1 Changes with Apache 2.0.29-dev
3 *) Allow modules that add sockets to the ap_listeners list to
4 define the function that should be used to accept on that
5 socket. Each MPM can define their own function to use for
6 the accept function with the MPM_ACCEPT_FUNC macro. This
7 also abstracts out all of the Unix accept error handling
8 logic, which has become out of synch across Unix MPMs.
11 *) Fix a bug which would cause the response headers to be omitted
12 when sending a negotiated ErrorDocument because the required
13 filters were attached to the wrong request_rec.
14 [John Sterling <sterling@covalent.net>]
16 *) Remove commas from the end of the macros that define
17 directives that are used by MPMs. Prior to this patch,
18 you would use these macros without commas, which was unlike
19 the macros for any other directives. Now, the caller provides
20 the comma rather than the macro providing it. This makes
21 the macros look more like the rest of the directives.
22 [Ryan Bloom and Cliff Woolley]
24 *) Add 'redirect-carefully' environment option to disable sending
25 redirects under special circumstances. This is helpful for
26 Microsoft's WebFolders when accessing a directory resource via
27 DAV methods. [Justin Erenkrantz]
29 *) Begin to abstract out the underlying transport layer.
30 The first step is to remove the socket from the conn_rec,
31 the server now lives in a context that is passed to the
32 core's input and output filters. This forces us to be very
33 careful when adding calls that use the socket directly,
34 because the socket isn't available in most locations.
37 *) Really reset the MaxClients value in worker and threaded
38 when the configured value is not a multiple of the number
39 of threads per child. We said we did previously but we
40 forgot to. [Jeff Trawick]
42 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
44 *) If shared modules are requested and mod_so is not available,
45 produce a fatal config-time error. [Justin Erenkrantz]
47 *) Improve http2env's performance by cutting the work it has to
48 do. [Brian Pane <bpane@pacbell.net>]
50 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
51 [Brian Pane <bpane@pacbell.net>]
53 Changes with Apache 2.0.28
55 *) Fix infinite loop in mod_cgid.c.
56 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
58 *) When no port is given in a "ServerName host" directive, the
59 server_rec->port is now set to zero, not 80. That allows for
60 run-time deduction of the correct server port (depending on
61 SSL/plain, and depending also on the current setting of
62 UseCanonicalName). This change makes redirections
63 work, even with https:// connections. As in Apache-1.3, the
64 connection's actual port number is never used, only the ServerName
65 setting or the client's Host: setting. Documentation updated
66 to reflect the change. [Martin Kraemer]
68 *) Add a '%{note-name}e' argument to mod-headers, which works in
69 the same way as mod_log_confg. [Ian Holsman]
71 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
72 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
75 *) Introduce htdbm, a user management utility for db/dbm authorization
76 databases. [Mladen Turk <mturk@mappingsoft.com>]
78 *) Optimize usage of strlen and strcat in ap_directory_walk.
79 [Brian Pane <bpane@pacbell.net>]
81 Changes with Apache 2.0.27
83 *) Introduce an Apache mod_ssl initial configuration template
84 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
86 *) Fixed a memory leak in the getline parsing code that could
87 be triggered by arbitrarily large header lines. Requests
88 from the core input filter for single lines are now limited
89 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
91 *) Fix a truncation bug in how we print the port on the Via: header.
92 The routine that prints the Via: header now takes a length for
93 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
95 *) Some syntax errors in mod_mime_magic's magic file can result
96 in a 500 error, which previously was unlogged. Now we log the
99 *) Add the support/checkgid helper app, which checks the run-time
100 validity of group identifiers usable in the Group directive.
103 *) Various --enable-so options have been fixed: --enable-so is
104 treated as "static"; explicit --enable-so=shared issues an error;
105 and explicit --enable-so fails with error on systems without
106 APR_HAS_DSO. [Aaron Bannert]
108 *) Fix a segfault in the core input filter when the client socket
109 gets disconnected unexpectedly. [Cliff Woolley]
111 *) Fix the reporting for child processes that die. This removes
112 all of the non-portable W* macros from Apache.
113 [Jeff Trawick and Ryan Bloom]
115 *) Win32: Track and display "Parent Server Generation:" in
116 mod_status output. The generation will be bumped at
117 server graceful restart, when the child process exits
118 by hitting MaxRequestsPerChild or if the child
119 process exits abnormally. [Bill Stoddard]
121 *) Win32: Fix problem where MaxRequestsPerChild directive was
122 not being picked up in favor of the default. Enable
123 the parent to start up a new child process immediately upon
124 the old child starting shutdown.
127 *) Fix some bungling of the remote port in rfc1413.c so that
128 IdentityCheck retrieves the proper user id instead of failing
129 and thus always returning "nobody."
130 [Dick Streefland <Dick.Streefland@xs4all.nl>]
132 *) Introduced thread saftey for mod_rewrite's internal cache.
133 [Brian Pane <bpane@pacbell.net>]
135 *) Simplified mod_env's directives to behave as most directives are
136 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
137 directive following that UnsetEnv within the same container.
138 Also provides a runtime startup warning if a PassEnv configured
139 environment value is undefined. [William Rowe]
141 *) The worker MPM is now completely ported to APR's new lock API. It
142 uses native APR types for thread mutexes, cross-process mutexes,
143 and condition variables. [Aaron Bannert]
145 *) Sync up documentation to remove all references to the now deprecated
146 Port directive. [Justin Erenkrantz]
148 *) Moved all ldap modules from the core to httpd-ldap sub-project
151 *) Exit when we can't listen on any of the configured ports. This
152 is the same behavior as 1.3, and it avoids having the MPMs to
153 deal with bogus ap_listen_rec structures. [Jeff Trawick]
155 *) Cleanup the proxy code that creates a request to the origin
156 server. This change adds an optional hook, which allows modules
157 to gain control while the request is created if the proxy module
158 is loaded. The purpose of this hook is to allow modules to add
159 input and/or output filters to the request to the origin. While
160 I was at it, I made the core use this hook, so that proxy request
161 creation uses some of the code from the core. This can still be
162 greatly improved, but this is a good start. [Ryan Bloom]
164 Changes with Apache 2.0.26
166 *) Port the MaxClients changes from the worker MPM to the threaded
169 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
170 with the new input filtering system. [Justin Erenkrantz]
172 *) Introduce the MultiviewsMatch directive, to allow the operator
173 to be flexible in recognizing Handlers and Filters filename
174 extensions as part of the Multiviews matching logic, strict with
175 MultiviewsMatch NegotiatedOnly to accept only filename extentions
176 that designate negotiated parameters, (content type, charset, etc.)
177 or MultiviewsAll for the 1.3 behavior of matching any files, even
178 if they have unregistered extensions. [William Rowe]
180 *) Fixed the configure script to add a LoadModule directive to
181 the default httpd.conf for any module that was compiled
182 as a DSO. [Aaron Bannert <aaron@clove.org>]
184 *) rewrite mod_ssl input filtering to work with the new input filtering
185 system. [Justin Erenkrantz]
187 *) prefork: Don't segfault when we are able to listen on some but
188 not all of the configured ports. [Jeff Trawick]
190 *) Build mod_so even if no core modules are built shared.
191 [Aaron Bannert <aaron@clove.org>]
193 *) Introduce ap_directory_walk rewrite (with further optimizations
194 required) to adapt to the ap_process_request_internal() changes.
195 Optimized so subrequests and redirects now reuse previous section
196 merges, until we mismatch with the original directory_walk, and
197 precomputed r->finfo results will cause directory_walk to skip
198 the most expensive phases of the function. [William Rowe]
200 *) Allow ApacheMonitor to connect to and control Apache on other
201 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
203 *) Remove the Port directive. In it's place, the Listen directive
204 is now a required directive, which tells Apache what port to
205 listen on. The ServerName directive has also been extended
206 to accept an optional port. If the port is specified to the
207 ServerName, the server will report that port whenever it
208 reports the port that it is listening on. This change was
209 made to ease configuration errors that stem from having a Port
210 directive, and a Listen directive. In that situation, the server
211 would only listen to the port specified by the Listen command,
212 which caused a lot of confusion to users. [Ryan Bloom]
214 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
215 build, as loadable modules. [William Rowe]
217 *) Fix --enable-mods-shared processing. If most is specified,
218 then all modules that can be compiled as shared modules are.
219 [Aaron Bannert <aaron@clove.org>]
221 *) Update the mime.types file to map video/vnd.mpegurl to mxu
222 and add commonly used audio/x-mpegurl for m3u extensions.
223 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
225 *) Eliminate the depreciated r->content_language, in favor of the array
226 r->content_languages introduced many years ago. Module authors must
227 substantially overhaul their modules, so this needs to be upgraded
228 if the module still relied on backwards-brokeness. [William Rowe]
230 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
233 *) Rewrite the input filtering mechanisms to consolidate and reorganize
234 code. In short, core_input_filter does something now and
235 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
237 *) Update the Win32 build to re-absorb mod_proxy and family.
240 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
241 current SDK.) [William Rowe]
243 *) Some style changes to the code that does ProxyErrorOverride. Fixed
244 config merge behaviour. [Graham Leggett]
246 *) Allow support programs to be compiled against a static version
247 of libapr. This allows the smaller support programs to be
248 relocated. [Aaron Bannert <aaron@clove.org>]
250 *) Update the mime.types file to the registered media types as
251 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
253 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
254 number of clients that can connect at the same time, instead of
255 specifying the maximum number of child processes.
256 [Aaron Bannert <aaron@clove.org>]
258 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
259 be consistent with 1.3. [Justin Erenkrantz]
261 *) Cache apr_explode_localtime() value for 15 seconds.
262 [Brian Pane <bpane@pacbell.net>]
264 *) Fix mod_include to not return ETag or Last-Modified headers.
265 [Ian Holsman <ianh@cnet.com>]
267 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
269 *) Eliminate the wasteful run-time conversion of method names from strings
270 to numbers in places where the methods are known at compile time.
271 [Brian Pane <bpane@pacbell.net>]
273 *) Turn the worker MPM's queue into a LIFO. This may
274 improve cache-hit performance under some conditions.
275 [Aaron Bannert <aaron@clove.org>]
277 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
278 support it. [Justin Erenkrantz]
280 *) Cleanup the worker MPM. We no longer re-use transaction
281 pools. This incurs less overhead than shuffling the pools
282 around so that they can be re-used. Remove one of the
283 queue's condition variables. We just redefined the API to
284 state that you can't try to add more stuff than you allocated
285 segments for. [Aaron Bannert <aaron@clove.org>]
287 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
289 *) Fixed persistent connections when a request contains a body.
292 *) mod_dav uses a new API to speak to the backend provider for dead
293 property management. [Greg Stein]
295 *) Remove the Win32 script-processing exception from mod_cgi, and
296 roll build_command_line/build_argv_list into a unified, overrideable
297 ap_cgi_build_command optional function. [William Rowe]
299 *) Rewrite find_start_sequence to use a better search algorithm
300 to find the start tag. [Justin Erenkrantz]
302 *) Fix a seg fault in mod_include. When we are generating an
303 internal redirect, we must set r->uri to "", not a bogus
304 string, and not NULL. [Ryan Bloom]
306 *) Optimized location_walk, so subrequests, redirects and second passes
307 now reuse previous section merges on a <Location > by <Location >
308 basis, until we mismatch with the original location_walk.
311 *) Back out the 1.45 change to util_script.c. This change made
312 us set the environment variable REQUEST_URI to the redirected
313 URI, instead of the originally requested URI.
314 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
316 *) Make mod_include do lazy evaluation of potentially expensive to
317 compute variables. [Brian Pane <bpane@pacbell.net>]
319 *) Fix logging of bytes sent for HEAD requests. %b and %B should
320 log either - or 0, before this patch, they were both logging
321 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
323 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
324 than per character. [Brian Pane <bpane@pacbell.net>]
326 *) Normalize the primary request, redirects and sub-requests to
327 run the same ap_process_request_internal for consistency in
328 robustness, behavior and security. [William Rowe]
330 *) Fix a segfault with mod_include when r->path_info is not set
331 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
333 *) Add -X functionality back. This indicates to all MPMs and any other
334 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
336 *) Some initial support for the cygwin platform [prefork only].
337 This is not to be confused with support for the WinNT/Win32
338 platform, which is the recommended configuration for native
339 Win32 users. The cygwin platform support is recommended for
340 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
342 *) Changed syntax of Set{Input|Output}Filter. The list of filters
343 must be semicolon delimited (if more than one filter is given.)
344 The Set{Input|Output}Filter directive now overrides a parent
345 container's directive (e.g. SetInputFilter in <Directory /web/foo>
346 will override any SetInputFilter directive in <Directory /web>.)
347 This new syntax is more consistent with Add{Input|Output}Filter
348 directives defined in mod_mime. Also cures a bug in prior releases
349 where the Set{Input|Output}Filter directive would corrupt the
350 global configuration if the multiple directives were nested.
353 *) Cured what's ailed mime for quite some time. If an AddSomething
354 was given in the configuration (Language, Charset, Handler or
355 Encoding) Apache would set the content type as given by AddType,
356 but refused to check the mime.types file if AddType wasn't given
357 for that specific extension. Setting the AddHandler for .html
358 without setting the AddType text/html html would cause Apache to
359 use the default content type. [William Rowe]
361 *) Added some bulletproofing to memory allocation in the LDAP cache
362 code. [Graham Leggett]
364 Changes with Apache 2.0.25
366 *) Move the installed /manual directory out of the /htdocs/ tree, so
367 that it can be kept more independently from the remaining document
368 root. The "Alias /manual ..." already allowed for easy projection
369 into existing private document trees. [Martin Kraemer]
371 *) Add specified user attributes to the environment when using
372 mod_auth_ldap. This allows you to use mod_include to embed specified
373 user attributes in a page like so:
374 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
377 *) Fix a performance problem with the worker MPM. We now create
378 transaction pools once, and re-use them for each connection.
379 [Aaron Bannert <aaron@clove.org>]
381 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
382 of a 'handler' or 'filter', so that any filename extension that does
383 not contribute to the negotiated metadata can't be served without
384 an explicit request. E.g., if the .Z extension is associated with
385 an unzip filter, the user request somefile.Z.html, mod_negotiation
386 won't serve it. It can serve somefile.Z.html when somefile.Z is
387 requested, since the .Z extension is explictly requested, if the
388 .html extension is associated with ContentType text/html.
391 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
392 and corresponding AddOutputFilter syntax, to insert one or more
393 filters by mod_mime filename extension processing.
396 *) Fix a growing connection pool in core_output_filter() for
397 keepalive requests. [Jeff Trawick]
399 *) Moved split_and_pass_pretag_buckets back to being a
400 macro at Ryans's request. Removed the return from it
401 by setting and returning a return code instead. Updated
402 the code to check the return code from the macro and
403 do the right thing. [Paul J. Reder]
405 *) Fix a segfault when a numeric value was received for Host:.
408 *) Add a function ap_remove_input_filter. This is to match
409 up with ap_remove_output_filter. [Ryan Bloom]
411 *) Clean up location_walk, so that this step performs a minimum
412 amount of redundant effort (it must be run twice, but it will no
413 longer reparse all <Location > blocks when the request uri
414 hadn't changed.) [William Rowe]
416 *) Eliminate proxy: (and all other 'special') processing from the
417 ap_directory_walk() phase. Modules that want to use special
418 walk logic should refer to the mod_proxy map_to_location example,
419 with it's proxy_walk and proxysection implementation. This makes
420 either directory_walk flavor much more legible, since that phase
421 only runs against real <Directory > blocks.
424 *) Fix a security problem in mod_include which would allow
425 an SSI document to be passed to the client unparsed.
426 [Cliff Woolley, Brian Pane]
428 *) Introduce the map_to_storage hook, which allows modules to bypass
429 the directory_walk and file_walk for non-file requests. TRACE
430 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
431 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
434 *) Add the ability for mod_include to add the INCLUDES filter
435 if the file is configured for the server-parsed handler.
436 This makes the configuration for .shtml files much easier
437 to understand, and allows mod_include to honor Apache 1.3
438 config files. Based on Doug MacEachern's patch to PHP
439 to do the same thing. [Ryan Bloom]
441 *) force OpenSSL to ignore process local-caching and to always
442 get/set/delete sessions using mod_ssl's callbacks
443 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
444 Geoff Thorpe <geoff@geoffthorpe.net>]
446 *) Make the worker MPM shutdown and restart cleanly. This also
447 cleans up some race conditions, and gets the worker using
448 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
450 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
452 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
454 *) Fix for mod_include. Ryan's patch to check error
455 codes put a return in the wrong place. Also, the
456 include handler return code wasn't being checked.
457 I don't like macros with returns, so I converted
458 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
459 [Paul J. Reder <rederpj@raleigh.ibm.com>]
461 *) fix segv in mod_mime if no AddTypes are configured
462 [John Sterling <sterling@covalent.net>]
464 *) Enable ssl client authentication at SSL_accept time
465 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
467 *) Fix a segfault in mod_include when the original request has no
468 associated filename (e.g., we're filtering the error document for
469 a bad URI). [Jeff Trawick]
471 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
473 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
474 of httpd is started and shuts down due to socket conflict. Moving the
475 call to ap_log_pid solves the problem.
477 *) Changed the late-1.3 log_config substitution %c to %X, to log the
478 status of the closed connection, as it conflicts with the far more
479 common, historical ssl logging directive %...{var}c. [William Rowe]
481 *) Added the common error/ tree to the build/install targets
482 (similar to the common icons/ tree) for the multi-language error
483 messages that Lars committed earlier. [William Rowe]
485 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
487 *) Added a default commented-out mod_ldap and mod_auth_ldap
488 configuration to httpd-std.conf and httpd-win.conf
491 *) Added documentation for mod_ldap and mod_auth_ldap.
494 *) Enabled negative caching on attribute comparisons in the LDAP cache.
495 Fixed a problem where the default cache TTL was set in milliseconds
496 not microseconds causing the cache to time out almost immediately.
499 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
500 module code to follow APR. [Graham Leggett]
502 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
503 cleaned up when the connection pool pool is cleaned up.
506 *) Fix a minor issue with Jeff Trawick's mod_include
507 patch. Without this patch, the code will just allocate
508 more bytes in get_combined_directive than are needed.
511 *) Added the LDAP authentication module mod_auth_ldap.
512 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
514 *) Added the LDAP cache and connection pooling module mod_ldap.
515 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
517 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
518 by allowing a module to disable itself if its prerequisites are not
519 met. [Justin Erenkrantz]
521 Changes with Apache 2.0.24
523 *) Fix a couple of issues in mod_include when the tag appeared at
524 offsets near 8192 in the file being parsed. [Jeff Trawick]
526 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
527 reached. [Jeff Trawick]
529 *) Numerous improvements to the Win32 build system. Introduced command line
530 builds without requiring .mak files for MSVC 6.0 and later versions.
531 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
534 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
535 reporting of uninstalled services and other error conditions, and changed the
536 default service name to Apache2. [William Rowe]
538 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
539 compatibility with existing Apache 1.3 Win32 Apache management utilites.
540 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
542 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
543 [William Rowe, Greg Ames]
545 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
546 and RemoveCharset directives. [William Rowe]
548 *) The Unix MPMs other than perchild now allow child server
549 processes to use the accept mutex when starting as root and
550 using SysV sems for the accept mutex. Previously, this
551 combination would lead to fatal errors in the child server
552 processes. perchild can't use SysV sems because of security
553 issues. [Jeff Trawick, Greg Ames]
555 *) Added Win32 revision stamp resources to all http binaries
556 (including modules/ and support/ tools.) PR7322 [William Rowe]
558 *) Fix ap_rvprintf to support more than 4K of data at one time.
559 [Cody Sherr <csherr@covalent.net>]
561 *) We have always used the obsolete/deprecated Netscape syntax
562 for our tracking cookies; now the CookieStyle directive
563 allows the Webmaster to choose the Netscape, RFC2109, or
564 RFC2965 format. The new CookieDomain directive allows the
565 setting of the cookie's Domain= attribute, too. PR #s 5006,
566 5023, 5920, 6140 [Ken Coar]
568 *) Tweak server/Makefile so that the rules for generating exports.c
569 are compatible with make utilities which don't expand wildcards
570 in a dependency list (e.g., OS/390 make, certain levels of GNU
571 make). [Jeff Trawick]
573 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
575 *) Begin to sanitize the MPM configuration directives. Now, all
576 MPMs use the same functions for all common MPM directives. This
577 should make it easier to catch all bugs in these directives once.
578 [Cody Sherr <csherr@covalent.net>]
580 *) Close a major resource leak. Every time we had issued a
581 graceful restart, we leaked a socket descriptor.
584 *) Fix a problem with the new method code. We need to cast
585 the 1 to an apr_int64_t or it will be treated as a 32-bit
586 integer, and it will wrap after being shifted 32 times.
587 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
589 *) Fix a bug in mod_expires. Previous to this patch, if you
590 told mod_expires to add 604800 seconds to the last-modified
591 time, it actually added 604800 usec's to the last-modified time,
592 so that when looking at the response it looked like nothing
593 had been done. The root of the problem was that we always compute
594 time in usec's, but we ask users to input sec's. This means we
595 need to convert to usec's before using those values.
598 *) The worker MPM now handles shutdown and restart requests. It
599 definitely isn't perfect, but we do stop the servers correctly.
600 The biggest problem right now is that SIGHUP causes the server to
601 just die. [Ryan Bloom]
603 Changes with Apache 2.0.23
605 *) Use the prefork MPM by default on Unix. [various]
607 *) Added a systray icon monitor application for Win32.
608 [Mladen Turk <mturk@mappingsoft.com>]
610 *) mod_rewrite: Fix the line ending on some non-Unix systems for
611 messages written to the rewrite log.
612 [Richard Labennett <rlabenn@us.ibm.com>]
614 *) All mod_autoindex query parsing is now quietly quashed with the
615 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
616 still drops the column sort <a href>'s for the column headers, but
617 IgnoreClient is required to ignore these Query options entirely.
620 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
621 to allow the client to select plain, FancyIndexing or HTMLTable
622 formatting, V=[0|1] to inhibit or enable version sorting, and
623 P=pattern to return only specific files. The old Query Arguments
624 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
625 as before), and O=A|D for ordering ascending or descending.
628 *) Fixed an error in mod_include's directive parsing routines which
629 caused #if, #elif, and #else expressions containing backslashes
630 to be improperly evaluated. [Cliff Woolley]
632 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
633 drop the icon column, SuppressRules to drop the <hr> elements,
634 and HTMLTable to create rudimentary HTML table listings (implies
635 FancyIndexing). [William Rowe]
637 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
638 from Apache 1.3.15. This is needed for two reasons, first, given
639 multiple machines within a server farm, ETags and Last-Modified
640 stamps won't correspond from machine to machine, and second, many
641 Unixes don't capture changes to the date or time stamp of existing
642 files, since these don't modify the dirent itself. [William Rowe]
644 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
645 and DirectoryWidth options from Apache 1.3.10.
646 [William Rowe, Ken Coar]
648 *) Eliminated FancyIndexing directive, deprecated early in Apache
649 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
651 *) mod_autoindex now excludes any file names that would result in
652 an error, other than a success or redirect. Also optimized
653 the parent directory, always included except in the URI '/'.
656 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
657 negotiated index pages, and prevent the server from defaulting
658 to an autoindex of the directory. mod_negotiation will now die
659 with a 500 Internal Error if it could match some filenames
660 (e.g. for mod_dir) but none can be served. mod_negotation now
661 refuses to serve any file with an extention that mod_mime doesn't
662 recognize, and wasn't part of the request. [William Rowe]
664 *) Eliminate mod_cgi's handling of .exe files without the .exe file
665 extension. This is already handled by multiviews, if the admin
666 wishes to AddHandler .exe or define a content type handler and
667 associate .exe files with that content type. Multiviews must be
668 enabled to allow these to be served. [William Rowe]
670 *) Speed up the server's response to a spike in incoming workload
671 or restarts by assigning empty scoreboard slots to new processes
672 when they are available. [Greg Ames]
674 *) Add a handler to mod_includes.c. This handler is designed to
675 implement the XbitHack directive. This can't be done with a
676 fixup, because we need to check the content-type, which is
677 only available in the handler phase. [Ryan Bloom]
679 *) Make the includes filter check return codes from filters lower in
680 the filter chain. If a lower level filter returns an error, then
681 the request needs to stop immediately. This allows mod_include to
682 stop parsing data once a lower filter recognizes an error.
685 *) Add the ability to extend the methods that Apache understands
686 and have those methods <limit>able in the httpd.conf. It uses
687 the same bit mask/shifted offset as the original HTTP methods
688 such as M_GET or M_POST, but expands the total bits from an int to
689 an ap_int64_t to handle more bits for new request methods than
690 an int provides. [Cody Sherr <csherr@covalent.net>]
692 *) Fix broken mod_mime behavior in merging its arguments. Possible
693 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
695 *) Solve many mod_ssl porting issues (too many to detail) with
696 help from the whole team, but most notably [Ralf S. Engelschall,
697 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
698 Doug MacEachern, William Rowe, Cliff Woolley]
700 *) More stall fixes for the threaded & worker mpm's.
701 Make mod_status output more accurate. Don't
702 count workers in processes which aren't actively
703 serving requests. [Greg Ames]
705 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
707 *) Add a single listener/multiple worker MPM. This MPM is
708 definately not fully correct, but it allows us to solve many
709 of the problems that exist in the threaded MPM. This is a
710 modified version of the threaded MPM. [Ryan Bloom]
712 *) Improve content generation throughout Apache, providing closer
713 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
714 Transitional specifications. [William Rowe]
716 Changes with Apache 2.0.22
718 *) Fix a problem where the threaded MPM stalls after restarts or
719 segfaults. Also prevent multiple active processes from using
720 the same scoreboard slot. [Greg Ames]
722 *) Apache/Win32 now fills in the service description with Apache's
723 server version string, including loaded and advertised modules.
726 *) Improved support for the Win32 build, to recover gracefully from
727 missing apr or apr-util directories or the awk interpreter,
728 create the proper cgi-bin examples, including a test-cgi.bat, and
729 fix the perl shebang line for printenv.pl, when installing from
730 the build environment. [William Rowe]
732 *) Fix a segfault in threaded.c caused by passing uninitialized
733 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
735 *) Use new APR number conversion functions to reduce CPU consumption
736 when setting the content length, and in mod_log_config.
739 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
740 where HEAD response headers were being repeated twice for
741 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
742 problem in the http_header filter was exposed by the recent rewrite
743 of the content_length filter. [Taketo Kabe, Bill Stoddard]
745 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
746 restarts. A garbage pointer to a vhost's server_rec from the
747 previous generation was being left around under certain
748 conditions. [Greg Ames]
750 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
751 used to appear as '(none', without the closing paren.
752 [Günter Knauf <eflash@gmx.net>]
754 *) Improve the exports generating awk script. In the past, we had
755 work around problems in the awk script by avoiding some #if and
756 #ifdefs. This has bitten us many times in generating the exports.c
757 file. This improvement allows corrects the header file parsing.
758 [Sander Striker <striker@apache.org>]
760 Changes with Apache 2.0.21
762 *) Resolve the Win32 htpasswd bug, where a file that existed would be
763 overwritten, regardless of the -c flag.
764 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
766 *) Introduce connection sub-pools into ab. Truncating the lifetime
767 of these allocations means that ab no longer perpetually grows
768 its working set, running out of memory on large request attempts.
771 *) Make scoreboard creation a hook. This allows management
772 modules to have access to the scoreboard at the time that it is
773 created, and at every restart request.
774 [Cody Sherr <csherr@covalent.net>]
776 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
777 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
778 daemon index actually used in the scoreboard. I also
779 updated the pertinent calls. [Paul J. Reder]
781 *) Win32: Prevent listening sockets from being inherited by
782 the Apache child process, CGI scripts, rotatelog process
783 etc. If the Apache child process segfaults, any processes
784 that the child started are not reaped. Prior to this fix,
785 these processes inherited the listening sockets which sometimes
786 prevented the restarted Apache child process from accepting
787 connections (ie, the server would hang).
790 *) Provide vhost and request strings when ExtendedStatus is on.
793 *) Fix some issues with the pod and prefork: check the pod *after*
794 processing a connection so that a server processing a time-
795 consuming request bails out as soon as practical; when the
796 parent process wakes up a server process via connect(), use an
797 APR timeout on the connect() so that we don't hang for a long
798 time if there aren't server processes around to do accept().
799 [Jeff Trawick, Greg Ames]
801 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
802 spends a lot of time in apr_table_get calls. Using the default
803 httpd.conf, the tables for languages and charsets are somewhat
804 large, so the time spent scanning them on each request is
805 significant. Replacing the tables with hash tables provides
806 a nice speedup. [Brian Pane <bpane@pacbell.net>]
808 *) Add two functions to allow modules to access random parts of the
809 scoreboard. This allows modules compiled for one MPM to access the
810 scoreboard, even if it the server was compiled for another MPM.
811 [Harrie Hazewinkel <harrie@covalent.net>]
813 Changes with Apache 2.0.20
815 *) Fix problem in content-length filter where the filter would
816 buffer all the output from a CGI before sending any bytes
817 down the filter stack to the network. This problem would cause
818 significant memory consumption if the CGIs generated
819 lots of bytes. [Bill Stoddard]
821 *) Get non-blocking CGI pipe reads working with the bucket brigades.
824 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
827 *) Fix a bug in the threaded MPM that would cause it to kill off all
828 workers immediately after starting if the number of workers started
829 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
831 Changes with Apache 2.0.19
833 *) Fix problem with threaded MPM. The problem was that if each child
834 process was busy serving a single long-lived request and the server
835 was sent a graceful restart signal, the server would stop serving
836 requests. This would happen because each child process would wait to
837 die until the last thread was done, and the parent wouldn't spawn any
838 new children until a process died. Now, the parent looks at the fact
839 that the children are dying gracefully, and starts new children.
840 Those new children only start enough threads to compliment the number
841 of threads in the other child process that shares the same spot in
842 the scoreboard. In this way, we make sure to never go over
843 MaxClients. [Ryan Bloom]
845 *) modified mod_negotiation and mod_autoindex to speed up by almost a
846 factor of two on apr_dir_read()-enhanced platforms, such as Win32
847 and OS2, by calling ap_sub_request_lookup_dirent() with the results
848 already provided by apr_dir_read(). [William Rowe]
850 *) mod_file_cache is now more robust to filtering and serves requests
851 slightly more efficiently. [Cliff Woolley]
853 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
854 Module was calling ap_rwrite() followed by ap_rflush() but the
855 served content was not being displayed in the browser. Inspection
856 of the output stream revealed that the first data chunk was
857 missing the trailing CRLF required by the RFC. [Bill Stoddard]
859 *) apxs no longer generates ap_send_http_header() in the example handler
861 *) Fix an ab problem which could cause a divide-by-zero exception
862 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
863 [Ian Holsman <ianh@cnet.com>]
865 *) Solve case-insensitive platforms' confusion about negotiated
866 filenames, allowing files of differnt case to match in choosing
867 the document to serve. [William Rowe]
869 *) Fix brokenness when ThreadsPerChild is higher than the built-in
870 limit. We left ap_threads_per_child at the higher value which
871 led to segfaults when doing certain scoreboard operations.
874 *) Fix seg faults and/or missing output from mod_include. The
875 default_handler was using the subrequest pool for files and
876 MMAPs, even though the associated APR structures typically
877 live longer than the subrequest. [Greg Ames]
879 *) Extend mod_setenvif to support specifying regular expressions
880 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
881 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
882 will cause HAVE_TS to be set if any of the request headers begins
883 with "TS" and has a value that begins with any character in the
884 set [a-z]. [Bill Stoddard]
886 *) httpd children now re-bind themselves to a random CPU on
887 multiprocessor systems on AIX via bindprocessor() in 2.0.
888 [Victor J. Orlikowski]
890 *) Fix htdigest. It would go into a loop in getline when adding
891 a second user. [Bill Stoddard]
893 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
895 *) Automatically generate httpd.exp for AIX.
896 DSOs now work again on AIX in 2.0
897 [Victor J. Orlikowski]
899 *) Add a new request hook, error_log. This phase allows modules
900 to act on the error log string _after_ it has been written
901 to the error log. The goal for this hook is to allow monitoring
902 modules to send the error string to the monitoring agent.
905 *) Modify mod_echo to make it use filters for input and output.
906 [Ryan Morgan <rmorgan@covalent.net>]
908 *) Extend mod_headers to support conditional driven Header
909 add, append and set. Use SetEnvIf to set an envar and conditionally
910 add/append/set headers based on this envar thusly:
912 SetEnvIf TSMyHeader value HAVE_TSMyHeader
913 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
915 If the request contains header "TSMyHeader: value" then header
916 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
919 *) Extend mod_headers to support using format specifiers on Header
920 add, append and set header values. Two format specifiers are supported:
922 %t - reports, in UTC microseconds since the epoch, when the
923 request was received.
925 %D - reports the time, in microseconds, between when the request was
926 received and the response sent.
929 Header add MyHeader "This request served in %D microseconds. %t"
931 results in a header being added to the response that looks like this:
933 MyHeader: This request served in D=5438 microseconds. t=991424704447256
937 *) Fix reset_filter(). We need to be careful how we remove filters.
938 If we set r->output_filters to NULL, we also have to reset the
939 connection's filters. [John Sterling]
941 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
943 *) Add a check to ap_die() to make sure the filter stack is sane and
944 contains the correct basic filters when an error occurs. This fixes
945 a problem where headers are not being sent on error. [John Sterling]
947 *) New Header directive 'echo' option. "Header echo regex" will
948 cause any headers received on the request that match regex to be
949 echoed to (included in) the response headers.
952 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
953 This prevented the inclusion of apr_compat.h. PR #7773
954 [Oleg Broytmann <phd@phd.pp.ru>]
956 *) Moved util_uri to the apr-util library. This required a bunch of
957 apr_name changes for the uri utility functions. [Justin Erenkrantz]
959 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
960 insert_filter phase so that other filters are not bypassed by default.
963 *) Reimplement mod_headers as an output filter. mod_headers can now
964 add custom headers to inbound requests using the RequestHeader directive
965 and to responses using the same old Header directive. [Graham Leggett]
967 Changes with Apache 2.0.18
969 *) Fix command-line processing so that if a bad argument is specified
970 Apache will exit. [Jeff Trawick]
972 *) Change the make targets and rules to be consistent in all of the
973 Apache-owned source trees. [Roy Fielding]
975 *) Fix processing of the TRACE method. Previously we passed bogus
976 parms to form_header_field() and it overlaid some vhost structures,
977 resulting in a segfault in check_hostalias().
978 [Greg Ames, Jeff Trawick]
980 *) Win32: Add support for reliable piped logs. If the logging process
981 goes down, Apache will automatically restart it. This function has
982 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
985 *) Do not start piped log processes during the config file
986 preflight. This change also circumvents a problem on
987 Windows where the rotatelog processes created during preflight
988 was not getting cleaned up properly.
991 *) add "Request Phase Participation" info to mod_info
994 *) Make first phase changes to the scoreboard data structures in
995 preparation for the rewriting of the scoreboard per my posted
996 design notes. [Paul J. Reder]
998 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
999 and apr-util, allow it to be overridden by the configure command-line
1000 (default="--silent") and introduce LT_LDFLAGS to replace what we were
1001 formerly abusing as LTFLAGS. [Roy Fielding]
1003 *) Clean up the reporting of incorrect closing container tags.
1004 [Barrie Slaymaker <barries@slaysys.com>]
1006 *) Simplify the configure process by moving all libtool stuff to APR
1007 and moving hints.m4 inline. [Roy Fielding]
1009 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
1010 of functions used by mod_proxy for export in the DLL
1011 [Ian Holsman <IanH@cnet.com>]
1013 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
1014 request body from its stdin but no reqest body is being written to
1015 the cgi. [Jeff Trawick]
1017 *) mod_log_config: %c connection status incorrectly logged
1018 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
1021 *) Get mod_cern_meta working under Windows
1024 *) Create Files, and thus MMAPs, out of the request pool, not the
1025 connection pool. This solves a small resource leak that had us
1026 not closing files until a connection was closed. In order to do
1027 this, at the end of the core_output_filter, we loop through the
1028 brigade and convert any data we have into a single HEAP bucket
1029 that we know will survive clearing the request_rec.
1030 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
1033 *) Completely revamp configure so that it preserves the standard make
1034 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
1035 the configure additions to EXTRA_* variables. Also, allow the user
1036 to specify NOTEST_* values for all of the above, which eliminates the
1037 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
1038 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1039 avoid pointless duplications. Fix the order in which flags are given
1040 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1041 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1042 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1043 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1045 *) Get mod_tls to compile/work better on Windows. PR #7612
1046 [Bernhard Schrenk <b.schrenk@improx.com>]
1048 *) Fix shutdown/restart hangs in the threaded MPM.
1049 [Jeff Trawick, Greg Ames, Ryan Bloom]
1051 *) Removed the keptalive boolean from conn_rec because it is now only
1052 used by a single routine and can be replaced by a local variable.
1053 [Greg Stein, Ryan Bloom, Roy Fielding]
1055 *) Patch prefork to put enough of the signal processing back in so that
1056 signals are all handled properly now. The previous patch fixed the
1057 deadlock race condition, but broke the user directed signal handling.
1058 This fixes it to work the way it did before my previous prefork patch
1059 (primarily, SIGTERM is now working).
1061 *) Change how input filters decide how much data is returned to the
1062 higher filter. We used to use a field in the conn_rec, with this
1063 change, we use an argument to ap_get_brigade to determine how much
1064 data is retrieved. [Ryan Bloom]
1066 *) Fix seg fault at start-up introduced by Ryan's change to enable
1067 modules to specify their own logging tags. mod_log_config
1068 registers an optional function, ap_register_log_handler().
1069 ap_register_log_handler() was being called by http_core before
1070 the directive hash table was created. This patch creates the
1071 directive hash table before ap_register_log_handler() is
1072 registered as an optional function.
1073 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1075 *) Add ap_set_int_slot() function
1076 [John K. Sterling <sterling@covalent.net>]
1078 *) Under certain circumstances, Apache did not supply the
1079 right response headers when requiring authentication.
1080 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1081 (This is a port of the change that went into Apache 1.3.19.)
1083 *) Allow modules to specify their own logging tags. This basically
1084 allows a module to tell mod_log_config that when %x is encountered
1085 a specific function should be called. Currently, x can be any single
1086 character. It may be more useful to make this a string at some point.
1089 Changes with Apache 2.0.17
1091 *) If a higher-level filter handles the the byterange aspects of a
1092 request, then the byterange filter should not try to redo the
1093 work. The most common case of this happening, is a byterange
1094 request going through the proxy, and the origin server handles
1095 the byterange request. The proxy should ignore it.
1096 [Graham Leggett <minfrin@sharp.fm>]
1098 *) Changed the threaded mpm to have child_main join to each of the
1099 worker threads to make sure the kids are all gone before child_main
1100 exits after a signal (cleanup from perform_idle_server_maintenance).
1101 This is an extension of Ryans recent commit to make the child_main
1104 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1105 report if their threads are dynamic or static. Finally, this also
1106 implements a new API, ap_show_mpm, which returns the MPM that was
1107 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1109 *) Do not install the binaries from the support directory twice.
1110 [jun-ichiro hagino <itojun@iijlab.net>]
1112 *) The ap_f* functions should flush data to the filter that is passed
1113 in, not the the filter after the one passed in.
1114 [Ryan Morgan <rmorgan@covalent.net>]
1116 *) Make ab work again by changing its native types to apr types and formats.
1117 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1119 *) Move the byterange filter and all of the supporting functions back
1120 to the HTTP module. The byterange filter turned out to be very
1121 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1123 *) Make clean, distclean, and extraclean consistently according to the
1124 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1126 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1127 This may have been causing problems stopping processes in the threaded
1130 *) Fix content-length in mod_negotiation to a long int representation.
1133 *) Remove BindAddress from the default config file.
1134 [giles@nemeton.com.au]
1136 *) Allow module authors to add a module to their Apache build using
1137 --with-module, without re-running buildconf. The syntax is:
1138 --with-module=module_type:/path/to/module.c
1139 The configure script will copy the module.c file to
1140 modules/module_type, and it will be added to the relevant Makefiles.
1141 currently, this only works for static modules. [Ryan Bloom]
1143 *) Changes required to make prefork clean up idle children properly.
1144 There was a window during which a starting worker deadlocks when
1145 an idle cleanup arrives before it completes init. Apache then keeps
1146 trying to cleanup the same deadlocked worker forever (until higher
1147 pids come along, but it still will never reduce below the deadlocked
1148 pid). Thus the number of children would not reduce to the correct
1149 idle level. [Paul J. Reder]
1151 Changes with Apache 2.0.16
1153 *) Change the default installation directory to /usr/local/apache2,
1154 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1156 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1159 *) Get MaxRequestsPerChild working with the Windows MPM.
1162 *) Make generic hooks to work, with mod_generic_hook_import/export
1163 experimental modules. [Ben Laurie, Will Rowe]
1165 *) Fix segfaults for configuration file syntax errors such as
1166 "<Directory>" followed by "</Directory" and
1167 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1169 *) Cleanup the --enable-layout option of configure. This makes
1170 us use a consistent location for the config.layout file, and it
1171 makes configure more portable.
1172 [jun-ichiro hagino <itojun@iijlab.net>]
1174 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1175 csv/gnuplot format, rudimentary ssl support and various other tweaks
1176 to make results more true to what is measured. The upshot of this it
1177 turns out that 'ab' has often underreported the true performance of
1178 apache. Often by a order of magnitude :-) See talk/paper of Sander
1179 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1180 [Dirk-Willem van Gulik]
1182 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1183 storage leak this ensures that some unnecessary pipes are closed.
1186 *) Performance: Add quick_handler hook. This hook is called at the
1187 very beginning of the request processing before location_walk,
1188 translate_name, etc. This hook is useful for URI keyed content
1189 caches like Mike Abbott's Quick Shortcut Cache.
1192 *) top_module global variable renamed to ap_top_module [Perl]
1194 *) Move ap_set_last_modified to the core. This is a potentially
1195 controversial change, because this is kind of HTTP specific. However
1196 many protocols should be able to take advantage of this kind of
1197 information. I expect that headers will need one more layer of
1198 indirection for multi-protocol work, but this is a small step in
1199 the right direction. [Ryan Bloom]
1201 *) Enable mod_status by default. This matches what Apache 1.3 does.
1204 *) Add a ScriptSock directive to the default config file. This is
1205 only enabled when mod_cgid is used.
1206 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1208 Changes with Apache 2.0.15
1210 *) Untangled the buildconf script and eliminated the need for build's
1211 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1212 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1214 *) Win32: Don't accept more connections than we have worker threads
1218 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1219 to fork() new child processes.
1222 *) Fix a major security problem with double-reverse lookup checking.
1223 Previously, a client connecting over IPv4 would not be matched
1224 properly when the server had an IPv6 listening socket. PR #7407
1225 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1227 *) Change the way the beos MPM handles polling to allow it to stop and
1228 restart. Problem was the sockets being polled were being reset by
1229 the select call, so once it had accepted a connection it was no
1230 longer listening on the UDP socket we use for shutdown instructions.
1231 APR needs to be altered, patch on it's way. [David Reid]
1233 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1234 on error exit from ap_getline(). Some other code got upset because
1235 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1237 *) Handle ap_discard_request_body() being called more than once.
1238 [Greg Ames, Jeff Trawick]
1240 *) Get rid of an inadvertent close of file descriptor 2 in
1241 mod_mime_magic. [Greg Ames, Jeff Trawick]
1243 *) Add a hook, create_request. This hook allows modules to modify
1244 a request while it is being created. This hook is called for all
1245 request_rec's, main request, sub request, and internal redirect.
1246 When this hook is called, the the r->main, r->prev, r->next
1247 pointers have been set, so modules can determine what kind of
1248 request this is. [Ryan Bloom]
1250 *) Cleanup the build process a bit more. The Apache configure
1251 script no longer creates its own helper scripts, it just
1253 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1255 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1256 proxy requests. [Graham Leggett]
1258 *) Avoid using sscanf to determine the HTTP protocol number in
1259 the common case because sscanf is a performance hog. From
1260 Mike Abbot's Accelerating Apache patch number 6.
1261 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1263 *) Fix a security exposure in mod_access. Previously when IPv6
1264 listening sockets were used, allow/deny-from-IPv4-address rules
1265 were not evaluated properly (PR #7407). Also, add the ability to
1266 specify IPv6 address strings with optional prefix length on Allow
1267 and Deny. [Jeff Trawick]
1269 *) Enhance rotatelogs so that a UTC offset can be specified, and
1270 the logfile name can be formatted using strftime(3). (Brought
1271 forward from 1.3.) [Ken Coar]
1273 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1274 DuplicateHandle on an IOCompletionPort (a practice which
1275 MS "discourages"). The new model does not rely on associating
1276 the completion port with the listening sockets, thus the
1277 completion port can be completely managed within the child
1278 process. A dedicated thread accepts connections off the network,
1279 then calls PostQueuedCompletionStatus() to wake up worker
1280 threads blocked on the completion port.
1283 *) Bring forward the --suexec-umask option which allows the
1284 builder to preset the umask for suexec processes. [Ken Coar]
1286 *) Add a -V flag to suexec, which causes it to display the
1287 compile-time settings with which it was built. (Only
1288 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1290 *) Mod_include should always unset the content-length if the file is
1291 going to be passed through send_parsed_content. There is no to
1292 determine if the content will change before actually scanning the
1293 entire content. It is far safer to just remove the C-L as long
1294 as we are scanning it. [Ryan Bloom]
1296 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1297 request and not Proxy-Authenticate.
1298 [Graham Leggett <minfrin@sharp.fm>]
1300 Changes with Apache 2.0.14
1302 *) Fix content-length computation. We ONLY compute a content-length if
1303 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1304 or we already have all the data. [Ryan Bloom]
1306 *) Report unbounded containers in the config file. Previously, a typo
1307 in the </container> directive could result in the rest of the config
1308 file being silently ignored, with undesired defaults used.
1311 *) Make the old_write filter use the ap_f* functions for the buffering.
1314 *) Move more code from the http module into the core server. This
1315 is core code, basically the default handler, the default input
1316 and output filters, and all of the core configuration directives.
1317 All of this code is required in order for the server to work, with or
1318 without HTTP. The server is closer to working without the HTTP
1319 module, although there is still more to do. [Ryan Bloom]
1321 *) Fix a number of SGI compile warnings throughout the server. Fix some
1322 bad parameters to apr_bucket_read(). Fix a bad statement in
1323 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1324 consistently; we were mixing apr_time_t and time_t in invalid ways
1325 before. In load_file(), call apr_dso_error() instead of
1326 apr_strerror() so that we get a more specific string on some platforms.
1327 PR #6980 [Jeff Trawick]
1329 *) Allow modules to query the MPM about it's execution profile. This
1330 query API can and should be extended in the future, but for now,
1331 max_daemons, and threading or forking is a very good start.
1332 [Jon Travis <jtravis@covalent.net>]
1334 *) Modify mod_include to send blocks of data no larger than 9k.
1335 Without this, mod_include will wait until the whole file is parsed,
1336 or the first tag is found to send any data to the client.
1337 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1339 *) Fix mod_info, so that <Directory> and <Location> directives are
1340 not displayed twice when displaying the current configuration.
1341 [Ryan Morgan <rmorgan@covalent.net>]
1343 *) Add config directives to override DEFAULT_ERROR_MSG and
1344 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1345 [Dan Rench <drench@xnet.com>]
1347 *) Get mod_info building and loading on Win32. [William Rowe]
1349 *) Begin to move protocol independant functions out of mod_http. The goal
1350 is to have only functions that are HTTP specific in the http directory.
1353 Changes with Apache 2.0.13
1355 *) Don't assume that there will always be multiple calls to the byterange
1356 filter. It is possible that we will need to do byteranges with only
1357 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1359 *) Move the error_bucket definition from the http module to the
1360 core server. Every protocol will need this ability, not just
1363 Changes with Apache 2.0.12
1365 *) Modify mod_file_cache to save pre-formatted strings for
1366 content-length and last-modified headers for performance.
1367 [Mike Abbot <mja@trudge.engr.sgi.com>]
1369 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1370 [Jon Travis <jtravis@covalent.net>]
1372 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1373 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1375 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1376 without ever filling it out. This fixes PR 7271.
1377 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1378 Cliff Woolley <cliffwoolley@yahoo.com>]
1380 *) Add a couple of GCC attribute tags to printf style functions.
1381 [Jon Travis <jtravis@covalent.net>]
1383 *) Add the correct language tag for interoperation with the Taiwanese
1384 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1386 *) Migrate the perchild MPM to use the new apr signal child, and
1387 APR thread functions. [Ryan Bloom]
1389 *) Close one copy of the CGI's stdout before creating the new process.
1390 The CGI will still have stdout, because we have already dup'ed it.
1391 This keeps Apache from waiting forever to send the results of a CGI
1392 process that has forked a long-lived child process.
1393 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1395 *) Remove the rest of the pthreads functions from the threaded MPM.
1396 This requires the APR support for a signal thread that was just
1399 *) Make mod_dir use a fixup for sending a redirect to the browser.
1400 Before this, we were using a handler, which doesn't make much
1401 sense, because the handler wasn't generating any data, it would
1402 either return a redirect error code, or DECLINED. This fits the
1403 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1405 *) Make the threaded MPM use APR threads instead of pthreads.
1408 *) Get mod_tls to the point where it actually appears to work in all cases.
1411 *) implement --enable-modules and --enable-mods-shared for "all" and
1412 "most". [Greg Stein]
1414 *) Move the threaded MPM to use APR locks instead of pthread locks.
1417 *) Rename mpmt_pthread to threaded. This is more in line with the
1418 fact that mpmt_pthread shouldn't be using pthreads directly, and
1419 it is a smaller name that doesn't tie into anything.
1422 *) Rename the module structures so that the exported symbol matches
1423 the file name, and it is easier to automate the installation
1424 process (generating LoadModule directives from the module filenames).
1427 *) Remove the coalesce filter. With the ap_f* functions, this filter
1428 is no longer needed. [Ryan Bloom]
1430 Changes with Apache 2.0.11
1432 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1433 added feature of allowing a uid/gid per child process. If no
1434 uid/gid is specified, then Perchild behaves exactly like dexter.
1437 *) Get perchild building again. [Ryan Bloom]
1439 *) Don't disable threads just because we are using the prefork MPM.
1440 If somebody wants to compile without threads, they must now add
1441 --disable-threads to the configure command line. [Ryan Bloom]
1443 *) Begin to move the calls to update_child_status into common code, so
1444 that each individual MPM does not need to update the scoreboard itself.
1447 *) Allow mod_tls to compile under Unix boxes where openssl has been
1448 installed to the system include files.
1449 [Gomez Henri <new-httpd@slib.fr>]
1451 *) Cleanup the mod_tls configure process. This should remove any need
1452 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1453 configure doesn't check that yet. [Ryan Bloom]
1455 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1456 vital that you read modules/tls/README before attempting to build
1459 *) Fix a potential seg fault on all platforms. David Reid fixed this
1460 on BEOS, but the problem could happen anywhere, so we don't want
1461 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1463 *) Add new LogFormat directive, %D, to log time it takes to serve a
1464 request in microseconds. [Bill Stoddard]
1466 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1467 SetOutputFilter. This corresponds nicely with the other Set
1468 directives, which operate on containers while the Add* directives
1469 tend to work directly on extensions. [Ryan Bloom]
1471 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1472 functions for the buffering so that we don't need to compute
1473 the length of the headers before we actually create the header
1474 buffer. [Ryan Bloom]
1476 *) Allow filters to buffer data using the ap_f* functions. These have
1477 become macros that resolve directly to apr_brigade_*.
1480 *) Get the Unix MPM's to do a graceful restart again. If we are going
1481 to register a cleanup with ap_cleanup_scoreboard, then we have to
1482 kill the cleanup with the same function, and that function can't be
1483 static. [Ryan Bloom]
1485 *) Install all required header files. Without these, it was not
1486 possible to compile some modules outside of the server.
1489 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1490 forward from 1.3 to 2.0, we missed a single line, which broke regex
1491 aliases. [Ryan Bloom]
1493 *) We have a poor abstraction in the protocol. This is a temporary
1494 hack to fix the bug, but it will need to be fixed for real. If
1495 we find an error while sending out a custom error response, we back
1496 up to the first non-OK request and send the data. Then, when we send
1497 the EOS from finalize_request_protocol, we go to the last request,
1498 to ensure that we aren't sending an EOS to a request that has already
1499 received one. Because the data is sent on a different request than
1500 the EOS, the error text never gets sent down the filter stack. This
1501 fixes the problem by finding the last request, and sending the data
1502 with that request. [Ryan Bloom]
1504 *) Make the server status page show the correct restart time, and
1505 thus the proper uptime. [Ryan Bloom]
1507 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1508 should reduce the amount of duplicate code that is required to
1509 create CGI processes.
1510 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1512 *) ap_new_connection() closes the socket and returns NULL if a socket
1513 call fails. Usually this is due to a connection which has been
1514 reset. [Jeff Trawick]
1516 *) Move the Apache version information out of httpd.h and into release.h.
1517 This is in preparation for the first tag with the new tag and release
1518 system. [Ryan Bloom]
1520 *) Begin restructuring scoreboard code to enable adding back in
1521 the ability to use IPC other than shared memory.
1522 Get mod_status working on Windows again. [Bill Stoddard]
1524 *) Make mod_status work with 2.0. This will work for prefork,
1525 mpmt_pthread, and dexter. [Ryan Bloom]
1527 *) Correct a typo in httpd.conf.
1528 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1530 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1532 *) Get the correct IP address if ServerName isn't set and we can't
1533 find a fully-qualified domain name at startup.
1534 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1536 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1538 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1539 'extra' stat's for user/group since they should never occur, and now
1540 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1541 volumes. [William Rowe]
1543 *) Adopt apr features to simplify mod_includes. This changes the
1544 behavior of the USER_NAME variable, unknown uid's are now reported
1545 as USER_NAME="<unknown>" rather than the old user#000 result.
1546 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1548 *) Adopt apr features for simplifing mod_userdir, and accept the new
1549 Win32/OS2 exceptions without hiccuping. [William Rowe]
1551 *) Replace configure --with-optim option by using and saving the
1552 environment variable OPTIM instead. This is needed because configure
1553 options do not support multiple flags separated by spaces.
1556 *) Fix some byterange handling. If we get a byte range that looks like
1557 "-999999" where that is past the end of the file, we should return
1558 a PARTIAL CONTENT status code, and return the whole file as one big
1559 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1561 *) Make the error bucket a real meta-data bucket. This means that the
1562 bucket length is 0, and a read returns NULL data. If one of these
1563 buckets is passed down after the headers are sent, this data will
1564 just be ignored. [Greg Stein]
1566 *) The prefork MPM wasn't killing child processes correctly if a restart
1567 signal was received while the process was serving a request. The child
1568 process would become the equivalent of a second parent process. If
1569 we break out of the accept loop, then we need to do die after cleaning
1570 up after ourselves. [Ryan Bloom]
1572 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1573 restarts. [Ryan Bloom]
1575 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1576 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1577 performing very expensive owner, group and permission lookups
1578 and allows the server to function until these apr_finfo_t fields
1579 are implemented under Win32. [William Rowe]
1581 *) Support for typedsafe optional functions - that is functions exported by
1582 optional modules, which, therefore, may or may not be present, depending
1583 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1584 for sample code. [Ben Laurie]
1586 *) filters can now report an HTTP error to the server. This is done
1587 by sending a brigade where the first bucket is an error_bucket.
1588 This bucket is a simple bucket that stores an HTTP error and
1589 a string. Currently the string is not used, but it may be needed
1590 to output an error log. The http_header_filter will find this
1591 bucket, and output the error text, and then return
1592 AP_FILTER_ERROR, which informs the server that the error web page
1593 has already been sent. [Ryan Bloom]
1595 *) If we get an error, then we should remove all filters except for
1596 those critical to serving a web page. This fixes a bug, where
1597 error pages were going through the byterange filter, even though
1598 that made no sense. [Ryan Bloom]
1600 *) Relax the syntax checking of Host: headers in order to support
1601 iDNS. PR#6635 [Tony Finch]
1603 *) Cleanup the byterange filter to use the apr_brigade_partition
1604 and apr_bucket_copy functions. This removes a lot of very messy
1605 code, and hopefully makes this filter more stable.
1608 *) Remove AddModule and ClearModuleList directives. Both of these
1609 directives were used to ensure that modules could be enabled
1610 in the correct order. That requirement is now gone, because
1611 we use hooks to ensure that modules are in the correct order.
1614 *) When SuExec is specified, we need to add it to the list of
1615 targets to be built. If we don't, then any changes to the
1616 configuration won't affect SuExec, unless 'make suexec' is
1617 specifically run. [Ryan Bloom]
1619 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1620 the APR_XTHREAD argument to open a file for consumption by
1621 parallel threads on win32. [William Rowe]
1623 *) Correct a bug in determining when we follow symlinks. The code
1624 expected a stat -1 result, not an apr_status_t positive error.
1625 Also check if the APR_FINFO_USER fields are valid before we
1626 follow the link. [William Rowe]
1628 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1629 mpm_common.c. These functions are only valid on some platforms,
1630 so they should not be in the main-line code. [Ryan Bloom]
1632 *) Remove ap_chdir_file(). This function is not thread-safe,
1633 and nobody is currently using it. [Ryan Bloom]
1635 *) Do not try to run make depend if there are no .c files in the
1636 current directory, doing so makes `make depend` fail.
1639 *) Update highperformance.conf to work with either prefork or
1640 pthreads mpms. [Greg Ames]
1642 *) Stop checking to see if this is a pipelined request if we know
1643 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1644 This keeps us from making an extra read call when serving a 1.0
1645 request. [Ryan Bloom and Greg Stein]
1647 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1648 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1649 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1651 *) Fix the RFC number mentioned when complaining about a missing
1652 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1654 *) Fix an endless loop in ab which occurred when ab was posting
1655 and the server dropped the connection unexpectedly.
1658 *) Fix a segfault while handling request bodies in ap_http_filter().
1659 This problem has been seen with mod_dav usage as well as with
1660 requests where the body was just being discarded. [Jeff Trawick]
1662 *) Some adjustment on the handling and automatic setting (via
1663 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1664 add the capability to specify flags (NOTEST_CFLAGS and
1665 NOTEST_LDFLAGS) which are used to compile Apache, but
1666 not used during the configuration process. Useful for
1667 flags like "-Werror". [Jim Jagielski]
1669 *) Stop using environment variables to force debug mode or
1670 no detach. We now use the -D command line argument to
1671 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1672 [Greg Stein, Ryan Bloom]
1674 *) Change handlers to use hooks. [Ben Laurie]
1676 *) Stop returning copies of filenames from both apr_file_t and
1677 apr_dir_t. We pstrdup the filenames that we store in the
1678 actual structures, so we don't need to pstrdup the strings again.
1681 *) mod_cgi: Fix some problems where the wrong error value was being
1682 traced. [Jeff Trawick]
1684 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1687 *) Add generic hooks. [Ben Laurie]
1689 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1691 *) Fix a segfault caused by mod_ext_filter when the external filter
1692 program does not exist. [Jeff Trawick]
1694 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1695 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1696 was served through mod_charset_lite (or anything else that would
1697 create a transient bucket in this size range). ap_bucket_make_heap()
1698 silently failed (fixed), transient_setaside() discovered it, but
1699 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1701 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1702 is that some browsers send extra lines at the end of POST requests, and
1703 we don't want to delay sending data back to the user just because the
1704 browser isn't well behaved. [Ryan Bloom]
1706 *) Get SuEXEC working again. We can't send absolute paths to suExec
1707 because it refuses to execute those programs. SuEXEC also wasn't
1708 always recognizing configuration changes made using the autoconf
1711 *) Allow the buildconf process to find the config.m4 files in the correct
1712 order. Basically, we can now name config.m4 files as config\d\d.m4,
1713 and we will sort them correctly when inserting them into the build
1714 process. [Ryan Bloom]
1716 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1717 This also allows mod_cgid to use ap_os_create_priviledged_process,
1718 thus allowing for SuExec execution from mod_cgid. Currently, we do
1719 not support everything that standard SuExec supports, but at least
1720 it works minimally now. [Ryan Bloom]
1722 *) Allow SuExec to be configured from the ./configure command line.
1725 *) Update some of the docs in README and INSTALL to reflect some of
1726 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1728 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1729 need to call sendfile again. This gets us serving large files
1730 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1732 *) Get the support programs building cleanly again.
1733 [Cliff Woolley <cliffwoolley@yahoo.com>]
1735 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1736 current directory logic now backs up over bin/ to determine the
1737 server root from the Apache.exe path.
1739 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1740 loadable modules, dynamic libs are all named libfoo.dll, and the
1741 makefile.win populates the include, lib and libexec directories.
1743 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1744 Apache gets IPv6 listening sockets by default. Additionally, the
1745 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1746 numeric address strings (e.g., "Listen [fe80::1]:8080").
1749 *) Modify the install directory layout. Modules are now installed in
1750 modules/. Shared libraries should be installed in libraries/, but
1751 we don't have any of those on Unix yet. All install directories
1752 are modifyable at configure time. [Ryan Bloom]
1754 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1756 *) Get the functions in server/linked into the server, regardless of
1757 which modules linked into the server. This uses the same hack
1758 for Apache that we use for APR and apr-util to ensure all of the
1759 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1760 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1761 the scripts a bit easier.
1764 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1765 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1767 *) Get all of the auth modules to the point that they will install and
1768 be loadable into the server. Our new build/install mechanism expects
1769 that all modules will have a common name format. The auth modules
1770 didn't use that format, so we didn't install them properly.
1773 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1774 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1776 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1778 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1779 after the end of the response. [Ryan Bloom]
1781 *) Get byterange requests working with responses that do not have a
1782 content-length. Because of the way byterange requests work, we have to
1783 have all of the data before we can actually do the byterange, so we
1784 can compute the content-length in the byterange filter.
1787 *) Get exe CGI's working again on Windows.
1790 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1791 they keep track of whether or not their post config hook has been
1792 called before. Instead of a static variable (which is replaced when
1793 the DSO is loaded a second time), use userdata in the process pool.
1796 Changes with Apache 2.0a9
1798 *) Win32 now requires perl to complete the final install step for users
1799 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1800 and installs the conf, htdocs and htdocs/manual directories.
1803 *) Make mod_include use a hash table to associate directive tags with
1804 functions. This allows modules to implement their own SSI tags easily.
1805 The idea is simple enough, a module can insert it's own tag and function
1806 combination into a hash table provided by mod_include. While mod_include
1807 parses an SSI file, when it encounters a tag in the file, it does a
1808 hash lookup to find the function that implements that tag, and passes
1809 all of the relevant data to the function. That function is then
1810 responsible for processing the tag and handing the remaining data back
1811 to mod_include for further processing.
1812 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1814 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1815 fewer parameters: the local and remote socket addresses were removed
1816 from the parameter list because all required information is available
1817 via the APR socket. [Jeff Trawick]
1819 *) Distribution directory structure reorganized to reflect a
1820 normal source distribution with external install targets.
1823 *) The MPMs that need multiple segments of shared memory now create
1824 two apr_shmem_t variables, one for each shared memory allocation.
1825 the problem is that we can't determine how much memory will be required
1826 for shared memory allocations once we try to allocate more than one
1827 variable. The MM code automatically aligns the shared memory allocations,
1828 so we end up needing to pad the amount of shared memory we want based
1829 on how many variables will be allocated out of the shared memory segment.
1830 It is just easier to create a second apr_shmem_t variable, and two
1831 shmem memory blocks.
1834 *) Cleanup the export list a bit. This creates a single unified list of
1835 functions exported by APR. The export list is generated at configure
1836 time, and that list is then used to generate the exports.c file.
1837 Because of the way the export list is generated, we only export those
1838 functions that are valid on the platform we are building on.
1841 *) Enable logging the cookie with mod_log_config
1842 [Sander van Zoest <sander@covalent.net>]
1844 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1847 *) Added lib/aputil/ as a placeholder for utility functions which are not
1848 specific to the Apache HTTP Server (but do not make sense with APR).
1849 The first utility is "apu_dbm": a set of functions to work with DBM
1850 files. This first version can be compiled for SDBM or GDBM databases.
1853 *) Complete re-write of mod_include. This makes mod_include a filter that
1854 uses buckets directly. This has now served the FAQ correctly.
1855 [Paul Reder <rederpj@raleigh.ibm.com>]
1857 *) Allow modules to specify the first filter in a sub_request when
1858 making the sub_request. This keeps modules from having to change the
1859 output_filter immediately after creating the sub-request, and therefore
1860 skip the sub_req_output_filter. [Ryan Bloom]
1862 *) Update ab to accept URLs with IPv6 literal address strings (in the
1863 format described in RFC 2732), and to build Host header fields in
1864 the same format. This allows IPv6 literal address strings to be
1865 used with ab. This support has been tested against Apache 1.3 with
1866 the KAME patch, but Apache 2.0 does not yet work with this format
1867 of the Host header field. [Jeff Trawick]
1869 *) Accomodate an out-of-space condition in the piped logs and the
1870 rotatelogs.c code, and no longer churn log processes for this
1871 condition. [Victor J. Orlikowski]
1873 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1876 Changes with Apache 2.0a8
1878 *) Add a directive to mod_mime so that filters can be associated with
1882 *) Get multi-views working again. We were setting the path_info
1883 field incorrectly if we couldn't find the specified file.
1886 *) Fix 304 processing. The core should never try to send the headers
1887 down the filter stack. Always, just setup the table in the request
1888 record, and let the header filter convert it to data that is ready
1892 *) More fixes for the proxy. There are still bugs in the proxy code,
1893 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1897 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1900 *) APR: Add new apr_getopt_long function to handle long options.
1901 [B. W. Fitzpatrick <fitz@red-bean.com>]
1903 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1904 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1905 hostname resolution/address string parsing and building
1906 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1907 of one of the apr_sockaddr_t structures for a socket. Change
1908 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1910 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1911 I have proxied pages with it, cleanup will commence soon.
1914 *) Make the proxy work with filters. This isn't perfect, because we
1915 aren't dealing with the headers properly. [Ryan Bloom]
1917 *) Do not send a content-length iff the C-L is 0 and this is a head
1918 request. [Ryan Bloom]
1920 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1921 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1923 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1925 *) Get the default_handler to stop trying to deal with HEAD requests.
1926 The idea is to let the content-length filter compute the C-L before
1927 we try to send the data. If we can get the C-L correctly, then we
1928 should send it in the HEAD response.
1931 *) The Header filter can now determine if a body should be sent based
1932 on r->header_only. The general idea of this is that if we delay
1933 deciding to send the body, then we might be able to compute the
1934 content-length correctly, which will help caching proxies to cache
1935 our data better. Any handler that doesn't want to try to compute
1936 the content-length can just send an EOS bucket without data and
1937 everything will just work.
1940 *) Add the referer to the error log if one is available.
1941 [Markus Gyger <mgyger@itr.ch>]
1943 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1944 change, the root of the configuration tree has been exposed to modules
1946 [Ryan Morgan <rmorgan@covalent.net>]
1948 *) Get the core_output_filter to use the bucket interface directly.
1949 This keeps us from calling the content-length filter multiple times
1950 for a simple static request.
1953 *) We are sending the content-type correctly now.
1954 [Ryan Bloom and Will Rowe]
1956 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1957 a bogus bytes-sent value when the only thing being sent was trailers
1958 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1960 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1961 hints file to determine which platforms define
1962 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1965 *) APR: add apr_get_home_directory() [Jeff Trawick]
1967 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1969 *) Not all platforms have INADDR_NONE defined by default. Apache
1970 used to make this check and define INADDR_NONE if appropriate,
1971 but APR needs the check too, and I suspect other applications will
1972 as well. APR now defines APR_INADDR_NONE, which is always a valid
1973 value on all platforms.
1974 [Branko Èibej <brane@xbc.nu>]
1976 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1977 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1979 *) Relax the syntax checking of Host: headers in order to support
1980 iDNS. PR#6635 [Tony Finch]
1982 *) When reading from file buckets we convert to an MMAP if it makes
1983 sense. This also simplifies the default handler because the
1984 default handler no longer needs to try to create MMAPs.
1987 *) BUFF has been removed from the main server. The BUFF code will remain
1988 in the code until it has been purged from the proxy module as well.
1991 *) Byteranges have been completely re-written to be a filter. This
1992 has been tested, and I believe it is working correctly, but it could
1993 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1994 the output from 1.3, the only difference being that 1.3 includes
1995 a content-length in the response, and this does not.
1998 *) APR read/write functions and bucket read functions now operate
1999 on unsigned integers, instead of signed ones. It doesn't make
2000 any sense to use signed ints, because we return the error codes,
2001 so if we have an error we should report 0 bytes read or written.
2004 *) Always compute the content length, whether it is sent or not.
2005 The reason for this, is that it allows us to correctly report
2006 the bytes_sent when logging the request. This also simplifies
2007 content-length filter a bit, and fixes the actual byte-reporing
2008 code in mod_log_config.c
2011 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
2012 it says, because it was only used by EOS and FLUSH buckets. Since
2013 neither of those are required at the end of a brigade, this was
2014 really signifying FLUSH_THE_DATA, but that can be determined better
2015 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
2016 buckets now return a length of 0, which is actually the amount of data
2017 read, so they make more sense.
2020 *) Allow the core_output_filter to save some data past the end of a
2021 request. If we get an EOS bucket, we only send the data if it
2022 makes sense to send it. This allows us to pipeline request
2023 responses. As a part of this, we also need to allocate mmap
2024 buckets out of the connection pool, not the request pool. This
2025 allows the mmap to outlive the request.
2028 *) Make blocking and non-blocking bucket reads work correctly for
2029 sockets and pipes. These are the only bucket types that should
2030 have non-blocking reads, because the other bucket types should
2031 ALWAYS be able to return something immediately.
2034 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
2035 server, but use Ctrl+Break to initiate a graceful restart
2036 instead of duplicating behavior. [John Sterling]
2038 *) Patch mod_autoindex to set the Last-Modified header based on
2039 the directory's mtime, and add the ETag header. [William Rowe]
2041 *) Merge the 1.3 patch to add support for logging query string in
2042 such a way that "%m %U%q %H" is the same as "%r".
2045 *) Port three log methods from mod_log_config 1.3 to 2.0:
2046 CLF compliant '-' byte count, method and protocol.
2049 *) Add a new LogFormat directive, %c, that will log connection
2050 status at the end of the response as follows:
2051 'X' - connection aborted before the response completed.
2052 '+' - connection may be kept-alive by the server.
2053 '-' - connection will be closed by the server.
2056 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2057 Unicode file names and paths for Win32, and tag the Content-Type
2058 from mod_autoindex to reflect that charset if the the feature
2059 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2061 *) Compute the content length (and add appropriate header field) for
2062 the response when no content length is available and we can't use
2063 chunked encoding. [Jeff Trawick]
2065 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2066 so that content input filters get dechunked data when using
2067 the default handler. Also removed REQUEST_CHUNKED_PASS.
2070 *) Add mod_ext_filter as an experimental module. This module allows
2071 the administrator to use external programs as filters. Currently,
2072 only filtering of output is supported. [Jeff Trawick]
2074 *) Most Apache functions work on EBCDIC machines again, as protocol
2075 data is now translated (again). [Jeff Trawick]
2077 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2078 the EBCDIC support. They are noops on ASCII machines, so this
2079 type of translation doesn't have to be surrounded by #ifdef
2080 CHARSET_EBCDIC. [Jeff Trawick]
2082 *) Fix mod_include. tag commands work again, and the server will
2083 send the FAQ again. This also allows mod_include to set aside
2084 buckets that include partial buckets.
2085 [Ryan Bloom and David Reid]
2087 *) Add suexec support back. [Manoj Kasichainula]
2089 *) Lingering close now uses the socket directly instead of using
2090 BUFF. This has been tested, but since all we can tell is that it
2091 doesn't fail, this needs to be really hacked on.
2094 *) Allow filters to modify headers and have those headers be sent to
2095 the client. The idea is that we have an http_header filter that
2096 actually sends the headers to the network. This removes the need
2097 for the BUFF to send headers.
2100 *) Charset translation: mod_charset_lite handles translation of
2101 request bodies. Get rid of the xlate version of ap_md5_digest()
2102 since we don't compute digests of filtered (e.g., translated)
2103 response bodies this way anymore. (Note that we don't do it at
2104 all at the present; somebody needs to write a filter to do so.)
2107 *) Input filters and ap_get_brigade() now have a input mode parameter
2108 (blocking, non-blocking, peek) instead of a length parameter.
2111 *) Update the mime.types file to the registered media types as
2112 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2115 *) Namespace protect some macros declared in ap_config.h
2118 *) Support HTTP header line folding with input filtering.
2121 *) Mod_include works again. This should still be re-written, but at
2122 least now we can serve an SHTML page again.
2125 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2126 to both the BUFF and the socket in the conn_rec. Functions that
2127 want to use the BUFF can, functions that want to use the socket,
2128 can. They point to the same place.
2131 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2132 [Tomas "Ögren" <stric@ing.umu.se>]
2134 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2135 associated pool goes away. (APR pipes on OS/2 were already had this
2136 logic.) This resolvs a fatal file descriptor leak with CGIs.
2139 *) The final line of the config file was not being read if there was
2140 no \n at the end of it. This was caused by apr_fgets returning
2141 APR_EOF even though we had read valid data. This is solved by
2142 making cfg_getline check the buff that was returned from apr_fgets.
2143 If apr_fgets return APR_EOF, but there was data in the buf, then we
2144 return the buf, otherwise we return NULL.
2147 *) Piped logs work again in the 2.0 series.
2150 *) Restore functionality broken by the mod_rewrite security fix:
2151 rewrite map lookup keys and default values are now expanded
2152 so that the lookup can depend on the requested URI etc.
2153 PR #6671 [Tony Finch]
2155 *) Tighten up the syntax checking of Host: headers to fix a
2156 security bug in some mass virtual hosting configurations
2157 that can allow a remote attacker to retrieve some files
2158 on the system that should be inaccessible. [Tony Finch]
2160 *) Add a pool bucket type. This bucket is used for data allocated out
2161 of a pool. If the pool is cleaned before the bucket is destroyed, then
2162 the data is converted to a heap bucket, allowing it to survive the
2166 *) Add a flush bucket. This allows modules to signal that the filters
2167 should all flush whatever data they currently have. There is no way
2168 to actually force them to do this, so if a filter ignores this bucket,
2169 that's life, but at least we can try with this.
2172 *) Add an output filter for sub-requests. This filter just strips the
2173 EOS bucket so that we don't confuse the main request's core output
2174 filter by sending multiple EOS buckets. This change also makes sub
2175 requests start to send EOS buckets when they are finished.
2178 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2179 makes ap_bucket_destroy a return void, which is okay because it
2180 used to always return APR_SUCCESS, and nobody ever checked its
2181 return value anyway.
2182 [Cliff Woolley <cliffwoolley@yahoo.com>]
2184 *) Remove the index into the bucket-type table from the buckets
2185 structure. This has now been replaced with a pointer to the
2186 bucket_type. Also add some macros to test the bucket-type.
2189 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2190 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2191 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2192 All _VAR_ flavors changes to _DATA to be absolutely clear.
2195 *) Add support for /, //, //servername and //server/sharename
2196 parsing of <Directory> blocks under Win32 and OS2.
2197 [Tim Costello, William Rowe, Brian Harvard]
2199 *) Remove the function pointers from the ap_bucket type. They have been
2200 replaced with a global table. Modules are allowed to register bucket
2201 types and use then use those buckets.
2204 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2205 once we finish writing the request body to the cgi child process;
2206 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2207 worked without this change (for reasons I don't understand), but large
2208 ones didn't. [Jeff Trawick]
2210 *) Remove file bucket specific information from the ap_bucket type.
2211 This has been moved to a file_bucket specific type that hangs off
2212 the data pointer in the ap_bucket type.
2215 *) Input filtering now has a third argument. This is the amount of data
2216 to read from lower filters. This argument can be -1, 0, or a positive
2217 number. -1 means give me all the data you have, I'll deal with it and
2218 let you know if I need more. 0 means give me one line and one line
2219 only. A positive number means I want no more than this much data.
2221 Currently, only 0 and a positive number are implemented. This allows
2222 us to remove the remaining field from the conn_rec structure, which
2226 *) Big cleanup of the input filtering. The goal is that http_filter
2227 understands two conditions, headers and body. It knows where it is
2228 based on c->remaining. If c->remaining is 0, then we are in headers,
2229 and http_filter returns a line at a time. If it is not 0, then we are
2230 in body, and http_filter returns raw data, but only up to c->remaining
2231 bytes. It can return less, but never more.
2232 [Greg Ames, Ryan Bloom, Jeff Trawick]
2234 *) mod_cgi: Write all of the request body to the child, not just what
2235 the kernel would accept on the first write. [Jeff Trawick]
2237 *) Back out the change that moved the brigade from the core_output_filters
2238 ctx to the conn_rec. Since all requests over a given connection
2239 go through the same core_output_filter, the ctx pointer has the
2243 *) Fix another bug in the send_the_file() read/write loop. A partial
2244 send by apr_send would cause unsent data in the read buffer to
2245 get clobbered. Complete making send_the_file handle partial
2246 writes to the network.
2249 *) Fix a couple of type fixes to allow compilation on AIX again
2250 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2252 *) Fix bug in send_the_file() which causes offset to be ignored
2253 if there are no headers to send.
2256 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2257 filter. Useful for supporting Windows 9* with a binary
2258 compiled on Windows NT.
2261 Changes with Apache 2.0a7
2263 *) Reimplement core_output_filter to buffer/save bucket brigades
2264 across multiple calls to the core_filter. The brigade will be
2265 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2266 thresholds are hit or the EOS bucket is received.
2269 *) Create experimental filter (buffer_filter) that coalesces bytes
2270 into one large buffer before invoking the next filter in the
2271 chain. This filter is particularly useful with the current
2272 implementation of mod_autoindex when it inserted above the
2273 chunk_filter. mod_autoindex generates a lot of brigades that
2274 containing buckets holding just a few bytes each. The
2275 buffer_filter coalesces these buckets into a single large bucket.
2278 *) Add apr_sendfile() support into the core_output_filter.
2281 *) Add apr_sendv() support into the core_output_filter.
2284 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2285 [Mike Abbott <mja@sgi.com>]
2287 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2288 make much sense, because Apache uses buckets instead of BUFFs now.
2291 *) send_the_file now falls back to a read/write loop on platforms that
2292 do not have sendfile.
2293 [Ryan Bloom and Brian Havard]
2295 *) Install apachectl correctly, and substitute the proper values so
2296 that it works again. [Ryan Bloom]
2298 *) Better(??) handle platforms that lack sendfile().
2301 *) APR now has UUID generation/formatting/parsing support.
2304 *) Begin the http_filter. This is an input filter that understands
2305 the absolute basic amount required to parse an HTTP Request. The
2306 goal is to be able to split headers from request body before passing
2307 the data back to the other filters.
2310 *) Bring forward from 1.3.13 the config directory implementation
2313 *) install apxs if it is created
2316 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2317 conversions. [William Rowe]
2319 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2320 ap_add_output_filter(). [Jeff Trawick]
2322 *) Multiple build and configuration fixes
2325 -add datadir and localstatedir substitutions
2327 -fix logfilename misspelling
2328 -fix evaluation of installation dir variables and
2329 -replace $foobar by $(foobar) to be usefull in the makefile
2333 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2334 $CC_FOR_BUILD is still missing
2335 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2336 -add missing "AR=@AR@" to severaly Makefile.in's
2337 -cache result for "struct rlimit"
2338 -compile all helper programs with native and cross compiler
2339 and use the native version to generate header file
2340 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2342 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2344 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2346 *) Fix a bug where a client which only sends \n to delimit header
2347 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2348 message. Start working on ebcdic co-existance with input
2350 [William Rowe, Greg Ames]
2352 *) If mod_so is enabled in the server always create libexec, even
2353 if there are no modules installed in this directory. This is a
2354 requirement for APXS to work correctly.
2357 *) Connection oriented output filters are now stored in the
2358 conn_rec instead of the request_rec. This allows us to add the
2359 output filter in the pre-connection phase instead of the
2360 post_read_request phase, which keeps us from trying to write an
2361 error page before we have a filter to write to the network.
2362 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2364 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2365 mmap can be used across multiple buckets (default_handler with
2366 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2367 the mmap itself can't be associated with the bucket.
2370 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2373 *) Radical surgery to improve mod_isapi support under Win32.
2374 Includes a number of newer ServerSupportFunction calls, support
2375 for ReadClient (in order to retrieve POSTs greater than 48KB),
2376 and general bug fixes to more reliably load ISAPI .dll's and
2377 prevent leaking handle resources. Note: There are still
2378 discrepancies between IIS's and Apache's ServerVariables, and
2379 async calls are still not supported. Additional warnings are
2380 logged to facilitate debugging of unsupported ISAPI calls.
2383 *) Add input filtering to Apache. The basic idea for the input
2384 filters is the same as the ideas for output filters. The biggest
2385 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2386 should be called, and the order of execution for the filter itself is
2387 different. When writing an output filter, a brigade is passed in,
2388 and filters operate directly on that brigade, when done, they call
2389 ap_pass_brigade. Input filters are the exact opposite. Because input
2390 is not a push operation, filters first call ap_get_brigade. When this
2391 function returns, the input filter will be left with a valid brigade.
2392 The input filter should then operate on the brigade, and return.
2395 *) Fix building on BSD/OS using its native make. The build system
2396 falls back to the BSD .include directive on that host platform.
2399 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2400 SHA1 and plaintext password encodings. Make feature tests a
2401 bit more flexible. [William Rowe]
2403 *) Charset translation: mod_charset_lite handles output content
2404 translation in a filter. mod_charset_lite no longer ignores
2405 subrequests. A bunch of cruft related to BUFF's support for
2406 translating request and response bodies was removed.
2409 *) Move the addition of the CORE filter to the post_read_request
2410 hook in http_core.c. This removes the need to add the filter in
2411 multiple places and allows for an SSL module to be added much
2412 simpler. [Ryan Bloom]
2414 *) Fix a security problem that affects certain configurations of
2415 mod_rewrite. If the result of a RewriteRule is a filename that
2416 contains expansion specifiers, especially regexp backreferences
2417 $0..$9 and %0..%9, then it may be possible for an attacker to
2418 access any file on the web server. [Tony Finch]
2420 *) Fix a bug where errors that are detected during early request parsing
2421 don't produce visible HTTP error messages at the browser, because
2422 the core_filter wasn't present. [Greg Ames]
2424 *) Provide apr_socklen_t as a portability aid.
2425 [Victor J. Orlikowski]
2427 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2428 as well as a comment arg to the add, adduser and update cmds.
2429 update allows the user to clear or preserve pw/groups/comment.
2430 Fixed a bug in dbmmanage that prevented the check option from
2431 parsing a password followed by :group... text. Corrected the
2432 seed calcualation for Win32 systems, and added -lsdbm support.
2435 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2438 *) Avoid a segfault when parsing .htaccess files. An
2439 uninitialized tree pointer was passed to ap_build_config().
2442 *) Change the way that inet_addr & inet_network are checked for
2443 in APR's configure process to allow BeOS BONE to correctly
2444 find them. With this change BeOS BONE now builds from source
2445 with no problems. [David Reid]
2447 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2448 the end of the parameters to execve() was stored in the wrong
2449 location, overlaying the storage beyond the newargs[] array and
2450 also passing uninitialized storage to execve(), which would
2451 sometimes fail with EFAULT. [Jeff Trawick]
2453 *) Fix a bug parsing configuration file containers. With a sequence
2454 like this in the config file
2456 <IfModule mod_kilroy.c>
2459 <IfModule mod_lovejoy.c>
2464 the second container would be terminated at the blank line due to
2465 sediment in the buffer from reading the prior </IfModule> and an
2466 error message would be generated for the real </IfModule> for the
2467 second container. Also due to this problem, any two characters
2468 could be used for "</" in the close of a container.
2471 *) ap_add_filter prototype changed to remove the ctx pointer. The
2472 pointer still remains in the filter structure, but it can not be
2473 a part of the ap_add_filter prototype. The reason is that when
2474 the core uses AddFilter to add a filter to the stack it doesn't
2475 know how to allocate the ctx pointer, or even how much memory should
2476 be allocated. The filters will have to be responsible for allocating
2477 the ctx memory when they need it.
2480 *) Add an AddFilter directive. This directive takes a list of filters
2481 that should be activated for the requested resource.
2484 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2485 some other platforms). [Jeff Trawick]
2487 *) Modify mod_include to be a filter. Currently, it has only been tested
2488 on actual files, but it should work for CGI scripts too.
2491 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2492 writes. apr_flush() for Unix: handle interrupted writes.
2495 *) NameVirtualHost can now take "*" as an argument instead of
2496 an IP address. This allows you to create a purely name-based
2497 virtual hosting server that does not have any IP addresses in
2498 the configuration file and which ignores the local address
2499 of any connections. PR #5595, PR #4455 [Tony Finch]
2501 *) Fix some compile warnings in mod_mmap_static.c
2502 [Mike Abbott <mja@sgi.com>]
2504 *) Fix chunking problem with CGI scripts. The general problem was that
2505 the CGI modules were adding an EOS bucket and then the core added an
2506 EOS bucket. The chunking filter finalizes the chunked response when it
2507 encounters an EOS bucket. Because two EOS buckets were sent, we
2508 finalized the response twice. The fix is to make sure we only send one
2509 EOS, by utilizing a flag in the request_rec.
2512 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2513 and Win32. Previously, the first read from an apr_file_t set up via
2514 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2516 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2517 bucket, instead of using BUFF's and ap_r*.
2520 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2521 [Mike Abbott <mja@sgi.com>]
2523 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2524 code to use APR file's directly instead of going through BUFFs.
2527 *) Fix compile break on some platforms for mod_mime_magic.c
2528 [John K. Sterling <sterling@covalent.net>]
2530 *) Fix merging of AddDefaultCharset directive.
2531 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2533 *) Minor revamp of the rlimit sections of code. We now test
2534 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2535 is now "available" even if the platform doesn't support
2536 the rlimit family (it's just a noop though). [Jim Jagielski]
2538 *) Migrate the pre-selection of which MPM to use for specific
2539 platforms to hints.m4, which contains (or should contain)
2540 all platform specific "hints". [Jim Jagielski]
2542 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2545 *) Add tables with non-string/binary values to APR.
2548 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2551 *) Update PCRE to version 3.2. [Ryan Bloom]
2553 *) Change the way buckets' destroy functions are called so that
2554 they can be more directly used when changing the type of a
2555 bucket in place. [Tony Finch]
2557 *) Add generic support for reference-counting the resources used by
2558 buckets, and alter the HEAP and MMAP buckets to use it. Change
2559 the way buckets are initialised to support changing the type of
2560 buckets in place, and use it when setting aside TRANSIENT buckets.
2561 Change the implementation of TRANSIENT buckets so that it can be
2562 mostly shared with IMMORTAL buckets, which are now implemented.
2565 Changes with Apache 2.0a6
2567 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2569 *) Add a chunking filter to Apache. This brings us one step closer
2570 to removing BUFF. [Ryan Bloom]
2572 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2573 added to the stack is the last filter to be called. [Ryan Bloom]
2575 *) Apache 2.0 has been completely documented using Scandoc. The
2576 docs can be generated by running 'make docs'. [Ryan Bloom]
2578 *) Add filtered I/O to Apache. This is based on bucket brigades,
2579 Currently the buckets still use BUFF under the covers, but that
2580 should change quickly. The only currently written filter is the
2581 core filter which just calls ap_bwrite. [The Apache Group]
2583 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2584 built with thread support. [Jeff Trawick]
2586 *) Abort configuration if --with-layout was specified and there's
2587 no layout definition file. [Ken Coar]
2589 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2591 *) Add support for extension methods for the Allow response header
2592 field, and an API routine for accessing r->allowed and the
2593 list of extension methods in a unified manner. [Ken Coar]
2595 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2596 [Rob Simonson <simo@us.ibm.com>]
2598 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2599 APACHE_XLATE builds. [Jeff Trawick]
2601 *) A configuration file parsing problem was fixed. When the
2602 configuration file started with an IfModule/IfDefine container,
2603 only the last statement in the container would be retained.
2606 Changes with Apache 2.0a5
2608 *) Perchild is serving pages after passing them to different child
2609 processes. There are still a lot of bugs, but this does work. I
2610 have made requests against the same installation of Apache, and had
2611 different servers use different user IDs to serve the responses.
2612 This change moves to using socketpair instead of an AF_UNIX socket.
2615 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2616 It can't seem to pass between child processes yet, but I think we
2617 are closer now than before. This moves us back to using Unix
2618 Domain Sockets. [Ryan Bloom]
2620 *) libapr functions and types renamed with apr_ prefix.
2621 #include "apr_compat.h" for 1.3.x backwards compat
2624 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2625 return the right information on the local socket address.
2626 [Gregory Nicholls <gnicholls@level8.com>]
2628 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2629 [Gregory Nicholls <gnicholls@level8.com>]
2631 *) Add an option to not detach from the controlling terminal without
2632 going into single process mode. This allows for much easier
2633 debugging of the process startup code. [Ryan Bloom]
2635 *) ab: don't use perror() to report the failure of an APR function.
2638 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2639 scoreboard on graceful restarts.
2642 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2643 An invalid ap_proc_t was passed to ap_create_process().
2646 *) Allow modules to register filters. Those filters are still
2647 never called, but this is a step in the right direction.
2648 [Ryan Bloom and Greg Stein]
2650 *) Register the mod_cgid daemon process for cleanup so that it is
2651 killed at termination if it does not die when the parent gets
2652 SIGTERM. This change is to fix occasional problems where the
2653 process stays around. Bugs in similar logic in mod_rewrite and
2654 mod_include were also fixed. [Jeff Trawick]
2656 *) Fix a bug in the time handling. Basically, we were imploding a time
2657 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2658 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2659 uses those two fields to adjust the time value. Because of the HTTP
2660 spec, both of those values can be zero'ed out safely. This fixes
2661 the bug correctly. [Ryan Bloom]
2663 *) Fix a couple of place in the Windows code where the wrong error
2664 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2666 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2668 *) Added the APR_EOL_STR macro for platform dependent differences in
2669 logfiles and other raw text (such as all APR files). Fixes logfiles
2670 not terminated with cr/lf sequences in Win32. [William Rowe]
2672 *) Move all strings functions in APR to src/lib/apr/strings and create
2673 apr_strings.h for the prototypes. [Ryan Bloom]
2675 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2676 to repeat the syscall until we stop getting EINTR. I noticed a
2677 related problem at termination (SIGTERM) on FreeBSD when using
2678 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2679 implementation work properly with child init. Previously, ap_lock()
2680 was essentially a no-op because all children were using different
2681 locks and thus nobody ever blocked. [Jeff Trawick]
2683 *) The htdocs/ tree has been moved out of the CVS source tree into
2684 a separate area for easier development. This has NO EFFECT on
2685 end-users or Apache installations. [Ken Coar]
2687 *) Integrate the mod_dav module for WebDAV protocol handling. This
2688 adds the dav and dav_fs modules, the SDBM library, and additional
2689 XML handling utilities. [Greg Stein]
2691 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2694 *) Update the lib/expat-lite/ library (bring forward changes from
2695 the Apache 1.3 repository). [Greg Stein]
2697 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2698 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2700 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2701 machines where sendfile is detected, but nobody has written ap_sendfile.
2702 [Dave Hill <ddhill@zk3.dec.com>]
2704 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2706 *) ab would start up more connections than needed, then quit when the
2707 desired number were finished. Also fixed a logic error involving
2708 ab keepalives. [Victor J. Orlikowski]
2710 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2711 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2712 timeouts (i.e, if a timeout was specified, the pipe reverted to
2713 a full blocking pipe). Now the behaviour is more in line with
2714 Unix non-blocking pipes.
2717 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2718 cache open file handles along with accept socket reuse enables
2719 Apache 2.0 to serve non-keepalive requests for static files at
2720 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2721 and Apache 2.0 will serve almost 1200 rps on my system).
2724 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2725 supports two config directives, mmapfile (same behavious as
2726 mod_mmap_static) and cachefile. Use the cachefile directive
2727 to cache open file handles. This directive only works on systems
2728 that have implemented the ap_sendfile API. cachefile works today
2729 on Windows NT, but has not been tested on any flavors of Unix.
2732 *) Cleanup the configuration. With the last few changes the
2733 configuration process automatically:
2734 inherits information about how to build from APR. Allowing
2735 APR to inform Apache that it should or should not use -ldl
2737 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2738 based on the threading model
2740 Apache calls APR's configure process before finishing it's
2741 configuration processing, allowing for more information flow
2746 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2747 with non-zero argument makes the socket non-blocking. BeOS and
2748 OS/2 already worked this way. [Jeff Trawick]
2750 *) ap_close() now calls ap_flush() for buffered files, so write
2751 operations work a whole lot better on buffered files.
2754 *) Fix error messages issued from MPMs which explain where to change
2755 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2758 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2759 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2760 now the way that the blocking state of a pipe is manipulated.
2761 ap_block_pipe() is gone. [Jeff Trawick]
2763 *) Correct the problem where the only local host name that the IP stack
2764 can discover are 'undotted' private names. If no fully qualified
2765 domain name can be identified, the default ServerName will be set to
2766 the machine's IP address string. A warning is always provided if the
2767 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2769 *) Repair problems with config file processing which caused segfault
2770 at init when virtual hosts were defined and which caused ServerName to
2771 be ignored when there was no valid DNS setup. [Jeff Trawick]
2773 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2775 *) Add ap_sendfile implementation for AIX
2776 [Victor J. Orlikowski]
2778 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2779 apr_network_io.h, and apr_thread_proc.h.
2780 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2782 *) Bring the allocation and pool debugging code back into a working
2783 state. This will need to be tested as so far it's only been used on
2786 *) Change configuration command setup to be properly typesafe when in
2787 maintainer mode. Note that this requires a compiler that can initialise
2788 unions. [Ben Laurie]
2790 *) Turn on buffering for config file reads. Part of this was to
2791 repair buffered I/O support in Unix and implement buffered
2792 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2794 *) Win32: Fix problem where UTC offset was not being set correctly
2795 in the access log. Problem reported on news group by Jerry Baker.
2798 *) Fix segfault when reporting this type of syntax error:
2799 "</container> without matching <container> section", where
2800 container is VirtualHost or Directory or whatever.
2803 *) Prevent the source code for CGIs from being revealed when using
2804 mod_vhost_alias and the CGI directory is under the document root
2805 and a user makes a request like http://www.example.com//cgi-bin/cgi
2806 as reported in <news:960999105.344321@ernani.logica.co.uk>
2809 *) Add support for the new Beos NetwOrking Environment (BONE)
2812 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2813 final input char is incomplete; ap_bwrite_xlate() now handles
2814 incomplete final input chars. [Jeff Trawick]
2816 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2817 that a bhalfduplex call occurs before logging or else DNS and
2818 such can delay the last packet of the response. [Dean Gaudet]
2820 *) Some syscall reduction in APR on unix -- don't seek when setting
2821 up an mmap; and don't fcntl() more than once per socket.
2824 *) When mod_cgid is started as root, the cgi daemon now switches
2825 to the configured User/Group (like other httpd processes)
2826 instead of continuing as root. [Jeff Trawick]
2828 *) The prefork MPM now uses an APR lock for the accept() mutex.
2829 It has not been getting a lock at all recently. httpd -V now
2830 displays APR's selection of the lock mechanism instead of the
2831 symbols previously respected by prefork. [Jeff Trawick]
2833 *) Change the mmap() feature test to check only for existence.
2834 The previous check required features not used by Apache.
2837 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2838 sometimes mangled. The len parm to accept() was not
2839 initialized, leading sometimes to an endless loop of failed
2840 accept() calls on OS/390 and anywhere else that failed the call
2841 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2842 instead of declaring it ourselves to fix a compilation problem
2843 on Solaris. [Jeff Trawick]
2845 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2847 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2849 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2851 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2852 initialization if ALLOC_DEBUG is defined; no known symptom
2853 otherwise. [Jeff Trawick]
2855 *) Fix typo in configure script when checking for mod_so. bash
2856 doesn't seem to have a problem but /bin/sh on Solaris does.
2857 Symptom: "./configure: test: unknown operator =="
2860 *) Rebind the Win32 NT and 9x services control into the MPM.
2861 All console, WinNT SCM and Win9x pseudo-service control code is
2862 now wrapped within the WinNT MPM.
2865 *) Make a copy of getenv("PATH") before storing for later use. Some
2866 getenv() implementations use the same storage for successive calls.
2867 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2869 *) Server Tokens work in 2.0 again. This also propogates the change
2870 to allow just the product name in the server string using
2874 Changes with Apache 2.0a4
2876 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2877 won't need to call it. [Greg Ames, Jeff Trawick]
2879 *) Move pre_config hook call to between configuration read and config
2880 tree walk. This allows all modules to implement pre_config hooks
2881 and know that they will be called at an appropriate time.
2884 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2887 *) Add pre-config hooks back to all modules.
2890 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2891 ContentDigest enabled and we can't/don't mmap the file.
2894 *) We now report the correct line number for syntax errors in config
2895 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2897 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2898 related bugs, and changed shmem/locking to use apr API. Shared-mem
2899 is currently disabled, however, because of problems with graceful
2900 restarts. [Ronald Tschalär]
2902 *) Fix corruption of IFS variable in --with-module= handling.
2903 Depending on the user's shell or customization thereof, there
2904 would be errors generating ap_config_auto.h later in the configure
2905 procedure. [Jeff Trawick]
2907 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2908 isn't used (as in 1.3), except that on Unix it is now logged via
2909 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2910 to the error log. [Greg Ames, Jeff Trawick]
2912 *) Add '-D' argument processing for run time configuration defines.
2915 *) Organize http_main.c as independent code, such that no code or
2916 global data is exported from it. WIN32 will dynamically link it
2917 to the server core, so this will prevent mutual dependency.
2920 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2921 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2924 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2925 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2927 *) Add mod_charset_lite for configuring character set translation.
2930 *) Add '-n' option to htpasswd to make it print its user:pw record
2931 on stdout rather than having to frob a text file. [Ken Coar]
2933 *) Fix saferead. Basically, we flush the output buffer if a read on the
2937 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2938 a conversion is single-byte only. [Jeff Trawick]
2940 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2941 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2944 *) Fix some minor errors where pid was being manipulated as an int
2945 instead of the portable pid_t. [Roy Fielding]
2947 *) Fix some error log prints that were printing the pointer to a
2948 structure rather than the pid within the structure.
2949 [Jeff Trawick, Roy Fielding]
2951 *) ab: Fix a command-line processing bug; track bad headers in
2952 err_response; support reading headers up to 2K.
2953 [Ask Bjoern Hansen <ask@valueclick.com>]
2955 *) Fix ap_resolve_env() so that it handles new function added in a prior
2956 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2957 config file.") as well as the constructs used by mod_rewrite.
2958 [Paul Reder <rederpj@raleigh.ibm.com>]
2960 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2962 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2963 APR to perform translation, instead of accessing the hard-coded tables
2964 in 1.3's ebcdic.c. [Jeff Trawick]
2966 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2969 *) Add the ability to hook into the config file reading phase. Basically
2970 if a directive is specified EXEC_ON_READ, then when that directive is
2971 read from the config file, the assocaited function is executed. This
2972 should only be used for those directives that must muck with HOW the
2973 server INTERPRETS the config. This should not be used for directives
2974 that re-order or replace items in the config tree. Those changes should
2975 be made in the pre-config step.
2978 *) Add mod_example to the build system.
2981 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2982 byte character sets. [Jeff Trawick]
2984 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2985 Kraemer and Oliver Reh originally according to the change log).
2988 *) Fix a couple of problems in RFC1413 support (controlled by the
2989 IdentityCheck directive). Apache did not build the request string
2990 properly and more importantly Apache would loop forever if the
2991 would-be ident server dropped the connection before sending a
2992 properly terminated response. [Jeff Trawick]
2994 *) apxs works in 2.0.
2997 *) Reliable piped logs work in 2.0.
3000 *) Introduce a hash table implementation into APR to be used for
3001 replacing tables and other random data structures in Apache.
3004 *) Add some more error reporting to htpasswd in the case of problems
3005 generating or accessing the temporary file. Also, pass in a
3006 buffer if the implementation knows how to use it (i.e., if L_tmpnam
3007 is defined). [Ken Coar]
3009 *) Configure creates config.nice now containing your configure
3010 options. Syntax: ./config.nice [--more-options]
3013 *) Fix various return code problems in APR on Win32. For most of
3014 these, APR was returning APR_EEXIST instead of GetLastError()/
3015 WSAGetLastError(). [Jeff Trawick]
3017 *) Make piped logs work again in version 2.0
3020 *) Add VPATH support to UNIX build system of Apache and APR.
3023 *) Fix ap_tokenize_to_argv to respect the const arguments that are
3027 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
3028 Patch submitted to author.
3031 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
3032 /sbin in PATH on FreeBSD (all submitted to rse previously)
3035 *) Fix building Pthread-based MPMs on OpenBSD
3036 [Sascha Schumann] PR#26
3038 *) Fix ap_readdir() problem on systems where d_name[] field in
3039 struct dirent is declared with only one byte. (This problem only
3040 affected multithreaded builds.) This caused a segfault during
3041 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3042 least). [Jeff Trawick]
3044 *) Fix some make-portability problems on at least Tru64, Irix
3046 [Sascha Schumann] PR#18, PR#39
3048 *) Add ap_sigwait() to support old-style sigwait() on systems
3049 like OS/390 and UnixWare.
3052 *) Add POSIX-thread flags for more platforms.
3055 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3056 (on Unix, at least) to handle resolver errors. Fix a bug in
3057 the definition of APR_ENOMEM so that ap_strerror() can spit
3058 out the correct error message for it.
3061 Changes with Apache 2.0a3
3063 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3066 *) API: *HOOK* macros now have an AP_ prefix
3069 *) Win32: Eliminate redundant calls to initialize winsock.
3070 [Tim Costello <timcostello@ozemail.com.au>]
3072 *) Fix bugs initializing ungetchar for pipes.
3073 [Chia-liang Kao <clkao@CirX.ORG>]
3075 *) The ab program in the src/support directory is now portable using
3079 *) Support directory is being compiled when the server is built
3082 *) The configure option --with-program-name has been added to allow
3083 developers to rename the executable at configure time. This also
3084 changes the name of the config files to match the executable's name.
3087 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3088 containing version numbers. [Martin Pool]
3090 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3091 Unix; access_log and error_log now created with these perms; non-
3092 Unix is unaffected [Jeff Trawick]
3094 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3095 Replaced more magic numbers with MD5_DIGESTSIZE.
3096 [William Rowe, Roy Fielding]
3098 *) Win32: Get mod_auth_digest compiling and added to the Windows
3099 build environment. Not tested and I'd be suprised if it
3100 actually works. [Bill Stoddard]
3102 *) Revamp the Win32 make environment. Makefiles have been removed and
3103 Apache.dsw created to bring together all the pieces. Create new file
3104 os/win32/BaseAddr.ref to define module base addresses (to prevent
3105 dll relocation at start-up).
3106 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3108 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3109 of the \015, \012, and \015\012 constants with macros.
3110 [Greg Ames <gregames@us.ibm.com>]
3112 *) Add ap_xlate_open() et al for translation of text between different
3113 character sets. The initial implementation requires iconv().
3116 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3117 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3119 *) CGI output is being timed out now.
3122 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3123 is used by the new apr file. There is no reason to create a new file
3124 with the same lifetime as the original file.
3127 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3128 module base addresses. This will help shooting seg faults
3129 in the field. [William Rowe <wrowe@lnd.com>]
3131 *) Update Apache on Windows documentation. Add new document
3132 describing how to compile Apache on Windows.
3133 [William Rowe <wrowe@lnd.com>]
3135 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3136 microseconds instead of seconds. Some storage leaks and other
3137 minor bugs in related code were fixed. [Jeff Trawick]
3139 *) Win32: First cut at getting mod_isapi working under 2.0
3140 [William Rowe <wrowe@lnd.com>]
3142 *) First stab at getting mod_auth_digest working under 2.0
3143 quick change summary:
3144 - moved the random byte generation (ap_generate_random_bytes) into APR
3145 - now uses ap_time_t
3146 - compiles and runs on linux
3148 [Brian Martin <bmartin@penguincomputing.com>]
3150 *) Win32: Move the space stripping of physical service names
3151 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3152 unresolved symbol. Add dependency checking to the
3153 CreateService call to ensure TCPIP and AFP (winsock) is started
3155 [William Rowe <wrowe@lnd.com>]
3157 *) Win32: Add code to perform latebinding on functions that may
3158 not exist on all levels of Windows where Apache runs. This
3159 is needed to allow Apache to start-up on Win95/98. All calls
3160 to non portable functions should be protected with
3161 ap_oslevel checks to prevent runtime segfaults.
3162 [William Rowe <wrowe@lnd.com>]
3164 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3166 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3168 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3169 This addresses PR 1623. Still need to address timing out runaway
3170 CGI scripts. [Bill Stoddard]
3172 *) Win32: Make ap_stat Windows 95/98 friendly
3173 [William Rowe <wrowe@lnd.com>]
3175 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3176 always fail. Need to initialise the dwOSVersionInfoSize member of the
3177 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3180 The patch also enhances ap_get_oslevel (and the associated enum) to
3181 handle selected service packs for NT4, and adds recognition for
3182 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3183 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3184 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3186 *) Get mod_rewrite building and running, and mod_status building for Win NT
3187 [Allan Edwards <ake@raleigh.ibm.com>]
3189 *) Patch to port mod_auth_db to the 2.0 api and also to support
3190 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3191 2.7.7. It should work with version 1 as well but I haven't tested it.
3192 [Brian Martin <bmartin@penguincomputing.com>]
3194 *) Get APR DSO code working under Windows. Includes cross platform
3196 [Tim.Costello@BTFinancialgroup.com]
3198 *) Fix some of the Windows APR time functions.
3201 *) FAQ changes related to tidying up historical documents on the web site.
3202 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3204 *) Move Windows DSO code into APR.
3207 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3208 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3209 at build time. At this point, the server will not compile on Windows because
3210 of the recent DSO commits. Fixing those next.
3211 [Bill Rowe & Bill Stoddard]
3213 *) Added error checking for file I/O APR routines.
3214 [Jon Travis <jtravis@covalent.net>]
3216 *) APR: Don't use the values of resolver error codes for the
3217 corresponding APR error codes. On Unix and Win32, return the
3218 proper APR error code after a resolver error. [Jeff Trawick]
3220 Changes with Apache 2.0a2
3222 *) Renamed the executable back to httpd on all platforms other
3226 *) Allow BeOS to survive restarts, log properly and a few
3227 small things it had problems with due to the way it setup
3228 users and groups. [David Reid]
3230 *) Get mod_rewrite working with APR locks
3231 [Paul Reder <rederpj@raleigh.ibm.com>]
3233 *) Actually remove the sempahore when the lock cleanup routine
3234 is called on BeOS. [David Reid]
3236 *) Clear hook registrations between reads of the config file.
3237 When DSOs are unloaded and re-loaded the old hook pointers may
3238 no longer be valid. This fix eliminates potential segfaults.
3239 [Allan Edwards <ake@raleigh.ibm.com>]
3241 *) Fix a problem with Sigfunc not being defined or bypassed
3242 if sigaction() wasn't found. [Jim Jagielski]
3244 *) Fix the locking mechanism on BSD variants. They now use fcntl
3245 locks. This allows the server to start and serve pages.
3248 *) First cut at getting the Win32 installer to work
3249 [William Rowe <wrowe@lnd.com>]
3251 *) Get htpasswd compiling under Windows
3252 [William Rowe <wrowe@lnd.com>]
3254 *) Change the log message for a bind() failure to show the
3255 interface and port number. [Jeff Trawick]
3257 *) Import the documentation from 1.3.12 and bring parts of it
3258 up-to-date with respect to the changes that have occurred
3262 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3263 now logged correctly on BeOS.
3266 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3267 Makefile.win includes the same user interface as the old
3269 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3271 *) Win32 exec now uses COMSPEC environment string for command
3272 shell path resolution.
3273 [William Rowe <wrowe@lnd.com>] PR#3715
3275 *) Win32: ap_connect() was not returning correct error condition
3277 [Allen Prescott <allen@clanprescott.com>]
3279 *) Win32: ap_open() was broken on Win9x because an NT-specific
3280 flag was passed to CreateFile. ap_puts() added an unnecessary
3282 [Jeff Trawick <trawick@us.ibm.com>]
3284 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3285 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3286 confusing ee/et name and made all extensions language/dialect
3287 rather than country reflecting. Changed example files to
3288 explicit reflect the ISO charset and added a few common
3289 ones to the example config [dirkx]
3291 *) Extend external module capability. To use this, you call
3292 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3295 *) Backported the various "default charset" fixes from 1.3.12,
3296 including the AddDefaultCharset directive. [Jim Jagielski]
3298 *) Added the capability to do ${ENVVAR} constructs in the
3299 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3300 it does this on a line by line basis; i.e. if the envvar
3301 expands to something with spaces you have to protect it
3302 by adding quotes around it (Unless of course you expect it
3303 to contains more than one argument. Alternatively you
3304 can compile it on a per token basis; which is what people
3305 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3306 hampers fancier hacks.
3307 [Dirk-Willem van Gulik]
3309 *) Changed the 'ErrorDocument' syntax in that it NO longer
3310 supports the asymetric
3312 ErrorDocument 301 "Some message
3314 Note the opening " quote, without a closing quote. It now
3315 has either the following syntaxes
3317 ErrorDocument XXX /local/uri
3318 ErrorDocument XXX http://valid/url
3319 ErrorDocument XXX "Some Message"
3321 The recognition heuristic is: if it has a space it
3322 is a message. If it has no spaces and starts with a /
3323 or is a valid URL then treat it that way. Otherwise it
3324 is assumed to be a message.
3326 This breaks backward compatibility but makes live a hell
3327 of a lot easier for GUI's and config file parsers.
3328 [Dirk-Willem van Gulik]
3330 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3331 syntax into a 'on' or 'off' syntax. As it currently is the
3332 only non nesting token which uses NO_ARGS and thus is an
3333 absolute pain for any config interface automation. This
3334 breaks backward compatibility. [Dirk-Willem van Gulik]
3336 *) Add ability to add external modules to the build process. This is
3337 done with --with-module=/path/to/module. Modules can only be added
3338 as static modules at this point.
3341 Changes with Apache 2.0a1
3343 *) Fix FreeBSD 3.3 core dump.
3344 Basically, ap_initialize() needs to get called before
3345 create_process(), since create_process() passes op_on structure
3346 to semop() to get a lock, but op_on isn't initialized until
3347 ap_initialize() calls setup_lock(). Here is a slight
3348 rearrangement to main() which calls ap_initialize() earlier...
3349 [Jeff Trawick <trawick@us.ibm.com>]
3351 *) Enable Apache to use sendfile/TransmitFile API
3352 [Bill Stoddard, David Reid, Paul Reder]
3354 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3358 *) Make file I/O and network I/O writev/sendv APIs consistent.
3359 Eliminate use of ap_iovec_t and use Posix struct iovec.
3360 Use seperate variable on ap_writev to set the number of iovecs
3361 passed in and number of bytes written.
3364 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3365 with ap_create_file_iol(). ap_create_file_iol() requires that
3366 the file be opened prior to the call using ap_open().
3369 *) Port mod_include and mod_cgi to 2.0
3370 [Paul Reder, Bill Stoddard]
3372 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3373 bytes_read/bytes_written is always valid (never -1). Plus
3374 some fixes to buff.c to correct problems introduced by the
3375 errno => ap_status_t changes a while back. Plus a fix to
3376 chunked encoding introduced right at the beginning of 2.0.
3379 *) Revamped UNIX build system to use autoconf and libtool.
3380 [Manoj Kasichainula, Sascha Schumann]
3382 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3384 *) More rigorous checking of Host: headers to fix security problems
3385 with mass name-based virtual hosting (whether using mod_rewrite
3386 or mod_vhost_alias).
3387 [Ben Hyde, Tony Finch]
3389 *) Add back support for UseCanonicalName in <Directory> containers.
3390 [Manoj Kasichainula]
3392 *) Added APLOG_STARTUP log type. This allows us to write an error
3393 message without any of the date and time information. As a part
3394 of this change, I also removed all of the calls to fprintf(stderr
3395 and replaced them with calls to ap_log_error using APLOG_STARTUP
3396 writing to stderr is no longer portable, because we don't direct
3397 stderr to the error log on all platforms.
3400 *) Convert error logging functions to take errno as an argument.
3401 This makes our error logs more portable, because some Windows API's
3402 don't set errno. This change allows us to still output a valid
3403 message on all of our platforms.
3406 *) mod_mime_magic runs in 2.0-dev now.
3407 [Paul Reder <rederpj@raleigh.ibm.com>]
3409 *) sendfile has been added to APR.
3410 [John Zedlewski <zedlwski@Princeton.EDU>]
3412 *) buff.c has been converted to no longer use errno.
3413 [Manoj Kasichainula]
3415 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3416 interface adaption to APR functions did it. [Martin Kraemer]
3418 *) Support DSOs properly on 32-bit HP-UX 11.0
3419 [Dilip Khandekar <dilip@cup.hp.com>]
3421 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3422 [Ralf S. Engelschall]
3424 *) Cleaned APR build environment integration and bootstrap APR
3425 automatically for developers from src/Configure.
3426 [Ralf S. Engelschall]
3428 *) Fixed building of src/support/htpasswd.c
3429 [Ralf S. Engelschall]
3431 *) When generating the Location: header, mod_speling forgot
3432 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3435 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3437 *) Change all pools to APR contexts. This is the first step to
3438 incorporating APR into Apache. [Ryan Bloom]
3440 *) Move "handler not found" warning message to below the check
3441 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3442 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3444 *) Support line-continuation feature in config.option file and
3445 allow the loading of multiple option sections at once via
3446 ``--with-option=<section1>,<section2>,...''
3447 [Ralf S. Engelschall]
3449 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3451 Changes with Apache MPM
3453 *) Use asynchronous AcceptEx() and a completion port to accept and
3454 dispatch connections to threads in Windows NT/2000.
3457 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3460 *) Implement the APACI --with-option facility
3461 (per default used the config.option file).
3462 [Ralf S. Engelschall]
3464 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3466 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3467 Replace pre_connection module call with a register_hook call and
3468 implement pre_connection as a hook. The intent is that these hooks will
3469 be extended to allow Apache to be multi-protocol, and also to allow the
3470 calling order to be specified on a per-hook/per-module basis.
3473 *) Implement mpm_* methods as "modules". Each method gets its own
3474 subdir in src/modules (eg: src/modules/prefork). Selection
3475 of method uses Rule MPM_METHOD. [Jim Jagielski]
3477 *) Port the hybrid server from the apache-apr repository as
3478 mpm_mpmt_pthread. [Manoj Kasichainula]
3480 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3481 amongst the unix MPMs.
3483 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3484 signal handling for the new world order. [Dean Gaudet]
3486 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3487 of alloc.c for now. [Dean Gaudet]
3489 *) Handle partial large writes correctly. [Ben Laurie]
3491 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3492 based on IP/port. [Ben Laurie]
3494 *) Port a bunch of modules to the new module structure.
3495 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3497 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3499 *) Basic restructuring to introduce the MPM concept; includes various
3500 changes to the module API... better described by
3501 docs/initial_blurb.txt. [Dean Gaudet]
3503 Changes with Apache pthreads
3505 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3506 buff operations (generally over a network).
3507 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3509 *) Created http_accept abstraction. Added 4 new functions (not exported):
3510 init_accept(), begin_accepting_requests(), get_request(),
3511 stop_accepting_requests() [Bill Stoddard]
3513 *) Fix to ap_rprintf call that allows mod_info to work properly.
3514 [James Morris <jmorris@intercode.com.au>]
3516 *) user and ap_auth_type fields were moved from connection_rec to
3517 request_rec. [Ryan Bloom]
3519 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3520 needed in a threaded server.
3522 *) Initial pthread implementation from from Dean's apache-nspr code.
3523 [Bill Stoddard, Ryan Bloom]
3526 Changes with Apache 1.3.9
3528 *) Remove bogus error message when a redirect doesn't set Location.
3529 Instead, use an empty string to avoid coredump if the error message
3530 was supposed to include a location. [Roy Fielding]
3532 *) Don't allow configure to include mod_auth_digest unless it is
3533 explicitly requested, even if the user asked for all modules.
3536 *) Translate module names to dll names for OS/2 so that they are no more
3537 than 8 characters long and have an extension of "dll" instead of "so".
3540 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3541 Fix test-compile check to check for randbyte instead of trand32.
3542 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3543 and tweak to make Amaya happier. [Ronald Tschalär]
3545 *) Ensure that the installed expat include files are world readable,
3546 just like the other header files. [Martin Kraemer]
3548 *) Fixed generated AddModule adjustments in APACI's `configure' script
3549 in order to allow (new) modules like mod_vhost_alias to be handled
3550 correctly (which was touched by the adjustments for mod_alias).
3551 [Ralf S. Engelschall]
3553 *) For binary builds, add -R flag to apachectl to work around the lack of
3554 an absolute path to the ./libexec directory where the libhttp.ep file
3555 is needed for SHARED_CORE architectures. [Randy Terbush]
3557 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3558 problem observed by some Win95/98 users where they get CGI script
3559 output sent to the console. [Bill Stoddard]
3561 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3562 routines are now called ap_base64* and are 'plain' (i.e., no
3563 pool access or anything clever). Inside util.c the routines acting
3564 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3565 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3566 now but deprecated. [dirkx]
3568 *) Clean up the base64 and SHA1 additions and make sure they are
3569 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3570 files. [Roy Fielding]
3572 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3573 checking. Allow compiling on VS 6.0. [Randy Terbush]
3575 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3577 *) Use TestCompile to search for the truerand library (rather than blindly
3578 assuming its existence). If it is not found, complain (but do not
3579 exit - yet). [Martin Kraemer]
3581 *) We forgot to add the new exported function names to
3582 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3584 *) Add description of -T command-line option to usage().
3585 [Ralf S. Engelschall]
3587 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3588 searched only AFTER libap has been searched, because libap needs
3589 some symbols from libos. [Martin Kraemer]
3591 *) Fix conflict with original mod_digest related to the symbol of the
3592 module dispatch list (which has to be unique for DSO and follow the
3593 usual conventions for the installation procedure).
3594 [Ralf S. Engelschall]
3596 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3597 for other platforms as well. [Martin Kraemer]
3599 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3600 types by AP_LONG and replace reference to renamed variable 'ubuf'
3601 by 'buffer'. [Martin Kraemer]
3603 Changes with Apache 1.3.8 [not released]
3605 *) Flush the output buffer immediately after sending an error or redirect
3606 response, since the result may be needed by the client to abort a
3607 long data transfer or restart a series of pipelined requests.
3608 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3610 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3611 [Ian Turner <iant@sequent.com>] PR#4735
3613 *) Local struct mmap in http_core.c conflicted with system structure
3614 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3616 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3617 [Ronald Tschalär <ronald@innovation.ch>]
3619 *) Fix a memory leak where the module counts were getting messed
3620 up across restarts. [David Harris <dharris@drh.net>]
3622 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3623 properly in mod_access.
3624 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3626 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3627 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3629 *) PORT: Support for compaq/tandem/com.
3630 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3632 *) Added SHA1 password encryption support to easy migration from
3633 Netscape servers. See support/SHA1 for more information.
3634 Caused the separation of ap_md5.c into md5, sha1 and a general
3635 ap_checkpass.c with just a validate_passwd routine. Added a
3636 couple of flags to support/htpasswd. Some reuse of the to64()
3637 function; hence renamed to ap_to64().
3638 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3640 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3641 with ASCII/EBCDIC conversions in "ident" query.
3642 [David McCreedy <McCreedy@us.ibm.com>]
3644 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3645 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3646 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3648 *) Fix SIGSEGV on some systems because the Vary fix below included
3649 a call to table_do with a variable argument list that was not
3650 NULL terminated. Replaced with better implementation. [Roy Fielding]
3652 Changes with Apache 1.3.7 [not released]
3654 *) The "Vary" response header field is now sanitised right before
3655 the header is sent back to the client. Multiple "Vary" fields
3656 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3657 "Vary: host, negotiate, host, accept-language") are reduced to
3658 single instances. This is a better solution than the force-no-vary
3659 one (which is still valid for clients that can't cope with Vary
3660 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3662 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3664 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3665 least on Linux and FreeBSD for now.
3668 *) Win32: More apache -k restart work. Restarts are now honored
3669 immediately and connections in the listen queue are -not- lost.
3670 This is made possible by the use of the WSADuplicateSocket()
3671 call. The listeners are opened in the parent, duplicated, then
3672 the duplicates are passed to the child. The original listen sockets
3673 are not closed by the parent across a restart, thus the listen queue
3675 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3677 *) Fix handling of case when a client has sent "Expect: 100-continue"
3678 and we are going to respond with an error, but get stuck waiting to
3679 discard the body in the pointless hope of preserving the connection.
3680 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3682 *) Fix 'configure' to work correctly with SysV-based versions of
3683 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3685 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3686 built-in values. Add "-e" option which works like -i but doesn't
3687 install the DSO; useful for editing httpd.conf with apxs. Fix
3688 editing code so that multiple invocations of apxs -a will not
3689 create duplicate LoadModule/AddModule entries; apxs can now be
3690 used to re- enable/disable a module. [Wilfredo Sanchez]
3692 *) Win32: Update the server to use Winsock 2. Specifically, link with
3693 ws2_32.lib rather than wsock32.lib. This gives us access to
3694 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3695 Win 95 users may need to update their TCP/IP stack to pick up
3696 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3697 [Bill Stoddard stoddard@raleigh.ibm.com]
3699 *) Win32: Redirect CGI script stderr (script debug info) into the
3700 error.log when CGI scripts fail. This makes Apache on Win32
3701 behave more like Unix.
3702 [Bill Stoddard stoddard@raleigh.ibm.com]
3704 *) Fixed `httpd' usage display: -D was missing.
3705 [Ralf S. Engelschall] PR#4614
3707 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3708 [Ralf S. Engelschall] PR#4561, PR#4562
3710 *) OS/2: Fix problem with accept lock semaphores where server would die with
3711 "OS2SEM: Error 105 getting accept lock. Exiting!"
3712 [Brian Havard] PR#4505
3714 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3715 [Randy Terbush <randy@covalent.net>]
3717 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3718 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3720 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3721 command potentially _is_ GCC. [Ralf S. Engelschall]
3723 *) Fix apxs build issues on AIX
3724 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3726 *) DocumentRoot Checking: Under previous versions, when Apache
3727 first started up, it used to do a stat of each DocumentRoot to
3728 see if it existed and was a directory. If not, then an error
3729 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3730 does not exist, you will get error messages in error_log. If
3731 the '-t' command line option is used (to check the configuration)
3732 the check of DocumentRoot IS performed. An additional command
3733 line option, '-T', has been added if you want to avoid the
3734 DocumentRoot check even when checking the configuration.
3737 *) Win32: The query switch "apache -S" didn't exit after showing the
3738 vhost settings. That was inconsistent with the other query functions.
3739 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3741 *) Win32: Changed behaviour of apache -k restart.
3742 Previously, the server would drain all connections in the stack's
3743 listen queue before honoring the restart. On a busy server, this
3744 could take hours. Now, a restart is honored almost immediately.
3745 All connections in Apache's queues are handled but connections in
3746 the stack's listen queue are discarded. Restart triggered by
3747 MaxRequestPerChild is unchanged.
3748 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3750 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3751 the accept loop. Good for a 5% performance boost. Cleaned up
3752 parent/child process management code.
3753 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3755 *) Added ceiling on file size for memory mapped files.
3756 [John Giannandrea <jg@meer.net>] PR#4122
3758 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3759 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3760 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3762 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3763 use this at least for Expat. [Ralf S. Engelschall]
3765 *) Allow .module files to specify libraries with Lib:.
3768 *) Allow SetEnvIf[NoCase] to test environment variables as well
3769 as header fields and request attributes. [Ken Coar]
3771 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3772 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3774 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3775 never accepted into any standard, and it opens up certain DoS
3776 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3778 *) TestCompile updated. We can now run programs and output the
3779 results during the Configure process. [ Jim Jagielski]
3781 *) The source is now quad (long long) aware as needed. Specifically,
3782 the Configure process determines the correct size of off_t and
3783 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3784 provides for the 'q' format qualifier (if quads are not available,
3785 'q' is silently "demoted" to long). [Jim Jagielski]
3787 *) When the username or password fed to htpasswd is too long, include the
3788 size limit in the error message. Also report illegal characters
3789 (currently only ':') in the username. Add the size restrictions
3790 to the man page. [Ken Coar]
3792 *) Fixed the configure --without-support option so it doesn't result in
3793 an infinite loop. [Marc Slemko]
3795 *) Piped error logs could cause a segfault if an error occured
3796 during configuration after a restart.
3797 [Aidan Cully <aidan@panix.com>] PR#4456
3799 *) If a "Location" field was stored in r->err_headers_out rather
3800 than r->headers_out, redirect processing wouldn't find it and
3801 the server would core dump on ap_escape_html(NULL). Check both
3802 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3803 if Location isn't set. [Doug MacEachern, Ken Coar]
3805 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3806 of the Expat 1.0.2 distribution. [Greg Stein]
3808 *) Replace regexec() calls with calls to a new API stub function
3809 ap_regexec(). This solves problems with DSO modules which use the regex
3810 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3812 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3813 environment variables can be set according to the protocol version
3814 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3816 *) Add DSO support for OpenStep (Mach 4.2) platform.
3817 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3819 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3820 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3822 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3823 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3825 *) Better DSO flags recognition on NetBSD platforms using ELF.
3826 [Todd Vierling <tv@pobox.com>] PR#4310
3828 *) Always log months in english format for %t in mod_log_config.
3829 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3831 *) Support for server-parsed and multiview-determined ReadmeName and
3832 HeaderName files in mod_autoindex. Removed the restriction on
3833 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3834 routines will deal with the access issues. (It's now possible to
3835 have {site|group|project|customer|...} wide readmes and headers.)
3836 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3839 *) When stat() fails, don't assume anything about the contents of
3840 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3842 *) It's OK for a semop to return EINTR, just loop around and try
3843 again. [Dean Gaudet]
3845 *) Fix configuration engine re-entrant hangups, which solve a
3846 handful of problems seen with mod_perl <Perl> configuration sections
3847 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3849 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3850 by default when building with APACI; allow for platform-specific
3851 variable defaults in configure. [Wilfredo Sanchez]
3853 *) Do setgid() before initgroups() in http_main; some platforms
3854 zap the grouplist when setgid() is called. This was fixed in
3855 suexec earlier, but the main httpd code missed the change.
3856 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3858 *) Add recognition of .tgz as a gzipped tarchive.
3859 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3861 *) mod_include's fsize/flastmod should allow only relative paths, just
3862 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3864 *) OS/2: Add support for building loadable modules using DLLs.
3867 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3870 *) Fix minor but annoying bug with the test for Configuration.tmpl
3871 being newer than Configuration so that it is less likely to fail
3872 when using APACI and shadow sources. [Wilfredo Sanchez]
3874 *) PORT: Add initial support for Mac OS (versions 10.0 and
3875 greater). Use Mac OS X Server layout for now. Clean up dyld code
3876 in unix/os.c, and don't install the dyld error handlers, which
3877 are no longer needed in Mac OS. [Wilfredo Sanchez]
3879 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3880 locations to appropriate ones for user-built (as opposed to
3881 system) installs. [Wilfredo Sanchez]
3883 *) Modify mod_autoindex's handling of AddDescription so that the
3884 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3886 *) Add functionality to the install-bindist.sh script created by
3887 binbuild.sh to use tar when copying distribution files to the
3888 serverroot. This allows upgrading an existing installation
3889 without nesting the new distribution in the old.
3891 install-bindist.sh now detects the local perl5 path to install
3892 apxs and dbmmanage with proper path to perl interpreter.
3894 Add an install-binsupport target which copies the source files
3895 for apxs and dbmmanage to bindist to allow these scripts to
3896 be properly installed relative to the destination serverroot.
3897 [Randy Terbush, Covalent Technologies, randy@covalent.net]

