1 Changes with Apache 2.0.29-dev
3 *) Fix infinite loop in mod_cgid.c.
4 [Dale Ghent <daleg@elemental.org>, Brian Pane <bpane@pacbell.net>]
6 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
8 *) If shared modules are requested and mod_so is not available,
9 produce a fatal config-time error. [Justin Erenkrantz]
11 *) Improve http2env's performance by cutting the work it has to
12 do. [Brian Pane <bpane@pacbell.net>]
14 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
15 [Brian Pane <bpane@pacbell.net>]
17 Changes with Apache 2.0.28
19 *) When no port is given in a "ServerName host" directive, the
20 server_rec->port is now set to zero, not 80. That allows for
21 run-time deduction of the correct server port (depending on
22 SSL/plain, and depending also on the current setting of
23 UseCanonicalName). This change makes redirections
24 work, even with https:// connections. As in Apache-1.3, the
25 connection's actual port number is never used, only the ServerName
26 setting or the client's Host: setting. Documentation updated
27 to reflect the change. [Martin Kraemer]
29 *) Add a '%{note-name}e' argument to mod-headers, which works in
30 the same way as mod_log_confg. [Ian Holsman]
32 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
33 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
36 *) Introduce htdbm, a user management utility for db/dbm authorization
37 databases. [Mladen Turk <mturk@mappingsoft.com>]
39 *) Optimize usage of strlen and strcat in ap_directory_walk.
40 [Brian Pane <bpane@pacbell.net>]
42 Changes with Apache 2.0.27
44 *) Introduce an Apache mod_ssl initial configuration template
45 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
47 *) Fixed a memory leak in the getline parsing code that could
48 be triggered by arbitrarily large header lines. Requests
49 from the core input filter for single lines are now limited
50 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
52 *) Fix a truncation bug in how we print the port on the Via: header.
53 The routine that prints the Via: header now takes a length for
54 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
56 *) Some syntax errors in mod_mime_magic's magic file can result
57 in a 500 error, which previously was unlogged. Now we log the
60 *) Add the support/checkgid helper app, which checks the run-time
61 validity of group identifiers usable in the Group directive.
64 *) Various --enable-so options have been fixed: --enable-so is
65 treated as "static"; explicit --enable-so=shared issues an error;
66 and explicit --enable-so fails with error on systems without
67 APR_HAS_DSO. [Aaron Bannert]
69 *) Fix a segfault in the core input filter when the client socket
70 gets disconnected unexpectedly. [Cliff Woolley]
72 *) Fix the reporting for child processes that die. This removes
73 all of the non-portable W* macros from Apache.
74 [Jeff Trawick and Ryan Bloom]
76 *) Win32: Track and display "Parent Server Generation:" in
77 mod_status output. The generation will be bumped at
78 server graceful restart, when the child process exits
79 by hitting MaxRequestsPerChild or if the child
80 process exits abnormally. [Bill Stoddard]
82 *) Win32: Fix problem where MaxRequestsPerChild directive was
83 not being picked up in favor of the default. Enable
84 the parent to start up a new child process immediately upon
85 the old child starting shutdown.
88 *) Fix some bungling of the remote port in rfc1413.c so that
89 IdentityCheck retrieves the proper user id instead of failing
90 and thus always returning "nobody."
91 [Dick Streefland <Dick.Streefland@xs4all.nl>]
93 *) Introduced thread saftey for mod_rewrite's internal cache.
94 [Brian Pane <bpane@pacbell.net>]
96 *) Simplified mod_env's directives to behave as most directives are
97 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
98 directive following that UnsetEnv within the same container.
99 Also provides a runtime startup warning if a PassEnv configured
100 environment value is undefined. [William Rowe]
102 *) The worker MPM is now completely ported to APR's new lock API. It
103 uses native APR types for thread mutexes, cross-process mutexes,
104 and condition variables. [Aaron Bannert]
106 *) Sync up documentation to remove all references to the now deprecated
107 Port directive. [Justin Erenkrantz]
109 *) Moved all ldap modules from the core to httpd-ldap sub-project
112 *) Exit when we can't listen on any of the configured ports. This
113 is the same behavior as 1.3, and it avoids having the MPMs to
114 deal with bogus ap_listen_rec structures. [Jeff Trawick]
116 *) Cleanup the proxy code that creates a request to the origin
117 server. This change adds an optional hook, which allows modules
118 to gain control while the request is created if the proxy module
119 is loaded. The purpose of this hook is to allow modules to add
120 input and/or output filters to the request to the origin. While
121 I was at it, I made the core use this hook, so that proxy request
122 creation uses some of the code from the core. This can still be
123 greatly improved, but this is a good start. [Ryan Bloom]
125 Changes with Apache 2.0.26
127 *) Port the MaxClients changes from the worker MPM to the threaded
130 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
131 with the new input filtering system. [Justin Erenkrantz]
133 *) Introduce the MultiviewsMatch directive, to allow the operator
134 to be flexible in recognizing Handlers and Filters filename
135 extensions as part of the Multiviews matching logic, strict with
136 MultiviewsMatch NegotiatedOnly to accept only filename extentions
137 that designate negotiated parameters, (content type, charset, etc.)
138 or MultiviewsAll for the 1.3 behavior of matching any files, even
139 if they have unregistered extensions. [William Rowe]
141 *) Fixed the configure script to add a LoadModule directive to
142 the default httpd.conf for any module that was compiled
143 as a DSO. [Aaron Bannert <aaron@clove.org>]
145 *) rewrite mod_ssl input filtering to work with the new input filtering
146 system. [Justin Erenkrantz]
148 *) prefork: Don't segfault when we are able to listen on some but
149 not all of the configured ports. [Jeff Trawick]
151 *) Build mod_so even if no core modules are built shared.
152 [Aaron Bannert <aaron@clove.org>]
154 *) Introduce ap_directory_walk rewrite (with further optimizations
155 required) to adapt to the ap_process_request_internal() changes.
156 Optimized so subrequests and redirects now reuse previous section
157 merges, until we mismatch with the original directory_walk, and
158 precomputed r->finfo results will cause directory_walk to skip
159 the most expensive phases of the function. [William Rowe]
161 *) Allow ApacheMonitor to connect to and control Apache on other
162 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
164 *) Remove the Port directive. In it's place, the Listen directive
165 is now a required directive, which tells Apache what port to
166 listen on. The ServerName directive has also been extended
167 to accept an optional port. If the port is specified to the
168 ServerName, the server will report that port whenever it
169 reports the port that it is listening on. This change was
170 made to ease configuration errors that stem from having a Port
171 directive, and a Listen directive. In that situation, the server
172 would only listen to the port specified by the Listen command,
173 which caused a lot of confusion to users. [Ryan Bloom]
175 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
176 build, as loadable modules. [William Rowe]
178 *) Fix --enable-mods-shared processing. If most is specified,
179 then all modules that can be compiled as shared modules are.
180 [Aaron Bannert <aaron@clove.org>]
182 *) Update the mime.types file to map video/vnd.mpegurl to mxu
183 and add commonly used audio/x-mpegurl for m3u extensions.
184 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
186 *) Eliminate the depreciated r->content_language, in favor of the array
187 r->content_languages introduced many years ago. Module authors must
188 substantially overhaul their modules, so this needs to be upgraded
189 if the module still relied on backwards-brokeness. [William Rowe]
191 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
194 *) Rewrite the input filtering mechanisms to consolidate and reorganize
195 code. In short, core_input_filter does something now and
196 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
198 *) Update the Win32 build to re-absorb mod_proxy and family.
201 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
202 current SDK.) [William Rowe]
204 *) Some style changes to the code that does ProxyErrorOverride. Fixed
205 config merge behaviour. [Graham Leggett]
207 *) Allow support programs to be compiled against a static version
208 of libapr. This allows the smaller support programs to be
209 relocated. [Aaron Bannert <aaron@clove.org>]
211 *) Update the mime.types file to the registered media types as
212 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
214 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
215 number of clients that can connect at the same time, instead of
216 specifying the maximum number of child processes.
217 [Aaron Bannert <aaron@clove.org>]
219 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
220 be consistent with 1.3. [Justin Erenkrantz]
222 *) Cache apr_explode_localtime() value for 15 seconds.
223 [Brian Pane <bpane@pacbell.net>]
225 *) Fix mod_include to not return ETag or Last-Modified headers.
226 [Ian Holsman <ianh@cnet.com>]
228 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
230 *) Eliminate the wasteful run-time conversion of method names from strings
231 to numbers in places where the methods are known at compile time.
232 [Brian Pane <bpane@pacbell.net>]
234 *) Turn the worker MPM's queue into a LIFO. This may
235 improve cache-hit performance under some conditions.
236 [Aaron Bannert <aaron@clove.org>]
238 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
239 support it. [Justin Erenkrantz]
241 *) Cleanup the worker MPM. We no longer re-use transaction
242 pools. This incurs less overhead than shuffling the pools
243 around so that they can be re-used. Remove one of the
244 queue's condition variables. We just redefined the API to
245 state that you can't try to add more stuff than you allocated
246 segments for. [Aaron Bannert <aaron@clove.org>]
248 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
250 *) Fixed persistent connections when a request contains a body.
253 *) mod_dav uses a new API to speak to the backend provider for dead
254 property management. [Greg Stein]
256 *) Remove the Win32 script-processing exception from mod_cgi, and
257 roll build_command_line/build_argv_list into a unified, overrideable
258 ap_cgi_build_command optional function. [William Rowe]
260 *) Rewrite find_start_sequence to use a better search algorithm
261 to find the start tag. [Justin Erenkrantz]
263 *) Fix a seg fault in mod_include. When we are generating an
264 internal redirect, we must set r->uri to "", not a bogus
265 string, and not NULL. [Ryan Bloom]
267 *) Optimized location_walk, so subrequests, redirects and second passes
268 now reuse previous section merges on a <Location > by <Location >
269 basis, until we mismatch with the original location_walk.
272 *) Back out the 1.45 change to util_script.c. This change made
273 us set the environment variable REQUEST_URI to the redirected
274 URI, instead of the originally requested URI.
275 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
277 *) Make mod_include do lazy evaluation of potentially expensive to
278 compute variables. [Brian Pane <bpane@pacbell.net>]
280 *) Fix logging of bytes sent for HEAD requests. %b and %B should
281 log either - or 0, before this patch, they were both logging
282 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
284 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
285 than per character. [Brian Pane <bpane@pacbell.net>]
287 *) Normalize the primary request, redirects and sub-requests to
288 run the same ap_process_request_internal for consistency in
289 robustness, behavior and security. [William Rowe]
291 *) Fix a segfault with mod_include when r->path_info is not set
292 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
294 *) Add -X functionality back. This indicates to all MPMs and any other
295 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
297 *) Some initial support for the cygwin platform [prefork only].
298 This is not to be confused with support for the WinNT/Win32
299 platform, which is the recommended configuration for native
300 Win32 users. The cygwin platform support is recommended for
301 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
303 *) Changed syntax of Set{Input|Output}Filter. The list of filters
304 must be semicolon delimited (if more than one filter is given.)
305 The Set{Input|Output}Filter directive now overrides a parent
306 container's directive (e.g. SetInputFilter in <Directory /web/foo>
307 will override any SetInputFilter directive in <Directory /web>.)
308 This new syntax is more consistent with Add{Input|Output}Filter
309 directives defined in mod_mime. Also cures a bug in prior releases
310 where the Set{Input|Output}Filter directive would corrupt the
311 global configuration if the multiple directives were nested.
314 *) Cured what's ailed mime for quite some time. If an AddSomething
315 was given in the configuration (Language, Charset, Handler or
316 Encoding) Apache would set the content type as given by AddType,
317 but refused to check the mime.types file if AddType wasn't given
318 for that specific extension. Setting the AddHandler for .html
319 without setting the AddType text/html html would cause Apache to
320 use the default content type. [William Rowe]
322 *) Added some bulletproofing to memory allocation in the LDAP cache
323 code. [Graham Leggett]
325 Changes with Apache 2.0.25
327 *) Move the installed /manual directory out of the /htdocs/ tree, so
328 that it can be kept more independently from the remaining document
329 root. The "Alias /manual ..." already allowed for easy projection
330 into existing private document trees. [Martin Kraemer]
332 *) Add specified user attributes to the environment when using
333 mod_auth_ldap. This allows you to use mod_include to embed specified
334 user attributes in a page like so:
335 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
338 *) Fix a performance problem with the worker MPM. We now create
339 transaction pools once, and re-use them for each connection.
340 [Aaron Bannert <aaron@clove.org>]
342 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
343 of a 'handler' or 'filter', so that any filename extension that does
344 not contribute to the negotiated metadata can't be served without
345 an explicit request. E.g., if the .Z extension is associated with
346 an unzip filter, the user request somefile.Z.html, mod_negotiation
347 won't serve it. It can serve somefile.Z.html when somefile.Z is
348 requested, since the .Z extension is explictly requested, if the
349 .html extension is associated with ContentType text/html.
352 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
353 and corresponding AddOutputFilter syntax, to insert one or more
354 filters by mod_mime filename extension processing.
357 *) Fix a growing connection pool in core_output_filter() for
358 keepalive requests. [Jeff Trawick]
360 *) Moved split_and_pass_pretag_buckets back to being a
361 macro at Ryans's request. Removed the return from it
362 by setting and returning a return code instead. Updated
363 the code to check the return code from the macro and
364 do the right thing. [Paul J. Reder]
366 *) Fix a segfault when a numeric value was received for Host:.
369 *) Add a function ap_remove_input_filter. This is to match
370 up with ap_remove_output_filter. [Ryan Bloom]
372 *) Clean up location_walk, so that this step performs a minimum
373 amount of redundant effort (it must be run twice, but it will no
374 longer reparse all <Location > blocks when the request uri
375 hadn't changed.) [William Rowe]
377 *) Eliminate proxy: (and all other 'special') processing from the
378 ap_directory_walk() phase. Modules that want to use special
379 walk logic should refer to the mod_proxy map_to_location example,
380 with it's proxy_walk and proxysection implementation. This makes
381 either directory_walk flavor much more legible, since that phase
382 only runs against real <Directory > blocks.
385 *) Fix a security problem in mod_include which would allow
386 an SSI document to be passed to the client unparsed.
387 [Cliff Woolley, Brian Pane]
389 *) Introduce the map_to_storage hook, which allows modules to bypass
390 the directory_walk and file_walk for non-file requests. TRACE
391 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
392 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
395 *) Add the ability for mod_include to add the INCLUDES filter
396 if the file is configured for the server-parsed handler.
397 This makes the configuration for .shtml files much easier
398 to understand, and allows mod_include to honor Apache 1.3
399 config files. Based on Doug MacEachern's patch to PHP
400 to do the same thing. [Ryan Bloom]
402 *) force OpenSSL to ignore process local-caching and to always
403 get/set/delete sessions using mod_ssl's callbacks
404 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
405 Geoff Thorpe <geoff@geoffthorpe.net>]
407 *) Make the worker MPM shutdown and restart cleanly. This also
408 cleans up some race conditions, and gets the worker using
409 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
411 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
413 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
415 *) Fix for mod_include. Ryan's patch to check error
416 codes put a return in the wrong place. Also, the
417 include handler return code wasn't being checked.
418 I don't like macros with returns, so I converted
419 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
420 [Paul J. Reder <rederpj@raleigh.ibm.com>]
422 *) fix segv in mod_mime if no AddTypes are configured
423 [John Sterling <sterling@covalent.net>]
425 *) Enable ssl client authentication at SSL_accept time
426 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
428 *) Fix a segfault in mod_include when the original request has no
429 associated filename (e.g., we're filtering the error document for
430 a bad URI). [Jeff Trawick]
432 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
434 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
435 of httpd is started and shuts down due to socket conflict. Moving the
436 call to ap_log_pid solves the problem.
438 *) Changed the late-1.3 log_config substitution %c to %X, to log the
439 status of the closed connection, as it conflicts with the far more
440 common, historical ssl logging directive %...{var}c. [William Rowe]
442 *) Added the common error/ tree to the build/install targets
443 (similar to the common icons/ tree) for the multi-language error
444 messages that Lars committed earlier. [William Rowe]
446 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
448 *) Added a default commented-out mod_ldap and mod_auth_ldap
449 configuration to httpd-std.conf and httpd-win.conf
452 *) Added documentation for mod_ldap and mod_auth_ldap.
455 *) Enabled negative caching on attribute comparisons in the LDAP cache.
456 Fixed a problem where the default cache TTL was set in milliseconds
457 not microseconds causing the cache to time out almost immediately.
460 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
461 module code to follow APR. [Graham Leggett]
463 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
464 cleaned up when the connection pool pool is cleaned up.
467 *) Fix a minor issue with Jeff Trawick's mod_include
468 patch. Without this patch, the code will just allocate
469 more bytes in get_combined_directive than are needed.
472 *) Added the LDAP authentication module mod_auth_ldap.
473 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
475 *) Added the LDAP cache and connection pooling module mod_ldap.
476 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
478 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
479 by allowing a module to disable itself if its prerequisites are not
480 met. [Justin Erenkrantz]
482 Changes with Apache 2.0.24
484 *) Fix a couple of issues in mod_include when the tag appeared at
485 offsets near 8192 in the file being parsed. [Jeff Trawick]
487 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
488 reached. [Jeff Trawick]
490 *) Numerous improvements to the Win32 build system. Introduced command line
491 builds without requiring .mak files for MSVC 6.0 and later versions.
492 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
495 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
496 reporting of uninstalled services and other error conditions, and changed the
497 default service name to Apache2. [William Rowe]
499 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
500 compatibility with existing Apache 1.3 Win32 Apache management utilites.
501 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
503 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
504 [William Rowe, Greg Ames]
506 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
507 and RemoveCharset directives. [William Rowe]
509 *) The Unix MPMs other than perchild now allow child server
510 processes to use the accept mutex when starting as root and
511 using SysV sems for the accept mutex. Previously, this
512 combination would lead to fatal errors in the child server
513 processes. perchild can't use SysV sems because of security
514 issues. [Jeff Trawick, Greg Ames]
516 *) Added Win32 revision stamp resources to all http binaries
517 (including modules/ and support/ tools.) PR7322 [William Rowe]
519 *) Fix ap_rvprintf to support more than 4K of data at one time.
520 [Cody Sherr <csherr@covalent.net>]
522 *) We have always used the obsolete/deprecated Netscape syntax
523 for our tracking cookies; now the CookieStyle directive
524 allows the Webmaster to choose the Netscape, RFC2109, or
525 RFC2965 format. The new CookieDomain directive allows the
526 setting of the cookie's Domain= attribute, too. PR #s 5006,
527 5023, 5920, 6140 [Ken Coar]
529 *) Tweak server/Makefile so that the rules for generating exports.c
530 are compatible with make utilities which don't expand wildcards
531 in a dependency list (e.g., OS/390 make, certain levels of GNU
532 make). [Jeff Trawick]
534 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
536 *) Begin to sanitize the MPM configuration directives. Now, all
537 MPMs use the same functions for all common MPM directives. This
538 should make it easier to catch all bugs in these directives once.
539 [Cody Sherr <csherr@covalent.net>]
541 *) Close a major resource leak. Every time we had issued a
542 graceful restart, we leaked a socket descriptor.
545 *) Fix a problem with the new method code. We need to cast
546 the 1 to an apr_int64_t or it will be treated as a 32-bit
547 integer, and it will wrap after being shifted 32 times.
548 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
550 *) Fix a bug in mod_expires. Previous to this patch, if you
551 told mod_expires to add 604800 seconds to the last-modified
552 time, it actually added 604800 usec's to the last-modified time,
553 so that when looking at the response it looked like nothing
554 had been done. The root of the problem was that we always compute
555 time in usec's, but we ask users to input sec's. This means we
556 need to convert to usec's before using those values.
559 *) The worker MPM now handles shutdown and restart requests. It
560 definitely isn't perfect, but we do stop the servers correctly.
561 The biggest problem right now is that SIGHUP causes the server to
562 just die. [Ryan Bloom]
564 Changes with Apache 2.0.23
566 *) Use the prefork MPM by default on Unix. [various]
568 *) Added a systray icon monitor application for Win32.
569 [Mladen Turk <mturk@mappingsoft.com>]
571 *) mod_rewrite: Fix the line ending on some non-Unix systems for
572 messages written to the rewrite log.
573 [Richard Labennett <rlabenn@us.ibm.com>]
575 *) All mod_autoindex query parsing is now quietly quashed with the
576 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
577 still drops the column sort <a href>'s for the column headers, but
578 IgnoreClient is required to ignore these Query options entirely.
581 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
582 to allow the client to select plain, FancyIndexing or HTMLTable
583 formatting, V=[0|1] to inhibit or enable version sorting, and
584 P=pattern to return only specific files. The old Query Arguments
585 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
586 as before), and O=A|D for ordering ascending or descending.
589 *) Fixed an error in mod_include's directive parsing routines which
590 caused #if, #elif, and #else expressions containing backslashes
591 to be improperly evaluated. [Cliff Woolley]
593 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
594 drop the icon column, SuppressRules to drop the <hr> elements,
595 and HTMLTable to create rudimentary HTML table listings (implies
596 FancyIndexing). [William Rowe]
598 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
599 from Apache 1.3.15. This is needed for two reasons, first, given
600 multiple machines within a server farm, ETags and Last-Modified
601 stamps won't correspond from machine to machine, and second, many
602 Unixes don't capture changes to the date or time stamp of existing
603 files, since these don't modify the dirent itself. [William Rowe]
605 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
606 and DirectoryWidth options from Apache 1.3.10.
607 [William Rowe, Ken Coar]
609 *) Eliminated FancyIndexing directive, deprecated early in Apache
610 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
612 *) mod_autoindex now excludes any file names that would result in
613 an error, other than a success or redirect. Also optimized
614 the parent directory, always included except in the URI '/'.
617 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
618 negotiated index pages, and prevent the server from defaulting
619 to an autoindex of the directory. mod_negotiation will now die
620 with a 500 Internal Error if it could match some filenames
621 (e.g. for mod_dir) but none can be served. mod_negotation now
622 refuses to serve any file with an extention that mod_mime doesn't
623 recognize, and wasn't part of the request. [William Rowe]
625 *) Eliminate mod_cgi's handling of .exe files without the .exe file
626 extension. This is already handled by multiviews, if the admin
627 wishes to AddHandler .exe or define a content type handler and
628 associate .exe files with that content type. Multiviews must be
629 enabled to allow these to be served. [William Rowe]
631 *) Speed up the server's response to a spike in incoming workload
632 or restarts by assigning empty scoreboard slots to new processes
633 when they are available. [Greg Ames]
635 *) Add a handler to mod_includes.c. This handler is designed to
636 implement the XbitHack directive. This can't be done with a
637 fixup, because we need to check the content-type, which is
638 only available in the handler phase. [Ryan Bloom]
640 *) Make the includes filter check return codes from filters lower in
641 the filter chain. If a lower level filter returns an error, then
642 the request needs to stop immediately. This allows mod_include to
643 stop parsing data once a lower filter recognizes an error.
646 *) Add the ability to extend the methods that Apache understands
647 and have those methods <limit>able in the httpd.conf. It uses
648 the same bit mask/shifted offset as the original HTTP methods
649 such as M_GET or M_POST, but expands the total bits from an int to
650 an ap_int64_t to handle more bits for new request methods than
651 an int provides. [Cody Sherr <csherr@covalent.net>]
653 *) Fix broken mod_mime behavior in merging its arguments. Possible
654 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
656 *) Solve many mod_ssl porting issues (too many to detail) with
657 help from the whole team, but most notably [Ralf S. Engelschall,
658 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
659 Doug MacEachern, William Rowe, Cliff Woolley]
661 *) More stall fixes for the threaded & worker mpm's.
662 Make mod_status output more accurate. Don't
663 count workers in processes which aren't actively
664 serving requests. [Greg Ames]
666 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
668 *) Add a single listener/multiple worker MPM. This MPM is
669 definately not fully correct, but it allows us to solve many
670 of the problems that exist in the threaded MPM. This is a
671 modified version of the threaded MPM. [Ryan Bloom]
673 *) Improve content generation throughout Apache, providing closer
674 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
675 Transitional specifications. [William Rowe]
677 Changes with Apache 2.0.22
679 *) Fix a problem where the threaded MPM stalls after restarts or
680 segfaults. Also prevent multiple active processes from using
681 the same scoreboard slot. [Greg Ames]
683 *) Apache/Win32 now fills in the service description with Apache's
684 server version string, including loaded and advertised modules.
687 *) Improved support for the Win32 build, to recover gracefully from
688 missing apr or apr-util directories or the awk interpreter,
689 create the proper cgi-bin examples, including a test-cgi.bat, and
690 fix the perl shebang line for printenv.pl, when installing from
691 the build environment. [William Rowe]
693 *) Fix a segfault in threaded.c caused by passing uninitialized
694 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
696 *) Use new APR number conversion functions to reduce CPU consumption
697 when setting the content length, and in mod_log_config.
700 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
701 where HEAD response headers were being repeated twice for
702 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
703 problem in the http_header filter was exposed by the recent rewrite
704 of the content_length filter. [Taketo Kabe, Bill Stoddard]
706 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
707 restarts. A garbage pointer to a vhost's server_rec from the
708 previous generation was being left around under certain
709 conditions. [Greg Ames]
711 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
712 used to appear as '(none', without the closing paren.
713 [Günter Knauf <eflash@gmx.net>]
715 *) Improve the exports generating awk script. In the past, we had
716 work around problems in the awk script by avoiding some #if and
717 #ifdefs. This has bitten us many times in generating the exports.c
718 file. This improvement allows corrects the header file parsing.
719 [Sander Striker <striker@apache.org>]
721 Changes with Apache 2.0.21
723 *) Resolve the Win32 htpasswd bug, where a file that existed would be
724 overwritten, regardless of the -c flag.
725 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
727 *) Introduce connection sub-pools into ab. Truncating the lifetime
728 of these allocations means that ab no longer perpetually grows
729 its working set, running out of memory on large request attempts.
732 *) Make scoreboard creation a hook. This allows management
733 modules to have access to the scoreboard at the time that it is
734 created, and at every restart request.
735 [Cody Sherr <csherr@covalent.net>]
737 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
738 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
739 daemon index actually used in the scoreboard. I also
740 updated the pertinent calls. [Paul J. Reder]
742 *) Win32: Prevent listening sockets from being inherited by
743 the Apache child process, CGI scripts, rotatelog process
744 etc. If the Apache child process segfaults, any processes
745 that the child started are not reaped. Prior to this fix,
746 these processes inherited the listening sockets which sometimes
747 prevented the restarted Apache child process from accepting
748 connections (ie, the server would hang).
751 *) Provide vhost and request strings when ExtendedStatus is on.
754 *) Fix some issues with the pod and prefork: check the pod *after*
755 processing a connection so that a server processing a time-
756 consuming request bails out as soon as practical; when the
757 parent process wakes up a server process via connect(), use an
758 APR timeout on the connect() so that we don't hang for a long
759 time if there aren't server processes around to do accept().
760 [Jeff Trawick, Greg Ames]
762 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
763 spends a lot of time in apr_table_get calls. Using the default
764 httpd.conf, the tables for languages and charsets are somewhat
765 large, so the time spent scanning them on each request is
766 significant. Replacing the tables with hash tables provides
767 a nice speedup. [Brian Pane <bpane@pacbell.net>]
769 *) Add two functions to allow modules to access random parts of the
770 scoreboard. This allows modules compiled for one MPM to access the
771 scoreboard, even if it the server was compiled for another MPM.
772 [Harrie Hazewinkel <harrie@covalent.net>]
774 Changes with Apache 2.0.20
776 *) Fix problem in content-length filter where the filter would
777 buffer all the output from a CGI before sending any bytes
778 down the filter stack to the network. This problem would cause
779 significant memory consumption if the CGIs generated
780 lots of bytes. [Bill Stoddard]
782 *) Get non-blocking CGI pipe reads working with the bucket brigades.
785 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
788 *) Fix a bug in the threaded MPM that would cause it to kill off all
789 workers immediately after starting if the number of workers started
790 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
792 Changes with Apache 2.0.19
794 *) Fix problem with threaded MPM. The problem was that if each child
795 process was busy serving a single long-lived request and the server
796 was sent a graceful restart signal, the server would stop serving
797 requests. This would happen because each child process would wait to
798 die until the last thread was done, and the parent wouldn't spawn any
799 new children until a process died. Now, the parent looks at the fact
800 that the children are dying gracefully, and starts new children.
801 Those new children only start enough threads to compliment the number
802 of threads in the other child process that shares the same spot in
803 the scoreboard. In this way, we make sure to never go over
804 MaxClients. [Ryan Bloom]
806 *) modified mod_negotiation and mod_autoindex to speed up by almost a
807 factor of two on apr_dir_read()-enhanced platforms, such as Win32
808 and OS2, by calling ap_sub_request_lookup_dirent() with the results
809 already provided by apr_dir_read(). [William Rowe]
811 *) mod_file_cache is now more robust to filtering and serves requests
812 slightly more efficiently. [Cliff Woolley]
814 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
815 Module was calling ap_rwrite() followed by ap_rflush() but the
816 served content was not being displayed in the browser. Inspection
817 of the output stream revealed that the first data chunk was
818 missing the trailing CRLF required by the RFC. [Bill Stoddard]
820 *) apxs no longer generates ap_send_http_header() in the example handler
822 *) Fix an ab problem which could cause a divide-by-zero exception
823 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
824 [Ian Holsman <ianh@cnet.com>]
826 *) Solve case-insensitive platforms' confusion about negotiated
827 filenames, allowing files of differnt case to match in choosing
828 the document to serve. [William Rowe]
830 *) Fix brokenness when ThreadsPerChild is higher than the built-in
831 limit. We left ap_threads_per_child at the higher value which
832 led to segfaults when doing certain scoreboard operations.
835 *) Fix seg faults and/or missing output from mod_include. The
836 default_handler was using the subrequest pool for files and
837 MMAPs, even though the associated APR structures typically
838 live longer than the subrequest. [Greg Ames]
840 *) Extend mod_setenvif to support specifying regular expressions
841 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
842 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
843 will cause HAVE_TS to be set if any of the request headers begins
844 with "TS" and has a value that begins with any character in the
845 set [a-z]. [Bill Stoddard]
847 *) httpd children now re-bind themselves to a random CPU on
848 multiprocessor systems on AIX via bindprocessor() in 2.0.
849 [Victor J. Orlikowski]
851 *) Fix htdigest. It would go into a loop in getline when adding
852 a second user. [Bill Stoddard]
854 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
856 *) Automatically generate httpd.exp for AIX.
857 DSOs now work again on AIX in 2.0
858 [Victor J. Orlikowski]
860 *) Add a new request hook, error_log. This phase allows modules
861 to act on the error log string _after_ it has been written
862 to the error log. The goal for this hook is to allow monitoring
863 modules to send the error string to the monitoring agent.
866 *) Modify mod_echo to make it use filters for input and output.
867 [Ryan Morgan <rmorgan@covalent.net>]
869 *) Extend mod_headers to support conditional driven Header
870 add, append and set. Use SetEnvIf to set an envar and conditionally
871 add/append/set headers based on this envar thusly:
873 SetEnvIf TSMyHeader value HAVE_TSMyHeader
874 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
876 If the request contains header "TSMyHeader: value" then header
877 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
880 *) Extend mod_headers to support using format specifiers on Header
881 add, append and set header values. Two format specifiers are supported:
883 %t - reports, in UTC microseconds since the epoch, when the
884 request was received.
886 %D - reports the time, in microseconds, between when the request was
887 received and the response sent.
890 Header add MyHeader "This request served in %D microseconds. %t"
892 results in a header being added to the response that looks like this:
894 MyHeader: This request served in D=5438 microseconds. t=991424704447256
898 *) Fix reset_filter(). We need to be careful how we remove filters.
899 If we set r->output_filters to NULL, we also have to reset the
900 connection's filters. [John Sterling]
902 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
904 *) Add a check to ap_die() to make sure the filter stack is sane and
905 contains the correct basic filters when an error occurs. This fixes
906 a problem where headers are not being sent on error. [John Sterling]
908 *) New Header directive 'echo' option. "Header echo regex" will
909 cause any headers received on the request that match regex to be
910 echoed to (included in) the response headers.
913 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
914 This prevented the inclusion of apr_compat.h. PR #7773
915 [Oleg Broytmann <phd@phd.pp.ru>]
917 *) Moved util_uri to the apr-util library. This required a bunch of
918 apr_name changes for the uri utility functions. [Justin Erenkrantz]
920 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
921 insert_filter phase so that other filters are not bypassed by default.
924 *) Reimplement mod_headers as an output filter. mod_headers can now
925 add custom headers to inbound requests using the RequestHeader directive
926 and to responses using the same old Header directive. [Graham Leggett]
928 Changes with Apache 2.0.18
930 *) Fix command-line processing so that if a bad argument is specified
931 Apache will exit. [Jeff Trawick]
933 *) Change the make targets and rules to be consistent in all of the
934 Apache-owned source trees. [Roy Fielding]
936 *) Fix processing of the TRACE method. Previously we passed bogus
937 parms to form_header_field() and it overlaid some vhost structures,
938 resulting in a segfault in check_hostalias().
939 [Greg Ames, Jeff Trawick]
941 *) Win32: Add support for reliable piped logs. If the logging process
942 goes down, Apache will automatically restart it. This function has
943 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
946 *) Do not start piped log processes during the config file
947 preflight. This change also circumvents a problem on
948 Windows where the rotatelog processes created during preflight
949 was not getting cleaned up properly.
952 *) add "Request Phase Participation" info to mod_info
955 *) Make first phase changes to the scoreboard data structures in
956 preparation for the rewriting of the scoreboard per my posted
957 design notes. [Paul J. Reder]
959 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
960 and apr-util, allow it to be overridden by the configure command-line
961 (default="--silent") and introduce LT_LDFLAGS to replace what we were
962 formerly abusing as LTFLAGS. [Roy Fielding]
964 *) Clean up the reporting of incorrect closing container tags.
965 [Barrie Slaymaker <barries@slaysys.com>]
967 *) Simplify the configure process by moving all libtool stuff to APR
968 and moving hints.m4 inline. [Roy Fielding]
970 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
971 of functions used by mod_proxy for export in the DLL
972 [Ian Holsman <IanH@cnet.com>]
974 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
975 request body from its stdin but no reqest body is being written to
976 the cgi. [Jeff Trawick]
978 *) mod_log_config: %c connection status incorrectly logged
979 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
982 *) Get mod_cern_meta working under Windows
985 *) Create Files, and thus MMAPs, out of the request pool, not the
986 connection pool. This solves a small resource leak that had us
987 not closing files until a connection was closed. In order to do
988 this, at the end of the core_output_filter, we loop through the
989 brigade and convert any data we have into a single HEAP bucket
990 that we know will survive clearing the request_rec.
991 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
994 *) Completely revamp configure so that it preserves the standard make
995 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
996 the configure additions to EXTRA_* variables. Also, allow the user
997 to specify NOTEST_* values for all of the above, which eliminates the
998 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
999 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
1000 avoid pointless duplications. Fix the order in which flags are given
1001 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
1002 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1003 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1004 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1006 *) Get mod_tls to compile/work better on Windows. PR #7612
1007 [Bernhard Schrenk <b.schrenk@improx.com>]
1009 *) Fix shutdown/restart hangs in the threaded MPM.
1010 [Jeff Trawick, Greg Ames, Ryan Bloom]
1012 *) Removed the keptalive boolean from conn_rec because it is now only
1013 used by a single routine and can be replaced by a local variable.
1014 [Greg Stein, Ryan Bloom, Roy Fielding]
1016 *) Patch prefork to put enough of the signal processing back in so that
1017 signals are all handled properly now. The previous patch fixed the
1018 deadlock race condition, but broke the user directed signal handling.
1019 This fixes it to work the way it did before my previous prefork patch
1020 (primarily, SIGTERM is now working).
1022 *) Change how input filters decide how much data is returned to the
1023 higher filter. We used to use a field in the conn_rec, with this
1024 change, we use an argument to ap_get_brigade to determine how much
1025 data is retrieved. [Ryan Bloom]
1027 *) Fix seg fault at start-up introduced by Ryan's change to enable
1028 modules to specify their own logging tags. mod_log_config
1029 registers an optional function, ap_register_log_handler().
1030 ap_register_log_handler() was being called by http_core before
1031 the directive hash table was created. This patch creates the
1032 directive hash table before ap_register_log_handler() is
1033 registered as an optional function.
1034 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1036 *) Add ap_set_int_slot() function
1037 [John K. Sterling <sterling@covalent.net>]
1039 *) Under certain circumstances, Apache did not supply the
1040 right response headers when requiring authentication.
1041 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1042 (This is a port of the change that went into Apache 1.3.19.)
1044 *) Allow modules to specify their own logging tags. This basically
1045 allows a module to tell mod_log_config that when %x is encountered
1046 a specific function should be called. Currently, x can be any single
1047 character. It may be more useful to make this a string at some point.
1050 Changes with Apache 2.0.17
1052 *) If a higher-level filter handles the the byterange aspects of a
1053 request, then the byterange filter should not try to redo the
1054 work. The most common case of this happening, is a byterange
1055 request going through the proxy, and the origin server handles
1056 the byterange request. The proxy should ignore it.
1057 [Graham Leggett <minfrin@sharp.fm>]
1059 *) Changed the threaded mpm to have child_main join to each of the
1060 worker threads to make sure the kids are all gone before child_main
1061 exits after a signal (cleanup from perform_idle_server_maintenance).
1062 This is an extension of Ryans recent commit to make the child_main
1065 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1066 report if their threads are dynamic or static. Finally, this also
1067 implements a new API, ap_show_mpm, which returns the MPM that was
1068 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1070 *) Do not install the binaries from the support directory twice.
1071 [jun-ichiro hagino <itojun@iijlab.net>]
1073 *) The ap_f* functions should flush data to the filter that is passed
1074 in, not the the filter after the one passed in.
1075 [Ryan Morgan <rmorgan@covalent.net>]
1077 *) Make ab work again by changing its native types to apr types and formats.
1078 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1080 *) Move the byterange filter and all of the supporting functions back
1081 to the HTTP module. The byterange filter turned out to be very
1082 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1084 *) Make clean, distclean, and extraclean consistently according to the
1085 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1087 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1088 This may have been causing problems stopping processes in the threaded
1091 *) Fix content-length in mod_negotiation to a long int representation.
1094 *) Remove BindAddress from the default config file.
1095 [giles@nemeton.com.au]
1097 *) Allow module authors to add a module to their Apache build using
1098 --with-module, without re-running buildconf. The syntax is:
1099 --with-module=module_type:/path/to/module.c
1100 The configure script will copy the module.c file to
1101 modules/module_type, and it will be added to the relevant Makefiles.
1102 currently, this only works for static modules. [Ryan Bloom]
1104 *) Changes required to make prefork clean up idle children properly.
1105 There was a window during which a starting worker deadlocks when
1106 an idle cleanup arrives before it completes init. Apache then keeps
1107 trying to cleanup the same deadlocked worker forever (until higher
1108 pids come along, but it still will never reduce below the deadlocked
1109 pid). Thus the number of children would not reduce to the correct
1110 idle level. [Paul J. Reder]
1112 Changes with Apache 2.0.16
1114 *) Change the default installation directory to /usr/local/apache2,
1115 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1117 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1120 *) Get MaxRequestsPerChild working with the Windows MPM.
1123 *) Make generic hooks to work, with mod_generic_hook_import/export
1124 experimental modules. [Ben Laurie, Will Rowe]
1126 *) Fix segfaults for configuration file syntax errors such as
1127 "<Directory>" followed by "</Directory" and
1128 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1130 *) Cleanup the --enable-layout option of configure. This makes
1131 us use a consistent location for the config.layout file, and it
1132 makes configure more portable.
1133 [jun-ichiro hagino <itojun@iijlab.net>]
1135 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1136 csv/gnuplot format, rudimentary ssl support and various other tweaks
1137 to make results more true to what is measured. The upshot of this it
1138 turns out that 'ab' has often underreported the true performance of
1139 apache. Often by a order of magnitude :-) See talk/paper of Sander
1140 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1141 [Dirk-Willem van Gulik]
1143 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1144 storage leak this ensures that some unnecessary pipes are closed.
1147 *) Performance: Add quick_handler hook. This hook is called at the
1148 very beginning of the request processing before location_walk,
1149 translate_name, etc. This hook is useful for URI keyed content
1150 caches like Mike Abbott's Quick Shortcut Cache.
1153 *) top_module global variable renamed to ap_top_module [Perl]
1155 *) Move ap_set_last_modified to the core. This is a potentially
1156 controversial change, because this is kind of HTTP specific. However
1157 many protocols should be able to take advantage of this kind of
1158 information. I expect that headers will need one more layer of
1159 indirection for multi-protocol work, but this is a small step in
1160 the right direction. [Ryan Bloom]
1162 *) Enable mod_status by default. This matches what Apache 1.3 does.
1165 *) Add a ScriptSock directive to the default config file. This is
1166 only enabled when mod_cgid is used.
1167 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1169 Changes with Apache 2.0.15
1171 *) Untangled the buildconf script and eliminated the need for build's
1172 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1173 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1175 *) Win32: Don't accept more connections than we have worker threads
1179 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1180 to fork() new child processes.
1183 *) Fix a major security problem with double-reverse lookup checking.
1184 Previously, a client connecting over IPv4 would not be matched
1185 properly when the server had an IPv6 listening socket. PR #7407
1186 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1188 *) Change the way the beos MPM handles polling to allow it to stop and
1189 restart. Problem was the sockets being polled were being reset by
1190 the select call, so once it had accepted a connection it was no
1191 longer listening on the UDP socket we use for shutdown instructions.
1192 APR needs to be altered, patch on it's way. [David Reid]
1194 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1195 on error exit from ap_getline(). Some other code got upset because
1196 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1198 *) Handle ap_discard_request_body() being called more than once.
1199 [Greg Ames, Jeff Trawick]
1201 *) Get rid of an inadvertent close of file descriptor 2 in
1202 mod_mime_magic. [Greg Ames, Jeff Trawick]
1204 *) Add a hook, create_request. This hook allows modules to modify
1205 a request while it is being created. This hook is called for all
1206 request_rec's, main request, sub request, and internal redirect.
1207 When this hook is called, the the r->main, r->prev, r->next
1208 pointers have been set, so modules can determine what kind of
1209 request this is. [Ryan Bloom]
1211 *) Cleanup the build process a bit more. The Apache configure
1212 script no longer creates its own helper scripts, it just
1214 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1216 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1217 proxy requests. [Graham Leggett]
1219 *) Avoid using sscanf to determine the HTTP protocol number in
1220 the common case because sscanf is a performance hog. From
1221 Mike Abbot's Accelerating Apache patch number 6.
1222 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1224 *) Fix a security exposure in mod_access. Previously when IPv6
1225 listening sockets were used, allow/deny-from-IPv4-address rules
1226 were not evaluated properly (PR #7407). Also, add the ability to
1227 specify IPv6 address strings with optional prefix length on Allow
1228 and Deny. [Jeff Trawick]
1230 *) Enhance rotatelogs so that a UTC offset can be specified, and
1231 the logfile name can be formatted using strftime(3). (Brought
1232 forward from 1.3.) [Ken Coar]
