1 Changes with Apache 2.0.29-dev
3 *) Add mod_deflate to experimental.
4 [Ian Holsman, Justin Erenkrantz]
6 *) Bail out at configure time if an invalid MPM was specified.
7 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
9 *) Prevent segv in ap_note_basic_auth_failure() when no AuthName is
10 configured [John Sterling <sterling@covalent.net>]
12 *) Fix apxs to use sbindir. [Henri Gomez <hgomez@slib.fr>]
14 *) Fix a problem with IPv6 vhosts. PR #8118 [Jeff Trawick]
16 *) Optimization for the BNDM string-search function in
17 mod_include. [Brian Pane]
19 *) Fixed the behavior of the XBitHack directive.
20 [Taketo Kabe <kabe@sra-tohoku.co.jp>, Cliff Woolley] PR#8804
22 *) The threaded MPM for Unix has been removed. Use the worker
23 MPM instead. [various]
25 *) APR-ize the resolver logic in mod_unique_id. This fixes a bug
26 in logging the error from a failed DNS lookup. [Jeff Trawick]
28 *) Added the missing macros AP_INIT_TAKE13 and AP_INIT_TAKE123.
31 *) Get mod_cgid killed when a MPM exits due to a fatal error.
34 *) Fix a file descriptor leak in mod_include. When we include a
35 file, we use a sub-request, but we didn't destroy the sub-request
36 immediately, instead we waited until the original request was
37 done. This patch closes the sub-request as soon as the data is
38 done being generated. [Brian Pane <bpane@pacbell.net>]
40 *) Allow modules that add sockets to the ap_listeners list to
41 define the function that should be used to accept on that
42 socket. Each MPM can define their own function to use for
43 the accept function with the MPM_ACCEPT_FUNC macro. This
44 also abstracts out all of the Unix accept error handling
45 logic, which has become out of synch across Unix MPMs.
48 *) Fix a bug which would cause the response headers to be omitted
49 when sending a negotiated ErrorDocument because the required
50 filters were attached to the wrong request_rec.
51 [John Sterling <sterling@covalent.net>]
53 *) Remove commas from the end of the macros that define
54 directives that are used by MPMs. Prior to this patch,
55 you would use these macros without commas, which was unlike
56 the macros for any other directives. Now, the caller provides
57 the comma rather than the macro providing it. This makes
58 the macros look more like the rest of the directives.
59 [Ryan Bloom and Cliff Woolley]
61 *) Add 'redirect-carefully' environment option to disable sending
62 redirects under special circumstances. This is helpful for
63 Microsoft's WebFolders when accessing a directory resource via
64 DAV methods. [Justin Erenkrantz]
66 *) Begin to abstract out the underlying transport layer.
67 The first step is to remove the socket from the conn_rec,
68 the server now lives in a context that is passed to the
69 core's input and output filters. This forces us to be very
70 careful when adding calls that use the socket directly,
71 because the socket isn't available in most locations.
74 *) Really reset the MaxClients value in worker and threaded
75 when the configured value is not a multiple of the number
76 of threads per child. We said we did previously but we
77 forgot to. [Jeff Trawick]
79 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
81 *) If shared modules are requested and mod_so is not available,
82 produce a fatal config-time error. [Justin Erenkrantz]
84 *) Improve http2env's performance by cutting the work it has to
85 do. [Brian Pane <bpane@pacbell.net>]
87 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
88 [Brian Pane <bpane@pacbell.net>]
90 Changes with Apache 2.0.28
92 *) Fix infinite loop in mod_cgid.c.
93 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
95 *) When no port is given in a "ServerName host" directive, the
96 server_rec->port is now set to zero, not 80. That allows for
97 run-time deduction of the correct server port (depending on
98 SSL/plain, and depending also on the current setting of
99 UseCanonicalName). This change makes redirections
100 work, even with https:// connections. As in Apache-1.3, the
101 connection's actual port number is never used, only the ServerName
102 setting or the client's Host: setting. Documentation updated
103 to reflect the change. [Martin Kraemer]
105 *) Add a '%{note-name}e' argument to mod-headers, which works in
106 the same way as mod_log_confg. [Ian Holsman]
108 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
109 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
110 MPMs. [Cliff Woolley]
112 *) Introduce htdbm, a user management utility for db/dbm authorization
113 databases. [Mladen Turk <mturk@mappingsoft.com>]
115 *) Optimize usage of strlen and strcat in ap_directory_walk.
116 [Brian Pane <bpane@pacbell.net>]
118 Changes with Apache 2.0.27
120 *) Introduce an Apache mod_ssl initial configuration template
121 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
123 *) Fixed a memory leak in the getline parsing code that could
124 be triggered by arbitrarily large header lines. Requests
125 from the core input filter for single lines are now limited
126 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
128 *) Fix a truncation bug in how we print the port on the Via: header.
129 The routine that prints the Via: header now takes a length for
130 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
132 *) Some syntax errors in mod_mime_magic's magic file can result
133 in a 500 error, which previously was unlogged. Now we log the
134 error. [Jeff Trawick]
136 *) Add the support/checkgid helper app, which checks the run-time
137 validity of group identifiers usable in the Group directive.
140 *) Various --enable-so options have been fixed: --enable-so is
141 treated as "static"; explicit --enable-so=shared issues an error;
142 and explicit --enable-so fails with error on systems without
143 APR_HAS_DSO. [Aaron Bannert]
145 *) Fix a segfault in the core input filter when the client socket
146 gets disconnected unexpectedly. [Cliff Woolley]
148 *) Fix the reporting for child processes that die. This removes
149 all of the non-portable W* macros from Apache.
150 [Jeff Trawick and Ryan Bloom]
152 *) Win32: Track and display "Parent Server Generation:" in
153 mod_status output. The generation will be bumped at
154 server graceful restart, when the child process exits
155 by hitting MaxRequestsPerChild or if the child
156 process exits abnormally. [Bill Stoddard]
158 *) Win32: Fix problem where MaxRequestsPerChild directive was
159 not being picked up in favor of the default. Enable
160 the parent to start up a new child process immediately upon
161 the old child starting shutdown.
164 *) Fix some bungling of the remote port in rfc1413.c so that
165 IdentityCheck retrieves the proper user id instead of failing
166 and thus always returning "nobody."
167 [Dick Streefland <Dick.Streefland@xs4all.nl>]
169 *) Introduced thread saftey for mod_rewrite's internal cache.
170 [Brian Pane <bpane@pacbell.net>]
172 *) Simplified mod_env's directives to behave as most directives are
173 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
174 directive following that UnsetEnv within the same container.
175 Also provides a runtime startup warning if a PassEnv configured
176 environment value is undefined. [William Rowe]
178 *) The worker MPM is now completely ported to APR's new lock API. It
179 uses native APR types for thread mutexes, cross-process mutexes,
180 and condition variables. [Aaron Bannert]
182 *) Sync up documentation to remove all references to the now deprecated
183 Port directive. [Justin Erenkrantz]
185 *) Moved all ldap modules from the core to httpd-ldap sub-project
188 *) Exit when we can't listen on any of the configured ports. This
189 is the same behavior as 1.3, and it avoids having the MPMs to
190 deal with bogus ap_listen_rec structures. [Jeff Trawick]
192 *) Cleanup the proxy code that creates a request to the origin
193 server. This change adds an optional hook, which allows modules
194 to gain control while the request is created if the proxy module
195 is loaded. The purpose of this hook is to allow modules to add
196 input and/or output filters to the request to the origin. While
197 I was at it, I made the core use this hook, so that proxy request
198 creation uses some of the code from the core. This can still be
199 greatly improved, but this is a good start. [Ryan Bloom]
201 Changes with Apache 2.0.26
203 *) Port the MaxClients changes from the worker MPM to the threaded
206 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
207 with the new input filtering system. [Justin Erenkrantz]
209 *) Introduce the MultiviewsMatch directive, to allow the operator
210 to be flexible in recognizing Handlers and Filters filename
211 extensions as part of the Multiviews matching logic, strict with
212 MultiviewsMatch NegotiatedOnly to accept only filename extentions
213 that designate negotiated parameters, (content type, charset, etc.)
214 or MultiviewsAll for the 1.3 behavior of matching any files, even
215 if they have unregistered extensions. [William Rowe]
217 *) Fixed the configure script to add a LoadModule directive to
218 the default httpd.conf for any module that was compiled
219 as a DSO. [Aaron Bannert <aaron@clove.org>]
221 *) rewrite mod_ssl input filtering to work with the new input filtering
222 system. [Justin Erenkrantz]
224 *) prefork: Don't segfault when we are able to listen on some but
225 not all of the configured ports. [Jeff Trawick]
227 *) Build mod_so even if no core modules are built shared.
228 [Aaron Bannert <aaron@clove.org>]
230 *) Introduce ap_directory_walk rewrite (with further optimizations
231 required) to adapt to the ap_process_request_internal() changes.
232 Optimized so subrequests and redirects now reuse previous section
233 merges, until we mismatch with the original directory_walk, and
234 precomputed r->finfo results will cause directory_walk to skip
235 the most expensive phases of the function. [William Rowe]
237 *) Allow ApacheMonitor to connect to and control Apache on other
238 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
240 *) Remove the Port directive. In it's place, the Listen directive
241 is now a required directive, which tells Apache what port to
242 listen on. The ServerName directive has also been extended
243 to accept an optional port. If the port is specified to the
244 ServerName, the server will report that port whenever it
245 reports the port that it is listening on. This change was
246 made to ease configuration errors that stem from having a Port
247 directive, and a Listen directive. In that situation, the server
248 would only listen to the port specified by the Listen command,
249 which caused a lot of confusion to users. [Ryan Bloom]
251 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
252 build, as loadable modules. [William Rowe]
254 *) Fix --enable-mods-shared processing. If most is specified,
255 then all modules that can be compiled as shared modules are.
256 [Aaron Bannert <aaron@clove.org>]
258 *) Update the mime.types file to map video/vnd.mpegurl to mxu
259 and add commonly used audio/x-mpegurl for m3u extensions.
260 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
262 *) Eliminate the depreciated r->content_language, in favor of the array
263 r->content_languages introduced many years ago. Module authors must
264 substantially overhaul their modules, so this needs to be upgraded
265 if the module still relied on backwards-brokeness. [William Rowe]
267 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
270 *) Rewrite the input filtering mechanisms to consolidate and reorganize
271 code. In short, core_input_filter does something now and
272 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
274 *) Update the Win32 build to re-absorb mod_proxy and family.
277 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
278 current SDK.) [William Rowe]
280 *) Some style changes to the code that does ProxyErrorOverride. Fixed
281 config merge behaviour. [Graham Leggett]
283 *) Allow support programs to be compiled against a static version
284 of libapr. This allows the smaller support programs to be
285 relocated. [Aaron Bannert <aaron@clove.org>]
287 *) Update the mime.types file to the registered media types as
288 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
290 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
291 number of clients that can connect at the same time, instead of
292 specifying the maximum number of child processes.
293 [Aaron Bannert <aaron@clove.org>]
295 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
296 be consistent with 1.3. [Justin Erenkrantz]
298 *) Cache apr_explode_localtime() value for 15 seconds.
299 [Brian Pane <bpane@pacbell.net>]
301 *) Fix mod_include to not return ETag or Last-Modified headers.
302 [Ian Holsman <ianh@cnet.com>]
304 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
306 *) Eliminate the wasteful run-time conversion of method names from strings
307 to numbers in places where the methods are known at compile time.
308 [Brian Pane <bpane@pacbell.net>]
310 *) Turn the worker MPM's queue into a LIFO. This may
311 improve cache-hit performance under some conditions.
312 [Aaron Bannert <aaron@clove.org>]
314 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
315 support it. [Justin Erenkrantz]
317 *) Cleanup the worker MPM. We no longer re-use transaction
318 pools. This incurs less overhead than shuffling the pools
319 around so that they can be re-used. Remove one of the
320 queue's condition variables. We just redefined the API to
321 state that you can't try to add more stuff than you allocated
322 segments for. [Aaron Bannert <aaron@clove.org>]
324 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
326 *) Fixed persistent connections when a request contains a body.
329 *) mod_dav uses a new API to speak to the backend provider for dead
330 property management. [Greg Stein]
332 *) Remove the Win32 script-processing exception from mod_cgi, and
333 roll build_command_line/build_argv_list into a unified, overrideable
334 ap_cgi_build_command optional function. [William Rowe]
336 *) Rewrite find_start_sequence to use a better search algorithm
337 to find the start tag. [Justin Erenkrantz]
339 *) Fix a seg fault in mod_include. When we are generating an
340 internal redirect, we must set r->uri to "", not a bogus
341 string, and not NULL. [Ryan Bloom]
343 *) Optimized location_walk, so subrequests, redirects and second passes
344 now reuse previous section merges on a <Location > by <Location >
345 basis, until we mismatch with the original location_walk.
348 *) Back out the 1.45 change to util_script.c. This change made
349 us set the environment variable REQUEST_URI to the redirected
350 URI, instead of the originally requested URI.
351 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
353 *) Make mod_include do lazy evaluation of potentially expensive to
354 compute variables. [Brian Pane <bpane@pacbell.net>]
356 *) Fix logging of bytes sent for HEAD requests. %b and %B should
357 log either - or 0, before this patch, they were both logging
358 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
360 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
361 than per character. [Brian Pane <bpane@pacbell.net>]
363 *) Normalize the primary request, redirects and sub-requests to
364 run the same ap_process_request_internal for consistency in
365 robustness, behavior and security. [William Rowe]
367 *) Fix a segfault with mod_include when r->path_info is not set
368 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
370 *) Add -X functionality back. This indicates to all MPMs and any other
371 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
373 *) Some initial support for the cygwin platform [prefork only].
374 This is not to be confused with support for the WinNT/Win32
375 platform, which is the recommended configuration for native
376 Win32 users. The cygwin platform support is recommended for
377 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
379 *) Changed syntax of Set{Input|Output}Filter. The list of filters
380 must be semicolon delimited (if more than one filter is given.)
381 The Set{Input|Output}Filter directive now overrides a parent
382 container's directive (e.g. SetInputFilter in <Directory /web/foo>
383 will override any SetInputFilter directive in <Directory /web>.)
384 This new syntax is more consistent with Add{Input|Output}Filter
385 directives defined in mod_mime. Also cures a bug in prior releases
386 where the Set{Input|Output}Filter directive would corrupt the
387 global configuration if the multiple directives were nested.
390 *) Cured what's ailed mime for quite some time. If an AddSomething
391 was given in the configuration (Language, Charset, Handler or
392 Encoding) Apache would set the content type as given by AddType,
393 but refused to check the mime.types file if AddType wasn't given
394 for that specific extension. Setting the AddHandler for .html
395 without setting the AddType text/html html would cause Apache to
396 use the default content type. [William Rowe]
398 *) Added some bulletproofing to memory allocation in the LDAP cache
399 code. [Graham Leggett]
401 Changes with Apache 2.0.25
403 *) Move the installed /manual directory out of the /htdocs/ tree, so
404 that it can be kept more independently from the remaining document
405 root. The "Alias /manual ..." already allowed for easy projection
406 into existing private document trees. [Martin Kraemer]
408 *) Add specified user attributes to the environment when using
409 mod_auth_ldap. This allows you to use mod_include to embed specified
410 user attributes in a page like so:
411 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
414 *) Fix a performance problem with the worker MPM. We now create
415 transaction pools once, and re-use them for each connection.
416 [Aaron Bannert <aaron@clove.org>]
418 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
419 of a 'handler' or 'filter', so that any filename extension that does
420 not contribute to the negotiated metadata can't be served without
421 an explicit request. E.g., if the .Z extension is associated with
422 an unzip filter, the user request somefile.Z.html, mod_negotiation
423 won't serve it. It can serve somefile.Z.html when somefile.Z is
424 requested, since the .Z extension is explictly requested, if the
425 .html extension is associated with ContentType text/html.
428 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
429 and corresponding AddOutputFilter syntax, to insert one or more
430 filters by mod_mime filename extension processing.
433 *) Fix a growing connection pool in core_output_filter() for
434 keepalive requests. [Jeff Trawick]
436 *) Moved split_and_pass_pretag_buckets back to being a
437 macro at Ryans's request. Removed the return from it
438 by setting and returning a return code instead. Updated
439 the code to check the return code from the macro and
440 do the right thing. [Paul J. Reder]
442 *) Fix a segfault when a numeric value was received for Host:.
445 *) Add a function ap_remove_input_filter. This is to match
446 up with ap_remove_output_filter. [Ryan Bloom]
448 *) Clean up location_walk, so that this step performs a minimum
449 amount of redundant effort (it must be run twice, but it will no
450 longer reparse all <Location > blocks when the request uri
451 hadn't changed.) [William Rowe]
453 *) Eliminate proxy: (and all other 'special') processing from the
454 ap_directory_walk() phase. Modules that want to use special
455 walk logic should refer to the mod_proxy map_to_location example,
456 with it's proxy_walk and proxysection implementation. This makes
457 either directory_walk flavor much more legible, since that phase
458 only runs against real <Directory > blocks.
461 *) Fix a security problem in mod_include which would allow
462 an SSI document to be passed to the client unparsed.
463 [Cliff Woolley, Brian Pane]
465 *) Introduce the map_to_storage hook, which allows modules to bypass
466 the directory_walk and file_walk for non-file requests. TRACE
467 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
468 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
471 *) Add the ability for mod_include to add the INCLUDES filter
472 if the file is configured for the server-parsed handler.
473 This makes the configuration for .shtml files much easier
474 to understand, and allows mod_include to honor Apache 1.3
475 config files. Based on Doug MacEachern's patch to PHP
476 to do the same thing. [Ryan Bloom]
478 *) force OpenSSL to ignore process local-caching and to always
479 get/set/delete sessions using mod_ssl's callbacks
480 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
481 Geoff Thorpe <geoff@geoffthorpe.net>]
483 *) Make the worker MPM shutdown and restart cleanly. This also
484 cleans up some race conditions, and gets the worker using
485 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
487 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
489 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
491 *) Fix for mod_include. Ryan's patch to check error
492 codes put a return in the wrong place. Also, the
493 include handler return code wasn't being checked.
494 I don't like macros with returns, so I converted
495 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
496 [Paul J. Reder <rederpj@raleigh.ibm.com>]
498 *) fix segv in mod_mime if no AddTypes are configured
499 [John Sterling <sterling@covalent.net>]
501 *) Enable ssl client authentication at SSL_accept time
502 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
504 *) Fix a segfault in mod_include when the original request has no
505 associated filename (e.g., we're filtering the error document for
506 a bad URI). [Jeff Trawick]
508 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
510 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
511 of httpd is started and shuts down due to socket conflict. Moving the
512 call to ap_log_pid solves the problem.
514 *) Changed the late-1.3 log_config substitution %c to %X, to log the
515 status of the closed connection, as it conflicts with the far more
516 common, historical ssl logging directive %...{var}c. [William Rowe]
518 *) Added the common error/ tree to the build/install targets
519 (similar to the common icons/ tree) for the multi-language error
520 messages that Lars committed earlier. [William Rowe]
522 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
524 *) Added a default commented-out mod_ldap and mod_auth_ldap
525 configuration to httpd-std.conf and httpd-win.conf
528 *) Added documentation for mod_ldap and mod_auth_ldap.
531 *) Enabled negative caching on attribute comparisons in the LDAP cache.
532 Fixed a problem where the default cache TTL was set in milliseconds
533 not microseconds causing the cache to time out almost immediately.
536 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
537 module code to follow APR. [Graham Leggett]
539 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
540 cleaned up when the connection pool pool is cleaned up.
543 *) Fix a minor issue with Jeff Trawick's mod_include
544 patch. Without this patch, the code will just allocate
545 more bytes in get_combined_directive than are needed.
548 *) Added the LDAP authentication module mod_auth_ldap.
549 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
551 *) Added the LDAP cache and connection pooling module mod_ldap.
552 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
554 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
555 by allowing a module to disable itself if its prerequisites are not
556 met. [Justin Erenkrantz]
558 Changes with Apache 2.0.24
560 *) Fix a couple of issues in mod_include when the tag appeared at
561 offsets near 8192 in the file being parsed. [Jeff Trawick]
563 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
564 reached. [Jeff Trawick]
566 *) Numerous improvements to the Win32 build system. Introduced command line
567 builds without requiring .mak files for MSVC 6.0 and later versions.
568 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
571 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
572 reporting of uninstalled services and other error conditions, and changed the
573 default service name to Apache2. [William Rowe]
575 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
576 compatibility with existing Apache 1.3 Win32 Apache management utilites.
577 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
579 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
580 [William Rowe, Greg Ames]
582 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
583 and RemoveCharset directives. [William Rowe]
585 *) The Unix MPMs other than perchild now allow child server
586 processes to use the accept mutex when starting as root and
587 using SysV sems for the accept mutex. Previously, this
588 combination would lead to fatal errors in the child server
589 processes. perchild can't use SysV sems because of security
590 issues. [Jeff Trawick, Greg Ames]
592 *) Added Win32 revision stamp resources to all http binaries
593 (including modules/ and support/ tools.) PR7322 [William Rowe]
595 *) Fix ap_rvprintf to support more than 4K of data at one time.
596 [Cody Sherr <csherr@covalent.net>]
598 *) We have always used the obsolete/deprecated Netscape syntax
599 for our tracking cookies; now the CookieStyle directive
600 allows the Webmaster to choose the Netscape, RFC2109, or
601 RFC2965 format. The new CookieDomain directive allows the
602 setting of the cookie's Domain= attribute, too. PR #s 5006,
603 5023, 5920, 6140 [Ken Coar]
605 *) Tweak server/Makefile so that the rules for generating exports.c
606 are compatible with make utilities which don't expand wildcards
607 in a dependency list (e.g., OS/390 make, certain levels of GNU
608 make). [Jeff Trawick]
610 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
612 *) Begin to sanitize the MPM configuration directives. Now, all
613 MPMs use the same functions for all common MPM directives. This
614 should make it easier to catch all bugs in these directives once.
615 [Cody Sherr <csherr@covalent.net>]
617 *) Close a major resource leak. Every time we had issued a
618 graceful restart, we leaked a socket descriptor.
621 *) Fix a problem with the new method code. We need to cast
622 the 1 to an apr_int64_t or it will be treated as a 32-bit
623 integer, and it will wrap after being shifted 32 times.
624 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
626 *) Fix a bug in mod_expires. Previous to this patch, if you
627 told mod_expires to add 604800 seconds to the last-modified
628 time, it actually added 604800 usec's to the last-modified time,
629 so that when looking at the response it looked like nothing
630 had been done. The root of the problem was that we always compute
631 time in usec's, but we ask users to input sec's. This means we
632 need to convert to usec's before using those values.
635 *) The worker MPM now handles shutdown and restart requests. It
636 definitely isn't perfect, but we do stop the servers correctly.
637 The biggest problem right now is that SIGHUP causes the server to
638 just die. [Ryan Bloom]
640 Changes with Apache 2.0.23
642 *) Use the prefork MPM by default on Unix. [various]
644 *) Added a systray icon monitor application for Win32.
645 [Mladen Turk <mturk@mappingsoft.com>]
647 *) mod_rewrite: Fix the line ending on some non-Unix systems for
648 messages written to the rewrite log.
649 [Richard Labennett <rlabenn@us.ibm.com>]
651 *) All mod_autoindex query parsing is now quietly quashed with the
652 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
653 still drops the column sort <a href>'s for the column headers, but
654 IgnoreClient is required to ignore these Query options entirely.
657 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
658 to allow the client to select plain, FancyIndexing or HTMLTable
659 formatting, V=[0|1] to inhibit or enable version sorting, and
660 P=pattern to return only specific files. The old Query Arguments
661 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
662 as before), and O=A|D for ordering ascending or descending.
665 *) Fixed an error in mod_include's directive parsing routines which
666 caused #if, #elif, and #else expressions containing backslashes
667 to be improperly evaluated. [Cliff Woolley]
669 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
670 drop the icon column, SuppressRules to drop the <hr> elements,
671 and HTMLTable to create rudimentary HTML table listings (implies
672 FancyIndexing). [William Rowe]
674 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
675 from Apache 1.3.15. This is needed for two reasons, first, given
676 multiple machines within a server farm, ETags and Last-Modified
677 stamps won't correspond from machine to machine, and second, many
678 Unixes don't capture changes to the date or time stamp of existing
679 files, since these don't modify the dirent itself. [William Rowe]
681 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
682 and DirectoryWidth options from Apache 1.3.10.
683 [William Rowe, Ken Coar]
685 *) Eliminated FancyIndexing directive, deprecated early in Apache
686 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
688 *) mod_autoindex now excludes any file names that would result in
689 an error, other than a success or redirect. Also optimized
690 the parent directory, always included except in the URI '/'.
693 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
694 negotiated index pages, and prevent the server from defaulting
695 to an autoindex of the directory. mod_negotiation will now die
696 with a 500 Internal Error if it could match some filenames
697 (e.g. for mod_dir) but none can be served. mod_negotation now
698 refuses to serve any file with an extention that mod_mime doesn't
699 recognize, and wasn't part of the request. [William Rowe]
701 *) Eliminate mod_cgi's handling of .exe files without the .exe file
702 extension. This is already handled by multiviews, if the admin
703 wishes to AddHandler .exe or define a content type handler and
704 associate .exe files with that content type. Multiviews must be
705 enabled to allow these to be served. [William Rowe]
707 *) Speed up the server's response to a spike in incoming workload
708 or restarts by assigning empty scoreboard slots to new processes
709 when they are available. [Greg Ames]
711 *) Add a handler to mod_includes.c. This handler is designed to
712 implement the XbitHack directive. This can't be done with a
713 fixup, because we need to check the content-type, which is
714 only available in the handler phase. [Ryan Bloom]
716 *) Make the includes filter check return codes from filters lower in
717 the filter chain. If a lower level filter returns an error, then
718 the request needs to stop immediately. This allows mod_include to
719 stop parsing data once a lower filter recognizes an error.
722 *) Add the ability to extend the methods that Apache understands
723 and have those methods <limit>able in the httpd.conf. It uses
724 the same bit mask/shifted offset as the original HTTP methods
725 such as M_GET or M_POST, but expands the total bits from an int to
726 an ap_int64_t to handle more bits for new request methods than
727 an int provides. [Cody Sherr <csherr@covalent.net>]
729 *) Fix broken mod_mime behavior in merging its arguments. Possible
730 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
732 *) Solve many mod_ssl porting issues (too many to detail) with
733 help from the whole team, but most notably [Ralf S. Engelschall,
734 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
735 Doug MacEachern, William Rowe, Cliff Woolley]
737 *) More stall fixes for the threaded & worker mpm's.
738 Make mod_status output more accurate. Don't
739 count workers in processes which aren't actively
740 serving requests. [Greg Ames]
742 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
744 *) Add a single listener/multiple worker MPM. This MPM is
745 definately not fully correct, but it allows us to solve many
746 of the problems that exist in the threaded MPM. This is a
747 modified version of the threaded MPM. [Ryan Bloom]
749 *) Improve content generation throughout Apache, providing closer
750 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
751 Transitional specifications. [William Rowe]
753 Changes with Apache 2.0.22
755 *) Fix a problem where the threaded MPM stalls after restarts or
756 segfaults. Also prevent multiple active processes from using
757 the same scoreboard slot. [Greg Ames]
759 *) Apache/Win32 now fills in the service description with Apache's
760 server version string, including loaded and advertised modules.
763 *) Improved support for the Win32 build, to recover gracefully from
764 missing apr or apr-util directories or the awk interpreter,
765 create the proper cgi-bin examples, including a test-cgi.bat, and
766 fix the perl shebang line for printenv.pl, when installing from
767 the build environment. [William Rowe]
769 *) Fix a segfault in threaded.c caused by passing uninitialized
770 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
772 *) Use new APR number conversion functions to reduce CPU consumption
773 when setting the content length, and in mod_log_config.
776 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
777 where HEAD response headers were being repeated twice for
778 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
779 problem in the http_header filter was exposed by the recent rewrite
780 of the content_length filter. [Taketo Kabe, Bill Stoddard]
782 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
783 restarts. A garbage pointer to a vhost's server_rec from the
784 previous generation was being left around under certain
785 conditions. [Greg Ames]
787 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
788 used to appear as '(none', without the closing paren.
789 [Günter Knauf <eflash@gmx.net>]
791 *) Improve the exports generating awk script. In the past, we had
792 work around problems in the awk script by avoiding some #if and
793 #ifdefs. This has bitten us many times in generating the exports.c
794 file. This improvement allows corrects the header file parsing.
795 [Sander Striker <striker@apache.org>]
797 Changes with Apache 2.0.21
799 *) Resolve the Win32 htpasswd bug, where a file that existed would be
800 overwritten, regardless of the -c flag.
801 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
803 *) Introduce connection sub-pools into ab. Truncating the lifetime
804 of these allocations means that ab no longer perpetually grows
805 its working set, running out of memory on large request attempts.
808 *) Make scoreboard creation a hook. This allows management
809 modules to have access to the scoreboard at the time that it is
810 created, and at every restart request.
811 [Cody Sherr <csherr@covalent.net>]
813 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
814 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
815 daemon index actually used in the scoreboard. I also
816 updated the pertinent calls. [Paul J. Reder]
818 *) Win32: Prevent listening sockets from being inherited by
819 the Apache child process, CGI scripts, rotatelog process
820 etc. If the Apache child process segfaults, any processes
821 that the child started are not reaped. Prior to this fix,
822 these processes inherited the listening sockets which sometimes
823 prevented the restarted Apache child process from accepting
824 connections (ie, the server would hang).
827 *) Provide vhost and request strings when ExtendedStatus is on.
830 *) Fix some issues with the pod and prefork: check the pod *after*
831 processing a connection so that a server processing a time-
832 consuming request bails out as soon as practical; when the
833 parent process wakes up a server process via connect(), use an
834 APR timeout on the connect() so that we don't hang for a long
835 time if there aren't server processes around to do accept().
836 [Jeff Trawick, Greg Ames]
838 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
839 spends a lot of time in apr_table_get calls. Using the default
840 httpd.conf, the tables for languages and charsets are somewhat
841 large, so the time spent scanning them on each request is
842 significant. Replacing the tables with hash tables provides
843 a nice speedup. [Brian Pane <bpane@pacbell.net>]
845 *) Add two functions to allow modules to access random parts of the
846 scoreboard. This allows modules compiled for one MPM to access the
847 scoreboard, even if it the server was compiled for another MPM.
848 [Harrie Hazewinkel <harrie@covalent.net>]
850 Changes with Apache 2.0.20
852 *) Fix problem in content-length filter where the filter would
853 buffer all the output from a CGI before sending any bytes
854 down the filter stack to the network. This problem would cause
855 significant memory consumption if the CGIs generated
856 lots of bytes. [Bill Stoddard]
858 *) Get non-blocking CGI pipe reads working with the bucket brigades.
861 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
864 *) Fix a bug in the threaded MPM that would cause it to kill off all
865 workers immediately after starting if the number of workers started
866 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
868 Changes with Apache 2.0.19
870 *) Fix problem with threaded MPM. The problem was that if each child
871 process was busy serving a single long-lived request and the server
872 was sent a graceful restart signal, the server would stop serving
873 requests. This would happen because each child process would wait to
874 die until the last thread was done, and the parent wouldn't spawn any
875 new children until a process died. Now, the parent looks at the fact
876 that the children are dying gracefully, and starts new children.
877 Those new children only start enough threads to compliment the number
878 of threads in the other child process that shares the same spot in
879 the scoreboard. In this way, we make sure to never go over
880 MaxClients. [Ryan Bloom]
882 *) modified mod_negotiation and mod_autoindex to speed up by almost a
883 factor of two on apr_dir_read()-enhanced platforms, such as Win32
884 and OS2, by calling ap_sub_request_lookup_dirent() with the results
885 already provided by apr_dir_read(). [William Rowe]
887 *) mod_file_cache is now more robust to filtering and serves requests
888 slightly more efficiently. [Cliff Woolley]
890 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
891 Module was calling ap_rwrite() followed by ap_rflush() but the
892 served content was not being displayed in the browser. Inspection
893 of the output stream revealed that the first data chunk was
894 missing the trailing CRLF required by the RFC. [Bill Stoddard]
896 *) apxs no longer generates ap_send_http_header() in the example handler
898 *) Fix an ab problem which could cause a divide-by-zero exception
899 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
900 [Ian Holsman <ianh@cnet.com>]
902 *) Solve case-insensitive platforms' confusion about negotiated
903 filenames, allowing files of differnt case to match in choosing
904 the document to serve. [William Rowe]
906 *) Fix brokenness when ThreadsPerChild is higher than the built-in
907 limit. We left ap_threads_per_child at the higher value which
908 led to segfaults when doing certain scoreboard operations.
911 *) Fix seg faults and/or missing output from mod_include. The
912 default_handler was using the subrequest pool for files and
913 MMAPs, even though the associated APR structures typically
914 live longer than the subrequest. [Greg Ames]
916 *) Extend mod_setenvif to support specifying regular expressions
917 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
918 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
919 will cause HAVE_TS to be set if any of the request headers begins
920 with "TS" and has a value that begins with any character in the
921 set [a-z]. [Bill Stoddard]
923 *) httpd children now re-bind themselves to a random CPU on
924 multiprocessor systems on AIX via bindprocessor() in 2.0.
925 [Victor J. Orlikowski]
927 *) Fix htdigest. It would go into a loop in getline when adding
928 a second user. [Bill Stoddard]
930 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
932 *) Automatically generate httpd.exp for AIX.
933 DSOs now work again on AIX in 2.0
934 [Victor J. Orlikowski]
936 *) Add a new request hook, error_log. This phase allows modules
937 to act on the error log string _after_ it has been written
938 to the error log. The goal for this hook is to allow monitoring
939 modules to send the error string to the monitoring agent.
942 *) Modify mod_echo to make it use filters for input and output.
943 [Ryan Morgan <rmorgan@covalent.net>]
945 *) Extend mod_headers to support conditional driven Header
946 add, append and set. Use SetEnvIf to set an envar and conditionally
947 add/append/set headers based on this envar thusly:
949 SetEnvIf TSMyHeader value HAVE_TSMyHeader
950 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
952 If the request contains header "TSMyHeader: value" then header
953 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
956 *) Extend mod_headers to support using format specifiers on Header
957 add, append and set header values. Two format specifiers are supported:
959 %t - reports, in UTC microseconds since the epoch, when the
960 request was received.
962 %D - reports the time, in microseconds, between when the request was
963 received and the response sent.
966 Header add MyHeader "This request served in %D microseconds. %t"
968 results in a header being added to the response that looks like this:
970 MyHeader: This request served in D=5438 microseconds. t=991424704447256
974 *) Fix reset_filter(). We need to be careful how we remove filters.
975 If we set r->output_filters to NULL, we also have to reset the
976 connection's filters. [John Sterling]
978 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
980 *) Add a check to ap_die() to make sure the filter stack is sane and
981 contains the correct basic filters when an error occurs. This fixes
982 a problem where headers are not being sent on error. [John Sterling]
984 *) New Header directive 'echo' option. "Header echo regex" will
985 cause any headers received on the request that match regex to be
986 echoed to (included in) the response headers.
989 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
990 This prevented the inclusion of apr_compat.h. PR #7773
991 [Oleg Broytmann <phd@phd.pp.ru>]
993 *) Moved util_uri to the apr-util library. This required a bunch of
994 apr_name changes for the uri utility functions. [Justin Erenkrantz]
996 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
997 insert_filter phase so that other filters are not bypassed by default.
1000 *) Reimplement mod_headers as an output filter. mod_headers can now
1001 add custom headers to inbound requests using the RequestHeader directive
1002 and to responses using the same old Header directive. [Graham Leggett]
1004 Changes with Apache 2.0.18
1006 *) Fix command-line processing so that if a bad argument is specified
1007 Apache will exit. [Jeff Trawick]
1009 *) Change the make targets and rules to be consistent in all of the
1010 Apache-owned source trees. [Roy Fielding]
1012 *) Fix processing of the TRACE method. Previously we passed bogus
1013 parms to form_header_field() and it overlaid some vhost structures,
1014 resulting in a segfault in check_hostalias().
1015 [Greg Ames, Jeff Trawick]
1017 *) Win32: Add support for reliable piped logs. If the logging process
1018 goes down, Apache will automatically restart it. This function has
1019 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
1022 *) Do not start piped log processes during the config file
1023 preflight. This change also circumvents a problem on
1024 Windows where the rotatelog processes created during preflight
1025 was not getting cleaned up properly.
1028 *) add "Request Phase Participation" info to mod_info
1031 *) Make first phase changes to the scoreboard data structures in
1032 preparation for the rewriting of the scoreboard per my posted
1033 design notes. [Paul J. Reder]
1035 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
1036 and apr-util, allow it to be overridden by the configure command-line
1037 (default="--silent") and introduce LT_LDFLAGS to replace what we were
1038 formerly abusing as LTFLAGS. [Roy Fielding]
1040 *) Clean up the reporting of incorrect closing container tags.
1041 [Barrie Slaymaker <barries@slaysys.com>]
1043 *) Simplify the configure process by moving all libtool stuff to APR
1044 and moving hints.m4 inline. [Roy Fielding]
1046 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
1047 of functions used by mod_proxy for export in the DLL
1048 [Ian Holsman <IanH@cnet.com>]
1050 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
1051 request body from its stdin but no reqest body is being written to
1052 the cgi. [Jeff Trawick]
1054 *) mod_log_config: %c connection status incorrectly logged
1055 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
1058 *) Get mod_cern_meta working under Windows
1061 *) Create Files, and thus MMAPs, out of the request pool, not the
1062 connection pool. This solves a small resource leak that had us
1063 not closing files until a connection was closed. In order to do
1064 this, at the end of the core_output_filter, we loop through the
1065 brigade and convert any data we have into a single HEAP bucket
1066 that we know will survive clearing the request_rec.
1067 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
1070 *) Completely revamp configure so that it preserves the standard make
1071 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
1072 the configure additions to EXTRA_* variables. Also, allow the user
1073 to specify NOTEST_* values for all of the above, which eliminates the
1074 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
1075 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1076 avoid pointless duplications. Fix the order in which flags are given
1077 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1078 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1079 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1080 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1082 *) Get mod_tls to compile/work better on Windows. PR #7612
1083 [Bernhard Schrenk <b.schrenk@improx.com>]
1085 *) Fix shutdown/restart hangs in the threaded MPM.
1086 [Jeff Trawick, Greg Ames, Ryan Bloom]
1088 *) Removed the keptalive boolean from conn_rec because it is now only
1089 used by a single routine and can be replaced by a local variable.
1090 [Greg Stein, Ryan Bloom, Roy Fielding]
1092 *) Patch prefork to put enough of the signal processing back in so that
1093 signals are all handled properly now. The previous patch fixed the
1094 deadlock race condition, but broke the user directed signal handling.
1095 This fixes it to work the way it did before my previous prefork patch
1096 (primarily, SIGTERM is now working).
1098 *) Change how input filters decide how much data is returned to the
1099 higher filter. We used to use a field in the conn_rec, with this
1100 change, we use an argument to ap_get_brigade to determine how much
1101 data is retrieved. [Ryan Bloom]
1103 *) Fix seg fault at start-up introduced by Ryan's change to enable
1104 modules to specify their own logging tags. mod_log_config
1105 registers an optional function, ap_register_log_handler().
1106 ap_register_log_handler() was being called by http_core before
1107 the directive hash table was created. This patch creates the
1108 directive hash table before ap_register_log_handler() is
1109 registered as an optional function.
1110 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1112 *) Add ap_set_int_slot() function
1113 [John K. Sterling <sterling@covalent.net>]
1115 *) Under certain circumstances, Apache did not supply the
1116 right response headers when requiring authentication.
1117 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1118 (This is a port of the change that went into Apache 1.3.19.)
1120 *) Allow modules to specify their own logging tags. This basically
1121 allows a module to tell mod_log_config that when %x is encountered
1122 a specific function should be called. Currently, x can be any single
1123 character. It may be more useful to make this a string at some point.
1126 Changes with Apache 2.0.17
1128 *) If a higher-level filter handles the the byterange aspects of a
1129 request, then the byterange filter should not try to redo the
1130 work. The most common case of this happening, is a byterange
1131 request going through the proxy, and the origin server handles
1132 the byterange request. The proxy should ignore it.
1133 [Graham Leggett <minfrin@sharp.fm>]
1135 *) Changed the threaded mpm to have child_main join to each of the
1136 worker threads to make sure the kids are all gone before child_main
1137 exits after a signal (cleanup from perform_idle_server_maintenance).
1138 This is an extension of Ryans recent commit to make the child_main
1141 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1142 report if their threads are dynamic or static. Finally, this also
1143 implements a new API, ap_show_mpm, which returns the MPM that was
1144 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1146 *) Do not install the binaries from the support directory twice.
1147 [jun-ichiro hagino <itojun@iijlab.net>]
1149 *) The ap_f* functions should flush data to the filter that is passed
1150 in, not the the filter after the one passed in.
1151 [Ryan Morgan <rmorgan@covalent.net>]
1153 *) Make ab work again by changing its native types to apr types and formats.
1154 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1156 *) Move the byterange filter and all of the supporting functions back
1157 to the HTTP module. The byterange filter turned out to be very
1158 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1160 *) Make clean, distclean, and extraclean consistently according to the
1161 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1163 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1164 This may have been causing problems stopping processes in the threaded
1167 *) Fix content-length in mod_negotiation to a long int representation.
1170 *) Remove BindAddress from the default config file.
1171 [giles@nemeton.com.au]
1173 *) Allow module authors to add a module to their Apache build using
1174 --with-module, without re-running buildconf. The syntax is:
1175 --with-module=module_type:/path/to/module.c
1176 The configure script will copy the module.c file to
1177 modules/module_type, and it will be added to the relevant Makefiles.
1178 currently, this only works for static modules. [Ryan Bloom]
1180 *) Changes required to make prefork clean up idle children properly.
1181 There was a window during which a starting worker deadlocks when
1182 an idle cleanup arrives before it completes init. Apache then keeps
1183 trying to cleanup the same deadlocked worker forever (until higher
1184 pids come along, but it still will never reduce below the deadlocked
1185 pid). Thus the number of children would not reduce to the correct
1186 idle level. [Paul J. Reder]
1188 Changes with Apache 2.0.16
1190 *) Change the default installation directory to /usr/local/apache2,
1191 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1193 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1196 *) Get MaxRequestsPerChild working with the Windows MPM.
1199 *) Make generic hooks to work, with mod_generic_hook_import/export
1200 experimental modules. [Ben Laurie, Will Rowe]
1202 *) Fix segfaults for configuration file syntax errors such as
1203 "<Directory>" followed by "</Directory" and
1204 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1206 *) Cleanup the --enable-layout option of configure. This makes
1207 us use a consistent location for the config.layout file, and it
1208 makes configure more portable.
1209 [jun-ichiro hagino <itojun@iijlab.net>]
1211 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1212 csv/gnuplot format, rudimentary ssl support and various other tweaks
1213 to make results more true to what is measured. The upshot of this it
1214 turns out that 'ab' has often underreported the true performance of
1215 apache. Often by a order of magnitude :-) See talk/paper of Sander
1216 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1217 [Dirk-Willem van Gulik]
1219 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1220 storage leak this ensures that some unnecessary pipes are closed.
1223 *) Performance: Add quick_handler hook. This hook is called at the
1224 very beginning of the request processing before location_walk,
1225 translate_name, etc. This hook is useful for URI keyed content
1226 caches like Mike Abbott's Quick Shortcut Cache.
1229 *) top_module global variable renamed to ap_top_module [Perl]
1231 *) Move ap_set_last_modified to the core. This is a potentially
1232 controversial change, because this is kind of HTTP specific. However
1233 many protocols should be able to take advantage of this kind of
1234 information. I expect that headers will need one more layer of
1235 indirection for multi-protocol work, but this is a small step in
1236 the right direction. [Ryan Bloom]
1238 *) Enable mod_status by default. This matches what Apache 1.3 does.
1241 *) Add a ScriptSock directive to the default config file. This is
1242 only enabled when mod_cgid is used.
1243 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1245 Changes with Apache 2.0.15
1247 *) Untangled the buildconf script and eliminated the need for build's
1248 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1249 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1251 *) Win32: Don't accept more connections than we have worker threads
1255 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1256 to fork() new child processes.
1259 *) Fix a major security problem with double-reverse lookup checking.
1260 Previously, a client connecting over IPv4 would not be matched
1261 properly when the server had an IPv6 listening socket. PR #7407
1262 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1264 *) Change the way the beos MPM handles polling to allow it to stop and
1265 restart. Problem was the sockets being polled were being reset by
1266 the select call, so once it had accepted a connection it was no
1267 longer listening on the UDP socket we use for shutdown instructions.
1268 APR needs to be altered, patch on it's way. [David Reid]
1270 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1271 on error exit from ap_getline(). Some other code got upset because
1272 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1274 *) Handle ap_discard_request_body() being called more than once.
1275 [Greg Ames, Jeff Trawick]
1277 *) Get rid of an inadvertent close of file descriptor 2 in
1278 mod_mime_magic. [Greg Ames, Jeff Trawick]
1280 *) Add a hook, create_request. This hook allows modules to modify
1281 a request while it is being created. This hook is called for all
1282 request_rec's, main request, sub request, and internal redirect.
1283 When this hook is called, the the r->main, r->prev, r->next
1284 pointers have been set, so modules can determine what kind of
1285 request this is. [Ryan Bloom]
1287 *) Cleanup the build process a bit more. The Apache configure
1288 script no longer creates its own helper scripts, it just
1290 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1292 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1293 proxy requests. [Graham Leggett]
1295 *) Avoid using sscanf to determine the HTTP protocol number in
1296 the common case because sscanf is a performance hog. From
1297 Mike Abbot's Accelerating Apache patch number 6.
1298 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1300 *) Fix a security exposure in mod_access. Previously when IPv6
1301 listening sockets were used, allow/deny-from-IPv4-address rules
1302 were not evaluated properly (PR #7407). Also, add the ability to
1303 specify IPv6 address strings with optional prefix length on Allow
1304 and Deny. [Jeff Trawick]
1306 *) Enhance rotatelogs so that a UTC offset can be specified, and
1307 the logfile name can be formatted using strftime(3). (Brought
1308 forward from 1.3.) [Ken Coar]
1310 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1311 DuplicateHandle on an IOCompletionPort (a practice which
1312 MS "discourages"). The new model does not rely on associating
1313 the completion port with the listening sockets, thus the
1314 completion port can be completely managed within the child
1315 process. A dedicated thread accepts connections off the network,
1316 then calls PostQueuedCompletionStatus() to wake up worker
1317 threads blocked on the completion port.
1320 *) Bring forward the --suexec-umask option which allows the
1321 builder to preset the umask for suexec processes. [Ken Coar]
1323 *) Add a -V flag to suexec, which causes it to display the
1324 compile-time settings with which it was built. (Only
1325 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1327 *) Mod_include should always unset the content-length if the file is
1328 going to be passed through send_parsed_content. There is no to
1329 determine if the content will change before actually scanning the
1330 entire content. It is far safer to just remove the C-L as long
1331 as we are scanning it. [Ryan Bloom]
1333 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1334 request and not Proxy-Authenticate.
1335 [Graham Leggett <minfrin@sharp.fm>]
1337 Changes with Apache 2.0.14
1339 *) Fix content-length computation. We ONLY compute a content-length if
1340 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1341 or we already have all the data. [Ryan Bloom]
1343 *) Report unbounded containers in the config file. Previously, a typo
1344 in the </container> directive could result in the rest of the config
1345 file being silently ignored, with undesired defaults used.
1348 *) Make the old_write filter use the ap_f* functions for the buffering.
1351 *) Move more code from the http module into the core server. This
1352 is core code, basically the default handler, the default input
1353 and output filters, and all of the core configuration directives.
1354 All of this code is required in order for the server to work, with or
1355 without HTTP. The server is closer to working without the HTTP
1356 module, although there is still more to do. [Ryan Bloom]
1358 *) Fix a number of SGI compile warnings throughout the server. Fix some
1359 bad parameters to apr_bucket_read(). Fix a bad statement in
1360 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1361 consistently; we were mixing apr_time_t and time_t in invalid ways
1362 before. In load_file(), call apr_dso_error() instead of
1363 apr_strerror() so that we get a more specific string on some platforms.
1364 PR #6980 [Jeff Trawick]
1366 *) Allow modules to query the MPM about it's execution profile. This
1367 query API can and should be extended in the future, but for now,
1368 max_daemons, and threading or forking is a very good start.
1369 [Jon Travis <jtravis@covalent.net>]
1371 *) Modify mod_include to send blocks of data no larger than 9k.
1372 Without this, mod_include will wait until the whole file is parsed,
1373 or the first tag is found to send any data to the client.
1374 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1376 *) Fix mod_info, so that <Directory> and <Location> directives are
1377 not displayed twice when displaying the current configuration.
1378 [Ryan Morgan <rmorgan@covalent.net>]
1380 *) Add config directives to override DEFAULT_ERROR_MSG and
1381 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1382 [Dan Rench <drench@xnet.com>]
1384 *) Get mod_info building and loading on Win32. [William Rowe]
1386 *) Begin to move protocol independant functions out of mod_http. The goal
1387 is to have only functions that are HTTP specific in the http directory.
1390 Changes with Apache 2.0.13
1392 *) Don't assume that there will always be multiple calls to the byterange
1393 filter. It is possible that we will need to do byteranges with only
1394 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1396 *) Move the error_bucket definition from the http module to the
1397 core server. Every protocol will need this ability, not just
1400 Changes with Apache 2.0.12
1402 *) Modify mod_file_cache to save pre-formatted strings for
1403 content-length and last-modified headers for performance.
1404 [Mike Abbot <mja@trudge.engr.sgi.com>]
1406 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1407 [Jon Travis <jtravis@covalent.net>]
1409 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1410 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1412 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1413 without ever filling it out. This fixes PR 7271.
1414 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1415 Cliff Woolley <cliffwoolley@yahoo.com>]
1417 *) Add a couple of GCC attribute tags to printf style functions.
1418 [Jon Travis <jtravis@covalent.net>]
1420 *) Add the correct language tag for interoperation with the Taiwanese
1421 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1423 *) Migrate the perchild MPM to use the new apr signal child, and
1424 APR thread functions. [Ryan Bloom]
1426 *) Close one copy of the CGI's stdout before creating the new process.
1427 The CGI will still have stdout, because we have already dup'ed it.
1428 This keeps Apache from waiting forever to send the results of a CGI
1429 process that has forked a long-lived child process.
1430 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1432 *) Remove the rest of the pthreads functions from the threaded MPM.
1433 This requires the APR support for a signal thread that was just
1436 *) Make mod_dir use a fixup for sending a redirect to the browser.
1437 Before this, we were using a handler, which doesn't make much
1438 sense, because the handler wasn't generating any data, it would
1439 either return a redirect error code, or DECLINED. This fits the
1440 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1442 *) Make the threaded MPM use APR threads instead of pthreads.
1445 *) Get mod_tls to the point where it actually appears to work in all cases.
1448 *) implement --enable-modules and --enable-mods-shared for "all" and
1449 "most". [Greg Stein]
1451 *) Move the threaded MPM to use APR locks instead of pthread locks.
1454 *) Rename mpmt_pthread to threaded. This is more in line with the
1455 fact that mpmt_pthread shouldn't be using pthreads directly, and
1456 it is a smaller name that doesn't tie into anything.
1459 *) Rename the module structures so that the exported symbol matches
1460 the file name, and it is easier to automate the installation
1461 process (generating LoadModule directives from the module filenames).
1464 *) Remove the coalesce filter. With the ap_f* functions, this filter
1465 is no longer needed. [Ryan Bloom]
1467 Changes with Apache 2.0.11
1469 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1470 added feature of allowing a uid/gid per child process. If no
1471 uid/gid is specified, then Perchild behaves exactly like dexter.
1474 *) Get perchild building again. [Ryan Bloom]
1476 *) Don't disable threads just because we are using the prefork MPM.
1477 If somebody wants to compile without threads, they must now add
1478 --disable-threads to the configure command line. [Ryan Bloom]
1480 *) Begin to move the calls to update_child_status into common code, so
1481 that each individual MPM does not need to update the scoreboard itself.
1484 *) Allow mod_tls to compile under Unix boxes where openssl has been
1485 installed to the system include files.
1486 [Gomez Henri <new-httpd@slib.fr>]
1488 *) Cleanup the mod_tls configure process. This should remove any need
1489 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1490 configure doesn't check that yet. [Ryan Bloom]
1492 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1493 vital that you read modules/tls/README before attempting to build
1496 *) Fix a potential seg fault on all platforms. David Reid fixed this
1497 on BEOS, but the problem could happen anywhere, so we don't want
1498 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1500 *) Add new LogFormat directive, %D, to log time it takes to serve a
1501 request in microseconds. [Bill Stoddard]
1503 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1504 SetOutputFilter. This corresponds nicely with the other Set
1505 directives, which operate on containers while the Add* directives
1506 tend to work directly on extensions. [Ryan Bloom]
1508 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1509 functions for the buffering so that we don't need to compute
1510 the length of the headers before we actually create the header
1511 buffer. [Ryan Bloom]
1513 *) Allow filters to buffer data using the ap_f* functions. These have
1514 become macros that resolve directly to apr_brigade_*.
1517 *) Get the Unix MPM's to do a graceful restart again. If we are going
1518 to register a cleanup with ap_cleanup_scoreboard, then we have to
1519 kill the cleanup with the same function, and that function can't be
1520 static. [Ryan Bloom]
1522 *) Install all required header files. Without these, it was not
1523 possible to compile some modules outside of the server.
1526 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1527 forward from 1.3 to 2.0, we missed a single line, which broke regex
1528 aliases. [Ryan Bloom]
1530 *) We have a poor abstraction in the protocol. This is a temporary
1531 hack to fix the bug, but it will need to be fixed for real. If
1532 we find an error while sending out a custom error response, we back
1533 up to the first non-OK request and send the data. Then, when we send
1534 the EOS from finalize_request_protocol, we go to the last request,
1535 to ensure that we aren't sending an EOS to a request that has already
1536 received one. Because the data is sent on a different request than
1537 the EOS, the error text never gets sent down the filter stack. This
1538 fixes the problem by finding the last request, and sending the data
1539 with that request. [Ryan Bloom]
1541 *) Make the server status page show the correct restart time, and
1542 thus the proper uptime. [Ryan Bloom]
1544 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1545 should reduce the amount of duplicate code that is required to
1546 create CGI processes.
1547 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1549 *) ap_new_connection() closes the socket and returns NULL if a socket
1550 call fails. Usually this is due to a connection which has been
1551 reset. [Jeff Trawick]
1553 *) Move the Apache version information out of httpd.h and into release.h.
1554 This is in preparation for the first tag with the new tag and release
1555 system. [Ryan Bloom]
1557 *) Begin restructuring scoreboard code to enable adding back in
1558 the ability to use IPC other than shared memory.
1559 Get mod_status working on Windows again. [Bill Stoddard]
1561 *) Make mod_status work with 2.0. This will work for prefork,
1562 mpmt_pthread, and dexter. [Ryan Bloom]
1564 *) Correct a typo in httpd.conf.
1565 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1567 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1569 *) Get the correct IP address if ServerName isn't set and we can't
1570 find a fully-qualified domain name at startup.
1571 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1573 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1575 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1576 'extra' stat's for user/group since they should never occur, and now
1577 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1578 volumes. [William Rowe]
1580 *) Adopt apr features to simplify mod_includes. This changes the
1581 behavior of the USER_NAME variable, unknown uid's are now reported
1582 as USER_NAME="<unknown>" rather than the old user#000 result.
1583 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1585 *) Adopt apr features for simplifing mod_userdir, and accept the new
1586 Win32/OS2 exceptions without hiccuping. [William Rowe]
1588 *) Replace configure --with-optim option by using and saving the
1589 environment variable OPTIM instead. This is needed because configure
1590 options do not support multiple flags separated by spaces.
1593 *) Fix some byterange handling. If we get a byte range that looks like
1594 "-999999" where that is past the end of the file, we should return
1595 a PARTIAL CONTENT status code, and return the whole file as one big
1596 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1598 *) Make the error bucket a real meta-data bucket. This means that the
1599 bucket length is 0, and a read returns NULL data. If one of these
1600 buckets is passed down after the headers are sent, this data will
1601 just be ignored. [Greg Stein]
1603 *) The prefork MPM wasn't killing child processes correctly if a restart
1604 signal was received while the process was serving a request. The child
1605 process would become the equivalent of a second parent process. If
1606 we break out of the accept loop, then we need to do die after cleaning
1607 up after ourselves. [Ryan Bloom]
1609 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1610 restarts. [Ryan Bloom]
1612 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1613 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1614 performing very expensive owner, group and permission lookups
1615 and allows the server to function until these apr_finfo_t fields
1616 are implemented under Win32. [William Rowe]
1618 *) Support for typedsafe optional functions - that is functions exported by
1619 optional modules, which, therefore, may or may not be present, depending
1620 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1621 for sample code. [Ben Laurie]
1623 *) filters can now report an HTTP error to the server. This is done
1624 by sending a brigade where the first bucket is an error_bucket.
1625 This bucket is a simple bucket that stores an HTTP error and
1626 a string. Currently the string is not used, but it may be needed
1627 to output an error log. The http_header_filter will find this
1628 bucket, and output the error text, and then return
1629 AP_FILTER_ERROR, which informs the server that the error web page
1630 has already been sent. [Ryan Bloom]
1632 *) If we get an error, then we should remove all filters except for
1633 those critical to serving a web page. This fixes a bug, where
1634 error pages were going through the byterange filter, even though
1635 that made no sense. [Ryan Bloom]
1637 *) Relax the syntax checking of Host: headers in order to support
1638 iDNS. PR#6635 [Tony Finch]
1640 *) Cleanup the byterange filter to use the apr_brigade_partition
1641 and apr_bucket_copy functions. This removes a lot of very messy
1642 code, and hopefully makes this filter more stable.
1645 *) Remove AddModule and ClearModuleList directives. Both of these
1646 directives were used to ensure that modules could be enabled
1647 in the correct order. That requirement is now gone, because
1648 we use hooks to ensure that modules are in the correct order.
1651 *) When SuExec is specified, we need to add it to the list of
1652 targets to be built. If we don't, then any changes to the
1653 configuration won't affect SuExec, unless 'make suexec' is
1654 specifically run. [Ryan Bloom]
1656 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1657 the APR_XTHREAD argument to open a file for consumption by
1658 parallel threads on win32. [William Rowe]
1660 *) Correct a bug in determining when we follow symlinks. The code
1661 expected a stat -1 result, not an apr_status_t positive error.
1662 Also check if the APR_FINFO_USER fields are valid before we
1663 follow the link. [William Rowe]
1665 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1666 mpm_common.c. These functions are only valid on some platforms,
1667 so they should not be in the main-line code. [Ryan Bloom]
1669 *) Remove ap_chdir_file(). This function is not thread-safe,
1670 and nobody is currently using it. [Ryan Bloom]
1672 *) Do not try to run make depend if there are no .c files in the
1673 current directory, doing so makes `make depend` fail.
1676 *) Update highperformance.conf to work with either prefork or
1677 pthreads mpms. [Greg Ames]
1679 *) Stop checking to see if this is a pipelined request if we know
1680 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1681 This keeps us from making an extra read call when serving a 1.0
1682 request. [Ryan Bloom and Greg Stein]
1684 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1685 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1686 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1688 *) Fix the RFC number mentioned when complaining about a missing
1689 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1691 *) Fix an endless loop in ab which occurred when ab was posting
1692 and the server dropped the connection unexpectedly.
1695 *) Fix a segfault while handling request bodies in ap_http_filter().
1696 This problem has been seen with mod_dav usage as well as with
1697 requests where the body was just being discarded. [Jeff Trawick]
1699 *) Some adjustment on the handling and automatic setting (via
1700 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1701 add the capability to specify flags (NOTEST_CFLAGS and
1702 NOTEST_LDFLAGS) which are used to compile Apache, but
1703 not used during the configuration process. Useful for
1704 flags like "-Werror". [Jim Jagielski]
1706 *) Stop using environment variables to force debug mode or
1707 no detach. We now use the -D command line argument to
1708 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1709 [Greg Stein, Ryan Bloom]
1711 *) Change handlers to use hooks. [Ben Laurie]
1713 *) Stop returning copies of filenames from both apr_file_t and
1714 apr_dir_t. We pstrdup the filenames that we store in the
1715 actual structures, so we don't need to pstrdup the strings again.
1718 *) mod_cgi: Fix some problems where the wrong error value was being
1719 traced. [Jeff Trawick]
1721 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1724 *) Add generic hooks. [Ben Laurie]
1726 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1728 *) Fix a segfault caused by mod_ext_filter when the external filter
1729 program does not exist. [Jeff Trawick]
1731 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1732 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1733 was served through mod_charset_lite (or anything else that would
1734 create a transient bucket in this size range). ap_bucket_make_heap()
1735 silently failed (fixed), transient_setaside() discovered it, but
1736 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1738 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1739 is that some browsers send extra lines at the end of POST requests, and
1740 we don't want to delay sending data back to the user just because the
1741 browser isn't well behaved. [Ryan Bloom]
1743 *) Get SuEXEC working again. We can't send absolute paths to suExec
1744 because it refuses to execute those programs. SuEXEC also wasn't
1745 always recognizing configuration changes made using the autoconf
1748 *) Allow the buildconf process to find the config.m4 files in the correct
1749 order. Basically, we can now name config.m4 files as config\d\d.m4,
1750 and we will sort them correctly when inserting them into the build
1751 process. [Ryan Bloom]
1753 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1754 This also allows mod_cgid to use ap_os_create_priviledged_process,
1755 thus allowing for SuExec execution from mod_cgid. Currently, we do
1756 not support everything that standard SuExec supports, but at least
1757 it works minimally now. [Ryan Bloom]
1759 *) Allow SuExec to be configured from the ./configure command line.
1762 *) Update some of the docs in README and INSTALL to reflect some of
1763 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1765 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1766 need to call sendfile again. This gets us serving large files
1767 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1769 *) Get the support programs building cleanly again.
1770 [Cliff Woolley <cliffwoolley@yahoo.com>]
1772 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1773 current directory logic now backs up over bin/ to determine the
1774 server root from the Apache.exe path.
1776 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1777 loadable modules, dynamic libs are all named libfoo.dll, and the
1778 makefile.win populates the include, lib and libexec directories.
1780 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1781 Apache gets IPv6 listening sockets by default. Additionally, the
1782 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1783 numeric address strings (e.g., "Listen [fe80::1]:8080").
1786 *) Modify the install directory layout. Modules are now installed in
1787 modules/. Shared libraries should be installed in libraries/, but
1788 we don't have any of those on Unix yet. All install directories
1789 are modifyable at configure time. [Ryan Bloom]
1791 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1793 *) Get the functions in server/linked into the server, regardless of
1794 which modules linked into the server. This uses the same hack
1795 for Apache that we use for APR and apr-util to ensure all of the
1796 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1797 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1798 the scripts a bit easier.
1801 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1802 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1804 *) Get all of the auth modules to the point that they will install and
1805 be loadable into the server. Our new build/install mechanism expects
1806 that all modules will have a common name format. The auth modules
1807 didn't use that format, so we didn't install them properly.
1810 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1811 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1813 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1815 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1816 after the end of the response. [Ryan Bloom]
1818 *) Get byterange requests working with responses that do not have a
1819 content-length. Because of the way byterange requests work, we have to
1820 have all of the data before we can actually do the byterange, so we
1821 can compute the content-length in the byterange filter.
1824 *) Get exe CGI's working again on Windows.
1827 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1828 they keep track of whether or not their post config hook has been
1829 called before. Instead of a static variable (which is replaced when
1830 the DSO is loaded a second time), use userdata in the process pool.
1833 Changes with Apache 2.0a9
1835 *) Win32 now requires perl to complete the final install step for users
1836 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1837 and installs the conf, htdocs and htdocs/manual directories.
1840 *) Make mod_include use a hash table to associate directive tags with
1841 functions. This allows modules to implement their own SSI tags easily.
1842 The idea is simple enough, a module can insert it's own tag and function
1843 combination into a hash table provided by mod_include. While mod_include
1844 parses an SSI file, when it encounters a tag in the file, it does a
1845 hash lookup to find the function that implements that tag, and passes
1846 all of the relevant data to the function. That function is then
1847 responsible for processing the tag and handing the remaining data back
1848 to mod_include for further processing.
1849 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1851 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1852 fewer parameters: the local and remote socket addresses were removed
1853 from the parameter list because all required information is available
1854 via the APR socket. [Jeff Trawick]
1856 *) Distribution directory structure reorganized to reflect a
1857 normal source distribution with external install targets.
1860 *) The MPMs that need multiple segments of shared memory now create
1861 two apr_shmem_t variables, one for each shared memory allocation.
1862 the problem is that we can't determine how much memory will be required
1863 for shared memory allocations once we try to allocate more than one
1864 variable. The MM code automatically aligns the shared memory allocations,
1865 so we end up needing to pad the amount of shared memory we want based
1866 on how many variables will be allocated out of the shared memory segment.
1867 It is just easier to create a second apr_shmem_t variable, and two
1868 shmem memory blocks.
1871 *) Cleanup the export list a bit. This creates a single unified list of
1872 functions exported by APR. The export list is generated at configure
1873 time, and that list is then used to generate the exports.c file.
1874 Because of the way the export list is generated, we only export those
1875 functions that are valid on the platform we are building on.
1878 *) Enable logging the cookie with mod_log_config
1879 [Sander van Zoest <sander@covalent.net>]
