1 Changes with Apache 2.0.29-dev
3 *) Add Debian layout. [Daniel Stone <daniel@sfarc.net>]
5 *) If shared modules are requested and mod_so is not available,
6 produce a fatal config-time error. [Justin Erenkrantz]
8 *) Improve http2env's performance by cutting the work it has to
9 do. [Brian Pane <bpane@pacbell.net>]
11 *) use new 'apr_hash_merge' function in mod_mime (performance fix)
12 [Brian Pane <bpane@pacbell.net>]
14 Changes with Apache 2.0.28
16 *) When no port is given in a "ServerName host" directive, the
17 server_rec->port is now set to zero, not 80. That allows for
18 run-time deduction of the correct server port (depending on
19 SSL/plain, and depending also on the current setting of
20 UseCanonicalName). This change makes redirections
21 work, even with https:// connections. As in Apache-1.3, the
22 connection's actual port number is never used, only the ServerName
23 setting or the client's Host: setting. Documentation updated
24 to reflect the change. [Martin Kraemer]
26 *) Add a '%{note-name}e' argument to mod-headers, which works in
27 the same way as mod_log_confg. [Ian Holsman]
29 *) Fix the spelling of the AP_MPMQ_MIN_SPARE_DAEMONS and
30 AP_MPMQ_MAX_REQUESTS_DAEMON macros in ap_mpm.h and all standard
33 *) Introduce htdbm, a user management utility for db/dbm authorization
34 databases. [Mladen Turk <mturk@mappingsoft.com>]
36 *) Optimize usage of strlen and strcat in ap_directory_walk.
37 [Brian Pane <bpane@pacbell.net>]
39 Changes with Apache 2.0.27
41 *) Introduce an Apache mod_ssl initial configuration template
42 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
44 *) Fixed a memory leak in the getline parsing code that could
45 be triggered by arbitrarily large header lines. Requests
46 from the core input filter for single lines are now limited
47 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
49 *) Fix a truncation bug in how we print the port on the Via: header.
50 The routine that prints the Via: header now takes a length for
51 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
53 *) Some syntax errors in mod_mime_magic's magic file can result
54 in a 500 error, which previously was unlogged. Now we log the
57 *) Add the support/checkgid helper app, which checks the run-time
58 validity of group identifiers usable in the Group directive.
61 *) Various --enable-so options have been fixed: --enable-so is
62 treated as "static"; explicit --enable-so=shared issues an error;
63 and explicit --enable-so fails with error on systems without
64 APR_HAS_DSO. [Aaron Bannert]
66 *) Fix a segfault in the core input filter when the client socket
67 gets disconnected unexpectedly. [Cliff Woolley]
69 *) Fix the reporting for child processes that die. This removes
70 all of the non-portable W* macros from Apache.
71 [Jeff Trawick and Ryan Bloom]
73 *) Win32: Track and display "Parent Server Generation:" in
74 mod_status output. The generation will be bumped at
75 server graceful restart, when the child process exits
76 by hitting MaxRequestsPerChild or if the child
77 process exits abnormally. [Bill Stoddard]
79 *) Win32: Fix problem where MaxRequestsPerChild directive was
80 not being picked up in favor of the default. Enable
81 the parent to start up a new child process immediately upon
82 the old child starting shutdown.
85 *) Fix some bungling of the remote port in rfc1413.c so that
86 IdentityCheck retrieves the proper user id instead of failing
87 and thus always returning "nobody."
88 [Dick Streefland <Dick.Streefland@xs4all.nl>]
90 *) Introduced thread saftey for mod_rewrite's internal cache.
91 [Brian Pane <bpane@pacbell.net>]
93 *) Simplified mod_env's directives to behave as most directives are
94 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
95 directive following that UnsetEnv within the same container.
96 Also provides a runtime startup warning if a PassEnv configured
97 environment value is undefined. [William Rowe]
99 *) The worker MPM is now completely ported to APR's new lock API. It
100 uses native APR types for thread mutexes, cross-process mutexes,
101 and condition variables. [Aaron Bannert]
103 *) Sync up documentation to remove all references to the now deprecated
104 Port directive. [Justin Erenkrantz]
106 *) Moved all ldap modules from the core to httpd-ldap sub-project
109 *) Exit when we can't listen on any of the configured ports. This
110 is the same behavior as 1.3, and it avoids having the MPMs to
111 deal with bogus ap_listen_rec structures. [Jeff Trawick]
113 *) Cleanup the proxy code that creates a request to the origin
114 server. This change adds an optional hook, which allows modules
115 to gain control while the request is created if the proxy module
116 is loaded. The purpose of this hook is to allow modules to add
117 input and/or output filters to the request to the origin. While
118 I was at it, I made the core use this hook, so that proxy request
119 creation uses some of the code from the core. This can still be
120 greatly improved, but this is a good start. [Ryan Bloom]
122 Changes with Apache 2.0.26
124 *) Port the MaxClients changes from the worker MPM to the threaded
127 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
128 with the new input filtering system. [Justin Erenkrantz]
130 *) Introduce the MultiviewsMatch directive, to allow the operator
131 to be flexible in recognizing Handlers and Filters filename
132 extensions as part of the Multiviews matching logic, strict with
133 MultiviewsMatch NegotiatedOnly to accept only filename extentions
134 that designate negotiated parameters, (content type, charset, etc.)
135 or MultiviewsAll for the 1.3 behavior of matching any files, even
136 if they have unregistered extensions. [William Rowe]
138 *) Fixed the configure script to add a LoadModule directive to
139 the default httpd.conf for any module that was compiled
140 as a DSO. [Aaron Bannert <aaron@clove.org>]
142 *) rewrite mod_ssl input filtering to work with the new input filtering
143 system. [Justin Erenkrantz]
145 *) prefork: Don't segfault when we are able to listen on some but
146 not all of the configured ports. [Jeff Trawick]
148 *) Build mod_so even if no core modules are built shared.
149 [Aaron Bannert <aaron@clove.org>]
151 *) Introduce ap_directory_walk rewrite (with further optimizations
152 required) to adapt to the ap_process_request_internal() changes.
153 Optimized so subrequests and redirects now reuse previous section
154 merges, until we mismatch with the original directory_walk, and
155 precomputed r->finfo results will cause directory_walk to skip
156 the most expensive phases of the function. [William Rowe]
158 *) Allow ApacheMonitor to connect to and control Apache on other
159 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
161 *) Remove the Port directive. In it's place, the Listen directive
162 is now a required directive, which tells Apache what port to
163 listen on. The ServerName directive has also been extended
164 to accept an optional port. If the port is specified to the
165 ServerName, the server will report that port whenever it
166 reports the port that it is listening on. This change was
167 made to ease configuration errors that stem from having a Port
168 directive, and a Listen directive. In that situation, the server
169 would only listen to the port specified by the Listen command,
170 which caused a lot of confusion to users. [Ryan Bloom]
172 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
173 build, as loadable modules. [William Rowe]
175 *) Fix --enable-mods-shared processing. If most is specified,
176 then all modules that can be compiled as shared modules are.
177 [Aaron Bannert <aaron@clove.org>]
179 *) Update the mime.types file to map video/vnd.mpegurl to mxu
180 and add commonly used audio/x-mpegurl for m3u extensions.
181 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
183 *) Eliminate the depreciated r->content_language, in favor of the array
184 r->content_languages introduced many years ago. Module authors must
185 substantially overhaul their modules, so this needs to be upgraded
186 if the module still relied on backwards-brokeness. [William Rowe]
188 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
191 *) Rewrite the input filtering mechanisms to consolidate and reorganize
192 code. In short, core_input_filter does something now and
193 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
195 *) Update the Win32 build to re-absorb mod_proxy and family.
198 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
199 current SDK.) [William Rowe]
201 *) Some style changes to the code that does ProxyErrorOverride. Fixed
202 config merge behaviour. [Graham Leggett]
204 *) Allow support programs to be compiled against a static version
205 of libapr. This allows the smaller support programs to be
206 relocated. [Aaron Bannert <aaron@clove.org>]
208 *) Update the mime.types file to the registered media types as
209 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
211 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
212 number of clients that can connect at the same time, instead of
213 specifying the maximum number of child processes.
214 [Aaron Bannert <aaron@clove.org>]
216 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
217 be consistent with 1.3. [Justin Erenkrantz]
219 *) Cache apr_explode_localtime() value for 15 seconds.
220 [Brian Pane <bpane@pacbell.net>]
222 *) Fix mod_include to not return ETag or Last-Modified headers.
223 [Ian Holsman <ianh@cnet.com>]
225 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
227 *) Eliminate the wasteful run-time conversion of method names from strings
228 to numbers in places where the methods are known at compile time.
229 [Brian Pane <bpane@pacbell.net>]
231 *) Turn the worker MPM's queue into a LIFO. This may
232 improve cache-hit performance under some conditions.
233 [Aaron Bannert <aaron@clove.org>]
235 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
236 support it. [Justin Erenkrantz]
238 *) Cleanup the worker MPM. We no longer re-use transaction
239 pools. This incurs less overhead than shuffling the pools
240 around so that they can be re-used. Remove one of the
241 queue's condition variables. We just redefined the API to
242 state that you can't try to add more stuff than you allocated
243 segments for. [Aaron Bannert <aaron@clove.org>]
245 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
247 *) Fixed persistent connections when a request contains a body.
250 *) mod_dav uses a new API to speak to the backend provider for dead
251 property management. [Greg Stein]
253 *) Remove the Win32 script-processing exception from mod_cgi, and
254 roll build_command_line/build_argv_list into a unified, overrideable
255 ap_cgi_build_command optional function. [William Rowe]
257 *) Rewrite find_start_sequence to use a better search algorithm
258 to find the start tag. [Justin Erenkrantz]
260 *) Fix a seg fault in mod_include. When we are generating an
261 internal redirect, we must set r->uri to "", not a bogus
262 string, and not NULL. [Ryan Bloom]
264 *) Optimized location_walk, so subrequests, redirects and second passes
265 now reuse previous section merges on a <Location > by <Location >
266 basis, until we mismatch with the original location_walk.
269 *) Back out the 1.45 change to util_script.c. This change made
270 us set the environment variable REQUEST_URI to the redirected
271 URI, instead of the originally requested URI.
272 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
274 *) Make mod_include do lazy evaluation of potentially expensive to
275 compute variables. [Brian Pane <bpane@pacbell.net>]
277 *) Fix logging of bytes sent for HEAD requests. %b and %B should
278 log either - or 0, before this patch, they were both logging
279 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
281 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
282 than per character. [Brian Pane <bpane@pacbell.net>]
284 *) Normalize the primary request, redirects and sub-requests to
285 run the same ap_process_request_internal for consistency in
286 robustness, behavior and security. [William Rowe]
288 *) Fix a segfault with mod_include when r->path_info is not set
289 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
291 *) Add -X functionality back. This indicates to all MPMs and any other
292 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
294 *) Some initial support for the cygwin platform [prefork only].
295 This is not to be confused with support for the WinNT/Win32
296 platform, which is the recommended configuration for native
297 Win32 users. The cygwin platform support is recommended for
298 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
300 *) Changed syntax of Set{Input|Output}Filter. The list of filters
301 must be semicolon delimited (if more than one filter is given.)
302 The Set{Input|Output}Filter directive now overrides a parent
303 container's directive (e.g. SetInputFilter in <Directory /web/foo>
304 will override any SetInputFilter directive in <Directory /web>.)
305 This new syntax is more consistent with Add{Input|Output}Filter
306 directives defined in mod_mime. Also cures a bug in prior releases
307 where the Set{Input|Output}Filter directive would corrupt the
308 global configuration if the multiple directives were nested.
311 *) Cured what's ailed mime for quite some time. If an AddSomething
312 was given in the configuration (Language, Charset, Handler or
313 Encoding) Apache would set the content type as given by AddType,
314 but refused to check the mime.types file if AddType wasn't given
315 for that specific extension. Setting the AddHandler for .html
316 without setting the AddType text/html html would cause Apache to
317 use the default content type. [William Rowe]
319 *) Added some bulletproofing to memory allocation in the LDAP cache
320 code. [Graham Leggett]
322 Changes with Apache 2.0.25
324 *) Move the installed /manual directory out of the /htdocs/ tree, so
325 that it can be kept more independently from the remaining document
326 root. The "Alias /manual ..." already allowed for easy projection
327 into existing private document trees. [Martin Kraemer]
329 *) Add specified user attributes to the environment when using
330 mod_auth_ldap. This allows you to use mod_include to embed specified
331 user attributes in a page like so:
332 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
335 *) Fix a performance problem with the worker MPM. We now create
336 transaction pools once, and re-use them for each connection.
337 [Aaron Bannert <aaron@clove.org>]
339 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
340 of a 'handler' or 'filter', so that any filename extension that does
341 not contribute to the negotiated metadata can't be served without
342 an explicit request. E.g., if the .Z extension is associated with
343 an unzip filter, the user request somefile.Z.html, mod_negotiation
344 won't serve it. It can serve somefile.Z.html when somefile.Z is
345 requested, since the .Z extension is explictly requested, if the
346 .html extension is associated with ContentType text/html.
349 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
350 and corresponding AddOutputFilter syntax, to insert one or more
351 filters by mod_mime filename extension processing.
354 *) Fix a growing connection pool in core_output_filter() for
355 keepalive requests. [Jeff Trawick]
357 *) Moved split_and_pass_pretag_buckets back to being a
358 macro at Ryans's request. Removed the return from it
359 by setting and returning a return code instead. Updated
360 the code to check the return code from the macro and
361 do the right thing. [Paul J. Reder]
363 *) Fix a segfault when a numeric value was received for Host:.
366 *) Add a function ap_remove_input_filter. This is to match
367 up with ap_remove_output_filter. [Ryan Bloom]
369 *) Clean up location_walk, so that this step performs a minimum
370 amount of redundant effort (it must be run twice, but it will no
371 longer reparse all <Location > blocks when the request uri
372 hadn't changed.) [William Rowe]
374 *) Eliminate proxy: (and all other 'special') processing from the
375 ap_directory_walk() phase. Modules that want to use special
376 walk logic should refer to the mod_proxy map_to_location example,
377 with it's proxy_walk and proxysection implementation. This makes
378 either directory_walk flavor much more legible, since that phase
379 only runs against real <Directory > blocks.
382 *) Fix a security problem in mod_include which would allow
383 an SSI document to be passed to the client unparsed.
384 [Cliff Woolley, Brian Pane]
386 *) Introduce the map_to_storage hook, which allows modules to bypass
387 the directory_walk and file_walk for non-file requests. TRACE
388 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
389 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
392 *) Add the ability for mod_include to add the INCLUDES filter
393 if the file is configured for the server-parsed handler.
394 This makes the configuration for .shtml files much easier
395 to understand, and allows mod_include to honor Apache 1.3
396 config files. Based on Doug MacEachern's patch to PHP
397 to do the same thing. [Ryan Bloom]
399 *) force OpenSSL to ignore process local-caching and to always
400 get/set/delete sessions using mod_ssl's callbacks
401 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
402 Geoff Thorpe <geoff@geoffthorpe.net>]
404 *) Make the worker MPM shutdown and restart cleanly. This also
405 cleans up some race conditions, and gets the worker using
406 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
408 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
410 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
412 *) Fix for mod_include. Ryan's patch to check error
413 codes put a return in the wrong place. Also, the
414 include handler return code wasn't being checked.
415 I don't like macros with returns, so I converted
416 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
417 [Paul J. Reder <rederpj@raleigh.ibm.com>]
419 *) fix segv in mod_mime if no AddTypes are configured
420 [John Sterling <sterling@covalent.net>]
422 *) Enable ssl client authentication at SSL_accept time
423 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
425 *) Fix a segfault in mod_include when the original request has no
426 associated filename (e.g., we're filtering the error document for
427 a bad URI). [Jeff Trawick]
429 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
431 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
432 of httpd is started and shuts down due to socket conflict. Moving the
433 call to ap_log_pid solves the problem.
435 *) Changed the late-1.3 log_config substitution %c to %X, to log the
436 status of the closed connection, as it conflicts with the far more
437 common, historical ssl logging directive %...{var}c. [William Rowe]
439 *) Added the common error/ tree to the build/install targets
440 (similar to the common icons/ tree) for the multi-language error
441 messages that Lars committed earlier. [William Rowe]
443 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
445 *) Added a default commented-out mod_ldap and mod_auth_ldap
446 configuration to httpd-std.conf and httpd-win.conf
449 *) Added documentation for mod_ldap and mod_auth_ldap.
452 *) Enabled negative caching on attribute comparisons in the LDAP cache.
453 Fixed a problem where the default cache TTL was set in milliseconds
454 not microseconds causing the cache to time out almost immediately.
457 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
458 module code to follow APR. [Graham Leggett]
460 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
461 cleaned up when the connection pool pool is cleaned up.
464 *) Fix a minor issue with Jeff Trawick's mod_include
465 patch. Without this patch, the code will just allocate
466 more bytes in get_combined_directive than are needed.
469 *) Added the LDAP authentication module mod_auth_ldap.
470 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
472 *) Added the LDAP cache and connection pooling module mod_ldap.
473 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
475 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
476 by allowing a module to disable itself if its prerequisites are not
477 met. [Justin Erenkrantz]
479 Changes with Apache 2.0.24
481 *) Fix a couple of issues in mod_include when the tag appeared at
482 offsets near 8192 in the file being parsed. [Jeff Trawick]
484 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
485 reached. [Jeff Trawick]
487 *) Numerous improvements to the Win32 build system. Introduced command line
488 builds without requiring .mak files for MSVC 6.0 and later versions.
489 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
492 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
493 reporting of uninstalled services and other error conditions, and changed the
494 default service name to Apache2. [William Rowe]
496 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
497 compatibility with existing Apache 1.3 Win32 Apache management utilites.
498 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
500 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
501 [William Rowe, Greg Ames]
503 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
504 and RemoveCharset directives. [William Rowe]
506 *) The Unix MPMs other than perchild now allow child server
507 processes to use the accept mutex when starting as root and
508 using SysV sems for the accept mutex. Previously, this
509 combination would lead to fatal errors in the child server
510 processes. perchild can't use SysV sems because of security
511 issues. [Jeff Trawick, Greg Ames]
513 *) Added Win32 revision stamp resources to all http binaries
514 (including modules/ and support/ tools.) PR7322 [William Rowe]
516 *) Fix ap_rvprintf to support more than 4K of data at one time.
517 [Cody Sherr <csherr@covalent.net>]
519 *) We have always used the obsolete/deprecated Netscape syntax
520 for our tracking cookies; now the CookieStyle directive
521 allows the Webmaster to choose the Netscape, RFC2109, or
522 RFC2965 format. The new CookieDomain directive allows the
523 setting of the cookie's Domain= attribute, too. PR #s 5006,
524 5023, 5920, 6140 [Ken Coar]
526 *) Tweak server/Makefile so that the rules for generating exports.c
527 are compatible with make utilities which don't expand wildcards
528 in a dependency list (e.g., OS/390 make, certain levels of GNU
529 make). [Jeff Trawick]
531 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
533 *) Begin to sanitize the MPM configuration directives. Now, all
534 MPMs use the same functions for all common MPM directives. This
535 should make it easier to catch all bugs in these directives once.
536 [Cody Sherr <csherr@covalent.net>]
538 *) Close a major resource leak. Every time we had issued a
539 graceful restart, we leaked a socket descriptor.
542 *) Fix a problem with the new method code. We need to cast
543 the 1 to an apr_int64_t or it will be treated as a 32-bit
544 integer, and it will wrap after being shifted 32 times.
545 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
547 *) Fix a bug in mod_expires. Previous to this patch, if you
548 told mod_expires to add 604800 seconds to the last-modified
549 time, it actually added 604800 usec's to the last-modified time,
550 so that when looking at the response it looked like nothing
551 had been done. The root of the problem was that we always compute
552 time in usec's, but we ask users to input sec's. This means we
553 need to convert to usec's before using those values.
556 *) The worker MPM now handles shutdown and restart requests. It
557 definitely isn't perfect, but we do stop the servers correctly.
558 The biggest problem right now is that SIGHUP causes the server to
559 just die. [Ryan Bloom]
561 Changes with Apache 2.0.23
563 *) Use the prefork MPM by default on Unix. [various]
565 *) Added a systray icon monitor application for Win32.
566 [Mladen Turk <mturk@mappingsoft.com>]
568 *) mod_rewrite: Fix the line ending on some non-Unix systems for
569 messages written to the rewrite log.
570 [Richard Labennett <rlabenn@us.ibm.com>]
572 *) All mod_autoindex query parsing is now quietly quashed with the
573 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
574 still drops the column sort <a href>'s for the column headers, but
575 IgnoreClient is required to ignore these Query options entirely.
578 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
579 to allow the client to select plain, FancyIndexing or HTMLTable
580 formatting, V=[0|1] to inhibit or enable version sorting, and
581 P=pattern to return only specific files. The old Query Arguments
582 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
583 as before), and O=A|D for ordering ascending or descending.
586 *) Fixed an error in mod_include's directive parsing routines which
587 caused #if, #elif, and #else expressions containing backslashes
588 to be improperly evaluated. [Cliff Woolley]
590 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
591 drop the icon column, SuppressRules to drop the <hr> elements,
592 and HTMLTable to create rudimentary HTML table listings (implies
593 FancyIndexing). [William Rowe]
595 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
596 from Apache 1.3.15. This is needed for two reasons, first, given
597 multiple machines within a server farm, ETags and Last-Modified
598 stamps won't correspond from machine to machine, and second, many
599 Unixes don't capture changes to the date or time stamp of existing
600 files, since these don't modify the dirent itself. [William Rowe]
602 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
603 and DirectoryWidth options from Apache 1.3.10.
604 [William Rowe, Ken Coar]
606 *) Eliminated FancyIndexing directive, deprecated early in Apache
607 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
609 *) mod_autoindex now excludes any file names that would result in
610 an error, other than a success or redirect. Also optimized
611 the parent directory, always included except in the URI '/'.
614 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
615 negotiated index pages, and prevent the server from defaulting
616 to an autoindex of the directory. mod_negotiation will now die
617 with a 500 Internal Error if it could match some filenames
618 (e.g. for mod_dir) but none can be served. mod_negotation now
619 refuses to serve any file with an extention that mod_mime doesn't
620 recognize, and wasn't part of the request. [William Rowe]
622 *) Eliminate mod_cgi's handling of .exe files without the .exe file
623 extension. This is already handled by multiviews, if the admin
624 wishes to AddHandler .exe or define a content type handler and
625 associate .exe files with that content type. Multiviews must be
626 enabled to allow these to be served. [William Rowe]
628 *) Speed up the server's response to a spike in incoming workload
629 or restarts by assigning empty scoreboard slots to new processes
630 when they are available. [Greg Ames]
632 *) Add a handler to mod_includes.c. This handler is designed to
633 implement the XbitHack directive. This can't be done with a
634 fixup, because we need to check the content-type, which is
635 only available in the handler phase. [Ryan Bloom]
637 *) Make the includes filter check return codes from filters lower in
638 the filter chain. If a lower level filter returns an error, then
639 the request needs to stop immediately. This allows mod_include to
640 stop parsing data once a lower filter recognizes an error.
643 *) Add the ability to extend the methods that Apache understands
644 and have those methods <limit>able in the httpd.conf. It uses
645 the same bit mask/shifted offset as the original HTTP methods
646 such as M_GET or M_POST, but expands the total bits from an int to
647 an ap_int64_t to handle more bits for new request methods than
648 an int provides. [Cody Sherr <csherr@covalent.net>]
650 *) Fix broken mod_mime behavior in merging its arguments. Possible
651 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
653 *) Solve many mod_ssl porting issues (too many to detail) with
654 help from the whole team, but most notably [Ralf S. Engelschall,
655 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
656 Doug MacEachern, William Rowe, Cliff Woolley]
658 *) More stall fixes for the threaded & worker mpm's.
659 Make mod_status output more accurate. Don't
660 count workers in processes which aren't actively
661 serving requests. [Greg Ames]
663 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
665 *) Add a single listener/multiple worker MPM. This MPM is
666 definately not fully correct, but it allows us to solve many
667 of the problems that exist in the threaded MPM. This is a
668 modified version of the threaded MPM. [Ryan Bloom]
670 *) Improve content generation throughout Apache, providing closer
671 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
672 Transitional specifications. [William Rowe]
674 Changes with Apache 2.0.22
676 *) Fix a problem where the threaded MPM stalls after restarts or
677 segfaults. Also prevent multiple active processes from using
678 the same scoreboard slot. [Greg Ames]
680 *) Apache/Win32 now fills in the service description with Apache's
681 server version string, including loaded and advertised modules.
684 *) Improved support for the Win32 build, to recover gracefully from
685 missing apr or apr-util directories or the awk interpreter,
686 create the proper cgi-bin examples, including a test-cgi.bat, and
687 fix the perl shebang line for printenv.pl, when installing from
688 the build environment. [William Rowe]
690 *) Fix a segfault in threaded.c caused by passing uninitialized
691 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
693 *) Use new APR number conversion functions to reduce CPU consumption
694 when setting the content length, and in mod_log_config.
697 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
698 where HEAD response headers were being repeated twice for
699 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
700 problem in the http_header filter was exposed by the recent rewrite
701 of the content_length filter. [Taketo Kabe, Bill Stoddard]
703 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
704 restarts. A garbage pointer to a vhost's server_rec from the
705 previous generation was being left around under certain
706 conditions. [Greg Ames]
708 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
709 used to appear as '(none', without the closing paren.
710 [Günter Knauf <eflash@gmx.net>]
712 *) Improve the exports generating awk script. In the past, we had
713 work around problems in the awk script by avoiding some #if and
714 #ifdefs. This has bitten us many times in generating the exports.c
715 file. This improvement allows corrects the header file parsing.
716 [Sander Striker <striker@apache.org>]
718 Changes with Apache 2.0.21
720 *) Resolve the Win32 htpasswd bug, where a file that existed would be
721 overwritten, regardless of the -c flag.
722 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
724 *) Introduce connection sub-pools into ab. Truncating the lifetime
725 of these allocations means that ab no longer perpetually grows
726 its working set, running out of memory on large request attempts.
729 *) Make scoreboard creation a hook. This allows management
730 modules to have access to the scoreboard at the time that it is
731 created, and at every restart request.
732 [Cody Sherr <csherr@covalent.net>]
734 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
735 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
736 daemon index actually used in the scoreboard. I also
737 updated the pertinent calls. [Paul J. Reder]
739 *) Win32: Prevent listening sockets from being inherited by
740 the Apache child process, CGI scripts, rotatelog process
741 etc. If the Apache child process segfaults, any processes
742 that the child started are not reaped. Prior to this fix,
743 these processes inherited the listening sockets which sometimes
744 prevented the restarted Apache child process from accepting
745 connections (ie, the server would hang).
748 *) Provide vhost and request strings when ExtendedStatus is on.
751 *) Fix some issues with the pod and prefork: check the pod *after*
752 processing a connection so that a server processing a time-
753 consuming request bails out as soon as practical; when the
754 parent process wakes up a server process via connect(), use an
755 APR timeout on the connect() so that we don't hang for a long
756 time if there aren't server processes around to do accept().
757 [Jeff Trawick, Greg Ames]
759 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
760 spends a lot of time in apr_table_get calls. Using the default
761 httpd.conf, the tables for languages and charsets are somewhat
762 large, so the time spent scanning them on each request is
763 significant. Replacing the tables with hash tables provides
764 a nice speedup. [Brian Pane <bpane@pacbell.net>]
766 *) Add two functions to allow modules to access random parts of the
767 scoreboard. This allows modules compiled for one MPM to access the
768 scoreboard, even if it the server was compiled for another MPM.
769 [Harrie Hazewinkel <harrie@covalent.net>]
771 Changes with Apache 2.0.20
773 *) Fix problem in content-length filter where the filter would
774 buffer all the output from a CGI before sending any bytes
775 down the filter stack to the network. This problem would cause
776 significant memory consumption if the CGIs generated
777 lots of bytes. [Bill Stoddard]
779 *) Get non-blocking CGI pipe reads working with the bucket brigades.
782 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
785 *) Fix a bug in the threaded MPM that would cause it to kill off all
786 workers immediately after starting if the number of workers started
787 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
789 Changes with Apache 2.0.19
791 *) Fix problem with threaded MPM. The problem was that if each child
792 process was busy serving a single long-lived request and the server
793 was sent a graceful restart signal, the server would stop serving
794 requests. This would happen because each child process would wait to
795 die until the last thread was done, and the parent wouldn't spawn any
796 new children until a process died. Now, the parent looks at the fact
797 that the children are dying gracefully, and starts new children.
798 Those new children only start enough threads to compliment the number
799 of threads in the other child process that shares the same spot in
800 the scoreboard. In this way, we make sure to never go over
801 MaxClients. [Ryan Bloom]
803 *) modified mod_negotiation and mod_autoindex to speed up by almost a
804 factor of two on apr_dir_read()-enhanced platforms, such as Win32
805 and OS2, by calling ap_sub_request_lookup_dirent() with the results
806 already provided by apr_dir_read(). [William Rowe]
808 *) mod_file_cache is now more robust to filtering and serves requests
809 slightly more efficiently. [Cliff Woolley]
811 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
812 Module was calling ap_rwrite() followed by ap_rflush() but the
813 served content was not being displayed in the browser. Inspection
814 of the output stream revealed that the first data chunk was
815 missing the trailing CRLF required by the RFC. [Bill Stoddard]
817 *) apxs no longer generates ap_send_http_header() in the example handler
819 *) Fix an ab problem which could cause a divide-by-zero exception
820 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
821 [Ian Holsman <ianh@cnet.com>]
823 *) Solve case-insensitive platforms' confusion about negotiated
824 filenames, allowing files of differnt case to match in choosing
825 the document to serve. [William Rowe]
827 *) Fix brokenness when ThreadsPerChild is higher than the built-in
828 limit. We left ap_threads_per_child at the higher value which
829 led to segfaults when doing certain scoreboard operations.
832 *) Fix seg faults and/or missing output from mod_include. The
833 default_handler was using the subrequest pool for files and
834 MMAPs, even though the associated APR structures typically
835 live longer than the subrequest. [Greg Ames]
837 *) Extend mod_setenvif to support specifying regular expressions
838 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
839 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
840 will cause HAVE_TS to be set if any of the request headers begins
841 with "TS" and has a value that begins with any character in the
842 set [a-z]. [Bill Stoddard]
844 *) httpd children now re-bind themselves to a random CPU on
845 multiprocessor systems on AIX via bindprocessor() in 2.0.
846 [Victor J. Orlikowski]
848 *) Fix htdigest. It would go into a loop in getline when adding
849 a second user. [Bill Stoddard]
851 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
853 *) Automatically generate httpd.exp for AIX.
854 DSOs now work again on AIX in 2.0
855 [Victor J. Orlikowski]
857 *) Add a new request hook, error_log. This phase allows modules
858 to act on the error log string _after_ it has been written
859 to the error log. The goal for this hook is to allow monitoring
860 modules to send the error string to the monitoring agent.
863 *) Modify mod_echo to make it use filters for input and output.
864 [Ryan Morgan <rmorgan@covalent.net>]
866 *) Extend mod_headers to support conditional driven Header
867 add, append and set. Use SetEnvIf to set an envar and conditionally
868 add/append/set headers based on this envar thusly:
870 SetEnvIf TSMyHeader value HAVE_TSMyHeader
871 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
873 If the request contains header "TSMyHeader: value" then header
874 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
877 *) Extend mod_headers to support using format specifiers on Header
878 add, append and set header values. Two format specifiers are supported:
880 %t - reports, in UTC microseconds since the epoch, when the
881 request was received.
883 %D - reports the time, in microseconds, between when the request was
884 received and the response sent.
887 Header add MyHeader "This request served in %D microseconds. %t"
889 results in a header being added to the response that looks like this:
891 MyHeader: This request served in D=5438 microseconds. t=991424704447256
895 *) Fix reset_filter(). We need to be careful how we remove filters.
896 If we set r->output_filters to NULL, we also have to reset the
897 connection's filters. [John Sterling]
899 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
901 *) Add a check to ap_die() to make sure the filter stack is sane and
902 contains the correct basic filters when an error occurs. This fixes
903 a problem where headers are not being sent on error. [John Sterling]
905 *) New Header directive 'echo' option. "Header echo regex" will
906 cause any headers received on the request that match regex to be
907 echoed to (included in) the response headers.
910 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
911 This prevented the inclusion of apr_compat.h. PR #7773
912 [Oleg Broytmann <phd@phd.pp.ru>]
914 *) Moved util_uri to the apr-util library. This required a bunch of
915 apr_name changes for the uri utility functions. [Justin Erenkrantz]
917 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
918 insert_filter phase so that other filters are not bypassed by default.
921 *) Reimplement mod_headers as an output filter. mod_headers can now
922 add custom headers to inbound requests using the RequestHeader directive
923 and to responses using the same old Header directive. [Graham Leggett]
925 Changes with Apache 2.0.18
927 *) Fix command-line processing so that if a bad argument is specified
928 Apache will exit. [Jeff Trawick]
930 *) Change the make targets and rules to be consistent in all of the
931 Apache-owned source trees. [Roy Fielding]
933 *) Fix processing of the TRACE method. Previously we passed bogus
934 parms to form_header_field() and it overlaid some vhost structures,
935 resulting in a segfault in check_hostalias().
936 [Greg Ames, Jeff Trawick]
938 *) Win32: Add support for reliable piped logs. If the logging process
939 goes down, Apache will automatically restart it. This function has
940 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
943 *) Do not start piped log processes during the config file
944 preflight. This change also circumvents a problem on
945 Windows where the rotatelog processes created during preflight
946 was not getting cleaned up properly.
949 *) add "Request Phase Participation" info to mod_info
952 *) Make first phase changes to the scoreboard data structures in
953 preparation for the rewriting of the scoreboard per my posted
954 design notes. [Paul J. Reder]
956 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
957 and apr-util, allow it to be overridden by the configure command-line
958 (default="--silent") and introduce LT_LDFLAGS to replace what we were
959 formerly abusing as LTFLAGS. [Roy Fielding]
961 *) Clean up the reporting of incorrect closing container tags.
962 [Barrie Slaymaker <barries@slaysys.com>]
964 *) Simplify the configure process by moving all libtool stuff to APR
965 and moving hints.m4 inline. [Roy Fielding]
967 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
968 of functions used by mod_proxy for export in the DLL
969 [Ian Holsman <IanH@cnet.com>]
971 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
972 request body from its stdin but no reqest body is being written to
973 the cgi. [Jeff Trawick]
975 *) mod_log_config: %c connection status incorrectly logged
976 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
979 *) Get mod_cern_meta working under Windows
982 *) Create Files, and thus MMAPs, out of the request pool, not the
983 connection pool. This solves a small resource leak that had us
984 not closing files until a connection was closed. In order to do
985 this, at the end of the core_output_filter, we loop through the
986 brigade and convert any data we have into a single HEAP bucket
987 that we know will survive clearing the request_rec.
988 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
991 *) Completely revamp configure so that it preserves the standard make
992 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
993 the configure additions to EXTRA_* variables. Also, allow the user
994 to specify NOTEST_* values for all of the above, which eliminates the
995 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
996 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
997 avoid pointless duplications. Fix the order in which flags are given
998 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
999 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
1000 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
1001 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
1003 *) Get mod_tls to compile/work better on Windows. PR #7612
1004 [Bernhard Schrenk <b.schrenk@improx.com>]
1006 *) Fix shutdown/restart hangs in the threaded MPM.
1007 [Jeff Trawick, Greg Ames, Ryan Bloom]
1009 *) Removed the keptalive boolean from conn_rec because it is now only
1010 used by a single routine and can be replaced by a local variable.
1011 [Greg Stein, Ryan Bloom, Roy Fielding]
1013 *) Patch prefork to put enough of the signal processing back in so that
1014 signals are all handled properly now. The previous patch fixed the
1015 deadlock race condition, but broke the user directed signal handling.
1016 This fixes it to work the way it did before my previous prefork patch
1017 (primarily, SIGTERM is now working).
1019 *) Change how input filters decide how much data is returned to the
1020 higher filter. We used to use a field in the conn_rec, with this
1021 change, we use an argument to ap_get_brigade to determine how much
1022 data is retrieved. [Ryan Bloom]
1024 *) Fix seg fault at start-up introduced by Ryan's change to enable
1025 modules to specify their own logging tags. mod_log_config
1026 registers an optional function, ap_register_log_handler().
1027 ap_register_log_handler() was being called by http_core before
1028 the directive hash table was created. This patch creates the
1029 directive hash table before ap_register_log_handler() is
1030 registered as an optional function.
1031 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1033 *) Add ap_set_int_slot() function
1034 [John K. Sterling <sterling@covalent.net>]
1036 *) Under certain circumstances, Apache did not supply the
1037 right response headers when requiring authentication.
1038 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1039 (This is a port of the change that went into Apache 1.3.19.)
1041 *) Allow modules to specify their own logging tags. This basically
1042 allows a module to tell mod_log_config that when %x is encountered
1043 a specific function should be called. Currently, x can be any single
1044 character. It may be more useful to make this a string at some point.
1047 Changes with Apache 2.0.17
1049 *) If a higher-level filter handles the the byterange aspects of a
1050 request, then the byterange filter should not try to redo the
1051 work. The most common case of this happening, is a byterange
1052 request going through the proxy, and the origin server handles
1053 the byterange request. The proxy should ignore it.
1054 [Graham Leggett <minfrin@sharp.fm>]
1056 *) Changed the threaded mpm to have child_main join to each of the
1057 worker threads to make sure the kids are all gone before child_main
1058 exits after a signal (cleanup from perform_idle_server_maintenance).
1059 This is an extension of Ryans recent commit to make the child_main
1062 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1063 report if their threads are dynamic or static. Finally, this also
1064 implements a new API, ap_show_mpm, which returns the MPM that was
1065 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1067 *) Do not install the binaries from the support directory twice.
1068 [jun-ichiro hagino <itojun@iijlab.net>]
1070 *) The ap_f* functions should flush data to the filter that is passed
1071 in, not the the filter after the one passed in.
1072 [Ryan Morgan <rmorgan@covalent.net>]
1074 *) Make ab work again by changing its native types to apr types and formats.
1075 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1077 *) Move the byterange filter and all of the supporting functions back
1078 to the HTTP module. The byterange filter turned out to be very
1079 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1081 *) Make clean, distclean, and extraclean consistently according to the
1082 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1084 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1085 This may have been causing problems stopping processes in the threaded
1088 *) Fix content-length in mod_negotiation to a long int representation.
1091 *) Remove BindAddress from the default config file.
1092 [giles@nemeton.com.au]
1094 *) Allow module authors to add a module to their Apache build using
1095 --with-module, without re-running buildconf. The syntax is:
1096 --with-module=module_type:/path/to/module.c
1097 The configure script will copy the module.c file to
1098 modules/module_type, and it will be added to the relevant Makefiles.
1099 currently, this only works for static modules. [Ryan Bloom]
1101 *) Changes required to make prefork clean up idle children properly.
1102 There was a window during which a starting worker deadlocks when
1103 an idle cleanup arrives before it completes init. Apache then keeps
1104 trying to cleanup the same deadlocked worker forever (until higher
1105 pids come along, but it still will never reduce below the deadlocked
1106 pid). Thus the number of children would not reduce to the correct
1107 idle level. [Paul J. Reder]
1109 Changes with Apache 2.0.16
1111 *) Change the default installation directory to /usr/local/apache2,
1112 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1114 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1117 *) Get MaxRequestsPerChild working with the Windows MPM.
1120 *) Make generic hooks to work, with mod_generic_hook_import/export
1121 experimental modules. [Ben Laurie, Will Rowe]
1123 *) Fix segfaults for configuration file syntax errors such as
1124 "<Directory>" followed by "</Directory" and
1125 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1127 *) Cleanup the --enable-layout option of configure. This makes
1128 us use a consistent location for the config.layout file, and it
1129 makes configure more portable.
1130 [jun-ichiro hagino <itojun@iijlab.net>]
1132 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1133 csv/gnuplot format, rudimentary ssl support and various other tweaks
1134 to make results more true to what is measured. The upshot of this it
1135 turns out that 'ab' has often underreported the true performance of
1136 apache. Often by a order of magnitude :-) See talk/paper of Sander
1137 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1138 [Dirk-Willem van Gulik]
1140 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1141 storage leak this ensures that some unnecessary pipes are closed.
1144 *) Performance: Add quick_handler hook. This hook is called at the
1145 very beginning of the request processing before location_walk,
1146 translate_name, etc. This hook is useful for URI keyed content
1147 caches like Mike Abbott's Quick Shortcut Cache.
1150 *) top_module global variable renamed to ap_top_module [Perl]
1152 *) Move ap_set_last_modified to the core. This is a potentially
1153 controversial change, because this is kind of HTTP specific. However
1154 many protocols should be able to take advantage of this kind of
1155 information. I expect that headers will need one more layer of
1156 indirection for multi-protocol work, but this is a small step in
1157 the right direction. [Ryan Bloom]
1159 *) Enable mod_status by default. This matches what Apache 1.3 does.
1162 *) Add a ScriptSock directive to the default config file. This is
1163 only enabled when mod_cgid is used.
1164 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1166 Changes with Apache 2.0.15
1168 *) Untangled the buildconf script and eliminated the need for build's
1169 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1170 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1172 *) Win32: Don't accept more connections than we have worker threads
1176 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1177 to fork() new child processes.
1180 *) Fix a major security problem with double-reverse lookup checking.
1181 Previously, a client connecting over IPv4 would not be matched
1182 properly when the server had an IPv6 listening socket. PR #7407
1183 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1185 *) Change the way the beos MPM handles polling to allow it to stop and
1186 restart. Problem was the sockets being polled were being reset by
1187 the select call, so once it had accepted a connection it was no
1188 longer listening on the UDP socket we use for shutdown instructions.
1189 APR needs to be altered, patch on it's way. [David Reid]
1191 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1192 on error exit from ap_getline(). Some other code got upset because
1193 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1195 *) Handle ap_discard_request_body() being called more than once.
1196 [Greg Ames, Jeff Trawick]
1198 *) Get rid of an inadvertent close of file descriptor 2 in
1199 mod_mime_magic. [Greg Ames, Jeff Trawick]
1201 *) Add a hook, create_request. This hook allows modules to modify
1202 a request while it is being created. This hook is called for all
1203 request_rec's, main request, sub request, and internal redirect.
1204 When this hook is called, the the r->main, r->prev, r->next
1205 pointers have been set, so modules can determine what kind of
1206 request this is. [Ryan Bloom]
1208 *) Cleanup the build process a bit more. The Apache configure
1209 script no longer creates its own helper scripts, it just
1211 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1213 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1214 proxy requests. [Graham Leggett]
1216 *) Avoid using sscanf to determine the HTTP protocol number in
1217 the common case because sscanf is a performance hog. From
1218 Mike Abbot's Accelerating Apache patch number 6.
1219 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1221 *) Fix a security exposure in mod_access. Previously when IPv6
1222 listening sockets were used, allow/deny-from-IPv4-address rules
1223 were not evaluated properly (PR #7407). Also, add the ability to
1224 specify IPv6 address strings with optional prefix length on Allow
1225 and Deny. [Jeff Trawick]
1227 *) Enhance rotatelogs so that a UTC offset can be specified, and
1228 the logfile name can be formatted using strftime(3). (Brought
1229 forward from 1.3.) [Ken Coar]
1231 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1232 DuplicateHandle on an IOCompletionPort (a practice which
