1 Changes with Apache 2.0.25-dev
3 *) The prefork and OS/2 MPMs are overwriting the pid file when a second copy
4 of httpd is started and shuts down due to socket conflict. Moving the
5 call to ap_log_pid solves the problem.
7 *) Changed the late-1.3 log_config substitution %c to %X, to log the
8 status of the closed connection, as it conflicts with the far more
9 common, historical ssl logging directive %...{var}c. [William Rowe]
11 *) Added the common error/ tree to the build/install targets
12 (similar to the common icons/ tree) for the multi-language error
13 messages that Lars committed earlier. [William Rowe]
15 *) Added a multi process, multi threaded OS/2 MPM mpmt_os2. [Brian Havard]
17 *) Added a default commented-out mod_ldap and mod_auth_ldap
18 configuration to httpd-std.conf and httpd-win.conf
21 *) Added documentation for mod_ldap and mod_auth_ldap.
24 *) Enabled negative caching on attribute comparisons in the LDAP cache.
25 Fixed a problem where the default cache TTL was set in milliseconds
26 not microseconds causing the cache to time out almost immediately.
29 *) Fixed all the #if APR_HAS_SHARED_MEMORY checks within the LDAP
30 module code to follow APR. [Graham Leggett]
32 *) Fixed LDAP cleanup on graceful restarts. LDAP connections are now
33 cleaned up when the connection pool pool is cleaned up.
36 *) Fix a minor issue with Jeff Trawick's mod_include
37 patch. Without this patch, the code will just allocate
38 more bytes in get_combined_directive than are needed.
41 *) Added the LDAP authentication module mod_auth_ldap.
42 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
44 *) Added the LDAP cache and connection pooling module mod_ldap.
45 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
47 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
48 by allowing a module to disable itself if its prerequisites are not
49 met. [Justin Erenkrantz]
51 Changes with Apache 2.0.24
53 *) Fix a couple of issues in mod_include when the tag appeared at
54 offsets near 8192 in the file being parsed. [Jeff Trawick]
56 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
57 reached. [Jeff Trawick]
59 *) Numerous improvements to the Win32 build system. Introduced command line
60 builds without requiring .mak files for MSVC 6.0 and later versions.
61 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
64 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
65 reporting of uninstalled services and other error conditions, and changed the
66 default service name to Apache2. [William Rowe]
68 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
69 compatibility with existing Apache 1.3 Win32 Apache management utilites.
70 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
72 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
73 [William Rowe, Greg Ames]
75 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
76 and RemoveCharset directives. [William Rowe]
78 *) The Unix MPMs other than perchild now allow child server
79 processes to use the accept mutex when starting as root and
80 using SysV sems for the accept mutex. Previously, this
81 combination would lead to fatal errors in the child server
82 processes. perchild can't use SysV sems because of security
83 issues. [Jeff Trawick, Greg Ames]
85 *) Added Win32 revision stamp resources to all http binaries
86 (including modules/ and support/ tools.) PR7322 [William Rowe]
88 *) Fix ap_rvprintf to support more than 4K of data at one time.
89 [Cody Sherr <csherr@covalent.net>]
91 *) We have always used the obsolete/deprecated Netscape syntax
92 for our tracking cookies; now the CookieStyle directive
93 allows the Webmaster to choose the Netscape, RFC2109, or
94 RFC2965 format. The new CookieDomain directive allows the
95 setting of the cookie's Domain= attribute, too. PR #s 5006,
96 5023, 5920, 6140 [Ken Coar]
98 *) Tweak server/Makefile so that the rules for generating exports.c
99 are compatible with make utilities which don't expand wildcards
100 in a dependency list (e.g., OS/390 make, certain levels of GNU
101 make). [Jeff Trawick]
103 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
105 *) Begin to sanitize the MPM configuration directives. Now, all
106 MPMs use the same functions for all common MPM directives. This
107 should make it easier to catch all bugs in these directives once.
108 [Cody Sherr <csherr@covalent.net>]
110 *) Close a major resource leak. Every time we had issued a
111 graceful restart, we leaked a socket descriptor.
114 *) Fix a problem with the new method code. We need to cast
115 the 1 to an apr_int64_t or it will be treated as a 32-bit
116 integer, and it will wrap after being shifted 32 times.
117 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
119 *) Fix a bug in mod_expires. Previous to this patch, if you
120 told mod_expires to add 604800 seconds to the last-modified
121 time, it actually added 604800 usec's to the last-modified time,
122 so that when looking at the response it looked like nothing
123 had been done. The root of the problem was that we always compute
124 time in usec's, but we ask users to input sec's. This means we
125 need to convert to usec's before using those values.
128 *) The worker MPM now handles shutdown and restart requests. It
129 definitely isn't perfect, but we do stop the servers correctly.
130 The biggest problem right now is that SIGHUP causes the server to
131 just die. [Ryan Bloom]
133 Changes with Apache 2.0.23
135 *) Use the prefork MPM by default on Unix. [various]
137 *) Added a systray icon monitor application for Win32.
138 [Mladen Turk <mturk@mappingsoft.com>]
140 *) mod_rewrite: Fix the line ending on some non-Unix systems for
141 messages written to the rewrite log.
142 [Richard Labennett <rlabenn@us.ibm.com>]
144 *) All mod_autoindex query parsing is now quietly quashed with the
145 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
146 still drops the column sort <a href>'s for the column headers, but
147 IgnoreClient is required to ignore these Query options entirely.
150 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
151 to allow the client to select plain, FancyIndexing or HTMLTable
152 formatting, V=[0|1] to inhibit or enable version sorting, and
153 P=pattern to return only specific files. The old Query Arguments
154 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
155 as before), and O=A|D for ordering ascending or descending.
158 *) Fixed an error in mod_include's directive parsing routines which
159 caused #if, #elif, and #else expressions containing backslashes
160 to be improperly evaluated. [Cliff Woolley]
162 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
163 drop the icon column, SuppressRules to drop the <hr> elements,
164 and HTMLTable to create rudimentary HTML table listings (implies
165 FancyIndexing). [William Rowe]
167 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
168 from Apache 1.3.15. This is needed for two reasons, first, given
169 multiple machines within a server farm, ETags and Last-Modified
170 stamps won't correspond from machine to machine, and second, many
171 Unixes don't capture changes to the date or time stamp of existing
172 files, since these don't modify the dirent itself. [William Rowe]
174 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
175 and DirectoryWidth options from Apache 1.3.10.
176 [William Rowe, Ken Coar]
178 *) Eliminated FancyIndexing directive, deprecated early in Apache
179 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
181 *) mod_autoindex now excludes any file names that would result in
182 an error, other than a success or redirect. Also optimized
183 the parent directory, always included except in the URI '/'.
186 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
187 negotiated index pages, and prevent the server from defaulting
188 to an autoindex of the directory. mod_negotiation will now die
189 with a 500 Internal Error if it could match some filenames
190 (e.g. for mod_dir) but none can be served. mod_negotation now
191 refuses to serve any file with an extention that mod_mime doesn't
192 recognize, and wasn't part of the request. [William Rowe]
194 *) Eliminate mod_cgi's handling of .exe files without the .exe file
195 extension. This is already handled by multiviews, if the admin
196 wishes to AddHandler .exe or define a content type handler and
197 associate .exe files with that content type. Multiviews must be
198 enabled to allow these to be served. [William Rowe]
200 *) Speed up the server's response to a spike in incoming workload
201 or restarts by assigning empty scoreboard slots to new processes
202 when they are available. [Greg Ames]
204 *) Add a handler to mod_includes.c. This handler is designed to
205 implement the XbitHack directive. This can't be done with a
206 fixup, because we need to check the content-type, which is
207 only available in the handler phase. [Ryan Bloom]
209 *) Make the includes filter check return codes from filters lower in
210 the filter chain. If a lower level filter returns an error, then
211 the request needs to stop immediately. This allows mod_include to
212 stop parsing data once a lower filter recognizes an error.
215 *) Add the ability to extend the methods that Apache understands
216 and have those methods <limit>able in the httpd.conf. It uses
217 the same bit mask/shifted offset as the original HTTP methods
218 such as M_GET or M_POST, but expands the total bits from an int to
219 an ap_int64_t to handle more bits for new request methods than
220 an int provides. [Cody Sherr <csherr@covalent.net>]
222 *) Fix broken mod_mime behavior in merging its arguments. Possible
223 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
225 *) Solve many mod_ssl porting issues (too many to detail) with
226 help from the whole team, but most notably [Ralf S. Engelschall,
227 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
228 Doug MacEachern, William Rowe, Cliff Woolley]
230 *) More stall fixes for the threaded & worker mpm's.
231 Make mod_status output more accurate. Don't
232 count workers in processes which aren't actively
233 serving requests. [Greg Ames]
235 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
237 *) Add a single listener/multiple worker MPM. This MPM is
238 definately not fully correct, but it allows us to solve many
239 of the problems that exist in the threaded MPM. This is a
240 modified version of the threaded MPM. [Ryan Bloom]
242 *) Improve content generation throughout Apache, providing closer
243 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
244 Transitional specifications. [William Rowe]
246 Changes with Apache 2.0.22
248 *) Fix a problem where the threaded MPM stalls after restarts or
249 segfaults. Also prevent multiple active processes from using
250 the same scoreboard slot. [Greg Ames]
252 *) Apache/Win32 now fills in the service description with Apache's
253 server version string, including loaded and advertised modules.
256 *) Improved support for the Win32 build, to recover gracefully from
257 missing apr or apr-util directories or the awk interpreter,
258 create the proper cgi-bin examples, including a test-cgi.bat, and
259 fix the perl shebang line for printenv.pl, when installing from
260 the build environment. [William Rowe]
262 *) Fix a segfault in threaded.c caused by passing uninitialized
263 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
265 *) Use new APR number conversion functions to reduce CPU consumption
266 when setting the content length, and in mod_log_config.
269 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
270 where HEAD response headers were being repeated twice for
271 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
272 problem in the http_header filter was exposed by the recent rewrite
273 of the content_length filter. [Taketo Kabe, Bill Stoddard]
275 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
276 restarts. A garbage pointer to a vhost's server_rec from the
277 previous generation was being left around under certain
278 conditions. [Greg Ames]
280 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
281 used to appear as '(none', without the closing paren.
282 [Günter Knauf <eflash@gmx.net>]
284 *) Improve the exports generating awk script. In the past, we had
285 work around problems in the awk script by avoiding some #if and
286 #ifdefs. This has bitten us many times in generating the exports.c
287 file. This improvement allows corrects the header file parsing.
288 [Sander Striker <striker@apache.org>]
290 Changes with Apache 2.0.21
292 *) Resolve the Win32 htpasswd bug, where a file that existed would be
293 overwritten, regardless of the -c flag.
294 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
296 *) Introduce connection sub-pools into ab. Truncating the lifetime
297 of these allocations means that ab no longer perpetually grows
298 its working set, running out of memory on large request attempts.
301 *) Make scoreboard creation a hook. This allows management
302 modules to have access to the scoreboard at the time that it is
303 created, and at every restart request.
304 [Cody Sherr <csherr@covalent.net>]
306 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
307 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
308 daemon index actually used in the scoreboard. I also
309 updated the pertinent calls. [Paul J. Reder]
311 *) Win32: Prevent listening sockets from being inherited by
312 the Apache child process, CGI scripts, rotatelog process
313 etc. If the Apache child process segfaults, any processes
314 that the child started are not reaped. Prior to this fix,
315 these processes inherited the listening sockets which sometimes
316 prevented the restarted Apache child process from accepting
317 connections (ie, the server would hang).
320 *) Provide vhost and request strings when ExtendedStatus is on.
323 *) Fix some issues with the pod and prefork: check the pod *after*
324 processing a connection so that a server processing a time-
325 consuming request bails out as soon as practical; when the
326 parent process wakes up a server process via connect(), use an
327 APR timeout on the connect() so that we don't hang for a long
328 time if there aren't server processes around to do accept().
329 [Jeff Trawick, Greg Ames]
331 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
332 spends a lot of time in apr_table_get calls. Using the default
333 httpd.conf, the tables for languages and charsets are somewhat
334 large, so the time spent scanning them on each request is
335 significant. Replacing the tables with hash tables provides
336 a nice speedup. [Brian Pane <bpane@pacbell.net>]
338 *) Add two functions to allow modules to access random parts of the
339 scoreboard. This allows modules compiled for one MPM to access the
340 scoreboard, even if it the server was compiled for another MPM.
341 [Harrie Hazewinkel <harrie@covalent.net>]
343 Changes with Apache 2.0.20
345 *) Fix problem in content-length filter where the filter would
346 buffer all the output from a CGI before sending any bytes
347 down the filter stack to the network. This problem would cause
348 significant memory consumption if the CGIs generated
349 lots of bytes. [Bill Stoddard]
351 *) Get non-blocking CGI pipe reads working with the bucket brigades.
354 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
357 *) Fix a bug in the threaded MPM that would cause it to kill off all
358 workers immediately after starting if the number of workers started
359 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
361 Changes with Apache 2.0.19
363 *) Fix problem with threaded MPM. The problem was that if each child
364 process was busy serving a single long-lived request and the server
365 was sent a graceful restart signal, the server would stop serving
366 requests. This would happen because each child process would wait to
367 die until the last thread was done, and the parent wouldn't spawn any
368 new children until a process died. Now, the parent looks at the fact
369 that the children are dying gracefully, and starts new children.
370 Those new children only start enough threads to compliment the number
371 of threads in the other child process that shares the same spot in
372 the scoreboard. In this way, we make sure to never go over
373 MaxClients. [Ryan Bloom]
375 *) modified mod_negotiation and mod_autoindex to speed up by almost a
376 factor of two on apr_dir_read()-enhanced platforms, such as Win32
377 and OS2, by calling ap_sub_request_lookup_dirent() with the results
378 already provided by apr_dir_read(). [William Rowe]
380 *) mod_file_cache is now more robust to filtering and serves requests
381 slightly more efficiently. [Cliff Woolley]
383 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
384 Module was calling ap_rwrite() followed by ap_rflush() but the
385 served content was not being displayed in the browser. Inspection
386 of the output stream revealed that the first data chunk was
387 missing the trailing CRLF required by the RFC. [Bill Stoddard]
389 *) apxs no longer generates ap_send_http_header() in the example handler
391 *) Fix an ab problem which could cause a divide-by-zero exception
392 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
393 [Ian Holsman <ianh@cnet.com>]
395 *) Solve case-insensitive platforms' confusion about negotiated
396 filenames, allowing files of differnt case to match in choosing
397 the document to serve. [William Rowe]
399 *) Fix brokenness when ThreadsPerChild is higher than the built-in
400 limit. We left ap_threads_per_child at the higher value which
401 led to segfaults when doing certain scoreboard operations.
404 *) Fix seg faults and/or missing output from mod_include. The
405 default_handler was using the subrequest pool for files and
406 MMAPs, even though the associated APR structures typically
407 live longer than the subrequest. [Greg Ames]
409 *) Extend mod_setenvif to support specifying regular expressions
410 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
411 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
412 will cause HAVE_TS to be set if any of the request headers begins
413 with "TS" and has a value that begins with any character in the
414 set [a-z]. [Bill Stoddard]
416 *) httpd children now re-bind themselves to a random CPU on
417 multiprocessor systems on AIX via bindprocessor() in 2.0.
418 [Victor J. Orlikowski]
420 *) Fix htdigest. It would go into a loop in getline when adding
421 a second user. [Bill Stoddard]
423 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
425 *) Automatically generate httpd.exp for AIX.
426 DSOs now work again on AIX in 2.0
427 [Victor J. Orlikowski]
429 *) Add a new request hook, error_log. This phase allows modules
430 to act on the error log string _after_ it has been written
431 to the error log. The goal for this hook is to allow monitoring
432 modules to send the error string to the monitoring agent.
435 *) Modify mod_echo to make it use filters for input and output.
436 [Ryan Morgan <rmorgan@covalent.net>]
438 *) Extend mod_headers to support conditional driven Header
439 add, append and set. Use SetEnvIf to set an envar and conditionally
440 add/append/set headers based on this envar thusly:
442 SetEnvIf TSMyHeader value HAVE_TSMyHeader
443 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
445 If the request contains header "TSMyHeader: value" then header
446 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
449 *) Extend mod_headers to support using format specifiers on Header
450 add, append and set header values. Two format specifiers are supported:
452 %t - reports, in UTC microseconds since the epoch, when the
453 request was received.
455 %D - reports the time, in microseconds, between when the request was
456 received and the response sent.
459 Header add MyHeader "This request served in %D microseconds. %t"
461 results in a header being added to the response that looks like this:
463 MyHeader: This request served in D=5438 microseconds. t=991424704447256
467 *) Fix reset_filter(). We need to be careful how we remove filters.
468 If we set r->output_filters to NULL, we also have to reset the
469 connection's filters. [John Sterling]
471 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
473 *) Add a check to ap_die() to make sure the filter stack is sane and
474 contains the correct basic filters when an error occurs. This fixes
475 a problem where headers are not being sent on error. [John Sterling]
477 *) New Header directive 'echo' option. "Header echo regex" will
478 cause any headers received on the request that match regex to be
479 echoed to (included in) the response headers.
482 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
483 This prevented the inclusion of apr_compat.h. PR #7773
484 [Oleg Broytmann <phd@phd.pp.ru>]
486 *) Moved util_uri to the apr-util library. This required a bunch of
487 apr_name changes for the uri utility functions. [Justin Erenkrantz]
489 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
490 insert_filter phase so that other filters are not bypassed by default.
493 *) Reimplement mod_headers as an output filter. mod_headers can now
494 add custom headers to inbound requests using the RequestHeader directive
495 and to responses using the same old Header directive. [Graham Leggett]
497 Changes with Apache 2.0.18
499 *) Fix command-line processing so that if a bad argument is specified
500 Apache will exit. [Jeff Trawick]
502 *) Change the make targets and rules to be consistent in all of the
503 Apache-owned source trees. [Roy Fielding]
505 *) Fix processing of the TRACE method. Previously we passed bogus
506 parms to form_header_field() and it overlaid some vhost structures,
507 resulting in a segfault in check_hostalias().
508 [Greg Ames, Jeff Trawick]
510 *) Win32: Add support for reliable piped logs. If the logging process
511 goes down, Apache will automatically restart it. This function has
512 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
515 *) Do not start piped log processes during the config file
516 preflight. This change also circumvents a problem on
517 Windows where the rotatelog processes created during preflight
518 was not getting cleaned up properly.
521 *) add "Request Phase Participation" info to mod_info
524 *) Make first phase changes to the scoreboard data structures in
525 preparation for the rewriting of the scoreboard per my posted
526 design notes. [Paul J. Reder]
528 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
529 and apr-util, allow it to be overridden by the configure command-line
530 (default="--silent") and introduce LT_LDFLAGS to replace what we were
531 formerly abusing as LTFLAGS. [Roy Fielding]
533 *) Clean up the reporting of incorrect closing container tags.
534 [Barrie Slaymaker <barries@slaysys.com>]
536 *) Simplify the configure process by moving all libtool stuff to APR
537 and moving hints.m4 inline. [Roy Fielding]
539 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
540 of functions used by mod_proxy for export in the DLL
541 [Ian Holsman <IanH@cnet.com>]
543 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
544 request body from its stdin but no reqest body is being written to
545 the cgi. [Jeff Trawick]
547 *) mod_log_config: %c connection status incorrectly logged
548 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
551 *) Get mod_cern_meta working under Windows
554 *) Create Files, and thus MMAPs, out of the request pool, not the
555 connection pool. This solves a small resource leak that had us
556 not closing files until a connection was closed. In order to do
557 this, at the end of the core_output_filter, we loop through the
558 brigade and convert any data we have into a single HEAP bucket
559 that we know will survive clearing the request_rec.
560 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
563 *) Completely revamp configure so that it preserves the standard make
564 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
565 the configure additions to EXTRA_* variables. Also, allow the user
566 to specify NOTEST_* values for all of the above, which eliminates the
567 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
568 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
569 avoid pointless duplications. Fix the order in which flags are given
570 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
571 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
572 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
573 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
575 *) Get mod_tls to compile/work better on Windows. PR #7612
576 [Bernhard Schrenk <b.schrenk@improx.com>]
578 *) Fix shutdown/restart hangs in the threaded MPM.
579 [Jeff Trawick, Greg Ames, Ryan Bloom]
581 *) Removed the keptalive boolean from conn_rec because it is now only
582 used by a single routine and can be replaced by a local variable.
583 [Greg Stein, Ryan Bloom, Roy Fielding]
585 *) Patch prefork to put enough of the signal processing back in so that
586 signals are all handled properly now. The previous patch fixed the
587 deadlock race condition, but broke the user directed signal handling.
588 This fixes it to work the way it did before my previous prefork patch
589 (primarily, SIGTERM is now working).
591 *) Change how input filters decide how much data is returned to the
592 higher filter. We used to use a field in the conn_rec, with this
593 change, we use an argument to ap_get_brigade to determine how much
594 data is retrieved. [Ryan Bloom]
596 *) Fix seg fault at start-up introduced by Ryan's change to enable
597 modules to specify their own logging tags. mod_log_config
598 registers an optional function, ap_register_log_handler().
599 ap_register_log_handler() was being called by http_core before
600 the directive hash table was created. This patch creates the
601 directive hash table before ap_register_log_handler() is
602 registered as an optional function.
603 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
605 *) Add ap_set_int_slot() function
606 [John K. Sterling <sterling@covalent.net>]
608 *) Under certain circumstances, Apache did not supply the
609 right response headers when requiring authentication.
610 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
611 (This is a port of the change that went into Apache 1.3.19.)
613 *) Allow modules to specify their own logging tags. This basically
614 allows a module to tell mod_log_config that when %x is encountered
615 a specific function should be called. Currently, x can be any single
616 character. It may be more useful to make this a string at some point.
619 Changes with Apache 2.0.17
621 *) If a higher-level filter handles the the byterange aspects of a
622 request, then the byterange filter should not try to redo the
623 work. The most common case of this happening, is a byterange
624 request going through the proxy, and the origin server handles
625 the byterange request. The proxy should ignore it.
626 [Graham Leggett <minfrin@sharp.fm>]
628 *) Changed the threaded mpm to have child_main join to each of the
629 worker threads to make sure the kids are all gone before child_main
630 exits after a signal (cleanup from perform_idle_server_maintenance).
631 This is an extension of Ryans recent commit to make the child_main
634 *) Add more options to the ap_mpm_query function. This also allows MPMs to
635 report if their threads are dynamic or static. Finally, this also
636 implements a new API, ap_show_mpm, which returns the MPM that was
637 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
639 *) Do not install the binaries from the support directory twice.
640 [jun-ichiro hagino <itojun@iijlab.net>]
642 *) The ap_f* functions should flush data to the filter that is passed
643 in, not the the filter after the one passed in.
644 [Ryan Morgan <rmorgan@covalent.net>]
646 *) Make ab work again by changing its native types to apr types and formats.
647 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
649 *) Move the byterange filter and all of the supporting functions back
650 to the HTTP module. The byterange filter turned out to be very
651 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
653 *) Make clean, distclean, and extraclean consistently according to the
654 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
656 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
657 This may have been causing problems stopping processes in the threaded
660 *) Fix content-length in mod_negotiation to a long int representation.
663 *) Remove BindAddress from the default config file.
664 [giles@nemeton.com.au]
666 *) Allow module authors to add a module to their Apache build using
667 --with-module, without re-running buildconf. The syntax is:
668 --with-module=module_type:/path/to/module.c
669 The configure script will copy the module.c file to
670 modules/module_type, and it will be added to the relevant Makefiles.
671 currently, this only works for static modules. [Ryan Bloom]
673 *) Changes required to make prefork clean up idle children properly.
674 There was a window during which a starting worker deadlocks when
675 an idle cleanup arrives before it completes init. Apache then keeps
676 trying to cleanup the same deadlocked worker forever (until higher
677 pids come along, but it still will never reduce below the deadlocked
678 pid). Thus the number of children would not reduce to the correct
679 idle level. [Paul J. Reder]
681 Changes with Apache 2.0.16
683 *) Change the default installation directory to /usr/local/apache2,
684 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
686 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
689 *) Get MaxRequestsPerChild working with the Windows MPM.
692 *) Make generic hooks to work, with mod_generic_hook_import/export
693 experimental modules. [Ben Laurie, Will Rowe]
695 *) Fix segfaults for configuration file syntax errors such as
696 "<Directory>" followed by "</Directory" and
697 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
699 *) Cleanup the --enable-layout option of configure. This makes
700 us use a consistent location for the config.layout file, and it
701 makes configure more portable.
702 [jun-ichiro hagino <itojun@iijlab.net>]
704 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
705 csv/gnuplot format, rudimentary ssl support and various other tweaks
706 to make results more true to what is measured. The upshot of this it
707 turns out that 'ab' has often underreported the true performance of
708 apache. Often by a order of magnitude :-) See talk/paper of Sander
709 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
710 [Dirk-Willem van Gulik]
712 *) Clean up mod_cgid's temporary request pool. Besides fixing a
713 storage leak this ensures that some unnecessary pipes are closed.
716 *) Performance: Add quick_handler hook. This hook is called at the
717 very beginning of the request processing before location_walk,
718 translate_name, etc. This hook is useful for URI keyed content
719 caches like Mike Abbott's Quick Shortcut Cache.
722 *) top_module global variable renamed to ap_top_module [Perl]
724 *) Move ap_set_last_modified to the core. This is a potentially
725 controversial change, because this is kind of HTTP specific. However
726 many protocols should be able to take advantage of this kind of
727 information. I expect that headers will need one more layer of
728 indirection for multi-protocol work, but this is a small step in
729 the right direction. [Ryan Bloom]
731 *) Enable mod_status by default. This matches what Apache 1.3 does.
734 *) Add a ScriptSock directive to the default config file. This is
735 only enabled when mod_cgid is used.
736 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
738 Changes with Apache 2.0.15
740 *) Untangled the buildconf script and eliminated the need for build's
741 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
742 libtool muck that is now under srclib/apr/build. [Roy Fielding]
744 *) Win32: Don't accept more connections than we have worker threads
748 *) Fix bug in the Unix threaded.c MPM that allowed child processes
749 to fork() new child processes.
752 *) Fix a major security problem with double-reverse lookup checking.
753 Previously, a client connecting over IPv4 would not be matched
754 properly when the server had an IPv6 listening socket. PR #7407
755 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
757 *) Change the way the beos MPM handles polling to allow it to stop and
758 restart. Problem was the sockets being polled were being reset by
759 the select call, so once it had accepted a connection it was no
760 longer listening on the UDP socket we use for shutdown instructions.
761 APR needs to be altered, patch on it's way. [David Reid]
763 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
764 on error exit from ap_getline(). Some other code got upset because
765 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
767 *) Handle ap_discard_request_body() being called more than once.
768 [Greg Ames, Jeff Trawick]
770 *) Get rid of an inadvertent close of file descriptor 2 in
771 mod_mime_magic. [Greg Ames, Jeff Trawick]
773 *) Add a hook, create_request. This hook allows modules to modify
774 a request while it is being created. This hook is called for all
775 request_rec's, main request, sub request, and internal redirect.
776 When this hook is called, the the r->main, r->prev, r->next
777 pointers have been set, so modules can determine what kind of
778 request this is. [Ryan Bloom]
780 *) Cleanup the build process a bit more. The Apache configure
781 script no longer creates its own helper scripts, it just
783 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
785 *) Stop the forced downgrade of the connection to HTTP/1.0 for
786 proxy requests. [Graham Leggett]
788 *) Avoid using sscanf to determine the HTTP protocol number in
789 the common case because sscanf is a performance hog. From
790 Mike Abbot's Accelerating Apache patch number 6.
791 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
793 *) Fix a security exposure in mod_access. Previously when IPv6
794 listening sockets were used, allow/deny-from-IPv4-address rules
795 were not evaluated properly (PR #7407). Also, add the ability to
796 specify IPv6 address strings with optional prefix length on Allow
797 and Deny. [Jeff Trawick]
799 *) Enhance rotatelogs so that a UTC offset can be specified, and
800 the logfile name can be formatted using strftime(3). (Brought
801 forward from 1.3.) [Ken Coar]
803 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
804 DuplicateHandle on an IOCompletionPort (a practice which
805 MS "discourages"). The new model does not rely on associating
806 the completion port with the listening sockets, thus the
807 completion port can be completely managed within the child
808 process. A dedicated thread accepts connections off the network,
809 then calls PostQueuedCompletionStatus() to wake up worker
810 threads blocked on the completion port.
813 *) Bring forward the --suexec-umask option which allows the
814 builder to preset the umask for suexec processes. [Ken Coar]
816 *) Add a -V flag to suexec, which causes it to display the
817 compile-time settings with which it was built. (Only
818 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
820 *) Mod_include should always unset the content-length if the file is
821 going to be passed through send_parsed_content. There is no to
822 determine if the content will change before actually scanning the
823 entire content. It is far safer to just remove the C-L as long
824 as we are scanning it. [Ryan Bloom]
826 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
827 request and not Proxy-Authenticate.
828 [Graham Leggett <minfrin@sharp.fm>]
830 Changes with Apache 2.0.14
832 *) Fix content-length computation. We ONLY compute a content-length if
833 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
834 or we already have all the data. [Ryan Bloom]
836 *) Report unbounded containers in the config file. Previously, a typo
837 in the </container> directive could result in the rest of the config
838 file being silently ignored, with undesired defaults used.
841 *) Make the old_write filter use the ap_f* functions for the buffering.
844 *) Move more code from the http module into the core server. This
845 is core code, basically the default handler, the default input
846 and output filters, and all of the core configuration directives.
847 All of this code is required in order for the server to work, with or
848 without HTTP. The server is closer to working without the HTTP
849 module, although there is still more to do. [Ryan Bloom]
851 *) Fix a number of SGI compile warnings throughout the server. Fix some
852 bad parameters to apr_bucket_read(). Fix a bad statement in
853 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
854 consistently; we were mixing apr_time_t and time_t in invalid ways
855 before. In load_file(), call apr_dso_error() instead of
856 apr_strerror() so that we get a more specific string on some platforms.
857 PR #6980 [Jeff Trawick]
859 *) Allow modules to query the MPM about it's execution profile. This
860 query API can and should be extended in the future, but for now,
861 max_daemons, and threading or forking is a very good start.
862 [Jon Travis <jtravis@covalent.net>]
864 *) Modify mod_include to send blocks of data no larger than 9k.
865 Without this, mod_include will wait until the whole file is parsed,
866 or the first tag is found to send any data to the client.
867 [Paul J. Reder <rederpj@raleigh.ibm.com>]
869 *) Fix mod_info, so that <Directory> and <Location> directives are
870 not displayed twice when displaying the current configuration.
871 [Ryan Morgan <rmorgan@covalent.net>]
873 *) Add config directives to override DEFAULT_ERROR_MSG and
874 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
875 [Dan Rench <drench@xnet.com>]
877 *) Get mod_info building and loading on Win32. [William Rowe]
879 *) Begin to move protocol independant functions out of mod_http. The goal
880 is to have only functions that are HTTP specific in the http directory.
883 Changes with Apache 2.0.13
885 *) Don't assume that there will always be multiple calls to the byterange
886 filter. It is possible that we will need to do byteranges with only
887 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
889 *) Move the error_bucket definition from the http module to the
890 core server. Every protocol will need this ability, not just
893 Changes with Apache 2.0.12
895 *) Modify mod_file_cache to save pre-formatted strings for
896 content-length and last-modified headers for performance.
897 [Mike Abbot <mja@trudge.engr.sgi.com>]
899 *) Namespace protect IOBUFSIZ since it is exposed in the API.
900 [Jon Travis <jtravis@covalent.net>]
902 *) Use "Basic" authentication instead of "basic" in ab, as the spec
903 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
905 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
906 without ever filling it out. This fixes PR 7271.
907 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
908 Cliff Woolley <cliffwoolley@yahoo.com>]
910 *) Add a couple of GCC attribute tags to printf style functions.
911 [Jon Travis <jtravis@covalent.net>]
913 *) Add the correct language tag for interoperation with the Taiwanese
914 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
916 *) Migrate the perchild MPM to use the new apr signal child, and
917 APR thread functions. [Ryan Bloom]
919 *) Close one copy of the CGI's stdout before creating the new process.
920 The CGI will still have stdout, because we have already dup'ed it.
921 This keeps Apache from waiting forever to send the results of a CGI
922 process that has forked a long-lived child process.
923 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
925 *) Remove the rest of the pthreads functions from the threaded MPM.
926 This requires the APR support for a signal thread that was just
929 *) Make mod_dir use a fixup for sending a redirect to the browser.
930 Before this, we were using a handler, which doesn't make much
931 sense, because the handler wasn't generating any data, it would
932 either return a redirect error code, or DECLINED. This fits the
933 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
935 *) Make the threaded MPM use APR threads instead of pthreads.
938 *) Get mod_tls to the point where it actually appears to work in all cases.
941 *) implement --enable-modules and --enable-mods-shared for "all" and
944 *) Move the threaded MPM to use APR locks instead of pthread locks.
947 *) Rename mpmt_pthread to threaded. This is more in line with the
948 fact that mpmt_pthread shouldn't be using pthreads directly, and
949 it is a smaller name that doesn't tie into anything.
952 *) Rename the module structures so that the exported symbol matches
953 the file name, and it is easier to automate the installation
954 process (generating LoadModule directives from the module filenames).
957 *) Remove the coalesce filter. With the ap_f* functions, this filter
958 is no longer needed. [Ryan Bloom]
960 Changes with Apache 2.0.11
962 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
963 added feature of allowing a uid/gid per child process. If no
964 uid/gid is specified, then Perchild behaves exactly like dexter.
967 *) Get perchild building again. [Ryan Bloom]
969 *) Don't disable threads just because we are using the prefork MPM.
970 If somebody wants to compile without threads, they must now add
971 --disable-threads to the configure command line. [Ryan Bloom]
973 *) Begin to move the calls to update_child_status into common code, so
974 that each individual MPM does not need to update the scoreboard itself.
977 *) Allow mod_tls to compile under Unix boxes where openssl has been
978 installed to the system include files.
979 [Gomez Henri <new-httpd@slib.fr>]
981 *) Cleanup the mod_tls configure process. This should remove any need
982 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
983 configure doesn't check that yet. [Ryan Bloom]
985 *) Add a very early prototype of SSL support (in mod_tls.c). It is
986 vital that you read modules/tls/README before attempting to build
989 *) Fix a potential seg fault on all platforms. David Reid fixed this
990 on BEOS, but the problem could happen anywhere, so we don't want
991 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
993 *) Add new LogFormat directive, %D, to log time it takes to serve a
994 request in microseconds. [Bill Stoddard]
996 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
997 SetOutputFilter. This corresponds nicely with the other Set
998 directives, which operate on containers while the Add* directives
999 tend to work directly on extensions. [Ryan Bloom]
1001 *) Cleanup the header handling a bit. This uses the apr_brigade_*
1002 functions for the buffering so that we don't need to compute
1003 the length of the headers before we actually create the header
1004 buffer. [Ryan Bloom]
1006 *) Allow filters to buffer data using the ap_f* functions. These have
1007 become macros that resolve directly to apr_brigade_*.
1010 *) Get the Unix MPM's to do a graceful restart again. If we are going
1011 to register a cleanup with ap_cleanup_scoreboard, then we have to
1012 kill the cleanup with the same function, and that function can't be
1013 static. [Ryan Bloom]
1015 *) Install all required header files. Without these, it was not
1016 possible to compile some modules outside of the server.
1019 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
1020 forward from 1.3 to 2.0, we missed a single line, which broke regex
1021 aliases. [Ryan Bloom]
1023 *) We have a poor abstraction in the protocol. This is a temporary
1024 hack to fix the bug, but it will need to be fixed for real. If
1025 we find an error while sending out a custom error response, we back
1026 up to the first non-OK request and send the data. Then, when we send
1027 the EOS from finalize_request_protocol, we go to the last request,
1028 to ensure that we aren't sending an EOS to a request that has already
1029 received one. Because the data is sent on a different request than
1030 the EOS, the error text never gets sent down the filter stack. This
1031 fixes the problem by finding the last request, and sending the data
1032 with that request. [Ryan Bloom]
1034 *) Make the server status page show the correct restart time, and
1035 thus the proper uptime. [Ryan Bloom]
1037 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1038 should reduce the amount of duplicate code that is required to
1039 create CGI processes.
1040 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1042 *) ap_new_connection() closes the socket and returns NULL if a socket
1043 call fails. Usually this is due to a connection which has been
1044 reset. [Jeff Trawick]
1046 *) Move the Apache version information out of httpd.h and into release.h.
1047 This is in preparation for the first tag with the new tag and release
1048 system. [Ryan Bloom]
1050 *) Begin restructuring scoreboard code to enable adding back in
1051 the ability to use IPC other than shared memory.
1052 Get mod_status working on Windows again. [Bill Stoddard]
1054 *) Make mod_status work with 2.0. This will work for prefork,
1055 mpmt_pthread, and dexter. [Ryan Bloom]
1057 *) Correct a typo in httpd.conf.
1058 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1060 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1062 *) Get the correct IP address if ServerName isn't set and we can't
1063 find a fully-qualified domain name at startup.
1064 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1066 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1068 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1069 'extra' stat's for user/group since they should never occur, and now
1070 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1071 volumes. [William Rowe]
1073 *) Adopt apr features to simplify mod_includes. This changes the
1074 behavior of the USER_NAME variable, unknown uid's are now reported
1075 as USER_NAME="<unknown>" rather than the old user#000 result.
1076 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1078 *) Adopt apr features for simplifing mod_userdir, and accept the new
1079 Win32/OS2 exceptions without hiccuping. [William Rowe]
1081 *) Replace configure --with-optim option by using and saving the
1082 environment variable OPTIM instead. This is needed because configure
1083 options do not support multiple flags separated by spaces.
1086 *) Fix some byterange handling. If we get a byte range that looks like
1087 "-999999" where that is past the end of the file, we should return
1088 a PARTIAL CONTENT status code, and return the whole file as one big
1089 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1091 *) Make the error bucket a real meta-data bucket. This means that the
1092 bucket length is 0, and a read returns NULL data. If one of these
1093 buckets is passed down after the headers are sent, this data will
1094 just be ignored. [Greg Stein]
1096 *) The prefork MPM wasn't killing child processes correctly if a restart
1097 signal was received while the process was serving a request. The child
1098 process would become the equivalent of a second parent process. If
1099 we break out of the accept loop, then we need to do die after cleaning
1100 up after ourselves. [Ryan Bloom]
1102 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1103 restarts. [Ryan Bloom]
1105 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1106 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1107 performing very expensive owner, group and permission lookups
1108 and allows the server to function until these apr_finfo_t fields
1109 are implemented under Win32. [William Rowe]
1111 *) Support for typedsafe optional functions - that is functions exported by
1112 optional modules, which, therefore, may or may not be present, depending
1113 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1114 for sample code. [Ben Laurie]
1116 *) filters can now report an HTTP error to the server. This is done
1117 by sending a brigade where the first bucket is an error_bucket.
1118 This bucket is a simple bucket that stores an HTTP error and
1119 a string. Currently the string is not used, but it may be needed
1120 to output an error log. The http_header_filter will find this
1121 bucket, and output the error text, and then return
1122 AP_FILTER_ERROR, which informs the server that the error web page
1123 has already been sent. [Ryan Bloom]
1125 *) If we get an error, then we should remove all filters except for
1126 those critical to serving a web page. This fixes a bug, where
1127 error pages were going through the byterange filter, even though
1128 that made no sense. [Ryan Bloom]
1130 *) Relax the syntax checking of Host: headers in order to support
1131 iDNS. PR#6635 [Tony Finch]
1133 *) Cleanup the byterange filter to use the apr_brigade_partition
1134 and apr_bucket_copy functions. This removes a lot of very messy
1135 code, and hopefully makes this filter more stable.
1138 *) Remove AddModule and ClearModuleList directives. Both of these
1139 directives were used to ensure that modules could be enabled
1140 in the correct order. That requirement is now gone, because
1141 we use hooks to ensure that modules are in the correct order.
1144 *) When SuExec is specified, we need to add it to the list of
1145 targets to be built. If we don't, then any changes to the
1146 configuration won't affect SuExec, unless 'make suexec' is
1147 specifically run. [Ryan Bloom]
1149 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1150 the APR_XTHREAD argument to open a file for consumption by
1151 parallel threads on win32. [William Rowe]
1153 *) Correct a bug in determining when we follow symlinks. The code
1154 expected a stat -1 result, not an apr_status_t positive error.
1155 Also check if the APR_FINFO_USER fields are valid before we
1156 follow the link. [William Rowe]
1158 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1159 mpm_common.c. These functions are only valid on some platforms,
1160 so they should not be in the main-line code. [Ryan Bloom]
1162 *) Remove ap_chdir_file(). This function is not thread-safe,
1163 and nobody is currently using it. [Ryan Bloom]
1165 *) Do not try to run make depend if there are no .c files in the
1166 current directory, doing so makes `make depend` fail.
1169 *) Update highperformance.conf to work with either prefork or
1170 pthreads mpms. [Greg Ames]
1172 *) Stop checking to see if this is a pipelined request if we know
1173 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1174 This keeps us from making an extra read call when serving a 1.0
1175 request. [Ryan Bloom and Greg Stein]
1177 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1178 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1179 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1181 *) Fix the RFC number mentioned when complaining about a missing
1182 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1184 *) Fix an endless loop in ab which occurred when ab was posting
1185 and the server dropped the connection unexpectedly.
1188 *) Fix a segfault while handling request bodies in ap_http_filter().
1189 This problem has been seen with mod_dav usage as well as with
1190 requests where the body was just being discarded. [Jeff Trawick]
1192 *) Some adjustment on the handling and automatic setting (via
1193 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1194 add the capability to specify flags (NOTEST_CFLAGS and
1195 NOTEST_LDFLAGS) which are used to compile Apache, but
1196 not used during the configuration process. Useful for
1197 flags like "-Werror". [Jim Jagielski]
1199 *) Stop using environment variables to force debug mode or
1200 no detach. We now use the -D command line argument to
1201 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1202 [Greg Stein, Ryan Bloom]
1204 *) Change handlers to use hooks. [Ben Laurie]
1206 *) Stop returning copies of filenames from both apr_file_t and
1207 apr_dir_t. We pstrdup the filenames that we store in the
1208 actual structures, so we don't need to pstrdup the strings again.
1211 *) mod_cgi: Fix some problems where the wrong error value was being
1212 traced. [Jeff Trawick]
1214 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1217 *) Add generic hooks. [Ben Laurie]
1219 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1221 *) Fix a segfault caused by mod_ext_filter when the external filter
1222 program does not exist. [Jeff Trawick]
1224 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1225 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1226 was served through mod_charset_lite (or anything else that would
1227 create a transient bucket in this size range). ap_bucket_make_heap()
1228 silently failed (fixed), transient_setaside() discovered it, but
1229 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1231 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1232 is that some browsers send extra lines at the end of POST requests, and
1233 we don't want to delay sending data back to the user just because the
1234 browser isn't well behaved. [Ryan Bloom]
1236 *) Get SuEXEC working again. We can't send absolute paths to suExec
1237 because it refuses to execute those programs. SuEXEC also wasn't
1238 always recognizing configuration changes made using the autoconf
1241 *) Allow the buildconf process to find the config.m4 files in the correct
1242 order. Basically, we can now name config.m4 files as config\d\d.m4,
1243 and we will sort them correctly when inserting them into the build
1244 process. [Ryan Bloom]
1246 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1247 This also allows mod_cgid to use ap_os_create_priviledged_process,
1248 thus allowing for SuExec execution from mod_cgid. Currently, we do
1249 not support everything that standard SuExec supports, but at least
1250 it works minimally now. [Ryan Bloom]
1252 *) Allow SuExec to be configured from the ./configure command line.
1255 *) Update some of the docs in README and INSTALL to reflect some of
1256 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1258 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1259 need to call sendfile again. This gets us serving large files
1260 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1262 *) Get the support programs building cleanly again.
1263 [Cliff Woolley <cliffwoolley@yahoo.com>]
1265 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1266 current directory logic now backs up over bin/ to determine the
1267 server root from the Apache.exe path.
1269 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1270 loadable modules, dynamic libs are all named libfoo.dll, and the
1271 makefile.win populates the include, lib and libexec directories.
1273 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1274 Apache gets IPv6 listening sockets by default. Additionally, the
1275 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1276 numeric address strings (e.g., "Listen [fe80::1]:8080").
1279 *) Modify the install directory layout. Modules are now installed in
1280 modules/. Shared libraries should be installed in libraries/, but
1281 we don't have any of those on Unix yet. All install directories
1282 are modifyable at configure time. [Ryan Bloom]
1284 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1286 *) Get the functions in server/linked into the server, regardless of
1287 which modules linked into the server. This uses the same hack
1288 for Apache that we use for APR and apr-util to ensure all of the
1289 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1290 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1291 the scripts a bit easier.
1294 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1295 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1297 *) Get all of the auth modules to the point that they will install and
1298 be loadable into the server. Our new build/install mechanism expects
1299 that all modules will have a common name format. The auth modules
1300 didn't use that format, so we didn't install them properly.
1303 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1304 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1306 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1308 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1309 after the end of the response. [Ryan Bloom]
1311 *) Get byterange requests working with responses that do not have a
1312 content-length. Because of the way byterange requests work, we have to
1313 have all of the data before we can actually do the byterange, so we
1314 can compute the content-length in the byterange filter.
1317 *) Get exe CGI's working again on Windows.
1320 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1321 they keep track of whether or not their post config hook has been
1322 called before. Instead of a static variable (which is replaced when
1323 the DSO is loaded a second time), use userdata in the process pool.
1326 Changes with Apache 2.0a9
1328 *) Win32 now requires perl to complete the final install step for users
1329 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1330 and installs the conf, htdocs and htdocs/manual directories.
1333 *) Make mod_include use a hash table to associate directive tags with
1334 functions. This allows modules to implement their own SSI tags easily.
1335 The idea is simple enough, a module can insert it's own tag and function
1336 combination into a hash table provided by mod_include. While mod_include
1337 parses an SSI file, when it encounters a tag in the file, it does a
1338 hash lookup to find the function that implements that tag, and passes
1339 all of the relevant data to the function. That function is then
1340 responsible for processing the tag and handing the remaining data back
1341 to mod_include for further processing.
1342 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1344 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1345 fewer parameters: the local and remote socket addresses were removed
1346 from the parameter list because all required information is available
1347 via the APR socket. [Jeff Trawick]
1349 *) Distribution directory structure reorganized to reflect a
1350 normal source distribution with external install targets.
1353 *) The MPMs that need multiple segments of shared memory now create
1354 two apr_shmem_t variables, one for each shared memory allocation.
1355 the problem is that we can't determine how much memory will be required
1356 for shared memory allocations once we try to allocate more than one
1357 variable. The MM code automatically aligns the shared memory allocations,
1358 so we end up needing to pad the amount of shared memory we want based
1359 on how many variables will be allocated out of the shared memory segment.
1360 It is just easier to create a second apr_shmem_t variable, and two
1361 shmem memory blocks.
1364 *) Cleanup the export list a bit. This creates a single unified list of
1365 functions exported by APR. The export list is generated at configure
1366 time, and that list is then used to generate the exports.c file.
1367 Because of the way the export list is generated, we only export those
1368 functions that are valid on the platform we are building on.
1371 *) Enable logging the cookie with mod_log_config
1372 [Sander van Zoest <sander@covalent.net>]
1374 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1377 *) Added lib/aputil/ as a placeholder for utility functions which are not
1378 specific to the Apache HTTP Server (but do not make sense with APR).
1379 The first utility is "apu_dbm": a set of functions to work with DBM
1380 files. This first version can be compiled for SDBM or GDBM databases.
1383 *) Complete re-write of mod_include. This makes mod_include a filter that
1384 uses buckets directly. This has now served the FAQ correctly.
1385 [Paul Reder <rederpj@raleigh.ibm.com>]
1387 *) Allow modules to specify the first filter in a sub_request when
1388 making the sub_request. This keeps modules from having to change the
1389 output_filter immediately after creating the sub-request, and therefore
1390 skip the sub_req_output_filter. [Ryan Bloom]
1392 *) Update ab to accept URLs with IPv6 literal address strings (in the
1393 format described in RFC 2732), and to build Host header fields in
1394 the same format. This allows IPv6 literal address strings to be
1395 used with ab. This support has been tested against Apache 1.3 with
1396 the KAME patch, but Apache 2.0 does not yet work with this format
1397 of the Host header field. [Jeff Trawick]
1399 *) Accomodate an out-of-space condition in the piped logs and the
1400 rotatelogs.c code, and no longer churn log processes for this
1401 condition. [Victor J. Orlikowski]
1403 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1406 Changes with Apache 2.0a8
1408 *) Add a directive to mod_mime so that filters can be associated with
1412 *) Get multi-views working again. We were setting the path_info
1413 field incorrectly if we couldn't find the specified file.
1416 *) Fix 304 processing. The core should never try to send the headers
1417 down the filter stack. Always, just setup the table in the request
1418 record, and let the header filter convert it to data that is ready
1422 *) More fixes for the proxy. There are still bugs in the proxy code,
1423 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1427 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1430 *) APR: Add new apr_getopt_long function to handle long options.
1431 [B. W. Fitzpatrick <fitz@red-bean.com>]
1433 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1434 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1435 hostname resolution/address string parsing and building
1436 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1437 of one of the apr_sockaddr_t structures for a socket. Change
1438 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1440 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1441 I have proxied pages with it, cleanup will commence soon.
1444 *) Make the proxy work with filters. This isn't perfect, because we
1445 aren't dealing with the headers properly. [Ryan Bloom]
1447 *) Do not send a content-length iff the C-L is 0 and this is a head
1448 request. [Ryan Bloom]
1450 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1451 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1453 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1455 *) Get the default_handler to stop trying to deal with HEAD requests.
1456 The idea is to let the content-length filter compute the C-L before
1457 we try to send the data. If we can get the C-L correctly, then we
1458 should send it in the HEAD response.
1461 *) The Header filter can now determine if a body should be sent based
1462 on r->header_only. The general idea of this is that if we delay
1463 deciding to send the body, then we might be able to compute the
1464 content-length correctly, which will help caching proxies to cache
1465 our data better. Any handler that doesn't want to try to compute
1466 the content-length can just send an EOS bucket without data and
1467 everything will just work.
1470 *) Add the referer to the error log if one is available.
1471 [Markus Gyger <mgyger@itr.ch>]
1473 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1474 change, the root of the configuration tree has been exposed to modules
1476 [Ryan Morgan <rmorgan@covalent.net>]
1478 *) Get the core_output_filter to use the bucket interface directly.
1479 This keeps us from calling the content-length filter multiple times
1480 for a simple static request.
1483 *) We are sending the content-type correctly now.
1484 [Ryan Bloom and Will Rowe]
1486 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1487 a bogus bytes-sent value when the only thing being sent was trailers
1488 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1490 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1491 hints file to determine which platforms define
1492 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1495 *) APR: add apr_get_home_directory() [Jeff Trawick]
1497 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1499 *) Not all platforms have INADDR_NONE defined by default. Apache
1500 used to make this check and define INADDR_NONE if appropriate,
1501 but APR needs the check too, and I suspect other applications will
1502 as well. APR now defines APR_INADDR_NONE, which is always a valid
1503 value on all platforms.
1504 [Branko Èibej <brane@xbc.nu>]
1506 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1507 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1509 *) Relax the syntax checking of Host: headers in order to support
1510 iDNS. PR#6635 [Tony Finch]
1512 *) When reading from file buckets we convert to an MMAP if it makes
1513 sense. This also simplifies the default handler because the
1514 default handler no longer needs to try to create MMAPs.
1517 *) BUFF has been removed from the main server. The BUFF code will remain
1518 in the code until it has been purged from the proxy module as well.
1521 *) Byteranges have been completely re-written to be a filter. This
1522 has been tested, and I believe it is working correctly, but it could
1523 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1524 the output from 1.3, the only difference being that 1.3 includes
1525 a content-length in the response, and this does not.
1528 *) APR read/write functions and bucket read functions now operate
1529 on unsigned integers, instead of signed ones. It doesn't make
1530 any sense to use signed ints, because we return the error codes,
1531 so if we have an error we should report 0 bytes read or written.
1534 *) Always compute the content length, whether it is sent or not.
1535 The reason for this, is that it allows us to correctly report
1536 the bytes_sent when logging the request. This also simplifies
1537 content-length filter a bit, and fixes the actual byte-reporing
1538 code in mod_log_config.c
1541 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1542 it says, because it was only used by EOS and FLUSH buckets. Since
1543 neither of those are required at the end of a brigade, this was
1544 really signifying FLUSH_THE_DATA, but that can be determined better
1545 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1546 buckets now return a length of 0, which is actually the amount of data
1547 read, so they make more sense.
1550 *) Allow the core_output_filter to save some data past the end of a
1551 request. If we get an EOS bucket, we only send the data if it
1552 makes sense to send it. This allows us to pipeline request
1553 responses. As a part of this, we also need to allocate mmap
1554 buckets out of the connection pool, not the request pool. This
1555 allows the mmap to outlive the request.
1558 *) Make blocking and non-blocking bucket reads work correctly for
1559 sockets and pipes. These are the only bucket types that should
1560 have non-blocking reads, because the other bucket types should
1561 ALWAYS be able to return something immediately.
1564 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1565 server, but use Ctrl+Break to initiate a graceful restart
1566 instead of duplicating behavior. [John Sterling]
1568 *) Patch mod_autoindex to set the Last-Modified header based on
1569 the directory's mtime, and add the ETag header. [William Rowe]
1571 *) Merge the 1.3 patch to add support for logging query string in
1572 such a way that "%m %U%q %H" is the same as "%r".
1575 *) Port three log methods from mod_log_config 1.3 to 2.0:
1576 CLF compliant '-' byte count, method and protocol.
1579 *) Add a new LogFormat directive, %c, that will log connection
1580 status at the end of the response as follows:
1581 'X' - connection aborted before the response completed.
1582 '+' - connection may be kept-alive by the server.
1583 '-' - connection will be closed by the server.
1586 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1587 Unicode file names and paths for Win32, and tag the Content-Type
1588 from mod_autoindex to reflect that charset if the the feature
1589 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1591 *) Compute the content length (and add appropriate header field) for
1592 the response when no content length is available and we can't use
1593 chunked encoding. [Jeff Trawick]
1595 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1596 so that content input filters get dechunked data when using
1597 the default handler. Also removed REQUEST_CHUNKED_PASS.
1600 *) Add mod_ext_filter as an experimental module. This module allows
1601 the administrator to use external programs as filters. Currently,
1602 only filtering of output is supported. [Jeff Trawick]
1604 *) Most Apache functions work on EBCDIC machines again, as protocol
1605 data is now translated (again). [Jeff Trawick]
1607 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1608 the EBCDIC support. They are noops on ASCII machines, so this
1609 type of translation doesn't have to be surrounded by #ifdef
1610 CHARSET_EBCDIC. [Jeff Trawick]
1612 *) Fix mod_include. tag commands work again, and the server will
1613 send the FAQ again. This also allows mod_include to set aside
1614 buckets that include partial buckets.
1615 [Ryan Bloom and David Reid]
1617 *) Add suexec support back. [Manoj Kasichainula]
1619 *) Lingering close now uses the socket directly instead of using
1620 BUFF. This has been tested, but since all we can tell is that it
1621 doesn't fail, this needs to be really hacked on.
1624 *) Allow filters to modify headers and have those headers be sent to
1625 the client. The idea is that we have an http_header filter that
1626 actually sends the headers to the network. This removes the need
1627 for the BUFF to send headers.
1630 *) Charset translation: mod_charset_lite handles translation of
1631 request bodies. Get rid of the xlate version of ap_md5_digest()
1632 since we don't compute digests of filtered (e.g., translated)
1633 response bodies this way anymore. (Note that we don't do it at
1634 all at the present; somebody needs to write a filter to do so.)
1637 *) Input filters and ap_get_brigade() now have a input mode parameter
1638 (blocking, non-blocking, peek) instead of a length parameter.
1641 *) Update the mime.types file to the registered media types as
