1 Changes with Apache 2.0.25-dev
3 *) Fix a minor issue with Jeff Trawick's mod_include
4 patch. Without this patch, the code will just allocate
5 more bytes in get_combined_directive than are needed.
7 *) Added the LDAP authentication module mod_auth_ldap.
8 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
10 *) Added the LDAP cache and connection pooling module mod_ldap.
11 [Dave Carrigan <dave@rudedog.org>, Graham Leggett]
13 *) Fix --enable-modules=all breakage with mod_auth_db and mod_auth_digest
14 by allowing a module to disable itself if its prerequisites are not
15 met. [Justin Erenkrantz]
17 Changes with Apache 2.0.24
19 *) Fix a couple of issues in mod_include when the tag appeared at
20 offsets near 8192 in the file being parsed. [Jeff Trawick]
22 *) Fix an assertion failure in mod_ssl when the keepalive timeout is
23 reached. [Jeff Trawick]
25 *) Numerous improvements to the Win32 build system. Introduced command line
26 builds without requiring .mak files for MSVC 6.0 and later versions.
27 Improved .dsp file compatibility for both Visual Studio 5.0 and 6.0 users.
30 *) Assorted corrections and improvements to the winnt_mpm startup code. Better
31 reporting of uninstalled services and other error conditions, and changed the
32 default service name to Apache2. [William Rowe]
34 *) Numerous improvements to the Win32 ApacheMonitor utility, including winnt_mpm
35 compatibility with existing Apache 1.3 Win32 Apache management utilites.
36 [Mladen Turk <mturk@mappingsoft.com>, William Rowe]
38 *) Fixed the segfaults in mod_mime introduced by hash tables in 2.0.20.
39 [William Rowe, Greg Ames]
41 *) Rounded out the mod_mime Add/Remove pairs by adding RemoveLanguage
42 and RemoveCharset directives. [William Rowe]
44 *) The Unix MPMs other than perchild now allow child server
45 processes to use the accept mutex when starting as root and
46 using SysV sems for the accept mutex. Previously, this
47 combination would lead to fatal errors in the child server
48 processes. perchild can't use SysV sems because of security
49 issues. [Jeff Trawick, Greg Ames]
51 *) Added Win32 revision stamp resources to all http binaries
52 (including modules/ and support/ tools.) PR7322 [William Rowe]
54 *) Fix ap_rvprintf to support more than 4K of data at one time.
55 [Cody Sherr <csherr@covalent.net>]
57 *) We have always used the obsolete/deprecated Netscape syntax
58 for our tracking cookies; now the CookieStyle directive
59 allows the Webmaster to choose the Netscape, RFC2109, or
60 RFC2965 format. The new CookieDomain directive allows the
61 setting of the cookie's Domain= attribute, too. PR #s 5006,
62 5023, 5920, 6140 [Ken Coar]
64 *) Tweak server/Makefile so that the rules for generating exports.c
65 are compatible with make utilities which don't expand wildcards
66 in a dependency list (e.g., OS/390 make, certain levels of GNU
69 *) Install the SSL headers. [John Sterling <sterling@covalent.net>]
71 *) Begin to sanitize the MPM configuration directives. Now, all
72 MPMs use the same functions for all common MPM directives. This
73 should make it easier to catch all bugs in these directives once.
74 [Cody Sherr <csherr@covalent.net>]
76 *) Close a major resource leak. Every time we had issued a
77 graceful restart, we leaked a socket descriptor.
80 *) Fix a problem with the new method code. We need to cast
81 the 1 to an apr_int64_t or it will be treated as a 32-bit
82 integer, and it will wrap after being shifted 32 times.
83 [Cody Sherr <csherr@covalent.net> and Ryan Morgan <rmorgan@covalent.net>]
85 *) Fix a bug in mod_expires. Previous to this patch, if you
86 told mod_expires to add 604800 seconds to the last-modified
87 time, it actually added 604800 usec's to the last-modified time,
88 so that when looking at the response it looked like nothing
89 had been done. The root of the problem was that we always compute
90 time in usec's, but we ask users to input sec's. This means we
91 need to convert to usec's before using those values.
94 *) The worker MPM now handles shutdown and restart requests. It
95 definitely isn't perfect, but we do stop the servers correctly.
96 The biggest problem right now is that SIGHUP causes the server to
97 just die. [Ryan Bloom]
99 Changes with Apache 2.0.23
101 *) Use the prefork MPM by default on Unix. [various]
103 *) Added a systray icon monitor application for Win32.
104 [Mladen Turk <mturk@mappingsoft.com>]
106 *) mod_rewrite: Fix the line ending on some non-Unix systems for
107 messages written to the rewrite log.
108 [Richard Labennett <rlabenn@us.ibm.com>]
110 *) All mod_autoindex query parsing is now quietly quashed with the
111 IndexOption IgnoreClient. The IndexOption SuppressColumnSorting
112 still drops the column sort <a href>'s for the column headers, but
113 IgnoreClient is required to ignore these Query options entirely.
116 *) Introduced new mod_autoindex query argument parsing for F=[0|1|2]
117 to allow the client to select plain, FancyIndexing or HTMLTable
118 formatting, V=[0|1] to inhibit or enable version sorting, and
119 P=pattern to return only specific files. The old Query Arguments
120 were reorganized as C=f for sorting column 'f' (same N, D, S, or M
121 as before), and O=A|D for ordering ascending or descending.
124 *) Fixed an error in mod_include's directive parsing routines which
125 caused #if, #elif, and #else expressions containing backslashes
126 to be improperly evaluated. [Cliff Woolley]
128 *) Introduced new mod_autoindex IndexOptions flags: SuppressIcon to
129 drop the icon column, SuppressRules to drop the <hr> elements,
130 and HTMLTable to create rudimentary HTML table listings (implies
131 FancyIndexing). [William Rowe]
133 *) Re-introduced the mod_autoindex IndexOptions flag TrackModified
134 from Apache 1.3.15. This is needed for two reasons, first, given
135 multiple machines within a server farm, ETags and Last-Modified
136 stamps won't correspond from machine to machine, and second, many
137 Unixes don't capture changes to the date or time stamp of existing
138 files, since these don't modify the dirent itself. [William Rowe]
140 *) Re-introduced the mod_autoindex IndexOptions flag FoldersFirst
141 and DirectoryWidth options from Apache 1.3.10.
142 [William Rowe, Ken Coar]
144 *) Eliminated FancyIndexing directive, deprecated early in Apache
145 1.3 by the IndexOptions FancyIndexing syntax. [William Rowe]
147 *) mod_autoindex now excludes any file names that would result in
148 an error, other than a success or redirect. Also optimized
149 the parent directory, always included except in the URI '/'.
152 *) Refactored mod_negotiation and mod_mime to help mod_dir accept
153 negotiated index pages, and prevent the server from defaulting
154 to an autoindex of the directory. mod_negotiation will now die
155 with a 500 Internal Error if it could match some filenames
156 (e.g. for mod_dir) but none can be served. mod_negotation now
157 refuses to serve any file with an extention that mod_mime doesn't
158 recognize, and wasn't part of the request. [William Rowe]
160 *) Eliminate mod_cgi's handling of .exe files without the .exe file
161 extension. This is already handled by multiviews, if the admin
162 wishes to AddHandler .exe or define a content type handler and
163 associate .exe files with that content type. Multiviews must be
164 enabled to allow these to be served. [William Rowe]
166 *) Speed up the server's response to a spike in incoming workload
167 or restarts by assigning empty scoreboard slots to new processes
168 when they are available. [Greg Ames]
170 *) Add a handler to mod_includes.c. This handler is designed to
171 implement the XbitHack directive. This can't be done with a
172 fixup, because we need to check the content-type, which is
173 only available in the handler phase. [Ryan Bloom]
175 *) Make the includes filter check return codes from filters lower in
176 the filter chain. If a lower level filter returns an error, then
177 the request needs to stop immediately. This allows mod_include to
178 stop parsing data once a lower filter recognizes an error.
181 *) Add the ability to extend the methods that Apache understands
182 and have those methods <limit>able in the httpd.conf. It uses
183 the same bit mask/shifted offset as the original HTTP methods
184 such as M_GET or M_POST, but expands the total bits from an int to
185 an ap_int64_t to handle more bits for new request methods than
186 an int provides. [Cody Sherr <csherr@covalent.net>]
188 *) Fix broken mod_mime behavior in merging its arguments. Possible
189 cause of unexplicable crashes introduced in 2.0.20. [William Rowe]
191 *) Solve many mod_ssl porting issues (too many to detail) with
192 help from the whole team, but most notably [Ralf S. Engelschall,
193 Madhusudan Mathihalli <madhusudan_mathihalli@hp.com>,
194 Doug MacEachern, William Rowe, Cliff Woolley]
196 *) More stall fixes for the threaded & worker mpm's.
197 Make mod_status output more accurate. Don't
198 count workers in processes which aren't actively
199 serving requests. [Greg Ames]
201 *) Win32: Get SSI exec cgi tag working. [Bill Stoddard]
203 *) Add a single listener/multiple worker MPM. This MPM is
204 definately not fully correct, but it allows us to solve many
205 of the problems that exist in the threaded MPM. This is a
206 modified version of the threaded MPM. [Ryan Bloom]
208 *) Improve content generation throughout Apache, providing closer
209 compliance with HTML 3.2, HTML 4.01 Transitional and XHTML 1.0
210 Transitional specifications. [William Rowe]
212 Changes with Apache 2.0.22
214 *) Fix a problem where the threaded MPM stalls after restarts or
215 segfaults. Also prevent multiple active processes from using
216 the same scoreboard slot. [Greg Ames]
218 *) Apache/Win32 now fills in the service description with Apache's
219 server version string, including loaded and advertised modules.
222 *) Improved support for the Win32 build, to recover gracefully from
223 missing apr or apr-util directories or the awk interpreter,
224 create the proper cgi-bin examples, including a test-cgi.bat, and
225 fix the perl shebang line for printenv.pl, when installing from
226 the build environment. [William Rowe]
228 *) Fix a segfault in threaded.c caused by passing uninitialized
229 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
231 *) Use new APR number conversion functions to reduce CPU consumption
232 when setting the content length, and in mod_log_config.
235 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
236 where HEAD response headers were being repeated twice for
237 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
238 problem in the http_header filter was exposed by the recent rewrite
239 of the content_length filter. [Taketo Kabe, Bill Stoddard]
241 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
242 restarts. A garbage pointer to a vhost's server_rec from the
243 previous generation was being left around under certain
244 conditions. [Greg Ames]
246 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
247 used to appear as '(none', without the closing paren.
248 [Günter Knauf <eflash@gmx.net>]
250 *) Improve the exports generating awk script. In the past, we had
251 work around problems in the awk script by avoiding some #if and
252 #ifdefs. This has bitten us many times in generating the exports.c
253 file. This improvement allows corrects the header file parsing.
254 [Sander Striker <striker@apache.org>]
256 Changes with Apache 2.0.21
258 *) Resolve the Win32 htpasswd bug, where a file that existed would be
259 overwritten, regardless of the -c flag.
260 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
262 *) Introduce connection sub-pools into ab. Truncating the lifetime
263 of these allocations means that ab no longer perpetually grows
264 its working set, running out of memory on large request attempts.
267 *) Make scoreboard creation a hook. This allows management
268 modules to have access to the scoreboard at the time that it is
269 created, and at every restart request.
270 [Cody Sherr <csherr@covalent.net>]
272 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
273 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
274 daemon index actually used in the scoreboard. I also
275 updated the pertinent calls. [Paul J. Reder]
277 *) Win32: Prevent listening sockets from being inherited by
278 the Apache child process, CGI scripts, rotatelog process
279 etc. If the Apache child process segfaults, any processes
280 that the child started are not reaped. Prior to this fix,
281 these processes inherited the listening sockets which sometimes
282 prevented the restarted Apache child process from accepting
283 connections (ie, the server would hang).
286 *) Provide vhost and request strings when ExtendedStatus is on.
289 *) Fix some issues with the pod and prefork: check the pod *after*
290 processing a connection so that a server processing a time-
291 consuming request bails out as soon as practical; when the
292 parent process wakes up a server process via connect(), use an
293 APR timeout on the connect() so that we don't hang for a long
294 time if there aren't server processes around to do accept().
295 [Jeff Trawick, Greg Ames]
297 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
298 spends a lot of time in apr_table_get calls. Using the default
299 httpd.conf, the tables for languages and charsets are somewhat
300 large, so the time spent scanning them on each request is
301 significant. Replacing the tables with hash tables provides
302 a nice speedup. [Brian Pane <bpane@pacbell.net>]
304 *) Add two functions to allow modules to access random parts of the
305 scoreboard. This allows modules compiled for one MPM to access the
306 scoreboard, even if it the server was compiled for another MPM.
307 [Harrie Hazewinkel <harrie@covalent.net>]
309 Changes with Apache 2.0.20
311 *) Fix problem in content-length filter where the filter would
312 buffer all the output from a CGI before sending any bytes
313 down the filter stack to the network. This problem would cause
314 significant memory consumption if the CGIs generated
315 lots of bytes. [Bill Stoddard]
317 *) Get non-blocking CGI pipe reads working with the bucket brigades.
320 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
323 *) Fix a bug in the threaded MPM that would cause it to kill off all
324 workers immediately after starting if the number of workers started
325 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
327 Changes with Apache 2.0.19
329 *) Fix problem with threaded MPM. The problem was that if each child
330 process was busy serving a single long-lived request and the server
331 was sent a graceful restart signal, the server would stop serving
332 requests. This would happen because each child process would wait to
333 die until the last thread was done, and the parent wouldn't spawn any
334 new children until a process died. Now, the parent looks at the fact
335 that the children are dying gracefully, and starts new children.
336 Those new children only start enough threads to compliment the number
337 of threads in the other child process that shares the same spot in
338 the scoreboard. In this way, we make sure to never go over
339 MaxClients. [Ryan Bloom]
341 *) modified mod_negotiation and mod_autoindex to speed up by almost a
342 factor of two on apr_dir_read()-enhanced platforms, such as Win32
343 and OS2, by calling ap_sub_request_lookup_dirent() with the results
344 already provided by apr_dir_read(). [William Rowe]
346 *) mod_file_cache is now more robust to filtering and serves requests
347 slightly more efficiently. [Cliff Woolley]
349 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
350 Module was calling ap_rwrite() followed by ap_rflush() but the
351 served content was not being displayed in the browser. Inspection
352 of the output stream revealed that the first data chunk was
353 missing the trailing CRLF required by the RFC. [Bill Stoddard]
355 *) apxs no longer generates ap_send_http_header() in the example handler
357 *) Fix an ab problem which could cause a divide-by-zero exception
358 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
359 [Ian Holsman <ianh@cnet.com>]
361 *) Solve case-insensitive platforms' confusion about negotiated
362 filenames, allowing files of differnt case to match in choosing
363 the document to serve. [William Rowe]
365 *) Fix brokenness when ThreadsPerChild is higher than the built-in
366 limit. We left ap_threads_per_child at the higher value which
367 led to segfaults when doing certain scoreboard operations.
370 *) Fix seg faults and/or missing output from mod_include. The
371 default_handler was using the subrequest pool for files and
372 MMAPs, even though the associated APR structures typically
373 live longer than the subrequest. [Greg Ames]
375 *) Extend mod_setenvif to support specifying regular expressions
376 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
377 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
378 will cause HAVE_TS to be set if any of the request headers begins
379 with "TS" and has a value that begins with any character in the
380 set [a-z]. [Bill Stoddard]
382 *) httpd children now re-bind themselves to a random CPU on
383 multiprocessor systems on AIX via bindprocessor() in 2.0.
384 [Victor J. Orlikowski]
386 *) Fix htdigest. It would go into a loop in getline when adding
387 a second user. [Bill Stoddard]
389 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
391 *) Automatically generate httpd.exp for AIX.
392 DSOs now work again on AIX in 2.0
393 [Victor J. Orlikowski]
395 *) Add a new request hook, error_log. This phase allows modules
396 to act on the error log string _after_ it has been written
397 to the error log. The goal for this hook is to allow monitoring
398 modules to send the error string to the monitoring agent.
401 *) Modify mod_echo to make it use filters for input and output.
402 [Ryan Morgan <rmorgan@covalent.net>]
404 *) Extend mod_headers to support conditional driven Header
405 add, append and set. Use SetEnvIf to set an envar and conditionally
406 add/append/set headers based on this envar thusly:
408 SetEnvIf TSMyHeader value HAVE_TSMyHeader
409 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
411 If the request contains header "TSMyHeader: value" then header
412 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
415 *) Extend mod_headers to support using format specifiers on Header
416 add, append and set header values. Two format specifiers are supported:
418 %t - reports, in UTC microseconds since the epoch, when the
419 request was received.
421 %D - reports the time, in microseconds, between when the request was
422 received and the response sent.
425 Header add MyHeader "This request served in %D microseconds. %t"
427 results in a header being added to the response that looks like this:
429 MyHeader: This request served in D=5438 microseconds. t=991424704447256
433 *) Fix reset_filter(). We need to be careful how we remove filters.
434 If we set r->output_filters to NULL, we also have to reset the
435 connection's filters. [John Sterling]
437 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
439 *) Add a check to ap_die() to make sure the filter stack is sane and
440 contains the correct basic filters when an error occurs. This fixes
441 a problem where headers are not being sent on error. [John Sterling]
443 *) New Header directive 'echo' option. "Header echo regex" will
444 cause any headers received on the request that match regex to be
445 echoed to (included in) the response headers.
448 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
449 This prevented the inclusion of apr_compat.h. PR #7773
450 [Oleg Broytmann <phd@phd.pp.ru>]
452 *) Moved util_uri to the apr-util library. This required a bunch of
453 apr_name changes for the uri utility functions. [Justin Erenkrantz]
455 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
456 insert_filter phase so that other filters are not bypassed by default.
459 *) Reimplement mod_headers as an output filter. mod_headers can now
460 add custom headers to inbound requests using the RequestHeader directive
461 and to responses using the same old Header directive. [Graham Leggett]
463 Changes with Apache 2.0.18
465 *) Fix command-line processing so that if a bad argument is specified
466 Apache will exit. [Jeff Trawick]
468 *) Change the make targets and rules to be consistent in all of the
469 Apache-owned source trees. [Roy Fielding]
471 *) Fix processing of the TRACE method. Previously we passed bogus
472 parms to form_header_field() and it overlaid some vhost structures,
473 resulting in a segfault in check_hostalias().
474 [Greg Ames, Jeff Trawick]
476 *) Win32: Add support for reliable piped logs. If the logging process
477 goes down, Apache will automatically restart it. This function has
478 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
481 *) Do not start piped log processes during the config file
482 preflight. This change also circumvents a problem on
483 Windows where the rotatelog processes created during preflight
484 was not getting cleaned up properly.
487 *) add "Request Phase Participation" info to mod_info
490 *) Make first phase changes to the scoreboard data structures in
491 preparation for the rewriting of the scoreboard per my posted
492 design notes. [Paul J. Reder]
494 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
495 and apr-util, allow it to be overridden by the configure command-line
496 (default="--silent") and introduce LT_LDFLAGS to replace what we were
497 formerly abusing as LTFLAGS. [Roy Fielding]
499 *) Clean up the reporting of incorrect closing container tags.
500 [Barrie Slaymaker <barries@slaysys.com>]
502 *) Simplify the configure process by moving all libtool stuff to APR
503 and moving hints.m4 inline. [Roy Fielding]
505 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
506 of functions used by mod_proxy for export in the DLL
507 [Ian Holsman <IanH@cnet.com>]
509 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
510 request body from its stdin but no reqest body is being written to
511 the cgi. [Jeff Trawick]
513 *) mod_log_config: %c connection status incorrectly logged
514 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
517 *) Get mod_cern_meta working under Windows
520 *) Create Files, and thus MMAPs, out of the request pool, not the
521 connection pool. This solves a small resource leak that had us
522 not closing files until a connection was closed. In order to do
523 this, at the end of the core_output_filter, we loop through the
524 brigade and convert any data we have into a single HEAP bucket
525 that we know will survive clearing the request_rec.
526 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
529 *) Completely revamp configure so that it preserves the standard make
530 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
531 the configure additions to EXTRA_* variables. Also, allow the user
532 to specify NOTEST_* values for all of the above, which eliminates the
533 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
534 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
535 avoid pointless duplications. Fix the order in which flags are given
536 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
537 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
538 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
539 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
541 *) Get mod_tls to compile/work better on Windows. PR #7612
542 [Bernhard Schrenk <b.schrenk@improx.com>]
544 *) Fix shutdown/restart hangs in the threaded MPM.
545 [Jeff Trawick, Greg Ames, Ryan Bloom]
547 *) Removed the keptalive boolean from conn_rec because it is now only
548 used by a single routine and can be replaced by a local variable.
549 [Greg Stein, Ryan Bloom, Roy Fielding]
551 *) Patch prefork to put enough of the signal processing back in so that
552 signals are all handled properly now. The previous patch fixed the
553 deadlock race condition, but broke the user directed signal handling.
554 This fixes it to work the way it did before my previous prefork patch
555 (primarily, SIGTERM is now working).
557 *) Change how input filters decide how much data is returned to the
558 higher filter. We used to use a field in the conn_rec, with this
559 change, we use an argument to ap_get_brigade to determine how much
560 data is retrieved. [Ryan Bloom]
562 *) Fix seg fault at start-up introduced by Ryan's change to enable
563 modules to specify their own logging tags. mod_log_config
564 registers an optional function, ap_register_log_handler().
565 ap_register_log_handler() was being called by http_core before
566 the directive hash table was created. This patch creates the
567 directive hash table before ap_register_log_handler() is
568 registered as an optional function.
569 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
571 *) Add ap_set_int_slot() function
572 [John K. Sterling <sterling@covalent.net>]
574 *) Under certain circumstances, Apache did not supply the
575 right response headers when requiring authentication.
576 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
577 (This is a port of the change that went into Apache 1.3.19.)
579 *) Allow modules to specify their own logging tags. This basically
580 allows a module to tell mod_log_config that when %x is encountered
581 a specific function should be called. Currently, x can be any single
582 character. It may be more useful to make this a string at some point.
585 Changes with Apache 2.0.17
587 *) If a higher-level filter handles the the byterange aspects of a
588 request, then the byterange filter should not try to redo the
589 work. The most common case of this happening, is a byterange
590 request going through the proxy, and the origin server handles
591 the byterange request. The proxy should ignore it.
592 [Graham Leggett <minfrin@sharp.fm>]
594 *) Changed the threaded mpm to have child_main join to each of the
595 worker threads to make sure the kids are all gone before child_main
596 exits after a signal (cleanup from perform_idle_server_maintenance).
597 This is an extension of Ryans recent commit to make the child_main
600 *) Add more options to the ap_mpm_query function. This also allows MPMs to
601 report if their threads are dynamic or static. Finally, this also
602 implements a new API, ap_show_mpm, which returns the MPM that was
603 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
605 *) Do not install the binaries from the support directory twice.
606 [jun-ichiro hagino <itojun@iijlab.net>]
608 *) The ap_f* functions should flush data to the filter that is passed
609 in, not the the filter after the one passed in.
610 [Ryan Morgan <rmorgan@covalent.net>]
612 *) Make ab work again by changing its native types to apr types and formats.
613 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
615 *) Move the byterange filter and all of the supporting functions back
616 to the HTTP module. The byterange filter turned out to be very
617 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
619 *) Make clean, distclean, and extraclean consistently according to the
620 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
622 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
623 This may have been causing problems stopping processes in the threaded
626 *) Fix content-length in mod_negotiation to a long int representation.
629 *) Remove BindAddress from the default config file.
630 [giles@nemeton.com.au]
632 *) Allow module authors to add a module to their Apache build using
633 --with-module, without re-running buildconf. The syntax is:
634 --with-module=module_type:/path/to/module.c
635 The configure script will copy the module.c file to
636 modules/module_type, and it will be added to the relevant Makefiles.
637 currently, this only works for static modules. [Ryan Bloom]
639 *) Changes required to make prefork clean up idle children properly.
640 There was a window during which a starting worker deadlocks when
641 an idle cleanup arrives before it completes init. Apache then keeps
642 trying to cleanup the same deadlocked worker forever (until higher
643 pids come along, but it still will never reduce below the deadlocked
644 pid). Thus the number of children would not reduce to the correct
645 idle level. [Paul J. Reder]
647 Changes with Apache 2.0.16
649 *) Change the default installation directory to /usr/local/apache2,
650 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
652 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
655 *) Get MaxRequestsPerChild working with the Windows MPM.
658 *) Make generic hooks to work, with mod_generic_hook_import/export
659 experimental modules. [Ben Laurie, Will Rowe]
661 *) Fix segfaults for configuration file syntax errors such as
662 "<Directory>" followed by "</Directory" and
663 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
665 *) Cleanup the --enable-layout option of configure. This makes
666 us use a consistent location for the config.layout file, and it
667 makes configure more portable.
668 [jun-ichiro hagino <itojun@iijlab.net>]
670 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
671 csv/gnuplot format, rudimentary ssl support and various other tweaks
672 to make results more true to what is measured. The upshot of this it
673 turns out that 'ab' has often underreported the true performance of
674 apache. Often by a order of magnitude :-) See talk/paper of Sander
675 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
676 [Dirk-Willem van Gulik]
678 *) Clean up mod_cgid's temporary request pool. Besides fixing a
679 storage leak this ensures that some unnecessary pipes are closed.
682 *) Performance: Add quick_handler hook. This hook is called at the
683 very beginning of the request processing before location_walk,
684 translate_name, etc. This hook is useful for URI keyed content
685 caches like Mike Abbott's Quick Shortcut Cache.
688 *) top_module global variable renamed to ap_top_module [Perl]
690 *) Move ap_set_last_modified to the core. This is a potentially
691 controversial change, because this is kind of HTTP specific. However
692 many protocols should be able to take advantage of this kind of
693 information. I expect that headers will need one more layer of
694 indirection for multi-protocol work, but this is a small step in
695 the right direction. [Ryan Bloom]
697 *) Enable mod_status by default. This matches what Apache 1.3 does.
700 *) Add a ScriptSock directive to the default config file. This is
701 only enabled when mod_cgid is used.
702 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
704 Changes with Apache 2.0.15
706 *) Untangled the buildconf script and eliminated the need for build's
707 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
708 libtool muck that is now under srclib/apr/build. [Roy Fielding]
710 *) Win32: Don't accept more connections than we have worker threads
714 *) Fix bug in the Unix threaded.c MPM that allowed child processes
715 to fork() new child processes.
718 *) Fix a major security problem with double-reverse lookup checking.
719 Previously, a client connecting over IPv4 would not be matched
720 properly when the server had an IPv6 listening socket. PR #7407
721 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
723 *) Change the way the beos MPM handles polling to allow it to stop and
724 restart. Problem was the sockets being polled were being reset by
725 the select call, so once it had accepted a connection it was no
726 longer listening on the UDP socket we use for shutdown instructions.
727 APR needs to be altered, patch on it's way. [David Reid]
729 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
730 on error exit from ap_getline(). Some other code got upset because
731 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
733 *) Handle ap_discard_request_body() being called more than once.
734 [Greg Ames, Jeff Trawick]
736 *) Get rid of an inadvertent close of file descriptor 2 in
737 mod_mime_magic. [Greg Ames, Jeff Trawick]
739 *) Add a hook, create_request. This hook allows modules to modify
740 a request while it is being created. This hook is called for all
741 request_rec's, main request, sub request, and internal redirect.
742 When this hook is called, the the r->main, r->prev, r->next
743 pointers have been set, so modules can determine what kind of
744 request this is. [Ryan Bloom]
746 *) Cleanup the build process a bit more. The Apache configure
747 script no longer creates its own helper scripts, it just
749 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
751 *) Stop the forced downgrade of the connection to HTTP/1.0 for
752 proxy requests. [Graham Leggett]
754 *) Avoid using sscanf to determine the HTTP protocol number in
755 the common case because sscanf is a performance hog. From
756 Mike Abbot's Accelerating Apache patch number 6.
757 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
759 *) Fix a security exposure in mod_access. Previously when IPv6
760 listening sockets were used, allow/deny-from-IPv4-address rules
761 were not evaluated properly (PR #7407). Also, add the ability to
762 specify IPv6 address strings with optional prefix length on Allow
763 and Deny. [Jeff Trawick]
765 *) Enhance rotatelogs so that a UTC offset can be specified, and
766 the logfile name can be formatted using strftime(3). (Brought
767 forward from 1.3.) [Ken Coar]
769 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
770 DuplicateHandle on an IOCompletionPort (a practice which
771 MS "discourages"). The new model does not rely on associating
772 the completion port with the listening sockets, thus the
773 completion port can be completely managed within the child
774 process. A dedicated thread accepts connections off the network,
775 then calls PostQueuedCompletionStatus() to wake up worker
776 threads blocked on the completion port.
779 *) Bring forward the --suexec-umask option which allows the
780 builder to preset the umask for suexec processes. [Ken Coar]
782 *) Add a -V flag to suexec, which causes it to display the
783 compile-time settings with which it was built. (Only
784 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
786 *) Mod_include should always unset the content-length if the file is
787 going to be passed through send_parsed_content. There is no to
788 determine if the content will change before actually scanning the
789 entire content. It is far safer to just remove the C-L as long
790 as we are scanning it. [Ryan Bloom]
792 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
793 request and not Proxy-Authenticate.
794 [Graham Leggett <minfrin@sharp.fm>]
796 Changes with Apache 2.0.14
798 *) Fix content-length computation. We ONLY compute a content-length if
799 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
800 or we already have all the data. [Ryan Bloom]
802 *) Report unbounded containers in the config file. Previously, a typo
803 in the </container> directive could result in the rest of the config
804 file being silently ignored, with undesired defaults used.
807 *) Make the old_write filter use the ap_f* functions for the buffering.
810 *) Move more code from the http module into the core server. This
811 is core code, basically the default handler, the default input
812 and output filters, and all of the core configuration directives.
813 All of this code is required in order for the server to work, with or
814 without HTTP. The server is closer to working without the HTTP
815 module, although there is still more to do. [Ryan Bloom]
817 *) Fix a number of SGI compile warnings throughout the server. Fix some
818 bad parameters to apr_bucket_read(). Fix a bad statement in
819 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
820 consistently; we were mixing apr_time_t and time_t in invalid ways
821 before. In load_file(), call apr_dso_error() instead of
822 apr_strerror() so that we get a more specific string on some platforms.
823 PR #6980 [Jeff Trawick]
825 *) Allow modules to query the MPM about it's execution profile. This
826 query API can and should be extended in the future, but for now,
827 max_daemons, and threading or forking is a very good start.
828 [Jon Travis <jtravis@covalent.net>]
830 *) Modify mod_include to send blocks of data no larger than 9k.
831 Without this, mod_include will wait until the whole file is parsed,
832 or the first tag is found to send any data to the client.
833 [Paul J. Reder <rederpj@raleigh.ibm.com>]
835 *) Fix mod_info, so that <Directory> and <Location> directives are
836 not displayed twice when displaying the current configuration.
837 [Ryan Morgan <rmorgan@covalent.net>]
839 *) Add config directives to override DEFAULT_ERROR_MSG and
840 DEFAULT_TIME_FORMAT. This was sent in as PR 6193.
841 [Dan Rench <drench@xnet.com>]
843 *) Get mod_info building and loading on Win32. [William Rowe]
845 *) Begin to move protocol independant functions out of mod_http. The goal
846 is to have only functions that are HTTP specific in the http directory.
849 Changes with Apache 2.0.13
851 *) Don't assume that there will always be multiple calls to the byterange
852 filter. It is possible that we will need to do byteranges with only
853 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
855 *) Move the error_bucket definition from the http module to the
856 core server. Every protocol will need this ability, not just
859 Changes with Apache 2.0.12
861 *) Modify mod_file_cache to save pre-formatted strings for
862 content-length and last-modified headers for performance.
863 [Mike Abbot <mja@trudge.engr.sgi.com>]
865 *) Namespace protect IOBUFSIZ since it is exposed in the API.
866 [Jon Travis <jtravis@covalent.net>]
868 *) Use "Basic" authentication instead of "basic" in ab, as the spec
869 says we should. [Andre Breiler <andre.breiler@rd.bbc.co.uk>]
871 *) Fix a seg fault in mod_userdir.c. We used to use the pw structure
872 without ever filling it out. This fixes PR 7271.
873 [Taketo Kabe <kabe@sra-tohoku.co.jp> and
874 Cliff Woolley <cliffwoolley@yahoo.com>]
876 *) Add a couple of GCC attribute tags to printf style functions.
877 [Jon Travis <jtravis@covalent.net>]
879 *) Add the correct language tag for interoperation with the Taiwanese
880 versions of MSIE and Netscape. [Clive Lin <clive@CirX.ORG>] PR#7142
882 *) Migrate the perchild MPM to use the new apr signal child, and
883 APR thread functions. [Ryan Bloom]
885 *) Close one copy of the CGI's stdout before creating the new process.
886 The CGI will still have stdout, because we have already dup'ed it.
887 This keeps Apache from waiting forever to send the results of a CGI
888 process that has forked a long-lived child process.
889 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
891 *) Remove the rest of the pthreads functions from the threaded MPM.
892 This requires the APR support for a signal thread that was just
895 *) Make mod_dir use a fixup for sending a redirect to the browser.
896 Before this, we were using a handler, which doesn't make much
897 sense, because the handler wasn't generating any data, it would
898 either return a redirect error code, or DECLINED. This fits the
899 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
901 *) Make the threaded MPM use APR threads instead of pthreads.
904 *) Get mod_tls to the point where it actually appears to work in all cases.
907 *) implement --enable-modules and --enable-mods-shared for "all" and
910 *) Move the threaded MPM to use APR locks instead of pthread locks.
913 *) Rename mpmt_pthread to threaded. This is more in line with the
914 fact that mpmt_pthread shouldn't be using pthreads directly, and
915 it is a smaller name that doesn't tie into anything.
918 *) Rename the module structures so that the exported symbol matches
919 the file name, and it is easier to automate the installation
920 process (generating LoadModule directives from the module filenames).
923 *) Remove the coalesce filter. With the ap_f* functions, this filter
924 is no longer needed. [Ryan Bloom]
926 Changes with Apache 2.0.11
928 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
929 added feature of allowing a uid/gid per child process. If no
930 uid/gid is specified, then Perchild behaves exactly like dexter.
933 *) Get perchild building again. [Ryan Bloom]
935 *) Don't disable threads just because we are using the prefork MPM.
936 If somebody wants to compile without threads, they must now add
937 --disable-threads to the configure command line. [Ryan Bloom]
939 *) Begin to move the calls to update_child_status into common code, so
940 that each individual MPM does not need to update the scoreboard itself.
943 *) Allow mod_tls to compile under Unix boxes where openssl has been
944 installed to the system include files.
945 [Gomez Henri <new-httpd@slib.fr>]
947 *) Cleanup the mod_tls configure process. This should remove any need
948 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
949 configure doesn't check that yet. [Ryan Bloom]
951 *) Add a very early prototype of SSL support (in mod_tls.c). It is
952 vital that you read modules/tls/README before attempting to build
955 *) Fix a potential seg fault on all platforms. David Reid fixed this
956 on BEOS, but the problem could happen anywhere, so we don't want
957 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
959 *) Add new LogFormat directive, %D, to log time it takes to serve a
960 request in microseconds. [Bill Stoddard]
962 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
963 SetOutputFilter. This corresponds nicely with the other Set
964 directives, which operate on containers while the Add* directives
965 tend to work directly on extensions. [Ryan Bloom]
967 *) Cleanup the header handling a bit. This uses the apr_brigade_*
968 functions for the buffering so that we don't need to compute
969 the length of the headers before we actually create the header
972 *) Allow filters to buffer data using the ap_f* functions. These have
973 become macros that resolve directly to apr_brigade_*.
976 *) Get the Unix MPM's to do a graceful restart again. If we are going
977 to register a cleanup with ap_cleanup_scoreboard, then we have to
978 kill the cleanup with the same function, and that function can't be
981 *) Install all required header files. Without these, it was not
982 possible to compile some modules outside of the server.
985 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
986 forward from 1.3 to 2.0, we missed a single line, which broke regex
987 aliases. [Ryan Bloom]
989 *) We have a poor abstraction in the protocol. This is a temporary
990 hack to fix the bug, but it will need to be fixed for real. If
991 we find an error while sending out a custom error response, we back
992 up to the first non-OK request and send the data. Then, when we send
993 the EOS from finalize_request_protocol, we go to the last request,
994 to ensure that we aren't sending an EOS to a request that has already
995 received one. Because the data is sent on a different request than
996 the EOS, the error text never gets sent down the filter stack. This
997 fixes the problem by finding the last request, and sending the data
998 with that request. [Ryan Bloom]
1000 *) Make the server status page show the correct restart time, and
1001 thus the proper uptime. [Ryan Bloom]
1003 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
1004 should reduce the amount of duplicate code that is required to
1005 create CGI processes.
1006 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1008 *) ap_new_connection() closes the socket and returns NULL if a socket
1009 call fails. Usually this is due to a connection which has been
1010 reset. [Jeff Trawick]
1012 *) Move the Apache version information out of httpd.h and into release.h.
1013 This is in preparation for the first tag with the new tag and release
1014 system. [Ryan Bloom]
1016 *) Begin restructuring scoreboard code to enable adding back in
1017 the ability to use IPC other than shared memory.
1018 Get mod_status working on Windows again. [Bill Stoddard]
1020 *) Make mod_status work with 2.0. This will work for prefork,
1021 mpmt_pthread, and dexter. [Ryan Bloom]
1023 *) Correct a typo in httpd.conf.
1024 [Kunihiro Tanaka <tanaka@apache.or.jp>] PR#7154
1026 *) Really fix mod_rewrite map lookups this time. [Tony Finch]
1028 *) Get the correct IP address if ServerName isn't set and we can't
1029 find a fully-qualified domain name at startup.
1030 PR#7170 [Danek Duvall <dduvall@eng.sun.com>]
1032 *) Make mod_cgid work with SuExec. [Ryan Bloom]
1034 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
1035 'extra' stat's for user/group since they should never occur, and now
1036 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
1037 volumes. [William Rowe]
1039 *) Adopt apr features to simplify mod_includes. This changes the
1040 behavior of the USER_NAME variable, unknown uid's are now reported
1041 as USER_NAME="<unknown>" rather than the old user#000 result.
1042 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
1044 *) Adopt apr features for simplifing mod_userdir, and accept the new
1045 Win32/OS2 exceptions without hiccuping. [William Rowe]
1047 *) Replace configure --with-optim option by using and saving the
1048 environment variable OPTIM instead. This is needed because configure
1049 options do not support multiple flags separated by spaces.
1052 *) Fix some byterange handling. If we get a byte range that looks like
1053 "-999999" where that is past the end of the file, we should return
1054 a PARTIAL CONTENT status code, and return the whole file as one big
1055 byterange. This matches the 1.3 handling now. [Ryan Bloom]
1057 *) Make the error bucket a real meta-data bucket. This means that the
1058 bucket length is 0, and a read returns NULL data. If one of these
1059 buckets is passed down after the headers are sent, this data will
1060 just be ignored. [Greg Stein]
1062 *) The prefork MPM wasn't killing child processes correctly if a restart
1063 signal was received while the process was serving a request. The child
1064 process would become the equivalent of a second parent process. If
1065 we break out of the accept loop, then we need to do die after cleaning
1066 up after ourselves. [Ryan Bloom]
1068 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
1069 restarts. [Ryan Bloom]
1071 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
1072 the most optimal APR_FINFO_wanted bits. This spares Win32 from
1073 performing very expensive owner, group and permission lookups
1074 and allows the server to function until these apr_finfo_t fields
1075 are implemented under Win32. [William Rowe]
1077 *) Support for typedsafe optional functions - that is functions exported by
1078 optional modules, which, therefore, may or may not be present, depending
1079 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
1080 for sample code. [Ben Laurie]
1082 *) filters can now report an HTTP error to the server. This is done
1083 by sending a brigade where the first bucket is an error_bucket.
1084 This bucket is a simple bucket that stores an HTTP error and
1085 a string. Currently the string is not used, but it may be needed
1086 to output an error log. The http_header_filter will find this
1087 bucket, and output the error text, and then return
1088 AP_FILTER_ERROR, which informs the server that the error web page
1089 has already been sent. [Ryan Bloom]
1091 *) If we get an error, then we should remove all filters except for
1092 those critical to serving a web page. This fixes a bug, where
1093 error pages were going through the byterange filter, even though
1094 that made no sense. [Ryan Bloom]
1096 *) Relax the syntax checking of Host: headers in order to support
1097 iDNS. PR#6635 [Tony Finch]
1099 *) Cleanup the byterange filter to use the apr_brigade_partition
1100 and apr_bucket_copy functions. This removes a lot of very messy
1101 code, and hopefully makes this filter more stable.
1104 *) Remove AddModule and ClearModuleList directives. Both of these
1105 directives were used to ensure that modules could be enabled
1106 in the correct order. That requirement is now gone, because
1107 we use hooks to ensure that modules are in the correct order.
1110 *) When SuExec is specified, we need to add it to the list of
1111 targets to be built. If we don't, then any changes to the
1112 configuration won't affect SuExec, unless 'make suexec' is
1113 specifically run. [Ryan Bloom]
1115 *) Cleaned out open_file from mod_file_cache, as apr now accepts
1116 the APR_XTHREAD argument to open a file for consumption by
1117 parallel threads on win32. [William Rowe]
1119 *) Correct a bug in determining when we follow symlinks. The code
1120 expected a stat -1 result, not an apr_status_t positive error.
1121 Also check if the APR_FINFO_USER fields are valid before we
1122 follow the link. [William Rowe]
1124 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
1125 mpm_common.c. These functions are only valid on some platforms,
1126 so they should not be in the main-line code. [Ryan Bloom]
1128 *) Remove ap_chdir_file(). This function is not thread-safe,
1129 and nobody is currently using it. [Ryan Bloom]
1131 *) Do not try to run make depend if there are no .c files in the
1132 current directory, doing so makes `make depend` fail.
1135 *) Update highperformance.conf to work with either prefork or
1136 pthreads mpms. [Greg Ames]
1138 *) Stop checking to see if this is a pipelined request if we know
1139 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
1140 This keeps us from making an extra read call when serving a 1.0
1141 request. [Ryan Bloom and Greg Stein]
1143 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
1144 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
1145 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]
1147 *) Fix the RFC number mentioned when complaining about a missing
1148 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]
1150 *) Fix an endless loop in ab which occurred when ab was posting
1151 and the server dropped the connection unexpectedly.
1154 *) Fix a segfault while handling request bodies in ap_http_filter().
1155 This problem has been seen with mod_dav usage as well as with
1156 requests where the body was just being discarded. [Jeff Trawick]
1158 *) Some adjustment on the handling and automatic setting (via
1159 hints.m4) of various compilation flags (eg: CFLAGS). Also,
1160 add the capability to specify flags (NOTEST_CFLAGS and
1161 NOTEST_LDFLAGS) which are used to compile Apache, but
1162 not used during the configuration process. Useful for
1163 flags like "-Werror". [Jim Jagielski]
1165 *) Stop using environment variables to force debug mode or
1166 no detach. We now use the -D command line argument to
1167 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
1168 [Greg Stein, Ryan Bloom]
1170 *) Change handlers to use hooks. [Ben Laurie]
1172 *) Stop returning copies of filenames from both apr_file_t and
1173 apr_dir_t. We pstrdup the filenames that we store in the
1174 actual structures, so we don't need to pstrdup the strings again.
1177 *) mod_cgi: Fix some problems where the wrong error value was being
1178 traced. [Jeff Trawick]
1180 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
1183 *) Add generic hooks. [Ben Laurie]
1185 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
1187 *) Fix a segfault caused by mod_ext_filter when the external filter
1188 program does not exist. [Jeff Trawick]
1190 *) Fix an output truncation error when on an HTTP >= 1.0 request an
1191 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
1192 was served through mod_charset_lite (or anything else that would
1193 create a transient bucket in this size range). ap_bucket_make_heap()
1194 silently failed (fixed), transient_setaside() discovered it, but
1195 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
1197 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
1198 is that some browsers send extra lines at the end of POST requests, and
1199 we don't want to delay sending data back to the user just because the
1200 browser isn't well behaved. [Ryan Bloom]
1202 *) Get SuEXEC working again. We can't send absolute paths to suExec
1203 because it refuses to execute those programs. SuEXEC also wasn't
1204 always recognizing configuration changes made using the autoconf
1207 *) Allow the buildconf process to find the config.m4 files in the correct
1208 order. Basically, we can now name config.m4 files as config\d\d.m4,
1209 and we will sort them correctly when inserting them into the build
1210 process. [Ryan Bloom]
1212 *) Get mod_cgid to use apr calls for creating the actual CGI process.
1213 This also allows mod_cgid to use ap_os_create_priviledged_process,
1214 thus allowing for SuExec execution from mod_cgid. Currently, we do
1215 not support everything that standard SuExec supports, but at least
1216 it works minimally now. [Ryan Bloom]
1218 *) Allow SuExec to be configured from the ./configure command line.
1221 *) Update some of the docs in README and INSTALL to reflect some of
1222 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1224 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1225 need to call sendfile again. This gets us serving large files
1226 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1228 *) Get the support programs building cleanly again.
1229 [Cliff Woolley <cliffwoolley@yahoo.com>]
1231 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1232 current directory logic now backs up over bin/ to determine the
1233 server root from the Apache.exe path.
1235 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1236 loadable modules, dynamic libs are all named libfoo.dll, and the
1237 makefile.win populates the include, lib and libexec directories.
1239 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1240 Apache gets IPv6 listening sockets by default. Additionally, the
1241 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1242 numeric address strings (e.g., "Listen [fe80::1]:8080").
1245 *) Modify the install directory layout. Modules are now installed in
1246 modules/. Shared libraries should be installed in libraries/, but
1247 we don't have any of those on Unix yet. All install directories
1248 are modifyable at configure time. [Ryan Bloom]
1250 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1252 *) Get the functions in server/linked into the server, regardless of
1253 which modules linked into the server. This uses the same hack
1254 for Apache that we use for APR and apr-util to ensure all of the
1255 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1256 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1257 the scripts a bit easier.
1260 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1261 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1263 *) Get all of the auth modules to the point that they will install and
1264 be loadable into the server. Our new build/install mechanism expects
1265 that all modules will have a common name format. The auth modules
1266 didn't use that format, so we didn't install them properly.
1269 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1270 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1272 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1274 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1275 after the end of the response. [Ryan Bloom]
1277 *) Get byterange requests working with responses that do not have a
1278 content-length. Because of the way byterange requests work, we have to
1279 have all of the data before we can actually do the byterange, so we
1280 can compute the content-length in the byterange filter.
1283 *) Get exe CGI's working again on Windows.
1286 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1287 they keep track of whether or not their post config hook has been
1288 called before. Instead of a static variable (which is replaced when
1289 the DSO is loaded a second time), use userdata in the process pool.
1292 Changes with Apache 2.0a9
1294 *) Win32 now requires perl to complete the final install step for users
1295 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1296 and installs the conf, htdocs and htdocs/manual directories.
1299 *) Make mod_include use a hash table to associate directive tags with
1300 functions. This allows modules to implement their own SSI tags easily.
1301 The idea is simple enough, a module can insert it's own tag and function
1302 combination into a hash table provided by mod_include. While mod_include
1303 parses an SSI file, when it encounters a tag in the file, it does a
1304 hash lookup to find the function that implements that tag, and passes
1305 all of the relevant data to the function. That function is then
1306 responsible for processing the tag and handing the remaining data back
1307 to mod_include for further processing.
1308 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1310 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1311 fewer parameters: the local and remote socket addresses were removed
1312 from the parameter list because all required information is available
1313 via the APR socket. [Jeff Trawick]
1315 *) Distribution directory structure reorganized to reflect a
1316 normal source distribution with external install targets.
1319 *) The MPMs that need multiple segments of shared memory now create
1320 two apr_shmem_t variables, one for each shared memory allocation.
1321 the problem is that we can't determine how much memory will be required
1322 for shared memory allocations once we try to allocate more than one
1323 variable. The MM code automatically aligns the shared memory allocations,
1324 so we end up needing to pad the amount of shared memory we want based
1325 on how many variables will be allocated out of the shared memory segment.
1326 It is just easier to create a second apr_shmem_t variable, and two
1327 shmem memory blocks.
1330 *) Cleanup the export list a bit. This creates a single unified list of
1331 functions exported by APR. The export list is generated at configure
1332 time, and that list is then used to generate the exports.c file.
1333 Because of the way the export list is generated, we only export those
1334 functions that are valid on the platform we are building on.
1337 *) Enable logging the cookie with mod_log_config
1338 [Sander van Zoest <sander@covalent.net>]
1340 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1343 *) Added lib/aputil/ as a placeholder for utility functions which are not
1344 specific to the Apache HTTP Server (but do not make sense with APR).
1345 The first utility is "apu_dbm": a set of functions to work with DBM
1346 files. This first version can be compiled for SDBM or GDBM databases.
1349 *) Complete re-write of mod_include. This makes mod_include a filter that
1350 uses buckets directly. This has now served the FAQ correctly.
1351 [Paul Reder <rederpj@raleigh.ibm.com>]
1353 *) Allow modules to specify the first filter in a sub_request when
1354 making the sub_request. This keeps modules from having to change the
1355 output_filter immediately after creating the sub-request, and therefore
1356 skip the sub_req_output_filter. [Ryan Bloom]
1358 *) Update ab to accept URLs with IPv6 literal address strings (in the
1359 format described in RFC 2732), and to build Host header fields in
1360 the same format. This allows IPv6 literal address strings to be
1361 used with ab. This support has been tested against Apache 1.3 with
1362 the KAME patch, but Apache 2.0 does not yet work with this format
1363 of the Host header field. [Jeff Trawick]
1365 *) Accomodate an out-of-space condition in the piped logs and the
1366 rotatelogs.c code, and no longer churn log processes for this
1367 condition. [Victor J. Orlikowski]
1369 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1372 Changes with Apache 2.0a8
1374 *) Add a directive to mod_mime so that filters can be associated with
1378 *) Get multi-views working again. We were setting the path_info
1379 field incorrectly if we couldn't find the specified file.
1382 *) Fix 304 processing. The core should never try to send the headers
1383 down the filter stack. Always, just setup the table in the request
1384 record, and let the header filter convert it to data that is ready
1388 *) More fixes for the proxy. There are still bugs in the proxy code,
1389 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1393 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1396 *) APR: Add new apr_getopt_long function to handle long options.
1397 [B. W. Fitzpatrick <fitz@red-bean.com>]
1399 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1400 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1401 hostname resolution/address string parsing and building
1402 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1403 of one of the apr_sockaddr_t structures for a socket. Change
1404 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1406 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1407 I have proxied pages with it, cleanup will commence soon.
1410 *) Make the proxy work with filters. This isn't perfect, because we
1411 aren't dealing with the headers properly. [Ryan Bloom]
1413 *) Do not send a content-length iff the C-L is 0 and this is a head
1414 request. [Ryan Bloom]
1416 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1417 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1419 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1421 *) Get the default_handler to stop trying to deal with HEAD requests.
1422 The idea is to let the content-length filter compute the C-L before
1423 we try to send the data. If we can get the C-L correctly, then we
1424 should send it in the HEAD response.
1427 *) The Header filter can now determine if a body should be sent based
1428 on r->header_only. The general idea of this is that if we delay
1429 deciding to send the body, then we might be able to compute the
1430 content-length correctly, which will help caching proxies to cache
1431 our data better. Any handler that doesn't want to try to compute
1432 the content-length can just send an EOS bucket without data and
1433 everything will just work.
1436 *) Add the referer to the error log if one is available.
1437 [Markus Gyger <mgyger@itr.ch>]
1439 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1440 change, the root of the configuration tree has been exposed to modules
1442 [Ryan Morgan <rmorgan@covalent.net>]
1444 *) Get the core_output_filter to use the bucket interface directly.
1445 This keeps us from calling the content-length filter multiple times
1446 for a simple static request.
1449 *) We are sending the content-type correctly now.
1450 [Ryan Bloom and Will Rowe]
1452 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1453 a bogus bytes-sent value when the only thing being sent was trailers
1454 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1456 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1457 hints file to determine which platforms define
1458 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1461 *) APR: add apr_get_home_directory() [Jeff Trawick]
1463 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1465 *) Not all platforms have INADDR_NONE defined by default. Apache
1466 used to make this check and define INADDR_NONE if appropriate,
1467 but APR needs the check too, and I suspect other applications will
1468 as well. APR now defines APR_INADDR_NONE, which is always a valid
1469 value on all platforms.
1470 [Branko Èibej <brane@xbc.nu>]
1472 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1473 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1475 *) Relax the syntax checking of Host: headers in order to support
1476 iDNS. PR#6635 [Tony Finch]
1478 *) When reading from file buckets we convert to an MMAP if it makes
1479 sense. This also simplifies the default handler because the
1480 default handler no longer needs to try to create MMAPs.
1483 *) BUFF has been removed from the main server. The BUFF code will remain
1484 in the code until it has been purged from the proxy module as well.
1487 *) Byteranges have been completely re-written to be a filter. This
1488 has been tested, and I believe it is working correctly, but it could
1489 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1490 the output from 1.3, the only difference being that 1.3 includes
1491 a content-length in the response, and this does not.
1494 *) APR read/write functions and bucket read functions now operate
1495 on unsigned integers, instead of signed ones. It doesn't make
1496 any sense to use signed ints, because we return the error codes,
1497 so if we have an error we should report 0 bytes read or written.
1500 *) Always compute the content length, whether it is sent or not.
1501 The reason for this, is that it allows us to correctly report
1502 the bytes_sent when logging the request. This also simplifies
1503 content-length filter a bit, and fixes the actual byte-reporing
1504 code in mod_log_config.c
1507 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1508 it says, because it was only used by EOS and FLUSH buckets. Since
1509 neither of those are required at the end of a brigade, this was
1510 really signifying FLUSH_THE_DATA, but that can be determined better
1511 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1512 buckets now return a length of 0, which is actually the amount of data
1513 read, so they make more sense.
1516 *) Allow the core_output_filter to save some data past the end of a
1517 request. If we get an EOS bucket, we only send the data if it
1518 makes sense to send it. This allows us to pipeline request
1519 responses. As a part of this, we also need to allocate mmap
1520 buckets out of the connection pool, not the request pool. This
1521 allows the mmap to outlive the request.
1524 *) Make blocking and non-blocking bucket reads work correctly for
1525 sockets and pipes. These are the only bucket types that should
1526 have non-blocking reads, because the other bucket types should
1527 ALWAYS be able to return something immediately.
1530 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1531 server, but use Ctrl+Break to initiate a graceful restart
1532 instead of duplicating behavior. [John Sterling]
1534 *) Patch mod_autoindex to set the Last-Modified header based on
1535 the directory's mtime, and add the ETag header. [William Rowe]
1537 *) Merge the 1.3 patch to add support for logging query string in
1538 such a way that "%m %U%q %H" is the same as "%r".
1541 *) Port three log methods from mod_log_config 1.3 to 2.0:
1542 CLF compliant '-' byte count, method and protocol.
1545 *) Add a new LogFormat directive, %c, that will log connection
1546 status at the end of the response as follows:
1547 'X' - connection aborted before the response completed.
1548 '+' - connection may be kept-alive by the server.
1549 '-' - connection will be closed by the server.
1552 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1553 Unicode file names and paths for Win32, and tag the Content-Type
1554 from mod_autoindex to reflect that charset if the the feature
1555 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1557 *) Compute the content length (and add appropriate header field) for
1558 the response when no content length is available and we can't use
1559 chunked encoding. [Jeff Trawick]
1561 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1562 so that content input filters get dechunked data when using
1563 the default handler. Also removed REQUEST_CHUNKED_PASS.
1566 *) Add mod_ext_filter as an experimental module. This module allows
1567 the administrator to use external programs as filters. Currently,
1568 only filtering of output is supported. [Jeff Trawick]
1570 *) Most Apache functions work on EBCDIC machines again, as protocol
1571 data is now translated (again). [Jeff Trawick]
1573 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1574 the EBCDIC support. They are noops on ASCII machines, so this
1575 type of translation doesn't have to be surrounded by #ifdef
1576 CHARSET_EBCDIC. [Jeff Trawick]
1578 *) Fix mod_include. tag commands work again, and the server will
1579 send the FAQ again. This also allows mod_include to set aside
1580 buckets that include partial buckets.
1581 [Ryan Bloom and David Reid]
1583 *) Add suexec support back. [Manoj Kasichainula]
1585 *) Lingering close now uses the socket directly instead of using
1586 BUFF. This has been tested, but since all we can tell is that it
1587 doesn't fail, this needs to be really hacked on.
1590 *) Allow filters to modify headers and have those headers be sent to
1591 the client. The idea is that we have an http_header filter that
1592 actually sends the headers to the network. This removes the need
1593 for the BUFF to send headers.
1596 *) Charset translation: mod_charset_lite handles translation of
1597 request bodies. Get rid of the xlate version of ap_md5_digest()
1598 since we don't compute digests of filtered (e.g., translated)
1599 response bodies this way anymore. (Note that we don't do it at
1600 all at the present; somebody needs to write a filter to do so.)
1603 *) Input filters and ap_get_brigade() now have a input mode parameter
1604 (blocking, non-blocking, peek) instead of a length parameter.
1607 *) Update the mime.types file to the registered media types as
1608 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1611 *) Namespace protect some macros declared in ap_config.h
1614 *) Support HTTP header line folding with input filtering.
1617 *) Mod_include works again. This should still be re-written, but at
1618 least now we can serve an SHTML page again.
1621 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1622 to both the BUFF and the socket in the conn_rec. Functions that
1623 want to use the BUFF can, functions that want to use the socket,
1624 can. They point to the same place.
1627 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1628 [Tomas "Ögren" <stric@ing.umu.se>]
1630 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1631 associated pool goes away. (APR pipes on OS/2 were already had this
