1 Changes with Apache 2.0.28-dev
3 *) Introduce an Apache mod_ssl initial configuration template
4 (ssl.conf, generated from ssl-std.conf). [Ralf S. Engelschall]
6 Changes with Apache 2.0.27
8 *) Fixed a memory leak in the getline parsing code that could
9 be triggered by arbitrarily large header lines. Requests
10 from the core input filter for single lines are now limited
11 to HUGE_STRING_LEN (8192 bytes). [Aaron Bannert]
13 *) Fix a truncation bug in how we print the port on the Via: header.
14 The routine that prints the Via: header now takes a length for
15 the port string. [Zvi Har'El <rl@math.technion.ac.il>]
17 *) Some syntax errors in mod_mime_magic's magic file can result
18 in a 500 error, which previously was unlogged. Now we log the
21 *) Add the support/checkgid helper app, which checks the run-time
22 validity of group identifiers usable in the Group directive.
25 *) Various --enable-so options have been fixed: --enable-so is
26 treated as "static"; explicit --enable-so=shared issues an error;
27 and explicit --enable-so fails with error on systems without
28 APR_HAS_DSO. [Aaron Bannert]
30 *) Fix a segfault in the core input filter when the client socket
31 gets disconnected unexpectedly. [Cliff Woolley]
33 *) Fix the reporting for child processes that die. This removes
34 all of the non-portable W* macros from Apache.
35 [Jeff Trawick and Ryan Bloom]
37 *) Win32: Track and display "Parent Server Generation:" in
38 mod_status output. The generation will be bumped at
39 server graceful restart, when the child process exits
40 by hitting MaxRequestsPerChild or if the child
41 process exits abnormally. [Bill Stoddard]
43 *) Win32: Fix problem where MaxRequestsPerChild directive was
44 not being picked up in favor of the default. Enable
45 the parent to start up a new child process immediately upon
46 the old child starting shutdown.
49 *) Fix some bungling of the remote port in rfc1413.c so that
50 IdentityCheck retrieves the proper user id instead of failing
51 and thus always returning "nobody."
52 [Dick Streefland <Dick.Streefland@xs4all.nl>]
54 *) Introduced thread saftey for mod_rewrite's internal cache.
55 [Brian Pane <bpane@pacbell.net>]
57 *) Simplified mod_env's directives to behave as most directives are
58 expected, in that UnsetEnv will not unset a SetEnv and PassEnv
59 directive following that UnsetEnv within the same container.
60 Also provides a runtime startup warning if a PassEnv configured
61 environment value is undefined. [William Rowe]
63 *) The worker MPM is now completely ported to APR's new lock API. It
64 uses native APR types for thread mutexes, cross-process mutexes,
65 and condition variables. [Aaron Bannert]
67 *) Sync up documentation to remove all references to the now deprecated
68 Port directive. [Justin Erenkrantz]
70 *) Moved all ldap modules from the core to httpd-ldap sub-project
73 *) Exit when we can't listen on any of the configured ports. This
74 is the same behavior as 1.3, and it avoids having the MPMs to
75 deal with bogus ap_listen_rec structures. [Jeff Trawick]
77 *) Cleanup the proxy code that creates a request to the origin
78 server. This change adds an optional hook, which allows modules
79 to gain control while the request is created if the proxy module
80 is loaded. The purpose of this hook is to allow modules to add
81 input and/or output filters to the request to the origin. While
82 I was at it, I made the core use this hook, so that proxy request
83 creation uses some of the code from the core. This can still be
84 greatly improved, but this is a good start. [Ryan Bloom]
86 Changes with Apache 2.0.26
88 *) Port the MaxClients changes from the worker MPM to the threaded
91 *) Fix mod_proxy so that it handles chunked transfer-encoding and works
92 with the new input filtering system. [Justin Erenkrantz]
94 *) Introduce the MultiviewsMatch directive, to allow the operator
95 to be flexible in recognizing Handlers and Filters filename
96 extensions as part of the Multiviews matching logic, strict with
97 MultiviewsMatch NegotiatedOnly to accept only filename extentions
98 that designate negotiated parameters, (content type, charset, etc.)
99 or MultiviewsAll for the 1.3 behavior of matching any files, even
100 if they have unregistered extensions. [William Rowe]
102 *) Fixed the configure script to add a LoadModule directive to
103 the default httpd.conf for any module that was compiled
104 as a DSO. [Aaron Bannert <aaron@clove.org>]
106 *) rewrite mod_ssl input filtering to work with the new input filtering
107 system. [Justin Erenkrantz]
109 *) prefork: Don't segfault when we are able to listen on some but
110 not all of the configured ports. [Jeff Trawick]
112 *) Build mod_so even if no core modules are built shared.
113 [Aaron Bannert <aaron@clove.org>]
115 *) Introduce ap_directory_walk rewrite (with further optimizations
116 required) to adapt to the ap_process_request_internal() changes.
117 Optimized so subrequests and redirects now reuse previous section
118 merges, until we mismatch with the original directory_walk, and
119 precomputed r->finfo results will cause directory_walk to skip
120 the most expensive phases of the function. [William Rowe]
122 *) Allow ApacheMonitor to connect to and control Apache on other
123 WinNT/2K machines. [Mladen Turk <mturk@mappingsoft.com>]
125 *) Remove the Port directive. In it's place, the Listen directive
126 is now a required directive, which tells Apache what port to
127 listen on. The ServerName directive has also been extended
128 to accept an optional port. If the port is specified to the
129 ServerName, the server will report that port whenever it
130 reports the port that it is listening on. This change was
131 made to ease configuration errors that stem from having a Port
132 directive, and a Listen directive. In that situation, the server
133 would only listen to the port specified by the Listen command,
134 which caused a lot of confusion to users. [Ryan Bloom]
136 *) Added mod_mime_magic, mod_unique_id and mod_vhost_alias to the Win32
137 build, as loadable modules. [William Rowe]
139 *) Fix --enable-mods-shared processing. If most is specified,
140 then all modules that can be compiled as shared modules are.
141 [Aaron Bannert <aaron@clove.org>]
143 *) Update the mime.types file to map video/vnd.mpegurl to mxu
144 and add commonly used audio/x-mpegurl for m3u extensions.
145 [Heiko Recktenwald <uzs106@uni-bonn.de>, Lars Eilebrecht]
147 *) Eliminate the depreciated r->content_language, in favor of the array
148 r->content_languages introduced many years ago. Module authors must
149 substantially overhaul their modules, so this needs to be upgraded
150 if the module still relied on backwards-brokeness. [William Rowe]
152 *) Allow configure help strings to work with autoconf 2.50+ and 2.13.
155 *) Rewrite the input filtering mechanisms to consolidate and reorganize
156 code. In short, core_input_filter does something now and
157 ap_http_filter is now only concerned with HTTP. [Justin Erenkrantz]
159 *) Update the Win32 build to re-absorb mod_proxy and family.
162 *) Resolved the build failure on Win32 using MSVC 5.0 (without the
163 current SDK.) [William Rowe]
165 *) Some style changes to the code that does ProxyErrorOverride. Fixed
166 config merge behaviour. [Graham Leggett]
168 *) Allow support programs to be compiled against a static version
169 of libapr. This allows the smaller support programs to be
170 relocated. [Aaron Bannert <aaron@clove.org>]
172 *) Update the mime.types file to the registered media types as
173 of 2001-09-25, and add mapping for xsl extension [Mark Cox]
175 *) Fix MaxClients in the Worker MPM, so that it specifies the maximum
176 number of clients that can connect at the same time, instead of
177 specifying the maximum number of child processes.
178 [Aaron Bannert <aaron@clove.org>]
180 *) Switch proc_pthread AcceptMutex configuration directive to pthread to
181 be consistent with 1.3. [Justin Erenkrantz]
183 *) Cache apr_explode_localtime() value for 15 seconds.
184 [Brian Pane <bpane@pacbell.net>]
186 *) Fix mod_include to not return ETag or Last-Modified headers.
187 [Ian Holsman <ianh@cnet.com>]
189 *) Fix worker MPM's scoreboard logic. [Aaron Bannert <aaron@clove.org>]
191 *) Eliminate the wasteful run-time conversion of method names from strings
192 to numbers in places where the methods are known at compile time.
193 [Brian Pane <bpane@pacbell.net>]
195 *) Turn the worker MPM's queue into a LIFO. This may
196 improve cache-hit performance under some conditions.
197 [Aaron Bannert <aaron@clove.org>]
199 *) Switch back to SIGUSR1 for graceful restarts on all platforms that
200 support it. [Justin Erenkrantz]
202 *) Cleanup the worker MPM. We no longer re-use transaction
203 pools. This incurs less overhead than shuffling the pools
204 around so that they can be re-used. Remove one of the
205 queue's condition variables. We just redefined the API to
206 state that you can't try to add more stuff than you allocated
207 segments for. [Aaron Bannert <aaron@clove.org>]
209 *) Fix SSL VPATH builds [Cody Sherr <csherr@covalent.net>]
211 *) Fixed persistent connections when a request contains a body.
214 *) mod_dav uses a new API to speak to the backend provider for dead
215 property management. [Greg Stein]
217 *) Remove the Win32 script-processing exception from mod_cgi, and
218 roll build_command_line/build_argv_list into a unified, overrideable
219 ap_cgi_build_command optional function. [William Rowe]
221 *) Rewrite find_start_sequence to use a better search algorithm
222 to find the start tag. [Justin Erenkrantz]
224 *) Fix a seg fault in mod_include. When we are generating an
225 internal redirect, we must set r->uri to "", not a bogus
226 string, and not NULL. [Ryan Bloom]
228 *) Optimized location_walk, so subrequests, redirects and second passes
229 now reuse previous section merges on a <Location > by <Location >
230 basis, until we mismatch with the original location_walk.
233 *) Back out the 1.45 change to util_script.c. This change made
234 us set the environment variable REQUEST_URI to the redirected
235 URI, instead of the originally requested URI.
236 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
238 *) Make mod_include do lazy evaluation of potentially expensive to
239 compute variables. [Brian Pane <bpane@pacbell.net>]
241 *) Fix logging of bytes sent for HEAD requests. %b and %B should
242 log either - or 0, before this patch, they were both logging
243 the file size. [Taketo Kabe <kabe@sra-tohoku.co.jp>]
245 *) Make mod_include check for BYTE_CHECK_THRESHOLD per bucket rather
246 than per character. [Brian Pane <bpane@pacbell.net>]
248 *) Normalize the primary request, redirects and sub-requests to
249 run the same ap_process_request_internal for consistency in
250 robustness, behavior and security. [William Rowe]
252 *) Fix a segfault with mod_include when r->path_info is not set
253 (which is the case with mod_proxy). [Ian Holsman <ianh@cnet.com>]
255 *) Add -X functionality back. This indicates to all MPMs and any other
256 part of Apache that it should run in "debug" mode. [Justin Erenkrantz]
258 *) Some initial support for the cygwin platform [prefork only].
259 This is not to be confused with support for the WinNT/Win32
260 platform, which is the recommended configuration for native
261 Win32 users. The cygwin platform support is recommended for
262 cygwin platform users. [Stipe Tolj <tolj@wapme-systems.de>]
264 *) Changed syntax of Set{Input|Output}Filter. The list of filters
265 must be semicolon delimited (if more than one filter is given.)
266 The Set{Input|Output}Filter directive now overrides a parent
267 container's directive (e.g. SetInputFilter in <Directory /web/foo>
268 will override any SetInputFilter directive in <Directory /web>.)
269 This new syntax is more consistent with Add{Input|Output}Filter
270 directives defined in mod_mime. Also cures a bug in prior releases
271 where the Set{Input|Output}Filter directive would corrupt the
272 global configuration if the multiple directives were nested.
275 *) Cured what's ailed mime for quite some time. If an AddSomething
276 was given in the configuration (Language, Charset, Handler or
277 Encoding) Apache would set the content type as given by AddType,
278 but refused to check the mime.types file if AddType wasn't given
279 for that specific extension. Setting the AddHandler for .html
280 without setting the AddType text/html html would cause Apache to
281 use the default content type. [William Rowe]
283 *) Added some bulletproofing to memory allocation in the LDAP cache
284 code. [Graham Leggett]
286 Changes with Apache 2.0.25
288 *) Move the installed /manual directory out of the /htdocs/ tree, so
289 that it can be kept more independently from the remaining document
290 root. The "Alias /manual ..." already allowed for easy projection
291 into existing private document trees. [Martin Kraemer]
293 *) Add specified user attributes to the environment when using
294 mod_auth_ldap. This allows you to use mod_include to embed specified
295 user attributes in a page like so:
296 Hello <!--#echo var="AUTHENTICATE_CN"-->, how are you?
299 *) Fix a performance problem with the worker MPM. We now create
300 transaction pools once, and re-use them for each connection.
301 [Aaron Bannert <aaron@clove.org>]
303 *) Modfied mod_mime to prevent mod_negotation from serving a multiview
304 of a 'handler' or 'filter', so that any filename extension that does
305 not contribute to the negotiated metadata can't be served without
306 an explicit request. E.g., if the .Z extension is associated with
307 an unzip filter, the user request somefile.Z.html, mod_negotiation
308 won't serve it. It can serve somefile.Z.html when somefile.Z is
309 requested, since the .Z extension is explictly requested, if the
310 .html extension is associated with ContentType text/html.
313 *) Introduce the AddInputFilter filter[;filter...] ext [ext...]
314 and corresponding AddOutputFilter syntax, to insert one or more
315 filters by mod_mime filename extension processing.
318 *) Fix a growing connection pool in core_output_filter() for
319 keepalive requests. [Jeff Trawick]
321 *) Moved split_and_pass_pretag_buckets back to being a
322 macro at Ryans's request. Removed the return from it
323 by setting and returning a return code instead. Updated
324 the code to check the return code from the macro and
325 do the right thing. [Paul J. Reder]
327 *) Fix a segfault when a numeric value was received for Host:.
330 *) Add a function ap_remove_input_filter. This is to match
331 up with ap_remove_output_filter. [Ryan Bloom]
333 *) Clean up location_walk, so that this step performs a minimum
334 amount of redundant effort (it must be run twice, but it will no
335 longer reparse all <Location > blocks when the request uri
336 hadn't changed.) [William Rowe]
338 *) Eliminate proxy: (and all other 'special') processing from the
339 ap_directory_walk() phase. Modules that want to use special
340 walk logic should refer to the mod_proxy map_to_location example,
341 with it's proxy_walk and proxysection implementation. This makes
342 either directory_walk flavor much more legible, since that phase
343 only runs against real <Directory > blocks.
346 *) Fix a security problem in mod_include which would allow
347 an SSI document to be passed to the client unparsed.
348 [Cliff Woolley, Brian Pane]
350 *) Introduce the map_to_storage hook, which allows modules to bypass
351 the directory_walk and file_walk for non-file requests. TRACE
352 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
353 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
356 *) Add the ability for mod_include to add the INCLUDES filter
357 if the file is configured for the server-parsed handler.
358 This makes the configuration for .shtml files much easier
359 to understand, and allows mod_include to honor Apache 1.3
360 config files. Based on Doug MacEachern's patch to PHP
361 to do the same thing. [Ryan Bloom]
363 *) force OpenSSL to ignore process local-caching and to always
364 get/set/delete sessions using mod_ssl's callbacks
365 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
366 Geoff Thorpe <geoff@geoffthorpe.net>]
368 *) Make the worker MPM shutdown and restart cleanly. This also
369 cleans up some race conditions, and gets the worker using
370 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
372 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
374 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
376 *) Fix for mod_include. Ryan's patch to check error
377 codes put a return in the wrong place. Also, the
378 include handler return code wasn't being checked.
379 I don't like macros with returns, so I converted
380 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
381 [Paul J. Reder <rederpj@raleigh.ibm.com>]
383 *) fix segv in mod_mime if no AddTypes are configured
384 [John Sterling <sterling@covalent.net>]
386 *) Enable ssl client authentication at SSL_accept time
387 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
389 *) Fix a segfault in mod_include when the original request has no
390 associated filename (e.g., we're filtering the error document for
391 a bad URI). [Jeff Trawick]
393 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
395 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
396 of httpd is started and shuts down due to socket conflict. Moving the
397 call to ap_log_pid solves the problem.
399 *) Changed the late-1.3 log_config substitution %c to %X, to log the
400 status of the closed connection, as it conflicts with the far more
401 common, historical ssl logging directive %...{var}c. [William Rowe]
403 *) Added the common error/ tree to the build/install targets
404 (similar to the common icons/ tree) for the multi-language error
405 messages that Lars committed earlier. [William Rowe]
407 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
409 *) Added a default commented-out mod_ldap and mod_auth_ldap
410 configuration to httpd-std.conf and httpd-win.conf
413 *) Added documentation for mod_ldap and mod_auth_ldap.
416 *) Enabled negative caching on attribute comparisons in the LDAP cache.
417 Fixed a problem where the default cache TTL was set in milliseconds
418 not microseconds causing the cache to time out almost immediately.
421 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
422 module code to follow APR. [Graham Leggett]
424 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
425 cleaned up when the connection pool pool is cleaned up.
428 *) Fix a minor issue with Jeff Trawick's mod_include
429 patch. Without this patch, the code will just allocate
430 more bytes in get_combined_directive than are needed.
433 *) Added the LDAP authentication module mod_auth_ldap.
434 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
436 *) Added the LDAP cache and connection pooling module mod_ldap.
437 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
439 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
440 by allowing a module to disable itself if its prerequisites are not
441 met. [Justin Erenkrantz]
443 Changes with Apache 2.0.24
445 *) Fix a couple of issues in mod_include when the tag appeared at
446 offsets near 8192 in the file being parsed. [Jeff Trawick]
448 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
449 reached. [Jeff Trawick]
451 *) Numerous improvements to the Win32 build system. Introduced command line
452 builds without requiring .mak files for MSVC 6.0 and later versions.
453 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
456 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
457 reporting of uninstalled services and other error conditions, and changed the
458 default service name to Apache2. [William Rowe]
460 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
461 compatibility with existing Apache 1.3 Win32 Apache management utilites.
462 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
464 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
465 [William Rowe, Greg Ames]
467 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
468 and RemoveCharset directives. [William Rowe]
470 *) The Unix MPMs other than perchild now allow child server
471 processes to use the accept mutex when starting as root and
472 using SysV sems for the accept mutex. Previously, this
473 combination would lead to fatal errors in the child server
474 processes. perchild can't use SysV sems because of security
475 issues. [Jeff Trawick, Greg Ames]
477 *) Added Win32 revision stamp resources to all http binaries
478 (including modules/ and support/ tools.) PR7322 [William Rowe]
480 *) Fix ap_rvprintf to support more than 4K of data at one time.
481 [Cody Sherr <csherr@covalent.net>]
483 *) We have always used the obsolete/deprecated Netscape syntax
484 for our tracking cookies; now the CookieStyle directive
485 allows the Webmaster to choose the Netscape, RFC2109, or
486 RFC2965 format. The new CookieDomain directive allows the
487 setting of the cookie's Domain= attribute, too. PR #s 5006,
488 5023, 5920, 6140 [Ken Coar]
490 *) Tweak server/Makefile so that the rules for generating exports.c
491 are compatible with make utilities which don't expand wildcards
492 in a dependency list (e.g., OS/390 make, certain levels of GNU
493 make). [Jeff Trawick]
495 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
497 *) Begin to sanitize the MPM configuration directives. Now, all
498 MPMs use the same functions for all common MPM directives. This
499 should make it easier to catch all bugs in these directives once.
500 [Cody Sherr <csherr@covalent.net>]
502 *) Close a major resource leak. Every time we had issued a
503 graceful restart, we leaked a socket descriptor.
506 *) Fix a problem with the new method code. We need to cast
507 the 1 to an apr_int64_t or it will be treated as a 32-bit
508 integer, and it will wrap after being shifted 32 times.
509 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
511 *) Fix a bug in mod_expires. Previous to this patch, if you
512 told mod_expires to add 604800 seconds to the last-modified
513 time, it actually added 604800 usec's to the last-modified time,
514 so that when looking at the response it looked like nothing
515 had been done. The root of the problem was that we always compute
516 time in usec's, but we ask users to input sec's. This means we
517 need to convert to usec's before using those values.
520 *) The worker MPM now handles shutdown and restart requests. It
521 definitely isn't perfect, but we do stop the servers correctly.
522 The biggest problem right now is that SIGHUP causes the server to
523 just die. [Ryan Bloom]
525 Changes with Apache 2.0.23
527 *) Use the prefork MPM by default on Unix. [various]
529 *) Added a systray icon monitor application for Win32.
530 [Mladen Turk <mturk@mappingsoft.com>]
532 *) mod_rewrite: Fix the line ending on some non-Unix systems for
533 messages written to the rewrite log.
534 [Richard Labennett <rlabenn@us.ibm.com>]
536 *) All mod_autoindex query parsing is now quietly quashed with the
537 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
538 still drops the column sort <a href>'s for the column headers, but
539 IgnoreClient is required to ignore these Query options entirely.
542 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
543 to allow the client to select plain, FancyIndexing or HTMLTable
544 formatting, V=[0|1] to inhibit or enable version sorting, and
545 P=pattern to return only specific files. The old Query Arguments
546 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
547 as before), and O=A|D for ordering ascending or descending.
550 *) Fixed an error in mod_include's directive parsing routines which
551 caused #if, #elif, and #else expressions containing backslashes
552 to be improperly evaluated. [Cliff Woolley]
554 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
555 drop the icon column, SuppressRules to drop the <hr> elements,
556 and HTMLTable to create rudimentary HTML table listings (implies
557 FancyIndexing). [William Rowe]
559 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
560 from Apache 1.3.15. This is needed for two reasons, first, given
561 multiple machines within a server farm, ETags and Last-Modified
562 stamps won't correspond from machine to machine, and second, many
563 Unixes don't capture changes to the date or time stamp of existing
564 files, since these don't modify the dirent itself. [William Rowe]
566 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
567 and DirectoryWidth options from Apache 1.3.10.
568 [William Rowe, Ken Coar]
570 *) Eliminated FancyIndexing directive, deprecated early in Apache
571 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
573 *) mod_autoindex now excludes any file names that would result in
574 an error, other than a success or redirect. Also optimized
575 the parent directory, always included except in the URI '/'.
578 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
579 negotiated index pages, and prevent the server from defaulting
580 to an autoindex of the directory. mod_negotiation will now die
581 with a 500 Internal Error if it could match some filenames
582 (e.g. for mod_dir) but none can be served. mod_negotation now
583 refuses to serve any file with an extention that mod_mime doesn't
584 recognize, and wasn't part of the request. [William Rowe]
586 *) Eliminate mod_cgi's handling of .exe files without the .exe file
587 extension. This is already handled by multiviews, if the admin
588 wishes to AddHandler .exe or define a content type handler and
589 associate .exe files with that content type. Multiviews must be
590 enabled to allow these to be served. [William Rowe]
592 *) Speed up the server's response to a spike in incoming workload
593 or restarts by assigning empty scoreboard slots to new processes
594 when they are available. [Greg Ames]
596 *) Add a handler to mod_includes.c. This handler is designed to
597 implement the XbitHack directive. This can't be done with a
598 fixup, because we need to check the content-type, which is
599 only available in the handler phase. [Ryan Bloom]
601 *) Make the includes filter check return codes from filters lower in
602 the filter chain. If a lower level filter returns an error, then
603 the request needs to stop immediately. This allows mod_include to
604 stop parsing data once a lower filter recognizes an error.
607 *) Add the ability to extend the methods that Apache understands
608 and have those methods <limit>able in the httpd.conf. It uses
609 the same bit mask/shifted offset as the original HTTP methods
610 such as M_GET or M_POST, but expands the total bits from an int to
611 an ap_int64_t to handle more bits for new request methods than
612 an int provides. [Cody Sherr <csherr@covalent.net>]
614 *) Fix broken mod_mime behavior in merging its arguments. Possible
615 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
617 *) Solve many mod_ssl porting issues (too many to detail) with
618 help from the whole team, but most notably [Ralf S. Engelschall,
619 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
620 Doug MacEachern, William Rowe, Cliff Woolley]
622 *) More stall fixes for the threaded & worker mpm's.
623 Make mod_status output more accurate. Don't
624 count workers in processes which aren't actively
625 serving requests. [Greg Ames]
627 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
629 *) Add a single listener/multiple worker MPM. This MPM is
630 definately not fully correct, but it allows us to solve many
631 of the problems that exist in the threaded MPM. This is a
632 modified version of the threaded MPM. [Ryan Bloom]
634 *) Improve content generation throughout Apache, providing closer
635 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
636 Transitional specifications. [William Rowe]
638 Changes with Apache 2.0.22
640 *) Fix a problem where the threaded MPM stalls after restarts or
641 segfaults. Also prevent multiple active processes from using
642 the same scoreboard slot. [Greg Ames]
644 *) Apache/Win32 now fills in the service description with Apache's
645 server version string, including loaded and advertised modules.
648 *) Improved support for the Win32 build, to recover gracefully from
649 missing apr or apr-util directories or the awk interpreter,
650 create the proper cgi-bin examples, including a test-cgi.bat, and
651 fix the perl shebang line for printenv.pl, when installing from
652 the build environment. [William Rowe]
654 *) Fix a segfault in threaded.c caused by passing uninitialized
655 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
657 *) Use new APR number conversion functions to reduce CPU consumption
658 when setting the content length, and in mod_log_config.
661 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
662 where HEAD response headers were being repeated twice for
663 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
664 problem in the http_header filter was exposed by the recent rewrite
665 of the content_length filter. [Taketo Kabe, Bill Stoddard]
667 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
668 restarts. A garbage pointer to a vhost's server_rec from the
669 previous generation was being left around under certain
670 conditions. [Greg Ames]
672 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
673 used to appear as '(none', without the closing paren.
674 [Günter Knauf <eflash@gmx.net>]
676 *) Improve the exports generating awk script. In the past, we had
677 work around problems in the awk script by avoiding some #if and
678 #ifdefs. This has bitten us many times in generating the exports.c
679 file. This improvement allows corrects the header file parsing.
680 [Sander Striker <striker@apache.org>]
682 Changes with Apache 2.0.21
684 *) Resolve the Win32 htpasswd bug, where a file that existed would be
685 overwritten, regardless of the -c flag.
686 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
688 *) Introduce connection sub-pools into ab. Truncating the lifetime
689 of these allocations means that ab no longer perpetually grows
690 its working set, running out of memory on large request attempts.
693 *) Make scoreboard creation a hook. This allows management
694 modules to have access to the scoreboard at the time that it is
695 created, and at every restart request.
696 [Cody Sherr <csherr@covalent.net>]
698 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
699 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
700 daemon index actually used in the scoreboard. I also
701 updated the pertinent calls. [Paul J. Reder]
703 *) Win32: Prevent listening sockets from being inherited by
704 the Apache child process, CGI scripts, rotatelog process
705 etc. If the Apache child process segfaults, any processes
706 that the child started are not reaped. Prior to this fix,
707 these processes inherited the listening sockets which sometimes
708 prevented the restarted Apache child process from accepting
709 connections (ie, the server would hang).
712 *) Provide vhost and request strings when ExtendedStatus is on.
715 *) Fix some issues with the pod and prefork: check the pod *after*
716 processing a connection so that a server processing a time-
717 consuming request bails out as soon as practical; when the
718 parent process wakes up a server process via connect(), use an
719 APR timeout on the connect() so that we don't hang for a long
720 time if there aren't server processes around to do accept().
721 [Jeff Trawick, Greg Ames]
723 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
724 spends a lot of time in apr_table_get calls. Using the default
725 httpd.conf, the tables for languages and charsets are somewhat
726 large, so the time spent scanning them on each request is
727 significant. Replacing the tables with hash tables provides
728 a nice speedup. [Brian Pane <bpane@pacbell.net>]
730 *) Add two functions to allow modules to access random parts of the
731 scoreboard. This allows modules compiled for one MPM to access the
732 scoreboard, even if it the server was compiled for another MPM.
733 [Harrie Hazewinkel <harrie@covalent.net>]
735 Changes with Apache 2.0.20
737 *) Fix problem in content-length filter where the filter would
738 buffer all the output from a CGI before sending any bytes
739 down the filter stack to the network. This problem would cause
740 significant memory consumption if the CGIs generated
741 lots of bytes. [Bill Stoddard]
743 *) Get non-blocking CGI pipe reads working with the bucket brigades.
746 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
749 *) Fix a bug in the threaded MPM that would cause it to kill off all
750 workers immediately after starting if the number of workers started
751 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
753 Changes with Apache 2.0.19
755 *) Fix problem with threaded MPM. The problem was that if each child
756 process was busy serving a single long-lived request and the server
757 was sent a graceful restart signal, the server would stop serving
758 requests. This would happen because each child process would wait to
759 die until the last thread was done, and the parent wouldn't spawn any
760 new children until a process died. Now, the parent looks at the fact
761 that the children are dying gracefully, and starts new children.
762 Those new children only start enough threads to compliment the number
763 of threads in the other child process that shares the same spot in
764 the scoreboard. In this way, we make sure to never go over
765 MaxClients. [Ryan Bloom]
767 *) modified mod_negotiation and mod_autoindex to speed up by almost a
768 factor of two on apr_dir_read()-enhanced platforms, such as Win32
769 and OS2, by calling ap_sub_request_lookup_dirent() with the results
770 already provided by apr_dir_read(). [William Rowe]
772 *) mod_file_cache is now more robust to filtering and serves requests
773 slightly more efficiently. [Cliff Woolley]
775 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
776 Module was calling ap_rwrite() followed by ap_rflush() but the
777 served content was not being displayed in the browser. Inspection
778 of the output stream revealed that the first data chunk was
779 missing the trailing CRLF required by the RFC. [Bill Stoddard]
781 *) apxs no longer generates ap_send_http_header() in the example handler
783 *) Fix an ab problem which could cause a divide-by-zero exception
784 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
785 [Ian Holsman <ianh@cnet.com>]
787 *) Solve case-insensitive platforms' confusion about negotiated
788 filenames, allowing files of differnt case to match in choosing
789 the document to serve. [William Rowe]
791 *) Fix brokenness when ThreadsPerChild is higher than the built-in
792 limit. We left ap_threads_per_child at the higher value which
793 led to segfaults when doing certain scoreboard operations.
796 *) Fix seg faults and/or missing output from mod_include. The
797 default_handler was using the subrequest pool for files and
798 MMAPs, even though the associated APR structures typically
799 live longer than the subrequest. [Greg Ames]
801 *) Extend mod_setenvif to support specifying regular expressions
802 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
803 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
804 will cause HAVE_TS to be set if any of the request headers begins
805 with "TS" and has a value that begins with any character in the
806 set [a-z]. [Bill Stoddard]
808 *) httpd children now re-bind themselves to a random CPU on
809 multiprocessor systems on AIX via bindprocessor() in 2.0.
810 [Victor J. Orlikowski]
812 *) Fix htdigest. It would go into a loop in getline when adding
813 a second user. [Bill Stoddard]
815 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
817 *) Automatically generate httpd.exp for AIX.
818 DSOs now work again on AIX in 2.0
819 [Victor J. Orlikowski]
821 *) Add a new request hook, error_log. This phase allows modules
822 to act on the error log string _after_ it has been written
823 to the error log. The goal for this hook is to allow monitoring
824 modules to send the error string to the monitoring agent.
827 *) Modify mod_echo to make it use filters for input and output.
828 [Ryan Morgan <rmorgan@covalent.net>]
830 *) Extend mod_headers to support conditional driven Header
831 add, append and set. Use SetEnvIf to set an envar and conditionally
832 add/append/set headers based on this envar thusly:
834 SetEnvIf TSMyHeader value HAVE_TSMyHeader
835 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
837 If the request contains header "TSMyHeader: value" then header
838 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
841 *) Extend mod_headers to support using format specifiers on Header
842 add, append and set header values. Two format specifiers are supported:
844 %t - reports, in UTC microseconds since the epoch, when the
845 request was received.
847 %D - reports the time, in microseconds, between when the request was
848 received and the response sent.
851 Header add MyHeader "This request served in %D microseconds. %t"
853 results in a header being added to the response that looks like this:
855 MyHeader: This request served in D=5438 microseconds. t=991424704447256
859 *) Fix reset_filter(). We need to be careful how we remove filters.
860 If we set r->output_filters to NULL, we also have to reset the
861 connection's filters. [John Sterling]
863 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
865 *) Add a check to ap_die() to make sure the filter stack is sane and
866 contains the correct basic filters when an error occurs. This fixes
867 a problem where headers are not being sent on error. [John Sterling]
869 *) New Header directive 'echo' option. "Header echo regex" will
870 cause any headers received on the request that match regex to be
871 echoed to (included in) the response headers.
874 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
875 This prevented the inclusion of apr_compat.h. PR #7773
876 [Oleg Broytmann <phd@phd.pp.ru>]
878 *) Moved util_uri to the apr-util library. This required a bunch of
879 apr_name changes for the uri utility functions. [Justin Erenkrantz]
881 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
882 insert_filter phase so that other filters are not bypassed by default.
885 *) Reimplement mod_headers as an output filter. mod_headers can now
886 add custom headers to inbound requests using the RequestHeader directive
887 and to responses using the same old Header directive. [Graham Leggett]
889 Changes with Apache 2.0.18
891 *) Fix command-line processing so that if a bad argument is specified
892 Apache will exit. [Jeff Trawick]
894 *) Change the make targets and rules to be consistent in all of the
895 Apache-owned source trees. [Roy Fielding]
897 *) Fix processing of the TRACE method. Previously we passed bogus
898 parms to form_header_field() and it overlaid some vhost structures,
899 resulting in a segfault in check_hostalias().
900 [Greg Ames, Jeff Trawick]
902 *) Win32: Add support for reliable piped logs. If the logging process
903 goes down, Apache will automatically restart it. This function has
904 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
907 *) Do not start piped log processes during the config file
908 preflight. This change also circumvents a problem on
909 Windows where the rotatelog processes created during preflight
910 was not getting cleaned up properly.
913 *) add "Request Phase Participation" info to mod_info
916 *) Make first phase changes to the scoreboard data structures in
917 preparation for the rewriting of the scoreboard per my posted
918 design notes. [Paul J. Reder]
920 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
921 and apr-util, allow it to be overridden by the configure command-line
922 (default="--silent") and introduce LT_LDFLAGS to replace what we were
923 formerly abusing as LTFLAGS. [Roy Fielding]
925 *) Clean up the reporting of incorrect closing container tags.
926 [Barrie Slaymaker <barries@slaysys.com>]
928 *) Simplify the configure process by moving all libtool stuff to APR
929 and moving hints.m4 inline. [Roy Fielding]
931 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
932 of functions used by mod_proxy for export in the DLL
933 [Ian Holsman <IanH@cnet.com>]
935 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
936 request body from its stdin but no reqest body is being written to
937 the cgi. [Jeff Trawick]
939 *) mod_log_config: %c connection status incorrectly logged
940 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
943 *) Get mod_cern_meta working under Windows
946 *) Create Files, and thus MMAPs, out of the request pool, not the
947 connection pool. This solves a small resource leak that had us
948 not closing files until a connection was closed. In order to do
949 this, at the end of the core_output_filter, we loop through the
950 brigade and convert any data we have into a single HEAP bucket
951 that we know will survive clearing the request_rec.
952 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
955 *) Completely revamp configure so that it preserves the standard make
956 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
957 the configure additions to EXTRA_* variables. Also, allow the user
958 to specify NOTEST_* values for all of the above, which eliminates the
959 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
960 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
961 avoid pointless duplications. Fix the order in which flags are given
962 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
963 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
964 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
965 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
967 *) Get mod_tls to compile/work better on Windows. PR #7612
968 [Bernhard Schrenk <b.schrenk@improx.com>]
970 *) Fix shutdown/restart hangs in the threaded MPM.
971 [Jeff Trawick, Greg Ames, Ryan Bloom]
973 *) Removed the keptalive boolean from conn_rec because it is now only
974 used by a single routine and can be replaced by a local variable.
975 [Greg Stein, Ryan Bloom, Roy Fielding]
977 *) Patch prefork to put enough of the signal processing back in so that
978 signals are all handled properly now. The previous patch fixed the
979 deadlock race condition, but broke the user directed signal handling.
980 This fixes it to work the way it did before my previous prefork patch
981 (primarily, SIGTERM is now working).
983 *) Change how input filters decide how much data is returned to the
984 higher filter. We used to use a field in the conn_rec, with this
985 change, we use an argument to ap_get_brigade to determine how much
986 data is retrieved. [Ryan Bloom]
988 *) Fix seg fault at start-up introduced by Ryan's change to enable
989 modules to specify their own logging tags. mod_log_config
990 registers an optional function, ap_register_log_handler().
991 ap_register_log_handler() was being called by http_core before
992 the directive hash table was created. This patch creates the
993 directive hash table before ap_register_log_handler() is
994 registered as an optional function.
995 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
997 *) Add ap_set_int_slot() function
998 [John K. Sterling <sterling@covalent.net>]
1000 *) Under certain circumstances, Apache did not supply the
1001 right response headers when requiring authentication.
1002 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
1003 (This is a port of the change that went into Apache 1.3.19.)
1005 *) Allow modules to specify their own logging tags. This basically
1006 allows a module to tell mod_log_config that when %x is encountered
1007 a specific function should be called. Currently, x can be any single
1008 character. It may be more useful to make this a string at some point.
1011 Changes with Apache 2.0.17
1013 *) If a higher-level filter handles the the byterange aspects of a
1014 request, then the byterange filter should not try to redo the
1015 work. The most common case of this happening, is a byterange
1016 request going through the proxy, and the origin server handles
1017 the byterange request. The proxy should ignore it.
1018 [Graham Leggett <minfrin@sharp.fm>]
1020 *) Changed the threaded mpm to have child_main join to each of the
1021 worker threads to make sure the kids are all gone before child_main
1022 exits after a signal (cleanup from perform_idle_server_maintenance).
1023 This is an extension of Ryans recent commit to make the child_main
1026 *) Add more options to the ap_mpm_query function. This also allows MPMs to
1027 report if their threads are dynamic or static. Finally, this also
1028 implements a new API, ap_show_mpm, which returns the MPM that was
1029 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
1031 *) Do not install the binaries from the support directory twice.
1032 [jun-ichiro hagino <itojun@iijlab.net>]
1034 *) The ap_f* functions should flush data to the filter that is passed
1035 in, not the the filter after the one passed in.
1036 [Ryan Morgan <rmorgan@covalent.net>]
1038 *) Make ab work again by changing its native types to apr types and formats.
1039 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1041 *) Move the byterange filter and all of the supporting functions back
1042 to the HTTP module. The byterange filter turned out to be very
1043 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
1045 *) Make clean, distclean, and extraclean consistently according to the
1046 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
1048 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
1049 This may have been causing problems stopping processes in the threaded
1052 *) Fix content-length in mod_negotiation to a long int representation.
1055 *) Remove BindAddress from the default config file.
1056 [giles@nemeton.com.au]
1058 *) Allow module authors to add a module to their Apache build using
1059 --with-module, without re-running buildconf. The syntax is:
1060 --with-module=module_type:/path/to/module.c
1061 The configure script will copy the module.c file to
1062 modules/module_type, and it will be added to the relevant Makefiles.
1063 currently, this only works for static modules. [Ryan Bloom]
1065 *) Changes required to make prefork clean up idle children properly.
1066 There was a window during which a starting worker deadlocks when
1067 an idle cleanup arrives before it completes init. Apache then keeps
1068 trying to cleanup the same deadlocked worker forever (until higher
1069 pids come along, but it still will never reduce below the deadlocked
1070 pid). Thus the number of children would not reduce to the correct
1071 idle level. [Paul J. Reder]
1073 Changes with Apache 2.0.16
1075 *) Change the default installation directory to /usr/local/apache2,
1076 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
1078 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
1081 *) Get MaxRequestsPerChild working with the Windows MPM.
1084 *) Make generic hooks to work, with mod_generic_hook_import/export
1085 experimental modules. [Ben Laurie, Will Rowe]
1087 *) Fix segfaults for configuration file syntax errors such as
1088 "<Directory>" followed by "</Directory" and
1089 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
1091 *) Cleanup the --enable-layout option of configure. This makes
1092 us use a consistent location for the config.layout file, and it
1093 makes configure more portable.
1094 [jun-ichiro hagino <itojun@iijlab.net>]
1096 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
1097 csv/gnuplot format, rudimentary ssl support and various other tweaks
1098 to make results more true to what is measured. The upshot of this it
1099 turns out that 'ab' has often underreported the true performance of
1100 apache. Often by a order of magnitude :-) See talk/paper of Sander
1101 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
1102 [Dirk-Willem van Gulik]
1104 *) Clean up mod_cgid's temporary request pool. Besides fixing a
1105 storage leak this ensures that some unnecessary pipes are closed.
1108 *) Performance: Add quick_handler hook. This hook is called at the
1109 very beginning of the request processing before location_walk,
1110 translate_name, etc. This hook is useful for URI keyed content
1111 caches like Mike Abbott's Quick Shortcut Cache.
1114 *) top_module global variable renamed to ap_top_module [Perl]
1116 *) Move ap_set_last_modified to the core. This is a potentially
1117 controversial change, because this is kind of HTTP specific. However
1118 many protocols should be able to take advantage of this kind of
1119 information. I expect that headers will need one more layer of
1120 indirection for multi-protocol work, but this is a small step in
1121 the right direction. [Ryan Bloom]
1123 *) Enable mod_status by default. This matches what Apache 1.3 does.
1126 *) Add a ScriptSock directive to the default config file. This is
1127 only enabled when mod_cgid is used.
1128 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1130 Changes with Apache 2.0.15
1132 *) Untangled the buildconf script and eliminated the need for build's
1133 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
1134 libtool muck that is now under srclib/apr/build. [Roy Fielding]
1136 *) Win32: Don't accept more connections than we have worker threads
1140 *) Fix bug in the Unix threaded.c MPM that allowed child processes
1141 to fork() new child processes.
1144 *) Fix a major security problem with double-reverse lookup checking.
1145 Previously, a client connecting over IPv4 would not be matched
1146 properly when the server had an IPv6 listening socket. PR #7407
1147 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
1149 *) Change the way the beos MPM handles polling to allow it to stop and
1150 restart. Problem was the sockets being polled were being reset by
1151 the select call, so once it had accepted a connection it was no
1152 longer listening on the UDP socket we use for shutdown instructions.
1153 APR needs to be altered, patch on it's way. [David Reid]
1155 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
1156 on error exit from ap_getline(). Some other code got upset because
1157 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
1159 *) Handle ap_discard_request_body() being called more than once.
1160 [Greg Ames, Jeff Trawick]
1162 *) Get rid of an inadvertent close of file descriptor 2 in
1163 mod_mime_magic. [Greg Ames, Jeff Trawick]
1165 *) Add a hook, create_request. This hook allows modules to modify
1166 a request while it is being created. This hook is called for all
1167 request_rec's, main request, sub request, and internal redirect.
1168 When this hook is called, the the r->main, r->prev, r->next
1169 pointers have been set, so modules can determine what kind of
1170 request this is. [Ryan Bloom]
1172 *) Cleanup the build process a bit more. The Apache configure
1173 script no longer creates its own helper scripts, it just
1175 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
1177 *) Stop the forced downgrade of the connection to HTTP/1.0 for
1178 proxy requests. [Graham Leggett]
1180 *) Avoid using sscanf to determine the HTTP protocol number in
1181 the common case because sscanf is a performance hog. From
1182 Mike Abbot's Accelerating Apache patch number 6.
1183 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
1185 *) Fix a security exposure in mod_access. Previously when IPv6
1186 listening sockets were used, allow/deny-from-IPv4-address rules
1187 were not evaluated properly (PR #7407). Also, add the ability to
1188 specify IPv6 address strings with optional prefix length on Allow
1189 and Deny. [Jeff Trawick]
1191 *) Enhance rotatelogs so that a UTC offset can be specified, and
1192 the logfile name can be formatted using strftime(3). (Brought
1193 forward from 1.3.) [Ken Coar]
1195 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
1196 DuplicateHandle on an IOCompletionPort (a practice which
1197 MS "discourages"). The new model does not rely on associating
1198 the completion port with the listening sockets, thus the
1199 completion port can be completely managed within the child
1200 process. A dedicated thread accepts connections off the network,
1201 then calls PostQueuedCompletionStatus() to wake up worker
1202 threads blocked on the completion port.
1205 *) Bring forward the --suexec-umask option which allows the
1206 builder to preset the umask for suexec processes. [Ken Coar]
1208 *) Add a -V flag to suexec, which causes it to display the
1209 compile-time settings with which it was built. (Only
1210 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
1212 *) Mod_include should always unset the content-length if the file is
1213 going to be passed through send_parsed_content. There is no to
1214 determine if the content will change before actually scanning the
1215 entire content. It is far safer to just remove the C-L as long
1216 as we are scanning it. [Ryan Bloom]
1218 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
1219 request and not Proxy-Authenticate.
1220 [Graham Leggett <minfrin@sharp.fm>]
1222 Changes with Apache 2.0.14
1224 *) Fix content-length computation. We ONLY compute a content-length if
1225 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
1226 or we already have all the data. [Ryan Bloom]
1228 *) Report unbounded containers in the config file. Previously, a typo
1229 in the </container> directive could result in the rest of the config
1230 file being silently ignored, with undesired defaults used.
1233 *) Make the old_write filter use the ap_f* functions for the buffering.
1236 *) Move more code from the http module into the core server. This
1237 is core code, basically the default handler, the default input
1238 and output filters, and all of the core configuration directives.
1239 All of this code is required in order for the server to work, with or
1240 without HTTP. The server is closer to working without the HTTP
1241 module, although there is still more to do. [Ryan Bloom]
1243 *) Fix a number of SGI compile warnings throughout the server. Fix some
1244 bad parameters to apr_bucket_read(). Fix a bad statement in
1245 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
1246 consistently; we were mixing apr_time_t and time_t in invalid ways
1247 before. In load_file(), call apr_dso_error() instead of
1248 apr_strerror() so that we get a more specific string on some platforms.
1249 PR #6980 [Jeff Trawick]
1251 *) Allow modules to query the MPM about it's execution profile. This
1252 query API can and should be extended in the future, but for now,
1253 max_daemons, and threading or forking is a very good start.
1254 [Jon Travis <jtravis@covalent.net>]
1256 *) Modify mod_include to send blocks of data no larger than 9k.
1257 Without this, mod_include will wait until the whole file is parsed,
1258 or the first tag is found to send any data to the client.
1259 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1261 *) Fix mod_info, so that <Directory> and <Location> directives are
1262 not displayed twice when displaying the current configuration.
1263 [Ryan Morgan <rmorgan@covalent.net>]
1265 *) Add config directives to override DEFAULT_ERROR_MSG and
1266 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
1267 [Dan Rench <drench@xnet.com>]
1269 *) Get mod_info building and loading on Win32. [William Rowe]
1271 *) Begin to move protocol independant functions out of mod_http. The goal
1272 is to have only functions that are HTTP specific in the http directory.
1275 Changes with Apache 2.0.13
1277 *) Don't assume that there will always be multiple calls to the byterange
1278 filter. It is possible that we will need to do byteranges with only
1279 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
1281 *) Move the error_bucket definition from the http module to the
1282 core server. Every protocol will need this ability, not just
1285 Changes with Apache 2.0.12
1287 *) Modify mod_file_cache to save pre-formatted strings for
1288 content-length and last-modified headers for performance.
1289 [Mike Abbot <mja@trudge.engr.sgi.com>]
1291 *) Namespace protect IOBUFSIZ since it is exposed in the API.
1292 [Jon Travis <jtravis@covalent.net>]
1294 *) Use "Basic" authentication instead of "basic" in ab, as the spec
1295 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
1297 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
1298 without ever filling it out. This fixes PR 7271.
1299 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
1300 Cliff Woolley <cliffwoolley@yahoo.com>]
1302 *) Add a couple of GCC attribute tags to printf style functions.
1303 [Jon Travis <jtravis@covalent.net>]
1305 *) Add the correct language tag for interoperation with the Taiwanese
1306 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
1308 *) Migrate the perchild MPM to use the new apr signal child, and
1309 APR thread functions. [Ryan Bloom]
1311 *) Close one copy of the CGI's stdout before creating the new process.
1312 The CGI will still have stdout, because we have already dup'ed it.
1313 This keeps Apache from waiting forever to send the results of a CGI
1314 process that has forked a long-lived child process.
1315 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
1317 *) Remove the rest of the pthreads functions from the threaded MPM.
1318 This requires the APR support for a signal thread that was just
1321 *) Make mod_dir use a fixup for sending a redirect to the browser.
1322 Before this, we were using a handler, which doesn't make much
1323 sense, because the handler wasn't generating any data, it would
1324 either return a redirect error code, or DECLINED. This fits the
1325 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1327 *) Make the threaded MPM use APR threads instead of pthreads.
1330 *) Get mod_tls to the point where it actually appears to work in all cases.
1333 *) implement --enable-modules and --enable-mods-shared for "all" and
1334 "most". [Greg Stein]
1336 *) Move the threaded MPM to use APR locks instead of pthread locks.
1339 *) Rename mpmt_pthread to threaded. This is more in line with the
1340 fact that mpmt_pthread shouldn't be using pthreads directly, and
1341 it is a smaller name that doesn't tie into anything.
1344 *) Rename the module structures so that the exported symbol matches
1345 the file name, and it is easier to automate the installation
1346 process (generating LoadModule directives from the module filenames).
1349 *) Remove the coalesce filter. With the ap_f* functions, this filter
1350 is no longer needed. [Ryan Bloom]
1352 Changes with Apache 2.0.11
1354 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1355 added feature of allowing a uid/gid per child process. If no
1356 uid/gid is specified, then Perchild behaves exactly like dexter.
1359 *) Get perchild building again. [Ryan Bloom]
1361 *) Don't disable threads just because we are using the prefork MPM.
1362 If somebody wants to compile without threads, they must now add
1363 --disable-threads to the configure command line. [Ryan Bloom]
1365 *) Begin to move the calls to update_child_status into common code, so
1366 that each individual MPM does not need to update the scoreboard itself.
1369 *) Allow mod_tls to compile under Unix boxes where openssl has been
1370 installed to the system include files.
1371 [Gomez Henri <new-httpd@slib.fr>]
1373 *) Cleanup the mod_tls configure process. This should remove any need
1374 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1375 configure doesn't check that yet. [Ryan Bloom]
1377 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1378 vital that you read modules/tls/README before attempting to build
1381 *) Fix a potential seg fault on all platforms. David Reid fixed this
1382 on BEOS, but the problem could happen anywhere, so we don't want
1383 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1385 *) Add new LogFormat directive, %D, to log time it takes to serve a
1386 request in microseconds. [Bill Stoddard]
1388 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1389 SetOutputFilter. This corresponds nicely with the other Set
1390 directives, which operate on containers while the Add* directives
1391 tend to work directly on extensions. [Ryan Bloom]
1393 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1394 functions for the buffering so that we don't need to compute
1395 the length of the headers before we actually create the header
1396 buffer. [Ryan Bloom]
1398 *) Allow filters to buffer data using the ap_f* functions. These have
1399 become macros that resolve directly to apr_brigade_*.
1402 *) Get the Unix MPM's to do a graceful restart again. If we are going
1403 to register a cleanup with ap_cleanup_scoreboard, then we have to
1404 kill the cleanup with the same function, and that function can't be
1405 static. [Ryan Bloom]
1407 *) Install all required header files. Without these, it was not
1408 possible to compile some modules outside of the server.
1411 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1412 forward from 1.3 to 2.0, we missed a single line, which broke regex
1413 aliases. [Ryan Bloom]
1415 *) We have a poor abstraction in the protocol. This is a temporary
1416 hack to fix the bug, but it will need to be fixed for real. If
1417 we find an error while sending out a custom error response, we back
1418 up to the first non-OK request and send the data. Then, when we send
1419 the EOS from finalize_request_protocol, we go to the last request,
1420 to ensure that we aren't sending an EOS to a request that has already
1421 received one. Because the data is sent on a different request than
1422 the EOS, the error text never gets sent down the filter stack. This
1423 fixes the problem by finding the last request, and sending the data
1424 with that request. [Ryan Bloom]
1426 *) Make the server status page show the correct restart time, and
1427 thus the proper uptime. [Ryan Bloom]
1429 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1430 should reduce the amount of duplicate code that is required to
1431 create CGI processes.
1432 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1434 *) ap_new_connection() closes the socket and returns NULL if a socket
1435 call fails. Usually this is due to a connection which has been
1436 reset. [Jeff Trawick]
1438 *) Move the Apache version information out of httpd.h and into release.h.
1439 This is in preparation for the first tag with the new tag and release
1440 system. [Ryan Bloom]
1442 *) Begin restructuring scoreboard code to enable adding back in
1443 the ability to use IPC other than shared memory.
1444 Get mod_status working on Windows again. [Bill Stoddard]
1446 *) Make mod_status work with 2.0. This will work for prefork,
1447 mpmt_pthread, and dexter. [Ryan Bloom]
1449 *) Correct a typo in httpd.conf.
1450 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1452 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1454 *) Get the correct IP address if ServerName isn't set and we can't
1455 find a fully-qualified domain name at startup.
1456 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1458 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1460 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1461 'extra' stat's for user/group since they should never occur, and now
1462 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1463 volumes. [William Rowe]
1465 *) Adopt apr features to simplify mod_includes. This changes the
1466 behavior of the USER_NAME variable, unknown uid's are now reported
1467 as USER_NAME="<unknown>" rather than the old user#000 result.
1468 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1470 *) Adopt apr features for simplifing mod_userdir, and accept the new
1471 Win32/OS2 exceptions without hiccuping. [William Rowe]
1473 *) Replace configure --with-optim option by using and saving the
1474 environment variable OPTIM instead. This is needed because configure
1475 options do not support multiple flags separated by spaces.
1478 *) Fix some byterange handling. If we get a byte range that looks like
1479 "-999999" where that is past the end of the file, we should return
1480 a PARTIAL CONTENT status code, and return the whole file as one big
1481 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1483 *) Make the error bucket a real meta-data bucket. This means that the
1484 bucket length is 0, and a read returns NULL data. If one of these
1485 buckets is passed down after the headers are sent, this data will
1486 just be ignored. [Greg Stein]
1488 *) The prefork MPM wasn't killing child processes correctly if a restart
1489 signal was received while the process was serving a request. The child
1490 process would become the equivalent of a second parent process. If
1491 we break out of the accept loop, then we need to do die after cleaning
1492 up after ourselves. [Ryan Bloom]
1494 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1495 restarts. [Ryan Bloom]
1497 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1498 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1499 performing very expensive owner, group and permission lookups
1500 and allows the server to function until these apr_finfo_t fields
1501 are implemented under Win32. [William Rowe]
1503 *) Support for typedsafe optional functions - that is functions exported by
1504 optional modules, which, therefore, may or may not be present, depending
1505 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1506 for sample code. [Ben Laurie]
1508 *) filters can now report an HTTP error to the server. This is done
1509 by sending a brigade where the first bucket is an error_bucket.
1510 This bucket is a simple bucket that stores an HTTP error and
1511 a string. Currently the string is not used, but it may be needed
1512 to output an error log. The http_header_filter will find this
1513 bucket, and output the error text, and then return
1514 AP_FILTER_ERROR, which informs the server that the error web page
1515 has already been sent. [Ryan Bloom]
1517 *) If we get an error, then we should remove all filters except for
1518 those critical to serving a web page. This fixes a bug, where
1519 error pages were going through the byterange filter, even though
1520 that made no sense. [Ryan Bloom]
1522 *) Relax the syntax checking of Host: headers in order to support
1523 iDNS. PR#6635 [Tony Finch]
1525 *) Cleanup the byterange filter to use the apr_brigade_partition
1526 and apr_bucket_copy functions. This removes a lot of very messy
1527 code, and hopefully makes this filter more stable.
1530 *) Remove AddModule and ClearModuleList directives. Both of these
1531 directives were used to ensure that modules could be enabled
1532 in the correct order. That requirement is now gone, because
1533 we use hooks to ensure that modules are in the correct order.
1536 *) When SuExec is specified, we need to add it to the list of
1537 targets to be built. If we don't, then any changes to the
1538 configuration won't affect SuExec, unless 'make suexec' is
1539 specifically run. [Ryan Bloom]
1541 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1542 the APR_XTHREAD argument to open a file for consumption by
1543 parallel threads on win32. [William Rowe]
1545 *) Correct a bug in determining when we follow symlinks. The code
1546 expected a stat -1 result, not an apr_status_t positive error.
1547 Also check if the APR_FINFO_USER fields are valid before we
1548 follow the link. [William Rowe]
1550 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1551 mpm_common.c. These functions are only valid on some platforms,
1552 so they should not be in the main-line code. [Ryan Bloom]
1554 *) Remove ap_chdir_file(). This function is not thread-safe,
1555 and nobody is currently using it. [Ryan Bloom]
1557 *) Do not try to run make depend if there are no .c files in the
1558 current directory, doing so makes `make depend` fail.
1561 *) Update highperformance.conf to work with either prefork or
1562 pthreads mpms. [Greg Ames]
1564 *) Stop checking to see if this is a pipelined request if we know
1565 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1566 This keeps us from making an extra read call when serving a 1.0
1567 request. [Ryan Bloom and Greg Stein]
1569 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1570 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1571 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1573 *) Fix the RFC number mentioned when complaining about a missing
1574 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1576 *) Fix an endless loop in ab which occurred when ab was posting
1577 and the server dropped the connection unexpectedly.
1580 *) Fix a segfault while handling request bodies in ap_http_filter().
1581 This problem has been seen with mod_dav usage as well as with
1582 requests where the body was just being discarded. [Jeff Trawick]
1584 *) Some adjustment on the handling and automatic setting (via
1585 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1586 add the capability to specify flags (NOTEST_CFLAGS and
1587 NOTEST_LDFLAGS) which are used to compile Apache, but
1588 not used during the configuration process. Useful for
1589 flags like "-Werror". [Jim Jagielski]
1591 *) Stop using environment variables to force debug mode or
1592 no detach. We now use the -D command line argument to
1593 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1594 [Greg Stein, Ryan Bloom]
1596 *) Change handlers to use hooks. [Ben Laurie]
1598 *) Stop returning copies of filenames from both apr_file_t and
1599 apr_dir_t. We pstrdup the filenames that we store in the
1600 actual structures, so we don't need to pstrdup the strings again.
1603 *) mod_cgi: Fix some problems where the wrong error value was being
1604 traced. [Jeff Trawick]
1606 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1609 *) Add generic hooks. [Ben Laurie]
1611 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1613 *) Fix a segfault caused by mod_ext_filter when the external filter
1614 program does not exist. [Jeff Trawick]
1616 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1617 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1618 was served through mod_charset_lite (or anything else that would
1619 create a transient bucket in this size range). ap_bucket_make_heap()
1620 silently failed (fixed), transient_setaside() discovered it, but
1621 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1623 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1624 is that some browsers send extra lines at the end of POST requests, and
1625 we don't want to delay sending data back to the user just because the
1626 browser isn't well behaved. [Ryan Bloom]
1628 *) Get SuEXEC working again. We can't send absolute paths to suExec
1629 because it refuses to execute those programs. SuEXEC also wasn't
1630 always recognizing configuration changes made using the autoconf
1633 *) Allow the buildconf process to find the config.m4 files in the correct
1634 order. Basically, we can now name config.m4 files as config\d\d.m4,
1635 and we will sort them correctly when inserting them into the build
1636 process. [Ryan Bloom]
1638 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1639 This also allows mod_cgid to use ap_os_create_priviledged_process,
1640 thus allowing for SuExec execution from mod_cgid. Currently, we do
1641 not support everything that standard SuExec supports, but at least
1642 it works minimally now. [Ryan Bloom]
1644 *) Allow SuExec to be configured from the ./configure command line.
1647 *) Update some of the docs in README and INSTALL to reflect some of
1648 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1650 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1651 need to call sendfile again. This gets us serving large files
1652 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1654 *) Get the support programs building cleanly again.
1655 [Cliff Woolley <cliffwoolley@yahoo.com>]
1657 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1658 current directory logic now backs up over bin/ to determine the
1659 server root from the Apache.exe path.
1661 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1662 loadable modules, dynamic libs are all named libfoo.dll, and the
1663 makefile.win populates the include, lib and libexec directories.
1665 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1666 Apache gets IPv6 listening sockets by default. Additionally, the
1667 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1668 numeric address strings (e.g., "Listen [fe80::1]:8080").
1671 *) Modify the install directory layout. Modules are now installed in
1672 modules/. Shared libraries should be installed in libraries/, but
1673 we don't have any of those on Unix yet. All install directories
1674 are modifyable at configure time. [Ryan Bloom]
1676 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1678 *) Get the functions in server/linked into the server, regardless of
1679 which modules linked into the server. This uses the same hack
1680 for Apache that we use for APR and apr-util to ensure all of the
1681 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1682 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1683 the scripts a bit easier.
1686 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1687 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1689 *) Get all of the auth modules to the point that they will install and
1690 be loadable into the server. Our new build/install mechanism expects
1691 that all modules will have a common name format. The auth modules
1692 didn't use that format, so we didn't install them properly.
1695 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1696 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1698 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1700 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1701 after the end of the response. [Ryan Bloom]
1703 *) Get byterange requests working with responses that do not have a
1704 content-length. Because of the way byterange requests work, we have to
1705 have all of the data before we can actually do the byterange, so we
1706 can compute the content-length in the byterange filter.
1709 *) Get exe CGI's working again on Windows.
1712 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1713 they keep track of whether or not their post config hook has been
1714 called before. Instead of a static variable (which is replaced when
1715 the DSO is loaded a second time), use userdata in the process pool.
1718 Changes with Apache 2.0a9
1720 *) Win32 now requires perl to complete the final install step for users
1721 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1722 and installs the conf, htdocs and htdocs/manual directories.
1725 *) Make mod_include use a hash table to associate directive tags with
1726 functions. This allows modules to implement their own SSI tags easily.
1727 The idea is simple enough, a module can insert it's own tag and function
1728 combination into a hash table provided by mod_include. While mod_include
1729 parses an SSI file, when it encounters a tag in the file, it does a
1730 hash lookup to find the function that implements that tag, and passes
1731 all of the relevant data to the function. That function is then
1732 responsible for processing the tag and handing the remaining data back
1733 to mod_include for further processing.
1734 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1736 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1737 fewer parameters: the local and remote socket addresses were removed
1738 from the parameter list because all required information is available
1739 via the APR socket. [Jeff Trawick]
1741 *) Distribution directory structure reorganized to reflect a
1742 normal source distribution with external install targets.
1745 *) The MPMs that need multiple segments of shared memory now create
1746 two apr_shmem_t variables, one for each shared memory allocation.
1747 the problem is that we can't determine how much memory will be required
1748 for shared memory allocations once we try to allocate more than one
1749 variable. The MM code automatically aligns the shared memory allocations,
1750 so we end up needing to pad the amount of shared memory we want based
1751 on how many variables will be allocated out of the shared memory segment.
1752 It is just easier to create a second apr_shmem_t variable, and two
1753 shmem memory blocks.
1756 *) Cleanup the export list a bit. This creates a single unified list of
1757 functions exported by APR. The export list is generated at configure
1758 time, and that list is then used to generate the exports.c file.
1759 Because of the way the export list is generated, we only export those
1760 functions that are valid on the platform we are building on.
1763 *) Enable logging the cookie with mod_log_config
1764 [Sander van Zoest <sander@covalent.net>]
1766 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1769 *) Added lib/aputil/ as a placeholder for utility functions which are not
1770 specific to the Apache HTTP Server (but do not make sense with APR).
1771 The first utility is "apu_dbm": a set of functions to work with DBM
1772 files. This first version can be compiled for SDBM or GDBM databases.
1775 *) Complete re-write of mod_include. This makes mod_include a filter that
1776 uses buckets directly. This has now served the FAQ correctly.
1777 [Paul Reder <rederpj@raleigh.ibm.com>]
1779 *) Allow modules to specify the first filter in a sub_request when
1780 making the sub_request. This keeps modules from having to change the
1781 output_filter immediately after creating the sub-request, and therefore
1782 skip the sub_req_output_filter. [Ryan Bloom]
1784 *) Update ab to accept URLs with IPv6 literal address strings (in the
1785 format described in RFC 2732), and to build Host header fields in
1786 the same format. This allows IPv6 literal address strings to be
1787 used with ab. This support has been tested against Apache 1.3 with
1788 the KAME patch, but Apache 2.0 does not yet work with this format
1789 of the Host header field. [Jeff Trawick]
1791 *) Accomodate an out-of-space condition in the piped logs and the
1792 rotatelogs.c code, and no longer churn log processes for this
1793 condition. [Victor J. Orlikowski]
