1 Changes with Apache 2.0.24-dev
3 *) Fix a problem with the new method code. We need to cast
4 the 1 to an apr_int64_t or it will be treated as a 32-bit
5 integer, and it will wrap after being shifted 32 times.
6 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
8 *) Fix a bug in mod_expires. Previous to this patch, if you
9 told mod_expires to add 604800 seconds to the last-modified
10 time, it actually added 604800 usec's to the last-modified time,
11 so that when looking at the response it looked like nothing
12 had been done. The root of the problem was that we always compute
13 time in usec's, but we ask users to input sec's. This means we
14 need to convert to usec's before using those values.
17 *) The worker MPM now handles shutdown and restart requests. It
18 definately isn't perfect, but we do stop the servers correctly.
19 The biggest problem right now is that SIGHUP causes the server to
20 just die. [Ryan Bloom]
22 Changes with Apache 2.0.23
24 *) Use the prefork MPM by default on Unix. [various]
26 *) mod_rewrite: Fix the line ending on some non-Unix systems for
27 messages written to the rewrite log.
28 [Richard Labennett <rlabenn@us.ibm.com>]
30 *) All mod_autoindex query parsing is now quietly quashed with the
31 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
32 still drops the column sort <a href>'s for the column headers, but
33 IgnoreClient is required to ignore these Query options entirely.
36 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
37 to allow the client to select plain, FancyIndexing or HTMLTable
38 formatting, V=[0|1] to inhibit or enable version sorting, and
39 P=pattern to return only specific files. The old Query Arguments
40 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
41 as before), and O=A|D for ordering ascending or descending.
44 *) Fixed an error in mod_include's directive parsing routines which
45 caused #if, #elif, and #else expressions containing backslashes
46 to be improperly evaluated. [Cliff Woolley]
48 *) Introduced new mod_autoindex IndexOptions flags; SuppressIcon to
49 drop the icon column, SuppressRules to drop the <hr> elements,
50 and HTMLTable to create rudimentary HTML table listings (implies
51 FancyIndexing). [William Rowe]
53 *) Re-Introduced the mod_autoindex IndexOptions flag TrackModified
54 from Apache 1.3.15. This is needed for two reasons, first, given
55 multiple machines within a server farm, ETags and Last-Modified
56 stamps won't correspond from machine to machine, and second, many
57 Unixes don't capture changes to the date or time stamp of existing
58 files, since these don't modify the dirent itself. [William Rowe]
60 *) Re-Introduced the mod_autoindex InextOptions flag FoldersFirst
61 and DirectoryWidth options from Apache 1.3.10.
62 [William Rowe, Ken Coar]
64 *) Eliminated FancyIndexing directive, depricated early in Apache
65 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
67 *) mod_autoindex now excludes any file names that would result in
68 an error, other than a success or redirect. Also optimized
69 the parent directory, always included except in the URI '/'.
72 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
73 negotiated index pages, and prevent the server from defaulting
74 to an autoindex of the directory. mod_negotiation will now die
75 with a 500 Internal Error if it could match some filenames
76 (e.g. for mod_dir) but none can be served. mod_negotation now
77 refuses to serve any file with an extention that mod_mime doesn't
78 recognize, and wasn't part of the request. [William Rowe]
80 *) Eliminate mod_cgi's handling of .exe files without the .exe file
81 extension. This is already handled by multiviews, if the admin
82 wishes to AddHandler .exe or define a content type handler and
83 associate .exe files with that content type. Multiviews must be
84 enabled to allow these to be served. [William Rowe]
86 *) Speed up the server's response to a spike in incoming workload
87 or restarts by assigning empty scoreboard slots to new processes
88 when they are available. [Greg Ames]
90 *) Add a handler to mod_includes.c. This handler is designed to
91 implement the XbitHack directive. This can't be done with a
92 fixup, because we need to check the content-type, which is
93 only available in the handler phase. [Ryan Bloom]
95 *) Make the includes filter check return codes from filters lower in
96 the filter chain. If a lower level filter returns an error, then
97 the request needs to stop immediately. This allows mod_include to
98 stop parsing data once a lower filter recognizes an error.
101 *) Add the ability to extend the methods that Apache understands
102 and have those methods <limit>able in the httpd.conf. It uses
103 the same bit mask/shifted offset as the original HTTP methods
104 such as M_GET or M_POST, but expands the total bits from an int to
105 an ap_int64_t to handle more bits for new request methods than
106 an int provides. [Cody Sherr <csherr@covalent.net>]
108 *) Fix broken mod_mime behavior in merging its arguments. Possible
109 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
111 *) Solve many mod_ssl porting issues (too many to detail) with
112 help from the whole team, but most notably [Ralf S. Engelschall,
113 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
114 Doug MacEachern, William Rowe, Cliff Woolley]
116 *) More stall fixes for the threaded & worker mpm's.
117 Make mod_status output more accurate. Don't
118 count workers in processes which aren't actively
119 serving requests. [Greg Ames]
121 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
123 *) Add a single listener/multiple worker MPM. This MPM is
124 definately not fully correct, but it allows us to solve many
125 of the problems that exist in the threaded MPM. This is a
126 modified version of the threaded MPM. [Ryan Bloom]
128 *) Improve content generation throughout Apache, providing closer
129 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
130 Transitional specifications. [William Rowe]
132 Changes with Apache 2.0.22
134 *) Fix a problem where the threaded MPM stalls after restarts or
135 segfaults. Also prevent multiple active processes from using
136 the same scoreboard slot. [Greg Ames]
138 *) Apache/Win32 now fills in the service description with Apache's
139 server version string, including loaded and advertised modules.
142 *) Improved support for the Win32 build, to recover gracefully from
143 missing apr or apr-util directories or the awk interpreter,
144 create the proper cgi-bin examples, including a test-cgi.bat, and
145 fix the perl shebang line for printenv.pl, when installing from
146 the build environment. [William Rowe]
148 *) Fix a segfault in threaded.c caused by passing uninitialized
149 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
151 *) Use new APR number conversion functions to reduce CPU consumption
152 when setting the content length, and in mod_log_config.
155 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
156 where HEAD response headers were being repeated twice for
157 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
158 problem in the http_header filter was exposed by the recent rewrite
159 of the content_length filter. [Taketo Kabe, Bill Stoddard]
161 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
162 restarts. A garbage pointer to a vhost's server_rec from the
163 previous generation was being left around under certain
164 conditions. [Greg Ames]
166 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
167 used to appear as '(none', without the closing paren.
168 [Günter Knauf <eflash@gmx.net>]
170 *) Improve the exports generating awk script. In the past, we had
171 work around problems in the awk script by avoiding some #if and
172 #ifdefs. This has bitten us many times in generating the exports.c
173 file. This improvement allows corrects the header file parsing.
174 [Sander Striker <striker@apache.org>]
176 Changes with Apache 2.0.21
178 *) Resolve the Win32 htpasswd bug, where a file that existed would be
179 overwritten, regardless of the -c flag.
180 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
182 *) Introduce connection sub-pools into ab. Truncating the lifetime
183 of these allocations means that ab no longer perpetually grows
184 its working set, running out of memory on large request attempts.
187 *) Make scoreboard creation a hook. This allows management
188 modules to have access to the scoreboard at the time that it is
189 created, and at every restart request.
190 [Cody Sherr <csherr@covalent.net>]
192 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
193 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
194 daemon index actually used in the scoreboard. I also
195 updated the pertinent calls. [Paul J. Reder]
197 *) Win32: Prevent listening sockets from being inherited by
198 the Apache child process, CGI scripts, rotatelog process
199 etc. If the Apache child process segfaults, any processes
200 that the child started are not reaped. Prior to this fix,
201 these processes inherited the listening sockets which sometimes
202 prevented the restarted Apache child process from accepting
203 connections (ie, the server would hang).
206 *) Provide vhost and request strings when ExtendedStatus is on.
209 *) Fix some issues with the pod and prefork: check the pod *after*
210 processing a connection so that a server processing a time-
211 consuming request bails out as soon as practical; when the
212 parent process wakes up a server process via connect(), use an
213 APR timeout on the connect() so that we don't hang for a long
214 time if there aren't server processes around to do accept().
215 [Jeff Trawick, Greg Ames]
217 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
218 spends a lot of time in apr_table_get calls. Using the default
219 httpd.conf, the tables for languages and charsets are somewhat
220 large, so the time spent scanning them on each request is
221 significant. Replacing the tables with hash tables provides
222 a nice speedup. [Brian Pane <bpane@pacbell.net>]
224 *) Add two functions to allow modules to access random parts of the
225 scoreboard. This allows modules compiled for one MPM to access the
226 scoreboard, even if it the server was compiled for another MPM.
227 [Harrie Hazewinkel <harrie@covalent.net>]
229 Changes with Apache 2.0.20
231 *) Fix problem in content-length filter where the filter would
232 buffer all the output from a CGI before sending any bytes
233 down the filter stack to the network. This problem would cause
234 significant memory consumption if the CGIs generated
235 lots of bytes. [Bill Stoddard]
237 *) Get non-blocking CGI pipe reads working with the bucket brigades.
240 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
243 *) Fix a bug in the threaded MPM that would cause it to kill off all
244 workers immediately after starting if the number of workers started
245 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
247 Changes with Apache 2.0.19
249 *) Fix problem with threaded MPM. The problem was that if each child
250 process was busy serving a single long-lived request and the server
251 was sent a graceful restart signal, the server would stop serving
252 requests. This would happen because each child process would wait to
253 die until the last thread was done, and the parent wouldn't spawn any
254 new children until a process died. Now, the parent looks at the fact
255 that the children are dying gracefully, and starts new children.
256 Those new children only start enough threads to compliment the number
257 of threads in the other child process that shares the same spot in
258 the scoreboard. In this way, we make sure to never go over
259 MaxClients. [Ryan Bloom]
261 *) modified mod_negotiation and mod_autoindex to speed up by almost a
262 factor of two on apr_dir_read()-enhanced platforms, such as Win32
263 and OS2, by calling ap_sub_request_lookup_dirent() with the results
264 already provided by apr_dir_read(). [William Rowe]
266 *) mod_file_cache is now more robust to filtering and serves requests
267 slightly more efficiently. [Cliff Woolley]
269 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
270 Module was calling ap_rwrite() followed by ap_rflush() but the
271 served content was not being displayed in the browser. Inspection
272 of the output stream revealed that the first data chunk was
273 missing the trailing CRLF required by the RFC. [Bill Stoddard]
275 *) apxs no longer generates ap_send_http_header() in the example handler
277 *) Fix an ab problem which could cause a divide-by-zero exception
278 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
279 [Ian Holsman <ianh@cnet.com>]
281 *) Solve case-insensitive platforms' confusion about negotiated
282 filenames, allowing files of differnt case to match in choosing
283 the document to serve. [William Rowe]
285 *) Fix brokenness when ThreadsPerChild is higher than the built-in
286 limit. We left ap_threads_per_child at the higher value which
287 led to segfaults when doing certain scoreboard operations.
290 *) Fix seg faults and/or missing output from mod_include. The
291 default_handler was using the subrequest pool for files and
292 MMAPs, even though the associated APR structures typically
293 live longer than the subrequest. [Greg Ames]
295 *) Extend mod_setenvif to support specifying regular expressions
296 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
297 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
298 will cause HAVE_TS to be set if any of the request headers begins
299 with "TS" and has a value that begins with any character in the
300 set [a-z]. [Bill Stoddard]
302 *) httpd children now re-bind themselves to a random CPU on
303 multiprocessor systems on AIX via bindprocessor() in 2.0.
304 [Victor J. Orlikowski]
306 *) Fix htdigest. It would go into a loop in getline when adding
307 a second user. [Bill Stoddard]
309 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
311 *) Automatically generate httpd.exp for AIX.
312 DSOs now work again on AIX in 2.0
313 [Victor J. Orlikowski]
315 *) Add a new request hook, error_log. This phase allows modules
316 to act on the error log string _after_ it has been written
317 to the error log. The goal for this hook is to allow monitoring
318 modules to send the error string to the monitoring agent.
321 *) Modify mod_echo to make it use filters for input and output.
322 [Ryan Morgan <rmorgan@covalent.net>]
324 *) Extend mod_headers to support conditional driven Header
325 add, append and set. Use SetEnvIf to set an envar and conditionally
326 add/append/set headers based on this envar thusly:
328 SetEnvIf TSMyHeader value HAVE_TSMyHeader
329 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
331 If the request contains header "TSMyHeader: value" then header
332 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
335 *) Extend mod_headers to support using format specifiers on Header
336 add, append and set header values. Two format specifiers are supported:
338 %t - reports, in UTC microseconds since the epoch, when the
339 request was received.
341 %D - reports the time, in microseconds, between when the request was
342 received and the response sent.
345 Header add MyHeader "This request served in %D microseconds. %t"
347 results in a header being added to the response that looks like this:
349 MyHeader: This request served in D=5438 microseconds. t=991424704447256
353 *) Fix reset_filter(). We need to be careful how we remove filters.
354 If we set r->output_filters to NULL, we also have to reset the
355 connection's filters. [John Sterling]
357 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
359 *) Add a check to ap_die() to make sure the filter stack is sane and
360 contains the correct basic filters when an error occurs. This fixes
361 a problem where headers are not being sent on error. [John Sterling]
363 *) New Header directive 'echo' option. "Header echo regex" will
364 cause any headers received on the request that match regex to be
365 echoed to (included in) the response headers.
368 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
369 This prevented the inclusion of apr_compat.h. PR #7773
370 [Oleg Broytmann <phd@phd.pp.ru>]
372 *) Moved util_uri to the apr-util library. This required a bunch of
373 apr_name changes for the uri utility functions. [Justin Erenkrantz]
375 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
376 insert_filter phase so that other filters are not bypassed by default.
379 *) Reimplement mod_headers as an output filter. mod_headers can now
380 add custom headers to inbound requests using the RequestHeader directive
381 and to responses using the same old Header directive. [Graham Leggett]
383 Changes with Apache 2.0.18
385 *) Fix command-line processing so that if a bad argument is specified
386 Apache will exit. [Jeff Trawick]
388 *) Change the make targets and rules to be consistent in all of the
389 Apache-owned source trees. [Roy Fielding]
391 *) Fix processing of the TRACE method. Previously we passed bogus
392 parms to form_header_field() and it overlaid some vhost structures,
393 resulting in a segfault in check_hostalias().
394 [Greg Ames, Jeff Trawick]
396 *) Win32: Add support for reliable piped logs. If the logging process
397 goes down, Apache will automatically restart it. This function has
398 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
401 *) Do not start piped log processes during the config file
402 preflight. This change also circumvents a problem on
403 Windows where the rotatelog processes created during preflight
404 was not getting cleaned up properly.
407 *) add "Request Phase Participation" info to mod_info
410 *) Make first phase changes to the scoreboard data structures in
411 preparation for the rewriting of the scoreboard per my posted
412 design notes. [Paul J. Reder]
414 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
415 and apr-util, allow it to be overridden by the configure command-line
416 (default="--silent") and introduce LT_LDFLAGS to replace what we were
417 formerly abusing as LTFLAGS. [Roy Fielding]
419 *) Clean up the reporting of incorrect closing container tags.
420 [Barrie Slaymaker <barries@slaysys.com>]
422 *) Simplify the configure process by moving all libtool stuff to APR
423 and moving hints.m4 inline. [Roy Fielding]
425 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
426 of functions used by mod_proxy for export in the DLL
427 [Ian Holsman <IanH@cnet.com>]
429 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
430 request body from its stdin but no reqest body is being written to
431 the cgi. [Jeff Trawick]
433 *) mod_log_config: %c connection status incorrectly logged
434 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
437 *) Get mod_cern_meta working under Windows
440 *) Create Files, and thus MMAPs, out of the request pool, not the
441 connection pool. This solves a small resource leak that had us
442 not closing files until a connection was closed. In order to do
443 this, at the end of the core_output_filter, we loop through the
444 brigade and convert any data we have into a single HEAP bucket
445 that we know will survive clearing the request_rec.
446 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
449 *) Completely revamp configure so that it preserves the standard make
450 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
451 the configure additions to EXTRA_* variables. Also, allow the user
452 to specify NOTEST_* values for all of the above, which eliminates the
453 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
454 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
455 avoid pointless duplications. Fix the order in which flags are given
456 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
457 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
458 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
459 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
461 *) Get mod_tls to compile/work better on Windows. PR #7612
462 [Bernhard Schrenk <b.schrenk@improx.com>]
464 *) Fix shutdown/restart hangs in the threaded MPM.
465 [Jeff Trawick, Greg Ames, Ryan Bloom]
467 *) Removed the keptalive boolean from conn_rec because it is now only
468 used by a single routine and can be replaced by a local variable.
469 [Greg Stein, Ryan Bloom, Roy Fielding]
471 *) Patch prefork to put enough of the signal processing back in so that
472 signals are all handled properly now. The previous patch fixed the
473 deadlock race condition, but broke the user directed signal handling.
474 This fixes it to work the way it did before my previous prefork patch
475 (primarily, SIGTERM is now working).
477 *) Change how input filters decide how much data is returned to the
478 higher filter. We used to use a field in the conn_rec, with this
479 change, we use an argument to ap_get_brigade to determine how much
480 data is retrieved. [Ryan Bloom]
482 *) Fix seg fault at start-up introduced by Ryan's change to enable
483 modules to specify their own logging tags. mod_log_config
484 registers an optional function, ap_register_log_handler().
485 ap_register_log_handler() was being called by http_core before
486 the directive hash table was created. This patch creates the
487 directive hash table before ap_register_log_handler() is
488 registered as an optional function.
489 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
491 *) Add ap_set_int_slot() function
492 [John K. Sterling <sterling@covalent.net>]
494 *) Under certain circumstances, Apache did not supply the
495 right response headers when requiring authentication.
496 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
497 (This is a port of the change that went into Apache 1.3.19.)
499 *) Allow modules to specify their own logging tags. This basically
500 allows a module to tell mod_log_config that when %x is encountered
501 a specific function should be called. Currently, x can be any single
502 character. It may be more useful to make this a string at some point.
505 Changes with Apache 2.0.17
507 *) If a higher-level filter handles the the byterange aspects of a
508 request, then the byterange filter should not try to redo the
509 work. The most common case of this happening, is a byterange
510 request going through the proxy, and the origin server handles
511 the byterange request. The proxy should ignore it.
512 [Graham Leggett <minfrin@sharp.fm>]
514 *) Changed the threaded mpm to have child_main join to each of the
515 worker threads to make sure the kids are all gone before child_main
516 exits after a signal (cleanup from perform_idle_server_maintenance).
517 This is an extension of Ryans recent commit to make the child_main
520 *) Add more options to the ap_mpm_query function. This also allows MPMs to
521 report if their threads are dynamic or static. Finally, this also
522 implements a new API, ap_show_mpm, which returns the MPM that was
523 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
525 *) Do not install the binaries from the support directory twice.
526 [jun-ichiro hagino <itojun@iijlab.net>]
528 *) The ap_f* functions should flush data to the filter that is passed
529 in, not the the filter after the one passed in.
530 [Ryan Morgan <rmorgan@covalent.net>]
532 *) Make ab work again by changing its native types to apr types and formats.
533 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
535 *) Move the byterange filter and all of the supporting functions back
536 to the HTTP module. The byterange filter turned out to be very
537 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
539 *) Make clean, distclean, and extraclean consistently according to the
540 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
542 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
543 This may have been causing problems stopping processes in the threaded
546 *) Fix content-length in mod_negotiation to a long int representation.
549 *) Remove BindAddress from the default config file.
550 [giles@nemeton.com.au]
552 *) Allow module authors to add a module to their Apache build using
553 --with-module, without re-running buildconf. The syntax is:
554 --with-module=module_type:/path/to/module.c
555 The configure script will copy the module.c file to
556 modules/module_type, and it will be added to the relevant Makefiles.
557 currently, this only works for static modules. [Ryan Bloom]
559 *) Changes required to make prefork clean up idle children properly.
560 There was a window during which a starting worker deadlocks when
561 an idle cleanup arrives before it completes init. Apache then keeps
562 trying to cleanup the same deadlocked worker forever (until higher
563 pids come along, but it still will never reduce below the deadlocked
564 pid). Thus the number of children would not reduce to the correct
565 idle level. [Paul J. Reder]
567 Changes with Apache 2.0.16
569 *) Change the default installation directory to /usr/local/apache2,
570 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
572 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
575 *) Get MaxRequestsPerChild working with the Windows MPM.
578 *) Make generic hooks to work, with mod_generic_hook_import/export
579 experimental modules. [Ben Laurie, Will Rowe]
581 *) Fix segfaults for configuration file syntax errors such as
582 "<Directory>" followed by "</Directory" and
583 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
585 *) Cleanup the --enable-layout option of configure. This makes
586 us use a consistent location for the config.layout file, and it
587 makes configure more portable.
588 [jun-ichiro hagino <itojun@iijlab.net>]
590 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
591 csv/gnuplot format, rudimentary ssl support and various other tweaks
592 to make results more true to what is measured. The upshot of this it
593 turns out that 'ab' has often underreported the true performance of
594 apache. Often by a order of magnitude :-) See talk/paper of Sander
595 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
596 [Dirk-Willem van Gulik]
598 *) Clean up mod_cgid's temporary request pool. Besides fixing a
599 storage leak this ensures that some unnecessary pipes are closed.
602 *) Performance: Add quick_handler hook. This hook is called at the
603 very beginning of the request processing before location_walk,
604 translate_name, etc. This hook is useful for URI keyed content
605 caches like Mike Abbott's Quick Shortcut Cache.
608 *) top_module global variable renamed to ap_top_module [Perl]
610 *) Move ap_set_last_modified to the core. This is a potentially
611 controversial change, because this is kind of HTTP specific. However
612 many protocols should be able to take advantage of this kind of
613 information. I expect that headers will need one more layer of
614 indirection for multi-protocol work, but this is a small step in
615 the right direction. [Ryan Bloom]
617 *) Enable mod_status by default. This matches what Apache 1.3 does.
620 *) Add a ScriptSock directive to the default config file. This is
621 only enabled when mod_cgid is used.
622 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
624 Changes with Apache 2.0.15
626 *) Untangled the buildconf script and eliminated the need for build's
627 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
628 libtool muck that is now under srclib/apr/build. [Roy Fielding]
630 *) Win32: Don't accept more connections than we have worker threads
634 *) Fix bug in the Unix threaded.c MPM that allowed child processes
635 to fork() new child processes.
638 *) Fix a major security problem with double-reverse lookup checking.
639 Previously, a client connecting over IPv4 would not be matched
640 properly when the server had an IPv6 listening socket. PR #7407
641 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
643 *) Change the way the beos MPM handles polling to allow it to stop and
644 restart. Problem was the sockets being polled were being reset by
645 the select call, so once it had accepted a connection it was no
646 longer listening on the UDP socket we use for shutdown instructions.
647 APR needs to be altered, patch on it's way. [David Reid]
649 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
650 on error exit from ap_getline(). Some other code got upset because
651 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
653 *) Handle ap_discard_request_body() being called more than once.
654 [Greg Ames, Jeff Trawick]
656 *) Get rid of an inadvertent close of file descriptor 2 in
657 mod_mime_magic. [Greg Ames, Jeff Trawick]
659 *) Add a hook, create_request. This hook allows modules to modify
660 a request while it is being created. This hook is called for all
661 request_rec's, main request, sub request, and internal redirect.
662 When this hook is called, the the r->main, r->prev, r->next
663 pointers have been set, so modules can determine what kind of
664 request this is. [Ryan Bloom]
666 *) Cleanup the build process a bit more. The Apache configure
667 script no longer creates its own helper scripts, it just
669 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
671 *) Stop the forced downgrade of the connection to HTTP/1.0 for
672 proxy requests. [Graham Leggett]
674 *) Avoid using sscanf to determine the HTTP protocol number in
675 the common case because sscanf is a performance hog. From
676 Mike Abbot's Accelerating Apache patch number 6.
677 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
679 *) Fix a security exposure in mod_access. Previously when IPv6
680 listening sockets were used, allow/deny-from-IPv4-address rules
681 were not evaluated properly (PR #7407). Also, add the ability to
682 specify IPv6 address strings with optional prefix length on Allow
683 and Deny. [Jeff Trawick]
685 *) Enhance rotatelogs so that a UTC offset can be specified, and
686 the logfile name can be formatted using strftime(3). (Brought
687 forward from 1.3.) [Ken Coar]
689 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
690 DuplicateHandle on an IOCompletionPort (a practice which
691 MS "discourages"). The new model does not rely on associating
692 the completion port with the listening sockets, thus the
693 completion port can be completely managed within the child
694 process. A dedicated thread accepts connections off the network,
695 then calls PostQueuedCompletionStatus() to wake up worker
696 threads blocked on the completion port.
699 *) Bring forward the --suexec-umask option which allows the
700 builder to preset the umask for suexec processes. [Ken Coar]
702 *) Add a -V flag to suexec, which causes it to display the
703 compile-time settings with which it was built. (Only
704 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
706 *) Mod_include should always unset the content-length if the file is
707 going to be passed through send_parsed_content. There is no to
708 determine if the content will change before actually scanning the
709 entire content. It is far safer to just remove the C-L as long
710 as we are scanning it. [Ryan Bloom]
712 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
713 request and not Proxy-Authenticate.
714 [Graham Leggett <minfrin@sharp.fm>]
716 Changes with Apache 2.0.14
718 *) Fix content-length computation. We ONLY compute a content-length if
719 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
720 or we already have all the data. [Ryan Bloom]
722 *) Report unbounded containers in the config file. Previously, a typo
723 in the </container> directive could result in the rest of the config
724 file being silently ignored, with undesired defaults used.
727 *) Make the old_write filter use the ap_f* functions for the buffering.
730 *) Move more code from the http module into the core server. This
731 is core code, basically the default handler, the default input
732 and output filters, and all of the core configuration directives.
733 All of this code is required in order for the server to work, with or
734 without HTTP. The server is closer to working without the HTTP
735 module, although there is still more to do. [Ryan Bloom]
737 *) Fix a number of SGI compile warnings throughout the server. Fix some
738 bad parameters to apr_bucket_read(). Fix a bad statement in
739 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
740 consistently; we were mixing apr_time_t and time_t in invalid ways
741 before. In load_file(), call apr_dso_error() instead of
742 apr_strerror() so that we get a more specific string on some platforms.
743 PR #6980 [Jeff Trawick]
745 *) Allow modules to query the MPM about it's execution profile. This
746 query API can and should be extended in the future, but for now,
747 max_daemons, and threading or forking is a very good start.
748 [Jon Travis <jtravis@covalent.net>]
750 *) Modify mod_include to send blocks of data no larger than 9k.
751 Without this, mod_include will wait until the whole file is parsed,
752 or the first tag is found to send any data to the client.
753 [Paul J. Reder <rederpj@raleigh.ibm.com>]
755 *) Fix mod_info, so that <Directory> and <Location> directives are
756 not displayed twice when displaying the current configuration.
757 [Ryan Morgan <rmorgan@covalent.net>]
759 *) Add config directives to override DEFAULT_ERROR_MSG and
760 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
761 [Dan Rench <drench@xnet.com>]
763 *) Get mod_info building and loading on Win32. [William Rowe]
765 *) Begin to move protocol independant functions out of mod_http. The goal
766 is to have only functions that are HTTP specific in the http directory.
769 Changes with Apache 2.0.13
771 *) Don't assume that there will always be multiple calls to the byterange
772 filter. It is possible that we will need to do byteranges with only
773 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
775 *) Move the error_bucket definition from the http module to the
776 core server. Every protocol will need this ability, not just
779 Changes with Apache 2.0.12
781 *) Modify mod_file_cache to save pre-formatted strings for
782 content-length and last-modified headers for performance.
783 [Mike Abbot <mja@trudge.engr.sgi.com>]
785 *) Namespace protect IOBUFSIZ since it is exposed in the API.
786 [Jon Travis <jtravis@covalent.net>]
788 *) Use "Basic" authentication instead of "basic" in ab, as the spec
789 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
791 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
792 without ever filling it out. This fixes PR 7271.
793 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
794 Cliff Woolley <cliffwoolley@yahoo.com>]
796 *) Add a couple of GCC attribute tags to printf style functions.
797 [Jon Travis <jtravis@covalent.net>]
799 *) Add the correct language tag for interoperation with the Taiwanese
800 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
802 *) Migrate the perchild MPM to use the new apr signal child, and
803 APR thread functions. [Ryan Bloom]
805 *) Close one copy of the CGI's stdout before creating the new process.
806 The CGI will still have stdout, because we have already dup'ed it.
807 This keeps Apache from waiting forever to send the results of a CGI
808 process that has forked a long-lived child process.
809 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
811 *) Remove the rest of the pthreads functions from the threaded MPM.
812 This requires the APR support for a signal thread that was just
815 *) Make mod_dir use a fixup for sending a redirect to the browser.
816 Before this, we were using a handler, which doesn't make much
817 sense, because the handler wasn't generating any data, it would
818 either return a redirect error code, or DECLINED. This fits the
819 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
821 *) Make the threaded MPM use APR threads instead of pthreads.
824 *) Get mod_tls to the point where it actually appears to work in all cases.
827 *) implement --enable-modules and --enable-mods-shared for "all" and
830 *) Move the threaded MPM to use APR locks instead of pthread locks.
833 *) Rename mpmt_pthread to threaded. This is more in line with the
834 fact that mpmt_pthread shouldn't be using pthreads directly, and
835 it is a smaller name that doesn't tie into anything.
838 *) Rename the module structures so that the exported symbol matches
839 the file name, and it is easier to automate the installation
840 process (generating LoadModule directives from the module filenames).
843 *) Remove the coalesce filter. With the ap_f* functions, this filter
844 is no longer needed. [Ryan Bloom]
846 Changes with Apache 2.0.11
848 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
849 added feature of allowing a uid/gid per child process. If no
850 uid/gid is specified, then Perchild behaves exactly like dexter.
853 *) Get perchild building again. [Ryan Bloom]
855 *) Don't disable threads just because we are using the prefork MPM.
856 If somebody wants to compile without threads, they must now add
857 --disable-threads to the configure command line. [Ryan Bloom]
859 *) Begin to move the calls to update_child_status into common code, so
860 that each individual MPM does not need to update the scoreboard itself.
863 *) Allow mod_tls to compile under Unix boxes where openssl has been
864 installed to the system include files.
865 [Gomez Henri <new-httpd@slib.fr>]
867 *) Cleanup the mod_tls configure process. This should remove any need
868 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
869 configure doesn't check that yet. [Ryan Bloom]
871 *) Add a very early prototype of SSL support (in mod_tls.c). It is
872 vital that you read modules/tls/README before attempting to build
875 *) Fix a potential seg fault on all platforms. David Reid fixed this
876 on BEOS, but the problem could happen anywhere, so we don't want
877 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
879 *) Add new LogFormat directive, %D, to log time it takes to serve a
880 request in microseconds. [Bill Stoddard]
882 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
883 SetOutputFilter. This corresponds nicely with the other Set
884 directives, which operate on containers while the Add* directives
885 tend to work directly on extensions. [Ryan Bloom]
887 *) Cleanup the header handling a bit. This uses the apr_brigade_*
888 functions for the buffering so that we don't need to compute
889 the length of the headers before we actually create the header
892 *) Allow filters to buffer data using the ap_f* functions. These have
893 become macros that resolve directly to apr_brigade_*.
896 *) Get the Unix MPM's to do a graceful restart again. If we are going
897 to register a cleanup with ap_cleanup_scoreboard, then we have to
898 kill the cleanup with the same function, and that function can't be
901 *) Install all required header files. Without these, it was not
902 possible to compile some modules outside of the server.
905 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
906 forward from 1.3 to 2.0, we missed a single line, which broke regex
907 aliases. [Ryan Bloom]
909 *) We have a poor abstraction in the protocol. This is a temporary
910 hack to fix the bug, but it will need to be fixed for real. If
911 we find an error while sending out a custom error response, we back
912 up to the first non-OK request and send the data. Then, when we send
913 the EOS from finalize_request_protocol, we go to the last request,
914 to ensure that we aren't sending an EOS to a request that has already
915 received one. Because the data is sent on a different request than
916 the EOS, the error text never gets sent down the filter stack. This
917 fixes the problem by finding the last request, and sending the data
918 with that request. [Ryan Bloom]
920 *) Make the server status page show the correct restart time, and
921 thus the proper uptime. [Ryan Bloom]
923 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
924 should reduce the amount of duplicate code that is required to
925 create CGI processes.
926 [Paul J. Reder <rederpj@raleigh.ibm.com>]
928 *) ap_new_connection() closes the socket and returns NULL if a socket
929 call fails. Usually this is due to a connection which has been
930 reset. [Jeff Trawick]
932 *) Move the Apache version information out of httpd.h and into release.h.
933 This is in preparation for the first tag with the new tag and release
936 *) Begin restructuring scoreboard code to enable adding back in
937 the ability to use IPC other than shared memory.
938 Get mod_status working on Windows again. [Bill Stoddard]
940 *) Make mod_status work with 2.0. This will work for prefork,
941 mpmt_pthread, and dexter. [Ryan Bloom]
943 *) Correct a typo in httpd.conf.
944 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
946 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
948 *) Get the correct IP address if ServerName isn't set and we can't
949 find a fully-qualified domain name at startup.
950 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
952 *) Make mod_cgid work with SuExec. [Ryan Bloom]
954 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
955 'extra' stat's for user/group since they should never occur, and now
956 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
957 volumes. [William Rowe]
959 *) Adopt apr features to simplify mod_includes. This changes the
960 behavior of the USER_NAME variable, unknown uid's are now reported
961 as USER_NAME="<unknown>" rather than the old user#000 result.
962 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
964 *) Adopt apr features for simplifing mod_userdir, and accept the new
965 Win32/OS2 exceptions without hiccuping. [William Rowe]
967 *) Replace configure --with-optim option by using and saving the
968 environment variable OPTIM instead. This is needed because configure
969 options do not support multiple flags separated by spaces.
972 *) Fix some byterange handling. If we get a byte range that looks like
973 "-999999" where that is past the end of the file, we should return
974 a PARTIAL CONTENT status code, and return the whole file as one big
975 byterange. This matches the 1.3 handling now. [Ryan Bloom]
977 *) Make the error bucket a real meta-data bucket. This means that the
978 bucket length is 0, and a read returns NULL data. If one of these
979 buckets is passed down after the headers are sent, this data will
980 just be ignored. [Greg Stein]
982 *) The prefork MPM wasn't killing child processes correctly if a restart
983 signal was received while the process was serving a request. The child
984 process would become the equivalent of a second parent process. If
985 we break out of the accept loop, then we need to do die after cleaning
986 up after ourselves. [Ryan Bloom]
988 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
989 restarts. [Ryan Bloom]
991 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
992 the most optimal APR_FINFO_wanted bits. This spares Win32 from
993 performing very expensive owner, group and permission lookups
994 and allows the server to function until these apr_finfo_t fields
995 are implemented under Win32. [William Rowe]
997 *) Support for typedsafe optional functions - that is functions exported by
998 optional modules, which, therefore, may or may not be present, depending
999 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1000 for sample code. [Ben Laurie]
1002 *) filters can now report an HTTP error to the server. This is done
1003 by sending a brigade where the first bucket is an error_bucket.
1004 This bucket is a simple bucket that stores an HTTP error and
1005 a string. Currently the string is not used, but it may be needed
1006 to output an error log. The http_header_filter will find this
1007 bucket, and output the error text, and then return
1008 AP_FILTER_ERROR, which informs the server that the error web page
1009 has already been sent. [Ryan Bloom]
1011 *) If we get an error, then we should remove all filters except for
1012 those critical to serving a web page. This fixes a bug, where
1013 error pages were going through the byterange filter, even though
1014 that made no sense. [Ryan Bloom]
1016 *) Relax the syntax checking of Host: headers in order to support
1017 iDNS. PR#6635 [Tony Finch]
1019 *) Cleanup the byterange filter to use the apr_brigade_partition
1020 and apr_bucket_copy functions. This removes a lot of very messy
1021 code, and hopefully makes this filter more stable.
1024 *) Remove AddModule and ClearModuleList directives. Both of these
1025 directives were used to ensure that modules could be enabled
1026 in the correct order. That requirement is now gone, because
1027 we use hooks to ensure that modules are in the correct order.
1030 *) When SuExec is specified, we need to add it to the list of
1031 targets to be built. If we don't, then any changes to the
1032 configuration won't affect SuExec, unless 'make suexec' is
1033 specifically run. [Ryan Bloom]
1035 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1036 the APR_XTHREAD argument to open a file for consumption by
1037 parallel threads on win32. [William Rowe]
1039 *) Correct a bug in determining when we follow symlinks. The code
1040 expected a stat -1 result, not an apr_status_t positive error.
1041 Also check if the APR_FINFO_USER fields are valid before we
1042 follow the link. [William Rowe]
1044 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1045 mpm_common.c. These functions are only valid on some platforms,
1046 so they should not be in the main-line code. [Ryan Bloom]
1048 *) Remove ap_chdir_file(). This function is not thread-safe,
1049 and nobody is currently using it. [Ryan Bloom]
1051 *) Do not try to run make depend if there are no .c files in the
1052 current directory, doing so makes `make depend` fail.
1055 *) Update highperformance.conf to work with either prefork or
1056 pthreads mpms. [Greg Ames]
1058 *) Stop checking to see if this is a pipelined request if we know
1059 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1060 This keeps us from making an extra read call when serving a 1.0
1061 request. [Ryan Bloom and Greg Stein]
1063 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1064 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1065 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1067 *) Fix the RFC number mentioned when complaining about a missing
1068 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1070 *) Fix an endless loop in ab which occurred when ab was posting
1071 and the server dropped the connection unexpectedly.
1074 *) Fix a segfault while handling request bodies in ap_http_filter().
1075 This problem has been seen with mod_dav usage as well as with
1076 requests where the body was just being discarded. [Jeff Trawick]
1078 *) Some adjustment on the handling and automatic setting (via
1079 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1080 add the capability to specify flags (NOTEST_CFLAGS and
1081 NOTEST_LDFLAGS) which are used to compile Apache, but
1082 not used during the configuration process. Useful for
1083 flags like "-Werror". [Jim Jagielski]
1085 *) Stop using environment variables to force debug mode or
1086 no detach. We now use the -D command line argument to
1087 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1088 [Greg Stein, Ryan Bloom]
1090 *) Change handlers to use hooks. [Ben Laurie]
1092 *) Stop returning copies of filenames from both apr_file_t and
1093 apr_dir_t. We pstrdup the filenames that we store in the
1094 actual structures, so we don't need to pstrdup the strings again.
1097 *) mod_cgi: Fix some problems where the wrong error value was being
1098 traced. [Jeff Trawick]
1100 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1103 *) Add generic hooks. [Ben Laurie]
1105 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1107 *) Fix a segfault caused by mod_ext_filter when the external filter
1108 program does not exist. [Jeff Trawick]
1110 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1111 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1112 was served through mod_charset_lite (or anything else that would
1113 create a transient bucket in this size range). ap_bucket_make_heap()
1114 silently failed (fixed), transient_setaside() discovered it, but
1115 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1117 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1118 is that some browsers send extra lines at the end of POST requests, and
1119 we don't want to delay sending data back to the user just because the
1120 browser isn't well behaved. [Ryan Bloom]
1122 *) Get SuEXEC working again. We can't send absolute paths to suExec
1123 because it refuses to execute those programs. SuEXEC also wasn't
1124 always recognizing configuration changes made using the autoconf
1127 *) Allow the buildconf process to find the config.m4 files in the correct
1128 order. Basically, we can now name config.m4 files as config\d\d.m4,
1129 and we will sort them correctly when inserting them into the build
1130 process. [Ryan Bloom]
1132 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1133 This also allows mod_cgid to use ap_os_create_priviledged_process,
1134 thus allowing for SuExec execution from mod_cgid. Currently, we do
1135 not support everything that standard SuExec supports, but at least
1136 it works minimally now. [Ryan Bloom]
1138 *) Allow SuExec to be configured from the ./configure command line.
1141 *) Update some of the docs in README and INSTALL to reflect some of
1142 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1144 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1145 need to call sendfile again. This gets us serving large files
1146 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1148 *) Get the support programs building cleanly again.
1149 [Cliff Woolley <cliffwoolley@yahoo.com>]
1151 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1152 current directory logic now backs up over bin/ to determine the
1153 server root from the Apache.exe path.
1155 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1156 loadable modules, dynamic libs are all named libfoo.dll, and the
1157 makefile.win populates the include, lib and libexec directories.
1159 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1160 Apache gets IPv6 listening sockets by default. Additionally, the
1161 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1162 numeric address strings (e.g., "Listen [fe80::1]:8080").
1165 *) Modify the install directory layout. Modules are now installed in
1166 modules/. Shared libraries should be installed in libraries/, but
1167 we don't have any of those on Unix yet. All install directories
1168 are modifyable at configure time. [Ryan Bloom]
1170 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1172 *) Get the functions in server/linked into the server, regardless of
1173 which modules linked into the server. This uses the same hack
1174 for Apache that we use for APR and apr-util to ensure all of the
1175 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1176 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1177 the scripts a bit easier.
1180 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1181 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1183 *) Get all of the auth modules to the point that they will install and
1184 be loadable into the server. Our new build/install mechanism expects
1185 that all modules will have a common name format. The auth modules
1186 didn't use that format, so we didn't install them properly.
1189 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1190 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1192 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1194 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1195 after the end of the response. [Ryan Bloom]
1197 *) Get byterange requests working with responses that do not have a
1198 content-length. Because of the way byterange requests work, we have to
1199 have all of the data before we can actually do the byterange, so we
1200 can compute the content-length in the byterange filter.
1203 *) Get exe CGI's working again on Windows.
1206 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1207 they keep track of whether or not their post config hook has been
1208 called before. Instead of a static variable (which is replaced when
1209 the DSO is loaded a second time), use userdata in the process pool.
1212 Changes with Apache 2.0a9
1214 *) Win32 now requires perl to complete the final install step for users
1215 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1216 and installs the conf, htdocs and htdocs/manual directories.
1219 *) Make mod_include use a hash table to associate directive tags with
1220 functions. This allows modules to implement their own SSI tags easily.
1221 The idea is simple enough, a module can insert it's own tag and function
1222 combination into a hash table provided by mod_include. While mod_include
1223 parses an SSI file, when it encounters a tag in the file, it does a
1224 hash lookup to find the function that implements that tag, and passes
1225 all of the relevant data to the function. That function is then
1226 responsible for processing the tag and handing the remaining data back
1227 to mod_include for further processing.
1228 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1230 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1231 fewer parameters: the local and remote socket addresses were removed
1232 from the parameter list because all required information is available
1233 via the APR socket. [Jeff Trawick]
1235 *) Distribution directory structure reorganized to reflect a
1236 normal source distribution with external install targets.
1239 *) The MPMs that need multiple segments of shared memory now create
1240 two apr_shmem_t variables, one for each shared memory allocation.
1241 the problem is that we can't determine how much memory will be required
1242 for shared memory allocations once we try to allocate more than one
1243 variable. The MM code automatically aligns the shared memory allocations,
1244 so we end up needing to pad the amount of shared memory we want based
1245 on how many variables will be allocated out of the shared memory segment.
1246 It is just easier to create a second apr_shmem_t variable, and two
1247 shmem memory blocks.
1250 *) Cleanup the export list a bit. This creates a single unified list of
1251 functions exported by APR. The export list is generated at configure
1252 time, and that list is then used to generate the exports.c file.
1253 Because of the way the export list is generated, we only export those
1254 functions that are valid on the platform we are building on.
1257 *) Enable logging the cookie with mod_log_config
1258 [Sander van Zoest <sander@covalent.net>]
1260 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1263 *) Added lib/aputil/ as a placeholder for utility functions which are not
1264 specific to the Apache HTTP Server (but do not make sense with APR).
1265 The first utility is "apu_dbm": a set of functions to work with DBM
1266 files. This first version can be compiled for SDBM or GDBM databases.
1269 *) Complete re-write of mod_include. This makes mod_include a filter that
1270 uses buckets directly. This has now served the FAQ correctly.
1271 [Paul Reder <rederpj@raleigh.ibm.com>]
1273 *) Allow modules to specify the first filter in a sub_request when
1274 making the sub_request. This keeps modules from having to change the
1275 output_filter immediately after creating the sub-request, and therefore
1276 skip the sub_req_output_filter. [Ryan Bloom]
1278 *) Update ab to accept URLs with IPv6 literal address strings (in the
1279 format described in RFC 2732), and to build Host header fields in
1280 the same format. This allows IPv6 literal address strings to be
1281 used with ab. This support has been tested against Apache 1.3 with
1282 the KAME patch, but Apache 2.0 does not yet work with this format
1283 of the Host header field. [Jeff Trawick]
1285 *) Accomodate an out-of-space condition in the piped logs and the
1286 rotatelogs.c code, and no longer churn log processes for this
1287 condition. [Victor J. Orlikowski]
1289 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1292 Changes with Apache 2.0a8
1294 *) Add a directive to mod_mime so that filters can be associated with
1298 *) Get multi-views working again. We were setting the path_info
1299 field incorrectly if we couldn't find the specified file.
1302 *) Fix 304 processing. The core should never try to send the headers
1303 down the filter stack. Always, just setup the table in the request
1304 record, and let the header filter convert it to data that is ready
1308 *) More fixes for the proxy. There are still bugs in the proxy code,
1309 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1313 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1316 *) APR: Add new apr_getopt_long function to handle long options.
1317 [B. W. Fitzpatrick <fitz@red-bean.com>]
1319 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1320 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1321 hostname resolution/address string parsing and building
1322 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1323 of one of the apr_sockaddr_t structures for a socket. Change
1324 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1326 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1327 I have proxied pages with it, cleanup will commence soon.
1330 *) Make the proxy work with filters. This isn't perfect, because we
1331 aren't dealing with the headers properly. [Ryan Bloom]
1333 *) Do not send a content-length iff the C-L is 0 and this is a head
1334 request. [Ryan Bloom]
1336 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1337 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1339 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1341 *) Get the default_handler to stop trying to deal with HEAD requests.
1342 The idea is to let the content-length filter compute the C-L before
1343 we try to send the data. If we can get the C-L correctly, then we
1344 should send it in the HEAD response.
1347 *) The Header filter can now determine if a body should be sent based
1348 on r->header_only. The general idea of this is that if we delay
1349 deciding to send the body, then we might be able to compute the
1350 content-length correctly, which will help caching proxies to cache
1351 our data better. Any handler that doesn't want to try to compute
1352 the content-length can just send an EOS bucket without data and
1353 everything will just work.
1356 *) Add the referer to the error log if one is available.
1357 [Markus Gyger <mgyger@itr.ch>]
1359 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1360 change, the root of the configuration tree has been exposed to modules
1362 [Ryan Morgan <rmorgan@covalent.net>]
1364 *) Get the core_output_filter to use the bucket interface directly.
1365 This keeps us from calling the content-length filter multiple times
1366 for a simple static request.
1369 *) We are sending the content-type correctly now.
1370 [Ryan Bloom and Will Rowe]
1372 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1373 a bogus bytes-sent value when the only thing being sent was trailers
1374 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1376 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1377 hints file to determine which platforms define
1378 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1381 *) APR: add apr_get_home_directory() [Jeff Trawick]
1383 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1385 *) Not all platforms have INADDR_NONE defined by default. Apache
1386 used to make this check and define INADDR_NONE if appropriate,
1387 but APR needs the check too, and I suspect other applications will
1388 as well. APR now defines APR_INADDR_NONE, which is always a valid
1389 value on all platforms.
1390 [Branko Èibej <brane@xbc.nu>]
1392 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1393 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1395 *) Relax the syntax checking of Host: headers in order to support
1396 iDNS. PR#6635 [Tony Finch]
1398 *) When reading from file buckets we convert to an MMAP if it makes
1399 sense. This also simplifies the default handler because the
1400 default handler no longer needs to try to create MMAPs.
1403 *) BUFF has been removed from the main server. The BUFF code will remain
1404 in the code until it has been purged from the proxy module as well.
1407 *) Byteranges have been completely re-written to be a filter. This
1408 has been tested, and I believe it is working correctly, but it could
1409 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1410 the output from 1.3, the only difference being that 1.3 includes
1411 a content-length in the response, and this does not.
1414 *) APR read/write functions and bucket read functions now operate
1415 on unsigned integers, instead of signed ones. It doesn't make
1416 any sense to use signed ints, because we return the error codes,
1417 so if we have an error we should report 0 bytes read or written.
1420 *) Always compute the content length, whether it is sent or not.
1421 The reason for this, is that it allows us to correctly report
1422 the bytes_sent when logging the request. This also simplifies
1423 content-length filter a bit, and fixes the actual byte-reporing
1424 code in mod_log_config.c
1427 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1428 it says, because it was only used by EOS and FLUSH buckets. Since
1429 neither of those are required at the end of a brigade, this was
1430 really signifying FLUSH_THE_DATA, but that can be determined better
1431 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1432 buckets now return a length of 0, which is actually the amount of data
1433 read, so they make more sense.
1436 *) Allow the core_output_filter to save some data past the end of a
1437 request. If we get an EOS bucket, we only send the data if it
1438 makes sense to send it. This allows us to pipeline request
1439 responses. As a part of this, we also need to allocate mmap
1440 buckets out of the connection pool, not the request pool. This
1441 allows the mmap to outlive the request.
1444 *) Make blocking and non-blocking bucket reads work correctly for
1445 sockets and pipes. These are the only bucket types that should
1446 have non-blocking reads, because the other bucket types should
1447 ALWAYS be able to return something immediately.
1450 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1451 server, but use Ctrl+Break to initiate a graceful restart
1452 instead of duplicating behavior. [John Sterling]
1454 *) Patch mod_autoindex to set the Last-Modified header based on
1455 the directory's mtime, and add the ETag header. [William Rowe]
1457 *) Merge the 1.3 patch to add support for logging query string in
1458 such a way that "%m %U%q %H" is the same as "%r".
1461 *) Port three log methods from mod_log_config 1.3 to 2.0:
1462 CLF compliant '-' byte count, method and protocol.
1465 *) Add a new LogFormat directive, %c, that will log connection
1466 status at the end of the response as follows:
1467 'X' - connection aborted before the response completed.
1468 '+' - connection may be kept-alive by the server.
1469 '-' - connection will be closed by the server.
1472 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1473 Unicode file names and paths for Win32, and tag the Content-Type
1474 from mod_autoindex to reflect that charset if the the feature
1475 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1477 *) Compute the content length (and add appropriate header field) for
1478 the response when no content length is available and we can't use
1479 chunked encoding. [Jeff Trawick]
1481 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1482 so that content input filters get dechunked data when using
1483 the default handler. Also removed REQUEST_CHUNKED_PASS.
1486 *) Add mod_ext_filter as an experimental module. This module allows
1487 the administrator to use external programs as filters. Currently,
1488 only filtering of output is supported. [Jeff Trawick]
1490 *) Most Apache functions work on EBCDIC machines again, as protocol
1491 data is now translated (again). [Jeff Trawick]
1493 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1494 the EBCDIC support. They are noops on ASCII machines, so this
1495 type of translation doesn't have to be surrounded by #ifdef
1496 CHARSET_EBCDIC. [Jeff Trawick]
1498 *) Fix mod_include. tag commands work again, and the server will
1499 send the FAQ again. This also allows mod_include to set aside
1500 buckets that include partial buckets.
1501 [Ryan Bloom and David Reid]
1503 *) Add suexec support back. [Manoj Kasichainula]
1505 *) Lingering close now uses the socket directly instead of using
1506 BUFF. This has been tested, but since all we can tell is that it
1507 doesn't fail, this needs to be really hacked on.
1510 *) Allow filters to modify headers and have those headers be sent to
1511 the client. The idea is that we have an http_header filter that
1512 actually sends the headers to the network. This removes the need
1513 for the BUFF to send headers.
1516 *) Charset translation: mod_charset_lite handles translation of
1517 request bodies. Get rid of the xlate version of ap_md5_digest()
1518 since we don't compute digests of filtered (e.g., translated)
1519 response bodies this way anymore. (Note that we don't do it at
1520 all at the present; somebody needs to write a filter to do so.)
1523 *) Input filters and ap_get_brigade() now have a input mode parameter
1524 (blocking, non-blocking, peek) instead of a length parameter.
1527 *) Update the mime.types file to the registered media types as
1528 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1531 *) Namespace protect some macros declared in ap_config.h
1534 *) Support HTTP header line folding with input filtering.
1537 *) Mod_include works again. This should still be re-written, but at
1538 least now we can serve an SHTML page again.
1541 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1542 to both the BUFF and the socket in the conn_rec. Functions that
1543 want to use the BUFF can, functions that want to use the socket,
1544 can. They point to the same place.
1547 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1548 [Tomas "Ögren" <stric@ing.umu.se>]
1550 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1551 associated pool goes away. (APR pipes on OS/2 were already had this
1552 logic.) This resolvs a fatal file descriptor leak with CGIs.
1555 *) The final line of the config file was not being read if there was
1556 no \n at the end of it. This was caused by apr_fgets returning
1557 APR_EOF even though we had read valid data. This is solved by
1558 making cfg_getline check the buff that was returned from apr_fgets.
1559 If apr_fgets return APR_EOF, but there was data in the buf, then we
1560 return the buf, otherwise we return NULL.
1563 *) Piped logs work again in the 2.0 series.
1566 *) Restore functionality broken by the mod_rewrite security fix:
1567 rewrite map lookup keys and default values are now expanded
1568 so that the lookup can depend on the requested URI etc.
1569 PR #6671 [Tony Finch]
1571 *) Tighten up the syntax checking of Host: headers to fix a
1572 security bug in some mass virtual hosting configurations
1573 that can allow a remote attacker to retrieve some files
1574 on the system that should be inaccessible. [Tony Finch]
1576 *) Add a pool bucket type. This bucket is used for data allocated out
1577 of a pool. If the pool is cleaned before the bucket is destroyed, then
1578 the data is converted to a heap bucket, allowing it to survive the
1582 *) Add a flush bucket. This allows modules to signal that the filters
1583 should all flush whatever data they currently have. There is no way
1584 to actually force them to do this, so if a filter ignores this bucket,
1585 that's life, but at least we can try with this.
1588 *) Add an output filter for sub-requests. This filter just strips the
1589 EOS bucket so that we don't confuse the main request's core output
