1 Changes with Apache 2.0.22
3 *) Apache/Win32 now fills in the service description with Apache's
4 server version string, including loaded and advertised modules.
7 *) Improved support for the Win32 build, to recover gracefully from
8 missing apr or apr-util directories or the awk interpreter,
9 create the proper cgi-bin examples, including a test-cgi.bat, and
10 fix the perl shebang line for printenv.pl, when installing from
11 the build environment. [William Rowe]
13 *) Fix a segfault in threaded.c caused by passing uninitialized
14 apr_thread_t * to apr_thread_join(). [Jeff Trawick]
16 *) Use new APR number conversion functions to reduce CPU consumption
17 when setting the content length, and in mod_log_config.
20 *) Fix problem reported by Taketo Kabe <kabe@sra-tohoku.co.jp>
21 where HEAD response headers were being repeated twice for
22 files greater than 32K bytes (4*AP_MIN_BYTES_TO_WRITE). This
23 problem in the http_header filter was exposed by the recent rewrite
24 of the content_length filter. [Taketo Kabe, Bill Stoddard]
26 *) Fix seg faults in mod_status with ExtendedStatus enabled, after
27 restarts. A garbage pointer to a vhost's server_rec from the
28 previous generation was being left around under certain
29 conditions. [Greg Ames]
31 *) Fix a cosmetic problem with mod_include. Non-existant SSI vars
32 used to appear as '(none', without the closing paren.
33 [Günter Knauf <eflash@gmx.net>]
35 *) Improve the exports generating awk script. In the past, we had
36 work around problems in the awk script by avoiding some #if and
37 #ifdefs. This has bitten us many times in generating the exports.c
38 file. This improvement allows corrects the header file parsing.
39 [Sander Striker <striker@apache.org>]
41 Changes with Apache 2.0.21
43 *) Resolve the Win32 htpasswd bug, where a file that existed would be
44 overwritten, regardless of the -c flag.
45 [William Rowe, Mladen Turk <mladen.turk@mail.inet.hr>]
47 *) Introduce connection sub-pools into ab. Truncating the lifetime
48 of these allocations means that ab no longer perpetually grows
49 its working set, running out of memory on large request attempts.
52 *) Make scoreboard creation a hook. This allows management
53 modules to have access to the scoreboard at the time that it is
54 created, and at every restart request.
55 [Cody Sherr <csherr@covalent.net>]
57 *) Changed AP_MPMQ_MAX_DAEMONS to refer to MaxClients and
58 added an AP_MPMQ_MAX_DAEMON_USED to refer to the highest
59 daemon index actually used in the scoreboard. I also
60 updated the pertinent calls. [Paul J. Reder]
62 *) Win32: Prevent listening sockets from being inherited by
63 the Apache child process, CGI scripts, rotatelog process
64 etc. If the Apache child process segfaults, any processes
65 that the child started are not reaped. Prior to this fix,
66 these processes inherited the listening sockets which sometimes
67 prevented the restarted Apache child process from accepting
68 connections (ie, the server would hang).
71 *) Provide vhost and request strings when ExtendedStatus is on.
74 *) Fix some issues with the pod and prefork: check the pod *after*
75 processing a connection so that a server processing a time-
76 consuming request bails out as soon as practical; when the
77 parent process wakes up a server process via connect(), use an
78 APR timeout on the connect() so that we don't hang for a long
79 time if there aren't server processes around to do accept().
80 [Jeff Trawick, Greg Ames]
82 *) Performance improvement to mod_mime.c. find_ct() in mod_mime,
83 spends a lot of time in apr_table_get calls. Using the default
84 httpd.conf, the tables for languages and charsets are somewhat
85 large, so the time spent scanning them on each request is
86 significant. Replacing the tables with hash tables provides
87 a nice speedup. [Brian Pane <bpane@pacbell.net>]
89 *) Add two functions to allow modules to access random parts of the
90 scoreboard. This allows modules compiled for one MPM to access the
91 scoreboard, even if it the server was compiled for another MPM.
92 [Harrie Hazewinkel <harrie@covalent.net>]
94 Changes with Apache 2.0.20
96 *) Fix problem in content-length filter where the filter would
97 buffer all the output from a CGI before sending any bytes
98 down the filter stack to the network. This problem would cause
99 significant memory consumption if the CGIs generated
100 lots of bytes. [Bill Stoddard]
102 *) Get non-blocking CGI pipe reads working with the bucket brigades.
105 *) Fix seg fault on Windows when serving files cached with mod_file_cache.
108 *) Fix a bug in the threaded MPM that would cause it to kill off all
109 workers immediately after starting if the number of workers started
110 was above a certain threshold. [Ryan Bloom, Bill Stoddard]
112 Changes with Apache 2.0.19
114 *) Fix problem with threaded MPM. The problem was that if each child
115 process was busy serving a single long-lived request and the server
116 was sent a graceful restart signal, the server would stop serving
117 requests. This would happen because each child process would wait to
118 die until the last thread was done, and the parent wouldn't spawn any
119 new children until a process died. Now, the parent looks at the fact
120 that the children are dying gracefully, and starts new children.
121 Those new children only start enough threads to compliment the number
122 of threads in the other child process that shares the same spot in
123 the scoreboard. In this way, we make sure to never go over
124 MaxClients. [Ryan Bloom]
126 *) modified mod_negotiation and mod_autoindex to speed up by almost a
127 factor of two on apr_dir_read()-enhanced platforms, such as Win32
128 and OS2, by calling ap_sub_request_lookup_dirent() with the results
129 already provided by apr_dir_read(). [William Rowe]
131 *) mod_file_cache is now more robust to filtering and serves requests
132 slightly more efficiently. [Cliff Woolley]
134 *) Fix problem handling FLUSH bucket in the chunked encoding filter.
135 Module was calling ap_rwrite() followed by ap_rflush() but the
136 served content was not being displayed in the browser. Inspection
137 of the output stream revealed that the first data chunk was
138 missing the trailing CRLF required by the RFC. [Bill Stoddard]
140 *) apxs no longer generates ap_send_http_header() in the example handler
142 *) Fix an ab problem which could cause a divide-by-zero exception
143 with certain invocations (e.g., ab -k -c 6 -n 100 localhost/).
144 [Ian Holsman <ianh@cnet.com>]
146 *) Solve case-insensitive platforms' confusion about negotiated
147 filenames, allowing files of differnt case to match in choosing
148 the document to serve. [William Rowe]
150 *) Fix brokenness when ThreadsPerChild is higher than the built-in
151 limit. We left ap_threads_per_child at the higher value which
152 led to segfaults when doing certain scoreboard operations.
155 *) Fix seg faults and/or missing output from mod_include. The
156 default_handler was using the subrequest pool for files and
157 MMAPs, even though the associated APR structures typically
158 live longer than the subrequest. [Greg Ames]
160 *) Extend mod_setenvif to support specifying regular expressions
161 on the SetEnvIf (and SetEnvIfNoCase) directive attribute field.
162 Example: SetEnvIf ^TS* [a-z].* HAVE_TS
163 will cause HAVE_TS to be set if any of the request headers begins
164 with "TS" and has a value that begins with any character in the
165 set [a-z]. [Bill Stoddard]
167 *) httpd children now re-bind themselves to a random CPU on
168 multiprocessor systems on AIX via bindprocessor() in 2.0.
169 [Victor J. Orlikowski]
171 *) Fix htdigest. It would go into a loop in getline when adding
172 a second user. [Bill Stoddard]
174 *) Win32 platforms now fully support mod_userdir options. [Will Rowe]
176 *) Automatically generate httpd.exp for AIX.
177 DSOs now work again on AIX in 2.0
178 [Victor J. Orlikowski]
180 *) Add a new request hook, error_log. This phase allows modules
181 to act on the error log string _after_ it has been written
182 to the error log. The goal for this hook is to allow monitoring
183 modules to send the error string to the monitoring agent.
186 *) Modify mod_echo to make it use filters for input and output.
187 [Ryan Morgan <rmorgan@covalent.net>]
189 *) Extend mod_headers to support conditional driven Header
190 add, append and set. Use SetEnvIf to set an envar and conditionally
191 add/append/set headers based on this envar thusly:
193 SetEnvIf TSMyHeader value HAVE_TSMyHeader
194 Header add MyHeader "%t %D" env=HAVE_TSMyHeader
196 If the request contains header "TSMyHeader: value" then header
197 MyHeader: "t=xxxxxxxxxx D=yyyy" will be sent on the response.
200 *) Extend mod_headers to support using format specifiers on Header
201 add, append and set header values. Two format specifiers are supported:
203 %t - reports, in UTC microseconds since the epoch, when the
204 request was received.
206 %D - reports the time, in microseconds, between when the request was
207 received and the response sent.
210 Header add MyHeader "This request served in %D microseconds. %t"
212 results in a header being added to the response that looks like this:
214 MyHeader: This request served in D=5438 microseconds. t=991424704447256
218 *) Fix reset_filter(). We need to be careful how we remove filters.
219 If we set r->output_filters to NULL, we also have to reset the
220 connection's filters. [John Sterling]
222 *) Optimise reset_filter() in http_protocol.c. [Greg Stein]
224 *) Add a check to ap_die() to make sure the filter stack is sane and
225 contains the correct basic filters when an error occurs. This fixes
226 a problem where headers are not being sent on error. [John Sterling]
228 *) New Header directive 'echo' option. "Header echo regex" will
229 cause any headers received on the request that match regex to be
230 echoed to (included in) the response headers.
233 *) include/ap_compat.h tested and set APR_COMPAT_H instead of AP_COMPAT_H.
234 This prevented the inclusion of apr_compat.h. PR #7773
235 [Oleg Broytmann <phd@phd.pp.ru>]
237 *) Moved util_uri to the apr-util library. This required a bunch of
238 apr_name changes for the uri utility functions. [Justin Erenkrantz]
240 *) Move the addition of default AP_HTTP_HTTP_HEADER filters to the
241 insert_filter phase so that other filters are not bypassed by default.
244 *) Reimplement mod_headers as an output filter. mod_headers can now
245 add custom headers to inbound requests using the RequestHeader directive
246 and to responses using the same old Header directive. [Graham Leggett]
248 Changes with Apache 2.0.18
250 *) Fix command-line processing so that if a bad argument is specified
251 Apache will exit. [Jeff Trawick]
253 *) Change the make targets and rules to be consistent in all of the
254 Apache-owned source trees. [Roy Fielding]
256 *) Fix processing of the TRACE method. Previously we passed bogus
257 parms to form_header_field() and it overlaid some vhost structures,
258 resulting in a segfault in check_hostalias().
259 [Greg Ames, Jeff Trawick]
261 *) Win32: Add support for reliable piped logs. If the logging process
262 goes down, Apache will automatically restart it. This function has
263 been part of Apache on Unix/Linux/BSD since the early v1.3 releases.
266 *) Do not start piped log processes during the config file
267 preflight. This change also circumvents a problem on
268 Windows where the rotatelog processes created during preflight
269 was not getting cleaned up properly.
272 *) add "Request Phase Participation" info to mod_info
275 *) Make first phase changes to the scoreboard data structures in
276 preparation for the rewriting of the scoreboard per my posted
277 design notes. [Paul J. Reder]
279 *) Fix httpd's definition of LTFLAGS to be consistent with that of apr
280 and apr-util, allow it to be overridden by the configure command-line
281 (default="--silent") and introduce LT_LDFLAGS to replace what we were
282 formerly abusing as LTFLAGS. [Roy Fielding]
284 *) Clean up the reporting of incorrect closing container tags.
285 [Barrie Slaymaker <barries@slaysys.com>]
287 *) Simplify the configure process by moving all libtool stuff to APR
288 and moving hints.m4 inline. [Roy Fielding]
290 *) Add the AP_DECLARE()/AP_CORE_DECLARE macros on the return types
291 of functions used by mod_proxy for export in the DLL
292 [Ian Holsman <IanH@cnet.com>]
294 *) Prevent a hang when a cgi handled by mod_cgid tries to read a
295 request body from its stdin but no reqest body is being written to
296 the cgi. [Jeff Trawick]
298 *) mod_log_config: %c connection status incorrectly logged
299 as "-" (non-keepalive) when MaxKeepAliveRequests is set to 0.
302 *) Get mod_cern_meta working under Windows
305 *) Create Files, and thus MMAPs, out of the request pool, not the
306 connection pool. This solves a small resource leak that had us
307 not closing files until a connection was closed. In order to do
308 this, at the end of the core_output_filter, we loop through the
309 brigade and convert any data we have into a single HEAP bucket
310 that we know will survive clearing the request_rec.
311 [Ryan Bloom, Justin Erenkrantz <jerenkrantz@ebuilt.com>,
314 *) Completely revamp configure so that it preserves the standard make
315 variables CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS and LIBS by moving
316 the configure additions to EXTRA_* variables. Also, allow the user
317 to specify NOTEST_* values for all of the above, which eliminates the
318 need for THREAD_CPPFLAGS, THREAD_CFLAGS, and OPTIM. Fix the setting
319 of INCLUDES and EXTRA_INCLUDES. Check flags as they are added to
320 avoid pointless duplications. Fix the order in which flags are given
321 on the compile and link lines. Remove obsolete macros APR_DOEXTRA,
322 AC_ADD_LIBRARY, AC_CHECK_DEFINE, APACHE_PASSTHRU, and APACHE_ONCE.
323 Added APR_SAVE_THE_ENVIRONMENT and APR_RESTORE_THE_ENVIRONMENT macros.
324 Renamed AC_TYPE_RLIM_T macro to APACHE_TYPE_RLIM_T. [Roy Fielding]
326 *) Get mod_tls to compile/work better on Windows. PR #7612
327 [Bernhard Schrenk <b.schrenk@improx.com>]
329 *) Fix shutdown/restart hangs in the threaded MPM.
330 [Jeff Trawick, Greg Ames, Ryan Bloom]
332 *) Removed the keptalive boolean from conn_rec because it is now only
333 used by a single routine and can be replaced by a local variable.
334 [Greg Stein, Ryan Bloom, Roy Fielding]
336 *) Patch prefork to put enough of the signal processing back in so that
337 signals are all handled properly now. The previous patch fixed the
338 deadlock race condition, but broke the user directed signal handling.
339 This fixes it to work the way it did before my previous prefork patch
340 (primarily, SIGTERM is now working).
342 *) Change how input filters decide how much data is returned to the
343 higher filter. We used to use a field in the conn_rec, with this
344 change, we use an argument to ap_get_brigade to determine how much
345 data is retrieved. [Ryan Bloom]
347 *) Fix seg fault at start-up introduced by Ryan's change to enable
348 modules to specify their own logging tags. mod_log_config
349 registers an optional function, ap_register_log_handler().
350 ap_register_log_handler() was being called by http_core before
351 the directive hash table was created. This patch creates the
352 directive hash table before ap_register_log_handler() is
353 registered as an optional function.
354 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
356 *) Add ap_set_int_slot() function
357 [John K. Sterling <sterling@covalent.net>]
359 *) Under certain circumstances, Apache did not supply the
360 right response headers when requiring authentication.
361 [Gertjan van Wingerde <Gertjan.van.Wingerde@cmg.nl>] PR#7114
362 (This is a port of the change that went into Apache 1.3.19.)
364 *) Allow modules to specify their own logging tags. This basically
365 allows a module to tell mod_log_config that when %x is encountered
366 a specific function should be called. Currently, x can be any single
367 character. It may be more useful to make this a string at some point.
370 Changes with Apache 2.0.17
372 *) If a higher-level filter handles the the byterange aspects of a
373 request, then the byterange filter should not try to redo the
374 work. The most common case of this happening, is a byterange
375 request going through the proxy, and the origin server handles
376 the byterange request. The proxy should ignore it.
377 [Graham Leggett <minfrin@sharp.fm>]
379 *) Changed the threaded mpm to have child_main join to each of the
380 worker threads to make sure the kids are all gone before child_main
381 exits after a signal (cleanup from perform_idle_server_maintenance).
382 This is an extension of Ryans recent commit to make the child_main
385 *) Add more options to the ap_mpm_query function. This also allows MPMs to
386 report if their threads are dynamic or static. Finally, this also
387 implements a new API, ap_show_mpm, which returns the MPM that was
388 required into the core. [Harrie Hazewinkel <harrie@covalent.net>]
390 *) Do not install the binaries from the support directory twice.
391 [jun-ichiro hagino <itojun@iijlab.net>]
393 *) The ap_f* functions should flush data to the filter that is passed
394 in, not the the filter after the one passed in.
395 [Ryan Morgan <rmorgan@covalent.net>]
397 *) Make ab work again by changing its native types to apr types and formats.
398 [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
400 *) Move the byterange filter and all of the supporting functions back
401 to the HTTP module. The byterange filter turned out to be very
402 HTTP specific, and it belongs in the HTTP module. [Greg Stein]
404 *) Make clean, distclean, and extraclean consistently according to the
405 Gnu makefile guidelines. [Justin Erenkrantz <jerenkrantz@ebuilt.com>]
407 *) Fix errors in the renaming of the apr_threadattr_detach_xxx functions.
408 This may have been causing problems stopping processes in the threaded
411 *) Fix content-length in mod_negotiation to a long int representation.
414 *) Remove BindAddress from the default config file.
415 [giles@nemeton.com.au]
417 *) Allow module authors to add a module to their Apache build using
418 --with-module, without re-running buildconf. The syntax is:
419 --with-module=module_type:/path/to/module.c
420 The configure script will copy the module.c file to
421 modules/module_type, and it will be added to the relevant Makefiles.
422 currently, this only works for static modules. [Ryan Bloom]
424 *) Changes required to make prefork clean up idle children properly.
425 There was a window during which a starting worker deadlocks when
426 an idle cleanup arrives before it completes init. Apache then keeps
427 trying to cleanup the same deadlocked worker forever (until higher
428 pids come along, but it still will never reduce below the deadlocked
429 pid). Thus the number of children would not reduce to the correct
430 idle level. [Paul J. Reder]
432 Changes with Apache 2.0.16
434 *) Change the default installation directory to /usr/local/apache2,
435 as now defined by the "Apache" layout in config.layout. [Marc Slemko]
437 *) OS/2: Added support for building loadable modules as OS/2 DLLs.
440 *) Get MaxRequestsPerChild working with the Windows MPM.
443 *) Make generic hooks to work, with mod_generic_hook_import/export
444 experimental modules. [Ben Laurie, Will Rowe]
446 *) Fix segfaults for configuration file syntax errors such as
447 "<Directory>" followed by "</Directory" and
448 "<Directory>" followed by "</Directoryz>". [Jeff Trawick]
450 *) Cleanup the --enable-layout option of configure. This makes
451 us use a consistent location for the config.layout file, and it
452 makes configure more portable.
453 [jun-ichiro hagino <itojun@iijlab.net>]
455 *) Changes to 'ab'; fixed int overrun's, added statistics, output in
456 csv/gnuplot format, rudimentary ssl support and various other tweaks
457 to make results more true to what is measured. The upshot of this it
458 turns out that 'ab' has often underreported the true performance of
459 apache. Often by a order of magnitude :-) See talk/paper of Sander
460 Temme <sctemme@covalent.net> at April ApacheCon 2001 for details.
461 [Dirk-Willem van Gulik]
463 *) Clean up mod_cgid's temporary request pool. Besides fixing a
464 storage leak this ensures that some unnecessary pipes are closed.
467 *) Performance: Add quick_handler hook. This hook is called at the
468 very beginning of the request processing before location_walk,
469 translate_name, etc. This hook is useful for URI keyed content
470 caches like Mike Abbott's Quick Shortcut Cache.
473 *) top_module global variable renamed to ap_top_module [Perl]
475 *) Move ap_set_last_modified to the core. This is a potentially
476 controversial change, because this is kind of HTTP specific. However
477 many protocols should be able to take advantage of this kind of
478 information. I expect that headers will need one more layer of
479 indirection for multi-protocol work, but this is a small step in
480 the right direction. [Ryan Bloom]
482 *) Enable mod_status by default. This matches what Apache 1.3 does.
485 *) Add a ScriptSock directive to the default config file. This is
486 only enabled when mod_cgid is used.
487 [Taketo Kabe <kabe@sra-tohoku.co.jp>]
489 Changes with Apache 2.0.15
491 *) Untangled the buildconf script and eliminated the need for build's
492 aclocal.m4, generated_lists, build.mk, build2.mk, and a host of other
493 libtool muck that is now under srclib/apr/build. [Roy Fielding]
495 *) Win32: Don't accept more connections than we have worker threads
499 *) Fix bug in the Unix threaded.c MPM that allowed child processes
500 to fork() new child processes.
503 *) Fix a major security problem with double-reverse lookup checking.
504 Previously, a client connecting over IPv4 would not be matched
505 properly when the server had an IPv6 listening socket. PR #7407
506 [Taketo Kabe <kiabe@sra-tohoku.co.jp>]
508 *) Change the way the beos MPM handles polling to allow it to stop and
509 restart. Problem was the sockets being polled were being reset by
510 the select call, so once it had accepted a connection it was no
511 longer listening on the UDP socket we use for shutdown instructions.
512 APR needs to be altered, patch on it's way. [David Reid]
514 *) Empty out the brigade shared by ap_getline()/ap_get_client_block()
515 on error exit from ap_getline(). Some other code got upset because
516 the wrong data was in the brigade. [Greg Ames, Jeff Trawick]
518 *) Handle ap_discard_request_body() being called more than once.
519 [Greg Ames, Jeff Trawick]
521 *) Get rid of an inadvertent close of file descriptor 2 in
522 mod_mime_magic. [Greg Ames, Jeff Trawick]
524 *) Add a hook, create_request. This hook allows modules to modify
525 a request while it is being created. This hook is called for all
526 request_rec's, main request, sub request, and internal redirect.
527 When this hook is called, the the r->main, r->prev, r->next
528 pointers have been set, so modules can determine what kind of
529 request this is. [Ryan Bloom]
531 *) Cleanup the build process a bit more. The Apache configure
532 script no longer creates its own helper scripts, it just
534 [jean-frederic clere <jfrederic.clere@fujitsu-siemens.com>]
536 *) Stop the forced downgrade of the connection to HTTP/1.0 for
537 proxy requests. [Graham Leggett]
539 *) Avoid using sscanf to determine the HTTP protocol number in
540 the common case because sscanf is a performance hog. From
541 Mike Abbot's Accelerating Apache patch number 6.
542 [Mike Abbot <mja@trudge.engr.sgi.com>, Bill Stoddard]
544 *) Fix a security exposure in mod_access. Previously when IPv6
545 listening sockets were used, allow/deny-from-IPv4-address rules
546 were not evaluated properly (PR #7407). Also, add the ability to
547 specify IPv6 address strings with optional prefix length on Allow
548 and Deny. [Jeff Trawick]
550 *) Enhance rotatelogs so that a UTC offset can be specified, and
551 the logfile name can be formatted using strftime(3). (Brought
552 forward from 1.3.) [Ken Coar]
554 *) Reimplement the Windows MPM (mpm_winnt.c) to eliminate calling
555 DuplicateHandle on an IOCompletionPort (a practice which
556 MS "discourages"). The new model does not rely on associating
557 the completion port with the listening sockets, thus the
558 completion port can be completely managed within the child
559 process. A dedicated thread accepts connections off the network,
560 then calls PostQueuedCompletionStatus() to wake up worker
561 threads blocked on the completion port.
564 *) Bring forward the --suexec-umask option which allows the
565 builder to preset the umask for suexec processes. [Ken Coar]
567 *) Add a -V flag to suexec, which causes it to display the
568 compile-time settings with which it was built. (Only
569 usable by root or the AP_HTTPD_USER username.) [Ken Coar]
571 *) Mod_include should always unset the content-length if the file is
572 going to be passed through send_parsed_content. There is no to
573 determine if the content will change before actually scanning the
574 entire content. It is far safer to just remove the C-L as long
575 as we are scanning it. [Ryan Bloom]
577 *) Make sure Apache sends WWW-Authenticate during a reverse proxy
578 request and not Proxy-Authenticate.
579 [Graham Leggett <minfrin@sharp.fm>]
581 Changes with Apache 2.0.14
583 *) Fix content-length computation. We ONLY compute a content-length if
584 We are not in a 1.1 request and we cannot chunk, and this is a keepalive
585 or we already have all the data. [Ryan Bloom]
587 *) Report unbounded containers in the config file. Previously, a typo
588 in the </container> directive could result in the rest of the config
589 file being silently ignored, with undesired defaults used.
592 *) Make the old_write filter use the ap_f* functions for the buffering.
595 *) Move more code from the http module into the core server. This
596 is core code, basically the default handler, the default input
597 and output filters, and all of the core configuration directives.
598 All of this code is required in order for the server to work, with or
599 without HTTP. The server is closer to working without the HTTP
600 module, although there is still more to do. [Ryan Bloom]
602 *) Fix a number of SGI compile warnings throughout the server. Fix some
603 bad parameters to apr_bucket_read(). Fix a bad statement in
604 ap_method_in_list(). For the mod_rewrite cache use apr_time_t
605 consistently; we were mixing apr_time_t and time_t in invalid ways
606 before. In load_file(), call apr_dso_error() instead of
607 apr_strerror() so that we get a more specific string on some platforms.
608 PR #6980 [Jeff Trawick]
610 *) Allow modules to query the MPM about it's execution profile. This
611 query API can and should be extended in the future, but for now,
612 max_daemons, and threading or forking is a very good start.

