1 Changes with Apache 2.0.25-dev
3 *) Fix a segfault when a numeric value was received for Host:.
6 *) Add a function ap_remove_input_filter. This is to match
7 up with ap_remove_output_filter. [Ryan Bloom]
9 *) Clean up location_walk, so that this step performs a minimum
10 amount of redundant effort (it must be run twice, but it will no
11 longer reparse all <Location > blocks when the request uri
12 hadn't changed.) [William Rowe]
14 *) Eliminate proxy: (and all other 'special') processing from the
15 ap_directory_walk() phase. Modules that want to use special
16 walk logic should refer to the mod_proxy map_to_location example,
17 with it's proxy_walk and proxysection implementation. This makes
18 either directory_walk flavor much more legible, since that phase
19 only runs against real <Directory > blocks.
22 *) Fix a security problem in mod_include which would allow
23 an SSI document to be passed to the client unparsed.
24 [Cliff Woolley, Brian Pane]
26 *) Introduce the map_to_storage hook, which allows modules to bypass
27 the directory_walk and file_walk for non-file requests. TRACE
28 shortcut moved to http_protocol.c as APR_HOOK_MIDDLE, and the
29 directory_walk/file_walk happen as APR_HOOK_VERY_LAST in core.c.
32 *) Add the ability for mod_include to add the INCLUDES filter
33 if the file is configured for the server-parsed handler.
34 This makes the configuration for .shtml files much easier
35 to understand, and allows mod_include to honor Apache 1.3
36 config files. Based on Doug MacEachern's patch to PHP
37 to do the same thing. [Ryan Bloom]
39 *) force OpenSSL to ignore process local-caching and to always
40 get/set/delete sessions using mod_ssl's callbacks
41 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
42 Geoff Thorpe <geoff@geoffthorpe.net>]
44 *) Make the worker MPM shutdown and restart cleanly. This also
45 cleans up some race conditions, and gets the worker using
46 pools more cleanly. [Aaron Bannert <aaron@clove.org>]
48 *) Implement CRYPTO_set_locking_callback() in terms of apr_lock
50 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
52 *) Fix for mod_include. Ryan's patch to check error
53 codes put a return in the wrong place. Also, the
54 include handler return code wasn't being checked.
55 I don't like macros with returns, so I converted
56 SPLIT_AND_PASS_PRETAG_BUCKETS into a function.
57 [Paul J. Reder <rederpj@raleigh.ibm.com>]
59 *) fix segv in mod_mime if no AddTypes are configured
60 [John Sterling <sterling@covalent.net>]
62 *) Enable ssl client authentication at SSL_accept time
63 [Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>]
65 *) Fix a segfault in mod_include when the original request has no
66 associated filename (e.g., we're filtering the error document for
67 a bad URI). [Jeff Trawick]
69 *) Fix a storage leak (a strdup() call) in mod_mime_magic. [Jeff Trawick]
71 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
72 of httpd is started and shuts down due to socket conflict. Moving the
73 call to ap_log_pid solves the problem.
75 *) Changed the late-1.3 log_config substitution %c to %X, to log the
76 status of the closed connection, as it conflicts with the far more
77 common, historical ssl logging directive %...{var}c. [William Rowe]
79 *) Added the common error/ tree to the build/install targets
80 (similar to the common icons/ tree) for the multi-language error
81 messages that Lars committed earlier. [William Rowe]
83 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
85 *) Added a default commented-out mod_ldap and mod_auth_ldap
86 configuration to httpd-std.conf and httpd-win.conf
89 *) Added documentation for mod_ldap and mod_auth_ldap.
92 *) Enabled negative caching on attribute comparisons in the LDAP cache.
93 Fixed a problem where the default cache TTL was set in milliseconds
94 not microseconds causing the cache to time out almost immediately.
97 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
98 module code to follow APR. [Graham Leggett]
100 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
101 cleaned up when the connection pool pool is cleaned up.
104 *) Fix a minor issue with Jeff Trawick's mod_include
105 patch. Without this patch, the code will just allocate
106 more bytes in get_combined_directive than are needed.
109 *) Added the LDAP authentication module mod_auth_ldap.
110 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
112 *) Added the LDAP cache and connection pooling module mod_ldap.
113 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
115 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
116 by allowing a module to disable itself if its prerequisites are not
117 met. [Justin Erenkrantz]
119 Changes with Apache 2.0.24
121 *) Fix a couple of issues in mod_include when the tag appeared at
122 offsets near 8192 in the file being parsed. [Jeff Trawick]
124 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
125 reached. [Jeff Trawick]
127 *) Numerous improvements to the Win32 build system. Introduced command line
128 builds without requiring .mak files for MSVC 6.0 and later versions.
129 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
132 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
133 reporting of uninstalled services and other error conditions, and changed the
134 default service name to Apache2. [William Rowe]
136 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
137 compatibility with existing Apache 1.3 Win32 Apache management utilites.
138 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
140 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
141 [William Rowe, Greg Ames]
143 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
144 and RemoveCharset directives. [William Rowe]
146 *) The Unix MPMs other than perchild now allow child server
147 processes to use the accept mutex when starting as root and
148 using SysV sems for the accept mutex. Previously, this
149 combination would lead to fatal errors in the child server
150 processes. perchild can't use SysV sems because of security
151 issues. [Jeff Trawick, Greg Ames]
153 *) Added Win32 revision stamp resources to all http binaries
154 (including modules/ and support/ tools.) PR7322 [William Rowe]
156 *) Fix ap_rvprintf to support more than 4K of data at one time.
157 [Cody Sherr <csherr@covalent.net>]
159 *) We have always used the obsolete/deprecated Netscape syntax
160 for our tracking cookies; now the CookieStyle directive
161 allows the Webmaster to choose the Netscape, RFC2109, or
162 RFC2965 format. The new CookieDomain directive allows the
163 setting of the cookie's Domain= attribute, too. PR #s 5006,
164 5023, 5920, 6140 [Ken Coar]
166 *) Tweak server/Makefile so that the rules for generating exports.c
167 are compatible with make utilities which don't expand wildcards
168 in a dependency list (e.g., OS/390 make, certain levels of GNU
169 make). [Jeff Trawick]
171 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
173 *) Begin to sanitize the MPM configuration directives. Now, all
174 MPMs use the same functions for all common MPM directives. This
175 should make it easier to catch all bugs in these directives once.
176 [Cody Sherr <csherr@covalent.net>]
178 *) Close a major resource leak. Every time we had issued a
179 graceful restart, we leaked a socket descriptor.
182 *) Fix a problem with the new method code. We need to cast
183 the 1 to an apr_int64_t or it will be treated as a 32-bit
184 integer, and it will wrap after being shifted 32 times.
185 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
187 *) Fix a bug in mod_expires. Previous to this patch, if you
188 told mod_expires to add 604800 seconds to the last-modified
189 time, it actually added 604800 usec's to the last-modified time,
190 so that when looking at the response it looked like nothing
191 had been done. The root of the problem was that we always compute
192 time in usec's, but we ask users to input sec's. This means we
193 need to convert to usec's before using those values.
196 *) The worker MPM now handles shutdown and restart requests. It
197 definitely isn't perfect, but we do stop the servers correctly.
198 The biggest problem right now is that SIGHUP causes the server to
199 just die. [Ryan Bloom]
201 Changes with Apache 2.0.23
203 *) Use the prefork MPM by default on Unix. [various]
205 *) Added a systray icon monitor application for Win32.
206 [Mladen Turk <mturk@mappingsoft.com>]
208 *) mod_rewrite: Fix the line ending on some non-Unix systems for
209 messages written to the rewrite log.
210 [Richard Labennett <rlabenn@us.ibm.com>]
212 *) All mod_autoindex query parsing is now quietly quashed with the
213 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
214 still drops the column sort <a href>'s for the column headers, but
215 IgnoreClient is required to ignore these Query options entirely.
218 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
219 to allow the client to select plain, FancyIndexing or HTMLTable
220 formatting, V=[0|1] to inhibit or enable version sorting, and
221 P=pattern to return only specific files. The old Query Arguments
222 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
223 as before), and O=A|D for ordering ascending or descending.
226 *) Fixed an error in mod_include's directive parsing routines which
227 caused #if, #elif, and #else expressions containing backslashes
228 to be improperly evaluated. [Cliff Woolley]
230 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
231 drop the icon column, SuppressRules to drop the <hr> elements,
232 and HTMLTable to create rudimentary HTML table listings (implies
233 FancyIndexing). [William Rowe]
235 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
236 from Apache 1.3.15. This is needed for two reasons, first, given
237 multiple machines within a server farm, ETags and Last-Modified
238 stamps won't correspond from machine to machine, and second, many
239 Unixes don't capture changes to the date or time stamp of existing
240 files, since these don't modify the dirent itself. [William Rowe]
242 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
243 and DirectoryWidth options from Apache 1.3.10.
244 [William Rowe, Ken Coar]
246 *) Eliminated FancyIndexing directive, deprecated early in Apache
247 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
249 *) mod_autoindex now excludes any file names that would result in
250 an error, other than a success or redirect. Also optimized
251 the parent directory, always included except in the URI '/'.
254 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
255 negotiated index pages, and prevent the server from defaulting
256 to an autoindex of the directory. mod_negotiation will now die
257 with a 500 Internal Error if it could match some filenames
258 (e.g. for mod_dir) but none can be served. mod_negotation now
259 refuses to serve any file with an extention that mod_mime doesn't
260 recognize, and wasn't part of the request. [William Rowe]
262 *) Eliminate mod_cgi's handling of .exe files without the .exe file
263 extension. This is already handled by multiviews, if the admin
264 wishes to AddHandler .exe or define a content type handler and
265 associate .exe files with that content type. Multiviews must be
266 enabled to allow these to be served. [William Rowe]
268 *) Speed up the server's response to a spike in incoming workload
269 or restarts by assigning empty scoreboard slots to new processes
270 when they are available. [Greg Ames]
272 *) Add a handler to mod_includes.c. This handler is designed to
273 implement the XbitHack directive. This can't be done with a
274 fixup, because we need to check the content-type, which is
275 only available in the handler phase. [Ryan Bloom]
277 *) Make the includes filter check return codes from filters lower in
278 the filter chain. If a lower level filter returns an error, then
279 the request needs to stop immediately. This allows mod_include to
280 stop parsing data once a lower filter recognizes an error.
283 *) Add the ability to extend the methods that Apache understands
284 and have those methods <limit>able in the httpd.conf. It uses
285 the same bit mask/shifted offset as the original HTTP methods
286 such as M_GET or M_POST, but expands the total bits from an int to
287 an ap_int64_t to handle more bits for new request methods than
288 an int provides. [Cody Sherr <csherr@covalent.net>]
290 *) Fix broken mod_mime behavior in merging its arguments. Possible
291 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
293 *) Solve many mod_ssl porting issues (too many to detail) with
294 help from the whole team, but most notably [Ralf S. Engelschall,
295 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
296 Doug MacEachern, William Rowe, Cliff Woolley]
298 *) More stall fixes for the threaded & worker mpm's.
299 Make mod_status output more accurate. Don't
300 count workers in processes which aren't actively
301 serving requests. [Greg Ames]
303 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
305 *) Add a single listener/multiple worker MPM. This MPM is
306 definately not fully correct, but it allows us to solve many
307 of the problems that exist in the threaded MPM. This is a
308 modified version of the threaded MPM. [Ryan Bloom]
310 *) Improve content generation throughout Apache, providing closer
311 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
312 Transitional specifications. [William Rowe]
314 Changes with Apache 2.0.22
316 *) Fix a problem where the threaded MPM stalls after restarts or
317 segfaults. Also prevent multiple active processes from using
318 the same scoreboard slot. [Greg Ames]
320 *) Apache/Win32 now fills in the service description with Apache's
321 server version string, including loaded and advertised modules.
324 *) Improved support for the Win32 build, to recover gracefully from
325 missing apr or apr-util directories or the awk interpreter,
326 create the proper cgi-bin examples, including a test-cgi.bat, and
327 fix the perl shebang line for printenv.pl, when installing from
328 the build environment. [William Rowe]
330 *) Fix a segfault in threaded.c caused by passing uninitialized
331 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
333 *) Use new APR number conversion functions to reduce CPU consumption
334 when setting the content length, and in mod_log_config.
337 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
338 where HEAD response headers were being repeated twice for
339 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
340 problem in the http_header filter was exposed by the recent rewrite
341 of the content_length filter. [Taketo Kabe, Bill Stoddard]
343 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
344 restarts. A garbage pointer to a vhost's server_rec from the
345 previous generation was being left around under certain
346 conditions. [Greg Ames]
348 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
349 used to appear as '(none', without the closing paren.
350 [Günter Knauf <eflash@gmx.net>]
352 *) Improve the exports generating awk script. In the past, we had
353 work around problems in the awk script by avoiding some #if and
354 #ifdefs. This has bitten us many times in generating the exports.c
355 file. This improvement allows corrects the header file parsing.
356 [Sander Striker <striker@apache.org>]
358 Changes with Apache 2.0.21
360 *) Resolve the Win32 htpasswd bug, where a file that existed would be
361 overwritten, regardless of the -c flag.
362 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
364 *) Introduce connection sub-pools into ab. Truncating the lifetime
365 of these allocations means that ab no longer perpetually grows
366 its working set, running out of memory on large request attempts.
369 *) Make scoreboard creation a hook. This allows management
370 modules to have access to the scoreboard at the time that it is
371 created, and at every restart request.
372 [Cody Sherr <csherr@covalent.net>]
374 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
375 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
376 daemon index actually used in the scoreboard. I also
377 updated the pertinent calls. [Paul J. Reder]
379 *) Win32: Prevent listening sockets from being inherited by
380 the Apache child process, CGI scripts, rotatelog process
381 etc. If the Apache child process segfaults, any processes
382 that the child started are not reaped. Prior to this fix,
383 these processes inherited the listening sockets which sometimes
384 prevented the restarted Apache child process from accepting
385 connections (ie, the server would hang).
388 *) Provide vhost and request strings when ExtendedStatus is on.
391 *) Fix some issues with the pod and prefork: check the pod *after*
392 processing a connection so that a server processing a time-
393 consuming request bails out as soon as practical; when the
394 parent process wakes up a server process via connect(), use an
395 APR timeout on the connect() so that we don't hang for a long
396 time if there aren't server processes around to do accept().
397 [Jeff Trawick, Greg Ames]
399 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
400 spends a lot of time in apr_table_get calls. Using the default
401 httpd.conf, the tables for languages and charsets are somewhat
402 large, so the time spent scanning them on each request is
403 significant. Replacing the tables with hash tables provides
404 a nice speedup. [Brian Pane <bpane@pacbell.net>]
406 *) Add two functions to allow modules to access random parts of the
407 scoreboard. This allows modules compiled for one MPM to access the
408 scoreboard, even if it the server was compiled for another MPM.
409 [Harrie Hazewinkel <harrie@covalent.net>]
411 Changes with Apache 2.0.20
413 *) Fix problem in content-length filter where the filter would
414 buffer all the output from a CGI before sending any bytes
415 down the filter stack to the network. This problem would cause
416 significant memory consumption if the CGIs generated
417 lots of bytes. [Bill Stoddard]
419 *) Get non-blocking CGI pipe reads working with the bucket brigades.
422 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
425 *) Fix a bug in the threaded MPM that would cause it to kill off all
426 workers immediately after starting if the number of workers started
427 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
429 Changes with Apache 2.0.19
431 *) Fix problem with threaded MPM. The problem was that if each child
432 process was busy serving a single long-lived request and the server
433 was sent a graceful restart signal, the server would stop serving
434 requests. This would happen because each child process would wait to
435 die until the last thread was done, and the parent wouldn't spawn any
436 new children until a process died. Now, the parent looks at the fact
437 that the children are dying gracefully, and starts new children.
438 Those new children only start enough threads to compliment the number
439 of threads in the other child process that shares the same spot in
440 the scoreboard. In this way, we make sure to never go over
441 MaxClients. [Ryan Bloom]
443 *) modified mod_negotiation and mod_autoindex to speed up by almost a
444 factor of two on apr_dir_read()-enhanced platforms, such as Win32
445 and OS2, by calling ap_sub_request_lookup_dirent() with the results
446 already provided by apr_dir_read(). [William Rowe]
448 *) mod_file_cache is now more robust to filtering and serves requests
449 slightly more efficiently. [Cliff Woolley]
451 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
452 Module was calling ap_rwrite() followed by ap_rflush() but the
453 served content was not being displayed in the browser. Inspection
454 of the output stream revealed that the first data chunk was
455 missing the trailing CRLF required by the RFC. [Bill Stoddard]
457 *) apxs no longer generates ap_send_http_header() in the example handler
459 *) Fix an ab problem which could cause a divide-by-zero exception
460 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
461 [Ian Holsman <ianh@cnet.com>]
463 *) Solve case-insensitive platforms' confusion about negotiated
464 filenames, allowing files of differnt case to match in choosing
465 the document to serve. [William Rowe]
467 *) Fix brokenness when ThreadsPerChild is higher than the built-in
468 limit. We left ap_threads_per_child at the higher value which
469 led to segfaults when doing certain scoreboard operations.
472 *) Fix seg faults and/or missing output from mod_include. The
473 default_handler was using the subrequest pool for files and
474 MMAPs, even though the associated APR structures typically
475 live longer than the subrequest. [Greg Ames]
477 *) Extend mod_setenvif to support specifying regular expressions
478 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
479 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
480 will cause HAVE_TS to be set if any of the request headers begins
481 with "TS" and has a value that begins with any character in the
482 set [a-z]. [Bill Stoddard]
484 *) httpd children now re-bind themselves to a random CPU on
485 multiprocessor systems on AIX via bindprocessor() in 2.0.
486 [Victor J. Orlikowski]
488 *) Fix htdigest. It would go into a loop in getline when adding
489 a second user. [Bill Stoddard]
491 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
493 *) Automatically generate httpd.exp for AIX.
494 DSOs now work again on AIX in 2.0
495 [Victor J. Orlikowski]
497 *) Add a new request hook, error_log. This phase allows modules
498 to act on the error log string _after_ it has been written
499 to the error log. The goal for this hook is to allow monitoring
500 modules to send the error string to the monitoring agent.
503 *) Modify mod_echo to make it use filters for input and output.
504 [Ryan Morgan <rmorgan@covalent.net>]
506 *) Extend mod_headers to support conditional driven Header
507 add, append and set. Use SetEnvIf to set an envar and conditionally
508 add/append/set headers based on this envar thusly:
510 SetEnvIf TSMyHeader value HAVE_TSMyHeader
511 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
513 If the request contains header "TSMyHeader: value" then header
514 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
517 *) Extend mod_headers to support using format specifiers on Header
518 add, append and set header values. Two format specifiers are supported:
520 %t - reports, in UTC microseconds since the epoch, when the
521 request was received.
523 %D - reports the time, in microseconds, between when the request was
524 received and the response sent.
527 Header add MyHeader "This request served in %D microseconds. %t"
529 results in a header being added to the response that looks like this:
531 MyHeader: This request served in D=5438 microseconds. t=991424704447256
535 *) Fix reset_filter(). We need to be careful how we remove filters.
536 If we set r->output_filters to NULL, we also have to reset the
537 connection's filters. [John Sterling]
539 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
541 *) Add a check to ap_die() to make sure the filter stack is sane and
542 contains the correct basic filters when an error occurs. This fixes
543 a problem where headers are not being sent on error. [John Sterling]
545 *) New Header directive 'echo' option. "Header echo regex" will
546 cause any headers received on the request that match regex to be
547 echoed to (included in) the response headers.
550 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
551 This prevented the inclusion of apr_compat.h. PR #7773
552 [Oleg Broytmann <phd@phd.pp.ru>]
554 *) Moved util_uri to the apr-util library. This required a bunch of
555 apr_name changes for the uri utility functions. [Justin Erenkrantz]
557 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
558 insert_filter phase so that other filters are not bypassed by default.
561 *) Reimplement mod_headers as an output filter. mod_headers can now
562 add custom headers to inbound requests using the RequestHeader directive
563 and to responses using the same old Header directive. [Graham Leggett]
565 Changes with Apache 2.0.18
567 *) Fix command-line processing so that if a bad argument is specified
568 Apache will exit. [Jeff Trawick]
570 *) Change the make targets and rules to be consistent in all of the
571 Apache-owned source trees. [Roy Fielding]
573 *) Fix processing of the TRACE method. Previously we passed bogus
574 parms to form_header_field() and it overlaid some vhost structures,
575 resulting in a segfault in check_hostalias().
576 [Greg Ames, Jeff Trawick]
578 *) Win32: Add support for reliable piped logs. If the logging process
579 goes down, Apache will automatically restart it. This function has
580 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
583 *) Do not start piped log processes during the config file
584 preflight. This change also circumvents a problem on
585 Windows where the rotatelog processes created during preflight
586 was not getting cleaned up properly.
589 *) add "Request Phase Participation" info to mod_info
592 *) Make first phase changes to the scoreboard data structures in
593 preparation for the rewriting of the scoreboard per my posted
594 design notes. [Paul J. Reder]
596 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
597 and apr-util, allow it to be overridden by the configure command-line
598 (default="--silent") and introduce LT_LDFLAGS to replace what we were
599 formerly abusing as LTFLAGS. [Roy Fielding]
601 *) Clean up the reporting of incorrect closing container tags.
602 [Barrie Slaymaker <barries@slaysys.com>]
604 *) Simplify the configure process by moving all libtool stuff to APR
605 and moving hints.m4 inline. [Roy Fielding]
607 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
608 of functions used by mod_proxy for export in the DLL
609 [Ian Holsman <IanH@cnet.com>]
611 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
612 request body from its stdin but no reqest body is being written to
613 the cgi. [Jeff Trawick]
615 *) mod_log_config: %c connection status incorrectly logged
616 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
619 *) Get mod_cern_meta working under Windows
622 *) Create Files, and thus MMAPs, out of the request pool, not the
623 connection pool. This solves a small resource leak that had us
624 not closing files until a connection was closed. In order to do
625 this, at the end of the core_output_filter, we loop through the
626 brigade and convert any data we have into a single HEAP bucket
627 that we know will survive clearing the request_rec.
628 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
631 *) Completely revamp configure so that it preserves the standard make
632 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
633 the configure additions to EXTRA_* variables. Also, allow the user
634 to specify NOTEST_* values for all of the above, which eliminates the
635 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
636 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
637 avoid pointless duplications. Fix the order in which flags are given
638 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
639 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
640 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
641 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
643 *) Get mod_tls to compile/work better on Windows. PR #7612
644 [Bernhard Schrenk <b.schrenk@improx.com>]
646 *) Fix shutdown/restart hangs in the threaded MPM.
647 [Jeff Trawick, Greg Ames, Ryan Bloom]
649 *) Removed the keptalive boolean from conn_rec because it is now only
650 used by a single routine and can be replaced by a local variable.
651 [Greg Stein, Ryan Bloom, Roy Fielding]
653 *) Patch prefork to put enough of the signal processing back in so that
654 signals are all handled properly now. The previous patch fixed the
655 deadlock race condition, but broke the user directed signal handling.
656 This fixes it to work the way it did before my previous prefork patch
657 (primarily, SIGTERM is now working).
659 *) Change how input filters decide how much data is returned to the
660 higher filter. We used to use a field in the conn_rec, with this
661 change, we use an argument to ap_get_brigade to determine how much
662 data is retrieved. [Ryan Bloom]
664 *) Fix seg fault at start-up introduced by Ryan's change to enable
665 modules to specify their own logging tags. mod_log_config
666 registers an optional function, ap_register_log_handler().
667 ap_register_log_handler() was being called by http_core before
668 the directive hash table was created. This patch creates the
669 directive hash table before ap_register_log_handler() is
670 registered as an optional function.
671 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
673 *) Add ap_set_int_slot() function
674 [John K. Sterling <sterling@covalent.net>]
676 *) Under certain circumstances, Apache did not supply the
677 right response headers when requiring authentication.
678 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
679 (This is a port of the change that went into Apache 1.3.19.)
681 *) Allow modules to specify their own logging tags. This basically
682 allows a module to tell mod_log_config that when %x is encountered
683 a specific function should be called. Currently, x can be any single
684 character. It may be more useful to make this a string at some point.
687 Changes with Apache 2.0.17
689 *) If a higher-level filter handles the the byterange aspects of a
690 request, then the byterange filter should not try to redo the
691 work. The most common case of this happening, is a byterange
692 request going through the proxy, and the origin server handles
693 the byterange request. The proxy should ignore it.
694 [Graham Leggett <minfrin@sharp.fm>]
696 *) Changed the threaded mpm to have child_main join to each of the
697 worker threads to make sure the kids are all gone before child_main
698 exits after a signal (cleanup from perform_idle_server_maintenance).
699 This is an extension of Ryans recent commit to make the child_main
702 *) Add more options to the ap_mpm_query function. This also allows MPMs to
703 report if their threads are dynamic or static. Finally, this also
704 implements a new API, ap_show_mpm, which returns the MPM that was
705 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
707 *) Do not install the binaries from the support directory twice.
708 [jun-ichiro hagino <itojun@iijlab.net>]
710 *) The ap_f* functions should flush data to the filter that is passed
711 in, not the the filter after the one passed in.
712 [Ryan Morgan <rmorgan@covalent.net>]
714 *) Make ab work again by changing its native types to apr types and formats.
715 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
717 *) Move the byterange filter and all of the supporting functions back
718 to the HTTP module. The byterange filter turned out to be very
719 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
721 *) Make clean, distclean, and extraclean consistently according to the
722 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
724 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
725 This may have been causing problems stopping processes in the threaded
728 *) Fix content-length in mod_negotiation to a long int representation.
731 *) Remove BindAddress from the default config file.
732 [giles@nemeton.com.au]
734 *) Allow module authors to add a module to their Apache build using
735 --with-module, without re-running buildconf. The syntax is:
736 --with-module=module_type:/path/to/module.c
737 The configure script will copy the module.c file to
738 modules/module_type, and it will be added to the relevant Makefiles.
739 currently, this only works for static modules. [Ryan Bloom]
741 *) Changes required to make prefork clean up idle children properly.
742 There was a window during which a starting worker deadlocks when
743 an idle cleanup arrives before it completes init. Apache then keeps
744 trying to cleanup the same deadlocked worker forever (until higher
745 pids come along, but it still will never reduce below the deadlocked
746 pid). Thus the number of children would not reduce to the correct
747 idle level. [Paul J. Reder]
749 Changes with Apache 2.0.16
751 *) Change the default installation directory to /usr/local/apache2,
752 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
754 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
757 *) Get MaxRequestsPerChild working with the Windows MPM.
760 *) Make generic hooks to work, with mod_generic_hook_import/export
761 experimental modules. [Ben Laurie, Will Rowe]
763 *) Fix segfaults for configuration file syntax errors such as
764 "<Directory>" followed by "</Directory" and
765 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
767 *) Cleanup the --enable-layout option of configure. This makes
768 us use a consistent location for the config.layout file, and it
769 makes configure more portable.
770 [jun-ichiro hagino <itojun@iijlab.net>]
772 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
773 csv/gnuplot format, rudimentary ssl support and various other tweaks
774 to make results more true to what is measured. The upshot of this it
775 turns out that 'ab' has often underreported the true performance of
776 apache. Often by a order of magnitude :-) See talk/paper of Sander
777 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
778 [Dirk-Willem van Gulik]
780 *) Clean up mod_cgid's temporary request pool. Besides fixing a
781 storage leak this ensures that some unnecessary pipes are closed.
784 *) Performance: Add quick_handler hook. This hook is called at the
785 very beginning of the request processing before location_walk,
786 translate_name, etc. This hook is useful for URI keyed content
787 caches like Mike Abbott's Quick Shortcut Cache.
790 *) top_module global variable renamed to ap_top_module [Perl]
792 *) Move ap_set_last_modified to the core. This is a potentially
793 controversial change, because this is kind of HTTP specific. However
794 many protocols should be able to take advantage of this kind of
795 information. I expect that headers will need one more layer of
796 indirection for multi-protocol work, but this is a small step in
797 the right direction. [Ryan Bloom]
799 *) Enable mod_status by default. This matches what Apache 1.3 does.
802 *) Add a ScriptSock directive to the default config file. This is
803 only enabled when mod_cgid is used.
804 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
806 Changes with Apache 2.0.15
808 *) Untangled the buildconf script and eliminated the need for build's
809 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
810 libtool muck that is now under srclib/apr/build. [Roy Fielding]
812 *) Win32: Don't accept more connections than we have worker threads
816 *) Fix bug in the Unix threaded.c MPM that allowed child processes
817 to fork() new child processes.
820 *) Fix a major security problem with double-reverse lookup checking.
821 Previously, a client connecting over IPv4 would not be matched
822 properly when the server had an IPv6 listening socket. PR #7407
823 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
825 *) Change the way the beos MPM handles polling to allow it to stop and
826 restart. Problem was the sockets being polled were being reset by
827 the select call, so once it had accepted a connection it was no
828 longer listening on the UDP socket we use for shutdown instructions.
829 APR needs to be altered, patch on it's way. [David Reid]
831 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
832 on error exit from ap_getline(). Some other code got upset because
833 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
835 *) Handle ap_discard_request_body() being called more than once.
836 [Greg Ames, Jeff Trawick]
838 *) Get rid of an inadvertent close of file descriptor 2 in
839 mod_mime_magic. [Greg Ames, Jeff Trawick]
841 *) Add a hook, create_request. This hook allows modules to modify
842 a request while it is being created. This hook is called for all
843 request_rec's, main request, sub request, and internal redirect.
844 When this hook is called, the the r->main, r->prev, r->next
845 pointers have been set, so modules can determine what kind of
846 request this is. [Ryan Bloom]
848 *) Cleanup the build process a bit more. The Apache configure
849 script no longer creates its own helper scripts, it just
851 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
853 *) Stop the forced downgrade of the connection to HTTP/1.0 for
854 proxy requests. [Graham Leggett]
856 *) Avoid using sscanf to determine the HTTP protocol number in
857 the common case because sscanf is a performance hog. From
858 Mike Abbot's Accelerating Apache patch number 6.
859 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
861 *) Fix a security exposure in mod_access. Previously when IPv6
862 listening sockets were used, allow/deny-from-IPv4-address rules
863 were not evaluated properly (PR #7407). Also, add the ability to
864 specify IPv6 address strings with optional prefix length on Allow
865 and Deny. [Jeff Trawick]
867 *) Enhance rotatelogs so that a UTC offset can be specified, and
868 the logfile name can be formatted using strftime(3). (Brought
869 forward from 1.3.) [Ken Coar]
871 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
872 DuplicateHandle on an IOCompletionPort (a practice which
873 MS "discourages"). The new model does not rely on associating
874 the completion port with the listening sockets, thus the
875 completion port can be completely managed within the child
876 process. A dedicated thread accepts connections off the network,
877 then calls PostQueuedCompletionStatus() to wake up worker
878 threads blocked on the completion port.
881 *) Bring forward the --suexec-umask option which allows the
882 builder to preset the umask for suexec processes. [Ken Coar]
884 *) Add a -V flag to suexec, which causes it to display the
885 compile-time settings with which it was built. (Only
886 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
888 *) Mod_include should always unset the content-length if the file is
889 going to be passed through send_parsed_content. There is no to
890 determine if the content will change before actually scanning the
891 entire content. It is far safer to just remove the C-L as long
892 as we are scanning it. [Ryan Bloom]
894 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
895 request and not Proxy-Authenticate.
896 [Graham Leggett <minfrin@sharp.fm>]
898 Changes with Apache 2.0.14
900 *) Fix content-length computation. We ONLY compute a content-length if
901 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
902 or we already have all the data. [Ryan Bloom]
904 *) Report unbounded containers in the config file. Previously, a typo
905 in the </container> directive could result in the rest of the config
906 file being silently ignored, with undesired defaults used.
909 *) Make the old_write filter use the ap_f* functions for the buffering.
912 *) Move more code from the http module into the core server. This
913 is core code, basically the default handler, the default input
914 and output filters, and all of the core configuration directives.
915 All of this code is required in order for the server to work, with or
916 without HTTP. The server is closer to working without the HTTP
917 module, although there is still more to do. [Ryan Bloom]
919 *) Fix a number of SGI compile warnings throughout the server. Fix some
920 bad parameters to apr_bucket_read(). Fix a bad statement in
921 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
922 consistently; we were mixing apr_time_t and time_t in invalid ways
923 before. In load_file(), call apr_dso_error() instead of
924 apr_strerror() so that we get a more specific string on some platforms.
925 PR #6980 [Jeff Trawick]
927 *) Allow modules to query the MPM about it's execution profile. This
928 query API can and should be extended in the future, but for now,
929 max_daemons, and threading or forking is a very good start.
930 [Jon Travis <jtravis@covalent.net>]
932 *) Modify mod_include to send blocks of data no larger than 9k.
933 Without this, mod_include will wait until the whole file is parsed,
934 or the first tag is found to send any data to the client.
935 [Paul J. Reder <rederpj@raleigh.ibm.com>]
937 *) Fix mod_info, so that <Directory> and <Location> directives are
938 not displayed twice when displaying the current configuration.
939 [Ryan Morgan <rmorgan@covalent.net>]
941 *) Add config directives to override DEFAULT_ERROR_MSG and
942 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
943 [Dan Rench <drench@xnet.com>]
945 *) Get mod_info building and loading on Win32. [William Rowe]
947 *) Begin to move protocol independant functions out of mod_http. The goal
948 is to have only functions that are HTTP specific in the http directory.
951 Changes with Apache 2.0.13
953 *) Don't assume that there will always be multiple calls to the byterange
954 filter. It is possible that we will need to do byteranges with only
955 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
957 *) Move the error_bucket definition from the http module to the
958 core server. Every protocol will need this ability, not just
961 Changes with Apache 2.0.12
963 *) Modify mod_file_cache to save pre-formatted strings for
964 content-length and last-modified headers for performance.
965 [Mike Abbot <mja@trudge.engr.sgi.com>]
967 *) Namespace protect IOBUFSIZ since it is exposed in the API.
968 [Jon Travis <jtravis@covalent.net>]
970 *) Use "Basic" authentication instead of "basic" in ab, as the spec
971 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
973 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
974 without ever filling it out. This fixes PR 7271.
975 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
976 Cliff Woolley <cliffwoolley@yahoo.com>]
978 *) Add a couple of GCC attribute tags to printf style functions.
979 [Jon Travis <jtravis@covalent.net>]
981 *) Add the correct language tag for interoperation with the Taiwanese
982 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
984 *) Migrate the perchild MPM to use the new apr signal child, and
985 APR thread functions. [Ryan Bloom]
987 *) Close one copy of the CGI's stdout before creating the new process.
988 The CGI will still have stdout, because we have already dup'ed it.
989 This keeps Apache from waiting forever to send the results of a CGI
990 process that has forked a long-lived child process.
991 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
993 *) Remove the rest of the pthreads functions from the threaded MPM.
994 This requires the APR support for a signal thread that was just
997 *) Make mod_dir use a fixup for sending a redirect to the browser.
998 Before this, we were using a handler, which doesn't make much
999 sense, because the handler wasn't generating any data, it would
1000 either return a redirect error code, or DECLINED. This fits the
1001 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
1003 *) Make the threaded MPM use APR threads instead of pthreads.
1006 *) Get mod_tls to the point where it actually appears to work in all cases.
1009 *) implement --enable-modules and --enable-mods-shared for "all" and
1010 "most". [Greg Stein]
1012 *) Move the threaded MPM to use APR locks instead of pthread locks.
1015 *) Rename mpmt_pthread to threaded. This is more in line with the
1016 fact that mpmt_pthread shouldn't be using pthreads directly, and
1017 it is a smaller name that doesn't tie into anything.
1020 *) Rename the module structures so that the exported symbol matches
1021 the file name, and it is easier to automate the installation
1022 process (generating LoadModule directives from the module filenames).
1025 *) Remove the coalesce filter. With the ap_f* functions, this filter
1026 is no longer needed. [Ryan Bloom]
1028 Changes with Apache 2.0.11
1030 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
1031 added feature of allowing a uid/gid per child process. If no
1032 uid/gid is specified, then Perchild behaves exactly like dexter.
1035 *) Get perchild building again. [Ryan Bloom]
1037 *) Don't disable threads just because we are using the prefork MPM.
1038 If somebody wants to compile without threads, they must now add
1039 --disable-threads to the configure command line. [Ryan Bloom]
1041 *) Begin to move the calls to update_child_status into common code, so
1042 that each individual MPM does not need to update the scoreboard itself.
1045 *) Allow mod_tls to compile under Unix boxes where openssl has been
1046 installed to the system include files.
1047 [Gomez Henri <new-httpd@slib.fr>]
1049 *) Cleanup the mod_tls configure process. This should remove any need
1050 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
1051 configure doesn't check that yet. [Ryan Bloom]
1053 *) Add a very early prototype of SSL support (in mod_tls.c). It is
1054 vital that you read modules/tls/README before attempting to build
1057 *) Fix a potential seg fault on all platforms. David Reid fixed this
1058 on BEOS, but the problem could happen anywhere, so we don't want
1059 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
1061 *) Add new LogFormat directive, %D, to log time it takes to serve a
1062 request in microseconds. [Bill Stoddard]
1064 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
1065 SetOutputFilter. This corresponds nicely with the other Set
1066 directives, which operate on containers while the Add* directives
1067 tend to work directly on extensions. [Ryan Bloom]
1069 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1070 functions for the buffering so that we don't need to compute
1071 the length of the headers before we actually create the header
1072 buffer. [Ryan Bloom]
1074 *) Allow filters to buffer data using the ap_f* functions. These have
1075 become macros that resolve directly to apr_brigade_*.
1078 *) Get the Unix MPM's to do a graceful restart again. If we are going
1079 to register a cleanup with ap_cleanup_scoreboard, then we have to
1080 kill the cleanup with the same function, and that function can't be
1081 static. [Ryan Bloom]
1083 *) Install all required header files. Without these, it was not
1084 possible to compile some modules outside of the server.
1087 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1088 forward from 1.3 to 2.0, we missed a single line, which broke regex
1089 aliases. [Ryan Bloom]
1091 *) We have a poor abstraction in the protocol. This is a temporary
1092 hack to fix the bug, but it will need to be fixed for real. If
1093 we find an error while sending out a custom error response, we back
1094 up to the first non-OK request and send the data. Then, when we send
1095 the EOS from finalize_request_protocol, we go to the last request,
1096 to ensure that we aren't sending an EOS to a request that has already
1097 received one. Because the data is sent on a different request than
1098 the EOS, the error text never gets sent down the filter stack. This
1099 fixes the problem by finding the last request, and sending the data
1100 with that request. [Ryan Bloom]
1102 *) Make the server status page show the correct restart time, and
1103 thus the proper uptime. [Ryan Bloom]
1105 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1106 should reduce the amount of duplicate code that is required to
1107 create CGI processes.
1108 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1110 *) ap_new_connection() closes the socket and returns NULL if a socket
1111 call fails. Usually this is due to a connection which has been
1112 reset. [Jeff Trawick]
1114 *) Move the Apache version information out of httpd.h and into release.h.
1115 This is in preparation for the first tag with the new tag and release
1116 system. [Ryan Bloom]
1118 *) Begin restructuring scoreboard code to enable adding back in
1119 the ability to use IPC other than shared memory.
1120 Get mod_status working on Windows again. [Bill Stoddard]
1122 *) Make mod_status work with 2.0. This will work for prefork,
1123 mpmt_pthread, and dexter. [Ryan Bloom]
1125 *) Correct a typo in httpd.conf.
1126 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1128 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1130 *) Get the correct IP address if ServerName isn't set and we can't
1131 find a fully-qualified domain name at startup.
1132 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1134 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1136 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1137 'extra' stat's for user/group since they should never occur, and now
1138 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1139 volumes. [William Rowe]
1141 *) Adopt apr features to simplify mod_includes. This changes the
1142 behavior of the USER_NAME variable, unknown uid's are now reported
1143 as USER_NAME="<unknown>" rather than the old user#000 result.
1144 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1146 *) Adopt apr features for simplifing mod_userdir, and accept the new
1147 Win32/OS2 exceptions without hiccuping. [William Rowe]
1149 *) Replace configure --with-optim option by using and saving the
1150 environment variable OPTIM instead. This is needed because configure
1151 options do not support multiple flags separated by spaces.
1154 *) Fix some byterange handling. If we get a byte range that looks like
1155 "-999999" where that is past the end of the file, we should return
1156 a PARTIAL CONTENT status code, and return the whole file as one big
1157 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1159 *) Make the error bucket a real meta-data bucket. This means that the
1160 bucket length is 0, and a read returns NULL data. If one of these
1161 buckets is passed down after the headers are sent, this data will
1162 just be ignored. [Greg Stein]
1164 *) The prefork MPM wasn't killing child processes correctly if a restart
1165 signal was received while the process was serving a request. The child
1166 process would become the equivalent of a second parent process. If
1167 we break out of the accept loop, then we need to do die after cleaning
1168 up after ourselves. [Ryan Bloom]
1170 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1171 restarts. [Ryan Bloom]
1173 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1174 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1175 performing very expensive owner, group and permission lookups
1176 and allows the server to function until these apr_finfo_t fields
1177 are implemented under Win32. [William Rowe]
1179 *) Support for typedsafe optional functions - that is functions exported by
1180 optional modules, which, therefore, may or may not be present, depending
1181 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1182 for sample code. [Ben Laurie]
1184 *) filters can now report an HTTP error to the server. This is done
1185 by sending a brigade where the first bucket is an error_bucket.
1186 This bucket is a simple bucket that stores an HTTP error and
1187 a string. Currently the string is not used, but it may be needed
1188 to output an error log. The http_header_filter will find this
1189 bucket, and output the error text, and then return
1190 AP_FILTER_ERROR, which informs the server that the error web page
1191 has already been sent. [Ryan Bloom]
1193 *) If we get an error, then we should remove all filters except for
1194 those critical to serving a web page. This fixes a bug, where
1195 error pages were going through the byterange filter, even though
1196 that made no sense. [Ryan Bloom]
1198 *) Relax the syntax checking of Host: headers in order to support
1199 iDNS. PR#6635 [Tony Finch]
1201 *) Cleanup the byterange filter to use the apr_brigade_partition
1202 and apr_bucket_copy functions. This removes a lot of very messy
1203 code, and hopefully makes this filter more stable.
1206 *) Remove AddModule and ClearModuleList directives. Both of these
1207 directives were used to ensure that modules could be enabled
1208 in the correct order. That requirement is now gone, because
1209 we use hooks to ensure that modules are in the correct order.
1212 *) When SuExec is specified, we need to add it to the list of
1213 targets to be built. If we don't, then any changes to the
1214 configuration won't affect SuExec, unless 'make suexec' is
1215 specifically run. [Ryan Bloom]
1217 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1218 the APR_XTHREAD argument to open a file for consumption by
1219 parallel threads on win32. [William Rowe]
1221 *) Correct a bug in determining when we follow symlinks. The code
1222 expected a stat -1 result, not an apr_status_t positive error.
1223 Also check if the APR_FINFO_USER fields are valid before we
1224 follow the link. [William Rowe]
1226 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1227 mpm_common.c. These functions are only valid on some platforms,
1228 so they should not be in the main-line code. [Ryan Bloom]
1230 *) Remove ap_chdir_file(). This function is not thread-safe,
1231 and nobody is currently using it. [Ryan Bloom]
1233 *) Do not try to run make depend if there are no .c files in the
1234 current directory, doing so makes `make depend` fail.
1237 *) Update highperformance.conf to work with either prefork or
1238 pthreads mpms. [Greg Ames]
1240 *) Stop checking to see if this is a pipelined request if we know
1241 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1242 This keeps us from making an extra read call when serving a 1.0
1243 request. [Ryan Bloom and Greg Stein]
1245 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1246 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1247 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1249 *) Fix the RFC number mentioned when complaining about a missing
1250 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1252 *) Fix an endless loop in ab which occurred when ab was posting
1253 and the server dropped the connection unexpectedly.
1256 *) Fix a segfault while handling request bodies in ap_http_filter().
1257 This problem has been seen with mod_dav usage as well as with
1258 requests where the body was just being discarded. [Jeff Trawick]
1260 *) Some adjustment on the handling and automatic setting (via
1261 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1262 add the capability to specify flags (NOTEST_CFLAGS and
1263 NOTEST_LDFLAGS) which are used to compile Apache, but
1264 not used during the configuration process. Useful for
1265 flags like "-Werror". [Jim Jagielski]
1267 *) Stop using environment variables to force debug mode or
1268 no detach. We now use the -D command line argument to
1269 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1270 [Greg Stein, Ryan Bloom]
1272 *) Change handlers to use hooks. [Ben Laurie]
1274 *) Stop returning copies of filenames from both apr_file_t and
1275 apr_dir_t. We pstrdup the filenames that we store in the
1276 actual structures, so we don't need to pstrdup the strings again.
1279 *) mod_cgi: Fix some problems where the wrong error value was being
1280 traced. [Jeff Trawick]
1282 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1285 *) Add generic hooks. [Ben Laurie]
1287 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1289 *) Fix a segfault caused by mod_ext_filter when the external filter
1290 program does not exist. [Jeff Trawick]
1292 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1293 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1294 was served through mod_charset_lite (or anything else that would
1295 create a transient bucket in this size range). ap_bucket_make_heap()
1296 silently failed (fixed), transient_setaside() discovered it, but
1297 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1299 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1300 is that some browsers send extra lines at the end of POST requests, and
1301 we don't want to delay sending data back to the user just because the
1302 browser isn't well behaved. [Ryan Bloom]
1304 *) Get SuEXEC working again. We can't send absolute paths to suExec
1305 because it refuses to execute those programs. SuEXEC also wasn't
1306 always recognizing configuration changes made using the autoconf
1309 *) Allow the buildconf process to find the config.m4 files in the correct
1310 order. Basically, we can now name config.m4 files as config\d\d.m4,
1311 and we will sort them correctly when inserting them into the build
1312 process. [Ryan Bloom]
1314 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1315 This also allows mod_cgid to use ap_os_create_priviledged_process,
1316 thus allowing for SuExec execution from mod_cgid. Currently, we do
1317 not support everything that standard SuExec supports, but at least
1318 it works minimally now. [Ryan Bloom]
1320 *) Allow SuExec to be configured from the ./configure command line.
1323 *) Update some of the docs in README and INSTALL to reflect some of
1324 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1326 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1327 need to call sendfile again. This gets us serving large files
1328 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1330 *) Get the support programs building cleanly again.
1331 [Cliff Woolley <cliffwoolley@yahoo.com>]
1333 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1334 current directory logic now backs up over bin/ to determine the
1335 server root from the Apache.exe path.
1337 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1338 loadable modules, dynamic libs are all named libfoo.dll, and the
1339 makefile.win populates the include, lib and libexec directories.
1341 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1342 Apache gets IPv6 listening sockets by default. Additionally, the
1343 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1344 numeric address strings (e.g., "Listen [fe80::1]:8080").
1347 *) Modify the install directory layout. Modules are now installed in
1348 modules/. Shared libraries should be installed in libraries/, but
1349 we don't have any of those on Unix yet. All install directories
1350 are modifyable at configure time. [Ryan Bloom]
1352 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1354 *) Get the functions in server/linked into the server, regardless of
1355 which modules linked into the server. This uses the same hack
1356 for Apache that we use for APR and apr-util to ensure all of the
1357 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1358 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1359 the scripts a bit easier.
1362 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1363 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1365 *) Get all of the auth modules to the point that they will install and
1366 be loadable into the server. Our new build/install mechanism expects
1367 that all modules will have a common name format. The auth modules
1368 didn't use that format, so we didn't install them properly.
1371 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1372 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1374 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1376 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1377 after the end of the response. [Ryan Bloom]
1379 *) Get byterange requests working with responses that do not have a
1380 content-length. Because of the way byterange requests work, we have to
1381 have all of the data before we can actually do the byterange, so we
1382 can compute the content-length in the byterange filter.
1385 *) Get exe CGI's working again on Windows.
1388 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1389 they keep track of whether or not their post config hook has been
1390 called before. Instead of a static variable (which is replaced when
1391 the DSO is loaded a second time), use userdata in the process pool.
1394 Changes with Apache 2.0a9
1396 *) Win32 now requires perl to complete the final install step for users
1397 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1398 and installs the conf, htdocs and htdocs/manual directories.
1401 *) Make mod_include use a hash table to associate directive tags with
1402 functions. This allows modules to implement their own SSI tags easily.
1403 The idea is simple enough, a module can insert it's own tag and function
1404 combination into a hash table provided by mod_include. While mod_include
1405 parses an SSI file, when it encounters a tag in the file, it does a
1406 hash lookup to find the function that implements that tag, and passes
1407 all of the relevant data to the function. That function is then
1408 responsible for processing the tag and handing the remaining data back
1409 to mod_include for further processing.
1410 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1412 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1413 fewer parameters: the local and remote socket addresses were removed
1414 from the parameter list because all required information is available
1415 via the APR socket. [Jeff Trawick]
1417 *) Distribution directory structure reorganized to reflect a
1418 normal source distribution with external install targets.
1421 *) The MPMs that need multiple segments of shared memory now create
1422 two apr_shmem_t variables, one for each shared memory allocation.
1423 the problem is that we can't determine how much memory will be required
1424 for shared memory allocations once we try to allocate more than one
1425 variable. The MM code automatically aligns the shared memory allocations,
1426 so we end up needing to pad the amount of shared memory we want based
1427 on how many variables will be allocated out of the shared memory segment.
1428 It is just easier to create a second apr_shmem_t variable, and two
1429 shmem memory blocks.
1432 *) Cleanup the export list a bit. This creates a single unified list of
1433 functions exported by APR. The export list is generated at configure
1434 time, and that list is then used to generate the exports.c file.
1435 Because of the way the export list is generated, we only export those
1436 functions that are valid on the platform we are building on.
1439 *) Enable logging the cookie with mod_log_config
1440 [Sander van Zoest <sander@covalent.net>]
1442 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1445 *) Added lib/aputil/ as a placeholder for utility functions which are not
1446 specific to the Apache HTTP Server (but do not make sense with APR).
1447 The first utility is "apu_dbm": a set of functions to work with DBM
1448 files. This first version can be compiled for SDBM or GDBM databases.
1451 *) Complete re-write of mod_include. This makes mod_include a filter that
1452 uses buckets directly. This has now served the FAQ correctly.
1453 [Paul Reder <rederpj@raleigh.ibm.com>]
1455 *) Allow modules to specify the first filter in a sub_request when
1456 making the sub_request. This keeps modules from having to change the
1457 output_filter immediately after creating the sub-request, and therefore
1458 skip the sub_req_output_filter. [Ryan Bloom]
1460 *) Update ab to accept URLs with IPv6 literal address strings (in the
1461 format described in RFC 2732), and to build Host header fields in
1462 the same format. This allows IPv6 literal address strings to be
1463 used with ab. This support has been tested against Apache 1.3 with
1464 the KAME patch, but Apache 2.0 does not yet work with this format
1465 of the Host header field. [Jeff Trawick]
1467 *) Accomodate an out-of-space condition in the piped logs and the
1468 rotatelogs.c code, and no longer churn log processes for this
1469 condition. [Victor J. Orlikowski]
1471 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1474 Changes with Apache 2.0a8
1476 *) Add a directive to mod_mime so that filters can be associated with
1480 *) Get multi-views working again. We were setting the path_info
1481 field incorrectly if we couldn't find the specified file.
1484 *) Fix 304 processing. The core should never try to send the headers
1485 down the filter stack. Always, just setup the table in the request
1486 record, and let the header filter convert it to data that is ready
1490 *) More fixes for the proxy. There are still bugs in the proxy code,
1491 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1495 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1498 *) APR: Add new apr_getopt_long function to handle long options.
1499 [B. W. Fitzpatrick <fitz@red-bean.com>]
1501 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1502 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1503 hostname resolution/address string parsing and building
1504 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1505 of one of the apr_sockaddr_t structures for a socket. Change
1506 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1508 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1509 I have proxied pages with it, cleanup will commence soon.
1512 *) Make the proxy work with filters. This isn't perfect, because we
1513 aren't dealing with the headers properly. [Ryan Bloom]
1515 *) Do not send a content-length iff the C-L is 0 and this is a head
1516 request. [Ryan Bloom]
1518 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1519 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1521 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1523 *) Get the default_handler to stop trying to deal with HEAD requests.
1524 The idea is to let the content-length filter compute the C-L before
1525 we try to send the data. If we can get the C-L correctly, then we
1526 should send it in the HEAD response.
1529 *) The Header filter can now determine if a body should be sent based
1530 on r->header_only. The general idea of this is that if we delay
1531 deciding to send the body, then we might be able to compute the
1532 content-length correctly, which will help caching proxies to cache
1533 our data better. Any handler that doesn't want to try to compute
1534 the content-length can just send an EOS bucket without data and
1535 everything will just work.
1538 *) Add the referer to the error log if one is available.
1539 [Markus Gyger <mgyger@itr.ch>]
1541 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1542 change, the root of the configuration tree has been exposed to modules
1544 [Ryan Morgan <rmorgan@covalent.net>]
1546 *) Get the core_output_filter to use the bucket interface directly.
1547 This keeps us from calling the content-length filter multiple times
1548 for a simple static request.
1551 *) We are sending the content-type correctly now.
1552 [Ryan Bloom and Will Rowe]
1554 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1555 a bogus bytes-sent value when the only thing being sent was trailers
1556 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1558 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1559 hints file to determine which platforms define
1560 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1563 *) APR: add apr_get_home_directory() [Jeff Trawick]
1565 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1567 *) Not all platforms have INADDR_NONE defined by default. Apache
1568 used to make this check and define INADDR_NONE if appropriate,
1569 but APR needs the check too, and I suspect other applications will
1570 as well. APR now defines APR_INADDR_NONE, which is always a valid
1571 value on all platforms.
1572 [Branko Èibej <brane@xbc.nu>]
1574 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1575 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1577 *) Relax the syntax checking of Host: headers in order to support
1578 iDNS. PR#6635 [Tony Finch]
1580 *) When reading from file buckets we convert to an MMAP if it makes
1581 sense. This also simplifies the default handler because the
1582 default handler no longer needs to try to create MMAPs.
1585 *) BUFF has been removed from the main server. The BUFF code will remain
1586 in the code until it has been purged from the proxy module as well.
1589 *) Byteranges have been completely re-written to be a filter. This
1590 has been tested, and I believe it is working correctly, but it could
1591 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1592 the output from 1.3, the only difference being that 1.3 includes
1593 a content-length in the response, and this does not.
1596 *) APR read/write functions and bucket read functions now operate
1597 on unsigned integers, instead of signed ones. It doesn't make
1598 any sense to use signed ints, because we return the error codes,
1599 so if we have an error we should report 0 bytes read or written.
1602 *) Always compute the content length, whether it is sent or not.
1603 The reason for this, is that it allows us to correctly report
1604 the bytes_sent when logging the request. This also simplifies
1605 content-length filter a bit, and fixes the actual byte-reporing
1606 code in mod_log_config.c
1609 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1610 it says, because it was only used by EOS and FLUSH buckets. Since
1611 neither of those are required at the end of a brigade, this was
1612 really signifying FLUSH_THE_DATA, but that can be determined better
1613 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1614 buckets now return a length of 0, which is actually the amount of data
1615 read, so they make more sense.
1618 *) Allow the core_output_filter to save some data past the end of a
1619 request. If we get an EOS bucket, we only send the data if it
1620 makes sense to send it. This allows us to pipeline request
1621 responses. As a part of this, we also need to allocate mmap
1622 buckets out of the connection pool, not the request pool. This
1623 allows the mmap to outlive the request.
1626 *) Make blocking and non-blocking bucket reads work correctly for
1627 sockets and pipes. These are the only bucket types that should
1628 have non-blocking reads, because the other bucket types should
1629 ALWAYS be able to return something immediately.
1632 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1633 server, but use Ctrl+Break to initiate a graceful restart
1634 instead of duplicating behavior. [John Sterling]
1636 *) Patch mod_autoindex to set the Last-Modified header based on
1637 the directory's mtime, and add the ETag header. [William Rowe]
1639 *) Merge the 1.3 patch to add support for logging query string in
1640 such a way that "%m %U%q %H" is the same as "%r".