1795 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1798 Changes with Apache 2.0a8
1800 *) Add a directive to mod_mime so that filters can be associated with
1804 *) Get multi-views working again. We were setting the path_info
1805 field incorrectly if we couldn't find the specified file.
1808 *) Fix 304 processing. The core should never try to send the headers
1809 down the filter stack. Always, just setup the table in the request
1810 record, and let the header filter convert it to data that is ready
1814 *) More fixes for the proxy. There are still bugs in the proxy code,
1815 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1819 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1822 *) APR: Add new apr_getopt_long function to handle long options.
1823 [B. W. Fitzpatrick <fitz@red-bean.com>]
1825 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1826 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1827 hostname resolution/address string parsing and building
1828 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1829 of one of the apr_sockaddr_t structures for a socket. Change
1830 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1832 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1833 I have proxied pages with it, cleanup will commence soon.
1836 *) Make the proxy work with filters. This isn't perfect, because we
1837 aren't dealing with the headers properly. [Ryan Bloom]
1839 *) Do not send a content-length iff the C-L is 0 and this is a head
1840 request. [Ryan Bloom]
1842 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1843 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1845 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1847 *) Get the default_handler to stop trying to deal with HEAD requests.
1848 The idea is to let the content-length filter compute the C-L before
1849 we try to send the data. If we can get the C-L correctly, then we
1850 should send it in the HEAD response.
1853 *) The Header filter can now determine if a body should be sent based
1854 on r->header_only. The general idea of this is that if we delay
1855 deciding to send the body, then we might be able to compute the
1856 content-length correctly, which will help caching proxies to cache
1857 our data better. Any handler that doesn't want to try to compute
1858 the content-length can just send an EOS bucket without data and
1859 everything will just work.
1862 *) Add the referer to the error log if one is available.
1863 [Markus Gyger <mgyger@itr.ch>]
1865 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1866 change, the root of the configuration tree has been exposed to modules
1868 [Ryan Morgan <rmorgan@covalent.net>]
1870 *) Get the core_output_filter to use the bucket interface directly.
1871 This keeps us from calling the content-length filter multiple times
1872 for a simple static request.
1875 *) We are sending the content-type correctly now.
1876 [Ryan Bloom and Will Rowe]
1878 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1879 a bogus bytes-sent value when the only thing being sent was trailers
1880 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1882 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1883 hints file to determine which platforms define
1884 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1887 *) APR: add apr_get_home_directory() [Jeff Trawick]
1889 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1891 *) Not all platforms have INADDR_NONE defined by default. Apache
1892 used to make this check and define INADDR_NONE if appropriate,
1893 but APR needs the check too, and I suspect other applications will
1894 as well. APR now defines APR_INADDR_NONE, which is always a valid
1895 value on all platforms.
1896 [Branko Èibej <brane@xbc.nu>]
1898 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1899 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1901 *) Relax the syntax checking of Host: headers in order to support
1902 iDNS. PR#6635 [Tony Finch]
1904 *) When reading from file buckets we convert to an MMAP if it makes
1905 sense. This also simplifies the default handler because the
1906 default handler no longer needs to try to create MMAPs.
1909 *) BUFF has been removed from the main server. The BUFF code will remain
1910 in the code until it has been purged from the proxy module as well.
1913 *) Byteranges have been completely re-written to be a filter. This
1914 has been tested, and I believe it is working correctly, but it could
1915 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1916 the output from 1.3, the only difference being that 1.3 includes
1917 a content-length in the response, and this does not.
1920 *) APR read/write functions and bucket read functions now operate
1921 on unsigned integers, instead of signed ones. It doesn't make
1922 any sense to use signed ints, because we return the error codes,
1923 so if we have an error we should report 0 bytes read or written.
1926 *) Always compute the content length, whether it is sent or not.
1927 The reason for this, is that it allows us to correctly report
1928 the bytes_sent when logging the request. This also simplifies
1929 content-length filter a bit, and fixes the actual byte-reporing
1930 code in mod_log_config.c
1933 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1934 it says, because it was only used by EOS and FLUSH buckets. Since
1935 neither of those are required at the end of a brigade, this was
1936 really signifying FLUSH_THE_DATA, but that can be determined better
1937 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1938 buckets now return a length of 0, which is actually the amount of data
1939 read, so they make more sense.
1942 *) Allow the core_output_filter to save some data past the end of a
1943 request. If we get an EOS bucket, we only send the data if it
1944 makes sense to send it. This allows us to pipeline request
1945 responses. As a part of this, we also need to allocate mmap
1946 buckets out of the connection pool, not the request pool. This
1947 allows the mmap to outlive the request.
1950 *) Make blocking and non-blocking bucket reads work correctly for
1951 sockets and pipes. These are the only bucket types that should
1952 have non-blocking reads, because the other bucket types should
1953 ALWAYS be able to return something immediately.
1956 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1957 server, but use Ctrl+Break to initiate a graceful restart
1958 instead of duplicating behavior. [John Sterling]
1960 *) Patch mod_autoindex to set the Last-Modified header based on
1961 the directory's mtime, and add the ETag header. [William Rowe]
1963 *) Merge the 1.3 patch to add support for logging query string in
1964 such a way that "%m %U%q %H" is the same as "%r".
1967 *) Port three log methods from mod_log_config 1.3 to 2.0:
1968 CLF compliant '-' byte count, method and protocol.
1971 *) Add a new LogFormat directive, %c, that will log connection
1972 status at the end of the response as follows:
1973 'X' - connection aborted before the response completed.
1974 '+' - connection may be kept-alive by the server.
1975 '-' - connection will be closed by the server.
1978 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1979 Unicode file names and paths for Win32, and tag the Content-Type
1980 from mod_autoindex to reflect that charset if the the feature
1981 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1983 *) Compute the content length (and add appropriate header field) for
1984 the response when no content length is available and we can't use
1985 chunked encoding. [Jeff Trawick]
1987 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1988 so that content input filters get dechunked data when using
1989 the default handler. Also removed REQUEST_CHUNKED_PASS.
1992 *) Add mod_ext_filter as an experimental module. This module allows
1993 the administrator to use external programs as filters. Currently,
1994 only filtering of output is supported. [Jeff Trawick]
1996 *) Most Apache functions work on EBCDIC machines again, as protocol
1997 data is now translated (again). [Jeff Trawick]
1999 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
2000 the EBCDIC support. They are noops on ASCII machines, so this
2001 type of translation doesn't have to be surrounded by #ifdef
2002 CHARSET_EBCDIC. [Jeff Trawick]
2004 *) Fix mod_include. tag commands work again, and the server will
2005 send the FAQ again. This also allows mod_include to set aside
2006 buckets that include partial buckets.
2007 [Ryan Bloom and David Reid]
2009 *) Add suexec support back. [Manoj Kasichainula]
2011 *) Lingering close now uses the socket directly instead of using
2012 BUFF. This has been tested, but since all we can tell is that it
2013 doesn't fail, this needs to be really hacked on.
2016 *) Allow filters to modify headers and have those headers be sent to
2017 the client. The idea is that we have an http_header filter that
2018 actually sends the headers to the network. This removes the need
2019 for the BUFF to send headers.
2022 *) Charset translation: mod_charset_lite handles translation of
2023 request bodies. Get rid of the xlate version of ap_md5_digest()
2024 since we don't compute digests of filtered (e.g., translated)
2025 response bodies this way anymore. (Note that we don't do it at
2026 all at the present; somebody needs to write a filter to do so.)
2029 *) Input filters and ap_get_brigade() now have a input mode parameter
2030 (blocking, non-blocking, peek) instead of a length parameter.
2033 *) Update the mime.types file to the registered media types as
2034 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
2037 *) Namespace protect some macros declared in ap_config.h
2040 *) Support HTTP header line folding with input filtering.
2043 *) Mod_include works again. This should still be re-written, but at
2044 least now we can serve an SHTML page again.
2047 *) Begin to remove BUFF from the core. Currently, we keep a pointer
2048 to both the BUFF and the socket in the conn_rec. Functions that
2049 want to use the BUFF can, functions that want to use the socket,
2050 can. They point to the same place.
2053 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
2054 [Tomas "Ögren" <stric@ing.umu.se>]
2056 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
2057 associated pool goes away. (APR pipes on OS/2 were already had this
2058 logic.) This resolvs a fatal file descriptor leak with CGIs.
2061 *) The final line of the config file was not being read if there was
2062 no \n at the end of it. This was caused by apr_fgets returning
2063 APR_EOF even though we had read valid data. This is solved by
2064 making cfg_getline check the buff that was returned from apr_fgets.
2065 If apr_fgets return APR_EOF, but there was data in the buf, then we
2066 return the buf, otherwise we return NULL.
2069 *) Piped logs work again in the 2.0 series.
2072 *) Restore functionality broken by the mod_rewrite security fix:
2073 rewrite map lookup keys and default values are now expanded
2074 so that the lookup can depend on the requested URI etc.
2075 PR #6671 [Tony Finch]
2077 *) Tighten up the syntax checking of Host: headers to fix a
2078 security bug in some mass virtual hosting configurations
2079 that can allow a remote attacker to retrieve some files
2080 on the system that should be inaccessible. [Tony Finch]
2082 *) Add a pool bucket type. This bucket is used for data allocated out
2083 of a pool. If the pool is cleaned before the bucket is destroyed, then
2084 the data is converted to a heap bucket, allowing it to survive the
2088 *) Add a flush bucket. This allows modules to signal that the filters
2089 should all flush whatever data they currently have. There is no way
2090 to actually force them to do this, so if a filter ignores this bucket,
2091 that's life, but at least we can try with this.
2094 *) Add an output filter for sub-requests. This filter just strips the
2095 EOS bucket so that we don't confuse the main request's core output
2096 filter by sending multiple EOS buckets. This change also makes sub
2097 requests start to send EOS buckets when they are finished.
2100 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
2101 makes ap_bucket_destroy a return void, which is okay because it
2102 used to always return APR_SUCCESS, and nobody ever checked its
2103 return value anyway.
2104 [Cliff Woolley <cliffwoolley@yahoo.com>]
2106 *) Remove the index into the bucket-type table from the buckets
2107 structure. This has now been replaced with a pointer to the
2108 bucket_type. Also add some macros to test the bucket-type.
2111 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
2112 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
2113 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
2114 All _VAR_ flavors changes to _DATA to be absolutely clear.
2117 *) Add support for /, //, //servername and //server/sharename
2118 parsing of <Directory> blocks under Win32 and OS2.
2119 [Tim Costello, William Rowe, Brian Harvard]
2121 *) Remove the function pointers from the ap_bucket type. They have been
2122 replaced with a global table. Modules are allowed to register bucket
2123 types and use then use those buckets.
2126 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
2127 once we finish writing the request body to the cgi child process;
2128 otherwise, the client doesn't hit EOF on stdin. Small request bodies
2129 worked without this change (for reasons I don't understand), but large
2130 ones didn't. [Jeff Trawick]
2132 *) Remove file bucket specific information from the ap_bucket type.
2133 This has been moved to a file_bucket specific type that hangs off
2134 the data pointer in the ap_bucket type.
2137 *) Input filtering now has a third argument. This is the amount of data
2138 to read from lower filters. This argument can be -1, 0, or a positive
2139 number. -1 means give me all the data you have, I'll deal with it and
2140 let you know if I need more. 0 means give me one line and one line
2141 only. A positive number means I want no more than this much data.
2143 Currently, only 0 and a positive number are implemented. This allows
2144 us to remove the remaining field from the conn_rec structure, which
2148 *) Big cleanup of the input filtering. The goal is that http_filter
2149 understands two conditions, headers and body. It knows where it is
2150 based on c->remaining. If c->remaining is 0, then we are in headers,
2151 and http_filter returns a line at a time. If it is not 0, then we are
2152 in body, and http_filter returns raw data, but only up to c->remaining
2153 bytes. It can return less, but never more.
2154 [Greg Ames, Ryan Bloom, Jeff Trawick]
2156 *) mod_cgi: Write all of the request body to the child, not just what
2157 the kernel would accept on the first write. [Jeff Trawick]
2159 *) Back out the change that moved the brigade from the core_output_filters
2160 ctx to the conn_rec. Since all requests over a given connection
2161 go through the same core_output_filter, the ctx pointer has the
2165 *) Fix another bug in the send_the_file() read/write loop. A partial
2166 send by apr_send would cause unsent data in the read buffer to
2167 get clobbered. Complete making send_the_file handle partial
2168 writes to the network.
2171 *) Fix a couple of type fixes to allow compilation on AIX again
2172 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
2174 *) Fix bug in send_the_file() which causes offset to be ignored
2175 if there are no headers to send.
2178 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
2179 filter. Useful for supporting Windows 9* with a binary
2180 compiled on Windows NT.
2183 Changes with Apache 2.0a7
2185 *) Reimplement core_output_filter to buffer/save bucket brigades
2186 across multiple calls to the core_filter. The brigade will be
2187 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
2188 thresholds are hit or the EOS bucket is received.
2191 *) Create experimental filter (buffer_filter) that coalesces bytes
2192 into one large buffer before invoking the next filter in the
2193 chain. This filter is particularly useful with the current
2194 implementation of mod_autoindex when it inserted above the
2195 chunk_filter. mod_autoindex generates a lot of brigades that
2196 containing buckets holding just a few bytes each. The
2197 buffer_filter coalesces these buckets into a single large bucket.
2200 *) Add apr_sendfile() support into the core_output_filter.
2203 *) Add apr_sendv() support into the core_output_filter.
2206 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
2207 [Mike Abbott <mja@sgi.com>]
2209 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
2210 make much sense, because Apache uses buckets instead of BUFFs now.
2213 *) send_the_file now falls back to a read/write loop on platforms that
2214 do not have sendfile.
2215 [Ryan Bloom and Brian Havard]
2217 *) Install apachectl correctly, and substitute the proper values so
2218 that it works again. [Ryan Bloom]
2220 *) Better(??) handle platforms that lack sendfile().
2223 *) APR now has UUID generation/formatting/parsing support.
2226 *) Begin the http_filter. This is an input filter that understands
2227 the absolute basic amount required to parse an HTTP Request. The
2228 goal is to be able to split headers from request body before passing
2229 the data back to the other filters.
2232 *) Bring forward from 1.3.13 the config directory implementation
2235 *) install apxs if it is created
2238 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
2239 conversions. [William Rowe]
2241 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
2242 ap_add_output_filter(). [Jeff Trawick]
2244 *) Multiple build and configuration fixes
2247 -add datadir and localstatedir substitutions
2249 -fix logfilename misspelling
2250 -fix evaluation of installation dir variables and
2251 -replace $foobar by $(foobar) to be usefull in the makefile
2255 -add rules for cross-compiling in rules.mk. Okay, rule to check for
2256 $CC_FOR_BUILD is still missing
2257 -use CHECK_TOOL instead of CHECK_PROG for ranlib
2258 -add missing "AR=@AR@" to severaly Makefile.in's
2259 -cache result for "struct rlimit"
2260 -compile all helper programs with native and cross compiler
2261 and use the native version to generate header file
2262 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2264 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
2266 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
2268 *) Fix a bug where a client which only sends \n to delimit header
2269 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
2270 message. Start working on ebcdic co-existance with input
2272 [William Rowe, Greg Ames]
2274 *) If mod_so is enabled in the server always create libexec, even
2275 if there are no modules installed in this directory. This is a
2276 requirement for APXS to work correctly.
2279 *) Connection oriented output filters are now stored in the
2280 conn_rec instead of the request_rec. This allows us to add the
2281 output filter in the pre-connection phase instead of the
2282 post_read_request phase, which keeps us from trying to write an
2283 error page before we have a filter to write to the network.
2284 [Ryan Bloom, Jeff Trawick, and Greg Ames]
2286 *) Cleaning up an mmap bucket no longer deletes the mmap. An
2287 mmap can be used across multiple buckets (default_handler with
2288 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
2289 the mmap itself can't be associated with the bucket.
2292 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
2295 *) Radical surgery to improve mod_isapi support under Win32.
2296 Includes a number of newer ServerSupportFunction calls, support
2297 for ReadClient (in order to retrieve POSTs greater than 48KB),
2298 and general bug fixes to more reliably load ISAPI .dll's and
2299 prevent leaking handle resources. Note: There are still
2300 discrepancies between IIS's and Apache's ServerVariables, and
2301 async calls are still not supported. Additional warnings are
2302 logged to facilitate debugging of unsupported ISAPI calls.
2305 *) Add input filtering to Apache. The basic idea for the input
2306 filters is the same as the ideas for output filters. The biggest
2307 difference is that instead of calling ap_pass_brigade, ap_get_brigade
2308 should be called, and the order of execution for the filter itself is
2309 different. When writing an output filter, a brigade is passed in,
2310 and filters operate directly on that brigade, when done, they call
2311 ap_pass_brigade. Input filters are the exact opposite. Because input
2312 is not a push operation, filters first call ap_get_brigade. When this
2313 function returns, the input filter will be left with a valid brigade.
2314 The input filter should then operate on the brigade, and return.
2317 *) Fix building on BSD/OS using its native make. The build system
2318 falls back to the BSD .include directive on that host platform.
2321 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
2322 SHA1 and plaintext password encodings. Make feature tests a
2323 bit more flexible. [William Rowe]
2325 *) Charset translation: mod_charset_lite handles output content
2326 translation in a filter. mod_charset_lite no longer ignores
2327 subrequests. A bunch of cruft related to BUFF's support for
2328 translating request and response bodies was removed.
2331 *) Move the addition of the CORE filter to the post_read_request
2332 hook in http_core.c. This removes the need to add the filter in
2333 multiple places and allows for an SSL module to be added much
2334 simpler. [Ryan Bloom]
2336 *) Fix a security problem that affects certain configurations of
2337 mod_rewrite. If the result of a RewriteRule is a filename that
2338 contains expansion specifiers, especially regexp backreferences
2339 $0..$9 and %0..%9, then it may be possible for an attacker to
2340 access any file on the web server. [Tony Finch]
2342 *) Fix a bug where errors that are detected during early request parsing
2343 don't produce visible HTTP error messages at the browser, because
2344 the core_filter wasn't present. [Greg Ames]
2346 *) Provide apr_socklen_t as a portability aid.
2347 [Victor J. Orlikowski]
2349 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2350 as well as a comment arg to the add, adduser and update cmds.
2351 update allows the user to clear or preserve pw/groups/comment.
2352 Fixed a bug in dbmmanage that prevented the check option from
2353 parsing a password followed by :group... text. Corrected the
2354 seed calcualation for Win32 systems, and added -lsdbm support.
2357 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2360 *) Avoid a segfault when parsing .htaccess files. An
2361 uninitialized tree pointer was passed to ap_build_config().
2364 *) Change the way that inet_addr & inet_network are checked for
2365 in APR's configure process to allow BeOS BONE to correctly
2366 find them. With this change BeOS BONE now builds from source
2367 with no problems. [David Reid]
2369 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2370 the end of the parameters to execve() was stored in the wrong
2371 location, overlaying the storage beyond the newargs[] array and
2372 also passing uninitialized storage to execve(), which would
2373 sometimes fail with EFAULT. [Jeff Trawick]
2375 *) Fix a bug parsing configuration file containers. With a sequence
2376 like this in the config file
2378 <IfModule mod_kilroy.c>
2381 <IfModule mod_lovejoy.c>
2386 the second container would be terminated at the blank line due to
2387 sediment in the buffer from reading the prior </IfModule> and an
2388 error message would be generated for the real </IfModule> for the
2389 second container. Also due to this problem, any two characters
2390 could be used for "</" in the close of a container.
2393 *) ap_add_filter prototype changed to remove the ctx pointer. The
2394 pointer still remains in the filter structure, but it can not be
2395 a part of the ap_add_filter prototype. The reason is that when
2396 the core uses AddFilter to add a filter to the stack it doesn't
2397 know how to allocate the ctx pointer, or even how much memory should
2398 be allocated. The filters will have to be responsible for allocating
2399 the ctx memory when they need it.
2402 *) Add an AddFilter directive. This directive takes a list of filters
2403 that should be activated for the requested resource.
2406 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2407 some other platforms). [Jeff Trawick]
2409 *) Modify mod_include to be a filter. Currently, it has only been tested
2410 on actual files, but it should work for CGI scripts too.
2413 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2414 writes. apr_flush() for Unix: handle interrupted writes.
2417 *) NameVirtualHost can now take "*" as an argument instead of
2418 an IP address. This allows you to create a purely name-based
2419 virtual hosting server that does not have any IP addresses in
2420 the configuration file and which ignores the local address
2421 of any connections. PR #5595, PR #4455 [Tony Finch]
2423 *) Fix some compile warnings in mod_mmap_static.c
2424 [Mike Abbott <mja@sgi.com>]
2426 *) Fix chunking problem with CGI scripts. The general problem was that
2427 the CGI modules were adding an EOS bucket and then the core added an
2428 EOS bucket. The chunking filter finalizes the chunked response when it
2429 encounters an EOS bucket. Because two EOS buckets were sent, we
2430 finalized the response twice. The fix is to make sure we only send one
2431 EOS, by utilizing a flag in the request_rec.
2434 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2435 and Win32. Previously, the first read from an apr_file_t set up via
2436 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2438 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2439 bucket, instead of using BUFF's and ap_r*.
2442 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2443 [Mike Abbott <mja@sgi.com>]
2445 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2446 code to use APR file's directly instead of going through BUFFs.
2449 *) Fix compile break on some platforms for mod_mime_magic.c
2450 [John K. Sterling <sterling@covalent.net>]
2452 *) Fix merging of AddDefaultCharset directive.
2453 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2455 *) Minor revamp of the rlimit sections of code. We now test
2456 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2457 is now "available" even if the platform doesn't support
2458 the rlimit family (it's just a noop though). [Jim Jagielski]
2460 *) Migrate the pre-selection of which MPM to use for specific
2461 platforms to hints.m4, which contains (or should contain)
2462 all platform specific "hints". [Jim Jagielski]
2464 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2467 *) Add tables with non-string/binary values to APR.
2470 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2473 *) Update PCRE to version 3.2. [Ryan Bloom]
2475 *) Change the way buckets' destroy functions are called so that
2476 they can be more directly used when changing the type of a
2477 bucket in place. [Tony Finch]
2479 *) Add generic support for reference-counting the resources used by
2480 buckets, and alter the HEAP and MMAP buckets to use it. Change
2481 the way buckets are initialised to support changing the type of
2482 buckets in place, and use it when setting aside TRANSIENT buckets.
2483 Change the implementation of TRANSIENT buckets so that it can be
2484 mostly shared with IMMORTAL buckets, which are now implemented.
2487 Changes with Apache 2.0a6
2489 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2491 *) Add a chunking filter to Apache. This brings us one step closer
2492 to removing BUFF. [Ryan Bloom]
2494 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2495 added to the stack is the last filter to be called. [Ryan Bloom]
2497 *) Apache 2.0 has been completely documented using Scandoc. The
2498 docs can be generated by running 'make docs'. [Ryan Bloom]
2500 *) Add filtered I/O to Apache. This is based on bucket brigades,
2501 Currently the buckets still use BUFF under the covers, but that
2502 should change quickly. The only currently written filter is the
2503 core filter which just calls ap_bwrite. [The Apache Group]
2505 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2506 built with thread support. [Jeff Trawick]
2508 *) Abort configuration if --with-layout was specified and there's
2509 no layout definition file. [Ken Coar]
2511 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2513 *) Add support for extension methods for the Allow response header
2514 field, and an API routine for accessing r->allowed and the
2515 list of extension methods in a unified manner. [Ken Coar]
2517 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2518 [Rob Simonson <simo@us.ibm.com>]
2520 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2521 APACHE_XLATE builds. [Jeff Trawick]
2523 *) A configuration file parsing problem was fixed. When the
2524 configuration file started with an IfModule/IfDefine container,
2525 only the last statement in the container would be retained.
2528 Changes with Apache 2.0a5
2530 *) Perchild is serving pages after passing them to different child
2531 processes. There are still a lot of bugs, but this does work. I
2532 have made requests against the same installation of Apache, and had
2533 different servers use different user IDs to serve the responses.
2534 This change moves to using socketpair instead of an AF_UNIX socket.
2537 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2538 It can't seem to pass between child processes yet, but I think we
2539 are closer now than before. This moves us back to using Unix
2540 Domain Sockets. [Ryan Bloom]
2542 *) libapr functions and types renamed with apr_ prefix.
2543 #include "apr_compat.h" for 1.3.x backwards compat
2546 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2547 return the right information on the local socket address.
2548 [Gregory Nicholls <gnicholls@level8.com>]
2550 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2551 [Gregory Nicholls <gnicholls@level8.com>]
2553 *) Add an option to not detach from the controlling terminal without
2554 going into single process mode. This allows for much easier
2555 debugging of the process startup code. [Ryan Bloom]
2557 *) ab: don't use perror() to report the failure of an APR function.
2560 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2561 scoreboard on graceful restarts.
2564 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2565 An invalid ap_proc_t was passed to ap_create_process().
2568 *) Allow modules to register filters. Those filters are still
2569 never called, but this is a step in the right direction.
2570 [Ryan Bloom and Greg Stein]
2572 *) Register the mod_cgid daemon process for cleanup so that it is
2573 killed at termination if it does not die when the parent gets
2574 SIGTERM. This change is to fix occasional problems where the
2575 process stays around. Bugs in similar logic in mod_rewrite and
2576 mod_include were also fixed. [Jeff Trawick]
2578 *) Fix a bug in the time handling. Basically, we were imploding a time
2579 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2580 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2581 uses those two fields to adjust the time value. Because of the HTTP
2582 spec, both of those values can be zero'ed out safely. This fixes
2583 the bug correctly. [Ryan Bloom]
2585 *) Fix a couple of place in the Windows code where the wrong error
2586 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2588 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2590 *) Added the APR_EOL_STR macro for platform dependent differences in
2591 logfiles and other raw text (such as all APR files). Fixes logfiles
2592 not terminated with cr/lf sequences in Win32. [William Rowe]
2594 *) Move all strings functions in APR to src/lib/apr/strings and create
2595 apr_strings.h for the prototypes. [Ryan Bloom]
2597 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2598 to repeat the syscall until we stop getting EINTR. I noticed a
2599 related problem at termination (SIGTERM) on FreeBSD when using
2600 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2601 implementation work properly with child init. Previously, ap_lock()
2602 was essentially a no-op because all children were using different
2603 locks and thus nobody ever blocked. [Jeff Trawick]
2605 *) The htdocs/ tree has been moved out of the CVS source tree into
2606 a separate area for easier development. This has NO EFFECT on
2607 end-users or Apache installations. [Ken Coar]
2609 *) Integrate the mod_dav module for WebDAV protocol handling. This
2610 adds the dav and dav_fs modules, the SDBM library, and additional
2611 XML handling utilities. [Greg Stein]
2613 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2616 *) Update the lib/expat-lite/ library (bring forward changes from
2617 the Apache 1.3 repository). [Greg Stein]
2619 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2620 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2622 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2623 machines where sendfile is detected, but nobody has written ap_sendfile.
2624 [Dave Hill <ddhill@zk3.dec.com>]
2626 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2628 *) ab would start up more connections than needed, then quit when the
2629 desired number were finished. Also fixed a logic error involving
2630 ab keepalives. [Victor J. Orlikowski]
2632 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2633 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2634 timeouts (i.e, if a timeout was specified, the pipe reverted to
2635 a full blocking pipe). Now the behaviour is more in line with
2636 Unix non-blocking pipes.
2639 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2640 cache open file handles along with accept socket reuse enables
2641 Apache 2.0 to serve non-keepalive requests for static files at
2642 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2643 and Apache 2.0 will serve almost 1200 rps on my system).
2646 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2647 supports two config directives, mmapfile (same behavious as
2648 mod_mmap_static) and cachefile. Use the cachefile directive
2649 to cache open file handles. This directive only works on systems
2650 that have implemented the ap_sendfile API. cachefile works today
2651 on Windows NT, but has not been tested on any flavors of Unix.
2654 *) Cleanup the configuration. With the last few changes the
2655 configuration process automatically:
2656 inherits information about how to build from APR. Allowing
2657 APR to inform Apache that it should or should not use -ldl
2659 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2660 based on the threading model
2662 Apache calls APR's configure process before finishing it's
2663 configuration processing, allowing for more information flow
2668 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2669 with non-zero argument makes the socket non-blocking. BeOS and
2670 OS/2 already worked this way. [Jeff Trawick]
2672 *) ap_close() now calls ap_flush() for buffered files, so write
2673 operations work a whole lot better on buffered files.
2676 *) Fix error messages issued from MPMs which explain where to change
2677 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2680 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2681 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2682 now the way that the blocking state of a pipe is manipulated.
2683 ap_block_pipe() is gone. [Jeff Trawick]
2685 *) Correct the problem where the only local host name that the IP stack
2686 can discover are 'undotted' private names. If no fully qualified
2687 domain name can be identified, the default ServerName will be set to
2688 the machine's IP address string. A warning is always provided if the
2689 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2691 *) Repair problems with config file processing which caused segfault
2692 at init when virtual hosts were defined and which caused ServerName to
2693 be ignored when there was no valid DNS setup. [Jeff Trawick]
2695 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2697 *) Add ap_sendfile implementation for AIX
2698 [Victor J. Orlikowski]
2700 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2701 apr_network_io.h, and apr_thread_proc.h.
2702 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2704 *) Bring the allocation and pool debugging code back into a working
2705 state. This will need to be tested as so far it's only been used on
2708 *) Change configuration command setup to be properly typesafe when in
2709 maintainer mode. Note that this requires a compiler that can initialise
2710 unions. [Ben Laurie]
2712 *) Turn on buffering for config file reads. Part of this was to
2713 repair buffered I/O support in Unix and implement buffered
2714 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2716 *) Win32: Fix problem where UTC offset was not being set correctly
2717 in the access log. Problem reported on news group by Jerry Baker.
2720 *) Fix segfault when reporting this type of syntax error:
2721 "</container> without matching <container> section", where
2722 container is VirtualHost or Directory or whatever.
2725 *) Prevent the source code for CGIs from being revealed when using
2726 mod_vhost_alias and the CGI directory is under the document root
2727 and a user makes a request like http://www.example.com//cgi-bin/cgi
2728 as reported in <news:960999105.344321@ernani.logica.co.uk>
2731 *) Add support for the new Beos NetwOrking Environment (BONE)
2734 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2735 final input char is incomplete; ap_bwrite_xlate() now handles
2736 incomplete final input chars. [Jeff Trawick]
2738 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2739 that a bhalfduplex call occurs before logging or else DNS and
2740 such can delay the last packet of the response. [Dean Gaudet]
2742 *) Some syscall reduction in APR on unix -- don't seek when setting
2743 up an mmap; and don't fcntl() more than once per socket.
2746 *) When mod_cgid is started as root, the cgi daemon now switches
2747 to the configured User/Group (like other httpd processes)
2748 instead of continuing as root. [Jeff Trawick]
2750 *) The prefork MPM now uses an APR lock for the accept() mutex.
2751 It has not been getting a lock at all recently. httpd -V now
2752 displays APR's selection of the lock mechanism instead of the
2753 symbols previously respected by prefork. [Jeff Trawick]
2755 *) Change the mmap() feature test to check only for existence.
2756 The previous check required features not used by Apache.
2759 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2760 sometimes mangled. The len parm to accept() was not
2761 initialized, leading sometimes to an endless loop of failed
2762 accept() calls on OS/390 and anywhere else that failed the call
2763 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2764 instead of declaring it ourselves to fix a compilation problem
2765 on Solaris. [Jeff Trawick]
2767 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2769 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2771 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2773 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2774 initialization if ALLOC_DEBUG is defined; no known symptom
2775 otherwise. [Jeff Trawick]
2777 *) Fix typo in configure script when checking for mod_so. bash
2778 doesn't seem to have a problem but /bin/sh on Solaris does.
2779 Symptom: "./configure: test: unknown operator =="
2782 *) Rebind the Win32 NT and 9x services control into the MPM.
2783 All console, WinNT SCM and Win9x pseudo-service control code is
2784 now wrapped within the WinNT MPM.
2787 *) Make a copy of getenv("PATH") before storing for later use. Some
2788 getenv() implementations use the same storage for successive calls.
2789 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2791 *) Server Tokens work in 2.0 again. This also propogates the change
2792 to allow just the product name in the server string using
2796 Changes with Apache 2.0a4
2798 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2799 won't need to call it. [Greg Ames, Jeff Trawick]
2801 *) Move pre_config hook call to between configuration read and config
2802 tree walk. This allows all modules to implement pre_config hooks
2803 and know that they will be called at an appropriate time.
2806 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2809 *) Add pre-config hooks back to all modules.
2812 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2813 ContentDigest enabled and we can't/don't mmap the file.
2816 *) We now report the correct line number for syntax errors in config
2817 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2819 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2820 related bugs, and changed shmem/locking to use apr API. Shared-mem
2821 is currently disabled, however, because of problems with graceful
2822 restarts. [Ronald Tschalär]
2824 *) Fix corruption of IFS variable in --with-module= handling.
2825 Depending on the user's shell or customization thereof, there
2826 would be errors generating ap_config_auto.h later in the configure
2827 procedure. [Jeff Trawick]
2829 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2830 isn't used (as in 1.3), except that on Unix it is now logged via
2831 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2832 to the error log. [Greg Ames, Jeff Trawick]
2834 *) Add '-D' argument processing for run time configuration defines.
2837 *) Organize http_main.c as independent code, such that no code or
2838 global data is exported from it. WIN32 will dynamically link it
2839 to the server core, so this will prevent mutual dependency.
2842 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2843 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2846 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2847 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2849 *) Add mod_charset_lite for configuring character set translation.
2852 *) Add '-n' option to htpasswd to make it print its user:pw record
2853 on stdout rather than having to frob a text file. [Ken Coar]
2855 *) Fix saferead. Basically, we flush the output buffer if a read on the
2859 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2860 a conversion is single-byte only. [Jeff Trawick]
2862 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2863 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2866 *) Fix some minor errors where pid was being manipulated as an int
2867 instead of the portable pid_t. [Roy Fielding]
2869 *) Fix some error log prints that were printing the pointer to a
2870 structure rather than the pid within the structure.
2871 [Jeff Trawick, Roy Fielding]
2873 *) ab: Fix a command-line processing bug; track bad headers in
2874 err_response; support reading headers up to 2K.
2875 [Ask Bjoern Hansen <ask@valueclick.com>]
2877 *) Fix ap_resolve_env() so that it handles new function added in a prior
2878 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2879 config file.") as well as the constructs used by mod_rewrite.
2880 [Paul Reder <rederpj@raleigh.ibm.com>]
2882 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2884 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2885 APR to perform translation, instead of accessing the hard-coded tables
2886 in 1.3's ebcdic.c. [Jeff Trawick]
2888 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2891 *) Add the ability to hook into the config file reading phase. Basically
2892 if a directive is specified EXEC_ON_READ, then when that directive is
2893 read from the config file, the assocaited function is executed. This
2894 should only be used for those directives that must muck with HOW the
2895 server INTERPRETS the config. This should not be used for directives
2896 that re-order or replace items in the config tree. Those changes should
2897 be made in the pre-config step.
2900 *) Add mod_example to the build system.
2903 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2904 byte character sets. [Jeff Trawick]
2906 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2907 Kraemer and Oliver Reh originally according to the change log).
2910 *) Fix a couple of problems in RFC1413 support (controlled by the
2911 IdentityCheck directive). Apache did not build the request string
2912 properly and more importantly Apache would loop forever if the
2913 would-be ident server dropped the connection before sending a
2914 properly terminated response. [Jeff Trawick]
2916 *) apxs works in 2.0.
2919 *) Reliable piped logs work in 2.0.
2922 *) Introduce a hash table implementation into APR to be used for
2923 replacing tables and other random data structures in Apache.
2926 *) Add some more error reporting to htpasswd in the case of problems
2927 generating or accessing the temporary file. Also, pass in a
2928 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2929 is defined). [Ken Coar]
2931 *) Configure creates config.nice now containing your configure
2932 options. Syntax: ./config.nice [--more-options]
2935 *) Fix various return code problems in APR on Win32. For most of
2936 these, APR was returning APR_EEXIST instead of GetLastError()/
2937 WSAGetLastError(). [Jeff Trawick]
2939 *) Make piped logs work again in version 2.0
2942 *) Add VPATH support to UNIX build system of Apache and APR.
2945 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2949 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2950 Patch submitted to author.
2953 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2954 /sbin in PATH on FreeBSD (all submitted to rse previously)
2957 *) Fix building Pthread-based MPMs on OpenBSD
2958 [Sascha Schumann] PR#26
2960 *) Fix ap_readdir() problem on systems where d_name[] field in
2961 struct dirent is declared with only one byte. (This problem only
2962 affected multithreaded builds.) This caused a segfault during
2963 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2964 least). [Jeff Trawick]
2966 *) Fix some make-portability problems on at least Tru64, Irix
2968 [Sascha Schumann] PR#18, PR#39
2970 *) Add ap_sigwait() to support old-style sigwait() on systems
2971 like OS/390 and UnixWare.
2974 *) Add POSIX-thread flags for more platforms.
2977 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2978 (on Unix, at least) to handle resolver errors. Fix a bug in
2979 the definition of APR_ENOMEM so that ap_strerror() can spit
2980 out the correct error message for it.
2983 Changes with Apache 2.0a3
2985 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2988 *) API: *HOOK* macros now have an AP_ prefix
2991 *) Win32: Eliminate redundant calls to initialize winsock.
2992 [Tim Costello <timcostello@ozemail.com.au>]
2994 *) Fix bugs initializing ungetchar for pipes.
2995 [Chia-liang Kao <clkao@CirX.ORG>]
2997 *) The ab program in the src/support directory is now portable using
3001 *) Support directory is being compiled when the server is built
3004 *) The configure option --with-program-name has been added to allow
3005 developers to rename the executable at configure time. This also
3006 changes the name of the config files to match the executable's name.
3009 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
3010 containing version numbers. [Martin Pool]
3012 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
3013 Unix; access_log and error_log now created with these perms; non-
3014 Unix is unaffected [Jeff Trawick]
3016 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
3017 Replaced more magic numbers with MD5_DIGESTSIZE.
3018 [William Rowe, Roy Fielding]
3020 *) Win32: Get mod_auth_digest compiling and added to the Windows
3021 build environment. Not tested and I'd be suprised if it
3022 actually works. [Bill Stoddard]
3024 *) Revamp the Win32 make environment. Makefiles have been removed and
3025 Apache.dsw created to bring together all the pieces. Create new file
3026 os/win32/BaseAddr.ref to define module base addresses (to prevent
3027 dll relocation at start-up).
3028 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
3030 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
3031 of the \015, \012, and \015\012 constants with macros.
3032 [Greg Ames <gregames@us.ibm.com>]
3034 *) Add ap_xlate_open() et al for translation of text between different
3035 character sets. The initial implementation requires iconv().
3038 *) More FAQs and answers from comp.infosystems.www.servers.unix.
3039 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3041 *) CGI output is being timed out now.
3044 *) Fix the problem with dieing quietly. dupfile now takes a pool which
3045 is used by the new apr file. There is no reason to create a new file
3046 with the same lifetime as the original file.
3049 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
3050 module base addresses. This will help shooting seg faults
3051 in the field. [William Rowe <wrowe@lnd.com>]
3053 *) Update Apache on Windows documentation. Add new document
3054 describing how to compile Apache on Windows.
3055 [William Rowe <wrowe@lnd.com>]
3057 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
3058 microseconds instead of seconds. Some storage leaks and other
3059 minor bugs in related code were fixed. [Jeff Trawick]
3061 *) Win32: First cut at getting mod_isapi working under 2.0
3062 [William Rowe <wrowe@lnd.com>]
3064 *) First stab at getting mod_auth_digest working under 2.0
3065 quick change summary:
3066 - moved the random byte generation (ap_generate_random_bytes) into APR
3067 - now uses ap_time_t
3068 - compiles and runs on linux
3070 [Brian Martin <bmartin@penguincomputing.com>]
3072 *) Win32: Move the space stripping of physical service names
3073 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
3074 unresolved symbol. Add dependency checking to the
3075 CreateService call to ensure TCPIP and AFP (winsock) is started
3077 [William Rowe <wrowe@lnd.com>]
3079 *) Win32: Add code to perform latebinding on functions that may
3080 not exist on all levels of Windows where Apache runs. This
3081 is needed to allow Apache to start-up on Win95/98. All calls
3082 to non portable functions should be protected with
3083 ap_oslevel checks to prevent runtime segfaults.
3084 [William Rowe <wrowe@lnd.com>]
3086 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
3088 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
3090 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
3091 This addresses PR 1623. Still need to address timing out runaway
3092 CGI scripts. [Bill Stoddard]
3094 *) Win32: Make ap_stat Windows 95/98 friendly
3095 [William Rowe <wrowe@lnd.com>]
3097 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
3098 always fail. Need to initialise the dwOSVersionInfoSize member of the
3099 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
3102 The patch also enhances ap_get_oslevel (and the associated enum) to
3103 handle selected service packs for NT4, and adds recognition for
3104 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
3105 we can use ReadFileScatter and WriteFileGather in readwrite.c.
3106 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
3108 *) Get mod_rewrite building and running, and mod_status building for Win NT
3109 [Allan Edwards <ake@raleigh.ibm.com>]
3111 *) Patch to port mod_auth_db to the 2.0 api and also to support
3112 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
3113 2.7.7. It should work with version 1 as well but I haven't tested it.
3114 [Brian Martin <bmartin@penguincomputing.com>]
3116 *) Get APR DSO code working under Windows. Includes cross platform
3118 [Tim.Costello@BTFinancialgroup.com]
3120 *) Fix some of the Windows APR time functions.
3123 *) FAQ changes related to tidying up historical documents on the web site.
3124 [Joshua Slive <slive@finance.commerce.ubc.ca>]
3126 *) Move Windows DSO code into APR.
3129 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
3130 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
3131 at build time. At this point, the server will not compile on Windows because
3132 of the recent DSO commits. Fixing those next.
3133 [Bill Rowe & Bill Stoddard]
3135 *) Added error checking for file I/O APR routines.
3136 [Jon Travis <jtravis@covalent.net>]
3138 *) APR: Don't use the values of resolver error codes for the
3139 corresponding APR error codes. On Unix and Win32, return the
3140 proper APR error code after a resolver error. [Jeff Trawick]
3142 Changes with Apache 2.0a2
3144 *) Renamed the executable back to httpd on all platforms other
3148 *) Allow BeOS to survive restarts, log properly and a few
3149 small things it had problems with due to the way it setup
3150 users and groups. [David Reid]
3152 *) Get mod_rewrite working with APR locks
3153 [Paul Reder <rederpj@raleigh.ibm.com>]
3155 *) Actually remove the sempahore when the lock cleanup routine
3156 is called on BeOS. [David Reid]
3158 *) Clear hook registrations between reads of the config file.
3159 When DSOs are unloaded and re-loaded the old hook pointers may
3160 no longer be valid. This fix eliminates potential segfaults.
3161 [Allan Edwards <ake@raleigh.ibm.com>]
3163 *) Fix a problem with Sigfunc not being defined or bypassed
3164 if sigaction() wasn't found. [Jim Jagielski]
3166 *) Fix the locking mechanism on BSD variants. They now use fcntl
3167 locks. This allows the server to start and serve pages.
3170 *) First cut at getting the Win32 installer to work
3171 [William Rowe <wrowe@lnd.com>]
3173 *) Get htpasswd compiling under Windows
3174 [William Rowe <wrowe@lnd.com>]
3176 *) Change the log message for a bind() failure to show the
3177 interface and port number. [Jeff Trawick]
3179 *) Import the documentation from 1.3.12 and bring parts of it
3180 up-to-date with respect to the changes that have occurred
3184 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
3185 now logged correctly on BeOS.
3188 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
3189 Makefile.win includes the same user interface as the old
3191 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
3193 *) Win32 exec now uses COMSPEC environment string for command
3194 shell path resolution.
3195 [William Rowe <wrowe@lnd.com>] PR#3715
3197 *) Win32: ap_connect() was not returning correct error condition
3199 [Allen Prescott <allen@clanprescott.com>]
3201 *) Win32: ap_open() was broken on Win9x because an NT-specific
3202 flag was passed to CreateFile. ap_puts() added an unnecessary
3204 [Jeff Trawick <trawick@us.ibm.com>]
3206 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
3207 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
3208 confusing ee/et name and made all extensions language/dialect
3209 rather than country reflecting. Changed example files to
3210 explicit reflect the ISO charset and added a few common
3211 ones to the example config [dirkx]
3213 *) Extend external module capability. To use this, you call
3214 configure with --with-module=path/to/mod1,path/to/mod2,etc.
3217 *) Backported the various "default charset" fixes from 1.3.12,
3218 including the AddDefaultCharset directive. [Jim Jagielski]
3220 *) Added the capability to do ${ENVVAR} constructs in the
3221 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
3222 it does this on a line by line basis; i.e. if the envvar
3223 expands to something with spaces you have to protect it
3224 by adding quotes around it (Unless of course you expect it
3225 to contains more than one argument. Alternatively you
3226 can compile it on a per token basis; which is what people
3227 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
3228 hampers fancier hacks.
3229 [Dirk-Willem van Gulik]
3231 *) Changed the 'ErrorDocument' syntax in that it NO longer
3232 supports the asymetric
3234 ErrorDocument 301 "Some message
3236 Note the opening " quote, without a closing quote. It now
3237 has either the following syntaxes
3239 ErrorDocument XXX /local/uri
3240 ErrorDocument XXX http://valid/url
3241 ErrorDocument XXX "Some Message"
3243 The recognition heuristic is: if it has a space it
3244 is a message. If it has no spaces and starts with a /
3245 or is a valid URL then treat it that way. Otherwise it
3246 is assumed to be a message.
3248 This breaks backward compatibility but makes live a hell
3249 of a lot easier for GUI's and config file parsers.
3250 [Dirk-Willem van Gulik]
3252 *) Changed 'CacheNegotiatedDocs' from its present/not-present
3253 syntax into a 'on' or 'off' syntax. As it currently is the
3254 only non nesting token which uses NO_ARGS and thus is an
3255 absolute pain for any config interface automation. This
3256 breaks backward compatibility. [Dirk-Willem van Gulik]
3258 *) Add ability to add external modules to the build process. This is
3259 done with --with-module=/path/to/module. Modules can only be added
3260 as static modules at this point.
3263 Changes with Apache 2.0a1
3265 *) Fix FreeBSD 3.3 core dump.
3266 Basically, ap_initialize() needs to get called before
3267 create_process(), since create_process() passes op_on structure
3268 to semop() to get a lock, but op_on isn't initialized until
3269 ap_initialize() calls setup_lock(). Here is a slight
3270 rearrangement to main() which calls ap_initialize() earlier...
3271 [Jeff Trawick <trawick@us.ibm.com>]
3273 *) Enable Apache to use sendfile/TransmitFile API
3274 [Bill Stoddard, David Reid, Paul Reder]
3276 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
3280 *) Make file I/O and network I/O writev/sendv APIs consistent.
3281 Eliminate use of ap_iovec_t and use Posix struct iovec.
3282 Use seperate variable on ap_writev to set the number of iovecs
3283 passed in and number of bytes written.
3286 *) Adapt file iol to use APR functions. Replaced ap_open_file()
3287 with ap_create_file_iol(). ap_create_file_iol() requires that
3288 the file be opened prior to the call using ap_open().
3291 *) Port mod_include and mod_cgi to 2.0
3292 [Paul Reder, Bill Stoddard]
3294 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
3295 bytes_read/bytes_written is always valid (never -1). Plus
3296 some fixes to buff.c to correct problems introduced by the
3297 errno => ap_status_t changes a while back. Plus a fix to
3298 chunked encoding introduced right at the beginning of 2.0.
3301 *) Revamped UNIX build system to use autoconf and libtool.
3302 [Manoj Kasichainula, Sascha Schumann]
3304 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
3306 *) More rigorous checking of Host: headers to fix security problems
3307 with mass name-based virtual hosting (whether using mod_rewrite
3308 or mod_vhost_alias).
3309 [Ben Hyde, Tony Finch]
3311 *) Add back support for UseCanonicalName in <Directory> containers.
3312 [Manoj Kasichainula]
3314 *) Added APLOG_STARTUP log type. This allows us to write an error
3315 message without any of the date and time information. As a part
3316 of this change, I also removed all of the calls to fprintf(stderr
3317 and replaced them with calls to ap_log_error using APLOG_STARTUP
3318 writing to stderr is no longer portable, because we don't direct
3319 stderr to the error log on all platforms.
3322 *) Convert error logging functions to take errno as an argument.
3323 This makes our error logs more portable, because some Windows API's
3324 don't set errno. This change allows us to still output a valid
3325 message on all of our platforms.
3328 *) mod_mime_magic runs in 2.0-dev now.
3329 [Paul Reder <rederpj@raleigh.ibm.com>]
3331 *) sendfile has been added to APR.
3332 [John Zedlewski <zedlwski@Princeton.EDU>]
3334 *) buff.c has been converted to no longer use errno.
3335 [Manoj Kasichainula]
3337 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3338 interface adaption to APR functions did it. [Martin Kraemer]
3340 *) Support DSOs properly on 32-bit HP-UX 11.0
3341 [Dilip Khandekar <dilip@cup.hp.com>]
3343 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3344 [Ralf S. Engelschall]
3346 *) Cleaned APR build environment integration and bootstrap APR
3347 automatically for developers from src/Configure.
3348 [Ralf S. Engelschall]
3350 *) Fixed building of src/support/htpasswd.c
3351 [Ralf S. Engelschall]
3353 *) When generating the Location: header, mod_speling forgot
3354 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3357 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3359 *) Change all pools to APR contexts. This is the first step to
3360 incorporating APR into Apache. [Ryan Bloom]
3362 *) Move "handler not found" warning message to below the check
3363 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3364 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3366 *) Support line-continuation feature in config.option file and
3367 allow the loading of multiple option sections at once via
3368 ``--with-option=<section1>,<section2>,...''
3369 [Ralf S. Engelschall]
3371 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3373 Changes with Apache MPM
3375 *) Use asynchronous AcceptEx() and a completion port to accept and
3376 dispatch connections to threads in Windows NT/2000.
3379 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3382 *) Implement the APACI --with-option facility
3383 (per default used the config.option file).
3384 [Ralf S. Engelschall]
3386 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3388 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3389 Replace pre_connection module call with a register_hook call and
3390 implement pre_connection as a hook. The intent is that these hooks will
3391 be extended to allow Apache to be multi-protocol, and also to allow the
3392 calling order to be specified on a per-hook/per-module basis.
3395 *) Implement mpm_* methods as "modules". Each method gets its own
3396 subdir in src/modules (eg: src/modules/prefork). Selection
3397 of method uses Rule MPM_METHOD. [Jim Jagielski]
3399 *) Port the hybrid server from the apache-apr repository as
3400 mpm_mpmt_pthread. [Manoj Kasichainula]
3402 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3403 amongst the unix MPMs.
3405 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3406 signal handling for the new world order. [Dean Gaudet]
3408 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3409 of alloc.c for now. [Dean Gaudet]
3411 *) Handle partial large writes correctly. [Ben Laurie]
3413 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3414 based on IP/port. [Ben Laurie]
3416 *) Port a bunch of modules to the new module structure.
3417 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3419 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3421 *) Basic restructuring to introduce the MPM concept; includes various
3422 changes to the module API... better described by
3423 docs/initial_blurb.txt. [Dean Gaudet]
3425 Changes with Apache pthreads
3427 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3428 buff operations (generally over a network).
3429 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3431 *) Created http_accept abstraction. Added 4 new functions (not exported):
3432 init_accept(), begin_accepting_requests(), get_request(),
3433 stop_accepting_requests() [Bill Stoddard]
3435 *) Fix to ap_rprintf call that allows mod_info to work properly.
3436 [James Morris <jmorris@intercode.com.au>]
3438 *) user and ap_auth_type fields were moved from connection_rec to
3439 request_rec. [Ryan Bloom]
3441 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3442 needed in a threaded server.
3444 *) Initial pthread implementation from from Dean's apache-nspr code.
3445 [Bill Stoddard, Ryan Bloom]
3448 Changes with Apache 1.3.9
3450 *) Remove bogus error message when a redirect doesn't set Location.
3451 Instead, use an empty string to avoid coredump if the error message
3452 was supposed to include a location. [Roy Fielding]
3454 *) Don't allow configure to include mod_auth_digest unless it is
3455 explicitly requested, even if the user asked for all modules.
3458 *) Translate module names to dll names for OS/2 so that they are no more
3459 than 8 characters long and have an extension of "dll" instead of "so".
3462 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3463 Fix test-compile check to check for randbyte instead of trand32.
3464 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3465 and tweak to make Amaya happier. [Ronald Tschalär]
3467 *) Ensure that the installed expat include files are world readable,
3468 just like the other header files. [Martin Kraemer]
3470 *) Fixed generated AddModule adjustments in APACI's `configure' script
3471 in order to allow (new) modules like mod_vhost_alias to be handled
3472 correctly (which was touched by the adjustments for mod_alias).
3473 [Ralf S. Engelschall]
3475 *) For binary builds, add -R flag to apachectl to work around the lack of
3476 an absolute path to the ./libexec directory where the libhttp.ep file
3477 is needed for SHARED_CORE architectures. [Randy Terbush]
3479 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3480 problem observed by some Win95/98 users where they get CGI script
3481 output sent to the console. [Bill Stoddard]
3483 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3484 routines are now called ap_base64* and are 'plain' (i.e., no
3485 pool access or anything clever). Inside util.c the routines acting
3486 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3487 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3488 now but deprecated. [dirkx]
3490 *) Clean up the base64 and SHA1 additions and make sure they are
3491 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3492 files. [Roy Fielding]
3494 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3495 checking. Allow compiling on VS 6.0. [Randy Terbush]
3497 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3499 *) Use TestCompile to search for the truerand library (rather than blindly
3500 assuming its existence). If it is not found, complain (but do not
3501 exit - yet). [Martin Kraemer]
3503 *) We forgot to add the new exported function names to
3504 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3506 *) Add description of -T command-line option to usage().
3507 [Ralf S. Engelschall]
3509 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3510 searched only AFTER libap has been searched, because libap needs
3511 some symbols from libos. [Martin Kraemer]
3513 *) Fix conflict with original mod_digest related to the symbol of the
3514 module dispatch list (which has to be unique for DSO and follow the
3515 usual conventions for the installation procedure).
3516 [Ralf S. Engelschall]
3518 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3519 for other platforms as well. [Martin Kraemer]
3521 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3522 types by AP_LONG and replace reference to renamed variable 'ubuf'
3523 by 'buffer'. [Martin Kraemer]
3525 Changes with Apache 1.3.8 [not released]
3527 *) Flush the output buffer immediately after sending an error or redirect
3528 response, since the result may be needed by the client to abort a
3529 long data transfer or restart a series of pipelined requests.
3530 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3532 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3533 [Ian Turner <iant@sequent.com>] PR#4735
3535 *) Local struct mmap in http_core.c conflicted with system structure
3536 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3538 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3539 [Ronald Tschalär <ronald@innovation.ch>]
3541 *) Fix a memory leak where the module counts were getting messed
3542 up across restarts. [David Harris <dharris@drh.net>]
3544 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3545 properly in mod_access.
3546 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3548 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3549 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3551 *) PORT: Support for compaq/tandem/com.
3552 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3554 *) Added SHA1 password encryption support to easy migration from
3555 Netscape servers. See support/SHA1 for more information.
3556 Caused the separation of ap_md5.c into md5, sha1 and a general
3557 ap_checkpass.c with just a validate_passwd routine. Added a
3558 couple of flags to support/htpasswd. Some reuse of the to64()
3559 function; hence renamed to ap_to64().
3560 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3562 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3563 with ASCII/EBCDIC conversions in "ident" query.
3564 [David McCreedy <McCreedy@us.ibm.com>]
3566 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3567 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3568 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3570 *) Fix SIGSEGV on some systems because the Vary fix below included
3571 a call to table_do with a variable argument list that was not
3572 NULL terminated. Replaced with better implementation. [Roy Fielding]
3574 Changes with Apache 1.3.7 [not released]
3576 *) The "Vary" response header field is now sanitised right before
3577 the header is sent back to the client. Multiple "Vary" fields
3578 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3579 "Vary: host, negotiate, host, accept-language") are reduced to
3580 single instances. This is a better solution than the force-no-vary
3581 one (which is still valid for clients that can't cope with Vary
3582 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3584 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3586 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3587 least on Linux and FreeBSD for now.
3590 *) Win32: More apache -k restart work. Restarts are now honored
3591 immediately and connections in the listen queue are -not- lost.
3592 This is made possible by the use of the WSADuplicateSocket()
3593 call. The listeners are opened in the parent, duplicated, then
3594 the duplicates are passed to the child. The original listen sockets
3595 are not closed by the parent across a restart, thus the listen queue
3597 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3599 *) Fix handling of case when a client has sent "Expect: 100-continue"
3600 and we are going to respond with an error, but get stuck waiting to
3601 discard the body in the pointless hope of preserving the connection.
3602 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3604 *) Fix 'configure' to work correctly with SysV-based versions of
3605 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3607 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3608 built-in values. Add "-e" option which works like -i but doesn't
3609 install the DSO; useful for editing httpd.conf with apxs. Fix
3610 editing code so that multiple invocations of apxs -a will not
3611 create duplicate LoadModule/AddModule entries; apxs can now be
3612 used to re- enable/disable a module. [Wilfredo Sanchez]
3614 *) Win32: Update the server to use Winsock 2. Specifically, link with
3615 ws2_32.lib rather than wsock32.lib. This gives us access to
3616 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3617 Win 95 users may need to update their TCP/IP stack to pick up
3618 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3619 [Bill Stoddard stoddard@raleigh.ibm.com]
3621 *) Win32: Redirect CGI script stderr (script debug info) into the
3622 error.log when CGI scripts fail. This makes Apache on Win32
3623 behave more like Unix.
3624 [Bill Stoddard stoddard@raleigh.ibm.com]
3626 *) Fixed `httpd' usage display: -D was missing.
3627 [Ralf S. Engelschall] PR#4614
3629 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3630 [Ralf S. Engelschall] PR#4561, PR#4562
3632 *) OS/2: Fix problem with accept lock semaphores where server would die with
3633 "OS2SEM: Error 105 getting accept lock. Exiting!"
3634 [Brian Havard] PR#4505
3636 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3637 [Randy Terbush <randy@covalent.net>]
3639 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3640 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3642 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3643 command potentially _is_ GCC. [Ralf S. Engelschall]
3645 *) Fix apxs build issues on AIX
3646 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3648 *) DocumentRoot Checking: Under previous versions, when Apache
3649 first started up, it used to do a stat of each DocumentRoot to
3650 see if it existed and was a directory. If not, then an error
3651 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3652 does not exist, you will get error messages in error_log. If
3653 the '-t' command line option is used (to check the configuration)
3654 the check of DocumentRoot IS performed. An additional command
3655 line option, '-T', has been added if you want to avoid the
3656 DocumentRoot check even when checking the configuration.
3659 *) Win32: The query switch "apache -S" didn't exit after showing the
3660 vhost settings. That was inconsistent with the other query functions.
3661 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3663 *) Win32: Changed behaviour of apache -k restart.
3664 Previously, the server would drain all connections in the stack's
3665 listen queue before honoring the restart. On a busy server, this
3666 could take hours. Now, a restart is honored almost immediately.
3667 All connections in Apache's queues are handled but connections in
3668 the stack's listen queue are discarded. Restart triggered by
3669 MaxRequestPerChild is unchanged.
3670 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3672 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3673 the accept loop. Good for a 5% performance boost. Cleaned up
3674 parent/child process management code.
3675 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3677 *) Added ceiling on file size for memory mapped files.
3678 [John Giannandrea <jg@meer.net>] PR#4122
3680 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3681 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3682 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3684 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3685 use this at least for Expat. [Ralf S. Engelschall]
3687 *) Allow .module files to specify libraries with Lib:.
3690 *) Allow SetEnvIf[NoCase] to test environment variables as well
3691 as header fields and request attributes. [Ken Coar]
3693 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3694 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3696 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3697 never accepted into any standard, and it opens up certain DoS
3698 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3700 *) TestCompile updated. We can now run programs and output the
3701 results during the Configure process. [ Jim Jagielski]
3703 *) The source is now quad (long long) aware as needed. Specifically,
3704 the Configure process determines the correct size of off_t and
3705 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3706 provides for the 'q' format qualifier (if quads are not available,
3707 'q' is silently "demoted" to long). [Jim Jagielski]
3709 *) When the username or password fed to htpasswd is too long, include the
3710 size limit in the error message. Also report illegal characters
3711 (currently only ':') in the username. Add the size restrictions
3712 to the man page. [Ken Coar]
3714 *) Fixed the configure --without-support option so it doesn't result in
3715 an infinite loop. [Marc Slemko]
3717 *) Piped error logs could cause a segfault if an error occured
3718 during configuration after a restart.
3719 [Aidan Cully <aidan@panix.com>] PR#4456
3721 *) If a "Location" field was stored in r->err_headers_out rather
3722 than r->headers_out, redirect processing wouldn't find it and
3723 the server would core dump on ap_escape_html(NULL). Check both
3724 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3725 if Location isn't set. [Doug MacEachern, Ken Coar]
3727 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3728 of the Expat 1.0.2 distribution. [Greg Stein]
3730 *) Replace regexec() calls with calls to a new API stub function
3731 ap_regexec(). This solves problems with DSO modules which use the regex
3732 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3734 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3735 environment variables can be set according to the protocol version
3736 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3738 *) Add DSO support for OpenStep (Mach 4.2) platform.
3739 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3741 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3742 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3744 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3745 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3747 *) Better DSO flags recognition on NetBSD platforms using ELF.
3748 [Todd Vierling <tv@pobox.com>] PR#4310
3750 *) Always log months in english format for %t in mod_log_config.
3751 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3753 *) Support for server-parsed and multiview-determined ReadmeName and
3754 HeaderName files in mod_autoindex. Removed the restriction on
3755 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3756 routines will deal with the access issues. (It's now possible to
3757 have {site|group|project|customer|...} wide readmes and headers.)
3758 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3761 *) When stat() fails, don't assume anything about the contents of
3762 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3764 *) It's OK for a semop to return EINTR, just loop around and try
3765 again. [Dean Gaudet]
3767 *) Fix configuration engine re-entrant hangups, which solve a
3768 handful of problems seen with mod_perl <Perl> configuration sections
3769 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3771 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3772 by default when building with APACI; allow for platform-specific
3773 variable defaults in configure. [Wilfredo Sanchez]
3775 *) Do setgid() before initgroups() in http_main; some platforms
3776 zap the grouplist when setgid() is called. This was fixed in
3777 suexec earlier, but the main httpd code missed the change.
3778 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3780 *) Add recognition of .tgz as a gzipped tarchive.