615 *) Modify mod_include to send blocks of data no larger than 9k.
616 Without this, mod_include will wait until the whole file is parsed,

631 is to have only functions that are HTTP specific in the http directory.
634 Changes with Apache 2.0.13
636 *) Don't assume that there will always be multiple calls to the byterange
637 filter. It is possible that we will need to do byteranges with only
638 one call to the filter. [Ryan Morgan <rmorgan@covalent.net>]
640 *) Move the error_bucket definition from the http module to the
641 core server. Every protocol will need this ability, not just

668 APR thread functions. [Ryan Bloom]
670 *) Close one copy of the CGI's stdout before creating the new process.
671 The CGI will still have stdout, because we have already dup'ed it.

673 process that has forked a long-lived child process.

677 This requires the APR support for a signal thread that was just
680 *) Make mod_dir use a fixup for sending a redirect to the browser.
681 Before this, we were using a handler, which doesn't make much
682 sense, because the handler wasn't generating any data, it would
683 either return a redirect error code, or DECLINED. This fits the
684 current hooks better. [Ryan Morgan <rmorgan@covalent.net>]
686 *) Make the threaded MPM use APR threads instead of pthreads.
689 *) Get mod_tls to the point where it actually appears to work in all cases.
692 *) implement --enable-modules and --enable-mods-shared for "all" and
695 *) Move the threaded MPM to use APR locks instead of pthread locks.
698 *) Rename mpmt_pthread to threaded. This is more in line with the
699 fact that mpmt_pthread shouldn't be using pthreads directly, and
700 it is a smaller name that doesn't tie into anything.
703 *) Rename the module structures so that the exported symbol matches
704 the file name, and it is easier to automate the installation
705 process (generating LoadModule directives from the module filenames).
708 *) Remove the coalesce filter. With the ap_f* functions, this filter
709 is no longer needed. [Ryan Bloom]
711 Changes with Apache 2.0.11
713 *) Remove the dexter MPM. Perchild is the same basic idea, but it has the
714 added feature of allowing a uid/gid per child process. If no
715 uid/gid is specified, then Perchild behaves exactly like dexter.
718 *) Get perchild building again. [Ryan Bloom]
720 *) Don't disable threads just because we are using the prefork MPM.
721 If somebody wants to compile without threads, they must now add
722 --disable-threads to the configure command line. [Ryan Bloom]
724 *) Begin to move the calls to update_child_status into common code, so
725 that each individual MPM does not need to update the scoreboard itself.
728 *) Allow mod_tls to compile under Unix boxes where openssl has been
729 installed to the system include files.
730 [Gomez Henri <new-httpd@slib.fr>]
732 *) Cleanup the mod_tls configure process. This should remove any need
733 to hand-edit any files. We require OpenSSL 0.9.6 or later, but
734 configure doesn't check that yet. [Ryan Bloom]
736 *) Add a very early prototype of SSL support (in mod_tls.c). It is
737 vital that you read modules/tls/README before attempting to build
740 *) Fix a potential seg fault on all platforms. David Reid fixed this
741 on BEOS, but the problem could happen anywhere, so we don't want
742 to #ifdef it. [Cliff Woolley <cliffwoolley@yahoo.com>]
744 *) Add new LogFormat directive, %D, to log time it takes to serve a
745 request in microseconds. [Bill Stoddard]
747 *) Change AddInputFilter and AddOutputFilter to SetInputFilter and
748 SetOutputFilter. This corresponds nicely with the other Set
749 directives, which operate on containers while the Add* directives
750 tend to work directly on extensions. [Ryan Bloom]
752 *) Cleanup the header handling a bit. This uses the apr_brigade_*
753 functions for the buffering so that we don't need to compute
754 the length of the headers before we actually create the header
757 *) Allow filters to buffer data using the ap_f* functions. These have
758 become macros that resolve directly to apr_brigade_*.
761 *) Get the Unix MPM's to do a graceful restart again. If we are going
762 to register a cleanup with ap_cleanup_scoreboard, then we have to
763 kill the cleanup with the same function, and that function can't be
766 *) Install all required header files. Without these, it was not
767 possible to compile some modules outside of the server.
770 *) Fix the AliasMatch directive in Apache 2.0. When we brought a patch
771 forward from 1.3 to 2.0, we missed a single line, which broke regex
772 aliases. [Ryan Bloom]
774 *) We have a poor abstraction in the protocol. This is a temporary
775 hack to fix the bug, but it will need to be fixed for real. If
776 we find an error while sending out a custom error response, we back
777 up to the first non-OK request and send the data. Then, when we send
778 the EOS from finalize_request_protocol, we go to the last request,
779 to ensure that we aren't sending an EOS to a request that has already
780 received one. Because the data is sent on a different request than
781 the EOS, the error text never gets sent down the filter stack. This
782 fixes the problem by finding the last request, and sending the data
783 with that request. [Ryan Bloom]
785 *) Make the server status page show the correct restart time, and
786 thus the proper uptime. [Ryan Bloom]
788 *) Move the CGI creation logic from mod_include to mod_cgi(d). This
789 should reduce the amount of duplicate code that is required to
790 create CGI processes.

817 *) Make mod_cgid work with SuExec. [Ryan Bloom]
819 *) Adopt apr user/group name features for mod_rewrite. Eliminates some
820 'extra' stat's for user/group since they should never occur, and now
821 resolves the SCRIPT_USER and SCRIPT_GROUP, including on WinNT NTFS
822 volumes. [William Rowe]
824 *) Adopt apr features to simplify mod_includes. This changes the
825 behavior of the USER_NAME variable, unknown uid's are now reported
826 as USER_NAME="<unknown>" rather than the old user#000 result.
827 WinNT now resolves USER_NAME on NTFS volumes. [William Rowe]
829 *) Adopt apr features for simplifing mod_userdir, and accept the new
830 Win32/OS2 exceptions without hiccuping. [William Rowe]
832 *) Replace configure --with-optim option by using and saving the
833 environment variable OPTIM instead. This is needed because configure
834 options do not support multiple flags separated by spaces.
837 *) Fix some byterange handling. If we get a byte range that looks like
838 "-999999" where that is past the end of the file, we should return
839 a PARTIAL CONTENT status code, and return the whole file as one big
840 byterange. This matches the 1.3 handling now. [Ryan Bloom]
842 *) Make the error bucket a real meta-data bucket. This means that the
843 bucket length is 0, and a read returns NULL data. If one of these
844 buckets is passed down after the headers are sent, this data will
845 just be ignored. [Greg Stein]
847 *) The prefork MPM wasn't killing child processes correctly if a restart
848 signal was received while the process was serving a request. The child
849 process would become the equivalent of a second parent process. If
850 we break out of the accept loop, then we need to do die after cleaning
851 up after ourselves. [Ryan Bloom]
853 *) Change the Prefork MPM to use SIGWINCH instead of SIGUSR1 for graceful
854 restarts. [Ryan Bloom]
856 *) Modify the apr_stat/lstat/getfileinfo calls within apache to use
857 the most optimal APR_FINFO_wanted bits. This spares Win32 from
858 performing very expensive owner, group and permission lookups
859 and allows the server to function until these apr_finfo_t fields
860 are implemented under Win32. [William Rowe]
862 *) Support for typedsafe optional functions - that is functions exported by
863 optional modules, which, therefore, may or may not be present, depending
864 on configuration. See the experimental modules mod_optional_fn_{ex,im}port
865 for sample code. [Ben Laurie]
867 *) filters can now report an HTTP error to the server. This is done
868 by sending a brigade where the first bucket is an error_bucket.
869 This bucket is a simple bucket that stores an HTTP error and
870 a string. Currently the string is not used, but it may be needed
871 to output an error log. The http_header_filter will find this
872 bucket, and output the error text, and then return
873 AP_FILTER_ERROR, which informs the server that the error web page
874 has already been sent. [Ryan Bloom]
876 *) If we get an error, then we should remove all filters except for
877 those critical to serving a web page. This fixes a bug, where
878 error pages were going through the byterange filter, even though
879 that made no sense. [Ryan Bloom]
881 *) Relax the syntax checking of Host: headers in order to support
882 iDNS. PR#6635 [Tony Finch]
884 *) Cleanup the byterange filter to use the apr_brigade_partition
885 and apr_bucket_copy functions. This removes a lot of very messy
886 code, and hopefully makes this filter more stable.
889 *) Remove AddModule and ClearModuleList directives. Both of these
890 directives were used to ensure that modules could be enabled
891 in the correct order. That requirement is now gone, because
892 we use hooks to ensure that modules are in the correct order.
895 *) When SuExec is specified, we need to add it to the list of
896 targets to be built. If we don't, then any changes to the
897 configuration won't affect SuExec, unless 'make suexec' is
898 specifically run. [Ryan Bloom]
900 *) Cleaned out open_file from mod_file_cache, as apr now accepts
901 the APR_XTHREAD argument to open a file for consumption by
902 parallel threads on win32. [William Rowe]
904 *) Correct a bug in determining when we follow symlinks. The code
905 expected a stat -1 result, not an apr_status_t positive error.
906 Also check if the APR_FINFO_USER fields are valid before we
907 follow the link. [William Rowe]
909 *) Move initgroupgs, ap_uname2id and ap_gname2id from util.c to
910 mpm_common.c. These functions are only valid on some platforms,
911 so they should not be in the main-line code. [Ryan Bloom]
913 *) Remove ap_chdir_file(). This function is not thread-safe,
914 and nobody is currently using it. [Ryan Bloom]
916 *) Do not try to run make depend if there are no .c files in the
917 current directory, doing so makes `make depend` fail.
920 *) Update highperformance.conf to work with either prefork or
921 pthreads mpms. [Greg Ames]
923 *) Stop checking to see if this is a pipelined request if we know
924 for a fact that it isn't. Basically, if r->connection->keepalive == 0.
925 This keeps us from making an extra read call when serving a 1.0
926 request. [Ryan Bloom and Greg Stein]
928 *) Fix the handling of variable expansion look-ahead in mod_rewrite,
929 i.e. syntax like %{LA-U:REMOTE_USER}, and also fix the parsing of
930 more complicated nested RewriteMap lookups. PR#7087 [Tony Finch]