1643 *) Port three log methods from mod_log_config 1.3 to 2.0:
1644 CLF compliant '-' byte count, method and protocol.
1647 *) Add a new LogFormat directive, %c, that will log connection
1648 status at the end of the response as follows:
1649 'X' - connection aborted before the response completed.
1650 '+' - connection may be kept-alive by the server.
1651 '-' - connection will be closed by the server.
1654 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1655 Unicode file names and paths for Win32, and tag the Content-Type
1656 from mod_autoindex to reflect that charset if the the feature
1657 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1659 *) Compute the content length (and add appropriate header field) for
1660 the response when no content length is available and we can't use
1661 chunked encoding. [Jeff Trawick]
1663 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1664 so that content input filters get dechunked data when using
1665 the default handler. Also removed REQUEST_CHUNKED_PASS.
1668 *) Add mod_ext_filter as an experimental module. This module allows
1669 the administrator to use external programs as filters. Currently,
1670 only filtering of output is supported. [Jeff Trawick]
1672 *) Most Apache functions work on EBCDIC machines again, as protocol
1673 data is now translated (again). [Jeff Trawick]
1675 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1676 the EBCDIC support. They are noops on ASCII machines, so this
1677 type of translation doesn't have to be surrounded by #ifdef
1678 CHARSET_EBCDIC. [Jeff Trawick]
1680 *) Fix mod_include. tag commands work again, and the server will
1681 send the FAQ again. This also allows mod_include to set aside
1682 buckets that include partial buckets.
1683 [Ryan Bloom and David Reid]
1685 *) Add suexec support back. [Manoj Kasichainula]
1687 *) Lingering close now uses the socket directly instead of using
1688 BUFF. This has been tested, but since all we can tell is that it
1689 doesn't fail, this needs to be really hacked on.
1692 *) Allow filters to modify headers and have those headers be sent to
1693 the client. The idea is that we have an http_header filter that
1694 actually sends the headers to the network. This removes the need
1695 for the BUFF to send headers.
1698 *) Charset translation: mod_charset_lite handles translation of
1699 request bodies. Get rid of the xlate version of ap_md5_digest()
1700 since we don't compute digests of filtered (e.g., translated)
1701 response bodies this way anymore. (Note that we don't do it at
1702 all at the present; somebody needs to write a filter to do so.)
1705 *) Input filters and ap_get_brigade() now have a input mode parameter
1706 (blocking, non-blocking, peek) instead of a length parameter.
1709 *) Update the mime.types file to the registered media types as
1710 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1713 *) Namespace protect some macros declared in ap_config.h
1716 *) Support HTTP header line folding with input filtering.
1719 *) Mod_include works again. This should still be re-written, but at
1720 least now we can serve an SHTML page again.
1723 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1724 to both the BUFF and the socket in the conn_rec. Functions that
1725 want to use the BUFF can, functions that want to use the socket,
1726 can. They point to the same place.
1729 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1730 [Tomas "Ögren" <stric@ing.umu.se>]
1732 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1733 associated pool goes away. (APR pipes on OS/2 were already had this
1734 logic.) This resolvs a fatal file descriptor leak with CGIs.
1737 *) The final line of the config file was not being read if there was
1738 no \n at the end of it. This was caused by apr_fgets returning
1739 APR_EOF even though we had read valid data. This is solved by
1740 making cfg_getline check the buff that was returned from apr_fgets.
1741 If apr_fgets return APR_EOF, but there was data in the buf, then we
1742 return the buf, otherwise we return NULL.
1745 *) Piped logs work again in the 2.0 series.
1748 *) Restore functionality broken by the mod_rewrite security fix:
1749 rewrite map lookup keys and default values are now expanded
1750 so that the lookup can depend on the requested URI etc.
1751 PR #6671 [Tony Finch]
1753 *) Tighten up the syntax checking of Host: headers to fix a
1754 security bug in some mass virtual hosting configurations
1755 that can allow a remote attacker to retrieve some files
1756 on the system that should be inaccessible. [Tony Finch]
1758 *) Add a pool bucket type. This bucket is used for data allocated out
1759 of a pool. If the pool is cleaned before the bucket is destroyed, then
1760 the data is converted to a heap bucket, allowing it to survive the
1764 *) Add a flush bucket. This allows modules to signal that the filters
1765 should all flush whatever data they currently have. There is no way
1766 to actually force them to do this, so if a filter ignores this bucket,
1767 that's life, but at least we can try with this.
1770 *) Add an output filter for sub-requests. This filter just strips the
1771 EOS bucket so that we don't confuse the main request's core output
1772 filter by sending multiple EOS buckets. This change also makes sub
1773 requests start to send EOS buckets when they are finished.
1776 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1777 makes ap_bucket_destroy a return void, which is okay because it
1778 used to always return APR_SUCCESS, and nobody ever checked its
1779 return value anyway.
1780 [Cliff Woolley <cliffwoolley@yahoo.com>]
1782 *) Remove the index into the bucket-type table from the buckets
1783 structure. This has now been replaced with a pointer to the
1784 bucket_type. Also add some macros to test the bucket-type.
1787 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1788 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1789 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1790 All _VAR_ flavors changes to _DATA to be absolutely clear.
1793 *) Add support for /, //, //servername and //server/sharename
1794 parsing of <Directory> blocks under Win32 and OS2.
1795 [Tim Costello, William Rowe, Brian Harvard]
1797 *) Remove the function pointers from the ap_bucket type. They have been
1798 replaced with a global table. Modules are allowed to register bucket
1799 types and use then use those buckets.
1802 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1803 once we finish writing the request body to the cgi child process;
1804 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1805 worked without this change (for reasons I don't understand), but large
1806 ones didn't. [Jeff Trawick]
1808 *) Remove file bucket specific information from the ap_bucket type.
1809 This has been moved to a file_bucket specific type that hangs off
1810 the data pointer in the ap_bucket type.
1813 *) Input filtering now has a third argument. This is the amount of data
1814 to read from lower filters. This argument can be -1, 0, or a positive
1815 number. -1 means give me all the data you have, I'll deal with it and
1816 let you know if I need more. 0 means give me one line and one line
1817 only. A positive number means I want no more than this much data.
1819 Currently, only 0 and a positive number are implemented. This allows
1820 us to remove the remaining field from the conn_rec structure, which
1824 *) Big cleanup of the input filtering. The goal is that http_filter
1825 understands two conditions, headers and body. It knows where it is
1826 based on c->remaining. If c->remaining is 0, then we are in headers,
1827 and http_filter returns a line at a time. If it is not 0, then we are
1828 in body, and http_filter returns raw data, but only up to c->remaining
1829 bytes. It can return less, but never more.
1830 [Greg Ames, Ryan Bloom, Jeff Trawick]
1832 *) mod_cgi: Write all of the request body to the child, not just what
1833 the kernel would accept on the first write. [Jeff Trawick]
1835 *) Back out the change that moved the brigade from the core_output_filters
1836 ctx to the conn_rec. Since all requests over a given connection
1837 go through the same core_output_filter, the ctx pointer has the
1841 *) Fix another bug in the send_the_file() read/write loop. A partial
1842 send by apr_send would cause unsent data in the read buffer to
1843 get clobbered. Complete making send_the_file handle partial
1844 writes to the network.
1847 *) Fix a couple of type fixes to allow compilation on AIX again
1848 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1850 *) Fix bug in send_the_file() which causes offset to be ignored
1851 if there are no headers to send.
1854 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1855 filter. Useful for supporting Windows 9* with a binary
1856 compiled on Windows NT.
1859 Changes with Apache 2.0a7
1861 *) Reimplement core_output_filter to buffer/save bucket brigades
1862 across multiple calls to the core_filter. The brigade will be
1863 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1864 thresholds are hit or the EOS bucket is received.
1867 *) Create experimental filter (buffer_filter) that coalesces bytes
1868 into one large buffer before invoking the next filter in the
1869 chain. This filter is particularly useful with the current
1870 implementation of mod_autoindex when it inserted above the
1871 chunk_filter. mod_autoindex generates a lot of brigades that
1872 containing buckets holding just a few bytes each. The
1873 buffer_filter coalesces these buckets into a single large bucket.
1876 *) Add apr_sendfile() support into the core_output_filter.
1879 *) Add apr_sendv() support into the core_output_filter.
1882 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1883 [Mike Abbott <mja@sgi.com>]
1885 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1886 make much sense, because Apache uses buckets instead of BUFFs now.
1889 *) send_the_file now falls back to a read/write loop on platforms that
1890 do not have sendfile.
1891 [Ryan Bloom and Brian Havard]
1893 *) Install apachectl correctly, and substitute the proper values so
1894 that it works again. [Ryan Bloom]
1896 *) Better(??) handle platforms that lack sendfile().
1899 *) APR now has UUID generation/formatting/parsing support.
1902 *) Begin the http_filter. This is an input filter that understands
1903 the absolute basic amount required to parse an HTTP Request. The
1904 goal is to be able to split headers from request body before passing
1905 the data back to the other filters.
1908 *) Bring forward from 1.3.13 the config directory implementation
1911 *) install apxs if it is created
1914 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1915 conversions. [William Rowe]
1917 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1918 ap_add_output_filter(). [Jeff Trawick]
1920 *) Multiple build and configuration fixes
1923 -add datadir and localstatedir substitutions
1925 -fix logfilename misspelling
1926 -fix evaluation of installation dir variables and
1927 -replace $foobar by $(foobar) to be usefull in the makefile
1931 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1932 $CC_FOR_BUILD is still missing
1933 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1934 -add missing "AR=@AR@" to severaly Makefile.in's
1935 -cache result for "struct rlimit"
1936 -compile all helper programs with native and cross compiler
1937 and use the native version to generate header file
1938 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1940 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1942 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1944 *) Fix a bug where a client which only sends \n to delimit header
1945 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1946 message. Start working on ebcdic co-existance with input
1948 [William Rowe, Greg Ames]
1950 *) If mod_so is enabled in the server always create libexec, even
1951 if there are no modules installed in this directory. This is a
1952 requirement for APXS to work correctly.
1955 *) Connection oriented output filters are now stored in the
1956 conn_rec instead of the request_rec. This allows us to add the
1957 output filter in the pre-connection phase instead of the
1958 post_read_request phase, which keeps us from trying to write an
1959 error page before we have a filter to write to the network.
1960 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1962 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1963 mmap can be used across multiple buckets (default_handler with
1964 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1965 the mmap itself can't be associated with the bucket.
1968 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1971 *) Radical surgery to improve mod_isapi support under Win32.
1972 Includes a number of newer ServerSupportFunction calls, support
1973 for ReadClient (in order to retrieve POSTs greater than 48KB),
1974 and general bug fixes to more reliably load ISAPI .dll's and
1975 prevent leaking handle resources. Note: There are still
1976 discrepancies between IIS's and Apache's ServerVariables, and
1977 async calls are still not supported. Additional warnings are
1978 logged to facilitate debugging of unsupported ISAPI calls.
1981 *) Add input filtering to Apache. The basic idea for the input
1982 filters is the same as the ideas for output filters. The biggest
1983 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1984 should be called, and the order of execution for the filter itself is
1985 different. When writing an output filter, a brigade is passed in,
1986 and filters operate directly on that brigade, when done, they call
1987 ap_pass_brigade. Input filters are the exact opposite. Because input
1988 is not a push operation, filters first call ap_get_brigade. When this
1989 function returns, the input filter will be left with a valid brigade.
1990 The input filter should then operate on the brigade, and return.
1993 *) Fix building on BSD/OS using its native make. The build system
1994 falls back to the BSD .include directive on that host platform.
1997 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1998 SHA1 and plaintext password encodings. Make feature tests a
1999 bit more flexible. [William Rowe]
2001 *) Charset translation: mod_charset_lite handles output content
2002 translation in a filter. mod_charset_lite no longer ignores
2003 subrequests. A bunch of cruft related to BUFF's support for
2004 translating request and response bodies was removed.
2007 *) Move the addition of the CORE filter to the post_read_request
2008 hook in http_core.c. This removes the need to add the filter in
2009 multiple places and allows for an SSL module to be added much
2010 simpler. [Ryan Bloom]
2012 *) Fix a security problem that affects certain configurations of
2013 mod_rewrite. If the result of a RewriteRule is a filename that
2014 contains expansion specifiers, especially regexp backreferences
2015 $0..$9 and %0..%9, then it may be possible for an attacker to
2016 access any file on the web server. [Tony Finch]
2018 *) Fix a bug where errors that are detected during early request parsing
2019 don't produce visible HTTP error messages at the browser, because
2020 the core_filter wasn't present. [Greg Ames]
2022 *) Provide apr_socklen_t as a portability aid.
2023 [Victor J. Orlikowski]
2025 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
2026 as well as a comment arg to the add, adduser and update cmds.
2027 update allows the user to clear or preserve pw/groups/comment.
2028 Fixed a bug in dbmmanage that prevented the check option from
2029 parsing a password followed by :group... text. Corrected the
2030 seed calcualation for Win32 systems, and added -lsdbm support.
2033 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
2036 *) Avoid a segfault when parsing .htaccess files. An
2037 uninitialized tree pointer was passed to ap_build_config().
2040 *) Change the way that inet_addr & inet_network are checked for
2041 in APR's configure process to allow BeOS BONE to correctly
2042 find them. With this change BeOS BONE now builds from source
2043 with no problems. [David Reid]
2045 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
2046 the end of the parameters to execve() was stored in the wrong
2047 location, overlaying the storage beyond the newargs[] array and
2048 also passing uninitialized storage to execve(), which would
2049 sometimes fail with EFAULT. [Jeff Trawick]
2051 *) Fix a bug parsing configuration file containers. With a sequence
2052 like this in the config file
2054 <IfModule mod_kilroy.c>
2057 <IfModule mod_lovejoy.c>
2062 the second container would be terminated at the blank line due to
2063 sediment in the buffer from reading the prior </IfModule> and an
2064 error message would be generated for the real </IfModule> for the
2065 second container. Also due to this problem, any two characters
2066 could be used for "</" in the close of a container.
2069 *) ap_add_filter prototype changed to remove the ctx pointer. The
2070 pointer still remains in the filter structure, but it can not be
2071 a part of the ap_add_filter prototype. The reason is that when
2072 the core uses AddFilter to add a filter to the stack it doesn't
2073 know how to allocate the ctx pointer, or even how much memory should
2074 be allocated. The filters will have to be responsible for allocating
2075 the ctx memory when they need it.
2078 *) Add an AddFilter directive. This directive takes a list of filters
2079 that should be activated for the requested resource.
2082 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2083 some other platforms). [Jeff Trawick]
2085 *) Modify mod_include to be a filter. Currently, it has only been tested
2086 on actual files, but it should work for CGI scripts too.
2089 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2090 writes. apr_flush() for Unix: handle interrupted writes.
2093 *) NameVirtualHost can now take "*" as an argument instead of
2094 an IP address. This allows you to create a purely name-based
2095 virtual hosting server that does not have any IP addresses in
2096 the configuration file and which ignores the local address
2097 of any connections. PR #5595, PR #4455 [Tony Finch]
2099 *) Fix some compile warnings in mod_mmap_static.c
2100 [Mike Abbott <mja@sgi.com>]
2102 *) Fix chunking problem with CGI scripts. The general problem was that
2103 the CGI modules were adding an EOS bucket and then the core added an
2104 EOS bucket. The chunking filter finalizes the chunked response when it
2105 encounters an EOS bucket. Because two EOS buckets were sent, we
2106 finalized the response twice. The fix is to make sure we only send one
2107 EOS, by utilizing a flag in the request_rec.
2110 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2111 and Win32. Previously, the first read from an apr_file_t set up via
2112 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2114 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2115 bucket, instead of using BUFF's and ap_r*.
2118 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2119 [Mike Abbott <mja@sgi.com>]
2121 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2122 code to use APR file's directly instead of going through BUFFs.
2125 *) Fix compile break on some platforms for mod_mime_magic.c
2126 [John K. Sterling <sterling@covalent.net>]
2128 *) Fix merging of AddDefaultCharset directive.
2129 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2131 *) Minor revamp of the rlimit sections of code. We now test
2132 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2133 is now "available" even if the platform doesn't support
2134 the rlimit family (it's just a noop though). [Jim Jagielski]
2136 *) Migrate the pre-selection of which MPM to use for specific
2137 platforms to hints.m4, which contains (or should contain)
2138 all platform specific "hints". [Jim Jagielski]
2140 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2143 *) Add tables with non-string/binary values to APR.
2146 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2149 *) Update PCRE to version 3.2. [Ryan Bloom]
2151 *) Change the way buckets' destroy functions are called so that
2152 they can be more directly used when changing the type of a
2153 bucket in place. [Tony Finch]
2155 *) Add generic support for reference-counting the resources used by
2156 buckets, and alter the HEAP and MMAP buckets to use it. Change
2157 the way buckets are initialised to support changing the type of
2158 buckets in place, and use it when setting aside TRANSIENT buckets.
2159 Change the implementation of TRANSIENT buckets so that it can be
2160 mostly shared with IMMORTAL buckets, which are now implemented.
2163 Changes with Apache 2.0a6
2165 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2167 *) Add a chunking filter to Apache. This brings us one step closer
2168 to removing BUFF. [Ryan Bloom]
2170 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2171 added to the stack is the last filter to be called. [Ryan Bloom]
2173 *) Apache 2.0 has been completely documented using Scandoc. The
2174 docs can be generated by running 'make docs'. [Ryan Bloom]
2176 *) Add filtered I/O to Apache. This is based on bucket brigades,
2177 Currently the buckets still use BUFF under the covers, but that
2178 should change quickly. The only currently written filter is the
2179 core filter which just calls ap_bwrite. [The Apache Group]
2181 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2182 built with thread support. [Jeff Trawick]
2184 *) Abort configuration if --with-layout was specified and there's
2185 no layout definition file. [Ken Coar]
2187 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2189 *) Add support for extension methods for the Allow response header
2190 field, and an API routine for accessing r->allowed and the
2191 list of extension methods in a unified manner. [Ken Coar]
2193 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2194 [Rob Simonson <simo@us.ibm.com>]
2196 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2197 APACHE_XLATE builds. [Jeff Trawick]
2199 *) A configuration file parsing problem was fixed. When the
2200 configuration file started with an IfModule/IfDefine container,
2201 only the last statement in the container would be retained.
2204 Changes with Apache 2.0a5
2206 *) Perchild is serving pages after passing them to different child
2207 processes. There are still a lot of bugs, but this does work. I
2208 have made requests against the same installation of Apache, and had
2209 different servers use different user IDs to serve the responses.
2210 This change moves to using socketpair instead of an AF_UNIX socket.
2213 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2214 It can't seem to pass between child processes yet, but I think we
2215 are closer now than before. This moves us back to using Unix
2216 Domain Sockets. [Ryan Bloom]
2218 *) libapr functions and types renamed with apr_ prefix.
2219 #include "apr_compat.h" for 1.3.x backwards compat
2222 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2223 return the right information on the local socket address.
2224 [Gregory Nicholls <gnicholls@level8.com>]
2226 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2227 [Gregory Nicholls <gnicholls@level8.com>]
2229 *) Add an option to not detach from the controlling terminal without
2230 going into single process mode. This allows for much easier
2231 debugging of the process startup code. [Ryan Bloom]
2233 *) ab: don't use perror() to report the failure of an APR function.
2236 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2237 scoreboard on graceful restarts.
2240 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2241 An invalid ap_proc_t was passed to ap_create_process().
2244 *) Allow modules to register filters. Those filters are still
2245 never called, but this is a step in the right direction.
2246 [Ryan Bloom and Greg Stein]
2248 *) Register the mod_cgid daemon process for cleanup so that it is
2249 killed at termination if it does not die when the parent gets
2250 SIGTERM. This change is to fix occasional problems where the
2251 process stays around. Bugs in similar logic in mod_rewrite and
2252 mod_include were also fixed. [Jeff Trawick]
2254 *) Fix a bug in the time handling. Basically, we were imploding a time
2255 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2256 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2257 uses those two fields to adjust the time value. Because of the HTTP
2258 spec, both of those values can be zero'ed out safely. This fixes
2259 the bug correctly. [Ryan Bloom]
2261 *) Fix a couple of place in the Windows code where the wrong error
2262 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2264 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2266 *) Added the APR_EOL_STR macro for platform dependent differences in
2267 logfiles and other raw text (such as all APR files). Fixes logfiles
2268 not terminated with cr/lf sequences in Win32. [William Rowe]
2270 *) Move all strings functions in APR to src/lib/apr/strings and create
2271 apr_strings.h for the prototypes. [Ryan Bloom]
2273 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2274 to repeat the syscall until we stop getting EINTR. I noticed a
2275 related problem at termination (SIGTERM) on FreeBSD when using
2276 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2277 implementation work properly with child init. Previously, ap_lock()
2278 was essentially a no-op because all children were using different
2279 locks and thus nobody ever blocked. [Jeff Trawick]
2281 *) The htdocs/ tree has been moved out of the CVS source tree into
2282 a separate area for easier development. This has NO EFFECT on
2283 end-users or Apache installations. [Ken Coar]
2285 *) Integrate the mod_dav module for WebDAV protocol handling. This
2286 adds the dav and dav_fs modules, the SDBM library, and additional
2287 XML handling utilities. [Greg Stein]
2289 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2292 *) Update the lib/expat-lite/ library (bring forward changes from
2293 the Apache 1.3 repository). [Greg Stein]
2295 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2296 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2298 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2299 machines where sendfile is detected, but nobody has written ap_sendfile.
2300 [Dave Hill <ddhill@zk3.dec.com>]
2302 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2304 *) ab would start up more connections than needed, then quit when the
2305 desired number were finished. Also fixed a logic error involving
2306 ab keepalives. [Victor J. Orlikowski]
2308 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2309 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2310 timeouts (i.e, if a timeout was specified, the pipe reverted to
2311 a full blocking pipe). Now the behaviour is more in line with
2312 Unix non-blocking pipes.
2315 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2316 cache open file handles along with accept socket reuse enables
2317 Apache 2.0 to serve non-keepalive requests for static files at
2318 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2319 and Apache 2.0 will serve almost 1200 rps on my system).
2322 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2323 supports two config directives, mmapfile (same behavious as
2324 mod_mmap_static) and cachefile. Use the cachefile directive
2325 to cache open file handles. This directive only works on systems
2326 that have implemented the ap_sendfile API. cachefile works today
2327 on Windows NT, but has not been tested on any flavors of Unix.
2330 *) Cleanup the configuration. With the last few changes the
2331 configuration process automatically:
2332 inherits information about how to build from APR. Allowing
2333 APR to inform Apache that it should or should not use -ldl
2335 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2336 based on the threading model
2338 Apache calls APR's configure process before finishing it's
2339 configuration processing, allowing for more information flow
2344 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2345 with non-zero argument makes the socket non-blocking. BeOS and
2346 OS/2 already worked this way. [Jeff Trawick]
2348 *) ap_close() now calls ap_flush() for buffered files, so write
2349 operations work a whole lot better on buffered files.
2352 *) Fix error messages issued from MPMs which explain where to change
2353 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2356 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2357 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2358 now the way that the blocking state of a pipe is manipulated.
2359 ap_block_pipe() is gone. [Jeff Trawick]
2361 *) Correct the problem where the only local host name that the IP stack
2362 can discover are 'undotted' private names. If no fully qualified
2363 domain name can be identified, the default ServerName will be set to
2364 the machine's IP address string. A warning is always provided if the
2365 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2367 *) Repair problems with config file processing which caused segfault
2368 at init when virtual hosts were defined and which caused ServerName to
2369 be ignored when there was no valid DNS setup. [Jeff Trawick]
2371 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2373 *) Add ap_sendfile implementation for AIX
2374 [Victor J. Orlikowski]
2376 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2377 apr_network_io.h, and apr_thread_proc.h.
2378 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2380 *) Bring the allocation and pool debugging code back into a working
2381 state. This will need to be tested as so far it's only been used on
2384 *) Change configuration command setup to be properly typesafe when in
2385 maintainer mode. Note that this requires a compiler that can initialise
2386 unions. [Ben Laurie]
2388 *) Turn on buffering for config file reads. Part of this was to
2389 repair buffered I/O support in Unix and implement buffered
2390 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2392 *) Win32: Fix problem where UTC offset was not being set correctly
2393 in the access log. Problem reported on news group by Jerry Baker.
2396 *) Fix segfault when reporting this type of syntax error:
2397 "</container> without matching <container> section", where
2398 container is VirtualHost or Directory or whatever.
2401 *) Prevent the source code for CGIs from being revealed when using
2402 mod_vhost_alias and the CGI directory is under the document root
2403 and a user makes a request like http://www.example.com//cgi-bin/cgi
2404 as reported in <news:960999105.344321@ernani.logica.co.uk>
2407 *) Add support for the new Beos NetwOrking Environment (BONE)
2410 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2411 final input char is incomplete; ap_bwrite_xlate() now handles
2412 incomplete final input chars. [Jeff Trawick]
2414 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2415 that a bhalfduplex call occurs before logging or else DNS and
2416 such can delay the last packet of the response. [Dean Gaudet]
2418 *) Some syscall reduction in APR on unix -- don't seek when setting
2419 up an mmap; and don't fcntl() more than once per socket.
2422 *) When mod_cgid is started as root, the cgi daemon now switches
2423 to the configured User/Group (like other httpd processes)
2424 instead of continuing as root. [Jeff Trawick]
2426 *) The prefork MPM now uses an APR lock for the accept() mutex.
2427 It has not been getting a lock at all recently. httpd -V now
2428 displays APR's selection of the lock mechanism instead of the
2429 symbols previously respected by prefork. [Jeff Trawick]
2431 *) Change the mmap() feature test to check only for existence.
2432 The previous check required features not used by Apache.
2435 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2436 sometimes mangled. The len parm to accept() was not
2437 initialized, leading sometimes to an endless loop of failed
2438 accept() calls on OS/390 and anywhere else that failed the call
2439 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2440 instead of declaring it ourselves to fix a compilation problem
2441 on Solaris. [Jeff Trawick]
2443 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2445 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2447 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2449 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2450 initialization if ALLOC_DEBUG is defined; no known symptom
2451 otherwise. [Jeff Trawick]
2453 *) Fix typo in configure script when checking for mod_so. bash
2454 doesn't seem to have a problem but /bin/sh on Solaris does.
2455 Symptom: "./configure: test: unknown operator =="
2458 *) Rebind the Win32 NT and 9x services control into the MPM.
2459 All console, WinNT SCM and Win9x pseudo-service control code is
2460 now wrapped within the WinNT MPM.
2463 *) Make a copy of getenv("PATH") before storing for later use. Some
2464 getenv() implementations use the same storage for successive calls.
2465 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2467 *) Server Tokens work in 2.0 again. This also propogates the change
2468 to allow just the product name in the server string using
2472 Changes with Apache 2.0a4
2474 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2475 won't need to call it. [Greg Ames, Jeff Trawick]
2477 *) Move pre_config hook call to between configuration read and config
2478 tree walk. This allows all modules to implement pre_config hooks
2479 and know that they will be called at an appropriate time.
2482 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2485 *) Add pre-config hooks back to all modules.
2488 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2489 ContentDigest enabled and we can't/don't mmap the file.
2492 *) We now report the correct line number for syntax errors in config
2493 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2495 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2496 related bugs, and changed shmem/locking to use apr API. Shared-mem
2497 is currently disabled, however, because of problems with graceful
2498 restarts. [Ronald Tschalär]
2500 *) Fix corruption of IFS variable in --with-module= handling.
2501 Depending on the user's shell or customization thereof, there
2502 would be errors generating ap_config_auto.h later in the configure
2503 procedure. [Jeff Trawick]
2505 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2506 isn't used (as in 1.3), except that on Unix it is now logged via
2507 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2508 to the error log. [Greg Ames, Jeff Trawick]
2510 *) Add '-D' argument processing for run time configuration defines.
2513 *) Organize http_main.c as independent code, such that no code or
2514 global data is exported from it. WIN32 will dynamically link it
2515 to the server core, so this will prevent mutual dependency.
2518 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2519 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2522 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2523 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2525 *) Add mod_charset_lite for configuring character set translation.
2528 *) Add '-n' option to htpasswd to make it print its user:pw record
2529 on stdout rather than having to frob a text file. [Ken Coar]
2531 *) Fix saferead. Basically, we flush the output buffer if a read on the
2535 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2536 a conversion is single-byte only. [Jeff Trawick]
2538 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2539 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2542 *) Fix some minor errors where pid was being manipulated as an int
2543 instead of the portable pid_t. [Roy Fielding]
2545 *) Fix some error log prints that were printing the pointer to a
2546 structure rather than the pid within the structure.
2547 [Jeff Trawick, Roy Fielding]
2549 *) ab: Fix a command-line processing bug; track bad headers in
2550 err_response; support reading headers up to 2K.
2551 [Ask Bjoern Hansen <ask@valueclick.com>]
2553 *) Fix ap_resolve_env() so that it handles new function added in a prior
2554 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2555 config file.") as well as the constructs used by mod_rewrite.
2556 [Paul Reder <rederpj@raleigh.ibm.com>]
2558 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2560 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2561 APR to perform translation, instead of accessing the hard-coded tables
2562 in 1.3's ebcdic.c. [Jeff Trawick]
2564 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2567 *) Add the ability to hook into the config file reading phase. Basically
2568 if a directive is specified EXEC_ON_READ, then when that directive is
2569 read from the config file, the assocaited function is executed. This
2570 should only be used for those directives that must muck with HOW the
2571 server INTERPRETS the config. This should not be used for directives
2572 that re-order or replace items in the config tree. Those changes should
2573 be made in the pre-config step.
2576 *) Add mod_example to the build system.
2579 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2580 byte character sets. [Jeff Trawick]
2582 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2583 Kraemer and Oliver Reh originally according to the change log).
2586 *) Fix a couple of problems in RFC1413 support (controlled by the
2587 IdentityCheck directive). Apache did not build the request string
2588 properly and more importantly Apache would loop forever if the
2589 would-be ident server dropped the connection before sending a
2590 properly terminated response. [Jeff Trawick]
2592 *) apxs works in 2.0.
2595 *) Reliable piped logs work in 2.0.
2598 *) Introduce a hash table implementation into APR to be used for
2599 replacing tables and other random data structures in Apache.
2602 *) Add some more error reporting to htpasswd in the case of problems
2603 generating or accessing the temporary file. Also, pass in a
2604 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2605 is defined). [Ken Coar]
2607 *) Configure creates config.nice now containing your configure
2608 options. Syntax: ./config.nice [--more-options]
2611 *) Fix various return code problems in APR on Win32. For most of
2612 these, APR was returning APR_EEXIST instead of GetLastError()/
2613 WSAGetLastError(). [Jeff Trawick]
2615 *) Make piped logs work again in version 2.0
2618 *) Add VPATH support to UNIX build system of Apache and APR.
2621 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2625 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2626 Patch submitted to author.
2629 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2630 /sbin in PATH on FreeBSD (all submitted to rse previously)
2633 *) Fix building Pthread-based MPMs on OpenBSD
2634 [Sascha Schumann] PR#26
2636 *) Fix ap_readdir() problem on systems where d_name[] field in
2637 struct dirent is declared with only one byte. (This problem only
2638 affected multithreaded builds.) This caused a segfault during
2639 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2640 least). [Jeff Trawick]
2642 *) Fix some make-portability problems on at least Tru64, Irix
2644 [Sascha Schumann] PR#18, PR#39
2646 *) Add ap_sigwait() to support old-style sigwait() on systems
2647 like OS/390 and UnixWare.
2650 *) Add POSIX-thread flags for more platforms.
2653 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2654 (on Unix, at least) to handle resolver errors. Fix a bug in
2655 the definition of APR_ENOMEM so that ap_strerror() can spit
2656 out the correct error message for it.
2659 Changes with Apache 2.0a3
2661 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2664 *) API: *HOOK* macros now have an AP_ prefix
2667 *) Win32: Eliminate redundant calls to initialize winsock.
2668 [Tim Costello <timcostello@ozemail.com.au>]
2670 *) Fix bugs initializing ungetchar for pipes.
2671 [Chia-liang Kao <clkao@CirX.ORG>]
2673 *) The ab program in the src/support directory is now portable using
2677 *) Support directory is being compiled when the server is built
2680 *) The configure option --with-program-name has been added to allow
2681 developers to rename the executable at configure time. This also
2682 changes the name of the config files to match the executable's name.
2685 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2686 containing version numbers. [Martin Pool]
2688 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2689 Unix; access_log and error_log now created with these perms; non-
2690 Unix is unaffected [Jeff Trawick]
2692 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2693 Replaced more magic numbers with MD5_DIGESTSIZE.
2694 [William Rowe, Roy Fielding]
2696 *) Win32: Get mod_auth_digest compiling and added to the Windows
2697 build environment. Not tested and I'd be suprised if it
2698 actually works. [Bill Stoddard]
2700 *) Revamp the Win32 make environment. Makefiles have been removed and
2701 Apache.dsw created to bring together all the pieces. Create new file
2702 os/win32/BaseAddr.ref to define module base addresses (to prevent
2703 dll relocation at start-up).
2704 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2706 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2707 of the \015, \012, and \015\012 constants with macros.
2708 [Greg Ames <gregames@us.ibm.com>]
2710 *) Add ap_xlate_open() et al for translation of text between different
2711 character sets. The initial implementation requires iconv().
2714 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2715 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2717 *) CGI output is being timed out now.
2720 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2721 is used by the new apr file. There is no reason to create a new file
2722 with the same lifetime as the original file.
2725 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2726 module base addresses. This will help shooting seg faults
2727 in the field. [William Rowe <wrowe@lnd.com>]
2729 *) Update Apache on Windows documentation. Add new document
2730 describing how to compile Apache on Windows.
2731 [William Rowe <wrowe@lnd.com>]
2733 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2734 microseconds instead of seconds. Some storage leaks and other
2735 minor bugs in related code were fixed. [Jeff Trawick]
2737 *) Win32: First cut at getting mod_isapi working under 2.0
2738 [William Rowe <wrowe@lnd.com>]
2740 *) First stab at getting mod_auth_digest working under 2.0
2741 quick change summary:
2742 - moved the random byte generation (ap_generate_random_bytes) into APR
2743 - now uses ap_time_t
2744 - compiles and runs on linux
2746 [Brian Martin <bmartin@penguincomputing.com>]
2748 *) Win32: Move the space stripping of physical service names
2749 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2750 unresolved symbol. Add dependency checking to the
2751 CreateService call to ensure TCPIP and AFP (winsock) is started
2753 [William Rowe <wrowe@lnd.com>]
2755 *) Win32: Add code to perform latebinding on functions that may
2756 not exist on all levels of Windows where Apache runs. This
2757 is needed to allow Apache to start-up on Win95/98. All calls
2758 to non portable functions should be protected with
2759 ap_oslevel checks to prevent runtime segfaults.
2760 [William Rowe <wrowe@lnd.com>]
2762 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2764 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2766 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2767 This addresses PR 1623. Still need to address timing out runaway
2768 CGI scripts. [Bill Stoddard]
2770 *) Win32: Make ap_stat Windows 95/98 friendly
2771 [William Rowe <wrowe@lnd.com>]
2773 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2774 always fail. Need to initialise the dwOSVersionInfoSize member of the
2775 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2778 The patch also enhances ap_get_oslevel (and the associated enum) to
2779 handle selected service packs for NT4, and adds recognition for
2780 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2781 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2782 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2784 *) Get mod_rewrite building and running, and mod_status building for Win NT
2785 [Allan Edwards <ake@raleigh.ibm.com>]
2787 *) Patch to port mod_auth_db to the 2.0 api and also to support
2788 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2789 2.7.7. It should work with version 1 as well but I haven't tested it.
2790 [Brian Martin <bmartin@penguincomputing.com>]
2792 *) Get APR DSO code working under Windows. Includes cross platform
2794 [Tim.Costello@BTFinancialgroup.com]
2796 *) Fix some of the Windows APR time functions.
2799 *) FAQ changes related to tidying up historical documents on the web site.
2800 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2802 *) Move Windows DSO code into APR.
2805 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2806 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2807 at build time. At this point, the server will not compile on Windows because
2808 of the recent DSO commits. Fixing those next.
2809 [Bill Rowe & Bill Stoddard]
2811 *) Added error checking for file I/O APR routines.
2812 [Jon Travis <jtravis@covalent.net>]
2814 *) APR: Don't use the values of resolver error codes for the
2815 corresponding APR error codes. On Unix and Win32, return the
2816 proper APR error code after a resolver error. [Jeff Trawick]
2818 Changes with Apache 2.0a2
2820 *) Renamed the executable back to httpd on all platforms other
2824 *) Allow BeOS to survive restarts, log properly and a few
2825 small things it had problems with due to the way it setup
2826 users and groups. [David Reid]
2828 *) Get mod_rewrite working with APR locks
2829 [Paul Reder <rederpj@raleigh.ibm.com>]
2831 *) Actually remove the sempahore when the lock cleanup routine
2832 is called on BeOS. [David Reid]
2834 *) Clear hook registrations between reads of the config file.
2835 When DSOs are unloaded and re-loaded the old hook pointers may
2836 no longer be valid. This fix eliminates potential segfaults.
2837 [Allan Edwards <ake@raleigh.ibm.com>]
2839 *) Fix a problem with Sigfunc not being defined or bypassed
2840 if sigaction() wasn't found. [Jim Jagielski]
2842 *) Fix the locking mechanism on BSD variants. They now use fcntl
2843 locks. This allows the server to start and serve pages.
2846 *) First cut at getting the Win32 installer to work
2847 [William Rowe <wrowe@lnd.com>]
2849 *) Get htpasswd compiling under Windows
2850 [William Rowe <wrowe@lnd.com>]
2852 *) Change the log message for a bind() failure to show the
2853 interface and port number. [Jeff Trawick]
2855 *) Import the documentation from 1.3.12 and bring parts of it
2856 up-to-date with respect to the changes that have occurred
2860 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2861 now logged correctly on BeOS.
2864 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2865 Makefile.win includes the same user interface as the old
2867 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2869 *) Win32 exec now uses COMSPEC environment string for command
2870 shell path resolution.
2871 [William Rowe <wrowe@lnd.com>] PR#3715
2873 *) Win32: ap_connect() was not returning correct error condition
2875 [Allen Prescott <allen@clanprescott.com>]
2877 *) Win32: ap_open() was broken on Win9x because an NT-specific
2878 flag was passed to CreateFile. ap_puts() added an unnecessary
2880 [Jeff Trawick <trawick@us.ibm.com>]
2882 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2883 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2884 confusing ee/et name and made all extensions language/dialect
2885 rather than country reflecting. Changed example files to
2886 explicit reflect the ISO charset and added a few common
2887 ones to the example config [dirkx]
2889 *) Extend external module capability. To use this, you call
2890 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2893 *) Backported the various "default charset" fixes from 1.3.12,
2894 including the AddDefaultCharset directive. [Jim Jagielski]
2896 *) Added the capability to do ${ENVVAR} constructs in the
2897 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2898 it does this on a line by line basis; i.e. if the envvar
2899 expands to something with spaces you have to protect it
2900 by adding quotes around it (Unless of course you expect it
2901 to contains more than one argument. Alternatively you
2902 can compile it on a per token basis; which is what people
2903 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2904 hampers fancier hacks.
2905 [Dirk-Willem van Gulik]
2907 *) Changed the 'ErrorDocument' syntax in that it NO longer
2908 supports the asymetric
2910 ErrorDocument 301 "Some message
2912 Note the opening " quote, without a closing quote. It now
2913 has either the following syntaxes
2915 ErrorDocument XXX /local/uri
2916 ErrorDocument XXX http://valid/url
2917 ErrorDocument XXX "Some Message"
2919 The recognition heuristic is: if it has a space it
2920 is a message. If it has no spaces and starts with a /
2921 or is a valid URL then treat it that way. Otherwise it
2922 is assumed to be a message.
2924 This breaks backward compatibility but makes live a hell
2925 of a lot easier for GUI's and config file parsers.
2926 [Dirk-Willem van Gulik]
2928 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2929 syntax into a 'on' or 'off' syntax. As it currently is the
2930 only non nesting token which uses NO_ARGS and thus is an
2931 absolute pain for any config interface automation. This
2932 breaks backward compatibility. [Dirk-Willem van Gulik]
2934 *) Add ability to add external modules to the build process. This is
2935 done with --with-module=/path/to/module. Modules can only be added
2936 as static modules at this point.
2939 Changes with Apache 2.0a1
2941 *) Fix FreeBSD 3.3 core dump.
2942 Basically, ap_initialize() needs to get called before
2943 create_process(), since create_process() passes op_on structure
2944 to semop() to get a lock, but op_on isn't initialized until
2945 ap_initialize() calls setup_lock(). Here is a slight
2946 rearrangement to main() which calls ap_initialize() earlier...
2947 [Jeff Trawick <trawick@us.ibm.com>]
2949 *) Enable Apache to use sendfile/TransmitFile API
2950 [Bill Stoddard, David Reid, Paul Reder]
2952 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2956 *) Make file I/O and network I/O writev/sendv APIs consistent.
2957 Eliminate use of ap_iovec_t and use Posix struct iovec.
2958 Use seperate variable on ap_writev to set the number of iovecs
2959 passed in and number of bytes written.
2962 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2963 with ap_create_file_iol(). ap_create_file_iol() requires that
2964 the file be opened prior to the call using ap_open().
2967 *) Port mod_include and mod_cgi to 2.0
2968 [Paul Reder, Bill Stoddard]
2970 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2971 bytes_read/bytes_written is always valid (never -1). Plus
2972 some fixes to buff.c to correct problems introduced by the
2973 errno => ap_status_t changes a while back. Plus a fix to
2974 chunked encoding introduced right at the beginning of 2.0.
2977 *) Revamped UNIX build system to use autoconf and libtool.
2978 [Manoj Kasichainula, Sascha Schumann]
2980 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2982 *) More rigorous checking of Host: headers to fix security problems
2983 with mass name-based virtual hosting (whether using mod_rewrite
2984 or mod_vhost_alias).
2985 [Ben Hyde, Tony Finch]
2987 *) Add back support for UseCanonicalName in <Directory> containers.
2988 [Manoj Kasichainula]
2990 *) Added APLOG_STARTUP log type. This allows us to write an error
2991 message without any of the date and time information. As a part
2992 of this change, I also removed all of the calls to fprintf(stderr
2993 and replaced them with calls to ap_log_error using APLOG_STARTUP
2994 writing to stderr is no longer portable, because we don't direct
2995 stderr to the error log on all platforms.
2998 *) Convert error logging functions to take errno as an argument.
2999 This makes our error logs more portable, because some Windows API's
3000 don't set errno. This change allows us to still output a valid
3001 message on all of our platforms.
3004 *) mod_mime_magic runs in 2.0-dev now.
3005 [Paul Reder <rederpj@raleigh.ibm.com>]
3007 *) sendfile has been added to APR.
3008 [John Zedlewski <zedlwski@Princeton.EDU>]
3010 *) buff.c has been converted to no longer use errno.
3011 [Manoj Kasichainula]
3013 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
3014 interface adaption to APR functions did it. [Martin Kraemer]
3016 *) Support DSOs properly on 32-bit HP-UX 11.0
3017 [Dilip Khandekar <dilip@cup.hp.com>]
3019 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
3020 [Ralf S. Engelschall]
3022 *) Cleaned APR build environment integration and bootstrap APR
3023 automatically for developers from src/Configure.
3024 [Ralf S. Engelschall]
3026 *) Fixed building of src/support/htpasswd.c
3027 [Ralf S. Engelschall]
3029 *) When generating the Location: header, mod_speling forgot
3030 to escape the spelling-fixed uri. (Forw-Port from 1.3)
3033 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
3035 *) Change all pools to APR contexts. This is the first step to
3036 incorporating APR into Apache. [Ryan Bloom]
3038 *) Move "handler not found" warning message to below the check
3039 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
3040 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
3042 *) Support line-continuation feature in config.option file and
3043 allow the loading of multiple option sections at once via
3044 ``--with-option=<section1>,<section2>,...''
3045 [Ralf S. Engelschall]
3047 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
3049 Changes with Apache MPM
3051 *) Use asynchronous AcceptEx() and a completion port to accept and
3052 dispatch connections to threads in Windows NT/2000.
3055 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
3058 *) Implement the APACI --with-option facility
3059 (per default used the config.option file).
3060 [Ralf S. Engelschall]
3062 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
3064 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
3065 Replace pre_connection module call with a register_hook call and
3066 implement pre_connection as a hook. The intent is that these hooks will
3067 be extended to allow Apache to be multi-protocol, and also to allow the
3068 calling order to be specified on a per-hook/per-module basis.
3071 *) Implement mpm_* methods as "modules". Each method gets its own
3072 subdir in src/modules (eg: src/modules/prefork). Selection
3073 of method uses Rule MPM_METHOD. [Jim Jagielski]
3075 *) Port the hybrid server from the apache-apr repository as
3076 mpm_mpmt_pthread. [Manoj Kasichainula]
3078 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3079 amongst the unix MPMs.
3081 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3082 signal handling for the new world order. [Dean Gaudet]
3084 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3085 of alloc.c for now. [Dean Gaudet]
3087 *) Handle partial large writes correctly. [Ben Laurie]
3089 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3090 based on IP/port. [Ben Laurie]
3092 *) Port a bunch of modules to the new module structure.
3093 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3095 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3097 *) Basic restructuring to introduce the MPM concept; includes various
3098 changes to the module API... better described by
3099 docs/initial_blurb.txt. [Dean Gaudet]
3101 Changes with Apache pthreads
3103 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3104 buff operations (generally over a network).
3105 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3107 *) Created http_accept abstraction. Added 4 new functions (not exported):
3108 init_accept(), begin_accepting_requests(), get_request(),
3109 stop_accepting_requests() [Bill Stoddard]
3111 *) Fix to ap_rprintf call that allows mod_info to work properly.
3112 [James Morris <jmorris@intercode.com.au>]
3114 *) user and ap_auth_type fields were moved from connection_rec to
3115 request_rec. [Ryan Bloom]
3117 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3118 needed in a threaded server.
3120 *) Initial pthread implementation from from Dean's apache-nspr code.
3121 [Bill Stoddard, Ryan Bloom]
3124 Changes with Apache 1.3.9
3126 *) Remove bogus error message when a redirect doesn't set Location.
3127 Instead, use an empty string to avoid coredump if the error message
3128 was supposed to include a location. [Roy Fielding]
3130 *) Don't allow configure to include mod_auth_digest unless it is
3131 explicitly requested, even if the user asked for all modules.
3134 *) Translate module names to dll names for OS/2 so that they are no more
3135 than 8 characters long and have an extension of "dll" instead of "so".
3138 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3139 Fix test-compile check to check for randbyte instead of trand32.
3140 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3141 and tweak to make Amaya happier. [Ronald Tschalär]
3143 *) Ensure that the installed expat include files are world readable,
3144 just like the other header files. [Martin Kraemer]
3146 *) Fixed generated AddModule adjustments in APACI's `configure' script
3147 in order to allow (new) modules like mod_vhost_alias to be handled
3148 correctly (which was touched by the adjustments for mod_alias).
3149 [Ralf S. Engelschall]
3151 *) For binary builds, add -R flag to apachectl to work around the lack of
3152 an absolute path to the ./libexec directory where the libhttp.ep file
3153 is needed for SHARED_CORE architectures. [Randy Terbush]
3155 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3156 problem observed by some Win95/98 users where they get CGI script
3157 output sent to the console. [Bill Stoddard]
3159 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3160 routines are now called ap_base64* and are 'plain' (i.e., no
3161 pool access or anything clever). Inside util.c the routines acting
3162 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3163 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3164 now but deprecated. [dirkx]
3166 *) Clean up the base64 and SHA1 additions and make sure they are
3167 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3168 files. [Roy Fielding]
3170 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3171 checking. Allow compiling on VS 6.0. [Randy Terbush]
3173 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3175 *) Use TestCompile to search for the truerand library (rather than blindly
3176 assuming its existence). If it is not found, complain (but do not
3177 exit - yet). [Martin Kraemer]
3179 *) We forgot to add the new exported function names to
3180 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3182 *) Add description of -T command-line option to usage().
3183 [Ralf S. Engelschall]
3185 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3186 searched only AFTER libap has been searched, because libap needs
3187 some symbols from libos. [Martin Kraemer]
3189 *) Fix conflict with original mod_digest related to the symbol of the
3190 module dispatch list (which has to be unique for DSO and follow the
3191 usual conventions for the installation procedure).
3192 [Ralf S. Engelschall]
3194 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3195 for other platforms as well. [Martin Kraemer]
3197 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3198 types by AP_LONG and replace reference to renamed variable 'ubuf'
3199 by 'buffer'. [Martin Kraemer]
3201 Changes with Apache 1.3.8 [not released]
3203 *) Flush the output buffer immediately after sending an error or redirect
3204 response, since the result may be needed by the client to abort a
3205 long data transfer or restart a series of pipelined requests.
3206 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3208 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3209 [Ian Turner <iant@sequent.com>] PR#4735
3211 *) Local struct mmap in http_core.c conflicted with system structure
3212 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3214 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3215 [Ronald Tschalär <ronald@innovation.ch>]
3217 *) Fix a memory leak where the module counts were getting messed
3218 up across restarts. [David Harris <dharris@drh.net>]
3220 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3221 properly in mod_access.
3222 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3224 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3225 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3227 *) PORT: Support for compaq/tandem/com.
3228 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3230 *) Added SHA1 password encryption support to easy migration from
3231 Netscape servers. See support/SHA1 for more information.
3232 Caused the separation of ap_md5.c into md5, sha1 and a general
3233 ap_checkpass.c with just a validate_passwd routine. Added a
3234 couple of flags to support/htpasswd. Some reuse of the to64()
3235 function; hence renamed to ap_to64().
3236 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3238 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3239 with ASCII/EBCDIC conversions in "ident" query.
3240 [David McCreedy <McCreedy@us.ibm.com>]
3242 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3243 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3244 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3246 *) Fix SIGSEGV on some systems because the Vary fix below included
3247 a call to table_do with a variable argument list that was not
3248 NULL terminated. Replaced with better implementation. [Roy Fielding]
3250 Changes with Apache 1.3.7 [not released]
3252 *) The "Vary" response header field is now sanitised right before
3253 the header is sent back to the client. Multiple "Vary" fields
3254 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3255 "Vary: host, negotiate, host, accept-language") are reduced to
3256 single instances. This is a better solution than the force-no-vary
3257 one (which is still valid for clients that can't cope with Vary
3258 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3260 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3262 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3263 least on Linux and FreeBSD for now.
3266 *) Win32: More apache -k restart work. Restarts are now honored
3267 immediately and connections in the listen queue are -not- lost.
3268 This is made possible by the use of the WSADuplicateSocket()
3269 call. The listeners are opened in the parent, duplicated, then
3270 the duplicates are passed to the child. The original listen sockets
3271 are not closed by the parent across a restart, thus the listen queue
3273 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3275 *) Fix handling of case when a client has sent "Expect: 100-continue"
3276 and we are going to respond with an error, but get stuck waiting to
3277 discard the body in the pointless hope of preserving the connection.
3278 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3280 *) Fix 'configure' to work correctly with SysV-based versions of
3281 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3283 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3284 built-in values. Add "-e" option which works like -i but doesn't
3285 install the DSO; useful for editing httpd.conf with apxs. Fix
3286 editing code so that multiple invocations of apxs -a will not
3287 create duplicate LoadModule/AddModule entries; apxs can now be
3288 used to re- enable/disable a module. [Wilfredo Sanchez]
3290 *) Win32: Update the server to use Winsock 2. Specifically, link with
3291 ws2_32.lib rather than wsock32.lib. This gives us access to
3292 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3293 Win 95 users may need to update their TCP/IP stack to pick up
3294 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3295 [Bill Stoddard stoddard@raleigh.ibm.com]
3297 *) Win32: Redirect CGI script stderr (script debug info) into the
3298 error.log when CGI scripts fail. This makes Apache on Win32
3299 behave more like Unix.
3300 [Bill Stoddard stoddard@raleigh.ibm.com]
3302 *) Fixed `httpd' usage display: -D was missing.
3303 [Ralf S. Engelschall] PR#4614
3305 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3306 [Ralf S. Engelschall] PR#4561, PR#4562
3308 *) OS/2: Fix problem with accept lock semaphores where server would die with
3309 "OS2SEM: Error 105 getting accept lock. Exiting!"
3310 [Brian Havard] PR#4505
3312 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3313 [Randy Terbush <randy@covalent.net>]
3315 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3316 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3318 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3319 command potentially _is_ GCC. [Ralf S. Engelschall]
3321 *) Fix apxs build issues on AIX
3322 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3324 *) DocumentRoot Checking: Under previous versions, when Apache
3325 first started up, it used to do a stat of each DocumentRoot to
3326 see if it existed and was a directory. If not, then an error
3327 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3328 does not exist, you will get error messages in error_log. If
3329 the '-t' command line option is used (to check the configuration)
3330 the check of DocumentRoot IS performed. An additional command
3331 line option, '-T', has been added if you want to avoid the
3332 DocumentRoot check even when checking the configuration.
3335 *) Win32: The query switch "apache -S" didn't exit after showing the
3336 vhost settings. That was inconsistent with the other query functions.
3337 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3339 *) Win32: Changed behaviour of apache -k restart.
3340 Previously, the server would drain all connections in the stack's
3341 listen queue before honoring the restart. On a busy server, this
3342 could take hours. Now, a restart is honored almost immediately.
3343 All connections in Apache's queues are handled but connections in
3344 the stack's listen queue are discarded. Restart triggered by
3345 MaxRequestPerChild is unchanged.
3346 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3348 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3349 the accept loop. Good for a 5% performance boost. Cleaned up
3350 parent/child process management code.
3351 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3353 *) Added ceiling on file size for memory mapped files.
3354 [John Giannandrea <jg@meer.net>] PR#4122
3356 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3357 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3358 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3360 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3361 use this at least for Expat. [Ralf S. Engelschall]
3363 *) Allow .module files to specify libraries with Lib:.
3366 *) Allow SetEnvIf[NoCase] to test environment variables as well
3367 as header fields and request attributes. [Ken Coar]
3369 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3370 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3372 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3373 never accepted into any standard, and it opens up certain DoS
3374 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3376 *) TestCompile updated. We can now run programs and output the
3377 results during the Configure process. [ Jim Jagielski]
3379 *) The source is now quad (long long) aware as needed. Specifically,
3380 the Configure process determines the correct size of off_t and
3381 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3382 provides for the 'q' format qualifier (if quads are not available,
3383 'q' is silently "demoted" to long). [Jim Jagielski]
3385 *) When the username or password fed to htpasswd is too long, include the
3386 size limit in the error message. Also report illegal characters
3387 (currently only ':') in the username. Add the size restrictions
3388 to the man page. [Ken Coar]
3390 *) Fixed the configure --without-support option so it doesn't result in
3391 an infinite loop. [Marc Slemko]
3393 *) Piped error logs could cause a segfault if an error occured
3394 during configuration after a restart.
3395 [Aidan Cully <aidan@panix.com>] PR#4456
3397 *) If a "Location" field was stored in r->err_headers_out rather
3398 than r->headers_out, redirect processing wouldn't find it and
3399 the server would core dump on ap_escape_html(NULL). Check both
3400 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3401 if Location isn't set. [Doug MacEachern, Ken Coar]
3403 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3404 of the Expat 1.0.2 distribution. [Greg Stein]
3406 *) Replace regexec() calls with calls to a new API stub function
3407 ap_regexec(). This solves problems with DSO modules which use the regex
3408 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3410 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3411 environment variables can be set according to the protocol version
3412 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3414 *) Add DSO support for OpenStep (Mach 4.2) platform.
3415 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3417 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3418 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3420 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3421 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3423 *) Better DSO flags recognition on NetBSD platforms using ELF.
3424 [Todd Vierling <tv@pobox.com>] PR#4310
3426 *) Always log months in english format for %t in mod_log_config.
3427 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3429 *) Support for server-parsed and multiview-determined ReadmeName and
3430 HeaderName files in mod_autoindex. Removed the restriction on
3431 "/"s in ReadmeName and HeaderName directives since the *sub_req*