1632 logic.) This resolvs a fatal file descriptor leak with CGIs.
1635 *) The final line of the config file was not being read if there was
1636 no \n at the end of it. This was caused by apr_fgets returning
1637 APR_EOF even though we had read valid data. This is solved by
1638 making cfg_getline check the buff that was returned from apr_fgets.
1639 If apr_fgets return APR_EOF, but there was data in the buf, then we
1640 return the buf, otherwise we return NULL.
1643 *) Piped logs work again in the 2.0 series.
1646 *) Restore functionality broken by the mod_rewrite security fix:
1647 rewrite map lookup keys and default values are now expanded
1648 so that the lookup can depend on the requested URI etc.
1649 PR #6671 [Tony Finch]
1651 *) Tighten up the syntax checking of Host: headers to fix a
1652 security bug in some mass virtual hosting configurations
1653 that can allow a remote attacker to retrieve some files
1654 on the system that should be inaccessible. [Tony Finch]
1656 *) Add a pool bucket type. This bucket is used for data allocated out
1657 of a pool. If the pool is cleaned before the bucket is destroyed, then
1658 the data is converted to a heap bucket, allowing it to survive the
1662 *) Add a flush bucket. This allows modules to signal that the filters
1663 should all flush whatever data they currently have. There is no way
1664 to actually force them to do this, so if a filter ignores this bucket,
1665 that's life, but at least we can try with this.
1668 *) Add an output filter for sub-requests. This filter just strips the
1669 EOS bucket so that we don't confuse the main request's core output
1670 filter by sending multiple EOS buckets. This change also makes sub
1671 requests start to send EOS buckets when they are finished.
1674 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1675 makes ap_bucket_destroy a return void, which is okay because it
1676 used to always return APR_SUCCESS, and nobody ever checked its
1677 return value anyway.
1678 [Cliff Woolley <cliffwoolley@yahoo.com>]
1680 *) Remove the index into the bucket-type table from the buckets
1681 structure. This has now been replaced with a pointer to the
1682 bucket_type. Also add some macros to test the bucket-type.
1685 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1686 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1687 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1688 All _VAR_ flavors changes to _DATA to be absolutely clear.
1691 *) Add support for /, //, //servername and //server/sharename
1692 parsing of <Directory> blocks under Win32 and OS2.
1693 [Tim Costello, William Rowe, Brian Harvard]
1695 *) Remove the function pointers from the ap_bucket type. They have been
1696 replaced with a global table. Modules are allowed to register bucket
1697 types and use then use those buckets.
1700 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1701 once we finish writing the request body to the cgi child process;
1702 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1703 worked without this change (for reasons I don't understand), but large
1704 ones didn't. [Jeff Trawick]
1706 *) Remove file bucket specific information from the ap_bucket type.
1707 This has been moved to a file_bucket specific type that hangs off
1708 the data pointer in the ap_bucket type.
1711 *) Input filtering now has a third argument. This is the amount of data
1712 to read from lower filters. This argument can be -1, 0, or a positive
1713 number. -1 means give me all the data you have, I'll deal with it and
1714 let you know if I need more. 0 means give me one line and one line
1715 only. A positive number means I want no more than this much data.
1717 Currently, only 0 and a positive number are implemented. This allows
1718 us to remove the remaining field from the conn_rec structure, which
1722 *) Big cleanup of the input filtering. The goal is that http_filter
1723 understands two conditions, headers and body. It knows where it is
1724 based on c->remaining. If c->remaining is 0, then we are in headers,
1725 and http_filter returns a line at a time. If it is not 0, then we are
1726 in body, and http_filter returns raw data, but only up to c->remaining
1727 bytes. It can return less, but never more.
1728 [Greg Ames, Ryan Bloom, Jeff Trawick]
1730 *) mod_cgi: Write all of the request body to the child, not just what
1731 the kernel would accept on the first write. [Jeff Trawick]
1733 *) Back out the change that moved the brigade from the core_output_filters
1734 ctx to the conn_rec. Since all requests over a given connection
1735 go through the same core_output_filter, the ctx pointer has the
1739 *) Fix another bug in the send_the_file() read/write loop. A partial
1740 send by apr_send would cause unsent data in the read buffer to
1741 get clobbered. Complete making send_the_file handle partial
1742 writes to the network.
1745 *) Fix a couple of type fixes to allow compilation on AIX again
1746 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1748 *) Fix bug in send_the_file() which causes offset to be ignored
1749 if there are no headers to send.
1752 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1753 filter. Useful for supporting Windows 9* with a binary
1754 compiled on Windows NT.
1757 Changes with Apache 2.0a7
1759 *) Reimplement core_output_filter to buffer/save bucket brigades
1760 across multiple calls to the core_filter. The brigade will be
1761 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1762 thresholds are hit or the EOS bucket is received.
1765 *) Create experimental filter (buffer_filter) that coalesces bytes
1766 into one large buffer before invoking the next filter in the
1767 chain. This filter is particularly useful with the current
1768 implementation of mod_autoindex when it inserted above the
1769 chunk_filter. mod_autoindex generates a lot of brigades that
1770 containing buckets holding just a few bytes each. The
1771 buffer_filter coalesces these buckets into a single large bucket.
1774 *) Add apr_sendfile() support into the core_output_filter.
1777 *) Add apr_sendv() support into the core_output_filter.
1780 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1781 [Mike Abbott <mja@sgi.com>]
1783 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1784 make much sense, because Apache uses buckets instead of BUFFs now.
1787 *) send_the_file now falls back to a read/write loop on platforms that
1788 do not have sendfile.
1789 [Ryan Bloom and Brian Havard]
1791 *) Install apachectl correctly, and substitute the proper values so
1792 that it works again. [Ryan Bloom]
1794 *) Better(??) handle platforms that lack sendfile().
1797 *) APR now has UUID generation/formatting/parsing support.
1800 *) Begin the http_filter. This is an input filter that understands
1801 the absolute basic amount required to parse an HTTP Request. The
1802 goal is to be able to split headers from request body before passing
1803 the data back to the other filters.
1806 *) Bring forward from 1.3.13 the config directory implementation
1809 *) install apxs if it is created
1812 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1813 conversions. [William Rowe]
1815 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1816 ap_add_output_filter(). [Jeff Trawick]
1818 *) Multiple build and configuration fixes
1821 -add datadir and localstatedir substitutions
1823 -fix logfilename misspelling
1824 -fix evaluation of installation dir variables and
1825 -replace $foobar by $(foobar) to be usefull in the makefile
1829 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1830 $CC_FOR_BUILD is still missing
1831 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1832 -add missing "AR=@AR@" to severaly Makefile.in's
1833 -cache result for "struct rlimit"
1834 -compile all helper programs with native and cross compiler
1835 and use the native version to generate header file
1836 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1838 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1840 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1842 *) Fix a bug where a client which only sends \n to delimit header
1843 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1844 message. Start working on ebcdic co-existance with input
1846 [William Rowe, Greg Ames]
1848 *) If mod_so is enabled in the server always create libexec, even
1849 if there are no modules installed in this directory. This is a
1850 requirement for APXS to work correctly.
1853 *) Connection oriented output filters are now stored in the
1854 conn_rec instead of the request_rec. This allows us to add the
1855 output filter in the pre-connection phase instead of the
1856 post_read_request phase, which keeps us from trying to write an
1857 error page before we have a filter to write to the network.
1858 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1860 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1861 mmap can be used across multiple buckets (default_handler with
1862 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1863 the mmap itself can't be associated with the bucket.
1866 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1869 *) Radical surgery to improve mod_isapi support under Win32.
1870 Includes a number of newer ServerSupportFunction calls, support
1871 for ReadClient (in order to retrieve POSTs greater than 48KB),
1872 and general bug fixes to more reliably load ISAPI .dll's and
1873 prevent leaking handle resources. Note: There are still
1874 discrepancies between IIS's and Apache's ServerVariables, and
1875 async calls are still not supported. Additional warnings are
1876 logged to facilitate debugging of unsupported ISAPI calls.
1879 *) Add input filtering to Apache. The basic idea for the input
1880 filters is the same as the ideas for output filters. The biggest
1881 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1882 should be called, and the order of execution for the filter itself is
1883 different. When writing an output filter, a brigade is passed in,
1884 and filters operate directly on that brigade, when done, they call
1885 ap_pass_brigade. Input filters are the exact opposite. Because input
1886 is not a push operation, filters first call ap_get_brigade. When this
1887 function returns, the input filter will be left with a valid brigade.
1888 The input filter should then operate on the brigade, and return.
1891 *) Fix building on BSD/OS using its native make. The build system
1892 falls back to the BSD .include directive on that host platform.
1895 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1896 SHA1 and plaintext password encodings. Make feature tests a
1897 bit more flexible. [William Rowe]
1899 *) Charset translation: mod_charset_lite handles output content
1900 translation in a filter. mod_charset_lite no longer ignores
1901 subrequests. A bunch of cruft related to BUFF's support for
1902 translating request and response bodies was removed.
1905 *) Move the addition of the CORE filter to the post_read_request
1906 hook in http_core.c. This removes the need to add the filter in
1907 multiple places and allows for an SSL module to be added much
1908 simpler. [Ryan Bloom]
1910 *) Fix a security problem that affects certain configurations of
1911 mod_rewrite. If the result of a RewriteRule is a filename that
1912 contains expansion specifiers, especially regexp backreferences
1913 $0..$9 and %0..%9, then it may be possible for an attacker to
1914 access any file on the web server. [Tony Finch]
1916 *) Fix a bug where errors that are detected during early request parsing
1917 don't produce visible HTTP error messages at the browser, because
1918 the core_filter wasn't present. [Greg Ames]
1920 *) Provide apr_socklen_t as a portability aid.
1921 [Victor J. Orlikowski]
1923 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1924 as well as a comment arg to the add, adduser and update cmds.
1925 update allows the user to clear or preserve pw/groups/comment.
1926 Fixed a bug in dbmmanage that prevented the check option from
1927 parsing a password followed by :group... text. Corrected the
1928 seed calcualation for Win32 systems, and added -lsdbm support.
1931 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1934 *) Avoid a segfault when parsing .htaccess files. An
1935 uninitialized tree pointer was passed to ap_build_config().
1938 *) Change the way that inet_addr & inet_network are checked for
1939 in APR's configure process to allow BeOS BONE to correctly
1940 find them. With this change BeOS BONE now builds from source
1941 with no problems. [David Reid]
1943 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1944 the end of the parameters to execve() was stored in the wrong
1945 location, overlaying the storage beyond the newargs[] array and
1946 also passing uninitialized storage to execve(), which would
1947 sometimes fail with EFAULT. [Jeff Trawick]
1949 *) Fix a bug parsing configuration file containers. With a sequence
1950 like this in the config file
1952 <IfModule mod_kilroy.c>
1955 <IfModule mod_lovejoy.c>
1960 the second container would be terminated at the blank line due to
1961 sediment in the buffer from reading the prior </IfModule> and an
1962 error message would be generated for the real </IfModule> for the
1963 second container. Also due to this problem, any two characters
1964 could be used for "</" in the close of a container.
1967 *) ap_add_filter prototype changed to remove the ctx pointer. The
1968 pointer still remains in the filter structure, but it can not be
1969 a part of the ap_add_filter prototype. The reason is that when
1970 the core uses AddFilter to add a filter to the stack it doesn't
1971 know how to allocate the ctx pointer, or even how much memory should
1972 be allocated. The filters will have to be responsible for allocating
1973 the ctx memory when they need it.
1976 *) Add an AddFilter directive. This directive takes a list of filters
1977 that should be activated for the requested resource.
1980 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1981 some other platforms). [Jeff Trawick]
1983 *) Modify mod_include to be a filter. Currently, it has only been tested
1984 on actual files, but it should work for CGI scripts too.
1987 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1988 writes. apr_flush() for Unix: handle interrupted writes.
1991 *) NameVirtualHost can now take "*" as an argument instead of
1992 an IP address. This allows you to create a purely name-based
1993 virtual hosting server that does not have any IP addresses in
1994 the configuration file and which ignores the local address
1995 of any connections. PR #5595, PR #4455 [Tony Finch]
1997 *) Fix some compile warnings in mod_mmap_static.c
1998 [Mike Abbott <mja@sgi.com>]
2000 *) Fix chunking problem with CGI scripts. The general problem was that
2001 the CGI modules were adding an EOS bucket and then the core added an
2002 EOS bucket. The chunking filter finalizes the chunked response when it
2003 encounters an EOS bucket. Because two EOS buckets were sent, we
2004 finalized the response twice. The fix is to make sure we only send one
2005 EOS, by utilizing a flag in the request_rec.
2008 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
2009 and Win32. Previously, the first read from an apr_file_t set up via
2010 apr_put_os_file() would return a '\0'. [Jeff Trawick]
2012 *) Mod_cgid now creates a single element bucket brigade, with a pipe
2013 bucket, instead of using BUFF's and ap_r*.
2016 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
2017 [Mike Abbott <mja@sgi.com>]
2019 *) Remove ap_bopenf from buff code. This required modifying the file_cache
2020 code to use APR file's directly instead of going through BUFFs.
2023 *) Fix compile break on some platforms for mod_mime_magic.c
2024 [John K. Sterling <sterling@covalent.net>]
2026 *) Fix merging of AddDefaultCharset directive.
2027 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
2029 *) Minor revamp of the rlimit sections of code. We now test
2030 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
2031 is now "available" even if the platform doesn't support
2032 the rlimit family (it's just a noop though). [Jim Jagielski]
2034 *) Migrate the pre-selection of which MPM to use for specific
2035 platforms to hints.m4, which contains (or should contain)
2036 all platform specific "hints". [Jim Jagielski]
2038 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
2041 *) Add tables with non-string/binary values to APR.
2044 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
2047 *) Update PCRE to version 3.2. [Ryan Bloom]
2049 *) Change the way buckets' destroy functions are called so that
2050 they can be more directly used when changing the type of a
2051 bucket in place. [Tony Finch]
2053 *) Add generic support for reference-counting the resources used by
2054 buckets, and alter the HEAP and MMAP buckets to use it. Change
2055 the way buckets are initialised to support changing the type of
2056 buckets in place, and use it when setting aside TRANSIENT buckets.
2057 Change the implementation of TRANSIENT buckets so that it can be
2058 mostly shared with IMMORTAL buckets, which are now implemented.
2061 Changes with Apache 2.0a6
2063 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
2065 *) Add a chunking filter to Apache. This brings us one step closer
2066 to removing BUFF. [Ryan Bloom]
2068 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
2069 added to the stack is the last filter to be called. [Ryan Bloom]
2071 *) Apache 2.0 has been completely documented using Scandoc. The
2072 docs can be generated by running 'make docs'. [Ryan Bloom]
2074 *) Add filtered I/O to Apache. This is based on bucket brigades,
2075 Currently the buckets still use BUFF under the covers, but that
2076 should change quickly. The only currently written filter is the
2077 core filter which just calls ap_bwrite. [The Apache Group]
2079 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
2080 built with thread support. [Jeff Trawick]
2082 *) Abort configuration if --with-layout was specified and there's
2083 no layout definition file. [Ken Coar]
2085 *) Add support for '--with-port=n' option to configure. [Ken Coar]
2087 *) Add support for extension methods for the Allow response header
2088 field, and an API routine for accessing r->allowed and the
2089 list of extension methods in a unified manner. [Ken Coar]
2091 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
2092 [Rob Simonson <simo@us.ibm.com>]
2094 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
2095 APACHE_XLATE builds. [Jeff Trawick]
2097 *) A configuration file parsing problem was fixed. When the
2098 configuration file started with an IfModule/IfDefine container,
2099 only the last statement in the container would be retained.
2102 Changes with Apache 2.0a5
2104 *) Perchild is serving pages after passing them to different child
2105 processes. There are still a lot of bugs, but this does work. I
2106 have made requests against the same installation of Apache, and had
2107 different servers use different user IDs to serve the responses.
2108 This change moves to using socketpair instead of an AF_UNIX socket.
2111 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
2112 It can't seem to pass between child processes yet, but I think we
2113 are closer now than before. This moves us back to using Unix
2114 Domain Sockets. [Ryan Bloom]
2116 *) libapr functions and types renamed with apr_ prefix.
2117 #include "apr_compat.h" for 1.3.x backwards compat
2120 *) Fix problems with APR sockaddr handling on Win32. It didn't always
2121 return the right information on the local socket address.
2122 [Gregory Nicholls <gnicholls@level8.com>]
2124 *) ap_recv() on Win32: Set bytes-read to 0 on error.
2125 [Gregory Nicholls <gnicholls@level8.com>]
2127 *) Add an option to not detach from the controlling terminal without
2128 going into single process mode. This allows for much easier
2129 debugging of the process startup code. [Ryan Bloom]
2131 *) ab: don't use perror() to report the failure of an APR function.
2134 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
2135 scoreboard on graceful restarts.
2138 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
2139 An invalid ap_proc_t was passed to ap_create_process().
2142 *) Allow modules to register filters. Those filters are still
2143 never called, but this is a step in the right direction.
2144 [Ryan Bloom and Greg Stein]
2146 *) Register the mod_cgid daemon process for cleanup so that it is
2147 killed at termination if it does not die when the parent gets
2148 SIGTERM. This change is to fix occasional problems where the
2149 process stays around. Bugs in similar logic in mod_rewrite and
2150 mod_include were also fixed. [Jeff Trawick]
2152 *) Fix a bug in the time handling. Basically, we were imploding a time
2153 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
2154 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
2155 uses those two fields to adjust the time value. Because of the HTTP
2156 spec, both of those values can be zero'ed out safely. This fixes
2157 the bug correctly. [Ryan Bloom]
2159 *) Fix a couple of place in the Windows code where the wrong error
2160 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
2162 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
2164 *) Added the APR_EOL_STR macro for platform dependent differences in
2165 logfiles and other raw text (such as all APR files). Fixes logfiles
2166 not terminated with cr/lf sequences in Win32. [William Rowe]
2168 *) Move all strings functions in APR to src/lib/apr/strings and create
2169 apr_strings.h for the prototypes. [Ryan Bloom]
2171 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
2172 to repeat the syscall until we stop getting EINTR. I noticed a
2173 related problem at termination (SIGTERM) on FreeBSD when using
2174 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
2175 implementation work properly with child init. Previously, ap_lock()
2176 was essentially a no-op because all children were using different
2177 locks and thus nobody ever blocked. [Jeff Trawick]
2179 *) The htdocs/ tree has been moved out of the CVS source tree into
2180 a separate area for easier development. This has NO EFFECT on
2181 end-users or Apache installations. [Ken Coar]
2183 *) Integrate the mod_dav module for WebDAV protocol handling. This
2184 adds the dav and dav_fs modules, the SDBM library, and additional
2185 XML handling utilities. [Greg Stein]
2187 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
2190 *) Update the lib/expat-lite/ library (bring forward changes from
2191 the Apache 1.3 repository). [Greg Stein]
2193 *) If sizeof(long long) == sizeof(long), then prefer long in APR
2194 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
2196 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
2197 machines where sendfile is detected, but nobody has written ap_sendfile.
2198 [Dave Hill <ddhill@zk3.dec.com>]
2200 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
2202 *) ab would start up more connections than needed, then quit when the
2203 desired number were finished. Also fixed a logic error involving
2204 ab keepalives. [Victor J. Orlikowski]
2206 *) WinNT: Implement non-blocking pipes with timeouts to communicate
2207 with CGIs. Apache 2.0a4 had non-blocking pipes but without
2208 timeouts (i.e, if a timeout was specified, the pipe reverted to
2209 a full blocking pipe). Now the behaviour is more in line with
2210 Unix non-blocking pipes.
2213 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
2214 cache open file handles along with accept socket reuse enables
2215 Apache 2.0 to serve non-keepalive requests for static files at
2216 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2217 and Apache 2.0 will serve almost 1200 rps on my system).
2220 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2221 supports two config directives, mmapfile (same behavious as
2222 mod_mmap_static) and cachefile. Use the cachefile directive
2223 to cache open file handles. This directive only works on systems
2224 that have implemented the ap_sendfile API. cachefile works today
2225 on Windows NT, but has not been tested on any flavors of Unix.
2228 *) Cleanup the configuration. With the last few changes the
2229 configuration process automatically:
2230 inherits information about how to build from APR. Allowing
2231 APR to inform Apache that it should or should not use -ldl
2233 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2234 based on the threading model
2236 Apache calls APR's configure process before finishing it's
2237 configuration processing, allowing for more information flow
2242 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2243 with non-zero argument makes the socket non-blocking. BeOS and
2244 OS/2 already worked this way. [Jeff Trawick]
2246 *) ap_close() now calls ap_flush() for buffered files, so write
2247 operations work a whole lot better on buffered files.
2250 *) Fix error messages issued from MPMs which explain where to change
2251 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2254 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2255 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2256 now the way that the blocking state of a pipe is manipulated.
2257 ap_block_pipe() is gone. [Jeff Trawick]
2259 *) Correct the problem where the only local host name that the IP stack
2260 can discover are 'undotted' private names. If no fully qualified
2261 domain name can be identified, the default ServerName will be set to
2262 the machine's IP address string. A warning is always provided if the
2263 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2265 *) Repair problems with config file processing which caused segfault
2266 at init when virtual hosts were defined and which caused ServerName to
2267 be ignored when there was no valid DNS setup. [Jeff Trawick]
2269 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2271 *) Add ap_sendfile implementation for AIX
2272 [Victor J. Orlikowski]
2274 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2275 apr_network_io.h, and apr_thread_proc.h.
2276 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2278 *) Bring the allocation and pool debugging code back into a working
2279 state. This will need to be tested as so far it's only been used on
2282 *) Change configuration command setup to be properly typesafe when in
2283 maintainer mode. Note that this requires a compiler that can initialise
2284 unions. [Ben Laurie]
2286 *) Turn on buffering for config file reads. Part of this was to
2287 repair buffered I/O support in Unix and implement buffered
2288 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2290 *) Win32: Fix problem where UTC offset was not being set correctly
2291 in the access log. Problem reported on news group by Jerry Baker.
2294 *) Fix segfault when reporting this type of syntax error:
2295 "</container> without matching <container> section", where
2296 container is VirtualHost or Directory or whatever.
2299 *) Prevent the source code for CGIs from being revealed when using
2300 mod_vhost_alias and the CGI directory is under the document root
2301 and a user makes a request like http://www.example.com//cgi-bin/cgi
2302 as reported in <news:960999105.344321@ernani.logica.co.uk>
2305 *) Add support for the new Beos NetwOrking Environment (BONE)
2308 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2309 final input char is incomplete; ap_bwrite_xlate() now handles
2310 incomplete final input chars. [Jeff Trawick]
2312 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2313 that a bhalfduplex call occurs before logging or else DNS and
2314 such can delay the last packet of the response. [Dean Gaudet]
2316 *) Some syscall reduction in APR on unix -- don't seek when setting
2317 up an mmap; and don't fcntl() more than once per socket.
2320 *) When mod_cgid is started as root, the cgi daemon now switches
2321 to the configured User/Group (like other httpd processes)
2322 instead of continuing as root. [Jeff Trawick]
2324 *) The prefork MPM now uses an APR lock for the accept() mutex.
2325 It has not been getting a lock at all recently. httpd -V now
2326 displays APR's selection of the lock mechanism instead of the
2327 symbols previously respected by prefork. [Jeff Trawick]
2329 *) Change the mmap() feature test to check only for existence.
2330 The previous check required features not used by Apache.
2333 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2334 sometimes mangled. The len parm to accept() was not
2335 initialized, leading sometimes to an endless loop of failed
2336 accept() calls on OS/390 and anywhere else that failed the call
2337 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2338 instead of declaring it ourselves to fix a compilation problem
2339 on Solaris. [Jeff Trawick]
2341 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2343 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2345 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2347 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2348 initialization if ALLOC_DEBUG is defined; no known symptom
2349 otherwise. [Jeff Trawick]
2351 *) Fix typo in configure script when checking for mod_so. bash
2352 doesn't seem to have a problem but /bin/sh on Solaris does.
2353 Symptom: "./configure: test: unknown operator =="
2356 *) Rebind the Win32 NT and 9x services control into the MPM.
2357 All console, WinNT SCM and Win9x pseudo-service control code is
2358 now wrapped within the WinNT MPM.
2361 *) Make a copy of getenv("PATH") before storing for later use. Some
2362 getenv() implementations use the same storage for successive calls.
2363 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2365 *) Server Tokens work in 2.0 again. This also propogates the change
2366 to allow just the product name in the server string using
2370 Changes with Apache 2.0a4
2372 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2373 won't need to call it. [Greg Ames, Jeff Trawick]
2375 *) Move pre_config hook call to between configuration read and config
2376 tree walk. This allows all modules to implement pre_config hooks
2377 and know that they will be called at an appropriate time.
2380 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2383 *) Add pre-config hooks back to all modules.
2386 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2387 ContentDigest enabled and we can't/don't mmap the file.
2390 *) We now report the correct line number for syntax errors in config
2391 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2393 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2394 related bugs, and changed shmem/locking to use apr API. Shared-mem
2395 is currently disabled, however, because of problems with graceful
2396 restarts. [Ronald Tschalär]
2398 *) Fix corruption of IFS variable in --with-module= handling.
2399 Depending on the user's shell or customization thereof, there
2400 would be errors generating ap_config_auto.h later in the configure
2401 procedure. [Jeff Trawick]
2403 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2404 isn't used (as in 1.3), except that on Unix it is now logged via
2405 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2406 to the error log. [Greg Ames, Jeff Trawick]
2408 *) Add '-D' argument processing for run time configuration defines.
2411 *) Organize http_main.c as independent code, such that no code or
2412 global data is exported from it. WIN32 will dynamically link it
2413 to the server core, so this will prevent mutual dependency.
2416 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2417 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2420 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2421 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2423 *) Add mod_charset_lite for configuring character set translation.
2426 *) Add '-n' option to htpasswd to make it print its user:pw record
2427 on stdout rather than having to frob a text file. [Ken Coar]
2429 *) Fix saferead. Basically, we flush the output buffer if a read on the
2433 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2434 a conversion is single-byte only. [Jeff Trawick]
2436 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2437 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2440 *) Fix some minor errors where pid was being manipulated as an int
2441 instead of the portable pid_t. [Roy Fielding]
2443 *) Fix some error log prints that were printing the pointer to a
2444 structure rather than the pid within the structure.
2445 [Jeff Trawick, Roy Fielding]
2447 *) ab: Fix a command-line processing bug; track bad headers in
2448 err_response; support reading headers up to 2K.
2449 [Ask Bjoern Hansen <ask@valueclick.com>]
2451 *) Fix ap_resolve_env() so that it handles new function added in a prior
2452 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2453 config file.") as well as the constructs used by mod_rewrite.
2454 [Paul Reder <rederpj@raleigh.ibm.com>]
2456 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2458 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2459 APR to perform translation, instead of accessing the hard-coded tables
2460 in 1.3's ebcdic.c. [Jeff Trawick]
2462 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2465 *) Add the ability to hook into the config file reading phase. Basically
2466 if a directive is specified EXEC_ON_READ, then when that directive is
2467 read from the config file, the assocaited function is executed. This
2468 should only be used for those directives that must muck with HOW the
2469 server INTERPRETS the config. This should not be used for directives
2470 that re-order or replace items in the config tree. Those changes should
2471 be made in the pre-config step.
2474 *) Add mod_example to the build system.
2477 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2478 byte character sets. [Jeff Trawick]
2480 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2481 Kraemer and Oliver Reh originally according to the change log).
2484 *) Fix a couple of problems in RFC1413 support (controlled by the
2485 IdentityCheck directive). Apache did not build the request string
2486 properly and more importantly Apache would loop forever if the
2487 would-be ident server dropped the connection before sending a
2488 properly terminated response. [Jeff Trawick]
2490 *) apxs works in 2.0.
2493 *) Reliable piped logs work in 2.0.
2496 *) Introduce a hash table implementation into APR to be used for
2497 replacing tables and other random data structures in Apache.
2500 *) Add some more error reporting to htpasswd in the case of problems
2501 generating or accessing the temporary file. Also, pass in a
2502 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2503 is defined). [Ken Coar]
2505 *) Configure creates config.nice now containing your configure
2506 options. Syntax: ./config.nice [--more-options]
2509 *) Fix various return code problems in APR on Win32. For most of
2510 these, APR was returning APR_EEXIST instead of GetLastError()/
2511 WSAGetLastError(). [Jeff Trawick]
2513 *) Make piped logs work again in version 2.0
2516 *) Add VPATH support to UNIX build system of Apache and APR.
2519 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2523 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2524 Patch submitted to author.
2527 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2528 /sbin in PATH on FreeBSD (all submitted to rse previously)
2531 *) Fix building Pthread-based MPMs on OpenBSD
2532 [Sascha Schumann] PR#26
2534 *) Fix ap_readdir() problem on systems where d_name[] field in
2535 struct dirent is declared with only one byte. (This problem only
2536 affected multithreaded builds.) This caused a segfault during
2537 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2538 least). [Jeff Trawick]
2540 *) Fix some make-portability problems on at least Tru64, Irix
2542 [Sascha Schumann] PR#18, PR#39
2544 *) Add ap_sigwait() to support old-style sigwait() on systems
2545 like OS/390 and UnixWare.
2548 *) Add POSIX-thread flags for more platforms.
2551 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2552 (on Unix, at least) to handle resolver errors. Fix a bug in
2553 the definition of APR_ENOMEM so that ap_strerror() can spit
2554 out the correct error message for it.
2557 Changes with Apache 2.0a3
2559 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2562 *) API: *HOOK* macros now have an AP_ prefix
2565 *) Win32: Eliminate redundant calls to initialize winsock.
2566 [Tim Costello <timcostello@ozemail.com.au>]
2568 *) Fix bugs initializing ungetchar for pipes.
2569 [Chia-liang Kao <clkao@CirX.ORG>]
2571 *) The ab program in the src/support directory is now portable using
2575 *) Support directory is being compiled when the server is built
2578 *) The configure option --with-program-name has been added to allow
2579 developers to rename the executable at configure time. This also
2580 changes the name of the config files to match the executable's name.
2583 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2584 containing version numbers. [Martin Pool]
2586 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2587 Unix; access_log and error_log now created with these perms; non-
2588 Unix is unaffected [Jeff Trawick]
2590 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2591 Replaced more magic numbers with MD5_DIGESTSIZE.
2592 [William Rowe, Roy Fielding]
2594 *) Win32: Get mod_auth_digest compiling and added to the Windows
2595 build environment. Not tested and I'd be suprised if it
2596 actually works. [Bill Stoddard]
2598 *) Revamp the Win32 make environment. Makefiles have been removed and
2599 Apache.dsw created to bring together all the pieces. Create new file
2600 os/win32/BaseAddr.ref to define module base addresses (to prevent
2601 dll relocation at start-up).
2602 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2604 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2605 of the \015, \012, and \015\012 constants with macros.
2606 [Greg Ames <gregames@us.ibm.com>]
2608 *) Add ap_xlate_open() et al for translation of text between different
2609 character sets. The initial implementation requires iconv().
2612 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2613 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2615 *) CGI output is being timed out now.
2618 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2619 is used by the new apr file. There is no reason to create a new file
2620 with the same lifetime as the original file.
2623 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2624 module base addresses. This will help shooting seg faults
2625 in the field. [William Rowe <wrowe@lnd.com>]
2627 *) Update Apache on Windows documentation. Add new document
2628 describing how to compile Apache on Windows.
2629 [William Rowe <wrowe@lnd.com>]
2631 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2632 microseconds instead of seconds. Some storage leaks and other
2633 minor bugs in related code were fixed. [Jeff Trawick]
2635 *) Win32: First cut at getting mod_isapi working under 2.0
2636 [William Rowe <wrowe@lnd.com>]
2638 *) First stab at getting mod_auth_digest working under 2.0
2639 quick change summary:
2640 - moved the random byte generation (ap_generate_random_bytes) into APR
2641 - now uses ap_time_t
2642 - compiles and runs on linux
2644 [Brian Martin <bmartin@penguincomputing.com>]
2646 *) Win32: Move the space stripping of physical service names
2647 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2648 unresolved symbol. Add dependency checking to the
2649 CreateService call to ensure TCPIP and AFP (winsock) is started
2651 [William Rowe <wrowe@lnd.com>]
2653 *) Win32: Add code to perform latebinding on functions that may
2654 not exist on all levels of Windows where Apache runs. This
2655 is needed to allow Apache to start-up on Win95/98. All calls
2656 to non portable functions should be protected with
2657 ap_oslevel checks to prevent runtime segfaults.
2658 [William Rowe <wrowe@lnd.com>]
2660 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2662 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2664 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2665 This addresses PR 1623. Still need to address timing out runaway
2666 CGI scripts. [Bill Stoddard]
2668 *) Win32: Make ap_stat Windows 95/98 friendly
2669 [William Rowe <wrowe@lnd.com>]
2671 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2672 always fail. Need to initialise the dwOSVersionInfoSize member of the
2673 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2676 The patch also enhances ap_get_oslevel (and the associated enum) to
2677 handle selected service packs for NT4, and adds recognition for
2678 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2679 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2680 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2682 *) Get mod_rewrite building and running, and mod_status building for Win NT
2683 [Allan Edwards <ake@raleigh.ibm.com>]
2685 *) Patch to port mod_auth_db to the 2.0 api and also to support
2686 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2687 2.7.7. It should work with version 1 as well but I haven't tested it.
2688 [Brian Martin <bmartin@penguincomputing.com>]
2690 *) Get APR DSO code working under Windows. Includes cross platform
2692 [Tim.Costello@BTFinancialgroup.com]
2694 *) Fix some of the Windows APR time functions.
2697 *) FAQ changes related to tidying up historical documents on the web site.
2698 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2700 *) Move Windows DSO code into APR.
2703 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2704 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2705 at build time. At this point, the server will not compile on Windows because
2706 of the recent DSO commits. Fixing those next.
2707 [Bill Rowe & Bill Stoddard]
2709 *) Added error checking for file I/O APR routines.
2710 [Jon Travis <jtravis@covalent.net>]
2712 *) APR: Don't use the values of resolver error codes for the
2713 corresponding APR error codes. On Unix and Win32, return the
2714 proper APR error code after a resolver error. [Jeff Trawick]
2716 Changes with Apache 2.0a2
2718 *) Renamed the executable back to httpd on all platforms other
2722 *) Allow BeOS to survive restarts, log properly and a few
2723 small things it had problems with due to the way it setup
2724 users and groups. [David Reid]
2726 *) Get mod_rewrite working with APR locks
2727 [Paul Reder <rederpj@raleigh.ibm.com>]
2729 *) Actually remove the sempahore when the lock cleanup routine
2730 is called on BeOS. [David Reid]
2732 *) Clear hook registrations between reads of the config file.
2733 When DSOs are unloaded and re-loaded the old hook pointers may
2734 no longer be valid. This fix eliminates potential segfaults.
2735 [Allan Edwards <ake@raleigh.ibm.com>]
2737 *) Fix a problem with Sigfunc not being defined or bypassed
2738 if sigaction() wasn't found. [Jim Jagielski]
2740 *) Fix the locking mechanism on BSD variants. They now use fcntl
2741 locks. This allows the server to start and serve pages.
2744 *) First cut at getting the Win32 installer to work
2745 [William Rowe <wrowe@lnd.com>]
2747 *) Get htpasswd compiling under Windows
2748 [William Rowe <wrowe@lnd.com>]
2750 *) Change the log message for a bind() failure to show the
2751 interface and port number. [Jeff Trawick]
2753 *) Import the documentation from 1.3.12 and bring parts of it
2754 up-to-date with respect to the changes that have occurred
2758 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2759 now logged correctly on BeOS.
2762 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2763 Makefile.win includes the same user interface as the old
2765 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2767 *) Win32 exec now uses COMSPEC environment string for command
2768 shell path resolution.
2769 [William Rowe <wrowe@lnd.com>] PR#3715
2771 *) Win32: ap_connect() was not returning correct error condition
2773 [Allen Prescott <allen@clanprescott.com>]
2775 *) Win32: ap_open() was broken on Win9x because an NT-specific
2776 flag was passed to CreateFile. ap_puts() added an unnecessary
2778 [Jeff Trawick <trawick@us.ibm.com>]
2780 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2781 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2782 confusing ee/et name and made all extensions language/dialect
2783 rather than country reflecting. Changed example files to
2784 explicit reflect the ISO charset and added a few common
2785 ones to the example config [dirkx]
2787 *) Extend external module capability. To use this, you call
2788 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2791 *) Backported the various "default charset" fixes from 1.3.12,
2792 including the AddDefaultCharset directive. [Jim Jagielski]
2794 *) Added the capability to do ${ENVVAR} constructs in the
2795 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2796 it does this on a line by line basis; i.e. if the envvar
2797 expands to something with spaces you have to protect it
2798 by adding quotes around it (Unless of course you expect it
2799 to contains more than one argument. Alternatively you
2800 can compile it on a per token basis; which is what people
2801 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2802 hampers fancier hacks.
2803 [Dirk-Willem van Gulik]
2805 *) Changed the 'ErrorDocument' syntax in that it NO longer
2806 supports the asymetric
2808 ErrorDocument 301 "Some message
2810 Note the opening " quote, without a closing quote. It now
2811 has either the following syntaxes
2813 ErrorDocument XXX /local/uri
2814 ErrorDocument XXX http://valid/url
2815 ErrorDocument XXX "Some Message"
2817 The recognition heuristic is: if it has a space it
2818 is a message. If it has no spaces and starts with a /
2819 or is a valid URL then treat it that way. Otherwise it
2820 is assumed to be a message.
2822 This breaks backward compatibility but makes live a hell
2823 of a lot easier for GUI's and config file parsers.
2824 [Dirk-Willem van Gulik]
2826 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2827 syntax into a 'on' or 'off' syntax. As it currently is the
2828 only non nesting token which uses NO_ARGS and thus is an
2829 absolute pain for any config interface automation. This
2830 breaks backward compatibility. [Dirk-Willem van Gulik]
2832 *) Add ability to add external modules to the build process. This is
2833 done with --with-module=/path/to/module. Modules can only be added
2834 as static modules at this point.
2837 Changes with Apache 2.0a1
2839 *) Fix FreeBSD 3.3 core dump.
2840 Basically, ap_initialize() needs to get called before
2841 create_process(), since create_process() passes op_on structure
2842 to semop() to get a lock, but op_on isn't initialized until
2843 ap_initialize() calls setup_lock(). Here is a slight
2844 rearrangement to main() which calls ap_initialize() earlier...
2845 [Jeff Trawick <trawick@us.ibm.com>]
2847 *) Enable Apache to use sendfile/TransmitFile API
2848 [Bill Stoddard, David Reid, Paul Reder]
2850 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2854 *) Make file I/O and network I/O writev/sendv APIs consistent.
2855 Eliminate use of ap_iovec_t and use Posix struct iovec.
2856 Use seperate variable on ap_writev to set the number of iovecs
2857 passed in and number of bytes written.
2860 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2861 with ap_create_file_iol(). ap_create_file_iol() requires that
2862 the file be opened prior to the call using ap_open().
2865 *) Port mod_include and mod_cgi to 2.0
2866 [Paul Reder, Bill Stoddard]
2868 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2869 bytes_read/bytes_written is always valid (never -1). Plus
2870 some fixes to buff.c to correct problems introduced by the
2871 errno => ap_status_t changes a while back. Plus a fix to
2872 chunked encoding introduced right at the beginning of 2.0.
2875 *) Revamped UNIX build system to use autoconf and libtool.
2876 [Manoj Kasichainula, Sascha Schumann]
2878 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2880 *) More rigorous checking of Host: headers to fix security problems
2881 with mass name-based virtual hosting (whether using mod_rewrite
2882 or mod_vhost_alias).
2883 [Ben Hyde, Tony Finch]
2885 *) Add back support for UseCanonicalName in <Directory> containers.
2886 [Manoj Kasichainula]
2888 *) Added APLOG_STARTUP log type. This allows us to write an error
2889 message without any of the date and time information. As a part
2890 of this change, I also removed all of the calls to fprintf(stderr
2891 and replaced them with calls to ap_log_error using APLOG_STARTUP
2892 writing to stderr is no longer portable, because we don't direct
2893 stderr to the error log on all platforms.
2896 *) Convert error logging functions to take errno as an argument.
2897 This makes our error logs more portable, because some Windows API's
2898 don't set errno. This change allows us to still output a valid
2899 message on all of our platforms.
2902 *) mod_mime_magic runs in 2.0-dev now.
2903 [Paul Reder <rederpj@raleigh.ibm.com>]
2905 *) sendfile has been added to APR.
2906 [John Zedlewski <zedlwski@Princeton.EDU>]
2908 *) buff.c has been converted to no longer use errno.
2909 [Manoj Kasichainula]
2911 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2912 interface adaption to APR functions did it. [Martin Kraemer]
2914 *) Support DSOs properly on 32-bit HP-UX 11.0
2915 [Dilip Khandekar <dilip@cup.hp.com>]
2917 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2918 [Ralf S. Engelschall]
2920 *) Cleaned APR build environment integration and bootstrap APR
2921 automatically for developers from src/Configure.
2922 [Ralf S. Engelschall]
2924 *) Fixed building of src/support/htpasswd.c
2925 [Ralf S. Engelschall]
2927 *) When generating the Location: header, mod_speling forgot
2928 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2931 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2933 *) Change all pools to APR contexts. This is the first step to
2934 incorporating APR into Apache. [Ryan Bloom]
2936 *) Move "handler not found" warning message to below the check
2937 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2938 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2940 *) Support line-continuation feature in config.option file and
2941 allow the loading of multiple option sections at once via
2942 ``--with-option=<section1>,<section2>,...''
2943 [Ralf S. Engelschall]
2945 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2947 Changes with Apache MPM
2949 *) Use asynchronous AcceptEx() and a completion port to accept and
2950 dispatch connections to threads in Windows NT/2000.
2953 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2956 *) Implement the APACI --with-option facility
2957 (per default used the config.option file).
2958 [Ralf S. Engelschall]
2960 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2962 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2963 Replace pre_connection module call with a register_hook call and
2964 implement pre_connection as a hook. The intent is that these hooks will
2965 be extended to allow Apache to be multi-protocol, and also to allow the
2966 calling order to be specified on a per-hook/per-module basis.
2969 *) Implement mpm_* methods as "modules". Each method gets its own
2970 subdir in src/modules (eg: src/modules/prefork). Selection
2971 of method uses Rule MPM_METHOD. [Jim Jagielski]
2973 *) Port the hybrid server from the apache-apr repository as
2974 mpm_mpmt_pthread. [Manoj Kasichainula]
2976 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2977 amongst the unix MPMs.
2979 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2980 signal handling for the new world order. [Dean Gaudet]
2982 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2983 of alloc.c for now. [Dean Gaudet]
2985 *) Handle partial large writes correctly. [Ben Laurie]
2987 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2988 based on IP/port. [Ben Laurie]
2990 *) Port a bunch of modules to the new module structure.
2991 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2993 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2995 *) Basic restructuring to introduce the MPM concept; includes various
2996 changes to the module API... better described by
2997 docs/initial_blurb.txt. [Dean Gaudet]
2999 Changes with Apache pthreads
3001 *) New buff option added: BO_TIMEOUT. It describes the timeout for
3002 buff operations (generally over a network).
3003 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
3005 *) Created http_accept abstraction. Added 4 new functions (not exported):
3006 init_accept(), begin_accepting_requests(), get_request(),
3007 stop_accepting_requests() [Bill Stoddard]
3009 *) Fix to ap_rprintf call that allows mod_info to work properly.
3010 [James Morris <jmorris@intercode.com.au>]
3012 *) user and ap_auth_type fields were moved from connection_rec to
3013 request_rec. [Ryan Bloom]
3015 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
3016 needed in a threaded server.
3018 *) Initial pthread implementation from from Dean's apache-nspr code.
3019 [Bill Stoddard, Ryan Bloom]
3022 Changes with Apache 1.3.9
3024 *) Remove bogus error message when a redirect doesn't set Location.
3025 Instead, use an empty string to avoid coredump if the error message
3026 was supposed to include a location. [Roy Fielding]
3028 *) Don't allow configure to include mod_auth_digest unless it is
3029 explicitly requested, even if the user asked for all modules.
3032 *) Translate module names to dll names for OS/2 so that they are no more
3033 than 8 characters long and have an extension of "dll" instead of "so".
3036 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
3037 Fix test-compile check to check for randbyte instead of trand32.
3038 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
3039 and tweak to make Amaya happier. [Ronald Tschalär]
3041 *) Ensure that the installed expat include files are world readable,
3042 just like the other header files. [Martin Kraemer]
3044 *) Fixed generated AddModule adjustments in APACI's `configure' script
3045 in order to allow (new) modules like mod_vhost_alias to be handled
3046 correctly (which was touched by the adjustments for mod_alias).
3047 [Ralf S. Engelschall]
3049 *) For binary builds, add -R flag to apachectl to work around the lack of
3050 an absolute path to the ./libexec directory where the libhttp.ep file
3051 is needed for SHARED_CORE architectures. [Randy Terbush]
3053 *) WIN32: Create the CGI script process as DETACHED. This may solve the
3054 problem observed by some Win95/98 users where they get CGI script
3055 output sent to the console. [Bill Stoddard]
3057 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
3058 routines are now called ap_base64* and are 'plain' (i.e., no
3059 pool access or anything clever). Inside util.c the routines acting
3060 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
3061 The oddly named ap_uuencode(), ap_uudecode() are kept around for
3062 now but deprecated. [dirkx]
3064 *) Clean up the base64 and SHA1 additions and make sure they are
3065 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
3066 files. [Roy Fielding]
3068 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
3069 checking. Allow compiling on VS 6.0. [Randy Terbush]
3071 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
3073 *) Use TestCompile to search for the truerand library (rather than blindly
3074 assuming its existence). If it is not found, complain (but do not
3075 exit - yet). [Martin Kraemer]
3077 *) We forgot to add the new exported function names to
3078 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
3080 *) Add description of -T command-line option to usage().
3081 [Ralf S. Engelschall]
3083 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
3084 searched only AFTER libap has been searched, because libap needs
3085 some symbols from libos. [Martin Kraemer]
3087 *) Fix conflict with original mod_digest related to the symbol of the
3088 module dispatch list (which has to be unique for DSO and follow the
3089 usual conventions for the installation procedure).
3090 [Ralf S. Engelschall]
3092 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
3093 for other platforms as well. [Martin Kraemer]
3095 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
3096 types by AP_LONG and replace reference to renamed variable 'ubuf'
3097 by 'buffer'. [Martin Kraemer]
3099 Changes with Apache 1.3.8 [not released]
3101 *) Flush the output buffer immediately after sending an error or redirect
3102 response, since the result may be needed by the client to abort a
3103 long data transfer or restart a series of pipelined requests.
3104 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
3106 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
3107 [Ian Turner <iant@sequent.com>] PR#4735
3109 *) Local struct mmap in http_core.c conflicted with system structure
3110 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
3112 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
3113 [Ronald Tschalär <ronald@innovation.ch>]
3115 *) Fix a memory leak where the module counts were getting messed
3116 up across restarts. [David Harris <dharris@drh.net>]
3118 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
3119 properly in mod_access.
3120 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
3122 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
3123 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
3125 *) PORT: Support for compaq/tandem/com.
3126 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
3128 *) Added SHA1 password encryption support to easy migration from
3129 Netscape servers. See support/SHA1 for more information.
3130 Caused the separation of ap_md5.c into md5, sha1 and a general
3131 ap_checkpass.c with just a validate_passwd routine. Added a
3132 couple of flags to support/htpasswd. Some reuse of the to64()
3133 function; hence renamed to ap_to64().
3134 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
3136 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
3137 with ASCII/EBCDIC conversions in "ident" query.
3138 [David McCreedy <McCreedy@us.ibm.com>]
3140 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
3141 Change "Power Macintosh" to Power* so if uname prints "Power Book"
3142 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
3144 *) Fix SIGSEGV on some systems because the Vary fix below included
3145 a call to table_do with a variable argument list that was not
3146 NULL terminated. Replaced with better implementation. [Roy Fielding]
3148 Changes with Apache 1.3.7 [not released]
3150 *) The "Vary" response header field is now sanitised right before
3151 the header is sent back to the client. Multiple "Vary" fields
3152 are combined, and duplicate tokens (e.g., "Vary: host, host" or
3153 "Vary: host, negotiate, host, accept-language") are reduced to
3154 single instances. This is a better solution than the force-no-vary
3155 one (which is still valid for clients that can't cope with Vary
3156 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
3158 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
3160 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
3161 least on Linux and FreeBSD for now.
3164 *) Win32: More apache -k restart work. Restarts are now honored
3165 immediately and connections in the listen queue are -not- lost.
3166 This is made possible by the use of the WSADuplicateSocket()
3167 call. The listeners are opened in the parent, duplicated, then
3168 the duplicates are passed to the child. The original listen sockets
3169 are not closed by the parent across a restart, thus the listen queue
3171 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3173 *) Fix handling of case when a client has sent "Expect: 100-continue"
3174 and we are going to respond with an error, but get stuck waiting to
3175 discard the body in the pointless hope of preserving the connection.
3176 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
3178 *) Fix 'configure' to work correctly with SysV-based versions of
3179 'tr' (consistent with Configure's use as well). [Jim Jagielski]
3181 *) apxs: Add "-S var=val" option which allows for override of CFG_*
3182 built-in values. Add "-e" option which works like -i but doesn't
3183 install the DSO; useful for editing httpd.conf with apxs. Fix
3184 editing code so that multiple invocations of apxs -a will not
3185 create duplicate LoadModule/AddModule entries; apxs can now be
3186 used to re- enable/disable a module. [Wilfredo Sanchez]
3188 *) Win32: Update the server to use Winsock 2. Specifically, link with
3189 ws2_32.lib rather than wsock32.lib. This gives us access to
3190 WSADuplcateSocket() in addition to some other enhanced comm APIs.
3191 Win 95 users may need to update their TCP/IP stack to pick up
3192 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
3193 [Bill Stoddard stoddard@raleigh.ibm.com]
3195 *) Win32: Redirect CGI script stderr (script debug info) into the
3196 error.log when CGI scripts fail. This makes Apache on Win32
3197 behave more like Unix.
3198 [Bill Stoddard stoddard@raleigh.ibm.com]
3200 *) Fixed `httpd' usage display: -D was missing.
3201 [Ralf S. Engelschall] PR#4614
3203 *) Fix `make r' test procedure in src/regex/: ap_isprint was not found.
3204 [Ralf S. Engelschall] PR#4561, PR#4562
3206 *) OS/2: Fix problem with accept lock semaphores where server would die with
3207 "OS2SEM: Error 105 getting accept lock. Exiting!"
3208 [Brian Havard] PR#4505
3210 *) Add DSO support for DGUX 4.x using gcc. Tested on x86 platforms.
3211 [Randy Terbush <randy@covalent.net>]
3213 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
3214 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3216 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3217 command potentially _is_ GCC. [Ralf S. Engelschall]
3219 *) Fix apxs build issues on AIX
3220 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3222 *) DocumentRoot Checking: Under previous versions, when Apache
3223 first started up, it used to do a stat of each DocumentRoot to
3224 see if it existed and was a directory. If not, then an error
3225 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3226 does not exist, you will get error messages in error_log. If
3227 the '-t' command line option is used (to check the configuration)
3228 the check of DocumentRoot IS performed. An additional command
3229 line option, '-T', has been added if you want to avoid the
3230 DocumentRoot check even when checking the configuration.
3233 *) Win32: The query switch "apache -S" didn't exit after showing the
3234 vhost settings. That was inconsistent with the other query functions.
3235 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3237 *) Win32: Changed behaviour of apache -k restart.
3238 Previously, the server would drain all connections in the stack's
3239 listen queue before honoring the restart. On a busy server, this
3240 could take hours. Now, a restart is honored almost immediately.
3241 All connections in Apache's queues are handled but connections in
3242 the stack's listen queue are discarded. Restart triggered by
3243 MaxRequestPerChild is unchanged.
3244 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3246 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3247 the accept loop. Good for a 5% performance boost. Cleaned up
3248 parent/child process management code.
3249 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3251 *) Added ceiling on file size for memory mapped files.
3252 [John Giannandrea <jg@meer.net>] PR#4122
3254 *) Fix ndbm.h include problems with brain-dead glibc >= 2.1 which
3255 has ndbm.h in a non-standard db1/ subdir. PR#4431, PR#4528
3256 [Henri Gomez <gomez@slib.fr>, Ralf S. Engelschall]
3258 *) Determine AP_BYTE_ORDER for ap_config_auto.h and already
3259 use this at least for Expat. [Ralf S. Engelschall]
3261 *) Allow .module files to specify libraries with Lib:.
3264 *) Allow SetEnvIf[NoCase] to test environment variables as well
3265 as header fields and request attributes. [Ken Coar]
3267 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3268 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3270 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3271 never accepted into any standard, and it opens up certain DoS
3272 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3274 *) TestCompile updated. We can now run programs and output the
3275 results during the Configure process. [ Jim Jagielski]
3277 *) The source is now quad (long long) aware as needed. Specifically,
3278 the Configure process determines the correct size of off_t and
3279 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3280 provides for the 'q' format qualifier (if quads are not available,
3281 'q' is silently "demoted" to long). [Jim Jagielski]
3283 *) When the username or password fed to htpasswd is too long, include the
3284 size limit in the error message. Also report illegal characters
3285 (currently only ':') in the username. Add the size restrictions
3286 to the man page. [Ken Coar]
3288 *) Fixed the configure --without-support option so it doesn't result in
3289 an infinite loop. [Marc Slemko]
3291 *) Piped error logs could cause a segfault if an error occured
3292 during configuration after a restart.
3293 [Aidan Cully <aidan@panix.com>] PR#4456
3295 *) If a "Location" field was stored in r->err_headers_out rather
3296 than r->headers_out, redirect processing wouldn't find it and
3297 the server would core dump on ap_escape_html(NULL). Check both
3298 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3299 if Location isn't set. [Doug MacEachern, Ken Coar]
3301 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3302 of the Expat 1.0.2 distribution. [Greg Stein]
3304 *) Replace regexec() calls with calls to a new API stub function
3305 ap_regexec(). This solves problems with DSO modules which use the regex
3306 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3308 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3309 environment variables can be set according to the protocol version
3310 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3312 *) Add DSO support for OpenStep (Mach 4.2) platform.
3313 [Ralf S. Engelschall, Rex Dieter <rdieter@math.unl.edu>] PR#3997
3315 *) Fix sed regex for generating ap_config_auto.h in src/Configure.
3316 [Jan Gallo <gallo@pvt.sk>] PR#3690, PR#4373
3318 *) Switch to /bin/sh5 in APACI on Ultrix and friends to avoid problems with
3319 their brain-dead /bin/sh. [Ralf S. Engelschall] PR#4372
3321 *) Better DSO flags recognition on NetBSD platforms using ELF.
3322 [Todd Vierling <tv@pobox.com>] PR#4310
3324 *) Always log months in english format for %t in mod_log_config.
3325 [Petr Lampa <lampa@fee.vutbr.cz>] PR#4366, 679
3327 *) Support for server-parsed and multiview-determined ReadmeName and
3328 HeaderName files in mod_autoindex. Removed the restriction on
3329 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3330 routines will deal with the access issues. (It's now possible to
3331 have {site|group|project|customer|...} wide readmes and headers.)
3332 [Raymond S Brand <rsbx@rsbx.net>, Ken Coar] PR#1574, 3026, 3529,
3335 *) When stat() fails, don't assume anything about the contents of
3336 the struct stat. [Ed Korthof <ed@bitmechanic.com>]
3338 *) It's OK for a semop to return EINTR, just loop around and try
3339 again. [Dean Gaudet]
3341 *) Fix configuration engine re-entrant hangups, which solve a
3342 handful of problems seen with mod_perl <Perl> configuration sections
3343 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3345 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3346 by default when building with APACI; allow for platform-specific
3347 variable defaults in configure. [Wilfredo Sanchez]
3349 *) Do setgid() before initgroups() in http_main; some platforms
3350 zap the grouplist when setgid() is called. This was fixed in
3351 suexec earlier, but the main httpd code missed the change.
3352 [Rob Saccoccio <robs@InfiniteTechnology.com>] PR#2579
3354 *) Add recognition of .tgz as a gzipped tarchive.
3355 [Bertrand de Singly <bertrand.de-singly@polytechnique.fr>] PR#2364
3357 *) mod_include's fsize/flastmod should allow only relative paths, just
3358 like "include file". [Jaroslav Benkovsky <benkovsk@pha.pvt.cz>]
3360 *) OS/2: Add support for building loadable modules using DLLs.
3363 *) Add iconsdir, htdocsdir, and cgidir to config.layout.
3366 *) Fix minor but annoying bug with the test for Configuration.tmpl
3367 being newer than Configuration so that it is less likely to fail
3368 when using APACI and shadow sources. [Wilfredo Sanchez]
3370 *) PORT: Add initial support for Mac OS (versions 10.0 and
3371 greater). Use Mac OS X Server layout for now. Clean up dyld code
3372 in unix/os.c, and don't install the dyld error handlers, which
3373 are no longer needed in Mac OS. [Wilfredo Sanchez]
3375 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3376 locations to appropriate ones for user-built (as opposed to
3377 system) installs. [Wilfredo Sanchez]
3379 *) Modify mod_autoindex's handling of AddDescription so that the
3380 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3382 *) Add functionality to the install-bindist.sh script created by
3383 binbuild.sh to use tar when copying distribution files to the
3384 serverroot. This allows upgrading an existing installation
3385 without nesting the new distribution in the old.
3387 install-bindist.sh now detects the local perl5 path to install
3388 apxs and dbmmanage with proper path to perl interpreter.
3390 Add an install-binsupport target which copies the source files
3391 for apxs and dbmmanage to bindist to allow these scripts to
3392 be properly installed relative to the destination serverroot.
3393 [Randy Terbush, Covalent Technologies, randy@covalent.net]
3395 *) Fix intermittent SEGV in ap_proxy_cache_error() in
3396 src/modules/proxy_util.c where a NULL filepointer and

