1 Changes with Apache 2.0.25-dev
3 Changes with Apache 2.0.24
5 *) The Unix MPMs other than perchild now allow child server
6 processes to use the accept mutex when starting as root and
7 using SysV sems for the accept mutex. Previously, this
8 combination would lead to fatal errors in the child server
9 processes. perchild can't use SysV sems because of security
10 issues. [Jeff Trawick, Greg Ames]
12 *) Added Win32 revision stamp resources to all http binaries
13 (including modules/ and support/ tools.) PR7322 [William Rowe]
15 *) Fix ap_rvprintf to support more than 4K of data at one time.
16 [Cody Sherr <csherr@covalent.net>]
18 *) We have always used the obsolete/deprecated Netscape syntax
19 for our tracking cookies; now the CookieStyle directive
20 allows the Webmaster to choose the Netscape, RFC2109, or
21 RFC2965 format. The new CookieDomain directive allows the
22 setting of the cookie's Domain= attribute, too. PR #s 5006,
23 5023, 5920, 6140 [Ken Coar]
25 *) Tweak server/Makefile so that the rules for generating exports.c
26 are compatible with make utilities which don't expand wildcards
27 in a dependency list (e.g., OS/390 make, certain levels of GNU
30 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
32 *) Begin to sanitize the MPM configuration directives. Now, all
33 MPMs use the same functions for all common MPM directives. This
34 should make it easier to catch all bugs in these directives once.
35 [Cody Sherr <csherr@covalent.net>]
37 *) Close a major resource leak. Every time we had issued a
38 graceful restart, we leaked a socket descriptor.
41 *) Fix a problem with the new method code. We need to cast
42 the 1 to an apr_int64_t or it will be treated as a 32-bit
43 integer, and it will wrap after being shifted 32 times.
44 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
46 *) Fix a bug in mod_expires. Previous to this patch, if you
47 told mod_expires to add 604800 seconds to the last-modified
48 time, it actually added 604800 usec's to the last-modified time,
49 so that when looking at the response it looked like nothing
50 had been done. The root of the problem was that we always compute
51 time in usec's, but we ask users to input sec's. This means we
52 need to convert to usec's before using those values.
55 *) The worker MPM now handles shutdown and restart requests. It
56 definitely isn't perfect, but we do stop the servers correctly.
57 The biggest problem right now is that SIGHUP causes the server to
58 just die. [Ryan Bloom]
60 Changes with Apache 2.0.23
62 *) Use the prefork MPM by default on Unix. [various]
64 *) Added a systray icon monitor application for Win32.
65 [Mladen Turk <mturk@mappingsoft.com>]
67 *) mod_rewrite: Fix the line ending on some non-Unix systems for
68 messages written to the rewrite log.
69 [Richard Labennett <rlabenn@us.ibm.com>]
71 *) All mod_autoindex query parsing is now quietly quashed with the
72 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
73 still drops the column sort <a href>'s for the column headers, but
74 IgnoreClient is required to ignore these Query options entirely.
77 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
78 to allow the client to select plain, FancyIndexing or HTMLTable
79 formatting, V=[0|1] to inhibit or enable version sorting, and
80 P=pattern to return only specific files. The old Query Arguments
81 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
82 as before), and O=A|D for ordering ascending or descending.
85 *) Fixed an error in mod_include's directive parsing routines which
86 caused #if, #elif, and #else expressions containing backslashes
87 to be improperly evaluated. [Cliff Woolley]
89 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
90 drop the icon column, SuppressRules to drop the <hr> elements,
91 and HTMLTable to create rudimentary HTML table listings (implies
92 FancyIndexing). [William Rowe]
94 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
95 from Apache 1.3.15. This is needed for two reasons, first, given
96 multiple machines within a server farm, ETags and Last-Modified
97 stamps won't correspond from machine to machine, and second, many
98 Unixes don't capture changes to the date or time stamp of existing
99 files, since these don't modify the dirent itself. [William Rowe]
101 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
102 and DirectoryWidth options from Apache 1.3.10.
103 [William Rowe, Ken Coar]
105 *) Eliminated FancyIndexing directive, deprecated early in Apache
106 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
108 *) mod_autoindex now excludes any file names that would result in
109 an error, other than a success or redirect. Also optimized
110 the parent directory, always included except in the URI '/'.
113 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
114 negotiated index pages, and prevent the server from defaulting
115 to an autoindex of the directory. mod_negotiation will now die
116 with a 500 Internal Error if it could match some filenames
117 (e.g. for mod_dir) but none can be served. mod_negotation now
118 refuses to serve any file with an extention that mod_mime doesn't
119 recognize, and wasn't part of the request. [William Rowe]
121 *) Eliminate mod_cgi's handling of .exe files without the .exe file
122 extension. This is already handled by multiviews, if the admin
123 wishes to AddHandler .exe or define a content type handler and
124 associate .exe files with that content type. Multiviews must be
125 enabled to allow these to be served. [William Rowe]
127 *) Speed up the server's response to a spike in incoming workload
128 or restarts by assigning empty scoreboard slots to new processes
129 when they are available. [Greg Ames]
131 *) Add a handler to mod_includes.c. This handler is designed to
132 implement the XbitHack directive. This can't be done with a
133 fixup, because we need to check the content-type, which is
134 only available in the handler phase. [Ryan Bloom]
136 *) Make the includes filter check return codes from filters lower in
137 the filter chain. If a lower level filter returns an error, then
138 the request needs to stop immediately. This allows mod_include to
139 stop parsing data once a lower filter recognizes an error.
142 *) Add the ability to extend the methods that Apache understands
143 and have those methods <limit>able in the httpd.conf. It uses
144 the same bit mask/shifted offset as the original HTTP methods
145 such as M_GET or M_POST, but expands the total bits from an int to
146 an ap_int64_t to handle more bits for new request methods than
147 an int provides. [Cody Sherr <csherr@covalent.net>]
149 *) Fix broken mod_mime behavior in merging its arguments. Possible
150 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
152 *) Solve many mod_ssl porting issues (too many to detail) with
153 help from the whole team, but most notably [Ralf S. Engelschall,
154 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
155 Doug MacEachern, William Rowe, Cliff Woolley]
157 *) More stall fixes for the threaded & worker mpm's.
158 Make mod_status output more accurate. Don't
159 count workers in processes which aren't actively
160 serving requests. [Greg Ames]
162 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
164 *) Add a single listener/multiple worker MPM. This MPM is
165 definately not fully correct, but it allows us to solve many
166 of the problems that exist in the threaded MPM. This is a
167 modified version of the threaded MPM. [Ryan Bloom]
169 *) Improve content generation throughout Apache, providing closer
170 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
171 Transitional specifications. [William Rowe]
173 Changes with Apache 2.0.22
175 *) Fix a problem where the threaded MPM stalls after restarts or
176 segfaults. Also prevent multiple active processes from using
177 the same scoreboard slot. [Greg Ames]
179 *) Apache/Win32 now fills in the service description with Apache's
180 server version string, including loaded and advertised modules.
183 *) Improved support for the Win32 build, to recover gracefully from
184 missing apr or apr-util directories or the awk interpreter,
185 create the proper cgi-bin examples, including a test-cgi.bat, and
186 fix the perl shebang line for printenv.pl, when installing from
187 the build environment. [William Rowe]
189 *) Fix a segfault in threaded.c caused by passing uninitialized
190 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
192 *) Use new APR number conversion functions to reduce CPU consumption
193 when setting the content length, and in mod_log_config.
196 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
197 where HEAD response headers were being repeated twice for
198 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
199 problem in the http_header filter was exposed by the recent rewrite
200 of the content_length filter. [Taketo Kabe, Bill Stoddard]
202 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
203 restarts. A garbage pointer to a vhost's server_rec from the
204 previous generation was being left around under certain
205 conditions. [Greg Ames]
207 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
208 used to appear as '(none', without the closing paren.
209 [Günter Knauf <eflash@gmx.net>]
211 *) Improve the exports generating awk script. In the past, we had
212 work around problems in the awk script by avoiding some #if and
213 #ifdefs. This has bitten us many times in generating the exports.c
214 file. This improvement allows corrects the header file parsing.
215 [Sander Striker <striker@apache.org>]
217 Changes with Apache 2.0.21
219 *) Resolve the Win32 htpasswd bug, where a file that existed would be
220 overwritten, regardless of the -c flag.
221 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
223 *) Introduce connection sub-pools into ab. Truncating the lifetime
224 of these allocations means that ab no longer perpetually grows
225 its working set, running out of memory on large request attempts.
228 *) Make scoreboard creation a hook. This allows management
229 modules to have access to the scoreboard at the time that it is
230 created, and at every restart request.
231 [Cody Sherr <csherr@covalent.net>]
233 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
234 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
235 daemon index actually used in the scoreboard. I also
236 updated the pertinent calls. [Paul J. Reder]
238 *) Win32: Prevent listening sockets from being inherited by
239 the Apache child process, CGI scripts, rotatelog process
240 etc. If the Apache child process segfaults, any processes
241 that the child started are not reaped. Prior to this fix,
242 these processes inherited the listening sockets which sometimes
243 prevented the restarted Apache child process from accepting
244 connections (ie, the server would hang).
247 *) Provide vhost and request strings when ExtendedStatus is on.
250 *) Fix some issues with the pod and prefork: check the pod *after*
251 processing a connection so that a server processing a time-
252 consuming request bails out as soon as practical; when the
253 parent process wakes up a server process via connect(), use an
254 APR timeout on the connect() so that we don't hang for a long
255 time if there aren't server processes around to do accept().
256 [Jeff Trawick, Greg Ames]
258 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
259 spends a lot of time in apr_table_get calls. Using the default
260 httpd.conf, the tables for languages and charsets are somewhat
261 large, so the time spent scanning them on each request is
262 significant. Replacing the tables with hash tables provides
263 a nice speedup. [Brian Pane <bpane@pacbell.net>]
265 *) Add two functions to allow modules to access random parts of the
266 scoreboard. This allows modules compiled for one MPM to access the
267 scoreboard, even if it the server was compiled for another MPM.
268 [Harrie Hazewinkel <harrie@covalent.net>]
270 Changes with Apache 2.0.20
272 *) Fix problem in content-length filter where the filter would
273 buffer all the output from a CGI before sending any bytes
274 down the filter stack to the network. This problem would cause
275 significant memory consumption if the CGIs generated
276 lots of bytes. [Bill Stoddard]
278 *) Get non-blocking CGI pipe reads working with the bucket brigades.
281 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
284 *) Fix a bug in the threaded MPM that would cause it to kill off all
285 workers immediately after starting if the number of workers started
286 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
288 Changes with Apache 2.0.19
290 *) Fix problem with threaded MPM. The problem was that if each child
291 process was busy serving a single long-lived request and the server
292 was sent a graceful restart signal, the server would stop serving
293 requests. This would happen because each child process would wait to
294 die until the last thread was done, and the parent wouldn't spawn any
295 new children until a process died. Now, the parent looks at the fact
296 that the children are dying gracefully, and starts new children.
297 Those new children only start enough threads to compliment the number
298 of threads in the other child process that shares the same spot in
299 the scoreboard. In this way, we make sure to never go over
300 MaxClients. [Ryan Bloom]
302 *) modified mod_negotiation and mod_autoindex to speed up by almost a
303 factor of two on apr_dir_read()-enhanced platforms, such as Win32
304 and OS2, by calling ap_sub_request_lookup_dirent() with the results
305 already provided by apr_dir_read(). [William Rowe]
307 *) mod_file_cache is now more robust to filtering and serves requests
308 slightly more efficiently. [Cliff Woolley]
310 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
311 Module was calling ap_rwrite() followed by ap_rflush() but the
312 served content was not being displayed in the browser. Inspection
313 of the output stream revealed that the first data chunk was
314 missing the trailing CRLF required by the RFC. [Bill Stoddard]
316 *) apxs no longer generates ap_send_http_header() in the example handler
318 *) Fix an ab problem which could cause a divide-by-zero exception
319 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
320 [Ian Holsman <ianh@cnet.com>]
322 *) Solve case-insensitive platforms' confusion about negotiated
323 filenames, allowing files of differnt case to match in choosing
324 the document to serve. [William Rowe]
326 *) Fix brokenness when ThreadsPerChild is higher than the built-in
327 limit. We left ap_threads_per_child at the higher value which
328 led to segfaults when doing certain scoreboard operations.
331 *) Fix seg faults and/or missing output from mod_include. The
332 default_handler was using the subrequest pool for files and
333 MMAPs, even though the associated APR structures typically
334 live longer than the subrequest. [Greg Ames]
336 *) Extend mod_setenvif to support specifying regular expressions
337 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
338 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
339 will cause HAVE_TS to be set if any of the request headers begins
340 with "TS" and has a value that begins with any character in the
341 set [a-z]. [Bill Stoddard]
343 *) httpd children now re-bind themselves to a random CPU on
344 multiprocessor systems on AIX via bindprocessor() in 2.0.
345 [Victor J. Orlikowski]
347 *) Fix htdigest. It would go into a loop in getline when adding
348 a second user. [Bill Stoddard]
350 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
352 *) Automatically generate httpd.exp for AIX.
353 DSOs now work again on AIX in 2.0
354 [Victor J. Orlikowski]
356 *) Add a new request hook, error_log. This phase allows modules
357 to act on the error log string _after_ it has been written
358 to the error log. The goal for this hook is to allow monitoring
359 modules to send the error string to the monitoring agent.
362 *) Modify mod_echo to make it use filters for input and output.
363 [Ryan Morgan <rmorgan@covalent.net>]
365 *) Extend mod_headers to support conditional driven Header
366 add, append and set. Use SetEnvIf to set an envar and conditionally
367 add/append/set headers based on this envar thusly:
369 SetEnvIf TSMyHeader value HAVE_TSMyHeader
370 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
372 If the request contains header "TSMyHeader: value" then header
373 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
376 *) Extend mod_headers to support using format specifiers on Header
377 add, append and set header values. Two format specifiers are supported:
379 %t - reports, in UTC microseconds since the epoch, when the
380 request was received.
382 %D - reports the time, in microseconds, between when the request was
383 received and the response sent.
386 Header add MyHeader "This request served in %D microseconds. %t"
388 results in a header being added to the response that looks like this:
390 MyHeader: This request served in D=5438 microseconds. t=991424704447256
394 *) Fix reset_filter(). We need to be careful how we remove filters.
395 If we set r->output_filters to NULL, we also have to reset the
396 connection's filters. [John Sterling]
398 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
400 *) Add a check to ap_die() to make sure the filter stack is sane and
401 contains the correct basic filters when an error occurs. This fixes
402 a problem where headers are not being sent on error. [John Sterling]
404 *) New Header directive 'echo' option. "Header echo regex" will
405 cause any headers received on the request that match regex to be
406 echoed to (included in) the response headers.
409 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
410 This prevented the inclusion of apr_compat.h. PR #7773
411 [Oleg Broytmann <phd@phd.pp.ru>]
413 *) Moved util_uri to the apr-util library. This required a bunch of
414 apr_name changes for the uri utility functions. [Justin Erenkrantz]
416 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
417 insert_filter phase so that other filters are not bypassed by default.
420 *) Reimplement mod_headers as an output filter. mod_headers can now
421 add custom headers to inbound requests using the RequestHeader directive
422 and to responses using the same old Header directive. [Graham Leggett]
424 Changes with Apache 2.0.18
426 *) Fix command-line processing so that if a bad argument is specified
427 Apache will exit. [Jeff Trawick]
429 *) Change the make targets and rules to be consistent in all of the
430 Apache-owned source trees. [Roy Fielding]
432 *) Fix processing of the TRACE method. Previously we passed bogus
433 parms to form_header_field() and it overlaid some vhost structures,
434 resulting in a segfault in check_hostalias().
435 [Greg Ames, Jeff Trawick]
437 *) Win32: Add support for reliable piped logs. If the logging process
438 goes down, Apache will automatically restart it. This function has
439 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
442 *) Do not start piped log processes during the config file
443 preflight. This change also circumvents a problem on
444 Windows where the rotatelog processes created during preflight
445 was not getting cleaned up properly.
448 *) add "Request Phase Participation" info to mod_info
451 *) Make first phase changes to the scoreboard data structures in
452 preparation for the rewriting of the scoreboard per my posted
453 design notes. [Paul J. Reder]
455 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
456 and apr-util, allow it to be overridden by the configure command-line
457 (default="--silent") and introduce LT_LDFLAGS to replace what we were
458 formerly abusing as LTFLAGS. [Roy Fielding]
460 *) Clean up the reporting of incorrect closing container tags.
461 [Barrie Slaymaker <barries@slaysys.com>]
463 *) Simplify the configure process by moving all libtool stuff to APR
464 and moving hints.m4 inline. [Roy Fielding]
466 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
467 of functions used by mod_proxy for export in the DLL
468 [Ian Holsman <IanH@cnet.com>]
470 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
471 request body from its stdin but no reqest body is being written to
472 the cgi. [Jeff Trawick]
474 *) mod_log_config: %c connection status incorrectly logged
475 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
478 *) Get mod_cern_meta working under Windows
481 *) Create Files, and thus MMAPs, out of the request pool, not the
482 connection pool. This solves a small resource leak that had us
483 not closing files until a connection was closed. In order to do
484 this, at the end of the core_output_filter, we loop through the
485 brigade and convert any data we have into a single HEAP bucket
486 that we know will survive clearing the request_rec.
487 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
490 *) Completely revamp configure so that it preserves the standard make
491 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
492 the configure additions to EXTRA_* variables. Also, allow the user
493 to specify NOTEST_* values for all of the above, which eliminates the
494 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
495 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
496 avoid pointless duplications. Fix the order in which flags are given
497 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
498 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
499 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
500 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
502 *) Get mod_tls to compile/work better on Windows. PR #7612
503 [Bernhard Schrenk <b.schrenk@improx.com>]
505 *) Fix shutdown/restart hangs in the threaded MPM.
506 [Jeff Trawick, Greg Ames, Ryan Bloom]
508 *) Removed the keptalive boolean from conn_rec because it is now only
509 used by a single routine and can be replaced by a local variable.
510 [Greg Stein, Ryan Bloom, Roy Fielding]
512 *) Patch prefork to put enough of the signal processing back in so that
513 signals are all handled properly now. The previous patch fixed the
514 deadlock race condition, but broke the user directed signal handling.
515 This fixes it to work the way it did before my previous prefork patch
516 (primarily, SIGTERM is now working).
518 *) Change how input filters decide how much data is returned to the
519 higher filter. We used to use a field in the conn_rec, with this
520 change, we use an argument to ap_get_brigade to determine how much
521 data is retrieved. [Ryan Bloom]
523 *) Fix seg fault at start-up introduced by Ryan's change to enable
524 modules to specify their own logging tags. mod_log_config
525 registers an optional function, ap_register_log_handler().
526 ap_register_log_handler() was being called by http_core before
527 the directive hash table was created. This patch creates the
528 directive hash table before ap_register_log_handler() is
529 registered as an optional function.
530 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
532 *) Add ap_set_int_slot() function
533 [John K. Sterling <sterling@covalent.net>]
535 *) Under certain circumstances, Apache did not supply the
536 right response headers when requiring authentication.
537 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
538 (This is a port of the change that went into Apache 1.3.19.)
540 *) Allow modules to specify their own logging tags. This basically
541 allows a module to tell mod_log_config that when %x is encountered
542 a specific function should be called. Currently, x can be any single
543 character. It may be more useful to make this a string at some point.
546 Changes with Apache 2.0.17
548 *) If a higher-level filter handles the the byterange aspects of a
549 request, then the byterange filter should not try to redo the
550 work. The most common case of this happening, is a byterange
551 request going through the proxy, and the origin server handles
552 the byterange request. The proxy should ignore it.
553 [Graham Leggett <minfrin@sharp.fm>]
555 *) Changed the threaded mpm to have child_main join to each of the
556 worker threads to make sure the kids are all gone before child_main
557 exits after a signal (cleanup from perform_idle_server_maintenance).
558 This is an extension of Ryans recent commit to make the child_main
561 *) Add more options to the ap_mpm_query function. This also allows MPMs to
562 report if their threads are dynamic or static. Finally, this also
563 implements a new API, ap_show_mpm, which returns the MPM that was
564 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
566 *) Do not install the binaries from the support directory twice.
567 [jun-ichiro hagino <itojun@iijlab.net>]
569 *) The ap_f* functions should flush data to the filter that is passed
570 in, not the the filter after the one passed in.
571 [Ryan Morgan <rmorgan@covalent.net>]
573 *) Make ab work again by changing its native types to apr types and formats.
574 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
576 *) Move the byterange filter and all of the supporting functions back
577 to the HTTP module. The byterange filter turned out to be very
578 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
580 *) Make clean, distclean, and extraclean consistently according to the
581 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
583 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
584 This may have been causing problems stopping processes in the threaded
587 *) Fix content-length in mod_negotiation to a long int representation.
590 *) Remove BindAddress from the default config file.
591 [giles@nemeton.com.au]
593 *) Allow module authors to add a module to their Apache build using
594 --with-module, without re-running buildconf. The syntax is:
595 --with-module=module_type:/path/to/module.c
596 The configure script will copy the module.c file to
597 modules/module_type, and it will be added to the relevant Makefiles.
598 currently, this only works for static modules. [Ryan Bloom]
600 *) Changes required to make prefork clean up idle children properly.
601 There was a window during which a starting worker deadlocks when
602 an idle cleanup arrives before it completes init. Apache then keeps
603 trying to cleanup the same deadlocked worker forever (until higher
604 pids come along, but it still will never reduce below the deadlocked
605 pid). Thus the number of children would not reduce to the correct
606 idle level. [Paul J. Reder]
608 Changes with Apache 2.0.16
610 *) Change the default installation directory to /usr/local/apache2,
611 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
613 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
616 *) Get MaxRequestsPerChild working with the Windows MPM.
619 *) Make generic hooks to work, with mod_generic_hook_import/export
620 experimental modules. [Ben Laurie, Will Rowe]
622 *) Fix segfaults for configuration file syntax errors such as
623 "<Directory>" followed by "</Directory" and
624 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
626 *) Cleanup the --enable-layout option of configure. This makes
627 us use a consistent location for the config.layout file, and it
628 makes configure more portable.
629 [jun-ichiro hagino <itojun@iijlab.net>]
631 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
632 csv/gnuplot format, rudimentary ssl support and various other tweaks
633 to make results more true to what is measured. The upshot of this it
634 turns out that 'ab' has often underreported the true performance of
635 apache. Often by a order of magnitude :-) See talk/paper of Sander
636 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
637 [Dirk-Willem van Gulik]
639 *) Clean up mod_cgid's temporary request pool. Besides fixing a
640 storage leak this ensures that some unnecessary pipes are closed.
643 *) Performance: Add quick_handler hook. This hook is called at the
644 very beginning of the request processing before location_walk,
645 translate_name, etc. This hook is useful for URI keyed content
646 caches like Mike Abbott's Quick Shortcut Cache.
649 *) top_module global variable renamed to ap_top_module [Perl]
651 *) Move ap_set_last_modified to the core. This is a potentially
652 controversial change, because this is kind of HTTP specific. However
653 many protocols should be able to take advantage of this kind of
654 information. I expect that headers will need one more layer of
655 indirection for multi-protocol work, but this is a small step in
656 the right direction. [Ryan Bloom]
658 *) Enable mod_status by default. This matches what Apache 1.3 does.
661 *) Add a ScriptSock directive to the default config file. This is
662 only enabled when mod_cgid is used.
663 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
665 Changes with Apache 2.0.15
667 *) Untangled the buildconf script and eliminated the need for build's
668 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
669 libtool muck that is now under srclib/apr/build. [Roy Fielding]
671 *) Win32: Don't accept more connections than we have worker threads
675 *) Fix bug in the Unix threaded.c MPM that allowed child processes
676 to fork() new child processes.
679 *) Fix a major security problem with double-reverse lookup checking.
680 Previously, a client connecting over IPv4 would not be matched
681 properly when the server had an IPv6 listening socket. PR #7407
682 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
684 *) Change the way the beos MPM handles polling to allow it to stop and
685 restart. Problem was the sockets being polled were being reset by
686 the select call, so once it had accepted a connection it was no
687 longer listening on the UDP socket we use for shutdown instructions.
688 APR needs to be altered, patch on it's way. [David Reid]
690 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
691 on error exit from ap_getline(). Some other code got upset because
692 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
694 *) Handle ap_discard_request_body() being called more than once.
695 [Greg Ames, Jeff Trawick]
697 *) Get rid of an inadvertent close of file descriptor 2 in
698 mod_mime_magic. [Greg Ames, Jeff Trawick]
700 *) Add a hook, create_request. This hook allows modules to modify
701 a request while it is being created. This hook is called for all
702 request_rec's, main request, sub request, and internal redirect.
703 When this hook is called, the the r->main, r->prev, r->next
704 pointers have been set, so modules can determine what kind of
705 request this is. [Ryan Bloom]
707 *) Cleanup the build process a bit more. The Apache configure
708 script no longer creates its own helper scripts, it just
710 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
712 *) Stop the forced downgrade of the connection to HTTP/1.0 for
713 proxy requests. [Graham Leggett]
715 *) Avoid using sscanf to determine the HTTP protocol number in
716 the common case because sscanf is a performance hog. From
717 Mike Abbot's Accelerating Apache patch number 6.
718 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
720 *) Fix a security exposure in mod_access. Previously when IPv6
721 listening sockets were used, allow/deny-from-IPv4-address rules
722 were not evaluated properly (PR #7407). Also, add the ability to
723 specify IPv6 address strings with optional prefix length on Allow
724 and Deny. [Jeff Trawick]
726 *) Enhance rotatelogs so that a UTC offset can be specified, and
727 the logfile name can be formatted using strftime(3). (Brought
728 forward from 1.3.) [Ken Coar]
730 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
731 DuplicateHandle on an IOCompletionPort (a practice which
732 MS "discourages"). The new model does not rely on associating
733 the completion port with the listening sockets, thus the
734 completion port can be completely managed within the child
735 process. A dedicated thread accepts connections off the network,
736 then calls PostQueuedCompletionStatus() to wake up worker
737 threads blocked on the completion port.
740 *) Bring forward the --suexec-umask option which allows the
741 builder to preset the umask for suexec processes. [Ken Coar]
743 *) Add a -V flag to suexec, which causes it to display the
744 compile-time settings with which it was built. (Only
745 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
747 *) Mod_include should always unset the content-length if the file is
748 going to be passed through send_parsed_content. There is no to
749 determine if the content will change before actually scanning the
750 entire content. It is far safer to just remove the C-L as long
751 as we are scanning it. [Ryan Bloom]
753 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
754 request and not Proxy-Authenticate.
755 [Graham Leggett <minfrin@sharp.fm>]
757 Changes with Apache 2.0.14
759 *) Fix content-length computation. We ONLY compute a content-length if
760 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
761 or we already have all the data. [Ryan Bloom]
763 *) Report unbounded containers in the config file. Previously, a typo
764 in the </container> directive could result in the rest of the config
765 file being silently ignored, with undesired defaults used.
768 *) Make the old_write filter use the ap_f* functions for the buffering.
771 *) Move more code from the http module into the core server. This
772 is core code, basically the default handler, the default input
773 and output filters, and all of the core configuration directives.
774 All of this code is required in order for the server to work, with or
775 without HTTP. The server is closer to working without the HTTP
776 module, although there is still more to do. [Ryan Bloom]
778 *) Fix a number of SGI compile warnings throughout the server. Fix some
779 bad parameters to apr_bucket_read(). Fix a bad statement in
780 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
781 consistently; we were mixing apr_time_t and time_t in invalid ways
782 before. In load_file(), call apr_dso_error() instead of
783 apr_strerror() so that we get a more specific string on some platforms.
784 PR #6980 [Jeff Trawick]
786 *) Allow modules to query the MPM about it's execution profile. This
787 query API can and should be extended in the future, but for now,
788 max_daemons, and threading or forking is a very good start.
789 [Jon Travis <jtravis@covalent.net>]
791 *) Modify mod_include to send blocks of data no larger than 9k.
792 Without this, mod_include will wait until the whole file is parsed,
793 or the first tag is found to send any data to the client.
794 [Paul J. Reder <rederpj@raleigh.ibm.com>]
796 *) Fix mod_info, so that <Directory> and <Location> directives are
797 not displayed twice when displaying the current configuration.
798 [Ryan Morgan <rmorgan@covalent.net>]
800 *) Add config directives to override DEFAULT_ERROR_MSG and
801 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
802 [Dan Rench <drench@xnet.com>]
804 *) Get mod_info building and loading on Win32. [William Rowe]
806 *) Begin to move protocol independant functions out of mod_http. The goal
807 is to have only functions that are HTTP specific in the http directory.
810 Changes with Apache 2.0.13
812 *) Don't assume that there will always be multiple calls to the byterange
813 filter. It is possible that we will need to do byteranges with only
814 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
816 *) Move the error_bucket definition from the http module to the
817 core server. Every protocol will need this ability, not just
820 Changes with Apache 2.0.12
822 *) Modify mod_file_cache to save pre-formatted strings for
823 content-length and last-modified headers for performance.
824 [Mike Abbot <mja@trudge.engr.sgi.com>]
826 *) Namespace protect IOBUFSIZ since it is exposed in the API.
827 [Jon Travis <jtravis@covalent.net>]
829 *) Use "Basic" authentication instead of "basic" in ab, as the spec
830 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
832 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
833 without ever filling it out. This fixes PR 7271.
834 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
835 Cliff Woolley <cliffwoolley@yahoo.com>]
837 *) Add a couple of GCC attribute tags to printf style functions.
838 [Jon Travis <jtravis@covalent.net>]
840 *) Add the correct language tag for interoperation with the Taiwanese
841 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
843 *) Migrate the perchild MPM to use the new apr signal child, and
844 APR thread functions. [Ryan Bloom]
846 *) Close one copy of the CGI's stdout before creating the new process.
847 The CGI will still have stdout, because we have already dup'ed it.
848 This keeps Apache from waiting forever to send the results of a CGI
849 process that has forked a long-lived child process.
850 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
852 *) Remove the rest of the pthreads functions from the threaded MPM.
853 This requires the APR support for a signal thread that was just
856 *) Make mod_dir use a fixup for sending a redirect to the browser.
857 Before this, we were using a handler, which doesn't make much
858 sense, because the handler wasn't generating any data, it would
859 either return a redirect error code, or DECLINED. This fits the
860 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
862 *) Make the threaded MPM use APR threads instead of pthreads.
865 *) Get mod_tls to the point where it actually appears to work in all cases.
868 *) implement --enable-modules and --enable-mods-shared for "all" and
871 *) Move the threaded MPM to use APR locks instead of pthread locks.
874 *) Rename mpmt_pthread to threaded. This is more in line with the
875 fact that mpmt_pthread shouldn't be using pthreads directly, and
876 it is a smaller name that doesn't tie into anything.
879 *) Rename the module structures so that the exported symbol matches
880 the file name, and it is easier to automate the installation
881 process (generating LoadModule directives from the module filenames).
884 *) Remove the coalesce filter. With the ap_f* functions, this filter
885 is no longer needed. [Ryan Bloom]
887 Changes with Apache 2.0.11
889 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
890 added feature of allowing a uid/gid per child process. If no
891 uid/gid is specified, then Perchild behaves exactly like dexter.
894 *) Get perchild building again. [Ryan Bloom]
896 *) Don't disable threads just because we are using the prefork MPM.
897 If somebody wants to compile without threads, they must now add
898 --disable-threads to the configure command line. [Ryan Bloom]
900 *) Begin to move the calls to update_child_status into common code, so
901 that each individual MPM does not need to update the scoreboard itself.
904 *) Allow mod_tls to compile under Unix boxes where openssl has been
905 installed to the system include files.
906 [Gomez Henri <new-httpd@slib.fr>]
908 *) Cleanup the mod_tls configure process. This should remove any need
909 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
910 configure doesn't check that yet. [Ryan Bloom]
912 *) Add a very early prototype of SSL support (in mod_tls.c). It is
913 vital that you read modules/tls/README before attempting to build
916 *) Fix a potential seg fault on all platforms. David Reid fixed this
917 on BEOS, but the problem could happen anywhere, so we don't want
918 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
920 *) Add new LogFormat directive, %D, to log time it takes to serve a
921 request in microseconds. [Bill Stoddard]
923 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
924 SetOutputFilter. This corresponds nicely with the other Set
925 directives, which operate on containers while the Add* directives
926 tend to work directly on extensions. [Ryan Bloom]
928 *) Cleanup the header handling a bit. This uses the apr_brigade_*
929 functions for the buffering so that we don't need to compute
930 the length of the headers before we actually create the header
933 *) Allow filters to buffer data using the ap_f* functions. These have
934 become macros that resolve directly to apr_brigade_*.
937 *) Get the Unix MPM's to do a graceful restart again. If we are going
938 to register a cleanup with ap_cleanup_scoreboard, then we have to
939 kill the cleanup with the same function, and that function can't be
942 *) Install all required header files. Without these, it was not
943 possible to compile some modules outside of the server.
946 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
947 forward from 1.3 to 2.0, we missed a single line, which broke regex
948 aliases. [Ryan Bloom]
950 *) We have a poor abstraction in the protocol. This is a temporary
951 hack to fix the bug, but it will need to be fixed for real. If
952 we find an error while sending out a custom error response, we back
953 up to the first non-OK request and send the data. Then, when we send
954 the EOS from finalize_request_protocol, we go to the last request,
955 to ensure that we aren't sending an EOS to a request that has already
956 received one. Because the data is sent on a different request than
957 the EOS, the error text never gets sent down the filter stack. This
958 fixes the problem by finding the last request, and sending the data
959 with that request. [Ryan Bloom]
961 *) Make the server status page show the correct restart time, and
962 thus the proper uptime. [Ryan Bloom]
964 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
965 should reduce the amount of duplicate code that is required to
966 create CGI processes.
967 [Paul J. Reder <rederpj@raleigh.ibm.com>]
969 *) ap_new_connection() closes the socket and returns NULL if a socket
970 call fails. Usually this is due to a connection which has been
971 reset. [Jeff Trawick]
973 *) Move the Apache version information out of httpd.h and into release.h.
974 This is in preparation for the first tag with the new tag and release
977 *) Begin restructuring scoreboard code to enable adding back in
978 the ability to use IPC other than shared memory.
979 Get mod_status working on Windows again. [Bill Stoddard]
981 *) Make mod_status work with 2.0. This will work for prefork,
982 mpmt_pthread, and dexter. [Ryan Bloom]
984 *) Correct a typo in httpd.conf.
985 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
987 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
989 *) Get the correct IP address if ServerName isn't set and we can't
990 find a fully-qualified domain name at startup.
991 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
993 *) Make mod_cgid work with SuExec. [Ryan Bloom]
995 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
996 'extra' stat's for user/group since they should never occur, and now
997 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
998 volumes. [William Rowe]
1000 *) Adopt apr features to simplify mod_includes. This changes the
1001 behavior of the USER_NAME variable, unknown uid's are now reported
1002 as USER_NAME="<unknown>" rather than the old user#000 result.
1003 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1005 *) Adopt apr features for simplifing mod_userdir, and accept the new
1006 Win32/OS2 exceptions without hiccuping. [William Rowe]
1008 *) Replace configure --with-optim option by using and saving the
1009 environment variable OPTIM instead. This is needed because configure
1010 options do not support multiple flags separated by spaces.
1013 *) Fix some byterange handling. If we get a byte range that looks like
1014 "-999999" where that is past the end of the file, we should return
1015 a PARTIAL CONTENT status code, and return the whole file as one big
1016 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1018 *) Make the error bucket a real meta-data bucket. This means that the
1019 bucket length is 0, and a read returns NULL data. If one of these
1020 buckets is passed down after the headers are sent, this data will
1021 just be ignored. [Greg Stein]
1023 *) The prefork MPM wasn't killing child processes correctly if a restart
1024 signal was received while the process was serving a request. The child
1025 process would become the equivalent of a second parent process. If
1026 we break out of the accept loop, then we need to do die after cleaning
1027 up after ourselves. [Ryan Bloom]
1029 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1030 restarts. [Ryan Bloom]
1032 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1033 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1034 performing very expensive owner, group and permission lookups
1035 and allows the server to function until these apr_finfo_t fields
1036 are implemented under Win32. [William Rowe]
1038 *) Support for typedsafe optional functions - that is functions exported by
1039 optional modules, which, therefore, may or may not be present, depending
1040 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1041 for sample code. [Ben Laurie]
1043 *) filters can now report an HTTP error to the server. This is done
1044 by sending a brigade where the first bucket is an error_bucket.
1045 This bucket is a simple bucket that stores an HTTP error and
1046 a string. Currently the string is not used, but it may be needed
1047 to output an error log. The http_header_filter will find this
1048 bucket, and output the error text, and then return
1049 AP_FILTER_ERROR, which informs the server that the error web page
1050 has already been sent. [Ryan Bloom]
1052 *) If we get an error, then we should remove all filters except for
1053 those critical to serving a web page. This fixes a bug, where
1054 error pages were going through the byterange filter, even though
1055 that made no sense. [Ryan Bloom]
1057 *) Relax the syntax checking of Host: headers in order to support
1058 iDNS. PR#6635 [Tony Finch]
1060 *) Cleanup the byterange filter to use the apr_brigade_partition