3662 a roughly 5 fold speed up. [Brian Havard]
3664 *) proxy ftp: instead of using the hardwired string "text/plain" as
3665 a fallback type for files served by the ftp proxy, use the
3666 ap_default_type() function to determine the configured type.
3667 This allows for special configurations like
3668 <Directory proxy:ftp://some.host>
3669 DefaultType gargle/blurb
3671 Additionally, add the Content-Encoding: header to FTP proxy replies
3672 when the encoding is defined (by the AddEncoding directive).
3673 Because it was missing, it was almost impossible to browse compressed
3674 files using the FTP proxy (works now perfectly in Communicator).
3675 The ftp proxy now also returns the Date: and Server: header lines (if not
3676 much else... This code is "somewhat" broken) like normal requests do.
3679 *) Be more smart in APACI's configure script when determining the UID/GID
3680 for User/Group directives and use the determined UID/GID to initialize
3681 the permissions on the proxycachedir.
3682 [Dirk-Willem van Gulik, Ralf S. Engelschall]
3684 *) Changed the forking-prior-to-cleanup in the proxy module to first

3719 *) Added PassAllEnv; makes server's entire environment available
3720 to CGIs and SSIs executed within directive's scope. [Ken Coar]
3722 *) ap_uuencode() always added two trailing '='s and encoding of
3723 8 bit characters on a machine with signed char may produced