1233 MS "discourages"). The new model does not rely on associating
1234 the completion port with the listening sockets, thus the
1235 completion port can be completely managed within the child
1236 process. A dedicated thread accepts connections off the network,
1237 then calls PostQueuedCompletionStatus() to wake up worker
1238 threads blocked on the completion port.
1241 *) Bring forward the --suexec-umask option which allows the
1242 builder to preset the umask for suexec processes. [Ken Coar]
1244 *) Add a -V flag to suexec, which causes it to display the
1245 compile-time settings with which it was built. (Only
1246 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1248 *) Mod_include should always unset the content-length if the file is
1249 going to be passed through send_parsed_content. There is no to
1250 determine if the content will change before actually scanning the
1251 entire content. It is far safer to just remove the C-L as long
1252 as we are scanning it. [Ryan Bloom]
1254 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1255 request and not Proxy-Authenticate.
1256 [Graham Leggett <minfrin@sharp.fm>]
1258 Changes with Apache 2.0.14
1260 *) Fix content-length computation. We ONLY compute a content-length if
1261 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1262 or we already have all the data. [Ryan Bloom]
1264 *) Report unbounded containers in the config file. Previously, a typo
1265 in the </container> directive could result in the rest of the config
1266 file being silently ignored, with undesired defaults used.
1269 *) Make the old_write filter use the ap_f* functions for the buffering.
1272 *) Move more code from the http module into the core server. This
1273 is core code, basically the default handler, the default input
1274 and output filters, and all of the core configuration directives.
1275 All of this code is required in order for the server to work, with or
1276 without HTTP. The server is closer to working without the HTTP
1277 module, although there is still more to do. [Ryan Bloom]
1279 *) Fix a number of SGI compile warnings throughout the server. Fix some
1280 bad parameters to apr_bucket_read(). Fix a bad statement in
1281 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1282 consistently; we were mixing apr_time_t and time_t in invalid ways
1283 before. In load_file(), call apr_dso_error() instead of
1284 apr_strerror() so that we get a more specific string on some platforms.
1285 PR #6980 [Jeff Trawick]
1287 *) Allow modules to query the MPM about it's execution profile. This
1288 query API can and should be extended in the future, but for now,
1289 max_daemons, and threading or forking is a very good start.
1290 [Jon Travis <jtravis@covalent.net>]
1292 *) Modify mod_include to send blocks of data no larger than 9k.
1293 Without this, mod_include will wait until the whole file is parsed,
1294 or the first tag is found to send any data to the client.
1295 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1297 *) Fix mod_info, so that <Directory> and <Location> directives are
1298 not displayed twice when displaying the current configuration.
1299 [Ryan Morgan <rmorgan@covalent.net>]
1301 *) Add config directives to override DEFAULT_ERROR_MSG and
1302 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1303 [Dan Rench <drench@xnet.com>]
1305 *) Get mod_info building and loading on Win32. [William Rowe]
1307 *) Begin to move protocol independant functions out of mod_http. The goal
1308 is to have only functions that are HTTP specific in the http directory.
1311 Changes with Apache 2.0.13
1313 *) Don't assume that there will always be multiple calls to the byterange
1314 filter. It is possible that we will need to do byteranges with only
1315 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1317 *) Move the error_bucket definition from the http module to the
1318 core server. Every protocol will need this ability, not just
1321 Changes with Apache 2.0.12
1323 *) Modify mod_file_cache to save pre-formatted strings for
1324 content-length and last-modified headers for performance.
1325 [Mike Abbot <mja@trudge.engr.sgi.com>]
1327 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1328 [Jon Travis <jtravis@covalent.net>]
1330 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1331 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1333 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1334 without ever filling it out. This fixes PR 7271.
1335 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1336 Cliff Woolley <cliffwoolley@yahoo.com>]
1338 *) Add a couple of GCC attribute tags to printf style functions.
1339 [Jon Travis <jtravis@covalent.net>]
1341 *) Add the correct language tag for interoperation with the Taiwanese
1342 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1344 *) Migrate the perchild MPM to use the new apr signal child, and
1345 APR thread functions. [Ryan Bloom]
1347 *) Close one copy of the CGI's stdout before creating the new process.
1348 The CGI will still have stdout, because we have already dup'ed it.
1349 This keeps Apache from waiting forever to send the results of a CGI
1350 process that has forked a long-lived child process.
1351 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1353 *) Remove the rest of the pthreads functions from the threaded MPM.
1354 This requires the APR support for a signal thread that was just
1357 *) Make mod_dir use a fixup for sending a redirect to the browser.
1358 Before this, we were using a handler, which doesn't make much
1359 sense, because the handler wasn't generating any data, it would
1360 either return a redirect error code, or DECLINED. This fits the
1361 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1363 *) Make the threaded MPM use APR threads instead of pthreads.
1366 *) Get mod_tls to the point where it actually appears to work in all cases.
1369 *) implement --enable-modules and --enable-mods-shared for "all" and
1370 "most". [Greg Stein]
1372 *) Move the threaded MPM to use APR locks instead of pthread locks.
1375 *) Rename mpmt_pthread to threaded. This is more in line with the
1376 fact that mpmt_pthread shouldn't be using pthreads directly, and
1377 it is a smaller name that doesn't tie into anything.
1380 *) Rename the module structures so that the exported symbol matches
1381 the file name, and it is easier to automate the installation
1382 process (generating LoadModule directives from the module filenames).
1385 *) Remove the coalesce filter. With the ap_f* functions, this filter
1386 is no longer needed. [Ryan Bloom]
1388 Changes with Apache 2.0.11
1390 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1391 added feature of allowing a uid/gid per child process. If no
1392 uid/gid is specified, then Perchild behaves exactly like dexter.
1395 *) Get perchild building again. [Ryan Bloom]
1397 *) Don't disable threads just because we are using the prefork MPM.
1398 If somebody wants to compile without threads, they must now add
1399 --disable-threads to the configure command line. [Ryan Bloom]
1401 *) Begin to move the calls to update_child_status into common code, so
1402 that each individual MPM does not need to update the scoreboard itself.
1405 *) Allow mod_tls to compile under Unix boxes where openssl has been
1406 installed to the system include files.
1407 [Gomez Henri <new-httpd@slib.fr>]
1409 *) Cleanup the mod_tls configure process. This should remove any need
1410 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1411 configure doesn't check that yet. [Ryan Bloom]
1413 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1414 vital that you read modules/tls/README before attempting to build
1417 *) Fix a potential seg fault on all platforms. David Reid fixed this
1418 on BEOS, but the problem could happen anywhere, so we don't want
1419 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1421 *) Add new LogFormat directive, %D, to log time it takes to serve a
1422 request in microseconds. [Bill Stoddard]
1424 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1425 SetOutputFilter. This corresponds nicely with the other Set
1426 directives, which operate on containers while the Add* directives
1427 tend to work directly on extensions. [Ryan Bloom]
1429 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1430 functions for the buffering so that we don't need to compute
1431 the length of the headers before we actually create the header
1432 buffer. [Ryan Bloom]
1434 *) Allow filters to buffer data using the ap_f* functions. These have
1435 become macros that resolve directly to apr_brigade_*.
1438 *) Get the Unix MPM's to do a graceful restart again. If we are going
1439 to register a cleanup with ap_cleanup_scoreboard, then we have to
1440 kill the cleanup with the same function, and that function can't be
1441 static. [Ryan Bloom]
1443 *) Install all required header files. Without these, it was not
1444 possible to compile some modules outside of the server.
1447 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1448 forward from 1.3 to 2.0, we missed a single line, which broke regex
1449 aliases. [Ryan Bloom]
1451 *) We have a poor abstraction in the protocol. This is a temporary
1452 hack to fix the bug, but it will need to be fixed for real. If
1453 we find an error while sending out a custom error response, we back
1454 up to the first non-OK request and send the data. Then, when we send
1455 the EOS from finalize_request_protocol, we go to the last request,
1456 to ensure that we aren't sending an EOS to a request that has already
1457 received one. Because the data is sent on a different request than
1458 the EOS, the error text never gets sent down the filter stack. This
1459 fixes the problem by finding the last request, and sending the data
1460 with that request. [Ryan Bloom]
1462 *) Make the server status page show the correct restart time, and
1463 thus the proper uptime. [Ryan Bloom]
1465 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1466 should reduce the amount of duplicate code that is required to
1467 create CGI processes.
1468 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1470 *) ap_new_connection() closes the socket and returns NULL if a socket
1471 call fails. Usually this is due to a connection which has been
1472 reset. [Jeff Trawick]
1474 *) Move the Apache version information out of httpd.h and into release.h.
1475 This is in preparation for the first tag with the new tag and release
1476 system. [Ryan Bloom]
1478 *) Begin restructuring scoreboard code to enable adding back in
1479 the ability to use IPC other than shared memory.
1480 Get mod_status working on Windows again. [Bill Stoddard]
1482 *) Make mod_status work with 2.0. This will work for prefork,
1483 mpmt_pthread, and dexter. [Ryan Bloom]
1485 *) Correct a typo in httpd.conf.
1486 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1488 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1490 *) Get the correct IP address if ServerName isn't set and we can't
1491 find a fully-qualified domain name at startup.
1492 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1494 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1496 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1497 'extra' stat's for user/group since they should never occur, and now
1498 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1499 volumes. [William Rowe]
1501 *) Adopt apr features to simplify mod_includes. This changes the
1502 behavior of the USER_NAME variable, unknown uid's are now reported
1503 as USER_NAME="<unknown>" rather than the old user#000 result.
1504 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1506 *) Adopt apr features for simplifing mod_userdir, and accept the new
1507 Win32/OS2 exceptions without hiccuping. [William Rowe]
1509 *) Replace configure --with-optim option by using and saving the
1510 environment variable OPTIM instead. This is needed because configure
1511 options do not support multiple flags separated by spaces.
1514 *) Fix some byterange handling. If we get a byte range that looks like
1515 "-999999" where that is past the end of the file, we should return
1516 a PARTIAL CONTENT status code, and return the whole file as one big
1517 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1519 *) Make the error bucket a real meta-data bucket. This means that the
1520 bucket length is 0, and a read returns NULL data. If one of these
1521 buckets is passed down after the headers are sent, this data will
1522 just be ignored. [Greg Stein]
1524 *) The prefork MPM wasn't killing child processes correctly if a restart
1525 signal was received while the process was serving a request. The child
1526 process would become the equivalent of a second parent process. If
1527 we break out of the accept loop, then we need to do die after cleaning
1528 up after ourselves. [Ryan Bloom]
1530 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1531 restarts. [Ryan Bloom]
1533 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1534 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1535 performing very expensive owner, group and permission lookups
1536 and allows the server to function until these apr_finfo_t fields
1537 are implemented under Win32. [William Rowe]
1539 *) Support for typedsafe optional functions - that is functions exported by
1540 optional modules, which, therefore, may or may not be present, depending
1541 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1542 for sample code. [Ben Laurie]
1544 *) filters can now report an HTTP error to the server. This is done
1545 by sending a brigade where the first bucket is an error_bucket.
1546 This bucket is a simple bucket that stores an HTTP error and
1547 a string. Currently the string is not used, but it may be needed
1548 to output an error log. The http_header_filter will find this
1549 bucket, and output the error text, and then return
1550 AP_FILTER_ERROR, which informs the server that the error web page
1551 has already been sent. [Ryan Bloom]
1553 *) If we get an error, then we should remove all filters except for
1554 those critical to serving a web page. This fixes a bug, where
1555 error pages were going through the byterange filter, even though
1556 that made no sense. [Ryan Bloom]
1558 *) Relax the syntax checking of Host: headers in order to support
1559 iDNS. PR#6635 [Tony Finch]
1561 *) Cleanup the byterange filter to use the apr_brigade_partition
1562 and apr_bucket_copy functions. This removes a lot of very messy
1563 code, and hopefully makes this filter more stable.
1566 *) Remove AddModule and ClearModuleList directives. Both of these
1567 directives were used to ensure that modules could be enabled
1568 in the correct order. That requirement is now gone, because
1569 we use hooks to ensure that modules are in the correct order.
1572 *) When SuExec is specified, we need to add it to the list of
1573 targets to be built. If we don't, then any changes to the
1574 configuration won't affect SuExec, unless 'make suexec' is
1575 specifically run. [Ryan Bloom]
1577 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1578 the APR_XTHREAD argument to open a file for consumption by
1579 parallel threads on win32. [William Rowe]
1581 *) Correct a bug in determining when we follow symlinks. The code
1582 expected a stat -1 result, not an apr_status_t positive error.
1583 Also check if the APR_FINFO_USER fields are valid before we
1584 follow the link. [William Rowe]
1586 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1587 mpm_common.c. These functions are only valid on some platforms,
1588 so they should not be in the main-line code. [Ryan Bloom]
1590 *) Remove ap_chdir_file(). This function is not thread-safe,
1591 and nobody is currently using it. [Ryan Bloom]
1593 *) Do not try to run make depend if there are no .c files in the
1594 current directory, doing so makes `make depend` fail.
1597 *) Update highperformance.conf to work with either prefork or
1598 pthreads mpms. [Greg Ames]
1600 *) Stop checking to see if this is a pipelined request if we know
1601 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1602 This keeps us from making an extra read call when serving a 1.0
1603 request. [Ryan Bloom and Greg Stein]
1605 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1606 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1607 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1609 *) Fix the RFC number mentioned when complaining about a missing
1610 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1612 *) Fix an endless loop in ab which occurred when ab was posting
1613 and the server dropped the connection unexpectedly.
1616 *) Fix a segfault while handling request bodies in ap_http_filter().
1617 This problem has been seen with mod_dav usage as well as with
1618 requests where the body was just being discarded. [Jeff Trawick]
1620 *) Some adjustment on the handling and automatic setting (via
1621 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1622 add the capability to specify flags (NOTEST_CFLAGS and
1623 NOTEST_LDFLAGS) which are used to compile Apache, but
1624 not used during the configuration process. Useful for
1625 flags like "-Werror". [Jim Jagielski]
1627 *) Stop using environment variables to force debug mode or
1628 no detach. We now use the -D command line argument to
1629 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1630 [Greg Stein, Ryan Bloom]
1632 *) Change handlers to use hooks. [Ben Laurie]
1634 *) Stop returning copies of filenames from both apr_file_t and
1635 apr_dir_t. We pstrdup the filenames that we store in the
1636 actual structures, so we don't need to pstrdup the strings again.
1639 *) mod_cgi: Fix some problems where the wrong error value was being
1640 traced. [Jeff Trawick]
1642 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1645 *) Add generic hooks. [Ben Laurie]
1647 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1649 *) Fix a segfault caused by mod_ext_filter when the external filter
1650 program does not exist. [Jeff Trawick]
1652 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1653 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1654 was served through mod_charset_lite (or anything else that would
1655 create a transient bucket in this size range). ap_bucket_make_heap()
1656 silently failed (fixed), transient_setaside() discovered it, but
1657 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1659 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1660 is that some browsers send extra lines at the end of POST requests, and
1661 we don't want to delay sending data back to the user just because the
1662 browser isn't well behaved. [Ryan Bloom]
1664 *) Get SuEXEC working again. We can't send absolute paths to suExec
1665 because it refuses to execute those programs. SuEXEC also wasn't
1666 always recognizing configuration changes made using the autoconf
1669 *) Allow the buildconf process to find the config.m4 files in the correct
1670 order. Basically, we can now name config.m4 files as config\d\d.m4,
1671 and we will sort them correctly when inserting them into the build
1672 process. [Ryan Bloom]
1674 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1675 This also allows mod_cgid to use ap_os_create_priviledged_process,
1676 thus allowing for SuExec execution from mod_cgid. Currently, we do
1677 not support everything that standard SuExec supports, but at least
1678 it works minimally now. [Ryan Bloom]
1680 *) Allow SuExec to be configured from the ./configure command line.
1683 *) Update some of the docs in README and INSTALL to reflect some of
1684 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1686 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1687 need to call sendfile again. This gets us serving large files
1688 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1690 *) Get the support programs building cleanly again.
1691 [Cliff Woolley <cliffwoolley@yahoo.com>]
1693 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1694 current directory logic now backs up over bin/ to determine the
1695 server root from the Apache.exe path.
1697 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1698 loadable modules, dynamic libs are all named libfoo.dll, and the
1699 makefile.win populates the include, lib and libexec directories.
1701 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1702 Apache gets IPv6 listening sockets by default. Additionally, the
1703 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1704 numeric address strings (e.g., "Listen [fe80::1]:8080").
1707 *) Modify the install directory layout. Modules are now installed in
1708 modules/. Shared libraries should be installed in libraries/, but
1709 we don't have any of those on Unix yet. All install directories
1710 are modifyable at configure time. [Ryan Bloom]
1712 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1714 *) Get the functions in server/linked into the server, regardless of
1715 which modules linked into the server. This uses the same hack
1716 for Apache that we use for APR and apr-util to ensure all of the
1717 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1718 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1719 the scripts a bit easier.
1722 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1723 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1725 *) Get all of the auth modules to the point that they will install and
1726 be loadable into the server. Our new build/install mechanism expects
1727 that all modules will have a common name format. The auth modules
1728 didn't use that format, so we didn't install them properly.
1731 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1732 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1734 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1736 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1737 after the end of the response. [Ryan Bloom]
1739 *) Get byterange requests working with responses that do not have a
1740 content-length. Because of the way byterange requests work, we have to
1741 have all of the data before we can actually do the byterange, so we
1742 can compute the content-length in the byterange filter.
1745 *) Get exe CGI's working again on Windows.
1748 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1749 they keep track of whether or not their post config hook has been
1750 called before. Instead of a static variable (which is replaced when
1751 the DSO is loaded a second time), use userdata in the process pool.
1754 Changes with Apache 2.0a9
1756 *) Win32 now requires perl to complete the final install step for users
1757 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1758 and installs the conf, htdocs and htdocs/manual directories.
1761 *) Make mod_include use a hash table to associate directive tags with
1762 functions. This allows modules to implement their own SSI tags easily.
1763 The idea is simple enough, a module can insert it's own tag and function
1764 combination into a hash table provided by mod_include. While mod_include
1765 parses an SSI file, when it encounters a tag in the file, it does a
1766 hash lookup to find the function that implements that tag, and passes
1767 all of the relevant data to the function. That function is then
1768 responsible for processing the tag and handing the remaining data back
1769 to mod_include for further processing.
1770 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1772 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1773 fewer parameters: the local and remote socket addresses were removed
1774 from the parameter list because all required information is available
1775 via the APR socket. [Jeff Trawick]
1777 *) Distribution directory structure reorganized to reflect a
1778 normal source distribution with external install targets.
1781 *) The MPMs that need multiple segments of shared memory now create
1782 two apr_shmem_t variables, one for each shared memory allocation.
1783 the problem is that we can't determine how much memory will be required
1784 for shared memory allocations once we try to allocate more than one
1785 variable. The MM code automatically aligns the shared memory allocations,
1786 so we end up needing to pad the amount of shared memory we want based
1787 on how many variables will be allocated out of the shared memory segment.
1788 It is just easier to create a second apr_shmem_t variable, and two
1789 shmem memory blocks.
1792 *) Cleanup the export list a bit. This creates a single unified list of
1793 functions exported by APR. The export list is generated at configure
1794 time, and that list is then used to generate the exports.c file.
1795 Because of the way the export list is generated, we only export those
1796 functions that are valid on the platform we are building on.
1799 *) Enable logging the cookie with mod_log_config
1800 [Sander van Zoest <sander@covalent.net>]
1802 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1805 *) Added lib/aputil/ as a placeholder for utility functions which are not
1806 specific to the Apache HTTP Server (but do not make sense with APR).
1807 The first utility is "apu_dbm": a set of functions to work with DBM
1808 files. This first version can be compiled for SDBM or GDBM databases.
1811 *) Complete re-write of mod_include. This makes mod_include a filter that
1812 uses buckets directly. This has now served the FAQ correctly.
1813 [Paul Reder <rederpj@raleigh.ibm.com>]
1815 *) Allow modules to specify the first filter in a sub_request when
1816 making the sub_request. This keeps modules from having to change the
1817 output_filter immediately after creating the sub-request, and therefore
1818 skip the sub_req_output_filter. [Ryan Bloom]
1820 *) Update ab to accept URLs with IPv6 literal address strings (in the
1821 format described in RFC 2732), and to build Host header fields in
1822 the same format. This allows IPv6 literal address strings to be
1823 used with ab. This support has been tested against Apache 1.3 with
1824 the KAME patch, but Apache 2.0 does not yet work with this format
1825 of the Host header field. [Jeff Trawick]
1827 *) Accomodate an out-of-space condition in the piped logs and the
1828 rotatelogs.c code, and no longer churn log processes for this
1829 condition. [Victor J. Orlikowski]
1831 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1834 Changes with Apache 2.0a8
1836 *) Add a directive to mod_mime so that filters can be associated with
1840 *) Get multi-views working again. We were setting the path_info
1841 field incorrectly if we couldn't find the specified file.
1844 *) Fix 304 processing. The core should never try to send the headers
1845 down the filter stack. Always, just setup the table in the request
1846 record, and let the header filter convert it to data that is ready
1850 *) More fixes for the proxy. There are still bugs in the proxy code,
1851 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1855 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1858 *) APR: Add new apr_getopt_long function to handle long options.
1859 [B. W. Fitzpatrick <fitz@red-bean.com>]
1861 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1862 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1863 hostname resolution/address string parsing and building
1864 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1865 of one of the apr_sockaddr_t structures for a socket. Change
1866 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1868 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1869 I have proxied pages with it, cleanup will commence soon.
1872 *) Make the proxy work with filters. This isn't perfect, because we
1873 aren't dealing with the headers properly. [Ryan Bloom]
1875 *) Do not send a content-length iff the C-L is 0 and this is a head
1876 request. [Ryan Bloom]
1878 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1879 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1881 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1883 *) Get the default_handler to stop trying to deal with HEAD requests.
1884 The idea is to let the content-length filter compute the C-L before
1885 we try to send the data. If we can get the C-L correctly, then we
1886 should send it in the HEAD response.
1889 *) The Header filter can now determine if a body should be sent based
1890 on r->header_only. The general idea of this is that if we delay
1891 deciding to send the body, then we might be able to compute the
1892 content-length correctly, which will help caching proxies to cache
1893 our data better. Any handler that doesn't want to try to compute
1894 the content-length can just send an EOS bucket without data and
1895 everything will just work.
1898 *) Add the referer to the error log if one is available.
1899 [Markus Gyger <mgyger@itr.ch>]
1901 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1902 change, the root of the configuration tree has been exposed to modules
1904 [Ryan Morgan <rmorgan@covalent.net>]
1906 *) Get the core_output_filter to use the bucket interface directly.
1907 This keeps us from calling the content-length filter multiple times
1908 for a simple static request.
1911 *) We are sending the content-type correctly now.
1912 [Ryan Bloom and Will Rowe]
1914 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1915 a bogus bytes-sent value when the only thing being sent was trailers
1916 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1918 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1919 hints file to determine which platforms define
1920 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1923 *) APR: add apr_get_home_directory() [Jeff Trawick]
1925 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1927 *) Not all platforms have INADDR_NONE defined by default. Apache
1928 used to make this check and define INADDR_NONE if appropriate,
1929 but APR needs the check too, and I suspect other applications will
1930 as well. APR now defines APR_INADDR_NONE, which is always a valid
1931 value on all platforms.
1932 [Branko Èibej <brane@xbc.nu>]
1934 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1935 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1937 *) Relax the syntax checking of Host: headers in order to support
1938 iDNS. PR#6635 [Tony Finch]
1940 *) When reading from file buckets we convert to an MMAP if it makes
1941 sense. This also simplifies the default handler because the
1942 default handler no longer needs to try to create MMAPs.
1945 *) BUFF has been removed from the main server. The BUFF code will remain
1946 in the code until it has been purged from the proxy module as well.
1949 *) Byteranges have been completely re-written to be a filter. This
1950 has been tested, and I believe it is working correctly, but it could
1951 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1952 the output from 1.3, the only difference being that 1.3 includes
1953 a content-length in the response, and this does not.
1956 *) APR read/write functions and bucket read functions now operate
1957 on unsigned integers, instead of signed ones. It doesn't make
1958 any sense to use signed ints, because we return the error codes,
1959 so if we have an error we should report 0 bytes read or written.
1962 *) Always compute the content length, whether it is sent or not.
1963 The reason for this, is that it allows us to correctly report
1964 the bytes_sent when logging the request. This also simplifies
1965 content-length filter a bit, and fixes the actual byte-reporing
1966 code in mod_log_config.c
1969 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1970 it says, because it was only used by EOS and FLUSH buckets. Since
1971 neither of those are required at the end of a brigade, this was
1972 really signifying FLUSH_THE_DATA, but that can be determined better
1973 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1974 buckets now return a length of 0, which is actually the amount of data
1975 read, so they make more sense.
1978 *) Allow the core_output_filter to save some data past the end of a
1979 request. If we get an EOS bucket, we only send the data if it
1980 makes sense to send it. This allows us to pipeline request
1981 responses. As a part of this, we also need to allocate mmap
1982 buckets out of the connection pool, not the request pool. This
1983 allows the mmap to outlive the request.
1986 *) Make blocking and non-blocking bucket reads work correctly for
1987 sockets and pipes. These are the only bucket types that should
1988 have non-blocking reads, because the other bucket types should
1989 ALWAYS be able to return something immediately.
1992 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1993 server, but use Ctrl+Break to initiate a graceful restart
1994 instead of duplicating behavior. [John Sterling]
1996 *) Patch mod_autoindex to set the Last-Modified header based on
1997 the directory's mtime, and add the ETag header. [William Rowe]
1999 *) Merge the 1.3 patch to add support for logging query string in
2000 such a way that "%m %U%q %H" is the same as "%r".
2003 *) Port three log methods from mod_log_config 1.3 to 2.0:
2004 CLF compliant '-' byte count, method and protocol.
2007 *) Add a new LogFormat directive, %c, that will log connection
2008 status at the end of the response as follows:
2009 'X' - connection aborted before the response completed.
2010 '+' - connection may be kept-alive by the server.
2011 '-' - connection will be closed by the server.
2014 *) Expand APR for WinNT to fully accept and return utf-8 encoded
2015 Unicode file names and paths for Win32, and tag the Content-Type
2016 from mod_autoindex to reflect that charset if the the feature
2017 macro APR_HAS_UNICODE_FS is true. [William Rowe]
2019 *) Compute the content length (and add appropriate header field) for
2020 the response when no content length is available and we can't use
2021 chunked encoding. [Jeff Trawick]
2023 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
2024 so that content input filters get dechunked data when using
2025 the default handler. Also removed REQUEST_CHUNKED_PASS.
2028 *) Add mod_ext_filter as an experimental module. This module allows
2029 the administrator to use external programs as filters. Currently,
2030 only filtering of output is supported. [Jeff Trawick]
2032 *) Most Apache functions work on EBCDIC machines again, as protocol
2033 data is now translated (again). [Jeff Trawick]
2035 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2036 the EBCDIC support. They are noops on ASCII machines, so this
2037 type of translation doesn't have to be surrounded by #ifdef
2038 CHARSET_EBCDIC. [Jeff Trawick]
2040 *) Fix mod_include. tag commands work again, and the server will
2041 send the FAQ again. This also allows mod_include to set aside
2042 buckets that include partial buckets.
2043 [Ryan Bloom and David Reid]
2045 *) Add suexec support back. [Manoj Kasichainula]
2047 *) Lingering close now uses the socket directly instead of using
2048 BUFF. This has been tested, but since all we can tell is that it
2049 doesn't fail, this needs to be really hacked on.
2052 *) Allow filters to modify headers and have those headers be sent to
2053 the client. The idea is that we have an http_header filter that
2054 actually sends the headers to the network. This removes the need
2055 for the BUFF to send headers.
2058 *) Charset translation: mod_charset_lite handles translation of
2059 request bodies. Get rid of the xlate version of ap_md5_digest()
2060 since we don't compute digests of filtered (e.g., translated)
2061 response bodies this way anymore. (Note that we don't do it at
2062 all at the present; somebody needs to write a filter to do so.)
2065 *) Input filters and ap_get_brigade() now have a input mode parameter
2066 (blocking, non-blocking, peek) instead of a length parameter.
2069 *) Update the mime.types file to the registered media types as
2070 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2073 *) Namespace protect some macros declared in ap_config.h
2076 *) Support HTTP header line folding with input filtering.
2079 *) Mod_include works again. This should still be re-written, but at
2080 least now we can serve an SHTML page again.
2083 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2084 to both the BUFF and the socket in the conn_rec. Functions that
2085 want to use the BUFF can, functions that want to use the socket,
2086 can. They point to the same place.
2089 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2090 [Tomas "Ögren" <stric@ing.umu.se>]
2092 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2093 associated pool goes away. (APR pipes on OS/2 were already had this
2094 logic.) This resolvs a fatal file descriptor leak with CGIs.
2097 *) The final line of the config file was not being read if there was
2098 no \n at the end of it. This was caused by apr_fgets returning
2099 APR_EOF even though we had read valid data. This is solved by
2100 making cfg_getline check the buff that was returned from apr_fgets.
2101 If apr_fgets return APR_EOF, but there was data in the buf, then we
2102 return the buf, otherwise we return NULL.
2105 *) Piped logs work again in the 2.0 series.
2108 *) Restore functionality broken by the mod_rewrite security fix:
2109 rewrite map lookup keys and default values are now expanded
2110 so that the lookup can depend on the requested URI etc.
2111 PR #6671 [Tony Finch]
2113 *) Tighten up the syntax checking of Host: headers to fix a
2114 security bug in some mass virtual hosting configurations
2115 that can allow a remote attacker to retrieve some files
2116 on the system that should be inaccessible. [Tony Finch]
2118 *) Add a pool bucket type. This bucket is used for data allocated out
2119 of a pool. If the pool is cleaned before the bucket is destroyed, then
2120 the data is converted to a heap bucket, allowing it to survive the
2124 *) Add a flush bucket. This allows modules to signal that the filters
2125 should all flush whatever data they currently have. There is no way
2126 to actually force them to do this, so if a filter ignores this bucket,
2127 that's life, but at least we can try with this.
2130 *) Add an output filter for sub-requests. This filter just strips the
2131 EOS bucket so that we don't confuse the main request's core output
2132 filter by sending multiple EOS buckets. This change also makes sub
2133 requests start to send EOS buckets when they are finished.
2136 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2137 makes ap_bucket_destroy a return void, which is okay because it
2138 used to always return APR_SUCCESS, and nobody ever checked its
2139 return value anyway.
2140 [Cliff Woolley <cliffwoolley@yahoo.com>]
2142 *) Remove the index into the bucket-type table from the buckets
2143 structure. This has now been replaced with a pointer to the
2144 bucket_type. Also add some macros to test the bucket-type.
2147 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2148 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2149 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2150 All _VAR_ flavors changes to _DATA to be absolutely clear.
2153 *) Add support for /, //, //servername and //server/sharename
2154 parsing of <Directory> blocks under Win32 and OS2.
2155 [Tim Costello, William Rowe, Brian Harvard]
2157 *) Remove the function pointers from the ap_bucket type. They have been
2158 replaced with a global table. Modules are allowed to register bucket
2159 types and use then use those buckets.
2162 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2163 once we finish writing the request body to the cgi child process;
2164 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2165 worked without this change (for reasons I don't understand), but large
2166 ones didn't. [Jeff Trawick]
2168 *) Remove file bucket specific information from the ap_bucket type.
2169 This has been moved to a file_bucket specific type that hangs off
2170 the data pointer in the ap_bucket type.
2173 *) Input filtering now has a third argument. This is the amount of data
2174 to read from lower filters. This argument can be -1, 0, or a positive
2175 number. -1 means give me all the data you have, I'll deal with it and
2176 let you know if I need more. 0 means give me one line and one line
2177 only. A positive number means I want no more than this much data.
2179 Currently, only 0 and a positive number are implemented. This allows
2180 us to remove the remaining field from the conn_rec structure, which
2184 *) Big cleanup of the input filtering. The goal is that http_filter
2185 understands two conditions, headers and body. It knows where it is
2186 based on c->remaining. If c->remaining is 0, then we are in headers,
2187 and http_filter returns a line at a time. If it is not 0, then we are
2188 in body, and http_filter returns raw data, but only up to c->remaining
2189 bytes. It can return less, but never more.
2190 [Greg Ames, Ryan Bloom, Jeff Trawick]
2192 *) mod_cgi: Write all of the request body to the child, not just what
2193 the kernel would accept on the first write. [Jeff Trawick]
2195 *) Back out the change that moved the brigade from the core_output_filters
2196 ctx to the conn_rec. Since all requests over a given connection
2197 go through the same core_output_filter, the ctx pointer has the
2201 *) Fix another bug in the send_the_file() read/write loop. A partial
2202 send by apr_send would cause unsent data in the read buffer to
2203 get clobbered. Complete making send_the_file handle partial
2204 writes to the network.
2207 *) Fix a couple of type fixes to allow compilation on AIX again
2208 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2210 *) Fix bug in send_the_file() which causes offset to be ignored
2211 if there are no headers to send.
2214 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2215 filter. Useful for supporting Windows 9* with a binary
2216 compiled on Windows NT.
2219 Changes with Apache 2.0a7
2221 *) Reimplement core_output_filter to buffer/save bucket brigades
2222 across multiple calls to the core_filter. The brigade will be
2223 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2224 thresholds are hit or the EOS bucket is received.
2227 *) Create experimental filter (buffer_filter) that coalesces bytes
2228 into one large buffer before invoking the next filter in the
2229 chain. This filter is particularly useful with the current
2230 implementation of mod_autoindex when it inserted above the
2231 chunk_filter. mod_autoindex generates a lot of brigades that
2232 containing buckets holding just a few bytes each. The
2233 buffer_filter coalesces these buckets into a single large bucket.
2236 *) Add apr_sendfile() support into the core_output_filter.
2239 *) Add apr_sendv() support into the core_output_filter.
2242 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2243 [Mike Abbott <mja@sgi.com>]
2245 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2246 make much sense, because Apache uses buckets instead of BUFFs now.
2249 *) send_the_file now falls back to a read/write loop on platforms that
2250 do not have sendfile.
2251 [Ryan Bloom and Brian Havard]
2253 *) Install apachectl correctly, and substitute the proper values so
2254 that it works again. [Ryan Bloom]
2256 *) Better(??) handle platforms that lack sendfile().
2259 *) APR now has UUID generation/formatting/parsing support.
2262 *) Begin the http_filter. This is an input filter that understands
2263 the absolute basic amount required to parse an HTTP Request. The
2264 goal is to be able to split headers from request body before passing
2265 the data back to the other filters.
2268 *) Bring forward from 1.3.13 the config directory implementation
2271 *) install apxs if it is created
2274 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2275 conversions. [William Rowe]
2277 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2278 ap_add_output_filter(). [Jeff Trawick]
2280 *) Multiple build and configuration fixes
2283 -add datadir and localstatedir substitutions
2285 -fix logfilename misspelling
2286 -fix evaluation of installation dir variables and
2287 -replace $foobar by $(foobar) to be usefull in the makefile
2291 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2292 $CC_FOR_BUILD is still missing
2293 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2294 -add missing "AR=@AR@" to severaly Makefile.in's
2295 -cache result for "struct rlimit"
2296 -compile all helper programs with native and cross compiler
2297 and use the native version to generate header file
2298 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2300 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2302 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2304 *) Fix a bug where a client which only sends \n to delimit header
2305 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2306 message. Start working on ebcdic co-existance with input
2308 [William Rowe, Greg Ames]
2310 *) If mod_so is enabled in the server always create libexec, even
2311 if there are no modules installed in this directory. This is a
2312 requirement for APXS to work correctly.
2315 *) Connection oriented output filters are now stored in the
2316 conn_rec instead of the request_rec. This allows us to add the
2317 output filter in the pre-connection phase instead of the
2318 post_read_request phase, which keeps us from trying to write an
2319 error page before we have a filter to write to the network.
2320 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2322 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2323 mmap can be used across multiple buckets (default_handler with
2324 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2325 the mmap itself can't be associated with the bucket.
2328 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2331 *) Radical surgery to improve mod_isapi support under Win32.
2332 Includes a number of newer ServerSupportFunction calls, support
2333 for ReadClient (in order to retrieve POSTs greater than 48KB),
2334 and general bug fixes to more reliably load ISAPI .dll's and
2335 prevent leaking handle resources. Note: There are still
2336 discrepancies between IIS's and Apache's ServerVariables, and
2337 async calls are still not supported. Additional warnings are
2338 logged to facilitate debugging of unsupported ISAPI calls.
2341 *) Add input filtering to Apache. The basic idea for the input
2342 filters is the same as the ideas for output filters. The biggest
2343 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2344 should be called, and the order of execution for the filter itself is
2345 different. When writing an output filter, a brigade is passed in,
2346 and filters operate directly on that brigade, when done, they call
2347 ap_pass_brigade. Input filters are the exact opposite. Because input
2348 is not a push operation, filters first call ap_get_brigade. When this
2349 function returns, the input filter will be left with a valid brigade.
2350 The input filter should then operate on the brigade, and return.
2353 *) Fix building on BSD/OS using its native make. The build system
2354 falls back to the BSD .include directive on that host platform.
2357 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2358 SHA1 and plaintext password encodings. Make feature tests a
2359 bit more flexible. [William Rowe]
2361 *) Charset translation: mod_charset_lite handles output content
2362 translation in a filter. mod_charset_lite no longer ignores
2363 subrequests. A bunch of cruft related to BUFF's support for
2364 translating request and response bodies was removed.
2367 *) Move the addition of the CORE filter to the post_read_request
2368 hook in http_core.c. This removes the need to add the filter in
2369 multiple places and allows for an SSL module to be added much
2370 simpler. [Ryan Bloom]
2372 *) Fix a security problem that affects certain configurations of
2373 mod_rewrite. If the result of a RewriteRule is a filename that
2374 contains expansion specifiers, especially regexp backreferences
2375 $0..$9 and %0..%9, then it may be possible for an attacker to
2376 access any file on the web server. [Tony Finch]
2378 *) Fix a bug where errors that are detected during early request parsing
2379 don't produce visible HTTP error messages at the browser, because
2380 the core_filter wasn't present. [Greg Ames]
2382 *) Provide apr_socklen_t as a portability aid.
2383 [Victor J. Orlikowski]
2385 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2386 as well as a comment arg to the add, adduser and update cmds.
2387 update allows the user to clear or preserve pw/groups/comment.
2388 Fixed a bug in dbmmanage that prevented the check option from
2389 parsing a password followed by :group... text. Corrected the
2390 seed calcualation for Win32 systems, and added -lsdbm support.
2393 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2396 *) Avoid a segfault when parsing .htaccess files. An
2397 uninitialized tree pointer was passed to ap_build_config().
2400 *) Change the way that inet_addr & inet_network are checked for
2401 in APR's configure process to allow BeOS BONE to correctly
2402 find them. With this change BeOS BONE now builds from source
2403 with no problems. [David Reid]
2405 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2406 the end of the parameters to execve() was stored in the wrong
2407 location, overlaying the storage beyond the newargs[] array and
2408 also passing uninitialized storage to execve(), which would
2409 sometimes fail with EFAULT. [Jeff Trawick]
2411 *) Fix a bug parsing configuration file containers. With a sequence
2412 like this in the config file
2414 <IfModule mod_kilroy.c>
2417 <IfModule mod_lovejoy.c>
2422 the second container would be terminated at the blank line due to
2423 sediment in the buffer from reading the prior </IfModule> and an
2424 error message would be generated for the real </IfModule> for the
2425 second container. Also due to this problem, any two characters
2426 could be used for "</" in the close of a container.
2429 *) ap_add_filter prototype changed to remove the ctx pointer. The
2430 pointer still remains in the filter structure, but it can not be
2431 a part of the ap_add_filter prototype. The reason is that when
2432 the core uses AddFilter to add a filter to the stack it doesn't
2433 know how to allocate the ctx pointer, or even how much memory should
2434 be allocated. The filters will have to be responsible for allocating
2435 the ctx memory when they need it.
2438 *) Add an AddFilter directive. This directive takes a list of filters
2439 that should be activated for the requested resource.
2442 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2443 some other platforms). [Jeff Trawick]
2445 *) Modify mod_include to be a filter. Currently, it has only been tested
2446 on actual files, but it should work for CGI scripts too.
2449 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2450 writes. apr_flush() for Unix: handle interrupted writes.
2453 *) NameVirtualHost can now take "*" as an argument instead of
2454 an IP address. This allows you to create a purely name-based
2455 virtual hosting server that does not have any IP addresses in
2456 the configuration file and which ignores the local address
2457 of any connections. PR #5595, PR #4455 [Tony Finch]
2459 *) Fix some compile warnings in mod_mmap_static.c
2460 [Mike Abbott <mja@sgi.com>]
2462 *) Fix chunking problem with CGI scripts. The general problem was that
2463 the CGI modules were adding an EOS bucket and then the core added an
2464 EOS bucket. The chunking filter finalizes the chunked response when it
2465 encounters an EOS bucket. Because two EOS buckets were sent, we
2466 finalized the response twice. The fix is to make sure we only send one
2467 EOS, by utilizing a flag in the request_rec.
2470 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2471 and Win32. Previously, the first read from an apr_file_t set up via
2472 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2474 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2475 bucket, instead of using BUFF's and ap_r*.
2478 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2479 [Mike Abbott <mja@sgi.com>]
2481 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2482 code to use APR file's directly instead of going through BUFFs.
2485 *) Fix compile break on some platforms for mod_mime_magic.c
2486 [John K. Sterling <sterling@covalent.net>]
2488 *) Fix merging of AddDefaultCharset directive.
2489 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2491 *) Minor revamp of the rlimit sections of code. We now test
2492 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2493 is now "available" even if the platform doesn't support
2494 the rlimit family (it's just a noop though). [Jim Jagielski]
2496 *) Migrate the pre-selection of which MPM to use for specific
2497 platforms to hints.m4, which contains (or should contain)
2498 all platform specific "hints". [Jim Jagielski]
2500 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2503 *) Add tables with non-string/binary values to APR.
2506 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2509 *) Update PCRE to version 3.2. [Ryan Bloom]