1234 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1235 DuplicateHandle on an IOCompletionPort (a practice which
1236 MS "discourages"). The new model does not rely on associating
1237 the completion port with the listening sockets, thus the
1238 completion port can be completely managed within the child
1239 process. A dedicated thread accepts connections off the network,
1240 then calls PostQueuedCompletionStatus() to wake up worker
1241 threads blocked on the completion port.
1244 *) Bring forward the --suexec-umask option which allows the
1245 builder to preset the umask for suexec processes. [Ken Coar]
1247 *) Add a -V flag to suexec, which causes it to display the
1248 compile-time settings with which it was built. (Only
1249 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1251 *) Mod_include should always unset the content-length if the file is
1252 going to be passed through send_parsed_content. There is no to
1253 determine if the content will change before actually scanning the
1254 entire content. It is far safer to just remove the C-L as long
1255 as we are scanning it. [Ryan Bloom]
1257 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1258 request and not Proxy-Authenticate.
1259 [Graham Leggett <minfrin@sharp.fm>]
1261 Changes with Apache 2.0.14
1263 *) Fix content-length computation. We ONLY compute a content-length if
1264 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1265 or we already have all the data. [Ryan Bloom]
1267 *) Report unbounded containers in the config file. Previously, a typo
1268 in the </container> directive could result in the rest of the config
1269 file being silently ignored, with undesired defaults used.
1272 *) Make the old_write filter use the ap_f* functions for the buffering.
1275 *) Move more code from the http module into the core server. This
1276 is core code, basically the default handler, the default input
1277 and output filters, and all of the core configuration directives.
1278 All of this code is required in order for the server to work, with or
1279 without HTTP. The server is closer to working without the HTTP
1280 module, although there is still more to do. [Ryan Bloom]
1282 *) Fix a number of SGI compile warnings throughout the server. Fix some
1283 bad parameters to apr_bucket_read(). Fix a bad statement in
1284 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1285 consistently; we were mixing apr_time_t and time_t in invalid ways
1286 before. In load_file(), call apr_dso_error() instead of
1287 apr_strerror() so that we get a more specific string on some platforms.
1288 PR #6980 [Jeff Trawick]
1290 *) Allow modules to query the MPM about it's execution profile. This
1291 query API can and should be extended in the future, but for now,
1292 max_daemons, and threading or forking is a very good start.
1293 [Jon Travis <jtravis@covalent.net>]
1295 *) Modify mod_include to send blocks of data no larger than 9k.
1296 Without this, mod_include will wait until the whole file is parsed,
1297 or the first tag is found to send any data to the client.
1298 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1300 *) Fix mod_info, so that <Directory> and <Location> directives are
1301 not displayed twice when displaying the current configuration.
1302 [Ryan Morgan <rmorgan@covalent.net>]
1304 *) Add config directives to override DEFAULT_ERROR_MSG and
1305 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1306 [Dan Rench <drench@xnet.com>]
1308 *) Get mod_info building and loading on Win32. [William Rowe]
1310 *) Begin to move protocol independant functions out of mod_http. The goal
1311 is to have only functions that are HTTP specific in the http directory.
1314 Changes with Apache 2.0.13
1316 *) Don't assume that there will always be multiple calls to the byterange
1317 filter. It is possible that we will need to do byteranges with only
1318 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1320 *) Move the error_bucket definition from the http module to the
1321 core server. Every protocol will need this ability, not just
1324 Changes with Apache 2.0.12
1326 *) Modify mod_file_cache to save pre-formatted strings for
1327 content-length and last-modified headers for performance.
1328 [Mike Abbot <mja@trudge.engr.sgi.com>]
1330 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1331 [Jon Travis <jtravis@covalent.net>]
1333 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1334 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1336 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1337 without ever filling it out. This fixes PR 7271.
1338 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1339 Cliff Woolley <cliffwoolley@yahoo.com>]
1341 *) Add a couple of GCC attribute tags to printf style functions.
1342 [Jon Travis <jtravis@covalent.net>]
1344 *) Add the correct language tag for interoperation with the Taiwanese
1345 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1347 *) Migrate the perchild MPM to use the new apr signal child, and
1348 APR thread functions. [Ryan Bloom]
1350 *) Close one copy of the CGI's stdout before creating the new process.
1351 The CGI will still have stdout, because we have already dup'ed it.
1352 This keeps Apache from waiting forever to send the results of a CGI
1353 process that has forked a long-lived child process.
1354 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1356 *) Remove the rest of the pthreads functions from the threaded MPM.
1357 This requires the APR support for a signal thread that was just
1360 *) Make mod_dir use a fixup for sending a redirect to the browser.
1361 Before this, we were using a handler, which doesn't make much
1362 sense, because the handler wasn't generating any data, it would
1363 either return a redirect error code, or DECLINED. This fits the
1364 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1366 *) Make the threaded MPM use APR threads instead of pthreads.
1369 *) Get mod_tls to the point where it actually appears to work in all cases.
1372 *) implement --enable-modules and --enable-mods-shared for "all" and
1373 "most". [Greg Stein]
1375 *) Move the threaded MPM to use APR locks instead of pthread locks.
1378 *) Rename mpmt_pthread to threaded. This is more in line with the
1379 fact that mpmt_pthread shouldn't be using pthreads directly, and
1380 it is a smaller name that doesn't tie into anything.
1383 *) Rename the module structures so that the exported symbol matches
1384 the file name, and it is easier to automate the installation
1385 process (generating LoadModule directives from the module filenames).
1388 *) Remove the coalesce filter. With the ap_f* functions, this filter
1389 is no longer needed. [Ryan Bloom]
1391 Changes with Apache 2.0.11
1393 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1394 added feature of allowing a uid/gid per child process. If no
1395 uid/gid is specified, then Perchild behaves exactly like dexter.
1398 *) Get perchild building again. [Ryan Bloom]
1400 *) Don't disable threads just because we are using the prefork MPM.
1401 If somebody wants to compile without threads, they must now add
1402 --disable-threads to the configure command line. [Ryan Bloom]
1404 *) Begin to move the calls to update_child_status into common code, so
1405 that each individual MPM does not need to update the scoreboard itself.
1408 *) Allow mod_tls to compile under Unix boxes where openssl has been
1409 installed to the system include files.
1410 [Gomez Henri <new-httpd@slib.fr>]
1412 *) Cleanup the mod_tls configure process. This should remove any need
1413 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1414 configure doesn't check that yet. [Ryan Bloom]
1416 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1417 vital that you read modules/tls/README before attempting to build
1420 *) Fix a potential seg fault on all platforms. David Reid fixed this
1421 on BEOS, but the problem could happen anywhere, so we don't want
1422 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1424 *) Add new LogFormat directive, %D, to log time it takes to serve a
1425 request in microseconds. [Bill Stoddard]
1427 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1428 SetOutputFilter. This corresponds nicely with the other Set
1429 directives, which operate on containers while the Add* directives
1430 tend to work directly on extensions. [Ryan Bloom]
1432 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1433 functions for the buffering so that we don't need to compute
1434 the length of the headers before we actually create the header
1435 buffer. [Ryan Bloom]
1437 *) Allow filters to buffer data using the ap_f* functions. These have
1438 become macros that resolve directly to apr_brigade_*.
1441 *) Get the Unix MPM's to do a graceful restart again. If we are going
1442 to register a cleanup with ap_cleanup_scoreboard, then we have to
1443 kill the cleanup with the same function, and that function can't be
1444 static. [Ryan Bloom]
1446 *) Install all required header files. Without these, it was not
1447 possible to compile some modules outside of the server.
1450 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1451 forward from 1.3 to 2.0, we missed a single line, which broke regex
1452 aliases. [Ryan Bloom]
1454 *) We have a poor abstraction in the protocol. This is a temporary
1455 hack to fix the bug, but it will need to be fixed for real. If
1456 we find an error while sending out a custom error response, we back
1457 up to the first non-OK request and send the data. Then, when we send
1458 the EOS from finalize_request_protocol, we go to the last request,
1459 to ensure that we aren't sending an EOS to a request that has already
1460 received one. Because the data is sent on a different request than
1461 the EOS, the error text never gets sent down the filter stack. This
1462 fixes the problem by finding the last request, and sending the data
1463 with that request. [Ryan Bloom]
1465 *) Make the server status page show the correct restart time, and
1466 thus the proper uptime. [Ryan Bloom]
1468 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1469 should reduce the amount of duplicate code that is required to
1470 create CGI processes.
1471 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1473 *) ap_new_connection() closes the socket and returns NULL if a socket
1474 call fails. Usually this is due to a connection which has been
1475 reset. [Jeff Trawick]
1477 *) Move the Apache version information out of httpd.h and into release.h.
1478 This is in preparation for the first tag with the new tag and release
1479 system. [Ryan Bloom]
1481 *) Begin restructuring scoreboard code to enable adding back in
1482 the ability to use IPC other than shared memory.
1483 Get mod_status working on Windows again. [Bill Stoddard]
1485 *) Make mod_status work with 2.0. This will work for prefork,
1486 mpmt_pthread, and dexter. [Ryan Bloom]
1488 *) Correct a typo in httpd.conf.
1489 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1491 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1493 *) Get the correct IP address if ServerName isn't set and we can't
1494 find a fully-qualified domain name at startup.
1495 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1497 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1499 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1500 'extra' stat's for user/group since they should never occur, and now
1501 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1502 volumes. [William Rowe]
1504 *) Adopt apr features to simplify mod_includes. This changes the
1505 behavior of the USER_NAME variable, unknown uid's are now reported
1506 as USER_NAME="<unknown>" rather than the old user#000 result.
1507 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1509 *) Adopt apr features for simplifing mod_userdir, and accept the new
1510 Win32/OS2 exceptions without hiccuping. [William Rowe]
1512 *) Replace configure --with-optim option by using and saving the
1513 environment variable OPTIM instead. This is needed because configure
1514 options do not support multiple flags separated by spaces.
1517 *) Fix some byterange handling. If we get a byte range that looks like
1518 "-999999" where that is past the end of the file, we should return
1519 a PARTIAL CONTENT status code, and return the whole file as one big
1520 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1522 *) Make the error bucket a real meta-data bucket. This means that the
1523 bucket length is 0, and a read returns NULL data. If one of these
1524 buckets is passed down after the headers are sent, this data will
1525 just be ignored. [Greg Stein]
1527 *) The prefork MPM wasn't killing child processes correctly if a restart
1528 signal was received while the process was serving a request. The child
1529 process would become the equivalent of a second parent process. If
1530 we break out of the accept loop, then we need to do die after cleaning
1531 up after ourselves. [Ryan Bloom]
1533 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1534 restarts. [Ryan Bloom]
1536 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1537 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1538 performing very expensive owner, group and permission lookups
1539 and allows the server to function until these apr_finfo_t fields
1540 are implemented under Win32. [William Rowe]
1542 *) Support for typedsafe optional functions - that is functions exported by
1543 optional modules, which, therefore, may or may not be present, depending
1544 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1545 for sample code. [Ben Laurie]
1547 *) filters can now report an HTTP error to the server. This is done
1548 by sending a brigade where the first bucket is an error_bucket.
1549 This bucket is a simple bucket that stores an HTTP error and
1550 a string. Currently the string is not used, but it may be needed
1551 to output an error log. The http_header_filter will find this
1552 bucket, and output the error text, and then return
1553 AP_FILTER_ERROR, which informs the server that the error web page
1554 has already been sent. [Ryan Bloom]
1556 *) If we get an error, then we should remove all filters except for
1557 those critical to serving a web page. This fixes a bug, where
1558 error pages were going through the byterange filter, even though
1559 that made no sense. [Ryan Bloom]
1561 *) Relax the syntax checking of Host: headers in order to support
1562 iDNS. PR#6635 [Tony Finch]
1564 *) Cleanup the byterange filter to use the apr_brigade_partition
1565 and apr_bucket_copy functions. This removes a lot of very messy
1566 code, and hopefully makes this filter more stable.
1569 *) Remove AddModule and ClearModuleList directives. Both of these
1570 directives were used to ensure that modules could be enabled
1571 in the correct order. That requirement is now gone, because
1572 we use hooks to ensure that modules are in the correct order.
1575 *) When SuExec is specified, we need to add it to the list of
1576 targets to be built. If we don't, then any changes to the
1577 configuration won't affect SuExec, unless 'make suexec' is
1578 specifically run. [Ryan Bloom]
1580 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1581 the APR_XTHREAD argument to open a file for consumption by
1582 parallel threads on win32. [William Rowe]
1584 *) Correct a bug in determining when we follow symlinks. The code
1585 expected a stat -1 result, not an apr_status_t positive error.
1586 Also check if the APR_FINFO_USER fields are valid before we
1587 follow the link. [William Rowe]
1589 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1590 mpm_common.c. These functions are only valid on some platforms,
1591 so they should not be in the main-line code. [Ryan Bloom]
1593 *) Remove ap_chdir_file(). This function is not thread-safe,
1594 and nobody is currently using it. [Ryan Bloom]
1596 *) Do not try to run make depend if there are no .c files in the
1597 current directory, doing so makes `make depend` fail.
1600 *) Update highperformance.conf to work with either prefork or
1601 pthreads mpms. [Greg Ames]
1603 *) Stop checking to see if this is a pipelined request if we know
1604 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1605 This keeps us from making an extra read call when serving a 1.0
1606 request. [Ryan Bloom and Greg Stein]
1608 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1609 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1610 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1612 *) Fix the RFC number mentioned when complaining about a missing
1613 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1615 *) Fix an endless loop in ab which occurred when ab was posting
1616 and the server dropped the connection unexpectedly.
1619 *) Fix a segfault while handling request bodies in ap_http_filter().
1620 This problem has been seen with mod_dav usage as well as with
1621 requests where the body was just being discarded. [Jeff Trawick]
1623 *) Some adjustment on the handling and automatic setting (via
1624 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1625 add the capability to specify flags (NOTEST_CFLAGS and
1626 NOTEST_LDFLAGS) which are used to compile Apache, but
1627 not used during the configuration process. Useful for
1628 flags like "-Werror". [Jim Jagielski]
1630 *) Stop using environment variables to force debug mode or
1631 no detach. We now use the -D command line argument to
1632 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1633 [Greg Stein, Ryan Bloom]
1635 *) Change handlers to use hooks. [Ben Laurie]
1637 *) Stop returning copies of filenames from both apr_file_t and
1638 apr_dir_t. We pstrdup the filenames that we store in the
1639 actual structures, so we don't need to pstrdup the strings again.
1642 *) mod_cgi: Fix some problems where the wrong error value was being
1643 traced. [Jeff Trawick]
1645 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1648 *) Add generic hooks. [Ben Laurie]
1650 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1652 *) Fix a segfault caused by mod_ext_filter when the external filter
1653 program does not exist. [Jeff Trawick]
1655 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1656 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1657 was served through mod_charset_lite (or anything else that would
1658 create a transient bucket in this size range). ap_bucket_make_heap()
1659 silently failed (fixed), transient_setaside() discovered it, but
1660 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1662 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1663 is that some browsers send extra lines at the end of POST requests, and
1664 we don't want to delay sending data back to the user just because the
1665 browser isn't well behaved. [Ryan Bloom]
1667 *) Get SuEXEC working again. We can't send absolute paths to suExec
1668 because it refuses to execute those programs. SuEXEC also wasn't
1669 always recognizing configuration changes made using the autoconf
1672 *) Allow the buildconf process to find the config.m4 files in the correct
1673 order. Basically, we can now name config.m4 files as config\d\d.m4,
1674 and we will sort them correctly when inserting them into the build
1675 process. [Ryan Bloom]
1677 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1678 This also allows mod_cgid to use ap_os_create_priviledged_process,
1679 thus allowing for SuExec execution from mod_cgid. Currently, we do
1680 not support everything that standard SuExec supports, but at least
1681 it works minimally now. [Ryan Bloom]
1683 *) Allow SuExec to be configured from the ./configure command line.
1686 *) Update some of the docs in README and INSTALL to reflect some of
1687 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1689 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1690 need to call sendfile again. This gets us serving large files
1691 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1693 *) Get the support programs building cleanly again.
1694 [Cliff Woolley <cliffwoolley@yahoo.com>]
1696 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1697 current directory logic now backs up over bin/ to determine the
1698 server root from the Apache.exe path.
1700 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1701 loadable modules, dynamic libs are all named libfoo.dll, and the
1702 makefile.win populates the include, lib and libexec directories.
1704 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1705 Apache gets IPv6 listening sockets by default. Additionally, the
1706 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1707 numeric address strings (e.g., "Listen [fe80::1]:8080").
1710 *) Modify the install directory layout. Modules are now installed in
1711 modules/. Shared libraries should be installed in libraries/, but
1712 we don't have any of those on Unix yet. All install directories
1713 are modifyable at configure time. [Ryan Bloom]
1715 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1717 *) Get the functions in server/linked into the server, regardless of
1718 which modules linked into the server. This uses the same hack
1719 for Apache that we use for APR and apr-util to ensure all of the
1720 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1721 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1722 the scripts a bit easier.
1725 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1726 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1728 *) Get all of the auth modules to the point that they will install and
1729 be loadable into the server. Our new build/install mechanism expects
1730 that all modules will have a common name format. The auth modules
1731 didn't use that format, so we didn't install them properly.
1734 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1735 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1737 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1739 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1740 after the end of the response. [Ryan Bloom]
1742 *) Get byterange requests working with responses that do not have a
1743 content-length. Because of the way byterange requests work, we have to
1744 have all of the data before we can actually do the byterange, so we
1745 can compute the content-length in the byterange filter.
1748 *) Get exe CGI's working again on Windows.
1751 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1752 they keep track of whether or not their post config hook has been
1753 called before. Instead of a static variable (which is replaced when
1754 the DSO is loaded a second time), use userdata in the process pool.
1757 Changes with Apache 2.0a9
1759 *) Win32 now requires perl to complete the final install step for users
1760 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1761 and installs the conf, htdocs and htdocs/manual directories.
1764 *) Make mod_include use a hash table to associate directive tags with
1765 functions. This allows modules to implement their own SSI tags easily.
1766 The idea is simple enough, a module can insert it's own tag and function
1767 combination into a hash table provided by mod_include. While mod_include
1768 parses an SSI file, when it encounters a tag in the file, it does a
1769 hash lookup to find the function that implements that tag, and passes
1770 all of the relevant data to the function. That function is then
1771 responsible for processing the tag and handing the remaining data back
1772 to mod_include for further processing.
1773 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1775 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1776 fewer parameters: the local and remote socket addresses were removed
1777 from the parameter list because all required information is available
1778 via the APR socket. [Jeff Trawick]
1780 *) Distribution directory structure reorganized to reflect a
1781 normal source distribution with external install targets.
1784 *) The MPMs that need multiple segments of shared memory now create
1785 two apr_shmem_t variables, one for each shared memory allocation.
1786 the problem is that we can't determine how much memory will be required
1787 for shared memory allocations once we try to allocate more than one
1788 variable. The MM code automatically aligns the shared memory allocations,
1789 so we end up needing to pad the amount of shared memory we want based
1790 on how many variables will be allocated out of the shared memory segment.
1791 It is just easier to create a second apr_shmem_t variable, and two
1792 shmem memory blocks.
1795 *) Cleanup the export list a bit. This creates a single unified list of
1796 functions exported by APR. The export list is generated at configure
1797 time, and that list is then used to generate the exports.c file.
1798 Because of the way the export list is generated, we only export those
1799 functions that are valid on the platform we are building on.
1802 *) Enable logging the cookie with mod_log_config
1803 [Sander van Zoest <sander@covalent.net>]
1805 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1808 *) Added lib/aputil/ as a placeholder for utility functions which are not
1809 specific to the Apache HTTP Server (but do not make sense with APR).
1810 The first utility is "apu_dbm": a set of functions to work with DBM
1811 files. This first version can be compiled for SDBM or GDBM databases.
1814 *) Complete re-write of mod_include. This makes mod_include a filter that
1815 uses buckets directly. This has now served the FAQ correctly.
1816 [Paul Reder <rederpj@raleigh.ibm.com>]
1818 *) Allow modules to specify the first filter in a sub_request when
1819 making the sub_request. This keeps modules from having to change the
1820 output_filter immediately after creating the sub-request, and therefore
1821 skip the sub_req_output_filter. [Ryan Bloom]
1823 *) Update ab to accept URLs with IPv6 literal address strings (in the
1824 format described in RFC 2732), and to build Host header fields in
1825 the same format. This allows IPv6 literal address strings to be
1826 used with ab. This support has been tested against Apache 1.3 with
1827 the KAME patch, but Apache 2.0 does not yet work with this format
1828 of the Host header field. [Jeff Trawick]
1830 *) Accomodate an out-of-space condition in the piped logs and the
1831 rotatelogs.c code, and no longer churn log processes for this
1832 condition. [Victor J. Orlikowski]
1834 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1837 Changes with Apache 2.0a8
1839 *) Add a directive to mod_mime so that filters can be associated with
1843 *) Get multi-views working again. We were setting the path_info
1844 field incorrectly if we couldn't find the specified file.
1847 *) Fix 304 processing. The core should never try to send the headers
1848 down the filter stack. Always, just setup the table in the request
1849 record, and let the header filter convert it to data that is ready
1853 *) More fixes for the proxy. There are still bugs in the proxy code,
1854 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1858 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1861 *) APR: Add new apr_getopt_long function to handle long options.
1862 [B. W. Fitzpatrick <fitz@red-bean.com>]
1864 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1865 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1866 hostname resolution/address string parsing and building
1867 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1868 of one of the apr_sockaddr_t structures for a socket. Change
1869 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1871 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1872 I have proxied pages with it, cleanup will commence soon.
1875 *) Make the proxy work with filters. This isn't perfect, because we
1876 aren't dealing with the headers properly. [Ryan Bloom]
1878 *) Do not send a content-length iff the C-L is 0 and this is a head
1879 request. [Ryan Bloom]
1881 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1882 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1884 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1886 *) Get the default_handler to stop trying to deal with HEAD requests.
1887 The idea is to let the content-length filter compute the C-L before
1888 we try to send the data. If we can get the C-L correctly, then we
1889 should send it in the HEAD response.
1892 *) The Header filter can now determine if a body should be sent based
1893 on r->header_only. The general idea of this is that if we delay
1894 deciding to send the body, then we might be able to compute the
1895 content-length correctly, which will help caching proxies to cache
1896 our data better. Any handler that doesn't want to try to compute
1897 the content-length can just send an EOS bucket without data and
1898 everything will just work.
1901 *) Add the referer to the error log if one is available.
1902 [Markus Gyger <mgyger@itr.ch>]
1904 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1905 change, the root of the configuration tree has been exposed to modules
1907 [Ryan Morgan <rmorgan@covalent.net>]
1909 *) Get the core_output_filter to use the bucket interface directly.
1910 This keeps us from calling the content-length filter multiple times
1911 for a simple static request.
1914 *) We are sending the content-type correctly now.
1915 [Ryan Bloom and Will Rowe]
1917 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1918 a bogus bytes-sent value when the only thing being sent was trailers
1919 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1921 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1922 hints file to determine which platforms define
1923 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1926 *) APR: add apr_get_home_directory() [Jeff Trawick]
1928 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1930 *) Not all platforms have INADDR_NONE defined by default. Apache
1931 used to make this check and define INADDR_NONE if appropriate,
1932 but APR needs the check too, and I suspect other applications will
1933 as well. APR now defines APR_INADDR_NONE, which is always a valid
1934 value on all platforms.
1935 [Branko Èibej <brane@xbc.nu>]
1937 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1938 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1940 *) Relax the syntax checking of Host: headers in order to support
1941 iDNS. PR#6635 [Tony Finch]
1943 *) When reading from file buckets we convert to an MMAP if it makes
1944 sense. This also simplifies the default handler because the
1945 default handler no longer needs to try to create MMAPs.
1948 *) BUFF has been removed from the main server. The BUFF code will remain
1949 in the code until it has been purged from the proxy module as well.
1952 *) Byteranges have been completely re-written to be a filter. This
1953 has been tested, and I believe it is working correctly, but it could
1954 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1955 the output from 1.3, the only difference being that 1.3 includes
1956 a content-length in the response, and this does not.
1959 *) APR read/write functions and bucket read functions now operate
1960 on unsigned integers, instead of signed ones. It doesn't make
1961 any sense to use signed ints, because we return the error codes,
1962 so if we have an error we should report 0 bytes read or written.
1965 *) Always compute the content length, whether it is sent or not.
1966 The reason for this, is that it allows us to correctly report
1967 the bytes_sent when logging the request. This also simplifies
1968 content-length filter a bit, and fixes the actual byte-reporing
1969 code in mod_log_config.c
1972 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1973 it says, because it was only used by EOS and FLUSH buckets. Since
1974 neither of those are required at the end of a brigade, this was
1975 really signifying FLUSH_THE_DATA, but that can be determined better
1976 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1977 buckets now return a length of 0, which is actually the amount of data
1978 read, so they make more sense.
1981 *) Allow the core_output_filter to save some data past the end of a
1982 request. If we get an EOS bucket, we only send the data if it
1983 makes sense to send it. This allows us to pipeline request
1984 responses. As a part of this, we also need to allocate mmap
1985 buckets out of the connection pool, not the request pool. This
1986 allows the mmap to outlive the request.
1989 *) Make blocking and non-blocking bucket reads work correctly for
1990 sockets and pipes. These are the only bucket types that should
1991 have non-blocking reads, because the other bucket types should
1992 ALWAYS be able to return something immediately.
1995 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1996 server, but use Ctrl+Break to initiate a graceful restart
1997 instead of duplicating behavior. [John Sterling]
1999 *) Patch mod_autoindex to set the Last-Modified header based on
2000 the directory's mtime, and add the ETag header. [William Rowe]
2002 *) Merge the 1.3 patch to add support for logging query string in
2003 such a way that "%m %U%q %H" is the same as "%r".
2006 *) Port three log methods from mod_log_config 1.3 to 2.0:
2007 CLF compliant '-' byte count, method and protocol.
2010 *) Add a new LogFormat directive, %c, that will log connection
2011 status at the end of the response as follows:
2012 'X' - connection aborted before the response completed.
2013 '+' - connection may be kept-alive by the server.
2014 '-' - connection will be closed by the server.
2017 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2018 Unicode file names and paths for Win32, and tag the Content-Type
2019 from mod_autoindex to reflect that charset if the the feature
2020 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2022 *) Compute the content length (and add appropriate header field) for
2023 the response when no content length is available and we can't use
2024 chunked encoding. [Jeff Trawick]
2026 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2027 so that content input filters get dechunked data when using
2028 the default handler. Also removed REQUEST_CHUNKED_PASS.
2031 *) Add mod_ext_filter as an experimental module. This module allows
2032 the administrator to use external programs as filters. Currently,
2033 only filtering of output is supported. [Jeff Trawick]
2035 *) Most Apache functions work on EBCDIC machines again, as protocol
2036 data is now translated (again). [Jeff Trawick]
2038 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2039 the EBCDIC support. They are noops on ASCII machines, so this
2040 type of translation doesn't have to be surrounded by #ifdef
2041 CHARSET_EBCDIC. [Jeff Trawick]
2043 *) Fix mod_include. tag commands work again, and the server will
2044 send the FAQ again. This also allows mod_include to set aside
2045 buckets that include partial buckets.
2046 [Ryan Bloom and David Reid]
2048 *) Add suexec support back. [Manoj Kasichainula]
2050 *) Lingering close now uses the socket directly instead of using
2051 BUFF. This has been tested, but since all we can tell is that it
2052 doesn't fail, this needs to be really hacked on.
2055 *) Allow filters to modify headers and have those headers be sent to
2056 the client. The idea is that we have an http_header filter that
2057 actually sends the headers to the network. This removes the need
2058 for the BUFF to send headers.
2061 *) Charset translation: mod_charset_lite handles translation of
2062 request bodies. Get rid of the xlate version of ap_md5_digest()
2063 since we don't compute digests of filtered (e.g., translated)
2064 response bodies this way anymore. (Note that we don't do it at
2065 all at the present; somebody needs to write a filter to do so.)
2068 *) Input filters and ap_get_brigade() now have a input mode parameter
2069 (blocking, non-blocking, peek) instead of a length parameter.
2072 *) Update the mime.types file to the registered media types as
2073 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2076 *) Namespace protect some macros declared in ap_config.h
2079 *) Support HTTP header line folding with input filtering.
2082 *) Mod_include works again. This should still be re-written, but at
2083 least now we can serve an SHTML page again.
2086 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2087 to both the BUFF and the socket in the conn_rec. Functions that
2088 want to use the BUFF can, functions that want to use the socket,
2089 can. They point to the same place.
2092 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2093 [Tomas "Ögren" <stric@ing.umu.se>]
2095 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2096 associated pool goes away. (APR pipes on OS/2 were already had this
2097 logic.) This resolvs a fatal file descriptor leak with CGIs.
2100 *) The final line of the config file was not being read if there was
2101 no \n at the end of it. This was caused by apr_fgets returning
2102 APR_EOF even though we had read valid data. This is solved by
2103 making cfg_getline check the buff that was returned from apr_fgets.
2104 If apr_fgets return APR_EOF, but there was data in the buf, then we
2105 return the buf, otherwise we return NULL.
2108 *) Piped logs work again in the 2.0 series.
2111 *) Restore functionality broken by the mod_rewrite security fix:
2112 rewrite map lookup keys and default values are now expanded
2113 so that the lookup can depend on the requested URI etc.
2114 PR #6671 [Tony Finch]
2116 *) Tighten up the syntax checking of Host: headers to fix a
2117 security bug in some mass virtual hosting configurations
2118 that can allow a remote attacker to retrieve some files
2119 on the system that should be inaccessible. [Tony Finch]
2121 *) Add a pool bucket type. This bucket is used for data allocated out
2122 of a pool. If the pool is cleaned before the bucket is destroyed, then
2123 the data is converted to a heap bucket, allowing it to survive the
2127 *) Add a flush bucket. This allows modules to signal that the filters
2128 should all flush whatever data they currently have. There is no way
2129 to actually force them to do this, so if a filter ignores this bucket,
2130 that's life, but at least we can try with this.
2133 *) Add an output filter for sub-requests. This filter just strips the
2134 EOS bucket so that we don't confuse the main request's core output
2135 filter by sending multiple EOS buckets. This change also makes sub
2136 requests start to send EOS buckets when they are finished.
2139 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2140 makes ap_bucket_destroy a return void, which is okay because it
2141 used to always return APR_SUCCESS, and nobody ever checked its
2142 return value anyway.
2143 [Cliff Woolley <cliffwoolley@yahoo.com>]
2145 *) Remove the index into the bucket-type table from the buckets
2146 structure. This has now been replaced with a pointer to the
2147 bucket_type. Also add some macros to test the bucket-type.
2150 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2151 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2152 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2153 All _VAR_ flavors changes to _DATA to be absolutely clear.
2156 *) Add support for /, //, //servername and //server/sharename
2157 parsing of <Directory> blocks under Win32 and OS2.
2158 [Tim Costello, William Rowe, Brian Harvard]
2160 *) Remove the function pointers from the ap_bucket type. They have been
2161 replaced with a global table. Modules are allowed to register bucket
2162 types and use then use those buckets.
2165 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2166 once we finish writing the request body to the cgi child process;
2167 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2168 worked without this change (for reasons I don't understand), but large
2169 ones didn't. [Jeff Trawick]
2171 *) Remove file bucket specific information from the ap_bucket type.
2172 This has been moved to a file_bucket specific type that hangs off
2173 the data pointer in the ap_bucket type.
2176 *) Input filtering now has a third argument. This is the amount of data
2177 to read from lower filters. This argument can be -1, 0, or a positive
2178 number. -1 means give me all the data you have, I'll deal with it and
2179 let you know if I need more. 0 means give me one line and one line
2180 only. A positive number means I want no more than this much data.
2182 Currently, only 0 and a positive number are implemented. This allows
2183 us to remove the remaining field from the conn_rec structure, which
2187 *) Big cleanup of the input filtering. The goal is that http_filter
2188 understands two conditions, headers and body. It knows where it is
2189 based on c->remaining. If c->remaining is 0, then we are in headers,
2190 and http_filter returns a line at a time. If it is not 0, then we are
2191 in body, and http_filter returns raw data, but only up to c->remaining
2192 bytes. It can return less, but never more.
2193 [Greg Ames, Ryan Bloom, Jeff Trawick]
2195 *) mod_cgi: Write all of the request body to the child, not just what
2196 the kernel would accept on the first write. [Jeff Trawick]
2198 *) Back out the change that moved the brigade from the core_output_filters
2199 ctx to the conn_rec. Since all requests over a given connection
2200 go through the same core_output_filter, the ctx pointer has the
2204 *) Fix another bug in the send_the_file() read/write loop. A partial
2205 send by apr_send would cause unsent data in the read buffer to
2206 get clobbered. Complete making send_the_file handle partial
2207 writes to the network.
2210 *) Fix a couple of type fixes to allow compilation on AIX again
2211 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2213 *) Fix bug in send_the_file() which causes offset to be ignored
2214 if there are no headers to send.
2217 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2218 filter. Useful for supporting Windows 9* with a binary
2219 compiled on Windows NT.
2222 Changes with Apache 2.0a7
2224 *) Reimplement core_output_filter to buffer/save bucket brigades
2225 across multiple calls to the core_filter. The brigade will be
2226 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2227 thresholds are hit or the EOS bucket is received.
2230 *) Create experimental filter (buffer_filter) that coalesces bytes
2231 into one large buffer before invoking the next filter in the
2232 chain. This filter is particularly useful with the current
2233 implementation of mod_autoindex when it inserted above the
2234 chunk_filter. mod_autoindex generates a lot of brigades that
2235 containing buckets holding just a few bytes each. The
2236 buffer_filter coalesces these buckets into a single large bucket.
2239 *) Add apr_sendfile() support into the core_output_filter.
2242 *) Add apr_sendv() support into the core_output_filter.
2245 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2246 [Mike Abbott <mja@sgi.com>]
2248 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2249 make much sense, because Apache uses buckets instead of BUFFs now.
2252 *) send_the_file now falls back to a read/write loop on platforms that
2253 do not have sendfile.
2254 [Ryan Bloom and Brian Havard]
2256 *) Install apachectl correctly, and substitute the proper values so
2257 that it works again. [Ryan Bloom]
2259 *) Better(??) handle platforms that lack sendfile().
2262 *) APR now has UUID generation/formatting/parsing support.
2265 *) Begin the http_filter. This is an input filter that understands
2266 the absolute basic amount required to parse an HTTP Request. The
2267 goal is to be able to split headers from request body before passing
2268 the data back to the other filters.
2271 *) Bring forward from 1.3.13 the config directory implementation
2274 *) install apxs if it is created
2277 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2278 conversions. [William Rowe]
2280 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2281 ap_add_output_filter(). [Jeff Trawick]
2283 *) Multiple build and configuration fixes
2286 -add datadir and localstatedir substitutions
2288 -fix logfilename misspelling
2289 -fix evaluation of installation dir variables and
2290 -replace $foobar by $(foobar) to be usefull in the makefile
2294 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2295 $CC_FOR_BUILD is still missing
2296 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2297 -add missing "AR=@AR@" to severaly Makefile.in's
2298 -cache result for "struct rlimit"
2299 -compile all helper programs with native and cross compiler
2300 and use the native version to generate header file
2301 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2303 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2305 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2307 *) Fix a bug where a client which only sends \n to delimit header
2308 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2309 message. Start working on ebcdic co-existance with input
2311 [William Rowe, Greg Ames]
2313 *) If mod_so is enabled in the server always create libexec, even
2314 if there are no modules installed in this directory. This is a
2315 requirement for APXS to work correctly.
2318 *) Connection oriented output filters are now stored in the
2319 conn_rec instead of the request_rec. This allows us to add the
2320 output filter in the pre-connection phase instead of the
2321 post_read_request phase, which keeps us from trying to write an
2322 error page before we have a filter to write to the network.
2323 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2325 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2326 mmap can be used across multiple buckets (default_handler with
2327 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2328 the mmap itself can't be associated with the bucket.
2331 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2334 *) Radical surgery to improve mod_isapi support under Win32.
2335 Includes a number of newer ServerSupportFunction calls, support
2336 for ReadClient (in order to retrieve POSTs greater than 48KB),
2337 and general bug fixes to more reliably load ISAPI .dll's and
2338 prevent leaking handle resources. Note: There are still
2339 discrepancies between IIS's and Apache's ServerVariables, and
2340 async calls are still not supported. Additional warnings are
2341 logged to facilitate debugging of unsupported ISAPI calls.
2344 *) Add input filtering to Apache. The basic idea for the input
2345 filters is the same as the ideas for output filters. The biggest
2346 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2347 should be called, and the order of execution for the filter itself is
2348 different. When writing an output filter, a brigade is passed in,
2349 and filters operate directly on that brigade, when done, they call
2350 ap_pass_brigade. Input filters are the exact opposite. Because input
2351 is not a push operation, filters first call ap_get_brigade. When this
2352 function returns, the input filter will be left with a valid brigade.
2353 The input filter should then operate on the brigade, and return.
2356 *) Fix building on BSD/OS using its native make. The build system
2357 falls back to the BSD .include directive on that host platform.
2360 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2361 SHA1 and plaintext password encodings. Make feature tests a
2362 bit more flexible. [William Rowe]
2364 *) Charset translation: mod_charset_lite handles output content
2365 translation in a filter. mod_charset_lite no longer ignores
2366 subrequests. A bunch of cruft related to BUFF's support for
2367 translating request and response bodies was removed.
2370 *) Move the addition of the CORE filter to the post_read_request
2371 hook in http_core.c. This removes the need to add the filter in
2372 multiple places and allows for an SSL module to be added much
2373 simpler. [Ryan Bloom]
2375 *) Fix a security problem that affects certain configurations of
2376 mod_rewrite. If the result of a RewriteRule is a filename that
2377 contains expansion specifiers, especially regexp backreferences
2378 $0..$9 and %0..%9, then it may be possible for an attacker to
2379 access any file on the web server. [Tony Finch]
2381 *) Fix a bug where errors that are detected during early request parsing
2382 don't produce visible HTTP error messages at the browser, because
2383 the core_filter wasn't present. [Greg Ames]
2385 *) Provide apr_socklen_t as a portability aid.
2386 [Victor J. Orlikowski]
2388 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2389 as well as a comment arg to the add, adduser and update cmds.
2390 update allows the user to clear or preserve pw/groups/comment.
2391 Fixed a bug in dbmmanage that prevented the check option from
2392 parsing a password followed by :group... text. Corrected the
2393 seed calcualation for Win32 systems, and added -lsdbm support.
2396 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2399 *) Avoid a segfault when parsing .htaccess files. An
2400 uninitialized tree pointer was passed to ap_build_config().
2403 *) Change the way that inet_addr & inet_network are checked for
2404 in APR's configure process to allow BeOS BONE to correctly
2405 find them. With this change BeOS BONE now builds from source
2406 with no problems. [David Reid]
2408 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2409 the end of the parameters to execve() was stored in the wrong
2410 location, overlaying the storage beyond the newargs[] array and
2411 also passing uninitialized storage to execve(), which would
2412 sometimes fail with EFAULT. [Jeff Trawick]
2414 *) Fix a bug parsing configuration file containers. With a sequence
2415 like this in the config file
2417 <IfModule mod_kilroy.c>
2420 <IfModule mod_lovejoy.c>
2425 the second container would be terminated at the blank line due to
2426 sediment in the buffer from reading the prior </IfModule> and an
2427 error message would be generated for the real </IfModule> for the
2428 second container. Also due to this problem, any two characters
2429 could be used for "</" in the close of a container.
2432 *) ap_add_filter prototype changed to remove the ctx pointer. The
2433 pointer still remains in the filter structure, but it can not be
2434 a part of the ap_add_filter prototype. The reason is that when
2435 the core uses AddFilter to add a filter to the stack it doesn't
2436 know how to allocate the ctx pointer, or even how much memory should
2437 be allocated. The filters will have to be responsible for allocating
2438 the ctx memory when they need it.
2441 *) Add an AddFilter directive. This directive takes a list of filters
2442 that should be activated for the requested resource.
2445 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2446 some other platforms). [Jeff Trawick]
2448 *) Modify mod_include to be a filter. Currently, it has only been tested
2449 on actual files, but it should work for CGI scripts too.
2452 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2453 writes. apr_flush() for Unix: handle interrupted writes.
2456 *) NameVirtualHost can now take "*" as an argument instead of
2457 an IP address. This allows you to create a purely name-based
2458 virtual hosting server that does not have any IP addresses in
2459 the configuration file and which ignores the local address
2460 of any connections. PR #5595, PR #4455 [Tony Finch]
2462 *) Fix some compile warnings in mod_mmap_static.c
2463 [Mike Abbott <mja@sgi.com>]
2465 *) Fix chunking problem with CGI scripts. The general problem was that
2466 the CGI modules were adding an EOS bucket and then the core added an
2467 EOS bucket. The chunking filter finalizes the chunked response when it
2468 encounters an EOS bucket. Because two EOS buckets were sent, we
2469 finalized the response twice. The fix is to make sure we only send one
2470 EOS, by utilizing a flag in the request_rec.
2473 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2474 and Win32. Previously, the first read from an apr_file_t set up via
2475 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2477 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2478 bucket, instead of using BUFF's and ap_r*.
2481 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2482 [Mike Abbott <mja@sgi.com>]
2484 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2485 code to use APR file's directly instead of going through BUFFs.
2488 *) Fix compile break on some platforms for mod_mime_magic.c
2489 [John K. Sterling <sterling@covalent.net>]
2491 *) Fix merging of AddDefaultCharset directive.
2492 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2494 *) Minor revamp of the rlimit sections of code. We now test
2495 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2496 is now "available" even if the platform doesn't support
2497 the rlimit family (it's just a noop though). [Jim Jagielski]
2499 *) Migrate the pre-selection of which MPM to use for specific
2500 platforms to hints.m4, which contains (or should contain)
2501 all platform specific "hints". [Jim Jagielski]
2503 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2506 *) Add tables with non-string/binary values to APR.