1881 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1884 *) Added lib/aputil/ as a placeholder for utility functions which are not
1885 specific to the Apache HTTP Server (but do not make sense with APR).
1886 The first utility is "apu_dbm": a set of functions to work with DBM
1887 files. This first version can be compiled for SDBM or GDBM databases.
1890 *) Complete re-write of mod_include. This makes mod_include a filter that
1891 uses buckets directly. This has now served the FAQ correctly.
1892 [Paul Reder <rederpj@raleigh.ibm.com>]
1894 *) Allow modules to specify the first filter in a sub_request when
1895 making the sub_request. This keeps modules from having to change the
1896 output_filter immediately after creating the sub-request, and therefore
1897 skip the sub_req_output_filter. [Ryan Bloom]
1899 *) Update ab to accept URLs with IPv6 literal address strings (in the
1900 format described in RFC 2732), and to build Host header fields in
1901 the same format. This allows IPv6 literal address strings to be
1902 used with ab. This support has been tested against Apache 1.3 with
1903 the KAME patch, but Apache 2.0 does not yet work with this format
1904 of the Host header field. [Jeff Trawick]
1906 *) Accomodate an out-of-space condition in the piped logs and the
1907 rotatelogs.c code, and no longer churn log processes for this
1908 condition. [Victor J. Orlikowski]
1910 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1913 Changes with Apache 2.0a8
1915 *) Add a directive to mod_mime so that filters can be associated with
1919 *) Get multi-views working again. We were setting the path_info
1920 field incorrectly if we couldn't find the specified file.
1923 *) Fix 304 processing. The core should never try to send the headers
1924 down the filter stack. Always, just setup the table in the request
1925 record, and let the header filter convert it to data that is ready
1929 *) More fixes for the proxy. There are still bugs in the proxy code,
1930 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1934 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1937 *) APR: Add new apr_getopt_long function to handle long options.
1938 [B. W. Fitzpatrick <fitz@red-bean.com>]
1940 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1941 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1942 hostname resolution/address string parsing and building
1943 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1944 of one of the apr_sockaddr_t structures for a socket. Change
1945 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1947 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1948 I have proxied pages with it, cleanup will commence soon.
1951 *) Make the proxy work with filters. This isn't perfect, because we
1952 aren't dealing with the headers properly. [Ryan Bloom]
1954 *) Do not send a content-length iff the C-L is 0 and this is a head
1955 request. [Ryan Bloom]
1957 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1958 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1960 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1962 *) Get the default_handler to stop trying to deal with HEAD requests.
1963 The idea is to let the content-length filter compute the C-L before
1964 we try to send the data. If we can get the C-L correctly, then we
1965 should send it in the HEAD response.
1968 *) The Header filter can now determine if a body should be sent based
1969 on r->header_only. The general idea of this is that if we delay
1970 deciding to send the body, then we might be able to compute the
1971 content-length correctly, which will help caching proxies to cache
1972 our data better. Any handler that doesn't want to try to compute
1973 the content-length can just send an EOS bucket without data and
1974 everything will just work.
1977 *) Add the referer to the error log if one is available.
1978 [Markus Gyger <mgyger@itr.ch>]
1980 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1981 change, the root of the configuration tree has been exposed to modules
1983 [Ryan Morgan <rmorgan@covalent.net>]
1985 *) Get the core_output_filter to use the bucket interface directly.
1986 This keeps us from calling the content-length filter multiple times
1987 for a simple static request.
1990 *) We are sending the content-type correctly now.
1991 [Ryan Bloom and Will Rowe]
1993 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1994 a bogus bytes-sent value when the only thing being sent was trailers
1995 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1997 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1998 hints file to determine which platforms define
1999 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
2002 *) APR: add apr_get_home_directory() [Jeff Trawick]
2004 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
2006 *) Not all platforms have INADDR_NONE defined by default. Apache
2007 used to make this check and define INADDR_NONE if appropriate,
2008 but APR needs the check too, and I suspect other applications will
2009 as well. APR now defines APR_INADDR_NONE, which is always a valid
2010 value on all platforms.
2011 [Branko Èibej <brane@xbc.nu>]
2013 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
2014 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
2016 *) Relax the syntax checking of Host: headers in order to support
2017 iDNS. PR#6635 [Tony Finch]
2019 *) When reading from file buckets we convert to an MMAP if it makes
2020 sense. This also simplifies the default handler because the
2021 default handler no longer needs to try to create MMAPs.
2024 *) BUFF has been removed from the main server. The BUFF code will remain
2025 in the code until it has been purged from the proxy module as well.
2028 *) Byteranges have been completely re-written to be a filter. This
2029 has been tested, and I believe it is working correctly, but it could
2030 doesn't work for the Adobe Acrobat plug-in. The output almost matches
2031 the output from 1.3, the only difference being that 1.3 includes
2032 a content-length in the response, and this does not.
2035 *) APR read/write functions and bucket read functions now operate
2036 on unsigned integers, instead of signed ones. It doesn't make
2037 any sense to use signed ints, because we return the error codes,
2038 so if we have an error we should report 0 bytes read or written.
2041 *) Always compute the content length, whether it is sent or not.
2042 The reason for this, is that it allows us to correctly report
2043 the bytes_sent when logging the request. This also simplifies
2044 content-length filter a bit, and fixes the actual byte-reporing
2045 code in mod_log_config.c
2048 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
2049 it says, because it was only used by EOS and FLUSH buckets. Since
2050 neither of those are required at the end of a brigade, this was
2051 really signifying FLUSH_THE_DATA, but that can be determined better
2052 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
2053 buckets now return a length of 0, which is actually the amount of data
2054 read, so they make more sense.
2057 *) Allow the core_output_filter to save some data past the end of a
2058 request. If we get an EOS bucket, we only send the data if it
2059 makes sense to send it. This allows us to pipeline request
2060 responses. As a part of this, we also need to allocate mmap
2061 buckets out of the connection pool, not the request pool. This
2062 allows the mmap to outlive the request.
2065 *) Make blocking and non-blocking bucket reads work correctly for
2066 sockets and pipes. These are the only bucket types that should
2067 have non-blocking reads, because the other bucket types should
2068 ALWAYS be able to return something immediately.
2071 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
2072 server, but use Ctrl+Break to initiate a graceful restart
2073 instead of duplicating behavior. [John Sterling]
2075 *) Patch mod_autoindex to set the Last-Modified header based on
2076 the directory's mtime, and add the ETag header. [William Rowe]
2078 *) Merge the 1.3 patch to add support for logging query string in
2079 such a way that "%m %U%q %H" is the same as "%r".
2082 *) Port three log methods from mod_log_config 1.3 to 2.0:
2083 CLF compliant '-' byte count, method and protocol.
2086 *) Add a new LogFormat directive, %c, that will log connection
2087 status at the end of the response as follows:
2088 'X' - connection aborted before the response completed.
2089 '+' - connection may be kept-alive by the server.
2090 '-' - connection will be closed by the server.
2093 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2094 Unicode file names and paths for Win32, and tag the Content-Type
2095 from mod_autoindex to reflect that charset if the the feature
2096 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2098 *) Compute the content length (and add appropriate header field) for
2099 the response when no content length is available and we can't use
2100 chunked encoding. [Jeff Trawick]
2102 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2103 so that content input filters get dechunked data when using
2104 the default handler. Also removed REQUEST_CHUNKED_PASS.
2107 *) Add mod_ext_filter as an experimental module. This module allows
2108 the administrator to use external programs as filters. Currently,
2109 only filtering of output is supported. [Jeff Trawick]
2111 *) Most Apache functions work on EBCDIC machines again, as protocol
2112 data is now translated (again). [Jeff Trawick]
2114 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2115 the EBCDIC support. They are noops on ASCII machines, so this
2116 type of translation doesn't have to be surrounded by #ifdef
2117 CHARSET_EBCDIC. [Jeff Trawick]
2119 *) Fix mod_include. tag commands work again, and the server will
2120 send the FAQ again. This also allows mod_include to set aside
2121 buckets that include partial buckets.
2122 [Ryan Bloom and David Reid]
2124 *) Add suexec support back. [Manoj Kasichainula]
2126 *) Lingering close now uses the socket directly instead of using
2127 BUFF. This has been tested, but since all we can tell is that it
2128 doesn't fail, this needs to be really hacked on.
2131 *) Allow filters to modify headers and have those headers be sent to
2132 the client. The idea is that we have an http_header filter that
2133 actually sends the headers to the network. This removes the need
2134 for the BUFF to send headers.
2137 *) Charset translation: mod_charset_lite handles translation of
2138 request bodies. Get rid of the xlate version of ap_md5_digest()
2139 since we don't compute digests of filtered (e.g., translated)
2140 response bodies this way anymore. (Note that we don't do it at
2141 all at the present; somebody needs to write a filter to do so.)
2144 *) Input filters and ap_get_brigade() now have a input mode parameter
2145 (blocking, non-blocking, peek) instead of a length parameter.
2148 *) Update the mime.types file to the registered media types as
2149 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2152 *) Namespace protect some macros declared in ap_config.h
2155 *) Support HTTP header line folding with input filtering.
2158 *) Mod_include works again. This should still be re-written, but at
2159 least now we can serve an SHTML page again.
2162 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2163 to both the BUFF and the socket in the conn_rec. Functions that
2164 want to use the BUFF can, functions that want to use the socket,
2165 can. They point to the same place.
2168 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2169 [Tomas "Ögren" <stric@ing.umu.se>]
2171 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2172 associated pool goes away. (APR pipes on OS/2 were already had this
2173 logic.) This resolvs a fatal file descriptor leak with CGIs.
2176 *) The final line of the config file was not being read if there was
2177 no \n at the end of it. This was caused by apr_fgets returning
2178 APR_EOF even though we had read valid data. This is solved by
2179 making cfg_getline check the buff that was returned from apr_fgets.
2180 If apr_fgets return APR_EOF, but there was data in the buf, then we
2181 return the buf, otherwise we return NULL.
2184 *) Piped logs work again in the 2.0 series.
2187 *) Restore functionality broken by the mod_rewrite security fix:
2188 rewrite map lookup keys and default values are now expanded
2189 so that the lookup can depend on the requested URI etc.
2190 PR #6671 [Tony Finch]
2192 *) Tighten up the syntax checking of Host: headers to fix a
2193 security bug in some mass virtual hosting configurations
2194 that can allow a remote attacker to retrieve some files
2195 on the system that should be inaccessible. [Tony Finch]
2197 *) Add a pool bucket type. This bucket is used for data allocated out
2198 of a pool. If the pool is cleaned before the bucket is destroyed, then
2199 the data is converted to a heap bucket, allowing it to survive the
2203 *) Add a flush bucket. This allows modules to signal that the filters
2204 should all flush whatever data they currently have. There is no way
2205 to actually force them to do this, so if a filter ignores this bucket,
2206 that's life, but at least we can try with this.
2209 *) Add an output filter for sub-requests. This filter just strips the
2210 EOS bucket so that we don't confuse the main request's core output
2211 filter by sending multiple EOS buckets. This change also makes sub
2212 requests start to send EOS buckets when they are finished.
2215 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2216 makes ap_bucket_destroy a return void, which is okay because it
2217 used to always return APR_SUCCESS, and nobody ever checked its
2218 return value anyway.
2219 [Cliff Woolley <cliffwoolley@yahoo.com>]
2221 *) Remove the index into the bucket-type table from the buckets
2222 structure. This has now been replaced with a pointer to the
2223 bucket_type. Also add some macros to test the bucket-type.
2226 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2227 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2228 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2229 All _VAR_ flavors changes to _DATA to be absolutely clear.
2232 *) Add support for /, //, //servername and //server/sharename
2233 parsing of <Directory> blocks under Win32 and OS2.
2234 [Tim Costello, William Rowe, Brian Harvard]
2236 *) Remove the function pointers from the ap_bucket type. They have been
2237 replaced with a global table. Modules are allowed to register bucket
2238 types and use then use those buckets.
2241 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2242 once we finish writing the request body to the cgi child process;
2243 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2244 worked without this change (for reasons I don't understand), but large
2245 ones didn't. [Jeff Trawick]
2247 *) Remove file bucket specific information from the ap_bucket type.
2248 This has been moved to a file_bucket specific type that hangs off
2249 the data pointer in the ap_bucket type.
2252 *) Input filtering now has a third argument. This is the amount of data
2253 to read from lower filters. This argument can be -1, 0, or a positive
2254 number. -1 means give me all the data you have, I'll deal with it and
2255 let you know if I need more. 0 means give me one line and one line
2256 only. A positive number means I want no more than this much data.
2258 Currently, only 0 and a positive number are implemented. This allows
2259 us to remove the remaining field from the conn_rec structure, which
2263 *) Big cleanup of the input filtering. The goal is that http_filter
2264 understands two conditions, headers and body. It knows where it is
2265 based on c->remaining. If c->remaining is 0, then we are in headers,
2266 and http_filter returns a line at a time. If it is not 0, then we are
2267 in body, and http_filter returns raw data, but only up to c->remaining
2268 bytes. It can return less, but never more.
2269 [Greg Ames, Ryan Bloom, Jeff Trawick]
2271 *) mod_cgi: Write all of the request body to the child, not just what
2272 the kernel would accept on the first write. [Jeff Trawick]
2274 *) Back out the change that moved the brigade from the core_output_filters
2275 ctx to the conn_rec. Since all requests over a given connection
2276 go through the same core_output_filter, the ctx pointer has the
2280 *) Fix another bug in the send_the_file() read/write loop. A partial
2281 send by apr_send would cause unsent data in the read buffer to
2282 get clobbered. Complete making send_the_file handle partial
2283 writes to the network.
2286 *) Fix a couple of type fixes to allow compilation on AIX again
2287 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2289 *) Fix bug in send_the_file() which causes offset to be ignored
2290 if there are no headers to send.
2293 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2294 filter. Useful for supporting Windows 9* with a binary
2295 compiled on Windows NT.
2298 Changes with Apache 2.0a7
2300 *) Reimplement core_output_filter to buffer/save bucket brigades
2301 across multiple calls to the core_filter. The brigade will be
2302 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2303 thresholds are hit or the EOS bucket is received.
2306 *) Create experimental filter (buffer_filter) that coalesces bytes
2307 into one large buffer before invoking the next filter in the
2308 chain. This filter is particularly useful with the current
2309 implementation of mod_autoindex when it inserted above the
2310 chunk_filter. mod_autoindex generates a lot of brigades that
2311 containing buckets holding just a few bytes each. The
2312 buffer_filter coalesces these buckets into a single large bucket.
2315 *) Add apr_sendfile() support into the core_output_filter.
2318 *) Add apr_sendv() support into the core_output_filter.
2321 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2322 [Mike Abbott <mja@sgi.com>]
2324 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2325 make much sense, because Apache uses buckets instead of BUFFs now.
2328 *) send_the_file now falls back to a read/write loop on platforms that
2329 do not have sendfile.
2330 [Ryan Bloom and Brian Havard]
2332 *) Install apachectl correctly, and substitute the proper values so
2333 that it works again. [Ryan Bloom]
2335 *) Better(??) handle platforms that lack sendfile().
2338 *) APR now has UUID generation/formatting/parsing support.
2341 *) Begin the http_filter. This is an input filter that understands
2342 the absolute basic amount required to parse an HTTP Request. The
2343 goal is to be able to split headers from request body before passing
2344 the data back to the other filters.
2347 *) Bring forward from 1.3.13 the config directory implementation
2350 *) install apxs if it is created
2353 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2354 conversions. [William Rowe]
2356 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2357 ap_add_output_filter(). [Jeff Trawick]
2359 *) Multiple build and configuration fixes
2362 -add datadir and localstatedir substitutions
2364 -fix logfilename misspelling
2365 -fix evaluation of installation dir variables and
2366 -replace $foobar by $(foobar) to be usefull in the makefile
2370 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2371 $CC_FOR_BUILD is still missing
2372 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2373 -add missing "AR=@AR@" to severaly Makefile.in's
2374 -cache result for "struct rlimit"
2375 -compile all helper programs with native and cross compiler
2376 and use the native version to generate header file
2377 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2379 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2381 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2383 *) Fix a bug where a client which only sends \n to delimit header
2384 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2385 message. Start working on ebcdic co-existance with input
2387 [William Rowe, Greg Ames]
2389 *) If mod_so is enabled in the server always create libexec, even
2390 if there are no modules installed in this directory. This is a
2391 requirement for APXS to work correctly.
2394 *) Connection oriented output filters are now stored in the
2395 conn_rec instead of the request_rec. This allows us to add the
2396 output filter in the pre-connection phase instead of the
2397 post_read_request phase, which keeps us from trying to write an
2398 error page before we have a filter to write to the network.
2399 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2401 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2402 mmap can be used across multiple buckets (default_handler with
2403 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2404 the mmap itself can't be associated with the bucket.
2407 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2410 *) Radical surgery to improve mod_isapi support under Win32.
2411 Includes a number of newer ServerSupportFunction calls, support
2412 for ReadClient (in order to retrieve POSTs greater than 48KB),
2413 and general bug fixes to more reliably load ISAPI .dll's and
2414 prevent leaking handle resources. Note: There are still
2415 discrepancies between IIS's and Apache's ServerVariables, and
2416 async calls are still not supported. Additional warnings are
2417 logged to facilitate debugging of unsupported ISAPI calls.
2420 *) Add input filtering to Apache. The basic idea for the input
2421 filters is the same as the ideas for output filters. The biggest
2422 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2423 should be called, and the order of execution for the filter itself is
2424 different. When writing an output filter, a brigade is passed in,
2425 and filters operate directly on that brigade, when done, they call
2426 ap_pass_brigade. Input filters are the exact opposite. Because input
2427 is not a push operation, filters first call ap_get_brigade. When this
2428 function returns, the input filter will be left with a valid brigade.
2429 The input filter should then operate on the brigade, and return.
2432 *) Fix building on BSD/OS using its native make. The build system
2433 falls back to the BSD .include directive on that host platform.
2436 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2437 SHA1 and plaintext password encodings. Make feature tests a
2438 bit more flexible. [William Rowe]
2440 *) Charset translation: mod_charset_lite handles output content
2441 translation in a filter. mod_charset_lite no longer ignores
2442 subrequests. A bunch of cruft related to BUFF's support for
2443 translating request and response bodies was removed.
2446 *) Move the addition of the CORE filter to the post_read_request
2447 hook in http_core.c. This removes the need to add the filter in
2448 multiple places and allows for an SSL module to be added much
2449 simpler. [Ryan Bloom]
2451 *) Fix a security problem that affects certain configurations of
2452 mod_rewrite. If the result of a RewriteRule is a filename that
2453 contains expansion specifiers, especially regexp backreferences
2454 $0..$9 and %0..%9, then it may be possible for an attacker to
2455 access any file on the web server. [Tony Finch]
2457 *) Fix a bug where errors that are detected during early request parsing
2458 don't produce visible HTTP error messages at the browser, because
2459 the core_filter wasn't present. [Greg Ames]
2461 *) Provide apr_socklen_t as a portability aid.
2462 [Victor J. Orlikowski]
2464 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2465 as well as a comment arg to the add, adduser and update cmds.
2466 update allows the user to clear or preserve pw/groups/comment.
2467 Fixed a bug in dbmmanage that prevented the check option from
2468 parsing a password followed by :group... text. Corrected the
2469 seed calcualation for Win32 systems, and added -lsdbm support.
2472 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2475 *) Avoid a segfault when parsing .htaccess files. An
2476 uninitialized tree pointer was passed to ap_build_config().
2479 *) Change the way that inet_addr & inet_network are checked for
2480 in APR's configure process to allow BeOS BONE to correctly
2481 find them. With this change BeOS BONE now builds from source
2482 with no problems. [David Reid]
2484 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2485 the end of the parameters to execve() was stored in the wrong
2486 location, overlaying the storage beyond the newargs[] array and
2487 also passing uninitialized storage to execve(), which would
2488 sometimes fail with EFAULT. [Jeff Trawick]
2490 *) Fix a bug parsing configuration file containers. With a sequence
2491 like this in the config file
2493 <IfModule mod_kilroy.c>
2496 <IfModule mod_lovejoy.c>
2501 the second container would be terminated at the blank line due to
2502 sediment in the buffer from reading the prior </IfModule> and an
2503 error message would be generated for the real </IfModule> for the
2504 second container. Also due to this problem, any two characters
2505 could be used for "</" in the close of a container.
2508 *) ap_add_filter prototype changed to remove the ctx pointer. The
2509 pointer still remains in the filter structure, but it can not be
2510 a part of the ap_add_filter prototype. The reason is that when
2511 the core uses AddFilter to add a filter to the stack it doesn't
2512 know how to allocate the ctx pointer, or even how much memory should
2513 be allocated. The filters will have to be responsible for allocating
2514 the ctx memory when they need it.
2517 *) Add an AddFilter directive. This directive takes a list of filters
2518 that should be activated for the requested resource.
2521 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2522 some other platforms). [Jeff Trawick]
2524 *) Modify mod_include to be a filter. Currently, it has only been tested
2525 on actual files, but it should work for CGI scripts too.
2528 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2529 writes. apr_flush() for Unix: handle interrupted writes.
2532 *) NameVirtualHost can now take "*" as an argument instead of
2533 an IP address. This allows you to create a purely name-based
2534 virtual hosting server that does not have any IP addresses in
2535 the configuration file and which ignores the local address
2536 of any connections. PR #5595, PR #4455 [Tony Finch]
2538 *) Fix some compile warnings in mod_mmap_static.c
2539 [Mike Abbott <mja@sgi.com>]
2541 *) Fix chunking problem with CGI scripts. The general problem was that
2542 the CGI modules were adding an EOS bucket and then the core added an
2543 EOS bucket. The chunking filter finalizes the chunked response when it
2544 encounters an EOS bucket. Because two EOS buckets were sent, we
2545 finalized the response twice. The fix is to make sure we only send one
2546 EOS, by utilizing a flag in the request_rec.
2549 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2550 and Win32. Previously, the first read from an apr_file_t set up via
2551 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2553 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2554 bucket, instead of using BUFF's and ap_r*.
2557 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2558 [Mike Abbott <mja@sgi.com>]
2560 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2561 code to use APR file's directly instead of going through BUFFs.
2564 *) Fix compile break on some platforms for mod_mime_magic.c
2565 [John K. Sterling <sterling@covalent.net>]
2567 *) Fix merging of AddDefaultCharset directive.
2568 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2570 *) Minor revamp of the rlimit sections of code. We now test
2571 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2572 is now "available" even if the platform doesn't support
2573 the rlimit family (it's just a noop though). [Jim Jagielski]
2575 *) Migrate the pre-selection of which MPM to use for specific
2576 platforms to hints.m4, which contains (or should contain)
2577 all platform specific "hints". [Jim Jagielski]
2579 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2582 *) Add tables with non-string/binary values to APR.
2585 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2588 *) Update PCRE to version 3.2. [Ryan Bloom]
2590 *) Change the way buckets' destroy functions are called so that
2591 they can be more directly used when changing the type of a
2592 bucket in place. [Tony Finch]
2594 *) Add generic support for reference-counting the resources used by
2595 buckets, and alter the HEAP and MMAP buckets to use it. Change
2596 the way buckets are initialised to support changing the type of
2597 buckets in place, and use it when setting aside TRANSIENT buckets.
2598 Change the implementation of TRANSIENT buckets so that it can be
2599 mostly shared with IMMORTAL buckets, which are now implemented.
2602 Changes with Apache 2.0a6
2604 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2606 *) Add a chunking filter to Apache. This brings us one step closer
2607 to removing BUFF. [Ryan Bloom]
2609 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2610 added to the stack is the last filter to be called. [Ryan Bloom]
2612 *) Apache 2.0 has been completely documented using Scandoc. The
2613 docs can be generated by running 'make docs'. [Ryan Bloom]
2615 *) Add filtered I/O to Apache. This is based on bucket brigades,
2616 Currently the buckets still use BUFF under the covers, but that
2617 should change quickly. The only currently written filter is the
2618 core filter which just calls ap_bwrite. [The Apache Group]
2620 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2621 built with thread support. [Jeff Trawick]
2623 *) Abort configuration if --with-layout was specified and there's
2624 no layout definition file. [Ken Coar]
2626 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2628 *) Add support for extension methods for the Allow response header
2629 field, and an API routine for accessing r->allowed and the
2630 list of extension methods in a unified manner. [Ken Coar]
2632 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2633 [Rob Simonson <simo@us.ibm.com>]
2635 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2636 APACHE_XLATE builds. [Jeff Trawick]
2638 *) A configuration file parsing problem was fixed. When the
2639 configuration file started with an IfModule/IfDefine container,
2640 only the last statement in the container would be retained.
2643 Changes with Apache 2.0a5
2645 *) Perchild is serving pages after passing them to different child
2646 processes. There are still a lot of bugs, but this does work. I
2647 have made requests against the same installation of Apache, and had
2648 different servers use different user IDs to serve the responses.
2649 This change moves to using socketpair instead of an AF_UNIX socket.
2652 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2653 It can't seem to pass between child processes yet, but I think we
2654 are closer now than before. This moves us back to using Unix
2655 Domain Sockets. [Ryan Bloom]
2657 *) libapr functions and types renamed with apr_ prefix.
2658 #include "apr_compat.h" for 1.3.x backwards compat
2661 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2662 return the right information on the local socket address.
2663 [Gregory Nicholls <gnicholls@level8.com>]
2665 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2666 [Gregory Nicholls <gnicholls@level8.com>]
2668 *) Add an option to not detach from the controlling terminal without
2669 going into single process mode. This allows for much easier
2670 debugging of the process startup code. [Ryan Bloom]
2672 *) ab: don't use perror() to report the failure of an APR function.
2675 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2676 scoreboard on graceful restarts.
2679 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2680 An invalid ap_proc_t was passed to ap_create_process().
2683 *) Allow modules to register filters. Those filters are still
2684 never called, but this is a step in the right direction.
2685 [Ryan Bloom and Greg Stein]
2687 *) Register the mod_cgid daemon process for cleanup so that it is
2688 killed at termination if it does not die when the parent gets
2689 SIGTERM. This change is to fix occasional problems where the
2690 process stays around. Bugs in similar logic in mod_rewrite and
2691 mod_include were also fixed. [Jeff Trawick]
2693 *) Fix a bug in the time handling. Basically, we were imploding a time
2694 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2695 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2696 uses those two fields to adjust the time value. Because of the HTTP
2697 spec, both of those values can be zero'ed out safely. This fixes
2698 the bug correctly. [Ryan Bloom]
2700 *) Fix a couple of place in the Windows code where the wrong error
2701 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2703 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2705 *) Added the APR_EOL_STR macro for platform dependent differences in
2706 logfiles and other raw text (such as all APR files). Fixes logfiles
2707 not terminated with cr/lf sequences in Win32. [William Rowe]
2709 *) Move all strings functions in APR to src/lib/apr/strings and create
2710 apr_strings.h for the prototypes. [Ryan Bloom]
2712 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2713 to repeat the syscall until we stop getting EINTR. I noticed a
2714 related problem at termination (SIGTERM) on FreeBSD when using
2715 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2716 implementation work properly with child init. Previously, ap_lock()
2717 was essentially a no-op because all children were using different
2718 locks and thus nobody ever blocked. [Jeff Trawick]
2720 *) The htdocs/ tree has been moved out of the CVS source tree into
2721 a separate area for easier development. This has NO EFFECT on
2722 end-users or Apache installations. [Ken Coar]
2724 *) Integrate the mod_dav module for WebDAV protocol handling. This
2725 adds the dav and dav_fs modules, the SDBM library, and additional
2726 XML handling utilities. [Greg Stein]
2728 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2731 *) Update the lib/expat-lite/ library (bring forward changes from
2732 the Apache 1.3 repository). [Greg Stein]
2734 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2735 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2737 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2738 machines where sendfile is detected, but nobody has written ap_sendfile.
2739 [Dave Hill <ddhill@zk3.dec.com>]
2741 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2743 *) ab would start up more connections than needed, then quit when the
2744 desired number were finished. Also fixed a logic error involving
2745 ab keepalives. [Victor J. Orlikowski]
2747 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2748 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2749 timeouts (i.e, if a timeout was specified, the pipe reverted to
2750 a full blocking pipe). Now the behaviour is more in line with
2751 Unix non-blocking pipes.
2754 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2755 cache open file handles along with accept socket reuse enables
2756 Apache 2.0 to serve non-keepalive requests for static files at
2757 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2758 and Apache 2.0 will serve almost 1200 rps on my system).
2761 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2762 supports two config directives, mmapfile (same behavious as
2763 mod_mmap_static) and cachefile. Use the cachefile directive
2764 to cache open file handles. This directive only works on systems
2765 that have implemented the ap_sendfile API. cachefile works today
2766 on Windows NT, but has not been tested on any flavors of Unix.
2769 *) Cleanup the configuration. With the last few changes the
2770 configuration process automatically:
2771 inherits information about how to build from APR. Allowing
2772 APR to inform Apache that it should or should not use -ldl
2774 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2775 based on the threading model
2777 Apache calls APR's configure process before finishing it's
2778 configuration processing, allowing for more information flow
2783 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2784 with non-zero argument makes the socket non-blocking. BeOS and
2785 OS/2 already worked this way. [Jeff Trawick]
2787 *) ap_close() now calls ap_flush() for buffered files, so write
2788 operations work a whole lot better on buffered files.
2791 *) Fix error messages issued from MPMs which explain where to change
2792 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2795 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2796 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2797 now the way that the blocking state of a pipe is manipulated.
2798 ap_block_pipe() is gone. [Jeff Trawick]
2800 *) Correct the problem where the only local host name that the IP stack
2801 can discover are 'undotted' private names. If no fully qualified
2802 domain name can be identified, the default ServerName will be set to
2803 the machine's IP address string. A warning is always provided if the
2804 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2806 *) Repair problems with config file processing which caused segfault
2807 at init when virtual hosts were defined and which caused ServerName to
2808 be ignored when there was no valid DNS setup. [Jeff Trawick]
2810 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2812 *) Add ap_sendfile implementation for AIX
2813 [Victor J. Orlikowski]
2815 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2816 apr_network_io.h, and apr_thread_proc.h.
2817 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2819 *) Bring the allocation and pool debugging code back into a working
2820 state. This will need to be tested as so far it's only been used on
2823 *) Change configuration command setup to be properly typesafe when in
2824 maintainer mode. Note that this requires a compiler that can initialise
2825 unions. [Ben Laurie]
2827 *) Turn on buffering for config file reads. Part of this was to
2828 repair buffered I/O support in Unix and implement buffered
2829 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2831 *) Win32: Fix problem where UTC offset was not being set correctly
2832 in the access log. Problem reported on news group by Jerry Baker.
2835 *) Fix segfault when reporting this type of syntax error:
2836 "</container> without matching <container> section", where
2837 container is VirtualHost or Directory or whatever.
2840 *) Prevent the source code for CGIs from being revealed when using
2841 mod_vhost_alias and the CGI directory is under the document root
2842 and a user makes a request like http://www.example.com//cgi-bin/cgi
2843 as reported in <news:960999105.344321@ernani.logica.co.uk>
2846 *) Add support for the new Beos NetwOrking Environment (BONE)
2849 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2850 final input char is incomplete; ap_bwrite_xlate() now handles
2851 incomplete final input chars. [Jeff Trawick]
2853 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2854 that a bhalfduplex call occurs before logging or else DNS and
2855 such can delay the last packet of the response. [Dean Gaudet]
2857 *) Some syscall reduction in APR on unix -- don't seek when setting
2858 up an mmap; and don't fcntl() more than once per socket.
2861 *) When mod_cgid is started as root, the cgi daemon now switches
2862 to the configured User/Group (like other httpd processes)
2863 instead of continuing as root. [Jeff Trawick]
2865 *) The prefork MPM now uses an APR lock for the accept() mutex.
2866 It has not been getting a lock at all recently. httpd -V now
2867 displays APR's selection of the lock mechanism instead of the
2868 symbols previously respected by prefork. [Jeff Trawick]
2870 *) Change the mmap() feature test to check only for existence.
2871 The previous check required features not used by Apache.
2874 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2875 sometimes mangled. The len parm to accept() was not
2876 initialized, leading sometimes to an endless loop of failed
2877 accept() calls on OS/390 and anywhere else that failed the call
2878 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2879 instead of declaring it ourselves to fix a compilation problem
2880 on Solaris. [Jeff Trawick]
2882 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2884 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2886 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2888 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2889 initialization if ALLOC_DEBUG is defined; no known symptom
2890 otherwise. [Jeff Trawick]
2892 *) Fix typo in configure script when checking for mod_so. bash
2893 doesn't seem to have a problem but /bin/sh on Solaris does.
2894 Symptom: "./configure: test: unknown operator =="
2897 *) Rebind the Win32 NT and 9x services control into the MPM.
2898 All console, WinNT SCM and Win9x pseudo-service control code is
2899 now wrapped within the WinNT MPM.
2902 *) Make a copy of getenv("PATH") before storing for later use. Some
2903 getenv() implementations use the same storage for successive calls.
2904 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2906 *) Server Tokens work in 2.0 again. This also propogates the change
2907 to allow just the product name in the server string using
2911 Changes with Apache 2.0a4
2913 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2914 won't need to call it. [Greg Ames, Jeff Trawick]
2916 *) Move pre_config hook call to between configuration read and config
2917 tree walk. This allows all modules to implement pre_config hooks
2918 and know that they will be called at an appropriate time.
2921 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2924 *) Add pre-config hooks back to all modules.
2927 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2928 ContentDigest enabled and we can't/don't mmap the file.
2931 *) We now report the correct line number for syntax errors in config
2932 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2934 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2935 related bugs, and changed shmem/locking to use apr API. Shared-mem
2936 is currently disabled, however, because of problems with graceful
2937 restarts. [Ronald Tschalär]
2939 *) Fix corruption of IFS variable in --with-module= handling.
2940 Depending on the user's shell or customization thereof, there
2941 would be errors generating ap_config_auto.h later in the configure
2942 procedure. [Jeff Trawick]
2944 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2945 isn't used (as in 1.3), except that on Unix it is now logged via
2946 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2947 to the error log. [Greg Ames, Jeff Trawick]
2949 *) Add '-D' argument processing for run time configuration defines.
2952 *) Organize http_main.c as independent code, such that no code or
2953 global data is exported from it. WIN32 will dynamically link it
2954 to the server core, so this will prevent mutual dependency.
2957 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2958 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2961 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2962 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2964 *) Add mod_charset_lite for configuring character set translation.
2967 *) Add '-n' option to htpasswd to make it print its user:pw record
2968 on stdout rather than having to frob a text file. [Ken Coar]
2970 *) Fix saferead. Basically, we flush the output buffer if a read on the
2974 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2975 a conversion is single-byte only. [Jeff Trawick]
2977 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2978 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2981 *) Fix some minor errors where pid was being manipulated as an int
2982 instead of the portable pid_t. [Roy Fielding]
2984 *) Fix some error log prints that were printing the pointer to a
2985 structure rather than the pid within the structure.
2986 [Jeff Trawick, Roy Fielding]
2988 *) ab: Fix a command-line processing bug; track bad headers in
2989 err_response; support reading headers up to 2K.
2990 [Ask Bjoern Hansen <ask@valueclick.com>]
2992 *) Fix ap_resolve_env() so that it handles new function added in a prior
2993 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2994 config file.") as well as the constructs used by mod_rewrite.
2995 [Paul Reder <rederpj@raleigh.ibm.com>]
2997 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2999 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
3000 APR to perform translation, instead of accessing the hard-coded tables
3001 in 1.3's ebcdic.c. [Jeff Trawick]
3003 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
3006 *) Add the ability to hook into the config file reading phase. Basically
3007 if a directive is specified EXEC_ON_READ, then when that directive is
3008 read from the config file, the assocaited function is executed. This
3009 should only be used for those directives that must muck with HOW the
3010 server INTERPRETS the config. This should not be used for directives
3011 that re-order or replace items in the config tree. Those changes should
3012 be made in the pre-config step.
3015 *) Add mod_example to the build system.
3018 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
3019 byte character sets. [Jeff Trawick]
3021 *) Pick up various EBCDIC fixes from 1.3 (from Martin
3022 Kraemer and Oliver Reh originally according to the change log).
3025 *) Fix a couple of problems in RFC1413 support (controlled by the
3026 IdentityCheck directive). Apache did not build the request string
3027 properly and more importantly Apache would loop forever if the
3028 would-be ident server dropped the connection before sending a
3029 properly terminated response. [Jeff Trawick]
3031 *) apxs works in 2.0.
3034 *) Reliable piped logs work in 2.0.
3037 *) Introduce a hash table implementation into APR to be used for
3038 replacing tables and other random data structures in Apache.
3041 *) Add some more error reporting to htpasswd in the case of problems
3042 generating or accessing the temporary file. Also, pass in a
3043 buffer if the implementation knows how to use it (i.e., if L_tmpnam
3044 is defined). [Ken Coar]
3046 *) Configure creates config.nice now containing your configure
3047 options. Syntax: ./config.nice [--more-options]
3050 *) Fix various return code problems in APR on Win32. For most of
3051 these, APR was returning APR_EEXIST instead of GetLastError()/
3052 WSAGetLastError(). [Jeff Trawick]
3054 *) Make piped logs work again in version 2.0
3057 *) Add VPATH support to UNIX build system of Apache and APR.
3060 *) Fix ap_tokenize_to_argv to respect the const arguments that are
3064 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
3065 Patch submitted to author.
3068 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
3069 /sbin in PATH on FreeBSD (all submitted to rse previously)
3072 *) Fix building Pthread-based MPMs on OpenBSD
3073 [Sascha Schumann] PR#26
3075 *) Fix ap_readdir() problem on systems where d_name[] field in
3076 struct dirent is declared with only one byte. (This problem only
3077 affected multithreaded builds.) This caused a segfault during
3078 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3079 least). [Jeff Trawick]
3081 *) Fix some make-portability problems on at least Tru64, Irix
3083 [Sascha Schumann] PR#18, PR#39
3085 *) Add ap_sigwait() to support old-style sigwait() on systems
3086 like OS/390 and UnixWare.
3089 *) Add POSIX-thread flags for more platforms.
3092 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3093 (on Unix, at least) to handle resolver errors. Fix a bug in
3094 the definition of APR_ENOMEM so that ap_strerror() can spit
3095 out the correct error message for it.
3098 Changes with Apache 2.0a3
3100 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3103 *) API: *HOOK* macros now have an AP_ prefix
3106 *) Win32: Eliminate redundant calls to initialize winsock.
3107 [Tim Costello <timcostello@ozemail.com.au>]
3109 *) Fix bugs initializing ungetchar for pipes.
3110 [Chia-liang Kao <clkao@CirX.ORG>]
3112 *) The ab program in the src/support directory is now portable using
3116 *) Support directory is being compiled when the server is built
3119 *) The configure option --with-program-name has been added to allow
3120 developers to rename the executable at configure time. This also
3121 changes the name of the config files to match the executable's name.
3124 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3125 containing version numbers. [Martin Pool]
3127 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3128 Unix; access_log and error_log now created with these perms; non-
3129 Unix is unaffected [Jeff Trawick]
3131 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3132 Replaced more magic numbers with MD5_DIGESTSIZE.
3133 [William Rowe, Roy Fielding]
3135 *) Win32: Get mod_auth_digest compiling and added to the Windows
3136 build environment. Not tested and I'd be suprised if it
3137 actually works. [Bill Stoddard]
3139 *) Revamp the Win32 make environment. Makefiles have been removed and
3140 Apache.dsw created to bring together all the pieces. Create new file
3141 os/win32/BaseAddr.ref to define module base addresses (to prevent
3142 dll relocation at start-up).
3143 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3145 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3146 of the \015, \012, and \015\012 constants with macros.
3147 [Greg Ames <gregames@us.ibm.com>]
3149 *) Add ap_xlate_open() et al for translation of text between different
3150 character sets. The initial implementation requires iconv().
3153 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3154 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3156 *) CGI output is being timed out now.
3159 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3160 is used by the new apr file. There is no reason to create a new file
3161 with the same lifetime as the original file.
3164 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3165 module base addresses. This will help shooting seg faults
3166 in the field. [William Rowe <wrowe@lnd.com>]
3168 *) Update Apache on Windows documentation. Add new document
3169 describing how to compile Apache on Windows.
3170 [William Rowe <wrowe@lnd.com>]
3172 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3173 microseconds instead of seconds. Some storage leaks and other
3174 minor bugs in related code were fixed. [Jeff Trawick]
3176 *) Win32: First cut at getting mod_isapi working under 2.0
3177 [William Rowe <wrowe@lnd.com>]
3179 *) First stab at getting mod_auth_digest working under 2.0
3180 quick change summary:
3181 - moved the random byte generation (ap_generate_random_bytes) into APR
3182 - now uses ap_time_t
3183 - compiles and runs on linux
3185 [Brian Martin <bmartin@penguincomputing.com>]
3187 *) Win32: Move the space stripping of physical service names
3188 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3189 unresolved symbol. Add dependency checking to the
3190 CreateService call to ensure TCPIP and AFP (winsock) is started
3192 [William Rowe <wrowe@lnd.com>]
3194 *) Win32: Add code to perform latebinding on functions that may
3195 not exist on all levels of Windows where Apache runs. This
3196 is needed to allow Apache to start-up on Win95/98. All calls
3197 to non portable functions should be protected with
3198 ap_oslevel checks to prevent runtime segfaults.
3199 [William Rowe <wrowe@lnd.com>]
3201 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3203 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3205 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3206 This addresses PR 1623. Still need to address timing out runaway
3207 CGI scripts. [Bill Stoddard]
3209 *) Win32: Make ap_stat Windows 95/98 friendly
3210 [William Rowe <wrowe@lnd.com>]
3212 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3213 always fail. Need to initialise the dwOSVersionInfoSize member of the
3214 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3217 The patch also enhances ap_get_oslevel (and the associated enum) to
3218 handle selected service packs for NT4, and adds recognition for
3219 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3220 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3221 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3223 *) Get mod_rewrite building and running, and mod_status building for Win NT
3224 [Allan Edwards <ake@raleigh.ibm.com>]
3226 *) Patch to port mod_auth_db to the 2.0 api and also to support
3227 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3228 2.7.7. It should work with version 1 as well but I haven't tested it.
3229 [Brian Martin <bmartin@penguincomputing.com>]
3231 *) Get APR DSO code working under Windows. Includes cross platform
3233 [Tim.Costello@BTFinancialgroup.com]
3235 *) Fix some of the Windows APR time functions.
3238 *) FAQ changes related to tidying up historical documents on the web site.
3239 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3241 *) Move Windows DSO code into APR.
3244 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3245 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3246 at build time. At this point, the server will not compile on Windows because
3247 of the recent DSO commits. Fixing those next.
3248 [Bill Rowe & Bill Stoddard]
3250 *) Added error checking for file I/O APR routines.
3251 [Jon Travis <jtravis@covalent.net>]
3253 *) APR: Don't use the values of resolver error codes for the
3254 corresponding APR error codes. On Unix and Win32, return the
3255 proper APR error code after a resolver error. [Jeff Trawick]
3257 Changes with Apache 2.0a2
3259 *) Renamed the executable back to httpd on all platforms other
3263 *) Allow BeOS to survive restarts, log properly and a few
3264 small things it had problems with due to the way it setup
3265 users and groups. [David Reid]
3267 *) Get mod_rewrite working with APR locks
3268 [Paul Reder <rederpj@raleigh.ibm.com>]
3270 *) Actually remove the sempahore when the lock cleanup routine
3271 is called on BeOS. [David Reid]
3273 *) Clear hook registrations between reads of the config file.
3274 When DSOs are unloaded and re-loaded the old hook pointers may
3275 no longer be valid. This fix eliminates potential segfaults.
3276 [Allan Edwards <ake@raleigh.ibm.com>]
3278 *) Fix a problem with Sigfunc not being defined or bypassed
3279 if sigaction() wasn't found. [Jim Jagielski]
3281 *) Fix the locking mechanism on BSD variants. They now use fcntl
3282 locks. This allows the server to start and serve pages.
3285 *) First cut at getting the Win32 installer to work
3286 [William Rowe <wrowe@lnd.com>]
3288 *) Get htpasswd compiling under Windows
3289 [William Rowe <wrowe@lnd.com>]
3291 *) Change the log message for a bind() failure to show the
3292 interface and port number. [Jeff Trawick]
3294 *) Import the documentation from 1.3.12 and bring parts of it
3295 up-to-date with respect to the changes that have occurred
3299 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3300 now logged correctly on BeOS.
3303 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3304 Makefile.win includes the same user interface as the old
3306 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3308 *) Win32 exec now uses COMSPEC environment string for command
3309 shell path resolution.
3310 [William Rowe <wrowe@lnd.com>] PR#3715
3312 *) Win32: ap_connect() was not returning correct error condition
3314 [Allen Prescott <allen@clanprescott.com>]
3316 *) Win32: ap_open() was broken on Win9x because an NT-specific
3317 flag was passed to CreateFile. ap_puts() added an unnecessary
3319 [Jeff Trawick <trawick@us.ibm.com>]
3321 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3322 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3323 confusing ee/et name and made all extensions language/dialect
3324 rather than country reflecting. Changed example files to
3325 explicit reflect the ISO charset and added a few common
3326 ones to the example config [dirkx]
3328 *) Extend external module capability. To use this, you call
3329 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3332 *) Backported the various "default charset" fixes from 1.3.12,
3333 including the AddDefaultCharset directive. [Jim Jagielski]
3335 *) Added the capability to do ${ENVVAR} constructs in the
3336 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3337 it does this on a line by line basis; i.e. if the envvar
3338 expands to something with spaces you have to protect it
3339 by adding quotes around it (Unless of course you expect it
3340 to contains more than one argument. Alternatively you
3341 can compile it on a per token basis; which is what people
3342 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3343 hampers fancier hacks.
3344 [Dirk-Willem van Gulik]
3346 *) Changed the 'ErrorDocument' syntax in that it NO longer
3347 supports the asymetric
3349 ErrorDocument 301 "Some message
3351 Note the opening " quote, without a closing quote. It now
3352 has either the following syntaxes
3354 ErrorDocument XXX /local/uri
3355 ErrorDocument XXX http://valid/url
3356 ErrorDocument XXX "Some Message"
3358 The recognition heuristic is: if it has a space it
3359 is a message. If it has no spaces and starts with a /
3360 or is a valid URL then treat it that way. Otherwise it
3361 is assumed to be a message.
3363 This breaks backward compatibility but makes live a hell
3364 of a lot easier for GUI's and config file parsers.
3365 [Dirk-Willem van Gulik]
3367 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3368 syntax into a 'on' or 'off' syntax. As it currently is the
3369 only non nesting token which uses NO_ARGS and thus is an
3370 absolute pain for any config interface automation. This
3371 breaks backward compatibility. [Dirk-Willem van Gulik]
3373 *) Add ability to add external modules to the build process. This is
3374 done with --with-module=/path/to/module. Modules can only be added
3375 as static modules at this point.
3378 Changes with Apache 2.0a1
3380 *) Fix FreeBSD 3.3 core dump.
3381 Basically, ap_initialize() needs to get called before
3382 create_process(), since create_process() passes op_on structure
3383 to semop() to get a lock, but op_on isn't initialized until
3384 ap_initialize() calls setup_lock(). Here is a slight
3385 rearrangement to main() which calls ap_initialize() earlier...
3386 [Jeff Trawick <trawick@us.ibm.com>]
3388 *) Enable Apache to use sendfile/TransmitFile API
3389 [Bill Stoddard, David Reid, Paul Reder]
3391 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3395 *) Make file I/O and network I/O writev/sendv APIs consistent.
3396 Eliminate use of ap_iovec_t and use Posix struct iovec.
3397 Use seperate variable on ap_writev to set the number of iovecs
3398 passed in and number of bytes written.
3401 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3402 with ap_create_file_iol(). ap_create_file_iol() requires that
3403 the file be opened prior to the call using ap_open().
3406 *) Port mod_include and mod_cgi to 2.0
3407 [Paul Reder, Bill Stoddard]
3409 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3410 bytes_read/bytes_written is always valid (never -1). Plus
3411 some fixes to buff.c to correct problems introduced by the
3412 errno => ap_status_t changes a while back. Plus a fix to
3413 chunked encoding introduced right at the beginning of 2.0.
3416 *) Revamped UNIX build system to use autoconf and libtool.
3417 [Manoj Kasichainula, Sascha Schumann]
3419 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3421 *) More rigorous checking of Host: headers to fix security problems
3422 with mass name-based virtual hosting (whether using mod_rewrite
3423 or mod_vhost_alias).
3424 [Ben Hyde, Tony Finch]
3426 *) Add back support for UseCanonicalName in <Directory> containers.
3427 [Manoj Kasichainula]
3429 *) Added APLOG_STARTUP log type. This allows us to write an error
3430 message without any of the date and time information. As a part
3431 of this change, I also removed all of the calls to fprintf(stderr
3432 and replaced them with calls to ap_log_error using APLOG_STARTUP
3433 writing to stderr is no longer portable, because we don't direct
3434 stderr to the error log on all platforms.
3437 *) Convert error logging functions to take errno as an argument.
3438 This makes our error logs more portable, because some Windows API's
3439 don't set errno. This change allows us to still output a valid
3440 message on all of our platforms.
3443 *) mod_mime_magic runs in 2.0-dev now.
3444 [Paul Reder <rederpj@raleigh.ibm.com>]
3446 *) sendfile has been added to APR.
3447 [John Zedlewski <zedlwski@Princeton.EDU>]
3449 *) buff.c has been converted to no longer use errno.
3450 [Manoj Kasichainula]
3452 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3453 interface adaption to APR functions did it. [Martin Kraemer]
3455 *) Support DSOs properly on 32-bit HP-UX 11.0
3456 [Dilip Khandekar <dilip@cup.hp.com>]
3458 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3459 [Ralf S. Engelschall]
3461 *) Cleaned APR build environment integration and bootstrap APR
3462 automatically for developers from src/Configure.
3463 [Ralf S. Engelschall]
3465 *) Fixed building of src/support/htpasswd.c
3466 [Ralf S. Engelschall]
3468 *) When generating the Location: header, mod_speling forgot
3469 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3472 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3474 *) Change all pools to APR contexts. This is the first step to
3475 incorporating APR into Apache. [Ryan Bloom]
3477 *) Move "handler not found" warning message to below the check
3478 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3479 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3481 *) Support line-continuation feature in config.option file and
3482 allow the loading of multiple option sections at once via
3483 ``--with-option=<section1>,<section2>,...''
3484 [Ralf S. Engelschall]
3486 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3488 Changes with Apache MPM
3490 *) Use asynchronous AcceptEx() and a completion port to accept and
3491 dispatch connections to threads in Windows NT/2000.
3494 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3497 *) Implement the APACI --with-option facility
3498 (per default used the config.option file).
3499 [Ralf S. Engelschall]
3501 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3503 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3504 Replace pre_connection module call with a register_hook call and
3505 implement pre_connection as a hook. The intent is that these hooks will
3506 be extended to allow Apache to be multi-protocol, and also to allow the
3507 calling order to be specified on a per-hook/per-module basis.
3510 *) Implement mpm_* methods as "modules". Each method gets its own
3511 subdir in src/modules (eg: src/modules/prefork). Selection
3512 of method uses Rule MPM_METHOD. [Jim Jagielski]
3514 *) Port the hybrid server from the apache-apr repository as
3515 mpm_mpmt_pthread. [Manoj Kasichainula]
3517 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3518 amongst the unix MPMs.
3520 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3521 signal handling for the new world order. [Dean Gaudet]
3523 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3524 of alloc.c for now. [Dean Gaudet]
3526 *) Handle partial large writes correctly. [Ben Laurie]
3528 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3529 based on IP/port. [Ben Laurie]
3531 *) Port a bunch of modules to the new module structure.
3532 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3534 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3536 *) Basic restructuring to introduce the MPM concept; includes various
3537 changes to the module API... better described by
3538 docs/initial_blurb.txt. [Dean Gaudet]
3540 Changes with Apache pthreads
3542 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3543 buff operations (generally over a network).
3544 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3546 *) Created http_accept abstraction. Added 4 new functions (not exported):
3547 init_accept(), begin_accepting_requests(), get_request(),
3548 stop_accepting_requests() [Bill Stoddard]
3550 *) Fix to ap_rprintf call that allows mod_info to work properly.
3551 [James Morris <jmorris@intercode.com.au>]
3553 *) user and ap_auth_type fields were moved from connection_rec to
3554 request_rec. [Ryan Bloom]
3556 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3557 needed in a threaded server.
3559 *) Initial pthread implementation from from Dean's apache-nspr code.
3560 [Bill Stoddard, Ryan Bloom]
3563 Changes with Apache 1.3.9
3565 *) Remove bogus error message when a redirect doesn't set Location.
3566 Instead, use an empty string to avoid coredump if the error message
3567 was supposed to include a location. [Roy Fielding]
3569 *) Don't allow configure to include mod_auth_digest unless it is
3570 explicitly requested, even if the user asked for all modules.
3573 *) Translate module names to dll names for OS/2 so that they are no more
3574 than 8 characters long and have an extension of "dll" instead of "so".
3577 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3578 Fix test-compile check to check for randbyte instead of trand32.
3579 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3580 and tweak to make Amaya happier. [Ronald Tschalär]
3582 *) Ensure that the installed expat include files are world readable,
3583 just like the other header files. [Martin Kraemer]
3585 *) Fixed generated AddModule adjustments in APACI's `configure' script
3586 in order to allow (new) modules like mod_vhost_alias to be handled
3587 correctly (which was touched by the adjustments for mod_alias).
3588 [Ralf S. Engelschall]
3590 *) For binary builds, add -R flag to apachectl to work around the lack of
3591 an absolute path to the ./libexec directory where the libhttp.ep file
3592 is needed for SHARED_CORE architectures. [Randy Terbush]
3594 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3595 problem observed by some Win95/98 users where they get CGI script
3596 output sent to the console. [Bill Stoddard]
3598 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3599 routines are now called ap_base64* and are 'plain' (i.e., no
3600 pool access or anything clever). Inside util.c the routines acting
3601 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3602 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3603 now but deprecated. [dirkx]
3605 *) Clean up the base64 and SHA1 additions and make sure they are
3606 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3607 files. [Roy Fielding]
3609 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3610 checking. Allow compiling on VS 6.0. [Randy Terbush]
3612 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3614 *) Use TestCompile to search for the truerand library (rather than blindly
3615 assuming its existence). If it is not found, complain (but do not
3616 exit - yet). [Martin Kraemer]
3618 *) We forgot to add the new exported function names to
3619 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3621 *) Add description of -T command-line option to usage().
3622 [Ralf S. Engelschall]
3624 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3625 searched only AFTER libap has been searched, because libap needs
3626 some symbols from libos. [Martin Kraemer]
3628 *) Fix conflict with original mod_digest related to the symbol of the
3629 module dispatch list (which has to be unique for DSO and follow the
3630 usual conventions for the installation procedure).
3631 [Ralf S. Engelschall]
3633 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3634 for other platforms as well. [Martin Kraemer]
3636 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3637 types by AP_LONG and replace reference to renamed variable 'ubuf'
3638 by 'buffer'. [Martin Kraemer]
3640 Changes with Apache 1.3.8 [not released]
3642 *) Flush the output buffer immediately after sending an error or redirect
3643 response, since the result may be needed by the client to abort a
3644 long data transfer or restart a series of pipelined requests.
3645 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3647 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3648 [Ian Turner <iant@sequent.com>] PR#4735
3650 *) Local struct mmap in http_core.c conflicted with system structure
3651 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3653 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3654 [Ronald Tschalär <ronald@innovation.ch>]
3656 *) Fix a memory leak where the module counts were getting messed
3657 up across restarts. [David Harris <dharris@drh.net>]
3659 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3660 properly in mod_access.
3661 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3663 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3664 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3666 *) PORT: Support for compaq/tandem/com.
3667 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3669 *) Added SHA1 password encryption support to easy migration from
3670 Netscape servers. See support/SHA1 for more information.
3671 Caused the separation of ap_md5.c into md5, sha1 and a general
3672 ap_checkpass.c with just a validate_passwd routine. Added a
3673 couple of flags to support/htpasswd. Some reuse of the to64()
3674 function; hence renamed to ap_to64().
3675 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3677 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3678 with ASCII/EBCDIC conversions in "ident" query.
3679 [David McCreedy <McCreedy@us.ibm.com>]
3681 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3682 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3683 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3685 *) Fix SIGSEGV on some systems because the Vary fix below included
3686 a call to table_do with a variable argument list that was not
3687 NULL terminated. Replaced with better implementation. [Roy Fielding]
3689 Changes with Apache 1.3.7 [not released]
3691 *) The "Vary" response header field is now sanitised right before
3692 the header is sent back to the client. Multiple "Vary" fields
3693 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3694 "Vary: host, negotiate, host, accept-language") are reduced to
3695 single instances. This is a better solution than the force-no-vary
3696 one (which is still valid for clients that can't cope with Vary
3697 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3699 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3701 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3702 least on Linux and FreeBSD for now.
3705 *) Win32: More apache -k restart work. Restarts are now honored
3706 immediately and connections in the listen queue are -not- lost.
3707 This is made possible by the use of the WSADuplicateSocket()
3708 call. The listeners are opened in the parent, duplicated, then
3709 the duplicates are passed to the child. The original listen sockets
3710 are not closed by the parent across a restart, thus the listen queue
3712 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3714 *) Fix handling of case when a client has sent "Expect: 100-continue"
3715 and we are going to respond with an error, but get stuck waiting to
3716 discard the body in the pointless hope of preserving the connection.
3717 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3719 *) Fix 'configure' to work correctly with SysV-based versions of
3720 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3722 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3723 built-in values. Add "-e" option which works like -i but doesn't
3724 install the DSO; useful for editing httpd.conf with apxs. Fix
3725 editing code so that multiple invocations of apxs -a will not
3726 create duplicate LoadModule/AddModule entries; apxs can now be
3727 used to re- enable/disable a module. [Wilfredo Sanchez]
3729 *) Win32: Update the server to use Winsock 2. Specifically, link with
3730 ws2_32.lib rather than wsock32.lib. This gives us access to
3731 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3732 Win 95 users may need to update their TCP/IP stack to pick up
3733 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3734 [Bill Stoddard stoddard@raleigh.ibm.com]
3736 *) Win32: Redirect CGI script stderr (script debug info) into the
3737 error.log when CGI scripts fail. This makes Apache on Win32
3738 behave more like Unix.
3739 [Bill Stoddard stoddard@raleigh.ibm.com]
3741 *) Fixed `httpd' usage display: -D was missing.
3742 [Ralf S. Engelschall] PR#4614
3744 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3745 [Ralf S. Engelschall] PR#4561, PR#4562
3747 *) OS/2: Fix problem with accept lock semaphores where server would die with
3748 "OS2SEM: Error 105 getting accept lock. Exiting!"
3749 [Brian Havard] PR#4505
3751 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3752 [Randy Terbush <randy@covalent.net>]
3754 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3755 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3757 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3758 command potentially _is_ GCC. [Ralf S. Engelschall]
3760 *) Fix apxs build issues on AIX
3761 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3763 *) DocumentRoot Checking: Under previous versions, when Apache
3764 first started up, it used to do a stat of each DocumentRoot to
3765 see if it existed and was a directory. If not, then an error
3766 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3767 does not exist, you will get error messages in error_log. If
3768 the '-t' command line option is used (to check the configuration)
3769 the check of DocumentRoot IS performed. An additional command
3770 line option, '-T', has been added if you want to avoid the
3771 DocumentRoot check even when checking the configuration.
3774 *) Win32: The query switch "apache -S" didn't exit after showing the
3775 vhost settings. That was inconsistent with the other query functions.
3776 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3778 *) Win32: Changed behaviour of apache -k restart.
3779 Previously, the server would drain all connections in the stack's
3780 listen queue before honoring the restart. On a busy server, this
3781 could take hours. Now, a restart is honored almost immediately.
3782 All connections in Apache's queues are handled but connections in
3783 the stack's listen queue are discarded. Restart triggered by
3784 MaxRequestPerChild is unchanged.
3785 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3787 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3788 the accept loop. Good for a 5% performance boost. Cleaned up
3789 parent/child process management code.
3790 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3792 *) Added ceiling on file size for memory mapped files.
3793 [John Giannandrea <jg@meer.net>] PR#4122
3795 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3796 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3797 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3799 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3800 use this at least for Expat. [Ralf S. Engelschall]
3802 *) Allow .module files to specify libraries with Lib:.
3805 *) Allow SetEnvIf[NoCase] to test environment variables as well
3806 as header fields and request attributes. [Ken Coar]
3808 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3809 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3811 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3812 never accepted into any standard, and it opens up certain DoS
3813 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3815 *) TestCompile updated. We can now run programs and output the
3816 results during the Configure process. [ Jim Jagielski]
3818 *) The source is now quad (long long) aware as needed. Specifically,
3819 the Configure process determines the correct size of off_t and
3820 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3821 provides for the 'q' format qualifier (if quads are not available,
3822 'q' is silently "demoted" to long). [Jim Jagielski]
3824 *) When the username or password fed to htpasswd is too long, include the
3825 size limit in the error message. Also report illegal characters
3826 (currently only ':') in the username. Add the size restrictions
3827 to the man page. [Ken Coar]
3829 *) Fixed the configure --without-support option so it doesn't result in
3830 an infinite loop. [Marc Slemko]
3832 *) Piped error logs could cause a segfault if an error occured
3833 during configuration after a restart.
3834 [Aidan Cully <aidan@panix.com>] PR#4456
3836 *) If a "Location" field was stored in r->err_headers_out rather
3837 than r->headers_out, redirect processing wouldn't find it and
3838 the server would core dump on ap_escape_html(NULL). Check both
3839 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3840 if Location isn't set. [Doug MacEachern, Ken Coar]
3842 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3843 of the Expat 1.0.2 distribution. [Greg Stein]
3845 *) Replace regexec() calls with calls to a new API stub function
3846 ap_regexec(). This solves problems with DSO modules which use the regex
3847 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3849 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3850 environment variables can be set according to the protocol version
3851 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3853 *) Add DSO support for OpenStep (Mach 4.2) platform.
3854 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3856 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3857 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3859 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3860 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3862 *) Better DSO flags recognition on NetBSD platforms using ELF.
3863 [Todd Vierling <tv@pobox.com>] PR#4310
3865 *) Always log months in english format for %t in mod_log_config.
3866 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3868 *) Support for server-parsed and multiview-determined ReadmeName and
3869 HeaderName files in mod_autoindex. Removed the restriction on
3870 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3871 routines will deal with the access issues. (It's now possible to
3872 have {site|group|project|customer|...} wide readmes and headers.)
3873 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3876 *) When stat() fails, don't assume anything about the contents of
3877 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3879 *) It's OK for a semop to return EINTR, just loop around and try
3880 again. [Dean Gaudet]
3882 *) Fix configuration engine re-entrant hangups, which solve a
3883 handful of problems seen with mod_perl <Perl> configuration sections
3884 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3886 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3887 by default when building with APACI; allow for platform-specific
3888 variable defaults in configure. [Wilfredo Sanchez]
3890 *) Do setgid() before initgroups() in http_main; some platforms
3891 zap the grouplist when setgid() is called. This was fixed in
3892 suexec earlier, but the main httpd code missed the change.
3893 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3895 *) Add recognition of .tgz as a gzipped tarchive.
3896 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3898 *) mod_include's fsize/flastmod should allow only relative paths, just
3899 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3901 *) OS/2: Add support for building loadable modules using DLLs.
3904 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3907 *) Fix minor but annoying bug with the test for Configuration.tmpl
3908 being newer than Configuration so that it is less likely to fail
3909 when using APACI and shadow sources. [Wilfredo Sanchez]
3911 *) PORT: Add initial support for Mac OS (versions 10.0 and
3912 greater). Use Mac OS X Server layout for now. Clean up dyld code
3913 in unix/os.c, and don't install the dyld error handlers, which
3914 are no longer needed in Mac OS. [Wilfredo Sanchez]
3916 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3917 locations to appropriate ones for user-built (as opposed to
3918 system) installs. [Wilfredo Sanchez]
3920 *) Modify mod_autoindex's handling of AddDescription so that the
3921 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3923 *) Add functionality to the install-bindist.sh script created by
3924 binbuild.sh to use tar when copying distribution files to the
3925 serverroot. This allows upgrading an existing installation
3926 without nesting the new distribution in the old.
3928 install-bindist.sh now detects the local perl5 path to install
3929 apxs and dbmmanage with proper path to perl interpreter.
3931 Add an install-binsupport target which copies the source files
3932 for apxs and dbmmanage to bindist to allow these scripts to
3933 be properly installed relative to the destination serverroot.
3934 [Randy Terbush, Covalent Technologies, randy@covalent.net]
3936 *) Fix intermittent SEGV in ap_proxy_cache_error() in
3937 src/modules/proxy_util.c where a NULL filepointer and