3783 *) mod_include's fsize/flastmod should allow only relative paths, just
3784 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3786 *) OS/2: Add support for building loadable modules using DLLs.
3789 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3792 *) Fix minor but annoying bug with the test for Configuration.tmpl
3793 being newer than Configuration so that it is less likely to fail
3794 when using APACI and shadow sources. [Wilfredo Sanchez]
3796 *) PORT: Add initial support for Mac OS (versions 10.0 and
3797 greater). Use Mac OS X Server layout for now. Clean up dyld code
3798 in unix/os.c, and don't install the dyld error handlers, which
3799 are no longer needed in Mac OS. [Wilfredo Sanchez]
3801 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3802 locations to appropriate ones for user-built (as opposed to
3803 system) installs. [Wilfredo Sanchez]
3805 *) Modify mod_autoindex's handling of AddDescription so that the
3806 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3808 *) Add functionality to the install-bindist.sh script created by
3809 binbuild.sh to use tar when copying distribution files to the
3810 serverroot. This allows upgrading an existing installation
3811 without nesting the new distribution in the old.
3813 install-bindist.sh now detects the local perl5 path to install
3814 apxs and dbmmanage with proper path to perl interpreter.
3816 Add an install-binsupport target which copies the source files
3817 for apxs and dbmmanage to bindist to allow these scripts to
3818 be properly installed relative to the destination serverroot.
3819 [Randy Terbush, Covalent Technologies, randy@covalent.net]