1590 filter by sending multiple EOS buckets. This change also makes sub
1591 requests start to send EOS buckets when they are finished.
1594 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1595 makes ap_bucket_destroy a return void, which is okay because it
1596 used to always return APR_SUCCESS, and nobody ever checked its
1597 return value anyway.
1598 [Cliff Woolley <cliffwoolley@yahoo.com>]
1600 *) Remove the index into the bucket-type table from the buckets
1601 structure. This has now been replaced with a pointer to the
1602 bucket_type. Also add some macros to test the bucket-type.
1605 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1606 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1607 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1608 All _VAR_ flavors changes to _DATA to be absolutely clear.
1611 *) Add support for /, //, //servername and //server/sharename
1612 parsing of <Directory> blocks under Win32 and OS2.
1613 [Tim Costello, William Rowe, Brian Harvard]
1615 *) Remove the function pointers from the ap_bucket type. They have been
1616 replaced with a global table. Modules are allowed to register bucket
1617 types and use then use those buckets.
1620 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1621 once we finish writing the request body to the cgi child process;
1622 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1623 worked without this change (for reasons I don't understand), but large
1624 ones didn't. [Jeff Trawick]
1626 *) Remove file bucket specific information from the ap_bucket type.
1627 This has been moved to a file_bucket specific type that hangs off
1628 the data pointer in the ap_bucket type.
1631 *) Input filtering now has a third argument. This is the amount of data
1632 to read from lower filters. This argument can be -1, 0, or a positive
1633 number. -1 means give me all the data you have, I'll deal with it and
1634 let you know if I need more. 0 means give me one line and one line
1635 only. A positive number means I want no more than this much data.
1637 Currently, only 0 and a positive number are implemented. This allows
1638 us to remove the remaining field from the conn_rec structure, which
1642 *) Big cleanup of the input filtering. The goal is that http_filter
1643 understands two conditions, headers and body. It knows where it is
1644 based on c->remaining. If c->remaining is 0, then we are in headers,
1645 and http_filter returns a line at a time. If it is not 0, then we are
1646 in body, and http_filter returns raw data, but only up to c->remaining
1647 bytes. It can return less, but never more.
1648 [Greg Ames, Ryan Bloom, Jeff Trawick]
1650 *) mod_cgi: Write all of the request body to the child, not just what
1651 the kernel would accept on the first write. [Jeff Trawick]
1653 *) Back out the change that moved the brigade from the core_output_filters
1654 ctx to the conn_rec. Since all requests over a given connection
1655 go through the same core_output_filter, the ctx pointer has the
1659 *) Fix another bug in the send_the_file() read/write loop. A partial
1660 send by apr_send would cause unsent data in the read buffer to
1661 get clobbered. Complete making send_the_file handle partial
1662 writes to the network.
1665 *) Fix a couple of type fixes to allow compilation on AIX again
1666 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1668 *) Fix bug in send_the_file() which causes offset to be ignored
1669 if there are no headers to send.
1672 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1673 filter. Useful for supporting Windows 9* with a binary
1674 compiled on Windows NT.
1677 Changes with Apache 2.0a7
1679 *) Reimplement core_output_filter to buffer/save bucket brigades
1680 across multiple calls to the core_filter. The brigade will be
1681 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1682 thresholds are hit or the EOS bucket is received.
1685 *) Create experimental filter (buffer_filter) that coalesces bytes
1686 into one large buffer before invoking the next filter in the
1687 chain. This filter is particularly useful with the current
1688 implementation of mod_autoindex when it inserted above the
1689 chunk_filter. mod_autoindex generates a lot of brigades that
1690 containing buckets holding just a few bytes each. The
1691 buffer_filter coalesces these buckets into a single large bucket.
1694 *) Add apr_sendfile() support into the core_output_filter.
1697 *) Add apr_sendv() support into the core_output_filter.
1700 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1701 [Mike Abbott <mja@sgi.com>]
1703 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1704 make much sense, because Apache uses buckets instead of BUFFs now.
1707 *) send_the_file now falls back to a read/write loop on platforms that
1708 do not have sendfile.
1709 [Ryan Bloom and Brian Havard]
1711 *) Install apachectl correctly, and substitute the proper values so
1712 that it works again. [Ryan Bloom]
1714 *) Better(??) handle platforms that lack sendfile().
1717 *) APR now has UUID generation/formatting/parsing support.
1720 *) Begin the http_filter. This is an input filter that understands
1721 the absolute basic amount required to parse an HTTP Request. The
1722 goal is to be able to split headers from request body before passing
1723 the data back to the other filters.
1726 *) Bring forward from 1.3.13 the config directory implementation
1729 *) install apxs if it is created
1732 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1733 conversions. [William Rowe]
1735 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1736 ap_add_output_filter(). [Jeff Trawick]
1738 *) Multiple build and configuration fixes
1741 -add datadir and localstatedir substitutions
1743 -fix logfilename misspelling
1744 -fix evaluation of installation dir variables and
1745 -replace $foobar by $(foobar) to be usefull in the makefile
1749 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1750 $CC_FOR_BUILD is still missing
1751 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1752 -add missing "AR=@AR@" to severaly Makefile.in's
1753 -cache result for "struct rlimit"
1754 -compile all helper programs with native and cross compiler
1755 and use the native version to generate header file
1756 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1758 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1760 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1762 *) Fix a bug where a client which only sends \n to delimit header
1763 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1764 message. Start working on ebcdic co-existance with input
1766 [William Rowe, Greg Ames]
1768 *) If mod_so is enabled in the server always create libexec, even
1769 if there are no modules installed in this directory. This is a
1770 requirement for APXS to work correctly.
1773 *) Connection oriented output filters are now stored in the
1774 conn_rec instead of the request_rec. This allows us to add the
1775 output filter in the pre-connection phase instead of the
1776 post_read_request phase, which keeps us from trying to write an
1777 error page before we have a filter to write to the network.
1778 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1780 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1781 mmap can be used across multiple buckets (default_handler with
1782 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1783 the mmap itself can't be associated with the bucket.
1786 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1789 *) Radical surgery to improve mod_isapi support under Win32.
1790 Includes a number of newer ServerSupportFunction calls, support
1791 for ReadClient (in order to retrieve POSTs greater than 48KB),
1792 and general bug fixes to more reliably load ISAPI .dll's and
1793 prevent leaking handle resources. Note: There are still
1794 discrepancies between IIS's and Apache's ServerVariables, and
1795 async calls are still not supported. Additional warnings are
1796 logged to facilitate debugging of unsupported ISAPI calls.
1799 *) Add input filtering to Apache. The basic idea for the input
1800 filters is the same as the ideas for output filters. The biggest
1801 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1802 should be called, and the order of execution for the filter itself is
1803 different. When writing an output filter, a brigade is passed in,
1804 and filters operate directly on that brigade, when done, they call
1805 ap_pass_brigade. Input filters are the exact opposite. Because input
1806 is not a push operation, filters first call ap_get_brigade. When this
1807 function returns, the input filter will be left with a valid brigade.
1808 The input filter should then operate on the brigade, and return.
1811 *) Fix building on BSD/OS using its native make. The build system
1812 falls back to the BSD .include directive on that host platform.
1815 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1816 SHA1 and plaintext password encodings. Make feature tests a
1817 bit more flexible. [William Rowe]
1819 *) Charset translation: mod_charset_lite handles output content
1820 translation in a filter. mod_charset_lite no longer ignores
1821 subrequests. A bunch of cruft related to BUFF's support for
1822 translating request and response bodies was removed.
1825 *) Move the addition of the CORE filter to the post_read_request
1826 hook in http_core.c. This removes the need to add the filter in
1827 multiple places and allows for an SSL module to be added much
1828 simpler. [Ryan Bloom]
1830 *) Fix a security problem that affects certain configurations of
1831 mod_rewrite. If the result of a RewriteRule is a filename that
1832 contains expansion specifiers, especially regexp backreferences
1833 $0..$9 and %0..%9, then it may be possible for an attacker to
1834 access any file on the web server. [Tony Finch]
1836 *) Fix a bug where errors that are detected during early request parsing
1837 don't produce visible HTTP error messages at the browser, because
1838 the core_filter wasn't present. [Greg Ames]
1840 *) Provide apr_socklen_t as a portability aid.
1841 [Victor J. Orlikowski]
1843 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1844 as well as a comment arg to the add, adduser and update cmds.
1845 update allows the user to clear or preserve pw/groups/comment.
1846 Fixed a bug in dbmmanage that prevented the check option from
1847 parsing a password followed by :group... text. Corrected the
1848 seed calcualation for Win32 systems, and added -lsdbm support.
1851 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1854 *) Avoid a segfault when parsing .htaccess files. An
1855 uninitialized tree pointer was passed to ap_build_config().
1858 *) Change the way that inet_addr & inet_network are checked for
1859 in APR's configure process to allow BeOS BONE to correctly
1860 find them. With this change BeOS BONE now builds from source
1861 with no problems. [David Reid]
1863 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1864 the end of the parameters to execve() was stored in the wrong
1865 location, overlaying the storage beyond the newargs[] array and
1866 also passing uninitialized storage to execve(), which would
1867 sometimes fail with EFAULT. [Jeff Trawick]
1869 *) Fix a bug parsing configuration file containers. With a sequence
1870 like this in the config file
1872 <IfModule mod_kilroy.c>
1875 <IfModule mod_lovejoy.c>
1880 the second container would be terminated at the blank line due to
1881 sediment in the buffer from reading the prior </IfModule> and an
1882 error message would be generated for the real </IfModule> for the
1883 second container. Also due to this problem, any two characters
1884 could be used for "</" in the close of a container.
1887 *) ap_add_filter prototype changed to remove the ctx pointer. The
1888 pointer still remains in the filter structure, but it can not be
1889 a part of the ap_add_filter prototype. The reason is that when
1890 the core uses AddFilter to add a filter to the stack it doesn't
1891 know how to allocate the ctx pointer, or even how much memory should
1892 be allocated. The filters will have to be responsible for allocating
1893 the ctx memory when they need it.
1896 *) Add an AddFilter directive. This directive takes a list of filters
1897 that should be activated for the requested resource.
1900 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1901 some other platforms). [Jeff Trawick]
1903 *) Modify mod_include to be a filter. Currently, it has only been tested
1904 on actual files, but it should work for CGI scripts too.
1907 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1908 writes. apr_flush() for Unix: handle interrupted writes.
1911 *) NameVirtualHost can now take "*" as an argument instead of
1912 an IP address. This allows you to create a purely name-based
1913 virtual hosting server that does not have any IP addresses in
1914 the configuration file and which ignores the local address
1915 of any connections. PR #5595, PR #4455 [Tony Finch]
1917 *) Fix some compile warnings in mod_mmap_static.c
1918 [Mike Abbott <mja@sgi.com>]
1920 *) Fix chunking problem with CGI scripts. The general problem was that
1921 the CGI modules were adding an EOS bucket and then the core added an
1922 EOS bucket. The chunking filter finalizes the chunked response when it
1923 encounters an EOS bucket. Because two EOS buckets were sent, we
1924 finalized the response twice. The fix is to make sure we only send one
1925 EOS, by utilizing a flag in the request_rec.
1928 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1929 and Win32. Previously, the first read from an apr_file_t set up via
1930 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1932 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1933 bucket, instead of using BUFF's and ap_r*.
1936 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1937 [Mike Abbott <mja@sgi.com>]
1939 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1940 code to use APR file's directly instead of going through BUFFs.
1943 *) Fix compile break on some platforms for mod_mime_magic.c
1944 [John K. Sterling <sterling@covalent.net>]
1946 *) Fix merging of AddDefaultCharset directive.
1947 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1949 *) Minor revamp of the rlimit sections of code. We now test
1950 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1951 is now "available" even if the platform doesn't support
1952 the rlimit family (it's just a noop though). [Jim Jagielski]
1954 *) Migrate the pre-selection of which MPM to use for specific
1955 platforms to hints.m4, which contains (or should contain)
1956 all platform specific "hints". [Jim Jagielski]
1958 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1961 *) Add tables with non-string/binary values to APR.
1964 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1967 *) Update PCRE to version 3.2. [Ryan Bloom]
1969 *) Change the way buckets' destroy functions are called so that
1970 they can be more directly used when changing the type of a
1971 bucket in place. [Tony Finch]
1973 *) Add generic support for reference-counting the resources used by
1974 buckets, and alter the HEAP and MMAP buckets to use it. Change
1975 the way buckets are initialised to support changing the type of
1976 buckets in place, and use it when setting aside TRANSIENT buckets.
1977 Change the implementation of TRANSIENT buckets so that it can be
1978 mostly shared with IMMORTAL buckets, which are now implemented.
1981 Changes with Apache 2.0a6
1983 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1985 *) Add a chunking filter to Apache. This brings us one step closer
1986 to removing BUFF. [Ryan Bloom]
1988 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1989 added to the stack is the last filter to be called. [Ryan Bloom]
1991 *) Apache 2.0 has been completely documented using Scandoc. The
1992 docs can be generated by running 'make docs'. [Ryan Bloom]
1994 *) Add filtered I/O to Apache. This is based on bucket brigades,
1995 Currently the buckets still use BUFF under the covers, but that
1996 should change quickly. The only currently written filter is the
1997 core filter which just calls ap_bwrite. [The Apache Group]
1999 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2000 built with thread support. [Jeff Trawick]
2002 *) Abort configuration if --with-layout was specified and there's
2003 no layout definition file. [Ken Coar]
2005 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2007 *) Add support for extension methods for the Allow response header
2008 field, and an API routine for accessing r->allowed and the
2009 list of extension methods in a unified manner. [Ken Coar]
2011 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2012 [Rob Simonson <simo@us.ibm.com>]
2014 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2015 APACHE_XLATE builds. [Jeff Trawick]
2017 *) A configuration file parsing problem was fixed. When the
2018 configuration file started with an IfModule/IfDefine container,
2019 only the last statement in the container would be retained.
2022 Changes with Apache 2.0a5
2024 *) Perchild is serving pages after passing them to different child
2025 processes. There are still a lot of bugs, but this does work. I
2026 have made requests against the same installation of Apache, and had
2027 different servers use different user IDs to serve the responses.
2028 This change moves to using socketpair instead of an AF_UNIX socket.
2031 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2032 It can't seem to pass between child processes yet, but I think we
2033 are closer now than before. This moves us back to using Unix
2034 Domain Sockets. [Ryan Bloom]
2036 *) libapr functions and types renamed with apr_ prefix.
2037 #include "apr_compat.h" for 1.3.x backwards compat
2040 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2041 return the right information on the local socket address.
2042 [Gregory Nicholls <gnicholls@level8.com>]
2044 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2045 [Gregory Nicholls <gnicholls@level8.com>]
2047 *) Add an option to not detach from the controlling terminal without
2048 going into single process mode. This allows for much easier
2049 debugging of the process startup code. [Ryan Bloom]
2051 *) ab: don't use perror() to report the failure of an APR function.
2054 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2055 scoreboard on graceful restarts.
2058 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2059 An invalid ap_proc_t was passed to ap_create_process().
2062 *) Allow modules to register filters. Those filters are still
2063 never called, but this is a step in the right direction.
2064 [Ryan Bloom and Greg Stein]
2066 *) Register the mod_cgid daemon process for cleanup so that it is
2067 killed at termination if it does not die when the parent gets
2068 SIGTERM. This change is to fix occasional problems where the
2069 process stays around. Bugs in similar logic in mod_rewrite and
2070 mod_include were also fixed. [Jeff Trawick]
2072 *) Fix a bug in the time handling. Basically, we were imploding a time
2073 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2074 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2075 uses those two fields to adjust the time value. Because of the HTTP
2076 spec, both of those values can be zero'ed out safely. This fixes
2077 the bug correctly. [Ryan Bloom]
2079 *) Fix a couple of place in the Windows code where the wrong error
2080 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2082 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2084 *) Added the APR_EOL_STR macro for platform dependent differences in
2085 logfiles and other raw text (such as all APR files). Fixes logfiles
2086 not terminated with cr/lf sequences in Win32. [William Rowe]
2088 *) Move all strings functions in APR to src/lib/apr/strings and create
2089 apr_strings.h for the prototypes. [Ryan Bloom]
2091 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2092 to repeat the syscall until we stop getting EINTR. I noticed a
2093 related problem at termination (SIGTERM) on FreeBSD when using
2094 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2095 implementation work properly with child init. Previously, ap_lock()
2096 was essentially a no-op because all children were using different
2097 locks and thus nobody ever blocked. [Jeff Trawick]
2099 *) The htdocs/ tree has been moved out of the CVS source tree into
2100 a separate area for easier development. This has NO EFFECT on
2101 end-users or Apache installations. [Ken Coar]
2103 *) Integrate the mod_dav module for WebDAV protocol handling. This
2104 adds the dav and dav_fs modules, the SDBM library, and additional
2105 XML handling utilities. [Greg Stein]
2107 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2110 *) Update the lib/expat-lite/ library (bring forward changes from
2111 the Apache 1.3 repository). [Greg Stein]
2113 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2114 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2116 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2117 machines where sendfile is detected, but nobody has written ap_sendfile.
2118 [Dave Hill <ddhill@zk3.dec.com>]
2120 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2122 *) ab would start up more connections than needed, then quit when the
2123 desired number were finished. Also fixed a logic error involving
2124 ab keepalives. [Victor J. Orlikowski]
2126 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2127 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2128 timeouts (i.e, if a timeout was specified, the pipe reverted to
2129 a full blocking pipe). Now the behaviour is more in line with
2130 Unix non-blocking pipes.
2133 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2134 cache open file handles along with accept socket reuse enables
2135 Apache 2.0 to serve non-keepalive requests for static files at
2136 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2137 and Apache 2.0 will serve almost 1200 rps on my system).
2140 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2141 supports two config directives, mmapfile (same behavious as
2142 mod_mmap_static) and cachefile. Use the cachefile directive
2143 to cache open file handles. This directive only works on systems
2144 that have implemented the ap_sendfile API. cachefile works today
2145 on Windows NT, but has not been tested on any flavors of Unix.
2148 *) Cleanup the configuration. With the last few changes the
2149 configuration process automatically:
2150 inherits information about how to build from APR. Allowing
2151 APR to inform Apache that it should or should not use -ldl
2153 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2154 based on the threading model
2156 Apache calls APR's configure process before finishing it's
2157 configuration processing, allowing for more information flow
2162 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2163 with non-zero argument makes the socket non-blocking. BeOS and
2164 OS/2 already worked this way. [Jeff Trawick]
2166 *) ap_close() now calls ap_flush() for buffered files, so write
2167 operations work a whole lot better on buffered files.
2170 *) Fix error messages issued from MPMs which explain where to change
2171 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2174 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2175 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2176 now the way that the blocking state of a pipe is manipulated.
2177 ap_block_pipe() is gone. [Jeff Trawick]
2179 *) Correct the problem where the only local host name that the IP stack
2180 can discover are 'undotted' private names. If no fully qualified
2181 domain name can be identified, the default ServerName will be set to
2182 the machine's IP address string. A warning is always provided if the
2183 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2185 *) Repair problems with config file processing which caused segfault
2186 at init when virtual hosts were defined and which caused ServerName to
2187 be ignored when there was no valid DNS setup. [Jeff Trawick]
2189 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2191 *) Add ap_sendfile implementation for AIX
2192 [Victor J. Orlikowski]
2194 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2195 apr_network_io.h, and apr_thread_proc.h.
2196 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2198 *) Bring the allocation and pool debugging code back into a working
2199 state. This will need to be tested as so far it's only been used on
2202 *) Change configuration command setup to be properly typesafe when in
2203 maintainer mode. Note that this requires a compiler that can initialise
2204 unions. [Ben Laurie]
2206 *) Turn on buffering for config file reads. Part of this was to
2207 repair buffered I/O support in Unix and implement buffered
2208 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2210 *) Win32: Fix problem where UTC offset was not being set correctly
2211 in the access log. Problem reported on news group by Jerry Baker.
2214 *) Fix segfault when reporting this type of syntax error:
2215 "</container> without matching <container> section", where
2216 container is VirtualHost or Directory or whatever.
2219 *) Prevent the source code for CGIs from being revealed when using
2220 mod_vhost_alias and the CGI directory is under the document root
2221 and a user makes a request like http://www.example.com//cgi-bin/cgi
2222 as reported in <news:960999105.344321@ernani.logica.co.uk>
2225 *) Add support for the new Beos NetwOrking Environment (BONE)
2228 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2229 final input char is incomplete; ap_bwrite_xlate() now handles
2230 incomplete final input chars. [Jeff Trawick]
2232 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2233 that a bhalfduplex call occurs before logging or else DNS and
2234 such can delay the last packet of the response. [Dean Gaudet]
2236 *) Some syscall reduction in APR on unix -- don't seek when setting
2237 up an mmap; and don't fcntl() more than once per socket.
2240 *) When mod_cgid is started as root, the cgi daemon now switches
2241 to the configured User/Group (like other httpd processes)
2242 instead of continuing as root. [Jeff Trawick]
2244 *) The prefork MPM now uses an APR lock for the accept() mutex.
2245 It has not been getting a lock at all recently. httpd -V now
2246 displays APR's selection of the lock mechanism instead of the
2247 symbols previously respected by prefork. [Jeff Trawick]
2249 *) Change the mmap() feature test to check only for existence.
2250 The previous check required features not used by Apache.
2253 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2254 sometimes mangled. The len parm to accept() was not
2255 initialized, leading sometimes to an endless loop of failed
2256 accept() calls on OS/390 and anywhere else that failed the call
2257 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2258 instead of declaring it ourselves to fix a compilation problem
2259 on Solaris. [Jeff Trawick]
2261 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2263 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2265 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2267 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2268 initialization if ALLOC_DEBUG is defined; no known symptom
2269 otherwise. [Jeff Trawick]
2271 *) Fix typo in configure script when checking for mod_so. bash
2272 doesn't seem to have a problem but /bin/sh on Solaris does.
2273 Symptom: "./configure: test: unknown operator =="
2276 *) Rebind the Win32 NT and 9x services control into the MPM.
2277 All console, WinNT SCM and Win9x pseudo-service control code is
2278 now wrapped within the WinNT MPM.
2281 *) Make a copy of getenv("PATH") before storing for later use. Some
2282 getenv() implementations use the same storage for successive calls.
2283 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2285 *) Server Tokens work in 2.0 again. This also propogates the change
2286 to allow just the product name in the server string using
2290 Changes with Apache 2.0a4
2292 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2293 won't need to call it. [Greg Ames, Jeff Trawick]
2295 *) Move pre_config hook call to between configuration read and config
2296 tree walk. This allows all modules to implement pre_config hooks
2297 and know that they will be called at an appropriate time.
2300 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2303 *) Add pre-config hooks back to all modules.
2306 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2307 ContentDigest enabled and we can't/don't mmap the file.
2310 *) We now report the correct line number for syntax errors in config
2311 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2313 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2314 related bugs, and changed shmem/locking to use apr API. Shared-mem
2315 is currently disabled, however, because of problems with graceful
2316 restarts. [Ronald Tschalär]
2318 *) Fix corruption of IFS variable in --with-module= handling.
2319 Depending on the user's shell or customization thereof, there
2320 would be errors generating ap_config_auto.h later in the configure
2321 procedure. [Jeff Trawick]
2323 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2324 isn't used (as in 1.3), except that on Unix it is now logged via
2325 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2326 to the error log. [Greg Ames, Jeff Trawick]
2328 *) Add '-D' argument processing for run time configuration defines.
2331 *) Organize http_main.c as independent code, such that no code or
2332 global data is exported from it. WIN32 will dynamically link it
2333 to the server core, so this will prevent mutual dependency.
2336 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2337 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2340 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2341 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2343 *) Add mod_charset_lite for configuring character set translation.
2346 *) Add '-n' option to htpasswd to make it print its user:pw record
2347 on stdout rather than having to frob a text file. [Ken Coar]
2349 *) Fix saferead. Basically, we flush the output buffer if a read on the
2353 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2354 a conversion is single-byte only. [Jeff Trawick]
2356 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2357 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2360 *) Fix some minor errors where pid was being manipulated as an int
2361 instead of the portable pid_t. [Roy Fielding]
2363 *) Fix some error log prints that were printing the pointer to a
2364 structure rather than the pid within the structure.
2365 [Jeff Trawick, Roy Fielding]
2367 *) ab: Fix a command-line processing bug; track bad headers in
2368 err_response; support reading headers up to 2K.
2369 [Ask Bjoern Hansen <ask@valueclick.com>]
2371 *) Fix ap_resolve_env() so that it handles new function added in a prior
2372 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2373 config file.") as well as the constructs used by mod_rewrite.
2374 [Paul Reder <rederpj@raleigh.ibm.com>]
2376 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2378 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2379 APR to perform translation, instead of accessing the hard-coded tables
2380 in 1.3's ebcdic.c. [Jeff Trawick]
2382 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2385 *) Add the ability to hook into the config file reading phase. Basically
2386 if a directive is specified EXEC_ON_READ, then when that directive is
2387 read from the config file, the assocaited function is executed. This
2388 should only be used for those directives that must muck with HOW the
2389 server INTERPRETS the config. This should not be used for directives
2390 that re-order or replace items in the config tree. Those changes should
2391 be made in the pre-config step.
2394 *) Add mod_example to the build system.
2397 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2398 byte character sets. [Jeff Trawick]
2400 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2401 Kraemer and Oliver Reh originally according to the change log).
2404 *) Fix a couple of problems in RFC1413 support (controlled by the
2405 IdentityCheck directive). Apache did not build the request string
2406 properly and more importantly Apache would loop forever if the
2407 would-be ident server dropped the connection before sending a
2408 properly terminated response. [Jeff Trawick]
2410 *) apxs works in 2.0.
2413 *) Reliable piped logs work in 2.0.
2416 *) Introduce a hash table implementation into APR to be used for
2417 replacing tables and other random data structures in Apache.
2420 *) Add some more error reporting to htpasswd in the case of problems
2421 generating or accessing the temporary file. Also, pass in a
2422 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2423 is defined). [Ken Coar]
2425 *) Configure creates config.nice now containing your configure
2426 options. Syntax: ./config.nice [--more-options]
2429 *) Fix various return code problems in APR on Win32. For most of
2430 these, APR was returning APR_EEXIST instead of GetLastError()/
2431 WSAGetLastError(). [Jeff Trawick]
2433 *) Make piped logs work again in version 2.0
2436 *) Add VPATH support to UNIX build system of Apache and APR.
2439 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2443 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2444 Patch submitted to author.
2447 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2448 /sbin in PATH on FreeBSD (all submitted to rse previously)
2451 *) Fix building Pthread-based MPMs on OpenBSD
2452 [Sascha Schumann] PR#26
2454 *) Fix ap_readdir() problem on systems where d_name[] field in
2455 struct dirent is declared with only one byte. (This problem only
2456 affected multithreaded builds.) This caused a segfault during
2457 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2458 least). [Jeff Trawick]
2460 *) Fix some make-portability problems on at least Tru64, Irix
2462 [Sascha Schumann] PR#18, PR#39
2464 *) Add ap_sigwait() to support old-style sigwait() on systems
2465 like OS/390 and UnixWare.
2468 *) Add POSIX-thread flags for more platforms.
2471 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2472 (on Unix, at least) to handle resolver errors. Fix a bug in
2473 the definition of APR_ENOMEM so that ap_strerror() can spit
2474 out the correct error message for it.
2477 Changes with Apache 2.0a3
2479 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2482 *) API: *HOOK* macros now have an AP_ prefix
2485 *) Win32: Eliminate redundant calls to initialize winsock.
2486 [Tim Costello <timcostello@ozemail.com.au>]
2488 *) Fix bugs initializing ungetchar for pipes.
2489 [Chia-liang Kao <clkao@CirX.ORG>]
2491 *) The ab program in the src/support directory is now portable using
2495 *) Support directory is being compiled when the server is built
2498 *) The configure option --with-program-name has been added to allow
2499 developers to rename the executable at configure time. This also
2500 changes the name of the config files to match the executable's name.
2503 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2504 containing version numbers. [Martin Pool]
2506 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2507 Unix; access_log and error_log now created with these perms; non-
2508 Unix is unaffected [Jeff Trawick]
2510 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2511 Replaced more magic numbers with MD5_DIGESTSIZE.
2512 [William Rowe, Roy Fielding]
2514 *) Win32: Get mod_auth_digest compiling and added to the Windows
2515 build environment. Not tested and I'd be suprised if it
2516 actually works. [Bill Stoddard]
2518 *) Revamp the Win32 make environment. Makefiles have been removed and
2519 Apache.dsw created to bring together all the pieces. Create new file
2520 os/win32/BaseAddr.ref to define module base addresses (to prevent
2521 dll relocation at start-up).
2522 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2524 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2525 of the \015, \012, and \015\012 constants with macros.
2526 [Greg Ames <gregames@us.ibm.com>]
2528 *) Add ap_xlate_open() et al for translation of text between different
2529 character sets. The initial implementation requires iconv().
2532 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2533 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2535 *) CGI output is being timed out now.
2538 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2539 is used by the new apr file. There is no reason to create a new file
2540 with the same lifetime as the original file.
2543 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2544 module base addresses. This will help shooting seg faults
2545 in the field. [William Rowe <wrowe@lnd.com>]
2547 *) Update Apache on Windows documentation. Add new document
2548 describing how to compile Apache on Windows.
2549 [William Rowe <wrowe@lnd.com>]
2551 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2552 microseconds instead of seconds. Some storage leaks and other
2553 minor bugs in related code were fixed. [Jeff Trawick]
2555 *) Win32: First cut at getting mod_isapi working under 2.0
2556 [William Rowe <wrowe@lnd.com>]
2558 *) First stab at getting mod_auth_digest working under 2.0
2559 quick change summary:
2560 - moved the random byte generation (ap_generate_random_bytes) into APR
2561 - now uses ap_time_t
2562 - compiles and runs on linux
2564 [Brian Martin <bmartin@penguincomputing.com>]
2566 *) Win32: Move the space stripping of physical service names
2567 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2568 unresolved symbol. Add dependency checking to the
2569 CreateService call to ensure TCPIP and AFP (winsock) is started
2571 [William Rowe <wrowe@lnd.com>]
2573 *) Win32: Add code to perform latebinding on functions that may
2574 not exist on all levels of Windows where Apache runs. This
2575 is needed to allow Apache to start-up on Win95/98. All calls
2576 to non portable functions should be protected with
2577 ap_oslevel checks to prevent runtime segfaults.
2578 [William Rowe <wrowe@lnd.com>]
2580 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2582 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2584 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2585 This addresses PR 1623. Still need to address timing out runaway
2586 CGI scripts. [Bill Stoddard]
2588 *) Win32: Make ap_stat Windows 95/98 friendly
2589 [William Rowe <wrowe@lnd.com>]
2591 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2592 always fail. Need to initialise the dwOSVersionInfoSize member of the
2593 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2596 The patch also enhances ap_get_oslevel (and the associated enum) to
2597 handle selected service packs for NT4, and adds recognition for
2598 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2599 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2600 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2602 *) Get mod_rewrite building and running, and mod_status building for Win NT
2603 [Allan Edwards <ake@raleigh.ibm.com>]
2605 *) Patch to port mod_auth_db to the 2.0 api and also to support
2606 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2607 2.7.7. It should work with version 1 as well but I haven't tested it.
2608 [Brian Martin <bmartin@penguincomputing.com>]
2610 *) Get APR DSO code working under Windows. Includes cross platform
2612 [Tim.Costello@BTFinancialgroup.com]
2614 *) Fix some of the Windows APR time functions.
2617 *) FAQ changes related to tidying up historical documents on the web site.
2618 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2620 *) Move Windows DSO code into APR.
2623 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2624 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2625 at build time. At this point, the server will not compile on Windows because
2626 of the recent DSO commits. Fixing those next.
2627 [Bill Rowe & Bill Stoddard]
2629 *) Added error checking for file I/O APR routines.
2630 [Jon Travis <jtravis@covalent.net>]
2632 *) APR: Don't use the values of resolver error codes for the
2633 corresponding APR error codes. On Unix and Win32, return the
2634 proper APR error code after a resolver error. [Jeff Trawick]
2636 Changes with Apache 2.0a2
2638 *) Renamed the executable back to httpd on all platforms other
2642 *) Allow BeOS to survive restarts, log properly and a few
2643 small things it had problems with due to the way it setup
2644 users and groups. [David Reid]
2646 *) Get mod_rewrite working with APR locks
2647 [Paul Reder <rederpj@raleigh.ibm.com>]
2649 *) Actually remove the sempahore when the lock cleanup routine
2650 is called on BeOS. [David Reid]
2652 *) Clear hook registrations between reads of the config file.
2653 When DSOs are unloaded and re-loaded the old hook pointers may
2654 no longer be valid. This fix eliminates potential segfaults.
2655 [Allan Edwards <ake@raleigh.ibm.com>]
2657 *) Fix a problem with Sigfunc not being defined or bypassed
2658 if sigaction() wasn't found. [Jim Jagielski]
2660 *) Fix the locking mechanism on BSD variants. They now use fcntl
2661 locks. This allows the server to start and serve pages.
2664 *) First cut at getting the Win32 installer to work
2665 [William Rowe <wrowe@lnd.com>]
2667 *) Get htpasswd compiling under Windows
2668 [William Rowe <wrowe@lnd.com>]
2670 *) Change the log message for a bind() failure to show the
2671 interface and port number. [Jeff Trawick]
2673 *) Import the documentation from 1.3.12 and bring parts of it
2674 up-to-date with respect to the changes that have occurred
2678 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2679 now logged correctly on BeOS.
2682 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2683 Makefile.win includes the same user interface as the old
2685 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2687 *) Win32 exec now uses COMSPEC environment string for command
2688 shell path resolution.
2689 [William Rowe <wrowe@lnd.com>] PR#3715
2691 *) Win32: ap_connect() was not returning correct error condition
2693 [Allen Prescott <allen@clanprescott.com>]
2695 *) Win32: ap_open() was broken on Win9x because an NT-specific
2696 flag was passed to CreateFile. ap_puts() added an unnecessary
2698 [Jeff Trawick <trawick@us.ibm.com>]
2700 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2701 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2702 confusing ee/et name and made all extensions language/dialect
2703 rather than country reflecting. Changed example files to
2704 explicit reflect the ISO charset and added a few common
2705 ones to the example config [dirkx]
2707 *) Extend external module capability. To use this, you call
2708 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2711 *) Backported the various "default charset" fixes from 1.3.12,
2712 including the AddDefaultCharset directive. [Jim Jagielski]
2714 *) Added the capability to do ${ENVVAR} constructs in the
2715 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2716 it does this on a line by line basis; i.e. if the envvar
2717 expands to something with spaces you have to protect it
2718 by adding quotes around it (Unless of course you expect it
2719 to contains more than one argument. Alternatively you
2720 can compile it on a per token basis; which is what people
2721 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2722 hampers fancier hacks.
2723 [Dirk-Willem van Gulik]
2725 *) Changed the 'ErrorDocument' syntax in that it NO longer
2726 supports the asymetric
2728 ErrorDocument 301 "Some message
2730 Note the opening " quote, without a closing quote. It now
2731 has either the following syntaxes
2733 ErrorDocument XXX /local/uri
2734 ErrorDocument XXX http://valid/url
2735 ErrorDocument XXX "Some Message"
2737 The recognition heuristic is: if it has a space it
2738 is a message. If it has no spaces and starts with a /
2739 or is a valid URL then treat it that way. Otherwise it
2740 is assumed to be a message.
2742 This breaks backward compatibility but makes live a hell
2743 of a lot easier for GUI's and config file parsers.
2744 [Dirk-Willem van Gulik]
2746 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2747 syntax into a 'on' or 'off' syntax. As it currently is the
2748 only non nesting token which uses NO_ARGS and thus is an
2749 absolute pain for any config interface automation. This
2750 breaks backward compatibility. [Dirk-Willem van Gulik]
2752 *) Add ability to add external modules to the build process. This is
2753 done with --with-module=/path/to/module. Modules can only be added
2754 as static modules at this point.
2757 Changes with Apache 2.0a1
2759 *) Fix FreeBSD 3.3 core dump.
2760 Basically, ap_initialize() needs to get called before
2761 create_process(), since create_process() passes op_on structure
2762 to semop() to get a lock, but op_on isn't initialized until
2763 ap_initialize() calls setup_lock(). Here is a slight
2764 rearrangement to main() which calls ap_initialize() earlier...
2765 [Jeff Trawick <trawick@us.ibm.com>]
2767 *) Enable Apache to use sendfile/TransmitFile API
2768 [Bill Stoddard, David Reid, Paul Reder]
2770 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2774 *) Make file I/O and network I/O writev/sendv APIs consistent.
2775 Eliminate use of ap_iovec_t and use Posix struct iovec.
2776 Use seperate variable on ap_writev to set the number of iovecs
2777 passed in and number of bytes written.
2780 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2781 with ap_create_file_iol(). ap_create_file_iol() requires that
2782 the file be opened prior to the call using ap_open().
2785 *) Port mod_include and mod_cgi to 2.0
2786 [Paul Reder, Bill Stoddard]
2788 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2789 bytes_read/bytes_written is always valid (never -1). Plus
2790 some fixes to buff.c to correct problems introduced by the
2791 errno => ap_status_t changes a while back. Plus a fix to
2792 chunked encoding introduced right at the beginning of 2.0.
2795 *) Revamped UNIX build system to use autoconf and libtool.
2796 [Manoj Kasichainula, Sascha Schumann]
2798 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2800 *) More rigorous checking of Host: headers to fix security problems
2801 with mass name-based virtual hosting (whether using mod_rewrite
2802 or mod_vhost_alias).
2803 [Ben Hyde, Tony Finch]
2805 *) Add back support for UseCanonicalName in <Directory> containers.
2806 [Manoj Kasichainula]
2808 *) Added APLOG_STARTUP log type. This allows us to write an error
2809 message without any of the date and time information. As a part
2810 of this change, I also removed all of the calls to fprintf(stderr
2811 and replaced them with calls to ap_log_error using APLOG_STARTUP
2812 writing to stderr is no longer portable, because we don't direct
2813 stderr to the error log on all platforms.
2816 *) Convert error logging functions to take errno as an argument.
2817 This makes our error logs more portable, because some Windows API's
2818 don't set errno. This change allows us to still output a valid
2819 message on all of our platforms.
2822 *) mod_mime_magic runs in 2.0-dev now.
2823 [Paul Reder <rederpj@raleigh.ibm.com>]
2825 *) sendfile has been added to APR.
2826 [John Zedlewski <zedlwski@Princeton.EDU>]
2828 *) buff.c has been converted to no longer use errno.
2829 [Manoj Kasichainula]
2831 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2832 interface adaption to APR functions did it. [Martin Kraemer]
2834 *) Support DSOs properly on 32-bit HP-UX 11.0
2835 [Dilip Khandekar <dilip@cup.hp.com>]
2837 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2838 [Ralf S. Engelschall]
2840 *) Cleaned APR build environment integration and bootstrap APR
2841 automatically for developers from src/Configure.
2842 [Ralf S. Engelschall]
2844 *) Fixed building of src/support/htpasswd.c
2845 [Ralf S. Engelschall]
2847 *) When generating the Location: header, mod_speling forgot
2848 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2851 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2853 *) Change all pools to APR contexts. This is the first step to
2854 incorporating APR into Apache. [Ryan Bloom]
2856 *) Move "handler not found" warning message to below the check
2857 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2858 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2860 *) Support line-continuation feature in config.option file and
2861 allow the loading of multiple option sections at once via
2862 ``--with-option=<section1>,<section2>,...''
2863 [Ralf S. Engelschall]
2865 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2867 Changes with Apache MPM
2869 *) Use asynchronous AcceptEx() and a completion port to accept and
2870 dispatch connections to threads in Windows NT/2000.
2873 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2876 *) Implement the APACI --with-option facility
2877 (per default used the config.option file).
2878 [Ralf S. Engelschall]
2880 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2882 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2883 Replace pre_connection module call with a register_hook call and
2884 implement pre_connection as a hook. The intent is that these hooks will
2885 be extended to allow Apache to be multi-protocol, and also to allow the
2886 calling order to be specified on a per-hook/per-module basis.
2889 *) Implement mpm_* methods as "modules". Each method gets its own
2890 subdir in src/modules (eg: src/modules/prefork). Selection
2891 of method uses Rule MPM_METHOD. [Jim Jagielski]
2893 *) Port the hybrid server from the apache-apr repository as
2894 mpm_mpmt_pthread. [Manoj Kasichainula]
2896 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2897 amongst the unix MPMs.
2899 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2900 signal handling for the new world order. [Dean Gaudet]
2902 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2903 of alloc.c for now. [Dean Gaudet]
2905 *) Handle partial large writes correctly. [Ben Laurie]
2907 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2908 based on IP/port. [Ben Laurie]
2910 *) Port a bunch of modules to the new module structure.
2911 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2913 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2915 *) Basic restructuring to introduce the MPM concept; includes various
2916 changes to the module API... better described by
2917 docs/initial_blurb.txt. [Dean Gaudet]
2919 Changes with Apache pthreads
2921 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2922 buff operations (generally over a network).
2923 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2925 *) Created http_accept abstraction. Added 4 new functions (not exported):
2926 init_accept(), begin_accepting_requests(), get_request(),
2927 stop_accepting_requests() [Bill Stoddard]
2929 *) Fix to ap_rprintf call that allows mod_info to work properly.
2930 [James Morris <jmorris@intercode.com.au>]
2932 *) user and ap_auth_type fields were moved from connection_rec to
2933 request_rec. [Ryan Bloom]
2935 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2936 needed in a threaded server.
2938 *) Initial pthread implementation from from Dean's apache-nspr code.
2939 [Bill Stoddard, Ryan Bloom]
2942 Changes with Apache 1.3.9
2944 *) Remove bogus error message when a redirect doesn't set Location.
2945 Instead, use an empty string to avoid coredump if the error message
2946 was supposed to include a location. [Roy Fielding]
2948 *) Don't allow configure to include mod_auth_digest unless it is
2949 explicitly requested, even if the user asked for all modules.
2952 *) Translate module names to dll names for OS/2 so that they are no more
2953 than 8 characters long and have an extension of "dll" instead of "so".
2956 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2957 Fix test-compile check to check for randbyte instead of trand32.
2958 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2959 and tweak to make Amaya happier. [Ronald Tschalär]
2961 *) Ensure that the installed expat include files are world readable,
2962 just like the other header files. [Martin Kraemer]
2964 *) Fixed generated AddModule adjustments in APACI's `configure' script
2965 in order to allow (new) modules like mod_vhost_alias to be handled
2966 correctly (which was touched by the adjustments for mod_alias).
2967 [Ralf S. Engelschall]
2969 *) For binary builds, add -R flag to apachectl to work around the lack of
2970 an absolute path to the ./libexec directory where the libhttp.ep file
2971 is needed for SHARED_CORE architectures. [Randy Terbush]
2973 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2974 problem observed by some Win95/98 users where they get CGI script
2975 output sent to the console. [Bill Stoddard]
2977 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2978 routines are now called ap_base64* and are 'plain' (i.e., no
2979 pool access or anything clever). Inside util.c the routines acting
2980 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2981 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2982 now but deprecated. [dirkx]
2984 *) Clean up the base64 and SHA1 additions and make sure they are
2985 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2986 files. [Roy Fielding]
2988 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2989 checking. Allow compiling on VS 6.0. [Randy Terbush]
2991 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2993 *) Use TestCompile to search for the truerand library (rather than blindly
2994 assuming its existence). If it is not found, complain (but do not
2995 exit - yet). [Martin Kraemer]
2997 *) We forgot to add the new exported function names to
2998 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3000 *) Add description of -T command-line option to usage().
3001 [Ralf S. Engelschall]
3003 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3004 searched only AFTER libap has been searched, because libap needs
3005 some symbols from libos. [Martin Kraemer]
3007 *) Fix conflict with original mod_digest related to the symbol of the
3008 module dispatch list (which has to be unique for DSO and follow the
3009 usual conventions for the installation procedure).
3010 [Ralf S. Engelschall]
3012 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3013 for other platforms as well. [Martin Kraemer]
3015 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3016 types by AP_LONG and replace reference to renamed variable 'ubuf'
3017 by 'buffer'. [Martin Kraemer]
3019 Changes with Apache 1.3.8 [not released]
3021 *) Flush the output buffer immediately after sending an error or redirect
3022 response, since the result may be needed by the client to abort a
3023 long data transfer or restart a series of pipelined requests.
3024 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3026 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3027 [Ian Turner <iant@sequent.com>] PR#4735
3029 *) Local struct mmap in http_core.c conflicted with system structure
3030 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3032 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3033 [Ronald Tschalär <ronald@innovation.ch>]
3035 *) Fix a memory leak where the module counts were getting messed
3036 up across restarts. [David Harris <dharris@drh.net>]
3038 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3039 properly in mod_access.
3040 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3042 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3043 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3045 *) PORT: Support for compaq/tandem/com.
3046 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3048 *) Added SHA1 password encryption support to easy migration from
3049 Netscape servers. See support/SHA1 for more information.
3050 Caused the separation of ap_md5.c into md5, sha1 and a general
3051 ap_checkpass.c with just a validate_passwd routine. Added a
3052 couple of flags to support/htpasswd. Some reuse of the to64()
3053 function; hence renamed to ap_to64().
3054 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3056 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3057 with ASCII/EBCDIC conversions in "ident" query.
3058 [David McCreedy <McCreedy@us.ibm.com>]
3060 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3061 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3062 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3064 *) Fix SIGSEGV on some systems because the Vary fix below included
3065 a call to table_do with a variable argument list that was not
3066 NULL terminated. Replaced with better implementation. [Roy Fielding]
3068 Changes with Apache 1.3.7 [not released]
3070 *) The "Vary" response header field is now sanitised right before
3071 the header is sent back to the client. Multiple "Vary" fields
3072 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3073 "Vary: host, negotiate, host, accept-language") are reduced to
3074 single instances. This is a better solution than the force-no-vary
3075 one (which is still valid for clients that can't cope with Vary
3076 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3078 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3080 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3081 least on Linux and FreeBSD for now.
3084 *) Win32: More apache -k restart work. Restarts are now honored
3085 immediately and connections in the listen queue are -not- lost.
3086 This is made possible by the use of the WSADuplicateSocket()
3087 call. The listeners are opened in the parent, duplicated, then
3088 the duplicates are passed to the child. The original listen sockets
3089 are not closed by the parent across a restart, thus the listen queue
3091 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3093 *) Fix handling of case when a client has sent "Expect: 100-continue"
3094 and we are going to respond with an error, but get stuck waiting to
3095 discard the body in the pointless hope of preserving the connection.
3096 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3098 *) Fix 'configure' to work correctly with SysV-based versions of
3099 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3101 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3102 built-in values. Add "-e" option which works like -i but doesn't
3103 install the DSO; useful for editing httpd.conf with apxs. Fix
3104 editing code so that multiple invocations of apxs -a will not
3105 create duplicate LoadModule/AddModule entries; apxs can now be
3106 used to re- enable/disable a module. [Wilfredo Sanchez]
3108 *) Win32: Update the server to use Winsock 2. Specifically, link with
3109 ws2_32.lib rather than wsock32.lib. This gives us access to
3110 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3111 Win 95 users may need to update their TCP/IP stack to pick up
3112 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3113 [Bill Stoddard stoddard@raleigh.ibm.com]
3115 *) Win32: Redirect CGI script stderr (script debug info) into the
3116 error.log when CGI scripts fail. This makes Apache on Win32
3117 behave more like Unix.
3118 [Bill Stoddard stoddard@raleigh.ibm.com]
3120 *) Fixed `httpd' usage display: -D was missing.
3121 [Ralf S. Engelschall] PR#4614
3123 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3124 [Ralf S. Engelschall] PR#4561, PR#4562
3126 *) OS/2: Fix problem with accept lock semaphores where server would die with
3127 "OS2SEM: Error 105 getting accept lock. Exiting!"
3128 [Brian Havard] PR#4505
3130 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3131 [Randy Terbush <randy@covalent.net>]
3133 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3134 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3136 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3137 command potentially _is_ GCC. [Ralf S. Engelschall]
3139 *) Fix apxs build issues on AIX
3140 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3142 *) DocumentRoot Checking: Under previous versions, when Apache
3143 first started up, it used to do a stat of each DocumentRoot to
3144 see if it existed and was a directory. If not, then an error
3145 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3146 does not exist, you will get error messages in error_log. If
3147 the '-t' command line option is used (to check the configuration)
3148 the check of DocumentRoot IS performed. An additional command
3149 line option, '-T', has been added if you want to avoid the
3150 DocumentRoot check even when checking the configuration.
3153 *) Win32: The query switch "apache -S" didn't exit after showing the
3154 vhost settings. That was inconsistent with the other query functions.
3155 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3157 *) Win32: Changed behaviour of apache -k restart.
3158 Previously, the server would drain all connections in the stack's
3159 listen queue before honoring the restart. On a busy server, this
3160 could take hours. Now, a restart is honored almost immediately.
3161 All connections in Apache's queues are handled but connections in
3162 the stack's listen queue are discarded. Restart triggered by
3163 MaxRequestPerChild is unchanged.
3164 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3166 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3167 the accept loop. Good for a 5% performance boost. Cleaned up
3168 parent/child process management code.
3169 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3171 *) Added ceiling on file size for memory mapped files.
3172 [John Giannandrea <jg@meer.net>] PR#4122
3174 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3175 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3176 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3178 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3179 use this at least for Expat. [Ralf S. Engelschall]
3181 *) Allow .module files to specify libraries with Lib:.
3184 *) Allow SetEnvIf[NoCase] to test environment variables as well
3185 as header fields and request attributes. [Ken Coar]
3187 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3188 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3190 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3191 never accepted into any standard, and it opens up certain DoS
3192 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3194 *) TestCompile updated. We can now run programs and output the
3195 results during the Configure process. [ Jim Jagielski]
3197 *) The source is now quad (long long) aware as needed. Specifically,
3198 the Configure process determines the correct size of off_t and
3199 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3200 provides for the 'q' format qualifier (if quads are not available,
3201 'q' is silently "demoted" to long). [Jim Jagielski]
3203 *) When the username or password fed to htpasswd is too long, include the
3204 size limit in the error message. Also report illegal characters
3205 (currently only ':') in the username. Add the size restrictions
3206 to the man page. [Ken Coar]
3208 *) Fixed the configure --without-support option so it doesn't result in
3209 an infinite loop. [Marc Slemko]
3211 *) Piped error logs could cause a segfault if an error occured
3212 during configuration after a restart.
3213 [Aidan Cully <aidan@panix.com>] PR#4456
3215 *) If a "Location" field was stored in r->err_headers_out rather
3216 than r->headers_out, redirect processing wouldn't find it and
3217 the server would core dump on ap_escape_html(NULL). Check both
3218 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3219 if Location isn't set. [Doug MacEachern, Ken Coar]
3221 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3222 of the Expat 1.0.2 distribution. [Greg Stein]
3224 *) Replace regexec() calls with calls to a new API stub function
3225 ap_regexec(). This solves problems with DSO modules which use the regex
3226 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3228 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3229 environment variables can be set according to the protocol version
3230 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3232 *) Add DSO support for OpenStep (Mach 4.2) platform.
3233 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3235 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3236 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3238 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3239 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3241 *) Better DSO flags recognition on NetBSD platforms using ELF.
3242 [Todd Vierling <tv@pobox.com>] PR#4310
3244 *) Always log months in english format for %t in mod_log_config.
3245 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3247 *) Support for server-parsed and multiview-determined ReadmeName and
3248 HeaderName files in mod_autoindex. Removed the restriction on
3249 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3250 routines will deal with the access issues. (It's now possible to
3251 have {site|group|project|customer|...} wide readmes and headers.)
3252 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3255 *) When stat() fails, don't assume anything about the contents of
3256 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3258 *) It's OK for a semop to return EINTR, just loop around and try
3259 again. [Dean Gaudet]
3261 *) Fix configuration engine re-entrant hangups, which solve a
3262 handful of problems seen with mod_perl <Perl> configuration sections
3263 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3265 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3266 by default when building with APACI; allow for platform-specific
3267 variable defaults in configure. [Wilfredo Sanchez]
3269 *) Do setgid() before initgroups() in http_main; some platforms
3270 zap the grouplist when setgid() is called. This was fixed in
3271 suexec earlier, but the main httpd code missed the change.
3272 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3274 *) Add recognition of .tgz as a gzipped tarchive.
3275 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3277 *) mod_include's fsize/flastmod should allow only relative paths, just
3278 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3280 *) OS/2: Add support for building loadable modules using DLLs.
3283 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3286 *) Fix minor but annoying bug with the test for Configuration.tmpl
3287 being newer than Configuration so that it is less likely to fail
3288 when using APACI and shadow sources. [Wilfredo Sanchez]
3290 *) PORT: Add initial support for Mac OS (versions 10.0 and
3291 greater). Use Mac OS X Server layout for now. Clean up dyld code
3292 in unix/os.c, and don't install the dyld error handlers, which
3293 are no longer needed in Mac OS. [Wilfredo Sanchez]
3295 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3296 locations to appropriate ones for user-built (as opposed to
3297 system) installs. [Wilfredo Sanchez]
3299 *) Modify mod_autoindex's handling of AddDescription so that the
3300 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3302 *) Add functionality to the install-bindist.sh script created by
3303 binbuild.sh to use tar when copying distribution files to the
3304 serverroot. This allows upgrading an existing installation
3305 without nesting the new distribution in the old.
3307 install-bindist.sh now detects the local perl5 path to install
3308 apxs and dbmmanage with proper path to perl interpreter.
3310 Add an install-binsupport target which copies the source files
3311 for apxs and dbmmanage to bindist to allow these scripts to
3312 be properly installed relative to the destination serverroot.
3313 [Randy Terbush, Covalent Technologies, randy@covalent.net]
3315 *) Fix intermittent SEGV in ap_proxy_cache_error() in

