotiation will now die
769 with a 500 Internal Error if it could match some filenames
770 (e.g. for mod_dir) but none can be served. mod_negotation now
771 refuses to serve any file with an extention that mod_mime doesn't
772 recognize, and wasn't part of the request. [William Rowe]
774 *) Eliminate mod_cgi's handling of .exe files without the .exe file
775 extension. This is already handled by multiviews, if the admin
776 wishes to AddHandler .exe or define a content type handler and
777 associate .exe files with that content type. Multiviews must be
778 enabled to allow these to be served. [William Rowe]
780 *) Speed up the server's response to a spike in incoming workload
781 or restarts by assigning empty scoreboard slots to new processes
782 when they are available. [Greg Ames]
784 *) Add a handler to mod_includes.c. This handler is designed to
785 implement the XbitHack directive. This can't be done with a
786 fixup, because we need to check the content-type, which is
787 only available in the handler phase. [Ryan Bloom]
789 *) Make the includes filter check return codes from filters lower in
790 the filter chain. If a lower level filter returns an error, then
791 the request needs to stop immediately. This allows mod_include to
792 stop parsing data once a lower filter recognizes an error.
795 *) Add the ability to extend the methods that Apache understands
796 and have those methods <limit>able in the httpd.conf. It uses
797 the same bit mask/shifted offset as the original HTTP methods
798 such as M_GET or M_POST, but expands the total bits from an int to
799 an ap_int64_t to handle more bits for new request methods than
800 an int provides. [Cody Sherr <csherr@covalent.net>]
802 *) Fix broken mod_mime behavior in merging its arguments. Possible
803 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
805 *) Solve many mod_ssl porting issues (too many to detail) with
806 help from the whole team, but most notably [Ralf S. Engelschall,
807 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
808 Doug MacEachern, William Rowe, Cliff Woolley]
810 *) More stall fixes for the threaded & worker mpm's.
811 Make mod_status output more accurate. Don't
812 count workers in processes which aren't actively
813 serving requests. [Greg Ames]
815 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
817 *) Add a single listener/multiple worker MPM. This MPM is
818 definately not fully correct, but it allows us to solve many
819 of the problems that exist in the threaded MPM. This is a
820 modified version of the threaded MPM. [Ryan Bloom]
822 *) Improve content generation throughout Apache, providing closer
823 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
824 Transitional specifications. [William Rowe]
826 Changes with Apache 2.0.22
828 *) Fix a problem where the threaded MPM stalls after restarts or
829 segfaults. Also prevent multiple active processes from using
830 the same scoreboard slot. [Greg Ames]
832 *) Apache/Win32 now fills in the service description with Apache's
833 server version string, including loaded and advertised modules.
836 *) Improved support for the Win32 build, to recover gracefully from
837 missing apr or apr-util directories or the awk interpreter,
838 create the proper cgi-bin examples, including a test-cgi.bat, and
839 fix the perl shebang line for printenv.pl, when installing from
840 the build environment. [William Rowe]
842 *) Fix a segfault in threaded.c caused by passing uninitialized
843 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
845 *) Use new APR number conversion functions to reduce CPU consumption
846 when setting the content length, and in mod_log_config.
849 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
850 where HEAD response headers were being repeated twice for
851 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
852 problem in the http_header filter was exposed by the recent rewrite
853 of the content_length filter. [Taketo Kabe, Bill Stoddard]
855 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
856 restarts. A garbage pointer to a vhost's server_rec from the
857 previous generation was being left around under certain
858 conditions. [Greg Ames]
860 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
861 used to appear as '(none', without the closing paren.
862 [Günter Knauf <eflash@gmx.net>]
864 *) Improve the exports generating awk script. In the past, we had
865 work around problems in the awk script by avoiding some #if and
866 #ifdefs. This has bitten us many times in generating the exports.c
867 file. This improvement allows corrects the header file parsing.
868 [Sander Striker <striker@apache.org>]
870 Changes with Apache 2.0.21
872 *) Resolve the Win32 htpasswd bug, where a file that existed would be
873 overwritten, regardless of the -c flag.
874 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
876 *) Introduce connection sub-pools into ab. Truncating the lifetime
877 of these allocations means that ab no longer perpetually grows
878 its working set, running out of memory on large request attempts.
881 *) Make scoreboard creation a hook. This allows management
882 modules to have access to the scoreboard at the time that it is
883 created, and at every restart request.
884 [Cody Sherr <csherr@covalent.net>]
886 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
887 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
888 daemon index actually used in the scoreboard. I also
889 updated the pertinent calls. [Paul J. Reder]
891 *) Win32: Prevent listening sockets from being inherited by
892 the Apache child process, CGI scripts, rotatelog process
893 etc. If the Apache child process segfaults, any processes
894 that the child started are not reaped. Prior to this fix,
895 these processes inherited the listening sockets which sometimes
896 prevented the restarted Apache child process from accepting
897 connections (ie, the server would hang).
900 *) Provide vhost and request strings when ExtendedStatus is on.
903 *) Fix some issues with the pod and prefork: check the pod *after*
904 processing a connection so that a server processing a time-
905 consuming request bails out as soon as practical; when the
906 parent process wakes up a server process via connect(), use an
907 APR timeout on the connect() so that we don't hang for a long
908 time if there aren't server processes around to do accept().
909 [Jeff Trawick, Greg Ames]
911 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
912 spends a lot of time in apr_table_get calls. Using the default
913 httpd.conf, the tables for languages and charsets are somewhat
914 large, so the time spent scanning them on each request is
915 significant. Replacing the tables with hash tables provides
916 a nice speedup. [Brian Pane <bpane@pacbell.net>]
918 *) Add two functions to allow modules to access random parts of the
919 scoreboard. This allows modules compiled for one MPM to access the
920 scoreboard, even if it the server was compiled for another MPM.
921 [Harrie Hazewinkel <harrie@covalent.net>]
923 Changes with Apache 2.0.20
925 *) Fix problem in content-length filter where the filter would
926 buffer all the output from a CGI before sending any bytes
927 down the filter stack to the network. This problem would cause
928 significant memory consumption if the CGIs generated
929 lots of bytes. [Bill Stoddard]
931 *) Get non-blocking CGI pipe reads working with the bucket brigades.
934 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
937 *) Fix a bug in the threaded MPM that would cause it to kill off all
938 workers immediately after starting if the number of workers started
939 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
941 Changes with Apache 2.0.19
943 *) Fix problem with threaded MPM. The problem was that if each child
944 process was busy serving a single long-lived request and the server
945 was sent a graceful restart signal, the server would stop serving
946 requests. This would happen because each child process would wait to
947 die until the last thread was done, and the parent wouldn't spawn any
948 new children until a process died. Now, the parent looks at the fact
949 that the children are dying gracefully, and starts new children.
950 Those new children only start enough threads to compliment the number
951 of threads in the other child process that shares the same spot in
952 the scoreboard. In this way, we make sure to never go over
953 MaxClients. [Ryan Bloom]
955 *) modified mod_negotiation and mod_autoindex to speed up by almost a
956 factor of two on apr_dir_read()-enhanced platforms, such as Win32
957 and OS2, by calling ap_sub_request_lookup_dirent() with the results
958 already provided by apr_dir_read(). [William Rowe]
960 *) mod_file_cache is now more robust to filtering and serves requests
961 slightly more efficiently. [Cliff Woolley]
963 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
964 Module was calling ap_rwrite() followed by ap_rflush() but the
965 served content was not being displayed in the browser. Inspection
966 of the output stream revealed that the first data chunk was
967 missing the trailing CRLF required by the RFC. [Bill Stoddard]
969 *) apxs no longer generates ap_send_http_header() in the example handler
971 *) Fix an ab problem which could cause a divide-by-zero exception
972 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
973 [Ian Holsman <ianh@cnet.com>]
975 *) Solve case-insensitive platforms' confusion about negotiated
976 filenames, allowing files of differnt case to match in choosing
977 the document to serve. [William Rowe]
979 *) Fix brokenness when ThreadsPerChild is higher than the built-in
980 limit. We left ap_threads_per_child at the higher value which
981 led to segfaults when doing certain scoreboard operations.
984 *) Fix seg faults and/or missing output from mod_include. The
985 default_handler was using the subrequest pool for files and
986 MMAPs, even though the associated APR structures typically
987 live longer than the subrequest. [Greg Ames]
989 *) Extend mod_setenvif to support specifying regular expressions
990 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
991 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
992 will cause HAVE_TS to be set if any of the request headers begins
993 with "TS" and has a value that begins with any character in the
994 set [a-z]. [Bill Stoddard]
996 *) httpd children now re-bind themselves to a random CPU on
997 multiprocessor systems on AIX via bindprocessor() in 2.0.
998 [Victor J. Orlikowski]
1000 *) Fix htdigest. It would go into a loop in getline when adding
1001 a second user. [Bill Stoddard]
1003 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
1005 *) Automatically generate httpd.exp for AIX.
1006 DSOs now work again on AIX in 2.0
1007 [Victor J. Orlikowski]
1009 *) Add a new request hook, error_log. This phase allows modules
1010 to act on the error log string _after_ it has been written
1011 to the error log. The goal for this hook is to allow monitoring
1012 modules to send the error string to the monitoring agent.
1015 *) Modify mod_echo to make it use filters for input and output.
1016 [Ryan Morgan <rmorgan@covalent.net>]
1018 *) Extend mod_headers to support conditional driven Header
1019 add, append and set. Use SetEnvIf to set an envar and conditionally
1020 add/append/set headers based on this envar thusly:
1022 SetEnvIf TSMyHeader value HAVE_TSMyHeader
1023 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
1025 If the request contains header "TSMyHeader: value" then header
1026 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
1029 *) Extend mod_headers to support using format specifiers on Header
1030 add, append and set header values. Two format specifiers are supported:
1032 %t - reports, in UTC microseconds since the epoch, when the
1033 request was received.
1035 %D - reports the time, in microseconds, between when the request was
1036 received and the response sent.
1039 Header add MyHeader "This request served in %D microseconds. %t"
1041 results in a header being added to the response that looks like this:
1043 MyHeader: This request served in D=5438 microseconds. t=991424704447256
1047 *) Fix reset_filter(). We need to be careful how we remove filters.
1048 If we set r->output_filters to NULL, we also have to reset the
1049 connection's filters. [John Sterling]
1051 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
1053 *) Add a check to ap_die() to make sure the filter stack is sane and
1054 contains the correct basic filters when an error occurs. This fixes
1055 a problem where headers are not being sent on error. [John Sterling]
1057 *) New Header directive 'echo' option. "Header echo regex" will
1058 cause any headers received on the request that match regex to be
1059 echoed to (included in) the response headers.
1062 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
1063 This prevented the inclusion of apr_compat.h. PR #7773
1064 [Oleg Broytmann <phd@phd.pp.ru>]
1066 *) Moved util_uri to the apr-util library. This required a bunch of
1067 apr_name changes for the uri utility functions. [Justin Erenkrantz]
1069 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
1070 insert_filter phase so that other filters are not bypassed by default.
1073 *) Reimplement mod_headers as an output filter. mod_headers can now
1074 add custom headers to inbound requests using the RequestHeader directive
1075 and to responses using the same old Header directive. [Graham Leggett]
1077 Changes with Apache 2.0.18
1079 *) Fix command-line processing so that if a bad argument is specified
1080 Apache will exit. [Jeff Trawick]
1082 *) Change the make targets and rules to be consistent in all of the
1083 Apache-owned source trees. [Roy Fielding]
1085 *) Fix processing of the TRACE method. Previously we passed bogus
1086 parms to form_header_field() and it overlaid some vhost structures,
1087 resulting in a segfault in check_hostalias().
1088 [Greg Ames, Jeff Trawick]
1090 *) Win32: Add support for reliable piped logs. If the logging process
1091 goes down, Apache will automatically restart it. This function has
1092 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
1095 *) Do not start piped log processes during the config file
1096 preflight. This change also circumvents a problem on
1097 Windows where the rotatelog processes created during preflight
1098 was not getting cleaned up properly.
1101 *) add "Request Phase Participation" info to mod_info
1104 *) Make first phase changes to the scoreboard data structures in
1105 preparation for the rewriting of the scoreboard per my posted
1106 design notes. [Paul J. Reder]
1108 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
1109 and apr-util, allow it to be overridden by the configure command-line
1110 (default="--silent") and introduce LT_LDFLAGS to replace what we were
1111 formerly abusing as LTFLAGS. [Roy Fielding]
1113 *) Clean up the reporting of incorrect closing container tags.
1114 [Barrie Slaymaker <barries@slaysys.com>]
1116 *) Simplify the configure process by moving all libtool stuff to APR
1117 and moving hints.m4 inline. [Roy Fielding]
1119 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
1120 of functions used by mod_proxy for export in the DLL
1121 [Ian Holsman <IanH@cnet.com>]
1123 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
1124 request body from its stdin but no reqest body is being written to
1125 the cgi. [Jeff Trawick]
1127 *) mod_log_config: %c connection status incorrectly logged
1128 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
1131 *) Get mod_cern_meta working under Windows
1134 *) Create Files, and thus MMAPs, out of the request pool, not the
1135 connection pool. This solves a small resource leak that had us
1136 not closing files until a connection was closed. In order to do
1137 this, at the end of the core_output_filter, we loop through the
1138 brigade and convert any data we have into a single HEAP bucket
1139 that we know will survive clearing the request_rec.
1140 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
1143 *) Completely revamp configure so that it preserves the standard make
1144 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
1145 the configure additions to EXTRA_* variables. Also, allow the user
1146 to specify NOTEST_* values for all of the above, which eliminates the
1147 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
1148 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1149 avoid pointless duplications. Fix the order in which flags are given
1150 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1151 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1152 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1153 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1155 *) Get mod_tls to compile/work better on Windows. PR #7612
1156 [Bernhard Schrenk <b.schrenk@improx.com>]
1158 *) Fix shutdown/restart hangs in the threaded MPM.
1159 [Jeff Trawick, Greg Ames, Ryan Bloom]
1161 *) Removed the keptalive boolean from conn_rec because it is now only
1162 used by a single routine and can be replaced by a local variable.
1163 [Greg Stein, Ryan Bloom, Roy Fielding]
1165 *) Patch prefork to put enough of the signal processing back in so that
1166 signals are all handled properly now. The previous patch fixed the
1167 deadlock race condition, but broke the user directed signal handling.
1168 This fixes it to work the way it did before my previous prefork patch
1169 (primarily, SIGTERM is now working).
1171 *) Change how input filters decide how much data is returned to the
1172 higher filter. We used to use a field in the conn_rec, with this
1173 change, we use an argument to ap_get_brigade to determine how much
1174 data is retrieved. [Ryan Bloom]
1176 *) Fix seg fault at start-up introduced by Ryan's change to enable
1177 modules to specify their own logging tags. mod_log_config
1178 registers an optional function, ap_register_log_handler().
1179 ap_register_log_handler() was being called by http_core before
1180 the directive hash table was created. This patch creates the
1181 directive hash table before ap_register_log_handler() is
1182 registered as an optional function.
1183 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1185 *) Add ap_set_int_slot() function
1186 [John K. Sterling <sterling@covalent.net>]
1188 *) Under certain circumstances, Apache did not supply the
1189 right response headers when requiring authentication.
1190 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1191 (This is a port of the change that went into Apache 1.3.19.)
1193 *) Allow modules to specify their own logging tags. This basically
1194 allows a module to tell mod_log_config that when %x is encountered
1195 a specific function should be called. Currently, x can be any single
1196 character. It may be more useful to make this a string at some point.
1199 Changes with Apache 2.0.17
1201 *) If a higher-level filter handles the the byterange aspects of a
1202 request, then the byterange filter should not try to redo the
1203 work. The most common case of this happening, is a byterange
1204 request going through the proxy, and the origin server handles
1205 the byterange request. The proxy should ignore it.
1206 [Graham Leggett <minfrin@sharp.fm>]
1208 *) Changed the threaded mpm to have child_main join to each of the
1209 worker threads to make sure the kids are all gone before child_main
1210 exits after a signal (cleanup from perform_idle_server_maintenance).
1211 This is an extension of Ryans recent commit to make the child_main
1214 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1215 report if their threads are dynamic or static. Finally, this also
1216 implements a new API, ap_show_mpm, which returns the MPM that was
1217 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1219 *) Do not install the binaries from the support directory twice.
1220 [jun-ichiro hagino <itojun@iijlab.net>]
1222 *) The ap_f* functions should flush data to the filter that is passed
1223 in, not the the filter after the one passed in.
1224 [Ryan Morgan <rmorgan@covalent.net>]
1226 *) Make ab work again by changing its native types to apr types and formats.
1227 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1229 *) Move the byterange filter and all of the supporting functions back
1230 to the HTTP module. The byterange filter turned out to be very
1231 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1233 *) Make clean, distclean, and extraclean consistently according to the
1234 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1236 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1237 This may have been causing problems stopping processes in the threaded
1240 *) Fix content-length in mod_negotiation to a long int representation.
1243 *) Remove BindAddress from the default config file.
1244 [giles@nemeton.com.au]
1246 *) Allow module authors to add a module to their Apache build using
1247 --with-module, without re-running buildconf. The syntax is:
1248 --with-module=module_type:/path/to/module.c
1249 The configure script will copy the module.c file to
1250 modules/module_type, and it will be added to the relevant Makefiles.
1251 currently, this only works for static modules. [Ryan Bloom]
1253 *) Changes required to make prefork clean up idle children properly.
1254 There was a window during which a starting worker deadlocks when
1255 an idle cleanup arrives before it completes init. Apache then keeps
1256 trying to cleanup the same deadlocked worker forever (until higher
1257 pids come along, but it still will never reduce below the deadlocked
1258 pid). Thus the number of children would not reduce to the correct
1259 idle level. [Paul J. Reder]
1261 Changes with Apache 2.0.16
1263 *) Change the default installation directory to /usr/local/apache2,
1264 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1266 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1269 *) Get MaxRequestsPerChild working with the Windows MPM.
1272 *) Make generic hooks to work, with mod_generic_hook_import/export
1273 experimental modules. [Ben Laurie, Will Rowe]
1275 *) Fix segfaults for configuration file syntax errors such as
1276 "<Directory>" followed by "</Directory" and
1277 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1279 *) Cleanup the --enable-layout option of configure. This makes
1280 us use a consistent location for the config.layout file, and it
1281 makes configure more portable.
1282 [jun-ichiro hagino <itojun@iijlab.net>]
1284 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1285 csv/gnuplot format, rudimentary ssl support and various other tweaks
1286 to make results more true to what is measured. The upshot of this it
1287 turns out that 'ab' has often underreported the true performance of
1288 apache. Often by a order of magnitude :-) See talk/paper of Sander
1289 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1290 [Dirk-Willem van Gulik]
1292 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1293 storage leak this ensures that some unnecessary pipes are closed.
1296 *) Performance: Add quick_handler hook. This hook is called at the
1297 very beginning of the request processing before location_walk,
1298 translate_name, etc. This hook is useful for URI keyed content
1299 caches like Mike Abbott's Quick Shortcut Cache.
1302 *) top_module global variable renamed to ap_top_module [Perl]
1304 *) Move ap_set_last_modified to the core. This is a potentially
1305 controversial change, because this is kind of HTTP specific. However
1306 many protocols should be able to take advantage of this kind of
1307 information. I expect that headers will need one more layer of
1308 indirection for multi-protocol work, but this is a small step in
1309 the right direction. [Ryan Bloom]
1311 *) Enable mod_status by default. This matches what Apache 1.3 does.
1314 *) Add a ScriptSock directive to the default config file. This is
1315 only enabled when mod_cgid is used.
1316 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1318 Changes with Apache 2.0.15
1320 *) Untangled the buildconf script and eliminated the need for build's
1321 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1322 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1324 *) Win32: Don't accept more connections than we have worker threads
1328 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1329 to fork() new child processes.
1332 *) Fix a major security problem with double-reverse lookup checking.
1333 Previously, a client connecting over IPv4 would not be matched
1334 properly when the server had an IPv6 listening socket. PR #7407
1335 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1337 *) Change the way the beos MPM handles polling to allow it to stop and
1338 restart. Problem was the sockets being polled were being reset by
1339 the select call, so once it had accepted a connection it was no
1340 longer listening on the UDP socket we use for shutdown instructions.
1341 APR needs to be altered, patch on it's way. [David Reid]
1343 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1344 on error exit from ap_getline(). Some other code got upset because
1345 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1347 *) Handle ap_discard_request_body() being called more than once.
1348 [Greg Ames, Jeff Trawick]
1350 *) Get rid of an inadvertent close of file descriptor 2 in
1351 mod_mime_magic. [Greg Ames, Jeff Trawick]
1353 *) Add a hook, create_request. This hook allows modules to modify
1354 a request while it is being created. This hook is called for all
1355 request_rec's, main request, sub request, and internal redirect.
1356 When this hook is called, the the r->main, r->prev, r->next
1357 pointers have been set, so modules can determine what kind of
1358 request this is. [Ryan Bloom]
1360 *) Cleanup the build process a bit more. The Apache configure
1361 script no longer creates its own helper scripts, it just
1363 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1365 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1366 proxy requests. [Graham Leggett]
1368 *) Avoid using sscanf to determine the HTTP protocol number in
1369 the common case because sscanf is a performance hog. From
1370 Mike Abbot's Accelerating Apache patch number 6.
1371 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1373 *) Fix a security exposure in mod_access. Previously when IPv6
1374 listening sockets were used, allow/deny-from-IPv4-address rules
1375 were not evaluated properly (PR #7407). Also, add the ability to
1376 specify IPv6 address strings with optional prefix length on Allow
1377 and Deny. [Jeff Trawick]
1379 *) Enhance rotatelogs so that a UTC offset can be specified, and
1380 the logfile name can be formatted using strftime(3). (Brought
1381 forward from 1.3.) [Ken Coar]
1383 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1384 DuplicateHandle on an IOCompletionPort (a practice which
1385 MS "discourages"). The new model does not rely on associating
1386 the completion port with the listening sockets, thus the
1387 completion port can be completely managed within the child
1388 process. A dedicated thread accepts connections off the network,
1389 then calls PostQueuedCompletionStatus() to wake up worker
1390 threads blocked on the completion port.
1393 *) Bring forward the --suexec-umask option which allows the
1394 builder to preset the umask for suexec processes. [Ken Coar]
1396 *) Add a -V flag to suexec, which causes it to display the
1397 compile-time settings with which it was built. (Only
1398 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1400 *) Mod_include should always unset the content-length if the file is
1401 going to be passed through send_parsed_content. There is no to
1402 determine if the content will change before actually scanning the
1403 entire content. It is far safer to just remove the C-L as long
1404 as we are scanning it. [Ryan Bloom]
1406 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1407 request and not Proxy-Authenticate.
1408 [Graham Leggett <minfrin@sharp.fm>]
1410 Changes with Apache 2.0.14
1412 *) Fix content-length computation. We ONLY compute a content-length if
1413 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1414 or we already have all the data. [Ryan Bloom]
1416 *) Report unbounded containers in the config file. Previously, a typo
1417 in the </container> directive could result in the rest of the config
1418 file being silently ignored, with undesired defaults used.
1421 *) Make the old_write filter use the ap_f* functions for the buffering.
1424 *) Move more code from the http module into the core server. This
1425 is core code, basically the default handler, the default input
1426 and output filters, and all of the core configuration directives.
1427 All of this code is required in order for the server to work, with or
1428 without HTTP. The server is closer to working without the HTTP
1429 module, although there is still more to do. [Ryan Bloom]
1431 *) Fix a number of SGI compile warnings throughout the server. Fix some
1432 bad parameters to apr_bucket_read(). Fix a bad statement in
1433 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1434 consistently; we were mixing apr_time_t and time_t in invalid ways
1435 before. In load_file(), call apr_dso_error() instead of
1436 apr_strerror() so that we get a more specific string on some platforms.
1437 PR #6980 [Jeff Trawick]
1439 *) Allow modules to query the MPM about it's execution profile. This
1440 query API can and should be extended in the future, but for now,
1441 max_daemons, and threading or forking is a very good start.
1442 [Jon Travis <jtravis@covalent.net>]
1444 *) Modify mod_include to send blocks of data no larger than 9k.
1445 Without this, mod_include will wait until the whole file is parsed,
1446 or the first tag is found to send any data to the client.
1447 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1449 *) Fix mod_info, so that <Directory> and <Location> directives are
1450 not displayed twice when displaying the current configuration.
1451 [Ryan Morgan <rmorgan@covalent.net>]
1453 *) Add config directives to override DEFAULT_ERROR_MSG and
1454 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1455 [Dan Rench <drench@xnet.com>]
1457 *) Get mod_info building and loading on Win32. [William Rowe]
1459 *) Begin to move protocol independant functions out of mod_http. The goal
1460 is to have only functions that are HTTP specific in the http directory.
1463 Changes with Apache 2.0.13
1465 *) Don't assume that there will always be multiple calls to the byterange
1466 filter. It is possible that we will need to do byteranges with only
1467 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1469 *) Move the error_bucket definition from the http module to the
1470 core server. Every protocol will need this ability, not just
1473 Changes with Apache 2.0.12
1475 *) Modify mod_file_cache to save pre-formatted strings for
1476 content-length and last-modified headers for performance.
1477 [Mike Abbot <mja@trudge.engr.sgi.com>]
1479 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1480 [Jon Travis <jtravis@covalent.net>]
1482 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1483 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1485 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1486 without ever filling it out. This fixes PR 7271.
1487 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1488 Cliff Woolley <cliffwoolley@yahoo.com>]
1490 *) Add a couple of GCC attribute tags to printf style functions.
1491 [Jon Travis <jtravis@covalent.net>]
1493 *) Add the correct language tag for interoperation with the Taiwanese
1494 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1496 *) Migrate the perchild MPM to use the new apr signal child, and
1497 APR thread functions. [Ryan Bloom]
1499 *) Close one copy of the CGI's stdout before creating the new process.
1500 The CGI will still have stdout, because we have already dup'ed it.
1501 This keeps Apache from waiting forever to send the results of a CGI
1502 process that has forked a long-lived child process.
1503 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1505 *) Remove the rest of the pthreads functions from the threaded MPM.
1506 This requires the APR support for a signal thread that was just
1509 *) Make mod_dir use a fixup for sending a redirect to the browser.
1510 Before this, we were using a handler, which doesn't make much
1511 sense, because the handler wasn't generating any data, it would
1512 either return a redirect error code, or DECLINED. This fits the
1513 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1515 *) Make the threaded MPM use APR threads instead of pthreads.
1518 *) Get mod_tls to the point where it actually appears to work in all cases.
1521 *) implement --enable-modules and --enable-mods-shared for "all" and
1522 "most". [Greg Stein]
1524 *) Move the threaded MPM to use APR locks instead of pthread locks.
1527 *) Rename mpmt_pthread to threaded. This is more in line with the
1528 fact that mpmt_pthread shouldn't be using pthreads directly, and
1529 it is a smaller name that doesn't tie into anything.
1532 *) Rename the module structures so that the exported symbol matches
1533 the file name, and it is easier to automate the installation
1534 process (generating LoadModule directives from the module filenames).
1537 *) Remove the coalesce filter. With the ap_f* functions, this filter
1538 is no longer needed. [Ryan Bloom]
1540 Changes with Apache 2.0.11
1542 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1543 added feature of allowing a uid/gid per child process. If no
1544 uid/gid is specified, then Perchild behaves exactly like dexter.
1547 *) Get perchild building again. [Ryan Bloom]
1549 *) Don't disable threads just because we are using the prefork MPM.
1550 If somebody wants to compile without threads, they must now add
1551 --disable-threads to the configure command line. [Ryan Bloom]
1553 *) Begin to move the calls to update_child_status into common code, so
1554 that each individual MPM does not need to update the scoreboard itself.
1557 *) Allow mod_tls to compile under Unix boxes where openssl has been
1558 installed to the system include files.
1559 [Gomez Henri <new-httpd@slib.fr>]
1561 *) Cleanup the mod_tls configure process. This should remove any need
1562 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1563 configure doesn't check that yet. [Ryan Bloom]
1565 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1566 vital that you read modules/tls/README before attempting to build
1569 *) Fix a potential seg fault on all platforms. David Reid fixed this
1570 on BEOS, but the problem could happen anywhere, so we don't want
1571 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1573 *) Add new LogFormat directive, %D, to log time it takes to serve a
1574 request in microseconds. [Bill Stoddard]
1576 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1577 SetOutputFilter. This corresponds nicely with the other Set
1578 directives, which operate on containers while the Add* directives
1579 tend to work directly on extensions. [Ryan Bloom]
1581 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1582 functions for the buffering so that we don't need to compute
1583 the length of the headers before we actually create the header
1584 buffer. [Ryan Bloom]
1586 *) Allow filters to buffer data using the ap_f* functions. These have
1587 become macros that resolve directly to apr_brigade_*.
1590 *) Get the Unix MPM's to do a graceful restart again. If we are going
1591 to register a cleanup with ap_cleanup_scoreboard, then we have to
1592 kill the cleanup with the same function, and that function can't be
1593 static. [Ryan Bloom]
1595 *) Install all required header files. Without these, it was not
1596 possible to compile some modules outside of the server.
1599 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1600 forward from 1.3 to 2.0, we missed a single line, which broke regex
1601 aliases. [Ryan Bloom]
1603 *) We have a poor abstraction in the protocol. This is a temporary
1604 hack to fix the bug, but it will need to be fixed for real. If
1605 we find an error while sending out a custom error response, we back
1606 up to the first non-OK request and send the data. Then, when we send
1607 the EOS from finalize_request_protocol, we go to the last request,
1608 to ensure that we aren't sending an EOS to a request that has already
1609 received one. Because the data is sent on a different request than
1610 the EOS, the error text never gets sent down the filter stack. This
1611 fixes the problem by finding the last request, and sending the data
1612 with that request. [Ryan Bloom]
1614 *) Make the server status page show the correct restart time, and
1615 thus the proper uptime. [Ryan Bloom]
1617 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1618 should reduce the amount of duplicate code that is required to
1619 create CGI processes.
1620 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1622 *) ap_new_connection() closes the socket and returns NULL if a socket
1623 call fails. Usually this is due to a connection which has been
1624 reset. [Jeff Trawick]
1626 *) Move the Apache version information out of httpd.h and into release.h.
1627 This is in preparation for the first tag with the new tag and release
1628 system. [Ryan Bloom]
1630 *) Begin restructuring scoreboard code to enable adding back in
1631 the ability to use IPC other than shared memory.
1632 Get mod_status working on Windows again. [Bill Stoddard]
1634 *) Make mod_status work with 2.0. This will work for prefork,
1635 mpmt_pthread, and dexter. [Ryan Bloom]
1637 *) Correct a typo in httpd.conf.
1638 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1640 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1642 *) Get the correct IP address if ServerName isn't set and we can't
1643 find a fully-qualified domain name at startup.
1644 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1646 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1648 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1649 'extra' stat's for user/group since they should never occur, and now
1650 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1651 volumes. [William Rowe]
1653 *) Adopt apr features to simplify mod_includes. This changes the
1654 behavior of the USER_NAME variable, unknown uid's are now reported
1655 as USER_NAME="<unknown>" rather than the old user#000 result.
1656 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1658 *) Adopt apr features for simplifing mod_userdir, and accept the new
1659 Win32/OS2 exceptions without hiccuping. [William Rowe]
1661 *) Replace configure --with-optim option by using and saving the
1662 environment variable OPTIM instead. This is needed because configure
1663 options do not support multiple flags separated by spaces.
1666 *) Fix some byterange handling. If we get a byte range that looks like
1667 "-999999" where that is past the end of the file, we should return
1668 a PARTIAL CONTENT status code, and return the whole file as one big
1669 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1671 *) Make the error bucket a real meta-data bucket. This means that the
1672 bucket length is 0, and a read returns NULL data. If one of these
1673 buckets is passed down after the headers are sent, this data will
1674 just be ignored. [Greg Stein]
1676 *) The prefork MPM wasn't killing child processes correctly if a restart
1677 signal was received while the process was serving a request. The child
1678 process would become the equivalent of a second parent process. If
1679 we break out of the accept loop, then we need to do die after cleaning
1680 up after ourselves. [Ryan Bloom]
1682 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1683 restarts. [Ryan Bloom]
1685 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1686 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1687 performing very expensive owner, group and permission lookups
1688 and allows the server to function until these apr_finfo_t fields
1689 are implemented under Win32. [William Rowe]
1691 *) Support for typedsafe optional functions - that is functions exported by
1692 optional modules, which, therefore, may or may not be present, depending
1693 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1694 for sample code. [Ben Laurie]
1696 *) filters can now report an HTTP error to the server. This is done
1697 by sending a brigade where the first bucket is an error_bucket.
1698 This bucket is a simple bucket that stores an HTTP error and
1699 a string. Currently the string is not used, but it may be needed
1700 to output an error log. The http_header_filter will find this
1701 bucket, and output the error text, and then return
1702 AP_FILTER_ERROR, which informs the server that the error web page
1703 has already been sent. [Ryan Bloom]
1705 *) If we get an error, then we should remove all filters except for
1706 those critical to serving a web page. This fixes a bug, where
1707 error pages were going through the byterange filter, even though
1708 that made no sense. [Ryan Bloom]
1710 *) Relax the syntax checking of Host: headers in order to support
1711 iDNS. PR#6635 [Tony Finch]
1713 *) Cleanup the byterange filter to use the apr_brigade_partition
1714 and apr_bucket_copy functions. This removes a lot of very messy
1715 code, and hopefully makes this filter more stable.
1718 *) Remove AddModule and ClearModuleList directives. Both of these
1719 directives were used to ensure that modules could be enabled
1720 in the correct order. That requirement is now gone, because
1721 we use hooks to ensure that modules are in the correct order.
1724 *) When SuExec is specified, we need to add it to the list of
1725 targets to be built. If we don't, then any changes to the
1726 configuration won't affect SuExec, unless 'make suexec' is
1727 specifically run. [Ryan Bloom]
1729 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1730 the APR_XTHREAD argument to open a file for consumption by
1731 parallel threads on win32. [William Rowe]
1733 *) Correct a bug in determining when we follow symlinks. The code
1734 expected a stat -1 result, not an apr_status_t positive error.
1735 Also check if the APR_FINFO_USER fields are valid before we
1736 follow the link. [William Rowe]
1738 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1739 mpm_common.c. These functions are only valid on some platforms,
1740 so they should not be in the main-line code. [Ryan Bloom]
1742 *) Remove ap_chdir_file(). This function is not thread-safe,
1743 and nobody is currently using it. [Ryan Bloom]
1745 *) Do not try to run make depend if there are no .c files in the
1746 current directory, doing so makes `make depend` fail.
1749 *) Update highperformance.conf to work with either prefork or
1750 pthreads mpms. [Greg Ames]
1752 *) Stop checking to see if this is a pipelined request if we know
1753 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1754 This keeps us from making an extra read call when serving a 1.0
1755 request. [Ryan Bloom and Greg Stein]
1757 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1758 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1759 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1761 *) Fix the RFC number mentioned when complaining about a missing
1762 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1764 *) Fix an endless loop in ab which occurred when ab was posting
1765 and the server dropped the connection unexpectedly.
1768 *) Fix a segfault while handling request bodies in ap_http_filter().
1769 This problem has been seen with mod_dav usage as well as with
1770 requests where the body was just being discarded. [Jeff Trawick]
1772 *) Some adjustment on the handling and automatic setting (via