1061 and apr_bucket_copy functions. This removes a lot of very messy
1062 code, and hopefully makes this filter more stable.
1065 *) Remove AddModule and ClearModuleList directives. Both of these
1066 directives were used to ensure that modules could be enabled
1067 in the correct order. That requirement is now gone, because
1068 we use hooks to ensure that modules are in the correct order.
1071 *) When SuExec is specified, we need to add it to the list of
1072 targets to be built. If we don't, then any changes to the
1073 configuration won't affect SuExec, unless 'make suexec' is
1074 specifically run. [Ryan Bloom]
1076 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1077 the APR_XTHREAD argument to open a file for consumption by
1078 parallel threads on win32. [William Rowe]
1080 *) Correct a bug in determining when we follow symlinks. The code
1081 expected a stat -1 result, not an apr_status_t positive error.
1082 Also check if the APR_FINFO_USER fields are valid before we
1083 follow the link. [William Rowe]
1085 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1086 mpm_common.c. These functions are only valid on some platforms,
1087 so they should not be in the main-line code. [Ryan Bloom]
1089 *) Remove ap_chdir_file(). This function is not thread-safe,
1090 and nobody is currently using it. [Ryan Bloom]
1092 *) Do not try to run make depend if there are no .c files in the
1093 current directory, doing so makes `make depend` fail.
1096 *) Update highperformance.conf to work with either prefork or
1097 pthreads mpms. [Greg Ames]
1099 *) Stop checking to see if this is a pipelined request if we know
1100 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1101 This keeps us from making an extra read call when serving a 1.0
1102 request. [Ryan Bloom and Greg Stein]
1104 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1105 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1106 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1108 *) Fix the RFC number mentioned when complaining about a missing
1109 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1111 *) Fix an endless loop in ab which occurred when ab was posting
1112 and the server dropped the connection unexpectedly.
1115 *) Fix a segfault while handling request bodies in ap_http_filter().
1116 This problem has been seen with mod_dav usage as well as with
1117 requests where the body was just being discarded. [Jeff Trawick]
1119 *) Some adjustment on the handling and automatic setting (via
1120 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1121 add the capability to specify flags (NOTEST_CFLAGS and
1122 NOTEST_LDFLAGS) which are used to compile Apache, but
1123 not used during the configuration process. Useful for
1124 flags like "-Werror". [Jim Jagielski]
1126 *) Stop using environment variables to force debug mode or
1127 no detach. We now use the -D command line argument to
1128 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1129 [Greg Stein, Ryan Bloom]
1131 *) Change handlers to use hooks. [Ben Laurie]
1133 *) Stop returning copies of filenames from both apr_file_t and
1134 apr_dir_t. We pstrdup the filenames that we store in the
1135 actual structures, so we don't need to pstrdup the strings again.
1138 *) mod_cgi: Fix some problems where the wrong error value was being
1139 traced. [Jeff Trawick]
1141 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1144 *) Add generic hooks. [Ben Laurie]
1146 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1148 *) Fix a segfault caused by mod_ext_filter when the external filter
1149 program does not exist. [Jeff Trawick]
1151 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1152 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1153 was served through mod_charset_lite (or anything else that would
1154 create a transient bucket in this size range). ap_bucket_make_heap()
1155 silently failed (fixed), transient_setaside() discovered it, but
1156 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1158 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1159 is that some browsers send extra lines at the end of POST requests, and
1160 we don't want to delay sending data back to the user just because the
1161 browser isn't well behaved. [Ryan Bloom]
1163 *) Get SuEXEC working again. We can't send absolute paths to suExec
1164 because it refuses to execute those programs. SuEXEC also wasn't
1165 always recognizing configuration changes made using the autoconf
1168 *) Allow the buildconf process to find the config.m4 files in the correct
1169 order. Basically, we can now name config.m4 files as config\d\d.m4,
1170 and we will sort them correctly when inserting them into the build
1171 process. [Ryan Bloom]
1173 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1174 This also allows mod_cgid to use ap_os_create_priviledged_process,
1175 thus allowing for SuExec execution from mod_cgid. Currently, we do
1176 not support everything that standard SuExec supports, but at least
1177 it works minimally now. [Ryan Bloom]
1179 *) Allow SuExec to be configured from the ./configure command line.
1182 *) Update some of the docs in README and INSTALL to reflect some of
1183 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1185 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1186 need to call sendfile again. This gets us serving large files
1187 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1189 *) Get the support programs building cleanly again.
1190 [Cliff Woolley <cliffwoolley@yahoo.com>]
1192 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1193 current directory logic now backs up over bin/ to determine the
1194 server root from the Apache.exe path.
1196 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1197 loadable modules, dynamic libs are all named libfoo.dll, and the
1198 makefile.win populates the include, lib and libexec directories.
1200 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1201 Apache gets IPv6 listening sockets by default. Additionally, the
1202 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1203 numeric address strings (e.g., "Listen [fe80::1]:8080").
1206 *) Modify the install directory layout. Modules are now installed in
1207 modules/. Shared libraries should be installed in libraries/, but
1208 we don't have any of those on Unix yet. All install directories
1209 are modifyable at configure time. [Ryan Bloom]
1211 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1213 *) Get the functions in server/linked into the server, regardless of
1214 which modules linked into the server. This uses the same hack
1215 for Apache that we use for APR and apr-util to ensure all of the
1216 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1217 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1218 the scripts a bit easier.
1221 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1222 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1224 *) Get all of the auth modules to the point that they will install and
1225 be loadable into the server. Our new build/install mechanism expects
1226 that all modules will have a common name format. The auth modules
1227 didn't use that format, so we didn't install them properly.
1230 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1231 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1233 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1235 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1236 after the end of the response. [Ryan Bloom]
1238 *) Get byterange requests working with responses that do not have a
1239 content-length. Because of the way byterange requests work, we have to
1240 have all of the data before we can actually do the byterange, so we
1241 can compute the content-length in the byterange filter.
1244 *) Get exe CGI's working again on Windows.
1247 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1248 they keep track of whether or not their post config hook has been
1249 called before. Instead of a static variable (which is replaced when
1250 the DSO is loaded a second time), use userdata in the process pool.
1253 Changes with Apache 2.0a9
1255 *) Win32 now requires perl to complete the final install step for users
1256 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1257 and installs the conf, htdocs and htdocs/manual directories.
1260 *) Make mod_include use a hash table to associate directive tags with
1261 functions. This allows modules to implement their own SSI tags easily.
1262 The idea is simple enough, a module can insert it's own tag and function
1263 combination into a hash table provided by mod_include. While mod_include
1264 parses an SSI file, when it encounters a tag in the file, it does a
1265 hash lookup to find the function that implements that tag, and passes
1266 all of the relevant data to the function. That function is then
1267 responsible for processing the tag and handing the remaining data back
1268 to mod_include for further processing.
1269 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1271 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1272 fewer parameters: the local and remote socket addresses were removed
1273 from the parameter list because all required information is available
1274 via the APR socket. [Jeff Trawick]
1276 *) Distribution directory structure reorganized to reflect a
1277 normal source distribution with external install targets.
1280 *) The MPMs that need multiple segments of shared memory now create
1281 two apr_shmem_t variables, one for each shared memory allocation.
1282 the problem is that we can't determine how much memory will be required
1283 for shared memory allocations once we try to allocate more than one
1284 variable. The MM code automatically aligns the shared memory allocations,
1285 so we end up needing to pad the amount of shared memory we want based
1286 on how many variables will be allocated out of the shared memory segment.
1287 It is just easier to create a second apr_shmem_t variable, and two
1288 shmem memory blocks.
1291 *) Cleanup the export list a bit. This creates a single unified list of
1292 functions exported by APR. The export list is generated at configure
1293 time, and that list is then used to generate the exports.c file.
1294 Because of the way the export list is generated, we only export those
1295 functions that are valid on the platform we are building on.
1298 *) Enable logging the cookie with mod_log_config
1299 [Sander van Zoest <sander@covalent.net>]
1301 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1304 *) Added lib/aputil/ as a placeholder for utility functions which are not
1305 specific to the Apache HTTP Server (but do not make sense with APR).
1306 The first utility is "apu_dbm": a set of functions to work with DBM
1307 files. This first version can be compiled for SDBM or GDBM databases.
1310 *) Complete re-write of mod_include. This makes mod_include a filter that
1311 uses buckets directly. This has now served the FAQ correctly.
1312 [Paul Reder <rederpj@raleigh.ibm.com>]
1314 *) Allow modules to specify the first filter in a sub_request when
1315 making the sub_request. This keeps modules from having to change the
1316 output_filter immediately after creating the sub-request, and therefore
1317 skip the sub_req_output_filter. [Ryan Bloom]
1319 *) Update ab to accept URLs with IPv6 literal address strings (in the
1320 format described in RFC 2732), and to build Host header fields in
1321 the same format. This allows IPv6 literal address strings to be
1322 used with ab. This support has been tested against Apache 1.3 with
1323 the KAME patch, but Apache 2.0 does not yet work with this format
1324 of the Host header field. [Jeff Trawick]
1326 *) Accomodate an out-of-space condition in the piped logs and the
1327 rotatelogs.c code, and no longer churn log processes for this
1328 condition. [Victor J. Orlikowski]
1330 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1333 Changes with Apache 2.0a8
1335 *) Add a directive to mod_mime so that filters can be associated with
1339 *) Get multi-views working again. We were setting the path_info
1340 field incorrectly if we couldn't find the specified file.
1343 *) Fix 304 processing. The core should never try to send the headers
1344 down the filter stack. Always, just setup the table in the request
1345 record, and let the header filter convert it to data that is ready
1349 *) More fixes for the proxy. There are still bugs in the proxy code,
1350 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1354 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1357 *) APR: Add new apr_getopt_long function to handle long options.
1358 [B. W. Fitzpatrick <fitz@red-bean.com>]
1360 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1361 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1362 hostname resolution/address string parsing and building
1363 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1364 of one of the apr_sockaddr_t structures for a socket. Change
1365 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1367 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1368 I have proxied pages with it, cleanup will commence soon.
1371 *) Make the proxy work with filters. This isn't perfect, because we
1372 aren't dealing with the headers properly. [Ryan Bloom]
1374 *) Do not send a content-length iff the C-L is 0 and this is a head
1375 request. [Ryan Bloom]
1377 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1378 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1380 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1382 *) Get the default_handler to stop trying to deal with HEAD requests.
1383 The idea is to let the content-length filter compute the C-L before
1384 we try to send the data. If we can get the C-L correctly, then we
1385 should send it in the HEAD response.
1388 *) The Header filter can now determine if a body should be sent based
1389 on r->header_only. The general idea of this is that if we delay
1390 deciding to send the body, then we might be able to compute the
1391 content-length correctly, which will help caching proxies to cache
1392 our data better. Any handler that doesn't want to try to compute
1393 the content-length can just send an EOS bucket without data and
1394 everything will just work.
1397 *) Add the referer to the error log if one is available.
1398 [Markus Gyger <mgyger@itr.ch>]
1400 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1401 change, the root of the configuration tree has been exposed to modules
1403 [Ryan Morgan <rmorgan@covalent.net>]
1405 *) Get the core_output_filter to use the bucket interface directly.
1406 This keeps us from calling the content-length filter multiple times
1407 for a simple static request.
1410 *) We are sending the content-type correctly now.
1411 [Ryan Bloom and Will Rowe]
1413 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1414 a bogus bytes-sent value when the only thing being sent was trailers
1415 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1417 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1418 hints file to determine which platforms define
1419 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1422 *) APR: add apr_get_home_directory() [Jeff Trawick]
1424 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1426 *) Not all platforms have INADDR_NONE defined by default. Apache
1427 used to make this check and define INADDR_NONE if appropriate,
1428 but APR needs the check too, and I suspect other applications will
1429 as well. APR now defines APR_INADDR_NONE, which is always a valid
1430 value on all platforms.
1431 [Branko Èibej <brane@xbc.nu>]
1433 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1434 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1436 *) Relax the syntax checking of Host: headers in order to support
1437 iDNS. PR#6635 [Tony Finch]
1439 *) When reading from file buckets we convert to an MMAP if it makes
1440 sense. This also simplifies the default handler because the
1441 default handler no longer needs to try to create MMAPs.
1444 *) BUFF has been removed from the main server. The BUFF code will remain
1445 in the code until it has been purged from the proxy module as well.
1448 *) Byteranges have been completely re-written to be a filter. This
1449 has been tested, and I believe it is working correctly, but it could
1450 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1451 the output from 1.3, the only difference being that 1.3 includes
1452 a content-length in the response, and this does not.
1455 *) APR read/write functions and bucket read functions now operate
1456 on unsigned integers, instead of signed ones. It doesn't make
1457 any sense to use signed ints, because we return the error codes,
1458 so if we have an error we should report 0 bytes read or written.
1461 *) Always compute the content length, whether it is sent or not.
1462 The reason for this, is that it allows us to correctly report
1463 the bytes_sent when logging the request. This also simplifies
1464 content-length filter a bit, and fixes the actual byte-reporing
1465 code in mod_log_config.c
1468 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1469 it says, because it was only used by EOS and FLUSH buckets. Since
1470 neither of those are required at the end of a brigade, this was
1471 really signifying FLUSH_THE_DATA, but that can be determined better
1472 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1473 buckets now return a length of 0, which is actually the amount of data
1474 read, so they make more sense.
1477 *) Allow the core_output_filter to save some data past the end of a
1478 request. If we get an EOS bucket, we only send the data if it
1479 makes sense to send it. This allows us to pipeline request
1480 responses. As a part of this, we also need to allocate mmap
1481 buckets out of the connection pool, not the request pool. This
1482 allows the mmap to outlive the request.
1485 *) Make blocking and non-blocking bucket reads work correctly for
1486 sockets and pipes. These are the only bucket types that should
1487 have non-blocking reads, because the other bucket types should
1488 ALWAYS be able to return something immediately.
1491 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1492 server, but use Ctrl+Break to initiate a graceful restart
1493 instead of duplicating behavior. [John Sterling]
1495 *) Patch mod_autoindex to set the Last-Modified header based on
1496 the directory's mtime, and add the ETag header. [William Rowe]
1498 *) Merge the 1.3 patch to add support for logging query string in
1499 such a way that "%m %U%q %H" is the same as "%r".
1502 *) Port three log methods from mod_log_config 1.3 to 2.0:
1503 CLF compliant '-' byte count, method and protocol.
1506 *) Add a new LogFormat directive, %c, that will log connection
1507 status at the end of the response as follows:
1508 'X' - connection aborted before the response completed.
1509 '+' - connection may be kept-alive by the server.
1510 '-' - connection will be closed by the server.
1513 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1514 Unicode file names and paths for Win32, and tag the Content-Type
1515 from mod_autoindex to reflect that charset if the the feature
1516 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1518 *) Compute the content length (and add appropriate header field) for
1519 the response when no content length is available and we can't use
1520 chunked encoding. [Jeff Trawick]
1522 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1523 so that content input filters get dechunked data when using
1524 the default handler. Also removed REQUEST_CHUNKED_PASS.
1527 *) Add mod_ext_filter as an experimental module. This module allows
1528 the administrator to use external programs as filters. Currently,
1529 only filtering of output is supported. [Jeff Trawick]
1531 *) Most Apache functions work on EBCDIC machines again, as protocol
1532 data is now translated (again). [Jeff Trawick]
1534 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1535 the EBCDIC support. They are noops on ASCII machines, so this
1536 type of translation doesn't have to be surrounded by #ifdef
1537 CHARSET_EBCDIC. [Jeff Trawick]
1539 *) Fix mod_include. tag commands work again, and the server will
1540 send the FAQ again. This also allows mod_include to set aside
1541 buckets that include partial buckets.
1542 [Ryan Bloom and David Reid]
1544 *) Add suexec support back. [Manoj Kasichainula]
1546 *) Lingering close now uses the socket directly instead of using
1547 BUFF. This has been tested, but since all we can tell is that it
1548 doesn't fail, this needs to be really hacked on.
1551 *) Allow filters to modify headers and have those headers be sent to
1552 the client. The idea is that we have an http_header filter that
1553 actually sends the headers to the network. This removes the need
1554 for the BUFF to send headers.
1557 *) Charset translation: mod_charset_lite handles translation of
1558 request bodies. Get rid of the xlate version of ap_md5_digest()
1559 since we don't compute digests of filtered (e.g., translated)
1560 response bodies this way anymore. (Note that we don't do it at
1561 all at the present; somebody needs to write a filter to do so.)
1564 *) Input filters and ap_get_brigade() now have a input mode parameter
1565 (blocking, non-blocking, peek) instead of a length parameter.
1568 *) Update the mime.types file to the registered media types as
1569 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1572 *) Namespace protect some macros declared in ap_config.h
1575 *) Support HTTP header line folding with input filtering.
1578 *) Mod_include works again. This should still be re-written, but at
1579 least now we can serve an SHTML page again.
1582 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1583 to both the BUFF and the socket in the conn_rec. Functions that
1584 want to use the BUFF can, functions that want to use the socket,
1585 can. They point to the same place.
1588 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1589 [Tomas "Ögren" <stric@ing.umu.se>]
1591 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1592 associated pool goes away. (APR pipes on OS/2 were already had this
1593 logic.) This resolvs a fatal file descriptor leak with CGIs.
1596 *) The final line of the config file was not being read if there was
1597 no \n at the end of it. This was caused by apr_fgets returning
1598 APR_EOF even though we had read valid data. This is solved by
1599 making cfg_getline check the buff that was returned from apr_fgets.
1600 If apr_fgets return APR_EOF, but there was data in the buf, then we
1601 return the buf, otherwise we return NULL.
1604 *) Piped logs work again in the 2.0 series.
1607 *) Restore functionality broken by the mod_rewrite security fix:
1608 rewrite map lookup keys and default values are now expanded
1609 so that the lookup can depend on the requested URI etc.
1610 PR #6671 [Tony Finch]
1612 *) Tighten up the syntax checking of Host: headers to fix a
1613 security bug in some mass virtual hosting configurations
1614 that can allow a remote attacker to retrieve some files
1615 on the system that should be inaccessible. [Tony Finch]
1617 *) Add a pool bucket type. This bucket is used for data allocated out
1618 of a pool. If the pool is cleaned before the bucket is destroyed, then
1619 the data is converted to a heap bucket, allowing it to survive the
1623 *) Add a flush bucket. This allows modules to signal that the filters
1624 should all flush whatever data they currently have. There is no way
1625 to actually force them to do this, so if a filter ignores this bucket,
1626 that's life, but at least we can try with this.
1629 *) Add an output filter for sub-requests. This filter just strips the
1630 EOS bucket so that we don't confuse the main request's core output
1631 filter by sending multiple EOS buckets. This change also makes sub
1632 requests start to send EOS buckets when they are finished.
1635 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1636 makes ap_bucket_destroy a return void, which is okay because it
1637 used to always return APR_SUCCESS, and nobody ever checked its
1638 return value anyway.
1639 [Cliff Woolley <cliffwoolley@yahoo.com>]
1641 *) Remove the index into the bucket-type table from the buckets
1642 structure. This has now been replaced with a pointer to the
1643 bucket_type. Also add some macros to test the bucket-type.
1646 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1647 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1648 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1649 All _VAR_ flavors changes to _DATA to be absolutely clear.
1652 *) Add support for /, //, //servername and //server/sharename
1653 parsing of <Directory> blocks under Win32 and OS2.
1654 [Tim Costello, William Rowe, Brian Harvard]
1656 *) Remove the function pointers from the ap_bucket type. They have been
1657 replaced with a global table. Modules are allowed to register bucket
1658 types and use then use those buckets.
1661 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1662 once we finish writing the request body to the cgi child process;
1663 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1664 worked without this change (for reasons I don't understand), but large
1665 ones didn't. [Jeff Trawick]
1667 *) Remove file bucket specific information from the ap_bucket type.
1668 This has been moved to a file_bucket specific type that hangs off
1669 the data pointer in the ap_bucket type.
1672 *) Input filtering now has a third argument. This is the amount of data
1673 to read from lower filters. This argument can be -1, 0, or a positive
1674 number. -1 means give me all the data you have, I'll deal with it and
1675 let you know if I need more. 0 means give me one line and one line
1676 only. A positive number means I want no more than this much data.
1678 Currently, only 0 and a positive number are implemented. This allows
1679 us to remove the remaining field from the conn_rec structure, which
1683 *) Big cleanup of the input filtering. The goal is that http_filter
1684 understands two conditions, headers and body. It knows where it is
1685 based on c->remaining. If c->remaining is 0, then we are in headers,
1686 and http_filter returns a line at a time. If it is not 0, then we are
1687 in body, and http_filter returns raw data, but only up to c->remaining
1688 bytes. It can return less, but never more.
1689 [Greg Ames, Ryan Bloom, Jeff Trawick]
1691 *) mod_cgi: Write all of the request body to the child, not just what
1692 the kernel would accept on the first write. [Jeff Trawick]
1694 *) Back out the change that moved the brigade from the core_output_filters
1695 ctx to the conn_rec. Since all requests over a given connection
1696 go through the same core_output_filter, the ctx pointer has the
1700 *) Fix another bug in the send_the_file() read/write loop. A partial
1701 send by apr_send would cause unsent data in the read buffer to
1702 get clobbered. Complete making send_the_file handle partial
1703 writes to the network.
1706 *) Fix a couple of type fixes to allow compilation on AIX again
1707 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1709 *) Fix bug in send_the_file() which causes offset to be ignored
1710 if there are no headers to send.
1713 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1714 filter. Useful for supporting Windows 9* with a binary
1715 compiled on Windows NT.
1718 Changes with Apache 2.0a7
1720 *) Reimplement core_output_filter to buffer/save bucket brigades
1721 across multiple calls to the core_filter. The brigade will be
1722 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1723 thresholds are hit or the EOS bucket is received.
1726 *) Create experimental filter (buffer_filter) that coalesces bytes
1727 into one large buffer before invoking the next filter in the
1728 chain. This filter is particularly useful with the current
1729 implementation of mod_autoindex when it inserted above the
1730 chunk_filter. mod_autoindex generates a lot of brigades that
1731 containing buckets holding just a few bytes each. The
1732 buffer_filter coalesces these buckets into a single large bucket.
1735 *) Add apr_sendfile() support into the core_output_filter.
1738 *) Add apr_sendv() support into the core_output_filter.
1741 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1742 [Mike Abbott <mja@sgi.com>]
1744 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1745 make much sense, because Apache uses buckets instead of BUFFs now.
1748 *) send_the_file now falls back to a read/write loop on platforms that
1749 do not have sendfile.
1750 [Ryan Bloom and Brian Havard]
1752 *) Install apachectl correctly, and substitute the proper values so
1753 that it works again. [Ryan Bloom]
1755 *) Better(??) handle platforms that lack sendfile().
1758 *) APR now has UUID generation/formatting/parsing support.
1761 *) Begin the http_filter. This is an input filter that understands
1762 the absolute basic amount required to parse an HTTP Request. The
1763 goal is to be able to split headers from request body before passing
1764 the data back to the other filters.
1767 *) Bring forward from 1.3.13 the config directory implementation
1770 *) install apxs if it is created
1773 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1774 conversions. [William Rowe]
1776 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1777 ap_add_output_filter(). [Jeff Trawick]
1779 *) Multiple build and configuration fixes
1782 -add datadir and localstatedir substitutions
1784 -fix logfilename misspelling
1785 -fix evaluation of installation dir variables and
1786 -replace $foobar by $(foobar) to be usefull in the makefile
1790 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1791 $CC_FOR_BUILD is still missing
1792 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1793 -add missing "AR=@AR@" to severaly Makefile.in's
1794 -cache result for "struct rlimit"
1795 -compile all helper programs with native and cross compiler
1796 and use the native version to generate header file
1797 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1799 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1801 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1803 *) Fix a bug where a client which only sends \n to delimit header
1804 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1805 message. Start working on ebcdic co-existance with input
1807 [William Rowe, Greg Ames]
1809 *) If mod_so is enabled in the server always create libexec, even
1810 if there are no modules installed in this directory. This is a
1811 requirement for APXS to work correctly.
1814 *) Connection oriented output filters are now stored in the
1815 conn_rec instead of the request_rec. This allows us to add the
1816 output filter in the pre-connection phase instead of the
1817 post_read_request phase, which keeps us from trying to write an
1818 error page before we have a filter to write to the network.
1819 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1821 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1822 mmap can be used across multiple buckets (default_handler with
1823 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1824 the mmap itself can't be associated with the bucket.
1827 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1830 *) Radical surgery to improve mod_isapi support under Win32.
1831 Includes a number of newer ServerSupportFunction calls, support
1832 for ReadClient (in order to retrieve POSTs greater than 48KB),
1833 and general bug fixes to more reliably load ISAPI .dll's and
1834 prevent leaking handle resources. Note: There are still
1835 discrepancies between IIS's and Apache's ServerVariables, and
1836 async calls are still not supported. Additional warnings are
1837 logged to facilitate debugging of unsupported ISAPI calls.
1840 *) Add input filtering to Apache. The basic idea for the input
1841 filters is the same as the ideas for output filters. The biggest
1842 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1843 should be called, and the order of execution for the filter itself is
1844 different. When writing an output filter, a brigade is passed in,
1845 and filters operate directly on that brigade, when done, they call
1846 ap_pass_brigade. Input filters are the exact opposite. Because input
1847 is not a push operation, filters first call ap_get_brigade. When this
1848 function returns, the input filter will be left with a valid brigade.
1849 The input filter should then operate on the brigade, and return.
1852 *) Fix building on BSD/OS using its native make. The build system
1853 falls back to the BSD .include directive on that host platform.
1856 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1857 SHA1 and plaintext password encodings. Make feature tests a
1858 bit more flexible. [William Rowe]
1860 *) Charset translation: mod_charset_lite handles output content
1861 translation in a filter. mod_charset_lite no longer ignores
1862 subrequests. A bunch of cruft related to BUFF's support for
1863 translating request and response bodies was removed.
1866 *) Move the addition of the CORE filter to the post_read_request
1867 hook in http_core.c. This removes the need to add the filter in
1868 multiple places and allows for an SSL module to be added much
1869 simpler. [Ryan Bloom]
1871 *) Fix a security problem that affects certain configurations of
1872 mod_rewrite. If the result of a RewriteRule is a filename that
1873 contains expansion specifiers, especially regexp backreferences
1874 $0..$9 and %0..%9, then it may be possible for an attacker to
1875 access any file on the web server. [Tony Finch]
1877 *) Fix a bug where errors that are detected during early request parsing
1878 don't produce visible HTTP error messages at the browser, because
1879 the core_filter wasn't present. [Greg Ames]
1881 *) Provide apr_socklen_t as a portability aid.
1882 [Victor J. Orlikowski]
1884 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1885 as well as a comment arg to the add, adduser and update cmds.
1886 update allows the user to clear or preserve pw/groups/comment.
1887 Fixed a bug in dbmmanage that prevented the check option from
1888 parsing a password followed by :group... text. Corrected the
1889 seed calcualation for Win32 systems, and added -lsdbm support.
1892 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1895 *) Avoid a segfault when parsing .htaccess files. An
1896 uninitialized tree pointer was passed to ap_build_config().
1899 *) Change the way that inet_addr & inet_network are checked for
1900 in APR's configure process to allow BeOS BONE to correctly
1901 find them. With this change BeOS BONE now builds from source
1902 with no problems. [David Reid]
1904 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1905 the end of the parameters to execve() was stored in the wrong
1906 location, overlaying the storage beyond the newargs[] array and
1907 also passing uninitialized storage to execve(), which would
1908 sometimes fail with EFAULT. [Jeff Trawick]
1910 *) Fix a bug parsing configuration file containers. With a sequence
1911 like this in the config file
1913 <IfModule mod_kilroy.c>
1916 <IfModule mod_lovejoy.c>
1921 the second container would be terminated at the blank line due to
1922 sediment in the buffer from reading the prior </IfModule> and an
1923 error message would be generated for the real </IfModule> for the
1924 second container. Also due to this problem, any two characters
1925 could be used for "</" in the close of a container.
1928 *) ap_add_filter prototype changed to remove the ctx pointer. The
1929 pointer still remains in the filter structure, but it can not be
1930 a part of the ap_add_filter prototype. The reason is that when
1931 the core uses AddFilter to add a filter to the stack it doesn't
1932 know how to allocate the ctx pointer, or even how much memory should
1933 be allocated. The filters will have to be responsible for allocating
1934 the ctx memory when they need it.
1937 *) Add an AddFilter directive. This directive takes a list of filters
1938 that should be activated for the requested resource.
1941 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1942 some other platforms). [Jeff Trawick]
1944 *) Modify mod_include to be a filter. Currently, it has only been tested
1945 on actual files, but it should work for CGI scripts too.
1948 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1949 writes. apr_flush() for Unix: handle interrupted writes.
1952 *) NameVirtualHost can now take "*" as an argument instead of
1953 an IP address. This allows you to create a purely name-based
1954 virtual hosting server that does not have any IP addresses in
1955 the configuration file and which ignores the local address
1956 of any connections. PR #5595, PR #4455 [Tony Finch]
1958 *) Fix some compile warnings in mod_mmap_static.c
1959 [Mike Abbott <mja@sgi.com>]
1961 *) Fix chunking problem with CGI scripts. The general problem was that
1962 the CGI modules were adding an EOS bucket and then the core added an
1963 EOS bucket. The chunking filter finalizes the chunked response when it
1964 encounters an EOS bucket. Because two EOS buckets were sent, we
1965 finalized the response twice. The fix is to make sure we only send one
1966 EOS, by utilizing a flag in the request_rec.
1969 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1970 and Win32. Previously, the first read from an apr_file_t set up via
1971 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1973 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1974 bucket, instead of using BUFF's and ap_r*.
1977 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1978 [Mike Abbott <mja@sgi.com>]
1980 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1981 code to use APR file's directly instead of going through BUFFs.
1984 *) Fix compile break on some platforms for mod_mime_magic.c
1985 [John K. Sterling <sterling@covalent.net>]
1987 *) Fix merging of AddDefaultCharset directive.
1988 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1990 *) Minor revamp of the rlimit sections of code. We now test
1991 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1992 is now "available" even if the platform doesn't support
1993 the rlimit family (it's just a noop though). [Jim Jagielski]
1995 *) Migrate the pre-selection of which MPM to use for specific
1996 platforms to hints.m4, which contains (or should contain)
1997 all platform specific "hints". [Jim Jagielski]
1999 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2002 *) Add tables with non-string/binary values to APR.
2005 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2008 *) Update PCRE to version 3.2. [Ryan Bloom]
2010 *) Change the way buckets' destroy functions are called so that
2011 they can be more directly used when changing the type of a
2012 bucket in place. [Tony Finch]
2014 *) Add generic support for reference-counting the resources used by
2015 buckets, and alter the HEAP and MMAP buckets to use it. Change
2016 the way buckets are initialised to support changing the type of
2017 buckets in place, and use it when setting aside TRANSIENT buckets.
2018 Change the implementation of TRANSIENT buckets so that it can be
2019 mostly shared with IMMORTAL buckets, which are now implemented.
2022 Changes with Apache 2.0a6
2024 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2026 *) Add a chunking filter to Apache. This brings us one step closer
2027 to removing BUFF. [Ryan Bloom]
2029 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2030 added to the stack is the last filter to be called. [Ryan Bloom]
2032 *) Apache 2.0 has been completely documented using Scandoc. The
2033 docs can be generated by running 'make docs'. [Ryan Bloom]
2035 *) Add filtered I/O to Apache. This is based on bucket brigades,
2036 Currently the buckets still use BUFF under the covers, but that
2037 should change quickly. The only currently written filter is the
2038 core filter which just calls ap_bwrite. [The Apache Group]
2040 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2041 built with thread support. [Jeff Trawick]
2043 *) Abort configuration if --with-layout was specified and there's
2044 no layout definition file. [Ken Coar]
2046 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2048 *) Add support for extension methods for the Allow response header
2049 field, and an API routine for accessing r->allowed and the
2050 list of extension methods in a unified manner. [Ken Coar]
2052 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2053 [Rob Simonson <simo@us.ibm.com>]
2055 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2056 APACHE_XLATE builds. [Jeff Trawick]
2058 *) A configuration file parsing problem was fixed. When the
2059 configuration file started with an IfModule/IfDefine container,
2060 only the last statement in the container would be retained.
2063 Changes with Apache 2.0a5
2065 *) Perchild is serving pages after passing them to different child
2066 processes. There are still a lot of bugs, but this does work. I
2067 have made requests against the same installation of Apache, and had
2068 different servers use different user IDs to serve the responses.
2069 This change moves to using socketpair instead of an AF_UNIX socket.
2072 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2073 It can't seem to pass between child processes yet, but I think we
2074 are closer now than before. This moves us back to using Unix
2075 Domain Sockets. [Ryan Bloom]
2077 *) libapr functions and types renamed with apr_ prefix.
2078 #include "apr_compat.h" for 1.3.x backwards compat
2081 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2082 return the right information on the local socket address.
2083 [Gregory Nicholls <gnicholls@level8.com>]
2085 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2086 [Gregory Nicholls <gnicholls@level8.com>]
2088 *) Add an option to not detach from the controlling terminal without
2089 going into single process mode. This allows for much easier
2090 debugging of the process startup code. [Ryan Bloom]
2092 *) ab: don't use perror() to report the failure of an APR function.
2095 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2096 scoreboard on graceful restarts.
2099 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2100 An invalid ap_proc_t was passed to ap_create_process().
2103 *) Allow modules to register filters. Those filters are still
2104 never called, but this is a step in the right direction.
2105 [Ryan Bloom and Greg Stein]
2107 *) Register the mod_cgid daemon process for cleanup so that it is
2108 killed at termination if it does not die when the parent gets
2109 SIGTERM. This change is to fix occasional problems where the
2110 process stays around. Bugs in similar logic in mod_rewrite and
2111 mod_include were also fixed. [Jeff Trawick]
2113 *) Fix a bug in the time handling. Basically, we were imploding a time
2114 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2115 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2116 uses those two fields to adjust the time value. Because of the HTTP
2117 spec, both of those values can be zero'ed out safely. This fixes
2118 the bug correctly. [Ryan Bloom]
2120 *) Fix a couple of place in the Windows code where the wrong error
2121 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2123 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2125 *) Added the APR_EOL_STR macro for platform dependent differences in
2126 logfiles and other raw text (such as all APR files). Fixes logfiles
2127 not terminated with cr/lf sequences in Win32. [William Rowe]
2129 *) Move all strings functions in APR to src/lib/apr/strings and create
2130 apr_strings.h for the prototypes. [Ryan Bloom]
2132 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2133 to repeat the syscall until we stop getting EINTR. I noticed a
2134 related problem at termination (SIGTERM) on FreeBSD when using
2135 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2136 implementation work properly with child init. Previously, ap_lock()
2137 was essentially a no-op because all children were using different
2138 locks and thus nobody ever blocked. [Jeff Trawick]
2140 *) The htdocs/ tree has been moved out of the CVS source tree into
2141 a separate area for easier development. This has NO EFFECT on
2142 end-users or Apache installations. [Ken Coar]
2144 *) Integrate the mod_dav module for WebDAV protocol handling. This
2145 adds the dav and dav_fs modules, the SDBM library, and additional
2146 XML handling utilities. [Greg Stein]
2148 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2151 *) Update the lib/expat-lite/ library (bring forward changes from
2152 the Apache 1.3 repository). [Greg Stein]
2154 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2155 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2157 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2158 machines where sendfile is detected, but nobody has written ap_sendfile.
2159 [Dave Hill <ddhill@zk3.dec.com>]
2161 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2163 *) ab would start up more connections than needed, then quit when the
2164 desired number were finished. Also fixed a logic error involving
2165 ab keepalives. [Victor J. Orlikowski]
2167 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2168 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2169 timeouts (i.e, if a timeout was specified, the pipe reverted to
2170 a full blocking pipe). Now the behaviour is more in line with
2171 Unix non-blocking pipes.
2174 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2175 cache open file handles along with accept socket reuse enables
2176 Apache 2.0 to serve non-keepalive requests for static files at
2177 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2178 and Apache 2.0 will serve almost 1200 rps on my system).