2509 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2512 *) Update PCRE to version 3.2. [Ryan Bloom]
2514 *) Change the way buckets' destroy functions are called so that
2515 they can be more directly used when changing the type of a
2516 bucket in place. [Tony Finch]
2518 *) Add generic support for reference-counting the resources used by
2519 buckets, and alter the HEAP and MMAP buckets to use it. Change
2520 the way buckets are initialised to support changing the type of
2521 buckets in place, and use it when setting aside TRANSIENT buckets.
2522 Change the implementation of TRANSIENT buckets so that it can be
2523 mostly shared with IMMORTAL buckets, which are now implemented.
2526 Changes with Apache 2.0a6
2528 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2530 *) Add a chunking filter to Apache. This brings us one step closer
2531 to removing BUFF. [Ryan Bloom]
2533 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2534 added to the stack is the last filter to be called. [Ryan Bloom]
2536 *) Apache 2.0 has been completely documented using Scandoc. The
2537 docs can be generated by running 'make docs'. [Ryan Bloom]
2539 *) Add filtered I/O to Apache. This is based on bucket brigades,
2540 Currently the buckets still use BUFF under the covers, but that
2541 should change quickly. The only currently written filter is the
2542 core filter which just calls ap_bwrite. [The Apache Group]
2544 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2545 built with thread support. [Jeff Trawick]
2547 *) Abort configuration if --with-layout was specified and there's
2548 no layout definition file. [Ken Coar]
2550 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2552 *) Add support for extension methods for the Allow response header
2553 field, and an API routine for accessing r->allowed and the
2554 list of extension methods in a unified manner. [Ken Coar]
2556 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2557 [Rob Simonson <simo@us.ibm.com>]
2559 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2560 APACHE_XLATE builds. [Jeff Trawick]
2562 *) A configuration file parsing problem was fixed. When the
2563 configuration file started with an IfModule/IfDefine container,
2564 only the last statement in the container would be retained.
2567 Changes with Apache 2.0a5
2569 *) Perchild is serving pages after passing them to different child
2570 processes. There are still a lot of bugs, but this does work. I
2571 have made requests against the same installation of Apache, and had
2572 different servers use different user IDs to serve the responses.
2573 This change moves to using socketpair instead of an AF_UNIX socket.
2576 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2577 It can't seem to pass between child processes yet, but I think we
2578 are closer now than before. This moves us back to using Unix
2579 Domain Sockets. [Ryan Bloom]
2581 *) libapr functions and types renamed with apr_ prefix.
2582 #include "apr_compat.h" for 1.3.x backwards compat
2585 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2586 return the right information on the local socket address.
2587 [Gregory Nicholls <gnicholls@level8.com>]
2589 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2590 [Gregory Nicholls <gnicholls@level8.com>]
2592 *) Add an option to not detach from the controlling terminal without
2593 going into single process mode. This allows for much easier
2594 debugging of the process startup code. [Ryan Bloom]
2596 *) ab: don't use perror() to report the failure of an APR function.
2599 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2600 scoreboard on graceful restarts.
2603 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2604 An invalid ap_proc_t was passed to ap_create_process().
2607 *) Allow modules to register filters. Those filters are still
2608 never called, but this is a step in the right direction.
2609 [Ryan Bloom and Greg Stein]
2611 *) Register the mod_cgid daemon process for cleanup so that it is
2612 killed at termination if it does not die when the parent gets
2613 SIGTERM. This change is to fix occasional problems where the
2614 process stays around. Bugs in similar logic in mod_rewrite and
2615 mod_include were also fixed. [Jeff Trawick]
2617 *) Fix a bug in the time handling. Basically, we were imploding a time
2618 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2619 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2620 uses those two fields to adjust the time value. Because of the HTTP
2621 spec, both of those values can be zero'ed out safely. This fixes
2622 the bug correctly. [Ryan Bloom]
2624 *) Fix a couple of place in the Windows code where the wrong error
2625 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2627 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2629 *) Added the APR_EOL_STR macro for platform dependent differences in
2630 logfiles and other raw text (such as all APR files). Fixes logfiles
2631 not terminated with cr/lf sequences in Win32. [William Rowe]
2633 *) Move all strings functions in APR to src/lib/apr/strings and create
2634 apr_strings.h for the prototypes. [Ryan Bloom]
2636 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2637 to repeat the syscall until we stop getting EINTR. I noticed a
2638 related problem at termination (SIGTERM) on FreeBSD when using
2639 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2640 implementation work properly with child init. Previously, ap_lock()
2641 was essentially a no-op because all children were using different
2642 locks and thus nobody ever blocked. [Jeff Trawick]
2644 *) The htdocs/ tree has been moved out of the CVS source tree into
2645 a separate area for easier development. This has NO EFFECT on
2646 end-users or Apache installations. [Ken Coar]
2648 *) Integrate the mod_dav module for WebDAV protocol handling. This
2649 adds the dav and dav_fs modules, the SDBM library, and additional
2650 XML handling utilities. [Greg Stein]
2652 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2655 *) Update the lib/expat-lite/ library (bring forward changes from
2656 the Apache 1.3 repository). [Greg Stein]
2658 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2659 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2661 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2662 machines where sendfile is detected, but nobody has written ap_sendfile.
2663 [Dave Hill <ddhill@zk3.dec.com>]
2665 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2667 *) ab would start up more connections than needed, then quit when the
2668 desired number were finished. Also fixed a logic error involving
2669 ab keepalives. [Victor J. Orlikowski]
2671 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2672 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2673 timeouts (i.e, if a timeout was specified, the pipe reverted to
2674 a full blocking pipe). Now the behaviour is more in line with
2675 Unix non-blocking pipes.
2678 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2679 cache open file handles along with accept socket reuse enables
2680 Apache 2.0 to serve non-keepalive requests for static files at
2681 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2682 and Apache 2.0 will serve almost 1200 rps on my system).
2685 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2686 supports two config directives, mmapfile (same behavious as
2687 mod_mmap_static) and cachefile. Use the cachefile directive
2688 to cache open file handles. This directive only works on systems
2689 that have implemented the ap_sendfile API. cachefile works today
2690 on Windows NT, but has not been tested on any flavors of Unix.
2693 *) Cleanup the configuration. With the last few changes the
2694 configuration process automatically:
2695 inherits information about how to build from APR. Allowing
2696 APR to inform Apache that it should or should not use -ldl
2698 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2699 based on the threading model
2701 Apache calls APR's configure process before finishing it's
2702 configuration processing, allowing for more information flow
2707 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2708 with non-zero argument makes the socket non-blocking. BeOS and
2709 OS/2 already worked this way. [Jeff Trawick]
2711 *) ap_close() now calls ap_flush() for buffered files, so write
2712 operations work a whole lot better on buffered files.
2715 *) Fix error messages issued from MPMs which explain where to change
2716 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2719 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2720 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2721 now the way that the blocking state of a pipe is manipulated.
2722 ap_block_pipe() is gone. [Jeff Trawick]
2724 *) Correct the problem where the only local host name that the IP stack
2725 can discover are 'undotted' private names. If no fully qualified
2726 domain name can be identified, the default ServerName will be set to
2727 the machine's IP address string. A warning is always provided if the
2728 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2730 *) Repair problems with config file processing which caused segfault
2731 at init when virtual hosts were defined and which caused ServerName to
2732 be ignored when there was no valid DNS setup. [Jeff Trawick]
2734 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2736 *) Add ap_sendfile implementation for AIX
2737 [Victor J. Orlikowski]
2739 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2740 apr_network_io.h, and apr_thread_proc.h.
2741 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2743 *) Bring the allocation and pool debugging code back into a working
2744 state. This will need to be tested as so far it's only been used on
2747 *) Change configuration command setup to be properly typesafe when in
2748 maintainer mode. Note that this requires a compiler that can initialise
2749 unions. [Ben Laurie]
2751 *) Turn on buffering for config file reads. Part of this was to
2752 repair buffered I/O support in Unix and implement buffered
2753 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2755 *) Win32: Fix problem where UTC offset was not being set correctly
2756 in the access log. Problem reported on news group by Jerry Baker.
2759 *) Fix segfault when reporting this type of syntax error:
2760 "</container> without matching <container> section", where
2761 container is VirtualHost or Directory or whatever.
2764 *) Prevent the source code for CGIs from being revealed when using
2765 mod_vhost_alias and the CGI directory is under the document root
2766 and a user makes a request like http://www.example.com//cgi-bin/cgi
2767 as reported in <news:960999105.344321@ernani.logica.co.uk>
2770 *) Add support for the new Beos NetwOrking Environment (BONE)
2773 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2774 final input char is incomplete; ap_bwrite_xlate() now handles
2775 incomplete final input chars. [Jeff Trawick]
2777 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2778 that a bhalfduplex call occurs before logging or else DNS and
2779 such can delay the last packet of the response. [Dean Gaudet]
2781 *) Some syscall reduction in APR on unix -- don't seek when setting
2782 up an mmap; and don't fcntl() more than once per socket.
2785 *) When mod_cgid is started as root, the cgi daemon now switches
2786 to the configured User/Group (like other httpd processes)
2787 instead of continuing as root. [Jeff Trawick]
2789 *) The prefork MPM now uses an APR lock for the accept() mutex.
2790 It has not been getting a lock at all recently. httpd -V now
2791 displays APR's selection of the lock mechanism instead of the
2792 symbols previously respected by prefork. [Jeff Trawick]
2794 *) Change the mmap() feature test to check only for existence.
2795 The previous check required features not used by Apache.
2798 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2799 sometimes mangled. The len parm to accept() was not
2800 initialized, leading sometimes to an endless loop of failed
2801 accept() calls on OS/390 and anywhere else that failed the call
2802 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2803 instead of declaring it ourselves to fix a compilation problem
2804 on Solaris. [Jeff Trawick]
2806 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2808 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2810 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2812 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2813 initialization if ALLOC_DEBUG is defined; no known symptom
2814 otherwise. [Jeff Trawick]
2816 *) Fix typo in configure script when checking for mod_so. bash
2817 doesn't seem to have a problem but /bin/sh on Solaris does.
2818 Symptom: "./configure: test: unknown operator =="
2821 *) Rebind the Win32 NT and 9x services control into the MPM.
2822 All console, WinNT SCM and Win9x pseudo-service control code is
2823 now wrapped within the WinNT MPM.
2826 *) Make a copy of getenv("PATH") before storing for later use. Some
2827 getenv() implementations use the same storage for successive calls.
2828 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2830 *) Server Tokens work in 2.0 again. This also propogates the change
2831 to allow just the product name in the server string using
2835 Changes with Apache 2.0a4
2837 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2838 won't need to call it. [Greg Ames, Jeff Trawick]
2840 *) Move pre_config hook call to between configuration read and config
2841 tree walk. This allows all modules to implement pre_config hooks
2842 and know that they will be called at an appropriate time.
2845 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2848 *) Add pre-config hooks back to all modules.
2851 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2852 ContentDigest enabled and we can't/don't mmap the file.
2855 *) We now report the correct line number for syntax errors in config
2856 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2858 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2859 related bugs, and changed shmem/locking to use apr API. Shared-mem
2860 is currently disabled, however, because of problems with graceful
2861 restarts. [Ronald Tschalär]
2863 *) Fix corruption of IFS variable in --with-module= handling.
2864 Depending on the user's shell or customization thereof, there
2865 would be errors generating ap_config_auto.h later in the configure
2866 procedure. [Jeff Trawick]
2868 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2869 isn't used (as in 1.3), except that on Unix it is now logged via
2870 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2871 to the error log. [Greg Ames, Jeff Trawick]
2873 *) Add '-D' argument processing for run time configuration defines.
2876 *) Organize http_main.c as independent code, such that no code or
2877 global data is exported from it. WIN32 will dynamically link it
2878 to the server core, so this will prevent mutual dependency.
2881 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2882 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2885 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2886 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2888 *) Add mod_charset_lite for configuring character set translation.
2891 *) Add '-n' option to htpasswd to make it print its user:pw record
2892 on stdout rather than having to frob a text file. [Ken Coar]
2894 *) Fix saferead. Basically, we flush the output buffer if a read on the
2898 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2899 a conversion is single-byte only. [Jeff Trawick]
2901 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2902 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2905 *) Fix some minor errors where pid was being manipulated as an int
2906 instead of the portable pid_t. [Roy Fielding]
2908 *) Fix some error log prints that were printing the pointer to a
2909 structure rather than the pid within the structure.
2910 [Jeff Trawick, Roy Fielding]
2912 *) ab: Fix a command-line processing bug; track bad headers in
2913 err_response; support reading headers up to 2K.
2914 [Ask Bjoern Hansen <ask@valueclick.com>]
2916 *) Fix ap_resolve_env() so that it handles new function added in a prior
2917 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2918 config file.") as well as the constructs used by mod_rewrite.
2919 [Paul Reder <rederpj@raleigh.ibm.com>]
2921 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2923 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2924 APR to perform translation, instead of accessing the hard-coded tables
2925 in 1.3's ebcdic.c. [Jeff Trawick]
2927 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2930 *) Add the ability to hook into the config file reading phase. Basically
2931 if a directive is specified EXEC_ON_READ, then when that directive is
2932 read from the config file, the assocaited function is executed. This
2933 should only be used for those directives that must muck with HOW the
2934 server INTERPRETS the config. This should not be used for directives
2935 that re-order or replace items in the config tree. Those changes should
2936 be made in the pre-config step.
2939 *) Add mod_example to the build system.
2942 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2943 byte character sets. [Jeff Trawick]
2945 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2946 Kraemer and Oliver Reh originally according to the change log).
2949 *) Fix a couple of problems in RFC1413 support (controlled by the
2950 IdentityCheck directive). Apache did not build the request string
2951 properly and more importantly Apache would loop forever if the
2952 would-be ident server dropped the connection before sending a
2953 properly terminated response. [Jeff Trawick]
2955 *) apxs works in 2.0.
2958 *) Reliable piped logs work in 2.0.
2961 *) Introduce a hash table implementation into APR to be used for
2962 replacing tables and other random data structures in Apache.
2965 *) Add some more error reporting to htpasswd in the case of problems
2966 generating or accessing the temporary file. Also, pass in a
2967 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2968 is defined). [Ken Coar]
2970 *) Configure creates config.nice now containing your configure
2971 options. Syntax: ./config.nice [--more-options]
2974 *) Fix various return code problems in APR on Win32. For most of
2975 these, APR was returning APR_EEXIST instead of GetLastError()/
2976 WSAGetLastError(). [Jeff Trawick]
2978 *) Make piped logs work again in version 2.0
2981 *) Add VPATH support to UNIX build system of Apache and APR.
2984 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2988 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2989 Patch submitted to author.
2992 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2993 /sbin in PATH on FreeBSD (all submitted to rse previously)
2996 *) Fix building Pthread-based MPMs on OpenBSD
2997 [Sascha Schumann] PR#26
2999 *) Fix ap_readdir() problem on systems where d_name[] field in
3000 struct dirent is declared with only one byte. (This problem only
3001 affected multithreaded builds.) This caused a segfault during
3002 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3003 least). [Jeff Trawick]
3005 *) Fix some make-portability problems on at least Tru64, Irix
3007 [Sascha Schumann] PR#18, PR#39
3009 *) Add ap_sigwait() to support old-style sigwait() on systems
3010 like OS/390 and UnixWare.
3013 *) Add POSIX-thread flags for more platforms.
3016 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3017 (on Unix, at least) to handle resolver errors. Fix a bug in
3018 the definition of APR_ENOMEM so that ap_strerror() can spit
3019 out the correct error message for it.
3022 Changes with Apache 2.0a3
3024 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3027 *) API: *HOOK* macros now have an AP_ prefix
3030 *) Win32: Eliminate redundant calls to initialize winsock.
3031 [Tim Costello <timcostello@ozemail.com.au>]
3033 *) Fix bugs initializing ungetchar for pipes.
3034 [Chia-liang Kao <clkao@CirX.ORG>]
3036 *) The ab program in the src/support directory is now portable using
3040 *) Support directory is being compiled when the server is built
3043 *) The configure option --with-program-name has been added to allow
3044 developers to rename the executable at configure time. This also
3045 changes the name of the config files to match the executable's name.
3048 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3049 containing version numbers. [Martin Pool]
3051 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3052 Unix; access_log and error_log now created with these perms; non-
3053 Unix is unaffected [Jeff Trawick]
3055 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3056 Replaced more magic numbers with MD5_DIGESTSIZE.
3057 [William Rowe, Roy Fielding]
3059 *) Win32: Get mod_auth_digest compiling and added to the Windows
3060 build environment. Not tested and I'd be suprised if it
3061 actually works. [Bill Stoddard]
3063 *) Revamp the Win32 make environment. Makefiles have been removed and
3064 Apache.dsw created to bring together all the pieces. Create new file
3065 os/win32/BaseAddr.ref to define module base addresses (to prevent
3066 dll relocation at start-up).
3067 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3069 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3070 of the \015, \012, and \015\012 constants with macros.
3071 [Greg Ames <gregames@us.ibm.com>]
3073 *) Add ap_xlate_open() et al for translation of text between different
3074 character sets. The initial implementation requires iconv().
3077 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3078 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3080 *) CGI output is being timed out now.
3083 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3084 is used by the new apr file. There is no reason to create a new file
3085 with the same lifetime as the original file.
3088 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3089 module base addresses. This will help shooting seg faults
3090 in the field. [William Rowe <wrowe@lnd.com>]
3092 *) Update Apache on Windows documentation. Add new document
3093 describing how to compile Apache on Windows.
3094 [William Rowe <wrowe@lnd.com>]
3096 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3097 microseconds instead of seconds. Some storage leaks and other
3098 minor bugs in related code were fixed. [Jeff Trawick]
3100 *) Win32: First cut at getting mod_isapi working under 2.0
3101 [William Rowe <wrowe@lnd.com>]
3103 *) First stab at getting mod_auth_digest working under 2.0
3104 quick change summary:
3105 - moved the random byte generation (ap_generate_random_bytes) into APR
3106 - now uses ap_time_t
3107 - compiles and runs on linux
3109 [Brian Martin <bmartin@penguincomputing.com>]
3111 *) Win32: Move the space stripping of physical service names
3112 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3113 unresolved symbol. Add dependency checking to the
3114 CreateService call to ensure TCPIP and AFP (winsock) is started
3116 [William Rowe <wrowe@lnd.com>]
3118 *) Win32: Add code to perform latebinding on functions that may
3119 not exist on all levels of Windows where Apache runs. This
3120 is needed to allow Apache to start-up on Win95/98. All calls
3121 to non portable functions should be protected with
3122 ap_oslevel checks to prevent runtime segfaults.
3123 [William Rowe <wrowe@lnd.com>]
3125 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3127 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3129 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3130 This addresses PR 1623. Still need to address timing out runaway
3131 CGI scripts. [Bill Stoddard]
3133 *) Win32: Make ap_stat Windows 95/98 friendly
3134 [William Rowe <wrowe@lnd.com>]
3136 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3137 always fail. Need to initialise the dwOSVersionInfoSize member of the
3138 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3141 The patch also enhances ap_get_oslevel (and the associated enum) to
3142 handle selected service packs for NT4, and adds recognition for
3143 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3144 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3145 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3147 *) Get mod_rewrite building and running, and mod_status building for Win NT
3148 [Allan Edwards <ake@raleigh.ibm.com>]
3150 *) Patch to port mod_auth_db to the 2.0 api and also to support
3151 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3152 2.7.7. It should work with version 1 as well but I haven't tested it.
3153 [Brian Martin <bmartin@penguincomputing.com>]
3155 *) Get APR DSO code working under Windows. Includes cross platform
3157 [Tim.Costello@BTFinancialgroup.com]
3159 *) Fix some of the Windows APR time functions.
3162 *) FAQ changes related to tidying up historical documents on the web site.
3163 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3165 *) Move Windows DSO code into APR.
3168 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3169 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3170 at build time. At this point, the server will not compile on Windows because
3171 of the recent DSO commits. Fixing those next.
3172 [Bill Rowe & Bill Stoddard]
3174 *) Added error checking for file I/O APR routines.
3175 [Jon Travis <jtravis@covalent.net>]
3177 *) APR: Don't use the values of resolver error codes for the
3178 corresponding APR error codes. On Unix and Win32, return the
3179 proper APR error code after a resolver error. [Jeff Trawick]
3181 Changes with Apache 2.0a2
3183 *) Renamed the executable back to httpd on all platforms other
3187 *) Allow BeOS to survive restarts, log properly and a few
3188 small things it had problems with due to the way it setup
3189 users and groups. [David Reid]
3191 *) Get mod_rewrite working with APR locks
3192 [Paul Reder <rederpj@raleigh.ibm.com>]
3194 *) Actually remove the sempahore when the lock cleanup routine
3195 is called on BeOS. [David Reid]
3197 *) Clear hook registrations between reads of the config file.
3198 When DSOs are unloaded and re-loaded the old hook pointers may
3199 no longer be valid. This fix eliminates potential segfaults.
3200 [Allan Edwards <ake@raleigh.ibm.com>]
3202 *) Fix a problem with Sigfunc not being defined or bypassed
3203 if sigaction() wasn't found. [Jim Jagielski]
3205 *) Fix the locking mechanism on BSD variants. They now use fcntl
3206 locks. This allows the server to start and serve pages.
3209 *) First cut at getting the Win32 installer to work
3210 [William Rowe <wrowe@lnd.com>]
3212 *) Get htpasswd compiling under Windows
3213 [William Rowe <wrowe@lnd.com>]
3215 *) Change the log message for a bind() failure to show the
3216 interface and port number. [Jeff Trawick]
3218 *) Import the documentation from 1.3.12 and bring parts of it
3219 up-to-date with respect to the changes that have occurred
3223 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3224 now logged correctly on BeOS.
3227 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3228 Makefile.win includes the same user interface as the old
3230 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3232 *) Win32 exec now uses COMSPEC environment string for command
3233 shell path resolution.
3234 [William Rowe <wrowe@lnd.com>] PR#3715
3236 *) Win32: ap_connect() was not returning correct error condition
3238 [Allen Prescott <allen@clanprescott.com>]
3240 *) Win32: ap_open() was broken on Win9x because an NT-specific
3241 flag was passed to CreateFile. ap_puts() added an unnecessary
3243 [Jeff Trawick <trawick@us.ibm.com>]
3245 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3246 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3247 confusing ee/et name and made all extensions language/dialect
3248 rather than country reflecting. Changed example files to
3249 explicit reflect the ISO charset and added a few common
3250 ones to the example config [dirkx]
3252 *) Extend external module capability. To use this, you call
3253 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3256 *) Backported the various "default charset" fixes from 1.3.12,
3257 including the AddDefaultCharset directive. [Jim Jagielski]
3259 *) Added the capability to do ${ENVVAR} constructs in the
3260 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3261 it does this on a line by line basis; i.e. if the envvar
3262 expands to something with spaces you have to protect it
3263 by adding quotes around it (Unless of course you expect it
3264 to contains more than one argument. Alternatively you
3265 can compile it on a per token basis; which is what people
3266 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3267 hampers fancier hacks.
3268 [Dirk-Willem van Gulik]
3270 *) Changed the 'ErrorDocument' syntax in that it NO longer
3271 supports the asymetric
3273 ErrorDocument 301 "Some message
3275 Note the opening " quote, without a closing quote. It now
3276 has either the following syntaxes
3278 ErrorDocument XXX /local/uri
3279 ErrorDocument XXX http://valid/url
3280 ErrorDocument XXX "Some Message"
3282 The recognition heuristic is: if it has a space it
3283 is a message. If it has no spaces and starts with a /
3284 or is a valid URL then treat it that way. Otherwise it
3285 is assumed to be a message.
3287 This breaks backward compatibility but makes live a hell
3288 of a lot easier for GUI's and config file parsers.
3289 [Dirk-Willem van Gulik]
3291 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3292 syntax into a 'on' or 'off' syntax. As it currently is the
3293 only non nesting token which uses NO_ARGS and thus is an
3294 absolute pain for any config interface automation. This
3295 breaks backward compatibility. [Dirk-Willem van Gulik]
3297 *) Add ability to add external modules to the build process. This is
3298 done with --with-module=/path/to/module. Modules can only be added
3299 as static modules at this point.
3302 Changes with Apache 2.0a1
3304 *) Fix FreeBSD 3.3 core dump.
3305 Basically, ap_initialize() needs to get called before
3306 create_process(), since create_process() passes op_on structure
3307 to semop() to get a lock, but op_on isn't initialized until
3308 ap_initialize() calls setup_lock(). Here is a slight
3309 rearrangement to main() which calls ap_initialize() earlier...
3310 [Jeff Trawick <trawick@us.ibm.com>]
3312 *) Enable Apache to use sendfile/TransmitFile API
3313 [Bill Stoddard, David Reid, Paul Reder]
3315 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3319 *) Make file I/O and network I/O writev/sendv APIs consistent.
3320 Eliminate use of ap_iovec_t and use Posix struct iovec.
3321 Use seperate variable on ap_writev to set the number of iovecs
3322 passed in and number of bytes written.
3325 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3326 with ap_create_file_iol(). ap_create_file_iol() requires that
3327 the file be opened prior to the call using ap_open().
3330 *) Port mod_include and mod_cgi to 2.0
3331 [Paul Reder, Bill Stoddard]
3333 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3334 bytes_read/bytes_written is always valid (never -1). Plus
3335 some fixes to buff.c to correct problems introduced by the
3336 errno => ap_status_t changes a while back. Plus a fix to
3337 chunked encoding introduced right at the beginning of 2.0.
3340 *) Revamped UNIX build system to use autoconf and libtool.
3341 [Manoj Kasichainula, Sascha Schumann]
3343 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3345 *) More rigorous checking of Host: headers to fix security problems
3346 with mass name-based virtual hosting (whether using mod_rewrite
3347 or mod_vhost_alias).
3348 [Ben Hyde, Tony Finch]
3350 *) Add back support for UseCanonicalName in <Directory> containers.
3351 [Manoj Kasichainula]
3353 *) Added APLOG_STARTUP log type. This allows us to write an error
3354 message without any of the date and time information. As a part
3355 of this change, I also removed all of the calls to fprintf(stderr
3356 and replaced them with calls to ap_log_error using APLOG_STARTUP
3357 writing to stderr is no longer portable, because we don't direct
3358 stderr to the error log on all platforms.
3361 *) Convert error logging functions to take errno as an argument.
3362 This makes our error logs more portable, because some Windows API's
3363 don't set errno. This change allows us to still output a valid
3364 message on all of our platforms.
3367 *) mod_mime_magic runs in 2.0-dev now.
3368 [Paul Reder <rederpj@raleigh.ibm.com>]
3370 *) sendfile has been added to APR.
3371 [John Zedlewski <zedlwski@Princeton.EDU>]
3373 *) buff.c has been converted to no longer use errno.
3374 [Manoj Kasichainula]
3376 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3377 interface adaption to APR functions did it. [Martin Kraemer]
3379 *) Support DSOs properly on 32-bit HP-UX 11.0
3380 [Dilip Khandekar <dilip@cup.hp.com>]
3382 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3383 [Ralf S. Engelschall]
3385 *) Cleaned APR build environment integration and bootstrap APR
3386 automatically for developers from src/Configure.
3387 [Ralf S. Engelschall]
3389 *) Fixed building of src/support/htpasswd.c
3390 [Ralf S. Engelschall]
3392 *) When generating the Location: header, mod_speling forgot
3393 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3396 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3398 *) Change all pools to APR contexts. This is the first step to
3399 incorporating APR into Apache. [Ryan Bloom]
3401 *) Move "handler not found" warning message to below the check
3402 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3403 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3405 *) Support line-continuation feature in config.option file and
3406 allow the loading of multiple option sections at once via
3407 ``--with-option=<section1>,<section2>,...''
3408 [Ralf S. Engelschall]
3410 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3412 Changes with Apache MPM
3414 *) Use asynchronous AcceptEx() and a completion port to accept and
3415 dispatch connections to threads in Windows NT/2000.
3418 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3421 *) Implement the APACI --with-option facility
3422 (per default used the config.option file).
3423 [Ralf S. Engelschall]
3425 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3427 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3428 Replace pre_connection module call with a register_hook call and
3429 implement pre_connection as a hook. The intent is that these hooks will
3430 be extended to allow Apache to be multi-protocol, and also to allow the
3431 calling order to be specified on a per-hook/per-module basis.
3434 *) Implement mpm_* methods as "modules". Each method gets its own
3435 subdir in src/modules (eg: src/modules/prefork). Selection
3436 of method uses Rule MPM_METHOD. [Jim Jagielski]
3438 *) Port the hybrid server from the apache-apr repository as
3439 mpm_mpmt_pthread. [Manoj Kasichainula]
3441 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3442 amongst the unix MPMs.
3444 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3445 signal handling for the new world order. [Dean Gaudet]
3447 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3448 of alloc.c for now. [Dean Gaudet]
3450 *) Handle partial large writes correctly. [Ben Laurie]
3452 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3453 based on IP/port. [Ben Laurie]
3455 *) Port a bunch of modules to the new module structure.
3456 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3458 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3460 *) Basic restructuring to introduce the MPM concept; includes various
3461 changes to the module API... better described by
3462 docs/initial_blurb.txt. [Dean Gaudet]
3464 Changes with Apache pthreads
3466 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3467 buff operations (generally over a network).
3468 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3470 *) Created http_accept abstraction. Added 4 new functions (not exported):
3471 init_accept(), begin_accepting_requests(), get_request(),
3472 stop_accepting_requests() [Bill Stoddard]
3474 *) Fix to ap_rprintf call that allows mod_info to work properly.
3475 [James Morris <jmorris@intercode.com.au>]
3477 *) user and ap_auth_type fields were moved from connection_rec to
3478 request_rec. [Ryan Bloom]
3480 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3481 needed in a threaded server.
3483 *) Initial pthread implementation from from Dean's apache-nspr code.
3484 [Bill Stoddard, Ryan Bloom]
3487 Changes with Apache 1.3.9
3489 *) Remove bogus error message when a redirect doesn't set Location.
3490 Instead, use an empty string to avoid coredump if the error message
3491 was supposed to include a location. [Roy Fielding]
3493 *) Don't allow configure to include mod_auth_digest unless it is
3494 explicitly requested, even if the user asked for all modules.
3497 *) Translate module names to dll names for OS/2 so that they are no more
3498 than 8 characters long and have an extension of "dll" instead of "so".
3501 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3502 Fix test-compile check to check for randbyte instead of trand32.
3503 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3504 and tweak to make Amaya happier. [Ronald Tschalär]
3506 *) Ensure that the installed expat include files are world readable,
3507 just like the other header files. [Martin Kraemer]
3509 *) Fixed generated AddModule adjustments in APACI's `configure' script
3510 in order to allow (new) modules like mod_vhost_alias to be handled
3511 correctly (which was touched by the adjustments for mod_alias).
3512 [Ralf S. Engelschall]
3514 *) For binary builds, add -R flag to apachectl to work around the lack of
3515 an absolute path to the ./libexec directory where the libhttp.ep file
3516 is needed for SHARED_CORE architectures. [Randy Terbush]
3518 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3519 problem observed by some Win95/98 users where they get CGI script
3520 output sent to the console. [Bill Stoddard]
3522 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3523 routines are now called ap_base64* and are 'plain' (i.e., no
3524 pool access or anything clever). Inside util.c the routines acting
3525 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3526 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3527 now but deprecated. [dirkx]
3529 *) Clean up the base64 and SHA1 additions and make sure they are
3530 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3531 files. [Roy Fielding]
3533 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3534 checking. Allow compiling on VS 6.0. [Randy Terbush]
3536 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3538 *) Use TestCompile to search for the truerand library (rather than blindly
3539 assuming its existence). If it is not found, complain (but do not
3540 exit - yet). [Martin Kraemer]
3542 *) We forgot to add the new exported function names to
3543 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3545 *) Add description of -T command-line option to usage().
3546 [Ralf S. Engelschall]
3548 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3549 searched only AFTER libap has been searched, because libap needs
3550 some symbols from libos. [Martin Kraemer]
3552 *) Fix conflict with original mod_digest related to the symbol of the
3553 module dispatch list (which has to be unique for DSO and follow the
3554 usual conventions for the installation procedure).
3555 [Ralf S. Engelschall]
3557 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3558 for other platforms as well. [Martin Kraemer]
3560 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3561 types by AP_LONG and replace reference to renamed variable 'ubuf'
3562 by 'buffer'. [Martin Kraemer]
3564 Changes with Apache 1.3.8 [not released]
3566 *) Flush the output buffer immediately after sending an error or redirect
3567 response, since the result may be needed by the client to abort a
3568 long data transfer or restart a series of pipelined requests.
3569 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3571 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3572 [Ian Turner <iant@sequent.com>] PR#4735
3574 *) Local struct mmap in http_core.c conflicted with system structure
3575 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3577 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3578 [Ronald Tschalär <ronald@innovation.ch>]
3580 *) Fix a memory leak where the module counts were getting messed
3581 up across restarts. [David Harris <dharris@drh.net>]
3583 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3584 properly in mod_access.
3585 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3587 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3588 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3590 *) PORT: Support for compaq/tandem/com.
3591 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3593 *) Added SHA1 password encryption support to easy migration from
3594 Netscape servers. See support/SHA1 for more information.
3595 Caused the separation of ap_md5.c into md5, sha1 and a general
3596 ap_checkpass.c with just a validate_passwd routine. Added a
3597 couple of flags to support/htpasswd. Some reuse of the to64()
3598 function; hence renamed to ap_to64().
3599 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3601 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3602 with ASCII/EBCDIC conversions in "ident" query.
3603 [David McCreedy <McCreedy@us.ibm.com>]
3605 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3606 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3607 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3609 *) Fix SIGSEGV on some systems because the Vary fix below included
3610 a call to table_do with a variable argument list that was not
3611 NULL terminated. Replaced with better implementation. [Roy Fielding]
3613 Changes with Apache 1.3.7 [not released]
3615 *) The "Vary" response header field is now sanitised right before
3616 the header is sent back to the client. Multiple "Vary" fields
3617 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3618 "Vary: host, negotiate, host, accept-language") are reduced to
3619 single instances. This is a better solution than the force-no-vary
3620 one (which is still valid for clients that can't cope with Vary
3621 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3623 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3625 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3626 least on Linux and FreeBSD for now.
3629 *) Win32: More apache -k restart work. Restarts are now honored
3630 immediately and connections in the listen queue are -not- lost.
3631 This is made possible by the use of the WSADuplicateSocket()
3632 call. The listeners are opened in the parent, duplicated, then
3633 the duplicates are passed to the child. The original listen sockets
3634 are not closed by the parent across a restart, thus the listen queue
3636 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3638 *) Fix handling of case when a client has sent "Expect: 100-continue"
3639 and we are going to respond with an error, but get stuck waiting to
3640 discard the body in the pointless hope of preserving the connection.
3641 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3643 *) Fix 'configure' to work correctly with SysV-based versions of
3644 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3646 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3647 built-in values. Add "-e" option which works like -i but doesn't
3648 install the DSO; useful for editing httpd.conf with apxs. Fix
3649 editing code so that multiple invocations of apxs -a will not
3650 create duplicate LoadModule/AddModule entries; apxs can now be
3651 used to re- enable/disable a module. [Wilfredo Sanchez]
3653 *) Win32: Update the server to use Winsock 2. Specifically, link with
3654 ws2_32.lib rather than wsock32.lib. This gives us access to
3655 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3656 Win 95 users may need to update their TCP/IP stack to pick up
3657 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3658 [Bill Stoddard stoddard@raleigh.ibm.com]
3660 *) Win32: Redirect CGI script stderr (script debug info) into the
3661 error.log when CGI scripts fail. This makes Apache on Win32
3662 behave more like Unix.
3663 [Bill Stoddard stoddard@raleigh.ibm.com]
3665 *) Fixed `httpd' usage display: -D was missing.
3666 [Ralf S. Engelschall] PR#4614
3668 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3669 [Ralf S. Engelschall] PR#4561, PR#4562
3671 *) OS/2: Fix problem with accept lock semaphores where server would die with
3672 "OS2SEM: Error 105 getting accept lock. Exiting!"
3673 [Brian Havard] PR#4505
3675 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3676 [Randy Terbush <randy@covalent.net>]
3678 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3679 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3681 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3682 command potentially _is_ GCC. [Ralf S. Engelschall]
3684 *) Fix apxs build issues on AIX
3685 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3687 *) DocumentRoot Checking: Under previous versions, when Apache
3688 first started up, it used to do a stat of each DocumentRoot to
3689 see if it existed and was a directory. If not, then an error
3690 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3691 does not exist, you will get error messages in error_log. If
3692 the '-t' command line option is used (to check the configuration)
3693 the check of DocumentRoot IS performed. An additional command
3694 line option, '-T', has been added if you want to avoid the
3695 DocumentRoot check even when checking the configuration.
3698 *) Win32: The query switch "apache -S" didn't exit after showing the
3699 vhost settings. That was inconsistent with the other query functions.
3700 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3702 *) Win32: Changed behaviour of apache -k restart.
3703 Previously, the server would drain all connections in the stack's
3704 listen queue before honoring the restart. On a busy server, this
3705 could take hours. Now, a restart is honored almost immediately.
3706 All connections in Apache's queues are handled but connections in
3707 the stack's listen queue are discarded. Restart triggered by
3708 MaxRequestPerChild is unchanged.
3709 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3711 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3712 the accept loop. Good for a 5% performance boost. Cleaned up
3713 parent/child process management code.
3714 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3716 *) Added ceiling on file size for memory mapped files.
3717 [John Giannandrea <jg@meer.net>] PR#4122
3719 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3720 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3721 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3723 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3724 use this at least for Expat. [Ralf S. Engelschall]
3726 *) Allow .module files to specify libraries with Lib:.
3729 *) Allow SetEnvIf[NoCase] to test environment variables as well
3730 as header fields and request attributes. [Ken Coar]
3732 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3733 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3735 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3736 never accepted into any standard, and it opens up certain DoS
3737 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3739 *) TestCompile updated. We can now run programs and output the
3740 results during the Configure process. [ Jim Jagielski]
3742 *) The source is now quad (long long) aware as needed. Specifically,
3743 the Configure process determines the correct size of off_t and
3744 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3745 provides for the 'q' format qualifier (if quads are not available,
3746 'q' is silently "demoted" to long). [Jim Jagielski]
3748 *) When the username or password fed to htpasswd is too long, include the
3749 size limit in the error message. Also report illegal characters
3750 (currently only ':') in the username. Add the size restrictions
3751 to the man page. [Ken Coar]
3753 *) Fixed the configure --without-support option so it doesn't result in
3754 an infinite loop. [Marc Slemko]
3756 *) Piped error logs could cause a segfault if an error occured
3757 during configuration after a restart.
3758 [Aidan Cully <aidan@panix.com>] PR#4456
3760 *) If a "Location" field was stored in r->err_headers_out rather
3761 than r->headers_out, redirect processing wouldn't find it and
3762 the server would core dump on ap_escape_html(NULL). Check both
3763 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3764 if Location isn't set. [Doug MacEachern, Ken Coar]
3766 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3767 of the Expat 1.0.2 distribution. [Greg Stein]
3769 *) Replace regexec() calls with calls to a new API stub function
3770 ap_regexec(). This solves problems with DSO modules which use the regex
3771 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3773 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3774 environment variables can be set according to the protocol version
3775 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3777 *) Add DSO support for OpenStep (Mach 4.2) platform.
3778 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3780 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3781 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3783 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3784 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3786 *) Better DSO flags recognition on NetBSD platforms using ELF.
3787 [Todd Vierling <tv@pobox.com>] PR#4310
3789 *) Always log months in english format for %t in mod_log_config.
3790 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3792 *) Support for server-parsed and multiview-determined ReadmeName and
3793 HeaderName files in mod_autoindex. Removed the restriction on
3794 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3795 routines will deal with the access issues. (It's now possible to
3796 have {site|group|project|customer|...} wide readmes and headers.)
3797 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3800 *) When stat() fails, don't assume anything about the contents of
3801 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3803 *) It's OK for a semop to return EINTR, just loop around and try
3804 again. [Dean Gaudet]
3806 *) Fix configuration engine re-entrant hangups, which solve a
3807 handful of problems seen with mod_perl <Perl> configuration sections
3808 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3810 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3811 by default when building with APACI; allow for platform-specific
3812 variable defaults in configure. [Wilfredo Sanchez]
3814 *) Do setgid() before initgroups() in http_main; some platforms
3815 zap the grouplist when setgid() is called. This was fixed in
3816 suexec earlier, but the main httpd code missed the change.
3817 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3819 *) Add recognition of .tgz as a gzipped tarchive.
3820 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3822 *) mod_include's fsize/flastmod should allow only relative paths, just
3823 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3825 *) OS/2: Add support for building loadable modules using DLLs.
3828 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3831 *) Fix minor but annoying bug with the test for Configuration.tmpl
3832 being newer than Configuration so that it is less likely to fail
3833 when using APACI and shadow sources. [Wilfredo Sanchez]
3835 *) PORT: Add initial support for Mac OS (versions 10.0 and
3836 greater). Use Mac OS X Server layout for now. Clean up dyld code
3837 in unix/os.c, and don't install the dyld error handlers, which
3838 are no longer needed in Mac OS. [Wilfredo Sanchez]
3840 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3841 locations to appropriate ones for user-built (as opposed to
3842 system) installs. [Wilfredo Sanchez]
3844 *) Modify mod_autoindex's handling of AddDescription so that the
3845 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3847 *) Add functionality to the install-bindist.sh script created by
3848 binbuild.sh to use tar when copying distribution files to the
3849 serverroot. This allows upgrading an existing installation
3850 without nesting the new distribution in the old.
3852 install-bindist.sh now detects the local perl5 path to install
3853 apxs and dbmmanage with proper path to perl interpreter.
3855 Add an install-binsupport target which copies the source files
3856 for apxs and dbmmanage to bindist to allow these scripts to
3857 be properly installed relative to the destination serverroot.
3858 [Randy Terbush, Covalent Technologies, randy@covalent.net]