3945 *) OS/2: Fix terminating CGIs that aren't compiled by EMX GCC when a
3946 connection is aborted. [Brian Havard]
3948 *) Force the LANG envariable to the known state of "C" so that we
3949 have assurance about how string manipulators (e.g., tr) will
3950 function. [Ken Coar] PR#1630
3952 *) Add a directive to allow customising of the tracking cookie name.
3953 [Ken Coar] PR#2921, 4303
3955 *) Add "force-no-vary" envariable to allow servers to work around
3956 clients that choke on "Vary" fields in the response header.
3957 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
3959 *) Fixed a bug in mod_dir that causes a child process will infinitely
3960 recurse when it attemps to handle a request for a directory wnd the
3961 value of the DirectoryIndex directive is a single dot. Also likely
3962 to happen for anyother values of DirectoryIndex that will map back
3963 to the same directory. The handler now only considers regular files
3964 as being index candidates. No PR#s found.

3971 [Raymond S Brand <rsbx@rsbx.net>] PR#4248
3973 *) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand
3976 *) Add APACI --without-execstrip option which can be used to disable the
3977 stripping of executables on installation. This is very important for DSO
3978 and debugging situations. [Ralf S. Engelschall]
3980 *) Add support for OS/2 (case insenstive filesystem, .exe suffix, etc)
3981 to APACI files and related scripts.