2181 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2182 supports two config directives, mmapfile (same behavious as
2183 mod_mmap_static) and cachefile. Use the cachefile directive
2184 to cache open file handles. This directive only works on systems
2185 that have implemented the ap_sendfile API. cachefile works today
2186 on Windows NT, but has not been tested on any flavors of Unix.
2189 *) Cleanup the configuration. With the last few changes the
2190 configuration process automatically:
2191 inherits information about how to build from APR. Allowing
2192 APR to inform Apache that it should or should not use -ldl
2194 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2195 based on the threading model
2197 Apache calls APR's configure process before finishing it's
2198 configuration processing, allowing for more information flow
2203 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2204 with non-zero argument makes the socket non-blocking. BeOS and
2205 OS/2 already worked this way. [Jeff Trawick]
2207 *) ap_close() now calls ap_flush() for buffered files, so write
2208 operations work a whole lot better on buffered files.
2211 *) Fix error messages issued from MPMs which explain where to change
2212 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2215 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2216 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2217 now the way that the blocking state of a pipe is manipulated.
2218 ap_block_pipe() is gone. [Jeff Trawick]
2220 *) Correct the problem where the only local host name that the IP stack
2221 can discover are 'undotted' private names. If no fully qualified
2222 domain name can be identified, the default ServerName will be set to
2223 the machine's IP address string. A warning is always provided if the
2224 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2226 *) Repair problems with config file processing which caused segfault
2227 at init when virtual hosts were defined and which caused ServerName to
2228 be ignored when there was no valid DNS setup. [Jeff Trawick]
2230 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2232 *) Add ap_sendfile implementation for AIX
2233 [Victor J. Orlikowski]
2235 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2236 apr_network_io.h, and apr_thread_proc.h.
2237 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2239 *) Bring the allocation and pool debugging code back into a working
2240 state. This will need to be tested as so far it's only been used on
2243 *) Change configuration command setup to be properly typesafe when in
2244 maintainer mode. Note that this requires a compiler that can initialise
2245 unions. [Ben Laurie]
2247 *) Turn on buffering for config file reads. Part of this was to
2248 repair buffered I/O support in Unix and implement buffered
2249 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2251 *) Win32: Fix problem where UTC offset was not being set correctly
2252 in the access log. Problem reported on news group by Jerry Baker.
2255 *) Fix segfault when reporting this type of syntax error:
2256 "</container> without matching <container> section", where
2257 container is VirtualHost or Directory or whatever.
2260 *) Prevent the source code for CGIs from being revealed when using
2261 mod_vhost_alias and the CGI directory is under the document root
2262 and a user makes a request like http://www.example.com//cgi-bin/cgi
2263 as reported in <news:960999105.344321@ernani.logica.co.uk>
2266 *) Add support for the new Beos NetwOrking Environment (BONE)
2269 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2270 final input char is incomplete; ap_bwrite_xlate() now handles
2271 incomplete final input chars. [Jeff Trawick]
2273 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2274 that a bhalfduplex call occurs before logging or else DNS and
2275 such can delay the last packet of the response. [Dean Gaudet]
2277 *) Some syscall reduction in APR on unix -- don't seek when setting
2278 up an mmap; and don't fcntl() more than once per socket.
2281 *) When mod_cgid is started as root, the cgi daemon now switches
2282 to the configured User/Group (like other httpd processes)
2283 instead of continuing as root. [Jeff Trawick]
2285 *) The prefork MPM now uses an APR lock for the accept() mutex.
2286 It has not been getting a lock at all recently. httpd -V now
2287 displays APR's selection of the lock mechanism instead of the
2288 symbols previously respected by prefork. [Jeff Trawick]
2290 *) Change the mmap() feature test to check only for existence.
2291 The previous check required features not used by Apache.
2294 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2295 sometimes mangled. The len parm to accept() was not
2296 initialized, leading sometimes to an endless loop of failed
2297 accept() calls on OS/390 and anywhere else that failed the call
2298 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2299 instead of declaring it ourselves to fix a compilation problem
2300 on Solaris. [Jeff Trawick]
2302 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2304 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2306 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2308 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2309 initialization if ALLOC_DEBUG is defined; no known symptom
2310 otherwise. [Jeff Trawick]
2312 *) Fix typo in configure script when checking for mod_so. bash
2313 doesn't seem to have a problem but /bin/sh on Solaris does.
2314 Symptom: "./configure: test: unknown operator =="
2317 *) Rebind the Win32 NT and 9x services control into the MPM.
2318 All console, WinNT SCM and Win9x pseudo-service control code is
2319 now wrapped within the WinNT MPM.
2322 *) Make a copy of getenv("PATH") before storing for later use. Some
2323 getenv() implementations use the same storage for successive calls.
2324 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2326 *) Server Tokens work in 2.0 again. This also propogates the change
2327 to allow just the product name in the server string using
2331 Changes with Apache 2.0a4
2333 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2334 won't need to call it. [Greg Ames, Jeff Trawick]
2336 *) Move pre_config hook call to between configuration read and config
2337 tree walk. This allows all modules to implement pre_config hooks
2338 and know that they will be called at an appropriate time.
2341 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2344 *) Add pre-config hooks back to all modules.
2347 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2348 ContentDigest enabled and we can't/don't mmap the file.
2351 *) We now report the correct line number for syntax errors in config
2352 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2354 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2355 related bugs, and changed shmem/locking to use apr API. Shared-mem
2356 is currently disabled, however, because of problems with graceful
2357 restarts. [Ronald Tschalär]
2359 *) Fix corruption of IFS variable in --with-module= handling.
2360 Depending on the user's shell or customization thereof, there
2361 would be errors generating ap_config_auto.h later in the configure
2362 procedure. [Jeff Trawick]
2364 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2365 isn't used (as in 1.3), except that on Unix it is now logged via
2366 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2367 to the error log. [Greg Ames, Jeff Trawick]
2369 *) Add '-D' argument processing for run time configuration defines.
2372 *) Organize http_main.c as independent code, such that no code or
2373 global data is exported from it. WIN32 will dynamically link it
2374 to the server core, so this will prevent mutual dependency.
2377 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2378 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2381 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2382 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2384 *) Add mod_charset_lite for configuring character set translation.
2387 *) Add '-n' option to htpasswd to make it print its user:pw record
2388 on stdout rather than having to frob a text file. [Ken Coar]
2390 *) Fix saferead. Basically, we flush the output buffer if a read on the
2394 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2395 a conversion is single-byte only. [Jeff Trawick]
2397 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2398 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2401 *) Fix some minor errors where pid was being manipulated as an int
2402 instead of the portable pid_t. [Roy Fielding]
2404 *) Fix some error log prints that were printing the pointer to a
2405 structure rather than the pid within the structure.
2406 [Jeff Trawick, Roy Fielding]
2408 *) ab: Fix a command-line processing bug; track bad headers in
2409 err_response; support reading headers up to 2K.
2410 [Ask Bjoern Hansen <ask@valueclick.com>]
2412 *) Fix ap_resolve_env() so that it handles new function added in a prior
2413 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2414 config file.") as well as the constructs used by mod_rewrite.
2415 [Paul Reder <rederpj@raleigh.ibm.com>]
2417 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2419 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2420 APR to perform translation, instead of accessing the hard-coded tables
2421 in 1.3's ebcdic.c. [Jeff Trawick]
2423 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2426 *) Add the ability to hook into the config file reading phase. Basically
2427 if a directive is specified EXEC_ON_READ, then when that directive is
2428 read from the config file, the assocaited function is executed. This
2429 should only be used for those directives that must muck with HOW the
2430 server INTERPRETS the config. This should not be used for directives
2431 that re-order or replace items in the config tree. Those changes should
2432 be made in the pre-config step.
2435 *) Add mod_example to the build system.
2438 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2439 byte character sets. [Jeff Trawick]
2441 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2442 Kraemer and Oliver Reh originally according to the change log).
2445 *) Fix a couple of problems in RFC1413 support (controlled by the
2446 IdentityCheck directive). Apache did not build the request string
2447 properly and more importantly Apache would loop forever if the
2448 would-be ident server dropped the connection before sending a
2449 properly terminated response. [Jeff Trawick]
2451 *) apxs works in 2.0.
2454 *) Reliable piped logs work in 2.0.
2457 *) Introduce a hash table implementation into APR to be used for
2458 replacing tables and other random data structures in Apache.
2461 *) Add some more error reporting to htpasswd in the case of problems
2462 generating or accessing the temporary file. Also, pass in a
2463 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2464 is defined). [Ken Coar]
2466 *) Configure creates config.nice now containing your configure
2467 options. Syntax: ./config.nice [--more-options]
2470 *) Fix various return code problems in APR on Win32. For most of
2471 these, APR was returning APR_EEXIST instead of GetLastError()/
2472 WSAGetLastError(). [Jeff Trawick]
2474 *) Make piped logs work again in version 2.0
2477 *) Add VPATH support to UNIX build system of Apache and APR.
2480 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2484 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2485 Patch submitted to author.
2488 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2489 /sbin in PATH on FreeBSD (all submitted to rse previously)
2492 *) Fix building Pthread-based MPMs on OpenBSD
2493 [Sascha Schumann] PR#26
2495 *) Fix ap_readdir() problem on systems where d_name[] field in
2496 struct dirent is declared with only one byte. (This problem only
2497 affected multithreaded builds.) This caused a segfault during
2498 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2499 least). [Jeff Trawick]
2501 *) Fix some make-portability problems on at least Tru64, Irix
2503 [Sascha Schumann] PR#18, PR#39
2505 *) Add ap_sigwait() to support old-style sigwait() on systems
2506 like OS/390 and UnixWare.
2509 *) Add POSIX-thread flags for more platforms.
2512 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2513 (on Unix, at least) to handle resolver errors. Fix a bug in
2514 the definition of APR_ENOMEM so that ap_strerror() can spit
2515 out the correct error message for it.
2518 Changes with Apache 2.0a3
2520 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2523 *) API: *HOOK* macros now have an AP_ prefix
2526 *) Win32: Eliminate redundant calls to initialize winsock.
2527 [Tim Costello <timcostello@ozemail.com.au>]
2529 *) Fix bugs initializing ungetchar for pipes.
2530 [Chia-liang Kao <clkao@CirX.ORG>]
2532 *) The ab program in the src/support directory is now portable using
2536 *) Support directory is being compiled when the server is built
2539 *) The configure option --with-program-name has been added to allow
2540 developers to rename the executable at configure time. This also
2541 changes the name of the config files to match the executable's name.
2544 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2545 containing version numbers. [Martin Pool]
2547 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2548 Unix; access_log and error_log now created with these perms; non-
2549 Unix is unaffected [Jeff Trawick]
2551 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2552 Replaced more magic numbers with MD5_DIGESTSIZE.
2553 [William Rowe, Roy Fielding]
2555 *) Win32: Get mod_auth_digest compiling and added to the Windows
2556 build environment. Not tested and I'd be suprised if it
2557 actually works. [Bill Stoddard]
2559 *) Revamp the Win32 make environment. Makefiles have been removed and
2560 Apache.dsw created to bring together all the pieces. Create new file
2561 os/win32/BaseAddr.ref to define module base addresses (to prevent
2562 dll relocation at start-up).
2563 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2565 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2566 of the \015, \012, and \015\012 constants with macros.
2567 [Greg Ames <gregames@us.ibm.com>]
2569 *) Add ap_xlate_open() et al for translation of text between different
2570 character sets. The initial implementation requires iconv().
2573 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2574 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2576 *) CGI output is being timed out now.
2579 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2580 is used by the new apr file. There is no reason to create a new file
2581 with the same lifetime as the original file.
2584 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2585 module base addresses. This will help shooting seg faults
2586 in the field. [William Rowe <wrowe@lnd.com>]
2588 *) Update Apache on Windows documentation. Add new document
2589 describing how to compile Apache on Windows.
2590 [William Rowe <wrowe@lnd.com>]
2592 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2593 microseconds instead of seconds. Some storage leaks and other
2594 minor bugs in related code were fixed. [Jeff Trawick]
2596 *) Win32: First cut at getting mod_isapi working under 2.0
2597 [William Rowe <wrowe@lnd.com>]
2599 *) First stab at getting mod_auth_digest working under 2.0
2600 quick change summary:
2601 - moved the random byte generation (ap_generate_random_bytes) into APR
2602 - now uses ap_time_t
2603 - compiles and runs on linux
2605 [Brian Martin <bmartin@penguincomputing.com>]
2607 *) Win32: Move the space stripping of physical service names
2608 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2609 unresolved symbol. Add dependency checking to the
2610 CreateService call to ensure TCPIP and AFP (winsock) is started
2612 [William Rowe <wrowe@lnd.com>]
2614 *) Win32: Add code to perform latebinding on functions that may
2615 not exist on all levels of Windows where Apache runs. This
2616 is needed to allow Apache to start-up on Win95/98. All calls
2617 to non portable functions should be protected with
2618 ap_oslevel checks to prevent runtime segfaults.
2619 [William Rowe <wrowe@lnd.com>]
2621 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2623 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2625 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2626 This addresses PR 1623. Still need to address timing out runaway
2627 CGI scripts. [Bill Stoddard]
2629 *) Win32: Make ap_stat Windows 95/98 friendly
2630 [William Rowe <wrowe@lnd.com>]
2632 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2633 always fail. Need to initialise the dwOSVersionInfoSize member of the
2634 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2637 The patch also enhances ap_get_oslevel (and the associated enum) to
2638 handle selected service packs for NT4, and adds recognition for
2639 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2640 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2641 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2643 *) Get mod_rewrite building and running, and mod_status building for Win NT
2644 [Allan Edwards <ake@raleigh.ibm.com>]
2646 *) Patch to port mod_auth_db to the 2.0 api and also to support
2647 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2648 2.7.7. It should work with version 1 as well but I haven't tested it.
2649 [Brian Martin <bmartin@penguincomputing.com>]
2651 *) Get APR DSO code working under Windows. Includes cross platform
2653 [Tim.Costello@BTFinancialgroup.com]
2655 *) Fix some of the Windows APR time functions.
2658 *) FAQ changes related to tidying up historical documents on the web site.
2659 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2661 *) Move Windows DSO code into APR.
2664 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2665 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2666 at build time. At this point, the server will not compile on Windows because
2667 of the recent DSO commits. Fixing those next.
2668 [Bill Rowe & Bill Stoddard]
2670 *) Added error checking for file I/O APR routines.
2671 [Jon Travis <jtravis@covalent.net>]
2673 *) APR: Don't use the values of resolver error codes for the
2674 corresponding APR error codes. On Unix and Win32, return the
2675 proper APR error code after a resolver error. [Jeff Trawick]
2677 Changes with Apache 2.0a2
2679 *) Renamed the executable back to httpd on all platforms other
2683 *) Allow BeOS to survive restarts, log properly and a few
2684 small things it had problems with due to the way it setup
2685 users and groups. [David Reid]
2687 *) Get mod_rewrite working with APR locks
2688 [Paul Reder <rederpj@raleigh.ibm.com>]
2690 *) Actually remove the sempahore when the lock cleanup routine
2691 is called on BeOS. [David Reid]
2693 *) Clear hook registrations between reads of the config file.
2694 When DSOs are unloaded and re-loaded the old hook pointers may
2695 no longer be valid. This fix eliminates potential segfaults.
2696 [Allan Edwards <ake@raleigh.ibm.com>]
2698 *) Fix a problem with Sigfunc not being defined or bypassed
2699 if sigaction() wasn't found. [Jim Jagielski]
2701 *) Fix the locking mechanism on BSD variants. They now use fcntl
2702 locks. This allows the server to start and serve pages.
2705 *) First cut at getting the Win32 installer to work
2706 [William Rowe <wrowe@lnd.com>]
2708 *) Get htpasswd compiling under Windows
2709 [William Rowe <wrowe@lnd.com>]
2711 *) Change the log message for a bind() failure to show the
2712 interface and port number. [Jeff Trawick]
2714 *) Import the documentation from 1.3.12 and bring parts of it
2715 up-to-date with respect to the changes that have occurred
2719 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2720 now logged correctly on BeOS.
2723 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2724 Makefile.win includes the same user interface as the old
2726 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2728 *) Win32 exec now uses COMSPEC environment string for command
2729 shell path resolution.
2730 [William Rowe <wrowe@lnd.com>] PR#3715
2732 *) Win32: ap_connect() was not returning correct error condition
2734 [Allen Prescott <allen@clanprescott.com>]
2736 *) Win32: ap_open() was broken on Win9x because an NT-specific
2737 flag was passed to CreateFile. ap_puts() added an unnecessary
2739 [Jeff Trawick <trawick@us.ibm.com>]
2741 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2742 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2743 confusing ee/et name and made all extensions language/dialect
2744 rather than country reflecting. Changed example files to
2745 explicit reflect the ISO charset and added a few common
2746 ones to the example config [dirkx]
2748 *) Extend external module capability. To use this, you call
2749 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2752 *) Backported the various "default charset" fixes from 1.3.12,
2753 including the AddDefaultCharset directive. [Jim Jagielski]
2755 *) Added the capability to do ${ENVVAR} constructs in the
2756 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2757 it does this on a line by line basis; i.e. if the envvar
2758 expands to something with spaces you have to protect it
2759 by adding quotes around it (Unless of course you expect it
2760 to contains more than one argument. Alternatively you
2761 can compile it on a per token basis; which is what people
2762 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2763 hampers fancier hacks.
2764 [Dirk-Willem van Gulik]
2766 *) Changed the 'ErrorDocument' syntax in that it NO longer
2767 supports the asymetric
2769 ErrorDocument 301 "Some message
2771 Note the opening " quote, without a closing quote. It now
2772 has either the following syntaxes
2774 ErrorDocument XXX /local/uri
2775 ErrorDocument XXX http://valid/url
2776 ErrorDocument XXX "Some Message"
2778 The recognition heuristic is: if it has a space it
2779 is a message. If it has no spaces and starts with a /
2780 or is a valid URL then treat it that way. Otherwise it
2781 is assumed to be a message.
2783 This breaks backward compatibility but makes live a hell
2784 of a lot easier for GUI's and config file parsers.
2785 [Dirk-Willem van Gulik]
2787 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2788 syntax into a 'on' or 'off' syntax. As it currently is the
2789 only non nesting token which uses NO_ARGS and thus is an
2790 absolute pain for any config interface automation. This
2791 breaks backward compatibility. [Dirk-Willem van Gulik]
2793 *) Add ability to add external modules to the build process. This is
2794 done with --with-module=/path/to/module. Modules can only be added
2795 as static modules at this point.
2798 Changes with Apache 2.0a1
2800 *) Fix FreeBSD 3.3 core dump.
2801 Basically, ap_initialize() needs to get called before
2802 create_process(), since create_process() passes op_on structure
2803 to semop() to get a lock, but op_on isn't initialized until
2804 ap_initialize() calls setup_lock(). Here is a slight
2805 rearrangement to main() which calls ap_initialize() earlier...
2806 [Jeff Trawick <trawick@us.ibm.com>]
2808 *) Enable Apache to use sendfile/TransmitFile API
2809 [Bill Stoddard, David Reid, Paul Reder]
2811 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2815 *) Make file I/O and network I/O writev/sendv APIs consistent.
2816 Eliminate use of ap_iovec_t and use Posix struct iovec.
2817 Use seperate variable on ap_writev to set the number of iovecs
2818 passed in and number of bytes written.
2821 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2822 with ap_create_file_iol(). ap_create_file_iol() requires that
2823 the file be opened prior to the call using ap_open().
2826 *) Port mod_include and mod_cgi to 2.0
2827 [Paul Reder, Bill Stoddard]
2829 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2830 bytes_read/bytes_written is always valid (never -1). Plus
2831 some fixes to buff.c to correct problems introduced by the
2832 errno => ap_status_t changes a while back. Plus a fix to
2833 chunked encoding introduced right at the beginning of 2.0.
2836 *) Revamped UNIX build system to use autoconf and libtool.
2837 [Manoj Kasichainula, Sascha Schumann]
2839 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2841 *) More rigorous checking of Host: headers to fix security problems
2842 with mass name-based virtual hosting (whether using mod_rewrite
2843 or mod_vhost_alias).
2844 [Ben Hyde, Tony Finch]
2846 *) Add back support for UseCanonicalName in <Directory> containers.
2847 [Manoj Kasichainula]
2849 *) Added APLOG_STARTUP log type. This allows us to write an error
2850 message without any of the date and time information. As a part
2851 of this change, I also removed all of the calls to fprintf(stderr
2852 and replaced them with calls to ap_log_error using APLOG_STARTUP
2853 writing to stderr is no longer portable, because we don't direct
2854 stderr to the error log on all platforms.
2857 *) Convert error logging functions to take errno as an argument.
2858 This makes our error logs more portable, because some Windows API's
2859 don't set errno. This change allows us to still output a valid
2860 message on all of our platforms.
2863 *) mod_mime_magic runs in 2.0-dev now.
2864 [Paul Reder <rederpj@raleigh.ibm.com>]
2866 *) sendfile has been added to APR.
2867 [John Zedlewski <zedlwski@Princeton.EDU>]
2869 *) buff.c has been converted to no longer use errno.
2870 [Manoj Kasichainula]
2872 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2873 interface adaption to APR functions did it. [Martin Kraemer]
2875 *) Support DSOs properly on 32-bit HP-UX 11.0
2876 [Dilip Khandekar <dilip@cup.hp.com>]
2878 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2879 [Ralf S. Engelschall]
2881 *) Cleaned APR build environment integration and bootstrap APR
2882 automatically for developers from src/Configure.
2883 [Ralf S. Engelschall]
2885 *) Fixed building of src/support/htpasswd.c
2886 [Ralf S. Engelschall]
2888 *) When generating the Location: header, mod_speling forgot
2889 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2892 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2894 *) Change all pools to APR contexts. This is the first step to
2895 incorporating APR into Apache. [Ryan Bloom]
2897 *) Move "handler not found" warning message to below the check
2898 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2899 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2901 *) Support line-continuation feature in config.option file and
2902 allow the loading of multiple option sections at once via
2903 ``--with-option=<section1>,<section2>,...''
2904 [Ralf S. Engelschall]
2906 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2908 Changes with Apache MPM
2910 *) Use asynchronous AcceptEx() and a completion port to accept and
2911 dispatch connections to threads in Windows NT/2000.
2914 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2917 *) Implement the APACI --with-option facility
2918 (per default used the config.option file).
2919 [Ralf S. Engelschall]
2921 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2923 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2924 Replace pre_connection module call with a register_hook call and
2925 implement pre_connection as a hook. The intent is that these hooks will
2926 be extended to allow Apache to be multi-protocol, and also to allow the
2927 calling order to be specified on a per-hook/per-module basis.
2930 *) Implement mpm_* methods as "modules". Each method gets its own
2931 subdir in src/modules (eg: src/modules/prefork). Selection
2932 of method uses Rule MPM_METHOD. [Jim Jagielski]
2934 *) Port the hybrid server from the apache-apr repository as
2935 mpm_mpmt_pthread. [Manoj Kasichainula]
2937 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2938 amongst the unix MPMs.
2940 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2941 signal handling for the new world order. [Dean Gaudet]
2943 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2944 of alloc.c for now. [Dean Gaudet]
2946 *) Handle partial large writes correctly. [Ben Laurie]
2948 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2949 based on IP/port. [Ben Laurie]
2951 *) Port a bunch of modules to the new module structure.
2952 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2954 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2956 *) Basic restructuring to introduce the MPM concept; includes various
2957 changes to the module API... better described by
2958 docs/initial_blurb.txt. [Dean Gaudet]
2960 Changes with Apache pthreads
2962 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2963 buff operations (generally over a network).
2964 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2966 *) Created http_accept abstraction. Added 4 new functions (not exported):
2967 init_accept(), begin_accepting_requests(), get_request(),
2968 stop_accepting_requests() [Bill Stoddard]
2970 *) Fix to ap_rprintf call that allows mod_info to work properly.
2971 [James Morris <jmorris@intercode.com.au>]
2973 *) user and ap_auth_type fields were moved from connection_rec to
2974 request_rec. [Ryan Bloom]
2976 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2977 needed in a threaded server.
2979 *) Initial pthread implementation from from Dean's apache-nspr code.
2980 [Bill Stoddard, Ryan Bloom]
2983 Changes with Apache 1.3.9
2985 *) Remove bogus error message when a redirect doesn't set Location.
2986 Instead, use an empty string to avoid coredump if the error message
2987 was supposed to include a location. [Roy Fielding]
2989 *) Don't allow configure to include mod_auth_digest unless it is
2990 explicitly requested, even if the user asked for all modules.
2993 *) Translate module names to dll names for OS/2 so that they are no more
2994 than 8 characters long and have an extension of "dll" instead of "so".
2997 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2998 Fix test-compile check to check for randbyte instead of trand32.
2999 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3000 and tweak to make Amaya happier. [Ronald Tschalär]
3002 *) Ensure that the installed expat include files are world readable,
3003 just like the other header files. [Martin Kraemer]
3005 *) Fixed generated AddModule adjustments in APACI's `configure' script
3006 in order to allow (new) modules like mod_vhost_alias to be handled
3007 correctly (which was touched by the adjustments for mod_alias).
3008 [Ralf S. Engelschall]
3010 *) For binary builds, add -R flag to apachectl to work around the lack of
3011 an absolute path to the ./libexec directory where the libhttp.ep file
3012 is needed for SHARED_CORE architectures. [Randy Terbush]
3014 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3015 problem observed by some Win95/98 users where they get CGI script
3016 output sent to the console. [Bill Stoddard]
3018 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3019 routines are now called ap_base64* and are 'plain' (i.e., no
3020 pool access or anything clever). Inside util.c the routines acting
3021 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3022 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3023 now but deprecated. [dirkx]
3025 *) Clean up the base64 and SHA1 additions and make sure they are
3026 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3027 files. [Roy Fielding]
3029 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3030 checking. Allow compiling on VS 6.0. [Randy Terbush]
3032 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3034 *) Use TestCompile to search for the truerand library (rather than blindly
3035 assuming its existence). If it is not found, complain (but do not
3036 exit - yet). [Martin Kraemer]
3038 *) We forgot to add the new exported function names to
3039 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3041 *) Add description of -T command-line option to usage().
3042 [Ralf S. Engelschall]
3044 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3045 searched only AFTER libap has been searched, because libap needs
3046 some symbols from libos. [Martin Kraemer]
3048 *) Fix conflict with original mod_digest related to the symbol of the
3049 module dispatch list (which has to be unique for DSO and follow the
3050 usual conventions for the installation procedure).
3051 [Ralf S. Engelschall]
3053 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3054 for other platforms as well. [Martin Kraemer]
3056 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3057 types by AP_LONG and replace reference to renamed variable 'ubuf'
3058 by 'buffer'. [Martin Kraemer]
3060 Changes with Apache 1.3.8 [not released]
3062 *) Flush the output buffer immediately after sending an error or redirect
3063 response, since the result may be needed by the client to abort a
3064 long data transfer or restart a series of pipelined requests.
3065 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3067 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3068 [Ian Turner <iant@sequent.com>] PR#4735
3070 *) Local struct mmap in http_core.c conflicted with system structure
3071 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3073 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3074 [Ronald Tschalär <ronald@innovation.ch>]
3076 *) Fix a memory leak where the module counts were getting messed
3077 up across restarts. [David Harris <dharris@drh.net>]
3079 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3080 properly in mod_access.
3081 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3083 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3084 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3086 *) PORT: Support for compaq/tandem/com.
3087 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3089 *) Added SHA1 password encryption support to easy migration from
3090 Netscape servers. See support/SHA1 for more information.
3091 Caused the separation of ap_md5.c into md5, sha1 and a general
3092 ap_checkpass.c with just a validate_passwd routine. Added a
3093 couple of flags to support/htpasswd. Some reuse of the to64()
3094 function; hence renamed to ap_to64().
3095 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3097 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3098 with ASCII/EBCDIC conversions in "ident" query.
3099 [David McCreedy <McCreedy@us.ibm.com>]
3101 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3102 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3103 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3105 *) Fix SIGSEGV on some systems because the Vary fix below included
3106 a call to table_do with a variable argument list that was not
3107 NULL terminated. Replaced with better implementation. [Roy Fielding]
3109 Changes with Apache 1.3.7 [not released]
3111 *) The "Vary" response header field is now sanitised right before
3112 the header is sent back to the client. Multiple "Vary" fields
3113 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3114 "Vary: host, negotiate, host, accept-language") are reduced to
3115 single instances. This is a better solution than the force-no-vary
3116 one (which is still valid for clients that can't cope with Vary
3117 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3119 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3121 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3122 least on Linux and FreeBSD for now.
3125 *) Win32: More apache -k restart work. Restarts are now honored
3126 immediately and connections in the listen queue are -not- lost.
3127 This is made possible by the use of the WSADuplicateSocket()
3128 call. The listeners are opened in the parent, duplicated, then
3129 the duplicates are passed to the child. The original listen sockets
3130 are not closed by the parent across a restart, thus the listen queue
3132 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3134 *) Fix handling of case when a client has sent "Expect: 100-continue"
3135 and we are going to respond with an error, but get stuck waiting to
3136 discard the body in the pointless hope of preserving the connection.
3137 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3139 *) Fix 'configure' to work correctly with SysV-based versions of
3140 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3142 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3143 built-in values. Add "-e" option which works like -i but doesn't
3144 install the DSO; useful for editing httpd.conf with apxs. Fix
3145 editing code so that multiple invocations of apxs -a will not
3146 create duplicate LoadModule/AddModule entries; apxs can now be
3147 used to re- enable/disable a module. [Wilfredo Sanchez]
3149 *) Win32: Update the server to use Winsock 2. Specifically, link with
3150 ws2_32.lib rather than wsock32.lib. This gives us access to
3151 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3152 Win 95 users may need to update their TCP/IP stack to pick up
3153 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3154 [Bill Stoddard stoddard@raleigh.ibm.com]
3156 *) Win32: Redirect CGI script stderr (script debug info) into the
3157 error.log when CGI scripts fail. This makes Apache on Win32
3158 behave more like Unix.
3159 [Bill Stoddard stoddard@raleigh.ibm.com]
3161 *) Fixed `httpd' usage display: -D was missing.
3162 [Ralf S. Engelschall] PR#4614
3164 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3165 [Ralf S. Engelschall] PR#4561, PR#4562
3167 *) OS/2: Fix problem with accept lock semaphores where server would die with
3168 "OS2SEM: Error 105 getting accept lock. Exiting!"
3169 [Brian Havard] PR#4505
3171 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3172 [Randy Terbush <randy@covalent.net>]
3174 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3175 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3177 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3178 command potentially _is_ GCC. [Ralf S. Engelschall]
3180 *) Fix apxs build issues on AIX
3181 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3183 *) DocumentRoot Checking: Under previous versions, when Apache
3184 first started up, it used to do a stat of each DocumentRoot to
3185 see if it existed and was a directory. If not, then an error
3186 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3187 does not exist, you will get error messages in error_log. If
3188 the '-t' command line option is used (to check the configuration)
3189 the check of DocumentRoot IS performed. An additional command
3190 line option, '-T', has been added if you want to avoid the
3191 DocumentRoot check even when checking the configuration.
3194 *) Win32: The query switch "apache -S" didn't exit after showing the
3195 vhost settings. That was inconsistent with the other query functions.
3196 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3198 *) Win32: Changed behaviour of apache -k restart.
3199 Previously, the server would drain all connections in the stack's
3200 listen queue before honoring the restart. On a busy server, this
3201 could take hours. Now, a restart is honored almost immediately.
3202 All connections in Apache's queues are handled but connections in
3203 the stack's listen queue are discarded. Restart triggered by
3204 MaxRequestPerChild is unchanged.
3205 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3207 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3208 the accept loop. Good for a 5% performance boost. Cleaned up
3209 parent/child process management code.
3210 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3212 *) Added ceiling on file size for memory mapped files.
3213 [John Giannandrea <jg@meer.net>] PR#4122
3215 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3216 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3217 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3219 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3220 use this at least for Expat. [Ralf S. Engelschall]
3222 *) Allow .module files to specify libraries with Lib:.
3225 *) Allow SetEnvIf[NoCase] to test environment variables as well
3226 as header fields and request attributes. [Ken Coar]
3228 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3229 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3231 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3232 never accepted into any standard, and it opens up certain DoS
3233 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3235 *) TestCompile updated. We can now run programs and output the
3236 results during the Configure process. [ Jim Jagielski]
3238 *) The source is now quad (long long) aware as needed. Specifically,
3239 the Configure process determines the correct size of off_t and
3240 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3241 provides for the 'q' format qualifier (if quads are not available,
3242 'q' is silently "demoted" to long). [Jim Jagielski]
3244 *) When the username or password fed to htpasswd is too long, include the
3245 size limit in the error message. Also report illegal characters
3246 (currently only ':') in the username. Add the size restrictions
3247 to the man page. [Ken Coar]
3249 *) Fixed the configure --without-support option so it doesn't result in
3250 an infinite loop. [Marc Slemko]
3252 *) Piped error logs could cause a segfault if an error occured
3253 during configuration after a restart.
3254 [Aidan Cully <aidan@panix.com>] PR#4456
3256 *) If a "Location" field was stored in r->err_headers_out rather
3257 than r->headers_out, redirect processing wouldn't find it and
3258 the server would core dump on ap_escape_html(NULL). Check both
3259 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3260 if Location isn't set. [Doug MacEachern, Ken Coar]
3262 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3263 of the Expat 1.0.2 distribution. [Greg Stein]
3265 *) Replace regexec() calls with calls to a new API stub function
3266 ap_regexec(). This solves problems with DSO modules which use the regex
3267 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3269 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3270 environment variables can be set according to the protocol version
3271 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3273 *) Add DSO support for OpenStep (Mach 4.2) platform.
3274 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3276 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3277 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3279 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3280 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3282 *) Better DSO flags recognition on NetBSD platforms using ELF.
3283 [Todd Vierling <tv@pobox.com>] PR#4310
3285 *) Always log months in english format for %t in mod_log_config.
3286 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3288 *) Support for server-parsed and multiview-determined ReadmeName and
3289 HeaderName files in mod_autoindex. Removed the restriction on
3290 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3291 routines will deal with the access issues. (It's now possible to
3292 have {site|group|project|customer|...} wide readmes and headers.)
3293 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3296 *) When stat() fails, don't assume anything about the contents of
3297 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3299 *) It's OK for a semop to return EINTR, just loop around and try
3300 again. [Dean Gaudet]
3302 *) Fix configuration engine re-entrant hangups, which solve a
3303 handful of problems seen with mod_perl <Perl> configuration sections
3304 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3306 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3307 by default when building with APACI; allow for platform-specific
3308 variable defaults in configure. [Wilfredo Sanchez]
3310 *) Do setgid() before initgroups() in http_main; some platforms
3311 zap the grouplist when setgid() is called. This was fixed in
3312 suexec earlier, but the main httpd code missed the change.
3313 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3315 *) Add recognition of .tgz as a gzipped tarchive.
3316 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3318 *) mod_include's fsize/flastmod should allow only relative paths, just
3319 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3321 *) OS/2: Add support for building loadable modules using DLLs.
3324 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3327 *) Fix minor but annoying bug with the test for Configuration.tmpl
3328 being newer than Configuration so that it is less likely to fail
3329 when using APACI and shadow sources. [Wilfredo Sanchez]
3331 *) PORT: Add initial support for Mac OS (versions 10.0 and
3332 greater). Use Mac OS X Server layout for now. Clean up dyld code
3333 in unix/os.c, and don't install the dyld error handlers, which
3334 are no longer needed in Mac OS. [Wilfredo Sanchez]
3336 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3337 locations to appropriate ones for user-built (as opposed to
3338 system) installs. [Wilfredo Sanchez]
3340 *) Modify mod_autoindex's handling of AddDescription so that the
3341 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3343 *) Add functionality to the install-bindist.sh script created by
3344 binbuild.sh to use tar when copying distribution files to the
3345 serverroot. This allows upgrading an existing installation
3346 without nesting the new distribution in the old.
3348 install-bindist.sh now detects the local perl5 path to install
3349 apxs and dbmmanage with proper path to perl interpreter.
3351 Add an install-binsupport target which copies the source files
3352 for apxs and dbmmanage to bindist to allow these scripts to
3353 be properly installed relative to the destination serverroot.
3354 [Randy Terbush, Covalent Technologies, randy@covalent.net]