3327 *) Force the LANG envariable to the known state of "C" so that we
3328 have assurance about how string manipulators (e.g., tr) will
3329 function. [Ken Coar] PR#1630
3331 *) Add a directive to allow customising of the tracking cookie name.
3332 [Ken Coar] PR#2921, 4303
3334 *) Add "force-no-vary" envariable to allow servers to work around
3335 clients that choke on "Vary" fields in the response header.
3336 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
3338 *) Fixed a bug in mod_dir that causes a child process will infinitely
3339 recurse when it attemps to handle a request for a directory wnd the
3340 value of the DirectoryIndex directive is a single dot. Also likely
3341 to happen for anyother values of DirectoryIndex that will map back

3423 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
3425 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
3428 *) Correct an apparent typo: on the Windows and MPE platforms, the
3429 htpasswd utility was limiting passwords to only 8 characters.
3432 *) EBCDIC platforms: David submitted patches for two bugs in the
3433 MD5 digest port for EBCDIC machines:
3434 a) the htdigest utility overwrote the old contents of the digest file
3435 b) the Content-MD5 header value (ContentDigest directive) was wrong
3436 when the returned file was not converted from EBCDIC, but was a
3437 binary (e.g., image file) in the first place.
3438 [David McCreedy <mccreedy@us.ibm.com>]
3440 *) support/htpasswd now permits the password to be specified on the
3441 command line with the '-b' switch. This is useful when passwords
3442 need to be maintained by scripts -- particularly in the Win32
3443 environment. [Ken Coar]
3445 *) Win32: Win32 multiple services patch. Added capability to install and
3446 run multiple copies of apache as individual services.
3449 apache -n apache1 -i -f c:/httpd.conf
3450 Installs apache as service 'apache1' and associates c:/httpd.conf
3453 Starts apache1 service.
3455 Stops apache1 service
3458 apache -n apache2 -i
3459 Installs apache as service 'apache2'. httpd.conf is located under
3460 the default server root (/apache/conf/httpd.conf).
3462 Starts apache2 service.
3465 apache -n apache3 -i -d c:/program files/apache
3466 Install apache as service 'apache3' and sets server root to
3467 c:/program files/apache.
3470 apache -n apache2 -k restart
3471 Restart apache2 service
3473 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
3475 *) Correct the signed/unsigned character handling for the MD5 routines;
3476 mismatches were causing compilation problems with gcc -pedantic and
3477 in the TPF cross-compilation. [Ken Coar]
3479 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3480 a roughly 5 fold speed up. [Brian Havard]
3482 *) proxy ftp: instead of using the hardwired string "text/plain" as
3483 a fallback type for files served by the ftp proxy, use the
3484 ap_default_type() function to determine the configured type.
3485 This allows for special configurations like
3486 <Directory proxy:ftp://some.host>
3487 DefaultType gargle/blurb
3489 Additionally, add the Content-Encoding: header to FTP proxy replies
3490 when the encoding is defined (by the AddEncoding directive).
3491 Because it was missing, it was almost impossible to browse compressed
3492 files using the FTP proxy (works now perfectly in Communicator).
3493 The ftp proxy now also returns the Date: and Server: header lines (if not
3494 much else... This code is "somewhat" broken) like normal requests do.
3497 *) Be more smart in APACI's configure script when determining the UID/GID
3498 for User/Group directives and use the determined UID/GID to initialize
3499 the permissions on the proxycachedir.
3500 [Dirk-Willem van Gulik, Ralf S. Engelschall]
3502 *) Changed the forking-prior-to-cleanup in the proxy module to first
3503 check wether it actually needs to collect garbage. This reduces
3504 the number of fork()s from one/request to just the odd one an hour.
3505 [Dirk-Willem van Gulik]
3507 *) Added proxy, auth and header support to src/support/ab.c. Added a
3508 README file to src/support/
3509 [Dirk-Willem van Gulik]
3511 *) Don't hard-code the path to AWK in --shadow bootstrapping Makefile.
3512 [Ralf S. Engelschall] PR#4050
3514 *) Add support for DSO module compilation on BSD/OS 3.x.
3515 [Randy Terbush, Covalent Technologies]
3517 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
3518 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
3519 option) were substituted with $(TARGET).conf, etc. Same for other strings
3520 with dots where the dot wasn't matched as plain text.
3521 [Ralf S. Engelschall]
3523 *) PORT: Add support for FreeBSD 4.x [Ralf S. Engelschall]
3525 *) Fix verbose output of APACI configure (option -v)
3526 [Martin Kraemer, Ralf S. Engelschall]
3528 Changes with Apache 1.3.6
3530 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
3532 Changes with Apache 1.3.5 [not released]
3534 *) M_INVALID needed a value within the scope of METHODS so that unknown
3535 methods can be access controlled. [Roy Fielding] PR#3821
3537 *) Added PassAllEnv; makes server's entire environment available
3538 to CGIs and SSIs executed within directive's scope. [Ken Coar]
3540 *) ap_uuencode() always added two trailing '='s and encoding of
3541 8 bit characters on a machine with signed char may produced
3542 incorrect results. Additionally ap_uuencode() should now
3543 work correctly on EBCDIC platforms.
3544 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
3546 *) WIN32: Binary installer now runs the configuration DLL before
3547 the reboot prompt (which is only given if MSVCRT.DLL system
3548 DLL is new or updated). This should avoid the configuration
3549 directory being empty after installation. [Paul Sutton]
3550 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988
3552 *) WIN32: Binary installer now creates Start menu options to start
3553 and stop Apache as a console application and to uninstall
3554 the Apache service on NT. [Paul Sutton] PR#3741
3556 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
3558 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
3559 have been reported with flock() locking (probably related to kernel
3560 version). [Dean Gaudet] PR#2723, 3531
3562 *) Using APACI, the main config file (usually httpd.conf) was
3563 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez
3564 <wsanchez@apple.com>]
3566 *) PORT: AIX does not require the SHARED_CODE "hack"
3567 [Ryan Bloom <rbb@raleigh.ibm.com>]
3569 *) Set-Cookie headers were being doubled up for some CGIs by the O(n^2)
3570 avoidance code added in 1.3.3.
3571 [Dean Gaudet, Jeff Lewis <lewis@stanford.edu>] PR#3872
3573 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3574 for 8-bit safeness. [Dean Gaudet]
3576 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3577 because SPARCs have a small machine-specific maximum size for the Global
3578 Offset Table which is often exceeded when compiling one of the larger
3579 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3581 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
3582 DSO/DLL section because it's a directive from mod_status and isn't
3583 available before the DLL of mod_status is loaded.
3584 [Martin POESCHL <mpoeschl@gmx.net>] PR#3936
3586 *) SECURITY: Fix a bug in the calculation of the buffer size for the line
3587 continuation facility in Apache's configuration files which could
3588 lead to a buffer overflow situation.
3589 [Thomas Devanneaux <Thomas.Devanneaux@enst.fr>] PR#3617
3591 *) Make documentation and error messages of APACI's --activate-module=FILE
3592 option more clear. [Jan Wolter <janc@wwnet.net>] PR#3995
3594 *) Fix the gcc version check (for enabling the `inline' facility) to
3595 really support all future gcc versions >= 2.7 until we know more.
3596 [John Tobey <jtobey@banta-im.com>] PR#3983
3598 *) Let APACI's configure script correctly complain for unknown --enable-XXX
3599 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
3601 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
3602 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
3603 possible buffer overflows. [Ralf S. Engelschall]
3605 *) Remove no longer used non-API function ap_single_module_init().
3606 [Ralf S. Engelschall]
3608 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
3611 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
3612 to make platform installations easier. [Wilfredo Sanchez]
3614 *) In configure, do not append the target name to the directory path if
3615 the path already contains "apache". [Ralf S. Engelschall]
3617 *) SIGPIPE is now ignored by the server core. The request write routines
3618 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3619 correctly check for output errors and mark the connection as aborted.
3620 Replaced many direct (unchecked) calls to ap_b* routines with the
3621 analogous ap_r* calls. [Roy Fielding]
3623 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3624 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3625 Furthermore map lookups for non-existent keys are now cached as well.
3626 Additionally "txt" maps are now parsed with simple string functions
3627 instead of using ap_pregcomp(). As a side effect a bug that prevented
3628 the usage of keys containing the "," character was fixed.
3629 The changes drastically improve the performance when large rewrite maps
3631 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
3633 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
3634 other than GET, and const'd the definition of method in request_rec.
3637 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
3639 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3640 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3642 *) Add %V to mod_log_config, this logs the hostname according to the
3643 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3644 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3646 *) Add support for \n and \t to mod_log_config, can be used to produce
3647 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3649 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
3651 *) Added informative error messages for failed munmap() and fseek() calls
3652 in http_core.c. [John Bley, Roy Fielding]
3654 *) Added some informative error messages for some failed malloc()
3655 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
3657 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
3658 is removed. This allows <Directory proxy:*> directives to work and
3659 prevents invalid requests from killing the process.
3660 [Brian Havard <brianh@kheldar.apana.org.au>]
3662 *) Reorganised FAQ document.
3663 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
3665 *) src/support/: The ApacheBench benchmark program was overhauled by
3666 David N. Welton: you can now have it generate an HTML TABLE, presumably
3667 for integration into other HTML sources. David updated the ab man page
3668 as well and added some missing descriptions. Thanks!
3669 [David N. Welton <davidw@prosa.it>]
3671 *) Win32: The filename validity checker now allows filenames containing
3672 characters in the range 0x80 to 0xff (for example accented characters).
3673 [Paul Sutton] PR#3890
3675 *) Added conditional logging based upon environment variables to
3676 mod_log_config. mod_log_referer and mod_log_agent
3677 are now deprecated. [Ken Coar]
3679 *) Allow apache acting as a proxy server to relay the real
3680 reason of a failure to a client rather than the "internal
3681 server error" it does currently. The general exposure mechanism
3682 can be triggered by any module by setting the "verbose-error-to"
3683 note to "*"; this allows more than just proxy errors to be exposed.
3684 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3686 *) Moved man pages for ab and apachectrl to section 8.
3687 [Wilfredo Sanchez, Roy Fielding]
3689 *) Added -S option to install.sh so that options can be passed to
3690 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3692 *) Tweak modules Makefile generated by Configure so that it handles
3693 the test case of no modules being selected. [chaz@reliant.com]
3695 *) Added a <LimitExcept method ...> sectioning directive that allows
3696 the user to assign authentication control to any HTTP method that
3697 is *not* given in the argument list; i.e., the logical negation
3698 of the <Limit> directive. This is particularly useful for controlling
3699 access on methods unknown to the Apache core, but perhaps known by
3700 some module or CGI script. [Roy Fielding, Tony Finch]
3702 *) Prevent apachectl from complaining if the PIDFILE exists but
3703 does not contain a process id, as might occur if the server is
3704 being rapidly restarted. [Wilfredo Sanchez]
3706 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3708 *) Entity tag comparisons for If-Match and If-None-Match were not being
3709 performed correctly -- weak tags might cause false positives. Also,
3710 strong comparison wasn't properly enforced in all cases.
3711 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
3713 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
3716 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3717 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3719 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3720 to util.c for parsing an HTTP header field value to extract the next
3721 list item, taking into account the possible presence of nested comments,
3722 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3723 insignificant whitespace and lowercases non-quoted tokens.
3724 [Roy Fielding] PR#2065
3726 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3727 code different from 500. This allows the proxy to, e.g., return
3728 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3730 *) Fix ordering of language variants for the case where the traditional
3731 negotiation algorithm is being used with multiple language variants
3732 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3734 *) Do not round the TCN quality calculation to 5 decimal places,
3735 unlike RFC 2296, because the calculation might need 12 decimal places
3736 to get the right result. [Roy Fielding]
3738 *) Remove unused code to disable transparent negotiation when
3739 negotiating on encoding only, as we now handle encoding too
3740 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3741 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3742 some debugging statements within mod_negotiation. [Koen Holtman]
3744 *) Fixed a rare memory corruption possibility in mod_dir if the index
3745 file is negotiable and no acceptable variant can be found.
3746 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3748 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3749 searching the Win32 registry for script interpreters.
3752 *) Win32: The compiled-in default filename for the error log is now
3753 error.log, which matches the default in the distributed httpd.conf.
3756 *) Win32: Any error messages from -i or -u command line options are now
3757 displayed on the console output rather than sent to the error log.
3758 Also the "Running Apache..." message is not output unless Apache is
3759 going to serve requests. [Paul Sutton]
3761 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3762 and use a private significator ('$apr1$') to mark passwords as
3763 being smashed with our own algorithm. Also abstract the password
3764 checking into a new ap_validate_password() routine. [Ken Coar]
3766 *) Win32: The filename validity checker now allows "COM" but refuses
3767 access to "COM1" through "COM4". This allows filenames such
3768 as "com.name" to be served. [Paul Sutton] PR#3769.
3770 *) BS2000: Adapt to the new ufork() system call interface which will
3771 make subtasking easier on the OSD/POSIX mainframe environment.
3774 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3775 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3777 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
3778 use `.db' instead of `.pag' not only for FreeBSD, but also when
3779 the NDBM library looks like Berkeley-DB based.
3780 [Ralf S. Engelschall] PR#3773
3782 *) Add ability to handle DES or MD5 authentication passwords.
3783 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
3785 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
3787 *) SECURITY: Avoid some buffer overflow problems when escaping
3788 quoted strings. (This overflow was on the heap and we believe
3789 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3791 *) Let src/Configure be aware of CFLAGS options starting with plus
3792 signs as it's the case for the HP/UX compiler.
3793 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3795 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3796 and check to see if the tar we wind up with supports '-h'.
3797 [Jim Jagielski] PR#3671
3799 *) A consistent and conservative style for all shell scripts has been
3800 implemented. Basically, all shell string tests use the traditional
3801 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3802 to protect against bare null variable strings (ie: wrapping both
3803 sides with double quotes and prepending 'x'). 'x' was chosen
3804 because it's more universal and hopefully easier for old shell
3805 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3808 *) The status module now prints out both the main server generation as
3809 well as the generation of each process. Also, the vhost info is
3810 printed with '?notable'. [Jim Jagielski]
3812 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3813 and this makes its functions available to things in src/support.
3816 Changes with Apache 1.3.4
3818 *) Renamed macros status_drops_connection to ap_status_drops_connection
3819 and vestigial scan_script_header to ap_scan_script_header_err,
3820 mostly for aesthetic reasons. [Roy Fielding]
3822 *) The query switch "httpd -S" didn't exit after showing the
3823 vhost settings. That was inconsistent with the other query functions.
3826 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3827 filename to the end of the STANDARD_MODULE_STUFF. Its
3828 presence at the beginning prevented reporting of the filename
3829 for modules compiled before 1 January 1999. [Ken Coar]
3831 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3832 to detect and prevent access to special DOS device file names.
3833 [Paul Sutton, Ken Parzygnat]
3835 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3836 and Makefile_win32_debug.txt (debug build) that work on Win95.
3837 Run each of the following from the src directory:
3838 nmake /f Makefile_win32.txt # compiles normal build
3839 nmake /f Makefile_win32.txt install # compiles and installs
3840 nmake /f Makefile_win32.txt clean # removes compiled junk
3841 nmake /f Makefile_win32_debug.txt # compiles debug build
3842 nmake /f Makefile_win32_debug.txt install
3843 nmake /f Makefile_win32_debug.txt clean
3846 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3847 to build binary distributions. [Lars Eilebrecht]
3849 *) IndexOptions SuppressColumnSorting only turned off making
3850 the column headers anchors; you could still change the display
3851 order by manually adding a '?N=A' or similar query string to the
3852 URL. Now SuppressColumnSorting locks in the sort order so
3853 it can't be overridden this way. [Ken Coar]
3855 *) Added IndexOrderDefault directive to supply a default sort order
3856 for FancyIndexed directory listings. [Ken Coar] PR#1699
3858 *) Change the ap_assert macro to a variant that works on all platforms.
3859 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3861 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3862 search for an underscore on dlsym() (as it's already the case
3863 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3865 *) Small fix for mod_env.html: The module was documented as to be _not_
3866 compiled into Apache per default, although it _IS_ compiled into
3867 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3869 *) Instead of fixing a bug in the generation procedure for config.status (a
3870 backslash was missing) we remove the bug together with it's complete
3871 context because the special cases of the past can now no longer occur
3872 because of the recent magic for the --with-layout default.
3873 [Ralf S. Engelschall] PR#3590
3875 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3876 making sure the src/support/ tools are _forced_ to be build last (they
3877 depend on other libraries).
3878 [Markus Theissinger <markus.theissinger@gmx.de>]
3880 *) Fix installation procedure: Now that os-inline.c is actually used (a
3881 recently fixed bug prevented this) we need to also install os-include.c
3882 in addition to os.h into the PREFIX/include/ location or building of
3883 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3885 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3886 allow us to distinguish between a garbled DSO (or even a file which isn't
3887 an Apache module DSO at all) and a DSO which doesn't match the current
3888 Apache API. [Ralf S. Engelschall] PR#3152
3890 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3891 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3892 match case insensitive (this especially avoids nasty patterns like
3893 `[tT][eE][sS][tT]'). Second two additional internal map functions
3894 `escape' and `unescape' were added which can be used to escape/unescape
3895 to/from hex-encodings in URLs parts (this is especially useful in
3896 combination with map lookups).
3897 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3899 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3900 forgotten (because it was a macro) in the symbol renaming process.
3901 [Ralf S. Engelschall]
3903 *) Fix some inconsistencies related to the scopes of directives. The only
3904 user visible change is that the directives `UseCanonicalName' and
3905 `ContentDigest' now use the (more correct) `Options' scope instead of
3906 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3908 *) Using DSO, the Server token was being mangled. Specifically, the
3909 module's token was being added first before the Apache token. This
3910 has been fixed. [Jim Jagielski]
3912 *) Major overhaul of mod_negotiation.c, part 2.
3913 - properly handle "identity" within Accept-Encoding.
3914 - allow encoded variants in RVSA negotiation and let them appear in
3915 the Alternates field using the non-standard "encoding" tag-list.
3916 - fixed both negotiation algorithms so that an explicitly accepted
3917 encoding is preferred over no encoding if "identity" is not
3918 included within Accept-Encoding.
3919 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3920 of large substring sequences.
3921 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3924 *) Major overhaul of mod_negotiation.c, part 1.
3925 - cleanups to mod_negotiation comments and code structure
3926 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3927 support for everything in the upcoming HTTP/1.1
3928 revision (draft-ietf-http-v11-spec-rev-06.txt).
3929 - language tag matching also handles tags with more than 2
3931 - empty Accept, Accept-Language, Accept-Charset headers are
3932 processed correctly; previously an empty header would make all
3933 values acceptable instead of unacceptable.
3934 - allowed for q values in Accept-Encoding
3935 - added support for transparent content negotiation (rfc2295 and
3936 rfc2296) (though we do not implement all features in these drafts,
3937 e.g. no feature negotiation). Removed old experimental version.
3938 - implemented 'structured entity tags' for better cache correctness
3939 (structured entity tags ensure that caches which can deal with Vary
3940 will (eventually) be updated if the set of variants on the server
3942 - this involved adding a vlist_validator element to request_rec
3943 - this involved adding the ap_make_etag() function to the global API
3944 - modified guessing of charsets used by Apache negotiation algorithm
3945 to guess 'no charset' if the variant is not a text/* type