3876 *) Add a directive to allow customising of the tracking cookie name.

3881 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
3883 *) Fixed a bug in mod_dir that causes a child process will infinitely

3885 value of the DirectoryIndex directive is a single dot. Also likely
3886 to happen for anyother values of DirectoryIndex that will map back

3968 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
3970 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
3973 *) Correct an apparent typo: on the Windows and MPE platforms, the
3974 htpasswd utility was limiting passwords to only 8 characters.
3977 *) EBCDIC platforms: David submitted patches for two bugs in the
3978 MD5 digest port for EBCDIC machines:
3979 a) the htdigest utility overwrote the old contents of the digest file
3980 b) the Content-MD5 header value (ContentDigest directive) was wrong
3981 when the returned file was not converted from EBCDIC, but was a
3982 binary (e.g., image file) in the first place.
3983 [David McCreedy <mccreedy@us.ibm.com>]
3985 *) support/htpasswd now permits the password to be specified on the
3986 command line with the '-b' switch. This is useful when passwords
3987 need to be maintained by scripts -- particularly in the Win32
3988 environment. [Ken Coar]
3990 *) Win32: Win32 multiple services patch. Added capability to install and
3991 run multiple copies of apache as individual services.
3994 apache -n apache1 -i -f c:/httpd.conf
3995 Installs apache as service 'apache1' and associates c:/httpd.conf
3998 Starts apache1 service.
4000 Stops apache1 service
4003 apache -n apache2 -i
4004 Installs apache as service 'apache2'. httpd.conf is located under
4005 the default server root (/apache/conf/httpd.conf).
4007 Starts apache2 service.
4010 apache -n apache3 -i -d c:/program files/apache
4011 Install apache as service 'apache3' and sets server root to
4012 c:/program files/apache.
4015 apache -n apache2 -k restart
4016 Restart apache2 service
4018 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
4020 *) Correct the signed/unsigned character handling for the MD5 routines;
4021 mismatches were causing compilation problems with gcc -pedantic and
4022 in the TPF cross-compilation. [Ken Coar]
4024 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4025 a roughly 5 fold speed up. [Brian Havard]
4027 *) proxy ftp: instead of using the hardwired string "text/plain" as
4028 a fallback type for files served by the ftp proxy, use the
4029 ap_default_type() function to determine the configured type.
4030 This allows for special configurations like
4031 <Directory proxy:ftp://some.host>
4032 DefaultType gargle/blurb
4034 Additionally, add the Content-Encoding: header to FTP proxy replies
4035 when the encoding is defined (by the AddEncoding directive).
4036 Because it was missing, it was almost impossible to browse compressed
4037 files using the FTP proxy (works now perfectly in Communicator).
4038 The ftp proxy now also returns the Date: and Server: header lines (if not
4039 much else... This code is "somewhat" broken) like normal requests do.
4042 *) Be more smart in APACI's configure script when determining the UID/GID
4043 for User/Group directives and use the determined UID/GID to initialize
4044 the permissions on the proxycachedir.
4045 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4047 *) Changed the forking-prior-to-cleanup in the proxy module to first
4048 check wether it actually needs to collect garbage. This reduces
4049 the number of fork()s from one/request to just the odd one an hour.
4050 [Dirk-Willem van Gulik]
4052 *) Added proxy, auth and header support to src/support/ab.c. Added a
4053 README file to src/support/
4054 [Dirk-Willem van Gulik]
4056 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
4057 [Ralf S. Engelschall] PR#4050
4059 *) Add support for DSO module compilation on BSD/OS 3.x.
4060 [Randy Terbush, Covalent Technologies]
4062 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
4063 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
4064 option) were substituted with $(TARGET).conf, etc. Same for other strings
4065 with dots where the dot wasn't matched as plain text.
4066 [Ralf S. Engelschall]
4068 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
4070 *) Fix verbose output of APACI configure (option -v)
4071 [Martin Kraemer, Ralf S. Engelschall]
4073 Changes with Apache 1.3.6
4075 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
4077 Changes with Apache 1.3.5 [not released]
4079 *) M_INVALID needed a value within the scope of METHODS so that unknown
4080 methods can be access controlled. [Roy Fielding] PR#3821
4082 *) Added PassAllEnv; makes server's entire environment available
4083 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4085 *) ap_uuencode() always added two trailing '='s and encoding of
4086 8 bit characters on a machine with signed char may produced
4087 incorrect results. Additionally ap_uuencode() should now
4088 work correctly on EBCDIC platforms.
4089 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4091 *) WIN32: Binary installer now runs the configuration DLL before
4092 the reboot prompt (which is only given if MSVCRT.DLL system
4093 DLL is new or updated). This should avoid the configuration
4094 directory being empty after installation. [Paul Sutton]
4095 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
4097 *) WIN32: Binary installer now creates Start menu options to start
4098 and stop Apache as a console application and to uninstall
4099 the Apache service on NT. [Paul Sutton] PR#3741
4101 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
4103 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
4104 have been reported with flock() locking (probably related to kernel
4105 version). [Dean Gaudet] PR#2723, 3531
4107 *) Using APACI, the main config file (usually httpd.conf) was
4108 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
4109 <wsanchez@apple.com>]
4111 *) PORT: AIX does not require the SHARED_CODE "hack"
4112 [Ryan Bloom <rbb@raleigh.ibm.com>]
4114 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
4115 avoidance code added in 1.3.3.
4116 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
4118 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4119 for 8-bit safeness. [Dean Gaudet]
4121 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4122 because SPARCs have a small machine-specific maximum size for the Global
4123 Offset Table which is often exceeded when compiling one of the larger
4124 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4126 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
4127 DSO/DLL section because it's a directive from mod_status and isn't
4128 available before the DLL of mod_status is loaded.
4129 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
4131 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
4132 continuation facility in Apache's configuration files which could
4133 lead to a buffer overflow situation.
4134 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
4136 *) Make documentation and error messages of APACI's --activate-module=FILE
4137 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995
4139 *) Fix the gcc version check (for enabling the `inline' facility) to
4140 really support all future gcc versions >= 2.7 until we know more.
4141 [John Tobey <jtobey@banta-im.com>] PR#3983
4143 *) Let APACI's configure script correctly complain for unknown --enable-XXX
4144 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
4146 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
4147 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
4148 possible buffer overflows. [Ralf S. Engelschall]
4150 *) Remove no longer used non-API function ap_single_module_init().
4151 [Ralf S. Engelschall]
4153 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4156 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4157 to make platform installations easier. [Wilfredo Sanchez]
4159 *) In configure, do not append the target name to the directory path if
4160 the path already contains "apache". [Ralf S. Engelschall]
4162 *) SIGPIPE is now ignored by the server core. The request write routines
4163 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4164 correctly check for output errors and mark the connection as aborted.
4165 Replaced many direct (unchecked) calls to ap_b* routines with the
4166 analogous ap_r* calls. [Roy Fielding]
4168 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4169 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4170 Furthermore map lookups for non-existent keys are now cached as well.
4171 Additionally "txt" maps are now parsed with simple string functions
4172 instead of using ap_pregcomp(). As a side effect a bug that prevented
4173 the usage of keys containing the "," character was fixed.
4174 The changes drastically improve the performance when large rewrite maps
4176 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4178 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4179 other than GET, and const'd the definition of method in request_rec.
4182 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
4184 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4185 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4187 *) Add %V to mod_log_config, this logs the hostname according to the
4188 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4189 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4191 *) Add support for \n and \t to mod_log_config, can be used to produce
4192 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4194 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4196 *) Added informative error messages for failed munmap() and fseek() calls
4197 in http_core.c. [John Bley, Roy Fielding]
4199 *) Added some informative error messages for some failed malloc()
4200 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4202 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4203 is removed. This allows <Directory proxy:*> directives to work and
4204 prevents invalid requests from killing the process.
4205 [Brian Havard <brianh@kheldar.apana.org.au>]
4207 *) Reorganised FAQ document.
4208 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
4210 *) src/support/: The ApacheBench benchmark program was overhauled by
4211 David N. Welton: you can now have it generate an HTML TABLE, presumably
4212 for integration into other HTML sources. David updated the ab man page
4213 as well and added some missing descriptions. Thanks!
4214 [David N. Welton <davidw@prosa.it>]
4216 *) Win32: The filename validity checker now allows filenames containing
4217 characters in the range 0x80 to 0xff (for example accented characters).
4218 [Paul Sutton] PR#3890
4220 *) Added conditional logging based upon environment variables to
4221 mod_log_config. mod_log_referer and mod_log_agent
4222 are now deprecated. [Ken Coar]
4224 *) Allow apache acting as a proxy server to relay the real
4225 reason of a failure to a client rather than the "internal
4226 server error" it does currently. The general exposure mechanism
4227 can be triggered by any module by setting the "verbose-error-to"
4228 note to "*"; this allows more than just proxy errors to be exposed.
4229 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4231 *) Moved man pages for ab and apachectrl to section 8.
4232 [Wilfredo Sanchez, Roy Fielding]
4234 *) Added -S option to install.sh so that options can be passed to
4235 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4237 *) Tweak modules Makefile generated by Configure so that it handles
4238 the test case of no modules being selected. [chaz@reliant.com]
4240 *) Added a <LimitExcept method ...> sectioning directive that allows
4241 the user to assign authentication control to any HTTP method that
4242 is *not* given in the argument list; i.e., the logical negation
4243 of the <Limit> directive. This is particularly useful for controlling
4244 access on methods unknown to the Apache core, but perhaps known by
4245 some module or CGI script. [Roy Fielding, Tony Finch]
4247 *) Prevent apachectl from complaining if the PIDFILE exists but
4248 does not contain a process id, as might occur if the server is
4249 being rapidly restarted. [Wilfredo Sanchez]
4251 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4253 *) Entity tag comparisons for If-Match and If-None-Match were not being
4254 performed correctly -- weak tags might cause false positives. Also,
4255 strong comparison wasn't properly enforced in all cases.
4256 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4258 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4261 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4262 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4264 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4265 to util.c for parsing an HTTP header field value to extract the next
4266 list item, taking into account the possible presence of nested comments,
4267 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4268 insignificant whitespace and lowercases non-quoted tokens.
4269 [Roy Fielding] PR#2065
4271 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4272 code different from 500. This allows the proxy to, e.g., return
4273 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4275 *) Fix ordering of language variants for the case where the traditional
4276 negotiation algorithm is being used with multiple language variants
4277 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4279 *) Do not round the TCN quality calculation to 5 decimal places,
4280 unlike RFC 2296, because the calculation might need 12 decimal places
4281 to get the right result. [Roy Fielding]
4283 *) Remove unused code to disable transparent negotiation when
4284 negotiating on encoding only, as we now handle encoding too
4285 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4286 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4287 some debugging statements within mod_negotiation. [Koen Holtman]
4289 *) Fixed a rare memory corruption possibility in mod_dir if the index
4290 file is negotiable and no acceptable variant can be found.
4291 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4293 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4294 searching the Win32 registry for script interpreters.
4297 *) Win32: The compiled-in default filename for the error log is now
4298 error.log, which matches the default in the distributed httpd.conf.
4301 *) Win32: Any error messages from -i or -u command line options are now
4302 displayed on the console output rather than sent to the error log.
4303 Also the "Running Apache..." message is not output unless Apache is
4304 going to serve requests. [Paul Sutton]
4306 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4307 and use a private significator ('$apr1$') to mark passwords as
4308 being smashed with our own algorithm. Also abstract the password
4309 checking into a new ap_validate_password() routine. [Ken Coar]
4311 *) Win32: The filename validity checker now allows "COM" but refuses
4312 access to "COM1" through "COM4". This allows filenames such
4313 as "com.name" to be served. [Paul Sutton] PR#3769.
4315 *) BS2000: Adapt to the new ufork() system call interface which will
4316 make subtasking easier on the OSD/POSIX mainframe environment.
4319 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4320 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4322 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4323 use `.db' instead of `.pag' not only for FreeBSD, but also when
4324 the NDBM library looks like Berkeley-DB based.
4325 [Ralf S. Engelschall] PR#3773
4327 *) Add ability to handle DES or MD5 authentication passwords.
4328 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4330 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4332 *) SECURITY: Avoid some buffer overflow problems when escaping
4333 quoted strings. (This overflow was on the heap and we believe
4334 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4336 *) Let src/Configure be aware of CFLAGS options starting with plus
4337 signs as it's the case for the HP/UX compiler.
4338 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4340 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4341 and check to see if the tar we wind up with supports '-h'.
4342 [Jim Jagielski] PR#3671
4344 *) A consistent and conservative style for all shell scripts has been
4345 implemented. Basically, all shell string tests use the traditional
4346 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4347 to protect against bare null variable strings (ie: wrapping both
4348 sides with double quotes and prepending 'x'). 'x' was chosen
4349 because it's more universal and hopefully easier for old shell
4350 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4353 *) The status module now prints out both the main server generation as
4354 well as the generation of each process. Also, the vhost info is
4355 printed with '?notable'. [Jim Jagielski]
4357 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4358 and this makes its functions available to things in src/support.
4361 Changes with Apache 1.3.4
4363 *) Renamed macros status_drops_connection to ap_status_drops_connection
4364 and vestigial scan_script_header to ap_scan_script_header_err,
4365 mostly for aesthetic reasons. [Roy Fielding]
4367 *) The query switch "httpd -S" didn't exit after showing the
4368 vhost settings. That was inconsistent with the other query functions.
4371 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4372 filename to the end of the STANDARD_MODULE_STUFF. Its
4373 presence at the beginning prevented reporting of the filename
4374 for modules compiled before 1 January 1999. [Ken Coar]
4376 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4377 to detect and prevent access to special DOS device file names.
4378 [Paul Sutton, Ken Parzygnat]
4380 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4381 and Makefile_win32_debug.txt (debug build) that work on Win95.
4382 Run each of the following from the src directory:
4383 nmake /f Makefile_win32.txt # compiles normal build
4384 nmake /f Makefile_win32.txt install # compiles and installs
4385 nmake /f Makefile_win32.txt clean # removes compiled junk
4386 nmake /f Makefile_win32_debug.txt # compiles debug build
4387 nmake /f Makefile_win32_debug.txt install
4388 nmake /f Makefile_win32_debug.txt clean
4391 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4392 to build binary distributions. [Lars Eilebrecht]
4394 *) IndexOptions SuppressColumnSorting only turned off making
4395 the column headers anchors; you could still change the display
4396 order by manually adding a '?N=A' or similar query string to the
4397 URL. Now SuppressColumnSorting locks in the sort order so
4398 it can't be overridden this way. [Ken Coar]
4400 *) Added IndexOrderDefault directive to supply a default sort order
4401 for FancyIndexed directory listings. [Ken Coar] PR#1699
4403 *) Change the ap_assert macro to a variant that works on all platforms.
4404 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4406 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4407 search for an underscore on dlsym() (as it's already the case
4408 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4410 *) Small fix for mod_env.html: The module was documented as to be _not_
4411 compiled into Apache per default, although it _IS_ compiled into
4412 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4414 *) Instead of fixing a bug in the generation procedure for config.status (a
4415 backslash was missing) we remove the bug together with it's complete
4416 context because the special cases of the past can now no longer occur
4417 because of the recent magic for the --with-layout default.
4418 [Ralf S. Engelschall] PR#3590
4420 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4421 making sure the src/support/ tools are _forced_ to be build last (they
4422 depend on other libraries).
4423 [Markus Theissinger <markus.theissinger@gmx.de>]
4425 *) Fix installation procedure: Now that os-inline.c is actually used (a
4426 recently fixed bug prevented this) we need to also install os-include.c
4427 in addition to os.h into the PREFIX/include/ location or building of
4428 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4430 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4431 allow us to distinguish between a garbled DSO (or even a file which isn't
4432 an Apache module DSO at all) and a DSO which doesn't match the current
4433 Apache API. [Ralf S. Engelschall] PR#3152
4435 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4436 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4437 match case insensitive (this especially avoids nasty patterns like
4438 `[tT][eE][sS][tT]'). Second two additional internal map functions
4439 `escape' and `unescape' were added which can be used to escape/unescape
4440 to/from hex-encodings in URLs parts (this is especially useful in
4441 combination with map lookups).
4442 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4444 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4445 forgotten (because it was a macro) in the symbol renaming process.
4446 [Ralf S. Engelschall]
4448 *) Fix some inconsistencies related to the scopes of directives. The only
4449 user visible change is that the directives `UseCanonicalName' and
4450 `ContentDigest' now use the (more correct) `Options' scope instead of
4451 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4453 *) Using DSO, the Server token was being mangled. Specifically, the
4454 module's token was being added first before the Apache token. This
4455 has been fixed. [Jim Jagielski]
4457 *) Major overhaul of mod_negotiation.c, part 2.
4458 - properly handle "identity" within Accept-Encoding.
4459 - allow encoded variants in RVSA negotiation and let them appear in
4460 the Alternates field using the non-standard "encoding" tag-list.
4461 - fixed both negotiation algorithms so that an explicitly accepted
4462 encoding is preferred over no encoding if "identity" is not
4463 included within Accept-Encoding.
4464 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4465 of large substring sequences.
4466 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4469 *) Major overhaul of mod_negotiation.c, part 1.
4470 - cleanups to mod_negotiation comments and code structure
4471 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4472 support for everything in the upcoming HTTP/1.1
4473 revision (draft-ietf-http-v11-spec-rev-06.txt).
4474 - language tag matching also handles tags with more than 2
4476 - empty Accept, Accept-Language, Accept-Charset headers are
4477 processed correctly; previously an empty header would make all
4478 values acceptable instead of unacceptable.
4479 - allowed for q values in Accept-Encoding
4480 - added support for transparent content negotiation (rfc2295 and
4481 rfc2296) (though we do not implement all features in these drafts,
4482 e.g. no feature negotiation). Removed old experimental version.
4483 - implemented 'structured entity tags' for better cache correctness
4484 (structured entity tags ensure that caches which can deal with Vary
4485 will (eventually) be updated if the set of variants on the server
4487 - this involved adding a vlist_validator element to request_rec
4488 - this involved adding the ap_make_etag() function to the global API
4489 - modified guessing of charsets used by Apache negotiation algorithm
4490 to guess 'no charset' if the variant is not a text/* type
4491 - added code to sort multiviews variants into a canonical order so that
4492 negotiation results are consistent across backup/restores and mirrors

4521 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4524 *) Update APXS manual page: some -q option arguments were missing
4525 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4527 *) Cleanup the command line options: `-?' was documented to show
4528 the usage list but does it with an error because `?' is not a valid
4529 command. OTOH a lot of users expect `-h' to print such a usage list and
4530 instead are annoyed for ages by our huge unreadable list of directives.
4531 So we now changed the command line options this way:
4533 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4534 very similar to the popular linker option.
4536 Intent: while -l gives the small list of modules, -L now gives the
4537 large list of directives implemented by these modules. This is also
4538 consistent with -v (short version info) and -V (large version info).
4540 Intent: it's now the expected option ;-)
4541 The manual page was adjusted accordingly.