3369 have assurance about how string manipulators (e.g., tr) will
3370 function. [Ken Coar] PR#1630
3372 *) Add a directive to allow customising of the tracking cookie name.
3373 [Ken Coar] PR#2921, 4303
3375 *) Add "force-no-vary" envariable to allow servers to work around
3376 clients that choke on "Vary" fields in the response header.
3377 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
3379 *) Fixed a bug in mod_dir that causes a child process will infinitely

3381 value of the DirectoryIndex directive is a single dot. Also likely
3382 to happen for anyother values of DirectoryIndex that will map back

3428 any output unless a sufficient portion of the compressed
3429 file is input. Change to pass the entire file -- but
3430 only read 4k of output.
3431 [Marcin Cieslak <saper@system.pl>] PR#4097
3433 *) "IndexOptions None" generated extra spaces at the end of each

3437 redirects. [Jose KAHAN <kahan@w3.org>] PR#3910, 3806, 3575
3439 *) When padding the name with spaces for display, mod_autoindex would

3460 *) Prevent clobbering saved IFS values in APACI. [Jim Jagielski]
3462 *) Fix buffer overflows in ap_uuencode and ap_uudecode pointed out
3463 by "Peter 'Luna' Altberg <peter@altberg.nu>" and PR#3422
3464 [Peter 'Luna' Altberg <peter@altberg.nu>, Ronald Tschalär]
3466 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
3469 *) Correct an apparent typo: on the Windows and MPE platforms, the
3470 htpasswd utility was limiting passwords to only 8 characters.
3473 *) EBCDIC platforms: David submitted patches for two bugs in the
3474 MD5 digest port for EBCDIC machines:
3475 a) the htdigest utility overwrote the old contents of the digest file
3476 b) the Content-MD5 header value (ContentDigest directive) was wrong
3477 when the returned file was not converted from EBCDIC, but was a
3478 binary (e.g., image file) in the first place.
3479 [David McCreedy <mccreedy@us.ibm.com>]
3481 *) support/htpasswd now permits the password to be specified on the
3482 command line with the '-b' switch. This is useful when passwords
3483 need to be maintained by scripts -- particularly in the Win32
3484 environment. [Ken Coar]
3486 *) Win32: Win32 multiple services patch. Added capability to install and
3487 run multiple copies of apache as individual services.
3490 apache -n apache1 -i -f c:/httpd.conf
3491 Installs apache as service 'apache1' and associates c:/httpd.conf
3494 Starts apache1 service.
3496 Stops apache1 service
3499 apache -n apache2 -i
3500 Installs apache as service 'apache2'. httpd.conf is located under
3501 the default server root (/apache/conf/httpd.conf).
3503 Starts apache2 service.
3506 apache -n apache3 -i -d c:/program files/apache
3507 Install apache as service 'apache3' and sets server root to
3508 c:/program files/apache.
3511 apache -n apache2 -k restart
3512 Restart apache2 service
3514 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
3516 *) Correct the signed/unsigned character handling for the MD5 routines;
3517 mismatches were causing compilation problems with gcc -pedantic and
3518 in the TPF cross-compilation. [Ken Coar]
3520 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3521 a roughly 5 fold speed up. [Brian Havard]
3523 *) proxy ftp: instead of using the hardwired string "text/plain" as
3524 a fallback type for files served by the ftp proxy, use the
3525 ap_default_type() function to determine the configured type.
3526 This allows for special configurations like
3527 <Directory proxy:ftp://some.host>
3528 DefaultType gargle/blurb
3530 Additionally, add the Content-Encoding: header to FTP proxy replies
3531 when the encoding is defined (by the AddEncoding directive).
3532 Because it was missing, it was almost impossible to browse compressed
3533 files using the FTP proxy (works now perfectly in Communicator).
3534 The ftp proxy now also returns the Date: and Server: header lines (if not
3535 much else... This code is "somewhat" broken) like normal requests do.
3538 *) Be more smart in APACI's configure script when determining the UID/GID
3539 for User/Group directives and use the determined UID/GID to initialize
3540 the permissions on the proxycachedir.
3541 [Dirk-Willem van Gulik, Ralf S. Engelschall]
3543 *) Changed the forking-prior-to-cleanup in the proxy module to first
3544 check wether it actually needs to collect garbage. This reduces
3545 the number of fork()s from one/request to just the odd one an hour.
3546 [Dirk-Willem van Gulik]
3548 *) Added proxy, auth and header support to src/support/ab.c. Added a
3549 README file to src/support/

3555 *) Add support for DSO module compilation on BSD/OS 3.x.
3556 [Randy Terbush, Covalent Technologies]
3558 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
3559 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf
3560 option) were substituted with $(TARGET).conf, etc. Same for other strings
3561 with dots where the dot wasn't matched as plain text.

3569 Changes with Apache 1.3.6
3571 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
3573 Changes with Apache 1.3.5 [not released]
3575 *) M_INVALID needed a value within the scope of METHODS so that unknown
3576 methods can be access controlled. [Roy Fielding] PR#3821
3578 *) Added PassAllEnv; makes server's entire environment available
3579 to CGIs and SSIs executed within directive's scope. [Ken Coar]
3581 *) ap_uuencode() always added two trailing '='s and encoding of
3582 8 bit characters on a machine with signed char may produced
3583 incorrect results. Additionally ap_uuencode() should now
3584 work correctly on EBCDIC platforms.
3585 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
3587 *) WIN32: Binary installer now runs the configuration DLL before
3588 the reboot prompt (which is only given if MSVCRT.DLL system
3589 DLL is new or updated). This should avoid the configuration
3590 directory being empty after installation. [Paul Sutton]
3591 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

3595 the Apache service on NT. [Paul Sutton] PR#3741
3597 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
3599 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
3600 have been reported with flock() locking (probably related to kernel
3601 version). [Dean Gaudet] PR#2723, 3531
3603 *) Using APACI, the main config file (usually httpd.conf) was
3604 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez

3614 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3615 for 8-bit safeness. [Dean Gaudet]
3617 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3618 because SPARCs have a small machine-specific maximum size for the Global
3619 Offset Table which is often exceeded when compiling one of the larger
3620 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3622 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
3623 DSO/DLL section because it's a directive from mod_status and isn't
3624 available before the DLL of mod_status is loaded.

3637 [John Tobey <jtobey@banta-im.com>] PR#3983
3639 *) Let APACI's configure script correctly complain for unknown --enable-XXX
3640 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
3642 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
3643 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
3644 possible buffer overflows. [Ralf S. Engelschall]
3646 *) Remove no longer used non-API function ap_single_module_init().
3647 [Ralf S. Engelschall]
3649 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
3652 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
3653 to make platform installations easier. [Wilfredo Sanchez]
3655 *) In configure, do not append the target name to the directory path if
3656 the path already contains "apache". [Ralf S. Engelschall]
3658 *) SIGPIPE is now ignored by the server core. The request write routines
3659 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3660 correctly check for output errors and mark the connection as aborted.
3661 Replaced many direct (unchecked) calls to ap_b* routines with the
3662 analogous ap_r* calls. [Roy Fielding]
3664 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3665 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3666 Furthermore map lookups for non-existent keys are now cached as well.
3667 Additionally "txt" maps are now parsed with simple string functions
3668 instead of using ap_pregcomp(). As a side effect a bug that prevented
3669 the usage of keys containing the "," character was fixed.
3670 The changes drastically improve the performance when large rewrite maps
3672 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
3674 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
3675 other than GET, and const'd the definition of method in request_rec.
3678 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
3680 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3681 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3683 *) Add %V to mod_log_config, this logs the hostname according to the
3684 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3685 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3687 *) Add support for \n and \t to mod_log_config, can be used to produce
3688 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3690 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
3692 *) Added informative error messages for failed munmap() and fseek() calls
3693 in http_core.c. [John Bley, Roy Fielding]
3695 *) Added some informative error messages for some failed malloc()
3696 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
3698 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
3699 is removed. This allows <Directory proxy:*> directives to work and
3700 prevents invalid requests from killing the process.
3701 [Brian Havard <brianh@kheldar.apana.org.au>]
3703 *) Reorganised FAQ document.
3704 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
3706 *) src/support/: The ApacheBench benchmark program was overhauled by
3707 David N. Welton: you can now have it generate an HTML TABLE, presumably
3708 for integration into other HTML sources. David updated the ab man page
3709 as well and added some missing descriptions. Thanks!
3710 [David N. Welton <davidw@prosa.it>]
3712 *) Win32: The filename validity checker now allows filenames containing
3713 characters in the range 0x80 to 0xff (for example accented characters).
3714 [Paul Sutton] PR#3890
3716 *) Added conditional logging based upon environment variables to
3717 mod_log_config. mod_log_referer and mod_log_agent
3718 are now deprecated. [Ken Coar]
3720 *) Allow apache acting as a proxy server to relay the real
3721 reason of a failure to a client rather than the "internal
3722 server error" it does currently. The general exposure mechanism
3723 can be triggered by any module by setting the "verbose-error-to"
3724 note to "*"; this allows more than just proxy errors to be exposed.
3725 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3727 *) Moved man pages for ab and apachectrl to section 8.
3728 [Wilfredo Sanchez, Roy Fielding]
3730 *) Added -S option to install.sh so that options can be passed to
3731 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3733 *) Tweak modules Makefile generated by Configure so that it handles
3734 the test case of no modules being selected. [chaz@reliant.com]
3736 *) Added a <LimitExcept method ...> sectioning directive that allows
3737 the user to assign authentication control to any HTTP method that
3738 is *not* given in the argument list; i.e., the logical negation
3739 of the <Limit> directive. This is particularly useful for controlling
3740 access on methods unknown to the Apache core, but perhaps known by
3741 some module or CGI script. [Roy Fielding, Tony Finch]
3743 *) Prevent apachectl from complaining if the PIDFILE exists but
3744 does not contain a process id, as might occur if the server is
3745 being rapidly restarted. [Wilfredo Sanchez]
3747 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3749 *) Entity tag comparisons for If-Match and If-None-Match were not being
3750 performed correctly -- weak tags might cause false positives. Also,
3751 strong comparison wasn't properly enforced in all cases.
3752 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
3754 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
3757 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3758 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3760 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3761 to util.c for parsing an HTTP header field value to extract the next
3762 list item, taking into account the possible presence of nested comments,
3763 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3764 insignificant whitespace and lowercases non-quoted tokens.
3765 [Roy Fielding] PR#2065
3767 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3768 code different from 500. This allows the proxy to, e.g., return
3769 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3771 *) Fix ordering of language variants for the case where the traditional
3772 negotiation algorithm is being used with multiple language variants
3773 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3775 *) Do not round the TCN quality calculation to 5 decimal places,
3776 unlike RFC 2296, because the calculation might need 12 decimal places
3777 to get the right result. [Roy Fielding]
3779 *) Remove unused code to disable transparent negotiation when
3780 negotiating on encoding only, as we now handle encoding too
3781 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3782 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3783 some debugging statements within mod_negotiation. [Koen Holtman]
3785 *) Fixed a rare memory corruption possibility in mod_dir if the index
3786 file is negotiable and no acceptable variant can be found.
3787 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3789 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3790 searching the Win32 registry for script interpreters.
3793 *) Win32: The compiled-in default filename for the error log is now
3794 error.log, which matches the default in the distributed httpd.conf.
3797 *) Win32: Any error messages from -i or -u command line options are now
3798 displayed on the console output rather than sent to the error log.
3799 Also the "Running Apache..." message is not output unless Apache is
3800 going to serve requests. [Paul Sutton]
3802 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3803 and use a private significator ('$apr1$') to mark passwords as
3804 being smashed with our own algorithm. Also abstract the password
3805 checking into a new ap_validate_password() routine. [Ken Coar]
3807 *) Win32: The filename validity checker now allows "COM" but refuses
3808 access to "COM1" through "COM4". This allows filenames such
3809 as "com.name" to be served. [Paul Sutton] PR#3769.
3811 *) BS2000: Adapt to the new ufork() system call interface which will
3812 make subtasking easier on the OSD/POSIX mainframe environment.
3815 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3816 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3818 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
3819 use `.db' instead of `.pag' not only for FreeBSD, but also when
3820 the NDBM library looks like Berkeley-DB based.
3821 [Ralf S. Engelschall] PR#3773
3823 *) Add ability to handle DES or MD5 authentication passwords.
3824 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
3826 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
3828 *) SECURITY: Avoid some buffer overflow problems when escaping
3829 quoted strings. (This overflow was on the heap and we believe
3830 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3832 *) Let src/Configure be aware of CFLAGS options starting with plus
3833 signs as it's the case for the HP/UX compiler.
3834 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3836 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3837 and check to see if the tar we wind up with supports '-h'.
3838 [Jim Jagielski] PR#3671
3840 *) A consistent and conservative style for all shell scripts has been
3841 implemented. Basically, all shell string tests use the traditional
3842 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3843 to protect against bare null variable strings (ie: wrapping both
3844 sides with double quotes and prepending 'x'). 'x' was chosen
3845 because it's more universal and hopefully easier for old shell
3846 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3849 *) The status module now prints out both the main server generation as
3850 well as the generation of each process. Also, the vhost info is
3851 printed with '?notable'. [Jim Jagielski]
3853 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3854 and this makes its functions available to things in src/support.
3857 Changes with Apache 1.3.4
3859 *) Renamed macros status_drops_connection to ap_status_drops_connection
3860 and vestigial scan_script_header to ap_scan_script_header_err,
3861 mostly for aesthetic reasons. [Roy Fielding]
3863 *) The query switch "httpd -S" didn't exit after showing the
3864 vhost settings. That was inconsistent with the other query functions.
3867 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3868 filename to the end of the STANDARD_MODULE_STUFF. Its
3869 presence at the beginning prevented reporting of the filename
3870 for modules compiled before 1 January 1999. [Ken Coar]
3872 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3873 to detect and prevent access to special DOS device file names.
3874 [Paul Sutton, Ken Parzygnat]
3876 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3877 and Makefile_win32_debug.txt (debug build) that work on Win95.
3878 Run each of the following from the src directory:
3879 nmake /f Makefile_win32.txt # compiles normal build
3880 nmake /f Makefile_win32.txt install # compiles and installs
3881 nmake /f Makefile_win32.txt clean # removes compiled junk
3882 nmake /f Makefile_win32_debug.txt # compiles debug build
3883 nmake /f Makefile_win32_debug.txt install
3884 nmake /f Makefile_win32_debug.txt clean
3887 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3888 to build binary distributions. [Lars Eilebrecht]
3890 *) IndexOptions SuppressColumnSorting only turned off making
3891 the column headers anchors; you could still change the display
3892 order by manually adding a '?N=A' or similar query string to the
3893 URL. Now SuppressColumnSorting locks in the sort order so
3894 it can't be overridden this way. [Ken Coar]
3896 *) Added IndexOrderDefault directive to supply a default sort order
3897 for FancyIndexed directory listings. [Ken Coar] PR#1699
3899 *) Change the ap_assert macro to a variant that works on all platforms.
3900 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3902 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3903 search for an underscore on dlsym() (as it's already the case
3904 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3906 *) Small fix for mod_env.html: The module was documented as to be _not_
3907 compiled into Apache per default, although it _IS_ compiled into
3908 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3910 *) Instead of fixing a bug in the generation procedure for config.status (a
3911 backslash was missing) we remove the bug together with it's complete
3912 context because the special cases of the past can now no longer occur
3913 because of the recent magic for the --with-layout default.
3914 [Ralf S. Engelschall] PR#3590
3916 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3917 making sure the src/support/ tools are _forced_ to be build last (they
3918 depend on other libraries).
3919 [Markus Theissinger <markus.theissinger@gmx.de>]
3921 *) Fix installation procedure: Now that os-inline.c is actually used (a
3922 recently fixed bug prevented this) we need to also install os-include.c
3923 in addition to os.h into the PREFIX/include/ location or building of
3924 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3926 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3927 allow us to distinguish between a garbled DSO (or even a file which isn't
3928 an Apache module DSO at all) and a DSO which doesn't match the current
3929 Apache API. [Ralf S. Engelschall] PR#3152
3931 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3932 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3933 match case insensitive (this especially avoids nasty patterns like
3934 `[tT][eE][sS][tT]'). Second two additional internal map functions
3935 `escape' and `unescape' were added which can be used to escape/unescape
3936 to/from hex-encodings in URLs parts (this is especially useful in
3937 combination with map lookups).
3938 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3940 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3941 forgotten (because it was a macro) in the symbol renaming process.
3942 [Ralf S. Engelschall]
3944 *) Fix some inconsistencies related to the scopes of directives. The only
3945 user visible change is that the directives `UseCanonicalName' and
3946 `ContentDigest' now use the (more correct) `Options' scope instead of
3947 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3949 *) Using DSO, the Server token was being mangled. Specifically, the
3950 module's token was being added first before the Apache token. This
3951 has been fixed. [Jim Jagielski]
3953 *) Major overhaul of mod_negotiation.c, part 2.
3954 - properly handle "identity" within Accept-Encoding.
3955 - allow encoded variants in RVSA negotiation and let them appear in
3956 the Alternates field using the non-standard "encoding" tag-list.
3957 - fixed both negotiation algorithms so that an explicitly accepted
3958 encoding is preferred over no encoding if "identity" is not
3959 included within Accept-Encoding.
3960 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3961 of large substring sequences.
3962 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3965 *) Major overhaul of mod_negotiation.c, part 1.
3966 - cleanups to mod_negotiation comments and code structure
3967 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3968 support for everything in the upcoming HTTP/1.1
3969 revision (draft-ietf-http-v11-spec-rev-06.txt).
3970 - language tag matching also handles tags with more than 2
3972 - empty Accept, Accept-Language, Accept-Charset headers are
3973 processed correctly; previously an empty header would make all
3974 values acceptable instead of unacceptable.
3975 - allowed for q values in Accept-Encoding
3976 - added support for transparent content negotiation (rfc2295 and
3977 rfc2296) (though we do not implement all features in these drafts,
3978 e.g. no feature negotiation). Removed old experimental version.
3979 - implemented 'structured entity tags' for better cache correctness
3980 (structured entity tags ensure that caches which can deal with Vary
3981 will (eventually) be updated if the set of variants on the server
3983 - this involved adding a vlist_validator element to request_rec
3984 - this involved adding the ap_make_etag() function to the global API
3985 - modified guessing of charsets used by Apache negotiation algorithm
3986 to guess 'no charset' if the variant is not a text/* type
3987 - added code to sort multiviews variants into a canonical order so that
3988 negotiation results are consistent across backup/restores and mirrors
3989 - removed possibility of a type map file resolving to another type map
3990 file as its best variant

4012 *) The hashbang emulation code in ap_execve.c would interpret
4013 #!/hashbang/scripts correctly, but failed to fall back to a

4017 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4020 *) Update APXS manual page: some -q option arguments were missing
4021 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4023 *) Cleanup the command line options: `-?' was documented to show
4024 the usage list but does it with an error because `?' is not a valid
4025 command. OTOH a lot of users expect `-h' to print such a usage list and
4026 instead are annoyed for ages by our huge unreadable list of directives.
4027 So we now changed the command line options this way:
4029 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4030 very similar to the popular linker option.
4032 Intent: while -l gives the small list of modules, -L now gives the
4033 large list of directives implemented by these modules. This is also
4034 consistent with -v (short version info) and -V (large version info).
4036 Intent: it's now the expected option ;-)
4037 The manual page was adjusted accordingly.

4040 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4041 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4043 *) Removed recently introduced bugs and disfigurements in APACI:
4044 o fixed argument line processing: using $args was broken: It was not
4045 initialized and using args="$args $apc_option" and even args="$args
4046 \"$apc_option\"" fails in the second processing round for any arguments
4047 containing whitespaces. The only correct way is to use the construct
4048 "$@" (but not possible here) or iterate _both_ times over the implicit
4049 argument line (no argument to for-loop) which is what we now use.
4050 o make --with-layout=Apache the default without creating
4051 redundancy (copying the --with-layout block in the argument parsing
4052 loop). We achieve this by using the "$@" construct together with the
4053 `set' command to prepend --with-layout=Apache to the command line in
4054 case --with-layout is not used.
4055 o fixed auto-suffix handling now that config.layout exists.
4056 Paths which are auto-suffixed are marked with a trailing plus sign in
4057 config.layout and every path now can be marked this way (not only the
4058 four paths for which we do it currently). Additionally the suffix is
4059 no longer a static one. Instead it's now `/<target>' where <target> is
4060 the argument of the --target option or per default `httpd'.
4061 o allow also tabs (and only spaces) where we match whitespaces
4062 o various fixes and cleanups related to used shell coding style
4063 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4064 o trimmed output of --help to fit into 80 columns
4065 [Ralf S. Engelschall]

4089 *) Make generation of src/Configuration.apaci more robust: It failed to
4090 differenciate between modules when one module name was a postfix of
4091 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4092 just XXX (think about totally non-standard names like "apache_ssl", too).
4093 [Ralf S. Engelschall] PR#3380

4098 [Ralf S. Engelschall] PR#3240
4100 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4101 creates an external package shadow tree in DIR before the local build
4102 shadow tree is generated under DIR. This way one can have the extracted
4103 Apache distribution tree read-only on NFS or CDROM and still build Apache
4104 from these sources. An automatically triggered VPATH-like mechanism is
4105 provided through the TOP variable, too.

4123 They can occur multiple times and their arguments (`xxx') are passed AS
4124 IS to the compiler/linker command. [Ralf S. Engelschall]
4126 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4127 procedure of mod_rewrite: very long keys were truncated.
4128 [Ralf S. Engelschall]
4130 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4131 identifier, currently "Apache" and "GNU" are pre-defined in the file
4132 config.layout. Custom layouts are possible by using FILE:ID as the
4133 argument where the layout ID is taken from FILE.
4135 The config.layout file consists of <Layout ID>..</Layout> sections
4136 where inside those sections "path_variable: path_value" pairs can be
4137 specified. These lines are converted to path_variable='path_value'.
4139 *) Add a DefaultLanguage directive so that files missing a language
4140 extension (e.g., .fr, .de) can be labelled as being some other
4141 default language. DefaultLanguage can appear in <Directory> and
4142 <Files> containers as well as .htaccess files. [Paul Sutton]
4145 *) Fix TARGET configuration when configuring and installing using
4146 APACI configure. TARGET now defines the basename of the configuration
4147 file, startup script, manual page, etc. log_error_core() now reports
4148 the server binary name given by argv[0]. TARGET can now also be defined
4149 with --target=TARGET parameter passed to APACI configure.

4256 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4257 in the Configuration[.apaci] file. Two special and important variants are
4258 supported for the option argument: first BEGIN:foo which permutes module
4259 mod_foo with the begin of the module list, i.e. it `moves' the module to
4260 the begin of the list (gives it lowest priority). And second foo:END
4261 which permutes mod_foo with the end of the module list, i.e. it `moves'
4262 the module to the end of the list (gives it highest priority).

4341 of the protocol processing, which is extra nice because it works
4342 between continuation lines, is almost no cost in the normal case
4343 of no extra whitespace, and saves memory. [Roy Fielding]

4425 that missing files are not confused with unreadable files.
4428 *) The ap_pfopen and ap_pfdopen routines were failing to protect the

4454 who were the top_module. [Doug MacEachern]
4456 *) Add support for Berkeley-DB/2.x (in addition to Berkeley-DB/1.x) to
4457 mod_auth_db to both be friendly to users who wants to use this version
4458 and to avoid problems under platforms where only version 2.x is present.
4459 [Dan Jacobowitz <drow@false.org>, Ralf S. Engelschall]
4461 *) When using ap_log_rerror(), make the error message available to the

4464 *) BS2000 platform only: get rid of the nasty BS2000AuthFile.
4465 You now must define a BS2000Account name for the server User.
4466 This has fewer security implications than the old approach.
4469 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4470 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4471 platform to make the braindead HPUX linker happy. Notice, for the module
4472 DSOs we don't have to use this, because these are loaded manually (and
4473 not via HPUX' dld). [Ralf S. Engelschall] PR#2905, PR#2968

4484 *) Make PrintPath work generically instead of having one version
4485 strictly for OS/2. [Jim Jagielski, Brian Havard]
4487 *) Fix the recently introduced C header file checking: We now use the C
4488 pre-processor pass only (and no longer the complete compiler pass) to
4489 determine whether a C header file exists or not. Because only this way
4490 we're safe against inter-header dependencies (which caused horrible
4491 portability problems). The only drawback is that we now have a CPP
4492 configuration variable which has to be determined first (we do a similar
4493 approach as GNU Autoconf does here). When all fails the user still has
4494 the possibility to override it manually via APACI or src/Configuration.
4495 As a fallback for the header check itself we can directly check the
4496 existance of the file under /usr/include, too.

4529 because our GuessOS is still unaware of Digital UNIX versions and the
4530 -msym is just to optimize the DSO statup time a little bit it's safe and
4531 best when we leave it out now. [Ralf S. Engelschall] PR#2969
4533 *) Fix the ap_log_error_old(), ap_log_unixerr() and ap_log_printf()
4534 functions: First all three functions no longer fail on strings containing
4535 "%" chars and second ap_log_printf() no longer does a double-formatting
4536 (instead it directly passes through the message to be formatted to the
4537 real internal formatting function). [Ralf S. Engelschall] PR#2941
4539 *) Allow "Include" directives anywhere in the server config
4540 files (but not .htaccess files). [Ken Coar] PR#2727
4542 *) The proxy was refusing to serve CONNECT requests except to
4543 port 443 (https://) and 563 (snews://). The new AllowCONNECT
4544 directive allows the configuration of the ports to which a
4545 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4547 *) mod_expires will now act on content that is not sent from a file
4548 on disk. Previously it would never add an Expires: header to
4549 any response that did not come from a file on disk; the only
4550 case where it still doesn't (and can't) add one for that type of
4551 content is if you are using a modification date based setting.

4556 text (in the *ERROR_NOTES envariable) to ErrorDocument 500 scripts.
4559 *) Add NameWidth keyword to IndexOptions directive so that the
4560 width of the filename column is customisable. [Ken Coar, Dean Gaudet]
4563 *) Recognize lowercase _and_ uppercase `uname' results under
4564 SCO OpenServer. [David Coelho <drc@ppt.com>]
4566 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4567 a common problem of (mis-administrated?) IIS servers, make the apache
4568 proxy immune to these errors (and ignore the duplicates, but log
4569 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4571 *) The <IfModule and <IfDefine block starting directives now only
4572 allow exactly one argument. Previously, the optional negation
4573 character '!' could be separated by whitespace without a syntax
4574 error being reported, albeit defeating the IfModule functionality
4575 (enclosed directives would ALWAYS be executed). By using the
4576 stricter syntax, these hard-to-track errors can be avoided.
4579 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4580 cause the standalone FancyIndexing directive to logically OR
4581 into any existing IndexOptions settings rather than wiping
4582 them out. [Ken Coar]
4584 *) Changes in ftp proxy: make URL parsing simpler by using the
4586 + Add display of the "current directory" in cases where it's
4587 different from the supplied path (e.g., ftp://user@host/ lives
4588 in /home/user, not in /, therefore clicking on "../" in the
4589 starting directory might send us to /home/).
4590 + When ftp login fails, (esp. when a user name was part of the
4591 URL already), we now return [401 Unauthorized ] to allow the
4592 browser to pop up an authorization dialog. This makes passwords
4593 slightly less visible (they don't appear in the regular log files)
4594 and implements a functionality that other www proxy servers
4598 *) Triggered by the recent "Via:" header changes, the proxy module would
4599 dump core for replies with invalid headers (e.g., duplicate
4600 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4601 core dump is avoided. Also, broken replies are not cached.
4602 [Martin Kraemer] PR#2914
4604 *) new `GprofDir' directive when compiled with -DGPROF, where gprof can
4605 plop gmon.out profile data for each child [Doug MacEachern]
4607 *) Use the construct ``"$@"'' instead of ``$*'' in the generated
4608 config.status script to be immune against arguments with whitespaces.
4609 [Yves Arrouye <yves@apple.com>] PR#2866
4611 *) Replace the inlined information grabbing stuff for the configuration
4612 adjustment feature (no --without-confadjust) with calls to a new helper
4613 script `buildinfo.sh' which is both more flexible and already proofed to
4614 be more robust against platform differences. This mainly fixes the
4615 recently occured ``sed: command garbled: ...'' problems.