1773 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1774 add the capability to specify flags (NOTEST_CFLAGS and
1775 NOTEST_LDFLAGS) which are used to compile Apache, but
1776 not used during the configuration process. Useful for
1777 flags like "-Werror". [Jim Jagielski]
1779 *) Stop using environment variables to force debug mode or
1780 no detach. We now use the -D command line argument to
1781 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1782 [Greg Stein, Ryan Bloom]
1784 *) Change handlers to use hooks. [Ben Laurie]
1786 *) Stop returning copies of filenames from both apr_file_t and
1787 apr_dir_t. We pstrdup the filenames that we store in the
1788 actual structures, so we don't need to pstrdup the strings again.
1791 *) mod_cgi: Fix some problems where the wrong error value was being
1792 traced. [Jeff Trawick]
1794 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1797 *) Add generic hooks. [Ben Laurie]
1799 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1801 *) Fix a segfault caused by mod_ext_filter when the external filter
1802 program does not exist. [Jeff Trawick]
1804 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1805 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1806 was served through mod_charset_lite (or anything else that would
1807 create a transient bucket in this size range). ap_bucket_make_heap()
1808 silently failed (fixed), transient_setaside() discovered it, but
1809 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1811 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1812 is that some browsers send extra lines at the end of POST requests, and
1813 we don't want to delay sending data back to the user just because the
1814 browser isn't well behaved. [Ryan Bloom]
1816 *) Get SuEXEC working again. We can't send absolute paths to suExec
1817 because it refuses to execute those programs. SuEXEC also wasn't
1818 always recognizing configuration changes made using the autoconf
1821 *) Allow the buildconf process to find the config.m4 files in the correct
1822 order. Basically, we can now name config.m4 files as config\d\d.m4,
1823 and we will sort them correctly when inserting them into the build
1824 process. [Ryan Bloom]
1826 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1827 This also allows mod_cgid to use ap_os_create_priviledged_process,
1828 thus allowing for SuExec execution from mod_cgid. Currently, we do
1829 not support everything that standard SuExec supports, but at least
1830 it works minimally now. [Ryan Bloom]
1832 *) Allow SuExec to be configured from the ./configure command line.
1835 *) Update some of the docs in README and INSTALL to reflect some of
1836 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1838 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1839 need to call sendfile again. This gets us serving large files
1840 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1842 *) Get the support programs building cleanly again.
1843 [Cliff Woolley <cliffwoolley@yahoo.com>]
1845 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1846 current directory logic now backs up over bin/ to determine the
1847 server root from the Apache.exe path.
1849 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1850 loadable modules, dynamic libs are all named libfoo.dll, and the
1851 makefile.win populates the include, lib and libexec directories.
1853 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1854 Apache gets IPv6 listening sockets by default. Additionally, the
1855 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1856 numeric address strings (e.g., "Listen [fe80::1]:8080").
1859 *) Modify the install directory layout. Modules are now installed in
1860 modules/. Shared libraries should be installed in libraries/, but
1861 we don't have any of those on Unix yet. All install directories
1862 are modifyable at configure time. [Ryan Bloom]
1864 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1866 *) Get the functions in server/linked into the server, regardless of
1867 which modules linked into the server. This uses the same hack
1868 for Apache that we use for APR and apr-util to ensure all of the
1869 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1870 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1871 the scripts a bit easier.
1874 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1875 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1877 *) Get all of the auth modules to the point that they will install and
1878 be loadable into the server. Our new build/install mechanism expects
1879 that all modules will have a common name format. The auth modules
1880 didn't use that format, so we didn't install them properly.
1883 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1884 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1886 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1888 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1889 after the end of the response. [Ryan Bloom]
1891 *) Get byterange requests working with responses that do not have a
1892 content-length. Because of the way byterange requests work, we have to
1893 have all of the data before we can actually do the byterange, so we
1894 can compute the content-length in the byterange filter.
1897 *) Get exe CGI's working again on Windows.
1900 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1901 they keep track of whether or not their post config hook has been
1902 called before. Instead of a static variable (which is replaced when
1903 the DSO is loaded a second time), use userdata in the process pool.
1906 Changes with Apache 2.0a9
1908 *) Win32 now requires perl to complete the final install step for users
1909 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1910 and installs the conf, htdocs and htdocs/manual directories.
1913 *) Make mod_include use a hash table to associate directive tags with
1914 functions. This allows modules to implement their own SSI tags easily.
1915 The idea is simple enough, a module can insert it's own tag and function
1916 combination into a hash table provided by mod_include. While mod_include
1917 parses an SSI file, when it encounters a tag in the file, it does a
1918 hash lookup to find the function that implements that tag, and passes
1919 all of the relevant data to the function. That function is then
1920 responsible for processing the tag and handing the remaining data back
1921 to mod_include for further processing.
1922 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1924 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1925 fewer parameters: the local and remote socket addresses were removed
1926 from the parameter list because all required information is available
1927 via the APR socket. [Jeff Trawick]
1929 *) Distribution directory structure reorganized to reflect a
1930 normal source distribution with external install targets.
1933 *) The MPMs that need multiple segments of shared memory now create
1934 two apr_shmem_t variables, one for each shared memory allocation.
1935 the problem is that we can't determine how much memory will be required
1936 for shared memory allocations once we try to allocate more than one
1937 variable. The MM code automatically aligns the shared memory allocations,
1938 so we end up needing to pad the amount of shared memory we want based
1939 on how many variables will be allocated out of the shared memory segment.
1940 It is just easier to create a second apr_shmem_t variable, and two
1941 shmem memory blocks.
1944 *) Cleanup the export list a bit. This creates a single unified list of
1945 functions exported by APR. The export list is generated at configure
1946 time, and that list is then used to generate the exports.c file.
1947 Because of the way the export list is generated, we only export those
1948 functions that are valid on the platform we are building on.
1951 *) Enable logging the cookie with mod_log_config
1952 [Sander van Zoest <sander@covalent.net>]
1954 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1957 *) Added lib/aputil/ as a placeholder for utility functions which are not
1958 specific to the Apache HTTP Server (but do not make sense with APR).
1959 The first utility is "apu_dbm": a set of functions to work with DBM
1960 files. This first version can be compiled for SDBM or GDBM databases.
1963 *) Complete re-write of mod_include. This makes mod_include a filter that
1964 uses buckets directly. This has now served the FAQ correctly.
1965 [Paul Reder <rederpj@raleigh.ibm.com>]
1967 *) Allow modules to specify the first filter in a sub_request when
1968 making the sub_request. This keeps modules from having to change the
1969 output_filter immediately after creating the sub-request, and therefore
1970 skip the sub_req_output_filter. [Ryan Bloom]
1972 *) Update ab to accept URLs with IPv6 literal address strings (in the
1973 format described in RFC 2732), and to build Host header fields in
1974 the same format. This allows IPv6 literal address strings to be
1975 used with ab. This support has been tested against Apache 1.3 with
1976 the KAME patch, but Apache 2.0 does not yet work with this format
1977 of the Host header field. [Jeff Trawick]
1979 *) Accomodate an out-of-space condition in the piped logs and the
1980 rotatelogs.c code, and no longer churn log processes for this
1981 condition. [Victor J. Orlikowski]
1983 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1986 Changes with Apache 2.0a8
1988 *) Add a directive to mod_mime so that filters can be associated with
1992 *) Get multi-views working again. We were setting the path_info
1993 field incorrectly if we couldn't find the specified file.
1996 *) Fix 304 processing. The core should never try to send the headers
1997 down the filter stack. Always, just setup the table in the request
1998 record, and let the header filter convert it to data that is ready
2002 *) More fixes for the proxy. There are still bugs in the proxy code,
2003 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
2007 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
2010 *) APR: Add new apr_getopt_long function to handle long options.
2011 [B. W. Fitzpatrick <fitz@red-bean.com>]
2013 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
2014 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
2015 hostname resolution/address string parsing and building
2016 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
2017 of one of the apr_sockaddr_t structures for a socket. Change
2018 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
2020 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
2021 I have proxied pages with it, cleanup will commence soon.
2024 *) Make the proxy work with filters. This isn't perfect, because we
2025 aren't dealing with the headers properly. [Ryan Bloom]
2027 *) Do not send a content-length iff the C-L is 0 and this is a head
2028 request. [Ryan Bloom]
2030 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
2031 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
2033 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
2035 *) Get the default_handler to stop trying to deal with HEAD requests.
2036 The idea is to let the content-length filter compute the C-L before
2037 we try to send the data. If we can get the C-L correctly, then we
2038 should send it in the HEAD response.
2041 *) The Header filter can now determine if a body should be sent based
2042 on r->header_only. The general idea of this is that if we delay
2043 deciding to send the body, then we might be able to compute the
2044 content-length correctly, which will help caching proxies to cache
2045 our data better. Any handler that doesn't want to try to compute
2046 the content-length can just send an EOS bucket without data and
2047 everything will just work.
2050 *) Add the referer to the error log if one is available.
2051 [Markus Gyger <mgyger@itr.ch>]
2053 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
2054 change, the root of the configuration tree has been exposed to modules
2056 [Ryan Morgan <rmorgan@covalent.net>]
2058 *) Get the core_output_filter to use the bucket interface directly.
2059 This keeps us from calling the content-length filter multiple times
2060 for a simple static request.
2063 *) We are sending the content-type correctly now.
2064 [Ryan Bloom and Will Rowe]
2066 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
2067 a bogus bytes-sent value when the only thing being sent was trailers
2068 and writev() returned an error (or EAGAIN). [Jeff Trawick]
2070 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
2071 hints file to determine which platforms define
2072 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2075 *) APR: add apr_get_home_directory() [Jeff Trawick]
2077 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
2079 *) Not all platforms have INADDR_NONE defined by default. Apache
2080 used to make this check and define INADDR_NONE if appropriate,
2081 but APR needs the check too, and I suspect other applications will
2082 as well. APR now defines APR_INADDR_NONE, which is always a valid
2083 value on all platforms.
2084 [Branko Èibej <brane@xbc.nu>]
2086 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
2087 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
2089 *) Relax the syntax checking of Host: headers in order to support
2090 iDNS. PR#6635 [Tony Finch]
2092 *) When reading from file buckets we convert to an MMAP if it makes
2093 sense. This also simplifies the default handler because the
2094 default handler no longer needs to try to create MMAPs.
2097 *) BUFF has been removed from the main server. The BUFF code will remain
2098 in the code until it has been purged from the proxy module as well.
2101 *) Byteranges have been completely re-written to be a filter. This
2102 has been tested, and I believe it is working correctly, but it could
2103 doesn't work for the Adobe Acrobat plug-in. The output almost matches
2104 the output from 1.3, the only difference being that 1.3 includes
2105 a content-length in the response, and this does not.
2108 *) APR read/write functions and bucket read functions now operate
2109 on unsigned integers, instead of signed ones. It doesn't make
2110 any sense to use signed ints, because we return the error codes,
2111 so if we have an error we should report 0 bytes read or written.
2114 *) Always compute the content length, whether it is sent or not.
2115 The reason for this, is that it allows us to correctly report
2116 the bytes_sent when logging the request. This also simplifies
2117 content-length filter a bit, and fixes the actual byte-reporing
2118 code in mod_log_config.c
2121 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
2122 it says, because it was only used by EOS and FLUSH buckets. Since
2123 neither of those are required at the end of a brigade, this was
2124 really signifying FLUSH_THE_DATA, but that can be determined better
2125 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
2126 buckets now return a length of 0, which is actually the amount of data
2127 read, so they make more sense.
2130 *) Allow the core_output_filter to save some data past the end of a
2131 request. If we get an EOS bucket, we only send the data if it
2132 makes sense to send it. This allows us to pipeline request
2133 responses. As a part of this, we also need to allocate mmap
2134 buckets out of the connection pool, not the request pool. This
2135 allows the mmap to outlive the request.
2138 *) Make blocking and non-blocking bucket reads work correctly for
2139 sockets and pipes. These are the only bucket types that should
2140 have non-blocking reads, because the other bucket types should
2141 ALWAYS be able to return something immediately.
2144 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
2145 server, but use Ctrl+Break to initiate a graceful restart
2146 instead of duplicating behavior. [John Sterling]
2148 *) Patch mod_autoindex to set the Last-Modified header based on
2149 the directory's mtime, and add the ETag header. [William Rowe]
2151 *) Merge the 1.3 patch to add support for logging query string in
2152 such a way that "%m %U%q %H" is the same as "%r".
2155 *) Port three log methods from mod_log_config 1.3 to 2.0:
2156 CLF compliant '-' byte count, method and protocol.
2159 *) Add a new LogFormat directive, %c, that will log connection
2160 status at the end of the response as follows:
2161 'X' - connection aborted before the response completed.
2162 '+' - connection may be kept-alive by the server.
2163 '-' - connection will be closed by the server.
2166 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2167 Unicode file names and paths for Win32, and tag the Content-Type
2168 from mod_autoindex to reflect that charset if the the feature
2169 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2171 *) Compute the content length (and add appropriate header field) for
2172 the response when no content length is available and we can't use
2173 chunked encoding. [Jeff Trawick]
2175 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2176 so that content input filters get dechunked data when using
2177 the default handler. Also removed REQUEST_CHUNKED_PASS.
2180 *) Add mod_ext_filter as an experimental module. This module allows
2181 the administrator to use external programs as filters. Currently,
2182 only filtering of output is supported. [Jeff Trawick]
2184 *) Most Apache functions work on EBCDIC machines again, as protocol
2185 data is now translated (again). [Jeff Trawick]
2187 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2188 the EBCDIC support. They are noops on ASCII machines, so this
2189 type of translation doesn't have to be surrounded by #ifdef
2190 CHARSET_EBCDIC. [Jeff Trawick]
2192 *) Fix mod_include. tag commands work again, and the server will
2193 send the FAQ again. This also allows mod_include to set aside
2194 buckets that include partial buckets.
2195 [Ryan Bloom and David Reid]
2197 *) Add suexec support back. [Manoj Kasichainula]
2199 *) Lingering close now uses the socket directly instead of using
2200 BUFF. This has been tested, but since all we can tell is that it
2201 doesn't fail, this needs to be really hacked on.
2204 *) Allow filters to modify headers and have those headers be sent to
2205 the client. The idea is that we have an http_header filter that
2206 actually sends the headers to the network. This removes the need
2207 for the BUFF to send headers.
2210 *) Charset translation: mod_charset_lite handles translation of
2211 request bodies. Get rid of the xlate version of ap_md5_digest()
2212 since we don't compute digests of filtered (e.g., translated)
2213 response bodies this way anymore. (Note that we don't do it at
2214 all at the present; somebody needs to write a filter to do so.)
2217 *) Input filters and ap_get_brigade() now have a input mode parameter
2218 (blocking, non-blocking, peek) instead of a length parameter.
2221 *) Update the mime.types file to the registered media types as
2222 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2225 *) Namespace protect some macros declared in ap_config.h
2228 *) Support HTTP header line folding with input filtering.
2231 *) Mod_include works again. This should still be re-written, but at
2232 least now we can serve an SHTML page again.
2235 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2236 to both the BUFF and the socket in the conn_rec. Functions that
2237 want to use the BUFF can, functions that want to use the socket,
2238 can. They point to the same place.
2241 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2242 [Tomas "Ögren" <stric@ing.umu.se>]
2244 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2245 associated pool goes away. (APR pipes on OS/2 were already had this
2246 logic.) This resolvs a fatal file descriptor leak with CGIs.
2249 *) The final line of the config file was not being read if there was
2250 no \n at the end of it. This was caused by apr_fgets returning
2251 APR_EOF even though we had read valid data. This is solved by
2252 making cfg_getline check the buff that was returned from apr_fgets.
2253 If apr_fgets return APR_EOF, but there was data in the buf, then we
2254 return the buf, otherwise we return NULL.
2257 *) Piped logs work again in the 2.0 series.
2260 *) Restore functionality broken by the mod_rewrite security fix:
2261 rewrite map lookup keys and default values are now expanded
2262 so that the lookup can depend on the requested URI etc.
2263 PR #6671 [Tony Finch]
2265 *) Tighten up the syntax checking of Host: headers to fix a
2266 security bug in some mass virtual hosting configurations
2267 that can allow a remote attacker to retrieve some files
2268 on the system that should be inaccessible. [Tony Finch]
2270 *) Add a pool bucket type. This bucket is used for data allocated out
2271 of a pool. If the pool is cleaned before the bucket is destroyed, then
2272 the data is converted to a heap bucket, allowing it to survive the
2276 *) Add a flush bucket. This allows modules to signal that the filters
2277 should all flush whatever data they currently have. There is no way
2278 to actually force them to do this, so if a filter ignores this bucket,
2279 that's life, but at least we can try with this.
2282 *) Add an output filter for sub-requests. This filter just strips the
2283 EOS bucket so that we don't confuse the main request's core output
2284 filter by sending multiple EOS buckets. This change also makes sub
2285 requests start to send EOS buckets when they are finished.
2288 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2289 makes ap_bucket_destroy a return void, which is okay because it
2290 used to always return APR_SUCCESS, and nobody ever checked its
2291 return value anyway.
2292 [Cliff Woolley <cliffwoolley@yahoo.com>]
2294 *) Remove the index into the bucket-type table from the buckets
2295 structure. This has now been replaced with a pointer to the
2296 bucket_type. Also add some macros to test the bucket-type.
2299 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2300 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2301 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2302 All _VAR_ flavors changes to _DATA to be absolutely clear.
2305 *) Add support for /, //, //servername and //server/sharename
2306 parsing of <Directory> blocks under Win32 and OS2.
2307 [Tim Costello, William Rowe, Brian Harvard]
2309 *) Remove the function pointers from the ap_bucket type. They have been
2310 replaced with a global table. Modules are allowed to register bucket
2311 types and use then use those buckets.
2314 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2315 once we finish writing the request body to the cgi child process;
2316 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2317 worked without this change (for reasons I don't understand), but large
2318 ones didn't. [Jeff Trawick]
2320 *) Remove file bucket specific information from the ap_bucket type.
2321 This has been moved to a file_bucket specific type that hangs off
2322 the data pointer in the ap_bucket type.
2325 *) Input filtering now has a third argument. This is the amount of data
2326 to read from lower filters. This argument can be -1, 0, or a positive
2327 number. -1 means give me all the data you have, I'll deal with it and
2328 let you know if I need more. 0 means give me one line and one line
2329 only. A positive number means I want no more than this much data.
2331 Currently, only 0 and a positive number are implemented. This allows
2332 us to remove the remaining field from the conn_rec structure, which
2336 *) Big cleanup of the input filtering. The goal is that http_filter
2337 understands two conditions, headers and body. It knows where it is
2338 based on c->remaining. If c->remaining is 0, then we are in headers,
2339 and http_filter returns a line at a time. If it is not 0, then we are
2340 in body, and http_filter returns raw data, but only up to c->remaining
2341 bytes. It can return less, but never more.
2342 [Greg Ames, Ryan Bloom, Jeff Trawick]
2344 *) mod_cgi: Write all of the request body to the child, not just what
2345 the kernel would accept on the first write. [Jeff Trawick]
2347 *) Back out the change that moved the brigade from the core_output_filters
2348 ctx to the conn_rec. Since all requests over a given connection
2349 go through the same core_output_filter, the ctx pointer has the
2353 *) Fix another bug in the send_the_file() read/write loop. A partial
2354 send by apr_send would cause unsent data in the read buffer to
2355 get clobbered. Complete making send_the_file handle partial
2356 writes to the network.
2359 *) Fix a couple of type fixes to allow compilation on AIX again
2360 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2362 *) Fix bug in send_the_file() which causes offset to be ignored
2363 if there are no headers to send.
2366 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2367 filter. Useful for supporting Windows 9* with a binary
2368 compiled on Windows NT.
2371 Changes with Apache 2.0a7
2373 *) Reimplement core_output_filter to buffer/save bucket brigades
2374 across multiple calls to the core_filter. The brigade will be
2375 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2376 thresholds are hit or the EOS bucket is received.
2379 *) Create experimental filter (buffer_filter) that coalesces bytes
2380 into one large buffer before invoking the next filter in the
2381 chain. This filter is particularly useful with the current
2382 implementation of mod_autoindex when it inserted above the
2383 chunk_filter. mod_autoindex generates a lot of brigades that
2384 containing buckets holding just a few bytes each. The
2385 buffer_filter coalesces these buckets into a single large bucket.
2388 *) Add apr_sendfile() support into the core_output_filter.
2391 *) Add apr_sendv() support into the core_output_filter.
2394 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2395 [Mike Abbott <mja@sgi.com>]
2397 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2398 make much sense, because Apache uses buckets instead of BUFFs now.
2401 *) send_the_file now falls back to a read/write loop on platforms that
2402 do not have sendfile.
2403 [Ryan Bloom and Brian Havard]
2405 *) Install apachectl correctly, and substitute the proper values so
2406 that it works again. [Ryan Bloom]
2408 *) Better(??) handle platforms that lack sendfile().
2411 *) APR now has UUID generation/formatting/parsing support.
2414 *) Begin the http_filter. This is an input filter that understands
2415 the absolute basic amount required to parse an HTTP Request. The
2416 goal is to be able to split headers from request body before passing
2417 the data back to the other filters.
2420 *) Bring forward from 1.3.13 the config directory implementation
2423 *) install apxs if it is created
2426 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2427 conversions. [William Rowe]
2429 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2430 ap_add_output_filter(). [Jeff Trawick]
2432 *) Multiple build and configuration fixes
2435 -add datadir and localstatedir substitutions
2437 -fix logfilename misspelling
2438 -fix evaluation of installation dir variables and
2439 -replace $foobar by $(foobar) to be usefull in the makefile
2443 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2444 $CC_FOR_BUILD is still missing
2445 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2446 -add missing "AR=@AR@" to severaly Makefile.in's
2447 -cache result for "struct rlimit"
2448 -compile all helper programs with native and cross compiler
2449 and use the native version to generate header file
2450 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2452 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2454 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2456 *) Fix a bug where a client which only sends \n to delimit header
2457 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2458 message. Start working on ebcdic co-existance with input
2460 [William Rowe, Greg Ames]
2462 *) If mod_so is enabled in the server always create libexec, even
2463 if there are no modules installed in this directory. This is a
2464 requirement for APXS to work correctly.
2467 *) Connection oriented output filters are now stored in the
2468 conn_rec instead of the request_rec. This allows us to add the
2469 output filter in the pre-connection phase instead of the
2470 post_read_request phase, which keeps us from trying to write an
2471 error page before we have a filter to write to the network.
2472 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2474 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2475 mmap can be used across multiple buckets (default_handler with
2476 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2477 the mmap itself can't be associated with the bucket.
2480 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2483 *) Radical surgery to improve mod_isapi support under Win32.
2484 Includes a number of newer ServerSupportFunction calls, support
2485 for ReadClient (in order to retrieve POSTs greater than 48KB),
2486 and general bug fixes to more reliably load ISAPI .dll's and
2487 prevent leaking handle resources. Note: There are still
2488 discrepancies between IIS's and Apache's ServerVariables, and
2489 async calls are still not supported. Additional warnings are
2490 logged to facilitate debugging of unsupported ISAPI calls.
2493 *) Add input filtering to Apache. The basic idea for the input
2494 filters is the same as the ideas for output filters. The biggest
2495 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2496 should be called, and the order of execution for the filter itself is
2497 different. When writing an output filter, a brigade is passed in,
2498 and filters operate directly on that brigade, when done, they call
2499 ap_pass_brigade. Input filters are the exact opposite. Because input
2500 is not a push operation, filters first call ap_get_brigade. When this
2501 function returns, the input filter will be left with a valid brigade.
2502 The input filter should then operate on the brigade, and return.
2505 *) Fix building on BSD/OS using its native make. The build system
2506 falls back to the BSD .include directive on that host platform.
2509 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2510 SHA1 and plaintext password encodings. Make feature tests a
2511 bit more flexible. [William Rowe]
2513 *) Charset translation: mod_charset_lite handles output content
2514 translation in a filter. mod_charset_lite no longer ignores
2515 subrequests. A bunch of cruft related to BUFF's support for
2516 translating request and response bodies was removed.
2519 *) Move the addition of the CORE filter to the post_read_request
2520 hook in http_core.c. This removes the need to add the filter in
2521 multiple places and allows for an SSL module to be added much
2522 simpler. [Ryan Bloom]
2524 *) Fix a security problem that affects certain configurations of
2525 mod_rewrite. If the result of a RewriteRule is a filename that
2526 contains expansion specifiers, especially regexp backreferences
2527 $0..$9 and %0..%9, then it may be possible for an attacker to
2528 access any file on the web server. [Tony Finch]
2530 *) Fix a bug where errors that are detected during early request parsing
2531 don't produce visible HTTP error messages at the browser, because
2532 the core_filter wasn't present. [Greg Ames]
2534 *) Provide apr_socklen_t as a portability aid.
2535 [Victor J. Orlikowski]
2537 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2538 as well as a comment arg to the add, adduser and update cmds.
2539 update allows the user to clear or preserve pw/groups/comment.
2540 Fixed a bug in dbmmanage that prevented the check option from
2541 parsing a password followed by :group... text. Corrected the
2542 seed calcualation for Win32 systems, and added -lsdbm support.
2545 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2548 *) Avoid a segfault when parsing .htaccess files. An
2549 uninitialized tree pointer was passed to ap_build_config().
2552 *) Change the way that inet_addr & inet_network are checked for
2553 in APR's configure process to allow BeOS BONE to correctly
2554 find them. With this change BeOS BONE now builds from source
2555 with no problems. [David Reid]
2557 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2558 the end of the parameters to execve() was stored in the wrong
2559 location, overlaying the storage beyond the newargs[] array and
2560 also passing uninitialized storage to execve(), which would
2561 sometimes fail with EFAULT. [Jeff Trawick]
2563 *) Fix a bug parsing configuration file containers. With a sequence
2564 like this in the config file
2566 <IfModule mod_kilroy.c>
2569 <IfModule mod_lovejoy.c>
2574 the second container would be terminated at the blank line due to
2575 sediment in the buffer from reading the prior </IfModule> and an
2576 error message would be generated for the real </IfModule> for the
2577 second container. Also due to this problem, any two characters
2578 could be used for "</" in the close of a container.
2581 *) ap_add_filter prototype changed to remove the ctx pointer. The
2582 pointer still remains in the filter structure, but it can not be
2583 a part of the ap_add_filter prototype. The reason is that when
2584 the core uses AddFilter to add a filter to the stack it doesn't
2585 know how to allocate the ctx pointer, or even how much memory should
2586 be allocated. The filters will have to be responsible for allocating
2587 the ctx memory when they need it.
2590 *) Add an AddFilter directive. This directive takes a list of filters
2591 that should be activated for the requested resource.
2594 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2595 some other platforms). [Jeff Trawick]
2597 *) Modify mod_include to be a filter. Currently, it has only been tested
2598 on actual files, but it should work for CGI scripts too.
2601 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2602 writes. apr_flush() for Unix: handle interrupted writes.
2605 *) NameVirtualHost can now take "*" as an argument instead of
2606 an IP address. This allows you to create a purely name-based
2607 virtual hosting server that does not have any IP addresses in
2608 the configuration file and which ignores the local address
2609 of any connections. PR #5595, PR #4455 [Tony Finch]
2611 *) Fix some compile warnings in mod_mmap_static.c
2612 [Mike Abbott <mja@sgi.com>]
2614 *) Fix chunking problem with CGI scripts. The general problem was that
2615 the CGI modules were adding an EOS bucket and then the core added an
2616 EOS bucket. The chunking filter finalizes the chunked response when it
2617 encounters an EOS bucket. Because two EOS buckets were sent, we
2618 finalized the response twice. The fix is to make sure we only send one
2619 EOS, by utilizing a flag in the request_rec.
2622 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2623 and Win32. Previously, the first read from an apr_file_t set up via
2624 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2626 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2627 bucket, instead of using BUFF's and ap_r*.
2630 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2631 [Mike Abbott <mja@sgi.com>]
2633 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2634 code to use APR file's directly instead of going through BUFFs.
2637 *) Fix compile break on some platforms for mod_mime_magic.c
2638 [John K. Sterling <sterling@covalent.net>]
2640 *) Fix merging of AddDefaultCharset directive.
2641 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2643 *) Minor revamp of the rlimit sections of code. We now test
2644 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2645 is now "available" even if the platform doesn't support
2646 the rlimit family (it's just a noop though). [Jim Jagielski]
2648 *) Migrate the pre-selection of which MPM to use for specific
2649 platforms to hints.m4, which contains (or should contain)
2650 all platform specific "hints". [Jim Jagielski]
2652 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2655 *) Add tables with non-string/binary values to APR.
2658 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2661 *) Update PCRE to version 3.2. [Ryan Bloom]
2663 *) Change the way buckets' destroy functions are called so that
2664 they can be more directly used when changing the type of a
2665 bucket in place. [Tony Finch]
2667 *) Add generic support for reference-counting the resources used by
2668 buckets, and alter the HEAP and MMAP buckets to use it. Change
2669 the way buckets are initialised to support changing the type of
2670 buckets in place, and use it when setting aside TRANSIENT buckets.
2671 Change the implementation of TRANSIENT buckets so that it can be
2672 mostly shared with IMMORTAL buckets, which are now implemented.
2675 Changes with Apache 2.0a6
2677 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2679 *) Add a chunking filter to Apache. This brings us one step closer
2680 to removing BUFF. [Ryan Bloom]
2682 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2683 added to the stack is the last filter to be called. [Ryan Bloom]
2685 *) Apache 2.0 has been completely documented using Scandoc. The
2686 docs can be generated by running 'make docs'. [Ryan Bloom]
2688 *) Add filtered I/O to Apache. This is based on bucket brigades,
2689 Currently the buckets still use BUFF under the covers, but that
2690 should change quickly. The only currently written filter is the
2691 core filter which just calls ap_bwrite. [The Apache Group]
2693 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2694 built with thread support. [Jeff Trawick]
2696 *) Abort configuration if --with-layout was specified and there's
2697 no layout definition file. [Ken Coar]
2699 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2701 *) Add support for extension methods for the Allow response header
2702 field, and an API routine for accessing r->allowed and the
2703 list of extension methods in a unified manner. [Ken Coar]
2705 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2706 [Rob Simonson <simo@us.ibm.com>]
2708 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2709 APACHE_XLATE builds. [Jeff Trawick]
2711 *) A configuration file parsing problem was fixed. When the
2712 configuration file started with an IfModule/IfDefine container,
2713 only the last statement in the container would be retained.
2716 Changes with Apache 2.0a5
2718 *) Perchild is serving pages after passing them to different child
2719 processes. There are still a lot of bugs, but this does work. I
2720 have made requests against the same installation of Apache, and had
2721 different servers use different user IDs to serve the responses.
2722 This change moves to using socketpair instead of an AF_UNIX socket.
2725 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2726 It can't seem to pass between child processes yet, but I think we
2727 are closer now than before. This moves us back to using Unix
2728 Domain Sockets. [Ryan Bloom]
2730 *) libapr functions and types renamed with apr_ prefix.
2731 #include "apr_compat.h" for 1.3.x backwards compat
2734 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2735 return the right information on the local socket address.
2736 [Gregory Nicholls <gnicholls@level8.com>]
2738 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2739 [Gregory Nicholls <gnicholls@level8.com>]
2741 *) Add an option to not detach from the controlling terminal without
2742 going into single process mode. This allows for much easier
2743 debugging of the process startup code. [Ryan Bloom]
2745 *) ab: don't use perror() to report the failure of an APR function.
2748 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2749 scoreboard on graceful restarts.
2752 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2753 An invalid ap_proc_t was passed to ap_create_process().
2756 *) Allow modules to register filters. Those filters are still
2757 never called, but this is a step in the right direction.
2758 [Ryan Bloom and Greg Stein]
2760 *) Register the mod_cgid daemon process for cleanup so that it is
2761 killed at termination if it does not die when the parent gets
2762 SIGTERM. This change is to fix occasional problems where the
2763 process stays around. Bugs in similar logic in mod_rewrite and
2764 mod_include were also fixed. [Jeff Trawick]
2766 *) Fix a bug in the time handling. Basically, we were imploding a time
2767 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2768 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2769 uses those two fields to adjust the time value. Because of the HTTP
2770 spec, both of those values can be zero'ed out safely. This fixes
2771 the bug correctly. [Ryan Bloom]
2773 *) Fix a couple of place in the Windows code where the wrong error
2774 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2776 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2778 *) Added the APR_EOL_STR macro for platform dependent differences in
2779 logfiles and other raw text (such as all APR files). Fixes logfiles
2780 not terminated with cr/lf sequences in Win32. [William Rowe]
2782 *) Move all strings functions in APR to src/lib/apr/strings and create
2783 apr_strings.h for the prototypes. [Ryan Bloom]
2785 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2786 to repeat the syscall until we stop getting EINTR. I noticed a
2787 related problem at termination (SIGTERM) on FreeBSD when using
2788 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2789 implementation work properly with child init. Previously, ap_lock()
2790 was essentially a no-op because all children were using different
2791 locks and thus nobody ever blocked. [Jeff Trawick]
2793 *) The htdocs/ tree has been moved out of the CVS source tree into
2794 a separate area for easier development. This has NO EFFECT on
2795 end-users or Apache installations. [Ken Coar]
2797 *) Integrate the mod_dav module for WebDAV protocol handling. This
2798 adds the dav and dav_fs modules, the SDBM library, and additional
2799 XML handling utilities. [Greg Stein]
2801 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2804 *) Update the lib/expat-lite/ library (bring forward changes from
2805 the Apache 1.3 repository). [Greg Stein]
2807 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2808 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2810 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2811 machines where sendfile is detected, but nobody has written ap_sendfile.
2812 [Dave Hill <ddhill@zk3.dec.com>]
2814 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2816 *) ab would start up more connections than needed, then quit when the
2817 desired number were finished. Also fixed a logic error involving
2818 ab keepalives. [Victor J. Orlikowski]
2820 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2821 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2822 timeouts (i.e, if a timeout was specified, the pipe reverted to
2823 a full blocking pipe). Now the behaviour is more in line with
2824 Unix non-blocking pipes.
2827 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2828 cache open file handles along with accept socket reuse enables
2829 Apache 2.0 to serve non-keepalive requests for static files at
2830 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2831 and Apache 2.0 will serve almost 1200 rps on my system).
2834 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2835 supports two config directives, mmapfile (same behavious as
2836 mod_mmap_static) and cachefile. Use the cachefile directive
2837 to cache open file handles. This directive only works on systems
2838 that have implemented the ap_sendfile API. cachefile works today
2839 on Windows NT, but has not been tested on any flavors of Unix.
2842 *) Cleanup the configuration. With the last few changes the