3404 *) OS/2: Fix terminating CGIs that aren't compiled by EMX GCC when a
3405 connection is aborted. [Brian Havard]
3407 *) Force the LANG envariable to the known state of "C" so that we
3408 have assurance about how string manipulators (e.g., tr) will
3409 function. [Ken Coar] PR#1630
3411 *) Add a directive to allow customising of the tracking cookie name.
3412 [Ken Coar] PR#2921, 4303
3414 *) Add "force-no-vary" envariable to allow servers to work around
3415 clients that choke on "Vary" fields in the response header.
3416 [Ken Coar, Dmitry Khrustalev <dima@zippy.machaon.ru>] PR#4118
3418 *) Fixed a bug in mod_dir that causes a child process will infinitely
3419 recurse when it attemps to handle a request for a directory wnd the
3420 value of the DirectoryIndex directive is a single dot. Also likely
3421 to happen for anyother values of DirectoryIndex that will map back

3432 *) Add "opt" (SysV-style) layout to config.layout. [Raymond S Brand
3435 *) Add APACI --without-execstrip option which can be used to disable the
3436 stripping of executables on installation. This is very important for DSO
3437 and debugging situations. [Ralf S. Engelschall]
3439 *) Add support for OS/2 (case insenstive filesystem, .exe suffix, etc)