933 Host: header. PR#7079 [Alexey Toptygin <alexeyt@wam.umd.edu>]

939 *) Fix a segfault while handling request bodies in ap_http_filter().
940 This problem has been seen with mod_dav usage as well as with
941 requests where the body was just being discarded. [Jeff Trawick]
943 *) Some adjustment on the handling and automatic setting (via
944 hints.m4) of various compilation flags (eg: CFLAGS). Also,
945 add the capability to specify flags (NOTEST_CFLAGS and
946 NOTEST_LDFLAGS) which are used to compile Apache, but
947 not used during the configuration process. Useful for
948 flags like "-Werror". [Jim Jagielski]
950 *) Stop using environment variables to force debug mode or
951 no detach. We now use the -D command line argument to
952 specify the correct mode. -DONE_PROCESS and -DNO_DETACH.
953 [Greg Stein, Ryan Bloom]
955 *) Change handlers to use hooks. [Ben Laurie]
957 *) Stop returning copies of filenames from both apr_file_t and
958 apr_dir_t. We pstrdup the filenames that we store in the
959 actual structures, so we don't need to pstrdup the strings again.
962 *) mod_cgi: Fix some problems where the wrong error value was being
963 traced. [Jeff Trawick]
965 *) EBCDIC: Fix some missing ASCII conversion on some protocol data.
968 *) Add generic hooks. [Ben Laurie]
970 *) Use a real pool to dup the error log descriptor. [Ryan Bloom]
972 *) Fix a segfault caused by mod_ext_filter when the external filter
973 program does not exist. [Jeff Trawick]
975 *) Fix an output truncation error when on an HTTP >= 1.0 request an
976 object of size between DEFAULT_BUCKET_SIZE and AP_MIN_BYTES_TO_WRITE
977 was served through mod_charset_lite (or anything else that would
978 create a transient bucket in this size range). ap_bucket_make_heap()
979 silently failed (fixed), transient_setaside() discovered it, but
980 ap_save_brigade() ignored it (fixed). [Jeff Trawick]
982 *) Ignore \r\n or \n when using PEEK mode for input filters. The problem
983 is that some browsers send extra lines at the end of POST requests, and
984 we don't want to delay sending data back to the user just because the
985 browser isn't well behaved. [Ryan Bloom]
987 *) Get SuEXEC working again. We can't send absolute paths to suExec
988 because it refuses to execute those programs. SuEXEC also wasn't
989 always recognizing configuration changes made using the autoconf
992 *) Allow the buildconf process to find the config.m4 files in the correct
993 order. Basically, we can now name config.m4 files as config\d\d.m4,
994 and we will sort them correctly when inserting them into the build
995 process. [Ryan Bloom]
997 *) Get mod_cgid to use apr calls for creating the actual CGI process.
998 This also allows mod_cgid to use ap_os_create_priviledged_process,
999 thus allowing for SuExec execution from mod_cgid. Currently, we do
1000 not support everything that standard SuExec supports, but at least
1001 it works minimally now. [Ryan Bloom]
1003 *) Allow SuExec to be configured from the ./configure command line.
1006 *) Update some of the docs in README and INSTALL to reflect some of
1007 the changes in Apache 2.0 [Cliff Woolley <cliffwoolley@yahoo.com>]
1009 *) If we get EAGAIN returned from the call to apr_sendfile, then we
1010 need to call sendfile again. This gets us serving large files
1011 such as apache_2.0a9.tar.gz on FreeBSD again. [Ryan Bloom]
1013 *) Get the support programs building cleanly again.
1014 [Cliff Woolley <cliffwoolley@yahoo.com>]
1016 *) The Apache/Win32 Apache.exe and dll's now live in bin. The
1017 current directory logic now backs up over bin/ to determine the
1018 server root from the Apache.exe path.
1020 *) Apache/Win32 now follows the standard conventions of mod_foo.so
1021 loadable modules, dynamic libs are all named libfoo.dll, and the
1022 makefile.win populates the include, lib and libexec directories.
1024 *) Apache is now IPv6-capable. On systems where APR supports IPv6,
1025 Apache gets IPv6 listening sockets by default. Additionally, the
1026 Listen, NameVirtualHost, and <VirtualHost> directives support IPv6
1027 numeric address strings (e.g., "Listen [fe80::1]:8080").
1030 *) Modify the install directory layout. Modules are now installed in
1031 modules/. Shared libraries should be installed in libraries/, but
1032 we don't have any of those on Unix yet. All install directories
1033 are modifyable at configure time. [Ryan Bloom]
1035 *) Install all header files in the same directory on Unix. [Ryan Bloom]
1037 *) Get the functions in server/linked into the server, regardless of
1038 which modules linked into the server. This uses the same hack
1039 for Apache that we use for APR and apr-util to ensure all of the
1040 necessary functions are linked. As a part of thise, the CHARSET_EBCDIC
1041 was renamed to AP_CHARSET_EBCDIC for namespace protection, and to make
1042 the scripts a bit easier.
1045 *) Rework the RFC1413 handling to make it thread-safe, use a timeout
1046 on the query, and remove IPv4 dependencies. [Jeff Trawick]
1048 *) Get all of the auth modules to the point that they will install and
1049 be loadable into the server. Our new build/install mechanism expects
1050 that all modules will have a common name format. The auth modules
1051 didn't use that format, so we didn't install them properly.
1054 *) API routines ap_pgethostbyname() and ap_pduphostent() are no longer
1055 available. Use apr_getaddrinfo() instead. [Jeff Trawick]
1057 *) Get "NameVirtualHost *" working in 2.0. [Ryan Bloom]
1059 *) Return HTTP_RANGE_NOT_SATISFIABLE if the every range requested starts
1060 after the end of the response. [Ryan Bloom]
1062 *) Get byterange requests working with responses that do not have a
1063 content-length. Because of the way byterange requests work, we have to
1064 have all of the data before we can actually do the byterange, so we
1065 can compute the content-length in the byterange filter.
1068 *) Get exe CGI's working again on Windows.
1071 *) Get mod_cgid and mod_rewrite to work as DSOs by changing the way
1072 they keep track of whether or not their post config hook has been
1073 called before. Instead of a static variable (which is replaced when
1074 the DSO is loaded a second time), use userdata in the process pool.
1077 Changes with Apache 2.0a9
1079 *) Win32 now requires perl to complete the final install step for users
1080 to build + install on Win32. Makefile.win now rewrites @@ServerRoot@
1081 and installs the conf, htdocs and htdocs/manual directories.
1084 *) Make mod_include use a hash table to associate directive tags with
1085 functions. This allows modules to implement their own SSI tags easily.
1086 The idea is simple enough, a module can insert it's own tag and function
1087 combination into a hash table provided by mod_include. While mod_include
1088 parses an SSI file, when it encounters a tag in the file, it does a
1089 hash lookup to find the function that implements that tag, and passes
1090 all of the relevant data to the function. That function is then
1091 responsible for processing the tag and handing the remaining data back
1092 to mod_include for further processing.
1093 [Paul J. Reder <rederpj@raleigh.ibm.com>]
1095 *) Get rid of ap_new_apr_connection(). ap_new_connection() now has
1096 fewer parameters: the local and remote socket addresses were removed
1097 from the parameter list because all required information is available
1098 via the APR socket. [Jeff Trawick]
1100 *) Distribution directory structure reorganized to reflect a
1101 normal source distribution with external install targets.
1104 *) The MPMs that need multiple segments of shared memory now create
1105 two apr_shmem_t variables, one for each shared memory allocation.
1106 the problem is that we can't determine how much memory will be required
1107 for shared memory allocations once we try to allocate more than one
1108 variable. The MM code automatically aligns the shared memory allocations,
1109 so we end up needing to pad the amount of shared memory we want based
1110 on how many variables will be allocated out of the shared memory segment.
1111 It is just easier to create a second apr_shmem_t variable, and two
1112 shmem memory blocks.
1115 *) Cleanup the export list a bit. This creates a single unified list of
1116 functions exported by APR. The export list is generated at configure
1117 time, and that list is then used to generate the exports.c file.
1118 Because of the way the export list is generated, we only export those
1119 functions that are valid on the platform we are building on.
1122 *) Enable logging the cookie with mod_log_config
1123 [Sander van Zoest <sander@covalent.net>]
1125 *) Fix a segfault in mod_info when it reaches the end of the configuration.
1128 *) Added lib/aputil/ as a placeholder for utility functions which are not
1129 specific to the Apache HTTP Server (but do not make sense with APR).
1130 The first utility is "apu_dbm": a set of functions to work with DBM
1131 files. This first version can be compiled for SDBM or GDBM databases.
1134 *) Complete re-write of mod_include. This makes mod_include a filter that
1135 uses buckets directly. This has now served the FAQ correctly.
1136 [Paul Reder <rederpj@raleigh.ibm.com>]
1138 *) Allow modules to specify the first filter in a sub_request when
1139 making the sub_request. This keeps modules from having to change the
1140 output_filter immediately after creating the sub-request, and therefore
1141 skip the sub_req_output_filter. [Ryan Bloom]
1143 *) Update ab to accept URLs with IPv6 literal address strings (in the
1144 format described in RFC 2732), and to build Host header fields in
1145 the same format. This allows IPv6 literal address strings to be
1146 used with ab. This support has been tested against Apache 1.3 with
1147 the KAME patch, but Apache 2.0 does not yet work with this format
1148 of the Host header field. [Jeff Trawick]
1150 *) Accomodate an out-of-space condition in the piped logs and the
1151 rotatelogs.c code, and no longer churn log processes for this
1152 condition. [Victor J. Orlikowski]
1154 *) Add support for partial writes with apr_sendfile() to core_output_filter.
1157 Changes with Apache 2.0a8
1159 *) Add a directive to mod_mime so that filters can be associated with
1163 *) Get multi-views working again. We were setting the path_info
1164 field incorrectly if we couldn't find the specified file.
1167 *) Fix 304 processing. The core should never try to send the headers
1168 down the filter stack. Always, just setup the table in the request
1169 record, and let the header filter convert it to data that is ready
1173 *) More fixes for the proxy. There are still bugs in the proxy code,
1174 but this has now proxied www.yahoo.com and www.ntrnet.net (my ISP)
1178 *) Fix params for apr_getaddrinfo() call in connect proxy handler.
1181 *) APR: Add new apr_getopt_long function to handle long options.
1182 [B. W. Fitzpatrick <fitz@red-bean.com>]
1184 *) APR: Change apr_connect() to take apr_sockaddr_t instead of hostname.
1185 Add generic apr_create_socket(). Add apr_getaddrinfo() for doing
1186 hostname resolution/address string parsing and building
1187 apr_sockaddr_t. Add apr_get_sockaddr() for getting the address
1188 of one of the apr_sockaddr_t structures for a socket. Change
1189 apr_bind() to take apr_sockaddr_t. [David Reid and Jeff Trawick]
1191 *) Remove the BUFF from the HTTP proxy. This is still a bit ugly, but
1192 I have proxied pages with it, cleanup will commence soon.
1195 *) Make the proxy work with filters. This isn't perfect, because we
1196 aren't dealing with the headers properly. [Ryan Bloom]
1198 *) Do not send a content-length iff the C-L is 0 and this is a head
1199 request. [Ryan Bloom]
1201 *) Make cgi-bin work as a regular directory when using mod_vhost_alias
1202 with no VirtualScriptAlias directives. PR#6829 [Tony Finch]
1204 *) Remove BUFF from the PROXY connect handling. [Ryan Bloom]
1206 *) Get the default_handler to stop trying to deal with HEAD requests.
1207 The idea is to let the content-length filter compute the C-L before
1208 we try to send the data. If we can get the C-L correctly, then we
1209 should send it in the HEAD response.
1212 *) The Header filter can now determine if a body should be sent based
1213 on r->header_only. The general idea of this is that if we delay
1214 deciding to send the body, then we might be able to compute the
1215 content-length correctly, which will help caching proxies to cache
1216 our data better. Any handler that doesn't want to try to compute
1217 the content-length can just send an EOS bucket without data and
1218 everything will just work.
1221 *) Add the referer to the error log if one is available.
1222 [Markus Gyger <mgyger@itr.ch>]
1224 *) Mod_info.c has now been ported to Apache 2.0. As a part of this
1225 change, the root of the configuration tree has been exposed to modules
1227 [Ryan Morgan <rmorgan@covalent.net>]
1229 *) Get the core_output_filter to use the bucket interface directly.
1230 This keeps us from calling the content-length filter multiple times
1231 for a simple static request.
1234 *) We are sending the content-type correctly now.
1235 [Ryan Bloom and Will Rowe]
1237 *) APR on FreeBSD: Fix a bug in apr_sendfile() which caused us to report
1238 a bogus bytes-sent value when the only thing being sent was trailers
1239 and writev() returned an error (or EAGAIN). [Jeff Trawick]
1241 *) Get SINGLE_LISTEN_UNSERIALIZED_ACCEPT working again. This uses the
1242 hints file to determine which platforms define
1243 SINGLE_LISTEN_UNSERIALIZED_ACCEPT.
1246 *) APR: add apr_get_home_directory() [Jeff Trawick]
1248 *) Initial import of 1.3-current mod_proxy. [Chuck Murcko]
1250 *) Not all platforms have INADDR_NONE defined by default. Apache
1251 used to make this check and define INADDR_NONE if appropriate,
1252 but APR needs the check too, and I suspect other applications will
1253 as well. APR now defines APR_INADDR_NONE, which is always a valid
1254 value on all platforms.
1255 [Branko Èibej <brane@xbc.nu>]
1257 *) Destroy the pthread mutex in lock_intra_cleanup() for PR#6824.
1258 [Shuichi Kitaguchi <ki@hh.iij4u.or.jp>]
1260 *) Relax the syntax checking of Host: headers in order to support
1261 iDNS. PR#6635 [Tony Finch]
1263 *) When reading from file buckets we convert to an MMAP if it makes
1264 sense. This also simplifies the default handler because the
1265 default handler no longer needs to try to create MMAPs.
1268 *) BUFF has been removed from the main server. The BUFF code will remain
1269 in the code until it has been purged from the proxy module as well.
1272 *) Byteranges have been completely re-written to be a filter. This
1273 has been tested, and I believe it is working correctly, but it could
1274 doesn't work for the Adobe Acrobat plug-in. The output almost matches
1275 the output from 1.3, the only difference being that 1.3 includes
1276 a content-length in the response, and this does not.
1279 *) APR read/write functions and bucket read functions now operate
1280 on unsigned integers, instead of signed ones. It doesn't make
1281 any sense to use signed ints, because we return the error codes,
1282 so if we have an error we should report 0 bytes read or written.
1285 *) Always compute the content length, whether it is sent or not.
1286 The reason for this, is that it allows us to correctly report
1287 the bytes_sent when logging the request. This also simplifies
1288 content-length filter a bit, and fixes the actual byte-reporing
1289 code in mod_log_config.c
1292 *) Remove AP_END_OF_BRIGADE definition. This does not signify what
1293 it says, because it was only used by EOS and FLUSH buckets. Since
1294 neither of those are required at the end of a brigade, this was
1295 really signifying FLUSH_THE_DATA, but that can be determined better
1296 by checking AP_BUCKET_IS_EOS() or AP_BUCKET_IS_FLUSH. EOS and FLUSH
1297 buckets now return a length of 0, which is actually the amount of data
1298 read, so they make more sense.
1301 *) Allow the core_output_filter to save some data past the end of a
1302 request. If we get an EOS bucket, we only send the data if it
1303 makes sense to send it. This allows us to pipeline request
1304 responses. As a part of this, we also need to allocate mmap
1305 buckets out of the connection pool, not the request pool. This
1306 allows the mmap to outlive the request.
1309 *) Make blocking and non-blocking bucket reads work correctly for
1310 sockets and pipes. These are the only bucket types that should
1311 have non-blocking reads, because the other bucket types should
1312 ALWAYS be able to return something immediately.
1315 *) In the Apache/Win32 console window, accept Ctrl+C to stop the
1316 server, but use Ctrl+Break to initiate a graceful restart
1317 instead of duplicating behavior. [John Sterling]
1319 *) Patch mod_autoindex to set the Last-Modified header based on
1320 the directory's mtime, and add the ETag header. [William Rowe]
1322 *) Merge the 1.3 patch to add support for logging query string in
1323 such a way that "%m %U%q %H" is the same as "%r".
1326 *) Port three log methods from mod_log_config 1.3 to 2.0:
1327 CLF compliant '-' byte count, method and protocol.
1330 *) Add a new LogFormat directive, %c, that will log connection
1331 status at the end of the response as follows:
1332 'X' - connection aborted before the response completed.
1333 '+' - connection may be kept-alive by the server.
1334 '-' - connection will be closed by the server.
1337 *) Expand APR for WinNT to fully accept and return utf-8 encoded
1338 Unicode file names and paths for Win32, and tag the Content-Type
1339 from mod_autoindex to reflect that charset if the the feature
1340 macro APR_HAS_UNICODE_FS is true. [William Rowe]
1342 *) Compute the content length (and add appropriate header field) for
1343 the response when no content length is available and we can't use
1344 chunked encoding. [Jeff Trawick]
1346 *) Changed ap_discard_request_body() to use REQUEST_CHUNKED_DECHUNK,
1347 so that content input filters get dechunked data when using
1348 the default handler. Also removed REQUEST_CHUNKED_PASS.
1351 *) Add mod_ext_filter as an experimental module. This module allows
1352 the administrator to use external programs as filters. Currently,
1353 only filtering of output is supported. [Jeff Trawick]
1355 *) Most Apache functions work on EBCDIC machines again, as protocol
1356 data is now translated (again). [Jeff Trawick]
1358 *) Introduce ap_xlate_proto_{to|from}_ascii() to clean up some of
1359 the EBCDIC support. They are noops on ASCII machines, so this
1360 type of translation doesn't have to be surrounded by #ifdef
1361 CHARSET_EBCDIC. [Jeff Trawick]
1363 *) Fix mod_include. tag commands work again, and the server will
1364 send the FAQ again. This also allows mod_include to set aside
1365 buckets that include partial buckets.
1366 [Ryan Bloom and David Reid]
1368 *) Add suexec support back. [Manoj Kasichainula]
1370 *) Lingering close now uses the socket directly instead of using
1371 BUFF. This has been tested, but since all we can tell is that it
1372 doesn't fail, this needs to be really hacked on.
1375 *) Allow filters to modify headers and have those headers be sent to
1376 the client. The idea is that we have an http_header filter that
1377 actually sends the headers to the network. This removes the need
1378 for the BUFF to send headers.
1381 *) Charset translation: mod_charset_lite handles translation of
1382 request bodies. Get rid of the xlate version of ap_md5_digest()
1383 since we don't compute digests of filtered (e.g., translated)
1384 response bodies this way anymore. (Note that we don't do it at
1385 all at the present; somebody needs to write a filter to do so.)
1388 *) Input filters and ap_get_brigade() now have a input mode parameter
1389 (blocking, non-blocking, peek) instead of a length parameter.
1392 *) Update the mime.types file to the registered media types as
1393 of 2000-10-19. PR#6613 [Carsten Klapp <carsten.klapp@home.net>,
1396 *) Namespace protect some macros declared in ap_config.h
1399 *) Support HTTP header line folding with input filtering.
1402 *) Mod_include works again. This should still be re-written, but at
1403 least now we can serve an SHTML page again.
1406 *) Begin to remove BUFF from the core. Currently, we keep a pointer
1407 to both the BUFF and the socket in the conn_rec. Functions that
1408 want to use the BUFF can, functions that want to use the socket,
1409 can. They point to the same place.
1412 *) apr_psprintf doesn't understand %lld as a format. Make it %ld.
1413 [Tomas "Ögren" <stric@ing.umu.se>]
1415 *) APR pipes on Unix and Win32 are now cleaned up automatically when the
1416 associated pool goes away. (APR pipes on OS/2 were already had this
1417 logic.) This resolvs a fatal file descriptor leak with CGIs.
1420 *) The final line of the config file was not being read if there was
1421 no \n at the end of it. This was caused by apr_fgets returning
1422 APR_EOF even though we had read valid data. This is solved by
1423 making cfg_getline check the buff that was returned from apr_fgets.
1424 If apr_fgets return APR_EOF, but there was data in the buf, then we
1425 return the buf, otherwise we return NULL.
1428 *) Piped logs work again in the 2.0 series.
1431 *) Restore functionality broken by the mod_rewrite security fix:
1432 rewrite map lookup keys and default values are now expanded
1433 so that the lookup can depend on the requested URI etc.
1434 PR #6671 [Tony Finch]
1436 *) Tighten up the syntax checking of Host: headers to fix a
1437 security bug in some mass virtual hosting configurations
1438 that can allow a remote attacker to retrieve some files
1439 on the system that should be inaccessible. [Tony Finch]
1441 *) Add a pool bucket type. This bucket is used for data allocated out
1442 of a pool. If the pool is cleaned before the bucket is destroyed, then
1443 the data is converted to a heap bucket, allowing it to survive the
1447 *) Add a flush bucket. This allows modules to signal that the filters
1448 should all flush whatever data they currently have. There is no way
1449 to actually force them to do this, so if a filter ignores this bucket,
1450 that's life, but at least we can try with this.
1453 *) Add an output filter for sub-requests. This filter just strips the
1454 EOS bucket so that we don't confuse the main request's core output
1455 filter by sending multiple EOS buckets. This change also makes sub
1456 requests start to send EOS buckets when they are finished.
1459 *) Make ap_bucket_(read|destroy|split|setaside) into macros. Also
1460 makes ap_bucket_destroy a return void, which is okay because it
1461 used to always return APR_SUCCESS, and nobody ever checked its
1462 return value anyway.
1463 [Cliff Woolley <cliffwoolley@yahoo.com>]
1465 *) Remove the index into the bucket-type table from the buckets
1466 structure. This has now been replaced with a pointer to the
1467 bucket_type. Also add some macros to test the bucket-type.
1470 *) Renamed all MODULE_EXPORT symbols to AP_MODULE_DECLARE and all symbols
1471 for CORE_EXPORT to AP_CORE_DECLARE (namespace protecting the wrapper)
1472 and retitled API_EXPORT as AP_DECLARE and APR_EXPORT as APR_DECLARE.
1473 All _VAR_ flavors changes to _DATA to be absolutely clear.
1476 *) Add support for /, //, //servername and //server/sharename
1477 parsing of <Directory> blocks under Win32 and OS2.
1478 [Tim Costello, William Rowe, Brian Harvard]
1480 *) Remove the function pointers from the ap_bucket type. They have been
1481 replaced with a global table. Modules are allowed to register bucket
1482 types and use then use those buckets.
1485 *) mod_cgid: In the handler, shut down the Unix socket (only for write)
1486 once we finish writing the request body to the cgi child process;
1487 otherwise, the client doesn't hit EOF on stdin. Small request bodies
1488 worked without this change (for reasons I don't understand), but large
1489 ones didn't. [Jeff Trawick]
1491 *) Remove file bucket specific information from the ap_bucket type.
1492 This has been moved to a file_bucket specific type that hangs off
1493 the data pointer in the ap_bucket type.
1496 *) Input filtering now has a third argument. This is the amount of data
1497 to read from lower filters. This argument can be -1, 0, or a positive
1498 number. -1 means give me all the data you have, I'll deal with it and
1499 let you know if I need more. 0 means give me one line and one line
1500 only. A positive number means I want no more than this much data.
1502 Currently, only 0 and a positive number are implemented. This allows
1503 us to remove the remaining field from the conn_rec structure, which
1507 *) Big cleanup of the input filtering. The goal is that http_filter
1508 understands two conditions, headers and body. It knows where it is
1509 based on c->remaining. If c->remaining is 0, then we are in headers,
1510 and http_filter returns a line at a time. If it is not 0, then we are
1511 in body, and http_filter returns raw data, but only up to c->remaining
1512 bytes. It can return less, but never more.
1513 [Greg Ames, Ryan Bloom, Jeff Trawick]
1515 *) mod_cgi: Write all of the request body to the child, not just what
1516 the kernel would accept on the first write. [Jeff Trawick]
1518 *) Back out the change that moved the brigade from the core_output_filters
1519 ctx to the conn_rec. Since all requests over a given connection
1520 go through the same core_output_filter, the ctx pointer has the
1524 *) Fix another bug in the send_the_file() read/write loop. A partial
1525 send by apr_send would cause unsent data in the read buffer to
1526 get clobbered. Complete making send_the_file handle partial
1527 writes to the network.
1530 *) Fix a couple of type fixes to allow compilation on AIX again
1531 [Victor J. Orlikowski <v.j.orlikowski@gte.net>]
1533 *) Fix bug in send_the_file() which causes offset to be ignored
1534 if there are no headers to send.
1537 *) Handle APR_ENOTIMPL returned from apr_sendfile in the core
1538 filter. Useful for supporting Windows 9* with a binary
1539 compiled on Windows NT.
1542 Changes with Apache 2.0a7
1544 *) Reimplement core_output_filter to buffer/save bucket brigades
1545 across multiple calls to the core_filter. The brigade will be
1546 sent when either MIN_BYTES_TO_SEND or MAX_IOVEC_TO_WRITE
1547 thresholds are hit or the EOS bucket is received.
1550 *) Create experimental filter (buffer_filter) that coalesces bytes
1551 into one large buffer before invoking the next filter in the
1552 chain. This filter is particularly useful with the current
1553 implementation of mod_autoindex when it inserted above the
1554 chunk_filter. mod_autoindex generates a lot of brigades that
1555 containing buckets holding just a few bytes each. The
1556 buffer_filter coalesces these buckets into a single large bucket.
1559 *) Add apr_sendfile() support into the core_output_filter.
1562 *) Add apr_sendv() support into the core_output_filter.
1565 *) Fix mod_log_config so that it compiles cleanly with BUFFERED_LOGS
1566 [Mike Abbott <mja@sgi.com>]
1568 *) Remove ap_send_fb. This is no longer used in Apache, and it doesn't
1569 make much sense, because Apache uses buckets instead of BUFFs now.
1572 *) send_the_file now falls back to a read/write loop on platforms that
1573 do not have sendfile.
1574 [Ryan Bloom and Brian Havard]
1576 *) Install apachectl correctly, and substitute the proper values so
1577 that it works again. [Ryan Bloom]
1579 *) Better(??) handle platforms that lack sendfile().
1582 *) APR now has UUID generation/formatting/parsing support.
1585 *) Begin the http_filter. This is an input filter that understands
1586 the absolute basic amount required to parse an HTTP Request. The
1587 goal is to be able to split headers from request body before passing
1588 the data back to the other filters.
1591 *) Bring forward from 1.3.13 the config directory implementation
1594 *) install apxs if it is created
1597 *) Added APR_IS_STATUS_condition test macros to eliminate canonical error