1642 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1645 *) Namespace protect some macros declared in ap_config.h
1648 *) Support HTTP header line folding with input filtering.
1651 *) Mod_include works again. This should still be re-written, but at
1652 least now we can serve an SHTML page again.
1655 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1656 to both the BUFF and the socket in the conn_rec. Functions that
1657 want to use the BUFF can, functions that want to use the socket,
1658 can. They point to the same place.
1661 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1662 [Tomas "Ögren" <stric@ing.umu.se>]
1664 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1665 associated pool goes away. (APR pipes on OS/2 were already had this
1666 logic.) This resolvs a fatal file descriptor leak with CGIs.
1669 *) The final line of the config file was not being read if there was
1670 no \n at the end of it. This was caused by apr_fgets returning
1671 APR_EOF even though we had read valid data. This is solved by
1672 making cfg_getline check the buff that was returned from apr_fgets.
1673 If apr_fgets return APR_EOF, but there was data in the buf, then we
1674 return the buf, otherwise we return NULL.
1677 *) Piped logs work again in the 2.0 series.
1680 *) Restore functionality broken by the mod_rewrite security fix:
1681 rewrite map lookup keys and default values are now expanded
1682 so that the lookup can depend on the requested URI etc.
1683 PR #6671 [Tony Finch]
1685 *) Tighten up the syntax checking of Host: headers to fix a
1686 security bug in some mass virtual hosting configurations
1687 that can allow a remote attacker to retrieve some files
1688 on the system that should be inaccessible. [Tony Finch]
1690 *) Add a pool bucket type. This bucket is used for data allocated out
1691 of a pool. If the pool is cleaned before the bucket is destroyed, then
1692 the data is converted to a heap bucket, allowing it to survive the
1696 *) Add a flush bucket. This allows modules to signal that the filters
1697 should all flush whatever data they currently have. There is no way
1698 to actually force them to do this, so if a filter ignores this bucket,
1699 that's life, but at least we can try with this.
1702 *) Add an output filter for sub-requests. This filter just strips the
1703 EOS bucket so that we don't confuse the main request's core output
1704 filter by sending multiple EOS buckets. This change also makes sub
1705 requests start to send EOS buckets when they are finished.
1708 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1709 makes ap_bucket_destroy a return void, which is okay because it
1710 used to always return APR_SUCCESS, and nobody ever checked its
1711 return value anyway.
1712 [Cliff Woolley <cliffwoolley@yahoo.com>]
1714 *) Remove the index into the bucket-type table from the buckets
1715 structure. This has now been replaced with a pointer to the
1716 bucket_type. Also add some macros to test the bucket-type.
1719 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1720 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1721 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1722 All _VAR_ flavors changes to _DATA to be absolutely clear.
1725 *) Add support for /, //, //servername and //server/sharename
1726 parsing of <Directory> blocks under Win32 and OS2.
1727 [Tim Costello, William Rowe, Brian Harvard]
1729 *) Remove the function pointers from the ap_bucket type. They have been
1730 replaced with a global table. Modules are allowed to register bucket
1731 types and use then use those buckets.
1734 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1735 once we finish writing the request body to the cgi child process;
1736 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1737 worked without this change (for reasons I don't understand), but large
1738 ones didn't. [Jeff Trawick]
1740 *) Remove file bucket specific information from the ap_bucket type.
1741 This has been moved to a file_bucket specific type that hangs off
1742 the data pointer in the ap_bucket type.
1745 *) Input filtering now has a third argument. This is the amount of data
1746 to read from lower filters. This argument can be -1, 0, or a positive
1747 number. -1 means give me all the data you have, I'll deal with it and
1748 let you know if I need more. 0 means give me one line and one line
1749 only. A positive number means I want no more than this much data.
1751 Currently, only 0 and a positive number are implemented. This allows
1752 us to remove the remaining field from the conn_rec structure, which
1756 *) Big cleanup of the input filtering. The goal is that http_filter
1757 understands two conditions, headers and body. It knows where it is
1758 based on c->remaining. If c->remaining is 0, then we are in headers,
1759 and http_filter returns a line at a time. If it is not 0, then we are
1760 in body, and http_filter returns raw data, but only up to c->remaining
1761 bytes. It can return less, but never more.
1762 [Greg Ames, Ryan Bloom, Jeff Trawick]
1764 *) mod_cgi: Write all of the request body to the child, not just what
1765 the kernel would accept on the first write. [Jeff Trawick]
1767 *) Back out the change that moved the brigade from the core_output_filters
1768 ctx to the conn_rec. Since all requests over a given connection
1769 go through the same core_output_filter, the ctx pointer has the
1773 *) Fix another bug in the send_the_file() read/write loop. A partial
1774 send by apr_send would cause unsent data in the read buffer to
1775 get clobbered. Complete making send_the_file handle partial
1776 writes to the network.
1779 *) Fix a couple of type fixes to allow compilation on AIX again
1780 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1782 *) Fix bug in send_the_file() which causes offset to be ignored
1783 if there are no headers to send.
1786 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1787 filter. Useful for supporting Windows 9* with a binary
1788 compiled on Windows NT.
1791 Changes with Apache 2.0a7
1793 *) Reimplement core_output_filter to buffer/save bucket brigades
1794 across multiple calls to the core_filter. The brigade will be
1795 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1796 thresholds are hit or the EOS bucket is received.
1799 *) Create experimental filter (buffer_filter) that coalesces bytes
1800 into one large buffer before invoking the next filter in the
1801 chain. This filter is particularly useful with the current
1802 implementation of mod_autoindex when it inserted above the
1803 chunk_filter. mod_autoindex generates a lot of brigades that
1804 containing buckets holding just a few bytes each. The
1805 buffer_filter coalesces these buckets into a single large bucket.
1808 *) Add apr_sendfile() support into the core_output_filter.
1811 *) Add apr_sendv() support into the core_output_filter.
1814 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1815 [Mike Abbott <mja@sgi.com>]
1817 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1818 make much sense, because Apache uses buckets instead of BUFFs now.
1821 *) send_the_file now falls back to a read/write loop on platforms that
1822 do not have sendfile.
1823 [Ryan Bloom and Brian Havard]
1825 *) Install apachectl correctly, and substitute the proper values so
1826 that it works again. [Ryan Bloom]
1828 *) Better(??) handle platforms that lack sendfile().
1831 *) APR now has UUID generation/formatting/parsing support.
1834 *) Begin the http_filter. This is an input filter that understands
1835 the absolute basic amount required to parse an HTTP Request. The
1836 goal is to be able to split headers from request body before passing
1837 the data back to the other filters.
1840 *) Bring forward from 1.3.13 the config directory implementation
1843 *) install apxs if it is created
1846 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1847 conversions. [William Rowe]
1849 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1850 ap_add_output_filter(). [Jeff Trawick]
1852 *) Multiple build and configuration fixes
1855 -add datadir and localstatedir substitutions
1857 -fix logfilename misspelling
1858 -fix evaluation of installation dir variables and
1859 -replace $foobar by $(foobar) to be usefull in the makefile
1863 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1864 $CC_FOR_BUILD is still missing
1865 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1866 -add missing "AR=@AR@" to severaly Makefile.in's
1867 -cache result for "struct rlimit"
1868 -compile all helper programs with native and cross compiler
1869 and use the native version to generate header file
1870 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1872 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1874 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1876 *) Fix a bug where a client which only sends \n to delimit header
1877 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1878 message. Start working on ebcdic co-existance with input
1880 [William Rowe, Greg Ames]
1882 *) If mod_so is enabled in the server always create libexec, even
1883 if there are no modules installed in this directory. This is a
1884 requirement for APXS to work correctly.
1887 *) Connection oriented output filters are now stored in the
1888 conn_rec instead of the request_rec. This allows us to add the
1889 output filter in the pre-connection phase instead of the
1890 post_read_request phase, which keeps us from trying to write an
1891 error page before we have a filter to write to the network.
1892 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1894 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1895 mmap can be used across multiple buckets (default_handler with
1896 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1897 the mmap itself can't be associated with the bucket.
1900 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1903 *) Radical surgery to improve mod_isapi support under Win32.
1904 Includes a number of newer ServerSupportFunction calls, support
1905 for ReadClient (in order to retrieve POSTs greater than 48KB),
1906 and general bug fixes to more reliably load ISAPI .dll's and
1907 prevent leaking handle resources. Note: There are still
1908 discrepancies between IIS's and Apache's ServerVariables, and
1909 async calls are still not supported. Additional warnings are
1910 logged to facilitate debugging of unsupported ISAPI calls.
1913 *) Add input filtering to Apache. The basic idea for the input
1914 filters is the same as the ideas for output filters. The biggest
1915 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1916 should be called, and the order of execution for the filter itself is
1917 different. When writing an output filter, a brigade is passed in,
1918 and filters operate directly on that brigade, when done, they call
1919 ap_pass_brigade. Input filters are the exact opposite. Because input
1920 is not a push operation, filters first call ap_get_brigade. When this
1921 function returns, the input filter will be left with a valid brigade.
1922 The input filter should then operate on the brigade, and return.
1925 *) Fix building on BSD/OS using its native make. The build system
1926 falls back to the BSD .include directive on that host platform.
1929 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1930 SHA1 and plaintext password encodings. Make feature tests a
1931 bit more flexible. [William Rowe]
1933 *) Charset translation: mod_charset_lite handles output content
1934 translation in a filter. mod_charset_lite no longer ignores
1935 subrequests. A bunch of cruft related to BUFF's support for
1936 translating request and response bodies was removed.
1939 *) Move the addition of the CORE filter to the post_read_request
1940 hook in http_core.c. This removes the need to add the filter in
1941 multiple places and allows for an SSL module to be added much
1942 simpler. [Ryan Bloom]
1944 *) Fix a security problem that affects certain configurations of
1945 mod_rewrite. If the result of a RewriteRule is a filename that
1946 contains expansion specifiers, especially regexp backreferences
1947 $0..$9 and %0..%9, then it may be possible for an attacker to
1948 access any file on the web server. [Tony Finch]
1950 *) Fix a bug where errors that are detected during early request parsing
1951 don't produce visible HTTP error messages at the browser, because
1952 the core_filter wasn't present. [Greg Ames]
1954 *) Provide apr_socklen_t as a portability aid.
1955 [Victor J. Orlikowski]
1957 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1958 as well as a comment arg to the add, adduser and update cmds.
1959 update allows the user to clear or preserve pw/groups/comment.
1960 Fixed a bug in dbmmanage that prevented the check option from
1961 parsing a password followed by :group... text. Corrected the
1962 seed calcualation for Win32 systems, and added -lsdbm support.
1965 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1968 *) Avoid a segfault when parsing .htaccess files. An
1969 uninitialized tree pointer was passed to ap_build_config().
1972 *) Change the way that inet_addr & inet_network are checked for
1973 in APR's configure process to allow BeOS BONE to correctly
1974 find them. With this change BeOS BONE now builds from source
1975 with no problems. [David Reid]
1977 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1978 the end of the parameters to execve() was stored in the wrong
1979 location, overlaying the storage beyond the newargs[] array and
1980 also passing uninitialized storage to execve(), which would
1981 sometimes fail with EFAULT. [Jeff Trawick]
1983 *) Fix a bug parsing configuration file containers. With a sequence
1984 like this in the config file
1986 <IfModule mod_kilroy.c>
1989 <IfModule mod_lovejoy.c>
1994 the second container would be terminated at the blank line due to
1995 sediment in the buffer from reading the prior </IfModule> and an
1996 error message would be generated for the real </IfModule> for the
1997 second container. Also due to this problem, any two characters
1998 could be used for "</" in the close of a container.
2001 *) ap_add_filter prototype changed to remove the ctx pointer. The
2002 pointer still remains in the filter structure, but it can not be
2003 a part of the ap_add_filter prototype. The reason is that when
2004 the core uses AddFilter to add a filter to the stack it doesn't
2005 know how to allocate the ctx pointer, or even how much memory should
2006 be allocated. The filters will have to be responsible for allocating
2007 the ctx memory when they need it.
2010 *) Add an AddFilter directive. This directive takes a list of filters
2011 that should be activated for the requested resource.
2014 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
2015 some other platforms). [Jeff Trawick]
2017 *) Modify mod_include to be a filter. Currently, it has only been tested
2018 on actual files, but it should work for CGI scripts too.
2021 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
2022 writes. apr_flush() for Unix: handle interrupted writes.
2025 *) NameVirtualHost can now take "*" as an argument instead of
2026 an IP address. This allows you to create a purely name-based
2027 virtual hosting server that does not have any IP addresses in
2028 the configuration file and which ignores the local address
2029 of any connections. PR #5595, PR #4455 [Tony Finch]
2031 *) Fix some compile warnings in mod_mmap_static.c
2032 [Mike Abbott <mja@sgi.com>]
2034 *) Fix chunking problem with CGI scripts. The general problem was that
2035 the CGI modules were adding an EOS bucket and then the core added an
2036 EOS bucket. The chunking filter finalizes the chunked response when it
2037 encounters an EOS bucket. Because two EOS buckets were sent, we
2038 finalized the response twice. The fix is to make sure we only send one
2039 EOS, by utilizing a flag in the request_rec.
2042 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2043 and Win32. Previously, the first read from an apr_file_t set up via
2044 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2046 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2047 bucket, instead of using BUFF's and ap_r*.
2050 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2051 [Mike Abbott <mja@sgi.com>]
2053 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2054 code to use APR file's directly instead of going through BUFFs.
2057 *) Fix compile break on some platforms for mod_mime_magic.c
2058 [John K. Sterling <sterling@covalent.net>]
2060 *) Fix merging of AddDefaultCharset directive.
2061 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2063 *) Minor revamp of the rlimit sections of code. We now test
2064 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2065 is now "available" even if the platform doesn't support
2066 the rlimit family (it's just a noop though). [Jim Jagielski]
2068 *) Migrate the pre-selection of which MPM to use for specific
2069 platforms to hints.m4, which contains (or should contain)
2070 all platform specific "hints". [Jim Jagielski]
2072 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2075 *) Add tables with non-string/binary values to APR.
2078 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2081 *) Update PCRE to version 3.2. [Ryan Bloom]
2083 *) Change the way buckets' destroy functions are called so that
2084 they can be more directly used when changing the type of a
2085 bucket in place. [Tony Finch]
2087 *) Add generic support for reference-counting the resources used by
2088 buckets, and alter the HEAP and MMAP buckets to use it. Change
2089 the way buckets are initialised to support changing the type of
2090 buckets in place, and use it when setting aside TRANSIENT buckets.
2091 Change the implementation of TRANSIENT buckets so that it can be
2092 mostly shared with IMMORTAL buckets, which are now implemented.
2095 Changes with Apache 2.0a6
2097 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2099 *) Add a chunking filter to Apache. This brings us one step closer
2100 to removing BUFF. [Ryan Bloom]
2102 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2103 added to the stack is the last filter to be called. [Ryan Bloom]
2105 *) Apache 2.0 has been completely documented using Scandoc. The
2106 docs can be generated by running 'make docs'. [Ryan Bloom]
2108 *) Add filtered I/O to Apache. This is based on bucket brigades,
2109 Currently the buckets still use BUFF under the covers, but that
2110 should change quickly. The only currently written filter is the
2111 core filter which just calls ap_bwrite. [The Apache Group]
2113 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2114 built with thread support. [Jeff Trawick]
2116 *) Abort configuration if --with-layout was specified and there's
2117 no layout definition file. [Ken Coar]
2119 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2121 *) Add support for extension methods for the Allow response header
2122 field, and an API routine for accessing r->allowed and the
2123 list of extension methods in a unified manner. [Ken Coar]
2125 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2126 [Rob Simonson <simo@us.ibm.com>]
2128 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2129 APACHE_XLATE builds. [Jeff Trawick]
2131 *) A configuration file parsing problem was fixed. When the
2132 configuration file started with an IfModule/IfDefine container,
2133 only the last statement in the container would be retained.
2136 Changes with Apache 2.0a5
2138 *) Perchild is serving pages after passing them to different child
2139 processes. There are still a lot of bugs, but this does work. I
2140 have made requests against the same installation of Apache, and had
2141 different servers use different user IDs to serve the responses.
2142 This change moves to using socketpair instead of an AF_UNIX socket.
2145 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2146 It can't seem to pass between child processes yet, but I think we
2147 are closer now than before. This moves us back to using Unix
2148 Domain Sockets. [Ryan Bloom]
2150 *) libapr functions and types renamed with apr_ prefix.
2151 #include "apr_compat.h" for 1.3.x backwards compat
2154 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2155 return the right information on the local socket address.
2156 [Gregory Nicholls <gnicholls@level8.com>]
2158 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2159 [Gregory Nicholls <gnicholls@level8.com>]
2161 *) Add an option to not detach from the controlling terminal without
2162 going into single process mode. This allows for much easier
2163 debugging of the process startup code. [Ryan Bloom]
2165 *) ab: don't use perror() to report the failure of an APR function.
2168 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2169 scoreboard on graceful restarts.
2172 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2173 An invalid ap_proc_t was passed to ap_create_process().
2176 *) Allow modules to register filters. Those filters are still
2177 never called, but this is a step in the right direction.
2178 [Ryan Bloom and Greg Stein]
2180 *) Register the mod_cgid daemon process for cleanup so that it is
2181 killed at termination if it does not die when the parent gets
2182 SIGTERM. This change is to fix occasional problems where the
2183 process stays around. Bugs in similar logic in mod_rewrite and
2184 mod_include were also fixed. [Jeff Trawick]
2186 *) Fix a bug in the time handling. Basically, we were imploding a time
2187 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2188 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2189 uses those two fields to adjust the time value. Because of the HTTP
2190 spec, both of those values can be zero'ed out safely. This fixes
2191 the bug correctly. [Ryan Bloom]
2193 *) Fix a couple of place in the Windows code where the wrong error
2194 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2196 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2198 *) Added the APR_EOL_STR macro for platform dependent differences in
2199 logfiles and other raw text (such as all APR files). Fixes logfiles
2200 not terminated with cr/lf sequences in Win32. [William Rowe]
2202 *) Move all strings functions in APR to src/lib/apr/strings and create
2203 apr_strings.h for the prototypes. [Ryan Bloom]
2205 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2206 to repeat the syscall until we stop getting EINTR. I noticed a
2207 related problem at termination (SIGTERM) on FreeBSD when using
2208 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2209 implementation work properly with child init. Previously, ap_lock()
2210 was essentially a no-op because all children were using different
2211 locks and thus nobody ever blocked. [Jeff Trawick]
2213 *) The htdocs/ tree has been moved out of the CVS source tree into
2214 a separate area for easier development. This has NO EFFECT on
2215 end-users or Apache installations. [Ken Coar]
2217 *) Integrate the mod_dav module for WebDAV protocol handling. This
2218 adds the dav and dav_fs modules, the SDBM library, and additional
2219 XML handling utilities. [Greg Stein]
2221 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2224 *) Update the lib/expat-lite/ library (bring forward changes from
2225 the Apache 1.3 repository). [Greg Stein]
2227 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2228 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2230 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2231 machines where sendfile is detected, but nobody has written ap_sendfile.
2232 [Dave Hill <ddhill@zk3.dec.com>]
2234 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2236 *) ab would start up more connections than needed, then quit when the
2237 desired number were finished. Also fixed a logic error involving
2238 ab keepalives. [Victor J. Orlikowski]
2240 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2241 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2242 timeouts (i.e, if a timeout was specified, the pipe reverted to
2243 a full blocking pipe). Now the behaviour is more in line with
2244 Unix non-blocking pipes.
2247 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2248 cache open file handles along with accept socket reuse enables
2249 Apache 2.0 to serve non-keepalive requests for static files at
2250 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2251 and Apache 2.0 will serve almost 1200 rps on my system).
2254 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2255 supports two config directives, mmapfile (same behavious as
2256 mod_mmap_static) and cachefile. Use the cachefile directive
2257 to cache open file handles. This directive only works on systems
2258 that have implemented the ap_sendfile API. cachefile works today
2259 on Windows NT, but has not been tested on any flavors of Unix.
2262 *) Cleanup the configuration. With the last few changes the
2263 configuration process automatically:
2264 inherits information about how to build from APR. Allowing
2265 APR to inform Apache that it should or should not use -ldl
2267 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2268 based on the threading model
2270 Apache calls APR's configure process before finishing it's
2271 configuration processing, allowing for more information flow
2276 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2277 with non-zero argument makes the socket non-blocking. BeOS and
2278 OS/2 already worked this way. [Jeff Trawick]
2280 *) ap_close() now calls ap_flush() for buffered files, so write
2281 operations work a whole lot better on buffered files.
2284 *) Fix error messages issued from MPMs which explain where to change
2285 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2288 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2289 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2290 now the way that the blocking state of a pipe is manipulated.
2291 ap_block_pipe() is gone. [Jeff Trawick]
2293 *) Correct the problem where the only local host name that the IP stack
2294 can discover are 'undotted' private names. If no fully qualified
2295 domain name can be identified, the default ServerName will be set to
2296 the machine's IP address string. A warning is always provided if the
2297 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2299 *) Repair problems with config file processing which caused segfault
2300 at init when virtual hosts were defined and which caused ServerName to
2301 be ignored when there was no valid DNS setup. [Jeff Trawick]
2303 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2305 *) Add ap_sendfile implementation for AIX
2306 [Victor J. Orlikowski]
2308 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2309 apr_network_io.h, and apr_thread_proc.h.
2310 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2312 *) Bring the allocation and pool debugging code back into a working
2313 state. This will need to be tested as so far it's only been used on
2316 *) Change configuration command setup to be properly typesafe when in
2317 maintainer mode. Note that this requires a compiler that can initialise
2318 unions. [Ben Laurie]
2320 *) Turn on buffering for config file reads. Part of this was to
2321 repair buffered I/O support in Unix and implement buffered
2322 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2324 *) Win32: Fix problem where UTC offset was not being set correctly
2325 in the access log. Problem reported on news group by Jerry Baker.
2328 *) Fix segfault when reporting this type of syntax error:
2329 "</container> without matching <container> section", where
2330 container is VirtualHost or Directory or whatever.
2333 *) Prevent the source code for CGIs from being revealed when using
2334 mod_vhost_alias and the CGI directory is under the document root
2335 and a user makes a request like http://www.example.com//cgi-bin/cgi
2336 as reported in <news:960999105.344321@ernani.logica.co.uk>
2339 *) Add support for the new Beos NetwOrking Environment (BONE)
2342 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2343 final input char is incomplete; ap_bwrite_xlate() now handles
2344 incomplete final input chars. [Jeff Trawick]
2346 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2347 that a bhalfduplex call occurs before logging or else DNS and
2348 such can delay the last packet of the response. [Dean Gaudet]
2350 *) Some syscall reduction in APR on unix -- don't seek when setting
2351 up an mmap; and don't fcntl() more than once per socket.
2354 *) When mod_cgid is started as root, the cgi daemon now switches
2355 to the configured User/Group (like other httpd processes)
2356 instead of continuing as root. [Jeff Trawick]
2358 *) The prefork MPM now uses an APR lock for the accept() mutex.
2359 It has not been getting a lock at all recently. httpd -V now
2360 displays APR's selection of the lock mechanism instead of the
2361 symbols previously respected by prefork. [Jeff Trawick]
2363 *) Change the mmap() feature test to check only for existence.
2364 The previous check required features not used by Apache.
2367 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2368 sometimes mangled. The len parm to accept() was not
2369 initialized, leading sometimes to an endless loop of failed
2370 accept() calls on OS/390 and anywhere else that failed the call
2371 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2372 instead of declaring it ourselves to fix a compilation problem
2373 on Solaris. [Jeff Trawick]
2375 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2377 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2379 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2381 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2382 initialization if ALLOC_DEBUG is defined; no known symptom
2383 otherwise. [Jeff Trawick]
2385 *) Fix typo in configure script when checking for mod_so. bash
2386 doesn't seem to have a problem but /bin/sh on Solaris does.
2387 Symptom: "./configure: test: unknown operator =="
2390 *) Rebind the Win32 NT and 9x services control into the MPM.
2391 All console, WinNT SCM and Win9x pseudo-service control code is
2392 now wrapped within the WinNT MPM.
2395 *) Make a copy of getenv("PATH") before storing for later use. Some
2396 getenv() implementations use the same storage for successive calls.
2397 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2399 *) Server Tokens work in 2.0 again. This also propogates the change
2400 to allow just the product name in the server string using
2404 Changes with Apache 2.0a4
2406 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2407 won't need to call it. [Greg Ames, Jeff Trawick]
2409 *) Move pre_config hook call to between configuration read and config
2410 tree walk. This allows all modules to implement pre_config hooks
2411 and know that they will be called at an appropriate time.
2414 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2417 *) Add pre-config hooks back to all modules.
2420 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2421 ContentDigest enabled and we can't/don't mmap the file.
2424 *) We now report the correct line number for syntax errors in config
2425 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2427 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2428 related bugs, and changed shmem/locking to use apr API. Shared-mem
2429 is currently disabled, however, because of problems with graceful
2430 restarts. [Ronald Tschalär]
2432 *) Fix corruption of IFS variable in --with-module= handling.
2433 Depending on the user's shell or customization thereof, there
2434 would be errors generating ap_config_auto.h later in the configure
2435 procedure. [Jeff Trawick]
2437 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2438 isn't used (as in 1.3), except that on Unix it is now logged via
2439 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2440 to the error log. [Greg Ames, Jeff Trawick]
2442 *) Add '-D' argument processing for run time configuration defines.
2445 *) Organize http_main.c as independent code, such that no code or
2446 global data is exported from it. WIN32 will dynamically link it
2447 to the server core, so this will prevent mutual dependency.
2450 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2451 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2454 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2455 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2457 *) Add mod_charset_lite for configuring character set translation.
2460 *) Add '-n' option to htpasswd to make it print its user:pw record
2461 on stdout rather than having to frob a text file. [Ken Coar]
2463 *) Fix saferead. Basically, we flush the output buffer if a read on the
2467 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2468 a conversion is single-byte only. [Jeff Trawick]
2470 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2471 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2474 *) Fix some minor errors where pid was being manipulated as an int
2475 instead of the portable pid_t. [Roy Fielding]
2477 *) Fix some error log prints that were printing the pointer to a
2478 structure rather than the pid within the structure.
2479 [Jeff Trawick, Roy Fielding]
2481 *) ab: Fix a command-line processing bug; track bad headers in
2482 err_response; support reading headers up to 2K.
2483 [Ask Bjoern Hansen <ask@valueclick.com>]
2485 *) Fix ap_resolve_env() so that it handles new function added in a prior
2486 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2487 config file.") as well as the constructs used by mod_rewrite.
2488 [Paul Reder <rederpj@raleigh.ibm.com>]
2490 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2492 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2493 APR to perform translation, instead of accessing the hard-coded tables
2494 in 1.3's ebcdic.c. [Jeff Trawick]
2496 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2499 *) Add the ability to hook into the config file reading phase. Basically
2500 if a directive is specified EXEC_ON_READ, then when that directive is
2501 read from the config file, the assocaited function is executed. This
2502 should only be used for those directives that must muck with HOW the
2503 server INTERPRETS the config. This should not be used for directives
2504 that re-order or replace items in the config tree. Those changes should
2505 be made in the pre-config step.
2508 *) Add mod_example to the build system.
2511 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2512 byte character sets. [Jeff Trawick]
2514 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2515 Kraemer and Oliver Reh originally according to the change log).
2518 *) Fix a couple of problems in RFC1413 support (controlled by the
2519 IdentityCheck directive). Apache did not build the request string
2520 properly and more importantly Apache would loop forever if the
2521 would-be ident server dropped the connection before sending a
2522 properly terminated response. [Jeff Trawick]
2524 *) apxs works in 2.0.
2527 *) Reliable piped logs work in 2.0.
2530 *) Introduce a hash table implementation into APR to be used for
2531 replacing tables and other random data structures in Apache.
2534 *) Add some more error reporting to htpasswd in the case of problems
2535 generating or accessing the temporary file. Also, pass in a
2536 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2537 is defined). [Ken Coar]
2539 *) Configure creates config.nice now containing your configure
2540 options. Syntax: ./config.nice [--more-options]
2543 *) Fix various return code problems in APR on Win32. For most of
2544 these, APR was returning APR_EEXIST instead of GetLastError()/
2545 WSAGetLastError(). [Jeff Trawick]
2547 *) Make piped logs work again in version 2.0
2550 *) Add VPATH support to UNIX build system of Apache and APR.
2553 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2557 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2558 Patch submitted to author.
2561 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2562 /sbin in PATH on FreeBSD (all submitted to rse previously)
2565 *) Fix building Pthread-based MPMs on OpenBSD
2566 [Sascha Schumann] PR#26
2568 *) Fix ap_readdir() problem on systems where d_name[] field in
2569 struct dirent is declared with only one byte. (This problem only
2570 affected multithreaded builds.) This caused a segfault during
2571 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2572 least). [Jeff Trawick]
2574 *) Fix some make-portability problems on at least Tru64, Irix
2576 [Sascha Schumann] PR#18, PR#39
2578 *) Add ap_sigwait() to support old-style sigwait() on systems
2579 like OS/390 and UnixWare.
2582 *) Add POSIX-thread flags for more platforms.
2585 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2586 (on Unix, at least) to handle resolver errors. Fix a bug in
2587 the definition of APR_ENOMEM so that ap_strerror() can spit
2588 out the correct error message for it.
2591 Changes with Apache 2.0a3
2593 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2596 *) API: *HOOK* macros now have an AP_ prefix
2599 *) Win32: Eliminate redundant calls to initialize winsock.
2600 [Tim Costello <timcostello@ozemail.com.au>]
2602 *) Fix bugs initializing ungetchar for pipes.
2603 [Chia-liang Kao <clkao@CirX.ORG>]
2605 *) The ab program in the src/support directory is now portable using
2609 *) Support directory is being compiled when the server is built
2612 *) The configure option --with-program-name has been added to allow
2613 developers to rename the executable at configure time. This also
2614 changes the name of the config files to match the executable's name.
2617 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2618 containing version numbers. [Martin Pool]
2620 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2621 Unix; access_log and error_log now created with these perms; non-
2622 Unix is unaffected [Jeff Trawick]
2624 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2625 Replaced more magic numbers with MD5_DIGESTSIZE.
2626 [William Rowe, Roy Fielding]
2628 *) Win32: Get mod_auth_digest compiling and added to the Windows
2629 build environment. Not tested and I'd be suprised if it
2630 actually works. [Bill Stoddard]
2632 *) Revamp the Win32 make environment. Makefiles have been removed and
2633 Apache.dsw created to bring together all the pieces. Create new file
2634 os/win32/BaseAddr.ref to define module base addresses (to prevent
2635 dll relocation at start-up).
2636 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2638 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2639 of the \015, \012, and \015\012 constants with macros.
2640 [Greg Ames <gregames@us.ibm.com>]
2642 *) Add ap_xlate_open() et al for translation of text between different
2643 character sets. The initial implementation requires iconv().
2646 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2647 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2649 *) CGI output is being timed out now.
2652 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2653 is used by the new apr file. There is no reason to create a new file
2654 with the same lifetime as the original file.
2657 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2658 module base addresses. This will help shooting seg faults
2659 in the field. [William Rowe <wrowe@lnd.com>]
2661 *) Update Apache on Windows documentation. Add new document
2662 describing how to compile Apache on Windows.
2663 [William Rowe <wrowe@lnd.com>]
2665 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2666 microseconds instead of seconds. Some storage leaks and other
2667 minor bugs in related code were fixed. [Jeff Trawick]
2669 *) Win32: First cut at getting mod_isapi working under 2.0
2670 [William Rowe <wrowe@lnd.com>]
2672 *) First stab at getting mod_auth_digest working under 2.0
2673 quick change summary:
2674 - moved the random byte generation (ap_generate_random_bytes) into APR
2675 - now uses ap_time_t
2676 - compiles and runs on linux
2678 [Brian Martin <bmartin@penguincomputing.com>]
2680 *) Win32: Move the space stripping of physical service names
2681 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2682 unresolved symbol. Add dependency checking to the
2683 CreateService call to ensure TCPIP and AFP (winsock) is started
2685 [William Rowe <wrowe@lnd.com>]
2687 *) Win32: Add code to perform latebinding on functions that may
2688 not exist on all levels of Windows where Apache runs. This
2689 is needed to allow Apache to start-up on Win95/98. All calls
2690 to non portable functions should be protected with
2691 ap_oslevel checks to prevent runtime segfaults.
2692 [William Rowe <wrowe@lnd.com>]
2694 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2696 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2698 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2699 This addresses PR 1623. Still need to address timing out runaway
2700 CGI scripts. [Bill Stoddard]
2702 *) Win32: Make ap_stat Windows 95/98 friendly
2703 [William Rowe <wrowe@lnd.com>]
2705 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2706 always fail. Need to initialise the dwOSVersionInfoSize member of the
2707 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2710 The patch also enhances ap_get_oslevel (and the associated enum) to
2711 handle selected service packs for NT4, and adds recognition for
2712 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2713 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2714 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2716 *) Get mod_rewrite building and running, and mod_status building for Win NT
2717 [Allan Edwards <ake@raleigh.ibm.com>]
2719 *) Patch to port mod_auth_db to the 2.0 api and also to support
2720 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2721 2.7.7. It should work with version 1 as well but I haven't tested it.
2722 [Brian Martin <bmartin@penguincomputing.com>]
2724 *) Get APR DSO code working under Windows. Includes cross platform
2726 [Tim.Costello@BTFinancialgroup.com]
2728 *) Fix some of the Windows APR time functions.
2731 *) FAQ changes related to tidying up historical documents on the web site.
2732 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2734 *) Move Windows DSO code into APR.
2737 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2738 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2739 at build time. At this point, the server will not compile on Windows because
2740 of the recent DSO commits. Fixing those next.
2741 [Bill Rowe & Bill Stoddard]
2743 *) Added error checking for file I/O APR routines.
2744 [Jon Travis <jtravis@covalent.net>]
2746 *) APR: Don't use the values of resolver error codes for the
2747 corresponding APR error codes. On Unix and Win32, return the
2748 proper APR error code after a resolver error. [Jeff Trawick]
2750 Changes with Apache 2.0a2
2752 *) Renamed the executable back to httpd on all platforms other
2756 *) Allow BeOS to survive restarts, log properly and a few
2757 small things it had problems with due to the way it setup
2758 users and groups. [David Reid]
2760 *) Get mod_rewrite working with APR locks
2761 [Paul Reder <rederpj@raleigh.ibm.com>]
2763 *) Actually remove the sempahore when the lock cleanup routine
2764 is called on BeOS. [David Reid]
2766 *) Clear hook registrations between reads of the config file.
2767 When DSOs are unloaded and re-loaded the old hook pointers may
2768 no longer be valid. This fix eliminates potential segfaults.
2769 [Allan Edwards <ake@raleigh.ibm.com>]
2771 *) Fix a problem with Sigfunc not being defined or bypassed
2772 if sigaction() wasn't found. [Jim Jagielski]
2774 *) Fix the locking mechanism on BSD variants. They now use fcntl
2775 locks. This allows the server to start and serve pages.
2778 *) First cut at getting the Win32 installer to work
2779 [William Rowe <wrowe@lnd.com>]
2781 *) Get htpasswd compiling under Windows
2782 [William Rowe <wrowe@lnd.com>]
2784 *) Change the log message for a bind() failure to show the
2785 interface and port number. [Jeff Trawick]
2787 *) Import the documentation from 1.3.12 and bring parts of it
2788 up-to-date with respect to the changes that have occurred
2792 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2793 now logged correctly on BeOS.
2796 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2797 Makefile.win includes the same user interface as the old
2799 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2801 *) Win32 exec now uses COMSPEC environment string for command
2802 shell path resolution.
2803 [William Rowe <wrowe@lnd.com>] PR#3715
2805 *) Win32: ap_connect() was not returning correct error condition
2807 [Allen Prescott <allen@clanprescott.com>]
2809 *) Win32: ap_open() was broken on Win9x because an NT-specific
2810 flag was passed to CreateFile. ap_puts() added an unnecessary
2812 [Jeff Trawick <trawick@us.ibm.com>]
2814 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2815 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2816 confusing ee/et name and made all extensions language/dialect
2817 rather than country reflecting. Changed example files to
2818 explicit reflect the ISO charset and added a few common
2819 ones to the example config [dirkx]
2821 *) Extend external module capability. To use this, you call
2822 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2825 *) Backported the various "default charset" fixes from 1.3.12,
2826 including the AddDefaultCharset directive. [Jim Jagielski]
2828 *) Added the capability to do ${ENVVAR} constructs in the
2829 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2830 it does this on a line by line basis; i.e. if the envvar
2831 expands to something with spaces you have to protect it
2832 by adding quotes around it (Unless of course you expect it
2833 to contains more than one argument. Alternatively you
2834 can compile it on a per token basis; which is what people
2835 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2836 hampers fancier hacks.
2837 [Dirk-Willem van Gulik]
2839 *) Changed the 'ErrorDocument' syntax in that it NO longer
2840 supports the asymetric
2842 ErrorDocument 301 "Some message
2844 Note the opening " quote, without a closing quote. It now
2845 has either the following syntaxes
2847 ErrorDocument XXX /local/uri
2848 ErrorDocument XXX http://valid/url
2849 ErrorDocument XXX "Some Message"
2851 The recognition heuristic is: if it has a space it
2852 is a message. If it has no spaces and starts with a /
2853 or is a valid URL then treat it that way. Otherwise it
2854 is assumed to be a message.
2856 This breaks backward compatibility but makes live a hell
2857 of a lot easier for GUI's and config file parsers.
2858 [Dirk-Willem van Gulik]
2860 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2861 syntax into a 'on' or 'off' syntax. As it currently is the
2862 only non nesting token which uses NO_ARGS and thus is an
2863 absolute pain for any config interface automation. This
2864 breaks backward compatibility. [Dirk-Willem van Gulik]
2866 *) Add ability to add external modules to the build process. This is
2867 done with --with-module=/path/to/module. Modules can only be added
2868 as static modules at this point.
2871 Changes with Apache 2.0a1
2873 *) Fix FreeBSD 3.3 core dump.
2874 Basically, ap_initialize() needs to get called before
2875 create_process(), since create_process() passes op_on structure
2876 to semop() to get a lock, but op_on isn't initialized until
2877 ap_initialize() calls setup_lock(). Here is a slight
2878 rearrangement to main() which calls ap_initialize() earlier...
2879 [Jeff Trawick <trawick@us.ibm.com>]
2881 *) Enable Apache to use sendfile/TransmitFile API
2882 [Bill Stoddard, David Reid, Paul Reder]
2884 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2888 *) Make file I/O and network I/O writev/sendv APIs consistent.
2889 Eliminate use of ap_iovec_t and use Posix struct iovec.
2890 Use seperate variable on ap_writev to set the number of iovecs
2891 passed in and number of bytes written.
2894 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2895 with ap_create_file_iol(). ap_create_file_iol() requires that
2896 the file be opened prior to the call using ap_open().
2899 *) Port mod_include and mod_cgi to 2.0
2900 [Paul Reder, Bill Stoddard]
2902 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2903 bytes_read/bytes_written is always valid (never -1). Plus
2904 some fixes to buff.c to correct problems introduced by the
2905 errno => ap_status_t changes a while back. Plus a fix to
2906 chunked encoding introduced right at the beginning of 2.0.
2909 *) Revamped UNIX build system to use autoconf and libtool.
2910 [Manoj Kasichainula, Sascha Schumann]
2912 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2914 *) More rigorous checking of Host: headers to fix security problems
2915 with mass name-based virtual hosting (whether using mod_rewrite
2916 or mod_vhost_alias).
2917 [Ben Hyde, Tony Finch]
2919 *) Add back support for UseCanonicalName in <Directory> containers.
2920 [Manoj Kasichainula]
2922 *) Added APLOG_STARTUP log type. This allows us to write an error
2923 message without any of the date and time information. As a part
2924 of this change, I also removed all of the calls to fprintf(stderr
2925 and replaced them with calls to ap_log_error using APLOG_STARTUP
2926 writing to stderr is no longer portable, because we don't direct
2927 stderr to the error log on all platforms.
2930 *) Convert error logging functions to take errno as an argument.
2931 This makes our error logs more portable, because some Windows API's
2932 don't set errno. This change allows us to still output a valid
2933 message on all of our platforms.
2936 *) mod_mime_magic runs in 2.0-dev now.
2937 [Paul Reder <rederpj@raleigh.ibm.com>]
2939 *) sendfile has been added to APR.
2940 [John Zedlewski <zedlwski@Princeton.EDU>]
2942 *) buff.c has been converted to no longer use errno.
2943 [Manoj Kasichainula]
2945 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2946 interface adaption to APR functions did it. [Martin Kraemer]
2948 *) Support DSOs properly on 32-bit HP-UX 11.0
2949 [Dilip Khandekar <dilip@cup.hp.com>]
2951 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2952 [Ralf S. Engelschall]
2954 *) Cleaned APR build environment integration and bootstrap APR
2955 automatically for developers from src/Configure.
2956 [Ralf S. Engelschall]
2958 *) Fixed building of src/support/htpasswd.c
2959 [Ralf S. Engelschall]
2961 *) When generating the Location: header, mod_speling forgot
2962 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2965 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2967 *) Change all pools to APR contexts. This is the first step to
2968 incorporating APR into Apache. [Ryan Bloom]
2970 *) Move "handler not found" warning message to below the check
2971 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2972 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2974 *) Support line-continuation feature in config.option file and
2975 allow the loading of multiple option sections at once via
2976 ``--with-option=<section1>,<section2>,...''
2977 [Ralf S. Engelschall]
2979 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2981 Changes with Apache MPM
2983 *) Use asynchronous AcceptEx() and a completion port to accept and
2984 dispatch connections to threads in Windows NT/2000.
2987 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2990 *) Implement the APACI --with-option facility
2991 (per default used the config.option file).
2992 [Ralf S. Engelschall]
2994 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2996 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2997 Replace pre_connection module call with a register_hook call and
2998 implement pre_connection as a hook. The intent is that these hooks will
2999 be extended to allow Apache to be multi-protocol, and also to allow the
3000 calling order to be specified on a per-hook/per-module basis.
3003 *) Implement mpm_* methods as "modules". Each method gets its own
3004 subdir in src/modules (eg: src/modules/prefork). Selection
3005 of method uses Rule MPM_METHOD. [Jim Jagielski]
3007 *) Port the hybrid server from the apache-apr repository as
3008 mpm_mpmt_pthread. [Manoj Kasichainula]
3010 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
3011 amongst the unix MPMs.
3013 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
3014 signal handling for the new world order. [Dean Gaudet]
3016 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
3017 of alloc.c for now. [Dean Gaudet]
3019 *) Handle partial large writes correctly. [Ben Laurie]
3021 *) Eliminate conn_rec's pointer to server. All it knows is the base server
3022 based on IP/port. [Ben Laurie]
3024 *) Port a bunch of modules to the new module structure.
3025 ["Michael H. Voase" <mvoase@midcoast.com.au>]
3027 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
3029 *) Basic restructuring to introduce the MPM concept; includes various
3030 changes to the module API... better described by
3031 docs/initial_blurb.txt. [Dean Gaudet]
3033 Changes with Apache pthreads
3035 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3036 buff operations (generally over a network).
3037 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3039 *) Created http_accept abstraction. Added 4 new functions (not exported):
3040 init_accept(), begin_accepting_requests(), get_request(),
3041 stop_accepting_requests() [Bill Stoddard]
3043 *) Fix to ap_rprintf call that allows mod_info to work properly.
3044 [James Morris <jmorris@intercode.com.au>]
3046 *) user and ap_auth_type fields were moved from connection_rec to
3047 request_rec. [Ryan Bloom]
3049 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3050 needed in a threaded server.
3052 *) Initial pthread implementation from from Dean's apache-nspr code.
3053 [Bill Stoddard, Ryan Bloom]
3056 Changes with Apache 1.3.9
3058 *) Remove bogus error message when a redirect doesn't set Location.
3059 Instead, use an empty string to avoid coredump if the error message
3060 was supposed to include a location. [Roy Fielding]
3062 *) Don't allow configure to include mod_auth_digest unless it is
3063 explicitly requested, even if the user asked for all modules.
3066 *) Translate module names to dll names for OS/2 so that they are no more
3067 than 8 characters long and have an extension of "dll" instead of "so".
3070 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3071 Fix test-compile check to check for randbyte instead of trand32.
3072 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3073 and tweak to make Amaya happier. [Ronald Tschalär]
3075 *) Ensure that the installed expat include files are world readable,
3076 just like the other header files. [Martin Kraemer]
3078 *) Fixed generated AddModule adjustments in APACI's `configure' script
3079 in order to allow (new) modules like mod_vhost_alias to be handled
3080 correctly (which was touched by the adjustments for mod_alias).
3081 [Ralf S. Engelschall]
3083 *) For binary builds, add -R flag to apachectl to work around the lack of
3084 an absolute path to the ./libexec directory where the libhttp.ep file
3085 is needed for SHARED_CORE architectures. [Randy Terbush]
3087 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3088 problem observed by some Win95/98 users where they get CGI script
3089 output sent to the console. [Bill Stoddard]
3091 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3092 routines are now called ap_base64* and are 'plain' (i.e., no
3093 pool access or anything clever). Inside util.c the routines acting
3094 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3095 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3096 now but deprecated. [dirkx]
3098 *) Clean up the base64 and SHA1 additions and make sure they are
3099 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3100 files. [Roy Fielding]
3102 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3103 checking. Allow compiling on VS 6.0. [Randy Terbush]
3105 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3107 *) Use TestCompile to search for the truerand library (rather than blindly
3108 assuming its existence). If it is not found, complain (but do not
3109 exit - yet). [Martin Kraemer]
3111 *) We forgot to add the new exported function names to
3112 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3114 *) Add description of -T command-line option to usage().
3115 [Ralf S. Engelschall]
3117 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3118 searched only AFTER libap has been searched, because libap needs
3119 some symbols from libos. [Martin Kraemer]
3121 *) Fix conflict with original mod_digest related to the symbol of the
3122 module dispatch list (which has to be unique for DSO and follow the
3123 usual conventions for the installation procedure).
3124 [Ralf S. Engelschall]
3126 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3127 for other platforms as well. [Martin Kraemer]
3129 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3130 types by AP_LONG and replace reference to renamed variable 'ubuf'
3131 by 'buffer'. [Martin Kraemer]
3133 Changes with Apache 1.3.8 [not released]
3135 *) Flush the output buffer immediately after sending an error or redirect
3136 response, since the result may be needed by the client to abort a
3137 long data transfer or restart a series of pipelined requests.
3138 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3140 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3141 [Ian Turner <iant@sequent.com>] PR#4735
3143 *) Local struct mmap in http_core.c conflicted with system structure
3144 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3146 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3147 [Ronald Tschalär <ronald@innovation.ch>]
3149 *) Fix a memory leak where the module counts were getting messed
3150 up across restarts. [David Harris <dharris@drh.net>]
3152 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3153 properly in mod_access.
3154 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3156 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3157 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3159 *) PORT: Support for compaq/tandem/com.
3160 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3162 *) Added SHA1 password encryption support to easy migration from
3163 Netscape servers. See support/SHA1 for more information.
3164 Caused the separation of ap_md5.c into md5, sha1 and a general
3165 ap_checkpass.c with just a validate_passwd routine. Added a
3166 couple of flags to support/htpasswd. Some reuse of the to64()
3167 function; hence renamed to ap_to64().
3168 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3170 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3171 with ASCII/EBCDIC conversions in "ident" query.
3172 [David McCreedy <McCreedy@us.ibm.com>]
3174 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3175 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3176 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3178 *) Fix SIGSEGV on some systems because the Vary fix below included
3179 a call to table_do with a variable argument list that was not
3180 NULL terminated. Replaced with better implementation. [Roy Fielding]
3182 Changes with Apache 1.3.7 [not released]
3184 *) The "Vary" response header field is now sanitised right before
3185 the header is sent back to the client. Multiple "Vary" fields
3186 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3187 "Vary: host, negotiate, host, accept-language") are reduced to
3188 single instances. This is a better solution than the force-no-vary
3189 one (which is still valid for clients that can't cope with Vary
3190 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3192 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3194 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3195 least on Linux and FreeBSD for now.
3198 *) Win32: More apache -k restart work. Restarts are now honored
3199 immediately and connections in the listen queue are -not- lost.
3200 This is made possible by the use of the WSADuplicateSocket()
3201 call. The listeners are opened in the parent, duplicated, then
3202 the duplicates are passed to the child. The original listen sockets
3203 are not closed by the parent across a restart, thus the listen queue
3205 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3207 *) Fix handling of case when a client has sent "Expect: 100-continue"
3208 and we are going to respond with an error, but get stuck waiting to
3209 discard the body in the pointless hope of preserving the connection.
3210 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3212 *) Fix 'configure' to work correctly with SysV-based versions of
3213 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3215 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3216 built-in values. Add "-e" option which works like -i but doesn't
3217 install the DSO; useful for editing httpd.conf with apxs. Fix
3218 editing code so that multiple invocations of apxs -a will not
3219 create duplicate LoadModule/AddModule entries; apxs can now be
3220 used to re- enable/disable a module. [Wilfredo Sanchez]
3222 *) Win32: Update the server to use Winsock 2. Specifically, link with
3223 ws2_32.lib rather than wsock32.lib. This gives us access to
3224 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3225 Win 95 users may need to update their TCP/IP stack to pick up
3226 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3227 [Bill Stoddard stoddard@raleigh.ibm.com]
3229 *) Win32: Redirect CGI script stderr (script debug info) into the
3230 error.log when CGI scripts fail. This makes Apache on Win32
3231 behave more like Unix.
3232 [Bill Stoddard stoddard@raleigh.ibm.com]
3234 *) Fixed `httpd' usage display: -D was missing.
3235 [Ralf S. Engelschall] PR#4614
3237 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3238 [Ralf S. Engelschall] PR#4561, PR#4562
3240 *) OS/2: Fix problem with accept lock semaphores where server would die with
3241 "OS2SEM: Error 105 getting accept lock. Exiting!"
3242 [Brian Havard] PR#4505
3244 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3245 [Randy Terbush <randy@covalent.net>]
3247 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3248 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3250 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3251 command potentially _is_ GCC. [Ralf S. Engelschall]
3253 *) Fix apxs build issues on AIX
3254 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3256 *) DocumentRoot Checking: Under previous versions, when Apache
3257 first started up, it used to do a stat of each DocumentRoot to
3258 see if it existed and was a directory. If not, then an error
3259 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3260 does not exist, you will get error messages in error_log. If
3261 the '-t' command line option is used (to check the configuration)
3262 the check of DocumentRoot IS performed. An additional command
3263 line option, '-T', has been added if you want to avoid the
3264 DocumentRoot check even when checking the configuration.
3267 *) Win32: The query switch "apache -S" didn't exit after showing the
3268 vhost settings. That was inconsistent with the other query functions.
3269 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3271 *) Win32: Changed behaviour of apache -k restart.
3272 Previously, the server would drain all connections in the stack's
3273 listen queue before honoring the restart. On a busy server, this
3274 could take hours. Now, a restart is honored almost immediately.
3275 All connections in Apache's queues are handled but connections in
3276 the stack's listen queue are discarded. Restart triggered by
3277 MaxRequestPerChild is unchanged.
3278 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3280 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3281 the accept loop. Good for a 5% performance boost. Cleaned up
3282 parent/child process management code.
3283 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3285 *) Added ceiling on file size for memory mapped files.
3286 [John Giannandrea <jg@meer.net>] PR#4122
3288 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3289 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3290 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3292 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3293 use this at least for Expat. [Ralf S. Engelschall]
3295 *) Allow .module files to specify libraries with Lib:.
3298 *) Allow SetEnvIf[NoCase] to test environment variables as well
3299 as header fields and request attributes. [Ken Coar]
3301 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3302 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3304 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3305 never accepted into any standard, and it opens up certain DoS
3306 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3308 *) TestCompile updated. We can now run programs and output the
3309 results during the Configure process. [ Jim Jagielski]
3311 *) The source is now quad (long long) aware as needed. Specifically,
3312 the Configure process determines the correct size of off_t and
3313 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3314 provides for the 'q' format qualifier (if quads are not available,
3315 'q' is silently "demoted" to long). [Jim Jagielski]
3317 *) When the username or password fed to htpasswd is too long, include the
3318 size limit in the error message. Also report illegal characters
3319 (currently only ':') in the username. Add the size restrictions
3320 to the man page. [Ken Coar]
3322 *) Fixed the configure --without-support option so it doesn't result in
3323 an infinite loop. [Marc Slemko]
3325 *) Piped error logs could cause a segfault if an error occured
3326 during configuration after a restart.
3327 [Aidan Cully <aidan@panix.com>] PR#4456
3329 *) If a "Location" field was stored in r->err_headers_out rather
3330 than r->headers_out, redirect processing wouldn't find it and
3331 the server would core dump on ap_escape_html(NULL). Check both
3332 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3333 if Location isn't set. [Doug MacEachern, Ken Coar]
3335 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3336 of the Expat 1.0.2 distribution. [Greg Stein]
3338 *) Replace regexec() calls with calls to a new API stub function
3339 ap_regexec(). This solves problems with DSO modules which use the regex
3340 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3342 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3343 environment variables can be set according to the protocol version
3344 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3346 *) Add DSO support for OpenStep (Mach 4.2) platform.
3347 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3349 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3350 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3352 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3353 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3355 *) Better DSO flags recognition on NetBSD platforms using ELF.
3356 [Todd Vierling <tv@pobox.com>] PR#4310
3358 *) Always log months in english format for %t in mod_log_config.
3359 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3361 *) Support for server-parsed and multiview-determined ReadmeName and
3362 HeaderName files in mod_autoindex. Removed the restriction on
3363 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3364 routines will deal with the access issues. (It's now possible to
3365 have {site|group|project|customer|...} wide readmes and headers.)
3366 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3369 *) When stat() fails, don't assume anything about the contents of
3370 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3372 *) It's OK for a semop to return EINTR, just loop around and try
3373 again. [Dean Gaudet]
3375 *) Fix configuration engine re-entrant hangups, which solve a
3376 handful of problems seen with mod_perl <Perl> configuration sections
3377 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3379 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3380 by default when building with APACI; allow for platform-specific
3381 variable defaults in configure. [Wilfredo Sanchez]
3383 *) Do setgid() before initgroups() in http_main; some platforms
3384 zap the grouplist when setgid() is called. This was fixed in
3385 suexec earlier, but the main httpd code missed the change.
3386 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3388 *) Add recognition of .tgz as a gzipped tarchive.
3389 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3391 *) mod_include's fsize/flastmod should allow only relative paths, just
3392 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3394 *) OS/2: Add support for building loadable modules using DLLs.
3397 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3400 *) Fix minor but annoying bug with the test for Configuration.tmpl
3401 being newer than Configuration so that it is less likely to fail
3402 when using APACI and shadow sources. [Wilfredo Sanchez]
3404 *) PORT: Add initial support for Mac OS (versions 10.0 and
3405 greater). Use Mac OS X Server layout for now. Clean up dyld code
3406 in unix/os.c, and don't install the dyld error handlers, which
3407 are no longer needed in Mac OS. [Wilfredo Sanchez]
3409 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3410 locations to appropriate ones for user-built (as opposed to
3411 system) installs. [Wilfredo Sanchez]
3413 *) Modify mod_autoindex's handling of AddDescription so that the
3414 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3416 *) Add functionality to the install-bindist.sh script created by
3417 binbuild.sh to use tar when copying distribution files to the
3418 serverroot. This allows upgrading an existing installation
3419 without nesting the new distribution in the old.
3421 install-bindist.sh now detects the local perl5 path to install
3422 apxs and dbmmanage with proper path to perl interpreter.
3424 Add an install-binsupport target which copies the source files
3425 for apxs and dbmmanage to bindist to allow these scripts to
3426 be properly installed relative to the destination serverroot.
3427 [Randy Terbush, Covalent Technologies, randy@covalent.net]