2511 *) Change the way buckets' destroy functions are called so that
2512 they can be more directly used when changing the type of a
2513 bucket in place. [Tony Finch]
2515 *) Add generic support for reference-counting the resources used by
2516 buckets, and alter the HEAP and MMAP buckets to use it. Change
2517 the way buckets are initialised to support changing the type of
2518 buckets in place, and use it when setting aside TRANSIENT buckets.
2519 Change the implementation of TRANSIENT buckets so that it can be
2520 mostly shared with IMMORTAL buckets, which are now implemented.
2523 Changes with Apache 2.0a6
2525 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2527 *) Add a chunking filter to Apache. This brings us one step closer
2528 to removing BUFF. [Ryan Bloom]
2530 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2531 added to the stack is the last filter to be called. [Ryan Bloom]
2533 *) Apache 2.0 has been completely documented using Scandoc. The
2534 docs can be generated by running 'make docs'. [Ryan Bloom]
2536 *) Add filtered I/O to Apache. This is based on bucket brigades,
2537 Currently the buckets still use BUFF under the covers, but that
2538 should change quickly. The only currently written filter is the
2539 core filter which just calls ap_bwrite. [The Apache Group]
2541 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2542 built with thread support. [Jeff Trawick]
2544 *) Abort configuration if --with-layout was specified and there's
2545 no layout definition file. [Ken Coar]
2547 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2549 *) Add support for extension methods for the Allow response header
2550 field, and an API routine for accessing r->allowed and the
2551 list of extension methods in a unified manner. [Ken Coar]
2553 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2554 [Rob Simonson <simo@us.ibm.com>]
2556 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2557 APACHE_XLATE builds. [Jeff Trawick]
2559 *) A configuration file parsing problem was fixed. When the
2560 configuration file started with an IfModule/IfDefine container,
2561 only the last statement in the container would be retained.
2564 Changes with Apache 2.0a5
2566 *) Perchild is serving pages after passing them to different child
2567 processes. There are still a lot of bugs, but this does work. I
2568 have made requests against the same installation of Apache, and had
2569 different servers use different user IDs to serve the responses.
2570 This change moves to using socketpair instead of an AF_UNIX socket.
2573 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2574 It can't seem to pass between child processes yet, but I think we
2575 are closer now than before. This moves us back to using Unix
2576 Domain Sockets. [Ryan Bloom]
2578 *) libapr functions and types renamed with apr_ prefix.
2579 #include "apr_compat.h" for 1.3.x backwards compat
2582 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2583 return the right information on the local socket address.
2584 [Gregory Nicholls <gnicholls@level8.com>]
2586 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2587 [Gregory Nicholls <gnicholls@level8.com>]
2589 *) Add an option to not detach from the controlling terminal without
2590 going into single process mode. This allows for much easier
2591 debugging of the process startup code. [Ryan Bloom]
2593 *) ab: don't use perror() to report the failure of an APR function.
2596 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2597 scoreboard on graceful restarts.
2600 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2601 An invalid ap_proc_t was passed to ap_create_process().
2604 *) Allow modules to register filters. Those filters are still
2605 never called, but this is a step in the right direction.
2606 [Ryan Bloom and Greg Stein]
2608 *) Register the mod_cgid daemon process for cleanup so that it is
2609 killed at termination if it does not die when the parent gets
2610 SIGTERM. This change is to fix occasional problems where the
2611 process stays around. Bugs in similar logic in mod_rewrite and
2612 mod_include were also fixed. [Jeff Trawick]
2614 *) Fix a bug in the time handling. Basically, we were imploding a time
2615 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2616 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2617 uses those two fields to adjust the time value. Because of the HTTP
2618 spec, both of those values can be zero'ed out safely. This fixes
2619 the bug correctly. [Ryan Bloom]
2621 *) Fix a couple of place in the Windows code where the wrong error
2622 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2624 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2626 *) Added the APR_EOL_STR macro for platform dependent differences in
2627 logfiles and other raw text (such as all APR files). Fixes logfiles
2628 not terminated with cr/lf sequences in Win32. [William Rowe]
2630 *) Move all strings functions in APR to src/lib/apr/strings and create
2631 apr_strings.h for the prototypes. [Ryan Bloom]
2633 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2634 to repeat the syscall until we stop getting EINTR. I noticed a
2635 related problem at termination (SIGTERM) on FreeBSD when using
2636 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2637 implementation work properly with child init. Previously, ap_lock()
2638 was essentially a no-op because all children were using different
2639 locks and thus nobody ever blocked. [Jeff Trawick]
2641 *) The htdocs/ tree has been moved out of the CVS source tree into
2642 a separate area for easier development. This has NO EFFECT on
2643 end-users or Apache installations. [Ken Coar]
2645 *) Integrate the mod_dav module for WebDAV protocol handling. This
2646 adds the dav and dav_fs modules, the SDBM library, and additional
2647 XML handling utilities. [Greg Stein]
2649 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2652 *) Update the lib/expat-lite/ library (bring forward changes from
2653 the Apache 1.3 repository). [Greg Stein]
2655 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2656 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2658 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2659 machines where sendfile is detected, but nobody has written ap_sendfile.
2660 [Dave Hill <ddhill@zk3.dec.com>]
2662 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2664 *) ab would start up more connections than needed, then quit when the
2665 desired number were finished. Also fixed a logic error involving
2666 ab keepalives. [Victor J. Orlikowski]
2668 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2669 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2670 timeouts (i.e, if a timeout was specified, the pipe reverted to
2671 a full blocking pipe). Now the behaviour is more in line with
2672 Unix non-blocking pipes.
2675 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2676 cache open file handles along with accept socket reuse enables
2677 Apache 2.0 to serve non-keepalive requests for static files at
2678 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2679 and Apache 2.0 will serve almost 1200 rps on my system).
2682 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2683 supports two config directives, mmapfile (same behavious as
2684 mod_mmap_static) and cachefile. Use the cachefile directive
2685 to cache open file handles. This directive only works on systems
2686 that have implemented the ap_sendfile API. cachefile works today
2687 on Windows NT, but has not been tested on any flavors of Unix.
2690 *) Cleanup the configuration. With the last few changes the
2691 configuration process automatically:
2692 inherits information about how to build from APR. Allowing
2693 APR to inform Apache that it should or should not use -ldl
2695 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2696 based on the threading model
2698 Apache calls APR's configure process before finishing it's
2699 configuration processing, allowing for more information flow
2704 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2705 with non-zero argument makes the socket non-blocking. BeOS and
2706 OS/2 already worked this way. [Jeff Trawick]
2708 *) ap_close() now calls ap_flush() for buffered files, so write
2709 operations work a whole lot better on buffered files.
2712 *) Fix error messages issued from MPMs which explain where to change
2713 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2716 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2717 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2718 now the way that the blocking state of a pipe is manipulated.
2719 ap_block_pipe() is gone. [Jeff Trawick]
2721 *) Correct the problem where the only local host name that the IP stack
2722 can discover are 'undotted' private names. If no fully qualified
2723 domain name can be identified, the default ServerName will be set to
2724 the machine's IP address string. A warning is always provided if the
2725 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2727 *) Repair problems with config file processing which caused segfault
2728 at init when virtual hosts were defined and which caused ServerName to
2729 be ignored when there was no valid DNS setup. [Jeff Trawick]
2731 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2733 *) Add ap_sendfile implementation for AIX
2734 [Victor J. Orlikowski]
2736 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2737 apr_network_io.h, and apr_thread_proc.h.
2738 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2740 *) Bring the allocation and pool debugging code back into a working
2741 state. This will need to be tested as so far it's only been used on
2744 *) Change configuration command setup to be properly typesafe when in
2745 maintainer mode. Note that this requires a compiler that can initialise
2746 unions. [Ben Laurie]
2748 *) Turn on buffering for config file reads. Part of this was to
2749 repair buffered I/O support in Unix and implement buffered
2750 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2752 *) Win32: Fix problem where UTC offset was not being set correctly
2753 in the access log. Problem reported on news group by Jerry Baker.
2756 *) Fix segfault when reporting this type of syntax error:
2757 "</container> without matching <container> section", where
2758 container is VirtualHost or Directory or whatever.
2761 *) Prevent the source code for CGIs from being revealed when using
2762 mod_vhost_alias and the CGI directory is under the document root
2763 and a user makes a request like http://www.example.com//cgi-bin/cgi
2764 as reported in <news:960999105.344321@ernani.logica.co.uk>
2767 *) Add support for the new Beos NetwOrking Environment (BONE)
2770 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2771 final input char is incomplete; ap_bwrite_xlate() now handles
2772 incomplete final input chars. [Jeff Trawick]
2774 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2775 that a bhalfduplex call occurs before logging or else DNS and
2776 such can delay the last packet of the response. [Dean Gaudet]
2778 *) Some syscall reduction in APR on unix -- don't seek when setting
2779 up an mmap; and don't fcntl() more than once per socket.
2782 *) When mod_cgid is started as root, the cgi daemon now switches
2783 to the configured User/Group (like other httpd processes)
2784 instead of continuing as root. [Jeff Trawick]
2786 *) The prefork MPM now uses an APR lock for the accept() mutex.
2787 It has not been getting a lock at all recently. httpd -V now
2788 displays APR's selection of the lock mechanism instead of the
2789 symbols previously respected by prefork. [Jeff Trawick]
2791 *) Change the mmap() feature test to check only for existence.
2792 The previous check required features not used by Apache.
2795 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2796 sometimes mangled. The len parm to accept() was not
2797 initialized, leading sometimes to an endless loop of failed
2798 accept() calls on OS/390 and anywhere else that failed the call
2799 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2800 instead of declaring it ourselves to fix a compilation problem
2801 on Solaris. [Jeff Trawick]
2803 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2805 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2807 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2809 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2810 initialization if ALLOC_DEBUG is defined; no known symptom
2811 otherwise. [Jeff Trawick]
2813 *) Fix typo in configure script when checking for mod_so. bash
2814 doesn't seem to have a problem but /bin/sh on Solaris does.
2815 Symptom: "./configure: test: unknown operator =="
2818 *) Rebind the Win32 NT and 9x services control into the MPM.
2819 All console, WinNT SCM and Win9x pseudo-service control code is
2820 now wrapped within the WinNT MPM.
2823 *) Make a copy of getenv("PATH") before storing for later use. Some
2824 getenv() implementations use the same storage for successive calls.
2825 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2827 *) Server Tokens work in 2.0 again. This also propogates the change
2828 to allow just the product name in the server string using
2832 Changes with Apache 2.0a4
2834 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2835 won't need to call it. [Greg Ames, Jeff Trawick]
2837 *) Move pre_config hook call to between configuration read and config
2838 tree walk. This allows all modules to implement pre_config hooks
2839 and know that they will be called at an appropriate time.
2842 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2845 *) Add pre-config hooks back to all modules.
2848 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2849 ContentDigest enabled and we can't/don't mmap the file.
2852 *) We now report the correct line number for syntax errors in config
2853 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2855 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2856 related bugs, and changed shmem/locking to use apr API. Shared-mem
2857 is currently disabled, however, because of problems with graceful
2858 restarts. [Ronald Tschalär]
2860 *) Fix corruption of IFS variable in --with-module= handling.
2861 Depending on the user's shell or customization thereof, there
2862 would be errors generating ap_config_auto.h later in the configure
2863 procedure. [Jeff Trawick]
2865 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2866 isn't used (as in 1.3), except that on Unix it is now logged via
2867 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2868 to the error log. [Greg Ames, Jeff Trawick]
2870 *) Add '-D' argument processing for run time configuration defines.
2873 *) Organize http_main.c as independent code, such that no code or
2874 global data is exported from it. WIN32 will dynamically link it
2875 to the server core, so this will prevent mutual dependency.
2878 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2879 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2882 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2883 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2885 *) Add mod_charset_lite for configuring character set translation.
2888 *) Add '-n' option to htpasswd to make it print its user:pw record
2889 on stdout rather than having to frob a text file. [Ken Coar]
2891 *) Fix saferead. Basically, we flush the output buffer if a read on the
2895 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2896 a conversion is single-byte only. [Jeff Trawick]
2898 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2899 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2902 *) Fix some minor errors where pid was being manipulated as an int
2903 instead of the portable pid_t. [Roy Fielding]
2905 *) Fix some error log prints that were printing the pointer to a
2906 structure rather than the pid within the structure.
2907 [Jeff Trawick, Roy Fielding]
2909 *) ab: Fix a command-line processing bug; track bad headers in
2910 err_response; support reading headers up to 2K.
2911 [Ask Bjoern Hansen <ask@valueclick.com>]
2913 *) Fix ap_resolve_env() so that it handles new function added in a prior
2914 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2915 config file.") as well as the constructs used by mod_rewrite.
2916 [Paul Reder <rederpj@raleigh.ibm.com>]
2918 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2920 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2921 APR to perform translation, instead of accessing the hard-coded tables
2922 in 1.3's ebcdic.c. [Jeff Trawick]
2924 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2927 *) Add the ability to hook into the config file reading phase. Basically
2928 if a directive is specified EXEC_ON_READ, then when that directive is
2929 read from the config file, the assocaited function is executed. This
2930 should only be used for those directives that must muck with HOW the
2931 server INTERPRETS the config. This should not be used for directives
2932 that re-order or replace items in the config tree. Those changes should
2933 be made in the pre-config step.
2936 *) Add mod_example to the build system.
2939 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2940 byte character sets. [Jeff Trawick]
2942 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2943 Kraemer and Oliver Reh originally according to the change log).
2946 *) Fix a couple of problems in RFC1413 support (controlled by the
2947 IdentityCheck directive). Apache did not build the request string
2948 properly and more importantly Apache would loop forever if the
2949 would-be ident server dropped the connection before sending a
2950 properly terminated response. [Jeff Trawick]
2952 *) apxs works in 2.0.
2955 *) Reliable piped logs work in 2.0.
2958 *) Introduce a hash table implementation into APR to be used for
2959 replacing tables and other random data structures in Apache.
2962 *) Add some more error reporting to htpasswd in the case of problems
2963 generating or accessing the temporary file. Also, pass in a
2964 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2965 is defined). [Ken Coar]
2967 *) Configure creates config.nice now containing your configure
2968 options. Syntax: ./config.nice [--more-options]
2971 *) Fix various return code problems in APR on Win32. For most of
2972 these, APR was returning APR_EEXIST instead of GetLastError()/
2973 WSAGetLastError(). [Jeff Trawick]
2975 *) Make piped logs work again in version 2.0
2978 *) Add VPATH support to UNIX build system of Apache and APR.
2981 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2985 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2986 Patch submitted to author.
2989 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2990 /sbin in PATH on FreeBSD (all submitted to rse previously)
2993 *) Fix building Pthread-based MPMs on OpenBSD
2994 [Sascha Schumann] PR#26
2996 *) Fix ap_readdir() problem on systems where d_name[] field in
2997 struct dirent is declared with only one byte. (This problem only
2998 affected multithreaded builds.) This caused a segfault during
2999 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
3000 least). [Jeff Trawick]
3002 *) Fix some make-portability problems on at least Tru64, Irix
3004 [Sascha Schumann] PR#18, PR#39
3006 *) Add ap_sigwait() to support old-style sigwait() on systems
3007 like OS/390 and UnixWare.
3010 *) Add POSIX-thread flags for more platforms.
3013 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
3014 (on Unix, at least) to handle resolver errors. Fix a bug in
3015 the definition of APR_ENOMEM so that ap_strerror() can spit
3016 out the correct error message for it.
3019 Changes with Apache 2.0a3
3021 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
3024 *) API: *HOOK* macros now have an AP_ prefix
3027 *) Win32: Eliminate redundant calls to initialize winsock.
3028 [Tim Costello <timcostello@ozemail.com.au>]
3030 *) Fix bugs initializing ungetchar for pipes.
3031 [Chia-liang Kao <clkao@CirX.ORG>]
3033 *) The ab program in the src/support directory is now portable using
3037 *) Support directory is being compiled when the server is built
3040 *) The configure option --with-program-name has been added to allow
3041 developers to rename the executable at configure time. This also
3042 changes the name of the config files to match the executable's name.
3045 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3046 containing version numbers. [Martin Pool]
3048 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3049 Unix; access_log and error_log now created with these perms; non-
3050 Unix is unaffected [Jeff Trawick]
3052 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3053 Replaced more magic numbers with MD5_DIGESTSIZE.
3054 [William Rowe, Roy Fielding]
3056 *) Win32: Get mod_auth_digest compiling and added to the Windows
3057 build environment. Not tested and I'd be suprised if it
3058 actually works. [Bill Stoddard]
3060 *) Revamp the Win32 make environment. Makefiles have been removed and
3061 Apache.dsw created to bring together all the pieces. Create new file
3062 os/win32/BaseAddr.ref to define module base addresses (to prevent
3063 dll relocation at start-up).
3064 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3066 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3067 of the \015, \012, and \015\012 constants with macros.
3068 [Greg Ames <gregames@us.ibm.com>]
3070 *) Add ap_xlate_open() et al for translation of text between different
3071 character sets. The initial implementation requires iconv().
3074 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3075 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3077 *) CGI output is being timed out now.
3080 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3081 is used by the new apr file. There is no reason to create a new file
3082 with the same lifetime as the original file.
3085 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3086 module base addresses. This will help shooting seg faults
3087 in the field. [William Rowe <wrowe@lnd.com>]
3089 *) Update Apache on Windows documentation. Add new document
3090 describing how to compile Apache on Windows.
3091 [William Rowe <wrowe@lnd.com>]
3093 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3094 microseconds instead of seconds. Some storage leaks and other
3095 minor bugs in related code were fixed. [Jeff Trawick]
3097 *) Win32: First cut at getting mod_isapi working under 2.0
3098 [William Rowe <wrowe@lnd.com>]
3100 *) First stab at getting mod_auth_digest working under 2.0
3101 quick change summary:
3102 - moved the random byte generation (ap_generate_random_bytes) into APR
3103 - now uses ap_time_t
3104 - compiles and runs on linux
3106 [Brian Martin <bmartin@penguincomputing.com>]
3108 *) Win32: Move the space stripping of physical service names
3109 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3110 unresolved symbol. Add dependency checking to the
3111 CreateService call to ensure TCPIP and AFP (winsock) is started
3113 [William Rowe <wrowe@lnd.com>]
3115 *) Win32: Add code to perform latebinding on functions that may
3116 not exist on all levels of Windows where Apache runs. This
3117 is needed to allow Apache to start-up on Win95/98. All calls
3118 to non portable functions should be protected with
3119 ap_oslevel checks to prevent runtime segfaults.
3120 [William Rowe <wrowe@lnd.com>]
3122 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3124 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3126 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3127 This addresses PR 1623. Still need to address timing out runaway
3128 CGI scripts. [Bill Stoddard]
3130 *) Win32: Make ap_stat Windows 95/98 friendly
3131 [William Rowe <wrowe@lnd.com>]
3133 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3134 always fail. Need to initialise the dwOSVersionInfoSize member of the
3135 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3138 The patch also enhances ap_get_oslevel (and the associated enum) to
3139 handle selected service packs for NT4, and adds recognition for
3140 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3141 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3142 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3144 *) Get mod_rewrite building and running, and mod_status building for Win NT
3145 [Allan Edwards <ake@raleigh.ibm.com>]
3147 *) Patch to port mod_auth_db to the 2.0 api and also to support
3148 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3149 2.7.7. It should work with version 1 as well but I haven't tested it.
3150 [Brian Martin <bmartin@penguincomputing.com>]
3152 *) Get APR DSO code working under Windows. Includes cross platform
3154 [Tim.Costello@BTFinancialgroup.com]
3156 *) Fix some of the Windows APR time functions.
3159 *) FAQ changes related to tidying up historical documents on the web site.
3160 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3162 *) Move Windows DSO code into APR.
3165 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3166 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3167 at build time. At this point, the server will not compile on Windows because
3168 of the recent DSO commits. Fixing those next.
3169 [Bill Rowe & Bill Stoddard]
3171 *) Added error checking for file I/O APR routines.
3172 [Jon Travis <jtravis@covalent.net>]
3174 *) APR: Don't use the values of resolver error codes for the
3175 corresponding APR error codes. On Unix and Win32, return the
3176 proper APR error code after a resolver error. [Jeff Trawick]
3178 Changes with Apache 2.0a2
3180 *) Renamed the executable back to httpd on all platforms other
3184 *) Allow BeOS to survive restarts, log properly and a few
3185 small things it had problems with due to the way it setup
3186 users and groups. [David Reid]
3188 *) Get mod_rewrite working with APR locks
3189 [Paul Reder <rederpj@raleigh.ibm.com>]
3191 *) Actually remove the sempahore when the lock cleanup routine
3192 is called on BeOS. [David Reid]
3194 *) Clear hook registrations between reads of the config file.
3195 When DSOs are unloaded and re-loaded the old hook pointers may
3196 no longer be valid. This fix eliminates potential segfaults.
3197 [Allan Edwards <ake@raleigh.ibm.com>]
3199 *) Fix a problem with Sigfunc not being defined or bypassed
3200 if sigaction() wasn't found. [Jim Jagielski]
3202 *) Fix the locking mechanism on BSD variants. They now use fcntl
3203 locks. This allows the server to start and serve pages.
3206 *) First cut at getting the Win32 installer to work
3207 [William Rowe <wrowe@lnd.com>]
3209 *) Get htpasswd compiling under Windows
3210 [William Rowe <wrowe@lnd.com>]
3212 *) Change the log message for a bind() failure to show the
3213 interface and port number. [Jeff Trawick]
3215 *) Import the documentation from 1.3.12 and bring parts of it
3216 up-to-date with respect to the changes that have occurred
3220 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3221 now logged correctly on BeOS.
3224 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3225 Makefile.win includes the same user interface as the old
3227 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3229 *) Win32 exec now uses COMSPEC environment string for command
3230 shell path resolution.
3231 [William Rowe <wrowe@lnd.com>] PR#3715
3233 *) Win32: ap_connect() was not returning correct error condition
3235 [Allen Prescott <allen@clanprescott.com>]
3237 *) Win32: ap_open() was broken on Win9x because an NT-specific
3238 flag was passed to CreateFile. ap_puts() added an unnecessary
3240 [Jeff Trawick <trawick@us.ibm.com>]
3242 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3243 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3244 confusing ee/et name and made all extensions language/dialect
3245 rather than country reflecting. Changed example files to
3246 explicit reflect the ISO charset and added a few common
3247 ones to the example config [dirkx]
3249 *) Extend external module capability. To use this, you call
3250 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3253 *) Backported the various "default charset" fixes from 1.3.12,
3254 including the AddDefaultCharset directive. [Jim Jagielski]
3256 *) Added the capability to do ${ENVVAR} constructs in the
3257 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3258 it does this on a line by line basis; i.e. if the envvar
3259 expands to something with spaces you have to protect it
3260 by adding quotes around it (Unless of course you expect it
3261 to contains more than one argument. Alternatively you
3262 can compile it on a per token basis; which is what people
3263 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3264 hampers fancier hacks.
3265 [Dirk-Willem van Gulik]
3267 *) Changed the 'ErrorDocument' syntax in that it NO longer
3268 supports the asymetric
3270 ErrorDocument 301 "Some message
3272 Note the opening " quote, without a closing quote. It now
3273 has either the following syntaxes
3275 ErrorDocument XXX /local/uri
3276 ErrorDocument XXX http://valid/url
3277 ErrorDocument XXX "Some Message"
3279 The recognition heuristic is: if it has a space it
3280 is a message. If it has no spaces and starts with a /
3281 or is a valid URL then treat it that way. Otherwise it
3282 is assumed to be a message.
3284 This breaks backward compatibility but makes live a hell
3285 of a lot easier for GUI's and config file parsers.
3286 [Dirk-Willem van Gulik]
3288 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3289 syntax into a 'on' or 'off' syntax. As it currently is the
3290 only non nesting token which uses NO_ARGS and thus is an
3291 absolute pain for any config interface automation. This
3292 breaks backward compatibility. [Dirk-Willem van Gulik]
3294 *) Add ability to add external modules to the build process. This is
3295 done with --with-module=/path/to/module. Modules can only be added
3296 as static modules at this point.
3299 Changes with Apache 2.0a1
3301 *) Fix FreeBSD 3.3 core dump.
3302 Basically, ap_initialize() needs to get called before
3303 create_process(), since create_process() passes op_on structure
3304 to semop() to get a lock, but op_on isn't initialized until
3305 ap_initialize() calls setup_lock(). Here is a slight
3306 rearrangement to main() which calls ap_initialize() earlier...
3307 [Jeff Trawick <trawick@us.ibm.com>]
3309 *) Enable Apache to use sendfile/TransmitFile API
3310 [Bill Stoddard, David Reid, Paul Reder]
3312 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3316 *) Make file I/O and network I/O writev/sendv APIs consistent.
3317 Eliminate use of ap_iovec_t and use Posix struct iovec.
3318 Use seperate variable on ap_writev to set the number of iovecs
3319 passed in and number of bytes written.
3322 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3323 with ap_create_file_iol(). ap_create_file_iol() requires that
3324 the file be opened prior to the call using ap_open().
3327 *) Port mod_include and mod_cgi to 2.0
3328 [Paul Reder, Bill Stoddard]
3330 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3331 bytes_read/bytes_written is always valid (never -1). Plus
3332 some fixes to buff.c to correct problems introduced by the
3333 errno => ap_status_t changes a while back. Plus a fix to
3334 chunked encoding introduced right at the beginning of 2.0.
3337 *) Revamped UNIX build system to use autoconf and libtool.
3338 [Manoj Kasichainula, Sascha Schumann]
3340 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3342 *) More rigorous checking of Host: headers to fix security problems
3343 with mass name-based virtual hosting (whether using mod_rewrite
3344 or mod_vhost_alias).
3345 [Ben Hyde, Tony Finch]
3347 *) Add back support for UseCanonicalName in <Directory> containers.
3348 [Manoj Kasichainula]
3350 *) Added APLOG_STARTUP log type. This allows us to write an error
3351 message without any of the date and time information. As a part
3352 of this change, I also removed all of the calls to fprintf(stderr
3353 and replaced them with calls to ap_log_error using APLOG_STARTUP
3354 writing to stderr is no longer portable, because we don't direct
3355 stderr to the error log on all platforms.
3358 *) Convert error logging functions to take errno as an argument.
3359 This makes our error logs more portable, because some Windows API's
3360 don't set errno. This change allows us to still output a valid
3361 message on all of our platforms.
3364 *) mod_mime_magic runs in 2.0-dev now.
3365 [Paul Reder <rederpj@raleigh.ibm.com>]
3367 *) sendfile has been added to APR.
3368 [John Zedlewski <zedlwski@Princeton.EDU>]
3370 *) buff.c has been converted to no longer use errno.
3371 [Manoj Kasichainula]
3373 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3374 interface adaption to APR functions did it. [Martin Kraemer]
3376 *) Support DSOs properly on 32-bit HP-UX 11.0
3377 [Dilip Khandekar <dilip@cup.hp.com>]
3379 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3380 [Ralf S. Engelschall]
3382 *) Cleaned APR build environment integration and bootstrap APR
3383 automatically for developers from src/Configure.
3384 [Ralf S. Engelschall]
3386 *) Fixed building of src/support/htpasswd.c
3387 [Ralf S. Engelschall]
3389 *) When generating the Location: header, mod_speling forgot
3390 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3393 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3395 *) Change all pools to APR contexts. This is the first step to
3396 incorporating APR into Apache. [Ryan Bloom]
3398 *) Move "handler not found" warning message to below the check
3399 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3400 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3402 *) Support line-continuation feature in config.option file and
3403 allow the loading of multiple option sections at once via
3404 ``--with-option=<section1>,<section2>,...''
3405 [Ralf S. Engelschall]
3407 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3409 Changes with Apache MPM
3411 *) Use asynchronous AcceptEx() and a completion port to accept and
3412 dispatch connections to threads in Windows NT/2000.
3415 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3418 *) Implement the APACI --with-option facility
3419 (per default used the config.option file).
3420 [Ralf S. Engelschall]
3422 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3424 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3425 Replace pre_connection module call with a register_hook call and
3426 implement pre_connection as a hook. The intent is that these hooks will
3427 be extended to allow Apache to be multi-protocol, and also to allow the
3428 calling order to be specified on a per-hook/per-module basis.
3431 *) Implement mpm_* methods as "modules". Each method gets its own
3432 subdir in src/modules (eg: src/modules/prefork). Selection
3433 of method uses Rule MPM_METHOD. [Jim Jagielski]
3435 *) Port the hybrid server from the apache-apr repository as
3436 mpm_mpmt_pthread. [Manoj Kasichainula]
3438 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3439 amongst the unix MPMs.
3441 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3442 signal handling for the new world order. [Dean Gaudet]
3444 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3445 of alloc.c for now. [Dean Gaudet]
3447 *) Handle partial large writes correctly. [Ben Laurie]
3449 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3450 based on IP/port. [Ben Laurie]
3452 *) Port a bunch of modules to the new module structure.
3453 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3455 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3457 *) Basic restructuring to introduce the MPM concept; includes various
3458 changes to the module API... better described by
3459 docs/initial_blurb.txt. [Dean Gaudet]
3461 Changes with Apache pthreads
3463 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3464 buff operations (generally over a network).
3465 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3467 *) Created http_accept abstraction. Added 4 new functions (not exported):
3468 init_accept(), begin_accepting_requests(), get_request(),
3469 stop_accepting_requests() [Bill Stoddard]
3471 *) Fix to ap_rprintf call that allows mod_info to work properly.
3472 [James Morris <jmorris@intercode.com.au>]
3474 *) user and ap_auth_type fields were moved from connection_rec to
3475 request_rec. [Ryan Bloom]
3477 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3478 needed in a threaded server.
3480 *) Initial pthread implementation from from Dean's apache-nspr code.
3481 [Bill Stoddard, Ryan Bloom]
3484 Changes with Apache 1.3.9
3486 *) Remove bogus error message when a redirect doesn't set Location.
3487 Instead, use an empty string to avoid coredump if the error message
3488 was supposed to include a location. [Roy Fielding]
3490 *) Don't allow configure to include mod_auth_digest unless it is
3491 explicitly requested, even if the user asked for all modules.
3494 *) Translate module names to dll names for OS/2 so that they are no more
3495 than 8 characters long and have an extension of "dll" instead of "so".
3498 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3499 Fix test-compile check to check for randbyte instead of trand32.
3500 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3501 and tweak to make Amaya happier. [Ronald Tschalär]
3503 *) Ensure that the installed expat include files are world readable,
3504 just like the other header files. [Martin Kraemer]
3506 *) Fixed generated AddModule adjustments in APACI's `configure' script
3507 in order to allow (new) modules like mod_vhost_alias to be handled
3508 correctly (which was touched by the adjustments for mod_alias).
3509 [Ralf S. Engelschall]
3511 *) For binary builds, add -R flag to apachectl to work around the lack of
3512 an absolute path to the ./libexec directory where the libhttp.ep file
3513 is needed for SHARED_CORE architectures. [Randy Terbush]
3515 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3516 problem observed by some Win95/98 users where they get CGI script
3517 output sent to the console. [Bill Stoddard]
3519 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3520 routines are now called ap_base64* and are 'plain' (i.e., no
3521 pool access or anything clever). Inside util.c the routines acting
3522 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3523 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3524 now but deprecated. [dirkx]
3526 *) Clean up the base64 and SHA1 additions and make sure they are
3527 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3528 files. [Roy Fielding]
3530 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3531 checking. Allow compiling on VS 6.0. [Randy Terbush]
3533 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3535 *) Use TestCompile to search for the truerand library (rather than blindly
3536 assuming its existence). If it is not found, complain (but do not
3537 exit - yet). [Martin Kraemer]
3539 *) We forgot to add the new exported function names to
3540 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3542 *) Add description of -T command-line option to usage().
3543 [Ralf S. Engelschall]
3545 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3546 searched only AFTER libap has been searched, because libap needs
3547 some symbols from libos. [Martin Kraemer]
3549 *) Fix conflict with original mod_digest related to the symbol of the
3550 module dispatch list (which has to be unique for DSO and follow the
3551 usual conventions for the installation procedure).
3552 [Ralf S. Engelschall]
3554 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3555 for other platforms as well. [Martin Kraemer]
3557 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3558 types by AP_LONG and replace reference to renamed variable 'ubuf'
3559 by 'buffer'. [Martin Kraemer]
3561 Changes with Apache 1.3.8 [not released]
3563 *) Flush the output buffer immediately after sending an error or redirect
3564 response, since the result may be needed by the client to abort a
3565 long data transfer or restart a series of pipelined requests.
3566 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3568 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3569 [Ian Turner <iant@sequent.com>] PR#4735
3571 *) Local struct mmap in http_core.c conflicted with system structure
3572 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3574 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3575 [Ronald Tschalär <ronald@innovation.ch>]
3577 *) Fix a memory leak where the module counts were getting messed
3578 up across restarts. [David Harris <dharris@drh.net>]
3580 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3581 properly in mod_access.
3582 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3584 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3585 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3587 *) PORT: Support for compaq/tandem/com.
3588 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3590 *) Added SHA1 password encryption support to easy migration from
3591 Netscape servers. See support/SHA1 for more information.
3592 Caused the separation of ap_md5.c into md5, sha1 and a general
3593 ap_checkpass.c with just a validate_passwd routine. Added a
3594 couple of flags to support/htpasswd. Some reuse of the to64()
3595 function; hence renamed to ap_to64().
3596 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3598 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3599 with ASCII/EBCDIC conversions in "ident" query.
3600 [David McCreedy <McCreedy@us.ibm.com>]
3602 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3603 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3604 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3606 *) Fix SIGSEGV on some systems because the Vary fix below included
3607 a call to table_do with a variable argument list that was not
3608 NULL terminated. Replaced with better implementation. [Roy Fielding]
3610 Changes with Apache 1.3.7 [not released]
3612 *) The "Vary" response header field is now sanitised right before
3613 the header is sent back to the client. Multiple "Vary" fields
3614 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3615 "Vary: host, negotiate, host, accept-language") are reduced to
3616 single instances. This is a better solution than the force-no-vary
3617 one (which is still valid for clients that can't cope with Vary
3618 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3620 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3622 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3623 least on Linux and FreeBSD for now.
3626 *) Win32: More apache -k restart work. Restarts are now honored
3627 immediately and connections in the listen queue are -not- lost.
3628 This is made possible by the use of the WSADuplicateSocket()
3629 call. The listeners are opened in the parent, duplicated, then
3630 the duplicates are passed to the child. The original listen sockets
3631 are not closed by the parent across a restart, thus the listen queue
3633 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3635 *) Fix handling of case when a client has sent "Expect: 100-continue"
3636 and we are going to respond with an error, but get stuck waiting to
3637 discard the body in the pointless hope of preserving the connection.
3638 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3640 *) Fix 'configure' to work correctly with SysV-based versions of
3641 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3643 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3644 built-in values. Add "-e" option which works like -i but doesn't
3645 install the DSO; useful for editing httpd.conf with apxs. Fix
3646 editing code so that multiple invocations of apxs -a will not
3647 create duplicate LoadModule/AddModule entries; apxs can now be
3648 used to re- enable/disable a module. [Wilfredo Sanchez]
3650 *) Win32: Update the server to use Winsock 2. Specifically, link with
3651 ws2_32.lib rather than wsock32.lib. This gives us access to
3652 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3653 Win 95 users may need to update their TCP/IP stack to pick up
3654 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3655 [Bill Stoddard stoddard@raleigh.ibm.com]
3657 *) Win32: Redirect CGI script stderr (script debug info) into the
3658 error.log when CGI scripts fail. This makes Apache on Win32
3659 behave more like Unix.
3660 [Bill Stoddard stoddard@raleigh.ibm.com]
3662 *) Fixed `httpd' usage display: -D was missing.
3663 [Ralf S. Engelschall] PR#4614
3665 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3666 [Ralf S. Engelschall] PR#4561, PR#4562
3668 *) OS/2: Fix problem with accept lock semaphores where server would die with
3669 "OS2SEM: Error 105 getting accept lock. Exiting!"
3670 [Brian Havard] PR#4505
3672 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3673 [Randy Terbush <randy@covalent.net>]
3675 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3676 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3678 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3679 command potentially _is_ GCC. [Ralf S. Engelschall]
3681 *) Fix apxs build issues on AIX
3682 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3684 *) DocumentRoot Checking: Under previous versions, when Apache
3685 first started up, it used to do a stat of each DocumentRoot to
3686 see if it existed and was a directory. If not, then an error
3687 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3688 does not exist, you will get error messages in error_log. If
3689 the '-t' command line option is used (to check the configuration)
3690 the check of DocumentRoot IS performed. An additional command
3691 line option, '-T', has been added if you want to avoid the
3692 DocumentRoot check even when checking the configuration.
3695 *) Win32: The query switch "apache -S" didn't exit after showing the
3696 vhost settings. That was inconsistent with the other query functions.
3697 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3699 *) Win32: Changed behaviour of apache -k restart.
3700 Previously, the server would drain all connections in the stack's
3701 listen queue before honoring the restart. On a busy server, this
3702 could take hours. Now, a restart is honored almost immediately.
3703 All connections in Apache's queues are handled but connections in
3704 the stack's listen queue are discarded. Restart triggered by
3705 MaxRequestPerChild is unchanged.
3706 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3708 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3709 the accept loop. Good for a 5% performance boost. Cleaned up
3710 parent/child process management code.
3711 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3713 *) Added ceiling on file size for memory mapped files.
3714 [John Giannandrea <jg@meer.net>] PR#4122
3716 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3717 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3718 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3720 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3721 use this at least for Expat. [Ralf S. Engelschall]
3723 *) Allow .module files to specify libraries with Lib:.
3726 *) Allow SetEnvIf[NoCase] to test environment variables as well
3727 as header fields and request attributes. [Ken Coar]
3729 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3730 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3732 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3733 never accepted into any standard, and it opens up certain DoS
3734 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3736 *) TestCompile updated. We can now run programs and output the
3737 results during the Configure process. [ Jim Jagielski]
3739 *) The source is now quad (long long) aware as needed. Specifically,
3740 the Configure process determines the correct size of off_t and
3741 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3742 provides for the 'q' format qualifier (if quads are not available,
3743 'q' is silently "demoted" to long). [Jim Jagielski]
3745 *) When the username or password fed to htpasswd is too long, include the
3746 size limit in the error message. Also report illegal characters
3747 (currently only ':') in the username. Add the size restrictions
3748 to the man page. [Ken Coar]
3750 *) Fixed the configure --without-support option so it doesn't result in
3751 an infinite loop. [Marc Slemko]
3753 *) Piped error logs could cause a segfault if an error occured
3754 during configuration after a restart.
3755 [Aidan Cully <aidan@panix.com>] PR#4456
3757 *) If a "Location" field was stored in r->err_headers_out rather
3758 than r->headers_out, redirect processing wouldn't find it and
3759 the server would core dump on ap_escape_html(NULL). Check both
3760 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3761 if Location isn't set. [Doug MacEachern, Ken Coar]
3763 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3764 of the Expat 1.0.2 distribution. [Greg Stein]
3766 *) Replace regexec() calls with calls to a new API stub function
3767 ap_regexec(). This solves problems with DSO modules which use the regex
3768 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3770 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3771 environment variables can be set according to the protocol version
3772 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3774 *) Add DSO support for OpenStep (Mach 4.2) platform.
3775 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3777 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3778 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3780 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3781 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3783 *) Better DSO flags recognition on NetBSD platforms using ELF.
3784 [Todd Vierling <tv@pobox.com>] PR#4310
3786 *) Always log months in english format for %t in mod_log_config.
3787 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3789 *) Support for server-parsed and multiview-determined ReadmeName and
3790 HeaderName files in mod_autoindex. Removed the restriction on
3791 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3792 routines will deal with the access issues. (It's now possible to
3793 have {site|group|project|customer|...} wide readmes and headers.)
3794 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3797 *) When stat() fails, don't assume anything about the contents of
3798 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3800 *) It's OK for a semop to return EINTR, just loop around and try
3801 again. [Dean Gaudet]
3803 *) Fix configuration engine re-entrant hangups, which solve a
3804 handful of problems seen with mod_perl <Perl> configuration sections
3805 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3807 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3808 by default when building with APACI; allow for platform-specific
3809 variable defaults in configure. [Wilfredo Sanchez]
3811 *) Do setgid() before initgroups() in http_main; some platforms
3812 zap the grouplist when setgid() is called. This was fixed in
3813 suexec earlier, but the main httpd code missed the change.
3814 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3816 *) Add recognition of .tgz as a gzipped tarchive.
3817 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3819 *) mod_include's fsize/flastmod should allow only relative paths, just
3820 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3822 *) OS/2: Add support for building loadable modules using DLLs.
3825 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3828 *) Fix minor but annoying bug with the test for Configuration.tmpl
3829 being newer than Configuration so that it is less likely to fail
3830 when using APACI and shadow sources. [Wilfredo Sanchez]
3832 *) PORT: Add initial support for Mac OS (versions 10.0 and
3833 greater). Use Mac OS X Server layout for now. Clean up dyld code
3834 in unix/os.c, and don't install the dyld error handlers, which
3835 are no longer needed in Mac OS. [Wilfredo Sanchez]
3837 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3838 locations to appropriate ones for user-built (as opposed to
3839 system) installs. [Wilfredo Sanchez]
3841 *) Modify mod_autoindex's handling of AddDescription so that the
3842 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3844 *) Add functionality to the install-bindist.sh script created by
3845 binbuild.sh to use tar when copying distribution files to the
3846 serverroot. This allows upgrading an existing installation
3847 without nesting the new distribution in the old.
3849 install-bindist.sh now detects the local perl5 path to install
3850 apxs and dbmmanage with proper path to perl interpreter.
3852 Add an install-binsupport target which copies the source files
3853 for apxs and dbmmanage to bindist to allow these scripts to
3854 be properly installed relative to the destination serverroot.
3855 [Randy Terbush, Covalent Technologies, randy@covalent.net]
3857 *) Fix intermittent SEGV in ap_proxy_cache_error() in
3858 src/modules/proxy_util.c where a NULL filepointer and