4006 by "Peter 'Luna' Altberg <peter@altberg.nu>" and PR#3422
4007 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
4009 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
4012 *) Correct an apparent typo: on the Windows and MPE platforms, the
4013 htpasswd utility was limiting passwords to only 8 characters.
4016 *) EBCDIC platforms: David submitted patches for two bugs in the
4017 MD5 digest port for EBCDIC machines:
4018 a) the htdigest utility overwrote the old contents of the digest file
4019 b) the Content-MD5 header value (ContentDigest directive) was wrong
4020 when the returned file was not converted from EBCDIC, but was a
4021 binary (e.g., image file) in the first place.
4022 [David McCreedy <mccreedy@us.ibm.com>]
4024 *) support/htpasswd now permits the password to be specified on the
4025 command line with the '-b' switch. This is useful when passwords
4026 need to be maintained by scripts -- particularly in the Win32
4027 environment. [Ken Coar]
4029 *) Win32: Win32 multiple services patch. Added capability to install and
4030 run multiple copies of apache as individual services.
4033 apache -n apache1 -i -f c:/httpd.conf
4034 Installs apache as service 'apache1' and associates c:/httpd.conf
4037 Starts apache1 service.
4039 Stops apache1 service
4042 apache -n apache2 -i
4043 Installs apache as service 'apache2'. httpd.conf is located under
4044 the default server root (/apache/conf/httpd.conf).
4046 Starts apache2 service.
4049 apache -n apache3 -i -d c:/program files/apache