3976 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
3979 *) Update APXS manual page: some -q option arguments were missing
3980 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3982 *) Cleanup the command line options: `-?' was documented to show
3983 the usage list but does it with an error because `?' is not a valid
3984 command. OTOH a lot of users expect `-h' to print such a usage list and
3985 instead are annoyed for ages by our huge unreadable list of directives.
3986 So we now changed the command line options this way:
3988 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3989 very similar to the popular linker option.
3991 Intent: while -l gives the small list of modules, -L now gives the
3992 large list of directives implemented by these modules. This is also
3993 consistent with -v (short version info) and -V (large version info).
3995 Intent: it's now the expected option ;-)
3996 The manual page was adjusted accordingly.

3999 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4000 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4002 *) Removed recently introduced bugs and disfigurements in APACI:
4003 o fixed argument line processing: using $args was broken: It was not
4004 initialized and using args="$args $apc_option" and even args="$args
4005 \"$apc_option\"" fails in the second processing round for any arguments
4006 containing whitespaces. The only correct way is to use the construct
4007 "$@" (but not possible here) or iterate _both_ times over the implicit
4008 argument line (no argument to for-loop) which is what we now use.
4009 o make --with-layout=Apache the default without creating
4010 redundancy (copying the --with-layout block in the argument parsing
4011 loop). We achieve this by using the "$@" construct together with the
4012 `set' command to prepend --with-layout=Apache to the command line in
4013 case --with-layout is not used.
4014 o fixed auto-suffix handling now that config.layout exists.
4015 Paths which are auto-suffixed are marked with a trailing plus sign in
4016 config.layout and every path now can be marked this way (not only the
4017 four paths for which we do it currently). Additionally the suffix is
4018 no longer a static one. Instead it's now `/<target>' where <target> is
4019 the argument of the --target option or per default `httpd'.
4020 o allow also tabs (and only spaces) where we match whitespaces
4021 o various fixes and cleanups related to used shell coding style
4022 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4023 o trimmed output of --help to fit into 80 columns

4086 procedure of mod_rewrite: very long keys were truncated.
4087 [Ralf S. Engelschall]
4089 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4090 identifier, currently "Apache" and "GNU" are pre-defined in the file
4091 config.layout. Custom layouts are possible by using FILE:ID as the
4092 argument where the layout ID is taken from FILE.
4094 The config.layout file consists of <Layout ID>..</Layout> sections
4095 where inside those sections "path_variable: path_value" pairs can be
4096 specified. These lines are converted to path_variable='path_value'.
4098 *) Add a DefaultLanguage directive so that files missing a language
4099 extension (e.g., .fr, .de) can be labelled as being some other
4100 default language. DefaultLanguage can appear in <Directory> and
4101 <Files> containers as well as .htaccess files. [Paul Sutton]

4416 mod_auth_db to both be friendly to users who wants to use this version
4417 and to avoid problems under platforms where only version 2.x is present.
4418 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
4420 *) When using ap_log_rerror(), make the error message available to the
4421 *ERROR_NOTES envariables by default. [Ken Coar]
4423 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
4424 You now must define a BS2000Account name for the server User.
4425 This has fewer security implications than the old approach.
4428 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4429 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4430 platform to make the braindead HPUX linker happy. Notice, for the module
4431 DSOs we don't have to use this, because these are loaded manually (and
4432 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

4441 platforms where `nogroup' exists in /etc/group. [Ralf S. Engelschall]
4443 *) Make PrintPath work generically instead of having one version
4444 strictly for OS/2. [Jim Jagielski, Brian Havard]
4446 *) Fix the recently introduced C header file checking: We now use the C
4447 pre-processor pass only (and no longer the complete compiler pass) to
4448 determine whether a C header file exists or not. Because only this way
4449 we're safe against inter-header dependencies (which caused horrible
4450 portability problems). The only drawback is that we now have a CPP
4451 configuration variable which has to be determined first (we do a similar
4452 approach as GNU Autoconf does here). When all fails the user still has
4453 the possibility to override it manually via APACI or src/Configuration.
4454 As a fallback for the header check itself we can directly check the
4455 existance of the file under /usr/include, too.

4489 -msym is just to optimize the DSO statup time a little bit it's safe and
4490 best when we leave it out now. [Ralf S. Engelschall] PR#2969

4496 real internal formatting function). [Ralf S. Engelschall] PR#2941
4498 *) Allow "Include" directives anywhere in the server config

4503 directive allows the configuration of the ports to which a
4504 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4506 *) mod_expires will now act on content that is not sent from a file
4507 on disk. Previously it would never add an Expires: header to
4508 any response that did not come from a file on disk; the only
4509 case where it still doesn't (and can't) add one for that type of
4510 content is if you are using a modification date based setting.

4525 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4526 a common problem of (mis-administrated?) IIS servers, make the apache
4527 proxy immune to these errors (and ignore the duplicates, but log
4528 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4530 *) The <IfModule and <IfDefine block starting directives now only
4531 allow exactly one argument. Previously, the optional negation
4532 character '!' could be separated by whitespace without a syntax
4533 error being reported, albeit defeating the IfModule functionality
4534 (enclosed directives would ALWAYS be executed). By using the
4535 stricter syntax, these hard-to-track errors can be avoided.
4538 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4539 cause the standalone FancyIndexing directive to logically OR
4540 into any existing IndexOptions settings rather than wiping
4541 them out. [Ken Coar]
4543 *) Changes in ftp proxy: make URL parsing simpler by using the
4545 + Add display of the "current directory" in cases where it's
4546 different from the supplied path (e.g., ftp://user@host/ lives
4547 in /home/user, not in /, therefore clicking on "../" in the
4548 starting directory might send us to /home/).
4549 + When ftp login fails, (esp. when a user name was part of the
4550 URL already), we now return [401 Unauthorized ] to allow the
4551 browser to pop up an authorization dialog. This makes passwords
4552 slightly less visible (they don't appear in the regular log files)
4553 and implements a functionality that other www proxy servers
4557 *) Triggered by the recent "Via:" header changes, the proxy module would
4558 dump core for replies with invalid headers (e.g., duplicate
4559 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4560 core dump is avoided. Also, broken replies are not cached.

4571 adjustment feature (no --without-confadjust) with calls to a new helper

4625 vhost, request and client information is not displayed.
4628 *) STATUS is no longer available. Full status information now
4629 run-time configurable using the ExtendedStatus directive.
4632 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4633 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4634 a function which can be used to perform bulk update operations
4635 on tables in a more efficient manner. [Dean Gaudet]
4637 *) SECURITY: Added compile-time and configurable limits for
4638 various aspects of reading a client request to avoid some simple
4639 denial of service attacks, including limits on maximum request-line
4640 size (LimitRequestLine), number of header fields (LimitRequestFields),
4641 and size of any one header field (LimitRequestFieldsize). Also added
4642 a configurable directive LimitRequestBody for limiting the size of the

4688 directory was renamed to src/os/os2/ for consistency.
4689 [Brian Havard, Ralf S. Engelschall]
4691 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4692 files (here modules) against other DSO files (here shared libraries).
4693 This is done by determining a subset of LIBS which can be safely used for
4694 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4695 disabled for all platforms to avoid problems with this (experimental)

4916 *) Fix the Guess-DSO-flags-from-Perl stuff in src/Configure: "perl" was
4917 used instead of "$PERL" which contains the correctly determined Perl
4918 interpreter (important for instance on systems where "perl" and "perl5"
4919 exists, like BSDI or FreeBSD, etc).
4920 [Ralf S. Engelschall] PR#2505
4922 *) Move the initial suEXEC-related startup message from plain
4923 fprintf()/stderr to a delayed ap_log_error()-based one to avoid problems
4924 when Apache is started from inetd (instead of standalone). Under this
4925 situation startup messages on stderr lead to problems (the line is sent
4926 to the client in front of the requested document).
4927 [Ralf S. Engelschall] PR#871, PR#1318
4929 *) Add a flag so ap_fnmatch() can be used for case-blind pattern matching.