3994 [Paul Sutton <paul@awe.com>]
3996 *) Make sure RewriteLock can be used only in the global context, (i.e.
3997 outside of any <VirtualHost> sections) because it's a global facility of
3998 the rewrite engine. [Ralf S. Engelschall]
4000 *) Fix the ownership delegation for proxy directory under `make install'.

4003 *) APACI would not correctly build suexec. [Maria Verina
4004 <mariav@icgeb.trieste.it>] PR#4260
4006 *) mod_mime_magic passed only the first 4k of a file to
4007 uncompress/gzip, but those tools sometimes do not produce
4008 any output unless a sufficient portion of the compressed
4009 file is input. Change to pass the entire file -- but
4010 only read 4k of output.

4040 *) Prevent clobbering saved IFS values in APACI. [Jim Jagielski]
4042 *) Fix buffer overflows in ap_uuencode and ap_uudecode pointed out
4043 by "Peter 'Luna' Altberg <peter@altberg.nu>" and PR#3422
4044 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
4046 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
4049 *) Correct an apparent typo: on the Windows and MPE platforms, the
4050 htpasswd utility was limiting passwords to only 8 characters.
4053 *) EBCDIC platforms: David submitted patches for two bugs in the
4054 MD5 digest port for EBCDIC machines:
4055 a) the htdigest utility overwrote the old contents of the digest file
4056 b) the Content-MD5 header value (ContentDigest directive) was wrong
4057 when the returned file was not converted from EBCDIC, but was a
4058 binary (e.g., image file) in the first place.
4059 [David McCreedy <mccreedy@us.ibm.com>]
4061 *) support/htpasswd now permits the password to be specified on the
4062 command line with the '-b' switch. This is useful when passwords
4063 need to be maintained by scripts -- particularly in the Win32
4064 environment. [Ken Coar]
4066 *) Win32: Win32 multiple services patch. Added capability to install and
4067 run multiple copies of apache as individual services.
4070 apache -n apache1 -i -f c:/httpd.conf
4071 Installs apache as service 'apache1' and associates c:/httpd.conf
4074 Starts apache1 service.
4076 Stops apache1 service
4079 apache -n apache2 -i
4080 Installs apache as service 'apache2'. httpd.conf is located under
4081 the default server root (/apache/conf/httpd.conf).
4083 Starts apache2 service.
4086 apache -n apache3 -i -d c:/program files/apache
4087 Install apache as service 'apache3' and sets server root to
4088 c:/program files/apache.
4091 apache -n apache2 -k restart
4092 Restart apache2 service
4094 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
4096 *) Correct the signed/unsigned character handling for the MD5 routines;
4097 mismatches were causing compilation problems with gcc -pedantic and
4098 in the TPF cross-compilation. [Ken Coar]
4100 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4101 a roughly 5 fold speed up. [Brian Havard]
4103 *) proxy ftp: instead of using the hardwired string "text/plain" as
4104 a fallback type for files served by the ftp proxy, use the
4105 ap_default_type() function to determine the configured type.
4106 This allows for special configurations like
4107 <Directory proxy:ftp://some.host>
4108 DefaultType gargle/blurb
4110 Additionally, add the Content-Encoding: header to FTP proxy replies
4111 when the encoding is defined (by the AddEncoding directive).
4112 Because it was missing, it was almost impossible to browse compressed
4113 files using the FTP proxy (works now perfectly in Communicator).
4114 The ftp proxy now also returns the Date: and Server: header lines (if not
4115 much else... This code is "somewhat" broken) like normal requests do.
4118 *) Be more smart in APACI's configure script when determining the UID/GID
4119 for User/Group directives and use the determined UID/GID to initialize
4120 the permissions on the proxycachedir.
4121 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4123 *) Changed the forking-prior-to-cleanup in the proxy module to first
4124 check wether it actually needs to collect garbage. This reduces
4125 the number of fork()s from one/request to just the odd one an hour.
4126 [Dirk-Willem van Gulik]
4128 *) Added proxy, auth and header support to src/support/ab.c. Added a
4129 README file to src/support/
4130 [Dirk-Willem van Gulik]
4132 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.

4135 *) Add support for DSO module compilation on BSD/OS 3.x.
4136 [Randy Terbush, Covalent Technologies]
4138 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
4139 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
4140 option) were substituted with $(TARGET).conf, etc. Same for other strings
4141 with dots where the dot wasn't matched as plain text.

4149 Changes with Apache 1.3.6
4151 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
4153 Changes with Apache 1.3.5 [not released]
4155 *) M_INVALID needed a value within the scope of METHODS so that unknown
4156 methods can be access controlled. [Roy Fielding] PR#3821
4158 *) Added PassAllEnv; makes server's entire environment available
4159 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4161 *) ap_uuencode() always added two trailing '='s and encoding of
4162 8 bit characters on a machine with signed char may produced
4163 incorrect results. Additionally ap_uuencode() should now
4164 work correctly on EBCDIC platforms.
4165 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4167 *) WIN32: Binary installer now runs the configuration DLL before
4168 the reboot prompt (which is only given if MSVCRT.DLL system
4169 DLL is new or updated). This should avoid the configuration
4170 directory being empty after installation. [Paul Sutton]
4171 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
4173 *) WIN32: Binary installer now creates Start menu options to start
4174 and stop Apache as a console application and to uninstall
4175 the Apache service on NT. [Paul Sutton] PR#3741
4177 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
4179 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
4180 have been reported with flock() locking (probably related to kernel
4181 version). [Dean Gaudet] PR#2723, 3531
4183 *) Using APACI, the main config file (usually httpd.conf) was
4184 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
4185 <wsanchez@apple.com>]
4187 *) PORT: AIX does not require the SHARED_CODE "hack"
4188 [Ryan Bloom <rbb@raleigh.ibm.com>]

4194 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4195 for 8-bit safeness. [Dean Gaudet]
4197 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4198 because SPARCs have a small machine-specific maximum size for the Global
4199 Offset Table which is often exceeded when compiling one of the larger
4200 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4202 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
4203 DSO/DLL section because it's a directive from mod_status and isn't
4204 available before the DLL of mod_status is loaded.
4205 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
4207 *) SECURITY: Fix a bug in the calculation of the buffer size for the line

4216 really support all future gcc versions >= 2.7 until we know more.
4217 [John Tobey <jtobey@banta-im.com>] PR#3983
4219 *) Let APACI's configure script correctly complain for unknown --enable-XXX
4220 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
4222 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
4223 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
4224 possible buffer overflows. [Ralf S. Engelschall]
4226 *) Remove no longer used non-API function ap_single_module_init().
4227 [Ralf S. Engelschall]
4229 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4232 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4233 to make platform installations easier. [Wilfredo Sanchez]
4235 *) In configure, do not append the target name to the directory path if
4236 the path already contains "apache". [Ralf S. Engelschall]
4238 *) SIGPIPE is now ignored by the server core. The request write routines
4239 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4240 correctly check for output errors and mark the connection as aborted.
4241 Replaced many direct (unchecked) calls to ap_b* routines with the
4242 analogous ap_r* calls. [Roy Fielding]
4244 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4245 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4246 Furthermore map lookups for non-existent keys are now cached as well.
4247 Additionally "txt" maps are now parsed with simple string functions
4248 instead of using ap_pregcomp(). As a side effect a bug that prevented
4249 the usage of keys containing the "," character was fixed.
4250 The changes drastically improve the performance when large rewrite maps
4252 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4254 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4255 other than GET, and const'd the definition of method in request_rec.
4258 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
4260 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4261 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4263 *) Add %V to mod_log_config, this logs the hostname according to the
4264 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4265 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4267 *) Add support for \n and \t to mod_log_config, can be used to produce
4268 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4270 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4272 *) Added informative error messages for failed munmap() and fseek() calls
4273 in http_core.c. [John Bley, Roy Fielding]
4275 *) Added some informative error messages for some failed malloc()
4276 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4278 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4279 is removed. This allows <Directory proxy:*> directives to work and
4280 prevents invalid requests from killing the process.
4281 [Brian Havard <brianh@kheldar.apana.org.au>]
4283 *) Reorganised FAQ document.
4284 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
4286 *) src/support/: The ApacheBench benchmark program was overhauled by
4287 David N. Welton: you can now have it generate an HTML TABLE, presumably
4288 for integration into other HTML sources. David updated the ab man page
4289 as well and added some missing descriptions. Thanks!
4290 [David N. Welton <davidw@prosa.it>]
4292 *) Win32: The filename validity checker now allows filenames containing
4293 characters in the range 0x80 to 0xff (for example accented characters).
4294 [Paul Sutton] PR#3890
4296 *) Added conditional logging based upon environment variables to
4297 mod_log_config. mod_log_referer and mod_log_agent
4298 are now deprecated. [Ken Coar]
4300 *) Allow apache acting as a proxy server to relay the real
4301 reason of a failure to a client rather than the "internal
4302 server error" it does currently. The general exposure mechanism
4303 can be triggered by any module by setting the "verbose-error-to"
4304 note to "*"; this allows more than just proxy errors to be exposed.
4305 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4307 *) Moved man pages for ab and apachectrl to section 8.
4308 [Wilfredo Sanchez, Roy Fielding]
4310 *) Added -S option to install.sh so that options can be passed to
4311 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4313 *) Tweak modules Makefile generated by Configure so that it handles
4314 the test case of no modules being selected. [chaz@reliant.com]
4316 *) Added a <LimitExcept method ...> sectioning directive that allows
4317 the user to assign authentication control to any HTTP method that
4318 is *not* given in the argument list; i.e., the logical negation
4319 of the <Limit> directive. This is particularly useful for controlling
4320 access on methods unknown to the Apache core, but perhaps known by
4321 some module or CGI script. [Roy Fielding, Tony Finch]
4323 *) Prevent apachectl from complaining if the PIDFILE exists but
4324 does not contain a process id, as might occur if the server is
4325 being rapidly restarted. [Wilfredo Sanchez]
4327 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4329 *) Entity tag comparisons for If-Match and If-None-Match were not being
4330 performed correctly -- weak tags might cause false positives. Also,
4331 strong comparison wasn't properly enforced in all cases.
4332 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4334 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4337 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4338 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4340 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4341 to util.c for parsing an HTTP header field value to extract the next
4342 list item, taking into account the possible presence of nested comments,
4343 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4344 insignificant whitespace and lowercases non-quoted tokens.
4345 [Roy Fielding] PR#2065
4347 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4348 code different from 500. This allows the proxy to, e.g., return
4349 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4351 *) Fix ordering of language variants for the case where the traditional
4352 negotiation algorithm is being used with multiple language variants
4353 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4355 *) Do not round the TCN quality calculation to 5 decimal places,
4356 unlike RFC 2296, because the calculation might need 12 decimal places
4357 to get the right result. [Roy Fielding]
4359 *) Remove unused code to disable transparent negotiation when
4360 negotiating on encoding only, as we now handle encoding too
4361 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4362 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4363 some debugging statements within mod_negotiation. [Koen Holtman]
4365 *) Fixed a rare memory corruption possibility in mod_dir if the index
4366 file is negotiable and no acceptable variant can be found.
4367 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4369 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4370 searching the Win32 registry for script interpreters.
4373 *) Win32: The compiled-in default filename for the error log is now
4374 error.log, which matches the default in the distributed httpd.conf.
4377 *) Win32: Any error messages from -i or -u command line options are now
4378 displayed on the console output rather than sent to the error log.
4379 Also the "Running Apache..." message is not output unless Apache is
4380 going to serve requests. [Paul Sutton]
4382 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4383 and use a private significator ('$apr1$') to mark passwords as
4384 being smashed with our own algorithm. Also abstract the password
4385 checking into a new ap_validate_password() routine. [Ken Coar]
4387 *) Win32: The filename validity checker now allows "COM" but refuses
4388 access to "COM1" through "COM4". This allows filenames such
4389 as "com.name" to be served. [Paul Sutton] PR#3769.
4391 *) BS2000: Adapt to the new ufork() system call interface which will
4392 make subtasking easier on the OSD/POSIX mainframe environment.
4395 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4396 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4398 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4399 use `.db' instead of `.pag' not only for FreeBSD, but also when
4400 the NDBM library looks like Berkeley-DB based.
4401 [Ralf S. Engelschall] PR#3773
4403 *) Add ability to handle DES or MD5 authentication passwords.
4404 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4406 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4408 *) SECURITY: Avoid some buffer overflow problems when escaping
4409 quoted strings. (This overflow was on the heap and we believe
4410 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4412 *) Let src/Configure be aware of CFLAGS options starting with plus
4413 signs as it's the case for the HP/UX compiler.
4414 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4416 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4417 and check to see if the tar we wind up with supports '-h'.
4418 [Jim Jagielski] PR#3671
4420 *) A consistent and conservative style for all shell scripts has been
4421 implemented. Basically, all shell string tests use the traditional
4422 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4423 to protect against bare null variable strings (ie: wrapping both
4424 sides with double quotes and prepending 'x'). 'x' was chosen
4425 because it's more universal and hopefully easier for old shell
4426 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4429 *) The status module now prints out both the main server generation as
4430 well as the generation of each process. Also, the vhost info is
4431 printed with '?notable'. [Jim Jagielski]
4433 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4434 and this makes its functions available to things in src/support.
4437 Changes with Apache 1.3.4
4439 *) Renamed macros status_drops_connection to ap_status_drops_connection
4440 and vestigial scan_script_header to ap_scan_script_header_err,
4441 mostly for aesthetic reasons. [Roy Fielding]
4443 *) The query switch "httpd -S" didn't exit after showing the
4444 vhost settings. That was inconsistent with the other query functions.
4447 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4448 filename to the end of the STANDARD_MODULE_STUFF. Its
4449 presence at the beginning prevented reporting of the filename
4450 for modules compiled before 1 January 1999. [Ken Coar]
4452 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4453 to detect and prevent access to special DOS device file names.
4454 [Paul Sutton, Ken Parzygnat]
4456 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4457 and Makefile_win32_debug.txt (debug build) that work on Win95.
4458 Run each of the following from the src directory:
4459 nmake /f Makefile_win32.txt # compiles normal build
4460 nmake /f Makefile_win32.txt install # compiles and installs
4461 nmake /f Makefile_win32.txt clean # removes compiled junk
4462 nmake /f Makefile_win32_debug.txt # compiles debug build
4463 nmake /f Makefile_win32_debug.txt install
4464 nmake /f Makefile_win32_debug.txt clean
4467 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4468 to build binary distributions. [Lars Eilebrecht]
4470 *) IndexOptions SuppressColumnSorting only turned off making
4471 the column headers anchors; you could still change the display
4472 order by manually adding a '?N=A' or similar query string to the
4473 URL. Now SuppressColumnSorting locks in the sort order so
4474 it can't be overridden this way. [Ken Coar]
4476 *) Added IndexOrderDefault directive to supply a default sort order
4477 for FancyIndexed directory listings. [Ken Coar] PR#1699
4479 *) Change the ap_assert macro to a variant that works on all platforms.
4480 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4482 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4483 search for an underscore on dlsym() (as it's already the case
4484 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4486 *) Small fix for mod_env.html: The module was documented as to be _not_
4487 compiled into Apache per default, although it _IS_ compiled into
4488 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4490 *) Instead of fixing a bug in the generation procedure for config.status (a
4491 backslash was missing) we remove the bug together with it's complete
4492 context because the special cases of the past can now no longer occur
4493 because of the recent magic for the --with-layout default.