3543 htpasswd utility was limiting passwords to only 8 characters.
3546 *) EBCDIC platforms: David submitted patches for two bugs in the
3547 MD5 digest port for EBCDIC machines:
3548 a) the htdigest utility overwrote the old contents of the digest file
3549 b) the Content-MD5 header value (ContentDigest directive) was wrong
3550 when the returned file was not converted from EBCDIC, but was a
3551 binary (e.g., image file) in the first place.

3593 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3594 a roughly 5 fold speed up. [Brian Havard]
3596 *) proxy ftp: instead of using the hardwired string "text/plain" as
3597 a fallback type for files served by the ftp proxy, use the
3598 ap_default_type() function to determine the configured type.
3599 This allows for special configurations like
3600 <Directory proxy:ftp://some.host>
3601 DefaultType gargle/blurb
3603 Additionally, add the Content-Encoding: header to FTP proxy replies
3604 when the encoding is defined (by the AddEncoding directive).
3605 Because it was missing, it was almost impossible to browse compressed
3606 files using the FTP proxy (works now perfectly in Communicator).
3607 The ftp proxy now also returns the Date: and Server: header lines (if not
3608 much else... This code is "somewhat" broken) like normal requests do.
3611 *) Be more smart in APACI's configure script when determining the UID/GID