3725 work correctly on EBCDIC platforms.
3726 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
3728 *) WIN32: Binary installer now runs the configuration DLL before
3729 the reboot prompt (which is only given if MSVCRT.DLL system

3755 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3756 for 8-bit safeness. [Dean Gaudet]
3758 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3759 because SPARCs have a small machine-specific maximum size for the Global
3760 Offset Table which is often exceeded when compiling one of the larger
3761 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3763 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

3796 *) In configure, do not append the target name to the directory path if
3797 the path already contains "apache". [Ralf S. Engelschall]
3799 *) SIGPIPE is now ignored by the server core. The request write routines
3800 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3801 correctly check for output errors and mark the connection as aborted.
3802 Replaced many direct (unchecked) calls to ap_b* routines with the
3803 analogous ap_r* calls. [Roy Fielding]
3805 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3806 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3807 Furthermore map lookups for non-existent keys are now cached as well.
3808 Additionally "txt" maps are now parsed with simple string functions
3809 instead of using ap_pregcomp(). As a side effect a bug that prevented
3810 the usage of keys containing the "," character was fixed.
3811 The changes drastically improve the performance when large rewrite maps
3813 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

3821 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3822 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3824 *) Add %V to mod_log_config, this logs the hostname according to the
3825 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3826 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3828 *) Add support for \n and \t to mod_log_config, can be used to produce
3829 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3831 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
3833 *) Added informative error messages for failed munmap() and fseek() calls

3837 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
3839 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
3840 is removed. This allows <Directory proxy:*> directives to work and
3841 prevents invalid requests from killing the process.
3842 [Brian Havard <brianh@kheldar.apana.org.au>]

3848 David N. Welton: you can now have it generate an HTML TABLE, presumably
3849 for integration into other HTML sources. David updated the ab man page
3850 as well and added some missing descriptions. Thanks!
3851 [David N. Welton <davidw@prosa.it>]

3854 characters in the range 0x80 to 0xff (for example accented characters).
3855 [Paul Sutton] PR#3890
3857 *) Added conditional logging based upon environment variables to
3858 mod_log_config. mod_log_referer and mod_log_agent
3859 are now deprecated. [Ken Coar]
3861 *) Allow apache acting as a proxy server to relay the real
3862 reason of a failure to a client rather than the "internal
3863 server error" it does currently. The general exposure mechanism
3864 can be triggered by any module by setting the "verbose-error-to"
3865 note to "*"; this allows more than just proxy errors to be exposed.
3866 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3868 *) Moved man pages for ab and apachectrl to section 8.
3869 [Wilfredo Sanchez, Roy Fielding]
3871 *) Added -S option to install.sh so that options can be passed to
3872 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3874 *) Tweak modules Makefile generated by Configure so that it handles
3875 the test case of no modules being selected. [chaz@reliant.com]
3877 *) Added a <LimitExcept method ...> sectioning directive that allows
3878 the user to assign authentication control to any HTTP method that
3879 is *not* given in the argument list; i.e., the logical negation
3880 of the <Limit> directive. This is particularly useful for controlling
3881 access on methods unknown to the Apache core, but perhaps known by
3882 some module or CGI script. [Roy Fielding, Tony Finch]
3884 *) Prevent apachectl from complaining if the PIDFILE exists but
3885 does not contain a process id, as might occur if the server is
3886 being rapidly restarted. [Wilfredo Sanchez]
3888 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3890 *) Entity tag comparisons for If-Match and If-None-Match were not being
3891 performed correctly -- weak tags might cause false positives. Also,
3892 strong comparison wasn't properly enforced in all cases.
3893 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
3895 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
3898 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3899 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3901 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3902 to util.c for parsing an HTTP header field value to extract the next
3903 list item, taking into account the possible presence of nested comments,
3904 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3905 insignificant whitespace and lowercases non-quoted tokens.
3906 [Roy Fielding] PR#2065
3908 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3909 code different from 500. This allows the proxy to, e.g., return
3910 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3912 *) Fix ordering of language variants for the case where the traditional
3913 negotiation algorithm is being used with multiple language variants
3914 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3916 *) Do not round the TCN quality calculation to 5 decimal places,
3917 unlike RFC 2296, because the calculation might need 12 decimal places
3918 to get the right result. [Roy Fielding]
3920 *) Remove unused code to disable transparent negotiation when
3921 negotiating on encoding only, as we now handle encoding too
3922 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3923 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3924 some debugging statements within mod_negotiation. [Koen Holtman]
3926 *) Fixed a rare memory corruption possibility in mod_dir if the index
3927 file is negotiable and no acceptable variant can be found.
3928 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3930 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3931 searching the Win32 registry for script interpreters.
3934 *) Win32: The compiled-in default filename for the error log is now
3935 error.log, which matches the default in the distributed httpd.conf.
3938 *) Win32: Any error messages from -i or -u command line options are now
3939 displayed on the console output rather than sent to the error log.
3940 Also the "Running Apache..." message is not output unless Apache is
3941 going to serve requests. [Paul Sutton]
3943 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3944 and use a private significator ('$apr1$') to mark passwords as
3945 being smashed with our own algorithm. Also abstract the password
3946 checking into a new ap_validate_password() routine. [Ken Coar]
3948 *) Win32: The filename validity checker now allows "COM" but refuses
3949 access to "COM1" through "COM4". This allows filenames such
3950 as "com.name" to be served. [Paul Sutton] PR#3769.
3952 *) BS2000: Adapt to the new ufork() system call interface which will
3953 make subtasking easier on the OSD/POSIX mainframe environment.
3956 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3957 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3959 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
3960 use `.db' instead of `.pag' not only for FreeBSD, but also when
3961 the NDBM library looks like Berkeley-DB based.
3962 [Ralf S. Engelschall] PR#3773
3964 *) Add ability to handle DES or MD5 authentication passwords.

3967 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
3969 *) SECURITY: Avoid some buffer overflow problems when escaping
3970 quoted strings. (This overflow was on the heap and we believe
3971 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3973 *) Let src/Configure be aware of CFLAGS options starting with plus
3974 signs as it's the case for the HP/UX compiler.
3975 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3977 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3978 and check to see if the tar we wind up with supports '-h'.
3979 [Jim Jagielski] PR#3671
3981 *) A consistent and conservative style for all shell scripts has been
3982 implemented. Basically, all shell string tests use the traditional
3983 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3984 to protect against bare null variable strings (ie: wrapping both
3985 sides with double quotes and prepending 'x'). 'x' was chosen
3986 because it's more universal and hopefully easier for old shell
3987 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3990 *) The status module now prints out both the main server generation as
3991 well as the generation of each process. Also, the vhost info is
3992 printed with '?notable'. [Jim Jagielski]
3994 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3995 and this makes its functions available to things in src/support.
3998 Changes with Apache 1.3.4
4000 *) Renamed macros status_drops_connection to ap_status_drops_connection
4001 and vestigial scan_script_header to ap_scan_script_header_err,
4002 mostly for aesthetic reasons. [Roy Fielding]
4004 *) The query switch "httpd -S" didn't exit after showing the
4005 vhost settings. That was inconsistent with the other query functions.
4008 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
4009 filename to the end of the STANDARD_MODULE_STUFF. Its
4010 presence at the beginning prevented reporting of the filename
4011 for modules compiled before 1 January 1999. [Ken Coar]
4013 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
4014 to detect and prevent access to special DOS device file names.
4015 [Paul Sutton, Ken Parzygnat]
4017 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
4018 and Makefile_win32_debug.txt (debug build) that work on Win95.
4019 Run each of the following from the src directory:
4020 nmake /f Makefile_win32.txt # compiles normal build
4021 nmake /f Makefile_win32.txt install # compiles and installs
4022 nmake /f Makefile_win32.txt clean # removes compiled junk
4023 nmake /f Makefile_win32_debug.txt # compiles debug build
4024 nmake /f Makefile_win32_debug.txt install
4025 nmake /f Makefile_win32_debug.txt clean
4028 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
4029 to build binary distributions. [Lars Eilebrecht]
4031 *) IndexOptions SuppressColumnSorting only turned off making
4032 the column headers anchors; you could still change the display
4033 order by manually adding a '?N=A' or similar query string to the
4034 URL. Now SuppressColumnSorting locks in the sort order so
4035 it can't be overridden this way. [Ken Coar]
4037 *) Added IndexOrderDefault directive to supply a default sort order
4038 for FancyIndexed directory listings. [Ken Coar] PR#1699
4040 *) Change the ap_assert macro to a variant that works on all platforms.
4041 [Richard Prinz <richard.prinz@cso.net>] PR#2575
4043 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
4044 search for an underscore on dlsym() (as it's already the case
4045 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
4047 *) Small fix for mod_env.html: The module was documented as to be _not_
4048 compiled into Apache per default, although it _IS_ compiled into
4049 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
4051 *) Instead of fixing a bug in the generation procedure for config.status (a
4052 backslash was missing) we remove the bug together with it's complete
4053 context because the special cases of the past can now no longer occur
4054 because of the recent magic for the --with-layout default.
4055 [Ralf S. Engelschall] PR#3590
4057 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
4058 making sure the src/support/ tools are _forced_ to be build last (they
4059 depend on other libraries).
4060 [Markus Theissinger <markus.theissinger@gmx.de>]
4062 *) Fix installation procedure: Now that os-inline.c is actually used (a
4063 recently fixed bug prevented this) we need to also install os-include.c
4064 in addition to os.h into the PREFIX/include/ location or building of
4065 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
4067 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4068 allow us to distinguish between a garbled DSO (or even a file which isn't
4069 an Apache module DSO at all) and a DSO which doesn't match the current
4070 Apache API. [Ralf S. Engelschall] PR#3152
4072 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4073 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4074 match case insensitive (this especially avoids nasty patterns like
4075 `[tT][eE][sS][tT]'). Second two additional internal map functions
4076 `escape' and `unescape' were added which can be used to escape/unescape
4077 to/from hex-encodings in URLs parts (this is especially useful in
4078 combination with map lookups).
4079 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4081 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4082 forgotten (because it was a macro) in the symbol renaming process.
4083 [Ralf S. Engelschall]
4085 *) Fix some inconsistencies related to the scopes of directives. The only
4086 user visible change is that the directives `UseCanonicalName' and
4087 `ContentDigest' now use the (more correct) `Options' scope instead of
4088 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4090 *) Using DSO, the Server token was being mangled. Specifically, the
4091 module's token was being added first before the Apache token. This
4092 has been fixed. [Jim Jagielski]
4094 *) Major overhaul of mod_negotiation.c, part 2.
4095 - properly handle "identity" within Accept-Encoding.
4096 - allow encoded variants in RVSA negotiation and let them appear in
4097 the Alternates field using the non-standard "encoding" tag-list.
4098 - fixed both negotiation algorithms so that an explicitly accepted
4099 encoding is preferred over no encoding if "identity" is not
4100 included within Accept-Encoding.
4101 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4102 of large substring sequences.
4103 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4106 *) Major overhaul of mod_negotiation.c, part 1.
4107 - cleanups to mod_negotiation comments and code structure
4108 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4109 support for everything in the upcoming HTTP/1.1
4110 revision (draft-ietf-http-v11-spec-rev-06.txt).
4111 - language tag matching also handles tags with more than 2
4113 - empty Accept, Accept-Language, Accept-Charset headers are
4114 processed correctly; previously an empty header would make all
4115 values acceptable instead of unacceptable.
4116 - allowed for q values in Accept-Encoding
4117 - added support for transparent content negotiation (rfc2295 and
4118 rfc2296) (though we do not implement all features in these drafts,
4119 e.g. no feature negotiation). Removed old experimental version.
4120 - implemented 'structured entity tags' for better cache correctness
4121 (structured entity tags ensure that caches which can deal with Vary
4122 will (eventually) be updated if the set of variants on the server
4124 - this involved adding a vlist_validator element to request_rec
4125 - this involved adding the ap_make_etag() function to the global API
4126 - modified guessing of charsets used by Apache negotiation algorithm
4127 to guess 'no charset' if the variant is not a text/* type
4128 - added code to sort multiviews variants into a canonical order so that
4129 negotiation results are consistent across backup/restores and mirrors
4130 - removed possibility of a type map file resolving to another type map
4131 file as its best variant
4132 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4134 *) RFC2396 allows the syntax http://host:/path (with no port number)
4135 but the proxy disallowed it (ap_proxy_canon_netloc()).
4136 [David Kristol <dmk@bell-labs.com>] PR#3530
4138 *) When modules update/modify the file name in the configfile_t structure,
4139 syntax errors will report the updated name, not the original one.
4140 [Fabien Coelho <coelho@cri.ensmp.fr>] PR#3573
4142 *) Correct some filename case assumptions from WIN32 to
4143 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4145 *) For %v log ServerName regardless of the UseCanonicalName
4146 setting (similarly for %p). [Dean Gaudet]
4148 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4149 rather late (too late for some invocations of TestCompile).
4150 This improves the make environment available to TestCompile and
4151 the *.module scripts. [Martin Kraemer]
4153 *) The hashbang emulation code in ap_execve.c would interpret
4154 #!/hashbang/scripts correctly, but failed to fall back to a
4155 standard shell for scripts which did NOT start with #!
4156 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4158 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4161 *) Update APXS manual page: some -q option arguments were missing
4162 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4164 *) Cleanup the command line options: `-?' was documented to show
4165 the usage list but does it with an error because `?' is not a valid
4166 command. OTOH a lot of users expect `-h' to print such a usage list and
4167 instead are annoyed for ages by our huge unreadable list of directives.
4168 So we now changed the command line options this way:
4170 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4171 very similar to the popular linker option.
4173 Intent: while -l gives the small list of modules, -L now gives the
4174 large list of directives implemented by these modules. This is also
4175 consistent with -v (short version info) and -V (large version info).
4177 Intent: it's now the expected option ;-)
4178 The manual page was adjusted accordingly.
4179 [Ralf S. Engelschall] PR#2714
4181 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4182 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4184 *) Removed recently introduced bugs and disfigurements in APACI:
4185 o fixed argument line processing: using $args was broken: It was not
4186 initialized and using args="$args $apc_option" and even args="$args
4187 \"$apc_option\"" fails in the second processing round for any arguments
4188 containing whitespaces. The only correct way is to use the construct
4189 "$@" (but not possible here) or iterate _both_ times over the implicit
4190 argument line (no argument to for-loop) which is what we now use.
4191 o make --with-layout=Apache the default without creating
4192 redundancy (copying the --with-layout block in the argument parsing
4193 loop). We achieve this by using the "$@" construct together with the
4194 `set' command to prepend --with-layout=Apache to the command line in
4195 case --with-layout is not used.
4196 o fixed auto-suffix handling now that config.layout exists.
4197 Paths which are auto-suffixed are marked with a trailing plus sign in
4198 config.layout and every path now can be marked this way (not only the
4199 four paths for which we do it currently). Additionally the suffix is
4200 no longer a static one. Instead it's now `/<target>' where <target> is
4201 the argument of the --target option or per default `httpd'.
4202 o allow also tabs (and only spaces) where we match whitespaces
4203 o various fixes and cleanups related to used shell coding style
4204 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4205 o trimmed output of --help to fit into 80 columns
4206 [Ralf S. Engelschall]
4208 *) Added two new core API functions, ap_single_module_configure() and
4209 ap_single_module_init(), which are now used by mod_so to configure a module
4210 after loading. [Ralf S. Engelschall]
4212 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4213 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4214 of ap_config.h to allow serialized accept for multiport listens.
4215 [Roy Fielding, Curt Sampson] PR#3120
4217 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4218 of ap_config.h that would skip several defines if DEFAULT_GROUP
4219 was overridden. [Roy Fielding]
4221 *) PORT: The I86 version of DGUX has support for strncasecmp and
4222 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4224 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4225 defined before it might be used. [Victor Khimenko]
4227 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4228 [Tom Serkowski <tks@bsdi.com>] PR#3453
4230 *) Make generation of src/Configuration.apaci more robust: It failed to
4231 differenciate between modules when one module name was a postfix of
4232 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4233 just XXX (think about totally non-standard names like "apache_ssl", too).
4234 [Ralf S. Engelschall] PR#3380
4236 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4237 since 1.3b7) and make whitespace handling more robust (it failed horrible
4238 when whitespaces were present in the arguments of -D options).
4239 [Ralf S. Engelschall] PR#3240
4241 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4242 creates an external package shadow tree in DIR before the local build
4243 shadow tree is generated under DIR. This way one can have the extracted
4244 Apache distribution tree read-only on NFS or CDROM and still build Apache
4245 from these sources. An automatically triggered VPATH-like mechanism is
4246 provided through the TOP variable, too.
4247 [Ralf S. Engelschall, Wilfredo Sanchez <wsanchez@apple.com>]
4249 *) Fix negotiation so that a Vary response header is correctly
4250 generated when, for a particular dimension, variants only vary
4251 in having or not having a value for that dimension. [Paul Sutton]
4253 *) Fix negotiation so that we prefer an encoded variant over an
4254 unencoded variant if the user-agent explicitly says it can
4255 accept that encoding. Previously we always preferred the unencoded
4257 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
4259 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
4260 and the usage page was inconsistent with the functionality and manpage.
4261 [Ralf S. Engelschall]
4263 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4264 They can occur multiple times and their arguments (`xxx') are passed AS
4265 IS to the compiler/linker command. [Ralf S. Engelschall]
4267 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4268 procedure of mod_rewrite: very long keys were truncated.
4269 [Ralf S. Engelschall]
4271 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4272 identifier, currently "Apache" and "GNU" are pre-defined in the file
4273 config.layout. Custom layouts are possible by using FILE:ID as the
4274 argument where the layout ID is taken from FILE.
4276 The config.layout file consists of <Layout ID>..</Layout> sections
4277 where inside those sections "path_variable: path_value" pairs can be
4278 specified. These lines are converted to path_variable='path_value'.
4280 *) Add a DefaultLanguage directive so that files missing a language
4281 extension (e.g., .fr, .de) can be labelled as being some other
4282 default language. DefaultLanguage can appear in <Directory> and
4283 <Files> containers as well as .htaccess files. [Paul Sutton]
4286 *) Fix TARGET configuration when configuring and installing using
4287 APACI configure. TARGET now defines the basename of the configuration
4288 file, startup script, manual page, etc. log_error_core() now reports
4289 the server binary name given by argv[0]. TARGET can now also be defined
4290 with --target=TARGET parameter passed to APACI configure.
4291 [Ralf Engelschall, Randy Terbush]
4293 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
4294 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]
4296 *) ap_md5_binary() was using sprintf() rather than a table lookup
4297 to convert binary bytes to hex digits.
4298 [Ronald Tschalär <ronald@innovation.ch>] PR#3409
4300 *) Fix SEGV in TCN negotiation if no variants are acceptable.

4303 *) API: ap_exists_config_define() function is now "public" [Doug MacEachern]
4305 *) Fix documentation of `Action' directive: It can activate a CGI script
4306 when either a handler or a MIME content type is triggered by the request.
4307 [Andrew Pimlott <pimlott@math.harvard.edu>] PR#3340

4313 notice to the error log. It is not possible to send a 401 response
4314 and a redirect at the same time. [Lars Eilebrecht]
4316 *) Fallback to native compilers for IRIX-32 platform. It seems that
4317 a gcc 2.8.1 compiled apache is logging client addresses with all
4318 bits set (255.255.255.255). This is the second such problem caused
4319 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4322 *) Updated mime.types to reflect current Internet media types
4323 and include a URL to the registry.

4330 used to set the document root directory (DOC_ROOT) and the suexec
4331 logfile (LOG_EXEC), respectively. Additionally the --layout option
4332 was changed to show more information about the suEXEC setup.

4397 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4398 in the Configuration[.apaci] file. Two special and important variants are
4399 supported for the option argument: first BEGIN:foo which permutes module
4400 mod_foo with the begin of the module list, i.e. it `moves' the module to
4401 the begin of the list (gives it lowest priority). And second foo:END
4402 which permutes mod_foo with the end of the module list, i.e. it `moves'
4403 the module to the end of the list (gives it highest priority).

4430 *) Fix Berkeley-DB/2.x support in mod_auth_db: The data structures were not
4431 initialized correctly and the db_open() call used an invalid mode
4432 parameter. [Ron Klatchko <ron@ckm.ucsf.edu>] PR#3171
4434 *) PORT: DSO support for UnixWare 7
4435 [Ralf S. Engelschall, Ron Record <rr@sco.com>]
4437 *) Merge the contents of the {srm,access}.conf-dist* files into the
4438 httpd.conf-dist* files. The srm and access files now contain
4439 only comments, and httpd.conf has all the combined contents in
4440 a rational order. [Ken Coar]
4442 *) PORT: DSO/ELF support for FreeBSD 3.0.
4443 [Ralf S. Engelschall, Dirk Froemberg <ibex@physik.TU-Berlin.DE>]
4445 *) Add a "default-handler" handler that calls the default_hander()
4446 function which is normally called for static content. This allows
4447 you to override a specific handler. [Marc Slemko]
4449 *) Further simplify checking for absolute paths by replacing an
4450 hard-coded syntax check with a call to a routine we already created to
4451 do this. [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074
4453 *) Log an error if we encounter a malformed "require" directive
4454 in mod_auth if we know that we know that no other module can
4455 deal with it. [Marc Slemko]
4457 *) Remove ap_private_extern method of hiding conflicting symbols
4458 on the NEXT platform because it is not correct for all versions,
4459 and the versions for which it is correct are unknown.
4460 [Wilfredo Sanchez <wsanchez@apple.com>]
4462 *) Fix inheritance of IndexOptions NameWidth and remove unintended
4463 restriction on +NameWidth, +IconHeight, and +IconWidth. [Ken Coar]

4466 is encountered in an .htaccess file somewhere down the tree.
4469 *) Minor performance improvement to ap_escape_html(). [Roy Fielding]
4471 *) Fixed a segmentation violation in mod_proxy when a response is
4472 non-cachable. [Roy Fielding, traced by Doug Bloebaum]. PR#2950, 3056
4474 Changes with Apache 1.3.3
4476 *) Added a complete implementation of the Expect header field as
4477 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
4478 response when we already know the final status, which is mighty
4479 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4481 *) Remove extra trailing whitespace from the getline results as part
4482 of the protocol processing, which is extra nice because it works
4483 between continuation lines, is almost no cost in the normal case
4484 of no extra whitespace, and saves memory. [Roy Fielding]
4486 *) Added new HTTP status codes and default response bodies from the
4487 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
4488 HTTP Extension Framework (510) specifications. Did not add the
4489 WebDAV 424 and 425 codes because they are bogus. We don't use any
4490 of these codes yet, but they are now available to 3rd-party modules.
4493 *) Fix a possible race condition between timed-out requests and the
4494 ap_bhalfduplex select that might result in an infinite loop on
4495 platforms that do not validate the descriptor. [Roy Fielding]
4497 *) WIN32: Add "-k shutdown" and "-k restart" options to signal a
4498 running Apache server [Paul Sutton]
4500 *) Fix mod_autoindex bug where directories got a size of "0k" instead
4501 of "-". [Martin Plechsmid <plechsmi@karlin.mff.cuni.cz>, Marc Slemko]

4510 *) PORT: Fix sys/resource.h handling for SCO 3.x platform.
4511 [M. Laak <maert@proinv.ee>] PR#3108
4513 *) Fallback from sysconf-based to plain HZ-based `ticks per second'
4514 calculation in mod_status for all systems which don't have POSIX
4515 sysconf() (like UTS 2.1) and not only for the NEXT platform.
4516 [Dave Dykstra <dwd@bell-labs.com>] PR#3055
4518 *) Fix `require ...' directive parsing in mod_auth, mod_auth_dbm and
4519 mod_auth_db by using ap_getword_white() (which uses ap_isspace())

4521 but not tabs). [James Morris <jmorris@intercode.com.au>,

4548 working directory to fill in some blanks. [Ken Parzygnat
4549 <kparz@raleigh.ibm.com>] PR#3001
4551 *) Correct invalid assumption by ap_sub_req_lookup_file() that all

4553 [Ken Parzygnat <kparz@raleigh.ibm.com>] PR#2976, 3074

4556 so that ErrorDocument 300 processors can reformat the list
4557 if desired. [Ken Coar] PR#2859
4559 *) Add +/- incremental prefixes to IndexOptions keywords, and
4560 enable merging of multiple IndexOptions directives. [Ken Coar]
4562 *) PORT: Allow GuessOS to recognize Unixware 7.0.1 [Steve Cameron
4563 <steve.cameron@compaq.com>]
4565 *) Reconstructed the loop through multiple htaccess file names so
4566 that missing files are not confused with unreadable files.
4569 *) The ap_pfopen and ap_pfdopen routines were failing to protect the
4570 errno on an error, which leads to one error being mistaken for
4571 another when reading non-existent .htaccess files.
4574 *) OS/2: The new header tests get things right, need to update
4575 ap_config.h. [Brian Havard]
4577 *) The Perl %ENV hash will now be setup by default when using the
4578 mod_include `perl' command [Doug MacEachern]

4589 *) Avoid possible line overflow in Configure: Use an awkfile to
4590 handle the creation of modules.c [Jim Jagielski]
4592 Changes with Apache 1.3.2
4594 *) Fix bug in ap_remove_module(), which caused problems for dso's
4595 who were the top_module. [Doug MacEachern]
4597 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
4598 mod_auth_db to both be friendly to users who wants to use this version
4599 and to avoid problems under platforms where only version 2.x is present.
4600 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
4602 *) When using ap_log_rerror(), make the error message available to the
4603 *ERROR_NOTES envariables by default. [Ken Coar]
4605 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
4606 You now must define a BS2000Account name for the server User.
4607 This has fewer security implications than the old approach.
4610 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4611 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4612 platform to make the braindead HPUX linker happy. Notice, for the module
4613 DSOs we don't have to use this, because these are loaded manually (and
4614 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968
4616 *) Remove 64 thread limit on Win32.
4617 [Bill Stoddard <stoddard@raleigh.ibm.com>]
4619 *) Remove redundant substitutions in top-level Makefile.tmpl.
4620 [Ralf S. Engelschall]
4622 *) Fix APACI's `Group' configuration adjustment - especially for Linux
4623 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
4625 *) Make PrintPath work generically instead of having one version
4626 strictly for OS/2. [Jim Jagielski, Brian Havard]
4628 *) Fix the recently introduced C header file checking: We now use the C
4629 pre-processor pass only (and no longer the complete compiler pass) to
4630 determine whether a C header file exists or not. Because only this way
4631 we're safe against inter-header dependencies (which caused horrible
4632 portability problems). The only drawback is that we now have a CPP
4633 configuration variable which has to be determined first (we do a similar
4634 approach as GNU Autoconf does here). When all fails the user still has
4635 the possibility to override it manually via APACI or src/Configuration.
4636 As a fallback for the header check itself we can directly check the
4637 existance of the file under /usr/include, too.
4638 [Ralf S. Engelschall] PR#2777
4640 *) PORT: Added RHAPSODY (Mac OS X Server) support. MAP_TMPFILE defined
4641 as an alternate mechanism for mmap'd shared memory for RHAPSODY.
4642 ap_private_extern defined to hide symbols that conflict with loaded
4643 dynamic libraries on the NEXT and RHAPSODY platforms.

4659 [Jeff Stewart <jws@purdue.edu>] PR#2790
4661 *) Add some more LIBS for the SCO5 platform which are needed for the already
4662 used -lprot. It's actually a bug in SCO5, of course.

4665 *) Fix documentation of ProxyPass/ProxyPassReverse according to the
4666 trailing slash problem. [Jon Drukman <jsd@gamespot.com>] PR#2933
4668 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
4669 platform, because it's only supported under version 4.0 and higher. But
4670 because our GuessOS is still unaware of Digital UNIX versions and the
4671 -msym is just to optimize the DSO statup time a little bit it's safe and
4672 best when we leave it out now. [Ralf S. Engelschall] PR#2969
4674 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
4675 functions: First all three functions no longer fail on strings containing
4676 "%" chars and second ap_log_printf() no longer does a double-formatting
4677 (instead it directly passes through the message to be formatted to the
4678 real internal formatting function). [Ralf S. Engelschall] PR#2941
4680 *) Allow "Include" directives anywhere in the server config
4681 files (but not .htaccess files). [Ken Coar] PR#2727
4683 *) The proxy was refusing to serve CONNECT requests except to
4684 port 443 (https://) and 563 (snews://). The new AllowCONNECT
4685 directive allows the configuration of the ports to which a
4686 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4688 *) mod_expires will now act on content that is not sent from a file
4689 on disk. Previously it would never add an Expires: header to
4690 any response that did not come from a file on disk; the only
4691 case where it still doesn't (and can't) add one for that type of
4692 content is if you are using a modification date based setting.
4693 [Marc Slemko, Paul Phillips <paulp@go2net.com>]
4695 *) Problems encountered during .htaccess parsing or CGI execution
4696 that lead to a "500 Server Error" condition now provide explanatory
4697 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
4700 *) Add NameWidth keyword to IndexOptions directive so that the
4701 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
4704 *) Recognize lowercase _and_ uppercase `uname' results under
4705 SCO OpenServer. [David Coelho <drc@ppt.com>]
4707 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4708 a common problem of (mis-administrated?) IIS servers, make the apache
4709 proxy immune to these errors (and ignore the duplicates, but log
4710 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4712 *) The <IfModule and <IfDefine block starting directives now only
4713 allow exactly one argument. Previously, the optional negation
4714 character '!' could be separated by whitespace without a syntax
4715 error being reported, albeit defeating the IfModule functionality
4716 (enclosed directives would ALWAYS be executed). By using the
4717 stricter syntax, these hard-to-track errors can be avoided.
4720 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4721 cause the standalone FancyIndexing directive to logically OR
4722 into any existing IndexOptions settings rather than wiping
4723 them out. [Ken Coar]
4725 *) Changes in ftp proxy: make URL parsing simpler by using the
4727 + Add display of the "current directory" in cases where it's
4728 different from the supplied path (e.g., ftp://user@host/ lives
4729 in /home/user, not in /, therefore clicking on "../" in the
4730 starting directory might send us to /home/).
4731 + When ftp login fails, (esp. when a user name was part of the
4732 URL already), we now return [401 Unauthorized ] to allow the
4733 browser to pop up an authorization dialog. This makes passwords
4734 slightly less visible (they don't appear in the regular log files)
4735 and implements a functionality that other www proxy servers
4739 *) Triggered by the recent "Via:" header changes, the proxy module would
4740 dump core for replies with invalid headers (e.g., duplicate
4741 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4742 core dump is avoided. Also, broken replies are not cached.
4743 [Martin Kraemer] PR#2914
4745 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4746 plop gmon.out profile data for each child [Doug MacEachern]
4748 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
4749 config.status script to be immune against arguments with whitespaces.
4750 [Yves Arrouye <yves@apple.com>] PR#2866
4752 *) Replace the inlined information grabbing stuff for the configuration
4753 adjustment feature (no --without-confadjust) with calls to a new helper
4754 script `buildinfo.sh' which is both more flexible and already proofed to
4755 be more robust against platform differences. This mainly fixes the
4756 recently occured ``sed: command garbled: ...'' problems.
4757 [Ralf S. Engelschall] PR#2776, PR#2848
4759 *) Make ab.c again pass ``gcc -Wall -Wshadow -Wpointer-arith -Wcast-align
4760 -Wmissing-prototypes -Wmissing-declarations -Wnested-externs -Winline''
4761 without complains after we recently added the POST feature.
4762 [Ralf S. Engelschall]
4764 *) Renamed is_HTTP_xxx() macros to ap_is_HTTP_xxx() name. They are used inside
4765 modules as API functions and we forgot them at the big symbol renaming.