4545 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4547 *) Removed recently introduced bugs and disfigurements in APACI:
4548 o fixed argument line processing: using $args was broken: It was not
4549 initialized and using args="$args $apc_option" and even args="$args
4550 \"$apc_option\"" fails in the second processing round for any arguments
4551 containing whitespaces. The only correct way is to use the construct
4552 "$@" (but not possible here) or iterate _both_ times over the implicit
4553 argument line (no argument to for-loop) which is what we now use.
4554 o make --with-layout=Apache the default without creating
4555 redundancy (copying the --with-layout block in the argument parsing
4556 loop). We achieve this by using the "$@" construct together with the
4557 `set' command to prepend --with-layout=Apache to the command line in
4558 case --with-layout is not used.
4559 o fixed auto-suffix handling now that config.layout exists.
4560 Paths which are auto-suffixed are marked with a trailing plus sign in
4561 config.layout and every path now can be marked this way (not only the
4562 four paths for which we do it currently). Additionally the suffix is
4563 no longer a static one. Instead it's now `/<target>' where <target> is
4564 the argument of the --target option or per default `httpd'.
4565 o allow also tabs (and only spaces) where we match whitespaces
4566 o various fixes and cleanups related to used shell coding style
4567 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4568 o trimmed output of --help to fit into 80 columns

4631 procedure of mod_rewrite: very long keys were truncated.

4635 identifier, currently "Apache" and "GNU" are pre-defined in the file
4636 config.layout. Custom layouts are possible by using FILE:ID as the
4637 argument where the layout ID is taken from FILE.
4639 The config.layout file consists of <Layout ID>..</Layout> sections
4640 where inside those sections "path_variable: path_value" pairs can be
4641 specified. These lines are converted to path_variable='path_value'.
4643 *) Add a DefaultLanguage directive so that files missing a language
4644 extension (e.g., .fr, .de) can be labelled as being some other
4645 default language. DefaultLanguage can appear in <Directory> and
4646 <Files> containers as well as .htaccess files. [Paul Sutton]

4961 mod_auth_db to both be friendly to users who wants to use this version
4962 and to avoid problems under platforms where only version 2.x is present.
4963 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
4965 *) When using ap_log_rerror(), make the error message available to the
4966 *ERROR_NOTES envariables by default. [Ken Coar]
4968 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
4969 You now must define a BS2000Account name for the server User.
4970 This has fewer security implications than the old approach.
4973 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4974 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4975 platform to make the braindead HPUX linker happy. Notice, for the module
4976 DSOs we don't have to use this, because these are loaded manually (and
4977 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
4979 *) Remove 64 thread limit on Win32.

4986 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
4988 *) Make PrintPath work generically instead of having one version
4989 strictly for OS/2. [Jim Jagielski, Brian Havard]
4991 *) Fix the recently introduced C header file checking: We now use the C
4992 pre-processor pass only (and no longer the complete compiler pass) to
4993 determine whether a C header file exists or not. Because only this way
4994 we're safe against inter-header dependencies (which caused horrible
4995 portability problems). The only drawback is that we now have a CPP
4996 configuration variable which has to be determined first (we do a similar
4997 approach as GNU Autoconf does here). When all fails the user still has
4998 the possibility to override it manually via APACI or src/Configuration.
4999 As a fallback for the header check itself we can directly check the
5000 existance of the file under /usr/include, too.

5034 -msym is just to optimize the DSO statup time a little bit it's safe and
5035 best when we leave it out now. [Ralf S. Engelschall] PR#2969

5039 "%" chars and second ap_log_printf() no longer does a double-formatting

5041 real internal formatting function). [Ralf S. Engelschall] PR#2941
5043 *) Allow "Include" directives anywhere in the server config

5048 directive allows the configuration of the ports to which a
5049 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5051 *) mod_expires will now act on content that is not sent from a file
5052 on disk. Previously it would never add an Expires: header to
5053 any response that did not come from a file on disk; the only
5054 case where it still doesn't (and can't) add one for that type of
5055 content is if you are using a modification date based setting.

5067 *) Recognize lowercase _and_ uppercase `uname' results under

5070 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
5071 a common problem of (mis-administrated?) IIS servers, make the apache
5072 proxy immune to these errors (and ignore the duplicates, but log
5073 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5075 *) The <IfModule and <IfDefine block starting directives now only
5076 allow exactly one argument. Previously, the optional negation
5077 character '!' could be separated by whitespace without a syntax
5078 error being reported, albeit defeating the IfModule functionality
5079 (enclosed directives would ALWAYS be executed). By using the
5080 stricter syntax, these hard-to-track errors can be avoided.
5083 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5084 cause the standalone FancyIndexing directive to logically OR
5085 into any existing IndexOptions settings rather than wiping
5086 them out. [Ken Coar]
5088 *) Changes in ftp proxy: make URL parsing simpler by using the
5090 + Add display of the "current directory" in cases where it's
5091 different from the supplied path (e.g., ftp://user@host/ lives
5092 in /home/user, not in /, therefore clicking on "../" in the
5093 starting directory might send us to /home/).
5094 + When ftp login fails, (esp. when a user name was part of the
5095 URL already), we now return [401 Unauthorized ] to allow the
5096 browser to pop up an authorization dialog. This makes passwords
5097 slightly less visible (they don't appear in the regular log files)
5098 and implements a functionality that other www proxy servers
5102 *) Triggered by the recent "Via:" header changes, the proxy module would
5103 dump core for replies with invalid headers (e.g., duplicate
5104 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5105 core dump is avoided. Also, broken replies are not cached.

5115 *) Replace the inlined information grabbing stuff for the configuration
5116 adjustment feature (no --without-confadjust) with calls to a new helper
5117 script `buildinfo.sh' which is both more flexible and already proofed to
5118 be more robust against platform differences. This mainly fixes the

5140 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
5141 5 to 10 because there are some users out there who always have 5 to 8
5142 variables in one RewriteRule and had to patch mod_rewrite.h for every

5144 needed more than 4 in my RewriteRules ;-)

5169 *) When READing a request in ExtendedStatus mode, the "old"
5170 vhost, request and client information is not displayed.
5173 *) STATUS is no longer available. Full status information now
5174 run-time configurable using the ExtendedStatus directive.
5177 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5178 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5179 a function which can be used to perform bulk update operations
5180 on tables in a more efficient manner. [Dean Gaudet]
5182 *) SECURITY: Added compile-time and configurable limits for
5183 various aspects of reading a client request to avoid some simple
5184 denial of service attacks, including limits on maximum request-line
5185 size (LimitRequestLine), number of header fields (LimitRequestFields),
5186 and size of any one header field (LimitRequestFieldsize). Also added
5187 a configurable directive LimitRequestBody for limiting the size of the
5188 request message body. [Roy Fielding]

5207 state even without full STATUS accounting. [Jim Jagielski]
5209 *) Restore the client IP address to the error log messages, this
5210 was lost during the transition from 1.2 to 1.3. Add a new
5211 function ap_log_rerror() which takes a request_rec * and
5212 formats it appropriately. [Dean Gaudet] PR#2661
5214 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
5215 whitespace in input lines -- including within quoted strings.
5217 but leading and trailing whitespace should continue to be
5218 stripped [Martin Kraemer]
5220 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
5221 the ugly use of an env. variable and use command-line args for
5222 alternate $PATH. Make more like advanced 'type's as well.
5225 *) The IRIXN32 Rule was being ignored. Configure now correctly adds

5233 directory was renamed to src/os/os2/ for consistency.
5234 [Brian Havard, Ralf S. Engelschall]
5236 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5237 files (here modules) against other DSO files (here shared libraries).
5238 This is done by determining a subset of LIBS which can be safely used for
5239 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5240 disabled for all platforms to avoid problems with this (experimental)
5241 rule. But we provide it now for those people how ran into problems and
5242 want to came out by forcing linking against DSOs.

5461 *) Fix the Guess-DSO-flags-from-Perl stuff in src/Configure: "perl" was
5462 used instead of "$PERL" which contains the correctly determined Perl
5463 interpreter (important for instance on systems where "perl" and "perl5"
5464 exists, like BSDI or FreeBSD, etc).
5465 [Ralf S. Engelschall] PR#2505
5467 *) Move the initial suEXEC-related startup message from plain
5468 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
5469 when Apache is started from inetd (instead of standalone). Under this
5470 situation startup messages on stderr lead to problems (the line is sent
5471 to the client in front of the requested document).
5472 [Ralf S. Engelschall] PR#871, PR#1318
5474 *) Add a flag so ap_fnmatch() can be used for case-blind pattern matching.

5478 [Ben Laurie, Bill Stoddard <wgstodda@us.ibm.com>] PR#2274
5480 *) WIN32 SECURITY: Eliminate trailing "."s in path components. These are
5481 ignored by the Windows filesystem, and so can be used to bypass security.
5482 [Ben Laurie, Alexei Kosut].
5484 *) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
5486 *) PORT: remove broken test for MAP_FILE in http_main.c.
5487 [Wilfredo Sanchez <wsanchez@apple.com>]
5489 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
5490 httpd is running. This should be more portable than figuring out
5491 which of three dozen different versions of "ps" are installed.
5494 *) WIN32: If we can't figure out how to execute a file in a script
5495 directory, bail out of the request with an error message. [W G Stoddard]
5497 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
5498 these are treated by Win32 as if they are ".." but are not detected by
5499 other machinery within Apache. This is something of a kludge but
5500 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5502 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5503 pools and thus pollutes libap (until the pool stuff is moved there).
5506 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
5507 but case-insensitive platforms). New #define for this added to conf.h
5508 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
5510 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
5511 also works for OpenBSD 1.x. [Ralf S. Engelschall]
5513 *) PORT: Fix compilation problem on ARM Linux.
5514 [Sam Kington <sam@illuminated.co.uk>] PR#2443
5516 *) Let APACI's configure script determine some configuration parameters
5517 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5518 remove some of the classical hurdles for new users when setting up
5519 Apache. This is done per default because it is useful for the average
5520 user. Package authors can use the --without-confadjust option to disable
5521 these configuration adjustments.
5522 [Ralf S. Engelschall]
5524 *) Added an EXTRA_DEPS configuration parameter which can be used
5525 to add an extra Makefile dependency for the httpd target, for instance
5526 to external third-party libraries, etc.
5527 [Ralf S. Engelschall]
5529 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5530 as <IfModule>..</IfModule> sections) which can be used to skip or process
5531 contained commands dependend of ``-D PARAMETER'' options on the command
5532 line. This can be used to achieve logical conditions like <IfDefine
5533 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5534 and thus especially can be used for conditionally loading DSO-based
5535 modules via LoadModule, etc. [Ralf S. Engelschall]
5537 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
5539 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
5541 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
5542 truncated which forced following HTTP headers to be data in the HTTP
5543 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5546 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5547 in top-level configure script to avoid sed fails on some platforms (for
5548 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5549 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5551 *) Improve performance of directory listings (mod_autoindex) by comparing
5552 integer keys (last-modified and size) as integers rather than converting
5553 them to strings first. Also use a set of explicit byte tests rather
5554 than strcmp() to check for parent directory-ness of an entry. Oh, and
5555 make sure the parent directory (if displayed) is *always* listed first
5556 regardless of the sort key. Overall performance winnage should be good
5557 in CPU time, instruction cache, and memory usage, particularly for large
5558 directories. [Ken Coar]
5560 *) Add a tiny but useful goody to APACI's configure script: The generation
5561 of a config.status script (as GNU Autoconf does) which remembers the used
5562 configure command and hence can be used to restore the configuration by
5563 just re-running this script or for remembering the configuration between
5565 [Ralf S. Engelschall]
5567 *) Add httpd -t (test) option for running configuration syntax tests only.
5568 If something is broken it complains and exits with a return code
5569 non-equal to 0. This can be used manually by the user to check the Apache
5570 configuration after editing and is also automatically used by apachectl
5571 on (graceful) restart command to make sure Apache doesn't die on restarts
5572 because of a configuration which is now broken since the last (re)start.
5573 This way `apachectl restart' can be used inside cronjobs without having
5574 to expect Apache to be falling down. Additionally the httpd -t can be run
5575 via `apachectl configtest'.

5601 didn't match). [Ralf S. Engelschall]
5603 *) Add an additional "dummy" target to the "$(LIB)" target in generated

5709 *) Propagate environment to CGI scripts correctly in Win32.
5710 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
5712 *) Some symbol renaming:
5713 ap_spawn_child_err became ap_spawn_child
5714 ap_spawn_child_err_buff became ap_bspawn_child
5715 spawn_child was obsoleted and moved to compat.h
5718 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5719 programs: ap_spawn_child_err() is used and the Win32 case now uses
5720 CreateProcess() instead of a low-level execl() (which caused problems in
5721 the past under Win32).
5722 [Ralf S. Engelschall]
5724 *) A few cosmetics and trivial enhancements to APXS to make the
5725 generated Makefile more user friendly. [Ralf S. Engelschall]
5727 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5728 was updated to use the normal apache error processing, thereby allowing
5729 proxy errors to be treated by ErrorDocument's as well. For this
5730 purpose, a new module-to-core communication variable "error-notes"
5731 was introduced; the proxy (and possibly other modules) communicates
5732 its error text using this variable. Its content is copied to a new
5733 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5734 The old proxy special error routine ap_proxy_log_uerror()
5735 was replaced by regular ap_log_error() calls, many messages were made
5737 [Martin Kraemer] PR#494, 1259
5739 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5742 *) Transform the configure message "You need root privileges for suEXEC"
5743 from a fatal error into a (more friendly) warning because the building
5744 ("make") of Apache we can allow, of course. Root privileges are needed
5745 only for the installation step ("make install"). So make sure the
5746 user is aware of this fact but let him proceed as long as he can.
5747 [Ralf S. Engelschall] PR#2288
5749 *) Renamed three more functions to common ap_ prefix which we missed at the
5750 Big Symbol Renaming because they're #defines and not real C functions:
5751 is_default_port(), default_port(), http_method().
5752 [Ralf S. Engelschall]
5754 *) A zero-length name after a $ in an SSI document should cause
5755 just the $ to be in the expansion. This was broken during the

5765 Changes with Apache 1.3b7
5767 *) Make sure a MIME-type can be forced via a RewriteRule even when no
5768 substitution takes place, for instance via the following rule:
5769 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
5770 requested by users in the past to force a single script without a .cgi
5771 extension and outside any cgi-bin dirs to be executed as a CGI program.

5779 *) Fix discrepancy in proxy_ftp.c which was causing failures when
5780 trying to connect to certain ftpd's, such as anonftpd.
5781 [Rick Ohnemus <rick@ecompcon.com>]
5783 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
5784 logfile instead of fiddling around itself with child spawning stuff.
5785 [Ralf S. Engelschall]
5787 *) Made RefererIgnore case-insensitive.
5789 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
5792 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
5793 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
5796 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]

5799 of passwords, especially passwords with "0" chars.

5802 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5803 [Ben Laurie] PR#2238
5805 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5806 library), so CGI handling has been changed to use Win32 native handles
5807 instead of C file descriptors.
5808 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5810 *) The proxy cache would store an incorrect content-length in the cached
5811 file copy after a cache update. That resulted in repeated fetching
5812 of the original copy instead of using the cached copy.
5813 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5815 *) The Makefiles assumed that DSO files are build via $(LD). This
5816 is broken for two reasons: First we never defined at least LD=ld
5817 somewhere to make sure this works (it was silently assumed that most Make
5818 provide a built-in LD definition - ARGL!) and second using the generic LD
5819 variable is not the truth. Instead a special variable named LD_SHLIB is
5820 reasonable because although "ld" is usually the default, the command for
5821 building DSO files can be "libtool" or even "cc" on some systems.
5822 [Ralf S. Engelschall]
5824 *) Replace the AddVersionPlatform directive with ServerTokens which
5825 provides for more control over the format of the Server:
5826 header line. SERVER_SUBVERSION is no longer supported;
5827 all module should use the ap_add_version_component()
5828 API function instead. [Jim Jagielski]
5830 *) Support for the NCR MP/RAS 3.0
5831 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5833 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5834 not retrieved in src/Configure and thus was not useable.
5835 [Ralf S. Engelschall]
5837 *) Various Makefile consistency cleanups:
5838 - make OSDIR also automatically be relative to src/ like INCDIR
5839 - SUBDIRS is now generated in src/Makefile only and not in
5840 Makefile.config because it is a local define for this location.
5841 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5842 any Makefile but make sure that at least the "-K inline" is kept in
5844 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5845 - updated the dependencies theirself
5846 - removed not existing SHLIB variable from "clean" targets
5847 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5848 already exists and OBJS_PIC are also just plain objects and have not
5849 directly to do with "shared" things. The only difference is that they
5850 contain PIC. So OBJS_PIC is the more canonical name.
5851 - Updated the Makefile-dependency lines for OBJS_PIC
5852 - Removed the Makefile-dependency line in Configure to avoid double
5854 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5855 of xxx.lo as GNU libtool does with its PIC objects
5856 - reduce local complexity in modules Makefile.tmpl by moving the last
5857 existing target "depend" to the generation section in Configure, too.
5858 - removed the historical $(SPACER) which was used in the past together
5859 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5860 is no longer needed.
5861 - force the build and run of the gen_xxx programs under main/ as the
5862 first step before building the objects because it looks cleaner
5863 [Ralf S. Engelschall]
5865 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5868 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5871 *) WIN32: Don't force ISAPI headers to finish with \n.
5872 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5874 *) When opening "configuration" files (like httpd.conf, htaccess
5875 and htpasswd), Apache will not allow them to be non-/dev/null
5876 device files. This closes a DoS hole. At the same time,
5877 we use ap_pfopen to open these files to handle timeouts.
5878 [Jim Jagielski, Martin Kraemer]
5880 *) Apache will now log the reason its httpd children exit if they exit
5881 due to an unexpected signal. (It requires a new porting define,
5882 SYS_SIGLIST, which if defined should point to a list of text
5883 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5885 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5886 like WIN32. Before, Win32 CGI's could have had sporadic failures
5887 if a chdir call from one thread was made between another chdir call
5888 and a spawn in another thread. So, for now don't chdir for CGI scripts
5889 in WIN32. The current CGI "spec" is unclear as to whether it's
5890 necessary. Long-term fix is to either serialize the chdir/spawn combo
5891 or use WIN32 native calls to spawn a process. This temp fix was
5892 necessary to remove this as a showstopper for 1.3's release.
5895 *) Cleanup the suEXEC support in APACI and make it more safe:
5896 1. Add big fat hint in INSTALL about risks and to read the
5897 htdocs/manual/suexec.html document before using the suexec-related
5899 2. Make sure the user has at least provided one --suexec-xxxx option
5900 (specifies suEXEC parameters) in addition to --enable-suexec option.
5901 If only --enable-suexec is given APACI stops with a hint to INSTALL
5902 and htdocs/manual/suexec.html documents.
5903 3. Provide two additional --suexec-xxxx options to make the suEXEC
5904 configuration complete (especially for package maintainers who else
5905 had to patch the source tree) by providing ways to configure minimal
5906 UID/GID and safe PATH, too.
5907 [Ralf S. Engelschall]
5909 *) Cleanup of the `configure --shadow' process:
5910 - make sure the configure script creates its temporary files in the
5911 shadow tree to avoid conflicts with parallel configure runs
5912 - removed unnecessary option "-r" from "rm" call for Makefiles
5913 - make sure the configure scripts creates the shadow-wrapper Makefile
5914 only when no shadow trees already exists
5915 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5916 when no more shadow trees exists
5917 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5918 as fast (in the past it needed 70sec, now it runs just 38sec)
5919 - make sure CVS does not complain about the created files
5920 Makefille.<gnutriple> and directories src.<gnutriple>
5921 [Ralf S. Engelschall]
5923 *) Added the ap_add_version_component() API routine and the
5924 AddVersionPlatform core directive. The first allows modules to
5925 declare themselves in the Server response header field value,
5926 augmenting the SERVER_SUBVERSION define in the Configuration file
5927 with run-time settings (more useful in a loadable-module environment).
5928 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5929 into the server version string. [Ken Coar] PR#2056
5931 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5934 *) Emit the "Accept-Range" header for the default handler.
5935 [Brian Behlendorf] PR#1464
5937 *) Add a note to httpd.conf-dist that apache will on some systems fail
5938 to start when the Group # is set to a negative or large positive value.
5941 *) Make sure the module execution order is correct even when some modules
5942 are loaded under runtime (`LoadModule') via the DSO mechanism:
5943 1. The list of loaded modules is now a dynamically allocated one
5944 and not the original statically list from modules.c
5945 2. The loaded modules are now correctly setup by LoadModule for
5946 later use by the AddModule command.
5947 3. When the DSO mechanism for modules is used APACI's `install'
5948 target now enables all created `LoadModule' lines per default because
5949 this is both already expected by the user _and_ needed to avoid
5950 confusion with the next point and reduces the Makefile.tmpl complexity
5951 4. When the DSO mechanism for modules is used, APACI's `install'
5952 target now additionally makes sure the module list is reconstructed
5953 via a complete `ClearModuleList+AddModule...' entry.
5954 5. The support tool `apxs' now also makes sure an AddModule command
5955 is added in addition to the LoadModule command.
5956 6. The modules.c generation was extended to now contain two
5957 comments to make sure no one is confused by the confusing terminology
5958 of loading/linking (we use load=link+load & link=activate instead of
5959 the obvious load=activate & link=link :-( )
5960 This way now there is no longer a difference under execution time between
5961 statically and dynamically linked modules.

5964 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5965 Big Symbol Renaming. [Ralf S. Engelschall]
5967 *) Add a comment to mod_example.c showing the format of a FLAG command
5970 *) Standardized the time format in mod_status to match that of other
5971 places in the code (e.g. DATE_GMT). PR#1551
5973 *) Fix handling of %Z in timefmt strings for those platforms with no time
5974 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5977 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5978 feature compatible with 'UseCanonicalName off' by changing
5979 r->server->server_hostname to ap_get_server_name(). And I changed some
5980 functions which use r->server->port to use ap_get_server_port() instead,
5981 because if there's no Port directive in the config r->server->port is 0.
5984 *) get/set_module_config are trivial enough to be better off inline. Worth
5985 1.5% performance boost. [Dean Gaudet]
5987 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5988 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5991 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5992 the task environment to the unprivileged User id. Otherwise CGI scripts
5993 would have a way to gain super user access. [Martin Kraemer]
5995 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5996 absolute path, only log base name of logging source as is done
5997 in unix. [Martin Kraemer]
5999 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
6000 the encoding type from the Accept-Encoding header (if it's there)
6001 and use it in the response, as that's probably what it'll be expecting.
6002 [Ronald.Tschalaer@psi.ch]
6004 *) Fix to mod_alias: translate_alias_redir is dealing with
6005 a URI, not a filename, so the check for drive letters for win32
6006 and emx is not necessary. [Dean Gaudet]
6008 *) WIN32: Allow .cmd as an executable extension.

6014 *) Child processes can now "signal" (by exiting with a status
6015 of APEXIT_CHILDFATAL) the parent process to abort and
6016 shutdown the server if the error in the child process was
6017 fatal enough. [Jim Jagielski]

6026 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
6028 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
6031 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6032 Additionally the checks for finding the vendor DSO library were moved
6033 from mod_so.c to Configure because first it needs $PLAT etc. and second
6034 mod_so already uses an abstraction layer and does not fiddle with the
6035 vendor functions itself.
6036 [Jens-Uwe Mager, Ralf S. Engelschall]
6038 *) PORT: Some optimization defines for NetBSD
6039 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6041 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6042 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6044 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6045 AIX variants should work fine, too. Even AIX 3.x should work). This is
6046 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6047 which we put into a os/unix/os-dso-aix.c file.
6048 [Ralf S. Engelschall]
6050 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6051 that we should use NET_SIZE_T == int but the include files force size_t.
6052 [Ralf S. Engelschall]
6054 *) Fix two bugs in select() handling in http_main.c.
6057 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6058 is unset (as it is in situations like timeouts) where it is unclear
6059 whether errno is set or not. [Martin Kraemer]
6061 *) Just having APACI's localstatedir is too general and not enough for most
6062 of the systems. 1.3b6 again required manual APACI patches by package
6063 maintainers from RedHat and FreeBSD because for their filesystem layout a
6064 little bit more flexibility in configuring the paths is needed. Hence we
6065 provide three additional configure options (--runtimedir, --logfiledir,
6066 --proxycachedir) which now can be used for more granular adjustments if
6067 --localstatedir is not enough to fit the particular needs. As a nice
6068 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6069 [Ralf S. Engelschall]
6071 *) Make the install root for "make install" in APACI's Makefile overrideable
6072 by package authors. This way we are even more friendly to package
6073 maintainers (especially Debian and RedHat) who build for the real prefix
6074 via "configure --prefix=/<real>" but use a different local prefix via
6075 "make root=/tmp/apache install" for rolling the package without bristling
6076 the target location on their system.
6077 [Ralf S. Engelschall]
6079 *) Workaround sed limitations in APACI's configure script by now
6080 substituting in chunks of 50 commands (because for instance HPUX's vendor
6081 sed has a limit of max. 98 commands)
6082 [Ralf S. Engelschall] PR#2136
6084 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
6085 [Ralf S. Engelschall] PR#2140
6087 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6088 RENAMING process because they are defined as pre-processor macros instead
6089 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6090 [Ralf S. Engelschall]
6092 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6093 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6094 [Ralf S. Engelschall] PR#2139
6096 *) Various bugfixes and cleanups for the APACI configure script:
6097 o fix IFS handling for _nested_ situation
6098 o fix Perl interpreter search: take first one found instead of last one
6099 o fix DSO consistency check
6100 o print error messages to stderr instead of stdout
6101 o add install-quiet for --shadow situation to Makefile stub
6102 o reduce complexity by avoiding sed-hacks for rule and module list loops
6103 [Ralf S. Engelschall]
6105 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6107 *) Make sure the input field separator (IFS) shell variable is explicitly
6108 initialized correctly before _every_ `for' loop and also restored after
6109 the loops. [Ralf S. Engelschall]
6111 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6112 `magic' files from an existing Apache installation. Because people often
6113 customize these for own MIME and content types.
6114 [Ralf S. Engelschall]

6117 [Peter Galbavy, Ralf S. Engelschall] PR#2109
6119 *) Fix the path to the ScoreBoardFile in the install-config target, too.
6120 [Ralf S. Engelschall] PR#2105
6122 *) Let "configure" clear out the users parameters (provided as shell
6123 variables) to avoid side-effects in "src/Configure" when the user
6124 exported them (which is not needed, but some users do it).
6125 [Ralf S. Engelschall] PR#2101
6127 *) Provide backward compatibility from some old src/Configuration.tmpl
6128 parameter names to the canonical Autoconf-style shell variable names. For
6129 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
6130 but a hint message is displayed. [Ralf S. Engelschall]

6151 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6153 *) If you start apache with the -S command line option it will dump
6154 out the parsed vhost settings. This is useful for folks trying
6155 to figure out what is wrong with their vhost configuration.
6156 (Other dumps may be added in the future.) [Dean Gaudet]
6158 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6159 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6162 *) Because /usr/local/apache is the default prefix the ``configure
6163 --compat'' option no longer has to set prefix, again. This way the
6164 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6166 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6167 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6168 to avoid "discard const" warnings. [Ralf S. Engelschall]
6170 *) If a specific handler is set for a file yet the request still
6171 ends up being handled by the default handler, log an error
6172 message before handling it. This catches things such as trying
6173 to use SSIs without mod_include enabled. [Marc Slemko]
6175 *) Fix error logging for the startup case where ap_log_error() still uses
6176 stderr as the target. Now the default log level is honored here, too.
6177 [Ralf S. Engelschall]
6179 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
6180 long" errors when generating the MODULES entry for src/Makefile
6181 [Ben Hyde, Ralf S. Engelschall]
6183 *) Make sure src/Configure doesn't complain about the old directory
6184 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6186 Changes with Apache 1.3b6
6188 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6190 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6191 interface via the similar but proprietary HP/UX shl_xxx-style system
6192 calls. [Ralf S. Engelschall]
6194 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6195 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6196 Make. [Ralf S. Engelschall]
6198 *) ++++ THE BIG SYMBOL RENAMING ++++
6199 To avoid symbol clashes with third-party code compiled into the server,
6200 we globally applied the prefix "ap_" to the following classes of
6202 - Apache provided general functions (e.g., ap_cpystrn)
6203 - Public API functions (e.g., palloc, bgets)
6204 - Private functions which we can't make static (because of
6205 cross-object usage) but should be (e.g., new_connection)
6206 For backward source compatibility a new header file named compat.h was
6207 created which provides defines for the old symbol names and can be used
6208 by third-party module authors.
6211 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6212 problem under SVR4 is that there is no command flag to force the linker
6213 to export the global symbols of the httpd executable therewith they are
6214 available to the DSO's. Instead of problematic hacks like creating a
6215 dummy.so file (containing dummy references to all global symbols) the
6216 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6217 Placing the Apache core code itself into a DSO library named libhttpd.so.
6218 This way the global symbols _HAVE_ to be exported and thus are available
6219 to any manually loaded DSO's under runtime. To reduce the impact to the
6220 user to null we go even further and create a stub httpd executable which
6221 automatically keeps track of the DSO library loading itself and thus
6222 hides the complete mechanism from the user. Although the generation of
6223 this DSO library is automatically triggered for platforms which
6224 essentially need it (mostly all SVR4-derivates) it can be also enabled
6225 manually via the Rule SHARED_CORE. This can be interesting in the future
6226 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6227 features like graceful upgrades, or whatever.
6228 [Ralf S. Engelschall, Martin Kraemer]
6230 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6232 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6233 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6234 conventions while "clean" removes only stuff created by "all" targets,
6235 "distclean" additionally removes the stuff from the configuration
6236 process. This way "make distclean" (hence the name) provides a fresh
6237 source tree as it was for distribution.
6238 [Ralf S. Engelschall]
6240 *) Allow top-level (APACI) Makefile to break on build errors
6241 the same way the src/ subtree Makefiles breaks on them by replacing the
6242 initial APACI sed-subdir-display-kludge with a more clean
6243 variable-passing-solution: variable SDP can optionally hold the subdir
6244 prefix which is consistently used for displaying the subdir movement.
6245 This way even the top-level Makefile can stop correctly on errors as the
6246 user expects. [Ralf S. Engelschall]
6248 *) Fixed ordering of argument checks for RewriteBase directive.
6249 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6251 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6252 indicating that a module is being compiled for dynamic loading. Also
6253 remove #define IS_MODULE from modules and add SHARED_MODULE define
6254 to the mak/dsp files. [Alexei Kosut]
6256 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6257 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6259 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6261 *) Add documentation file and src/Configuration.tmpl entry for the
6262 experimental mod_mmap_static module. Because although it is and marked as
6263 an experimental one it is distributed and thus should be documented and
6264 prepared for configuration the same way as all others modules.
6265 [Ralf S. Engelschall]
6267 *) Add query (-q) option to apxs support tool to be able to manually query
6268 specific settings from apxs. This is needed for instance when you
6269 manually want to access Apache's header files and you need to assemble
6270 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6271 [Ralf S. Engelschall]
6273 *) Now src/Configure uses a fallback strategy for the shared object support
6274 on platforms where no explicit information is available: If a Perl
6275 installation exists we ask it about its shared object support and if it's
6276 the dlopen-style one we shamelessly guess the compiler and linker flags
6277 for creating shared objects from Perls knowledge. Of course, the user is
6278 warning about what we are doing and informed that he should send us
6279 the guessed flags when they work. [Ralf S. Engelschall]
6281 *) Provide APACI --without-support option to be able to disable the build
6282 and installation of the support tools from the src/support/ area.
6283 Although its useful to have these installed per default we should provide
6284 a way to compile and install without them for backward-compatibility.
6285 [Ralf S. Engelschall]
6287 *) Add of the new APache eXtenSion (apxs) support tool for building and
6288 installing modules into an _already installed_ Apache package through the
6289 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6290 this approach actually doesn't need the Apache source tree. The
6291 (APACI-installed) server package is enough, because this now includes the
6292 Apache C header files (PREFIX/include) and the new APXS tool
6293 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6294 module authors to build their Apache modules _OUTSIDE_ the Apache source
6295 tree while avoiding them to fiddle around with the totally platform
6296 dependend way of compiling DSO files. The tool supports all ranges of
6297 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6298 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6299 on-the-fly generate a minimalistic Makefile and sample module for the
6300 first step to provide both a quick success event and to demonstrate the
6301 APXS mechanism to module authors. [Ralf S. Engelschall]
6303 *) Fix core dumps in use of CONNECT in proxy.
6304 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6306 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6307 so that users have examples of how CustomLog can be used.
6310 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6311 the Apache distribution tree. Until Apache 1.3 there was no real
6312 out-of-the-box batch-capable build and installation procedure for the
6313 complete Apache package. This is now provided by a top-level "configure"
6314 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6315 to provide a GNU Autoconf-style frontend which is capable to both drive
6316 the old src/Configure stuff in batch and additionally installs the
6317 package with a GNU-conforming directory layout. Any options from the old
6318 configuration scheme are available plus a lot of new options for flexibly
6319 customizing Apache. [Ralf S. Engelschall]
6321 *) The floating point ap_snprintf code wasn't threadsafe.
6322 Had to remove the HAVE_CVT macro in order to do threadsafe
6323 calling of the ?cvt() floating point routines. [Dean Gaudet]
6325 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6327 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
6328 [Jim Jagielski] PR#1901
6330 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6331 Configure knows which CC we are using. [Jim Jagielski]
6333 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6334 was defined in a parent directory. [Lars Eilebrecht]
6336 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6337 a generic printf-style routine that can call arbitrary output
6338 routines. Use this to replace http_bprintf.c. Add new routines
6339 psprintf(), pvsprintf() which allocate the exact amount of memory
6340 required for a string from a pool. Use psprintf() to clean up
6341 various bits of code which used ap_snprintf()/pstrdup().
6344 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6345 ap_snprintf() has different semantics and formatting codes than
6346 snprintf(). [Dean Gaudet]
6348 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6349 is necessary on at least Solaris where the /etc/rc?.d scripts
6350 are run with these signals ignored, and "SIG_IGN" settings are
6351 maintained across exec().