3728 *) In configure, do not append the target name to the directory path if
3729 the path already contains "apache". [Ralf S. Engelschall]
3731 *) SIGPIPE is now ignored by the server core. The request write routines
3732 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3733 correctly check for output errors and mark the connection as aborted.
3734 Replaced many direct (unchecked) calls to ap_b* routines with the
3735 analogous ap_r* calls. [Roy Fielding]
3737 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3738 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3739 Furthermore map lookups for non-existent keys are now cached as well.
3740 Additionally "txt" maps are now parsed with simple string functions
3741 instead of using ap_pregcomp(). As a side effect a bug that prevented
3742 the usage of keys containing the "," character was fixed.
3743 The changes drastically improve the performance when large rewrite maps
3745 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160

3758 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3760 *) Add support for \n and \t to mod_log_config, can be used to produce
3761 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]

3793 *) Allow apache acting as a proxy server to relay the real
3794 reason of a failure to a client rather than the "internal
3795 server error" it does currently. The general exposure mechanism
3796 can be triggered by any module by setting the "verbose-error-to"
3797 note to "*"; this allows more than just proxy errors to be exposed.

3806 *) Tweak modules Makefile generated by Configure so that it handles
3807 the test case of no modules being selected. [chaz@reliant.com]
3809 *) Added a <LimitExcept method ...> sectioning directive that allows
3810 the user to assign authentication control to any HTTP method that
3811 is *not* given in the argument list; i.e., the logical negation
3812 of the <Limit> directive. This is particularly useful for controlling
3813 access on methods unknown to the Apache core, but perhaps known by
3814 some module or CGI script. [Roy Fielding, Tony Finch]
3816 *) Prevent apachectl from complaining if the PIDFILE exists but
3817 does not contain a process id, as might occur if the server is
3818 being rapidly restarted. [Wilfredo Sanchez]
3820 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3822 *) Entity tag comparisons for If-Match and If-None-Match were not being

3830 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3831 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3833 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3834 to util.c for parsing an HTTP header field value to extract the next
3835 list item, taking into account the possible presence of nested comments,
3836 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3837 insignificant whitespace and lowercases non-quoted tokens.
3838 [Roy Fielding] PR#2065
3840 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3841 code different from 500. This allows the proxy to, e.g., return
3842 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3844 *) Fix ordering of language variants for the case where the traditional
3845 negotiation algorithm is being used with multiple language variants
3846 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3848 *) Do not round the TCN quality calculation to 5 decimal places,
3849 unlike RFC 2296, because the calculation might need 12 decimal places
3850 to get the right result. [Roy Fielding]
3852 *) Remove unused code to disable transparent negotiation when
3853 negotiating on encoding only, as we now handle encoding too
3854 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3855 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3856 some debugging statements within mod_negotiation. [Koen Holtman]
3858 *) Fixed a rare memory corruption possibility in mod_dir if the index
3859 file is negotiable and no acceptable variant can be found.
3860 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3862 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3863 searching the Win32 registry for script interpreters.
3866 *) Win32: The compiled-in default filename for the error log is now
3867 error.log, which matches the default in the distributed httpd.conf.
3870 *) Win32: Any error messages from -i or -u command line options are now
3871 displayed on the console output rather than sent to the error log.
3872 Also the "Running Apache..." message is not output unless Apache is
3873 going to serve requests. [Paul Sutton]
3875 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3876 and use a private significator ('$apr1$') to mark passwords as
3877 being smashed with our own algorithm. Also abstract the password
3878 checking into a new ap_validate_password() routine. [Ken Coar]
3880 *) Win32: The filename validity checker now allows "COM" but refuses
3881 access to "COM1" through "COM4". This allows filenames such
3882 as "com.name" to be served. [Paul Sutton] PR#3769.
3884 *) BS2000: Adapt to the new ufork() system call interface which will
3885 make subtasking easier on the OSD/POSIX mainframe environment.

3911 [Jim Jagielski] PR#3671
3913 *) A consistent and conservative style for all shell scripts has been
3914 implemented. Basically, all shell string tests use the traditional
3915 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3916 to protect against bare null variable strings (ie: wrapping both
3917 sides with double quotes and prepending 'x'). 'x' was chosen
3918 because it's more universal and hopefully easier for old shell
3919 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3922 *) The status module now prints out both the main server generation as
3923 well as the generation of each process. Also, the vhost info is
3924 printed with '?notable'. [Jim Jagielski]
3926 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3927 and this makes its functions available to things in src/support.
3930 Changes with Apache 1.3.4
3932 *) Renamed macros status_drops_connection to ap_status_drops_connection
3933 and vestigial scan_script_header to ap_scan_script_header_err,
3934 mostly for aesthetic reasons. [Roy Fielding]
3936 *) The query switch "httpd -S" didn't exit after showing the
3937 vhost settings. That was inconsistent with the other query functions.
3940 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3941 filename to the end of the STANDARD_MODULE_STUFF. Its
3942 presence at the beginning prevented reporting of the filename
3943 for modules compiled before 1 January 1999. [Ken Coar]

3960 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3961 to build binary distributions. [Lars Eilebrecht]
3963 *) IndexOptions SuppressColumnSorting only turned off making
3964 the column headers anchors; you could still change the display
3965 order by manually adding a '?N=A' or similar query string to the
3966 URL. Now SuppressColumnSorting locks in the sort order so
3967 it can't be overridden this way. [Ken Coar]
3969 *) Added IndexOrderDefault directive to supply a default sort order
3970 for FancyIndexed directory listings. [Ken Coar] PR#1699
3972 *) Change the ap_assert macro to a variant that works on all platforms.
3973 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3975 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3976 search for an underscore on dlsym() (as it's already the case
3977 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3979 *) Small fix for mod_env.html: The module was documented as to be _not_
3980 compiled into Apache per default, although it _IS_ compiled into
3981 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3983 *) Instead of fixing a bug in the generation procedure for config.status (a
3984 backslash was missing) we remove the bug together with it's complete
3985 context because the special cases of the past can now no longer occur
3986 because of the recent magic for the --with-layout default.
3987 [Ralf S. Engelschall] PR#3590
3989 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3990 making sure the src/support/ tools are _forced_ to be build last (they
3991 depend on other libraries).
3992 [Markus Theissinger <markus.theissinger@gmx.de>]
3994 *) Fix installation procedure: Now that os-inline.c is actually used (a
3995 recently fixed bug prevented this) we need to also install os-include.c
3996 in addition to os.h into the PREFIX/include/ location or building of
3997 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3999 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
4000 allow us to distinguish between a garbled DSO (or even a file which isn't
4001 an Apache module DSO at all) and a DSO which doesn't match the current
4002 Apache API. [Ralf S. Engelschall] PR#3152
4004 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
4005 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
4006 match case insensitive (this especially avoids nasty patterns like
4007 `[tT][eE][sS][tT]'). Second two additional internal map functions
4008 `escape' and `unescape' were added which can be used to escape/unescape
4009 to/from hex-encodings in URLs parts (this is especially useful in
4010 combination with map lookups).
4011 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
4013 *) Renamed the macro escape_uri() to ap_escape_uri() which was
4014 forgotten (because it was a macro) in the symbol renaming process.
4015 [Ralf S. Engelschall]
4017 *) Fix some inconsistencies related to the scopes of directives. The only
4018 user visible change is that the directives `UseCanonicalName' and
4019 `ContentDigest' now use the (more correct) `Options' scope instead of
4020 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
4022 *) Using DSO, the Server token was being mangled. Specifically, the
4023 module's token was being added first before the Apache token. This
4024 has been fixed. [Jim Jagielski]
4026 *) Major overhaul of mod_negotiation.c, part 2.
4027 - properly handle "identity" within Accept-Encoding.
4028 - allow encoded variants in RVSA negotiation and let them appear in
4029 the Alternates field using the non-standard "encoding" tag-list.
4030 - fixed both negotiation algorithms so that an explicitly accepted
4031 encoding is preferred over no encoding if "identity" is not
4032 included within Accept-Encoding.
4033 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4034 of large substring sequences.
4035 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4038 *) Major overhaul of mod_negotiation.c, part 1.
4039 - cleanups to mod_negotiation comments and code structure
4040 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4041 support for everything in the upcoming HTTP/1.1
4042 revision (draft-ietf-http-v11-spec-rev-06.txt).
4043 - language tag matching also handles tags with more than 2
4045 - empty Accept, Accept-Language, Accept-Charset headers are
4046 processed correctly; previously an empty header would make all
4047 values acceptable instead of unacceptable.
4048 - allowed for q values in Accept-Encoding
4049 - added support for transparent content negotiation (rfc2295 and
4050 rfc2296) (though we do not implement all features in these drafts,
4051 e.g. no feature negotiation). Removed old experimental version.
4052 - implemented 'structured entity tags' for better cache correctness
4053 (structured entity tags ensure that caches which can deal with Vary
4054 will (eventually) be updated if the set of variants on the server
4056 - this involved adding a vlist_validator element to request_rec
4057 - this involved adding the ap_make_etag() function to the global API
4058 - modified guessing of charsets used by Apache negotiation algorithm
4059 to guess 'no charset' if the variant is not a text/* type
4060 - added code to sort multiviews variants into a canonical order so that
4061 negotiation results are consistent across backup/restores and mirrors
4062 - removed possibility of a type map file resolving to another type map
4063 file as its best variant
4064 [Koen Holtman, Roy Fielding, Lars Eilebrecht] PR#3451, 3299, 1987
4066 *) RFC2396 allows the syntax http://host:/path (with no port number)
4067 but the proxy disallowed it (ap_proxy_canon_netloc()).
4068 [David Kristol <dmk@bell-labs.com>] PR#3530
4070 *) When modules update/modify the file name in the configfile_t structure,
4071 syntax errors will report the updated name, not the original one.

4074 *) Correct some filename case assumptions from WIN32 to
4075 CASE_BLIND_FILESYSTEM. [Brian Havard <brianh@kheldar.apana.org.au>]
4077 *) For %v log ServerName regardless of the UseCanonicalName
4078 setting (similarly for %p). [Dean Gaudet]
4080 *) Configure was initializing the variables $OSDIR, $INCDIR and $SHELL
4081 rather late (too late for some invocations of TestCompile).
4082 This improves the make environment available to TestCompile and
4083 the *.module scripts. [Martin Kraemer]
4085 *) The hashbang emulation code in ap_execve.c would interpret
4086 #!/hashbang/scripts correctly, but failed to fall back to a
4087 standard shell for scripts which did NOT start with #!
4088 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4090 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4093 *) Update APXS manual page: some -q option arguments were missing
4094 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4096 *) Cleanup the command line options: `-?' was documented to show
4097 the usage list but does it with an error because `?' is not a valid
4098 command. OTOH a lot of users expect `-h' to print such a usage list and
4099 instead are annoyed for ages by our huge unreadable list of directives.
4100 So we now changed the command line options this way:
4102 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4103 very similar to the popular linker option.
4105 Intent: while -l gives the small list of modules, -L now gives the
4106 large list of directives implemented by these modules. This is also
4107 consistent with -v (short version info) and -V (large version info).
4109 Intent: it's now the expected option ;-)
4110 The manual page was adjusted accordingly.
4111 [Ralf S. Engelschall] PR#2714
4113 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4114 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4116 *) Removed recently introduced bugs and disfigurements in APACI:
4117 o fixed argument line processing: using $args was broken: It was not
4118 initialized and using args="$args $apc_option" and even args="$args
4119 \"$apc_option\"" fails in the second processing round for any arguments
4120 containing whitespaces. The only correct way is to use the construct
4121 "$@" (but not possible here) or iterate _both_ times over the implicit
4122 argument line (no argument to for-loop) which is what we now use.
4123 o make --with-layout=Apache the default without creating
4124 redundancy (copying the --with-layout block in the argument parsing
4125 loop). We achieve this by using the "$@" construct together with the
4126 `set' command to prepend --with-layout=Apache to the command line in
4127 case --with-layout is not used.
4128 o fixed auto-suffix handling now that config.layout exists.
4129 Paths which are auto-suffixed are marked with a trailing plus sign in
4130 config.layout and every path now can be marked this way (not only the
4131 four paths for which we do it currently). Additionally the suffix is
4132 no longer a static one. Instead it's now `/<target>' where <target> is
4133 the argument of the --target option or per default `httpd'.
4134 o allow also tabs (and only spaces) where we match whitespaces
4135 o various fixes and cleanups related to used shell coding style
4136 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4137 o trimmed output of --help to fit into 80 columns
4138 [Ralf S. Engelschall]
4140 *) Added two new core API functions, ap_single_module_configure() and
4141 ap_single_module_init(), which are now used by mod_so to configure a module
4142 after loading. [Ralf S. Engelschall]
4144 *) PORT: Add defines for USE_FLOCK_SERIALIZED_ACCEPT and
4145 SINGLE_LISTEN_UNSERIALIZED_ACCEPT to NetBSD/OpenBSD section
4146 of ap_config.h to allow serialized accept for multiport listens.
4147 [Roy Fielding, Curt Sampson] PR#3120
4149 *) PORT: Fixed a misplaced #endif for NetBSD/OpenBSD section
4150 of ap_config.h that would skip several defines if DEFAULT_GROUP
4151 was overridden. [Roy Fielding]
4153 *) PORT: The I86 version of DGUX has support for strncasecmp and
4154 strcasecmp, so allow it in ap_config.h. [Amiel Lee Yee] PR#3247
4156 *) Fix ordering of definitions in ap_config.h so that ap_inline is
4157 defined before it might be used. [Victor Khimenko]
4159 *) PORT: Add Dynamic Shared Object (DSO) support for BSDI (v4.0).
4160 [Tom Serkowski <tks@bsdi.com>] PR#3453
4162 *) Make generation of src/Configuration.apaci more robust: It failed to
4163 differenciate between modules when one module name was a postfix of
4164 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4165 just XXX (think about totally non-standard names like "apache_ssl", too).
4166 [Ralf S. Engelschall] PR#3380
4168 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated
4169 since 1.3b7) and make whitespace handling more robust (it failed horrible
4170 when whitespaces were present in the arguments of -D options).
4171 [Ralf S. Engelschall] PR#3240
4173 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4174 creates an external package shadow tree in DIR before the local build
4175 shadow tree is generated under DIR. This way one can have the extracted
4176 Apache distribution tree read-only on NFS or CDROM and still build Apache
4177 from these sources. An automatically triggered VPATH-like mechanism is
4178 provided through the TOP variable, too.

4192 and the usage page was inconsistent with the functionality and manpage.
4193 [Ralf S. Engelschall]
4195 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
4196 They can occur multiple times and their arguments (`xxx') are passed AS
4197 IS to the compiler/linker command. [Ralf S. Engelschall]
4199 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4200 procedure of mod_rewrite: very long keys were truncated.
4201 [Ralf S. Engelschall]
4203 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4204 identifier, currently "Apache" and "GNU" are pre-defined in the file
4205 config.layout. Custom layouts are possible by using FILE:ID as the
4206 argument where the layout ID is taken from FILE.
4208 The config.layout file consists of <Layout ID>..</Layout> sections
4209 where inside those sections "path_variable: path_value" pairs can be
4210 specified. These lines are converted to path_variable='path_value'.
4212 *) Add a DefaultLanguage directive so that files missing a language
4213 extension (e.g., .fr, .de) can be labelled as being some other
4214 default language. DefaultLanguage can appear in <Directory> and
4215 <Files> containers as well as .htaccess files. [Paul Sutton]
4218 *) Fix TARGET configuration when configuring and installing using
4219 APACI configure. TARGET now defines the basename of the configuration
4220 file, startup script, manual page, etc. log_error_core() now reports
4221 the server binary name given by argv[0]. TARGET can now also be defined
4222 with --target=TARGET parameter passed to APACI configure.

4330 in the Configuration[.apaci] file. Two special and important variants are
4331 supported for the option argument: first BEGIN:foo which permutes module
4332 mod_foo with the begin of the module list, i.e. it `moves' the module to
4333 the begin of the list (gives it lowest priority). And second foo:END
4334 which permutes mod_foo with the end of the module list, i.e. it `moves'
4335 the module to the end of the list (gives it highest priority).

4414 of the protocol processing, which is extra nice because it works
4415 between continuation lines, is almost no cost in the normal case
4416 of no extra whitespace, and saves memory. [Roy Fielding]

4542 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4543 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4544 platform to make the braindead HPUX linker happy. Notice, for the module
4545 DSOs we don't have to use this, because these are loaded manually (and
4546 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

4557 *) Make PrintPath work generically instead of having one version
4558 strictly for OS/2. [Jim Jagielski, Brian Havard]
4560 *) Fix the recently introduced C header file checking: We now use the C
4561 pre-processor pass only (and no longer the complete compiler pass) to
4562 determine whether a C header file exists or not. Because only this way
4563 we're safe against inter-header dependencies (which caused horrible
4564 portability problems). The only drawback is that we now have a CPP
4565 configuration variable which has to be determined first (we do a similar
4566 approach as GNU Autoconf does here). When all fails the user still has
4567 the possibility to override it manually via APACI or src/Configuration.
4568 As a fallback for the header check itself we can directly check the
4569 existance of the file under /usr/include, too.

4603 -msym is just to optimize the DSO statup time a little bit it's safe and
4604 best when we leave it out now. [Ralf S. Engelschall] PR#2969

4607 functions: First all three functions no longer fail on strings containing
4608 "%" chars and second ap_log_printf() no longer does a double-formatting
4609 (instead it directly passes through the message to be formatted to the
4610 real internal formatting function). [Ralf S. Engelschall] PR#2941
4612 *) Allow "Include" directives anywhere in the server config
4613 files (but not .htaccess files). [Ken Coar] PR#2727
4615 *) The proxy was refusing to serve CONNECT requests except to
4616 port 443 (https://) and 563 (snews://). The new AllowCONNECT
4617 directive allows the configuration of the ports to which a
4618 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4620 *) mod_expires will now act on content that is not sent from a file
4621 on disk. Previously it would never add an Expires: header to
4622 any response that did not come from a file on disk; the only
4623 case where it still doesn't (and can't) add one for that type of
4624 content is if you are using a modification date based setting.

4636 *) Recognize lowercase _and_ uppercase `uname' results under

4639 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4640 a common problem of (mis-administrated?) IIS servers, make the apache
4641 proxy immune to these errors (and ignore the duplicates, but log
4642 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4644 *) The <IfModule and <IfDefine block starting directives now only
4645 allow exactly one argument. Previously, the optional negation
4646 character '!' could be separated by whitespace without a syntax
4647 error being reported, albeit defeating the IfModule functionality
4648 (enclosed directives would ALWAYS be executed). By using the
4649 stricter syntax, these hard-to-track errors can be avoided.
4652 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4653 cause the standalone FancyIndexing directive to logically OR
4654 into any existing IndexOptions settings rather than wiping
4655 them out. [Ken Coar]
4657 *) Changes in ftp proxy: make URL parsing simpler by using the
4659 + Add display of the "current directory" in cases where it's
4660 different from the supplied path (e.g., ftp://user@host/ lives
4661 in /home/user, not in /, therefore clicking on "../" in the
4662 starting directory might send us to /home/).
4663 + When ftp login fails, (esp. when a user name was part of the
4664 URL already), we now return [401 Unauthorized ] to allow the
4665 browser to pop up an authorization dialog. This makes passwords
4666 slightly less visible (they don't appear in the regular log files)
4667 and implements a functionality that other www proxy servers
4671 *) Triggered by the recent "Via:" header changes, the proxy module would
4672 dump core for replies with invalid headers (e.g., duplicate
4673 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4674 core dump is avoided. Also, broken replies are not cached.
4675 [Martin Kraemer] PR#2914
4677 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4678 plop gmon.out profile data for each child [Doug MacEachern]

4682 [Yves Arrouye <yves@apple.com>] PR#2866
4684 *) Replace the inlined information grabbing stuff for the configuration
4685 adjustment feature (no --without-confadjust) with calls to a new helper
4686 script `buildinfo.sh' which is both more flexible and already proofed to
4687 be more robust against platform differences. This mainly fixes the
4688 recently occured ``sed: command garbled: ...'' problems.

4709 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4710 5 to 10 because there are some users out there who always have 5 to 8
4711 variables in one RewriteRule and had to patch mod_rewrite.h for every
4712 release. So 15 should be now more than enough, even for them. (I never
4713 needed more than 4 in my RewriteRules ;-)
4714 [Ralf S. Engelschall]
4716 *) Make the proxy generate and understand Via: headers

4723 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844

4733 *) Extend the output of the -V switch to include the paths of all

4735 compile time, for least astonishment of the user.
4738 *) When READing a request in ExtendedStatus mode, the "old"
4739 vhost, request and client information is not displayed.
4742 *) STATUS is no longer available. Full status information now
4743 run-time configurable using the ExtendedStatus directive.
4746 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4747 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4748 a function which can be used to perform bulk update operations
4749 on tables in a more efficient manner. [Dean Gaudet]
4751 *) SECURITY: Added compile-time and configurable limits for
4752 various aspects of reading a client request to avoid some simple
4753 denial of service attacks, including limits on maximum request-line
4754 size (LimitRequestLine), number of header fields (LimitRequestFields),
4755 and size of any one header field (LimitRequestFieldsize). Also added
4756 a configurable directive LimitRequestBody for limiting the size of the
4757 request message body. [Roy Fielding]

4760 STATUS not defined. [Jim Jagielski]

4775 *) The 'status' module will now show the process pid's and their
4776 state even without full STATUS accounting. [Jim Jagielski]
4778 *) Restore the client IP address to the error log messages, this
4779 was lost during the transition from 1.2 to 1.3. Add a new
4780 function ap_log_rerror() which takes a request_rec * and
4781 formats it appropriately. [Dean Gaudet] PR#2661
4783 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4784 whitespace in input lines -- including within quoted strings.
4786 but leading and trailing whitespace should continue to be
4787 stripped [Martin Kraemer]
4789 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4790 the ugly use of an env. variable and use command-line args for
4791 alternate $PATH. Make more like advanced 'type's as well.
4794 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
4795 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis

4798 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
4800 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
4801 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
4802 directory was renamed to src/os/os2/ for consistency.
4803 [Brian Havard, Ralf S. Engelschall]
4805 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4806 files (here modules) against other DSO files (here shared libraries).
4807 This is done by determining a subset of LIBS which can be safely used for
4808 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4809 disabled for all platforms to avoid problems with this (experimental)
4810 rule. But we provide it now for those people how ran into problems and
4811 want to came out by forcing linking against DSOs.

4933 is a valid directory. The failure to do this caused certain
4934 ServerRoot settings (eg. "ServerRoot /apache") to be improperly
4935 rejected. [Marc Slemko]
4937 *) Global renaming of C header files to both get rid of conflicts with third
4938 party packages and to again reach consistency:
4939 1. conf.h -> ap_config.h
4940 2. conf_auto.h -> ap_config_auto.h \ these are now merged
4941 3. ap_config.h -> ap_config_auto.h / in the config process
4942 4. compat.h -> ap_compat.h
4943 5. apctype.h -> ap_ctype.h
4944 Backward compatibility files for conf.h and compat.h were created.
4946 *) mod_mmap_static will no longer take action on requests unless at
4947 least one "mmapfile" directive is present in the configuration.
4948 This experimental module has to do some black magic to operate
4949 inside the current API and thus creates side-effects for other
4950 modules under some circumstances.

4953 *) Add conservative ticks around more egrep arguments in top-level configure
4954 to avoid problems under brain-dead platforms like Digital UNIX (OSF1).

4957 *) mod_rewrite created RewriteLock files under the UID of the parent
4958 process, thus the child processes had no write access to the files.
4959 Now a chown() is done on the file to the uid of the children,
4960 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
4962 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
4963 TestCompile) instead of defining them manually in conf.h based on less
4964 accurate platform definitions. This way we no longer have to fiddle with
4965 OS-type and/or OS-version identifiers to discover whether a system header
4966 file exists or not. Instead we now directly check for the existence of
4967 those esoteric ones.

4975 modules to load their own modules dynamically. This improves mod_perl

5067 these are treated by Win32 as if they are ".." but are not detected by

5069 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5071 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses

5090 these configuration adjustments.