4636 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4637 5 to 10 because there are some users out there who always have 5 to 8
4638 variables in one RewriteRule and had to patch mod_rewrite.h for every
4639 release. So 15 should be now more than enough, even for them. (I never
4640 needed more than 4 in my RewriteRules ;-)
4641 [Ralf S. Engelschall]
4643 *) Make the proxy generate and understand Via: headers
4646 *) Change the proxy to use tables instead of array_headers for
4647 the header lines. [Martin Kraemer]
4649 *) Make sure the config.status file is not overridden when just
4650 ``configure --help'' is used. [Ralf S. Engelschall] PR#2844
4652 *) Split MODULE_MAGIC_NUMBER into _MAJOR/_MINOR numbers. This should
4653 provide a way to trace API changes that add functionality but do
4654 not create a compatibility issue for precompiled modules, etc.
4655 See include/ap_mmn.h for more details. [Randy Terbush]
4657 *) Fix suexec installation under `make install root=xxx' situation.
4658 [Ralf S. Engelschall]
4660 *) Extend the output of the -V switch to include the paths of all
4661 compiled-in configuration files, if they were overridden at
4662 compile time, for least astonishment of the user.
4665 *) When READing a request in ExtendedStatus mode, the "old"
4666 vhost, request and client information is not displayed.
4669 *) STATUS is no longer available. Full status information now
4670 run-time configurable using the ExtendedStatus directive.
4673 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4674 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4675 a function which can be used to perform bulk update operations
4676 on tables in a more efficient manner. [Dean Gaudet]
4678 *) SECURITY: Added compile-time and configurable limits for
4679 various aspects of reading a client request to avoid some simple
4680 denial of service attacks, including limits on maximum request-line
4681 size (LimitRequestLine), number of header fields (LimitRequestFields),
4682 and size of any one header field (LimitRequestFieldsize). Also added
4683 a configurable directive LimitRequestBody for limiting the size of the
4684 request message body. [Roy Fielding]
4686 *) Make status module aware of DNS and logging states, even if
4687 STATUS not defined. [Jim Jagielski]
4689 *) Fix a problem with the new OS/2 mutexes. [Brian Havard]
4691 *) Enhance mod_speling so that CheckSpelling can be used in

4695 ErrorDocument mechanism at runtime [Doug MacEachern]
4697 *) API: new ap_uuencode() function [Doug MacEachern]
4699 *) API: scan_script_header_err_core() now "public" and renamed
4700 ap_scan_script_header_err_core() [Doug MacEachern]
4702 *) The 'status' module will now show the process pid's and their
4703 state even without full STATUS accounting. [Jim Jagielski]
4705 *) Restore the client IP address to the error log messages, this
4706 was lost during the transition from 1.2 to 1.3. Add a new
4707 function ap_log_rerror() which takes a request_rec * and
4708 formats it appropriately. [Dean Gaudet] PR#2661
4710 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4711 whitespace in input lines -- including within quoted strings.
4713 but leading and trailing whitespace should continue to be
4714 stripped [Martin Kraemer]
4716 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4717 the ugly use of an env. variable and use command-line args for
4718 alternate $PATH. Make more like advanced 'type's as well.
4721 *) The IRIXN32 Rule was being ignored. Configure now correctly adds
4722 -n32 only if IRIXN32 says to. [Jim Jagielski, Alain St-Denis
4723 <alain.st-denis@ec.gc.ca>] PR#2736
4725 *) Clean up a warning in mod_proxy. [Ralf S. Engelschall]
4727 *) Renamed __EMX__ (internal define of the gcc port under OS/2) to OS2
4728 following the same idea as "MSVC vs WIN32". Additionally the src/os/emx/
4729 directory was renamed to src/os/os2/ for consistency.
4730 [Brian Havard, Ralf S. Engelschall]
4732 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4733 files (here modules) against other DSO files (here shared libraries).
4734 This is done by determining a subset of LIBS which can be safely used for
4735 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4736 disabled for all platforms to avoid problems with this (experimental)
4737 rule. But we provide it now for those people how ran into problems and
4738 want to came out by forcing linking against DSOs.
4739 [Ralf S. Engelschall] PR#2587
4741 *) Fix suEXEC start message: Has to be of `notice' level to really get

4753 handling loop so that the connection can be properly closed with
4754 lingering_close, thus avoiding a potential TCP reset that would
4755 cause the client to miss the HTTP error response. [Roy Fielding]
4757 *) One more portability fix for APACI shadow tree support: Swap order of awk
4758 and sed in top-level configure script to avoid sed fails on some
4759 platforms (for instance SunOS 4.1.3 and NCR SysV) because of the
4760 non-newline-termined output of Awk. [Ralf S. Engelschall] PR#2729

4873 *) mod_mmap_static will no longer take action on requests unless at
4874 least one "mmapfile" directive is present in the configuration.

4934 *) The APACI libexecdir was not extended with an "apache/" subdir
4935 if the installation prefix didn't already contain "apache", but
4936 it should be because the DSO files are Apache-specific. Now
4937 libexecdir is treated the same way sysconfdir, datadir, localstatedir
4938 and includedir are already treated.

5013 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5014 remove some of the classical hurdles for new users when setting up

5016 user. Package authors can use the --without-confadjust option to disable
5017 these configuration adjustments.
5018 [Ralf S. Engelschall]
5020 *) Added an EXTRA_DEPS configuration parameter which can be used
5021 to add an extra Makefile dependency for the httpd target, for instance
5022 to external third-party libraries, etc.

5026 as <IfModule>..</IfModule> sections) which can be used to skip or process
5027 contained commands dependend of ``-D PARAMETER'' options on the command
5028 line. This can be used to achieve logical conditions like <IfDefine
5029 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5030 and thus especially can be used for conditionally loading DSO-based
5031 modules via LoadModule, etc. [Ralf S. Engelschall]

5038 truncated which forced following HTTP headers to be data in the HTTP
5039 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5042 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5043 in top-level configure script to avoid sed fails on some platforms (for
5044 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5045 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5047 *) Improve performance of directory listings (mod_autoindex) by comparing
5048 integer keys (last-modified and size) as integers rather than converting
5049 them to strings first. Also use a set of explicit byte tests rather
5050 than strcmp() to check for parent directory-ness of an entry. Oh, and
5051 make sure the parent directory (if displayed) is *always* listed first
5052 regardless of the sort key. Overall performance winnage should be good
5053 in CPU time, instruction cache, and memory usage, particularly for large
5054 directories. [Ken Coar]
5056 *) Add a tiny but useful goody to APACI's configure script: The generation
5057 of a config.status script (as GNU Autoconf does) which remembers the used
5058 configure command and hence can be used to restore the configuration by
5059 just re-running this script or for remembering the configuration between
5061 [Ralf S. Engelschall]
5063 *) Add httpd -t (test) option for running configuration syntax tests only.
5064 If something is broken it complains and exits with a return code
5065 non-equal to 0. This can be used manually by the user to check the Apache
5066 configuration after editing and is also automatically used by apachectl
5067 on (graceful) restart command to make sure Apache doesn't die on restarts
5068 because of a configuration which is now broken since the last (re)start.
5069 This way `apachectl restart' can be used inside cronjobs without having
5070 to expect Apache to be falling down. Additionally the httpd -t can be run
5071 via `apachectl configtest'.

5211 spawn_child was obsoleted and moved to compat.h

5215 programs: ap_spawn_child_err() is used and the Win32 case now uses
5216 CreateProcess() instead of a low-level execl() (which caused problems in
5217 the past under Win32).

5220 *) A few cosmetics and trivial enhancements to APXS to make the
5221 generated Makefile more user friendly. [Ralf S. Engelschall]
5223 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5224 was updated to use the normal apache error processing, thereby allowing
5225 proxy errors to be treated by ErrorDocument's as well. For this
5226 purpose, a new module-to-core communication variable "error-notes"
5227 was introduced; the proxy (and possibly other modules) communicates
5228 its error text using this variable. Its content is copied to a new
5229 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5230 The old proxy special error routine ap_proxy_log_uerror()
5231 was replaced by regular ap_log_error() calls, many messages were made

5235 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5238 *) Transform the configure message "You need root privileges for suEXEC"
5239 from a fatal error into a (more friendly) warning because the building
5240 ("make") of Apache we can allow, of course. Root privileges are needed
5241 only for the installation step ("make install"). So make sure the

5304 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5306 *) The proxy cache would store an incorrect content-length in the cached

5308 of the original copy instead of using the cached copy.
5309 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5311 *) The Makefiles assumed that DSO files are build via $(LD). This
5312 is broken for two reasons: First we never defined at least LD=ld
5313 somewhere to make sure this works (it was silently assumed that most Make
5314 provide a built-in LD definition - ARGL!) and second using the generic LD
5315 variable is not the truth. Instead a special variable named LD_SHLIB is
5316 reasonable because although "ld" is usually the default, the command for
5317 building DSO files can be "libtool" or even "cc" on some systems.
5318 [Ralf S. Engelschall]
5320 *) Replace the AddVersionPlatform directive with ServerTokens which
5321 provides for more control over the format of the Server:
5322 header line. SERVER_SUBVERSION is no longer supported;
5323 all module should use the ap_add_version_component()

5330 not retrieved in src/Configure and thus was not useable.
5331 [Ralf S. Engelschall]
5333 *) Various Makefile consistency cleanups:
5334 - make OSDIR also automatically be relative to src/ like INCDIR
5335 - SUBDIRS is now generated in src/Makefile only and not in
5336 Makefile.config because it is a local define for this location.
5337 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5338 any Makefile but make sure that at least the "-K inline" is kept in
5340 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5341 - updated the dependencies theirself
5342 - removed not existing SHLIB variable from "clean" targets
5343 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5344 already exists and OBJS_PIC are also just plain objects and have not
5345 directly to do with "shared" things. The only difference is that they
5346 contain PIC. So OBJS_PIC is the more canonical name.
5347 - Updated the Makefile-dependency lines for OBJS_PIC
5348 - Removed the Makefile-dependency line in Configure to avoid double
5350 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5351 of xxx.lo as GNU libtool does with its PIC objects
5352 - reduce local complexity in modules Makefile.tmpl by moving the last
5353 existing target "depend" to the generation section in Configure, too.
5354 - removed the historical $(SPACER) which was used in the past together
5355 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5356 is no longer needed.
5357 - force the build and run of the gen_xxx programs under main/ as the
5358 first step before building the objects because it looks cleaner
5359 [Ralf S. Engelschall]
5361 *) WIN32: Make Win32 work again after the /dev/null DoS fix.

5368 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5370 *) When opening "configuration" files (like httpd.conf, htaccess
5371 and htpasswd), Apache will not allow them to be non-/dev/null
5372 device files. This closes a DoS hole. At the same time,
5373 we use ap_pfopen to open these files to handle timeouts.
5374 [Jim Jagielski, Martin Kraemer]
5376 *) Apache will now log the reason its httpd children exit if they exit
5377 due to an unexpected signal. (It requires a new porting define,
5378 SYS_SIGLIST, which if defined should point to a list of text
5379 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5381 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5382 like WIN32. Before, Win32 CGI's could have had sporadic failures
5383 if a chdir call from one thread was made between another chdir call
5384 and a spawn in another thread. So, for now don't chdir for CGI scripts
5385 in WIN32. The current CGI "spec" is unclear as to whether it's
5386 necessary. Long-term fix is to either serialize the chdir/spawn combo
5387 or use WIN32 native calls to spawn a process. This temp fix was
5388 necessary to remove this as a showstopper for 1.3's release.
5391 *) Cleanup the suEXEC support in APACI and make it more safe:
5392 1. Add big fat hint in INSTALL about risks and to read the
5393 htdocs/manual/suexec.html document before using the suexec-related
5395 2. Make sure the user has at least provided one --suexec-xxxx option
5396 (specifies suEXEC parameters) in addition to --enable-suexec option.
5397 If only --enable-suexec is given APACI stops with a hint to INSTALL
5398 and htdocs/manual/suexec.html documents.
5399 3. Provide two additional --suexec-xxxx options to make the suEXEC
5400 configuration complete (especially for package maintainers who else
5401 had to patch the source tree) by providing ways to configure minimal
5402 UID/GID and safe PATH, too.
5403 [Ralf S. Engelschall]
5405 *) Cleanup of the `configure --shadow' process:
5406 - make sure the configure script creates its temporary files in the
5407 shadow tree to avoid conflicts with parallel configure runs
5408 - removed unnecessary option "-r" from "rm" call for Makefiles
5409 - make sure the configure scripts creates the shadow-wrapper Makefile
5410 only when no shadow trees already exists
5411 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5412 when no more shadow trees exists
5413 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5414 as fast (in the past it needed 70sec, now it runs just 38sec)
5415 - make sure CVS does not complain about the created files
5416 Makefille.<gnutriple> and directories src.<gnutriple>
5417 [Ralf S. Engelschall]
5419 *) Added the ap_add_version_component() API routine and the
5420 AddVersionPlatform core directive. The first allows modules to
5421 declare themselves in the Server response header field value,
5422 augmenting the SERVER_SUBVERSION define in the Configuration file
5423 with run-time settings (more useful in a loadable-module environment).
5424 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5425 into the server version string. [Ken Coar] PR#2056
5427 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5430 *) Emit the "Accept-Range" header for the default handler.
5431 [Brian Behlendorf] PR#1464
5433 *) Add a note to httpd.conf-dist that apache will on some systems fail
5434 to start when the Group # is set to a negative or large positive value.
5437 *) Make sure the module execution order is correct even when some modules
5438 are loaded under runtime (`LoadModule') via the DSO mechanism:
5439 1. The list of loaded modules is now a dynamically allocated one
5440 and not the original statically list from modules.c
5441 2. The loaded modules are now correctly setup by LoadModule for
5442 later use by the AddModule command.
5443 3. When the DSO mechanism for modules is used APACI's `install'
5444 target now enables all created `LoadModule' lines per default because
5445 this is both already expected by the user _and_ needed to avoid
5446 confusion with the next point and reduces the Makefile.tmpl complexity
5447 4. When the DSO mechanism for modules is used, APACI's `install'
5448 target now additionally makes sure the module list is reconstructed
5449 via a complete `ClearModuleList+AddModule...' entry.
5450 5. The support tool `apxs' now also makes sure an AddModule command
5451 is added in addition to the LoadModule command.
5452 6. The modules.c generation was extended to now contain two
5453 comments to make sure no one is confused by the confusing terminology
5454 of loading/linking (we use load=link+load & link=activate instead of
5455 the obvious load=activate & link=link :-( )
5456 This way now there is no longer a difference under execution time between
5457 statically and dynamically linked modules.
5458 [Ralf S. Engelschall]
5460 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5461 Big Symbol Renaming. [Ralf S. Engelschall]
5463 *) Add a comment to mod_example.c showing the format of a FLAG command
5466 *) Standardized the time format in mod_status to match that of other
5467 places in the code (e.g. DATE_GMT). PR#1551
5469 *) Fix handling of %Z in timefmt strings for those platforms with no time
5470 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5473 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5474 feature compatible with 'UseCanonicalName off' by changing
5475 r->server->server_hostname to ap_get_server_name(). And I changed some
5476 functions which use r->server->port to use ap_get_server_port() instead,
5477 because if there's no Port directive in the config r->server->port is 0.
5480 *) get/set_module_config are trivial enough to be better off inline. Worth
5481 1.5% performance boost. [Dean Gaudet]
5483 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5484 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5487 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5488 the task environment to the unprivileged User id. Otherwise CGI scripts
5489 would have a way to gain super user access. [Martin Kraemer]
5491 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5492 absolute path, only log base name of logging source as is done
5493 in unix. [Martin Kraemer]
5495 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5496 the encoding type from the Accept-Encoding header (if it's there)
5497 and use it in the response, as that's probably what it'll be expecting.
5498 [Ronald.Tschalaer@psi.ch]
5500 *) Fix to mod_alias: translate_alias_redir is dealing with
5501 a URI, not a filename, so the check for drive letters for win32
5502 and emx is not necessary. [Dean Gaudet]
5504 *) WIN32: Allow .cmd as an executable extension.

5507 *) Make Apache header files, and some variables, C++ friendly.
5508 [Michael Anderson's <mka@redes.int.com.mx>]
5510 *) Child processes can now "signal" (by exiting with a status
5511 of APEXIT_CHILDFATAL) the parent process to abort and
5512 shutdown the server if the error in the child process was
5513 fatal enough. [Jim Jagielski]
5515 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5516 [Jim Jagielski] PR#2112
5518 *) Make sure the referer_log and agent_log entries in the default httpd.conf
5519 file are also adjusted for the actual relative installation paths.
5520 [Ralf S. Engelschall] PR#2175
5522 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5524 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5527 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5528 Additionally the checks for finding the vendor DSO library were moved
5529 from mod_so.c to Configure because first it needs $PLAT etc. and second
5530 mod_so already uses an abstraction layer and does not fiddle with the
5531 vendor functions itself.
5532 [Jens-Uwe Mager, Ralf S. Engelschall]
5534 *) PORT: Some optimization defines for NetBSD
5535 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5537 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5538 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5540 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5541 AIX variants should work fine, too. Even AIX 3.x should work). This is
5542 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5543 which we put into a os/unix/os-dso-aix.c file.
5544 [Ralf S. Engelschall]
5546 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5547 that we should use NET_SIZE_T == int but the include files force size_t.
5548 [Ralf S. Engelschall]
5550 *) Fix two bugs in select() handling in http_main.c.
5553 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5554 is unset (as it is in situations like timeouts) where it is unclear
5555 whether errno is set or not. [Martin Kraemer]
5557 *) Just having APACI's localstatedir is too general and not enough for most
5558 of the systems. 1.3b6 again required manual APACI patches by package
5559 maintainers from RedHat and FreeBSD because for their filesystem layout a
5560 little bit more flexibility in configuring the paths is needed. Hence we
5561 provide three additional configure options (--runtimedir, --logfiledir,
5562 --proxycachedir) which now can be used for more granular adjustments if
5563 --localstatedir is not enough to fit the particular needs. As a nice
5564 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5565 [Ralf S. Engelschall]
5567 *) Make the install root for "make install" in APACI's Makefile overrideable
5568 by package authors. This way we are even more friendly to package
5569 maintainers (especially Debian and RedHat) who build for the real prefix
5570 via "configure --prefix=/<real>" but use a different local prefix via
5571 "make root=/tmp/apache install" for rolling the package without bristling
5572 the target location on their system.
5573 [Ralf S. Engelschall]
5575 *) Workaround sed limitations in APACI's configure script by now
5576 substituting in chunks of 50 commands (because for instance HPUX's vendor
5577 sed has a limit of max. 98 commands)
5578 [Ralf S. Engelschall] PR#2136
5580 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5581 [Ralf S. Engelschall] PR#2140
5583 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5584 RENAMING process because they are defined as pre-processor macros instead
5585 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5586 [Ralf S. Engelschall]
5588 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5589 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5590 [Ralf S. Engelschall] PR#2139
5592 *) Various bugfixes and cleanups for the APACI configure script:
5593 o fix IFS handling for _nested_ situation
5594 o fix Perl interpreter search: take first one found instead of last one
5595 o fix DSO consistency check
5596 o print error messages to stderr instead of stdout
5597 o add install-quiet for --shadow situation to Makefile stub
5598 o reduce complexity by avoiding sed-hacks for rule and module list loops
5599 [Ralf S. Engelschall]
5601 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5603 *) Make sure the input field separator (IFS) shell variable is explicitly
5604 initialized correctly before _every_ `for' loop and also restored after
5605 the loops. [Ralf S. Engelschall]
5607 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5608 `magic' files from an existing Apache installation. Because people often
5609 customize these for own MIME and content types.
5610 [Ralf S. Engelschall]

5615 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5616 [Ralf S. Engelschall] PR#2105
5618 *) Let "configure" clear out the users parameters (provided as shell
5619 variables) to avoid side-effects in "src/Configure" when the user
5620 exported them (which is not needed, but some users do it).
5621 [Ralf S. Engelschall] PR#2101
5623 *) Provide backward compatibility from some old src/Configuration.tmpl
5624 parameter names to the canonical Autoconf-style shell variable names. For
5625 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
5626 but a hint message is displayed. [Ralf S. Engelschall]

5629 CGI scripts from an existing Apache installation.
5630 [Ralf S. Engelschall, Jim Jagielski] PR#2084
5632 *) Make `configure --compat' more "compatible" by first
5633 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5634 second by making sure the "avoid-bristling-suffix" /apache is not

5647 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5649 *) If you start apache with the -S command line option it will dump
5650 out the parsed vhost settings. This is useful for folks trying
5651 to figure out what is wrong with their vhost configuration.
5652 (Other dumps may be added in the future.) [Dean Gaudet]
5654 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5655 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5658 *) Because /usr/local/apache is the default prefix the ``configure
5659 --compat'' option no longer has to set prefix, again. This way the
5660 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5662 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5663 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5664 to avoid "discard const" warnings. [Ralf S. Engelschall]
5666 *) If a specific handler is set for a file yet the request still
5667 ends up being handled by the default handler, log an error
5668 message before handling it. This catches things such as trying
5669 to use SSIs without mod_include enabled. [Marc Slemko]
5671 *) Fix error logging for the startup case where ap_log_error() still uses
5672 stderr as the target. Now the default log level is honored here, too.
5673 [Ralf S. Engelschall]
5675 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5676 long" errors when generating the MODULES entry for src/Makefile
5677 [Ben Hyde, Ralf S. Engelschall]
5679 *) Make sure src/Configure doesn't complain about the old directory
5680 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5682 Changes with Apache 1.3b6
5684 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5686 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5687 interface via the similar but proprietary HP/UX shl_xxx-style system
5688 calls. [Ralf S. Engelschall]
5690 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5691 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5692 Make. [Ralf S. Engelschall]
5694 *) ++++ THE BIG SYMBOL RENAMING ++++
5695 To avoid symbol clashes with third-party code compiled into the server,
5696 we globally applied the prefix "ap_" to the following classes of
5698 - Apache provided general functions (e.g., ap_cpystrn)
5699 - Public API functions (e.g., palloc, bgets)
5700 - Private functions which we can't make static (because of
5701 cross-object usage) but should be (e.g., new_connection)
5702 For backward source compatibility a new header file named compat.h was
5703 created which provides defines for the old symbol names and can be used
5704 by third-party module authors.
5707 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5708 problem under SVR4 is that there is no command flag to force the linker
5709 to export the global symbols of the httpd executable therewith they are
5710 available to the DSO's. Instead of problematic hacks like creating a
5711 dummy.so file (containing dummy references to all global symbols) the
5712 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5713 Placing the Apache core code itself into a DSO library named libhttpd.so.
5714 This way the global symbols _HAVE_ to be exported and thus are available
5715 to any manually loaded DSO's under runtime. To reduce the impact to the
5716 user to null we go even further and create a stub httpd executable which
5717 automatically keeps track of the DSO library loading itself and thus
5718 hides the complete mechanism from the user. Although the generation of
5719 this DSO library is automatically triggered for platforms which
5720 essentially need it (mostly all SVR4-derivates) it can be also enabled
5721 manually via the Rule SHARED_CORE. This can be interesting in the future
5722 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5723 features like graceful upgrades, or whatever.
5724 [Ralf S. Engelschall, Martin Kraemer]
5726 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5728 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5729 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5730 conventions while "clean" removes only stuff created by "all" targets,
5731 "distclean" additionally removes the stuff from the configuration
5732 process. This way "make distclean" (hence the name) provides a fresh
5733 source tree as it was for distribution.
5734 [Ralf S. Engelschall]
5736 *) Allow top-level (APACI) Makefile to break on build errors
5737 the same way the src/ subtree Makefiles breaks on them by replacing the
5738 initial APACI sed-subdir-display-kludge with a more clean
5739 variable-passing-solution: variable SDP can optionally hold the subdir
5740 prefix which is consistently used for displaying the subdir movement.
5741 This way even the top-level Makefile can stop correctly on errors as the
5742 user expects. [Ralf S. Engelschall]
5744 *) Fixed ordering of argument checks for RewriteBase directive.
5745 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5747 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5748 indicating that a module is being compiled for dynamic loading. Also
5749 remove #define IS_MODULE from modules and add SHARED_MODULE define
5750 to the mak/dsp files. [Alexei Kosut]
5752 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5753 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5755 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5757 *) Add documentation file and src/Configuration.tmpl entry for the
5758 experimental mod_mmap_static module. Because although it is and marked as
5759 an experimental one it is distributed and thus should be documented and
5760 prepared for configuration the same way as all others modules.
5761 [Ralf S. Engelschall]
5763 *) Add query (-q) option to apxs support tool to be able to manually query
5764 specific settings from apxs. This is needed for instance when you
5765 manually want to access Apache's header files and you need to assemble
5766 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5767 [Ralf S. Engelschall]
5769 *) Now src/Configure uses a fallback strategy for the shared object support
5770 on platforms where no explicit information is available: If a Perl
5771 installation exists we ask it about its shared object support and if it's
5772 the dlopen-style one we shamelessly guess the compiler and linker flags
5773 for creating shared objects from Perls knowledge. Of course, the user is
5774 warning about what we are doing and informed that he should send us
5775 the guessed flags when they work. [Ralf S. Engelschall]
5777 *) Provide APACI --without-support option to be able to disable the build
5778 and installation of the support tools from the src/support/ area.
5779 Although its useful to have these installed per default we should provide
5780 a way to compile and install without them for backward-compatibility.
5781 [Ralf S. Engelschall]
5783 *) Add of the new APache eXtenSion (apxs) support tool for building and
5784 installing modules into an _already installed_ Apache package through the
5785 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5786 this approach actually doesn't need the Apache source tree. The
5787 (APACI-installed) server package is enough, because this now includes the
5788 Apache C header files (PREFIX/include) and the new APXS tool
5789 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5790 module authors to build their Apache modules _OUTSIDE_ the Apache source
5791 tree while avoiding them to fiddle around with the totally platform
5792 dependend way of compiling DSO files. The tool supports all ranges of
5793 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5794 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5795 on-the-fly generate a minimalistic Makefile and sample module for the
5796 first step to provide both a quick success event and to demonstrate the
5797 APXS mechanism to module authors. [Ralf S. Engelschall]
5799 *) Fix core dumps in use of CONNECT in proxy.
5800 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5802 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5803 so that users have examples of how CustomLog can be used.
5806 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5807 the Apache distribution tree. Until Apache 1.3 there was no real
5808 out-of-the-box batch-capable build and installation procedure for the
5809 complete Apache package. This is now provided by a top-level "configure"
5810 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5811 to provide a GNU Autoconf-style frontend which is capable to both drive
5812 the old src/Configure stuff in batch and additionally installs the
5813 package with a GNU-conforming directory layout. Any options from the old
5814 configuration scheme are available plus a lot of new options for flexibly
5815 customizing Apache. [Ralf S. Engelschall]
5817 *) The floating point ap_snprintf code wasn't threadsafe.
5818 Had to remove the HAVE_CVT macro in order to do threadsafe
5819 calling of the ?cvt() floating point routines. [Dean Gaudet]

5826 *) BUG: Configure was using TCC and CC inconsistently. Make sure
5827 Configure knows which CC we are using. [Jim Jagielski]
5829 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5830 was defined in a parent directory. [Lars Eilebrecht]
5832 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5833 a generic printf-style routine that can call arbitrary output
5834 routines. Use this to replace http_bprintf.c. Add new routines
5835 psprintf(), pvsprintf() which allocate the exact amount of memory
5836 required for a string from a pool. Use psprintf() to clean up
5837 various bits of code which used ap_snprintf()/pstrdup().
5840 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5841 ap_snprintf() has different semantics and formatting codes than
5842 snprintf(). [Dean Gaudet]
5844 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5845 is necessary on at least Solaris where the /etc/rc?.d scripts
5846 are run with these signals ignored, and "SIG_IGN" settings are
5847 maintained across exec().

5875 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5876 therefore not exposed to %2F -> '/' translations and 2) the request
5877 is a proxy request, so we're not dealing with a local resource anyway.
5878 Without this, the proxy would fail to work for any URL's with
5879 %2f in them (occurs quite often in

5894 code) from the already used FTP SIZE command to setup the Content-Length
5895 header if available. [Ralf S. Engelschall] PR#1183
5897 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5898 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5899 name was really too generic, added documentation for this directive to
5900 the mod_proxy.html and corrected the hyperlink to it in the
5901 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5903 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5904 faster [Martin Kraemer]
5906 *) Make Configure die when you give it an unknown command switch.
5909 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5910 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5911 and per default compiled support programs have manual pages - just to
5912 document our stuff a little bit more and to be able to do really
5913 Unix-like installations ;-) [Ralf S. Engelschall]
5915 *) Major cleanups to the Configure script to make it and its generated
5916 Makefiles again readable and maintainable: add SRCDIR option, removed
5917 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5918 generated sections, consequently added Makefile headers with inheritance
5919 information, added subdir movement messages for easier following where
5920 the build process currently stays (more verbose then standard Make, less
5921 verbose than GNU make), same style to comments in the Configure script,
5922 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5924 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5925 from the ZeusBench benchmarking program and can be used to determine the
5926 response performance of an Apache installation. This version is
5927 officially licensed with Zeus Technology, Ltd. See the license agreement
5928 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5929 [Ralf S. Engelschall]
5931 *) API: Various core functions that are definately not part of the API
5932 have been made static, and a few have been marked API_EXPORT. Still
5933 more have been marked CORE_EXPORT and are not intended for general
5934 use by modules. [Doug MacEachern, Dean Gaudet]
5936 *) mod_proxy was not clearing the Proxy-Connection header from
5937 requests; now it does. This did not violate any spec, however
5938 causes poor interactions when you are talking to remote proxies.

5947 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5949 *) Clean up some undocumented behavior of mod_setenvif related to
5950 "merging" two SetEnvIf directives when they match the same header
5951 and regex. Document that mod_setenvif will perform comparisons in
5952 the order they appear in the config file. Optimize mod_setenvif by
5953 doing more work at config time rather than at runtime.
5956 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5957 to allow for modules to overrule them and to reduce redefinition
5958 warnings [Jim Jagielski]
5960 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5963 *) Making the hard-coded cross-module function call mime_find_ct() (from
5964 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5965 checking is really called even for proxy requests except for URLs with
5966 HTTP schemes (because there we can optimize by not running the type
5967 checking hooks due to the fact that the proxy gets the MIME Content-type
5968 from the remote host later). This change cleans up mod_mime by removing
5969 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5970 especially unbundles mod_proxy and mod_mime. This way they both now can
5971 be compiled as shared objects and are no longer tied together.
5972 [Ralf S. Engelschall]
5974 *) util.c cleanup and speedup. [Dean Gaudet]
5976 *) API: Clarification, pstrndup() will always copy n bytes of the source
5977 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5979 *) Mark module command_rec and handler_rec structures const so that they
5980 end up in the read-only data section (and are friendlier to systems
5981 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5983 *) Add check to the "Port" directive to make sure the specified
5984 port is in the appropriate range. [Ben Hyde]
5986 *) Performance improvements to invoke_handler().
5987 [Dmitry Khrustalev <dima@bog.msu.su>]
5989 *) Added support for building shared objects even for library-style modules
5990 (which are built from more than one object file). This now provides the
5991 ability to build mod_proxy as a shared object module. Additionally
5992 modules like mod_example are now also supported for shared object
5993 building because the generated Makefiles now no longer assume there is at
5994 least one statically linked module. [Ralf S. Engelschall]
5996 *) API: Clarify usage of content_type, handler, content_encoding,
5997 content_language and content_languages fields in request_rec. They
5998 must always be lowercased; and the strings pointed to shouldn't
5999 be modified (you must copy them to modify them). Fix a few bugs
6000 related to this. [Dean Gaudet]
6002 *) API: Clarification: except for RAW_ARGS, all command handlers can
6003 treat the char * parameters as permanent, and modifiable. There
6004 is no need to pstrdup() them. Clean up some needless pstrdup().
6007 *) Now mod_so keeps track of which module shared objects with which names
6008 are loaded and thus avoids multiple loading and unloading and irritating
6009 error_log messages. [Ralf S. Engelschall]
6011 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6012 environment variable in the apache core. But that tweaking interferes
6013 with mod_setenv. So don't tweak if the user has specified an explicit
6014 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
6016 *) rputs() did not calculate r->sent_bodyct properly.
6017 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
6019 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
6020 name, or left unset if this value is unavailable. Apache was setting
6021 it to the IP address when unavailable.
6022 [Tony Finch <fanf@demon.net>] PR#1925
6024 *) Various improvements to the configuration and build support for compiling
6025 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6026 OSF1 support with GCC and vendor compilers was added. This way shared
6027 object support is now provided out-of-the-box for FreeBSD, Linux,
6028 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!

6031 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6032 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6033 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6035 *) Fix one more special locking problem for RewriteMap programs in
6036 mod_rewrite: According to the documentation of flock(), "Locks are on
6037 files, not file descriptors. That is, file descriptors duplicated
6038 through dup(2) or fork(2) do not result in multiple instances of a lock,
6039 but rather multiple references to a single lock. If a process holding a
6040 lock on a file forks and the child explicitly unlocks the file, the
6041 parent will lose its lock.". To overcome this we have to make sure the
6042 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6043 the case by opening it in the child_init instead of the module_init API
6044 hook. [Ralf S. Engelschall] PR#1029
6046 *) Change to Location and LocationMatch semantics. LocationMatch no
6047 longer lets a single slash match multiple adjacent slashes in the
6048 URL. This change is for consistency with RewriteRule and
6049 AliasMatch. Multiple slashes have meaning in URLs that they do
6050 not have in (some) filesystems. Location on the other hand can
6051 be considered a shorthand for a more complicated regex, and it
6052 does match multiple slashes with a single slash -- which is
6053 also consistent with the Alias directive.

6056 *) Fix bug with mod_mime_magic causing certain files, including files
6057 of length 0, to result in no response from the server.
6060 *) The Configure script now generates src/include/ap_config.h which
6061 contains the set of defines used when Apache is compiled on a platform.
6062 This file can then be included by external modules before including
6063 any Apache header files in case they are being built separately from
6064 Apache. Along with this change, a couple of minor changes were
6065 made to make Apache's #defines coexist peacefully with any autoconf
6066 defines an external module might have. [Rasmus Lerdorf]
6068 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6069 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6070 chance by the API to initialize its per-server configuration and thus
6071 receives the wrong one from the main server. This is now avoided by
6072 remembering the server together with the config structure while
6073 configuring and later assuming there is no config when we see a
6074 difference between the remembered server and the one calling us.
6075 [Ralf S. Engelschall] PR#1790
6077 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6078 is automatically disabled under configure time when the dbm_xxx functions
6079 are not available. Second, two heavy source code errors in the DBM
6080 support code were fixed. This makes DBM RewriteMap's usable again after
6081 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6083 *) Now all configuration files support Unix-style line-continuation via
6084 the trailing backslash ("\") character. This enables us to write down
6085 complex or just very long directives in a more readable way. The
6086 backslash character has to be really the last character before the
6087 newline and it has not been prefixed by another (escaping) backslash.

6093 *) To deal with modules being compiled and [dynamically] linked
6094 at a different time from the core, the SERVER_VERSION and
6095 SERVER_BUILT symbols have been abstracted through the new
6096 API routines apapi_get_server_version() and apapi_get_server_built().
6099 *) WIN32: Preserve trailing slash in canonical path (and hence
6100 in PATH_INFO). [Paul Sutton, Ben Laurie]
6102 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6103 depending on the rev of Solaris and what mixture of modules
6104 are in use. So it has been disabled, and Solaris is back to
6105 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6106 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6107 up static content only servers. Or it may fail unpredictably.