4933 [Ben Laurie, Bill Stoddard <wgstodda@us.ibm.com>] PR#2274
4935 *) WIN32 SECURITY: Eliminate trailing "."s in path components. These are
4936 ignored by the Windows filesystem, and so can be used to bypass security.
4937 [Ben Laurie, Alexei Kosut].
4939 *) We now attempt to dump core when we get SIGILL. [Jim Jagielski]
4941 *) PORT: remove broken test for MAP_FILE in http_main.c.
4942 [Wilfredo Sanchez <wsanchez@apple.com>]
4944 *) PORT: Change support/apachectl to use "kill -0 $pid" to test if the
4945 httpd is running. This should be more portable than figuring out
4946 which of three dozen different versions of "ps" are installed.
4949 *) WIN32: If we can't figure out how to execute a file in a script
4950 directory, bail out of the request with an error message. [W G Stoddard]
4952 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
4953 these are treated by Win32 as if they are ".." but are not detected by
4954 other machinery within Apache. This is something of a kludge but
4955 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
4957 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
4958 pools and thus pollutes libap (until the pool stuff is moved there).
4961 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
4962 but case-insensitive platforms). New #define for this added to conf.h
4963 (CASE_BLIND_FILESYSTEM). [Ken Coar] PR#2455
4965 *) Enable DSO support for OpenBSD in general, not only for 2.x, because it
4966 also works for OpenBSD 1.x. [Ralf S. Engelschall]
4968 *) PORT: Fix compilation problem on ARM Linux.
4969 [Sam Kington <sam@illuminated.co.uk>] PR#2443
4971 *) Let APACI's configure script determine some configuration parameters
4972 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
4973 remove some of the classical hurdles for new users when setting up
4974 Apache. This is done per default because it is useful for the average
4975 user. Package authors can use the --without-confadjust option to disable
4976 these configuration adjustments.
4977 [Ralf S. Engelschall]
4979 *) Added an EXTRA_DEPS configuration parameter which can be used
4980 to add an extra Makefile dependency for the httpd target, for instance
4981 to external third-party libraries, etc.
4982 [Ralf S. Engelschall]
4984 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
4985 as <IfModule>..</IfModule> sections) which can be used to skip or process
4986 contained commands dependend of ``-D PARAMETER'' options on the command
4987 line. This can be used to achieve logical conditions like <IfDefine
4988 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
4989 and thus especially can be used for conditionally loading DSO-based
4990 modules via LoadModule, etc. [Ralf S. Engelschall]
4992 *) PORT: clean up a warning in mod_status for OS/2. [Brian Havard]
4994 *) Make table elements const. This may prevent obscure errors. [Ben Laurie]
4996 *) Fix parsing of FTP `SIZE' responses in proxy module: The newline was not
4997 truncated which forced following HTTP headers to be data in the HTTP
4998 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5001 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5002 in top-level configure script to avoid sed fails on some platforms (for
5003 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5004 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5006 *) Improve performance of directory listings (mod_autoindex) by comparing
5007 integer keys (last-modified and size) as integers rather than converting
5008 them to strings first. Also use a set of explicit byte tests rather
5009 than strcmp() to check for parent directory-ness of an entry. Oh, and
5010 make sure the parent directory (if displayed) is *always* listed first
5011 regardless of the sort key. Overall performance winnage should be good
5012 in CPU time, instruction cache, and memory usage, particularly for large
5013 directories. [Ken Coar]
5015 *) Add a tiny but useful goody to APACI's configure script: The generation
5016 of a config.status script (as GNU Autoconf does) which remembers the used
5017 configure command and hence can be used to restore the configuration by
5018 just re-running this script or for remembering the configuration between
5020 [Ralf S. Engelschall]
5022 *) Add httpd -t (test) option for running configuration syntax tests only.
5023 If something is broken it complains and exits with a return code
5024 non-equal to 0. This can be used manually by the user to check the Apache
5025 configuration after editing and is also automatically used by apachectl
5026 on (graceful) restart command to make sure Apache doesn't die on restarts
5027 because of a configuration which is now broken since the last (re)start.
5028 This way `apachectl restart' can be used inside cronjobs without having
5029 to expect Apache to be falling down. Additionally the httpd -t can be run
5030 via `apachectl configtest'.

5056 didn't match). [Ralf S. Engelschall]
5058 *) Add an additional "dummy" target to the "$(LIB)" target in generated
5059 modules/xxx/Makefile's to avoid problems with SVR4 Make under "full-DSO"

5141 *) Change usage of perror()+fprintf(stderr,...) in mod_rewrite to
5142 more proper ap_log_error() variants.

5146 script is of type [path/to/]mod_xxx.c because all calculations inside
5147 configure and src/Configure depend on this.
5148 [Ralf S. Engelschall] PR#2307
5150 *) Changes usage of perror/fprintf to stderr to more proper ap_log_error

5160 *) Have NT properly set the directory for CGI scripts
5161 (& other spawned children)
5162 [W G Stoddard <wgstodda@us.ibm.com>]
5164 *) Propagate environment to CGI scripts correctly in Win32.
5165 [W G Stoddard <wgstodda@us.ibm.com>] PR#2294
5167 *) Some symbol renaming:
5168 ap_spawn_child_err became ap_spawn_child
5169 ap_spawn_child_err_buff became ap_bspawn_child
5170 spawn_child was obsoleted and moved to compat.h
5173 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5174 programs: ap_spawn_child_err() is used and the Win32 case now uses
5175 CreateProcess() instead of a low-level execl() (which caused problems in
5176 the past under Win32).
5177 [Ralf S. Engelschall]
5179 *) A few cosmetics and trivial enhancements to APXS to make the
5180 generated Makefile more user friendly. [Ralf S. Engelschall]
5182 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5183 was updated to use the normal apache error processing, thereby allowing
5184 proxy errors to be treated by ErrorDocument's as well. For this
5185 purpose, a new module-to-core communication variable "error-notes"
5186 was introduced; the proxy (and possibly other modules) communicates
5187 its error text using this variable. Its content is copied to a new
5188 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5189 The old proxy special error routine ap_proxy_log_uerror()
5190 was replaced by regular ap_log_error() calls, many messages were made
5192 [Martin Kraemer] PR#494, 1259
5194 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5197 *) Transform the configure message "You need root privileges for suEXEC"
5198 from a fatal error into a (more friendly) warning because the building
5199 ("make") of Apache we can allow, of course. Root privileges are needed
5200 only for the installation step ("make install"). So make sure the
5201 user is aware of this fact but let him proceed as long as he can.
5202 [Ralf S. Engelschall] PR#2288
5204 *) Renamed three more functions to common ap_ prefix which we missed at the
5205 Big Symbol Renaming because they're #defines and not real C functions:
5206 is_default_port(), default_port(), http_method().
5207 [Ralf S. Engelschall]
5209 *) A zero-length name after a $ in an SSI document should cause
5210 just the $ to be in the expansion. This was broken during the
5211 security fixes in 1.2.5. [Dean Gaudet] PR#1921, 2249
5213 *) Call ap_destroy_sub_req() in ap_add_cgi_vars() to reclaim some
5214 memory. [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2252

5217 used under AIX) because of recent changes to function names.
5218 [Ralf S. Engelschall]
5220 Changes with Apache 1.3b7
5222 *) Make sure a MIME-type can be forced via a RewriteRule even when no
5223 substitution takes place, for instance via the following rule:
5224 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
5225 requested by users in the past to force a single script without a .cgi
5226 extension and outside any cgi-bin dirs to be executed as a CGI program.
5227 [Ralf S. Engelschall] PR#2254
5229 *) A fix for protocol issues surrounding 400, 408, and
5230 414 responses. [Ed Korthof]

5234 *) Fix discrepancy in proxy_ftp.c which was causing failures when
5235 trying to connect to certain ftpd's, such as anonftpd.
5236 [Rick Ohnemus <rick@ecompcon.com>]
5238 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
5239 logfile instead of fiddling around itself with child spawning stuff.
5240 [Ralf S. Engelschall]
5242 *) Made RefererIgnore case-insensitive.
5244 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
5247 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
5248 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
5251 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
5253 *) Fix support script `dbmmanage': It was unable to handle some sort
5254 of passwords, especially passwords with "0" chars.
5255 [Ralf S. Engelschall] PR#2242
5257 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5258 [Ben Laurie] PR#2238
5260 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5261 library), so CGI handling has been changed to use Win32 native handles
5262 instead of C file descriptors.
5263 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5265 *) The proxy cache would store an incorrect content-length in the cached
5266 file copy after a cache update. That resulted in repeated fetching
5267 of the original copy instead of using the cached copy.
5268 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5270 *) The Makefiles assumed that DSO files are build via $(LD). This
5271 is broken for two reasons: First we never defined at least LD=ld
5272 somewhere to make sure this works (it was silently assumed that most Make
5273 provide a built-in LD definition - ARGL!) and second using the generic LD
5274 variable is not the truth. Instead a special variable named LD_SHLIB is
5275 reasonable because although "ld" is usually the default, the command for
5276 building DSO files can be "libtool" or even "cc" on some systems.
5277 [Ralf S. Engelschall]
5279 *) Replace the AddVersionPlatform directive with ServerTokens which
5280 provides for more control over the format of the Server:
5281 header line. SERVER_SUBVERSION is no longer supported;
5282 all module should use the ap_add_version_component()
5283 API function instead. [Jim Jagielski]
5285 *) Support for the NCR MP/RAS 3.0
5286 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5288 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5289 not retrieved in src/Configure and thus was not useable.
5290 [Ralf S. Engelschall]
5292 *) Various Makefile consistency cleanups:
5293 - make OSDIR also automatically be relative to src/ like INCDIR
5294 - SUBDIRS is now generated in src/Makefile only and not in
5295 Makefile.config because it is a local define for this location.
5296 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5297 any Makefile but make sure that at least the "-K inline" is kept in
5299 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5300 - updated the dependencies theirself
5301 - removed not existing SHLIB variable from "clean" targets
5302 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5303 already exists and OBJS_PIC are also just plain objects and have not
5304 directly to do with "shared" things. The only difference is that they
5305 contain PIC. So OBJS_PIC is the more canonical name.
5306 - Updated the Makefile-dependency lines for OBJS_PIC
5307 - Removed the Makefile-dependency line in Configure to avoid double
5309 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5310 of xxx.lo as GNU libtool does with its PIC objects
5311 - reduce local complexity in modules Makefile.tmpl by moving the last
5312 existing target "depend" to the generation section in Configure, too.
5313 - removed the historical $(SPACER) which was used in the past together
5314 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5315 is no longer needed.
5316 - force the build and run of the gen_xxx programs under main/ as the
5317 first step before building the objects because it looks cleaner
5318 [Ralf S. Engelschall]
5320 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5323 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5326 *) WIN32: Don't force ISAPI headers to finish with \n.
5327 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5329 *) When opening "configuration" files (like httpd.conf, htaccess
5330 and htpasswd), Apache will not allow them to be non-/dev/null
5331 device files. This closes a DoS hole. At the same time,
5332 we use ap_pfopen to open these files to handle timeouts.
5333 [Jim Jagielski, Martin Kraemer]
5335 *) Apache will now log the reason its httpd children exit if they exit
5336 due to an unexpected signal. (It requires a new porting define,
5337 SYS_SIGLIST, which if defined should point to a list of text
5338 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5340 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5341 like WIN32. Before, Win32 CGI's could have had sporadic failures
5342 if a chdir call from one thread was made between another chdir call
5343 and a spawn in another thread. So, for now don't chdir for CGI scripts
5344 in WIN32. The current CGI "spec" is unclear as to whether it's
5345 necessary. Long-term fix is to either serialize the chdir/spawn combo
5346 or use WIN32 native calls to spawn a process. This temp fix was
5347 necessary to remove this as a showstopper for 1.3's release.
5350 *) Cleanup the suEXEC support in APACI and make it more safe:
5351 1. Add big fat hint in INSTALL about risks and to read the
5352 htdocs/manual/suexec.html document before using the suexec-related
5354 2. Make sure the user has at least provided one --suexec-xxxx option
5355 (specifies suEXEC parameters) in addition to --enable-suexec option.
5356 If only --enable-suexec is given APACI stops with a hint to INSTALL
5357 and htdocs/manual/suexec.html documents.
5358 3. Provide two additional --suexec-xxxx options to make the suEXEC
5359 configuration complete (especially for package maintainers who else
5360 had to patch the source tree) by providing ways to configure minimal
5361 UID/GID and safe PATH, too.
5362 [Ralf S. Engelschall]
5364 *) Cleanup of the `configure --shadow' process:
5365 - make sure the configure script creates its temporary files in the
5366 shadow tree to avoid conflicts with parallel configure runs
5367 - removed unnecessary option "-r" from "rm" call for Makefiles
5368 - make sure the configure scripts creates the shadow-wrapper Makefile
5369 only when no shadow trees already exists
5370 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5371 when no more shadow trees exists
5372 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5373 as fast (in the past it needed 70sec, now it runs just 38sec)
5374 - make sure CVS does not complain about the created files
5375 Makefille.<gnutriple> and directories src.<gnutriple>
5376 [Ralf S. Engelschall]
5378 *) Added the ap_add_version_component() API routine and the
5379 AddVersionPlatform core directive. The first allows modules to
5380 declare themselves in the Server response header field value,
5381 augmenting the SERVER_SUBVERSION define in the Configuration file
5382 with run-time settings (more useful in a loadable-module environment).
5383 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5384 into the server version string. [Ken Coar] PR#2056
5386 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5389 *) Emit the "Accept-Range" header for the default handler.
5390 [Brian Behlendorf] PR#1464
5392 *) Add a note to httpd.conf-dist that apache will on some systems fail
5393 to start when the Group # is set to a negative or large positive value.
5396 *) Make sure the module execution order is correct even when some modules
5397 are loaded under runtime (`LoadModule') via the DSO mechanism:
5398 1. The list of loaded modules is now a dynamically allocated one
5399 and not the original statically list from modules.c
5400 2. The loaded modules are now correctly setup by LoadModule for
5401 later use by the AddModule command.
5402 3. When the DSO mechanism for modules is used APACI's `install'
5403 target now enables all created `LoadModule' lines per default because
5404 this is both already expected by the user _and_ needed to avoid
5405 confusion with the next point and reduces the Makefile.tmpl complexity
5406 4. When the DSO mechanism for modules is used, APACI's `install'
5407 target now additionally makes sure the module list is reconstructed
5408 via a complete `ClearModuleList+AddModule...' entry.
5409 5. The support tool `apxs' now also makes sure an AddModule command
5410 is added in addition to the LoadModule command.
5411 6. The modules.c generation was extended to now contain two
5412 comments to make sure no one is confused by the confusing terminology
5413 of loading/linking (we use load=link+load & link=activate instead of
5414 the obvious load=activate & link=link :-( )
5415 This way now there is no longer a difference under execution time between
5416 statically and dynamically linked modules.

5419 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5420 Big Symbol Renaming. [Ralf S. Engelschall]
5422 *) Add a comment to mod_example.c showing the format of a FLAG command
5425 *) Standardized the time format in mod_status to match that of other
5426 places in the code (e.g. DATE_GMT). PR#1551
5428 *) Fix handling of %Z in timefmt strings for those platforms with no time
5429 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5432 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5433 feature compatible with 'UseCanonicalName off' by changing
5434 r->server->server_hostname to ap_get_server_name(). And I changed some
5435 functions which use r->server->port to use ap_get_server_port() instead,
5436 because if there's no Port directive in the config r->server->port is 0.
5439 *) get/set_module_config are trivial enough to be better off inline. Worth
5440 1.5% performance boost. [Dean Gaudet]
5442 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5443 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5446 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5447 the task environment to the unprivileged User id. Otherwise CGI scripts
5448 would have a way to gain super user access. [Martin Kraemer]
5450 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5451 absolute path, only log base name of logging source as is done
5452 in unix. [Martin Kraemer]
5454 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5455 the encoding type from the Accept-Encoding header (if it's there)

5486 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5487 Additionally the checks for finding the vendor DSO library were moved
5488 from mod_so.c to Configure because first it needs $PLAT etc. and second
5489 mod_so already uses an abstraction layer and does not fiddle with the
5490 vendor functions itself.

5493 *) PORT: Some optimization defines for NetBSD
5494 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5496 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5497 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5499 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5500 AIX variants should work fine, too. Even AIX 3.x should work). This is
5501 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5502 which we put into a os/unix/os-dso-aix.c file.
5503 [Ralf S. Engelschall]
5505 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5506 that we should use NET_SIZE_T == int but the include files force size_t.
5507 [Ralf S. Engelschall]
5509 *) Fix two bugs in select() handling in http_main.c.
5512 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5513 is unset (as it is in situations like timeouts) where it is unclear
5514 whether errno is set or not. [Martin Kraemer]
5516 *) Just having APACI's localstatedir is too general and not enough for most
5517 of the systems. 1.3b6 again required manual APACI patches by package
5518 maintainers from RedHat and FreeBSD because for their filesystem layout a
5519 little bit more flexibility in configuring the paths is needed. Hence we
5520 provide three additional configure options (--runtimedir, --logfiledir,
5521 --proxycachedir) which now can be used for more granular adjustments if
5522 --localstatedir is not enough to fit the particular needs. As a nice
5523 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5524 [Ralf S. Engelschall]
5526 *) Make the install root for "make install" in APACI's Makefile overrideable
5527 by package authors. This way we are even more friendly to package
5528 maintainers (especially Debian and RedHat) who build for the real prefix
5529 via "configure --prefix=/<real>" but use a different local prefix via
5530 "make root=/tmp/apache install" for rolling the package without bristling
5531 the target location on their system.
5532 [Ralf S. Engelschall]
5534 *) Workaround sed limitations in APACI's configure script by now
5535 substituting in chunks of 50 commands (because for instance HPUX's vendor
5536 sed has a limit of max. 98 commands)
5537 [Ralf S. Engelschall] PR#2136
5539 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5540 [Ralf S. Engelschall] PR#2140
5542 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5543 RENAMING process because they are defined as pre-processor macros instead
5544 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5545 [Ralf S. Engelschall]
5547 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5548 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5549 [Ralf S. Engelschall] PR#2139
5551 *) Various bugfixes and cleanups for the APACI configure script:
5552 o fix IFS handling for _nested_ situation
5553 o fix Perl interpreter search: take first one found instead of last one
5554 o fix DSO consistency check
5555 o print error messages to stderr instead of stdout
5556 o add install-quiet for --shadow situation to Makefile stub
5557 o reduce complexity by avoiding sed-hacks for rule and module list loops

5560 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5562 *) Make sure the input field separator (IFS) shell variable is explicitly
5563 initialized correctly before _every_ `for' loop and also restored after
5564 the loops. [Ralf S. Engelschall]
5566 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5567 `magic' files from an existing Apache installation. Because people often
5568 customize these for own MIME and content types.

5575 [Ralf S. Engelschall] PR#2105
5577 *) Let "configure" clear out the users parameters (provided as shell

5606 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5608 *) If you start apache with the -S command line option it will dump
5609 out the parsed vhost settings. This is useful for folks trying
5610 to figure out what is wrong with their vhost configuration.
5611 (Other dumps may be added in the future.) [Dean Gaudet]
5613 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5614 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5617 *) Because /usr/local/apache is the default prefix the ``configure
5618 --compat'' option no longer has to set prefix, again. This way the
5619 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5621 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5622 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5623 to avoid "discard const" warnings. [Ralf S. Engelschall]
5625 *) If a specific handler is set for a file yet the request still
5626 ends up being handled by the default handler, log an error
5627 message before handling it. This catches things such as trying
5628 to use SSIs without mod_include enabled. [Marc Slemko]
5630 *) Fix error logging for the startup case where ap_log_error() still uses
5631 stderr as the target. Now the default log level is honored here, too.

5641 Changes with Apache 1.3b6
5643 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5645 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5646 interface via the similar but proprietary HP/UX shl_xxx-style system
5647 calls. [Ralf S. Engelschall]
5649 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5650 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5651 Make. [Ralf S. Engelschall]
5653 *) ++++ THE BIG SYMBOL RENAMING ++++
5654 To avoid symbol clashes with third-party code compiled into the server,
5655 we globally applied the prefix "ap_" to the following classes of
5657 - Apache provided general functions (e.g., ap_cpystrn)
5658 - Public API functions (e.g., palloc, bgets)
5659 - Private functions which we can't make static (because of
5660 cross-object usage) but should be (e.g., new_connection)
5661 For backward source compatibility a new header file named compat.h was
5662 created which provides defines for the old symbol names and can be used
5663 by third-party module authors.
5666 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5667 problem under SVR4 is that there is no command flag to force the linker
5668 to export the global symbols of the httpd executable therewith they are
5669 available to the DSO's. Instead of problematic hacks like creating a
5670 dummy.so file (containing dummy references to all global symbols) the
5671 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5672 Placing the Apache core code itself into a DSO library named libhttpd.so.
5673 This way the global symbols _HAVE_ to be exported and thus are available
5674 to any manually loaded DSO's under runtime. To reduce the impact to the
5675 user to null we go even further and create a stub httpd executable which
5676 automatically keeps track of the DSO library loading itself and thus
5677 hides the complete mechanism from the user. Although the generation of
5678 this DSO library is automatically triggered for platforms which
5679 essentially need it (mostly all SVR4-derivates) it can be also enabled
5680 manually via the Rule SHARED_CORE. This can be interesting in the future
5681 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5682 features like graceful upgrades, or whatever.
5683 [Ralf S. Engelschall, Martin Kraemer]
5685 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5687 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5688 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5689 conventions while "clean" removes only stuff created by "all" targets,
5690 "distclean" additionally removes the stuff from the configuration
5691 process. This way "make distclean" (hence the name) provides a fresh
5692 source tree as it was for distribution.
5693 [Ralf S. Engelschall]
5695 *) Allow top-level (APACI) Makefile to break on build errors
5696 the same way the src/ subtree Makefiles breaks on them by replacing the
5697 initial APACI sed-subdir-display-kludge with a more clean
5698 variable-passing-solution: variable SDP can optionally hold the subdir
5699 prefix which is consistently used for displaying the subdir movement.
5700 This way even the top-level Makefile can stop correctly on errors as the
5701 user expects. [Ralf S. Engelschall]
5703 *) Fixed ordering of argument checks for RewriteBase directive.
5704 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5706 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5707 indicating that a module is being compiled for dynamic loading. Also
5708 remove #define IS_MODULE from modules and add SHARED_MODULE define
5709 to the mak/dsp files. [Alexei Kosut]
5711 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5712 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5714 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5716 *) Add documentation file and src/Configuration.tmpl entry for the
5717 experimental mod_mmap_static module. Because although it is and marked as
5718 an experimental one it is distributed and thus should be documented and
5719 prepared for configuration the same way as all others modules.
5720 [Ralf S. Engelschall]
5722 *) Add query (-q) option to apxs support tool to be able to manually query
5723 specific settings from apxs. This is needed for instance when you
5724 manually want to access Apache's header files and you need to assemble
5725 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5726 [Ralf S. Engelschall]
5728 *) Now src/Configure uses a fallback strategy for the shared object support
5729 on platforms where no explicit information is available: If a Perl
5730 installation exists we ask it about its shared object support and if it's
5731 the dlopen-style one we shamelessly guess the compiler and linker flags
5732 for creating shared objects from Perls knowledge. Of course, the user is
5733 warning about what we are doing and informed that he should send us
5734 the guessed flags when they work. [Ralf S. Engelschall]
5736 *) Provide APACI --without-support option to be able to disable the build
5737 and installation of the support tools from the src/support/ area.
5738 Although its useful to have these installed per default we should provide
5739 a way to compile and install without them for backward-compatibility.
5740 [Ralf S. Engelschall]
5742 *) Add of the new APache eXtenSion (apxs) support tool for building and
5743 installing modules into an _already installed_ Apache package through the
5744 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5745 this approach actually doesn't need the Apache source tree. The
5746 (APACI-installed) server package is enough, because this now includes the
5747 Apache C header files (PREFIX/include) and the new APXS tool
5748 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5749 module authors to build their Apache modules _OUTSIDE_ the Apache source
5750 tree while avoiding them to fiddle around with the totally platform
5751 dependend way of compiling DSO files. The tool supports all ranges of
5752 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5753 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5754 on-the-fly generate a minimalistic Makefile and sample module for the
5755 first step to provide both a quick success event and to demonstrate the
5756 APXS mechanism to module authors. [Ralf S. Engelschall]
5758 *) Fix core dumps in use of CONNECT in proxy.
5759 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5761 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5762 so that users have examples of how CustomLog can be used.
5765 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5766 the Apache distribution tree. Until Apache 1.3 there was no real
5767 out-of-the-box batch-capable build and installation procedure for the
5768 complete Apache package. This is now provided by a top-level "configure"
5769 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5770 to provide a GNU Autoconf-style frontend which is capable to both drive
5771 the old src/Configure stuff in batch and additionally installs the
5772 package with a GNU-conforming directory layout. Any options from the old
5773 configuration scheme are available plus a lot of new options for flexibly
5774 customizing Apache. [Ralf S. Engelschall]
5776 *) The floating point ap_snprintf code wasn't threadsafe.
5777 Had to remove the HAVE_CVT macro in order to do threadsafe
5778 calling of the ?cvt() floating point routines. [Dean Gaudet]
5780 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
5782 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
5783 [Jim Jagielski] PR#1901
5785 *) BUG: Configure was using TCC and CC inconsistently. Make sure
5786 Configure knows which CC we are using. [Jim Jagielski]
5788 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5789 was defined in a parent directory. [Lars Eilebrecht]
5791 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5792 a generic printf-style routine that can call arbitrary output
5793 routines. Use this to replace http_bprintf.c. Add new routines
5794 psprintf(), pvsprintf() which allocate the exact amount of memory
5795 required for a string from a pool. Use psprintf() to clean up
5796 various bits of code which used ap_snprintf()/pstrdup().
5799 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5800 ap_snprintf() has different semantics and formatting codes than
5801 snprintf(). [Dean Gaudet]
5803 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5804 is necessary on at least Solaris where the /etc/rc?.d scripts
5805 are run with these signals ignored, and "SIG_IGN" settings are
5806 maintained across exec().

5832 [Jürgen Keil <jk@tools.de>] PR#2000
5834 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5835 therefore not exposed to %2F -> '/' translations and 2) the request
5836 is a proxy request, so we're not dealing with a local resource anyway.
5837 Without this, the proxy would fail to work for any URL's with
5838 %2f in them (occurs quite often in
5839 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5841 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5843 *) Make the shared object compilation command more portable by avoiding
5844 the direct combination of `-c' & `-o' which is not honored by some
5845 compilers like UnixWare's cc. [Ralf S. Engelschall]

5856 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5857 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5858 name was really too generic, added documentation for this directive to
5859 the mod_proxy.html and corrected the hyperlink to it in the

5868 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5869 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5870 and per default compiled support programs have manual pages - just to
5871 document our stuff a little bit more and to be able to do really
5872 Unix-like installations ;-) [Ralf S. Engelschall]
5874 *) Major cleanups to the Configure script to make it and its generated
5875 Makefiles again readable and maintainable: add SRCDIR option, removed
5876 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5877 generated sections, consequently added Makefile headers with inheritance
5878 information, added subdir movement messages for easier following where
5879 the build process currently stays (more verbose then standard Make, less
5880 verbose than GNU make), same style to comments in the Configure script,
5881 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5883 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5884 from the ZeusBench benchmarking program and can be used to determine the

5888 [Ralf S. Engelschall]
5890 *) API: Various core functions that are definately not part of the API
5891 have been made static, and a few have been marked API_EXPORT. Still
5892 more have been marked CORE_EXPORT and are not intended for general
5893 use by modules. [Doug MacEachern, Dean Gaudet]
5895 *) mod_proxy was not clearing the Proxy-Connection header from
5896 requests; now it does. This did not violate any spec, however
5897 causes poor interactions when you are talking to remote proxies.
5898 [Marc Slemko] PR#1741
5900 *) Various cleanups to the command line interface and manual pages.
5901 [Ralf S. Engelschall]
5903 *) cfg_getline() was not properly handling lines that did not end
5904 with a line termination character. [Marc Slemko] PR#1869, 1909
5906 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5908 *) Clean up some undocumented behavior of mod_setenvif related to
5909 "merging" two SetEnvIf directives when they match the same header
5910 and regex. Document that mod_setenvif will perform comparisons in
5911 the order they appear in the config file. Optimize mod_setenvif by
5912 doing more work at config time rather than at runtime.
5915 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5916 to allow for modules to overrule them and to reduce redefinition
5917 warnings [Jim Jagielski]
5919 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5922 *) Making the hard-coded cross-module function call mime_find_ct() (from
5923 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5924 checking is really called even for proxy requests except for URLs with
5925 HTTP schemes (because there we can optimize by not running the type
5926 checking hooks due to the fact that the proxy gets the MIME Content-type
5927 from the remote host later). This change cleans up mod_mime by removing
5928 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5929 especially unbundles mod_proxy and mod_mime. This way they both now can
5930 be compiled as shared objects and are no longer tied together.
5931 [Ralf S. Engelschall]
5933 *) util.c cleanup and speedup. [Dean Gaudet]
5935 *) API: Clarification, pstrndup() will always copy n bytes of the source
5936 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5938 *) Mark module command_rec and handler_rec structures const so that they
5939 end up in the read-only data section (and are friendlier to systems
5940 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5942 *) Add check to the "Port" directive to make sure the specified
5943 port is in the appropriate range. [Ben Hyde]
5945 *) Performance improvements to invoke_handler().
5946 [Dmitry Khrustalev <dima@bog.msu.su>]
5948 *) Added support for building shared objects even for library-style modules
5949 (which are built from more than one object file). This now provides the
5950 ability to build mod_proxy as a shared object module. Additionally
5951 modules like mod_example are now also supported for shared object
5952 building because the generated Makefiles now no longer assume there is at
5953 least one statically linked module. [Ralf S. Engelschall]
5955 *) API: Clarify usage of content_type, handler, content_encoding,
5956 content_language and content_languages fields in request_rec. They
5957 must always be lowercased; and the strings pointed to shouldn't
5958 be modified (you must copy them to modify them). Fix a few bugs
5959 related to this. [Dean Gaudet]
5961 *) API: Clarification: except for RAW_ARGS, all command handlers can
5962 treat the char * parameters as permanent, and modifiable. There
5963 is no need to pstrdup() them. Clean up some needless pstrdup().
5966 *) Now mod_so keeps track of which module shared objects with which names
5967 are loaded and thus avoids multiple loading and unloading and irritating
5968 error_log messages. [Ralf S. Engelschall]
5970 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5971 environment variable in the apache core. But that tweaking interferes
5972 with mod_setenv. So don't tweak if the user has specified an explicit
5973 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5975 *) rputs() did not calculate r->sent_bodyct properly.
5976 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5978 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5979 name, or left unset if this value is unavailable. Apache was setting
5980 it to the IP address when unavailable.
5981 [Tony Finch <fanf@demon.net>] PR#1925
5983 *) Various improvements to the configuration and build support for compiling
5984 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5985 OSF1 support with GCC and vendor compilers was added. This way shared
5986 object support is now provided out-of-the-box for FreeBSD, Linux,
5987 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5988 [Ralf S. Engelschall]
5990 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5991 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5992 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5994 *) Fix one more special locking problem for RewriteMap programs in
5995 mod_rewrite: According to the documentation of flock(), "Locks are on
5996 files, not file descriptors. That is, file descriptors duplicated
5997 through dup(2) or fork(2) do not result in multiple instances of a lock,
5998 but rather multiple references to a single lock. If a process holding a
5999 lock on a file forks and the child explicitly unlocks the file, the
6000 parent will lose its lock.". To overcome this we have to make sure the
6001 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6002 the case by opening it in the child_init instead of the module_init API
6003 hook. [Ralf S. Engelschall] PR#1029
6005 *) Change to Location and LocationMatch semantics. LocationMatch no
6006 longer lets a single slash match multiple adjacent slashes in the
6007 URL. This change is for consistency with RewriteRule and
6008 AliasMatch. Multiple slashes have meaning in URLs that they do
6009 not have in (some) filesystems. Location on the other hand can
6010 be considered a shorthand for a more complicated regex, and it
6011 does match multiple slashes with a single slash -- which is
6012 also consistent with the Alias directive.
6013 [Dean Gaudet] related PR#1440
6015 *) Fix bug with mod_mime_magic causing certain files, including files
6016 of length 0, to result in no response from the server.
6019 *) The Configure script now generates src/include/ap_config.h which
6020 contains the set of defines used when Apache is compiled on a platform.
6021 This file can then be included by external modules before including
6022 any Apache header files in case they are being built separately from
6023 Apache. Along with this change, a couple of minor changes were
6024 made to make Apache's #defines coexist peacefully with any autoconf
6025 defines an external module might have. [Rasmus Lerdorf]
6027 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6028 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6029 chance by the API to initialize its per-server configuration and thus
6030 receives the wrong one from the main server. This is now avoided by
6031 remembering the server together with the config structure while
6032 configuring and later assuming there is no config when we see a
6033 difference between the remembered server and the one calling us.
6034 [Ralf S. Engelschall] PR#1790
6036 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6037 is automatically disabled under configure time when the dbm_xxx functions
6038 are not available. Second, two heavy source code errors in the DBM
6039 support code were fixed. This makes DBM RewriteMap's usable again after
6040 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6042 *) Now all configuration files support Unix-style line-continuation via
6043 the trailing backslash ("\") character. This enables us to write down
6044 complex or just very long directives in a more readable way. The
6045 backslash character has to be really the last character before the
6046 newline and it has not been prefixed by another (escaping) backslash.
6047 [Ralf S. Engelschall]
6049 *) When using ProxyPass the ?querystring was not passed correctly.
6050 [Joel Truher <truher@wired.com>]
6052 *) To deal with modules being compiled and [dynamically] linked
6053 at a different time from the core, the SERVER_VERSION and
6054 SERVER_BUILT symbols have been abstracted through the new
6055 API routines apapi_get_server_version() and apapi_get_server_built().
6058 *) WIN32: Preserve trailing slash in canonical path (and hence
6059 in PATH_INFO). [Paul Sutton, Ben Laurie]
6061 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6062 depending on the rev of Solaris and what mixture of modules
6063 are in use. So it has been disabled, and Solaris is back to
6064 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6065 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6066 up static content only servers. Or it may fail unpredictably.
6067 [Dean Gaudet] PR#1779, 1854, 1904
6069 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6072 *) API: Rewrite of absoluteURI handling, and in particular how
6073 absoluteURIs match vhosts. Unless a request is a proxy request, a
6074 "http://host" url is treated as if a similar "Host:" header had been
6075 supplied. This change was made to support future HTTP/1.x protocols
6076 which may require clients to send absoluteURIs for all requests.
6078 In order to achieve this change subtle changes were made to the API. In a
6079 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6080 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6081 by the core, modules must set it during the post_read_request or
6082 translate_names phase.
6084 Plus changes to the virtualhost test suite for absoluteURI testing.
6086 This fixes several bugs with the proxy proxying requests to vhosts
6087 managed by the same httpd.
6090 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6091 code from mod_rewrite. The vhost matching is now performed by a
6092 globally available function matches_request_vhost(). [Dean Gaudet]
6094 *) Reduce memory usage, and speed up ServerAlias support. As a
6095 side-effect users can list multiple ServerAlias directives
6096 and they're all considered.
6097 [Chia-liang Kao <clkao@cirx.org>] PR#1531
6099 *) The "poly" directive in image maps did not include the borders of the
6100 polygon, whereas the "rect" directive does. Fix this inconsistency.
6101 [Konstantin Morshnev <moko@design.ru>] PR#1771
6103 *) Make \\ behave as expected. [Ronald.Tschalaer@psi.ch]
6105 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
6106 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
6108 *) API: A new source module main/util_uri.c; It contains a routine
6109 parse_uri_components() and friends which breaks a URI into its component
6110 parts. These parts are stored in a uri_components structure called
6111 parsed_uri within each request_rec, and are available to all modules.
6112 Additionally, an unparse routine is supplied which re-assembles the URI
6113 components back to an URI, optionally hiding the username:password@ part
6114 from ftp proxy requests, and other useful routines. Within the structure,
6115 you find on a ready-for-use basis:
6116 scheme; /* scheme ("http"/"ftp"/...) */
6117 hostinfo; /* combined [user[:password]@]host[:port] */
6118 user; /* user name, as in http://user:passwd@host:port/ */
6119 password; /* password, as in http://user:passwd@host:port/ */
6120 hostname; /* hostname from URI (or from Host: header) */
6121 port_str; /* port string (integer representation is in "port") */
6122 path; /* the request path (or "/" if only scheme://host was given) */
6123 query; /* Everything after a '?' in the path, if present */
6124 fragment; /* Trailing "#fragment" string, if present */
6125 This is meant to serve as the platform for *BIG* savings in
6126 code complexity for the proxy module (and maybe the vhost logic).
6129 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6130 ${map:key}) available for all location where a string is created in
6131 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6132 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6133 possible expansions are consequently usable at all string creation
6134 locations. [Ralf S. Engelschall]
6136 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6137 and not 1) and the per-virtual-server merging of directives. Now all
6138 directives except `RewriteEngine' and `RewriteOption' are either
6139 completely overridden (default) or completely inherited (when
6140 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325
6142 *) Fix `RewriteMap' program lookup in situations where such maps are
6143 defined but disabled (`RewriteEngine off') in per-server context.
6144 [Ralf S. Engelschall] PR#1431
6146 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6147 server to bind to port 0 rather than 80. [Dean Gaudet]
6149 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6150 (like SunOS and FreeBSD) which don't accept the locking of pipes
6151 directly. A new directive RewriteLock is introduced which can be used to
6152 setup a separate locking file which then is used for synchronization.
6153 [Ralf S. Engelschall] PR#1029
6155 *) WIN32: The server root is obtained from the registry key
6156 HKLM\SOFTWARE\Apache Group\Apache\<version> (version is currently
6157 "1.3 beta"), unless overridden by the -d command line flag. The
6158 value is stored by running "apache -i -d serverroot". [Paul Sutton]
6160 *) Merged os/win32/mod_dll.c into modules/standard/mod_so.c to support
6161 dynamic loading on Win32 and Unix via the same module. [Paul Sutton]
6163 *) Now mod_rewrite no longer makes problematic assumptions on the characters
6164 a username can contain when trying to expand it via /etc/passwd.
6165 [Ralf S. Engelschall]
6167 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6168 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6170 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6171 type but with a special post-processing for the looked-up value: It
6172 parses it into alternatives according to `|' chars and then only one
6173 particular alternative is chosen randomly (this is an essential
6174 functionality needed for balancing between backend-servers when using
6175 Apache as a Reverse Proxy. The looked up value here is a list of
6176 servers). Second, `int' with the built-in maps named `tolower' and
6177 `toupper' which can be used to map URL parts to a fixed case (this is an
6178 essential feature to fix the case of server names when doing mass
6179 virtual-hosting with the help of mod_rewrite instead of using
6180 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6181 Jay Soffian <jay@cimedia.com>] PR#1631
6183 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6184 This directive lets Apache adjust the URL in Location-headers on HTTP
6185 redirect responses sent by the remote server. This way the virtually
6186 mapped area is no longer left on redirects and thus by-passed which is
6187 especially essential when running Apache as a reverse proxy.
6188 [Ralf S. Engelschall]
6190 *) Hide Proxy-Authorization from CGI/SSI/etc just like Authorization is
6191 hidden. [Alvaro Martinez Echevarria]
6193 *) Apache will, when started with the -X (single process) debugging flag,
6194 honor the SIGINT or SIGQUIT signals again now. This capability got lost
6195 a while ago during OS/2 signal handling changes.
6197 *) [PORT] Work around the fact that NeXT runs on more than the
6198 m68k chips in mod_status [Scott Anguish and Timothy Luoma
6201 *) [PORT] Recognize FreeBSD versions so we can use the OS regex as well
6202 as handling unsigned-chars for FreeBSD v3 and v2 [Andrey Chernov
6203 <ache@nagual.pp.ru> and Jim] PR#1450
6205 *) Use SA_RESETHAND or SA_ONESHOT when installing the coredump handlers.
6206 In particular the handlers could trigger themselves into an infinite
6207 loop if RLimitMem was used with a small amount of memory -- too small
6208 for the signal stack frame to be set up. [Dean Gaudet]
6210 *) Fix problems with absoluteURIs introduced during 1.3b4. [Dean Gaudet,