5099 as <IfModule>..</IfModule> sections) which can be used to skip or process
5100 contained commands dependend of ``-D PARAMETER'' options on the command
5101 line. This can be used to achieve logical conditions like <IfDefine
5102 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)

5104 modules via LoadModule, etc. [Ralf S. Engelschall]

5115 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5116 in top-level configure script to avoid sed fails on some platforms (for
5117 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5118 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5120 *) Improve performance of directory listings (mod_autoindex) by comparing
5121 integer keys (last-modified and size) as integers rather than converting
5122 them to strings first. Also use a set of explicit byte tests rather
5123 than strcmp() to check for parent directory-ness of an entry. Oh, and
5124 make sure the parent directory (if displayed) is *always* listed first
5125 regardless of the sort key. Overall performance winnage should be good
5126 in CPU time, instruction cache, and memory usage, particularly for large
5127 directories. [Ken Coar]
5129 *) Add a tiny but useful goody to APACI's configure script: The generation
5130 of a config.status script (as GNU Autoconf does) which remembers the used
5131 configure command and hence can be used to restore the configuration by
5132 just re-running this script or for remembering the configuration between
5134 [Ralf S. Engelschall]
5136 *) Add httpd -t (test) option for running configuration syntax tests only.
5137 If something is broken it complains and exits with a return code
5138 non-equal to 0. This can be used manually by the user to check the Apache
5139 configuration after editing and is also automatically used by apachectl
5140 on (graceful) restart command to make sure Apache doesn't die on restarts
5141 because of a configuration which is now broken since the last (re)start.
5142 This way `apachectl restart' can be used inside cronjobs without having
5143 to expect Apache to be falling down. Additionally the httpd -t can be run
5144 via `apachectl configtest'.

5296 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5297 was updated to use the normal apache error processing, thereby allowing
5298 proxy errors to be treated by ErrorDocument's as well. For this
5299 purpose, a new module-to-core communication variable "error-notes"
5300 was introduced; the proxy (and possibly other modules) communicates
5301 its error text using this variable. Its content is copied to a new
5302 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5303 The old proxy special error routine ap_proxy_log_uerror()

5382 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5384 *) The Makefiles assumed that DSO files are build via $(LD). This
5385 is broken for two reasons: First we never defined at least LD=ld
5386 somewhere to make sure this works (it was silently assumed that most Make
5387 provide a built-in LD definition - ARGL!) and second using the generic LD
5388 variable is not the truth. Instead a special variable named LD_SHLIB is
5389 reasonable because although "ld" is usually the default, the command for
5390 building DSO files can be "libtool" or even "cc" on some systems.

5407 - make OSDIR also automatically be relative to src/ like INCDIR
5408 - SUBDIRS is now generated in src/Makefile only and not in
5409 Makefile.config because it is a local define for this location.
5410 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5411 any Makefile but make sure that at least the "-K inline" is kept in
5413 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5414 - updated the dependencies theirself
5415 - removed not existing SHLIB variable from "clean" targets
5416 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5417 already exists and OBJS_PIC are also just plain objects and have not
5418 directly to do with "shared" things. The only difference is that they
5419 contain PIC. So OBJS_PIC is the more canonical name.
5420 - Updated the Makefile-dependency lines for OBJS_PIC
5421 - Removed the Makefile-dependency line in Configure to avoid double
5423 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5424 of xxx.lo as GNU libtool does with its PIC objects
5425 - reduce local complexity in modules Makefile.tmpl by moving the last
5426 existing target "depend" to the generation section in Configure, too.
5427 - removed the historical $(SPACER) which was used in the past together
5428 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5429 is no longer needed.
5430 - force the build and run of the gen_xxx programs under main/ as the
5431 first step before building the objects because it looks cleaner
5432 [Ralf S. Engelschall]
5434 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5437 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5440 *) WIN32: Don't force ISAPI headers to finish with \n.
5441 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5443 *) When opening "configuration" files (like httpd.conf, htaccess
5444 and htpasswd), Apache will not allow them to be non-/dev/null
5445 device files. This closes a DoS hole. At the same time,
5446 we use ap_pfopen to open these files to handle timeouts.
5447 [Jim Jagielski, Martin Kraemer]
5449 *) Apache will now log the reason its httpd children exit if they exit
5450 due to an unexpected signal. (It requires a new porting define,
5451 SYS_SIGLIST, which if defined should point to a list of text
5452 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5454 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5455 like WIN32. Before, Win32 CGI's could have had sporadic failures
5456 if a chdir call from one thread was made between another chdir call
5457 and a spawn in another thread. So, for now don't chdir for CGI scripts
5458 in WIN32. The current CGI "spec" is unclear as to whether it's
5459 necessary. Long-term fix is to either serialize the chdir/spawn combo
5460 or use WIN32 native calls to spawn a process. This temp fix was
5461 necessary to remove this as a showstopper for 1.3's release.
5464 *) Cleanup the suEXEC support in APACI and make it more safe:
5465 1. Add big fat hint in INSTALL about risks and to read the
5466 htdocs/manual/suexec.html document before using the suexec-related
5468 2. Make sure the user has at least provided one --suexec-xxxx option
5469 (specifies suEXEC parameters) in addition to --enable-suexec option.
5470 If only --enable-suexec is given APACI stops with a hint to INSTALL
5471 and htdocs/manual/suexec.html documents.
5472 3. Provide two additional --suexec-xxxx options to make the suEXEC
5473 configuration complete (especially for package maintainers who else
5474 had to patch the source tree) by providing ways to configure minimal
5475 UID/GID and safe PATH, too.
5476 [Ralf S. Engelschall]
5478 *) Cleanup of the `configure --shadow' process:
5479 - make sure the configure script creates its temporary files in the
5480 shadow tree to avoid conflicts with parallel configure runs
5481 - removed unnecessary option "-r" from "rm" call for Makefiles
5482 - make sure the configure scripts creates the shadow-wrapper Makefile
5483 only when no shadow trees already exists
5484 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5485 when no more shadow trees exists
5486 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5487 as fast (in the past it needed 70sec, now it runs just 38sec)
5488 - make sure CVS does not complain about the created files
5489 Makefille.<gnutriple> and directories src.<gnutriple>
5490 [Ralf S. Engelschall]
5492 *) Added the ap_add_version_component() API routine and the
5493 AddVersionPlatform core directive. The first allows modules to
5494 declare themselves in the Server response header field value,
5495 augmenting the SERVER_SUBVERSION define in the Configuration file
5496 with run-time settings (more useful in a loadable-module environment).
5497 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5498 into the server version string. [Ken Coar] PR#2056
5500 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5503 *) Emit the "Accept-Range" header for the default handler.
5504 [Brian Behlendorf] PR#1464
5506 *) Add a note to httpd.conf-dist that apache will on some systems fail
5507 to start when the Group # is set to a negative or large positive value.
5510 *) Make sure the module execution order is correct even when some modules
5511 are loaded under runtime (`LoadModule') via the DSO mechanism:
5512 1. The list of loaded modules is now a dynamically allocated one
5513 and not the original statically list from modules.c
5514 2. The loaded modules are now correctly setup by LoadModule for
5515 later use by the AddModule command.
5516 3. When the DSO mechanism for modules is used APACI's `install'
5517 target now enables all created `LoadModule' lines per default because
5518 this is both already expected by the user _and_ needed to avoid
5519 confusion with the next point and reduces the Makefile.tmpl complexity
5520 4. When the DSO mechanism for modules is used, APACI's `install'
5521 target now additionally makes sure the module list is reconstructed
5522 via a complete `ClearModuleList+AddModule...' entry.
5523 5. The support tool `apxs' now also makes sure an AddModule command
5524 is added in addition to the LoadModule command.
5525 6. The modules.c generation was extended to now contain two
5526 comments to make sure no one is confused by the confusing terminology
5527 of loading/linking (we use load=link+load & link=activate instead of
5528 the obvious load=activate & link=link :-( )
5529 This way now there is no longer a difference under execution time between
5530 statically and dynamically linked modules.

5533 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5534 Big Symbol Renaming. [Ralf S. Engelschall]
5536 *) Add a comment to mod_example.c showing the format of a FLAG command
5539 *) Standardized the time format in mod_status to match that of other
5540 places in the code (e.g. DATE_GMT). PR#1551
5542 *) Fix handling of %Z in timefmt strings for those platforms with no time
5543 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5546 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5547 feature compatible with 'UseCanonicalName off' by changing
5548 r->server->server_hostname to ap_get_server_name(). And I changed some
5549 functions which use r->server->port to use ap_get_server_port() instead,
5550 because if there's no Port directive in the config r->server->port is 0.
5553 *) get/set_module_config are trivial enough to be better off inline. Worth
5554 1.5% performance boost. [Dean Gaudet]
5556 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5557 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5560 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5561 the task environment to the unprivileged User id. Otherwise CGI scripts
5562 would have a way to gain super user access. [Martin Kraemer]
5564 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5565 absolute path, only log base name of logging source as is done
5566 in unix. [Martin Kraemer]
5568 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5569 the encoding type from the Accept-Encoding header (if it's there)
5570 and use it in the response, as that's probably what it'll be expecting.
5571 [Ronald.Tschalaer@psi.ch]
5573 *) Fix to mod_alias: translate_alias_redir is dealing with
5574 a URI, not a filename, so the check for drive letters for win32
5575 and emx is not necessary. [Dean Gaudet]
5577 *) WIN32: Allow .cmd as an executable extension.

5583 *) Child processes can now "signal" (by exiting with a status
5584 of APEXIT_CHILDFATAL) the parent process to abort and
5585 shutdown the server if the error in the child process was
5586 fatal enough. [Jim Jagielski]
5588 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5589 [Jim Jagielski] PR#2112
5591 *) Make sure the referer_log and agent_log entries in the default httpd.conf

5595 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5597 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5600 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5601 Additionally the checks for finding the vendor DSO library were moved
5602 from mod_so.c to Configure because first it needs $PLAT etc. and second
5603 mod_so already uses an abstraction layer and does not fiddle with the
5604 vendor functions itself.
5605 [Jens-Uwe Mager, Ralf S. Engelschall]
5607 *) PORT: Some optimization defines for NetBSD
5608 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5610 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5611 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5613 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5614 AIX variants should work fine, too. Even AIX 3.x should work). This is
5615 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5616 which we put into a os/unix/os-dso-aix.c file.
5617 [Ralf S. Engelschall]
5619 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5620 that we should use NET_SIZE_T == int but the include files force size_t.
5621 [Ralf S. Engelschall]
5623 *) Fix two bugs in select() handling in http_main.c.
5626 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5627 is unset (as it is in situations like timeouts) where it is unclear
5628 whether errno is set or not. [Martin Kraemer]
5630 *) Just having APACI's localstatedir is too general and not enough for most
5631 of the systems. 1.3b6 again required manual APACI patches by package
5632 maintainers from RedHat and FreeBSD because for their filesystem layout a
5633 little bit more flexibility in configuring the paths is needed. Hence we
5634 provide three additional configure options (--runtimedir, --logfiledir,
5635 --proxycachedir) which now can be used for more granular adjustments if
5636 --localstatedir is not enough to fit the particular needs. As a nice
5637 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5638 [Ralf S. Engelschall]
5640 *) Make the install root for "make install" in APACI's Makefile overrideable
5641 by package authors. This way we are even more friendly to package
5642 maintainers (especially Debian and RedHat) who build for the real prefix
5643 via "configure --prefix=/<real>" but use a different local prefix via
5644 "make root=/tmp/apache install" for rolling the package without bristling
5645 the target location on their system.
5646 [Ralf S. Engelschall]
5648 *) Workaround sed limitations in APACI's configure script by now
5649 substituting in chunks of 50 commands (because for instance HPUX's vendor
5650 sed has a limit of max. 98 commands)

5653 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5654 [Ralf S. Engelschall] PR#2140
5656 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5657 RENAMING process because they are defined as pre-processor macros instead
5658 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5659 [Ralf S. Engelschall]
5661 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5662 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5663 [Ralf S. Engelschall] PR#2139
5665 *) Various bugfixes and cleanups for the APACI configure script:
5666 o fix IFS handling for _nested_ situation
5667 o fix Perl interpreter search: take first one found instead of last one
5668 o fix DSO consistency check
5669 o print error messages to stderr instead of stdout
5670 o add install-quiet for --shadow situation to Makefile stub
5671 o reduce complexity by avoiding sed-hacks for rule and module list loops

5674 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5676 *) Make sure the input field separator (IFS) shell variable is explicitly
5677 initialized correctly before _every_ `for' loop and also restored after
5678 the loops. [Ralf S. Engelschall]
5680 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5681 `magic' files from an existing Apache installation. Because people often
5682 customize these for own MIME and content types.

5688 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5689 [Ralf S. Engelschall] PR#2105
5691 *) Let "configure" clear out the users parameters (provided as shell

5694 [Ralf S. Engelschall] PR#2101
5696 *) Provide backward compatibility from some old src/Configuration.tmpl
5697 parameter names to the canonical Autoconf-style shell variable names. For

5706 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5707 second by making sure the "avoid-bristling-suffix" /apache is not
5708 appended to sysconfdir, datadir, localstatedir and includedir when

5718 [Ralf S. Engelschall] PR#2089
5720 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5722 *) If you start apache with the -S command line option it will dump
5723 out the parsed vhost settings. This is useful for folks trying
5724 to figure out what is wrong with their vhost configuration.
5725 (Other dumps may be added in the future.) [Dean Gaudet]
5727 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5728 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5731 *) Because /usr/local/apache is the default prefix the ``configure
5732 --compat'' option no longer has to set prefix, again. This way the
5733 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5735 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5736 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5737 to avoid "discard const" warnings. [Ralf S. Engelschall]
5739 *) If a specific handler is set for a file yet the request still
5740 ends up being handled by the default handler, log an error
5741 message before handling it. This catches things such as trying
5742 to use SSIs without mod_include enabled. [Marc Slemko]
5744 *) Fix error logging for the startup case where ap_log_error() still uses
5745 stderr as the target. Now the default log level is honored here, too.
5746 [Ralf S. Engelschall]
5748 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5749 long" errors when generating the MODULES entry for src/Makefile
5750 [Ben Hyde, Ralf S. Engelschall]
5752 *) Make sure src/Configure doesn't complain about the old directory
5753 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5755 Changes with Apache 1.3b6
5757 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5759 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5760 interface via the similar but proprietary HP/UX shl_xxx-style system
5761 calls. [Ralf S. Engelschall]
5763 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5764 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5765 Make. [Ralf S. Engelschall]
5767 *) ++++ THE BIG SYMBOL RENAMING ++++
5768 To avoid symbol clashes with third-party code compiled into the server,
5769 we globally applied the prefix "ap_" to the following classes of
5771 - Apache provided general functions (e.g., ap_cpystrn)
5772 - Public API functions (e.g., palloc, bgets)
5773 - Private functions which we can't make static (because of
5774 cross-object usage) but should be (e.g., new_connection)
5775 For backward source compatibility a new header file named compat.h was
5776 created which provides defines for the old symbol names and can be used
5777 by third-party module authors.
5780 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5781 problem under SVR4 is that there is no command flag to force the linker
5782 to export the global symbols of the httpd executable therewith they are
5783 available to the DSO's. Instead of problematic hacks like creating a
5784 dummy.so file (containing dummy references to all global symbols) the
5785 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5786 Placing the Apache core code itself into a DSO library named libhttpd.so.
5787 This way the global symbols _HAVE_ to be exported and thus are available
5788 to any manually loaded DSO's under runtime. To reduce the impact to the
5789 user to null we go even further and create a stub httpd executable which
5790 automatically keeps track of the DSO library loading itself and thus
5791 hides the complete mechanism from the user. Although the generation of
5792 this DSO library is automatically triggered for platforms which
5793 essentially need it (mostly all SVR4-derivates) it can be also enabled
5794 manually via the Rule SHARED_CORE. This can be interesting in the future
5795 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5796 features like graceful upgrades, or whatever.
5797 [Ralf S. Engelschall, Martin Kraemer]
5799 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5801 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5802 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5803 conventions while "clean" removes only stuff created by "all" targets,
5804 "distclean" additionally removes the stuff from the configuration
5805 process. This way "make distclean" (hence the name) provides a fresh
5806 source tree as it was for distribution.
5807 [Ralf S. Engelschall]
5809 *) Allow top-level (APACI) Makefile to break on build errors
5810 the same way the src/ subtree Makefiles breaks on them by replacing the
5811 initial APACI sed-subdir-display-kludge with a more clean
5812 variable-passing-solution: variable SDP can optionally hold the subdir
5813 prefix which is consistently used for displaying the subdir movement.
5814 This way even the top-level Makefile can stop correctly on errors as the
5815 user expects. [Ralf S. Engelschall]
5817 *) Fixed ordering of argument checks for RewriteBase directive.
5818 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5820 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5821 indicating that a module is being compiled for dynamic loading. Also
5822 remove #define IS_MODULE from modules and add SHARED_MODULE define
5823 to the mak/dsp files. [Alexei Kosut]
5825 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5826 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5828 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5830 *) Add documentation file and src/Configuration.tmpl entry for the
5831 experimental mod_mmap_static module. Because although it is and marked as
5832 an experimental one it is distributed and thus should be documented and
5833 prepared for configuration the same way as all others modules.
5834 [Ralf S. Engelschall]
5836 *) Add query (-q) option to apxs support tool to be able to manually query
5837 specific settings from apxs. This is needed for instance when you
5838 manually want to access Apache's header files and you need to assemble
5839 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5840 [Ralf S. Engelschall]
5842 *) Now src/Configure uses a fallback strategy for the shared object support
5843 on platforms where no explicit information is available: If a Perl
5844 installation exists we ask it about its shared object support and if it's
5845 the dlopen-style one we shamelessly guess the compiler and linker flags
5846 for creating shared objects from Perls knowledge. Of course, the user is
5847 warning about what we are doing and informed that he should send us
5848 the guessed flags when they work. [Ralf S. Engelschall]
5850 *) Provide APACI --without-support option to be able to disable the build
5851 and installation of the support tools from the src/support/ area.
5852 Although its useful to have these installed per default we should provide
5853 a way to compile and install without them for backward-compatibility.
5854 [Ralf S. Engelschall]
5856 *) Add of the new APache eXtenSion (apxs) support tool for building and
5857 installing modules into an _already installed_ Apache package through the
5858 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5859 this approach actually doesn't need the Apache source tree. The
5860 (APACI-installed) server package is enough, because this now includes the
5861 Apache C header files (PREFIX/include) and the new APXS tool
5862 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5863 module authors to build their Apache modules _OUTSIDE_ the Apache source
5864 tree while avoiding them to fiddle around with the totally platform
5865 dependend way of compiling DSO files. The tool supports all ranges of
5866 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5867 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5868 on-the-fly generate a minimalistic Makefile and sample module for the
5869 first step to provide both a quick success event and to demonstrate the
5870 APXS mechanism to module authors. [Ralf S. Engelschall]
5872 *) Fix core dumps in use of CONNECT in proxy.
5873 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5875 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5876 so that users have examples of how CustomLog can be used.
5879 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5880 the Apache distribution tree. Until Apache 1.3 there was no real
5881 out-of-the-box batch-capable build and installation procedure for the
5882 complete Apache package. This is now provided by a top-level "configure"
5883 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5884 to provide a GNU Autoconf-style frontend which is capable to both drive
5885 the old src/Configure stuff in batch and additionally installs the
5886 package with a GNU-conforming directory layout. Any options from the old
5887 configuration scheme are available plus a lot of new options for flexibly
5888 customizing Apache. [Ralf S. Engelschall]

5905 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5906 a generic printf-style routine that can call arbitrary output
5907 routines. Use this to replace http_bprintf.c. Add new routines
5908 psprintf(), pvsprintf() which allocate the exact amount of memory
5909 required for a string from a pool. Use psprintf() to clean up
5910 various bits of code which used ap_snprintf()/pstrdup().
5913 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5914 ap_snprintf() has different semantics and formatting codes than
5915 snprintf(). [Dean Gaudet]
5917 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5918 is necessary on at least Solaris where the /etc/rc?.d scripts
5919 are run with these signals ignored, and "SIG_IGN" settings are
5920 maintained across exec().

5948 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5949 therefore not exposed to %2F -> '/' translations and 2) the request
5950 is a proxy request, so we're not dealing with a local resource anyway.
5951 Without this, the proxy would fail to work for any URL's with
5952 %2f in them (occurs quite often in
5953 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]

5970 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5971 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old

5985 document our stuff a little bit more and to be able to do really
5986 Unix-like installations ;-) [Ralf S. Engelschall]
5988 *) Major cleanups to the Configure script to make it and its generated
5989 Makefiles again readable and maintainable: add SRCDIR option, removed
5990 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5991 generated sections, consequently added Makefile headers with inheritance
5992 information, added subdir movement messages for easier following where
5993 the build process currently stays (more verbose then standard Make, less
5994 verbose than GNU make), same style to comments in the Configure script,
5995 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5997 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5998 from the ZeusBench benchmarking program and can be used to determine the

6022 *) Clean up some undocumented behavior of mod_setenvif related to
6023 "merging" two SetEnvIf directives when they match the same header
6024 and regex. Document that mod_setenvif will perform comparisons in
6025 the order they appear in the config file. Optimize mod_setenvif by
6026 doing more work at config time rather than at runtime.
6029 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
6030 to allow for modules to overrule them and to reduce redefinition
6031 warnings [Jim Jagielski]
6033 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6036 *) Making the hard-coded cross-module function call mime_find_ct() (from
6037 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6038 checking is really called even for proxy requests except for URLs with
6039 HTTP schemes (because there we can optimize by not running the type
6040 checking hooks due to the fact that the proxy gets the MIME Content-type
6041 from the remote host later). This change cleans up mod_mime by removing
6042 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6043 especially unbundles mod_proxy and mod_mime. This way they both now can
6044 be compiled as shared objects and are no longer tied together.
6045 [Ralf S. Engelschall]
6047 *) util.c cleanup and speedup. [Dean Gaudet]
6049 *) API: Clarification, pstrndup() will always copy n bytes of the source

6057 port is in the appropriate range. [Ben Hyde]
6059 *) Performance improvements to invoke_handler().
6060 [Dmitry Khrustalev <dima@bog.msu.su>]
6062 *) Added support for building shared objects even for library-style modules
6063 (which are built from more than one object file). This now provides the
6064 ability to build mod_proxy as a shared object module. Additionally
6065 modules like mod_example are now also supported for shared object
6066 building because the generated Makefiles now no longer assume there is at
6067 least one statically linked module. [Ralf S. Engelschall]
6069 *) API: Clarify usage of content_type, handler, content_encoding,
6070 content_language and content_languages fields in request_rec. They
6071 must always be lowercased; and the strings pointed to shouldn't
6072 be modified (you must copy them to modify them). Fix a few bugs
6073 related to this. [Dean Gaudet]
6075 *) API: Clarification: except for RAW_ARGS, all command handlers can
6076 treat the char * parameters as permanent, and modifiable. There
6077 is no need to pstrdup() them. Clean up some needless pstrdup().
6080 *) Now mod_so keeps track of which module shared objects with which names
6081 are loaded and thus avoids multiple loading and unloading and irritating
6082 error_log messages. [Ralf S. Engelschall]
6084 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6085 environment variable in the apache core. But that tweaking interferes
6086 with mod_setenv. So don't tweak if the user has specified an explicit
6087 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

6097 *) Various improvements to the configuration and build support for compiling
6098 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6099 OSF1 support with GCC and vendor compilers was added. This way shared
6100 object support is now provided out-of-the-box for FreeBSD, Linux,
6101 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6102 [Ralf S. Engelschall]
6104 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6105 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6106 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6108 *) Fix one more special locking problem for RewriteMap programs in
6109 mod_rewrite: According to the documentation of flock(), "Locks are on
6110 files, not file descriptors. That is, file descriptors duplicated
6111 through dup(2) or fork(2) do not result in multiple instances of a lock,
6112 but rather multiple references to a single lock. If a process holding a
6113 lock on a file forks and the child explicitly unlocks the file, the
6114 parent will lose its lock.". To overcome this we have to make sure the
6115 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6116 the case by opening it in the child_init instead of the module_init API
6117 hook. [Ralf S. Engelschall] PR#1029
6119 *) Change to Location and LocationMatch semantics. LocationMatch no
6120 longer lets a single slash match multiple adjacent slashes in the
6121 URL. This change is for consistency with RewriteRule and
6122 AliasMatch. Multiple slashes have meaning in URLs that they do
6123 not have in (some) filesystems. Location on the other hand can
6124 be considered a shorthand for a more complicated regex, and it
6125 does match multiple slashes with a single slash -- which is
6126 also consistent with the Alias directive.

6129 *) Fix bug with mod_mime_magic causing certain files, including files
6130 of length 0, to result in no response from the server.
6133 *) The Configure script now generates src/include/ap_config.h which
6134 contains the set of defines used when Apache is compiled on a platform.
6135 This file can then be included by external modules before including
6136 any Apache header files in case they are being built separately from
6137 Apache. Along with this change, a couple of minor changes were
6138 made to make Apache's #defines coexist peacefully with any autoconf
6139 defines an external module might have. [Rasmus Lerdorf]
6141 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6142 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6143 chance by the API to initialize its per-server configuration and thus
6144 receives the wrong one from the main server. This is now avoided by
6145 remembering the server together with the config structure while
6146 configuring and later assuming there is no config when we see a
6147 difference between the remembered server and the one calling us.
6148 [Ralf S. Engelschall] PR#1790
6150 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6151 is automatically disabled under configure time when the dbm_xxx functions
6152 are not available. Second, two heavy source code errors in the DBM
6153 support code were fixed. This makes DBM RewriteMap's usable again after
6154 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6156 *) Now all configuration files support Unix-style line-continuation via
6157 the trailing backslash ("\") character. This enables us to write down
6158 complex or just very long directives in a more readable way. The
6159 backslash character has to be really the last character before the
6160 newline and it has not been prefixed by another (escaping) backslash.

6172 *) WIN32: Preserve trailing slash in canonical path (and hence
6173 in PATH_INFO). [Paul Sutton, Ben Laurie]
6175 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6176 depending on the rev of Solaris and what mixture of modules
6177 are in use. So it has been disabled, and Solaris is back to
6178 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6179 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6180 up static content only servers. Or it may fail unpredictably.

6183 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6186 *) API: Rewrite of absoluteURI handling, and in particular how
6187 absoluteURIs match vhosts. Unless a request is a proxy request, a
6188 "http://host" url is treated as if a similar "Host:" header had been
6189 supplied. This change was made to support future HTTP/1.x protocols
6190 which may require clients to send absoluteURIs for all requests.
6192 In order to achieve this change subtle changes were made to the API. In a
6193 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6194 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6195 by the core, modules must set it during the post_read_request or
6196 translate_names phase.
6198 Plus changes to the virtualhost test suite for absoluteURI testing.
6200 This fixes several bugs with the proxy proxying requests to vhosts
6201 managed by the same httpd.
6204 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6205 code from mod_rewrite. The vhost matching is now performed by a
6206 globally available function matches_request_vhost(). [Dean Gaudet]

6222 *) API: A new source module main/util_uri.c; It contains a routine
6223 parse_uri_components() and friends which breaks a URI into its component
6224 parts. These parts are stored in a uri_components structure called
6225 parsed_uri within each request_rec, and are available to all modules.
6226 Additionally, an unparse routine is supplied which re-assembles the URI
6227 components back to an URI, optionally hiding the username:password@ part
6228 from ftp proxy requests, and other useful routines. Within the structure,
6229 you find on a ready-for-use basis:
6230 scheme; /* scheme ("http"/"ftp"/...) */
6231 hostinfo; /* combined [user[:password]@]host[:port] */
6232 user; /* user name, as in http://user:passwd@host:port/ */
6233 password; /* password, as in http://user:passwd@host:port/ */
6234 hostname; /* hostname from URI (or from Host: header) */
6235 port_str; /* port string (integer representation is in "port") */
6236 path; /* the request path (or "/" if only scheme://host was given) */
6237 query; /* Everything after a '?' in the path, if present */
6238 fragment; /* Trailing "#fragment" string, if present */
6239 This is meant to serve as the platform for *BIG* savings in
6240 code complexity for the proxy module (and maybe the vhost logic).
6243 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6244 ${map:key}) available for all location where a string is created in
6245 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of

6247 possible expansions are consequently usable at all string creation
6248 locations. [Ralf S. Engelschall]

6253 completely overridden (default) or completely inherited (when
6254 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6285 type but with a special post-processing for the looked-up value: It
6286 parses it into alternatives according to `|' chars and then only one
6287 particular alternative is chosen randomly (this is an essential
6288 functionality needed for balancing between backend-servers when using
6289 Apache as a Reverse Proxy. The looked up value here is a list of
6290 servers). Second, `int' with the built-in maps named `tolower' and
6291 `toupper' which can be used to map URL parts to a fixed case (this is an
6292 essential feature to fix the case of server names when doing mass
6293 virtual-hosting with the help of mod_rewrite instead of using
6294 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from

6297 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6298 This directive lets Apache adjust the URL in Location-headers on HTTP
6299 redirect responses sent by the remote server. This way the virtually
6300 mapped area is no longer left on redirects and thus by-passed which is
6301 especially essential when running Apache as a reverse proxy.