4768 *) Remove bad reference to non-existing SERVER_VERSION in mod_rewrite.html

4774 *) Add the ability to do POST requests to the ab benchmarking tool.
4775 [Kurt Sussman <kls@best.com>] PR#2871
4777 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4778 5 to 10 because there are some users out there who always have 5 to 8
4779 variables in one RewriteRule and had to patch mod_rewrite.h for every
4780 release. So 15 should be now more than enough, even for them. (I never
4781 needed more than 4 in my RewriteRules ;-)
4782 [Ralf S. Engelschall]
4784 *) Make the proxy generate and understand Via: headers
4787 *) Change the proxy to use tables instead of array_headers for
4788 the header lines. [Martin Kraemer]
4790 *) Make sure the config.status file is not overridden when just
4791 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
4793 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
4794 provide a way to trace API changes that add functionality but do
4795 not create a compatibility issue for precompiled modules, etc.
4796 See include/ap_mmn.h for more details. [Randy Terbush]
4798 *) Fix suexec installation under `make install root=xxx' situation.
4799 [Ralf S. Engelschall]
4801 *) Extend the output of the -V switch to include the paths of all
4802 compiled-in configuration files, if they were overridden at
4803 compile time, for least astonishment of the user.
4806 *) When READing a request in ExtendedStatus mode, the "old"
4807 vhost, request and client information is not displayed.
4810 *) STATUS is no longer available. Full status information now
4811 run-time configurable using the ExtendedStatus directive.
4814 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4815 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4816 a function which can be used to perform bulk update operations
4817 on tables in a more efficient manner. [Dean Gaudet]
4819 *) SECURITY: Added compile-time and configurable limits for
4820 various aspects of reading a client request to avoid some simple
4821 denial of service attacks, including limits on maximum request-line
4822 size (LimitRequestLine), number of header fields (LimitRequestFields),
4823 and size of any one header field (LimitRequestFieldsize). Also added
4824 a configurable directive LimitRequestBody for limiting the size of the
4825 request message body. [Roy Fielding]
4827 *) Make status module aware of DNS and logging states, even if
4828 STATUS not defined. [Jim Jagielski]
4830 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
4832 *) Enhance mod_speling so that CheckSpelling can be used in
4833 <Directory> containers and .htaccess files. [Ken Coar]
4835 *) API: new ap_custom_response() function for hooking into the
4836 ErrorDocument mechanism at runtime [Doug MacEachern]
4838 *) API: new ap_uuencode() function [Doug MacEachern]
4840 *) API: scan_script_header_err_core() now "public" and renamed
4841 ap_scan_script_header_err_core() [Doug MacEachern]
4843 *) The 'status' module will now show the process pid's and their
4844 state even without full STATUS accounting. [Jim Jagielski]
4846 *) Restore the client IP address to the error log messages, this
4847 was lost during the transition from 1.2 to 1.3. Add a new
4848 function ap_log_rerror() which takes a request_rec * and
4849 formats it appropriately. [Dean Gaudet] PR#2661
4851 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4852 whitespace in input lines -- including within quoted strings.
4854 but leading and trailing whitespace should continue to be
4855 stripped [Martin Kraemer]
4857 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4858 the ugly use of an env. variable and use command-line args for
4859 alternate $PATH. Make more like advanced 'type's as well.
4862 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
4863 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
4864 <alain.st-denis@ec.gc.ca>] PR#2736
4866 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
4868 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
4869 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
4870 directory was renamed to src/os/os2/ for consistency.
4871 [Brian Havard, Ralf S. Engelschall]
4873 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4874 files (here modules) against other DSO files (here shared libraries).
4875 This is done by determining a subset of LIBS which can be safely used for
4876 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4877 disabled for all platforms to avoid problems with this (experimental)
4878 rule. But we provide it now for those people how ran into problems and
4879 want to came out by forcing linking against DSOs.

4882 *) Fix suEXEC start message: Has to be of `notice' level to really get

4899 and sed in top-level configure script to avoid sed fails on some

5012 Backward compatibility files for conf.h and compat.h were created.
5014 *) mod_mmap_static will no longer take action on requests unless at
5015 least one "mmapfile" directive is present in the configuration.
5016 This experimental module has to do some black magic to operate
5017 inside the current API and thus creates side-effects for other

5076 if the installation prefix didn't already contain "apache", but
5077 it should be because the DSO files are Apache-specific. Now

5128 which of three dozen different versions of "ps" are installed.
5131 *) WIN32: If we can't figure out how to execute a file in a script
5132 directory, bail out of the request with an error message. [W G Stoddard]
5134 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
5135 these are treated by Win32 as if they are ".." but are not detected by
5136 other machinery within Apache. This is something of a kludge but
5137 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5139 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5140 pools and thus pollutes libap (until the pool stuff is moved there).
5143 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
5144 but case-insensitive platforms). New #define for this added to conf.h

5154 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5155 remove some of the classical hurdles for new users when setting up
5156 Apache. This is done per default because it is useful for the average
5157 user. Package authors can use the --without-confadjust option to disable
5158 these configuration adjustments.
5159 [Ralf S. Engelschall]
5161 *) Added an EXTRA_DEPS configuration parameter which can be used
5162 to add an extra Makefile dependency for the httpd target, for instance
5163 to external third-party libraries, etc.
5164 [Ralf S. Engelschall]
5166 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5167 as <IfModule>..</IfModule> sections) which can be used to skip or process
5168 contained commands dependend of ``-D PARAMETER'' options on the command
5169 line. This can be used to achieve logical conditions like <IfDefine
5170 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5171 and thus especially can be used for conditionally loading DSO-based
5172 modules via LoadModule, etc. [Ralf S. Engelschall]

5179 truncated which forced following HTTP headers to be data in the HTTP
5180 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5183 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5184 in top-level configure script to avoid sed fails on some platforms (for
5185 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5186 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5188 *) Improve performance of directory listings (mod_autoindex) by comparing
5189 integer keys (last-modified and size) as integers rather than converting
5190 them to strings first. Also use a set of explicit byte tests rather
5191 than strcmp() to check for parent directory-ness of an entry. Oh, and
5192 make sure the parent directory (if displayed) is *always* listed first
5193 regardless of the sort key. Overall performance winnage should be good
5194 in CPU time, instruction cache, and memory usage, particularly for large
5195 directories. [Ken Coar]
5197 *) Add a tiny but useful goody to APACI's configure script: The generation
5198 of a config.status script (as GNU Autoconf does) which remembers the used
5199 configure command and hence can be used to restore the configuration by
5200 just re-running this script or for remembering the configuration between
5202 [Ralf S. Engelschall]
5204 *) Add httpd -t (test) option for running configuration syntax tests only.
5205 If something is broken it complains and exits with a return code
5206 non-equal to 0. This can be used manually by the user to check the Apache
5207 configuration after editing and is also automatically used by apachectl
5208 on (graceful) restart command to make sure Apache doesn't die on restarts
5209 because of a configuration which is now broken since the last (re)start.
5210 This way `apachectl restart' can be used inside cronjobs without having
5211 to expect Apache to be falling down. Additionally the httpd -t can be run
5212 via `apachectl configtest'.

5362 generated Makefile more user friendly. [Ralf S. Engelschall]
5364 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5365 was updated to use the normal apache error processing, thereby allowing
5366 proxy errors to be treated by ErrorDocument's as well. For this
5367 purpose, a new module-to-core communication variable "error-notes"
5368 was introduced; the proxy (and possibly other modules) communicates
5369 its error text using this variable. Its content is copied to a new
5370 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5371 The old proxy special error routine ap_proxy_log_uerror()

5381 ("make") of Apache we can allow, of course. Root privileges are needed

5429 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
5430 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
5433 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
5435 *) Fix support script `dbmmanage': It was unable to handle some sort
5436 of passwords, especially passwords with "0" chars.
5437 [Ralf S. Engelschall] PR#2242
5439 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5440 [Ben Laurie] PR#2238
5442 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5443 library), so CGI handling has been changed to use Win32 native handles
5444 instead of C file descriptors.
5445 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5447 *) The proxy cache would store an incorrect content-length in the cached
5448 file copy after a cache update. That resulted in repeated fetching
5449 of the original copy instead of using the cached copy.
5450 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5452 *) The Makefiles assumed that DSO files are build via $(LD). This
5453 is broken for two reasons: First we never defined at least LD=ld
5454 somewhere to make sure this works (it was silently assumed that most Make
5455 provide a built-in LD definition - ARGL!) and second using the generic LD
5456 variable is not the truth. Instead a special variable named LD_SHLIB is
5457 reasonable because although "ld" is usually the default, the command for
5458 building DSO files can be "libtool" or even "cc" on some systems.
5459 [Ralf S. Engelschall]
5461 *) Replace the AddVersionPlatform directive with ServerTokens which
5462 provides for more control over the format of the Server:
5463 header line. SERVER_SUBVERSION is no longer supported;
5464 all module should use the ap_add_version_component()
5465 API function instead. [Jim Jagielski]
5467 *) Support for the NCR MP/RAS 3.0
5468 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5470 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5471 not retrieved in src/Configure and thus was not useable.
5472 [Ralf S. Engelschall]
5474 *) Various Makefile consistency cleanups:
5475 - make OSDIR also automatically be relative to src/ like INCDIR
5476 - SUBDIRS is now generated in src/Makefile only and not in
5477 Makefile.config because it is a local define for this location.
5478 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5479 any Makefile but make sure that at least the "-K inline" is kept in
5481 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5482 - updated the dependencies theirself
5483 - removed not existing SHLIB variable from "clean" targets
5484 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5485 already exists and OBJS_PIC are also just plain objects and have not
5486 directly to do with "shared" things. The only difference is that they
5487 contain PIC. So OBJS_PIC is the more canonical name.
5488 - Updated the Makefile-dependency lines for OBJS_PIC
5489 - Removed the Makefile-dependency line in Configure to avoid double
5491 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5492 of xxx.lo as GNU libtool does with its PIC objects
5493 - reduce local complexity in modules Makefile.tmpl by moving the last
5494 existing target "depend" to the generation section in Configure, too.
5495 - removed the historical $(SPACER) which was used in the past together
5496 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5497 is no longer needed.
5498 - force the build and run of the gen_xxx programs under main/ as the
5499 first step before building the objects because it looks cleaner
5500 [Ralf S. Engelschall]
5502 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5505 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5508 *) WIN32: Don't force ISAPI headers to finish with \n.
5509 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5511 *) When opening "configuration" files (like httpd.conf, htaccess
5512 and htpasswd), Apache will not allow them to be non-/dev/null
5513 device files. This closes a DoS hole. At the same time,
5514 we use ap_pfopen to open these files to handle timeouts.
5515 [Jim Jagielski, Martin Kraemer]
5517 *) Apache will now log the reason its httpd children exit if they exit
5518 due to an unexpected signal. (It requires a new porting define,
5519 SYS_SIGLIST, which if defined should point to a list of text
5520 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5522 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5523 like WIN32. Before, Win32 CGI's could have had sporadic failures
5524 if a chdir call from one thread was made between another chdir call
5525 and a spawn in another thread. So, for now don't chdir for CGI scripts
5526 in WIN32. The current CGI "spec" is unclear as to whether it's
5527 necessary. Long-term fix is to either serialize the chdir/spawn combo
5528 or use WIN32 native calls to spawn a process. This temp fix was
5529 necessary to remove this as a showstopper for 1.3's release.
5532 *) Cleanup the suEXEC support in APACI and make it more safe:
5533 1. Add big fat hint in INSTALL about risks and to read the
5534 htdocs/manual/suexec.html document before using the suexec-related
5536 2. Make sure the user has at least provided one --suexec-xxxx option
5537 (specifies suEXEC parameters) in addition to --enable-suexec option.
5538 If only --enable-suexec is given APACI stops with a hint to INSTALL
5539 and htdocs/manual/suexec.html documents.
5540 3. Provide two additional --suexec-xxxx options to make the suEXEC
5541 configuration complete (especially for package maintainers who else
5542 had to patch the source tree) by providing ways to configure minimal
5543 UID/GID and safe PATH, too.
5544 [Ralf S. Engelschall]
5546 *) Cleanup of the `configure --shadow' process:
5547 - make sure the configure script creates its temporary files in the
5548 shadow tree to avoid conflicts with parallel configure runs
5549 - removed unnecessary option "-r" from "rm" call for Makefiles
5550 - make sure the configure scripts creates the shadow-wrapper Makefile
5551 only when no shadow trees already exists
5552 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5553 when no more shadow trees exists
5554 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5555 as fast (in the past it needed 70sec, now it runs just 38sec)
5556 - make sure CVS does not complain about the created files
5557 Makefille.<gnutriple> and directories src.<gnutriple>
5558 [Ralf S. Engelschall]
5560 *) Added the ap_add_version_component() API routine and the
5561 AddVersionPlatform core directive. The first allows modules to
5562 declare themselves in the Server response header field value,
5563 augmenting the SERVER_SUBVERSION define in the Configuration file
5564 with run-time settings (more useful in a loadable-module environment).
5565 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5566 into the server version string. [Ken Coar] PR#2056
5568 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5571 *) Emit the "Accept-Range" header for the default handler.
5572 [Brian Behlendorf] PR#1464
5574 *) Add a note to httpd.conf-dist that apache will on some systems fail
5575 to start when the Group # is set to a negative or large positive value.
5578 *) Make sure the module execution order is correct even when some modules
5579 are loaded under runtime (`LoadModule') via the DSO mechanism:
5580 1. The list of loaded modules is now a dynamically allocated one
5581 and not the original statically list from modules.c
5582 2. The loaded modules are now correctly setup by LoadModule for
5583 later use by the AddModule command.
5584 3. When the DSO mechanism for modules is used APACI's `install'
5585 target now enables all created `LoadModule' lines per default because
5586 this is both already expected by the user _and_ needed to avoid
5587 confusion with the next point and reduces the Makefile.tmpl complexity
5588 4. When the DSO mechanism for modules is used, APACI's `install'
5589 target now additionally makes sure the module list is reconstructed
5590 via a complete `ClearModuleList+AddModule...' entry.
5591 5. The support tool `apxs' now also makes sure an AddModule command
5592 is added in addition to the LoadModule command.
5593 6. The modules.c generation was extended to now contain two
5594 comments to make sure no one is confused by the confusing terminology
5595 of loading/linking (we use load=link+load & link=activate instead of
5596 the obvious load=activate & link=link :-( )
5597 This way now there is no longer a difference under execution time between
5598 statically and dynamically linked modules.
5599 [Ralf S. Engelschall]
5601 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5602 Big Symbol Renaming. [Ralf S. Engelschall]
5604 *) Add a comment to mod_example.c showing the format of a FLAG command
5607 *) Standardized the time format in mod_status to match that of other
5608 places in the code (e.g. DATE_GMT). PR#1551
5610 *) Fix handling of %Z in timefmt strings for those platforms with no time
5611 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5614 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5615 feature compatible with 'UseCanonicalName off' by changing
5616 r->server->server_hostname to ap_get_server_name(). And I changed some
5617 functions which use r->server->port to use ap_get_server_port() instead,
5618 because if there's no Port directive in the config r->server->port is 0.
5621 *) get/set_module_config are trivial enough to be better off inline. Worth
5622 1.5% performance boost. [Dean Gaudet]
5624 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5625 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5628 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5629 the task environment to the unprivileged User id. Otherwise CGI scripts
5630 would have a way to gain super user access. [Martin Kraemer]
5632 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5633 absolute path, only log base name of logging source as is done
5634 in unix. [Martin Kraemer]
5636 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5637 the encoding type from the Accept-Encoding header (if it's there)
5638 and use it in the response, as that's probably what it'll be expecting.
5639 [Ronald.Tschalaer@psi.ch]
5641 *) Fix to mod_alias: translate_alias_redir is dealing with
5642 a URI, not a filename, so the check for drive letters for win32
5643 and emx is not necessary. [Dean Gaudet]
5645 *) WIN32: Allow .cmd as an executable extension.
5646 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
5648 *) Make Apache header files, and some variables, C++ friendly.
5649 [Michael Anderson's <mka@redes.int.com.mx>]
5651 *) Child processes can now "signal" (by exiting with a status
5652 of APEXIT_CHILDFATAL) the parent process to abort and
5653 shutdown the server if the error in the child process was
5654 fatal enough. [Jim Jagielski]
5656 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5657 [Jim Jagielski] PR#2112
5659 *) Make sure the referer_log and agent_log entries in the default httpd.conf
5660 file are also adjusted for the actual relative installation paths.
5661 [Ralf S. Engelschall] PR#2175
5663 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5665 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5668 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5669 Additionally the checks for finding the vendor DSO library were moved
5670 from mod_so.c to Configure because first it needs $PLAT etc. and second
5671 mod_so already uses an abstraction layer and does not fiddle with the
5672 vendor functions itself.
5673 [Jens-Uwe Mager, Ralf S. Engelschall]
5675 *) PORT: Some optimization defines for NetBSD
5676 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5678 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5679 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5681 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5682 AIX variants should work fine, too. Even AIX 3.x should work). This is
5683 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5684 which we put into a os/unix/os-dso-aix.c file.
5685 [Ralf S. Engelschall]
5687 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5688 that we should use NET_SIZE_T == int but the include files force size_t.
5689 [Ralf S. Engelschall]
5691 *) Fix two bugs in select() handling in http_main.c.
5694 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5695 is unset (as it is in situations like timeouts) where it is unclear
5696 whether errno is set or not. [Martin Kraemer]
5698 *) Just having APACI's localstatedir is too general and not enough for most
5699 of the systems. 1.3b6 again required manual APACI patches by package
5700 maintainers from RedHat and FreeBSD because for their filesystem layout a
5701 little bit more flexibility in configuring the paths is needed. Hence we
5702 provide three additional configure options (--runtimedir, --logfiledir,
5703 --proxycachedir) which now can be used for more granular adjustments if
5704 --localstatedir is not enough to fit the particular needs. As a nice
5705 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5706 [Ralf S. Engelschall]
5708 *) Make the install root for "make install" in APACI's Makefile overrideable
5709 by package authors. This way we are even more friendly to package
5710 maintainers (especially Debian and RedHat) who build for the real prefix
5711 via "configure --prefix=/<real>" but use a different local prefix via
5712 "make root=/tmp/apache install" for rolling the package without bristling
5713 the target location on their system.
5714 [Ralf S. Engelschall]
5716 *) Workaround sed limitations in APACI's configure script by now
5717 substituting in chunks of 50 commands (because for instance HPUX's vendor
5718 sed has a limit of max. 98 commands)
5719 [Ralf S. Engelschall] PR#2136
5721 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5722 [Ralf S. Engelschall] PR#2140
5724 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5725 RENAMING process because they are defined as pre-processor macros instead
5726 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5727 [Ralf S. Engelschall]
5729 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5730 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5731 [Ralf S. Engelschall] PR#2139
5733 *) Various bugfixes and cleanups for the APACI configure script:
5734 o fix IFS handling for _nested_ situation
5735 o fix Perl interpreter search: take first one found instead of last one
5736 o fix DSO consistency check
5737 o print error messages to stderr instead of stdout
5738 o add install-quiet for --shadow situation to Makefile stub
5739 o reduce complexity by avoiding sed-hacks for rule and module list loops
5740 [Ralf S. Engelschall]
5742 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5744 *) Make sure the input field separator (IFS) shell variable is explicitly
5745 initialized correctly before _every_ `for' loop and also restored after
5746 the loops. [Ralf S. Engelschall]
5748 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5749 `magic' files from an existing Apache installation. Because people often
5750 customize these for own MIME and content types.
5751 [Ralf S. Engelschall]
5753 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
5754 [Peter Galbavy, Ralf S. Engelschall] PR#2109
5756 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5757 [Ralf S. Engelschall] PR#2105
5759 *) Let "configure" clear out the users parameters (provided as shell
5760 variables) to avoid side-effects in "src/Configure" when the user
5761 exported them (which is not needed, but some users do it).
5762 [Ralf S. Engelschall] PR#2101
5764 *) Provide backward compatibility from some old src/Configuration.tmpl
5765 parameter names to the canonical Autoconf-style shell variable names. For
5766 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
5767 but a hint message is displayed. [Ralf S. Engelschall]

5770 CGI scripts from an existing Apache installation.
5771 [Ralf S. Engelschall, Jim Jagielski] PR#2084
5773 *) Make `configure --compat' more "compatible" by first
5774 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5775 second by making sure the "avoid-bristling-suffix" /apache is not
5776 appended to sysconfdir, datadir, localstatedir and includedir when

5785 *) Fix the path to the MimeMagicFile in the install-config target, too.
5786 [Ralf S. Engelschall] PR#2089
5788 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5790 *) If you start apache with the -S command line option it will dump
5791 out the parsed vhost settings. This is useful for folks trying
5792 to figure out what is wrong with their vhost configuration.
5793 (Other dumps may be added in the future.) [Dean Gaudet]
5795 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5796 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5799 *) Because /usr/local/apache is the default prefix the ``configure
5800 --compat'' option no longer has to set prefix, again. This way the
5801 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5803 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5804 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5805 to avoid "discard const" warnings. [Ralf S. Engelschall]
5807 *) If a specific handler is set for a file yet the request still
5808 ends up being handled by the default handler, log an error
5809 message before handling it. This catches things such as trying
5810 to use SSIs without mod_include enabled. [Marc Slemko]
5812 *) Fix error logging for the startup case where ap_log_error() still uses
5813 stderr as the target. Now the default log level is honored here, too.
5814 [Ralf S. Engelschall]
5816 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5817 long" errors when generating the MODULES entry for src/Makefile
5818 [Ben Hyde, Ralf S. Engelschall]
5820 *) Make sure src/Configure doesn't complain about the old directory
5821 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5823 Changes with Apache 1.3b6
5825 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5827 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5828 interface via the similar but proprietary HP/UX shl_xxx-style system
5829 calls. [Ralf S. Engelschall]
5831 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5832 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5833 Make. [Ralf S. Engelschall]
5835 *) ++++ THE BIG SYMBOL RENAMING ++++
5836 To avoid symbol clashes with third-party code compiled into the server,
5837 we globally applied the prefix "ap_" to the following classes of
5839 - Apache provided general functions (e.g., ap_cpystrn)
5840 - Public API functions (e.g., palloc, bgets)
5841 - Private functions which we can't make static (because of
5842 cross-object usage) but should be (e.g., new_connection)
5843 For backward source compatibility a new header file named compat.h was
5844 created which provides defines for the old symbol names and can be used
5845 by third-party module authors.
5848 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5849 problem under SVR4 is that there is no command flag to force the linker
5850 to export the global symbols of the httpd executable therewith they are
5851 available to the DSO's. Instead of problematic hacks like creating a
5852 dummy.so file (containing dummy references to all global symbols) the
5853 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5854 Placing the Apache core code itself into a DSO library named libhttpd.so.
5855 This way the global symbols _HAVE_ to be exported and thus are available
5856 to any manually loaded DSO's under runtime. To reduce the impact to the
5857 user to null we go even further and create a stub httpd executable which
5858 automatically keeps track of the DSO library loading itself and thus
5859 hides the complete mechanism from the user. Although the generation of
5860 this DSO library is automatically triggered for platforms which
5861 essentially need it (mostly all SVR4-derivates) it can be also enabled
5862 manually via the Rule SHARED_CORE. This can be interesting in the future
5863 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5864 features like graceful upgrades, or whatever.
5865 [Ralf S. Engelschall, Martin Kraemer]
5867 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5869 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5870 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5871 conventions while "clean" removes only stuff created by "all" targets,
5872 "distclean" additionally removes the stuff from the configuration
5873 process. This way "make distclean" (hence the name) provides a fresh
5874 source tree as it was for distribution.
5875 [Ralf S. Engelschall]
5877 *) Allow top-level (APACI) Makefile to break on build errors
5878 the same way the src/ subtree Makefiles breaks on them by replacing the
5879 initial APACI sed-subdir-display-kludge with a more clean
5880 variable-passing-solution: variable SDP can optionally hold the subdir
5881 prefix which is consistently used for displaying the subdir movement.
5882 This way even the top-level Makefile can stop correctly on errors as the
5883 user expects. [Ralf S. Engelschall]
5885 *) Fixed ordering of argument checks for RewriteBase directive.
5886 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5888 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5889 indicating that a module is being compiled for dynamic loading. Also
5890 remove #define IS_MODULE from modules and add SHARED_MODULE define
5891 to the mak/dsp files. [Alexei Kosut]
5893 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5894 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5896 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5898 *) Add documentation file and src/Configuration.tmpl entry for the
5899 experimental mod_mmap_static module. Because although it is and marked as
5900 an experimental one it is distributed and thus should be documented and
5901 prepared for configuration the same way as all others modules.
5902 [Ralf S. Engelschall]
5904 *) Add query (-q) option to apxs support tool to be able to manually query
5905 specific settings from apxs. This is needed for instance when you
5906 manually want to access Apache's header files and you need to assemble
5907 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5908 [Ralf S. Engelschall]
5910 *) Now src/Configure uses a fallback strategy for the shared object support
5911 on platforms where no explicit information is available: If a Perl
5912 installation exists we ask it about its shared object support and if it's
5913 the dlopen-style one we shamelessly guess the compiler and linker flags
5914 for creating shared objects from Perls knowledge. Of course, the user is
5915 warning about what we are doing and informed that he should send us
5916 the guessed flags when they work. [Ralf S. Engelschall]
5918 *) Provide APACI --without-support option to be able to disable the build
5919 and installation of the support tools from the src/support/ area.
5920 Although its useful to have these installed per default we should provide
5921 a way to compile and install without them for backward-compatibility.
5922 [Ralf S. Engelschall]
5924 *) Add of the new APache eXtenSion (apxs) support tool for building and
5925 installing modules into an _already installed_ Apache package through the
5926 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5927 this approach actually doesn't need the Apache source tree. The
5928 (APACI-installed) server package is enough, because this now includes the
5929 Apache C header files (PREFIX/include) and the new APXS tool
5930 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5931 module authors to build their Apache modules _OUTSIDE_ the Apache source
5932 tree while avoiding them to fiddle around with the totally platform
5933 dependend way of compiling DSO files. The tool supports all ranges of
5934 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5935 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5936 on-the-fly generate a minimalistic Makefile and sample module for the
5937 first step to provide both a quick success event and to demonstrate the
5938 APXS mechanism to module authors. [Ralf S. Engelschall]
5940 *) Fix core dumps in use of CONNECT in proxy.
5941 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5943 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5944 so that users have examples of how CustomLog can be used.
5947 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5948 the Apache distribution tree. Until Apache 1.3 there was no real
5949 out-of-the-box batch-capable build and installation procedure for the
5950 complete Apache package. This is now provided by a top-level "configure"
5951 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5952 to provide a GNU Autoconf-style frontend which is capable to both drive
5953 the old src/Configure stuff in batch and additionally installs the
5954 package with a GNU-conforming directory layout. Any options from the old
5955 configuration scheme are available plus a lot of new options for flexibly
5956 customizing Apache. [Ralf S. Engelschall]
5958 *) The floating point ap_snprintf code wasn't threadsafe.
5959 Had to remove the HAVE_CVT macro in order to do threadsafe
5960 calling of the ?cvt() floating point routines. [Dean Gaudet]
5962 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
5964 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler

5967 *) BUG: Configure was using TCC and CC inconsistently. Make sure
5968 Configure knows which CC we are using. [Jim Jagielski]
5970 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5971 was defined in a parent directory. [Lars Eilebrecht]
5973 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5974 a generic printf-style routine that can call arbitrary output
5975 routines. Use this to replace http_bprintf.c. Add new routines
5976 psprintf(), pvsprintf() which allocate the exact amount of memory
5977 required for a string from a pool. Use psprintf() to clean up
5978 various bits of code which used ap_snprintf()/pstrdup().
5981 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5982 ap_snprintf() has different semantics and formatting codes than
5983 snprintf(). [Dean Gaudet]
5985 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5986 is necessary on at least Solaris where the /etc/rc?.d scripts
5987 are run with these signals ignored, and "SIG_IGN" settings are
5988 maintained across exec().

5999 *) A few changes to scoreboard definitions which helps gcc generate
6000 better code. [Dean Gaudet]
6002 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
6003 be a signed bitfield. So mark a few bitfields as signed to
6004 ensure correct code. [Dean Gaudet]
6006 *) The default for HostnameLookups was changed to Off, but there
6007 was a problem and it wasn't taking effect. [Dean Gaudet]
6009 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
6012 *) After a SIGHUP the listening sockets in the parent weren't
6013 properly marked for closure on fork().
6014 [Jürgen Keil <jk@tools.de>] PR#2000
6016 *) Allow %2F in two situations: 1) it is in the query part of the URI,
6017 therefore not exposed to %2F -> '/' translations and 2) the request
6018 is a proxy request, so we're not dealing with a local resource anyway.
6019 Without this, the proxy would fail to work for any URL's with
6020 %2f in them (occurs quite often in
6021 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
6023 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
6025 *) Make the shared object compilation command more portable by avoiding
6026 the direct combination of `-c' & `-o' which is not honored by some
6027 compilers like UnixWare's cc. [Ralf S. Engelschall]
6029 *) WIN32: the proxy was creating filenames missing the last four
6030 characters. While this normally doesn't stop anything from
6031 working, it can result in extra collisions.
6032 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
6034 *) Now mod_proxy uses the response string (in addition to the response status
6035 code) from the already used FTP SIZE command to setup the Content-Length
6036 header if available. [Ralf S. Engelschall] PR#1183
6038 *) Reanimated the (still undocumented) proxy receive buffer size directive:
6039 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
6040 name was really too generic, added documentation for this directive to
6041 the mod_proxy.html and corrected the hyperlink to it in the
6042 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
6044 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
6045 faster [Martin Kraemer]
6047 *) Make Configure die when you give it an unknown command switch.
6050 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
6051 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
6052 and per default compiled support programs have manual pages - just to
6053 document our stuff a little bit more and to be able to do really
6054 Unix-like installations ;-) [Ralf S. Engelschall]
6056 *) Major cleanups to the Configure script to make it and its generated
6057 Makefiles again readable and maintainable: add SRCDIR option, removed
6058 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
6059 generated sections, consequently added Makefile headers with inheritance
6060 information, added subdir movement messages for easier following where
6061 the build process currently stays (more verbose then standard Make, less
6062 verbose than GNU make), same style to comments in the Configure script,
6063 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
6065 *) Add the new ApacheBench program "ab" to src/support/: This is derived
6066 from the ZeusBench benchmarking program and can be used to determine the
6067 response performance of an Apache installation. This version is
6068 officially licensed with Zeus Technology, Ltd. See the license agreement
6069 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
6070 [Ralf S. Engelschall]
6072 *) API: Various core functions that are definately not part of the API
6073 have been made static, and a few have been marked API_EXPORT. Still
6074 more have been marked CORE_EXPORT and are not intended for general
6075 use by modules. [Doug MacEachern, Dean Gaudet]
6077 *) mod_proxy was not clearing the Proxy-Connection header from
6078 requests; now it does. This did not violate any spec, however
6079 causes poor interactions when you are talking to remote proxies.
6080 [Marc Slemko] PR#1741
6082 *) Various cleanups to the command line interface and manual pages.
6083 [Ralf S. Engelschall]
6085 *) cfg_getline() was not properly handling lines that did not end
6086 with a line termination character. [Marc Slemko] PR#1869, 1909
6088 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
6090 *) Clean up some undocumented behavior of mod_setenvif related to
6091 "merging" two SetEnvIf directives when they match the same header
6092 and regex. Document that mod_setenvif will perform comparisons in
6093 the order they appear in the config file. Optimize mod_setenvif by
6094 doing more work at config time rather than at runtime.
6097 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6098 to allow for modules to overrule them and to reduce redefinition
6099 warnings [Jim Jagielski]
6101 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6104 *) Making the hard-coded cross-module function call mime_find_ct() (from
6105 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6106 checking is really called even for proxy requests except for URLs with
6107 HTTP schemes (because there we can optimize by not running the type
6108 checking hooks due to the fact that the proxy gets the MIME Content-type
6109 from the remote host later). This change cleans up mod_mime by removing
6110 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6111 especially unbundles mod_proxy and mod_mime. This way they both now can
6112 be compiled as shared objects and are no longer tied together.
6113 [Ralf S. Engelschall]
6115 *) util.c cleanup and speedup. [Dean Gaudet]
6117 *) API: Clarification, pstrndup() will always copy n bytes of the source
6118 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6120 *) Mark module command_rec and handler_rec structures const so that they
6121 end up in the read-only data section (and are friendlier to systems
6122 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6124 *) Add check to the "Port" directive to make sure the specified
6125 port is in the appropriate range. [Ben Hyde]
6127 *) Performance improvements to invoke_handler().
6128 [Dmitry Khrustalev <dima@bog.msu.su>]
6130 *) Added support for building shared objects even for library-style modules
6131 (which are built from more than one object file). This now provides the
6132 ability to build mod_proxy as a shared object module. Additionally
6133 modules like mod_example are now also supported for shared object
6134 building because the generated Makefiles now no longer assume there is at
6135 least one statically linked module. [Ralf S. Engelschall]
6137 *) API: Clarify usage of content_type, handler, content_encoding,
6138 content_language and content_languages fields in request_rec. They
6139 must always be lowercased; and the strings pointed to shouldn't
6140 be modified (you must copy them to modify them). Fix a few bugs
6141 related to this. [Dean Gaudet]
6143 *) API: Clarification: except for RAW_ARGS, all command handlers can
6144 treat the char * parameters as permanent, and modifiable. There
6145 is no need to pstrdup() them. Clean up some needless pstrdup().
6148 *) Now mod_so keeps track of which module shared objects with which names
6149 are loaded and thus avoids multiple loading and unloading and irritating
6150 error_log messages. [Ralf S. Engelschall]
6152 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6153 environment variable in the apache core. But that tweaking interferes
6154 with mod_setenv. So don't tweak if the user has specified an explicit
6155 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6157 *) rputs() did not calculate r->sent_bodyct properly.
6158 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6160 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6161 name, or left unset if this value is unavailable. Apache was setting
6162 it to the IP address when unavailable.
6163 [Tony Finch <fanf@demon.net>] PR#1925
6165 *) Various improvements to the configuration and build support for compiling
6166 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6167 OSF1 support with GCC and vendor compilers was added. This way shared
6168 object support is now provided out-of-the-box for FreeBSD, Linux,
6169 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6170 [Ralf S. Engelschall]
6172 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6173 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6174 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6176 *) Fix one more special locking problem for RewriteMap programs in
6177 mod_rewrite: According to the documentation of flock(), "Locks are on
6178 files, not file descriptors. That is, file descriptors duplicated
6179 through dup(2) or fork(2) do not result in multiple instances of a lock,
6180 but rather multiple references to a single lock. If a process holding a
6181 lock on a file forks and the child explicitly unlocks the file, the
6182 parent will lose its lock.". To overcome this we have to make sure the
6183 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6184 the case by opening it in the child_init instead of the module_init API
6185 hook. [Ralf S. Engelschall] PR#1029
6187 *) Change to Location and LocationMatch semantics. LocationMatch no
6188 longer lets a single slash match multiple adjacent slashes in the
6189 URL. This change is for consistency with RewriteRule and
6190 AliasMatch. Multiple slashes have meaning in URLs that they do
6191 not have in (some) filesystems. Location on the other hand can
6192 be considered a shorthand for a more complicated regex, and it
6193 does match multiple slashes with a single slash -- which is
6194 also consistent with the Alias directive.
6195 [Dean Gaudet] related PR#1440
6197 *) Fix bug with mod_mime_magic causing certain files, including files
6198 of length 0, to result in no response from the server.
6201 *) The Configure script now generates src/include/ap_config.h which
6202 contains the set of defines used when Apache is compiled on a platform.
6203 This file can then be included by external modules before including
6204 any Apache header files in case they are being built separately from
6205 Apache. Along with this change, a couple of minor changes were
6206 made to make Apache's #defines coexist peacefully with any autoconf
6207 defines an external module might have. [Rasmus Lerdorf]
6209 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6210 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6211 chance by the API to initialize its per-server configuration and thus
6212 receives the wrong one from the main server. This is now avoided by
6213 remembering the server together with the config structure while
6214 configuring and later assuming there is no config when we see a
6215 difference between the remembered server and the one calling us.
6216 [Ralf S. Engelschall] PR#1790
6218 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6219 is automatically disabled under configure time when the dbm_xxx functions
6220 are not available. Second, two heavy source code errors in the DBM
6221 support code were fixed. This makes DBM RewriteMap's usable again after
6222 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6224 *) Now all configuration files support Unix-style line-continuation via
6225 the trailing backslash ("\") character. This enables us to write down
6226 complex or just very long directives in a more readable way. The
6227 backslash character has to be really the last character before the
6228 newline and it has not been prefixed by another (escaping) backslash.