6217 [Charles Fu <ccwf@klab.caltech.edu>] PR#1847
6219 *) API: As Ken suggested the check_cmd_context() function and related
6220 defines are non-static now so modules can use 'em. [Martin Kraemer]
6222 *) mod_info would occasionally produce an unpaired <tt> in its
6223 output. Fixed. [Martin Kraemer]
6225 *) By default AIX binds a process (and it's children) to a single
6226 processor. httpd children now unbind themselves from that cpu
6227 and re-bind to one selected at random via bindprocessor()
6230 *) Linux 2.0 and above implement RLIMIT_AS, RLIMIT_DATA has almost no
6231 effect. Work around it by using RLIMIT_AS for the RLimitMEM
6232 directive. [Enrik Berkhan <enrik@inka.de>] PR#1816
6234 *) mod_mime_magic error message should indicate the filename when
6235 reads fail. ["M.D.Parker" <mdpc@netcom.com>] PR#1827
6237 *) Previously Apache would permit </Files> to end <FilesMatch> (and
6238 similary for Location and Directory), now this is diagnosed as an
6239 error. Improve error messages for mismatched sections (<Files>,
6240 <FilesMatch>, <Directory>, <DirectoryMatch>, ...).
6241 [Dean Gaudet, Martin Kraemer]
6243 *) <Files> is not permitted within <Location> (because of the
6244 semantic ordering). [Dean Gaudet] PR#379
6246 *) <Files> with wildcards was broken by the change in wildcard
6247 semantics (* does not match /). To fix this, <Files> now
6248 apply only to the basename of the request filename. This
6249 fixes some other inconsistencies in <Files> semantics
6250 (such as <Files a*b> not working). [Dean Gaudet] PR#1817

6257 *) Various errors from select() and accept() in child_main() would
6258 result in an infinite loop. It seems these two tickle kernel

6288 Changes with Apache 1.3b4
6290 *) The module structure was modified to include a *dynamic_load_handle
6291 in the STANDARD_MODULE_STUFF portion, and the MODULE_MAGIC_NUMBER
6292 has been bumped accordingly. [Paul Sutton]
6294 *) All BrowserMatch directives mentioned in
6295 htdocs/manual/known_client_problems.html are in the default
6296 configuration files. [Lars Eilebrecht]
6298 *) MiNT port update. [Jan Paul Schmidt]
6300 *) HTTP/1.1 requires x-gzip and gzip encodings be treated
6301 equivalent, similarly for x-compress and compress. Apache
6302 now ignores a leading x- when comparing encodings. It also
6303 preserves the encoding the client requests (for example if
6304 it requests x-gzip, then Apache will respond with x-gzip
6305 in the Content-Encoding header).
6306 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>] PR#1772
6308 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
6310 *) Added mod_so module to support dynamic loading of modules on Unix
6311 (like mod_dld for Win32). This replaces mod_dld.c. Use SharedModule
6312 instead of AddModule in Configuration to build shared modules
6313 [Sameer Parekh, Paul Sutton]
6315 *) Minor cleanups to r->finfo handling in some modules.
6318 *) Abstract read()/write() to ap_read()/ap_write().
6319 Makes it easier to add other types of IO code such as SFIO.
6322 *) API: Generalize default_port manipulations to make support of
6323 different protocols easier. [Ben Laurie, Randy Terbush]
6325 *) There are many cases where users do not want Apache to form
6326 self-referential urls using the "canonical" ServerName and Port.
6327 The new UseCanonicalName directive (default on), if set to off
6328 will cause Apache to use the client-supplied hostname and port.
6329 API: Part of this change required a change to the construct_url()

6333 PR#315, 459, 485, 1433
6335 *) Yet another rearrangement of the source tree.. now all the common
6336 header files are in the src/include directory. The -Imain -Iap
6337 references in Makefiles have been changed to the simpler -Iinclude
6338 instead. In addition to simplifying the build a little bit, this
6339 also makes it clear when a module is referencing something in a
6340 other than kosher manner (e.g., the proxy including mod_mime.h).
6341 Module-private header files (the proxy, mod_mime, the regex library,
6342 and mod_rewrite) have not been moved to src/include; nor have
6343 the OS-abstraction files. [Ken Coar]
6345 *) Fix a bug where r->hostname didn't have the :port stripped
6346 from it. [Dean Gaudet]
6348 *) Tweaked the headers_out table size, and the subprocess_env
6349 table size guess in rename_original_environment(). Added
6350 MAKE_TABLE_PROFILE which can help discover make_table()
6351 calls that use too small an initial guess, see alloc.c.
6354 *) Options and AllowOverride weren't properly merging in the main
6355 server setting inside vhosts (only an issue when you have no
6356 <Directory> or other section containing an Options that affects
6357 a request). Options +foo or -foo in the main_server wouldn't
6358 affect the main_server's lookup defaults. [Dean Gaudet]
6360 *) Variable 'cwd' was being used pointlessly before being set.
6363 *) r->allowed handling cleaned up in the standard modules.
6366 *) Some case-sensitivity issues cleaned up to be consistent with
6367 RFC2068. [Dean Gaudet]
6369 *) SIGURG doesn't exist everywhere.
6370 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6372 *) mod_unique_id was erroneously generating a second unique id when
6373 an internal redirect occured. Such redirects occur, for example,
6374 when processing a DirectoryIndex match. [Dean Gaudet]
6376 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6377 of the key and value. But in many cases this is not required
6378 because the key/value is a constant, or the value has been built
6379 by pstrcat() or other similar means. New routines table_addn,
6380 table_mergen, and table_setn have been added to the API, these
6381 routines do not pstrdup() their arguments. The core code and
6382 standard modules were changed to take advantage of these routines.
6383 The resulting server is up to 20% faster in some situations.
6385 Note that it is easy to get code subtly wrong if you pass a key/value
6386 which is in a pool other than the pool of the table. The only
6387 safe thing to do is to pass key/values which are in the pool of
6388 the table, or in one of the ancestors of the pool of the table.
6389 i.e. if the table is part of a subrequest, a value from the main
6390 request's pool is OK since the subrequest pool is a sub_pool of the
6391 main request's pool (and therefore has a lifespan at most as long as
6392 the main pool). There is debugging code which can detect improper
6393 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6394 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6396 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6397 which don't exist on disk more gracefully; handles vhosts properly.
6398 Update documentation to reflect the code -- if there's no
6399 MimeMagicFile directive then the module is not enabled.
6402 *) PORT: Some older *nix dialects cannot automatically start scripts
6403 which begin with a #! interpreter line (the shell starts the scripts
6404 appropriately on these platforms). Apache now supports starting of
6405 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6406 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6409 *) API: "typedef array_header table" removed from alloc.h, folks should
6410 have been writing to use table as if it were an opaque type, but even
6411 some standard modules got this wrong. By changing the definition
6412 to "typedef struct table table" module authors will receive compile
6413 time warnings that they're doing the wrong thing. This change
6414 facilitates future changes with more sophisticated table
6415 structures. Specifically, module authors should be using table_elts()
6416 to get access to an array_header * for the table. [Dean Gaudet]
6418 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6419 library routines. [Ken Coar, Rasmus Lerdorf]
6421 *) WIN32: mod_speling is now available on the Win32 platform.
6424 *) For clarity the following compile time definition was changed:
6426 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6428 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6429 and not be a general notice that the OS has mmap(). Now the
6430 HAVE_MMAP/SHMGET #defines strictly are informational that the
6431 OS has that method of shared memory; the type to use for
6432 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6433 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6434 determine if shared memory is available and allows Apache
6435 to determine the best method to use for the scoreboard.
6438 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6439 as do various earlier versions. It should be safe on all versions.

6464 The choice of flock vs. fcntl was made based on timings which showed that
6465 even on non-NFS, non-exported filesystems fcntl() was an order of
6466 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
6467 that single socket users will see no difference. [Dean Gaudet] PR#467

6914 *) PORT: Basic Gemini port (treat it like unixware212).
6915 ["Pavel Yakovlev (Paul McHacker)" <hac@tomcat.olly.ru>]
6917 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
6918 use USE_SHMGET_SCOREBOARD.
6921 *) Various improvements in detecting config file errors (missing closing
6922 directives for <Directory>, <Files> etc. blocks, prohibiting global
6923 server settings in <VirtualHost> blocks, flagging unhandled multiple
6924 arguments to <Directory>, <Files> etc.)
6927 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
6928 variable to provide this one to suexec'd CGIs, too.
6929 [M.D.Parker <mdpc@netcom.com>] PR#1284
6931 *) New support tool: src/support/split-logfile, a sample Perl script which
6932 splits up a combined access log into separate files based on the
6933 name of the virtual host (listed first in the log records by "%v").
6936 Changes with Apache 1.3b2 (there is no 1.3b1)
6938 *) TestCompile was not passing $LIBS [Dean Gaudet]
6940 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6943 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6944 rudimentary memory debugger which can be used on live servers with
6945 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6946 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6947 and free() for each object. This is far more expensive and should
6948 only be used for testing with tools such as Electric Fence and
6949 Purify. See main/alloc.c for more details. [Dean Gaudet]
6951 *) Configure uses a sh trap and didn't set its exitcode properly.
6952 [Dean Gaudet] PR#1159
6954 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6955 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6956 From a given ip:port, regardless what the Host: header is, you can
6957 only reach the vhosts defined on that ip:port. The precedence of
6958 vhosts was reversed to match other precedences in the config --
6959 the earlier vhosts override the later vhosts. All vhost matching was
6960 moved into http_vhost.[ch]. [Dean Gaudet]
6962 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6963 be used for whatever reason is appropriate (i.e. format() warnings
6964 for printf style functions). Both are enabled only with
6965 gcc >= 2.7.x (so that we have fewer support issues with older
6966 versions). [Dean Gaudet]
6968 *) Fix support for Proxy Authentication (we were testing the response
6969 status too early). [Marc Slemko]
6971 *) CoreDumpDirectory directive directs where the core file is
6972 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
6973 received. [Marc Slemko, Dean Gaudet]
6975 *) PORT: Support for Atari MINT.
6976 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
6978 *) When booting, apache will now detach itself from stdin, stdout,
6979 and stderr. stderr will not be detached until after the config
6980 files have been read so you will be able to see initial error
6981 messages. After that all errors are logged in the error_log.
6982 This makes it more convenient to start apache via rsh, ssh,
6983 or crontabs. [Dean Gaudet] PR#523
6985 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
6986 Also removed the auto-generated link to www.apache.org that was the
6987 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
6989 *) send_fb would not detect aborted connections in some situations.
6992 *) mod_include would use uninitialized data when parsing certain
6993 expressions involving && and ||. [Brian Slesinsky] PR#1139
6995 *) mod_imap should only handle GET methods. [Jay Bloodworth]
6997 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
6999 *) mod_autoindex improperly counted &escapes; as more than one
7000 character in the description. It also improperly truncated
7001 descriptions that were exactly the maximum length.
7004 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7005 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7008 *) mod_include now uses symbolic names to check for request success
7009 and return HTTP errors, and correctly handles all types of
7010 redirections (previously it only did temporary redirect correctly).
7011 [Ken Coar, Roy Fielding]
7013 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7014 r->filename. Since those two are meant to be in sync with each other
7015 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7017 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7018 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7020 *) Inetd mode (which is buggy) uses timeouts without having setup the
7021 jmpbuffer. [Dean Gaudet] PR#1064
7023 *) Work around problem under Linux where a child will start looping
7024 reporting a select error over and over.
7025 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7027 *) Fixed error in proxy_util.c when looping through multiple host IP
7028 addresses. [Lars Eilebrecht] PR#974
7030 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7031 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7032 bytes before writing, but it will never split a log entry across a
7033 buffer boundary. [Dean Gaudet]
7035 *) API: the short_score record has been split into two pieces, one which
7036 the parent writes on, and one which the child writes on. As part of
7037 this change the get_scoreboard_info() function was removed, and
7038 scoreboard_image was exported. This change fixes a race condition
7039 in file based scoreboard systems, and speeds up changes involving the
7040 scoreboard in earlier 1.3 development. [Dean Gaudet]
7042 *) API: New register_other_child() API (see http_main.h) which allows
7043 modules to register children with the parent for maintenance. It
7044 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7046 *) API: New piped_log API (see http_log.h) which implements piped logs,
7047 and will use register_other_child to implement reliable piped logs
7048 when it is available. The reliable piped logs part can be disabled
7049 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7050 logs is only available on Unix. [Dean Gaudet]
7052 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7053 meets_conditions(). This allows conditional HTTP selection to be
7054 handled separately from the storing of the header fields, and provides
7055 the ability for CGIs to set their own ETags for conditional checking.
7056 [Ken Coar, Roy Fielding] PR#895
7058 *) Changes to mod_log_config to allow naming of format strings.
7059 Format nicknames are defined with "LogFormat fmt nickname", and can
7060 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7063 *) New module, "mod_speling", which can help find files even when
7064 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7066 *) API: New function child_terminate() triggers the child process to
7067 exit, while allowing the child finish what it needs to for the
7068 current request first.
7069 [Doug MacEachern, Alexei Kosut]
7071 *) Windows now defaults to using full status reports with mod_status.
7072 [Alexei Kosut] PR #1094
7074 *) *Really* disable all mod_rewrite operations if the engine is off.
7075 Some things (like RewriteMaps) were checked/performed even if they
7076 weren't supposed to be. [Ken Coar] PR #991
7078 *) Implement a new timer scheme which eliminates the need to call alarm() all
7079 the time. Instead a counter in the scoreboard for each child is used to
7080 show when the child has made forward progress. The parent samples this
7081 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7082 progress has been made in the timeout period. This reduces the static
7083 request best-case syscall count to 22 from 29. This scheme is only
7084 used by systems with memory-based scoreboards. [Dean Gaudet]
7086 *) The proxy now properly handles CONNECT requests which are sent
7087 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7089 *) A script called apachectl has been added to the support
7090 directory. This script allows you to do things such as
7091 "apachectl start" and "apachectl restart" from the command
7094 *) Modules and core routines are now put into libraries, which
7095 simplifies the link line tremendously (among other advantages).
7098 *) Some of the MD5 names defined in Apache have been renamed to have
7099 an `ap_' prefix to avoid conflicts with routines supplied by
7100 external libraries. [Ken Coar]
7102 *) Removal of mod_auth_msql.c from the distribution. There are many
7103 other options for databases today. Rather than offer one option,
7104 offer none at this time. mod_auth_msql and other SQL database
7105 authentication modules can be found at the Apache Module Registry.
7106 http://modules.apache.org/ It would be nice to offer a generic
7107 mod_auth_sql option in the near future.
7109 *) PORT: BeOS support added [Alexei Kosut]
7111 *) Configure no longer accepts the -make option, since it creates
7112 Makefile on the fly based on Makefile.tmpl and Configuration.
7114 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7115 of forcibly killing off all its processes and exiting without
7116 cleaning up. [Alexei Kosut]
7118 *) API: A new field in the request_rec, r->mtime, has been added to
7119 avoid gratuitous parsing of date strings. It is intended to hold
7120 the last-modified date of the resource (if applicable). An
7121 update_mtime() routine has also been added to advance it if
7122 appropriate. [Roy Fielding, Ken Coar]
7124 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7125 deny access to the directory with a HTTP_FORBIDDEN. The previous
7126 behavior was to ignore the htaccess file if it could not be read.
7127 This change may make some setups with unreadable htaccess files
7128 stop working. [Marc Slemko] PR#817
7130 *) Add aplog_error() providing a mechanism to define levels of
7131 verbosity to the server error logging. This addition also provides
7132 the ability to log errors using syslogd. Error logging is configurable
7133 on a per-server basis using the LogLevel directive. Conversion
7134 of log_*() in progress. [Randy Terbush]
7136 *) Further enhance aplog_error() to not log filename, line number, and
7137 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7139 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7140 converted to long ones. Backslashes are converted to forward
7141 slashes. Case is converted to lower. Parts of URLs that do not
7142 correspond to files are left completely alone. [Ben Laurie]
7144 *) PORT: 2 new OSs added to the list of ports:
7145 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7146 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7148 *) Add the server version (SERVER_VERSION macro) to the "server
7149 configured and running" entry in the error_log. Also build an
7150 object file at link-time that contains the current time
7151 (SERVER_BUILT global const char[]), and include that in the
7154 *) Set r->headers_out when sending responses from the proxy.
7155 This fixes things such as the logging of headers sent from
7156 the proxy. [Marc Slemko] PR#659
7158 *) support/httpd_monitor is no longer distributed because the
7159 scoreboard should not be file based if at all possible. Use
7160 mod_status to see current server snapshot.
7162 *) (set_file_slot): New function, allowing auth directives to be
7163 independent of the server root, so the server documents can be
7164 moved to a different directory or machine more easily.
7165 [David J. MacKenzie]
7167 *) If no TransferLog is given explicitly, decline
7168 to log. This supports coexistence with other logging modules,
7169 such as the custom one that UUNET uses. [David J. MacKenzie]
7171 *) Check for titles in server-parsed HTML files.
7172 Ignore leading newlines and returns in titles. The old behavior
7173 of replacing a newline after <title> with a space causes the
7174 title to be misaligned in the listing. [David J. MacKenzie]
7176 *) Change mod_cern_meta to be configurable on a per-directory basis.
7177 [David J. MacKenzie]
7179 *) Add 'Include' directive to allow inclusion of configuration
7180 files within configuration files. [Randy Terbush]
7182 *) Proxy errors on connect() are logged to the error_log (nothing
7183 new); now they include the IP address and port that failed
7184 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7186 *) Various architectures now define USE_MMAP_FILES which causes
7187 the server to use mmap() for static files. There are two
7188 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7189 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7190 number of bytes written in one cycle from a single mmap()d object,
7191 default 32768). [Dean Gaudet]
7193 *) API: Added post_read_request API phase which is run right after reading
7194 the request from a client, or right after an internal redirect. It is
7195 useful for modules setting environment variables that depend only on
7196 the headers/contents of the request. It does not run during subrequests
7197 because subrequests inherit pretty much everything from the main
7198 request. [Dean Gaudet]
7200 *) Added mod_unique_id which is used to generate a unique identifier for
7201 each hit, available in the environment variable UNIQUE_ID.
7204 *) init_modules is now called after the error logs have been opened. This
7205 allows modules to emit information messages into the error logs.
7208 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7209 information for case where proxy module is not available. [Marc Slemko]
7211 *) PORT: Apache has need for mutexes to serialize its children around
7212 accept. In prior versions either fcntl file locking or flock file
7213 locking were used. The method is chosen by the definition of
7214 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7215 and FLOCK for flock(). New options have been added:
7216 - SYSVSEM to use System V style semaphores
7217 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7218 - USLOCK to use IRIX uslock
7219 Based on timing various techniques, the following changes were made
7221 - Linux 2.x uses flock instead of fcntl
7222 - Solaris 2.x uses pthreads
7223 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7224 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7225 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7226 Martijn Koster <m.koster@pobox.com>]
7228 *) PORT: The semantics of accept/select make it very desirable to use
7229 mutexes to serialize accept when multiple Listens are in use. But
7230 in the case where only a single socket is open it is sometimes
7231 redundant to serialize accept(). Not all unixes do a good job with
7232 potentially dozens of children blocked on accept() on the same
7233 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7234 the server will avoid serialization when listening on only one socket,
7235 and use serialization when listening on multiple sockets.
7236 [Dean Gaudet] PR#467
7238 *) Configure changes: TestLib replaced by TestCompile, which has
7239 some additional capability (such as doing a sanity check of
7240 the compiler and flags selected); the version of Solaris is now
7241 available via the #define value of SOLARIS2; IRIX n32bit libs
7242 now supported and selectable by new Configuration Rule: IRIXN32;
7243 We no longer default to -O2 optimization. [Jim Jagielski]
7245 *) Updated Configure: Configuration now uses AddModule to specify
7246 module source or binary file location, relative to src directory.
7247 Modules can be dropped into modules/extra, or in their own
7248 directory, and modules can come with a Makefile or Configure can
7249 create one. Modules can add compiler or library information to
7250 generated Makefiles. [Paul Sutton]
7252 *) Source core re-organisation: distributed modules are now in
7253 modules/standard. All other source code is in main. OS-specific
7254 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7256 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7259 *) Fix another long-standing bug in sub_req_lookup_file where it would
7260 happily skip past access checks on subdirectories looked up with
7261 relative paths. (It's used by mod_dir, mod_negotiation,
7262 and mod_include.) [Dean Gaudet]
7264 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7265 N is the number of <Directory> sections, and M is the number of
7266 components in the filename of an object.
7268 To achieve this optimization the following config changes were made:
7269 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7270 <Files>s, and <Location>s now treat a slash as a special
7271 character. For example "/home/*/public_html" previously would
7272 match "/home/a/andrew/public_html", now it only matches things
7273 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7274 - It's possible now to use [] wildcarding in <Directory>, <Files>
7276 - Regex <Directory>s are applied after all non-regex <Directory>s.
7280 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7281 and corrupted paths. [Dean Gaudet]
7283 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7284 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7285 be accessed now via backreferences $1..$9 in RewriteConds test-against
7286 strings in addition to RewriteRules subst string. Second the grouped
7287 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7288 via backreferences %1..%9 both in following RewriteCond test-against
7289 strings and RewriteRules subst string. This provides maximum flexibility
7290 through the use of backreferences.
7291 Additionally the rewriting engine was cleaned up by putting common
7292 code to the new expand_backrefs_inbuffer() function.
7293 [Ralf S. Engelschall]
7295 *) When merging the main server's <Directory> and <Location> sections into
7296 a vhost, put the main server's first and the vhost's second. Otherwise
7297 the vhost can't override the main server. [Dean Gaudet] PR#717
7299 *) The <Directory> code would merge and re-merge the same section after
7300 a match was found, possibly causing problems with some modules.
7303 *) ip-based vhosts are stored and queried using a hashing function, which
7304 has been shown to improve performance on servers with many ip-vhosts.
7305 Some other changes had to be made to accommodate this:
7306 - the * address for vhosts now behaves like _default_
7307 - the matching process now is:
7308 - match an ip-vhost directly via hash (possibly matches main
7310 - if that fails, just pretend it matched the main server
7311 - if so far only the main server has been matched, perform
7312 name-based lookups (ServerName, ServerAlias, ServerPath)
7313 *only on name-based vhosts*
7314 - if they fail, look for _default_ vhosts
7315 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7317 *) dbmmanage overhaul:
7318 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7319 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7320 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7321 - provide better seed for rand
7322 - prompt for password as per getpass(3) (turn off echo, read from
7324 - use "newstyle" crypt based on $Config{osname} ($^O)
7325 - will not add a user if already in database, use new `update' command
7327 - added `check' command to check a users' password
7328 - added `import' command to convert existing password text-files or
7329 dbm files exported with `view'
7330 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7333 *) Added psocket() which is a pool form of socket(), various places within
7334 the proxy weren't properly blocking alarms while registering the cleanup
7335 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7336 was a bug where the client socket was being close()d twice due a still
7337 registered cleanup. [Dean Gaudet]
7339 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7342 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7343 [Jason Venner <jason@idiom.com>] PR#667
7345 *) Enable ``=""'' for RewriteCond directives to match against
7346 the empty string. This is the preferred way instead of ``^$''.
7347 [Ralf S. Engelschall]
7349 *) Fixed an infinite loop in mod_imap for references above the server root
7350 [Dean Gaudet] PR#748
7352 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7353 SendBufferSize, so that the TCP window can be set appropriately
7354 for LFNs. [Phillip A. Prindeville]
7356 *) mod_browser has been replaced by the more general mod_setenvif
7357 (courtesy of Paul Sutton). BrowserMatch* directives are still
7358 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7359 UnSetEnvIfZero directives. [Ken Coar]
7361 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7362 order for remote_host to be set (for logging, or for the env var
7363 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7366 *) mod_access overhaul:
7367 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7368 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7369 - Critical path was sped up by pre-computing a few things at config time.
7370 - The undocumented syntax "allow user-agents" was removed,
7371 the replacement is "allow from env=foobar" combined with mod_browser.
7372 - When used with hostnames it now forces a double-reverse lookup
7373 no matter what the directory settings are. This double-reverse
7374 doesn't affect any of the other routines that use the remote
7375 hostname. In particular it's still passed to CGIs and the log
7376 without the double-reverse check. Related PR#860.
7379 *) When a large bwrite() occurs (larger than the internal buffer size),
7380 while there is already something in the buffer, apache will combine
7381 the large write and the buffer into a single writev(). (This is
7382 in anticipation of using mmap() for reading files.)
7385 *) In obscure cases where a partial socket write occurred while chunking,
7386 Apache would omit the chunk header/footer on the next block. Cleaned
7387 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7388 a bug where a long pause in DNS lookups could cause the last packet
7389 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7391 *) API: Added child_exit function to module structure. This is called
7392 once per "heavy-weight process" just before a server child exit()'s
7393 e.g. when max_requests_per_child is reached, etc.
7394 [Doug MacEachern, Dean Gaudet]
7396 *) mod_include cleanup showed that handle_else was being used to handle
7397 endif. It didn't cause problems, but it was cleaned up too.
7400 *) mod_cern_meta would attempt to find meta files for the directory itself
7401 in some cases, but not in others. It now avoids it in all cases.
7404 *) mod_mime_magic would core dump if there was a decompression error.
7405 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7407 *) PORT: some variants of DGUX require -lsocket -lnsl
7408 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7410 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7411 by the various fields (name, size, et cetera), either in ascending
7412 or descending order. Just click on the column header. [Ken Coar]
7414 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7415 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7416 the relatively safe direction. [Dean Gaudet] PR#344
7418 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7419 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7421 *) child_main avoids an unneeded call to select() when there is only one
7422 listening socket. [Dean Gaudet]
7424 *) In the event that the server is starved for idle servers it will
7425 spawn 1, then 2, then 4, ..., then 32 servers each second,
7426 doubling each second. It'll also give a warning in the errorlog
7427 since the most common reason for this is a poor StartServers
7428 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7429 the maximum. [Dean Gaudet]
7431 *) Apache now provides an effectively unbuffered connection for
7432 CGI scripts. This means that data will be sent to the client
7433 as soon as the CGI pauses or stops output; previously, Apache would
7434 buffer the output up to a fixed buffer size before sending, which
7435 could result in the user viewing an empty page until the CGI finished
7436 or output a complete buffer. It is no longer necessary to use an
7437 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7438 in a language that by default does buffering (e.g. perl) this
7439 shouldn't have a detrimental effect on performance.
7441 "nph-" CGIs, which formerly provided a direct socket to the client
7442 without any server post-processing, were not fully compatible with
7443 HTTP/1.1 or SSL support. As such they would have had to implement
7444 the transport details, such as encryption or chunking, in order
7445 to work properly in certain situations. Now, the only difference
7446 between nph and non-nph scripts is "non-parsed headers".