4055 Restart apache2 service
4057 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
4059 *) Correct the signed/unsigned character handling for the MD5 routines;
4060 mismatches were causing compilation problems with gcc -pedantic and
4061 in the TPF cross-compilation. [Ken Coar]
4063 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4064 a roughly 5 fold speed up. [Brian Havard]
4066 *) proxy ftp: instead of using the hardwired string "text/plain" as
4067 a fallback type for files served by the ftp proxy, use the
4068 ap_default_type() function to determine the configured type.
4069 This allows for special configurations like
4070 <Directory proxy:ftp://some.host>
4071 DefaultType gargle/blurb
4073 Additionally, add the Content-Encoding: header to FTP proxy replies
4074 when the encoding is defined (by the AddEncoding directive).
4075 Because it was missing, it was almost impossible to browse compressed
4076 files using the FTP proxy (works now perfectly in Communicator).
4077 The ftp proxy now also returns the Date: and Server: header lines (if not
4078 much else... This code is "somewhat" broken) like normal requests do.
4081 *) Be more smart in APACI's configure script when determining the UID/GID
4082 for User/Group directives and use the determined UID/GID to initialize
4083 the permissions on the proxycachedir.
4084 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4086 *) Changed the forking-prior-to-cleanup in the proxy module to first
4087 check wether it actually needs to collect garbage. This reduces
4088 the number of fork()s from one/request to just the odd one an hour.
4089 [Dirk-Willem van Gulik]
4091 *) Added proxy, auth and header support to src/support/ab.c. Added a