6392 source tree were updated to accurately reflect reality.
6395 *) Preserve the content encoding given by the AddEncoding directive
6396 when the client doesn't otherwise specify an encoding.
6397 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>]
6399 *) Sort out problems with canonical filename handling happening too late.
6400 [Dean Gaudet, Ben Laurie]
6402 Changes with Apache 1.3b4
6404 *) The module structure was modified to include a *dynamic_load_handle
6405 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
6406 has been bumped accordingly. [Paul Sutton]
6408 *) All BrowserMatch directives mentioned in
6409 htdocs/manual/known_client_problems.html are in the default
6410 configuration files. [Lars Eilebrecht]
6412 *) MiNT port update. [Jan Paul Schmidt]
6414 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
6415 equivalent, similarly for x-compress and compress. Apache
6416 now ignores a leading x- when comparing encodings. It also
6417 preserves the encoding the client requests (for example if
6418 it requests x-gzip, then Apache will respond with x-gzip
6419 in the Content-Encoding header).
6420 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
6422 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
6424 *) Added mod_so module to support dynamic loading of modules on Unix
6425 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
6426 instead of AddModule in Configuration to build shared modules
6427 [Sameer Parekh, Paul Sutton]
6429 *) Minor cleanups to r->finfo handling in some modules.
6432 *) Abstract read()/write() to ap_read()/ap_write().
6433 Makes it easier to add other types of IO code such as SFIO.
6436 *) API: Generalize default_port manipulations to make support of
6437 different protocols easier. [Ben Laurie, Randy Terbush]
6439 *) There are many cases where users do not want Apache to form
6440 self-referential urls using the "canonical" ServerName and Port.
6441 The new UseCanonicalName directive (default on), if set to off
6442 will cause Apache to use the client-supplied hostname and port.
6443 API: Part of this change required a change to the construct_url()
6444 prototype; and the addition of get_server_name() and
6446 [Michael Douglass <mikedoug@texas.net>, Dean Gaudet]
6447 PR#315, 459, 485, 1433
6449 *) Yet another rearrangement of the source tree.. now all the common
6450 header files are in the src/include directory. The -Imain -Iap
6451 references in Makefiles have been changed to the simpler -Iinclude
6452 instead. In addition to simplifying the build a little bit, this
6453 also makes it clear when a module is referencing something in a
6454 other than kosher manner (e.g., the proxy including mod_mime.h).
6455 Module-private header files (the proxy, mod_mime, the regex library,
6456 and mod_rewrite) have not been moved to src/include; nor have
6457 the OS-abstraction files. [Ken Coar]
6459 *) Fix a bug where r->hostname didn't have the :port stripped
6460 from it. [Dean Gaudet]
6462 *) Tweaked the headers_out table size, and the subprocess_env
6463 table size guess in rename_original_environment(). Added
6464 MAKE_TABLE_PROFILE which can help discover make_table()
6465 calls that use too small an initial guess, see alloc.c.
6468 *) Options and AllowOverride weren't properly merging in the main
6469 server setting inside vhosts (only an issue when you have no
6470 <Directory> or other section containing an Options that affects
6471 a request). Options +foo or -foo in the main_server wouldn't
6472 affect the main_server's lookup defaults. [Dean Gaudet]
6474 *) Variable 'cwd' was being used pointlessly before being set.
6477 *) r->allowed handling cleaned up in the standard modules.
6480 *) Some case-sensitivity issues cleaned up to be consistent with
6481 RFC2068. [Dean Gaudet]
6483 *) SIGURG doesn't exist everywhere.
6484 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6486 *) mod_unique_id was erroneously generating a second unique id when
6487 an internal redirect occured. Such redirects occur, for example,
6488 when processing a DirectoryIndex match. [Dean Gaudet]
6490 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6491 of the key and value. But in many cases this is not required
6492 because the key/value is a constant, or the value has been built
6493 by pstrcat() or other similar means. New routines table_addn,
6494 table_mergen, and table_setn have been added to the API, these
6495 routines do not pstrdup() their arguments. The core code and
6496 standard modules were changed to take advantage of these routines.
6497 The resulting server is up to 20% faster in some situations.
6499 Note that it is easy to get code subtly wrong if you pass a key/value
6500 which is in a pool other than the pool of the table. The only
6501 safe thing to do is to pass key/values which are in the pool of
6502 the table, or in one of the ancestors of the pool of the table.
6503 i.e. if the table is part of a subrequest, a value from the main
6504 request's pool is OK since the subrequest pool is a sub_pool of the
6505 main request's pool (and therefore has a lifespan at most as long as
6506 the main pool). There is debugging code which can detect improper
6507 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6508 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6510 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6511 which don't exist on disk more gracefully; handles vhosts properly.
6512 Update documentation to reflect the code -- if there's no
6513 MimeMagicFile directive then the module is not enabled.
6516 *) PORT: Some older *nix dialects cannot automatically start scripts
6517 which begin with a #! interpreter line (the shell starts the scripts
6518 appropriately on these platforms). Apache now supports starting of
6519 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6520 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6523 *) API: "typedef array_header table" removed from alloc.h, folks should
6524 have been writing to use table as if it were an opaque type, but even
6525 some standard modules got this wrong. By changing the definition
6526 to "typedef struct table table" module authors will receive compile
6527 time warnings that they're doing the wrong thing. This change
6528 facilitates future changes with more sophisticated table
6529 structures. Specifically, module authors should be using table_elts()
6530 to get access to an array_header * for the table. [Dean Gaudet]
6532 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6533 library routines. [Ken Coar, Rasmus Lerdorf]
6535 *) WIN32: mod_speling is now available on the Win32 platform.
6538 *) For clarity the following compile time definition was changed:
6540 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6542 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6543 and not be a general notice that the OS has mmap(). Now the
6544 HAVE_MMAP/SHMGET #defines strictly are informational that the
6545 OS has that method of shared memory; the type to use for
6546 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6547 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6548 determine if shared memory is available and allows Apache
6549 to determine the best method to use for the scoreboard.
6552 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6553 as do various earlier versions. It should be safe on all versions.
6554 Unixware 1.x appears to have the same SIGHUP bug as solaris does with
6555 the slack code. A few other cleanups for Unixware.
6556 [Tom Hughes <thh@cyberscience.com>] PR#1082, PR#1282, PR#1499, PR#1553
6558 *) PORT: A/UX can handle single-listen accepts without mutex
6559 locking, so we add SINGLE_LISTEN_UNSERIALIZED_ACCEPT. [Jim Jagielski]
6561 *) When die() happens we need to eat any request body if one exists.
6562 Otherwise we can't continue with a keepalive session. This shows up
6563 as a POST problem with MSIE 4.0, typically against pages which are
6564 authenticated. [Roy Fielding] PR#1399
6566 *) If you define SECURITY_HOLE_PASS_AUTHORIZATION then the Authorization
6567 header will be passed to CGIs. This is generally a security hole, so
6568 it's not a default. [Marc Slemko] PR#549
6570 *) Fix Y2K problem with date printing in suexec log.
6571 [Paul Eggert <eggert@twinsun.com>] PR#1343
6573 *) WIN32 deserves a pid file. [Ben Hyde]
6575 *) suexec errors now include the errno/description. [Marc Slemko] PR#1543
6577 *) PORT: OSF/1 now uses USE_FLOCK_SERIALIZED_ACCEPT to solve PR#467.
6578 The choice of flock vs. fcntl was made based on timings which showed that
6579 even on non-NFS, non-exported filesystems fcntl() was an order of
6580 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
6581 that single socket users will see no difference. [Dean Gaudet] PR#467
6583 *) "File does not exist" error message was erroneously including the
6584 errno. [Marc Slemko]
6586 *) Improve the warning message generated when a client drops the
6587 connection (hits stop button, etc.) during a send. [Roy Fielding]
6589 *) Defining GPROF will disable profiling in the parent and enable it
6590 in the children. If you're profiling under Linux this is pretty much
6591 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]
6593 *) htdigest and htpasswd needed slight tweaks to work on OS/2 and WIN32.
6596 *) The NeXT cc (which is gcc hacked up) doesn't appear to support some
6597 gcc functionality. Work around it.
6598 [Keith Severson <keith@sssd.navy.mil>] PR#1613
6600 *) Some linkers complain when .o files contain no functions.
6601 [Keith Severson <keith@sssd.navy.mil>] PR#1614
6603 *) Some const declarations in mod_imap.c that were added for debugging
6604 purposes caused some compilers heartburn without adding any
6605 significant value, so they've been removed. [Ken Coar]
6607 *) The src/main/*.h header files have had #ifndef wrappers added to
6608 insulate them against duplicate calls if they get included through
6609 multiple paths (e.g., in .c files as well as other .h files).
6612 *) The libap routines now have a header file for their prototypes,
6613 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
6615 *) mod_autoindex with a plaintext header file would emit the <PRE>
6616 start-tag before the HTML preamble, rather than after the preamble
6617 but before the header file contents. [John Van Essen <jve@gamers.org>]
6620 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
6621 only an issue on systems without a MAXDNAME define or where
6622 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
6624 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
6625 is used to read various types of files such as htaccess and
6626 htpasswd files. [Marc Slemko]
6628 *) SECURITY: Ensure that the buffer returned by ht_time is always
6629 properly null terminated. [Marc Slemko]
6631 *) The "Connection" header could be sent back with multiple "close"
6632 tokens. Not an error, but a waste.
6633 [Ronald.Tschalaer@psi.ch] PR#1683
6635 *) mod_rewrite's RewriteLog should behave like mod_log_config, it
6636 shouldn't force hostname lookups. [Dean Gaudet] PR#1684
6638 *) "basic" auth needs a case-insensitive comparison.
6639 [Ronald.Tschalaer@psi.ch] PR#1666
6641 *) For maximum portability, the environment passed to CGIs should
6642 only contain variables whose names match the regex
6643 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
6644 underscores over any character outside the regex. This
6645 affects HTTP_* variables, in a way that should be backward
6646 compatible for all the standard headers; and affects variables
6647 set with SetEnv/BrowserMatch and similar directives.
6650 *) mod_speling returned incorrect HREF's when an ambigous match
6651 was found. Noticed by <robinton@amtrash.comlink.de> (Soeren Ziehe)
6652 [robinton@amtrash.comlink.de (Soeren Ziehe), Martin Kraemer]
6654 *) PORT: Apache now compiles & runs on an EBCDIC mainframe
6655 (the Siemens BS2000/OSD family) in the POSIX subsystem
6658 *) PORT: Fix problem killing children when terminating. Allow ^C
6659 to shut down the server. [Brian Havard]
6661 *) pstrdup() is implicit in calls to table_* functions, so there's
6662 no need to do it before calling. Clean up a few cases.
6663 [Marc Slemko, Dean Gaudet]
6665 *) new -C and -c command line arguments
6667 -C "directive" : process directive before reading config files
6668 -c "directive" : process directive after reading config files
6670 httpd -C "PerlModule Apache::httpd_conf"
6671 [Doug MacEachern, Martin Kraemer]
6673 *) WIN32: Fix the execution of CGIs that are scripts and called
6674 with path info that does not have an '=' in.
6675 (eg. http://server/cgi-bin/printenv?foobar)
6676 [Marc Slemko] PR#1591
6678 *) WIN32: Fix a call to os_canonical_filename so it doesn't try to
6679 mess with fake filenames. This fixes proxy caching on
6682 *) SECURITY: General mod_include cleanup, including fixing several
6683 possible buffer overflows and a possible infinite loop.
6684 [Dean Gaudet, Marc Slemko]
6686 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6687 including fixing a possible buffer overflow. [Dean Gaudet]
6689 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
6690 (connections are not dropped). Code can handle graceful restarts
6691 (but there is as yet no way to signal this to Apache). Various
6692 other cleanups. [Paul Sutton]
6694 *) The aplog_error changes specific to 1.3 introduced a buffer
6695 overrun in the (now legacy) log_printf function. Fixed.
6698 *) mod_digest didn't properly deal with proxy authentication. It
6699 also lacked a case-insensitive comparision of the "Digest"
6700 token. [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1599
6702 *) A few cleanups in mod_status for efficiency. [Dean Gaudet]
6704 *) A few cleanups in mod_info to make it thread-safe, and remove an
6705 off-by-5 bug that could hammer \0 on the stack. [Dean Gaudet]
6707 *) no2slash() was O(n^2) in the length of the input. Make it O(n).
6710 *) API: migration from strncpy() to our "enhanced" version called
6711 ap_cpystrn() for performance and functionality reasons.
6712 Located in libap.a. [Jim Jagielski]
6714 *) table_set() and table_unset() did not deal correctly with
6715 multiple occurrences of the same key.
6716 [Stephen Scheck <sscheck@infonex.net>, Ben Laurie] PR#1604
6718 *) The AuthName must now be enclosed in quotes if it is to contain
6719 spaces. [Ken Coar] PR#1195
6721 *) API: new function: ap_escape_quotes(). [Ken Coar] PR#1195
6723 *) WIN32: Work around optimiser bug that killed ISAPI in release
6724 versions. [Ben Laurie] PR#1533
6726 *) PORT: Update the MPE port [Mark Bixby, Jim Jagielski]
6728 *) Interim (slow) fix for p->sub_pool critical sections in
6729 alloc.c (affects win32 only). [Ben Hyde]
6731 *) non-WIN32 was missing destroy_mutex definition. [Ben Hyde]
6733 *) send_fd_length() did not calculate total_bytes_sent properly.
6734 [Ben Reser <breser@regnow.com>] PR#1366
6736 *) The bputc() macro was not properly integrated with the chunking
6737 code; in many cases modules using bputc() could cause completely
6738 bogus chunked output. (Typically this will show up as problems
6739 with Internet Explorer 4.0 reading a page, but other browsers
6740 having no problem.) [Dean Gaudet]
6742 *) Create LARGE_WRITE_THRESHOLD define which determines how many
6743 bytes have to be supplied to bwrite() before it will consider
6744 doing a writev() to assemble multiple buffers in one system
6745 call. This is critical for modules such as mod_include,
6746 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
6747 strings in some cases. The result would be extra effort
6748 setting up writev(), and in many cases extra effort building
6749 chunks. The default is 31, it can be overriden at compile
6752 *) Move the gid switching code into the child so that log files
6753 and pid files are opened with the root gid.
6754 [Gregory A Lundberg <lundberg@vr.net>]
6756 *) WIN32: Check for binaries by looking for the executable header
6757 instead of counting control characters.
6758 [Jim Patterson <Jim.Patterson@Cognos.COM>] PR#1340
6760 *) ap_snprintf() moved from main/util_snprintf.c to ap/ap_snprintf.c
6761 so the functionality is available to applications other than the
6762 server itself (like the src/support tools). [Ken Coar]
6764 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
6765 the libap consolidation work. [Ken Coar]
6767 *) ap_snprintf() with a len of 0 behaved like sprintf(). This is not
6768 useful, and isn't what the standards require. Now it returns 0
6769 and writes nothing. [Dean Gaudet]
6771 *) When an error occurs in fcntl() locking suggest the user look up
6772 the docs for LockFile. [Dean Gaudet]
6774 *) Eliminate some dead code from writev_it_all().
6775 [Igor Tatarinov <tatarino@prairie.NoDak.edu>]
6777 *) mod_autoindex had an fread() without checking the result code.
6778 It also wouldn't handle "AddIconByType (TXT,/icons/text.gif text/*"
6779 (note the missing closing paren) properly. [Dean Gaudet]
6781 *) It appears the "257th byte" bug (see
6782 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
6783 at the 256th byte as well. Fixed. [Dean Gaudet]
6785 *) PORT: Fix mod_mime_magic under OS/2, no support for block devices.
6788 *) Fix memory corruption caused by allocating auth usernames in the
6789 wrong pool. [Dean Gaudet] PR#1500
6791 *) Fix an off-by-1, and an unterminated string error in
6792 mod_mime_magic. [Dean Gaudet]

6795 with type-maps. [Dean Gaudet]

6815 *) WIN32: Cure file leak in CGIs. [Peter Tillemans <pti@net4all.be>] PR#1523
6817 *) proxy_ftp: the directory listings generated by the proxy ftp module
6818 now have a title in which the path components are clickable and allow
6819 quick navigation to the clicked-on directory on the currently listed
6820 ftp server. This also fixes a bug where the ".." directory links would
6821 sometimes refer to the wrong directory. [Martin Kraemer]
6823 *) WIN32: Allocate the correct amount of memory for the scoreboard.
6826 *) WIN32: Only lowercase the part of the path that is real. [Ben Laurie]
6829 *) Fix problems with timeouts in inetd mode and -X mode. [Dean Gaudet]
6831 *) Fix the spurious "(0)unknown error: mmap_handler: mmap failed"

6834 Changes with Apache 1.3b3
6836 *) WIN32: Work around brain-damaged spawn calls that can't deal
6837 with spaces and slashes. [Ben Laurie]
6839 *) WIN32: Fix the code so CGIs can use socket calls on Windows.
6840 The problem was that certain undocumented environment variables
6841 needed for sockets to work under Win32 were not being passed.

6844 *) Add a "-V" command line flag to the httpd binary. This
6845 flag shows some of the defines that Apache was compiled with.
6846 It is useful for debugging purposes. [Martin Kraemer]

6858 *) WIN32: Some Win32 systems terminated all responses after 16 kB.
6859 This turns out to be a bug in Winsock - select() doesn't always
6860 return the correct status. [Ben Laurie]
6862 *) Directives owned by http_core can now use the new check_cmd_context()
6863 routine to ensure that they're not being used within a container
6864 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
6866 *) PORT: Recent changes made it necessary to add explicit prototype
6867 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
6869 *) It was necessary to distinguish between resources which are
6870 allocated in the parent, for cleanup in the parent, and resources
6871 which are allocated in each child, for cleanup in each child.
6872 A new pool was created which is passed to the module child_init
6873 and child_exit functions; modules are free to register per-child
6874 cleanups there. This fixes a bug with reliable piped logs.
6877 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
6878 unless it was also doing FancyIndexes, but it displayed the
6879 HeaderName file at the top under all circumstances. It now shows
6880 the ReadmeName file for simple indices, too, as it should.
6883 *) http_core was mmap()ing even in cases where it wasn't going to
6884 read the file. [Ben Hyde <bhyde@gensym.com>]
6886 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
6887 Now the rewriting engine (the heart of mod_rewrite) is organized more
6888 straight-forward, first time well documented and reduced to the really
6889 essential parts. All redundant cases were stripped off and processing now
6890 is the same for both per-server and per-directory context with only a
6891 minimum difference (the prefix stripping in per-dir context). As a
6892 side-effect some subtle restrictions and two recently discovered problems
6893 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
6894 context and restrictions on the substitution URL on redirects.
6895 Additionally some minor source cleanups were done.

7050 Changes with Apache 1.3b2 (there is no 1.3b1)
7052 *) TestCompile was not passing $LIBS [Dean Gaudet]
7054 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7057 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7058 rudimentary memory debugger which can be used on live servers with
7059 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7060 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7061 and free() for each object. This is far more expensive and should
7062 only be used for testing with tools such as Electric Fence and
7063 Purify. See main/alloc.c for more details. [Dean Gaudet]
7065 *) Configure uses a sh trap and didn't set its exitcode properly.
7066 [Dean Gaudet] PR#1159
7068 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7069 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7070 From a given ip:port, regardless what the Host: header is, you can
7071 only reach the vhosts defined on that ip:port. The precedence of
7072 vhosts was reversed to match other precedences in the config --
7073 the earlier vhosts override the later vhosts. All vhost matching was
7074 moved into http_vhost.[ch]. [Dean Gaudet]
7076 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7077 be used for whatever reason is appropriate (i.e. format() warnings
7078 for printf style functions). Both are enabled only with
7079 gcc >= 2.7.x (so that we have fewer support issues with older
7080 versions). [Dean Gaudet]
7082 *) Fix support for Proxy Authentication (we were testing the response
7083 status too early). [Marc Slemko]
7085 *) CoreDumpDirectory directive directs where the core file is
7086 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7087 received. [Marc Slemko, Dean Gaudet]

7090 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7092 *) When booting, apache will now detach itself from stdin, stdout,
7093 and stderr. stderr will not be detached until after the config
7094 files have been read so you will be able to see initial error
7095 messages. After that all errors are logged in the error_log.
7096 This makes it more convenient to start apache via rsh, ssh,
7097 or crontabs. [Dean Gaudet] PR#523
7099 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7100 Also removed the auto-generated link to www.apache.org that was the
7101 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7103 *) send_fb would not detect aborted connections in some situations.
7106 *) mod_include would use uninitialized data when parsing certain
7107 expressions involving && and ||. [Brian Slesinsky] PR#1139
7109 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7111 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7113 *) mod_autoindex improperly counted &escapes; as more than one
7114 character in the description. It also improperly truncated
7115 descriptions that were exactly the maximum length.
7118 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7119 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7122 *) mod_include now uses symbolic names to check for request success
7123 and return HTTP errors, and correctly handles all types of
7124 redirections (previously it only did temporary redirect correctly).
7125 [Ken Coar, Roy Fielding]
7127 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7128 r->filename. Since those two are meant to be in sync with each other
7129 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]

7138 reporting a select error over and over.
7139 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7141 *) Fixed error in proxy_util.c when looping through multiple host IP
7142 addresses. [Lars Eilebrecht] PR#974
7144 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7145 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7146 bytes before writing, but it will never split a log entry across a
7147 buffer boundary. [Dean Gaudet]
7149 *) API: the short_score record has been split into two pieces, one which
7150 the parent writes on, and one which the child writes on. As part of
7151 this change the get_scoreboard_info() function was removed, and
7152 scoreboard_image was exported. This change fixes a race condition
7153 in file based scoreboard systems, and speeds up changes involving the
7154 scoreboard in earlier 1.3 development. [Dean Gaudet]
7156 *) API: New register_other_child() API (see http_main.h) which allows
7157 modules to register children with the parent for maintenance. It
7158 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7160 *) API: New piped_log API (see http_log.h) which implements piped logs,
7161 and will use register_other_child to implement reliable piped logs
7162 when it is available. The reliable piped logs part can be disabled
7163 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7164 logs is only available on Unix. [Dean Gaudet]
7166 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7167 meets_conditions(). This allows conditional HTTP selection to be
7168 handled separately from the storing of the header fields, and provides
7169 the ability for CGIs to set their own ETags for conditional checking.
7170 [Ken Coar, Roy Fielding] PR#895
7172 *) Changes to mod_log_config to allow naming of format strings.
7173 Format nicknames are defined with "LogFormat fmt nickname", and can
7174 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7177 *) New module, "mod_speling", which can help find files even when
7178 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7180 *) API: New function child_terminate() triggers the child process to
7181 exit, while allowing the child finish what it needs to for the
7182 current request first.
7183 [Doug MacEachern, Alexei Kosut]
7185 *) Windows now defaults to using full status reports with mod_status.
7186 [Alexei Kosut] PR #1094
7188 *) *Really* disable all mod_rewrite operations if the engine is off.
7189 Some things (like RewriteMaps) were checked/performed even if they
7190 weren't supposed to be. [Ken Coar] PR #991
7192 *) Implement a new timer scheme which eliminates the need to call alarm() all
7193 the time. Instead a counter in the scoreboard for each child is used to
7194 show when the child has made forward progress. The parent samples this
7195 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7196 progress has been made in the timeout period. This reduces the static
7197 request best-case syscall count to 22 from 29. This scheme is only
7198 used by systems with memory-based scoreboards. [Dean Gaudet]
7200 *) The proxy now properly handles CONNECT requests which are sent
7201 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7203 *) A script called apachectl has been added to the support
7204 directory. This script allows you to do things such as
7205 "apachectl start" and "apachectl restart" from the command
7208 *) Modules and core routines are now put into libraries, which
7209 simplifies the link line tremendously (among other advantages).
7212 *) Some of the MD5 names defined in Apache have been renamed to have
7213 an `ap_' prefix to avoid conflicts with routines supplied by
7214 external libraries. [Ken Coar]
7216 *) Removal of mod_auth_msql.c from the distribution. There are many
7217 other options for databases today. Rather than offer one option,
7218 offer none at this time. mod_auth_msql and other SQL database
7219 authentication modules can be found at the Apache Module Registry.
7220 http://modules.apache.org/ It would be nice to offer a generic
7221 mod_auth_sql option in the near future.
7223 *) PORT: BeOS support added [Alexei Kosut]
7225 *) Configure no longer accepts the -make option, since it creates
7226 Makefile on the fly based on Makefile.tmpl and Configuration.
7228 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7229 of forcibly killing off all its processes and exiting without
7230 cleaning up. [Alexei Kosut]
7232 *) API: A new field in the request_rec, r->mtime, has been added to
7233 avoid gratuitous parsing of date strings. It is intended to hold
7234 the last-modified date of the resource (if applicable). An
7235 update_mtime() routine has also been added to advance it if
7236 appropriate. [Roy Fielding, Ken Coar]
7238 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7239 deny access to the directory with a HTTP_FORBIDDEN. The previous
7240 behavior was to ignore the htaccess file if it could not be read.
7241 This change may make some setups with unreadable htaccess files
7242 stop working. [Marc Slemko] PR#817
7244 *) Add aplog_error() providing a mechanism to define levels of
7245 verbosity to the server error logging. This addition also provides
7246 the ability to log errors using syslogd. Error logging is configurable
7247 on a per-server basis using the LogLevel directive. Conversion
7248 of log_*() in progress. [Randy Terbush]
7250 *) Further enhance aplog_error() to not log filename, line number, and
7251 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7253 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7254 converted to long ones. Backslashes are converted to forward
7255 slashes. Case is converted to lower. Parts of URLs that do not
7256 correspond to files are left completely alone. [Ben Laurie]
7258 *) PORT: 2 new OSs added to the list of ports:
7259 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7260 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7262 *) Add the server version (SERVER_VERSION macro) to the "server
7263 configured and running" entry in the error_log. Also build an
7264 object file at link-time that contains the current time
7265 (SERVER_BUILT global const char[]), and include that in the
7268 *) Set r->headers_out when sending responses from the proxy.
7269 This fixes things such as the logging of headers sent from
7270 the proxy. [Marc Slemko] PR#659
7272 *) support/httpd_monitor is no longer distributed because the
7273 scoreboard should not be file based if at all possible. Use
7274 mod_status to see current server snapshot.
7276 *) (set_file_slot): New function, allowing auth directives to be
7277 independent of the server root, so the server documents can be
7278 moved to a different directory or machine more easily.
7279 [David J. MacKenzie]
7281 *) If no TransferLog is given explicitly, decline
7282 to log. This supports coexistence with other logging modules,
7283 such as the custom one that UUNET uses. [David J. MacKenzie]
7285 *) Check for titles in server-parsed HTML files.
7286 Ignore leading newlines and returns in titles. The old behavior
7287 of replacing a newline after <title> with a space causes the
7288 title to be misaligned in the listing. [David J. MacKenzie]
7290 *) Change mod_cern_meta to be configurable on a per-directory basis.
7291 [David J. MacKenzie]
7293 *) Add 'Include' directive to allow inclusion of configuration
7294 files within configuration files. [Randy Terbush]
7296 *) Proxy errors on connect() are logged to the error_log (nothing
7297 new); now they include the IP address and port that failed
7298 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7300 *) Various architectures now define USE_MMAP_FILES which causes
7301 the server to use mmap() for static files. There are two
7302 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7303 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7304 number of bytes written in one cycle from a single mmap()d object,
7305 default 32768). [Dean Gaudet]
7307 *) API: Added post_read_request API phase which is run right after reading
7308 the request from a client, or right after an internal redirect. It is
7309 useful for modules setting environment variables that depend only on
7310 the headers/contents of the request. It does not run during subrequests
7311 because subrequests inherit pretty much everything from the main
7312 request. [Dean Gaudet]
7314 *) Added mod_unique_id which is used to generate a unique identifier for
7315 each hit, available in the environment variable UNIQUE_ID.
7318 *) init_modules is now called after the error logs have been opened. This
7319 allows modules to emit information messages into the error logs.
7322 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7323 information for case where proxy module is not available. [Marc Slemko]
7325 *) PORT: Apache has need for mutexes to serialize its children around
7326 accept. In prior versions either fcntl file locking or flock file
7327 locking were used. The method is chosen by the definition of
7328 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7329 and FLOCK for flock(). New options have been added:
7330 - SYSVSEM to use System V style semaphores
7331 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7332 - USLOCK to use IRIX uslock
7333 Based on timing various techniques, the following changes were made
7335 - Linux 2.x uses flock instead of fcntl
7336 - Solaris 2.x uses pthreads
7337 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7338 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7339 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7340 Martijn Koster <m.koster@pobox.com>]
7342 *) PORT: The semantics of accept/select make it very desirable to use
7343 mutexes to serialize accept when multiple Listens are in use. But
7344 in the case where only a single socket is open it is sometimes
7345 redundant to serialize accept(). Not all unixes do a good job with
7346 potentially dozens of children blocked on accept() on the same
7347 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7348 the server will avoid serialization when listening on only one socket,
7349 and use serialization when listening on multiple sockets.
7350 [Dean Gaudet] PR#467
7352 *) Configure changes: TestLib replaced by TestCompile, which has
7353 some additional capability (such as doing a sanity check of
7354 the compiler and flags selected); the version of Solaris is now
7355 available via the #define value of SOLARIS2; IRIX n32bit libs
7356 now supported and selectable by new Configuration Rule: IRIXN32;
7357 We no longer default to -O2 optimization. [Jim Jagielski]
7359 *) Updated Configure: Configuration now uses AddModule to specify
7360 module source or binary file location, relative to src directory.
7361 Modules can be dropped into modules/extra, or in their own
7362 directory, and modules can come with a Makefile or Configure can
7363 create one. Modules can add compiler or library information to
7364 generated Makefiles. [Paul Sutton]
7366 *) Source core re-organisation: distributed modules are now in
7367 modules/standard. All other source code is in main. OS-specific
7368 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7370 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7373 *) Fix another long-standing bug in sub_req_lookup_file where it would
7374 happily skip past access checks on subdirectories looked up with
7375 relative paths. (It's used by mod_dir, mod_negotiation,
7376 and mod_include.) [Dean Gaudet]
7378 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7379 N is the number of <Directory> sections, and M is the number of
7380 components in the filename of an object.
7382 To achieve this optimization the following config changes were made:
7383 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7384 <Files>s, and <Location>s now treat a slash as a special
7385 character. For example "/home/*/public_html" previously would
7386 match "/home/a/andrew/public_html", now it only matches things
7387 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7388 - It's possible now to use [] wildcarding in <Directory>, <Files>
7390 - Regex <Directory>s are applied after all non-regex <Directory>s.
7394 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7395 and corrupted paths. [Dean Gaudet]
7397 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7398 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7399 be accessed now via backreferences $1..$9 in RewriteConds test-against
7400 strings in addition to RewriteRules subst string. Second the grouped
7401 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7402 via backreferences %1..%9 both in following RewriteCond test-against
7403 strings and RewriteRules subst string. This provides maximum flexibility
7404 through the use of backreferences.
7405 Additionally the rewriting engine was cleaned up by putting common
7406 code to the new expand_backrefs_inbuffer() function.
7407 [Ralf S. Engelschall]
7409 *) When merging the main server's <Directory> and <Location> sections into
7410 a vhost, put the main server's first and the vhost's second. Otherwise
7411 the vhost can't override the main server. [Dean Gaudet] PR#717
7413 *) The <Directory> code would merge and re-merge the same section after
7414 a match was found, possibly causing problems with some modules.
7417 *) ip-based vhosts are stored and queried using a hashing function, which
7418 has been shown to improve performance on servers with many ip-vhosts.
7419 Some other changes had to be made to accommodate this:
7420 - the * address for vhosts now behaves like _default_
7421 - the matching process now is:
7422 - match an ip-vhost directly via hash (possibly matches main
7424 - if that fails, just pretend it matched the main server
7425 - if so far only the main server has been matched, perform
7426 name-based lookups (ServerName, ServerAlias, ServerPath)
7427 *only on name-based vhosts*
7428 - if they fail, look for _default_ vhosts
7429 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7431 *) dbmmanage overhaul:
7432 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7433 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7434 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7435 - provide better seed for rand
7436 - prompt for password as per getpass(3) (turn off echo, read from
7438 - use "newstyle" crypt based on $Config{osname} ($^O)
7439 - will not add a user if already in database, use new `update' command
7441 - added `check' command to check a users' password
7442 - added `import' command to convert existing password text-files or
7443 dbm files exported with `view'
7444 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7447 *) Added psocket() which is a pool form of socket(), various places within
7448 the proxy weren't properly blocking alarms while registering the cleanup
7449 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7450 was a bug where the client socket was being close()d twice due a still
7451 registered cleanup. [Dean Gaudet]
7453 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7456 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7457 [Jason Venner <jason@idiom.com>] PR#667
7459 *) Enable ``=""'' for RewriteCond directives to match against
7460 the empty string. This is the preferred way instead of ``^$''.
7461 [Ralf S. Engelschall]
7463 *) Fixed an infinite loop in mod_imap for references above the server root
7464 [Dean Gaudet] PR#748
7466 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7467 SendBufferSize, so that the TCP window can be set appropriately
7468 for LFNs. [Phillip A. Prindeville]
7470 *) mod_browser has been replaced by the more general mod_setenvif
7471 (courtesy of Paul Sutton). BrowserMatch* directives are still
7472 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7473 UnSetEnvIfZero directives. [Ken Coar]
7475 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7476 order for remote_host to be set (for logging, or for the env var
7477 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7480 *) mod_access overhaul:
7481 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7482 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7483 - Critical path was sped up by pre-computing a few things at config time.
7484 - The undocumented syntax "allow user-agents" was removed,
7485 the replacement is "allow from env=foobar" combined with mod_browser.
7486 - When used with hostnames it now forces a double-reverse lookup
7487 no matter what the directory settings are. This double-reverse
7488 doesn't affect any of the other routines that use the remote
7489 hostname. In particular it's still passed to CGIs and the log
7490 without the double-reverse check. Related PR#860.
7493 *) When a large bwrite() occurs (larger than the internal buffer size),
7494 while there is already something in the buffer, apache will combine
7495 the large write and the buffer into a single writev(). (This is
7496 in anticipation of using mmap() for reading files.)
7499 *) In obscure cases where a partial socket write occurred while chunking,
7500 Apache would omit the chunk header/footer on the next block. Cleaned
7501 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7502 a bug where a long pause in DNS lookups could cause the last packet
7503 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7505 *) API: Added child_exit function to module structure. This is called
7506 once per "heavy-weight process" just before a server child exit()'s
7507 e.g. when max_requests_per_child is reached, etc.
7508 [Doug MacEachern, Dean Gaudet]
7510 *) mod_include cleanup showed that handle_else was being used to handle
7511 endif. It didn't cause problems, but it was cleaned up too.
7514 *) mod_cern_meta would attempt to find meta files for the directory itself
7515 in some cases, but not in others. It now avoids it in all cases.
7518 *) mod_mime_magic would core dump if there was a decompression error.
7519 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7521 *) PORT: some variants of DGUX require -lsocket -lnsl
7522 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7524 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7525 by the various fields (name, size, et cetera), either in ascending
7526 or descending order. Just click on the column header. [Ken Coar]
7528 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7529 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7530 the relatively safe direction. [Dean Gaudet] PR#344
7532 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7533 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7535 *) child_main avoids an unneeded call to select() when there is only one
7536 listening socket. [Dean Gaudet]
7538 *) In the event that the server is starved for idle servers it will
7539 spawn 1, then 2, then 4, ..., then 32 servers each second,
7540 doubling each second. It'll also give a warning in the errorlog
7541 since the most common reason for this is a poor StartServers
7542 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7543 the maximum. [Dean Gaudet]
7545 *) Apache now provides an effectively unbuffered connection for
7546 CGI scripts. This means that data will be sent to the client
7547 as soon as the CGI pauses or stops output; previously, Apache would
7548 buffer the output up to a fixed buffer size before sending, which
7549 could result in the user viewing an empty page until the CGI finished
7550 or output a complete buffer. It is no longer necessary to use an
7551 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7552 in a language that by default does buffering (e.g. perl) this
7553 shouldn't have a detrimental effect on performance.
7555 "nph-" CGIs, which formerly provided a direct socket to the client
7556 without any server post-processing, were not fully compatible with
7557 HTTP/1.1 or SSL support. As such they would have had to implement
7558 the transport details, such as encryption or chunking, in order
7559 to work properly in certain situations. Now, the only difference
7560 between nph and non-nph scripts is "non-parsed headers".
7561 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7563 *) If a BUFF is switched from buffered to unbuffered reading the first
7564 bread() will return whatever remained in the buffer prior to the
7565 switch. [Dean Gaudet]
7567 Changes with Apache 1.3a1
7569 *) Added another Configure helper script: TestLib. It determines
7570 if a specified library exists. [Jim Jagielski]
7572 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7573 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7576 *) PORT: Some architectures use size_t for various lengths in network
7577 functions such as accept(), and getsockname(). The definition
7578 NET_SIZE_T is used to control this. [Dean Gaudet]
7580 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7581 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7582 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7584 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7585 [Igor N Kovalenko <infoh@mail.wplus.net>]
7587 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7588 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7589 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7590 [Dean Gaudet] related PR#875
7592 *) API: Correct child_init() slot declaration from int to void, to
7593 match the init() declaration. Update mod_example to use the new
7596 *) added transport handle slot (t_handle) to the BUFF structure
7599 *) get_client_block() returns wrong length if policy is
7600 REQUEST_CHUNKED_DECHUNK.
7601 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815