1598 conversions. [William Rowe]
1600 *) Now that we have ap_add_input_filter(), rename ap_add_filter() to
1601 ap_add_output_filter(). [Jeff Trawick]
1603 *) Multiple build and configuration fixes
1606 -add datadir and localstatedir substitutions
1608 -fix logfilename misspelling
1609 -fix evaluation of installation dir variables and
1610 -replace $foobar by $(foobar) to be usefull in the makefile
1614 -add rules for cross-compiling in rules.mk. Okay, rule to check for
1615 $CC_FOR_BUILD is still missing
1616 -use CHECK_TOOL instead of CHECK_PROG for ranlib
1617 -add missing "AR=@AR@" to severaly Makefile.in's
1618 -cache result for "struct rlimit"
1619 -compile all helper programs with native and cross compiler
1620 and use the native version to generate header file
1621 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1623 *) Prepare our autoconf setup for autoconf 2.14a and for cross-
1625 ["Rüdiger" Kuhlmann <Tadu@gmx.de>]
1627 *) Fix a bug where a client which only sends \n to delimit header
1628 lines (netcat) gets a strange looking HTTP_NOT_IMPLEMENTED
1629 message. Start working on ebcdic co-existance with input
1631 [William Rowe, Greg Ames]
1633 *) If mod_so is enabled in the server always create libexec, even
1634 if there are no modules installed in this directory. This is a
1635 requirement for APXS to work correctly.
1638 *) Connection oriented output filters are now stored in the
1639 conn_rec instead of the request_rec. This allows us to add the
1640 output filter in the pre-connection phase instead of the
1641 post_read_request phase, which keeps us from trying to write an
1642 error page before we have a filter to write to the network.
1643 [Ryan Bloom, Jeff Trawick, and Greg Ames]
1645 *) Cleaning up an mmap bucket no longer deletes the mmap. An
1646 mmap can be used across multiple buckets (default_handler with
1647 byte ranges, mod_file_cache, mod_mmap_static), so cleanup of
1648 the mmap itself can't be associated with the bucket.
1651 *) Add .dll caching directive ISAPICacheFile to mod_isapi.
1654 *) Radical surgery to improve mod_isapi support under Win32.
1655 Includes a number of newer ServerSupportFunction calls, support
1656 for ReadClient (in order to retrieve POSTs greater than 48KB),
1657 and general bug fixes to more reliably load ISAPI .dll's and
1658 prevent leaking handle resources. Note: There are still
1659 discrepancies between IIS's and Apache's ServerVariables, and
1660 async calls are still not supported. Additional warnings are
1661 logged to facilitate debugging of unsupported ISAPI calls.
1664 *) Add input filtering to Apache. The basic idea for the input
1665 filters is the same as the ideas for output filters. The biggest
1666 difference is that instead of calling ap_pass_brigade, ap_get_brigade
1667 should be called, and the order of execution for the filter itself is
1668 different. When writing an output filter, a brigade is passed in,
1669 and filters operate directly on that brigade, when done, they call
1670 ap_pass_brigade. Input filters are the exact opposite. Because input
1671 is not a push operation, filters first call ap_get_brigade. When this
1672 function returns, the input filter will be left with a valid brigade.
1673 The input filter should then operate on the brigade, and return.
1676 *) Fix building on BSD/OS using its native make. The build system
1677 falls back to the BSD .include directive on that host platform.
1680 *) Expand dbmmanage to allow -d -m -s -p options for Crypt, MD5,
1681 SHA1 and plaintext password encodings. Make feature tests a
1682 bit more flexible. [William Rowe]
1684 *) Charset translation: mod_charset_lite handles output content
1685 translation in a filter. mod_charset_lite no longer ignores
1686 subrequests. A bunch of cruft related to BUFF's support for
1687 translating request and response bodies was removed.
1690 *) Move the addition of the CORE filter to the post_read_request
1691 hook in http_core.c. This removes the need to add the filter in
1692 multiple places and allows for an SSL module to be added much
1693 simpler. [Ryan Bloom]
1695 *) Fix a security problem that affects certain configurations of
1696 mod_rewrite. If the result of a RewriteRule is a filename that
1697 contains expansion specifiers, especially regexp backreferences
1698 $0..$9 and %0..%9, then it may be possible for an attacker to
1699 access any file on the web server. [Tony Finch]
1701 *) Fix a bug where errors that are detected during early request parsing
1702 don't produce visible HTTP error messages at the browser, because
1703 the core_filter wasn't present. [Greg Ames]
1705 *) Provide apr_socklen_t as a portability aid.
1706 [Victor J. Orlikowski]
1708 *) Overhaul of dbmmanage to allow a groups arg (as in Apache 1.2)
1709 as well as a comment arg to the add, adduser and update cmds.
1710 update allows the user to clear or preserve pw/groups/comment.
1711 Fixed a bug in dbmmanage that prevented the check option from
1712 parsing a password followed by :group... text. Corrected the
1713 seed calcualation for Win32 systems, and added -lsdbm support.
1716 *) Configured mod_auth_dbm to compile with sdbmlib under Win32.
1719 *) Avoid a segfault when parsing .htaccess files. An
1720 uninitialized tree pointer was passed to ap_build_config().
1723 *) Change the way that inet_addr & inet_network are checked for
1724 in APR's configure process to allow BeOS BONE to correctly
1725 find them. With this change BeOS BONE now builds from source
1726 with no problems. [David Reid]
1728 *) Fix a bug in apr_create_process() for Unix. The NULL signifying
1729 the end of the parameters to execve() was stored in the wrong
1730 location, overlaying the storage beyond the newargs[] array and
1731 also passing uninitialized storage to execve(), which would
1732 sometimes fail with EFAULT. [Jeff Trawick]
1734 *) Fix a bug parsing configuration file containers. With a sequence
1735 like this in the config file
1737 <IfModule mod_kilroy.c>
1740 <IfModule mod_lovejoy.c>
1745 the second container would be terminated at the blank line due to
1746 sediment in the buffer from reading the prior </IfModule> and an
1747 error message would be generated for the real </IfModule> for the
1748 second container. Also due to this problem, any two characters
1749 could be used for "</" in the close of a container.
1752 *) ap_add_filter prototype changed to remove the ctx pointer. The
1753 pointer still remains in the filter structure, but it can not be
1754 a part of the ap_add_filter prototype. The reason is that when
1755 the core uses AddFilter to add a filter to the stack it doesn't
1756 know how to allocate the ctx pointer, or even how much memory should
1757 be allocated. The filters will have to be responsible for allocating
1758 the ctx memory when they need it.
1761 *) Add an AddFilter directive. This directive takes a list of filters
1762 that should be activated for the requested resource.
1765 *) apr_snprintf(): Get quad format strings working on OS/390 (and perhaps
1766 some other platforms). [Jeff Trawick]
1768 *) Modify mod_include to be a filter. Currently, it has only been tested
1769 on actual files, but it should work for CGI scripts too.
1772 *) apr_putc(), apr_puts() for Unix: handle buffered files and interrupted
1773 writes. apr_flush() for Unix: handle interrupted writes.
1776 *) NameVirtualHost can now take "*" as an argument instead of
1777 an IP address. This allows you to create a purely name-based
1778 virtual hosting server that does not have any IP addresses in
1779 the configuration file and which ignores the local address
1780 of any connections. PR #5595, PR #4455 [Tony Finch]
1782 *) Fix some compile warnings in mod_mmap_static.c
1783 [Mike Abbott <mja@sgi.com>]
1785 *) Fix chunking problem with CGI scripts. The general problem was that
1786 the CGI modules were adding an EOS bucket and then the core added an
1787 EOS bucket. The chunking filter finalizes the chunked response when it
1788 encounters an EOS bucket. Because two EOS buckets were sent, we
1789 finalized the response twice. The fix is to make sure we only send one
1790 EOS, by utilizing a flag in the request_rec.
1793 *) apr_put_os_file() now sets up the unget byte appropriately on Unix
1794 and Win32. Previously, the first read from an apr_file_t set up via
1795 apr_put_os_file() would return a '\0'. [Jeff Trawick]
1797 *) Mod_cgid now creates a single element bucket brigade, with a pipe
1798 bucket, instead of using BUFF's and ap_r*.
1801 *) APRVARS.in no longer overwrites the EXTRA_LIBS variable.
1802 [Mike Abbott <mja@sgi.com>]
1804 *) Remove ap_bopenf from buff code. This required modifying the file_cache
1805 code to use APR file's directly instead of going through BUFFs.
1808 *) Fix compile break on some platforms for mod_mime_magic.c
1809 [John K. Sterling <sterling@covalent.net>]
1811 *) Fix merging of AddDefaultCharset directive.
1812 PR #5872 (1.3) [Jun Kuriyama <kuriyama@imgsrc.co.jp>]
1814 *) Minor revamp of the rlimit sections of code. We now test
1815 explicitly for setrlimit and getrlimit. Also, unixd_set_rlimit()
1816 is now "available" even if the platform doesn't support
1817 the rlimit family (it's just a noop though). [Jim Jagielski]
1819 *) Migrate the pre-selection of which MPM to use for specific
1820 platforms to hints.m4, which contains (or should contain)
1821 all platform specific "hints". [Jim Jagielski]
1823 *) Remove IOLs from Apache. With filtering, IOLs are no longer necessary
1826 *) Add tables with non-string/binary values to APR.
1829 *) Fix some bad calls to ap_log_rerror() in mod_rewrite.
1832 *) Update PCRE to version 3.2. [Ryan Bloom]
1834 *) Change the way buckets' destroy functions are called so that
1835 they can be more directly used when changing the type of a
1836 bucket in place. [Tony Finch]
1838 *) Add generic support for reference-counting the resources used by
1839 buckets, and alter the HEAP and MMAP buckets to use it. Change
1840 the way buckets are initialised to support changing the type of
1841 buckets in place, and use it when setting aside TRANSIENT buckets.
1842 Change the implementation of TRANSIENT buckets so that it can be
1843 mostly shared with IMMORTAL buckets, which are now implemented.
1846 Changes with Apache 2.0a6
1848 *) Add support to Apache and APR for dsos on OS/390. [Greg Ames]
1850 *) Add a chunking filter to Apache. This brings us one step closer
1851 to removing BUFF. [Ryan Bloom]
1853 *) ap_add_filter now adds filters in a LIFO fashion. The first filter
1854 added to the stack is the last filter to be called. [Ryan Bloom]
1856 *) Apache 2.0 has been completely documented using Scandoc. The
1857 docs can be generated by running 'make docs'. [Ryan Bloom]
1859 *) Add filtered I/O to Apache. This is based on bucket brigades,
1860 Currently the buckets still use BUFF under the covers, but that
1861 should change quickly. The only currently written filter is the
1862 core filter which just calls ap_bwrite. [The Apache Group]
1864 *) APR locks on Unix: Let APR_LOCKALL locks work when APR isn't
1865 built with thread support. [Jeff Trawick]
1867 *) Abort configuration if --with-layout was specified and there's
1868 no layout definition file. [Ken Coar]
1870 *) Add support for '--with-port=n' option to configure. [Ken Coar]
1872 *) Add support for extension methods for the Allow response header
1873 field, and an API routine for accessing r->allowed and the
1874 list of extension methods in a unified manner. [Ken Coar]
1876 *) mod_cern_meta: fix broken file reading loop in scan_meta_file().
1877 [Rob Simonson <simo@us.ibm.com>]
1879 *) Get xlate builds working again. The apr renaming in 2.0a5 broke
1880 APACHE_XLATE builds. [Jeff Trawick]
1882 *) A configuration file parsing problem was fixed. When the
1883 configuration file started with an IfModule/IfDefine container,
1884 only the last statement in the container would be retained.
1887 Changes with Apache 2.0a5
1889 *) Perchild is serving pages after passing them to different child
1890 processes. There are still a lot of bugs, but this does work. I
1891 have made requests against the same installation of Apache, and had
1892 different servers use different user IDs to serve the responses.
1893 This change moves to using socketpair instead of an AF_UNIX socket.
1896 *) Perchild MPM still doesn't work perfectly, but it is serving pages.
1897 It can't seem to pass between child processes yet, but I think we
1898 are closer now than before. This moves us back to using Unix
1899 Domain Sockets. [Ryan Bloom]
1901 *) libapr functions and types renamed with apr_ prefix.
1902 #include "apr_compat.h" for 1.3.x backwards compat
1905 *) Fix problems with APR sockaddr handling on Win32. It didn't always
1906 return the right information on the local socket address.
1907 [Gregory Nicholls <gnicholls@level8.com>]
1909 *) ap_recv() on Win32: Set bytes-read to 0 on error.
1910 [Gregory Nicholls <gnicholls@level8.com>]
1912 *) Add an option to not detach from the controlling terminal without
1913 going into single process mode. This allows for much easier
1914 debugging of the process startup code. [Ryan Bloom]
1916 *) ab: don't use perror() to report the failure of an APR function.
1919 *) Make dexter, mpmt_pthread, and perchild MPMs not destroy the
1920 scoreboard on graceful restarts.
1923 *) Fix segfault/SIGSEGV when running gzip from mod_mime_magic.c.
1924 An invalid ap_proc_t was passed to ap_create_process().
1927 *) Allow modules to register filters. Those filters are still
1928 never called, but this is a step in the right direction.
1929 [Ryan Bloom and Greg Stein]
1931 *) Register the mod_cgid daemon process for cleanup so that it is
1932 killed at termination if it does not die when the parent gets
1933 SIGTERM. This change is to fix occasional problems where the
1934 process stays around. Bugs in similar logic in mod_rewrite and
1935 mod_include were also fixed. [Jeff Trawick]
1937 *) Fix a bug in the time handling. Basically, we were imploding a time
1938 in ap_parseHTTPdate, but it had bogus data in the exploded time format.
1939 Namely, tm_usec and tm_gmtoff were not filled out. ap_implode_time
1940 uses those two fields to adjust the time value. Because of the HTTP
1941 spec, both of those values can be zero'ed out safely. This fixes
1942 the bug correctly. [Ryan Bloom]
1944 *) Fix a couple of place in the Windows code where the wrong error
1945 code was being returned. [Gregory Nicholls <gnicholls@level8.com>]
1947 *) Fix POOL_DEBUG (at least for prefork mpm). [Dean Gaudet]
1949 *) Added the APR_EOL_STR macro for platform dependent differences in
1950 logfiles and other raw text (such as all APR files). Fixes logfiles
1951 not terminated with cr/lf sequences in Win32. [William Rowe]
1953 *) Move all strings functions in APR to src/lib/apr/strings and create
1954 apr_strings.h for the prototypes. [Ryan Bloom]
1956 *) APR lock fixes: when using SysV sems, flock(), or fcntl(), be sure
1957 to repeat the syscall until we stop getting EINTR. I noticed a
1958 related problem at termination (SIGTERM) on FreeBSD when using
1959 fcntl(). Apache 1.3 had these new loops too. Also, make the flock()
1960 implementation work properly with child init. Previously, ap_lock()
1961 was essentially a no-op because all children were using different
1962 locks and thus nobody ever blocked. [Jeff Trawick]
1964 *) The htdocs/ tree has been moved out of the CVS source tree into
1965 a separate area for easier development. This has NO EFFECT on
1966 end-users or Apache installations. [Ken Coar]
1968 *) Integrate the mod_dav module for WebDAV protocol handling. This
1969 adds the dav and dav_fs modules, the SDBM library, and additional
1970 XML handling utilities. [Greg Stein]
1972 *) Clean out obsolete names (from httpd.h) for the HTTP Status Codes
1975 *) Update the lib/expat-lite/ library (bring forward changes from
1976 the Apache 1.3 repository). [Greg Stein]
1978 *) If sizeof(long long) == sizeof(long), then prefer long in APR
1979 configure.in. [Dave Hill <ddhill@zk3.dec.com>]
1981 *) Add ap_sendfile for Tru64 Unix. Also, add an error message for
1982 machines where sendfile is detected, but nobody has written ap_sendfile.
1983 [Dave Hill <ddhill@zk3.dec.com>]
1985 *) Compile fixes in mod_mmap_static. [Victor J. Orlikowski]
1987 *) ab would start up more connections than needed, then quit when the
1988 desired number were finished. Also fixed a logic error involving
1989 ab keepalives. [Victor J. Orlikowski]
1991 *) WinNT: Implement non-blocking pipes with timeouts to communicate
1992 with CGIs. Apache 2.0a4 had non-blocking pipes but without
1993 timeouts (i.e, if a timeout was specified, the pipe reverted to
1994 a full blocking pipe). Now the behaviour is more in line with
1995 Unix non-blocking pipes.
1998 *) WinNT: Implement accept socket reuse. Using mod_file_cache to
1999 cache open file handles along with accept socket reuse enables
2000 Apache 2.0 to serve non-keepalive requests for static files at
2001 3x the rate of Apache 1.3.(e.g, Apache 1.3 will serve 400 rps
2002 and Apache 2.0 will serve almost 1200 rps on my system).
2005 *) Merge mod_mmap_static function into mod_file_cache. mod_file_cache
2006 supports two config directives, mmapfile (same behavious as
2007 mod_mmap_static) and cachefile. Use the cachefile directive
2008 to cache open file handles. This directive only works on systems
2009 that have implemented the ap_sendfile API. cachefile works today
2010 on Windows NT, but has not been tested on any flavors of Unix.
2013 *) Cleanup the configuration. With the last few changes the
2014 configuration process automatically:
2015 inherits information about how to build from APR. Allowing
2016 APR to inform Apache that it should or should not use -ldl
2018 Detects which mod_cgi should be used mod_cgi or mod_cgid,
2019 based on the threading model
2021 Apache calls APR's configure process before finishing it's
2022 configuration processing, allowing for more information flow
2027 *) Change Unix and Win32 ap_setsockopt() so that APR_SO_NONBLOCK
2028 with non-zero argument makes the socket non-blocking. BeOS and
2029 OS/2 already worked this way. [Jeff Trawick]
2031 *) ap_close() now calls ap_flush() for buffered files, so write
2032 operations work a whole lot better on buffered files.
2035 *) Fix error messages issued from MPMs which explain where to change
2036 compiled-in limits (e.g., ThreadsPerChild, MaxClients, StartTreads).
2039 *) ap_create_pipe() now leaves pipes in blocking state. (This helps
2040 reduce the number of syscalls on Unix.) ap_set_pipe_timeout() is
2041 now the way that the blocking state of a pipe is manipulated.
2042 ap_block_pipe() is gone. [Jeff Trawick]
2044 *) Correct the problem where the only local host name that the IP stack
2045 can discover are 'undotted' private names. If no fully qualified
2046 domain name can be identified, the default ServerName will be set to
2047 the machine's IP address string. A warning is always provided if the
2048 ServerName not specified, but assumed. Solves PR6215 [William Rowe]
2050 *) Repair problems with config file processing which caused segfault
2051 at init when virtual hosts were defined and which caused ServerName to
2052 be ignored when there was no valid DNS setup. [Jeff Trawick]
2054 *) Removed pointless ap_is_aborted macro function. [Roy Fielding]
2056 *) Add ap_sendfile implementation for AIX
2057 [Victor J. Orlikowski]
2059 *) Repair C++ compatibility in ap_config.h, apr_file_io.h,
2060 apr_network_io.h, and apr_thread_proc.h.
2061 [Tyler J. Brooks <tylerjbrooks@home.com>, Jeff Trawick]
2063 *) Bring the allocation and pool debugging code back into a working
2064 state. This will need to be tested as so far it's only been used on
2067 *) Change configuration command setup to be properly typesafe when in
2068 maintainer mode. Note that this requires a compiler that can initialise
2069 unions. [Ben Laurie]
2071 *) Turn on buffering for config file reads. Part of this was to
2072 repair buffered I/O support in Unix and implement buffered
2073 ap_fgets() for all platforms. [Brian Havard, Jeff Trawick]
2075 *) Win32: Fix problem where UTC offset was not being set correctly
2076 in the access log. Problem reported on news group by Jerry Baker.
2079 *) Fix segfault when reporting this type of syntax error:
2080 "</container> without matching <container> section", where
2081 container is VirtualHost or Directory or whatever.
2084 *) Prevent the source code for CGIs from being revealed when using
2085 mod_vhost_alias and the CGI directory is under the document root
2086 and a user makes a request like http://www.example.com//cgi-bin/cgi
2087 as reported in <news:960999105.344321@ernani.logica.co.uk>
2090 *) Add support for the new Beos NetwOrking Environment (BONE)
2093 *) xlate: ap_xlate_conv_buffer() now tells the caller when the
2094 final input char is incomplete; ap_bwrite_xlate() now handles
2095 incomplete final input chars. [Jeff Trawick]
2097 *) Yet another update to saferead/halfduplex stuff -- need to ensure
2098 that a bhalfduplex call occurs before logging or else DNS and
2099 such can delay the last packet of the response. [Dean Gaudet]
2101 *) Some syscall reduction in APR on unix -- don't seek when setting
2102 up an mmap; and don't fcntl() more than once per socket.
2105 *) When mod_cgid is started as root, the cgi daemon now switches
2106 to the configured User/Group (like other httpd processes)
2107 instead of continuing as root. [Jeff Trawick]
2109 *) The prefork MPM now uses an APR lock for the accept() mutex.
2110 It has not been getting a lock at all recently. httpd -V now
2111 displays APR's selection of the lock mechanism instead of the
2112 symbols previously respected by prefork. [Jeff Trawick]
2114 *) Change the mmap() feature test to check only for existence.
2115 The previous check required features not used by Apache.
2118 *) Fix a couple of bugs in mod_cgid: The cgi arguments were
2119 sometimes mangled. The len parm to accept() was not
2120 initialized, leading sometimes to an endless loop of failed
2121 accept() calls on OS/390 and anywhere else that failed the call
2122 if the len was negative. Use <sys/un.h> for struct sockaddr_un
2123 instead of declaring it ourselves to fix a compilation problem
2124 on Solaris. [Jeff Trawick]
2126 *) Add Resource limiting code back into Apache 2.0. [Ryan Bloom]
2128 *) Fix zombie process problem with mod_cgi. [Jeff Trawick]
2130 *) Port mod_mmap_static to 2.0. Make it go faster. [Greg Ames]
2132 *) Fix storage overlay when loading dsos. Symptom: Apache dies at
2133 initialization if ALLOC_DEBUG is defined; no known symptom
2134 otherwise. [Jeff Trawick]
2136 *) Fix typo in configure script when checking for mod_so. bash
2137 doesn't seem to have a problem but /bin/sh on Solaris does.
2138 Symptom: "./configure: test: unknown operator =="
2141 *) Rebind the Win32 NT and 9x services control into the MPM.
2142 All console, WinNT SCM and Win9x pseudo-service control code is
2143 now wrapped within the WinNT MPM.
2146 *) Make a copy of getenv("PATH") before storing for later use. Some
2147 getenv() implementations use the same storage for successive calls.
2148 CGIs on OS/390 had a bad PATH due to this. [Jeff Trawick]
2150 *) Server Tokens work in 2.0 again. This also propogates the change
2151 to allow just the product name in the server string using
2155 Changes with Apache 2.0a4
2157 *) EBCDIC: Rearrange calls to ap_checkconv() so that most handlers
2158 won't need to call it. [Greg Ames, Jeff Trawick]
2160 *) Move pre_config hook call to between configuration read and config
2161 tree walk. This allows all modules to implement pre_config hooks
2162 and know that they will be called at an appropriate time.
2165 *) mod_cgi, mod_cgid: Make ScriptLog directive work again.
2168 *) Add pre-config hooks back to all modules.
2171 *) Fix a SIGSEGV in ap_md5digest(), which is used when you have
2172 ContentDigest enabled and we can't/don't mmap the file.
2175 *) We now report the correct line number for syntax errors in config
2176 files. [Ryan Bloom, Greg Stein, Jeff Trawick]
2178 *) Brought mod_auth_digest up to synch with 1.3, fixed ap_time_t-
2179 related bugs, and changed shmem/locking to use apr API. Shared-mem
2180 is currently disabled, however, because of problems with graceful
2181 restarts. [Ronald Tschalär]
2183 *) Fix corruption of IFS variable in --with-module= handling.
2184 Depending on the user's shell or customization thereof, there
2185 would be errors generating ap_config_auto.h later in the configure
2186 procedure. [Jeff Trawick]
2188 *) mod_cgi: Restore logging of stderr from child process when ScriptLog
2189 isn't used (as in 1.3), except that on Unix it is now logged via
2190 ap_log_rerror() instead of by the child having STDERR_FILENO refer
2191 to the error log. [Greg Ames, Jeff Trawick]
2193 *) Add '-D' argument processing for run time configuration defines.
2196 *) Organize http_main.c as independent code, such that no code or
2197 global data is exported from it. WIN32 will dynamically link it
2198 to the server core, so this will prevent mutual dependency.
2201 *) Add separate dynamic linkage tags APR_EXPORT(), APR_EXPORT_NONSTD()
2202 and APR_VAR_EXPORT to correctly resolve apr functions and globals.
2205 *) Add Win9x service execution and Ctrl+C/Ctrl+Break/Shutdown handlers.
2206 [William Rowe, Jan Just Keijser <KEIJSERJJ@logica.com>]
2208 *) Add mod_charset_lite for configuring character set translation.
2211 *) Add '-n' option to htpasswd to make it print its user:pw record
2212 on stdout rather than having to frob a text file. [Ken Coar]
2214 *) Fix saferead. Basically, we flush the output buffer if a read on the
2218 *) APR: Add ap_xlate_get_sb() so that an app can find out whether or not
2219 a conversion is single-byte only. [Jeff Trawick]
2221 *) BEOS: ap_shutdown should return APR_SUCCESS or errno. Note that
2222 the BeOS 5.0 documentation says that shutdown doesn't work yet.
2225 *) Fix some minor errors where pid was being manipulated as an int
2226 instead of the portable pid_t. [Roy Fielding]
2228 *) Fix some error log prints that were printing the pointer to a
2229 structure rather than the pid within the structure.
2230 [Jeff Trawick, Roy Fielding]
2232 *) ab: Fix a command-line processing bug; track bad headers in
2233 err_response; support reading headers up to 2K.
2234 [Ask Bjoern Hansen <ask@valueclick.com>]
2236 *) Fix ap_resolve_env() so that it handles new function added in a prior
2237 alpha (see "Added the capability to do ${ENVVAR} constructs in the
2238 config file.") as well as the constructs used by mod_rewrite.
2239 [Paul Reder <rederpj@raleigh.ibm.com>]
2241 *) Apache 2.0 builds and runs on OS/390. [Jeff Trawick, Greg Ames]
2243 *) Change the EBCDIC support in functions for MD5, SHA1, and base 64 to use
2244 APR to perform translation, instead of accessing the hard-coded tables
2245 in 1.3's ebcdic.c. [Jeff Trawick]
2247 *) Fix some bugs (mostly lost 1.3 code) in ab's command-line processing.
2250 *) Add the ability to hook into the config file reading phase. Basically
2251 if a directive is specified EXEC_ON_READ, then when that directive is
2252 read from the config file, the assocaited function is executed. This
2253 should only be used for those directives that must muck with HOW the
2254 server INTERPRETS the config. This should not be used for directives
2255 that re-order or replace items in the config tree. Those changes should
2256 be made in the pre-config step.
2259 *) Add mod_example to the build system.
2262 *) APR: Add ap_xlate_conv_byte() to convert one char between single-
2263 byte character sets. [Jeff Trawick]
2265 *) Pick up various EBCDIC fixes from 1.3 (from Martin
2266 Kraemer and Oliver Reh originally according to the change log).
2269 *) Fix a couple of problems in RFC1413 support (controlled by the
2270 IdentityCheck directive). Apache did not build the request string
2271 properly and more importantly Apache would loop forever if the