6110 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6113 *) API: Rewrite of absoluteURI handling, and in particular how
6114 absoluteURIs match vhosts. Unless a request is a proxy request, a
6115 "http://host" url is treated as if a similar "Host:" header had been
6116 supplied. This change was made to support future HTTP/1.x protocols
6117 which may require clients to send absoluteURIs for all requests.
6119 In order to achieve this change subtle changes were made to the API. In a
6120 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6121 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6122 by the core, modules must set it during the post_read_request or
6123 translate_names phase.
6125 Plus changes to the virtualhost test suite for absoluteURI testing.
6127 This fixes several bugs with the proxy proxying requests to vhosts
6128 managed by the same httpd.
6131 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6132 code from mod_rewrite. The vhost matching is now performed by a
6133 globally available function matches_request_vhost(). [Dean Gaudet]
6135 *) Reduce memory usage, and speed up ServerAlias support. As a

6149 *) API: A new source module main/util_uri.c; It contains a routine
6150 parse_uri_components() and friends which breaks a URI into its component
6151 parts. These parts are stored in a uri_components structure called
6152 parsed_uri within each request_rec, and are available to all modules.
6153 Additionally, an unparse routine is supplied which re-assembles the URI
6154 components back to an URI, optionally hiding the username:password@ part
6155 from ftp proxy requests, and other useful routines. Within the structure,
6156 you find on a ready-for-use basis:
6157 scheme; /* scheme ("http"/"ftp"/...) */
6158 hostinfo; /* combined [user[:password]@]host[:port] */
6159 user; /* user name, as in http://user:passwd@host:port/ */
6160 password; /* password, as in http://user:passwd@host:port/ */
6161 hostname; /* hostname from URI (or from Host: header) */
6162 port_str; /* port string (integer representation is in "port") */
6163 path; /* the request path (or "/" if only scheme://host was given) */
6164 query; /* Everything after a '?' in the path, if present */
6165 fragment; /* Trailing "#fragment" string, if present */
6166 This is meant to serve as the platform for *BIG* savings in
6167 code complexity for the proxy module (and maybe the vhost logic).
6170 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6171 ${map:key}) available for all location where a string is created in
6172 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6173 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6174 possible expansions are consequently usable at all string creation
6175 locations. [Ralf S. Engelschall]
6177 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6178 and not 1) and the per-virtual-server merging of directives. Now all
6179 directives except `RewriteEngine' and `RewriteOption' are either
6180 completely overridden (default) or completely inherited (when
6181 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6184 defined but disabled (`RewriteEngine off') in per-server context.

6187 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6188 server to bind to port 0 rather than 80. [Dean Gaudet]
6190 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6191 (like SunOS and FreeBSD) which don't accept the locking of pipes
6192 directly. A new directive RewriteLock is introduced which can be used to
6193 setup a separate locking file which then is used for synchronization.

6208 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6209 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6211 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6212 type but with a special post-processing for the looked-up value: It
6213 parses it into alternatives according to `|' chars and then only one
6214 particular alternative is chosen randomly (this is an essential
6215 functionality needed for balancing between backend-servers when using
6216 Apache as a Reverse Proxy. The looked up value here is a list of
6217 servers). Second, `int' with the built-in maps named `tolower' and
6218 `toupper' which can be used to map URL parts to a fixed case (this is an
6219 essential feature to fix the case of server names when doing mass
6220 virtual-hosting with the help of mod_rewrite instead of using
6221 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6222 Jay Soffian <jay@cimedia.com>] PR#1631
6224 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6225 This directive lets Apache adjust the URL in Location-headers on HTTP
6226 redirect responses sent by the remote server. This way the virtually
6227 mapped area is no longer left on redirects and thus by-passed which is
6228 especially essential when running Apache as a reverse proxy.

6384 the OS-abstraction files. [Ken Coar]
6386 *) Fix a bug where r->hostname didn't have the :port stripped
6387 from it. [Dean Gaudet]
6389 *) Tweaked the headers_out table size, and the subprocess_env
6390 table size guess in rename_original_environment(). Added
6391 MAKE_TABLE_PROFILE which can help discover make_table()
6392 calls that use too small an initial guess, see alloc.c.
6395 *) Options and AllowOverride weren't properly merging in the main
6396 server setting inside vhosts (only an issue when you have no
6397 <Directory> or other section containing an Options that affects
6398 a request). Options +foo or -foo in the main_server wouldn't
6399 affect the main_server's lookup defaults. [Dean Gaudet]
6401 *) Variable 'cwd' was being used pointlessly before being set.
6404 *) r->allowed handling cleaned up in the standard modules.
6407 *) Some case-sensitivity issues cleaned up to be consistent with
6408 RFC2068. [Dean Gaudet]
6410 *) SIGURG doesn't exist everywhere.
6411 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
6413 *) mod_unique_id was erroneously generating a second unique id when
6414 an internal redirect occured. Such redirects occur, for example,
6415 when processing a DirectoryIndex match. [Dean Gaudet]
6417 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6418 of the key and value. But in many cases this is not required
6419 because the key/value is a constant, or the value has been built
6420 by pstrcat() or other similar means. New routines table_addn,
6421 table_mergen, and table_setn have been added to the API, these
6422 routines do not pstrdup() their arguments. The core code and
6423 standard modules were changed to take advantage of these routines.
6424 The resulting server is up to 20% faster in some situations.
6426 Note that it is easy to get code subtly wrong if you pass a key/value
6427 which is in a pool other than the pool of the table. The only
6428 safe thing to do is to pass key/values which are in the pool of
6429 the table, or in one of the ancestors of the pool of the table.
6430 i.e. if the table is part of a subrequest, a value from the main
6431 request's pool is OK since the subrequest pool is a sub_pool of the
6432 main request's pool (and therefore has a lifespan at most as long as
6433 the main pool). There is debugging code which can detect improper
6434 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6435 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6437 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6438 which don't exist on disk more gracefully; handles vhosts properly.
6439 Update documentation to reflect the code -- if there's no
6440 MimeMagicFile directive then the module is not enabled.
6443 *) PORT: Some older *nix dialects cannot automatically start scripts
6444 which begin with a #! interpreter line (the shell starts the scripts
6445 appropriately on these platforms). Apache now supports starting of
6446 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.
6447 [Martin Kraemer, with code from peter@zeus.dialix.oz.au (Peter Wemm)
6450 *) API: "typedef array_header table" removed from alloc.h, folks should
6451 have been writing to use table as if it were an opaque type, but even
6452 some standard modules got this wrong. By changing the definition
6453 to "typedef struct table table" module authors will receive compile
6454 time warnings that they're doing the wrong thing. This change
6455 facilitates future changes with more sophisticated table
6456 structures. Specifically, module authors should be using table_elts()
6457 to get access to an array_header * for the table. [Dean Gaudet]
6459 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6460 library routines. [Ken Coar, Rasmus Lerdorf]
6462 *) WIN32: mod_speling is now available on the Win32 platform.
6465 *) For clarity the following compile time definition was changed:
6467 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6469 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6470 and not be a general notice that the OS has mmap(). Now the
6471 HAVE_MMAP/SHMGET #defines strictly are informational that the
6472 OS has that method of shared memory; the type to use for
6473 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6474 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6475 determine if shared memory is available and allows Apache
6476 to determine the best method to use for the scoreboard.
6479 *) PORT: UnixWare 2.1.2 SMP appears to require USE_FCNTL_SERIALIZED_ACCEPT,
6480 as do various earlier versions. It should be safe on all versions.

6482 the slack code. A few other cleanups for Unixware.

6505 The choice of flock vs. fcntl was made based on timings which showed that
6506 even on non-NFS, non-exported filesystems fcntl() was an order of
6507 magnitude slower. It also uses SINGLE_LISTEN_UNSERIALIZED_ACCEPT so
6508 that single socket users will see no difference. [Dean Gaudet] PR#467

6518 necessary because SIGPROF is lost across a fork(). [Dean Gaudet]

6534 *) The src/main/*.h header files have had #ifndef wrappers added to
6535 insulate them against duplicate calls if they get included through

6539 *) The libap routines now have a header file for their prototypes,
6540 src/ap/ap.h, to ease their use in non-httpd applications. [Ken Coar]
6542 *) mod_autoindex with a plaintext header file would emit the <PRE>

6568 *) For maximum portability, the environment passed to CGIs should
6569 only contain variables whose names match the regex

6571 underscores over any character outside the regex. This
6572 affects HTTP_* variables, in a way that should be backward
6573 compatible for all the standard headers; and affects variables

6670 bytes have to be supplied to bwrite() before it will consider
6671 doing a writev() to assemble multiple buffers in one system
6672 call. This is critical for modules such as mod_include,
6673 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller

6675 setting up writev(), and in many cases extra effort building

6817 is the same for both per-server and per-directory context with only a
6818 minimum difference (the prefix stripping in per-dir context). As a
6819 side-effect some subtle restrictions and two recently discovered problems
6820 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory

6914 Document this a bit more in src/PORTING. [Dean Gaudet] PR#467
6916 *) Ensure that one copy of config warnings makes it to the
6917 error_log. [Dean Gaudet]

6946 __NetBSD__. Workaround by defining NETBSD.
6947 [Chris Craft <ccraft@cncc.cc.co.us>] PR#977
6949 *) PORT: UnixWare 2.x requires -lgen for syslog.
6950 [Hans Snijder <hs@meganet.nl>] PR#1249
6952 *) PORT: ULTRIX appears to not have syslog.

6958 *) PORT: All SVR4 systems now use NET_SIZE_T = size_t, and
6959 use USE_SHMGET_SCOREBOARD.
6962 *) Various improvements in detecting config file errors (missing closing
6963 directives for <Directory>, <Files> etc. blocks, prohibiting global
6964 server settings in <VirtualHost> blocks, flagging unhandled multiple
6965 arguments to <Directory>, <Files> etc.)
6968 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
6969 variable to provide this one to suexec'd CGIs, too.
6970 [M.D.Parker <mdpc@netcom.com>] PR#1284
6972 *) New support tool: src/support/split-logfile, a sample Perl script which
6973 splits up a combined access log into separate files based on the
6974 name of the virtual host (listed first in the log records by "%v").
6977 Changes with Apache 1.3b2 (there is no 1.3b1)
6979 *) TestCompile was not passing $LIBS [Dean Gaudet]
6981 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6984 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6985 rudimentary memory debugger which can be used on live servers with
6986 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6987 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6988 and free() for each object. This is far more expensive and should
6989 only be used for testing with tools such as Electric Fence and
6990 Purify. See main/alloc.c for more details. [Dean Gaudet]
6992 *) Configure uses a sh trap and didn't set its exitcode properly.
6993 [Dean Gaudet] PR#1159
6995 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6996 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6997 From a given ip:port, regardless what the Host: header is, you can
6998 only reach the vhosts defined on that ip:port. The precedence of
6999 vhosts was reversed to match other precedences in the config --
7000 the earlier vhosts override the later vhosts. All vhost matching was
7001 moved into http_vhost.[ch]. [Dean Gaudet]
7003 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7004 be used for whatever reason is appropriate (i.e. format() warnings
7005 for printf style functions). Both are enabled only with
7006 gcc >= 2.7.x (so that we have fewer support issues with older
7007 versions). [Dean Gaudet]
7009 *) Fix support for Proxy Authentication (we were testing the response
7010 status too early). [Marc Slemko]
7012 *) CoreDumpDirectory directive directs where the core file is
7013 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7014 received. [Marc Slemko, Dean Gaudet]
7016 *) PORT: Support for Atari MINT.
7017 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7019 *) When booting, apache will now detach itself from stdin, stdout,
7020 and stderr. stderr will not be detached until after the config
7021 files have been read so you will be able to see initial error
7022 messages. After that all errors are logged in the error_log.
7023 This makes it more convenient to start apache via rsh, ssh,
7024 or crontabs. [Dean Gaudet] PR#523
7026 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7027 Also removed the auto-generated link to www.apache.org that was the
7028 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7030 *) send_fb would not detect aborted connections in some situations.
7033 *) mod_include would use uninitialized data when parsing certain
7034 expressions involving && and ||. [Brian Slesinsky] PR#1139
7036 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7038 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7040 *) mod_autoindex improperly counted &escapes; as more than one
7041 character in the description. It also improperly truncated
7042 descriptions that were exactly the maximum length.
7045 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7046 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7049 *) mod_include now uses symbolic names to check for request success
7050 and return HTTP errors, and correctly handles all types of
7051 redirections (previously it only did temporary redirect correctly).
7052 [Ken Coar, Roy Fielding]
7054 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7055 r->filename. Since those two are meant to be in sync with each other
7056 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7058 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7059 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7061 *) Inetd mode (which is buggy) uses timeouts without having setup the
7062 jmpbuffer. [Dean Gaudet] PR#1064
7064 *) Work around problem under Linux where a child will start looping
7065 reporting a select error over and over.
7066 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7068 *) Fixed error in proxy_util.c when looping through multiple host IP
7069 addresses. [Lars Eilebrecht] PR#974
7071 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7072 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7073 bytes before writing, but it will never split a log entry across a
7074 buffer boundary. [Dean Gaudet]
7076 *) API: the short_score record has been split into two pieces, one which
7077 the parent writes on, and one which the child writes on. As part of
7078 this change the get_scoreboard_info() function was removed, and
7079 scoreboard_image was exported. This change fixes a race condition
7080 in file based scoreboard systems, and speeds up changes involving the
7081 scoreboard in earlier 1.3 development. [Dean Gaudet]
7083 *) API: New register_other_child() API (see http_main.h) which allows
7084 modules to register children with the parent for maintenance. It
7085 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7087 *) API: New piped_log API (see http_log.h) which implements piped logs,
7088 and will use register_other_child to implement reliable piped logs
7089 when it is available. The reliable piped logs part can be disabled
7090 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7091 logs is only available on Unix. [Dean Gaudet]
7093 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7094 meets_conditions(). This allows conditional HTTP selection to be
7095 handled separately from the storing of the header fields, and provides
7096 the ability for CGIs to set their own ETags for conditional checking.
7097 [Ken Coar, Roy Fielding] PR#895
7099 *) Changes to mod_log_config to allow naming of format strings.
7100 Format nicknames are defined with "LogFormat fmt nickname", and can
7101 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7104 *) New module, "mod_speling", which can help find files even when
7105 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7107 *) API: New function child_terminate() triggers the child process to
7108 exit, while allowing the child finish what it needs to for the
7109 current request first.
7110 [Doug MacEachern, Alexei Kosut]
7112 *) Windows now defaults to using full status reports with mod_status.
7113 [Alexei Kosut] PR #1094
7115 *) *Really* disable all mod_rewrite operations if the engine is off.
7116 Some things (like RewriteMaps) were checked/performed even if they
7117 weren't supposed to be. [Ken Coar] PR #991
7119 *) Implement a new timer scheme which eliminates the need to call alarm() all
7120 the time. Instead a counter in the scoreboard for each child is used to
7121 show when the child has made forward progress. The parent samples this
7122 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7123 progress has been made in the timeout period. This reduces the static
7124 request best-case syscall count to 22 from 29. This scheme is only
7125 used by systems with memory-based scoreboards. [Dean Gaudet]
7127 *) The proxy now properly handles CONNECT requests which are sent
7128 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7130 *) A script called apachectl has been added to the support
7131 directory. This script allows you to do things such as
7132 "apachectl start" and "apachectl restart" from the command
7135 *) Modules and core routines are now put into libraries, which
7136 simplifies the link line tremendously (among other advantages).
7139 *) Some of the MD5 names defined in Apache have been renamed to have
7140 an `ap_' prefix to avoid conflicts with routines supplied by
7141 external libraries. [Ken Coar]
7143 *) Removal of mod_auth_msql.c from the distribution. There are many
7144 other options for databases today. Rather than offer one option,
7145 offer none at this time. mod_auth_msql and other SQL database
7146 authentication modules can be found at the Apache Module Registry.
7147 http://modules.apache.org/ It would be nice to offer a generic
7148 mod_auth_sql option in the near future.
7150 *) PORT: BeOS support added [Alexei Kosut]
7152 *) Configure no longer accepts the -make option, since it creates
7153 Makefile on the fly based on Makefile.tmpl and Configuration.
7155 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7156 of forcibly killing off all its processes and exiting without
7157 cleaning up. [Alexei Kosut]
7159 *) API: A new field in the request_rec, r->mtime, has been added to
7160 avoid gratuitous parsing of date strings. It is intended to hold
7161 the last-modified date of the resource (if applicable). An
7162 update_mtime() routine has also been added to advance it if
7163 appropriate. [Roy Fielding, Ken Coar]
7165 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7166 deny access to the directory with a HTTP_FORBIDDEN. The previous
7167 behavior was to ignore the htaccess file if it could not be read.
7168 This change may make some setups with unreadable htaccess files
7169 stop working. [Marc Slemko] PR#817
7171 *) Add aplog_error() providing a mechanism to define levels of
7172 verbosity to the server error logging. This addition also provides
7173 the ability to log errors using syslogd. Error logging is configurable
7174 on a per-server basis using the LogLevel directive. Conversion
7175 of log_*() in progress. [Randy Terbush]
7177 *) Further enhance aplog_error() to not log filename, line number, and
7178 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7180 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7181 converted to long ones. Backslashes are converted to forward
7182 slashes. Case is converted to lower. Parts of URLs that do not
7183 correspond to files are left completely alone. [Ben Laurie]
7185 *) PORT: 2 new OSs added to the list of ports:
7186 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7187 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7189 *) Add the server version (SERVER_VERSION macro) to the "server
7190 configured and running" entry in the error_log. Also build an
7191 object file at link-time that contains the current time
7192 (SERVER_BUILT global const char[]), and include that in the
7195 *) Set r->headers_out when sending responses from the proxy.
7196 This fixes things such as the logging of headers sent from
7197 the proxy. [Marc Slemko] PR#659
7199 *) support/httpd_monitor is no longer distributed because the
7200 scoreboard should not be file based if at all possible. Use
7201 mod_status to see current server snapshot.
7203 *) (set_file_slot): New function, allowing auth directives to be
7204 independent of the server root, so the server documents can be
7205 moved to a different directory or machine more easily.
7206 [David J. MacKenzie]
7208 *) If no TransferLog is given explicitly, decline
7209 to log. This supports coexistence with other logging modules,
7210 such as the custom one that UUNET uses. [David J. MacKenzie]
7212 *) Check for titles in server-parsed HTML files.
7213 Ignore leading newlines and returns in titles. The old behavior
7214 of replacing a newline after <title> with a space causes the
7215 title to be misaligned in the listing. [David J. MacKenzie]
7217 *) Change mod_cern_meta to be configurable on a per-directory basis.
7218 [David J. MacKenzie]
7220 *) Add 'Include' directive to allow inclusion of configuration
7221 files within configuration files. [Randy Terbush]
7223 *) Proxy errors on connect() are logged to the error_log (nothing
7224 new); now they include the IP address and port that failed
7225 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7227 *) Various architectures now define USE_MMAP_FILES which causes
7228 the server to use mmap() for static files. There are two
7229 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7230 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7231 number of bytes written in one cycle from a single mmap()d object,
7232 default 32768). [Dean Gaudet]
7234 *) API: Added post_read_request API phase which is run right after reading
7235 the request from a client, or right after an internal redirect. It is
7236 useful for modules setting environment variables that depend only on
7237 the headers/contents of the request. It does not run during subrequests
7238 because subrequests inherit pretty much everything from the main
7239 request. [Dean Gaudet]
7241 *) Added mod_unique_id which is used to generate a unique identifier for
7242 each hit, available in the environment variable UNIQUE_ID.
7245 *) init_modules is now called after the error logs have been opened. This
7246 allows modules to emit information messages into the error logs.
7249 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7250 information for case where proxy module is not available. [Marc Slemko]
7252 *) PORT: Apache has need for mutexes to serialize its children around
7253 accept. In prior versions either fcntl file locking or flock file
7254 locking were used. The method is chosen by the definition of
7255 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7256 and FLOCK for flock(). New options have been added:
7257 - SYSVSEM to use System V style semaphores
7258 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7259 - USLOCK to use IRIX uslock
7260 Based on timing various techniques, the following changes were made
7262 - Linux 2.x uses flock instead of fcntl
7263 - Solaris 2.x uses pthreads
7264 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7265 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7266 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7267 Martijn Koster <m.koster@pobox.com>]
7269 *) PORT: The semantics of accept/select make it very desirable to use
7270 mutexes to serialize accept when multiple Listens are in use. But
7271 in the case where only a single socket is open it is sometimes
7272 redundant to serialize accept(). Not all unixes do a good job with
7273 potentially dozens of children blocked on accept() on the same
7274 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7275 the server will avoid serialization when listening on only one socket,
7276 and use serialization when listening on multiple sockets.
7277 [Dean Gaudet] PR#467
7279 *) Configure changes: TestLib replaced by TestCompile, which has
7280 some additional capability (such as doing a sanity check of
7281 the compiler and flags selected); the version of Solaris is now
7282 available via the #define value of SOLARIS2; IRIX n32bit libs
7283 now supported and selectable by new Configuration Rule: IRIXN32;
7284 We no longer default to -O2 optimization. [Jim Jagielski]
7286 *) Updated Configure: Configuration now uses AddModule to specify
7287 module source or binary file location, relative to src directory.
7288 Modules can be dropped into modules/extra, or in their own
7289 directory, and modules can come with a Makefile or Configure can
7290 create one. Modules can add compiler or library information to
7291 generated Makefiles. [Paul Sutton]
7293 *) Source core re-organisation: distributed modules are now in
7294 modules/standard. All other source code is in main. OS-specific
7295 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7297 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7300 *) Fix another long-standing bug in sub_req_lookup_file where it would
7301 happily skip past access checks on subdirectories looked up with
7302 relative paths. (It's used by mod_dir, mod_negotiation,
7303 and mod_include.) [Dean Gaudet]
7305 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7306 N is the number of <Directory> sections, and M is the number of
7307 components in the filename of an object.
7309 To achieve this optimization the following config changes were made:
7310 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7311 <Files>s, and <Location>s now treat a slash as a special
7312 character. For example "/home/*/public_html" previously would
7313 match "/home/a/andrew/public_html", now it only matches things
7314 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7315 - It's possible now to use [] wildcarding in <Directory>, <Files>
7317 - Regex <Directory>s are applied after all non-regex <Directory>s.
7321 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7322 and corrupted paths. [Dean Gaudet]
7324 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7325 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7326 be accessed now via backreferences $1..$9 in RewriteConds test-against
7327 strings in addition to RewriteRules subst string. Second the grouped
7328 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7329 via backreferences %1..%9 both in following RewriteCond test-against
7330 strings and RewriteRules subst string. This provides maximum flexibility
7331 through the use of backreferences.
7332 Additionally the rewriting engine was cleaned up by putting common
7333 code to the new expand_backrefs_inbuffer() function.
7334 [Ralf S. Engelschall]
7336 *) When merging the main server's <Directory> and <Location> sections into
7337 a vhost, put the main server's first and the vhost's second. Otherwise
7338 the vhost can't override the main server. [Dean Gaudet] PR#717
7340 *) The <Directory> code would merge and re-merge the same section after
7341 a match was found, possibly causing problems with some modules.
7344 *) ip-based vhosts are stored and queried using a hashing function, which
7345 has been shown to improve performance on servers with many ip-vhosts.
7346 Some other changes had to be made to accommodate this:
7347 - the * address for vhosts now behaves like _default_
7348 - the matching process now is:
7349 - match an ip-vhost directly via hash (possibly matches main
7351 - if that fails, just pretend it matched the main server
7352 - if so far only the main server has been matched, perform
7353 name-based lookups (ServerName, ServerAlias, ServerPath)
7354 *only on name-based vhosts*
7355 - if they fail, look for _default_ vhosts
7356 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7358 *) dbmmanage overhaul:
7359 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7360 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7361 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7362 - provide better seed for rand
7363 - prompt for password as per getpass(3) (turn off echo, read from
7365 - use "newstyle" crypt based on $Config{osname} ($^O)
7366 - will not add a user if already in database, use new `update' command
7368 - added `check' command to check a users' password
7369 - added `import' command to convert existing password text-files or
7370 dbm files exported with `view'
7371 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7374 *) Added psocket() which is a pool form of socket(), various places within
7375 the proxy weren't properly blocking alarms while registering the cleanup
7376 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7377 was a bug where the client socket was being close()d twice due a still
7378 registered cleanup. [Dean Gaudet]
7380 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7383 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7384 [Jason Venner <jason@idiom.com>] PR#667
7386 *) Enable ``=""'' for RewriteCond directives to match against
7387 the empty string. This is the preferred way instead of ``^$''.
7388 [Ralf S. Engelschall]
7390 *) Fixed an infinite loop in mod_imap for references above the server root
7391 [Dean Gaudet] PR#748
7393 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7394 SendBufferSize, so that the TCP window can be set appropriately
7395 for LFNs. [Phillip A. Prindeville]
7397 *) mod_browser has been replaced by the more general mod_setenvif
7398 (courtesy of Paul Sutton). BrowserMatch* directives are still
7399 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7400 UnSetEnvIfZero directives. [Ken Coar]
7402 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7403 order for remote_host to be set (for logging, or for the env var
7404 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7407 *) mod_access overhaul:
7408 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7409 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7410 - Critical path was sped up by pre-computing a few things at config time.
7411 - The undocumented syntax "allow user-agents" was removed,
7412 the replacement is "allow from env=foobar" combined with mod_browser.
7413 - When used with hostnames it now forces a double-reverse lookup
7414 no matter what the directory settings are. This double-reverse
7415 doesn't affect any of the other routines that use the remote
7416 hostname. In particular it's still passed to CGIs and the log
7417 without the double-reverse check. Related PR#860.
7420 *) When a large bwrite() occurs (larger than the internal buffer size),
7421 while there is already something in the buffer, apache will combine
7422 the large write and the buffer into a single writev(). (This is
7423 in anticipation of using mmap() for reading files.)
7426 *) In obscure cases where a partial socket write occurred while chunking,
7427 Apache would omit the chunk header/footer on the next block. Cleaned
7428 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7429 a bug where a long pause in DNS lookups could cause the last packet
7430 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7432 *) API: Added child_exit function to module structure. This is called
7433 once per "heavy-weight process" just before a server child exit()'s
7434 e.g. when max_requests_per_child is reached, etc.
7435 [Doug MacEachern, Dean Gaudet]
7437 *) mod_include cleanup showed that handle_else was being used to handle
7438 endif. It didn't cause problems, but it was cleaned up too.
7441 *) mod_cern_meta would attempt to find meta files for the directory itself
7442 in some cases, but not in others. It now avoids it in all cases.
7445 *) mod_mime_magic would core dump if there was a decompression error.
7446 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7448 *) PORT: some variants of DGUX require -lsocket -lnsl
7449 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7451 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7452 by the various fields (name, size, et cetera), either in ascending
7453 or descending order. Just click on the column header. [Ken Coar]
7455 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7456 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7457 the relatively safe direction. [Dean Gaudet] PR#344
7459 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7460 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7462 *) child_main avoids an unneeded call to select() when there is only one
7463 listening socket. [Dean Gaudet]
7465 *) In the event that the server is starved for idle servers it will
7466 spawn 1, then 2, then 4, ..., then 32 servers each second,
7467 doubling each second. It'll also give a warning in the errorlog
7468 since the most common reason for this is a poor StartServers
7469 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7470 the maximum. [Dean Gaudet]
7472 *) Apache now provides an effectively unbuffered connection for
7473 CGI scripts. This means that data will be sent to the client
7474 as soon as the CGI pauses or stops output; previously, Apache would
7475 buffer the output up to a fixed buffer size before sending, which
7476 could result in the user viewing an empty page until the CGI finished
7477 or output a complete buffer. It is no longer necessary to use an
7478 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7479 in a language that by default does buffering (e.g. perl) this
7480 shouldn't have a detrimental effect on performance.
7482 "nph-" CGIs, which formerly provided a direct socket to the client
7483 without any server post-processing, were not fully compatible with
7484 HTTP/1.1 or SSL support. As such they would have had to implement
7485 the transport details, such as encryption or chunking, in order
7486 to work properly in certain situations. Now, the only difference
7487 between nph and non-nph scripts is "non-parsed headers".
7488 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7490 *) If a BUFF is switched from buffered to unbuffered reading the first
7491 bread() will return whatever remained in the buffer prior to the
7492 switch. [Dean Gaudet]
7494 Changes with Apache 1.3a1
7496 *) Added another Configure helper script: TestLib. It determines
7497 if a specified library exists. [Jim Jagielski]
7499 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7500 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7503 *) PORT: Some architectures use size_t for various lengths in network
7504 functions such as accept(), and getsockname(). The definition
7505 NET_SIZE_T is used to control this. [Dean Gaudet]
7507 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7508 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7509 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7511 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7512 [Igor N Kovalenko <infoh@mail.wplus.net>]
7514 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7515 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7516 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7517 [Dean Gaudet] related PR#875
7519 *) API: Correct child_init() slot declaration from int to void, to
7520 match the init() declaration. Update mod_example to use the new
7523 *) added transport handle slot (t_handle) to the BUFF structure
7526 *) get_client_block() returns wrong length if policy is
7527 REQUEST_CHUNKED_DECHUNK.

7534 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
7535 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
7537 *) AddModuleInfo directive for mod_info which allows you to annotate
7538 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7540 *) Added NoProxy directive to avoid using ProxyRemote for selected
7541 addresses. Added ProxyDomain directive to cause unqualified
7542 names to be qualified by redirection.
7543 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7545 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7546 header to the remote host in the proxy. [Sameer Parekh and
7549 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7550 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7551 URLs, fixed rewritelog(), fixed forced response code handling on
7552 redirects from within .htaccess files, disabled pipe locking under
7553 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7554 no substitution, bugfixed situations where HostnameLookups is off, made
7555 mod_rewrite more thread-safe for NT port and fixed problem when creating
7556 an empty query string via "xxx?".
7557 This update also removes the copyright of Ralf S. Engelschall,
7558 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7559 exclusively copyrighted by the Apache Group now. This happened because
7560 the author now has gifted mod_rewrite exclusively to the Apache Group and
7561 no longer maintains an external version.
7562 [Ralf S. Engelschall]
7564 *) API: Added child_init function to module structure. This is called
7565 once per "heavy-weight process" before any requests are handled.
7566 See http_config.h for more details. [Dean Gaudet]
7568 *) Anonymous_LogEmail was logging on each subrequest.
7569 [Dean Gaudet] PR#421, 868
7571 *) API: Added is_initial_req() which tests if the request being
7572 processed is the initial request, or a subrequest.
7575 *) Extended SSI (mod_include) now handles additional relops for
7576 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7578 *) Configure fixed to correctly propagate user-selected options and
7579 settings (such as CC and OPTIM) to Makefiles other than
7580 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7582 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7583 directory indices to start with the contents of the HeaderName file
7584 if there is one. If there isn't one, the behaviour is unchanged.
7585 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7587 *) WIN32: Modules can now be dynamically loaded DLLs using the
7588 LoadModule/LoadFile directives. Note that module DLLs must be
7589 compiled with the multithreaded DLL version of the runtime library.
7590 [Alexei Kosut and Ben Laurie]
7592 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7593 This allows the admin to completely remove automatic indexing
7594 from the server, while still supporting the basic functions of
7595 trailing-slash redirects and DirectoryIndex files. Note that if
7596 you're carrying over an old Configuration file and you use directory
7597 indexing then you'll want to add:
7599 Module autoindex_module mod_autoindex.o
7601 before mod_dir in your Configuration. [Dean Gaudet]
7603 *) popendir/pclosedir created to properly protect directory scanning.
7604 [Dean Gaudet] PR#525
7606 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7607 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7608 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7611 *) The AccessFileName directive can now take more than one filename.
7612 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7614 *) The new mod_mime_magic can be used to "magically" determine the type
7615 of a file if the extension is unknown. Based on the unix file(1)
7616 command. [Ian Kluft <ikluft@cisco.com>]
7618 *) We now determine and display the time spent processing a
7619 request if desired. [Jim Jagielski]
7621 *) mod_status: PID field of "dead" child slots no longer displays
7622 main httpd process's PID. [Jim Jagielski]
7624 *) Makefile.nt added - to build all the bits from the command line:
7625 nmake -f Makefile.nt
7626 Doesn't yet work properly. [Ben Laurie]
7628 *) Default text of 404 error is now "Not Found" rather than the
7629 potentially misleading "File Not Found". [Ken Coar]
7631 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7632 for the net if we require people that actually need this data to
7633 enable it. [Linus Torvalds]
7635 *) directory_walk() is an expensive function, keep a little more state to
7636 avoid needless string counting. Add two new functions make_dirstr_parent
7637 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7638 The new functions are a little less general than make_dirstr, but
7639 work more efficiently (less memory, less string counting).
7642 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7643 to LDFLAGS) to avoid complications with lex rules in make files.
7644 [Dean Gaudet] PR#372
7646 *) run_method optimized to avoid needless scanning over NULLs in the
7647 module list. [Dean Gaudet]
7649 *) Revamp of (unix) scoreboard management code such that it avoids
7650 unnecessary traversals of the scoreboard on each hit. This is
7651 particularly important for high volume sites with a large
7652 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7653 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7654 httpd.h. [Dean Gaudet]
7656 *) In configurations using multiple Listen statements it was possible for
7657 busy sockets to starve other sockets of service. [Dean Gaudet]
7659 *) Added hook so standalone_main can be replaced at compile time
7660 (define STANDALONE_MAIN)
7663 *) Lowest-level read/write functions in buff.c will be replaced with
7664 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7665 compile time. The default sfio discipline will behave as apache
7666 would without sfio compiled in.
7669 *) Enhance UserDir directive (mod_userdir) to accept a list of
7670 usernames for the 'disable' keyword, and add 'enable user...' to
7671 selectively *en*able userdirs if they're globally disabled.
7674 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7675 will work with Netscape dbm files. (dbmmanage will probably not
7676 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7678 *) Add a ListenBacklog directive to control the backlog parameter
7679 passed to listen(). Also change the default to 511 from 512.
7682 *) API: A new handler response DONE which informs apache that the
7683 request has been handled and it can finish off quickly, similar to
7684 how it handles errors. [Rob Hartill]
7686 *) Turn off chunked encoding after sending terminating chunk/footer
7687 so that we can't do it twice by accident. [Roy Fielding]
7689 *) mod_expire also issues Cache-Control: max-age headers.
7692 *) API: Added kill_only_once option for free_proc_chain so that it won't
7693 aggressively try to kill off specific children. For fastcgi.
7694 [Stanley Gambarin <gambarin@OpenMarket.com>]
7696 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7698 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7699 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7700 attributes in the FancyIndexing IMG tags. [Ken Coar]
7702 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7704 *) PORT: Added Windows NT support
7705 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7707 Changes with Apache 1.2.6
7709 *) mod_include when using XBitHack Full would send ETags in addition to
7710 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7711 [Dean Gaudet] PR#1133
7713 *) SECURITY: When a client connects to a particular port/addr, and
7714 gives a Host: header ensure that the virtual host requested can
7715 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7717 *) Support virtual hosts with wildcard port and/or multiple ports
7718 properly. [Ed Korthof <ed@organic.com>]
7720 *) Fixed some case-sensitivity issues according to RFC2068.
7723 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7724 and mod_include.c. [Dean Gaudet]
7726 *) Variable 'cwd' was being used pointlessly before being set.
7729 *) SIGURG doesn't exist on all platforms.
7730 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7732 *) When an error occurs during a POST, or other operation with a
7733 request body, the body has to be read from the net before allowing
7734 a keepalive session to continue. [Roy Fielding] PR#1399
7736 *) When an error occurs in fcntl() locking suggest the user look up
7737 the docs for LockFile. [Dean Gaudet]
7739 *) table_set() and table_unset() did not deal correctly with
7740 multiple occurrences of the same key. [Stephen Scheck
7741 <sscheck@infonex.net>, Ben Laurie] PR#1604
7743 *) send_fd_length() did not calculate total_bytes_sent properly in error
7744 cases. [Ben Reser <breser@regnow.com>] PR#1366
7746 *) r->connection->user was allocated in the wrong pool causing corruption
7747 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7749 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7750 Also removed the auto-generated link to www.apache.org that was the
7751 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7753 *) Multiple "close" tokens may have been set in the "Connection"
7754 header, not an error, but a waste.
7755 [Ronald.Tschalaer@psi.ch] PR#1683
7757 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7758 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7760 *) It appears the "257th byte" bug (see
7761 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7762 at the 256th byte as well. Fixed. [Dean Gaudet]
7764 *) mod_rewrite would not handle %3f properly in some situations.
7767 *) Apache could generate improperly chunked HTTP/1.1 responses when
7768 the bputc() or rputc() functions were used by modules (such as
7769 mod_include). [Dean Gaudet]
7771 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7772 some ports. [Ralf Engelschall]
7774 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7776 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7778 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7780 Changes with Apache 1.2.5
7782 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7783 only an issue on systems without a MAXDNAME define or where
7784 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7786 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7789 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7790 directory listings. [Marc Slemko]
7792 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7795 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7796 is used to read various types of files such as htaccess and
7797 htpasswd files. [Marc Slemko]
7799 *) SECURITY: Ensure that the buffer returned by ht_time is always
7800 properly null terminated. [Marc Slemko]
7802 *) SECURITY: General mod_include cleanup, including fixing several
7803 possible buffer overflows and a possible infinite loop. This cleanup
7804 was done against 1.3 code and then backported to 1.2, the result
7805 is a large difference (due to indentation cleanup in 1.3 code).
7806 Users interested in seeing a smaller set of relevant differences
7807 should consider comparing against src/modules/standard/mod_include.c
7808 from the 1.3b3 release. Non-indentation changes to mod_include
7809 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7811 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7812 including fixing a possible buffer overflow. This cleanup also
7813 was done with 1.3 code as a basis, see the the previous note
7814 about mod_include. [Dean Gaudet]
7816 *) SECURITY: If a htaccess file can not be read due to bad
7817 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7818 The previous behavior was to ignore the htaccess file if it could not
7819 be read. This change may make some setups with unreadable
7820 htaccess files stop working. PR#817 [Marc Slemko]
7822 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7823 Make it O(n). This inefficiency could be used to mount a denial
7824 of service attack against the Apache server. Thanks to
7825 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
7828 *) mod_include used uninitialized data for some uses of && and ||.