3869 *) Force the LANG envariable to the known state of "C" so that we
3870 have assurance about how string manipulators (e.g., tr) will
3871 function. [Ken Coar] PR#1630
3873 *) Add a directive to allow customising of the tracking cookie name.
3874 [Ken Coar] PR#2921, 4303
3876 *) Add "force-no-vary" envariable to allow servers to work around
3877 clients that choke on "Vary" fields in the response header.
3878 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
3880 *) Fixed a bug in mod_dir that causes a child process will infinitely
3881 recurse when it attemps to handle a request for a directory wnd the
3882 value of the DirectoryIndex directive is a single dot. Also likely
3883 to happen for anyother values of DirectoryIndex that will map back

3967 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
3970 *) Correct an apparent typo: on the Windows and MPE platforms, the
3971 htpasswd utility was limiting passwords to only 8 characters.
3974 *) EBCDIC platforms: David submitted patches for two bugs in the
3975 MD5 digest port for EBCDIC machines:
3976 a) the htdigest utility overwrote the old contents of the digest file
3977 b) the Content-MD5 header value (ContentDigest directive) was wrong
3978 when the returned file was not converted from EBCDIC, but was a
3979 binary (e.g., image file) in the first place.
3980 [David McCreedy <mccreedy@us.ibm.com>]
3982 *) support/htpasswd now permits the password to be specified on the
3983 command line with the '-b' switch. This is useful when passwords
3984 need to be maintained by scripts -- particularly in the Win32
3985 environment. [Ken Coar]
3987 *) Win32: Win32 multiple services patch. Added capability to install and
3988 run multiple copies of apache as individual services.
3991 apache -n apache1 -i -f c:/httpd.conf
3992 Installs apache as service 'apache1' and associates c:/httpd.conf
3995 Starts apache1 service.
3997 Stops apache1 service
4000 apache -n apache2 -i
4001 Installs apache as service 'apache2'. httpd.conf is located under
4002 the default server root (/apache/conf/httpd.conf).
4004 Starts apache2 service.
4007 apache -n apache3 -i -d c:/program files/apache
4008 Install apache as service 'apache3' and sets server root to
4009 c:/program files/apache.
4012 apache -n apache2 -k restart
4013 Restart apache2 service
4015 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
4017 *) Correct the signed/unsigned character handling for the MD5 routines;
4018 mismatches were causing compilation problems with gcc -pedantic and
4019 in the TPF cross-compilation. [Ken Coar]
4021 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
4022 a roughly 5 fold speed up. [Brian Havard]
4024 *) proxy ftp: instead of using the hardwired string "text/plain" as
4025 a fallback type for files served by the ftp proxy, use the
4026 ap_default_type() function to determine the configured type.
4027 This allows for special configurations like
4028 <Directory proxy:ftp://some.host>
4029 DefaultType gargle/blurb
4031 Additionally, add the Content-Encoding: header to FTP proxy replies
4032 when the encoding is defined (by the AddEncoding directive).
4033 Because it was missing, it was almost impossible to browse compressed
4034 files using the FTP proxy (works now perfectly in Communicator).
4035 The ftp proxy now also returns the Date: and Server: header lines (if not
4036 much else... This code is "somewhat" broken) like normal requests do.
4039 *) Be more smart in APACI's configure script when determining the UID/GID
4040 for User/Group directives and use the determined UID/GID to initialize
4041 the permissions on the proxycachedir.
4042 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4044 *) Changed the forking-prior-to-cleanup in the proxy module to first
4045 check wether it actually needs to collect garbage. This reduces
4046 the number of fork()s from one/request to just the odd one an hour.
4047 [Dirk-Willem van Gulik]
4049 *) Added proxy, auth and header support to src/support/ab.c. Added a
4050 README file to src/support/
4051 [Dirk-Willem van Gulik]
4053 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
4054 [Ralf S. Engelschall] PR#4050
4056 *) Add support for DSO module compilation on BSD/OS 3.x.
4057 [Randy Terbush, Covalent Technologies]
4059 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
4060 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
4061 option) were substituted with $(TARGET).conf, etc. Same for other strings
4062 with dots where the dot wasn't matched as plain text.
4063 [Ralf S. Engelschall]
4065 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
4067 *) Fix verbose output of APACI configure (option -v)
4068 [Martin Kraemer, Ralf S. Engelschall]
4070 Changes with Apache 1.3.6
4072 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
4074 Changes with Apache 1.3.5 [not released]
4076 *) M_INVALID needed a value within the scope of METHODS so that unknown
4077 methods can be access controlled. [Roy Fielding] PR#3821
4079 *) Added PassAllEnv; makes server's entire environment available
4080 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4082 *) ap_uuencode() always added two trailing '='s and encoding of
4083 8 bit characters on a machine with signed char may produced
4084 incorrect results. Additionally ap_uuencode() should now
4085 work correctly on EBCDIC platforms.
4086 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4088 *) WIN32: Binary installer now runs the configuration DLL before
4089 the reboot prompt (which is only given if MSVCRT.DLL system
4090 DLL is new or updated). This should avoid the configuration
4091 directory being empty after installation. [Paul Sutton]
4092 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
4094 *) WIN32: Binary installer now creates Start menu options to start
4095 and stop Apache as a console application and to uninstall
4096 the Apache service on NT. [Paul Sutton] PR#3741
4098 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
4100 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
4101 have been reported with flock() locking (probably related to kernel
4102 version). [Dean Gaudet] PR#2723, 3531
4104 *) Using APACI, the main config file (usually httpd.conf) was
4105 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
4106 <wsanchez@apple.com>]
4108 *) PORT: AIX does not require the SHARED_CODE "hack"
4109 [Ryan Bloom <rbb@raleigh.ibm.com>]
4111 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
4112 avoidance code added in 1.3.3.
4113 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
4115 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4116 for 8-bit safeness. [Dean Gaudet]
4118 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4119 because SPARCs have a small machine-specific maximum size for the Global
4120 Offset Table which is often exceeded when compiling one of the larger
4121 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4123 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
4124 DSO/DLL section because it's a directive from mod_status and isn't
4125 available before the DLL of mod_status is loaded.
4126 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
4128 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
4129 continuation facility in Apache's configuration files which could
4130 lead to a buffer overflow situation.
4131 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
4133 *) Make documentation and error messages of APACI's --activate-module=FILE
4134 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995
4136 *) Fix the gcc version check (for enabling the `inline' facility) to
4137 really support all future gcc versions >= 2.7 until we know more.
4138 [John Tobey <jtobey@banta-im.com>] PR#3983
4140 *) Let APACI's configure script correctly complain for unknown --enable-XXX
4141 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
4143 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
4144 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
4145 possible buffer overflows. [Ralf S. Engelschall]
4147 *) Remove no longer used non-API function ap_single_module_init().
4148 [Ralf S. Engelschall]
4150 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4153 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4154 to make platform installations easier. [Wilfredo Sanchez]
4156 *) In configure, do not append the target name to the directory path if
4157 the path already contains "apache". [Ralf S. Engelschall]
4159 *) SIGPIPE is now ignored by the server core. The request write routines
4160 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4161 correctly check for output errors and mark the connection as aborted.
4162 Replaced many direct (unchecked) calls to ap_b* routines with the
4163 analogous ap_r* calls. [Roy Fielding]
4165 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4166 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4167 Furthermore map lookups for non-existent keys are now cached as well.
4168 Additionally "txt" maps are now parsed with simple string functions
4169 instead of using ap_pregcomp(). As a side effect a bug that prevented
4170 the usage of keys containing the "," character was fixed.
4171 The changes drastically improve the performance when large rewrite maps
4173 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4175 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4176 other than GET, and const'd the definition of method in request_rec.
4179 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
4181 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4182 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4184 *) Add %V to mod_log_config, this logs the hostname according to the
4185 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4186 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4188 *) Add support for \n and \t to mod_log_config, can be used to produce
4189 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4191 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4193 *) Added informative error messages for failed munmap() and fseek() calls
4194 in http_core.c. [John Bley, Roy Fielding]
4196 *) Added some informative error messages for some failed malloc()
4197 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4199 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4200 is removed. This allows <Directory proxy:*> directives to work and
4201 prevents invalid requests from killing the process.
4202 [Brian Havard <brianh@kheldar.apana.org.au>]
4204 *) Reorganised FAQ document.
4205 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
4207 *) src/support/: The ApacheBench benchmark program was overhauled by
4208 David N. Welton: you can now have it generate an HTML TABLE, presumably
4209 for integration into other HTML sources. David updated the ab man page
4210 as well and added some missing descriptions. Thanks!
4211 [David N. Welton <davidw@prosa.it>]
4213 *) Win32: The filename validity checker now allows filenames containing
4214 characters in the range 0x80 to 0xff (for example accented characters).
4215 [Paul Sutton] PR#3890
4217 *) Added conditional logging based upon environment variables to
4218 mod_log_config. mod_log_referer and mod_log_agent
4219 are now deprecated. [Ken Coar]
4221 *) Allow apache acting as a proxy server to relay the real
4222 reason of a failure to a client rather than the "internal
4223 server error" it does currently. The general exposure mechanism
4224 can be triggered by any module by setting the "verbose-error-to"
4225 note to "*"; this allows more than just proxy errors to be exposed.
4226 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4228 *) Moved man pages for ab and apachectrl to section 8.
4229 [Wilfredo Sanchez, Roy Fielding]
4231 *) Added -S option to install.sh so that options can be passed to
4232 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4234 *) Tweak modules Makefile generated by Configure so that it handles
4235 the test case of no modules being selected. [chaz@reliant.com]
4237 *) Added a <LimitExcept method ...> sectioning directive that allows
4238 the user to assign authentication control to any HTTP method that
4239 is *not* given in the argument list; i.e., the logical negation
4240 of the <Limit> directive. This is particularly useful for controlling
4241 access on methods unknown to the Apache core, but perhaps known by
4242 some module or CGI script. [Roy Fielding, Tony Finch]
4244 *) Prevent apachectl from complaining if the PIDFILE exists but
4245 does not contain a process id, as might occur if the server is
4246 being rapidly restarted. [Wilfredo Sanchez]
4248 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4250 *) Entity tag comparisons for If-Match and If-None-Match were not being
4251 performed correctly -- weak tags might cause false positives. Also,
4252 strong comparison wasn't properly enforced in all cases.
4253 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4255 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4258 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4259 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4261 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4262 to util.c for parsing an HTTP header field value to extract the next
4263 list item, taking into account the possible presence of nested comments,
4264 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4265 insignificant whitespace and lowercases non-quoted tokens.
4266 [Roy Fielding] PR#2065
4268 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4269 code different from 500. This allows the proxy to, e.g., return
4270 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4272 *) Fix ordering of language variants for the case where the traditional
4273 negotiation algorithm is being used with multiple language variants
4274 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4276 *) Do not round the TCN quality calculation to 5 decimal places,
4277 unlike RFC 2296, because the calculation might need 12 decimal places
4278 to get the right result. [Roy Fielding]
4280 *) Remove unused code to disable transparent negotiation when
4281 negotiating on encoding only, as we now handle encoding too
4282 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4283 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4284 some debugging statements within mod_negotiation. [Koen Holtman]
4286 *) Fixed a rare memory corruption possibility in mod_dir if the index
4287 file is negotiable and no acceptable variant can be found.
4288 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4290 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4291 searching the Win32 registry for script interpreters.
4294 *) Win32: The compiled-in default filename for the error log is now
4295 error.log, which matches the default in the distributed httpd.conf.
4298 *) Win32: Any error messages from -i or -u command line options are now
4299 displayed on the console output rather than sent to the error log.
4300 Also the "Running Apache..." message is not output unless Apache is
4301 going to serve requests. [Paul Sutton]
4303 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4304 and use a private significator ('$apr1$') to mark passwords as
4305 being smashed with our own algorithm. Also abstract the password
4306 checking into a new ap_validate_password() routine. [Ken Coar]
4308 *) Win32: The filename validity checker now allows "COM" but refuses
4309 access to "COM1" through "COM4". This allows filenames such
4310 as "com.name" to be served. [Paul Sutton] PR#3769.
4312 *) BS2000: Adapt to the new ufork() system call interface which will
4313 make subtasking easier on the OSD/POSIX mainframe environment.
4316 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4317 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4319 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4320 use `.db' instead of `.pag' not only for FreeBSD, but also when
4321 the NDBM library looks like Berkeley-DB based.
4322 [Ralf S. Engelschall] PR#3773
4324 *) Add ability to handle DES or MD5 authentication passwords.
4325 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4327 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4329 *) SECURITY: Avoid some buffer overflow problems when escaping
4330 quoted strings. (This overflow was on the heap and we believe
4331 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4333 *) Let src/Configure be aware of CFLAGS options starting with plus
4334 signs as it's the case for the HP/UX compiler.
4335 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4337 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4338 and check to see if the tar we wind up with supports '-h'.
4339 [Jim Jagielski] PR#3671
4341 *) A consistent and conservative style for all shell scripts has been
4342 implemented. Basically, all shell string tests use the traditional
4343 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4344 to protect against bare null variable strings (ie: wrapping both
4345 sides with double quotes and prepending 'x'). 'x' was chosen
4346 because it's more universal and hopefully easier for old shell
4347 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4350 *) The status module now prints out both the main server generation as
4351 well as the generation of each process. Also, the vhost info is
4352 printed with '?notable'. [Jim Jagielski]
4354 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4355 and this makes its functions available to things in src/support.
4358 Changes with Apache 1.3.4
4360 *) Renamed macros status_drops_connection to ap_status_drops_connection
4361 and vestigial scan_script_header to ap_scan_script_header_err,
4362 mostly for aesthetic reasons. [Roy Fielding]
4364 *) The query switch "httpd -S" didn't exit after showing the
4365 vhost settings. That was inconsistent with the other query functions.
4368 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4369 filename to the end of the STANDARD_MODULE_STUFF. Its
4370 presence at the beginning prevented reporting of the filename
4371 for modules compiled before 1 January 1999. [Ken Coar]
4373 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4374 to detect and prevent access to special DOS device file names.
4375 [Paul Sutton, Ken Parzygnat]
4377 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4378 and Makefile_win32_debug.txt (debug build) that work on Win95.
4379 Run each of the following from the src directory:
4380 nmake /f Makefile_win32.txt # compiles normal build
4381 nmake /f Makefile_win32.txt install # compiles and installs
4382 nmake /f Makefile_win32.txt clean # removes compiled junk
4383 nmake /f Makefile_win32_debug.txt # compiles debug build
4384 nmake /f Makefile_win32_debug.txt install
4385 nmake /f Makefile_win32_debug.txt clean
4388 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4389 to build binary distributions. [Lars Eilebrecht]
4391 *) IndexOptions SuppressColumnSorting only turned off making
4392 the column headers anchors; you could still change the display
4393 order by manually adding a '?N=A' or similar query string to the
4394 URL. Now SuppressColumnSorting locks in the sort order so
4395 it can't be overridden this way. [Ken Coar]
4397 *) Added IndexOrderDefault directive to supply a default sort order
4398 for FancyIndexed directory listings. [Ken Coar] PR#1699
4400 *) Change the ap_assert macro to a variant that works on all platforms.
4401 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4403 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4404 search for an underscore on dlsym() (as it's already the case
4405 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4407 *) Small fix for mod_env.html: The module was documented as to be _not_
4408 compiled into Apache per default, although it _IS_ compiled into
4409 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4411 *) Instead of fixing a bug in the generation procedure for config.status (a
4412 backslash was missing) we remove the bug together with it's complete
4413 context because the special cases of the past can now no longer occur
4414 because of the recent magic for the --with-layout default.
4415 [Ralf S. Engelschall] PR#3590
4417 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4418 making sure the src/support/ tools are _forced_ to be build last (they
4419 depend on other libraries).
4420 [Markus Theissinger <markus.theissinger@gmx.de>]
4422 *) Fix installation procedure: Now that os-inline.c is actually used (a
4423 recently fixed bug prevented this) we need to also install os-include.c
4424 in addition to os.h into the PREFIX/include/ location or building of
4425 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4427 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4428 allow us to distinguish between a garbled DSO (or even a file which isn't
4429 an Apache module DSO at all) and a DSO which doesn't match the current
4430 Apache API. [Ralf S. Engelschall] PR#3152
4432 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4433 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4434 match case insensitive (this especially avoids nasty patterns like
4435 `[tT][eE][sS][tT]'). Second two additional internal map functions
4436 `escape' and `unescape' were added which can be used to escape/unescape
4437 to/from hex-encodings in URLs parts (this is especially useful in
4438 combination with map lookups).
4439 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4441 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4442 forgotten (because it was a macro) in the symbol renaming process.
4443 [Ralf S. Engelschall]
4445 *) Fix some inconsistencies related to the scopes of directives. The only
4446 user visible change is that the directives `UseCanonicalName' and
4447 `ContentDigest' now use the (more correct) `Options' scope instead of
4448 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4450 *) Using DSO, the Server token was being mangled. Specifically, the
4451 module's token was being added first before the Apache token. This
4452 has been fixed. [Jim Jagielski]
4454 *) Major overhaul of mod_negotiation.c, part 2.
4455 - properly handle "identity" within Accept-Encoding.
4456 - allow encoded variants in RVSA negotiation and let them appear in
4457 the Alternates field using the non-standard "encoding" tag-list.
4458 - fixed both negotiation algorithms so that an explicitly accepted
4459 encoding is preferred over no encoding if "identity" is not
4460 included within Accept-Encoding.
4461 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4462 of large substring sequences.
4463 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4466 *) Major overhaul of mod_negotiation.c, part 1.
4467 - cleanups to mod_negotiation comments and code structure
4468 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4469 support for everything in the upcoming HTTP/1.1
4470 revision (draft-ietf-http-v11-spec-rev-06.txt).
4471 - language tag matching also handles tags with more than 2
4473 - empty Accept, Accept-Language, Accept-Charset headers are