2843 configuration process automatically:
2844 inherits information about how to build from APR. Allowing
2845 APR to inform Apache that it should or should not use -ldl
2847 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2848 based on the threading model
2850 Apache calls APR's configure process before finishing it's
2851 configuration processing, allowing for more information flow
2856 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2857 with non-zero argument makes the socket non-blocking. BeOS and
2858 OS/2 already worked this way. [Jeff Trawick]
2860 *) ap_close() now calls ap_flush() for buffered files, so write
2861 operations work a whole lot better on buffered files.
2864 *) Fix error messages issued from MPMs which explain where to change
2865 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2868 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2869 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2870 now the way that the blocking state of a pipe is manipulated.
2871 ap_block_pipe() is gone. [Jeff Trawick]
2873 *) Correct the problem where the only local host name that the IP stack
2874 can discover are 'undotted' private names. If no fully qualified
2875 domain name can be identified, the default ServerName will be set to
2876 the machine's IP address string. A warning is always provided if the
2877 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2879 *) Repair problems with config file processing which caused segfault
2880 at init when virtual hosts were defined and which caused ServerName to
2881 be ignored when there was no valid DNS setup. [Jeff Trawick]
2883 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2885 *) Add ap_sendfile implementation for AIX
2886 [Victor J. Orlikowski]
2888 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2889 apr_network_io.h, and apr_thread_proc.h.
2890 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2892 *) Bring the allocation and pool debugging code back into a working
2893 state. This will need to be tested as so far it's only been used on
2896 *) Change configuration command setup to be properly typesafe when in
2897 maintainer mode. Note that this requires a compiler that can initialise
2898 unions. [Ben Laurie]
2900 *) Turn on buffering for config file reads. Part of this was to
2901 repair buffered I/O support in Unix and implement buffered
2902 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2904 *) Win32: Fix problem where UTC offset was not being set correctly
2905 in the access log. Problem reported on news group by Jerry Baker.
2908 *) Fix segfault when reporting this type of syntax error:
2909 "</container> without matching <container> section", where
2910 container is VirtualHost or Directory or whatever.
2913 *) Prevent the source code for CGIs from being revealed when using
2914 mod_vhost_alias and the CGI directory is under the document root
2915 and a user makes a request like http://www.example.com//cgi-bin/cgi
2916 as reported in <news:960999105.344321@ernani.logica.co.uk>
2919 *) Add support for the new Beos NetwOrking Environment (BONE)
2922 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2923 final input char is incomplete; ap_bwrite_xlate() now handles
2924 incomplete final input chars. [Jeff Trawick]
2926 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2927 that a bhalfduplex call occurs before logging or else DNS and
2928 such can delay the last packet of the response. [Dean Gaudet]
2930 *) Some syscall reduction in APR on unix -- don't seek when setting
2931 up an mmap; and don't fcntl() more than once per socket.
2934 *) When mod_cgid is started as root, the cgi daemon now switches
2935 to the configured User/Group (like other httpd processes)
2936 instead of continuing as root. [Jeff Trawick]
2938 *) The prefork MPM now uses an APR lock for the accept() mutex.
2939 It has not been getting a lock at all recently. httpd -V now
2940 displays APR's selection of the lock mechanism instead of the
2941 symbols previously respected by prefork. [Jeff Trawick]
2943 *) Change the mmap() feature test to check only for existence.
2944 The previous check required features not used by Apache.
2947 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2948 sometimes mangled. The len parm to accept() was not
2949 initialized, leading sometimes to an endless loop of failed
2950 accept() calls on OS/390 and anywhere else that failed the call
2951 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2952 instead of declaring it ourselves to fix a compilation problem
2953 on Solaris. [Jeff Trawick]
2955 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2957 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2959 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2961 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2962 initialization if ALLOC_DEBUG is defined; no known symptom
2963 otherwise. [Jeff Trawick]
2965 *) Fix typo in configure script when checking for mod_so. bash
2966 doesn't seem to have a problem but /bin/sh on Solaris does.
2967 Symptom: "./configure: test: unknown operator =="
2970 *) Rebind the Win32 NT and 9x services control into the MPM.
2971 All console, WinNT SCM and Win9x pseudo-service control code is
2972 now wrapped within the WinNT MPM.
2975 *) Make a copy of getenv("PATH") before storing for later use. Some
2976 getenv() implementations use the same storage for successive calls.
2977 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2979 *) Server Tokens work in 2.0 again. This also propogates the change
2980 to allow just the product name in the server string using
2984 Changes with Apache 2.0a4
2986 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2987 won't need to call it. [Greg Ames, Jeff Trawick]
2989 *) Move pre_config hook call to between configuration read and config
2990 tree walk. This allows all modules to implement pre_config hooks
2991 and know that they will be called at an appropriate time.
2994 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2997 *) Add pre-config hooks back to all modules.
3000 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
3001 ContentDigest enabled and we can't/don't mmap the file.
3004 *) We now report the correct line number for syntax errors in config
3005 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
3007 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
3008 related bugs, and changed shmem/locking to use apr API. Shared-mem
3009 is currently disabled, however, because of problems with graceful
3010 restarts. [Ronald Tschalär]
3012 *) Fix corruption of IFS variable in --with-module= handling.
3013 Depending on the user's shell or customization thereof, there
3014 would be errors generating ap_config_auto.h later in the configure
3015 procedure. [Jeff Trawick]
3017 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
3018 isn't used (as in 1.3), except that on Unix it is now logged via
3019 ap_log_rerror() instead of by the child having STDERR_FILENO refer
3020 to the error log. [Greg Ames, Jeff Trawick]
3022 *) Add '-D' argument processing for run time configuration defines.
3025 *) Organize http_main.c as independent code, such that no code or
3026 global data is exported from it. WIN32 will dynamically link it
3027 to the server core, so this will prevent mutual dependency.
3030 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
3031 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
3034 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
3035 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
3037 *) Add mod_charset_lite for configuring character set translation.
3040 *) Add '-n' option to htpasswd to make it print its user:pw record
3041 on stdout rather than having to frob a text file. [Ken Coar]
3043 *) Fix saferead. Basically, we flush the output buffer if a read on the
3047 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
3048 a conversion is single-byte only. [Jeff Trawick]
3050 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
3051 the BeOS 5.0 documentation says that shutdown doesn't work yet.
3054 *) Fix some minor errors where pid was being manipulated as an int
3055 instead of the portable pid_t. [Roy Fielding]
3057 *) Fix some error log prints that were printing the pointer to a
3058 structure rather than the pid within the structure.
3059 [Jeff Trawick, Roy Fielding]
3061 *) ab: Fix a command-line processing bug; track bad headers in
3062 err_response; support reading headers up to 2K.
3063 [Ask Bjoern Hansen <ask@valueclick.com>]
3065 *) Fix ap_resolve_env() so that it handles new function added in a prior
3066 alpha (see "Added the capability to do ${ENVVAR} constructs in the
3067 config file.") as well as the constructs used by mod_rewrite.
3068 [Paul Reder <rederpj@raleigh.ibm.com>]
3070 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
3072 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
3073 APR to perform translation, instead of accessing the hard-coded tables
3074 in 1.3's ebcdic.c. [Jeff Trawick]
3076 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
3079 *) Add the ability to hook into the config file reading phase. Basically
3080 if a directive is specified EXEC_ON_READ, then when that directive is
3081 read from the config file, the assocaited function is executed. This
3082 should only be used for those directives that must muck with HOW the
3083 server INTERPRETS the config. This should not be used for directives
3084 that re-order or replace items in the config tree. Those changes should
3085 be made in the pre-config step.
3088 *) Add mod_example to the build system.
3091 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
3092 byte character sets. [Jeff Trawick]
3094 *) Pick up various EBCDIC fixes from 1.3 (from Martin
3095 Kraemer and Oliver Reh originally according to the change log).
3098 *) Fix a couple of problems in RFC1413 support (controlled by the
3099 IdentityCheck directive). Apache did not build the request string
3100 properly and more importantly Apache would loop forever if the
3101 would-be ident server dropped the connection before sending a
3102 properly terminated response. [Jeff Trawick]
3104 *) apxs works in 2.0.
3107 *) Reliable piped logs work in 2.0.
3110 *) Introduce a hash table implementation into APR to be used for
3111 replacing tables and other random data structures in Apache.
3114 *) Add some more error reporting to htpasswd in the case of problems
3115 generating or accessing the temporary file. Also, pass in a
3116 buffer if the implementation knows how to use it (i.e., if L_tmpnam
3117 is defined). [Ken Coar]
3119 *) Configure creates config.nice now containing your configure
3120 options. Syntax: ./config.nice [--more-options]
3123 *) Fix various return code problems in APR on Win32. For most of
3124 these, APR was returning APR_EEXIST instead of GetLastError()/
3125 WSAGetLastError(). [Jeff Trawick]
3127 *) Make piped logs work again in version 2.0
3130 *) Add VPATH support to UNIX build system of Apache and APR.
3133 *) Fix ap_tokenize_to_argv to respect the const arguments that are
3137 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
3138 Patch submitted to author.
3141 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
3142 /sbin in PATH on FreeBSD (all submitted to rse previously)
3145 *) Fix building Pthread-based MPMs on OpenBSD
3146 [Sascha Schumann] PR#26
3148 *) Fix ap_readdir() problem on systems where d_name[] field in
3149 struct dirent is declared with only one byte. (This problem only
3150 affected multithreaded builds.) This caused a segfault during
3151 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3152 least). [Jeff Trawick]
3154 *) Fix some make-portability problems on at least Tru64, Irix
3156 [Sascha Schumann] PR#18, PR#39
3158 *) Add ap_sigwait() to support old-style sigwait() on systems
3159 like OS/390 and UnixWare.
3162 *) Add POSIX-thread flags for more platforms.
3165 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3166 (on Unix, at least) to handle resolver errors. Fix a bug in
3167 the definition of APR_ENOMEM so that ap_strerror() can spit
3168 out the correct error message for it.
3171 Changes with Apache 2.0a3
3173 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3176 *) API: *HOOK* macros now have an AP_ prefix
3179 *) Win32: Eliminate redundant calls to initialize winsock.
3180 [Tim Costello <timcostello@ozemail.com.au>]
3182 *) Fix bugs initializing ungetchar for pipes.
3183 [Chia-liang Kao <clkao@CirX.ORG>]
3185 *) The ab program in the src/support directory is now portable using
3189 *) Support directory is being compiled when the server is built
3192 *) The configure option --with-program-name has been added to allow
3193 developers to rename the executable at configure time. This also
3194 changes the name of the config files to match the executable's name.
3197 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3198 containing version numbers. [Martin Pool]
3200 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3201 Unix; access_log and error_log now created with these perms; non-
3202 Unix is unaffected [Jeff Trawick]
3204 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3205 Replaced more magic numbers with MD5_DIGESTSIZE.
3206 [William Rowe, Roy Fielding]
3208 *) Win32: Get mod_auth_digest compiling and added to the Windows
3209 build environment. Not tested and I'd be suprised if it
3210 actually works. [Bill Stoddard]
3212 *) Revamp the Win32 make environment. Makefiles have been removed and
3213 Apache.dsw created to bring together all the pieces. Create new file
3214 os/win32/BaseAddr.ref to define module base addresses (to prevent
3215 dll relocation at start-up).
3216 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3218 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3219 of the \015, \012, and \015\012 constants with macros.
3220 [Greg Ames <gregames@us.ibm.com>]
3222 *) Add ap_xlate_open() et al for translation of text between different
3223 character sets. The initial implementation requires iconv().
3226 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3227 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3229 *) CGI output is being timed out now.
3232 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3233 is used by the new apr file. There is no reason to create a new file
3234 with the same lifetime as the original file.
3237 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3238 module base addresses. This will help shooting seg faults
3239 in the field. [William Rowe <wrowe@lnd.com>]
3241 *) Update Apache on Windows documentation. Add new document
3242 describing how to compile Apache on Windows.
3243 [William Rowe <wrowe@lnd.com>]
3245 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3246 microseconds instead of seconds. Some storage leaks and other
3247 minor bugs in related code were fixed. [Jeff Trawick]
3249 *) Win32: First cut at getting mod_isapi working under 2.0
3250 [William Rowe <wrowe@lnd.com>]
3252 *) First stab at getting mod_auth_digest working under 2.0
3253 quick change summary:
3254 - moved the random byte generation (ap_generate_random_bytes) into APR
3255 - now uses ap_time_t
3256 - compiles and runs on linux
3258 [Brian Martin <bmartin@penguincomputing.com>]
3260 *) Win32: Move the space stripping of physical service names
3261 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3262 unresolved symbol. Add dependency checking to the
3263 CreateService call to ensure TCPIP and AFP (winsock) is started
3265 [William Rowe <wrowe@lnd.com>]
3267 *) Win32: Add code to perform latebinding on functions that may
3268 not exist on all levels of Windows where Apache runs. This
3269 is needed to allow Apache to start-up on Win95/98. All calls
3270 to non portable functions should be protected with
3271 ap_oslevel checks to prevent runtime segfaults.
3272 [William Rowe <wrowe@lnd.com>]
3274 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3276 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3278 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3279 This addresses PR 1623. Still need to address timing out runaway
3280 CGI scripts. [Bill Stoddard]
3282 *) Win32: Make ap_stat Windows 95/98 friendly
3283 [William Rowe <wrowe@lnd.com>]
3285 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3286 always fail. Need to initialise the dwOSVersionInfoSize member of the
3287 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3290 The patch also enhances ap_get_oslevel (and the associated enum) to
3291 handle selected service packs for NT4, and adds recognition for
3292 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3293 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3294 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3296 *) Get mod_rewrite building and running, and mod_status building for Win NT
3297 [Allan Edwards <ake@raleigh.ibm.com>]
3299 *) Patch to port mod_auth_db to the 2.0 api and also to support
3300 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3301 2.7.7. It should work with version 1 as well but I haven't tested it.
3302 [Brian Martin <bmartin@penguincomputing.com>]
3304 *) Get APR DSO code working under Windows. Includes cross platform
3306 [Tim.Costello@BTFinancialgroup.com]
3308 *) Fix some of the Windows APR time functions.
3311 *) FAQ changes related to tidying up historical documents on the web site.
3312 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3314 *) Move Windows DSO code into APR.
3317 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3318 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3319 at build time. At this point, the server will not compile on Windows because
3320 of the recent DSO commits. Fixing those next.
3321 [Bill Rowe & Bill Stoddard]
3323 *) Added error checking for file I/O APR routines.
3324 [Jon Travis <jtravis@covalent.net>]
3326 *) APR: Don't use the values of resolver error codes for the
3327 corresponding APR error codes. On Unix and Win32, return the
3328 proper APR error code after a resolver error. [Jeff Trawick]
3330 Changes with Apache 2.0a2
3332 *) Renamed the executable back to httpd on all platforms other
3336 *) Allow BeOS to survive restarts, log properly and a few
3337 small things it had problems with due to the way it setup
3338 users and groups. [David Reid]
3340 *) Get mod_rewrite working with APR locks
3341 [Paul Reder <rederpj@raleigh.ibm.com>]
3343 *) Actually remove the sempahore when the lock cleanup routine
3344 is called on BeOS. [David Reid]
3346 *) Clear hook registrations between reads of the config file.
3347 When DSOs are unloaded and re-loaded the old hook pointers may
3348 no longer be valid. This fix eliminates potential segfaults.
3349 [Allan Edwards <ake@raleigh.ibm.com>]
3351 *) Fix a problem with Sigfunc not being defined or bypassed
3352 if sigaction() wasn't found. [Jim Jagielski]
3354 *) Fix the locking mechanism on BSD variants. They now use fcntl
3355 locks. This allows the server to start and serve pages.
3358 *) First cut at getting the Win32 installer to work
3359 [William Rowe <wrowe@lnd.com>]
3361 *) Get htpasswd compiling under Windows
3362 [William Rowe <wrowe@lnd.com>]
3364 *) Change the log message for a bind() failure to show the
3365 interface and port number. [Jeff Trawick]
3367 *) Import the documentation from 1.3.12 and bring parts of it
3368 up-to-date with respect to the changes that have occurred
3372 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3373 now logged correctly on BeOS.
3376 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3377 Makefile.win includes the same user interface as the old
3379 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3381 *) Win32 exec now uses COMSPEC environment string for command
3382 shell path resolution.
3383 [William Rowe <wrowe@lnd.com>] PR#3715
3385 *) Win32: ap_connect() was not returning correct error condition
3387 [Allen Prescott <allen@clanprescott.com>]
3389 *) Win32: ap_open() was broken on Win9x because an NT-specific
3390 flag was passed to CreateFile. ap_puts() added an unnecessary
3392 [Jeff Trawick <trawick@us.ibm.com>]
3394 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3395 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3396 confusing ee/et name and made all extensions language/dialect
3397 rather than country reflecting. Changed example files to
3398 explicit reflect the ISO charset and added a few common
3399 ones to the example config [dirkx]
3401 *) Extend external module capability. To use this, you call
3402 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3405 *) Backported the various "default charset" fixes from 1.3.12,
3406 including the AddDefaultCharset directive. [Jim Jagielski]
3408 *) Added the capability to do ${ENVVAR} constructs in the
3409 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3410 it does this on a line by line basis; i.e. if the envvar
3411 expands to something with spaces you have to protect it
3412 by adding quotes around it (Unless of course you expect it
3413 to contains more than one argument. Alternatively you
3414 can compile it on a per token basis; which is what people
3415 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3416 hampers fancier hacks.
3417 [Dirk-Willem van Gulik]
3419 *) Changed the 'ErrorDocument' syntax in that it NO longer
3420 supports the asymetric
3422 ErrorDocument 301 "Some message
3424 Note the opening " quote, without a closing quote. It now
3425 has either the following syntaxes
3427 ErrorDocument XXX /local/uri
3428 ErrorDocument XXX http://valid/url
3429 ErrorDocument XXX "Some Message"
3431 The recognition heuristic is: if it has a space it
3432 is a message. If it has no spaces and starts with a /
3433 or is a valid URL then treat it that way. Otherwise it
3434 is assumed to be a message.
3436 This breaks backward compatibility but makes live a hell
3437 of a lot easier for GUI's and config file parsers.
3438 [Dirk-Willem van Gulik]
3440 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3441 syntax into a 'on' or 'off' syntax. As it currently is the
3442 only non nesting token which uses NO_ARGS and thus is an
3443 absolute pain for any config interface automation. This
3444 breaks backward compatibility. [Dirk-Willem van Gulik]
3446 *) Add ability to add external modules to the build process. This is
3447 done with --with-module=/path/to/module. Modules can only be added
3448 as static modules at this point.
3451 Changes with Apache 2.0a1
3453 *) Fix FreeBSD 3.3 core dump.
3454 Basically, ap_initialize() needs to get called before
3455 create_process(), since create_process() passes op_on structure
3456 to semop() to get a lock, but op_on isn't initialized until
3457 ap_initialize() calls setup_lock(). Here is a slight
3458 rearrangement to main() which calls ap_initialize() earlier...
3459 [Jeff Trawick <trawick@us.ibm.com>]
3461 *) Enable Apache to use sendfile/TransmitFile API
3462 [Bill Stoddard, David Reid, Paul Reder]
3464 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3468 *) Make file I/O and network I/O writev/sendv APIs consistent.
3469 Eliminate use of ap_iovec_t and use Posix struct iovec.
3470 Use seperate variable on ap_writev to set the number of iovecs
3471 passed in and number of bytes written.
3474 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3475 with ap_create_file_iol(). ap_create_file_iol() requires that
3476 the file be opened prior to the call using ap_open().
3479 *) Port mod_include and mod_cgi to 2.0
3480 [Paul Reder, Bill Stoddard]
3482 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3483 bytes_read/bytes_written is always valid (never -1). Plus
3484 some fixes to buff.c to correct problems introduced by the
3485 errno => ap_status_t changes a while back. Plus a fix to
3486 chunked encoding introduced right at the beginning of 2.0.
3489 *) Revamped UNIX build system to use autoconf and libtool.
3490 [Manoj Kasichainula, Sascha Schumann]
3492 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3494 *) More rigorous checking of Host: headers to fix security problems
3495 with mass name-based virtual hosting (whether using mod_rewrite
3496 or mod_vhost_alias).
3497 [Ben Hyde, Tony Finch]
3499 *) Add back support for UseCanonicalName in <Directory> containers.
3500 [Manoj Kasichainula]
3502 *) Added APLOG_STARTUP log type. This allows us to write an error
3503 message without any of the date and time information. As a part
3504 of this change, I also removed all of the calls to fprintf(stderr
3505 and replaced them with calls to ap_log_error using APLOG_STARTUP
3506 writing to stderr is no longer portable, because we don't direct
3507 stderr to the error log on all platforms.
3510 *) Convert error logging functions to take errno as an argument.
3511 This makes our error logs more portable, because some Windows API's
3512 don't set errno. This change allows us to still output a valid
3513 message on all of our platforms.
3516 *) mod_mime_magic runs in 2.0-dev now.
3517 [Paul Reder <rederpj@raleigh.ibm.com>]
3519 *) sendfile has been added to APR.
3520 [John Zedlewski <zedlwski@Princeton.EDU>]
3522 *) buff.c has been converted to no longer use errno.
3523 [Manoj Kasichainula]
3525 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3526 interface adaption to APR functions did it. [Martin Kraemer]
3528 *) Support DSOs properly on 32-bit HP-UX 11.0
3529 [Dilip Khandekar <dilip@cup.hp.com>]
3531 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3532 [Ralf S. Engelschall]
3534 *) Cleaned APR build environment integration and bootstrap APR
3535 automatically for developers from src/Configure.
3536 [Ralf S. Engelschall]
3538 *) Fixed building of src/support/htpasswd.c
3539 [Ralf S. Engelschall]
3541 *) When generating the Location: header, mod_speling forgot
3542 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3545 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3547 *) Change all pools to APR contexts. This is the first step to
3548 incorporating APR into Apache. [Ryan Bloom]
3550 *) Move "handler not found" warning message to below the check
3551 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3552 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3554 *) Support line-continuation feature in config.option file and
3555 allow the loading of multiple option sections at once via
3556 ``--with-option=<section1>,<section2>,...''
3557 [Ralf S. Engelschall]
3559 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3561 Changes with Apache MPM
3563 *) Use asynchronous AcceptEx() and a completion port to accept and
3564 dispatch connections to threads in Windows NT/2000.
3567 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3570 *) Implement the APACI --with-option facility
3571 (per default used the config.option file).
3572 [Ralf S. Engelschall]
3574 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3576 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3577 Replace pre_connection module call with a register_hook call and
3578 implement pre_connection as a hook. The intent is that these hooks will
3579 be extended to allow Apache to be multi-protocol, and also to allow the
3580 calling order to be specified on a per-hook/per-module basis.
3583 *) Implement mpm_* methods as "modules". Each method gets its own
3584 subdir in src/modules (eg: src/modules/prefork). Selection
3585 of method uses Rule MPM_METHOD. [Jim Jagielski]
3587 *) Port the hybrid server from the apache-apr repository as
3588 mpm_mpmt_pthread. [Manoj Kasichainula]
3590 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3591 amongst the unix MPMs.
3593 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3594 signal handling for the new world order. [Dean Gaudet]
3596 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3597 of alloc.c for now. [Dean Gaudet]
3599 *) Handle partial large writes correctly. [Ben Laurie]
3601 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3602 based on IP/port. [Ben Laurie]
3604 *) Port a bunch of modules to the new module structure.
3605 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3607 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3609 *) Basic restructuring to introduce the MPM concept; includes various
3610 changes to the module API... better described by
3611 docs/initial_blurb.txt. [Dean Gaudet]
3613 Changes with Apache pthreads
3615 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3616 buff operations (generally over a network).
3617 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3619 *) Created http_accept abstraction. Added 4 new functions (not exported):
3620 init_accept(), begin_accepting_requests(), get_request(),
3621 stop_accepting_requests() [Bill Stoddard]
3623 *) Fix to ap_rprintf call that allows mod_info to work properly.
3624 [James Morris <jmorris@intercode.com.au>]
3626 *) user and ap_auth_type fields were moved from connection_rec to
3627 request_rec. [Ryan Bloom]
3629 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3630 needed in a threaded server.
3632 *) Initial pthread implementation from from Dean's apache-nspr code.
3633 [Bill Stoddard, Ryan Bloom]
3636 Changes with Apache 1.3.9
3638 *) Remove bogus error message when a redirect doesn't set Location.
3639 Instead, use an empty string to avoid coredump if the error message
3640 was supposed to include a location. [Roy Fielding]
3642 *) Don't allow configure to include mod_auth_digest unless it is
3643 explicitly requested, even if the user asked for all modules.
3646 *) Translate module names to dll names for OS/2 so that they are no more
3647 than 8 characters long and have an extension of "dll" instead of "so".
3650 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3651 Fix test-compile check to check for randbyte instead of trand32.
3652 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3653 and tweak to make Amaya happier. [Ronald Tschalär]
3655 *) Ensure that the installed expat include files are world readable,
3656 just like the other header files. [Martin Kraemer]
3658 *) Fixed generated AddModule adjustments in APACI's `configure' script
3659 in order to allow (new) modules like mod_vhost_alias to be handled
3660 correctly (which was touched by the adjustments for mod_alias).
3661 [Ralf S. Engelschall]
3663 *) For binary builds, add -R flag to apachectl to work around the lack of
3664 an absolute path to the ./libexec directory where the libhttp.ep file
3665 is needed for SHARED_CORE architectures. [Randy Terbush]
3667 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3668 problem observed by some Win95/98 users where they get CGI script
3669 output sent to the console. [Bill Stoddard]
3671 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3672 routines are now called ap_base64* and are 'plain' (i.e., no
3673 pool access or anything clever). Inside util.c the routines acting
3674 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3675 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3676 now but deprecated. [dirkx]
3678 *) Clean up the base64 and SHA1 additions and make sure they are
3679 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3680 files. [Roy Fielding]
3682 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3683 checking. Allow compiling on VS 6.0. [Randy Terbush]
3685 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3687 *) Use TestCompile to search for the truerand library (rather than blindly
3688 assuming its existence). If it is not found, complain (but do not
3689 exit - yet). [Martin Kraemer]
3691 *) We forgot to add the new exported function names to
3692 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3694 *) Add description of -T command-line option to usage().
3695 [Ralf S. Engelschall]
3697 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3698 searched only AFTER libap has been searched, because libap needs
3699 some symbols from libos. [Martin Kraemer]
3701 *) Fix conflict with original mod_digest related to the symbol of the
3702 module dispatch list (which has to be unique for DSO and follow the
3703 usual conventions for the installation procedure).
3704 [Ralf S. Engelschall]
3706 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3707 for other platforms as well. [Martin Kraemer]
3709 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3710 types by AP_LONG and replace reference to renamed variable 'ubuf'
3711 by 'buffer'. [Martin Kraemer]
3713 Changes with Apache 1.3.8 [not released]
3715 *) Flush the output buffer immediately after sending an error or redirect
3716 response, since the result may be needed by the client to abort a
3717 long data transfer or restart a series of pipelined requests.
3718 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3720 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3721 [Ian Turner <iant@sequent.com>] PR#4735
3723 *) Local struct mmap in http_core.c conflicted with system structure
3724 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3726 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3727 [Ronald Tschalär <ronald@innovation.ch>]
3729 *) Fix a memory leak where the module counts were getting messed
3730 up across restarts. [David Harris <dharris@drh.net>]
3732 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3733 properly in mod_access.
3734 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3736 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3737 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3739 *) PORT: Support for compaq/tandem/com.
3740 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3742 *) Added SHA1 password encryption support to easy migration from
3743 Netscape servers. See support/SHA1 for more information.
3744 Caused the separation of ap_md5.c into md5, sha1 and a general
3745 ap_checkpass.c with just a validate_passwd routine. Added a
3746 couple of flags to support/htpasswd. Some reuse of the to64()
3747 function; hence renamed to ap_to64().
3748 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3750 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3751 with ASCII/EBCDIC conversions in "ident" query.
3752 [David McCreedy <McCreedy@us.ibm.com>]
3754 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3755 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3756 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3758 *) Fix SIGSEGV on some systems because the Vary fix below included
3759 a call to table_do with a variable argument list that was not
3760 NULL terminated. Replaced with better implementation. [Roy Fielding]
3762 Changes with Apache 1.3.7 [not released]
3764 *) The "Vary" response header field is now sanitised right before
3765 the header is sent back to the client. Multiple "Vary" fields
3766 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3767 "Vary: host, negotiate, host, accept-language") are reduced to
3768 single instances. This is a better solution than the force-no-vary
3769 one (which is still valid for clients that can't cope with Vary
3770 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3772 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3774 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3775 least on Linux and FreeBSD for now.
3778 *) Win32: More apache -k restart work. Restarts are now honored
3779 immediately and connections in the listen queue are -not- lost.
3780 This is made possible by the use of the WSADuplicateSocket()
3781 call. The listeners are opened in the parent, duplicated, then
3782 the duplicates are passed to the child. The original listen sockets
3783 are not closed by the parent across a restart, thus the listen queue
3785 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3787 *) Fix handling of case when a client has sent "Expect: 100-continue"
3788 and we are going to respond with an error, but get stuck waiting to
3789 discard the body in the pointless hope of preserving the connection.
3790 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3792 *) Fix 'configure' to work correctly with SysV-based versions of
3793 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3795 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3796 built-in values. Add "-e" option which works like -i but doesn't
3797 install the DSO; useful for editing httpd.conf with apxs. Fix
3798 editing code so that multiple invocations of apxs -a will not
3799 create duplicate LoadModule/AddModule entries; apxs can now be
3800 used to re- enable/disable a module. [Wilfredo Sanchez]
3802 *) Win32: Update the server to use Winsock 2. Specifically, link with
3803 ws2_32.lib rather than wsock32.lib. This gives us access to
3804 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3805 Win 95 users may need to update their TCP/IP stack to pick up
3806 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3807 [Bill Stoddard stoddard@raleigh.ibm.com]
3809 *) Win32: Redirect CGI script stderr (script debug info) into the
3810 error.log when CGI scripts fail. This makes Apache on Win32
3811 behave more like Unix.
3812 [Bill Stoddard stoddard@raleigh.ibm.com]
3814 *) Fixed `httpd' usage display: -D was missing.
3815 [Ralf S. Engelschall] PR#4614
3817 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3818 [Ralf S. Engelschall] PR#4561, PR#4562
3820 *) OS/2: Fix problem with accept lock semaphores where server would die with
3821 "OS2SEM: Error 105 getting accept lock. Exiting!"
3822 [Brian Havard] PR#4505
3824 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3825 [Randy Terbush <randy@covalent.net>]
3827 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3828 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3830 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3831 command potentially _is_ GCC. [Ralf S. Engelschall]
3833 *) Fix apxs build issues on AIX
3834 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3836 *) DocumentRoot Checking: Under previous versions, when Apache
3837 first started up, it used to do a stat of each DocumentRoot to
3838 see if it existed and was a directory. If not, then an error
3839 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3840 does not exist, you will get error messages in error_log. If
3841 the '-t' command line option is used (to check the configuration)
3842 the check of DocumentRoot IS performed. An additional command
3843 line option, '-T', has been added if you want to avoid the
3844 DocumentRoot check even when checking the configuration.
3847 *) Win32: The query switch "apache -S" didn't exit after showing the
3848 vhost settings. That was inconsistent with the other query functions.
3849 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3851 *) Win32: Changed behaviour of apache -k restart.
3852 Previously, the server would drain all connections in the stack's
3853 listen queue before honoring the restart. On a busy server, this
3854 could take hours. Now, a restart is honored almost immediately.
3855 All connections in Apache's queues are handled but connections in
3856 the stack's listen queue are discarded. Restart triggered by
3857 MaxRequestPerChild is unchanged.
3858 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3860 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3861 the accept loop. Good for a 5% performance boost. Cleaned up
3862 parent/child process management code.
3863 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3865 *) Added ceiling on file size for memory mapped files.
3866 [John Giannandrea <jg@meer.net>] PR#4122
3868 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3869 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3870 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3872 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3873 use this at least for Expat. [Ralf S. Engelschall]
3875 *) Allow .module files to specify libraries with Lib:.
3878 *) Allow SetEnvIf[NoCase] to test environment variables as well
3879 as header fields and request attributes. [Ken Coar]
3881 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3882 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3884 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3885 never accepted into any standard, and it opens up certain DoS
3886 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3888 *) TestCompile updated. We can now run programs and output the
3889 results during the Configure process. [ Jim Jagielski]
3891 *) The source is now quad (long long) aware as needed. Specifically,
3892 the Configure process determines the correct size of off_t and
3893 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3894 provides for the 'q' format qualifier (if quads are not available,
3895 'q' is silently "demoted" to long). [Jim Jagielski]
3897 *) When the username or password fed to htpasswd is too long, include the
3898 size limit in the error message. Also report illegal characters
3899 (currently only ':') in the username. Add the size restrictions
3900 to the man page. [Ken Coar]
3902 *) Fixed the configure --without-support option so it doesn't result in
3903 an infinite loop. [Marc Slemko]
3905 *) Piped error logs could cause a segfault if an error occured
3906 during configuration after a restart.
3907 [Aidan Cully <aidan@panix.com>] PR#4456
3909 *) If a "Location" field was stored in r->err_headers_out rather
3910 than r->headers_out, redirect processing wouldn't find it and
3911 the server would core dump on ap_escape_html(NULL). Check both
3912 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3913 if Location isn't set. [Doug MacEachern, Ken Coar]
3915 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3916 of the Expat 1.0.2 distribution. [Greg Stein]
3918 *) Replace regexec() calls with calls to a new API stub function
3919 ap_regexec(). This solves problems with DSO modules which use the regex
3920 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3922 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3923 environment variables can be set according to the protocol version
3924 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3926 *) Add DSO support for OpenStep (Mach 4.2) platform.
3927 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3929 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3930 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3932 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3933 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3935 *) Better DSO flags recognition on NetBSD platforms using ELF.
3936 [Todd Vierling <tv@pobox.com>] PR#4310
3938 *) Always log months in english format for %t in mod_log_config.
3939 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3941 *) Support for server-parsed and multiview-determined ReadmeName and
3942 HeaderName files in mod_autoindex. Removed the restriction on
3943 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3944 routines will deal with the access issues. (It's now possible to
3945 have {site|group|project|customer|...} wide readmes and headers.)
3946 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3949 *) When stat() fails, don't assume anything about the contents of
3950 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3952 *) It's OK for a semop to return EINTR, just loop around and try
3953 again. [Dean Gaudet]
3955 *) Fix configuration engine re-entrant hangups, which solve a
3956 handful of problems seen with mod_perl <Perl> configuration sections
3957 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3959 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3960 by default when building with APACI; allow for platform-specific
3961 variable defaults in configure. [Wilfredo Sanchez]
3963 *) Do setgid() before initgroups() in http_main; some platforms
3964 zap the grouplist when setgid() is called. This was fixed in
3965 suexec earlier, but the main httpd code missed the change.
3966 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3968 *) Add recognition of .tgz as a gzipped tarchive.
3969 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364