2272 would-be ident server dropped the connection before sending a
2273 properly terminated response. [Jeff Trawick]
2275 *) apxs works in 2.0.
2278 *) Reliable piped logs work in 2.0.
2281 *) Introduce a hash table implementation into APR to be used for
2282 replacing tables and other random data structures in Apache.
2285 *) Add some more error reporting to htpasswd in the case of problems
2286 generating or accessing the temporary file. Also, pass in a
2287 buffer if the implementation knows how to use it (i.e., if L_tmpnam
2288 is defined). [Ken Coar]
2290 *) Configure creates config.nice now containing your configure
2291 options. Syntax: ./config.nice [--more-options]
2294 *) Fix various return code problems in APR on Win32. For most of
2295 these, APR was returning APR_EEXIST instead of GetLastError()/
2296 WSAGetLastError(). [Jeff Trawick]
2298 *) Make piped logs work again in version 2.0
2301 *) Add VPATH support to UNIX build system of Apache and APR.
2304 *) Fix ap_tokenize_to_argv to respect the const arguments that are
2308 *) Fix mm's memcpy/memset macros, pointer arithmetic was broken.
2309 Patch submitted to author.
2312 *) Fix mm configuration on Solaris 8 x86 and OS/390. Don't require
2313 /sbin in PATH on FreeBSD (all submitted to rse previously)
2316 *) Fix building Pthread-based MPMs on OpenBSD
2317 [Sascha Schumann] PR#26
2319 *) Fix ap_readdir() problem on systems where d_name[] field in
2320 struct dirent is declared with only one byte. (This problem only
2321 affected multithreaded builds.) This caused a segfault during
2322 pool cleanup with mod_autoindex on Solaris (Solaris 8 x86, at
2323 least). [Jeff Trawick]
2325 *) Fix some make-portability problems on at least Tru64, Irix
2327 [Sascha Schumann] PR#18, PR#39
2329 *) Add ap_sigwait() to support old-style sigwait() on systems
2330 like OS/390 and UnixWare.
2333 *) Add POSIX-thread flags for more platforms.
2336 *) Fix some minor bugs in ap_strerror(). Teach ap_strerror()
2337 (on Unix, at least) to handle resolver errors. Fix a bug in
2338 the definition of APR_ENOMEM so that ap_strerror() can spit
2339 out the correct error message for it.
2342 Changes with Apache 2.0a3
2344 *) mod_so reports ap_os_dso_error() if ap_dso_load() fails
2347 *) API: *HOOK* macros now have an AP_ prefix
2350 *) Win32: Eliminate redundant calls to initialize winsock.
2351 [Tim Costello <timcostello@ozemail.com.au>]
2353 *) Fix bugs initializing ungetchar for pipes.
2354 [Chia-liang Kao <clkao@CirX.ORG>]
2356 *) The ab program in the src/support directory is now portable using
2360 *) Support directory is being compiled when the server is built
2363 *) The configure option --with-program-name has been added to allow
2364 developers to rename the executable at configure time. This also
2365 changes the name of the config files to match the executable's name.
2368 *) mod_autoindex: Add `IndexOptions +VersionSort', to nicely sort filenames
2369 containing version numbers. [Martin Pool]
2371 *) ap_open(..,APR_OS_DEFAULT,..) uses perms 0666 instead of 0777 on
2372 Unix; access_log and error_log now created with these perms; non-
2373 Unix is unaffected [Jeff Trawick]
2375 *) Finished move of ap_md5 routines to apr_md5. Removed ap_md5.h.
2376 Replaced more magic numbers with MD5_DIGESTSIZE.
2377 [William Rowe, Roy Fielding]
2379 *) Win32: Get mod_auth_digest compiling and added to the Windows
2380 build environment. Not tested and I'd be suprised if it
2381 actually works. [Bill Stoddard]
2383 *) Revamp the Win32 make environment. Makefiles have been removed and
2384 Apache.dsw created to bring together all the pieces. Create new file
2385 os/win32/BaseAddr.ref to define module base addresses (to prevent
2386 dll relocation at start-up).
2387 [William Rowe, Greg Marr, Tim Costello, Bill Stoddard]
2389 *) [EBCDIC] Port Paul Gilmartin's CRLF patch from 1.3. This replaces most
2390 of the \015, \012, and \015\012 constants with macros.
2391 [Greg Ames <gregames@us.ibm.com>]
2393 *) Add ap_xlate_open() et al for translation of text between different
2394 character sets. The initial implementation requires iconv().
2397 *) More FAQs and answers from comp.infosystems.www.servers.unix.
2398 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2400 *) CGI output is being timed out now.
2403 *) Fix the problem with dieing quietly. dupfile now takes a pool which
2404 is used by the new apr file. There is no reason to create a new file
2405 with the same lifetime as the original file.
2408 *) Win32: Attempt to eliminate dll relocation at start-up by specifying
2409 module base addresses. This will help shooting seg faults
2410 in the field. [William Rowe <wrowe@lnd.com>]
2412 *) Update Apache on Windows documentation. Add new document
2413 describing how to compile Apache on Windows.
2414 [William Rowe <wrowe@lnd.com>]
2416 *) ap_set_pipe_timeout(), ap_poll(), and APR_SO_TIMEOUT now take
2417 microseconds instead of seconds. Some storage leaks and other
2418 minor bugs in related code were fixed. [Jeff Trawick]
2420 *) Win32: First cut at getting mod_isapi working under 2.0
2421 [William Rowe <wrowe@lnd.com>]
2423 *) First stab at getting mod_auth_digest working under 2.0
2424 quick change summary:
2425 - moved the random byte generation (ap_generate_random_bytes) into APR
2426 - now uses ap_time_t
2427 - compiles and runs on linux
2429 [Brian Martin <bmartin@penguincomputing.com>]
2431 *) Win32: Move the space stripping of physical service names
2432 fix up from Apache 1.3. #include'ing "ap_mpm.h" fixes up an
2433 unresolved symbol. Add dependency checking to the
2434 CreateService call to ensure TCPIP and AFP (winsock) is started
2436 [William Rowe <wrowe@lnd.com>]
2438 *) Win32: Add code to perform latebinding on functions that may
2439 not exist on all levels of Windows where Apache runs. This
2440 is needed to allow Apache to start-up on Win95/98. All calls
2441 to non portable functions should be protected with
2442 ap_oslevel checks to prevent runtime segfaults.
2443 [William Rowe <wrowe@lnd.com>]
2445 *) Fix fallback default values for SHM_R and SHM_W [Martin Kraemer]
2447 *) Get lingering_close() working again. [Dean Gaudet, Jeff Trawick]
2449 *) Win32: Get non-blocking CGI pipe reads working under Windows NT.
2450 This addresses PR 1623. Still need to address timing out runaway
2451 CGI scripts. [Bill Stoddard]
2453 *) Win32: Make ap_stat Windows 95/98 friendly
2454 [William Rowe <wrowe@lnd.com>]
2456 *) Win32: Fix a bug in ap_get_oslevel which causes GetVersionEx() to
2457 always fail. Need to initialise the dwOSVersionInfoSize member of the
2458 OSVERSIONINFO struct before calling GetVersionEx, so GetVersionEx
2461 The patch also enhances ap_get_oslevel (and the associated enum) to
2462 handle selected service packs for NT4, and adds recognition for
2463 Windows 2000. This is useful, eg. if we can recognise NT4 SP2 then
2464 we can use ReadFileScatter and WriteFileGather in readwrite.c.
2465 [Tim Costello <Tim.Costello@BTFinancialgroup.com>]
2467 *) Get mod_rewrite building and running, and mod_status building for Win NT
2468 [Allan Edwards <ake@raleigh.ibm.com>]
2470 *) Patch to port mod_auth_db to the 2.0 api and also to support
2471 Berlekey DB 3.0. It works for me with both Berkeley DB 3.0.55 and
2472 2.7.7. It should work with version 1 as well but I haven't tested it.
2473 [Brian Martin <bmartin@penguincomputing.com>]
2475 *) Get APR DSO code working under Windows. Includes cross platform
2477 [Tim.Costello@BTFinancialgroup.com]
2479 *) Fix some of the Windows APR time functions.
2482 *) FAQ changes related to tidying up historical documents on the web site.
2483 [Joshua Slive <slive@finance.commerce.ubc.ca>]
2485 *) Move Windows DSO code into APR.
2488 *) Eliminate apr_win.h and apr_winconfig.h (and the ugly #ifdefs they cause).
2489 Now, apr.h and apr_config.h are generated from apr.hw and apr_config.hw
2490 at build time. At this point, the server will not compile on Windows because
2491 of the recent DSO commits. Fixing those next.
2492 [Bill Rowe & Bill Stoddard]
2494 *) Added error checking for file I/O APR routines.
2495 [Jon Travis <jtravis@covalent.net>]
2497 *) APR: Don't use the values of resolver error codes for the
2498 corresponding APR error codes. On Unix and Win32, return the
2499 proper APR error code after a resolver error. [Jeff Trawick]
2501 Changes with Apache 2.0a2
2503 *) Renamed the executable back to httpd on all platforms other
2507 *) Allow BeOS to survive restarts, log properly and a few
2508 small things it had problems with due to the way it setup
2509 users and groups. [David Reid]
2511 *) Get mod_rewrite working with APR locks
2512 [Paul Reder <rederpj@raleigh.ibm.com>]
2514 *) Actually remove the sempahore when the lock cleanup routine
2515 is called on BeOS. [David Reid]
2517 *) Clear hook registrations between reads of the config file.
2518 When DSOs are unloaded and re-loaded the old hook pointers may
2519 no longer be valid. This fix eliminates potential segfaults.
2520 [Allan Edwards <ake@raleigh.ibm.com>]
2522 *) Fix a problem with Sigfunc not being defined or bypassed
2523 if sigaction() wasn't found. [Jim Jagielski]
2525 *) Fix the locking mechanism on BSD variants. They now use fcntl
2526 locks. This allows the server to start and serve pages.
2529 *) First cut at getting the Win32 installer to work
2530 [William Rowe <wrowe@lnd.com>]
2532 *) Get htpasswd compiling under Windows
2533 [William Rowe <wrowe@lnd.com>]
2535 *) Change the log message for a bind() failure to show the
2536 interface and port number. [Jeff Trawick]
2538 *) Import the documentation from 1.3.12 and bring parts of it
2539 up-to-date with respect to the changes that have occurred
2543 *) BeOS MPM updated. CGI bug on BeOS fixed. IP addresses
2544 now logged correctly on BeOS.
2547 *) Create one makefile for all Win32 distributions (NT/2000/95/98).
2548 Makefile.win includes the same user interface as the old
2550 [William Rowe <wrowe@lnd.com>, Jeff Trawick <trawick@us.ibm.com>]
2552 *) Win32 exec now uses COMSPEC environment string for command
2553 shell path resolution.
2554 [William Rowe <wrowe@lnd.com>] PR#3715
2556 *) Win32: ap_connect() was not returning correct error condition
2558 [Allen Prescott <allen@clanprescott.com>]
2560 *) Win32: ap_open() was broken on Win9x because an NT-specific
2561 flag was passed to CreateFile. ap_puts() added an unnecessary
2563 [Jeff Trawick <trawick@us.ibm.com>]
2565 *) Put in Korean and Norwegian index.html pages (2.0 and 1.3)
2566 which where donated by Lee Kuk Hyun and Lorant Czaran. 'Fixed'
2567 confusing ee/et name and made all extensions language/dialect
2568 rather than country reflecting. Changed example files to
2569 explicit reflect the ISO charset and added a few common
2570 ones to the example config [dirkx]
2572 *) Extend external module capability. To use this, you call
2573 configure with --with-module=path/to/mod1,path/to/mod2,etc.
2576 *) Backported the various "default charset" fixes from 1.3.12,
2577 including the AddDefaultCharset directive. [Jim Jagielski]
2579 *) Added the capability to do ${ENVVAR} constructs in the
2580 config file. E.g. 'ServerAdmin ${POSTMASTER}'. As commited
2581 it does this on a line by line basis; i.e. if the envvar
2582 expands to something with spaces you have to protect it
2583 by adding quotes around it (Unless of course you expect it
2584 to contains more than one argument. Alternatively you
2585 can compile it on a per token basis; which is what people
2586 usually expect by setting RESOLVE_ENV_PER_TOKEN. But this
2587 hampers fancier hacks.
2588 [Dirk-Willem van Gulik]
2590 *) Changed the 'ErrorDocument' syntax in that it NO longer
2591 supports the asymetric
2593 ErrorDocument 301 "Some message
2595 Note the opening " quote, without a closing quote. It now
2596 has either the following syntaxes
2598 ErrorDocument XXX /local/uri
2599 ErrorDocument XXX http://valid/url
2600 ErrorDocument XXX "Some Message"
2602 The recognition heuristic is: if it has a space it
2603 is a message. If it has no spaces and starts with a /
2604 or is a valid URL then treat it that way. Otherwise it
2605 is assumed to be a message.
2607 This breaks backward compatibility but makes live a hell
2608 of a lot easier for GUI's and config file parsers.
2609 [Dirk-Willem van Gulik]
2611 *) Changed 'CacheNegotiatedDocs' from its present/not-present
2612 syntax into a 'on' or 'off' syntax. As it currently is the
2613 only non nesting token which uses NO_ARGS and thus is an
2614 absolute pain for any config interface automation. This
2615 breaks backward compatibility. [Dirk-Willem van Gulik]
2617 *) Add ability to add external modules to the build process. This is
2618 done with --with-module=/path/to/module. Modules can only be added
2619 as static modules at this point.
2622 Changes with Apache 2.0a1
2624 *) Fix FreeBSD 3.3 core dump.
2625 Basically, ap_initialize() needs to get called before
2626 create_process(), since create_process() passes op_on structure
2627 to semop() to get a lock, but op_on isn't initialized until
2628 ap_initialize() calls setup_lock(). Here is a slight
2629 rearrangement to main() which calls ap_initialize() earlier...
2630 [Jeff Trawick <trawick@us.ibm.com>]
2632 *) Enable Apache to use sendfile/TransmitFile API
2633 [Bill Stoddard, David Reid, Paul Reder]
2635 *) Re-Implement Win32 APR network I/O APIs and most of the file I/O
2639 *) Make file I/O and network I/O writev/sendv APIs consistent.
2640 Eliminate use of ap_iovec_t and use Posix struct iovec.
2641 Use seperate variable on ap_writev to set the number of iovecs
2642 passed in and number of bytes written.
2645 *) Adapt file iol to use APR functions. Replaced ap_open_file()
2646 with ap_create_file_iol(). ap_create_file_iol() requires that
2647 the file be opened prior to the call using ap_open().
2650 *) Port mod_include and mod_cgi to 2.0
2651 [Paul Reder, Bill Stoddard]
2653 *) ap_send{,v}, ap_recv, ap_sendfile API clarification --
2654 bytes_read/bytes_written is always valid (never -1). Plus
2655 some fixes to buff.c to correct problems introduced by the
2656 errno => ap_status_t changes a while back. Plus a fix to
2657 chunked encoding introduced right at the beginning of 2.0.
2660 *) Revamped UNIX build system to use autoconf and libtool.
2661 [Manoj Kasichainula, Sascha Schumann]
2663 *) port mod_rewrite to 2.0. [Paul J. Reder <rederpj@raleigh.ibm.com>]
2665 *) More rigorous checking of Host: headers to fix security problems
2666 with mass name-based virtual hosting (whether using mod_rewrite
2667 or mod_vhost_alias).
2668 [Ben Hyde, Tony Finch]
2670 *) Add back support for UseCanonicalName in <Directory> containers.
2671 [Manoj Kasichainula]
2673 *) Added APLOG_STARTUP log type. This allows us to write an error
2674 message without any of the date and time information. As a part
2675 of this change, I also removed all of the calls to fprintf(stderr
2676 and replaced them with calls to ap_log_error using APLOG_STARTUP
2677 writing to stderr is no longer portable, because we don't direct
2678 stderr to the error log on all platforms.
2681 *) Convert error logging functions to take errno as an argument.
2682 This makes our error logs more portable, because some Windows API's
2683 don't set errno. This change allows us to still output a valid
2684 message on all of our platforms.
2687 *) mod_mime_magic runs in 2.0-dev now.
2688 [Paul Reder <rederpj@raleigh.ibm.com>]
2690 *) sendfile has been added to APR.
2691 [John Zedlewski <zedlwski@Princeton.EDU>]
2693 *) buff.c has been converted to no longer use errno.
2694 [Manoj Kasichainula]
2696 *) mod_speling runs in 2.0-dev now: a bug in readdir_r handling and
2697 interface adaption to APR functions did it. [Martin Kraemer]
2699 *) Support DSOs properly on 32-bit HP-UX 11.0
2700 [Dilip Khandekar <dilip@cup.hp.com>]
2702 *) Updated MM in APR source tree from version 1.0.8 to 1.0.11
2703 [Ralf S. Engelschall]
2705 *) Cleaned APR build environment integration and bootstrap APR
2706 automatically for developers from src/Configure.
2707 [Ralf S. Engelschall]
2709 *) Fixed building of src/support/htpasswd.c
2710 [Ralf S. Engelschall]
2712 *) When generating the Location: header, mod_speling forgot
2713 to escape the spelling-fixed uri. (Forw-Port from 1.3)
2716 *) Moved mod_auth_digest.c from experimental to standard. [Roy Fielding]
2718 *) Change all pools to APR contexts. This is the first step to
2719 incorporating APR into Apache. [Ryan Bloom]
2721 *) Move "handler not found" warning message to below the check
2722 for a wildcard handler. [Dirk <dirkm@teleport.com>, Roy Fielding]
2723 PR#2584, PR#2751, PR#3349, PR#3436, PR#3548, PR#4384, PR#4795, PR#4807
2725 *) Support line-continuation feature in config.option file and
2726 allow the loading of multiple option sections at once via
2727 ``--with-option=<section1>,<section2>,...''
2728 [Ralf S. Engelschall]
2730 *) Rebuilt CVS repository with Apache 1.3.9 as basis. [Roy Fielding]
2732 Changes with Apache MPM
2734 *) Use asynchronous AcceptEx() and a completion port to accept and
2735 dispatch connections to threads in Windows NT/2000.
2738 *) Implement WINNT Win32 MPM from original Win32 code in http_main.c
2741 *) Implement the APACI --with-option facility
2742 (per default used the config.option file).
2743 [Ralf S. Engelschall]
2745 *) MPM BEOS port. [David Reid <abb37@dial.pipex.com>]
2747 *) Start to implement module-defined hooks that are a) fast and b) typesafe.
2748 Replace pre_connection module call with a register_hook call and
2749 implement pre_connection as a hook. The intent is that these hooks will
2750 be extended to allow Apache to be multi-protocol, and also to allow the
2751 calling order to be specified on a per-hook/per-module basis.
2754 *) Implement mpm_* methods as "modules". Each method gets its own
2755 subdir in src/modules (eg: src/modules/prefork). Selection
2756 of method uses Rule MPM_METHOD. [Jim Jagielski]
2758 *) Port the hybrid server from the apache-apr repository as
2759 mpm_mpmt_pthread. [Manoj Kasichainula]
2761 *) os/unix/unixd.[ch]: detach, setuid, setgid, stuff which will be common
2762 amongst the unix MPMs.
2764 *) mpm_prefork: throw away all the alarm/timeout crud; and clean up the
2765 signal handling for the new world order. [Dean Gaudet]
2767 *) Crude ap_thread_mutex abstraction so that we get the pthread stuff out
2768 of alloc.c for now. [Dean Gaudet]
2770 *) Handle partial large writes correctly. [Ben Laurie]
2772 *) Eliminate conn_rec's pointer to server. All it knows is the base server
2773 based on IP/port. [Ben Laurie]
2775 *) Port a bunch of modules to the new module structure.
2776 ["Michael H. Voase" <mvoase@midcoast.com.au>]
2778 *) I/O layering and BUFF revamp. See docs/buff.txt. [Dean Gaudet]
2780 *) Basic restructuring to introduce the MPM concept; includes various
2781 changes to the module API... better described by
2782 docs/initial_blurb.txt. [Dean Gaudet]
2784 Changes with Apache pthreads
2786 *) New buff option added: BO_TIMEOUT. It describes the timeout for
2787 buff operations (generally over a network).
2788 [Dean Gaudet, Ryan Bloom, Manoj Kasichainula]
2790 *) Created http_accept abstraction. Added 4 new functions (not exported):
2791 init_accept(), begin_accepting_requests(), get_request(),
2792 stop_accepting_requests() [Bill Stoddard]
2794 *) Fix to ap_rprintf call that allows mod_info to work properly.
2795 [James Morris <jmorris@intercode.com.au>]
2797 *) user and ap_auth_type fields were moved from connection_rec to
2798 request_rec. [Ryan Bloom]
2800 *) Removed the ap_block_alarms and ap_unblock_alarm calls. These aren't
2801 needed in a threaded server.
2803 *) Initial pthread implementation from from Dean's apache-nspr code.
2804 [Bill Stoddard, Ryan Bloom]
2807 Changes with Apache 1.3.9
2809 *) Remove bogus error message when a redirect doesn't set Location.
2810 Instead, use an empty string to avoid coredump if the error message
2811 was supposed to include a location. [Roy Fielding]
2813 *) Don't allow configure to include mod_auth_digest unless it is
2814 explicitly requested, even if the user asked for all modules.
2817 *) Translate module names to dll names for OS/2 so that they are no more
2818 than 8 characters long and have an extension of "dll" instead of "so".
2821 *) Print out pointer to Rule DEV_RANDOM when truerand lib not found.
2822 Fix test-compile check to check for randbyte instead of trand32.
2823 Use ap_base64encode_binary/decode instead of copy in mod_auth_digest.c
2824 and tweak to make Amaya happier. [Ronald Tschalär]
2826 *) Ensure that the installed expat include files are world readable,
2827 just like the other header files. [Martin Kraemer]
2829 *) Fixed generated AddModule adjustments in APACI's `configure' script
2830 in order to allow (new) modules like mod_vhost_alias to be handled
2831 correctly (which was touched by the adjustments for mod_alias).
2832 [Ralf S. Engelschall]
2834 *) For binary builds, add -R flag to apachectl to work around the lack of
2835 an absolute path to the ./libexec directory where the libhttp.ep file
2836 is needed for SHARED_CORE architectures. [Randy Terbush]
2838 *) WIN32: Create the CGI script process as DETACHED. This may solve the
2839 problem observed by some Win95/98 users where they get CGI script
2840 output sent to the console. [Bill Stoddard]
2842 *) Fix (re)naming in the uuencode/decode section. The ap/ap_
2843 routines are now called ap_base64* and are 'plain' (i.e., no
2844 pool access or anything clever). Inside util.c the routines acting
2845 like pstrdup are called ap_pbase64encode() and ap_pbase64decode().
2846 The oddly named ap_uuencode(), ap_uudecode() are kept around for
2847 now but deprecated. [dirkx]
2849 *) Clean up the base64 and SHA1 additions and make sure they are
2850 represented in the ApacheCore.def, ApacheCoreOS2.def, and httpd.exp
2851 files. [Roy Fielding]
2853 *) WIN32: Migrate to InstallShield 5.5 and provide a bit more error
2854 checking. Allow compiling on VS 6.0. [Randy Terbush]
2856 *) Fixed assumption of absolute paths in binbuild.sh. [Tony Finch]
2858 *) Use TestCompile to search for the truerand library (rather than blindly
2859 assuming its existence). If it is not found, complain (but do not
2860 exit - yet). [Martin Kraemer]
2862 *) We forgot to add the new exported function names to
2863 src/support/httpd.exp. [Bill Stoddard, Randy Terbush]
2865 *) Add description of -T command-line option to usage().
2866 [Ralf S. Engelschall]
2868 *) For "some" platforms (notably, EBCDIC based ones), libos needs to be
2869 searched only AFTER libap has been searched, because libap needs
2870 some symbols from libos. [Martin Kraemer]
2872 *) Fix conflict with original mod_digest related to the symbol of the
2873 module dispatch list (which has to be unique for DSO and follow the
2874 usual conventions for the installation procedure).
2875 [Ralf S. Engelschall]
2877 *) Add a dbm-library check for the "usual places" (-ldbm, -lndbm, -ldb)
2878 for other platforms as well. [Martin Kraemer]
2880 *) Make ap_sha1.c compile for EBCDIC platforms: replace remaining LONG
2881 types by AP_LONG and replace reference to renamed variable 'ubuf'
2882 by 'buffer'. [Martin Kraemer]
2884 Changes with Apache 1.3.8 [not released]
2886 *) Flush the output buffer immediately after sending an error or redirect
2887 response, since the result may be needed by the client to abort a
2888 long data transfer or restart a series of pipelined requests.
2889 [Tom Vaughan <tvaughan@aventail.com>, Roy Fielding]
2891 *) PORT: Improved compilation and DSO support on Sequent DYNIX/ptx.
2892 [Ian Turner <iant@sequent.com>] PR#4735
2894 *) Local struct mmap in http_core.c conflicted with system structure
2895 name on DYNIX -- changed to mmap_rec. [Roy Fielding] PR#4735
2897 *) Added updated mod_digest as modules/experimental/mod_auth_digest.
2898 [Ronald Tschalär <ronald@innovation.ch>]
2900 *) Fix a memory leak where the module counts were getting messed
2901 up across restarts. [David Harris <dharris@drh.net>]
2903 *) CIDR addresses such as a.b.c.d/24 where d != 0 weren't handled
2904 properly in mod_access.
2905 ["Paul J. Reder" <rederpj@raleigh.ibm.com>] PR#4770
2907 *) RewriteLock/RewriteMap didn't work properly with virtual hosts.
2908 [Dmitry Khrustalev <dima@bog.msu.su>] PR#3874
2910 *) PORT: Support for compaq/tandem/com.
2911 [Michael Ottati <michael.ottati@compaq.com>, dirkx]
2913 *) Added SHA1 password encryption support to easy migration from
2914 Netscape servers. See support/SHA1 for more information.
2915 Caused the separation of ap_md5.c into md5, sha1 and a general
2916 ap_checkpass.c with just a validate_passwd routine. Added a
2917 couple of flags to support/htpasswd. Some reuse of the to64()
2918 function; hence renamed to ap_to64().
2919 [Dirk-Willem van Gulik, Clinton Wong <clintdw@netcom.com>]
2921 *) Change for EBCDIC platforms (TPF and BS2000) to correctly deal
2922 with ASCII/EBCDIC conversions in "ident" query.
2923 [David McCreedy <McCreedy@us.ibm.com>]
2925 *) Get rid of redefinition warning on MAC_OS_X_SERVER platform.
2926 Change "Power Macintosh" to Power* so if uname prints "Power Book"
2927 we're still happy on Rhapsody platforms. [Wilfredo Sanchez]
2929 *) Fix SIGSEGV on some systems because the Vary fix below included
2930 a call to table_do with a variable argument list that was not
2931 NULL terminated. Replaced with better implementation. [Roy Fielding]
2933 Changes with Apache 1.3.7 [not released]
2935 *) The "Vary" response header field is now sanitised right before
2936 the header is sent back to the client. Multiple "Vary" fields
2937 are combined, and duplicate tokens (e.g., "Vary: host, host" or
2938 "Vary: host, negotiate, host, accept-language") are reduced to
2939 single instances. This is a better solution than the force-no-vary
2940 one (which is still valid for clients that can't cope with Vary
2941 at all). PR#3118 [Dean Gaudet, Roy Fielding, Ken Coar]
2943 *) Portability changes for BeOS. [David Reid abb37@dial.pipex.com]
2945 *) Link DSO's with "gcc -shared" instead of "ld -Bshareable" at
2946 least on Linux and FreeBSD for now.
2949 *) Win32: More apache -k restart work. Restarts are now honored
2950 immediately and connections in the listen queue are -not- lost.
2951 This is made possible by the use of the WSADuplicateSocket()
2952 call. The listeners are opened in the parent, duplicated, then
2953 the duplicates are passed to the child. The original listen sockets
2954 are not closed by the parent across a restart, thus the listen queue
2956 [Bill Stoddard <stoddard@raleigh.ibm.com>]
2958 *) Fix handling of case when a client has sent "Expect: 100-continue"
2959 and we are going to respond with an error, but get stuck waiting to
2960 discard the body in the pointless hope of preserving the connection.
2961 [Roy Fielding, Joe Orton <jeo101@york.ac.uk>] PR#4499, PR#3806
2963 *) Fix 'configure' to work correctly with SysV-based versions of
2964 'tr' (consistent with Configure's use as well). [Jim Jagielski]
2966 *) apxs: Add "-S var=val" option which allows for override of CFG_*
2967 built-in values. Add "-e" option which works like -i but doesn't
2968 install the DSO; useful for editing httpd.conf with apxs. Fix
2969 editing code so that multiple invocations of apxs -a will not
2970 create duplicate LoadModule/AddModule entries; apxs can now be
2971 used to re- enable/disable a module. [Wilfredo Sanchez]
2973 *) Win32: Update the server to use Winsock 2. Specifically, link with
2974 ws2_32.lib rather than wsock32.lib. This gives us access to
2975 WSADuplcateSocket() in addition to some other enhanced comm APIs.
2976 Win 95 users may need to update their TCP/IP stack to pick up
2977 Winsock 2. (See http://www.microsoft.com/windows95/downloads/)
2978 [Bill Stoddard stoddard@raleigh.ibm.com]
2980 *) Win32: Redirect CGI script stderr (script debug info) into the
2981 error.log when CGI scripts fail. This makes Apache on Win32
2982 behave more like Unix.
2983 [Bill Stoddard stoddard@raleigh.ibm.com]