6376 properly marked for closure on fork().
6377 [Jürgen Keil <jk@tools.de>] PR#2000
6379 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6380 therefore not exposed to %2F -> '/' translations and 2) the request
6381 is a proxy request, so we're not dealing with a local resource anyway.
6382 Without this, the proxy would fail to work for any URL's with
6383 %2f in them (occurs quite often in
6384 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6386 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6388 *) Make the shared object compilation command more portable by avoiding
6389 the direct combination of `-c' & `-o' which is not honored by some
6390 compilers like UnixWare's cc. [Ralf S. Engelschall]
6392 *) WIN32: the proxy was creating filenames missing the last four

6401 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6402 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6403 name was really too generic, added documentation for this directive to
6404 the mod_proxy.html and corrected the hyperlink to it in the

6410 *) Make Configure die when you give it an unknown command switch.
6413 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6414 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6415 and per default compiled support programs have manual pages - just to
6416 document our stuff a little bit more and to be able to do really
6417 Unix-like installations ;-) [Ralf S. Engelschall]
6419 *) Major cleanups to the Configure script to make it and its generated
6420 Makefiles again readable and maintainable: add SRCDIR option, removed
6421 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6422 generated sections, consequently added Makefile headers with inheritance
6423 information, added subdir movement messages for easier following where
6424 the build process currently stays (more verbose then standard Make, less
6425 verbose than GNU make), same style to comments in the Configure script,
6426 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6428 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6429 from the ZeusBench benchmarking program and can be used to determine the

6433 [Ralf S. Engelschall]
6435 *) API: Various core functions that are definately not part of the API
6436 have been made static, and a few have been marked API_EXPORT. Still
6437 more have been marked CORE_EXPORT and are not intended for general
6438 use by modules. [Doug MacEachern, Dean Gaudet]
6440 *) mod_proxy was not clearing the Proxy-Connection header from
6441 requests; now it does. This did not violate any spec, however
6442 causes poor interactions when you are talking to remote proxies.
6443 [Marc Slemko] PR#1741
6445 *) Various cleanups to the command line interface and manual pages.
6446 [Ralf S. Engelschall]
6448 *) cfg_getline() was not properly handling lines that did not end
6449 with a line termination character. [Marc Slemko] PR#1869, 1909
6451 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6453 *) Clean up some undocumented behavior of mod_setenvif related to
6454 "merging" two SetEnvIf directives when they match the same header
6455 and regex. Document that mod_setenvif will perform comparisons in
6456 the order they appear in the config file. Optimize mod_setenvif by
6457 doing more work at config time rather than at runtime.
6460 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6461 to allow for modules to overrule them and to reduce redefinition
6462 warnings [Jim Jagielski]
6464 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6467 *) Making the hard-coded cross-module function call mime_find_ct() (from
6468 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6469 checking is really called even for proxy requests except for URLs with
6470 HTTP schemes (because there we can optimize by not running the type
6471 checking hooks due to the fact that the proxy gets the MIME Content-type
6472 from the remote host later). This change cleans up mod_mime by removing
6473 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6474 especially unbundles mod_proxy and mod_mime. This way they both now can
6475 be compiled as shared objects and are no longer tied together.
6476 [Ralf S. Engelschall]
6478 *) util.c cleanup and speedup. [Dean Gaudet]
6480 *) API: Clarification, pstrndup() will always copy n bytes of the source
6481 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6483 *) Mark module command_rec and handler_rec structures const so that they
6484 end up in the read-only data section (and are friendlier to systems
6485 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6487 *) Add check to the "Port" directive to make sure the specified
6488 port is in the appropriate range. [Ben Hyde]
6490 *) Performance improvements to invoke_handler().
6491 [Dmitry Khrustalev <dima@bog.msu.su>]
6493 *) Added support for building shared objects even for library-style modules
6494 (which are built from more than one object file). This now provides the
6495 ability to build mod_proxy as a shared object module. Additionally
6496 modules like mod_example are now also supported for shared object
6497 building because the generated Makefiles now no longer assume there is at
6498 least one statically linked module. [Ralf S. Engelschall]
6500 *) API: Clarify usage of content_type, handler, content_encoding,
6501 content_language and content_languages fields in request_rec. They
6502 must always be lowercased; and the strings pointed to shouldn't
6503 be modified (you must copy them to modify them). Fix a few bugs
6504 related to this. [Dean Gaudet]
6506 *) API: Clarification: except for RAW_ARGS, all command handlers can
6507 treat the char * parameters as permanent, and modifiable. There
6508 is no need to pstrdup() them. Clean up some needless pstrdup().
6511 *) Now mod_so keeps track of which module shared objects with which names
6512 are loaded and thus avoids multiple loading and unloading and irritating
6513 error_log messages. [Ralf S. Engelschall]
6515 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6516 environment variable in the apache core. But that tweaking interferes
6517 with mod_setenv. So don't tweak if the user has specified an explicit
6518 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6520 *) rputs() did not calculate r->sent_bodyct properly.
6521 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6523 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6524 name, or left unset if this value is unavailable. Apache was setting
6525 it to the IP address when unavailable.
6526 [Tony Finch <fanf@demon.net>] PR#1925
6528 *) Various improvements to the configuration and build support for compiling
6529 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6530 OSF1 support with GCC and vendor compilers was added. This way shared
6531 object support is now provided out-of-the-box for FreeBSD, Linux,
6532 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6533 [Ralf S. Engelschall]
6535 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6536 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6537 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6539 *) Fix one more special locking problem for RewriteMap programs in
6540 mod_rewrite: According to the documentation of flock(), "Locks are on
6541 files, not file descriptors. That is, file descriptors duplicated
6542 through dup(2) or fork(2) do not result in multiple instances of a lock,
6543 but rather multiple references to a single lock. If a process holding a
6544 lock on a file forks and the child explicitly unlocks the file, the
6545 parent will lose its lock.". To overcome this we have to make sure the
6546 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6547 the case by opening it in the child_init instead of the module_init API
6548 hook. [Ralf S. Engelschall] PR#1029
6550 *) Change to Location and LocationMatch semantics. LocationMatch no
6551 longer lets a single slash match multiple adjacent slashes in the
6552 URL. This change is for consistency with RewriteRule and
6553 AliasMatch. Multiple slashes have meaning in URLs that they do
6554 not have in (some) filesystems. Location on the other hand can
6555 be considered a shorthand for a more complicated regex, and it
6556 does match multiple slashes with a single slash -- which is
6557 also consistent with the Alias directive.
6558 [Dean Gaudet] related PR#1440
6560 *) Fix bug with mod_mime_magic causing certain files, including files
6561 of length 0, to result in no response from the server.
6564 *) The Configure script now generates src/include/ap_config.h which
6565 contains the set of defines used when Apache is compiled on a platform.
6566 This file can then be included by external modules before including
6567 any Apache header files in case they are being built separately from
6568 Apache. Along with this change, a couple of minor changes were
6569 made to make Apache's #defines coexist peacefully with any autoconf
6570 defines an external module might have. [Rasmus Lerdorf]
6572 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6573 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6574 chance by the API to initialize its per-server configuration and thus
6575 receives the wrong one from the main server. This is now avoided by
6576 remembering the server together with the config structure while
6577 configuring and later assuming there is no config when we see a
6578 difference between the remembered server and the one calling us.
6579 [Ralf S. Engelschall] PR#1790
6581 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6582 is automatically disabled under configure time when the dbm_xxx functions
6583 are not available. Second, two heavy source code errors in the DBM
6584 support code were fixed. This makes DBM RewriteMap's usable again after
6585 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6587 *) Now all configuration files support Unix-style line-continuation via
6588 the trailing backslash ("\") character. This enables us to write down
6589 complex or just very long directives in a more readable way. The
6590 backslash character has to be really the last character before the
6591 newline and it has not been prefixed by another (escaping) backslash.
6592 [Ralf S. Engelschall]
6594 *) When using ProxyPass the ?querystring was not passed correctly.
6595 [Joel Truher <truher@wired.com>]
6597 *) To deal with modules being compiled and [dynamically] linked
6598 at a different time from the core, the SERVER_VERSION and
6599 SERVER_BUILT symbols have been abstracted through the new
6600 API routines apapi_get_server_version() and apapi_get_server_built().
6603 *) WIN32: Preserve trailing slash in canonical path (and hence
6604 in PATH_INFO). [Paul Sutton, Ben Laurie]
6606 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6607 depending on the rev of Solaris and what mixture of modules
6608 are in use. So it has been disabled, and Solaris is back to
6609 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6610 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6611 up static content only servers. Or it may fail unpredictably.
6612 [Dean Gaudet] PR#1779, 1854, 1904
6614 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6617 *) API: Rewrite of absoluteURI handling, and in particular how
6618 absoluteURIs match vhosts. Unless a request is a proxy request, a
6619 "http://host" url is treated as if a similar "Host:" header had been
6620 supplied. This change was made to support future HTTP/1.x protocols
6621 which may require clients to send absoluteURIs for all requests.
6623 In order to achieve this change subtle changes were made to the API. In a
6624 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6625 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6626 by the core, modules must set it during the post_read_request or
6627 translate_names phase.
6629 Plus changes to the virtualhost test suite for absoluteURI testing.
6631 This fixes several bugs with the proxy proxying requests to vhosts
6632 managed by the same httpd.
6635 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6636 code from mod_rewrite. The vhost matching is now performed by a
6637 globally available function matches_request_vhost(). [Dean Gaudet]
6639 *) Reduce memory usage, and speed up ServerAlias support. As a
6640 side-effect users can list multiple ServerAlias directives
6641 and they're all considered.
6642 [Chia-liang Kao <clkao@cirx.org>] PR#1531
6644 *) The "poly" directive in image maps did not include the borders of the
6645 polygon, whereas the "rect" directive does. Fix this inconsistency.
6646 [Konstantin Morshnev <moko@design.ru>] PR#1771
6648 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
6650 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
6651 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
6653 *) API: A new source module main/util_uri.c; It contains a routine
6654 parse_uri_components() and friends which breaks a URI into its component
6655 parts. These parts are stored in a uri_components structure called
6656 parsed_uri within each request_rec, and are available to all modules.
6657 Additionally, an unparse routine is supplied which re-assembles the URI
6658 components back to an URI, optionally hiding the username:password@ part
6659 from ftp proxy requests, and other useful routines. Within the structure,
6660 you find on a ready-for-use basis:
6661 scheme; /* scheme ("http"/"ftp"/...) */
6662 hostinfo; /* combined [user[:password]@]host[:port] */
6663 user; /* user name, as in http://user:passwd@host:port/ */
6664 password; /* password, as in http://user:passwd@host:port/ */
6665 hostname; /* hostname from URI (or from Host: header) */
6666 port_str; /* port string (integer representation is in "port") */
6667 path; /* the request path (or "/" if only scheme://host was given) */
6668 query; /* Everything after a '?' in the path, if present */
6669 fragment; /* Trailing "#fragment" string, if present */
6670 This is meant to serve as the platform for *BIG* savings in
6671 code complexity for the proxy module (and maybe the vhost logic).
6674 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6675 ${map:key}) available for all location where a string is created in
6676 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6677 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6678 possible expansions are consequently usable at all string creation
6679 locations. [Ralf S. Engelschall]
6681 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6682 and not 1) and the per-virtual-server merging of directives. Now all
6683 directives except `RewriteEngine' and `RewriteOption' are either
6684 completely overridden (default) or completely inherited (when
6685 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
6687 *) Fix `RewriteMap' program lookup in situations where such maps are
6688 defined but disabled (`RewriteEngine off') in per-server context.
6689 [Ralf S. Engelschall] PR#1431
6691 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6692 server to bind to port 0 rather than 80. [Dean Gaudet]
6694 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6695 (like SunOS and FreeBSD) which don't accept the locking of pipes
6696 directly. A new directive RewriteLock is introduced which can be used to
6697 setup a separate locking file which then is used for synchronization.
6698 [Ralf S. Engelschall] PR#1029
6700 *) WIN32: The server root is obtained from the registry key
6701 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
6702 "1.3 beta"), unless overridden by the -d command line flag. The
6703 value is stored by running "apache -i -d serverroot". [Paul Sutton]
6705 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
6706 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]
6708 *) Now mod_rewrite no longer makes problematic assumptions on the characters
6709 a username can contain when trying to expand it via /etc/passwd.
6710 [Ralf S. Engelschall]
6712 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6713 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6715 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6716 type but with a special post-processing for the looked-up value: It
6717 parses it into alternatives according to `|' chars and then only one
6718 particular alternative is chosen randomly (this is an essential
6719 functionality needed for balancing between backend-servers when using
6720 Apache as a Reverse Proxy. The looked up value here is a list of
6721 servers). Second, `int' with the built-in maps named `tolower' and
6722 `toupper' which can be used to map URL parts to a fixed case (this is an
6723 essential feature to fix the case of server names when doing mass
6724 virtual-hosting with the help of mod_rewrite instead of using
6725 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6726 Jay Soffian <jay@cimedia.com>] PR#1631
6728 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6729 This directive lets Apache adjust the URL in Location-headers on HTTP
6730 redirect responses sent by the remote server. This way the virtually
6731 mapped area is no longer left on redirects and thus by-passed which is
6732 especially essential when running Apache as a reverse proxy.
6733 [Ralf S. Engelschall]
6735 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
6736 hidden. [Alvaro Martinez Echevarria]
6738 *) Apache will, when started with the -X (single process) debugging flag,
6739 honor the SIGINT or SIGQUIT signals again now. This capability got lost
6740 a while ago during OS/2 signal handling changes.
6742 *) [PORT] Work around the fact that NeXT runs on more than the
6743 m68k chips in mod_status [Scott Anguish and Timothy Luoma

6750 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
6751 In particular the handlers could trigger themselves into an infinite
6752 loop if RLimitMem was used with a small amount of memory -- too small
6753 for the signal stack frame to be set up. [Dean Gaudet]

6767 *) mod_info would occasionally produce an unpaired <tt> in its
6768 output. Fixed. [Martin Kraemer]
6770 *) By default AIX binds a process (and it's children) to a single
6771 processor. httpd children now unbind themselves from that cpu
6772 and re-bind to one selected at random via bindprocessor()
6775 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
6776 effect. Work around it by using RLIMIT_AS for the RLimitMEM
6777 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816

6843 *) MiNT port update. [Jan Paul Schmidt]
6845 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
6846 equivalent, similarly for x-compress and compress. Apache
6847 now ignores a leading x- when comparing encodings. It also
6848 preserves the encoding the client requests (for example if
6849 it requests x-gzip, then Apache will respond with x-gzip
6850 in the Content-Encoding header).

6853 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]

6858 [Sameer Parekh, Paul Sutton]
6860 *) Minor cleanups to r->finfo handling in some modules.

6864 Makes it easier to add other types of IO code such as SFIO.
6867 *) API: Generalize default_port manipulations to make support of
6868 different protocols easier. [Ben Laurie, Randy Terbush]
6870 *) There are many cases where users do not want Apache to form
6871 self-referential urls using the "canonical" ServerName and Port.
6872 The new UseCanonicalName directive (default on), if set to off

6878 PR#315, 459, 485, 1433
6880 *) Yet another rearrangement of the source tree.. now all the common
6881 header files are in the src/include directory. The -Imain -Iap
6882 references in Makefiles have been changed to the simpler -Iinclude
6883 instead. In addition to simplifying the build a little bit, this
6884 also makes it clear when a module is referencing something in a
6885 other than kosher manner (e.g., the proxy including mod_mime.h).
6886 Module-private header files (the proxy, mod_mime, the regex library,
6887 and mod_rewrite) have not been moved to src/include; nor have
6888 the OS-abstraction files. [Ken Coar]
6890 *) Fix a bug where r->hostname didn't have the :port stripped
6891 from it. [Dean Gaudet]
6893 *) Tweaked the headers_out table size, and the subprocess_env

6895 MAKE_TABLE_PROFILE which can help discover make_table()
6896 calls that use too small an initial guess, see alloc.c.
6899 *) Options and AllowOverride weren't properly merging in the main
6900 server setting inside vhosts (only an issue when you have no
6901 <Directory> or other section containing an Options that affects
6902 a request). Options +foo or -foo in the main_server wouldn't

6915 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6917 *) mod_unique_id was erroneously generating a second unique id when
6918 an internal redirect occured. Such redirects occur, for example,
6919 when processing a DirectoryIndex match. [Dean Gaudet]
6921 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6922 of the key and value. But in many cases this is not required
6923 because the key/value is a constant, or the value has been built
6924 by pstrcat() or other similar means. New routines table_addn,
6925 table_mergen, and table_setn have been added to the API, these
6926 routines do not pstrdup() their arguments. The core code and
6927 standard modules were changed to take advantage of these routines.
6928 The resulting server is up to 20% faster in some situations.
6930 Note that it is easy to get code subtly wrong if you pass a key/value
6931 which is in a pool other than the pool of the table. The only
6932 safe thing to do is to pass key/values which are in the pool of
6933 the table, or in one of the ancestors of the pool of the table.
6934 i.e. if the table is part of a subrequest, a value from the main
6935 request's pool is OK since the subrequest pool is a sub_pool of the
6936 main request's pool (and therefore has a lifespan at most as long as
6937 the main pool). There is debugging code which can detect improper
6938 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6939 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6941 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6942 which don't exist on disk more gracefully; handles vhosts properly.
6943 Update documentation to reflect the code -- if there's no
6944 MimeMagicFile directive then the module is not enabled.
6947 *) PORT: Some older *nix dialects cannot automatically start scripts
6948 which begin with a #! interpreter line (the shell starts the scripts
6949 appropriately on these platforms). Apache now supports starting of
6950 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6951 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6954 *) API: "typedef array_header table" removed from alloc.h, folks should
6955 have been writing to use table as if it were an opaque type, but even
6956 some standard modules got this wrong. By changing the definition
6957 to "typedef struct table table" module authors will receive compile
6958 time warnings that they're doing the wrong thing. This change
6959 facilitates future changes with more sophisticated table
6960 structures. Specifically, module authors should be using table_elts()
6961 to get access to an array_header * for the table. [Dean Gaudet]
6963 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6964 library routines. [Ken Coar, Rasmus Lerdorf]
6966 *) WIN32: mod_speling is now available on the Win32 platform.
6969 *) For clarity the following compile time definition was changed:
6971 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6973 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6974 and not be a general notice that the OS has mmap(). Now the
6975 HAVE_MMAP/SHMGET #defines strictly are informational that the
6976 OS has that method of shared memory; the type to use for
6977 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6978 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6979 determine if shared memory is available and allows Apache
6980 to determine the best method to use for the scoreboard.
6983 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6984 as do various earlier versions. It should be safe on all versions.

6986 the slack code. A few other cleanups for Unixware.

7009 The choice of flock vs. fcntl was made based on timings which showed that
7010 even on non-NFS, non-exported filesystems fcntl() was an order of
7011 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
7012 that single socket users will see no difference. [Dean Gaudet] PR#467

7072 *) For maximum portability, the environment passed to CGIs should
7073 only contain variables whose names match the regex

7075 underscores over any character outside the regex. This
7076 affects HTTP_* variables, in a way that should be backward

7321 is the same for both per-server and per-directory context with only a
7322 minimum difference (the prefix stripping in per-dir context). As a
7323 side-effect some subtle restrictions and two recently discovered problems

7459 *) PORT: Basic Gemini port (treat it like unixware212).
7460 ["Pavel Yakovlev (Paul McHacker)" <hac@tomcat.olly.ru>]
7462 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
7463 use USE_SHMGET_SCOREBOARD.
7466 *) Various improvements in detecting config file errors (missing closing
7467 directives for <Directory>, <Files> etc. blocks, prohibiting global
7468 server settings in <VirtualHost> blocks, flagging unhandled multiple
7469 arguments to <Directory>, <Files> etc.)
7472 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
7473 variable to provide this one to suexec'd CGIs, too.
7474 [M.D.Parker <mdpc@netcom.com>] PR#1284
7476 *) New support tool: src/support/split-logfile, a sample Perl script which
7477 splits up a combined access log into separate files based on the
7478 name of the virtual host (listed first in the log records by "%v").
7481 Changes with Apache 1.3b2 (there is no 1.3b1)
7483 *) TestCompile was not passing $LIBS [Dean Gaudet]
7485 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7488 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7489 rudimentary memory debugger which can be used on live servers with
7490 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7491 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7492 and free() for each object. This is far more expensive and should
7493 only be used for testing with tools such as Electric Fence and
7494 Purify. See main/alloc.c for more details. [Dean Gaudet]
7496 *) Configure uses a sh trap and didn't set its exitcode properly.
7497 [Dean Gaudet] PR#1159
7499 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7500 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7501 From a given ip:port, regardless what the Host: header is, you can
7502 only reach the vhosts defined on that ip:port. The precedence of
7503 vhosts was reversed to match other precedences in the config --
7504 the earlier vhosts override the later vhosts. All vhost matching was
7505 moved into http_vhost.[ch]. [Dean Gaudet]
7507 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7508 be used for whatever reason is appropriate (i.e. format() warnings
7509 for printf style functions). Both are enabled only with
7510 gcc >= 2.7.x (so that we have fewer support issues with older
7511 versions). [Dean Gaudet]
7513 *) Fix support for Proxy Authentication (we were testing the response
7514 status too early). [Marc Slemko]
7516 *) CoreDumpDirectory directive directs where the core file is
7517 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7518 received. [Marc Slemko, Dean Gaudet]
7520 *) PORT: Support for Atari MINT.
7521 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7523 *) When booting, apache will now detach itself from stdin, stdout,
7524 and stderr. stderr will not be detached until after the config
7525 files have been read so you will be able to see initial error
7526 messages. After that all errors are logged in the error_log.
7527 This makes it more convenient to start apache via rsh, ssh,
7528 or crontabs. [Dean Gaudet] PR#523
7530 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7531 Also removed the auto-generated link to www.apache.org that was the
7532 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7534 *) send_fb would not detect aborted connections in some situations.
7537 *) mod_include would use uninitialized data when parsing certain
7538 expressions involving && and ||. [Brian Slesinsky] PR#1139
7540 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7542 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7544 *) mod_autoindex improperly counted &escapes; as more than one
7545 character in the description. It also improperly truncated
7546 descriptions that were exactly the maximum length.
7549 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7550 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7553 *) mod_include now uses symbolic names to check for request success
7554 and return HTTP errors, and correctly handles all types of
7555 redirections (previously it only did temporary redirect correctly).
7556 [Ken Coar, Roy Fielding]
7558 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7559 r->filename. Since those two are meant to be in sync with each other
7560 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7562 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7563 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7565 *) Inetd mode (which is buggy) uses timeouts without having setup the
7566 jmpbuffer. [Dean Gaudet] PR#1064
7568 *) Work around problem under Linux where a child will start looping
7569 reporting a select error over and over.
7570 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7572 *) Fixed error in proxy_util.c when looping through multiple host IP
7573 addresses. [Lars Eilebrecht] PR#974
7575 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7576 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7577 bytes before writing, but it will never split a log entry across a
7578 buffer boundary. [Dean Gaudet]
7580 *) API: the short_score record has been split into two pieces, one which
7581 the parent writes on, and one which the child writes on. As part of
7582 this change the get_scoreboard_info() function was removed, and
7583 scoreboard_image was exported. This change fixes a race condition
7584 in file based scoreboard systems, and speeds up changes involving the
7585 scoreboard in earlier 1.3 development. [Dean Gaudet]
7587 *) API: New register_other_child() API (see http_main.h) which allows
7588 modules to register children with the parent for maintenance. It
7589 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7591 *) API: New piped_log API (see http_log.h) which implements piped logs,
7592 and will use register_other_child to implement reliable piped logs
7593 when it is available. The reliable piped logs part can be disabled
7594 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7595 logs is only available on Unix. [Dean Gaudet]
7597 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7598 meets_conditions(). This allows conditional HTTP selection to be
7599 handled separately from the storing of the header fields, and provides
7600 the ability for CGIs to set their own ETags for conditional checking.
7601 [Ken Coar, Roy Fielding] PR#895
7603 *) Changes to mod_log_config to allow naming of format strings.
7604 Format nicknames are defined with "LogFormat fmt nickname", and can
7605 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7608 *) New module, "mod_speling", which can help find files even when
7609 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7611 *) API: New function child_terminate() triggers the child process to
7612 exit, while allowing the child finish what it needs to for the
7613 current request first.
7614 [Doug MacEachern, Alexei Kosut]
7616 *) Windows now defaults to using full status reports with mod_status.
7617 [Alexei Kosut] PR #1094
7619 *) *Really* disable all mod_rewrite operations if the engine is off.
7620 Some things (like RewriteMaps) were checked/performed even if they
7621 weren't supposed to be. [Ken Coar] PR #991
7623 *) Implement a new timer scheme which eliminates the need to call alarm() all
7624 the time. Instead a counter in the scoreboard for each child is used to
7625 show when the child has made forward progress. The parent samples this
7626 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7627 progress has been made in the timeout period. This reduces the static
7628 request best-case syscall count to 22 from 29. This scheme is only
7629 used by systems with memory-based scoreboards. [Dean Gaudet]
7631 *) The proxy now properly handles CONNECT requests which are sent
7632 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7634 *) A script called apachectl has been added to the support
7635 directory. This script allows you to do things such as
7636 "apachectl start" and "apachectl restart" from the command
7639 *) Modules and core routines are now put into libraries, which
7640 simplifies the link line tremendously (among other advantages).
7643 *) Some of the MD5 names defined in Apache have been renamed to have
7644 an `ap_' prefix to avoid conflicts with routines supplied by
7645 external libraries. [Ken Coar]
7647 *) Removal of mod_auth_msql.c from the distribution. There are many
7648 other options for databases today. Rather than offer one option,
7649 offer none at this time. mod_auth_msql and other SQL database
7650 authentication modules can be found at the Apache Module Registry.
7651 http://modules.apache.org/ It would be nice to offer a generic
7652 mod_auth_sql option in the near future.
7654 *) PORT: BeOS support added [Alexei Kosut]
7656 *) Configure no longer accepts the -make option, since it creates
7657 Makefile on the fly based on Makefile.tmpl and Configuration.
7659 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7660 of forcibly killing off all its processes and exiting without
7661 cleaning up. [Alexei Kosut]
7663 *) API: A new field in the request_rec, r->mtime, has been added to
7664 avoid gratuitous parsing of date strings. It is intended to hold
7665 the last-modified date of the resource (if applicable). An
7666 update_mtime() routine has also been added to advance it if
7667 appropriate. [Roy Fielding, Ken Coar]
7669 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7670 deny access to the directory with a HTTP_FORBIDDEN. The previous
7671 behavior was to ignore the htaccess file if it could not be read.
7672 This change may make some setups with unreadable htaccess files
7673 stop working. [Marc Slemko] PR#817
7675 *) Add aplog_error() providing a mechanism to define levels of
7676 verbosity to the server error logging. This addition also provides
7677 the ability to log errors using syslogd. Error logging is configurable
7678 on a per-server basis using the LogLevel directive. Conversion
7679 of log_*() in progress. [Randy Terbush]
7681 *) Further enhance aplog_error() to not log filename, line number, and
7682 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7684 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7685 converted to long ones. Backslashes are converted to forward
7686 slashes. Case is converted to lower. Parts of URLs that do not
7687 correspond to files are left completely alone. [Ben Laurie]
7689 *) PORT: 2 new OSs added to the list of ports:
7690 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7691 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7693 *) Add the server version (SERVER_VERSION macro) to the "server
7694 configured and running" entry in the error_log. Also build an
7695 object file at link-time that contains the current time
7696 (SERVER_BUILT global const char[]), and include that in the
7699 *) Set r->headers_out when sending responses from the proxy.
7700 This fixes things such as the logging of headers sent from
7701 the proxy. [Marc Slemko] PR#659
7703 *) support/httpd_monitor is no longer distributed because the
7704 scoreboard should not be file based if at all possible. Use
7705 mod_status to see current server snapshot.
7707 *) (set_file_slot): New function, allowing auth directives to be
7708 independent of the server root, so the server documents can be
7709 moved to a different directory or machine more easily.
7710 [David J. MacKenzie]
7712 *) If no TransferLog is given explicitly, decline
7713 to log. This supports coexistence with other logging modules,
7714 such as the custom one that UUNET uses. [David J. MacKenzie]
7716 *) Check for titles in server-parsed HTML files.
7717 Ignore leading newlines and returns in titles. The old behavior
7718 of replacing a newline after <title> with a space causes the
7719 title to be misaligned in the listing. [David J. MacKenzie]
7721 *) Change mod_cern_meta to be configurable on a per-directory basis.
7722 [David J. MacKenzie]
7724 *) Add 'Include' directive to allow inclusion of configuration
7725 files within configuration files. [Randy Terbush]
7727 *) Proxy errors on connect() are logged to the error_log (nothing
7728 new); now they include the IP address and port that failed
7729 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7731 *) Various architectures now define USE_MMAP_FILES which causes
7732 the server to use mmap() for static files. There are two
7733 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7734 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7735 number of bytes written in one cycle from a single mmap()d object,
7736 default 32768). [Dean Gaudet]
7738 *) API: Added post_read_request API phase which is run right after reading
7739 the request from a client, or right after an internal redirect. It is
7740 useful for modules setting environment variables that depend only on
7741 the headers/contents of the request. It does not run during subrequests
7742 because subrequests inherit pretty much everything from the main
7743 request. [Dean Gaudet]
7745 *) Added mod_unique_id which is used to generate a unique identifier for
7746 each hit, available in the environment variable UNIQUE_ID.
7749 *) init_modules is now called after the error logs have been opened. This
7750 allows modules to emit information messages into the error logs.
7753 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7754 information for case where proxy module is not available. [Marc Slemko]
7756 *) PORT: Apache has need for mutexes to serialize its children around
7757 accept. In prior versions either fcntl file locking or flock file
7758 locking were used. The method is chosen by the definition of
7759 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7760 and FLOCK for flock(). New options have been added:
7761 - SYSVSEM to use System V style semaphores
7762 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7763 - USLOCK to use IRIX uslock
7764 Based on timing various techniques, the following changes were made
7766 - Linux 2.x uses flock instead of fcntl
7767 - Solaris 2.x uses pthreads
7768 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7769 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7770 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7771 Martijn Koster <m.koster@pobox.com>]
7773 *) PORT: The semantics of accept/select make it very desirable to use
7774 mutexes to serialize accept when multiple Listens are in use. But
7775 in the case where only a single socket is open it is sometimes
7776 redundant to serialize accept(). Not all unixes do a good job with
7777 potentially dozens of children blocked on accept() on the same
7778 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7779 the server will avoid serialization when listening on only one socket,
7780 and use serialization when listening on multiple sockets.
7781 [Dean Gaudet] PR#467
7783 *) Configure changes: TestLib replaced by TestCompile, which has
7784 some additional capability (such as doing a sanity check of
7785 the compiler and flags selected); the version of Solaris is now
7786 available via the #define value of SOLARIS2; IRIX n32bit libs
7787 now supported and selectable by new Configuration Rule: IRIXN32;
7788 We no longer default to -O2 optimization. [Jim Jagielski]
7790 *) Updated Configure: Configuration now uses AddModule to specify
7791 module source or binary file location, relative to src directory.
7792 Modules can be dropped into modules/extra, or in their own
7793 directory, and modules can come with a Makefile or Configure can
7794 create one. Modules can add compiler or library information to
7795 generated Makefiles. [Paul Sutton]
7797 *) Source core re-organisation: distributed modules are now in
7798 modules/standard. All other source code is in main. OS-specific
7799 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7801 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7804 *) Fix another long-standing bug in sub_req_lookup_file where it would
7805 happily skip past access checks on subdirectories looked up with
7806 relative paths. (It's used by mod_dir, mod_negotiation,
7807 and mod_include.) [Dean Gaudet]
7809 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7810 N is the number of <Directory> sections, and M is the number of
7811 components in the filename of an object.
7813 To achieve this optimization the following config changes were made:
7814 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7815 <Files>s, and <Location>s now treat a slash as a special
7816 character. For example "/home/*/public_html" previously would
7817 match "/home/a/andrew/public_html", now it only matches things
7818 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7819 - It's possible now to use [] wildcarding in <Directory>, <Files>
7821 - Regex <Directory>s are applied after all non-regex <Directory>s.
7825 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7826 and corrupted paths. [Dean Gaudet]
7828 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7829 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7830 be accessed now via backreferences $1..$9 in RewriteConds test-against
7831 strings in addition to RewriteRules subst string. Second the grouped
7832 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7833 via backreferences %1..%9 both in following RewriteCond test-against
7834 strings and RewriteRules subst string. This provides maximum flexibility
7835 through the use of backreferences.
7836 Additionally the rewriting engine was cleaned up by putting common
7837 code to the new expand_backrefs_inbuffer() function.
7838 [Ralf S. Engelschall]
7840 *) When merging the main server's <Directory> and <Location> sections into
7841 a vhost, put the main server's first and the vhost's second. Otherwise
7842 the vhost can't override the main server. [Dean Gaudet] PR#717
7844 *) The <Directory> code would merge and re-merge the same section after
7845 a match was found, possibly causing problems with some modules.
7848 *) ip-based vhosts are stored and queried using a hashing function, which
7849 has been shown to improve performance on servers with many ip-vhosts.
7850 Some other changes had to be made to accommodate this:
7851 - the * address for vhosts now behaves like _default_
7852 - the matching process now is:
7853 - match an ip-vhost directly via hash (possibly matches main
7855 - if that fails, just pretend it matched the main server
7856 - if so far only the main server has been matched, perform
7857 name-based lookups (ServerName, ServerAlias, ServerPath)
7858 *only on name-based vhosts*
7859 - if they fail, look for _default_ vhosts
7860 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7862 *) dbmmanage overhaul:
7863 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7864 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7865 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7866 - provide better seed for rand
7867 - prompt for password as per getpass(3) (turn off echo, read from
7869 - use "newstyle" crypt based on $Config{osname} ($^O)
7870 - will not add a user if already in database, use new `update' command
7872 - added `check' command to check a users' password
7873 - added `import' command to convert existing password text-files or
7874 dbm files exported with `view'
7875 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7878 *) Added psocket() which is a pool form of socket(), various places within
7879 the proxy weren't properly blocking alarms while registering the cleanup
7880 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7881 was a bug where the client socket was being close()d twice due a still
7882 registered cleanup. [Dean Gaudet]
7884 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7887 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7888 [Jason Venner <jason@idiom.com>] PR#667
7890 *) Enable ``=""'' for RewriteCond directives to match against
7891 the empty string. This is the preferred way instead of ``^$''.
7892 [Ralf S. Engelschall]
7894 *) Fixed an infinite loop in mod_imap for references above the server root
7895 [Dean Gaudet] PR#748
7897 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7898 SendBufferSize, so that the TCP window can be set appropriately
7899 for LFNs. [Phillip A. Prindeville]
7901 *) mod_browser has been replaced by the more general mod_setenvif
7902 (courtesy of Paul Sutton). BrowserMatch* directives are still
7903 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7904 UnSetEnvIfZero directives. [Ken Coar]
7906 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7907 order for remote_host to be set (for logging, or for the env var
7908 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7911 *) mod_access overhaul:
7912 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7913 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7914 - Critical path was sped up by pre-computing a few things at config time.
7915 - The undocumented syntax "allow user-agents" was removed,
7916 the replacement is "allow from env=foobar" combined with mod_browser.
7917 - When used with hostnames it now forces a double-reverse lookup
7918 no matter what the directory settings are. This double-reverse
7919 doesn't affect any of the other routines that use the remote
7920 hostname. In particular it's still passed to CGIs and the log
7921 without the double-reverse check. Related PR#860.
7924 *) When a large bwrite() occurs (larger than the internal buffer size),
7925 while there is already something in the buffer, apache will combine
7926 the large write and the buffer into a single writev(). (This is
7927 in anticipation of using mmap() for reading files.)
7930 *) In obscure cases where a partial socket write occurred while chunking,
7931 Apache would omit the chunk header/footer on the next block. Cleaned
7932 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7933 a bug where a long pause in DNS lookups could cause the last packet
7934 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7936 *) API: Added child_exit function to module structure. This is called
7937 once per "heavy-weight process" just before a server child exit()'s
7938 e.g. when max_requests_per_child is reached, etc.
7939 [Doug MacEachern, Dean Gaudet]
7941 *) mod_include cleanup showed that handle_else was being used to handle
7942 endif. It didn't cause problems, but it was cleaned up too.
7945 *) mod_cern_meta would attempt to find meta files for the directory itself
7946 in some cases, but not in others. It now avoids it in all cases.
7949 *) mod_mime_magic would core dump if there was a decompression error.
7950 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7952 *) PORT: some variants of DGUX require -lsocket -lnsl
7953 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7955 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7956 by the various fields (name, size, et cetera), either in ascending
7957 or descending order. Just click on the column header. [Ken Coar]
7959 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7960 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7961 the relatively safe direction. [Dean Gaudet] PR#344
7963 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7964 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7966 *) child_main avoids an unneeded call to select() when there is only one
7967 listening socket. [Dean Gaudet]
7969 *) In the event that the server is starved for idle servers it will
7970 spawn 1, then 2, then 4, ..., then 32 servers each second,
7971 doubling each second. It'll also give a warning in the errorlog
7972 since the most common reason for this is a poor StartServers
7973 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7974 the maximum. [Dean Gaudet]
7976 *) Apache now provides an effectively unbuffered connection for
7977 CGI scripts. This means that data will be sent to the client
7978 as soon as the CGI pauses or stops output; previously, Apache would
7979 buffer the output up to a fixed buffer size before sending, which
7980 could result in the user viewing an empty page until the CGI finished
7981 or output a complete buffer. It is no longer necessary to use an
7982 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7983 in a language that by default does buffering (e.g. perl) this
7984 shouldn't have a detrimental effect on performance.
7986 "nph-" CGIs, which formerly provided a direct socket to the client
7987 without any server post-processing, were not fully compatible with
7988 HTTP/1.1 or SSL support. As such they would have had to implement
7989 the transport details, such as encryption or chunking, in order
7990 to work properly in certain situations. Now, the only difference
7991 between nph and non-nph scripts is "non-parsed headers".