3977 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3980 *) Fix minor but annoying bug with the test for Configuration.tmpl
3981 being newer than Configuration so that it is less likely to fail
3982 when using APACI and shadow sources. [Wilfredo Sanchez]
3984 *) PORT: Add initial support for Mac OS (versions 10.0 and
3985 greater). Use Mac OS X Server layout for now. Clean up dyld code
3986 in unix/os.c, and don't install the dyld error handlers, which
3987 are no longer needed in Mac OS. [Wilfredo Sanchez]

3993 *) Modify mod_autoindex's handling of AddDescription so that the
3994 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3996 *) Add functionality to the install-bindist.sh script created by
3997 binbuild.sh to use tar when copying distribution files to the
3998 serverroot. This allows upgrading an existing installation
3999 without nesting the new distribution in the old.
4001 install-bindist.sh now detects the local perl5 path to install
4002 apxs and dbmmanage with proper path to perl interpreter.
4004 Add an install-binsupport target which copies the source files
4005 for apxs and dbmmanage to bindist to allow these scripts to
4006 be properly installed relative to the destination serverroot.

4034 value of the DirectoryIndex directive is a single dot. Also likely
4035 to happen for anyother values of DirectoryIndex that will map back

4119 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
4122 *) Correct an apparent typo: on the Windows and MPE platforms, the
4123 htpasswd utility was limiting passwords to only 8 characters.
4126 *) EBCDIC platforms: David submitted patches for two bugs in the
4127 MD5 digest port for EBCDIC machines:
4128 a) the htdigest utility overwrote the old contents of the digest file
4129 b) the Content-MD5 header value (ContentDigest directive) was wrong
4130 when the returned file was not converted from EBCDIC, but was a
4131 binary (e.g., image file) in the first place.
4132 [David McCreedy <mccreedy@us.ibm.com>]
4134 *) support/htpasswd now permits the password to be specified on the
4135 command line with the '-b' switch. This is useful when passwords
4136 need to be maintained by scripts -- particularly in the Win32
4137 environment. [Ken Coar]
4139 *) Win32: Win32 multiple services patch. Added capability to install and
4140 run multiple copies of apache as individual services.
4143 apache -n apache1 -i -f c:/httpd.conf
4144 Installs apache as service 'apache1' and associates c:/httpd.conf
4147 Starts apache1 service.
4149 Stops apache1 service
4152 apache -n apache2 -i
4153 Installs apache as service 'apache2'. httpd.conf is located under
4154 the default server root (/apache/conf/httpd.conf).
4156 Starts apache2 service.
4159 apache -n apache3 -i -d c:/program files/apache

4169 *) Correct the signed/unsigned character handling for the MD5 routines;
4170 mismatches were causing compilation problems with gcc -pedantic and
4171 in the TPF cross-compilation. [Ken Coar]
4173 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4174 a roughly 5 fold speed up. [Brian Havard]
4176 *) proxy ftp: instead of using the hardwired string "text/plain" as
4177 a fallback type for files served by the ftp proxy, use the
4178 ap_default_type() function to determine the configured type.
4179 This allows for special configurations like
4180 <Directory proxy:ftp://some.host>
4181 DefaultType gargle/blurb
4183 Additionally, add the Content-Encoding: header to FTP proxy replies
4184 when the encoding is defined (by the AddEncoding directive).
4185 Because it was missing, it was almost impossible to browse compressed
4186 files using the FTP proxy (works now perfectly in Communicator).
4187 The ftp proxy now also returns the Date: and Server: header lines (if not
4188 much else... This code is "somewhat" broken) like normal requests do.
4191 *) Be more smart in APACI's configure script when determining the UID/GID
4192 for User/Group directives and use the determined UID/GID to initialize
4193 the permissions on the proxycachedir.
4194 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4196 *) Changed the forking-prior-to-cleanup in the proxy module to first
4197 check wether it actually needs to collect garbage. This reduces
4198 the number of fork()s from one/request to just the odd one an hour.
4199 [Dirk-Willem van Gulik]

4229 methods can be access controlled. [Roy Fielding] PR#3821
4231 *) Added PassAllEnv; makes server's entire environment available
4232 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4234 *) ap_uuencode() always added two trailing '='s and encoding of
4235 8 bit characters on a machine with signed char may produced
4236 incorrect results. Additionally ap_uuencode() should now
4237 work correctly on EBCDIC platforms.
4238 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4240 *) WIN32: Binary installer now runs the configuration DLL before
4241 the reboot prompt (which is only given if MSVCRT.DLL system
4242 DLL is new or updated). This should avoid the configuration
4243 directory being empty after installation. [Paul Sutton]
4244 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

4267 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4268 for 8-bit safeness. [Dean Gaudet]
4270 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4271 because SPARCs have a small machine-specific maximum size for the Global
4272 Offset Table which is often exceeded when compiling one of the larger
4273 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4275 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

4296 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
4297 possible buffer overflows. [Ralf S. Engelschall]
4299 *) Remove no longer used non-API function ap_single_module_init().
4300 [Ralf S. Engelschall]
4302 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4305 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4306 to make platform installations easier. [Wilfredo Sanchez]
4308 *) In configure, do not append the target name to the directory path if
4309 the path already contains "apache". [Ralf S. Engelschall]
4311 *) SIGPIPE is now ignored by the server core. The request write routines
4312 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4313 correctly check for output errors and mark the connection as aborted.
4314 Replaced many direct (unchecked) calls to ap_b* routines with the
4315 analogous ap_r* calls. [Roy Fielding]
4317 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4318 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4319 Furthermore map lookups for non-existent keys are now cached as well.
4320 Additionally "txt" maps are now parsed with simple string functions
4321 instead of using ap_pregcomp(). As a side effect a bug that prevented
4322 the usage of keys containing the "," character was fixed.
4323 The changes drastically improve the performance when large rewrite maps
4325 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4327 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4328 other than GET, and const'd the definition of method in request_rec.

4333 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4334 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4336 *) Add %V to mod_log_config, this logs the hostname according to the
4337 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4338 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4340 *) Add support for \n and \t to mod_log_config, can be used to produce
4341 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4343 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4345 *) Added informative error messages for failed munmap() and fseek() calls
4346 in http_core.c. [John Bley, Roy Fielding]
4348 *) Added some informative error messages for some failed malloc()
4349 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4351 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4352 is removed. This allows <Directory proxy:*> directives to work and
4353 prevents invalid requests from killing the process.
4354 [Brian Havard <brianh@kheldar.apana.org.au>]
4356 *) Reorganised FAQ document.
4357 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497

4360 David N. Welton: you can now have it generate an HTML TABLE, presumably
4361 for integration into other HTML sources. David updated the ab man page
4362 as well and added some missing descriptions. Thanks!
4363 [David N. Welton <davidw@prosa.it>]

4366 characters in the range 0x80 to 0xff (for example accented characters).
4367 [Paul Sutton] PR#3890
4369 *) Added conditional logging based upon environment variables to
4370 mod_log_config. mod_log_referer and mod_log_agent
4371 are now deprecated. [Ken Coar]
4373 *) Allow apache acting as a proxy server to relay the real
4374 reason of a failure to a client rather than the "internal
4375 server error" it does currently. The general exposure mechanism
4376 can be triggered by any module by setting the "verbose-error-to"
4377 note to "*"; this allows more than just proxy errors to be exposed.
4378 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4380 *) Moved man pages for ab and apachectrl to section 8.
4381 [Wilfredo Sanchez, Roy Fielding]
4383 *) Added -S option to install.sh so that options can be passed to
4384 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4386 *) Tweak modules Makefile generated by Configure so that it handles
4387 the test case of no modules being selected. [chaz@reliant.com]
4389 *) Added a <LimitExcept method ...> sectioning directive that allows
4390 the user to assign authentication control to any HTTP method that
4391 is *not* given in the argument list; i.e., the logical negation
4392 of the <Limit> directive. This is particularly useful for controlling
4393 access on methods unknown to the Apache core, but perhaps known by
4394 some module or CGI script. [Roy Fielding, Tony Finch]
4396 *) Prevent apachectl from complaining if the PIDFILE exists but
4397 does not contain a process id, as might occur if the server is
4398 being rapidly restarted. [Wilfredo Sanchez]
4400 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4402 *) Entity tag comparisons for If-Match and If-None-Match were not being
4403 performed correctly -- weak tags might cause false positives. Also,
4404 strong comparison wasn't properly enforced in all cases.
4405 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657

4410 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4411 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4413 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4414 to util.c for parsing an HTTP header field value to extract the next
4415 list item, taking into account the possible presence of nested comments,
4416 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4417 insignificant whitespace and lowercases non-quoted tokens.
4418 [Roy Fielding] PR#2065
4420 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4421 code different from 500. This allows the proxy to, e.g., return
4422 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4424 *) Fix ordering of language variants for the case where the traditional
4425 negotiation algorithm is being used with multiple language variants
4426 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4428 *) Do not round the TCN quality calculation to 5 decimal places,
4429 unlike RFC 2296, because the calculation might need 12 decimal places
4430 to get the right result. [Roy Fielding]
4432 *) Remove unused code to disable transparent negotiation when
4433 negotiating on encoding only, as we now handle encoding too
4434 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4435 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4436 some debugging statements within mod_negotiation. [Koen Holtman]
4438 *) Fixed a rare memory corruption possibility in mod_dir if the index
4439 file is negotiable and no acceptable variant can be found.
4440 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4442 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4443 searching the Win32 registry for script interpreters.
4446 *) Win32: The compiled-in default filename for the error log is now
4447 error.log, which matches the default in the distributed httpd.conf.
4450 *) Win32: Any error messages from -i or -u command line options are now
4451 displayed on the console output rather than sent to the error log.
4452 Also the "Running Apache..." message is not output unless Apache is
4453 going to serve requests. [Paul Sutton]
4455 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4456 and use a private significator ('$apr1$') to mark passwords as
4457 being smashed with our own algorithm. Also abstract the password
4458 checking into a new ap_validate_password() routine. [Ken Coar]
4460 *) Win32: The filename validity checker now allows "COM" but refuses
4461 access to "COM1" through "COM4". This allows filenames such
4462 as "com.name" to be served. [Paul Sutton] PR#3769.
4464 *) BS2000: Adapt to the new ufork() system call interface which will
4465 make subtasking easier on the OSD/POSIX mainframe environment.
4468 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to

4496 to protect against bare null variable strings (ie: wrapping both
4497 sides with double quotes and prepending 'x'). 'x' was chosen
4498 because it's more universal and hopefully easier for old shell
4499 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4502 *) The status module now prints out both the main server generation as
4503 well as the generation of each process. Also, the vhost info is
4504 printed with '?notable'. [Jim Jagielski]
4506 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4507 and this makes its functions available to things in src/support.
4510 Changes with Apache 1.3.4
4512 *) Renamed macros status_drops_connection to ap_status_drops_connection
4513 and vestigial scan_script_header to ap_scan_script_header_err,
4514 mostly for aesthetic reasons. [Roy Fielding]
4516 *) The query switch "httpd -S" didn't exit after showing the
4517 vhost settings. That was inconsistent with the other query functions.
4520 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4521 filename to the end of the STANDARD_MODULE_STUFF. Its
4522 presence at the beginning prevented reporting of the filename
4523 for modules compiled before 1 January 1999. [Ken Coar]
4525 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4526 to detect and prevent access to special DOS device file names.
4527 [Paul Sutton, Ken Parzygnat]
4529 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4530 and Makefile_win32_debug.txt (debug build) that work on Win95.
4531 Run each of the following from the src directory:
4532 nmake /f Makefile_win32.txt # compiles normal build
4533 nmake /f Makefile_win32.txt install # compiles and installs
4534 nmake /f Makefile_win32.txt clean # removes compiled junk
4535 nmake /f Makefile_win32_debug.txt # compiles debug build
4536 nmake /f Makefile_win32_debug.txt install
4537 nmake /f Makefile_win32_debug.txt clean
4540 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4541 to build binary distributions. [Lars Eilebrecht]
4543 *) IndexOptions SuppressColumnSorting only turned off making
4544 the column headers anchors; you could still change the display
4545 order by manually adding a '?N=A' or similar query string to the
4546 URL. Now SuppressColumnSorting locks in the sort order so
4547 it can't be overridden this way. [Ken Coar]
4549 *) Added IndexOrderDefault directive to supply a default sort order
4550 for FancyIndexed directory listings. [Ken Coar] PR#1699
4552 *) Change the ap_assert macro to a variant that works on all platforms.
4553 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4555 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4556 search for an underscore on dlsym() (as it's already the case
4557 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4559 *) Small fix for mod_env.html: The module was documented as to be _not_
4560 compiled into Apache per default, although it _IS_ compiled into
4561 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4563 *) Instead of fixing a bug in the generation procedure for config.status (a
4564 backslash was missing) we remove the bug together with it's complete
4565 context because the special cases of the past can now no longer occur
4566 because of the recent magic for the --with-layout default.
4567 [Ralf S. Engelschall] PR#3590
4569 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4570 making sure the src/support/ tools are _forced_ to be build last (they
4571 depend on other libraries).
4572 [Markus Theissinger <markus.theissinger@gmx.de>]
4574 *) Fix installation procedure: Now that os-inline.c is actually used (a
4575 recently fixed bug prevented this) we need to also install os-include.c
4576 in addition to os.h into the PREFIX/include/ location or building of
4577 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4579 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4580 allow us to distinguish between a garbled DSO (or even a file which isn't
4581 an Apache module DSO at all) and a DSO which doesn't match the current
4582 Apache API. [Ralf S. Engelschall] PR#3152
4584 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4585 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4586 match case insensitive (this especially avoids nasty patterns like
4587 `[tT][eE][sS][tT]'). Second two additional internal map functions
4588 `escape' and `unescape' were added which can be used to escape/unescape
4589 to/from hex-encodings in URLs parts (this is especially useful in
4590 combination with map lookups).
4591 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4593 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4594 forgotten (because it was a macro) in the symbol renaming process.
4595 [Ralf S. Engelschall]
4597 *) Fix some inconsistencies related to the scopes of directives. The only
4598 user visible change is that the directives `UseCanonicalName' and
4599 `ContentDigest' now use the (more correct) `Options' scope instead of
4600 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4602 *) Using DSO, the Server token was being mangled. Specifically, the
4603 module's token was being added first before the Apache token. This
4604 has been fixed. [Jim Jagielski]
4606 *) Major overhaul of mod_negotiation.c, part 2.
4607 - properly handle "identity" within Accept-Encoding.
4608 - allow encoded variants in RVSA negotiation and let them appear in
4609 the Alternates field using the non-standard "encoding" tag-list.
4610 - fixed both negotiation algorithms so that an explicitly accepted
4611 encoding is preferred over no encoding if "identity" is not
4612 included within Accept-Encoding.
4613 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4614 of large substring sequences.
4615 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4618 *) Major overhaul of mod_negotiation.c, part 1.
4619 - cleanups to mod_negotiation comments and code structure
4620 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4621 support for everything in the upcoming HTTP/1.1
4622 revision (draft-ietf-http-v11-spec-rev-06.txt).
4623 - language tag matching also handles tags with more than 2
4625 - empty Accept, Accept-Language, Accept-Charset headers are
4626 processed correctly; previously an empty header would make all
4627 values acceptable instead of unacceptable.
4628 - allowed for q values in Accept-Encoding
4629 - added support for transparent content negotiation (rfc2295 and
4630 rfc2296) (though we do not implement all features in these drafts,
4631 e.g. no feature negotiation). Removed old experimental version.
4632 - implemented 'structured entity tags' for better cache correctness
4633 (structured entity tags ensure that caches which can deal with Vary
4634 will (eventually) be updated if the set of variants on the server
4636 - this involved adding a vlist_validator element to request_rec
4637 - this involved adding the ap_make_etag() function to the global API
4638 - modified guessing of charsets used by Apache negotiation algorithm
4639 to guess 'no charset' if the variant is not a text/* type
4640 - added code to sort multiviews variants into a canonical order so that
4641 negotiation results are consistent across backup/restores and mirrors
4642 - removed possibility of a type map file resolving to another type map
4643 file as its best variant
4644 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4646 *) RFC2396 allows the syntax http://host:/path (with no port number)
4647 but the proxy disallowed it (ap_proxy_canon_netloc()).
4648 [David Kristol <dmk@bell-labs.com>] PR#3530
4650 *) When modules update/modify the file name in the configfile_t structure,
4651 syntax errors will report the updated name, not the original one.
4652 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
4654 *) Correct some filename case assumptions from WIN32 to
4655 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4657 *) For %v log ServerName regardless of the UseCanonicalName
4658 setting (similarly for %p). [Dean Gaudet]
4660 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4661 rather late (too late for some invocations of TestCompile).
4662 This improves the make environment available to TestCompile and
4663 the *.module scripts. [Martin Kraemer]
4665 *) The hashbang emulation code in ap_execve.c would interpret
4666 #!/hashbang/scripts correctly, but failed to fall back to a
4667 standard shell for scripts which did NOT start with #!
4668 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4670 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4673 *) Update APXS manual page: some -q option arguments were missing
4674 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4676 *) Cleanup the command line options: `-?' was documented to show
4677 the usage list but does it with an error because `?' is not a valid
4678 command. OTOH a lot of users expect `-h' to print such a usage list and
4679 instead are annoyed for ages by our huge unreadable list of directives.
4680 So we now changed the command line options this way:
4682 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4683 very similar to the popular linker option.
4685 Intent: while -l gives the small list of modules, -L now gives the
4686 large list of directives implemented by these modules. This is also
4687 consistent with -v (short version info) and -V (large version info).
4689 Intent: it's now the expected option ;-)
4690 The manual page was adjusted accordingly.
4691 [Ralf S. Engelschall] PR#2714
4693 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4694 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4696 *) Removed recently introduced bugs and disfigurements in APACI:
4697 o fixed argument line processing: using $args was broken: It was not
4698 initialized and using args="$args $apc_option" and even args="$args
4699 \"$apc_option\"" fails in the second processing round for any arguments
4700 containing whitespaces. The only correct way is to use the construct
4701 "$@" (but not possible here) or iterate _both_ times over the implicit
4702 argument line (no argument to for-loop) which is what we now use.
4703 o make --with-layout=Apache the default without creating
4704 redundancy (copying the --with-layout block in the argument parsing
4705 loop). We achieve this by using the "$@" construct together with the
4706 `set' command to prepend --with-layout=Apache to the command line in
4707 case --with-layout is not used.
4708 o fixed auto-suffix handling now that config.layout exists.
4709 Paths which are auto-suffixed are marked with a trailing plus sign in
4710 config.layout and every path now can be marked this way (not only the
4711 four paths for which we do it currently). Additionally the suffix is
4712 no longer a static one. Instead it's now `/<target>' where <target> is
4713 the argument of the --target option or per default `httpd'.
4714 o allow also tabs (and only spaces) where we match whitespaces
4715 o various fixes and cleanups related to used shell coding style
4716 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4717 o trimmed output of --help to fit into 80 columns
4718 [Ralf S. Engelschall]
4720 *) Added two new core API functions, ap_single_module_configure() and
4721 ap_single_module_init(), which are now used by mod_so to configure a module
4722 after loading. [Ralf S. Engelschall]
4724 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4725 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4726 of ap_config.h to allow serialized accept for multiport listens.
4727 [Roy Fielding, Curt Sampson] PR#3120
4729 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4730 of ap_config.h that would skip several defines if DEFAULT_GROUP
4731 was overridden. [Roy Fielding]
4733 *) PORT: The I86 version of DGUX has support for strncasecmp and
4734 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4736 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4737 defined before it might be used. [Victor Khimenko]
4739 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4740 [Tom Serkowski <tks@bsdi.com>] PR#3453
4742 *) Make generation of src/Configuration.apaci more robust: It failed to
4743 differenciate between modules when one module name was a postfix of
4744 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4745 just XXX (think about totally non-standard names like "apache_ssl", too).
4746 [Ralf S. Engelschall] PR#3380
4748 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4749 since 1.3b7) and make whitespace handling more robust (it failed horrible
4750 when whitespaces were present in the arguments of -D options).
4751 [Ralf S. Engelschall] PR#3240
4753 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4754 creates an external package shadow tree in DIR before the local build
4755 shadow tree is generated under DIR. This way one can have the extracted
4756 Apache distribution tree read-only on NFS or CDROM and still build Apache
4757 from these sources. An automatically triggered VPATH-like mechanism is
4758 provided through the TOP variable, too.
4759 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
4761 *) Fix negotiation so that a Vary response header is correctly
4762 generated when, for a particular dimension, variants only vary
4763 in having or not having a value for that dimension. [Paul Sutton]
4765 *) Fix negotiation so that we prefer an encoded variant over an
4766 unencoded variant if the user-agent explicitly says it can
4767 accept that encoding. Previously we always preferred the unencoded
4769 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4771 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4772 and the usage page was inconsistent with the functionality and manpage.
4773 [Ralf S. Engelschall]
4775 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4776 They can occur multiple times and their arguments (`xxx') are passed AS
4777 IS to the compiler/linker command. [Ralf S. Engelschall]
4779 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4780 procedure of mod_rewrite: very long keys were truncated.
4781 [Ralf S. Engelschall]
4783 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4784 identifier, currently "Apache" and "GNU" are pre-defined in the file
4785 config.layout. Custom layouts are possible by using FILE:ID as the
4786 argument where the layout ID is taken from FILE.
4788 The config.layout file consists of <Layout ID>..</Layout> sections
4789 where inside those sections "path_variable: path_value" pairs can be
4790 specified. These lines are converted to path_variable='path_value'.
4792 *) Add a DefaultLanguage directive so that files missing a language
4793 extension (e.g., .fr, .de) can be labelled as being some other
4794 default language. DefaultLanguage can appear in <Directory> and
4795 <Files> containers as well as .htaccess files. [Paul Sutton]
4798 *) Fix TARGET configuration when configuring and installing using
4799 APACI configure. TARGET now defines the basename of the configuration
4800 file, startup script, manual page, etc. log_error_core() now reports
4801 the server binary name given by argv[0]. TARGET can now also be defined
4802 with --target=TARGET parameter passed to APACI configure.
4803 [Ralf Engelschall, Randy Terbush]
4805 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4806 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
4808 *) ap_md5_binary() was using sprintf() rather than a table lookup
4809 to convert binary bytes to hex digits.

4818 when either a handler or a MIME content type is triggered by the request.
4819 [Andrew Pimlott <pimlott@math.harvard.edu>] PR#3340

4825 notice to the error log. It is not possible to send a 401 response
4826 and a redirect at the same time. [Lars Eilebrecht]
4828 *) Fallback to native compilers for IRIX-32 platform. It seems that
4829 a gcc 2.8.1 compiled apache is logging client addresses with all
4830 bits set (255.255.255.255). This is the second such problem caused
4831 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4834 *) Updated mime.types to reflect current Internet media types
4835 and include a URL to the registry.

4842 used to set the document root directory (DOC_ROOT) and the suexec
4843 logfile (LOG_EXEC), respectively. Additionally the --layout option
4844 was changed to show more information about the suEXEC setup.

4909 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4910 in the Configuration[.apaci] file. Two special and important variants are
4911 supported for the option argument: first BEGIN:foo which permutes module
4912 mod_foo with the begin of the module list, i.e. it `moves' the module to
4913 the begin of the list (gives it lowest priority). And second foo:END
4914 which permutes mod_foo with the end of the module list, i.e. it `moves'
4915 the module to the end of the list (gives it highest priority).

4969 *) Remove ap_private_extern method of hiding conflicting symbols
4970 on the NEXT platform because it is not correct for all versions,
4971 and the versions for which it is correct are unknown.
4972 [Wilfredo Sanchez <wsanchez@apple.com>]
4974 *) Fix inheritance of IndexOptions NameWidth and remove unintended
4975 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]
4977 *) Fix per-directory config merging for cases in which a 500 error
4978 is encountered in an .htaccess file somewhere down the tree.
4981 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
4983 *) Fixed a segmentation violation in mod_proxy when a response is
4984 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
4986 Changes with Apache 1.3.3
4988 *) Added a complete implementation of the Expect header field as
4989 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
4990 response when we already know the final status, which is mighty
4991 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4993 *) Remove extra trailing whitespace from the getline results as part
4994 of the protocol processing, which is extra nice because it works
4995 between continuation lines, is almost no cost in the normal case
4996 of no extra whitespace, and saves memory. [Roy Fielding]
4998 *) Added new HTTP status codes and default response bodies from the
4999 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
5000 HTTP Extension Framework (510) specifications. Did not add the
5001 WebDAV 424 and 425 codes because they are bogus. We don't use any
5002 of these codes yet, but they are now available to 3rd-party modules.
5005 *) Fix a possible race condition between timed-out requests and the
5006 ap_bhalfduplex select that might result in an infinite loop on
5007 platforms that do not validate the descriptor. [Roy Fielding]
5009 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
5010 running Apache server [Paul Sutton]
5012 *) Fix mod_autoindex bug where directories got a size of "0k" instead
5013 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]
5016 *) PORT: DRS 6000 machine. [Paul Debleecker <pdebleecker@jetair.be>]
5018 *) Add the server signature text (from the core ServerSignature directive)
5019 to the list of envariables available to scripts, SSI, and the like.
5022 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
5023 [M. Laak <maert@proinv.ee>] PR#3108
5025 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
5026 calculation in mod_status for all systems which don't have POSIX
5027 sysconf() (like UTS 2.1) and not only for the NEXT platform.
5028 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
5030 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
5031 mod_auth_db by using ap_getword_white() (which uses ap_isspace())
5032 instead of ap_getword(..., ' ') (which parses only according to spaces
5033 but not tabs). [James Morris <jmorris@intercode.com.au>,

5060 working directory to fill in some blanks. [Ken Parzygnat
5061 <kparz@raleigh.ibm.com>] PR#3001
5063 *) Correct invalid assumption by ap_sub_req_lookup_file() that all
5064 absolute paths begin with "/" -- because they don't on Win32.
5065 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074

5068 so that ErrorDocument 300 processors can reformat the list
5069 if desired. [Ken Coar] PR#2859
5071 *) Add +/- incremental prefixes to IndexOptions keywords, and
5072 enable merging of multiple IndexOptions directives. [Ken Coar]
5074 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
5075 <steve.cameron@compaq.com>]
5077 *) Reconstructed the loop through multiple htaccess file names so
5078 that missing files are not confused with unreadable files.
5081 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
5082 errno on an error, which leads to one error being mistaken for
5083 another when reading non-existent .htaccess files.
5086 *) OS/2: The new header tests get things right, need to update
5087 ap_config.h. [Brian Havard]
5089 *) The Perl %ENV hash will now be setup by default when using the
5090 mod_include `perl' command [Doug MacEachern]
5092 *) PORT: Add Pyramid DC/OSx support to configuration mechanism.
5093 [Earle Ake <akee@wpdiss1.wpafb.af.mil>]

5098 *) Correct comment in mod_log_config.c about its internals.
5099 [Elf Sternberg <elf@halcyon.com>]
5101 *) Avoid possible line overflow in Configure: Use an awkfile to
5102 handle the creation of modules.c [Jim Jagielski]
5104 Changes with Apache 1.3.2
5106 *) Fix bug in ap_remove_module(), which caused problems for dso's
5107 who were the top_module. [Doug MacEachern]
5109 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
5110 mod_auth_db to both be friendly to users who wants to use this version
5111 and to avoid problems under platforms where only version 2.x is present.
5112 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
5114 *) When using ap_log_rerror(), make the error message available to the
5115 *ERROR_NOTES envariables by default. [Ken Coar]
5117 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
5118 You now must define a BS2000Account name for the server User.
5119 This has fewer security implications than the old approach.
5122 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
5123 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
5124 platform to make the braindead HPUX linker happy. Notice, for the module
5125 DSOs we don't have to use this, because these are loaded manually (and
5126 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
5128 *) Remove 64 thread limit on Win32.
5129 [Bill Stoddard <stoddard@raleigh.ibm.com>]
5131 *) Remove redundant substitutions in top-level Makefile.tmpl.
5132 [Ralf S. Engelschall]
5134 *) Fix APACI's `Group' configuration adjustment - especially for Linux
5135 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
5137 *) Make PrintPath work generically instead of having one version
5138 strictly for OS/2. [Jim Jagielski, Brian Havard]
5140 *) Fix the recently introduced C header file checking: We now use the C
5141 pre-processor pass only (and no longer the complete compiler pass) to
5142 determine whether a C header file exists or not. Because only this way
5143 we're safe against inter-header dependencies (which caused horrible
5144 portability problems). The only drawback is that we now have a CPP
5145 configuration variable which has to be determined first (we do a similar
5146 approach as GNU Autoconf does here). When all fails the user still has
5147 the possibility to override it manually via APACI or src/Configuration.
5148 As a fallback for the header check itself we can directly check the
5149 existance of the file under /usr/include, too.
5150 [Ralf S. Engelschall] PR#2777
5152 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
5153 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
5154 ap_private_extern defined to hide symbols that conflict with loaded
5155 dynamic libraries on the NEXT and RHAPSODY platforms.
5156 [Wilfredo Sanchez <wsanchez@apple.com>]
5158 *) Delete PID file on clean shutdowns.

5170 *) Fix possible buffer overflow situation in suexec.c.
5171 [Jeff Stewart <jws@purdue.edu>] PR#2790
5173 *) Add some more LIBS for the SCO5 platform which are needed for the already
5174 used -lprot. It's actually a bug in SCO5, of course.
5175 [Ronald Record <rr@sco.com>] PR#2533
5177 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
5178 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
5180 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
5181 platform, because it's only supported under version 4.0 and higher. But
5182 because our GuessOS is still unaware of Digital UNIX versions and the
5183 -msym is just to optimize the DSO statup time a little bit it's safe and
5184 best when we leave it out now. [Ralf S. Engelschall] PR#2969
5186 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
5187 functions: First all three functions no longer fail on strings containing
5188 "%" chars and second ap_log_printf() no longer does a double-formatting
5189 (instead it directly passes through the message to be formatted to the
5190 real internal formatting function). [Ralf S. Engelschall] PR#2941
5192 *) Allow "Include" directives anywhere in the server config
5193 files (but not .htaccess files). [Ken Coar] PR#2727
5195 *) The proxy was refusing to serve CONNECT requests except to
5196 port 443 (https://) and 563 (snews://). The new AllowCONNECT
5197 directive allows the configuration of the ports to which a
5198 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5200 *) mod_expires will now act on content that is not sent from a file
5201 on disk. Previously it would never add an Expires: header to
5202 any response that did not come from a file on disk; the only
5203 case where it still doesn't (and can't) add one for that type of
5204 content is if you are using a modification date based setting.
5205 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
5207 *) Problems encountered during .htaccess parsing or CGI execution
5208 that lead to a "500 Server Error" condition now provide explanatory
5209 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
5212 *) Add NameWidth keyword to IndexOptions directive so that the
5213 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
5216 *) Recognize lowercase _and_ uppercase `uname' results under
5217 SCO OpenServer. [David Coelho <drc@ppt.com>]
5219 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5220 a common problem of (mis-administrated?) IIS servers, make the apache
5221 proxy immune to these errors (and ignore the duplicates, but log
5222 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5224 *) The <IfModule and <IfDefine block starting directives now only
5225 allow exactly one argument. Previously, the optional negation
5226 character '!' could be separated by whitespace without a syntax
5227 error being reported, albeit defeating the IfModule functionality
5228 (enclosed directives would ALWAYS be executed). By using the
5229 stricter syntax, these hard-to-track errors can be avoided.
5232 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5233 cause the standalone FancyIndexing directive to logically OR
5234 into any existing IndexOptions settings rather than wiping
5235 them out. [Ken Coar]
5237 *) Changes in ftp proxy: make URL parsing simpler by using the
5239 + Add display of the "current directory" in cases where it's
5240 different from the supplied path (e.g., ftp://user@host/ lives
5241 in /home/user, not in /, therefore clicking on "../" in the
5242 starting directory might send us to /home/).
5243 + When ftp login fails, (esp. when a user name was part of the
5244 URL already), we now return [401 Unauthorized ] to allow the
5245 browser to pop up an authorization dialog. This makes passwords
5246 slightly less visible (they don't appear in the regular log files)
5247 and implements a functionality that other www proxy servers
5251 *) Triggered by the recent "Via:" header changes, the proxy module would
5252 dump core for replies with invalid headers (e.g., duplicate
5253 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5254 core dump is avoided. Also, broken replies are not cached.
5255 [Martin Kraemer] PR#2914
5257 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
5258 plop gmon.out profile data for each child [Doug MacEachern]
5260 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
5261 config.status script to be immune against arguments with whitespaces.
5262 [Yves Arrouye <yves@apple.com>] PR#2866
5264 *) Replace the inlined information grabbing stuff for the configuration
5265 adjustment feature (no --without-confadjust) with calls to a new helper
5266 script `buildinfo.sh' which is both more flexible and already proofed to
5267 be more robust against platform differences. This mainly fixes the
5268 recently occured ``sed: command garbled: ...'' problems.
5269 [Ralf S. Engelschall] PR#2776, PR#2848
5271 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
5272 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
5273 without complains after we recently added the POST feature.
5274 [Ralf S. Engelschall]
5276 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
5277 modules as API functions and we forgot them at the big symbol renaming.
5278 [Ralf S. Engelschall]
5280 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html
5281 [Youichirou Koga <y-koga@jp.FreeBSD.ORG>] PR#2895

5286 *) Add the ability to do POST requests to the ab benchmarking tool.
5287 [Kurt Sussman <kls@best.com>] PR#2871
5289 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5290 5 to 10 because there are some users out there who always have 5 to 8
5291 variables in one RewriteRule and had to patch mod_rewrite.h for every
5292 release. So 15 should be now more than enough, even for them. (I never
5293 needed more than 4 in my RewriteRules ;-)
5294 [Ralf S. Engelschall]
5296 *) Make the proxy generate and understand Via: headers
5299 *) Change the proxy to use tables instead of array_headers for
5300 the header lines. [Martin Kraemer]
5302 *) Make sure the config.status file is not overridden when just
5303 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
5305 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
5306 provide a way to trace API changes that add functionality but do
5307 not create a compatibility issue for precompiled modules, etc.
5308 See include/ap_mmn.h for more details. [Randy Terbush]
5310 *) Fix suexec installation under `make install root=xxx' situation.
5311 [Ralf S. Engelschall]
5313 *) Extend the output of the -V switch to include the paths of all
5314 compiled-in configuration files, if they were overridden at
5315 compile time, for least astonishment of the user.
5318 *) When READing a request in ExtendedStatus mode, the "old"
5319 vhost, request and client information is not displayed.
5322 *) STATUS is no longer available. Full status information now
5323 run-time configurable using the ExtendedStatus directive.
5326 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5327 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5328 a function which can be used to perform bulk update operations
5329 on tables in a more efficient manner. [Dean Gaudet]
5331 *) SECURITY: Added compile-time and configurable limits for
5332 various aspects of reading a client request to avoid some simple
5333 denial of service attacks, including limits on maximum request-line
5334 size (LimitRequestLine), number of header fields (LimitRequestFields),
5335 and size of any one header field (LimitRequestFieldsize). Also added
5336 a configurable directive LimitRequestBody for limiting the size of the
5337 request message body. [Roy Fielding]
5339 *) Make status module aware of DNS and logging states, even if
5340 STATUS not defined. [Jim Jagielski]
5342 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
5344 *) Enhance mod_speling so that CheckSpelling can be used in
5345 <Directory> containers and .htaccess files. [Ken Coar]
5347 *) API: new ap_custom_response() function for hooking into the
5348 ErrorDocument mechanism at runtime [Doug MacEachern]
5350 *) API: new ap_uuencode() function [Doug MacEachern]
5352 *) API: scan_script_header_err_core() now "public" and renamed
5353 ap_scan_script_header_err_core() [Doug MacEachern]
5355 *) The 'status' module will now show the process pid's and their
5356 state even without full STATUS accounting. [Jim Jagielski]
5358 *) Restore the client IP address to the error log messages, this
5359 was lost during the transition from 1.2 to 1.3. Add a new
5360 function ap_log_rerror() which takes a request_rec * and
5361 formats it appropriately. [Dean Gaudet] PR#2661
5363 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5364 whitespace in input lines -- including within quoted strings.
5366 but leading and trailing whitespace should continue to be
5367 stripped [Martin Kraemer]
5369 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5370 the ugly use of an env. variable and use command-line args for
5371 alternate $PATH. Make more like advanced 'type's as well.
5374 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
5375 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
5376 <alain.st-denis@ec.gc.ca>] PR#2736
5378 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
5380 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
5381 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
5382 directory was renamed to src/os/os2/ for consistency.
5383 [Brian Havard, Ralf S. Engelschall]
5385 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5386 files (here modules) against other DSO files (here shared libraries).
5387 This is done by determining a subset of LIBS which can be safely used for
5388 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5389 disabled for all platforms to avoid problems with this (experimental)
5390 rule. But we provide it now for those people how ran into problems and
5391 want to came out by forcing linking against DSOs.
5392 [Ralf S. Engelschall] PR#2587
5394 *) Fix suEXEC start message: Has to be of `notice' level to really get

5410 *) One more portability fix for APACI shadow tree support: Swap order of awk
5411 and sed in top-level configure script to avoid sed fails on some

5471 malformed header fields (400). [Roy Fielding] PR#2646
5473 *) Add support for the Max-Forwards: header line required by RFC2068 for
5474 the TRACE method. This allows apache to TRACE along a chain of proxies
5475 up to a predetermined depth. [Martin Kraemer]
5477 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
5478 (compilers complained) and the .so.V.R.P filename extension was adjusted
5479 to correctly reflect the 1.3.2 version.