2998 *) Add the new mass-vhost module (mod_vhost_alias.c) developed and
2999 used by Demon Internet, Ltd. [Tony Finch <fanf@demon.net>]
3001 *) Better GCC detection for DSO flags under Solaris 2 where the `cc'
3002 command potentially _is_ GCC. [Ralf S. Engelschall]
3004 *) Fix apxs build issues on AIX
3005 [Rasmus Lerdorf <rasmus@raleigh.ibm.com>]
3007 *) DocumentRoot Checking: Under previous versions, when Apache
3008 first started up, it used to do a stat of each DocumentRoot to
3009 see if it existed and was a directory. If not, then an error
3010 message was printed. THIS HAS BEEN DISABLED. If DocumentRoot
3011 does not exist, you will get error messages in error_log. If
3012 the '-t' command line option is used (to check the configuration)
3013 the check of DocumentRoot IS performed. An additional command
3014 line option, '-T', has been added if you want to avoid the
3015 DocumentRoot check even when checking the configuration.
3018 *) Win32: The query switch "apache -S" didn't exit after showing the
3019 vhost settings. That was inconsistent with the other query functions.
3020 [Bill Stoddard - Fixed by Martin on Unix in 1.3.4]
3022 *) Win32: Changed behaviour of apache -k restart.
3023 Previously, the server would drain all connections in the stack's
3024 listen queue before honoring the restart. On a busy server, this
3025 could take hours. Now, a restart is honored almost immediately.
3026 All connections in Apache's queues are handled but connections in
3027 the stack's listen queue are discarded. Restart triggered by
3028 MaxRequestPerChild is unchanged.
3029 [Bill Stoddard <stoddard@raleigh.ibm.com>]
3031 *) Win32: Eliminated unnecessary call to wait_for_multiple_objects in
3032 the accept loop. Good for a 5% performance boost. Cleaned up
3033 parent/child process management code.