7994 *) If a BUFF is switched from buffered to unbuffered reading the first
7995 bread() will return whatever remained in the buffer prior to the
7996 switch. [Dean Gaudet]
7998 Changes with Apache 1.3a1
8000 *) Added another Configure helper script: TestLib. It determines
8001 if a specified library exists. [Jim Jagielski]
8003 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8004 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8007 *) PORT: Some architectures use size_t for various lengths in network
8008 functions such as accept(), and getsockname(). The definition
8009 NET_SIZE_T is used to control this. [Dean Gaudet]
8011 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8012 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8013 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8015 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8016 [Igor N Kovalenko <infoh@mail.wplus.net>]
8018 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8019 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8020 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8021 [Dean Gaudet] related PR#875
8023 *) API: Correct child_init() slot declaration from int to void, to
8024 match the init() declaration. Update mod_example to use the new

8041 *) AddModuleInfo directive for mod_info which allows you to annotate
8042 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8044 *) Added NoProxy directive to avoid using ProxyRemote for selected
8045 addresses. Added ProxyDomain directive to cause unqualified
8046 names to be qualified by redirection.
8047 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8049 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8050 header to the remote host in the proxy. [Sameer Parekh and
8053 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8054 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8055 URLs, fixed rewritelog(), fixed forced response code handling on
8056 redirects from within .htaccess files, disabled pipe locking under
8057 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8058 no substitution, bugfixed situations where HostnameLookups is off, made
8059 mod_rewrite more thread-safe for NT port and fixed problem when creating
8060 an empty query string via "xxx?".
8061 This update also removes the copyright of Ralf S. Engelschall,
8062 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8063 exclusively copyrighted by the Apache Group now. This happened because
8064 the author now has gifted mod_rewrite exclusively to the Apache Group and
8065 no longer maintains an external version.
8066 [Ralf S. Engelschall]
8068 *) API: Added child_init function to module structure. This is called
8069 once per "heavy-weight process" before any requests are handled.

8075 *) API: Added is_initial_req() which tests if the request being
8076 processed is the initial request, or a subrequest.

8080 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8082 *) Configure fixed to correctly propagate user-selected options and
8083 settings (such as CC and OPTIM) to Makefiles other than
8084 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8086 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8087 directory indices to start with the contents of the HeaderName file
8088 if there is one. If there isn't one, the behaviour is unchanged.
8089 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8091 *) WIN32: Modules can now be dynamically loaded DLLs using the
8092 LoadModule/LoadFile directives. Note that module DLLs must be
8093 compiled with the multithreaded DLL version of the runtime library.
8094 [Alexei Kosut and Ben Laurie]
8096 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8097 This allows the admin to completely remove automatic indexing
8098 from the server, while still supporting the basic functions of
8099 trailing-slash redirects and DirectoryIndex files. Note that if
8100 you're carrying over an old Configuration file and you use directory
8101 indexing then you'll want to add:
8103 Module autoindex_module mod_autoindex.o
8105 before mod_dir in your Configuration. [Dean Gaudet]
8107 *) popendir/pclosedir created to properly protect directory scanning.
8108 [Dean Gaudet] PR#525
8110 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8111 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8112 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8115 *) The AccessFileName directive can now take more than one filename.
8116 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8118 *) The new mod_mime_magic can be used to "magically" determine the type
8119 of a file if the extension is unknown. Based on the unix file(1)
8120 command. [Ian Kluft <ikluft@cisco.com>]
8122 *) We now determine and display the time spent processing a
8123 request if desired. [Jim Jagielski]
8125 *) mod_status: PID field of "dead" child slots no longer displays
8126 main httpd process's PID. [Jim Jagielski]
8128 *) Makefile.nt added - to build all the bits from the command line:
8129 nmake -f Makefile.nt
8130 Doesn't yet work properly. [Ben Laurie]
8132 *) Default text of 404 error is now "Not Found" rather than the
8133 potentially misleading "File Not Found". [Ken Coar]
8135 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8136 for the net if we require people that actually need this data to
8137 enable it. [Linus Torvalds]
8139 *) directory_walk() is an expensive function, keep a little more state to
8140 avoid needless string counting. Add two new functions make_dirstr_parent
8141 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8142 The new functions are a little less general than make_dirstr, but
8143 work more efficiently (less memory, less string counting).
8146 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8147 to LDFLAGS) to avoid complications with lex rules in make files.
8148 [Dean Gaudet] PR#372
8150 *) run_method optimized to avoid needless scanning over NULLs in the
8151 module list. [Dean Gaudet]
8153 *) Revamp of (unix) scoreboard management code such that it avoids
8154 unnecessary traversals of the scoreboard on each hit. This is
8155 particularly important for high volume sites with a large
8156 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8157 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8158 httpd.h. [Dean Gaudet]
8160 *) In configurations using multiple Listen statements it was possible for
8161 busy sockets to starve other sockets of service. [Dean Gaudet]
8163 *) Added hook so standalone_main can be replaced at compile time
8164 (define STANDALONE_MAIN)
8167 *) Lowest-level read/write functions in buff.c will be replaced with
8168 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8169 compile time. The default sfio discipline will behave as apache
8170 would without sfio compiled in.
8173 *) Enhance UserDir directive (mod_userdir) to accept a list of
8174 usernames for the 'disable' keyword, and add 'enable user...' to
8175 selectively *en*able userdirs if they're globally disabled.
8178 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8179 will work with Netscape dbm files. (dbmmanage will probably not
8180 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8182 *) Add a ListenBacklog directive to control the backlog parameter
8183 passed to listen(). Also change the default to 511 from 512.
8186 *) API: A new handler response DONE which informs apache that the
8187 request has been handled and it can finish off quickly, similar to
8188 how it handles errors. [Rob Hartill]
8190 *) Turn off chunked encoding after sending terminating chunk/footer
8191 so that we can't do it twice by accident. [Roy Fielding]
8193 *) mod_expire also issues Cache-Control: max-age headers.
8196 *) API: Added kill_only_once option for free_proc_chain so that it won't
8197 aggressively try to kill off specific children. For fastcgi.
8198 [Stanley Gambarin <gambarin@OpenMarket.com>]
8200 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8202 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8203 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8204 attributes in the FancyIndexing IMG tags. [Ken Coar]
8206 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8208 *) PORT: Added Windows NT support
8209 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8211 Changes with Apache 1.2.6
8213 *) mod_include when using XBitHack Full would send ETags in addition to
8214 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8215 [Dean Gaudet] PR#1133
8217 *) SECURITY: When a client connects to a particular port/addr, and
8218 gives a Host: header ensure that the virtual host requested can
8219 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8221 *) Support virtual hosts with wildcard port and/or multiple ports
8222 properly. [Ed Korthof <ed@organic.com>]
8224 *) Fixed some case-sensitivity issues according to RFC2068.
8227 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8228 and mod_include.c. [Dean Gaudet]
8230 *) Variable 'cwd' was being used pointlessly before being set.
8233 *) SIGURG doesn't exist on all platforms.
8234 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8236 *) When an error occurs during a POST, or other operation with a
8237 request body, the body has to be read from the net before allowing
8238 a keepalive session to continue. [Roy Fielding] PR#1399
8240 *) When an error occurs in fcntl() locking suggest the user look up
8241 the docs for LockFile. [Dean Gaudet]
8243 *) table_set() and table_unset() did not deal correctly with
8244 multiple occurrences of the same key. [Stephen Scheck
8245 <sscheck@infonex.net>, Ben Laurie] PR#1604
8247 *) send_fd_length() did not calculate total_bytes_sent properly in error
8248 cases. [Ben Reser <breser@regnow.com>] PR#1366
8250 *) r->connection->user was allocated in the wrong pool causing corruption
8251 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8253 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8254 Also removed the auto-generated link to www.apache.org that was the
8255 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8257 *) Multiple "close" tokens may have been set in the "Connection"
8258 header, not an error, but a waste.
8259 [Ronald.Tschalaer@psi.ch] PR#1683
8261 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8262 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8264 *) It appears the "257th byte" bug (see
8265 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8266 at the 256th byte as well. Fixed. [Dean Gaudet]
8268 *) mod_rewrite would not handle %3f properly in some situations.
8271 *) Apache could generate improperly chunked HTTP/1.1 responses when
8272 the bputc() or rputc() functions were used by modules (such as
8273 mod_include). [Dean Gaudet]
8275 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8276 some ports. [Ralf Engelschall]
8278 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8280 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8282 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8284 Changes with Apache 1.2.5
8286 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8287 only an issue on systems without a MAXDNAME define or where
8288 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8290 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8293 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8294 directory listings. [Marc Slemko]
8296 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8299 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8300 is used to read various types of files such as htaccess and
8301 htpasswd files. [Marc Slemko]
8303 *) SECURITY: Ensure that the buffer returned by ht_time is always
8304 properly null terminated. [Marc Slemko]
8306 *) SECURITY: General mod_include cleanup, including fixing several
8307 possible buffer overflows and a possible infinite loop. This cleanup
8308 was done against 1.3 code and then backported to 1.2, the result
8309 is a large difference (due to indentation cleanup in 1.3 code).
8310 Users interested in seeing a smaller set of relevant differences
8311 should consider comparing against src/modules/standard/mod_include.c
8312 from the 1.3b3 release. Non-indentation changes to mod_include
8313 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8315 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8316 including fixing a possible buffer overflow. This cleanup also
8317 was done with 1.3 code as a basis, see the the previous note
8318 about mod_include. [Dean Gaudet]
8320 *) SECURITY: If a htaccess file can not be read due to bad
8321 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8322 The previous behavior was to ignore the htaccess file if it could not
8323 be read. This change may make some setups with unreadable
8324 htaccess files stop working. PR#817 [Marc Slemko]
8326 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8327 Make it O(n). This inefficiency could be used to mount a denial
8328 of service attack against the Apache server. Thanks to

8361 on this platform. [Marc Slemko]
8363 Changes with Apache 1.2.3
8365 *) The request to a remote proxy was mangled if it was generated as the
8366 result of a ProxyPass directive. URL schemes other than http:// were not
8367 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

8381 happily skip past access checks on subdirectories looked up with relative
8382 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8385 *) Add lockfile name to error message printed out when
8386 USE_FLOCK_SERIALIZED_ACCEPT is defined.

8393 a vhost, put the main server's first and the vhost's second. Otherwise
8394 the vhost can't override the main server. [Dean Gaudet] PR#717

8401 [Dean Gaudet] PR#748
8403 *) mod_include cleanup showed that handle_else was being used to handle
8404 endif. It didn't cause problems, but it was cleaned up too.
8407 *) Last official synchronization of mod_rewrite with author version (because
8408 mod_rewrite is now directly developed by the author at the Apache Group):
8409 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8410 minus WIN32/NT stuff, but plus copyright removement.

8509 *) Attempt to work around problems with third party libraries that do not
8510 handle high numbered descriptors (examples include bind, and
8511 solaris libc). On all systems apache attempts to keep all permanent
8512 descriptors above 15 (called the low slack line). Solaris users
8513 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8514 which keeps all non-FILE * descriptors above 255. On all systems
8515 this should make supporting large numbers of vhosts with many open
8516 log files more feasible. If this causes trouble please report it,
8517 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8518 [Dean Gaudet] various PRs
8520 *) Related to the last entry, network sockets are now opened before
8521 log files are opened. The only known case where this can cause
8522 problems is under Solaris with many virtualhosts and many Listen
8523 directives. But using -DHIGH_SLACK_LINE=256 described above will
8524 work around this problem. [Dean Gaudet]
8526 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8529 *) Improved unix error response logging. [Marc Slemko]
8531 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8532 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8533 when a URL http://... was used in conjunction with a special
8534 redirect flag, e.g. R=permanent, the permanent status was lost.

8579 reading from one buffer and writing to another, at least until it has
8580 a custom timeout handler. [Roy Fielding and Petr Lampa]

8595 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8596 [Chuck Murcko] PR#614
8598 *) If multiple requests on a single connection are used to retrieve
8599 data from different virtual hosts, the virtual host list would be
8600 scanned starting with the most recently used VH instead of the first,
8601 causing most virtual hosts to be ignored.

8615 *) If a soft_timeout occurs after keepalive is set, then the main child
8616 loop would try to read another request even though the connection
8617 has been aborted. [Roy Fielding]
8619 *) Configure changes: Allow for whitespace at the start of a
8620 Module declaration. Also, be more understanding about the
8621 CC=/OPTIM= format in Configuration. Finally, fix compiler
8622 flags if using HP-UX's cc compiler. [Jim Jagielski]
8624 *) Subrequests and internal redirects now inherit the_request from the
8625 original request-line. [Roy Fielding]
8627 *) Test for error conditions before creating output header fields, since
8628 we don't want the error message to include those fields. Likewise,
8629 reset the content_language(s) and content_encoding of the response
8630 before generating or redirecting to an error message, since the new
8631 message will have its own Content-* definitions. [Dean Gaudet]
8633 *) Restored the semantics of headers_out (headers sent only with 200..299
8634 and 304 responses) and err_headers_out (headers sent with all responses).
8635 Avoid the overhead of copying tables if err_headers_out is empty
8636 (the usual case). [Roy Fielding]
8638 *) Fixed a couple places where a check for the default Content-Type was
8639 not properly checking both the value configured by the DefaultType
8640 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8641 of DEFAULT_TYPE to match the documented default (text/plain).

8644 *) Escape the HTML-sensitive characters in the Request-URI that is
8645 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8647 *) Properly initialize the flock structures used by the mutex locking
8648 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8651 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8652 (and NCSA httpd) definition wherein it was the extra path info beyond
8653 the CGI script filename. The environment variable FILEPATH_INFO has
8654 been removed, and instead we supply the original REQUEST_URI to any
8655 script that wants to be Apache-specific and needs the real URI path.
8656 This solves a problem with existing scripts that use extra path info
8657 in the ScriptAlias directive to pass options to the CGI script.
8660 *) The _default_ change in 1.2b10 will change the behaviour on configs
8661 that use multiple Listen statements for listening on multiple ports.
8662 But that change is necessary to make _default_ consistent with other
8663 forms of <VirtualHost>. It requires such configs to be modified
8664 to use <VirtualHost _default_:*>. The documentation has been
8665 updated. [Dean Gaudet] PR#530
8667 *) If an ErrorDocument CGI script is used to respond to an error
8668 generated by another CGI script which has already read the message
8669 body of the request, the server would block trying to read the
8670 message body again. [Rob Hartill]

8694 changes and in anticipation of 1.2 final release. [Roy Fielding]
8696 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8697 the connection (e.g., when user presses Stop). Apache will now stop
8698 trying to send a message body immediately after an error from write.
8699 [Roy Fielding and Nathan Kurz] PR#335
8701 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8702 than mod_alias, and mod_alias has higher priority than mod_proxy;
8703 rearranged other modules to enhance understanding of their purpose
8704 and relative order (and maybe even reduce some overhead).

8707 *) Fix graceful restart. Eliminate many signal-related race
8708 conditions in both forms of restart, and in SIGTERM. See
8709 htdocs/manual/stopping.html for details on stopping and
8710 restarting the parent. [Dean Gaudet]
8712 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8713 memory allocator to avoid a behaviour that required extra blocks to
8714 be allocated. [Dean Gaudet]
8716 *) Allow suexec to access files relative to current directory but not

8720 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8721 PR#367, 368, 354, 453

8724 while obtaining the /~user and save the username in a separate data
8725 area so that it won't be overwritten by the call to getgrgid(), and
8726 fix some misuse of the pool string allocation functions. Also fixes
8727 a general problem with parsing URL query info into args for CGI scripts.

8739 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8740 object that can't be PUT, or FOOBAR for some method FOOBAR that
8741 apache doesn't know about at all). Log 404s that occur in mod_include.
8742 [Paul Sutton, John Van Essen]
8744 *) If a soft timeout (or lingerout) occurs while trying to flush a
8745 buffer or write inside buff.c or fread'ing from a CGI's output,
8746 then the timeout would be ignored. [Roy Fielding] PR#373
8748 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8749 parsing of headers. If the terminating empty-line CRLF occurs starting
8750 at the 256th or 257th byte of output, then Navigator will think a normal
8751 image is invalid. We are guessing that this is because their initial
8752 read of a new request uses a 256 byte buffer. We check the bytes written
8753 so far and, if we are about to tickle the bug, we instead insert a
8754 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8756 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8757 of an external redirection. [Roy Fielding and Paul Sutton]
8759 *) Configure would create a broken Makefile if the configuration file
8760 contained a commented-out Rule. [Roy Fielding]
8762 *) Promote per_dir_config and subprocess_env from the subrequest to the
8763 main request in mod_negotiation. In particular this fixes a bug
8764 where <Files> sections wouldn't properly apply to negotiated content.
8767 *) Fix a potential deadlock in mod_cgi script_err handling.
8768 [Ralf S. Engelschall]
8770 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8773 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8774 .htaccess files because the RewriteBase was not replaced correctly.
8775 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8776 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8778 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8779 1.x the settings are those of pre-1.2b8. For 2.x we include
8780 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8781 HAVE_SYS_RESOURCE_H (enable the RLimit commands).

8791 *) Add UnixWare compile/install instructions. [Chuck Murcko]

8795 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8797 *) Improve handling of directories when filenames have spaces in them.
8800 *) For hosts with multiple IP addresses, try all additional addresses if
8801 necessary to get a connect. Fail only if hostent address list is
8802 exhausted. [Chuck Murcko]
8804 *) More signed/unsigned port fixes. [Dean Gaudet]
8806 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8809 Changes with Apache 1.2b8
8811 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8812 to it. [Marc Slemko]
8814 *) The addition of <Location> and <File> directives made the
8815 sub_req_lookup_simple() function bogus, so we now handle
8816 the special cases directly. [Dean Gaudet]
8818 *) We now try to log where the server is dumping core when a fatal
8819 signal is received. [Ken Coar]
8821 *) Improved lingering_close by adding a special timeout, removing the
8822 spurious log messages, removing the nonblocking settings (they
8823 are not needed with the better timeout), and adding commentary
8824 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8825 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8827 *) Send error messages about setsockopt failures to the server error
8828 log instead of stderr. [Roy Fielding]
8830 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8832 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8833 processing a subrequest, allocate memory from r->main->pool instead
8834 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8835 in the middle of an SSI request. [Dean Gaudet] PR #122
8837 *) Fixed status of response when POST is received for a nonexistent URL
8838 (was sending 405, now 404) and when any method is sent with a
8839 full-URI that doesn't match the server and the server is not acting
8840 as a proxy (was sending 501, now 403). [Roy Fielding]
8842 *) Host port changed to unsigned short. [Ken Coar] PR #276
8844 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8846 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8848 *) Report extra info from errno with many errors that cause httpd to exit.
8849 spawn_child, popenf, and pclosef now have valid errno returns in the
8850 event of an error. Correct problems where errno was stomped on
8851 before being reported. [Dean Gaudet]
8853 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8854 never called, and thus the filesystem would remain full indefinitely.
8855 We now also remove incomplete cache files left if the origin server
8856 didn't send a Content-Length header and either the client has aborted
8857 transfer or bwrite() to client has failed. [Petr Lampa]
8859 *) Fixed the handling of module and script-added header fields.
8860 Improved the interface for sending header fields and reduced
8861 the duplication of code between sending okay responses and errors.
8862 We now always send both headers_out and err_headers_out, and
8863 ensure that the server-reserved fields are not being overridden,
8864 while not overriding those that are not reserved. [Roy Fielding]
8866 *) Moved transparent content negotiation fields to err_headers_out
8867 to reflect above changes. [Petr Lampa]
8869 *) Fixed the determination of whether or not we should make the
8870 connection persistent for all of the cases where some other part
8871 of the server has already indicated that we should not. Also
8872 improved the ordering of the test so that chunked encoding will
8873 be set whenever it is desired instead of only when KeepAlive
8874 is enabled. Added persistent connection capability for most error
8875 responses (those that do not indicate a bad input stream) when
8876 accessed by an HTTP/1.1 client. [Roy Fielding]
8878 *) Added missing timeouts for sending header fields, error responses,
8879 and the last chunk of chunked encoding, each of which could have
8880 resulted in a process being stuck in write forever. Using soft_timeout
8881 requires that the sender check for an aborted connection rather than
8882 continuing after an EINTR. Timeouts that used to be initiated before
8883 send_http_header (and never killed) are now initiated only within or
8884 around the routines that actually do the sending, and not allowed to
8885 propagate above the caller. [Roy Fielding]
8887 *) mod_auth_anon required an @ or a . in the email address, not both.
8890 *) per_dir_defaults weren't set correctly until directory_walk for
8891 name-based vhosts. This fixes an obscure bug with the wrong config
8892 info being used for vhosts that share the same ip as the server.
8895 *) Improved generation of modules/Makefile to be more generic for
8896 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8898 *) Generate makefile dependency for Configuration based on the actual
8899 name given when running the Configure process. [Dean Gaudet]
8901 *) Fixed problem with vhost error log not being set prior to
8902 initializing virtual hosts. [Dean Gaudet]
8904 *) Fixed infinite loop when a trailing slash is included after a type map
8905 file URL (extra path info). [Petr Lampa]
8907 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8909 *) Add documentation for DNS issues (reliability and security), and try
8910 to explain the virtual host matching process. [Dean Gaudet]
8912 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8913 fails while parsing the configuration file. [Dean Gaudet]
8915 *) Improved calls to setsockopt. [Roy Fielding]
8917 *) Negotiation changes: Don't output empty content-type in variant list;
8918 Output charset in variant list; Return sooner from handle_multi() if
8919 no variants found; Add handling of '*' wildcard in Accept-Charset.
8920 [Petr Lampa and Paul Sutton]
8922 *) Fixed overlaying of request/sub-request notes and headers in
8923 mod_negotiation. [Dean Gaudet]
8925 *) If two variants' charset quality are equal and one is the default
8926 charset (iso-8859-1), then prefer the variant that was specifically
8927 listed in Accept-Charset instead of the default. [Petr Lampa]
8929 *) Memory allocation problem in push_array() -- it would corrupt memory
8930 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8932 *) invoke_handler() doesn't handle mime arguments in content-type
8935 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8938 *) Fixed problem with ErrorDocument not working for virtual hosts
8939 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8941 *) Log an error message if we get a request header that is too long,
8942 since it may indicate a buffer overflow attack. [Marc Slemko]
8944 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8945 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8946 [Ken Coar] PR #146, #187

8952 [Garey Smiley] PR #59
8954 *) Fixed error message when resource is not found and URL contains
8955 path info. [Petr Lampa and Dean Gaudet] PR #40
8957 *) Fixed user and server confusion over what should be a virtual host
8958 and what is the main server, resulting in access to something
8959 other than the name defined in the virtualhost directive (but
8960 with the same IP address) failing. [Dean Gaudet]
8962 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8963 AIX; improves the redirection stuff to enable the users to generally
8964 redirect to http, https, gopher and ftp; added TIME variable for
8965 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8966 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8967 can be used in conjunction with %{TIME} or other variables to create
8968 time-dependent rewriting rules. [Ralf S. Engelschall]
8970 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8971 Module authors may need to adjust their code for proper cleanup to take
8972 place (that is, call note_cleanups_for_fd()). This change fixes problems
8973 with file descriptors being erroneously closed when the proxy module was
8974 in use. [Ben Laurie]
8976 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8977 initgroups() to hose the group information needed for later
8978 comparisons. [Randy Terbush]
8980 *) Remove unnecessary call to va_end() in create_argv() which
8981 caused a SEGV on some systems.
8983 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8986 *) Clear memory allocated for listeners. [Randy Terbush]

9015 perhaps questionable, they appear to be legal by RFC 959.