7449 *) If a BUFF is switched from buffered to unbuffered reading the first
7450 bread() will return whatever remained in the buffer prior to the
7451 switch. [Dean Gaudet]
7453 Changes with Apache 1.3a1
7455 *) Added another Configure helper script: TestLib. It determines
7456 if a specified library exists. [Jim Jagielski]
7458 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7459 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7462 *) PORT: Some architectures use size_t for various lengths in network
7463 functions such as accept(), and getsockname(). The definition
7464 NET_SIZE_T is used to control this. [Dean Gaudet]
7466 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7467 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7468 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7470 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7471 [Igor N Kovalenko <infoh@mail.wplus.net>]
7473 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7474 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7475 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7476 [Dean Gaudet] related PR#875
7478 *) API: Correct child_init() slot declaration from int to void, to
7479 match the init() declaration. Update mod_example to use the new
7482 *) added transport handle slot (t_handle) to the BUFF structure
7485 *) get_client_block() returns wrong length if policy is

7493 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
7494 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
7496 *) AddModuleInfo directive for mod_info which allows you to annotate
7497 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7499 *) Added NoProxy directive to avoid using ProxyRemote for selected
7500 addresses. Added ProxyDomain directive to cause unqualified
7501 names to be qualified by redirection.
7502 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7504 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7505 header to the remote host in the proxy. [Sameer Parekh and
7508 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7509 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7510 URLs, fixed rewritelog(), fixed forced response code handling on
7511 redirects from within .htaccess files, disabled pipe locking under
7512 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7513 no substitution, bugfixed situations where HostnameLookups is off, made
7514 mod_rewrite more thread-safe for NT port and fixed problem when creating
7515 an empty query string via "xxx?".
7516 This update also removes the copyright of Ralf S. Engelschall,
7517 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7518 exclusively copyrighted by the Apache Group now. This happened because
7519 the author now has gifted mod_rewrite exclusively to the Apache Group and
7520 no longer maintains an external version.
7521 [Ralf S. Engelschall]
7523 *) API: Added child_init function to module structure. This is called
7524 once per "heavy-weight process" before any requests are handled.
7525 See http_config.h for more details. [Dean Gaudet]
7527 *) Anonymous_LogEmail was logging on each subrequest.
7528 [Dean Gaudet] PR#421, 868
7530 *) API: Added is_initial_req() which tests if the request being
7531 processed is the initial request, or a subrequest.
7534 *) Extended SSI (mod_include) now handles additional relops for
7535 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7537 *) Configure fixed to correctly propagate user-selected options and
7538 settings (such as CC and OPTIM) to Makefiles other than
7539 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7541 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7542 directory indices to start with the contents of the HeaderName file
7543 if there is one. If there isn't one, the behaviour is unchanged.
7544 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7546 *) WIN32: Modules can now be dynamically loaded DLLs using the
7547 LoadModule/LoadFile directives. Note that module DLLs must be
7548 compiled with the multithreaded DLL version of the runtime library.
7549 [Alexei Kosut and Ben Laurie]
7551 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7552 This allows the admin to completely remove automatic indexing
7553 from the server, while still supporting the basic functions of
7554 trailing-slash redirects and DirectoryIndex files. Note that if
7555 you're carrying over an old Configuration file and you use directory
7556 indexing then you'll want to add:
7558 Module autoindex_module mod_autoindex.o
7560 before mod_dir in your Configuration. [Dean Gaudet]
7562 *) popendir/pclosedir created to properly protect directory scanning.
7563 [Dean Gaudet] PR#525
7565 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7566 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7567 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7570 *) The AccessFileName directive can now take more than one filename.
7571 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7573 *) The new mod_mime_magic can be used to "magically" determine the type
7574 of a file if the extension is unknown. Based on the unix file(1)
7575 command. [Ian Kluft <ikluft@cisco.com>]
7577 *) We now determine and display the time spent processing a
7578 request if desired. [Jim Jagielski]
7580 *) mod_status: PID field of "dead" child slots no longer displays
7581 main httpd process's PID. [Jim Jagielski]
7583 *) Makefile.nt added - to build all the bits from the command line:
7584 nmake -f Makefile.nt
7585 Doesn't yet work properly. [Ben Laurie]
7587 *) Default text of 404 error is now "Not Found" rather than the
7588 potentially misleading "File Not Found". [Ken Coar]
7590 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7591 for the net if we require people that actually need this data to
7592 enable it. [Linus Torvalds]
7594 *) directory_walk() is an expensive function, keep a little more state to
7595 avoid needless string counting. Add two new functions make_dirstr_parent
7596 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7597 The new functions are a little less general than make_dirstr, but
7598 work more efficiently (less memory, less string counting).
7601 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7602 to LDFLAGS) to avoid complications with lex rules in make files.
7603 [Dean Gaudet] PR#372
7605 *) run_method optimized to avoid needless scanning over NULLs in the
7606 module list. [Dean Gaudet]
7608 *) Revamp of (unix) scoreboard management code such that it avoids
7609 unnecessary traversals of the scoreboard on each hit. This is
7610 particularly important for high volume sites with a large
7611 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7612 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7613 httpd.h. [Dean Gaudet]
7615 *) In configurations using multiple Listen statements it was possible for
7616 busy sockets to starve other sockets of service. [Dean Gaudet]
7618 *) Added hook so standalone_main can be replaced at compile time
7619 (define STANDALONE_MAIN)
7622 *) Lowest-level read/write functions in buff.c will be replaced with
7623 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7624 compile time. The default sfio discipline will behave as apache
7625 would without sfio compiled in.
7628 *) Enhance UserDir directive (mod_userdir) to accept a list of
7629 usernames for the 'disable' keyword, and add 'enable user...' to
7630 selectively *en*able userdirs if they're globally disabled.
7633 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7634 will work with Netscape dbm files. (dbmmanage will probably not
7635 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7637 *) Add a ListenBacklog directive to control the backlog parameter
7638 passed to listen(). Also change the default to 511 from 512.
7641 *) API: A new handler response DONE which informs apache that the
7642 request has been handled and it can finish off quickly, similar to
7643 how it handles errors. [Rob Hartill]
7645 *) Turn off chunked encoding after sending terminating chunk/footer
7646 so that we can't do it twice by accident. [Roy Fielding]
7648 *) mod_expire also issues Cache-Control: max-age headers.
7651 *) API: Added kill_only_once option for free_proc_chain so that it won't
7652 aggressively try to kill off specific children. For fastcgi.
7653 [Stanley Gambarin <gambarin@OpenMarket.com>]
7655 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7657 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7658 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7659 attributes in the FancyIndexing IMG tags. [Ken Coar]
7661 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7663 *) PORT: Added Windows NT support
7664 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7666 Changes with Apache 1.2.6
7668 *) mod_include when using XBitHack Full would send ETags in addition to
7669 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7670 [Dean Gaudet] PR#1133
7672 *) SECURITY: When a client connects to a particular port/addr, and
7673 gives a Host: header ensure that the virtual host requested can
7674 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7676 *) Support virtual hosts with wildcard port and/or multiple ports
7677 properly. [Ed Korthof <ed@organic.com>]
7679 *) Fixed some case-sensitivity issues according to RFC2068.
7682 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7683 and mod_include.c. [Dean Gaudet]
7685 *) Variable 'cwd' was being used pointlessly before being set.
7688 *) SIGURG doesn't exist on all platforms.
7689 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7691 *) When an error occurs during a POST, or other operation with a
7692 request body, the body has to be read from the net before allowing
7693 a keepalive session to continue. [Roy Fielding] PR#1399
7695 *) When an error occurs in fcntl() locking suggest the user look up
7696 the docs for LockFile. [Dean Gaudet]
7698 *) table_set() and table_unset() did not deal correctly with
7699 multiple occurrences of the same key. [Stephen Scheck
7700 <sscheck@infonex.net>, Ben Laurie] PR#1604
7702 *) send_fd_length() did not calculate total_bytes_sent properly in error
7703 cases. [Ben Reser <breser@regnow.com>] PR#1366
7705 *) r->connection->user was allocated in the wrong pool causing corruption
7706 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7708 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7709 Also removed the auto-generated link to www.apache.org that was the
7710 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7712 *) Multiple "close" tokens may have been set in the "Connection"
7713 header, not an error, but a waste.
7714 [Ronald.Tschalaer@psi.ch] PR#1683
7716 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7717 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7719 *) It appears the "257th byte" bug (see
7720 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7721 at the 256th byte as well. Fixed. [Dean Gaudet]
7723 *) mod_rewrite would not handle %3f properly in some situations.
7726 *) Apache could generate improperly chunked HTTP/1.1 responses when
7727 the bputc() or rputc() functions were used by modules (such as
7728 mod_include). [Dean Gaudet]
7730 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7731 some ports. [Ralf Engelschall]
7733 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7735 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7737 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7739 Changes with Apache 1.2.5
7741 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7742 only an issue on systems without a MAXDNAME define or where
7743 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7745 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7748 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7749 directory listings. [Marc Slemko]
7751 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7754 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7755 is used to read various types of files such as htaccess and
7756 htpasswd files. [Marc Slemko]
7758 *) SECURITY: Ensure that the buffer returned by ht_time is always
7759 properly null terminated. [Marc Slemko]
7761 *) SECURITY: General mod_include cleanup, including fixing several
7762 possible buffer overflows and a possible infinite loop. This cleanup
7763 was done against 1.3 code and then backported to 1.2, the result
7764 is a large difference (due to indentation cleanup in 1.3 code).
7765 Users interested in seeing a smaller set of relevant differences
7766 should consider comparing against src/modules/standard/mod_include.c
7767 from the 1.3b3 release. Non-indentation changes to mod_include
7768 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7770 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7771 including fixing a possible buffer overflow. This cleanup also
7772 was done with 1.3 code as a basis, see the the previous note
7773 about mod_include. [Dean Gaudet]
7775 *) SECURITY: If a htaccess file can not be read due to bad
7776 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7777 The previous behavior was to ignore the htaccess file if it could not
7778 be read. This change may make some setups with unreadable
7779 htaccess files stop working. PR#817 [Marc Slemko]
7781 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7782 Make it O(n). This inefficiency could be used to mount a denial
7783 of service attack against the Apache server. Thanks to
7784 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting

7809 Changes with Apache 1.2.4
7811 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7812 always making requests with the full-URI instead of just the URI path.
7813 [Marc Slemko, Roy Fielding]
7815 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7816 on this platform. [Marc Slemko]
7818 Changes with Apache 1.2.3
7820 *) The request to a remote proxy was mangled if it was generated as the
7821 result of a ProxyPass directive. URL schemes other than http:// were not
7822 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,

7833 Changes with Apache 1.2.2 [not released]
7835 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7836 happily skip past access checks on subdirectories looked up with relative
7837 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7840 *) Add lockfile name to error message printed out when
7841 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7844 *) Enhanced the chunking and error handling inside the buffer functions.

7848 a vhost, put the main server's first and the vhost's second. Otherwise
7849 the vhost can't override the main server. [Dean Gaudet] PR#717
7851 *) The <Directory> code would merge and re-merge the same section after
7852 a match was found, possibly causing problems with some modules.

7856 [Dean Gaudet] PR#748
7858 *) mod_include cleanup showed that handle_else was being used to handle
7859 endif. It didn't cause problems, but it was cleaned up too.
7862 *) Last official synchronization of mod_rewrite with author version (because
7863 mod_rewrite is now directly developed by the author at the Apache Group):
7864 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7865 minus WIN32/NT stuff, but plus copyright removement.

7874 o remove static from local data and add static to global ones.
7875 o replaced ugly proxy finding stuff by simple
7876 find_linked_module("mod_proxy") call.

7909 *) API: In HTTP/1.1, whether or not a request message contains a body
7910 is independent of the request method and based solely on the presence

7964 *) Attempt to work around problems with third party libraries that do not
7965 handle high numbered descriptors (examples include bind, and
7966 solaris libc). On all systems apache attempts to keep all permanent
7967 descriptors above 15 (called the low slack line). Solaris users
7968 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7969 which keeps all non-FILE * descriptors above 255. On all systems
7970 this should make supporting large numbers of vhosts with many open
7971 log files more feasible. If this causes trouble please report it,
7972 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7973 [Dean Gaudet] various PRs
7975 *) Related to the last entry, network sockets are now opened before
7976 log files are opened. The only known case where this can cause
7977 problems is under Solaris with many virtualhosts and many Listen
7978 directives. But using -DHIGH_SLACK_LINE=256 described above will
7979 work around this problem. [Dean Gaudet]
7981 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
7984 *) Improved unix error response logging. [Marc Slemko]
7986 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
7987 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
7988 when a URL http://... was used in conjunction with a special
7989 redirect flag, e.g. R=permanent, the permanent status was lost.

8030 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
8031 [Doug MacEachern, Rob Hartill]
8033 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
8034 reading from one buffer and writing to another, at least until it has
8035 a custom timeout handler. [Roy Fielding and Petr Lampa]

8045 *) Virtual hosts with the same ServerName, but on different ports, were
8046 not being selected properly. [Ed Korthof]
8048 *) Added code to return the requested IP address from proxy_host2addr()
8049 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
8050 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8051 [Chuck Murcko] PR#614
8053 *) If multiple requests on a single connection are used to retrieve
8054 data from different virtual hosts, the virtual host list would be
8055 scanned starting with the most recently used VH instead of the first,
8056 causing most virtual hosts to be ignored.

8059 *) The OS/2 handling of process group was broken by a porting patch for
8060 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]

8070 *) If a soft_timeout occurs after keepalive is set, then the main child
8071 loop would try to read another request even though the connection
8072 has been aborted. [Roy Fielding]
8074 *) Configure changes: Allow for whitespace at the start of a
8075 Module declaration. Also, be more understanding about the
8076 CC=/OPTIM= format in Configuration. Finally, fix compiler
8077 flags if using HP-UX's cc compiler. [Jim Jagielski]
8079 *) Subrequests and internal redirects now inherit the_request from the
8080 original request-line. [Roy Fielding]
8082 *) Test for error conditions before creating output header fields, since
8083 we don't want the error message to include those fields. Likewise,
8084 reset the content_language(s) and content_encoding of the response
8085 before generating or redirecting to an error message, since the new
8086 message will have its own Content-* definitions. [Dean Gaudet]
8088 *) Restored the semantics of headers_out (headers sent only with 200..299
8089 and 304 responses) and err_headers_out (headers sent with all responses).
8090 Avoid the overhead of copying tables if err_headers_out is empty
8091 (the usual case). [Roy Fielding]
8093 *) Fixed a couple places where a check for the default Content-Type was
8094 not properly checking both the value configured by the DefaultType
8095 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8096 of DEFAULT_TYPE to match the documented default (text/plain).
8097 [Dean Gaudet] PR#506
8099 *) Escape the HTML-sensitive characters in the Request-URI that is
8100 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8102 *) Properly initialize the flock structures used by the mutex locking
8103 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8106 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8107 (and NCSA httpd) definition wherein it was the extra path info beyond
8108 the CGI script filename. The environment variable FILEPATH_INFO has
8109 been removed, and instead we supply the original REQUEST_URI to any
8110 script that wants to be Apache-specific and needs the real URI path.
8111 This solves a problem with existing scripts that use extra path info
8112 in the ScriptAlias directive to pass options to the CGI script.
8115 *) The _default_ change in 1.2b10 will change the behaviour on configs
8116 that use multiple Listen statements for listening on multiple ports.
8117 But that change is necessary to make _default_ consistent with other
8118 forms of <VirtualHost>. It requires such configs to be modified
8119 to use <VirtualHost _default_:*>. The documentation has been
8120 updated. [Dean Gaudet] PR#530
8122 *) If an ErrorDocument CGI script is used to respond to an error
8123 generated by another CGI script which has already read the message
8124 body of the request, the server would block trying to read the
8125 message body again. [Rob Hartill]

8128 other platforms). Fixed. [Ben Laurie] PR#512

8148 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8149 changes and in anticipation of 1.2 final release. [Roy Fielding]
8151 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8152 the connection (e.g., when user presses Stop). Apache will now stop
8153 trying to send a message body immediately after an error from write.
8154 [Roy Fielding and Nathan Kurz] PR#335
8156 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8157 than mod_alias, and mod_alias has higher priority than mod_proxy;
8158 rearranged other modules to enhance understanding of their purpose
8159 and relative order (and maybe even reduce some overhead).
8160 [Roy Fielding and Sameer Parekh]
8162 *) Fix graceful restart. Eliminate many signal-related race
8163 conditions in both forms of restart, and in SIGTERM. See
8164 htdocs/manual/stopping.html for details on stopping and
8165 restarting the parent. [Dean Gaudet]
8167 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8168 memory allocator to avoid a behaviour that required extra blocks to
8169 be allocated. [Dean Gaudet]
8171 *) Allow suexec to access files relative to current directory but not
8172 above. (Excluding leading / or any .. directory.) [Ken Coar]
8175 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8176 PR#367, 368, 354, 453
8178 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8179 while obtaining the /~user and save the username in a separate data
8180 area so that it won't be overwritten by the call to getgrgid(), and
8181 fix some misuse of the pool string allocation functions. Also fixes
8182 a general problem with parsing URL query info into args for CGI scripts.

8190 AuthDBAuthoritative. [Marc Slemko] PR#420
8192 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8194 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8195 object that can't be PUT, or FOOBAR for some method FOOBAR that
8196 apache doesn't know about at all). Log 404s that occur in mod_include.
8197 [Paul Sutton, John Van Essen]
8199 *) If a soft timeout (or lingerout) occurs while trying to flush a
8200 buffer or write inside buff.c or fread'ing from a CGI's output,
8201 then the timeout would be ignored. [Roy Fielding] PR#373
8203 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8204 parsing of headers. If the terminating empty-line CRLF occurs starting
8205 at the 256th or 257th byte of output, then Navigator will think a normal
8206 image is invalid. We are guessing that this is because their initial
8207 read of a new request uses a 256 byte buffer. We check the bytes written
8208 so far and, if we are about to tickle the bug, we instead insert a
8209 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8211 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8212 of an external redirection. [Roy Fielding and Paul Sutton]
8214 *) Configure would create a broken Makefile if the configuration file
8215 contained a commented-out Rule. [Roy Fielding]
8217 *) Promote per_dir_config and subprocess_env from the subrequest to the
8218 main request in mod_negotiation. In particular this fixes a bug
8219 where <Files> sections wouldn't properly apply to negotiated content.
8222 *) Fix a potential deadlock in mod_cgi script_err handling.
8223 [Ralf S. Engelschall]
8225 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8228 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8229 .htaccess files because the RewriteBase was not replaced correctly.
8230 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8231 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8233 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8234 1.x the settings are those of pre-1.2b8. For 2.x we include
8235 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8236 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8237 [Dean Gaudet] PR#336, PR#340
8239 *) Redirect did not preserve ?query_strings when present in the client's
8240 request. [Dean Gaudet]

8244 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8246 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8248 *) Add mod_example (illustration of API techniques). [Ken Coar]
8250 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8252 *) Improve handling of directories when filenames have spaces in them.
8255 *) For hosts with multiple IP addresses, try all additional addresses if
8256 necessary to get a connect. Fail only if hostent address list is
8257 exhausted. [Chuck Murcko]
8259 *) More signed/unsigned port fixes. [Dean Gaudet]
8261 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8264 Changes with Apache 1.2b8
8266 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8267 to it. [Marc Slemko]
8269 *) The addition of <Location> and <File> directives made the
8270 sub_req_lookup_simple() function bogus, so we now handle
8271 the special cases directly. [Dean Gaudet]
8273 *) We now try to log where the server is dumping core when a fatal
8274 signal is received. [Ken Coar]
8276 *) Improved lingering_close by adding a special timeout, removing the
8277 spurious log messages, removing the nonblocking settings (they
8278 are not needed with the better timeout), and adding commentary
8279 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8280 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8282 *) Send error messages about setsockopt failures to the server error
8283 log instead of stderr. [Roy Fielding]
8285 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8287 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8288 processing a subrequest, allocate memory from r->main->pool instead
8289 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8290 in the middle of an SSI request. [Dean Gaudet] PR #122
8292 *) Fixed status of response when POST is received for a nonexistent URL
8293 (was sending 405, now 404) and when any method is sent with a
8294 full-URI that doesn't match the server and the server is not acting
8295 as a proxy (was sending 501, now 403). [Roy Fielding]
8297 *) Host port changed to unsigned short. [Ken Coar] PR #276
8299 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8301 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8303 *) Report extra info from errno with many errors that cause httpd to exit.
8304 spawn_child, popenf, and pclosef now have valid errno returns in the
8305 event of an error. Correct problems where errno was stomped on
8306 before being reported. [Dean Gaudet]
8308 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8309 never called, and thus the filesystem would remain full indefinitely.
8310 We now also remove incomplete cache files left if the origin server
8311 didn't send a Content-Length header and either the client has aborted
8312 transfer or bwrite() to client has failed. [Petr Lampa]
8314 *) Fixed the handling of module and script-added header fields.
8315 Improved the interface for sending header fields and reduced
8316 the duplication of code between sending okay responses and errors.
8317 We now always send both headers_out and err_headers_out, and
8318 ensure that the server-reserved fields are not being overridden,
8319 while not overriding those that are not reserved. [Roy Fielding]
8321 *) Moved transparent content negotiation fields to err_headers_out
8322 to reflect above changes. [Petr Lampa]
8324 *) Fixed the determination of whether or not we should make the
8325 connection persistent for all of the cases where some other part
8326 of the server has already indicated that we should not. Also
8327 improved the ordering of the test so that chunked encoding will
8328 be set whenever it is desired instead of only when KeepAlive
8329 is enabled. Added persistent connection capability for most error
8330 responses (those that do not indicate a bad input stream) when
8331 accessed by an HTTP/1.1 client. [Roy Fielding]
8333 *) Added missing timeouts for sending header fields, error responses,
8334 and the last chunk of chunked encoding, each of which could have
8335 resulted in a process being stuck in write forever. Using soft_timeout
8336 requires that the sender check for an aborted connection rather than
8337 continuing after an EINTR. Timeouts that used to be initiated before
8338 send_http_header (and never killed) are now initiated only within or
8339 around the routines that actually do the sending, and not allowed to
8340 propagate above the caller. [Roy Fielding]
8342 *) mod_auth_anon required an @ or a . in the email address, not both.
8345 *) per_dir_defaults weren't set correctly until directory_walk for
8346 name-based vhosts. This fixes an obscure bug with the wrong config
8347 info being used for vhosts that share the same ip as the server.
8350 *) Improved generation of modules/Makefile to be more generic for
8351 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8353 *) Generate makefile dependency for Configuration based on the actual
8354 name given when running the Configure process. [Dean Gaudet]
8356 *) Fixed problem with vhost error log not being set prior to
8357 initializing virtual hosts. [Dean Gaudet]
8359 *) Fixed infinite loop when a trailing slash is included after a type map
8360 file URL (extra path info). [Petr Lampa]
8362 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8364 *) Add documentation for DNS issues (reliability and security), and try
8365 to explain the virtual host matching process. [Dean Gaudet]
8367 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8368 fails while parsing the configuration file. [Dean Gaudet]
8370 *) Improved calls to setsockopt. [Roy Fielding]
8372 *) Negotiation changes: Don't output empty content-type in variant list;
8373 Output charset in variant list; Return sooner from handle_multi() if
8374 no variants found; Add handling of '*' wildcard in Accept-Charset.
8375 [Petr Lampa and Paul Sutton]
8377 *) Fixed overlaying of request/sub-request notes and headers in
8378 mod_negotiation. [Dean Gaudet]
8380 *) If two variants' charset quality are equal and one is the default
8381 charset (iso-8859-1), then prefer the variant that was specifically
8382 listed in Accept-Charset instead of the default. [Petr Lampa]
8384 *) Memory allocation problem in push_array() -- it would corrupt memory
8385 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8387 *) invoke_handler() doesn't handle mime arguments in content-type
8390 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8393 *) Fixed problem with ErrorDocument not working for virtual hosts
8394 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8396 *) Log an error message if we get a request header that is too long,
8397 since it may indicate a buffer overflow attack. [Marc Slemko]
8399 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8400 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8401 [Ken Coar] PR #146, #187
8403 *) Added table entry placeholder for new header_parser callback
8404 in all of the distributed modules. [Ken Coar] PR #191

8407 [Garey Smiley] PR #59
8409 *) Fixed error message when resource is not found and URL contains
8410 path info. [Petr Lampa and Dean Gaudet] PR #40
8412 *) Fixed user and server confusion over what should be a virtual host
8413 and what is the main server, resulting in access to something
8414 other than the name defined in the virtualhost directive (but
8415 with the same IP address) failing. [Dean Gaudet]
8417 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8418 AIX; improves the redirection stuff to enable the users to generally
8419 redirect to http, https, gopher and ftp; added TIME variable for
8420 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8421 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8422 can be used in conjunction with %{TIME} or other variables to create
8423 time-dependent rewriting rules. [Ralf S. Engelschall]
8425 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8426 Module authors may need to adjust their code for proper cleanup to take
8427 place (that is, call note_cleanups_for_fd()). This change fixes problems
8428 with file descriptors being erroneously closed when the proxy module was
8429 in use. [Ben Laurie]
8431 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8432 initgroups() to hose the group information needed for later
8433 comparisons. [Randy Terbush]
8435 *) Remove unnecessary call to va_end() in create_argv() which
8436 caused a SEGV on some systems.
8438 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8441 *) Clear memory allocated for listeners. [Randy Terbush]
8443 *) Improved handling of IP address as a virtualhost address and
8444 introduced "_default_" as a synonym for the default vhost config.

8463 *) more proxy FTP bug fixes:
8464 - Changed send_dir() to remove user/passwd from displayed URL.
8465 - Changed login error messages to be more descriptive.
8466 - remove setting of SO_DEBUG socket option
8467 - Make ftp_getrc() more lenient about multiline responses,
8468 specifically, 230 responses which don't have continuation 230-
8469 on each line). These seem to be all NT FTP servers, and while
8470 perhaps questionable, they appear to be legal by RFC 959.
8471 - Add missing kill_timeout() after transfer to user completes.
8474 *) Fixed problem where a busy server could hang when restarting
8475 after being sent a SIGHUP due to child processes not exiting.
8478 *) Modify mod_include escaping so a '\' only signifies an escaped