3833 *) Force the LANG envariable to the known state of "C" so that we
3834 have assurance about how string manipulators (e.g., tr) will
3835 function. [Ken Coar] PR#1630
3837 *) Add a directive to allow customising of the tracking cookie name.
3838 [Ken Coar] PR#2921, 4303
3840 *) Add "force-no-vary" envariable to allow servers to work around
3841 clients that choke on "Vary" fields in the response header.
3842 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
3844 *) Fixed a bug in mod_dir that causes a child process will infinitely
3845 recurse when it attemps to handle a request for a directory wnd the
3846 value of the DirectoryIndex directive is a single dot. Also likely
3847 to happen for anyother values of DirectoryIndex that will map back

3981 *) Correct the signed/unsigned character handling for the MD5 routines;
3982 mismatches were causing compilation problems with gcc -pedantic and
3983 in the TPF cross-compilation. [Ken Coar]
3985 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3986 a roughly 5 fold speed up. [Brian Havard]
3988 *) proxy ftp: instead of using the hardwired string "text/plain" as
3989 a fallback type for files served by the ftp proxy, use the
3990 ap_default_type() function to determine the configured type.
3991 This allows for special configurations like
3992 <Directory proxy:ftp://some.host>
3993 DefaultType gargle/blurb
3995 Additionally, add the Content-Encoding: header to FTP proxy replies
3996 when the encoding is defined (by the AddEncoding directive).
3997 Because it was missing, it was almost impossible to browse compressed
3998 files using the FTP proxy (works now perfectly in Communicator).
3999 The ftp proxy now also returns the Date: and Server: header lines (if not
4000 much else... This code is "somewhat" broken) like normal requests do.
4003 *) Be more smart in APACI's configure script when determining the UID/GID
4004 for User/Group directives and use the determined UID/GID to initialize
4005 the permissions on the proxycachedir.
4006 [Dirk-Willem van Gulik, Ralf S. Engelschall]
4008 *) Changed the forking-prior-to-cleanup in the proxy module to first
4009 check wether it actually needs to collect garbage. This reduces
4010 the number of fork()s from one/request to just the odd one an hour.
4011 [Dirk-Willem van Gulik]
4013 *) Added proxy, auth and header support to src/support/ab.c. Added a
4014 README file to src/support/
4015 [Dirk-Willem van Gulik]
4017 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
4018 [Ralf S. Engelschall] PR#4050
4020 *) Add support for DSO module compilation on BSD/OS 3.x.
4021 [Randy Terbush, Covalent Technologies]
4023 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
4024 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
4025 option) were substituted with $(TARGET).conf, etc. Same for other strings
4026 with dots where the dot wasn't matched as plain text.
4027 [Ralf S. Engelschall]
4029 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
4031 *) Fix verbose output of APACI configure (option -v)
4032 [Martin Kraemer, Ralf S. Engelschall]
4034 Changes with Apache 1.3.6
4036 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
4038 Changes with Apache 1.3.5 [not released]
4040 *) M_INVALID needed a value within the scope of METHODS so that unknown
4041 methods can be access controlled. [Roy Fielding] PR#3821
4043 *) Added PassAllEnv; makes server's entire environment available
4044 to CGIs and SSIs executed within directive's scope. [Ken Coar]
4046 *) ap_uuencode() always added two trailing '='s and encoding of
4047 8 bit characters on a machine with signed char may produced
4048 incorrect results. Additionally ap_uuencode() should now
4049 work correctly on EBCDIC platforms.
4050 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
4052 *) WIN32: Binary installer now runs the configuration DLL before
4053 the reboot prompt (which is only given if MSVCRT.DLL system
4054 DLL is new or updated). This should avoid the configuration
4055 directory being empty after installation. [Paul Sutton]
4056 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
4058 *) WIN32: Binary installer now creates Start menu options to start
4059 and stop Apache as a console application and to uninstall
4060 the Apache service on NT. [Paul Sutton] PR#3741
4062 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
4064 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
4065 have been reported with flock() locking (probably related to kernel
4066 version). [Dean Gaudet] PR#2723, 3531
4068 *) Using APACI, the main config file (usually httpd.conf) was
4069 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
4070 <wsanchez@apple.com>]
4072 *) PORT: AIX does not require the SHARED_CODE "hack"
4073 [Ryan Bloom <rbb@raleigh.ibm.com>]
4075 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
4076 avoidance code added in 1.3.3.
4077 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
4079 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
4080 for 8-bit safeness. [Dean Gaudet]
4082 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
4083 because SPARCs have a small machine-specific maximum size for the Global
4084 Offset Table which is often exceeded when compiling one of the larger
4085 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
4087 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
4088 DSO/DLL section because it's a directive from mod_status and isn't
4089 available before the DLL of mod_status is loaded.
4090 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
4092 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
4093 continuation facility in Apache's configuration files which could
4094 lead to a buffer overflow situation.
4095 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
4097 *) Make documentation and error messages of APACI's --activate-module=FILE
4098 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995
4100 *) Fix the gcc version check (for enabling the `inline' facility) to
4101 really support all future gcc versions >= 2.7 until we know more.
4102 [John Tobey <jtobey@banta-im.com>] PR#3983
4104 *) Let APACI's configure script correctly complain for unknown --enable-XXX
4105 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
4107 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
4108 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
4109 possible buffer overflows. [Ralf S. Engelschall]
4111 *) Remove no longer used non-API function ap_single_module_init().
4112 [Ralf S. Engelschall]
4114 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
4117 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
4118 to make platform installations easier. [Wilfredo Sanchez]
4120 *) In configure, do not append the target name to the directory path if
4121 the path already contains "apache". [Ralf S. Engelschall]
4123 *) SIGPIPE is now ignored by the server core. The request write routines
4124 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
4125 correctly check for output errors and mark the connection as aborted.
4126 Replaced many direct (unchecked) calls to ap_b* routines with the
4127 analogous ap_r* calls. [Roy Fielding]
4129 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
4130 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
4131 Furthermore map lookups for non-existent keys are now cached as well.
4132 Additionally "txt" maps are now parsed with simple string functions
4133 instead of using ap_pregcomp(). As a side effect a bug that prevented
4134 the usage of keys containing the "," character was fixed.
4135 The changes drastically improve the performance when large rewrite maps
4137 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
4139 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
4140 other than GET, and const'd the definition of method in request_rec.
4143 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
4145 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
4146 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
4148 *) Add %V to mod_log_config, this logs the hostname according to the
4149 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
4150 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
4152 *) Add support for \n and \t to mod_log_config, can be used to produce
4153 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
4155 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
4157 *) Added informative error messages for failed munmap() and fseek() calls
4158 in http_core.c. [John Bley, Roy Fielding]
4160 *) Added some informative error messages for some failed malloc()
4161 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
4163 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
4164 is removed. This allows <Directory proxy:*> directives to work and
4165 prevents invalid requests from killing the process.
4166 [Brian Havard <brianh@kheldar.apana.org.au>]
4168 *) Reorganised FAQ document.
4169 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
4171 *) src/support/: The ApacheBench benchmark program was overhauled by
4172 David N. Welton: you can now have it generate an HTML TABLE, presumably
4173 for integration into other HTML sources. David updated the ab man page
4174 as well and added some missing descriptions. Thanks!
4175 [David N. Welton <davidw@prosa.it>]
4177 *) Win32: The filename validity checker now allows filenames containing
4178 characters in the range 0x80 to 0xff (for example accented characters).
4179 [Paul Sutton] PR#3890
4181 *) Added conditional logging based upon environment variables to
4182 mod_log_config. mod_log_referer and mod_log_agent
4183 are now deprecated. [Ken Coar]
4185 *) Allow apache acting as a proxy server to relay the real
4186 reason of a failure to a client rather than the "internal
4187 server error" it does currently. The general exposure mechanism
4188 can be triggered by any module by setting the "verbose-error-to"
4189 note to "*"; this allows more than just proxy errors to be exposed.
4190 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
4192 *) Moved man pages for ab and apachectrl to section 8.
4193 [Wilfredo Sanchez, Roy Fielding]
4195 *) Added -S option to install.sh so that options can be passed to
4196 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
4198 *) Tweak modules Makefile generated by Configure so that it handles
4199 the test case of no modules being selected. [chaz@reliant.com]
4201 *) Added a <LimitExcept method ...> sectioning directive that allows
4202 the user to assign authentication control to any HTTP method that
4203 is *not* given in the argument list; i.e., the logical negation
4204 of the <Limit> directive. This is particularly useful for controlling
4205 access on methods unknown to the Apache core, but perhaps known by
4206 some module or CGI script. [Roy Fielding, Tony Finch]
4208 *) Prevent apachectl from complaining if the PIDFILE exists but
4209 does not contain a process id, as might occur if the server is
4210 being rapidly restarted. [Wilfredo Sanchez]
4212 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
4214 *) Entity tag comparisons for If-Match and If-None-Match were not being
4215 performed correctly -- weak tags might cause false positives. Also,
4216 strong comparison wasn't properly enforced in all cases.
4217 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
4219 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
4222 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
4223 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
4225 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
4226 to util.c for parsing an HTTP header field value to extract the next
4227 list item, taking into account the possible presence of nested comments,
4228 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
4229 insignificant whitespace and lowercases non-quoted tokens.
4230 [Roy Fielding] PR#2065
4232 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
4233 code different from 500. This allows the proxy to, e.g., return
4234 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
4236 *) Fix ordering of language variants for the case where the traditional
4237 negotiation algorithm is being used with multiple language variants
4238 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
4240 *) Do not round the TCN quality calculation to 5 decimal places,
4241 unlike RFC 2296, because the calculation might need 12 decimal places
4242 to get the right result. [Roy Fielding]
4244 *) Remove unused code to disable transparent negotiation when
4245 negotiating on encoding only, as we now handle encoding too
4246 (though this is nonstandard for TCN), remove charset=ISO-8859-1
4247 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
4248 some debugging statements within mod_negotiation. [Koen Holtman]
4250 *) Fixed a rare memory corruption possibility in mod_dir if the index
4251 file is negotiable and no acceptable variant can be found.
4252 [Dean Gaudet, Roy Fielding, Martin Kraemer]
4254 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
4255 searching the Win32 registry for script interpreters.
4258 *) Win32: The compiled-in default filename for the error log is now
4259 error.log, which matches the default in the distributed httpd.conf.
4262 *) Win32: Any error messages from -i or -u command line options are now
4263 displayed on the console output rather than sent to the error log.
4264 Also the "Running Apache..." message is not output unless Apache is
4265 going to serve requests. [Paul Sutton]
4267 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
4268 and use a private significator ('$apr1$') to mark passwords as
4269 being smashed with our own algorithm. Also abstract the password
4270 checking into a new ap_validate_password() routine. [Ken Coar]
4272 *) Win32: The filename validity checker now allows "COM" but refuses
4273 access to "COM1" through "COM4". This allows filenames such
4274 as "com.name" to be served. [Paul Sutton] PR#3769.
4276 *) BS2000: Adapt to the new ufork() system call interface which will
4277 make subtasking easier on the OSD/POSIX mainframe environment.
4280 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
4281 ap_compat.h. [David White <david@persimmon.com>] PR#3725
4283 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
4284 use `.db' instead of `.pag' not only for FreeBSD, but also when
4285 the NDBM library looks like Berkeley-DB based.
4286 [Ralf S. Engelschall] PR#3773
4288 *) Add ability to handle DES or MD5 authentication passwords.
4289 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
4291 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
4293 *) SECURITY: Avoid some buffer overflow problems when escaping
4294 quoted strings. (This overflow was on the heap and we believe
4295 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
4297 *) Let src/Configure be aware of CFLAGS options starting with plus
4298 signs as it's the case for the HP/UX compiler.
4299 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
4301 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
4302 and check to see if the tar we wind up with supports '-h'.
4303 [Jim Jagielski] PR#3671
4305 *) A consistent and conservative style for all shell scripts has been
4306 implemented. Basically, all shell string tests use the traditional
4307 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
4308 to protect against bare null variable strings (ie: wrapping both
4309 sides with double quotes and prepending 'x'). 'x' was chosen
4310 because it's more universal and hopefully easier for old shell
4311 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
4314 *) The status module now prints out both the main server generation as
4315 well as the generation of each process. Also, the vhost info is
4316 printed with '?notable'. [Jim Jagielski]
4318 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
4319 and this makes its functions available to things in src/support.
4322 Changes with Apache 1.3.4
4324 *) Renamed macros status_drops_connection to ap_status_drops_connection
4325 and vestigial scan_script_header to ap_scan_script_header_err,
4326 mostly for aesthetic reasons. [Roy Fielding]
4328 *) The query switch "httpd -S" didn't exit after showing the
4329 vhost settings. That was inconsistent with the other query functions.
4332 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4333 filename to the end of the STANDARD_MODULE_STUFF. Its
4334 presence at the beginning prevented reporting of the filename
4335 for modules compiled before 1 January 1999. [Ken Coar]
4337 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4338 to detect and prevent access to special DOS device file names.
4339 [Paul Sutton, Ken Parzygnat]
4341 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4342 and Makefile_win32_debug.txt (debug build) that work on Win95.
4343 Run each of the following from the src directory:
4344 nmake /f Makefile_win32.txt # compiles normal build
4345 nmake /f Makefile_win32.txt install # compiles and installs
4346 nmake /f Makefile_win32.txt clean # removes compiled junk
4347 nmake /f Makefile_win32_debug.txt # compiles debug build
4348 nmake /f Makefile_win32_debug.txt install
4349 nmake /f Makefile_win32_debug.txt clean
4352 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4353 to build binary distributions. [Lars Eilebrecht]
4355 *) IndexOptions SuppressColumnSorting only turned off making
4356 the column headers anchors; you could still change the display
4357 order by manually adding a '?N=A' or similar query string to the
4358 URL. Now SuppressColumnSorting locks in the sort order so
4359 it can't be overridden this way. [Ken Coar]
4361 *) Added IndexOrderDefault directive to supply a default sort order
4362 for FancyIndexed directory listings. [Ken Coar] PR#1699
4364 *) Change the ap_assert macro to a variant that works on all platforms.
4365 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4367 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4368 search for an underscore on dlsym() (as it's already the case
4369 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4371 *) Small fix for mod_env.html: The module was documented as to be _not_
4372 compiled into Apache per default, although it _IS_ compiled into
4373 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4375 *) Instead of fixing a bug in the generation procedure for config.status (a
4376 backslash was missing) we remove the bug together with it's complete
4377 context because the special cases of the past can now no longer occur
4378 because of the recent magic for the --with-layout default.
4379 [Ralf S. Engelschall] PR#3590
4381 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4382 making sure the src/support/ tools are _forced_ to be build last (they
4383 depend on other libraries).
4384 [Markus Theissinger <markus.theissinger@gmx.de>]
4386 *) Fix installation procedure: Now that os-inline.c is actually used (a
4387 recently fixed bug prevented this) we need to also install os-include.c
4388 in addition to os.h into the PREFIX/include/ location or building of
4389 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4391 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4392 allow us to distinguish between a garbled DSO (or even a file which isn't
4393 an Apache module DSO at all) and a DSO which doesn't match the current
4394 Apache API. [Ralf S. Engelschall] PR#3152
4396 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4397 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4398 match case insensitive (this especially avoids nasty patterns like
4399 `[tT][eE][sS][tT]'). Second two additional internal map functions
4400 `escape' and `unescape' were added which can be used to escape/unescape
4401 to/from hex-encodings in URLs parts (this is especially useful in
4402 combination with map lookups).
4403 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4405 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4406 forgotten (because it was a macro) in the symbol renaming process.
4407 [Ralf S. Engelschall]
4409 *) Fix some inconsistencies related to the scopes of directives. The only
4410 user visible change is that the directives `UseCanonicalName' and
4411 `ContentDigest' now use the (more correct) `Options' scope instead of
4412 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4414 *) Using DSO, the Server token was being mangled. Specifically, the
4415 module's token was being added first before the Apache token. This
4416 has been fixed. [Jim Jagielski]
4418 *) Major overhaul of mod_negotiation.c, part 2.
4419 - properly handle "identity" within Accept-Encoding.
4420 - allow encoded variants in RVSA negotiation and let them appear in
4421 the Alternates field using the non-standard "encoding" tag-list.
4422 - fixed both negotiation algorithms so that an explicitly accepted
4423 encoding is preferred over no encoding if "identity" is not
4424 included within Accept-Encoding.
4425 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4426 of large substring sequences.
4427 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4430 *) Major overhaul of mod_negotiation.c, part 1.
4431 - cleanups to mod_negotiation comments and code structure
4432 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4433 support for everything in the upcoming HTTP/1.1
4434 revision (draft-ietf-http-v11-spec-rev-06.txt).
4435 - language tag matching also handles tags with more than 2
4437 - empty Accept, Accept-Language, Accept-Charset headers are
4438 processed correctly; previously an empty header would make all
4439 values acceptable instead of unacceptable.
4440 - allowed for q values in Accept-Encoding
4441 - added support for transparent content negotiation (rfc2295 and
4442 rfc2296) (though we do not implement all features in these drafts,
4443 e.g. no feature negotiation). Removed old experimental version.
4444 - implemented 'structured entity tags' for better cache correctness
4445 (structured entity tags ensure that caches which can deal with Vary
4446 will (eventually) be updated if the set of variants on the server
4448 - this involved adding a vlist_validator element to request_rec
4449 - this involved adding the ap_make_etag() function to the global API
4450 - modified guessing of charsets used by Apache negotiation algorithm
4451 to guess 'no charset' if the variant is not a text/* type
4452 - added code to sort multiviews variants into a canonical order so that
4453 negotiation results are consistent across backup/restores and mirrors
4454 - removed possibility of a type map file resolving to another type map
4455 file as its best variant
4456 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4458 *) RFC2396 allows the syntax http://host:/path (with no port number)

4473 rather late (too late for some invocations of TestCompile).
4474 This improves the make environment available to TestCompile and
4475 the *.module scripts. [Martin Kraemer]
4477 *) The hashbang emulation code in ap_execve.c would interpret
4478 #!/hashbang/scripts correctly, but failed to fall back to a
4479 standard shell for scripts which did NOT start with #!
4480 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4482 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4485 *) Update APXS manual page: some -q option arguments were missing
4486 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4488 *) Cleanup the command line options: `-?' was documented to show
4489 the usage list but does it with an error because `?' is not a valid
4490 command. OTOH a lot of users expect `-h' to print such a usage list and
4491 instead are annoyed for ages by our huge unreadable list of directives.
4492 So we now changed the command line options this way:
4494 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4495 very similar to the popular linker option.
4497 Intent: while -l gives the small list of modules, -L now gives the
4498 large list of directives implemented by these modules. This is also
4499 consistent with -v (short version info) and -V (large version info).
4501 Intent: it's now the expected option ;-)
4502 The manual page was adjusted accordingly.

4505 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4506 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4508 *) Removed recently introduced bugs and disfigurements in APACI:
4509 o fixed argument line processing: using $args was broken: It was not
4510 initialized and using args="$args $apc_option" and even args="$args
4511 \"$apc_option\"" fails in the second processing round for any arguments
4512 containing whitespaces. The only correct way is to use the construct
4513 "$@" (but not possible here) or iterate _both_ times over the implicit
4514 argument line (no argument to for-loop) which is what we now use.
4515 o make --with-layout=Apache the default without creating
4516 redundancy (copying the --with-layout block in the argument parsing
4517 loop). We achieve this by using the "$@" construct together with the
4518 `set' command to prepend --with-layout=Apache to the command line in
4519 case --with-layout is not used.
4520 o fixed auto-suffix handling now that config.layout exists.
4521 Paths which are auto-suffixed are marked with a trailing plus sign in
4522 config.layout and every path now can be marked this way (not only the
4523 four paths for which we do it currently). Additionally the suffix is
4524 no longer a static one. Instead it's now `/<target>' where <target> is
4525 the argument of the --target option or per default `httpd'.
4526 o allow also tabs (and only spaces) where we match whitespaces
4527 o various fixes and cleanups related to used shell coding style
4528 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4529 o trimmed output of --help to fit into 80 columns

4532 *) Added two new core API functions, ap_single_module_configure() and
4533 ap_single_module_init(), which are now used by mod_so to configure a module
4534 after loading. [Ralf S. Engelschall]
4536 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4537 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4538 of ap_config.h to allow serialized accept for multiport listens.
4539 [Roy Fielding, Curt Sampson] PR#3120
4541 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4542 of ap_config.h that would skip several defines if DEFAULT_GROUP
4543 was overridden. [Roy Fielding]
4545 *) PORT: The I86 version of DGUX has support for strncasecmp and
4546 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4548 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4549 defined before it might be used. [Victor Khimenko]
4551 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4552 [Tom Serkowski <tks@bsdi.com>] PR#3453
4554 *) Make generation of src/Configuration.apaci more robust: It failed to
4555 differenciate between modules when one module name was a postfix of
4556 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4557 just XXX (think about totally non-standard names like "apache_ssl", too).
4558 [Ralf S. Engelschall] PR#3380
4560 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4561 since 1.3b7) and make whitespace handling more robust (it failed horrible
4562 when whitespaces were present in the arguments of -D options).
4563 [Ralf S. Engelschall] PR#3240
4565 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4566 creates an external package shadow tree in DIR before the local build
4567 shadow tree is generated under DIR. This way one can have the extracted
4568 Apache distribution tree read-only on NFS or CDROM and still build Apache
4569 from these sources. An automatically triggered VPATH-like mechanism is
4570 provided through the TOP variable, too.

4573 *) Fix negotiation so that a Vary response header is correctly
4574 generated when, for a particular dimension, variants only vary
4575 in having or not having a value for that dimension. [Paul Sutton]
4577 *) Fix negotiation so that we prefer an encoded variant over an
4578 unencoded variant if the user-agent explicitly says it can
4579 accept that encoding. Previously we always preferred the unencoded
4581 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4583 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4584 and the usage page was inconsistent with the functionality and manpage.
4585 [Ralf S. Engelschall]
4587 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4588 They can occur multiple times and their arguments (`xxx') are passed AS
4589 IS to the compiler/linker command. [Ralf S. Engelschall]
4591 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4592 procedure of mod_rewrite: very long keys were truncated.
4593 [Ralf S. Engelschall]
4595 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4596 identifier, currently "Apache" and "GNU" are pre-defined in the file
4597 config.layout. Custom layouts are possible by using FILE:ID as the
4598 argument where the layout ID is taken from FILE.
4600 The config.layout file consists of <Layout ID>..</Layout> sections
4601 where inside those sections "path_variable: path_value" pairs can be
4602 specified. These lines are converted to path_variable='path_value'.
4604 *) Add a DefaultLanguage directive so that files missing a language
4605 extension (e.g., .fr, .de) can be labelled as being some other
4606 default language. DefaultLanguage can appear in <Directory> and
4607 <Files> containers as well as .htaccess files. [Paul Sutton]
4610 *) Fix TARGET configuration when configuring and installing using
4611 APACI configure. TARGET now defines the basename of the configuration
4612 file, startup script, manual page, etc. log_error_core() now reports
4613 the server binary name given by argv[0]. TARGET can now also be defined
4614 with --target=TARGET parameter passed to APACI configure.
4615 [Ralf Engelschall, Randy Terbush]
4617 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4618 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

4637 notice to the error log. It is not possible to send a 401 response
4638 and a redirect at the same time. [Lars Eilebrecht]
4640 *) Fallback to native compilers for IRIX-32 platform. It seems that
4641 a gcc 2.8.1 compiled apache is logging client addresses with all
4642 bits set (255.255.255.255). This is the second such problem caused
4643 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4646 *) Updated mime.types to reflect current Internet media types
4647 and include a URL to the registry.