6234 *) To deal with modules being compiled and [dynamically] linked
6235 at a different time from the core, the SERVER_VERSION and
6236 SERVER_BUILT symbols have been abstracted through the new
6237 API routines apapi_get_server_version() and apapi_get_server_built().
6240 *) WIN32: Preserve trailing slash in canonical path (and hence
6241 in PATH_INFO). [Paul Sutton, Ben Laurie]
6243 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6244 depending on the rev of Solaris and what mixture of modules
6245 are in use. So it has been disabled, and Solaris is back to
6246 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6247 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6248 up static content only servers. Or it may fail unpredictably.

6251 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6254 *) API: Rewrite of absoluteURI handling, and in particular how
6255 absoluteURIs match vhosts. Unless a request is a proxy request, a
6256 "http://host" url is treated as if a similar "Host:" header had been
6257 supplied. This change was made to support future HTTP/1.x protocols
6258 which may require clients to send absoluteURIs for all requests.
6260 In order to achieve this change subtle changes were made to the API. In a
6261 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6262 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6263 by the core, modules must set it during the post_read_request or
6264 translate_names phase.
6266 Plus changes to the virtualhost test suite for absoluteURI testing.
6268 This fixes several bugs with the proxy proxying requests to vhosts
6269 managed by the same httpd.
6272 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6273 code from mod_rewrite. The vhost matching is now performed by a
6274 globally available function matches_request_vhost(). [Dean Gaudet]

6290 *) API: A new source module main/util_uri.c; It contains a routine
6291 parse_uri_components() and friends which breaks a URI into its component
6292 parts. These parts are stored in a uri_components structure called
6293 parsed_uri within each request_rec, and are available to all modules.
6294 Additionally, an unparse routine is supplied which re-assembles the URI
6295 components back to an URI, optionally hiding the username:password@ part
6296 from ftp proxy requests, and other useful routines. Within the structure,
6297 you find on a ready-for-use basis:
6298 scheme; /* scheme ("http"/"ftp"/...) */
6299 hostinfo; /* combined [user[:password]@]host[:port] */
6300 user; /* user name, as in http://user:passwd@host:port/ */
6301 password; /* password, as in http://user:passwd@host:port/ */
6302 hostname; /* hostname from URI (or from Host: header) */
6303 port_str; /* port string (integer representation is in "port") */
6304 path; /* the request path (or "/" if only scheme://host was given) */
6305 query; /* Everything after a '?' in the path, if present */
6306 fragment; /* Trailing "#fragment" string, if present */
6307 This is meant to serve as the platform for *BIG* savings in
6308 code complexity for the proxy module (and maybe the vhost logic).
6311 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6312 ${map:key}) available for all location where a string is created in
6313 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6314 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6315 possible expansions are consequently usable at all string creation
6316 locations. [Ralf S. Engelschall]
6318 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6319 and not 1) and the per-virtual-server merging of directives. Now all
6320 directives except `RewriteEngine' and `RewriteOption' are either
6321 completely overridden (default) or completely inherited (when
6322 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6331 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6332 (like SunOS and FreeBSD) which don't accept the locking of pipes

6352 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6353 type but with a special post-processing for the looked-up value: It
6354 parses it into alternatives according to `|' chars and then only one
6355 particular alternative is chosen randomly (this is an essential
6356 functionality needed for balancing between backend-servers when using
6357 Apache as a Reverse Proxy. The looked up value here is a list of
6358 servers). Second, `int' with the built-in maps named `tolower' and
6359 `toupper' which can be used to map URL parts to a fixed case (this is an
6360 essential feature to fix the case of server names when doing mass
6361 virtual-hosting with the help of mod_rewrite instead of using
6362 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6363 Jay Soffian <jay@cimedia.com>] PR#1631
6365 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6366 This directive lets Apache adjust the URL in Location-headers on HTTP
6367 redirect responses sent by the remote server. This way the virtually
6368 mapped area is no longer left on redirects and thus by-passed which is
6369 especially essential when running Apache as a reverse proxy.

6480 *) MiNT port update. [Jan Paul Schmidt]
6482 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
6483 equivalent, similarly for x-compress and compress. Apache
6484 now ignores a leading x- when comparing encodings. It also
6485 preserves the encoding the client requests (for example if
6486 it requests x-gzip, then Apache will respond with x-gzip
6487 in the Content-Encoding header).

6490 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
6492 *) Added mod_so module to support dynamic loading of modules on Unix

6515 PR#315, 459, 485, 1433
6517 *) Yet another rearrangement of the source tree.. now all the common
6518 header files are in the src/include directory. The -Imain -Iap
6519 references in Makefiles have been changed to the simpler -Iinclude
6520 instead. In addition to simplifying the build a little bit, this
6521 also makes it clear when a module is referencing something in a
6522 other than kosher manner (e.g., the proxy including mod_mime.h).
6523 Module-private header files (the proxy, mod_mime, the regex library,
6524 and mod_rewrite) have not been moved to src/include; nor have
6525 the OS-abstraction files. [Ken Coar]
6527 *) Fix a bug where r->hostname didn't have the :port stripped
6528 from it. [Dean Gaudet]
6530 *) Tweaked the headers_out table size, and the subprocess_env
6531 table size guess in rename_original_environment(). Added
6532 MAKE_TABLE_PROFILE which can help discover make_table()
6533 calls that use too small an initial guess, see alloc.c.
6536 *) Options and AllowOverride weren't properly merging in the main
6537 server setting inside vhosts (only an issue when you have no
6538 <Directory> or other section containing an Options that affects
6539 a request). Options +foo or -foo in the main_server wouldn't
6540 affect the main_server's lookup defaults. [Dean Gaudet]
6542 *) Variable 'cwd' was being used pointlessly before being set.
6545 *) r->allowed handling cleaned up in the standard modules.
6548 *) Some case-sensitivity issues cleaned up to be consistent with
6549 RFC2068. [Dean Gaudet]
6551 *) SIGURG doesn't exist everywhere.
6552 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6554 *) mod_unique_id was erroneously generating a second unique id when
6555 an internal redirect occured. Such redirects occur, for example,
6556 when processing a DirectoryIndex match. [Dean Gaudet]
6558 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6559 of the key and value. But in many cases this is not required
6560 because the key/value is a constant, or the value has been built
6561 by pstrcat() or other similar means. New routines table_addn,
6562 table_mergen, and table_setn have been added to the API, these
6563 routines do not pstrdup() their arguments. The core code and
6564 standard modules were changed to take advantage of these routines.
6565 The resulting server is up to 20% faster in some situations.
6567 Note that it is easy to get code subtly wrong if you pass a key/value
6568 which is in a pool other than the pool of the table. The only
6569 safe thing to do is to pass key/values which are in the pool of
6570 the table, or in one of the ancestors of the pool of the table.
6571 i.e. if the table is part of a subrequest, a value from the main
6572 request's pool is OK since the subrequest pool is a sub_pool of the
6573 main request's pool (and therefore has a lifespan at most as long as
6574 the main pool). There is debugging code which can detect improper
6575 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6576 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6578 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6579 which don't exist on disk more gracefully; handles vhosts properly.
6580 Update documentation to reflect the code -- if there's no
6581 MimeMagicFile directive then the module is not enabled.
6584 *) PORT: Some older *nix dialects cannot automatically start scripts
6585 which begin with a #! interpreter line (the shell starts the scripts
6586 appropriately on these platforms). Apache now supports starting of
6587 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6588 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6591 *) API: "typedef array_header table" removed from alloc.h, folks should
6592 have been writing to use table as if it were an opaque type, but even
6593 some standard modules got this wrong. By changing the definition
6594 to "typedef struct table table" module authors will receive compile
6595 time warnings that they're doing the wrong thing. This change
6596 facilitates future changes with more sophisticated table
6597 structures. Specifically, module authors should be using table_elts()
6598 to get access to an array_header * for the table. [Dean Gaudet]
6600 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6601 library routines. [Ken Coar, Rasmus Lerdorf]
6603 *) WIN32: mod_speling is now available on the Win32 platform.
6606 *) For clarity the following compile time definition was changed:
6608 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6610 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6611 and not be a general notice that the OS has mmap(). Now the
6612 HAVE_MMAP/SHMGET #defines strictly are informational that the
6613 OS has that method of shared memory; the type to use for
6614 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6615 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6616 determine if shared memory is available and allows Apache
6617 to determine the best method to use for the scoreboard.
6620 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6621 as do various earlier versions. It should be safe on all versions.
6622 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
6623 the slack code. A few other cleanups for Unixware.

6627 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
6629 *) When die() happens we need to eat any request body if one exists.
6630 Otherwise we can't continue with a keepalive session. This shows up
6631 as a POST problem with MSIE 4.0, typically against pages which are
6632 authenticated. [Roy Fielding] PR#1399
6634 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization

6645 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
6646 The choice of flock vs. fcntl was made based on timings which showed that
6647 even on non-NFS, non-exported filesystems fcntl() was an order of
6648 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
6649 that single socket users will see no difference. [Dean Gaudet] PR#467
6651 *) "File does not exist" error message was erroneously including the
6652 errno. [Marc Slemko]
6654 *) Improve the warning message generated when a client drops the
6655 connection (hits stop button, etc.) during a send. [Roy Fielding]
6657 *) Defining GPROF will disable profiling in the parent and enable it

6659 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
6661 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.

6671 *) Some const declarations in mod_imap.c that were added for debugging
6672 purposes caused some compilers heartburn without adding any
6673 significant value, so they've been removed. [Ken Coar]
6675 *) The src/main/*.h header files have had #ifndef wrappers added to
6676 insulate them against duplicate calls if they get included through
6677 multiple paths (e.g., in .c files as well as other .h files).
6680 *) The libap routines now have a header file for their prototypes,
6681 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
6683 *) mod_autoindex with a plaintext header file would emit the <PRE>
6684 start-tag before the HTML preamble, rather than after the preamble
6685 but before the header file contents. [John Van Essen <jve@gamers.org>]
6688 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6689 only an issue on systems without a MAXDNAME define or where
6690 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6692 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6693 is used to read various types of files such as htaccess and
6694 htpasswd files. [Marc Slemko]
6696 *) SECURITY: Ensure that the buffer returned by ht_time is always
6697 properly null terminated. [Marc Slemko]
6699 *) The "Connection" header could be sent back with multiple "close"
6700 tokens. Not an error, but a waste.
6701 [Ronald.Tschalaer@psi.ch] PR#1683
6703 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
6704 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
6706 *) "basic" auth needs a case-insensitive comparison.
6707 [Ronald.Tschalaer@psi.ch] PR#1666
6709 *) For maximum portability, the environment passed to CGIs should
6710 only contain variables whose names match the regex
6711 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
6712 underscores over any character outside the regex. This
6713 affects HTTP_* variables, in a way that should be backward
6714 compatible for all the standard headers; and affects variables
6715 set with SetEnv/BrowserMatch and similar directives.
6718 *) mod_speling returned incorrect HREF's when an ambigous match

6754 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6755 including fixing a possible buffer overflow. [Dean Gaudet]
6757 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
6758 (connections are not dropped). Code can handle graceful restarts
6759 (but there is as yet no way to signal this to Apache). Various
6760 other cleanups. [Paul Sutton]
6762 *) The aplog_error changes specific to 1.3 introduced a buffer
6763 overrun in the (now legacy) log_printf function. Fixed.
6766 *) mod_digest didn't properly deal with proxy authentication. It
6767 also lacked a case-insensitive comparision of the "Digest"

6801 *) send_fd_length() did not calculate total_bytes_sent properly.
6802 [Ben Reser <breser@regnow.com>] PR#1366
6804 *) The bputc() macro was not properly integrated with the chunking
6805 code; in many cases modules using bputc() could cause completely
6806 bogus chunked output. (Typically this will show up as problems
6807 with Internet Explorer 4.0 reading a page, but other browsers
6808 having no problem.) [Dean Gaudet]
6810 *) Create LARGE_WRITE_THRESHOLD define which determines how many
6811 bytes have to be supplied to bwrite() before it will consider
6812 doing a writev() to assemble multiple buffers in one system
6813 call. This is critical for modules such as mod_include,
6814 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
6815 strings in some cases. The result would be extra effort
6816 setting up writev(), and in many cases extra effort building
6817 chunks. The default is 31, it can be overriden at compile

6927 This turns out to be a bug in Winsock - select() doesn't always
6928 return the correct status. [Ben Laurie]
6930 *) Directives owned by http_core can now use the new check_cmd_context()
6931 routine to ensure that they're not being used within a container
6932 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
6934 *) PORT: Recent changes made it necessary to add explicit prototype
6935 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
6937 *) It was necessary to distinguish between resources which are
6938 allocated in the parent, for cleanup in the parent, and resources
6939 which are allocated in each child, for cleanup in each child.
6940 A new pool was created which is passed to the module child_init
6941 and child_exit functions; modules are free to register per-child
6942 cleanups there. This fixes a bug with reliable piped logs.
6945 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
6946 unless it was also doing FancyIndexes, but it displayed the
6947 HeaderName file at the top under all circumstances. It now shows
6948 the ReadmeName file for simple indices, too, as it should.
6951 *) http_core was mmap()ing even in cases where it wasn't going to
6952 read the file. [Ben Hyde <bhyde@gensym.com>]
6954 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
6955 Now the rewriting engine (the heart of mod_rewrite) is organized more
6956 straight-forward, first time well documented and reduced to the really
6957 essential parts. All redundant cases were stripped off and processing now
6958 is the same for both per-server and per-directory context with only a
6959 minimum difference (the prefix stripping in per-dir context). As a
6960 side-effect some subtle restrictions and two recently discovered problems
6961 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
6962 context and restrictions on the substitution URL on redirects.
6963 Additionally some minor source cleanups were done.

6970 *) If ap_slack fails to allocate above the low slack line it's a good
6971 indication that further problems will occur; it's a better indication

7114 splits up a combined access log into separate files based on the
7115 name of the virtual host (listed first in the log records by "%v").
7118 Changes with Apache 1.3b2 (there is no 1.3b1)
7120 *) TestCompile was not passing $LIBS [Dean Gaudet]
7122 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7125 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7126 rudimentary memory debugger which can be used on live servers with
7127 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7128 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7129 and free() for each object. This is far more expensive and should
7130 only be used for testing with tools such as Electric Fence and
7131 Purify. See main/alloc.c for more details. [Dean Gaudet]
7133 *) Configure uses a sh trap and didn't set its exitcode properly.
7134 [Dean Gaudet] PR#1159
7136 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7137 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7138 From a given ip:port, regardless what the Host: header is, you can
7139 only reach the vhosts defined on that ip:port. The precedence of
7140 vhosts was reversed to match other precedences in the config --
7141 the earlier vhosts override the later vhosts. All vhost matching was
7142 moved into http_vhost.[ch]. [Dean Gaudet]
7144 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7145 be used for whatever reason is appropriate (i.e. format() warnings
7146 for printf style functions). Both are enabled only with
7147 gcc >= 2.7.x (so that we have fewer support issues with older
7148 versions). [Dean Gaudet]
7150 *) Fix support for Proxy Authentication (we were testing the response
7151 status too early). [Marc Slemko]
7153 *) CoreDumpDirectory directive directs where the core file is
7154 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7155 received. [Marc Slemko, Dean Gaudet]
7157 *) PORT: Support for Atari MINT.
7158 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7160 *) When booting, apache will now detach itself from stdin, stdout,
7161 and stderr. stderr will not be detached until after the config
7162 files have been read so you will be able to see initial error
7163 messages. After that all errors are logged in the error_log.
7164 This makes it more convenient to start apache via rsh, ssh,
7165 or crontabs. [Dean Gaudet] PR#523
7167 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7168 Also removed the auto-generated link to www.apache.org that was the
7169 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7171 *) send_fb would not detect aborted connections in some situations.
7174 *) mod_include would use uninitialized data when parsing certain
7175 expressions involving && and ||. [Brian Slesinsky] PR#1139
7177 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7179 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7181 *) mod_autoindex improperly counted &escapes; as more than one
7182 character in the description. It also improperly truncated
7183 descriptions that were exactly the maximum length.
7186 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7187 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7190 *) mod_include now uses symbolic names to check for request success
7191 and return HTTP errors, and correctly handles all types of
7192 redirections (previously it only did temporary redirect correctly).
7193 [Ken Coar, Roy Fielding]
7195 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7196 r->filename. Since those two are meant to be in sync with each other
7197 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7199 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7200 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]

7203 jmpbuffer. [Dean Gaudet] PR#1064

7206 reporting a select error over and over.
7207 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7209 *) Fixed error in proxy_util.c when looping through multiple host IP
7210 addresses. [Lars Eilebrecht] PR#974
7212 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7213 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7214 bytes before writing, but it will never split a log entry across a
7215 buffer boundary. [Dean Gaudet]
7217 *) API: the short_score record has been split into two pieces, one which
7218 the parent writes on, and one which the child writes on. As part of
7219 this change the get_scoreboard_info() function was removed, and
7220 scoreboard_image was exported. This change fixes a race condition
7221 in file based scoreboard systems, and speeds up changes involving the
7222 scoreboard in earlier 1.3 development. [Dean Gaudet]
7224 *) API: New register_other_child() API (see http_main.h) which allows
7225 modules to register children with the parent for maintenance. It
7226 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7228 *) API: New piped_log API (see http_log.h) which implements piped logs,
7229 and will use register_other_child to implement reliable piped logs
7230 when it is available. The reliable piped logs part can be disabled
7231 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7232 logs is only available on Unix. [Dean Gaudet]
7234 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7235 meets_conditions(). This allows conditional HTTP selection to be
7236 handled separately from the storing of the header fields, and provides
7237 the ability for CGIs to set their own ETags for conditional checking.
7238 [Ken Coar, Roy Fielding] PR#895
7240 *) Changes to mod_log_config to allow naming of format strings.
7241 Format nicknames are defined with "LogFormat fmt nickname", and can
7242 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7245 *) New module, "mod_speling", which can help find files even when
7246 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7248 *) API: New function child_terminate() triggers the child process to
7249 exit, while allowing the child finish what it needs to for the
7250 current request first.
7251 [Doug MacEachern, Alexei Kosut]
7253 *) Windows now defaults to using full status reports with mod_status.
7254 [Alexei Kosut] PR #1094
7256 *) *Really* disable all mod_rewrite operations if the engine is off.
7257 Some things (like RewriteMaps) were checked/performed even if they
7258 weren't supposed to be. [Ken Coar] PR #991
7260 *) Implement a new timer scheme which eliminates the need to call alarm() all
7261 the time. Instead a counter in the scoreboard for each child is used to
7262 show when the child has made forward progress. The parent samples this
7263 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7264 progress has been made in the timeout period. This reduces the static
7265 request best-case syscall count to 22 from 29. This scheme is only
7266 used by systems with memory-based scoreboards. [Dean Gaudet]
7268 *) The proxy now properly handles CONNECT requests which are sent
7269 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7271 *) A script called apachectl has been added to the support
7272 directory. This script allows you to do things such as
7273 "apachectl start" and "apachectl restart" from the command
7276 *) Modules and core routines are now put into libraries, which
7277 simplifies the link line tremendously (among other advantages).
7280 *) Some of the MD5 names defined in Apache have been renamed to have
7281 an `ap_' prefix to avoid conflicts with routines supplied by
7282 external libraries. [Ken Coar]
7284 *) Removal of mod_auth_msql.c from the distribution. There are many
7285 other options for databases today. Rather than offer one option,
7286 offer none at this time. mod_auth_msql and other SQL database
7287 authentication modules can be found at the Apache Module Registry.
7288 http://modules.apache.org/ It would be nice to offer a generic
7289 mod_auth_sql option in the near future.
7291 *) PORT: BeOS support added [Alexei Kosut]
7293 *) Configure no longer accepts the -make option, since it creates
7294 Makefile on the fly based on Makefile.tmpl and Configuration.
7296 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7297 of forcibly killing off all its processes and exiting without
7298 cleaning up. [Alexei Kosut]
7300 *) API: A new field in the request_rec, r->mtime, has been added to
7301 avoid gratuitous parsing of date strings. It is intended to hold
7302 the last-modified date of the resource (if applicable). An
7303 update_mtime() routine has also been added to advance it if
7304 appropriate. [Roy Fielding, Ken Coar]
7306 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7307 deny access to the directory with a HTTP_FORBIDDEN. The previous
7308 behavior was to ignore the htaccess file if it could not be read.
7309 This change may make some setups with unreadable htaccess files
7310 stop working. [Marc Slemko] PR#817
7312 *) Add aplog_error() providing a mechanism to define levels of
7313 verbosity to the server error logging. This addition also provides
7314 the ability to log errors using syslogd. Error logging is configurable
7315 on a per-server basis using the LogLevel directive. Conversion
7316 of log_*() in progress. [Randy Terbush]
7318 *) Further enhance aplog_error() to not log filename, line number, and
7319 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7321 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7322 converted to long ones. Backslashes are converted to forward
7323 slashes. Case is converted to lower. Parts of URLs that do not
7324 correspond to files are left completely alone. [Ben Laurie]
7326 *) PORT: 2 new OSs added to the list of ports:
7327 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7328 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7330 *) Add the server version (SERVER_VERSION macro) to the "server
7331 configured and running" entry in the error_log. Also build an
7332 object file at link-time that contains the current time
7333 (SERVER_BUILT global const char[]), and include that in the
7336 *) Set r->headers_out when sending responses from the proxy.
7337 This fixes things such as the logging of headers sent from
7338 the proxy. [Marc Slemko] PR#659
7340 *) support/httpd_monitor is no longer distributed because the
7341 scoreboard should not be file based if at all possible. Use
7342 mod_status to see current server snapshot.
7344 *) (set_file_slot): New function, allowing auth directives to be
7345 independent of the server root, so the server documents can be
7346 moved to a different directory or machine more easily.
7347 [David J. MacKenzie]
7349 *) If no TransferLog is given explicitly, decline
7350 to log. This supports coexistence with other logging modules,
7351 such as the custom one that UUNET uses. [David J. MacKenzie]
7353 *) Check for titles in server-parsed HTML files.
7354 Ignore leading newlines and returns in titles. The old behavior
7355 of replacing a newline after <title> with a space causes the
7356 title to be misaligned in the listing. [David J. MacKenzie]
7358 *) Change mod_cern_meta to be configurable on a per-directory basis.
7359 [David J. MacKenzie]
7361 *) Add 'Include' directive to allow inclusion of configuration
7362 files within configuration files. [Randy Terbush]
7364 *) Proxy errors on connect() are logged to the error_log (nothing
7365 new); now they include the IP address and port that failed
7366 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7368 *) Various architectures now define USE_MMAP_FILES which causes
7369 the server to use mmap() for static files. There are two
7370 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7371 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7372 number of bytes written in one cycle from a single mmap()d object,
7373 default 32768). [Dean Gaudet]
7375 *) API: Added post_read_request API phase which is run right after reading
7376 the request from a client, or right after an internal redirect. It is
7377 useful for modules setting environment variables that depend only on
7378 the headers/contents of the request. It does not run during subrequests
7379 because subrequests inherit pretty much everything from the main
7380 request. [Dean Gaudet]
7382 *) Added mod_unique_id which is used to generate a unique identifier for
7383 each hit, available in the environment variable UNIQUE_ID.
7386 *) init_modules is now called after the error logs have been opened. This
7387 allows modules to emit information messages into the error logs.
7390 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7391 information for case where proxy module is not available. [Marc Slemko]
7393 *) PORT: Apache has need for mutexes to serialize its children around
7394 accept. In prior versions either fcntl file locking or flock file
7395 locking were used. The method is chosen by the definition of
7396 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7397 and FLOCK for flock(). New options have been added:
7398 - SYSVSEM to use System V style semaphores
7399 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7400 - USLOCK to use IRIX uslock
7401 Based on timing various techniques, the following changes were made
7403 - Linux 2.x uses flock instead of fcntl
7404 - Solaris 2.x uses pthreads
7405 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7406 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7407 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7408 Martijn Koster <m.koster@pobox.com>]
7410 *) PORT: The semantics of accept/select make it very desirable to use
7411 mutexes to serialize accept when multiple Listens are in use. But
7412 in the case where only a single socket is open it is sometimes
7413 redundant to serialize accept(). Not all unixes do a good job with
7414 potentially dozens of children blocked on accept() on the same
7415 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7416 the server will avoid serialization when listening on only one socket,
7417 and use serialization when listening on multiple sockets.
7418 [Dean Gaudet] PR#467
7420 *) Configure changes: TestLib replaced by TestCompile, which has
7421 some additional capability (such as doing a sanity check of
7422 the compiler and flags selected); the version of Solaris is now
7423 available via the #define value of SOLARIS2; IRIX n32bit libs
7424 now supported and selectable by new Configuration Rule: IRIXN32;
7425 We no longer default to -O2 optimization. [Jim Jagielski]
7427 *) Updated Configure: Configuration now uses AddModule to specify
7428 module source or binary file location, relative to src directory.
7429 Modules can be dropped into modules/extra, or in their own
7430 directory, and modules can come with a Makefile or Configure can
7431 create one. Modules can add compiler or library information to
7432 generated Makefiles. [Paul Sutton]
7434 *) Source core re-organisation: distributed modules are now in
7435 modules/standard. All other source code is in main. OS-specific
7436 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7438 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7441 *) Fix another long-standing bug in sub_req_lookup_file where it would
7442 happily skip past access checks on subdirectories looked up with
7443 relative paths. (It's used by mod_dir, mod_negotiation,
7444 and mod_include.) [Dean Gaudet]
7446 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7447 N is the number of <Directory> sections, and M is the number of
7448 components in the filename of an object.
7450 To achieve this optimization the following config changes were made:
7451 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7452 <Files>s, and <Location>s now treat a slash as a special
7453 character. For example "/home/*/public_html" previously would
7454 match "/home/a/andrew/public_html", now it only matches things
7455 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7456 - It's possible now to use [] wildcarding in <Directory>, <Files>
7458 - Regex <Directory>s are applied after all non-regex <Directory>s.
7462 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7463 and corrupted paths. [Dean Gaudet]
7465 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7466 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7467 be accessed now via backreferences $1..$9 in RewriteConds test-against
7468 strings in addition to RewriteRules subst string. Second the grouped
7469 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7470 via backreferences %1..%9 both in following RewriteCond test-against
7471 strings and RewriteRules subst string. This provides maximum flexibility
7472 through the use of backreferences.
7473 Additionally the rewriting engine was cleaned up by putting common
7474 code to the new expand_backrefs_inbuffer() function.
7475 [Ralf S. Engelschall]
7477 *) When merging the main server's <Directory> and <Location> sections into
7478 a vhost, put the main server's first and the vhost's second. Otherwise
7479 the vhost can't override the main server. [Dean Gaudet] PR#717
7481 *) The <Directory> code would merge and re-merge the same section after
7482 a match was found, possibly causing problems with some modules.
7485 *) ip-based vhosts are stored and queried using a hashing function, which
7486 has been shown to improve performance on servers with many ip-vhosts.
7487 Some other changes had to be made to accommodate this:
7488 - the * address for vhosts now behaves like _default_
7489 - the matching process now is:
7490 - match an ip-vhost directly via hash (possibly matches main
7492 - if that fails, just pretend it matched the main server
7493 - if so far only the main server has been matched, perform
7494 name-based lookups (ServerName, ServerAlias, ServerPath)
7495 *only on name-based vhosts*
7496 - if they fail, look for _default_ vhosts
7497 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7499 *) dbmmanage overhaul:
7500 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7501 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7502 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7503 - provide better seed for rand
7504 - prompt for password as per getpass(3) (turn off echo, read from
7506 - use "newstyle" crypt based on $Config{osname} ($^O)
7507 - will not add a user if already in database, use new `update' command
7509 - added `check' command to check a users' password
7510 - added `import' command to convert existing password text-files or
7511 dbm files exported with `view'
7512 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7515 *) Added psocket() which is a pool form of socket(), various places within
7516 the proxy weren't properly blocking alarms while registering the cleanup
7517 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7518 was a bug where the client socket was being close()d twice due a still
7519 registered cleanup. [Dean Gaudet]
7521 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7524 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7525 [Jason Venner <jason@idiom.com>] PR#667
7527 *) Enable ``=""'' for RewriteCond directives to match against
7528 the empty string. This is the preferred way instead of ``^$''.
7529 [Ralf S. Engelschall]
7531 *) Fixed an infinite loop in mod_imap for references above the server root
7532 [Dean Gaudet] PR#748
7534 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7535 SendBufferSize, so that the TCP window can be set appropriately
7536 for LFNs. [Phillip A. Prindeville]
7538 *) mod_browser has been replaced by the more general mod_setenvif
7539 (courtesy of Paul Sutton). BrowserMatch* directives are still
7540 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7541 UnSetEnvIfZero directives. [Ken Coar]
7543 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7544 order for remote_host to be set (for logging, or for the env var
7545 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7548 *) mod_access overhaul:
7549 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7550 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7551 - Critical path was sped up by pre-computing a few things at config time.
7552 - The undocumented syntax "allow user-agents" was removed,
7553 the replacement is "allow from env=foobar" combined with mod_browser.
7554 - When used with hostnames it now forces a double-reverse lookup
7555 no matter what the directory settings are. This double-reverse
7556 doesn't affect any of the other routines that use the remote
7557 hostname. In particular it's still passed to CGIs and the log
7558 without the double-reverse check. Related PR#860.
7561 *) When a large bwrite() occurs (larger than the internal buffer size),
7562 while there is already something in the buffer, apache will combine
7563 the large write and the buffer into a single writev(). (This is
7564 in anticipation of using mmap() for reading files.)
7567 *) In obscure cases where a partial socket write occurred while chunking,
7568 Apache would omit the chunk header/footer on the next block. Cleaned
7569 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7570 a bug where a long pause in DNS lookups could cause the last packet
7571 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7573 *) API: Added child_exit function to module structure. This is called
7574 once per "heavy-weight process" just before a server child exit()'s
7575 e.g. when max_requests_per_child is reached, etc.
7576 [Doug MacEachern, Dean Gaudet]
7578 *) mod_include cleanup showed that handle_else was being used to handle
7579 endif. It didn't cause problems, but it was cleaned up too.
7582 *) mod_cern_meta would attempt to find meta files for the directory itself
7583 in some cases, but not in others. It now avoids it in all cases.
7586 *) mod_mime_magic would core dump if there was a decompression error.
7587 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7589 *) PORT: some variants of DGUX require -lsocket -lnsl
7590 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7592 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7593 by the various fields (name, size, et cetera), either in ascending
7594 or descending order. Just click on the column header. [Ken Coar]
7596 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7597 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7598 the relatively safe direction. [Dean Gaudet] PR#344
7600 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7601 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7603 *) child_main avoids an unneeded call to select() when there is only one
7604 listening socket. [Dean Gaudet]
7606 *) In the event that the server is starved for idle servers it will
7607 spawn 1, then 2, then 4, ..., then 32 servers each second,
7608 doubling each second. It'll also give a warning in the errorlog
7609 since the most common reason for this is a poor StartServers
7610 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7611 the maximum. [Dean Gaudet]
7613 *) Apache now provides an effectively unbuffered connection for
7614 CGI scripts. This means that data will be sent to the client
7615 as soon as the CGI pauses or stops output; previously, Apache would
7616 buffer the output up to a fixed buffer size before sending, which
7617 could result in the user viewing an empty page until the CGI finished
7618 or output a complete buffer. It is no longer necessary to use an
7619 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7620 in a language that by default does buffering (e.g. perl) this
7621 shouldn't have a detrimental effect on performance.
7623 "nph-" CGIs, which formerly provided a direct socket to the client
7624 without any server post-processing, were not fully compatible with
7625 HTTP/1.1 or SSL support. As such they would have had to implement
7626 the transport details, such as encryption or chunking, in order
7627 to work properly in certain situations. Now, the only difference
7628 between nph and non-nph scripts is "non-parsed headers".
7629 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7631 *) If a BUFF is switched from buffered to unbuffered reading the first
7632 bread() will return whatever remained in the buffer prior to the
7633 switch. [Dean Gaudet]
7635 Changes with Apache 1.3a1
7637 *) Added another Configure helper script: TestLib. It determines
7638 if a specified library exists. [Jim Jagielski]
7640 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7641 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7644 *) PORT: Some architectures use size_t for various lengths in network
7645 functions such as accept(), and getsockname(). The definition
7646 NET_SIZE_T is used to control this. [Dean Gaudet]
7648 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7649 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7650 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7652 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7653 [Igor N Kovalenko <infoh@mail.wplus.net>]
7655 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7656 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7657 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7658 [Dean Gaudet] related PR#875
7660 *) API: Correct child_init() slot declaration from int to void, to
7661 match the init() declaration. Update mod_example to use the new
7664 *) added transport handle slot (t_handle) to the BUFF structure
7667 *) get_client_block() returns wrong length if policy is
7668 REQUEST_CHUNKED_DECHUNK.