8500 the socket is not connected (reset by client). [Roy Fielding]
8502 *) Rearranged main child loop to remove duplication of code in
8503 select/accept and keep-alive requests, fixed several bugs regarding
8504 checking scoreboard_image for exit indication and failure to
8505 account for all success conditions and trap all error conditions,
8506 prevented multiple flushes before closing the socket; close the entire
8507 socket buffer instead of just one descriptor, prevent logging of
8508 EPROTO and ECONNABORTED on platforms where supported, and generally
8509 improved readability. [Roy Fielding]
8511 *) Extensive performance improvements. Cleaned up inefficient use of
8512 auto initializers, multiple is_matchexp calls on a static string,
8513 and excessive merging of response_code_strings. [Dean Gaudet]
8515 *) Added double-buffering to mod_include to improve performance on
8516 server-side includes. [Marc Slemko]
8518 *) Several fixes for suexec wrapper. [Randy Terbush]
8519 - Make wrapper work for files on NFS filesystem.
8520 - Fix portability problem of MAXPATHLEN.
8521 - Fix array overrun problem in clean_env().
8522 - Fix allocation of PATH environment variable
8524 *) Removed extraneous blank line is description of mod_status chars.
8527 *) Logging of errors from the call_exec routine simply went nowhere,
8528 since the logfile fd has been closed, so now we send them to stderr.
8529 [Harald T. Alvestrand]
8531 *) Fixed core dump when DocumentRoot is a CGI.
8532 [Ben Laurie, reported by geddis@tesserae.com]
8534 *) Fixed potential file descriptor leak in mod_asis; updated it and
8535 http_core to use pfopen/pfclose instead of fopen/fclose.
8536 [Randy Terbush and Roy Fielding]
8538 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8539 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8540 [Dean Gaudet and Ken Coar]
8542 *) Return a 302 response code to the client when sending a redirect
8543 due to a missing trailing '/' on a directory instead of a 301; now
8544 it is cacheable. [Markus Gyger]
8546 *) Fix condition where, if a bad directive occurs in .htaccess, and
8547 sub_request() goes first to this directory, then log_reason() will
8548 SIGSEGV because it doesn't have initialized r->per_dir_config.
8549 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8551 *) Fix handling of lang_index in is_variant_better(). This was
8552 causing problems which resulted in the server sending the
8553 wrong language document in some cases. [Petr Lampa]
8555 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8556 the clean environment on some systems.
8558 *) Tweak byteserving code (e.g. serving PDF files) to work around
8559 bugs in Netscape Navigator and Microsoft Internet Explorer.
8560 Emit Content-Length header when sending multipart/byteranges.
8563 *) Port to HI-UX/WE2. [Nick Maclaren]
8565 *) Port to HP MPE operating system for HP 3000 machines
8566 [Mark Bixby <markb@cccd.edu>]
8568 *) Fixed bug which caused a segmentation fault if only one argument
8569 given to RLimit* directives. [Ed Korthof]
8571 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8573 *) Improved buffered output to the client by delaying the flush decision
8574 until the BUFF code is actually about to read the next request.
8575 This fixes a problem introduced in 1.2b5 with clients that send
8576 an extra CRLF after a POST request. Also improved chunked output
8577 performance by combining writes using writev() and removing as
8578 many bflush() calls as possible. NOTE: Platforms without writev()
8579 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8580 or Configure, unless we have already done so. [Dean Gaudet]
8582 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8584 *) Fixed mod_info output corruption bug introduced by buffer overflow
8585 fixes. [Dean Gaudet]
8587 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8588 for the special case of a 304 response. [Paul Sutton]
8590 *) Improved handling of TRACE method by bypassing normal method handling
8591 and header parsing routines; fixed Allow response to always allow TRACE.
8594 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8596 *) Cleaned-up some of the generated HTML. [Ken Coar]
8598 Changes with Apache 1.2b6
8600 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8602 *) Fix typo introduced in fix for potential infinite loop around
8603 accept() in child_main(). This change caused the rev to 1.2b6.
8604 1.2b5 was never a public beta.
8606 Changes with Apache 1.2b5
8608 *) Change KeepAlive semantics (On|Off instead of a number), add
8609 MaxKeepAliveRequests directive. [Alexei Kosut]
8611 *) Various NeXT compilation patches, as well as a change in
8612 regex/regcomp.c since that file also used a NEXT define.
8615 *) Allow * to terminate the end of a directory match in mod_dir.
8616 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8618 *) Don't call can_exec() if suexec_enabled. Calling this requires
8619 scripts executed by the suexec wrapper to be world executable, which
8620 defeats one of the advantages of running the wrapper. [Randy Terbush]
8622 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8625 *) Migration from sprintf() to snprintf() to avoid buffer
8626 overflows. [Marc Slemko]
8628 *) Provide portable snprintf() implementation (ap_snprintf)
8629 as well as *cvt family. [Jim Jagielski]
8631 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8634 *) Remove mod_fastcgi.c from the distribution. This module appears
8635 to be maintained more through the Open Market channels and should
8636 continue to be easily available at http://www.fastcgi.com/
8638 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8639 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8641 *) mod_info assumed that the config files were relative to ServerRoot.
8644 *) CGI scripts called as an error document resulting from failed
8645 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8647 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8650 *) Properly check errno to prevent display of a directory index
8651 when server receives a long enough URL to confuse stat().
8654 *) Several security enhancements to suexec wrapper. It is _highly_
8655 recommended that previously installed versions of the wrapper
8656 be replaced with this version. [Randy Terbush, Jason Dour]
8658 - ~user execution now properly restricted to ~user's home
8659 directory and below.
8660 - execution restricted to UID/GID > 100
8661 - restrict passed environment to known variables
8662 - call setgid() before initgroups() (portability fix)
8663 - remove use of setenv() (portability fix)
8665 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8667 *) Add access control via environment variables. [Ben Laurie]
8669 *) Add rflush() function. [Alexei Kosut]
8671 *) remove duplicate pcalloc() call in new_connection().
8673 *) Fix incorrect comparison which could allow number of children =
8674 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8675 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8677 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8678 AIX PS/2, CONVEXOS. [Jim Jagielski]
8680 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8681 It's more portable. [Martin Kraemer]
8683 *) Replace references to make in Makefile.tmpl with $(MAKE).
8686 *) Add ProxyBlock directive w/IP address caching. Add IP address
8687 caching to NoCache directive as well. ProxyBlock works with all
8688 handlers; NoCache now also works with FTP for anonymous logins.
8689 Still more code cleanup. [Chuck Murcko]
8691 *) Add "header parse" API hook [Ben Laurie]
8693 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8695 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8697 *) Correctly allow access and auth directives in <Files> sections in
8698 server config files. [Alexei Kosut]
8700 *) Fix bug with ServerPath that could cause certain files to be not
8701 found by the server. [Alexei Kosut]
8703 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8704 double-quote from text and so that it properly checks for unsupported
8705 status codes using the new index_of_response interface. [Roy Fielding]
8707 *) Multiple fixes to the lingering_close code in order to avoid being
8708 interrupted by a stray timeout, to avoid lingering on a connection
8709 that has already been aborted or never really existed, to ensure that
8710 we stop lingering as soon as any error condition is received, and to
8711 prevent being stuck indefinitely if the read blocks. Also improves
8712 reporting of error conditions. [Marc Slemko and Roy Fielding]
8714 *) Fixed initialization of parameter structure for sigaction.
8715 [mgyger@itr.ch, Adrian Filipi-Martin]
8717 *) Fixed reinitializing the parameters before each call to accept and
8718 select, and removed potential for infinite loop in accept.
8719 [Roy Fielding, after useful PR from adrian@virginia.edu]
8721 *) Fixed condition where, if a child fails to fork, the scoreboard would
8722 continue to say SERVER_STARTING forever. Eventually, the main process
8723 would refuse to start new children because count_idle_servers() will
8724 count those SERVER_STARTING entries and will always report that there
8725 are enough idle servers. [Phillip Vandry]
8727 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8728 Avoided calling bflush() when the client is pipelining requests.
8729 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8731 *) Added description of "." mode in server-status [Jim Jagielski]
8733 Changes with Apache 1.2b4
8735 *) Fix possible race condition in accept_mutex_init() that
8736 could leave a small security hole open allowing files to be
8737 overwritten in cases where the server UID has write permissions.
8740 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8742 *) Fix portablity problem in util_script where ARG_MAX may not be
8743 defined for some systems.
8745 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8748 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8749 style magic #! token for better script portability. [Garey Smiley]
8751 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8752 execution for ~userdir CGI. [Jason Dour]
8754 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8756 *) Fix month off by one in suexec wrapper logging.
8758 Changes with Apache 1.2b3:
8760 *) Fix error in mod_cgi which could cause resources not to be properly
8761 freed, or worse. [Dean Gaudet]
8763 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8765 *) Add set_flag_slot() at the request of Dirk and others.
8768 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8770 *) Add changes to improve the error message given for invalid
8771 ServerName parameters. [Dirk vanGulik]
8773 *) Add "Authoritative" directive for Auth modules that don't
8774 currently have it. This gives admin control to assign authoritative
8775 control to an authentication scheme and allow "fall through" for
8776 those authentication modules that aren't "Authoritative" thereby
8777 allowing multiple authentication mechanisms to be chained.
8780 *) Remove requirement for ResourceConfig/AccessConfig if not using
8781 the three config file layout. [Randy Terbush]
8783 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8785 *) Changes to suexec wrapper to fix the following problems:
8786 1. symlinked homedirs will kill ~userdirs.
8787 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8788 3. CGI command lines paramters problems
8789 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8790 [Randy Terbush, Jason Dour]
8792 *) Change create_argv() to accept variable arguments. This fixes
8793 a problem where arguments were not getting passed to the CGI via
8794 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8796 *) Collapse multiple slashes in path URLs to properly apply
8797 handlers defined by <Location>. [Alexei Kosut]
8799 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8801 *) Improve the accuracy of request duration timings by setting
8802 r->request_time in read_request_line() instead of read_request().
8805 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8806 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8808 *) Add the ability to pass different Makefile.tmpl files to Configure
8809 using the -make flag. [Rob Hartill]
8811 *) Fix coredump triggered when sending a SIGHUP to the server caused
8812 by an assertion failure, in turn caused by an uninitialised field in a
8816 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8817 PATH_INFO from previous versions of Apache (in certain situations,
8818 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8819 [later removed in 1.2b11]
8821 *) Add rwrite() function to API to allow for sending strings of
8822 arbitrary length. [Doug MacEachern]
8824 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8826 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8827 NeXT. [Jim Jagielski]
8829 *) Removed recent modification to promote the status code on internal
8830 redirects, since the correct fix was to change the default log format
8831 in mod_log_config so that it outputs the original status. [Rob Hartill]
8833 Changes with Apache 1.2b2:
8835 *) Update set_signals() to use sigaction() for setting handlers.
8836 This appears to fix a re-entrant problem in the seg_fault()
8837 bus_error() handlers. [Randy Terbush]
8839 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8841 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8843 *) proxy_http.c bugfixes: [Chuck Murcko]
8844 1) fixes possible NULL pointer reference w/NoCache
8845 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8846 host would cache nothing if it was in the local domain,
8847 and the local domain was in the NoCache list)
8848 3) Adds Host: header when not available
8849 4) Some code cleanup and clarification
8851 *) mod_include.c bugfixes:
8852 1) Fixed an ommission that caused include variables to not
8853 be parsed in config errmsg directives [Howard Fear]
8854 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8855 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8856 4) Allow backslash-escaping to all quoted text
8857 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8858 5) Pass variable to command line if not set in XSSI's env
8861 *) Fix infinite loop when processing Content-language lines in
8862 type-map files. [Alexei Kosut]
8864 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8866 *) Fixed problem in set_[user|group] that prevented CGI execution
8867 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8869 *) Added PORTING information file. [Jim Jagielski]
8871 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8873 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8875 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8876 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8878 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8879 which caused problems of systems where socket s_addr is >32bits.
8881 *) Added comment to explain (r->chunked = 1) side-effect in
8882 http_protocol.c [Roy Fielding]
8884 *) Replaced use of index() in mod_expires.c with more appropriate
8885 and portable isdigit() test. [Ben Laurie]
8887 *) Updated Configure for ...
8888 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8889 *-dg-dgux* (bad pattern match)
8890 QNX (DEF_WANTHSREGEX=yes)
8891 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8894 and added some user diagnostic info. [Ben Laurie]
8896 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8897 for better portability. [Jim Jagielski]
8899 *) Updated helpers/GuessOS for ...
8900 SCO 5 (recognize minor releases)
8901 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8902 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8903 IRIX64 (-sgi-irix64)
8904 ULTRIX (-unknown-ultrix)
8905 SINIX (-whatever-sysv4)
8906 NCR Unix (-ncr-sysv4)
8907 and fixed something in helpers/PrintPath [Ben Laurie]
8909 Changes with Apache 1.2b1
8911 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8913 Changes with Apache 1.1.1
8915 *) Fixed bug where Cookie module would make two entries in the
8916 logfile for each access [Mark Cox]
8918 *) Fixed bug where Redirect in .htaccess files would cause memory
8919 leak. [Nathan Neulinger]
8921 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8923 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8925 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8927 Changes with Apache 1.1.0
8929 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8931 *) Bring QNX support up to date. [Ben Laurie]
8933 *) Make virtual hosts default to main server keepalive parameters.
8934 [Alexei Kosut, Ben Laurie]
8936 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8938 *) Fix missing address family for connect, also remove unreachable statement
8939 in mod_proxy. [Ben Laurie]
8941 *) mod_env now turned on by default in Configuration.tmpl.
8943 *) Bugs which were fixed:
8944 a) yet more mod_proxy bugs [Ben Laurie]
8945 b) CGI works again with inetd [Alexei Kosut]
8946 c) Leading colons were stripped from passwords [osm@interguide.com]
8947 d) Another fix to multi-method Limit problem [jk@tools.de]
8949 Changes with Apache 1.1b4
8951 *) r->bytes_sent variable restored. [Robert Thau]
8953 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8955 *) More possibly unsecure programs removed from the support directory.
8957 *) More mod_auth_msql authentication improvements.
8959 *) VirtualHosts based on Host: headers no longer conflict with the
8962 *) OS/2 compatibility enhancements. [Gary Smiley]
8964 *) POST now allowed to directory index CGI scripts.
8966 *) Actions now work with files of the default type.
8968 *) Bugs which were fixed:
8969 a) more mod_proxy bugs
8970 b) early termination of inetd requests
8971 c) compile warnings on several systems
8972 d) problems when scripts stop reading output early
8974 Changes with Apache 1.1b3
8976 *) Much of cgi-bin and all of cgi-src has been removed, due to
8977 various security holes found and that we could no longer support
8980 *) The "Set-Cookie" header is now special-cased to not merge multiple
8981 instances, since certain popular browsers can not handle multiple
8982 Set-Cookie instructions in a single header. [Paul Sutton]
8984 *) rprintf() added to buffer code, occurrences of sprintf removed.
8987 *) CONNECT method for proxy module, which means tunneling SSL should work.
8988 (No crypto needed) Also a NoCache config directive.
8990 *) Several API additions: pstrndup(), table_unset() and get_token()
8991 functions now available to modules.
8993 *) mod_imap fixups, in particular Location: headers are now complete
8996 *) New "info" module which reports on installed module set through a
8997 special URL, a la mod_status.
8999 *) "ServerPath" directive added - allows for graceful transition
9000 for Host:-header-based virtual hosts.
9002 *) Anonymous authentication module improvements.
9004 *) MSQL authentication module improvements.
9006 *) Status module design improved - output now table-based. [Ben Laurie]
9008 *) htdigest utility included for use with digest authentication
9011 *) mod_negotiation: Accept values with wildcards to be treated with
9012 less priority than those without wildcards at the same quality
9013 value. [Alexei Kosut]
9015 *) Bugs which were fixed:
9016 a) numerous mod_proxy bugs
9017 b) CGI early-termination bug [Ben Laurie]
9018 c) Keepalives not working with virtual hosts
9019 d) RefererIgnore problems
9020 e) closing fd's twice in mod_include (causing core dumps on
9021 Linux and elsewhere).
9023 Changes with Apache 1.1b2
9026 a) core dumps in mod_digest
9027 b) truncated hostnames/ip address in the logs
9028 c) relative URL's in mod_imap map files
9030 Changes with Apache 1.1b1
9032 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9034 Changes with Apache 1.0.3
9036 *) Internal redirects which occur in mod_dir.c now preserve the
9037 query portion of a request (the bit after the question mark).
9040 *) Escape active characters '<', '>' and '&' in html output in
9041 directory listings, error messages and redirection links.
9044 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9046 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9049 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9051 *) Reset timeout timer after each successful fwrite() to the network.
9052 This patch adds a reset_timeout() procedure that is called by
9053 send_fd() to reset the timeout ever time data is written to the net.
9056 *) timeout() signal handler now checks for SIGPIPE and reports
9057 lost connections in a more user friendly way. [Rob Hartill]
9059 *) Location of the "scoreboard" file which used to live in /tmp is
9060 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9061 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9063 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9065 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9066 which caused a SEGV with cookies enabled
9068 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9071 *) Log the UNIX textual error returned by some system calls, in
9072 particular errors from accept() [David Robinson]
9074 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9076 Changes with Apache 1.0.2
9078 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9079 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9081 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9084 *) past changes to http_config.c to only use the
9085 setrlimit function on systems defining RLIMIT_NOFILE
9086 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9087 for SUNOS and prototypes the needed functions.
9089 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9092 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9094 *) Merge multiple headers from CGI scripts instead of taking last
9095 one. [David Robinson]
9097 *) Add support for SCO 5. [Ben Laurie]
9099 Changes with Apache 1.0.1
9101 *) Silence mod_log_referer and mod_log_agent if not configured
9104 *) Recursive includes can occur if the client supplies PATH_INFO data
9105 and the server provider uses relative links; as file.html
9106 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9108 *) The replacement for initgroups() did not call {set,end}grent(). This
9109 had two implications: if anything else used getgrent(), then
9110 initgroups() would fail, and it was consuming a file descriptor.
9113 *) On heavily loaded servers it was possible for the scoreboard to get
9114 out of sync with reality, as a result of a race condition.
9115 The observed symptoms are far more Apaches running than should
9116 be, and heavy system loads, generally followed by catastrophic
9117 system failure. [Ben Laurie]
9119 *) Fix typo in license. [David Robinson]
9121 Changes with Apache 1.0.0 23 Nov 1995
9123 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9125 Changes with Apache 0.8.16 05 Nov 1995
9127 *) New man page for 'httpd' added to support directory [David Robinson]
9129 *) .htgroup files can have more than one line giving members for a
9130 given group (each must have the group name in front), for NCSA
9131 back-compatibility [Robert Thau]
9133 *) Mutual exclusion around accept() is on by default for SVR4 systems
9134 generally, since they generally can't handle multiple processes in
9135 accept() on the same socket. This should cure flaky behavior on
9136 a lot of those systems. [David Robinson]
9138 *) AddType, AddEncoding, and AddLanguage directives take multiple
9139 extensions on a single command line [David Robinson]
9141 *) UserDir can be disabled for a given virtual host by saying
9142 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9143 that this didn't work. [David Robinson]
9145 *) Compiles on QNX [Ben Laurie]
9147 *) Corrected parsing of ctime time format [David Robinson]
9149 *) httpd does a perror() before exiting if it can't log its pid
9150 to the PidFile, to make diagnosing the error a bit easier.
9153 *) <!--#include file="..."--> can no longer include files in the
9154 parent directory, for NCSA back-compatibility. [David Robinson]
9156 *) '~' is *not* escaped in URIs generated for directory listings
9159 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9161 *) Fixed bug involving handling URIs with escaped %-characters
9162 in redirects [David Robinson]
9164 Changes with Apache 0.8.15 14 Oct 1995
9166 *) Switched to new, simpler license
9168 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9170 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9172 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9174 *) Correctly handles internal redirects to files with names containing '%'
9177 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9179 *) Use geteuid() rather than getuid() to see if we have root privilege,
9180 so that server correctly resets privilege if run setuid root. [Andrew
9183 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9186 *) Fix relative URLs in imagemap files [Randy Terbush]
9188 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9191 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9192 entries all name the same one. [David Robinson]
9194 *) Fix directory listings with filenames containing unusual characters
9197 *) Better URI-escaping for generated URIs in directories with filenames
9198 containing unusual characters [Ben Laurie]
9200 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9202 *) Unblock alarms on error return from spawn_child() [David Robinson]
9204 *) Sample Config files have extra note for SCO users [Ben Laurie]
9206 *) Configuration has note for HP-UX users [Rob Hartill]
9208 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9210 *) Nuked bogus #define in httpd.h [David Robinson]
9212 *) Better test for whether a system has setrlimit() [David Robinson]
9214 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9216 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9219 Changes with Apache 0.8.14 19 Sep 1995
9221 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9223 *) AddDescription works (better) [Ben Laurie]
9225 *) Leaves an intelligible error diagnostic when it can't set group
9226 privileges on standalone startup [Andrew Wilson]
9228 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9229 that machine, which claims to be BSD but does not support RLIMIT.
9232 *) gcc -Wall no longer complains about an unused variable when util.c
9233 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9235 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9237 Changes with Apache 0.8.13 07 Sep 1995
9239 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9241 *) Have built-in imagemap code recognize & honor Point directive [James
9244 *) Generate cleaner directory listings in directories with a mix of
9245 long and short filenames [Rob Hartill]
9247 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9249 *) Properly default ServerName for virtual servers [Robert Thau]
9251 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9252 Paul Richards and a cast of thousands...]
9254 *) On self-identified BSD systems (we don't try to guess any more),
9255 allocate a few extra file descriptors per virtual host with setrlimit,
9256 if we can, to avoid running out. [Randy Terbush]
9258 *) Write 22-character lock file name into buffer with enough space
9259 on startup [Konstantin Olchanski]
9261 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9264 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9266 *) Suppress -Wall warning by initializing variable in negotiation code
9267 [Tobias Weingartner]
9269 Changes with Apache 0.8.12 31 Aug 1995
9271 *) Doesn't pause three seconds after including a CGI script which is
9272 too slow to die off (this is done by not even trying to kill off
9273 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9274 after the entire document has been processed). [Robert Thau]
9276 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9278 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9280 *) Allows .htaccess files to override <Directory> sections naming the
9281 same directory [David Robinson]
9283 *) Removed an efficiency hack in sub_req_lookup_uri which was
9284 causing certain extremely marginal cases (e.g., ScriptAlias of a
9285 *particular* index.html file) to fail. [David Robinson]
9287 *) Doesn't log an error when the requested URI requires
9288 authentication, but no auth header line was supplied by the
9289 client; this is a normal condition (the client doesn't no auth is
9290 needed here yet). [Robert Thau]
9292 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9294 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9296 *) RFC931 code no longer passes out name of prior clients on current
9297 requests if the current request came from a server that doesn't
9298 do RFC931. [David Robinson]
9300 *) Configuration script accepts "Module" lines with trailing whitespace.
9303 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9305 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9307 Changes with Apache 0.8.11 24 Aug 1995
9309 *) Wildcard <Directory> specifications work. [Robert Thau]
9311 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9313 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9314 the file being requested itself, in addition to the directories leading
9315 up to it. [Robert Thau]
9317 *) Logs access failures due to symlink checks or invalid client address
9318 in the error log [Roy Fielding, Robert Thau]
9320 *) Symlink checks deal correctly with systems where lstat of
9321 "/path/to/some/link/" follows the link. [Thau, Fielding]
9323 *) Doesn't reset DirectoryIndex to 'index.html' when
9324 other directory options are set in a .htaccess file. [Robert Thau]
9326 *) Clarified init code and nuked bogus warning in mod_access.c
9329 *) Corrected several directives in sample srm.conf
9330 --- includes corrections to directory indexing icon-related directives
9331 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9332 icons for encodings right, and turning on AddEncoding by default).
9335 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9338 *) INSTALL & README mention "contributed modules" directory [Brian
9341 *) Fixed English in the license language... "for for" --> "for".
9344 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9345 mod_alias.c, merging it almost completely with handling of Alias, and
9346 adding a 'notes' field to the request_rec which allows the CGI module
9347 to discover whether the Alias module has put this request through
9348 ScriptAlias (which it needs to know for back-compatibility, as the old
9349 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9352 Changes with Apache 0.8.10 18 Aug 1995
9354 *) AllowOverride applies to the named directory, and not just
9355 subdirectories. [David Robinson]
9357 *) Do locking for accept() exclusion (on systems that need it)
9358 using a special file created for the purpose in /usr/tmp, and
9359 not the error log; using the error log causes real problems
9360 if it's NFS-mounted; this is known to be the cause of a whole
9361 lot of "server hang" problems with Solaris. [David Robinson;
9362 thanks to Merten Schumann for help diagnosing the problem].
9364 Changes with Apache 0.8.9 12 Aug 1995
9366 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9368 *) Nested includes see environment variables of the including document,
9369 for NCSA bug-compatibility (some sites have standard footer includes
9370 which try to print out the last-modified date). [Eric Hagberg/Robert
9373 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9374 URI as a CGI script, even if it would have been treated as something
9375 else if requested directly, for NCSA back-compatibility. (Note that
9376 this means that people who know the name of the script can see the
9377 code just by asking for it). [Robert Thau]
9379 *) New version of dbmmanage script included in support directory as
9382 *) Check if scoreboard file couldn't be opened, and say so, rather
9383 then going insane [David Robinson]
9385 *) POST to CGI works on A/UX [Jim Jagielski]
9387 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9389 *) NCSA server push works properly --- the Arena bug compatibility
9390 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9391 if you still want the workaround). [Rob Hartill]
9393 *) If client didn't submit any Accept-encodings, ignore encodings in
9394 content negotiation. (NB this will all have to be reworked anyway
9395 for the new HTTP draft). [Florent Guillaume]
9397 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9399 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9401 *) Give Redirect priority over Alias, for NCSA bug compatibility
9404 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9405 paralleling earlier bug fix for CGI [David Robinson]
9407 *) If DBM auth is improperly configured, report a server error and don't
9410 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9411 it seems to work well enough without it (even in a 10 hits/sec
9412 workout), and the overhead for the locking under A/UX is
9413 alarmingly high (though it is very low on other systems).
9414 [Eric Hagberg, Jim Jagielski]
9416 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9418 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9419 Behlendorf/Eric Hagberg]
9421 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9423 *) Compiles clean on NEXT [Rob Hartill]
9425 *) Compiles clean on SGI [Robert Thau]
9427 Changes with Apache 0.8.8 08 Aug 1995
9429 *) SunOS library prototypes now never included unless explicitly
9430 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9431 people using GNU libc on SunOS are screwed by prototypes for the
9434 (Those who wish to compile clean with gcc -Wall on a standard
9435 SunOS setup need the prototypes, and may obtain them using
9436 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9437 with nonstandard libraries are presumably competent to make their
9440 *) Strips trailing '/' characters off both args to the Alias command,
9441 to make 'Alias /foo/ /bar/' work.
9443 Changes with Apache 0.8.7 03 Aug 1995
9445 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9446 [reported by David Robinson]
9448 *) Compiles clean on OSF/1 [David Robinson]
9450 *) Added some of the more recent significant changes (AddLanguage stuff,
9451 experimental LogFormat support) to CHANGES file in distribution root
9454 Changes with Apache 0.8.6 02 Aug 1995
9456 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9457 (If you actually wanted a conditional GET which bypassed the cache, you
9458 couldn't get it). [Reported by Roy Fielding]
9460 *) Properly terminate headers on '304 Not Modified' replies to conditional
9461 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9462 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9464 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9466 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9467 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9468 and older versions don't set the __SUNPRO_C preprocessor variable). On
9469 all other systems, these are never used anyway. [Reported by Mark Cox].
9471 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9473 Changes with Apache 0.8.5 01 Aug 1995
9475 *) Added last-minute configurable log experiment, as optional module
9477 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9478 properly. (One-line fix to http_protocol.c).
9480 *) Work around bogus behavior when reloading from Netscape.
9481 It's Netscape's bug --- for some reason they expect a request with
9482 If-modified-since: to not function as a conditional GET if it also
9483 comes with Pragma: no-cache, which is way out of line with the HTTP
9484 spec (according to Roy Fielding, the redactor).
9486 *) Added parameter to set maximum number of server processes.
9488 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9491 *) IdentityCheck bugfix [Chuck Murcko].
9493 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9495 *) More sample config file corrections; add extension to AddType for
9496 *.asis, move AddType generic description to its proper place, and
9497 fix miscellaneous typos. [ Alexei Kosut ]
9499 *) Deleted the *other* reference to the regents from the Berkeley
9500 legal disclaimer (everyplace).
9502 *) Nuked Shambhala name from src/README; had already cleaned it out
9505 Changes with Apache 0.8.4
9507 *) Changes to server-pool management parms --- renamed current
9508 StartServers to MinSpareServers, created separate StartServers
9509 parameter which means what it says, and renamed MaxServers to
9510 MaxSpareServers (though the old name still works, for NCSA 1.4
9511 back-compatibility). The old names were generally regarded as
9512 too confusing. Also altered "docs" in sample config files.
9514 *) More improvements to default config files ---
9515 sample directives (commented out) for XBitHack, BindAddress,
9516 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9517 defaults, AddTypes for send-as-is and imagemap magic types, and
9518 improvements to samples for DirectoryIndex [Alexei Kosut]
9520 *) Yet more improvements to default config files --- changes to
9521 Alexei's sample AddLanguage directives, and sample LanguagePriority
9522 [ Florent Guillaume ]
9524 *) Set config file locations properly if not set in httpd.conf
9527 *) Don't escape URIs in internal redirects multiple times; don't
9528 do that when translating PATH_INFO to PATH_TRANSLATED either.
9531 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9533 Changes with Apache 0.8.3
9535 *) Edited distribution README to *briefly* summarize installation
9536 procedures, and give a pointer to the INSTALL file in the src/
9539 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9540 recent NCSA distributions.
9542 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9543 exist for the same directory, use both and don't segfault. [Reported
9546 *) Proper makefile dependencies [David Robinson]
9548 *) Note (re)starts in error log --- reported by Rob Hartill.
9550 *) Only call no2slash() after get_path_info() has been done, to
9551 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9552 reported by Andrew Wilson, though this one is probably a real bug]
9554 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9555 dump core when Referer is not supplied. [Randy Terbush]
9557 *) Lightly edited sample config files to refer people to our documentation
9558 instead of NCSA's, and to list Rob McCool as *original* author (also
9559 deleted his old, and no doubt non-functional email address). Would be
9560 nice to have examples of new features...
9562 Changes with Apache 0.8.2 19 Jul 1995
9564 *) Added AddLanuage code [Florent Guillaume]
9566 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9568 *) All sorts of problems when MultiViews finds a directory. It would
9569 be nice if mod_dir.c was robust enough to handle that, but for now,
9570 just punt. [reported by Brian Behlendorf]
9572 *) Wait for all children on restart, to make sure that the old socket
9573 is gone and we can reopen it. [reported by Randy Terbush]
9575 *) Imagemap module is enabled in default Configuration
9577 *) RefererLog and UserAgentLog modules properly default the logfile
9580 *) Mark Cox's mod_cookies added to the distribution as an optional
9581 module (commented out in the default Configuration, and noted as
9582 an experiment, along with mod_dld). [Mark Cox]
9584 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9586 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9588 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9590 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9593 Changes with Apache 0.8.1
9595 *) New imagemap module [Randy Terbush]
9597 *) Replacement referer log module with NCSA-compatible RefererIgnore
9598 [Matthew Gray again]
9600 *) Don't mung directory listings with very long filenames.
9603 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9605 *) New config script. See INSTALL for info. [Robert Thau]
9607 *) Scoreboard mechanism for regulating the number of extant server
9608 processes. MaxServers and StartServers defaults are the same as
9609 for NCSA, but the meanings are slightly different. (Actually,
9610 I should probably lower the MaxServers default to 10).
9612 Before asking for a new connection, each server process checks
9613 the number of other servers which are also waiting for a
9614 connection. If there are more than MaxServers, it quietly dies
9615 off. Conversely, every second, the root, or caretaker, process
9616 looks to see how many servers are waiting for a new connection;
9617 if there are fewer than StartServers, it starts a new one. This
9618 does not depend on the number of server processes already extant.
9619 The accounting is arranged through a "scoreboard" file, named
9620 /tmp/htstatus.*, on which each process has an independent file
9621 descriptor (they need to seek without interference).
9623 The end effect is that MaxServers is the maximum number of
9624 servers on an *inactive* server machine, but more will be forked
9625 off to handle unusually heavy loads (or unusually slow clients);
9626 these will die off when they are no longer needed --- without
9627 reverting to the overhead of full forking operation. There is a
9628 hard maximum of 150 server processes compiled in, largely to
9629 avoid forking out of control and dragging the machine down.
9630 (This is arguably too high).
9632 In my server endurance tests, this mechanism did not appear to
9633 impose any significant overhead, even after I forced it to put the
9634 scoreboard file on a normal filesystem (which might have more
9635 overhead than tmpfs). [Robert Thau]
9637 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9640 *) Read .htaccess files even in directory with <Directory> section.
9641 (Former incompatibility noted on mailing list, now fixed). [Robert
9644 *) "HEAD /" gives the client a "Bad Request" error message, rather
9645 than trying to send no body *and* no headers. [Cliff Skolnick].
9647 *) Don't produce double error reports for some very obscure cases
9648 mainly involving auth configuration (the "all modules decline to
9649 handle" case which is a sure sign of a server bug in most cases,
9650 but also happens when authentication is badly misconfigured).
9653 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9654 it's *for*, and this sort of thing really shouldn't be cluttering
9655 up the Makefile). [Robert Thau]
9657 *) Incidental code cleanups in http_main.c --- stop dragging
9658 sa_client around; just declare it where used. [Robert Thau]
9660 *) Another acc-related fix. (It doesn't like const char
9661 in some places...). [Mark Cox]
9663 Changes with Shambhala 0.6.1 13 Jul 1995
9665 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9666 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9668 *) Compiles clean with acc on SunOS [Paul Sutton]
9670 *) Reordered modules in modules.c so that Redirect takes priority
9671 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9672 believe it or not, he has an actual site with a ScriptAlias and
9673 a Redirect declared for the *exact same directory*. Even *my*
9674 compatibility fetish wouldn't motivate me to fix this if the fix
9675 required any effort, but it doesn't, so what the hey.
9677 *) Fixed to properly default several server_rec fields for virtual
9678 servers from the corresponding fields in the main server_rec.
9679 [Cliff Skolnick --- 'port' was a particular irritant].
9681 *) No longer kills off nph- child processes before they are
9682 finished sending output. [Matthew Gray]
9684 Changes with Shambhala 0.6.0 10 Jul 1995
9686 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9687 the connection to the client in an "aborted" state, but otherwise
9688 allow whatever handlers are running to clean up. hard_timeout()s
9689 abort the request in progress completely; anything not tied to some
9690 resource pool cleanup will leak. They're still around because I
9691 haven't yet come up with a more elegant way of handling
9692 timeouts when talking to something that isn't the client. The
9693 default_handler and the dir_handler now use soft timeouts, largely
9694 so I can test the feature. [Robert Thau]
9696 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9697 the case of log handlers dying prematurely is probably handled VERY
9698 gracelessly at this point, and if the logger stops reading input,
9699 the server will hang. (It is known to correctly restart the
9700 logging process on server restart; this is (should be!) going through
9701 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9702 script). [Robert Thau]
9704 *) asis files supported (new module). [Robert Thau]
9706 *) IdentityCheck code is compiled in, but has not been tested. (I
9707 don't know anyone who runs identd). [Robert Thau]
9709 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9710 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9712 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9714 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9715 as timeouts are not in scope. [Robert Thau]
9717 *) quoted-string args in config files now handled correctly (doesn't drop
9718 the last character). [Robert Thau; reported by Randy Terbush]
9720 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9721 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9723 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9724 default default type); the former default default behavior when all
9725 type-checkers defaulted had been a core dump. [Paul Sutton]
9727 *) Copy filenames out of the struct dirent when indexing
9728 directories. (On Linux, readdir() returns a pointer to the same
9729 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9731 Changes with Shambhala 0.5.3 [not released]
9733 *) Default response handler notes "file not found" in the error log,
9734 if the file was not found. [Cliff Skolnick].
9736 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9737 code no longer sets up bogus PATH_INFO which fakes out the directory
9738 handler). [Cliff Skolnick]
9740 Changes with Shambhala 0.5.2 06 Jul 1995
9742 *) Changes to http_main.c --- root server no longer plays silly
9743 games with SIGCHLD, and so now detects and replaces dying
9744 children. Child processes just die on SIGTERM, without taking
9745 the whole process group with them. Potential problem --- if any
9746 child process refuses to die, we hang in restart.
9747 MaxRequestsPerChild may still not work, but it certainly works
9748 better than it did before this! [Robert Thau]
9750 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9751 work (or work better, at least); over-long description lines
9752 properly terminated. [Mark Cox]
9754 *) http_request.c now calls unescape_url() more places where it
9755 should [Paul Sutton].
9757 *) More directory handling bugs (reported by Cox)
9758 Parent Directory link is now set correctly. [Robert Thau]
9760 Changes with Shambhala 0.5.1 04 Jul 1995
9762 *) Generalized cleanup interface in alloc.c --- any function can be
9763 registered with alloc.c as a cleanup for a resource pool;
9764 tracking of files and file descriptors has been reimplemented in
9765 terms of this interface, so I can give it some sort of a test.
9768 *) More changes in alloc.c --- new cleanup_for_exec() function,
9769 which tracks down and closes all file descriptors which have been
9770 registered with the alloc.c machinery before the server exec()s a
9771 child process for CGI or <!--#exec-->. CGI children now get
9772 started with exactly three file descriptors open. Hopefully,
9773 this cures the problem Rob H. was having with overly persistent
9774 CGI connections. [Robert Thau]
9776 *) Mutual exclusion around the accept() in child_main() --- this is
9777 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9778 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9779 This uses fcntl(F_SETLK,...) on the error log descriptor because
9780 flock() on that descriptor won't work on systems which have BSD
9781 flock() semantics, including (I think) Linux 1.3 and Solaris.
9783 This does work on SunOS (when the server is idle, only one
9784 process in the pool is waiting on accept()); it *ought* to work
9785 on the other systems. [Robert Thau]
9787 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9789 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9791 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9793 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9794 be unnecessary if I go to the revised timeout-handling scheme).
9797 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9798 string) even if none came in with the request. [Robert Thau]
9800 *) CHANGES file added to distribution ;-).
9802 Changes with Shambhala 0.4.5
9804 *) mod_dld --- early dynamic loading support [rst]
9805 *) Add wildcard content handlers for XBITHACK; default_hander now
9806 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9807 *) XBITHACK supported as a wildcard content-handler, and
9808 configurable at run-time (not just at compile time, as in the
9809 "patchy server" releases) [rst]
9811 Changes with Shambhala 0.4.4 30 Jun 1995
9813 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9814 *) Handle Addtype x/y .z [rst, reported by Cox]
9816 Changes with Shambhala 0.4.3
9818 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9819 synonymous [rst, terbush]
9821 Changes with Shambhala 0.4.1 28 Jun 1995
9823 *) First-cut virtual host implementation; some refit in the config
9824 reading code, and log management, was necessary to support this [rst]
9825 *) Sub-pool machinery, originally added to avoid excessive storage
9826 allocation on listings of large directories (which turned out to
9827 be the problem that the 0.3 storage accounting was added to
9828 find). Subrequests and mod_dir changed to use subpools. [rst]
9829 *) More memory debugging --- free list consistency checks. [rst]
9830 *) Added err_headers to request_rec, with support elsewhere [rst]
9831 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9833 Changes with Shambhala 0.3 19 Jun 1995
9835 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9836 *) Don't compile in mod_ai_backcompat by default
9837 *) Switch name of server from Apache to Shambhala in Makefile
9838 *) Add some accounting routines to track memory usage in the pools,
9841 Changes with Shambhala 0.2
9843 *) Set DOCUMENT_ROOT CGI variable
9844 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9845 *) Add critical section protection to handling of cleanup structures
9847 *) Significant code reorg within the server core to group related
9848 functions together [rst]
9849 *) Correctly handle clients that hang up before sending any request
9851 *) Replace dying child processes. [rst]
9853 Changes with Shambhala 0.1 12 Jun 1995
9855 Major rewrite of the pre-existing "patchy server" codebase, by
9856 Robert Thau (rst). Significant portions of the server code, such
9857 as configuration-file handling and HTTP authentication support,
9858 were ripped out and rewritten from scratch. Code that was not
9859 completely rewritten was significantly altered.
9861 Major changes with this release include:
9863 *) Introduction of the module API; in request handling, the central
9864 machinery just dispatches to various modules, which actually do
9865 most of the work. Configuration handling is similar --- modules
9866 declare their own commands, and the central machinery just
9869 API features from shambhala/0.1 were substantially unchanged in
9870 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9871 release, such as wildcard handlers and subpools, were added in
9872 subsequent Shambhala releases, and were also generally rst's
9875 *) This release included the following modules:
9877 mod_access (access control --- allow and deny directives),
9878 mod_alias (Alias and Redirect commands),
9879 mod_auth (straight HTTP authentication, based on flat-files)
9880 mod_auth_dbm (same, with dbm files)
9881 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9882 mod_common_log (CLF access logs; later renamed mod_log_common)
9883 mod_dir (directory indexing)
9884 mod_include (server-side includes)
9885 mod_mime (AddType directives)
9886 mod_negotiation (content negotiation)
9887 mod_userdir (support for users' public_html directories)
9889 It also included a mod_ai_backcompat, which was a private hack
9890 for back-compatibility with rst's own AI-lab servers.
9892 All of these modules were substantially complete, and functional
9893 or nearly so (a few, which implemented features not in use at
9894 Thau's site, required patches of a few lines).
9896 *) sub-request machinery, to allow modules to determine how other
9897 modules would assign MIME types to a given file, or optionally
9898 serve its content (this is heavily used by mod_dir, mod_include
9899 and mod_negotiation).
9901 *) Resource pool system for keeping track of memory allocated and
9902 files opened in service of a particular request. Much of the
9903 code in the modules (when they weren't rewrites) was adjusted to
9904 replace a pervasive convention of using fixed-size buffers on
9905 the stack with an equally pervasive convention of using memory
9906 allocated with palloc().
9908 *) Reorganization of data structures associated with a given
9909 request to eliminate use of global variables and the troublesome
9910 unmunge_name function (used in NCSA and early Apache releases to
9911 attempt to determine the URI which mapped to a given filename
9912 --- a difficult proposition, given that it is easy to produce
9913 setups in which multiple URIs map to the same file).
9915 *) Source files renamed and rearranged
9917 *) Very simple pre-forking behavior --- parent process forked off a
9918 fixed number of children, and then just waited for SIGHUP.
9920 *) Other more minor changes too numerous to list.
9922 This release included modified versions of a lot of code from the
9923 Apache 0.6.4 public release, plus an early pre-forking patch
9924 codeveloped by Robert Thau and Rob Hartill.
9926 Changes with Apache 0.7.3 20 Jun 1995
9928 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9929 were incorporated by Rob Hartill on the main branch while Robert Thau
9930 worked on the Shambhala rewrite above. Most were merged into the
9931 Shambala architecture after Apache 0.8.0.
9933 Changes with Apache 0.6.4 13 May 1995
9935 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9938 Changes with Apache 0.5.1 10 Apr 1995