4650 *) SECURITY: Do a more complete check in mod_include to avoid
4651 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323
4653 *) Add APACI --suexec-docroot and --suexec-logfile options which can be
4654 used to set the document root directory (DOC_ROOT) and the suexec
4655 logfile (LOG_EXEC), respectively. Additionally the --layout option
4656 was changed to show more information about the suEXEC setup.

4659 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
4660 and 507 (Insufficient Storage) for use by third-party modules.
4663 *) Enabled all of the WebDAV method names for use by third-party
4664 modules, Limit, and Script directives. That includes PATCH,
4665 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
4666 Improved mod_actions.c so that it can use any of the methods
4667 defined in httpd.h. Added ap_method_number_of(method) for

4691 the interpreter and the Win32 error code returned. [Marc Slemko]
4693 *) Disable sending of error-notes on a 500 (Internal Server Error) response
4694 since it often includes file path info. Enable sending of error-notes
4695 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
4697 *) http_config.c would respond with 501 (Method Not Implemented) if a
4698 content type handler was specified but could not be found, which
4699 should have been a 500 response. Likewise, mod_proxy.c would responsd
4700 with a 501 if the URI scheme is unrecognized instead of the correct
4701 response of 403 (Forbidden). [Roy Fielding]
4703 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
4704 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]
4706 *) Fix in mod_autoindex: for files where the last modified time stamp was
4707 unavailable, an empty string was printed which was 2 bytes short.
4708 The size and description columns were therefore not aligned correctly.
4709 [Martin Kraemer] (no PR#)

4712 release A17, the child fork() must be replaced by a _rfork().
4713 (BS2000 only) [Martin Kraemer]
4715 *) Add the actual server_rec structure of the specific Vhost to the
4716 scoreboard file and avoid a string copy (as well as allow some
4717 further future enhancements). [Harrie Hazewinkel
4718 <harrie.hazewinkel@jrc.it>]
4720 *) Add APACI --permute-module=foo:bar option which can be used to
4721 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4722 in the Configuration[.apaci] file. Two special and important variants are
4723 supported for the option argument: first BEGIN:foo which permutes module
4724 mod_foo with the begin of the module list, i.e. it `moves' the module to
4725 the begin of the list (gives it lowest priority). And second foo:END
4726 which permutes mod_foo with the end of the module list, i.e. it `moves'
4727 the module to the end of the list (gives it highest priority).

4769 *) Add a "default-handler" handler that calls the default_hander()
4770 function which is normally called for static content. This allows
4771 you to override a specific handler. [Marc Slemko]
4773 *) Further simplify checking for absolute paths by replacing an

4775 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
4777 *) Log an error if we encounter a malformed "require" directive
4778 in mod_auth if we know that we know that no other module can
4779 deal with it. [Marc Slemko]

4802 response when we already know the final status, which is mighty
4803 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4805 *) Remove extra trailing whitespace from the getline results as part
4806 of the protocol processing, which is extra nice because it works
4807 between continuation lines, is almost no cost in the normal case
4808 of no extra whitespace, and saves memory. [Roy Fielding]
4810 *) Added new HTTP status codes and default response bodies from the
4811 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
4812 HTTP Extension Framework (510) specifications. Did not add the
4813 WebDAV 424 and 425 codes because they are bogus. We don't use any

4954 determine whether a C header file exists or not. Because only this way
4955 we're safe against inter-header dependencies (which caused horrible
4956 portability problems). The only drawback is that we now have a CPP
4957 configuration variable which has to be determined first (we do a similar
4958 approach as GNU Autoconf does here). When all fails the user still has
4959 the possibility to override it manually via APACI or src/Configuration.
4960 As a fallback for the header check itself we can directly check the
4961 existance of the file under /usr/include, too.

5054 starting directory might send us to /home/).
5055 + When ftp login fails, (esp. when a user name was part of the
5056 URL already), we now return [401 Unauthorized ] to allow the
5057 browser to pop up an authorization dialog. This makes passwords
5058 slightly less visible (they don't appear in the regular log files)
5059 and implements a functionality that other www proxy servers
5063 *) Triggered by the recent "Via:" header changes, the proxy module would
5064 dump core for replies with invalid headers (e.g., duplicate

5460 other machinery within Apache. This is something of a kludge but
5461 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5463 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5464 pools and thus pollutes libap (until the pool stuff is moved there).
5467 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
5468 but case-insensitive platforms). New #define for this added to conf.h
5469 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
5471 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
5472 also works for OpenBSD 1.x. [Ralf S. Engelschall]
5474 *) PORT: Fix compilation problem on ARM Linux.
5475 [Sam Kington <sam@illuminated.co.uk>] PR#2443
5477 *) Let APACI's configure script determine some configuration parameters
5478 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5479 remove some of the classical hurdles for new users when setting up
5480 Apache. This is done per default because it is useful for the average
5481 user. Package authors can use the --without-confadjust option to disable
5482 these configuration adjustments.
5483 [Ralf S. Engelschall]
5485 *) Added an EXTRA_DEPS configuration parameter which can be used
5486 to add an extra Makefile dependency for the httpd target, for instance
5487 to external third-party libraries, etc.
5488 [Ralf S. Engelschall]
5490 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5491 as <IfModule>..</IfModule> sections) which can be used to skip or process
5492 contained commands dependend of ``-D PARAMETER'' options on the command
5493 line. This can be used to achieve logical conditions like <IfDefine
5494 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5495 and thus especially can be used for conditionally loading DSO-based
5496 modules via LoadModule, etc. [Ralf S. Engelschall]
5498 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
5500 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
5502 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
5503 truncated which forced following HTTP headers to be data in the HTTP
5504 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5507 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5508 in top-level configure script to avoid sed fails on some platforms (for
5509 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5510 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5512 *) Improve performance of directory listings (mod_autoindex) by comparing
5513 integer keys (last-modified and size) as integers rather than converting
5514 them to strings first. Also use a set of explicit byte tests rather
5515 than strcmp() to check for parent directory-ness of an entry. Oh, and
5516 make sure the parent directory (if displayed) is *always* listed first
5517 regardless of the sort key. Overall performance winnage should be good
5518 in CPU time, instruction cache, and memory usage, particularly for large
5519 directories. [Ken Coar]
5521 *) Add a tiny but useful goody to APACI's configure script: The generation
5522 of a config.status script (as GNU Autoconf does) which remembers the used
5523 configure command and hence can be used to restore the configuration by
5524 just re-running this script or for remembering the configuration between
5526 [Ralf S. Engelschall]
5528 *) Add httpd -t (test) option for running configuration syntax tests only.
5529 If something is broken it complains and exits with a return code
5530 non-equal to 0. This can be used manually by the user to check the Apache
5531 configuration after editing and is also automatically used by apachectl
5532 on (graceful) restart command to make sure Apache doesn't die on restarts
5533 because of a configuration which is now broken since the last (re)start.
5534 This way `apachectl restart' can be used inside cronjobs without having
5535 to expect Apache to be falling down. Additionally the httpd -t can be run
5536 via `apachectl configtest'.
5537 [Ralf S. Engelschall] PR#2393
5539 *) Minor display fix for "install" target of top-level Makefile:
5540 the displayed installation command was incorrect although the

5556 functions which are in libdld under HPUX 9/10.
5557 [Ralf S. Engelschall] PR#2378
5559 *) Make sure the "install" target of the top-level Makefile doesn't break
5560 because of a return code of 1 from an "if" (for instance under braindead
5561 Ultrix the result code of an "if" construct is 1 if the "then" clause
5562 didn't match). [Ralf S. Engelschall]
5564 *) Add an additional "dummy" target to the "$(LIB)" target in generated
5565 modules/xxx/Makefile's to avoid problems with SVR4 Make under "full-DSO"
5566 situation (no libxxx.a built, only mod_xxx.so's) where LIB and OBJS are
5567 empty. [Ralf S. Engelschall, Dean Gaudet, Martin Kraemer]
5569 *) Replace two bad sprintf() calls with ap_snprintf() variants in
5570 mod_rewrite. [Ralf S. Engelschall]
5572 *) Fix missing usage description for MetaFiles directive.
5573 [David MacKenzie <djm@va.pubnix.com>] PR#2384
5575 *) mod_log_config wouldn't let vhosts use log formats defined in the
5576 main server. [Christof Damian <damian@mediaconsult.com>] PR#2090
5578 *) mod_usertrack was corrupting the client hostname. As part of the

5583 *) Fix a typo in pool debugging code. [Alvaro Martinez Echevarria]
5585 *) mod_unique_id did not work on alpha linux (in general on any
5586 architecture that has 64-bit time_t).
5587 [Alvaro Martinez Echevarria]
5589 *) PORT: Make SCO 5 (and probably 3) compile again. [Ben Laurie]
5591 *) PORT: NCR MPRAS systems have the same bug with SIGHUP restart that
5592 Solaris systems experience. So define WORKAROUND_SOLARIS_BUG.
5593 [Klaus Weber <kweber@chephren.germany.ncr.com>] PR#1973
5595 *) Change "Options None" to "Options FollowSymLinks" in the
5596 <Directory /> section of the default access.conf-dist
5597 (and -win even though it doesn't matter there). This has better
5598 performance, and more intuitive semantics. [Dean Gaudet]
5600 *) PORT: Updated support for UTS 2.1.2.

5604 API changes in the child spawning area.
5605 [Jens-Uwe Mager <jum@helios.de>]
5607 *) Workaround for configure script and old `test' commands which do not
5608 support the -x flag (for instance under platforms like Ultrix). This is
5609 solved by another helper script findprg.sh which searches for Perl and
5610 Awk like PrintPath but _via different names_.

5635 Changes with Apache 1.3.0
5637 *) Using a type map file as a custom error document was not possible.

5640 *) Avoid problems with braindead Awks by additionally searching for gawk
5641 and nawk in APACI's configure script.

5644 *) Rename md5.h to ap_md5.h to avoid conflicts with native MD5 on
5645 some systems. [Randy Terbush]
5647 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
5648 more proper ap_log_error() variants.
5649 [Ralf S. Engelschall]
5651 *) Make sure the argument for the --add-module option to APACI's configure
5652 script is of type [path/to/]mod_xxx.c because all calculations inside
5653 configure and src/Configure depend on this.
5654 [Ralf S. Engelschall] PR#2307
5656 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error
5657 in mod_mime, mod_log_referer, mod_log_agent, and mod_log_config.
5660 *) Various OS/2 cleanups ["Brian Havard" <brianh@kheldar.apana.org.au>]
5662 *) PORT: QNX needed a #include <sys/mman.h>; and now it uses flock
5663 serialized accept to handle multiple sockets.
5664 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2295, 2296
5666 *) Have NT properly set the directory for CGI scripts
5667 (& other spawned children)
5668 [W G Stoddard <wgstodda@us.ibm.com>]
5670 *) Propagate environment to CGI scripts correctly in Win32.
5671 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
5673 *) Some symbol renaming:
5674 ap_spawn_child_err became ap_spawn_child
5675 ap_spawn_child_err_buff became ap_bspawn_child
5676 spawn_child was obsoleted and moved to compat.h
5679 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5680 programs: ap_spawn_child_err() is used and the Win32 case now uses
5681 CreateProcess() instead of a low-level execl() (which caused problems in
5682 the past under Win32).
5683 [Ralf S. Engelschall]
5685 *) A few cosmetics and trivial enhancements to APXS to make the
5686 generated Makefile more user friendly. [Ralf S. Engelschall]
5688 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5689 was updated to use the normal apache error processing, thereby allowing
5690 proxy errors to be treated by ErrorDocument's as well. For this
5691 purpose, a new module-to-core communication variable "error-notes"
5692 was introduced; the proxy (and possibly other modules) communicates
5693 its error text using this variable. Its content is copied to a new
5694 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5695 The old proxy special error routine ap_proxy_log_uerror()
5696 was replaced by regular ap_log_error() calls, many messages were made
5698 [Martin Kraemer] PR#494, 1259
5700 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5703 *) Transform the configure message "You need root privileges for suEXEC"
5704 from a fatal error into a (more friendly) warning because the building
5705 ("make") of Apache we can allow, of course. Root privileges are needed
5706 only for the installation step ("make install"). So make sure the
5707 user is aware of this fact but let him proceed as long as he can.
5708 [Ralf S. Engelschall] PR#2288
5710 *) Renamed three more functions to common ap_ prefix which we missed at the
5711 Big Symbol Renaming because they're #defines and not real C functions:
5712 is_default_port(), default_port(), http_method().
5713 [Ralf S. Engelschall]
5715 *) A zero-length name after a $ in an SSI document should cause
5716 just the $ to be in the expansion. This was broken during the
5717 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
5719 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
5720 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252

5723 used under AIX) because of recent changes to function names.
5724 [Ralf S. Engelschall]
5726 Changes with Apache 1.3b7
5728 *) Make sure a MIME-type can be forced via a RewriteRule even when no
5729 substitution takes place, for instance via the following rule:
5730 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
5731 requested by users in the past to force a single script without a .cgi
5732 extension and outside any cgi-bin dirs to be executed as a CGI program.
5733 [Ralf S. Engelschall] PR#2254
5735 *) A fix for protocol issues surrounding 400, 408, and
5736 414 responses. [Ed Korthof]
5738 *) Ignore MaxRequestsPerChild on WIN32. [Brian Behlendorf]
5740 *) Fix discrepancy in proxy_ftp.c which was causing failures when
5741 trying to connect to certain ftpd's, such as anonftpd.
5742 [Rick Ohnemus <rick@ecompcon.com>]
5744 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
5745 logfile instead of fiddling around itself with child spawning stuff.
5746 [Ralf S. Engelschall]
5748 *) Made RefererIgnore case-insensitive.
5750 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
5753 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
5754 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
5757 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
5759 *) Fix support script `dbmmanage': It was unable to handle some sort
5760 of passwords, especially passwords with "0" chars.
5761 [Ralf S. Engelschall] PR#2242
5763 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5764 [Ben Laurie] PR#2238
5766 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5767 library), so CGI handling has been changed to use Win32 native handles
5768 instead of C file descriptors.
5769 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5771 *) The proxy cache would store an incorrect content-length in the cached
5772 file copy after a cache update. That resulted in repeated fetching
5773 of the original copy instead of using the cached copy.
5774 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5776 *) The Makefiles assumed that DSO files are build via $(LD). This
5777 is broken for two reasons: First we never defined at least LD=ld
5778 somewhere to make sure this works (it was silently assumed that most Make
5779 provide a built-in LD definition - ARGL!) and second using the generic LD
5780 variable is not the truth. Instead a special variable named LD_SHLIB is
5781 reasonable because although "ld" is usually the default, the command for
5782 building DSO files can be "libtool" or even "cc" on some systems.
5783 [Ralf S. Engelschall]
5785 *) Replace the AddVersionPlatform directive with ServerTokens which
5786 provides for more control over the format of the Server:
5787 header line. SERVER_SUBVERSION is no longer supported;
5788 all module should use the ap_add_version_component()
5789 API function instead. [Jim Jagielski]
5791 *) Support for the NCR MP/RAS 3.0
5792 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5794 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5795 not retrieved in src/Configure and thus was not useable.
5796 [Ralf S. Engelschall]
5798 *) Various Makefile consistency cleanups:
5799 - make OSDIR also automatically be relative to src/ like INCDIR
5800 - SUBDIRS is now generated in src/Makefile only and not in
5801 Makefile.config because it is a local define for this location.
5802 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5803 any Makefile but make sure that at least the "-K inline" is kept in
5805 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5806 - updated the dependencies theirself
5807 - removed not existing SHLIB variable from "clean" targets
5808 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5809 already exists and OBJS_PIC are also just plain objects and have not
5810 directly to do with "shared" things. The only difference is that they
5811 contain PIC. So OBJS_PIC is the more canonical name.
5812 - Updated the Makefile-dependency lines for OBJS_PIC
5813 - Removed the Makefile-dependency line in Configure to avoid double
5815 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5816 of xxx.lo as GNU libtool does with its PIC objects
5817 - reduce local complexity in modules Makefile.tmpl by moving the last
5818 existing target "depend" to the generation section in Configure, too.
5819 - removed the historical $(SPACER) which was used in the past together
5820 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5821 is no longer needed.
5822 - force the build and run of the gen_xxx programs under main/ as the
5823 first step before building the objects because it looks cleaner
5824 [Ralf S. Engelschall]
5826 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5829 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5832 *) WIN32: Don't force ISAPI headers to finish with \n.
5833 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5835 *) When opening "configuration" files (like httpd.conf, htaccess
5836 and htpasswd), Apache will not allow them to be non-/dev/null
5837 device files. This closes a DoS hole. At the same time,
5838 we use ap_pfopen to open these files to handle timeouts.
5839 [Jim Jagielski, Martin Kraemer]
5841 *) Apache will now log the reason its httpd children exit if they exit
5842 due to an unexpected signal. (It requires a new porting define,
5843 SYS_SIGLIST, which if defined should point to a list of text
5844 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5846 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5847 like WIN32. Before, Win32 CGI's could have had sporadic failures
5848 if a chdir call from one thread was made between another chdir call
5849 and a spawn in another thread. So, for now don't chdir for CGI scripts
5850 in WIN32. The current CGI "spec" is unclear as to whether it's
5851 necessary. Long-term fix is to either serialize the chdir/spawn combo
5852 or use WIN32 native calls to spawn a process. This temp fix was
5853 necessary to remove this as a showstopper for 1.3's release.
5856 *) Cleanup the suEXEC support in APACI and make it more safe:
5857 1. Add big fat hint in INSTALL about risks and to read the
5858 htdocs/manual/suexec.html document before using the suexec-related
5860 2. Make sure the user has at least provided one --suexec-xxxx option
5861 (specifies suEXEC parameters) in addition to --enable-suexec option.
5862 If only --enable-suexec is given APACI stops with a hint to INSTALL
5863 and htdocs/manual/suexec.html documents.
5864 3. Provide two additional --suexec-xxxx options to make the suEXEC
5865 configuration complete (especially for package maintainers who else
5866 had to patch the source tree) by providing ways to configure minimal
5867 UID/GID and safe PATH, too.
5868 [Ralf S. Engelschall]
5870 *) Cleanup of the `configure --shadow' process:
5871 - make sure the configure script creates its temporary files in the
5872 shadow tree to avoid conflicts with parallel configure runs
5873 - removed unnecessary option "-r" from "rm" call for Makefiles
5874 - make sure the configure scripts creates the shadow-wrapper Makefile
5875 only when no shadow trees already exists
5876 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5877 when no more shadow trees exists
5878 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5879 as fast (in the past it needed 70sec, now it runs just 38sec)
5880 - make sure CVS does not complain about the created files
5881 Makefille.<gnutriple> and directories src.<gnutriple>
5882 [Ralf S. Engelschall]
5884 *) Added the ap_add_version_component() API routine and the
5885 AddVersionPlatform core directive. The first allows modules to
5886 declare themselves in the Server response header field value,
5887 augmenting the SERVER_SUBVERSION define in the Configuration file
5888 with run-time settings (more useful in a loadable-module environment).
5889 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5890 into the server version string. [Ken Coar] PR#2056
5892 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5895 *) Emit the "Accept-Range" header for the default handler.
5896 [Brian Behlendorf] PR#1464
5898 *) Add a note to httpd.conf-dist that apache will on some systems fail
5899 to start when the Group # is set to a negative or large positive value.
5902 *) Make sure the module execution order is correct even when some modules
5903 are loaded under runtime (`LoadModule') via the DSO mechanism:
5904 1. The list of loaded modules is now a dynamically allocated one
5905 and not the original statically list from modules.c
5906 2. The loaded modules are now correctly setup by LoadModule for
5907 later use by the AddModule command.
5908 3. When the DSO mechanism for modules is used APACI's `install'
5909 target now enables all created `LoadModule' lines per default because
5910 this is both already expected by the user _and_ needed to avoid
5911 confusion with the next point and reduces the Makefile.tmpl complexity
5912 4. When the DSO mechanism for modules is used, APACI's `install'
5913 target now additionally makes sure the module list is reconstructed
5914 via a complete `ClearModuleList+AddModule...' entry.
5915 5. The support tool `apxs' now also makes sure an AddModule command
5916 is added in addition to the LoadModule command.
5917 6. The modules.c generation was extended to now contain two
5918 comments to make sure no one is confused by the confusing terminology
5919 of loading/linking (we use load=link+load & link=activate instead of
5920 the obvious load=activate & link=link :-( )
5921 This way now there is no longer a difference under execution time between
5922 statically and dynamically linked modules.
5923 [Ralf S. Engelschall]
5925 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5926 Big Symbol Renaming. [Ralf S. Engelschall]
5928 *) Add a comment to mod_example.c showing the format of a FLAG command
5931 *) Standardized the time format in mod_status to match that of other
5932 places in the code (e.g. DATE_GMT). PR#1551
5934 *) Fix handling of %Z in timefmt strings for those platforms with no time
5935 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5938 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5939 feature compatible with 'UseCanonicalName off' by changing
5940 r->server->server_hostname to ap_get_server_name(). And I changed some
5941 functions which use r->server->port to use ap_get_server_port() instead,
5942 because if there's no Port directive in the config r->server->port is 0.
5945 *) get/set_module_config are trivial enough to be better off inline. Worth
5946 1.5% performance boost. [Dean Gaudet]
5948 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5949 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5952 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5953 the task environment to the unprivileged User id. Otherwise CGI scripts
5954 would have a way to gain super user access. [Martin Kraemer]
5956 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5957 absolute path, only log base name of logging source as is done
5958 in unix. [Martin Kraemer]
5960 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5961 the encoding type from the Accept-Encoding header (if it's there)
5962 and use it in the response, as that's probably what it'll be expecting.
5963 [Ronald.Tschalaer@psi.ch]
5965 *) Fix to mod_alias: translate_alias_redir is dealing with
5966 a URI, not a filename, so the check for drive letters for win32
5967 and emx is not necessary. [Dean Gaudet]

5976 of APEXIT_CHILDFATAL) the parent process to abort and
5977 shutdown the server if the error in the child process was
5978 fatal enough. [Jim Jagielski]

5992 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5993 Additionally the checks for finding the vendor DSO library were moved
5994 from mod_so.c to Configure because first it needs $PLAT etc. and second
5995 mod_so already uses an abstraction layer and does not fiddle with the
5996 vendor functions itself.
5997 [Jens-Uwe Mager, Ralf S. Engelschall]
5999 *) PORT: Some optimization defines for NetBSD
6000 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
6002 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
6003 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
6005 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
6006 AIX variants should work fine, too. Even AIX 3.x should work). This is
6007 accomplished by using the free DSO emulation code from Jens-Uwe Mager
6008 which we put into a os/unix/os-dso-aix.c file.
6009 [Ralf S. Engelschall]
6011 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
6012 that we should use NET_SIZE_T == int but the include files force size_t.
6013 [Ralf S. Engelschall]
6015 *) Fix two bugs in select() handling in http_main.c.
6018 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
6019 is unset (as it is in situations like timeouts) where it is unclear
6020 whether errno is set or not. [Martin Kraemer]
6022 *) Just having APACI's localstatedir is too general and not enough for most
6023 of the systems. 1.3b6 again required manual APACI patches by package
6024 maintainers from RedHat and FreeBSD because for their filesystem layout a
6025 little bit more flexibility in configuring the paths is needed. Hence we
6026 provide three additional configure options (--runtimedir, --logfiledir,
6027 --proxycachedir) which now can be used for more granular adjustments if
6028 --localstatedir is not enough to fit the particular needs. As a nice
6029 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
6030 [Ralf S. Engelschall]
6032 *) Make the install root for "make install" in APACI's Makefile overrideable
6033 by package authors. This way we are even more friendly to package
6034 maintainers (especially Debian and RedHat) who build for the real prefix
6035 via "configure --prefix=/<real>" but use a different local prefix via
6036 "make root=/tmp/apache install" for rolling the package without bristling
6037 the target location on their system.
6038 [Ralf S. Engelschall]
6040 *) Workaround sed limitations in APACI's configure script by now
6041 substituting in chunks of 50 commands (because for instance HPUX's vendor
6042 sed has a limit of max. 98 commands)
6043 [Ralf S. Engelschall] PR#2136

6046 [Ralf S. Engelschall] PR#2140
6048 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
6049 RENAMING process because they are defined as pre-processor macros instead
6050 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
6051 [Ralf S. Engelschall]
6053 *) Workaround braindead AWK's when generating ap_config.h: The split() and
6054 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
6055 [Ralf S. Engelschall] PR#2139
6057 *) Various bugfixes and cleanups for the APACI configure script:
6058 o fix IFS handling for _nested_ situation
6059 o fix Perl interpreter search: take first one found instead of last one
6060 o fix DSO consistency check
6061 o print error messages to stderr instead of stdout
6062 o add install-quiet for --shadow situation to Makefile stub
6063 o reduce complexity by avoiding sed-hacks for rule and module list loops
6064 [Ralf S. Engelschall]
6066 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
6068 *) Make sure the input field separator (IFS) shell variable is explicitly
6069 initialized correctly before _every_ `for' loop and also restored after
6070 the loops. [Ralf S. Engelschall]
6072 *) Make sure that "make install" doesn't overwrite the `mime.types' and
6073 `magic' files from an existing Apache installation. Because people often
6074 customize these for own MIME and content types.

6080 *) Fix the path to the ScoreBoardFile in the install-config target, too.
6081 [Ralf S. Engelschall] PR#2105
6083 *) Let "configure" clear out the users parameters (provided as shell
6084 variables) to avoid side-effects in "src/Configure" when the user
6085 exported them (which is not needed, but some users do it).
6086 [Ralf S. Engelschall] PR#2101
6088 *) Provide backward compatibility from some old src/Configuration.tmpl
6089 parameter names to the canonical Autoconf-style shell variable names. For

6097 *) Make `configure --compat' more "compatible" by first
6098 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
6099 second by making sure the "avoid-bristling-suffix" /apache is not

6109 *) Fix the path to the MimeMagicFile in the install-config target, too.
6110 [Ralf S. Engelschall] PR#2089
6112 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
6114 *) If you start apache with the -S command line option it will dump
6115 out the parsed vhost settings. This is useful for folks trying
6116 to figure out what is wrong with their vhost configuration.
6117 (Other dumps may be added in the future.) [Dean Gaudet]
6119 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
6120 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
6123 *) Because /usr/local/apache is the default prefix the ``configure
6124 --compat'' option no longer has to set prefix, again. This way the
6125 --compat option honors a leading --prefix option. [Lars Eilebrecht]
6127 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
6128 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
6129 to avoid "discard const" warnings. [Ralf S. Engelschall]
6131 *) If a specific handler is set for a file yet the request still
6132 ends up being handled by the default handler, log an error
6133 message before handling it. This catches things such as trying
6134 to use SSIs without mod_include enabled. [Marc Slemko]
6136 *) Fix error logging for the startup case where ap_log_error() still uses
6137 stderr as the target. Now the default log level is honored here, too.
6138 [Ralf S. Engelschall]
6140 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
6141 long" errors when generating the MODULES entry for src/Makefile
6142 [Ben Hyde, Ralf S. Engelschall]
6144 *) Make sure src/Configure doesn't complain about the old directory
6145 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
6147 Changes with Apache 1.3b6
6149 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
6151 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
6152 interface via the similar but proprietary HP/UX shl_xxx-style system
6153 calls. [Ralf S. Engelschall]
6155 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
6156 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
6157 Make. [Ralf S. Engelschall]
6159 *) ++++ THE BIG SYMBOL RENAMING ++++
6160 To avoid symbol clashes with third-party code compiled into the server,
6161 we globally applied the prefix "ap_" to the following classes of
6163 - Apache provided general functions (e.g., ap_cpystrn)
6164 - Public API functions (e.g., palloc, bgets)
6165 - Private functions which we can't make static (because of
6166 cross-object usage) but should be (e.g., new_connection)
6167 For backward source compatibility a new header file named compat.h was
6168 created which provides defines for the old symbol names and can be used
6169 by third-party module authors.
6172 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
6173 problem under SVR4 is that there is no command flag to force the linker
6174 to export the global symbols of the httpd executable therewith they are
6175 available to the DSO's. Instead of problematic hacks like creating a
6176 dummy.so file (containing dummy references to all global symbols) the
6177 httpd binary is linked against, we use a clean trick stolen from Perl 5:
6178 Placing the Apache core code itself into a DSO library named libhttpd.so.
6179 This way the global symbols _HAVE_ to be exported and thus are available
6180 to any manually loaded DSO's under runtime. To reduce the impact to the
6181 user to null we go even further and create a stub httpd executable which
6182 automatically keeps track of the DSO library loading itself and thus
6183 hides the complete mechanism from the user. Although the generation of
6184 this DSO library is automatically triggered for platforms which
6185 essentially need it (mostly all SVR4-derivates) it can be also enabled
6186 manually via the Rule SHARED_CORE. This can be interesting in the future
6187 where we perhaps exploit this libhttpd.so mechanism for providing nifty
6188 features like graceful upgrades, or whatever.
6189 [Ralf S. Engelschall, Martin Kraemer]
6191 *) Build the libraries before building the rest of the tools. [Ben Hyde]
6193 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
6194 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
6195 conventions while "clean" removes only stuff created by "all" targets,
6196 "distclean" additionally removes the stuff from the configuration
6197 process. This way "make distclean" (hence the name) provides a fresh
6198 source tree as it was for distribution.
6199 [Ralf S. Engelschall]
6201 *) Allow top-level (APACI) Makefile to break on build errors
6202 the same way the src/ subtree Makefiles breaks on them by replacing the
6203 initial APACI sed-subdir-display-kludge with a more clean
6204 variable-passing-solution: variable SDP can optionally hold the subdir
6205 prefix which is consistently used for displaying the subdir movement.
6206 This way even the top-level Makefile can stop correctly on errors as the
6207 user expects. [Ralf S. Engelschall]
6209 *) Fixed ordering of argument checks for RewriteBase directive.
6210 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
6212 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
6213 indicating that a module is being compiled for dynamic loading. Also
6214 remove #define IS_MODULE from modules and add SHARED_MODULE define
6215 to the mak/dsp files. [Alexei Kosut]
6217 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
6218 since we are now logging APLOG_WARNING by default. [Roy Fielding]
6220 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
6222 *) Add documentation file and src/Configuration.tmpl entry for the
6223 experimental mod_mmap_static module. Because although it is and marked as
6224 an experimental one it is distributed and thus should be documented and
6225 prepared for configuration the same way as all others modules.
6226 [Ralf S. Engelschall]
6228 *) Add query (-q) option to apxs support tool to be able to manually query
6229 specific settings from apxs. This is needed for instance when you
6230 manually want to access Apache's header files and you need to assemble
6231 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
6232 [Ralf S. Engelschall]
6234 *) Now src/Configure uses a fallback strategy for the shared object support
6235 on platforms where no explicit information is available: If a Perl
6236 installation exists we ask it about its shared object support and if it's
6237 the dlopen-style one we shamelessly guess the compiler and linker flags
6238 for creating shared objects from Perls knowledge. Of course, the user is
6239 warning about what we are doing and informed that he should send us
6240 the guessed flags when they work. [Ralf S. Engelschall]
6242 *) Provide APACI --without-support option to be able to disable the build
6243 and installation of the support tools from the src/support/ area.
6244 Although its useful to have these installed per default we should provide
6245 a way to compile and install without them for backward-compatibility.
6246 [Ralf S. Engelschall]
6248 *) Add of the new APache eXtenSion (apxs) support tool for building and
6249 installing modules into an _already installed_ Apache package through the
6250 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
6251 this approach actually doesn't need the Apache source tree. The
6252 (APACI-installed) server package is enough, because this now includes the
6253 Apache C header files (PREFIX/include) and the new APXS tool
6254 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
6255 module authors to build their Apache modules _OUTSIDE_ the Apache source
6256 tree while avoiding them to fiddle around with the totally platform
6257 dependend way of compiling DSO files. The tool supports all ranges of
6258 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
6259 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
6260 on-the-fly generate a minimalistic Makefile and sample module for the
6261 first step to provide both a quick success event and to demonstrate the
6262 APXS mechanism to module authors. [Ralf S. Engelschall]
6264 *) Fix core dumps in use of CONNECT in proxy.
6265 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
6267 *) Modify the log directives in httpd.conf-dist files to use CustomLog
6268 so that users have examples of how CustomLog can be used.
6271 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
6272 the Apache distribution tree. Until Apache 1.3 there was no real
6273 out-of-the-box batch-capable build and installation procedure for the
6274 complete Apache package. This is now provided by a top-level "configure"
6275 script and a corresponding top-level "Makefile.tmpl" file. The goal is
6276 to provide a GNU Autoconf-style frontend which is capable to both drive
6277 the old src/Configure stuff in batch and additionally installs the
6278 package with a GNU-conforming directory layout. Any options from the old
6279 configuration scheme are available plus a lot of new options for flexibly
6280 customizing Apache. [Ralf S. Engelschall]
6282 *) The floating point ap_snprintf code wasn't threadsafe.
6283 Had to remove the HAVE_CVT macro in order to do threadsafe
6284 calling of the ?cvt() floating point routines. [Dean Gaudet]
6286 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
6288 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
6289 [Jim Jagielski] PR#1901
6291 *) BUG: Configure was using TCC and CC inconsistently. Make sure
6292 Configure knows which CC we are using. [Jim Jagielski]
6294 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
6295 was defined in a parent directory. [Lars Eilebrecht]
6297 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
6298 a generic printf-style routine that can call arbitrary output
6299 routines. Use this to replace http_bprintf.c. Add new routines
6300 psprintf(), pvsprintf() which allocate the exact amount of memory
6301 required for a string from a pool. Use psprintf() to clean up
6302 various bits of code which used ap_snprintf()/pstrdup().
6305 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
6306 ap_snprintf() has different semantics and formatting codes than
6307 snprintf(). [Dean Gaudet]
6309 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
6310 is necessary on at least Solaris where the /etc/rc?.d scripts
6311 are run with these signals ignored, and "SIG_IGN" settings are
6312 maintained across exec().

6337 properly marked for closure on fork().
6338 [Jürgen Keil <jk@tools.de>] PR#2000
6340 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6341 therefore not exposed to %2F -> '/' translations and 2) the request
6342 is a proxy request, so we're not dealing with a local resource anyway.
6343 Without this, the proxy would fail to work for any URL's with
6344 %2f in them (occurs quite often in
6345 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6347 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6349 *) Make the shared object compilation command more portable by avoiding
6350 the direct combination of `-c' & `-o' which is not honored by some
6351 compilers like UnixWare's cc. [Ralf S. Engelschall]
6353 *) WIN32: the proxy was creating filenames missing the last four
6354 characters. While this normally doesn't stop anything from
6355 working, it can result in extra collisions.

6359 code) from the already used FTP SIZE command to setup the Content-Length
6360 header if available. [Ralf S. Engelschall] PR#1183
6362 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6363 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6364 name was really too generic, added documentation for this directive to
6365 the mod_proxy.html and corrected the hyperlink to it in the

6368 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6369 faster [Martin Kraemer]
6371 *) Make Configure die when you give it an unknown command switch.
6374 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6375 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6376 and per default compiled support programs have manual pages - just to
6377 document our stuff a little bit more and to be able to do really
6378 Unix-like installations ;-) [Ralf S. Engelschall]
6380 *) Major cleanups to the Configure script to make it and its generated
6381 Makefiles again readable and maintainable: add SRCDIR option, removed
6382 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6383 generated sections, consequently added Makefile headers with inheritance
6384 information, added subdir movement messages for easier following where
6385 the build process currently stays (more verbose then standard Make, less
6386 verbose than GNU make), same style to comments in the Configure script,
6387 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6389 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6390 from the ZeusBench benchmarking program and can be used to determine the
6391 response performance of an Apache installation. This version is
6392 officially licensed with Zeus Technology, Ltd. See the license agreement

6394 [Ralf S. Engelschall]
6396 *) API: Various core functions that are definately not part of the API
6397 have been made static, and a few have been marked API_EXPORT. Still
6398 more have been marked CORE_EXPORT and are not intended for general
6399 use by modules. [Doug MacEachern, Dean Gaudet]
6401 *) mod_proxy was not clearing the Proxy-Connection header from
6402 requests; now it does. This did not violate any spec, however
6403 causes poor interactions when you are talking to remote proxies.