5509 the scheme://sitepart string only, or to omit the query string.
5512 *) WIN32: Canonicalize ServerRoot before checking to see if it
5513 is a valid directory. The failure to do this caused certain
5514 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
5515 rejected. [Marc Slemko]
5517 *) Global renaming of C header files to both get rid of conflicts with third
5518 party packages and to again reach consistency:
5519 1. conf.h -> ap_config.h
5520 2. conf_auto.h -> ap_config_auto.h \ these are now merged
5521 3. ap_config.h -> ap_config_auto.h / in the config process

5524 Backward compatibility files for conf.h and compat.h were created.
5526 *) mod_mmap_static will no longer take action on requests unless at
5527 least one "mmapfile" directive is present in the configuration.
5528 This experimental module has to do some black magic to operate
5529 inside the current API and thus creates side-effects for other
5530 modules under some circumstances.

5640 which of three dozen different versions of "ps" are installed.
5643 *) WIN32: If we can't figure out how to execute a file in a script
5644 directory, bail out of the request with an error message. [W G Stoddard]
5646 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
5647 these are treated by Win32 as if they are ".." but are not detected by
5648 other machinery within Apache. This is something of a kludge but
5649 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5651 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5652 pools and thus pollutes libap (until the pool stuff is moved there).

5666 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5667 remove some of the classical hurdles for new users when setting up
5668 Apache. This is done per default because it is useful for the average
5669 user. Package authors can use the --without-confadjust option to disable
5670 these configuration adjustments.
5671 [Ralf S. Engelschall]
5673 *) Added an EXTRA_DEPS configuration parameter which can be used
5674 to add an extra Makefile dependency for the httpd target, for instance
5675 to external third-party libraries, etc.

5678 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5679 as <IfModule>..</IfModule> sections) which can be used to skip or process
5680 contained commands dependend of ``-D PARAMETER'' options on the command
5681 line. This can be used to achieve logical conditions like <IfDefine
5682 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5683 and thus especially can be used for conditionally loading DSO-based
5684 modules via LoadModule, etc. [Ralf S. Engelschall]

5690 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
5691 truncated which forced following HTTP headers to be data in the HTTP
5692 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5695 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5696 in top-level configure script to avoid sed fails on some platforms (for
5697 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5698 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5700 *) Improve performance of directory listings (mod_autoindex) by comparing
5701 integer keys (last-modified and size) as integers rather than converting
5702 them to strings first. Also use a set of explicit byte tests rather
5703 than strcmp() to check for parent directory-ness of an entry. Oh, and
5704 make sure the parent directory (if displayed) is *always* listed first
5705 regardless of the sort key. Overall performance winnage should be good
5706 in CPU time, instruction cache, and memory usage, particularly for large
5707 directories. [Ken Coar]
5709 *) Add a tiny but useful goody to APACI's configure script: The generation
5710 of a config.status script (as GNU Autoconf does) which remembers the used
5711 configure command and hence can be used to restore the configuration by
5712 just re-running this script or for remembering the configuration between
5714 [Ralf S. Engelschall]
5716 *) Add httpd -t (test) option for running configuration syntax tests only.
5717 If something is broken it complains and exits with a return code
5718 non-equal to 0. This can be used manually by the user to check the Apache
5719 configuration after editing and is also automatically used by apachectl
5720 on (graceful) restart command to make sure Apache doesn't die on restarts
5721 because of a configuration which is now broken since the last (re)start.
5722 This way `apachectl restart' can be used inside cronjobs without having
5723 to expect Apache to be falling down. Additionally the httpd -t can be run
5724 via `apachectl configtest'.

5874 generated Makefile more user friendly. [Ralf S. Engelschall]
5876 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5877 was updated to use the normal apache error processing, thereby allowing
5878 proxy errors to be treated by ErrorDocument's as well. For this
5879 purpose, a new module-to-core communication variable "error-notes"
5880 was introduced; the proxy (and possibly other modules) communicates
5881 its error text using this variable. Its content is copied to a new
5882 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5883 The old proxy special error routine ap_proxy_log_uerror()

5968 variable is not the truth. Instead a special variable named LD_SHLIB is
5969 reasonable because although "ld" is usually the default, the command for
5970 building DSO files can be "libtool" or even "cc" on some systems.
5971 [Ralf S. Engelschall]
5973 *) Replace the AddVersionPlatform directive with ServerTokens which
5974 provides for more control over the format of the Server:
5975 header line. SERVER_SUBVERSION is no longer supported;
5976 all module should use the ap_add_version_component()
5977 API function instead. [Jim Jagielski]
5979 *) Support for the NCR MP/RAS 3.0
5980 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5982 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5983 not retrieved in src/Configure and thus was not useable.
5984 [Ralf S. Engelschall]
5986 *) Various Makefile consistency cleanups:
5987 - make OSDIR also automatically be relative to src/ like INCDIR
5988 - SUBDIRS is now generated in src/Makefile only and not in
5989 Makefile.config because it is a local define for this location.
5990 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5991 any Makefile but make sure that at least the "-K inline" is kept in
5993 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5994 - updated the dependencies theirself
5995 - removed not existing SHLIB variable from "clean" targets
5996 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5997 already exists and OBJS_PIC are also just plain objects and have not
5998 directly to do with "shared" things. The only difference is that they
5999 contain PIC. So OBJS_PIC is the more canonical name.
6000 - Updated the Makefile-dependency lines for OBJS_PIC
6001 - Removed the Makefile-dependency line in Configure to avoid double
6003 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
6004 of xxx.lo as GNU libtool does with its PIC objects
6005 - reduce local complexity in modules Makefile.tmpl by moving the last
6006 existing target "depend" to the generation section in Configure, too.
6007 - removed the historical $(SPACER) which was used in the past together
6008 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
6009 is no longer needed.
6010 - force the build and run of the gen_xxx programs under main/ as the
6011 first step before building the objects because it looks cleaner
6012 [Ralf S. Engelschall]
6014 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
6017 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
6020 *) WIN32: Don't force ISAPI headers to finish with \n.
6021 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
6023 *) When opening "configuration" files (like httpd.conf, htaccess
6024 and htpasswd), Apache will not allow them to be non-/dev/null
6025 device files. This closes a DoS hole. At the same time,
6026 we use ap_pfopen to open these files to handle timeouts.
6027 [Jim Jagielski, Martin Kraemer]
6029 *) Apache will now log the reason its httpd children exit if they exit
6030 due to an unexpected signal. (It requires a new porting define,
6031 SYS_SIGLIST, which if defined should point to a list of text
6032 descriptions of the signals available. See PORTING.) [Dean Gaudet]
6034 *) WIN32: chdir() doesn't make sense in a multithreaded environment
6035 like WIN32. Before, Win32 CGI's could have had sporadic failures
6036 if a chdir call from one thread was made between another chdir call
6037 and a spawn in another thread. So, for now don't chdir for CGI scripts
6038 in WIN32. The current CGI "spec" is unclear as to whether it's
6039 necessary. Long-term fix is to either serialize the chdir/spawn combo
6040 or use WIN32 native calls to spawn a process. This temp fix was
6041 necessary to remove this as a showstopper for 1.3's release.
6044 *) Cleanup the suEXEC support in APACI and make it more safe:
6045 1. Add big fat hint in INSTALL about risks and to read the
6046 htdocs/manual/suexec.html document before using the suexec-related
6048 2. Make sure the user has at least provided one --suexec-xxxx option
6049 (specifies suEXEC parameters) in addition to --enable-suexec option.
6050 If only --enable-suexec is given APACI stops with a hint to INSTALL
6051 and htdocs/manual/suexec.html documents.
6052 3. Provide two additional --suexec-xxxx options to make the suEXEC
6053 configuration complete (especially for package maintainers who else
6054 had to patch the source tree) by providing ways to configure minimal
6055 UID/GID and safe PATH, too.
6056 [Ralf S. Engelschall]
6058 *) Cleanup of the `configure --shadow' process:
6059 - make sure the configure script creates its temporary files in the
6060 shadow tree to avoid conflicts with parallel configure runs
6061 - removed unnecessary option "-r" from "rm" call for Makefiles
6062 - make sure the configure scripts creates the shadow-wrapper Makefile
6063 only when no shadow trees already exists
6064 - make sure "make distclean" removes the shadow-wrapper Makefile but only
6065 when no more shadow trees exists
6066 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
6067 as fast (in the past it needed 70sec, now it runs just 38sec)
6068 - make sure CVS does not complain about the created files
6069 Makefille.<gnutriple> and directories src.<gnutriple>
6070 [Ralf S. Engelschall]
6072 *) Added the ap_add_version_component() API routine and the
6073 AddVersionPlatform core directive. The first allows modules to
6074 declare themselves in the Server response header field value,
6075 augmenting the SERVER_SUBVERSION define in the Configuration file
6076 with run-time settings (more useful in a loadable-module environment).
6077 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
6078 into the server version string. [Ken Coar] PR#2056
6080 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
6083 *) Emit the "Accept-Range" header for the default handler.
6084 [Brian Behlendorf] PR#1464
6086 *) Add a note to httpd.conf-dist that apache will on some systems fail
6087 to start when the Group # is set to a negative or large positive value.
6090 *) Make sure the module execution order is correct even when some modules
6091 are loaded under runtime (`LoadModule') via the DSO mechanism:
6092 1. The list of loaded modules is now a dynamically allocated one
6093 and not the original statically list from modules.c
6094 2. The loaded modules are now correctly setup by LoadModule for
6095 later use by the AddModule command.
6096 3. When the DSO mechanism for modules is used APACI's `install'
6097 target now enables all created `LoadModule' lines per default because
6098 this is both already expected by the user _and_ needed to avoid
6099 confusion with the next point and reduces the Makefile.tmpl complexity
6100 4. When the DSO mechanism for modules is used, APACI's `install'
6101 target now additionally makes sure the module list is reconstructed
6102 via a complete `ClearModuleList+AddModule...' entry.
6103 5. The support tool `apxs' now also makes sure an AddModule command
6104 is added in addition to the LoadModule command.
6105 6. The modules.c generation was extended to now contain two
6106 comments to make sure no one is confused by the confusing terminology
6107 of loading/linking (we use load=link+load & link=activate instead of
6108 the obvious load=activate & link=link :-( )
6109 This way now there is no longer a difference under execution time between
6110 statically and dynamically linked modules.
6111 [Ralf S. Engelschall]
6113 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
6114 Big Symbol Renaming. [Ralf S. Engelschall]
6116 *) Add a comment to mod_example.c showing the format of a FLAG command
6119 *) Standardized the time format in mod_status to match that of other
6120 places in the code (e.g. DATE_GMT). PR#1551
6122 *) Fix handling of %Z in timefmt strings for those platforms with no time
6123 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
6126 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
6127 feature compatible with 'UseCanonicalName off' by changing
6128 r->server->server_hostname to ap_get_server_name(). And I changed some
6129 functions which use r->server->port to use ap_get_server_port() instead,
6130 because if there's no Port directive in the config r->server->port is 0.
6133 *) get/set_module_config are trivial enough to be better off inline. Worth
6134 1.5% performance boost. [Dean Gaudet]
6136 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
6137 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
6140 *) [BS2000 security] BS2000 needs an extra authentication to initialize
6141 the task environment to the unprivileged User id. Otherwise CGI scripts
6142 would have a way to gain super user access. [Martin Kraemer]
6144 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
6145 absolute path, only log base name of logging source as is done
6146 in unix. [Martin Kraemer]
6148 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6149 the encoding type from the Accept-Encoding header (if it's there)
6150 and use it in the response, as that's probably what it'll be expecting.
6151 [Ronald.Tschalaer@psi.ch]
6153 *) Fix to mod_alias: translate_alias_redir is dealing with
6154 a URI, not a filename, so the check for drive letters for win32
6155 and emx is not necessary. [Dean Gaudet]
6157 *) WIN32: Allow .cmd as an executable extension.
6158 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
6160 *) Make Apache header files, and some variables, C++ friendly.
6161 [Michael Anderson's <mka@redes.int.com.mx>]
6163 *) Child processes can now "signal" (by exiting with a status
6164 of APEXIT_CHILDFATAL) the parent process to abort and
6165 shutdown the server if the error in the child process was
6166 fatal enough. [Jim Jagielski]
6168 *) mod_autoindex's find_itme() was sensitive to MIME type case.
6169 [Jim Jagielski] PR#2112
6171 *) Make sure the referer_log and agent_log entries in the default httpd.conf
6172 file are also adjusted for the actual relative installation paths.
6173 [Ralf S. Engelschall] PR#2175
6175 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
6177 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
6180 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6181 Additionally the checks for finding the vendor DSO library were moved
6182 from mod_so.c to Configure because first it needs $PLAT etc. and second
6183 mod_so already uses an abstraction layer and does not fiddle with the
6184 vendor functions itself.
6185 [Jens-Uwe Mager, Ralf S. Engelschall]
6187 *) PORT: Some optimization defines for NetBSD
6188 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6190 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6191 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6193 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6194 AIX variants should work fine, too. Even AIX 3.x should work). This is
6195 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6196 which we put into a os/unix/os-dso-aix.c file.
6197 [Ralf S. Engelschall]
6199 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6200 that we should use NET_SIZE_T == int but the include files force size_t.
6201 [Ralf S. Engelschall]
6203 *) Fix two bugs in select() handling in http_main.c.
6206 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6207 is unset (as it is in situations like timeouts) where it is unclear
6208 whether errno is set or not. [Martin Kraemer]
6210 *) Just having APACI's localstatedir is too general and not enough for most
6211 of the systems. 1.3b6 again required manual APACI patches by package
6212 maintainers from RedHat and FreeBSD because for their filesystem layout a
6213 little bit more flexibility in configuring the paths is needed. Hence we
6214 provide three additional configure options (--runtimedir, --logfiledir,
6215 --proxycachedir) which now can be used for more granular adjustments if
6216 --localstatedir is not enough to fit the particular needs. As a nice
6217 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6218 [Ralf S. Engelschall]
6220 *) Make the install root for "make install" in APACI's Makefile overrideable
6221 by package authors. This way we are even more friendly to package
6222 maintainers (especially Debian and RedHat) who build for the real prefix
6223 via "configure --prefix=/<real>" but use a different local prefix via
6224 "make root=/tmp/apache install" for rolling the package without bristling
6225 the target location on their system.
6226 [Ralf S. Engelschall]
6228 *) Workaround sed limitations in APACI's configure script by now
6229 substituting in chunks of 50 commands (because for instance HPUX's vendor
6230 sed has a limit of max. 98 commands)
6231 [Ralf S. Engelschall] PR#2136
6233 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
6234 [Ralf S. Engelschall] PR#2140
6236 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6237 RENAMING process because they are defined as pre-processor macros instead
6238 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6239 [Ralf S. Engelschall]
6241 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6242 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6243 [Ralf S. Engelschall] PR#2139
6245 *) Various bugfixes and cleanups for the APACI configure script:
6246 o fix IFS handling for _nested_ situation
6247 o fix Perl interpreter search: take first one found instead of last one
6248 o fix DSO consistency check
6249 o print error messages to stderr instead of stdout
6250 o add install-quiet for --shadow situation to Makefile stub
6251 o reduce complexity by avoiding sed-hacks for rule and module list loops
6252 [Ralf S. Engelschall]
6254 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6256 *) Make sure the input field separator (IFS) shell variable is explicitly
6257 initialized correctly before _every_ `for' loop and also restored after
6258 the loops. [Ralf S. Engelschall]
6260 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6261 `magic' files from an existing Apache installation. Because people often
6262 customize these for own MIME and content types.
6263 [Ralf S. Engelschall]
6265 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
6266 [Peter Galbavy, Ralf S. Engelschall] PR#2109
6268 *) Fix the path to the ScoreBoardFile in the install-config target, too.
6269 [Ralf S. Engelschall] PR#2105
6271 *) Let "configure" clear out the users parameters (provided as shell
6272 variables) to avoid side-effects in "src/Configure" when the user
6273 exported them (which is not needed, but some users do it).
6274 [Ralf S. Engelschall] PR#2101
6276 *) Provide backward compatibility from some old src/Configuration.tmpl
6277 parameter names to the canonical Autoconf-style shell variable names. For
6278 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
6279 but a hint message is displayed. [Ralf S. Engelschall]
6281 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
6282 CGI scripts from an existing Apache installation.
6283 [Ralf S. Engelschall, Jim Jagielski] PR#2084
6285 *) Make `configure --compat' more "compatible" by first
6286 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
6287 second by making sure the "avoid-bristling-suffix" /apache is not
6288 appended to sysconfdir, datadir, localstatedir and includedir when
6289 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
6291 *) NeXT required strdup() in support/logresolve.c

6297 *) Fix the path to the MimeMagicFile in the install-config target, too.
6298 [Ralf S. Engelschall] PR#2089
6300 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6302 *) If you start apache with the -S command line option it will dump
6303 out the parsed vhost settings. This is useful for folks trying
6304 to figure out what is wrong with their vhost configuration.
6305 (Other dumps may be added in the future.) [Dean Gaudet]
6307 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6308 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6311 *) Because /usr/local/apache is the default prefix the ``configure
6312 --compat'' option no longer has to set prefix, again. This way the
6313 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6315 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6316 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6317 to avoid "discard const" warnings. [Ralf S. Engelschall]
6319 *) If a specific handler is set for a file yet the request still
6320 ends up being handled by the default handler, log an error
6321 message before handling it. This catches things such as trying
6322 to use SSIs without mod_include enabled. [Marc Slemko]
6324 *) Fix error logging for the startup case where ap_log_error() still uses
6325 stderr as the target. Now the default log level is honored here, too.
6326 [Ralf S. Engelschall]
6328 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
6329 long" errors when generating the MODULES entry for src/Makefile
6330 [Ben Hyde, Ralf S. Engelschall]
6332 *) Make sure src/Configure doesn't complain about the old directory
6333 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6335 Changes with Apache 1.3b6
6337 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6339 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6340 interface via the similar but proprietary HP/UX shl_xxx-style system
6341 calls. [Ralf S. Engelschall]
6343 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6344 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6345 Make. [Ralf S. Engelschall]
6347 *) ++++ THE BIG SYMBOL RENAMING ++++
6348 To avoid symbol clashes with third-party code compiled into the server,
6349 we globally applied the prefix "ap_" to the following classes of
6351 - Apache provided general functions (e.g., ap_cpystrn)
6352 - Public API functions (e.g., palloc, bgets)
6353 - Private functions which we can't make static (because of
6354 cross-object usage) but should be (e.g., new_connection)
6355 For backward source compatibility a new header file named compat.h was
6356 created which provides defines for the old symbol names and can be used
6357 by third-party module authors.
6360 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6361 problem under SVR4 is that there is no command flag to force the linker
6362 to export the global symbols of the httpd executable therewith they are
6363 available to the DSO's. Instead of problematic hacks like creating a
6364 dummy.so file (containing dummy references to all global symbols) the
6365 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6366 Placing the Apache core code itself into a DSO library named libhttpd.so.
6367 This way the global symbols _HAVE_ to be exported and thus are available
6368 to any manually loaded DSO's under runtime. To reduce the impact to the
6369 user to null we go even further and create a stub httpd executable which
6370 automatically keeps track of the DSO library loading itself and thus
6371 hides the complete mechanism from the user. Although the generation of
6372 this DSO library is automatically triggered for platforms which
6373 essentially need it (mostly all SVR4-derivates) it can be also enabled
6374 manually via the Rule SHARED_CORE. This can be interesting in the future
6375 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6376 features like graceful upgrades, or whatever.
6377 [Ralf S. Engelschall, Martin Kraemer]
6379 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6381 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6382 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6383 conventions while "clean" removes only stuff created by "all" targets,
6384 "distclean" additionally removes the stuff from the configuration
6385 process. This way "make distclean" (hence the name) provides a fresh
6386 source tree as it was for distribution.
6387 [Ralf S. Engelschall]
6389 *) Allow top-level (APACI) Makefile to break on build errors
6390 the same way the src/ subtree Makefiles breaks on them by replacing the
6391 initial APACI sed-subdir-display-kludge with a more clean
6392 variable-passing-solution: variable SDP can optionally hold the subdir
6393 prefix which is consistently used for displaying the subdir movement.
6394 This way even the top-level Makefile can stop correctly on errors as the
6395 user expects. [Ralf S. Engelschall]
6397 *) Fixed ordering of argument checks for RewriteBase directive.
6398 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6400 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6401 indicating that a module is being compiled for dynamic loading. Also
6402 remove #define IS_MODULE from modules and add SHARED_MODULE define
6403 to the mak/dsp files. [Alexei Kosut]
6405 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6406 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6408 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6410 *) Add documentation file and src/Configuration.tmpl entry for the
6411 experimental mod_mmap_static module. Because although it is and marked as
6412 an experimental one it is distributed and thus should be documented and
6413 prepared for configuration the same way as all others modules.
6414 [Ralf S. Engelschall]
6416 *) Add query (-q) option to apxs support tool to be able to manually query
6417 specific settings from apxs. This is needed for instance when you
6418 manually want to access Apache's header files and you need to assemble
6419 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6420 [Ralf S. Engelschall]
6422 *) Now src/Configure uses a fallback strategy for the shared object support
6423 on platforms where no explicit information is available: If a Perl
6424 installation exists we ask it about its shared object support and if it's
6425 the dlopen-style one we shamelessly guess the compiler and linker flags
6426 for creating shared objects from Perls knowledge. Of course, the user is
6427 warning about what we are doing and informed that he should send us
6428 the guessed flags when they work. [Ralf S. Engelschall]
6430 *) Provide APACI --without-support option to be able to disable the build
6431 and installation of the support tools from the src/support/ area.
6432 Although its useful to have these installed per default we should provide
6433 a way to compile and install without them for backward-compatibility.
6434 [Ralf S. Engelschall]
6436 *) Add of the new APache eXtenSion (apxs) support tool for building and
6437 installing modules into an _already installed_ Apache package through the
6438 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6439 this approach actually doesn't need the Apache source tree. The
6440 (APACI-installed) server package is enough, because this now includes the
6441 Apache C header files (PREFIX/include) and the new APXS tool
6442 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6443 module authors to build their Apache modules _OUTSIDE_ the Apache source
6444 tree while avoiding them to fiddle around with the totally platform
6445 dependend way of compiling DSO files. The tool supports all ranges of
6446 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6447 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6448 on-the-fly generate a minimalistic Makefile and sample module for the
6449 first step to provide both a quick success event and to demonstrate the
6450 APXS mechanism to module authors. [Ralf S. Engelschall]
6452 *) Fix core dumps in use of CONNECT in proxy.
6453 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6455 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6456 so that users have examples of how CustomLog can be used.
6459 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6460 the Apache distribution tree. Until Apache 1.3 there was no real
6461 out-of-the-box batch-capable build and installation procedure for the
6462 complete Apache package. This is now provided by a top-level "configure"
6463 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6464 to provide a GNU Autoconf-style frontend which is capable to both drive
6465 the old src/Configure stuff in batch and additionally installs the
6466 package with a GNU-conforming directory layout. Any options from the old
6467 configuration scheme are available plus a lot of new options for flexibly
6468 customizing Apache. [Ralf S. Engelschall]
6470 *) The floating point ap_snprintf code wasn't threadsafe.
6471 Had to remove the HAVE_CVT macro in order to do threadsafe
6472 calling of the ?cvt() floating point routines. [Dean Gaudet]
6474 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6476 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler

6479 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6480 Configure knows which CC we are using. [Jim Jagielski]
6482 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6483 was defined in a parent directory. [Lars Eilebrecht]
6485 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6486 a generic printf-style routine that can call arbitrary output
6487 routines. Use this to replace http_bprintf.c. Add new routines
6488 psprintf(), pvsprintf() which allocate the exact amount of memory
6489 required for a string from a pool. Use psprintf() to clean up
6490 various bits of code which used ap_snprintf()/pstrdup().
6493 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6494 ap_snprintf() has different semantics and formatting codes than
6495 snprintf(). [Dean Gaudet]
6497 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6498 is necessary on at least Solaris where the /etc/rc?.d scripts
6499 are run with these signals ignored, and "SIG_IGN" settings are
6500 maintained across exec().

6525 properly marked for closure on fork().
6526 [Jürgen Keil <jk@tools.de>] PR#2000
6528 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6529 therefore not exposed to %2F -> '/' translations and 2) the request
6530 is a proxy request, so we're not dealing with a local resource anyway.
6531 Without this, the proxy would fail to work for any URL's with
6532 %2f in them (occurs quite often in
6533 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6535 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6537 *) Make the shared object compilation command more portable by avoiding
6538 the direct combination of `-c' & `-o' which is not honored by some
6539 compilers like UnixWare's cc. [Ralf S. Engelschall]
6541 *) WIN32: the proxy was creating filenames missing the last four
6542 characters. While this normally doesn't stop anything from
6543 working, it can result in extra collisions.

6546 *) Now mod_proxy uses the response string (in addition to the response status
6547 code) from the already used FTP SIZE command to setup the Content-Length
6548 header if available. [Ralf S. Engelschall] PR#1183
6550 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6551 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6552 name was really too generic, added documentation for this directive to
6553 the mod_proxy.html and corrected the hyperlink to it in the
6554 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
6556 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6557 faster [Martin Kraemer]
6559 *) Make Configure die when you give it an unknown command switch.
6562 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6563 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6564 and per default compiled support programs have manual pages - just to
6565 document our stuff a little bit more and to be able to do really
6566 Unix-like installations ;-) [Ralf S. Engelschall]
6568 *) Major cleanups to the Configure script to make it and its generated
6569 Makefiles again readable and maintainable: add SRCDIR option, removed
6570 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6571 generated sections, consequently added Makefile headers with inheritance
6572 information, added subdir movement messages for easier following where
6573 the build process currently stays (more verbose then standard Make, less
6574 verbose than GNU make), same style to comments in the Configure script,
6575 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6577 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6578 from the ZeusBench benchmarking program and can be used to determine the
6579 response performance of an Apache installation. This version is
6580 officially licensed with Zeus Technology, Ltd. See the license agreement
6581 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
6582 [Ralf S. Engelschall]
6584 *) API: Various core functions that are definately not part of the API
6585 have been made static, and a few have been marked API_EXPORT. Still
6586 more have been marked CORE_EXPORT and are not intended for general
6587 use by modules. [Doug MacEachern, Dean Gaudet]
6589 *) mod_proxy was not clearing the Proxy-Connection header from
6590 requests; now it does. This did not violate any spec, however
6591 causes poor interactions when you are talking to remote proxies.
6592 [Marc Slemko] PR#1741
6594 *) Various cleanups to the command line interface and manual pages.
6595 [Ralf S. Engelschall]
6597 *) cfg_getline() was not properly handling lines that did not end
6598 with a line termination character. [Marc Slemko] PR#1869, 1909
6600 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6602 *) Clean up some undocumented behavior of mod_setenvif related to
6603 "merging" two SetEnvIf directives when they match the same header
6604 and regex. Document that mod_setenvif will perform comparisons in
6605 the order they appear in the config file. Optimize mod_setenvif by
6606 doing more work at config time rather than at runtime.
6609 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6610 to allow for modules to overrule them and to reduce redefinition
6611 warnings [Jim Jagielski]
6613 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6616 *) Making the hard-coded cross-module function call mime_find_ct() (from
6617 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6618 checking is really called even for proxy requests except for URLs with
6619 HTTP schemes (because there we can optimize by not running the type
6620 checking hooks due to the fact that the proxy gets the MIME Content-type
6621 from the remote host later). This change cleans up mod_mime by removing
6622 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6623 especially unbundles mod_proxy and mod_mime. This way they both now can
6624 be compiled as shared objects and are no longer tied together.
6625 [Ralf S. Engelschall]
6627 *) util.c cleanup and speedup. [Dean Gaudet]
6629 *) API: Clarification, pstrndup() will always copy n bytes of the source
6630 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6632 *) Mark module command_rec and handler_rec structures const so that they
6633 end up in the read-only data section (and are friendlier to systems
6634 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6636 *) Add check to the "Port" directive to make sure the specified
6637 port is in the appropriate range. [Ben Hyde]
6639 *) Performance improvements to invoke_handler().
6640 [Dmitry Khrustalev <dima@bog.msu.su>]
6642 *) Added support for building shared objects even for library-style modules
6643 (which are built from more than one object file). This now provides the
6644 ability to build mod_proxy as a shared object module. Additionally
6645 modules like mod_example are now also supported for shared object
6646 building because the generated Makefiles now no longer assume there is at
6647 least one statically linked module. [Ralf S. Engelschall]
6649 *) API: Clarify usage of content_type, handler, content_encoding,
6650 content_language and content_languages fields in request_rec. They
6651 must always be lowercased; and the strings pointed to shouldn't
6652 be modified (you must copy them to modify them). Fix a few bugs
6653 related to this. [Dean Gaudet]
6655 *) API: Clarification: except for RAW_ARGS, all command handlers can
6656 treat the char * parameters as permanent, and modifiable. There
6657 is no need to pstrdup() them. Clean up some needless pstrdup().
6660 *) Now mod_so keeps track of which module shared objects with which names
6661 are loaded and thus avoids multiple loading and unloading and irritating
6662 error_log messages. [Ralf S. Engelschall]
6664 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6665 environment variable in the apache core. But that tweaking interferes
6666 with mod_setenv. So don't tweak if the user has specified an explicit
6667 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6669 *) rputs() did not calculate r->sent_bodyct properly.
6670 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6672 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6673 name, or left unset if this value is unavailable. Apache was setting
6674 it to the IP address when unavailable.
6675 [Tony Finch <fanf@demon.net>] PR#1925
6677 *) Various improvements to the configuration and build support for compiling
6678 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6679 OSF1 support with GCC and vendor compilers was added. This way shared
6680 object support is now provided out-of-the-box for FreeBSD, Linux,
6681 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6682 [Ralf S. Engelschall]
6684 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6685 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6686 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6688 *) Fix one more special locking problem for RewriteMap programs in
6689 mod_rewrite: According to the documentation of flock(), "Locks are on
6690 files, not file descriptors. That is, file descriptors duplicated
6691 through dup(2) or fork(2) do not result in multiple instances of a lock,
6692 but rather multiple references to a single lock. If a process holding a
6693 lock on a file forks and the child explicitly unlocks the file, the
6694 parent will lose its lock.". To overcome this we have to make sure the
6695 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6696 the case by opening it in the child_init instead of the module_init API
6697 hook. [Ralf S. Engelschall] PR#1029
6699 *) Change to Location and LocationMatch semantics. LocationMatch no
6700 longer lets a single slash match multiple adjacent slashes in the
6701 URL. This change is for consistency with RewriteRule and
6702 AliasMatch. Multiple slashes have meaning in URLs that they do
6703 not have in (some) filesystems. Location on the other hand can
6704 be considered a shorthand for a more complicated regex, and it
6705 does match multiple slashes with a single slash -- which is
6706 also consistent with the Alias directive.
6707 [Dean Gaudet] related PR#1440
6709 *) Fix bug with mod_mime_magic causing certain files, including files
6710 of length 0, to result in no response from the server.
6713 *) The Configure script now generates src/include/ap_config.h which
6714 contains the set of defines used when Apache is compiled on a platform.
6715 This file can then be included by external modules before including
6716 any Apache header files in case they are being built separately from
6717 Apache. Along with this change, a couple of minor changes were
6718 made to make Apache's #defines coexist peacefully with any autoconf
6719 defines an external module might have. [Rasmus Lerdorf]
6721 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6722 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6723 chance by the API to initialize its per-server configuration and thus
6724 receives the wrong one from the main server. This is now avoided by
6725 remembering the server together with the config structure while
6726 configuring and later assuming there is no config when we see a
6727 difference between the remembered server and the one calling us.
6728 [Ralf S. Engelschall] PR#1790
6730 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6731 is automatically disabled under configure time when the dbm_xxx functions
6732 are not available. Second, two heavy source code errors in the DBM
6733 support code were fixed. This makes DBM RewriteMap's usable again after
6734 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6736 *) Now all configuration files support Unix-style line-continuation via
6737 the trailing backslash ("\") character. This enables us to write down
6738 complex or just very long directives in a more readable way. The
6739 backslash character has to be really the last character before the
6740 newline and it has not been prefixed by another (escaping) backslash.