4501 *) Fix installation procedure: Now that os-inline.c is actually used (a
4502 recently fixed bug prevented this) we need to also install os-include.c
4503 in addition to os.h into the PREFIX/include/ location or building of
4504 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4506 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4507 allow us to distinguish between a garbled DSO (or even a file which isn't
4508 an Apache module DSO at all) and a DSO which doesn't match the current
4509 Apache API. [Ralf S. Engelschall] PR#3152
4511 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4512 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4513 match case insensitive (this especially avoids nasty patterns like
4514 `[tT][eE][sS][tT]'). Second two additional internal map functions
4515 `escape' and `unescape' were added which can be used to escape/unescape
4516 to/from hex-encodings in URLs parts (this is especially useful in
4517 combination with map lookups).
4518 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]

4521 forgotten (because it was a macro) in the symbol renaming process.
4522 [Ralf S. Engelschall]
4524 *) Fix some inconsistencies related to the scopes of directives. The only
4525 user visible change is that the directives `UseCanonicalName' and
4526 `ContentDigest' now use the (more correct) `Options' scope instead of
4527 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4529 *) Using DSO, the Server token was being mangled. Specifically, the
4530 module's token was being added first before the Apache token. This
4531 has been fixed. [Jim Jagielski]
4533 *) Major overhaul of mod_negotiation.c, part 2.
4534 - properly handle "identity" within Accept-Encoding.
4535 - allow encoded variants in RVSA negotiation and let them appear in
4536 the Alternates field using the non-standard "encoding" tag-list.
4537 - fixed both negotiation algorithms so that an explicitly accepted
4538 encoding is preferred over no encoding if "identity" is not
4539 included within Accept-Encoding.
4540 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4541 of large substring sequences.
4542 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4545 *) Major overhaul of mod_negotiation.c, part 1.
4546 - cleanups to mod_negotiation comments and code structure
4547 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4548 support for everything in the upcoming HTTP/1.1
4549 revision (draft-ietf-http-v11-spec-rev-06.txt).
4550 - language tag matching also handles tags with more than 2
4552 - empty Accept, Accept-Language, Accept-Charset headers are
4553 processed correctly; previously an empty header would make all
4554 values acceptable instead of unacceptable.
4555 - allowed for q values in Accept-Encoding
4556 - added support for transparent content negotiation (rfc2295 and
4557 rfc2296) (though we do not implement all features in these drafts,
4558 e.g. no feature negotiation). Removed old experimental version.
4559 - implemented 'structured entity tags' for better cache correctness
4560 (structured entity tags ensure that caches which can deal with Vary
4561 will (eventually) be updated if the set of variants on the server
4563 - this involved adding a vlist_validator element to request_rec
4564 - this involved adding the ap_make_etag() function to the global API
4565 - modified guessing of charsets used by Apache negotiation algorithm
4566 to guess 'no charset' if the variant is not a text/* type
4567 - added code to sort multiviews variants into a canonical order so that
4568 negotiation results are consistent across backup/restores and mirrors
4569 - removed possibility of a type map file resolving to another type map
4570 file as its best variant

4597 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4600 *) Update APXS manual page: some -q option arguments were missing
4601 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4603 *) Cleanup the command line options: `-?' was documented to show
4604 the usage list but does it with an error because `?' is not a valid
4605 command. OTOH a lot of users expect `-h' to print such a usage list and
4606 instead are annoyed for ages by our huge unreadable list of directives.
4607 So we now changed the command line options this way:
4609 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4610 very similar to the popular linker option.
4612 Intent: while -l gives the small list of modules, -L now gives the
4613 large list of directives implemented by these modules. This is also
4614 consistent with -v (short version info) and -V (large version info).
4616 Intent: it's now the expected option ;-)
4617 The manual page was adjusted accordingly.

4620 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4621 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4623 *) Removed recently introduced bugs and disfigurements in APACI:
4624 o fixed argument line processing: using $args was broken: It was not
4625 initialized and using args="$args $apc_option" and even args="$args
4626 \"$apc_option\"" fails in the second processing round for any arguments
4627 containing whitespaces. The only correct way is to use the construct
4628 "$@" (but not possible here) or iterate _both_ times over the implicit
4629 argument line (no argument to for-loop) which is what we now use.
4630 o make --with-layout=Apache the default without creating
4631 redundancy (copying the --with-layout block in the argument parsing
4632 loop). We achieve this by using the "$@" construct together with the
4633 `set' command to prepend --with-layout=Apache to the command line in
4634 case --with-layout is not used.
4635 o fixed auto-suffix handling now that config.layout exists.
4636 Paths which are auto-suffixed are marked with a trailing plus sign in
4637 config.layout and every path now can be marked this way (not only the
4638 four paths for which we do it currently). Additionally the suffix is
4639 no longer a static one. Instead it's now `/<target>' where <target> is
4640 the argument of the --target option or per default `httpd'.
4641 o allow also tabs (and only spaces) where we match whitespaces
4642 o various fixes and cleanups related to used shell coding style
4643 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4644 o trimmed output of --help to fit into 80 columns

4669 *) Make generation of src/Configuration.apaci more robust: It failed to
4670 differenciate between modules when one module name was a postfix of
4671 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4672 just XXX (think about totally non-standard names like "apache_ssl", too).

4706 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4707 procedure of mod_rewrite: very long keys were truncated.
4708 [Ralf S. Engelschall]
4710 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4711 identifier, currently "Apache" and "GNU" are pre-defined in the file
4712 config.layout. Custom layouts are possible by using FILE:ID as the
4713 argument where the layout ID is taken from FILE.
4715 The config.layout file consists of <Layout ID>..</Layout> sections
4716 where inside those sections "path_variable: path_value" pairs can be
4717 specified. These lines are converted to path_variable='path_value'.
4719 *) Add a DefaultLanguage directive so that files missing a language
4720 extension (e.g., .fr, .de) can be labelled as being some other
4721 default language. DefaultLanguage can appear in <Directory> and
4722 <Files> containers as well as .htaccess files. [Paul Sutton]
4725 *) Fix TARGET configuration when configuring and installing using
4726 APACI configure. TARGET now defines the basename of the configuration
4727 file, startup script, manual page, etc. log_error_core() now reports

5049 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
5050 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
5051 platform to make the braindead HPUX linker happy. Notice, for the module
5052 DSOs we don't have to use this, because these are loaded manually (and
5053 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

5064 *) Make PrintPath work generically instead of having one version
5065 strictly for OS/2. [Jim Jagielski, Brian Havard]
5067 *) Fix the recently introduced C header file checking: We now use the C
5068 pre-processor pass only (and no longer the complete compiler pass) to
5069 determine whether a C header file exists or not. Because only this way
5070 we're safe against inter-header dependencies (which caused horrible
5071 portability problems). The only drawback is that we now have a CPP
5072 configuration variable which has to be determined first (we do a similar
5073 approach as GNU Autoconf does here). When all fails the user still has
5074 the possibility to override it manually via APACI or src/Configuration.
5075 As a fallback for the header check itself we can directly check the
5076 existance of the file under /usr/include, too.

5109 because our GuessOS is still unaware of Digital UNIX versions and the
5110 -msym is just to optimize the DSO statup time a little bit it's safe and
5111 best when we leave it out now. [Ralf S. Engelschall] PR#2969
5113 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
5114 functions: First all three functions no longer fail on strings containing
5115 "%" chars and second ap_log_printf() no longer does a double-formatting
5116 (instead it directly passes through the message to be formatted to the
5117 real internal formatting function). [Ralf S. Engelschall] PR#2941
5119 *) Allow "Include" directives anywhere in the server config
5120 files (but not .htaccess files). [Ken Coar] PR#2727
5122 *) The proxy was refusing to serve CONNECT requests except to
5123 port 443 (https://) and 563 (snews://). The new AllowCONNECT
5124 directive allows the configuration of the ports to which a
5125 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5127 *) mod_expires will now act on content that is not sent from a file
5128 on disk. Previously it would never add an Expires: header to
5129 any response that did not come from a file on disk; the only
5130 case where it still doesn't (and can't) add one for that type of
5131 content is if you are using a modification date based setting.

5143 *) Recognize lowercase _and_ uppercase `uname' results under

5146 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5147 a common problem of (mis-administrated?) IIS servers, make the apache
5148 proxy immune to these errors (and ignore the duplicates, but log
5149 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5151 *) The <IfModule and <IfDefine block starting directives now only
5152 allow exactly one argument. Previously, the optional negation
5153 character '!' could be separated by whitespace without a syntax
5154 error being reported, albeit defeating the IfModule functionality
5155 (enclosed directives would ALWAYS be executed). By using the
5156 stricter syntax, these hard-to-track errors can be avoided.
5159 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5160 cause the standalone FancyIndexing directive to logically OR
5161 into any existing IndexOptions settings rather than wiping
5162 them out. [Ken Coar]
5164 *) Changes in ftp proxy: make URL parsing simpler by using the
5166 + Add display of the "current directory" in cases where it's
5167 different from the supplied path (e.g., ftp://user@host/ lives
5168 in /home/user, not in /, therefore clicking on "../" in the
5169 starting directory might send us to /home/).
5170 + When ftp login fails, (esp. when a user name was part of the
5171 URL already), we now return [401 Unauthorized ] to allow the
5172 browser to pop up an authorization dialog. This makes passwords
5173 slightly less visible (they don't appear in the regular log files)
5174 and implements a functionality that other www proxy servers
5178 *) Triggered by the recent "Via:" header changes, the proxy module would
5179 dump core for replies with invalid headers (e.g., duplicate
5180 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5181 core dump is avoided. Also, broken replies are not cached.
5182 [Martin Kraemer] PR#2914
5184 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
5185 plop gmon.out profile data for each child [Doug MacEachern]

5188 config.status script to be immune against arguments with whitespaces.
5189 [Yves Arrouye <yves@apple.com>] PR#2866
5191 *) Replace the inlined information grabbing stuff for the configuration
5192 adjustment feature (no --without-confadjust) with calls to a new helper
5193 script `buildinfo.sh' which is both more flexible and already proofed to
5194 be more robust against platform differences. This mainly fixes the
5195 recently occured ``sed: command garbled: ...'' problems.

5216 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5217 5 to 10 because there are some users out there who always have 5 to 8
5218 variables in one RewriteRule and had to patch mod_rewrite.h for every
5219 release. So 15 should be now more than enough, even for them. (I never
5220 needed more than 4 in my RewriteRules ;-)
5221 [Ralf S. Engelschall]
5223 *) Make the proxy generate and understand Via: headers
5226 *) Change the proxy to use tables instead of array_headers for
5227 the header lines. [Martin Kraemer]
5229 *) Make sure the config.status file is not overridden when just
5230 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
5232 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
5233 provide a way to trace API changes that add functionality but do
5234 not create a compatibility issue for precompiled modules, etc.
5235 See include/ap_mmn.h for more details. [Randy Terbush]
5237 *) Fix suexec installation under `make install root=xxx' situation.
5238 [Ralf S. Engelschall]
5240 *) Extend the output of the -V switch to include the paths of all
5241 compiled-in configuration files, if they were overridden at
5242 compile time, for least astonishment of the user.
5245 *) When READing a request in ExtendedStatus mode, the "old"
5246 vhost, request and client information is not displayed.
5249 *) STATUS is no longer available. Full status information now
5250 run-time configurable using the ExtendedStatus directive.
5253 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5254 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5255 a function which can be used to perform bulk update operations
5256 on tables in a more efficient manner. [Dean Gaudet]
5258 *) SECURITY: Added compile-time and configurable limits for
5259 various aspects of reading a client request to avoid some simple
5260 denial of service attacks, including limits on maximum request-line
5261 size (LimitRequestLine), number of header fields (LimitRequestFields),
5262 and size of any one header field (LimitRequestFieldsize). Also added
5263 a configurable directive LimitRequestBody for limiting the size of the
5264 request message body. [Roy Fielding]

5267 STATUS not defined. [Jim Jagielski]

5280 ap_scan_script_header_err_core() [Doug MacEachern]
5282 *) The 'status' module will now show the process pid's and their
5283 state even without full STATUS accounting. [Jim Jagielski]
5285 *) Restore the client IP address to the error log messages, this
5286 was lost during the transition from 1.2 to 1.3. Add a new
5287 function ap_log_rerror() which takes a request_rec * and
5288 formats it appropriately. [Dean Gaudet] PR#2661
5290 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5291 whitespace in input lines -- including within quoted strings.
5293 but leading and trailing whitespace should continue to be
5294 stripped [Martin Kraemer]
5296 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5297 the ugly use of an env. variable and use command-line args for
5298 alternate $PATH. Make more like advanced 'type's as well.
5301 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
5302 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
5303 <alain.st-denis@ec.gc.ca>] PR#2736
5305 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
5307 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
5308 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
5309 directory was renamed to src/os/os2/ for consistency.
5310 [Brian Havard, Ralf S. Engelschall]
5312 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5313 files (here modules) against other DSO files (here shared libraries).
5314 This is done by determining a subset of LIBS which can be safely used for
5315 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5316 disabled for all platforms to avoid problems with this (experimental)
5317 rule. But we provide it now for those people how ran into problems and
5318 want to came out by forcing linking against DSOs.

5321 *) Fix suEXEC start message: Has to be of `notice' level to really get

5337 *) One more portability fix for APACI shadow tree support: Swap order of awk
5338 and sed in top-level configure script to avoid sed fails on some

5469 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
5470 TestCompile) instead of defining them manually in conf.h based on less
5471 accurate platform definitions. This way we no longer have to fiddle with
5472 OS-type and/or OS-version identifiers to discover whether a system header
5473 file exists or not. Instead we now directly check for the existence of
5474 those esoteric ones.

5478 *) mod_setenvif (BrowserMatch* and friends) will now match a missing
5479 field with "^$". [Ken Coar]
5481 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
5482 modules to load their own modules dynamically. This improves mod_perl
5483 and mod_php3 when these modules are loaded dynamically into Apache.
5486 *) Cache a proxied request in the event that the client cancels the

5514 *) The APACI libexecdir was not extended with an "apache/" subdir
5515 if the installation prefix didn't already contain "apache", but
5516 it should be because the DSO files are Apache-specific. Now
5517 libexecdir is treated the same way sysconfdir, datadir, localstatedir

5571 directory, bail out of the request with an error message. [W G Stoddard]

5574 these are treated by Win32 as if they are ".." but are not detected by

5576 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]

5593 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5594 remove some of the classical hurdles for new users when setting up
5595 Apache. This is done per default because it is useful for the average
5596 user. Package authors can use the --without-confadjust option to disable
5597 these configuration adjustments.
5598 [Ralf S. Engelschall]
5600 *) Added an EXTRA_DEPS configuration parameter which can be used
5601 to add an extra Makefile dependency for the httpd target, for instance
5602 to external third-party libraries, etc.
5603 [Ralf S. Engelschall]
5605 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5606 as <IfModule>..</IfModule> sections) which can be used to skip or process
5607 contained commands dependend of ``-D PARAMETER'' options on the command
5608 line. This can be used to achieve logical conditions like <IfDefine
5609 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5610 and thus especially can be used for conditionally loading DSO-based
5611 modules via LoadModule, etc. [Ralf S. Engelschall]

5618 truncated which forced following HTTP headers to be data in the HTTP
5619 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5622 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5623 in top-level configure script to avoid sed fails on some platforms (for
5624 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5625 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5627 *) Improve performance of directory listings (mod_autoindex) by comparing
5628 integer keys (last-modified and size) as integers rather than converting
5629 them to strings first. Also use a set of explicit byte tests rather
5630 than strcmp() to check for parent directory-ness of an entry. Oh, and
5631 make sure the parent directory (if displayed) is *always* listed first
5632 regardless of the sort key. Overall performance winnage should be good
5633 in CPU time, instruction cache, and memory usage, particularly for large
5634 directories. [Ken Coar]
5636 *) Add a tiny but useful goody to APACI's configure script: The generation
5637 of a config.status script (as GNU Autoconf does) which remembers the used
5638 configure command and hence can be used to restore the configuration by
5639 just re-running this script or for remembering the configuration between
5641 [Ralf S. Engelschall]
5643 *) Add httpd -t (test) option for running configuration syntax tests only.
5644 If something is broken it complains and exits with a return code
5645 non-equal to 0. This can be used manually by the user to check the Apache
5646 configuration after editing and is also automatically used by apachectl
5647 on (graceful) restart command to make sure Apache doesn't die on restarts
5648 because of a configuration which is now broken since the last (re)start.
5649 This way `apachectl restart' can be used inside cronjobs without having
5650 to expect Apache to be falling down. Additionally the httpd -t can be run
5651 via `apachectl configtest'.

5800 *) A few cosmetics and trivial enhancements to APXS to make the
5801 generated Makefile more user friendly. [Ralf S. Engelschall]
5803 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5804 was updated to use the normal apache error processing, thereby allowing
5805 proxy errors to be treated by ErrorDocument's as well. For this
5806 purpose, a new module-to-core communication variable "error-notes"
5807 was introduced; the proxy (and possibly other modules) communicates
5808 its error text using this variable. Its content is copied to a new
5809 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5810 The old proxy special error routine ap_proxy_log_uerror()

5818 *) Transform the configure message "You need root privileges for suEXEC"

5820 ("make") of Apache we can allow, of course. Root privileges are needed
5821 only for the installation step ("make install"). So make sure the

5889 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5891 *) The Makefiles assumed that DSO files are build via $(LD). This
5892 is broken for two reasons: First we never defined at least LD=ld
5893 somewhere to make sure this works (it was silently assumed that most Make
5894 provide a built-in LD definition - ARGL!) and second using the generic LD
5895 variable is not the truth. Instead a special variable named LD_SHLIB is
5896 reasonable because although "ld" is usually the default, the command for
5897 building DSO files can be "libtool" or even "cc" on some systems.

5900 *) Replace the AddVersionPlatform directive with ServerTokens which
5901 provides for more control over the format of the Server:

5914 - make OSDIR also automatically be relative to src/ like INCDIR
5915 - SUBDIRS is now generated in src/Makefile only and not in
5916 Makefile.config because it is a local define for this location.
5917 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5918 any Makefile but make sure that at least the "-K inline" is kept in
5920 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5921 - updated the dependencies theirself
5922 - removed not existing SHLIB variable from "clean" targets
5923 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5924 already exists and OBJS_PIC are also just plain objects and have not
5925 directly to do with "shared" things. The only difference is that they
5926 contain PIC. So OBJS_PIC is the more canonical name.
5927 - Updated the Makefile-dependency lines for OBJS_PIC
5928 - Removed the Makefile-dependency line in Configure to avoid double
5930 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5931 of xxx.lo as GNU libtool does with its PIC objects
5932 - reduce local complexity in modules Makefile.tmpl by moving the last
5933 existing target "depend" to the generation section in Configure, too.
5934 - removed the historical $(SPACER) which was used in the past together
5935 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5936 is no longer needed.
5937 - force the build and run of the gen_xxx programs under main/ as the
5938 first step before building the objects because it looks cleaner

5959 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5961 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5962 like WIN32. Before, Win32 CGI's could have had sporadic failures
5963 if a chdir call from one thread was made between another chdir call
5964 and a spawn in another thread. So, for now don't chdir for CGI scripts
5965 in WIN32. The current CGI "spec" is unclear as to whether it's
5966 necessary. Long-term fix is to either serialize the chdir/spawn combo
5967 or use WIN32 native calls to spawn a process. This temp fix was
5968 necessary to remove this as a showstopper for 1.3's release.
5971 *) Cleanup the suEXEC support in APACI and make it more safe:
5972 1. Add big fat hint in INSTALL about risks and to read the
5973 htdocs/manual/suexec.html document before using the suexec-related
5975 2. Make sure the user has at least provided one --suexec-xxxx option
5976 (specifies suEXEC parameters) in addition to --enable-suexec option.
5977 If only --enable-suexec is given APACI stops with a hint to INSTALL
5978 and htdocs/manual/suexec.html documents.
5979 3. Provide two additional --suexec-xxxx options to make the suEXEC
5980 configuration complete (especially for package maintainers who else
5981 had to patch the source tree) by providing ways to configure minimal
5982 UID/GID and safe PATH, too.
5983 [Ralf S. Engelschall]
5985 *) Cleanup of the `configure --shadow' process:
5986 - make sure the configure script creates its temporary files in the
5987 shadow tree to avoid conflicts with parallel configure runs
5988 - removed unnecessary option "-r" from "rm" call for Makefiles
5989 - make sure the configure scripts creates the shadow-wrapper Makefile
5990 only when no shadow trees already exists
5991 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5992 when no more shadow trees exists
5993 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5994 as fast (in the past it needed 70sec, now it runs just 38sec)
5995 - make sure CVS does not complain about the created files
5996 Makefille.<gnutriple> and directories src.<gnutriple>
5997 [Ralf S. Engelschall]
5999 *) Added the ap_add_version_component() API routine and the
6000 AddVersionPlatform core directive. The first allows modules to
6001 declare themselves in the Server response header field value,
6002 augmenting the SERVER_SUBVERSION define in the Configuration file
6003 with run-time settings (more useful in a loadable-module environment).
6004 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
6005 into the server version string. [Ken Coar] PR#2056
6007 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
6010 *) Emit the "Accept-Range" header for the default handler.
6011 [Brian Behlendorf] PR#1464
6013 *) Add a note to httpd.conf-dist that apache will on some systems fail
6014 to start when the Group # is set to a negative or large positive value.
6017 *) Make sure the module execution order is correct even when some modules
6018 are loaded under runtime (`LoadModule') via the DSO mechanism:
6019 1. The list of loaded modules is now a dynamically allocated one
6020 and not the original statically list from modules.c
6021 2. The loaded modules are now correctly setup by LoadModule for
6022 later use by the AddModule command.
6023 3. When the DSO mechanism for modules is used APACI's `install'
6024 target now enables all created `LoadModule' lines per default because
6025 this is both already expected by the user _and_ needed to avoid
6026 confusion with the next point and reduces the Makefile.tmpl complexity
6027 4. When the DSO mechanism for modules is used, APACI's `install'
6028 target now additionally makes sure the module list is reconstructed
6029 via a complete `ClearModuleList+AddModule...' entry.
6030 5. The support tool `apxs' now also makes sure an AddModule command
6031 is added in addition to the LoadModule command.
6032 6. The modules.c generation was extended to now contain two
6033 comments to make sure no one is confused by the confusing terminology
6034 of loading/linking (we use load=link+load & link=activate instead of
6035 the obvious load=activate & link=link :-( )
6036 This way now there is no longer a difference under execution time between
6037 statically and dynamically linked modules.
6038 [Ralf S. Engelschall]
6040 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
6041 Big Symbol Renaming. [Ralf S. Engelschall]
6043 *) Add a comment to mod_example.c showing the format of a FLAG command
6046 *) Standardized the time format in mod_status to match that of other
6047 places in the code (e.g. DATE_GMT). PR#1551
6049 *) Fix handling of %Z in timefmt strings for those platforms with no time
6050 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
6053 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
6054 feature compatible with 'UseCanonicalName off' by changing
6055 r->server->server_hostname to ap_get_server_name(). And I changed some
6056 functions which use r->server->port to use ap_get_server_port() instead,
6057 because if there's no Port directive in the config r->server->port is 0.
6060 *) get/set_module_config are trivial enough to be better off inline. Worth
6061 1.5% performance boost. [Dean Gaudet]
6063 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
6064 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
6067 *) [BS2000 security] BS2000 needs an extra authentication to initialize
6068 the task environment to the unprivileged User id. Otherwise CGI scripts
6069 would have a way to gain super user access. [Martin Kraemer]
6071 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
6072 absolute path, only log base name of logging source as is done
6073 in unix. [Martin Kraemer]
6075 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6076 the encoding type from the Accept-Encoding header (if it's there)
6077 and use it in the response, as that's probably what it'll be expecting.
6078 [Ronald.Tschalaer@psi.ch]
6080 *) Fix to mod_alias: translate_alias_redir is dealing with
6081 a URI, not a filename, so the check for drive letters for win32
6082 and emx is not necessary. [Dean Gaudet]
6084 *) WIN32: Allow .cmd as an executable extension.
6085 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
6087 *) Make Apache header files, and some variables, C++ friendly.
6088 [Michael Anderson's <mka@redes.int.com.mx>]
6090 *) Child processes can now "signal" (by exiting with a status
6091 of APEXIT_CHILDFATAL) the parent process to abort and
6092 shutdown the server if the error in the child process was
6093 fatal enough. [Jim Jagielski]
6095 *) mod_autoindex's find_itme() was sensitive to MIME type case.
6096 [Jim Jagielski] PR#2112
6098 *) Make sure the referer_log and agent_log entries in the default httpd.conf
6099 file are also adjusted for the actual relative installation paths.
6100 [Ralf S. Engelschall] PR#2175
6102 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
6104 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
6107 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6108 Additionally the checks for finding the vendor DSO library were moved
6109 from mod_so.c to Configure because first it needs $PLAT etc. and second
6110 mod_so already uses an abstraction layer and does not fiddle with the
6111 vendor functions itself.
6112 [Jens-Uwe Mager, Ralf S. Engelschall]
6114 *) PORT: Some optimization defines for NetBSD
6115 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6117 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6118 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6120 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6121 AIX variants should work fine, too. Even AIX 3.x should work). This is
6122 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6123 which we put into a os/unix/os-dso-aix.c file.
6124 [Ralf S. Engelschall]
6126 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6127 that we should use NET_SIZE_T == int but the include files force size_t.
6128 [Ralf S. Engelschall]
6130 *) Fix two bugs in select() handling in http_main.c.
6133 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6134 is unset (as it is in situations like timeouts) where it is unclear
6135 whether errno is set or not. [Martin Kraemer]
6137 *) Just having APACI's localstatedir is too general and not enough for most
6138 of the systems. 1.3b6 again required manual APACI patches by package
6139 maintainers from RedHat and FreeBSD because for their filesystem layout a
6140 little bit more flexibility in configuring the paths is needed. Hence we
6141 provide three additional configure options (--runtimedir, --logfiledir,
6142 --proxycachedir) which now can be used for more granular adjustments if
6143 --localstatedir is not enough to fit the particular needs. As a nice
6144 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6145 [Ralf S. Engelschall]
6147 *) Make the install root for "make install" in APACI's Makefile overrideable
6148 by package authors. This way we are even more friendly to package
6149 maintainers (especially Debian and RedHat) who build for the real prefix
6150 via "configure --prefix=/<real>" but use a different local prefix via
6151 "make root=/tmp/apache install" for rolling the package without bristling
6152 the target location on their system.
6153 [Ralf S. Engelschall]
6155 *) Workaround sed limitations in APACI's configure script by now
6156 substituting in chunks of 50 commands (because for instance HPUX's vendor
6157 sed has a limit of max. 98 commands)
6158 [Ralf S. Engelschall] PR#2136
6160 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
6161 [Ralf S. Engelschall] PR#2140
6163 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6164 RENAMING process because they are defined as pre-processor macros instead
6165 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6166 [Ralf S. Engelschall]
6168 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6169 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6170 [Ralf S. Engelschall] PR#2139
6172 *) Various bugfixes and cleanups for the APACI configure script:
6173 o fix IFS handling for _nested_ situation
6174 o fix Perl interpreter search: take first one found instead of last one
6175 o fix DSO consistency check
6176 o print error messages to stderr instead of stdout
6177 o add install-quiet for --shadow situation to Makefile stub
6178 o reduce complexity by avoiding sed-hacks for rule and module list loops
6179 [Ralf S. Engelschall]
6181 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6183 *) Make sure the input field separator (IFS) shell variable is explicitly
6184 initialized correctly before _every_ `for' loop and also restored after
6185 the loops. [Ralf S. Engelschall]
6187 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6188 `magic' files from an existing Apache installation. Because people often
6189 customize these for own MIME and content types.
6190 [Ralf S. Engelschall]

6195 *) Fix the path to the ScoreBoardFile in the install-config target, too.
6196 [Ralf S. Engelschall] PR#2105
6198 *) Let "configure" clear out the users parameters (provided as shell

6201 [Ralf S. Engelschall] PR#2101
6203 *) Provide backward compatibility from some old src/Configuration.tmpl
6204 parameter names to the canonical Autoconf-style shell variable names. For

6227 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6229 *) If you start apache with the -S command line option it will dump
6230 out the parsed vhost settings. This is useful for folks trying
6231 to figure out what is wrong with their vhost configuration.
6232 (Other dumps may be added in the future.) [Dean Gaudet]
6234 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6235 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6238 *) Because /usr/local/apache is the default prefix the ``configure
6239 --compat'' option no longer has to set prefix, again. This way the
6240 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6242 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6243 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6244 to avoid "discard const" warnings. [Ralf S. Engelschall]
6246 *) If a specific handler is set for a file yet the request still
6247 ends up being handled by the default handler, log an error
6248 message before handling it. This catches things such as trying
6249 to use SSIs without mod_include enabled. [Marc Slemko]
6251 *) Fix error logging for the startup case where ap_log_error() still uses
6252 stderr as the target. Now the default log level is honored here, too.
6253 [Ralf S. Engelschall]
6255 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
6256 long" errors when generating the MODULES entry for src/Makefile

6259 *) Make sure src/Configure doesn't complain about the old directory
6260 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6262 Changes with Apache 1.3b6
6264 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6266 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6267 interface via the similar but proprietary HP/UX shl_xxx-style system
6268 calls. [Ralf S. Engelschall]
6270 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6271 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6272 Make. [Ralf S. Engelschall]
6274 *) ++++ THE BIG SYMBOL RENAMING ++++
6275 To avoid symbol clashes with third-party code compiled into the server,
6276 we globally applied the prefix "ap_" to the following classes of
6278 - Apache provided general functions (e.g., ap_cpystrn)
6279 - Public API functions (e.g., palloc, bgets)
6280 - Private functions which we can't make static (because of
6281 cross-object usage) but should be (e.g., new_connection)
6282 For backward source compatibility a new header file named compat.h was
6283 created which provides defines for the old symbol names and can be used
6284 by third-party module authors.
6287 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6288 problem under SVR4 is that there is no command flag to force the linker
6289 to export the global symbols of the httpd executable therewith they are
6290 available to the DSO's. Instead of problematic hacks like creating a
6291 dummy.so file (containing dummy references to all global symbols) the
6292 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6293 Placing the Apache core code itself into a DSO library named libhttpd.so.
6294 This way the global symbols _HAVE_ to be exported and thus are available
6295 to any manually loaded DSO's under runtime. To reduce the impact to the
6296 user to null we go even further and create a stub httpd executable which
6297 automatically keeps track of the DSO library loading itself and thus
6298 hides the complete mechanism from the user. Although the generation of
6299 this DSO library is automatically triggered for platforms which
6300 essentially need it (mostly all SVR4-derivates) it can be also enabled
6301 manually via the Rule SHARED_CORE. This can be interesting in the future
6302 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6303 features like graceful upgrades, or whatever.
6304 [Ralf S. Engelschall, Martin Kraemer]
6306 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6308 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6309 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6310 conventions while "clean" removes only stuff created by "all" targets,
6311 "distclean" additionally removes the stuff from the configuration
6312 process. This way "make distclean" (hence the name) provides a fresh
6313 source tree as it was for distribution.
6314 [Ralf S. Engelschall]
6316 *) Allow top-level (APACI) Makefile to break on build errors
6317 the same way the src/ subtree Makefiles breaks on them by replacing the
6318 initial APACI sed-subdir-display-kludge with a more clean
6319 variable-passing-solution: variable SDP can optionally hold the subdir
6320 prefix which is consistently used for displaying the subdir movement.
6321 This way even the top-level Makefile can stop correctly on errors as the
6322 user expects. [Ralf S. Engelschall]
6324 *) Fixed ordering of argument checks for RewriteBase directive.
6325 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6327 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6328 indicating that a module is being compiled for dynamic loading. Also
6329 remove #define IS_MODULE from modules and add SHARED_MODULE define
6330 to the mak/dsp files. [Alexei Kosut]
6332 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6333 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6335 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6337 *) Add documentation file and src/Configuration.tmpl entry for the
6338 experimental mod_mmap_static module. Because although it is and marked as
6339 an experimental one it is distributed and thus should be documented and
6340 prepared for configuration the same way as all others modules.
6341 [Ralf S. Engelschall]
6343 *) Add query (-q) option to apxs support tool to be able to manually query
6344 specific settings from apxs. This is needed for instance when you
6345 manually want to access Apache's header files and you need to assemble
6346 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6347 [Ralf S. Engelschall]
6349 *) Now src/Configure uses a fallback strategy for the shared object support
6350 on platforms where no explicit information is available: If a Perl
6351 installation exists we ask it about its shared object support and if it's
6352 the dlopen-style one we shamelessly guess the compiler and linker flags
6353 for creating shared objects from Perls knowledge. Of course, the user is
6354 warning about what we are doing and informed that he should send us
6355 the guessed flags when they work. [Ralf S. Engelschall]
6357 *) Provide APACI --without-support option to be able to disable the build
6358 and installation of the support tools from the src/support/ area.
6359 Although its useful to have these installed per default we should provide
6360 a way to compile and install without them for backward-compatibility.
6361 [Ralf S. Engelschall]
6363 *) Add of the new APache eXtenSion (apxs) support tool for building and
6364 installing modules into an _already installed_ Apache package through the
6365 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6366 this approach actually doesn't need the Apache source tree. The
6367 (APACI-installed) server package is enough, because this now includes the
6368 Apache C header files (PREFIX/include) and the new APXS tool
6369 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6370 module authors to build their Apache modules _OUTSIDE_ the Apache source
6371 tree while avoiding them to fiddle around with the totally platform
6372 dependend way of compiling DSO files. The tool supports all ranges of
6373 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6374 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6375 on-the-fly generate a minimalistic Makefile and sample module for the
6376 first step to provide both a quick success event and to demonstrate the
6377 APXS mechanism to module authors. [Ralf S. Engelschall]
6379 *) Fix core dumps in use of CONNECT in proxy.
6380 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6382 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6383 so that users have examples of how CustomLog can be used.
6386 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6387 the Apache distribution tree. Until Apache 1.3 there was no real
6388 out-of-the-box batch-capable build and installation procedure for the
6389 complete Apache package. This is now provided by a top-level "configure"
6390 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6391 to provide a GNU Autoconf-style frontend which is capable to both drive
6392 the old src/Configure stuff in batch and additionally installs the
6393 package with a GNU-conforming directory layout. Any options from the old
6394 configuration scheme are available plus a lot of new options for flexibly
6395 customizing Apache. [Ralf S. Engelschall]
6397 *) The floating point ap_snprintf code wasn't threadsafe.
6398 Had to remove the HAVE_CVT macro in order to do threadsafe
6399 calling of the ?cvt() floating point routines. [Dean Gaudet]
6401 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962

6406 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6407 Configure knows which CC we are using. [Jim Jagielski]
6409 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6410 was defined in a parent directory. [Lars Eilebrecht]
6412 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6413 a generic printf-style routine that can call arbitrary output
6414 routines. Use this to replace http_bprintf.c. Add new routines
6415 psprintf(), pvsprintf() which allocate the exact amount of memory
6416 required for a string from a pool. Use psprintf() to clean up
6417 various bits of code which used ap_snprintf()/pstrdup().
6420 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6421 ap_snprintf() has different semantics and formatting codes than
6422 snprintf(). [Dean Gaudet]
6424 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6425 is necessary on at least Solaris where the /etc/rc?.d scripts
6426 are run with these signals ignored, and "SIG_IGN" settings are
6427 maintained across exec().