3046 *) Allow .module files to specify libraries with Lib:.
3049 *) Allow SetEnvIf[NoCase] to test environment variables as well
3050 as header fields and request attributes. [Ken Coar]
3052 *) Fix mod_autoindex's handling of ScanHTMLTitles when file
3053 content-types are "text/html;parameters". PR#4524 [Ken Coar]
3055 *) Remove "mxb" support from mod_negotiation -- it was a draft feature
3056 never accepted into any standard, and it opens up certain DoS
3057 attacks. [Koen Holtman <Koen.Holtman@cern.ch>]
3059 *) TestCompile updated. We can now run programs and output the
3060 results during the Configure process. [ Jim Jagielski]
3062 *) The source is now quad (long long) aware as needed. Specifically,
3063 the Configure process determines the correct size of off_t and
3064 *void. When the OS/platform/compiler supports quads, ap_snprintf()
3065 provides for the 'q' format qualifier (if quads are not available,
3066 'q' is silently "demoted" to long). [Jim Jagielski]
3068 *) When the username or password fed to htpasswd is too long, include the
3069 size limit in the error message. Also report illegal characters
3070 (currently only ':') in the username. Add the size restrictions
3071 to the man page. [Ken Coar]
3073 *) Fixed the configure --without-support option so it doesn't result in
3074 an infinite loop. [Marc Slemko]
3076 *) Piped error logs could cause a segfault if an error occured
3077 during configuration after a restart.
3078 [Aidan Cully <aidan@panix.com>] PR#4456
3080 *) If a "Location" field was stored in r->err_headers_out rather
3081 than r->headers_out, redirect processing wouldn't find it and
3082 the server would core dump on ap_escape_html(NULL). Check both
3083 tables and raise HTTP_INTERNAL_SERVER_ERROR with a log message
3084 if Location isn't set. [Doug MacEachern, Ken Coar]
3086 *) Add RULE_EXPAT, the src/lib/ directory structure, and a modified copy
3087 of the Expat 1.0.2 distribution. [Greg Stein]
3089 *) Replace regexec() calls with calls to a new API stub function
3090 ap_regexec(). This solves problems with DSO modules which use the regex
3091 library. [Jens-Uwe Mager <jum@helios.de>, Ralf S. Engelschall]
3093 *) Add 'Request_Protocol' special keyword to mod_setenvif so that
3094 environment variables can be set according to the protocol version
3095 (e.g., HTTP/0.9 or HTTP/1.1) of the request. [Ken Coar]
3097 *) Add DSO support for OpenStep (Mach 4.2) platform.

3112 *) Support for server-parsed and multiview-determined ReadmeName and
3113 HeaderName files in mod_autoindex. Removed the restriction on
3114 "/"s in ReadmeName and HeaderName directives since the *sub_req*
3115 routines will deal with the access issues. (It's now possible to
3116 have {site|group|project|customer|...} wide readmes and headers.)

3128 [Salvador Ortiz Garcia <sog@msg.com.mx>]
3130 *) Mac OS and Mac OS X Server now use the appropriate custom layout
3131 by default when building with APACI; allow for platform-specific
3132 variable defaults in configure. [Wilfredo Sanchez]
3134 *) Do setgid() before initgroups() in http_main; some platforms
3135 zap the grouplist when setgid() is called. This was fixed in
3136 suexec earlier, but the main httpd code missed the change.

3151 *) Fix minor but annoying bug with the test for Configuration.tmpl
3152 being newer than Configuration so that it is less likely to fail
3153 when using APACI and shadow sources. [Wilfredo Sanchez]
3155 *) PORT: Add initial support for Mac OS (versions 10.0 and
3156 greater). Use Mac OS X Server layout for now. Clean up dyld code
3157 in unix/os.c, and don't install the dyld error handlers, which
3158 are no longer needed in Mac OS. [Wilfredo Sanchez]
3160 *) Rename Rhapsody layout to "Mac OS X Server". Change install
3161 locations to appropriate ones for user-built (as opposed to
3162 system) installs. [Wilfredo Sanchez]
3164 *) Modify mod_autoindex's handling of AddDescription so that the
3165 behaviour matches the documentation. [Ken Coar] PR#1898, 3072.
3167 *) Add functionality to the install-bindist.sh script created by
3168 binbuild.sh to use tar when copying distribution files to the
3169 serverroot. This allows upgrading an existing installation
3170 without nesting the new distribution in the old.
3172 install-bindist.sh now detects the local perl5 path to install
3173 apxs and dbmmanage with proper path to perl interpreter.
3175 Add an install-binsupport target which copies the source files
3176 for apxs and dbmmanage to bindist to allow these scripts to
3177 be properly installed relative to the destination serverroot.