7608 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
7610 *) AddModuleInfo directive for mod_info which allows you to annotate
7611 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7613 *) Added NoProxy directive to avoid using ProxyRemote for selected
7614 addresses. Added ProxyDomain directive to cause unqualified
7615 names to be qualified by redirection.
7616 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7618 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7619 header to the remote host in the proxy. [Sameer Parekh and
7622 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7623 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7624 URLs, fixed rewritelog(), fixed forced response code handling on
7625 redirects from within .htaccess files, disabled pipe locking under
7626 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7627 no substitution, bugfixed situations where HostnameLookups is off, made
7628 mod_rewrite more thread-safe for NT port and fixed problem when creating
7629 an empty query string via "xxx?".
7630 This update also removes the copyright of Ralf S. Engelschall,
7631 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7632 exclusively copyrighted by the Apache Group now. This happened because
7633 the author now has gifted mod_rewrite exclusively to the Apache Group and
7634 no longer maintains an external version.
7635 [Ralf S. Engelschall]
7637 *) API: Added child_init function to module structure. This is called
7638 once per "heavy-weight process" before any requests are handled.
7639 See http_config.h for more details. [Dean Gaudet]
7641 *) Anonymous_LogEmail was logging on each subrequest.
7642 [Dean Gaudet] PR#421, 868
7644 *) API: Added is_initial_req() which tests if the request being
7645 processed is the initial request, or a subrequest.
7648 *) Extended SSI (mod_include) now handles additional relops for
7649 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7651 *) Configure fixed to correctly propagate user-selected options and
7652 settings (such as CC and OPTIM) to Makefiles other than
7653 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7655 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7656 directory indices to start with the contents of the HeaderName file
7657 if there is one. If there isn't one, the behaviour is unchanged.
7658 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7660 *) WIN32: Modules can now be dynamically loaded DLLs using the
7661 LoadModule/LoadFile directives. Note that module DLLs must be
7662 compiled with the multithreaded DLL version of the runtime library.
7663 [Alexei Kosut and Ben Laurie]
7665 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7666 This allows the admin to completely remove automatic indexing
7667 from the server, while still supporting the basic functions of
7668 trailing-slash redirects and DirectoryIndex files. Note that if
7669 you're carrying over an old Configuration file and you use directory
7670 indexing then you'll want to add:
7672 Module autoindex_module mod_autoindex.o
7674 before mod_dir in your Configuration. [Dean Gaudet]
7676 *) popendir/pclosedir created to properly protect directory scanning.
7677 [Dean Gaudet] PR#525
7679 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7680 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7681 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7684 *) The AccessFileName directive can now take more than one filename.
7685 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7687 *) The new mod_mime_magic can be used to "magically" determine the type
7688 of a file if the extension is unknown. Based on the unix file(1)
7689 command. [Ian Kluft <ikluft@cisco.com>]
7691 *) We now determine and display the time spent processing a
7692 request if desired. [Jim Jagielski]
7694 *) mod_status: PID field of "dead" child slots no longer displays
7695 main httpd process's PID. [Jim Jagielski]
7697 *) Makefile.nt added - to build all the bits from the command line:
7698 nmake -f Makefile.nt
7699 Doesn't yet work properly. [Ben Laurie]
7701 *) Default text of 404 error is now "Not Found" rather than the
7702 potentially misleading "File Not Found". [Ken Coar]
7704 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7705 for the net if we require people that actually need this data to
7706 enable it. [Linus Torvalds]
7708 *) directory_walk() is an expensive function, keep a little more state to
7709 avoid needless string counting. Add two new functions make_dirstr_parent
7710 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7711 The new functions are a little less general than make_dirstr, but
7712 work more efficiently (less memory, less string counting).
7715 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7716 to LDFLAGS) to avoid complications with lex rules in make files.
7717 [Dean Gaudet] PR#372
7719 *) run_method optimized to avoid needless scanning over NULLs in the
7720 module list. [Dean Gaudet]
7722 *) Revamp of (unix) scoreboard management code such that it avoids
7723 unnecessary traversals of the scoreboard on each hit. This is
7724 particularly important for high volume sites with a large
7725 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7726 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7727 httpd.h. [Dean Gaudet]
7729 *) In configurations using multiple Listen statements it was possible for
7730 busy sockets to starve other sockets of service. [Dean Gaudet]
7732 *) Added hook so standalone_main can be replaced at compile time
7733 (define STANDALONE_MAIN)
7736 *) Lowest-level read/write functions in buff.c will be replaced with
7737 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7738 compile time. The default sfio discipline will behave as apache
7739 would without sfio compiled in.
7742 *) Enhance UserDir directive (mod_userdir) to accept a list of
7743 usernames for the 'disable' keyword, and add 'enable user...' to
7744 selectively *en*able userdirs if they're globally disabled.
7747 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7748 will work with Netscape dbm files. (dbmmanage will probably not
7749 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7751 *) Add a ListenBacklog directive to control the backlog parameter
7752 passed to listen(). Also change the default to 511 from 512.
7755 *) API: A new handler response DONE which informs apache that the
7756 request has been handled and it can finish off quickly, similar to
7757 how it handles errors. [Rob Hartill]
7759 *) Turn off chunked encoding after sending terminating chunk/footer
7760 so that we can't do it twice by accident. [Roy Fielding]
7762 *) mod_expire also issues Cache-Control: max-age headers.
7765 *) API: Added kill_only_once option for free_proc_chain so that it won't
7766 aggressively try to kill off specific children. For fastcgi.
7767 [Stanley Gambarin <gambarin@OpenMarket.com>]
7769 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7771 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7772 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7773 attributes in the FancyIndexing IMG tags. [Ken Coar]
7775 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7777 *) PORT: Added Windows NT support
7778 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7780 Changes with Apache 1.2.6
7782 *) mod_include when using XBitHack Full would send ETags in addition to
7783 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7784 [Dean Gaudet] PR#1133
7786 *) SECURITY: When a client connects to a particular port/addr, and
7787 gives a Host: header ensure that the virtual host requested can
7788 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7790 *) Support virtual hosts with wildcard port and/or multiple ports
7791 properly. [Ed Korthof <ed@organic.com>]
7793 *) Fixed some case-sensitivity issues according to RFC2068.
7796 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7797 and mod_include.c. [Dean Gaudet]
7799 *) Variable 'cwd' was being used pointlessly before being set.
7802 *) SIGURG doesn't exist on all platforms.
7803 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7805 *) When an error occurs during a POST, or other operation with a
7806 request body, the body has to be read from the net before allowing
7807 a keepalive session to continue. [Roy Fielding] PR#1399
7809 *) When an error occurs in fcntl() locking suggest the user look up
7810 the docs for LockFile. [Dean Gaudet]
7812 *) table_set() and table_unset() did not deal correctly with
7813 multiple occurrences of the same key. [Stephen Scheck
7814 <sscheck@infonex.net>, Ben Laurie] PR#1604
7816 *) send_fd_length() did not calculate total_bytes_sent properly in error
7817 cases. [Ben Reser <breser@regnow.com>] PR#1366
7819 *) r->connection->user was allocated in the wrong pool causing corruption
7820 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7822 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7823 Also removed the auto-generated link to www.apache.org that was the
7824 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7826 *) Multiple "close" tokens may have been set in the "Connection"
7827 header, not an error, but a waste.
7828 [Ronald.Tschalaer@psi.ch] PR#1683
7830 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7831 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7833 *) It appears the "257th byte" bug (see
7834 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7835 at the 256th byte as well. Fixed. [Dean Gaudet]
7837 *) mod_rewrite would not handle %3f properly in some situations.
7840 *) Apache could generate improperly chunked HTTP/1.1 responses when
7841 the bputc() or rputc() functions were used by modules (such as
7842 mod_include). [Dean Gaudet]
7844 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7845 some ports. [Ralf Engelschall]
7847 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7849 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7851 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7853 Changes with Apache 1.2.5
7855 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7856 only an issue on systems without a MAXDNAME define or where
7857 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7859 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7862 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7863 directory listings. [Marc Slemko]
7865 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7868 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7869 is used to read various types of files such as htaccess and
7870 htpasswd files. [Marc Slemko]
7872 *) SECURITY: Ensure that the buffer returned by ht_time is always
7873 properly null terminated. [Marc Slemko]
7875 *) SECURITY: General mod_include cleanup, including fixing several
7876 possible buffer overflows and a possible infinite loop. This cleanup
7877 was done against 1.3 code and then backported to 1.2, the result
7878 is a large difference (due to indentation cleanup in 1.3 code).
7879 Users interested in seeing a smaller set of relevant differences
7880 should consider comparing against src/modules/standard/mod_include.c
7881 from the 1.3b3 release. Non-indentation changes to mod_include
7882 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7884 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7885 including fixing a possible buffer overflow. This cleanup also
7886 was done with 1.3 code as a basis, see the the previous note
7887 about mod_include. [Dean Gaudet]
7889 *) SECURITY: If a htaccess file can not be read due to bad
7890 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7891 The previous behavior was to ignore the htaccess file if it could not
7892 be read. This change may make some setups with unreadable
7893 htaccess files stop working. PR#817 [Marc Slemko]
7895 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7896 Make it O(n). This inefficiency could be used to mount a denial
7897 of service attack against the Apache server. Thanks to

7921 [Rick Franchuk <rickf@transpect.net>] PR#1107
7923 Changes with Apache 1.2.4
7925 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7926 always making requests with the full-URI instead of just the URI path.
7927 [Marc Slemko, Roy Fielding]
7929 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7930 on this platform. [Marc Slemko]
7932 Changes with Apache 1.2.3
7934 *) The request to a remote proxy was mangled if it was generated as the

7939 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7940 information for case where proxy module is not available. [Marc Slemko]
7942 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7943 do for errors and cached responses. [Roy Fielding]
7945 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7947 Changes with Apache 1.2.2 [not released]
7949 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7950 happily skip past access checks on subdirectories looked up with relative
7951 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7954 *) Add lockfile name to error message printed out when
7955 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7958 *) Enhanced the chunking and error handling inside the buffer functions.
7959 [Dean Gaudet, Roy Fielding]

7962 a vhost, put the main server's first and the vhost's second. Otherwise
7963 the vhost can't override the main server. [Dean Gaudet] PR#717
7965 *) The <Directory> code would merge and re-merge the same section after

7976 *) Last official synchronization of mod_rewrite with author version (because
7977 mod_rewrite is now directly developed by the author at the Apache Group):
7978 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7979 minus WIN32/NT stuff, but plus copyright removement.
7981 - workaround for detecting infinite rewriting loops
7982 - fixed setting of env vars when "-" is used as subst string
7983 - fixed forced response code on redirects (PR#777)
7984 - fixed cases where r->args is ""
7985 - kludge to disable locking on pipes under braindead SunOS
7986 - fix for rewritelog in cases where remote hostname is unknown
7987 - fixed totally damaged request_rec walk-back loop
7988 o remove static from local data and add static to global ones.
7989 o replaced ugly proxy finding stuff by simple
7990 find_linked_module("mod_proxy") call.
7991 o added missing negation char on rewritelog()
7992 o fixed a few comment typos

7998 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7999 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
8000 "downgrade-1.0" which causes Apache to pretend it received a 1.0.

8021 [Dean Gaudet] PR#832
8023 *) API: In HTTP/1.1, whether or not a request message contains a body
8024 is independent of the request method and based solely on the presence
8025 of a Content-Length or Transfer-Encoding. Therefore, our default
8026 handlers need to be prepared to read a body even if they don't know
8027 what to do with it; otherwise, the body would be mistaken for the
8028 next request on a persistent connection. discard_request_body()
8029 has been added to take care of that. [Roy Fielding] PR#378
8031 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
8032 release version number, such that it always increases along the
8033 same lines as our source code branching. [Roy Fielding]
8035 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
8037 Changes with Apache 1.2.1
8039 *) SECURITY: Don't serve file system objects unless they are plain files,
8040 symlinks, or directories. This prevents local users from using pipes
8041 or named sockets to invoke programs for an extremely crude form of

8045 could contain "../" allowing a local user to "publish" any file on
8046 the system. No slashes are allowed now. [Dean Gaudet]
8048 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8049 (headers, readmes, titles), mod_negotiation (type maps), or
8050 mod_cern_meta (meta files). [Dean Gaudet]
8052 *) SECURITY: Apache will refuse to run as "User root" unless
8053 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8055 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8056 if it contained a .htaccess disallowing symlinks. This is contrary
8057 to the rule that symlink permissions are tested with the symlink
8058 options of the parent directory. [Dean Gaudet] PR#353
8060 *) CONFIG: The LockFile directive can be used to place the serializing
8061 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8062 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8065 *) Request processing now retains state of whether or not the request
8066 body has been read, so that internal redirects and subrequests will
8067 not try to read it twice (and block). [Roy Fielding]
8069 *) Add a placeholder in modules/Makefile to avoid errors with certain
8070 makes. [Marc Slemko]
8072 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
8073 [Dean Gaudet] PR#644
8075 *) mod_include was not properly changing the current directory.
8076 [Marc Slemko] PR#742
8078 *) Attempt to work around problems with third party libraries that do not
8079 handle high numbered descriptors (examples include bind, and
8080 solaris libc). On all systems apache attempts to keep all permanent
8081 descriptors above 15 (called the low slack line). Solaris users
8082 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8083 which keeps all non-FILE * descriptors above 255. On all systems
8084 this should make supporting large numbers of vhosts with many open
8085 log files more feasible. If this causes trouble please report it,
8086 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8087 [Dean Gaudet] various PRs
8089 *) Related to the last entry, network sockets are now opened before
8090 log files are opened. The only known case where this can cause
8091 problems is under Solaris with many virtualhosts and many Listen
8092 directives. But using -DHIGH_SLACK_LINE=256 described above will
8093 work around this problem. [Dean Gaudet]
8095 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8098 *) Improved unix error response logging. [Marc Slemko]

8101 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8102 when a URL http://... was used in conjunction with a special

8148 reading from one buffer and writing to another, at least until it has
8149 a custom timeout handler. [Roy Fielding and Petr Lampa]

8159 *) Virtual hosts with the same ServerName, but on different ports, were
8160 not being selected properly. [Ed Korthof]

8164 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8165 [Chuck Murcko] PR#614
8167 *) If multiple requests on a single connection are used to retrieve
8168 data from different virtual hosts, the virtual host list would be

8184 *) If a soft_timeout occurs after keepalive is set, then the main child
8185 loop would try to read another request even though the connection
8186 has been aborted. [Roy Fielding]
8188 *) Configure changes: Allow for whitespace at the start of a
8189 Module declaration. Also, be more understanding about the
8190 CC=/OPTIM= format in Configuration. Finally, fix compiler
8191 flags if using HP-UX's cc compiler. [Jim Jagielski]
8193 *) Subrequests and internal redirects now inherit the_request from the
8194 original request-line. [Roy Fielding]
8196 *) Test for error conditions before creating output header fields, since
8197 we don't want the error message to include those fields. Likewise,
8198 reset the content_language(s) and content_encoding of the response
8199 before generating or redirecting to an error message, since the new
8200 message will have its own Content-* definitions. [Dean Gaudet]
8202 *) Restored the semantics of headers_out (headers sent only with 200..299
8203 and 304 responses) and err_headers_out (headers sent with all responses).
8204 Avoid the overhead of copying tables if err_headers_out is empty
8205 (the usual case). [Roy Fielding]
8207 *) Fixed a couple places where a check for the default Content-Type was
8208 not properly checking both the value configured by the DefaultType
8209 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8210 of DEFAULT_TYPE to match the documented default (text/plain).
8211 [Dean Gaudet] PR#506
8213 *) Escape the HTML-sensitive characters in the Request-URI that is
8214 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8216 *) Properly initialize the flock structures used by the mutex locking
8217 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8220 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8221 (and NCSA httpd) definition wherein it was the extra path info beyond
8222 the CGI script filename. The environment variable FILEPATH_INFO has
8223 been removed, and instead we supply the original REQUEST_URI to any
8224 script that wants to be Apache-specific and needs the real URI path.
8225 This solves a problem with existing scripts that use extra path info
8226 in the ScriptAlias directive to pass options to the CGI script.
8229 *) The _default_ change in 1.2b10 will change the behaviour on configs
8230 that use multiple Listen statements for listening on multiple ports.
8231 But that change is necessary to make _default_ consistent with other
8232 forms of <VirtualHost>. It requires such configs to be modified
8233 to use <VirtualHost _default_:*>. The documentation has been
8234 updated. [Dean Gaudet] PR#530
8236 *) If an ErrorDocument CGI script is used to respond to an error
8237 generated by another CGI script which has already read the message
8238 body of the request, the server would block trying to read the
8239 message body again. [Rob Hartill]
8241 *) signal() replacement conflicted with a define on QNX (and potentially
8242 other platforms). Fixed. [Ben Laurie] PR#512
8244 Changes with Apache 1.2b10
8246 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8247 to be configured via -D in Configuration. [Dean Gaudet] PR#449

8255 [Chuck Murcko] PR #491
8257 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8258 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8260 Changes with Apache 1.2b9 [never announced]
8262 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8263 changes and in anticipation of 1.2 final release. [Roy Fielding]
8265 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8266 the connection (e.g., when user presses Stop). Apache will now stop
8267 trying to send a message body immediately after an error from write.
8268 [Roy Fielding and Nathan Kurz] PR#335
8270 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8271 than mod_alias, and mod_alias has higher priority than mod_proxy;
8272 rearranged other modules to enhance understanding of their purpose
8273 and relative order (and maybe even reduce some overhead).
8274 [Roy Fielding and Sameer Parekh]
8276 *) Fix graceful restart. Eliminate many signal-related race
8277 conditions in both forms of restart, and in SIGTERM. See
8278 htdocs/manual/stopping.html for details on stopping and
8279 restarting the parent. [Dean Gaudet]
8281 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8282 memory allocator to avoid a behaviour that required extra blocks to
8283 be allocated. [Dean Gaudet]
8285 *) Allow suexec to access files relative to current directory but not
8286 above. (Excluding leading / or any .. directory.) [Ken Coar]
8289 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8290 PR#367, 368, 354, 453
8292 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8293 while obtaining the /~user and save the username in a separate data
8294 area so that it won't be overwritten by the call to getgrgid(), and
8295 fix some misuse of the pool string allocation functions. Also fixes
8296 a general problem with parsing URL query info into args for CGI scripts.