6412 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6414 *) Clean up some undocumented behavior of mod_setenvif related to
6415 "merging" two SetEnvIf directives when they match the same header
6416 and regex. Document that mod_setenvif will perform comparisons in
6417 the order they appear in the config file. Optimize mod_setenvif by
6418 doing more work at config time rather than at runtime.
6421 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6422 to allow for modules to overrule them and to reduce redefinition
6423 warnings [Jim Jagielski]
6425 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6428 *) Making the hard-coded cross-module function call mime_find_ct() (from

6430 checking is really called even for proxy requests except for URLs with
6431 HTTP schemes (because there we can optimize by not running the type
6432 checking hooks due to the fact that the proxy gets the MIME Content-type
6433 from the remote host later). This change cleans up mod_mime by removing
6434 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6435 especially unbundles mod_proxy and mod_mime. This way they both now can
6436 be compiled as shared objects and are no longer tied together.
6437 [Ralf S. Engelschall]
6439 *) util.c cleanup and speedup. [Dean Gaudet]
6441 *) API: Clarification, pstrndup() will always copy n bytes of the source
6442 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6444 *) Mark module command_rec and handler_rec structures const so that they
6445 end up in the read-only data section (and are friendlier to systems
6446 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6448 *) Add check to the "Port" directive to make sure the specified
6449 port is in the appropriate range. [Ben Hyde]
6451 *) Performance improvements to invoke_handler().
6452 [Dmitry Khrustalev <dima@bog.msu.su>]
6454 *) Added support for building shared objects even for library-style modules
6455 (which are built from more than one object file). This now provides the
6456 ability to build mod_proxy as a shared object module. Additionally
6457 modules like mod_example are now also supported for shared object
6458 building because the generated Makefiles now no longer assume there is at
6459 least one statically linked module. [Ralf S. Engelschall]
6461 *) API: Clarify usage of content_type, handler, content_encoding,
6462 content_language and content_languages fields in request_rec. They
6463 must always be lowercased; and the strings pointed to shouldn't
6464 be modified (you must copy them to modify them). Fix a few bugs
6465 related to this. [Dean Gaudet]
6467 *) API: Clarification: except for RAW_ARGS, all command handlers can
6468 treat the char * parameters as permanent, and modifiable. There
6469 is no need to pstrdup() them. Clean up some needless pstrdup().
6472 *) Now mod_so keeps track of which module shared objects with which names
6473 are loaded and thus avoids multiple loading and unloading and irritating
6474 error_log messages. [Ralf S. Engelschall]
6476 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6477 environment variable in the apache core. But that tweaking interferes
6478 with mod_setenv. So don't tweak if the user has specified an explicit
6479 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6481 *) rputs() did not calculate r->sent_bodyct properly.
6482 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6484 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6485 name, or left unset if this value is unavailable. Apache was setting
6486 it to the IP address when unavailable.
6487 [Tony Finch <fanf@demon.net>] PR#1925
6489 *) Various improvements to the configuration and build support for compiling
6490 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6491 OSF1 support with GCC and vendor compilers was added. This way shared
6492 object support is now provided out-of-the-box for FreeBSD, Linux,
6493 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6494 [Ralf S. Engelschall]
6496 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6497 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6498 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6500 *) Fix one more special locking problem for RewriteMap programs in
6501 mod_rewrite: According to the documentation of flock(), "Locks are on
6502 files, not file descriptors. That is, file descriptors duplicated
6503 through dup(2) or fork(2) do not result in multiple instances of a lock,
6504 but rather multiple references to a single lock. If a process holding a
6505 lock on a file forks and the child explicitly unlocks the file, the
6506 parent will lose its lock.". To overcome this we have to make sure the
6507 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6508 the case by opening it in the child_init instead of the module_init API
6509 hook. [Ralf S. Engelschall] PR#1029
6511 *) Change to Location and LocationMatch semantics. LocationMatch no
6512 longer lets a single slash match multiple adjacent slashes in the
6513 URL. This change is for consistency with RewriteRule and
6514 AliasMatch. Multiple slashes have meaning in URLs that they do
6515 not have in (some) filesystems. Location on the other hand can
6516 be considered a shorthand for a more complicated regex, and it
6517 does match multiple slashes with a single slash -- which is
6518 also consistent with the Alias directive.
6519 [Dean Gaudet] related PR#1440
6521 *) Fix bug with mod_mime_magic causing certain files, including files
6522 of length 0, to result in no response from the server.
6525 *) The Configure script now generates src/include/ap_config.h which
6526 contains the set of defines used when Apache is compiled on a platform.
6527 This file can then be included by external modules before including
6528 any Apache header files in case they are being built separately from
6529 Apache. Along with this change, a couple of minor changes were
6530 made to make Apache's #defines coexist peacefully with any autoconf
6531 defines an external module might have. [Rasmus Lerdorf]
6533 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6534 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6535 chance by the API to initialize its per-server configuration and thus
6536 receives the wrong one from the main server. This is now avoided by
6537 remembering the server together with the config structure while
6538 configuring and later assuming there is no config when we see a
6539 difference between the remembered server and the one calling us.
6540 [Ralf S. Engelschall] PR#1790
6542 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6543 is automatically disabled under configure time when the dbm_xxx functions
6544 are not available. Second, two heavy source code errors in the DBM
6545 support code were fixed. This makes DBM RewriteMap's usable again after
6546 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6548 *) Now all configuration files support Unix-style line-continuation via
6549 the trailing backslash ("\") character. This enables us to write down
6550 complex or just very long directives in a more readable way. The
6551 backslash character has to be really the last character before the
6552 newline and it has not been prefixed by another (escaping) backslash.
6553 [Ralf S. Engelschall]
6555 *) When using ProxyPass the ?querystring was not passed correctly.
6556 [Joel Truher <truher@wired.com>]
6558 *) To deal with modules being compiled and [dynamically] linked
6559 at a different time from the core, the SERVER_VERSION and
6560 SERVER_BUILT symbols have been abstracted through the new
6561 API routines apapi_get_server_version() and apapi_get_server_built().
6564 *) WIN32: Preserve trailing slash in canonical path (and hence
6565 in PATH_INFO). [Paul Sutton, Ben Laurie]
6567 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6568 depending on the rev of Solaris and what mixture of modules
6569 are in use. So it has been disabled, and Solaris is back to
6570 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6571 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6572 up static content only servers. Or it may fail unpredictably.
6573 [Dean Gaudet] PR#1779, 1854, 1904
6575 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6578 *) API: Rewrite of absoluteURI handling, and in particular how
6579 absoluteURIs match vhosts. Unless a request is a proxy request, a
6580 "http://host" url is treated as if a similar "Host:" header had been
6581 supplied. This change was made to support future HTTP/1.x protocols
6582 which may require clients to send absoluteURIs for all requests.
6584 In order to achieve this change subtle changes were made to the API. In a
6585 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6586 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6587 by the core, modules must set it during the post_read_request or
6588 translate_names phase.
6590 Plus changes to the virtualhost test suite for absoluteURI testing.
6592 This fixes several bugs with the proxy proxying requests to vhosts
6593 managed by the same httpd.
6596 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6597 code from mod_rewrite. The vhost matching is now performed by a
6598 globally available function matches_request_vhost(). [Dean Gaudet]
6600 *) Reduce memory usage, and speed up ServerAlias support. As a
6601 side-effect users can list multiple ServerAlias directives
6602 and they're all considered.

6609 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
6611 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
6612 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
6614 *) API: A new source module main/util_uri.c; It contains a routine
6615 parse_uri_components() and friends which breaks a URI into its component
6616 parts. These parts are stored in a uri_components structure called
6617 parsed_uri within each request_rec, and are available to all modules.
6618 Additionally, an unparse routine is supplied which re-assembles the URI
6619 components back to an URI, optionally hiding the username:password@ part
6620 from ftp proxy requests, and other useful routines. Within the structure,
6621 you find on a ready-for-use basis:
6622 scheme; /* scheme ("http"/"ftp"/...) */
6623 hostinfo; /* combined [user[:password]@]host[:port] */
6624 user; /* user name, as in http://user:passwd@host:port/ */
6625 password; /* password, as in http://user:passwd@host:port/ */
6626 hostname; /* hostname from URI (or from Host: header) */
6627 port_str; /* port string (integer representation is in "port") */
6628 path; /* the request path (or "/" if only scheme://host was given) */
6629 query; /* Everything after a '?' in the path, if present */
6630 fragment; /* Trailing "#fragment" string, if present */
6631 This is meant to serve as the platform for *BIG* savings in
6632 code complexity for the proxy module (and maybe the vhost logic).
6635 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6636 ${map:key}) available for all location where a string is created in
6637 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6638 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6639 possible expansions are consequently usable at all string creation
6640 locations. [Ralf S. Engelschall]
6642 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6643 and not 1) and the per-virtual-server merging of directives. Now all
6644 directives except `RewriteEngine' and `RewriteOption' are either
6645 completely overridden (default) or completely inherited (when
6646 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
6648 *) Fix `RewriteMap' program lookup in situations where such maps are
6649 defined but disabled (`RewriteEngine off') in per-server context.
6650 [Ralf S. Engelschall] PR#1431
6652 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6653 server to bind to port 0 rather than 80. [Dean Gaudet]
6655 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6656 (like SunOS and FreeBSD) which don't accept the locking of pipes
6657 directly. A new directive RewriteLock is introduced which can be used to
6658 setup a separate locking file which then is used for synchronization.

6673 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6674 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6676 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6677 type but with a special post-processing for the looked-up value: It
6678 parses it into alternatives according to `|' chars and then only one
6679 particular alternative is chosen randomly (this is an essential
6680 functionality needed for balancing between backend-servers when using
6681 Apache as a Reverse Proxy. The looked up value here is a list of
6682 servers). Second, `int' with the built-in maps named `tolower' and
6683 `toupper' which can be used to map URL parts to a fixed case (this is an
6684 essential feature to fix the case of server names when doing mass
6685 virtual-hosting with the help of mod_rewrite instead of using
6686 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6687 Jay Soffian <jay@cimedia.com>] PR#1631
6689 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6690 This directive lets Apache adjust the URL in Location-headers on HTTP
6691 redirect responses sent by the remote server. This way the virtually
6692 mapped area is no longer left on redirects and thus by-passed which is
6693 especially essential when running Apache as a reverse proxy.

6808 now ignores a leading x- when comparing encodings. It also
6809 preserves the encoding the client requests (for example if
6810 it requests x-gzip, then Apache will respond with x-gzip
6811 in the Content-Encoding header).

6841 *) Yet another rearrangement of the source tree.. now all the common
6842 header files are in the src/include directory. The -Imain -Iap
6843 references in Makefiles have been changed to the simpler -Iinclude
6844 instead. In addition to simplifying the build a little bit, this
6845 also makes it clear when a module is referencing something in a
6846 other than kosher manner (e.g., the proxy including mod_mime.h).
6847 Module-private header files (the proxy, mod_mime, the regex library,
6848 and mod_rewrite) have not been moved to src/include; nor have

6878 *) mod_unique_id was erroneously generating a second unique id when
6879 an internal redirect occured. Such redirects occur, for example,
6880 when processing a DirectoryIndex match. [Dean Gaudet]
6882 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6883 of the key and value. But in many cases this is not required
6884 because the key/value is a constant, or the value has been built
6885 by pstrcat() or other similar means. New routines table_addn,
6886 table_mergen, and table_setn have been added to the API, these
6887 routines do not pstrdup() their arguments. The core code and
6888 standard modules were changed to take advantage of these routines.
6889 The resulting server is up to 20% faster in some situations.
6891 Note that it is easy to get code subtly wrong if you pass a key/value
6892 which is in a pool other than the pool of the table. The only
6893 safe thing to do is to pass key/values which are in the pool of
6894 the table, or in one of the ancestors of the pool of the table.
6895 i.e. if the table is part of a subrequest, a value from the main
6896 request's pool is OK since the subrequest pool is a sub_pool of the
6897 main request's pool (and therefore has a lifespan at most as long as
6898 the main pool). There is debugging code which can detect improper
6899 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

6904 Update documentation to reflect the code -- if there's no
6905 MimeMagicFile directive then the module is not enabled.
6908 *) PORT: Some older *nix dialects cannot automatically start scripts
6909 which begin with a #! interpreter line (the shell starts the scripts
6910 appropriately on these platforms). Apache now supports starting of

6917 some standard modules got this wrong. By changing the definition
6918 to "typedef struct table table" module authors will receive compile
6919 time warnings that they're doing the wrong thing. This change
6920 facilitates future changes with more sophisticated table

6930 *) For clarity the following compile time definition was changed:
6932 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6934 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6935 and not be a general notice that the OS has mmap(). Now the
6936 HAVE_MMAP/SHMGET #defines strictly are informational that the
6937 OS has that method of shared memory; the type to use for
6938 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6939 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6940 determine if shared memory is available and allows Apache
6941 to determine the best method to use for the scoreboard.
6944 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6945 as do various earlier versions. It should be safe on all versions.
6946 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
6947 the slack code. A few other cleanups for Unixware.
6948 [Tom Hughes <thh@cyberscience.com>] PR#1082, PR#1282, PR#1499, PR#1553
6950 *) PORT: A/UX can handle single-listen accepts without mutex
6951 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
6953 *) When die() happens we need to eat any request body if one exists.
6954 Otherwise we can't continue with a keepalive session. This shows up
6955 as a POST problem with MSIE 4.0, typically against pages which are
6956 authenticated. [Roy Fielding] PR#1399
6958 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
6959 header will be passed to CGIs. This is generally a security hole, so
6960 it's not a default. [Marc Slemko] PR#549
6962 *) Fix Y2K problem with date printing in suexec log.
6963 [Paul Eggert <eggert@twinsun.com>] PR#1343
6965 *) WIN32 deserves a pid file. [Ben Hyde]
6967 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
6969 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
6970 The choice of flock vs. fcntl was made based on timings which showed that
6971 even on non-NFS, non-exported filesystems fcntl() was an order of
6972 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
6973 that single socket users will see no difference. [Dean Gaudet] PR#467
6975 *) "File does not exist" error message was erroneously including the
6976 errno. [Marc Slemko]
6978 *) Improve the warning message generated when a client drops the
6979 connection (hits stop button, etc.) during a send. [Roy Fielding]
6981 *) Defining GPROF will disable profiling in the parent and enable it
6982 in the children. If you're profiling under Linux this is pretty much
6983 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
6985 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
6988 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
6989 gcc functionality. Work around it.
6990 [Keith Severson <keith@sssd.navy.mil>] PR#1613
6992 *) Some linkers complain when .o files contain no functions.
6993 [Keith Severson <keith@sssd.navy.mil>] PR#1614
6995 *) Some const declarations in mod_imap.c that were added for debugging
6996 purposes caused some compilers heartburn without adding any
6997 significant value, so they've been removed. [Ken Coar]
6999 *) The src/main/*.h header files have had #ifndef wrappers added to
7000 insulate them against duplicate calls if they get included through
7001 multiple paths (e.g., in .c files as well as other .h files).
7004 *) The libap routines now have a header file for their prototypes,
7005 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
7007 *) mod_autoindex with a plaintext header file would emit the <PRE>
7008 start-tag before the HTML preamble, rather than after the preamble
7009 but before the header file contents. [John Van Essen <jve@gamers.org>]
7012 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7013 only an issue on systems without a MAXDNAME define or where
7014 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7016 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7017 is used to read various types of files such as htaccess and
7018 htpasswd files. [Marc Slemko]
7020 *) SECURITY: Ensure that the buffer returned by ht_time is always
7021 properly null terminated. [Marc Slemko]
7023 *) The "Connection" header could be sent back with multiple "close"
7024 tokens. Not an error, but a waste.
7025 [Ronald.Tschalaer@psi.ch] PR#1683
7027 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
7028 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
7030 *) "basic" auth needs a case-insensitive comparison.
7031 [Ronald.Tschalaer@psi.ch] PR#1666
7033 *) For maximum portability, the environment passed to CGIs should
7034 only contain variables whose names match the regex
7035 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
7036 underscores over any character outside the regex. This
7037 affects HTTP_* variables, in a way that should be backward
7038 compatible for all the standard headers; and affects variables
7039 set with SetEnv/BrowserMatch and similar directives.
7042 *) mod_speling returned incorrect HREF's when an ambigous match
7043 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
7044 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
7046 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
7047 (the Siemens BS2000/OSD family) in the POSIX subsystem
7050 *) PORT: Fix problem killing children when terminating. Allow ^C
7051 to shut down the server. [Brian Havard]
7053 *) pstrdup() is implicit in calls to table_* functions, so there's
7054 no need to do it before calling. Clean up a few cases.
7055 [Marc Slemko, Dean Gaudet]
7057 *) new -C and -c command line arguments
7059 -C "directive" : process directive before reading config files
7060 -c "directive" : process directive after reading config files
7062 httpd -C "PerlModule Apache::httpd_conf"
7063 [Doug MacEachern, Martin Kraemer]
7065 *) WIN32: Fix the execution of CGIs that are scripts and called
7066 with path info that does not have an '=' in.
7067 (eg. http://server/cgi-bin/printenv?foobar)
7068 [Marc Slemko] PR#1591
7070 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to
7071 mess with fake filenames. This fixes proxy caching on
7074 *) SECURITY: General mod_include cleanup, including fixing several
7075 possible buffer overflows and a possible infinite loop.
7076 [Dean Gaudet, Marc Slemko]
7078 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7079 including fixing a possible buffer overflow. [Dean Gaudet]
7081 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
7082 (connections are not dropped). Code can handle graceful restarts
7083 (but there is as yet no way to signal this to Apache). Various
7084 other cleanups. [Paul Sutton]
7086 *) The aplog_error changes specific to 1.3 introduced a buffer
7087 overrun in the (now legacy) log_printf function. Fixed.
7090 *) mod_digest didn't properly deal with proxy authentication. It
7091 also lacked a case-insensitive comparision of the "Digest"
7092 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
7094 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
7096 *) A few cleanups in mod_info to make it thread-safe, and remove an
7097 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
7099 *) no2slash() was O(n^2) in the length of the input. Make it O(n).
7102 *) API: migration from strncpy() to our "enhanced" version called
7103 ap_cpystrn() for performance and functionality reasons.
7104 Located in libap.a. [Jim Jagielski]
7106 *) table_set() and table_unset() did not deal correctly with
7107 multiple occurrences of the same key.
7108 [Stephen Scheck <sscheck@infonex.net>, Ben Laurie] PR#1604
7110 *) The AuthName must now be enclosed in quotes if it is to contain
7111 spaces. [Ken Coar] PR#1195
7113 *) API: new function: ap_escape_quotes(). [Ken Coar] PR#1195
7115 *) WIN32: Work around optimiser bug that killed ISAPI in release
7116 versions. [Ben Laurie] PR#1533
7118 *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]
7120 *) Interim (slow) fix for p->sub_pool critical sections in
7121 alloc.c (affects win32 only). [Ben Hyde]
7123 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
7125 *) send_fd_length() did not calculate total_bytes_sent properly.
7126 [Ben Reser <breser@regnow.com>] PR#1366
7128 *) The bputc() macro was not properly integrated with the chunking
7129 code; in many cases modules using bputc() could cause completely
7130 bogus chunked output. (Typically this will show up as problems
7131 with Internet Explorer 4.0 reading a page, but other browsers
7132 having no problem.) [Dean Gaudet]
7134 *) Create LARGE_WRITE_THRESHOLD define which determines how many
7135 bytes have to be supplied to bwrite() before it will consider
7136 doing a writev() to assemble multiple buffers in one system
7137 call. This is critical for modules such as mod_include,
7138 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
7139 strings in some cases. The result would be extra effort
7140 setting up writev(), and in many cases extra effort building
7141 chunks. The default is 31, it can be overriden at compile
7144 *) Move the gid switching code into the child so that log files
7145 and pid files are opened with the root gid.
7146 [Gregory A Lundberg <lundberg@vr.net>]
7148 *) WIN32: Check for binaries by looking for the executable header
7149 instead of counting control characters.
7150 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
7152 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
7153 so the functionality is available to applications other than the
7154 server itself (like the src/support tools). [Ken Coar]
7156 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
7157 the libap consolidation work. [Ken Coar]
7159 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
7160 useful, and isn't what the standards require. Now it returns 0
7161 and writes nothing. [Dean Gaudet]
7163 *) When an error occurs in fcntl() locking suggest the user look up
7164 the docs for LockFile. [Dean Gaudet]
7166 *) Eliminate some dead code from writev_it_all().
7167 [Igor Tatarinov <tatarino@prairie.NoDak.edu>]
7169 *) mod_autoindex had an fread() without checking the result code.
7170 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"
7171 (note the missing closing paren) properly. [Dean Gaudet]
7173 *) It appears the "257th byte" bug (see
7174 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7175 at the 256th byte as well. Fixed. [Dean Gaudet]
7177 *) PORT: Fix mod_mime_magic under OS/2, no support for block devices.
7180 *) Fix memory corruption caused by allocating auth usernames in the
7181 wrong pool. [Dean Gaudet] PR#1500
7183 *) Fix an off-by-1, and an unterminated string error in
7184 mod_mime_magic. [Dean Gaudet]
7186 *) Fix a potential SEGV problem in mod_negotiation when dealing
7187 with type-maps. [Dean Gaudet]
7189 *) Better glibc support under Linux. [Dean Gaudet] PR#1542
7191 *) "RedirectMatch gone /" would cause a SIGSEGV. [Dean Gaudet] PR#1319
7193 *) WIN32: avoid overflows during file canonicalisations.
7194 [malcolm@mgdev.demon.co.uk] PR#1378
7196 *) WIN32: set_file_slot() didn't detect absolute paths. [Ben Laurie]
7199 *) WIN32: mod_status display header didn't match fields. [Ben Laurie]
7201 *) The pthread_mutex_* functions return an error code, and don't
7202 set errno. [Igor Tatarinov <tatarino@prairie.NoDak.edu>]
7204 *) WIN32: Allow spaces to prefix the interpreter in #! lines.
7205 [Ben Laurie] PR#1101
7207 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523
7209 *) proxy_ftp: the directory listings generated by the proxy ftp module
7210 now have a title in which the path components are clickable and allow
7211 quick navigation to the clicked-on directory on the currently listed
7212 ftp server. This also fixes a bug where the ".." directory links would
7213 sometimes refer to the wrong directory. [Martin Kraemer]
7215 *) WIN32: Allocate the correct amount of memory for the scoreboard.
7218 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]
7221 *) Fix problems with timeouts in inetd mode and -X mode. [Dean Gaudet]
7223 *) Fix the spurious "(0)unknown error: mmap_handler: mmap failed"
7224 error messages. [Ben Hyde]
7226 Changes with Apache 1.3b3
7228 *) WIN32: Work around brain-damaged spawn calls that can't deal
7229 with spaces and slashes. [Ben Laurie]
7231 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
7232 The problem was that certain undocumented environment variables
7233 needed for sockets to work under Win32 were not being passed.
7234 [Frank Faubert <frank@sane.com>]
7236 *) Add a "-V" command line flag to the httpd binary. This
7237 flag shows some of the defines that Apache was compiled with.
7238 It is useful for debugging purposes. [Martin Kraemer]
7240 *) Start separating the ap_*() routines into their own library, so they
7241 can be used by items in src/support among other things.
7242 [Ken Coar] PR#512, 905, 1252, 1308
7244 *) Give a more informative error when no AuthType is set.
7247 *) Remove strtoul() use from mod_proxy because it isn't available
7248 on all platforms. [Marc Slemko] PR#1214
7250 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
7251 This turns out to be a bug in Winsock - select() doesn't always
7252 return the correct status. [Ben Laurie]
7254 *) Directives owned by http_core can now use the new check_cmd_context()
7255 routine to ensure that they're not being used within a container
7256 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
7258 *) PORT: Recent changes made it necessary to add explicit prototype
7259 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
7261 *) It was necessary to distinguish between resources which are
7262 allocated in the parent, for cleanup in the parent, and resources
7263 which are allocated in each child, for cleanup in each child.
7264 A new pool was created which is passed to the module child_init
7265 and child_exit functions; modules are free to register per-child
7266 cleanups there. This fixes a bug with reliable piped logs.
7269 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
7270 unless it was also doing FancyIndexes, but it displayed the
7271 HeaderName file at the top under all circumstances. It now shows
7272 the ReadmeName file for simple indices, too, as it should.
7275 *) http_core was mmap()ing even in cases where it wasn't going to
7276 read the file. [Ben Hyde <bhyde@gensym.com>]
7278 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
7279 Now the rewriting engine (the heart of mod_rewrite) is organized more
7280 straight-forward, first time well documented and reduced to the really
7281 essential parts. All redundant cases were stripped off and processing now
7282 is the same for both per-server and per-directory context with only a
7283 minimum difference (the prefix stripping in per-dir context). As a
7284 side-effect some subtle restrictions and two recently discovered problems
7285 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
7286 context and restrictions on the substitution URL on redirects.
7287 Additionally some minor source cleanups were done.
7288 [Ralf S. Engelschall]
7290 *) Lars Eilebrecht wrote a whole new set of Apache Vhost Internals
7291 documentation, examples, explanations and caveats. They live in a new
7292 subdirectory htdocs/manual/vhost/. [Lars Eilebrecht <sfx@unix-ag.org>]
7294 *) If ap_slack fails to allocate above the low slack line it's a good
7295 indication that further problems will occur; it's a better indication
7296 than many external libraries give us when we actually run out of
7297 descriptors. So report it to the user once per restart.

7449 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7450 rudimentary memory debugger which can be used on live servers with
7451 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7452 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7453 and free() for each object. This is far more expensive and should
7454 only be used for testing with tools such as Electric Fence and
7455 Purify. See main/alloc.c for more details. [Dean Gaudet]

7461 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7462 From a given ip:port, regardless what the Host: header is, you can
7463 only reach the vhosts defined on that ip:port. The precedence of
7464 vhosts was reversed to match other precedences in the config --
7465 the earlier vhosts override the later vhosts. All vhost matching was
7466 moved into http_vhost.[ch]. [Dean Gaudet]
7468 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7469 be used for whatever reason is appropriate (i.e. format() warnings
7470 for printf style functions). Both are enabled only with
7471 gcc >= 2.7.x (so that we have fewer support issues with older
7472 versions). [Dean Gaudet]
7474 *) Fix support for Proxy Authentication (we were testing the response
7475 status too early). [Marc Slemko]
7477 *) CoreDumpDirectory directive directs where the core file is
7478 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7479 received. [Marc Slemko, Dean Gaudet]
7481 *) PORT: Support for Atari MINT.
7482 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7484 *) When booting, apache will now detach itself from stdin, stdout,
7485 and stderr. stderr will not be detached until after the config
7486 files have been read so you will be able to see initial error
7487 messages. After that all errors are logged in the error_log.
7488 This makes it more convenient to start apache via rsh, ssh,
7489 or crontabs. [Dean Gaudet] PR#523
7491 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7492 Also removed the auto-generated link to www.apache.org that was the
7493 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7495 *) send_fb would not detect aborted connections in some situations.
7498 *) mod_include would use uninitialized data when parsing certain
7499 expressions involving && and ||. [Brian Slesinsky] PR#1139
7501 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7503 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7505 *) mod_autoindex improperly counted &escapes; as more than one
7506 character in the description. It also improperly truncated
7507 descriptions that were exactly the maximum length.
7510 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7511 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7514 *) mod_include now uses symbolic names to check for request success
7515 and return HTTP errors, and correctly handles all types of
7516 redirections (previously it only did temporary redirect correctly).
7517 [Ken Coar, Roy Fielding]
7519 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7520 r->filename. Since those two are meant to be in sync with each other
7521 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7523 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7524 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7526 *) Inetd mode (which is buggy) uses timeouts without having setup the
7527 jmpbuffer. [Dean Gaudet] PR#1064
7529 *) Work around problem under Linux where a child will start looping
7530 reporting a select error over and over.
7531 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7533 *) Fixed error in proxy_util.c when looping through multiple host IP
7534 addresses. [Lars Eilebrecht] PR#974
7536 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7537 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7538 bytes before writing, but it will never split a log entry across a
7539 buffer boundary. [Dean Gaudet]
7541 *) API: the short_score record has been split into two pieces, one which
7542 the parent writes on, and one which the child writes on. As part of
7543 this change the get_scoreboard_info() function was removed, and
7544 scoreboard_image was exported. This change fixes a race condition
7545 in file based scoreboard systems, and speeds up changes involving the
7546 scoreboard in earlier 1.3 development. [Dean Gaudet]
7548 *) API: New register_other_child() API (see http_main.h) which allows
7549 modules to register children with the parent for maintenance. It
7550 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7552 *) API: New piped_log API (see http_log.h) which implements piped logs,
7553 and will use register_other_child to implement reliable piped logs
7554 when it is available. The reliable piped logs part can be disabled
7555 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7556 logs is only available on Unix. [Dean Gaudet]
7558 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7559 meets_conditions(). This allows conditional HTTP selection to be
7560 handled separately from the storing of the header fields, and provides
7561 the ability for CGIs to set their own ETags for conditional checking.
7562 [Ken Coar, Roy Fielding] PR#895
7564 *) Changes to mod_log_config to allow naming of format strings.
7565 Format nicknames are defined with "LogFormat fmt nickname", and can
7566 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7569 *) New module, "mod_speling", which can help find files even when
7570 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7572 *) API: New function child_terminate() triggers the child process to
7573 exit, while allowing the child finish what it needs to for the
7574 current request first.
7575 [Doug MacEachern, Alexei Kosut]
7577 *) Windows now defaults to using full status reports with mod_status.
7578 [Alexei Kosut] PR #1094
7580 *) *Really* disable all mod_rewrite operations if the engine is off.
7581 Some things (like RewriteMaps) were checked/performed even if they
7582 weren't supposed to be. [Ken Coar] PR #991
7584 *) Implement a new timer scheme which eliminates the need to call alarm() all
7585 the time. Instead a counter in the scoreboard for each child is used to
7586 show when the child has made forward progress. The parent samples this
7587 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7588 progress has been made in the timeout period. This reduces the static
7589 request best-case syscall count to 22 from 29. This scheme is only
7590 used by systems with memory-based scoreboards. [Dean Gaudet]
7592 *) The proxy now properly handles CONNECT requests which are sent
7593 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7595 *) A script called apachectl has been added to the support
7596 directory. This script allows you to do things such as
7597 "apachectl start" and "apachectl restart" from the command
7600 *) Modules and core routines are now put into libraries, which
7601 simplifies the link line tremendously (among other advantages).
7604 *) Some of the MD5 names defined in Apache have been renamed to have
7605 an `ap_' prefix to avoid conflicts with routines supplied by
7606 external libraries. [Ken Coar]
7608 *) Removal of mod_auth_msql.c from the distribution. There are many
7609 other options for databases today. Rather than offer one option,
7610 offer none at this time. mod_auth_msql and other SQL database
7611 authentication modules can be found at the Apache Module Registry.
7612 http://modules.apache.org/ It would be nice to offer a generic
7613 mod_auth_sql option in the near future.
7615 *) PORT: BeOS support added [Alexei Kosut]
7617 *) Configure no longer accepts the -make option, since it creates
7618 Makefile on the fly based on Makefile.tmpl and Configuration.
7620 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7621 of forcibly killing off all its processes and exiting without
7622 cleaning up. [Alexei Kosut]
7624 *) API: A new field in the request_rec, r->mtime, has been added to
7625 avoid gratuitous parsing of date strings. It is intended to hold
7626 the last-modified date of the resource (if applicable). An
7627 update_mtime() routine has also been added to advance it if
7628 appropriate. [Roy Fielding, Ken Coar]
7630 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7631 deny access to the directory with a HTTP_FORBIDDEN. The previous
7632 behavior was to ignore the htaccess file if it could not be read.
7633 This change may make some setups with unreadable htaccess files
7634 stop working. [Marc Slemko] PR#817
7636 *) Add aplog_error() providing a mechanism to define levels of
7637 verbosity to the server error logging. This addition also provides
7638 the ability to log errors using syslogd. Error logging is configurable
7639 on a per-server basis using the LogLevel directive. Conversion
7640 of log_*() in progress. [Randy Terbush]
7642 *) Further enhance aplog_error() to not log filename, line number, and
7643 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7645 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7646 converted to long ones. Backslashes are converted to forward
7647 slashes. Case is converted to lower. Parts of URLs that do not
7648 correspond to files are left completely alone. [Ben Laurie]
7650 *) PORT: 2 new OSs added to the list of ports:
7651 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7652 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7654 *) Add the server version (SERVER_VERSION macro) to the "server
7655 configured and running" entry in the error_log. Also build an
7656 object file at link-time that contains the current time
7657 (SERVER_BUILT global const char[]), and include that in the
7660 *) Set r->headers_out when sending responses from the proxy.
7661 This fixes things such as the logging of headers sent from
7662 the proxy. [Marc Slemko] PR#659
7664 *) support/httpd_monitor is no longer distributed because the
7665 scoreboard should not be file based if at all possible. Use
7666 mod_status to see current server snapshot.
7668 *) (set_file_slot): New function, allowing auth directives to be
7669 independent of the server root, so the server documents can be
7670 moved to a different directory or machine more easily.
7671 [David J. MacKenzie]
7673 *) If no TransferLog is given explicitly, decline
7674 to log. This supports coexistence with other logging modules,
7675 such as the custom one that UUNET uses. [David J. MacKenzie]
7677 *) Check for titles in server-parsed HTML files.
7678 Ignore leading newlines and returns in titles. The old behavior
7679 of replacing a newline after <title> with a space causes the
7680 title to be misaligned in the listing. [David J. MacKenzie]
7682 *) Change mod_cern_meta to be configurable on a per-directory basis.
7683 [David J. MacKenzie]
7685 *) Add 'Include' directive to allow inclusion of configuration
7686 files within configuration files. [Randy Terbush]
7688 *) Proxy errors on connect() are logged to the error_log (nothing
7689 new); now they include the IP address and port that failed
7690 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7692 *) Various architectures now define USE_MMAP_FILES which causes
7693 the server to use mmap() for static files. There are two
7694 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7695 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7696 number of bytes written in one cycle from a single mmap()d object,
7697 default 32768). [Dean Gaudet]
7699 *) API: Added post_read_request API phase which is run right after reading
7700 the request from a client, or right after an internal redirect. It is
7701 useful for modules setting environment variables that depend only on
7702 the headers/contents of the request. It does not run during subrequests
7703 because subrequests inherit pretty much everything from the main
7704 request. [Dean Gaudet]
7706 *) Added mod_unique_id which is used to generate a unique identifier for
7707 each hit, available in the environment variable UNIQUE_ID.
7710 *) init_modules is now called after the error logs have been opened. This
7711 allows modules to emit information messages into the error logs.
7714 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7715 information for case where proxy module is not available. [Marc Slemko]
7717 *) PORT: Apache has need for mutexes to serialize its children around
7718 accept. In prior versions either fcntl file locking or flock file
7719 locking were used. The method is chosen by the definition of
7720 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7721 and FLOCK for flock(). New options have been added:
7722 - SYSVSEM to use System V style semaphores
7723 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7724 - USLOCK to use IRIX uslock
7725 Based on timing various techniques, the following changes were made
7727 - Linux 2.x uses flock instead of fcntl
7728 - Solaris 2.x uses pthreads
7729 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7730 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7731 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7732 Martijn Koster <m.koster@pobox.com>]
7734 *) PORT: The semantics of accept/select make it very desirable to use
7735 mutexes to serialize accept when multiple Listens are in use. But
7736 in the case where only a single socket is open it is sometimes
7737 redundant to serialize accept(). Not all unixes do a good job with
7738 potentially dozens of children blocked on accept() on the same
7739 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7740 the server will avoid serialization when listening on only one socket,
7741 and use serialization when listening on multiple sockets.
7742 [Dean Gaudet] PR#467
7744 *) Configure changes: TestLib replaced by TestCompile, which has
7745 some additional capability (such as doing a sanity check of
7746 the compiler and flags selected); the version of Solaris is now
7747 available via the #define value of SOLARIS2; IRIX n32bit libs
7748 now supported and selectable by new Configuration Rule: IRIXN32;
7749 We no longer default to -O2 optimization. [Jim Jagielski]
7751 *) Updated Configure: Configuration now uses AddModule to specify
7752 module source or binary file location, relative to src directory.
7753 Modules can be dropped into modules/extra, or in their own
7754 directory, and modules can come with a Makefile or Configure can
7755 create one. Modules can add compiler or library information to
7756 generated Makefiles. [Paul Sutton]
7758 *) Source core re-organisation: distributed modules are now in
7759 modules/standard. All other source code is in main. OS-specific
7760 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7762 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7765 *) Fix another long-standing bug in sub_req_lookup_file where it would
7766 happily skip past access checks on subdirectories looked up with
7767 relative paths. (It's used by mod_dir, mod_negotiation,
7768 and mod_include.) [Dean Gaudet]
7770 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7771 N is the number of <Directory> sections, and M is the number of
7772 components in the filename of an object.
7774 To achieve this optimization the following config changes were made:
7775 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7776 <Files>s, and <Location>s now treat a slash as a special
7777 character. For example "/home/*/public_html" previously would
7778 match "/home/a/andrew/public_html", now it only matches things
7779 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7780 - It's possible now to use [] wildcarding in <Directory>, <Files>
7782 - Regex <Directory>s are applied after all non-regex <Directory>s.
7786 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7787 and corrupted paths. [Dean Gaudet]
7789 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7790 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7791 be accessed now via backreferences $1..$9 in RewriteConds test-against
7792 strings in addition to RewriteRules subst string. Second the grouped
7793 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7794 via backreferences %1..%9 both in following RewriteCond test-against
7795 strings and RewriteRules subst string. This provides maximum flexibility
7796 through the use of backreferences.
7797 Additionally the rewriting engine was cleaned up by putting common
7798 code to the new expand_backrefs_inbuffer() function.
7799 [Ralf S. Engelschall]
7801 *) When merging the main server's <Directory> and <Location> sections into
7802 a vhost, put the main server's first and the vhost's second. Otherwise
7803 the vhost can't override the main server. [Dean Gaudet] PR#717
7805 *) The <Directory> code would merge and re-merge the same section after
7806 a match was found, possibly causing problems with some modules.
7809 *) ip-based vhosts are stored and queried using a hashing function, which
7810 has been shown to improve performance on servers with many ip-vhosts.
7811 Some other changes had to be made to accommodate this:
7812 - the * address for vhosts now behaves like _default_
7813 - the matching process now is:
7814 - match an ip-vhost directly via hash (possibly matches main
7816 - if that fails, just pretend it matched the main server
7817 - if so far only the main server has been matched, perform
7818 name-based lookups (ServerName, ServerAlias, ServerPath)
7819 *only on name-based vhosts*
7820 - if they fail, look for _default_ vhosts
7821 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7823 *) dbmmanage overhaul:
7824 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7825 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7826 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7827 - provide better seed for rand
7828 - prompt for password as per getpass(3) (turn off echo, read from
7830 - use "newstyle" crypt based on $Config{osname} ($^O)
7831 - will not add a user if already in database, use new `update' command
7833 - added `check' command to check a users' password
7834 - added `import' command to convert existing password text-files or
7835 dbm files exported with `view'
7836 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7839 *) Added psocket() which is a pool form of socket(), various places within
7840 the proxy weren't properly blocking alarms while registering the cleanup
7841 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7842 was a bug where the client socket was being close()d twice due a still
7843 registered cleanup. [Dean Gaudet]
7845 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7848 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7849 [Jason Venner <jason@idiom.com>] PR#667
7851 *) Enable ``=""'' for RewriteCond directives to match against
7852 the empty string. This is the preferred way instead of ``^$''.
7853 [Ralf S. Engelschall]
7855 *) Fixed an infinite loop in mod_imap for references above the server root
7856 [Dean Gaudet] PR#748
7858 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7859 SendBufferSize, so that the TCP window can be set appropriately
7860 for LFNs. [Phillip A. Prindeville]
7862 *) mod_browser has been replaced by the more general mod_setenvif
7863 (courtesy of Paul Sutton). BrowserMatch* directives are still
7864 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7865 UnSetEnvIfZero directives. [Ken Coar]
7867 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7868 order for remote_host to be set (for logging, or for the env var
7869 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7872 *) mod_access overhaul:
7873 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7874 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7875 - Critical path was sped up by pre-computing a few things at config time.
7876 - The undocumented syntax "allow user-agents" was removed,
7877 the replacement is "allow from env=foobar" combined with mod_browser.
7878 - When used with hostnames it now forces a double-reverse lookup
7879 no matter what the directory settings are. This double-reverse
7880 doesn't affect any of the other routines that use the remote
7881 hostname. In particular it's still passed to CGIs and the log
7882 without the double-reverse check. Related PR#860.
7885 *) When a large bwrite() occurs (larger than the internal buffer size),
7886 while there is already something in the buffer, apache will combine
7887 the large write and the buffer into a single writev(). (This is
7888 in anticipation of using mmap() for reading files.)
7891 *) In obscure cases where a partial socket write occurred while chunking,
7892 Apache would omit the chunk header/footer on the next block. Cleaned
7893 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7894 a bug where a long pause in DNS lookups could cause the last packet
7895 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7897 *) API: Added child_exit function to module structure. This is called
7898 once per "heavy-weight process" just before a server child exit()'s
7899 e.g. when max_requests_per_child is reached, etc.
7900 [Doug MacEachern, Dean Gaudet]
7902 *) mod_include cleanup showed that handle_else was being used to handle
7903 endif. It didn't cause problems, but it was cleaned up too.
7906 *) mod_cern_meta would attempt to find meta files for the directory itself
7907 in some cases, but not in others. It now avoids it in all cases.
7910 *) mod_mime_magic would core dump if there was a decompression error.
7911 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7913 *) PORT: some variants of DGUX require -lsocket -lnsl
7914 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7916 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7917 by the various fields (name, size, et cetera), either in ascending
7918 or descending order. Just click on the column header. [Ken Coar]
7920 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7921 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7922 the relatively safe direction. [Dean Gaudet] PR#344
7924 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7925 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7927 *) child_main avoids an unneeded call to select() when there is only one
7928 listening socket. [Dean Gaudet]
7930 *) In the event that the server is starved for idle servers it will
7931 spawn 1, then 2, then 4, ..., then 32 servers each second,
7932 doubling each second. It'll also give a warning in the errorlog
7933 since the most common reason for this is a poor StartServers
7934 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7935 the maximum. [Dean Gaudet]
7937 *) Apache now provides an effectively unbuffered connection for
7938 CGI scripts. This means that data will be sent to the client
7939 as soon as the CGI pauses or stops output; previously, Apache would
7940 buffer the output up to a fixed buffer size before sending, which
7941 could result in the user viewing an empty page until the CGI finished
7942 or output a complete buffer. It is no longer necessary to use an
7943 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7944 in a language that by default does buffering (e.g. perl) this
7945 shouldn't have a detrimental effect on performance.
7947 "nph-" CGIs, which formerly provided a direct socket to the client
7948 without any server post-processing, were not fully compatible with
7949 HTTP/1.1 or SSL support. As such they would have had to implement
7950 the transport details, such as encryption or chunking, in order
7951 to work properly in certain situations. Now, the only difference
7952 between nph and non-nph scripts is "non-parsed headers".
7953 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7955 *) If a BUFF is switched from buffered to unbuffered reading the first
7956 bread() will return whatever remained in the buffer prior to the
7957 switch. [Dean Gaudet]
7959 Changes with Apache 1.3a1
7961 *) Added another Configure helper script: TestLib. It determines
7962 if a specified library exists. [Jim Jagielski]
7964 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7965 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7968 *) PORT: Some architectures use size_t for various lengths in network
7969 functions such as accept(), and getsockname(). The definition
7970 NET_SIZE_T is used to control this. [Dean Gaudet]
7972 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7973 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7974 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7976 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7977 [Igor N Kovalenko <infoh@mail.wplus.net>]
7979 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7980 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7981 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