9045 the socket is not connected (reset by client). [Roy Fielding]
9047 *) Rearranged main child loop to remove duplication of code in
9048 select/accept and keep-alive requests, fixed several bugs regarding
9049 checking scoreboard_image for exit indication and failure to
9050 account for all success conditions and trap all error conditions,
9051 prevented multiple flushes before closing the socket; close the entire
9052 socket buffer instead of just one descriptor, prevent logging of
9053 EPROTO and ECONNABORTED on platforms where supported, and generally
9054 improved readability. [Roy Fielding]
9056 *) Extensive performance improvements. Cleaned up inefficient use of
9057 auto initializers, multiple is_matchexp calls on a static string,
9058 and excessive merging of response_code_strings. [Dean Gaudet]
9060 *) Added double-buffering to mod_include to improve performance on
9061 server-side includes. [Marc Slemko]
9063 *) Several fixes for suexec wrapper. [Randy Terbush]
9064 - Make wrapper work for files on NFS filesystem.
9065 - Fix portability problem of MAXPATHLEN.
9066 - Fix array overrun problem in clean_env().
9067 - Fix allocation of PATH environment variable
9069 *) Removed extraneous blank line is description of mod_status chars.
9072 *) Logging of errors from the call_exec routine simply went nowhere,
9073 since the logfile fd has been closed, so now we send them to stderr.
9074 [Harald T. Alvestrand]
9076 *) Fixed core dump when DocumentRoot is a CGI.
9077 [Ben Laurie, reported by geddis@tesserae.com]
9079 *) Fixed potential file descriptor leak in mod_asis; updated it and
9080 http_core to use pfopen/pfclose instead of fopen/fclose.
9081 [Randy Terbush and Roy Fielding]
9083 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9084 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9085 [Dean Gaudet and Ken Coar]
9087 *) Return a 302 response code to the client when sending a redirect
9088 due to a missing trailing '/' on a directory instead of a 301; now
9089 it is cacheable. [Markus Gyger]
9091 *) Fix condition where, if a bad directive occurs in .htaccess, and
9092 sub_request() goes first to this directory, then log_reason() will
9093 SIGSEGV because it doesn't have initialized r->per_dir_config.
9094 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9096 *) Fix handling of lang_index in is_variant_better(). This was
9097 causing problems which resulted in the server sending the
9098 wrong language document in some cases. [Petr Lampa]
9100 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9101 the clean environment on some systems.
9103 *) Tweak byteserving code (e.g. serving PDF files) to work around
9104 bugs in Netscape Navigator and Microsoft Internet Explorer.
9105 Emit Content-Length header when sending multipart/byteranges.
9108 *) Port to HI-UX/WE2. [Nick Maclaren]
9110 *) Port to HP MPE operating system for HP 3000 machines
9111 [Mark Bixby <markb@cccd.edu>]
9113 *) Fixed bug which caused a segmentation fault if only one argument
9114 given to RLimit* directives. [Ed Korthof]
9116 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9118 *) Improved buffered output to the client by delaying the flush decision
9119 until the BUFF code is actually about to read the next request.
9120 This fixes a problem introduced in 1.2b5 with clients that send
9121 an extra CRLF after a POST request. Also improved chunked output
9122 performance by combining writes using writev() and removing as
9123 many bflush() calls as possible. NOTE: Platforms without writev()
9124 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9125 or Configure, unless we have already done so. [Dean Gaudet]
9127 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9129 *) Fixed mod_info output corruption bug introduced by buffer overflow
9130 fixes. [Dean Gaudet]
9132 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9133 for the special case of a 304 response. [Paul Sutton]
9135 *) Improved handling of TRACE method by bypassing normal method handling
9136 and header parsing routines; fixed Allow response to always allow TRACE.
9139 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9141 *) Cleaned-up some of the generated HTML. [Ken Coar]
9143 Changes with Apache 1.2b6
9145 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9147 *) Fix typo introduced in fix for potential infinite loop around
9148 accept() in child_main(). This change caused the rev to 1.2b6.
9149 1.2b5 was never a public beta.
9151 Changes with Apache 1.2b5
9153 *) Change KeepAlive semantics (On|Off instead of a number), add
9154 MaxKeepAliveRequests directive. [Alexei Kosut]
9156 *) Various NeXT compilation patches, as well as a change in
9157 regex/regcomp.c since that file also used a NEXT define.
9160 *) Allow * to terminate the end of a directory match in mod_dir.
9161 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9163 *) Don't call can_exec() if suexec_enabled. Calling this requires
9164 scripts executed by the suexec wrapper to be world executable, which
9165 defeats one of the advantages of running the wrapper. [Randy Terbush]
9167 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9170 *) Migration from sprintf() to snprintf() to avoid buffer
9171 overflows. [Marc Slemko]
9173 *) Provide portable snprintf() implementation (ap_snprintf)
9174 as well as *cvt family. [Jim Jagielski]
9176 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9179 *) Remove mod_fastcgi.c from the distribution. This module appears
9180 to be maintained more through the Open Market channels and should
9181 continue to be easily available at http://www.fastcgi.com/
9183 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9184 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9186 *) mod_info assumed that the config files were relative to ServerRoot.
9189 *) CGI scripts called as an error document resulting from failed
9190 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9192 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9195 *) Properly check errno to prevent display of a directory index
9196 when server receives a long enough URL to confuse stat().
9199 *) Several security enhancements to suexec wrapper. It is _highly_
9200 recommended that previously installed versions of the wrapper
9201 be replaced with this version. [Randy Terbush, Jason Dour]
9203 - ~user execution now properly restricted to ~user's home
9204 directory and below.
9205 - execution restricted to UID/GID > 100
9206 - restrict passed environment to known variables
9207 - call setgid() before initgroups() (portability fix)
9208 - remove use of setenv() (portability fix)
9210 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9212 *) Add access control via environment variables. [Ben Laurie]
9214 *) Add rflush() function. [Alexei Kosut]
9216 *) remove duplicate pcalloc() call in new_connection().
9218 *) Fix incorrect comparison which could allow number of children =
9219 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9220 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9222 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9223 AIX PS/2, CONVEXOS. [Jim Jagielski]
9225 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9226 It's more portable. [Martin Kraemer]
9228 *) Replace references to make in Makefile.tmpl with $(MAKE).
9231 *) Add ProxyBlock directive w/IP address caching. Add IP address
9232 caching to NoCache directive as well. ProxyBlock works with all
9233 handlers; NoCache now also works with FTP for anonymous logins.
9234 Still more code cleanup. [Chuck Murcko]
9236 *) Add "header parse" API hook [Ben Laurie]
9238 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9240 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9242 *) Correctly allow access and auth directives in <Files> sections in
9243 server config files. [Alexei Kosut]
9245 *) Fix bug with ServerPath that could cause certain files to be not
9246 found by the server. [Alexei Kosut]
9248 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9249 double-quote from text and so that it properly checks for unsupported
9250 status codes using the new index_of_response interface. [Roy Fielding]
9252 *) Multiple fixes to the lingering_close code in order to avoid being
9253 interrupted by a stray timeout, to avoid lingering on a connection
9254 that has already been aborted or never really existed, to ensure that
9255 we stop lingering as soon as any error condition is received, and to
9256 prevent being stuck indefinitely if the read blocks. Also improves
9257 reporting of error conditions. [Marc Slemko and Roy Fielding]
9259 *) Fixed initialization of parameter structure for sigaction.
9260 [mgyger@itr.ch, Adrian Filipi-Martin]
9262 *) Fixed reinitializing the parameters before each call to accept and
9263 select, and removed potential for infinite loop in accept.
9264 [Roy Fielding, after useful PR from adrian@virginia.edu]
9266 *) Fixed condition where, if a child fails to fork, the scoreboard would
9267 continue to say SERVER_STARTING forever. Eventually, the main process
9268 would refuse to start new children because count_idle_servers() will
9269 count those SERVER_STARTING entries and will always report that there
9270 are enough idle servers. [Phillip Vandry]
9272 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9273 Avoided calling bflush() when the client is pipelining requests.
9274 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9276 *) Added description of "." mode in server-status [Jim Jagielski]
9278 Changes with Apache 1.2b4
9280 *) Fix possible race condition in accept_mutex_init() that
9281 could leave a small security hole open allowing files to be
9282 overwritten in cases where the server UID has write permissions.
9285 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9287 *) Fix portablity problem in util_script where ARG_MAX may not be
9288 defined for some systems.
9290 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9293 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9294 style magic #! token for better script portability. [Garey Smiley]
9296 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9297 execution for ~userdir CGI. [Jason Dour]
9299 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9301 *) Fix month off by one in suexec wrapper logging.
9303 Changes with Apache 1.2b3:
9305 *) Fix error in mod_cgi which could cause resources not to be properly
9306 freed, or worse. [Dean Gaudet]
9308 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9310 *) Add set_flag_slot() at the request of Dirk and others.
9313 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9315 *) Add changes to improve the error message given for invalid
9316 ServerName parameters. [Dirk vanGulik]
9318 *) Add "Authoritative" directive for Auth modules that don't
9319 currently have it. This gives admin control to assign authoritative
9320 control to an authentication scheme and allow "fall through" for
9321 those authentication modules that aren't "Authoritative" thereby
9322 allowing multiple authentication mechanisms to be chained.
9325 *) Remove requirement for ResourceConfig/AccessConfig if not using
9326 the three config file layout. [Randy Terbush]
9328 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9330 *) Changes to suexec wrapper to fix the following problems:
9331 1. symlinked homedirs will kill ~userdirs.
9332 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9333 3. CGI command lines paramters problems
9334 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9335 [Randy Terbush, Jason Dour]
9337 *) Change create_argv() to accept variable arguments. This fixes
9338 a problem where arguments were not getting passed to the CGI via
9339 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9341 *) Collapse multiple slashes in path URLs to properly apply
9342 handlers defined by <Location>. [Alexei Kosut]
9344 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9346 *) Improve the accuracy of request duration timings by setting
9347 r->request_time in read_request_line() instead of read_request().
9350 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9351 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9353 *) Add the ability to pass different Makefile.tmpl files to Configure
9354 using the -make flag. [Rob Hartill]
9356 *) Fix coredump triggered when sending a SIGHUP to the server caused
9357 by an assertion failure, in turn caused by an uninitialised field in a
9361 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9362 PATH_INFO from previous versions of Apache (in certain situations,
9363 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9364 [later removed in 1.2b11]
9366 *) Add rwrite() function to API to allow for sending strings of
9367 arbitrary length. [Doug MacEachern]
9369 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9371 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9372 NeXT. [Jim Jagielski]
9374 *) Removed recent modification to promote the status code on internal
9375 redirects, since the correct fix was to change the default log format
9376 in mod_log_config so that it outputs the original status. [Rob Hartill]
9378 Changes with Apache 1.2b2:
9380 *) Update set_signals() to use sigaction() for setting handlers.
9381 This appears to fix a re-entrant problem in the seg_fault()
9382 bus_error() handlers. [Randy Terbush]
9384 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9386 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9388 *) proxy_http.c bugfixes: [Chuck Murcko]
9389 1) fixes possible NULL pointer reference w/NoCache
9390 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9391 host would cache nothing if it was in the local domain,
9392 and the local domain was in the NoCache list)
9393 3) Adds Host: header when not available
9394 4) Some code cleanup and clarification
9396 *) mod_include.c bugfixes:
9397 1) Fixed an ommission that caused include variables to not
9398 be parsed in config errmsg directives [Howard Fear]
9399 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9400 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9401 4) Allow backslash-escaping to all quoted text
9402 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9403 5) Pass variable to command line if not set in XSSI's env
9406 *) Fix infinite loop when processing Content-language lines in
9407 type-map files. [Alexei Kosut]
9409 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9411 *) Fixed problem in set_[user|group] that prevented CGI execution
9412 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9414 *) Added PORTING information file. [Jim Jagielski]
9416 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9418 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9420 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9421 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9423 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9424 which caused problems of systems where socket s_addr is >32bits.
9426 *) Added comment to explain (r->chunked = 1) side-effect in
9427 http_protocol.c [Roy Fielding]
9429 *) Replaced use of index() in mod_expires.c with more appropriate
9430 and portable isdigit() test. [Ben Laurie]
9432 *) Updated Configure for ...
9433 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9434 *-dg-dgux* (bad pattern match)
9435 QNX (DEF_WANTHSREGEX=yes)
9436 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9439 and added some user diagnostic info. [Ben Laurie]
9441 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9442 for better portability. [Jim Jagielski]
9444 *) Updated helpers/GuessOS for ...
9445 SCO 5 (recognize minor releases)
9446 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9447 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9448 IRIX64 (-sgi-irix64)
9449 ULTRIX (-unknown-ultrix)
9450 SINIX (-whatever-sysv4)
9451 NCR Unix (-ncr-sysv4)
9452 and fixed something in helpers/PrintPath [Ben Laurie]
9454 Changes with Apache 1.2b1
9456 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9458 Changes with Apache 1.1.1
9460 *) Fixed bug where Cookie module would make two entries in the
9461 logfile for each access [Mark Cox]
9463 *) Fixed bug where Redirect in .htaccess files would cause memory
9464 leak. [Nathan Neulinger]
9466 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9468 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9470 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9472 Changes with Apache 1.1.0
9474 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9476 *) Bring QNX support up to date. [Ben Laurie]
9478 *) Make virtual hosts default to main server keepalive parameters.
9479 [Alexei Kosut, Ben Laurie]
9481 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9483 *) Fix missing address family for connect, also remove unreachable statement
9484 in mod_proxy. [Ben Laurie]
9486 *) mod_env now turned on by default in Configuration.tmpl.
9488 *) Bugs which were fixed:
9489 a) yet more mod_proxy bugs [Ben Laurie]
9490 b) CGI works again with inetd [Alexei Kosut]
9491 c) Leading colons were stripped from passwords [osm@interguide.com]
9492 d) Another fix to multi-method Limit problem [jk@tools.de]
9494 Changes with Apache 1.1b4
9496 *) r->bytes_sent variable restored. [Robert Thau]
9498 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9500 *) More possibly unsecure programs removed from the support directory.
9502 *) More mod_auth_msql authentication improvements.
9504 *) VirtualHosts based on Host: headers no longer conflict with the
9507 *) OS/2 compatibility enhancements. [Gary Smiley]
9509 *) POST now allowed to directory index CGI scripts.
9511 *) Actions now work with files of the default type.
9513 *) Bugs which were fixed:
9514 a) more mod_proxy bugs
9515 b) early termination of inetd requests
9516 c) compile warnings on several systems
9517 d) problems when scripts stop reading output early
9519 Changes with Apache 1.1b3
9521 *) Much of cgi-bin and all of cgi-src has been removed, due to
9522 various security holes found and that we could no longer support
9525 *) The "Set-Cookie" header is now special-cased to not merge multiple
9526 instances, since certain popular browsers can not handle multiple
9527 Set-Cookie instructions in a single header. [Paul Sutton]
9529 *) rprintf() added to buffer code, occurrences of sprintf removed.
9532 *) CONNECT method for proxy module, which means tunneling SSL should work.
9533 (No crypto needed) Also a NoCache config directive.
9535 *) Several API additions: pstrndup(), table_unset() and get_token()
9536 functions now available to modules.
9538 *) mod_imap fixups, in particular Location: headers are now complete
9541 *) New "info" module which reports on installed module set through a
9542 special URL, a la mod_status.
9544 *) "ServerPath" directive added - allows for graceful transition
9545 for Host:-header-based virtual hosts.
9547 *) Anonymous authentication module improvements.
9549 *) MSQL authentication module improvements.
9551 *) Status module design improved - output now table-based. [Ben Laurie]
9553 *) htdigest utility included for use with digest authentication
9556 *) mod_negotiation: Accept values with wildcards to be treated with
9557 less priority than those without wildcards at the same quality
9558 value. [Alexei Kosut]
9560 *) Bugs which were fixed:
9561 a) numerous mod_proxy bugs
9562 b) CGI early-termination bug [Ben Laurie]
9563 c) Keepalives not working with virtual hosts
9564 d) RefererIgnore problems
9565 e) closing fd's twice in mod_include (causing core dumps on
9566 Linux and elsewhere).
9568 Changes with Apache 1.1b2
9571 a) core dumps in mod_digest
9572 b) truncated hostnames/ip address in the logs
9573 c) relative URL's in mod_imap map files
9575 Changes with Apache 1.1b1
9577 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9579 Changes with Apache 1.0.3
9581 *) Internal redirects which occur in mod_dir.c now preserve the
9582 query portion of a request (the bit after the question mark).
9585 *) Escape active characters '<', '>' and '&' in html output in
9586 directory listings, error messages and redirection links.
9589 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9591 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9594 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9596 *) Reset timeout timer after each successful fwrite() to the network.
9597 This patch adds a reset_timeout() procedure that is called by
9598 send_fd() to reset the timeout ever time data is written to the net.
9601 *) timeout() signal handler now checks for SIGPIPE and reports
9602 lost connections in a more user friendly way. [Rob Hartill]
9604 *) Location of the "scoreboard" file which used to live in /tmp is
9605 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9606 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9608 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9610 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9611 which caused a SEGV with cookies enabled
9613 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9616 *) Log the UNIX textual error returned by some system calls, in
9617 particular errors from accept() [David Robinson]
9619 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9621 Changes with Apache 1.0.2
9623 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9624 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9626 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9629 *) past changes to http_config.c to only use the
9630 setrlimit function on systems defining RLIMIT_NOFILE
9631 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9632 for SUNOS and prototypes the needed functions.
9634 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9637 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9639 *) Merge multiple headers from CGI scripts instead of taking last
9640 one. [David Robinson]
9642 *) Add support for SCO 5. [Ben Laurie]
9644 Changes with Apache 1.0.1
9646 *) Silence mod_log_referer and mod_log_agent if not configured
9649 *) Recursive includes can occur if the client supplies PATH_INFO data
9650 and the server provider uses relative links; as file.html
9651 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9653 *) The replacement for initgroups() did not call {set,end}grent(). This
9654 had two implications: if anything else used getgrent(), then
9655 initgroups() would fail, and it was consuming a file descriptor.
9658 *) On heavily loaded servers it was possible for the scoreboard to get
9659 out of sync with reality, as a result of a race condition.
9660 The observed symptoms are far more Apaches running than should
9661 be, and heavy system loads, generally followed by catastrophic
9662 system failure. [Ben Laurie]
9664 *) Fix typo in license. [David Robinson]
9666 Changes with Apache 1.0.0 23 Nov 1995
9668 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9670 Changes with Apache 0.8.16 05 Nov 1995
9672 *) New man page for 'httpd' added to support directory [David Robinson]
9674 *) .htgroup files can have more than one line giving members for a
9675 given group (each must have the group name in front), for NCSA
9676 back-compatibility [Robert Thau]
9678 *) Mutual exclusion around accept() is on by default for SVR4 systems
9679 generally, since they generally can't handle multiple processes in
9680 accept() on the same socket. This should cure flaky behavior on
9681 a lot of those systems. [David Robinson]
9683 *) AddType, AddEncoding, and AddLanguage directives take multiple
9684 extensions on a single command line [David Robinson]
9686 *) UserDir can be disabled for a given virtual host by saying
9687 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9688 that this didn't work. [David Robinson]
9690 *) Compiles on QNX [Ben Laurie]
9692 *) Corrected parsing of ctime time format [David Robinson]
9694 *) httpd does a perror() before exiting if it can't log its pid
9695 to the PidFile, to make diagnosing the error a bit easier.
9698 *) <!--#include file="..."--> can no longer include files in the
9699 parent directory, for NCSA back-compatibility. [David Robinson]
9701 *) '~' is *not* escaped in URIs generated for directory listings
9704 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9706 *) Fixed bug involving handling URIs with escaped %-characters
9707 in redirects [David Robinson]
9709 Changes with Apache 0.8.15 14 Oct 1995
9711 *) Switched to new, simpler license
9713 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9715 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9717 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9719 *) Correctly handles internal redirects to files with names containing '%'
9722 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9724 *) Use geteuid() rather than getuid() to see if we have root privilege,
9725 so that server correctly resets privilege if run setuid root. [Andrew
9728 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9731 *) Fix relative URLs in imagemap files [Randy Terbush]
9733 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9736 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9737 entries all name the same one. [David Robinson]
9739 *) Fix directory listings with filenames containing unusual characters
9742 *) Better URI-escaping for generated URIs in directories with filenames
9743 containing unusual characters [Ben Laurie]
9745 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9747 *) Unblock alarms on error return from spawn_child() [David Robinson]
9749 *) Sample Config files have extra note for SCO users [Ben Laurie]
9751 *) Configuration has note for HP-UX users [Rob Hartill]
9753 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9755 *) Nuked bogus #define in httpd.h [David Robinson]
9757 *) Better test for whether a system has setrlimit() [David Robinson]
9759 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9761 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9764 Changes with Apache 0.8.14 19 Sep 1995
9766 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9768 *) AddDescription works (better) [Ben Laurie]
9770 *) Leaves an intelligible error diagnostic when it can't set group
9771 privileges on standalone startup [Andrew Wilson]
9773 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9774 that machine, which claims to be BSD but does not support RLIMIT.
9777 *) gcc -Wall no longer complains about an unused variable when util.c
9778 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9780 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9782 Changes with Apache 0.8.13 07 Sep 1995
9784 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9786 *) Have built-in imagemap code recognize & honor Point directive [James
9789 *) Generate cleaner directory listings in directories with a mix of
9790 long and short filenames [Rob Hartill]
9792 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9794 *) Properly default ServerName for virtual servers [Robert Thau]
9796 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9797 Paul Richards and a cast of thousands...]
9799 *) On self-identified BSD systems (we don't try to guess any more),
9800 allocate a few extra file descriptors per virtual host with setrlimit,
9801 if we can, to avoid running out. [Randy Terbush]
9803 *) Write 22-character lock file name into buffer with enough space
9804 on startup [Konstantin Olchanski]
9806 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9809 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9811 *) Suppress -Wall warning by initializing variable in negotiation code
9812 [Tobias Weingartner]
9814 Changes with Apache 0.8.12 31 Aug 1995
9816 *) Doesn't pause three seconds after including a CGI script which is
9817 too slow to die off (this is done by not even trying to kill off
9818 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9819 after the entire document has been processed). [Robert Thau]
9821 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9823 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9825 *) Allows .htaccess files to override <Directory> sections naming the
9826 same directory [David Robinson]
9828 *) Removed an efficiency hack in sub_req_lookup_uri which was
9829 causing certain extremely marginal cases (e.g., ScriptAlias of a
9830 *particular* index.html file) to fail. [David Robinson]
9832 *) Doesn't log an error when the requested URI requires
9833 authentication, but no auth header line was supplied by the
9834 client; this is a normal condition (the client doesn't no auth is
9835 needed here yet). [Robert Thau]
9837 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9839 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9841 *) RFC931 code no longer passes out name of prior clients on current
9842 requests if the current request came from a server that doesn't
9843 do RFC931. [David Robinson]
9845 *) Configuration script accepts "Module" lines with trailing whitespace.
9848 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9850 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9852 Changes with Apache 0.8.11 24 Aug 1995
9854 *) Wildcard <Directory> specifications work. [Robert Thau]
9856 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9858 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9859 the file being requested itself, in addition to the directories leading
9860 up to it. [Robert Thau]
9862 *) Logs access failures due to symlink checks or invalid client address
9863 in the error log [Roy Fielding, Robert Thau]
9865 *) Symlink checks deal correctly with systems where lstat of
9866 "/path/to/some/link/" follows the link. [Thau, Fielding]
9868 *) Doesn't reset DirectoryIndex to 'index.html' when
9869 other directory options are set in a .htaccess file. [Robert Thau]
9871 *) Clarified init code and nuked bogus warning in mod_access.c
9874 *) Corrected several directives in sample srm.conf
9875 --- includes corrections to directory indexing icon-related directives
9876 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9877 icons for encodings right, and turning on AddEncoding by default).
9880 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9883 *) INSTALL & README mention "contributed modules" directory [Brian
9886 *) Fixed English in the license language... "for for" --> "for".
9889 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9890 mod_alias.c, merging it almost completely with handling of Alias, and
9891 adding a 'notes' field to the request_rec which allows the CGI module
9892 to discover whether the Alias module has put this request through
9893 ScriptAlias (which it needs to know for back-compatibility, as the old
9894 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9897 Changes with Apache 0.8.10 18 Aug 1995
9899 *) AllowOverride applies to the named directory, and not just
9900 subdirectories. [David Robinson]
9902 *) Do locking for accept() exclusion (on systems that need it)
9903 using a special file created for the purpose in /usr/tmp, and
9904 not the error log; using the error log causes real problems
9905 if it's NFS-mounted; this is known to be the cause of a whole
9906 lot of "server hang" problems with Solaris. [David Robinson;
9907 thanks to Merten Schumann for help diagnosing the problem].
9909 Changes with Apache 0.8.9 12 Aug 1995
9911 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9913 *) Nested includes see environment variables of the including document,
9914 for NCSA bug-compatibility (some sites have standard footer includes
9915 which try to print out the last-modified date). [Eric Hagberg/Robert
9918 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9919 URI as a CGI script, even if it would have been treated as something
9920 else if requested directly, for NCSA back-compatibility. (Note that
9921 this means that people who know the name of the script can see the
9922 code just by asking for it). [Robert Thau]
9924 *) New version of dbmmanage script included in support directory as
9927 *) Check if scoreboard file couldn't be opened, and say so, rather
9928 then going insane [David Robinson]
9930 *) POST to CGI works on A/UX [Jim Jagielski]
9932 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9934 *) NCSA server push works properly --- the Arena bug compatibility
9935 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9936 if you still want the workaround). [Rob Hartill]
9938 *) If client didn't submit any Accept-encodings, ignore encodings in
9939 content negotiation. (NB this will all have to be reworked anyway
9940 for the new HTTP draft). [Florent Guillaume]
9942 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9944 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9946 *) Give Redirect priority over Alias, for NCSA bug compatibility
9949 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9950 paralleling earlier bug fix for CGI [David Robinson]
9952 *) If DBM auth is improperly configured, report a server error and don't
9955 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9956 it seems to work well enough without it (even in a 10 hits/sec
9957 workout), and the overhead for the locking under A/UX is
9958 alarmingly high (though it is very low on other systems).
9959 [Eric Hagberg, Jim Jagielski]
9961 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9963 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9964 Behlendorf/Eric Hagberg]
9966 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9968 *) Compiles clean on NEXT [Rob Hartill]
9970 *) Compiles clean on SGI [Robert Thau]
9972 Changes with Apache 0.8.8 08 Aug 1995
9974 *) SunOS library prototypes now never included unless explicitly
9975 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9976 people using GNU libc on SunOS are screwed by prototypes for the
9979 (Those who wish to compile clean with gcc -Wall on a standard
9980 SunOS setup need the prototypes, and may obtain them using
9981 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9982 with nonstandard libraries are presumably competent to make their
9985 *) Strips trailing '/' characters off both args to the Alias command,
9986 to make 'Alias /foo/ /bar/' work.
9988 Changes with Apache 0.8.7 03 Aug 1995
9990 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9991 [reported by David Robinson]
9993 *) Compiles clean on OSF/1 [David Robinson]
9995 *) Added some of the more recent significant changes (AddLanguage stuff,
9996 experimental LogFormat support) to CHANGES file in distribution root
9999 Changes with Apache 0.8.6 02 Aug 1995
10001 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
10002 (If you actually wanted a conditional GET which bypassed the cache, you
10003 couldn't get it). [Reported by Roy Fielding]
10005 *) Properly terminate headers on '304 Not Modified' replies to conditional
10006 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10007 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10009 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10011 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10012 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10013 and older versions don't set the __SUNPRO_C preprocessor variable). On
10014 all other systems, these are never used anyway. [Reported by Mark Cox].
10016 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10018 Changes with Apache 0.8.5 01 Aug 1995
10020 *) Added last-minute configurable log experiment, as optional module
10022 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10023 properly. (One-line fix to http_protocol.c).
10025 *) Work around bogus behavior when reloading from Netscape.
10026 It's Netscape's bug --- for some reason they expect a request with
10027 If-modified-since: to not function as a conditional GET if it also
10028 comes with Pragma: no-cache, which is way out of line with the HTTP
10029 spec (according to Roy Fielding, the redactor).
10031 *) Added parameter to set maximum number of server processes.
10033 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10036 *) IdentityCheck bugfix [Chuck Murcko].
10038 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10040 *) More sample config file corrections; add extension to AddType for
10041 *.asis, move AddType generic description to its proper place, and
10042 fix miscellaneous typos. [ Alexei Kosut ]
10044 *) Deleted the *other* reference to the regents from the Berkeley
10045 legal disclaimer (everyplace).
10047 *) Nuked Shambhala name from src/README; had already cleaned it out
10048 of everywhere else.
10050 Changes with Apache 0.8.4
10052 *) Changes to server-pool management parms --- renamed current
10053 StartServers to MinSpareServers, created separate StartServers
10054 parameter which means what it says, and renamed MaxServers to
10055 MaxSpareServers (though the old name still works, for NCSA 1.4
10056 back-compatibility). The old names were generally regarded as
10057 too confusing. Also altered "docs" in sample config files.
10059 *) More improvements to default config files ---
10060 sample directives (commented out) for XBitHack, BindAddress,
10061 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10062 defaults, AddTypes for send-as-is and imagemap magic types, and
10063 improvements to samples for DirectoryIndex [Alexei Kosut]
10065 *) Yet more improvements to default config files --- changes to
10066 Alexei's sample AddLanguage directives, and sample LanguagePriority
10067 [ Florent Guillaume ]
10069 *) Set config file locations properly if not set in httpd.conf
10072 *) Don't escape URIs in internal redirects multiple times; don't
10073 do that when translating PATH_INFO to PATH_TRANSLATED either.
10076 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10078 Changes with Apache 0.8.3
10080 *) Edited distribution README to *briefly* summarize installation
10081 procedures, and give a pointer to the INSTALL file in the src/
10084 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10085 recent NCSA distributions.
10087 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10088 exist for the same directory, use both and don't segfault. [Reported
10091 *) Proper makefile dependencies [David Robinson]
10093 *) Note (re)starts in error log --- reported by Rob Hartill.
10095 *) Only call no2slash() after get_path_info() has been done, to
10096 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10097 reported by Andrew Wilson, though this one is probably a real bug]
10099 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10100 dump core when Referer is not supplied. [Randy Terbush]
10102 *) Lightly edited sample config files to refer people to our documentation
10103 instead of NCSA's, and to list Rob McCool as *original* author (also
10104 deleted his old, and no doubt non-functional email address). Would be
10105 nice to have examples of new features...
10107 Changes with Apache 0.8.2 19 Jul 1995
10109 *) Added AddLanuage code [Florent Guillaume]
10111 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10113 *) All sorts of problems when MultiViews finds a directory. It would
10114 be nice if mod_dir.c was robust enough to handle that, but for now,
10115 just punt. [reported by Brian Behlendorf]
10117 *) Wait for all children on restart, to make sure that the old socket
10118 is gone and we can reopen it. [reported by Randy Terbush]
10120 *) Imagemap module is enabled in default Configuration
10122 *) RefererLog and UserAgentLog modules properly default the logfile
10125 *) Mark Cox's mod_cookies added to the distribution as an optional
10126 module (commented out in the default Configuration, and noted as
10127 an experiment, along with mod_dld). [Mark Cox]
10129 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10131 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10133 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10135 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10138 Changes with Apache 0.8.1
10140 *) New imagemap module [Randy Terbush]
10142 *) Replacement referer log module with NCSA-compatible RefererIgnore
10143 [Matthew Gray again]
10145 *) Don't mung directory listings with very long filenames.
10146 [Florent Guillaume]
10148 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10150 *) New config script. See INSTALL for info. [Robert Thau]
10152 *) Scoreboard mechanism for regulating the number of extant server
10153 processes. MaxServers and StartServers defaults are the same as
10154 for NCSA, but the meanings are slightly different. (Actually,
10155 I should probably lower the MaxServers default to 10).
10157 Before asking for a new connection, each server process checks
10158 the number of other servers which are also waiting for a
10159 connection. If there are more than MaxServers, it quietly dies
10160 off. Conversely, every second, the root, or caretaker, process
10161 looks to see how many servers are waiting for a new connection;
10162 if there are fewer than StartServers, it starts a new one. This
10163 does not depend on the number of server processes already extant.
10164 The accounting is arranged through a "scoreboard" file, named
10165 /tmp/htstatus.*, on which each process has an independent file
10166 descriptor (they need to seek without interference).
10168 The end effect is that MaxServers is the maximum number of
10169 servers on an *inactive* server machine, but more will be forked
10170 off to handle unusually heavy loads (or unusually slow clients);
10171 these will die off when they are no longer needed --- without
10172 reverting to the overhead of full forking operation. There is a
10173 hard maximum of 150 server processes compiled in, largely to
10174 avoid forking out of control and dragging the machine down.
10175 (This is arguably too high).
10177 In my server endurance tests, this mechanism did not appear to
10178 impose any significant overhead, even after I forced it to put the
10179 scoreboard file on a normal filesystem (which might have more
10180 overhead than tmpfs). [Robert Thau]
10182 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10185 *) Read .htaccess files even in directory with <Directory> section.
10186 (Former incompatibility noted on mailing list, now fixed). [Robert
10189 *) "HEAD /" gives the client a "Bad Request" error message, rather
10190 than trying to send no body *and* no headers. [Cliff Skolnick].
10192 *) Don't produce double error reports for some very obscure cases
10193 mainly involving auth configuration (the "all modules decline to
10194 handle" case which is a sure sign of a server bug in most cases,
10195 but also happens when authentication is badly misconfigured).
10198 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10199 it's *for*, and this sort of thing really shouldn't be cluttering
10200 up the Makefile). [Robert Thau]
10202 *) Incidental code cleanups in http_main.c --- stop dragging
10203 sa_client around; just declare it where used. [Robert Thau]
10205 *) Another acc-related fix. (It doesn't like const char
10206 in some places...). [Mark Cox]
10208 Changes with Shambhala 0.6.1 13 Jul 1995
10210 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10211 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10213 *) Compiles clean with acc on SunOS [Paul Sutton]
10215 *) Reordered modules in modules.c so that Redirect takes priority
10216 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10217 believe it or not, he has an actual site with a ScriptAlias and
10218 a Redirect declared for the *exact same directory*. Even *my*
10219 compatibility fetish wouldn't motivate me to fix this if the fix
10220 required any effort, but it doesn't, so what the hey.
10222 *) Fixed to properly default several server_rec fields for virtual
10223 servers from the corresponding fields in the main server_rec.
10224 [Cliff Skolnick --- 'port' was a particular irritant].
10226 *) No longer kills off nph- child processes before they are
10227 finished sending output. [Matthew Gray]
10229 Changes with Shambhala 0.6.0 10 Jul 1995
10231 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10232 the connection to the client in an "aborted" state, but otherwise
10233 allow whatever handlers are running to clean up. hard_timeout()s
10234 abort the request in progress completely; anything not tied to some
10235 resource pool cleanup will leak. They're still around because I
10236 haven't yet come up with a more elegant way of handling
10237 timeouts when talking to something that isn't the client. The
10238 default_handler and the dir_handler now use soft timeouts, largely
10239 so I can test the feature. [Robert Thau]
10241 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10242 the case of log handlers dying prematurely is probably handled VERY
10243 gracelessly at this point, and if the logger stops reading input,
10244 the server will hang. (It is known to correctly restart the
10245 logging process on server restart; this is (should be!) going through
10246 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10247 script). [Robert Thau]
10249 *) asis files supported (new module). [Robert Thau]
10251 *) IdentityCheck code is compiled in, but has not been tested. (I
10252 don't know anyone who runs identd). [Robert Thau]
10254 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10255 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10257 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10259 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10260 as timeouts are not in scope. [Robert Thau]
10262 *) quoted-string args in config files now handled correctly (doesn't drop
10263 the last character). [Robert Thau; reported by Randy Terbush]
10265 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10266 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10268 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10269 default default type); the former default default behavior when all
10270 type-checkers defaulted had been a core dump. [Paul Sutton]
10272 *) Copy filenames out of the struct dirent when indexing
10273 directories. (On Linux, readdir() returns a pointer to the same
10274 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10276 Changes with Shambhala 0.5.3 [not released]
10278 *) Default response handler notes "file not found" in the error log,
10279 if the file was not found. [Cliff Skolnick].
10281 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10282 code no longer sets up bogus PATH_INFO which fakes out the directory
10283 handler). [Cliff Skolnick]
10285 Changes with Shambhala 0.5.2 06 Jul 1995
10287 *) Changes to http_main.c --- root server no longer plays silly
10288 games with SIGCHLD, and so now detects and replaces dying
10289 children. Child processes just die on SIGTERM, without taking
10290 the whole process group with them. Potential problem --- if any
10291 child process refuses to die, we hang in restart.
10292 MaxRequestsPerChild may still not work, but it certainly works
10293 better than it did before this! [Robert Thau]
10295 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10296 work (or work better, at least); over-long description lines
10297 properly terminated. [Mark Cox]
10299 *) http_request.c now calls unescape_url() more places where it
10300 should [Paul Sutton].
10302 *) More directory handling bugs (reported by Cox)
10303 Parent Directory link is now set correctly. [Robert Thau]
10305 Changes with Shambhala 0.5.1 04 Jul 1995
10307 *) Generalized cleanup interface in alloc.c --- any function can be
10308 registered with alloc.c as a cleanup for a resource pool;
10309 tracking of files and file descriptors has been reimplemented in
10310 terms of this interface, so I can give it some sort of a test.
10313 *) More changes in alloc.c --- new cleanup_for_exec() function,
10314 which tracks down and closes all file descriptors which have been
10315 registered with the alloc.c machinery before the server exec()s a
10316 child process for CGI or <!--#exec-->. CGI children now get
10317 started with exactly three file descriptors open. Hopefully,
10318 this cures the problem Rob H. was having with overly persistent
10319 CGI connections. [Robert Thau]
10321 *) Mutual exclusion around the accept() in child_main() --- this is
10322 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10323 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10324 This uses fcntl(F_SETLK,...) on the error log descriptor because
10325 flock() on that descriptor won't work on systems which have BSD
10326 flock() semantics, including (I think) Linux 1.3 and Solaris.
10328 This does work on SunOS (when the server is idle, only one
10329 process in the pool is waiting on accept()); it *ought* to work
10330 on the other systems. [Robert Thau]
10332 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10334 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10336 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10338 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10339 be unnecessary if I go to the revised timeout-handling scheme).
10342 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10343 string) even if none came in with the request. [Robert Thau]
10345 *) CHANGES file added to distribution ;-).
10347 Changes with Shambhala 0.4.5
10349 *) mod_dld --- early dynamic loading support [rst]
10350 *) Add wildcard content handlers for XBITHACK; default_hander now
10351 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10352 *) XBITHACK supported as a wildcard content-handler, and
10353 configurable at run-time (not just at compile time, as in the
10354 "patchy server" releases) [rst]
10356 Changes with Shambhala 0.4.4 30 Jun 1995
10358 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10359 *) Handle Addtype x/y .z [rst, reported by Cox]
10361 Changes with Shambhala 0.4.3
10363 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10364 synonymous [rst, terbush]
10366 Changes with Shambhala 0.4.1 28 Jun 1995
10368 *) First-cut virtual host implementation; some refit in the config
10369 reading code, and log management, was necessary to support this [rst]
10370 *) Sub-pool machinery, originally added to avoid excessive storage
10371 allocation on listings of large directories (which turned out to
10372 be the problem that the 0.3 storage accounting was added to
10373 find). Subrequests and mod_dir changed to use subpools. [rst]
10374 *) More memory debugging --- free list consistency checks. [rst]
10375 *) Added err_headers to request_rec, with support elsewhere [rst]
10376 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10378 Changes with Shambhala 0.3 19 Jun 1995
10380 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10381 *) Don't compile in mod_ai_backcompat by default
10382 *) Switch name of server from Apache to Shambhala in Makefile
10383 *) Add some accounting routines to track memory usage in the pools,
10386 Changes with Shambhala 0.2
10388 *) Set DOCUMENT_ROOT CGI variable
10389 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10390 *) Add critical section protection to handling of cleanup structures
10392 *) Significant code reorg within the server core to group related
10393 functions together [rst]
10394 *) Correctly handle clients that hang up before sending any request
10396 *) Replace dying child processes. [rst]
10398 Changes with Shambhala 0.1 12 Jun 1995
10400 Major rewrite of the pre-existing "patchy server" codebase, by
10401 Robert Thau (rst). Significant portions of the server code, such
10402 as configuration-file handling and HTTP authentication support,
10403 were ripped out and rewritten from scratch. Code that was not
10404 completely rewritten was significantly altered.
10406 Major changes with this release include:
10408 *) Introduction of the module API; in request handling, the central
10409 machinery just dispatches to various modules, which actually do
10410 most of the work. Configuration handling is similar --- modules
10411 declare their own commands, and the central machinery just
10412 dispatches to them.
10414 API features from shambhala/0.1 were substantially unchanged in
10415 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10416 release, such as wildcard handlers and subpools, were added in
10417 subsequent Shambhala releases, and were also generally rst's
10420 *) This release included the following modules:
10422 mod_access (access control --- allow and deny directives),
10423 mod_alias (Alias and Redirect commands),
10424 mod_auth (straight HTTP authentication, based on flat-files)
10425 mod_auth_dbm (same, with dbm files)
10426 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10427 mod_common_log (CLF access logs; later renamed mod_log_common)
10428 mod_dir (directory indexing)
10429 mod_include (server-side includes)
10430 mod_mime (AddType directives)
10431 mod_negotiation (content negotiation)
10432 mod_userdir (support for users' public_html directories)
10434 It also included a mod_ai_backcompat, which was a private hack
10435 for back-compatibility with rst's own AI-lab servers.
10437 All of these modules were substantially complete, and functional
10438 or nearly so (a few, which implemented features not in use at
10439 Thau's site, required patches of a few lines).
10441 *) sub-request machinery, to allow modules to determine how other
10442 modules would assign MIME types to a given file, or optionally
10443 serve its content (this is heavily used by mod_dir, mod_include
10444 and mod_negotiation).
10446 *) Resource pool system for keeping track of memory allocated and
10447 files opened in service of a particular request. Much of the
10448 code in the modules (when they weren't rewrites) was adjusted to
10449 replace a pervasive convention of using fixed-size buffers on
10450 the stack with an equally pervasive convention of using memory
10451 allocated with palloc().
10453 *) Reorganization of data structures associated with a given
10454 request to eliminate use of global variables and the troublesome
10455 unmunge_name function (used in NCSA and early Apache releases to
10456 attempt to determine the URI which mapped to a given filename
10457 --- a difficult proposition, given that it is easy to produce
10458 setups in which multiple URIs map to the same file).
10460 *) Source files renamed and rearranged
10462 *) Very simple pre-forking behavior --- parent process forked off a
10463 fixed number of children, and then just waited for SIGHUP.
10465 *) Other more minor changes too numerous to list.
10467 This release included modified versions of a lot of code from the
10468 Apache 0.6.4 public release, plus an early pre-forking patch
10469 codeveloped by Robert Thau and Rob Hartill.
10471 Changes with Apache 0.7.3 20 Jun 1995
10473 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10474 were incorporated by Rob Hartill on the main branch while Robert Thau
10475 worked on the Shambhala rewrite above. Most were merged into the
10476 Shambala architecture after Apache 0.8.0.
10478 Changes with Apache 0.6.4 13 May 1995
10480 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10483 Changes with Apache 0.5.1 10 Apr 1995
10485 Changes with Apache 0.4 02 Apr 1995
10487 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10490 Changes with Apache 0.3 24 Mar 1995
10492 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10495 Changes with Apache 0.2 18 Mar 1995
10497 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10498 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10499 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