3505 *) Make {Set,Unset,Pass}Env per-directory instead of per-server.
3508 *) Correct an apparent typo: on the Windows and MPE platforms, the
3509 htpasswd utility was limiting passwords to only 8 characters.
3512 *) EBCDIC platforms: David submitted patches for two bugs in the
3513 MD5 digest port for EBCDIC machines:
3514 a) the htdigest utility overwrote the old contents of the digest file
3515 b) the Content-MD5 header value (ContentDigest directive) was wrong
3516 when the returned file was not converted from EBCDIC, but was a
3517 binary (e.g., image file) in the first place.
3518 [David McCreedy <mccreedy@us.ibm.com>]
3520 *) support/htpasswd now permits the password to be specified on the
3521 command line with the '-b' switch. This is useful when passwords
3522 need to be maintained by scripts -- particularly in the Win32
3523 environment. [Ken Coar]
3525 *) Win32: Win32 multiple services patch. Added capability to install and
3526 run multiple copies of apache as individual services.
3529 apache -n apache1 -i -f c:/httpd.conf

3551 Restart apache2 service
3553 [Keith Wannamaker, Ken Parzygnat, Bill Stoddard]
3555 *) Correct the signed/unsigned character handling for the MD5 routines;
3556 mismatches were causing compilation problems with gcc -pedantic and
3557 in the TPF cross-compilation. [Ken Coar]
3559 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3560 a roughly 5 fold speed up. [Brian Havard]
3562 *) proxy ftp: instead of using the hardwired string "text/plain" as
3563 a fallback type for files served by the ftp proxy, use the
3564 ap_default_type() function to determine the configured type.
3565 This allows for special configurations like
3566 <Directory proxy:ftp://some.host>
3567 DefaultType gargle/blurb
3569 Additionally, add the Content-Encoding: header to FTP proxy replies
3570 when the encoding is defined (by the AddEncoding directive).
3571 Because it was missing, it was almost impossible to browse compressed
3572 files using the FTP proxy (works now perfectly in Communicator).
3573 The ftp proxy now also returns the Date: and Server: header lines (if not
3574 much else... This code is "somewhat" broken) like normal requests do.
3577 *) Be more smart in APACI's configure script when determining the UID/GID
3578 for User/Group directives and use the determined UID/GID to initialize
3579 the permissions on the proxycachedir.
3580 [Dirk-Willem van Gulik, Ralf S. Engelschall]
3582 *) Changed the forking-prior-to-cleanup in the proxy module to first
3583 check wether it actually needs to collect garbage. This reduces
3584 the number of fork()s from one/request to just the odd one an hour.
3585 [Dirk-Willem van Gulik]
3587 *) Added proxy, auth and header support to src/support/ab.c. Added a

3595 [Randy Terbush, Covalent Technologies]
3597 *) Fix sed-substitutions in `make install': path elements like `httpd/conf'
3598 (for instance from an APACI configure --sysconfdir=/etc/httpd/conf

3608 Changes with Apache 1.3.6
3610 *) Removed new PassAllEnv code due to DSO problems. [Lars Eilebrecht]
3612 Changes with Apache 1.3.5 [not released]
3614 *) M_INVALID needed a value within the scope of METHODS so that unknown
3615 methods can be access controlled. [Roy Fielding] PR#3821
3617 *) Added PassAllEnv; makes server's entire environment available
3618 to CGIs and SSIs executed within directive's scope. [Ken Coar]
3620 *) ap_uuencode() always added two trailing '='s and encoding of
3621 8 bit characters on a machine with signed char may produced
3622 incorrect results. Additionally ap_uuencode() should now
3623 work correctly on EBCDIC platforms.
3624 [Ronald Tschalär <ronald@innovation.ch>] PR#3411
3626 *) WIN32: Binary installer now runs the configuration DLL before
3627 the reboot prompt (which is only given if MSVCRT.DLL system
3628 DLL is new or updated). This should avoid the configuration
3629 directory being empty after installation. [Paul Sutton]
3630 PR#3767, 3800, 3827, 3850, 3900, 3953, 3988

3634 the Apache service on NT. [Paul Sutton] PR#3741
3636 *) WIN32: Apache.exe now contains an icon. [Paul Sutton]
3638 *) PORT: Switch back to using fcntl() locking on Linux -- instabilities
3639 have been reported with flock() locking (probably related to kernel
3640 version). [Dean Gaudet] PR#2723, 3531
3642 *) Using APACI, the main config file (usually httpd.conf) was
3643 not being adjusted as $(TARGET).conf. [Wilfredo Sanchez

3653 *) ap_isxdigit was somehow neglected when adding the ap_isfoo() macros
3654 for 8-bit safeness. [Dean Gaudet]
3656 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3657 because SPARCs have a small machine-specific maximum size for the Global
3658 Offset Table which is often exceeded when compiling one of the larger
3659 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3661 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the
3662 DSO/DLL section because it's a directive from mod_status and isn't
3663 available before the DLL of mod_status is loaded.

3678 *) Let APACI's configure script correctly complain for unknown --enable-XXX
3679 and --disable-XXX options. [Ralf S. Engelschall] PR#3958
3681 *) Link the shared core bootstrap program (``Rule SHARED_CORE=yes'') also
3682 against libap.a and use its ap_snprintf() instead of sprintf() to avoid
3683 possible buffer overflows. [Ralf S. Engelschall]
3685 *) Remove no longer used non-API function ap_single_module_init().
3686 [Ralf S. Engelschall]
3688 *) Add Apple's Mac OS X Server Layout "Rhapsody" to config.layout.
3691 *) Add cgidir, htdocsdir, iconsdir variables to Makefile.tmpl in order
3692 to make platform installations easier. [Wilfredo Sanchez]
3694 *) In configure, do not append the target name to the directory path if
3695 the path already contains "apache". [Ralf S. Engelschall]
3697 *) SIGPIPE is now ignored by the server core. The request write routines
3698 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3699 correctly check for output errors and mark the connection as aborted.
3700 Replaced many direct (unchecked) calls to ap_b* routines with the
3701 analogous ap_r* calls. [Roy Fielding]
3703 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3704 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3705 Furthermore map lookups for non-existent keys are now cached as well.
3706 Additionally "txt" maps are now parsed with simple string functions
3707 instead of using ap_pregcomp(). As a side effect a bug that prevented
3708 the usage of keys containing the "," character was fixed.
3709 The changes drastically improve the performance when large rewrite maps
3711 [Michael van Elst <mlelstv@serpens.swb.de>, Lars Eilebrecht] PR#3160
3713 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
3714 other than GET, and const'd the definition of method in request_rec.
3717 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
3719 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3720 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3722 *) Add %V to mod_log_config, this logs the hostname according to the
3723 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3724 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3726 *) Add support for \n and \t to mod_log_config, can be used to produce
3727 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3729 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]
3731 *) Added informative error messages for failed munmap() and fseek() calls
3732 in http_core.c. [John Bley, Roy Fielding]
3734 *) Added some informative error messages for some failed malloc()
3735 calls. [John Bley <jbb6@acpub.duke.edu>, Jim Jagielski]
3737 *) OS/2 ap_os_canonical_filename()'s behaviour is improved: ap_assert()
3738 is removed. This allows <Directory proxy:*> directives to work and
3739 prevents invalid requests from killing the process.
3740 [Brian Havard <brianh@kheldar.apana.org.au>]
3742 *) Reorganised FAQ document.
3743 [Joshua Slive <slive@finance.commerce.ubc.ca>] PR#2497
3745 *) src/support/: The ApacheBench benchmark program was overhauled by
3746 David N. Welton: you can now have it generate an HTML TABLE, presumably
3747 for integration into other HTML sources. David updated the ab man page
3748 as well and added some missing descriptions. Thanks!
3749 [David N. Welton <davidw@prosa.it>]
3751 *) Win32: The filename validity checker now allows filenames containing
3752 characters in the range 0x80 to 0xff (for example accented characters).
3753 [Paul Sutton] PR#3890
3755 *) Added conditional logging based upon environment variables to
3756 mod_log_config. mod_log_referer and mod_log_agent
3757 are now deprecated. [Ken Coar]
3759 *) Allow apache acting as a proxy server to relay the real
3760 reason of a failure to a client rather than the "internal
3761 server error" it does currently. The general exposure mechanism
3762 can be triggered by any module by setting the "verbose-error-to"
3763 note to "*"; this allows more than just proxy errors to be exposed.
3764 [Cliff Skolnick, Roy Fielding, Martin Kraemer] Related to PR#3455, 4086
3766 *) Moved man pages for ab and apachectrl to section 8.
3767 [Wilfredo Sanchez, Roy Fielding]
3769 *) Added -S option to install.sh so that options can be passed to
3770 strip on some platforms. [Ralf S. Engelschall, Wilfredo Sanchez]
3772 *) Tweak modules Makefile generated by Configure so that it handles
3773 the test case of no modules being selected. [chaz@reliant.com]
3775 *) Added a <LimitExcept method ...> sectioning directive that allows
3776 the user to assign authentication control to any HTTP method that
3777 is *not* given in the argument list; i.e., the logical negation
3778 of the <Limit> directive. This is particularly useful for controlling
3779 access on methods unknown to the Apache core, but perhaps known by
3780 some module or CGI script. [Roy Fielding, Tony Finch]
3782 *) Prevent apachectl from complaining if the PIDFILE exists but
3783 does not contain a process id, as might occur if the server is
3784 being rapidly restarted. [Wilfredo Sanchez]
3786 *) Win32: Add global symbols missing from ApacheCore.def. [Carl Olsen]
3788 *) Entity tag comparisons for If-Match and If-None-Match were not being
3789 performed correctly -- weak tags might cause false positives. Also,
3790 strong comparison wasn't properly enforced in all cases.
3791 [Roy Fielding, Ken Coar, Dean Gaudet] PR#2065, 3657
3793 *) OS/2: Supply OS/2 error code instead of errno on semaphore errors.
3796 *) Work around a bug in Lynx regarding its sending "Negotiate: trans"
3797 even though it doesn't understand TCN. [Koen Holtman, Roy Fielding]
3799 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3800 to util.c for parsing an HTTP header field value to extract the next
3801 list item, taking into account the possible presence of nested comments,
3802 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3803 insignificant whitespace and lowercases non-quoted tokens.
3804 [Roy Fielding] PR#2065
3806 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3807 code different from 500. This allows the proxy to, e.g., return
3808 "403 Forbidden" for ProxyBlock'ed URL's. [Martin Kraemer] Related to PR#3455
3810 *) Fix ordering of language variants for the case where the traditional
3811 negotiation algorithm is being used with multiple language variants
3812 and no Accept-Language. [James Treacy <treacy@debian.org>] PR#3299, 3688
3814 *) Do not round the TCN quality calculation to 5 decimal places,
3815 unlike RFC 2296, because the calculation might need 12 decimal places
3816 to get the right result. [Roy Fielding]
3818 *) Remove unused code to disable transparent negotiation when
3819 negotiating on encoding only, as we now handle encoding too
3820 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3821 fiddle from the fiddle-averse RVSA comparison, and fix bugs in
3822 some debugging statements within mod_negotiation. [Koen Holtman]
3824 *) Fixed a rare memory corruption possibility in mod_dir if the index
3825 file is negotiable and no acceptable variant can be found.
3826 [Dean Gaudet, Roy Fielding, Martin Kraemer]
3828 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3829 searching the Win32 registry for script interpreters.
3832 *) Win32: The compiled-in default filename for the error log is now
3833 error.log, which matches the default in the distributed httpd.conf.
3836 *) Win32: Any error messages from -i or -u command line options are now
3837 displayed on the console output rather than sent to the error log.
3838 Also the "Running Apache..." message is not output unless Apache is
3839 going to serve requests. [Paul Sutton]
3841 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3842 and use a private significator ('$apr1$') to mark passwords as
3843 being smashed with our own algorithm. Also abstract the password
3844 checking into a new ap_validate_password() routine. [Ken Coar]
3846 *) Win32: The filename validity checker now allows "COM" but refuses
3847 access to "COM1" through "COM4". This allows filenames such
3848 as "com.name" to be served. [Paul Sutton] PR#3769.
3850 *) BS2000: Adapt to the new ufork() system call interface which will
3851 make subtasking easier on the OSD/POSIX mainframe environment.
3854 *) Add a compatibility define for escape_uri() -> ap_escape_uri() to
3855 ap_compat.h. [David White <david@persimmon.com>] PR#3725
3857 *) Make NDBM file suffix determination for mod_rewrite more accurate, i.e.
3858 use `.db' instead of `.pag' not only for FreeBSD, but also when
3859 the NDBM library looks like Berkeley-DB based.
3860 [Ralf S. Engelschall] PR#3773
3862 *) Add ability to handle DES or MD5 authentication passwords.
3863 [Ryan Bloom <rbb@Raleigh.IBM.Com>]
3865 *) Fix O(n^2) memory consumption in mod_speling. [Dean Gaudet]
3867 *) SECURITY: Avoid some buffer overflow problems when escaping
3868 quoted strings. (This overflow was on the heap and we believe
3869 impossible to exploit.) [Rick Perry <perry@ece.vill.edu>]
3871 *) Let src/Configure be aware of CFLAGS options starting with plus
3872 signs as it's the case for the HP/UX compiler.
3873 [Doug Yatcilla <yatcilda@umdnj.edu>] PR#3681
3875 *) Remove the hard-wire of TAR=tar (we now check for gtar and gnutar first)
3876 and check to see if the tar we wind up with supports '-h'.
3877 [Jim Jagielski] PR#3671
3879 *) A consistent and conservative style for all shell scripts has been
3880 implemented. Basically, all shell string tests use the traditional
3881 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3882 to protect against bare null variable strings (ie: wrapping both
3883 sides with double quotes and prepending 'x'). 'x' was chosen
3884 because it's more universal and hopefully easier for old shell
3885 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3888 *) The status module now prints out both the main server generation as
3889 well as the generation of each process. Also, the vhost info is
3890 printed with '?notable'. [Jim Jagielski]
3892 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3893 and this makes its functions available to things in src/support.
3896 Changes with Apache 1.3.4
3898 *) Renamed macros status_drops_connection to ap_status_drops_connection
3899 and vestigial scan_script_header to ap_scan_script_header_err,
3900 mostly for aesthetic reasons. [Roy Fielding]
3902 *) The query switch "httpd -S" didn't exit after showing the
3903 vhost settings. That was inconsistent with the other query functions.
3906 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3907 filename to the end of the STANDARD_MODULE_STUFF. Its
3908 presence at the beginning prevented reporting of the filename
3909 for modules compiled before 1 January 1999. [Ken Coar]
3911 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3912 to detect and prevent access to special DOS device file names.
3913 [Paul Sutton, Ken Parzygnat]
3915 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3916 and Makefile_win32_debug.txt (debug build) that work on Win95.
3917 Run each of the following from the src directory:
3918 nmake /f Makefile_win32.txt # compiles normal build
3919 nmake /f Makefile_win32.txt install # compiles and installs
3920 nmake /f Makefile_win32.txt clean # removes compiled junk

3922 nmake /f Makefile_win32_debug.txt install
3923 nmake /f Makefile_win32_debug.txt clean
3926 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3927 to build binary distributions. [Lars Eilebrecht]
3929 *) IndexOptions SuppressColumnSorting only turned off making
3930 the column headers anchors; you could still change the display
3931 order by manually adding a '?N=A' or similar query string to the
3932 URL. Now SuppressColumnSorting locks in the sort order so
3933 it can't be overridden this way. [Ken Coar]
3935 *) Added IndexOrderDefault directive to supply a default sort order
3936 for FancyIndexed directory listings. [Ken Coar] PR#1699
3938 *) Change the ap_assert macro to a variant that works on all platforms.
3939 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3941 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3942 search for an underscore on dlsym() (as it's already the case
3943 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3945 *) Small fix for mod_env.html: The module was documented as to be _not_
3946 compiled into Apache per default, although it _IS_ compiled into
3947 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3949 *) Instead of fixing a bug in the generation procedure for config.status (a
3950 backslash was missing) we remove the bug together with it's complete
3951 context because the special cases of the past can now no longer occur
3952 because of the recent magic for the --with-layout default.
3953 [Ralf S. Engelschall] PR#3590

3957 depend on other libraries).
3958 [Markus Theissinger <markus.theissinger@gmx.de>]
3960 *) Fix installation procedure: Now that os-inline.c is actually used (a
3961 recently fixed bug prevented this) we need to also install os-include.c
3962 in addition to os.h into the PREFIX/include/ location or building of
3963 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3965 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3966 allow us to distinguish between a garbled DSO (or even a file which isn't
3967 an Apache module DSO at all) and a DSO which doesn't match the current
3968 Apache API. [Ralf S. Engelschall] PR#3152
3970 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3971 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3972 match case insensitive (this especially avoids nasty patterns like
3973 `[tT][eE][sS][tT]'). Second two additional internal map functions
3974 `escape' and `unescape' were added which can be used to escape/unescape
3975 to/from hex-encodings in URLs parts (this is especially useful in
3976 combination with map lookups).
3977 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3979 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3980 forgotten (because it was a macro) in the symbol renaming process.
3981 [Ralf S. Engelschall]
3983 *) Fix some inconsistencies related to the scopes of directives. The only
3984 user visible change is that the directives `UseCanonicalName' and
3985 `ContentDigest' now use the (more correct) `Options' scope instead of
3986 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3988 *) Using DSO, the Server token was being mangled. Specifically, the
3989 module's token was being added first before the Apache token. This
3990 has been fixed. [Jim Jagielski]
3992 *) Major overhaul of mod_negotiation.c, part 2.
3993 - properly handle "identity" within Accept-Encoding.
3994 - allow encoded variants in RVSA negotiation and let them appear in
3995 the Alternates field using the non-standard "encoding" tag-list.
3996 - fixed both negotiation algorithms so that an explicitly accepted
3997 encoding is preferred over no encoding if "identity" is not
3998 included within Accept-Encoding.
3999 - added ap_array_pstrcat() to alloc.c for efficient concatenation
4000 of large substring sequences.
4001 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
4004 *) Major overhaul of mod_negotiation.c, part 1.
4005 - cleanups to mod_negotiation comments and code structure
4006 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
4007 support for everything in the upcoming HTTP/1.1
4008 revision (draft-ietf-http-v11-spec-rev-06.txt).
4009 - language tag matching also handles tags with more than 2
4011 - empty Accept, Accept-Language, Accept-Charset headers are
4012 processed correctly; previously an empty header would make all
4013 values acceptable instead of unacceptable.
4014 - allowed for q values in Accept-Encoding
4015 - added support for transparent content negotiation (rfc2295 and
4016 rfc2296) (though we do not implement all features in these drafts,
4017 e.g. no feature negotiation). Removed old experimental version.
4018 - implemented 'structured entity tags' for better cache correctness
4019 (structured entity tags ensure that caches which can deal with Vary
4020 will (eventually) be updated if the set of variants on the server
4022 - this involved adding a vlist_validator element to request_rec
4023 - this involved adding the ap_make_etag() function to the global API
4024 - modified guessing of charsets used by Apache negotiation algorithm
4025 to guess 'no charset' if the variant is not a text/* type
4026 - added code to sort multiviews variants into a canonical order so that
4027 negotiation results are consistent across backup/restores and mirrors
4028 - removed possibility of a type map file resolving to another type map
4029 file as its best variant

4054 Now SHELL_PATH is started in these cases. [Martin Kraemer]
4056 *) PORT: Added the Cyberguard V2 port [Richard Stagg <stagg@lentil.org>]
4059 *) Update APXS manual page: some -q option arguments were missing
4060 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
4062 *) Cleanup the command line options: `-?' was documented to show
4063 the usage list but does it with an error because `?' is not a valid
4064 command. OTOH a lot of users expect `-h' to print such a usage list and
4065 instead are annoyed for ages by our huge unreadable list of directives.
4066 So we now changed the command line options this way:
4068 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
4069 very similar to the popular linker option.
4071 Intent: while -l gives the small list of modules, -L now gives the
4072 large list of directives implemented by these modules. This is also
4073 consistent with -v (short version info) and -V (large version info).
4075 Intent: it's now the expected option ;-)
4076 The manual page was adjusted accordingly.

4079 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
4080 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
4082 *) Removed recently introduced bugs and disfigurements in APACI:
4083 o fixed argument line processing: using $args was broken: It was not
4084 initialized and using args="$args $apc_option" and even args="$args
4085 \"$apc_option\"" fails in the second processing round for any arguments
4086 containing whitespaces. The only correct way is to use the construct
4087 "$@" (but not possible here) or iterate _both_ times over the implicit
4088 argument line (no argument to for-loop) which is what we now use.
4089 o make --with-layout=Apache the default without creating
4090 redundancy (copying the --with-layout block in the argument parsing
4091 loop). We achieve this by using the "$@" construct together with the
4092 `set' command to prepend --with-layout=Apache to the command line in
4093 case --with-layout is not used.
4094 o fixed auto-suffix handling now that config.layout exists.
4095 Paths which are auto-suffixed are marked with a trailing plus sign in
4096 config.layout and every path now can be marked this way (not only the
4097 four paths for which we do it currently). Additionally the suffix is
4098 no longer a static one. Instead it's now `/<target>' where <target> is
4099 the argument of the --target option or per default `httpd'.
4100 o allow also tabs (and only spaces) where we match whitespaces
4101 o various fixes and cleanups related to used shell coding style
4102 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
4103 o trimmed output of --help to fit into 80 columns

4128 *) Make generation of src/Configuration.apaci more robust: It failed to
4129 differenciate between modules when one module name was a postfix of
4130 another (e.g. cgi vs. fastcgi). We now check for mod_XXX, libXXX and even
4131 just XXX (think about totally non-standard names like "apache_ssl", too).
4132 [Ralf S. Engelschall] PR#3380
4134 *) In src/Configure remove the SERVER_SUBVERSION support (already deprecated

4139 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
4140 creates an external package shadow tree in DIR before the local build
4141 shadow tree is generated under DIR. This way one can have the extracted
4142 Apache distribution tree read-only on NFS or CDROM and still build Apache

4165 *) Fixed possible (but harmless in practice) bug in the DBM lookup
4166 procedure of mod_rewrite: very long keys were truncated.
4167 [Ralf S. Engelschall]
4169 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
4170 identifier, currently "Apache" and "GNU" are pre-defined in the file
4171 config.layout. Custom layouts are possible by using FILE:ID as the
4172 argument where the layout ID is taken from FILE.
4174 The config.layout file consists of <Layout ID>..</Layout> sections
4175 where inside those sections "path_variable: path_value" pairs can be
4176 specified. These lines are converted to path_variable='path_value'.
4178 *) Add a DefaultLanguage directive so that files missing a language
4179 extension (e.g., .fr, .de) can be labelled as being some other
4180 default language. DefaultLanguage can appear in <Directory> and
4181 <Files> containers as well as .htaccess files. [Paul Sutton]
4184 *) Fix TARGET configuration when configuring and installing using
4185 APACI configure. TARGET now defines the basename of the configuration
4186 file, startup script, manual page, etc. log_error_core() now reports

4526 *) Fix the recently introduced C header file checking: We now use the C
4527 pre-processor pass only (and no longer the complete compiler pass) to
4528 determine whether a C header file exists or not. Because only this way
4529 we're safe against inter-header dependencies (which caused horrible
4530 portability problems). The only drawback is that we now have a CPP
4531 configuration variable which has to be determined first (we do a similar
4532 approach as GNU Autoconf does here). When all fails the user still has
4533 the possibility to override it manually via APACI or src/Configuration.
4534 As a fallback for the header check itself we can directly check the
4535 existance of the file under /usr/include, too.