8002 *) AddModuleInfo directive for mod_info which allows you to annotate
8003 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
8005 *) Added NoProxy directive to avoid using ProxyRemote for selected

8010 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
8011 header to the remote host in the proxy. [Sameer Parekh and
8014 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
8015 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
8016 URLs, fixed rewritelog(), fixed forced response code handling on
8017 redirects from within .htaccess files, disabled pipe locking under
8018 braindead SunOS 4.1.x, allow env variables to be set even on rules with
8019 no substitution, bugfixed situations where HostnameLookups is off, made
8020 mod_rewrite more thread-safe for NT port and fixed problem when creating
8021 an empty query string via "xxx?".
8022 This update also removes the copyright of Ralf S. Engelschall,
8023 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
8024 exclusively copyrighted by the Apache Group now. This happened because
8025 the author now has gifted mod_rewrite exclusively to the Apache Group and
8026 no longer maintains an external version.
8027 [Ralf S. Engelschall]
8029 *) API: Added child_init function to module structure. This is called
8030 once per "heavy-weight process" before any requests are handled.
8031 See http_config.h for more details. [Dean Gaudet]
8033 *) Anonymous_LogEmail was logging on each subrequest.

8036 *) API: Added is_initial_req() which tests if the request being
8037 processed is the initial request, or a subrequest.
8040 *) Extended SSI (mod_include) now handles additional relops for
8041 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
8043 *) Configure fixed to correctly propagate user-selected options and
8044 settings (such as CC and OPTIM) to Makefiles other than
8045 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
8047 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
8048 directory indices to start with the contents of the HeaderName file
8049 if there is one. If there isn't one, the behaviour is unchanged.
8050 [Ken Coar, Roy Fielding, Andrey A. Chernov]
8052 *) WIN32: Modules can now be dynamically loaded DLLs using the
8053 LoadModule/LoadFile directives. Note that module DLLs must be
8054 compiled with the multithreaded DLL version of the runtime library.
8055 [Alexei Kosut and Ben Laurie]
8057 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
8058 This allows the admin to completely remove automatic indexing
8059 from the server, while still supporting the basic functions of
8060 trailing-slash redirects and DirectoryIndex files. Note that if
8061 you're carrying over an old Configuration file and you use directory
8062 indexing then you'll want to add:
8064 Module autoindex_module mod_autoindex.o
8066 before mod_dir in your Configuration. [Dean Gaudet]
8068 *) popendir/pclosedir created to properly protect directory scanning.
8069 [Dean Gaudet] PR#525
8071 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
8072 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
8073 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
8076 *) The AccessFileName directive can now take more than one filename.

8087 main httpd process's PID. [Jim Jagielski]
8089 *) Makefile.nt added - to build all the bits from the command line:
8090 nmake -f Makefile.nt
8091 Doesn't yet work properly. [Ben Laurie]
8093 *) Default text of 404 error is now "Not Found" rather than the
8094 potentially misleading "File Not Found". [Ken Coar]
8096 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
8097 for the net if we require people that actually need this data to
8098 enable it. [Linus Torvalds]
8100 *) directory_walk() is an expensive function, keep a little more state to
8101 avoid needless string counting. Add two new functions make_dirstr_parent
8102 and make_dirstr_prefix which replace all existing uses of make_dirstr.
8103 The new functions are a little less general than make_dirstr, but
8104 work more efficiently (less memory, less string counting).
8107 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
8108 to LDFLAGS) to avoid complications with lex rules in make files.
8109 [Dean Gaudet] PR#372
8111 *) run_method optimized to avoid needless scanning over NULLs in the
8112 module list. [Dean Gaudet]
8114 *) Revamp of (unix) scoreboard management code such that it avoids
8115 unnecessary traversals of the scoreboard on each hit. This is
8116 particularly important for high volume sites with a large
8117 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
8118 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
8119 httpd.h. [Dean Gaudet]
8121 *) In configurations using multiple Listen statements it was possible for
8122 busy sockets to starve other sockets of service. [Dean Gaudet]
8124 *) Added hook so standalone_main can be replaced at compile time
8125 (define STANDALONE_MAIN)
8128 *) Lowest-level read/write functions in buff.c will be replaced with
8129 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
8130 compile time. The default sfio discipline will behave as apache
8131 would without sfio compiled in.
8134 *) Enhance UserDir directive (mod_userdir) to accept a list of
8135 usernames for the 'disable' keyword, and add 'enable user...' to
8136 selectively *en*able userdirs if they're globally disabled.
8139 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
8140 will work with Netscape dbm files. (dbmmanage will probably not
8141 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
8143 *) Add a ListenBacklog directive to control the backlog parameter
8144 passed to listen(). Also change the default to 511 from 512.
8147 *) API: A new handler response DONE which informs apache that the
8148 request has been handled and it can finish off quickly, similar to
8149 how it handles errors. [Rob Hartill]
8151 *) Turn off chunked encoding after sending terminating chunk/footer
8152 so that we can't do it twice by accident. [Roy Fielding]
8154 *) mod_expire also issues Cache-Control: max-age headers.
8157 *) API: Added kill_only_once option for free_proc_chain so that it won't
8158 aggressively try to kill off specific children. For fastcgi.
8159 [Stanley Gambarin <gambarin@OpenMarket.com>]
8161 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
8163 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
8164 When used together, these cause mod_dir to emit HEIGHT and WIDTH
8165 attributes in the FancyIndexing IMG tags. [Ken Coar]
8167 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
8169 *) PORT: Added Windows NT support

8172 Changes with Apache 1.2.6
8174 *) mod_include when using XBitHack Full would send ETags in addition to
8175 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
8176 [Dean Gaudet] PR#1133
8178 *) SECURITY: When a client connects to a particular port/addr, and
8179 gives a Host: header ensure that the virtual host requested can
8180 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
8182 *) Support virtual hosts with wildcard port and/or multiple ports
8183 properly. [Ed Korthof <ed@organic.com>]
8185 *) Fixed some case-sensitivity issues according to RFC2068.
8188 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
8189 and mod_include.c. [Dean Gaudet]
8191 *) Variable 'cwd' was being used pointlessly before being set.
8194 *) SIGURG doesn't exist on all platforms.
8195 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
8197 *) When an error occurs during a POST, or other operation with a

8201 *) When an error occurs in fcntl() locking suggest the user look up
8202 the docs for LockFile. [Dean Gaudet]
8204 *) table_set() and table_unset() did not deal correctly with
8205 multiple occurrences of the same key. [Stephen Scheck
8206 <sscheck@infonex.net>, Ben Laurie] PR#1604
8208 *) send_fd_length() did not calculate total_bytes_sent properly in error
8209 cases. [Ben Reser <breser@regnow.com>] PR#1366
8211 *) r->connection->user was allocated in the wrong pool causing corruption
8212 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
8214 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
8215 Also removed the auto-generated link to www.apache.org that was the
8216 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
8218 *) Multiple "close" tokens may have been set in the "Connection"
8219 header, not an error, but a waste.
8220 [Ronald.Tschalaer@psi.ch] PR#1683
8222 *) "basic" and "digest" auth tokens should be tested case-insensitive.
8223 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
8225 *) It appears the "257th byte" bug (see
8226 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
8227 at the 256th byte as well. Fixed. [Dean Gaudet]
8229 *) mod_rewrite would not handle %3f properly in some situations.
8232 *) Apache could generate improperly chunked HTTP/1.1 responses when
8233 the bputc() or rputc() functions were used by modules (such as
8234 mod_include). [Dean Gaudet]
8236 *) #ifdef wrap a few #defines in httpd.h to make life easier on
8237 some ports. [Ralf Engelschall]
8239 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
8241 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
8243 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
8245 Changes with Apache 1.2.5
8247 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
8248 only an issue on systems without a MAXDNAME define or where
8249 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
8251 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
8254 *) Fix core dump in the ftp proxy when reading incorrectly formatted
8255 directory listings. [Marc Slemko]
8257 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
8260 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
8261 is used to read various types of files such as htaccess and
8262 htpasswd files. [Marc Slemko]
8264 *) SECURITY: Ensure that the buffer returned by ht_time is always
8265 properly null terminated. [Marc Slemko]
8267 *) SECURITY: General mod_include cleanup, including fixing several
8268 possible buffer overflows and a possible infinite loop. This cleanup
8269 was done against 1.3 code and then backported to 1.2, the result
8270 is a large difference (due to indentation cleanup in 1.3 code).
8271 Users interested in seeing a smaller set of relevant differences
8272 should consider comparing against src/modules/standard/mod_include.c
8273 from the 1.3b3 release. Non-indentation changes to mod_include
8274 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
8276 *) SECURITY: Numerous changes to mod_imap in a general cleanup
8277 including fixing a possible buffer overflow. This cleanup also
8278 was done with 1.3 code as a basis, see the the previous note
8279 about mod_include. [Dean Gaudet]
8281 *) SECURITY: If a htaccess file can not be read due to bad
8282 permissions, deny access to the directory with a HTTP_FORBIDDEN.
8283 The previous behavior was to ignore the htaccess file if it could not
8284 be read. This change may make some setups with unreadable
8285 htaccess files stop working. PR#817 [Marc Slemko]
8287 *) SECURITY: no2slash() was O(n^2) in the length of the input.
8288 Make it O(n). This inefficiency could be used to mount a denial
8289 of service attack against the Apache server. Thanks to

8315 Changes with Apache 1.2.4
8317 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
8318 always making requests with the full-URI instead of just the URI path.
8319 [Marc Slemko, Roy Fielding]
8321 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
8322 on this platform. [Marc Slemko]
8324 Changes with Apache 1.2.3
8326 *) The request to a remote proxy was mangled if it was generated as the
8327 result of a ProxyPass directive. URL schemes other than http:// were not
8328 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

8335 do for errors and cached responses. [Roy Fielding]
8337 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8339 Changes with Apache 1.2.2 [not released]
8341 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8342 happily skip past access checks on subdirectories looked up with relative
8343 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8346 *) Add lockfile name to error message printed out when
8347 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8350 *) Enhanced the chunking and error handling inside the buffer functions.

8354 a vhost, put the main server's first and the vhost's second. Otherwise
8355 the vhost can't override the main server. [Dean Gaudet] PR#717
8357 *) The <Directory> code would merge and re-merge the same section after
8358 a match was found, possibly causing problems with some modules.

8362 [Dean Gaudet] PR#748
8364 *) mod_include cleanup showed that handle_else was being used to handle
8365 endif. It didn't cause problems, but it was cleaned up too.
8368 *) Last official synchronization of mod_rewrite with author version (because
8369 mod_rewrite is now directly developed by the author at the Apache Group):
8370 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8371 minus WIN32/NT stuff, but plus copyright removement.

8415 *) API: In HTTP/1.1, whether or not a request message contains a body
8416 is independent of the request method and based solely on the presence

8474 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS

8476 this should make supporting large numbers of vhosts with many open

8530 Changes with Apache 1.2
8532 Changes with Apache 1.2b11
8534 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
8536 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
8537 [Doug MacEachern, Rob Hartill]
8539 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
8540 reading from one buffer and writing to another, at least until it has
8541 a custom timeout handler. [Roy Fielding and Petr Lampa]
8543 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
8544 apparently due to a mismatch between sigaction and setjmp.
8545 [Roy Fielding] PR#502
8547 *) Log correct status code if we timeout before receiving a request (408)
8548 or if we received a request-line that was too long to process (414).
8549 [Ed Korthof and Roy Fielding] PR#601
8551 *) Virtual hosts with the same ServerName, but on different ports, were
8552 not being selected properly. [Ed Korthof]
8554 *) Added code to return the requested IP address from proxy_host2addr()
8555 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
8556 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8557 [Chuck Murcko] PR#614
8559 *) If multiple requests on a single connection are used to retrieve
8560 data from different virtual hosts, the virtual host list would be
8561 scanned starting with the most recently used VH instead of the first,
8562 causing most virtual hosts to be ignored.
8563 [Paul Sutton and Martin Mares] PR#610
8565 *) The OS/2 handling of process group was broken by a porting patch for
8566 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
8568 *) Inherit virtual server port from main server if none (or "*") is
8569 given for VirtualHost. [Dean Gaudet] PR#576
8571 *) If the lookup for a DirectoryIndex name with content negotiation
8572 has found matching variants, but none are acceptable, return the
8573 negotiation result if there are no more DirectoryIndex names to lookup.
8574 [Petr Lampa and Roy Fielding]
8576 *) If a soft_timeout occurs after keepalive is set, then the main child
8577 loop would try to read another request even though the connection
8578 has been aborted. [Roy Fielding]
8580 *) Configure changes: Allow for whitespace at the start of a
8581 Module declaration. Also, be more understanding about the
8582 CC=/OPTIM= format in Configuration. Finally, fix compiler
8583 flags if using HP-UX's cc compiler. [Jim Jagielski]
8585 *) Subrequests and internal redirects now inherit the_request from the
8586 original request-line. [Roy Fielding]
8588 *) Test for error conditions before creating output header fields, since
8589 we don't want the error message to include those fields. Likewise,
8590 reset the content_language(s) and content_encoding of the response
8591 before generating or redirecting to an error message, since the new
8592 message will have its own Content-* definitions. [Dean Gaudet]
8594 *) Restored the semantics of headers_out (headers sent only with 200..299
8595 and 304 responses) and err_headers_out (headers sent with all responses).
8596 Avoid the overhead of copying tables if err_headers_out is empty
8597 (the usual case). [Roy Fielding]
8599 *) Fixed a couple places where a check for the default Content-Type was
8600 not properly checking both the value configured by the DefaultType
8601 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8602 of DEFAULT_TYPE to match the documented default (text/plain).
8603 [Dean Gaudet] PR#506
8605 *) Escape the HTML-sensitive characters in the Request-URI that is
8606 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8608 *) Properly initialize the flock structures used by the mutex locking
8609 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8612 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8613 (and NCSA httpd) definition wherein it was the extra path info beyond
8614 the CGI script filename. The environment variable FILEPATH_INFO has
8615 been removed, and instead we supply the original REQUEST_URI to any
8616 script that wants to be Apache-specific and needs the real URI path.
8617 This solves a problem with existing scripts that use extra path info
8618 in the ScriptAlias directive to pass options to the CGI script.
8621 *) The _default_ change in 1.2b10 will change the behaviour on configs
8622 that use multiple Listen statements for listening on multiple ports.
8623 But that change is necessary to make _default_ consistent with other
8624 forms of <VirtualHost>. It requires such configs to be modified
8625 to use <VirtualHost _default_:*>. The documentation has been
8626 updated. [Dean Gaudet] PR#530
8628 *) If an ErrorDocument CGI script is used to respond to an error
8629 generated by another CGI script which has already read the message
8630 body of the request, the server would block trying to read the
8631 message body again. [Rob Hartill]
8633 *) signal() replacement conflicted with a define on QNX (and potentially
8634 other platforms). Fixed. [Ben Laurie] PR#512
8636 Changes with Apache 1.2b10
8638 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8639 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8641 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8643 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
8645 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
8646 config, in case the hostent struct returned is trash.
8647 [Chuck Murcko] PR #491
8649 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8650 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8652 Changes with Apache 1.2b9 [never announced]
8654 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8655 changes and in anticipation of 1.2 final release. [Roy Fielding]
8657 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8658 the connection (e.g., when user presses Stop). Apache will now stop
8659 trying to send a message body immediately after an error from write.
8660 [Roy Fielding and Nathan Kurz] PR#335
8662 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8663 than mod_alias, and mod_alias has higher priority than mod_proxy;
8664 rearranged other modules to enhance understanding of their purpose
8665 and relative order (and maybe even reduce some overhead).
8666 [Roy Fielding and Sameer Parekh]
8668 *) Fix graceful restart. Eliminate many signal-related race
8669 conditions in both forms of restart, and in SIGTERM. See
8670 htdocs/manual/stopping.html for details on stopping and
8671 restarting the parent. [Dean Gaudet]
8673 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8674 memory allocator to avoid a behaviour that required extra blocks to
8675 be allocated. [Dean Gaudet]
8677 *) Allow suexec to access files relative to current directory but not
8678 above. (Excluding leading / or any .. directory.) [Ken Coar]
8681 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8682 PR#367, 368, 354, 453
8684 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8685 while obtaining the /~user and save the username in a separate data
8686 area so that it won't be overwritten by the call to getgrgid(), and
8687 fix some misuse of the pool string allocation functions. Also fixes
8688 a general problem with parsing URL query info into args for CGI scripts.
8689 [Roy Fielding] PR#339, 367, 354, 453
8691 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
8693 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
8695 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
8696 AuthDBAuthoritative. [Marc Slemko] PR#420
8698 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8700 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8701 object that can't be PUT, or FOOBAR for some method FOOBAR that
8702 apache doesn't know about at all). Log 404s that occur in mod_include.
8703 [Paul Sutton, John Van Essen]
8705 *) If a soft timeout (or lingerout) occurs while trying to flush a
8706 buffer or write inside buff.c or fread'ing from a CGI's output,
8707 then the timeout would be ignored. [Roy Fielding] PR#373
8709 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8710 parsing of headers. If the terminating empty-line CRLF occurs starting
8711 at the 256th or 257th byte of output, then Navigator will think a normal
8712 image is invalid. We are guessing that this is because their initial
8713 read of a new request uses a 256 byte buffer. We check the bytes written
8714 so far and, if we are about to tickle the bug, we instead insert a
8715 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8717 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8718 of an external redirection. [Roy Fielding and Paul Sutton]
8720 *) Configure would create a broken Makefile if the configuration file
8721 contained a commented-out Rule. [Roy Fielding]
8723 *) Promote per_dir_config and subprocess_env from the subrequest to the
8724 main request in mod_negotiation. In particular this fixes a bug
8725 where <Files> sections wouldn't properly apply to negotiated content.
8728 *) Fix a potential deadlock in mod_cgi script_err handling.
8729 [Ralf S. Engelschall]
8731 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8734 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8735 .htaccess files because the RewriteBase was not replaced correctly.
8736 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8737 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8739 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8740 1.x the settings are those of pre-1.2b8. For 2.x we include
8741 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8742 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8743 [Dean Gaudet] PR#336, PR#340
8745 *) Redirect did not preserve ?query_strings when present in the client's
8746 request. [Dean Gaudet]
8748 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8750 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8752 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8754 *) Add mod_example (illustration of API techniques). [Ken Coar]
8756 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8758 *) Improve handling of directories when filenames have spaces in them.
8761 *) For hosts with multiple IP addresses, try all additional addresses if
8762 necessary to get a connect. Fail only if hostent address list is
8763 exhausted. [Chuck Murcko]
8765 *) More signed/unsigned port fixes. [Dean Gaudet]
8767 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8770 Changes with Apache 1.2b8
8772 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8773 to it. [Marc Slemko]
8775 *) The addition of <Location> and <File> directives made the
8776 sub_req_lookup_simple() function bogus, so we now handle
8777 the special cases directly. [Dean Gaudet]
8779 *) We now try to log where the server is dumping core when a fatal
8780 signal is received. [Ken Coar]
8782 *) Improved lingering_close by adding a special timeout, removing the
8783 spurious log messages, removing the nonblocking settings (they
8784 are not needed with the better timeout), and adding commentary
8785 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8786 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8788 *) Send error messages about setsockopt failures to the server error
8789 log instead of stderr. [Roy Fielding]
8791 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8793 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8794 processing a subrequest, allocate memory from r->main->pool instead
8795 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8796 in the middle of an SSI request. [Dean Gaudet] PR #122
8798 *) Fixed status of response when POST is received for a nonexistent URL
8799 (was sending 405, now 404) and when any method is sent with a
8800 full-URI that doesn't match the server and the server is not acting
8801 as a proxy (was sending 501, now 403). [Roy Fielding]
8803 *) Host port changed to unsigned short. [Ken Coar] PR #276
8805 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8807 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8809 *) Report extra info from errno with many errors that cause httpd to exit.
8810 spawn_child, popenf, and pclosef now have valid errno returns in the
8811 event of an error. Correct problems where errno was stomped on
8812 before being reported. [Dean Gaudet]
8814 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8815 never called, and thus the filesystem would remain full indefinitely.
8816 We now also remove incomplete cache files left if the origin server
8817 didn't send a Content-Length header and either the client has aborted
8818 transfer or bwrite() to client has failed. [Petr Lampa]
8820 *) Fixed the handling of module and script-added header fields.
8821 Improved the interface for sending header fields and reduced
8822 the duplication of code between sending okay responses and errors.
8823 We now always send both headers_out and err_headers_out, and
8824 ensure that the server-reserved fields are not being overridden,
8825 while not overriding those that are not reserved. [Roy Fielding]
8827 *) Moved transparent content negotiation fields to err_headers_out
8828 to reflect above changes. [Petr Lampa]
8830 *) Fixed the determination of whether or not we should make the
8831 connection persistent for all of the cases where some other part
8832 of the server has already indicated that we should not. Also
8833 improved the ordering of the test so that chunked encoding will
8834 be set whenever it is desired instead of only when KeepAlive
8835 is enabled. Added persistent connection capability for most error
8836 responses (those that do not indicate a bad input stream) when
8837 accessed by an HTTP/1.1 client. [Roy Fielding]
8839 *) Added missing timeouts for sending header fields, error responses,
8840 and the last chunk of chunked encoding, each of which could have
8841 resulted in a process being stuck in write forever. Using soft_timeout
8842 requires that the sender check for an aborted connection rather than
8843 continuing after an EINTR. Timeouts that used to be initiated before
8844 send_http_header (and never killed) are now initiated only within or
8845 around the routines that actually do the sending, and not allowed to
8846 propagate above the caller. [Roy Fielding]
8848 *) mod_auth_anon required an @ or a . in the email address, not both.
8851 *) per_dir_defaults weren't set correctly until directory_walk for
8852 name-based vhosts. This fixes an obscure bug with the wrong config
8853 info being used for vhosts that share the same ip as the server.
8856 *) Improved generation of modules/Makefile to be more generic for
8857 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8859 *) Generate makefile dependency for Configuration based on the actual
8860 name given when running the Configure process. [Dean Gaudet]
8862 *) Fixed problem with vhost error log not being set prior to
8863 initializing virtual hosts. [Dean Gaudet]
8865 *) Fixed infinite loop when a trailing slash is included after a type map
8866 file URL (extra path info). [Petr Lampa]
8868 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8870 *) Add documentation for DNS issues (reliability and security), and try
8871 to explain the virtual host matching process. [Dean Gaudet]
8873 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8874 fails while parsing the configuration file. [Dean Gaudet]
8876 *) Improved calls to setsockopt. [Roy Fielding]
8878 *) Negotiation changes: Don't output empty content-type in variant list;
8879 Output charset in variant list; Return sooner from handle_multi() if
8880 no variants found; Add handling of '*' wildcard in Accept-Charset.
8881 [Petr Lampa and Paul Sutton]
8883 *) Fixed overlaying of request/sub-request notes and headers in
8884 mod_negotiation. [Dean Gaudet]
8886 *) If two variants' charset quality are equal and one is the default
8887 charset (iso-8859-1), then prefer the variant that was specifically
8888 listed in Accept-Charset instead of the default. [Petr Lampa]
8890 *) Memory allocation problem in push_array() -- it would corrupt memory
8891 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8893 *) invoke_handler() doesn't handle mime arguments in content-type
8896 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8899 *) Fixed problem with ErrorDocument not working for virtual hosts
8900 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8902 *) Log an error message if we get a request header that is too long,
8903 since it may indicate a buffer overflow attack. [Marc Slemko]
8905 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8906 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8907 [Ken Coar] PR #146, #187
8909 *) Added table entry placeholder for new header_parser callback
8910 in all of the distributed modules. [Ken Coar] PR #191
8912 *) Allow for cgi files without the .EXE extension on them under OS/2.
8913 [Garey Smiley] PR #59
8915 *) Fixed error message when resource is not found and URL contains
8916 path info. [Petr Lampa and Dean Gaudet] PR #40
8918 *) Fixed user and server confusion over what should be a virtual host
8919 and what is the main server, resulting in access to something
8920 other than the name defined in the virtualhost directive (but
8921 with the same IP address) failing. [Dean Gaudet]
8923 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8924 AIX; improves the redirection stuff to enable the users to generally
8925 redirect to http, https, gopher and ftp; added TIME variable for
8926 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8927 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8928 can be used in conjunction with %{TIME} or other variables to create
8929 time-dependent rewriting rules. [Ralf S. Engelschall]
8931 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8932 Module authors may need to adjust their code for proper cleanup to take
8933 place (that is, call note_cleanups_for_fd()). This change fixes problems
8934 with file descriptors being erroneously closed when the proxy module was
8935 in use. [Ben Laurie]
8937 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8938 initgroups() to hose the group information needed for later
8939 comparisons. [Randy Terbush]
8941 *) Remove unnecessary call to va_end() in create_argv() which
8942 caused a SEGV on some systems.
8944 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8947 *) Clear memory allocated for listeners. [Randy Terbush]
8949 *) Improved handling of IP address as a virtualhost address and
8950 introduced "_default_" as a synonym for the default vhost config.

8960 - replace protocol response numbers with symbols
8961 - save variant-list into main request notes
8962 - free allocated memory from subrequests

8965 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8966 "HTTP/#.# ###*" to be more lenient about what we accept.
8969 *) more proxy FTP bug fixes:
8970 - Changed send_dir() to remove user/passwd from displayed URL.
8971 - Changed login error messages to be more descriptive.
8972 - remove setting of SO_DEBUG socket option
8973 - Make ftp_getrc() more lenient about multiline responses,
8974 specifically, 230 responses which don't have continuation 230-
8975 on each line). These seem to be all NT FTP servers, and while
8976 perhaps questionable, they appear to be legal by RFC 959.
8977 - Add missing kill_timeout() after transfer to user completes.
8980 *) Fixed problem where a busy server could hang when restarting
8981 after being sent a SIGHUP due to child processes not exiting.
8984 *) Modify mod_include escaping so a '\' only signifies an escaped
8985 character if the next character is one that needs
8986 escaping. [Ben Laurie]
8988 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8989 used with a 'base' directive that does not have a '/' in it.
8990 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8992 *) Reduced the default timeout from 1200 seconds to 300, and the
8993 one in the sample configfile from 400 to 300. [Marc Slemko]
8995 *) Stop vbprintf from crashing if given a NULL string pointer;
8996 print (null) instead. [Ken Coar]
8998 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.

9001 *) Fixed problem with mod_cgi-generated internal redirects trying to
9002 read the request message-body twice. [Archie Cobbs and Roy Fielding]
9004 *) Reduced timeout on lingering close, removed possibility of a blocked
9005 read causing the child to hang, and stopped logging of errors if
9006 the socket is not connected (reset by client). [Roy Fielding]
9008 *) Rearranged main child loop to remove duplication of code in
9009 select/accept and keep-alive requests, fixed several bugs regarding
9010 checking scoreboard_image for exit indication and failure to
9011 account for all success conditions and trap all error conditions,
9012 prevented multiple flushes before closing the socket; close the entire
9013 socket buffer instead of just one descriptor, prevent logging of
9014 EPROTO and ECONNABORTED on platforms where supported, and generally
9015 improved readability. [Roy Fielding]
9017 *) Extensive performance improvements. Cleaned up inefficient use of
9018 auto initializers, multiple is_matchexp calls on a static string,
9019 and excessive merging of response_code_strings. [Dean Gaudet]
9021 *) Added double-buffering to mod_include to improve performance on
9022 server-side includes. [Marc Slemko]

9027 - Fix array overrun problem in clean_env().
9028 - Fix allocation of PATH environment variable
9030 *) Removed extraneous blank line is description of mod_status chars.
9033 *) Logging of errors from the call_exec routine simply went nowhere,
9034 since the logfile fd has been closed, so now we send them to stderr.

9037 *) Fixed core dump when DocumentRoot is a CGI.