8304 AuthDBAuthoritative. [Marc Slemko] PR#420
8306 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8308 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8309 object that can't be PUT, or FOOBAR for some method FOOBAR that
8310 apache doesn't know about at all). Log 404s that occur in mod_include.
8311 [Paul Sutton, John Van Essen]
8313 *) If a soft timeout (or lingerout) occurs while trying to flush a
8314 buffer or write inside buff.c or fread'ing from a CGI's output,
8315 then the timeout would be ignored. [Roy Fielding] PR#373
8317 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8318 parsing of headers. If the terminating empty-line CRLF occurs starting
8319 at the 256th or 257th byte of output, then Navigator will think a normal
8320 image is invalid. We are guessing that this is because their initial
8321 read of a new request uses a 256 byte buffer. We check the bytes written
8322 so far and, if we are about to tickle the bug, we instead insert a
8323 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8325 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8326 of an external redirection. [Roy Fielding and Paul Sutton]
8328 *) Configure would create a broken Makefile if the configuration file
8329 contained a commented-out Rule. [Roy Fielding]
8331 *) Promote per_dir_config and subprocess_env from the subrequest to the
8332 main request in mod_negotiation. In particular this fixes a bug
8333 where <Files> sections wouldn't properly apply to negotiated content.
8336 *) Fix a potential deadlock in mod_cgi script_err handling.
8337 [Ralf S. Engelschall]
8339 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8342 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8343 .htaccess files because the RewriteBase was not replaced correctly.
8344 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8345 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8347 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8348 1.x the settings are those of pre-1.2b8. For 2.x we include
8349 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8350 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8351 [Dean Gaudet] PR#336, PR#340
8353 *) Redirect did not preserve ?query_strings when present in the client's
8354 request. [Dean Gaudet]
8356 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8358 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8360 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8362 *) Add mod_example (illustration of API techniques). [Ken Coar]
8364 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8366 *) Improve handling of directories when filenames have spaces in them.
8369 *) For hosts with multiple IP addresses, try all additional addresses if
8370 necessary to get a connect. Fail only if hostent address list is
8371 exhausted. [Chuck Murcko]
8373 *) More signed/unsigned port fixes. [Dean Gaudet]
8375 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8378 Changes with Apache 1.2b8
8380 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8381 to it. [Marc Slemko]
8383 *) The addition of <Location> and <File> directives made the
8384 sub_req_lookup_simple() function bogus, so we now handle
8385 the special cases directly. [Dean Gaudet]
8387 *) We now try to log where the server is dumping core when a fatal
8388 signal is received. [Ken Coar]
8390 *) Improved lingering_close by adding a special timeout, removing the
8391 spurious log messages, removing the nonblocking settings (they
8392 are not needed with the better timeout), and adding commentary
8393 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8394 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8396 *) Send error messages about setsockopt failures to the server error
8397 log instead of stderr. [Roy Fielding]
8399 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8401 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8402 processing a subrequest, allocate memory from r->main->pool instead
8403 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8404 in the middle of an SSI request. [Dean Gaudet] PR #122
8406 *) Fixed status of response when POST is received for a nonexistent URL
8407 (was sending 405, now 404) and when any method is sent with a
8408 full-URI that doesn't match the server and the server is not acting
8409 as a proxy (was sending 501, now 403). [Roy Fielding]
8411 *) Host port changed to unsigned short. [Ken Coar] PR #276
8413 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8415 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8417 *) Report extra info from errno with many errors that cause httpd to exit.
8418 spawn_child, popenf, and pclosef now have valid errno returns in the
8419 event of an error. Correct problems where errno was stomped on
8420 before being reported. [Dean Gaudet]
8422 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8423 never called, and thus the filesystem would remain full indefinitely.
8424 We now also remove incomplete cache files left if the origin server
8425 didn't send a Content-Length header and either the client has aborted
8426 transfer or bwrite() to client has failed. [Petr Lampa]
8428 *) Fixed the handling of module and script-added header fields.
8429 Improved the interface for sending header fields and reduced
8430 the duplication of code between sending okay responses and errors.
8431 We now always send both headers_out and err_headers_out, and
8432 ensure that the server-reserved fields are not being overridden,
8433 while not overriding those that are not reserved. [Roy Fielding]
8435 *) Moved transparent content negotiation fields to err_headers_out
8436 to reflect above changes. [Petr Lampa]
8438 *) Fixed the determination of whether or not we should make the
8439 connection persistent for all of the cases where some other part
8440 of the server has already indicated that we should not. Also
8441 improved the ordering of the test so that chunked encoding will
8442 be set whenever it is desired instead of only when KeepAlive
8443 is enabled. Added persistent connection capability for most error
8444 responses (those that do not indicate a bad input stream) when
8445 accessed by an HTTP/1.1 client. [Roy Fielding]
8447 *) Added missing timeouts for sending header fields, error responses,
8448 and the last chunk of chunked encoding, each of which could have
8449 resulted in a process being stuck in write forever. Using soft_timeout
8450 requires that the sender check for an aborted connection rather than
8451 continuing after an EINTR. Timeouts that used to be initiated before
8452 send_http_header (and never killed) are now initiated only within or
8453 around the routines that actually do the sending, and not allowed to
8454 propagate above the caller. [Roy Fielding]
8456 *) mod_auth_anon required an @ or a . in the email address, not both.
8459 *) per_dir_defaults weren't set correctly until directory_walk for
8460 name-based vhosts. This fixes an obscure bug with the wrong config
8461 info being used for vhosts that share the same ip as the server.
8464 *) Improved generation of modules/Makefile to be more generic for
8465 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8467 *) Generate makefile dependency for Configuration based on the actual
8468 name given when running the Configure process. [Dean Gaudet]
8470 *) Fixed problem with vhost error log not being set prior to
8471 initializing virtual hosts. [Dean Gaudet]
8473 *) Fixed infinite loop when a trailing slash is included after a type map
8474 file URL (extra path info). [Petr Lampa]
8476 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8478 *) Add documentation for DNS issues (reliability and security), and try
8479 to explain the virtual host matching process. [Dean Gaudet]
8481 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8482 fails while parsing the configuration file. [Dean Gaudet]
8484 *) Improved calls to setsockopt. [Roy Fielding]
8486 *) Negotiation changes: Don't output empty content-type in variant list;
8487 Output charset in variant list; Return sooner from handle_multi() if
8488 no variants found; Add handling of '*' wildcard in Accept-Charset.
8489 [Petr Lampa and Paul Sutton]
8491 *) Fixed overlaying of request/sub-request notes and headers in
8492 mod_negotiation. [Dean Gaudet]
8494 *) If two variants' charset quality are equal and one is the default
8495 charset (iso-8859-1), then prefer the variant that was specifically
8496 listed in Accept-Charset instead of the default. [Petr Lampa]
8498 *) Memory allocation problem in push_array() -- it would corrupt memory
8499 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8501 *) invoke_handler() doesn't handle mime arguments in content-type
8504 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8507 *) Fixed problem with ErrorDocument not working for virtual hosts
8508 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8510 *) Log an error message if we get a request header that is too long,
8511 since it may indicate a buffer overflow attack. [Marc Slemko]
8513 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8514 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8515 [Ken Coar] PR #146, #187
8517 *) Added table entry placeholder for new header_parser callback
8518 in all of the distributed modules. [Ken Coar] PR #191
8520 *) Allow for cgi files without the .EXE extension on them under OS/2.
8521 [Garey Smiley] PR #59
8523 *) Fixed error message when resource is not found and URL contains
8524 path info. [Petr Lampa and Dean Gaudet] PR #40
8526 *) Fixed user and server confusion over what should be a virtual host
8527 and what is the main server, resulting in access to something
8528 other than the name defined in the virtualhost directive (but
8529 with the same IP address) failing. [Dean Gaudet]
8531 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8532 AIX; improves the redirection stuff to enable the users to generally
8533 redirect to http, https, gopher and ftp; added TIME variable for
8534 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8535 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8536 can be used in conjunction with %{TIME} or other variables to create
8537 time-dependent rewriting rules. [Ralf S. Engelschall]
8539 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8540 Module authors may need to adjust their code for proper cleanup to take
8541 place (that is, call note_cleanups_for_fd()). This change fixes problems
8542 with file descriptors being erroneously closed when the proxy module was
8543 in use. [Ben Laurie]
8545 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8546 initgroups() to hose the group information needed for later
8547 comparisons. [Randy Terbush]
8549 *) Remove unnecessary call to va_end() in create_argv() which
8550 caused a SEGV on some systems.
8552 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8555 *) Clear memory allocated for listeners. [Randy Terbush]
8557 *) Improved handling of IP address as a virtualhost address and
8558 introduced "_default_" as a synonym for the default vhost config.
8559 [Dean Gaudet] PR #212
8561 Changes with Apache 1.2b7
8563 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
8565 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
8567 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8568 - replace protocol response numbers with symbols
8569 - save variant-list into main request notes
8570 - free allocated memory from subrequests
8571 - merge notes, headers_out and err_headers_out
8573 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8574 "HTTP/#.# ###*" to be more lenient about what we accept.
8577 *) more proxy FTP bug fixes:
8578 - Changed send_dir() to remove user/passwd from displayed URL.
8579 - Changed login error messages to be more descriptive.
8580 - remove setting of SO_DEBUG socket option
8581 - Make ftp_getrc() more lenient about multiline responses,
8582 specifically, 230 responses which don't have continuation 230-
8583 on each line). These seem to be all NT FTP servers, and while
8584 perhaps questionable, they appear to be legal by RFC 959.
8585 - Add missing kill_timeout() after transfer to user completes.
8588 *) Fixed problem where a busy server could hang when restarting
8589 after being sent a SIGHUP due to child processes not exiting.
8592 *) Modify mod_include escaping so a '\' only signifies an escaped
8593 character if the next character is one that needs
8594 escaping. [Ben Laurie]
8596 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8597 used with a 'base' directive that does not have a '/' in it.
8598 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8600 *) Reduced the default timeout from 1200 seconds to 300, and the
8601 one in the sample configfile from 400 to 300. [Marc Slemko]
8603 *) Stop vbprintf from crashing if given a NULL string pointer;
8604 print (null) instead. [Ken Coar]
8606 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8607 [Marc Slemko and Roy Fielding]
8609 *) Fixed problem with mod_cgi-generated internal redirects trying to
8610 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8612 *) Reduced timeout on lingering close, removed possibility of a blocked
8613 read causing the child to hang, and stopped logging of errors if
8614 the socket is not connected (reset by client). [Roy Fielding]
8616 *) Rearranged main child loop to remove duplication of code in
8617 select/accept and keep-alive requests, fixed several bugs regarding
8618 checking scoreboard_image for exit indication and failure to
8619 account for all success conditions and trap all error conditions,
8620 prevented multiple flushes before closing the socket; close the entire
8621 socket buffer instead of just one descriptor, prevent logging of
8622 EPROTO and ECONNABORTED on platforms where supported, and generally
8623 improved readability. [Roy Fielding]
8625 *) Extensive performance improvements. Cleaned up inefficient use of
8626 auto initializers, multiple is_matchexp calls on a static string,
8627 and excessive merging of response_code_strings. [Dean Gaudet]
8629 *) Added double-buffering to mod_include to improve performance on
8630 server-side includes. [Marc Slemko]
8632 *) Several fixes for suexec wrapper. [Randy Terbush]
8633 - Make wrapper work for files on NFS filesystem.
8634 - Fix portability problem of MAXPATHLEN.
8635 - Fix array overrun problem in clean_env().
8636 - Fix allocation of PATH environment variable
8638 *) Removed extraneous blank line is description of mod_status chars.
8641 *) Logging of errors from the call_exec routine simply went nowhere,
8642 since the logfile fd has been closed, so now we send them to stderr.
8643 [Harald T. Alvestrand]
8645 *) Fixed core dump when DocumentRoot is a CGI.
8646 [Ben Laurie, reported by geddis@tesserae.com]
8648 *) Fixed potential file descriptor leak in mod_asis; updated it and
8649 http_core to use pfopen/pfclose instead of fopen/fclose.
8650 [Randy Terbush and Roy Fielding]
8652 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8653 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8654 [Dean Gaudet and Ken Coar]
8656 *) Return a 302 response code to the client when sending a redirect
8657 due to a missing trailing '/' on a directory instead of a 301; now
8658 it is cacheable. [Markus Gyger]
8660 *) Fix condition where, if a bad directive occurs in .htaccess, and
8661 sub_request() goes first to this directory, then log_reason() will
8662 SIGSEGV because it doesn't have initialized r->per_dir_config.
8663 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8665 *) Fix handling of lang_index in is_variant_better(). This was
8666 causing problems which resulted in the server sending the
8667 wrong language document in some cases. [Petr Lampa]
8669 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8670 the clean environment on some systems.
8672 *) Tweak byteserving code (e.g. serving PDF files) to work around
8673 bugs in Netscape Navigator and Microsoft Internet Explorer.
8674 Emit Content-Length header when sending multipart/byteranges.
8677 *) Port to HI-UX/WE2. [Nick Maclaren]
8679 *) Port to HP MPE operating system for HP 3000 machines
8680 [Mark Bixby <markb@cccd.edu>]
8682 *) Fixed bug which caused a segmentation fault if only one argument
8683 given to RLimit* directives. [Ed Korthof]
8685 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8687 *) Improved buffered output to the client by delaying the flush decision
8688 until the BUFF code is actually about to read the next request.
8689 This fixes a problem introduced in 1.2b5 with clients that send
8690 an extra CRLF after a POST request. Also improved chunked output
8691 performance by combining writes using writev() and removing as
8692 many bflush() calls as possible. NOTE: Platforms without writev()
8693 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8694 or Configure, unless we have already done so. [Dean Gaudet]
8696 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8698 *) Fixed mod_info output corruption bug introduced by buffer overflow
8699 fixes. [Dean Gaudet]
8701 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8702 for the special case of a 304 response. [Paul Sutton]
8704 *) Improved handling of TRACE method by bypassing normal method handling
8705 and header parsing routines; fixed Allow response to always allow TRACE.
8708 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8710 *) Cleaned-up some of the generated HTML. [Ken Coar]
8712 Changes with Apache 1.2b6
8714 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8716 *) Fix typo introduced in fix for potential infinite loop around
8717 accept() in child_main(). This change caused the rev to 1.2b6.
8718 1.2b5 was never a public beta.
8720 Changes with Apache 1.2b5
8722 *) Change KeepAlive semantics (On|Off instead of a number), add
8723 MaxKeepAliveRequests directive. [Alexei Kosut]
8725 *) Various NeXT compilation patches, as well as a change in
8726 regex/regcomp.c since that file also used a NEXT define.
8729 *) Allow * to terminate the end of a directory match in mod_dir.
8730 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8732 *) Don't call can_exec() if suexec_enabled. Calling this requires
8733 scripts executed by the suexec wrapper to be world executable, which
8734 defeats one of the advantages of running the wrapper. [Randy Terbush]
8736 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8739 *) Migration from sprintf() to snprintf() to avoid buffer
8740 overflows. [Marc Slemko]
8742 *) Provide portable snprintf() implementation (ap_snprintf)
8743 as well as *cvt family. [Jim Jagielski]
8745 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8748 *) Remove mod_fastcgi.c from the distribution. This module appears
8749 to be maintained more through the Open Market channels and should
8750 continue to be easily available at http://www.fastcgi.com/
8752 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8753 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8755 *) mod_info assumed that the config files were relative to ServerRoot.
8758 *) CGI scripts called as an error document resulting from failed
8759 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8761 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8764 *) Properly check errno to prevent display of a directory index
8765 when server receives a long enough URL to confuse stat().
8768 *) Several security enhancements to suexec wrapper. It is _highly_
8769 recommended that previously installed versions of the wrapper
8770 be replaced with this version. [Randy Terbush, Jason Dour]
8772 - ~user execution now properly restricted to ~user's home
8773 directory and below.
8774 - execution restricted to UID/GID > 100
8775 - restrict passed environment to known variables
8776 - call setgid() before initgroups() (portability fix)
8777 - remove use of setenv() (portability fix)
8779 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8781 *) Add access control via environment variables. [Ben Laurie]
8783 *) Add rflush() function. [Alexei Kosut]
8785 *) remove duplicate pcalloc() call in new_connection().
8787 *) Fix incorrect comparison which could allow number of children =
8788 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8789 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8791 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8792 AIX PS/2, CONVEXOS. [Jim Jagielski]
8794 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8795 It's more portable. [Martin Kraemer]
8797 *) Replace references to make in Makefile.tmpl with $(MAKE).
8800 *) Add ProxyBlock directive w/IP address caching. Add IP address
8801 caching to NoCache directive as well. ProxyBlock works with all
8802 handlers; NoCache now also works with FTP for anonymous logins.
8803 Still more code cleanup. [Chuck Murcko]
8805 *) Add "header parse" API hook [Ben Laurie]
8807 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8809 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8811 *) Correctly allow access and auth directives in <Files> sections in
8812 server config files. [Alexei Kosut]
8814 *) Fix bug with ServerPath that could cause certain files to be not
8815 found by the server. [Alexei Kosut]
8817 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8818 double-quote from text and so that it properly checks for unsupported
8819 status codes using the new index_of_response interface. [Roy Fielding]
8821 *) Multiple fixes to the lingering_close code in order to avoid being
8822 interrupted by a stray timeout, to avoid lingering on a connection
8823 that has already been aborted or never really existed, to ensure that
8824 we stop lingering as soon as any error condition is received, and to
8825 prevent being stuck indefinitely if the read blocks. Also improves
8826 reporting of error conditions. [Marc Slemko and Roy Fielding]
8828 *) Fixed initialization of parameter structure for sigaction.
8829 [mgyger@itr.ch, Adrian Filipi-Martin]
8831 *) Fixed reinitializing the parameters before each call to accept and
8832 select, and removed potential for infinite loop in accept.
8833 [Roy Fielding, after useful PR from adrian@virginia.edu]
8835 *) Fixed condition where, if a child fails to fork, the scoreboard would
8836 continue to say SERVER_STARTING forever. Eventually, the main process
8837 would refuse to start new children because count_idle_servers() will
8838 count those SERVER_STARTING entries and will always report that there
8839 are enough idle servers. [Phillip Vandry]
8841 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8842 Avoided calling bflush() when the client is pipelining requests.
8843 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8845 *) Added description of "." mode in server-status [Jim Jagielski]
8847 Changes with Apache 1.2b4
8849 *) Fix possible race condition in accept_mutex_init() that
8850 could leave a small security hole open allowing files to be
8851 overwritten in cases where the server UID has write permissions.
8854 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8856 *) Fix portablity problem in util_script where ARG_MAX may not be
8857 defined for some systems.
8859 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8862 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8863 style magic #! token for better script portability. [Garey Smiley]
8865 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8866 execution for ~userdir CGI. [Jason Dour]
8868 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8870 *) Fix month off by one in suexec wrapper logging.
8872 Changes with Apache 1.2b3:
8874 *) Fix error in mod_cgi which could cause resources not to be properly
8875 freed, or worse. [Dean Gaudet]
8877 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8879 *) Add set_flag_slot() at the request of Dirk and others.
8882 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8884 *) Add changes to improve the error message given for invalid
8885 ServerName parameters. [Dirk vanGulik]
8887 *) Add "Authoritative" directive for Auth modules that don't
8888 currently have it. This gives admin control to assign authoritative
8889 control to an authentication scheme and allow "fall through" for
8890 those authentication modules that aren't "Authoritative" thereby
8891 allowing multiple authentication mechanisms to be chained.
8894 *) Remove requirement for ResourceConfig/AccessConfig if not using
8895 the three config file layout. [Randy Terbush]
8897 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8899 *) Changes to suexec wrapper to fix the following problems:
8900 1. symlinked homedirs will kill ~userdirs.
8901 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8902 3. CGI command lines paramters problems
8903 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8904 [Randy Terbush, Jason Dour]
8906 *) Change create_argv() to accept variable arguments. This fixes
8907 a problem where arguments were not getting passed to the CGI via
8908 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8910 *) Collapse multiple slashes in path URLs to properly apply
8911 handlers defined by <Location>. [Alexei Kosut]
8913 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8915 *) Improve the accuracy of request duration timings by setting
8916 r->request_time in read_request_line() instead of read_request().
8919 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8920 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8922 *) Add the ability to pass different Makefile.tmpl files to Configure
8923 using the -make flag. [Rob Hartill]
8925 *) Fix coredump triggered when sending a SIGHUP to the server caused
8926 by an assertion failure, in turn caused by an uninitialised field in a
8930 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8931 PATH_INFO from previous versions of Apache (in certain situations,
8932 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8933 [later removed in 1.2b11]
8935 *) Add rwrite() function to API to allow for sending strings of
8936 arbitrary length. [Doug MacEachern]
8938 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8940 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8941 NeXT. [Jim Jagielski]
8943 *) Removed recent modification to promote the status code on internal
8944 redirects, since the correct fix was to change the default log format
8945 in mod_log_config so that it outputs the original status. [Rob Hartill]
8947 Changes with Apache 1.2b2:
8949 *) Update set_signals() to use sigaction() for setting handlers.
8950 This appears to fix a re-entrant problem in the seg_fault()
8951 bus_error() handlers. [Randy Terbush]
8953 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8955 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8957 *) proxy_http.c bugfixes: [Chuck Murcko]
8958 1) fixes possible NULL pointer reference w/NoCache
8959 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8960 host would cache nothing if it was in the local domain,
8961 and the local domain was in the NoCache list)
8962 3) Adds Host: header when not available
8963 4) Some code cleanup and clarification
8965 *) mod_include.c bugfixes:
8966 1) Fixed an ommission that caused include variables to not
8967 be parsed in config errmsg directives [Howard Fear]
8968 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8969 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8970 4) Allow backslash-escaping to all quoted text
8971 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8972 5) Pass variable to command line if not set in XSSI's env
8975 *) Fix infinite loop when processing Content-language lines in
8976 type-map files. [Alexei Kosut]
8978 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8980 *) Fixed problem in set_[user|group] that prevented CGI execution
8981 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8983 *) Added PORTING information file. [Jim Jagielski]
8985 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8987 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8989 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8990 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8992 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8993 which caused problems of systems where socket s_addr is >32bits.
8995 *) Added comment to explain (r->chunked = 1) side-effect in
8996 http_protocol.c [Roy Fielding]
8998 *) Replaced use of index() in mod_expires.c with more appropriate
8999 and portable isdigit() test. [Ben Laurie]
9001 *) Updated Configure for ...
9002 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
9003 *-dg-dgux* (bad pattern match)
9004 QNX (DEF_WANTHSREGEX=yes)
9005 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
9008 and added some user diagnostic info. [Ben Laurie]
9010 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
9011 for better portability. [Jim Jagielski]
9013 *) Updated helpers/GuessOS for ...
9014 SCO 5 (recognize minor releases)
9015 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
9016 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
9017 IRIX64 (-sgi-irix64)
9018 ULTRIX (-unknown-ultrix)
9019 SINIX (-whatever-sysv4)
9020 NCR Unix (-ncr-sysv4)
9021 and fixed something in helpers/PrintPath [Ben Laurie]
9023 Changes with Apache 1.2b1
9025 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
9027 Changes with Apache 1.1.1
9029 *) Fixed bug where Cookie module would make two entries in the
9030 logfile for each access [Mark Cox]
9032 *) Fixed bug where Redirect in .htaccess files would cause memory
9033 leak. [Nathan Neulinger]
9035 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9037 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9039 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9041 Changes with Apache 1.1.0
9043 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9045 *) Bring QNX support up to date. [Ben Laurie]
9047 *) Make virtual hosts default to main server keepalive parameters.
9048 [Alexei Kosut, Ben Laurie]
9050 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9052 *) Fix missing address family for connect, also remove unreachable statement
9053 in mod_proxy. [Ben Laurie]
9055 *) mod_env now turned on by default in Configuration.tmpl.
9057 *) Bugs which were fixed:
9058 a) yet more mod_proxy bugs [Ben Laurie]
9059 b) CGI works again with inetd [Alexei Kosut]
9060 c) Leading colons were stripped from passwords [osm@interguide.com]
9061 d) Another fix to multi-method Limit problem [jk@tools.de]
9063 Changes with Apache 1.1b4
9065 *) r->bytes_sent variable restored. [Robert Thau]
9067 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9069 *) More possibly unsecure programs removed from the support directory.
9071 *) More mod_auth_msql authentication improvements.
9073 *) VirtualHosts based on Host: headers no longer conflict with the
9076 *) OS/2 compatibility enhancements. [Gary Smiley]
9078 *) POST now allowed to directory index CGI scripts.
9080 *) Actions now work with files of the default type.
9082 *) Bugs which were fixed:
9083 a) more mod_proxy bugs
9084 b) early termination of inetd requests
9085 c) compile warnings on several systems
9086 d) problems when scripts stop reading output early
9088 Changes with Apache 1.1b3
9090 *) Much of cgi-bin and all of cgi-src has been removed, due to
9091 various security holes found and that we could no longer support
9094 *) The "Set-Cookie" header is now special-cased to not merge multiple
9095 instances, since certain popular browsers can not handle multiple
9096 Set-Cookie instructions in a single header. [Paul Sutton]
9098 *) rprintf() added to buffer code, occurrences of sprintf removed.
9101 *) CONNECT method for proxy module, which means tunneling SSL should work.
9102 (No crypto needed) Also a NoCache config directive.
9104 *) Several API additions: pstrndup(), table_unset() and get_token()
9105 functions now available to modules.
9107 *) mod_imap fixups, in particular Location: headers are now complete
9110 *) New "info" module which reports on installed module set through a
9111 special URL, a la mod_status.
9113 *) "ServerPath" directive added - allows for graceful transition
9114 for Host:-header-based virtual hosts.
9116 *) Anonymous authentication module improvements.
9118 *) MSQL authentication module improvements.
9120 *) Status module design improved - output now table-based. [Ben Laurie]
9122 *) htdigest utility included for use with digest authentication
9125 *) mod_negotiation: Accept values with wildcards to be treated with
9126 less priority than those without wildcards at the same quality
9127 value. [Alexei Kosut]
9129 *) Bugs which were fixed:
9130 a) numerous mod_proxy bugs
9131 b) CGI early-termination bug [Ben Laurie]
9132 c) Keepalives not working with virtual hosts
9133 d) RefererIgnore problems
9134 e) closing fd's twice in mod_include (causing core dumps on
9135 Linux and elsewhere).
9137 Changes with Apache 1.1b2
9140 a) core dumps in mod_digest
9141 b) truncated hostnames/ip address in the logs
9142 c) relative URL's in mod_imap map files
9144 Changes with Apache 1.1b1
9146 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9148 Changes with Apache 1.0.3
9150 *) Internal redirects which occur in mod_dir.c now preserve the
9151 query portion of a request (the bit after the question mark).
9154 *) Escape active characters '<', '>' and '&' in html output in
9155 directory listings, error messages and redirection links.
9158 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9160 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9163 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9165 *) Reset timeout timer after each successful fwrite() to the network.
9166 This patch adds a reset_timeout() procedure that is called by
9167 send_fd() to reset the timeout ever time data is written to the net.
9170 *) timeout() signal handler now checks for SIGPIPE and reports
9171 lost connections in a more user friendly way. [Rob Hartill]
9173 *) Location of the "scoreboard" file which used to live in /tmp is
9174 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9175 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9177 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9179 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9180 which caused a SEGV with cookies enabled
9182 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9185 *) Log the UNIX textual error returned by some system calls, in
9186 particular errors from accept() [David Robinson]
9188 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9190 Changes with Apache 1.0.2
9192 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9193 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9195 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9198 *) past changes to http_config.c to only use the
9199 setrlimit function on systems defining RLIMIT_NOFILE
9200 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9201 for SUNOS and prototypes the needed functions.
9203 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9206 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9208 *) Merge multiple headers from CGI scripts instead of taking last
9209 one. [David Robinson]
9211 *) Add support for SCO 5. [Ben Laurie]
9213 Changes with Apache 1.0.1
9215 *) Silence mod_log_referer and mod_log_agent if not configured
9218 *) Recursive includes can occur if the client supplies PATH_INFO data
9219 and the server provider uses relative links; as file.html
9220 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9222 *) The replacement for initgroups() did not call {set,end}grent(). This
9223 had two implications: if anything else used getgrent(), then
9224 initgroups() would fail, and it was consuming a file descriptor.
9227 *) On heavily loaded servers it was possible for the scoreboard to get
9228 out of sync with reality, as a result of a race condition.
9229 The observed symptoms are far more Apaches running than should
9230 be, and heavy system loads, generally followed by catastrophic
9231 system failure. [Ben Laurie]
9233 *) Fix typo in license. [David Robinson]
9235 Changes with Apache 1.0.0 23 Nov 1995
9237 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9239 Changes with Apache 0.8.16 05 Nov 1995
9241 *) New man page for 'httpd' added to support directory [David Robinson]
9243 *) .htgroup files can have more than one line giving members for a
9244 given group (each must have the group name in front), for NCSA
9245 back-compatibility [Robert Thau]
9247 *) Mutual exclusion around accept() is on by default for SVR4 systems
9248 generally, since they generally can't handle multiple processes in
9249 accept() on the same socket. This should cure flaky behavior on
9250 a lot of those systems. [David Robinson]
9252 *) AddType, AddEncoding, and AddLanguage directives take multiple
9253 extensions on a single command line [David Robinson]
9255 *) UserDir can be disabled for a given virtual host by saying
9256 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9257 that this didn't work. [David Robinson]
9259 *) Compiles on QNX [Ben Laurie]
9261 *) Corrected parsing of ctime time format [David Robinson]
9263 *) httpd does a perror() before exiting if it can't log its pid
9264 to the PidFile, to make diagnosing the error a bit easier.
9267 *) <!--#include file="..."--> can no longer include files in the
9268 parent directory, for NCSA back-compatibility. [David Robinson]
9270 *) '~' is *not* escaped in URIs generated for directory listings
9273 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9275 *) Fixed bug involving handling URIs with escaped %-characters
9276 in redirects [David Robinson]
9278 Changes with Apache 0.8.15 14 Oct 1995
9280 *) Switched to new, simpler license
9282 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9284 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9286 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9288 *) Correctly handles internal redirects to files with names containing '%'
9291 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9293 *) Use geteuid() rather than getuid() to see if we have root privilege,
9294 so that server correctly resets privilege if run setuid root. [Andrew
9297 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9300 *) Fix relative URLs in imagemap files [Randy Terbush]
9302 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9305 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9306 entries all name the same one. [David Robinson]
9308 *) Fix directory listings with filenames containing unusual characters
9311 *) Better URI-escaping for generated URIs in directories with filenames
9312 containing unusual characters [Ben Laurie]
9314 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9316 *) Unblock alarms on error return from spawn_child() [David Robinson]
9318 *) Sample Config files have extra note for SCO users [Ben Laurie]
9320 *) Configuration has note for HP-UX users [Rob Hartill]
9322 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9324 *) Nuked bogus #define in httpd.h [David Robinson]
9326 *) Better test for whether a system has setrlimit() [David Robinson]
9328 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9330 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9333 Changes with Apache 0.8.14 19 Sep 1995
9335 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9337 *) AddDescription works (better) [Ben Laurie]
9339 *) Leaves an intelligible error diagnostic when it can't set group
9340 privileges on standalone startup [Andrew Wilson]
9342 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9343 that machine, which claims to be BSD but does not support RLIMIT.
9346 *) gcc -Wall no longer complains about an unused variable when util.c
9347 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9349 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9351 Changes with Apache 0.8.13 07 Sep 1995
9353 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9355 *) Have built-in imagemap code recognize & honor Point directive [James
9358 *) Generate cleaner directory listings in directories with a mix of
9359 long and short filenames [Rob Hartill]
9361 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9363 *) Properly default ServerName for virtual servers [Robert Thau]
9365 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9366 Paul Richards and a cast of thousands...]
9368 *) On self-identified BSD systems (we don't try to guess any more),
9369 allocate a few extra file descriptors per virtual host with setrlimit,
9370 if we can, to avoid running out. [Randy Terbush]
9372 *) Write 22-character lock file name into buffer with enough space
9373 on startup [Konstantin Olchanski]
9375 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9378 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9380 *) Suppress -Wall warning by initializing variable in negotiation code
9381 [Tobias Weingartner]
9383 Changes with Apache 0.8.12 31 Aug 1995
9385 *) Doesn't pause three seconds after including a CGI script which is
9386 too slow to die off (this is done by not even trying to kill off
9387 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9388 after the entire document has been processed). [Robert Thau]
9390 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9392 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9394 *) Allows .htaccess files to override <Directory> sections naming the
9395 same directory [David Robinson]
9397 *) Removed an efficiency hack in sub_req_lookup_uri which was
9398 causing certain extremely marginal cases (e.g., ScriptAlias of a
9399 *particular* index.html file) to fail. [David Robinson]
9401 *) Doesn't log an error when the requested URI requires
9402 authentication, but no auth header line was supplied by the
9403 client; this is a normal condition (the client doesn't no auth is
9404 needed here yet). [Robert Thau]
9406 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9408 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9410 *) RFC931 code no longer passes out name of prior clients on current
9411 requests if the current request came from a server that doesn't
9412 do RFC931. [David Robinson]
9414 *) Configuration script accepts "Module" lines with trailing whitespace.
9417 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9419 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9421 Changes with Apache 0.8.11 24 Aug 1995
9423 *) Wildcard <Directory> specifications work. [Robert Thau]
9425 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9427 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9428 the file being requested itself, in addition to the directories leading
9429 up to it. [Robert Thau]
9431 *) Logs access failures due to symlink checks or invalid client address
9432 in the error log [Roy Fielding, Robert Thau]
9434 *) Symlink checks deal correctly with systems where lstat of
9435 "/path/to/some/link/" follows the link. [Thau, Fielding]
9437 *) Doesn't reset DirectoryIndex to 'index.html' when
9438 other directory options are set in a .htaccess file. [Robert Thau]
9440 *) Clarified init code and nuked bogus warning in mod_access.c
9443 *) Corrected several directives in sample srm.conf
9444 --- includes corrections to directory indexing icon-related directives
9445 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9446 icons for encodings right, and turning on AddEncoding by default).
9449 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9452 *) INSTALL & README mention "contributed modules" directory [Brian
9455 *) Fixed English in the license language... "for for" --> "for".
9458 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9459 mod_alias.c, merging it almost completely with handling of Alias, and
9460 adding a 'notes' field to the request_rec which allows the CGI module
9461 to discover whether the Alias module has put this request through
9462 ScriptAlias (which it needs to know for back-compatibility, as the old
9463 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9466 Changes with Apache 0.8.10 18 Aug 1995
9468 *) AllowOverride applies to the named directory, and not just
9469 subdirectories. [David Robinson]
9471 *) Do locking for accept() exclusion (on systems that need it)
9472 using a special file created for the purpose in /usr/tmp, and
9473 not the error log; using the error log causes real problems
9474 if it's NFS-mounted; this is known to be the cause of a whole
9475 lot of "server hang" problems with Solaris. [David Robinson;
9476 thanks to Merten Schumann for help diagnosing the problem].
9478 Changes with Apache 0.8.9 12 Aug 1995
9480 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9482 *) Nested includes see environment variables of the including document,
9483 for NCSA bug-compatibility (some sites have standard footer includes
9484 which try to print out the last-modified date). [Eric Hagberg/Robert
9487 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9488 URI as a CGI script, even if it would have been treated as something
9489 else if requested directly, for NCSA back-compatibility. (Note that
9490 this means that people who know the name of the script can see the
9491 code just by asking for it). [Robert Thau]
9493 *) New version of dbmmanage script included in support directory as
9496 *) Check if scoreboard file couldn't be opened, and say so, rather
9497 then going insane [David Robinson]
9499 *) POST to CGI works on A/UX [Jim Jagielski]
9501 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9503 *) NCSA server push works properly --- the Arena bug compatibility
9504 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9505 if you still want the workaround). [Rob Hartill]
9507 *) If client didn't submit any Accept-encodings, ignore encodings in
9508 content negotiation. (NB this will all have to be reworked anyway
9509 for the new HTTP draft). [Florent Guillaume]
9511 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9513 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9515 *) Give Redirect priority over Alias, for NCSA bug compatibility
9518 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9519 paralleling earlier bug fix for CGI [David Robinson]
9521 *) If DBM auth is improperly configured, report a server error and don't
9524 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9525 it seems to work well enough without it (even in a 10 hits/sec
9526 workout), and the overhead for the locking under A/UX is
9527 alarmingly high (though it is very low on other systems).
9528 [Eric Hagberg, Jim Jagielski]
9530 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9532 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9533 Behlendorf/Eric Hagberg]
9535 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9537 *) Compiles clean on NEXT [Rob Hartill]
9539 *) Compiles clean on SGI [Robert Thau]
9541 Changes with Apache 0.8.8 08 Aug 1995
9543 *) SunOS library prototypes now never included unless explicitly
9544 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9545 people using GNU libc on SunOS are screwed by prototypes for the
9548 (Those who wish to compile clean with gcc -Wall on a standard
9549 SunOS setup need the prototypes, and may obtain them using
9550 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9551 with nonstandard libraries are presumably competent to make their
9554 *) Strips trailing '/' characters off both args to the Alias command,
9555 to make 'Alias /foo/ /bar/' work.
9557 Changes with Apache 0.8.7 03 Aug 1995
9559 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9560 [reported by David Robinson]
9562 *) Compiles clean on OSF/1 [David Robinson]
9564 *) Added some of the more recent significant changes (AddLanguage stuff,
9565 experimental LogFormat support) to CHANGES file in distribution root
9568 Changes with Apache 0.8.6 02 Aug 1995
9570 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9571 (If you actually wanted a conditional GET which bypassed the cache, you
9572 couldn't get it). [Reported by Roy Fielding]
9574 *) Properly terminate headers on '304 Not Modified' replies to conditional
9575 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9576 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9578 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9580 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9581 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9582 and older versions don't set the __SUNPRO_C preprocessor variable). On
9583 all other systems, these are never used anyway. [Reported by Mark Cox].
9585 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9587 Changes with Apache 0.8.5 01 Aug 1995
9589 *) Added last-minute configurable log experiment, as optional module
9591 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9592 properly. (One-line fix to http_protocol.c).
9594 *) Work around bogus behavior when reloading from Netscape.
9595 It's Netscape's bug --- for some reason they expect a request with
9596 If-modified-since: to not function as a conditional GET if it also
9597 comes with Pragma: no-cache, which is way out of line with the HTTP
9598 spec (according to Roy Fielding, the redactor).
9600 *) Added parameter to set maximum number of server processes.
9602 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9605 *) IdentityCheck bugfix [Chuck Murcko].
9607 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9609 *) More sample config file corrections; add extension to AddType for
9610 *.asis, move AddType generic description to its proper place, and
9611 fix miscellaneous typos. [ Alexei Kosut ]
9613 *) Deleted the *other* reference to the regents from the Berkeley
9614 legal disclaimer (everyplace).
9616 *) Nuked Shambhala name from src/README; had already cleaned it out
9619 Changes with Apache 0.8.4
9621 *) Changes to server-pool management parms --- renamed current
9622 StartServers to MinSpareServers, created separate StartServers
9623 parameter which means what it says, and renamed MaxServers to
9624 MaxSpareServers (though the old name still works, for NCSA 1.4
9625 back-compatibility). The old names were generally regarded as
9626 too confusing. Also altered "docs" in sample config files.
9628 *) More improvements to default config files ---
9629 sample directives (commented out) for XBitHack, BindAddress,
9630 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9631 defaults, AddTypes for send-as-is and imagemap magic types, and
9632 improvements to samples for DirectoryIndex [Alexei Kosut]
9634 *) Yet more improvements to default config files --- changes to
9635 Alexei's sample AddLanguage directives, and sample LanguagePriority
9636 [ Florent Guillaume ]
9638 *) Set config file locations properly if not set in httpd.conf
9641 *) Don't escape URIs in internal redirects multiple times; don't
9642 do that when translating PATH_INFO to PATH_TRANSLATED either.
9645 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9647 Changes with Apache 0.8.3
9649 *) Edited distribution README to *briefly* summarize installation
9650 procedures, and give a pointer to the INSTALL file in the src/
9653 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9654 recent NCSA distributions.
9656 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9657 exist for the same directory, use both and don't segfault. [Reported
9660 *) Proper makefile dependencies [David Robinson]
9662 *) Note (re)starts in error log --- reported by Rob Hartill.
9664 *) Only call no2slash() after get_path_info() has been done, to
9665 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9666 reported by Andrew Wilson, though this one is probably a real bug]
9668 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9669 dump core when Referer is not supplied. [Randy Terbush]
9671 *) Lightly edited sample config files to refer people to our documentation
9672 instead of NCSA's, and to list Rob McCool as *original* author (also
9673 deleted his old, and no doubt non-functional email address). Would be
9674 nice to have examples of new features...
9676 Changes with Apache 0.8.2 19 Jul 1995
9678 *) Added AddLanuage code [Florent Guillaume]
9680 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9682 *) All sorts of problems when MultiViews finds a directory. It would
9683 be nice if mod_dir.c was robust enough to handle that, but for now,
9684 just punt. [reported by Brian Behlendorf]
9686 *) Wait for all children on restart, to make sure that the old socket
9687 is gone and we can reopen it. [reported by Randy Terbush]
9689 *) Imagemap module is enabled in default Configuration
9691 *) RefererLog and UserAgentLog modules properly default the logfile
9694 *) Mark Cox's mod_cookies added to the distribution as an optional
9695 module (commented out in the default Configuration, and noted as
9696 an experiment, along with mod_dld). [Mark Cox]
9698 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9700 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9702 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9704 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9707 Changes with Apache 0.8.1
9709 *) New imagemap module [Randy Terbush]
9711 *) Replacement referer log module with NCSA-compatible RefererIgnore
9712 [Matthew Gray again]
9714 *) Don't mung directory listings with very long filenames.
9717 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9719 *) New config script. See INSTALL for info. [Robert Thau]
9721 *) Scoreboard mechanism for regulating the number of extant server
9722 processes. MaxServers and StartServers defaults are the same as
9723 for NCSA, but the meanings are slightly different. (Actually,
9724 I should probably lower the MaxServers default to 10).
9726 Before asking for a new connection, each server process checks
9727 the number of other servers which are also waiting for a
9728 connection. If there are more than MaxServers, it quietly dies
9729 off. Conversely, every second, the root, or caretaker, process
9730 looks to see how many servers are waiting for a new connection;
9731 if there are fewer than StartServers, it starts a new one. This
9732 does not depend on the number of server processes already extant.
9733 The accounting is arranged through a "scoreboard" file, named
9734 /tmp/htstatus.*, on which each process has an independent file
9735 descriptor (they need to seek without interference).
9737 The end effect is that MaxServers is the maximum number of
9738 servers on an *inactive* server machine, but more will be forked
9739 off to handle unusually heavy loads (or unusually slow clients);
9740 these will die off when they are no longer needed --- without
9741 reverting to the overhead of full forking operation. There is a
9742 hard maximum of 150 server processes compiled in, largely to
9743 avoid forking out of control and dragging the machine down.
9744 (This is arguably too high).
9746 In my server endurance tests, this mechanism did not appear to
9747 impose any significant overhead, even after I forced it to put the
9748 scoreboard file on a normal filesystem (which might have more
9749 overhead than tmpfs). [Robert Thau]
9751 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9754 *) Read .htaccess files even in directory with <Directory> section.
9755 (Former incompatibility noted on mailing list, now fixed). [Robert
9758 *) "HEAD /" gives the client a "Bad Request" error message, rather
9759 than trying to send no body *and* no headers. [Cliff Skolnick].
9761 *) Don't produce double error reports for some very obscure cases
9762 mainly involving auth configuration (the "all modules decline to
9763 handle" case which is a sure sign of a server bug in most cases,
9764 but also happens when authentication is badly misconfigured).
9767 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9768 it's *for*, and this sort of thing really shouldn't be cluttering
9769 up the Makefile). [Robert Thau]
9771 *) Incidental code cleanups in http_main.c --- stop dragging
9772 sa_client around; just declare it where used. [Robert Thau]
9774 *) Another acc-related fix. (It doesn't like const char
9775 in some places...). [Mark Cox]
9777 Changes with Shambhala 0.6.1 13 Jul 1995
9779 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9780 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9782 *) Compiles clean with acc on SunOS [Paul Sutton]
9784 *) Reordered modules in modules.c so that Redirect takes priority
9785 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9786 believe it or not, he has an actual site with a ScriptAlias and
9787 a Redirect declared for the *exact same directory*. Even *my*
9788 compatibility fetish wouldn't motivate me to fix this if the fix
9789 required any effort, but it doesn't, so what the hey.
9791 *) Fixed to properly default several server_rec fields for virtual
9792 servers from the corresponding fields in the main server_rec.
9793 [Cliff Skolnick --- 'port' was a particular irritant].
9795 *) No longer kills off nph- child processes before they are
9796 finished sending output. [Matthew Gray]
9798 Changes with Shambhala 0.6.0 10 Jul 1995
9800 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9801 the connection to the client in an "aborted" state, but otherwise
9802 allow whatever handlers are running to clean up. hard_timeout()s
9803 abort the request in progress completely; anything not tied to some
9804 resource pool cleanup will leak. They're still around because I
9805 haven't yet come up with a more elegant way of handling
9806 timeouts when talking to something that isn't the client. The
9807 default_handler and the dir_handler now use soft timeouts, largely
9808 so I can test the feature. [Robert Thau]
9810 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9811 the case of log handlers dying prematurely is probably handled VERY
9812 gracelessly at this point, and if the logger stops reading input,
9813 the server will hang. (It is known to correctly restart the
9814 logging process on server restart; this is (should be!) going through
9815 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9816 script). [Robert Thau]
9818 *) asis files supported (new module). [Robert Thau]
9820 *) IdentityCheck code is compiled in, but has not been tested. (I
9821 don't know anyone who runs identd). [Robert Thau]
9823 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9824 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9826 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9828 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9829 as timeouts are not in scope. [Robert Thau]
9831 *) quoted-string args in config files now handled correctly (doesn't drop
9832 the last character). [Robert Thau; reported by Randy Terbush]
9834 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9835 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9837 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9838 default default type); the former default default behavior when all
9839 type-checkers defaulted had been a core dump. [Paul Sutton]
9841 *) Copy filenames out of the struct dirent when indexing
9842 directories. (On Linux, readdir() returns a pointer to the same
9843 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9845 Changes with Shambhala 0.5.3 [not released]
9847 *) Default response handler notes "file not found" in the error log,
9848 if the file was not found. [Cliff Skolnick].
9850 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9851 code no longer sets up bogus PATH_INFO which fakes out the directory
9852 handler). [Cliff Skolnick]
9854 Changes with Shambhala 0.5.2 06 Jul 1995
9856 *) Changes to http_main.c --- root server no longer plays silly
9857 games with SIGCHLD, and so now detects and replaces dying
9858 children. Child processes just die on SIGTERM, without taking
9859 the whole process group with them. Potential problem --- if any
9860 child process refuses to die, we hang in restart.
9861 MaxRequestsPerChild may still not work, but it certainly works
9862 better than it did before this! [Robert Thau]
9864 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9865 work (or work better, at least); over-long description lines
9866 properly terminated. [Mark Cox]
9868 *) http_request.c now calls unescape_url() more places where it
9869 should [Paul Sutton].
9871 *) More directory handling bugs (reported by Cox)
9872 Parent Directory link is now set correctly. [Robert Thau]
9874 Changes with Shambhala 0.5.1 04 Jul 1995
9876 *) Generalized cleanup interface in alloc.c --- any function can be
9877 registered with alloc.c as a cleanup for a resource pool;
9878 tracking of files and file descriptors has been reimplemented in
9879 terms of this interface, so I can give it some sort of a test.
9882 *) More changes in alloc.c --- new cleanup_for_exec() function,
9883 which tracks down and closes all file descriptors which have been
9884 registered with the alloc.c machinery before the server exec()s a
9885 child process for CGI or <!--#exec-->. CGI children now get
9886 started with exactly three file descriptors open. Hopefully,
9887 this cures the problem Rob H. was having with overly persistent
9888 CGI connections. [Robert Thau]
9890 *) Mutual exclusion around the accept() in child_main() --- this is
9891 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9892 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9893 This uses fcntl(F_SETLK,...) on the error log descriptor because
9894 flock() on that descriptor won't work on systems which have BSD
9895 flock() semantics, including (I think) Linux 1.3 and Solaris.
9897 This does work on SunOS (when the server is idle, only one
9898 process in the pool is waiting on accept()); it *ought* to work
9899 on the other systems. [Robert Thau]
9901 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9903 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9905 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9907 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9908 be unnecessary if I go to the revised timeout-handling scheme).
9911 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9912 string) even if none came in with the request. [Robert Thau]
9914 *) CHANGES file added to distribution ;-).
9916 Changes with Shambhala 0.4.5
9918 *) mod_dld --- early dynamic loading support [rst]
9919 *) Add wildcard content handlers for XBITHACK; default_hander now
9920 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9921 *) XBITHACK supported as a wildcard content-handler, and
9922 configurable at run-time (not just at compile time, as in the
9923 "patchy server" releases) [rst]
9925 Changes with Shambhala 0.4.4 30 Jun 1995
9927 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9928 *) Handle Addtype x/y .z [rst, reported by Cox]
9930 Changes with Shambhala 0.4.3
9932 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9933 synonymous [rst, terbush]
9935 Changes with Shambhala 0.4.1 28 Jun 1995
9937 *) First-cut virtual host implementation; some refit in the config
9938 reading code, and log management, was necessary to support this [rst]
9939 *) Sub-pool machinery, originally added to avoid excessive storage
9940 allocation on listings of large directories (which turned out to
9941 be the problem that the 0.3 storage accounting was added to
9942 find). Subrequests and mod_dir changed to use subpools. [rst]
9943 *) More memory debugging --- free list consistency checks. [rst]
9944 *) Added err_headers to request_rec, with support elsewhere [rst]
9945 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9947 Changes with Shambhala 0.3 19 Jun 1995
9949 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9950 *) Don't compile in mod_ai_backcompat by default
9951 *) Switch name of server from Apache to Shambhala in Makefile
9952 *) Add some accounting routines to track memory usage in the pools,
9955 Changes with Shambhala 0.2
9957 *) Set DOCUMENT_ROOT CGI variable
9958 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9959 *) Add critical section protection to handling of cleanup structures
9961 *) Significant code reorg within the server core to group related
9962 functions together [rst]
9963 *) Correctly handle clients that hang up before sending any request
9965 *) Replace dying child processes. [rst]
9967 Changes with Shambhala 0.1 12 Jun 1995
9969 Major rewrite of the pre-existing "patchy server" codebase, by
9970 Robert Thau (rst). Significant portions of the server code, such
9971 as configuration-file handling and HTTP authentication support,
9972 were ripped out and rewritten from scratch. Code that was not
9973 completely rewritten was significantly altered.
9975 Major changes with this release include:
9977 *) Introduction of the module API; in request handling, the central
9978 machinery just dispatches to various modules, which actually do
9979 most of the work. Configuration handling is similar --- modules
9980 declare their own commands, and the central machinery just
9983 API features from shambhala/0.1 were substantially unchanged in
9984 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9985 release, such as wildcard handlers and subpools, were added in
9986 subsequent Shambhala releases, and were also generally rst's
9989 *) This release included the following modules:
9991 mod_access (access control --- allow and deny directives),
9992 mod_alias (Alias and Redirect commands),
9993 mod_auth (straight HTTP authentication, based on flat-files)
9994 mod_auth_dbm (same, with dbm files)
9995 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9996 mod_common_log (CLF access logs; later renamed mod_log_common)
9997 mod_dir (directory indexing)
9998 mod_include (server-side includes)
9999 mod_mime (AddType directives)
10000 mod_negotiation (content negotiation)
10001 mod_userdir (support for users' public_html directories)
10003 It also included a mod_ai_backcompat, which was a private hack
10004 for back-compatibility with rst's own AI-lab servers.
10006 All of these modules were substantially complete, and functional
10007 or nearly so (a few, which implemented features not in use at
10008 Thau's site, required patches of a few lines).
10010 *) sub-request machinery, to allow modules to determine how other
10011 modules would assign MIME types to a given file, or optionally
10012 serve its content (this is heavily used by mod_dir, mod_include
10013 and mod_negotiation).
10015 *) Resource pool system for keeping track of memory allocated and
10016 files opened in service of a particular request. Much of the
10017 code in the modules (when they weren't rewrites) was adjusted to
10018 replace a pervasive convention of using fixed-size buffers on
10019 the stack with an equally pervasive convention of using memory
10020 allocated with palloc().
10022 *) Reorganization of data structures associated with a given
10023 request to eliminate use of global variables and the troublesome
10024 unmunge_name function (used in NCSA and early Apache releases to
10025 attempt to determine the URI which mapped to a given filename
10026 --- a difficult proposition, given that it is easy to produce
10027 setups in which multiple URIs map to the same file).
10029 *) Source files renamed and rearranged
10031 *) Very simple pre-forking behavior --- parent process forked off a
10032 fixed number of children, and then just waited for SIGHUP.
10034 *) Other more minor changes too numerous to list.
10036 This release included modified versions of a lot of code from the
10037 Apache 0.6.4 public release, plus an early pre-forking patch
10038 codeveloped by Robert Thau and Rob Hartill.
10040 Changes with Apache 0.7.3 20 Jun 1995
10042 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10043 were incorporated by Rob Hartill on the main branch while Robert Thau
10044 worked on the Shambhala rewrite above. Most were merged into the
10045 Shambala architecture after Apache 0.8.0.
10047 Changes with Apache 0.6.4 13 May 1995
10049 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10052 Changes with Apache 0.5.1 10 Apr 1995
10054 Changes with Apache 0.4 02 Apr 1995
10056 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10059 Changes with Apache 0.3 24 Mar 1995
10061 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10064 Changes with Apache 0.2 18 Mar 1995
10066 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10067 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10068 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