4584 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4586 *) mod_expires will now act on content that is not sent from a file
4587 on disk. Previously it would never add an Expires: header to
4588 any response that did not come from a file on disk; the only
4589 case where it still doesn't (and can't) add one for that type of
4590 content is if you are using a modification date based setting.

4606 a common problem of (mis-administrated?) IIS servers, make the apache
4607 proxy immune to these errors (and ignore the duplicates, but log
4608 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4610 *) The <IfModule and <IfDefine block starting directives now only
4611 allow exactly one argument. Previously, the optional negation
4612 character '!' could be separated by whitespace without a syntax
4613 error being reported, albeit defeating the IfModule functionality
4614 (enclosed directives would ALWAYS be executed). By using the
4615 stricter syntax, these hard-to-track errors can be avoided.
4618 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4619 cause the standalone FancyIndexing directive to logically OR
4620 into any existing IndexOptions settings rather than wiping
4621 them out. [Ken Coar]
4623 *) Changes in ftp proxy: make URL parsing simpler by using the
4625 + Add display of the "current directory" in cases where it's
4626 different from the supplied path (e.g., ftp://user@host/ lives
4627 in /home/user, not in /, therefore clicking on "../" in the
4628 starting directory might send us to /home/).
4629 + When ftp login fails, (esp. when a user name was part of the
4630 URL already), we now return [401 Unauthorized ] to allow the
4631 browser to pop up an authorization dialog. This makes passwords
4632 slightly less visible (they don't appear in the regular log files)
4633 and implements a functionality that other www proxy servers
4637 *) Triggered by the recent "Via:" header changes, the proxy module would
4638 dump core for replies with invalid headers (e.g., duplicate
4639 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4640 core dump is avoided. Also, broken replies are not cached.

4650 *) Replace the inlined information grabbing stuff for the configuration
4651 adjustment feature (no --without-confadjust) with calls to a new helper
4652 script `buildinfo.sh' which is both more flexible and already proofed to
4653 be more robust against platform differences. This mainly fixes the

4676 5 to 10 because there are some users out there who always have 5 to 8
4677 variables in one RewriteRule and had to patch mod_rewrite.h for every
4678 release. So 15 should be now more than enough, even for them. (I never
4679 needed more than 4 in my RewriteRules ;-)

4701 compile time, for least astonishment of the user.
4704 *) When READing a request in ExtendedStatus mode, the "old"
4705 vhost, request and client information is not displayed.
4708 *) STATUS is no longer available. Full status information now
4709 run-time configurable using the ExtendedStatus directive.
4712 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4713 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4714 a function which can be used to perform bulk update operations
4715 on tables in a more efficient manner. [Dean Gaudet]
4717 *) SECURITY: Added compile-time and configurable limits for
4718 various aspects of reading a client request to avoid some simple
4719 denial of service attacks, including limits on maximum request-line
4720 size (LimitRequestLine), number of header fields (LimitRequestFields),
4721 and size of any one header field (LimitRequestFieldsize). Also added
4722 a configurable directive LimitRequestBody for limiting the size of the
4723 request message body. [Roy Fielding]

4741 *) The 'status' module will now show the process pid's and their
4742 state even without full STATUS accounting. [Jim Jagielski]
4744 *) Restore the client IP address to the error log messages, this
4745 was lost during the transition from 1.2 to 1.3. Add a new
4746 function ap_log_rerror() which takes a request_rec * and
4747 formats it appropriately. [Dean Gaudet] PR#2661
4749 *) Cure ap_cfg_getline() of its nasty habit of compressing internal
4750 whitespace in input lines -- including within quoted strings.
4752 but leading and trailing whitespace should continue to be
4753 stripped [Martin Kraemer]
4755 *) Cleanup of the PrintPath/PrintPathOS2 helper functions. Avoid
4756 the ugly use of an env. variable and use command-line args for
4757 alternate $PATH. Make more like advanced 'type's as well.
4760 *) The IRIXN32 Rule was being ignored. Configure now correctly adds

4768 directory was renamed to src/os/os2/ for consistency.
4769 [Brian Havard, Ralf S. Engelschall]
4771 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4772 files (here modules) against other DSO files (here shared libraries).
4773 This is done by determining a subset of LIBS which can be safely used for
4774 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4775 disabled for all platforms to avoid problems with this (experimental)
4776 rule. But we provide it now for those people how ran into problems and
4777 want to came out by forcing linking against DSOs.

4921 [Ralf S. Engelschall] PR#2596
4923 *) mod_rewrite created RewriteLock files under the UID of the parent
4924 process, thus the child processes had no write access to the files.
4925 Now a chown() is done on the file to the uid of the children,
4926 if applicable. [Lars Eilebrecht, Ralf S. Engelschall] PR#2341
4928 *) Autogenerate some HAVE_XXXXX_H defines in conf_auto.h (determined via
4929 TestCompile) instead of defining them manually in conf.h based on less
4930 accurate platform definitions. This way we no longer have to fiddle with
4931 OS-type and/or OS-version identifiers to discover whether a system header
4932 file exists or not. Instead we now directly check for the existence of
4933 those esoteric ones.

4940 *) Set the RTLD_GLOBAL dlopen mode parameter to allow dynamically loaded
4941 modules to load their own modules dynamically. This improves mod_perl
4942 and mod_php3 when these modules are loaded dynamically into Apache.
4945 *) Cache a proxied request in the event that the client cancels the

4973 *) The APACI libexecdir was not extended with an "apache/" subdir
4974 if the installation prefix didn't already contain "apache", but
4975 it should be because the DSO files are Apache-specific. Now
4976 libexecdir is treated the same way sysconfdir, datadir, localstatedir

5029 *) WIN32: If we can't figure out how to execute a file in a script
5030 directory, bail out of the request with an error message. [W G Stoddard]
5032 *) WIN32 SECURITY: Eliminate directories consisting of three or more dots;
5033 these are treated by Win32 as if they are ".." but are not detected by
5034 other machinery within Apache. This is something of a kludge but
5035 eliminates a security hole. [Manoj Kasichainula, Ben Laurie]
5037 *) Move ap_escape_quotes() from src/ap to src/main/util.c; it uses
5038 pools and thus pollutes libap (until the pool stuff is moved there).
5041 *) IndexIgnore should be case-blind on Win32 (and any other case-aware
5042 but case-insensitive platforms). New #define for this added to conf.h

5052 (Group, Port, ServerAdmin, ServerName) via some intelligent tests to
5053 remove some of the classical hurdles for new users when setting up
5054 Apache. This is done per default because it is useful for the average
5055 user. Package authors can use the --without-confadjust option to disable
5056 these configuration adjustments.
5057 [Ralf S. Engelschall]
5059 *) Added an EXTRA_DEPS configuration parameter which can be used
5060 to add an extra Makefile dependency for the httpd target, for instance
5061 to external third-party libraries, etc.
5062 [Ralf S. Engelschall]
5064 *) Add <IfDefine>..</IfDefine> sections to the core module (with same spirit
5065 as <IfModule>..</IfModule> sections) which can be used to skip or process
5066 contained commands dependend of ``-D PARAMETER'' options on the command
5067 line. This can be used to achieve logical conditions like <IfDefine
5068 ReverseProxy> instead of physically ones (e.g. <IfModule mod_proxy.c>)
5069 and thus especially can be used for conditionally loading DSO-based
5070 modules via LoadModule, etc. [Ralf S. Engelschall]

5077 truncated which forced following HTTP headers to be data in the HTTP
5078 reponse. [Ralf S. Engelschall, Charles Fu <ccwf@bacchus.com>]
5081 *) Portability fix for APACI shadow tree support: Swap order of awk and sed
5082 in top-level configure script to avoid sed fails on some platforms (for
5083 instance SunOS 4.1.3 and NCR SysV) because of the non-newline-termined
5084 output of Awk. [Bill Houle <bhoule@sandiegoca.ncr.com>] PR#2435
5086 *) Improve performance of directory listings (mod_autoindex) by comparing
5087 integer keys (last-modified and size) as integers rather than converting
5088 them to strings first. Also use a set of explicit byte tests rather
5089 than strcmp() to check for parent directory-ness of an entry. Oh, and
5090 make sure the parent directory (if displayed) is *always* listed first
5091 regardless of the sort key. Overall performance winnage should be good
5092 in CPU time, instruction cache, and memory usage, particularly for large
5093 directories. [Ken Coar]
5095 *) Add a tiny but useful goody to APACI's configure script: The generation
5096 of a config.status script (as GNU Autoconf does) which remembers the used
5097 configure command and hence can be used to restore the configuration by
5098 just re-running this script or for remembering the configuration between
5100 [Ralf S. Engelschall]
5102 *) Add httpd -t (test) option for running configuration syntax tests only.
5103 If something is broken it complains and exits with a return code
5104 non-equal to 0. This can be used manually by the user to check the Apache
5105 configuration after editing and is also automatically used by apachectl
5106 on (graceful) restart command to make sure Apache doesn't die on restarts
5107 because of a configuration which is now broken since the last (re)start.
5108 This way `apachectl restart' can be used inside cronjobs without having
5109 to expect Apache to be falling down. Additionally the httpd -t can be run
5110 via `apachectl configtest'.

5249 ap_spawn_child_err_buff became ap_bspawn_child
5250 spawn_child was obsoleted and moved to compat.h
5253 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5254 programs: ap_spawn_child_err() is used and the Win32 case now uses
5255 CreateProcess() instead of a low-level execl() (which caused problems in
5256 the past under Win32).
5257 [Ralf S. Engelschall]
5259 *) A few cosmetics and trivial enhancements to APXS to make the
5260 generated Makefile more user friendly. [Ralf S. Engelschall]
5262 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5263 was updated to use the normal apache error processing, thereby allowing
5264 proxy errors to be treated by ErrorDocument's as well. For this
5265 purpose, a new module-to-core communication variable "error-notes"
5266 was introduced; the proxy (and possibly other modules) communicates
5267 its error text using this variable. Its content is copied to a new
5268 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5269 The old proxy special error routine ap_proxy_log_uerror()
5270 was replaced by regular ap_log_error() calls, many messages were made

5274 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5277 *) Transform the configure message "You need root privileges for suEXEC"
5278 from a fatal error into a (more friendly) warning because the building
5279 ("make") of Apache we can allow, of course. Root privileges are needed
5280 only for the installation step ("make install"). So make sure the
5281 user is aware of this fact but let him proceed as long as he can.

5343 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5345 *) The proxy cache would store an incorrect content-length in the cached

5347 of the original copy instead of using the cached copy.
5348 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5350 *) The Makefiles assumed that DSO files are build via $(LD). This
5351 is broken for two reasons: First we never defined at least LD=ld
5352 somewhere to make sure this works (it was silently assumed that most Make
5353 provide a built-in LD definition - ARGL!) and second using the generic LD
5354 variable is not the truth. Instead a special variable named LD_SHLIB is
5355 reasonable because although "ld" is usually the default, the command for
5356 building DSO files can be "libtool" or even "cc" on some systems.
5357 [Ralf S. Engelschall]
5359 *) Replace the AddVersionPlatform directive with ServerTokens which
5360 provides for more control over the format of the Server:
5361 header line. SERVER_SUBVERSION is no longer supported;
5362 all module should use the ap_add_version_component()

5369 not retrieved in src/Configure and thus was not useable.
5370 [Ralf S. Engelschall]
5372 *) Various Makefile consistency cleanups:
5373 - make OSDIR also automatically be relative to src/ like INCDIR
5374 - SUBDIRS is now generated in src/Makefile only and not in
5375 Makefile.config because it is a local define for this location.
5376 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5377 any Makefile but make sure that at least the "-K inline" is kept in
5379 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5380 - updated the dependencies theirself
5381 - removed not existing SHLIB variable from "clean" targets
5382 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5383 already exists and OBJS_PIC are also just plain objects and have not
5384 directly to do with "shared" things. The only difference is that they
5385 contain PIC. So OBJS_PIC is the more canonical name.
5386 - Updated the Makefile-dependency lines for OBJS_PIC
5387 - Removed the Makefile-dependency line in Configure to avoid double
5389 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5390 of xxx.lo as GNU libtool does with its PIC objects
5391 - reduce local complexity in modules Makefile.tmpl by moving the last
5392 existing target "depend" to the generation section in Configure, too.
5393 - removed the historical $(SPACER) which was used in the past together
5394 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5395 is no longer needed.
5396 - force the build and run of the gen_xxx programs under main/ as the
5397 first step before building the objects because it looks cleaner
5398 [Ralf S. Engelschall]

5409 *) When opening "configuration" files (like httpd.conf, htaccess
5410 and htpasswd), Apache will not allow them to be non-/dev/null
5411 device files. This closes a DoS hole. At the same time,
5412 we use ap_pfopen to open these files to handle timeouts.
5413 [Jim Jagielski, Martin Kraemer]
5415 *) Apache will now log the reason its httpd children exit if they exit
5416 due to an unexpected signal. (It requires a new porting define,
5417 SYS_SIGLIST, which if defined should point to a list of text
5418 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5420 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5421 like WIN32. Before, Win32 CGI's could have had sporadic failures
5422 if a chdir call from one thread was made between another chdir call
5423 and a spawn in another thread. So, for now don't chdir for CGI scripts
5424 in WIN32. The current CGI "spec" is unclear as to whether it's
5425 necessary. Long-term fix is to either serialize the chdir/spawn combo
5426 or use WIN32 native calls to spawn a process. This temp fix was
5427 necessary to remove this as a showstopper for 1.3's release.
5430 *) Cleanup the suEXEC support in APACI and make it more safe:
5431 1. Add big fat hint in INSTALL about risks and to read the
5432 htdocs/manual/suexec.html document before using the suexec-related
5434 2. Make sure the user has at least provided one --suexec-xxxx option
5435 (specifies suEXEC parameters) in addition to --enable-suexec option.
5436 If only --enable-suexec is given APACI stops with a hint to INSTALL
5437 and htdocs/manual/suexec.html documents.
5438 3. Provide two additional --suexec-xxxx options to make the suEXEC
5439 configuration complete (especially for package maintainers who else
5440 had to patch the source tree) by providing ways to configure minimal
5441 UID/GID and safe PATH, too.
5442 [Ralf S. Engelschall]
5444 *) Cleanup of the `configure --shadow' process:
5445 - make sure the configure script creates its temporary files in the
5446 shadow tree to avoid conflicts with parallel configure runs
5447 - removed unnecessary option "-r" from "rm" call for Makefiles
5448 - make sure the configure scripts creates the shadow-wrapper Makefile
5449 only when no shadow trees already exists
5450 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5451 when no more shadow trees exists
5452 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5453 as fast (in the past it needed 70sec, now it runs just 38sec)
5454 - make sure CVS does not complain about the created files
5455 Makefille.<gnutriple> and directories src.<gnutriple>
5456 [Ralf S. Engelschall]
5458 *) Added the ap_add_version_component() API routine and the
5459 AddVersionPlatform core directive. The first allows modules to
5460 declare themselves in the Server response header field value,
5461 augmenting the SERVER_SUBVERSION define in the Configuration file
5462 with run-time settings (more useful in a loadable-module environment).
5463 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5464 into the server version string. [Ken Coar] PR#2056
5466 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5469 *) Emit the "Accept-Range" header for the default handler.
5470 [Brian Behlendorf] PR#1464
5472 *) Add a note to httpd.conf-dist that apache will on some systems fail
5473 to start when the Group # is set to a negative or large positive value.
5476 *) Make sure the module execution order is correct even when some modules
5477 are loaded under runtime (`LoadModule') via the DSO mechanism:
5478 1. The list of loaded modules is now a dynamically allocated one
5479 and not the original statically list from modules.c
5480 2. The loaded modules are now correctly setup by LoadModule for
5481 later use by the AddModule command.
5482 3. When the DSO mechanism for modules is used APACI's `install'
5483 target now enables all created `LoadModule' lines per default because
5484 this is both already expected by the user _and_ needed to avoid
5485 confusion with the next point and reduces the Makefile.tmpl complexity
5486 4. When the DSO mechanism for modules is used, APACI's `install'
5487 target now additionally makes sure the module list is reconstructed
5488 via a complete `ClearModuleList+AddModule...' entry.
5489 5. The support tool `apxs' now also makes sure an AddModule command
5490 is added in addition to the LoadModule command.
5491 6. The modules.c generation was extended to now contain two
5492 comments to make sure no one is confused by the confusing terminology
5493 of loading/linking (we use load=link+load & link=activate instead of
5494 the obvious load=activate & link=link :-( )
5495 This way now there is no longer a difference under execution time between
5496 statically and dynamically linked modules.
5497 [Ralf S. Engelschall]
5499 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5500 Big Symbol Renaming. [Ralf S. Engelschall]
5502 *) Add a comment to mod_example.c showing the format of a FLAG command
5505 *) Standardized the time format in mod_status to match that of other
5506 places in the code (e.g. DATE_GMT). PR#1551
5508 *) Fix handling of %Z in timefmt strings for those platforms with no time
5509 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5512 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5513 feature compatible with 'UseCanonicalName off' by changing
5514 r->server->server_hostname to ap_get_server_name(). And I changed some
5515 functions which use r->server->port to use ap_get_server_port() instead,
5516 because if there's no Port directive in the config r->server->port is 0.
5519 *) get/set_module_config are trivial enough to be better off inline. Worth
5520 1.5% performance boost. [Dean Gaudet]
5522 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5523 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5526 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5527 the task environment to the unprivileged User id. Otherwise CGI scripts
5528 would have a way to gain super user access. [Martin Kraemer]
5530 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5531 absolute path, only log base name of logging source as is done
5532 in unix. [Martin Kraemer]
5534 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5535 the encoding type from the Accept-Encoding header (if it's there)
5536 and use it in the response, as that's probably what it'll be expecting.
5537 [Ronald.Tschalaer@psi.ch]
5539 *) Fix to mod_alias: translate_alias_redir is dealing with
5540 a URI, not a filename, so the check for drive letters for win32
5541 and emx is not necessary. [Dean Gaudet]
5543 *) WIN32: Allow .cmd as an executable extension.

5546 *) Make Apache header files, and some variables, C++ friendly.
5547 [Michael Anderson's <mka@redes.int.com.mx>]
5549 *) Child processes can now "signal" (by exiting with a status
5550 of APEXIT_CHILDFATAL) the parent process to abort and
5551 shutdown the server if the error in the child process was
5552 fatal enough. [Jim Jagielski]
5554 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5555 [Jim Jagielski] PR#2112
5557 *) Make sure the referer_log and agent_log entries in the default httpd.conf
5558 file are also adjusted for the actual relative installation paths.
5559 [Ralf S. Engelschall] PR#2175
5561 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5563 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5566 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5567 Additionally the checks for finding the vendor DSO library were moved
5568 from mod_so.c to Configure because first it needs $PLAT etc. and second
5569 mod_so already uses an abstraction layer and does not fiddle with the
5570 vendor functions itself.
5571 [Jens-Uwe Mager, Ralf S. Engelschall]
5573 *) PORT: Some optimization defines for NetBSD
5574 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5576 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5577 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5579 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5580 AIX variants should work fine, too. Even AIX 3.x should work). This is
5581 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5582 which we put into a os/unix/os-dso-aix.c file.
5583 [Ralf S. Engelschall]
5585 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5586 that we should use NET_SIZE_T == int but the include files force size_t.
5587 [Ralf S. Engelschall]
5589 *) Fix two bugs in select() handling in http_main.c.
5592 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5593 is unset (as it is in situations like timeouts) where it is unclear
5594 whether errno is set or not. [Martin Kraemer]
5596 *) Just having APACI's localstatedir is too general and not enough for most
5597 of the systems. 1.3b6 again required manual APACI patches by package
5598 maintainers from RedHat and FreeBSD because for their filesystem layout a
5599 little bit more flexibility in configuring the paths is needed. Hence we
5600 provide three additional configure options (--runtimedir, --logfiledir,
5601 --proxycachedir) which now can be used for more granular adjustments if
5602 --localstatedir is not enough to fit the particular needs. As a nice
5603 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5604 [Ralf S. Engelschall]
5606 *) Make the install root for "make install" in APACI's Makefile overrideable
5607 by package authors. This way we are even more friendly to package
5608 maintainers (especially Debian and RedHat) who build for the real prefix
5609 via "configure --prefix=/<real>" but use a different local prefix via
5610 "make root=/tmp/apache install" for rolling the package without bristling
5611 the target location on their system.
5612 [Ralf S. Engelschall]
5614 *) Workaround sed limitations in APACI's configure script by now
5615 substituting in chunks of 50 commands (because for instance HPUX's vendor
5616 sed has a limit of max. 98 commands)
5617 [Ralf S. Engelschall] PR#2136
5619 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5620 [Ralf S. Engelschall] PR#2140
5622 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5623 RENAMING process because they are defined as pre-processor macros instead
5624 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5625 [Ralf S. Engelschall]
5627 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5628 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5629 [Ralf S. Engelschall] PR#2139
5631 *) Various bugfixes and cleanups for the APACI configure script:
5632 o fix IFS handling for _nested_ situation
5633 o fix Perl interpreter search: take first one found instead of last one
5634 o fix DSO consistency check
5635 o print error messages to stderr instead of stdout
5636 o add install-quiet for --shadow situation to Makefile stub
5637 o reduce complexity by avoiding sed-hacks for rule and module list loops
5638 [Ralf S. Engelschall]
5640 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5642 *) Make sure the input field separator (IFS) shell variable is explicitly
5643 initialized correctly before _every_ `for' loop and also restored after
5644 the loops. [Ralf S. Engelschall]
5646 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5647 `magic' files from an existing Apache installation. Because people often
5648 customize these for own MIME and content types.

5655 [Ralf S. Engelschall] PR#2105
5657 *) Let "configure" clear out the users parameters (provided as shell

5660 [Ralf S. Engelschall] PR#2101
5662 *) Provide backward compatibility from some old src/Configuration.tmpl
5663 parameter names to the canonical Autoconf-style shell variable names. For

5686 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5688 *) If you start apache with the -S command line option it will dump
5689 out the parsed vhost settings. This is useful for folks trying
5690 to figure out what is wrong with their vhost configuration.
5691 (Other dumps may be added in the future.) [Dean Gaudet]
5693 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5694 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5697 *) Because /usr/local/apache is the default prefix the ``configure
5698 --compat'' option no longer has to set prefix, again. This way the
5699 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5701 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5702 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5703 to avoid "discard const" warnings. [Ralf S. Engelschall]
5705 *) If a specific handler is set for a file yet the request still
5706 ends up being handled by the default handler, log an error
5707 message before handling it. This catches things such as trying
5708 to use SSIs without mod_include enabled. [Marc Slemko]
5710 *) Fix error logging for the startup case where ap_log_error() still uses
5711 stderr as the target. Now the default log level is honored here, too.
5712 [Ralf S. Engelschall]
5714 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5715 long" errors when generating the MODULES entry for src/Makefile

5719 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5721 Changes with Apache 1.3b6
5723 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5725 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5726 interface via the similar but proprietary HP/UX shl_xxx-style system
5727 calls. [Ralf S. Engelschall]
5729 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5730 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5731 Make. [Ralf S. Engelschall]
5733 *) ++++ THE BIG SYMBOL RENAMING ++++
5734 To avoid symbol clashes with third-party code compiled into the server,
5735 we globally applied the prefix "ap_" to the following classes of
5737 - Apache provided general functions (e.g., ap_cpystrn)
5738 - Public API functions (e.g., palloc, bgets)
5739 - Private functions which we can't make static (because of
5740 cross-object usage) but should be (e.g., new_connection)
5741 For backward source compatibility a new header file named compat.h was
5742 created which provides defines for the old symbol names and can be used
5743 by third-party module authors.
5746 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5747 problem under SVR4 is that there is no command flag to force the linker
5748 to export the global symbols of the httpd executable therewith they are
5749 available to the DSO's. Instead of problematic hacks like creating a
5750 dummy.so file (containing dummy references to all global symbols) the
5751 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5752 Placing the Apache core code itself into a DSO library named libhttpd.so.
5753 This way the global symbols _HAVE_ to be exported and thus are available
5754 to any manually loaded DSO's under runtime. To reduce the impact to the
5755 user to null we go even further and create a stub httpd executable which
5756 automatically keeps track of the DSO library loading itself and thus
5757 hides the complete mechanism from the user. Although the generation of
5758 this DSO library is automatically triggered for platforms which
5759 essentially need it (mostly all SVR4-derivates) it can be also enabled
5760 manually via the Rule SHARED_CORE. This can be interesting in the future
5761 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5762 features like graceful upgrades, or whatever.
5763 [Ralf S. Engelschall, Martin Kraemer]
5765 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5767 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5768 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5769 conventions while "clean" removes only stuff created by "all" targets,
5770 "distclean" additionally removes the stuff from the configuration
5771 process. This way "make distclean" (hence the name) provides a fresh
5772 source tree as it was for distribution.
5773 [Ralf S. Engelschall]
5775 *) Allow top-level (APACI) Makefile to break on build errors
5776 the same way the src/ subtree Makefiles breaks on them by replacing the
5777 initial APACI sed-subdir-display-kludge with a more clean
5778 variable-passing-solution: variable SDP can optionally hold the subdir
5779 prefix which is consistently used for displaying the subdir movement.
5780 This way even the top-level Makefile can stop correctly on errors as the
5781 user expects. [Ralf S. Engelschall]
5783 *) Fixed ordering of argument checks for RewriteBase directive.
5784 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5786 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5787 indicating that a module is being compiled for dynamic loading. Also
5788 remove #define IS_MODULE from modules and add SHARED_MODULE define
5789 to the mak/dsp files. [Alexei Kosut]
5791 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5792 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5794 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5796 *) Add documentation file and src/Configuration.tmpl entry for the
5797 experimental mod_mmap_static module. Because although it is and marked as
5798 an experimental one it is distributed and thus should be documented and
5799 prepared for configuration the same way as all others modules.
5800 [Ralf S. Engelschall]
5802 *) Add query (-q) option to apxs support tool to be able to manually query
5803 specific settings from apxs. This is needed for instance when you
5804 manually want to access Apache's header files and you need to assemble
5805 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5806 [Ralf S. Engelschall]
5808 *) Now src/Configure uses a fallback strategy for the shared object support
5809 on platforms where no explicit information is available: If a Perl
5810 installation exists we ask it about its shared object support and if it's
5811 the dlopen-style one we shamelessly guess the compiler and linker flags
5812 for creating shared objects from Perls knowledge. Of course, the user is
5813 warning about what we are doing and informed that he should send us
5814 the guessed flags when they work. [Ralf S. Engelschall]
5816 *) Provide APACI --without-support option to be able to disable the build
5817 and installation of the support tools from the src/support/ area.
5818 Although its useful to have these installed per default we should provide
5819 a way to compile and install without them for backward-compatibility.
5820 [Ralf S. Engelschall]
5822 *) Add of the new APache eXtenSion (apxs) support tool for building and
5823 installing modules into an _already installed_ Apache package through the
5824 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5825 this approach actually doesn't need the Apache source tree. The
5826 (APACI-installed) server package is enough, because this now includes the
5827 Apache C header files (PREFIX/include) and the new APXS tool
5828 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5829 module authors to build their Apache modules _OUTSIDE_ the Apache source
5830 tree while avoiding them to fiddle around with the totally platform
5831 dependend way of compiling DSO files. The tool supports all ranges of
5832 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5833 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5834 on-the-fly generate a minimalistic Makefile and sample module for the
5835 first step to provide both a quick success event and to demonstrate the
5836 APXS mechanism to module authors. [Ralf S. Engelschall]
5838 *) Fix core dumps in use of CONNECT in proxy.
5839 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5841 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5842 so that users have examples of how CustomLog can be used.
5845 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5846 the Apache distribution tree. Until Apache 1.3 there was no real
5847 out-of-the-box batch-capable build and installation procedure for the
5848 complete Apache package. This is now provided by a top-level "configure"
5849 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5850 to provide a GNU Autoconf-style frontend which is capable to both drive
5851 the old src/Configure stuff in batch and additionally installs the
5852 package with a GNU-conforming directory layout. Any options from the old
5853 configuration scheme are available plus a lot of new options for flexibly
5854 customizing Apache. [Ralf S. Engelschall]
5856 *) The floating point ap_snprintf code wasn't threadsafe.

5866 Configure knows which CC we are using. [Jim Jagielski]
5868 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5869 was defined in a parent directory. [Lars Eilebrecht]
5871 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5872 a generic printf-style routine that can call arbitrary output
5873 routines. Use this to replace http_bprintf.c. Add new routines
5874 psprintf(), pvsprintf() which allocate the exact amount of memory
5875 required for a string from a pool. Use psprintf() to clean up
5876 various bits of code which used ap_snprintf()/pstrdup().
5879 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5880 ap_snprintf() has different semantics and formatting codes than
5881 snprintf(). [Dean Gaudet]
5883 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5884 is necessary on at least Solaris where the /etc/rc?.d scripts
5885 are run with these signals ignored, and "SIG_IGN" settings are
5886 maintained across exec().

5914 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5915 therefore not exposed to %2F -> '/' translations and 2) the request
5916 is a proxy request, so we're not dealing with a local resource anyway.
5917 Without this, the proxy would fail to work for any URL's with
5918 %2f in them (occurs quite often in
5919 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]

5934 header if available. [Ralf S. Engelschall] PR#1183
5936 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5937 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5938 name was really too generic, added documentation for this directive to
5939 the mod_proxy.html and corrected the hyperlink to it in the

5948 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5949 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5950 and per default compiled support programs have manual pages - just to
5951 document our stuff a little bit more and to be able to do really
5952 Unix-like installations ;-) [Ralf S. Engelschall]
5954 *) Major cleanups to the Configure script to make it and its generated
5955 Makefiles again readable and maintainable: add SRCDIR option, removed
5956 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5957 generated sections, consequently added Makefile headers with inheritance
5958 information, added subdir movement messages for easier following where
5959 the build process currently stays (more verbose then standard Make, less
5960 verbose than GNU make), same style to comments in the Configure script,
5961 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5963 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5964 from the ZeusBench benchmarking program and can be used to determine the
5965 response performance of an Apache installation. This version is
5966 officially licensed with Zeus Technology, Ltd. See the license agreement

5972 more have been marked CORE_EXPORT and are not intended for general
5973 use by modules. [Doug MacEachern, Dean Gaudet]
5975 *) mod_proxy was not clearing the Proxy-Connection header from

5986 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5988 *) Clean up some undocumented behavior of mod_setenvif related to
5989 "merging" two SetEnvIf directives when they match the same header
5990 and regex. Document that mod_setenvif will perform comparisons in
5991 the order they appear in the config file. Optimize mod_setenvif by
5992 doing more work at config time rather than at runtime.
5995 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5996 to allow for modules to overrule them and to reduce redefinition
5997 warnings [Jim Jagielski]
5999 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
6002 *) Making the hard-coded cross-module function call mime_find_ct() (from
6003 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
6004 checking is really called even for proxy requests except for URLs with
6005 HTTP schemes (because there we can optimize by not running the type
6006 checking hooks due to the fact that the proxy gets the MIME Content-type
6007 from the remote host later). This change cleans up mod_mime by removing
6008 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
6009 especially unbundles mod_proxy and mod_mime. This way they both now can
6010 be compiled as shared objects and are no longer tied together.
6011 [Ralf S. Engelschall]
6013 *) util.c cleanup and speedup. [Dean Gaudet]
6015 *) API: Clarification, pstrndup() will always copy n bytes of the source
6016 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
6018 *) Mark module command_rec and handler_rec structures const so that they
6019 end up in the read-only data section (and are friendlier to systems
6020 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
6022 *) Add check to the "Port" directive to make sure the specified
6023 port is in the appropriate range. [Ben Hyde]
6025 *) Performance improvements to invoke_handler().
6026 [Dmitry Khrustalev <dima@bog.msu.su>]
6028 *) Added support for building shared objects even for library-style modules
6029 (which are built from more than one object file). This now provides the
6030 ability to build mod_proxy as a shared object module. Additionally
6031 modules like mod_example are now also supported for shared object
6032 building because the generated Makefiles now no longer assume there is at
6033 least one statically linked module. [Ralf S. Engelschall]
6035 *) API: Clarify usage of content_type, handler, content_encoding,
6036 content_language and content_languages fields in request_rec. They
6037 must always be lowercased; and the strings pointed to shouldn't
6038 be modified (you must copy them to modify them). Fix a few bugs
6039 related to this. [Dean Gaudet]
6041 *) API: Clarification: except for RAW_ARGS, all command handlers can
6042 treat the char * parameters as permanent, and modifiable. There
6043 is no need to pstrdup() them. Clean up some needless pstrdup().
6046 *) Now mod_so keeps track of which module shared objects with which names
6047 are loaded and thus avoids multiple loading and unloading and irritating
6048 error_log messages. [Ralf S. Engelschall]
6050 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
6051 environment variable in the apache core. But that tweaking interferes
6052 with mod_setenv. So don't tweak if the user has specified an explicit
6053 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888

6063 *) Various improvements to the configuration and build support for compiling
6064 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
6065 OSF1 support with GCC and vendor compilers was added. This way shared
6066 object support is now provided out-of-the-box for FreeBSD, Linux,
6067 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
6068 [Ralf S. Engelschall]
6070 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
6071 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
6072 and USE_OS2_SCOREBOARD. [Dean Gaudet]
6074 *) Fix one more special locking problem for RewriteMap programs in
6075 mod_rewrite: According to the documentation of flock(), "Locks are on
6076 files, not file descriptors. That is, file descriptors duplicated
6077 through dup(2) or fork(2) do not result in multiple instances of a lock,
6078 but rather multiple references to a single lock. If a process holding a
6079 lock on a file forks and the child explicitly unlocks the file, the
6080 parent will lose its lock.". To overcome this we have to make sure the
6081 RewriteLock file is opened _AFTER_ the childs were spawned which is now
6082 the case by opening it in the child_init instead of the module_init API
6083 hook. [Ralf S. Engelschall] PR#1029
6085 *) Change to Location and LocationMatch semantics. LocationMatch no
6086 longer lets a single slash match multiple adjacent slashes in the
6087 URL. This change is for consistency with RewriteRule and
6088 AliasMatch. Multiple slashes have meaning in URLs that they do
6089 not have in (some) filesystems. Location on the other hand can
6090 be considered a shorthand for a more complicated regex, and it
6091 does match multiple slashes with a single slash -- which is
6092 also consistent with the Alias directive.