6439 better code. [Dean Gaudet]
6441 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
6442 be a signed bitfield. So mark a few bitfields as signed to

6446 was a problem and it wasn't taking effect. [Dean Gaudet]
6448 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
6451 *) After a SIGHUP the listening sockets in the parent weren't
6452 properly marked for closure on fork().
6453 [Jürgen Keil <jk@tools.de>] PR#2000
6455 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6456 therefore not exposed to %2F -> '/' translations and 2) the request
6457 is a proxy request, so we're not dealing with a local resource anyway.
6458 Without this, the proxy would fail to work for any URL's with
6459 %2f in them (occurs quite often in
6460 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6462 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]

6465 the direct combination of `-c' & `-o' which is not honored by some
6466 compilers like UnixWare's cc. [Ralf S. Engelschall]
6468 *) WIN32: the proxy was creating filenames missing the last four

6474 code) from the already used FTP SIZE command to setup the Content-Length
6475 header if available. [Ralf S. Engelschall] PR#1183
6477 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6478 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6479 name was really too generic, added documentation for this directive to
6480 the mod_proxy.html and corrected the hyperlink to it in the
6481 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348

6484 faster [Martin Kraemer]
6486 *) Make Configure die when you give it an unknown command switch.
6489 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6490 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6491 and per default compiled support programs have manual pages - just to
6492 document our stuff a little bit more and to be able to do really
6493 Unix-like installations ;-) [Ralf S. Engelschall]
6495 *) Major cleanups to the Configure script to make it and its generated
6496 Makefiles again readable and maintainable: add SRCDIR option, removed
6497 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6498 generated sections, consequently added Makefile headers with inheritance
6499 information, added subdir movement messages for easier following where
6500 the build process currently stays (more verbose then standard Make, less
6501 verbose than GNU make), same style to comments in the Configure script,
6502 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6504 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6505 from the ZeusBench benchmarking program and can be used to determine the
6506 response performance of an Apache installation. This version is
6507 officially licensed with Zeus Technology, Ltd. See the license agreement

6509 [Ralf S. Engelschall]
6511 *) API: Various core functions that are definately not part of the API
6512 have been made static, and a few have been marked API_EXPORT. Still
6513 more have been marked CORE_EXPORT and are not intended for general
6514 use by modules. [Doug MacEachern, Dean Gaudet]
6516 *) mod_proxy was not clearing the Proxy-Connection header from
6517 requests; now it does. This did not violate any spec, however
6518 causes poor interactions when you are talking to remote proxies.

6527 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6529 *) Clean up some undocumented behavior of mod_setenvif related to
6530 "merging" two SetEnvIf directives when they match the same header
6531 and regex. Document that mod_setenvif will perform comparisons in
6532 the order they appear in the config file. Optimize mod_setenvif by
6533 doing more work at config time rather than at runtime.
6536 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6537 to allow for modules to overrule them and to reduce redefinition
6538 warnings [Jim Jagielski]
6540 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6543 *) Making the hard-coded cross-module function call mime_find_ct() (from
6544 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6545 checking is really called even for proxy requests except for URLs with
6546 HTTP schemes (because there we can optimize by not running the type
6547 checking hooks due to the fact that the proxy gets the MIME Content-type
6548 from the remote host later). This change cleans up mod_mime by removing
6549 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6550 especially unbundles mod_proxy and mod_mime. This way they both now can
6551 be compiled as shared objects and are no longer tied together.
6552 [Ralf S. Engelschall]
6554 *) util.c cleanup and speedup. [Dean Gaudet]
6556 *) API: Clarification, pstrndup() will always copy n bytes of the source
6557 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6559 *) Mark module command_rec and handler_rec structures const so that they
6560 end up in the read-only data section (and are friendlier to systems
6561 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6563 *) Add check to the "Port" directive to make sure the specified
6564 port is in the appropriate range. [Ben Hyde]
6566 *) Performance improvements to invoke_handler().
6567 [Dmitry Khrustalev <dima@bog.msu.su>]
6569 *) Added support for building shared objects even for library-style modules
6570 (which are built from more than one object file). This now provides the
6571 ability to build mod_proxy as a shared object module. Additionally
6572 modules like mod_example are now also supported for shared object
6573 building because the generated Makefiles now no longer assume there is at
6574 least one statically linked module. [Ralf S. Engelschall]
6576 *) API: Clarify usage of content_type, handler, content_encoding,
6577 content_language and content_languages fields in request_rec. They
6578 must always be lowercased; and the strings pointed to shouldn't
6579 be modified (you must copy them to modify them). Fix a few bugs
6580 related to this. [Dean Gaudet]
6582 *) API: Clarification: except for RAW_ARGS, all command handlers can
6583 treat the char * parameters as permanent, and modifiable. There
6584 is no need to pstrdup() them. Clean up some needless pstrdup().
6587 *) Now mod_so keeps track of which module shared objects with which names
6588 are loaded and thus avoids multiple loading and unloading and irritating
6589 error_log messages. [Ralf S. Engelschall]
6591 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6592 environment variable in the apache core. But that tweaking interferes
6593 with mod_setenv. So don't tweak if the user has specified an explicit
6594 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6596 *) rputs() did not calculate r->sent_bodyct properly.
6597 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6599 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6600 name, or left unset if this value is unavailable. Apache was setting
6601 it to the IP address when unavailable.
6602 [Tony Finch <fanf@demon.net>] PR#1925
6604 *) Various improvements to the configuration and build support for compiling
6605 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6606 OSF1 support with GCC and vendor compilers was added. This way shared
6607 object support is now provided out-of-the-box for FreeBSD, Linux,
6608 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6609 [Ralf S. Engelschall]
6611 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6612 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6613 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6615 *) Fix one more special locking problem for RewriteMap programs in
6616 mod_rewrite: According to the documentation of flock(), "Locks are on
6617 files, not file descriptors. That is, file descriptors duplicated
6618 through dup(2) or fork(2) do not result in multiple instances of a lock,
6619 but rather multiple references to a single lock. If a process holding a
6620 lock on a file forks and the child explicitly unlocks the file, the
6621 parent will lose its lock.". To overcome this we have to make sure the
6622 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6623 the case by opening it in the child_init instead of the module_init API
6624 hook. [Ralf S. Engelschall] PR#1029
6626 *) Change to Location and LocationMatch semantics. LocationMatch no
6627 longer lets a single slash match multiple adjacent slashes in the
6628 URL. This change is for consistency with RewriteRule and
6629 AliasMatch. Multiple slashes have meaning in URLs that they do
6630 not have in (some) filesystems. Location on the other hand can
6631 be considered a shorthand for a more complicated regex, and it
6632 does match multiple slashes with a single slash -- which is
6633 also consistent with the Alias directive.
6634 [Dean Gaudet] related PR#1440
6636 *) Fix bug with mod_mime_magic causing certain files, including files
6637 of length 0, to result in no response from the server.
6640 *) The Configure script now generates src/include/ap_config.h which
6641 contains the set of defines used when Apache is compiled on a platform.
6642 This file can then be included by external modules before including
6643 any Apache header files in case they are being built separately from
6644 Apache. Along with this change, a couple of minor changes were
6645 made to make Apache's #defines coexist peacefully with any autoconf
6646 defines an external module might have. [Rasmus Lerdorf]
6648 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6649 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6650 chance by the API to initialize its per-server configuration and thus
6651 receives the wrong one from the main server. This is now avoided by
6652 remembering the server together with the config structure while
6653 configuring and later assuming there is no config when we see a
6654 difference between the remembered server and the one calling us.
6655 [Ralf S. Engelschall] PR#1790
6657 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6658 is automatically disabled under configure time when the dbm_xxx functions
6659 are not available. Second, two heavy source code errors in the DBM
6660 support code were fixed. This makes DBM RewriteMap's usable again after
6661 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6663 *) Now all configuration files support Unix-style line-continuation via
6664 the trailing backslash ("\") character. This enables us to write down
6665 complex or just very long directives in a more readable way. The
6666 backslash character has to be really the last character before the
6667 newline and it has not been prefixed by another (escaping) backslash.

6673 *) To deal with modules being compiled and [dynamically] linked
6674 at a different time from the core, the SERVER_VERSION and
6675 SERVER_BUILT symbols have been abstracted through the new
6676 API routines apapi_get_server_version() and apapi_get_server_built().
6679 *) WIN32: Preserve trailing slash in canonical path (and hence
6680 in PATH_INFO). [Paul Sutton, Ben Laurie]
6682 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6683 depending on the rev of Solaris and what mixture of modules
6684 are in use. So it has been disabled, and Solaris is back to
6685 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6686 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6687 up static content only servers. Or it may fail unpredictably.
6688 [Dean Gaudet] PR#1779, 1854, 1904
6690 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6693 *) API: Rewrite of absoluteURI handling, and in particular how
6694 absoluteURIs match vhosts. Unless a request is a proxy request, a
6695 "http://host" url is treated as if a similar "Host:" header had been
6696 supplied. This change was made to support future HTTP/1.x protocols
6697 which may require clients to send absoluteURIs for all requests.
6699 In order to achieve this change subtle changes were made to the API. In a
6700 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6701 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6702 by the core, modules must set it during the post_read_request or
6703 translate_names phase.
6705 Plus changes to the virtualhost test suite for absoluteURI testing.
6707 This fixes several bugs with the proxy proxying requests to vhosts
6708 managed by the same httpd.
6711 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6712 code from mod_rewrite. The vhost matching is now performed by a
6713 globally available function matches_request_vhost(). [Dean Gaudet]

6729 *) API: A new source module main/util_uri.c; It contains a routine
6730 parse_uri_components() and friends which breaks a URI into its component
6731 parts. These parts are stored in a uri_components structure called
6732 parsed_uri within each request_rec, and are available to all modules.
6733 Additionally, an unparse routine is supplied which re-assembles the URI
6734 components back to an URI, optionally hiding the username:password@ part
6735 from ftp proxy requests, and other useful routines. Within the structure,
6736 you find on a ready-for-use basis:
6737 scheme; /* scheme ("http"/"ftp"/...) */
6738 hostinfo; /* combined [user[:password]@]host[:port] */
6739 user; /* user name, as in http://user:passwd@host:port/ */
6740 password; /* password, as in http://user:passwd@host:port/ */
6741 hostname; /* hostname from URI (or from Host: header) */
6742 port_str; /* port string (integer representation is in "port") */
6743 path; /* the request path (or "/" if only scheme://host was given) */
6744 query; /* Everything after a '?' in the path, if present */
6745 fragment; /* Trailing "#fragment" string, if present */
6746 This is meant to serve as the platform for *BIG* savings in
6747 code complexity for the proxy module (and maybe the vhost logic).
6750 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6751 ${map:key}) available for all location where a string is created in
6752 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6753 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6754 possible expansions are consequently usable at all string creation
6755 locations. [Ralf S. Engelschall]
6757 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6758 and not 1) and the per-virtual-server merging of directives. Now all
6759 directives except `RewriteEngine' and `RewriteOption' are either
6760 completely overridden (default) or completely inherited (when
6761 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6767 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause

6770 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6771 (like SunOS and FreeBSD) which don't accept the locking of pipes
6772 directly. A new directive RewriteLock is introduced which can be used to
6773 setup a separate locking file which then is used for synchronization.

6789 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6791 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6792 type but with a special post-processing for the looked-up value: It
6793 parses it into alternatives according to `|' chars and then only one
6794 particular alternative is chosen randomly (this is an essential
6795 functionality needed for balancing between backend-servers when using
6796 Apache as a Reverse Proxy. The looked up value here is a list of
6797 servers). Second, `int' with the built-in maps named `tolower' and
6798 `toupper' which can be used to map URL parts to a fixed case (this is an
6799 essential feature to fix the case of server names when doing mass
6800 virtual-hosting with the help of mod_rewrite instead of using
6801 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6802 Jay Soffian <jay@cimedia.com>] PR#1631
6804 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6805 This directive lets Apache adjust the URL in Location-headers on HTTP
6806 redirect responses sent by the remote server. This way the virtually
6807 mapped area is no longer left on redirects and thus by-passed which is
6808 especially essential when running Apache as a reverse proxy.

6932 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
6933 instead of AddModule in Configuration to build shared modules
6934 [Sameer Parekh, Paul Sutton]
6936 *) Minor cleanups to r->finfo handling in some modules.
6939 *) Abstract read()/write() to ap_read()/ap_write().
6940 Makes it easier to add other types of IO code such as SFIO.
6943 *) API: Generalize default_port manipulations to make support of
6944 different protocols easier. [Ben Laurie, Randy Terbush]
6946 *) There are many cases where users do not want Apache to form
6947 self-referential urls using the "canonical" ServerName and Port.
6948 The new UseCanonicalName directive (default on), if set to off

6954 PR#315, 459, 485, 1433
6956 *) Yet another rearrangement of the source tree.. now all the common
6957 header files are in the src/include directory. The -Imain -Iap
6958 references in Makefiles have been changed to the simpler -Iinclude
6959 instead. In addition to simplifying the build a little bit, this
6960 also makes it clear when a module is referencing something in a
6961 other than kosher manner (e.g., the proxy including mod_mime.h).
6962 Module-private header files (the proxy, mod_mime, the regex library,
6963 and mod_rewrite) have not been moved to src/include; nor have
6964 the OS-abstraction files. [Ken Coar]
6966 *) Fix a bug where r->hostname didn't have the :port stripped
6967 from it. [Dean Gaudet]
6969 *) Tweaked the headers_out table size, and the subprocess_env
6970 table size guess in rename_original_environment(). Added
6971 MAKE_TABLE_PROFILE which can help discover make_table()
6972 calls that use too small an initial guess, see alloc.c.
6975 *) Options and AllowOverride weren't properly merging in the main
6976 server setting inside vhosts (only an issue when you have no
6977 <Directory> or other section containing an Options that affects
6978 a request). Options +foo or -foo in the main_server wouldn't
6979 affect the main_server's lookup defaults. [Dean Gaudet]
6981 *) Variable 'cwd' was being used pointlessly before being set.
6984 *) r->allowed handling cleaned up in the standard modules.
6987 *) Some case-sensitivity issues cleaned up to be consistent with
6988 RFC2068. [Dean Gaudet]
6990 *) SIGURG doesn't exist everywhere.
6991 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6993 *) mod_unique_id was erroneously generating a second unique id when
6994 an internal redirect occured. Such redirects occur, for example,
6995 when processing a DirectoryIndex match. [Dean Gaudet]
6997 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6998 of the key and value. But in many cases this is not required
6999 because the key/value is a constant, or the value has been built
7000 by pstrcat() or other similar means. New routines table_addn,
7001 table_mergen, and table_setn have been added to the API, these
7002 routines do not pstrdup() their arguments. The core code and
7003 standard modules were changed to take advantage of these routines.
7004 The resulting server is up to 20% faster in some situations.
7006 Note that it is easy to get code subtly wrong if you pass a key/value
7007 which is in a pool other than the pool of the table. The only
7008 safe thing to do is to pass key/values which are in the pool of
7009 the table, or in one of the ancestors of the pool of the table.
7010 i.e. if the table is part of a subrequest, a value from the main
7011 request's pool is OK since the subrequest pool is a sub_pool of the
7012 main request's pool (and therefore has a lifespan at most as long as
7013 the main pool). There is debugging code which can detect improper
7014 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
7015 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
7017 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
7018 which don't exist on disk more gracefully; handles vhosts properly.
7019 Update documentation to reflect the code -- if there's no
7020 MimeMagicFile directive then the module is not enabled.
7023 *) PORT: Some older *nix dialects cannot automatically start scripts
7024 which begin with a #! interpreter line (the shell starts the scripts
7025 appropriately on these platforms). Apache now supports starting of
7026 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
7027 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
7030 *) API: "typedef array_header table" removed from alloc.h, folks should
7031 have been writing to use table as if it were an opaque type, but even
7032 some standard modules got this wrong. By changing the definition
7033 to "typedef struct table table" module authors will receive compile
7034 time warnings that they're doing the wrong thing. This change
7035 facilitates future changes with more sophisticated table
7036 structures. Specifically, module authors should be using table_elts()
7037 to get access to an array_header * for the table. [Dean Gaudet]
7039 *) API: Renamed new_connection() to avoid namespace collision with LDAP
7040 library routines. [Ken Coar, Rasmus Lerdorf]
7042 *) WIN32: mod_speling is now available on the Win32 platform.
7045 *) For clarity the following compile time definition was changed:
7047 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
7049 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
7050 and not be a general notice that the OS has mmap(). Now the
7051 HAVE_MMAP/SHMGET #defines strictly are informational that the
7052 OS has that method of shared memory; the type to use for
7053 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
7054 and USE_SHMGET_SCOREBOARD). This allows outside modules to
7055 determine if shared memory is available and allows Apache
7056 to determine the best method to use for the scoreboard.
7059 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
7060 as do various earlier versions. It should be safe on all versions.

7084 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
7085 The choice of flock vs. fcntl was made based on timings which showed that
7086 even on non-NFS, non-exported filesystems fcntl() was an order of
7087 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7088 that single socket users will see no difference. [Dean Gaudet] PR#467

7552 *) New support tool: src/support/split-logfile, a sample Perl script which
7553 splits up a combined access log into separate files based on the
7554 name of the virtual host (listed first in the log records by "%v").
7557 Changes with Apache 1.3b2 (there is no 1.3b1)
7559 *) TestCompile was not passing $LIBS [Dean Gaudet]
7561 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7564 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7565 rudimentary memory debugger which can be used on live servers with
7566 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7567 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7568 and free() for each object. This is far more expensive and should
7569 only be used for testing with tools such as Electric Fence and
7570 Purify. See main/alloc.c for more details. [Dean Gaudet]
7572 *) Configure uses a sh trap and didn't set its exitcode properly.
7573 [Dean Gaudet] PR#1159
7575 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7576 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7577 From a given ip:port, regardless what the Host: header is, you can
7578 only reach the vhosts defined on that ip:port. The precedence of
7579 vhosts was reversed to match other precedences in the config --
7580 the earlier vhosts override the later vhosts. All vhost matching was
7581 moved into http_vhost.[ch]. [Dean Gaudet]
7583 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7584 be used for whatever reason is appropriate (i.e. format() warnings
7585 for printf style functions). Both are enabled only with
7586 gcc >= 2.7.x (so that we have fewer support issues with older
7587 versions). [Dean Gaudet]
7589 *) Fix support for Proxy Authentication (we were testing the response
7590 status too early). [Marc Slemko]
7592 *) CoreDumpDirectory directive directs where the core file is
7593 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7594 received. [Marc Slemko, Dean Gaudet]
7596 *) PORT: Support for Atari MINT.
7597 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7599 *) When booting, apache will now detach itself from stdin, stdout,
7600 and stderr. stderr will not be detached until after the config
7601 files have been read so you will be able to see initial error
7602 messages. After that all errors are logged in the error_log.
7603 This makes it more convenient to start apache via rsh, ssh,
7604 or crontabs. [Dean Gaudet] PR#523
7606 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7607 Also removed the auto-generated link to www.apache.org that was the
7608 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7610 *) send_fb would not detect aborted connections in some situations.
7613 *) mod_include would use uninitialized data when parsing certain
7614 expressions involving && and ||. [Brian Slesinsky] PR#1139
7616 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7618 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7620 *) mod_autoindex improperly counted &escapes; as more than one
7621 character in the description. It also improperly truncated
7622 descriptions that were exactly the maximum length.
7625 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7626 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7629 *) mod_include now uses symbolic names to check for request success
7630 and return HTTP errors, and correctly handles all types of
7631 redirections (previously it only did temporary redirect correctly).
7632 [Ken Coar, Roy Fielding]
7634 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7635 r->filename. Since those two are meant to be in sync with each other
7636 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7638 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7639 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7641 *) Inetd mode (which is buggy) uses timeouts without having setup the
7642 jmpbuffer. [Dean Gaudet] PR#1064
7644 *) Work around problem under Linux where a child will start looping
7645 reporting a select error over and over.
7646 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7648 *) Fixed error in proxy_util.c when looping through multiple host IP
7649 addresses. [Lars Eilebrecht] PR#974
7651 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7652 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7653 bytes before writing, but it will never split a log entry across a
7654 buffer boundary. [Dean Gaudet]
7656 *) API: the short_score record has been split into two pieces, one which
7657 the parent writes on, and one which the child writes on. As part of
7658 this change the get_scoreboard_info() function was removed, and
7659 scoreboard_image was exported. This change fixes a race condition
7660 in file based scoreboard systems, and speeds up changes involving the
7661 scoreboard in earlier 1.3 development. [Dean Gaudet]
7663 *) API: New register_other_child() API (see http_main.h) which allows
7664 modules to register children with the parent for maintenance. It
7665 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7667 *) API: New piped_log API (see http_log.h) which implements piped logs,
7668 and will use register_other_child to implement reliable piped logs
7669 when it is available. The reliable piped logs part can be disabled
7670 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7671 logs is only available on Unix. [Dean Gaudet]
7673 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7674 meets_conditions(). This allows conditional HTTP selection to be
7675 handled separately from the storing of the header fields, and provides
7676 the ability for CGIs to set their own ETags for conditional checking.
7677 [Ken Coar, Roy Fielding] PR#895
7679 *) Changes to mod_log_config to allow naming of format strings.
7680 Format nicknames are defined with "LogFormat fmt nickname", and can
7681 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7684 *) New module, "mod_speling", which can help find files even when
7685 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7687 *) API: New function child_terminate() triggers the child process to
7688 exit, while allowing the child finish what it needs to for the
7689 current request first.
7690 [Doug MacEachern, Alexei Kosut]
7692 *) Windows now defaults to using full status reports with mod_status.
7693 [Alexei Kosut] PR #1094
7695 *) *Really* disable all mod_rewrite operations if the engine is off.
7696 Some things (like RewriteMaps) were checked/performed even if they
7697 weren't supposed to be. [Ken Coar] PR #991
7699 *) Implement a new timer scheme which eliminates the need to call alarm() all
7700 the time. Instead a counter in the scoreboard for each child is used to
7701 show when the child has made forward progress. The parent samples this
7702 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7703 progress has been made in the timeout period. This reduces the static
7704 request best-case syscall count to 22 from 29. This scheme is only
7705 used by systems with memory-based scoreboards. [Dean Gaudet]
7707 *) The proxy now properly handles CONNECT requests which are sent
7708 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7710 *) A script called apachectl has been added to the support
7711 directory. This script allows you to do things such as
7712 "apachectl start" and "apachectl restart" from the command
7715 *) Modules and core routines are now put into libraries, which
7716 simplifies the link line tremendously (among other advantages).
7719 *) Some of the MD5 names defined in Apache have been renamed to have
7720 an `ap_' prefix to avoid conflicts with routines supplied by
7721 external libraries. [Ken Coar]
7723 *) Removal of mod_auth_msql.c from the distribution. There are many
7724 other options for databases today. Rather than offer one option,
7725 offer none at this time. mod_auth_msql and other SQL database
7726 authentication modules can be found at the Apache Module Registry.
7727 http://modules.apache.org/ It would be nice to offer a generic
7728 mod_auth_sql option in the near future.
7730 *) PORT: BeOS support added [Alexei Kosut]
7732 *) Configure no longer accepts the -make option, since it creates
7733 Makefile on the fly based on Makefile.tmpl and Configuration.
7735 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7736 of forcibly killing off all its processes and exiting without
7737 cleaning up. [Alexei Kosut]
7739 *) API: A new field in the request_rec, r->mtime, has been added to
7740 avoid gratuitous parsing of date strings. It is intended to hold
7741 the last-modified date of the resource (if applicable). An
7742 update_mtime() routine has also been added to advance it if
7743 appropriate. [Roy Fielding, Ken Coar]
7745 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7746 deny access to the directory with a HTTP_FORBIDDEN. The previous
7747 behavior was to ignore the htaccess file if it could not be read.
7748 This change may make some setups with unreadable htaccess files
7749 stop working. [Marc Slemko] PR#817
7751 *) Add aplog_error() providing a mechanism to define levels of
7752 verbosity to the server error logging. This addition also provides
7753 the ability to log errors using syslogd. Error logging is configurable
7754 on a per-server basis using the LogLevel directive. Conversion
7755 of log_*() in progress. [Randy Terbush]
7757 *) Further enhance aplog_error() to not log filename, line number, and
7758 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7760 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7761 converted to long ones. Backslashes are converted to forward
7762 slashes. Case is converted to lower. Parts of URLs that do not
7763 correspond to files are left completely alone. [Ben Laurie]
7765 *) PORT: 2 new OSs added to the list of ports:
7766 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7767 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7769 *) Add the server version (SERVER_VERSION macro) to the "server
7770 configured and running" entry in the error_log. Also build an
7771 object file at link-time that contains the current time
7772 (SERVER_BUILT global const char[]), and include that in the
7775 *) Set r->headers_out when sending responses from the proxy.
7776 This fixes things such as the logging of headers sent from
7777 the proxy. [Marc Slemko] PR#659
7779 *) support/httpd_monitor is no longer distributed because the
7780 scoreboard should not be file based if at all possible. Use
7781 mod_status to see current server snapshot.
7783 *) (set_file_slot): New function, allowing auth directives to be
7784 independent of the server root, so the server documents can be
7785 moved to a different directory or machine more easily.
7786 [David J. MacKenzie]
7788 *) If no TransferLog is given explicitly, decline
7789 to log. This supports coexistence with other logging modules,
7790 such as the custom one that UUNET uses. [David J. MacKenzie]
7792 *) Check for titles in server-parsed HTML files.
7793 Ignore leading newlines and returns in titles. The old behavior
7794 of replacing a newline after <title> with a space causes the
7795 title to be misaligned in the listing. [David J. MacKenzie]
7797 *) Change mod_cern_meta to be configurable on a per-directory basis.
7798 [David J. MacKenzie]
7800 *) Add 'Include' directive to allow inclusion of configuration
7801 files within configuration files. [Randy Terbush]
7803 *) Proxy errors on connect() are logged to the error_log (nothing
7804 new); now they include the IP address and port that failed
7805 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7807 *) Various architectures now define USE_MMAP_FILES which causes
7808 the server to use mmap() for static files. There are two
7809 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7810 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7811 number of bytes written in one cycle from a single mmap()d object,
7812 default 32768). [Dean Gaudet]
7814 *) API: Added post_read_request API phase which is run right after reading
7815 the request from a client, or right after an internal redirect. It is
7816 useful for modules setting environment variables that depend only on
7817 the headers/contents of the request. It does not run during subrequests
7818 because subrequests inherit pretty much everything from the main
7819 request. [Dean Gaudet]
7821 *) Added mod_unique_id which is used to generate a unique identifier for
7822 each hit, available in the environment variable UNIQUE_ID.
7825 *) init_modules is now called after the error logs have been opened. This
7826 allows modules to emit information messages into the error logs.
7829 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7830 information for case where proxy module is not available. [Marc Slemko]
7832 *) PORT: Apache has need for mutexes to serialize its children around
7833 accept. In prior versions either fcntl file locking or flock file
7834 locking were used. The method is chosen by the definition of
7835 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7836 and FLOCK for flock(). New options have been added:
7837 - SYSVSEM to use System V style semaphores
7838 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7839 - USLOCK to use IRIX uslock
7840 Based on timing various techniques, the following changes were made
7842 - Linux 2.x uses flock instead of fcntl
7843 - Solaris 2.x uses pthreads
7844 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7845 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7846 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7847 Martijn Koster <m.koster@pobox.com>]
7849 *) PORT: The semantics of accept/select make it very desirable to use
7850 mutexes to serialize accept when multiple Listens are in use. But
7851 in the case where only a single socket is open it is sometimes
7852 redundant to serialize accept(). Not all unixes do a good job with
7853 potentially dozens of children blocked on accept() on the same
7854 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7855 the server will avoid serialization when listening on only one socket,
7856 and use serialization when listening on multiple sockets.
7857 [Dean Gaudet] PR#467
7859 *) Configure changes: TestLib replaced by TestCompile, which has
7860 some additional capability (such as doing a sanity check of
7861 the compiler and flags selected); the version of Solaris is now
7862 available via the #define value of SOLARIS2; IRIX n32bit libs
7863 now supported and selectable by new Configuration Rule: IRIXN32;
7864 We no longer default to -O2 optimization. [Jim Jagielski]
7866 *) Updated Configure: Configuration now uses AddModule to specify
7867 module source or binary file location, relative to src directory.
7868 Modules can be dropped into modules/extra, or in their own
7869 directory, and modules can come with a Makefile or Configure can
7870 create one. Modules can add compiler or library information to
7871 generated Makefiles. [Paul Sutton]
7873 *) Source core re-organisation: distributed modules are now in
7874 modules/standard. All other source code is in main. OS-specific
7875 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7877 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7880 *) Fix another long-standing bug in sub_req_lookup_file where it would
7881 happily skip past access checks on subdirectories looked up with
7882 relative paths. (It's used by mod_dir, mod_negotiation,
7883 and mod_include.) [Dean Gaudet]
7885 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7886 N is the number of <Directory> sections, and M is the number of
7887 components in the filename of an object.
7889 To achieve this optimization the following config changes were made:
7890 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7891 <Files>s, and <Location>s now treat a slash as a special
7892 character. For example "/home/*/public_html" previously would
7893 match "/home/a/andrew/public_html", now it only matches things
7894 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7895 - It's possible now to use [] wildcarding in <Directory>, <Files>
7897 - Regex <Directory>s are applied after all non-regex <Directory>s.
7901 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7902 and corrupted paths. [Dean Gaudet]
7904 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7905 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7906 be accessed now via backreferences $1..$9 in RewriteConds test-against
7907 strings in addition to RewriteRules subst string. Second the grouped
7908 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7909 via backreferences %1..%9 both in following RewriteCond test-against
7910 strings and RewriteRules subst string. This provides maximum flexibility
7911 through the use of backreferences.
7912 Additionally the rewriting engine was cleaned up by putting common
7913 code to the new expand_backrefs_inbuffer() function.
7914 [Ralf S. Engelschall]
7916 *) When merging the main server's <Directory> and <Location> sections into
7917 a vhost, put the main server's first and the vhost's second. Otherwise
7918 the vhost can't override the main server. [Dean Gaudet] PR#717
7920 *) The <Directory> code would merge and re-merge the same section after
7921 a match was found, possibly causing problems with some modules.
7924 *) ip-based vhosts are stored and queried using a hashing function, which
7925 has been shown to improve performance on servers with many ip-vhosts.
7926 Some other changes had to be made to accommodate this:
7927 - the * address for vhosts now behaves like _default_
7928 - the matching process now is:
7929 - match an ip-vhost directly via hash (possibly matches main
7931 - if that fails, just pretend it matched the main server
7932 - if so far only the main server has been matched, perform
7933 name-based lookups (ServerName, ServerAlias, ServerPath)
7934 *only on name-based vhosts*
7935 - if they fail, look for _default_ vhosts
7936 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7938 *) dbmmanage overhaul:
7939 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7940 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7941 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7942 - provide better seed for rand
7943 - prompt for password as per getpass(3) (turn off echo, read from
7945 - use "newstyle" crypt based on $Config{osname} ($^O)
7946 - will not add a user if already in database, use new `update' command
7948 - added `check' command to check a users' password
7949 - added `import' command to convert existing password text-files or
7950 dbm files exported with `view'
7951 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7954 *) Added psocket() which is a pool form of socket(), various places within
7955 the proxy weren't properly blocking alarms while registering the cleanup
7956 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7957 was a bug where the client socket was being close()d twice due a still
7958 registered cleanup. [Dean Gaudet]
7960 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7963 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7964 [Jason Venner <jason@idiom.com>] PR#667
7966 *) Enable ``=""'' for RewriteCond directives to match against
7967 the empty string. This is the preferred way instead of ``^$''.
7968 [Ralf S. Engelschall]
7970 *) Fixed an infinite loop in mod_imap for references above the server root
7971 [Dean Gaudet] PR#748
7973 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7974 SendBufferSize, so that the TCP window can be set appropriately
7975 for LFNs. [Phillip A. Prindeville]
7977 *) mod_browser has been replaced by the more general mod_setenvif
7978 (courtesy of Paul Sutton). BrowserMatch* directives are still
7979 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7980 UnSetEnvIfZero directives. [Ken Coar]
7982 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7983 order for remote_host to be set (for logging, or for the env var
7984 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7987 *) mod_access overhaul:
7988 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7989 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7990 - Critical path was sped up by pre-computing a few things at config time.
7991 - The undocumented syntax "allow user-agents" was removed,
7992 the replacement is "allow from env=foobar" combined with mod_browser.
7993 - When used with hostnames it now forces a double-reverse lookup
7994 no matter what the directory settings are. This double-reverse
7995 doesn't affect any of the other routines that use the remote
7996 hostname. In particular it's still passed to CGIs and the log
7997 without the double-reverse check. Related PR#860.
8000 *) When a large bwrite() occurs (larger than the internal buffer size),
8001 while there is already something in the buffer, apache will combine
8002 the large write and the buffer into a single writev(). (This is
8003 in anticipation of using mmap() for reading files.)
8006 *) In obscure cases where a partial socket write occurred while chunking,
8007 Apache would omit the chunk header/footer on the next block. Cleaned
8008 up other bugs/inconsistencies in error conditions in buff.c. Fixed
8009 a bug where a long pause in DNS lookups could cause the last packet
8010 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
8012 *) API: Added child_exit function to module structure. This is called
8013 once per "heavy-weight process" just before a server child exit()'s
8014 e.g. when max_requests_per_child is reached, etc.
8015 [Doug MacEachern, Dean Gaudet]
8017 *) mod_include cleanup showed that handle_else was being used to handle
8018 endif. It didn't cause problems, but it was cleaned up too.
8021 *) mod_cern_meta would attempt to find meta files for the directory itself
8022 in some cases, but not in others. It now avoids it in all cases.
8025 *) mod_mime_magic would core dump if there was a decompression error.
8026 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
8028 *) PORT: some variants of DGUX require -lsocket -lnsl
8029 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
8031 *) mod_autoindex now allows sorting of FancyIndexed directory listings
8032 by the various fields (name, size, et cetera), either in ascending
8033 or descending order. Just click on the column header. [Ken Coar]
8035 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
8036 CPUs like the Alpha. Apache still stores ints in pointers, but that's
8037 the relatively safe direction. [Dean Gaudet] PR#344
8039 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
8040 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
8042 *) child_main avoids an unneeded call to select() when there is only one
8043 listening socket. [Dean Gaudet]
8045 *) In the event that the server is starved for idle servers it will
8046 spawn 1, then 2, then 4, ..., then 32 servers each second,
8047 doubling each second. It'll also give a warning in the errorlog
8048 since the most common reason for this is a poor StartServers
8049 setting. The define MAX_SPAWN_RATE can be used to raise/lower
8050 the maximum. [Dean Gaudet]
8052 *) Apache now provides an effectively unbuffered connection for
8053 CGI scripts. This means that data will be sent to the client
8054 as soon as the CGI pauses or stops output; previously, Apache would
8055 buffer the output up to a fixed buffer size before sending, which
8056 could result in the user viewing an empty page until the CGI finished
8057 or output a complete buffer. It is no longer necessary to use an
8058 "nph-" CGI to get unbuffered output. Given that most CGIs are written
8059 in a language that by default does buffering (e.g. perl) this
8060 shouldn't have a detrimental effect on performance.
8062 "nph-" CGIs, which formerly provided a direct socket to the client
8063 without any server post-processing, were not fully compatible with
8064 HTTP/1.1 or SSL support. As such they would have had to implement
8065 the transport details, such as encryption or chunking, in order
8066 to work properly in certain situations. Now, the only difference
8067 between nph and non-nph scripts is "non-parsed headers".
8068 [Dean Gaudet, Sameer Parekh, Roy Fielding]
8070 *) If a BUFF is switched from buffered to unbuffered reading the first
8071 bread() will return whatever remained in the buffer prior to the
8072 switch. [Dean Gaudet]
8074 Changes with Apache 1.3a1
8076 *) Added another Configure helper script: TestLib. It determines
8077 if a specified library exists. [Jim Jagielski]
8079 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8080 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8083 *) PORT: Some architectures use size_t for various lengths in network
8084 functions such as accept(), and getsockname(). The definition
8085 NET_SIZE_T is used to control this. [Dean Gaudet]
8087 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8088 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8089 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8091 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8092 [Igor N Kovalenko <infoh@mail.wplus.net>]
8094 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8095 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8096 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8097 [Dean Gaudet] related PR#875
8099 *) API: Correct child_init() slot declaration from int to void, to
8100 match the init() declaration. Update mod_example to use the new
8103 *) added transport handle slot (t_handle) to the BUFF structure
8106 *) get_client_block() returns wrong length if policy is
8107 REQUEST_CHUNKED_DECHUNK.
8108 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
8110 *) Support the image map format of FrontPage. For example:

8114 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
8115 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
8117 *) AddModuleInfo directive for mod_info which allows you to annotate
8118 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8120 *) Added NoProxy directive to avoid using ProxyRemote for selected
8121 addresses. Added ProxyDomain directive to cause unqualified
8122 names to be qualified by redirection.
8123 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8125 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8126 header to the remote host in the proxy. [Sameer Parekh and
8129 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8130 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8131 URLs, fixed rewritelog(), fixed forced response code handling on
8132 redirects from within .htaccess files, disabled pipe locking under
8133 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8134 no substitution, bugfixed situations where HostnameLookups is off, made
8135 mod_rewrite more thread-safe for NT port and fixed problem when creating
8136 an empty query string via "xxx?".
8137 This update also removes the copyright of Ralf S. Engelschall,
8138 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8139 exclusively copyrighted by the Apache Group now. This happened because
8140 the author now has gifted mod_rewrite exclusively to the Apache Group and
8141 no longer maintains an external version.
8142 [Ralf S. Engelschall]
8144 *) API: Added child_init function to module structure. This is called
8145 once per "heavy-weight process" before any requests are handled.
8146 See http_config.h for more details. [Dean Gaudet]
8148 *) Anonymous_LogEmail was logging on each subrequest.
8149 [Dean Gaudet] PR#421, 868
8151 *) API: Added is_initial_req() which tests if the request being
8152 processed is the initial request, or a subrequest.
8155 *) Extended SSI (mod_include) now handles additional relops for
8156 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8158 *) Configure fixed to correctly propagate user-selected options and
8159 settings (such as CC and OPTIM) to Makefiles other than
8160 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8162 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8163 directory indices to start with the contents of the HeaderName file
8164 if there is one. If there isn't one, the behaviour is unchanged.
8165 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8167 *) WIN32: Modules can now be dynamically loaded DLLs using the
8168 LoadModule/LoadFile directives. Note that module DLLs must be
8169 compiled with the multithreaded DLL version of the runtime library.
8170 [Alexei Kosut and Ben Laurie]
8172 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8173 This allows the admin to completely remove automatic indexing
8174 from the server, while still supporting the basic functions of
8175 trailing-slash redirects and DirectoryIndex files. Note that if
8176 you're carrying over an old Configuration file and you use directory
8177 indexing then you'll want to add:
8179 Module autoindex_module mod_autoindex.o
8181 before mod_dir in your Configuration. [Dean Gaudet]
8183 *) popendir/pclosedir created to properly protect directory scanning.
8184 [Dean Gaudet] PR#525
8186 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8187 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8188 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8191 *) The AccessFileName directive can now take more than one filename.
8192 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8194 *) The new mod_mime_magic can be used to "magically" determine the type
8195 of a file if the extension is unknown. Based on the unix file(1)
8196 command. [Ian Kluft <ikluft@cisco.com>]
8198 *) We now determine and display the time spent processing a
8199 request if desired. [Jim Jagielski]
8201 *) mod_status: PID field of "dead" child slots no longer displays
8202 main httpd process's PID. [Jim Jagielski]
8204 *) Makefile.nt added - to build all the bits from the command line:
8205 nmake -f Makefile.nt
8206 Doesn't yet work properly. [Ben Laurie]
8208 *) Default text of 404 error is now "Not Found" rather than the
8209 potentially misleading "File Not Found". [Ken Coar]
8211 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8212 for the net if we require people that actually need this data to
8213 enable it. [Linus Torvalds]
8215 *) directory_walk() is an expensive function, keep a little more state to
8216 avoid needless string counting. Add two new functions make_dirstr_parent
8217 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8218 The new functions are a little less general than make_dirstr, but
8219 work more efficiently (less memory, less string counting).
8222 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8223 to LDFLAGS) to avoid complications with lex rules in make files.
8224 [Dean Gaudet] PR#372
8226 *) run_method optimized to avoid needless scanning over NULLs in the
8227 module list. [Dean Gaudet]
8229 *) Revamp of (unix) scoreboard management code such that it avoids
8230 unnecessary traversals of the scoreboard on each hit. This is
8231 particularly important for high volume sites with a large
8232 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8233 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8234 httpd.h. [Dean Gaudet]
8236 *) In configurations using multiple Listen statements it was possible for
8237 busy sockets to starve other sockets of service. [Dean Gaudet]
8239 *) Added hook so standalone_main can be replaced at compile time
8240 (define STANDALONE_MAIN)
8243 *) Lowest-level read/write functions in buff.c will be replaced with
8244 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8245 compile time. The default sfio discipline will behave as apache
8246 would without sfio compiled in.
8249 *) Enhance UserDir directive (mod_userdir) to accept a list of
8250 usernames for the 'disable' keyword, and add 'enable user...' to
8251 selectively *en*able userdirs if they're globally disabled.
8254 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8255 will work with Netscape dbm files. (dbmmanage will probably not
8256 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8258 *) Add a ListenBacklog directive to control the backlog parameter
8259 passed to listen(). Also change the default to 511 from 512.
8262 *) API: A new handler response DONE which informs apache that the
8263 request has been handled and it can finish off quickly, similar to
8264 how it handles errors. [Rob Hartill]
8266 *) Turn off chunked encoding after sending terminating chunk/footer
8267 so that we can't do it twice by accident. [Roy Fielding]
8269 *) mod_expire also issues Cache-Control: max-age headers.
8272 *) API: Added kill_only_once option for free_proc_chain so that it won't
8273 aggressively try to kill off specific children. For fastcgi.
8274 [Stanley Gambarin <gambarin@OpenMarket.com>]
8276 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8278 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8279 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8280 attributes in the FancyIndexing IMG tags. [Ken Coar]
8282 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8284 *) PORT: Added Windows NT support
8285 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8287 Changes with Apache 1.2.6
8289 *) mod_include when using XBitHack Full would send ETags in addition to
8290 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8291 [Dean Gaudet] PR#1133
8293 *) SECURITY: When a client connects to a particular port/addr, and
8294 gives a Host: header ensure that the virtual host requested can
8295 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8297 *) Support virtual hosts with wildcard port and/or multiple ports
8298 properly. [Ed Korthof <ed@organic.com>]
8300 *) Fixed some case-sensitivity issues according to RFC2068.
8303 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8304 and mod_include.c. [Dean Gaudet]
8306 *) Variable 'cwd' was being used pointlessly before being set.
8309 *) SIGURG doesn't exist on all platforms.
8310 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8312 *) When an error occurs during a POST, or other operation with a
8313 request body, the body has to be read from the net before allowing
8314 a keepalive session to continue. [Roy Fielding] PR#1399
8316 *) When an error occurs in fcntl() locking suggest the user look up
8317 the docs for LockFile. [Dean Gaudet]
8319 *) table_set() and table_unset() did not deal correctly with
8320 multiple occurrences of the same key. [Stephen Scheck
8321 <sscheck@infonex.net>, Ben Laurie] PR#1604
8323 *) send_fd_length() did not calculate total_bytes_sent properly in error
8324 cases. [Ben Reser <breser@regnow.com>] PR#1366
8326 *) r->connection->user was allocated in the wrong pool causing corruption
8327 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8329 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8330 Also removed the auto-generated link to www.apache.org that was the
8331 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8333 *) Multiple "close" tokens may have been set in the "Connection"
8334 header, not an error, but a waste.
8335 [Ronald.Tschalaer@psi.ch] PR#1683
8337 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8338 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8340 *) It appears the "257th byte" bug (see
8341 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8342 at the 256th byte as well. Fixed. [Dean Gaudet]
8344 *) mod_rewrite would not handle %3f properly in some situations.
8347 *) Apache could generate improperly chunked HTTP/1.1 responses when
8348 the bputc() or rputc() functions were used by modules (such as
8349 mod_include). [Dean Gaudet]
8351 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8352 some ports. [Ralf Engelschall]
8354 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8356 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8358 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8360 Changes with Apache 1.2.5
8362 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8363 only an issue on systems without a MAXDNAME define or where
8364 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8366 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8369 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8370 directory listings. [Marc Slemko]
8372 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8375 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8376 is used to read various types of files such as htaccess and
8377 htpasswd files. [Marc Slemko]
8379 *) SECURITY: Ensure that the buffer returned by ht_time is always
8380 properly null terminated. [Marc Slemko]
8382 *) SECURITY: General mod_include cleanup, including fixing several
8383 possible buffer overflows and a possible infinite loop. This cleanup
8384 was done against 1.3 code and then backported to 1.2, the result
8385 is a large difference (due to indentation cleanup in 1.3 code).
8386 Users interested in seeing a smaller set of relevant differences
8387 should consider comparing against src/modules/standard/mod_include.c
8388 from the 1.3b3 release. Non-indentation changes to mod_include
8389 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8391 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8392 including fixing a possible buffer overflow. This cleanup also
8393 was done with 1.3 code as a basis, see the the previous note
8394 about mod_include. [Dean Gaudet]
8396 *) SECURITY: If a htaccess file can not be read due to bad
8397 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8398 The previous behavior was to ignore the htaccess file if it could not
8399 be read. This change may make some setups with unreadable
8400 htaccess files stop working. PR#817 [Marc Slemko]
8402 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8403 Make it O(n). This inefficiency could be used to mount a denial
8404 of service attack against the Apache server. Thanks to
8405 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
8408 *) mod_include used uninitialized data for some uses of && and ||.

8412 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
8414 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
8416 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
8417 r->filename. Since those two are meant to be in sync with each other
8418 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
8420 *) mod_include did not properly handle all possible redirects from sub-
8421 requests. [Ken Coar]
8423 *) Inetd mode (which is buggy) uses timeouts without having setup the
8424 jmpbuffer. [Dean Gaudet] PR#1064
8426 *) Work around problem under Linux where a child will start looping
8427 reporting a select error over and over.
8428 [Rick Franchuk <rickf@transpect.net>] PR#1107
8430 Changes with Apache 1.2.4
8432 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8433 always making requests with the full-URI instead of just the URI path.
8434 [Marc Slemko, Roy Fielding]
8436 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8437 on this platform. [Marc Slemko]
8439 Changes with Apache 1.2.3
8441 *) The request to a remote proxy was mangled if it was generated as the
8442 result of a ProxyPass directive. URL schemes other than http:// were not
8443 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
8444 PR#812 [Lars Eilebrecht]
8446 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8447 information for case where proxy module is not available. [Marc Slemko]
8449 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8450 do for errors and cached responses. [Roy Fielding]
8452 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8454 Changes with Apache 1.2.2 [not released]
8456 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8457 happily skip past access checks on subdirectories looked up with relative
8458 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8461 *) Add lockfile name to error message printed out when
8462 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8465 *) Enhanced the chunking and error handling inside the buffer functions.
8466 [Dean Gaudet, Roy Fielding]
8468 *) When merging the main server's <Directory> and <Location> sections into
8469 a vhost, put the main server's first and the vhost's second. Otherwise
8470 the vhost can't override the main server. [Dean Gaudet] PR#717
8472 *) The <Directory> code would merge and re-merge the same section after
8473 a match was found, possibly causing problems with some modules.
8476 *) Fixed an infinite loop in mod_imap for references above the server root.
8477 [Dean Gaudet] PR#748
8479 *) mod_include cleanup showed that handle_else was being used to handle
8480 endif. It didn't cause problems, but it was cleaned up too.
8483 *) Last official synchronization of mod_rewrite with author version (because
8484 mod_rewrite is now directly developed by the author at the Apache Group):
8485 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8486 minus WIN32/NT stuff, but plus copyright removement.
8488 - workaround for detecting infinite rewriting loops
8489 - fixed setting of env vars when "-" is used as subst string
8490 - fixed forced response code on redirects (PR#777)
8491 - fixed cases where r->args is ""
8492 - kludge to disable locking on pipes under braindead SunOS
8493 - fix for rewritelog in cases where remote hostname is unknown
8494 - fixed totally damaged request_rec walk-back loop
8495 o remove static from local data and add static to global ones.
8496 o replaced ugly proxy finding stuff by simple
8497 find_linked_module("mod_proxy") call.
8498 o added missing negation char on rewritelog()
8499 o fixed a few comment typos
8500 [Ralf S. Engelschall]
8502 *) Anonymous_LogEmail was logging on each subrequest.
8503 [Dean Gaudet] PR#421, PR#868
8505 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8506 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8507 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

8530 *) API: In HTTP/1.1, whether or not a request message contains a body
8531 is independent of the request method and based solely on the presence
8532 of a Content-Length or Transfer-Encoding. Therefore, our default
8533 handlers need to be prepared to read a body even if they don't know
8534 what to do with it; otherwise, the body would be mistaken for the
8535 next request on a persistent connection. discard_request_body()
8536 has been added to take care of that. [Roy Fielding] PR#378

8544 Changes with Apache 1.2.1
8546 *) SECURITY: Don't serve file system objects unless they are plain files,
8547 symlinks, or directories. This prevents local users from using pipes
8548 or named sockets to invoke programs for an extremely crude form of
8551 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
8552 could contain "../" allowing a local user to "publish" any file on
8553 the system. No slashes are allowed now. [Dean Gaudet]
8555 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8556 (headers, readmes, titles), mod_negotiation (type maps), or
8557 mod_cern_meta (meta files). [Dean Gaudet]
8559 *) SECURITY: Apache will refuse to run as "User root" unless
8560 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8562 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8563 if it contained a .htaccess disallowing symlinks. This is contrary
8564 to the rule that symlink permissions are tested with the symlink
8565 options of the parent directory. [Dean Gaudet] PR#353
8567 *) CONFIG: The LockFile directive can be used to place the serializing
8568 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8569 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8572 *) Request processing now retains state of whether or not the request
8573 body has been read, so that internal redirects and subrequests will
8574 not try to read it twice (and block). [Roy Fielding]
8576 *) Add a placeholder in modules/Makefile to avoid errors with certain
8577 makes. [Marc Slemko]

8585 *) Attempt to work around problems with third party libraries that do not
8586 handle high numbered descriptors (examples include bind, and
8587 solaris libc). On all systems apache attempts to keep all permanent
8588 descriptors above 15 (called the low slack line). Solaris users
8589 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8590 which keeps all non-FILE * descriptors above 255. On all systems
8591 this should make supporting large numbers of vhosts with many open
8592 log files more feasible. If this causes trouble please report it,
8593 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8594 [Dean Gaudet] various PRs
8596 *) Related to the last entry, network sockets are now opened before
8597 log files are opened. The only known case where this can cause
8598 problems is under Solaris with many virtualhosts and many Listen
8599 directives. But using -DHIGH_SLACK_LINE=256 described above will
8600 work around this problem. [Dean Gaudet]

8696 Module declaration. Also, be more understanding about the
8697 CC=/OPTIM= format in Configuration. Finally, fix compiler
8698 flags if using HP-UX's cc compiler. [Jim Jagielski]
8700 *) Subrequests and internal redirects now inherit the_request from the
8701 original request-line. [Roy Fielding]
8703 *) Test for error conditions before creating output header fields, since
8704 we don't want the error message to include those fields. Likewise,
8705 reset the content_language(s) and content_encoding of the response
8706 before generating or redirecting to an error message, since the new
8707 message will have its own Content-* definitions. [Dean Gaudet]
8709 *) Restored the semantics of headers_out (headers sent only with 200..299
8710 and 304 responses) and err_headers_out (headers sent with all responses).
8711 Avoid the overhead of copying tables if err_headers_out is empty
8712 (the usual case). [Roy Fielding]
8714 *) Fixed a couple places where a check for the default Content-Type was
8715 not properly checking both the value configured by the DefaultType
8716 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8717 of DEFAULT_TYPE to match the documented default (text/plain).

8720 *) Escape the HTML-sensitive characters in the Request-URI that is
8721 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8723 *) Properly initialize the flock structures used by the mutex locking
8724 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8727 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8728 (and NCSA httpd) definition wherein it was the extra path info beyond
8729 the CGI script filename. The environment variable FILEPATH_INFO has
8730 been removed, and instead we supply the original REQUEST_URI to any
8731 script that wants to be Apache-specific and needs the real URI path.
8732 This solves a problem with existing scripts that use extra path info
8733 in the ScriptAlias directive to pass options to the CGI script.
8736 *) The _default_ change in 1.2b10 will change the behaviour on configs
8737 that use multiple Listen statements for listening on multiple ports.
8738 But that change is necessary to make _default_ consistent with other
8739 forms of <VirtualHost>. It requires such configs to be modified
8740 to use <VirtualHost _default_:*>. The documentation has been
8741 updated. [Dean Gaudet] PR#530
8743 *) If an ErrorDocument CGI script is used to respond to an error
8744 generated by another CGI script which has already read the message
8745 body of the request, the server would block trying to read the
8746 message body again. [Rob Hartill]

8749 other platforms). Fixed. [Ben Laurie] PR#512

8767 Changes with Apache 1.2b9 [never announced]
8769 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8770 changes and in anticipation of 1.2 final release. [Roy Fielding]
8772 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8773 the connection (e.g., when user presses Stop). Apache will now stop
8774 trying to send a message body immediately after an error from write.
8775 [Roy Fielding and Nathan Kurz] PR#335
8777 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8778 than mod_alias, and mod_alias has higher priority than mod_proxy;
8779 rearranged other modules to enhance understanding of their purpose
8780 and relative order (and maybe even reduce some overhead).
8781 [Roy Fielding and Sameer Parekh]
8783 *) Fix graceful restart. Eliminate many signal-related race
8784 conditions in both forms of restart, and in SIGTERM. See
8785 htdocs/manual/stopping.html for details on stopping and
8786 restarting the parent. [Dean Gaudet]
8788 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8789 memory allocator to avoid a behaviour that required extra blocks to
8790 be allocated. [Dean Gaudet]
8792 *) Allow suexec to access files relative to current directory but not
8793 above. (Excluding leading / or any .. directory.) [Ken Coar]
8796 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8797 PR#367, 368, 354, 453

8800 while obtaining the /~user and save the username in a separate data
8801 area so that it won't be overwritten by the call to getgrgid(), and
8802 fix some misuse of the pool string allocation functions. Also fixes
8803 a general problem with parsing URL query info into args for CGI scripts.

8816 object that can't be PUT, or FOOBAR for some method FOOBAR that
8817 apache doesn't know about at all). Log 404s that occur in mod_include.
8818 [Paul Sutton, John Van Essen]
8820 *) If a soft timeout (or lingerout) occurs while trying to flush a
8821 buffer or write inside buff.c or fread'ing from a CGI's output,
8822 then the timeout would be ignored. [Roy Fielding] PR#373
8824 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8825 parsing of headers. If the terminating empty-line CRLF occurs starting
8826 at the 256th or 257th byte of output, then Navigator will think a normal
8827 image is invalid. We are guessing that this is because their initial
8828 read of a new request uses a 256 byte buffer. We check the bytes written
8829 so far and, if we are about to tickle the bug, we instead insert a
8830 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8832 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8833 of an external redirection. [Roy Fielding and Paul Sutton]
8835 *) Configure would create a broken Makefile if the configuration file
8836 contained a commented-out Rule. [Roy Fielding]
8838 *) Promote per_dir_config and subprocess_env from the subrequest to the
8839 main request in mod_negotiation. In particular this fixes a bug
8840 where <Files> sections wouldn't properly apply to negotiated content.
8843 *) Fix a potential deadlock in mod_cgi script_err handling.

8851 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8852 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8854 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8855 1.x the settings are those of pre-1.2b8. For 2.x we include
8856 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8857 HAVE_SYS_RESOURCE_H (enable the RLimit commands).

8873 *) Improve handling of directories when filenames have spaces in them.
8876 *) For hosts with multiple IP addresses, try all additional addresses if
8877 necessary to get a connect. Fail only if hostent address list is
8878 exhausted. [Chuck Murcko]
8880 *) More signed/unsigned port fixes. [Dean Gaudet]
8882 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8885 Changes with Apache 1.2b8
8887 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8888 to it. [Marc Slemko]
8890 *) The addition of <Location> and <File> directives made the
8891 sub_req_lookup_simple() function bogus, so we now handle
8892 the special cases directly. [Dean Gaudet]
8894 *) We now try to log where the server is dumping core when a fatal
8895 signal is received. [Ken Coar]
8897 *) Improved lingering_close by adding a special timeout, removing the
8898 spurious log messages, removing the nonblocking settings (they
8899 are not needed with the better timeout), and adding commentary
8900 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8901 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8903 *) Send error messages about setsockopt failures to the server error
8904 log instead of stderr. [Roy Fielding]
8906 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8908 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8909 processing a subrequest, allocate memory from r->main->pool instead
8910 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8911 in the middle of an SSI request. [Dean Gaudet] PR #122
8913 *) Fixed status of response when POST is received for a nonexistent URL
8914 (was sending 405, now 404) and when any method is sent with a
8915 full-URI that doesn't match the server and the server is not acting
8916 as a proxy (was sending 501, now 403). [Roy Fielding]
8918 *) Host port changed to unsigned short. [Ken Coar] PR #276
8920 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8922 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8924 *) Report extra info from errno with many errors that cause httpd to exit.
8925 spawn_child, popenf, and pclosef now have valid errno returns in the
8926 event of an error. Correct problems where errno was stomped on
8927 before being reported. [Dean Gaudet]
8929 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8930 never called, and thus the filesystem would remain full indefinitely.
8931 We now also remove incomplete cache files left if the origin server
8932 didn't send a Content-Length header and either the client has aborted
8933 transfer or bwrite() to client has failed. [Petr Lampa]
8935 *) Fixed the handling of module and script-added header fields.
8936 Improved the interface for sending header fields and reduced
8937 the duplication of code between sending okay responses and errors.
8938 We now always send both headers_out and err_headers_out, and
8939 ensure that the server-reserved fields are not being overridden,
8940 while not overriding those that are not reserved. [Roy Fielding]
8942 *) Moved transparent content negotiation fields to err_headers_out
8943 to reflect above changes. [Petr Lampa]
8945 *) Fixed the determination of whether or not we should make the
8946 connection persistent for all of the cases where some other part
8947 of the server has already indicated that we should not. Also
8948 improved the ordering of the test so that chunked encoding will
8949 be set whenever it is desired instead of only when KeepAlive
8950 is enabled. Added persistent connection capability for most error
8951 responses (those that do not indicate a bad input stream) when
8952 accessed by an HTTP/1.1 client. [Roy Fielding]
8954 *) Added missing timeouts for sending header fields, error responses,
8955 and the last chunk of chunked encoding, each of which could have
8956 resulted in a process being stuck in write forever. Using soft_timeout
8957 requires that the sender check for an aborted connection rather than
8958 continuing after an EINTR. Timeouts that used to be initiated before
8959 send_http_header (and never killed) are now initiated only within or
8960 around the routines that actually do the sending, and not allowed to
8961 propagate above the caller. [Roy Fielding]
8963 *) mod_auth_anon required an @ or a . in the email address, not both.
8966 *) per_dir_defaults weren't set correctly until directory_walk for
8967 name-based vhosts. This fixes an obscure bug with the wrong config
8968 info being used for vhosts that share the same ip as the server.
8971 *) Improved generation of modules/Makefile to be more generic for
8972 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8974 *) Generate makefile dependency for Configuration based on the actual
8975 name given when running the Configure process. [Dean Gaudet]
8977 *) Fixed problem with vhost error log not being set prior to
8978 initializing virtual hosts. [Dean Gaudet]
8980 *) Fixed infinite loop when a trailing slash is included after a type map
8981 file URL (extra path info). [Petr Lampa]
8983 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8985 *) Add documentation for DNS issues (reliability and security), and try
8986 to explain the virtual host matching process. [Dean Gaudet]
8988 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8989 fails while parsing the configuration file. [Dean Gaudet]
8991 *) Improved calls to setsockopt. [Roy Fielding]
8993 *) Negotiation changes: Don't output empty content-type in variant list;
8994 Output charset in variant list; Return sooner from handle_multi() if
8995 no variants found; Add handling of '*' wildcard in Accept-Charset.
8996 [Petr Lampa and Paul Sutton]
8998 *) Fixed overlaying of request/sub-request notes and headers in
8999 mod_negotiation. [Dean Gaudet]
9001 *) If two variants' charset quality are equal and one is the default
9002 charset (iso-8859-1), then prefer the variant that was specifically
9003 listed in Accept-Charset instead of the default. [Petr Lampa]
9005 *) Memory allocation problem in push_array() -- it would corrupt memory
9006 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
9008 *) invoke_handler() doesn't handle mime arguments in content-type
9011 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
9014 *) Fixed problem with ErrorDocument not working for virtual hosts
9015 due to one of the performance changes in 1.2b7. [Dean Gaudet]
9017 *) Log an error message if we get a request header that is too long,
9018 since it may indicate a buffer overflow attack. [Marc Slemko]
9020 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
9021 not reject URLs without a double-slash, as per RFC2068 section 3.2.
9022 [Ken Coar] PR #146, #187

9028 [Garey Smiley] PR #59
9030 *) Fixed error message when resource is not found and URL contains
9031 path info. [Petr Lampa and Dean Gaudet] PR #40
9033 *) Fixed user and server confusion over what should be a virtual host
9034 and what is the main server, resulting in access to something
9035 other than the name defined in the virtualhost directive (but
9036 with the same IP address) failing. [Dean Gaudet]
9038 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
9039 AIX; improves the redirection stuff to enable the users to generally
9040 redirect to http, https, gopher and ftp; added TIME variable for
9041 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
9042 special patterns >STRING, <STRING and =STRING to RewriteCond, which
9043 can be used in conjunction with %{TIME} or other variables to create
9044 time-dependent rewriting rules. [Ralf S. Engelschall]
9046 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
9047 Module authors may need to adjust their code for proper cleanup to take
9048 place (that is, call note_cleanups_for_fd()). This change fixes problems
9049 with file descriptors being erroneously closed when the proxy module was
9050 in use. [Ben Laurie]
9052 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
9053 initgroups() to hose the group information needed for later
9054 comparisons. [Randy Terbush]
9056 *) Remove unnecessary call to va_end() in create_argv() which
9057 caused a SEGV on some systems.
9059 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
9062 *) Clear memory allocated for listeners. [Randy Terbush]
9064 *) Improved handling of IP address as a virtualhost address and
9065 introduced "_default_" as a synonym for the default vhost config.
9066 [Dean Gaudet] PR #212
9068 Changes with Apache 1.2b7
9070 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
9072 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
9074 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
9075 - replace protocol response numbers with symbols
9076 - save variant-list into main request notes
9077 - free allocated memory from subrequests
9078 - merge notes, headers_out and err_headers_out
9080 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
9081 "HTTP/#.# ###*" to be more lenient about what we accept.
9084 *) more proxy FTP bug fixes:
9085 - Changed send_dir() to remove user/passwd from displayed URL.
9086 - Changed login error messages to be more descriptive.
9087 - remove setting of SO_DEBUG socket option
9088 - Make ftp_getrc() more lenient about multiline responses,
9089 specifically, 230 responses which don't have continuation 230-
9090 on each line). These seem to be all NT FTP servers, and while
9091 perhaps questionable, they appear to be legal by RFC 959.
9092 - Add missing kill_timeout() after transfer to user completes.
9095 *) Fixed problem where a busy server could hang when restarting
9096 after being sent a SIGHUP due to child processes not exiting.
9099 *) Modify mod_include escaping so a '\' only signifies an escaped
9100 character if the next character is one that needs
9101 escaping. [Ben Laurie]
9103 *) Eliminated possible infinite loop in mod_imap when relative URLs are
9104 used with a 'base' directive that does not have a '/' in it.
9105 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
9107 *) Reduced the default timeout from 1200 seconds to 300, and the
9108 one in the sample configfile from 400 to 300. [Marc Slemko]
9110 *) Stop vbprintf from crashing if given a NULL string pointer;
9111 print (null) instead. [Ken Coar]
9113 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
9114 [Marc Slemko and Roy Fielding]
9116 *) Fixed problem with mod_cgi-generated internal redirects trying to
9117 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9119 *) Reduced timeout on lingering close, removed possibility of a blocked
9120 read causing the child to hang, and stopped logging of errors if
9121 the socket is not connected (reset by client). [Roy Fielding]
9123 *) Rearranged main child loop to remove duplication of code in
9124 select/accept and keep-alive requests, fixed several bugs regarding
9125 checking scoreboard_image for exit indication and failure to
9126 account for all success conditions and trap all error conditions,
9127 prevented multiple flushes before closing the socket; close the entire
9128 socket buffer instead of just one descriptor, prevent logging of
9129 EPROTO and ECONNABORTED on platforms where supported, and generally
9130 improved readability. [Roy Fielding]
9132 *) Extensive performance improvements. Cleaned up inefficient use of
9133 auto initializers, multiple is_matchexp calls on a static string,
9134 and excessive merging of response_code_strings. [Dean Gaudet]
9136 *) Added double-buffering to mod_include to improve performance on
9137 server-side includes. [Marc Slemko]
9139 *) Several fixes for suexec wrapper. [Randy Terbush]
9140 - Make wrapper work for files on NFS filesystem.
9141 - Fix portability problem of MAXPATHLEN.
9142 - Fix array overrun problem in clean_env().
9143 - Fix allocation of PATH environment variable
9145 *) Removed extraneous blank line is description of mod_status chars.
9148 *) Logging of errors from the call_exec routine simply went nowhere,
9149 since the logfile fd has been closed, so now we send them to stderr.
9150 [Harald T. Alvestrand]
9152 *) Fixed core dump when DocumentRoot is a CGI.
9153 [Ben Laurie, reported by geddis@tesserae.com]
9155 *) Fixed potential file descriptor leak in mod_asis; updated it and
9156 http_core to use pfopen/pfclose instead of fopen/fclose.
9157 [Randy Terbush and Roy Fielding]
9159 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9160 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9161 [Dean Gaudet and Ken Coar]
9163 *) Return a 302 response code to the client when sending a redirect
9164 due to a missing trailing '/' on a directory instead of a 301; now
9165 it is cacheable. [Markus Gyger]
9167 *) Fix condition where, if a bad directive occurs in .htaccess, and
9168 sub_request() goes first to this directory, then log_reason() will
9169 SIGSEGV because it doesn't have initialized r->per_dir_config.
9170 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9172 *) Fix handling of lang_index in is_variant_better(). This was
9173 causing problems which resulted in the server sending the
9174 wrong language document in some cases. [Petr Lampa]
9176 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9177 the clean environment on some systems.
9179 *) Tweak byteserving code (e.g. serving PDF files) to work around
9180 bugs in Netscape Navigator and Microsoft Internet Explorer.
9181 Emit Content-Length header when sending multipart/byteranges.
9184 *) Port to HI-UX/WE2. [Nick Maclaren]
9186 *) Port to HP MPE operating system for HP 3000 machines
9187 [Mark Bixby <markb@cccd.edu>]
9189 *) Fixed bug which caused a segmentation fault if only one argument
9190 given to RLimit* directives. [Ed Korthof]
9192 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9194 *) Improved buffered output to the client by delaying the flush decision
9195 until the BUFF code is actually about to read the next request.
9196 This fixes a problem introduced in 1.2b5 with clients that send
9197 an extra CRLF after a POST request. Also improved chunked output
9198 performance by combining writes using writev() and removing as
9199 many bflush() calls as possible. NOTE: Platforms without writev()
9200 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9201 or Configure, unless we have already done so. [Dean Gaudet]
9203 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9205 *) Fixed mod_info output corruption bug introduced by buffer overflow
9206 fixes. [Dean Gaudet]
9208 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9209 for the special case of a 304 response. [Paul Sutton]
9211 *) Improved handling of TRACE method by bypassing normal method handling
9212 and header parsing routines; fixed Allow response to always allow TRACE.
9215 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9217 *) Cleaned-up some of the generated HTML. [Ken Coar]
9219 Changes with Apache 1.2b6
9221 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9223 *) Fix typo introduced in fix for potential infinite loop around
9224 accept() in child_main(). This change caused the rev to 1.2b6.
9225 1.2b5 was never a public beta.
9227 Changes with Apache 1.2b5
9229 *) Change KeepAlive semantics (On|Off instead of a number), add
9230 MaxKeepAliveRequests directive. [Alexei Kosut]
9232 *) Various NeXT compilation patches, as well as a change in
9233 regex/regcomp.c since that file also used a NEXT define.
9236 *) Allow * to terminate the end of a directory match in mod_dir.
9237 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9239 *) Don't call can_exec() if suexec_enabled. Calling this requires
9240 scripts executed by the suexec wrapper to be world executable, which
9241 defeats one of the advantages of running the wrapper. [Randy Terbush]
9243 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9246 *) Migration from sprintf() to snprintf() to avoid buffer
9247 overflows. [Marc Slemko]
9249 *) Provide portable snprintf() implementation (ap_snprintf)
9250 as well as *cvt family. [Jim Jagielski]
9252 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9255 *) Remove mod_fastcgi.c from the distribution. This module appears
9256 to be maintained more through the Open Market channels and should
9257 continue to be easily available at http://www.fastcgi.com/
9259 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9260 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9262 *) mod_info assumed that the config files were relative to ServerRoot.
9265 *) CGI scripts called as an error document resulting from failed
9266 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9268 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9271 *) Properly check errno to prevent display of a directory index
9272 when server receives a long enough URL to confuse stat().
9275 *) Several security enhancements to suexec wrapper. It is _highly_
9276 recommended that previously installed versions of the wrapper
9277 be replaced with this version. [Randy Terbush, Jason Dour]
9279 - ~user execution now properly restricted to ~user's home
9280 directory and below.
9281 - execution restricted to UID/GID > 100
9282 - restrict passed environment to known variables
9283 - call setgid() before initgroups() (portability fix)
9284 - remove use of setenv() (portability fix)
9286 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9288 *) Add access control via environment variables. [Ben Laurie]
9290 *) Add rflush() function. [Alexei Kosut]
9292 *) remove duplicate pcalloc() call in new_connection().
9294 *) Fix incorrect comparison which could allow number of children =
9295 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9296 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9298 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9299 AIX PS/2, CONVEXOS. [Jim Jagielski]
9301 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9302 It's more portable. [Martin Kraemer]
9304 *) Replace references to make in Makefile.tmpl with $(MAKE).
9307 *) Add ProxyBlock directive w/IP address caching. Add IP address
9308 caching to NoCache directive as well. ProxyBlock works with all
9309 handlers; NoCache now also works with FTP for anonymous logins.
9310 Still more code cleanup. [Chuck Murcko]
9312 *) Add "header parse" API hook [Ben Laurie]
9314 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9316 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9318 *) Correctly allow access and auth directives in <Files> sections in
9319 server config files. [Alexei Kosut]
9321 *) Fix bug with ServerPath that could cause certain files to be not
9322 found by the server. [Alexei Kosut]
9324 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9325 double-quote from text and so that it properly checks for unsupported
9326 status codes using the new index_of_response interface. [Roy Fielding]
9328 *) Multiple fixes to the lingering_close code in order to avoid being
9329 interrupted by a stray timeout, to avoid lingering on a connection
9330 that has already been aborted or never really existed, to ensure that
9331 we stop lingering as soon as any error condition is received, and to
9332 prevent being stuck indefinitely if the read blocks. Also improves
9333 reporting of error conditions. [Marc Slemko and Roy Fielding]
9335 *) Fixed initialization of parameter structure for sigaction.
9336 [mgyger@itr.ch, Adrian Filipi-Martin]
9338 *) Fixed reinitializing the parameters before each call to accept and
9339 select, and removed potential for infinite loop in accept.
9340 [Roy Fielding, after useful PR from adrian@virginia.edu]
9342 *) Fixed condition where, if a child fails to fork, the scoreboard would
9343 continue to say SERVER_STARTING forever. Eventually, the main process
9344 would refuse to start new children because count_idle_servers() will
9345 count those SERVER_STARTING entries and will always report that there
9346 are enough idle servers. [Phillip Vandry]
9348 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9349 Avoided calling bflush() when the client is pipelining requests.
9350 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9352 *) Added description of "." mode in server-status [Jim Jagielski]
9354 Changes with Apache 1.2b4
9356 *) Fix possible race condition in accept_mutex_init() that
9357 could leave a small security hole open allowing files to be
9358 overwritten in cases where the server UID has write permissions.
9361 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9363 *) Fix portablity problem in util_script where ARG_MAX may not be
9364 defined for some systems.
9366 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9369 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9370 style magic #! token for better script portability. [Garey Smiley]
9372 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9373 execution for ~userdir CGI. [Jason Dour]
9375 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9377 *) Fix month off by one in suexec wrapper logging.
9379 Changes with Apache 1.2b3:
9381 *) Fix error in mod_cgi which could cause resources not to be properly
9382 freed, or worse. [Dean Gaudet]
9384 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9386 *) Add set_flag_slot() at the request of Dirk and others.
9389 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9391 *) Add changes to improve the error message given for invalid
9392 ServerName parameters. [Dirk vanGulik]
9394 *) Add "Authoritative" directive for Auth modules that don't
9395 currently have it. This gives admin control to assign authoritative
9396 control to an authentication scheme and allow "fall through" for
9397 those authentication modules that aren't "Authoritative" thereby
9398 allowing multiple authentication mechanisms to be chained.
9401 *) Remove requirement for ResourceConfig/AccessConfig if not using
9402 the three config file layout. [Randy Terbush]
9404 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9406 *) Changes to suexec wrapper to fix the following problems:
9407 1. symlinked homedirs will kill ~userdirs.
9408 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9409 3. CGI command lines paramters problems
9410 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9411 [Randy Terbush, Jason Dour]
9413 *) Change create_argv() to accept variable arguments. This fixes
9414 a problem where arguments were not getting passed to the CGI via
9415 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9417 *) Collapse multiple slashes in path URLs to properly apply
9418 handlers defined by <Location>. [Alexei Kosut]
9420 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9422 *) Improve the accuracy of request duration timings by setting
9423 r->request_time in read_request_line() instead of read_request().
9426 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9427 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9429 *) Add the ability to pass different Makefile.tmpl files to Configure
9430 using the -make flag. [Rob Hartill]
9432 *) Fix coredump triggered when sending a SIGHUP to the server caused
9433 by an assertion failure, in turn caused by an uninitialised field in a
9437 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9438 PATH_INFO from previous versions of Apache (in certain situations,
9439 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9440 [later removed in 1.2b11]
9442 *) Add rwrite() function to API to allow for sending strings of
9443 arbitrary length. [Doug MacEachern]
9445 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9447 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9448 NeXT. [Jim Jagielski]
9450 *) Removed recent modification to promote the status code on internal
9451 redirects, since the correct fix was to change the default log format
9452 in mod_log_config so that it outputs the original status. [Rob Hartill]
9454 Changes with Apache 1.2b2:
9456 *) Update set_signals() to use sigaction() for setting handlers.
9457 This appears to fix a re-entrant problem in the seg_fault()
9458 bus_error() handlers. [Randy Terbush]
9460 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9462 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9464 *) proxy_http.c bugfixes: [Chuck Murcko]
9465 1) fixes possible NULL pointer reference w/NoCache
9466 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9467 host would cache nothing if it was in the local domain,
9468 and the local domain was in the NoCache list)
9469 3) Adds Host: header when not available
9470 4) Some code cleanup and clarification
9472 *) mod_include.c bugfixes:
9473 1) Fixed an ommission that caused include variables to not
9474 be parsed in config errmsg directives [Howard Fear]
9475 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9476 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9477 4) Allow backslash-escaping to all quoted text
9478 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9479 5) Pass variable to command line if not set in XSSI's env
9482 *) Fix infinite loop when processing Content-language lines in
9483 type-map files. [Alexei Kosut]
9485 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9487 *) Fixed problem in set_[user|group] that prevented CGI execution
9488 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9490 *) Added PORTING information file. [Jim Jagielski]
9492 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9494 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9496 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9497 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9499 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9500 which caused problems of systems where socket s_addr is >32bits.
9502 *) Added comment to explain (r->chunked = 1) side-effect in
9503 http_protocol.c [Roy Fielding]
9505 *) Replaced use of index() in mod_expires.c with more appropriate
9506 and portable isdigit() test. [Ben Laurie]
9508 *) Updated Configure for ...
9509 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9510 *-dg-dgux* (bad pattern match)
9511 QNX (DEF_WANTHSREGEX=yes)
9512 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9515 and added some user diagnostic info. [Ben Laurie]
9517 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9518 for better portability. [Jim Jagielski]
9520 *) Updated helpers/GuessOS for ...
9521 SCO 5 (recognize minor releases)
9522 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9523 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9524 IRIX64 (-sgi-irix64)
9525 ULTRIX (-unknown-ultrix)
9526 SINIX (-whatever-sysv4)
9527 NCR Unix (-ncr-sysv4)
9528 and fixed something in helpers/PrintPath [Ben Laurie]
9530 Changes with Apache 1.2b1
9532 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9534 Changes with Apache 1.1.1
9536 *) Fixed bug where Cookie module would make two entries in the
9537 logfile for each access [Mark Cox]
9539 *) Fixed bug where Redirect in .htaccess files would cause memory
9540 leak. [Nathan Neulinger]
9542 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9544 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9546 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9548 Changes with Apache 1.1.0
9550 *) Bring NeXT support up to date. [Takaaki Matsumoto]