6746 *) To deal with modules being compiled and [dynamically] linked
6747 at a different time from the core, the SERVER_VERSION and
6748 SERVER_BUILT symbols have been abstracted through the new
6749 API routines apapi_get_server_version() and apapi_get_server_built().
6752 *) WIN32: Preserve trailing slash in canonical path (and hence
6753 in PATH_INFO). [Paul Sutton, Ben Laurie]
6755 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6756 depending on the rev of Solaris and what mixture of modules
6757 are in use. So it has been disabled, and Solaris is back to
6758 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6759 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6760 up static content only servers. Or it may fail unpredictably.
6761 [Dean Gaudet] PR#1779, 1854, 1904
6763 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6766 *) API: Rewrite of absoluteURI handling, and in particular how
6767 absoluteURIs match vhosts. Unless a request is a proxy request, a
6768 "http://host" url is treated as if a similar "Host:" header had been
6769 supplied. This change was made to support future HTTP/1.x protocols
6770 which may require clients to send absoluteURIs for all requests.
6772 In order to achieve this change subtle changes were made to the API. In a
6773 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6774 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6775 by the core, modules must set it during the post_read_request or
6776 translate_names phase.
6778 Plus changes to the virtualhost test suite for absoluteURI testing.
6780 This fixes several bugs with the proxy proxying requests to vhosts
6781 managed by the same httpd.
6784 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6785 code from mod_rewrite. The vhost matching is now performed by a
6786 globally available function matches_request_vhost(). [Dean Gaudet]

6802 *) API: A new source module main/util_uri.c; It contains a routine
6803 parse_uri_components() and friends which breaks a URI into its component
6804 parts. These parts are stored in a uri_components structure called
6805 parsed_uri within each request_rec, and are available to all modules.
6806 Additionally, an unparse routine is supplied which re-assembles the URI
6807 components back to an URI, optionally hiding the username:password@ part
6808 from ftp proxy requests, and other useful routines. Within the structure,
6809 you find on a ready-for-use basis:
6810 scheme; /* scheme ("http"/"ftp"/...) */
6811 hostinfo; /* combined [user[:password]@]host[:port] */
6812 user; /* user name, as in http://user:passwd@host:port/ */
6813 password; /* password, as in http://user:passwd@host:port/ */
6814 hostname; /* hostname from URI (or from Host: header) */
6815 port_str; /* port string (integer representation is in "port") */
6816 path; /* the request path (or "/" if only scheme://host was given) */
6817 query; /* Everything after a '?' in the path, if present */
6818 fragment; /* Trailing "#fragment" string, if present */
6819 This is meant to serve as the platform for *BIG* savings in
6820 code complexity for the proxy module (and maybe the vhost logic).
6823 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6824 ${map:key}) available for all location where a string is created in
6825 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6826 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6827 possible expansions are consequently usable at all string creation
6828 locations. [Ralf S. Engelschall]
6830 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6831 and not 1) and the per-virtual-server merging of directives. Now all
6832 directives except `RewriteEngine' and `RewriteOption' are either
6833 completely overridden (default) or completely inherited (when
6834 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6865 type but with a special post-processing for the looked-up value: It
6866 parses it into alternatives according to `|' chars and then only one
6867 particular alternative is chosen randomly (this is an essential
6868 functionality needed for balancing between backend-servers when using
6869 Apache as a Reverse Proxy. The looked up value here is a list of
6870 servers). Second, `int' with the built-in maps named `tolower' and
6871 `toupper' which can be used to map URL parts to a fixed case (this is an
6872 essential feature to fix the case of server names when doing mass
6873 virtual-hosting with the help of mod_rewrite instead of using
6874 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6875 Jay Soffian <jay@cimedia.com>] PR#1631
6877 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6878 This directive lets Apache adjust the URL in Location-headers on HTTP
6879 redirect responses sent by the remote server. This way the virtually
6880 mapped area is no longer left on redirects and thus by-passed which is
6881 especially essential when running Apache as a reverse proxy.

6931 *) Previously Apache would permit </Files> to end <FilesMatch> (and
6932 similary for Location and Directory), now this is diagnosed as an
6933 error. Improve error messages for mismatched sections (<Files>,
6934 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
6935 [Dean Gaudet, Martin Kraemer]
6937 *) <Files> is not permitted within <Location> (because of the
6938 semantic ordering). [Dean Gaudet] PR#379
6940 *) <Files> with wildcards was broken by the change in wildcard
6941 semantics (* does not match /). To fix this, <Files> now
6942 apply only to the basename of the request filename. This
6943 fixes some other inconsistencies in <Files> semantics

6951 *) Various errors from select() and accept() in child_main() would
6952 result in an infinite loop. It seems these two tickle kernel
6953 or library bugs occasionally, and result in log spammage and
6954 a generally bad scene. Now the child exits immediately,
6955 which seems to be a good workaround.

6982 Changes with Apache 1.3b4
6984 *) The module structure was modified to include a *dynamic_load_handle
6985 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
6986 has been bumped accordingly. [Paul Sutton]
6988 *) All BrowserMatch directives mentioned in
6989 htdocs/manual/known_client_problems.html are in the default
6990 configuration files. [Lars Eilebrecht]
6992 *) MiNT port update. [Jan Paul Schmidt]
6994 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
6995 equivalent, similarly for x-compress and compress. Apache
6996 now ignores a leading x- when comparing encodings. It also
6997 preserves the encoding the client requests (for example if
6998 it requests x-gzip, then Apache will respond with x-gzip
6999 in the Content-Encoding header).

7002 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
7004 *) Added mod_so module to support dynamic loading of modules on Unix
7005 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
7006 instead of AddModule in Configuration to build shared modules

7017 different protocols easier. [Ben Laurie, Randy Terbush]
7019 *) There are many cases where users do not want Apache to form
7020 self-referential urls using the "canonical" ServerName and Port.
7021 The new UseCanonicalName directive (default on), if set to off

7027 PR#315, 459, 485, 1433
7029 *) Yet another rearrangement of the source tree.. now all the common
7030 header files are in the src/include directory. The -Imain -Iap
7031 references in Makefiles have been changed to the simpler -Iinclude
7032 instead. In addition to simplifying the build a little bit, this
7033 also makes it clear when a module is referencing something in a
7034 other than kosher manner (e.g., the proxy including mod_mime.h).
7035 Module-private header files (the proxy, mod_mime, the regex library,
7036 and mod_rewrite) have not been moved to src/include; nor have
7037 the OS-abstraction files. [Ken Coar]
7039 *) Fix a bug where r->hostname didn't have the :port stripped
7040 from it. [Dean Gaudet]
7042 *) Tweaked the headers_out table size, and the subprocess_env
7043 table size guess in rename_original_environment(). Added
7044 MAKE_TABLE_PROFILE which can help discover make_table()
7045 calls that use too small an initial guess, see alloc.c.
7048 *) Options and AllowOverride weren't properly merging in the main
7049 server setting inside vhosts (only an issue when you have no
7050 <Directory> or other section containing an Options that affects
7051 a request). Options +foo or -foo in the main_server wouldn't
7052 affect the main_server's lookup defaults. [Dean Gaudet]
7054 *) Variable 'cwd' was being used pointlessly before being set.
7057 *) r->allowed handling cleaned up in the standard modules.
7060 *) Some case-sensitivity issues cleaned up to be consistent with
7061 RFC2068. [Dean Gaudet]
7063 *) SIGURG doesn't exist everywhere.
7064 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7066 *) mod_unique_id was erroneously generating a second unique id when
7067 an internal redirect occured. Such redirects occur, for example,
7068 when processing a DirectoryIndex match. [Dean Gaudet]
7070 *) API: table_add, table_merge, and table_set include implicit pstrdup()
7071 of the key and value. But in many cases this is not required
7072 because the key/value is a constant, or the value has been built
7073 by pstrcat() or other similar means. New routines table_addn,
7074 table_mergen, and table_setn have been added to the API, these
7075 routines do not pstrdup() their arguments. The core code and
7076 standard modules were changed to take advantage of these routines.
7077 The resulting server is up to 20% faster in some situations.
7079 Note that it is easy to get code subtly wrong if you pass a key/value
7080 which is in a pool other than the pool of the table. The only
7081 safe thing to do is to pass key/values which are in the pool of
7082 the table, or in one of the ancestors of the pool of the table.
7083 i.e. if the table is part of a subrequest, a value from the main
7084 request's pool is OK since the subrequest pool is a sub_pool of the
7085 main request's pool (and therefore has a lifespan at most as long as
7086 the main pool). There is debugging code which can detect improper
7087 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
7088 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
7090 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
7091 which don't exist on disk more gracefully; handles vhosts properly.
7092 Update documentation to reflect the code -- if there's no
7093 MimeMagicFile directive then the module is not enabled.
7096 *) PORT: Some older *nix dialects cannot automatically start scripts
7097 which begin with a #! interpreter line (the shell starts the scripts
7098 appropriately on these platforms). Apache now supports starting of
7099 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
7100 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
7103 *) API: "typedef array_header table" removed from alloc.h, folks should
7104 have been writing to use table as if it were an opaque type, but even
7105 some standard modules got this wrong. By changing the definition
7106 to "typedef struct table table" module authors will receive compile
7107 time warnings that they're doing the wrong thing. This change
7108 facilitates future changes with more sophisticated table
7109 structures. Specifically, module authors should be using table_elts()
7110 to get access to an array_header * for the table. [Dean Gaudet]
7112 *) API: Renamed new_connection() to avoid namespace collision with LDAP
7113 library routines. [Ken Coar, Rasmus Lerdorf]
7115 *) WIN32: mod_speling is now available on the Win32 platform.
7118 *) For clarity the following compile time definition was changed:
7120 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
7122 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
7123 and not be a general notice that the OS has mmap(). Now the
7124 HAVE_MMAP/SHMGET #defines strictly are informational that the
7125 OS has that method of shared memory; the type to use for
7126 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
7127 and USE_SHMGET_SCOREBOARD). This allows outside modules to
7128 determine if shared memory is available and allows Apache
7129 to determine the best method to use for the scoreboard.
7132 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
7133 as do various earlier versions. It should be safe on all versions.

7135 the slack code. A few other cleanups for Unixware.

7144 authenticated. [Roy Fielding] PR#1399

7157 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
7158 The choice of flock vs. fcntl was made based on timings which showed that
7159 even on non-NFS, non-exported filesystems fcntl() was an order of
7160 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7161 that single socket users will see no difference. [Dean Gaudet] PR#467

7187 *) The src/main/*.h header files have had #ifndef wrappers added to
7188 insulate them against duplicate calls if they get included through
7189 multiple paths (e.g., in .c files as well as other .h files).
7192 *) The libap routines now have a header file for their prototypes,
7193 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
7195 *) mod_autoindex with a plaintext header file would emit the <PRE>

7201 only an issue on systems without a MAXDNAME define or where
7202 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]

7218 *) "basic" auth needs a case-insensitive comparison.
7219 [Ronald.Tschalaer@psi.ch] PR#1666
7221 *) For maximum portability, the environment passed to CGIs should
7222 only contain variables whose names match the regex
7223 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
7224 underscores over any character outside the regex. This
7225 affects HTTP_* variables, in a way that should be backward
7226 compatible for all the standard headers; and affects variables
7227 set with SetEnv/BrowserMatch and similar directives.

7266 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7267 including fixing a possible buffer overflow. [Dean Gaudet]
7269 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful

7271 (but there is as yet no way to signal this to Apache). Various
7272 other cleanups. [Paul Sutton]
7274 *) The aplog_error changes specific to 1.3 introduced a buffer
7275 overrun in the (now legacy) log_printf function. Fixed.
7278 *) mod_digest didn't properly deal with proxy authentication. It
7279 also lacked a case-insensitive comparision of the "Digest"

7313 *) send_fd_length() did not calculate total_bytes_sent properly.
7314 [Ben Reser <breser@regnow.com>] PR#1366
7316 *) The bputc() macro was not properly integrated with the chunking
7317 code; in many cases modules using bputc() could cause completely
7318 bogus chunked output. (Typically this will show up as problems
7319 with Internet Explorer 4.0 reading a page, but other browsers
7320 having no problem.) [Dean Gaudet]
7322 *) Create LARGE_WRITE_THRESHOLD define which determines how many
7323 bytes have to be supplied to bwrite() before it will consider
7324 doing a writev() to assemble multiple buffers in one system
7325 call. This is critical for modules such as mod_include,
7326 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
7327 strings in some cases. The result would be extra effort
7328 setting up writev(), and in many cases extra effort building
7329 chunks. The default is 31, it can be overriden at compile

7467 Now the rewriting engine (the heart of mod_rewrite) is organized more
7468 straight-forward, first time well documented and reduced to the really
7469 essential parts. All redundant cases were stripped off and processing now
7470 is the same for both per-server and per-directory context with only a
7471 minimum difference (the prefix stripping in per-dir context). As a
7472 side-effect some subtle restrictions and two recently discovered problems
7473 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
7474 context and restrictions on the substitution URL on redirects.
7475 Additionally some minor source cleanups were done.

7632 *) TestCompile was not passing $LIBS [Dean Gaudet]
7634 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7637 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7638 rudimentary memory debugger which can be used on live servers with
7639 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7640 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7641 and free() for each object. This is far more expensive and should
7642 only be used for testing with tools such as Electric Fence and
7643 Purify. See main/alloc.c for more details. [Dean Gaudet]
7645 *) Configure uses a sh trap and didn't set its exitcode properly.
7646 [Dean Gaudet] PR#1159
7648 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7649 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7650 From a given ip:port, regardless what the Host: header is, you can
7651 only reach the vhosts defined on that ip:port. The precedence of
7652 vhosts was reversed to match other precedences in the config --
7653 the earlier vhosts override the later vhosts. All vhost matching was
7654 moved into http_vhost.[ch]. [Dean Gaudet]
7656 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7657 be used for whatever reason is appropriate (i.e. format() warnings
7658 for printf style functions). Both are enabled only with
7659 gcc >= 2.7.x (so that we have fewer support issues with older
7660 versions). [Dean Gaudet]

7665 *) CoreDumpDirectory directive directs where the core file is

7670 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7672 *) When booting, apache will now detach itself from stdin, stdout,
7673 and stderr. stderr will not be detached until after the config
7674 files have been read so you will be able to see initial error
7675 messages. After that all errors are logged in the error_log.
7676 This makes it more convenient to start apache via rsh, ssh,
7677 or crontabs. [Dean Gaudet] PR#523

7693 *) mod_autoindex improperly counted &escapes; as more than one
7694 character in the description. It also improperly truncated
7695 descriptions that were exactly the maximum length.
7698 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7699 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7702 *) mod_include now uses symbolic names to check for request success
7703 and return HTTP errors, and correctly handles all types of
7704 redirections (previously it only did temporary redirect correctly).
7705 [Ken Coar, Roy Fielding]
7707 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7708 r->filename. Since those two are meant to be in sync with each other

7721 *) Fixed error in proxy_util.c when looping through multiple host IP
7722 addresses. [Lars Eilebrecht] PR#974
7724 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7725 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7726 bytes before writing, but it will never split a log entry across a
7727 buffer boundary. [Dean Gaudet]
7729 *) API: the short_score record has been split into two pieces, one which
7730 the parent writes on, and one which the child writes on. As part of
7731 this change the get_scoreboard_info() function was removed, and
7732 scoreboard_image was exported. This change fixes a race condition
7733 in file based scoreboard systems, and speeds up changes involving the
7734 scoreboard in earlier 1.3 development. [Dean Gaudet]
7736 *) API: New register_other_child() API (see http_main.h) which allows
7737 modules to register children with the parent for maintenance. It
7738 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7740 *) API: New piped_log API (see http_log.h) which implements piped logs,
7741 and will use register_other_child to implement reliable piped logs
7742 when it is available. The reliable piped logs part can be disabled
7743 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7744 logs is only available on Unix. [Dean Gaudet]
7746 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7747 meets_conditions(). This allows conditional HTTP selection to be
7748 handled separately from the storing of the header fields, and provides
7749 the ability for CGIs to set their own ETags for conditional checking.
7750 [Ken Coar, Roy Fielding] PR#895
7752 *) Changes to mod_log_config to allow naming of format strings.
7753 Format nicknames are defined with "LogFormat fmt nickname", and can
7754 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7757 *) New module, "mod_speling", which can help find files even when
7758 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7760 *) API: New function child_terminate() triggers the child process to
7761 exit, while allowing the child finish what it needs to for the
7762 current request first.
7763 [Doug MacEachern, Alexei Kosut]
7765 *) Windows now defaults to using full status reports with mod_status.
7766 [Alexei Kosut] PR #1094
7768 *) *Really* disable all mod_rewrite operations if the engine is off.
7769 Some things (like RewriteMaps) were checked/performed even if they
7770 weren't supposed to be. [Ken Coar] PR #991
7772 *) Implement a new timer scheme which eliminates the need to call alarm() all
7773 the time. Instead a counter in the scoreboard for each child is used to
7774 show when the child has made forward progress. The parent samples this
7775 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7776 progress has been made in the timeout period. This reduces the static
7777 request best-case syscall count to 22 from 29. This scheme is only
7778 used by systems with memory-based scoreboards. [Dean Gaudet]
7780 *) The proxy now properly handles CONNECT requests which are sent
7781 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7783 *) A script called apachectl has been added to the support
7784 directory. This script allows you to do things such as
7785 "apachectl start" and "apachectl restart" from the command
7788 *) Modules and core routines are now put into libraries, which
7789 simplifies the link line tremendously (among other advantages).
7792 *) Some of the MD5 names defined in Apache have been renamed to have
7793 an `ap_' prefix to avoid conflicts with routines supplied by
7794 external libraries. [Ken Coar]
7796 *) Removal of mod_auth_msql.c from the distribution. There are many
7797 other options for databases today. Rather than offer one option,
7798 offer none at this time. mod_auth_msql and other SQL database
7799 authentication modules can be found at the Apache Module Registry.
7800 http://modules.apache.org/ It would be nice to offer a generic
7801 mod_auth_sql option in the near future.
7803 *) PORT: BeOS support added [Alexei Kosut]
7805 *) Configure no longer accepts the -make option, since it creates
7806 Makefile on the fly based on Makefile.tmpl and Configuration.
7808 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7809 of forcibly killing off all its processes and exiting without
7810 cleaning up. [Alexei Kosut]
7812 *) API: A new field in the request_rec, r->mtime, has been added to
7813 avoid gratuitous parsing of date strings. It is intended to hold
7814 the last-modified date of the resource (if applicable). An
7815 update_mtime() routine has also been added to advance it if
7816 appropriate. [Roy Fielding, Ken Coar]
7818 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7819 deny access to the directory with a HTTP_FORBIDDEN. The previous
7820 behavior was to ignore the htaccess file if it could not be read.
7821 This change may make some setups with unreadable htaccess files
7822 stop working. [Marc Slemko] PR#817
7824 *) Add aplog_error() providing a mechanism to define levels of
7825 verbosity to the server error logging. This addition also provides
7826 the ability to log errors using syslogd. Error logging is configurable
7827 on a per-server basis using the LogLevel directive. Conversion
7828 of log_*() in progress. [Randy Terbush]
7830 *) Further enhance aplog_error() to not log filename, line number, and
7831 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7833 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7834 converted to long ones. Backslashes are converted to forward
7835 slashes. Case is converted to lower. Parts of URLs that do not
7836 correspond to files are left completely alone. [Ben Laurie]
7838 *) PORT: 2 new OSs added to the list of ports:
7839 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7840 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7842 *) Add the server version (SERVER_VERSION macro) to the "server
7843 configured and running" entry in the error_log. Also build an
7844 object file at link-time that contains the current time
7845 (SERVER_BUILT global const char[]), and include that in the
7848 *) Set r->headers_out when sending responses from the proxy.
7849 This fixes things such as the logging of headers sent from
7850 the proxy. [Marc Slemko] PR#659
7852 *) support/httpd_monitor is no longer distributed because the
7853 scoreboard should not be file based if at all possible. Use
7854 mod_status to see current server snapshot.
7856 *) (set_file_slot): New function, allowing auth directives to be
7857 independent of the server root, so the server documents can be
7858 moved to a different directory or machine more easily.
7859 [David J. MacKenzie]
7861 *) If no TransferLog is given explicitly, decline
7862 to log. This supports coexistence with other logging modules,
7863 such as the custom one that UUNET uses. [David J. MacKenzie]
7865 *) Check for titles in server-parsed HTML files.
7866 Ignore leading newlines and returns in titles. The old behavior
7867 of replacing a newline after <title> with a space causes the
7868 title to be misaligned in the listing. [David J. MacKenzie]
7870 *) Change mod_cern_meta to be configurable on a per-directory basis.
7871 [David J. MacKenzie]
7873 *) Add 'Include' directive to allow inclusion of configuration
7874 files within configuration files. [Randy Terbush]
7876 *) Proxy errors on connect() are logged to the error_log (nothing
7877 new); now they include the IP address and port that failed
7878 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7880 *) Various architectures now define USE_MMAP_FILES which causes
7881 the server to use mmap() for static files. There are two
7882 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7883 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7884 number of bytes written in one cycle from a single mmap()d object,
7885 default 32768). [Dean Gaudet]
7887 *) API: Added post_read_request API phase which is run right after reading
7888 the request from a client, or right after an internal redirect. It is
7889 useful for modules setting environment variables that depend only on
7890 the headers/contents of the request. It does not run during subrequests
7891 because subrequests inherit pretty much everything from the main
7892 request. [Dean Gaudet]
7894 *) Added mod_unique_id which is used to generate a unique identifier for
7895 each hit, available in the environment variable UNIQUE_ID.
7898 *) init_modules is now called after the error logs have been opened. This
7899 allows modules to emit information messages into the error logs.
7902 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7903 information for case where proxy module is not available. [Marc Slemko]
7905 *) PORT: Apache has need for mutexes to serialize its children around
7906 accept. In prior versions either fcntl file locking or flock file
7907 locking were used. The method is chosen by the definition of
7908 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7909 and FLOCK for flock(). New options have been added:
7910 - SYSVSEM to use System V style semaphores
7911 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7912 - USLOCK to use IRIX uslock
7913 Based on timing various techniques, the following changes were made
7915 - Linux 2.x uses flock instead of fcntl
7916 - Solaris 2.x uses pthreads
7917 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7918 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7919 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7920 Martijn Koster <m.koster@pobox.com>]
7922 *) PORT: The semantics of accept/select make it very desirable to use
7923 mutexes to serialize accept when multiple Listens are in use. But
7924 in the case where only a single socket is open it is sometimes
7925 redundant to serialize accept(). Not all unixes do a good job with
7926 potentially dozens of children blocked on accept() on the same
7927 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7928 the server will avoid serialization when listening on only one socket,
7929 and use serialization when listening on multiple sockets.
7930 [Dean Gaudet] PR#467
7932 *) Configure changes: TestLib replaced by TestCompile, which has
7933 some additional capability (such as doing a sanity check of
7934 the compiler and flags selected); the version of Solaris is now
7935 available via the #define value of SOLARIS2; IRIX n32bit libs
7936 now supported and selectable by new Configuration Rule: IRIXN32;
7937 We no longer default to -O2 optimization. [Jim Jagielski]
7939 *) Updated Configure: Configuration now uses AddModule to specify
7940 module source or binary file location, relative to src directory.
7941 Modules can be dropped into modules/extra, or in their own
7942 directory, and modules can come with a Makefile or Configure can
7943 create one. Modules can add compiler or library information to
7944 generated Makefiles. [Paul Sutton]
7946 *) Source core re-organisation: distributed modules are now in
7947 modules/standard. All other source code is in main. OS-specific
7948 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7950 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7953 *) Fix another long-standing bug in sub_req_lookup_file where it would
7954 happily skip past access checks on subdirectories looked up with
7955 relative paths. (It's used by mod_dir, mod_negotiation,
7956 and mod_include.) [Dean Gaudet]
7958 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7959 N is the number of <Directory> sections, and M is the number of
7960 components in the filename of an object.
7962 To achieve this optimization the following config changes were made:
7963 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7964 <Files>s, and <Location>s now treat a slash as a special
7965 character. For example "/home/*/public_html" previously would
7966 match "/home/a/andrew/public_html", now it only matches things
7967 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7968 - It's possible now to use [] wildcarding in <Directory>, <Files>
7970 - Regex <Directory>s are applied after all non-regex <Directory>s.
7974 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7975 and corrupted paths. [Dean Gaudet]
7977 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7978 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7979 be accessed now via backreferences $1..$9 in RewriteConds test-against
7980 strings in addition to RewriteRules subst string. Second the grouped
7981 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7982 via backreferences %1..%9 both in following RewriteCond test-against
7983 strings and RewriteRules subst string. This provides maximum flexibility
7984 through the use of backreferences.
7985 Additionally the rewriting engine was cleaned up by putting common
7986 code to the new expand_backrefs_inbuffer() function.
7987 [Ralf S. Engelschall]
7989 *) When merging the main server's <Directory> and <Location> sections into
7990 a vhost, put the main server's first and the vhost's second. Otherwise
7991 the vhost can't override the main server. [Dean Gaudet] PR#717
7993 *) The <Directory> code would merge and re-merge the same section after
7994 a match was found, possibly causing problems with some modules.
7997 *) ip-based vhosts are stored and queried using a hashing function, which
7998 has been shown to improve performance on servers with many ip-vhosts.
7999 Some other changes had to be made to accommodate this:
8000 - the * address for vhosts now behaves like _default_
8001 - the matching process now is:
8002 - match an ip-vhost directly via hash (possibly matches main
8004 - if that fails, just pretend it matched the main server
8005 - if so far only the main server has been matched, perform
8006 name-based lookups (ServerName, ServerAlias, ServerPath)
8007 *only on name-based vhosts*
8008 - if they fail, look for _default_ vhosts
8009 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
8011 *) dbmmanage overhaul:
8012 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
8013 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
8014 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
8015 - provide better seed for rand
8016 - prompt for password as per getpass(3) (turn off echo, read from
8018 - use "newstyle" crypt based on $Config{osname} ($^O)
8019 - will not add a user if already in database, use new `update' command
8021 - added `check' command to check a users' password
8022 - added `import' command to convert existing password text-files or
8023 dbm files exported with `view'
8024 - more descriptive usage, general cleanup, 'use strict' clean, etc.
8027 *) Added psocket() which is a pool form of socket(), various places within
8028 the proxy weren't properly blocking alarms while registering the cleanup
8029 for its sockets. bclose() now uses pclose() and pclosesocket(). There
8030 was a bug where the client socket was being close()d twice due a still
8031 registered cleanup. [Dean Gaudet]
8033 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
8036 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
8037 [Jason Venner <jason@idiom.com>] PR#667
8039 *) Enable ``=""'' for RewriteCond directives to match against
8040 the empty string. This is the preferred way instead of ``^$''.
8041 [Ralf S. Engelschall]
8043 *) Fixed an infinite loop in mod_imap for references above the server root
8044 [Dean Gaudet] PR#748
8046 *) mod_proxy now has a ReceiveBufferSize directive, similar to
8047 SendBufferSize, so that the TCP window can be set appropriately
8048 for LFNs. [Phillip A. Prindeville]
8050 *) mod_browser has been replaced by the more general mod_setenvif
8051 (courtesy of Paul Sutton). BrowserMatch* directives are still
8052 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
8053 UnSetEnvIfZero directives. [Ken Coar]
8055 *) "HostnameLookups double" forces double-reverse DNS to succeed in
8056 order for remote_host to be set (for logging, or for the env var
8057 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
8060 *) mod_access overhaul:
8061 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
8062 and cidr syntax (i.e. 10.1.0.0/16). PR#762
8063 - Critical path was sped up by pre-computing a few things at config time.
8064 - The undocumented syntax "allow user-agents" was removed,
8065 the replacement is "allow from env=foobar" combined with mod_browser.
8066 - When used with hostnames it now forces a double-reverse lookup
8067 no matter what the directory settings are. This double-reverse
8068 doesn't affect any of the other routines that use the remote
8069 hostname. In particular it's still passed to CGIs and the log
8070 without the double-reverse check. Related PR#860.
8073 *) When a large bwrite() occurs (larger than the internal buffer size),
8074 while there is already something in the buffer, apache will combine
8075 the large write and the buffer into a single writev(). (This is
8076 in anticipation of using mmap() for reading files.)
8079 *) In obscure cases where a partial socket write occurred while chunking,
8080 Apache would omit the chunk header/footer on the next block. Cleaned
8081 up other bugs/inconsistencies in error conditions in buff.c. Fixed
8082 a bug where a long pause in DNS lookups could cause the last packet
8083 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
8085 *) API: Added child_exit function to module structure. This is called
8086 once per "heavy-weight process" just before a server child exit()'s
8087 e.g. when max_requests_per_child is reached, etc.
8088 [Doug MacEachern, Dean Gaudet]
8090 *) mod_include cleanup showed that handle_else was being used to handle
8091 endif. It didn't cause problems, but it was cleaned up too.
8094 *) mod_cern_meta would attempt to find meta files for the directory itself
8095 in some cases, but not in others. It now avoids it in all cases.
8098 *) mod_mime_magic would core dump if there was a decompression error.
8099 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
8101 *) PORT: some variants of DGUX require -lsocket -lnsl
8102 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
8104 *) mod_autoindex now allows sorting of FancyIndexed directory listings
8105 by the various fields (name, size, et cetera), either in ascending
8106 or descending order. Just click on the column header. [Ken Coar]
8108 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
8109 CPUs like the Alpha. Apache still stores ints in pointers, but that's
8110 the relatively safe direction. [Dean Gaudet] PR#344
8112 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
8113 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
8115 *) child_main avoids an unneeded call to select() when there is only one
8116 listening socket. [Dean Gaudet]
8118 *) In the event that the server is starved for idle servers it will
8119 spawn 1, then 2, then 4, ..., then 32 servers each second,
8120 doubling each second. It'll also give a warning in the errorlog
8121 since the most common reason for this is a poor StartServers
8122 setting. The define MAX_SPAWN_RATE can be used to raise/lower
8123 the maximum. [Dean Gaudet]
8125 *) Apache now provides an effectively unbuffered connection for
8126 CGI scripts. This means that data will be sent to the client
8127 as soon as the CGI pauses or stops output; previously, Apache would
8128 buffer the output up to a fixed buffer size before sending, which
8129 could result in the user viewing an empty page until the CGI finished
8130 or output a complete buffer. It is no longer necessary to use an
8131 "nph-" CGI to get unbuffered output. Given that most CGIs are written
8132 in a language that by default does buffering (e.g. perl) this
8133 shouldn't have a detrimental effect on performance.
8135 "nph-" CGIs, which formerly provided a direct socket to the client
8136 without any server post-processing, were not fully compatible with
8137 HTTP/1.1 or SSL support. As such they would have had to implement
8138 the transport details, such as encryption or chunking, in order
8139 to work properly in certain situations. Now, the only difference
8140 between nph and non-nph scripts is "non-parsed headers".
8141 [Dean Gaudet, Sameer Parekh, Roy Fielding]
8143 *) If a BUFF is switched from buffered to unbuffered reading the first
8144 bread() will return whatever remained in the buffer prior to the
8145 switch. [Dean Gaudet]
8147 Changes with Apache 1.3a1
8149 *) Added another Configure helper script: TestLib. It determines
8150 if a specified library exists. [Jim Jagielski]
8152 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8153 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8156 *) PORT: Some architectures use size_t for various lengths in network
8157 functions such as accept(), and getsockname(). The definition
8158 NET_SIZE_T is used to control this. [Dean Gaudet]
8160 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8161 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8162 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8164 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8165 [Igor N Kovalenko <infoh@mail.wplus.net>]
8167 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8168 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8169 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8170 [Dean Gaudet] related PR#875
8172 *) API: Correct child_init() slot declaration from int to void, to
8173 match the init() declaration. Update mod_example to use the new
8176 *) added transport handle slot (t_handle) to the BUFF structure
8179 *) get_client_block() returns wrong length if policy is
8180 REQUEST_CHUNKED_DECHUNK.
8181 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
8183 *) Support the image map format of FrontPage. For example:

8187 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
8188 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
8190 *) AddModuleInfo directive for mod_info which allows you to annotate
8191 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8193 *) Added NoProxy directive to avoid using ProxyRemote for selected
8194 addresses. Added ProxyDomain directive to cause unqualified
8195 names to be qualified by redirection.
8196 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8198 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8199 header to the remote host in the proxy. [Sameer Parekh and
8202 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8203 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8204 URLs, fixed rewritelog(), fixed forced response code handling on
8205 redirects from within .htaccess files, disabled pipe locking under
8206 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8207 no substitution, bugfixed situations where HostnameLookups is off, made
8208 mod_rewrite more thread-safe for NT port and fixed problem when creating
8209 an empty query string via "xxx?".
8210 This update also removes the copyright of Ralf S. Engelschall,
8211 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8212 exclusively copyrighted by the Apache Group now. This happened because
8213 the author now has gifted mod_rewrite exclusively to the Apache Group and
8214 no longer maintains an external version.
8215 [Ralf S. Engelschall]
8217 *) API: Added child_init function to module structure. This is called
8218 once per "heavy-weight process" before any requests are handled.
8219 See http_config.h for more details. [Dean Gaudet]
8221 *) Anonymous_LogEmail was logging on each subrequest.
8222 [Dean Gaudet] PR#421, 868
8224 *) API: Added is_initial_req() which tests if the request being
8225 processed is the initial request, or a subrequest.
8228 *) Extended SSI (mod_include) now handles additional relops for
8229 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8231 *) Configure fixed to correctly propagate user-selected options and
8232 settings (such as CC and OPTIM) to Makefiles other than
8233 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8235 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8236 directory indices to start with the contents of the HeaderName file
8237 if there is one. If there isn't one, the behaviour is unchanged.
8238 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8240 *) WIN32: Modules can now be dynamically loaded DLLs using the
8241 LoadModule/LoadFile directives. Note that module DLLs must be
8242 compiled with the multithreaded DLL version of the runtime library.
8243 [Alexei Kosut and Ben Laurie]
8245 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8246 This allows the admin to completely remove automatic indexing
8247 from the server, while still supporting the basic functions of
8248 trailing-slash redirects and DirectoryIndex files. Note that if
8249 you're carrying over an old Configuration file and you use directory
8250 indexing then you'll want to add:
8252 Module autoindex_module mod_autoindex.o
8254 before mod_dir in your Configuration. [Dean Gaudet]
8256 *) popendir/pclosedir created to properly protect directory scanning.
8257 [Dean Gaudet] PR#525
8259 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8260 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8261 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8264 *) The AccessFileName directive can now take more than one filename.
8265 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8267 *) The new mod_mime_magic can be used to "magically" determine the type
8268 of a file if the extension is unknown. Based on the unix file(1)
8269 command. [Ian Kluft <ikluft@cisco.com>]
8271 *) We now determine and display the time spent processing a
8272 request if desired. [Jim Jagielski]
8274 *) mod_status: PID field of "dead" child slots no longer displays
8275 main httpd process's PID. [Jim Jagielski]
8277 *) Makefile.nt added - to build all the bits from the command line:
8278 nmake -f Makefile.nt
8279 Doesn't yet work properly. [Ben Laurie]
8281 *) Default text of 404 error is now "Not Found" rather than the
8282 potentially misleading "File Not Found". [Ken Coar]
8284 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8285 for the net if we require people that actually need this data to
8286 enable it. [Linus Torvalds]
8288 *) directory_walk() is an expensive function, keep a little more state to
8289 avoid needless string counting. Add two new functions make_dirstr_parent
8290 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8291 The new functions are a little less general than make_dirstr, but
8292 work more efficiently (less memory, less string counting).
8295 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8296 to LDFLAGS) to avoid complications with lex rules in make files.
8297 [Dean Gaudet] PR#372
8299 *) run_method optimized to avoid needless scanning over NULLs in the
8300 module list. [Dean Gaudet]
8302 *) Revamp of (unix) scoreboard management code such that it avoids
8303 unnecessary traversals of the scoreboard on each hit. This is
8304 particularly important for high volume sites with a large
8305 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8306 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8307 httpd.h. [Dean Gaudet]
8309 *) In configurations using multiple Listen statements it was possible for
8310 busy sockets to starve other sockets of service. [Dean Gaudet]
8312 *) Added hook so standalone_main can be replaced at compile time
8313 (define STANDALONE_MAIN)
8316 *) Lowest-level read/write functions in buff.c will be replaced with
8317 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8318 compile time. The default sfio discipline will behave as apache
8319 would without sfio compiled in.
8322 *) Enhance UserDir directive (mod_userdir) to accept a list of
8323 usernames for the 'disable' keyword, and add 'enable user...' to
8324 selectively *en*able userdirs if they're globally disabled.
8327 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8328 will work with Netscape dbm files. (dbmmanage will probably not
8329 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8331 *) Add a ListenBacklog directive to control the backlog parameter
8332 passed to listen(). Also change the default to 511 from 512.
8335 *) API: A new handler response DONE which informs apache that the
8336 request has been handled and it can finish off quickly, similar to
8337 how it handles errors. [Rob Hartill]
8339 *) Turn off chunked encoding after sending terminating chunk/footer
8340 so that we can't do it twice by accident. [Roy Fielding]
8342 *) mod_expire also issues Cache-Control: max-age headers.
8345 *) API: Added kill_only_once option for free_proc_chain so that it won't
8346 aggressively try to kill off specific children. For fastcgi.
8347 [Stanley Gambarin <gambarin@OpenMarket.com>]
8349 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8351 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8352 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8353 attributes in the FancyIndexing IMG tags. [Ken Coar]
8355 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8357 *) PORT: Added Windows NT support
8358 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8360 Changes with Apache 1.2.6
8362 *) mod_include when using XBitHack Full would send ETags in addition to
8363 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8364 [Dean Gaudet] PR#1133
8366 *) SECURITY: When a client connects to a particular port/addr, and
8367 gives a Host: header ensure that the virtual host requested can
8368 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8370 *) Support virtual hosts with wildcard port and/or multiple ports
8371 properly. [Ed Korthof <ed@organic.com>]
8373 *) Fixed some case-sensitivity issues according to RFC2068.
8376 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8377 and mod_include.c. [Dean Gaudet]
8379 *) Variable 'cwd' was being used pointlessly before being set.
8382 *) SIGURG doesn't exist on all platforms.
8383 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8385 *) When an error occurs during a POST, or other operation with a
8386 request body, the body has to be read from the net before allowing
8387 a keepalive session to continue. [Roy Fielding] PR#1399
8389 *) When an error occurs in fcntl() locking suggest the user look up
8390 the docs for LockFile. [Dean Gaudet]
8392 *) table_set() and table_unset() did not deal correctly with
8393 multiple occurrences of the same key. [Stephen Scheck
8394 <sscheck@infonex.net>, Ben Laurie] PR#1604
8396 *) send_fd_length() did not calculate total_bytes_sent properly in error
8397 cases. [Ben Reser <breser@regnow.com>] PR#1366
8399 *) r->connection->user was allocated in the wrong pool causing corruption
8400 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8402 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8403 Also removed the auto-generated link to www.apache.org that was the
8404 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8406 *) Multiple "close" tokens may have been set in the "Connection"
8407 header, not an error, but a waste.
8408 [Ronald.Tschalaer@psi.ch] PR#1683
8410 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8411 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8413 *) It appears the "257th byte" bug (see
8414 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8415 at the 256th byte as well. Fixed. [Dean Gaudet]
8417 *) mod_rewrite would not handle %3f properly in some situations.
8420 *) Apache could generate improperly chunked HTTP/1.1 responses when
8421 the bputc() or rputc() functions were used by modules (such as
8422 mod_include). [Dean Gaudet]
8424 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8425 some ports. [Ralf Engelschall]
8427 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8429 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8431 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8433 Changes with Apache 1.2.5
8435 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8436 only an issue on systems without a MAXDNAME define or where
8437 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8439 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8442 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8443 directory listings. [Marc Slemko]
8445 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8448 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8449 is used to read various types of files such as htaccess and
8450 htpasswd files. [Marc Slemko]
8452 *) SECURITY: Ensure that the buffer returned by ht_time is always
8453 properly null terminated. [Marc Slemko]
8455 *) SECURITY: General mod_include cleanup, including fixing several
8456 possible buffer overflows and a possible infinite loop. This cleanup
8457 was done against 1.3 code and then backported to 1.2, the result
8458 is a large difference (due to indentation cleanup in 1.3 code).
8459 Users interested in seeing a smaller set of relevant differences
8460 should consider comparing against src/modules/standard/mod_include.c
8461 from the 1.3b3 release. Non-indentation changes to mod_include
8462 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8464 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8465 including fixing a possible buffer overflow. This cleanup also
8466 was done with 1.3 code as a basis, see the the previous note
8467 about mod_include. [Dean Gaudet]
8469 *) SECURITY: If a htaccess file can not be read due to bad
8470 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8471 The previous behavior was to ignore the htaccess file if it could not
8472 be read. This change may make some setups with unreadable
8473 htaccess files stop working. PR#817 [Marc Slemko]
8475 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8476 Make it O(n). This inefficiency could be used to mount a denial
8477 of service attack against the Apache server. Thanks to

8487 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8489 *) mod_userdir was modifying r->finfo in cases where it wasn't setting

8496 *) Inetd mode (which is buggy) uses timeouts without having setup the
8497 jmpbuffer. [Dean Gaudet] PR#1064
8499 *) Work around problem under Linux where a child will start looping
8500 reporting a select error over and over.
8501 [Rick Franchuk <rickf@transpect.net>] PR#1107
8503 Changes with Apache 1.2.4
8505 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8506 always making requests with the full-URI instead of just the URI path.