4475 values acceptable instead of unacceptable.
4476 - allowed for q values in Accept-Encoding
4477 - added support for transparent content negotiation (rfc2295 and
4478 rfc2296) (though we do not implement all features in these drafts,
4479 e.g. no feature negotiation). Removed old experimental version.
4480 - implemented 'structured entity tags' for better cache correctness
4481 (structured entity tags ensure that caches which can deal with Vary

4484 - this involved adding a vlist_validator element to request_rec
4485 - this involved adding the ap_make_etag() function to the global API
4486 - modified guessing of charsets used by Apache negotiation algorithm
4487 to guess 'no charset' if the variant is not a text/* type
4488 - added code to sort multiviews variants into a canonical order so that

4521 *) Update APXS manual page: some -q option arguments were missing
4522 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4524 *) Cleanup the command line options: `-?' was documented to show
4525 the usage list but does it with an error because `?' is not a valid
4526 command. OTOH a lot of users expect `-h' to print such a usage list and
4527 instead are annoyed for ages by our huge unreadable list of directives.
4528 So we now changed the command line options this way:
4530 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4531 very similar to the popular linker option.
4533 Intent: while -l gives the small list of modules, -L now gives the
4534 large list of directives implemented by these modules. This is also
4535 consistent with -v (short version info) and -V (large version info).
4537 Intent: it's now the expected option ;-)
4538 The manual page was adjusted accordingly.

4542 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4544 *) Removed recently introduced bugs and disfigurements in APACI:
4545 o fixed argument line processing: using $args was broken: It was not
4546 initialized and using args="$args $apc_option" and even args="$args
4547 \"$apc_option\"" fails in the second processing round for any arguments
4548 containing whitespaces. The only correct way is to use the construct
4549 "$@" (but not possible here) or iterate _both_ times over the implicit
4550 argument line (no argument to for-loop) which is what we now use.
4551 o make --with-layout=Apache the default without creating
4552 redundancy (copying the --with-layout block in the argument parsing
4553 loop). We achieve this by using the "$@" construct together with the
4554 `set' command to prepend --with-layout=Apache to the command line in
4555 case --with-layout is not used.
4556 o fixed auto-suffix handling now that config.layout exists.
4557 Paths which are auto-suffixed are marked with a trailing plus sign in
4558 config.layout and every path now can be marked this way (not only the
4559 four paths for which we do it currently). Additionally the suffix is
4560 no longer a static one. Instead it's now `/<target>' where <target> is
4561 the argument of the --target option or per default `httpd'.
4562 o allow also tabs (and only spaces) where we match whitespaces
4563 o various fixes and cleanups related to used shell coding style
4564 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4565 o trimmed output of --help to fit into 80 columns

4632 identifier, currently "Apache" and "GNU" are pre-defined in the file
4633 config.layout. Custom layouts are possible by using FILE:ID as the
4634 argument where the layout ID is taken from FILE.
4636 The config.layout file consists of <Layout ID>..</Layout> sections
4637 where inside those sections "path_variable: path_value" pairs can be
4638 specified. These lines are converted to path_variable='path_value'.
4640 *) Add a DefaultLanguage directive so that files missing a language
4641 extension (e.g., .fr, .de) can be labelled as being some other

4959 and to avoid problems under platforms where only version 2.x is present.
4960 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
4962 *) When using ap_log_rerror(), make the error message available to the
4963 *ERROR_NOTES envariables by default. [Ken Coar]
4965 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
4966 You now must define a BS2000Account name for the server User.
4967 This has fewer security implications than the old approach.
4970 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4971 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4972 platform to make the braindead HPUX linker happy. Notice, for the module
4973 DSOs we don't have to use this, because these are loaded manually (and
4974 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

4985 *) Make PrintPath work generically instead of having one version
4986 strictly for OS/2. [Jim Jagielski, Brian Havard]
4988 *) Fix the recently introduced C header file checking: We now use the C
4989 pre-processor pass only (and no longer the complete compiler pass) to
4990 determine whether a C header file exists or not. Because only this way
4991 we're safe against inter-header dependencies (which caused horrible
4992 portability problems). The only drawback is that we now have a CPP
4993 configuration variable which has to be determined first (we do a similar
4994 approach as GNU Autoconf does here). When all fails the user still has
4995 the possibility to override it manually via APACI or src/Configuration.
4996 As a fallback for the header check itself we can directly check the
4997 existance of the file under /usr/include, too.

5046 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
5048 *) mod_expires will now act on content that is not sent from a file

5068 a common problem of (mis-administrated?) IIS servers, make the apache
5069 proxy immune to these errors (and ignore the duplicates, but log
5070 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
5072 *) The <IfModule and <IfDefine block starting directives now only
5073 allow exactly one argument. Previously, the optional negation
5074 character '!' could be separated by whitespace without a syntax
5075 error being reported, albeit defeating the IfModule functionality
5076 (enclosed directives would ALWAYS be executed). By using the
5077 stricter syntax, these hard-to-track errors can be avoided.
5080 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
5081 cause the standalone FancyIndexing directive to logically OR
5082 into any existing IndexOptions settings rather than wiping
5083 them out. [Ken Coar]
5085 *) Changes in ftp proxy: make URL parsing simpler by using the
5087 + Add display of the "current directory" in cases where it's
5088 different from the supplied path (e.g., ftp://user@host/ lives
5089 in /home/user, not in /, therefore clicking on "../" in the
5090 starting directory might send us to /home/).
5091 + When ftp login fails, (esp. when a user name was part of the
5092 URL already), we now return [401 Unauthorized ] to allow the
5093 browser to pop up an authorization dialog. This makes passwords
5094 slightly less visible (they don't appear in the regular log files)
5095 and implements a functionality that other www proxy servers
5099 *) Triggered by the recent "Via:" header changes, the proxy module would
5100 dump core for replies with invalid headers (e.g., duplicate
5101 "HTTP/1.0 200 OK" lines). These errors are now logged and the
5102 core dump is avoided. Also, broken replies are not cached.

5167 vhost, request and client information is not displayed.
5170 *) STATUS is no longer available. Full status information now
5171 run-time configurable using the ExtendedStatus directive.
5174 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
5175 cpu time attacks) in header parsing. Add ap_overlap_tables(),
5176 a function which can be used to perform bulk update operations
5177 on tables in a more efficient manner. [Dean Gaudet]
5179 *) SECURITY: Added compile-time and configurable limits for
5180 various aspects of reading a client request to avoid some simple
5181 denial of service attacks, including limits on maximum request-line
5182 size (LimitRequestLine), number of header fields (LimitRequestFields),
5183 and size of any one header field (LimitRequestFieldsize). Also added

5231 [Brian Havard, Ralf S. Engelschall]
5233 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
5234 files (here modules) against other DSO files (here shared libraries).
5235 This is done by determining a subset of LIBS which can be safely used for
5236 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
5237 disabled for all platforms to avoid problems with this (experimental)

5459 used instead of "$PERL" which contains the correctly determined Perl
5460 interpreter (important for instance on systems where "perl" and "perl5"
5461 exists, like BSDI or FreeBSD, etc).
5462 [Ralf S. Engelschall] PR#2505
5464 *) Move the initial suEXEC-related startup message from plain
5465 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
5466 when Apache is started from inetd (instead of standalone). Under this
5467 situation startup messages on stderr lead to problems (the line is sent
5468 to the client in front of the requested document).

5483 *) PORT: remove broken test for MAP_FILE in http_main.c.
5484 [Wilfredo Sanchez <wsanchez@apple.com>]
5486 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
5487 httpd is running. This should be more portable than figuring out
5488 which of three dozen different versions of "ps" are installed.
5491 *) WIN32: If we can't figure out how to execute a file in a script
5492 directory, bail out of the request with an error message. [W G Stoddard]
5494 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
5495 these are treated by Win32 as if they are ".." but are not detected by
5496 other machinery within Apache. This is something of a kludge but
5497 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5499 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5500 pools and thus pollutes libap (until the pool stuff is moved there).
5503 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
5504 but case-insensitive platforms). New #define for this added to conf.h
5505 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455

5511 [Sam Kington <sam@illuminated.co.uk>] PR#2443
5513 *) Let APACI's configure script determine some configuration parameters
5514 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5515 remove some of the classical hurdles for new users when setting up
5516 Apache. This is done per default because it is useful for the average
5517 user. Package authors can use the --without-confadjust option to disable
5518 these configuration adjustments.
5519 [Ralf S. Engelschall]
5521 *) Added an EXTRA_DEPS configuration parameter which can be used
5522 to add an extra Makefile dependency for the httpd target, for instance
5523 to external third-party libraries, etc.
5524 [Ralf S. Engelschall]
5526 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5527 as <IfModule>..</IfModule> sections) which can be used to skip or process
5528 contained commands dependend of ``-D PARAMETER'' options on the command
5529 line. This can be used to achieve logical conditions like <IfDefine
5530 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5531 and thus especially can be used for conditionally loading DSO-based
5532 modules via LoadModule, etc. [Ralf S. Engelschall]
5534 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
5536 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
5538 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
5539 truncated which forced following HTTP headers to be data in the HTTP
5540 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5543 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5544 in top-level configure script to avoid sed fails on some platforms (for
5545 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5546 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5548 *) Improve performance of directory listings (mod_autoindex) by comparing
5549 integer keys (last-modified and size) as integers rather than converting
5550 them to strings first. Also use a set of explicit byte tests rather
5551 than strcmp() to check for parent directory-ness of an entry. Oh, and
5552 make sure the parent directory (if displayed) is *always* listed first
5553 regardless of the sort key. Overall performance winnage should be good
5554 in CPU time, instruction cache, and memory usage, particularly for large
5555 directories. [Ken Coar]
5557 *) Add a tiny but useful goody to APACI's configure script: The generation
5558 of a config.status script (as GNU Autoconf does) which remembers the used
5559 configure command and hence can be used to restore the configuration by
5560 just re-running this script or for remembering the configuration between
5562 [Ralf S. Engelschall]
5564 *) Add httpd -t (test) option for running configuration syntax tests only.
5565 If something is broken it complains and exits with a return code
5566 non-equal to 0. This can be used manually by the user to check the Apache
5567 configuration after editing and is also automatically used by apachectl
5568 on (graceful) restart command to make sure Apache doesn't die on restarts
5569 because of a configuration which is now broken since the last (re)start.
5570 This way `apachectl restart' can be used inside cronjobs without having
5571 to expect Apache to be falling down. Additionally the httpd -t can be run
5572 via `apachectl configtest'.

5712 spawn_child was obsoleted and moved to compat.h
5715 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5716 programs: ap_spawn_child_err() is used and the Win32 case now uses
5717 CreateProcess() instead of a low-level execl() (which caused problems in
5718 the past under Win32).
5719 [Ralf S. Engelschall]
5721 *) A few cosmetics and trivial enhancements to APXS to make the
5722 generated Makefile more user friendly. [Ralf S. Engelschall]
5724 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5725 was updated to use the normal apache error processing, thereby allowing
5726 proxy errors to be treated by ErrorDocument's as well. For this
5727 purpose, a new module-to-core communication variable "error-notes"
5728 was introduced; the proxy (and possibly other modules) communicates
5729 its error text using this variable. Its content is copied to a new
5730 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5731 The old proxy special error routine ap_proxy_log_uerror()
5732 was replaced by regular ap_log_error() calls, many messages were made

5736 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5739 *) Transform the configure message "You need root privileges for suEXEC"
5740 from a fatal error into a (more friendly) warning because the building
5741 ("make") of Apache we can allow, of course. Root privileges are needed
5742 only for the installation step ("make install"). So make sure the
5743 user is aware of this fact but let him proceed as long as he can.

5804 instead of C file descriptors.
5805 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5807 *) The proxy cache would store an incorrect content-length in the cached
5808 file copy after a cache update. That resulted in repeated fetching
5809 of the original copy instead of using the cached copy.
5810 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5812 *) The Makefiles assumed that DSO files are build via $(LD). This
5813 is broken for two reasons: First we never defined at least LD=ld
5814 somewhere to make sure this works (it was silently assumed that most Make
5815 provide a built-in LD definition - ARGL!) and second using the generic LD
5816 variable is not the truth. Instead a special variable named LD_SHLIB is
5817 reasonable because although "ld" is usually the default, the command for
5818 building DSO files can be "libtool" or even "cc" on some systems.
5819 [Ralf S. Engelschall]
5821 *) Replace the AddVersionPlatform directive with ServerTokens which
5822 provides for more control over the format of the Server:
5823 header line. SERVER_SUBVERSION is no longer supported;
5824 all module should use the ap_add_version_component()
5825 API function instead. [Jim Jagielski]

5831 not retrieved in src/Configure and thus was not useable.
5832 [Ralf S. Engelschall]
5834 *) Various Makefile consistency cleanups:
5835 - make OSDIR also automatically be relative to src/ like INCDIR
5836 - SUBDIRS is now generated in src/Makefile only and not in
5837 Makefile.config because it is a local define for this location.
5838 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5839 any Makefile but make sure that at least the "-K inline" is kept in
5841 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5842 - updated the dependencies theirself
5843 - removed not existing SHLIB variable from "clean" targets
5844 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5845 already exists and OBJS_PIC are also just plain objects and have not
5846 directly to do with "shared" things. The only difference is that they
5847 contain PIC. So OBJS_PIC is the more canonical name.
5848 - Updated the Makefile-dependency lines for OBJS_PIC
5849 - Removed the Makefile-dependency line in Configure to avoid double
5851 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5852 of xxx.lo as GNU libtool does with its PIC objects
5853 - reduce local complexity in modules Makefile.tmpl by moving the last
5854 existing target "depend" to the generation section in Configure, too.
5855 - removed the historical $(SPACER) which was used in the past together
5856 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5857 is no longer needed.
5858 - force the build and run of the gen_xxx programs under main/ as the
5859 first step before building the objects because it looks cleaner
5860 [Ralf S. Engelschall]
5862 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5865 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5868 *) WIN32: Don't force ISAPI headers to finish with \n.
5869 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5871 *) When opening "configuration" files (like httpd.conf, htaccess
5872 and htpasswd), Apache will not allow them to be non-/dev/null
5873 device files. This closes a DoS hole. At the same time,
5874 we use ap_pfopen to open these files to handle timeouts.
5875 [Jim Jagielski, Martin Kraemer]
5877 *) Apache will now log the reason its httpd children exit if they exit
5878 due to an unexpected signal. (It requires a new porting define,
5879 SYS_SIGLIST, which if defined should point to a list of text
5880 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5882 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5883 like WIN32. Before, Win32 CGI's could have had sporadic failures
5884 if a chdir call from one thread was made between another chdir call
5885 and a spawn in another thread. So, for now don't chdir for CGI scripts
5886 in WIN32. The current CGI "spec" is unclear as to whether it's
5887 necessary. Long-term fix is to either serialize the chdir/spawn combo
5888 or use WIN32 native calls to spawn a process. This temp fix was
5889 necessary to remove this as a showstopper for 1.3's release.
5892 *) Cleanup the suEXEC support in APACI and make it more safe:
5893 1. Add big fat hint in INSTALL about risks and to read the
5894 htdocs/manual/suexec.html document before using the suexec-related
5896 2. Make sure the user has at least provided one --suexec-xxxx option
5897 (specifies suEXEC parameters) in addition to --enable-suexec option.
5898 If only --enable-suexec is given APACI stops with a hint to INSTALL
5899 and htdocs/manual/suexec.html documents.
5900 3. Provide two additional --suexec-xxxx options to make the suEXEC
5901 configuration complete (especially for package maintainers who else
5902 had to patch the source tree) by providing ways to configure minimal
5903 UID/GID and safe PATH, too.
5904 [Ralf S. Engelschall]
5906 *) Cleanup of the `configure --shadow' process:
5907 - make sure the configure script creates its temporary files in the
5908 shadow tree to avoid conflicts with parallel configure runs
5909 - removed unnecessary option "-r" from "rm" call for Makefiles
5910 - make sure the configure scripts creates the shadow-wrapper Makefile
5911 only when no shadow trees already exists
5912 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5913 when no more shadow trees exists
5914 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5915 as fast (in the past it needed 70sec, now it runs just 38sec)
5916 - make sure CVS does not complain about the created files
5917 Makefille.<gnutriple> and directories src.<gnutriple>
5918 [Ralf S. Engelschall]
5920 *) Added the ap_add_version_component() API routine and the
5921 AddVersionPlatform core directive. The first allows modules to
5922 declare themselves in the Server response header field value,
5923 augmenting the SERVER_SUBVERSION define in the Configuration file
5924 with run-time settings (more useful in a loadable-module environment).
5925 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5926 into the server version string. [Ken Coar] PR#2056
5928 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5931 *) Emit the "Accept-Range" header for the default handler.
5932 [Brian Behlendorf] PR#1464
5934 *) Add a note to httpd.conf-dist that apache will on some systems fail
5935 to start when the Group # is set to a negative or large positive value.
5938 *) Make sure the module execution order is correct even when some modules
5939 are loaded under runtime (`LoadModule') via the DSO mechanism:
5940 1. The list of loaded modules is now a dynamically allocated one
5941 and not the original statically list from modules.c
5942 2. The loaded modules are now correctly setup by LoadModule for
5943 later use by the AddModule command.
5944 3. When the DSO mechanism for modules is used APACI's `install'
5945 target now enables all created `LoadModule' lines per default because
5946 this is both already expected by the user _and_ needed to avoid
5947 confusion with the next point and reduces the Makefile.tmpl complexity
5948 4. When the DSO mechanism for modules is used, APACI's `install'
5949 target now additionally makes sure the module list is reconstructed
5950 via a complete `ClearModuleList+AddModule...' entry.
5951 5. The support tool `apxs' now also makes sure an AddModule command
5952 is added in addition to the LoadModule command.
5953 6. The modules.c generation was extended to now contain two
5954 comments to make sure no one is confused by the confusing terminology
5955 of loading/linking (we use load=link+load & link=activate instead of
5956 the obvious load=activate & link=link :-( )
5957 This way now there is no longer a difference under execution time between
5958 statically and dynamically linked modules.

5962 Big Symbol Renaming. [Ralf S. Engelschall]
5964 *) Add a comment to mod_example.c showing the format of a FLAG command
5967 *) Standardized the time format in mod_status to match that of other
5968 places in the code (e.g. DATE_GMT). PR#1551
5970 *) Fix handling of %Z in timefmt strings for those platforms with no time
5971 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5974 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5975 feature compatible with 'UseCanonicalName off' by changing
5976 r->server->server_hostname to ap_get_server_name(). And I changed some
5977 functions which use r->server->port to use ap_get_server_port() instead,
5978 because if there's no Port directive in the config r->server->port is 0.
5981 *) get/set_module_config are trivial enough to be better off inline. Worth
5982 1.5% performance boost. [Dean Gaudet]
5984 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5985 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5988 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5989 the task environment to the unprivileged User id. Otherwise CGI scripts
5990 would have a way to gain super user access. [Martin Kraemer]
5992 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5993 absolute path, only log base name of logging source as is done
5994 in unix. [Martin Kraemer]
5996 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5997 the encoding type from the Accept-Encoding header (if it's there)
5998 and use it in the response, as that's probably what it'll be expecting.

6012 of APEXIT_CHILDFATAL) the parent process to abort and
6013 shutdown the server if the error in the child process was
6014 fatal enough. [Jim Jagielski]

6028 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
6029 Additionally the checks for finding the vendor DSO library were moved
6030 from mod_so.c to Configure because first it needs $PLAT etc. and second
6031 mod_so already uses an abstraction layer and does not fiddle with the
6032 vendor functions itself.
6033 [Jens-Uwe Mager, Ralf S. Engelschall]
6035 *) PORT: Some optimization defines for NetBSD
6036 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6038 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6039 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6041 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6042 AIX variants should work fine, too. Even AIX 3.x should work). This is
6043 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6044 which we put into a os/unix/os-dso-aix.c file.
6045 [Ralf S. Engelschall]
6047 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6048 that we should use NET_SIZE_T == int but the include files force size_t.
6049 [Ralf S. Engelschall]
6051 *) Fix two bugs in select() handling in http_main.c.
6054 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6055 is unset (as it is in situations like timeouts) where it is unclear
6056 whether errno is set or not. [Martin Kraemer]
6058 *) Just having APACI's localstatedir is too general and not enough for most
6059 of the systems. 1.3b6 again required manual APACI patches by package
6060 maintainers from RedHat and FreeBSD because for their filesystem layout a
6061 little bit more flexibility in configuring the paths is needed. Hence we
6062 provide three additional configure options (--runtimedir, --logfiledir,
6063 --proxycachedir) which now can be used for more granular adjustments if
6064 --localstatedir is not enough to fit the particular needs. As a nice
6065 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6066 [Ralf S. Engelschall]
6068 *) Make the install root for "make install" in APACI's Makefile overrideable
6069 by package authors. This way we are even more friendly to package
6070 maintainers (especially Debian and RedHat) who build for the real prefix
6071 via "configure --prefix=/<real>" but use a different local prefix via
6072 "make root=/tmp/apache install" for rolling the package without bristling
6073 the target location on their system.
6074 [Ralf S. Engelschall]
6076 *) Workaround sed limitations in APACI's configure script by now
6077 substituting in chunks of 50 commands (because for instance HPUX's vendor
6078 sed has a limit of max. 98 commands)
6079 [Ralf S. Engelschall] PR#2136
6081 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
6082 [Ralf S. Engelschall] PR#2140
6084 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6085 RENAMING process because they are defined as pre-processor macros instead
6086 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6087 [Ralf S. Engelschall]
6089 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6090 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6091 [Ralf S. Engelschall] PR#2139
6093 *) Various bugfixes and cleanups for the APACI configure script:
6094 o fix IFS handling for _nested_ situation
6095 o fix Perl interpreter search: take first one found instead of last one
6096 o fix DSO consistency check
6097 o print error messages to stderr instead of stdout
6098 o add install-quiet for --shadow situation to Makefile stub
6099 o reduce complexity by avoiding sed-hacks for rule and module list loops

6102 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6104 *) Make sure the input field separator (IFS) shell variable is explicitly
6105 initialized correctly before _every_ `for' loop and also restored after
6106 the loops. [Ralf S. Engelschall]
6108 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6109 `magic' files from an existing Apache installation. Because people often
6110 customize these for own MIME and content types.

6117 [Ralf S. Engelschall] PR#2105
6119 *) Let "configure" clear out the users parameters (provided as shell

6121 exported them (which is not needed, but some users do it).
6122 [Ralf S. Engelschall] PR#2101
6124 *) Provide backward compatibility from some old src/Configuration.tmpl
6125 parameter names to the canonical Autoconf-style shell variable names. For

6148 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6150 *) If you start apache with the -S command line option it will dump
6151 out the parsed vhost settings. This is useful for folks trying
6152 to figure out what is wrong with their vhost configuration.
6153 (Other dumps may be added in the future.) [Dean Gaudet]
6155 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6156 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6159 *) Because /usr/local/apache is the default prefix the ``configure
6160 --compat'' option no longer has to set prefix, again. This way the
6161 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6163 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6164 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6165 to avoid "discard const" warnings. [Ralf S. Engelschall]
6167 *) If a specific handler is set for a file yet the request still
6168 ends up being handled by the default handler, log an error
6169 message before handling it. This catches things such as trying
6170 to use SSIs without mod_include enabled. [Marc Slemko]
6172 *) Fix error logging for the startup case where ap_log_error() still uses
6173 stderr as the target. Now the default log level is honored here, too.
6174 [Ralf S. Engelschall]
6176 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
6177 long" errors when generating the MODULES entry for src/Makefile

6180 *) Make sure src/Configure doesn't complain about the old directory
6181 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6183 Changes with Apache 1.3b6
6185 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6187 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6188 interface via the similar but proprietary HP/UX shl_xxx-style system
6189 calls. [Ralf S. Engelschall]
6191 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6192 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6193 Make. [Ralf S. Engelschall]
6195 *) ++++ THE BIG SYMBOL RENAMING ++++
6196 To avoid symbol clashes with third-party code compiled into the server,
6197 we globally applied the prefix "ap_" to the following classes of
6199 - Apache provided general functions (e.g., ap_cpystrn)
6200 - Public API functions (e.g., palloc, bgets)
6201 - Private functions which we can't make static (because of
6202 cross-object usage) but should be (e.g., new_connection)
6203 For backward source compatibility a new header file named compat.h was
6204 created which provides defines for the old symbol names and can be used
6205 by third-party module authors.
6208 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6209 problem under SVR4 is that there is no command flag to force the linker
6210 to export the global symbols of the httpd executable therewith they are
6211 available to the DSO's. Instead of problematic hacks like creating a
6212 dummy.so file (containing dummy references to all global symbols) the
6213 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6214 Placing the Apache core code itself into a DSO library named libhttpd.so.
6215 This way the global symbols _HAVE_ to be exported and thus are available
6216 to any manually loaded DSO's under runtime. To reduce the impact to the
6217 user to null we go even further and create a stub httpd executable which
6218 automatically keeps track of the DSO library loading itself and thus
6219 hides the complete mechanism from the user. Although the generation of
6220 this DSO library is automatically triggered for platforms which
6221 essentially need it (mostly all SVR4-derivates) it can be also enabled
6222 manually via the Rule SHARED_CORE. This can be interesting in the future
6223 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6224 features like graceful upgrades, or whatever.
6225 [Ralf S. Engelschall, Martin Kraemer]
6227 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6229 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6230 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6231 conventions while "clean" removes only stuff created by "all" targets,
6232 "distclean" additionally removes the stuff from the configuration
6233 process. This way "make distclean" (hence the name) provides a fresh
6234 source tree as it was for distribution.
6235 [Ralf S. Engelschall]
6237 *) Allow top-level (APACI) Makefile to break on build errors
6238 the same way the src/ subtree Makefiles breaks on them by replacing the
6239 initial APACI sed-subdir-display-kludge with a more clean
6240 variable-passing-solution: variable SDP can optionally hold the subdir
6241 prefix which is consistently used for displaying the subdir movement.
6242 This way even the top-level Makefile can stop correctly on errors as the
6243 user expects. [Ralf S. Engelschall]
6245 *) Fixed ordering of argument checks for RewriteBase directive.
6246 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6248 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6249 indicating that a module is being compiled for dynamic loading. Also
6250 remove #define IS_MODULE from modules and add SHARED_MODULE define
6251 to the mak/dsp files. [Alexei Kosut]
6253 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6254 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6256 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6258 *) Add documentation file and src/Configuration.tmpl entry for the
6259 experimental mod_mmap_static module. Because although it is and marked as
6260 an experimental one it is distributed and thus should be documented and
6261 prepared for configuration the same way as all others modules.
6262 [Ralf S. Engelschall]
6264 *) Add query (-q) option to apxs support tool to be able to manually query
6265 specific settings from apxs. This is needed for instance when you
6266 manually want to access Apache's header files and you need to assemble
6267 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6268 [Ralf S. Engelschall]
6270 *) Now src/Configure uses a fallback strategy for the shared object support
6271 on platforms where no explicit information is available: If a Perl
6272 installation exists we ask it about its shared object support and if it's
6273 the dlopen-style one we shamelessly guess the compiler and linker flags
6274 for creating shared objects from Perls knowledge. Of course, the user is
6275 warning about what we are doing and informed that he should send us
6276 the guessed flags when they work. [Ralf S. Engelschall]
6278 *) Provide APACI --without-support option to be able to disable the build
6279 and installation of the support tools from the src/support/ area.
6280 Although its useful to have these installed per default we should provide
6281 a way to compile and install without them for backward-compatibility.
6282 [Ralf S. Engelschall]
6284 *) Add of the new APache eXtenSion (apxs) support tool for building and
6285 installing modules into an _already installed_ Apache package through the
6286 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6287 this approach actually doesn't need the Apache source tree. The
6288 (APACI-installed) server package is enough, because this now includes the
6289 Apache C header files (PREFIX/include) and the new APXS tool
6290 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6291 module authors to build their Apache modules _OUTSIDE_ the Apache source
6292 tree while avoiding them to fiddle around with the totally platform
6293 dependend way of compiling DSO files. The tool supports all ranges of
6294 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6295 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6296 on-the-fly generate a minimalistic Makefile and sample module for the
6297 first step to provide both a quick success event and to demonstrate the
6298 APXS mechanism to module authors. [Ralf S. Engelschall]
6300 *) Fix core dumps in use of CONNECT in proxy.
6301 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6303 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6304 so that users have examples of how CustomLog can be used.
6307 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6308 the Apache distribution tree. Until Apache 1.3 there was no real
6309 out-of-the-box batch-capable build and installation procedure for the
6310 complete Apache package. This is now provided by a top-level "configure"
6311 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6312 to provide a GNU Autoconf-style frontend which is capable to both drive
6313 the old src/Configure stuff in batch and additionally installs the
6314 package with a GNU-conforming directory layout. Any options from the old
6315 configuration scheme are available plus a lot of new options for flexibly
6316 customizing Apache. [Ralf S. Engelschall]
6318 *) The floating point ap_snprintf code wasn't threadsafe.
6319 Had to remove the HAVE_CVT macro in order to do threadsafe
6320 calling of the ?cvt() floating point routines. [Dean Gaudet]
6322 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6324 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
6325 [Jim Jagielski] PR#1901
6327 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6328 Configure knows which CC we are using. [Jim Jagielski]
6330 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6331 was defined in a parent directory. [Lars Eilebrecht]
6333 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6334 a generic printf-style routine that can call arbitrary output
6335 routines. Use this to replace http_bprintf.c. Add new routines
6336 psprintf(), pvsprintf() which allocate the exact amount of memory
6337 required for a string from a pool. Use psprintf() to clean up
6338 various bits of code which used ap_snprintf()/pstrdup().
6341 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6342 ap_snprintf() has different semantics and formatting codes than
6343 snprintf(). [Dean Gaudet]
6345 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6346 is necessary on at least Solaris where the /etc/rc?.d scripts
6347 are run with these signals ignored, and "SIG_IGN" settings are
6348 maintained across exec().