4098 *) Add support for DSO module compilation on BSD/OS 3.x.
4099 [Randy Terbush, Covalent Technologies]
4101 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
4102 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
4103 option) were substituted with $(TARGET).conf, etc. Same for other strings
4104 with dots where the dot wasn't matched as plain text.

4112 Changes with Apache 1.3.6
4114 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
4116 Changes with Apache 1.3.5 [not released]
4118 *) M_INVALID needed a value within the scope of METHODS so that unknown
4119 methods can be access controlled. [Roy Fielding] PR#3821
4121 *) Added PassAllEnv; makes server's entire environment available
4122 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4124 *) ap_uuencode() always added two trailing '='s and encoding of
4125 8 bit characters on a machine with signed char may produced
4126 incorrect results. Additionally ap_uuencode() should now
4127 work correctly on EBCDIC platforms.
4128 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4130 *) WIN32: Binary installer now runs the configuration DLL before
4131 the reboot prompt (which is only given if MSVCRT.DLL system
4132 DLL is new or updated). This should avoid the configuration
4133 directory being empty after installation. [Paul Sutton]
4134 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

4137 and stop Apache as a console application and to uninstall
4138 the Apache service on NT. [Paul Sutton] PR#3741
4140 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
4142 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
4143 have been reported with flock() locking (probably related to kernel
4144 version). [Dean Gaudet] PR#2723, 3531
4146 *) Using APACI, the main config file (usually httpd.conf) was
4147 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez

4157 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4158 for 8-bit safeness. [Dean Gaudet]
4160 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4161 because SPARCs have a small machine-specific maximum size for the Global
4162 Offset Table which is often exceeded when compiling one of the larger
4163 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4165 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
4166 DSO/DLL section because it's a directive from mod_status and isn't
4167 available before the DLL of mod_status is loaded.

4180 [John Tobey <jtobey@banta-im.com>] PR#3983
4182 *) Let APACI's configure script correctly complain for unknown --enable-XXX
4183 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
4185 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
4186 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
4187 possible buffer overflows. [Ralf S. Engelschall]
4189 *) Remove no longer used non-API function ap_single_module_init().
4190 [Ralf S. Engelschall]
4192 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4195 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4196 to make platform installations easier. [Wilfredo Sanchez]
4198 *) In configure, do not append the target name to the directory path if
4199 the path already contains "apache". [Ralf S. Engelschall]
4201 *) SIGPIPE is now ignored by the server core. The request write routines
4202 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4203 correctly check for output errors and mark the connection as aborted.
4204 Replaced many direct (unchecked) calls to ap_b* routines with the
4205 analogous ap_r* calls. [Roy Fielding]
4207 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4208 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4209 Furthermore map lookups for non-existent keys are now cached as well.
4210 Additionally "txt" maps are now parsed with simple string functions
4211 instead of using ap_pregcomp(). As a side effect a bug that prevented
4212 the usage of keys containing the "," character was fixed.
4213 The changes drastically improve the performance when large rewrite maps
4215 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4217 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4218 other than GET, and const'd the definition of method in request_rec.
4221 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
4223 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4224 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4226 *) Add %V to mod_log_config, this logs the hostname according to the
4227 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4228 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4230 *) Add support for \n and \t to mod_log_config, can be used to produce
4231 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4233 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4235 *) Added informative error messages for failed munmap() and fseek() calls
4236 in http_core.c. [John Bley, Roy Fielding]
4238 *) Added some informative error messages for some failed malloc()
4239 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4241 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4242 is removed. This allows <Directory proxy:*> directives to work and
4243 prevents invalid requests from killing the process.
4244 [Brian Havard <brianh@kheldar.apana.org.au>]
4246 *) Reorganised FAQ document.
4247 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
4249 *) src/support/: The ApacheBench benchmark program was overhauled by
4250 David N. Welton: you can now have it generate an HTML TABLE, presumably
4251 for integration into other HTML sources. David updated the ab man page
4252 as well and added some missing descriptions. Thanks!
4253 [David N. Welton <davidw@prosa.it>]
4255 *) Win32: The filename validity checker now allows filenames containing
4256 characters in the range 0x80 to 0xff (for example accented characters).
4257 [Paul Sutton] PR#3890
4259 *) Added conditional logging based upon environment variables to
4260 mod_log_config. mod_log_referer and mod_log_agent
4261 are now deprecated. [Ken Coar]
4263 *) Allow apache acting as a proxy server to relay the real
4264 reason of a failure to a client rather than the "internal
4265 server error" it does currently. The general exposure mechanism
4266 can be triggered by any module by setting the "verbose-error-to"
4267 note to "*"; this allows more than just proxy errors to be exposed.
4268 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4270 *) Moved man pages for ab and apachectrl to section 8.
4271 [Wilfredo Sanchez, Roy Fielding]
4273 *) Added -S option to install.sh so that options can be passed to
4274 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4276 *) Tweak modules Makefile generated by Configure so that it handles
4277 the test case of no modules being selected. [chaz@reliant.com]
4279 *) Added a <LimitExcept method ...> sectioning directive that allows
4280 the user to assign authentication control to any HTTP method that
4281 is *not* given in the argument list; i.e., the logical negation
4282 of the <Limit> directive. This is particularly useful for controlling
4283 access on methods unknown to the Apache core, but perhaps known by
4284 some module or CGI script. [Roy Fielding, Tony Finch]
4286 *) Prevent apachectl from complaining if the PIDFILE exists but
4287 does not contain a process id, as might occur if the server is
4288 being rapidly restarted. [Wilfredo Sanchez]
4290 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4292 *) Entity tag comparisons for If-Match and If-None-Match were not being
4293 performed correctly -- weak tags might cause false positives. Also,
4294 strong comparison wasn't properly enforced in all cases.
4295 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4297 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4300 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4301 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4303 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4304 to util.c for parsing an HTTP header field value to extract the next
4305 list item, taking into account the possible presence of nested comments,
4306 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4307 insignificant whitespace and lowercases non-quoted tokens.
4308 [Roy Fielding] PR#2065
4310 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4311 code different from 500. This allows the proxy to, e.g., return
4312 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4314 *) Fix ordering of language variants for the case where the traditional
4315 negotiation algorithm is being used with multiple language variants
4316 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4318 *) Do not round the TCN quality calculation to 5 decimal places,
4319 unlike RFC 2296, because the calculation might need 12 decimal places
4320 to get the right result. [Roy Fielding]
4322 *) Remove unused code to disable transparent negotiation when
4323 negotiating on encoding only, as we now handle encoding too
4324 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4325 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4326 some debugging statements within mod_negotiation. [Koen Holtman]
4328 *) Fixed a rare memory corruption possibility in mod_dir if the index
4329 file is negotiable and no acceptable variant can be found.
4330 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4332 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4333 searching the Win32 registry for script interpreters.
4336 *) Win32: The compiled-in default filename for the error log is now
4337 error.log, which matches the default in the distributed httpd.conf.
4340 *) Win32: Any error messages from -i or -u command line options are now
4341 displayed on the console output rather than sent to the error log.
4342 Also the "Running Apache..." message is not output unless Apache is
4343 going to serve requests. [Paul Sutton]
4345 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4346 and use a private significator ('$apr1$') to mark passwords as
4347 being smashed with our own algorithm. Also abstract the password
4348 checking into a new ap_validate_password() routine. [Ken Coar]
4350 *) Win32: The filename validity checker now allows "COM" but refuses
4351 access to "COM1" through "COM4". This allows filenames such
4352 as "com.name" to be served. [Paul Sutton] PR#3769.
4354 *) BS2000: Adapt to the new ufork() system call interface which will
4355 make subtasking easier on the OSD/POSIX mainframe environment.
4358 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4359 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4361 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4362 use `.db' instead of `.pag' not only for FreeBSD, but also when
4363 the NDBM library looks like Berkeley-DB based.
4364 [Ralf S. Engelschall] PR#3773
4366 *) Add ability to handle DES or MD5 authentication passwords.
4367 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4369 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4371 *) SECURITY: Avoid some buffer overflow problems when escaping
4372 quoted strings. (This overflow was on the heap and we believe
4373 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4375 *) Let src/Configure be aware of CFLAGS options starting with plus
4376 signs as it's the case for the HP/UX compiler.
4377 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4379 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4380 and check to see if the tar we wind up with supports '-h'.
4381 [Jim Jagielski] PR#3671
4383 *) A consistent and conservative style for all shell scripts has been
4384 implemented. Basically, all shell string tests use the traditional
4385 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4386 to protect against bare null variable strings (ie: wrapping both
4387 sides with double quotes and prepending 'x'). 'x' was chosen
4388 because it's more universal and hopefully easier for old shell
4389 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4392 *) The status module now prints out both the main server generation as
4393 well as the generation of each process. Also, the vhost info is
4394 printed with '?notable'. [Jim Jagielski]
4396 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4397 and this makes its functions available to things in src/support.
4400 Changes with Apache 1.3.4
4402 *) Renamed macros status_drops_connection to ap_status_drops_connection
4403 and vestigial scan_script_header to ap_scan_script_header_err,
4404 mostly for aesthetic reasons. [Roy Fielding]
4406 *) The query switch "httpd -S" didn't exit after showing the
4407 vhost settings. That was inconsistent with the other query functions.
4410 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4411 filename to the end of the STANDARD_MODULE_STUFF. Its
4412 presence at the beginning prevented reporting of the filename
4413 for modules compiled before 1 January 1999. [Ken Coar]
4415 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4416 to detect and prevent access to special DOS device file names.
4417 [Paul Sutton, Ken Parzygnat]
4419 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4420 and Makefile_win32_debug.txt (debug build) that work on Win95.
4421 Run each of the following from the src directory:
4422 nmake /f Makefile_win32.txt # compiles normal build
4423 nmake /f Makefile_win32.txt install # compiles and installs
4424 nmake /f Makefile_win32.txt clean # removes compiled junk
4425 nmake /f Makefile_win32_debug.txt # compiles debug build
4426 nmake /f Makefile_win32_debug.txt install
4427 nmake /f Makefile_win32_debug.txt clean
4430 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4431 to build binary distributions. [Lars Eilebrecht]
4433 *) IndexOptions SuppressColumnSorting only turned off making
4434 the column headers anchors; you could still change the display
4435 order by manually adding a '?N=A' or similar query string to the
4436 URL. Now SuppressColumnSorting locks in the sort order so
4437 it can't be overridden this way. [Ken Coar]
4439 *) Added IndexOrderDefault directive to supply a default sort order
4440 for FancyIndexed directory listings. [Ken Coar] PR#1699
4442 *) Change the ap_assert macro to a variant that works on all platforms.
4443 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4445 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4446 search for an underscore on dlsym() (as it's already the case
4447 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4449 *) Small fix for mod_env.html: The module was documented as to be _not_
4450 compiled into Apache per default, although it _IS_ compiled into
4451 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4453 *) Instead of fixing a bug in the generation procedure for config.status (a
4454 backslash was missing) we remove the bug together with it's complete
4455 context because the special cases of the past can now no longer occur
4456 because of the recent magic for the --with-layout default.
4457 [Ralf S. Engelschall] PR#3590
4459 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4460 making sure the src/support/ tools are _forced_ to be build last (they
4461 depend on other libraries).
4462 [Markus Theissinger <markus.theissinger@gmx.de>]
4464 *) Fix installation procedure: Now that os-inline.c is actually used (a
4465 recently fixed bug prevented this) we need to also install os-include.c
4466 in addition to os.h into the PREFIX/include/ location or building of
4467 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4469 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4470 allow us to distinguish between a garbled DSO (or even a file which isn't
4471 an Apache module DSO at all) and a DSO which doesn't match the current
4472 Apache API. [Ralf S. Engelschall] PR#3152
4474 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4475 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4476 match case insensitive (this especially avoids nasty patterns like
4477 `[tT][eE][sS][tT]'). Second two additional internal map functions
4478 `escape' and `unescape' were added which can be used to escape/unescape
4479 to/from hex-encodings in URLs parts (this is especially useful in
4480 combination with map lookups).
4481 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4483 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4484 forgotten (because it was a macro) in the symbol renaming process.
4485 [Ralf S. Engelschall]
4487 *) Fix some inconsistencies related to the scopes of directives. The only
4488 user visible change is that the directives `UseCanonicalName' and
4489 `ContentDigest' now use the (more correct) `Options' scope instead of
4490 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4492 *) Using DSO, the Server token was being mangled. Specifically, the
4493 module's token was being added first before the Apache token. This
4494 has been fixed. [Jim Jagielski]
4496 *) Major overhaul of mod_negotiation.c, part 2.
4497 - properly handle "identity" within Accept-Encoding.
4498 - allow encoded variants in RVSA negotiation and let them appear in
4499 the Alternates field using the non-standard "encoding" tag-list.
4500 - fixed both negotiation algorithms so that an explicitly accepted
4501 encoding is preferred over no encoding if "identity" is not
4502 included within Accept-Encoding.
4503 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4504 of large substring sequences.
4505 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4508 *) Major overhaul of mod_negotiation.c, part 1.
4509 - cleanups to mod_negotiation comments and code structure
4510 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4511 support for everything in the upcoming HTTP/1.1
4512 revision (draft-ietf-http-v11-spec-rev-06.txt).
4513 - language tag matching also handles tags with more than 2
4515 - empty Accept, Accept-Language, Accept-Charset headers are
4516 processed correctly; previously an empty header would make all
4517 values acceptable instead of unacceptable.
4518 - allowed for q values in Accept-Encoding
4519 - added support for transparent content negotiation (rfc2295 and
4520 rfc2296) (though we do not implement all features in these drafts,
4521 e.g. no feature negotiation). Removed old experimental version.
4522 - implemented 'structured entity tags' for better cache correctness
4523 (structured entity tags ensure that caches which can deal with Vary
4524 will (eventually) be updated if the set of variants on the server
4526 - this involved adding a vlist_validator element to request_rec
4527 - this involved adding the ap_make_etag() function to the global API
4528 - modified guessing of charsets used by Apache negotiation algorithm
4529 to guess 'no charset' if the variant is not a text/* type
4530 - added code to sort multiviews variants into a canonical order so that
4531 negotiation results are consistent across backup/restores and mirrors
4532 - removed possibility of a type map file resolving to another type map
4533 file as its best variant
4534 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4536 *) RFC2396 allows the syntax http://host:/path (with no port number)
4537 but the proxy disallowed it (ap_proxy_canon_netloc()).
4538 [David Kristol <dmk@bell-labs.com>] PR#3530
4540 *) When modules update/modify the file name in the configfile_t structure,
4541 syntax errors will report the updated name, not the original one.

4544 *) Correct some filename case assumptions from WIN32 to
4545 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4547 *) For %v log ServerName regardless of the UseCanonicalName
4548 setting (similarly for %p). [Dean Gaudet]
4550 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4551 rather late (too late for some invocations of TestCompile).
4552 This improves the make environment available to TestCompile and
4553 the *.module scripts. [Martin Kraemer]
4555 *) The hashbang emulation code in ap_execve.c would interpret
4556 #!/hashbang/scripts correctly, but failed to fall back to a
4557 standard shell for scripts which did NOT start with #!
4558 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4560 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4563 *) Update APXS manual page: some -q option arguments were missing
4564 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4566 *) Cleanup the command line options: `-?' was documented to show
4567 the usage list but does it with an error because `?' is not a valid
4568 command. OTOH a lot of users expect `-h' to print such a usage list and
4569 instead are annoyed for ages by our huge unreadable list of directives.
4570 So we now changed the command line options this way:
4572 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4573 very similar to the popular linker option.
4575 Intent: while -l gives the small list of modules, -L now gives the
4576 large list of directives implemented by these modules. This is also
4577 consistent with -v (short version info) and -V (large version info).
4579 Intent: it's now the expected option ;-)
4580 The manual page was adjusted accordingly.
4581 [Ralf S. Engelschall] PR#2714
4583 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4584 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4586 *) Removed recently introduced bugs and disfigurements in APACI:
4587 o fixed argument line processing: using $args was broken: It was not
4588 initialized and using args="$args $apc_option" and even args="$args
4589 \"$apc_option\"" fails in the second processing round for any arguments
4590 containing whitespaces. The only correct way is to use the construct
4591 "$@" (but not possible here) or iterate _both_ times over the implicit
4592 argument line (no argument to for-loop) which is what we now use.
4593 o make --with-layout=Apache the default without creating
4594 redundancy (copying the --with-layout block in the argument parsing
4595 loop). We achieve this by using the "$@" construct together with the
4596 `set' command to prepend --with-layout=Apache to the command line in
4597 case --with-layout is not used.
4598 o fixed auto-suffix handling now that config.layout exists.
4599 Paths which are auto-suffixed are marked with a trailing plus sign in
4600 config.layout and every path now can be marked this way (not only the
4601 four paths for which we do it currently). Additionally the suffix is
4602 no longer a static one. Instead it's now `/<target>' where <target> is
4603 the argument of the --target option or per default `httpd'.
4604 o allow also tabs (and only spaces) where we match whitespaces
4605 o various fixes and cleanups related to used shell coding style
4606 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4607 o trimmed output of --help to fit into 80 columns
4608 [Ralf S. Engelschall]
4610 *) Added two new core API functions, ap_single_module_configure() and
4611 ap_single_module_init(), which are now used by mod_so to configure a module
4612 after loading. [Ralf S. Engelschall]
4614 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4615 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4616 of ap_config.h to allow serialized accept for multiport listens.
4617 [Roy Fielding, Curt Sampson] PR#3120
4619 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4620 of ap_config.h that would skip several defines if DEFAULT_GROUP
4621 was overridden. [Roy Fielding]
4623 *) PORT: The I86 version of DGUX has support for strncasecmp and
4624 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4626 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4627 defined before it might be used. [Victor Khimenko]
4629 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4630 [Tom Serkowski <tks@bsdi.com>] PR#3453
4632 *) Make generation of src/Configuration.apaci more robust: It failed to
4633 differenciate between modules when one module name was a postfix of
4634 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4635 just XXX (think about totally non-standard names like "apache_ssl", too).
4636 [Ralf S. Engelschall] PR#3380
4638 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4639 since 1.3b7) and make whitespace handling more robust (it failed horrible
4640 when whitespaces were present in the arguments of -D options).
4641 [Ralf S. Engelschall] PR#3240
4643 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4644 creates an external package shadow tree in DIR before the local build
4645 shadow tree is generated under DIR. This way one can have the extracted
4646 Apache distribution tree read-only on NFS or CDROM and still build Apache
4647 from these sources. An automatically triggered VPATH-like mechanism is
4648 provided through the TOP variable, too.