8509 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8510 on this platform. [Marc Slemko]
8512 Changes with Apache 1.2.3
8514 *) The request to a remote proxy was mangled if it was generated as the
8515 result of a ProxyPass directive. URL schemes other than http:// were not
8516 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
8517 PR#812 [Lars Eilebrecht]
8519 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8520 information for case where proxy module is not available. [Marc Slemko]
8522 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8523 do for errors and cached responses. [Roy Fielding]
8525 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8527 Changes with Apache 1.2.2 [not released]
8529 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8530 happily skip past access checks on subdirectories looked up with relative
8531 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8534 *) Add lockfile name to error message printed out when
8535 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8538 *) Enhanced the chunking and error handling inside the buffer functions.
8539 [Dean Gaudet, Roy Fielding]
8541 *) When merging the main server's <Directory> and <Location> sections into
8542 a vhost, put the main server's first and the vhost's second. Otherwise
8543 the vhost can't override the main server. [Dean Gaudet] PR#717
8545 *) The <Directory> code would merge and re-merge the same section after
8546 a match was found, possibly causing problems with some modules.
8549 *) Fixed an infinite loop in mod_imap for references above the server root.
8550 [Dean Gaudet] PR#748
8552 *) mod_include cleanup showed that handle_else was being used to handle
8553 endif. It didn't cause problems, but it was cleaned up too.
8556 *) Last official synchronization of mod_rewrite with author version (because
8557 mod_rewrite is now directly developed by the author at the Apache Group):
8558 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8559 minus WIN32/NT stuff, but plus copyright removement.
8561 - workaround for detecting infinite rewriting loops
8562 - fixed setting of env vars when "-" is used as subst string
8563 - fixed forced response code on redirects (PR#777)
8564 - fixed cases where r->args is ""
8565 - kludge to disable locking on pipes under braindead SunOS
8566 - fix for rewritelog in cases where remote hostname is unknown
8567 - fixed totally damaged request_rec walk-back loop
8568 o remove static from local data and add static to global ones.
8569 o replaced ugly proxy finding stuff by simple
8570 find_linked_module("mod_proxy") call.
8571 o added missing negation char on rewritelog()
8572 o fixed a few comment typos
8573 [Ralf S. Engelschall]
8575 *) Anonymous_LogEmail was logging on each subrequest.
8576 [Dean Gaudet] PR#421, PR#868
8578 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8579 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8580 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8581 Additionally mod_browser now triggers during translate_name to workaround
8582 a deficiency in the header_parse phase.

8590 [Marc Slemko] PR#848
8592 *) The proxy didn't treat the "Host:" keyword of the host header as case-
8593 insensitive. The proxy would corrupt the first line of a response from
8594 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814

8599 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
8600 under Solaris 2.x (up through 2.5.1). It has been fixed.
8601 [Dean Gaudet] PR#832
8603 *) API: In HTTP/1.1, whether or not a request message contains a body
8604 is independent of the request method and based solely on the presence
8605 of a Content-Length or Transfer-Encoding. Therefore, our default
8606 handlers need to be prepared to read a body even if they don't know
8607 what to do with it; otherwise, the body would be mistaken for the
8608 next request on a persistent connection. discard_request_body()
8609 has been added to take care of that. [Roy Fielding] PR#378
8611 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
8612 release version number, such that it always increases along the
8613 same lines as our source code branching. [Roy Fielding]
8615 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
8617 Changes with Apache 1.2.1
8619 *) SECURITY: Don't serve file system objects unless they are plain files,
8620 symlinks, or directories. This prevents local users from using pipes
8621 or named sockets to invoke programs for an extremely crude form of
8624 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
8625 could contain "../" allowing a local user to "publish" any file on
8626 the system. No slashes are allowed now. [Dean Gaudet]
8628 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8629 (headers, readmes, titles), mod_negotiation (type maps), or
8630 mod_cern_meta (meta files). [Dean Gaudet]
8632 *) SECURITY: Apache will refuse to run as "User root" unless
8633 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8635 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8636 if it contained a .htaccess disallowing symlinks. This is contrary
8637 to the rule that symlink permissions are tested with the symlink
8638 options of the parent directory. [Dean Gaudet] PR#353
8640 *) CONFIG: The LockFile directive can be used to place the serializing
8641 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8642 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8645 *) Request processing now retains state of whether or not the request
8646 body has been read, so that internal redirects and subrequests will
8647 not try to read it twice (and block). [Roy Fielding]
8649 *) Add a placeholder in modules/Makefile to avoid errors with certain
8650 makes. [Marc Slemko]
8652 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
8653 [Dean Gaudet] PR#644
8655 *) mod_include was not properly changing the current directory.
8656 [Marc Slemko] PR#742
8658 *) Attempt to work around problems with third party libraries that do not
8659 handle high numbered descriptors (examples include bind, and
8660 solaris libc). On all systems apache attempts to keep all permanent
8661 descriptors above 15 (called the low slack line). Solaris users
8662 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8663 which keeps all non-FILE * descriptors above 255. On all systems
8664 this should make supporting large numbers of vhosts with many open
8665 log files more feasible. If this causes trouble please report it,
8666 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8667 [Dean Gaudet] various PRs
8669 *) Related to the last entry, network sockets are now opened before
8670 log files are opened. The only known case where this can cause
8671 problems is under Solaris with many virtualhosts and many Listen
8672 directives. But using -DHIGH_SLACK_LINE=256 described above will
8673 work around this problem. [Dean Gaudet]
8675 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8678 *) Improved unix error response logging. [Marc Slemko]
8680 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8681 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8682 when a URL http://... was used in conjunction with a special
8683 redirect flag, e.g. R=permanent, the permanent status was lost.

8720 Changes with Apache 1.2b11
8722 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
8724 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
8725 [Doug MacEachern, Rob Hartill]
8727 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
8728 reading from one buffer and writing to another, at least until it has
8729 a custom timeout handler. [Roy Fielding and Petr Lampa]
8731 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
8732 apparently due to a mismatch between sigaction and setjmp.
8733 [Roy Fielding] PR#502
8735 *) Log correct status code if we timeout before receiving a request (408)
8736 or if we received a request-line that was too long to process (414).
8737 [Ed Korthof and Roy Fielding] PR#601
8739 *) Virtual hosts with the same ServerName, but on different ports, were
8740 not being selected properly. [Ed Korthof]
8742 *) Added code to return the requested IP address from proxy_host2addr()
8743 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
8744 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8745 [Chuck Murcko] PR#614
8747 *) If multiple requests on a single connection are used to retrieve
8748 data from different virtual hosts, the virtual host list would be
8749 scanned starting with the most recently used VH instead of the first,
8750 causing most virtual hosts to be ignored.

8753 *) The OS/2 handling of process group was broken by a porting patch for
8754 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
8756 *) Inherit virtual server port from main server if none (or "*") is
8757 given for VirtualHost. [Dean Gaudet] PR#576
8759 *) If the lookup for a DirectoryIndex name with content negotiation
8760 has found matching variants, but none are acceptable, return the
8761 negotiation result if there are no more DirectoryIndex names to lookup.
8762 [Petr Lampa and Roy Fielding]
8764 *) If a soft_timeout occurs after keepalive is set, then the main child
8765 loop would try to read another request even though the connection
8766 has been aborted. [Roy Fielding]
8768 *) Configure changes: Allow for whitespace at the start of a
8769 Module declaration. Also, be more understanding about the
8770 CC=/OPTIM= format in Configuration. Finally, fix compiler
8771 flags if using HP-UX's cc compiler. [Jim Jagielski]
8773 *) Subrequests and internal redirects now inherit the_request from the
8774 original request-line. [Roy Fielding]
8776 *) Test for error conditions before creating output header fields, since
8777 we don't want the error message to include those fields. Likewise,
8778 reset the content_language(s) and content_encoding of the response
8779 before generating or redirecting to an error message, since the new
8780 message will have its own Content-* definitions. [Dean Gaudet]
8782 *) Restored the semantics of headers_out (headers sent only with 200..299
8783 and 304 responses) and err_headers_out (headers sent with all responses).
8784 Avoid the overhead of copying tables if err_headers_out is empty
8785 (the usual case). [Roy Fielding]
8787 *) Fixed a couple places where a check for the default Content-Type was
8788 not properly checking both the value configured by the DefaultType
8789 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8790 of DEFAULT_TYPE to match the documented default (text/plain).
8791 [Dean Gaudet] PR#506
8793 *) Escape the HTML-sensitive characters in the Request-URI that is
8794 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8796 *) Properly initialize the flock structures used by the mutex locking
8797 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8800 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8801 (and NCSA httpd) definition wherein it was the extra path info beyond
8802 the CGI script filename. The environment variable FILEPATH_INFO has
8803 been removed, and instead we supply the original REQUEST_URI to any
8804 script that wants to be Apache-specific and needs the real URI path.
8805 This solves a problem with existing scripts that use extra path info
8806 in the ScriptAlias directive to pass options to the CGI script.
8809 *) The _default_ change in 1.2b10 will change the behaviour on configs
8810 that use multiple Listen statements for listening on multiple ports.
8811 But that change is necessary to make _default_ consistent with other
8812 forms of <VirtualHost>. It requires such configs to be modified
8813 to use <VirtualHost _default_:*>. The documentation has been
8814 updated. [Dean Gaudet] PR#530
8816 *) If an ErrorDocument CGI script is used to respond to an error
8817 generated by another CGI script which has already read the message
8818 body of the request, the server would block trying to read the
8819 message body again. [Rob Hartill]
8821 *) signal() replacement conflicted with a define on QNX (and potentially
8822 other platforms). Fixed. [Ben Laurie] PR#512
8824 Changes with Apache 1.2b10
8826 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8827 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8829 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8831 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]

8834 config, in case the hostent struct returned is trash.
8835 [Chuck Murcko] PR #491
8837 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8838 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8840 Changes with Apache 1.2b9 [never announced]
8842 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8843 changes and in anticipation of 1.2 final release. [Roy Fielding]
8845 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8846 the connection (e.g., when user presses Stop). Apache will now stop
8847 trying to send a message body immediately after an error from write.
8848 [Roy Fielding and Nathan Kurz] PR#335
8850 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8851 than mod_alias, and mod_alias has higher priority than mod_proxy;
8852 rearranged other modules to enhance understanding of their purpose
8853 and relative order (and maybe even reduce some overhead).
8854 [Roy Fielding and Sameer Parekh]
8856 *) Fix graceful restart. Eliminate many signal-related race
8857 conditions in both forms of restart, and in SIGTERM. See
8858 htdocs/manual/stopping.html for details on stopping and
8859 restarting the parent. [Dean Gaudet]
8861 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8862 memory allocator to avoid a behaviour that required extra blocks to
8863 be allocated. [Dean Gaudet]
8865 *) Allow suexec to access files relative to current directory but not
8866 above. (Excluding leading / or any .. directory.) [Ken Coar]
8869 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8870 PR#367, 368, 354, 453
8872 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8873 while obtaining the /~user and save the username in a separate data
8874 area so that it won't be overwritten by the call to getgrgid(), and
8875 fix some misuse of the pool string allocation functions. Also fixes
8876 a general problem with parsing URL query info into args for CGI scripts.

8884 AuthDBAuthoritative. [Marc Slemko] PR#420
8886 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8888 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8889 object that can't be PUT, or FOOBAR for some method FOOBAR that
8890 apache doesn't know about at all). Log 404s that occur in mod_include.
8891 [Paul Sutton, John Van Essen]
8893 *) If a soft timeout (or lingerout) occurs while trying to flush a
8894 buffer or write inside buff.c or fread'ing from a CGI's output,
8895 then the timeout would be ignored. [Roy Fielding] PR#373
8897 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8898 parsing of headers. If the terminating empty-line CRLF occurs starting
8899 at the 256th or 257th byte of output, then Navigator will think a normal
8900 image is invalid. We are guessing that this is because their initial
8901 read of a new request uses a 256 byte buffer. We check the bytes written
8902 so far and, if we are about to tickle the bug, we instead insert a
8903 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8905 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8906 of an external redirection. [Roy Fielding and Paul Sutton]
8908 *) Configure would create a broken Makefile if the configuration file
8909 contained a commented-out Rule. [Roy Fielding]
8911 *) Promote per_dir_config and subprocess_env from the subrequest to the
8912 main request in mod_negotiation. In particular this fixes a bug
8913 where <Files> sections wouldn't properly apply to negotiated content.
8916 *) Fix a potential deadlock in mod_cgi script_err handling.
8917 [Ralf S. Engelschall]
8919 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8922 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8923 .htaccess files because the RewriteBase was not replaced correctly.
8924 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8925 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8927 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8928 1.x the settings are those of pre-1.2b8. For 2.x we include
8929 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8930 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8931 [Dean Gaudet] PR#336, PR#340
8933 *) Redirect did not preserve ?query_strings when present in the client's
8934 request. [Dean Gaudet]
8936 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8938 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8940 *) Add UnixWare compile/install instructions. [Chuck Murcko]