7678 *) AddModuleInfo directive for mod_info which allows you to annotate
7679 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7681 *) Added NoProxy directive to avoid using ProxyRemote for selected
7682 addresses. Added ProxyDomain directive to cause unqualified
7683 names to be qualified by redirection.
7684 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7686 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7687 header to the remote host in the proxy. [Sameer Parekh and
7690 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7691 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7692 URLs, fixed rewritelog(), fixed forced response code handling on
7693 redirects from within .htaccess files, disabled pipe locking under
7694 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7695 no substitution, bugfixed situations where HostnameLookups is off, made
7696 mod_rewrite more thread-safe for NT port and fixed problem when creating
7697 an empty query string via "xxx?".
7698 This update also removes the copyright of Ralf S. Engelschall,
7699 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7700 exclusively copyrighted by the Apache Group now. This happened because
7701 the author now has gifted mod_rewrite exclusively to the Apache Group and
7702 no longer maintains an external version.
7703 [Ralf S. Engelschall]
7705 *) API: Added child_init function to module structure. This is called
7706 once per "heavy-weight process" before any requests are handled.
7707 See http_config.h for more details. [Dean Gaudet]
7709 *) Anonymous_LogEmail was logging on each subrequest.
7710 [Dean Gaudet] PR#421, 868
7712 *) API: Added is_initial_req() which tests if the request being
7713 processed is the initial request, or a subrequest.
7716 *) Extended SSI (mod_include) now handles additional relops for
7717 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7719 *) Configure fixed to correctly propagate user-selected options and
7720 settings (such as CC and OPTIM) to Makefiles other than
7721 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7723 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7724 directory indices to start with the contents of the HeaderName file
7725 if there is one. If there isn't one, the behaviour is unchanged.
7726 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7728 *) WIN32: Modules can now be dynamically loaded DLLs using the
7729 LoadModule/LoadFile directives. Note that module DLLs must be
7730 compiled with the multithreaded DLL version of the runtime library.
7731 [Alexei Kosut and Ben Laurie]
7733 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7734 This allows the admin to completely remove automatic indexing
7735 from the server, while still supporting the basic functions of
7736 trailing-slash redirects and DirectoryIndex files. Note that if
7737 you're carrying over an old Configuration file and you use directory
7738 indexing then you'll want to add:
7740 Module autoindex_module mod_autoindex.o
7742 before mod_dir in your Configuration. [Dean Gaudet]
7744 *) popendir/pclosedir created to properly protect directory scanning.
7745 [Dean Gaudet] PR#525
7747 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7748 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>

7756 of a file if the extension is unknown. Based on the unix file(1)
7757 command. [Ian Kluft <ikluft@cisco.com>]
7759 *) We now determine and display the time spent processing a
7760 request if desired. [Jim Jagielski]
7762 *) mod_status: PID field of "dead" child slots no longer displays
7763 main httpd process's PID. [Jim Jagielski]
7765 *) Makefile.nt added - to build all the bits from the command line:
7766 nmake -f Makefile.nt
7767 Doesn't yet work properly. [Ben Laurie]
7769 *) Default text of 404 error is now "Not Found" rather than the
7770 potentially misleading "File Not Found". [Ken Coar]
7772 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7773 for the net if we require people that actually need this data to
7774 enable it. [Linus Torvalds]
7776 *) directory_walk() is an expensive function, keep a little more state to
7777 avoid needless string counting. Add two new functions make_dirstr_parent
7778 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7779 The new functions are a little less general than make_dirstr, but
7780 work more efficiently (less memory, less string counting).
7783 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7784 to LDFLAGS) to avoid complications with lex rules in make files.
7785 [Dean Gaudet] PR#372
7787 *) run_method optimized to avoid needless scanning over NULLs in the
7788 module list. [Dean Gaudet]
7790 *) Revamp of (unix) scoreboard management code such that it avoids
7791 unnecessary traversals of the scoreboard on each hit. This is
7792 particularly important for high volume sites with a large
7793 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7794 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7795 httpd.h. [Dean Gaudet]
7797 *) In configurations using multiple Listen statements it was possible for
7798 busy sockets to starve other sockets of service. [Dean Gaudet]
7800 *) Added hook so standalone_main can be replaced at compile time
7801 (define STANDALONE_MAIN)
7804 *) Lowest-level read/write functions in buff.c will be replaced with
7805 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7806 compile time. The default sfio discipline will behave as apache
7807 would without sfio compiled in.
7810 *) Enhance UserDir directive (mod_userdir) to accept a list of
7811 usernames for the 'disable' keyword, and add 'enable user...' to
7812 selectively *en*able userdirs if they're globally disabled.
7815 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7816 will work with Netscape dbm files. (dbmmanage will probably not
7817 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7819 *) Add a ListenBacklog directive to control the backlog parameter
7820 passed to listen(). Also change the default to 511 from 512.
7823 *) API: A new handler response DONE which informs apache that the
7824 request has been handled and it can finish off quickly, similar to
7825 how it handles errors. [Rob Hartill]
7827 *) Turn off chunked encoding after sending terminating chunk/footer
7828 so that we can't do it twice by accident. [Roy Fielding]
7830 *) mod_expire also issues Cache-Control: max-age headers.
7833 *) API: Added kill_only_once option for free_proc_chain so that it won't
7834 aggressively try to kill off specific children. For fastcgi.
7835 [Stanley Gambarin <gambarin@OpenMarket.com>]
7837 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7839 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7840 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7841 attributes in the FancyIndexing IMG tags. [Ken Coar]
7843 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7845 *) PORT: Added Windows NT support

7877 *) When an error occurs in fcntl() locking suggest the user look up
7878 the docs for LockFile. [Dean Gaudet]
7880 *) table_set() and table_unset() did not deal correctly with

7890 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7891 Also removed the auto-generated link to www.apache.org that was the
7892 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7894 *) Multiple "close" tokens may have been set in the "Connection"
7895 header, not an error, but a waste.
7896 [Ronald.Tschalaer@psi.ch] PR#1683
7898 *) "basic" and "digest" auth tokens should be tested case-insensitive.

7901 *) It appears the "257th byte" bug (see
7902 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7903 at the 256th byte as well. Fixed. [Dean Gaudet]
7905 *) mod_rewrite would not handle %3f properly in some situations.
7908 *) Apache could generate improperly chunked HTTP/1.1 responses when
7909 the bputc() or rputc() functions were used by modules (such as
7910 mod_include). [Dean Gaudet]
7912 *) #ifdef wrap a few #defines in httpd.h to make life easier on

7915 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7917 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7919 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7921 Changes with Apache 1.2.5
7923 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7924 only an issue on systems without a MAXDNAME define or where
7925 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7927 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7930 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7931 directory listings. [Marc Slemko]
7933 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7936 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7937 is used to read various types of files such as htaccess and
7938 htpasswd files. [Marc Slemko]
7940 *) SECURITY: Ensure that the buffer returned by ht_time is always
7941 properly null terminated. [Marc Slemko]
7943 *) SECURITY: General mod_include cleanup, including fixing several
7944 possible buffer overflows and a possible infinite loop. This cleanup
7945 was done against 1.3 code and then backported to 1.2, the result
7946 is a large difference (due to indentation cleanup in 1.3 code).
7947 Users interested in seeing a smaller set of relevant differences
7948 should consider comparing against src/modules/standard/mod_include.c
7949 from the 1.3b3 release. Non-indentation changes to mod_include
7950 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7952 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7953 including fixing a possible buffer overflow. This cleanup also
7954 was done with 1.3 code as a basis, see the the previous note
7955 about mod_include. [Dean Gaudet]
7957 *) SECURITY: If a htaccess file can not be read due to bad
7958 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7959 The previous behavior was to ignore the htaccess file if it could not
7960 be read. This change may make some setups with unreadable
7961 htaccess files stop working. PR#817 [Marc Slemko]
7963 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7964 Make it O(n). This inefficiency could be used to mount a denial

7973 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7975 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7977 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7978 r->filename. Since those two are meant to be in sync with each other
7979 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

7991 Changes with Apache 1.2.4
7993 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7994 always making requests with the full-URI instead of just the URI path.
7995 [Marc Slemko, Roy Fielding]
7997 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7998 on this platform. [Marc Slemko]
8000 Changes with Apache 1.2.3
8002 *) The request to a remote proxy was mangled if it was generated as the
8003 result of a ProxyPass directive. URL schemes other than http:// were not
8004 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
8005 PR#812 [Lars Eilebrecht]
8007 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
8008 information for case where proxy module is not available. [Marc Slemko]
8010 *) Force proxy to always respond as HTTP/1.0, which it was failing to
8011 do for errors and cached responses. [Roy Fielding]
8013 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
8015 Changes with Apache 1.2.2 [not released]
8017 *) Fixed another long-standing bug in sub_req_lookup_file where it would
8018 happily skip past access checks on subdirectories looked up with relative
8019 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
8022 *) Add lockfile name to error message printed out when
8023 USE_FLOCK_SERIALIZED_ACCEPT is defined.
8026 *) Enhanced the chunking and error handling inside the buffer functions.
8027 [Dean Gaudet, Roy Fielding]
8029 *) When merging the main server's <Directory> and <Location> sections into
8030 a vhost, put the main server's first and the vhost's second. Otherwise
8031 the vhost can't override the main server. [Dean Gaudet] PR#717
8033 *) The <Directory> code would merge and re-merge the same section after
8034 a match was found, possibly causing problems with some modules.
8037 *) Fixed an infinite loop in mod_imap for references above the server root.
8038 [Dean Gaudet] PR#748
8040 *) mod_include cleanup showed that handle_else was being used to handle
8041 endif. It didn't cause problems, but it was cleaned up too.
8044 *) Last official synchronization of mod_rewrite with author version (because
8045 mod_rewrite is now directly developed by the author at the Apache Group):
8046 o added diff between mod_rewrite 3.0.6+ and 3.0.9
8047 minus WIN32/NT stuff, but plus copyright removement.
8049 - workaround for detecting infinite rewriting loops
8050 - fixed setting of env vars when "-" is used as subst string
8051 - fixed forced response code on redirects (PR#777)
8052 - fixed cases where r->args is ""
8053 - kludge to disable locking on pipes under braindead SunOS
8054 - fix for rewritelog in cases where remote hostname is unknown
8055 - fixed totally damaged request_rec walk-back loop
8056 o remove static from local data and add static to global ones.
8057 o replaced ugly proxy finding stuff by simple
8058 find_linked_module("mod_proxy") call.
8059 o added missing negation char on rewritelog()
8060 o fixed a few comment typos
8061 [Ralf S. Engelschall]
8063 *) Anonymous_LogEmail was logging on each subrequest.
8064 [Dean Gaudet] PR#421, PR#868
8066 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
8067 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8068 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
8069 Additionally mod_browser now triggers during translate_name to workaround
8070 a deficiency in the header_parse phase.

8077 *) Properly treat <files> container like other containers in mod_info.
8078 [Marc Slemko] PR#848
8080 *) The proxy didn't treat the "Host:" keyword of the host header as case-
8081 insensitive. The proxy would corrupt the first line of a response from
8082 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
8084 *) mod_include would log some bogus values occasionally.

8087 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
8088 under Solaris 2.x (up through 2.5.1). It has been fixed.
8089 [Dean Gaudet] PR#832
8091 *) API: In HTTP/1.1, whether or not a request message contains a body
8092 is independent of the request method and based solely on the presence
8093 of a Content-Length or Transfer-Encoding. Therefore, our default
8094 handlers need to be prepared to read a body even if they don't know
8095 what to do with it; otherwise, the body would be mistaken for the
8096 next request on a persistent connection. discard_request_body()
8097 has been added to take care of that. [Roy Fielding] PR#378
8099 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
8100 release version number, such that it always increases along the
8101 same lines as our source code branching. [Roy Fielding]
8103 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
8105 Changes with Apache 1.2.1
8107 *) SECURITY: Don't serve file system objects unless they are plain files,
8108 symlinks, or directories. This prevents local users from using pipes
8109 or named sockets to invoke programs for an extremely crude form of

8113 could contain "../" allowing a local user to "publish" any file on
8114 the system. No slashes are allowed now. [Dean Gaudet]
8116 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8117 (headers, readmes, titles), mod_negotiation (type maps), or
8118 mod_cern_meta (meta files). [Dean Gaudet]
8120 *) SECURITY: Apache will refuse to run as "User root" unless
8121 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8123 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8124 if it contained a .htaccess disallowing symlinks. This is contrary
8125 to the rule that symlink permissions are tested with the symlink
8126 options of the parent directory. [Dean Gaudet] PR#353
8128 *) CONFIG: The LockFile directive can be used to place the serializing
8129 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8130 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8133 *) Request processing now retains state of whether or not the request
8134 body has been read, so that internal redirects and subrequests will
8135 not try to read it twice (and block). [Roy Fielding]
8137 *) Add a placeholder in modules/Makefile to avoid errors with certain
8138 makes. [Marc Slemko]
8140 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

8146 *) Attempt to work around problems with third party libraries that do not
8147 handle high numbered descriptors (examples include bind, and
8148 solaris libc). On all systems apache attempts to keep all permanent
8149 descriptors above 15 (called the low slack line). Solaris users
8150 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8151 which keeps all non-FILE * descriptors above 255. On all systems
8152 this should make supporting large numbers of vhosts with many open
8153 log files more feasible. If this causes trouble please report it,
8154 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8155 [Dean Gaudet] various PRs
8157 *) Related to the last entry, network sockets are now opened before
8158 log files are opened. The only known case where this can cause
8159 problems is under Solaris with many virtualhosts and many Listen
8160 directives. But using -DHIGH_SLACK_LINE=256 described above will
8161 work around this problem. [Dean Gaudet]
8163 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8166 *) Improved unix error response logging. [Marc Slemko]
8168 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8169 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8170 when a URL http://... was used in conjunction with a special
8171 redirect flag, e.g. R=permanent, the permanent status was lost.

8206 Changes with Apache 1.2
8208 Changes with Apache 1.2b11
8210 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
8212 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
8213 [Doug MacEachern, Rob Hartill]
8215 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
8216 reading from one buffer and writing to another, at least until it has
8217 a custom timeout handler. [Roy Fielding and Petr Lampa]
8219 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
8220 apparently due to a mismatch between sigaction and setjmp.
8221 [Roy Fielding] PR#502
8223 *) Log correct status code if we timeout before receiving a request (408)
8224 or if we received a request-line that was too long to process (414).
8225 [Ed Korthof and Roy Fielding] PR#601
8227 *) Virtual hosts with the same ServerName, but on different ports, were
8228 not being selected properly. [Ed Korthof]
8230 *) Added code to return the requested IP address from proxy_host2addr()
8231 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
8232 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8233 [Chuck Murcko] PR#614
8235 *) If multiple requests on a single connection are used to retrieve
8236 data from different virtual hosts, the virtual host list would be
8237 scanned starting with the most recently used VH instead of the first,
8238 causing most virtual hosts to be ignored.
8239 [Paul Sutton and Martin Mares] PR#610
8241 *) The OS/2 handling of process group was broken by a porting patch for
8242 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
8244 *) Inherit virtual server port from main server if none (or "*") is
8245 given for VirtualHost. [Dean Gaudet] PR#576
8247 *) If the lookup for a DirectoryIndex name with content negotiation
8248 has found matching variants, but none are acceptable, return the
8249 negotiation result if there are no more DirectoryIndex names to lookup.
8250 [Petr Lampa and Roy Fielding]
8252 *) If a soft_timeout occurs after keepalive is set, then the main child
8253 loop would try to read another request even though the connection
8254 has been aborted. [Roy Fielding]
8256 *) Configure changes: Allow for whitespace at the start of a
8257 Module declaration. Also, be more understanding about the
8258 CC=/OPTIM= format in Configuration. Finally, fix compiler
8259 flags if using HP-UX's cc compiler. [Jim Jagielski]
8261 *) Subrequests and internal redirects now inherit the_request from the
8262 original request-line. [Roy Fielding]
8264 *) Test for error conditions before creating output header fields, since
8265 we don't want the error message to include those fields. Likewise,
8266 reset the content_language(s) and content_encoding of the response
8267 before generating or redirecting to an error message, since the new
8268 message will have its own Content-* definitions. [Dean Gaudet]
8270 *) Restored the semantics of headers_out (headers sent only with 200..299
8271 and 304 responses) and err_headers_out (headers sent with all responses).
8272 Avoid the overhead of copying tables if err_headers_out is empty
8273 (the usual case). [Roy Fielding]
8275 *) Fixed a couple places where a check for the default Content-Type was
8276 not properly checking both the value configured by the DefaultType
8277 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8278 of DEFAULT_TYPE to match the documented default (text/plain).

8281 *) Escape the HTML-sensitive characters in the Request-URI that is
8282 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8284 *) Properly initialize the flock structures used by the mutex locking
8285 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8288 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8289 (and NCSA httpd) definition wherein it was the extra path info beyond
8290 the CGI script filename. The environment variable FILEPATH_INFO has
8291 been removed, and instead we supply the original REQUEST_URI to any
8292 script that wants to be Apache-specific and needs the real URI path.
8293 This solves a problem with existing scripts that use extra path info
8294 in the ScriptAlias directive to pass options to the CGI script.
8297 *) The _default_ change in 1.2b10 will change the behaviour on configs
8298 that use multiple Listen statements for listening on multiple ports.
8299 But that change is necessary to make _default_ consistent with other
8300 forms of <VirtualHost>. It requires such configs to be modified
8301 to use <VirtualHost _default_:*>. The documentation has been
8302 updated. [Dean Gaudet] PR#530
8304 *) If an ErrorDocument CGI script is used to respond to an error
8305 generated by another CGI script which has already read the message
8306 body of the request, the server would block trying to read the
8307 message body again. [Rob Hartill]
8309 *) signal() replacement conflicted with a define on QNX (and potentially
8310 other platforms). Fixed. [Ben Laurie] PR#512
8312 Changes with Apache 1.2b10

8326 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8328 Changes with Apache 1.2b9 [never announced]
8330 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8331 changes and in anticipation of 1.2 final release. [Roy Fielding]
8333 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8334 the connection (e.g., when user presses Stop). Apache will now stop
8335 trying to send a message body immediately after an error from write.
8336 [Roy Fielding and Nathan Kurz] PR#335
8338 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8339 than mod_alias, and mod_alias has higher priority than mod_proxy;
8340 rearranged other modules to enhance understanding of their purpose
8341 and relative order (and maybe even reduce some overhead).
8342 [Roy Fielding and Sameer Parekh]
8344 *) Fix graceful restart. Eliminate many signal-related race
8345 conditions in both forms of restart, and in SIGTERM. See
8346 htdocs/manual/stopping.html for details on stopping and
8347 restarting the parent. [Dean Gaudet]
8349 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8350 memory allocator to avoid a behaviour that required extra blocks to
8351 be allocated. [Dean Gaudet]
8353 *) Allow suexec to access files relative to current directory but not
8354 above. (Excluding leading / or any .. directory.) [Ken Coar]
8357 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8358 PR#367, 368, 354, 453
8360 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8361 while obtaining the /~user and save the username in a separate data
8362 area so that it won't be overwritten by the call to getgrgid(), and
8363 fix some misuse of the pool string allocation functions. Also fixes
8364 a general problem with parsing URL query info into args for CGI scripts.

8372 AuthDBAuthoritative. [Marc Slemko] PR#420
8374 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375

8377 object that can't be PUT, or FOOBAR for some method FOOBAR that
8378 apache doesn't know about at all). Log 404s that occur in mod_include.
8379 [Paul Sutton, John Van Essen]
8381 *) If a soft timeout (or lingerout) occurs while trying to flush a
8382 buffer or write inside buff.c or fread'ing from a CGI's output,
8383 then the timeout would be ignored. [Roy Fielding] PR#373
8385 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8386 parsing of headers. If the terminating empty-line CRLF occurs starting
8387 at the 256th or 257th byte of output, then Navigator will think a normal
8388 image is invalid. We are guessing that this is because their initial
8389 read of a new request uses a 256 byte buffer. We check the bytes written
8390 so far and, if we are about to tickle the bug, we instead insert a
8391 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232

8394 of an external redirection. [Roy Fielding and Paul Sutton]
8396 *) Configure would create a broken Makefile if the configuration file
8397 contained a commented-out Rule. [Roy Fielding]
8399 *) Promote per_dir_config and subprocess_env from the subrequest to the
8400 main request in mod_negotiation. In particular this fixes a bug
8401 where <Files> sections wouldn't properly apply to negotiated content.
8404 *) Fix a potential deadlock in mod_cgi script_err handling.
8405 [Ralf S. Engelschall]
8407 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8410 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8411 .htaccess files because the RewriteBase was not replaced correctly.
8412 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8413 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8415 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8416 1.x the settings are those of pre-1.2b8. For 2.x we include
8417 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8418 HAVE_SYS_RESOURCE_H (enable the RLimit commands).

8426 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8428 *) Add UnixWare compile/install instructions. [Chuck Murcko]

8437 *) For hosts with multiple IP addresses, try all additional addresses if
8438 necessary to get a connect. Fail only if hostent address list is
8439 exhausted. [Chuck Murcko]
8441 *) More signed/unsigned port fixes. [Dean Gaudet]
8443 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8446 Changes with Apache 1.2b8
8448 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8449 to it. [Marc Slemko]
8451 *) The addition of <Location> and <File> directives made the
8452 sub_req_lookup_simple() function bogus, so we now handle
8453 the special cases directly. [Dean Gaudet]
8455 *) We now try to log where the server is dumping core when a fatal
8456 signal is received. [Ken Coar]
8458 *) Improved lingering_close by adding a special timeout, removing the
8459 spurious log messages, removing the nonblocking settings (they
8460 are not needed with the better timeout), and adding commentary
8461 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8462 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]

8465 log instead of stderr. [Roy Fielding]
8467 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8469 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8470 processing a subrequest, allocate memory from r->main->pool instead
8471 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8472 in the middle of an SSI request. [Dean Gaudet] PR #122

8475 (was sending 405, now 404) and when any method is sent with a
8476 full-URI that doesn't match the server and the server is not acting
8477 as a proxy (was sending 501, now 403). [Roy Fielding]