7834 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7836 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7837 r->filename. Since those two are meant to be in sync with each other
7838 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7840 *) mod_include did not properly handle all possible redirects from sub-

7843 *) Inetd mode (which is buggy) uses timeouts without having setup the
7844 jmpbuffer. [Dean Gaudet] PR#1064
7846 *) Work around problem under Linux where a child will start looping
7847 reporting a select error over and over.
7848 [Rick Franchuk <rickf@transpect.net>] PR#1107
7850 Changes with Apache 1.2.4
7852 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7853 always making requests with the full-URI instead of just the URI path.
7854 [Marc Slemko, Roy Fielding]
7856 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7857 on this platform. [Marc Slemko]
7859 Changes with Apache 1.2.3
7861 *) The request to a remote proxy was mangled if it was generated as the
7862 result of a ProxyPass directive. URL schemes other than http:// were not
7863 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7864 PR#812 [Lars Eilebrecht]
7866 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7867 information for case where proxy module is not available. [Marc Slemko]
7869 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7870 do for errors and cached responses. [Roy Fielding]
7872 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7874 Changes with Apache 1.2.2 [not released]
7876 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7877 happily skip past access checks on subdirectories looked up with relative
7878 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7881 *) Add lockfile name to error message printed out when
7882 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7885 *) Enhanced the chunking and error handling inside the buffer functions.
7886 [Dean Gaudet, Roy Fielding]
7888 *) When merging the main server's <Directory> and <Location> sections into
7889 a vhost, put the main server's first and the vhost's second. Otherwise
7890 the vhost can't override the main server. [Dean Gaudet] PR#717
7892 *) The <Directory> code would merge and re-merge the same section after
7893 a match was found, possibly causing problems with some modules.
7896 *) Fixed an infinite loop in mod_imap for references above the server root.
7897 [Dean Gaudet] PR#748
7899 *) mod_include cleanup showed that handle_else was being used to handle
7900 endif. It didn't cause problems, but it was cleaned up too.
7903 *) Last official synchronization of mod_rewrite with author version (because
7904 mod_rewrite is now directly developed by the author at the Apache Group):
7905 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7906 minus WIN32/NT stuff, but plus copyright removement.
7908 - workaround for detecting infinite rewriting loops
7909 - fixed setting of env vars when "-" is used as subst string
7910 - fixed forced response code on redirects (PR#777)
7911 - fixed cases where r->args is ""
7912 - kludge to disable locking on pipes under braindead SunOS
7913 - fix for rewritelog in cases where remote hostname is unknown
7914 - fixed totally damaged request_rec walk-back loop
7915 o remove static from local data and add static to global ones.
7916 o replaced ugly proxy finding stuff by simple
7917 find_linked_module("mod_proxy") call.
7918 o added missing negation char on rewritelog()
7919 o fixed a few comment typos
7920 [Ralf S. Engelschall]

7925 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to

7950 *) API: In HTTP/1.1, whether or not a request message contains a body
7951 is independent of the request method and based solely on the presence
7952 of a Content-Length or Transfer-Encoding. Therefore, our default
7953 handlers need to be prepared to read a body even if they don't know
7954 what to do with it; otherwise, the body would be mistaken for the

7959 release version number, such that it always increases along the
7960 same lines as our source code branching. [Roy Fielding]
7962 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7964 Changes with Apache 1.2.1
7966 *) SECURITY: Don't serve file system objects unless they are plain files,
7967 symlinks, or directories. This prevents local users from using pipes
7968 or named sockets to invoke programs for an extremely crude form of
7971 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
7972 could contain "../" allowing a local user to "publish" any file on
7973 the system. No slashes are allowed now. [Dean Gaudet]
7975 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7976 (headers, readmes, titles), mod_negotiation (type maps), or
7977 mod_cern_meta (meta files). [Dean Gaudet]
7979 *) SECURITY: Apache will refuse to run as "User root" unless
7980 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7982 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7983 if it contained a .htaccess disallowing symlinks. This is contrary
7984 to the rule that symlink permissions are tested with the symlink
7985 options of the parent directory. [Dean Gaudet] PR#353
7987 *) CONFIG: The LockFile directive can be used to place the serializing
7988 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7989 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7992 *) Request processing now retains state of whether or not the request
7993 body has been read, so that internal redirects and subrequests will
7994 not try to read it twice (and block). [Roy Fielding]
7996 *) Add a placeholder in modules/Makefile to avoid errors with certain
7997 makes. [Marc Slemko]
7999 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
8000 [Dean Gaudet] PR#644
8002 *) mod_include was not properly changing the current directory.
8003 [Marc Slemko] PR#742
8005 *) Attempt to work around problems with third party libraries that do not
8006 handle high numbered descriptors (examples include bind, and
8007 solaris libc). On all systems apache attempts to keep all permanent
8008 descriptors above 15 (called the low slack line). Solaris users
8009 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8010 which keeps all non-FILE * descriptors above 255. On all systems
8011 this should make supporting large numbers of vhosts with many open
8012 log files more feasible. If this causes trouble please report it,
8013 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8014 [Dean Gaudet] various PRs
8016 *) Related to the last entry, network sockets are now opened before
8017 log files are opened. The only known case where this can cause
8018 problems is under Solaris with many virtualhosts and many Listen
8019 directives. But using -DHIGH_SLACK_LINE=256 described above will
8020 work around this problem. [Dean Gaudet]
8022 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8025 *) Improved unix error response logging. [Marc Slemko]
8027 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8028 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8029 when a URL http://... was used in conjunction with a special
8030 redirect flag, e.g. R=permanent, the permanent status was lost.
8031 [Ronald Tschalaer <Ronald.Tschalaer@psi.ch>, Ralf S. Engelschall]
8033 *) If an object has multiple variants that are otherwise equal Apache
8034 would prefer the last listed variant rather than the first.
8037 *) "make clean" at the top level now removes *.o. [Dean Gaudet] PR#752
8039 *) mod_status dumps core in inetd mode. [Marc Slemko and Roy Fielding]
8042 *) pregsub had an off-by-1 in its error checking code. [Alexei Kosut]
8044 *) PORT: fix rlim_t problems with AIX 4.2. [Marc Slemko] PR#333
8046 *) PORT: Update UnixWare support for 2.1.2.

8065 Changes with Apache 1.2
8067 Changes with Apache 1.2b11
8069 *) Fixed open timestamp fd in proxy_cache.c [Chuck Murcko]
8071 *) Added undocumented perl SSI mechanism for -DUSE_PERL_SSI and mod_perl.
8072 [Doug MacEachern, Rob Hartill]
8074 *) Proxy needs to use hard_timeout instead of soft_timeout when it is
8075 reading from one buffer and writing to another, at least until it has
8076 a custom timeout handler. [Roy Fielding and Petr Lampa]
8078 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
8079 apparently due to a mismatch between sigaction and setjmp.
8080 [Roy Fielding] PR#502
8082 *) Log correct status code if we timeout before receiving a request (408)
8083 or if we received a request-line that was too long to process (414).
8084 [Ed Korthof and Roy Fielding] PR#601
8086 *) Virtual hosts with the same ServerName, but on different ports, were
8087 not being selected properly. [Ed Korthof]
8089 *) Added code to return the requested IP address from proxy_host2addr()
8090 if gethostbyaddr() fails due to reverse DNS lookup problems. Original
8091 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8092 [Chuck Murcko] PR#614
8094 *) If multiple requests on a single connection are used to retrieve
8095 data from different virtual hosts, the virtual host list would be
8096 scanned starting with the most recently used VH instead of the first,
8097 causing most virtual hosts to be ignored.
8098 [Paul Sutton and Martin Mares] PR#610
8100 *) The OS/2 handling of process group was broken by a porting patch for
8101 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]
8103 *) Inherit virtual server port from main server if none (or "*") is
8104 given for VirtualHost. [Dean Gaudet] PR#576
8106 *) If the lookup for a DirectoryIndex name with content negotiation
8107 has found matching variants, but none are acceptable, return the
8108 negotiation result if there are no more DirectoryIndex names to lookup.
8109 [Petr Lampa and Roy Fielding]
8111 *) If a soft_timeout occurs after keepalive is set, then the main child
8112 loop would try to read another request even though the connection
8113 has been aborted. [Roy Fielding]
8115 *) Configure changes: Allow for whitespace at the start of a
8116 Module declaration. Also, be more understanding about the
8117 CC=/OPTIM= format in Configuration. Finally, fix compiler
8118 flags if using HP-UX's cc compiler. [Jim Jagielski]
8120 *) Subrequests and internal redirects now inherit the_request from the
8121 original request-line. [Roy Fielding]
8123 *) Test for error conditions before creating output header fields, since
8124 we don't want the error message to include those fields. Likewise,
8125 reset the content_language(s) and content_encoding of the response
8126 before generating or redirecting to an error message, since the new
8127 message will have its own Content-* definitions. [Dean Gaudet]
8129 *) Restored the semantics of headers_out (headers sent only with 200..299
8130 and 304 responses) and err_headers_out (headers sent with all responses).
8131 Avoid the overhead of copying tables if err_headers_out is empty
8132 (the usual case). [Roy Fielding]
8134 *) Fixed a couple places where a check for the default Content-Type was
8135 not properly checking both the value configured by the DefaultType
8136 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8137 of DEFAULT_TYPE to match the documented default (text/plain).
8138 [Dean Gaudet] PR#506
8140 *) Escape the HTML-sensitive characters in the Request-URI that is
8141 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8143 *) Properly initialize the flock structures used by the mutex locking
8144 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8147 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8148 (and NCSA httpd) definition wherein it was the extra path info beyond
8149 the CGI script filename. The environment variable FILEPATH_INFO has
8150 been removed, and instead we supply the original REQUEST_URI to any
8151 script that wants to be Apache-specific and needs the real URI path.
8152 This solves a problem with existing scripts that use extra path info
8153 in the ScriptAlias directive to pass options to the CGI script.
8156 *) The _default_ change in 1.2b10 will change the behaviour on configs
8157 that use multiple Listen statements for listening on multiple ports.
8158 But that change is necessary to make _default_ consistent with other
8159 forms of <VirtualHost>. It requires such configs to be modified
8160 to use <VirtualHost _default_:*>. The documentation has been
8161 updated. [Dean Gaudet] PR#530
8163 *) If an ErrorDocument CGI script is used to respond to an error
8164 generated by another CGI script which has already read the message
8165 body of the request, the server would block trying to read the
8166 message body again. [Rob Hartill]
8168 *) signal() replacement conflicted with a define on QNX (and potentially
8169 other platforms). Fixed. [Ben Laurie] PR#512
8171 Changes with Apache 1.2b10
8173 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8174 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8176 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8178 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
8180 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
8181 config, in case the hostent struct returned is trash.
8182 [Chuck Murcko] PR #491
8184 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8185 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8187 Changes with Apache 1.2b9 [never announced]
8189 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8190 changes and in anticipation of 1.2 final release. [Roy Fielding]
8192 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8193 the connection (e.g., when user presses Stop). Apache will now stop
8194 trying to send a message body immediately after an error from write.
8195 [Roy Fielding and Nathan Kurz] PR#335
8197 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8198 than mod_alias, and mod_alias has higher priority than mod_proxy;
8199 rearranged other modules to enhance understanding of their purpose
8200 and relative order (and maybe even reduce some overhead).
8201 [Roy Fielding and Sameer Parekh]
8203 *) Fix graceful restart. Eliminate many signal-related race
8204 conditions in both forms of restart, and in SIGTERM. See
8205 htdocs/manual/stopping.html for details on stopping and
8206 restarting the parent. [Dean Gaudet]
8208 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8209 memory allocator to avoid a behaviour that required extra blocks to
8210 be allocated. [Dean Gaudet]
8212 *) Allow suexec to access files relative to current directory but not
8213 above. (Excluding leading / or any .. directory.) [Ken Coar]
8216 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8217 PR#367, 368, 354, 453
8219 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8220 while obtaining the /~user and save the username in a separate data
8221 area so that it won't be overwritten by the call to getgrgid(), and
8222 fix some misuse of the pool string allocation functions. Also fixes
8223 a general problem with parsing URL query info into args for CGI scripts.
8224 [Roy Fielding] PR#339, 367, 354, 453
8226 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
8228 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
8230 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
8231 AuthDBAuthoritative. [Marc Slemko] PR#420
8233 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8235 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8236 object that can't be PUT, or FOOBAR for some method FOOBAR that
8237 apache doesn't know about at all). Log 404s that occur in mod_include.
8238 [Paul Sutton, John Van Essen]
8240 *) If a soft timeout (or lingerout) occurs while trying to flush a
8241 buffer or write inside buff.c or fread'ing from a CGI's output,
8242 then the timeout would be ignored. [Roy Fielding] PR#373
8244 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8245 parsing of headers. If the terminating empty-line CRLF occurs starting
8246 at the 256th or 257th byte of output, then Navigator will think a normal
8247 image is invalid. We are guessing that this is because their initial
8248 read of a new request uses a 256 byte buffer. We check the bytes written
8249 so far and, if we are about to tickle the bug, we instead insert a
8250 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8252 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8253 of an external redirection. [Roy Fielding and Paul Sutton]
8255 *) Configure would create a broken Makefile if the configuration file
8256 contained a commented-out Rule. [Roy Fielding]
8258 *) Promote per_dir_config and subprocess_env from the subrequest to the
8259 main request in mod_negotiation. In particular this fixes a bug
8260 where <Files> sections wouldn't properly apply to negotiated content.
8263 *) Fix a potential deadlock in mod_cgi script_err handling.
8264 [Ralf S. Engelschall]
8266 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8269 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8270 .htaccess files because the RewriteBase was not replaced correctly.
8271 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8272 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8274 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8275 1.x the settings are those of pre-1.2b8. For 2.x we include
8276 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8277 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8278 [Dean Gaudet] PR#336, PR#340
8280 *) Redirect did not preserve ?query_strings when present in the client's
8281 request. [Dean Gaudet]
8283 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8285 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8287 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8289 *) Add mod_example (illustration of API techniques). [Ken Coar]
8291 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8293 *) Improve handling of directories when filenames have spaces in them.
8296 *) For hosts with multiple IP addresses, try all additional addresses if
8297 necessary to get a connect. Fail only if hostent address list is
8298 exhausted. [Chuck Murcko]
8300 *) More signed/unsigned port fixes. [Dean Gaudet]
8302 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8305 Changes with Apache 1.2b8
8307 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8308 to it. [Marc Slemko]
8310 *) The addition of <Location> and <File> directives made the
8311 sub_req_lookup_simple() function bogus, so we now handle
8312 the special cases directly. [Dean Gaudet]
8314 *) We now try to log where the server is dumping core when a fatal
8315 signal is received. [Ken Coar]
8317 *) Improved lingering_close by adding a special timeout, removing the
8318 spurious log messages, removing the nonblocking settings (they
8319 are not needed with the better timeout), and adding commentary
8320 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8321 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8323 *) Send error messages about setsockopt failures to the server error
8324 log instead of stderr. [Roy Fielding]
8326 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8328 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8329 processing a subrequest, allocate memory from r->main->pool instead
8330 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8331 in the middle of an SSI request. [Dean Gaudet] PR #122
8333 *) Fixed status of response when POST is received for a nonexistent URL
8334 (was sending 405, now 404) and when any method is sent with a
8335 full-URI that doesn't match the server and the server is not acting
8336 as a proxy (was sending 501, now 403). [Roy Fielding]
8338 *) Host port changed to unsigned short. [Ken Coar] PR #276
8340 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8342 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8344 *) Report extra info from errno with many errors that cause httpd to exit.
8345 spawn_child, popenf, and pclosef now have valid errno returns in the
8346 event of an error. Correct problems where errno was stomped on
8347 before being reported. [Dean Gaudet]
8349 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8350 never called, and thus the filesystem would remain full indefinitely.
8351 We now also remove incomplete cache files left if the origin server
8352 didn't send a Content-Length header and either the client has aborted
8353 transfer or bwrite() to client has failed. [Petr Lampa]
8355 *) Fixed the handling of module and script-added header fields.
8356 Improved the interface for sending header fields and reduced
8357 the duplication of code between sending okay responses and errors.
8358 We now always send both headers_out and err_headers_out, and
8359 ensure that the server-reserved fields are not being overridden,
8360 while not overriding those that are not reserved. [Roy Fielding]
8362 *) Moved transparent content negotiation fields to err_headers_out
8363 to reflect above changes. [Petr Lampa]
8365 *) Fixed the determination of whether or not we should make the
8366 connection persistent for all of the cases where some other part
8367 of the server has already indicated that we should not. Also
8368 improved the ordering of the test so that chunked encoding will
8369 be set whenever it is desired instead of only when KeepAlive
8370 is enabled. Added persistent connection capability for most error
8371 responses (those that do not indicate a bad input stream) when
8372 accessed by an HTTP/1.1 client. [Roy Fielding]
8374 *) Added missing timeouts for sending header fields, error responses,
8375 and the last chunk of chunked encoding, each of which could have
8376 resulted in a process being stuck in write forever. Using soft_timeout
8377 requires that the sender check for an aborted connection rather than
8378 continuing after an EINTR. Timeouts that used to be initiated before
8379 send_http_header (and never killed) are now initiated only within or
8380 around the routines that actually do the sending, and not allowed to
8381 propagate above the caller. [Roy Fielding]
8383 *) mod_auth_anon required an @ or a . in the email address, not both.
8386 *) per_dir_defaults weren't set correctly until directory_walk for
8387 name-based vhosts. This fixes an obscure bug with the wrong config
8388 info being used for vhosts that share the same ip as the server.
8391 *) Improved generation of modules/Makefile to be more generic for
8392 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8394 *) Generate makefile dependency for Configuration based on the actual
8395 name given when running the Configure process. [Dean Gaudet]
8397 *) Fixed problem with vhost error log not being set prior to
8398 initializing virtual hosts. [Dean Gaudet]
8400 *) Fixed infinite loop when a trailing slash is included after a type map
8401 file URL (extra path info). [Petr Lampa]
8403 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8405 *) Add documentation for DNS issues (reliability and security), and try
8406 to explain the virtual host matching process. [Dean Gaudet]
8408 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8409 fails while parsing the configuration file. [Dean Gaudet]
8411 *) Improved calls to setsockopt. [Roy Fielding]
8413 *) Negotiation changes: Don't output empty content-type in variant list;
8414 Output charset in variant list; Return sooner from handle_multi() if
8415 no variants found; Add handling of '*' wildcard in Accept-Charset.
8416 [Petr Lampa and Paul Sutton]
8418 *) Fixed overlaying of request/sub-request notes and headers in
8419 mod_negotiation. [Dean Gaudet]
8421 *) If two variants' charset quality are equal and one is the default
8422 charset (iso-8859-1), then prefer the variant that was specifically
8423 listed in Accept-Charset instead of the default. [Petr Lampa]
8425 *) Memory allocation problem in push_array() -- it would corrupt memory
8426 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8428 *) invoke_handler() doesn't handle mime arguments in content-type
8431 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8434 *) Fixed problem with ErrorDocument not working for virtual hosts
8435 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8437 *) Log an error message if we get a request header that is too long,
8438 since it may indicate a buffer overflow attack. [Marc Slemko]
8440 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8441 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8442 [Ken Coar] PR #146, #187

8448 [Garey Smiley] PR #59
8450 *) Fixed error message when resource is not found and URL contains
8451 path info. [Petr Lampa and Dean Gaudet] PR #40
8453 *) Fixed user and server confusion over what should be a virtual host
8454 and what is the main server, resulting in access to something
8455 other than the name defined in the virtualhost directive (but
8456 with the same IP address) failing. [Dean Gaudet]
8458 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8459 AIX; improves the redirection stuff to enable the users to generally
8460 redirect to http, https, gopher and ftp; added TIME variable for
8461 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8462 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8463 can be used in conjunction with %{TIME} or other variables to create
8464 time-dependent rewriting rules. [Ralf S. Engelschall]
8466 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8467 Module authors may need to adjust their code for proper cleanup to take
8468 place (that is, call note_cleanups_for_fd()). This change fixes problems
8469 with file descriptors being erroneously closed when the proxy module was
8470 in use. [Ben Laurie]
8472 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8473 initgroups() to hose the group information needed for later
8474 comparisons. [Randy Terbush]
8476 *) Remove unnecessary call to va_end() in create_argv() which
8477 caused a SEGV on some systems.
8479 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8482 *) Clear memory allocated for listeners. [Randy Terbush]

8498 - merge notes, headers_out and err_headers_out
8500 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8501 "HTTP/#.# ###*" to be more lenient about what we accept.
8504 *) more proxy FTP bug fixes:
8505 - Changed send_dir() to remove user/passwd from displayed URL.
8506 - Changed login error messages to be more descriptive.
8507 - remove setting of SO_DEBUG socket option
8508 - Make ftp_getrc() more lenient about multiline responses,
8509 specifically, 230 responses which don't have continuation 230-
8510 on each line). These seem to be all NT FTP servers, and while
8511 perhaps questionable, they appear to be legal by RFC 959.
8512 - Add missing kill_timeout() after transfer to user completes.
8515 *) Fixed problem where a busy server could hang when restarting
8516 after being sent a SIGHUP due to child processes not exiting.
8519 *) Modify mod_include escaping so a '\' only signifies an escaped
8520 character if the next character is one that needs
8521 escaping. [Ben Laurie]
8523 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8524 used with a 'base' directive that does not have a '/' in it.
8525 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8527 *) Reduced the default timeout from 1200 seconds to 300, and the
8528 one in the sample configfile from 400 to 300. [Marc Slemko]
8530 *) Stop vbprintf from crashing if given a NULL string pointer;
8531 print (null) instead. [Ken Coar]
8533 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8534 [Marc Slemko and Roy Fielding]
8536 *) Fixed problem with mod_cgi-generated internal redirects trying to
8537 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8539 *) Reduced timeout on lingering close, removed possibility of a blocked
8540 read causing the child to hang, and stopped logging of errors if
8541 the socket is not connected (reset by client). [Roy Fielding]
8543 *) Rearranged main child loop to remove duplication of code in
8544 select/accept and keep-alive requests, fixed several bugs regarding
8545 checking scoreboard_image for exit indication and failure to
8546 account for all success conditions and trap all error conditions,
8547 prevented multiple flushes before closing the socket; close the entire
8548 socket buffer instead of just one descriptor, prevent logging of
8549 EPROTO and ECONNABORTED on platforms where supported, and generally
8550 improved readability. [Roy Fielding]
8552 *) Extensive performance improvements. Cleaned up inefficient use of
8553 auto initializers, multiple is_matchexp calls on a static string,
8554 and excessive merging of response_code_strings. [Dean Gaudet]
8556 *) Added double-buffering to mod_include to improve performance on
8557 server-side includes. [Marc Slemko]
8559 *) Several fixes for suexec wrapper. [Randy Terbush]
8560 - Make wrapper work for files on NFS filesystem.
8561 - Fix portability problem of MAXPATHLEN.
8562 - Fix array overrun problem in clean_env().
8563 - Fix allocation of PATH environment variable
8565 *) Removed extraneous blank line is description of mod_status chars.
8568 *) Logging of errors from the call_exec routine simply went nowhere,
8569 since the logfile fd has been closed, so now we send them to stderr.
8570 [Harald T. Alvestrand]
8572 *) Fixed core dump when DocumentRoot is a CGI.
8573 [Ben Laurie, reported by geddis@tesserae.com]
8575 *) Fixed potential file descriptor leak in mod_asis; updated it and
8576 http_core to use pfopen/pfclose instead of fopen/fclose.
8577 [Randy Terbush and Roy Fielding]
8579 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8580 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8581 [Dean Gaudet and Ken Coar]
8583 *) Return a 302 response code to the client when sending a redirect
8584 due to a missing trailing '/' on a directory instead of a 301; now
8585 it is cacheable. [Markus Gyger]
8587 *) Fix condition where, if a bad directive occurs in .htaccess, and
8588 sub_request() goes first to this directory, then log_reason() will
8589 SIGSEGV because it doesn't have initialized r->per_dir_config.
8590 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8592 *) Fix handling of lang_index in is_variant_better(). This was
8593 causing problems which resulted in the server sending the
8594 wrong language document in some cases. [Petr Lampa]
8596 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8597 the clean environment on some systems.
8599 *) Tweak byteserving code (e.g. serving PDF files) to work around
8600 bugs in Netscape Navigator and Microsoft Internet Explorer.
8601 Emit Content-Length header when sending multipart/byteranges.
8604 *) Port to HI-UX/WE2. [Nick Maclaren]
8606 *) Port to HP MPE operating system for HP 3000 machines
8607 [Mark Bixby <markb@cccd.edu>]
8609 *) Fixed bug which caused a segmentation fault if only one argument
8610 given to RLimit* directives. [Ed Korthof]
8612 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8614 *) Improved buffered output to the client by delaying the flush decision
8615 until the BUFF code is actually about to read the next request.
8616 This fixes a problem introduced in 1.2b5 with clients that send
8617 an extra CRLF after a POST request. Also improved chunked output
8618 performance by combining writes using writev() and removing as
8619 many bflush() calls as possible. NOTE: Platforms without writev()
8620 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8621 or Configure, unless we have already done so. [Dean Gaudet]
8623 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8625 *) Fixed mod_info output corruption bug introduced by buffer overflow
8626 fixes. [Dean Gaudet]
8628 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8629 for the special case of a 304 response. [Paul Sutton]
8631 *) Improved handling of TRACE method by bypassing normal method handling
8632 and header parsing routines; fixed Allow response to always allow TRACE.
8635 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8637 *) Cleaned-up some of the generated HTML. [Ken Coar]
8639 Changes with Apache 1.2b6
8641 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8643 *) Fix typo introduced in fix for potential infinite loop around
8644 accept() in child_main(). This change caused the rev to 1.2b6.
8645 1.2b5 was never a public beta.
8647 Changes with Apache 1.2b5
8649 *) Change KeepAlive semantics (On|Off instead of a number), add
8650 MaxKeepAliveRequests directive. [Alexei Kosut]
8652 *) Various NeXT compilation patches, as well as a change in
8653 regex/regcomp.c since that file also used a NEXT define.
8656 *) Allow * to terminate the end of a directory match in mod_dir.
8657 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8659 *) Don't call can_exec() if suexec_enabled. Calling this requires
8660 scripts executed by the suexec wrapper to be world executable, which
8661 defeats one of the advantages of running the wrapper. [Randy Terbush]
8663 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8666 *) Migration from sprintf() to snprintf() to avoid buffer
8667 overflows. [Marc Slemko]
8669 *) Provide portable snprintf() implementation (ap_snprintf)
8670 as well as *cvt family. [Jim Jagielski]
8672 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8675 *) Remove mod_fastcgi.c from the distribution. This module appears
8676 to be maintained more through the Open Market channels and should
8677 continue to be easily available at http://www.fastcgi.com/
8679 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8680 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8682 *) mod_info assumed that the config files were relative to ServerRoot.
8685 *) CGI scripts called as an error document resulting from failed
8686 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8688 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8691 *) Properly check errno to prevent display of a directory index
8692 when server receives a long enough URL to confuse stat().
8695 *) Several security enhancements to suexec wrapper. It is _highly_
8696 recommended that previously installed versions of the wrapper
8697 be replaced with this version. [Randy Terbush, Jason Dour]
8699 - ~user execution now properly restricted to ~user's home
8700 directory and below.
8701 - execution restricted to UID/GID > 100
8702 - restrict passed environment to known variables
8703 - call setgid() before initgroups() (portability fix)
8704 - remove use of setenv() (portability fix)
8706 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8708 *) Add access control via environment variables. [Ben Laurie]
8710 *) Add rflush() function. [Alexei Kosut]
8712 *) remove duplicate pcalloc() call in new_connection().
8714 *) Fix incorrect comparison which could allow number of children =
8715 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8716 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8718 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8719 AIX PS/2, CONVEXOS. [Jim Jagielski]
8721 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8722 It's more portable. [Martin Kraemer]
8724 *) Replace references to make in Makefile.tmpl with $(MAKE).
8727 *) Add ProxyBlock directive w/IP address caching. Add IP address
8728 caching to NoCache directive as well. ProxyBlock works with all
8729 handlers; NoCache now also works with FTP for anonymous logins.
8730 Still more code cleanup. [Chuck Murcko]
8732 *) Add "header parse" API hook [Ben Laurie]
8734 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8736 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8738 *) Correctly allow access and auth directives in <Files> sections in
8739 server config files. [Alexei Kosut]
8741 *) Fix bug with ServerPath that could cause certain files to be not
8742 found by the server. [Alexei Kosut]
8744 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8745 double-quote from text and so that it properly checks for unsupported
8746 status codes using the new index_of_response interface. [Roy Fielding]
8748 *) Multiple fixes to the lingering_close code in order to avoid being
8749 interrupted by a stray timeout, to avoid lingering on a connection
8750 that has already been aborted or never really existed, to ensure that
8751 we stop lingering as soon as any error condition is received, and to
8752 prevent being stuck indefinitely if the read blocks. Also improves
8753 reporting of error conditions. [Marc Slemko and Roy Fielding]
8755 *) Fixed initialization of parameter structure for sigaction.
8756 [mgyger@itr.ch, Adrian Filipi-Martin]
8758 *) Fixed reinitializing the parameters before each call to accept and
8759 select, and removed potential for infinite loop in accept.
8760 [Roy Fielding, after useful PR from adrian@virginia.edu]
8762 *) Fixed condition where, if a child fails to fork, the scoreboard would
8763 continue to say SERVER_STARTING forever. Eventually, the main process
8764 would refuse to start new children because count_idle_servers() will
8765 count those SERVER_STARTING entries and will always report that there
8766 are enough idle servers. [Phillip Vandry]
8768 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8769 Avoided calling bflush() when the client is pipelining requests.
8770 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8772 *) Added description of "." mode in server-status [Jim Jagielski]
8774 Changes with Apache 1.2b4
8776 *) Fix possible race condition in accept_mutex_init() that
8777 could leave a small security hole open allowing files to be
8778 overwritten in cases where the server UID has write permissions.
8781 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8783 *) Fix portablity problem in util_script where ARG_MAX may not be
8784 defined for some systems.
8786 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8789 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8790 style magic #! token for better script portability. [Garey Smiley]
8792 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8793 execution for ~userdir CGI. [Jason Dour]
8795 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8797 *) Fix month off by one in suexec wrapper logging.
8799 Changes with Apache 1.2b3:
8801 *) Fix error in mod_cgi which could cause resources not to be properly
8802 freed, or worse. [Dean Gaudet]
8804 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8806 *) Add set_flag_slot() at the request of Dirk and others.
8809 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8811 *) Add changes to improve the error message given for invalid
8812 ServerName parameters. [Dirk vanGulik]
8814 *) Add "Authoritative" directive for Auth modules that don't
8815 currently have it. This gives admin control to assign authoritative
8816 control to an authentication scheme and allow "fall through" for
8817 those authentication modules that aren't "Authoritative" thereby
8818 allowing multiple authentication mechanisms to be chained.
8821 *) Remove requirement for ResourceConfig/AccessConfig if not using
8822 the three config file layout. [Randy Terbush]
8824 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8826 *) Changes to suexec wrapper to fix the following problems:
8827 1. symlinked homedirs will kill ~userdirs.
8828 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8829 3. CGI command lines paramters problems
8830 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8831 [Randy Terbush, Jason Dour]
8833 *) Change create_argv() to accept variable arguments. This fixes
8834 a problem where arguments were not getting passed to the CGI via
8835 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8837 *) Collapse multiple slashes in path URLs to properly apply
8838 handlers defined by <Location>. [Alexei Kosut]
8840 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8842 *) Improve the accuracy of request duration timings by setting
8843 r->request_time in read_request_line() instead of read_request().
8846 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8847 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8849 *) Add the ability to pass different Makefile.tmpl files to Configure
8850 using the -make flag. [Rob Hartill]
8852 *) Fix coredump triggered when sending a SIGHUP to the server caused
8853 by an assertion failure, in turn caused by an uninitialised field in a
8857 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8858 PATH_INFO from previous versions of Apache (in certain situations,
8859 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8860 [later removed in 1.2b11]
8862 *) Add rwrite() function to API to allow for sending strings of
8863 arbitrary length. [Doug MacEachern]
8865 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8867 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8868 NeXT. [Jim Jagielski]
8870 *) Removed recent modification to promote the status code on internal
8871 redirects, since the correct fix was to change the default log format
8872 in mod_log_config so that it outputs the original status. [Rob Hartill]
8874 Changes with Apache 1.2b2:
8876 *) Update set_signals() to use sigaction() for setting handlers.
8877 This appears to fix a re-entrant problem in the seg_fault()
8878 bus_error() handlers. [Randy Terbush]
8880 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8882 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8884 *) proxy_http.c bugfixes: [Chuck Murcko]
8885 1) fixes possible NULL pointer reference w/NoCache
8886 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8887 host would cache nothing if it was in the local domain,
8888 and the local domain was in the NoCache list)
8889 3) Adds Host: header when not available
8890 4) Some code cleanup and clarification
8892 *) mod_include.c bugfixes:
8893 1) Fixed an ommission that caused include variables to not
8894 be parsed in config errmsg directives [Howard Fear]
8895 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8896 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8897 4) Allow backslash-escaping to all quoted text
8898 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8899 5) Pass variable to command line if not set in XSSI's env
8902 *) Fix infinite loop when processing Content-language lines in
8903 type-map files. [Alexei Kosut]
8905 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8907 *) Fixed problem in set_[user|group] that prevented CGI execution
8908 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8910 *) Added PORTING information file. [Jim Jagielski]
8912 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8914 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8916 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8917 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8919 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8920 which caused problems of systems where socket s_addr is >32bits.
8922 *) Added comment to explain (r->chunked = 1) side-effect in
8923 http_protocol.c [Roy Fielding]
8925 *) Replaced use of index() in mod_expires.c with more appropriate
8926 and portable isdigit() test. [Ben Laurie]
8928 *) Updated Configure for ...
8929 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8930 *-dg-dgux* (bad pattern match)
8931 QNX (DEF_WANTHSREGEX=yes)
8932 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8935 and added some user diagnostic info. [Ben Laurie]
8937 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8938 for better portability. [Jim Jagielski]
8940 *) Updated helpers/GuessOS for ...
8941 SCO 5 (recognize minor releases)
8942 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8943 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8944 IRIX64 (-sgi-irix64)
8945 ULTRIX (-unknown-ultrix)
8946 SINIX (-whatever-sysv4)
8947 NCR Unix (-ncr-sysv4)
8948 and fixed something in helpers/PrintPath [Ben Laurie]
8950 Changes with Apache 1.2b1
8952 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8954 Changes with Apache 1.1.1
8956 *) Fixed bug where Cookie module would make two entries in the
8957 logfile for each access [Mark Cox]