8944 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8946 *) Improve handling of directories when filenames have spaces in them.
8949 *) For hosts with multiple IP addresses, try all additional addresses if
8950 necessary to get a connect. Fail only if hostent address list is
8951 exhausted. [Chuck Murcko]
8953 *) More signed/unsigned port fixes. [Dean Gaudet]
8955 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8958 Changes with Apache 1.2b8
8960 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8961 to it. [Marc Slemko]
8963 *) The addition of <Location> and <File> directives made the
8964 sub_req_lookup_simple() function bogus, so we now handle
8965 the special cases directly. [Dean Gaudet]
8967 *) We now try to log where the server is dumping core when a fatal
8968 signal is received. [Ken Coar]
8970 *) Improved lingering_close by adding a special timeout, removing the
8971 spurious log messages, removing the nonblocking settings (they
8972 are not needed with the better timeout), and adding commentary
8973 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8974 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8976 *) Send error messages about setsockopt failures to the server error
8977 log instead of stderr. [Roy Fielding]
8979 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8981 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8982 processing a subrequest, allocate memory from r->main->pool instead
8983 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8984 in the middle of an SSI request. [Dean Gaudet] PR #122
8986 *) Fixed status of response when POST is received for a nonexistent URL
8987 (was sending 405, now 404) and when any method is sent with a
8988 full-URI that doesn't match the server and the server is not acting
8989 as a proxy (was sending 501, now 403). [Roy Fielding]
8991 *) Host port changed to unsigned short. [Ken Coar] PR #276
8993 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8995 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8997 *) Report extra info from errno with many errors that cause httpd to exit.
8998 spawn_child, popenf, and pclosef now have valid errno returns in the
8999 event of an error. Correct problems where errno was stomped on
9000 before being reported. [Dean Gaudet]
9002 *) In the proxy, if the cache filesystem was full, garbage_coll() was
9003 never called, and thus the filesystem would remain full indefinitely.
9004 We now also remove incomplete cache files left if the origin server
9005 didn't send a Content-Length header and either the client has aborted
9006 transfer or bwrite() to client has failed. [Petr Lampa]
9008 *) Fixed the handling of module and script-added header fields.
9009 Improved the interface for sending header fields and reduced
9010 the duplication of code between sending okay responses and errors.
9011 We now always send both headers_out and err_headers_out, and
9012 ensure that the server-reserved fields are not being overridden,
9013 while not overriding those that are not reserved. [Roy Fielding]
9015 *) Moved transparent content negotiation fields to err_headers_out
9016 to reflect above changes. [Petr Lampa]
9018 *) Fixed the determination of whether or not we should make the
9019 connection persistent for all of the cases where some other part
9020 of the server has already indicated that we should not. Also
9021 improved the ordering of the test so that chunked encoding will
9022 be set whenever it is desired instead of only when KeepAlive
9023 is enabled. Added persistent connection capability for most error
9024 responses (those that do not indicate a bad input stream) when
9025 accessed by an HTTP/1.1 client. [Roy Fielding]
9027 *) Added missing timeouts for sending header fields, error responses,
9028 and the last chunk of chunked encoding, each of which could have
9029 resulted in a process being stuck in write forever. Using soft_timeout
9030 requires that the sender check for an aborted connection rather than
9031 continuing after an EINTR. Timeouts that used to be initiated before
9032 send_http_header (and never killed) are now initiated only within or
9033 around the routines that actually do the sending, and not allowed to
9034 propagate above the caller. [Roy Fielding]
9036 *) mod_auth_anon required an @ or a . in the email address, not both.
9039 *) per_dir_defaults weren't set correctly until directory_walk for
9040 name-based vhosts. This fixes an obscure bug with the wrong config
9041 info being used for vhosts that share the same ip as the server.
9044 *) Improved generation of modules/Makefile to be more generic for
9045 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
9047 *) Generate makefile dependency for Configuration based on the actual
9048 name given when running the Configure process. [Dean Gaudet]
9050 *) Fixed problem with vhost error log not being set prior to
9051 initializing virtual hosts. [Dean Gaudet]
9053 *) Fixed infinite loop when a trailing slash is included after a type map
9054 file URL (extra path info). [Petr Lampa]
9056 *) Fixed server status updating of per-connection counters. [Roy Fielding]
9058 *) Add documentation for DNS issues (reliability and security), and try
9059 to explain the virtual host matching process. [Dean Gaudet]
9061 *) Try to continue gracefully by disabling the vhost if a DNS lookup
9062 fails while parsing the configuration file. [Dean Gaudet]
9064 *) Improved calls to setsockopt. [Roy Fielding]
9066 *) Negotiation changes: Don't output empty content-type in variant list;
9067 Output charset in variant list; Return sooner from handle_multi() if
9068 no variants found; Add handling of '*' wildcard in Accept-Charset.
9069 [Petr Lampa and Paul Sutton]
9071 *) Fixed overlaying of request/sub-request notes and headers in
9072 mod_negotiation. [Dean Gaudet]
9074 *) If two variants' charset quality are equal and one is the default
9075 charset (iso-8859-1), then prefer the variant that was specifically
9076 listed in Accept-Charset instead of the default. [Petr Lampa]
9078 *) Memory allocation problem in push_array() -- it would corrupt memory
9079 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
9081 *) invoke_handler() doesn't handle mime arguments in content-type
9084 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
9087 *) Fixed problem with ErrorDocument not working for virtual hosts
9088 due to one of the performance changes in 1.2b7. [Dean Gaudet]
9090 *) Log an error message if we get a request header that is too long,
9091 since it may indicate a buffer overflow attack. [Marc Slemko]
9093 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
9094 not reject URLs without a double-slash, as per RFC2068 section 3.2.
9095 [Ken Coar] PR #146, #187
9097 *) Added table entry placeholder for new header_parser callback
9098 in all of the distributed modules. [Ken Coar] PR #191
9100 *) Allow for cgi files without the .EXE extension on them under OS/2.
9101 [Garey Smiley] PR #59
9103 *) Fixed error message when resource is not found and URL contains
9104 path info. [Petr Lampa and Dean Gaudet] PR #40
9106 *) Fixed user and server confusion over what should be a virtual host
9107 and what is the main server, resulting in access to something
9108 other than the name defined in the virtualhost directive (but
9109 with the same IP address) failing. [Dean Gaudet]
9111 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
9112 AIX; improves the redirection stuff to enable the users to generally
9113 redirect to http, https, gopher and ftp; added TIME variable for
9114 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
9115 special patterns >STRING, <STRING and =STRING to RewriteCond, which
9116 can be used in conjunction with %{TIME} or other variables to create
9117 time-dependent rewriting rules. [Ralf S. Engelschall]
9119 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
9120 Module authors may need to adjust their code for proper cleanup to take
9121 place (that is, call note_cleanups_for_fd()). This change fixes problems
9122 with file descriptors being erroneously closed when the proxy module was
9123 in use. [Ben Laurie]
9125 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
9126 initgroups() to hose the group information needed for later
9127 comparisons. [Randy Terbush]
9129 *) Remove unnecessary call to va_end() in create_argv() which
9130 caused a SEGV on some systems.
9132 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
9135 *) Clear memory allocated for listeners. [Randy Terbush]
9137 *) Improved handling of IP address as a virtualhost address and
9138 introduced "_default_" as a synonym for the default vhost config.
9139 [Dean Gaudet] PR #212
9141 Changes with Apache 1.2b7
9143 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
9145 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
9147 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
9148 - replace protocol response numbers with symbols
9149 - save variant-list into main request notes
9150 - free allocated memory from subrequests
9151 - merge notes, headers_out and err_headers_out
9153 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
9154 "HTTP/#.# ###*" to be more lenient about what we accept.
9157 *) more proxy FTP bug fixes:
9158 - Changed send_dir() to remove user/passwd from displayed URL.
9159 - Changed login error messages to be more descriptive.
9160 - remove setting of SO_DEBUG socket option
9161 - Make ftp_getrc() more lenient about multiline responses,
9162 specifically, 230 responses which don't have continuation 230-
9163 on each line). These seem to be all NT FTP servers, and while
9164 perhaps questionable, they appear to be legal by RFC 959.
9165 - Add missing kill_timeout() after transfer to user completes.
9168 *) Fixed problem where a busy server could hang when restarting
9169 after being sent a SIGHUP due to child processes not exiting.
9172 *) Modify mod_include escaping so a '\' only signifies an escaped
9173 character if the next character is one that needs
9174 escaping. [Ben Laurie]
9176 *) Eliminated possible infinite loop in mod_imap when relative URLs are
9177 used with a 'base' directive that does not have a '/' in it.
9178 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
9180 *) Reduced the default timeout from 1200 seconds to 300, and the
9181 one in the sample configfile from 400 to 300. [Marc Slemko]
9183 *) Stop vbprintf from crashing if given a NULL string pointer;
9184 print (null) instead. [Ken Coar]
9186 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
9187 [Marc Slemko and Roy Fielding]
9189 *) Fixed problem with mod_cgi-generated internal redirects trying to
9190 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9192 *) Reduced timeout on lingering close, removed possibility of a blocked
9193 read causing the child to hang, and stopped logging of errors if
9194 the socket is not connected (reset by client). [Roy Fielding]
9196 *) Rearranged main child loop to remove duplication of code in
9197 select/accept and keep-alive requests, fixed several bugs regarding
9198 checking scoreboard_image for exit indication and failure to
9199 account for all success conditions and trap all error conditions,
9200 prevented multiple flushes before closing the socket; close the entire
9201 socket buffer instead of just one descriptor, prevent logging of
9202 EPROTO and ECONNABORTED on platforms where supported, and generally
9203 improved readability. [Roy Fielding]
9205 *) Extensive performance improvements. Cleaned up inefficient use of
9206 auto initializers, multiple is_matchexp calls on a static string,
9207 and excessive merging of response_code_strings. [Dean Gaudet]
9209 *) Added double-buffering to mod_include to improve performance on
9210 server-side includes. [Marc Slemko]
9212 *) Several fixes for suexec wrapper. [Randy Terbush]
9213 - Make wrapper work for files on NFS filesystem.
9214 - Fix portability problem of MAXPATHLEN.
9215 - Fix array overrun problem in clean_env().
9216 - Fix allocation of PATH environment variable
9218 *) Removed extraneous blank line is description of mod_status chars.
9221 *) Logging of errors from the call_exec routine simply went nowhere,
9222 since the logfile fd has been closed, so now we send them to stderr.
9223 [Harald T. Alvestrand]
9225 *) Fixed core dump when DocumentRoot is a CGI.
9226 [Ben Laurie, reported by geddis@tesserae.com]
9228 *) Fixed potential file descriptor leak in mod_asis; updated it and
9229 http_core to use pfopen/pfclose instead of fopen/fclose.
9230 [Randy Terbush and Roy Fielding]
9232 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9233 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9234 [Dean Gaudet and Ken Coar]
9236 *) Return a 302 response code to the client when sending a redirect
9237 due to a missing trailing '/' on a directory instead of a 301; now
9238 it is cacheable. [Markus Gyger]
9240 *) Fix condition where, if a bad directive occurs in .htaccess, and
9241 sub_request() goes first to this directory, then log_reason() will
9242 SIGSEGV because it doesn't have initialized r->per_dir_config.
9243 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9245 *) Fix handling of lang_index in is_variant_better(). This was
9246 causing problems which resulted in the server sending the
9247 wrong language document in some cases. [Petr Lampa]
9249 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9250 the clean environment on some systems.
9252 *) Tweak byteserving code (e.g. serving PDF files) to work around
9253 bugs in Netscape Navigator and Microsoft Internet Explorer.
9254 Emit Content-Length header when sending multipart/byteranges.
9257 *) Port to HI-UX/WE2. [Nick Maclaren]
9259 *) Port to HP MPE operating system for HP 3000 machines
9260 [Mark Bixby <markb@cccd.edu>]
9262 *) Fixed bug which caused a segmentation fault if only one argument
9263 given to RLimit* directives. [Ed Korthof]
9265 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9267 *) Improved buffered output to the client by delaying the flush decision
9268 until the BUFF code is actually about to read the next request.
9269 This fixes a problem introduced in 1.2b5 with clients that send
9270 an extra CRLF after a POST request. Also improved chunked output
9271 performance by combining writes using writev() and removing as
9272 many bflush() calls as possible. NOTE: Platforms without writev()
9273 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9274 or Configure, unless we have already done so. [Dean Gaudet]
9276 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9278 *) Fixed mod_info output corruption bug introduced by buffer overflow
9279 fixes. [Dean Gaudet]
9281 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9282 for the special case of a 304 response. [Paul Sutton]
9284 *) Improved handling of TRACE method by bypassing normal method handling
9285 and header parsing routines; fixed Allow response to always allow TRACE.
9288 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9290 *) Cleaned-up some of the generated HTML. [Ken Coar]
9292 Changes with Apache 1.2b6
9294 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9296 *) Fix typo introduced in fix for potential infinite loop around
9297 accept() in child_main(). This change caused the rev to 1.2b6.
9298 1.2b5 was never a public beta.
9300 Changes with Apache 1.2b5
9302 *) Change KeepAlive semantics (On|Off instead of a number), add
9303 MaxKeepAliveRequests directive. [Alexei Kosut]
9305 *) Various NeXT compilation patches, as well as a change in
9306 regex/regcomp.c since that file also used a NEXT define.
9309 *) Allow * to terminate the end of a directory match in mod_dir.
9310 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9312 *) Don't call can_exec() if suexec_enabled. Calling this requires
9313 scripts executed by the suexec wrapper to be world executable, which
9314 defeats one of the advantages of running the wrapper. [Randy Terbush]
9316 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9319 *) Migration from sprintf() to snprintf() to avoid buffer
9320 overflows. [Marc Slemko]
9322 *) Provide portable snprintf() implementation (ap_snprintf)
9323 as well as *cvt family. [Jim Jagielski]
9325 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9328 *) Remove mod_fastcgi.c from the distribution. This module appears
9329 to be maintained more through the Open Market channels and should
9330 continue to be easily available at http://www.fastcgi.com/
9332 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9333 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9335 *) mod_info assumed that the config files were relative to ServerRoot.
9338 *) CGI scripts called as an error document resulting from failed
9339 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9341 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9344 *) Properly check errno to prevent display of a directory index
9345 when server receives a long enough URL to confuse stat().
9348 *) Several security enhancements to suexec wrapper. It is _highly_
9349 recommended that previously installed versions of the wrapper
9350 be replaced with this version. [Randy Terbush, Jason Dour]
9352 - ~user execution now properly restricted to ~user's home
9353 directory and below.
9354 - execution restricted to UID/GID > 100
9355 - restrict passed environment to known variables
9356 - call setgid() before initgroups() (portability fix)
9357 - remove use of setenv() (portability fix)
9359 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9361 *) Add access control via environment variables. [Ben Laurie]
9363 *) Add rflush() function. [Alexei Kosut]
9365 *) remove duplicate pcalloc() call in new_connection().
9367 *) Fix incorrect comparison which could allow number of children =
9368 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9369 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9371 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9372 AIX PS/2, CONVEXOS. [Jim Jagielski]
9374 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9375 It's more portable. [Martin Kraemer]
9377 *) Replace references to make in Makefile.tmpl with $(MAKE).
9380 *) Add ProxyBlock directive w/IP address caching. Add IP address
9381 caching to NoCache directive as well. ProxyBlock works with all
9382 handlers; NoCache now also works with FTP for anonymous logins.
9383 Still more code cleanup. [Chuck Murcko]
9385 *) Add "header parse" API hook [Ben Laurie]
9387 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9389 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9391 *) Correctly allow access and auth directives in <Files> sections in
9392 server config files. [Alexei Kosut]
9394 *) Fix bug with ServerPath that could cause certain files to be not
9395 found by the server. [Alexei Kosut]
9397 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9398 double-quote from text and so that it properly checks for unsupported
9399 status codes using the new index_of_response interface. [Roy Fielding]
9401 *) Multiple fixes to the lingering_close code in order to avoid being
9402 interrupted by a stray timeout, to avoid lingering on a connection
9403 that has already been aborted or never really existed, to ensure that
9404 we stop lingering as soon as any error condition is received, and to
9405 prevent being stuck indefinitely if the read blocks. Also improves
9406 reporting of error conditions. [Marc Slemko and Roy Fielding]
9408 *) Fixed initialization of parameter structure for sigaction.
9409 [mgyger@itr.ch, Adrian Filipi-Martin]
9411 *) Fixed reinitializing the parameters before each call to accept and
9412 select, and removed potential for infinite loop in accept.
9413 [Roy Fielding, after useful PR from adrian@virginia.edu]
9415 *) Fixed condition where, if a child fails to fork, the scoreboard would
9416 continue to say SERVER_STARTING forever. Eventually, the main process
9417 would refuse to start new children because count_idle_servers() will
9418 count those SERVER_STARTING entries and will always report that there
9419 are enough idle servers. [Phillip Vandry]
9421 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9422 Avoided calling bflush() when the client is pipelining requests.
9423 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9425 *) Added description of "." mode in server-status [Jim Jagielski]
9427 Changes with Apache 1.2b4
9429 *) Fix possible race condition in accept_mutex_init() that
9430 could leave a small security hole open allowing files to be
9431 overwritten in cases where the server UID has write permissions.
9434 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9436 *) Fix portablity problem in util_script where ARG_MAX may not be
9437 defined for some systems.
9439 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9442 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9443 style magic #! token for better script portability. [Garey Smiley]
9445 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9446 execution for ~userdir CGI. [Jason Dour]
9448 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9450 *) Fix month off by one in suexec wrapper logging.
9452 Changes with Apache 1.2b3:
9454 *) Fix error in mod_cgi which could cause resources not to be properly
9455 freed, or worse. [Dean Gaudet]
9457 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9459 *) Add set_flag_slot() at the request of Dirk and others.
9462 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9464 *) Add changes to improve the error message given for invalid
9465 ServerName parameters. [Dirk vanGulik]
9467 *) Add "Authoritative" directive for Auth modules that don't
9468 currently have it. This gives admin control to assign authoritative
9469 control to an authentication scheme and allow "fall through" for
9470 those authentication modules that aren't "Authoritative" thereby
9471 allowing multiple authentication mechanisms to be chained.
9474 *) Remove requirement for ResourceConfig/AccessConfig if not using
9475 the three config file layout. [Randy Terbush]
9477 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9479 *) Changes to suexec wrapper to fix the following problems:
9480 1. symlinked homedirs will kill ~userdirs.
9481 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9482 3. CGI command lines paramters problems
9483 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9484 [Randy Terbush, Jason Dour]
9486 *) Change create_argv() to accept variable arguments. This fixes
9487 a problem where arguments were not getting passed to the CGI via
9488 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9490 *) Collapse multiple slashes in path URLs to properly apply
9491 handlers defined by <Location>. [Alexei Kosut]
9493 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9495 *) Improve the accuracy of request duration timings by setting
9496 r->request_time in read_request_line() instead of read_request().
9499 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9500 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9502 *) Add the ability to pass different Makefile.tmpl files to Configure
9503 using the -make flag. [Rob Hartill]
9505 *) Fix coredump triggered when sending a SIGHUP to the server caused
9506 by an assertion failure, in turn caused by an uninitialised field in a
9510 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9511 PATH_INFO from previous versions of Apache (in certain situations,
9512 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9513 [later removed in 1.2b11]
9515 *) Add rwrite() function to API to allow for sending strings of
9516 arbitrary length. [Doug MacEachern]
9518 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9520 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9521 NeXT. [Jim Jagielski]
9523 *) Removed recent modification to promote the status code on internal
9524 redirects, since the correct fix was to change the default log format
9525 in mod_log_config so that it outputs the original status. [Rob Hartill]
9527 Changes with Apache 1.2b2:
9529 *) Update set_signals() to use sigaction() for setting handlers.
9530 This appears to fix a re-entrant problem in the seg_fault()
9531 bus_error() handlers. [Randy Terbush]
9533 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9535 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9537 *) proxy_http.c bugfixes: [Chuck Murcko]
9538 1) fixes possible NULL pointer reference w/NoCache
9539 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9540 host would cache nothing if it was in the local domain,
9541 and the local domain was in the NoCache list)
9542 3) Adds Host: header when not available
9543 4) Some code cleanup and clarification
9545 *) mod_include.c bugfixes:
9546 1) Fixed an ommission that caused include variables to not
9547 be parsed in config errmsg directives [Howard Fear]
9548 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9549 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9550 4) Allow backslash-escaping to all quoted text
9551 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9552 5) Pass variable to command line if not set in XSSI's env
9555 *) Fix infinite loop when processing Content-language lines in
9556 type-map files. [Alexei Kosut]
9558 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9560 *) Fixed problem in set_[user|group] that prevented CGI execution
9561 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9563 *) Added PORTING information file. [Jim Jagielski]
9565 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9567 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9569 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9570 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9572 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9573 which caused problems of systems where socket s_addr is >32bits.
9575 *) Added comment to explain (r->chunked = 1) side-effect in
9576 http_protocol.c [Roy Fielding]
9578 *) Replaced use of index() in mod_expires.c with more appropriate
9579 and portable isdigit() test. [Ben Laurie]
9581 *) Updated Configure for ...
9582 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9583 *-dg-dgux* (bad pattern match)
9584 QNX (DEF_WANTHSREGEX=yes)
9585 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9588 and added some user diagnostic info. [Ben Laurie]
9590 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9591 for better portability. [Jim Jagielski]
9593 *) Updated helpers/GuessOS for ...
9594 SCO 5 (recognize minor releases)
9595 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9596 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9597 IRIX64 (-sgi-irix64)
9598 ULTRIX (-unknown-ultrix)
9599 SINIX (-whatever-sysv4)
9600 NCR Unix (-ncr-sysv4)
9601 and fixed something in helpers/PrintPath [Ben Laurie]
9603 Changes with Apache 1.2b1
9605 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9607 Changes with Apache 1.1.1
9609 *) Fixed bug where Cookie module would make two entries in the
9610 logfile for each access [Mark Cox]
9612 *) Fixed bug where Redirect in .htaccess files would cause memory
9613 leak. [Nathan Neulinger]
9615 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9617 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9619 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9621 Changes with Apache 1.1.0
9623 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9625 *) Bring QNX support up to date. [Ben Laurie]
9627 *) Make virtual hosts default to main server keepalive parameters.
9628 [Alexei Kosut, Ben Laurie]
9630 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9632 *) Fix missing address family for connect, also remove unreachable statement
9633 in mod_proxy. [Ben Laurie]
9635 *) mod_env now turned on by default in Configuration.tmpl.
9637 *) Bugs which were fixed:
9638 a) yet more mod_proxy bugs [Ben Laurie]
9639 b) CGI works again with inetd [Alexei Kosut]
9640 c) Leading colons were stripped from passwords [osm@interguide.com]
9641 d) Another fix to multi-method Limit problem [jk@tools.de]
9643 Changes with Apache 1.1b4
9645 *) r->bytes_sent variable restored. [Robert Thau]
9647 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9649 *) More possibly unsecure programs removed from the support directory.
9651 *) More mod_auth_msql authentication improvements.
9653 *) VirtualHosts based on Host: headers no longer conflict with the
9656 *) OS/2 compatibility enhancements. [Gary Smiley]
9658 *) POST now allowed to directory index CGI scripts.
9660 *) Actions now work with files of the default type.
9662 *) Bugs which were fixed:
9663 a) more mod_proxy bugs
9664 b) early termination of inetd requests
9665 c) compile warnings on several systems
9666 d) problems when scripts stop reading output early
9668 Changes with Apache 1.1b3
9670 *) Much of cgi-bin and all of cgi-src has been removed, due to
9671 various security holes found and that we could no longer support
9674 *) The "Set-Cookie" header is now special-cased to not merge multiple
9675 instances, since certain popular browsers can not handle multiple
9676 Set-Cookie instructions in a single header. [Paul Sutton]
9678 *) rprintf() added to buffer code, occurrences of sprintf removed.
9681 *) CONNECT method for proxy module, which means tunneling SSL should work.
9682 (No crypto needed) Also a NoCache config directive.
9684 *) Several API additions: pstrndup(), table_unset() and get_token()
9685 functions now available to modules.
9687 *) mod_imap fixups, in particular Location: headers are now complete
9690 *) New "info" module which reports on installed module set through a
9691 special URL, a la mod_status.
9693 *) "ServerPath" directive added - allows for graceful transition
9694 for Host:-header-based virtual hosts.
9696 *) Anonymous authentication module improvements.
9698 *) MSQL authentication module improvements.
9700 *) Status module design improved - output now table-based. [Ben Laurie]
9702 *) htdigest utility included for use with digest authentication
9705 *) mod_negotiation: Accept values with wildcards to be treated with
9706 less priority than those without wildcards at the same quality
9707 value. [Alexei Kosut]
9709 *) Bugs which were fixed:
9710 a) numerous mod_proxy bugs
9711 b) CGI early-termination bug [Ben Laurie]
9712 c) Keepalives not working with virtual hosts
9713 d) RefererIgnore problems
9714 e) closing fd's twice in mod_include (causing core dumps on
9715 Linux and elsewhere).
9717 Changes with Apache 1.1b2
9720 a) core dumps in mod_digest
9721 b) truncated hostnames/ip address in the logs
9722 c) relative URL's in mod_imap map files
9724 Changes with Apache 1.1b1
9726 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9728 Changes with Apache 1.0.3
9730 *) Internal redirects which occur in mod_dir.c now preserve the
9731 query portion of a request (the bit after the question mark).
9734 *) Escape active characters '<', '>' and '&' in html output in
9735 directory listings, error messages and redirection links.
9738 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9740 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9743 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9745 *) Reset timeout timer after each successful fwrite() to the network.
9746 This patch adds a reset_timeout() procedure that is called by
9747 send_fd() to reset the timeout ever time data is written to the net.
9750 *) timeout() signal handler now checks for SIGPIPE and reports
9751 lost connections in a more user friendly way. [Rob Hartill]
9753 *) Location of the "scoreboard" file which used to live in /tmp is
9754 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9755 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9757 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9759 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9760 which caused a SEGV with cookies enabled
9762 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9765 *) Log the UNIX textual error returned by some system calls, in
9766 particular errors from accept() [David Robinson]
9768 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9770 Changes with Apache 1.0.2
9772 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9773 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9775 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9778 *) past changes to http_config.c to only use the
9779 setrlimit function on systems defining RLIMIT_NOFILE
9780 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9781 for SUNOS and prototypes the needed functions.
9783 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9786 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9788 *) Merge multiple headers from CGI scripts instead of taking last
9789 one. [David Robinson]
9791 *) Add support for SCO 5. [Ben Laurie]
9793 Changes with Apache 1.0.1
9795 *) Silence mod_log_referer and mod_log_agent if not configured
9798 *) Recursive includes can occur if the client supplies PATH_INFO data
9799 and the server provider uses relative links; as file.html
9800 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9802 *) The replacement for initgroups() did not call {set,end}grent(). This
9803 had two implications: if anything else used getgrent(), then
9804 initgroups() would fail, and it was consuming a file descriptor.
9807 *) On heavily loaded servers it was possible for the scoreboard to get
9808 out of sync with reality, as a result of a race condition.
9809 The observed symptoms are far more Apaches running than should
9810 be, and heavy system loads, generally followed by catastrophic
9811 system failure. [Ben Laurie]
9813 *) Fix typo in license. [David Robinson]
9815 Changes with Apache 1.0.0 23 Nov 1995
9817 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9819 Changes with Apache 0.8.16 05 Nov 1995
9821 *) New man page for 'httpd' added to support directory [David Robinson]
9823 *) .htgroup files can have more than one line giving members for a
9824 given group (each must have the group name in front), for NCSA
9825 back-compatibility [Robert Thau]
9827 *) Mutual exclusion around accept() is on by default for SVR4 systems
9828 generally, since they generally can't handle multiple processes in
9829 accept() on the same socket. This should cure flaky behavior on
9830 a lot of those systems. [David Robinson]
9832 *) AddType, AddEncoding, and AddLanguage directives take multiple
9833 extensions on a single command line [David Robinson]
9835 *) UserDir can be disabled for a given virtual host by saying
9836 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9837 that this didn't work. [David Robinson]
9839 *) Compiles on QNX [Ben Laurie]
9841 *) Corrected parsing of ctime time format [David Robinson]
9843 *) httpd does a perror() before exiting if it can't log its pid
9844 to the PidFile, to make diagnosing the error a bit easier.
9847 *) <!--#include file="..."--> can no longer include files in the
9848 parent directory, for NCSA back-compatibility. [David Robinson]
9850 *) '~' is *not* escaped in URIs generated for directory listings
9853 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9855 *) Fixed bug involving handling URIs with escaped %-characters
9856 in redirects [David Robinson]
9858 Changes with Apache 0.8.15 14 Oct 1995
9860 *) Switched to new, simpler license
9862 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9864 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9866 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9868 *) Correctly handles internal redirects to files with names containing '%'
9871 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9873 *) Use geteuid() rather than getuid() to see if we have root privilege,
9874 so that server correctly resets privilege if run setuid root. [Andrew
9877 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9880 *) Fix relative URLs in imagemap files [Randy Terbush]
9882 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9885 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9886 entries all name the same one. [David Robinson]
9888 *) Fix directory listings with filenames containing unusual characters
9891 *) Better URI-escaping for generated URIs in directories with filenames
9892 containing unusual characters [Ben Laurie]
9894 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9896 *) Unblock alarms on error return from spawn_child() [David Robinson]
9898 *) Sample Config files have extra note for SCO users [Ben Laurie]
9900 *) Configuration has note for HP-UX users [Rob Hartill]
9902 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9904 *) Nuked bogus #define in httpd.h [David Robinson]
9906 *) Better test for whether a system has setrlimit() [David Robinson]
9908 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9910 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9913 Changes with Apache 0.8.14 19 Sep 1995
9915 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9917 *) AddDescription works (better) [Ben Laurie]
9919 *) Leaves an intelligible error diagnostic when it can't set group
9920 privileges on standalone startup [Andrew Wilson]
9922 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9923 that machine, which claims to be BSD but does not support RLIMIT.
9926 *) gcc -Wall no longer complains about an unused variable when util.c
9927 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9929 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9931 Changes with Apache 0.8.13 07 Sep 1995
9933 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9935 *) Have built-in imagemap code recognize & honor Point directive [James
9938 *) Generate cleaner directory listings in directories with a mix of
9939 long and short filenames [Rob Hartill]
9941 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9943 *) Properly default ServerName for virtual servers [Robert Thau]
9945 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9946 Paul Richards and a cast of thousands...]
9948 *) On self-identified BSD systems (we don't try to guess any more),
9949 allocate a few extra file descriptors per virtual host with setrlimit,
9950 if we can, to avoid running out. [Randy Terbush]
9952 *) Write 22-character lock file name into buffer with enough space
9953 on startup [Konstantin Olchanski]
9955 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9958 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9960 *) Suppress -Wall warning by initializing variable in negotiation code
9961 [Tobias Weingartner]
9963 Changes with Apache 0.8.12 31 Aug 1995
9965 *) Doesn't pause three seconds after including a CGI script which is
9966 too slow to die off (this is done by not even trying to kill off
9967 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9968 after the entire document has been processed). [Robert Thau]
9970 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9972 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9974 *) Allows .htaccess files to override <Directory> sections naming the
9975 same directory [David Robinson]
9977 *) Removed an efficiency hack in sub_req_lookup_uri which was
9978 causing certain extremely marginal cases (e.g., ScriptAlias of a
9979 *particular* index.html file) to fail. [David Robinson]
9981 *) Doesn't log an error when the requested URI requires
9982 authentication, but no auth header line was supplied by the
9983 client; this is a normal condition (the client doesn't no auth is
9984 needed here yet). [Robert Thau]
9986 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9988 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9990 *) RFC931 code no longer passes out name of prior clients on current
9991 requests if the current request came from a server that doesn't
9992 do RFC931. [David Robinson]
9994 *) Configuration script accepts "Module" lines with trailing whitespace.
9997 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9999 *) Cleaned up comments in mod_cgi.c [Robert Thau]
10001 Changes with Apache 0.8.11 24 Aug 1995
10003 *) Wildcard <Directory> specifications work. [Robert Thau]
10005 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
10007 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
10008 the file being requested itself, in addition to the directories leading
10009 up to it. [Robert Thau]
10011 *) Logs access failures due to symlink checks or invalid client address
10012 in the error log [Roy Fielding, Robert Thau]
10014 *) Symlink checks deal correctly with systems where lstat of
10015 "/path/to/some/link/" follows the link. [Thau, Fielding]
10017 *) Doesn't reset DirectoryIndex to 'index.html' when
10018 other directory options are set in a .htaccess file. [Robert Thau]
10020 *) Clarified init code and nuked bogus warning in mod_access.c
10021 [Florent Guillaume]
10023 *) Corrected several directives in sample srm.conf
10024 --- includes corrections to directory indexing icon-related directives
10025 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
10026 icons for encodings right, and turning on AddEncoding by default).
10029 *) Corrected descriptions of args to AddIcon and AddAlt in command table
10032 *) INSTALL & README mention "contributed modules" directory [Brian
10035 *) Fixed English in the license language... "for for" --> "for".
10038 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
10039 mod_alias.c, merging it almost completely with handling of Alias, and
10040 adding a 'notes' field to the request_rec which allows the CGI module
10041 to discover whether the Alias module has put this request through
10042 ScriptAlias (which it needs to know for back-compatibility, as the old
10043 NCSA code did not check Options ExecCGI in ScriptAlias directories).
10046 Changes with Apache 0.8.10 18 Aug 1995
10048 *) AllowOverride applies to the named directory, and not just
10049 subdirectories. [David Robinson]
10051 *) Do locking for accept() exclusion (on systems that need it)
10052 using a special file created for the purpose in /usr/tmp, and
10053 not the error log; using the error log causes real problems
10054 if it's NFS-mounted; this is known to be the cause of a whole
10055 lot of "server hang" problems with Solaris. [David Robinson;
10056 thanks to Merten Schumann for help diagnosing the problem].
10058 Changes with Apache 0.8.9 12 Aug 1995
10060 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
10062 *) Nested includes see environment variables of the including document,
10063 for NCSA bug-compatibility (some sites have standard footer includes
10064 which try to print out the last-modified date). [Eric Hagberg/Robert
10067 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
10068 URI as a CGI script, even if it would have been treated as something
10069 else if requested directly, for NCSA back-compatibility. (Note that
10070 this means that people who know the name of the script can see the
10071 code just by asking for it). [Robert Thau]
10073 *) New version of dbmmanage script included in support directory as
10076 *) Check if scoreboard file couldn't be opened, and say so, rather
10077 then going insane [David Robinson]
10079 *) POST to CGI works on A/UX [Jim Jagielski]
10081 *) AddIcon and AddAlt commands work properly [Rob Hartill]
10083 *) NCSA server push works properly --- the Arena bug compatibility
10084 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
10085 if you still want the workaround). [Rob Hartill]
10087 *) If client didn't submit any Accept-encodings, ignore encodings in
10088 content negotiation. (NB this will all have to be reworked anyway
10089 for the new HTTP draft). [Florent Guillaume]
10091 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
10093 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
10095 *) Give Redirect priority over Alias, for NCSA bug compatibility
10098 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
10099 paralleling earlier bug fix for CGI [David Robinson]
10101 *) If DBM auth is improperly configured, report a server error and don't
10104 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
10105 it seems to work well enough without it (even in a 10 hits/sec
10106 workout), and the overhead for the locking under A/UX is
10107 alarmingly high (though it is very low on other systems).
10108 [Eric Hagberg, Jim Jagielski]
10110 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
10112 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
10113 Behlendorf/Eric Hagberg]
10115 *) More improvements to default Configuration for A/UX [Jim Jagielski]
10117 *) Compiles clean on NEXT [Rob Hartill]
10119 *) Compiles clean on SGI [Robert Thau]
10121 Changes with Apache 0.8.8 08 Aug 1995
10123 *) SunOS library prototypes now never included unless explicitly
10124 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
10125 people using GNU libc on SunOS are screwed by prototypes for the
10128 (Those who wish to compile clean with gcc -Wall on a standard
10129 SunOS setup need the prototypes, and may obtain them using
10130 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
10131 with nonstandard libraries are presumably competent to make their
10134 *) Strips trailing '/' characters off both args to the Alias command,
10135 to make 'Alias /foo/ /bar/' work.
10137 Changes with Apache 0.8.7 03 Aug 1995
10139 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
10140 [reported by David Robinson]
10142 *) Compiles clean on OSF/1 [David Robinson]
10144 *) Added some of the more recent significant changes (AddLanguage stuff,
10145 experimental LogFormat support) to CHANGES file in distribution root
10148 Changes with Apache 0.8.6 02 Aug 1995
10150 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10151 (If you actually wanted a conditional GET which bypassed the cache, you
10152 couldn't get it). [Reported by Roy Fielding]
10154 *) Properly terminate headers on '304 Not Modified' replies to conditional
10155 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10156 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10158 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10160 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10161 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10162 and older versions don't set the __SUNPRO_C preprocessor variable). On
10163 all other systems, these are never used anyway. [Reported by Mark Cox].
10165 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10167 Changes with Apache 0.8.5 01 Aug 1995
10169 *) Added last-minute configurable log experiment, as optional module
10171 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10172 properly. (One-line fix to http_protocol.c).
10174 *) Work around bogus behavior when reloading from Netscape.
10175 It's Netscape's bug --- for some reason they expect a request with
10176 If-modified-since: to not function as a conditional GET if it also
10177 comes with Pragma: no-cache, which is way out of line with the HTTP
10178 spec (according to Roy Fielding, the redactor).
10180 *) Added parameter to set maximum number of server processes.
10182 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10185 *) IdentityCheck bugfix [Chuck Murcko].
10187 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10189 *) More sample config file corrections; add extension to AddType for
10190 *.asis, move AddType generic description to its proper place, and
10191 fix miscellaneous typos. [ Alexei Kosut ]
10193 *) Deleted the *other* reference to the regents from the Berkeley
10194 legal disclaimer (everyplace).
10196 *) Nuked Shambhala name from src/README; had already cleaned it out
10197 of everywhere else.
10199 Changes with Apache 0.8.4
10201 *) Changes to server-pool management parms --- renamed current
10202 StartServers to MinSpareServers, created separate StartServers
10203 parameter which means what it says, and renamed MaxServers to
10204 MaxSpareServers (though the old name still works, for NCSA 1.4
10205 back-compatibility). The old names were generally regarded as
10206 too confusing. Also altered "docs" in sample config files.
10208 *) More improvements to default config files ---
10209 sample directives (commented out) for XBitHack, BindAddress,
10210 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10211 defaults, AddTypes for send-as-is and imagemap magic types, and
10212 improvements to samples for DirectoryIndex [Alexei Kosut]
10214 *) Yet more improvements to default config files --- changes to
10215 Alexei's sample AddLanguage directives, and sample LanguagePriority
10216 [ Florent Guillaume ]
10218 *) Set config file locations properly if not set in httpd.conf
10221 *) Don't escape URIs in internal redirects multiple times; don't
10222 do that when translating PATH_INFO to PATH_TRANSLATED either.
10225 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10227 Changes with Apache 0.8.3
10229 *) Edited distribution README to *briefly* summarize installation
10230 procedures, and give a pointer to the INSTALL file in the src/
10233 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10234 recent NCSA distributions.
10236 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10237 exist for the same directory, use both and don't segfault. [Reported
10240 *) Proper makefile dependencies [David Robinson]
10242 *) Note (re)starts in error log --- reported by Rob Hartill.
10244 *) Only call no2slash() after get_path_info() has been done, to
10245 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10246 reported by Andrew Wilson, though this one is probably a real bug]
10248 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10249 dump core when Referer is not supplied. [Randy Terbush]
10251 *) Lightly edited sample config files to refer people to our documentation
10252 instead of NCSA's, and to list Rob McCool as *original* author (also
10253 deleted his old, and no doubt non-functional email address). Would be
10254 nice to have examples of new features...
10256 Changes with Apache 0.8.2 19 Jul 1995
10258 *) Added AddLanuage code [Florent Guillaume]
10260 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10262 *) All sorts of problems when MultiViews finds a directory. It would
10263 be nice if mod_dir.c was robust enough to handle that, but for now,
10264 just punt. [reported by Brian Behlendorf]
10266 *) Wait for all children on restart, to make sure that the old socket
10267 is gone and we can reopen it. [reported by Randy Terbush]
10269 *) Imagemap module is enabled in default Configuration
10271 *) RefererLog and UserAgentLog modules properly default the logfile
10274 *) Mark Cox's mod_cookies added to the distribution as an optional
10275 module (commented out in the default Configuration, and noted as
10276 an experiment, along with mod_dld). [Mark Cox]
10278 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10280 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10282 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10284 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10287 Changes with Apache 0.8.1
10289 *) New imagemap module [Randy Terbush]
10291 *) Replacement referer log module with NCSA-compatible RefererIgnore
10292 [Matthew Gray again]
10294 *) Don't mung directory listings with very long filenames.
10295 [Florent Guillaume]
10297 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10299 *) New config script. See INSTALL for info. [Robert Thau]
10301 *) Scoreboard mechanism for regulating the number of extant server
10302 processes. MaxServers and StartServers defaults are the same as
10303 for NCSA, but the meanings are slightly different. (Actually,
10304 I should probably lower the MaxServers default to 10).
10306 Before asking for a new connection, each server process checks
10307 the number of other servers which are also waiting for a
10308 connection. If there are more than MaxServers, it quietly dies
10309 off. Conversely, every second, the root, or caretaker, process
10310 looks to see how many servers are waiting for a new connection;
10311 if there are fewer than StartServers, it starts a new one. This
10312 does not depend on the number of server processes already extant.
10313 The accounting is arranged through a "scoreboard" file, named
10314 /tmp/htstatus.*, on which each process has an independent file
10315 descriptor (they need to seek without interference).
10317 The end effect is that MaxServers is the maximum number of
10318 servers on an *inactive* server machine, but more will be forked
10319 off to handle unusually heavy loads (or unusually slow clients);
10320 these will die off when they are no longer needed --- without
10321 reverting to the overhead of full forking operation. There is a
10322 hard maximum of 150 server processes compiled in, largely to
10323 avoid forking out of control and dragging the machine down.
10324 (This is arguably too high).
10326 In my server endurance tests, this mechanism did not appear to
10327 impose any significant overhead, even after I forced it to put the
10328 scoreboard file on a normal filesystem (which might have more
10329 overhead than tmpfs). [Robert Thau]
10331 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10334 *) Read .htaccess files even in directory with <Directory> section.
10335 (Former incompatibility noted on mailing list, now fixed). [Robert
10338 *) "HEAD /" gives the client a "Bad Request" error message, rather
10339 than trying to send no body *and* no headers. [Cliff Skolnick].
10341 *) Don't produce double error reports for some very obscure cases
10342 mainly involving auth configuration (the "all modules decline to
10343 handle" case which is a sure sign of a server bug in most cases,
10344 but also happens when authentication is badly misconfigured).
10347 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10348 it's *for*, and this sort of thing really shouldn't be cluttering
10349 up the Makefile). [Robert Thau]
10351 *) Incidental code cleanups in http_main.c --- stop dragging
10352 sa_client around; just declare it where used. [Robert Thau]
10354 *) Another acc-related fix. (It doesn't like const char
10355 in some places...). [Mark Cox]
10357 Changes with Shambhala 0.6.1 13 Jul 1995
10359 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10360 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10362 *) Compiles clean with acc on SunOS [Paul Sutton]
10364 *) Reordered modules in modules.c so that Redirect takes priority
10365 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10366 believe it or not, he has an actual site with a ScriptAlias and
10367 a Redirect declared for the *exact same directory*. Even *my*
10368 compatibility fetish wouldn't motivate me to fix this if the fix
10369 required any effort, but it doesn't, so what the hey.
10371 *) Fixed to properly default several server_rec fields for virtual
10372 servers from the corresponding fields in the main server_rec.
10373 [Cliff Skolnick --- 'port' was a particular irritant].
10375 *) No longer kills off nph- child processes before they are
10376 finished sending output. [Matthew Gray]
10378 Changes with Shambhala 0.6.0 10 Jul 1995
10380 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10381 the connection to the client in an "aborted" state, but otherwise
10382 allow whatever handlers are running to clean up. hard_timeout()s
10383 abort the request in progress completely; anything not tied to some
10384 resource pool cleanup will leak. They're still around because I
10385 haven't yet come up with a more elegant way of handling
10386 timeouts when talking to something that isn't the client. The
10387 default_handler and the dir_handler now use soft timeouts, largely
10388 so I can test the feature. [Robert Thau]
10390 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10391 the case of log handlers dying prematurely is probably handled VERY
10392 gracelessly at this point, and if the logger stops reading input,
10393 the server will hang. (It is known to correctly restart the
10394 logging process on server restart; this is (should be!) going through
10395 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10396 script). [Robert Thau]
10398 *) asis files supported (new module). [Robert Thau]
10400 *) IdentityCheck code is compiled in, but has not been tested. (I
10401 don't know anyone who runs identd). [Robert Thau]
10403 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10404 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10406 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10408 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10409 as timeouts are not in scope. [Robert Thau]
10411 *) quoted-string args in config files now handled correctly (doesn't drop
10412 the last character). [Robert Thau; reported by Randy Terbush]
10414 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10415 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10417 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10418 default default type); the former default default behavior when all
10419 type-checkers defaulted had been a core dump. [Paul Sutton]
10421 *) Copy filenames out of the struct dirent when indexing
10422 directories. (On Linux, readdir() returns a pointer to the same
10423 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10425 Changes with Shambhala 0.5.3 [not released]
10427 *) Default response handler notes "file not found" in the error log,
10428 if the file was not found. [Cliff Skolnick].
10430 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10431 code no longer sets up bogus PATH_INFO which fakes out the directory
10432 handler). [Cliff Skolnick]
10434 Changes with Shambhala 0.5.2 06 Jul 1995
10436 *) Changes to http_main.c --- root server no longer plays silly
10437 games with SIGCHLD, and so now detects and replaces dying
10438 children. Child processes just die on SIGTERM, without taking
10439 the whole process group with them. Potential problem --- if any
10440 child process refuses to die, we hang in restart.
10441 MaxRequestsPerChild may still not work, but it certainly works
10442 better than it did before this! [Robert Thau]
10444 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10445 work (or work better, at least); over-long description lines
10446 properly terminated. [Mark Cox]
10448 *) http_request.c now calls unescape_url() more places where it
10449 should [Paul Sutton].
10451 *) More directory handling bugs (reported by Cox)
10452 Parent Directory link is now set correctly. [Robert Thau]
10454 Changes with Shambhala 0.5.1 04 Jul 1995
10456 *) Generalized cleanup interface in alloc.c --- any function can be
10457 registered with alloc.c as a cleanup for a resource pool;
10458 tracking of files and file descriptors has been reimplemented in
10459 terms of this interface, so I can give it some sort of a test.
10462 *) More changes in alloc.c --- new cleanup_for_exec() function,
10463 which tracks down and closes all file descriptors which have been
10464 registered with the alloc.c machinery before the server exec()s a
10465 child process for CGI or <!--#exec-->. CGI children now get
10466 started with exactly three file descriptors open. Hopefully,
10467 this cures the problem Rob H. was having with overly persistent
10468 CGI connections. [Robert Thau]
10470 *) Mutual exclusion around the accept() in child_main() --- this is
10471 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10472 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10473 This uses fcntl(F_SETLK,...) on the error log descriptor because
10474 flock() on that descriptor won't work on systems which have BSD
10475 flock() semantics, including (I think) Linux 1.3 and Solaris.
10477 This does work on SunOS (when the server is idle, only one
10478 process in the pool is waiting on accept()); it *ought* to work
10479 on the other systems. [Robert Thau]
10481 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10483 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10485 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10487 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10488 be unnecessary if I go to the revised timeout-handling scheme).
10491 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10492 string) even if none came in with the request. [Robert Thau]
10494 *) CHANGES file added to distribution ;-).
10496 Changes with Shambhala 0.4.5
10498 *) mod_dld --- early dynamic loading support [rst]
10499 *) Add wildcard content handlers for XBITHACK; default_hander now
10500 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10501 *) XBITHACK supported as a wildcard content-handler, and
10502 configurable at run-time (not just at compile time, as in the
10503 "patchy server" releases) [rst]
10505 Changes with Shambhala 0.4.4 30 Jun 1995
10507 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10508 *) Handle Addtype x/y .z [rst, reported by Cox]
10510 Changes with Shambhala 0.4.3
10512 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10513 synonymous [rst, terbush]
10515 Changes with Shambhala 0.4.1 28 Jun 1995
10517 *) First-cut virtual host implementation; some refit in the config
10518 reading code, and log management, was necessary to support this [rst]
10519 *) Sub-pool machinery, originally added to avoid excessive storage
10520 allocation on listings of large directories (which turned out to
10521 be the problem that the 0.3 storage accounting was added to
10522 find). Subrequests and mod_dir changed to use subpools. [rst]
10523 *) More memory debugging --- free list consistency checks. [rst]
10524 *) Added err_headers to request_rec, with support elsewhere [rst]
10525 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10527 Changes with Shambhala 0.3 19 Jun 1995
10529 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10530 *) Don't compile in mod_ai_backcompat by default
10531 *) Switch name of server from Apache to Shambhala in Makefile
10532 *) Add some accounting routines to track memory usage in the pools,
10535 Changes with Shambhala 0.2
10537 *) Set DOCUMENT_ROOT CGI variable
10538 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10539 *) Add critical section protection to handling of cleanup structures
10541 *) Significant code reorg within the server core to group related
10542 functions together [rst]
10543 *) Correctly handle clients that hang up before sending any request
10545 *) Replace dying child processes. [rst]
10547 Changes with Shambhala 0.1 12 Jun 1995
10549 Major rewrite of the pre-existing "patchy server" codebase, by
10550 Robert Thau (rst). Significant portions of the server code, such
10551 as configuration-file handling and HTTP authentication support,
10552 were ripped out and rewritten from scratch. Code that was not
10553 completely rewritten was significantly altered.
10555 Major changes with this release include:
10557 *) Introduction of the module API; in request handling, the central
10558 machinery just dispatches to various modules, which actually do
10559 most of the work. Configuration handling is similar --- modules
10560 declare their own commands, and the central machinery just
10561 dispatches to them.
10563 API features from shambhala/0.1 were substantially unchanged in
10564 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10565 release, such as wildcard handlers and subpools, were added in
10566 subsequent Shambhala releases, and were also generally rst's
10569 *) This release included the following modules:
10571 mod_access (access control --- allow and deny directives),
10572 mod_alias (Alias and Redirect commands),
10573 mod_auth (straight HTTP authentication, based on flat-files)
10574 mod_auth_dbm (same, with dbm files)
10575 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10576 mod_common_log (CLF access logs; later renamed mod_log_common)
10577 mod_dir (directory indexing)
10578 mod_include (server-side includes)
10579 mod_mime (AddType directives)
10580 mod_negotiation (content negotiation)
10581 mod_userdir (support for users' public_html directories)
10583 It also included a mod_ai_backcompat, which was a private hack
10584 for back-compatibility with rst's own AI-lab servers.
10586 All of these modules were substantially complete, and functional
10587 or nearly so (a few, which implemented features not in use at
10588 Thau's site, required patches of a few lines).
10590 *) sub-request machinery, to allow modules to determine how other
10591 modules would assign MIME types to a given file, or optionally
10592 serve its content (this is heavily used by mod_dir, mod_include
10593 and mod_negotiation).
10595 *) Resource pool system for keeping track of memory allocated and
10596 files opened in service of a particular request. Much of the
10597 code in the modules (when they weren't rewrites) was adjusted to
10598 replace a pervasive convention of using fixed-size buffers on
10599 the stack with an equally pervasive convention of using memory
10600 allocated with palloc().
10602 *) Reorganization of data structures associated with a given
10603 request to eliminate use of global variables and the troublesome
10604 unmunge_name function (used in NCSA and early Apache releases to
10605 attempt to determine the URI which mapped to a given filename
10606 --- a difficult proposition, given that it is easy to produce
10607 setups in which multiple URIs map to the same file).
10609 *) Source files renamed and rearranged
10611 *) Very simple pre-forking behavior --- parent process forked off a
10612 fixed number of children, and then just waited for SIGHUP.
10614 *) Other more minor changes too numerous to list.
10616 This release included modified versions of a lot of code from the
10617 Apache 0.6.4 public release, plus an early pre-forking patch
10618 codeveloped by Robert Thau and Rob Hartill.
10620 Changes with Apache 0.7.3 20 Jun 1995
10622 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10623 were incorporated by Rob Hartill on the main branch while Robert Thau
10624 worked on the Shambhala rewrite above. Most were merged into the
10625 Shambala architecture after Apache 0.8.0.
10627 Changes with Apache 0.6.4 13 May 1995
10629 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10632 Changes with Apache 0.5.1 10 Apr 1995
10634 Changes with Apache 0.4 02 Apr 1995
10636 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10639 Changes with Apache 0.3 24 Mar 1995
10641 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10644 Changes with Apache 0.2 18 Mar 1995
10646 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10647 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10648 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