9045 as the DEC Alpha which is 64-bit but uses 32-bit ints.
9046 [Dean Gaudet and Ken Coar]
9048 *) Return a 302 response code to the client when sending a redirect
9049 due to a missing trailing '/' on a directory instead of a 301; now
9050 it is cacheable. [Markus Gyger]
9052 *) Fix condition where, if a bad directive occurs in .htaccess, and
9053 sub_request() goes first to this directory, then log_reason() will
9054 SIGSEGV because it doesn't have initialized r->per_dir_config.
9055 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
9057 *) Fix handling of lang_index in is_variant_better(). This was
9058 causing problems which resulted in the server sending the
9059 wrong language document in some cases. [Petr Lampa]
9061 *) Remove free() from clean_env() in suexec wrapper. This was nuking
9062 the clean environment on some systems.
9064 *) Tweak byteserving code (e.g. serving PDF files) to work around
9065 bugs in Netscape Navigator and Microsoft Internet Explorer.
9066 Emit Content-Length header when sending multipart/byteranges.
9069 *) Port to HI-UX/WE2. [Nick Maclaren]
9071 *) Port to HP MPE operating system for HP 3000 machines
9072 [Mark Bixby <markb@cccd.edu>]
9074 *) Fixed bug which caused a segmentation fault if only one argument
9075 given to RLimit* directives. [Ed Korthof]
9077 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
9079 *) Improved buffered output to the client by delaying the flush decision
9080 until the BUFF code is actually about to read the next request.
9081 This fixes a problem introduced in 1.2b5 with clients that send
9082 an extra CRLF after a POST request. Also improved chunked output
9083 performance by combining writes using writev() and removing as
9084 many bflush() calls as possible. NOTE: Platforms without writev()
9085 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
9086 or Configure, unless we have already done so. [Dean Gaudet]
9088 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
9090 *) Fixed mod_info output corruption bug introduced by buffer overflow
9091 fixes. [Dean Gaudet]
9093 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
9094 for the special case of a 304 response. [Paul Sutton]
9096 *) Improved handling of TRACE method by bypassing normal method handling
9097 and header parsing routines; fixed Allow response to always allow TRACE.
9100 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
9102 *) Cleaned-up some of the generated HTML. [Ken Coar]
9104 Changes with Apache 1.2b6
9106 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
9108 *) Fix typo introduced in fix for potential infinite loop around
9109 accept() in child_main(). This change caused the rev to 1.2b6.
9110 1.2b5 was never a public beta.
9112 Changes with Apache 1.2b5
9114 *) Change KeepAlive semantics (On|Off instead of a number), add
9115 MaxKeepAliveRequests directive. [Alexei Kosut]
9117 *) Various NeXT compilation patches, as well as a change in
9118 regex/regcomp.c since that file also used a NEXT define.
9121 *) Allow * to terminate the end of a directory match in mod_dir.
9122 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
9124 *) Don't call can_exec() if suexec_enabled. Calling this requires
9125 scripts executed by the suexec wrapper to be world executable, which
9126 defeats one of the advantages of running the wrapper. [Randy Terbush]
9128 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
9131 *) Migration from sprintf() to snprintf() to avoid buffer
9132 overflows. [Marc Slemko]
9134 *) Provide portable snprintf() implementation (ap_snprintf)
9135 as well as *cvt family. [Jim Jagielski]
9137 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
9140 *) Remove mod_fastcgi.c from the distribution. This module appears
9141 to be maintained more through the Open Market channels and should
9142 continue to be easily available at http://www.fastcgi.com/
9144 *) Fixed bug in modules/Makefile that wouldn't allow building in more
9145 than one subdirectory (or cleaning, either). [Jeremy Laidman]
9147 *) mod_info assumed that the config files were relative to ServerRoot.
9150 *) CGI scripts called as an error document resulting from failed
9151 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
9153 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
9156 *) Properly check errno to prevent display of a directory index
9157 when server receives a long enough URL to confuse stat().
9160 *) Several security enhancements to suexec wrapper. It is _highly_
9161 recommended that previously installed versions of the wrapper
9162 be replaced with this version. [Randy Terbush, Jason Dour]
9164 - ~user execution now properly restricted to ~user's home
9165 directory and below.
9166 - execution restricted to UID/GID > 100
9167 - restrict passed environment to known variables
9168 - call setgid() before initgroups() (portability fix)
9169 - remove use of setenv() (portability fix)
9171 *) Add HTTP/1.0 response forcing. [Ben Laurie]
9173 *) Add access control via environment variables. [Ben Laurie]
9175 *) Add rflush() function. [Alexei Kosut]
9177 *) remove duplicate pcalloc() call in new_connection().
9179 *) Fix incorrect comparison which could allow number of children =
9180 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
9181 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
9183 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
9184 AIX PS/2, CONVEXOS. [Jim Jagielski]
9186 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
9187 It's more portable. [Martin Kraemer]
9189 *) Replace references to make in Makefile.tmpl with $(MAKE).
9192 *) Add ProxyBlock directive w/IP address caching. Add IP address
9193 caching to NoCache directive as well. ProxyBlock works with all
9194 handlers; NoCache now also works with FTP for anonymous logins.
9195 Still more code cleanup. [Chuck Murcko]
9197 *) Add "header parse" API hook [Ben Laurie]
9199 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
9201 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
9203 *) Correctly allow access and auth directives in <Files> sections in
9204 server config files. [Alexei Kosut]
9206 *) Fix bug with ServerPath that could cause certain files to be not
9207 found by the server. [Alexei Kosut]
9209 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
9210 double-quote from text and so that it properly checks for unsupported
9211 status codes using the new index_of_response interface. [Roy Fielding]
9213 *) Multiple fixes to the lingering_close code in order to avoid being
9214 interrupted by a stray timeout, to avoid lingering on a connection
9215 that has already been aborted or never really existed, to ensure that
9216 we stop lingering as soon as any error condition is received, and to
9217 prevent being stuck indefinitely if the read blocks. Also improves
9218 reporting of error conditions. [Marc Slemko and Roy Fielding]
9220 *) Fixed initialization of parameter structure for sigaction.
9221 [mgyger@itr.ch, Adrian Filipi-Martin]
9223 *) Fixed reinitializing the parameters before each call to accept and
9224 select, and removed potential for infinite loop in accept.
9225 [Roy Fielding, after useful PR from adrian@virginia.edu]
9227 *) Fixed condition where, if a child fails to fork, the scoreboard would
9228 continue to say SERVER_STARTING forever. Eventually, the main process
9229 would refuse to start new children because count_idle_servers() will
9230 count those SERVER_STARTING entries and will always report that there
9231 are enough idle servers. [Phillip Vandry]
9233 *) Fixed bug in bcwrite regarding failure to account for partial writes.
9234 Avoided calling bflush() when the client is pipelining requests.
9235 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
9237 *) Added description of "." mode in server-status [Jim Jagielski]
9239 Changes with Apache 1.2b4
9241 *) Fix possible race condition in accept_mutex_init() that
9242 could leave a small security hole open allowing files to be
9243 overwritten in cases where the server UID has write permissions.
9246 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
9248 *) Fix portablity problem in util_script where ARG_MAX may not be
9249 defined for some systems.
9251 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
9254 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
9255 style magic #! token for better script portability. [Garey Smiley]
9257 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
9258 execution for ~userdir CGI. [Jason Dour]
9260 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
9262 *) Fix month off by one in suexec wrapper logging.
9264 Changes with Apache 1.2b3:
9266 *) Fix error in mod_cgi which could cause resources not to be properly
9267 freed, or worse. [Dean Gaudet]
9269 *) Fix find_string() NULL pointer dereference. [Howard Fear]
9271 *) Add set_flag_slot() at the request of Dirk and others.
9274 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
9276 *) Add changes to improve the error message given for invalid
9277 ServerName parameters. [Dirk vanGulik]
9279 *) Add "Authoritative" directive for Auth modules that don't
9280 currently have it. This gives admin control to assign authoritative
9281 control to an authentication scheme and allow "fall through" for
9282 those authentication modules that aren't "Authoritative" thereby
9283 allowing multiple authentication mechanisms to be chained.
9286 *) Remove requirement for ResourceConfig/AccessConfig if not using
9287 the three config file layout. [Randy Terbush]
9289 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
9291 *) Changes to suexec wrapper to fix the following problems:
9292 1. symlinked homedirs will kill ~userdirs.
9293 2. initgroups() on Linux 2.0.x clobbers gr->grid.
9294 3. CGI command lines paramters problems
9295 4. pw-pwdir for "docroot check" still the httpd user's pw record.
9296 [Randy Terbush, Jason Dour]
9298 *) Change create_argv() to accept variable arguments. This fixes
9299 a problem where arguments were not getting passed to the CGI via
9300 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
9302 *) Collapse multiple slashes in path URLs to properly apply
9303 handlers defined by <Location>. [Alexei Kosut]
9305 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
9307 *) Improve the accuracy of request duration timings by setting
9308 r->request_time in read_request_line() instead of read_request().
9311 *) Reset timeout while reading via get_client_block() in mod_cgi.c
9312 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
9314 *) Add the ability to pass different Makefile.tmpl files to Configure
9315 using the -make flag. [Rob Hartill]
9317 *) Fix coredump triggered when sending a SIGHUP to the server caused
9318 by an assertion failure, in turn caused by an uninitialised field in a
9322 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
9323 PATH_INFO from previous versions of Apache (in certain situations,
9324 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9325 [later removed in 1.2b11]
9327 *) Add rwrite() function to API to allow for sending strings of
9328 arbitrary length. [Doug MacEachern]
9330 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9332 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9333 NeXT. [Jim Jagielski]
9335 *) Removed recent modification to promote the status code on internal
9336 redirects, since the correct fix was to change the default log format
9337 in mod_log_config so that it outputs the original status. [Rob Hartill]
9339 Changes with Apache 1.2b2:
9341 *) Update set_signals() to use sigaction() for setting handlers.
9342 This appears to fix a re-entrant problem in the seg_fault()
9343 bus_error() handlers. [Randy Terbush]
9345 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9347 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9349 *) proxy_http.c bugfixes: [Chuck Murcko]
9350 1) fixes possible NULL pointer reference w/NoCache
9351 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9352 host would cache nothing if it was in the local domain,
9353 and the local domain was in the NoCache list)
9354 3) Adds Host: header when not available
9355 4) Some code cleanup and clarification
9357 *) mod_include.c bugfixes:
9358 1) Fixed an ommission that caused include variables to not
9359 be parsed in config errmsg directives [Howard Fear]
9360 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9361 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9362 4) Allow backslash-escaping to all quoted text
9363 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9364 5) Pass variable to command line if not set in XSSI's env
9367 *) Fix infinite loop when processing Content-language lines in
9368 type-map files. [Alexei Kosut]
9370 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9372 *) Fixed problem in set_[user|group] that prevented CGI execution
9373 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9375 *) Added PORTING information file. [Jim Jagielski]
9377 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9379 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9381 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9382 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9384 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9385 which caused problems of systems where socket s_addr is >32bits.
9387 *) Added comment to explain (r->chunked = 1) side-effect in
9388 http_protocol.c [Roy Fielding]
9390 *) Replaced use of index() in mod_expires.c with more appropriate
9391 and portable isdigit() test. [Ben Laurie]
9393 *) Updated Configure for ...
9394 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9395 *-dg-dgux* (bad pattern match)
9396 QNX (DEF_WANTHSREGEX=yes)
9397 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9400 and added some user diagnostic info. [Ben Laurie]
9402 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9403 for better portability. [Jim Jagielski]
9405 *) Updated helpers/GuessOS for ...
9406 SCO 5 (recognize minor releases)
9407 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9408 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9409 IRIX64 (-sgi-irix64)
9410 ULTRIX (-unknown-ultrix)
9411 SINIX (-whatever-sysv4)
9412 NCR Unix (-ncr-sysv4)
9413 and fixed something in helpers/PrintPath [Ben Laurie]
9415 Changes with Apache 1.2b1
9417 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9419 Changes with Apache 1.1.1
9421 *) Fixed bug where Cookie module would make two entries in the
9422 logfile for each access [Mark Cox]
9424 *) Fixed bug where Redirect in .htaccess files would cause memory
9425 leak. [Nathan Neulinger]
9427 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9429 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9431 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9433 Changes with Apache 1.1.0
9435 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9437 *) Bring QNX support up to date. [Ben Laurie]
9439 *) Make virtual hosts default to main server keepalive parameters.
9440 [Alexei Kosut, Ben Laurie]
9442 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9444 *) Fix missing address family for connect, also remove unreachable statement
9445 in mod_proxy. [Ben Laurie]
9447 *) mod_env now turned on by default in Configuration.tmpl.
9449 *) Bugs which were fixed:
9450 a) yet more mod_proxy bugs [Ben Laurie]
9451 b) CGI works again with inetd [Alexei Kosut]
9452 c) Leading colons were stripped from passwords [osm@interguide.com]
9453 d) Another fix to multi-method Limit problem [jk@tools.de]
9455 Changes with Apache 1.1b4
9457 *) r->bytes_sent variable restored. [Robert Thau]
9459 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9461 *) More possibly unsecure programs removed from the support directory.
9463 *) More mod_auth_msql authentication improvements.
9465 *) VirtualHosts based on Host: headers no longer conflict with the
9468 *) OS/2 compatibility enhancements. [Gary Smiley]
9470 *) POST now allowed to directory index CGI scripts.
9472 *) Actions now work with files of the default type.
9474 *) Bugs which were fixed:
9475 a) more mod_proxy bugs
9476 b) early termination of inetd requests
9477 c) compile warnings on several systems
9478 d) problems when scripts stop reading output early
9480 Changes with Apache 1.1b3
9482 *) Much of cgi-bin and all of cgi-src has been removed, due to
9483 various security holes found and that we could no longer support
9486 *) The "Set-Cookie" header is now special-cased to not merge multiple
9487 instances, since certain popular browsers can not handle multiple
9488 Set-Cookie instructions in a single header. [Paul Sutton]
9490 *) rprintf() added to buffer code, occurrences of sprintf removed.
9493 *) CONNECT method for proxy module, which means tunneling SSL should work.
9494 (No crypto needed) Also a NoCache config directive.
9496 *) Several API additions: pstrndup(), table_unset() and get_token()
9497 functions now available to modules.
9499 *) mod_imap fixups, in particular Location: headers are now complete
9502 *) New "info" module which reports on installed module set through a
9503 special URL, a la mod_status.
9505 *) "ServerPath" directive added - allows for graceful transition
9506 for Host:-header-based virtual hosts.
9508 *) Anonymous authentication module improvements.
9510 *) MSQL authentication module improvements.
9512 *) Status module design improved - output now table-based. [Ben Laurie]
9514 *) htdigest utility included for use with digest authentication
9517 *) mod_negotiation: Accept values with wildcards to be treated with
9518 less priority than those without wildcards at the same quality
9519 value. [Alexei Kosut]
9521 *) Bugs which were fixed:
9522 a) numerous mod_proxy bugs
9523 b) CGI early-termination bug [Ben Laurie]
9524 c) Keepalives not working with virtual hosts
9525 d) RefererIgnore problems
9526 e) closing fd's twice in mod_include (causing core dumps on
9527 Linux and elsewhere).
9529 Changes with Apache 1.1b2
9532 a) core dumps in mod_digest
9533 b) truncated hostnames/ip address in the logs
9534 c) relative URL's in mod_imap map files
9536 Changes with Apache 1.1b1
9538 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9540 Changes with Apache 1.0.3
9542 *) Internal redirects which occur in mod_dir.c now preserve the
9543 query portion of a request (the bit after the question mark).
9546 *) Escape active characters '<', '>' and '&' in html output in
9547 directory listings, error messages and redirection links.
9550 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9552 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9555 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9557 *) Reset timeout timer after each successful fwrite() to the network.
9558 This patch adds a reset_timeout() procedure that is called by
9559 send_fd() to reset the timeout ever time data is written to the net.
9562 *) timeout() signal handler now checks for SIGPIPE and reports
9563 lost connections in a more user friendly way. [Rob Hartill]
9565 *) Location of the "scoreboard" file which used to live in /tmp is
9566 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9567 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9569 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9571 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9572 which caused a SEGV with cookies enabled
9574 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9577 *) Log the UNIX textual error returned by some system calls, in
9578 particular errors from accept() [David Robinson]
9580 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9582 Changes with Apache 1.0.2
9584 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9585 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9587 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9590 *) past changes to http_config.c to only use the
9591 setrlimit function on systems defining RLIMIT_NOFILE
9592 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9593 for SUNOS and prototypes the needed functions.
9595 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9598 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9600 *) Merge multiple headers from CGI scripts instead of taking last
9601 one. [David Robinson]
9603 *) Add support for SCO 5. [Ben Laurie]
9605 Changes with Apache 1.0.1
9607 *) Silence mod_log_referer and mod_log_agent if not configured
9610 *) Recursive includes can occur if the client supplies PATH_INFO data
9611 and the server provider uses relative links; as file.html
9612 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9614 *) The replacement for initgroups() did not call {set,end}grent(). This
9615 had two implications: if anything else used getgrent(), then
9616 initgroups() would fail, and it was consuming a file descriptor.
9619 *) On heavily loaded servers it was possible for the scoreboard to get
9620 out of sync with reality, as a result of a race condition.
9621 The observed symptoms are far more Apaches running than should
9622 be, and heavy system loads, generally followed by catastrophic
9623 system failure. [Ben Laurie]
9625 *) Fix typo in license. [David Robinson]
9627 Changes with Apache 1.0.0 23 Nov 1995
9629 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9631 Changes with Apache 0.8.16 05 Nov 1995
9633 *) New man page for 'httpd' added to support directory [David Robinson]
9635 *) .htgroup files can have more than one line giving members for a
9636 given group (each must have the group name in front), for NCSA
9637 back-compatibility [Robert Thau]
9639 *) Mutual exclusion around accept() is on by default for SVR4 systems
9640 generally, since they generally can't handle multiple processes in
9641 accept() on the same socket. This should cure flaky behavior on
9642 a lot of those systems. [David Robinson]
9644 *) AddType, AddEncoding, and AddLanguage directives take multiple
9645 extensions on a single command line [David Robinson]
9647 *) UserDir can be disabled for a given virtual host by saying
9648 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9649 that this didn't work. [David Robinson]
9651 *) Compiles on QNX [Ben Laurie]
9653 *) Corrected parsing of ctime time format [David Robinson]
9655 *) httpd does a perror() before exiting if it can't log its pid
9656 to the PidFile, to make diagnosing the error a bit easier.
9659 *) <!--#include file="..."--> can no longer include files in the
9660 parent directory, for NCSA back-compatibility. [David Robinson]
9662 *) '~' is *not* escaped in URIs generated for directory listings
9665 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9667 *) Fixed bug involving handling URIs with escaped %-characters
9668 in redirects [David Robinson]
9670 Changes with Apache 0.8.15 14 Oct 1995
9672 *) Switched to new, simpler license
9674 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9676 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9678 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9680 *) Correctly handles internal redirects to files with names containing '%'
9683 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9685 *) Use geteuid() rather than getuid() to see if we have root privilege,
9686 so that server correctly resets privilege if run setuid root. [Andrew
9689 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9692 *) Fix relative URLs in imagemap files [Randy Terbush]
9694 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9697 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9698 entries all name the same one. [David Robinson]
9700 *) Fix directory listings with filenames containing unusual characters
9703 *) Better URI-escaping for generated URIs in directories with filenames
9704 containing unusual characters [Ben Laurie]
9706 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9708 *) Unblock alarms on error return from spawn_child() [David Robinson]
9710 *) Sample Config files have extra note for SCO users [Ben Laurie]
9712 *) Configuration has note for HP-UX users [Rob Hartill]
9714 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9716 *) Nuked bogus #define in httpd.h [David Robinson]
9718 *) Better test for whether a system has setrlimit() [David Robinson]
9720 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9722 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9725 Changes with Apache 0.8.14 19 Sep 1995
9727 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9729 *) AddDescription works (better) [Ben Laurie]
9731 *) Leaves an intelligible error diagnostic when it can't set group
9732 privileges on standalone startup [Andrew Wilson]
9734 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9735 that machine, which claims to be BSD but does not support RLIMIT.
9738 *) gcc -Wall no longer complains about an unused variable when util.c
9739 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9741 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9743 Changes with Apache 0.8.13 07 Sep 1995
9745 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9747 *) Have built-in imagemap code recognize & honor Point directive [James
9750 *) Generate cleaner directory listings in directories with a mix of
9751 long and short filenames [Rob Hartill]
9753 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9755 *) Properly default ServerName for virtual servers [Robert Thau]
9757 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9758 Paul Richards and a cast of thousands...]
9760 *) On self-identified BSD systems (we don't try to guess any more),
9761 allocate a few extra file descriptors per virtual host with setrlimit,
9762 if we can, to avoid running out. [Randy Terbush]
9764 *) Write 22-character lock file name into buffer with enough space
9765 on startup [Konstantin Olchanski]
9767 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9770 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9772 *) Suppress -Wall warning by initializing variable in negotiation code
9773 [Tobias Weingartner]
9775 Changes with Apache 0.8.12 31 Aug 1995
9777 *) Doesn't pause three seconds after including a CGI script which is
9778 too slow to die off (this is done by not even trying to kill off
9779 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9780 after the entire document has been processed). [Robert Thau]
9782 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9784 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9786 *) Allows .htaccess files to override <Directory> sections naming the
9787 same directory [David Robinson]
9789 *) Removed an efficiency hack in sub_req_lookup_uri which was
9790 causing certain extremely marginal cases (e.g., ScriptAlias of a
9791 *particular* index.html file) to fail. [David Robinson]
9793 *) Doesn't log an error when the requested URI requires
9794 authentication, but no auth header line was supplied by the
9795 client; this is a normal condition (the client doesn't no auth is
9796 needed here yet). [Robert Thau]
9798 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9800 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9802 *) RFC931 code no longer passes out name of prior clients on current
9803 requests if the current request came from a server that doesn't
9804 do RFC931. [David Robinson]
9806 *) Configuration script accepts "Module" lines with trailing whitespace.
9809 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9811 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9813 Changes with Apache 0.8.11 24 Aug 1995
9815 *) Wildcard <Directory> specifications work. [Robert Thau]
9817 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9819 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9820 the file being requested itself, in addition to the directories leading
9821 up to it. [Robert Thau]
9823 *) Logs access failures due to symlink checks or invalid client address
9824 in the error log [Roy Fielding, Robert Thau]
9826 *) Symlink checks deal correctly with systems where lstat of
9827 "/path/to/some/link/" follows the link. [Thau, Fielding]
9829 *) Doesn't reset DirectoryIndex to 'index.html' when
9830 other directory options are set in a .htaccess file. [Robert Thau]
9832 *) Clarified init code and nuked bogus warning in mod_access.c
9835 *) Corrected several directives in sample srm.conf
9836 --- includes corrections to directory indexing icon-related directives
9837 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9838 icons for encodings right, and turning on AddEncoding by default).
9841 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9844 *) INSTALL & README mention "contributed modules" directory [Brian
9847 *) Fixed English in the license language... "for for" --> "for".
9850 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9851 mod_alias.c, merging it almost completely with handling of Alias, and
9852 adding a 'notes' field to the request_rec which allows the CGI module
9853 to discover whether the Alias module has put this request through
9854 ScriptAlias (which it needs to know for back-compatibility, as the old
9855 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9858 Changes with Apache 0.8.10 18 Aug 1995
9860 *) AllowOverride applies to the named directory, and not just
9861 subdirectories. [David Robinson]
9863 *) Do locking for accept() exclusion (on systems that need it)
9864 using a special file created for the purpose in /usr/tmp, and
9865 not the error log; using the error log causes real problems
9866 if it's NFS-mounted; this is known to be the cause of a whole
9867 lot of "server hang" problems with Solaris. [David Robinson;
9868 thanks to Merten Schumann for help diagnosing the problem].
9870 Changes with Apache 0.8.9 12 Aug 1995
9872 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9874 *) Nested includes see environment variables of the including document,
9875 for NCSA bug-compatibility (some sites have standard footer includes
9876 which try to print out the last-modified date). [Eric Hagberg/Robert
9879 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9880 URI as a CGI script, even if it would have been treated as something
9881 else if requested directly, for NCSA back-compatibility. (Note that
9882 this means that people who know the name of the script can see the
9883 code just by asking for it). [Robert Thau]
9885 *) New version of dbmmanage script included in support directory as
9888 *) Check if scoreboard file couldn't be opened, and say so, rather
9889 then going insane [David Robinson]
9891 *) POST to CGI works on A/UX [Jim Jagielski]
9893 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9895 *) NCSA server push works properly --- the Arena bug compatibility
9896 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9897 if you still want the workaround). [Rob Hartill]
9899 *) If client didn't submit any Accept-encodings, ignore encodings in
9900 content negotiation. (NB this will all have to be reworked anyway
9901 for the new HTTP draft). [Florent Guillaume]
9903 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9905 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9907 *) Give Redirect priority over Alias, for NCSA bug compatibility
9910 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9911 paralleling earlier bug fix for CGI [David Robinson]
9913 *) If DBM auth is improperly configured, report a server error and don't
9916 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9917 it seems to work well enough without it (even in a 10 hits/sec
9918 workout), and the overhead for the locking under A/UX is
9919 alarmingly high (though it is very low on other systems).
9920 [Eric Hagberg, Jim Jagielski]
9922 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9924 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9925 Behlendorf/Eric Hagberg]
9927 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9929 *) Compiles clean on NEXT [Rob Hartill]
9931 *) Compiles clean on SGI [Robert Thau]
9933 Changes with Apache 0.8.8 08 Aug 1995
9935 *) SunOS library prototypes now never included unless explicitly
9936 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9937 people using GNU libc on SunOS are screwed by prototypes for the
9940 (Those who wish to compile clean with gcc -Wall on a standard
9941 SunOS setup need the prototypes, and may obtain them using
9942 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9943 with nonstandard libraries are presumably competent to make their
9946 *) Strips trailing '/' characters off both args to the Alias command,
9947 to make 'Alias /foo/ /bar/' work.
9949 Changes with Apache 0.8.7 03 Aug 1995
9951 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9952 [reported by David Robinson]
9954 *) Compiles clean on OSF/1 [David Robinson]
9956 *) Added some of the more recent significant changes (AddLanguage stuff,
9957 experimental LogFormat support) to CHANGES file in distribution root
9960 Changes with Apache 0.8.6 02 Aug 1995
9962 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9963 (If you actually wanted a conditional GET which bypassed the cache, you
9964 couldn't get it). [Reported by Roy Fielding]
9966 *) Properly terminate headers on '304 Not Modified' replies to conditional
9967 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9968 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9970 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9972 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9973 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9974 and older versions don't set the __SUNPRO_C preprocessor variable). On
9975 all other systems, these are never used anyway. [Reported by Mark Cox].
9977 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9979 Changes with Apache 0.8.5 01 Aug 1995
9981 *) Added last-minute configurable log experiment, as optional module
9983 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9984 properly. (One-line fix to http_protocol.c).
9986 *) Work around bogus behavior when reloading from Netscape.
9987 It's Netscape's bug --- for some reason they expect a request with
9988 If-modified-since: to not function as a conditional GET if it also
9989 comes with Pragma: no-cache, which is way out of line with the HTTP
9990 spec (according to Roy Fielding, the redactor).
9992 *) Added parameter to set maximum number of server processes.
9994 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9997 *) IdentityCheck bugfix [Chuck Murcko].
9999 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
10001 *) More sample config file corrections; add extension to AddType for
10002 *.asis, move AddType generic description to its proper place, and
10003 fix miscellaneous typos. [ Alexei Kosut ]
10005 *) Deleted the *other* reference to the regents from the Berkeley
10006 legal disclaimer (everyplace).
10008 *) Nuked Shambhala name from src/README; had already cleaned it out
10009 of everywhere else.
10011 Changes with Apache 0.8.4
10013 *) Changes to server-pool management parms --- renamed current
10014 StartServers to MinSpareServers, created separate StartServers
10015 parameter which means what it says, and renamed MaxServers to
10016 MaxSpareServers (though the old name still works, for NCSA 1.4
10017 back-compatibility). The old names were generally regarded as
10018 too confusing. Also altered "docs" in sample config files.
10020 *) More improvements to default config files ---
10021 sample directives (commented out) for XBitHack, BindAddress,
10022 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
10023 defaults, AddTypes for send-as-is and imagemap magic types, and
10024 improvements to samples for DirectoryIndex [Alexei Kosut]
10026 *) Yet more improvements to default config files --- changes to
10027 Alexei's sample AddLanguage directives, and sample LanguagePriority
10028 [ Florent Guillaume ]
10030 *) Set config file locations properly if not set in httpd.conf
10033 *) Don't escape URIs in internal redirects multiple times; don't
10034 do that when translating PATH_INFO to PATH_TRANSLATED either.
10037 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
10039 Changes with Apache 0.8.3
10041 *) Edited distribution README to *briefly* summarize installation
10042 procedures, and give a pointer to the INSTALL file in the src/
10045 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
10046 recent NCSA distributions.
10048 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
10049 exist for the same directory, use both and don't segfault. [Reported
10052 *) Proper makefile dependencies [David Robinson]
10054 *) Note (re)starts in error log --- reported by Rob Hartill.
10056 *) Only call no2slash() after get_path_info() has been done, to
10057 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
10058 reported by Andrew Wilson, though this one is probably a real bug]
10060 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
10061 dump core when Referer is not supplied. [Randy Terbush]
10063 *) Lightly edited sample config files to refer people to our documentation
10064 instead of NCSA's, and to list Rob McCool as *original* author (also
10065 deleted his old, and no doubt non-functional email address). Would be
10066 nice to have examples of new features...
10068 Changes with Apache 0.8.2 19 Jul 1995
10070 *) Added AddLanuage code [Florent Guillaume]
10072 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
10074 *) All sorts of problems when MultiViews finds a directory. It would
10075 be nice if mod_dir.c was robust enough to handle that, but for now,
10076 just punt. [reported by Brian Behlendorf]
10078 *) Wait for all children on restart, to make sure that the old socket
10079 is gone and we can reopen it. [reported by Randy Terbush]
10081 *) Imagemap module is enabled in default Configuration
10083 *) RefererLog and UserAgentLog modules properly default the logfile
10086 *) Mark Cox's mod_cookies added to the distribution as an optional
10087 module (commented out in the default Configuration, and noted as
10088 an experiment, along with mod_dld). [Mark Cox]
10090 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
10092 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
10094 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
10096 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
10099 Changes with Apache 0.8.1
10101 *) New imagemap module [Randy Terbush]
10103 *) Replacement referer log module with NCSA-compatible RefererIgnore
10104 [Matthew Gray again]
10106 *) Don't mung directory listings with very long filenames.
10107 [Florent Guillaume]
10109 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
10111 *) New config script. See INSTALL for info. [Robert Thau]
10113 *) Scoreboard mechanism for regulating the number of extant server
10114 processes. MaxServers and StartServers defaults are the same as
10115 for NCSA, but the meanings are slightly different. (Actually,
10116 I should probably lower the MaxServers default to 10).
10118 Before asking for a new connection, each server process checks
10119 the number of other servers which are also waiting for a
10120 connection. If there are more than MaxServers, it quietly dies
10121 off. Conversely, every second, the root, or caretaker, process
10122 looks to see how many servers are waiting for a new connection;
10123 if there are fewer than StartServers, it starts a new one. This
10124 does not depend on the number of server processes already extant.
10125 The accounting is arranged through a "scoreboard" file, named
10126 /tmp/htstatus.*, on which each process has an independent file
10127 descriptor (they need to seek without interference).
10129 The end effect is that MaxServers is the maximum number of
10130 servers on an *inactive* server machine, but more will be forked
10131 off to handle unusually heavy loads (or unusually slow clients);
10132 these will die off when they are no longer needed --- without
10133 reverting to the overhead of full forking operation. There is a
10134 hard maximum of 150 server processes compiled in, largely to
10135 avoid forking out of control and dragging the machine down.
10136 (This is arguably too high).
10138 In my server endurance tests, this mechanism did not appear to
10139 impose any significant overhead, even after I forced it to put the
10140 scoreboard file on a normal filesystem (which might have more
10141 overhead than tmpfs). [Robert Thau]
10143 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
10146 *) Read .htaccess files even in directory with <Directory> section.
10147 (Former incompatibility noted on mailing list, now fixed). [Robert
10150 *) "HEAD /" gives the client a "Bad Request" error message, rather
10151 than trying to send no body *and* no headers. [Cliff Skolnick].
10153 *) Don't produce double error reports for some very obscure cases
10154 mainly involving auth configuration (the "all modules decline to
10155 handle" case which is a sure sign of a server bug in most cases,
10156 but also happens when authentication is badly misconfigured).
10159 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
10160 it's *for*, and this sort of thing really shouldn't be cluttering
10161 up the Makefile). [Robert Thau]
10163 *) Incidental code cleanups in http_main.c --- stop dragging
10164 sa_client around; just declare it where used. [Robert Thau]
10166 *) Another acc-related fix. (It doesn't like const char
10167 in some places...). [Mark Cox]
10169 Changes with Shambhala 0.6.1 13 Jul 1995
10171 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
10172 Also, fixed auth typo in http_protocol.c unmasked by this fix.
10174 *) Compiles clean with acc on SunOS [Paul Sutton]
10176 *) Reordered modules in modules.c so that Redirect takes priority
10177 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
10178 believe it or not, he has an actual site with a ScriptAlias and
10179 a Redirect declared for the *exact same directory*. Even *my*
10180 compatibility fetish wouldn't motivate me to fix this if the fix
10181 required any effort, but it doesn't, so what the hey.
10183 *) Fixed to properly default several server_rec fields for virtual
10184 servers from the corresponding fields in the main server_rec.
10185 [Cliff Skolnick --- 'port' was a particular irritant].
10187 *) No longer kills off nph- child processes before they are
10188 finished sending output. [Matthew Gray]
10190 Changes with Shambhala 0.6.0 10 Jul 1995
10192 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
10193 the connection to the client in an "aborted" state, but otherwise
10194 allow whatever handlers are running to clean up. hard_timeout()s
10195 abort the request in progress completely; anything not tied to some
10196 resource pool cleanup will leak. They're still around because I
10197 haven't yet come up with a more elegant way of handling
10198 timeouts when talking to something that isn't the client. The
10199 default_handler and the dir_handler now use soft timeouts, largely
10200 so I can test the feature. [Robert Thau]
10202 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
10203 the case of log handlers dying prematurely is probably handled VERY
10204 gracelessly at this point, and if the logger stops reading input,
10205 the server will hang. (It is known to correctly restart the
10206 logging process on server restart; this is (should be!) going through
10207 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
10208 script). [Robert Thau]
10210 *) asis files supported (new module). [Robert Thau]
10212 *) IdentityCheck code is compiled in, but has not been tested. (I
10213 don't know anyone who runs identd). [Robert Thau]
10215 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
10216 came in with the request, for NCSA bug-compatibility. [Robert Thau]
10218 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
10220 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
10221 as timeouts are not in scope. [Robert Thau]
10223 *) quoted-string args in config files now handled correctly (doesn't drop
10224 the last character). [Robert Thau; reported by Randy Terbush]
10226 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
10227 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
10229 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
10230 default default type); the former default default behavior when all
10231 type-checkers defaulted had been a core dump. [Paul Sutton]
10233 *) Copy filenames out of the struct dirent when indexing
10234 directories. (On Linux, readdir() returns a pointer to the same
10235 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
10237 Changes with Shambhala 0.5.3 [not released]
10239 *) Default response handler notes "file not found" in the error log,
10240 if the file was not found. [Cliff Skolnick].
10242 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
10243 code no longer sets up bogus PATH_INFO which fakes out the directory
10244 handler). [Cliff Skolnick]
10246 Changes with Shambhala 0.5.2 06 Jul 1995
10248 *) Changes to http_main.c --- root server no longer plays silly
10249 games with SIGCHLD, and so now detects and replaces dying
10250 children. Child processes just die on SIGTERM, without taking
10251 the whole process group with them. Potential problem --- if any
10252 child process refuses to die, we hang in restart.
10253 MaxRequestsPerChild may still not work, but it certainly works
10254 better than it did before this! [Robert Thau]
10256 *) mod_dir.c bug fixes: ReadmeName and HeaderName
10257 work (or work better, at least); over-long description lines
10258 properly terminated. [Mark Cox]
10260 *) http_request.c now calls unescape_url() more places where it
10261 should [Paul Sutton].
10263 *) More directory handling bugs (reported by Cox)
10264 Parent Directory link is now set correctly. [Robert Thau]
10266 Changes with Shambhala 0.5.1 04 Jul 1995
10268 *) Generalized cleanup interface in alloc.c --- any function can be
10269 registered with alloc.c as a cleanup for a resource pool;
10270 tracking of files and file descriptors has been reimplemented in
10271 terms of this interface, so I can give it some sort of a test.
10274 *) More changes in alloc.c --- new cleanup_for_exec() function,
10275 which tracks down and closes all file descriptors which have been
10276 registered with the alloc.c machinery before the server exec()s a
10277 child process for CGI or <!--#exec-->. CGI children now get
10278 started with exactly three file descriptors open. Hopefully,
10279 this cures the problem Rob H. was having with overly persistent
10280 CGI connections. [Robert Thau]
10282 *) Mutual exclusion around the accept() in child_main() --- this is
10283 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
10284 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
10285 This uses fcntl(F_SETLK,...) on the error log descriptor because
10286 flock() on that descriptor won't work on systems which have BSD
10287 flock() semantics, including (I think) Linux 1.3 and Solaris.
10289 This does work on SunOS (when the server is idle, only one
10290 process in the pool is waiting on accept()); it *ought* to work
10291 on the other systems. [Robert Thau]
10293 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
10295 *) sizeof(*sa_client) bugfix from [Rob Hartill]
10297 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
10299 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
10300 be unnecessary if I go to the revised timeout-handling scheme).
10303 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
10304 string) even if none came in with the request. [Robert Thau]
10306 *) CHANGES file added to distribution ;-).
10308 Changes with Shambhala 0.4.5
10310 *) mod_dld --- early dynamic loading support [rst]
10311 *) Add wildcard content handlers for XBITHACK; default_hander now
10312 invoked with that mechanism (as a handler hanging off mod_core) [rst]
10313 *) XBITHACK supported as a wildcard content-handler, and
10314 configurable at run-time (not just at compile time, as in the
10315 "patchy server" releases) [rst]
10317 Changes with Shambhala 0.4.4 30 Jun 1995
10319 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
10320 *) Handle Addtype x/y .z [rst, reported by Cox]
10322 Changes with Shambhala 0.4.3
10324 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10325 synonymous [rst, terbush]
10327 Changes with Shambhala 0.4.1 28 Jun 1995
10329 *) First-cut virtual host implementation; some refit in the config
10330 reading code, and log management, was necessary to support this [rst]
10331 *) Sub-pool machinery, originally added to avoid excessive storage
10332 allocation on listings of large directories (which turned out to
10333 be the problem that the 0.3 storage accounting was added to
10334 find). Subrequests and mod_dir changed to use subpools. [rst]
10335 *) More memory debugging --- free list consistency checks. [rst]
10336 *) Added err_headers to request_rec, with support elsewhere [rst]
10337 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10339 Changes with Shambhala 0.3 19 Jun 1995
10341 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10342 *) Don't compile in mod_ai_backcompat by default
10343 *) Switch name of server from Apache to Shambhala in Makefile
10344 *) Add some accounting routines to track memory usage in the pools,
10347 Changes with Shambhala 0.2
10349 *) Set DOCUMENT_ROOT CGI variable
10350 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10351 *) Add critical section protection to handling of cleanup structures
10353 *) Significant code reorg within the server core to group related
10354 functions together [rst]
10355 *) Correctly handle clients that hang up before sending any request
10357 *) Replace dying child processes. [rst]
10359 Changes with Shambhala 0.1 12 Jun 1995
10361 Major rewrite of the pre-existing "patchy server" codebase, by
10362 Robert Thau (rst). Significant portions of the server code, such
10363 as configuration-file handling and HTTP authentication support,
10364 were ripped out and rewritten from scratch. Code that was not
10365 completely rewritten was significantly altered.
10367 Major changes with this release include:
10369 *) Introduction of the module API; in request handling, the central
10370 machinery just dispatches to various modules, which actually do
10371 most of the work. Configuration handling is similar --- modules
10372 declare their own commands, and the central machinery just
10373 dispatches to them.
10375 API features from shambhala/0.1 were substantially unchanged in
10376 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10377 release, such as wildcard handlers and subpools, were added in
10378 subsequent Shambhala releases, and were also generally rst's
10381 *) This release included the following modules:
10383 mod_access (access control --- allow and deny directives),
10384 mod_alias (Alias and Redirect commands),
10385 mod_auth (straight HTTP authentication, based on flat-files)
10386 mod_auth_dbm (same, with dbm files)
10387 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10388 mod_common_log (CLF access logs; later renamed mod_log_common)
10389 mod_dir (directory indexing)
10390 mod_include (server-side includes)
10391 mod_mime (AddType directives)
10392 mod_negotiation (content negotiation)
10393 mod_userdir (support for users' public_html directories)
10395 It also included a mod_ai_backcompat, which was a private hack
10396 for back-compatibility with rst's own AI-lab servers.
10398 All of these modules were substantially complete, and functional
10399 or nearly so (a few, which implemented features not in use at
10400 Thau's site, required patches of a few lines).
10402 *) sub-request machinery, to allow modules to determine how other
10403 modules would assign MIME types to a given file, or optionally
10404 serve its content (this is heavily used by mod_dir, mod_include
10405 and mod_negotiation).
10407 *) Resource pool system for keeping track of memory allocated and
10408 files opened in service of a particular request. Much of the
10409 code in the modules (when they weren't rewrites) was adjusted to
10410 replace a pervasive convention of using fixed-size buffers on
10411 the stack with an equally pervasive convention of using memory
10412 allocated with palloc().
10414 *) Reorganization of data structures associated with a given
10415 request to eliminate use of global variables and the troublesome
10416 unmunge_name function (used in NCSA and early Apache releases to
10417 attempt to determine the URI which mapped to a given filename
10418 --- a difficult proposition, given that it is easy to produce
10419 setups in which multiple URIs map to the same file).
10421 *) Source files renamed and rearranged
10423 *) Very simple pre-forking behavior --- parent process forked off a
10424 fixed number of children, and then just waited for SIGHUP.
10426 *) Other more minor changes too numerous to list.
10428 This release included modified versions of a lot of code from the
10429 Apache 0.6.4 public release, plus an early pre-forking patch
10430 codeveloped by Robert Thau and Rob Hartill.
10432 Changes with Apache 0.7.3 20 Jun 1995
10434 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10435 were incorporated by Rob Hartill on the main branch while Robert Thau
10436 worked on the Shambhala rewrite above. Most were merged into the
10437 Shambala architecture after Apache 0.8.0.
10439 Changes with Apache 0.6.4 13 May 1995
10441 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10444 Changes with Apache 0.5.1 10 Apr 1995

10459 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10460 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