6374 [Jürgen Keil <jk@tools.de>] PR#2000
6376 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6377 therefore not exposed to %2F -> '/' translations and 2) the request
6378 is a proxy request, so we're not dealing with a local resource anyway.
6379 Without this, the proxy would fail to work for any URL's with
6380 %2f in them (occurs quite often in
6381 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6383 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6385 *) Make the shared object compilation command more portable by avoiding
6386 the direct combination of `-c' & `-o' which is not honored by some
6387 compilers like UnixWare's cc. [Ralf S. Engelschall]
6389 *) WIN32: the proxy was creating filenames missing the last four

6398 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6399 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6400 name was really too generic, added documentation for this directive to
6401 the mod_proxy.html and corrected the hyperlink to it in the

6407 *) Make Configure die when you give it an unknown command switch.
6410 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6411 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6412 and per default compiled support programs have manual pages - just to
6413 document our stuff a little bit more and to be able to do really
6414 Unix-like installations ;-) [Ralf S. Engelschall]
6416 *) Major cleanups to the Configure script to make it and its generated
6417 Makefiles again readable and maintainable: add SRCDIR option, removed
6418 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6419 generated sections, consequently added Makefile headers with inheritance
6420 information, added subdir movement messages for easier following where
6421 the build process currently stays (more verbose then standard Make, less
6422 verbose than GNU make), same style to comments in the Configure script,
6423 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6425 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6426 from the ZeusBench benchmarking program and can be used to determine the

6430 [Ralf S. Engelschall]
6432 *) API: Various core functions that are definately not part of the API
6433 have been made static, and a few have been marked API_EXPORT. Still
6434 more have been marked CORE_EXPORT and are not intended for general
6435 use by modules. [Doug MacEachern, Dean Gaudet]
6437 *) mod_proxy was not clearing the Proxy-Connection header from
6438 requests; now it does. This did not violate any spec, however
6439 causes poor interactions when you are talking to remote proxies.
6440 [Marc Slemko] PR#1741
6442 *) Various cleanups to the command line interface and manual pages.
6443 [Ralf S. Engelschall]
6445 *) cfg_getline() was not properly handling lines that did not end
6446 with a line termination character. [Marc Slemko] PR#1869, 1909
6448 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6450 *) Clean up some undocumented behavior of mod_setenvif related to
6451 "merging" two SetEnvIf directives when they match the same header
6452 and regex. Document that mod_setenvif will perform comparisons in
6453 the order they appear in the config file. Optimize mod_setenvif by
6454 doing more work at config time rather than at runtime.
6457 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6458 to allow for modules to overrule them and to reduce redefinition
6459 warnings [Jim Jagielski]
6461 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6464 *) Making the hard-coded cross-module function call mime_find_ct() (from
6465 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6466 checking is really called even for proxy requests except for URLs with
6467 HTTP schemes (because there we can optimize by not running the type
6468 checking hooks due to the fact that the proxy gets the MIME Content-type
6469 from the remote host later). This change cleans up mod_mime by removing
6470 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6471 especially unbundles mod_proxy and mod_mime. This way they both now can
6472 be compiled as shared objects and are no longer tied together.
6473 [Ralf S. Engelschall]
6475 *) util.c cleanup and speedup. [Dean Gaudet]
6477 *) API: Clarification, pstrndup() will always copy n bytes of the source
6478 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6480 *) Mark module command_rec and handler_rec structures const so that they
6481 end up in the read-only data section (and are friendlier to systems
6482 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6484 *) Add check to the "Port" directive to make sure the specified
6485 port is in the appropriate range. [Ben Hyde]
6487 *) Performance improvements to invoke_handler().
6488 [Dmitry Khrustalev <dima@bog.msu.su>]
6490 *) Added support for building shared objects even for library-style modules
6491 (which are built from more than one object file). This now provides the
6492 ability to build mod_proxy as a shared object module. Additionally
6493 modules like mod_example are now also supported for shared object
6494 building because the generated Makefiles now no longer assume there is at
6495 least one statically linked module. [Ralf S. Engelschall]
6497 *) API: Clarify usage of content_type, handler, content_encoding,
6498 content_language and content_languages fields in request_rec. They
6499 must always be lowercased; and the strings pointed to shouldn't
6500 be modified (you must copy them to modify them). Fix a few bugs
6501 related to this. [Dean Gaudet]
6503 *) API: Clarification: except for RAW_ARGS, all command handlers can
6504 treat the char * parameters as permanent, and modifiable. There
6505 is no need to pstrdup() them. Clean up some needless pstrdup().
6508 *) Now mod_so keeps track of which module shared objects with which names
6509 are loaded and thus avoids multiple loading and unloading and irritating
6510 error_log messages. [Ralf S. Engelschall]
6512 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6513 environment variable in the apache core. But that tweaking interferes
6514 with mod_setenv. So don't tweak if the user has specified an explicit
6515 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6517 *) rputs() did not calculate r->sent_bodyct properly.
6518 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6520 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6521 name, or left unset if this value is unavailable. Apache was setting
6522 it to the IP address when unavailable.
6523 [Tony Finch <fanf@demon.net>] PR#1925
6525 *) Various improvements to the configuration and build support for compiling
6526 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6527 OSF1 support with GCC and vendor compilers was added. This way shared
6528 object support is now provided out-of-the-box for FreeBSD, Linux,
6529 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6530 [Ralf S. Engelschall]
6532 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6533 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6534 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6536 *) Fix one more special locking problem for RewriteMap programs in
6537 mod_rewrite: According to the documentation of flock(), "Locks are on
6538 files, not file descriptors. That is, file descriptors duplicated
6539 through dup(2) or fork(2) do not result in multiple instances of a lock,
6540 but rather multiple references to a single lock. If a process holding a
6541 lock on a file forks and the child explicitly unlocks the file, the
6542 parent will lose its lock.". To overcome this we have to make sure the
6543 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6544 the case by opening it in the child_init instead of the module_init API
6545 hook. [Ralf S. Engelschall] PR#1029
6547 *) Change to Location and LocationMatch semantics. LocationMatch no
6548 longer lets a single slash match multiple adjacent slashes in the
6549 URL. This change is for consistency with RewriteRule and
6550 AliasMatch. Multiple slashes have meaning in URLs that they do
6551 not have in (some) filesystems. Location on the other hand can
6552 be considered a shorthand for a more complicated regex, and it
6553 does match multiple slashes with a single slash -- which is
6554 also consistent with the Alias directive.
6555 [Dean Gaudet] related PR#1440
6557 *) Fix bug with mod_mime_magic causing certain files, including files
6558 of length 0, to result in no response from the server.
6561 *) The Configure script now generates src/include/ap_config.h which
6562 contains the set of defines used when Apache is compiled on a platform.
6563 This file can then be included by external modules before including
6564 any Apache header files in case they are being built separately from
6565 Apache. Along with this change, a couple of minor changes were
6566 made to make Apache's #defines coexist peacefully with any autoconf
6567 defines an external module might have. [Rasmus Lerdorf]
6569 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6570 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6571 chance by the API to initialize its per-server configuration and thus
6572 receives the wrong one from the main server. This is now avoided by
6573 remembering the server together with the config structure while
6574 configuring and later assuming there is no config when we see a
6575 difference between the remembered server and the one calling us.
6576 [Ralf S. Engelschall] PR#1790
6578 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6579 is automatically disabled under configure time when the dbm_xxx functions
6580 are not available. Second, two heavy source code errors in the DBM
6581 support code were fixed. This makes DBM RewriteMap's usable again after
6582 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6584 *) Now all configuration files support Unix-style line-continuation via
6585 the trailing backslash ("\") character. This enables us to write down
6586 complex or just very long directives in a more readable way. The
6587 backslash character has to be really the last character before the
6588 newline and it has not been prefixed by another (escaping) backslash.
6589 [Ralf S. Engelschall]
6591 *) When using ProxyPass the ?querystring was not passed correctly.
6592 [Joel Truher <truher@wired.com>]
6594 *) To deal with modules being compiled and [dynamically] linked
6595 at a different time from the core, the SERVER_VERSION and
6596 SERVER_BUILT symbols have been abstracted through the new
6597 API routines apapi_get_server_version() and apapi_get_server_built().
6600 *) WIN32: Preserve trailing slash in canonical path (and hence
6601 in PATH_INFO). [Paul Sutton, Ben Laurie]
6603 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6604 depending on the rev of Solaris and what mixture of modules
6605 are in use. So it has been disabled, and Solaris is back to
6606 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6607 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6608 up static content only servers. Or it may fail unpredictably.
6609 [Dean Gaudet] PR#1779, 1854, 1904
6611 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6614 *) API: Rewrite of absoluteURI handling, and in particular how
6615 absoluteURIs match vhosts. Unless a request is a proxy request, a
6616 "http://host" url is treated as if a similar "Host:" header had been
6617 supplied. This change was made to support future HTTP/1.x protocols
6618 which may require clients to send absoluteURIs for all requests.
6620 In order to achieve this change subtle changes were made to the API. In a
6621 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6622 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6623 by the core, modules must set it during the post_read_request or
6624 translate_names phase.
6626 Plus changes to the virtualhost test suite for absoluteURI testing.
6628 This fixes several bugs with the proxy proxying requests to vhosts
6629 managed by the same httpd.
6632 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6633 code from mod_rewrite. The vhost matching is now performed by a
6634 globally available function matches_request_vhost(). [Dean Gaudet]
6636 *) Reduce memory usage, and speed up ServerAlias support. As a
6637 side-effect users can list multiple ServerAlias directives
6638 and they're all considered.
6639 [Chia-liang Kao <clkao@cirx.org>] PR#1531
6641 *) The "poly" directive in image maps did not include the borders of the
6642 polygon, whereas the "rect" directive does. Fix this inconsistency.
6643 [Konstantin Morshnev <moko@design.ru>] PR#1771
6645 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
6647 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
6648 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
6650 *) API: A new source module main/util_uri.c; It contains a routine
6651 parse_uri_components() and friends which breaks a URI into its component
6652 parts. These parts are stored in a uri_components structure called
6653 parsed_uri within each request_rec, and are available to all modules.
6654 Additionally, an unparse routine is supplied which re-assembles the URI
6655 components back to an URI, optionally hiding the username:password@ part
6656 from ftp proxy requests, and other useful routines. Within the structure,
6657 you find on a ready-for-use basis:
6658 scheme; /* scheme ("http"/"ftp"/...) */
6659 hostinfo; /* combined [user[:password]@]host[:port] */
6660 user; /* user name, as in http://user:passwd@host:port/ */
6661 password; /* password, as in http://user:passwd@host:port/ */
6662 hostname; /* hostname from URI (or from Host: header) */
6663 port_str; /* port string (integer representation is in "port") */
6664 path; /* the request path (or "/" if only scheme://host was given) */
6665 query; /* Everything after a '?' in the path, if present */
6666 fragment; /* Trailing "#fragment" string, if present */
6667 This is meant to serve as the platform for *BIG* savings in
6668 code complexity for the proxy module (and maybe the vhost logic).
6671 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6672 ${map:key}) available for all location where a string is created in
6673 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6674 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6675 possible expansions are consequently usable at all string creation
6676 locations. [Ralf S. Engelschall]
6678 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6679 and not 1) and the per-virtual-server merging of directives. Now all
6680 directives except `RewriteEngine' and `RewriteOption' are either
6681 completely overridden (default) or completely inherited (when
6682 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
6684 *) Fix `RewriteMap' program lookup in situations where such maps are
6685 defined but disabled (`RewriteEngine off') in per-server context.
6686 [Ralf S. Engelschall] PR#1431
6688 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6689 server to bind to port 0 rather than 80. [Dean Gaudet]
6691 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6692 (like SunOS and FreeBSD) which don't accept the locking of pipes
6693 directly. A new directive RewriteLock is introduced which can be used to
6694 setup a separate locking file which then is used for synchronization.
6695 [Ralf S. Engelschall] PR#1029
6697 *) WIN32: The server root is obtained from the registry key
6698 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
6699 "1.3 beta"), unless overridden by the -d command line flag. The
6700 value is stored by running "apache -i -d serverroot". [Paul Sutton]
6702 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
6703 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]
6705 *) Now mod_rewrite no longer makes problematic assumptions on the characters
6706 a username can contain when trying to expand it via /etc/passwd.
6707 [Ralf S. Engelschall]
6709 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6710 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6712 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6713 type but with a special post-processing for the looked-up value: It
6714 parses it into alternatives according to `|' chars and then only one
6715 particular alternative is chosen randomly (this is an essential
6716 functionality needed for balancing between backend-servers when using
6717 Apache as a Reverse Proxy. The looked up value here is a list of
6718 servers). Second, `int' with the built-in maps named `tolower' and
6719 `toupper' which can be used to map URL parts to a fixed case (this is an
6720 essential feature to fix the case of server names when doing mass
6721 virtual-hosting with the help of mod_rewrite instead of using
6722 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6723 Jay Soffian <jay@cimedia.com>] PR#1631
6725 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6726 This directive lets Apache adjust the URL in Location-headers on HTTP
6727 redirect responses sent by the remote server. This way the virtually
6728 mapped area is no longer left on redirects and thus by-passed which is
6729 especially essential when running Apache as a reverse proxy.
6730 [Ralf S. Engelschall]
6732 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
6733 hidden. [Alvaro Martinez Echevarria]
6735 *) Apache will, when started with the -X (single process) debugging flag,
6736 honor the SIGINT or SIGQUIT signals again now. This capability got lost
6737 a while ago during OS/2 signal handling changes.
6739 *) [PORT] Work around the fact that NeXT runs on more than the
6740 m68k chips in mod_status [Scott Anguish and Timothy Luoma
6743 *) [PORT] Recognize FreeBSD versions so we can use the OS regex as well
6744 as handling unsigned-chars for FreeBSD v3 and v2 [Andrey Chernov
6745 <ache@nagual.pp.ru> and Jim] PR#1450
6747 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
6748 In particular the handlers could trigger themselves into an infinite
6749 loop if RLimitMem was used with a small amount of memory -- too small
6750 for the signal stack frame to be set up. [Dean Gaudet]

6764 *) mod_info would occasionally produce an unpaired <tt> in its
6765 output. Fixed. [Martin Kraemer]
6767 *) By default AIX binds a process (and it's children) to a single
6768 processor. httpd children now unbind themselves from that cpu
6769 and re-bind to one selected at random via bindprocessor()
6772 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
6773 effect. Work around it by using RLIMIT_AS for the RLimitMEM
6774 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
6776 *) mod_mime_magic error message should indicate the filename when
6777 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
6779 *) Previously Apache would permit </Files> to end <FilesMatch> (and
6780 similary for Location and Directory), now this is diagnosed as an
6781 error. Improve error messages for mismatched sections (<Files>,
6782 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).

6788 *) <Files> with wildcards was broken by the change in wildcard
6789 semantics (* does not match /). To fix this, <Files> now

6834 has been bumped accordingly. [Paul Sutton]
6836 *) All BrowserMatch directives mentioned in
6837 htdocs/manual/known_client_problems.html are in the default
6838 configuration files. [Lars Eilebrecht]
6840 *) MiNT port update. [Jan Paul Schmidt]
6842 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
6843 equivalent, similarly for x-compress and compress. Apache
6844 now ignores a leading x- when comparing encodings. It also
6845 preserves the encoding the client requests (for example if
6846 it requests x-gzip, then Apache will respond with x-gzip
6847 in the Content-Encoding header).

6850 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
6852 *) Added mod_so module to support dynamic loading of modules on Unix

6854 instead of AddModule in Configuration to build shared modules
6855 [Sameer Parekh, Paul Sutton]
6857 *) Minor cleanups to r->finfo handling in some modules.
6860 *) Abstract read()/write() to ap_read()/ap_write().
6861 Makes it easier to add other types of IO code such as SFIO.
6864 *) API: Generalize default_port manipulations to make support of
6865 different protocols easier. [Ben Laurie, Randy Terbush]
6867 *) There are many cases where users do not want Apache to form
6868 self-referential urls using the "canonical" ServerName and Port.
6869 The new UseCanonicalName directive (default on), if set to off
6870 will cause Apache to use the client-supplied hostname and port.

6875 PR#315, 459, 485, 1433
6877 *) Yet another rearrangement of the source tree.. now all the common
6878 header files are in the src/include directory. The -Imain -Iap
6879 references in Makefiles have been changed to the simpler -Iinclude
6880 instead. In addition to simplifying the build a little bit, this
6881 also makes it clear when a module is referencing something in a
6882 other than kosher manner (e.g., the proxy including mod_mime.h).
6883 Module-private header files (the proxy, mod_mime, the regex library,
6884 and mod_rewrite) have not been moved to src/include; nor have
6885 the OS-abstraction files. [Ken Coar]
6887 *) Fix a bug where r->hostname didn't have the :port stripped
6888 from it. [Dean Gaudet]
6890 *) Tweaked the headers_out table size, and the subprocess_env
6891 table size guess in rename_original_environment(). Added
6892 MAKE_TABLE_PROFILE which can help discover make_table()
6893 calls that use too small an initial guess, see alloc.c.
6896 *) Options and AllowOverride weren't properly merging in the main
6897 server setting inside vhosts (only an issue when you have no
6898 <Directory> or other section containing an Options that affects
6899 a request). Options +foo or -foo in the main_server wouldn't
6900 affect the main_server's lookup defaults. [Dean Gaudet]
6902 *) Variable 'cwd' was being used pointlessly before being set.
6905 *) r->allowed handling cleaned up in the standard modules.
6908 *) Some case-sensitivity issues cleaned up to be consistent with

6911 *) SIGURG doesn't exist everywhere.
6912 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6914 *) mod_unique_id was erroneously generating a second unique id when
6915 an internal redirect occured. Such redirects occur, for example,
6916 when processing a DirectoryIndex match. [Dean Gaudet]
6918 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6919 of the key and value. But in many cases this is not required
6920 because the key/value is a constant, or the value has been built
6921 by pstrcat() or other similar means. New routines table_addn,
6922 table_mergen, and table_setn have been added to the API, these
6923 routines do not pstrdup() their arguments. The core code and
6924 standard modules were changed to take advantage of these routines.
6925 The resulting server is up to 20% faster in some situations.
6927 Note that it is easy to get code subtly wrong if you pass a key/value
6928 which is in a pool other than the pool of the table. The only
6929 safe thing to do is to pass key/values which are in the pool of
6930 the table, or in one of the ancestors of the pool of the table.
6931 i.e. if the table is part of a subrequest, a value from the main
6932 request's pool is OK since the subrequest pool is a sub_pool of the
6933 main request's pool (and therefore has a lifespan at most as long as
6934 the main pool). There is debugging code which can detect improper
6935 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6936 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6938 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6939 which don't exist on disk more gracefully; handles vhosts properly.
6940 Update documentation to reflect the code -- if there's no
6941 MimeMagicFile directive then the module is not enabled.
6944 *) PORT: Some older *nix dialects cannot automatically start scripts
6945 which begin with a #! interpreter line (the shell starts the scripts
6946 appropriately on these platforms). Apache now supports starting of
6947 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6948 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6951 *) API: "typedef array_header table" removed from alloc.h, folks should
6952 have been writing to use table as if it were an opaque type, but even
6953 some standard modules got this wrong. By changing the definition
6954 to "typedef struct table table" module authors will receive compile
6955 time warnings that they're doing the wrong thing. This change
6956 facilitates future changes with more sophisticated table
6957 structures. Specifically, module authors should be using table_elts()
6958 to get access to an array_header * for the table. [Dean Gaudet]
6960 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6961 library routines. [Ken Coar, Rasmus Lerdorf]
6963 *) WIN32: mod_speling is now available on the Win32 platform.
6966 *) For clarity the following compile time definition was changed:
6968 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6970 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6971 and not be a general notice that the OS has mmap(). Now the
6972 HAVE_MMAP/SHMGET #defines strictly are informational that the
6973 OS has that method of shared memory; the type to use for
6974 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6975 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6976 determine if shared memory is available and allows Apache
6977 to determine the best method to use for the scoreboard.
6980 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6981 as do various earlier versions. It should be safe on all versions.

7006 The choice of flock vs. fcntl was made based on timings which showed that
7007 even on non-NFS, non-exported filesystems fcntl() was an order of

7456 *) PORT: Basic Gemini port (treat it like unixware212).
7457 ["Pavel Yakovlev (Paul McHacker)" <hac@tomcat.olly.ru>]
7459 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
7460 use USE_SHMGET_SCOREBOARD.
7463 *) Various improvements in detecting config file errors (missing closing
7464 directives for <Directory>, <Files> etc. blocks, prohibiting global
7465 server settings in <VirtualHost> blocks, flagging unhandled multiple
7466 arguments to <Directory>, <Files> etc.)
7469 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
7470 variable to provide this one to suexec'd CGIs, too.
7471 [M.D.Parker <mdpc@netcom.com>] PR#1284
7473 *) New support tool: src/support/split-logfile, a sample Perl script which
7474 splits up a combined access log into separate files based on the
7475 name of the virtual host (listed first in the log records by "%v").
7478 Changes with Apache 1.3b2 (there is no 1.3b1)
7480 *) TestCompile was not passing $LIBS [Dean Gaudet]
7482 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7485 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7486 rudimentary memory debugger which can be used on live servers with
7487 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7488 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7489 and free() for each object. This is far more expensive and should
7490 only be used for testing with tools such as Electric Fence and
7491 Purify. See main/alloc.c for more details. [Dean Gaudet]
7493 *) Configure uses a sh trap and didn't set its exitcode properly.
7494 [Dean Gaudet] PR#1159
7496 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7497 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7498 From a given ip:port, regardless what the Host: header is, you can
7499 only reach the vhosts defined on that ip:port. The precedence of
7500 vhosts was reversed to match other precedences in the config --
7501 the earlier vhosts override the later vhosts. All vhost matching was
7502 moved into http_vhost.[ch]. [Dean Gaudet]
7504 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7505 be used for whatever reason is appropriate (i.e. format() warnings
7506 for printf style functions). Both are enabled only with
7507 gcc >= 2.7.x (so that we have fewer support issues with older
7508 versions). [Dean Gaudet]
7510 *) Fix support for Proxy Authentication (we were testing the response
7511 status too early). [Marc Slemko]
7513 *) CoreDumpDirectory directive directs where the core file is
7514 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7515 received. [Marc Slemko, Dean Gaudet]
7517 *) PORT: Support for Atari MINT.
7518 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7520 *) When booting, apache will now detach itself from stdin, stdout,
7521 and stderr. stderr will not be detached until after the config
7522 files have been read so you will be able to see initial error
7523 messages. After that all errors are logged in the error_log.
7524 This makes it more convenient to start apache via rsh, ssh,
7525 or crontabs. [Dean Gaudet] PR#523
7527 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7528 Also removed the auto-generated link to www.apache.org that was the
7529 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7531 *) send_fb would not detect aborted connections in some situations.
7534 *) mod_include would use uninitialized data when parsing certain
7535 expressions involving && and ||. [Brian Slesinsky] PR#1139
7537 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7539 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7541 *) mod_autoindex improperly counted &escapes; as more than one
7542 character in the description. It also improperly truncated
7543 descriptions that were exactly the maximum length.
7546 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7547 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7550 *) mod_include now uses symbolic names to check for request success
7551 and return HTTP errors, and correctly handles all types of
7552 redirections (previously it only did temporary redirect correctly).
7553 [Ken Coar, Roy Fielding]
7555 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7556 r->filename. Since those two are meant to be in sync with each other
7557 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7559 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7560 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7562 *) Inetd mode (which is buggy) uses timeouts without having setup the
7563 jmpbuffer. [Dean Gaudet] PR#1064
7565 *) Work around problem under Linux where a child will start looping
7566 reporting a select error over and over.
7567 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7569 *) Fixed error in proxy_util.c when looping through multiple host IP
7570 addresses. [Lars Eilebrecht] PR#974
7572 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7573 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7574 bytes before writing, but it will never split a log entry across a
7575 buffer boundary. [Dean Gaudet]
7577 *) API: the short_score record has been split into two pieces, one which
7578 the parent writes on, and one which the child writes on. As part of
7579 this change the get_scoreboard_info() function was removed, and
7580 scoreboard_image was exported. This change fixes a race condition
7581 in file based scoreboard systems, and speeds up changes involving the
7582 scoreboard in earlier 1.3 development. [Dean Gaudet]
7584 *) API: New register_other_child() API (see http_main.h) which allows
7585 modules to register children with the parent for maintenance. It
7586 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7588 *) API: New piped_log API (see http_log.h) which implements piped logs,
7589 and will use register_other_child to implement reliable piped logs
7590 when it is available. The reliable piped logs part can be disabled
7591 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7592 logs is only available on Unix. [Dean Gaudet]
7594 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7595 meets_conditions(). This allows conditional HTTP selection to be
7596 handled separately from the storing of the header fields, and provides
7597 the ability for CGIs to set their own ETags for conditional checking.
7598 [Ken Coar, Roy Fielding] PR#895
7600 *) Changes to mod_log_config to allow naming of format strings.
7601 Format nicknames are defined with "LogFormat fmt nickname", and can
7602 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7605 *) New module, "mod_speling", which can help find files even when
7606 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7608 *) API: New function child_terminate() triggers the child process to
7609 exit, while allowing the child finish what it needs to for the
7610 current request first.
7611 [Doug MacEachern, Alexei Kosut]
7613 *) Windows now defaults to using full status reports with mod_status.
7614 [Alexei Kosut] PR #1094
7616 *) *Really* disable all mod_rewrite operations if the engine is off.
7617 Some things (like RewriteMaps) were checked/performed even if they
7618 weren't supposed to be. [Ken Coar] PR #991
7620 *) Implement a new timer scheme which eliminates the need to call alarm() all
7621 the time. Instead a counter in the scoreboard for each child is used to
7622 show when the child has made forward progress. The parent samples this
7623 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7624 progress has been made in the timeout period. This reduces the static
7625 request best-case syscall count to 22 from 29. This scheme is only
7626 used by systems with memory-based scoreboards. [Dean Gaudet]
7628 *) The proxy now properly handles CONNECT requests which are sent
7629 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7631 *) A script called apachectl has been added to the support
7632 directory. This script allows you to do things such as
7633 "apachectl start" and "apachectl restart" from the command
7636 *) Modules and core routines are now put into libraries, which
7637 simplifies the link line tremendously (among other advantages).
7640 *) Some of the MD5 names defined in Apache have been renamed to have
7641 an `ap_' prefix to avoid conflicts with routines supplied by
7642 external libraries. [Ken Coar]
7644 *) Removal of mod_auth_msql.c from the distribution. There are many
7645 other options for databases today. Rather than offer one option,
7646 offer none at this time. mod_auth_msql and other SQL database
7647 authentication modules can be found at the Apache Module Registry.
7648 http://modules.apache.org/ It would be nice to offer a generic
7649 mod_auth_sql option in the near future.
7651 *) PORT: BeOS support added [Alexei Kosut]
7653 *) Configure no longer accepts the -make option, since it creates
7654 Makefile on the fly based on Makefile.tmpl and Configuration.
7656 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7657 of forcibly killing off all its processes and exiting without
7658 cleaning up. [Alexei Kosut]
7660 *) API: A new field in the request_rec, r->mtime, has been added to
7661 avoid gratuitous parsing of date strings. It is intended to hold
7662 the last-modified date of the resource (if applicable). An
7663 update_mtime() routine has also been added to advance it if
7664 appropriate. [Roy Fielding, Ken Coar]
7666 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7667 deny access to the directory with a HTTP_FORBIDDEN. The previous
7668 behavior was to ignore the htaccess file if it could not be read.
7669 This change may make some setups with unreadable htaccess files
7670 stop working. [Marc Slemko] PR#817
7672 *) Add aplog_error() providing a mechanism to define levels of
7673 verbosity to the server error logging. This addition also provides
7674 the ability to log errors using syslogd. Error logging is configurable
7675 on a per-server basis using the LogLevel directive. Conversion
7676 of log_*() in progress. [Randy Terbush]
7678 *) Further enhance aplog_error() to not log filename, line number, and
7679 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7681 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7682 converted to long ones. Backslashes are converted to forward
7683 slashes. Case is converted to lower. Parts of URLs that do not
7684 correspond to files are left completely alone. [Ben Laurie]
7686 *) PORT: 2 new OSs added to the list of ports:
7687 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7688 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7690 *) Add the server version (SERVER_VERSION macro) to the "server
7691 configured and running" entry in the error_log. Also build an
7692 object file at link-time that contains the current time
7693 (SERVER_BUILT global const char[]), and include that in the
7696 *) Set r->headers_out when sending responses from the proxy.
7697 This fixes things such as the logging of headers sent from
7698 the proxy. [Marc Slemko] PR#659
7700 *) support/httpd_monitor is no longer distributed because the
7701 scoreboard should not be file based if at all possible. Use
7702 mod_status to see current server snapshot.
7704 *) (set_file_slot): New function, allowing auth directives to be
7705 independent of the server root, so the server documents can be
7706 moved to a different directory or machine more easily.
7707 [David J. MacKenzie]
7709 *) If no TransferLog is given explicitly, decline
7710 to log. This supports coexistence with other logging modules,
7711 such as the custom one that UUNET uses. [David J. MacKenzie]
7713 *) Check for titles in server-parsed HTML files.
7714 Ignore leading newlines and returns in titles. The old behavior
7715 of replacing a newline after <title> with a space causes the
7716 title to be misaligned in the listing. [David J. MacKenzie]
7718 *) Change mod_cern_meta to be configurable on a per-directory basis.
7719 [David J. MacKenzie]
7721 *) Add 'Include' directive to allow inclusion of configuration
7722 files within configuration files. [Randy Terbush]
7724 *) Proxy errors on connect() are logged to the error_log (nothing
7725 new); now they include the IP address and port that failed
7726 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7728 *) Various architectures now define USE_MMAP_FILES which causes
7729 the server to use mmap() for static files. There are two
7730 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7731 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7732 number of bytes written in one cycle from a single mmap()d object,
7733 default 32768). [Dean Gaudet]
7735 *) API: Added post_read_request API phase which is run right after reading
7736 the request from a client, or right after an internal redirect. It is
7737 useful for modules setting environment variables that depend only on
7738 the headers/contents of the request. It does not run during subrequests
7739 because subrequests inherit pretty much everything from the main
7740 request. [Dean Gaudet]
7742 *) Added mod_unique_id which is used to generate a unique identifier for
7743 each hit, available in the environment variable UNIQUE_ID.
7746 *) init_modules is now called after the error logs have been opened. This
7747 allows modules to emit information messages into the error logs.
7750 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7751 information for case where proxy module is not available. [Marc Slemko]
7753 *) PORT: Apache has need for mutexes to serialize its children around
7754 accept. In prior versions either fcntl file locking or flock file
7755 locking were used. The method is chosen by the definition of
7756 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7757 and FLOCK for flock(). New options have been added:
7758 - SYSVSEM to use System V style semaphores
7759 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7760 - USLOCK to use IRIX uslock
7761 Based on timing various techniques, the following changes were made
7763 - Linux 2.x uses flock instead of fcntl
7764 - Solaris 2.x uses pthreads
7765 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7766 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7767 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7768 Martijn Koster <m.koster@pobox.com>]
7770 *) PORT: The semantics of accept/select make it very desirable to use
7771 mutexes to serialize accept when multiple Listens are in use. But
7772 in the case where only a single socket is open it is sometimes
7773 redundant to serialize accept(). Not all unixes do a good job with
7774 potentially dozens of children blocked on accept() on the same
7775 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7776 the server will avoid serialization when listening on only one socket,
7777 and use serialization when listening on multiple sockets.
7778 [Dean Gaudet] PR#467
7780 *) Configure changes: TestLib replaced by TestCompile, which has
7781 some additional capability (such as doing a sanity check of
7782 the compiler and flags selected); the version of Solaris is now
7783 available via the #define value of SOLARIS2; IRIX n32bit libs
7784 now supported and selectable by new Configuration Rule: IRIXN32;
7785 We no longer default to -O2 optimization. [Jim Jagielski]
7787 *) Updated Configure: Configuration now uses AddModule to specify
7788 module source or binary file location, relative to src directory.
7789 Modules can be dropped into modules/extra, or in their own
7790 directory, and modules can come with a Makefile or Configure can
7791 create one. Modules can add compiler or library information to
7792 generated Makefiles. [Paul Sutton]
7794 *) Source core re-organisation: distributed modules are now in
7795 modules/standard. All other source code is in main. OS-specific
7796 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7798 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7801 *) Fix another long-standing bug in sub_req_lookup_file where it would
7802 happily skip past access checks on subdirectories looked up with
7803 relative paths. (It's used by mod_dir, mod_negotiation,
7804 and mod_include.) [Dean Gaudet]
7806 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7807 N is the number of <Directory> sections, and M is the number of
7808 components in the filename of an object.
7810 To achieve this optimization the following config changes were made:
7811 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7812 <Files>s, and <Location>s now treat a slash as a special
7813 character. For example "/home/*/public_html" previously would
7814 match "/home/a/andrew/public_html", now it only matches things
7815 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7816 - It's possible now to use [] wildcarding in <Directory>, <Files>
7818 - Regex <Directory>s are applied after all non-regex <Directory>s.
7822 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7823 and corrupted paths. [Dean Gaudet]
7825 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7826 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7827 be accessed now via backreferences $1..$9 in RewriteConds test-against
7828 strings in addition to RewriteRules subst string. Second the grouped
7829 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7830 via backreferences %1..%9 both in following RewriteCond test-against
7831 strings and RewriteRules subst string. This provides maximum flexibility
7832 through the use of backreferences.
7833 Additionally the rewriting engine was cleaned up by putting common
7834 code to the new expand_backrefs_inbuffer() function.
7835 [Ralf S. Engelschall]
7837 *) When merging the main server's <Directory> and <Location> sections into
7838 a vhost, put the main server's first and the vhost's second. Otherwise
7839 the vhost can't override the main server. [Dean Gaudet] PR#717
7841 *) The <Directory> code would merge and re-merge the same section after
7842 a match was found, possibly causing problems with some modules.
7845 *) ip-based vhosts are stored and queried using a hashing function, which
7846 has been shown to improve performance on servers with many ip-vhosts.
7847 Some other changes had to be made to accommodate this:
7848 - the * address for vhosts now behaves like _default_
7849 - the matching process now is:
7850 - match an ip-vhost directly via hash (possibly matches main
7852 - if that fails, just pretend it matched the main server
7853 - if so far only the main server has been matched, perform
7854 name-based lookups (ServerName, ServerAlias, ServerPath)
7855 *only on name-based vhosts*
7856 - if they fail, look for _default_ vhosts
7857 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7859 *) dbmmanage overhaul:
7860 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7861 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7862 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7863 - provide better seed for rand
7864 - prompt for password as per getpass(3) (turn off echo, read from
7866 - use "newstyle" crypt based on $Config{osname} ($^O)
7867 - will not add a user if already in database, use new `update' command
7869 - added `check' command to check a users' password
7870 - added `import' command to convert existing password text-files or
7871 dbm files exported with `view'
7872 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7875 *) Added psocket() which is a pool form of socket(), various places within
7876 the proxy weren't properly blocking alarms while registering the cleanup
7877 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7878 was a bug where the client socket was being close()d twice due a still
7879 registered cleanup. [Dean Gaudet]
7881 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7884 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7885 [Jason Venner <jason@idiom.com>] PR#667
7887 *) Enable ``=""'' for RewriteCond directives to match against
7888 the empty string. This is the preferred way instead of ``^$''.
7889 [Ralf S. Engelschall]
7891 *) Fixed an infinite loop in mod_imap for references above the server root
7892 [Dean Gaudet] PR#748
7894 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7895 SendBufferSize, so that the TCP window can be set appropriately
7896 for LFNs. [Phillip A. Prindeville]
7898 *) mod_browser has been replaced by the more general mod_setenvif
7899 (courtesy of Paul Sutton). BrowserMatch* directives are still
7900 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7901 UnSetEnvIfZero directives. [Ken Coar]
7903 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7904 order for remote_host to be set (for logging, or for the env var
7905 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7908 *) mod_access overhaul:
7909 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7910 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7911 - Critical path was sped up by pre-computing a few things at config time.
7912 - The undocumented syntax "allow user-agents" was removed,
7913 the replacement is "allow from env=foobar" combined with mod_browser.
7914 - When used with hostnames it now forces a double-reverse lookup
7915 no matter what the directory settings are. This double-reverse
7916 doesn't affect any of the other routines that use the remote
7917 hostname. In particular it's still passed to CGIs and the log
7918 without the double-reverse check. Related PR#860.
7921 *) When a large bwrite() occurs (larger than the internal buffer size),
7922 while there is already something in the buffer, apache will combine
7923 the large write and the buffer into a single writev(). (This is
7924 in anticipation of using mmap() for reading files.)
7927 *) In obscure cases where a partial socket write occurred while chunking,
7928 Apache would omit the chunk header/footer on the next block. Cleaned
7929 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7930 a bug where a long pause in DNS lookups could cause the last packet
7931 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7933 *) API: Added child_exit function to module structure. This is called
7934 once per "heavy-weight process" just before a server child exit()'s
7935 e.g. when max_requests_per_child is reached, etc.
7936 [Doug MacEachern, Dean Gaudet]
7938 *) mod_include cleanup showed that handle_else was being used to handle
7939 endif. It didn't cause problems, but it was cleaned up too.
7942 *) mod_cern_meta would attempt to find meta files for the directory itself
7943 in some cases, but not in others. It now avoids it in all cases.
7946 *) mod_mime_magic would core dump if there was a decompression error.
7947 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7949 *) PORT: some variants of DGUX require -lsocket -lnsl
7950 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7952 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7953 by the various fields (name, size, et cetera), either in ascending
7954 or descending order. Just click on the column header. [Ken Coar]
7956 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7957 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7958 the relatively safe direction. [Dean Gaudet] PR#344
7960 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7961 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7963 *) child_main avoids an unneeded call to select() when there is only one
7964 listening socket. [Dean Gaudet]
7966 *) In the event that the server is starved for idle servers it will
7967 spawn 1, then 2, then 4, ..., then 32 servers each second,
7968 doubling each second. It'll also give a warning in the errorlog
7969 since the most common reason for this is a poor StartServers
7970 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7971 the maximum. [Dean Gaudet]
7973 *) Apache now provides an effectively unbuffered connection for
7974 CGI scripts. This means that data will be sent to the client
7975 as soon as the CGI pauses or stops output; previously, Apache would
7976 buffer the output up to a fixed buffer size before sending, which
7977 could result in the user viewing an empty page until the CGI finished
7978 or output a complete buffer. It is no longer necessary to use an
7979 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7980 in a language that by default does buffering (e.g. perl) this
7981 shouldn't have a detrimental effect on performance.
7983 "nph-" CGIs, which formerly provided a direct socket to the client
7984 without any server post-processing, were not fully compatible with
7985 HTTP/1.1 or SSL support. As such they would have had to implement
7986 the transport details, such as encryption or chunking, in order
7987 to work properly in certain situations. Now, the only difference
7988 between nph and non-nph scripts is "non-parsed headers".