6095 *) Fix bug with mod_mime_magic causing certain files, including files
6096 of length 0, to result in no response from the server.
6099 *) The Configure script now generates src/include/ap_config.h which
6100 contains the set of defines used when Apache is compiled on a platform.
6101 This file can then be included by external modules before including
6102 any Apache header files in case they are being built separately from
6103 Apache. Along with this change, a couple of minor changes were
6104 made to make Apache's #defines coexist peacefully with any autoconf
6105 defines an external module might have. [Rasmus Lerdorf]
6107 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
6108 but without any RewriteXXXXX directives. Here mod_rewrite is given no
6109 chance by the API to initialize its per-server configuration and thus
6110 receives the wrong one from the main server. This is now avoided by
6111 remembering the server together with the config structure while
6112 configuring and later assuming there is no config when we see a
6113 difference between the remembered server and the one calling us.
6114 [Ralf S. Engelschall] PR#1790
6116 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
6117 is automatically disabled under configure time when the dbm_xxx functions
6118 are not available. Second, two heavy source code errors in the DBM
6119 support code were fixed. This makes DBM RewriteMap's usable again after
6120 a long time of brokenness. [Ralf S. Engelschall] PR#1696
6122 *) Now all configuration files support Unix-style line-continuation via
6123 the trailing backslash ("\") character. This enables us to write down
6124 complex or just very long directives in a more readable way. The
6125 backslash character has to be really the last character before the
6126 newline and it has not been prefixed by another (escaping) backslash.

6138 *) WIN32: Preserve trailing slash in canonical path (and hence
6139 in PATH_INFO). [Paul Sutton, Ben Laurie]
6141 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
6142 depending on the rev of Solaris and what mixture of modules
6143 are in use. So it has been disabled, and Solaris is back to
6144 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
6145 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
6146 up static content only servers. Or it may fail unpredictably.

6149 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
6152 *) API: Rewrite of absoluteURI handling, and in particular how
6153 absoluteURIs match vhosts. Unless a request is a proxy request, a
6154 "http://host" url is treated as if a similar "Host:" header had been
6155 supplied. This change was made to support future HTTP/1.x protocols
6156 which may require clients to send absoluteURIs for all requests.
6158 In order to achieve this change subtle changes were made to the API. In a
6159 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
6160 that the unmodified uri can be retrieved easily. r->proxyreq is not set
6161 by the core, modules must set it during the post_read_request or
6162 translate_names phase.
6164 Plus changes to the virtualhost test suite for absoluteURI testing.
6166 This fixes several bugs with the proxy proxying requests to vhosts
6167 managed by the same httpd.
6170 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
6171 code from mod_rewrite. The vhost matching is now performed by a
6172 globally available function matches_request_vhost(). [Dean Gaudet]

6188 *) API: A new source module main/util_uri.c; It contains a routine
6189 parse_uri_components() and friends which breaks a URI into its component
6190 parts. These parts are stored in a uri_components structure called
6191 parsed_uri within each request_rec, and are available to all modules.
6192 Additionally, an unparse routine is supplied which re-assembles the URI
6193 components back to an URI, optionally hiding the username:password@ part
6194 from ftp proxy requests, and other useful routines. Within the structure,
6195 you find on a ready-for-use basis:
6196 scheme; /* scheme ("http"/"ftp"/...) */
6197 hostinfo; /* combined [user[:password]@]host[:port] */
6198 user; /* user name, as in http://user:passwd@host:port/ */
6199 password; /* password, as in http://user:passwd@host:port/ */
6200 hostname; /* hostname from URI (or from Host: header) */
6201 port_str; /* port string (integer representation is in "port") */
6202 path; /* the request path (or "/" if only scheme://host was given) */
6203 query; /* Everything after a '?' in the path, if present */
6204 fragment; /* Trailing "#fragment" string, if present */
6205 This is meant to serve as the platform for *BIG* savings in
6206 code complexity for the proxy module (and maybe the vhost logic).
6209 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
6210 ${map:key}) available for all location where a string is created in
6211 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
6212 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
6213 possible expansions are consequently usable at all string creation
6214 locations. [Ralf S. Engelschall]
6216 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6217 and not 1) and the per-virtual-server merging of directives. Now all
6218 directives except `RewriteEngine' and `RewriteOption' are either
6219 completely overridden (default) or completely inherited (when
6220 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6229 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6230 (like SunOS and FreeBSD) which don't accept the locking of pipes
6231 directly. A new directive RewriteLock is introduced which can be used to
6232 setup a separate locking file which then is used for synchronization.

6248 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6250 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6251 type but with a special post-processing for the looked-up value: It
6252 parses it into alternatives according to `|' chars and then only one
6253 particular alternative is chosen randomly (this is an essential
6254 functionality needed for balancing between backend-servers when using
6255 Apache as a Reverse Proxy. The looked up value here is a list of
6256 servers). Second, `int' with the built-in maps named `tolower' and
6257 `toupper' which can be used to map URL parts to a fixed case (this is an
6258 essential feature to fix the case of server names when doing mass
6259 virtual-hosting with the help of mod_rewrite instead of using
6260 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6261 Jay Soffian <jay@cimedia.com>] PR#1631
6263 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6264 This directive lets Apache adjust the URL in Location-headers on HTTP
6265 redirect responses sent by the remote server. This way the virtually
6266 mapped area is no longer left on redirects and thus by-passed which is
6267 especially essential when running Apache as a reverse proxy.

6388 *) Fix a memory leak on keep-alive connections. [Igor Tatarinov]
6390 *) Added mod_so module to support dynamic loading of modules on Unix

6415 *) Yet another rearrangement of the source tree.. now all the common
6416 header files are in the src/include directory. The -Imain -Iap
6417 references in Makefiles have been changed to the simpler -Iinclude
6418 instead. In addition to simplifying the build a little bit, this
6419 also makes it clear when a module is referencing something in a
6420 other than kosher manner (e.g., the proxy including mod_mime.h).
6421 Module-private header files (the proxy, mod_mime, the regex library,
6422 and mod_rewrite) have not been moved to src/include; nor have
6423 the OS-abstraction files. [Ken Coar]
6425 *) Fix a bug where r->hostname didn't have the :port stripped
6426 from it. [Dean Gaudet]
6428 *) Tweaked the headers_out table size, and the subprocess_env
6429 table size guess in rename_original_environment(). Added
6430 MAKE_TABLE_PROFILE which can help discover make_table()
6431 calls that use too small an initial guess, see alloc.c.
6434 *) Options and AllowOverride weren't properly merging in the main
6435 server setting inside vhosts (only an issue when you have no
6436 <Directory> or other section containing an Options that affects
6437 a request). Options +foo or -foo in the main_server wouldn't
6438 affect the main_server's lookup defaults. [Dean Gaudet]

6452 *) mod_unique_id was erroneously generating a second unique id when
6453 an internal redirect occured. Such redirects occur, for example,
6454 when processing a DirectoryIndex match. [Dean Gaudet]
6456 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6457 of the key and value. But in many cases this is not required
6458 because the key/value is a constant, or the value has been built
6459 by pstrcat() or other similar means. New routines table_addn,
6460 table_mergen, and table_setn have been added to the API, these
6461 routines do not pstrdup() their arguments. The core code and
6462 standard modules were changed to take advantage of these routines.
6463 The resulting server is up to 20% faster in some situations.
6465 Note that it is easy to get code subtly wrong if you pass a key/value
6466 which is in a pool other than the pool of the table. The only
6467 safe thing to do is to pass key/values which are in the pool of
6468 the table, or in one of the ancestors of the pool of the table.
6469 i.e. if the table is part of a subrequest, a value from the main
6470 request's pool is OK since the subrequest pool is a sub_pool of the
6471 main request's pool (and therefore has a lifespan at most as long as
6472 the main pool). There is debugging code which can detect improper
6473 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.

6482 *) PORT: Some older *nix dialects cannot automatically start scripts
6483 which begin with a #! interpreter line (the shell starts the scripts

6489 *) API: "typedef array_header table" removed from alloc.h, folks should
6490 have been writing to use table as if it were an opaque type, but even
6491 some standard modules got this wrong. By changing the definition
6492 to "typedef struct table table" module authors will receive compile
6493 time warnings that they're doing the wrong thing. This change
6494 facilitates future changes with more sophisticated table
6495 structures. Specifically, module authors should be using table_elts()
6496 to get access to an array_header * for the table. [Dean Gaudet]

6499 library routines. [Ken Coar, Rasmus Lerdorf]
6501 *) WIN32: mod_speling is now available on the Win32 platform.
6504 *) For clarity the following compile time definition was changed:
6506 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6508 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6509 and not be a general notice that the OS has mmap(). Now the
6510 HAVE_MMAP/SHMGET #defines strictly are informational that the
6511 OS has that method of shared memory; the type to use for
6512 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6513 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6514 determine if shared memory is available and allows Apache
6515 to determine the best method to use for the scoreboard.

6915 errno is now forced to EINVAL first in this case. [Ken Coar]
6917 *) A sed command in the Configure script pushed the edge of POSIXness,
6918 breaking on some systems. [Bhaba R.Misra <system@vt.edu>] PR#1368
6920 *) Solaris >= 2.5 was totally broken due to a mess up using pthread
6921 mutexes. [Roy Fielding, Dean Gaudet]

7001 *) Various improvements in detecting config file errors (missing closing
7002 directives for <Directory>, <Files> etc. blocks, prohibiting global
7003 server settings in <VirtualHost> blocks, flagging unhandled multiple
7004 arguments to <Directory>, <Files> etc.)
7007 *) Add support to suexec wrapper program for mod_unique_id's UNIQUE_ID
7008 variable to provide this one to suexec'd CGIs, too.
7009 [M.D.Parker <mdpc@netcom.com>] PR#1284
7011 *) New support tool: src/support/split-logfile, a sample Perl script which
7012 splits up a combined access log into separate files based on the
7013 name of the virtual host (listed first in the log records by "%v").
7016 Changes with Apache 1.3b2 (there is no 1.3b1)
7018 *) TestCompile was not passing $LIBS [Dean Gaudet]
7020 *) Makefile.tmpl was not using $CFLAGS in the link phase.
7023 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
7024 rudimentary memory debugger which can be used on live servers with
7025 low impact -- it sets all allocated and freed memory bytes to 0xa5.
7026 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
7027 and free() for each object. This is far more expensive and should
7028 only be used for testing with tools such as Electric Fence and
7029 Purify. See main/alloc.c for more details. [Dean Gaudet]
7031 *) Configure uses a sh trap and didn't set its exitcode properly.
7032 [Dean Gaudet] PR#1159
7034 *) Yet another vhost revamp. Add the NameVirtualHost directive which
7035 explicitly lists the ip:port pairs that are to be used for name-vhosts.
7036 From a given ip:port, regardless what the Host: header is, you can
7037 only reach the vhosts defined on that ip:port. The precedence of
7038 vhosts was reversed to match other precedences in the config --
7039 the earlier vhosts override the later vhosts. All vhost matching was
7040 moved into http_vhost.[ch]. [Dean Gaudet]
7042 *) ap_inline can be used to force inlining. GNUC __attribute__() can
7043 be used for whatever reason is appropriate (i.e. format() warnings
7044 for printf style functions). Both are enabled only with
7045 gcc >= 2.7.x (so that we have fewer support issues with older
7046 versions). [Dean Gaudet]
7048 *) Fix support for Proxy Authentication (we were testing the response
7049 status too early). [Marc Slemko]
7051 *) CoreDumpDirectory directive directs where the core file is
7052 written when a SIGSEGV, SIGBUS, SIGABORT or SIGABRT are
7053 received. [Marc Slemko, Dean Gaudet]
7055 *) PORT: Support for Atari MINT.
7056 [Jan Paul Schmidt <Jan.P.Schmidt@mni.fh-giessen.de>]
7058 *) When booting, apache will now detach itself from stdin, stdout,
7059 and stderr. stderr will not be detached until after the config
7060 files have been read so you will be able to see initial error
7061 messages. After that all errors are logged in the error_log.
7062 This makes it more convenient to start apache via rsh, ssh,
7063 or crontabs. [Dean Gaudet] PR#523
7065 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7066 Also removed the auto-generated link to www.apache.org that was the
7067 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7069 *) send_fb would not detect aborted connections in some situations.
7072 *) mod_include would use uninitialized data when parsing certain
7073 expressions involving && and ||. [Brian Slesinsky] PR#1139
7075 *) mod_imap should only handle GET methods. [Jay Bloodworth]
7077 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7079 *) mod_autoindex improperly counted &escapes; as more than one
7080 character in the description. It also improperly truncated
7081 descriptions that were exactly the maximum length.
7084 *) RedirectMatch was not properly escaping the result (PR#1155). Also
7085 "RedirectMatch /advertiser/(.*) $1" is now permitted.
7088 *) mod_include now uses symbolic names to check for request success
7089 and return HTTP errors, and correctly handles all types of
7090 redirections (previously it only did temporary redirect correctly).
7091 [Ken Coar, Roy Fielding]
7093 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7094 r->filename. Since those two are meant to be in sync with each other
7095 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7097 *) PORT: Support Unisys SVR4, whose uname returns mostly useless data.
7098 ["Kaufman, Steven E" <Steven.Kaufman@unisys.com>]
7100 *) Inetd mode (which is buggy) uses timeouts without having setup the
7101 jmpbuffer. [Dean Gaudet] PR#1064
7103 *) Work around problem under Linux where a child will start looping
7104 reporting a select error over and over.
7105 [Rick Franchuk <rickf@transpect.net>] PR#1107, 987, 588
7107 *) Fixed error in proxy_util.c when looping through multiple host IP
7108 addresses. [Lars Eilebrecht] PR#974
7110 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
7111 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
7112 bytes before writing, but it will never split a log entry across a
7113 buffer boundary. [Dean Gaudet]
7115 *) API: the short_score record has been split into two pieces, one which
7116 the parent writes on, and one which the child writes on. As part of
7117 this change the get_scoreboard_info() function was removed, and
7118 scoreboard_image was exported. This change fixes a race condition
7119 in file based scoreboard systems, and speeds up changes involving the
7120 scoreboard in earlier 1.3 development. [Dean Gaudet]
7122 *) API: New register_other_child() API (see http_main.h) which allows
7123 modules to register children with the parent for maintenance. It
7124 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
7126 *) API: New piped_log API (see http_log.h) which implements piped logs,
7127 and will use register_other_child to implement reliable piped logs
7128 when it is available. The reliable piped logs part can be disabled
7129 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
7130 logs is only available on Unix. [Dean Gaudet]
7132 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
7133 meets_conditions(). This allows conditional HTTP selection to be
7134 handled separately from the storing of the header fields, and provides
7135 the ability for CGIs to set their own ETags for conditional checking.
7136 [Ken Coar, Roy Fielding] PR#895
7138 *) Changes to mod_log_config to allow naming of format strings.
7139 Format nicknames are defined with "LogFormat fmt nickname", and can
7140 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
7143 *) New module, "mod_speling", which can help find files even when
7144 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
7146 *) API: New function child_terminate() triggers the child process to
7147 exit, while allowing the child finish what it needs to for the
7148 current request first.
7149 [Doug MacEachern, Alexei Kosut]
7151 *) Windows now defaults to using full status reports with mod_status.
7152 [Alexei Kosut] PR #1094
7154 *) *Really* disable all mod_rewrite operations if the engine is off.
7155 Some things (like RewriteMaps) were checked/performed even if they
7156 weren't supposed to be. [Ken Coar] PR #991
7158 *) Implement a new timer scheme which eliminates the need to call alarm() all
7159 the time. Instead a counter in the scoreboard for each child is used to
7160 show when the child has made forward progress. The parent samples this
7161 counter every scoreboard maintenance cycle, and issues SIGALRM if no
7162 progress has been made in the timeout period. This reduces the static
7163 request best-case syscall count to 22 from 29. This scheme is only
7164 used by systems with memory-based scoreboards. [Dean Gaudet]
7166 *) The proxy now properly handles CONNECT requests which are sent
7167 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
7169 *) A script called apachectl has been added to the support
7170 directory. This script allows you to do things such as
7171 "apachectl start" and "apachectl restart" from the command
7174 *) Modules and core routines are now put into libraries, which
7175 simplifies the link line tremendously (among other advantages).
7178 *) Some of the MD5 names defined in Apache have been renamed to have
7179 an `ap_' prefix to avoid conflicts with routines supplied by
7180 external libraries. [Ken Coar]
7182 *) Removal of mod_auth_msql.c from the distribution. There are many
7183 other options for databases today. Rather than offer one option,
7184 offer none at this time. mod_auth_msql and other SQL database
7185 authentication modules can be found at the Apache Module Registry.
7186 http://modules.apache.org/ It would be nice to offer a generic
7187 mod_auth_sql option in the near future.
7189 *) PORT: BeOS support added [Alexei Kosut]
7191 *) Configure no longer accepts the -make option, since it creates
7192 Makefile on the fly based on Makefile.tmpl and Configuration.
7194 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
7195 of forcibly killing off all its processes and exiting without
7196 cleaning up. [Alexei Kosut]
7198 *) API: A new field in the request_rec, r->mtime, has been added to
7199 avoid gratuitous parsing of date strings. It is intended to hold
7200 the last-modified date of the resource (if applicable). An
7201 update_mtime() routine has also been added to advance it if
7202 appropriate. [Roy Fielding, Ken Coar]
7204 *) SECURITY: If a htaccess file can not be read due to bad permissions,
7205 deny access to the directory with a HTTP_FORBIDDEN. The previous
7206 behavior was to ignore the htaccess file if it could not be read.
7207 This change may make some setups with unreadable htaccess files
7208 stop working. [Marc Slemko] PR#817
7210 *) Add aplog_error() providing a mechanism to define levels of
7211 verbosity to the server error logging. This addition also provides
7212 the ability to log errors using syslogd. Error logging is configurable
7213 on a per-server basis using the LogLevel directive. Conversion
7214 of log_*() in progress. [Randy Terbush]
7216 *) Further enhance aplog_error() to not log filename, line number, and
7217 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7219 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7220 converted to long ones. Backslashes are converted to forward
7221 slashes. Case is converted to lower. Parts of URLs that do not
7222 correspond to files are left completely alone. [Ben Laurie]
7224 *) PORT: 2 new OSs added to the list of ports:
7225 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7226 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7228 *) Add the server version (SERVER_VERSION macro) to the "server
7229 configured and running" entry in the error_log. Also build an
7230 object file at link-time that contains the current time
7231 (SERVER_BUILT global const char[]), and include that in the
7234 *) Set r->headers_out when sending responses from the proxy.
7235 This fixes things such as the logging of headers sent from
7236 the proxy. [Marc Slemko] PR#659
7238 *) support/httpd_monitor is no longer distributed because the
7239 scoreboard should not be file based if at all possible. Use
7240 mod_status to see current server snapshot.
7242 *) (set_file_slot): New function, allowing auth directives to be
7243 independent of the server root, so the server documents can be
7244 moved to a different directory or machine more easily.
7245 [David J. MacKenzie]
7247 *) If no TransferLog is given explicitly, decline
7248 to log. This supports coexistence with other logging modules,
7249 such as the custom one that UUNET uses. [David J. MacKenzie]
7251 *) Check for titles in server-parsed HTML files.
7252 Ignore leading newlines and returns in titles. The old behavior
7253 of replacing a newline after <title> with a space causes the
7254 title to be misaligned in the listing. [David J. MacKenzie]
7256 *) Change mod_cern_meta to be configurable on a per-directory basis.
7257 [David J. MacKenzie]
7259 *) Add 'Include' directive to allow inclusion of configuration
7260 files within configuration files. [Randy Terbush]
7262 *) Proxy errors on connect() are logged to the error_log (nothing
7263 new); now they include the IP address and port that failed
7264 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7266 *) Various architectures now define USE_MMAP_FILES which causes
7267 the server to use mmap() for static files. There are two
7268 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7269 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7270 number of bytes written in one cycle from a single mmap()d object,
7271 default 32768). [Dean Gaudet]
7273 *) API: Added post_read_request API phase which is run right after reading
7274 the request from a client, or right after an internal redirect. It is
7275 useful for modules setting environment variables that depend only on
7276 the headers/contents of the request. It does not run during subrequests
7277 because subrequests inherit pretty much everything from the main
7278 request. [Dean Gaudet]
7280 *) Added mod_unique_id which is used to generate a unique identifier for
7281 each hit, available in the environment variable UNIQUE_ID.
7284 *) init_modules is now called after the error logs have been opened. This
7285 allows modules to emit information messages into the error logs.
7288 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7289 information for case where proxy module is not available. [Marc Slemko]
7291 *) PORT: Apache has need for mutexes to serialize its children around
7292 accept. In prior versions either fcntl file locking or flock file
7293 locking were used. The method is chosen by the definition of
7294 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7295 and FLOCK for flock(). New options have been added:
7296 - SYSVSEM to use System V style semaphores
7297 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7298 - USLOCK to use IRIX uslock
7299 Based on timing various techniques, the following changes were made
7301 - Linux 2.x uses flock instead of fcntl
7302 - Solaris 2.x uses pthreads
7303 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7304 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7305 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7306 Martijn Koster <m.koster@pobox.com>]
7308 *) PORT: The semantics of accept/select make it very desirable to use
7309 mutexes to serialize accept when multiple Listens are in use. But
7310 in the case where only a single socket is open it is sometimes
7311 redundant to serialize accept(). Not all unixes do a good job with
7312 potentially dozens of children blocked on accept() on the same
7313 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7314 the server will avoid serialization when listening on only one socket,
7315 and use serialization when listening on multiple sockets.
7316 [Dean Gaudet] PR#467
7318 *) Configure changes: TestLib replaced by TestCompile, which has
7319 some additional capability (such as doing a sanity check of
7320 the compiler and flags selected); the version of Solaris is now
7321 available via the #define value of SOLARIS2; IRIX n32bit libs
7322 now supported and selectable by new Configuration Rule: IRIXN32;
7323 We no longer default to -O2 optimization. [Jim Jagielski]
7325 *) Updated Configure: Configuration now uses AddModule to specify
7326 module source or binary file location, relative to src directory.
7327 Modules can be dropped into modules/extra, or in their own
7328 directory, and modules can come with a Makefile or Configure can
7329 create one. Modules can add compiler or library information to
7330 generated Makefiles. [Paul Sutton]
7332 *) Source core re-organisation: distributed modules are now in
7333 modules/standard. All other source code is in main. OS-specific
7334 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7336 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7339 *) Fix another long-standing bug in sub_req_lookup_file where it would
7340 happily skip past access checks on subdirectories looked up with
7341 relative paths. (It's used by mod_dir, mod_negotiation,
7342 and mod_include.) [Dean Gaudet]
7344 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7345 N is the number of <Directory> sections, and M is the number of
7346 components in the filename of an object.
7348 To achieve this optimization the following config changes were made:
7349 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7350 <Files>s, and <Location>s now treat a slash as a special
7351 character. For example "/home/*/public_html" previously would
7352 match "/home/a/andrew/public_html", now it only matches things
7353 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7354 - It's possible now to use [] wildcarding in <Directory>, <Files>
7356 - Regex <Directory>s are applied after all non-regex <Directory>s.
7360 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7361 and corrupted paths. [Dean Gaudet]
7363 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7364 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7365 be accessed now via backreferences $1..$9 in RewriteConds test-against
7366 strings in addition to RewriteRules subst string. Second the grouped
7367 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7368 via backreferences %1..%9 both in following RewriteCond test-against
7369 strings and RewriteRules subst string. This provides maximum flexibility
7370 through the use of backreferences.
7371 Additionally the rewriting engine was cleaned up by putting common
7372 code to the new expand_backrefs_inbuffer() function.
7373 [Ralf S. Engelschall]
7375 *) When merging the main server's <Directory> and <Location> sections into
7376 a vhost, put the main server's first and the vhost's second. Otherwise
7377 the vhost can't override the main server. [Dean Gaudet] PR#717
7379 *) The <Directory> code would merge and re-merge the same section after
7380 a match was found, possibly causing problems with some modules.
7383 *) ip-based vhosts are stored and queried using a hashing function, which
7384 has been shown to improve performance on servers with many ip-vhosts.
7385 Some other changes had to be made to accommodate this:
7386 - the * address for vhosts now behaves like _default_
7387 - the matching process now is:
7388 - match an ip-vhost directly via hash (possibly matches main
7390 - if that fails, just pretend it matched the main server
7391 - if so far only the main server has been matched, perform
7392 name-based lookups (ServerName, ServerAlias, ServerPath)
7393 *only on name-based vhosts*
7394 - if they fail, look for _default_ vhosts
7395 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7397 *) dbmmanage overhaul:
7398 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7399 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7400 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7401 - provide better seed for rand
7402 - prompt for password as per getpass(3) (turn off echo, read from
7404 - use "newstyle" crypt based on $Config{osname} ($^O)
7405 - will not add a user if already in database, use new `update' command
7407 - added `check' command to check a users' password
7408 - added `import' command to convert existing password text-files or
7409 dbm files exported with `view'
7410 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7413 *) Added psocket() which is a pool form of socket(), various places within
7414 the proxy weren't properly blocking alarms while registering the cleanup
7415 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7416 was a bug where the client socket was being close()d twice due a still
7417 registered cleanup. [Dean Gaudet]
7419 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7422 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7423 [Jason Venner <jason@idiom.com>] PR#667
7425 *) Enable ``=""'' for RewriteCond directives to match against
7426 the empty string. This is the preferred way instead of ``^$''.
7427 [Ralf S. Engelschall]
7429 *) Fixed an infinite loop in mod_imap for references above the server root
7430 [Dean Gaudet] PR#748
7432 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7433 SendBufferSize, so that the TCP window can be set appropriately
7434 for LFNs. [Phillip A. Prindeville]
7436 *) mod_browser has been replaced by the more general mod_setenvif
7437 (courtesy of Paul Sutton). BrowserMatch* directives are still
7438 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7439 UnSetEnvIfZero directives. [Ken Coar]
7441 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7442 order for remote_host to be set (for logging, or for the env var
7443 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7446 *) mod_access overhaul:
7447 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7448 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7449 - Critical path was sped up by pre-computing a few things at config time.
7450 - The undocumented syntax "allow user-agents" was removed,
7451 the replacement is "allow from env=foobar" combined with mod_browser.
7452 - When used with hostnames it now forces a double-reverse lookup
7453 no matter what the directory settings are. This double-reverse
7454 doesn't affect any of the other routines that use the remote
7455 hostname. In particular it's still passed to CGIs and the log
7456 without the double-reverse check. Related PR#860.
7459 *) When a large bwrite() occurs (larger than the internal buffer size),
7460 while there is already something in the buffer, apache will combine
7461 the large write and the buffer into a single writev(). (This is
7462 in anticipation of using mmap() for reading files.)
7465 *) In obscure cases where a partial socket write occurred while chunking,
7466 Apache would omit the chunk header/footer on the next block. Cleaned
7467 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7468 a bug where a long pause in DNS lookups could cause the last packet
7469 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7471 *) API: Added child_exit function to module structure. This is called
7472 once per "heavy-weight process" just before a server child exit()'s
7473 e.g. when max_requests_per_child is reached, etc.
7474 [Doug MacEachern, Dean Gaudet]
7476 *) mod_include cleanup showed that handle_else was being used to handle
7477 endif. It didn't cause problems, but it was cleaned up too.
7480 *) mod_cern_meta would attempt to find meta files for the directory itself
7481 in some cases, but not in others. It now avoids it in all cases.
7484 *) mod_mime_magic would core dump if there was a decompression error.
7485 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7487 *) PORT: some variants of DGUX require -lsocket -lnsl
7488 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7490 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7491 by the various fields (name, size, et cetera), either in ascending
7492 or descending order. Just click on the column header. [Ken Coar]
7494 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7495 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7496 the relatively safe direction. [Dean Gaudet] PR#344
7498 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7499 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7501 *) child_main avoids an unneeded call to select() when there is only one
7502 listening socket. [Dean Gaudet]
7504 *) In the event that the server is starved for idle servers it will
7505 spawn 1, then 2, then 4, ..., then 32 servers each second,
7506 doubling each second. It'll also give a warning in the errorlog
7507 since the most common reason for this is a poor StartServers
7508 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7509 the maximum. [Dean Gaudet]
7511 *) Apache now provides an effectively unbuffered connection for
7512 CGI scripts. This means that data will be sent to the client
7513 as soon as the CGI pauses or stops output; previously, Apache would
7514 buffer the output up to a fixed buffer size before sending, which
7515 could result in the user viewing an empty page until the CGI finished
7516 or output a complete buffer. It is no longer necessary to use an
7517 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7518 in a language that by default does buffering (e.g. perl) this
7519 shouldn't have a detrimental effect on performance.
7521 "nph-" CGIs, which formerly provided a direct socket to the client
7522 without any server post-processing, were not fully compatible with
7523 HTTP/1.1 or SSL support. As such they would have had to implement
7524 the transport details, such as encryption or chunking, in order
7525 to work properly in certain situations. Now, the only difference
7526 between nph and non-nph scripts is "non-parsed headers".
7527 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7529 *) If a BUFF is switched from buffered to unbuffered reading the first
7530 bread() will return whatever remained in the buffer prior to the
7531 switch. [Dean Gaudet]
7533 Changes with Apache 1.3a1
7535 *) Added another Configure helper script: TestLib. It determines
7536 if a specified library exists. [Jim Jagielski]
7538 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7539 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7542 *) PORT: Some architectures use size_t for various lengths in network
7543 functions such as accept(), and getsockname(). The definition
7544 NET_SIZE_T is used to control this. [Dean Gaudet]
7546 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7547 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7548 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7550 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7551 [Igor N Kovalenko <infoh@mail.wplus.net>]
7553 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7554 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7555 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7556 [Dean Gaudet] related PR#875
7558 *) API: Correct child_init() slot declaration from int to void, to
7559 match the init() declaration. Update mod_example to use the new
7562 *) added transport handle slot (t_handle) to the BUFF structure
7565 *) get_client_block() returns wrong length if policy is
7566 REQUEST_CHUNKED_DECHUNK.
7567 [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#815
7569 *) Support the image map format of FrontPage. For example:
7570 rect /url.hrm 10 20 30 40
7571 ["Chris O'Byrne" <obyrne@iol.ie>] PR#807
7573 *) PORT: -lresolv and -lsocks were in the wrong order for Solaris.
7574 ["Darren O'Shaughnessy" <darren@aaii.oz.au>] PR#846
7576 *) AddModuleInfo directive for mod_info which allows you to annotate
7577 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7579 *) Added NoProxy directive to avoid using ProxyRemote for selected
7580 addresses. Added ProxyDomain directive to cause unqualified
7581 names to be qualified by redirection.
7582 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7584 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7585 header to the remote host in the proxy. [Sameer Parekh and
7588 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7589 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7590 URLs, fixed rewritelog(), fixed forced response code handling on
7591 redirects from within .htaccess files, disabled pipe locking under
7592 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7593 no substitution, bugfixed situations where HostnameLookups is off, made
7594 mod_rewrite more thread-safe for NT port and fixed problem when creating
7595 an empty query string via "xxx?".
7596 This update also removes the copyright of Ralf S. Engelschall,
7597 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7598 exclusively copyrighted by the Apache Group now. This happened because
7599 the author now has gifted mod_rewrite exclusively to the Apache Group and
7600 no longer maintains an external version.
7601 [Ralf S. Engelschall]
7603 *) API: Added child_init function to module structure. This is called
7604 once per "heavy-weight process" before any requests are handled.
7605 See http_config.h for more details. [Dean Gaudet]
7607 *) Anonymous_LogEmail was logging on each subrequest.
7608 [Dean Gaudet] PR#421, 868
7610 *) API: Added is_initial_req() which tests if the request being
7611 processed is the initial request, or a subrequest.
7614 *) Extended SSI (mod_include) now handles additional relops for
7615 string comparisons (<, >, <=, and >=). [Bruno Wolff III] PR#41
7617 *) Configure fixed to correctly propagate user-selected options and
7618 settings (such as CC and OPTIM) to Makefiles other than
7619 src/Makefile (notably support/Makefile). [Ken Coar] PR#666, #834
7621 *) IndexOptions SuppressHTMLPreamble now causes the actual HTML of
7622 directory indices to start with the contents of the HeaderName file
7623 if there is one. If there isn't one, the behaviour is unchanged.
7624 [Ken Coar, Roy Fielding, Andrey A. Chernov]
7626 *) WIN32: Modules can now be dynamically loaded DLLs using the
7627 LoadModule/LoadFile directives. Note that module DLLs must be
7628 compiled with the multithreaded DLL version of the runtime library.
7629 [Alexei Kosut and Ben Laurie]
7631 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7632 This allows the admin to completely remove automatic indexing
7633 from the server, while still supporting the basic functions of
7634 trailing-slash redirects and DirectoryIndex files. Note that if
7635 you're carrying over an old Configuration file and you use directory
7636 indexing then you'll want to add:
7638 Module autoindex_module mod_autoindex.o
7640 before mod_dir in your Configuration. [Dean Gaudet]
7642 *) popendir/pclosedir created to properly protect directory scanning.
7643 [Dean Gaudet] PR#525
7645 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7646 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7647 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7650 *) The AccessFileName directive can now take more than one filename.
7651 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7653 *) The new mod_mime_magic can be used to "magically" determine the type
7654 of a file if the extension is unknown. Based on the unix file(1)
7655 command. [Ian Kluft <ikluft@cisco.com>]
7657 *) We now determine and display the time spent processing a
7658 request if desired. [Jim Jagielski]
7660 *) mod_status: PID field of "dead" child slots no longer displays
7661 main httpd process's PID. [Jim Jagielski]
7663 *) Makefile.nt added - to build all the bits from the command line:
7664 nmake -f Makefile.nt
7665 Doesn't yet work properly. [Ben Laurie]
7667 *) Default text of 404 error is now "Not Found" rather than the
7668 potentially misleading "File Not Found". [Ken Coar]
7670 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7671 for the net if we require people that actually need this data to
7672 enable it. [Linus Torvalds]
7674 *) directory_walk() is an expensive function, keep a little more state to
7675 avoid needless string counting. Add two new functions make_dirstr_parent
7676 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7677 The new functions are a little less general than make_dirstr, but
7678 work more efficiently (less memory, less string counting).
7681 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7682 to LDFLAGS) to avoid complications with lex rules in make files.
7683 [Dean Gaudet] PR#372
7685 *) run_method optimized to avoid needless scanning over NULLs in the
7686 module list. [Dean Gaudet]
7688 *) Revamp of (unix) scoreboard management code such that it avoids
7689 unnecessary traversals of the scoreboard on each hit. This is
7690 particularly important for high volume sites with a large
7691 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7692 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7693 httpd.h. [Dean Gaudet]
7695 *) In configurations using multiple Listen statements it was possible for
7696 busy sockets to starve other sockets of service. [Dean Gaudet]
7698 *) Added hook so standalone_main can be replaced at compile time
7699 (define STANDALONE_MAIN)
7702 *) Lowest-level read/write functions in buff.c will be replaced with
7703 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7704 compile time. The default sfio discipline will behave as apache
7705 would without sfio compiled in.
7708 *) Enhance UserDir directive (mod_userdir) to accept a list of
7709 usernames for the 'disable' keyword, and add 'enable user...' to
7710 selectively *en*able userdirs if they're globally disabled.
7713 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7714 will work with Netscape dbm files. (dbmmanage will probably not
7715 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7717 *) Add a ListenBacklog directive to control the backlog parameter
7718 passed to listen(). Also change the default to 511 from 512.
7721 *) API: A new handler response DONE which informs apache that the
7722 request has been handled and it can finish off quickly, similar to
7723 how it handles errors. [Rob Hartill]
7725 *) Turn off chunked encoding after sending terminating chunk/footer
7726 so that we can't do it twice by accident. [Roy Fielding]
7728 *) mod_expire also issues Cache-Control: max-age headers.
7731 *) API: Added kill_only_once option for free_proc_chain so that it won't
7732 aggressively try to kill off specific children. For fastcgi.
7733 [Stanley Gambarin <gambarin@OpenMarket.com>]
7735 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7737 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7738 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7739 attributes in the FancyIndexing IMG tags. [Ken Coar]
7741 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7743 *) PORT: Added Windows NT support
7744 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7746 Changes with Apache 1.2.6
7748 *) mod_include when using XBitHack Full would send ETags in addition to
7749 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7750 [Dean Gaudet] PR#1133
7752 *) SECURITY: When a client connects to a particular port/addr, and
7753 gives a Host: header ensure that the virtual host requested can
7754 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7756 *) Support virtual hosts with wildcard port and/or multiple ports
7757 properly. [Ed Korthof <ed@organic.com>]
7759 *) Fixed some case-sensitivity issues according to RFC2068.
7762 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7763 and mod_include.c. [Dean Gaudet]
7765 *) Variable 'cwd' was being used pointlessly before being set.
7768 *) SIGURG doesn't exist on all platforms.
7769 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7771 *) When an error occurs during a POST, or other operation with a
7772 request body, the body has to be read from the net before allowing
7773 a keepalive session to continue. [Roy Fielding] PR#1399
7775 *) When an error occurs in fcntl() locking suggest the user look up
7776 the docs for LockFile. [Dean Gaudet]
7778 *) table_set() and table_unset() did not deal correctly with
7779 multiple occurrences of the same key. [Stephen Scheck
7780 <sscheck@infonex.net>, Ben Laurie] PR#1604
7782 *) send_fd_length() did not calculate total_bytes_sent properly in error
7783 cases. [Ben Reser <breser@regnow.com>] PR#1366
7785 *) r->connection->user was allocated in the wrong pool causing corruption
7786 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7788 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7789 Also removed the auto-generated link to www.apache.org that was the
7790 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7792 *) Multiple "close" tokens may have been set in the "Connection"
7793 header, not an error, but a waste.
7794 [Ronald.Tschalaer@psi.ch] PR#1683
7796 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7797 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7799 *) It appears the "257th byte" bug (see
7800 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7801 at the 256th byte as well. Fixed. [Dean Gaudet]
7803 *) mod_rewrite would not handle %3f properly in some situations.
7806 *) Apache could generate improperly chunked HTTP/1.1 responses when
7807 the bputc() or rputc() functions were used by modules (such as
7808 mod_include). [Dean Gaudet]
7810 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7811 some ports. [Ralf Engelschall]
7813 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7815 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7817 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7819 Changes with Apache 1.2.5
7821 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7822 only an issue on systems without a MAXDNAME define or where
7823 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7825 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7828 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7829 directory listings. [Marc Slemko]
7831 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7834 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7835 is used to read various types of files such as htaccess and
7836 htpasswd files. [Marc Slemko]
7838 *) SECURITY: Ensure that the buffer returned by ht_time is always
7839 properly null terminated. [Marc Slemko]
7841 *) SECURITY: General mod_include cleanup, including fixing several
7842 possible buffer overflows and a possible infinite loop. This cleanup
7843 was done against 1.3 code and then backported to 1.2, the result
7844 is a large difference (due to indentation cleanup in 1.3 code).
7845 Users interested in seeing a smaller set of relevant differences
7846 should consider comparing against src/modules/standard/mod_include.c
7847 from the 1.3b3 release. Non-indentation changes to mod_include
7848 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7850 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7851 including fixing a possible buffer overflow. This cleanup also
7852 was done with 1.3 code as a basis, see the the previous note
7853 about mod_include. [Dean Gaudet]
7855 *) SECURITY: If a htaccess file can not be read due to bad
7856 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7857 The previous behavior was to ignore the htaccess file if it could not
7858 be read. This change may make some setups with unreadable
7859 htaccess files stop working. PR#817 [Marc Slemko]
7861 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7862 Make it O(n). This inefficiency could be used to mount a denial
7863 of service attack against the Apache server. Thanks to
7864 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
7867 *) mod_include used uninitialized data for some uses of && and ||.
7868 [Brian Slesinsky <bslesins@wired.com>] PR#1139
7870 *) mod_imap should decline all non-GET methods.
7871 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7873 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7875 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7876 r->filename. Since those two are meant to be in sync with each other
7877 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7879 *) mod_include did not properly handle all possible redirects from sub-
7880 requests. [Ken Coar]
7882 *) Inetd mode (which is buggy) uses timeouts without having setup the
7883 jmpbuffer. [Dean Gaudet] PR#1064
7885 *) Work around problem under Linux where a child will start looping
7886 reporting a select error over and over.
7887 [Rick Franchuk <rickf@transpect.net>] PR#1107
7889 Changes with Apache 1.2.4
7891 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7892 always making requests with the full-URI instead of just the URI path.
7893 [Marc Slemko, Roy Fielding]
7895 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7896 on this platform. [Marc Slemko]
7898 Changes with Apache 1.2.3
7900 *) The request to a remote proxy was mangled if it was generated as the
7901 result of a ProxyPass directive. URL schemes other than http:// were not
7902 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7903 PR#812 [Lars Eilebrecht]
7905 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7906 information for case where proxy module is not available. [Marc Slemko]
7908 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7909 do for errors and cached responses. [Roy Fielding]
7911 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7913 Changes with Apache 1.2.2 [not released]
7915 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7916 happily skip past access checks on subdirectories looked up with relative
7917 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7920 *) Add lockfile name to error message printed out when
7921 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7924 *) Enhanced the chunking and error handling inside the buffer functions.
7925 [Dean Gaudet, Roy Fielding]
7927 *) When merging the main server's <Directory> and <Location> sections into
7928 a vhost, put the main server's first and the vhost's second. Otherwise
7929 the vhost can't override the main server. [Dean Gaudet] PR#717
7931 *) The <Directory> code would merge and re-merge the same section after
7932 a match was found, possibly causing problems with some modules.
7935 *) Fixed an infinite loop in mod_imap for references above the server root.
7936 [Dean Gaudet] PR#748
7938 *) mod_include cleanup showed that handle_else was being used to handle
7939 endif. It didn't cause problems, but it was cleaned up too.
7942 *) Last official synchronization of mod_rewrite with author version (because
7943 mod_rewrite is now directly developed by the author at the Apache Group):
7944 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7945 minus WIN32/NT stuff, but plus copyright removement.
7947 - workaround for detecting infinite rewriting loops
7948 - fixed setting of env vars when "-" is used as subst string
7949 - fixed forced response code on redirects (PR#777)
7950 - fixed cases where r->args is ""
7951 - kludge to disable locking on pipes under braindead SunOS
7952 - fix for rewritelog in cases where remote hostname is unknown
7953 - fixed totally damaged request_rec walk-back loop
7954 o remove static from local data and add static to global ones.
7955 o replaced ugly proxy finding stuff by simple
7956 find_linked_module("mod_proxy") call.
7957 o added missing negation char on rewritelog()
7958 o fixed a few comment typos
7959 [Ralf S. Engelschall]
7961 *) Anonymous_LogEmail was logging on each subrequest.