4651 *) Fix negotiation so that a Vary response header is correctly
4652 generated when, for a particular dimension, variants only vary
4653 in having or not having a value for that dimension. [Paul Sutton]
4655 *) Fix negotiation so that we prefer an encoded variant over an
4656 unencoded variant if the user-agent explicitly says it can
4657 accept that encoding. Previously we always preferred the unencoded
4659 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4661 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4662 and the usage page was inconsistent with the functionality and manpage.
4663 [Ralf S. Engelschall]
4665 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4666 They can occur multiple times and their arguments (`xxx') are passed AS
4667 IS to the compiler/linker command. [Ralf S. Engelschall]
4669 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4670 procedure of mod_rewrite: very long keys were truncated.
4671 [Ralf S. Engelschall]
4673 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4674 identifier, currently "Apache" and "GNU" are pre-defined in the file
4675 config.layout. Custom layouts are possible by using FILE:ID as the
4676 argument where the layout ID is taken from FILE.
4678 The config.layout file consists of <Layout ID>..</Layout> sections
4679 where inside those sections "path_variable: path_value" pairs can be
4680 specified. These lines are converted to path_variable='path_value'.
4682 *) Add a DefaultLanguage directive so that files missing a language
4683 extension (e.g., .fr, .de) can be labelled as being some other
4684 default language. DefaultLanguage can appear in <Directory> and
4685 <Files> containers as well as .htaccess files. [Paul Sutton]
4688 *) Fix TARGET configuration when configuring and installing using
4689 APACI configure. TARGET now defines the basename of the configuration
4690 file, startup script, manual page, etc. log_error_core() now reports
4691 the server binary name given by argv[0]. TARGET can now also be defined
4692 with --target=TARGET parameter passed to APACI configure.
4693 [Ralf Engelschall, Randy Terbush]
4695 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4696 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

4716 and a redirect at the same time. [Lars Eilebrecht]
4718 *) Fallback to native compilers for IRIX-32 platform. It seems that
4719 a gcc 2.8.1 compiled apache is logging client addresses with all
4720 bits set (255.255.255.255). This is the second such problem caused
4721 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4724 *) Updated mime.types to reflect current Internet media types
4725 and include a URL to the registry.

4732 used to set the document root directory (DOC_ROOT) and the suexec
4733 logfile (LOG_EXEC), respectively. Additionally the --layout option
4734 was changed to show more information about the suEXEC setup.

4742 modules, Limit, and Script directives. That includes PATCH,
4743 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
4744 Improved mod_actions.c so that it can use any of the methods

4772 since it often includes file path info. Enable sending of error-notes
4773 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
4775 *) http_config.c would respond with 501 (Method Not Implemented) if a
4776 content type handler was specified but could not be found, which
4777 should have been a 500 response. Likewise, mod_proxy.c would responsd
4778 with a 501 if the URI scheme is unrecognized instead of the correct
4779 response of 403 (Forbidden). [Roy Fielding]

4785 unavailable, an empty string was printed which was 2 bytes short.
4786 The size and description columns were therefore not aligned correctly.

4794 scoreboard file and avoid a string copy (as well as allow some
4795 further future enhancements). [Harrie Hazewinkel
4796 <harrie.hazewinkel@jrc.it>]
4798 *) Add APACI --permute-module=foo:bar option which can be used to
4799 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4800 in the Configuration[.apaci] file. Two special and important variants are
4801 supported for the option argument: first BEGIN:foo which permutes module
4802 mod_foo with the begin of the module list, i.e. it `moves' the module to
4803 the begin of the list (gives it lowest priority). And second foo:END
4804 which permutes mod_foo with the end of the module list, i.e. it `moves'
4805 the module to the end of the list (gives it highest priority).

4821 *) Properly handle & allow "nul" and ".*/null" in AccessConfig and

4876 Changes with Apache 1.3.3
4878 *) Added a complete implementation of the Expect header field as

4880 response when we already know the final status, which is mighty
4881 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4883 *) Remove extra trailing whitespace from the getline results as part
4884 of the protocol processing, which is extra nice because it works
4885 between continuation lines, is almost no cost in the normal case
4886 of no extra whitespace, and saves memory. [Roy Fielding]
4888 *) Added new HTTP status codes and default response bodies from the
4889 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
4890 HTTP Extension Framework (510) specifications. Did not add the
4891 WebDAV 424 and 425 codes because they are bogus. We don't use any
4892 of these codes yet, but they are now available to 3rd-party modules.

4965 <steve.cameron@compaq.com>]
4967 *) Reconstructed the loop through multiple htaccess file names so
4968 that missing files are not confused with unreadable files.
4971 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
4972 errno on an error, which leads to one error being mistaken for
4973 another when reading non-existent .htaccess files.
4976 *) OS/2: The new header tests get things right, need to update
4977 ap_config.h. [Brian Havard]

4996 *) Fix bug in ap_remove_module(), which caused problems for dso's
4997 who were the top_module. [Doug MacEachern]
4999 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
5000 mod_auth_db to both be friendly to users who wants to use this version
5001 and to avoid problems under platforms where only version 2.x is present.
5002 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
5004 *) When using ap_log_rerror(), make the error message available to the
5005 *ERROR_NOTES envariables by default. [Ken Coar]
5007 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
5008 You now must define a BS2000Account name for the server User.
5009 This has fewer security implications than the old approach.
5012 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
5013 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
5014 platform to make the braindead HPUX linker happy. Notice, for the module
5015 DSOs we don't have to use this, because these are loaded manually (and
5016 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
5018 *) Remove 64 thread limit on Win32.

5025 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
5027 *) Make PrintPath work generically instead of having one version
5028 strictly for OS/2. [Jim Jagielski, Brian Havard]
5030 *) Fix the recently introduced C header file checking: We now use the C
5031 pre-processor pass only (and no longer the complete compiler pass) to
5032 determine whether a C header file exists or not. Because only this way
5033 we're safe against inter-header dependencies (which caused horrible
5034 portability problems). The only drawback is that we now have a CPP
5035 configuration variable which has to be determined first (we do a similar
5036 approach as GNU Autoconf does here). When all fails the user still has
5037 the possibility to override it manually via APACI or src/Configuration.
5038 As a fallback for the header check itself we can directly check the
5039 existance of the file under /usr/include, too.
5040 [Ralf S. Engelschall] PR#2777
5042 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
5043 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
5044 ap_private_extern defined to hide symbols that conflict with loaded
5045 dynamic libraries on the NEXT and RHAPSODY platforms.

5070 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
5071 platform, because it's only supported under version 4.0 and higher. But
5072 because our GuessOS is still unaware of Digital UNIX versions and the
5073 -msym is just to optimize the DSO statup time a little bit it's safe and
5074 best when we leave it out now. [Ralf S. Engelschall] PR#2969
5076 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
5077 functions: First all three functions no longer fail on strings containing
5078 "%" chars and second ap_log_printf() no longer does a double-formatting
5079 (instead it directly passes through the message to be formatted to the
5080 real internal formatting function). [Ralf S. Engelschall] PR#2941
5082 *) Allow "Include" directives anywhere in the server config
5083 files (but not .htaccess files). [Ken Coar] PR#2727
5085 *) The proxy was refusing to serve CONNECT requests except to
5086 port 443 (https://) and 563 (snews://). The new AllowCONNECT
5087 directive allows the configuration of the ports to which a
5088 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5090 *) mod_expires will now act on content that is not sent from a file
5091 on disk. Previously it would never add an Expires: header to
5092 any response that did not come from a file on disk; the only
5093 case where it still doesn't (and can't) add one for that type of
5094 content is if you are using a modification date based setting.
5095 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
5097 *) Problems encountered during .htaccess parsing or CGI execution
5098 that lead to a "500 Server Error" condition now provide explanatory
5099 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
5102 *) Add NameWidth keyword to IndexOptions directive so that the
5103 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
5106 *) Recognize lowercase _and_ uppercase `uname' results under
5107 SCO OpenServer. [David Coelho <drc@ppt.com>]
5109 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5110 a common problem of (mis-administrated?) IIS servers, make the apache
5111 proxy immune to these errors (and ignore the duplicates, but log
5112 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5114 *) The <IfModule and <IfDefine block starting directives now only
5115 allow exactly one argument. Previously, the optional negation
5116 character '!' could be separated by whitespace without a syntax
5117 error being reported, albeit defeating the IfModule functionality
5118 (enclosed directives would ALWAYS be executed). By using the
5119 stricter syntax, these hard-to-track errors can be avoided.
5122 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5123 cause the standalone FancyIndexing directive to logically OR
5124 into any existing IndexOptions settings rather than wiping
5125 them out. [Ken Coar]
5127 *) Changes in ftp proxy: make URL parsing simpler by using the
5129 + Add display of the "current directory" in cases where it's
5130 different from the supplied path (e.g., ftp://user@host/ lives
5131 in /home/user, not in /, therefore clicking on "../" in the
5132 starting directory might send us to /home/).
5133 + When ftp login fails, (esp. when a user name was part of the
5134 URL already), we now return [401 Unauthorized ] to allow the
5135 browser to pop up an authorization dialog. This makes passwords
5136 slightly less visible (they don't appear in the regular log files)
5137 and implements a functionality that other www proxy servers
5141 *) Triggered by the recent "Via:" header changes, the proxy module would
5142 dump core for replies with invalid headers (e.g., duplicate
5143 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5144 core dump is avoided. Also, broken replies are not cached.
5145 [Martin Kraemer] PR#2914
5147 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
5148 plop gmon.out profile data for each child [Doug MacEachern]
5150 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
5151 config.status script to be immune against arguments with whitespaces.
5152 [Yves Arrouye <yves@apple.com>] PR#2866
5154 *) Replace the inlined information grabbing stuff for the configuration
5155 adjustment feature (no --without-confadjust) with calls to a new helper
5156 script `buildinfo.sh' which is both more flexible and already proofed to
5157 be more robust against platform differences. This mainly fixes the
5158 recently occured ``sed: command garbled: ...'' problems.
5159 [Ralf S. Engelschall] PR#2776, PR#2848
5161 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
5162 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
5163 without complains after we recently added the POST feature.
5164 [Ralf S. Engelschall]
5166 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
5167 modules as API functions and we forgot them at the big symbol renaming.
5168 [Ralf S. Engelschall]
5170 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

5173 *) Dynamically size the filename column of mod_autoindex output.
5176 *) Add the ability to do POST requests to the ab benchmarking tool.
5177 [Kurt Sussman <kls@best.com>] PR#2871
5179 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5180 5 to 10 because there are some users out there who always have 5 to 8
5181 variables in one RewriteRule and had to patch mod_rewrite.h for every
5182 release. So 15 should be now more than enough, even for them. (I never
5183 needed more than 4 in my RewriteRules ;-)
5184 [Ralf S. Engelschall]
5186 *) Make the proxy generate and understand Via: headers
5189 *) Change the proxy to use tables instead of array_headers for
5190 the header lines. [Martin Kraemer]
5192 *) Make sure the config.status file is not overridden when just
5193 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
5195 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
5196 provide a way to trace API changes that add functionality but do
5197 not create a compatibility issue for precompiled modules, etc.
5198 See include/ap_mmn.h for more details. [Randy Terbush]
5200 *) Fix suexec installation under `make install root=xxx' situation.
5201 [Ralf S. Engelschall]
5203 *) Extend the output of the -V switch to include the paths of all
5204 compiled-in configuration files, if they were overridden at
5205 compile time, for least astonishment of the user.
5208 *) When READing a request in ExtendedStatus mode, the "old"
5209 vhost, request and client information is not displayed.
5212 *) STATUS is no longer available. Full status information now
5213 run-time configurable using the ExtendedStatus directive.
5216 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5217 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5218 a function which can be used to perform bulk update operations
5219 on tables in a more efficient manner. [Dean Gaudet]
5221 *) SECURITY: Added compile-time and configurable limits for
5222 various aspects of reading a client request to avoid some simple
5223 denial of service attacks, including limits on maximum request-line
5224 size (LimitRequestLine), number of header fields (LimitRequestFields),
5225 and size of any one header field (LimitRequestFieldsize). Also added
5226 a configurable directive LimitRequestBody for limiting the size of the
5227 request message body. [Roy Fielding]
5229 *) Make status module aware of DNS and logging states, even if
5230 STATUS not defined. [Jim Jagielski]
5232 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
5234 *) Enhance mod_speling so that CheckSpelling can be used in
5235 <Directory> containers and .htaccess files. [Ken Coar]
5237 *) API: new ap_custom_response() function for hooking into the
5238 ErrorDocument mechanism at runtime [Doug MacEachern]
5240 *) API: new ap_uuencode() function [Doug MacEachern]
5242 *) API: scan_script_header_err_core() now "public" and renamed
5243 ap_scan_script_header_err_core() [Doug MacEachern]
5245 *) The 'status' module will now show the process pid's and their
5246 state even without full STATUS accounting. [Jim Jagielski]
5248 *) Restore the client IP address to the error log messages, this
5249 was lost during the transition from 1.2 to 1.3. Add a new
5250 function ap_log_rerror() which takes a request_rec * and
5251 formats it appropriately. [Dean Gaudet] PR#2661
5253 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5254 whitespace in input lines -- including within quoted strings.
5256 but leading and trailing whitespace should continue to be
5257 stripped [Martin Kraemer]
5259 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5260 the ugly use of an env. variable and use command-line args for
5261 alternate $PATH. Make more like advanced 'type's as well.
5264 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
5265 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
5266 <alain.st-denis@ec.gc.ca>] PR#2736
5268 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
5270 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
5271 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
5272 directory was renamed to src/os/os2/ for consistency.
5273 [Brian Havard, Ralf S. Engelschall]
5275 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5276 files (here modules) against other DSO files (here shared libraries).
5277 This is done by determining a subset of LIBS which can be safely used for
5278 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5279 disabled for all platforms to avoid problems with this (experimental)
5280 rule. But we provide it now for those people how ran into problems and
5281 want to came out by forcing linking against DSOs.
5282 [Ralf S. Engelschall] PR#2587
5284 *) Fix suEXEC start message: Has to be of `notice' level to really get
5285 printed together with the standard startup message because the `notice'
5286 level is handled special inside ap_log_error() for startup messages.
5287 [Ralf S. Engelschall] PR#2761 PR#2761 PR#2765

5293 [Youichirou Koga <y-koga@jp.FreeBSD.org>, Ralf S. Engelschall] PR#2756
5295 *) Allow ap_read_request errors to propagate through the normal request
5296 handling loop so that the connection can be properly closed with
5297 lingering_close, thus avoiding a potential TCP reset that would
5298 cause the client to miss the HTTP error response. [Roy Fielding]
5300 *) One more portability fix for APACI shadow tree support: Swap order of awk
5301 and sed in top-level configure script to avoid sed fails on some
5302 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
5303 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

5311 structure instead of just NULL. This fixes at least the RewriteMap
5312 programs under Win32. [Marco De Michele <mdemichele@tin.it>] PR#2483

5327 for users which extracted the distribution under 'umask 077'), so replace
5328 it by an explicit cp+chmod approach.

5360 the read_request error conditions of URI-too-long (414) and
5361 malformed header fields (400). [Roy Fielding] PR#2646
5363 *) Add support for the Max-Forwards: header line required by RFC2068 for
5364 the TRACE method. This allows apache to TRACE along a chain of proxies
5365 up to a predetermined depth. [Martin Kraemer]
5367 *) Fix SHARED_CORE rule: The CFLAGS_SHLIB variable is no longer doubled
5368 (compilers complained) and the .so.V.R.P filename extension was adjusted
5369 to correctly reflect the 1.3.2 version.

5407 *) Global renaming of C header files to both get rid of conflicts with third
5408 party packages and to again reach consistency:
5409 1. conf.h -> ap_config.h
5410 2. conf_auto.h -> ap_config_auto.h \ these are now merged
5411 3. ap_config.h -> ap_config_auto.h / in the config process
5412 4. compat.h -> ap_compat.h
5413 5. apctype.h -> ap_ctype.h
5414 Backward compatibility files for conf.h and compat.h were created.
5416 *) mod_mmap_static will no longer take action on requests unless at
5417 least one "mmapfile" directive is present in the configuration.
5418 This experimental module has to do some black magic to operate
5419 inside the current API and thus creates side-effects for other

5466 ap_isdigit(), ap_isupper(), ... which cast to an (unsigned char).
5467 This should work on most modern unixes.

5477 *) The APACI libexecdir was not extended with an "apache/" subdir
5478 if the installation prefix didn't already contain "apache", but
5479 it should be because the DSO files are Apache-specific. Now
5480 libexecdir is treated the same way sysconfdir, datadir, localstatedir
5481 and includedir are already treated.

5507 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems

5534 directory, bail out of the request with an error message. [W G Stoddard]
5536 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
5537 these are treated by Win32 as if they are ".." but are not detected by
5538 other machinery within Apache. This is something of a kludge but
5539 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5541 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5542 pools and thus pollutes libap (until the pool stuff is moved there).

5556 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5557 remove some of the classical hurdles for new users when setting up
5558 Apache. This is done per default because it is useful for the average
5559 user. Package authors can use the --without-confadjust option to disable
5560 these configuration adjustments.
5561 [Ralf S. Engelschall]
5563 *) Added an EXTRA_DEPS configuration parameter which can be used
5564 to add an extra Makefile dependency for the httpd target, for instance
5565 to external third-party libraries, etc.
5566 [Ralf S. Engelschall]
5568 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5569 as <IfModule>..</IfModule> sections) which can be used to skip or process
5570 contained commands dependend of ``-D PARAMETER'' options on the command
5571 line. This can be used to achieve logical conditions like <IfDefine
5572 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5573 and thus especially can be used for conditionally loading DSO-based
5574 modules via LoadModule, etc. [Ralf S. Engelschall]

5581 truncated which forced following HTTP headers to be data in the HTTP
5582 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5585 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5586 in top-level configure script to avoid sed fails on some platforms (for
5587 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5588 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5590 *) Improve performance of directory listings (mod_autoindex) by comparing
5591 integer keys (last-modified and size) as integers rather than converting
5592 them to strings first. Also use a set of explicit byte tests rather
5593 than strcmp() to check for parent directory-ness of an entry. Oh, and
5594 make sure the parent directory (if displayed) is *always* listed first
5595 regardless of the sort key. Overall performance winnage should be good
5596 in CPU time, instruction cache, and memory usage, particularly for large
5597 directories. [Ken Coar]
5599 *) Add a tiny but useful goody to APACI's configure script: The generation
5600 of a config.status script (as GNU Autoconf does) which remembers the used
5601 configure command and hence can be used to restore the configuration by
5602 just re-running this script or for remembering the configuration between
5604 [Ralf S. Engelschall]
5606 *) Add httpd -t (test) option for running configuration syntax tests only.
5607 If something is broken it complains and exits with a return code
5608 non-equal to 0. This can be used manually by the user to check the Apache
5609 configuration after editing and is also automatically used by apachectl
5610 on (graceful) restart command to make sure Apache doesn't die on restarts
5611 because of a configuration which is now broken since the last (re)start.
5612 This way `apachectl restart' can be used inside cronjobs without having
5613 to expect Apache to be falling down. Additionally the httpd -t can be run
5614 via `apachectl configtest'.

5754 spawn_child was obsoleted and moved to compat.h

5758 programs: ap_spawn_child_err() is used and the Win32 case now uses
5759 CreateProcess() instead of a low-level execl() (which caused problems in
5760 the past under Win32).

5763 *) A few cosmetics and trivial enhancements to APXS to make the
5764 generated Makefile more user friendly. [Ralf S. Engelschall]
5766 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5767 was updated to use the normal apache error processing, thereby allowing
5768 proxy errors to be treated by ErrorDocument's as well. For this
5769 purpose, a new module-to-core communication variable "error-notes"
5770 was introduced; the proxy (and possibly other modules) communicates
5771 its error text using this variable. Its content is copied to a new
5772 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5773 The old proxy special error routine ap_proxy_log_uerror()
5774 was replaced by regular ap_log_error() calls, many messages were made

5778 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5781 *) Transform the configure message "You need root privileges for suEXEC"
5782 from a fatal error into a (more friendly) warning because the building
5783 ("make") of Apache we can allow, of course. Root privileges are needed
5784 only for the installation step ("make install"). So make sure the

5847 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5849 *) The proxy cache would store an incorrect content-length in the cached

5851 of the original copy instead of using the cached copy.
5852 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5854 *) The Makefiles assumed that DSO files are build via $(LD). This
5855 is broken for two reasons: First we never defined at least LD=ld
5856 somewhere to make sure this works (it was silently assumed that most Make
5857 provide a built-in LD definition - ARGL!) and second using the generic LD
5858 variable is not the truth. Instead a special variable named LD_SHLIB is
5859 reasonable because although "ld" is usually the default, the command for
5860 building DSO files can be "libtool" or even "cc" on some systems.
5861 [Ralf S. Engelschall]
5863 *) Replace the AddVersionPlatform directive with ServerTokens which
5864 provides for more control over the format of the Server:
5865 header line. SERVER_SUBVERSION is no longer supported;

5873 not retrieved in src/Configure and thus was not useable.
5874 [Ralf S. Engelschall]
5876 *) Various Makefile consistency cleanups:
5877 - make OSDIR also automatically be relative to src/ like INCDIR
5878 - SUBDIRS is now generated in src/Makefile only and not in
5879 Makefile.config because it is a local define for this location.
5880 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5881 any Makefile but make sure that at least the "-K inline" is kept in
5883 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5884 - updated the dependencies theirself
5885 - removed not existing SHLIB variable from "clean" targets
5886 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5887 already exists and OBJS_PIC are also just plain objects and have not
5888 directly to do with "shared" things. The only difference is that they
5889 contain PIC. So OBJS_PIC is the more canonical name.
5890 - Updated the Makefile-dependency lines for OBJS_PIC
5891 - Removed the Makefile-dependency line in Configure to avoid double
5893 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5894 of xxx.lo as GNU libtool does with its PIC objects
5895 - reduce local complexity in modules Makefile.tmpl by moving the last
5896 existing target "depend" to the generation section in Configure, too.
5897 - removed the historical $(SPACER) which was used in the past together
5898 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5899 is no longer needed.
5900 - force the build and run of the gen_xxx programs under main/ as the
5901 first step before building the objects because it looks cleaner
5902 [Ralf S. Engelschall]
5904 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5907 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.

5911 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5913 *) When opening "configuration" files (like httpd.conf, htaccess
5914 and htpasswd), Apache will not allow them to be non-/dev/null
5915 device files. This closes a DoS hole. At the same time,
5916 we use ap_pfopen to open these files to handle timeouts.
5917 [Jim Jagielski, Martin Kraemer]
5919 *) Apache will now log the reason its httpd children exit if they exit
5920 due to an unexpected signal. (It requires a new porting define,
5921 SYS_SIGLIST, which if defined should point to a list of text
5922 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5924 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5925 like WIN32. Before, Win32 CGI's could have had sporadic failures
5926 if a chdir call from one thread was made between another chdir call
5927 and a spawn in another thread. So, for now don't chdir for CGI scripts
5928 in WIN32. The current CGI "spec" is unclear as to whether it's
5929 necessary. Long-term fix is to either serialize the chdir/spawn combo
5930 or use WIN32 native calls to spawn a process. This temp fix was
5931 necessary to remove this as a showstopper for 1.3's release.
5934 *) Cleanup the suEXEC support in APACI and make it more safe:
5935 1. Add big fat hint in INSTALL about risks and to read the
5936 htdocs/manual/suexec.html document before using the suexec-related
5938 2. Make sure the user has at least provided one --suexec-xxxx option
5939 (specifies suEXEC parameters) in addition to --enable-suexec option.
5940 If only --enable-suexec is given APACI stops with a hint to INSTALL
5941 and htdocs/manual/suexec.html documents.
5942 3. Provide two additional --suexec-xxxx options to make the suEXEC
5943 configuration complete (especially for package maintainers who else
5944 had to patch the source tree) by providing ways to configure minimal
5945 UID/GID and safe PATH, too.
5946 [Ralf S. Engelschall]
5948 *) Cleanup of the `configure --shadow' process:
5949 - make sure the configure script creates its temporary files in the
5950 shadow tree to avoid conflicts with parallel configure runs
5951 - removed unnecessary option "-r" from "rm" call for Makefiles
5952 - make sure the configure scripts creates the shadow-wrapper Makefile
5953 only when no shadow trees already exists
5954 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5955 when no more shadow trees exists
5956 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5957 as fast (in the past it needed 70sec, now it runs just 38sec)
5958 - make sure CVS does not complain about the created files
5959 Makefille.<gnutriple> and directories src.<gnutriple>
5960 [Ralf S. Engelschall]
5962 *) Added the ap_add_version_component() API routine and the
5963 AddVersionPlatform core directive. The first allows modules to
5964 declare themselves in the Server response header field value,
5965 augmenting the SERVER_SUBVERSION define in the Configuration file
5966 with run-time settings (more useful in a loadable-module environment).
5967 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5968 into the server version string. [Ken Coar] PR#2056
5970 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5973 *) Emit the "Accept-Range" header for the default handler.
5974 [Brian Behlendorf] PR#1464
5976 *) Add a note to httpd.conf-dist that apache will on some systems fail
5977 to start when the Group # is set to a negative or large positive value.
5980 *) Make sure the module execution order is correct even when some modules
5981 are loaded under runtime (`LoadModule') via the DSO mechanism:
5982 1. The list of loaded modules is now a dynamically allocated one
5983 and not the original statically list from modules.c
5984 2. The loaded modules are now correctly setup by LoadModule for
5985 later use by the AddModule command.
5986 3. When the DSO mechanism for modules is used APACI's `install'
5987 target now enables all created `LoadModule' lines per default because
5988 this is both already expected by the user _and_ needed to avoid
5989 confusion with the next point and reduces the Makefile.tmpl complexity
5990 4. When the DSO mechanism for modules is used, APACI's `install'
5991 target now additionally makes sure the module list is reconstructed
5992 via a complete `ClearModuleList+AddModule...' entry.
5993 5. The support tool `apxs' now also makes sure an AddModule command
5994 is added in addition to the LoadModule command.
5995 6. The modules.c generation was extended to now contain two
5996 comments to make sure no one is confused by the confusing terminology
5997 of loading/linking (we use load=link+load & link=activate instead of
5998 the obvious load=activate & link=link :-( )
5999 This way now there is no longer a difference under execution time between
6000 statically and dynamically linked modules.

6003 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
6004 Big Symbol Renaming. [Ralf S. Engelschall]
6006 *) Add a comment to mod_example.c showing the format of a FLAG command
6009 *) Standardized the time format in mod_status to match that of other
6010 places in the code (e.g. DATE_GMT). PR#1551
6012 *) Fix handling of %Z in timefmt strings for those platforms with no time
6013 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
6016 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
6017 feature compatible with 'UseCanonicalName off' by changing
6018 r->server->server_hostname to ap_get_server_name(). And I changed some
6019 functions which use r->server->port to use ap_get_server_port() instead,
6020 because if there's no Port directive in the config r->server->port is 0.
6023 *) get/set_module_config are trivial enough to be better off inline. Worth
6024 1.5% performance boost. [Dean Gaudet]
6026 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
6027 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
6030 *) [BS2000 security] BS2000 needs an extra authentication to initialize
6031 the task environment to the unprivileged User id. Otherwise CGI scripts
6032 would have a way to gain super user access. [Martin Kraemer]
6034 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
6035 absolute path, only log base name of logging source as is done
6036 in unix. [Martin Kraemer]
6038 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6039 the encoding type from the Accept-Encoding header (if it's there)
6040 and use it in the response, as that's probably what it'll be expecting.
6041 [Ronald.Tschalaer@psi.ch]
6043 *) Fix to mod_alias: translate_alias_redir is dealing with
6044 a URI, not a filename, so the check for drive letters for win32
6045 and emx is not necessary. [Dean Gaudet]
6047 *) WIN32: Allow .cmd as an executable extension.

6053 *) Child processes can now "signal" (by exiting with a status
6054 of APEXIT_CHILDFATAL) the parent process to abort and
6055 shutdown the server if the error in the child process was
6056 fatal enough. [Jim Jagielski]

6065 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
6067 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
6070 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6071 Additionally the checks for finding the vendor DSO library were moved
6072 from mod_so.c to Configure because first it needs $PLAT etc. and second
6073 mod_so already uses an abstraction layer and does not fiddle with the
6074 vendor functions itself.
6075 [Jens-Uwe Mager, Ralf S. Engelschall]
6077 *) PORT: Some optimization defines for NetBSD
6078 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6080 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6081 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6083 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6084 AIX variants should work fine, too. Even AIX 3.x should work). This is
6085 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6086 which we put into a os/unix/os-dso-aix.c file.
6087 [Ralf S. Engelschall]
6089 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6090 that we should use NET_SIZE_T == int but the include files force size_t.
6091 [Ralf S. Engelschall]
6093 *) Fix two bugs in select() handling in http_main.c.
6096 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6097 is unset (as it is in situations like timeouts) where it is unclear
6098 whether errno is set or not. [Martin Kraemer]
6100 *) Just having APACI's localstatedir is too general and not enough for most
6101 of the systems. 1.3b6 again required manual APACI patches by package
6102 maintainers from RedHat and FreeBSD because for their filesystem layout a
6103 little bit more flexibility in configuring the paths is needed. Hence we
6104 provide three additional configure options (--runtimedir, --logfiledir,
6105 --proxycachedir) which now can be used for more granular adjustments if
6106 --localstatedir is not enough to fit the particular needs. As a nice
6107 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6108 [Ralf S. Engelschall]
6110 *) Make the install root for "make install" in APACI's Makefile overrideable
6111 by package authors. This way we are even more friendly to package
6112 maintainers (especially Debian and RedHat) who build for the real prefix
6113 via "configure --prefix=/<real>" but use a different local prefix via
6114 "make root=/tmp/apache install" for rolling the package without bristling
6115 the target location on their system.
6116 [Ralf S. Engelschall]
6118 *) Workaround sed limitations in APACI's configure script by now
6119 substituting in chunks of 50 commands (because for instance HPUX's vendor
6120 sed has a limit of max. 98 commands)
6121 [Ralf S. Engelschall] PR#2136
6123 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
6124 [Ralf S. Engelschall] PR#2140
6126 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6127 RENAMING process because they are defined as pre-processor macros instead
6128 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6129 [Ralf S. Engelschall]
6131 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6132 substr() functions cannot be nested under vendor AWK from Solaris 2.6.

6135 *) Various bugfixes and cleanups for the APACI configure script:
6136 o fix IFS handling for _nested_ situation
6137 o fix Perl interpreter search: take first one found instead of last one
6138 o fix DSO consistency check
6139 o print error messages to stderr instead of stdout
6140 o add install-quiet for --shadow situation to Makefile stub
6141 o reduce complexity by avoiding sed-hacks for rule and module list loops

6144 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6146 *) Make sure the input field separator (IFS) shell variable is explicitly
6147 initialized correctly before _every_ `for' loop and also restored after
6148 the loops. [Ralf S. Engelschall]
6150 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6151 `magic' files from an existing Apache installation. Because people often
6152 customize these for own MIME and content types.

6190 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6192 *) If you start apache with the -S command line option it will dump
6193 out the parsed vhost settings. This is useful for folks trying
6194 to figure out what is wrong with their vhost configuration.
6195 (Other dumps may be added in the future.) [Dean Gaudet]
6197 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6198 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6201 *) Because /usr/local/apache is the default prefix the ``configure
6202 --compat'' option no longer has to set prefix, again. This way the
6203 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6205 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6206 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6207 to avoid "discard const" warnings. [Ralf S. Engelschall]
6209 *) If a specific handler is set for a file yet the request still
6210 ends up being handled by the default handler, log an error
6211 message before handling it. This catches things such as trying
6212 to use SSIs without mod_include enabled. [Marc Slemko]
6214 *) Fix error logging for the startup case where ap_log_error() still uses
6215 stderr as the target. Now the default log level is honored here, too.
6216 [Ralf S. Engelschall]

6223 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6225 Changes with Apache 1.3b6
6227 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6229 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6230 interface via the similar but proprietary HP/UX shl_xxx-style system
6231 calls. [Ralf S. Engelschall]
6233 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6234 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6235 Make. [Ralf S. Engelschall]
6237 *) ++++ THE BIG SYMBOL RENAMING ++++
6238 To avoid symbol clashes with third-party code compiled into the server,
6239 we globally applied the prefix "ap_" to the following classes of
6241 - Apache provided general functions (e.g., ap_cpystrn)
6242 - Public API functions (e.g., palloc, bgets)
6243 - Private functions which we can't make static (because of
6244 cross-object usage) but should be (e.g., new_connection)
6245 For backward source compatibility a new header file named compat.h was
6246 created which provides defines for the old symbol names and can be used
6247 by third-party module authors.
6250 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6251 problem under SVR4 is that there is no command flag to force the linker
6252 to export the global symbols of the httpd executable therewith they are
6253 available to the DSO's. Instead of problematic hacks like creating a
6254 dummy.so file (containing dummy references to all global symbols) the
6255 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6256 Placing the Apache core code itself into a DSO library named libhttpd.so.
6257 This way the global symbols _HAVE_ to be exported and thus are available
6258 to any manually loaded DSO's under runtime. To reduce the impact to the
6259 user to null we go even further and create a stub httpd executable which
6260 automatically keeps track of the DSO library loading itself and thus
6261 hides the complete mechanism from the user. Although the generation of
6262 this DSO library is automatically triggered for platforms which
6263 essentially need it (mostly all SVR4-derivates) it can be also enabled
6264 manually via the Rule SHARED_CORE. This can be interesting in the future
6265 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6266 features like graceful upgrades, or whatever.
6267 [Ralf S. Engelschall, Martin Kraemer]
6269 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6271 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6272 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6273 conventions while "clean" removes only stuff created by "all" targets,
6274 "distclean" additionally removes the stuff from the configuration
6275 process. This way "make distclean" (hence the name) provides a fresh
6276 source tree as it was for distribution.
6277 [Ralf S. Engelschall]
6279 *) Allow top-level (APACI) Makefile to break on build errors
6280 the same way the src/ subtree Makefiles breaks on them by replacing the
6281 initial APACI sed-subdir-display-kludge with a more clean
6282 variable-passing-solution: variable SDP can optionally hold the subdir
6283 prefix which is consistently used for displaying the subdir movement.
6284 This way even the top-level Makefile can stop correctly on errors as the
6285 user expects. [Ralf S. Engelschall]
6287 *) Fixed ordering of argument checks for RewriteBase directive.
6288 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6290 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6291 indicating that a module is being compiled for dynamic loading. Also
6292 remove #define IS_MODULE from modules and add SHARED_MODULE define
6293 to the mak/dsp files. [Alexei Kosut]
6295 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6296 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6298 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6300 *) Add documentation file and src/Configuration.tmpl entry for the
6301 experimental mod_mmap_static module. Because although it is and marked as
6302 an experimental one it is distributed and thus should be documented and
6303 prepared for configuration the same way as all others modules.
6304 [Ralf S. Engelschall]
6306 *) Add query (-q) option to apxs support tool to be able to manually query
6307 specific settings from apxs. This is needed for instance when you
6308 manually want to access Apache's header files and you need to assemble
6309 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6310 [Ralf S. Engelschall]
6312 *) Now src/Configure uses a fallback strategy for the shared object support
6313 on platforms where no explicit information is available: If a Perl
6314 installation exists we ask it about its shared object support and if it's
6315 the dlopen-style one we shamelessly guess the compiler and linker flags
6316 for creating shared objects from Perls knowledge. Of course, the user is
6317 warning about what we are doing and informed that he should send us
6318 the guessed flags when they work. [Ralf S. Engelschall]
6320 *) Provide APACI --without-support option to be able to disable the build
6321 and installation of the support tools from the src/support/ area.
6322 Although its useful to have these installed per default we should provide
6323 a way to compile and install without them for backward-compatibility.
6324 [Ralf S. Engelschall]
6326 *) Add of the new APache eXtenSion (apxs) support tool for building and
6327 installing modules into an _already installed_ Apache package through the
6328 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6329 this approach actually doesn't need the Apache source tree. The
6330 (APACI-installed) server package is enough, because this now includes the
6331 Apache C header files (PREFIX/include) and the new APXS tool
6332 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6333 module authors to build their Apache modules _OUTSIDE_ the Apache source
6334 tree while avoiding them to fiddle around with the totally platform
6335 dependend way of compiling DSO files. The tool supports all ranges of
6336 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6337 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6338 on-the-fly generate a minimalistic Makefile and sample module for the
6339 first step to provide both a quick success event and to demonstrate the
6340 APXS mechanism to module authors. [Ralf S. Engelschall]
6342 *) Fix core dumps in use of CONNECT in proxy.
6343 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6345 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6346 so that users have examples of how CustomLog can be used.
6349 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6350 the Apache distribution tree. Until Apache 1.3 there was no real
6351 out-of-the-box batch-capable build and installation procedure for the
6352 complete Apache package. This is now provided by a top-level "configure"
6353 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6354 to provide a GNU Autoconf-style frontend which is capable to both drive
6355 the old src/Configure stuff in batch and additionally installs the
6356 package with a GNU-conforming directory layout. Any options from the old
6357 configuration scheme are available plus a lot of new options for flexibly
6358 customizing Apache. [Ralf S. Engelschall]
6360 *) The floating point ap_snprintf code wasn't threadsafe.