7991 *) If a BUFF is switched from buffered to unbuffered reading the first
7992 bread() will return whatever remained in the buffer prior to the
7993 switch. [Dean Gaudet]
7995 Changes with Apache 1.3a1
7997 *) Added another Configure helper script: TestLib. It determines
7998 if a specified library exists. [Jim Jagielski]
8000 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
8001 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
8004 *) PORT: Some architectures use size_t for various lengths in network
8005 functions such as accept(), and getsockname(). The definition
8006 NET_SIZE_T is used to control this. [Dean Gaudet]
8008 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
8009 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
8010 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
8012 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
8013 [Igor N Kovalenko <infoh@mail.wplus.net>]
8015 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8016 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8017 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8018 [Dean Gaudet] related PR#875
8020 *) API: Correct child_init() slot declaration from int to void, to
8021 match the init() declaration. Update mod_example to use the new
8024 *) added transport handle slot (t_handle) to the BUFF structure
8027 *) get_client_block() returns wrong length if policy is

8038 *) AddModuleInfo directive for mod_info which allows you to annotate
8039 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8041 *) Added NoProxy directive to avoid using ProxyRemote for selected
8042 addresses. Added ProxyDomain directive to cause unqualified
8043 names to be qualified by redirection.
8044 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
8046 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8047 header to the remote host in the proxy. [Sameer Parekh and
8050 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8051 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8052 URLs, fixed rewritelog(), fixed forced response code handling on
8053 redirects from within .htaccess files, disabled pipe locking under
8054 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8055 no substitution, bugfixed situations where HostnameLookups is off, made
8056 mod_rewrite more thread-safe for NT port and fixed problem when creating
8057 an empty query string via "xxx?".
8058 This update also removes the copyright of Ralf S. Engelschall,
8059 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8060 exclusively copyrighted by the Apache Group now. This happened because
8061 the author now has gifted mod_rewrite exclusively to the Apache Group and
8062 no longer maintains an external version.
8063 [Ralf S. Engelschall]
8065 *) API: Added child_init function to module structure. This is called
8066 once per "heavy-weight process" before any requests are handled.
8067 See http_config.h for more details. [Dean Gaudet]
8069 *) Anonymous_LogEmail was logging on each subrequest.

8072 *) API: Added is_initial_req() which tests if the request being
8073 processed is the initial request, or a subrequest.

8077 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8079 *) Configure fixed to correctly propagate user-selected options and
8080 settings (such as CC and OPTIM) to Makefiles other than
8081 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8083 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8084 directory indices to start with the contents of the HeaderName file
8085 if there is one. If there isn't one, the behaviour is unchanged.
8086 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8088 *) WIN32: Modules can now be dynamically loaded DLLs using the
8089 LoadModule/LoadFile directives. Note that module DLLs must be
8090 compiled with the multithreaded DLL version of the runtime library.
8091 [Alexei Kosut and Ben Laurie]
8093 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8094 This allows the admin to completely remove automatic indexing
8095 from the server, while still supporting the basic functions of
8096 trailing-slash redirects and DirectoryIndex files. Note that if
8097 you're carrying over an old Configuration file and you use directory
8098 indexing then you'll want to add:
8100 Module autoindex_module mod_autoindex.o
8102 before mod_dir in your Configuration. [Dean Gaudet]
8104 *) popendir/pclosedir created to properly protect directory scanning.
8105 [Dean Gaudet] PR#525
8107 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8108 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8109 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8112 *) The AccessFileName directive can now take more than one filename.
8113 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8115 *) The new mod_mime_magic can be used to "magically" determine the type
8116 of a file if the extension is unknown. Based on the unix file(1)
8117 command. [Ian Kluft <ikluft@cisco.com>]
8119 *) We now determine and display the time spent processing a
8120 request if desired. [Jim Jagielski]
8122 *) mod_status: PID field of "dead" child slots no longer displays
8123 main httpd process's PID. [Jim Jagielski]
8125 *) Makefile.nt added - to build all the bits from the command line:
8126 nmake -f Makefile.nt
8127 Doesn't yet work properly. [Ben Laurie]
8129 *) Default text of 404 error is now "Not Found" rather than the
8130 potentially misleading "File Not Found". [Ken Coar]
8132 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8133 for the net if we require people that actually need this data to
8134 enable it. [Linus Torvalds]
8136 *) directory_walk() is an expensive function, keep a little more state to
8137 avoid needless string counting. Add two new functions make_dirstr_parent
8138 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8139 The new functions are a little less general than make_dirstr, but
8140 work more efficiently (less memory, less string counting).
8143 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8144 to LDFLAGS) to avoid complications with lex rules in make files.
8145 [Dean Gaudet] PR#372
8147 *) run_method optimized to avoid needless scanning over NULLs in the
8148 module list. [Dean Gaudet]
8150 *) Revamp of (unix) scoreboard management code such that it avoids
8151 unnecessary traversals of the scoreboard on each hit. This is
8152 particularly important for high volume sites with a large
8153 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8154 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8155 httpd.h. [Dean Gaudet]
8157 *) In configurations using multiple Listen statements it was possible for
8158 busy sockets to starve other sockets of service. [Dean Gaudet]
8160 *) Added hook so standalone_main can be replaced at compile time
8161 (define STANDALONE_MAIN)
8164 *) Lowest-level read/write functions in buff.c will be replaced with
8165 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8166 compile time. The default sfio discipline will behave as apache
8167 would without sfio compiled in.
8170 *) Enhance UserDir directive (mod_userdir) to accept a list of
8171 usernames for the 'disable' keyword, and add 'enable user...' to
8172 selectively *en*able userdirs if they're globally disabled.
8175 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8176 will work with Netscape dbm files. (dbmmanage will probably not
8177 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8179 *) Add a ListenBacklog directive to control the backlog parameter
8180 passed to listen(). Also change the default to 511 from 512.
8183 *) API: A new handler response DONE which informs apache that the
8184 request has been handled and it can finish off quickly, similar to
8185 how it handles errors. [Rob Hartill]
8187 *) Turn off chunked encoding after sending terminating chunk/footer
8188 so that we can't do it twice by accident. [Roy Fielding]
8190 *) mod_expire also issues Cache-Control: max-age headers.
8193 *) API: Added kill_only_once option for free_proc_chain so that it won't
8194 aggressively try to kill off specific children. For fastcgi.
8195 [Stanley Gambarin <gambarin@OpenMarket.com>]
8197 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8199 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8200 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8201 attributes in the FancyIndexing IMG tags. [Ken Coar]
8203 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8205 *) PORT: Added Windows NT support
8206 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
8208 Changes with Apache 1.2.6
8210 *) mod_include when using XBitHack Full would send ETags in addition to
8211 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8212 [Dean Gaudet] PR#1133
8214 *) SECURITY: When a client connects to a particular port/addr, and
8215 gives a Host: header ensure that the virtual host requested can
8216 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8218 *) Support virtual hosts with wildcard port and/or multiple ports
8219 properly. [Ed Korthof <ed@organic.com>]
8221 *) Fixed some case-sensitivity issues according to RFC2068.
8224 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8225 and mod_include.c. [Dean Gaudet]
8227 *) Variable 'cwd' was being used pointlessly before being set.
8230 *) SIGURG doesn't exist on all platforms.
8231 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8233 *) When an error occurs during a POST, or other operation with a
8234 request body, the body has to be read from the net before allowing
8235 a keepalive session to continue. [Roy Fielding] PR#1399
8237 *) When an error occurs in fcntl() locking suggest the user look up
8238 the docs for LockFile. [Dean Gaudet]
8240 *) table_set() and table_unset() did not deal correctly with
8241 multiple occurrences of the same key. [Stephen Scheck
8242 <sscheck@infonex.net>, Ben Laurie] PR#1604
8244 *) send_fd_length() did not calculate total_bytes_sent properly in error
8245 cases. [Ben Reser <breser@regnow.com>] PR#1366
8247 *) r->connection->user was allocated in the wrong pool causing corruption
8248 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8250 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8251 Also removed the auto-generated link to www.apache.org that was the
8252 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8254 *) Multiple "close" tokens may have been set in the "Connection"
8255 header, not an error, but a waste.
8256 [Ronald.Tschalaer@psi.ch] PR#1683
8258 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8259 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8261 *) It appears the "257th byte" bug (see
8262 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8263 at the 256th byte as well. Fixed. [Dean Gaudet]
8265 *) mod_rewrite would not handle %3f properly in some situations.
8268 *) Apache could generate improperly chunked HTTP/1.1 responses when
8269 the bputc() or rputc() functions were used by modules (such as
8270 mod_include). [Dean Gaudet]
8272 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8273 some ports. [Ralf Engelschall]
8275 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8277 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8279 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8281 Changes with Apache 1.2.5
8283 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8284 only an issue on systems without a MAXDNAME define or where
8285 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8287 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8290 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8291 directory listings. [Marc Slemko]
8293 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8296 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8297 is used to read various types of files such as htaccess and
8298 htpasswd files. [Marc Slemko]
8300 *) SECURITY: Ensure that the buffer returned by ht_time is always
8301 properly null terminated. [Marc Slemko]
8303 *) SECURITY: General mod_include cleanup, including fixing several
8304 possible buffer overflows and a possible infinite loop. This cleanup
8305 was done against 1.3 code and then backported to 1.2, the result
8306 is a large difference (due to indentation cleanup in 1.3 code).
8307 Users interested in seeing a smaller set of relevant differences
8308 should consider comparing against src/modules/standard/mod_include.c
8309 from the 1.3b3 release. Non-indentation changes to mod_include
8310 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8312 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8313 including fixing a possible buffer overflow. This cleanup also
8314 was done with 1.3 code as a basis, see the the previous note
8315 about mod_include. [Dean Gaudet]
8317 *) SECURITY: If a htaccess file can not be read due to bad
8318 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8319 The previous behavior was to ignore the htaccess file if it could not
8320 be read. This change may make some setups with unreadable
8321 htaccess files stop working. PR#817 [Marc Slemko]
8323 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8324 Make it O(n). This inefficiency could be used to mount a denial
8325 of service attack against the Apache server. Thanks to

8351 Changes with Apache 1.2.4
8353 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8354 always making requests with the full-URI instead of just the URI path.
8355 [Marc Slemko, Roy Fielding]
8357 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8358 on this platform. [Marc Slemko]
8360 Changes with Apache 1.2.3
8362 *) The request to a remote proxy was mangled if it was generated as the
8363 result of a ProxyPass directive. URL schemes other than http:// were not
8364 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

8371 do for errors and cached responses. [Roy Fielding]
8373 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8375 Changes with Apache 1.2.2 [not released]
8377 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8378 happily skip past access checks on subdirectories looked up with relative
8379 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8382 *) Add lockfile name to error message printed out when
8383 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8386 *) Enhanced the chunking and error handling inside the buffer functions.
8387 [Dean Gaudet, Roy Fielding]

8390 a vhost, put the main server's first and the vhost's second. Otherwise
8391 the vhost can't override the main server. [Dean Gaudet] PR#717
8393 *) The <Directory> code would merge and re-merge the same section after
8394 a match was found, possibly causing problems with some modules.

8398 [Dean Gaudet] PR#748
8400 *) mod_include cleanup showed that handle_else was being used to handle
8401 endif. It didn't cause problems, but it was cleaned up too.
8404 *) Last official synchronization of mod_rewrite with author version (because
8405 mod_rewrite is now directly developed by the author at the Apache Group):
8406 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8407 minus WIN32/NT stuff, but plus copyright removement.
8409 - workaround for detecting infinite rewriting loops
8410 - fixed setting of env vars when "-" is used as subst string

8413 - kludge to disable locking on pipes under braindead SunOS
8414 - fix for rewritelog in cases where remote hostname is unknown
8415 - fixed totally damaged request_rec walk-back loop
8416 o remove static from local data and add static to global ones.
8417 o replaced ugly proxy finding stuff by simple
8418 find_linked_module("mod_proxy") call.

8506 *) Attempt to work around problems with third party libraries that do not
8507 handle high numbered descriptors (examples include bind, and
8508 solaris libc). On all systems apache attempts to keep all permanent
8509 descriptors above 15 (called the low slack line). Solaris users
8510 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8511 which keeps all non-FILE * descriptors above 255. On all systems
8512 this should make supporting large numbers of vhosts with many open
8513 log files more feasible. If this causes trouble please report it,
8514 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8515 [Dean Gaudet] various PRs
8517 *) Related to the last entry, network sockets are now opened before
8518 log files are opened. The only known case where this can cause
8519 problems is under Solaris with many virtualhosts and many Listen
8520 directives. But using -DHIGH_SLACK_LINE=256 described above will
8521 work around this problem. [Dean Gaudet]
8523 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8526 *) Improved unix error response logging. [Marc Slemko]
8528 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8529 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8530 when a URL http://... was used in conjunction with a special
8531 redirect flag, e.g. R=permanent, the permanent status was lost.

8576 reading from one buffer and writing to another, at least until it has
8577 a custom timeout handler. [Roy Fielding and Petr Lampa]

8593 [Chuck Murcko] PR#614
8595 *) If multiple requests on a single connection are used to retrieve

8612 *) If a soft_timeout occurs after keepalive is set, then the main child
8613 loop would try to read another request even though the connection

8616 *) Configure changes: Allow for whitespace at the start of a
8617 Module declaration. Also, be more understanding about the
8618 CC=/OPTIM= format in Configuration. Finally, fix compiler
8619 flags if using HP-UX's cc compiler. [Jim Jagielski]
8621 *) Subrequests and internal redirects now inherit the_request from the
8622 original request-line. [Roy Fielding]
8624 *) Test for error conditions before creating output header fields, since
8625 we don't want the error message to include those fields. Likewise,
8626 reset the content_language(s) and content_encoding of the response
8627 before generating or redirecting to an error message, since the new
8628 message will have its own Content-* definitions. [Dean Gaudet]
8630 *) Restored the semantics of headers_out (headers sent only with 200..299
8631 and 304 responses) and err_headers_out (headers sent with all responses).
8632 Avoid the overhead of copying tables if err_headers_out is empty
8633 (the usual case). [Roy Fielding]
8635 *) Fixed a couple places where a check for the default Content-Type was
8636 not properly checking both the value configured by the DefaultType
8637 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8638 of DEFAULT_TYPE to match the documented default (text/plain).

8641 *) Escape the HTML-sensitive characters in the Request-URI that is
8642 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8644 *) Properly initialize the flock structures used by the mutex locking
8645 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8648 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8649 (and NCSA httpd) definition wherein it was the extra path info beyond
8650 the CGI script filename. The environment variable FILEPATH_INFO has
8651 been removed, and instead we supply the original REQUEST_URI to any
8652 script that wants to be Apache-specific and needs the real URI path.
8653 This solves a problem with existing scripts that use extra path info
8654 in the ScriptAlias directive to pass options to the CGI script.
8657 *) The _default_ change in 1.2b10 will change the behaviour on configs
8658 that use multiple Listen statements for listening on multiple ports.
8659 But that change is necessary to make _default_ consistent with other
8660 forms of <VirtualHost>. It requires such configs to be modified
8661 to use <VirtualHost _default_:*>. The documentation has been
8662 updated. [Dean Gaudet] PR#530
8664 *) If an ErrorDocument CGI script is used to respond to an error
8665 generated by another CGI script which has already read the message
8666 body of the request, the server would block trying to read the
8667 message body again. [Rob Hartill]

8691 changes and in anticipation of 1.2 final release. [Roy Fielding]
8693 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8694 the connection (e.g., when user presses Stop). Apache will now stop
8695 trying to send a message body immediately after an error from write.
8696 [Roy Fielding and Nathan Kurz] PR#335
8698 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8699 than mod_alias, and mod_alias has higher priority than mod_proxy;
8700 rearranged other modules to enhance understanding of their purpose
8701 and relative order (and maybe even reduce some overhead).

8704 *) Fix graceful restart. Eliminate many signal-related race
8705 conditions in both forms of restart, and in SIGTERM. See
8706 htdocs/manual/stopping.html for details on stopping and
8707 restarting the parent. [Dean Gaudet]
8709 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8710 memory allocator to avoid a behaviour that required extra blocks to
8711 be allocated. [Dean Gaudet]
8713 *) Allow suexec to access files relative to current directory but not

8721 while obtaining the /~user and save the username in a separate data
8722 area so that it won't be overwritten by the call to getgrgid(), and
8723 fix some misuse of the pool string allocation functions. Also fixes
8724 a general problem with parsing URL query info into args for CGI scripts.

8734 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8736 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8737 object that can't be PUT, or FOOBAR for some method FOOBAR that
8738 apache doesn't know about at all). Log 404s that occur in mod_include.
8739 [Paul Sutton, John Van Essen]
8741 *) If a soft timeout (or lingerout) occurs while trying to flush a
8742 buffer or write inside buff.c or fread'ing from a CGI's output,
8743 then the timeout would be ignored. [Roy Fielding] PR#373
8745 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8746 parsing of headers. If the terminating empty-line CRLF occurs starting
8747 at the 256th or 257th byte of output, then Navigator will think a normal
8748 image is invalid. We are guessing that this is because their initial
8749 read of a new request uses a 256 byte buffer. We check the bytes written
8750 so far and, if we are about to tickle the bug, we instead insert a
8751 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8753 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8754 of an external redirection. [Roy Fielding and Paul Sutton]
8756 *) Configure would create a broken Makefile if the configuration file
8757 contained a commented-out Rule. [Roy Fielding]
8759 *) Promote per_dir_config and subprocess_env from the subrequest to the
8760 main request in mod_negotiation. In particular this fixes a bug
8761 where <Files> sections wouldn't properly apply to negotiated content.
8764 *) Fix a potential deadlock in mod_cgi script_err handling.
8765 [Ralf S. Engelschall]
8767 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8770 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8771 .htaccess files because the RewriteBase was not replaced correctly.
8772 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8773 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8775 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8776 1.x the settings are those of pre-1.2b8. For 2.x we include
8777 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8778 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8779 [Dean Gaudet] PR#336, PR#340
8781 *) Redirect did not preserve ?query_strings when present in the client's

8788 *) Add UnixWare compile/install instructions. [Chuck Murcko]

8792 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8794 *) Improve handling of directories when filenames have spaces in them.
8797 *) For hosts with multiple IP addresses, try all additional addresses if
8798 necessary to get a connect. Fail only if hostent address list is
8799 exhausted. [Chuck Murcko]
8801 *) More signed/unsigned port fixes. [Dean Gaudet]
8803 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8806 Changes with Apache 1.2b8
8808 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8809 to it. [Marc Slemko]
8811 *) The addition of <Location> and <File> directives made the
8812 sub_req_lookup_simple() function bogus, so we now handle
8813 the special cases directly. [Dean Gaudet]
8815 *) We now try to log where the server is dumping core when a fatal
8816 signal is received. [Ken Coar]
8818 *) Improved lingering_close by adding a special timeout, removing the
8819 spurious log messages, removing the nonblocking settings (they
8820 are not needed with the better timeout), and adding commentary
8821 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8822 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8824 *) Send error messages about setsockopt failures to the server error
8825 log instead of stderr. [Roy Fielding]
8827 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8829 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8830 processing a subrequest, allocate memory from r->main->pool instead
8831 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8832 in the middle of an SSI request. [Dean Gaudet] PR #122
8834 *) Fixed status of response when POST is received for a nonexistent URL
8835 (was sending 405, now 404) and when any method is sent with a
8836 full-URI that doesn't match the server and the server is not acting
8837 as a proxy (was sending 501, now 403). [Roy Fielding]
8839 *) Host port changed to unsigned short. [Ken Coar] PR #276
8841 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8843 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8845 *) Report extra info from errno with many errors that cause httpd to exit.
8846 spawn_child, popenf, and pclosef now have valid errno returns in the
8847 event of an error. Correct problems where errno was stomped on
8848 before being reported. [Dean Gaudet]
8850 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8851 never called, and thus the filesystem would remain full indefinitely.
8852 We now also remove incomplete cache files left if the origin server
8853 didn't send a Content-Length header and either the client has aborted
8854 transfer or bwrite() to client has failed. [Petr Lampa]
8856 *) Fixed the handling of module and script-added header fields.
8857 Improved the interface for sending header fields and reduced
8858 the duplication of code between sending okay responses and errors.
8859 We now always send both headers_out and err_headers_out, and
8860 ensure that the server-reserved fields are not being overridden,
8861 while not overriding those that are not reserved. [Roy Fielding]
8863 *) Moved transparent content negotiation fields to err_headers_out
8864 to reflect above changes. [Petr Lampa]
8866 *) Fixed the determination of whether or not we should make the
8867 connection persistent for all of the cases where some other part
8868 of the server has already indicated that we should not. Also
8869 improved the ordering of the test so that chunked encoding will
8870 be set whenever it is desired instead of only when KeepAlive
8871 is enabled. Added persistent connection capability for most error
8872 responses (those that do not indicate a bad input stream) when
8873 accessed by an HTTP/1.1 client. [Roy Fielding]
8875 *) Added missing timeouts for sending header fields, error responses,
8876 and the last chunk of chunked encoding, each of which could have
8877 resulted in a process being stuck in write forever. Using soft_timeout
8878 requires that the sender check for an aborted connection rather than
8879 continuing after an EINTR. Timeouts that used to be initiated before
8880 send_http_header (and never killed) are now initiated only within or
8881 around the routines that actually do the sending, and not allowed to
8882 propagate above the caller. [Roy Fielding]
8884 *) mod_auth_anon required an @ or a . in the email address, not both.
8887 *) per_dir_defaults weren't set correctly until directory_walk for
8888 name-based vhosts. This fixes an obscure bug with the wrong config
8889 info being used for vhosts that share the same ip as the server.
8892 *) Improved generation of modules/Makefile to be more generic for
8893 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8895 *) Generate makefile dependency for Configuration based on the actual
8896 name given when running the Configure process. [Dean Gaudet]
8898 *) Fixed problem with vhost error log not being set prior to
8899 initializing virtual hosts. [Dean Gaudet]
8901 *) Fixed infinite loop when a trailing slash is included after a type map
8902 file URL (extra path info). [Petr Lampa]
8904 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8906 *) Add documentation for DNS issues (reliability and security), and try
8907 to explain the virtual host matching process. [Dean Gaudet]
8909 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8910 fails while parsing the configuration file. [Dean Gaudet]
8912 *) Improved calls to setsockopt. [Roy Fielding]
8914 *) Negotiation changes: Don't output empty content-type in variant list;
8915 Output charset in variant list; Return sooner from handle_multi() if
8916 no variants found; Add handling of '*' wildcard in Accept-Charset.
8917 [Petr Lampa and Paul Sutton]
8919 *) Fixed overlaying of request/sub-request notes and headers in
8920 mod_negotiation. [Dean Gaudet]
8922 *) If two variants' charset quality are equal and one is the default
8923 charset (iso-8859-1), then prefer the variant that was specifically
8924 listed in Accept-Charset instead of the default. [Petr Lampa]
8926 *) Memory allocation problem in push_array() -- it would corrupt memory
8927 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8929 *) invoke_handler() doesn't handle mime arguments in content-type
8932 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8935 *) Fixed problem with ErrorDocument not working for virtual hosts
8936 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8938 *) Log an error message if we get a request header that is too long,
8939 since it may indicate a buffer overflow attack. [Marc Slemko]
8941 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8942 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8943 [Ken Coar] PR #146, #187

8949 [Garey Smiley] PR #59
8951 *) Fixed error message when resource is not found and URL contains
8952 path info. [Petr Lampa and Dean Gaudet] PR #40
8954 *) Fixed user and server confusion over what should be a virtual host
8955 and what is the main server, resulting in access to something
8956 other than the name defined in the virtualhost directive (but
8957 with the same IP address) failing. [Dean Gaudet]
8959 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8960 AIX; improves the redirection stuff to enable the users to generally
8961 redirect to http, https, gopher and ftp; added TIME variable for
8962 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8963 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8964 can be used in conjunction with %{TIME} or other variables to create
8965 time-dependent rewriting rules. [Ralf S. Engelschall]
8967 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8968 Module authors may need to adjust their code for proper cleanup to take
8969 place (that is, call note_cleanups_for_fd()). This change fixes problems
8970 with file descriptors being erroneously closed when the proxy module was
8971 in use. [Ben Laurie]
8973 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8974 initgroups() to hose the group information needed for later
8975 comparisons. [Randy Terbush]
8977 *) Remove unnecessary call to va_end() in create_argv() which
8978 caused a SEGV on some systems.
8980 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8983 *) Clear memory allocated for listeners. [Randy Terbush]

9012 perhaps questionable, they appear to be legal by RFC 959.