8483 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8485 *) Report extra info from errno with many errors that cause httpd to exit.
8486 spawn_child, popenf, and pclosef now have valid errno returns in the
8487 event of an error. Correct problems where errno was stomped on
8488 before being reported. [Dean Gaudet]
8490 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8491 never called, and thus the filesystem would remain full indefinitely.
8492 We now also remove incomplete cache files left if the origin server
8493 didn't send a Content-Length header and either the client has aborted
8494 transfer or bwrite() to client has failed. [Petr Lampa]
8496 *) Fixed the handling of module and script-added header fields.
8497 Improved the interface for sending header fields and reduced
8498 the duplication of code between sending okay responses and errors.
8499 We now always send both headers_out and err_headers_out, and
8500 ensure that the server-reserved fields are not being overridden,
8501 while not overriding those that are not reserved. [Roy Fielding]
8503 *) Moved transparent content negotiation fields to err_headers_out
8504 to reflect above changes. [Petr Lampa]
8506 *) Fixed the determination of whether or not we should make the
8507 connection persistent for all of the cases where some other part
8508 of the server has already indicated that we should not. Also
8509 improved the ordering of the test so that chunked encoding will
8510 be set whenever it is desired instead of only when KeepAlive
8511 is enabled. Added persistent connection capability for most error
8512 responses (those that do not indicate a bad input stream) when
8513 accessed by an HTTP/1.1 client. [Roy Fielding]
8515 *) Added missing timeouts for sending header fields, error responses,
8516 and the last chunk of chunked encoding, each of which could have
8517 resulted in a process being stuck in write forever. Using soft_timeout
8518 requires that the sender check for an aborted connection rather than
8519 continuing after an EINTR. Timeouts that used to be initiated before
8520 send_http_header (and never killed) are now initiated only within or
8521 around the routines that actually do the sending, and not allowed to
8522 propagate above the caller. [Roy Fielding]
8524 *) mod_auth_anon required an @ or a . in the email address, not both.
8527 *) per_dir_defaults weren't set correctly until directory_walk for
8528 name-based vhosts. This fixes an obscure bug with the wrong config
8529 info being used for vhosts that share the same ip as the server.
8532 *) Improved generation of modules/Makefile to be more generic for
8533 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8535 *) Generate makefile dependency for Configuration based on the actual
8536 name given when running the Configure process. [Dean Gaudet]
8538 *) Fixed problem with vhost error log not being set prior to
8539 initializing virtual hosts. [Dean Gaudet]
8541 *) Fixed infinite loop when a trailing slash is included after a type map
8542 file URL (extra path info). [Petr Lampa]
8544 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8546 *) Add documentation for DNS issues (reliability and security), and try
8547 to explain the virtual host matching process. [Dean Gaudet]
8549 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8550 fails while parsing the configuration file. [Dean Gaudet]
8552 *) Improved calls to setsockopt. [Roy Fielding]
8554 *) Negotiation changes: Don't output empty content-type in variant list;
8555 Output charset in variant list; Return sooner from handle_multi() if
8556 no variants found; Add handling of '*' wildcard in Accept-Charset.
8557 [Petr Lampa and Paul Sutton]
8559 *) Fixed overlaying of request/sub-request notes and headers in
8560 mod_negotiation. [Dean Gaudet]
8562 *) If two variants' charset quality are equal and one is the default
8563 charset (iso-8859-1), then prefer the variant that was specifically
8564 listed in Accept-Charset instead of the default. [Petr Lampa]
8566 *) Memory allocation problem in push_array() -- it would corrupt memory
8567 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8569 *) invoke_handler() doesn't handle mime arguments in content-type
8572 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8575 *) Fixed problem with ErrorDocument not working for virtual hosts
8576 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8578 *) Log an error message if we get a request header that is too long,
8579 since it may indicate a buffer overflow attack. [Marc Slemko]
8581 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8582 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8583 [Ken Coar] PR #146, #187
8585 *) Added table entry placeholder for new header_parser callback
8586 in all of the distributed modules. [Ken Coar] PR #191
8588 *) Allow for cgi files without the .EXE extension on them under OS/2.
8589 [Garey Smiley] PR #59
8591 *) Fixed error message when resource is not found and URL contains
8592 path info. [Petr Lampa and Dean Gaudet] PR #40
8594 *) Fixed user and server confusion over what should be a virtual host
8595 and what is the main server, resulting in access to something
8596 other than the name defined in the virtualhost directive (but
8597 with the same IP address) failing. [Dean Gaudet]
8599 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8600 AIX; improves the redirection stuff to enable the users to generally
8601 redirect to http, https, gopher and ftp; added TIME variable for
8602 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8603 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8604 can be used in conjunction with %{TIME} or other variables to create
8605 time-dependent rewriting rules. [Ralf S. Engelschall]
8607 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8608 Module authors may need to adjust their code for proper cleanup to take
8609 place (that is, call note_cleanups_for_fd()). This change fixes problems
8610 with file descriptors being erroneously closed when the proxy module was
8611 in use. [Ben Laurie]
8613 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8614 initgroups() to hose the group information needed for later
8615 comparisons. [Randy Terbush]
8617 *) Remove unnecessary call to va_end() in create_argv() which
8618 caused a SEGV on some systems.
8620 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8623 *) Clear memory allocated for listeners. [Randy Terbush]
8625 *) Improved handling of IP address as a virtualhost address and
8626 introduced "_default_" as a synonym for the default vhost config.
8627 [Dean Gaudet] PR #212
8629 Changes with Apache 1.2b7
8631 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
8633 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
8635 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8636 - replace protocol response numbers with symbols
8637 - save variant-list into main request notes
8638 - free allocated memory from subrequests
8639 - merge notes, headers_out and err_headers_out
8641 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8642 "HTTP/#.# ###*" to be more lenient about what we accept.
8645 *) more proxy FTP bug fixes:
8646 - Changed send_dir() to remove user/passwd from displayed URL.
8647 - Changed login error messages to be more descriptive.
8648 - remove setting of SO_DEBUG socket option
8649 - Make ftp_getrc() more lenient about multiline responses,
8650 specifically, 230 responses which don't have continuation 230-
8651 on each line). These seem to be all NT FTP servers, and while
8652 perhaps questionable, they appear to be legal by RFC 959.
8653 - Add missing kill_timeout() after transfer to user completes.
8656 *) Fixed problem where a busy server could hang when restarting
8657 after being sent a SIGHUP due to child processes not exiting.
8660 *) Modify mod_include escaping so a '\' only signifies an escaped
8661 character if the next character is one that needs
8662 escaping. [Ben Laurie]
8664 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8665 used with a 'base' directive that does not have a '/' in it.
8666 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8668 *) Reduced the default timeout from 1200 seconds to 300, and the
8669 one in the sample configfile from 400 to 300. [Marc Slemko]
8671 *) Stop vbprintf from crashing if given a NULL string pointer;
8672 print (null) instead. [Ken Coar]
8674 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8675 [Marc Slemko and Roy Fielding]
8677 *) Fixed problem with mod_cgi-generated internal redirects trying to
8678 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8680 *) Reduced timeout on lingering close, removed possibility of a blocked
8681 read causing the child to hang, and stopped logging of errors if
8682 the socket is not connected (reset by client). [Roy Fielding]
8684 *) Rearranged main child loop to remove duplication of code in
8685 select/accept and keep-alive requests, fixed several bugs regarding
8686 checking scoreboard_image for exit indication and failure to
8687 account for all success conditions and trap all error conditions,
8688 prevented multiple flushes before closing the socket; close the entire
8689 socket buffer instead of just one descriptor, prevent logging of
8690 EPROTO and ECONNABORTED on platforms where supported, and generally
8691 improved readability. [Roy Fielding]
8693 *) Extensive performance improvements. Cleaned up inefficient use of
8694 auto initializers, multiple is_matchexp calls on a static string,
8695 and excessive merging of response_code_strings. [Dean Gaudet]
8697 *) Added double-buffering to mod_include to improve performance on
8698 server-side includes. [Marc Slemko]
8700 *) Several fixes for suexec wrapper. [Randy Terbush]
8701 - Make wrapper work for files on NFS filesystem.
8702 - Fix portability problem of MAXPATHLEN.
8703 - Fix array overrun problem in clean_env().
8704 - Fix allocation of PATH environment variable
8706 *) Removed extraneous blank line is description of mod_status chars.
8709 *) Logging of errors from the call_exec routine simply went nowhere,
8710 since the logfile fd has been closed, so now we send them to stderr.
8711 [Harald T. Alvestrand]
8713 *) Fixed core dump when DocumentRoot is a CGI.
8714 [Ben Laurie, reported by geddis@tesserae.com]
8716 *) Fixed potential file descriptor leak in mod_asis; updated it and
8717 http_core to use pfopen/pfclose instead of fopen/fclose.
8718 [Randy Terbush and Roy Fielding]
8720 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8721 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8722 [Dean Gaudet and Ken Coar]
8724 *) Return a 302 response code to the client when sending a redirect
8725 due to a missing trailing '/' on a directory instead of a 301; now
8726 it is cacheable. [Markus Gyger]
8728 *) Fix condition where, if a bad directive occurs in .htaccess, and
8729 sub_request() goes first to this directory, then log_reason() will
8730 SIGSEGV because it doesn't have initialized r->per_dir_config.
8731 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8733 *) Fix handling of lang_index in is_variant_better(). This was
8734 causing problems which resulted in the server sending the
8735 wrong language document in some cases. [Petr Lampa]
8737 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8738 the clean environment on some systems.
8740 *) Tweak byteserving code (e.g. serving PDF files) to work around
8741 bugs in Netscape Navigator and Microsoft Internet Explorer.
8742 Emit Content-Length header when sending multipart/byteranges.
8745 *) Port to HI-UX/WE2. [Nick Maclaren]
8747 *) Port to HP MPE operating system for HP 3000 machines
8748 [Mark Bixby <markb@cccd.edu>]
8750 *) Fixed bug which caused a segmentation fault if only one argument
8751 given to RLimit* directives. [Ed Korthof]
8753 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8755 *) Improved buffered output to the client by delaying the flush decision
8756 until the BUFF code is actually about to read the next request.
8757 This fixes a problem introduced in 1.2b5 with clients that send
8758 an extra CRLF after a POST request. Also improved chunked output
8759 performance by combining writes using writev() and removing as
8760 many bflush() calls as possible. NOTE: Platforms without writev()
8761 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8762 or Configure, unless we have already done so. [Dean Gaudet]
8764 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8766 *) Fixed mod_info output corruption bug introduced by buffer overflow
8767 fixes. [Dean Gaudet]
8769 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8770 for the special case of a 304 response. [Paul Sutton]
8772 *) Improved handling of TRACE method by bypassing normal method handling
8773 and header parsing routines; fixed Allow response to always allow TRACE.
8776 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8778 *) Cleaned-up some of the generated HTML. [Ken Coar]
8780 Changes with Apache 1.2b6
8782 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8784 *) Fix typo introduced in fix for potential infinite loop around
8785 accept() in child_main(). This change caused the rev to 1.2b6.
8786 1.2b5 was never a public beta.
8788 Changes with Apache 1.2b5
8790 *) Change KeepAlive semantics (On|Off instead of a number), add
8791 MaxKeepAliveRequests directive. [Alexei Kosut]
8793 *) Various NeXT compilation patches, as well as a change in
8794 regex/regcomp.c since that file also used a NEXT define.
8797 *) Allow * to terminate the end of a directory match in mod_dir.
8798 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8800 *) Don't call can_exec() if suexec_enabled. Calling this requires
8801 scripts executed by the suexec wrapper to be world executable, which
8802 defeats one of the advantages of running the wrapper. [Randy Terbush]
8804 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8807 *) Migration from sprintf() to snprintf() to avoid buffer
8808 overflows. [Marc Slemko]
8810 *) Provide portable snprintf() implementation (ap_snprintf)
8811 as well as *cvt family. [Jim Jagielski]
8813 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8816 *) Remove mod_fastcgi.c from the distribution. This module appears
8817 to be maintained more through the Open Market channels and should
8818 continue to be easily available at http://www.fastcgi.com/
8820 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8821 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8823 *) mod_info assumed that the config files were relative to ServerRoot.
8826 *) CGI scripts called as an error document resulting from failed
8827 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8829 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8832 *) Properly check errno to prevent display of a directory index
8833 when server receives a long enough URL to confuse stat().
8836 *) Several security enhancements to suexec wrapper. It is _highly_
8837 recommended that previously installed versions of the wrapper
8838 be replaced with this version. [Randy Terbush, Jason Dour]
8840 - ~user execution now properly restricted to ~user's home
8841 directory and below.
8842 - execution restricted to UID/GID > 100
8843 - restrict passed environment to known variables
8844 - call setgid() before initgroups() (portability fix)
8845 - remove use of setenv() (portability fix)
8847 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8849 *) Add access control via environment variables. [Ben Laurie]
8851 *) Add rflush() function. [Alexei Kosut]
8853 *) remove duplicate pcalloc() call in new_connection().
8855 *) Fix incorrect comparison which could allow number of children =
8856 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8857 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8859 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8860 AIX PS/2, CONVEXOS. [Jim Jagielski]
8862 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8863 It's more portable. [Martin Kraemer]
8865 *) Replace references to make in Makefile.tmpl with $(MAKE).
8868 *) Add ProxyBlock directive w/IP address caching. Add IP address
8869 caching to NoCache directive as well. ProxyBlock works with all
8870 handlers; NoCache now also works with FTP for anonymous logins.
8871 Still more code cleanup. [Chuck Murcko]
8873 *) Add "header parse" API hook [Ben Laurie]
8875 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8877 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8879 *) Correctly allow access and auth directives in <Files> sections in
8880 server config files. [Alexei Kosut]
8882 *) Fix bug with ServerPath that could cause certain files to be not
8883 found by the server. [Alexei Kosut]
8885 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8886 double-quote from text and so that it properly checks for unsupported
8887 status codes using the new index_of_response interface. [Roy Fielding]
8889 *) Multiple fixes to the lingering_close code in order to avoid being
8890 interrupted by a stray timeout, to avoid lingering on a connection
8891 that has already been aborted or never really existed, to ensure that
8892 we stop lingering as soon as any error condition is received, and to
8893 prevent being stuck indefinitely if the read blocks. Also improves
8894 reporting of error conditions. [Marc Slemko and Roy Fielding]
8896 *) Fixed initialization of parameter structure for sigaction.
8897 [mgyger@itr.ch, Adrian Filipi-Martin]
8899 *) Fixed reinitializing the parameters before each call to accept and
8900 select, and removed potential for infinite loop in accept.
8901 [Roy Fielding, after useful PR from adrian@virginia.edu]
8903 *) Fixed condition where, if a child fails to fork, the scoreboard would
8904 continue to say SERVER_STARTING forever. Eventually, the main process
8905 would refuse to start new children because count_idle_servers() will
8906 count those SERVER_STARTING entries and will always report that there
8907 are enough idle servers. [Phillip Vandry]
8909 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8910 Avoided calling bflush() when the client is pipelining requests.
8911 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8913 *) Added description of "." mode in server-status [Jim Jagielski]
8915 Changes with Apache 1.2b4
8917 *) Fix possible race condition in accept_mutex_init() that
8918 could leave a small security hole open allowing files to be
8919 overwritten in cases where the server UID has write permissions.
8922 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8924 *) Fix portablity problem in util_script where ARG_MAX may not be
8925 defined for some systems.
8927 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8930 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8931 style magic #! token for better script portability. [Garey Smiley]
8933 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8934 execution for ~userdir CGI. [Jason Dour]
8936 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8938 *) Fix month off by one in suexec wrapper logging.
8940 Changes with Apache 1.2b3:
8942 *) Fix error in mod_cgi which could cause resources not to be properly
8943 freed, or worse. [Dean Gaudet]
8945 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8947 *) Add set_flag_slot() at the request of Dirk and others.
8950 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8952 *) Add changes to improve the error message given for invalid
8953 ServerName parameters. [Dirk vanGulik]
8955 *) Add "Authoritative" directive for Auth modules that don't
8956 currently have it. This gives admin control to assign authoritative
8957 control to an authentication scheme and allow "fall through" for
8958 those authentication modules that aren't "Authoritative" thereby
8959 allowing multiple authentication mechanisms to be chained.
8962 *) Remove requirement for ResourceConfig/AccessConfig if not using
8963 the three config file layout. [Randy Terbush]
8965 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8967 *) Changes to suexec wrapper to fix the following problems:
8968 1. symlinked homedirs will kill ~userdirs.
8969 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8970 3. CGI command lines paramters problems
8971 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8972 [Randy Terbush, Jason Dour]
8974 *) Change create_argv() to accept variable arguments. This fixes
8975 a problem where arguments were not getting passed to the CGI via
8976 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8978 *) Collapse multiple slashes in path URLs to properly apply
8979 handlers defined by <Location>. [Alexei Kosut]
8981 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8983 *) Improve the accuracy of request duration timings by setting
8984 r->request_time in read_request_line() instead of read_request().
8987 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8988 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8990 *) Add the ability to pass different Makefile.tmpl files to Configure
8991 using the -make flag. [Rob Hartill]
8993 *) Fix coredump triggered when sending a SIGHUP to the server caused
8994 by an assertion failure, in turn caused by an uninitialised field in a
8998 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8999 PATH_INFO from previous versions of Apache (in certain situations,
9000 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
9001 [later removed in 1.2b11]
9003 *) Add rwrite() function to API to allow for sending strings of
9004 arbitrary length. [Doug MacEachern]
9006 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
9008 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
9009 NeXT. [Jim Jagielski]
9011 *) Removed recent modification to promote the status code on internal
9012 redirects, since the correct fix was to change the default log format
9013 in mod_log_config so that it outputs the original status. [Rob Hartill]
9015 Changes with Apache 1.2b2:
9017 *) Update set_signals() to use sigaction() for setting handlers.
9018 This appears to fix a re-entrant problem in the seg_fault()
9019 bus_error() handlers. [Randy Terbush]
9021 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
9023 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
9025 *) proxy_http.c bugfixes: [Chuck Murcko]
9026 1) fixes possible NULL pointer reference w/NoCache
9027 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
9028 host would cache nothing if it was in the local domain,
9029 and the local domain was in the NoCache list)
9030 3) Adds Host: header when not available
9031 4) Some code cleanup and clarification
9033 *) mod_include.c bugfixes:
9034 1) Fixed an ommission that caused include variables to not
9035 be parsed in config errmsg directives [Howard Fear]
9036 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
9037 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
9038 4) Allow backslash-escaping to all quoted text
9039 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
9040 5) Pass variable to command line if not set in XSSI's env
9043 *) Fix infinite loop when processing Content-language lines in
9044 type-map files. [Alexei Kosut]
9046 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
9048 *) Fixed problem in set_[user|group] that prevented CGI execution
9049 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
9051 *) Added PORTING information file. [Jim Jagielski]
9053 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
9055 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
9057 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
9058 USE_FCNTL_SERIALIZED_ACCEPT was intended.
9060 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
9061 which caused problems of systems where socket s_addr is >32bits.
9063 *) Added comment to explain (r->chunked = 1) side-effect in
9064 http_protocol.c [Roy Fielding]
9066 *) Replaced use of index() in mod_expires.c with more appropriate
9067 and portable isdigit() test. [Ben Laurie]
9069 *) Updated Configure for ...
9070 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9071 *-dg-dgux* (bad pattern match)
9072 QNX (DEF_WANTHSREGEX=yes)
9073 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9076 and added some user diagnostic info. [Ben Laurie]
9078 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9079 for better portability. [Jim Jagielski]
9081 *) Updated helpers/GuessOS for ...
9082 SCO 5 (recognize minor releases)
9083 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9084 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9085 IRIX64 (-sgi-irix64)
9086 ULTRIX (-unknown-ultrix)
9087 SINIX (-whatever-sysv4)
9088 NCR Unix (-ncr-sysv4)
9089 and fixed something in helpers/PrintPath [Ben Laurie]
9091 Changes with Apache 1.2b1
9093 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9095 Changes with Apache 1.1.1
9097 *) Fixed bug where Cookie module would make two entries in the
9098 logfile for each access [Mark Cox]
9100 *) Fixed bug where Redirect in .htaccess files would cause memory
9101 leak. [Nathan Neulinger]
9103 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9105 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9107 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9109 Changes with Apache 1.1.0
9111 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9113 *) Bring QNX support up to date. [Ben Laurie]
9115 *) Make virtual hosts default to main server keepalive parameters.
9116 [Alexei Kosut, Ben Laurie]
9118 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9120 *) Fix missing address family for connect, also remove unreachable statement
9121 in mod_proxy. [Ben Laurie]
9123 *) mod_env now turned on by default in Configuration.tmpl.
9125 *) Bugs which were fixed:
9126 a) yet more mod_proxy bugs [Ben Laurie]
9127 b) CGI works again with inetd [Alexei Kosut]
9128 c) Leading colons were stripped from passwords [osm@interguide.com]
9129 d) Another fix to multi-method Limit problem [jk@tools.de]
9131 Changes with Apache 1.1b4
9133 *) r->bytes_sent variable restored. [Robert Thau]
9135 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9137 *) More possibly unsecure programs removed from the support directory.
9139 *) More mod_auth_msql authentication improvements.
9141 *) VirtualHosts based on Host: headers no longer conflict with the
9144 *) OS/2 compatibility enhancements. [Gary Smiley]
9146 *) POST now allowed to directory index CGI scripts.
9148 *) Actions now work with files of the default type.
9150 *) Bugs which were fixed:
9151 a) more mod_proxy bugs
9152 b) early termination of inetd requests
9153 c) compile warnings on several systems
9154 d) problems when scripts stop reading output early
9156 Changes with Apache 1.1b3
9158 *) Much of cgi-bin and all of cgi-src has been removed, due to
9159 various security holes found and that we could no longer support
9162 *) The "Set-Cookie" header is now special-cased to not merge multiple
9163 instances, since certain popular browsers can not handle multiple
9164 Set-Cookie instructions in a single header. [Paul Sutton]
9166 *) rprintf() added to buffer code, occurrences of sprintf removed.
9169 *) CONNECT method for proxy module, which means tunneling SSL should work.
9170 (No crypto needed) Also a NoCache config directive.
9172 *) Several API additions: pstrndup(), table_unset() and get_token()
9173 functions now available to modules.
9175 *) mod_imap fixups, in particular Location: headers are now complete
9178 *) New "info" module which reports on installed module set through a
9179 special URL, a la mod_status.
9181 *) "ServerPath" directive added - allows for graceful transition
9182 for Host:-header-based virtual hosts.
9184 *) Anonymous authentication module improvements.
9186 *) MSQL authentication module improvements.
9188 *) Status module design improved - output now table-based. [Ben Laurie]
9190 *) htdigest utility included for use with digest authentication
9193 *) mod_negotiation: Accept values with wildcards to be treated with
9194 less priority than those without wildcards at the same quality
9195 value. [Alexei Kosut]
9197 *) Bugs which were fixed:
9198 a) numerous mod_proxy bugs
9199 b) CGI early-termination bug [Ben Laurie]
9200 c) Keepalives not working with virtual hosts
9201 d) RefererIgnore problems
9202 e) closing fd's twice in mod_include (causing core dumps on
9203 Linux and elsewhere).
9205 Changes with Apache 1.1b2
9208 a) core dumps in mod_digest
9209 b) truncated hostnames/ip address in the logs
9210 c) relative URL's in mod_imap map files
9212 Changes with Apache 1.1b1
9214 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9216 Changes with Apache 1.0.3
9218 *) Internal redirects which occur in mod_dir.c now preserve the
9219 query portion of a request (the bit after the question mark).
9222 *) Escape active characters '<', '>' and '&' in html output in
9223 directory listings, error messages and redirection links.
9226 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9228 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9231 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9233 *) Reset timeout timer after each successful fwrite() to the network.
9234 This patch adds a reset_timeout() procedure that is called by
9235 send_fd() to reset the timeout ever time data is written to the net.
9238 *) timeout() signal handler now checks for SIGPIPE and reports
9239 lost connections in a more user friendly way. [Rob Hartill]
9241 *) Location of the "scoreboard" file which used to live in /tmp is
9242 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9243 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9245 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9247 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9248 which caused a SEGV with cookies enabled
9250 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9253 *) Log the UNIX textual error returned by some system calls, in
9254 particular errors from accept() [David Robinson]
9256 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9258 Changes with Apache 1.0.2
9260 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9261 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9263 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9266 *) past changes to http_config.c to only use the
9267 setrlimit function on systems defining RLIMIT_NOFILE
9268 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9269 for SUNOS and prototypes the needed functions.
9271 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9274 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9276 *) Merge multiple headers from CGI scripts instead of taking last
9277 one. [David Robinson]
9279 *) Add support for SCO 5. [Ben Laurie]
9281 Changes with Apache 1.0.1
9283 *) Silence mod_log_referer and mod_log_agent if not configured
9286 *) Recursive includes can occur if the client supplies PATH_INFO data
9287 and the server provider uses relative links; as file.html
9288 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9290 *) The replacement for initgroups() did not call {set,end}grent(). This
9291 had two implications: if anything else used getgrent(), then
9292 initgroups() would fail, and it was consuming a file descriptor.
9295 *) On heavily loaded servers it was possible for the scoreboard to get
9296 out of sync with reality, as a result of a race condition.
9297 The observed symptoms are far more Apaches running than should
9298 be, and heavy system loads, generally followed by catastrophic
9299 system failure. [Ben Laurie]
9301 *) Fix typo in license. [David Robinson]
9303 Changes with Apache 1.0.0 23 Nov 1995
9305 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9307 Changes with Apache 0.8.16 05 Nov 1995
9309 *) New man page for 'httpd' added to support directory [David Robinson]
9311 *) .htgroup files can have more than one line giving members for a
9312 given group (each must have the group name in front), for NCSA
9313 back-compatibility [Robert Thau]
9315 *) Mutual exclusion around accept() is on by default for SVR4 systems
9316 generally, since they generally can't handle multiple processes in
9317 accept() on the same socket. This should cure flaky behavior on
9318 a lot of those systems. [David Robinson]
9320 *) AddType, AddEncoding, and AddLanguage directives take multiple
9321 extensions on a single command line [David Robinson]
9323 *) UserDir can be disabled for a given virtual host by saying
9324 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9325 that this didn't work. [David Robinson]
9327 *) Compiles on QNX [Ben Laurie]
9329 *) Corrected parsing of ctime time format [David Robinson]
9331 *) httpd does a perror() before exiting if it can't log its pid
9332 to the PidFile, to make diagnosing the error a bit easier.
9335 *) <!--#include file="..."--> can no longer include files in the
9336 parent directory, for NCSA back-compatibility. [David Robinson]
9338 *) '~' is *not* escaped in URIs generated for directory listings
9341 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9343 *) Fixed bug involving handling URIs with escaped %-characters
9344 in redirects [David Robinson]
9346 Changes with Apache 0.8.15 14 Oct 1995
9348 *) Switched to new, simpler license
9350 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9352 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9354 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9356 *) Correctly handles internal redirects to files with names containing '%'
9359 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9361 *) Use geteuid() rather than getuid() to see if we have root privilege,
9362 so that server correctly resets privilege if run setuid root. [Andrew
9365 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9368 *) Fix relative URLs in imagemap files [Randy Terbush]
9370 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9373 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9374 entries all name the same one. [David Robinson]
9376 *) Fix directory listings with filenames containing unusual characters
9379 *) Better URI-escaping for generated URIs in directories with filenames
9380 containing unusual characters [Ben Laurie]
9382 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9384 *) Unblock alarms on error return from spawn_child() [David Robinson]
9386 *) Sample Config files have extra note for SCO users [Ben Laurie]
9388 *) Configuration has note for HP-UX users [Rob Hartill]
9390 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9392 *) Nuked bogus #define in httpd.h [David Robinson]
9394 *) Better test for whether a system has setrlimit() [David Robinson]
9396 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9398 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9401 Changes with Apache 0.8.14 19 Sep 1995
9403 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9405 *) AddDescription works (better) [Ben Laurie]
9407 *) Leaves an intelligible error diagnostic when it can't set group
9408 privileges on standalone startup [Andrew Wilson]
9410 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9411 that machine, which claims to be BSD but does not support RLIMIT.
9414 *) gcc -Wall no longer complains about an unused variable when util.c
9415 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9417 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9419 Changes with Apache 0.8.13 07 Sep 1995
9421 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9423 *) Have built-in imagemap code recognize & honor Point directive [James
9426 *) Generate cleaner directory listings in directories with a mix of
9427 long and short filenames [Rob Hartill]
9429 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9431 *) Properly default ServerName for virtual servers [Robert Thau]
9433 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9434 Paul Richards and a cast of thousands...]
9436 *) On self-identified BSD systems (we don't try to guess any more),
9437 allocate a few extra file descriptors per virtual host with setrlimit,
9438 if we can, to avoid running out. [Randy Terbush]
9440 *) Write 22-character lock file name into buffer with enough space
9441 on startup [Konstantin Olchanski]
9443 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9446 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9448 *) Suppress -Wall warning by initializing variable in negotiation code
9449 [Tobias Weingartner]
9451 Changes with Apache 0.8.12 31 Aug 1995
9453 *) Doesn't pause three seconds after including a CGI script which is
9454 too slow to die off (this is done by not even trying to kill off
9455 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9456 after the entire document has been processed). [Robert Thau]
9458 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9460 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9462 *) Allows .htaccess files to override <Directory> sections naming the
9463 same directory [David Robinson]
9465 *) Removed an efficiency hack in sub_req_lookup_uri which was
9466 causing certain extremely marginal cases (e.g., ScriptAlias of a
9467 *particular* index.html file) to fail. [David Robinson]
9469 *) Doesn't log an error when the requested URI requires
9470 authentication, but no auth header line was supplied by the
9471 client; this is a normal condition (the client doesn't no auth is
9472 needed here yet). [Robert Thau]
9474 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9476 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9478 *) RFC931 code no longer passes out name of prior clients on current
9479 requests if the current request came from a server that doesn't
9480 do RFC931. [David Robinson]
9482 *) Configuration script accepts "Module" lines with trailing whitespace.
9485 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9487 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9489 Changes with Apache 0.8.11 24 Aug 1995
9491 *) Wildcard <Directory> specifications work. [Robert Thau]
9493 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9495 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9496 the file being requested itself, in addition to the directories leading
9497 up to it. [Robert Thau]
9499 *) Logs access failures due to symlink checks or invalid client address
9500 in the error log [Roy Fielding, Robert Thau]
9502 *) Symlink checks deal correctly with systems where lstat of
9503 "/path/to/some/link/" follows the link. [Thau, Fielding]
9505 *) Doesn't reset DirectoryIndex to 'index.html' when
9506 other directory options are set in a .htaccess file. [Robert Thau]
9508 *) Clarified init code and nuked bogus warning in mod_access.c
9511 *) Corrected several directives in sample srm.conf
9512 --- includes corrections to directory indexing icon-related directives
9513 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9514 icons for encodings right, and turning on AddEncoding by default).
9517 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9520 *) INSTALL & README mention "contributed modules" directory [Brian
9523 *) Fixed English in the license language... "for for" --> "for".
9526 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9527 mod_alias.c, merging it almost completely with handling of Alias, and
9528 adding a 'notes' field to the request_rec which allows the CGI module
9529 to discover whether the Alias module has put this request through
9530 ScriptAlias (which it needs to know for back-compatibility, as the old
9531 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9534 Changes with Apache 0.8.10 18 Aug 1995
9536 *) AllowOverride applies to the named directory, and not just
9537 subdirectories. [David Robinson]
9539 *) Do locking for accept() exclusion (on systems that need it)
9540 using a special file created for the purpose in /usr/tmp, and
9541 not the error log; using the error log causes real problems
9542 if it's NFS-mounted; this is known to be the cause of a whole
9543 lot of "server hang" problems with Solaris. [David Robinson;
9544 thanks to Merten Schumann for help diagnosing the problem].
9546 Changes with Apache 0.8.9 12 Aug 1995
9548 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9550 *) Nested includes see environment variables of the including document,
9551 for NCSA bug-compatibility (some sites have standard footer includes
9552 which try to print out the last-modified date). [Eric Hagberg/Robert
9555 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9556 URI as a CGI script, even if it would have been treated as something
9557 else if requested directly, for NCSA back-compatibility. (Note that
9558 this means that people who know the name of the script can see the
9559 code just by asking for it). [Robert Thau]
9561 *) New version of dbmmanage script included in support directory as
9564 *) Check if scoreboard file couldn't be opened, and say so, rather
9565 then going insane [David Robinson]
9567 *) POST to CGI works on A/UX [Jim Jagielski]
9569 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9571 *) NCSA server push works properly --- the Arena bug compatibility
9572 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9573 if you still want the workaround). [Rob Hartill]
9575 *) If client didn't submit any Accept-encodings, ignore encodings in
9576 content negotiation. (NB this will all have to be reworked anyway
9577 for the new HTTP draft). [Florent Guillaume]
9579 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9581 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9583 *) Give Redirect priority over Alias, for NCSA bug compatibility
9586 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9587 paralleling earlier bug fix for CGI [David Robinson]
9589 *) If DBM auth is improperly configured, report a server error and don't
9592 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9593 it seems to work well enough without it (even in a 10 hits/sec
9594 workout), and the overhead for the locking under A/UX is
9595 alarmingly high (though it is very low on other systems).
9596 [Eric Hagberg, Jim Jagielski]
9598 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9600 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9601 Behlendorf/Eric Hagberg]
9603 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9605 *) Compiles clean on NEXT [Rob Hartill]
9607 *) Compiles clean on SGI [Robert Thau]
9609 Changes with Apache 0.8.8 08 Aug 1995
9611 *) SunOS library prototypes now never included unless explicitly
9612 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9613 people using GNU libc on SunOS are screwed by prototypes for the
9616 (Those who wish to compile clean with gcc -Wall on a standard
9617 SunOS setup need the prototypes, and may obtain them using
9618 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9619 with nonstandard libraries are presumably competent to make their
9622 *) Strips trailing '/' characters off both args to the Alias command,
9623 to make 'Alias /foo/ /bar/' work.
9625 Changes with Apache 0.8.7 03 Aug 1995
9627 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9628 [reported by David Robinson]
9630 *) Compiles clean on OSF/1 [David Robinson]
9632 *) Added some of the more recent significant changes (AddLanguage stuff,
9633 experimental LogFormat support) to CHANGES file in distribution root
9636 Changes with Apache 0.8.6 02 Aug 1995
9638 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9639 (If you actually wanted a conditional GET which bypassed the cache, you
9640 couldn't get it). [Reported by Roy Fielding]
9642 *) Properly terminate headers on '304 Not Modified' replies to conditional
9643 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9644 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9646 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9648 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9649 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9650 and older versions don't set the __SUNPRO_C preprocessor variable). On
9651 all other systems, these are never used anyway. [Reported by Mark Cox].
9653 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9655 Changes with Apache 0.8.5 01 Aug 1995
9657 *) Added last-minute configurable log experiment, as optional module
9659 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9660 properly. (One-line fix to http_protocol.c).
9662 *) Work around bogus behavior when reloading from Netscape.
9663 It's Netscape's bug --- for some reason they expect a request with
9664 If-modified-since: to not function as a conditional GET if it also
9665 comes with Pragma: no-cache, which is way out of line with the HTTP
9666 spec (according to Roy Fielding, the redactor).
9668 *) Added parameter to set maximum number of server processes.
9670 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9673 *) IdentityCheck bugfix [Chuck Murcko].
9675 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9677 *) More sample config file corrections; add extension to AddType for
9678 *.asis, move AddType generic description to its proper place, and
9679 fix miscellaneous typos. [ Alexei Kosut ]
9681 *) Deleted the *other* reference to the regents from the Berkeley
9682 legal disclaimer (everyplace).
9684 *) Nuked Shambhala name from src/README; had already cleaned it out
9687 Changes with Apache 0.8.4
9689 *) Changes to server-pool management parms --- renamed current
9690 StartServers to MinSpareServers, created separate StartServers
9691 parameter which means what it says, and renamed MaxServers to
9692 MaxSpareServers (though the old name still works, for NCSA 1.4
9693 back-compatibility). The old names were generally regarded as
9694 too confusing. Also altered "docs" in sample config files.
9696 *) More improvements to default config files ---
9697 sample directives (commented out) for XBitHack, BindAddress,
9698 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9699 defaults, AddTypes for send-as-is and imagemap magic types, and
9700 improvements to samples for DirectoryIndex [Alexei Kosut]
9702 *) Yet more improvements to default config files --- changes to
9703 Alexei's sample AddLanguage directives, and sample LanguagePriority
9704 [ Florent Guillaume ]
9706 *) Set config file locations properly if not set in httpd.conf
9709 *) Don't escape URIs in internal redirects multiple times; don't
9710 do that when translating PATH_INFO to PATH_TRANSLATED either.
9713 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9715 Changes with Apache 0.8.3
9717 *) Edited distribution README to *briefly* summarize installation
9718 procedures, and give a pointer to the INSTALL file in the src/
9721 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9722 recent NCSA distributions.
9724 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9725 exist for the same directory, use both and don't segfault. [Reported
9728 *) Proper makefile dependencies [David Robinson]
9730 *) Note (re)starts in error log --- reported by Rob Hartill.
9732 *) Only call no2slash() after get_path_info() has been done, to
9733 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9734 reported by Andrew Wilson, though this one is probably a real bug]
9736 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9737 dump core when Referer is not supplied. [Randy Terbush]
9739 *) Lightly edited sample config files to refer people to our documentation
9740 instead of NCSA's, and to list Rob McCool as *original* author (also
9741 deleted his old, and no doubt non-functional email address). Would be
9742 nice to have examples of new features...
9744 Changes with Apache 0.8.2 19 Jul 1995
9746 *) Added AddLanuage code [Florent Guillaume]
9748 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9750 *) All sorts of problems when MultiViews finds a directory. It would
9751 be nice if mod_dir.c was robust enough to handle that, but for now,
9752 just punt. [reported by Brian Behlendorf]
9754 *) Wait for all children on restart, to make sure that the old socket
9755 is gone and we can reopen it. [reported by Randy Terbush]
9757 *) Imagemap module is enabled in default Configuration
9759 *) RefererLog and UserAgentLog modules properly default the logfile
9762 *) Mark Cox's mod_cookies added to the distribution as an optional
9763 module (commented out in the default Configuration, and noted as
9764 an experiment, along with mod_dld). [Mark Cox]
9766 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9768 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9770 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9772 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9775 Changes with Apache 0.8.1
9777 *) New imagemap module [Randy Terbush]
9779 *) Replacement referer log module with NCSA-compatible RefererIgnore
9780 [Matthew Gray again]
9782 *) Don't mung directory listings with very long filenames.
9785 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9787 *) New config script. See INSTALL for info. [Robert Thau]
9789 *) Scoreboard mechanism for regulating the number of extant server
9790 processes. MaxServers and StartServers defaults are the same as
9791 for NCSA, but the meanings are slightly different. (Actually,
9792 I should probably lower the MaxServers default to 10).
9794 Before asking for a new connection, each server process checks
9795 the number of other servers which are also waiting for a
9796 connection. If there are more than MaxServers, it quietly dies
9797 off. Conversely, every second, the root, or caretaker, process
9798 looks to see how many servers are waiting for a new connection;
9799 if there are fewer than StartServers, it starts a new one. This
9800 does not depend on the number of server processes already extant.
9801 The accounting is arranged through a "scoreboard" file, named
9802 /tmp/htstatus.*, on which each process has an independent file
9803 descriptor (they need to seek without interference).
9805 The end effect is that MaxServers is the maximum number of
9806 servers on an *inactive* server machine, but more will be forked
9807 off to handle unusually heavy loads (or unusually slow clients);
9808 these will die off when they are no longer needed --- without
9809 reverting to the overhead of full forking operation. There is a
9810 hard maximum of 150 server processes compiled in, largely to
9811 avoid forking out of control and dragging the machine down.
9812 (This is arguably too high).
9814 In my server endurance tests, this mechanism did not appear to
9815 impose any significant overhead, even after I forced it to put the
9816 scoreboard file on a normal filesystem (which might have more
9817 overhead than tmpfs). [Robert Thau]
9819 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9822 *) Read .htaccess files even in directory with <Directory> section.
9823 (Former incompatibility noted on mailing list, now fixed). [Robert
9826 *) "HEAD /" gives the client a "Bad Request" error message, rather
9827 than trying to send no body *and* no headers. [Cliff Skolnick].
9829 *) Don't produce double error reports for some very obscure cases
9830 mainly involving auth configuration (the "all modules decline to
9831 handle" case which is a sure sign of a server bug in most cases,
9832 but also happens when authentication is badly misconfigured).
9835 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9836 it's *for*, and this sort of thing really shouldn't be cluttering
9837 up the Makefile). [Robert Thau]
9839 *) Incidental code cleanups in http_main.c --- stop dragging
9840 sa_client around; just declare it where used. [Robert Thau]
9842 *) Another acc-related fix. (It doesn't like const char
9843 in some places...). [Mark Cox]
9845 Changes with Shambhala 0.6.1 13 Jul 1995
9847 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9848 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9850 *) Compiles clean with acc on SunOS [Paul Sutton]
9852 *) Reordered modules in modules.c so that Redirect takes priority
9853 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9854 believe it or not, he has an actual site with a ScriptAlias and
9855 a Redirect declared for the *exact same directory*. Even *my*
9856 compatibility fetish wouldn't motivate me to fix this if the fix
9857 required any effort, but it doesn't, so what the hey.
9859 *) Fixed to properly default several server_rec fields for virtual
9860 servers from the corresponding fields in the main server_rec.
9861 [Cliff Skolnick --- 'port' was a particular irritant].
9863 *) No longer kills off nph- child processes before they are
9864 finished sending output. [Matthew Gray]
9866 Changes with Shambhala 0.6.0 10 Jul 1995
9868 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9869 the connection to the client in an "aborted" state, but otherwise
9870 allow whatever handlers are running to clean up. hard_timeout()s
9871 abort the request in progress completely; anything not tied to some
9872 resource pool cleanup will leak. They're still around because I
9873 haven't yet come up with a more elegant way of handling
9874 timeouts when talking to something that isn't the client. The
9875 default_handler and the dir_handler now use soft timeouts, largely
9876 so I can test the feature. [Robert Thau]
9878 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9879 the case of log handlers dying prematurely is probably handled VERY
9880 gracelessly at this point, and if the logger stops reading input,
9881 the server will hang. (It is known to correctly restart the
9882 logging process on server restart; this is (should be!) going through
9883 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9884 script). [Robert Thau]
9886 *) asis files supported (new module). [Robert Thau]
9888 *) IdentityCheck code is compiled in, but has not been tested. (I
9889 don't know anyone who runs identd). [Robert Thau]
9891 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9892 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9894 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9896 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9897 as timeouts are not in scope. [Robert Thau]
9899 *) quoted-string args in config files now handled correctly (doesn't drop
9900 the last character). [Robert Thau; reported by Randy Terbush]
9902 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9903 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9905 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9906 default default type); the former default default behavior when all
9907 type-checkers defaulted had been a core dump. [Paul Sutton]
9909 *) Copy filenames out of the struct dirent when indexing
9910 directories. (On Linux, readdir() returns a pointer to the same
9911 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9913 Changes with Shambhala 0.5.3 [not released]
9915 *) Default response handler notes "file not found" in the error log,
9916 if the file was not found. [Cliff Skolnick].
9918 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9919 code no longer sets up bogus PATH_INFO which fakes out the directory
9920 handler). [Cliff Skolnick]
9922 Changes with Shambhala 0.5.2 06 Jul 1995
9924 *) Changes to http_main.c --- root server no longer plays silly
9925 games with SIGCHLD, and so now detects and replaces dying
9926 children. Child processes just die on SIGTERM, without taking
9927 the whole process group with them. Potential problem --- if any
9928 child process refuses to die, we hang in restart.
9929 MaxRequestsPerChild may still not work, but it certainly works
9930 better than it did before this! [Robert Thau]
9932 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9933 work (or work better, at least); over-long description lines
9934 properly terminated. [Mark Cox]
9936 *) http_request.c now calls unescape_url() more places where it
9937 should [Paul Sutton].
9939 *) More directory handling bugs (reported by Cox)
9940 Parent Directory link is now set correctly. [Robert Thau]
9942 Changes with Shambhala 0.5.1 04 Jul 1995
9944 *) Generalized cleanup interface in alloc.c --- any function can be
9945 registered with alloc.c as a cleanup for a resource pool;
9946 tracking of files and file descriptors has been reimplemented in
9947 terms of this interface, so I can give it some sort of a test.
9950 *) More changes in alloc.c --- new cleanup_for_exec() function,
9951 which tracks down and closes all file descriptors which have been
9952 registered with the alloc.c machinery before the server exec()s a
9953 child process for CGI or <!--#exec-->. CGI children now get
9954 started with exactly three file descriptors open. Hopefully,
9955 this cures the problem Rob H. was having with overly persistent
9956 CGI connections. [Robert Thau]
9958 *) Mutual exclusion around the accept() in child_main() --- this is
9959 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9960 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9961 This uses fcntl(F_SETLK,...) on the error log descriptor because
9962 flock() on that descriptor won't work on systems which have BSD
9963 flock() semantics, including (I think) Linux 1.3 and Solaris.
9965 This does work on SunOS (when the server is idle, only one
9966 process in the pool is waiting on accept()); it *ought* to work
9967 on the other systems. [Robert Thau]
9969 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9971 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9973 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9975 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9976 be unnecessary if I go to the revised timeout-handling scheme).
9979 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9980 string) even if none came in with the request. [Robert Thau]
9982 *) CHANGES file added to distribution ;-).
9984 Changes with Shambhala 0.4.5
9986 *) mod_dld --- early dynamic loading support [rst]
9987 *) Add wildcard content handlers for XBITHACK; default_hander now
9988 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9989 *) XBITHACK supported as a wildcard content-handler, and
9990 configurable at run-time (not just at compile time, as in the
9991 "patchy server" releases) [rst]
9993 Changes with Shambhala 0.4.4 30 Jun 1995
9995 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9996 *) Handle Addtype x/y .z [rst, reported by Cox]
9998 Changes with Shambhala 0.4.3
10000 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
10001 synonymous [rst, terbush]
10003 Changes with Shambhala 0.4.1 28 Jun 1995
10005 *) First-cut virtual host implementation; some refit in the config
10006 reading code, and log management, was necessary to support this [rst]
10007 *) Sub-pool machinery, originally added to avoid excessive storage
10008 allocation on listings of large directories (which turned out to
10009 be the problem that the 0.3 storage accounting was added to
10010 find). Subrequests and mod_dir changed to use subpools. [rst]
10011 *) More memory debugging --- free list consistency checks. [rst]
10012 *) Added err_headers to request_rec, with support elsewhere [rst]
10013 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
10015 Changes with Shambhala 0.3 19 Jun 1995
10017 *) Switch ONE_PROCESS to a runtime command-line option (-X)
10018 *) Don't compile in mod_ai_backcompat by default
10019 *) Switch name of server from Apache to Shambhala in Makefile
10020 *) Add some accounting routines to track memory usage in the pools,
10023 Changes with Shambhala 0.2
10025 *) Set DOCUMENT_ROOT CGI variable
10026 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
10027 *) Add critical section protection to handling of cleanup structures
10029 *) Significant code reorg within the server core to group related
10030 functions together [rst]
10031 *) Correctly handle clients that hang up before sending any request
10033 *) Replace dying child processes. [rst]
10035 Changes with Shambhala 0.1 12 Jun 1995
10037 Major rewrite of the pre-existing "patchy server" codebase, by
10038 Robert Thau (rst). Significant portions of the server code, such
10039 as configuration-file handling and HTTP authentication support,
10040 were ripped out and rewritten from scratch. Code that was not
10041 completely rewritten was significantly altered.
10043 Major changes with this release include:
10045 *) Introduction of the module API; in request handling, the central
10046 machinery just dispatches to various modules, which actually do
10047 most of the work. Configuration handling is similar --- modules
10048 declare their own commands, and the central machinery just
10049 dispatches to them.
10051 API features from shambhala/0.1 were substantially unchanged in
10052 Apache 1.0 and 1.1. (1.0 API features not yet present in this
10053 release, such as wildcard handlers and subpools, were added in
10054 subsequent Shambhala releases, and were also generally rst's
10057 *) This release included the following modules:
10059 mod_access (access control --- allow and deny directives),
10060 mod_alias (Alias and Redirect commands),
10061 mod_auth (straight HTTP authentication, based on flat-files)
10062 mod_auth_dbm (same, with dbm files)
10063 mod_cgi (CGI scripts and, in this release, ScriptAlias)
10064 mod_common_log (CLF access logs; later renamed mod_log_common)
10065 mod_dir (directory indexing)
10066 mod_include (server-side includes)
10067 mod_mime (AddType directives)
10068 mod_negotiation (content negotiation)
10069 mod_userdir (support for users' public_html directories)
10071 It also included a mod_ai_backcompat, which was a private hack
10072 for back-compatibility with rst's own AI-lab servers.
10074 All of these modules were substantially complete, and functional
10075 or nearly so (a few, which implemented features not in use at
10076 Thau's site, required patches of a few lines).
10078 *) sub-request machinery, to allow modules to determine how other
10079 modules would assign MIME types to a given file, or optionally
10080 serve its content (this is heavily used by mod_dir, mod_include
10081 and mod_negotiation).
10083 *) Resource pool system for keeping track of memory allocated and
10084 files opened in service of a particular request. Much of the
10085 code in the modules (when they weren't rewrites) was adjusted to
10086 replace a pervasive convention of using fixed-size buffers on
10087 the stack with an equally pervasive convention of using memory
10088 allocated with palloc().
10090 *) Reorganization of data structures associated with a given
10091 request to eliminate use of global variables and the troublesome
10092 unmunge_name function (used in NCSA and early Apache releases to
10093 attempt to determine the URI which mapped to a given filename
10094 --- a difficult proposition, given that it is easy to produce
10095 setups in which multiple URIs map to the same file).
10097 *) Source files renamed and rearranged
10099 *) Very simple pre-forking behavior --- parent process forked off a
10100 fixed number of children, and then just waited for SIGHUP.
10102 *) Other more minor changes too numerous to list.
10104 This release included modified versions of a lot of code from the
10105 Apache 0.6.4 public release, plus an early pre-forking patch
10106 codeveloped by Robert Thau and Rob Hartill.
10108 Changes with Apache 0.7.3 20 Jun 1995
10110 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10111 were incorporated by Rob Hartill on the main branch while Robert Thau
10112 worked on the Shambhala rewrite above. Most were merged into the
10113 Shambala architecture after Apache 0.8.0.
10115 Changes with Apache 0.6.4 13 May 1995
10117 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10120 Changes with Apache 0.5.1 10 Apr 1995
10122 Changes with Apache 0.4 02 Apr 1995
10124 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10127 Changes with Apache 0.3 24 Mar 1995
10129 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10132 Changes with Apache 0.2 18 Mar 1995
10134 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10135 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10136 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