6370 Configure knows which CC we are using. [Jim Jagielski]
6372 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6373 was defined in a parent directory. [Lars Eilebrecht]
6375 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6376 a generic printf-style routine that can call arbitrary output
6377 routines. Use this to replace http_bprintf.c. Add new routines
6378 psprintf(), pvsprintf() which allocate the exact amount of memory
6379 required for a string from a pool. Use psprintf() to clean up
6380 various bits of code which used ap_snprintf()/pstrdup().
6383 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6384 ap_snprintf() has different semantics and formatting codes than
6385 snprintf(). [Dean Gaudet]
6387 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6388 is necessary on at least Solaris where the /etc/rc?.d scripts
6389 are run with these signals ignored, and "SIG_IGN" settings are
6390 maintained across exec().

6418 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6419 therefore not exposed to %2F -> '/' translations and 2) the request
6420 is a proxy request, so we're not dealing with a local resource anyway.
6421 Without this, the proxy would fail to work for any URL's with
6422 %2f in them (occurs quite often in

6441 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6442 name was really too generic, added documentation for this directive to
6443 the mod_proxy.html and corrected the hyperlink to it in the
6444 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
6446 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6447 faster [Martin Kraemer]
6449 *) Make Configure die when you give it an unknown command switch.
6452 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6453 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6454 and per default compiled support programs have manual pages - just to
6455 document our stuff a little bit more and to be able to do really
6456 Unix-like installations ;-) [Ralf S. Engelschall]
6458 *) Major cleanups to the Configure script to make it and its generated
6459 Makefiles again readable and maintainable: add SRCDIR option, removed
6460 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6461 generated sections, consequently added Makefile headers with inheritance
6462 information, added subdir movement messages for easier following where
6463 the build process currently stays (more verbose then standard Make, less
6464 verbose than GNU make), same style to comments in the Configure script,
6465 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6467 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6468 from the ZeusBench benchmarking program and can be used to determine the
6469 response performance of an Apache installation. This version is
6470 officially licensed with Zeus Technology, Ltd. See the license agreement
6471 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
6472 [Ralf S. Engelschall]
6474 *) API: Various core functions that are definately not part of the API
6475 have been made static, and a few have been marked API_EXPORT. Still
6476 more have been marked CORE_EXPORT and are not intended for general
6477 use by modules. [Doug MacEachern, Dean Gaudet]
6479 *) mod_proxy was not clearing the Proxy-Connection header from
6480 requests; now it does. This did not violate any spec, however
6481 causes poor interactions when you are talking to remote proxies.
6482 [Marc Slemko] PR#1741

6485 [Ralf S. Engelschall]
6487 *) cfg_getline() was not properly handling lines that did not end
6488 with a line termination character. [Marc Slemko] PR#1869, 1909
6490 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6492 *) Clean up some undocumented behavior of mod_setenvif related to
6493 "merging" two SetEnvIf directives when they match the same header
6494 and regex. Document that mod_setenvif will perform comparisons in
6495 the order they appear in the config file. Optimize mod_setenvif by
6496 doing more work at config time rather than at runtime.
6499 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6500 to allow for modules to overrule them and to reduce redefinition
6501 warnings [Jim Jagielski]
6503 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6506 *) Making the hard-coded cross-module function call mime_find_ct() (from
6507 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6508 checking is really called even for proxy requests except for URLs with
6509 HTTP schemes (because there we can optimize by not running the type
6510 checking hooks due to the fact that the proxy gets the MIME Content-type
6511 from the remote host later). This change cleans up mod_mime by removing
6512 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6513 especially unbundles mod_proxy and mod_mime. This way they both now can
6514 be compiled as shared objects and are no longer tied together.
6515 [Ralf S. Engelschall]
6517 *) util.c cleanup and speedup. [Dean Gaudet]
6519 *) API: Clarification, pstrndup() will always copy n bytes of the source
6520 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6522 *) Mark module command_rec and handler_rec structures const so that they
6523 end up in the read-only data section (and are friendlier to systems
6524 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6526 *) Add check to the "Port" directive to make sure the specified
6527 port is in the appropriate range. [Ben Hyde]
6529 *) Performance improvements to invoke_handler().
6530 [Dmitry Khrustalev <dima@bog.msu.su>]
6532 *) Added support for building shared objects even for library-style modules
6533 (which are built from more than one object file). This now provides the
6534 ability to build mod_proxy as a shared object module. Additionally
6535 modules like mod_example are now also supported for shared object
6536 building because the generated Makefiles now no longer assume there is at
6537 least one statically linked module. [Ralf S. Engelschall]
6539 *) API: Clarify usage of content_type, handler, content_encoding,
6540 content_language and content_languages fields in request_rec. They
6541 must always be lowercased; and the strings pointed to shouldn't
6542 be modified (you must copy them to modify them). Fix a few bugs
6543 related to this. [Dean Gaudet]
6545 *) API: Clarification: except for RAW_ARGS, all command handlers can
6546 treat the char * parameters as permanent, and modifiable. There
6547 is no need to pstrdup() them. Clean up some needless pstrdup().
6550 *) Now mod_so keeps track of which module shared objects with which names
6551 are loaded and thus avoids multiple loading and unloading and irritating
6552 error_log messages. [Ralf S. Engelschall]
6554 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6555 environment variable in the apache core. But that tweaking interferes
6556 with mod_setenv. So don't tweak if the user has specified an explicit
6557 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6559 *) rputs() did not calculate r->sent_bodyct properly.
6560 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6562 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6563 name, or left unset if this value is unavailable. Apache was setting
6564 it to the IP address when unavailable.
6565 [Tony Finch <fanf@demon.net>] PR#1925
6567 *) Various improvements to the configuration and build support for compiling
6568 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6569 OSF1 support with GCC and vendor compilers was added. This way shared
6570 object support is now provided out-of-the-box for FreeBSD, Linux,
6571 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6572 [Ralf S. Engelschall]
6574 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6575 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6576 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6578 *) Fix one more special locking problem for RewriteMap programs in
6579 mod_rewrite: According to the documentation of flock(), "Locks are on
6580 files, not file descriptors. That is, file descriptors duplicated
6581 through dup(2) or fork(2) do not result in multiple instances of a lock,
6582 but rather multiple references to a single lock. If a process holding a
6583 lock on a file forks and the child explicitly unlocks the file, the
6584 parent will lose its lock.". To overcome this we have to make sure the
6585 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6586 the case by opening it in the child_init instead of the module_init API
6587 hook. [Ralf S. Engelschall] PR#1029
6589 *) Change to Location and LocationMatch semantics. LocationMatch no
6590 longer lets a single slash match multiple adjacent slashes in the
6591 URL. This change is for consistency with RewriteRule and
6592 AliasMatch. Multiple slashes have meaning in URLs that they do
6593 not have in (some) filesystems. Location on the other hand can
6594 be considered a shorthand for a more complicated regex, and it
6595 does match multiple slashes with a single slash -- which is
6596 also consistent with the Alias directive.
6597 [Dean Gaudet] related PR#1440
6599 *) Fix bug with mod_mime_magic causing certain files, including files
6600 of length 0, to result in no response from the server.
6603 *) The Configure script now generates src/include/ap_config.h which
6604 contains the set of defines used when Apache is compiled on a platform.
6605 This file can then be included by external modules before including
6606 any Apache header files in case they are being built separately from
6607 Apache. Along with this change, a couple of minor changes were
6608 made to make Apache's #defines coexist peacefully with any autoconf
6609 defines an external module might have. [Rasmus Lerdorf]
6611 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6612 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6613 chance by the API to initialize its per-server configuration and thus
6614 receives the wrong one from the main server. This is now avoided by
6615 remembering the server together with the config structure while
6616 configuring and later assuming there is no config when we see a
6617 difference between the remembered server and the one calling us.
6618 [Ralf S. Engelschall] PR#1790
6620 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6621 is automatically disabled under configure time when the dbm_xxx functions
6622 are not available. Second, two heavy source code errors in the DBM
6623 support code were fixed. This makes DBM RewriteMap's usable again after
6624 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6626 *) Now all configuration files support Unix-style line-continuation via
6627 the trailing backslash ("\") character. This enables us to write down
6628 complex or just very long directives in a more readable way. The
6629 backslash character has to be really the last character before the
6630 newline and it has not been prefixed by another (escaping) backslash.
6631 [Ralf S. Engelschall]
6633 *) When using ProxyPass the ?querystring was not passed correctly.
6634 [Joel Truher <truher@wired.com>]
6636 *) To deal with modules being compiled and [dynamically] linked
6637 at a different time from the core, the SERVER_VERSION and
6638 SERVER_BUILT symbols have been abstracted through the new
6639 API routines apapi_get_server_version() and apapi_get_server_built().
6642 *) WIN32: Preserve trailing slash in canonical path (and hence
6643 in PATH_INFO). [Paul Sutton, Ben Laurie]
6645 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6646 depending on the rev of Solaris and what mixture of modules
6647 are in use. So it has been disabled, and Solaris is back to
6648 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6649 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6650 up static content only servers. Or it may fail unpredictably.
6651 [Dean Gaudet] PR#1779, 1854, 1904
6653 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6656 *) API: Rewrite of absoluteURI handling, and in particular how
6657 absoluteURIs match vhosts. Unless a request is a proxy request, a
6658 "http://host" url is treated as if a similar "Host:" header had been
6659 supplied. This change was made to support future HTTP/1.x protocols
6660 which may require clients to send absoluteURIs for all requests.
6662 In order to achieve this change subtle changes were made to the API. In a
6663 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6664 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6665 by the core, modules must set it during the post_read_request or
6666 translate_names phase.
6668 Plus changes to the virtualhost test suite for absoluteURI testing.
6670 This fixes several bugs with the proxy proxying requests to vhosts
6671 managed by the same httpd.
6674 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6675 code from mod_rewrite. The vhost matching is now performed by a
6676 globally available function matches_request_vhost(). [Dean Gaudet]
6678 *) Reduce memory usage, and speed up ServerAlias support. As a

6689 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
6690 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
6692 *) API: A new source module main/util_uri.c; It contains a routine
6693 parse_uri_components() and friends which breaks a URI into its component
6694 parts. These parts are stored in a uri_components structure called
6695 parsed_uri within each request_rec, and are available to all modules.
6696 Additionally, an unparse routine is supplied which re-assembles the URI
6697 components back to an URI, optionally hiding the username:password@ part
6698 from ftp proxy requests, and other useful routines. Within the structure,
6699 you find on a ready-for-use basis:
6700 scheme; /* scheme ("http"/"ftp"/...) */
6701 hostinfo; /* combined [user[:password]@]host[:port] */
6702 user; /* user name, as in http://user:passwd@host:port/ */
6703 password; /* password, as in http://user:passwd@host:port/ */
6704 hostname; /* hostname from URI (or from Host: header) */
6705 port_str; /* port string (integer representation is in "port") */
6706 path; /* the request path (or "/" if only scheme://host was given) */
6707 query; /* Everything after a '?' in the path, if present */
6708 fragment; /* Trailing "#fragment" string, if present */
6709 This is meant to serve as the platform for *BIG* savings in
6710 code complexity for the proxy module (and maybe the vhost logic).
6713 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6714 ${map:key}) available for all location where a string is created in
6715 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6716 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6717 possible expansions are consequently usable at all string creation
6718 locations. [Ralf S. Engelschall]
6720 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6721 and not 1) and the per-virtual-server merging of directives. Now all
6722 directives except `RewriteEngine' and `RewriteOption' are either
6723 completely overridden (default) or completely inherited (when
6724 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6727 defined but disabled (`RewriteEngine off') in per-server context.

6730 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause

6733 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6734 (like SunOS and FreeBSD) which don't accept the locking of pipes
6735 directly. A new directive RewriteLock is introduced which can be used to
6736 setup a separate locking file which then is used for synchronization.

6751 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6752 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6754 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6755 type but with a special post-processing for the looked-up value: It
6756 parses it into alternatives according to `|' chars and then only one
6757 particular alternative is chosen randomly (this is an essential
6758 functionality needed for balancing between backend-servers when using
6759 Apache as a Reverse Proxy. The looked up value here is a list of
6760 servers). Second, `int' with the built-in maps named `tolower' and
6761 `toupper' which can be used to map URL parts to a fixed case (this is an
6762 essential feature to fix the case of server names when doing mass
6763 virtual-hosting with the help of mod_rewrite instead of using
6764 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6765 Jay Soffian <jay@cimedia.com>] PR#1631
6767 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6768 This directive lets Apache adjust the URL in Location-headers on HTTP
6769 redirect responses sent by the remote server. This way the virtually
6770 mapped area is no longer left on redirects and thus by-passed which is
6771 especially essential when running Apache as a reverse proxy.

6934 MAKE_TABLE_PROFILE which can help discover make_table()
6935 calls that use too small an initial guess, see alloc.c.
6938 *) Options and AllowOverride weren't properly merging in the main
6939 server setting inside vhosts (only an issue when you have no
6940 <Directory> or other section containing an Options that affects
6941 a request). Options +foo or -foo in the main_server wouldn't
6942 affect the main_server's lookup defaults. [Dean Gaudet]
6944 *) Variable 'cwd' was being used pointlessly before being set.
6947 *) r->allowed handling cleaned up in the standard modules.
6950 *) Some case-sensitivity issues cleaned up to be consistent with
6951 RFC2068. [Dean Gaudet]
6953 *) SIGURG doesn't exist everywhere.
6954 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6956 *) mod_unique_id was erroneously generating a second unique id when
6957 an internal redirect occured. Such redirects occur, for example,
6958 when processing a DirectoryIndex match. [Dean Gaudet]
6960 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6961 of the key and value. But in many cases this is not required
6962 because the key/value is a constant, or the value has been built
6963 by pstrcat() or other similar means. New routines table_addn,
6964 table_mergen, and table_setn have been added to the API, these
6965 routines do not pstrdup() their arguments. The core code and
6966 standard modules were changed to take advantage of these routines.
6967 The resulting server is up to 20% faster in some situations.
6969 Note that it is easy to get code subtly wrong if you pass a key/value
6970 which is in a pool other than the pool of the table. The only
6971 safe thing to do is to pass key/values which are in the pool of
6972 the table, or in one of the ancestors of the pool of the table.
6973 i.e. if the table is part of a subrequest, a value from the main
6974 request's pool is OK since the subrequest pool is a sub_pool of the
6975 main request's pool (and therefore has a lifespan at most as long as
6976 the main pool). There is debugging code which can detect improper
6977 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6978 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6980 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6981 which don't exist on disk more gracefully; handles vhosts properly.
6982 Update documentation to reflect the code -- if there's no
6983 MimeMagicFile directive then the module is not enabled.
6986 *) PORT: Some older *nix dialects cannot automatically start scripts
6987 which begin with a #! interpreter line (the shell starts the scripts
6988 appropriately on these platforms). Apache now supports starting of
6989 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6990 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6993 *) API: "typedef array_header table" removed from alloc.h, folks should
6994 have been writing to use table as if it were an opaque type, but even
6995 some standard modules got this wrong. By changing the definition
6996 to "typedef struct table table" module authors will receive compile
6997 time warnings that they're doing the wrong thing. This change
6998 facilitates future changes with more sophisticated table
6999 structures. Specifically, module authors should be using table_elts()
7000 to get access to an array_header * for the table. [Dean Gaudet]
7002 *) API: Renamed new_connection() to avoid namespace collision with LDAP
7003 library routines. [Ken Coar, Rasmus Lerdorf]
7005 *) WIN32: mod_speling is now available on the Win32 platform.
7008 *) For clarity the following compile time definition was changed:
7010 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
7012 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
7013 and not be a general notice that the OS has mmap(). Now the
7014 HAVE_MMAP/SHMGET #defines strictly are informational that the
7015 OS has that method of shared memory; the type to use for
7016 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
7017 and USE_SHMGET_SCOREBOARD). This allows outside modules to
7018 determine if shared memory is available and allows Apache
7019 to determine the best method to use for the scoreboard.
7022 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
7023 as do various earlier versions. It should be safe on all versions.

7025 the slack code. A few other cleanups for Unixware.

7048 The choice of flock vs. fcntl was made based on timings which showed that
7049 even on non-NFS, non-exported filesystems fcntl() was an order of
7050 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7051 that single socket users will see no difference. [Dean Gaudet] PR#467

7111 *) For maximum portability, the environment passed to CGIs should
7112 only contain variables whose names match the regex

7114 underscores over any character outside the regex. This
7115 affects HTTP_* variables, in a way that should be backward
7116 compatible for all the standard headers; and affects variables

7216 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller

7464 something which is not a FILE* [Martin Kraemer]
7466 *) Make single-exe Windows install. [Ben Laurie and Eric Esselink]
7468 *) WIN32: Make CGI work under Win95. [Ben Laurie and Paul Sutton]
7470 *) WIN32: Make index.html and friends work under Win95. [Ben Laurie]
7472 *) PORT: Solaris 2.4 needs Spencer regex, the system regex is broken.

7489 __NetBSD__. Workaround by defining NETBSD.
7490 [Chris Craft <ccraft@cncc.cc.co.us>] PR#977
7492 *) PORT: UnixWare 2.x requires -lgen for syslog.

7499 ["Pavel Yakovlev (Paul McHacker)" <hac@tomcat.olly.ru>]
7501 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
7502 use USE_SHMGET_SCOREBOARD.
7505 *) Various improvements in detecting config file errors (missing closing
7506 directives for <Directory>, <Files> etc. blocks, prohibiting global
7507 server settings in <VirtualHost> blocks, flagging unhandled multiple
7508 arguments to <Directory>, <Files> etc.)
7511 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
7512 variable to provide this one to suexec'd CGIs, too.
7513 [M.D.Parker <mdpc@netcom.com>] PR#1284
7515 *) New support tool: src/support/split-logfile, a sample Perl script which
7516 splits up a combined access log into separate files based on the
7517 name of the virtual host (listed first in the log records by "%v").
7520 Changes with Apache 1.3b2 (there is no 1.3b1)
7522 *) TestCompile was not passing $LIBS [Dean Gaudet]
7524 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7527 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7528 rudimentary memory debugger which can be used on live servers with
7529 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7530 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7531 and free() for each object. This is far more expensive and should
7532 only be used for testing with tools such as Electric Fence and
7533 Purify. See main/alloc.c for more details. [Dean Gaudet]
7535 *) Configure uses a sh trap and didn't set its exitcode properly.
7536 [Dean Gaudet] PR#1159
7538 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7539 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7540 From a given ip:port, regardless what the Host: header is, you can
7541 only reach the vhosts defined on that ip:port. The precedence of
7542 vhosts was reversed to match other precedences in the config --
7543 the earlier vhosts override the later vhosts. All vhost matching was
7544 moved into http_vhost.[ch]. [Dean Gaudet]
7546 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7547 be used for whatever reason is appropriate (i.e. format() warnings
7548 for printf style functions). Both are enabled only with
7549 gcc >= 2.7.x (so that we have fewer support issues with older
7550 versions). [Dean Gaudet]
7552 *) Fix support for Proxy Authentication (we were testing the response
7553 status too early). [Marc Slemko]
7555 *) CoreDumpDirectory directive directs where the core file is
7556 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7557 received. [Marc Slemko, Dean Gaudet]
7559 *) PORT: Support for Atari MINT.
7560 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7562 *) When booting, apache will now detach itself from stdin, stdout,
7563 and stderr. stderr will not be detached until after the config
7564 files have been read so you will be able to see initial error
7565 messages. After that all errors are logged in the error_log.
7566 This makes it more convenient to start apache via rsh, ssh,
7567 or crontabs. [Dean Gaudet] PR#523
7569 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7570 Also removed the auto-generated link to www.apache.org that was the
7571 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7573 *) send_fb would not detect aborted connections in some situations.
7576 *) mod_include would use uninitialized data when parsing certain
7577 expressions involving && and ||. [Brian Slesinsky] PR#1139
7579 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7581 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7583 *) mod_autoindex improperly counted &escapes; as more than one
7584 character in the description. It also improperly truncated
7585 descriptions that were exactly the maximum length.
7588 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7589 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7592 *) mod_include now uses symbolic names to check for request success
7593 and return HTTP errors, and correctly handles all types of
7594 redirections (previously it only did temporary redirect correctly).
7595 [Ken Coar, Roy Fielding]
7597 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7598 r->filename. Since those two are meant to be in sync with each other
7599 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7601 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7602 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7604 *) Inetd mode (which is buggy) uses timeouts without having setup the
7605 jmpbuffer. [Dean Gaudet] PR#1064
7607 *) Work around problem under Linux where a child will start looping
7608 reporting a select error over and over.
7609 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7611 *) Fixed error in proxy_util.c when looping through multiple host IP
7612 addresses. [Lars Eilebrecht] PR#974
7614 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7615 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7616 bytes before writing, but it will never split a log entry across a
7617 buffer boundary. [Dean Gaudet]
7619 *) API: the short_score record has been split into two pieces, one which
7620 the parent writes on, and one which the child writes on. As part of
7621 this change the get_scoreboard_info() function was removed, and
7622 scoreboard_image was exported. This change fixes a race condition
7623 in file based scoreboard systems, and speeds up changes involving the
7624 scoreboard in earlier 1.3 development. [Dean Gaudet]
7626 *) API: New register_other_child() API (see http_main.h) which allows
7627 modules to register children with the parent for maintenance. It
7628 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7630 *) API: New piped_log API (see http_log.h) which implements piped logs,
7631 and will use register_other_child to implement reliable piped logs
7632 when it is available. The reliable piped logs part can be disabled
7633 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7634 logs is only available on Unix. [Dean Gaudet]
7636 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7637 meets_conditions(). This allows conditional HTTP selection to be
7638 handled separately from the storing of the header fields, and provides
7639 the ability for CGIs to set their own ETags for conditional checking.
7640 [Ken Coar, Roy Fielding] PR#895
7642 *) Changes to mod_log_config to allow naming of format strings.
7643 Format nicknames are defined with "LogFormat fmt nickname", and can
7644 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7647 *) New module, "mod_speling", which can help find files even when
7648 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7650 *) API: New function child_terminate() triggers the child process to
7651 exit, while allowing the child finish what it needs to for the
7652 current request first.
7653 [Doug MacEachern, Alexei Kosut]
7655 *) Windows now defaults to using full status reports with mod_status.
7656 [Alexei Kosut] PR #1094
7658 *) *Really* disable all mod_rewrite operations if the engine is off.
7659 Some things (like RewriteMaps) were checked/performed even if they
7660 weren't supposed to be. [Ken Coar] PR #991
7662 *) Implement a new timer scheme which eliminates the need to call alarm() all
7663 the time. Instead a counter in the scoreboard for each child is used to
7664 show when the child has made forward progress. The parent samples this
7665 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7666 progress has been made in the timeout period. This reduces the static
7667 request best-case syscall count to 22 from 29. This scheme is only
7668 used by systems with memory-based scoreboards. [Dean Gaudet]
7670 *) The proxy now properly handles CONNECT requests which are sent
7671 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7673 *) A script called apachectl has been added to the support
7674 directory. This script allows you to do things such as
7675 "apachectl start" and "apachectl restart" from the command
7678 *) Modules and core routines are now put into libraries, which
7679 simplifies the link line tremendously (among other advantages).
7682 *) Some of the MD5 names defined in Apache have been renamed to have
7683 an `ap_' prefix to avoid conflicts with routines supplied by
7684 external libraries. [Ken Coar]
7686 *) Removal of mod_auth_msql.c from the distribution. There are many
7687 other options for databases today. Rather than offer one option,
7688 offer none at this time. mod_auth_msql and other SQL database
7689 authentication modules can be found at the Apache Module Registry.
7690 http://modules.apache.org/ It would be nice to offer a generic
7691 mod_auth_sql option in the near future.
7693 *) PORT: BeOS support added [Alexei Kosut]
7695 *) Configure no longer accepts the -make option, since it creates
7696 Makefile on the fly based on Makefile.tmpl and Configuration.
7698 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7699 of forcibly killing off all its processes and exiting without
7700 cleaning up. [Alexei Kosut]
7702 *) API: A new field in the request_rec, r->mtime, has been added to
7703 avoid gratuitous parsing of date strings. It is intended to hold
7704 the last-modified date of the resource (if applicable). An
7705 update_mtime() routine has also been added to advance it if
7706 appropriate. [Roy Fielding, Ken Coar]
7708 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7709 deny access to the directory with a HTTP_FORBIDDEN. The previous
7710 behavior was to ignore the htaccess file if it could not be read.
7711 This change may make some setups with unreadable htaccess files
7712 stop working. [Marc Slemko] PR#817
7714 *) Add aplog_error() providing a mechanism to define levels of
7715 verbosity to the server error logging. This addition also provides
7716 the ability to log errors using syslogd. Error logging is configurable
7717 on a per-server basis using the LogLevel directive. Conversion
7718 of log_*() in progress. [Randy Terbush]
7720 *) Further enhance aplog_error() to not log filename, line number, and
7721 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7723 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7724 converted to long ones. Backslashes are converted to forward
7725 slashes. Case is converted to lower. Parts of URLs that do not
7726 correspond to files are left completely alone. [Ben Laurie]
7728 *) PORT: 2 new OSs added to the list of ports:
7729 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7730 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7732 *) Add the server version (SERVER_VERSION macro) to the "server
7733 configured and running" entry in the error_log. Also build an
7734 object file at link-time that contains the current time
7735 (SERVER_BUILT global const char[]), and include that in the
7738 *) Set r->headers_out when sending responses from the proxy.
7739 This fixes things such as the logging of headers sent from
7740 the proxy. [Marc Slemko] PR#659
7742 *) support/httpd_monitor is no longer distributed because the
7743 scoreboard should not be file based if at all possible. Use
7744 mod_status to see current server snapshot.
7746 *) (set_file_slot): New function, allowing auth directives to be
7747 independent of the server root, so the server documents can be
7748 moved to a different directory or machine more easily.
7749 [David J. MacKenzie]
7751 *) If no TransferLog is given explicitly, decline
7752 to log. This supports coexistence with other logging modules,
7753 such as the custom one that UUNET uses. [David J. MacKenzie]
7755 *) Check for titles in server-parsed HTML files.
7756 Ignore leading newlines and returns in titles. The old behavior
7757 of replacing a newline after <title> with a space causes the
7758 title to be misaligned in the listing. [David J. MacKenzie]
7760 *) Change mod_cern_meta to be configurable on a per-directory basis.
7761 [David J. MacKenzie]
7763 *) Add 'Include' directive to allow inclusion of configuration
7764 files within configuration files. [Randy Terbush]
7766 *) Proxy errors on connect() are logged to the error_log (nothing
7767 new); now they include the IP address and port that failed
7768 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7770 *) Various architectures now define USE_MMAP_FILES which causes
7771 the server to use mmap() for static files. There are two
7772 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7773 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7774 number of bytes written in one cycle from a single mmap()d object,
7775 default 32768). [Dean Gaudet]
7777 *) API: Added post_read_request API phase which is run right after reading
7778 the request from a client, or right after an internal redirect. It is
7779 useful for modules setting environment variables that depend only on
7780 the headers/contents of the request. It does not run during subrequests
7781 because subrequests inherit pretty much everything from the main
7782 request. [Dean Gaudet]
7784 *) Added mod_unique_id which is used to generate a unique identifier for
7785 each hit, available in the environment variable UNIQUE_ID.
7788 *) init_modules is now called after the error logs have been opened. This
7789 allows modules to emit information messages into the error logs.
7792 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7793 information for case where proxy module is not available. [Marc Slemko]
7795 *) PORT: Apache has need for mutexes to serialize its children around
7796 accept. In prior versions either fcntl file locking or flock file
7797 locking were used. The method is chosen by the definition of
7798 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7799 and FLOCK for flock(). New options have been added:
7800 - SYSVSEM to use System V style semaphores
7801 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7802 - USLOCK to use IRIX uslock
7803 Based on timing various techniques, the following changes were made
7805 - Linux 2.x uses flock instead of fcntl
7806 - Solaris 2.x uses pthreads
7807 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7808 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7809 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7810 Martijn Koster <m.koster@pobox.com>]
7812 *) PORT: The semantics of accept/select make it very desirable to use
7813 mutexes to serialize accept when multiple Listens are in use. But
7814 in the case where only a single socket is open it is sometimes
7815 redundant to serialize accept(). Not all unixes do a good job with
7816 potentially dozens of children blocked on accept() on the same
7817 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7818 the server will avoid serialization when listening on only one socket,
7819 and use serialization when listening on multiple sockets.
7820 [Dean Gaudet] PR#467
7822 *) Configure changes: TestLib replaced by TestCompile, which has
7823 some additional capability (such as doing a sanity check of
7824 the compiler and flags selected); the version of Solaris is now
7825 available via the #define value of SOLARIS2; IRIX n32bit libs
7826 now supported and selectable by new Configuration Rule: IRIXN32;
7827 We no longer default to -O2 optimization. [Jim Jagielski]
7829 *) Updated Configure: Configuration now uses AddModule to specify
7830 module source or binary file location, relative to src directory.
7831 Modules can be dropped into modules/extra, or in their own
7832 directory, and modules can come with a Makefile or Configure can
7833 create one. Modules can add compiler or library information to
7834 generated Makefiles. [Paul Sutton]
7836 *) Source core re-organisation: distributed modules are now in
7837 modules/standard. All other source code is in main. OS-specific
7838 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7840 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7843 *) Fix another long-standing bug in sub_req_lookup_file where it would
7844 happily skip past access checks on subdirectories looked up with
7845 relative paths. (It's used by mod_dir, mod_negotiation,
7846 and mod_include.) [Dean Gaudet]
7848 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7849 N is the number of <Directory> sections, and M is the number of
7850 components in the filename of an object.
7852 To achieve this optimization the following config changes were made:
7853 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7854 <Files>s, and <Location>s now treat a slash as a special
7855 character. For example "/home/*/public_html" previously would
7856 match "/home/a/andrew/public_html", now it only matches things
7857 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7858 - It's possible now to use [] wildcarding in <Directory>, <Files>
7860 - Regex <Directory>s are applied after all non-regex <Directory>s.
7864 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7865 and corrupted paths. [Dean Gaudet]
7867 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7868 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7869 be accessed now via backreferences $1..$9 in RewriteConds test-against
7870 strings in addition to RewriteRules subst string. Second the grouped
7871 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7872 via backreferences %1..%9 both in following RewriteCond test-against
7873 strings and RewriteRules subst string. This provides maximum flexibility
7874 through the use of backreferences.
7875 Additionally the rewriting engine was cleaned up by putting common
7876 code to the new expand_backrefs_inbuffer() function.
7877 [Ralf S. Engelschall]
7879 *) When merging the main server's <Directory> and <Location> sections into
7880 a vhost, put the main server's first and the vhost's second. Otherwise
7881 the vhost can't override the main server. [Dean Gaudet] PR#717
7883 *) The <Directory> code would merge and re-merge the same section after
7884 a match was found, possibly causing problems with some modules.
7887 *) ip-based vhosts are stored and queried using a hashing function, which
7888 has been shown to improve performance on servers with many ip-vhosts.
7889 Some other changes had to be made to accommodate this:
7890 - the * address for vhosts now behaves like _default_
7891 - the matching process now is:
7892 - match an ip-vhost directly via hash (possibly matches main
7894 - if that fails, just pretend it matched the main server
7895 - if so far only the main server has been matched, perform
7896 name-based lookups (ServerName, ServerAlias, ServerPath)
7897 *only on name-based vhosts*
7898 - if they fail, look for _default_ vhosts
7899 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7901 *) dbmmanage overhaul:
7902 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7903 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7904 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7905 - provide better seed for rand
7906 - prompt for password as per getpass(3) (turn off echo, read from
7908 - use "newstyle" crypt based on $Config{osname} ($^O)
7909 - will not add a user if already in database, use new `update' command
7911 - added `check' command to check a users' password
7912 - added `import' command to convert existing password text-files or
7913 dbm files exported with `view'
7914 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7917 *) Added psocket() which is a pool form of socket(), various places within
7918 the proxy weren't properly blocking alarms while registering the cleanup
7919 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7920 was a bug where the client socket was being close()d twice due a still
7921 registered cleanup. [Dean Gaudet]
7923 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7926 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7927 [Jason Venner <jason@idiom.com>] PR#667
7929 *) Enable ``=""'' for RewriteCond directives to match against
7930 the empty string. This is the preferred way instead of ``^$''.
7931 [Ralf S. Engelschall]
7933 *) Fixed an infinite loop in mod_imap for references above the server root
7934 [Dean Gaudet] PR#748
7936 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7937 SendBufferSize, so that the TCP window can be set appropriately
7938 for LFNs. [Phillip A. Prindeville]
7940 *) mod_browser has been replaced by the more general mod_setenvif
7941 (courtesy of Paul Sutton). BrowserMatch* directives are still
7942 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7943 UnSetEnvIfZero directives. [Ken Coar]
7945 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7946 order for remote_host to be set (for logging, or for the env var
7947 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7950 *) mod_access overhaul:
7951 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7952 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7953 - Critical path was sped up by pre-computing a few things at config time.
7954 - The undocumented syntax "allow user-agents" was removed,
7955 the replacement is "allow from env=foobar" combined with mod_browser.
7956 - When used with hostnames it now forces a double-reverse lookup
7957 no matter what the directory settings are. This double-reverse
7958 doesn't affect any of the other routines that use the remote
7959 hostname. In particular it's still passed to CGIs and the log
7960 without the double-reverse check. Related PR#860.
7963 *) When a large bwrite() occurs (larger than the internal buffer size),
7964 while there is already something in the buffer, apache will combine
7965 the large write and the buffer into a single writev(). (This is
7966 in anticipation of using mmap() for reading files.)
7969 *) In obscure cases where a partial socket write occurred while chunking,
7970 Apache would omit the chunk header/footer on the next block. Cleaned
7971 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7972 a bug where a long pause in DNS lookups could cause the last packet
7973 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7975 *) API: Added child_exit function to module structure. This is called
7976 once per "heavy-weight process" just before a server child exit()'s
7977 e.g. when max_requests_per_child is reached, etc.
7978 [Doug MacEachern, Dean Gaudet]
7980 *) mod_include cleanup showed that handle_else was being used to handle
7981 endif. It didn't cause problems, but it was cleaned up too.
7984 *) mod_cern_meta would attempt to find meta files for the directory itself
7985 in some cases, but not in others. It now avoids it in all cases.
7988 *) mod_mime_magic would core dump if there was a decompression error.
7989 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7991 *) PORT: some variants of DGUX require -lsocket -lnsl
7992 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7994 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7995 by the various fields (name, size, et cetera), either in ascending
7996 or descending order. Just click on the column header. [Ken Coar]
7998 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7999 CPUs like the Alpha. Apache still stores ints in pointers, but that's
8000 the relatively safe direction. [Dean Gaudet] PR#344
8002 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
8003 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
8005 *) child_main avoids an unneeded call to select() when there is only one
8006 listening socket. [Dean Gaudet]
8008 *) In the event that the server is starved for idle servers it will
8009 spawn 1, then 2, then 4, ..., then 32 servers each second,
8010 doubling each second. It'll also give a warning in the errorlog
8011 since the most common reason for this is a poor StartServers
8012 setting. The define MAX_SPAWN_RATE can be used to raise/lower
8013 the maximum. [Dean Gaudet]
8015 *) Apache now provides an effectively unbuffered connection for
8016 CGI scripts. This means that data will be sent to the client
8017 as soon as the CGI pauses or stops output; previously, Apache would
8018 buffer the output up to a fixed buffer size before sending, which
8019 could result in the user viewing an empty page until the CGI finished
8020 or output a complete buffer. It is no longer necessary to use an
8021 "nph-" CGI to get unbuffered output. Given that most CGIs are written
8022 in a language that by default does buffering (e.g. perl) this
8023 shouldn't have a detrimental effect on performance.
8025 "nph-" CGIs, which formerly provided a direct socket to the client
8026 without any server post-processing, were not fully compatible with
8027 HTTP/1.1 or SSL support. As such they would have had to implement
8028 the transport details, such as encryption or chunking, in order
8029 to work properly in certain situations. Now, the only difference
8030 between nph and non-nph scripts is "non-parsed headers".
8031 [Dean Gaudet, Sameer Parekh, Roy Fielding]
8033 *) If a BUFF is switched from buffered to unbuffered reading the first
8034 bread() will return whatever remained in the buffer prior to the
8035 switch. [Dean Gaudet]
8037 Changes with Apache 1.3a1
8039 *) Added another Configure helper script: TestLib. It determines
8040 if a specified library exists. [Jim Jagielski]
8042 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8043 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8046 *) PORT: Some architectures use size_t for various lengths in network
8047 functions such as accept(), and getsockname(). The definition
8048 NET_SIZE_T is used to control this. [Dean Gaudet]
8050 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8051 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8052 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8054 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8055 [Igor N Kovalenko <infoh@mail.wplus.net>]
8057 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8058 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8059 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8060 [Dean Gaudet] related PR#875
8062 *) API: Correct child_init() slot declaration from int to void, to
8063 match the init() declaration. Update mod_example to use the new
8066 *) added transport handle slot (t_handle) to the BUFF structure
8069 *) get_client_block() returns wrong length if policy is
8070 REQUEST_CHUNKED_DECHUNK.
8071 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
8073 *) Support the image map format of FrontPage. For example:

8077 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
8078 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
8080 *) AddModuleInfo directive for mod_info which allows you to annotate
8081 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8083 *) Added NoProxy directive to avoid using ProxyRemote for selected
8084 addresses. Added ProxyDomain directive to cause unqualified
8085 names to be qualified by redirection.
8086 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8088 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8089 header to the remote host in the proxy. [Sameer Parekh and
8092 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8093 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8094 URLs, fixed rewritelog(), fixed forced response code handling on
8095 redirects from within .htaccess files, disabled pipe locking under
8096 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8097 no substitution, bugfixed situations where HostnameLookups is off, made
8098 mod_rewrite more thread-safe for NT port and fixed problem when creating
8099 an empty query string via "xxx?".
8100 This update also removes the copyright of Ralf S. Engelschall,
8101 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8102 exclusively copyrighted by the Apache Group now. This happened because
8103 the author now has gifted mod_rewrite exclusively to the Apache Group and
8104 no longer maintains an external version.
8105 [Ralf S. Engelschall]
8107 *) API: Added child_init function to module structure. This is called
8108 once per "heavy-weight process" before any requests are handled.
8109 See http_config.h for more details. [Dean Gaudet]
8111 *) Anonymous_LogEmail was logging on each subrequest.
8112 [Dean Gaudet] PR#421, 868
8114 *) API: Added is_initial_req() which tests if the request being
8115 processed is the initial request, or a subrequest.
8118 *) Extended SSI (mod_include) now handles additional relops for
8119 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8121 *) Configure fixed to correctly propagate user-selected options and
8122 settings (such as CC and OPTIM) to Makefiles other than
8123 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8125 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8126 directory indices to start with the contents of the HeaderName file
8127 if there is one. If there isn't one, the behaviour is unchanged.
8128 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8130 *) WIN32: Modules can now be dynamically loaded DLLs using the
8131 LoadModule/LoadFile directives. Note that module DLLs must be
8132 compiled with the multithreaded DLL version of the runtime library.
8133 [Alexei Kosut and Ben Laurie]
8135 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8136 This allows the admin to completely remove automatic indexing
8137 from the server, while still supporting the basic functions of
8138 trailing-slash redirects and DirectoryIndex files. Note that if
8139 you're carrying over an old Configuration file and you use directory
8140 indexing then you'll want to add:
8142 Module autoindex_module mod_autoindex.o
8144 before mod_dir in your Configuration. [Dean Gaudet]
8146 *) popendir/pclosedir created to properly protect directory scanning.
8147 [Dean Gaudet] PR#525
8149 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8150 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8151 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8154 *) The AccessFileName directive can now take more than one filename.
8155 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8157 *) The new mod_mime_magic can be used to "magically" determine the type
8158 of a file if the extension is unknown. Based on the unix file(1)
8159 command. [Ian Kluft <ikluft@cisco.com>]
8161 *) We now determine and display the time spent processing a
8162 request if desired. [Jim Jagielski]
8164 *) mod_status: PID field of "dead" child slots no longer displays
8165 main httpd process's PID. [Jim Jagielski]
8167 *) Makefile.nt added - to build all the bits from the command line:
8168 nmake -f Makefile.nt
8169 Doesn't yet work properly. [Ben Laurie]
8171 *) Default text of 404 error is now "Not Found" rather than the
8172 potentially misleading "File Not Found". [Ken Coar]
8174 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8175 for the net if we require people that actually need this data to
8176 enable it. [Linus Torvalds]
8178 *) directory_walk() is an expensive function, keep a little more state to
8179 avoid needless string counting. Add two new functions make_dirstr_parent
8180 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8181 The new functions are a little less general than make_dirstr, but
8182 work more efficiently (less memory, less string counting).
8185 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8186 to LDFLAGS) to avoid complications with lex rules in make files.
8187 [Dean Gaudet] PR#372
8189 *) run_method optimized to avoid needless scanning over NULLs in the
8190 module list. [Dean Gaudet]
8192 *) Revamp of (unix) scoreboard management code such that it avoids
8193 unnecessary traversals of the scoreboard on each hit. This is
8194 particularly important for high volume sites with a large
8195 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8196 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8197 httpd.h. [Dean Gaudet]
8199 *) In configurations using multiple Listen statements it was possible for
8200 busy sockets to starve other sockets of service. [Dean Gaudet]
8202 *) Added hook so standalone_main can be replaced at compile time
8203 (define STANDALONE_MAIN)
8206 *) Lowest-level read/write functions in buff.c will be replaced with
8207 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8208 compile time. The default sfio discipline will behave as apache
8209 would without sfio compiled in.
8212 *) Enhance UserDir directive (mod_userdir) to accept a list of
8213 usernames for the 'disable' keyword, and add 'enable user...' to
8214 selectively *en*able userdirs if they're globally disabled.
8217 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8218 will work with Netscape dbm files. (dbmmanage will probably not
8219 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8221 *) Add a ListenBacklog directive to control the backlog parameter
8222 passed to listen(). Also change the default to 511 from 512.
8225 *) API: A new handler response DONE which informs apache that the
8226 request has been handled and it can finish off quickly, similar to
8227 how it handles errors. [Rob Hartill]
8229 *) Turn off chunked encoding after sending terminating chunk/footer
8230 so that we can't do it twice by accident. [Roy Fielding]
8232 *) mod_expire also issues Cache-Control: max-age headers.
8235 *) API: Added kill_only_once option for free_proc_chain so that it won't
8236 aggressively try to kill off specific children. For fastcgi.
8237 [Stanley Gambarin <gambarin@OpenMarket.com>]
8239 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8241 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8242 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8243 attributes in the FancyIndexing IMG tags. [Ken Coar]
8245 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8247 *) PORT: Added Windows NT support
8248 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8250 Changes with Apache 1.2.6
8252 *) mod_include when using XBitHack Full would send ETags in addition to
8253 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8254 [Dean Gaudet] PR#1133
8256 *) SECURITY: When a client connects to a particular port/addr, and
8257 gives a Host: header ensure that the virtual host requested can
8258 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8260 *) Support virtual hosts with wildcard port and/or multiple ports
8261 properly. [Ed Korthof <ed@organic.com>]
8263 *) Fixed some case-sensitivity issues according to RFC2068.
8266 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8267 and mod_include.c. [Dean Gaudet]
8269 *) Variable 'cwd' was being used pointlessly before being set.
8272 *) SIGURG doesn't exist on all platforms.
8273 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8275 *) When an error occurs during a POST, or other operation with a
8276 request body, the body has to be read from the net before allowing
8277 a keepalive session to continue. [Roy Fielding] PR#1399
8279 *) When an error occurs in fcntl() locking suggest the user look up
8280 the docs for LockFile. [Dean Gaudet]
8282 *) table_set() and table_unset() did not deal correctly with
8283 multiple occurrences of the same key. [Stephen Scheck
8284 <sscheck@infonex.net>, Ben Laurie] PR#1604
8286 *) send_fd_length() did not calculate total_bytes_sent properly in error
8287 cases. [Ben Reser <breser@regnow.com>] PR#1366
8289 *) r->connection->user was allocated in the wrong pool causing corruption
8290 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8292 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8293 Also removed the auto-generated link to www.apache.org that was the
8294 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8296 *) Multiple "close" tokens may have been set in the "Connection"
8297 header, not an error, but a waste.
8298 [Ronald.Tschalaer@psi.ch] PR#1683
8300 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8301 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8303 *) It appears the "257th byte" bug (see
8304 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8305 at the 256th byte as well. Fixed. [Dean Gaudet]
8307 *) mod_rewrite would not handle %3f properly in some situations.
8310 *) Apache could generate improperly chunked HTTP/1.1 responses when
8311 the bputc() or rputc() functions were used by modules (such as
8312 mod_include). [Dean Gaudet]
8314 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8315 some ports. [Ralf Engelschall]
8317 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8319 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8321 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8323 Changes with Apache 1.2.5
8325 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8326 only an issue on systems without a MAXDNAME define or where
8327 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8329 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8332 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8333 directory listings. [Marc Slemko]
8335 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8338 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8339 is used to read various types of files such as htaccess and
8340 htpasswd files. [Marc Slemko]
8342 *) SECURITY: Ensure that the buffer returned by ht_time is always
8343 properly null terminated. [Marc Slemko]
8345 *) SECURITY: General mod_include cleanup, including fixing several
8346 possible buffer overflows and a possible infinite loop. This cleanup
8347 was done against 1.3 code and then backported to 1.2, the result
8348 is a large difference (due to indentation cleanup in 1.3 code).
8349 Users interested in seeing a smaller set of relevant differences
8350 should consider comparing against src/modules/standard/mod_include.c
8351 from the 1.3b3 release. Non-indentation changes to mod_include
8352 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8354 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8355 including fixing a possible buffer overflow. This cleanup also
8356 was done with 1.3 code as a basis, see the the previous note
8357 about mod_include. [Dean Gaudet]
8359 *) SECURITY: If a htaccess file can not be read due to bad
8360 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8361 The previous behavior was to ignore the htaccess file if it could not
8362 be read. This change may make some setups with unreadable
8363 htaccess files stop working. PR#817 [Marc Slemko]
8365 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8366 Make it O(n). This inefficiency could be used to mount a denial
8367 of service attack against the Apache server. Thanks to
8368 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
8371 *) mod_include used uninitialized data for some uses of && and ||.

8374 *) mod_imap should decline all non-GET methods.
8375 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
8377 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8379 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8380 r->filename. Since those two are meant to be in sync with each other
8381 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
8383 *) mod_include did not properly handle all possible redirects from sub-
8384 requests. [Ken Coar]
8386 *) Inetd mode (which is buggy) uses timeouts without having setup the
8387 jmpbuffer. [Dean Gaudet] PR#1064
8389 *) Work around problem under Linux where a child will start looping
8390 reporting a select error over and over.
8391 [Rick Franchuk <rickf@transpect.net>] PR#1107
8393 Changes with Apache 1.2.4
8395 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8396 always making requests with the full-URI instead of just the URI path.
8397 [Marc Slemko, Roy Fielding]
8399 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8400 on this platform. [Marc Slemko]
8402 Changes with Apache 1.2.3
8404 *) The request to a remote proxy was mangled if it was generated as the
8405 result of a ProxyPass directive. URL schemes other than http:// were not
8406 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
8407 PR#812 [Lars Eilebrecht]
8409 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8410 information for case where proxy module is not available. [Marc Slemko]
8412 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8413 do for errors and cached responses. [Roy Fielding]
8415 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8417 Changes with Apache 1.2.2 [not released]
8419 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8420 happily skip past access checks on subdirectories looked up with relative
8421 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8424 *) Add lockfile name to error message printed out when
8425 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8428 *) Enhanced the chunking and error handling inside the buffer functions.
8429 [Dean Gaudet, Roy Fielding]
8431 *) When merging the main server's <Directory> and <Location> sections into
8432 a vhost, put the main server's first and the vhost's second. Otherwise
8433 the vhost can't override the main server. [Dean Gaudet] PR#717
8435 *) The <Directory> code would merge and re-merge the same section after
8436 a match was found, possibly causing problems with some modules.
8439 *) Fixed an infinite loop in mod_imap for references above the server root.
8440 [Dean Gaudet] PR#748
8442 *) mod_include cleanup showed that handle_else was being used to handle
8443 endif. It didn't cause problems, but it was cleaned up too.
8446 *) Last official synchronization of mod_rewrite with author version (because
8447 mod_rewrite is now directly developed by the author at the Apache Group):
8448 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8449 minus WIN32/NT stuff, but plus copyright removement.
8451 - workaround for detecting infinite rewriting loops
8452 - fixed setting of env vars when "-" is used as subst string
8453 - fixed forced response code on redirects (PR#777)

8455 - kludge to disable locking on pipes under braindead SunOS
8456 - fix for rewritelog in cases where remote hostname is unknown
8457 - fixed totally damaged request_rec walk-back loop
8458 o remove static from local data and add static to global ones.
8459 o replaced ugly proxy finding stuff by simple
8460 find_linked_module("mod_proxy") call.
8461 o added missing negation char on rewritelog()
8462 o fixed a few comment typos

8493 *) API: In HTTP/1.1, whether or not a request message contains a body
8494 is independent of the request method and based solely on the presence
8495 of a Content-Length or Transfer-Encoding. Therefore, our default
8496 handlers need to be prepared to read a body even if they don't know
8497 what to do with it; otherwise, the body would be mistaken for the

8510 symlinks, or directories. This prevents local users from using pipes
8511 or named sockets to invoke programs for an extremely crude form of
8514 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
8515 could contain "../" allowing a local user to "publish" any file on
8516 the system. No slashes are allowed now. [Dean Gaudet]
8518 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8519 (headers, readmes, titles), mod_negotiation (type maps), or
8520 mod_cern_meta (meta files). [Dean Gaudet]
8522 *) SECURITY: Apache will refuse to run as "User root" unless
8523 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8525 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8526 if it contained a .htaccess disallowing symlinks. This is contrary
8527 to the rule that symlink permissions are tested with the symlink
8528 options of the parent directory. [Dean Gaudet] PR#353
8530 *) CONFIG: The LockFile directive can be used to place the serializing
8531 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8532 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8535 *) Request processing now retains state of whether or not the request
8536 body has been read, so that internal redirects and subrequests will
8537 not try to read it twice (and block). [Roy Fielding]
8539 *) Add a placeholder in modules/Makefile to avoid errors with certain
8540 makes. [Marc Slemko]
8542 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
8543 [Dean Gaudet] PR#644
8545 *) mod_include was not properly changing the current directory.
8546 [Marc Slemko] PR#742
8548 *) Attempt to work around problems with third party libraries that do not
8549 handle high numbered descriptors (examples include bind, and
8550 solaris libc). On all systems apache attempts to keep all permanent
8551 descriptors above 15 (called the low slack line). Solaris users
8552 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8553 which keeps all non-FILE * descriptors above 255. On all systems
8554 this should make supporting large numbers of vhosts with many open
8555 log files more feasible. If this causes trouble please report it,
8556 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8557 [Dean Gaudet] various PRs
8559 *) Related to the last entry, network sockets are now opened before
8560 log files are opened. The only known case where this can cause
8561 problems is under Solaris with many virtualhosts and many Listen
8562 directives. But using -DHIGH_SLACK_LINE=256 described above will
8563 work around this problem. [Dean Gaudet]
8565 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8568 *) Improved unix error response logging. [Marc Slemko]
8570 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8571 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8572 when a URL http://... was used in conjunction with a special
8573 redirect flag, e.g. R=permanent, the permanent status was lost.
8574 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>, Ralf S. Engelschall]
8576 *) If an object has multiple variants that are otherwise equal Apache
8577 would prefer the last listed variant rather than the first.
8580 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
8582 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
8585 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]
8587 *) PORT: fix rlim_t problems with AIX 4.2. [Marc Slemko] PR#333
8589 *) PORT: Update UnixWare support for 2.1.2.
8590 [Lawrence Rosenman <ler@lerctr.org>] PR#511
8592 *) PORT: NonStop-UX [Joachim Schmitz <schmitz_joachim@tandem.com>] PR#327
8594 *) PORT: Update ConvexOS support for 11.5.
8595 [David DeSimone <fox@convex.com>] PR#399
8597 *) PORT: Support for DEC cc compiler under ULTRIX.
8598 ["P. Alejandro Lopez-Valencia" <alejolo@ideam.gov.co>] PR#388
8600 *) PORT: Support for Maxion/OS SVR4.2 Real Time Unix. [no name given] PR#383
8602 *) PORT: Workaround for AIX 3.x compiler bug in http_bprintf.c.
8603 [Marc Slemko] PR#725
8605 *) PORT: fix problem compiling http_bprintf.c with gcc under SCO
8606 [Marc Slemko] PR#695
8608 Changes with Apache 1.2
8610 Changes with Apache 1.2b11
8612 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
8614 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
8615 [Doug MacEachern, Rob Hartill]
8617 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
8618 reading from one buffer and writing to another, at least until it has
8619 a custom timeout handler. [Roy Fielding and Petr Lampa]
8621 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
8622 apparently due to a mismatch between sigaction and setjmp.
8623 [Roy Fielding] PR#502
8625 *) Log correct status code if we timeout before receiving a request (408)
8626 or if we received a request-line that was too long to process (414).
8627 [Ed Korthof and Roy Fielding] PR#601
8629 *) Virtual hosts with the same ServerName, but on different ports, were
8630 not being selected properly. [Ed Korthof]
8632 *) Added code to return the requested IP address from proxy_host2addr()
8633 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
8634 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8635 [Chuck Murcko] PR#614
8637 *) If multiple requests on a single connection are used to retrieve
8638 data from different virtual hosts, the virtual host list would be
8639 scanned starting with the most recently used VH instead of the first,
8640 causing most virtual hosts to be ignored.
8641 [Paul Sutton and Martin Mares] PR#610
8643 *) The OS/2 handling of process group was broken by a porting patch for
8644 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
8646 *) Inherit virtual server port from main server if none (or "*") is
8647 given for VirtualHost. [Dean Gaudet] PR#576
8649 *) If the lookup for a DirectoryIndex name with content negotiation
8650 has found matching variants, but none are acceptable, return the
8651 negotiation result if there are no more DirectoryIndex names to lookup.
8652 [Petr Lampa and Roy Fielding]
8654 *) If a soft_timeout occurs after keepalive is set, then the main child
8655 loop would try to read another request even though the connection
8656 has been aborted. [Roy Fielding]
8658 *) Configure changes: Allow for whitespace at the start of a
8659 Module declaration. Also, be more understanding about the
8660 CC=/OPTIM= format in Configuration. Finally, fix compiler
8661 flags if using HP-UX's cc compiler. [Jim Jagielski]
8663 *) Subrequests and internal redirects now inherit the_request from the
8664 original request-line. [Roy Fielding]
8666 *) Test for error conditions before creating output header fields, since
8667 we don't want the error message to include those fields. Likewise,
8668 reset the content_language(s) and content_encoding of the response
8669 before generating or redirecting to an error message, since the new
8670 message will have its own Content-* definitions. [Dean Gaudet]
8672 *) Restored the semantics of headers_out (headers sent only with 200..299
8673 and 304 responses) and err_headers_out (headers sent with all responses).
8674 Avoid the overhead of copying tables if err_headers_out is empty
8675 (the usual case). [Roy Fielding]
8677 *) Fixed a couple places where a check for the default Content-Type was
8678 not properly checking both the value configured by the DefaultType
8679 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8680 of DEFAULT_TYPE to match the documented default (text/plain).
8681 [Dean Gaudet] PR#506
8683 *) Escape the HTML-sensitive characters in the Request-URI that is
8684 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8686 *) Properly initialize the flock structures used by the mutex locking
8687 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8690 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8691 (and NCSA httpd) definition wherein it was the extra path info beyond
8692 the CGI script filename. The environment variable FILEPATH_INFO has
8693 been removed, and instead we supply the original REQUEST_URI to any
8694 script that wants to be Apache-specific and needs the real URI path.
8695 This solves a problem with existing scripts that use extra path info
8696 in the ScriptAlias directive to pass options to the CGI script.
8699 *) The _default_ change in 1.2b10 will change the behaviour on configs
8700 that use multiple Listen statements for listening on multiple ports.
8701 But that change is necessary to make _default_ consistent with other
8702 forms of <VirtualHost>. It requires such configs to be modified
8703 to use <VirtualHost _default_:*>. The documentation has been
8704 updated. [Dean Gaudet] PR#530
8706 *) If an ErrorDocument CGI script is used to respond to an error
8707 generated by another CGI script which has already read the message
8708 body of the request, the server would block trying to read the
8709 message body again. [Rob Hartill]
8711 *) signal() replacement conflicted with a define on QNX (and potentially
8712 other platforms). Fixed. [Ben Laurie] PR#512
8714 Changes with Apache 1.2b10
8716 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8717 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8719 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8721 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
8723 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
8724 config, in case the hostent struct returned is trash.
8725 [Chuck Murcko] PR #491
8727 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8728 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8730 Changes with Apache 1.2b9 [never announced]
8732 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8733 changes and in anticipation of 1.2 final release. [Roy Fielding]
8735 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8736 the connection (e.g., when user presses Stop). Apache will now stop
8737 trying to send a message body immediately after an error from write.
8738 [Roy Fielding and Nathan Kurz] PR#335
8740 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8741 than mod_alias, and mod_alias has higher priority than mod_proxy;
8742 rearranged other modules to enhance understanding of their purpose
8743 and relative order (and maybe even reduce some overhead).
8744 [Roy Fielding and Sameer Parekh]
8746 *) Fix graceful restart. Eliminate many signal-related race
8747 conditions in both forms of restart, and in SIGTERM. See
8748 htdocs/manual/stopping.html for details on stopping and
8749 restarting the parent. [Dean Gaudet]
8751 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8752 memory allocator to avoid a behaviour that required extra blocks to
8753 be allocated. [Dean Gaudet]
8755 *) Allow suexec to access files relative to current directory but not
8756 above. (Excluding leading / or any .. directory.) [Ken Coar]
8759 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8760 PR#367, 368, 354, 453
8762 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8763 while obtaining the /~user and save the username in a separate data
8764 area so that it won't be overwritten by the call to getgrgid(), and
8765 fix some misuse of the pool string allocation functions. Also fixes
8766 a general problem with parsing URL query info into args for CGI scripts.
8767 [Roy Fielding] PR#339, 367, 354, 453
8769 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
8771 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
8773 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
8774 AuthDBAuthoritative. [Marc Slemko] PR#420
8776 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8778 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8779 object that can't be PUT, or FOOBAR for some method FOOBAR that
8780 apache doesn't know about at all). Log 404s that occur in mod_include.
8781 [Paul Sutton, John Van Essen]
8783 *) If a soft timeout (or lingerout) occurs while trying to flush a
8784 buffer or write inside buff.c or fread'ing from a CGI's output,
8785 then the timeout would be ignored. [Roy Fielding] PR#373
8787 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8788 parsing of headers. If the terminating empty-line CRLF occurs starting
8789 at the 256th or 257th byte of output, then Navigator will think a normal
8790 image is invalid. We are guessing that this is because their initial
8791 read of a new request uses a 256 byte buffer. We check the bytes written
8792 so far and, if we are about to tickle the bug, we instead insert a
8793 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8795 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8796 of an external redirection. [Roy Fielding and Paul Sutton]
8798 *) Configure would create a broken Makefile if the configuration file
8799 contained a commented-out Rule. [Roy Fielding]
8801 *) Promote per_dir_config and subprocess_env from the subrequest to the
8802 main request in mod_negotiation. In particular this fixes a bug
8803 where <Files> sections wouldn't properly apply to negotiated content.
8806 *) Fix a potential deadlock in mod_cgi script_err handling.
8807 [Ralf S. Engelschall]
8809 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8812 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8813 .htaccess files because the RewriteBase was not replaced correctly.
8814 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8815 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8817 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8818 1.x the settings are those of pre-1.2b8. For 2.x we include
8819 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8820 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8821 [Dean Gaudet] PR#336, PR#340
8823 *) Redirect did not preserve ?query_strings when present in the client's
8824 request. [Dean Gaudet]
8826 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8828 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8830 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8832 *) Add mod_example (illustration of API techniques). [Ken Coar]
8834 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8836 *) Improve handling of directories when filenames have spaces in them.
8839 *) For hosts with multiple IP addresses, try all additional addresses if
8840 necessary to get a connect. Fail only if hostent address list is
8841 exhausted. [Chuck Murcko]
8843 *) More signed/unsigned port fixes. [Dean Gaudet]
8845 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8848 Changes with Apache 1.2b8
8850 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8851 to it. [Marc Slemko]
8853 *) The addition of <Location> and <File> directives made the
8854 sub_req_lookup_simple() function bogus, so we now handle
8855 the special cases directly. [Dean Gaudet]
8857 *) We now try to log where the server is dumping core when a fatal
8858 signal is received. [Ken Coar]
8860 *) Improved lingering_close by adding a special timeout, removing the
8861 spurious log messages, removing the nonblocking settings (they
8862 are not needed with the better timeout), and adding commentary
8863 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8864 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8866 *) Send error messages about setsockopt failures to the server error
8867 log instead of stderr. [Roy Fielding]
8869 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8871 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8872 processing a subrequest, allocate memory from r->main->pool instead
8873 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8874 in the middle of an SSI request. [Dean Gaudet] PR #122
8876 *) Fixed status of response when POST is received for a nonexistent URL
8877 (was sending 405, now 404) and when any method is sent with a
8878 full-URI that doesn't match the server and the server is not acting
8879 as a proxy (was sending 501, now 403). [Roy Fielding]
8881 *) Host port changed to unsigned short. [Ken Coar] PR #276
8883 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8885 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8887 *) Report extra info from errno with many errors that cause httpd to exit.
8888 spawn_child, popenf, and pclosef now have valid errno returns in the
8889 event of an error. Correct problems where errno was stomped on
8890 before being reported. [Dean Gaudet]
8892 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8893 never called, and thus the filesystem would remain full indefinitely.
8894 We now also remove incomplete cache files left if the origin server
8895 didn't send a Content-Length header and either the client has aborted
8896 transfer or bwrite() to client has failed. [Petr Lampa]
8898 *) Fixed the handling of module and script-added header fields.
8899 Improved the interface for sending header fields and reduced
8900 the duplication of code between sending okay responses and errors.
8901 We now always send both headers_out and err_headers_out, and
8902 ensure that the server-reserved fields are not being overridden,
8903 while not overriding those that are not reserved. [Roy Fielding]
8905 *) Moved transparent content negotiation fields to err_headers_out
8906 to reflect above changes. [Petr Lampa]
8908 *) Fixed the determination of whether or not we should make the
8909 connection persistent for all of the cases where some other part
8910 of the server has already indicated that we should not. Also
8911 improved the ordering of the test so that chunked encoding will
8912 be set whenever it is desired instead of only when KeepAlive
8913 is enabled. Added persistent connection capability for most error
8914 responses (those that do not indicate a bad input stream) when
8915 accessed by an HTTP/1.1 client. [Roy Fielding]
8917 *) Added missing timeouts for sending header fields, error responses,
8918 and the last chunk of chunked encoding, each of which could have
8919 resulted in a process being stuck in write forever. Using soft_timeout
8920 requires that the sender check for an aborted connection rather than
8921 continuing after an EINTR. Timeouts that used to be initiated before
8922 send_http_header (and never killed) are now initiated only within or
8923 around the routines that actually do the sending, and not allowed to
8924 propagate above the caller. [Roy Fielding]
8926 *) mod_auth_anon required an @ or a . in the email address, not both.
8929 *) per_dir_defaults weren't set correctly until directory_walk for
8930 name-based vhosts. This fixes an obscure bug with the wrong config
8931 info being used for vhosts that share the same ip as the server.
8934 *) Improved generation of modules/Makefile to be more generic for
8935 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8937 *) Generate makefile dependency for Configuration based on the actual
8938 name given when running the Configure process. [Dean Gaudet]
8940 *) Fixed problem with vhost error log not being set prior to
8941 initializing virtual hosts. [Dean Gaudet]
8943 *) Fixed infinite loop when a trailing slash is included after a type map
8944 file URL (extra path info). [Petr Lampa]
8946 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8948 *) Add documentation for DNS issues (reliability and security), and try
8949 to explain the virtual host matching process. [Dean Gaudet]
8951 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8952 fails while parsing the configuration file. [Dean Gaudet]
8954 *) Improved calls to setsockopt. [Roy Fielding]
8956 *) Negotiation changes: Don't output empty content-type in variant list;
8957 Output charset in variant list; Return sooner from handle_multi() if
8958 no variants found; Add handling of '*' wildcard in Accept-Charset.
8959 [Petr Lampa and Paul Sutton]
8961 *) Fixed overlaying of request/sub-request notes and headers in
8962 mod_negotiation. [Dean Gaudet]
8964 *) If two variants' charset quality are equal and one is the default
8965 charset (iso-8859-1), then prefer the variant that was specifically
8966 listed in Accept-Charset instead of the default. [Petr Lampa]
8968 *) Memory allocation problem in push_array() -- it would corrupt memory
8969 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8971 *) invoke_handler() doesn't handle mime arguments in content-type
8974 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8977 *) Fixed problem with ErrorDocument not working for virtual hosts
8978 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8980 *) Log an error message if we get a request header that is too long,
8981 since it may indicate a buffer overflow attack. [Marc Slemko]
8983 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8984 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8985 [Ken Coar] PR #146, #187
8987 *) Added table entry placeholder for new header_parser callback
8988 in all of the distributed modules. [Ken Coar] PR #191
8990 *) Allow for cgi files without the .EXE extension on them under OS/2.
8991 [Garey Smiley] PR #59
8993 *) Fixed error message when resource is not found and URL contains
8994 path info. [Petr Lampa and Dean Gaudet] PR #40
8996 *) Fixed user and server confusion over what should be a virtual host
8997 and what is the main server, resulting in access to something
8998 other than the name defined in the virtualhost directive (but
8999 with the same IP address) failing. [Dean Gaudet]
9001 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
9002 AIX; improves the redirection stuff to enable the users to generally
9003 redirect to http, https, gopher and ftp; added TIME variable for
9004 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
9005 special patterns >STRING, <STRING and =STRING to RewriteCond, which
9006 can be used in conjunction with %{TIME} or other variables to create
9007 time-dependent rewriting rules. [Ralf S. Engelschall]
9009 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
9010 Module authors may need to adjust their code for proper cleanup to take
9011 place (that is, call note_cleanups_for_fd()). This change fixes problems
9012 with file descriptors being erroneously closed when the proxy module was
9013 in use. [Ben Laurie]
9015 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
9016 initgroups() to hose the group information needed for later
9017 comparisons. [Randy Terbush]
9019 *) Remove unnecessary call to va_end() in create_argv() which
9020 caused a SEGV on some systems.
9022 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
9025 *) Clear memory allocated for listeners. [Randy Terbush]
9027 *) Improved handling of IP address as a virtualhost address and
9028 introduced "_default_" as a synonym for the default vhost config.

9048 - Changed send_dir() to remove user/passwd from displayed URL.
9049 - Changed login error messages to be more descriptive.
9050 - remove setting of SO_DEBUG socket option
9051 - Make ftp_getrc() more lenient about multiline responses,
9052 specifically, 230 responses which don't have continuation 230-
9053 on each line). These seem to be all NT FTP servers, and while
9054 perhaps questionable, they appear to be legal by RFC 959.
9055 - Add missing kill_timeout() after transfer to user completes.
9058 *) Fixed problem where a busy server could hang when restarting
9059 after being sent a SIGHUP due to child processes not exiting.
9062 *) Modify mod_include escaping so a '\' only signifies an escaped
9063 character if the next character is one that needs
9064 escaping. [Ben Laurie]
9066 *) Eliminated possible infinite loop in mod_imap when relative URLs are
9067 used with a 'base' directive that does not have a '/' in it.
9068 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
9070 *) Reduced the default timeout from 1200 seconds to 300, and the
9071 one in the sample configfile from 400 to 300. [Marc Slemko]
9073 *) Stop vbprintf from crashing if given a NULL string pointer;
9074 print (null) instead. [Ken Coar]
9076 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
9077 [Marc Slemko and Roy Fielding]
9079 *) Fixed problem with mod_cgi-generated internal redirects trying to
9080 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9082 *) Reduced timeout on lingering close, removed possibility of a blocked
9083 read causing the child to hang, and stopped logging of errors if
9084 the socket is not connected (reset by client). [Roy Fielding]
9086 *) Rearranged main child loop to remove duplication of code in
9087 select/accept and keep-alive requests, fixed several bugs regarding
9088 checking scoreboard_image for exit indication and failure to
9089 account for all success conditions and trap all error conditions,
9090 prevented multiple flushes before closing the socket; close the entire
9091 socket buffer instead of just one descriptor, prevent logging of
9092 EPROTO and ECONNABORTED on platforms where supported, and generally
9093 improved readability. [Roy Fielding]
9095 *) Extensive performance improvements. Cleaned up inefficient use of
9096 auto initializers, multiple is_matchexp calls on a static string,
9097 and excessive merging of response_code_strings. [Dean Gaudet]
9099 *) Added double-buffering to mod_include to improve performance on
9100 server-side includes. [Marc Slemko]
9102 *) Several fixes for suexec wrapper. [Randy Terbush]
9103 - Make wrapper work for files on NFS filesystem.
9104 - Fix portability problem of MAXPATHLEN.
9105 - Fix array overrun problem in clean_env().
9106 - Fix allocation of PATH environment variable
9108 *) Removed extraneous blank line is description of mod_status chars.
9111 *) Logging of errors from the call_exec routine simply went nowhere,
9112 since the logfile fd has been closed, so now we send them to stderr.
9113 [Harald T. Alvestrand]
9115 *) Fixed core dump when DocumentRoot is a CGI.
9116 [Ben Laurie, reported by geddis@tesserae.com]
9118 *) Fixed potential file descriptor leak in mod_asis; updated it and
9119 http_core to use pfopen/pfclose instead of fopen/fclose.
9120 [Randy Terbush and Roy Fielding]
9122 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9123 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9124 [Dean Gaudet and Ken Coar]
9126 *) Return a 302 response code to the client when sending a redirect
9127 due to a missing trailing '/' on a directory instead of a 301; now
9128 it is cacheable. [Markus Gyger]
9130 *) Fix condition where, if a bad directive occurs in .htaccess, and
9131 sub_request() goes first to this directory, then log_reason() will
9132 SIGSEGV because it doesn't have initialized r->per_dir_config.
9133 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9135 *) Fix handling of lang_index in is_variant_better(). This was
9136 causing problems which resulted in the server sending the
9137 wrong language document in some cases. [Petr Lampa]
9139 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9140 the clean environment on some systems.
9142 *) Tweak byteserving code (e.g. serving PDF files) to work around
9143 bugs in Netscape Navigator and Microsoft Internet Explorer.
9144 Emit Content-Length header when sending multipart/byteranges.
9147 *) Port to HI-UX/WE2. [Nick Maclaren]
9149 *) Port to HP MPE operating system for HP 3000 machines
9150 [Mark Bixby <markb@cccd.edu>]
9152 *) Fixed bug which caused a segmentation fault if only one argument
9153 given to RLimit* directives. [Ed Korthof]
9155 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9157 *) Improved buffered output to the client by delaying the flush decision
9158 until the BUFF code is actually about to read the next request.
9159 This fixes a problem introduced in 1.2b5 with clients that send
9160 an extra CRLF after a POST request. Also improved chunked output
9161 performance by combining writes using writev() and removing as
9162 many bflush() calls as possible. NOTE: Platforms without writev()
9163 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9164 or Configure, unless we have already done so. [Dean Gaudet]
9166 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9168 *) Fixed mod_info output corruption bug introduced by buffer overflow
9169 fixes. [Dean Gaudet]
9171 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9172 for the special case of a 304 response. [Paul Sutton]
9174 *) Improved handling of TRACE method by bypassing normal method handling
9175 and header parsing routines; fixed Allow response to always allow TRACE.
9178 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9180 *) Cleaned-up some of the generated HTML. [Ken Coar]
9182 Changes with Apache 1.2b6
9184 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9186 *) Fix typo introduced in fix for potential infinite loop around
9187 accept() in child_main(). This change caused the rev to 1.2b6.
9188 1.2b5 was never a public beta.
9190 Changes with Apache 1.2b5
9192 *) Change KeepAlive semantics (On|Off instead of a number), add
9193 MaxKeepAliveRequests directive. [Alexei Kosut]
9195 *) Various NeXT compilation patches, as well as a change in
9196 regex/regcomp.c since that file also used a NEXT define.
9199 *) Allow * to terminate the end of a directory match in mod_dir.
9200 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9202 *) Don't call can_exec() if suexec_enabled. Calling this requires
9203 scripts executed by the suexec wrapper to be world executable, which
9204 defeats one of the advantages of running the wrapper. [Randy Terbush]
9206 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9209 *) Migration from sprintf() to snprintf() to avoid buffer
9210 overflows. [Marc Slemko]
9212 *) Provide portable snprintf() implementation (ap_snprintf)
9213 as well as *cvt family. [Jim Jagielski]
9215 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9218 *) Remove mod_fastcgi.c from the distribution. This module appears
9219 to be maintained more through the Open Market channels and should
9220 continue to be easily available at http://www.fastcgi.com/
9222 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9223 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9225 *) mod_info assumed that the config files were relative to ServerRoot.
9228 *) CGI scripts called as an error document resulting from failed
9229 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9231 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9234 *) Properly check errno to prevent display of a directory index
9235 when server receives a long enough URL to confuse stat().
9238 *) Several security enhancements to suexec wrapper. It is _highly_
9239 recommended that previously installed versions of the wrapper
9240 be replaced with this version. [Randy Terbush, Jason Dour]
9242 - ~user execution now properly restricted to ~user's home
9243 directory and below.
9244 - execution restricted to UID/GID > 100
9245 - restrict passed environment to known variables
9246 - call setgid() before initgroups() (portability fix)
9247 - remove use of setenv() (portability fix)
9249 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9251 *) Add access control via environment variables. [Ben Laurie]
9253 *) Add rflush() function. [Alexei Kosut]
9255 *) remove duplicate pcalloc() call in new_connection().
9257 *) Fix incorrect comparison which could allow number of children =
9258 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9259 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9261 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9262 AIX PS/2, CONVEXOS. [Jim Jagielski]
9264 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9265 It's more portable. [Martin Kraemer]
9267 *) Replace references to make in Makefile.tmpl with $(MAKE).
9270 *) Add ProxyBlock directive w/IP address caching. Add IP address
9271 caching to NoCache directive as well. ProxyBlock works with all
9272 handlers; NoCache now also works with FTP for anonymous logins.
9273 Still more code cleanup. [Chuck Murcko]
9275 *) Add "header parse" API hook [Ben Laurie]
9277 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9279 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9281 *) Correctly allow access and auth directives in <Files> sections in
9282 server config files. [Alexei Kosut]
9284 *) Fix bug with ServerPath that could cause certain files to be not
9285 found by the server. [Alexei Kosut]
9287 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9288 double-quote from text and so that it properly checks for unsupported
9289 status codes using the new index_of_response interface. [Roy Fielding]
9291 *) Multiple fixes to the lingering_close code in order to avoid being
9292 interrupted by a stray timeout, to avoid lingering on a connection
9293 that has already been aborted or never really existed, to ensure that
9294 we stop lingering as soon as any error condition is received, and to
9295 prevent being stuck indefinitely if the read blocks. Also improves
9296 reporting of error conditions. [Marc Slemko and Roy Fielding]
9298 *) Fixed initialization of parameter structure for sigaction.
9299 [mgyger@itr.ch, Adrian Filipi-Martin]
9301 *) Fixed reinitializing the parameters before each call to accept and
9302 select, and removed potential for infinite loop in accept.
9303 [Roy Fielding, after useful PR from adrian@virginia.edu]
9305 *) Fixed condition where, if a child fails to fork, the scoreboard would
9306 continue to say SERVER_STARTING forever. Eventually, the main process
9307 would refuse to start new children because count_idle_servers() will
9308 count those SERVER_STARTING entries and will always report that there
9309 are enough idle servers. [Phillip Vandry]
9311 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9312 Avoided calling bflush() when the client is pipelining requests.
9313 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9315 *) Added description of "." mode in server-status [Jim Jagielski]
9317 Changes with Apache 1.2b4
9319 *) Fix possible race condition in accept_mutex_init() that
9320 could leave a small security hole open allowing files to be
9321 overwritten in cases where the server UID has write permissions.
9324 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9326 *) Fix portablity problem in util_script where ARG_MAX may not be
9327 defined for some systems.
9329 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9332 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9333 style magic #! token for better script portability. [Garey Smiley]
9335 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9336 execution for ~userdir CGI. [Jason Dour]
9338 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9340 *) Fix month off by one in suexec wrapper logging.
9342 Changes with Apache 1.2b3:
9344 *) Fix error in mod_cgi which could cause resources not to be properly
9345 freed, or worse. [Dean Gaudet]
9347 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9349 *) Add set_flag_slot() at the request of Dirk and others.
9352 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9354 *) Add changes to improve the error message given for invalid
9355 ServerName parameters. [Dirk vanGulik]
9357 *) Add "Authoritative" directive for Auth modules that don't
9358 currently have it. This gives admin control to assign authoritative
9359 control to an authentication scheme and allow "fall through" for
9360 those authentication modules that aren't "Authoritative" thereby
9361 allowing multiple authentication mechanisms to be chained.
9364 *) Remove requirement for ResourceConfig/AccessConfig if not using
9365 the three config file layout. [Randy Terbush]
9367 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9369 *) Changes to suexec wrapper to fix the following problems:
9370 1. symlinked homedirs will kill ~userdirs.
9371 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9372 3. CGI command lines paramters problems
9373 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9374 [Randy Terbush, Jason Dour]
9376 *) Change create_argv() to accept variable arguments. This fixes
9377 a problem where arguments were not getting passed to the CGI via
9378 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9380 *) Collapse multiple slashes in path URLs to properly apply
9381 handlers defined by <Location>. [Alexei Kosut]
9383 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9385 *) Improve the accuracy of request duration timings by setting
9386 r->request_time in read_request_line() instead of read_request().
9389 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9390 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9392 *) Add the ability to pass different Makefile.tmpl files to Configure
9393 using the -make flag. [Rob Hartill]
9395 *) Fix coredump triggered when sending a SIGHUP to the server caused
9396 by an assertion failure, in turn caused by an uninitialised field in a
9400 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9401 PATH_INFO from previous versions of Apache (in certain situations,
9402 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9403 [later removed in 1.2b11]
9405 *) Add rwrite() function to API to allow for sending strings of
9406 arbitrary length. [Doug MacEachern]
9408 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9410 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9411 NeXT. [Jim Jagielski]
9413 *) Removed recent modification to promote the status code on internal
9414 redirects, since the correct fix was to change the default log format
9415 in mod_log_config so that it outputs the original status. [Rob Hartill]
9417 Changes with Apache 1.2b2:
9419 *) Update set_signals() to use sigaction() for setting handlers.
9420 This appears to fix a re-entrant problem in the seg_fault()
9421 bus_error() handlers. [Randy Terbush]
9423 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9425 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9427 *) proxy_http.c bugfixes: [Chuck Murcko]
9428 1) fixes possible NULL pointer reference w/NoCache
9429 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9430 host would cache nothing if it was in the local domain,
9431 and the local domain was in the NoCache list)
9432 3) Adds Host: header when not available
9433 4) Some code cleanup and clarification
9435 *) mod_include.c bugfixes:
9436 1) Fixed an ommission that caused include variables to not
9437 be parsed in config errmsg directives [Howard Fear]
9438 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9439 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9440 4) Allow backslash-escaping to all quoted text
9441 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9442 5) Pass variable to command line if not set in XSSI's env
9445 *) Fix infinite loop when processing Content-language lines in
9446 type-map files. [Alexei Kosut]
9448 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9450 *) Fixed problem in set_[user|group] that prevented CGI execution
9451 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9453 *) Added PORTING information file. [Jim Jagielski]
9455 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9457 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9459 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9460 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9462 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9463 which caused problems of systems where socket s_addr is >32bits.
9465 *) Added comment to explain (r->chunked = 1) side-effect in
9466 http_protocol.c [Roy Fielding]
9468 *) Replaced use of index() in mod_expires.c with more appropriate
9469 and portable isdigit() test. [Ben Laurie]
9471 *) Updated Configure for ...
9472 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9473 *-dg-dgux* (bad pattern match)
9474 QNX (DEF_WANTHSREGEX=yes)
9475 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9478 and added some user diagnostic info. [Ben Laurie]
9480 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9481 for better portability. [Jim Jagielski]
9483 *) Updated helpers/GuessOS for ...
9484 SCO 5 (recognize minor releases)
9485 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9486 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9487 IRIX64 (-sgi-irix64)
9488 ULTRIX (-unknown-ultrix)
9489 SINIX (-whatever-sysv4)
9490 NCR Unix (-ncr-sysv4)
9491 and fixed something in helpers/PrintPath [Ben Laurie]
9493 Changes with Apache 1.2b1
9495 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9497 Changes with Apache 1.1.1
9499 *) Fixed bug where Cookie module would make two entries in the
9500 logfile for each access [Mark Cox]
9502 *) Fixed bug where Redirect in .htaccess files would cause memory
9503 leak. [Nathan Neulinger]
9505 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9507 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9509 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9511 Changes with Apache 1.1.0
9513 *) Bring NeXT support up to date. [Takaaki Matsumoto]