9042 the socket is not connected (reset by client). [Roy Fielding]
9044 *) Rearranged main child loop to remove duplication of code in
9045 select/accept and keep-alive requests, fixed several bugs regarding
9046 checking scoreboard_image for exit indication and failure to
9047 account for all success conditions and trap all error conditions,
9048 prevented multiple flushes before closing the socket; close the entire
9049 socket buffer instead of just one descriptor, prevent logging of
9050 EPROTO and ECONNABORTED on platforms where supported, and generally
9051 improved readability. [Roy Fielding]
9053 *) Extensive performance improvements. Cleaned up inefficient use of
9054 auto initializers, multiple is_matchexp calls on a static string,
9055 and excessive merging of response_code_strings. [Dean Gaudet]
9057 *) Added double-buffering to mod_include to improve performance on
9058 server-side includes. [Marc Slemko]
9060 *) Several fixes for suexec wrapper. [Randy Terbush]
9061 - Make wrapper work for files on NFS filesystem.
9062 - Fix portability problem of MAXPATHLEN.
9063 - Fix array overrun problem in clean_env().
9064 - Fix allocation of PATH environment variable
9066 *) Removed extraneous blank line is description of mod_status chars.
9069 *) Logging of errors from the call_exec routine simply went nowhere,
9070 since the logfile fd has been closed, so now we send them to stderr.
9071 [Harald T. Alvestrand]
9073 *) Fixed core dump when DocumentRoot is a CGI.
9074 [Ben Laurie, reported by geddis@tesserae.com]
9076 *) Fixed potential file descriptor leak in mod_asis; updated it and
9077 http_core to use pfopen/pfclose instead of fopen/fclose.
9078 [Randy Terbush and Roy Fielding]
9080 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
9081 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9082 [Dean Gaudet and Ken Coar]
9084 *) Return a 302 response code to the client when sending a redirect
9085 due to a missing trailing '/' on a directory instead of a 301; now
9086 it is cacheable. [Markus Gyger]
9088 *) Fix condition where, if a bad directive occurs in .htaccess, and
9089 sub_request() goes first to this directory, then log_reason() will
9090 SIGSEGV because it doesn't have initialized r->per_dir_config.
9091 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9093 *) Fix handling of lang_index in is_variant_better(). This was
9094 causing problems which resulted in the server sending the
9095 wrong language document in some cases. [Petr Lampa]
9097 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9098 the clean environment on some systems.
9100 *) Tweak byteserving code (e.g. serving PDF files) to work around
9101 bugs in Netscape Navigator and Microsoft Internet Explorer.
9102 Emit Content-Length header when sending multipart/byteranges.
9105 *) Port to HI-UX/WE2. [Nick Maclaren]
9107 *) Port to HP MPE operating system for HP 3000 machines
9108 [Mark Bixby <markb@cccd.edu>]
9110 *) Fixed bug which caused a segmentation fault if only one argument
9111 given to RLimit* directives. [Ed Korthof]
9113 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9115 *) Improved buffered output to the client by delaying the flush decision
9116 until the BUFF code is actually about to read the next request.
9117 This fixes a problem introduced in 1.2b5 with clients that send
9118 an extra CRLF after a POST request. Also improved chunked output
9119 performance by combining writes using writev() and removing as
9120 many bflush() calls as possible. NOTE: Platforms without writev()
9121 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9122 or Configure, unless we have already done so. [Dean Gaudet]
9124 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9126 *) Fixed mod_info output corruption bug introduced by buffer overflow
9127 fixes. [Dean Gaudet]
9129 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9130 for the special case of a 304 response. [Paul Sutton]
9132 *) Improved handling of TRACE method by bypassing normal method handling
9133 and header parsing routines; fixed Allow response to always allow TRACE.
9136 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9138 *) Cleaned-up some of the generated HTML. [Ken Coar]
9140 Changes with Apache 1.2b6
9142 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9144 *) Fix typo introduced in fix for potential infinite loop around
9145 accept() in child_main(). This change caused the rev to 1.2b6.
9146 1.2b5 was never a public beta.
9148 Changes with Apache 1.2b5
9150 *) Change KeepAlive semantics (On|Off instead of a number), add
9151 MaxKeepAliveRequests directive. [Alexei Kosut]
9153 *) Various NeXT compilation patches, as well as a change in
9154 regex/regcomp.c since that file also used a NEXT define.
9157 *) Allow * to terminate the end of a directory match in mod_dir.
9158 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9160 *) Don't call can_exec() if suexec_enabled. Calling this requires
9161 scripts executed by the suexec wrapper to be world executable, which
9162 defeats one of the advantages of running the wrapper. [Randy Terbush]
9164 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9167 *) Migration from sprintf() to snprintf() to avoid buffer
9168 overflows. [Marc Slemko]
9170 *) Provide portable snprintf() implementation (ap_snprintf)
9171 as well as *cvt family. [Jim Jagielski]
9173 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9176 *) Remove mod_fastcgi.c from the distribution. This module appears
9177 to be maintained more through the Open Market channels and should
9178 continue to be easily available at http://www.fastcgi.com/
9180 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9181 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9183 *) mod_info assumed that the config files were relative to ServerRoot.
9186 *) CGI scripts called as an error document resulting from failed
9187 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9189 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9192 *) Properly check errno to prevent display of a directory index
9193 when server receives a long enough URL to confuse stat().
9196 *) Several security enhancements to suexec wrapper. It is _highly_
9197 recommended that previously installed versions of the wrapper
9198 be replaced with this version. [Randy Terbush, Jason Dour]
9200 - ~user execution now properly restricted to ~user's home
9201 directory and below.
9202 - execution restricted to UID/GID > 100
9203 - restrict passed environment to known variables
9204 - call setgid() before initgroups() (portability fix)
9205 - remove use of setenv() (portability fix)
9207 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9209 *) Add access control via environment variables. [Ben Laurie]
9211 *) Add rflush() function. [Alexei Kosut]
9213 *) remove duplicate pcalloc() call in new_connection().
9215 *) Fix incorrect comparison which could allow number of children =
9216 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9217 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9219 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9220 AIX PS/2, CONVEXOS. [Jim Jagielski]
9222 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9223 It's more portable. [Martin Kraemer]
9225 *) Replace references to make in Makefile.tmpl with $(MAKE).
9228 *) Add ProxyBlock directive w/IP address caching. Add IP address
9229 caching to NoCache directive as well. ProxyBlock works with all
9230 handlers; NoCache now also works with FTP for anonymous logins.
9231 Still more code cleanup. [Chuck Murcko]
9233 *) Add "header parse" API hook [Ben Laurie]
9235 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9237 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9239 *) Correctly allow access and auth directives in <Files> sections in
9240 server config files. [Alexei Kosut]
9242 *) Fix bug with ServerPath that could cause certain files to be not
9243 found by the server. [Alexei Kosut]
9245 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9246 double-quote from text and so that it properly checks for unsupported
9247 status codes using the new index_of_response interface. [Roy Fielding]
9249 *) Multiple fixes to the lingering_close code in order to avoid being
9250 interrupted by a stray timeout, to avoid lingering on a connection
9251 that has already been aborted or never really existed, to ensure that
9252 we stop lingering as soon as any error condition is received, and to
9253 prevent being stuck indefinitely if the read blocks. Also improves
9254 reporting of error conditions. [Marc Slemko and Roy Fielding]
9256 *) Fixed initialization of parameter structure for sigaction.
9257 [mgyger@itr.ch, Adrian Filipi-Martin]
9259 *) Fixed reinitializing the parameters before each call to accept and
9260 select, and removed potential for infinite loop in accept.
9261 [Roy Fielding, after useful PR from adrian@virginia.edu]
9263 *) Fixed condition where, if a child fails to fork, the scoreboard would
9264 continue to say SERVER_STARTING forever. Eventually, the main process
9265 would refuse to start new children because count_idle_servers() will
9266 count those SERVER_STARTING entries and will always report that there
9267 are enough idle servers. [Phillip Vandry]
9269 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9270 Avoided calling bflush() when the client is pipelining requests.
9271 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9273 *) Added description of "." mode in server-status [Jim Jagielski]
9275 Changes with Apache 1.2b4
9277 *) Fix possible race condition in accept_mutex_init() that
9278 could leave a small security hole open allowing files to be
9279 overwritten in cases where the server UID has write permissions.
9282 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9284 *) Fix portablity problem in util_script where ARG_MAX may not be
9285 defined for some systems.
9287 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9290 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9291 style magic #! token for better script portability. [Garey Smiley]
9293 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9294 execution for ~userdir CGI. [Jason Dour]
9296 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9298 *) Fix month off by one in suexec wrapper logging.
9300 Changes with Apache 1.2b3:
9302 *) Fix error in mod_cgi which could cause resources not to be properly
9303 freed, or worse. [Dean Gaudet]
9305 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9307 *) Add set_flag_slot() at the request of Dirk and others.
9310 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9312 *) Add changes to improve the error message given for invalid
9313 ServerName parameters. [Dirk vanGulik]
9315 *) Add "Authoritative" directive for Auth modules that don't
9316 currently have it. This gives admin control to assign authoritative
9317 control to an authentication scheme and allow "fall through" for
9318 those authentication modules that aren't "Authoritative" thereby
9319 allowing multiple authentication mechanisms to be chained.
9322 *) Remove requirement for ResourceConfig/AccessConfig if not using
9323 the three config file layout. [Randy Terbush]
9325 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9327 *) Changes to suexec wrapper to fix the following problems:
9328 1. symlinked homedirs will kill ~userdirs.
9329 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9330 3. CGI command lines paramters problems
9331 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9332 [Randy Terbush, Jason Dour]
9334 *) Change create_argv() to accept variable arguments. This fixes
9335 a problem where arguments were not getting passed to the CGI via
9336 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9338 *) Collapse multiple slashes in path URLs to properly apply
9339 handlers defined by <Location>. [Alexei Kosut]
9341 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9343 *) Improve the accuracy of request duration timings by setting
9344 r->request_time in read_request_line() instead of read_request().
9347 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9348 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9350 *) Add the ability to pass different Makefile.tmpl files to Configure
9351 using the -make flag. [Rob Hartill]
9353 *) Fix coredump triggered when sending a SIGHUP to the server caused
9354 by an assertion failure, in turn caused by an uninitialised field in a
9358 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9359 PATH_INFO from previous versions of Apache (in certain situations,
9360 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9361 [later removed in 1.2b11]
9363 *) Add rwrite() function to API to allow for sending strings of
9364 arbitrary length. [Doug MacEachern]
9366 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9368 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9369 NeXT. [Jim Jagielski]
9371 *) Removed recent modification to promote the status code on internal
9372 redirects, since the correct fix was to change the default log format
9373 in mod_log_config so that it outputs the original status. [Rob Hartill]
9375 Changes with Apache 1.2b2:
9377 *) Update set_signals() to use sigaction() for setting handlers.
9378 This appears to fix a re-entrant problem in the seg_fault()
9379 bus_error() handlers. [Randy Terbush]
9381 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9383 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9385 *) proxy_http.c bugfixes: [Chuck Murcko]
9386 1) fixes possible NULL pointer reference w/NoCache
9387 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9388 host would cache nothing if it was in the local domain,
9389 and the local domain was in the NoCache list)
9390 3) Adds Host: header when not available
9391 4) Some code cleanup and clarification
9393 *) mod_include.c bugfixes:
9394 1) Fixed an ommission that caused include variables to not
9395 be parsed in config errmsg directives [Howard Fear]
9396 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9397 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9398 4) Allow backslash-escaping to all quoted text
9399 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9400 5) Pass variable to command line if not set in XSSI's env
9403 *) Fix infinite loop when processing Content-language lines in
9404 type-map files. [Alexei Kosut]
9406 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9408 *) Fixed problem in set_[user|group] that prevented CGI execution
9409 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9411 *) Added PORTING information file. [Jim Jagielski]
9413 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9415 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9417 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9418 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9420 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9421 which caused problems of systems where socket s_addr is >32bits.
9423 *) Added comment to explain (r->chunked = 1) side-effect in
9424 http_protocol.c [Roy Fielding]
9426 *) Replaced use of index() in mod_expires.c with more appropriate
9427 and portable isdigit() test. [Ben Laurie]
9429 *) Updated Configure for ...
9430 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9431 *-dg-dgux* (bad pattern match)
9432 QNX (DEF_WANTHSREGEX=yes)
9433 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9436 and added some user diagnostic info. [Ben Laurie]
9438 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9439 for better portability. [Jim Jagielski]
9441 *) Updated helpers/GuessOS for ...
9442 SCO 5 (recognize minor releases)
9443 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9444 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9445 IRIX64 (-sgi-irix64)
9446 ULTRIX (-unknown-ultrix)
9447 SINIX (-whatever-sysv4)
9448 NCR Unix (-ncr-sysv4)
9449 and fixed something in helpers/PrintPath [Ben Laurie]
9451 Changes with Apache 1.2b1
9453 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9455 Changes with Apache 1.1.1
9457 *) Fixed bug where Cookie module would make two entries in the
9458 logfile for each access [Mark Cox]
9460 *) Fixed bug where Redirect in .htaccess files would cause memory
9461 leak. [Nathan Neulinger]
9463 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9465 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9467 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9469 Changes with Apache 1.1.0
9471 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9473 *) Bring QNX support up to date. [Ben Laurie]
9475 *) Make virtual hosts default to main server keepalive parameters.
9476 [Alexei Kosut, Ben Laurie]
9478 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9480 *) Fix missing address family for connect, also remove unreachable statement
9481 in mod_proxy. [Ben Laurie]
9483 *) mod_env now turned on by default in Configuration.tmpl.
9485 *) Bugs which were fixed:
9486 a) yet more mod_proxy bugs [Ben Laurie]
9487 b) CGI works again with inetd [Alexei Kosut]
9488 c) Leading colons were stripped from passwords [osm@interguide.com]
9489 d) Another fix to multi-method Limit problem [jk@tools.de]
9491 Changes with Apache 1.1b4
9493 *) r->bytes_sent variable restored. [Robert Thau]
9495 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9497 *) More possibly unsecure programs removed from the support directory.
9499 *) More mod_auth_msql authentication improvements.
9501 *) VirtualHosts based on Host: headers no longer conflict with the
9504 *) OS/2 compatibility enhancements. [Gary Smiley]
9506 *) POST now allowed to directory index CGI scripts.
9508 *) Actions now work with files of the default type.
9510 *) Bugs which were fixed:
9511 a) more mod_proxy bugs
9512 b) early termination of inetd requests
9513 c) compile warnings on several systems
9514 d) problems when scripts stop reading output early
9516 Changes with Apache 1.1b3
9518 *) Much of cgi-bin and all of cgi-src has been removed, due to
9519 various security holes found and that we could no longer support
9522 *) The "Set-Cookie" header is now special-cased to not merge multiple
9523 instances, since certain popular browsers can not handle multiple
9524 Set-Cookie instructions in a single header. [Paul Sutton]
9526 *) rprintf() added to buffer code, occurrences of sprintf removed.
9529 *) CONNECT method for proxy module, which means tunneling SSL should work.
9530 (No crypto needed) Also a NoCache config directive.
9532 *) Several API additions: pstrndup(), table_unset() and get_token()
9533 functions now available to modules.
9535 *) mod_imap fixups, in particular Location: headers are now complete
9538 *) New "info" module which reports on installed module set through a
9539 special URL, a la mod_status.
9541 *) "ServerPath" directive added - allows for graceful transition
9542 for Host:-header-based virtual hosts.
9544 *) Anonymous authentication module improvements.
9546 *) MSQL authentication module improvements.
9548 *) Status module design improved - output now table-based. [Ben Laurie]
9550 *) htdigest utility included for use with digest authentication
9553 *) mod_negotiation: Accept values with wildcards to be treated with
9554 less priority than those without wildcards at the same quality
9555 value. [Alexei Kosut]
9557 *) Bugs which were fixed:
9558 a) numerous mod_proxy bugs
9559 b) CGI early-termination bug [Ben Laurie]
9560 c) Keepalives not working with virtual hosts
9561 d) RefererIgnore problems
9562 e) closing fd's twice in mod_include (causing core dumps on
9563 Linux and elsewhere).
9565 Changes with Apache 1.1b2
9568 a) core dumps in mod_digest
9569 b) truncated hostnames/ip address in the logs
9570 c) relative URL's in mod_imap map files
9572 Changes with Apache 1.1b1
9574 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9576 Changes with Apache 1.0.3
9578 *) Internal redirects which occur in mod_dir.c now preserve the
9579 query portion of a request (the bit after the question mark).
9582 *) Escape active characters '<', '>' and '&' in html output in
9583 directory listings, error messages and redirection links.
9586 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9588 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9591 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9593 *) Reset timeout timer after each successful fwrite() to the network.
9594 This patch adds a reset_timeout() procedure that is called by
9595 send_fd() to reset the timeout ever time data is written to the net.
9598 *) timeout() signal handler now checks for SIGPIPE and reports
9599 lost connections in a more user friendly way. [Rob Hartill]
9601 *) Location of the "scoreboard" file which used to live in /tmp is
9602 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9603 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9605 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9607 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9608 which caused a SEGV with cookies enabled
9610 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9613 *) Log the UNIX textual error returned by some system calls, in
9614 particular errors from accept() [David Robinson]
9616 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9618 Changes with Apache 1.0.2
9620 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9621 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9623 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9626 *) past changes to http_config.c to only use the
9627 setrlimit function on systems defining RLIMIT_NOFILE
9628 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9629 for SUNOS and prototypes the needed functions.
9631 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9634 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9636 *) Merge multiple headers from CGI scripts instead of taking last
9637 one. [David Robinson]
9639 *) Add support for SCO 5. [Ben Laurie]
9641 Changes with Apache 1.0.1
9643 *) Silence mod_log_referer and mod_log_agent if not configured
9646 *) Recursive includes can occur if the client supplies PATH_INFO data
9647 and the server provider uses relative links; as file.html
9648 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9650 *) The replacement for initgroups() did not call {set,end}grent(). This
9651 had two implications: if anything else used getgrent(), then
9652 initgroups() would fail, and it was consuming a file descriptor.
9655 *) On heavily loaded servers it was possible for the scoreboard to get
9656 out of sync with reality, as a result of a race condition.
9657 The observed symptoms are far more Apaches running than should
9658 be, and heavy system loads, generally followed by catastrophic
9659 system failure. [Ben Laurie]
9661 *) Fix typo in license. [David Robinson]
9663 Changes with Apache 1.0.0 23 Nov 1995
9665 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9667 Changes with Apache 0.8.16 05 Nov 1995
9669 *) New man page for 'httpd' added to support directory [David Robinson]
9671 *) .htgroup files can have more than one line giving members for a
9672 given group (each must have the group name in front), for NCSA
9673 back-compatibility [Robert Thau]
9675 *) Mutual exclusion around accept() is on by default for SVR4 systems
9676 generally, since they generally can't handle multiple processes in
9677 accept() on the same socket. This should cure flaky behavior on
9678 a lot of those systems. [David Robinson]
9680 *) AddType, AddEncoding, and AddLanguage directives take multiple
9681 extensions on a single command line [David Robinson]
9683 *) UserDir can be disabled for a given virtual host by saying
9684 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9685 that this didn't work. [David Robinson]
9687 *) Compiles on QNX [Ben Laurie]
9689 *) Corrected parsing of ctime time format [David Robinson]
9691 *) httpd does a perror() before exiting if it can't log its pid
9692 to the PidFile, to make diagnosing the error a bit easier.
9695 *) <!--#include file="..."--> can no longer include files in the
9696 parent directory, for NCSA back-compatibility. [David Robinson]
9698 *) '~' is *not* escaped in URIs generated for directory listings
9701 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9703 *) Fixed bug involving handling URIs with escaped %-characters
9704 in redirects [David Robinson]
9706 Changes with Apache 0.8.15 14 Oct 1995
9708 *) Switched to new, simpler license
9710 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9712 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9714 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9716 *) Correctly handles internal redirects to files with names containing '%'
9719 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9721 *) Use geteuid() rather than getuid() to see if we have root privilege,
9722 so that server correctly resets privilege if run setuid root. [Andrew
9725 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9728 *) Fix relative URLs in imagemap files [Randy Terbush]
9730 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9733 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9734 entries all name the same one. [David Robinson]
9736 *) Fix directory listings with filenames containing unusual characters
9739 *) Better URI-escaping for generated URIs in directories with filenames
9740 containing unusual characters [Ben Laurie]
9742 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9744 *) Unblock alarms on error return from spawn_child() [David Robinson]
9746 *) Sample Config files have extra note for SCO users [Ben Laurie]
9748 *) Configuration has note for HP-UX users [Rob Hartill]
9750 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9752 *) Nuked bogus #define in httpd.h [David Robinson]
9754 *) Better test for whether a system has setrlimit() [David Robinson]
9756 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9758 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9761 Changes with Apache 0.8.14 19 Sep 1995
9763 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9765 *) AddDescription works (better) [Ben Laurie]
9767 *) Leaves an intelligible error diagnostic when it can't set group
9768 privileges on standalone startup [Andrew Wilson]
9770 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9771 that machine, which claims to be BSD but does not support RLIMIT.
9774 *) gcc -Wall no longer complains about an unused variable when util.c
9775 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9777 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9779 Changes with Apache 0.8.13 07 Sep 1995
9781 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9783 *) Have built-in imagemap code recognize & honor Point directive [James
9786 *) Generate cleaner directory listings in directories with a mix of
9787 long and short filenames [Rob Hartill]
9789 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9791 *) Properly default ServerName for virtual servers [Robert Thau]
9793 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9794 Paul Richards and a cast of thousands...]
9796 *) On self-identified BSD systems (we don't try to guess any more),
9797 allocate a few extra file descriptors per virtual host with setrlimit,
9798 if we can, to avoid running out. [Randy Terbush]
9800 *) Write 22-character lock file name into buffer with enough space
9801 on startup [Konstantin Olchanski]
9803 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9806 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9808 *) Suppress -Wall warning by initializing variable in negotiation code
9809 [Tobias Weingartner]
9811 Changes with Apache 0.8.12 31 Aug 1995
9813 *) Doesn't pause three seconds after including a CGI script which is
9814 too slow to die off (this is done by not even trying to kill off
9815 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9816 after the entire document has been processed). [Robert Thau]
9818 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9820 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9822 *) Allows .htaccess files to override <Directory> sections naming the
9823 same directory [David Robinson]
9825 *) Removed an efficiency hack in sub_req_lookup_uri which was
9826 causing certain extremely marginal cases (e.g., ScriptAlias of a
9827 *particular* index.html file) to fail. [David Robinson]
9829 *) Doesn't log an error when the requested URI requires
9830 authentication, but no auth header line was supplied by the
9831 client; this is a normal condition (the client doesn't no auth is
9832 needed here yet). [Robert Thau]
9834 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9836 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9838 *) RFC931 code no longer passes out name of prior clients on current
9839 requests if the current request came from a server that doesn't
9840 do RFC931. [David Robinson]
9842 *) Configuration script accepts "Module" lines with trailing whitespace.
9845 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9847 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9849 Changes with Apache 0.8.11 24 Aug 1995
9851 *) Wildcard <Directory> specifications work. [Robert Thau]
9853 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9855 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9856 the file being requested itself, in addition to the directories leading
9857 up to it. [Robert Thau]
9859 *) Logs access failures due to symlink checks or invalid client address
9860 in the error log [Roy Fielding, Robert Thau]
9862 *) Symlink checks deal correctly with systems where lstat of
9863 "/path/to/some/link/" follows the link. [Thau, Fielding]
9865 *) Doesn't reset DirectoryIndex to 'index.html' when
9866 other directory options are set in a .htaccess file. [Robert Thau]
9868 *) Clarified init code and nuked bogus warning in mod_access.c
9871 *) Corrected several directives in sample srm.conf
9872 --- includes corrections to directory indexing icon-related directives
9873 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9874 icons for encodings right, and turning on AddEncoding by default).
9877 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9880 *) INSTALL & README mention "contributed modules" directory [Brian
9883 *) Fixed English in the license language... "for for" --> "for".
9886 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9887 mod_alias.c, merging it almost completely with handling of Alias, and
9888 adding a 'notes' field to the request_rec which allows the CGI module
9889 to discover whether the Alias module has put this request through
9890 ScriptAlias (which it needs to know for back-compatibility, as the old
9891 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9894 Changes with Apache 0.8.10 18 Aug 1995
9896 *) AllowOverride applies to the named directory, and not just
9897 subdirectories. [David Robinson]
9899 *) Do locking for accept() exclusion (on systems that need it)
9900 using a special file created for the purpose in /usr/tmp, and
9901 not the error log; using the error log causes real problems
9902 if it's NFS-mounted; this is known to be the cause of a whole
9903 lot of "server hang" problems with Solaris. [David Robinson;
9904 thanks to Merten Schumann for help diagnosing the problem].
9906 Changes with Apache 0.8.9 12 Aug 1995
9908 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9910 *) Nested includes see environment variables of the including document,
9911 for NCSA bug-compatibility (some sites have standard footer includes
9912 which try to print out the last-modified date). [Eric Hagberg/Robert
9915 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9916 URI as a CGI script, even if it would have been treated as something
9917 else if requested directly, for NCSA back-compatibility. (Note that
9918 this means that people who know the name of the script can see the
9919 code just by asking for it). [Robert Thau]
9921 *) New version of dbmmanage script included in support directory as
9924 *) Check if scoreboard file couldn't be opened, and say so, rather
9925 then going insane [David Robinson]
9927 *) POST to CGI works on A/UX [Jim Jagielski]
9929 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9931 *) NCSA server push works properly --- the Arena bug compatibility
9932 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9933 if you still want the workaround). [Rob Hartill]
9935 *) If client didn't submit any Accept-encodings, ignore encodings in
9936 content negotiation. (NB this will all have to be reworked anyway
9937 for the new HTTP draft). [Florent Guillaume]
9939 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9941 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9943 *) Give Redirect priority over Alias, for NCSA bug compatibility
9946 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9947 paralleling earlier bug fix for CGI [David Robinson]
9949 *) If DBM auth is improperly configured, report a server error and don't
9952 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9953 it seems to work well enough without it (even in a 10 hits/sec
9954 workout), and the overhead for the locking under A/UX is
9955 alarmingly high (though it is very low on other systems).
9956 [Eric Hagberg, Jim Jagielski]
9958 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9960 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9961 Behlendorf/Eric Hagberg]
9963 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9965 *) Compiles clean on NEXT [Rob Hartill]
9967 *) Compiles clean on SGI [Robert Thau]
9969 Changes with Apache 0.8.8 08 Aug 1995
9971 *) SunOS library prototypes now never included unless explicitly
9972 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9973 people using GNU libc on SunOS are screwed by prototypes for the
9976 (Those who wish to compile clean with gcc -Wall on a standard
9977 SunOS setup need the prototypes, and may obtain them using
9978 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9979 with nonstandard libraries are presumably competent to make their
9982 *) Strips trailing '/' characters off both args to the Alias command,
9983 to make 'Alias /foo/ /bar/' work.
9985 Changes with Apache 0.8.7 03 Aug 1995
9987 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9988 [reported by David Robinson]
9990 *) Compiles clean on OSF/1 [David Robinson]
9992 *) Added some of the more recent significant changes (AddLanguage stuff,
9993 experimental LogFormat support) to CHANGES file in distribution root
9996 Changes with Apache 0.8.6 02 Aug 1995
9998 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9999 (If you actually wanted a conditional GET which bypassed the cache, you
10000 couldn't get it). [Reported by Roy Fielding]
10002 *) Properly terminate headers on '304 Not Modified' replies to conditional
10003 GETs --- no browser we can find cares much, but the CERN proxy chokes.
10004 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
10006 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
10008 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
10009 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
10010 and older versions don't set the __SUNPRO_C preprocessor variable). On
10011 all other systems, these are never used anyway. [Reported by Mark Cox].
10013 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
10015 Changes with Apache 0.8.5 01 Aug 1995
10017 *) Added last-minute configurable log experiment, as optional module
10019 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
10020 properly. (One-line fix to http_protocol.c).
10022 *) Work around bogus behavior when reloading from Netscape.
10023 It's Netscape's bug --- for some reason they expect a request with
10024 If-modified-since: to not function as a conditional GET if it also
10025 comes with Pragma: no-cache, which is way out of line with the HTTP
10026 spec (according to Roy Fielding, the redactor).
10028 *) Added parameter to set maximum number of server processes.
10030 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
10033 *) IdentityCheck bugfix [Chuck Murcko].
10035 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10037 *) More sample config file corrections; add extension to AddType for
10038 *.asis, move AddType generic description to its proper place, and
10039 fix miscellaneous typos. [ Alexei Kosut ]
10041 *) Deleted the *other* reference to the regents from the Berkeley
10042 legal disclaimer (everyplace).
10044 *) Nuked Shambhala name from src/README; had already cleaned it out
10045 of everywhere else.
10047 Changes with Apache 0.8.4
10049 *) Changes to server-pool management parms --- renamed current
10050 StartServers to MinSpareServers, created separate StartServers
10051 parameter which means what it says, and renamed MaxServers to
10052 MaxSpareServers (though the old name still works, for NCSA 1.4
10053 back-compatibility). The old names were generally regarded as
10054 too confusing. Also altered "docs" in sample config files.
10056 *) More improvements to default config files ---
10057 sample directives (commented out) for XBitHack, BindAddress,
10058 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10059 defaults, AddTypes for send-as-is and imagemap magic types, and
10060 improvements to samples for DirectoryIndex [Alexei Kosut]
10062 *) Yet more improvements to default config files --- changes to
10063 Alexei's sample AddLanguage directives, and sample LanguagePriority
10064 [ Florent Guillaume ]
10066 *) Set config file locations properly if not set in httpd.conf
10069 *) Don't escape URIs in internal redirects multiple times; don't
10070 do that when translating PATH_INFO to PATH_TRANSLATED either.
10073 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10075 Changes with Apache 0.8.3
10077 *) Edited distribution README to *briefly* summarize installation
10078 procedures, and give a pointer to the INSTALL file in the src/
10081 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10082 recent NCSA distributions.
10084 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10085 exist for the same directory, use both and don't segfault. [Reported
10088 *) Proper makefile dependencies [David Robinson]
10090 *) Note (re)starts in error log --- reported by Rob Hartill.
10092 *) Only call no2slash() after get_path_info() has been done, to
10093 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10094 reported by Andrew Wilson, though this one is probably a real bug]
10096 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10097 dump core when Referer is not supplied. [Randy Terbush]
10099 *) Lightly edited sample config files to refer people to our documentation
10100 instead of NCSA's, and to list Rob McCool as *original* author (also
10101 deleted his old, and no doubt non-functional email address). Would be
10102 nice to have examples of new features...
10104 Changes with Apache 0.8.2 19 Jul 1995
10106 *) Added AddLanuage code [Florent Guillaume]
10108 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10110 *) All sorts of problems when MultiViews finds a directory. It would
10111 be nice if mod_dir.c was robust enough to handle that, but for now,
10112 just punt. [reported by Brian Behlendorf]
10114 *) Wait for all children on restart, to make sure that the old socket
10115 is gone and we can reopen it. [reported by Randy Terbush]
10117 *) Imagemap module is enabled in default Configuration
10119 *) RefererLog and UserAgentLog modules properly default the logfile
10122 *) Mark Cox's mod_cookies added to the distribution as an optional
10123 module (commented out in the default Configuration, and noted as
10124 an experiment, along with mod_dld). [Mark Cox]
10126 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10128 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10130 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10132 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10135 Changes with Apache 0.8.1
10137 *) New imagemap module [Randy Terbush]
10139 *) Replacement referer log module with NCSA-compatible RefererIgnore
10140 [Matthew Gray again]
10142 *) Don't mung directory listings with very long filenames.
10143 [Florent Guillaume]
10145 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10147 *) New config script. See INSTALL for info. [Robert Thau]
10149 *) Scoreboard mechanism for regulating the number of extant server
10150 processes. MaxServers and StartServers defaults are the same as
10151 for NCSA, but the meanings are slightly different. (Actually,
10152 I should probably lower the MaxServers default to 10).
10154 Before asking for a new connection, each server process checks
10155 the number of other servers which are also waiting for a
10156 connection. If there are more than MaxServers, it quietly dies
10157 off. Conversely, every second, the root, or caretaker, process
10158 looks to see how many servers are waiting for a new connection;
10159 if there are fewer than StartServers, it starts a new one. This
10160 does not depend on the number of server processes already extant.
10161 The accounting is arranged through a "scoreboard" file, named
10162 /tmp/htstatus.*, on which each process has an independent file
10163 descriptor (they need to seek without interference).
10165 The end effect is that MaxServers is the maximum number of
10166 servers on an *inactive* server machine, but more will be forked
10167 off to handle unusually heavy loads (or unusually slow clients);
10168 these will die off when they are no longer needed --- without
10169 reverting to the overhead of full forking operation. There is a
10170 hard maximum of 150 server processes compiled in, largely to
10171 avoid forking out of control and dragging the machine down.
10172 (This is arguably too high).
10174 In my server endurance tests, this mechanism did not appear to
10175 impose any significant overhead, even after I forced it to put the
10176 scoreboard file on a normal filesystem (which might have more
10177 overhead than tmpfs). [Robert Thau]
10179 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10182 *) Read .htaccess files even in directory with <Directory> section.
10183 (Former incompatibility noted on mailing list, now fixed). [Robert
10186 *) "HEAD /" gives the client a "Bad Request" error message, rather
10187 than trying to send no body *and* no headers. [Cliff Skolnick].
10189 *) Don't produce double error reports for some very obscure cases
10190 mainly involving auth configuration (the "all modules decline to
10191 handle" case which is a sure sign of a server bug in most cases,
10192 but also happens when authentication is badly misconfigured).
10195 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10196 it's *for*, and this sort of thing really shouldn't be cluttering
10197 up the Makefile). [Robert Thau]
10199 *) Incidental code cleanups in http_main.c --- stop dragging
10200 sa_client around; just declare it where used. [Robert Thau]
10202 *) Another acc-related fix. (It doesn't like const char
10203 in some places...). [Mark Cox]
10205 Changes with Shambhala 0.6.1 13 Jul 1995
10207 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10208 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10210 *) Compiles clean with acc on SunOS [Paul Sutton]
10212 *) Reordered modules in modules.c so that Redirect takes priority
10213 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10214 believe it or not, he has an actual site with a ScriptAlias and
10215 a Redirect declared for the *exact same directory*. Even *my*
10216 compatibility fetish wouldn't motivate me to fix this if the fix
10217 required any effort, but it doesn't, so what the hey.
10219 *) Fixed to properly default several server_rec fields for virtual
10220 servers from the corresponding fields in the main server_rec.
10221 [Cliff Skolnick --- 'port' was a particular irritant].
10223 *) No longer kills off nph- child processes before they are
10224 finished sending output. [Matthew Gray]
10226 Changes with Shambhala 0.6.0 10 Jul 1995
10228 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10229 the connection to the client in an "aborted" state, but otherwise
10230 allow whatever handlers are running to clean up. hard_timeout()s
10231 abort the request in progress completely; anything not tied to some
10232 resource pool cleanup will leak. They're still around because I
10233 haven't yet come up with a more elegant way of handling
10234 timeouts when talking to something that isn't the client. The
10235 default_handler and the dir_handler now use soft timeouts, largely
10236 so I can test the feature. [Robert Thau]
10238 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10239 the case of log handlers dying prematurely is probably handled VERY
10240 gracelessly at this point, and if the logger stops reading input,
10241 the server will hang. (It is known to correctly restart the
10242 logging process on server restart; this is (should be!) going through
10243 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10244 script). [Robert Thau]
10246 *) asis files supported (new module). [Robert Thau]
10248 *) IdentityCheck code is compiled in, but has not been tested. (I
10249 don't know anyone who runs identd). [Robert Thau]
10251 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10252 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10254 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10256 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10257 as timeouts are not in scope. [Robert Thau]
10259 *) quoted-string args in config files now handled correctly (doesn't drop
10260 the last character). [Robert Thau; reported by Randy Terbush]
10262 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10263 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10265 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10266 default default type); the former default default behavior when all
10267 type-checkers defaulted had been a core dump. [Paul Sutton]
10269 *) Copy filenames out of the struct dirent when indexing
10270 directories. (On Linux, readdir() returns a pointer to the same
10271 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10273 Changes with Shambhala 0.5.3 [not released]
10275 *) Default response handler notes "file not found" in the error log,
10276 if the file was not found. [Cliff Skolnick].
10278 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10279 code no longer sets up bogus PATH_INFO which fakes out the directory
10280 handler). [Cliff Skolnick]
10282 Changes with Shambhala 0.5.2 06 Jul 1995
10284 *) Changes to http_main.c --- root server no longer plays silly
10285 games with SIGCHLD, and so now detects and replaces dying
10286 children. Child processes just die on SIGTERM, without taking
10287 the whole process group with them. Potential problem --- if any
10288 child process refuses to die, we hang in restart.
10289 MaxRequestsPerChild may still not work, but it certainly works
10290 better than it did before this! [Robert Thau]
10292 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10293 work (or work better, at least); over-long description lines
10294 properly terminated. [Mark Cox]
10296 *) http_request.c now calls unescape_url() more places where it
10297 should [Paul Sutton].
10299 *) More directory handling bugs (reported by Cox)
10300 Parent Directory link is now set correctly. [Robert Thau]
10302 Changes with Shambhala 0.5.1 04 Jul 1995
10304 *) Generalized cleanup interface in alloc.c --- any function can be
10305 registered with alloc.c as a cleanup for a resource pool;
10306 tracking of files and file descriptors has been reimplemented in
10307 terms of this interface, so I can give it some sort of a test.
10310 *) More changes in alloc.c --- new cleanup_for_exec() function,
10311 which tracks down and closes all file descriptors which have been
10312 registered with the alloc.c machinery before the server exec()s a
10313 child process for CGI or <!--#exec-->. CGI children now get
10314 started with exactly three file descriptors open. Hopefully,
10315 this cures the problem Rob H. was having with overly persistent
10316 CGI connections. [Robert Thau]
10318 *) Mutual exclusion around the accept() in child_main() --- this is
10319 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10320 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10321 This uses fcntl(F_SETLK,...) on the error log descriptor because
10322 flock() on that descriptor won't work on systems which have BSD
10323 flock() semantics, including (I think) Linux 1.3 and Solaris.
10325 This does work on SunOS (when the server is idle, only one
10326 process in the pool is waiting on accept()); it *ought* to work
10327 on the other systems. [Robert Thau]
10329 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10331 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10333 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10335 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10336 be unnecessary if I go to the revised timeout-handling scheme).
10339 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10340 string) even if none came in with the request. [Robert Thau]
10342 *) CHANGES file added to distribution ;-).
10344 Changes with Shambhala 0.4.5
10346 *) mod_dld --- early dynamic loading support [rst]
10347 *) Add wildcard content handlers for XBITHACK; default_hander now
10348 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10349 *) XBITHACK supported as a wildcard content-handler, and
10350 configurable at run-time (not just at compile time, as in the
10351 "patchy server" releases) [rst]
10353 Changes with Shambhala 0.4.4 30 Jun 1995
10355 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10356 *) Handle Addtype x/y .z [rst, reported by Cox]
10358 Changes with Shambhala 0.4.3
10360 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10361 synonymous [rst, terbush]
10363 Changes with Shambhala 0.4.1 28 Jun 1995
10365 *) First-cut virtual host implementation; some refit in the config
10366 reading code, and log management, was necessary to support this [rst]
10367 *) Sub-pool machinery, originally added to avoid excessive storage
10368 allocation on listings of large directories (which turned out to
10369 be the problem that the 0.3 storage accounting was added to
10370 find). Subrequests and mod_dir changed to use subpools. [rst]
10371 *) More memory debugging --- free list consistency checks. [rst]
10372 *) Added err_headers to request_rec, with support elsewhere [rst]
10373 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10375 Changes with Shambhala 0.3 19 Jun 1995
10377 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10378 *) Don't compile in mod_ai_backcompat by default
10379 *) Switch name of server from Apache to Shambhala in Makefile
10380 *) Add some accounting routines to track memory usage in the pools,
10383 Changes with Shambhala 0.2
10385 *) Set DOCUMENT_ROOT CGI variable
10386 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10387 *) Add critical section protection to handling of cleanup structures
10389 *) Significant code reorg within the server core to group related
10390 functions together [rst]
10391 *) Correctly handle clients that hang up before sending any request
10393 *) Replace dying child processes. [rst]
10395 Changes with Shambhala 0.1 12 Jun 1995
10397 Major rewrite of the pre-existing "patchy server" codebase, by
10398 Robert Thau (rst). Significant portions of the server code, such
10399 as configuration-file handling and HTTP authentication support,
10400 were ripped out and rewritten from scratch. Code that was not
10401 completely rewritten was significantly altered.
10403 Major changes with this release include:
10405 *) Introduction of the module API; in request handling, the central
10406 machinery just dispatches to various modules, which actually do
10407 most of the work. Configuration handling is similar --- modules
10408 declare their own commands, and the central machinery just
10409 dispatches to them.
10411 API features from shambhala/0.1 were substantially unchanged in
10412 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10413 release, such as wildcard handlers and subpools, were added in
10414 subsequent Shambhala releases, and were also generally rst's
10417 *) This release included the following modules:
10419 mod_access (access control --- allow and deny directives),
10420 mod_alias (Alias and Redirect commands),
10421 mod_auth (straight HTTP authentication, based on flat-files)
10422 mod_auth_dbm (same, with dbm files)
10423 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10424 mod_common_log (CLF access logs; later renamed mod_log_common)
10425 mod_dir (directory indexing)
10426 mod_include (server-side includes)
10427 mod_mime (AddType directives)
10428 mod_negotiation (content negotiation)
10429 mod_userdir (support for users' public_html directories)
10431 It also included a mod_ai_backcompat, which was a private hack
10432 for back-compatibility with rst's own AI-lab servers.
10434 All of these modules were substantially complete, and functional
10435 or nearly so (a few, which implemented features not in use at
10436 Thau's site, required patches of a few lines).
10438 *) sub-request machinery, to allow modules to determine how other
10439 modules would assign MIME types to a given file, or optionally
10440 serve its content (this is heavily used by mod_dir, mod_include
10441 and mod_negotiation).
10443 *) Resource pool system for keeping track of memory allocated and
10444 files opened in service of a particular request. Much of the
10445 code in the modules (when they weren't rewrites) was adjusted to
10446 replace a pervasive convention of using fixed-size buffers on
10447 the stack with an equally pervasive convention of using memory
10448 allocated with palloc().
10450 *) Reorganization of data structures associated with a given
10451 request to eliminate use of global variables and the troublesome
10452 unmunge_name function (used in NCSA and early Apache releases to
10453 attempt to determine the URI which mapped to a given filename
10454 --- a difficult proposition, given that it is easy to produce
10455 setups in which multiple URIs map to the same file).
10457 *) Source files renamed and rearranged
10459 *) Very simple pre-forking behavior --- parent process forked off a
10460 fixed number of children, and then just waited for SIGHUP.
10462 *) Other more minor changes too numerous to list.
10464 This release included modified versions of a lot of code from the
10465 Apache 0.6.4 public release, plus an early pre-forking patch
10466 codeveloped by Robert Thau and Rob Hartill.
10468 Changes with Apache 0.7.3 20 Jun 1995
10470 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10471 were incorporated by Rob Hartill on the main branch while Robert Thau
10472 worked on the Shambhala rewrite above. Most were merged into the
10473 Shambala architecture after Apache 0.8.0.
10475 Changes with Apache 0.6.4 13 May 1995
10477 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10480 Changes with Apache 0.5.1 10 Apr 1995
10482 Changes with Apache 0.4 02 Apr 1995
10484 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10487 Changes with Apache 0.3 24 Mar 1995
10489 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10492 Changes with Apache 0.2 18 Mar 1995
10494 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10495 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10496 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