7964 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7965 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7966 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7967 Additionally mod_browser now triggers during translate_name to workaround
7968 a deficiency in the header_parse phase.

7985 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7986 under Solaris 2.x (up through 2.5.1). It has been fixed.
7987 [Dean Gaudet] PR#832
7989 *) API: In HTTP/1.1, whether or not a request message contains a body
7990 is independent of the request method and based solely on the presence
7991 of a Content-Length or Transfer-Encoding. Therefore, our default
7992 handlers need to be prepared to read a body even if they don't know
7993 what to do with it; otherwise, the body would be mistaken for the
7994 next request on a persistent connection. discard_request_body()
7995 has been added to take care of that. [Roy Fielding] PR#378
7997 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7998 release version number, such that it always increases along the
7999 same lines as our source code branching. [Roy Fielding]
8001 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
8003 Changes with Apache 1.2.1
8005 *) SECURITY: Don't serve file system objects unless they are plain files,
8006 symlinks, or directories. This prevents local users from using pipes
8007 or named sockets to invoke programs for an extremely crude form of
8010 *) SECURITY: HeaderName and ReadmeName were settable in .htaccess and
8011 could contain "../" allowing a local user to "publish" any file on
8012 the system. No slashes are allowed now. [Dean Gaudet]
8014 *) SECURITY: It was possible to violate the symlink Options using mod_dir
8015 (headers, readmes, titles), mod_negotiation (type maps), or
8016 mod_cern_meta (meta files). [Dean Gaudet]
8018 *) SECURITY: Apache will refuse to run as "User root" unless
8019 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
8021 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
8022 if it contained a .htaccess disallowing symlinks. This is contrary
8023 to the rule that symlink permissions are tested with the symlink
8024 options of the parent directory. [Dean Gaudet] PR#353
8026 *) CONFIG: The LockFile directive can be used to place the serializing
8027 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
8028 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
8031 *) Request processing now retains state of whether or not the request
8032 body has been read, so that internal redirects and subrequests will
8033 not try to read it twice (and block). [Roy Fielding]
8035 *) Add a placeholder in modules/Makefile to avoid errors with certain
8036 makes. [Marc Slemko]
8038 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.
8039 [Dean Gaudet] PR#644
8041 *) mod_include was not properly changing the current directory.
8042 [Marc Slemko] PR#742
8044 *) Attempt to work around problems with third party libraries that do not
8045 handle high numbered descriptors (examples include bind, and
8046 solaris libc). On all systems apache attempts to keep all permanent
8047 descriptors above 15 (called the low slack line). Solaris users
8048 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
8049 which keeps all non-FILE * descriptors above 255. On all systems
8050 this should make supporting large numbers of vhosts with many open
8051 log files more feasible. If this causes trouble please report it,
8052 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
8053 [Dean Gaudet] various PRs
8055 *) Related to the last entry, network sockets are now opened before
8056 log files are opened. The only known case where this can cause
8057 problems is under Solaris with many virtualhosts and many Listen
8058 directives. But using -DHIGH_SLACK_LINE=256 described above will
8059 work around this problem. [Dean Gaudet]
8061 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
8064 *) Improved unix error response logging. [Marc Slemko]
8066 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
8067 QSA=query_string_append. Also fixed a nasty bug in per-dir context:
8068 when a URL http://... was used in conjunction with a special

8114 reading from one buffer and writing to another, at least until it has
8115 a custom timeout handler. [Roy Fielding and Petr Lampa]
8117 *) Fixed problem on IRIX with servers hanging in IdentityCheck,
8118 apparently due to a mismatch between sigaction and setjmp.
8119 [Roy Fielding] PR#502

8122 or if we received a request-line that was too long to process (414).

8125 *) Virtual hosts with the same ServerName, but on different ports, were
8126 not being selected properly. [Ed Korthof]

8130 change submitted by Jozsef Hollosi <hollosi@sbcm.com>.
8131 [Chuck Murcko] PR#614
8133 *) If multiple requests on a single connection are used to retrieve
8134 data from different virtual hosts, the virtual host list would be
8135 scanned starting with the most recently used VH instead of the first,
8136 causing most virtual hosts to be ignored.

8139 *) The OS/2 handling of process group was broken by a porting patch for
8140 MPE, so restored prior code for OS/2. [Roy Fielding and Garey Smiley]

8146 has found matching variants, but none are acceptable, return the
8147 negotiation result if there are no more DirectoryIndex names to lookup.
8148 [Petr Lampa and Roy Fielding]
8150 *) If a soft_timeout occurs after keepalive is set, then the main child
8151 loop would try to read another request even though the connection
8152 has been aborted. [Roy Fielding]
8154 *) Configure changes: Allow for whitespace at the start of a
8155 Module declaration. Also, be more understanding about the
8156 CC=/OPTIM= format in Configuration. Finally, fix compiler
8157 flags if using HP-UX's cc compiler. [Jim Jagielski]
8159 *) Subrequests and internal redirects now inherit the_request from the
8160 original request-line. [Roy Fielding]
8162 *) Test for error conditions before creating output header fields, since
8163 we don't want the error message to include those fields. Likewise,
8164 reset the content_language(s) and content_encoding of the response
8165 before generating or redirecting to an error message, since the new
8166 message will have its own Content-* definitions. [Dean Gaudet]
8168 *) Restored the semantics of headers_out (headers sent only with 200..299
8169 and 304 responses) and err_headers_out (headers sent with all responses).
8170 Avoid the overhead of copying tables if err_headers_out is empty
8171 (the usual case). [Roy Fielding]
8173 *) Fixed a couple places where a check for the default Content-Type was
8174 not properly checking both the value configured by the DefaultType
8175 directive and the DEFAULT_TYPE symbol in httpd.h. Changed the value
8176 of DEFAULT_TYPE to match the documented default (text/plain).
8177 [Dean Gaudet] PR#506
8179 *) Escape the HTML-sensitive characters in the Request-URI that is
8180 output for each child by mod_status. [Dean Gaudet and Ken Coar] PR#501
8182 *) Properly initialize the flock structures used by the mutex locking
8183 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
8186 *) The method for determining PATH_INFO has been restored to the pre-1.2b
8187 (and NCSA httpd) definition wherein it was the extra path info beyond
8188 the CGI script filename. The environment variable FILEPATH_INFO has
8189 been removed, and instead we supply the original REQUEST_URI to any
8190 script that wants to be Apache-specific and needs the real URI path.
8191 This solves a problem with existing scripts that use extra path info
8192 in the ScriptAlias directive to pass options to the CGI script.
8195 *) The _default_ change in 1.2b10 will change the behaviour on configs
8196 that use multiple Listen statements for listening on multiple ports.
8197 But that change is necessary to make _default_ consistent with other
8198 forms of <VirtualHost>. It requires such configs to be modified
8199 to use <VirtualHost _default_:*>. The documentation has been
8200 updated. [Dean Gaudet] PR#530
8202 *) If an ErrorDocument CGI script is used to respond to an error
8203 generated by another CGI script which has already read the message
8204 body of the request, the server would block trying to read the
8205 message body again. [Rob Hartill]
8207 *) signal() replacement conflicted with a define on QNX (and potentially
8208 other platforms). Fixed. [Ben Laurie] PR#512
8210 Changes with Apache 1.2b10
8212 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
8213 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8215 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8217 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]

8221 [Chuck Murcko] PR #491
8223 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8224 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8226 Changes with Apache 1.2b9 [never announced]
8228 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8229 changes and in anticipation of 1.2 final release. [Roy Fielding]
8231 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8232 the connection (e.g., when user presses Stop). Apache will now stop
8233 trying to send a message body immediately after an error from write.
8234 [Roy Fielding and Nathan Kurz] PR#335
8236 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8237 than mod_alias, and mod_alias has higher priority than mod_proxy;
8238 rearranged other modules to enhance understanding of their purpose
8239 and relative order (and maybe even reduce some overhead).
8240 [Roy Fielding and Sameer Parekh]
8242 *) Fix graceful restart. Eliminate many signal-related race
8243 conditions in both forms of restart, and in SIGTERM. See
8244 htdocs/manual/stopping.html for details on stopping and
8245 restarting the parent. [Dean Gaudet]
8247 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8248 memory allocator to avoid a behaviour that required extra blocks to
8249 be allocated. [Dean Gaudet]
8251 *) Allow suexec to access files relative to current directory but not
8252 above. (Excluding leading / or any .. directory.) [Ken Coar]
8255 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8256 PR#367, 368, 354, 453
8258 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8259 while obtaining the /~user and save the username in a separate data
8260 area so that it won't be overwritten by the call to getgrgid(), and
8261 fix some misuse of the pool string allocation functions. Also fixes
8262 a general problem with parsing URL query info into args for CGI scripts.

8270 AuthDBAuthoritative. [Marc Slemko] PR#420
8272 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8274 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8275 object that can't be PUT, or FOOBAR for some method FOOBAR that
8276 apache doesn't know about at all). Log 404s that occur in mod_include.
8277 [Paul Sutton, John Van Essen]
8279 *) If a soft timeout (or lingerout) occurs while trying to flush a
8280 buffer or write inside buff.c or fread'ing from a CGI's output,
8281 then the timeout would be ignored. [Roy Fielding] PR#373
8283 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8284 parsing of headers. If the terminating empty-line CRLF occurs starting
8285 at the 256th or 257th byte of output, then Navigator will think a normal
8286 image is invalid. We are guessing that this is because their initial
8287 read of a new request uses a 256 byte buffer. We check the bytes written
8288 so far and, if we are about to tickle the bug, we instead insert a
8289 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8291 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8292 of an external redirection. [Roy Fielding and Paul Sutton]
8294 *) Configure would create a broken Makefile if the configuration file
8295 contained a commented-out Rule. [Roy Fielding]
8297 *) Promote per_dir_config and subprocess_env from the subrequest to the
8298 main request in mod_negotiation. In particular this fixes a bug
8299 where <Files> sections wouldn't properly apply to negotiated content.
8302 *) Fix a potential deadlock in mod_cgi script_err handling.
8303 [Ralf S. Engelschall]
8305 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8308 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8309 .htaccess files because the RewriteBase was not replaced correctly.
8310 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8311 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8313 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8314 1.x the settings are those of pre-1.2b8. For 2.x we include
8315 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8316 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8317 [Dean Gaudet] PR#336, PR#340
8319 *) Redirect did not preserve ?query_strings when present in the client's
8320 request. [Dean Gaudet]
8322 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8324 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8326 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8328 *) Add mod_example (illustration of API techniques). [Ken Coar]
8330 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8332 *) Improve handling of directories when filenames have spaces in them.
8335 *) For hosts with multiple IP addresses, try all additional addresses if
8336 necessary to get a connect. Fail only if hostent address list is
8337 exhausted. [Chuck Murcko]
8339 *) More signed/unsigned port fixes. [Dean Gaudet]
8341 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8344 Changes with Apache 1.2b8
8346 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8347 to it. [Marc Slemko]
8349 *) The addition of <Location> and <File> directives made the
8350 sub_req_lookup_simple() function bogus, so we now handle
8351 the special cases directly. [Dean Gaudet]
8353 *) We now try to log where the server is dumping core when a fatal
8354 signal is received. [Ken Coar]
8356 *) Improved lingering_close by adding a special timeout, removing the
8357 spurious log messages, removing the nonblocking settings (they
8358 are not needed with the better timeout), and adding commentary
8359 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8360 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8362 *) Send error messages about setsockopt failures to the server error
8363 log instead of stderr. [Roy Fielding]
8365 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8367 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8368 processing a subrequest, allocate memory from r->main->pool instead
8369 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8370 in the middle of an SSI request. [Dean Gaudet] PR #122
8372 *) Fixed status of response when POST is received for a nonexistent URL
8373 (was sending 405, now 404) and when any method is sent with a
8374 full-URI that doesn't match the server and the server is not acting
8375 as a proxy (was sending 501, now 403). [Roy Fielding]
8377 *) Host port changed to unsigned short. [Ken Coar] PR #276
8379 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8381 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8383 *) Report extra info from errno with many errors that cause httpd to exit.
8384 spawn_child, popenf, and pclosef now have valid errno returns in the
8385 event of an error. Correct problems where errno was stomped on
8386 before being reported. [Dean Gaudet]
8388 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8389 never called, and thus the filesystem would remain full indefinitely.
8390 We now also remove incomplete cache files left if the origin server
8391 didn't send a Content-Length header and either the client has aborted
8392 transfer or bwrite() to client has failed. [Petr Lampa]
8394 *) Fixed the handling of module and script-added header fields.
8395 Improved the interface for sending header fields and reduced
8396 the duplication of code between sending okay responses and errors.
8397 We now always send both headers_out and err_headers_out, and
8398 ensure that the server-reserved fields are not being overridden,
8399 while not overriding those that are not reserved. [Roy Fielding]
8401 *) Moved transparent content negotiation fields to err_headers_out
8402 to reflect above changes. [Petr Lampa]
8404 *) Fixed the determination of whether or not we should make the
8405 connection persistent for all of the cases where some other part
8406 of the server has already indicated that we should not. Also
8407 improved the ordering of the test so that chunked encoding will
8408 be set whenever it is desired instead of only when KeepAlive
8409 is enabled. Added persistent connection capability for most error
8410 responses (those that do not indicate a bad input stream) when
8411 accessed by an HTTP/1.1 client. [Roy Fielding]
8413 *) Added missing timeouts for sending header fields, error responses,
8414 and the last chunk of chunked encoding, each of which could have
8415 resulted in a process being stuck in write forever. Using soft_timeout
8416 requires that the sender check for an aborted connection rather than
8417 continuing after an EINTR. Timeouts that used to be initiated before
8418 send_http_header (and never killed) are now initiated only within or
8419 around the routines that actually do the sending, and not allowed to
8420 propagate above the caller. [Roy Fielding]
8422 *) mod_auth_anon required an @ or a . in the email address, not both.
8425 *) per_dir_defaults weren't set correctly until directory_walk for
8426 name-based vhosts. This fixes an obscure bug with the wrong config
8427 info being used for vhosts that share the same ip as the server.
8430 *) Improved generation of modules/Makefile to be more generic for
8431 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8433 *) Generate makefile dependency for Configuration based on the actual
8434 name given when running the Configure process. [Dean Gaudet]
8436 *) Fixed problem with vhost error log not being set prior to
8437 initializing virtual hosts. [Dean Gaudet]
8439 *) Fixed infinite loop when a trailing slash is included after a type map
8440 file URL (extra path info). [Petr Lampa]
8442 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8444 *) Add documentation for DNS issues (reliability and security), and try
8445 to explain the virtual host matching process. [Dean Gaudet]
8447 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8448 fails while parsing the configuration file. [Dean Gaudet]
8450 *) Improved calls to setsockopt. [Roy Fielding]
8452 *) Negotiation changes: Don't output empty content-type in variant list;
8453 Output charset in variant list; Return sooner from handle_multi() if
8454 no variants found; Add handling of '*' wildcard in Accept-Charset.
8455 [Petr Lampa and Paul Sutton]
8457 *) Fixed overlaying of request/sub-request notes and headers in
8458 mod_negotiation. [Dean Gaudet]
8460 *) If two variants' charset quality are equal and one is the default
8461 charset (iso-8859-1), then prefer the variant that was specifically
8462 listed in Accept-Charset instead of the default. [Petr Lampa]
8464 *) Memory allocation problem in push_array() -- it would corrupt memory
8465 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8467 *) invoke_handler() doesn't handle mime arguments in content-type
8470 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8473 *) Fixed problem with ErrorDocument not working for virtual hosts
8474 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8476 *) Log an error message if we get a request header that is too long,
8477 since it may indicate a buffer overflow attack. [Marc Slemko]
8479 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8480 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8481 [Ken Coar] PR #146, #187