8960 leak. [Nathan Neulinger]
8962 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8964 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8966 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8968 Changes with Apache 1.1.0
8970 *) Bring NeXT support up to date. [Takaaki Matsumoto]

8975 [Alexei Kosut, Ben Laurie]
8977 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8979 *) Fix missing address family for connect, also remove unreachable statement
8980 in mod_proxy. [Ben Laurie]
8982 *) mod_env now turned on by default in Configuration.tmpl.
8984 *) Bugs which were fixed:
8985 a) yet more mod_proxy bugs [Ben Laurie]
8986 b) CGI works again with inetd [Alexei Kosut]
8987 c) Leading colons were stripped from passwords [osm@interguide.com]
8988 d) Another fix to multi-method Limit problem [jk@tools.de]
8990 Changes with Apache 1.1b4
8992 *) r->bytes_sent variable restored. [Robert Thau]
8994 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8996 *) More possibly unsecure programs removed from the support directory.
8998 *) More mod_auth_msql authentication improvements.
9000 *) VirtualHosts based on Host: headers no longer conflict with the
9003 *) OS/2 compatibility enhancements. [Gary Smiley]
9005 *) POST now allowed to directory index CGI scripts.
9007 *) Actions now work with files of the default type.
9009 *) Bugs which were fixed:
9010 a) more mod_proxy bugs
9011 b) early termination of inetd requests
9012 c) compile warnings on several systems
9013 d) problems when scripts stop reading output early
9015 Changes with Apache 1.1b3
9017 *) Much of cgi-bin and all of cgi-src has been removed, due to
9018 various security holes found and that we could no longer support
9021 *) The "Set-Cookie" header is now special-cased to not merge multiple
9022 instances, since certain popular browsers can not handle multiple
9023 Set-Cookie instructions in a single header. [Paul Sutton]
9025 *) rprintf() added to buffer code, occurrences of sprintf removed.
9028 *) CONNECT method for proxy module, which means tunneling SSL should work.
9029 (No crypto needed) Also a NoCache config directive.
9031 *) Several API additions: pstrndup(), table_unset() and get_token()
9032 functions now available to modules.
9034 *) mod_imap fixups, in particular Location: headers are now complete
9037 *) New "info" module which reports on installed module set through a
9038 special URL, a la mod_status.
9040 *) "ServerPath" directive added - allows for graceful transition
9041 for Host:-header-based virtual hosts.
9043 *) Anonymous authentication module improvements.
9045 *) MSQL authentication module improvements.
9047 *) Status module design improved - output now table-based. [Ben Laurie]
9049 *) htdigest utility included for use with digest authentication
9052 *) mod_negotiation: Accept values with wildcards to be treated with
9053 less priority than those without wildcards at the same quality
9054 value. [Alexei Kosut]
9056 *) Bugs which were fixed:
9057 a) numerous mod_proxy bugs
9058 b) CGI early-termination bug [Ben Laurie]
9059 c) Keepalives not working with virtual hosts
9060 d) RefererIgnore problems
9061 e) closing fd's twice in mod_include (causing core dumps on
9062 Linux and elsewhere).
9064 Changes with Apache 1.1b2
9067 a) core dumps in mod_digest
9068 b) truncated hostnames/ip address in the logs
9069 c) relative URL's in mod_imap map files
9071 Changes with Apache 1.1b1
9073 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9075 Changes with Apache 1.0.3
9077 *) Internal redirects which occur in mod_dir.c now preserve the
9078 query portion of a request (the bit after the question mark).
9081 *) Escape active characters '<', '>' and '&' in html output in
9082 directory listings, error messages and redirection links.
9085 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9087 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9090 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9092 *) Reset timeout timer after each successful fwrite() to the network.
9093 This patch adds a reset_timeout() procedure that is called by
9094 send_fd() to reset the timeout ever time data is written to the net.
9097 *) timeout() signal handler now checks for SIGPIPE and reports
9098 lost connections in a more user friendly way. [Rob Hartill]
9100 *) Location of the "scoreboard" file which used to live in /tmp is
9101 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9102 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9104 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9106 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9107 which caused a SEGV with cookies enabled
9109 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9112 *) Log the UNIX textual error returned by some system calls, in
9113 particular errors from accept() [David Robinson]
9115 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9117 Changes with Apache 1.0.2
9119 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9120 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9122 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9125 *) past changes to http_config.c to only use the
9126 setrlimit function on systems defining RLIMIT_NOFILE
9127 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9128 for SUNOS and prototypes the needed functions.
9130 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9133 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9135 *) Merge multiple headers from CGI scripts instead of taking last
9136 one. [David Robinson]
9138 *) Add support for SCO 5. [Ben Laurie]
9140 Changes with Apache 1.0.1
9142 *) Silence mod_log_referer and mod_log_agent if not configured
9145 *) Recursive includes can occur if the client supplies PATH_INFO data
9146 and the server provider uses relative links; as file.html
9147 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9149 *) The replacement for initgroups() did not call {set,end}grent(). This
9150 had two implications: if anything else used getgrent(), then
9151 initgroups() would fail, and it was consuming a file descriptor.
9154 *) On heavily loaded servers it was possible for the scoreboard to get
9155 out of sync with reality, as a result of a race condition.
9156 The observed symptoms are far more Apaches running than should
9157 be, and heavy system loads, generally followed by catastrophic
9158 system failure. [Ben Laurie]
9160 *) Fix typo in license. [David Robinson]
9162 Changes with Apache 1.0.0 23 Nov 1995
9164 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9166 Changes with Apache 0.8.16 05 Nov 1995
9168 *) New man page for 'httpd' added to support directory [David Robinson]
9170 *) .htgroup files can have more than one line giving members for a
9171 given group (each must have the group name in front), for NCSA
9172 back-compatibility [Robert Thau]
9174 *) Mutual exclusion around accept() is on by default for SVR4 systems
9175 generally, since they generally can't handle multiple processes in
9176 accept() on the same socket. This should cure flaky behavior on
9177 a lot of those systems. [David Robinson]
9179 *) AddType, AddEncoding, and AddLanguage directives take multiple
9180 extensions on a single command line [David Robinson]
9182 *) UserDir can be disabled for a given virtual host by saying
9183 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9184 that this didn't work. [David Robinson]
9186 *) Compiles on QNX [Ben Laurie]
9188 *) Corrected parsing of ctime time format [David Robinson]
9190 *) httpd does a perror() before exiting if it can't log its pid
9191 to the PidFile, to make diagnosing the error a bit easier.
9194 *) <!--#include file="..."--> can no longer include files in the
9195 parent directory, for NCSA back-compatibility. [David Robinson]
9197 *) '~' is *not* escaped in URIs generated for directory listings
9200 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9202 *) Fixed bug involving handling URIs with escaped %-characters
9203 in redirects [David Robinson]
9205 Changes with Apache 0.8.15 14 Oct 1995
9207 *) Switched to new, simpler license
9209 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9211 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9213 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9215 *) Correctly handles internal redirects to files with names containing '%'
9218 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9220 *) Use geteuid() rather than getuid() to see if we have root privilege,
9221 so that server correctly resets privilege if run setuid root. [Andrew
9224 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9227 *) Fix relative URLs in imagemap files [Randy Terbush]
9229 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9232 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9233 entries all name the same one. [David Robinson]
9235 *) Fix directory listings with filenames containing unusual characters
9238 *) Better URI-escaping for generated URIs in directories with filenames
9239 containing unusual characters [Ben Laurie]
9241 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9243 *) Unblock alarms on error return from spawn_child() [David Robinson]
9245 *) Sample Config files have extra note for SCO users [Ben Laurie]
9247 *) Configuration has note for HP-UX users [Rob Hartill]
9249 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9251 *) Nuked bogus #define in httpd.h [David Robinson]
9253 *) Better test for whether a system has setrlimit() [David Robinson]
9255 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9257 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9260 Changes with Apache 0.8.14 19 Sep 1995
9262 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9264 *) AddDescription works (better) [Ben Laurie]
9266 *) Leaves an intelligible error diagnostic when it can't set group
9267 privileges on standalone startup [Andrew Wilson]
9269 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9270 that machine, which claims to be BSD but does not support RLIMIT.
9273 *) gcc -Wall no longer complains about an unused variable when util.c
9274 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9276 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9278 Changes with Apache 0.8.13 07 Sep 1995
9280 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9282 *) Have built-in imagemap code recognize & honor Point directive [James
9285 *) Generate cleaner directory listings in directories with a mix of
9286 long and short filenames [Rob Hartill]
9288 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9290 *) Properly default ServerName for virtual servers [Robert Thau]
9292 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9293 Paul Richards and a cast of thousands...]
9295 *) On self-identified BSD systems (we don't try to guess any more),
9296 allocate a few extra file descriptors per virtual host with setrlimit,
9297 if we can, to avoid running out. [Randy Terbush]
9299 *) Write 22-character lock file name into buffer with enough space
9300 on startup [Konstantin Olchanski]
9302 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9305 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9307 *) Suppress -Wall warning by initializing variable in negotiation code
9308 [Tobias Weingartner]
9310 Changes with Apache 0.8.12 31 Aug 1995
9312 *) Doesn't pause three seconds after including a CGI script which is
9313 too slow to die off (this is done by not even trying to kill off
9314 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9315 after the entire document has been processed). [Robert Thau]
9317 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9319 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9321 *) Allows .htaccess files to override <Directory> sections naming the
9322 same directory [David Robinson]
9324 *) Removed an efficiency hack in sub_req_lookup_uri which was
9325 causing certain extremely marginal cases (e.g., ScriptAlias of a
9326 *particular* index.html file) to fail. [David Robinson]
9328 *) Doesn't log an error when the requested URI requires
9329 authentication, but no auth header line was supplied by the
9330 client; this is a normal condition (the client doesn't no auth is
9331 needed here yet). [Robert Thau]
9333 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9335 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9337 *) RFC931 code no longer passes out name of prior clients on current
9338 requests if the current request came from a server that doesn't
9339 do RFC931. [David Robinson]
9341 *) Configuration script accepts "Module" lines with trailing whitespace.
9344 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9346 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9348 Changes with Apache 0.8.11 24 Aug 1995
9350 *) Wildcard <Directory> specifications work. [Robert Thau]
9352 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9354 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9355 the file being requested itself, in addition to the directories leading
9356 up to it. [Robert Thau]
9358 *) Logs access failures due to symlink checks or invalid client address
9359 in the error log [Roy Fielding, Robert Thau]
9361 *) Symlink checks deal correctly with systems where lstat of
9362 "/path/to/some/link/" follows the link. [Thau, Fielding]
9364 *) Doesn't reset DirectoryIndex to 'index.html' when
9365 other directory options are set in a .htaccess file. [Robert Thau]
9367 *) Clarified init code and nuked bogus warning in mod_access.c
9370 *) Corrected several directives in sample srm.conf
9371 --- includes corrections to directory indexing icon-related directives
9372 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9373 icons for encodings right, and turning on AddEncoding by default).
9376 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9379 *) INSTALL & README mention "contributed modules" directory [Brian
9382 *) Fixed English in the license language... "for for" --> "for".
9385 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9386 mod_alias.c, merging it almost completely with handling of Alias, and
9387 adding a 'notes' field to the request_rec which allows the CGI module
9388 to discover whether the Alias module has put this request through
9389 ScriptAlias (which it needs to know for back-compatibility, as the old
9390 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9393 Changes with Apache 0.8.10 18 Aug 1995
9395 *) AllowOverride applies to the named directory, and not just
9396 subdirectories. [David Robinson]
9398 *) Do locking for accept() exclusion (on systems that need it)
9399 using a special file created for the purpose in /usr/tmp, and
9400 not the error log; using the error log causes real problems
9401 if it's NFS-mounted; this is known to be the cause of a whole
9402 lot of "server hang" problems with Solaris. [David Robinson;
9403 thanks to Merten Schumann for help diagnosing the problem].
9405 Changes with Apache 0.8.9 12 Aug 1995
9407 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9409 *) Nested includes see environment variables of the including document,
9410 for NCSA bug-compatibility (some sites have standard footer includes
9411 which try to print out the last-modified date). [Eric Hagberg/Robert
9414 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9415 URI as a CGI script, even if it would have been treated as something
9416 else if requested directly, for NCSA back-compatibility. (Note that
9417 this means that people who know the name of the script can see the
9418 code just by asking for it). [Robert Thau]
9420 *) New version of dbmmanage script included in support directory as
9423 *) Check if scoreboard file couldn't be opened, and say so, rather
9424 then going insane [David Robinson]
9426 *) POST to CGI works on A/UX [Jim Jagielski]
9428 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9430 *) NCSA server push works properly --- the Arena bug compatibility
9431 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9432 if you still want the workaround). [Rob Hartill]
9434 *) If client didn't submit any Accept-encodings, ignore encodings in
9435 content negotiation. (NB this will all have to be reworked anyway
9436 for the new HTTP draft). [Florent Guillaume]
9438 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9440 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9442 *) Give Redirect priority over Alias, for NCSA bug compatibility
9445 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9446 paralleling earlier bug fix for CGI [David Robinson]
9448 *) If DBM auth is improperly configured, report a server error and don't
9451 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9452 it seems to work well enough without it (even in a 10 hits/sec
9453 workout), and the overhead for the locking under A/UX is
9454 alarmingly high (though it is very low on other systems).
9455 [Eric Hagberg, Jim Jagielski]
9457 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9459 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9460 Behlendorf/Eric Hagberg]
9462 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9464 *) Compiles clean on NEXT [Rob Hartill]
9466 *) Compiles clean on SGI [Robert Thau]
9468 Changes with Apache 0.8.8 08 Aug 1995
9470 *) SunOS library prototypes now never included unless explicitly
9471 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9472 people using GNU libc on SunOS are screwed by prototypes for the
9475 (Those who wish to compile clean with gcc -Wall on a standard
9476 SunOS setup need the prototypes, and may obtain them using
9477 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9478 with nonstandard libraries are presumably competent to make their
9481 *) Strips trailing '/' characters off both args to the Alias command,
9482 to make 'Alias /foo/ /bar/' work.
9484 Changes with Apache 0.8.7 03 Aug 1995
9486 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9487 [reported by David Robinson]
9489 *) Compiles clean on OSF/1 [David Robinson]
9491 *) Added some of the more recent significant changes (AddLanguage stuff,
9492 experimental LogFormat support) to CHANGES file in distribution root
9495 Changes with Apache 0.8.6 02 Aug 1995
9497 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9498 (If you actually wanted a conditional GET which bypassed the cache, you
9499 couldn't get it). [Reported by Roy Fielding]
9501 *) Properly terminate headers on '304 Not Modified' replies to conditional
9502 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9503 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9505 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9507 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9508 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9509 and older versions don't set the __SUNPRO_C preprocessor variable). On
9510 all other systems, these are never used anyway. [Reported by Mark Cox].
9512 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9514 Changes with Apache 0.8.5 01 Aug 1995
9516 *) Added last-minute configurable log experiment, as optional module
9518 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9519 properly. (One-line fix to http_protocol.c).
9521 *) Work around bogus behavior when reloading from Netscape.
9522 It's Netscape's bug --- for some reason they expect a request with
9523 If-modified-since: to not function as a conditional GET if it also
9524 comes with Pragma: no-cache, which is way out of line with the HTTP
9525 spec (according to Roy Fielding, the redactor).
9527 *) Added parameter to set maximum number of server processes.
9529 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9532 *) IdentityCheck bugfix [Chuck Murcko].
9534 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9536 *) More sample config file corrections; add extension to AddType for
9537 *.asis, move AddType generic description to its proper place, and
9538 fix miscellaneous typos. [ Alexei Kosut ]
9540 *) Deleted the *other* reference to the regents from the Berkeley
9541 legal disclaimer (everyplace).
9543 *) Nuked Shambhala name from src/README; had already cleaned it out
9546 Changes with Apache 0.8.4
9548 *) Changes to server-pool management parms --- renamed current
9549 StartServers to MinSpareServers, created separate StartServers
9550 parameter which means what it says, and renamed MaxServers to
9551 MaxSpareServers (though the old name still works, for NCSA 1.4
9552 back-compatibility). The old names were generally regarded as
9553 too confusing. Also altered "docs" in sample config files.
9555 *) More improvements to default config files ---
9556 sample directives (commented out) for XBitHack, BindAddress,
9557 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9558 defaults, AddTypes for send-as-is and imagemap magic types, and
9559 improvements to samples for DirectoryIndex [Alexei Kosut]
9561 *) Yet more improvements to default config files --- changes to
9562 Alexei's sample AddLanguage directives, and sample LanguagePriority
9563 [ Florent Guillaume ]
9565 *) Set config file locations properly if not set in httpd.conf
9568 *) Don't escape URIs in internal redirects multiple times; don't
9569 do that when translating PATH_INFO to PATH_TRANSLATED either.
9572 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9574 Changes with Apache 0.8.3
9576 *) Edited distribution README to *briefly* summarize installation
9577 procedures, and give a pointer to the INSTALL file in the src/
9580 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9581 recent NCSA distributions.
9583 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9584 exist for the same directory, use both and don't segfault. [Reported
9587 *) Proper makefile dependencies [David Robinson]
9589 *) Note (re)starts in error log --- reported by Rob Hartill.
9591 *) Only call no2slash() after get_path_info() has been done, to
9592 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9593 reported by Andrew Wilson, though this one is probably a real bug]
9595 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9596 dump core when Referer is not supplied. [Randy Terbush]
9598 *) Lightly edited sample config files to refer people to our documentation
9599 instead of NCSA's, and to list Rob McCool as *original* author (also
9600 deleted his old, and no doubt non-functional email address). Would be
9601 nice to have examples of new features...
9603 Changes with Apache 0.8.2 19 Jul 1995
9605 *) Added AddLanuage code [Florent Guillaume]
9607 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9609 *) All sorts of problems when MultiViews finds a directory. It would
9610 be nice if mod_dir.c was robust enough to handle that, but for now,
9611 just punt. [reported by Brian Behlendorf]
9613 *) Wait for all children on restart, to make sure that the old socket
9614 is gone and we can reopen it. [reported by Randy Terbush]
9616 *) Imagemap module is enabled in default Configuration
9618 *) RefererLog and UserAgentLog modules properly default the logfile
9621 *) Mark Cox's mod_cookies added to the distribution as an optional
9622 module (commented out in the default Configuration, and noted as
9623 an experiment, along with mod_dld). [Mark Cox]
9625 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9627 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9629 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9631 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9634 Changes with Apache 0.8.1
9636 *) New imagemap module [Randy Terbush]
9638 *) Replacement referer log module with NCSA-compatible RefererIgnore
9639 [Matthew Gray again]
9641 *) Don't mung directory listings with very long filenames.
9644 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9646 *) New config script. See INSTALL for info. [Robert Thau]
9648 *) Scoreboard mechanism for regulating the number of extant server
9649 processes. MaxServers and StartServers defaults are the same as
9650 for NCSA, but the meanings are slightly different. (Actually,
9651 I should probably lower the MaxServers default to 10).
9653 Before asking for a new connection, each server process checks
9654 the number of other servers which are also waiting for a
9655 connection. If there are more than MaxServers, it quietly dies
9656 off. Conversely, every second, the root, or caretaker, process
9657 looks to see how many servers are waiting for a new connection;
9658 if there are fewer than StartServers, it starts a new one. This
9659 does not depend on the number of server processes already extant.
9660 The accounting is arranged through a "scoreboard" file, named
9661 /tmp/htstatus.*, on which each process has an independent file
9662 descriptor (they need to seek without interference).
9664 The end effect is that MaxServers is the maximum number of
9665 servers on an *inactive* server machine, but more will be forked
9666 off to handle unusually heavy loads (or unusually slow clients);
9667 these will die off when they are no longer needed --- without
9668 reverting to the overhead of full forking operation. There is a
9669 hard maximum of 150 server processes compiled in, largely to
9670 avoid forking out of control and dragging the machine down.
9671 (This is arguably too high).
9673 In my server endurance tests, this mechanism did not appear to
9674 impose any significant overhead, even after I forced it to put the
9675 scoreboard file on a normal filesystem (which might have more
9676 overhead than tmpfs). [Robert Thau]
9678 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9681 *) Read .htaccess files even in directory with <Directory> section.
9682 (Former incompatibility noted on mailing list, now fixed). [Robert
9685 *) "HEAD /" gives the client a "Bad Request" error message, rather
9686 than trying to send no body *and* no headers. [Cliff Skolnick].
9688 *) Don't produce double error reports for some very obscure cases
9689 mainly involving auth configuration (the "all modules decline to
9690 handle" case which is a sure sign of a server bug in most cases,
9691 but also happens when authentication is badly misconfigured).
9694 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9695 it's *for*, and this sort of thing really shouldn't be cluttering
9696 up the Makefile). [Robert Thau]
9698 *) Incidental code cleanups in http_main.c --- stop dragging
9699 sa_client around; just declare it where used. [Robert Thau]
9701 *) Another acc-related fix. (It doesn't like const char
9702 in some places...). [Mark Cox]
9704 Changes with Shambhala 0.6.1 13 Jul 1995
9706 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9707 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9709 *) Compiles clean with acc on SunOS [Paul Sutton]
9711 *) Reordered modules in modules.c so that Redirect takes priority
9712 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9713 believe it or not, he has an actual site with a ScriptAlias and
9714 a Redirect declared for the *exact same directory*. Even *my*
9715 compatibility fetish wouldn't motivate me to fix this if the fix
9716 required any effort, but it doesn't, so what the hey.
9718 *) Fixed to properly default several server_rec fields for virtual
9719 servers from the corresponding fields in the main server_rec.
9720 [Cliff Skolnick --- 'port' was a particular irritant].
9722 *) No longer kills off nph- child processes before they are
9723 finished sending output. [Matthew Gray]
9725 Changes with Shambhala 0.6.0 10 Jul 1995
9727 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9728 the connection to the client in an "aborted" state, but otherwise
9729 allow whatever handlers are running to clean up. hard_timeout()s
9730 abort the request in progress completely; anything not tied to some
9731 resource pool cleanup will leak. They're still around because I
9732 haven't yet come up with a more elegant way of handling
9733 timeouts when talking to something that isn't the client. The
9734 default_handler and the dir_handler now use soft timeouts, largely
9735 so I can test the feature. [Robert Thau]
9737 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9738 the case of log handlers dying prematurely is probably handled VERY
9739 gracelessly at this point, and if the logger stops reading input,
9740 the server will hang. (It is known to correctly restart the
9741 logging process on server restart; this is (should be!) going through
9742 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9743 script). [Robert Thau]
9745 *) asis files supported (new module). [Robert Thau]
9747 *) IdentityCheck code is compiled in, but has not been tested. (I
9748 don't know anyone who runs identd). [Robert Thau]
9750 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9751 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9753 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9755 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9756 as timeouts are not in scope. [Robert Thau]
9758 *) quoted-string args in config files now handled correctly (doesn't drop
9759 the last character). [Robert Thau; reported by Randy Terbush]
9761 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9762 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9764 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9765 default default type); the former default default behavior when all
9766 type-checkers defaulted had been a core dump. [Paul Sutton]
9768 *) Copy filenames out of the struct dirent when indexing
9769 directories. (On Linux, readdir() returns a pointer to the same
9770 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9772 Changes with Shambhala 0.5.3 [not released]
9774 *) Default response handler notes "file not found" in the error log,
9775 if the file was not found. [Cliff Skolnick].
9777 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9778 code no longer sets up bogus PATH_INFO which fakes out the directory
9779 handler). [Cliff Skolnick]
9781 Changes with Shambhala 0.5.2 06 Jul 1995
9783 *) Changes to http_main.c --- root server no longer plays silly
9784 games with SIGCHLD, and so now detects and replaces dying
9785 children. Child processes just die on SIGTERM, without taking
9786 the whole process group with them. Potential problem --- if any
9787 child process refuses to die, we hang in restart.
9788 MaxRequestsPerChild may still not work, but it certainly works
9789 better than it did before this! [Robert Thau]
9791 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9792 work (or work better, at least); over-long description lines
9793 properly terminated. [Mark Cox]
9795 *) http_request.c now calls unescape_url() more places where it
9796 should [Paul Sutton].
9798 *) More directory handling bugs (reported by Cox)
9799 Parent Directory link is now set correctly. [Robert Thau]
9801 Changes with Shambhala 0.5.1 04 Jul 1995
9803 *) Generalized cleanup interface in alloc.c --- any function can be
9804 registered with alloc.c as a cleanup for a resource pool;
9805 tracking of files and file descriptors has been reimplemented in
9806 terms of this interface, so I can give it some sort of a test.
9809 *) More changes in alloc.c --- new cleanup_for_exec() function,
9810 which tracks down and closes all file descriptors which have been
9811 registered with the alloc.c machinery before the server exec()s a
9812 child process for CGI or <!--#exec-->. CGI children now get
9813 started with exactly three file descriptors open. Hopefully,
9814 this cures the problem Rob H. was having with overly persistent
9815 CGI connections. [Robert Thau]
9817 *) Mutual exclusion around the accept() in child_main() --- this is
9818 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9819 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9820 This uses fcntl(F_SETLK,...) on the error log descriptor because
9821 flock() on that descriptor won't work on systems which have BSD
9822 flock() semantics, including (I think) Linux 1.3 and Solaris.
9824 This does work on SunOS (when the server is idle, only one
9825 process in the pool is waiting on accept()); it *ought* to work
9826 on the other systems. [Robert Thau]
9828 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9830 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9832 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9834 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9835 be unnecessary if I go to the revised timeout-handling scheme).
9838 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9839 string) even if none came in with the request. [Robert Thau]
9841 *) CHANGES file added to distribution ;-).
9843 Changes with Shambhala 0.4.5
9845 *) mod_dld --- early dynamic loading support [rst]
9846 *) Add wildcard content handlers for XBITHACK; default_hander now
9847 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9848 *) XBITHACK supported as a wildcard content-handler, and
9849 configurable at run-time (not just at compile time, as in the
9850 "patchy server" releases) [rst]
9852 Changes with Shambhala 0.4.4 30 Jun 1995
9854 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9855 *) Handle Addtype x/y .z [rst, reported by Cox]
9857 Changes with Shambhala 0.4.3
9859 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9860 synonymous [rst, terbush]
9862 Changes with Shambhala 0.4.1 28 Jun 1995
9864 *) First-cut virtual host implementation; some refit in the config
9865 reading code, and log management, was necessary to support this [rst]
9866 *) Sub-pool machinery, originally added to avoid excessive storage
9867 allocation on listings of large directories (which turned out to
9868 be the problem that the 0.3 storage accounting was added to
9869 find). Subrequests and mod_dir changed to use subpools. [rst]
9870 *) More memory debugging --- free list consistency checks. [rst]
9871 *) Added err_headers to request_rec, with support elsewhere [rst]
9872 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9874 Changes with Shambhala 0.3 19 Jun 1995
9876 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9877 *) Don't compile in mod_ai_backcompat by default
9878 *) Switch name of server from Apache to Shambhala in Makefile
9879 *) Add some accounting routines to track memory usage in the pools,
9882 Changes with Shambhala 0.2
9884 *) Set DOCUMENT_ROOT CGI variable
9885 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9886 *) Add critical section protection to handling of cleanup structures
9888 *) Significant code reorg within the server core to group related
9889 functions together [rst]
9890 *) Correctly handle clients that hang up before sending any request
9892 *) Replace dying child processes. [rst]
9894 Changes with Shambhala 0.1 12 Jun 1995
9896 Major rewrite of the pre-existing "patchy server" codebase, by
9897 Robert Thau (rst). Significant portions of the server code, such
9898 as configuration-file handling and HTTP authentication support,
9899 were ripped out and rewritten from scratch. Code that was not
9900 completely rewritten was significantly altered.
9902 Major changes with this release include:
9904 *) Introduction of the module API; in request handling, the central
9905 machinery just dispatches to various modules, which actually do
9906 most of the work. Configuration handling is similar --- modules
9907 declare their own commands, and the central machinery just
9910 API features from shambhala/0.1 were substantially unchanged in
9911 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9912 release, such as wildcard handlers and subpools, were added in
9913 subsequent Shambhala releases, and were also generally rst's
9916 *) This release included the following modules:
9918 mod_access (access control --- allow and deny directives),
9919 mod_alias (Alias and Redirect commands),
9920 mod_auth (straight HTTP authentication, based on flat-files)
9921 mod_auth_dbm (same, with dbm files)
9922 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9923 mod_common_log (CLF access logs; later renamed mod_log_common)
9924 mod_dir (directory indexing)
9925 mod_include (server-side includes)
9926 mod_mime (AddType directives)
9927 mod_negotiation (content negotiation)
9928 mod_userdir (support for users' public_html directories)
9930 It also included a mod_ai_backcompat, which was a private hack
9931 for back-compatibility with rst's own AI-lab servers.
9933 All of these modules were substantially complete, and functional
9934 or nearly so (a few, which implemented features not in use at
9935 Thau's site, required patches of a few lines).
9937 *) sub-request machinery, to allow modules to determine how other
9938 modules would assign MIME types to a given file, or optionally
9939 serve its content (this is heavily used by mod_dir, mod_include
9940 and mod_negotiation).
9942 *) Resource pool system for keeping track of memory allocated and
9943 files opened in service of a particular request. Much of the
9944 code in the modules (when they weren't rewrites) was adjusted to
9945 replace a pervasive convention of using fixed-size buffers on
9946 the stack with an equally pervasive convention of using memory
9947 allocated with palloc().
9949 *) Reorganization of data structures associated with a given
9950 request to eliminate use of global variables and the troublesome
9951 unmunge_name function (used in NCSA and early Apache releases to
9952 attempt to determine the URI which mapped to a given filename
9953 --- a difficult proposition, given that it is easy to produce
9954 setups in which multiple URIs map to the same file).
9956 *) Source files renamed and rearranged
9958 *) Very simple pre-forking behavior --- parent process forked off a
9959 fixed number of children, and then just waited for SIGHUP.
9961 *) Other more minor changes too numerous to list.
9963 This release included modified versions of a lot of code from the
9964 Apache 0.6.4 public release, plus an early pre-forking patch
9965 codeveloped by Robert Thau and Rob Hartill.
9967 Changes with Apache 0.7.3 20 Jun 1995
9969 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9970 were incorporated by Rob Hartill on the main branch while Robert Thau
9971 worked on the Shambhala rewrite above. Most were merged into the
9972 Shambala architecture after Apache 0.8.0.
9974 Changes with Apache 0.6.4 13 May 1995
9976 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
9979 Changes with Apache 0.5.1 10 Apr 1995
9981 Changes with Apache 0.4 02 Apr 1995
9983 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
9986 Changes with Apache 0.3 24 Mar 1995
9988 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
9991 Changes with Apache 0.2 18 Mar 1995
9993 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
9994 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
9995 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