9517 *) Make virtual hosts default to main server keepalive parameters.
9518 [Alexei Kosut, Ben Laurie]
9520 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9522 *) Fix missing address family for connect, also remove unreachable statement
9523 in mod_proxy. [Ben Laurie]
9525 *) mod_env now turned on by default in Configuration.tmpl.
9527 *) Bugs which were fixed:
9528 a) yet more mod_proxy bugs [Ben Laurie]
9529 b) CGI works again with inetd [Alexei Kosut]
9530 c) Leading colons were stripped from passwords [osm@interguide.com]
9531 d) Another fix to multi-method Limit problem [jk@tools.de]
9533 Changes with Apache 1.1b4
9535 *) r->bytes_sent variable restored. [Robert Thau]
9537 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9539 *) More possibly unsecure programs removed from the support directory.
9541 *) More mod_auth_msql authentication improvements.
9543 *) VirtualHosts based on Host: headers no longer conflict with the
9546 *) OS/2 compatibility enhancements. [Gary Smiley]
9548 *) POST now allowed to directory index CGI scripts.
9550 *) Actions now work with files of the default type.
9552 *) Bugs which were fixed:
9553 a) more mod_proxy bugs
9554 b) early termination of inetd requests
9555 c) compile warnings on several systems
9556 d) problems when scripts stop reading output early
9558 Changes with Apache 1.1b3
9560 *) Much of cgi-bin and all of cgi-src has been removed, due to
9561 various security holes found and that we could no longer support
9564 *) The "Set-Cookie" header is now special-cased to not merge multiple
9565 instances, since certain popular browsers can not handle multiple
9566 Set-Cookie instructions in a single header. [Paul Sutton]
9568 *) rprintf() added to buffer code, occurrences of sprintf removed.
9571 *) CONNECT method for proxy module, which means tunneling SSL should work.
9572 (No crypto needed) Also a NoCache config directive.
9574 *) Several API additions: pstrndup(), table_unset() and get_token()
9575 functions now available to modules.
9577 *) mod_imap fixups, in particular Location: headers are now complete
9580 *) New "info" module which reports on installed module set through a
9581 special URL, a la mod_status.
9583 *) "ServerPath" directive added - allows for graceful transition
9584 for Host:-header-based virtual hosts.
9586 *) Anonymous authentication module improvements.
9588 *) MSQL authentication module improvements.
9590 *) Status module design improved - output now table-based. [Ben Laurie]
9592 *) htdigest utility included for use with digest authentication
9595 *) mod_negotiation: Accept values with wildcards to be treated with
9596 less priority than those without wildcards at the same quality
9597 value. [Alexei Kosut]
9599 *) Bugs which were fixed:
9600 a) numerous mod_proxy bugs
9601 b) CGI early-termination bug [Ben Laurie]
9602 c) Keepalives not working with virtual hosts
9603 d) RefererIgnore problems
9604 e) closing fd's twice in mod_include (causing core dumps on
9605 Linux and elsewhere).
9607 Changes with Apache 1.1b2
9610 a) core dumps in mod_digest
9611 b) truncated hostnames/ip address in the logs
9612 c) relative URL's in mod_imap map files
9614 Changes with Apache 1.1b1
9616 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9618 Changes with Apache 1.0.3
9620 *) Internal redirects which occur in mod_dir.c now preserve the
9621 query portion of a request (the bit after the question mark).
9624 *) Escape active characters '<', '>' and '&' in html output in
9625 directory listings, error messages and redirection links.
9628 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9630 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9633 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9635 *) Reset timeout timer after each successful fwrite() to the network.
9636 This patch adds a reset_timeout() procedure that is called by
9637 send_fd() to reset the timeout ever time data is written to the net.
9640 *) timeout() signal handler now checks for SIGPIPE and reports
9641 lost connections in a more user friendly way. [Rob Hartill]
9643 *) Location of the "scoreboard" file which used to live in /tmp is
9644 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9645 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9647 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9649 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9650 which caused a SEGV with cookies enabled
9652 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9655 *) Log the UNIX textual error returned by some system calls, in
9656 particular errors from accept() [David Robinson]
9658 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9660 Changes with Apache 1.0.2
9662 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9663 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9665 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9668 *) past changes to http_config.c to only use the
9669 setrlimit function on systems defining RLIMIT_NOFILE
9670 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9671 for SUNOS and prototypes the needed functions.
9673 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9676 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9678 *) Merge multiple headers from CGI scripts instead of taking last
9679 one. [David Robinson]
9681 *) Add support for SCO 5. [Ben Laurie]
9683 Changes with Apache 1.0.1
9685 *) Silence mod_log_referer and mod_log_agent if not configured
9688 *) Recursive includes can occur if the client supplies PATH_INFO data
9689 and the server provider uses relative links; as file.html
9690 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9692 *) The replacement for initgroups() did not call {set,end}grent(). This
9693 had two implications: if anything else used getgrent(), then
9694 initgroups() would fail, and it was consuming a file descriptor.
9697 *) On heavily loaded servers it was possible for the scoreboard to get
9698 out of sync with reality, as a result of a race condition.
9699 The observed symptoms are far more Apaches running than should
9700 be, and heavy system loads, generally followed by catastrophic
9701 system failure. [Ben Laurie]
9703 *) Fix typo in license. [David Robinson]
9705 Changes with Apache 1.0.0 23 Nov 1995
9707 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9709 Changes with Apache 0.8.16 05 Nov 1995
9711 *) New man page for 'httpd' added to support directory [David Robinson]
9713 *) .htgroup files can have more than one line giving members for a
9714 given group (each must have the group name in front), for NCSA
9715 back-compatibility [Robert Thau]
9717 *) Mutual exclusion around accept() is on by default for SVR4 systems
9718 generally, since they generally can't handle multiple processes in
9719 accept() on the same socket. This should cure flaky behavior on
9720 a lot of those systems. [David Robinson]
9722 *) AddType, AddEncoding, and AddLanguage directives take multiple
9723 extensions on a single command line [David Robinson]
9725 *) UserDir can be disabled for a given virtual host by saying
9726 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9727 that this didn't work. [David Robinson]
9729 *) Compiles on QNX [Ben Laurie]
9731 *) Corrected parsing of ctime time format [David Robinson]
9733 *) httpd does a perror() before exiting if it can't log its pid
9734 to the PidFile, to make diagnosing the error a bit easier.
9737 *) <!--#include file="..."--> can no longer include files in the
9738 parent directory, for NCSA back-compatibility. [David Robinson]
9740 *) '~' is *not* escaped in URIs generated for directory listings
9743 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9745 *) Fixed bug involving handling URIs with escaped %-characters
9746 in redirects [David Robinson]
9748 Changes with Apache 0.8.15 14 Oct 1995
9750 *) Switched to new, simpler license
9752 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9754 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9756 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9758 *) Correctly handles internal redirects to files with names containing '%'
9761 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9763 *) Use geteuid() rather than getuid() to see if we have root privilege,
9764 so that server correctly resets privilege if run setuid root. [Andrew
9767 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9770 *) Fix relative URLs in imagemap files [Randy Terbush]
9772 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9775 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9776 entries all name the same one. [David Robinson]
9778 *) Fix directory listings with filenames containing unusual characters
9781 *) Better URI-escaping for generated URIs in directories with filenames
9782 containing unusual characters [Ben Laurie]
9784 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9786 *) Unblock alarms on error return from spawn_child() [David Robinson]
9788 *) Sample Config files have extra note for SCO users [Ben Laurie]
9790 *) Configuration has note for HP-UX users [Rob Hartill]
9792 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9794 *) Nuked bogus #define in httpd.h [David Robinson]
9796 *) Better test for whether a system has setrlimit() [David Robinson]
9798 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9800 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9803 Changes with Apache 0.8.14 19 Sep 1995
9805 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9807 *) AddDescription works (better) [Ben Laurie]
9809 *) Leaves an intelligible error diagnostic when it can't set group
9810 privileges on standalone startup [Andrew Wilson]
9812 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9813 that machine, which claims to be BSD but does not support RLIMIT.
9816 *) gcc -Wall no longer complains about an unused variable when util.c
9817 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9819 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9821 Changes with Apache 0.8.13 07 Sep 1995
9823 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9825 *) Have built-in imagemap code recognize & honor Point directive [James
9828 *) Generate cleaner directory listings in directories with a mix of
9829 long and short filenames [Rob Hartill]
9831 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9833 *) Properly default ServerName for virtual servers [Robert Thau]
9835 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9836 Paul Richards and a cast of thousands...]
9838 *) On self-identified BSD systems (we don't try to guess any more),
9839 allocate a few extra file descriptors per virtual host with setrlimit,
9840 if we can, to avoid running out. [Randy Terbush]
9842 *) Write 22-character lock file name into buffer with enough space
9843 on startup [Konstantin Olchanski]
9845 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9848 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9850 *) Suppress -Wall warning by initializing variable in negotiation code
9851 [Tobias Weingartner]
9853 Changes with Apache 0.8.12 31 Aug 1995
9855 *) Doesn't pause three seconds after including a CGI script which is
9856 too slow to die off (this is done by not even trying to kill off
9857 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9858 after the entire document has been processed). [Robert Thau]
9860 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9862 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9864 *) Allows .htaccess files to override <Directory> sections naming the
9865 same directory [David Robinson]
9867 *) Removed an efficiency hack in sub_req_lookup_uri which was
9868 causing certain extremely marginal cases (e.g., ScriptAlias of a
9869 *particular* index.html file) to fail. [David Robinson]
9871 *) Doesn't log an error when the requested URI requires
9872 authentication, but no auth header line was supplied by the
9873 client; this is a normal condition (the client doesn't no auth is
9874 needed here yet). [Robert Thau]
9876 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9878 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9880 *) RFC931 code no longer passes out name of prior clients on current
9881 requests if the current request came from a server that doesn't
9882 do RFC931. [David Robinson]
9884 *) Configuration script accepts "Module" lines with trailing whitespace.
9887 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9889 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9891 Changes with Apache 0.8.11 24 Aug 1995
9893 *) Wildcard <Directory> specifications work. [Robert Thau]
9895 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9897 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9898 the file being requested itself, in addition to the directories leading
9899 up to it. [Robert Thau]
9901 *) Logs access failures due to symlink checks or invalid client address
9902 in the error log [Roy Fielding, Robert Thau]
9904 *) Symlink checks deal correctly with systems where lstat of
9905 "/path/to/some/link/" follows the link. [Thau, Fielding]
9907 *) Doesn't reset DirectoryIndex to 'index.html' when
9908 other directory options are set in a .htaccess file. [Robert Thau]
9910 *) Clarified init code and nuked bogus warning in mod_access.c
9913 *) Corrected several directives in sample srm.conf
9914 --- includes corrections to directory indexing icon-related directives
9915 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9916 icons for encodings right, and turning on AddEncoding by default).
9919 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9922 *) INSTALL & README mention "contributed modules" directory [Brian
9925 *) Fixed English in the license language... "for for" --> "for".
9928 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9929 mod_alias.c, merging it almost completely with handling of Alias, and
9930 adding a 'notes' field to the request_rec which allows the CGI module
9931 to discover whether the Alias module has put this request through
9932 ScriptAlias (which it needs to know for back-compatibility, as the old
9933 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9936 Changes with Apache 0.8.10 18 Aug 1995
9938 *) AllowOverride applies to the named directory, and not just
9939 subdirectories. [David Robinson]
9941 *) Do locking for accept() exclusion (on systems that need it)
9942 using a special file created for the purpose in /usr/tmp, and
9943 not the error log; using the error log causes real problems
9944 if it's NFS-mounted; this is known to be the cause of a whole
9945 lot of "server hang" problems with Solaris. [David Robinson;
9946 thanks to Merten Schumann for help diagnosing the problem].
9948 Changes with Apache 0.8.9 12 Aug 1995
9950 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9952 *) Nested includes see environment variables of the including document,
9953 for NCSA bug-compatibility (some sites have standard footer includes
9954 which try to print out the last-modified date). [Eric Hagberg/Robert
9957 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9958 URI as a CGI script, even if it would have been treated as something
9959 else if requested directly, for NCSA back-compatibility. (Note that
9960 this means that people who know the name of the script can see the
9961 code just by asking for it). [Robert Thau]
9963 *) New version of dbmmanage script included in support directory as
9966 *) Check if scoreboard file couldn't be opened, and say so, rather
9967 then going insane [David Robinson]
9969 *) POST to CGI works on A/UX [Jim Jagielski]
9971 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9973 *) NCSA server push works properly --- the Arena bug compatibility
9974 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9975 if you still want the workaround). [Rob Hartill]
9977 *) If client didn't submit any Accept-encodings, ignore encodings in
9978 content negotiation. (NB this will all have to be reworked anyway
9979 for the new HTTP draft). [Florent Guillaume]
9981 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9983 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9985 *) Give Redirect priority over Alias, for NCSA bug compatibility
9988 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9989 paralleling earlier bug fix for CGI [David Robinson]
9991 *) If DBM auth is improperly configured, report a server error and don't
9994 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9995 it seems to work well enough without it (even in a 10 hits/sec
9996 workout), and the overhead for the locking under A/UX is
9997 alarmingly high (though it is very low on other systems).
9998 [Eric Hagberg, Jim Jagielski]
10000 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
10002 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
10003 Behlendorf/Eric Hagberg]
10005 *) More improvements to default Configuration for A/UX [Jim Jagielski]
10007 *) Compiles clean on NEXT [Rob Hartill]
10009 *) Compiles clean on SGI [Robert Thau]
10011 Changes with Apache 0.8.8 08 Aug 1995
10013 *) SunOS library prototypes now never included unless explicitly
10014 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
10015 people using GNU libc on SunOS are screwed by prototypes for the
10018 (Those who wish to compile clean with gcc -Wall on a standard
10019 SunOS setup need the prototypes, and may obtain them using
10020 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
10021 with nonstandard libraries are presumably competent to make their
10024 *) Strips trailing '/' characters off both args to the Alias command,
10025 to make 'Alias /foo/ /bar/' work.
10027 Changes with Apache 0.8.7 03 Aug 1995
10029 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
10030 [reported by David Robinson]
10032 *) Compiles clean on OSF/1 [David Robinson]
10034 *) Added some of the more recent significant changes (AddLanguage stuff,
10035 experimental LogFormat support) to CHANGES file in distribution root
10038 Changes with Apache 0.8.6 02 Aug 1995
10040 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10041 (If you actually wanted a conditional GET which bypassed the cache, you
10042 couldn't get it). [Reported by Roy Fielding]
10044 *) Properly terminate headers on '304 Not Modified' replies to conditional
10045 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10046 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10048 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10050 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10051 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10052 and older versions don't set the __SUNPRO_C preprocessor variable). On
10053 all other systems, these are never used anyway. [Reported by Mark Cox].
10055 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10057 Changes with Apache 0.8.5 01 Aug 1995
10059 *) Added last-minute configurable log experiment, as optional module
10061 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10062 properly. (One-line fix to http_protocol.c).
10064 *) Work around bogus behavior when reloading from Netscape.
10065 It's Netscape's bug --- for some reason they expect a request with
10066 If-modified-since: to not function as a conditional GET if it also
10067 comes with Pragma: no-cache, which is way out of line with the HTTP
10068 spec (according to Roy Fielding, the redactor).
10070 *) Added parameter to set maximum number of server processes.
10072 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10075 *) IdentityCheck bugfix [Chuck Murcko].
10077 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10079 *) More sample config file corrections; add extension to AddType for
10080 *.asis, move AddType generic description to its proper place, and
10081 fix miscellaneous typos. [ Alexei Kosut ]
10083 *) Deleted the *other* reference to the regents from the Berkeley
10084 legal disclaimer (everyplace).
10086 *) Nuked Shambhala name from src/README; had already cleaned it out
10087 of everywhere else.
10089 Changes with Apache 0.8.4
10091 *) Changes to server-pool management parms --- renamed current
10092 StartServers to MinSpareServers, created separate StartServers
10093 parameter which means what it says, and renamed MaxServers to
10094 MaxSpareServers (though the old name still works, for NCSA 1.4
10095 back-compatibility). The old names were generally regarded as
10096 too confusing. Also altered "docs" in sample config files.
10098 *) More improvements to default config files ---
10099 sample directives (commented out) for XBitHack, BindAddress,
10100 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10101 defaults, AddTypes for send-as-is and imagemap magic types, and
10102 improvements to samples for DirectoryIndex [Alexei Kosut]
10104 *) Yet more improvements to default config files --- changes to
10105 Alexei's sample AddLanguage directives, and sample LanguagePriority
10106 [ Florent Guillaume ]
10108 *) Set config file locations properly if not set in httpd.conf
10111 *) Don't escape URIs in internal redirects multiple times; don't
10112 do that when translating PATH_INFO to PATH_TRANSLATED either.
10115 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10117 Changes with Apache 0.8.3
10119 *) Edited distribution README to *briefly* summarize installation
10120 procedures, and give a pointer to the INSTALL file in the src/
10123 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10124 recent NCSA distributions.
10126 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10127 exist for the same directory, use both and don't segfault. [Reported
10130 *) Proper makefile dependencies [David Robinson]
10132 *) Note (re)starts in error log --- reported by Rob Hartill.
10134 *) Only call no2slash() after get_path_info() has been done, to
10135 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10136 reported by Andrew Wilson, though this one is probably a real bug]
10138 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10139 dump core when Referer is not supplied. [Randy Terbush]
10141 *) Lightly edited sample config files to refer people to our documentation
10142 instead of NCSA's, and to list Rob McCool as *original* author (also
10143 deleted his old, and no doubt non-functional email address). Would be
10144 nice to have examples of new features...
10146 Changes with Apache 0.8.2 19 Jul 1995
10148 *) Added AddLanuage code [Florent Guillaume]
10150 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10152 *) All sorts of problems when MultiViews finds a directory. It would
10153 be nice if mod_dir.c was robust enough to handle that, but for now,
10154 just punt. [reported by Brian Behlendorf]
10156 *) Wait for all children on restart, to make sure that the old socket
10157 is gone and we can reopen it. [reported by Randy Terbush]
10159 *) Imagemap module is enabled in default Configuration
10161 *) RefererLog and UserAgentLog modules properly default the logfile
10164 *) Mark Cox's mod_cookies added to the distribution as an optional
10165 module (commented out in the default Configuration, and noted as
10166 an experiment, along with mod_dld). [Mark Cox]
10168 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10170 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10172 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10174 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10177 Changes with Apache 0.8.1
10179 *) New imagemap module [Randy Terbush]
10181 *) Replacement referer log module with NCSA-compatible RefererIgnore
10182 [Matthew Gray again]
10184 *) Don't mung directory listings with very long filenames.
10185 [Florent Guillaume]
10187 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10189 *) New config script. See INSTALL for info. [Robert Thau]
10191 *) Scoreboard mechanism for regulating the number of extant server
10192 processes. MaxServers and StartServers defaults are the same as
10193 for NCSA, but the meanings are slightly different. (Actually,
10194 I should probably lower the MaxServers default to 10).
10196 Before asking for a new connection, each server process checks
10197 the number of other servers which are also waiting for a
10198 connection. If there are more than MaxServers, it quietly dies
10199 off. Conversely, every second, the root, or caretaker, process
10200 looks to see how many servers are waiting for a new connection;
10201 if there are fewer than StartServers, it starts a new one. This
10202 does not depend on the number of server processes already extant.
10203 The accounting is arranged through a "scoreboard" file, named
10204 /tmp/htstatus.*, on which each process has an independent file
10205 descriptor (they need to seek without interference).
10207 The end effect is that MaxServers is the maximum number of
10208 servers on an *inactive* server machine, but more will be forked
10209 off to handle unusually heavy loads (or unusually slow clients);
10210 these will die off when they are no longer needed --- without
10211 reverting to the overhead of full forking operation. There is a
10212 hard maximum of 150 server processes compiled in, largely to
10213 avoid forking out of control and dragging the machine down.
10214 (This is arguably too high).
10216 In my server endurance tests, this mechanism did not appear to
10217 impose any significant overhead, even after I forced it to put the
10218 scoreboard file on a normal filesystem (which might have more
10219 overhead than tmpfs). [Robert Thau]
10221 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10224 *) Read .htaccess files even in directory with <Directory> section.
10225 (Former incompatibility noted on mailing list, now fixed). [Robert
10228 *) "HEAD /" gives the client a "Bad Request" error message, rather
10229 than trying to send no body *and* no headers. [Cliff Skolnick].
10231 *) Don't produce double error reports for some very obscure cases
10232 mainly involving auth configuration (the "all modules decline to
10233 handle" case which is a sure sign of a server bug in most cases,
10234 but also happens when authentication is badly misconfigured).
10237 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10238 it's *for*, and this sort of thing really shouldn't be cluttering
10239 up the Makefile). [Robert Thau]
10241 *) Incidental code cleanups in http_main.c --- stop dragging
10242 sa_client around; just declare it where used. [Robert Thau]
10244 *) Another acc-related fix. (It doesn't like const char
10245 in some places...). [Mark Cox]
10247 Changes with Shambhala 0.6.1 13 Jul 1995
10249 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10250 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10252 *) Compiles clean with acc on SunOS [Paul Sutton]
10254 *) Reordered modules in modules.c so that Redirect takes priority
10255 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10256 believe it or not, he has an actual site with a ScriptAlias and
10257 a Redirect declared for the *exact same directory*. Even *my*
10258 compatibility fetish wouldn't motivate me to fix this if the fix
10259 required any effort, but it doesn't, so what the hey.
10261 *) Fixed to properly default several server_rec fields for virtual
10262 servers from the corresponding fields in the main server_rec.
10263 [Cliff Skolnick --- 'port' was a particular irritant].
10265 *) No longer kills off nph- child processes before they are
10266 finished sending output. [Matthew Gray]
10268 Changes with Shambhala 0.6.0 10 Jul 1995
10270 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10271 the connection to the client in an "aborted" state, but otherwise
10272 allow whatever handlers are running to clean up. hard_timeout()s
10273 abort the request in progress completely; anything not tied to some
10274 resource pool cleanup will leak. They're still around because I
10275 haven't yet come up with a more elegant way of handling
10276 timeouts when talking to something that isn't the client. The
10277 default_handler and the dir_handler now use soft timeouts, largely
10278 so I can test the feature. [Robert Thau]
10280 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10281 the case of log handlers dying prematurely is probably handled VERY
10282 gracelessly at this point, and if the logger stops reading input,
10283 the server will hang. (It is known to correctly restart the
10284 logging process on server restart; this is (should be!) going through
10285 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10286 script). [Robert Thau]
10288 *) asis files supported (new module). [Robert Thau]
10290 *) IdentityCheck code is compiled in, but has not been tested. (I
10291 don't know anyone who runs identd). [Robert Thau]
10293 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10294 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10296 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10298 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10299 as timeouts are not in scope. [Robert Thau]
10301 *) quoted-string args in config files now handled correctly (doesn't drop
10302 the last character). [Robert Thau; reported by Randy Terbush]
10304 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10305 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10307 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10308 default default type); the former default default behavior when all
10309 type-checkers defaulted had been a core dump. [Paul Sutton]
10311 *) Copy filenames out of the struct dirent when indexing
10312 directories. (On Linux, readdir() returns a pointer to the same
10313 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10315 Changes with Shambhala 0.5.3 [not released]
10317 *) Default response handler notes "file not found" in the error log,
10318 if the file was not found. [Cliff Skolnick].
10320 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10321 code no longer sets up bogus PATH_INFO which fakes out the directory
10322 handler). [Cliff Skolnick]
10324 Changes with Shambhala 0.5.2 06 Jul 1995
10326 *) Changes to http_main.c --- root server no longer plays silly
10327 games with SIGCHLD, and so now detects and replaces dying
10328 children. Child processes just die on SIGTERM, without taking
10329 the whole process group with them. Potential problem --- if any
10330 child process refuses to die, we hang in restart.
10331 MaxRequestsPerChild may still not work, but it certainly works
10332 better than it did before this! [Robert Thau]
10334 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10335 work (or work better, at least); over-long description lines
10336 properly terminated. [Mark Cox]
10338 *) http_request.c now calls unescape_url() more places where it
10339 should [Paul Sutton].
10341 *) More directory handling bugs (reported by Cox)
10342 Parent Directory link is now set correctly. [Robert Thau]
10344 Changes with Shambhala 0.5.1 04 Jul 1995
10346 *) Generalized cleanup interface in alloc.c --- any function can be
10347 registered with alloc.c as a cleanup for a resource pool;
10348 tracking of files and file descriptors has been reimplemented in
10349 terms of this interface, so I can give it some sort of a test.
10352 *) More changes in alloc.c --- new cleanup_for_exec() function,
10353 which tracks down and closes all file descriptors which have been
10354 registered with the alloc.c machinery before the server exec()s a
10355 child process for CGI or <!--#exec-->. CGI children now get
10356 started with exactly three file descriptors open. Hopefully,
10357 this cures the problem Rob H. was having with overly persistent
10358 CGI connections. [Robert Thau]
10360 *) Mutual exclusion around the accept() in child_main() --- this is
10361 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10362 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10363 This uses fcntl(F_SETLK,...) on the error log descriptor because
10364 flock() on that descriptor won't work on systems which have BSD
10365 flock() semantics, including (I think) Linux 1.3 and Solaris.
10367 This does work on SunOS (when the server is idle, only one
10368 process in the pool is waiting on accept()); it *ought* to work
10369 on the other systems. [Robert Thau]
10371 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10373 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10375 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10377 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10378 be unnecessary if I go to the revised timeout-handling scheme).
10381 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10382 string) even if none came in with the request. [Robert Thau]
10384 *) CHANGES file added to distribution ;-).
10386 Changes with Shambhala 0.4.5
10388 *) mod_dld --- early dynamic loading support [rst]
10389 *) Add wildcard content handlers for XBITHACK; default_hander now
10390 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10391 *) XBITHACK supported as a wildcard content-handler, and
10392 configurable at run-time (not just at compile time, as in the
10393 "patchy server" releases) [rst]
10395 Changes with Shambhala 0.4.4 30 Jun 1995
10397 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10398 *) Handle Addtype x/y .z [rst, reported by Cox]
10400 Changes with Shambhala 0.4.3
10402 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10403 synonymous [rst, terbush]
10405 Changes with Shambhala 0.4.1 28 Jun 1995
10407 *) First-cut virtual host implementation; some refit in the config
10408 reading code, and log management, was necessary to support this [rst]
10409 *) Sub-pool machinery, originally added to avoid excessive storage
10410 allocation on listings of large directories (which turned out to
10411 be the problem that the 0.3 storage accounting was added to
10412 find). Subrequests and mod_dir changed to use subpools. [rst]
10413 *) More memory debugging --- free list consistency checks. [rst]
10414 *) Added err_headers to request_rec, with support elsewhere [rst]
10415 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10417 Changes with Shambhala 0.3 19 Jun 1995
10419 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10420 *) Don't compile in mod_ai_backcompat by default
10421 *) Switch name of server from Apache to Shambhala in Makefile
10422 *) Add some accounting routines to track memory usage in the pools,
10425 Changes with Shambhala 0.2
10427 *) Set DOCUMENT_ROOT CGI variable
10428 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10429 *) Add critical section protection to handling of cleanup structures
10431 *) Significant code reorg within the server core to group related
10432 functions together [rst]
10433 *) Correctly handle clients that hang up before sending any request
10435 *) Replace dying child processes. [rst]
10437 Changes with Shambhala 0.1 12 Jun 1995
10439 Major rewrite of the pre-existing "patchy server" codebase, by
10440 Robert Thau (rst). Significant portions of the server code, such
10441 as configuration-file handling and HTTP authentication support,
10442 were ripped out and rewritten from scratch. Code that was not
10443 completely rewritten was significantly altered.
10445 Major changes with this release include:
10447 *) Introduction of the module API; in request handling, the central
10448 machinery just dispatches to various modules, which actually do
10449 most of the work. Configuration handling is similar --- modules
10450 declare their own commands, and the central machinery just
10451 dispatches to them.
10453 API features from shambhala/0.1 were substantially unchanged in
10454 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10455 release, such as wildcard handlers and subpools, were added in
10456 subsequent Shambhala releases, and were also generally rst's
10459 *) This release included the following modules:
10461 mod_access (access control --- allow and deny directives),
10462 mod_alias (Alias and Redirect commands),
10463 mod_auth (straight HTTP authentication, based on flat-files)
10464 mod_auth_dbm (same, with dbm files)
10465 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10466 mod_common_log (CLF access logs; later renamed mod_log_common)
10467 mod_dir (directory indexing)
10468 mod_include (server-side includes)
10469 mod_mime (AddType directives)
10470 mod_negotiation (content negotiation)
10471 mod_userdir (support for users' public_html directories)
10473 It also included a mod_ai_backcompat, which was a private hack
10474 for back-compatibility with rst's own AI-lab servers.
10476 All of these modules were substantially complete, and functional
10477 or nearly so (a few, which implemented features not in use at
10478 Thau's site, required patches of a few lines).
10480 *) sub-request machinery, to allow modules to determine how other
10481 modules would assign MIME types to a given file, or optionally
10482 serve its content (this is heavily used by mod_dir, mod_include
10483 and mod_negotiation).
10485 *) Resource pool system for keeping track of memory allocated and
10486 files opened in service of a particular request. Much of the
10487 code in the modules (when they weren't rewrites) was adjusted to
10488 replace a pervasive convention of using fixed-size buffers on
10489 the stack with an equally pervasive convention of using memory
10490 allocated with palloc().
10492 *) Reorganization of data structures associated with a given
10493 request to eliminate use of global variables and the troublesome
10494 unmunge_name function (used in NCSA and early Apache releases to
10495 attempt to determine the URI which mapped to a given filename
10496 --- a difficult proposition, given that it is easy to produce
10497 setups in which multiple URIs map to the same file).
10499 *) Source files renamed and rearranged
10501 *) Very simple pre-forking behavior --- parent process forked off a
10502 fixed number of children, and then just waited for SIGHUP.
10504 *) Other more minor changes too numerous to list.
10506 This release included modified versions of a lot of code from the
10507 Apache 0.6.4 public release, plus an early pre-forking patch
10508 codeveloped by Robert Thau and Rob Hartill.
10510 Changes with Apache 0.7.3 20 Jun 1995
10512 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10513 were incorporated by Rob Hartill on the main branch while Robert Thau
10514 worked on the Shambhala rewrite above. Most were merged into the
10515 Shambala architecture after Apache 0.8.0.
10517 Changes with Apache 0.6.4 13 May 1995
10519 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10522 Changes with Apache 0.5.1 10 Apr 1995
10524 Changes with Apache 0.4 02 Apr 1995
10526 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10529 Changes with Apache 0.3 24 Mar 1995
10531 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10534 Changes with Apache 0.2 18 Mar 1995
10536 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10537 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10538 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