9554 *) Make virtual hosts default to main server keepalive parameters.
9555 [Alexei Kosut, Ben Laurie]
9557 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9559 *) Fix missing address family for connect, also remove unreachable statement
9560 in mod_proxy. [Ben Laurie]
9562 *) mod_env now turned on by default in Configuration.tmpl.
9564 *) Bugs which were fixed:
9565 a) yet more mod_proxy bugs [Ben Laurie]
9566 b) CGI works again with inetd [Alexei Kosut]
9567 c) Leading colons were stripped from passwords [osm@interguide.com]
9568 d) Another fix to multi-method Limit problem [jk@tools.de]
9570 Changes with Apache 1.1b4
9572 *) r->bytes_sent variable restored. [Robert Thau]
9574 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9576 *) More possibly unsecure programs removed from the support directory.
9578 *) More mod_auth_msql authentication improvements.
9580 *) VirtualHosts based on Host: headers no longer conflict with the
9583 *) OS/2 compatibility enhancements. [Gary Smiley]
9585 *) POST now allowed to directory index CGI scripts.
9587 *) Actions now work with files of the default type.
9589 *) Bugs which were fixed:
9590 a) more mod_proxy bugs
9591 b) early termination of inetd requests
9592 c) compile warnings on several systems
9593 d) problems when scripts stop reading output early
9595 Changes with Apache 1.1b3
9597 *) Much of cgi-bin and all of cgi-src has been removed, due to
9598 various security holes found and that we could no longer support
9601 *) The "Set-Cookie" header is now special-cased to not merge multiple
9602 instances, since certain popular browsers can not handle multiple
9603 Set-Cookie instructions in a single header. [Paul Sutton]
9605 *) rprintf() added to buffer code, occurrences of sprintf removed.
9608 *) CONNECT method for proxy module, which means tunneling SSL should work.
9609 (No crypto needed) Also a NoCache config directive.
9611 *) Several API additions: pstrndup(), table_unset() and get_token()
9612 functions now available to modules.
9614 *) mod_imap fixups, in particular Location: headers are now complete
9617 *) New "info" module which reports on installed module set through a
9618 special URL, a la mod_status.
9620 *) "ServerPath" directive added - allows for graceful transition
9621 for Host:-header-based virtual hosts.
9623 *) Anonymous authentication module improvements.
9625 *) MSQL authentication module improvements.
9627 *) Status module design improved - output now table-based. [Ben Laurie]
9629 *) htdigest utility included for use with digest authentication
9632 *) mod_negotiation: Accept values with wildcards to be treated with
9633 less priority than those without wildcards at the same quality
9634 value. [Alexei Kosut]
9636 *) Bugs which were fixed:
9637 a) numerous mod_proxy bugs
9638 b) CGI early-termination bug [Ben Laurie]
9639 c) Keepalives not working with virtual hosts
9640 d) RefererIgnore problems
9641 e) closing fd's twice in mod_include (causing core dumps on

9655 Changes with Apache 1.0.3
9657 *) Internal redirects which occur in mod_dir.c now preserve the
9658 query portion of a request (the bit after the question mark).
9661 *) Escape active characters '<', '>' and '&' in html output in
9662 directory listings, error messages and redirection links.
9665 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9667 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9670 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9672 *) Reset timeout timer after each successful fwrite() to the network.
9673 This patch adds a reset_timeout() procedure that is called by
9674 send_fd() to reset the timeout ever time data is written to the net.
9677 *) timeout() signal handler now checks for SIGPIPE and reports
9678 lost connections in a more user friendly way. [Rob Hartill]
9680 *) Location of the "scoreboard" file which used to live in /tmp is
9681 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9682 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9684 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9686 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9687 which caused a SEGV with cookies enabled
9689 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9692 *) Log the UNIX textual error returned by some system calls, in
9693 particular errors from accept() [David Robinson]
9695 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9697 Changes with Apache 1.0.2
9699 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9700 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9702 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9705 *) past changes to http_config.c to only use the
9706 setrlimit function on systems defining RLIMIT_NOFILE
9707 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9708 for SUNOS and prototypes the needed functions.
9710 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9713 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9715 *) Merge multiple headers from CGI scripts instead of taking last
9716 one. [David Robinson]
9718 *) Add support for SCO 5. [Ben Laurie]
9720 Changes with Apache 1.0.1
9722 *) Silence mod_log_referer and mod_log_agent if not configured
9725 *) Recursive includes can occur if the client supplies PATH_INFO data
9726 and the server provider uses relative links; as file.html
9727 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9729 *) The replacement for initgroups() did not call {set,end}grent(). This
9730 had two implications: if anything else used getgrent(), then
9731 initgroups() would fail, and it was consuming a file descriptor.
9734 *) On heavily loaded servers it was possible for the scoreboard to get
9735 out of sync with reality, as a result of a race condition.
9736 The observed symptoms are far more Apaches running than should
9737 be, and heavy system loads, generally followed by catastrophic
9738 system failure. [Ben Laurie]
9740 *) Fix typo in license. [David Robinson]
9742 Changes with Apache 1.0.0 23 Nov 1995
9744 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9746 Changes with Apache 0.8.16 05 Nov 1995
9748 *) New man page for 'httpd' added to support directory [David Robinson]
9750 *) .htgroup files can have more than one line giving members for a
9751 given group (each must have the group name in front), for NCSA
9752 back-compatibility [Robert Thau]
9754 *) Mutual exclusion around accept() is on by default for SVR4 systems
9755 generally, since they generally can't handle multiple processes in
9756 accept() on the same socket. This should cure flaky behavior on
9757 a lot of those systems. [David Robinson]
9759 *) AddType, AddEncoding, and AddLanguage directives take multiple
9760 extensions on a single command line [David Robinson]
9762 *) UserDir can be disabled for a given virtual host by saying
9763 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9764 that this didn't work. [David Robinson]
9766 *) Compiles on QNX [Ben Laurie]
9768 *) Corrected parsing of ctime time format [David Robinson]
9770 *) httpd does a perror() before exiting if it can't log its pid
9771 to the PidFile, to make diagnosing the error a bit easier.
9774 *) <!--#include file="..."--> can no longer include files in the
9775 parent directory, for NCSA back-compatibility. [David Robinson]
9777 *) '~' is *not* escaped in URIs generated for directory listings
9780 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9782 *) Fixed bug involving handling URIs with escaped %-characters
9783 in redirects [David Robinson]
9785 Changes with Apache 0.8.15 14 Oct 1995
9787 *) Switched to new, simpler license
9789 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9791 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9793 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9795 *) Correctly handles internal redirects to files with names containing '%'
9798 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9800 *) Use geteuid() rather than getuid() to see if we have root privilege,
9801 so that server correctly resets privilege if run setuid root. [Andrew
9804 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9807 *) Fix relative URLs in imagemap files [Randy Terbush]
9809 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9812 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9813 entries all name the same one. [David Robinson]
9815 *) Fix directory listings with filenames containing unusual characters
9818 *) Better URI-escaping for generated URIs in directories with filenames
9819 containing unusual characters [Ben Laurie]
9821 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9823 *) Unblock alarms on error return from spawn_child() [David Robinson]
9825 *) Sample Config files have extra note for SCO users [Ben Laurie]
9827 *) Configuration has note for HP-UX users [Rob Hartill]
9829 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9831 *) Nuked bogus #define in httpd.h [David Robinson]
9833 *) Better test for whether a system has setrlimit() [David Robinson]
9835 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9837 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9840 Changes with Apache 0.8.14 19 Sep 1995
9842 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9844 *) AddDescription works (better) [Ben Laurie]
9846 *) Leaves an intelligible error diagnostic when it can't set group
9847 privileges on standalone startup [Andrew Wilson]
9849 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9850 that machine, which claims to be BSD but does not support RLIMIT.
9853 *) gcc -Wall no longer complains about an unused variable when util.c
9854 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9856 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9858 Changes with Apache 0.8.13 07 Sep 1995
9860 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9862 *) Have built-in imagemap code recognize & honor Point directive [James
9865 *) Generate cleaner directory listings in directories with a mix of
9866 long and short filenames [Rob Hartill]
9868 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9870 *) Properly default ServerName for virtual servers [Robert Thau]
9872 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9873 Paul Richards and a cast of thousands...]
9875 *) On self-identified BSD systems (we don't try to guess any more),
9876 allocate a few extra file descriptors per virtual host with setrlimit,
9877 if we can, to avoid running out. [Randy Terbush]
9879 *) Write 22-character lock file name into buffer with enough space
9880 on startup [Konstantin Olchanski]
9882 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9885 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9887 *) Suppress -Wall warning by initializing variable in negotiation code
9888 [Tobias Weingartner]
9890 Changes with Apache 0.8.12 31 Aug 1995
9892 *) Doesn't pause three seconds after including a CGI script which is
9893 too slow to die off (this is done by not even trying to kill off
9894 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9895 after the entire document has been processed). [Robert Thau]
9897 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9899 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9901 *) Allows .htaccess files to override <Directory> sections naming the
9902 same directory [David Robinson]
9904 *) Removed an efficiency hack in sub_req_lookup_uri which was
9905 causing certain extremely marginal cases (e.g., ScriptAlias of a
9906 *particular* index.html file) to fail. [David Robinson]
9908 *) Doesn't log an error when the requested URI requires
9909 authentication, but no auth header line was supplied by the
9910 client; this is a normal condition (the client doesn't no auth is
9911 needed here yet). [Robert Thau]
9913 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9915 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9917 *) RFC931 code no longer passes out name of prior clients on current
9918 requests if the current request came from a server that doesn't
9919 do RFC931. [David Robinson]
9921 *) Configuration script accepts "Module" lines with trailing whitespace.
9924 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9926 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9928 Changes with Apache 0.8.11 24 Aug 1995
9930 *) Wildcard <Directory> specifications work. [Robert Thau]
9932 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9934 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9935 the file being requested itself, in addition to the directories leading
9936 up to it. [Robert Thau]
9938 *) Logs access failures due to symlink checks or invalid client address
9939 in the error log [Roy Fielding, Robert Thau]
9941 *) Symlink checks deal correctly with systems where lstat of
9942 "/path/to/some/link/" follows the link. [Thau, Fielding]
9944 *) Doesn't reset DirectoryIndex to 'index.html' when
9945 other directory options are set in a .htaccess file. [Robert Thau]
9947 *) Clarified init code and nuked bogus warning in mod_access.c
9950 *) Corrected several directives in sample srm.conf
9951 --- includes corrections to directory indexing icon-related directives
9952 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9953 icons for encodings right, and turning on AddEncoding by default).
9956 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9959 *) INSTALL & README mention "contributed modules" directory [Brian
9962 *) Fixed English in the license language... "for for" --> "for".
9965 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9966 mod_alias.c, merging it almost completely with handling of Alias, and
9967 adding a 'notes' field to the request_rec which allows the CGI module
9968 to discover whether the Alias module has put this request through
9969 ScriptAlias (which it needs to know for back-compatibility, as the old
9970 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9973 Changes with Apache 0.8.10 18 Aug 1995
9975 *) AllowOverride applies to the named directory, and not just
9976 subdirectories. [David Robinson]
9978 *) Do locking for accept() exclusion (on systems that need it)
9979 using a special file created for the purpose in /usr/tmp, and
9980 not the error log; using the error log causes real problems
9981 if it's NFS-mounted; this is known to be the cause of a whole
9982 lot of "server hang" problems with Solaris. [David Robinson;
9983 thanks to Merten Schumann for help diagnosing the problem].
9985 Changes with Apache 0.8.9 12 Aug 1995
9987 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9989 *) Nested includes see environment variables of the including document,
9990 for NCSA bug-compatibility (some sites have standard footer includes
9991 which try to print out the last-modified date). [Eric Hagberg/Robert
9994 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9995 URI as a CGI script, even if it would have been treated as something
9996 else if requested directly, for NCSA back-compatibility. (Note that
9997 this means that people who know the name of the script can see the
9998 code just by asking for it). [Robert Thau]
10000 *) New version of dbmmanage script included in support directory as
10003 *) Check if scoreboard file couldn't be opened, and say so, rather
10004 then going insane [David Robinson]
10006 *) POST to CGI works on A/UX [Jim Jagielski]
10008 *) AddIcon and AddAlt commands work properly [Rob Hartill]
10010 *) NCSA server push works properly --- the Arena bug compatibility
10011 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
10012 if you still want the workaround). [Rob Hartill]
10014 *) If client didn't submit any Accept-encodings, ignore encodings in
10015 content negotiation. (NB this will all have to be reworked anyway
10016 for the new HTTP draft). [Florent Guillaume]
10018 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
10020 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
10022 *) Give Redirect priority over Alias, for NCSA bug compatibility
10025 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
10026 paralleling earlier bug fix for CGI [David Robinson]
10028 *) If DBM auth is improperly configured, report a server error and don't
10031 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
10032 it seems to work well enough without it (even in a 10 hits/sec
10033 workout), and the overhead for the locking under A/UX is
10034 alarmingly high (though it is very low on other systems).
10035 [Eric Hagberg, Jim Jagielski]
10037 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
10039 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
10040 Behlendorf/Eric Hagberg]
10042 *) More improvements to default Configuration for A/UX [Jim Jagielski]
10044 *) Compiles clean on NEXT [Rob Hartill]
10046 *) Compiles clean on SGI [Robert Thau]
10048 Changes with Apache 0.8.8 08 Aug 1995
10050 *) SunOS library prototypes now never included unless explicitly
10051 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
10052 people using GNU libc on SunOS are screwed by prototypes for the
10055 (Those who wish to compile clean with gcc -Wall on a standard
10056 SunOS setup need the prototypes, and may obtain them using
10057 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
10058 with nonstandard libraries are presumably competent to make their
10061 *) Strips trailing '/' characters off both args to the Alias command,
10062 to make 'Alias /foo/ /bar/' work.
10064 Changes with Apache 0.8.7 03 Aug 1995
10066 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
10067 [reported by David Robinson]
10069 *) Compiles clean on OSF/1 [David Robinson]
10071 *) Added some of the more recent significant changes (AddLanguage stuff,
10072 experimental LogFormat support) to CHANGES file in distribution root
10075 Changes with Apache 0.8.6 02 Aug 1995
10077 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10078 (If you actually wanted a conditional GET which bypassed the cache, you
10079 couldn't get it). [Reported by Roy Fielding]
10081 *) Properly terminate headers on '304 Not Modified' replies to conditional
10082 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10083 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10085 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10087 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10088 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10089 and older versions don't set the __SUNPRO_C preprocessor variable). On
10090 all other systems, these are never used anyway. [Reported by Mark Cox].
10092 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10094 Changes with Apache 0.8.5 01 Aug 1995
10096 *) Added last-minute configurable log experiment, as optional module
10098 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10099 properly. (One-line fix to http_protocol.c).
10101 *) Work around bogus behavior when reloading from Netscape.
10102 It's Netscape's bug --- for some reason they expect a request with
10103 If-modified-since: to not function as a conditional GET if it also
10104 comes with Pragma: no-cache, which is way out of line with the HTTP
10105 spec (according to Roy Fielding, the redactor).
10107 *) Added parameter to set maximum number of server processes.
10109 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10112 *) IdentityCheck bugfix [Chuck Murcko].
10114 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10116 *) More sample config file corrections; add extension to AddType for
10117 *.asis, move AddType generic description to its proper place, and
10118 fix miscellaneous typos. [ Alexei Kosut ]
10120 *) Deleted the *other* reference to the regents from the Berkeley
10121 legal disclaimer (everyplace).
10123 *) Nuked Shambhala name from src/README; had already cleaned it out
10124 of everywhere else.
10126 Changes with Apache 0.8.4
10128 *) Changes to server-pool management parms --- renamed current
10129 StartServers to MinSpareServers, created separate StartServers
10130 parameter which means what it says, and renamed MaxServers to
10131 MaxSpareServers (though the old name still works, for NCSA 1.4
10132 back-compatibility). The old names were generally regarded as
10133 too confusing. Also altered "docs" in sample config files.
10135 *) More improvements to default config files ---
10136 sample directives (commented out) for XBitHack, BindAddress,
10137 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10138 defaults, AddTypes for send-as-is and imagemap magic types, and
10139 improvements to samples for DirectoryIndex [Alexei Kosut]
10141 *) Yet more improvements to default config files --- changes to
10142 Alexei's sample AddLanguage directives, and sample LanguagePriority
10143 [ Florent Guillaume ]
10145 *) Set config file locations properly if not set in httpd.conf
10148 *) Don't escape URIs in internal redirects multiple times; don't
10149 do that when translating PATH_INFO to PATH_TRANSLATED either.
10152 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10154 Changes with Apache 0.8.3
10156 *) Edited distribution README to *briefly* summarize installation
10157 procedures, and give a pointer to the INSTALL file in the src/
10160 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10161 recent NCSA distributions.
10163 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10164 exist for the same directory, use both and don't segfault. [Reported
10167 *) Proper makefile dependencies [David Robinson]
10169 *) Note (re)starts in error log --- reported by Rob Hartill.
10171 *) Only call no2slash() after get_path_info() has been done, to
10172 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10173 reported by Andrew Wilson, though this one is probably a real bug]
10175 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10176 dump core when Referer is not supplied. [Randy Terbush]
10178 *) Lightly edited sample config files to refer people to our documentation
10179 instead of NCSA's, and to list Rob McCool as *original* author (also
10180 deleted his old, and no doubt non-functional email address). Would be
10181 nice to have examples of new features...
10183 Changes with Apache 0.8.2 19 Jul 1995
10185 *) Added AddLanuage code [Florent Guillaume]
10187 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10189 *) All sorts of problems when MultiViews finds a directory. It would
10190 be nice if mod_dir.c was robust enough to handle that, but for now,
10191 just punt. [reported by Brian Behlendorf]
10193 *) Wait for all children on restart, to make sure that the old socket
10194 is gone and we can reopen it. [reported by Randy Terbush]
10196 *) Imagemap module is enabled in default Configuration
10198 *) RefererLog and UserAgentLog modules properly default the logfile
10201 *) Mark Cox's mod_cookies added to the distribution as an optional
10202 module (commented out in the default Configuration, and noted as
10203 an experiment, along with mod_dld). [Mark Cox]
10205 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10207 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10209 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10211 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10214 Changes with Apache 0.8.1
10216 *) New imagemap module [Randy Terbush]
10218 *) Replacement referer log module with NCSA-compatible RefererIgnore
10219 [Matthew Gray again]
10221 *) Don't mung directory listings with very long filenames.
10222 [Florent Guillaume]
10224 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10226 *) New config script. See INSTALL for info. [Robert Thau]
10228 *) Scoreboard mechanism for regulating the number of extant server
10229 processes. MaxServers and StartServers defaults are the same as
10230 for NCSA, but the meanings are slightly different. (Actually,
10231 I should probably lower the MaxServers default to 10).
10233 Before asking for a new connection, each server process checks
10234 the number of other servers which are also waiting for a
10235 connection. If there are more than MaxServers, it quietly dies
10236 off. Conversely, every second, the root, or caretaker, process
10237 looks to see how many servers are waiting for a new connection;
10238 if there are fewer than StartServers, it starts a new one. This
10239 does not depend on the number of server processes already extant.
10240 The accounting is arranged through a "scoreboard" file, named
10241 /tmp/htstatus.*, on which each process has an independent file
10242 descriptor (they need to seek without interference).
10244 The end effect is that MaxServers is the maximum number of
10245 servers on an *inactive* server machine, but more will be forked
10246 off to handle unusually heavy loads (or unusually slow clients);
10247 these will die off when they are no longer needed --- without
10248 reverting to the overhead of full forking operation. There is a
10249 hard maximum of 150 server processes compiled in, largely to
10250 avoid forking out of control and dragging the machine down.
10251 (This is arguably too high).
10253 In my server endurance tests, this mechanism did not appear to
10254 impose any significant overhead, even after I forced it to put the
10255 scoreboard file on a normal filesystem (which might have more
10256 overhead than tmpfs). [Robert Thau]
10258 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10261 *) Read .htaccess files even in directory with <Directory> section.
10262 (Former incompatibility noted on mailing list, now fixed). [Robert
10265 *) "HEAD /" gives the client a "Bad Request" error message, rather
10266 than trying to send no body *and* no headers. [Cliff Skolnick].
10268 *) Don't produce double error reports for some very obscure cases
10269 mainly involving auth configuration (the "all modules decline to
10270 handle" case which is a sure sign of a server bug in most cases,
10271 but also happens when authentication is badly misconfigured).
10274 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10275 it's *for*, and this sort of thing really shouldn't be cluttering
10276 up the Makefile). [Robert Thau]
10278 *) Incidental code cleanups in http_main.c --- stop dragging
10279 sa_client around; just declare it where used. [Robert Thau]
10281 *) Another acc-related fix. (It doesn't like const char
10282 in some places...). [Mark Cox]
10284 Changes with Shambhala 0.6.1 13 Jul 1995
10286 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10287 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10289 *) Compiles clean with acc on SunOS [Paul Sutton]
10291 *) Reordered modules in modules.c so that Redirect takes priority
10292 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10293 believe it or not, he has an actual site with a ScriptAlias and
10294 a Redirect declared for the *exact same directory*. Even *my*
10295 compatibility fetish wouldn't motivate me to fix this if the fix
10296 required any effort, but it doesn't, so what the hey.
10298 *) Fixed to properly default several server_rec fields for virtual
10299 servers from the corresponding fields in the main server_rec.
10300 [Cliff Skolnick --- 'port' was a particular irritant].
10302 *) No longer kills off nph- child processes before they are
10303 finished sending output. [Matthew Gray]
10305 Changes with Shambhala 0.6.0 10 Jul 1995
10307 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10308 the connection to the client in an "aborted" state, but otherwise
10309 allow whatever handlers are running to clean up. hard_timeout()s
10310 abort the request in progress completely; anything not tied to some
10311 resource pool cleanup will leak. They're still around because I
10312 haven't yet come up with a more elegant way of handling
10313 timeouts when talking to something that isn't the client. The
10314 default_handler and the dir_handler now use soft timeouts, largely
10315 so I can test the feature. [Robert Thau]
10317 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10318 the case of log handlers dying prematurely is probably handled VERY
10319 gracelessly at this point, and if the logger stops reading input,
10320 the server will hang. (It is known to correctly restart the
10321 logging process on server restart; this is (should be!) going through
10322 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10323 script). [Robert Thau]
10325 *) asis files supported (new module). [Robert Thau]
10327 *) IdentityCheck code is compiled in, but has not been tested. (I
10328 don't know anyone who runs identd). [Robert Thau]
10330 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10331 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10333 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10335 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10336 as timeouts are not in scope. [Robert Thau]
10338 *) quoted-string args in config files now handled correctly (doesn't drop
10339 the last character). [Robert Thau; reported by Randy Terbush]
10341 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10342 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10344 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10345 default default type); the former default default behavior when all
10346 type-checkers defaulted had been a core dump. [Paul Sutton]
10348 *) Copy filenames out of the struct dirent when indexing
10349 directories. (On Linux, readdir() returns a pointer to the same
10350 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10352 Changes with Shambhala 0.5.3 [not released]
10354 *) Default response handler notes "file not found" in the error log,
10355 if the file was not found. [Cliff Skolnick].
10357 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10358 code no longer sets up bogus PATH_INFO which fakes out the directory
10359 handler). [Cliff Skolnick]
10361 Changes with Shambhala 0.5.2 06 Jul 1995
10363 *) Changes to http_main.c --- root server no longer plays silly
10364 games with SIGCHLD, and so now detects and replaces dying
10365 children. Child processes just die on SIGTERM, without taking
10366 the whole process group with them. Potential problem --- if any
10367 child process refuses to die, we hang in restart.
10368 MaxRequestsPerChild may still not work, but it certainly works
10369 better than it did before this! [Robert Thau]
10371 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10372 work (or work better, at least); over-long description lines
10373 properly terminated. [Mark Cox]
10375 *) http_request.c now calls unescape_url() more places where it
10376 should [Paul Sutton].
10378 *) More directory handling bugs (reported by Cox)
10379 Parent Directory link is now set correctly. [Robert Thau]
10381 Changes with Shambhala 0.5.1 04 Jul 1995
10383 *) Generalized cleanup interface in alloc.c --- any function can be
10384 registered with alloc.c as a cleanup for a resource pool;
10385 tracking of files and file descriptors has been reimplemented in
10386 terms of this interface, so I can give it some sort of a test.
10389 *) More changes in alloc.c --- new cleanup_for_exec() function,
10390 which tracks down and closes all file descriptors which have been
10391 registered with the alloc.c machinery before the server exec()s a
10392 child process for CGI or <!--#exec-->. CGI children now get
10393 started with exactly three file descriptors open. Hopefully,
10394 this cures the problem Rob H. was having with overly persistent
10395 CGI connections. [Robert Thau]
10397 *) Mutual exclusion around the accept() in child_main() --- this is
10398 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10399 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10400 This uses fcntl(F_SETLK,...) on the error log descriptor because
10401 flock() on that descriptor won't work on systems which have BSD
10402 flock() semantics, including (I think) Linux 1.3 and Solaris.
10404 This does work on SunOS (when the server is idle, only one
10405 process in the pool is waiting on accept()); it *ought* to work
10406 on the other systems. [Robert Thau]
10408 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10410 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10412 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10414 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10415 be unnecessary if I go to the revised timeout-handling scheme).
10418 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10419 string) even if none came in with the request. [Robert Thau]
10421 *) CHANGES file added to distribution ;-).
10423 Changes with Shambhala 0.4.5
10425 *) mod_dld --- early dynamic loading support [rst]
10426 *) Add wildcard content handlers for XBITHACK; default_hander now
10427 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10428 *) XBITHACK supported as a wildcard content-handler, and
10429 configurable at run-time (not just at compile time, as in the
10430 "patchy server" releases) [rst]
10432 Changes with Shambhala 0.4.4 30 Jun 1995
10434 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10435 *) Handle Addtype x/y .z [rst, reported by Cox]
10437 Changes with Shambhala 0.4.3
10439 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10440 synonymous [rst, terbush]
10442 Changes with Shambhala 0.4.1 28 Jun 1995
10444 *) First-cut virtual host implementation; some refit in the config
10445 reading code, and log management, was necessary to support this [rst]
10446 *) Sub-pool machinery, originally added to avoid excessive storage
10447 allocation on listings of large directories (which turned out to
10448 be the problem that the 0.3 storage accounting was added to
10449 find). Subrequests and mod_dir changed to use subpools. [rst]
10450 *) More memory debugging --- free list consistency checks. [rst]
10451 *) Added err_headers to request_rec, with support elsewhere [rst]
10452 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10454 Changes with Shambhala 0.3 19 Jun 1995
10456 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10457 *) Don't compile in mod_ai_backcompat by default
10458 *) Switch name of server from Apache to Shambhala in Makefile
10459 *) Add some accounting routines to track memory usage in the pools,
10462 Changes with Shambhala 0.2
10464 *) Set DOCUMENT_ROOT CGI variable
10465 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10466 *) Add critical section protection to handling of cleanup structures
10468 *) Significant code reorg within the server core to group related
10469 functions together [rst]
10470 *) Correctly handle clients that hang up before sending any request
10472 *) Replace dying child processes. [rst]
10474 Changes with Shambhala 0.1 12 Jun 1995
10476 Major rewrite of the pre-existing "patchy server" codebase, by
10477 Robert Thau (rst). Significant portions of the server code, such
10478 as configuration-file handling and HTTP authentication support,
10479 were ripped out and rewritten from scratch. Code that was not
10480 completely rewritten was significantly altered.
10482 Major changes with this release include:
10484 *) Introduction of the module API; in request handling, the central
10485 machinery just dispatches to various modules, which actually do
10486 most of the work. Configuration handling is similar --- modules
10487 declare their own commands, and the central machinery just
10488 dispatches to them.
10490 API features from shambhala/0.1 were substantially unchanged in
10491 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10492 release, such as wildcard handlers and subpools, were added in
10493 subsequent Shambhala releases, and were also generally rst's
10496 *) This release included the following modules:
10498 mod_access (access control --- allow and deny directives),
10499 mod_alias (Alias and Redirect commands),
10500 mod_auth (straight HTTP authentication, based on flat-files)
10501 mod_auth_dbm (same, with dbm files)
10502 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10503 mod_common_log (CLF access logs; later renamed mod_log_common)
10504 mod_dir (directory indexing)
10505 mod_include (server-side includes)
10506 mod_mime (AddType directives)
10507 mod_negotiation (content negotiation)
10508 mod_userdir (support for users' public_html directories)
10510 It also included a mod_ai_backcompat, which was a private hack
10511 for back-compatibility with rst's own AI-lab servers.
10513 All of these modules were substantially complete, and functional
10514 or nearly so (a few, which implemented features not in use at
10515 Thau's site, required patches of a few lines).
10517 *) sub-request machinery, to allow modules to determine how other
10518 modules would assign MIME types to a given file, or optionally
10519 serve its content (this is heavily used by mod_dir, mod_include
10520 and mod_negotiation).
10522 *) Resource pool system for keeping track of memory allocated and
10523 files opened in service of a particular request. Much of the
10524 code in the modules (when they weren't rewrites) was adjusted to
10525 replace a pervasive convention of using fixed-size buffers on
10526 the stack with an equally pervasive convention of using memory
10527 allocated with palloc().
10529 *) Reorganization of data structures associated with a given
10530 request to eliminate use of global variables and the troublesome
10531 unmunge_name function (used in NCSA and early Apache releases to
10532 attempt to determine the URI which mapped to a given filename
10533 --- a difficult proposition, given that it is easy to produce
10534 setups in which multiple URIs map to the same file).
10536 *) Source files renamed and rearranged
10538 *) Very simple pre-forking behavior --- parent process forked off a
10539 fixed number of children, and then just waited for SIGHUP.
10541 *) Other more minor changes too numerous to list.
10543 This release included modified versions of a lot of code from the
10544 Apache 0.6.4 public release, plus an early pre-forking patch
10545 codeveloped by Robert Thau and Rob Hartill.
10547 Changes with Apache 0.7.3 20 Jun 1995
10549 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10550 were incorporated by Rob Hartill on the main branch while Robert Thau
10551 worked on the Shambhala rewrite above. Most were merged into the
10552 Shambala architecture after Apache 0.8.0.
10554 Changes with Apache 0.6.4 13 May 1995
10556 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10559 Changes with Apache 0.5.1 10 Apr 1995
10561 Changes with Apache 0.4 02 Apr 1995
10563 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10566 Changes with Apache 0.3 24 Mar 1995
10568 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10571 Changes with Apache 0.2 18 Mar 1995
10573 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10574 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10575 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