8493 and what is the main server, resulting in access to something
8494 other than the name defined in the virtualhost directive (but
8495 with the same IP address) failing. [Dean Gaudet]
8497 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8498 AIX; improves the redirection stuff to enable the users to generally
8499 redirect to http, https, gopher and ftp; added TIME variable for
8500 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8501 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8502 can be used in conjunction with %{TIME} or other variables to create
8503 time-dependent rewriting rules. [Ralf S. Engelschall]
8505 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8506 Module authors may need to adjust their code for proper cleanup to take
8507 place (that is, call note_cleanups_for_fd()). This change fixes problems
8508 with file descriptors being erroneously closed when the proxy module was
8509 in use. [Ben Laurie]
8511 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8512 initgroups() to hose the group information needed for later
8513 comparisons. [Randy Terbush]
8515 *) Remove unnecessary call to va_end() in create_argv() which
8516 caused a SEGV on some systems.
8518 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8521 *) Clear memory allocated for listeners. [Randy Terbush]
8523 *) Improved handling of IP address as a virtualhost address and
8524 introduced "_default_" as a synonym for the default vhost config.
8525 [Dean Gaudet] PR #212
8527 Changes with Apache 1.2b7
8529 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
8531 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
8533 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8534 - replace protocol response numbers with symbols
8535 - save variant-list into main request notes
8536 - free allocated memory from subrequests
8537 - merge notes, headers_out and err_headers_out
8539 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8540 "HTTP/#.# ###*" to be more lenient about what we accept.
8543 *) more proxy FTP bug fixes:
8544 - Changed send_dir() to remove user/passwd from displayed URL.
8545 - Changed login error messages to be more descriptive.
8546 - remove setting of SO_DEBUG socket option
8547 - Make ftp_getrc() more lenient about multiline responses,
8548 specifically, 230 responses which don't have continuation 230-
8549 on each line). These seem to be all NT FTP servers, and while
8550 perhaps questionable, they appear to be legal by RFC 959.
8551 - Add missing kill_timeout() after transfer to user completes.
8554 *) Fixed problem where a busy server could hang when restarting
8555 after being sent a SIGHUP due to child processes not exiting.
8558 *) Modify mod_include escaping so a '\' only signifies an escaped
8559 character if the next character is one that needs
8560 escaping. [Ben Laurie]
8562 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8563 used with a 'base' directive that does not have a '/' in it.
8564 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8566 *) Reduced the default timeout from 1200 seconds to 300, and the
8567 one in the sample configfile from 400 to 300. [Marc Slemko]
8569 *) Stop vbprintf from crashing if given a NULL string pointer;
8570 print (null) instead. [Ken Coar]
8572 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8573 [Marc Slemko and Roy Fielding]
8575 *) Fixed problem with mod_cgi-generated internal redirects trying to
8576 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8578 *) Reduced timeout on lingering close, removed possibility of a blocked
8579 read causing the child to hang, and stopped logging of errors if
8580 the socket is not connected (reset by client). [Roy Fielding]
8582 *) Rearranged main child loop to remove duplication of code in
8583 select/accept and keep-alive requests, fixed several bugs regarding
8584 checking scoreboard_image for exit indication and failure to
8585 account for all success conditions and trap all error conditions,
8586 prevented multiple flushes before closing the socket; close the entire
8587 socket buffer instead of just one descriptor, prevent logging of
8588 EPROTO and ECONNABORTED on platforms where supported, and generally
8589 improved readability. [Roy Fielding]
8591 *) Extensive performance improvements. Cleaned up inefficient use of
8592 auto initializers, multiple is_matchexp calls on a static string,
8593 and excessive merging of response_code_strings. [Dean Gaudet]
8595 *) Added double-buffering to mod_include to improve performance on
8596 server-side includes. [Marc Slemko]
8598 *) Several fixes for suexec wrapper. [Randy Terbush]
8599 - Make wrapper work for files on NFS filesystem.
8600 - Fix portability problem of MAXPATHLEN.
8601 - Fix array overrun problem in clean_env().
8602 - Fix allocation of PATH environment variable
8604 *) Removed extraneous blank line is description of mod_status chars.
8607 *) Logging of errors from the call_exec routine simply went nowhere,
8608 since the logfile fd has been closed, so now we send them to stderr.
8609 [Harald T. Alvestrand]
8611 *) Fixed core dump when DocumentRoot is a CGI.
8612 [Ben Laurie, reported by geddis@tesserae.com]
8614 *) Fixed potential file descriptor leak in mod_asis; updated it and
8615 http_core to use pfopen/pfclose instead of fopen/fclose.
8616 [Randy Terbush and Roy Fielding]
8618 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8619 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8620 [Dean Gaudet and Ken Coar]
8622 *) Return a 302 response code to the client when sending a redirect
8623 due to a missing trailing '/' on a directory instead of a 301; now
8624 it is cacheable. [Markus Gyger]
8626 *) Fix condition where, if a bad directive occurs in .htaccess, and
8627 sub_request() goes first to this directory, then log_reason() will
8628 SIGSEGV because it doesn't have initialized r->per_dir_config.
8629 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8631 *) Fix handling of lang_index in is_variant_better(). This was
8632 causing problems which resulted in the server sending the
8633 wrong language document in some cases. [Petr Lampa]
8635 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8636 the clean environment on some systems.
8638 *) Tweak byteserving code (e.g. serving PDF files) to work around
8639 bugs in Netscape Navigator and Microsoft Internet Explorer.
8640 Emit Content-Length header when sending multipart/byteranges.
8643 *) Port to HI-UX/WE2. [Nick Maclaren]
8645 *) Port to HP MPE operating system for HP 3000 machines
8646 [Mark Bixby <markb@cccd.edu>]
8648 *) Fixed bug which caused a segmentation fault if only one argument
8649 given to RLimit* directives. [Ed Korthof]
8651 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8653 *) Improved buffered output to the client by delaying the flush decision
8654 until the BUFF code is actually about to read the next request.
8655 This fixes a problem introduced in 1.2b5 with clients that send
8656 an extra CRLF after a POST request. Also improved chunked output
8657 performance by combining writes using writev() and removing as
8658 many bflush() calls as possible. NOTE: Platforms without writev()
8659 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8660 or Configure, unless we have already done so. [Dean Gaudet]
8662 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8664 *) Fixed mod_info output corruption bug introduced by buffer overflow
8665 fixes. [Dean Gaudet]
8667 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8668 for the special case of a 304 response. [Paul Sutton]
8670 *) Improved handling of TRACE method by bypassing normal method handling
8671 and header parsing routines; fixed Allow response to always allow TRACE.
8674 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8676 *) Cleaned-up some of the generated HTML. [Ken Coar]
8678 Changes with Apache 1.2b6
8680 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8682 *) Fix typo introduced in fix for potential infinite loop around
8683 accept() in child_main(). This change caused the rev to 1.2b6.
8684 1.2b5 was never a public beta.
8686 Changes with Apache 1.2b5
8688 *) Change KeepAlive semantics (On|Off instead of a number), add
8689 MaxKeepAliveRequests directive. [Alexei Kosut]
8691 *) Various NeXT compilation patches, as well as a change in
8692 regex/regcomp.c since that file also used a NEXT define.
8695 *) Allow * to terminate the end of a directory match in mod_dir.
8696 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8698 *) Don't call can_exec() if suexec_enabled. Calling this requires
8699 scripts executed by the suexec wrapper to be world executable, which
8700 defeats one of the advantages of running the wrapper. [Randy Terbush]
8702 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8705 *) Migration from sprintf() to snprintf() to avoid buffer
8706 overflows. [Marc Slemko]
8708 *) Provide portable snprintf() implementation (ap_snprintf)
8709 as well as *cvt family. [Jim Jagielski]
8711 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8714 *) Remove mod_fastcgi.c from the distribution. This module appears
8715 to be maintained more through the Open Market channels and should
8716 continue to be easily available at http://www.fastcgi.com/
8718 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8719 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8721 *) mod_info assumed that the config files were relative to ServerRoot.
8724 *) CGI scripts called as an error document resulting from failed
8725 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8727 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8730 *) Properly check errno to prevent display of a directory index
8731 when server receives a long enough URL to confuse stat().
8734 *) Several security enhancements to suexec wrapper. It is _highly_
8735 recommended that previously installed versions of the wrapper
8736 be replaced with this version. [Randy Terbush, Jason Dour]
8738 - ~user execution now properly restricted to ~user's home
8739 directory and below.
8740 - execution restricted to UID/GID > 100
8741 - restrict passed environment to known variables
8742 - call setgid() before initgroups() (portability fix)
8743 - remove use of setenv() (portability fix)
8745 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8747 *) Add access control via environment variables. [Ben Laurie]
8749 *) Add rflush() function. [Alexei Kosut]
8751 *) remove duplicate pcalloc() call in new_connection().
8753 *) Fix incorrect comparison which could allow number of children =
8754 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8755 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8757 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8758 AIX PS/2, CONVEXOS. [Jim Jagielski]
8760 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8761 It's more portable. [Martin Kraemer]
8763 *) Replace references to make in Makefile.tmpl with $(MAKE).
8766 *) Add ProxyBlock directive w/IP address caching. Add IP address
8767 caching to NoCache directive as well. ProxyBlock works with all
8768 handlers; NoCache now also works with FTP for anonymous logins.
8769 Still more code cleanup. [Chuck Murcko]
8771 *) Add "header parse" API hook [Ben Laurie]
8773 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8775 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8777 *) Correctly allow access and auth directives in <Files> sections in
8778 server config files. [Alexei Kosut]
8780 *) Fix bug with ServerPath that could cause certain files to be not
8781 found by the server. [Alexei Kosut]
8783 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8784 double-quote from text and so that it properly checks for unsupported
8785 status codes using the new index_of_response interface. [Roy Fielding]
8787 *) Multiple fixes to the lingering_close code in order to avoid being
8788 interrupted by a stray timeout, to avoid lingering on a connection
8789 that has already been aborted or never really existed, to ensure that
8790 we stop lingering as soon as any error condition is received, and to
8791 prevent being stuck indefinitely if the read blocks. Also improves
8792 reporting of error conditions. [Marc Slemko and Roy Fielding]
8794 *) Fixed initialization of parameter structure for sigaction.
8795 [mgyger@itr.ch, Adrian Filipi-Martin]
8797 *) Fixed reinitializing the parameters before each call to accept and
8798 select, and removed potential for infinite loop in accept.
8799 [Roy Fielding, after useful PR from adrian@virginia.edu]
8801 *) Fixed condition where, if a child fails to fork, the scoreboard would
8802 continue to say SERVER_STARTING forever. Eventually, the main process
8803 would refuse to start new children because count_idle_servers() will
8804 count those SERVER_STARTING entries and will always report that there
8805 are enough idle servers. [Phillip Vandry]
8807 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8808 Avoided calling bflush() when the client is pipelining requests.
8809 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8811 *) Added description of "." mode in server-status [Jim Jagielski]
8813 Changes with Apache 1.2b4
8815 *) Fix possible race condition in accept_mutex_init() that
8816 could leave a small security hole open allowing files to be
8817 overwritten in cases where the server UID has write permissions.
8820 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8822 *) Fix portablity problem in util_script where ARG_MAX may not be
8823 defined for some systems.
8825 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8828 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8829 style magic #! token for better script portability. [Garey Smiley]
8831 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8832 execution for ~userdir CGI. [Jason Dour]
8834 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8836 *) Fix month off by one in suexec wrapper logging.
8838 Changes with Apache 1.2b3:
8840 *) Fix error in mod_cgi which could cause resources not to be properly
8841 freed, or worse. [Dean Gaudet]
8843 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8845 *) Add set_flag_slot() at the request of Dirk and others.
8848 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8850 *) Add changes to improve the error message given for invalid
8851 ServerName parameters. [Dirk vanGulik]
8853 *) Add "Authoritative" directive for Auth modules that don't
8854 currently have it. This gives admin control to assign authoritative
8855 control to an authentication scheme and allow "fall through" for
8856 those authentication modules that aren't "Authoritative" thereby
8857 allowing multiple authentication mechanisms to be chained.
8860 *) Remove requirement for ResourceConfig/AccessConfig if not using
8861 the three config file layout. [Randy Terbush]
8863 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8865 *) Changes to suexec wrapper to fix the following problems:
8866 1. symlinked homedirs will kill ~userdirs.
8867 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8868 3. CGI command lines paramters problems
8869 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8870 [Randy Terbush, Jason Dour]
8872 *) Change create_argv() to accept variable arguments. This fixes
8873 a problem where arguments were not getting passed to the CGI via
8874 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8876 *) Collapse multiple slashes in path URLs to properly apply
8877 handlers defined by <Location>. [Alexei Kosut]
8879 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8881 *) Improve the accuracy of request duration timings by setting
8882 r->request_time in read_request_line() instead of read_request().
8885 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8886 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8888 *) Add the ability to pass different Makefile.tmpl files to Configure
8889 using the -make flag. [Rob Hartill]
8891 *) Fix coredump triggered when sending a SIGHUP to the server caused
8892 by an assertion failure, in turn caused by an uninitialised field in a
8896 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8897 PATH_INFO from previous versions of Apache (in certain situations,
8898 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8899 [later removed in 1.2b11]
8901 *) Add rwrite() function to API to allow for sending strings of
8902 arbitrary length. [Doug MacEachern]
8904 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8906 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8907 NeXT. [Jim Jagielski]
8909 *) Removed recent modification to promote the status code on internal
8910 redirects, since the correct fix was to change the default log format
8911 in mod_log_config so that it outputs the original status. [Rob Hartill]
8913 Changes with Apache 1.2b2:
8915 *) Update set_signals() to use sigaction() for setting handlers.
8916 This appears to fix a re-entrant problem in the seg_fault()
8917 bus_error() handlers. [Randy Terbush]
8919 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8921 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8923 *) proxy_http.c bugfixes: [Chuck Murcko]
8924 1) fixes possible NULL pointer reference w/NoCache
8925 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8926 host would cache nothing if it was in the local domain,
8927 and the local domain was in the NoCache list)
8928 3) Adds Host: header when not available
8929 4) Some code cleanup and clarification
8931 *) mod_include.c bugfixes:
8932 1) Fixed an ommission that caused include variables to not
8933 be parsed in config errmsg directives [Howard Fear]
8934 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8935 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8936 4) Allow backslash-escaping to all quoted text
8937 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8938 5) Pass variable to command line if not set in XSSI's env
8941 *) Fix infinite loop when processing Content-language lines in
8942 type-map files. [Alexei Kosut]
8944 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8946 *) Fixed problem in set_[user|group] that prevented CGI execution
8947 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8949 *) Added PORTING information file. [Jim Jagielski]
8951 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8953 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8955 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8956 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8958 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8959 which caused problems of systems where socket s_addr is >32bits.
8961 *) Added comment to explain (r->chunked = 1) side-effect in
8962 http_protocol.c [Roy Fielding]
8964 *) Replaced use of index() in mod_expires.c with more appropriate
8965 and portable isdigit() test. [Ben Laurie]
8967 *) Updated Configure for ...
8968 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8969 *-dg-dgux* (bad pattern match)
8970 QNX (DEF_WANTHSREGEX=yes)
8971 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8974 and added some user diagnostic info. [Ben Laurie]
8976 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8977 for better portability. [Jim Jagielski]
8979 *) Updated helpers/GuessOS for ...
8980 SCO 5 (recognize minor releases)
8981 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8982 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8983 IRIX64 (-sgi-irix64)
8984 ULTRIX (-unknown-ultrix)
8985 SINIX (-whatever-sysv4)
8986 NCR Unix (-ncr-sysv4)
8987 and fixed something in helpers/PrintPath [Ben Laurie]
8989 Changes with Apache 1.2b1
8991 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8993 Changes with Apache 1.1.1
8995 *) Fixed bug where Cookie module would make two entries in the
8996 logfile for each access [Mark Cox]
8998 *) Fixed bug where Redirect in .htaccess files would cause memory
8999 leak. [Nathan Neulinger]
9001 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
9003 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
9005 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
9007 Changes with Apache 1.1.0
9009 *) Bring NeXT support up to date. [Takaaki Matsumoto]
9011 *) Bring QNX support up to date. [Ben Laurie]
9013 *) Make virtual hosts default to main server keepalive parameters.
9014 [Alexei Kosut, Ben Laurie]
9016 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
9018 *) Fix missing address family for connect, also remove unreachable statement
9019 in mod_proxy. [Ben Laurie]
9021 *) mod_env now turned on by default in Configuration.tmpl.
9023 *) Bugs which were fixed:
9024 a) yet more mod_proxy bugs [Ben Laurie]
9025 b) CGI works again with inetd [Alexei Kosut]
9026 c) Leading colons were stripped from passwords [osm@interguide.com]
9027 d) Another fix to multi-method Limit problem [jk@tools.de]
9029 Changes with Apache 1.1b4
9031 *) r->bytes_sent variable restored. [Robert Thau]
9033 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
9035 *) More possibly unsecure programs removed from the support directory.
9037 *) More mod_auth_msql authentication improvements.
9039 *) VirtualHosts based on Host: headers no longer conflict with the
9042 *) OS/2 compatibility enhancements. [Gary Smiley]
9044 *) POST now allowed to directory index CGI scripts.
9046 *) Actions now work with files of the default type.
9048 *) Bugs which were fixed:
9049 a) more mod_proxy bugs
9050 b) early termination of inetd requests
9051 c) compile warnings on several systems
9052 d) problems when scripts stop reading output early
9054 Changes with Apache 1.1b3
9056 *) Much of cgi-bin and all of cgi-src has been removed, due to
9057 various security holes found and that we could no longer support
9060 *) The "Set-Cookie" header is now special-cased to not merge multiple
9061 instances, since certain popular browsers can not handle multiple
9062 Set-Cookie instructions in a single header. [Paul Sutton]
9064 *) rprintf() added to buffer code, occurrences of sprintf removed.
9067 *) CONNECT method for proxy module, which means tunneling SSL should work.
9068 (No crypto needed) Also a NoCache config directive.
9070 *) Several API additions: pstrndup(), table_unset() and get_token()
9071 functions now available to modules.
9073 *) mod_imap fixups, in particular Location: headers are now complete
9076 *) New "info" module which reports on installed module set through a
9077 special URL, a la mod_status.
9079 *) "ServerPath" directive added - allows for graceful transition
9080 for Host:-header-based virtual hosts.
9082 *) Anonymous authentication module improvements.
9084 *) MSQL authentication module improvements.
9086 *) Status module design improved - output now table-based. [Ben Laurie]
9088 *) htdigest utility included for use with digest authentication
9091 *) mod_negotiation: Accept values with wildcards to be treated with
9092 less priority than those without wildcards at the same quality
9093 value. [Alexei Kosut]
9095 *) Bugs which were fixed:
9096 a) numerous mod_proxy bugs
9097 b) CGI early-termination bug [Ben Laurie]
9098 c) Keepalives not working with virtual hosts
9099 d) RefererIgnore problems
9100 e) closing fd's twice in mod_include (causing core dumps on
9101 Linux and elsewhere).
9103 Changes with Apache 1.1b2
9106 a) core dumps in mod_digest
9107 b) truncated hostnames/ip address in the logs
9108 c) relative URL's in mod_imap map files
9110 Changes with Apache 1.1b1
9112 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
9114 Changes with Apache 1.0.3
9116 *) Internal redirects which occur in mod_dir.c now preserve the
9117 query portion of a request (the bit after the question mark).
9120 *) Escape active characters '<', '>' and '&' in html output in
9121 directory listings, error messages and redirection links.
9124 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
9126 *) Fix for POSIX compliance in waiting for processes in alloc.c.
9129 *) setsockopt no longer takes a const declared argument [Martijn Koster]
9131 *) Reset timeout timer after each successful fwrite() to the network.
9132 This patch adds a reset_timeout() procedure that is called by
9133 send_fd() to reset the timeout ever time data is written to the net.
9136 *) timeout() signal handler now checks for SIGPIPE and reports
9137 lost connections in a more user friendly way. [Rob Hartill]
9139 *) Location of the "scoreboard" file which used to live in /tmp is
9140 now configurable (for OSes that can't use mmap) via ScoreBoardFile
9141 which works similar to PidFile (in httpd.conf) [Rob Hartill]
9143 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
9145 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
9146 which caused a SEGV with cookies enabled
9148 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
9151 *) Log the UNIX textual error returned by some system calls, in
9152 particular errors from accept() [David Robinson]
9154 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
9156 Changes with Apache 1.0.2
9158 *) patch to get Apache compiled on UnixWare 2.x, recommended as
9159 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
9161 *) Fix get_basic_auth_pw() to set the auth_type of the request.
9164 *) past changes to http_config.c to only use the
9165 setrlimit function on systems defining RLIMIT_NOFILE
9166 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
9167 for SUNOS and prototypes the needed functions.
9169 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
9172 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
9174 *) Merge multiple headers from CGI scripts instead of taking last
9175 one. [David Robinson]
9177 *) Add support for SCO 5. [Ben Laurie]
9179 Changes with Apache 1.0.1
9181 *) Silence mod_log_referer and mod_log_agent if not configured
9184 *) Recursive includes can occur if the client supplies PATH_INFO data
9185 and the server provider uses relative links; as file.html
9186 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
9188 *) The replacement for initgroups() did not call {set,end}grent(). This
9189 had two implications: if anything else used getgrent(), then
9190 initgroups() would fail, and it was consuming a file descriptor.
9193 *) On heavily loaded servers it was possible for the scoreboard to get
9194 out of sync with reality, as a result of a race condition.
9195 The observed symptoms are far more Apaches running than should
9196 be, and heavy system loads, generally followed by catastrophic
9197 system failure. [Ben Laurie]
9199 *) Fix typo in license. [David Robinson]
9201 Changes with Apache 1.0.0 23 Nov 1995
9203 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
9205 Changes with Apache 0.8.16 05 Nov 1995
9207 *) New man page for 'httpd' added to support directory [David Robinson]
9209 *) .htgroup files can have more than one line giving members for a
9210 given group (each must have the group name in front), for NCSA
9211 back-compatibility [Robert Thau]
9213 *) Mutual exclusion around accept() is on by default for SVR4 systems
9214 generally, since they generally can't handle multiple processes in
9215 accept() on the same socket. This should cure flaky behavior on
9216 a lot of those systems. [David Robinson]
9218 *) AddType, AddEncoding, and AddLanguage directives take multiple
9219 extensions on a single command line [David Robinson]
9221 *) UserDir can be disabled for a given virtual host by saying
9222 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9223 that this didn't work. [David Robinson]
9225 *) Compiles on QNX [Ben Laurie]
9227 *) Corrected parsing of ctime time format [David Robinson]
9229 *) httpd does a perror() before exiting if it can't log its pid
9230 to the PidFile, to make diagnosing the error a bit easier.
9233 *) <!--#include file="..."--> can no longer include files in the
9234 parent directory, for NCSA back-compatibility. [David Robinson]
9236 *) '~' is *not* escaped in URIs generated for directory listings
9239 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9241 *) Fixed bug involving handling URIs with escaped %-characters
9242 in redirects [David Robinson]
9244 Changes with Apache 0.8.15 14 Oct 1995
9246 *) Switched to new, simpler license
9248 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9250 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9252 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9254 *) Correctly handles internal redirects to files with names containing '%'
9257 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9259 *) Use geteuid() rather than getuid() to see if we have root privilege,
9260 so that server correctly resets privilege if run setuid root. [Andrew
9263 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9266 *) Fix relative URLs in imagemap files [Randy Terbush]
9268 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9271 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9272 entries all name the same one. [David Robinson]
9274 *) Fix directory listings with filenames containing unusual characters
9277 *) Better URI-escaping for generated URIs in directories with filenames
9278 containing unusual characters [Ben Laurie]
9280 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9282 *) Unblock alarms on error return from spawn_child() [David Robinson]
9284 *) Sample Config files have extra note for SCO users [Ben Laurie]
9286 *) Configuration has note for HP-UX users [Rob Hartill]
9288 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9290 *) Nuked bogus #define in httpd.h [David Robinson]
9292 *) Better test for whether a system has setrlimit() [David Robinson]
9294 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9296 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9299 Changes with Apache 0.8.14 19 Sep 1995
9301 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9303 *) AddDescription works (better) [Ben Laurie]
9305 *) Leaves an intelligible error diagnostic when it can't set group
9306 privileges on standalone startup [Andrew Wilson]
9308 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9309 that machine, which claims to be BSD but does not support RLIMIT.
9312 *) gcc -Wall no longer complains about an unused variable when util.c
9313 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9315 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9317 Changes with Apache 0.8.13 07 Sep 1995
9319 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9321 *) Have built-in imagemap code recognize & honor Point directive [James
9324 *) Generate cleaner directory listings in directories with a mix of
9325 long and short filenames [Rob Hartill]
9327 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9329 *) Properly default ServerName for virtual servers [Robert Thau]
9331 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9332 Paul Richards and a cast of thousands...]
9334 *) On self-identified BSD systems (we don't try to guess any more),
9335 allocate a few extra file descriptors per virtual host with setrlimit,
9336 if we can, to avoid running out. [Randy Terbush]
9338 *) Write 22-character lock file name into buffer with enough space
9339 on startup [Konstantin Olchanski]
9341 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9344 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9346 *) Suppress -Wall warning by initializing variable in negotiation code
9347 [Tobias Weingartner]
9349 Changes with Apache 0.8.12 31 Aug 1995
9351 *) Doesn't pause three seconds after including a CGI script which is
9352 too slow to die off (this is done by not even trying to kill off
9353 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9354 after the entire document has been processed). [Robert Thau]
9356 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9358 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9360 *) Allows .htaccess files to override <Directory> sections naming the
9361 same directory [David Robinson]
9363 *) Removed an efficiency hack in sub_req_lookup_uri which was
9364 causing certain extremely marginal cases (e.g., ScriptAlias of a
9365 *particular* index.html file) to fail. [David Robinson]
9367 *) Doesn't log an error when the requested URI requires
9368 authentication, but no auth header line was supplied by the
9369 client; this is a normal condition (the client doesn't no auth is
9370 needed here yet). [Robert Thau]
9372 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9374 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9376 *) RFC931 code no longer passes out name of prior clients on current
9377 requests if the current request came from a server that doesn't
9378 do RFC931. [David Robinson]
9380 *) Configuration script accepts "Module" lines with trailing whitespace.
9383 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9385 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9387 Changes with Apache 0.8.11 24 Aug 1995
9389 *) Wildcard <Directory> specifications work. [Robert Thau]
9391 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9393 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9394 the file being requested itself, in addition to the directories leading
9395 up to it. [Robert Thau]
9397 *) Logs access failures due to symlink checks or invalid client address
9398 in the error log [Roy Fielding, Robert Thau]
9400 *) Symlink checks deal correctly with systems where lstat of
9401 "/path/to/some/link/" follows the link. [Thau, Fielding]
9403 *) Doesn't reset DirectoryIndex to 'index.html' when
9404 other directory options are set in a .htaccess file. [Robert Thau]
9406 *) Clarified init code and nuked bogus warning in mod_access.c
9409 *) Corrected several directives in sample srm.conf
9410 --- includes corrections to directory indexing icon-related directives
9411 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9412 icons for encodings right, and turning on AddEncoding by default).
9415 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9418 *) INSTALL & README mention "contributed modules" directory [Brian
9421 *) Fixed English in the license language... "for for" --> "for".
9424 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9425 mod_alias.c, merging it almost completely with handling of Alias, and
9426 adding a 'notes' field to the request_rec which allows the CGI module
9427 to discover whether the Alias module has put this request through
9428 ScriptAlias (which it needs to know for back-compatibility, as the old
9429 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9432 Changes with Apache 0.8.10 18 Aug 1995
9434 *) AllowOverride applies to the named directory, and not just
9435 subdirectories. [David Robinson]
9437 *) Do locking for accept() exclusion (on systems that need it)
9438 using a special file created for the purpose in /usr/tmp, and
9439 not the error log; using the error log causes real problems
9440 if it's NFS-mounted; this is known to be the cause of a whole
9441 lot of "server hang" problems with Solaris. [David Robinson;
9442 thanks to Merten Schumann for help diagnosing the problem].
9444 Changes with Apache 0.8.9 12 Aug 1995
9446 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9448 *) Nested includes see environment variables of the including document,
9449 for NCSA bug-compatibility (some sites have standard footer includes
9450 which try to print out the last-modified date). [Eric Hagberg/Robert
9453 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9454 URI as a CGI script, even if it would have been treated as something
9455 else if requested directly, for NCSA back-compatibility. (Note that
9456 this means that people who know the name of the script can see the
9457 code just by asking for it). [Robert Thau]
9459 *) New version of dbmmanage script included in support directory as
9462 *) Check if scoreboard file couldn't be opened, and say so, rather
9463 then going insane [David Robinson]
9465 *) POST to CGI works on A/UX [Jim Jagielski]
9467 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9469 *) NCSA server push works properly --- the Arena bug compatibility
9470 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9471 if you still want the workaround). [Rob Hartill]
9473 *) If client didn't submit any Accept-encodings, ignore encodings in
9474 content negotiation. (NB this will all have to be reworked anyway
9475 for the new HTTP draft). [Florent Guillaume]
9477 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9479 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9481 *) Give Redirect priority over Alias, for NCSA bug compatibility
9484 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9485 paralleling earlier bug fix for CGI [David Robinson]
9487 *) If DBM auth is improperly configured, report a server error and don't
9490 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9491 it seems to work well enough without it (even in a 10 hits/sec
9492 workout), and the overhead for the locking under A/UX is
9493 alarmingly high (though it is very low on other systems).
9494 [Eric Hagberg, Jim Jagielski]
9496 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9498 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9499 Behlendorf/Eric Hagberg]
9501 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9503 *) Compiles clean on NEXT [Rob Hartill]
9505 *) Compiles clean on SGI [Robert Thau]
9507 Changes with Apache 0.8.8 08 Aug 1995
9509 *) SunOS library prototypes now never included unless explicitly
9510 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9511 people using GNU libc on SunOS are screwed by prototypes for the
9514 (Those who wish to compile clean with gcc -Wall on a standard
9515 SunOS setup need the prototypes, and may obtain them using
9516 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9517 with nonstandard libraries are presumably competent to make their
9520 *) Strips trailing '/' characters off both args to the Alias command,
9521 to make 'Alias /foo/ /bar/' work.
9523 Changes with Apache 0.8.7 03 Aug 1995
9525 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9526 [reported by David Robinson]
9528 *) Compiles clean on OSF/1 [David Robinson]
9530 *) Added some of the more recent significant changes (AddLanguage stuff,
9531 experimental LogFormat support) to CHANGES file in distribution root
9534 Changes with Apache 0.8.6 02 Aug 1995
9536 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9537 (If you actually wanted a conditional GET which bypassed the cache, you
9538 couldn't get it). [Reported by Roy Fielding]
9540 *) Properly terminate headers on '304 Not Modified' replies to conditional
9541 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9542 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9544 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9546 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9547 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9548 and older versions don't set the __SUNPRO_C preprocessor variable). On
9549 all other systems, these are never used anyway. [Reported by Mark Cox].
9551 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9553 Changes with Apache 0.8.5 01 Aug 1995
9555 *) Added last-minute configurable log experiment, as optional module
9557 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9558 properly. (One-line fix to http_protocol.c).
9560 *) Work around bogus behavior when reloading from Netscape.
9561 It's Netscape's bug --- for some reason they expect a request with
9562 If-modified-since: to not function as a conditional GET if it also
9563 comes with Pragma: no-cache, which is way out of line with the HTTP
9564 spec (according to Roy Fielding, the redactor).
9566 *) Added parameter to set maximum number of server processes.
9568 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9571 *) IdentityCheck bugfix [Chuck Murcko].
9573 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9575 *) More sample config file corrections; add extension to AddType for
9576 *.asis, move AddType generic description to its proper place, and
9577 fix miscellaneous typos. [ Alexei Kosut ]
9579 *) Deleted the *other* reference to the regents from the Berkeley
9580 legal disclaimer (everyplace).
9582 *) Nuked Shambhala name from src/README; had already cleaned it out
9585 Changes with Apache 0.8.4
9587 *) Changes to server-pool management parms --- renamed current
9588 StartServers to MinSpareServers, created separate StartServers
9589 parameter which means what it says, and renamed MaxServers to
9590 MaxSpareServers (though the old name still works, for NCSA 1.4
9591 back-compatibility). The old names were generally regarded as
9592 too confusing. Also altered "docs" in sample config files.
9594 *) More improvements to default config files ---
9595 sample directives (commented out) for XBitHack, BindAddress,
9596 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9597 defaults, AddTypes for send-as-is and imagemap magic types, and
9598 improvements to samples for DirectoryIndex [Alexei Kosut]
9600 *) Yet more improvements to default config files --- changes to
9601 Alexei's sample AddLanguage directives, and sample LanguagePriority
9602 [ Florent Guillaume ]
9604 *) Set config file locations properly if not set in httpd.conf
9607 *) Don't escape URIs in internal redirects multiple times; don't
9608 do that when translating PATH_INFO to PATH_TRANSLATED either.
9611 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9613 Changes with Apache 0.8.3
9615 *) Edited distribution README to *briefly* summarize installation
9616 procedures, and give a pointer to the INSTALL file in the src/
9619 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9620 recent NCSA distributions.
9622 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9623 exist for the same directory, use both and don't segfault. [Reported
9626 *) Proper makefile dependencies [David Robinson]
9628 *) Note (re)starts in error log --- reported by Rob Hartill.
9630 *) Only call no2slash() after get_path_info() has been done, to
9631 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9632 reported by Andrew Wilson, though this one is probably a real bug]
9634 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9635 dump core when Referer is not supplied. [Randy Terbush]
9637 *) Lightly edited sample config files to refer people to our documentation
9638 instead of NCSA's, and to list Rob McCool as *original* author (also
9639 deleted his old, and no doubt non-functional email address). Would be
9640 nice to have examples of new features...
9642 Changes with Apache 0.8.2 19 Jul 1995
9644 *) Added AddLanuage code [Florent Guillaume]
9646 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9648 *) All sorts of problems when MultiViews finds a directory. It would
9649 be nice if mod_dir.c was robust enough to handle that, but for now,
9650 just punt. [reported by Brian Behlendorf]
9652 *) Wait for all children on restart, to make sure that the old socket
9653 is gone and we can reopen it. [reported by Randy Terbush]
9655 *) Imagemap module is enabled in default Configuration
9657 *) RefererLog and UserAgentLog modules properly default the logfile
9660 *) Mark Cox's mod_cookies added to the distribution as an optional
9661 module (commented out in the default Configuration, and noted as
9662 an experiment, along with mod_dld). [Mark Cox]
9664 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9666 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9668 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9670 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9673 Changes with Apache 0.8.1
9675 *) New imagemap module [Randy Terbush]
9677 *) Replacement referer log module with NCSA-compatible RefererIgnore
9678 [Matthew Gray again]
9680 *) Don't mung directory listings with very long filenames.
9683 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9685 *) New config script. See INSTALL for info. [Robert Thau]
9687 *) Scoreboard mechanism for regulating the number of extant server
9688 processes. MaxServers and StartServers defaults are the same as
9689 for NCSA, but the meanings are slightly different. (Actually,
9690 I should probably lower the MaxServers default to 10).
9692 Before asking for a new connection, each server process checks
9693 the number of other servers which are also waiting for a
9694 connection. If there are more than MaxServers, it quietly dies
9695 off. Conversely, every second, the root, or caretaker, process
9696 looks to see how many servers are waiting for a new connection;
9697 if there are fewer than StartServers, it starts a new one. This
9698 does not depend on the number of server processes already extant.
9699 The accounting is arranged through a "scoreboard" file, named
9700 /tmp/htstatus.*, on which each process has an independent file
9701 descriptor (they need to seek without interference).
9703 The end effect is that MaxServers is the maximum number of
9704 servers on an *inactive* server machine, but more will be forked
9705 off to handle unusually heavy loads (or unusually slow clients);
9706 these will die off when they are no longer needed --- without
9707 reverting to the overhead of full forking operation. There is a
9708 hard maximum of 150 server processes compiled in, largely to
9709 avoid forking out of control and dragging the machine down.
9710 (This is arguably too high).
9712 In my server endurance tests, this mechanism did not appear to
9713 impose any significant overhead, even after I forced it to put the
9714 scoreboard file on a normal filesystem (which might have more
9715 overhead than tmpfs). [Robert Thau]
9717 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9720 *) Read .htaccess files even in directory with <Directory> section.
9721 (Former incompatibility noted on mailing list, now fixed). [Robert
9724 *) "HEAD /" gives the client a "Bad Request" error message, rather
9725 than trying to send no body *and* no headers. [Cliff Skolnick].
9727 *) Don't produce double error reports for some very obscure cases
9728 mainly involving auth configuration (the "all modules decline to
9729 handle" case which is a sure sign of a server bug in most cases,
9730 but also happens when authentication is badly misconfigured).
9733 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9734 it's *for*, and this sort of thing really shouldn't be cluttering
9735 up the Makefile). [Robert Thau]
9737 *) Incidental code cleanups in http_main.c --- stop dragging
9738 sa_client around; just declare it where used. [Robert Thau]
9740 *) Another acc-related fix. (It doesn't like const char
9741 in some places...). [Mark Cox]
9743 Changes with Shambhala 0.6.1 13 Jul 1995
9745 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9746 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9748 *) Compiles clean with acc on SunOS [Paul Sutton]
9750 *) Reordered modules in modules.c so that Redirect takes priority
9751 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9752 believe it or not, he has an actual site with a ScriptAlias and
9753 a Redirect declared for the *exact same directory*. Even *my*
9754 compatibility fetish wouldn't motivate me to fix this if the fix
9755 required any effort, but it doesn't, so what the hey.
9757 *) Fixed to properly default several server_rec fields for virtual
9758 servers from the corresponding fields in the main server_rec.
9759 [Cliff Skolnick --- 'port' was a particular irritant].
9761 *) No longer kills off nph- child processes before they are
9762 finished sending output. [Matthew Gray]
9764 Changes with Shambhala 0.6.0 10 Jul 1995
9766 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9767 the connection to the client in an "aborted" state, but otherwise
9768 allow whatever handlers are running to clean up. hard_timeout()s
9769 abort the request in progress completely; anything not tied to some
9770 resource pool cleanup will leak. They're still around because I
9771 haven't yet come up with a more elegant way of handling
9772 timeouts when talking to something that isn't the client. The
9773 default_handler and the dir_handler now use soft timeouts, largely
9774 so I can test the feature. [Robert Thau]
9776 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9777 the case of log handlers dying prematurely is probably handled VERY
9778 gracelessly at this point, and if the logger stops reading input,
9779 the server will hang. (It is known to correctly restart the
9780 logging process on server restart; this is (should be!) going through
9781 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9782 script). [Robert Thau]
9784 *) asis files supported (new module). [Robert Thau]
9786 *) IdentityCheck code is compiled in, but has not been tested. (I
9787 don't know anyone who runs identd). [Robert Thau]
9789 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9790 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9792 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9794 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9795 as timeouts are not in scope. [Robert Thau]
9797 *) quoted-string args in config files now handled correctly (doesn't drop
9798 the last character). [Robert Thau; reported by Randy Terbush]
9800 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9801 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9803 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9804 default default type); the former default default behavior when all
9805 type-checkers defaulted had been a core dump. [Paul Sutton]
9807 *) Copy filenames out of the struct dirent when indexing
9808 directories. (On Linux, readdir() returns a pointer to the same
9809 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9811 Changes with Shambhala 0.5.3 [not released]
9813 *) Default response handler notes "file not found" in the error log,
9814 if the file was not found. [Cliff Skolnick].
9816 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9817 code no longer sets up bogus PATH_INFO which fakes out the directory
9818 handler). [Cliff Skolnick]
9820 Changes with Shambhala 0.5.2 06 Jul 1995
9822 *) Changes to http_main.c --- root server no longer plays silly
9823 games with SIGCHLD, and so now detects and replaces dying
9824 children. Child processes just die on SIGTERM, without taking
9825 the whole process group with them. Potential problem --- if any
9826 child process refuses to die, we hang in restart.
9827 MaxRequestsPerChild may still not work, but it certainly works
9828 better than it did before this! [Robert Thau]
9830 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9831 work (or work better, at least); over-long description lines
9832 properly terminated. [Mark Cox]
9834 *) http_request.c now calls unescape_url() more places where it
9835 should [Paul Sutton].
9837 *) More directory handling bugs (reported by Cox)
9838 Parent Directory link is now set correctly. [Robert Thau]
9840 Changes with Shambhala 0.5.1 04 Jul 1995
9842 *) Generalized cleanup interface in alloc.c --- any function can be
9843 registered with alloc.c as a cleanup for a resource pool;
9844 tracking of files and file descriptors has been reimplemented in
9845 terms of this interface, so I can give it some sort of a test.
9848 *) More changes in alloc.c --- new cleanup_for_exec() function,
9849 which tracks down and closes all file descriptors which have been
9850 registered with the alloc.c machinery before the server exec()s a
9851 child process for CGI or <!--#exec-->. CGI children now get
9852 started with exactly three file descriptors open. Hopefully,
9853 this cures the problem Rob H. was having with overly persistent
9854 CGI connections. [Robert Thau]
9856 *) Mutual exclusion around the accept() in child_main() --- this is
9857 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9858 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9859 This uses fcntl(F_SETLK,...) on the error log descriptor because
9860 flock() on that descriptor won't work on systems which have BSD
9861 flock() semantics, including (I think) Linux 1.3 and Solaris.
9863 This does work on SunOS (when the server is idle, only one
9864 process in the pool is waiting on accept()); it *ought* to work
9865 on the other systems. [Robert Thau]
9867 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9869 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9871 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9873 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9874 be unnecessary if I go to the revised timeout-handling scheme).
9877 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9878 string) even if none came in with the request. [Robert Thau]
9880 *) CHANGES file added to distribution ;-).
9882 Changes with Shambhala 0.4.5
9884 *) mod_dld --- early dynamic loading support [rst]
9885 *) Add wildcard content handlers for XBITHACK; default_hander now
9886 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9887 *) XBITHACK supported as a wildcard content-handler, and
9888 configurable at run-time (not just at compile time, as in the
9889 "patchy server" releases) [rst]
9891 Changes with Shambhala 0.4.4 30 Jun 1995
9893 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9894 *) Handle Addtype x/y .z [rst, reported by Cox]
9896 Changes with Shambhala 0.4.3
9898 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9899 synonymous [rst, terbush]
9901 Changes with Shambhala 0.4.1 28 Jun 1995
9903 *) First-cut virtual host implementation; some refit in the config
9904 reading code, and log management, was necessary to support this [rst]
9905 *) Sub-pool machinery, originally added to avoid excessive storage
9906 allocation on listings of large directories (which turned out to
9907 be the problem that the 0.3 storage accounting was added to
9908 find). Subrequests and mod_dir changed to use subpools. [rst]
9909 *) More memory debugging --- free list consistency checks. [rst]
9910 *) Added err_headers to request_rec, with support elsewhere [rst]
9911 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9913 Changes with Shambhala 0.3 19 Jun 1995
9915 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9916 *) Don't compile in mod_ai_backcompat by default
9917 *) Switch name of server from Apache to Shambhala in Makefile
9918 *) Add some accounting routines to track memory usage in the pools,
9921 Changes with Shambhala 0.2
9923 *) Set DOCUMENT_ROOT CGI variable
9924 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9925 *) Add critical section protection to handling of cleanup structures
9927 *) Significant code reorg within the server core to group related
9928 functions together [rst]
9929 *) Correctly handle clients that hang up before sending any request
9931 *) Replace dying child processes. [rst]
9933 Changes with Shambhala 0.1 12 Jun 1995
9935 Major rewrite of the pre-existing "patchy server" codebase, by
9936 Robert Thau (rst). Significant portions of the server code, such
9937 as configuration-file handling and HTTP authentication support,
9938 were ripped out and rewritten from scratch. Code that was not
9939 completely rewritten was significantly altered.
9941 Major changes with this release include:
9943 *) Introduction of the module API; in request handling, the central
9944 machinery just dispatches to various modules, which actually do
9945 most of the work. Configuration handling is similar --- modules
9946 declare their own commands, and the central machinery just
9949 API features from shambhala/0.1 were substantially unchanged in
9950 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9951 release, such as wildcard handlers and subpools, were added in
9952 subsequent Shambhala releases, and were also generally rst's
9955 *) This release included the following modules:
9957 mod_access (access control --- allow and deny directives),
9958 mod_alias (Alias and Redirect commands),
9959 mod_auth (straight HTTP authentication, based on flat-files)
9960 mod_auth_dbm (same, with dbm files)
9961 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9962 mod_common_log (CLF access logs; later renamed mod_log_common)
9963 mod_dir (directory indexing)
9964 mod_include (server-side includes)
9965 mod_mime (AddType directives)
9966 mod_negotiation (content negotiation)
9967 mod_userdir (support for users' public_html directories)
9969 It also included a mod_ai_backcompat, which was a private hack
9970 for back-compatibility with rst's own AI-lab servers.
9972 All of these modules were substantially complete, and functional
9973 or nearly so (a few, which implemented features not in use at
9974 Thau's site, required patches of a few lines).
9976 *) sub-request machinery, to allow modules to determine how other
9977 modules would assign MIME types to a given file, or optionally
9978 serve its content (this is heavily used by mod_dir, mod_include
9979 and mod_negotiation).
9981 *) Resource pool system for keeping track of memory allocated and
9982 files opened in service of a particular request. Much of the
9983 code in the modules (when they weren't rewrites) was adjusted to
9984 replace a pervasive convention of using fixed-size buffers on
9985 the stack with an equally pervasive convention of using memory
9986 allocated with palloc().
9988 *) Reorganization of data structures associated with a given
9989 request to eliminate use of global variables and the troublesome
9990 unmunge_name function (used in NCSA and early Apache releases to
9991 attempt to determine the URI which mapped to a given filename
9992 --- a difficult proposition, given that it is easy to produce
9993 setups in which multiple URIs map to the same file).
9995 *) Source files renamed and rearranged
9997 *) Very simple pre-forking behavior --- parent process forked off a
9998 fixed number of children, and then just waited for SIGHUP.
10000 *) Other more minor changes too numerous to list.
10002 This release included modified versions of a lot of code from the
10003 Apache 0.6.4 public release, plus an early pre-forking patch
10004 codeveloped by Robert Thau and Rob Hartill.
10006 Changes with Apache 0.7.3 20 Jun 1995
10008 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
10009 were incorporated by Rob Hartill on the main branch while Robert Thau
10010 worked on the Shambhala rewrite above. Most were merged into the
10011 Shambala architecture after Apache 0.8.0.
10013 Changes with Apache 0.6.4 13 May 1995
10015 *) Patches by Rob Hartill, Cliff Skolnick, Randy Terbush, Robert Thau,
10018 Changes with Apache 0.5.1 10 Apr 1995
10020 Changes with Apache 0.4 02 Apr 1995
10022 *) Patches by Brian Behlendorf, Andrew Wilson, Robert Thau,
10025 Changes with Apache 0.3 24 Mar 1995
10027 *) Patches by Robert Thau, David Robinson, Rob Hartill, and
10030 Changes with Apache 0.2 18 Mar 1995
10032 *) Based on NCSA httpd 1.3 by Rob McCool and patches by CERT,
10033 Roy Fielding, Robert Thau, Nicolas Pioch, David Robinson,
10034 Brian Behlendorf, Rob Hartill, and Cliff Skolnick.