3344 *) OS/2: Rework CGI handling to use spawn*() instead of fork/exec, achieving
3345 a roughly 5 fold speed up. [Brian Havard]
3347 *) proxy ftp: instead of using the hardwired string "text/plain" as
3348 a fallback type for files served by the ftp proxy, use the
3349 ap_default_type() function to determine the configured type.
3350 This allows for special configurations like
3351 <Directory proxy:ftp://some.host>
3352 DefaultType gargle/blurb
3354 Additionally, add the Content-Encoding: header to FTP proxy replies
3355 when the encoding is defined (by the AddEncoding directive).
3356 Because it was missing, it was almost impossible to browse compressed
3357 files using the FTP proxy (works now perfectly in Communicator).
3358 The ftp proxy now also returns the Date: and Server: header lines (if not
3359 much else... This code is "somewhat" broken) like normal requests do.
3362 *) Be more smart in APACI's configure script when determining the UID/GID

3439 for 8-bit safeness. [Dean Gaudet]
3441 *) PORT: Use -fPIC instead of -fpic on Solaris and SunOS for compiling DSOs
3442 because SPARCs have a small machine-specific maximum size for the Global

3444 third-party modules with Apache. [Peter Urban <Peter.Urban@epfl.ch>] PR#3977
3446 *) Move the directive `ExtendedStatus' in httpd.conf-dist-win _after_ the

3479 *) In configure, do not append the target name to the directory path if
3480 the path already contains "apache". [Ralf S. Engelschall]
3482 *) SIGPIPE is now ignored by the server core. The request write routines
3483 (ap_rputc, ap_rputs, ap_rvputs, ap_rwrite, ap_rprintf, ap_rflush) now
3484 correctly check for output errors and mark the connection as aborted.
3485 Replaced many direct (unchecked) calls to ap_b* routines with the
3486 analogous ap_r* calls. [Roy Fielding]
3488 *) Enhanced mod_rewrite's mapfile handling: The in-core cache for text and
3489 DBM format mapfiles now uses a 4-way hash table with LRU functionality.
3490 Furthermore map lookups for non-existent keys are now cached as well.
3491 Additionally "txt" maps are now parsed with simple string functions
3492 instead of using ap_pregcomp(). As a side effect a bug that prevented
3493 the usage of keys containing the "," character was fixed.
3494 The changes drastically improve the performance when large rewrite maps

3498 *) Added ap_sub_req_method_uri() for doing a subrequest with a method
3499 other than GET, and const'd the definition of method in request_rec.
3502 *) Use proper pid_t type for saving PIDs in alloc.c. [John Bley]
3504 *) Replaced use of WIN32 define with HAVE_DRIVE_LETTERS to indicate
3505 when the OS allows a DOS drive letter within pathnames. [Brian Havard]
3507 *) Add %V to mod_log_config, this logs the hostname according to the
3508 UseCanonicalName setting (this is the pre-1.3.4 behaviour of
3509 %v). Useful for mass vhosting. [Tony Finch <dot@dotat.at>]
3511 *) Add support for \n and \t to mod_log_config, can be used to produce
3512 more reliable logs with multiline entries. [Tony Finch <dot@dotat.at>]
3514 *) Fixed a few compiler nits. [John Bley <jbb6@acpub.duke.edu>]

3544 *) Allow apache acting as a proxy server to relay the real
3545 reason of a failure to a client rather than the "internal
3546 server error" it does currently. The general exposure mechanism
3547 can be triggered by any module by setting the "verbose-error-to"
3548 note to "*"; this allows more than just proxy errors to be exposed.

3557 *) Tweak modules Makefile generated by Configure so that it handles
3558 the test case of no modules being selected. [chaz@reliant.com]
3560 *) Added a <LimitExcept method ...> sectioning directive that allows
3561 the user to assign authentication control to any HTTP method that
3562 is *not* given in the argument list; i.e., the logical negation
3563 of the <Limit> directive. This is particularly useful for controlling
3564 access on methods unknown to the Apache core, but perhaps known by
3565 some module or CGI script. [Roy Fielding, Tony Finch]

3584 *) Added ap_size_list_item(), ap_get_list_item(), and ap_find_list_item()
3585 to util.c for parsing an HTTP header field value to extract the next
3586 list item, taking into account the possible presence of nested comments,
3587 quoted-pairs, and quoted-strings. ap_get_list_item() also removes
3588 insignificant whitespace and lowercases non-quoted tokens.
3589 [Roy Fielding] PR#2065
3591 *) proxy: The various calls to ap_proxyerror() can return HTTP/1.1 status
3592 code different from 500. This allows the proxy to, e.g., return

3599 *) Do not round the TCN quality calculation to 5 decimal places,
3600 unlike RFC 2296, because the calculation might need 12 decimal places
3601 to get the right result. [Roy Fielding]
3603 *) Remove unused code to disable transparent negotiation when
3604 negotiating on encoding only, as we now handle encoding too
3605 (though this is nonstandard for TCN), remove charset=ISO-8859-1
3606 fiddle from the fiddle-averse RVSA comparison, and fix bugs in

3610 file is negotiable and no acceptable variant can be found.

3613 *) Win32: Add new config directive, ScriptInterpreterSource, to enable
3614 searching the Win32 registry for script interpreters.
3617 *) Win32: The compiled-in default filename for the error log is now
3618 error.log, which matches the default in the distributed httpd.conf.
3621 *) Win32: Any error messages from -i or -u command line options are now
3622 displayed on the console output rather than sent to the error log.
3623 Also the "Running Apache..." message is not output unless Apache is
3624 going to serve requests. [Paul Sutton]
3626 *) Rework the MD5 authentication scheme to use FreeBSD's algorithm,
3627 and use a private significator ('$apr1$') to mark passwords as
3628 being smashed with our own algorithm. Also abstract the password
3629 checking into a new ap_validate_password() routine. [Ken Coar]
3631 *) Win32: The filename validity checker now allows "COM" but refuses
3632 access to "COM1" through "COM4". This allows filenames such
3633 as "com.name" to be served. [Paul Sutton] PR#3769.

3662 [Jim Jagielski] PR#3671
3664 *) A consistent and conservative style for all shell scripts has been
3665 implemented. Basically, all shell string tests use the traditional
3666 hack of 'if [ "x$var" != "x" ]' or 'if [ "x$var" = "xstring" ]'
3667 to protect against bare null variable strings (ie: wrapping both
3668 sides with double quotes and prepending 'x'). 'x' was chosen
3669 because it's more universal and hopefully easier for old shell
3670 prgrammers, as well as being easier to search for in 'vi' (/x\$) :)
3673 *) The status module now prints out both the main server generation as
3674 well as the generation of each process. Also, the vhost info is
3675 printed with '?notable'. [Jim Jagielski]
3677 *) Move src/main/md5c.c to src/ap/ap_md5c.c; it's httpd-neutral
3678 and this makes its functions available to things in src/support.
3681 Changes with Apache 1.3.4
3683 *) Renamed macros status_drops_connection to ap_status_drops_connection
3684 and vestigial scan_script_header to ap_scan_script_header_err,
3685 mostly for aesthetic reasons. [Roy Fielding]
3687 *) The query switch "httpd -S" didn't exit after showing the
3688 vhost settings. That was inconsistent with the other query functions.
3691 *) Moved the MODULE_MAGIC_COOKIE from before the versions and
3692 filename to the end of the STANDARD_MODULE_STUFF. Its
3693 presence at the beginning prevented reporting of the filename
3694 for modules compiled before 1 January 1999. [Ken Coar]
3696 *) SECURITY: ap_os_is_filename_valid() has been added to Win32
3697 to detect and prevent access to special DOS device file names.
3698 [Paul Sutton, Ken Parzygnat]
3700 *) WIN32: Created new makefiles Makefile_win32.txt (normal build)
3701 and Makefile_win32_debug.txt (debug build) that work on Win95.
3702 Run each of the following from the src directory:
3703 nmake /f Makefile_win32.txt # compiles normal build
3704 nmake /f Makefile_win32.txt install # compiles and installs
3705 nmake /f Makefile_win32.txt clean # removes compiled junk

3707 nmake /f Makefile_win32_debug.txt install
3708 nmake /f Makefile_win32_debug.txt clean
3711 *) Added binbuild.sh and findprg.sh helpers to make it easier for us
3712 to build binary distributions. [Lars Eilebrecht]
3714 *) IndexOptions SuppressColumnSorting only turned off making
3715 the column headers anchors; you could still change the display
3716 order by manually adding a '?N=A' or similar query string to the
3717 URL. Now SuppressColumnSorting locks in the sort order so
3718 it can't be overridden this way. [Ken Coar]
3720 *) Added IndexOrderDefault directive to supply a default sort order
3721 for FancyIndexed directory listings. [Ken Coar] PR#1699
3723 *) Change the ap_assert macro to a variant that works on all platforms.
3724 [Richard Prinz <richard.prinz@cso.net>] PR#2575
3726 *) Make sure under ELF-based NetBSD (now) and OpenBSD (future) we don't
3727 search for an underscore on dlsym() (as it's already the case
3728 for FreeBSD 3.0). [Todd Vierling <tv@pobox.com>] PR#2462
3730 *) Small fix for mod_env.html: The module was documented as to be _not_
3731 compiled into Apache per default, although it _IS_ compiled into
3732 Apache per default. [Sim Harbert <sim@mindspring.com>] PR#3572
3734 *) Instead of fixing a bug in the generation procedure for config.status (a
3735 backslash was missing) we remove the bug together with it's complete
3736 context because the special cases of the past can now no longer occur
3737 because of the recent magic for the --with-layout default.
3738 [Ralf S. Engelschall] PR#3590
3740 *) Make top-level Makefile aware of a parallel build procedures (make -j) by
3741 making sure the src/support/ tools are _forced_ to be build last (they
3742 depend on other libraries).
3743 [Markus Theissinger <markus.theissinger@gmx.de>]
3745 *) Fix installation procedure: Now that os-inline.c is actually used (a
3746 recently fixed bug prevented this) we need to also install os-include.c
3747 in addition to os.h into the PREFIX/include/ location or building of
3748 module DSOs with APXS fails. [Ralf S. Engelschall] PR#3527
3750 *) Added MODULE_MAGIC_COOKIE as the first field in a module structure to
3751 allow us to distinguish between a garbled DSO (or even a file which isn't
3752 an Apache module DSO at all) and a DSO which doesn't match the current
3753 Apache API. [Ralf S. Engelschall] PR#3152
3755 *) Two minor enhancements to mod_rewrite: First RewriteRule now also
3756 supports the ``nocase|NC'' flag (as RewriteCond already does for ages) to
3757 match case insensitive (this especially avoids nasty patterns like
3758 `[tT][eE][sS][tT]'). Second two additional internal map functions
3759 `escape' and `unescape' were added which can be used to escape/unescape
3760 to/from hex-encodings in URLs parts (this is especially useful in
3761 combination with map lookups).
3762 [Magnus Bodin, Ian Kallen, Ralf S. Engelschall]
3764 *) Renamed the macro escape_uri() to ap_escape_uri() which was
3765 forgotten (because it was a macro) in the symbol renaming process.
3766 [Ralf S. Engelschall]
3768 *) Fix some inconsistencies related to the scopes of directives. The only
3769 user visible change is that the directives `UseCanonicalName' and
3770 `ContentDigest' now use the (more correct) `Options' scope instead of
3771 (less correct) `AuthConfig' scope. [Ralf S. Engelschall]
3773 *) Using DSO, the Server token was being mangled. Specifically, the
3774 module's token was being added first before the Apache token. This
3775 has been fixed. [Jim Jagielski]
3777 *) Major overhaul of mod_negotiation.c, part 2.
3778 - properly handle "identity" within Accept-Encoding.
3779 - allow encoded variants in RVSA negotiation and let them appear in
3780 the Alternates field using the non-standard "encoding" tag-list.
3781 - fixed both negotiation algorithms so that an explicitly accepted
3782 encoding is preferred over no encoding if "identity" is not
3783 included within Accept-Encoding.
3784 - added ap_array_pstrcat() to alloc.c for efficient concatenation
3785 of large substring sequences.
3786 - replaced O(n^2) memory hogs in mod_negotiation with ap_array_pstrcat.
3789 *) Major overhaul of mod_negotiation.c, part 1.
3790 - cleanups to mod_negotiation comments and code structure
3791 - made compliant with HTTP/1.1 proposed standard (rfc2068) and added
3792 support for everything in the upcoming HTTP/1.1
3793 revision (draft-ietf-http-v11-spec-rev-06.txt).
3794 - language tag matching also handles tags with more than 2
3796 - empty Accept, Accept-Language, Accept-Charset headers are
3797 processed correctly; previously an empty header would make all
3798 values acceptable instead of unacceptable.
3799 - allowed for q values in Accept-Encoding
3800 - added support for transparent content negotiation (rfc2295 and
3801 rfc2296) (though we do not implement all features in these drafts,
3802 e.g. no feature negotiation). Removed old experimental version.
3803 - implemented 'structured entity tags' for better cache correctness
3804 (structured entity tags ensure that caches which can deal with Vary
3805 will (eventually) be updated if the set of variants on the server
3807 - this involved adding a vlist_validator element to request_rec
3808 - this involved adding the ap_make_etag() function to the global API
3809 - modified guessing of charsets used by Apache negotiation algorithm
3810 to guess 'no charset' if the variant is not a text/* type
3811 - added code to sort multiviews variants into a canonical order so that
3812 negotiation results are consistent across backup/restores and mirrors
3813 - removed possibility of a type map file resolving to another type map
3814 file as its best variant

3844 *) Update APXS manual page: some -q option arguments were missing
3845 and another was incorrect. [Mark Anderson <mda@discerning.com>] PR#3553
3847 *) Cleanup the command line options: `-?' was documented to show
3848 the usage list but does it with an error because `?' is not a valid
3849 command. OTOH a lot of users expect `-h' to print such a usage list and
3850 instead are annoyed for ages by our huge unreadable list of directives.
3851 So we now changed the command line options this way:
3853 Intent: we need `-L' to be free, and `-R' for the DSO run-time path is
3854 very similar to the popular linker option.
3856 Intent: while -l gives the small list of modules, -L now gives the
3857 large list of directives implemented by these modules. This is also
3858 consistent with -v (short version info) and -V (large version info).
3860 Intent: it's now the expected option ;-)
3861 The manual page was adjusted accordingly.

3864 *) Fixed problem of fclose() on an unopened file in suexec if LOG_EXEC
3865 wasn't defined. [Rick Franchuk <rickf@transpect.net>]
3867 *) Removed recently introduced bugs and disfigurements in APACI:
3868 o fixed argument line processing: using $args was broken: It was not
3869 initialized and using args="$args $apc_option" and even args="$args
3870 \"$apc_option\"" fails in the second processing round for any arguments
3871 containing whitespaces. The only correct way is to use the construct
3872 "$@" (but not possible here) or iterate _both_ times over the implicit
3873 argument line (no argument to for-loop) which is what we now use.
3874 o make --with-layout=Apache the default without creating
3875 redundancy (copying the --with-layout block in the argument parsing
3876 loop). We achieve this by using the "$@" construct together with the
3877 `set' command to prepend --with-layout=Apache to the command line in
3878 case --with-layout is not used.
3879 o fixed auto-suffix handling now that config.layout exists.
3880 Paths which are auto-suffixed are marked with a trailing plus sign in
3881 config.layout and every path now can be marked this way (not only the
3882 four paths for which we do it currently). Additionally the suffix is
3883 no longer a static one. Instead it's now `/<target>' where <target> is
3884 the argument of the --target option or per default `httpd'.
3885 o allow also tabs (and only spaces) where we match whitespaces
3886 o various fixes and cleanups related to used shell coding style
3887 o made Jim happy by replacing `Written by' with `Initially written by' ;-)
3888 o trimmed output of --help to fit into 80 columns

3920 since 1.3b7) and make whitespace handling more robust (it failed horrible
3921 when whitespaces were present in the arguments of -D options).
3922 [Ralf S. Engelschall] PR#3240
3924 *) Add APACI --shadow=DIR variant (in addition to --shadow). This now first
3925 creates an external package shadow tree in DIR before the local build
3926 shadow tree is generated under DIR. This way one can have the extracted
3927 Apache distribution tree read-only on NFS or CDROM and still build Apache
3928 from these sources. An automatically triggered VPATH-like mechanism is
3929 provided through the TOP variable, too.

3932 *) Fix negotiation so that a Vary response header is correctly
3933 generated when, for a particular dimension, variants only vary
3934 in having or not having a value for that dimension. [Paul Sutton]
3936 *) Fix negotiation so that we prefer an encoded variant over an
3937 unencoded variant if the user-agent explicitly says it can
3938 accept that encoding. Previously we always preferred the unencoded
3940 [Paul Ausbeck <paula@alumni.cse.ucsc.edu>, Paul Sutton] PR#3447
3942 *) Fix APXS tool: query variables LIBS_SHLIB and TARGET were not recognized
3943 and the usage page was inconsistent with the functionality and manpage.
3944 [Ralf S. Engelschall]
3946 *) Allow special options -Wc,xxx and -Wl,xxx on APXS compile/link command.
3947 They can occur multiple times and their arguments (`xxx') are passed AS
3948 IS to the compiler/linker command. [Ralf S. Engelschall]
3950 *) Fixed possible (but harmless in practice) bug in the DBM lookup
3951 procedure of mod_rewrite: very long keys were truncated.
3952 [Ralf S. Engelschall]
3954 *) Added a generic --with-layout=[FILE:]ID option. ID here is a layout
3955 identifier, currently "Apache" and "GNU" are pre-defined in the file
3956 config.layout. Custom layouts are possible by using FILE:ID as the
3957 argument where the layout ID is taken from FILE.
3959 The config.layout file consists of <Layout ID>..</Layout> sections
3960 where inside those sections "path_variable: path_value" pairs can be
3961 specified. These lines are converted to path_variable='path_value'.
3963 *) Add a DefaultLanguage directive so that files missing a language
3964 extension (e.g., .fr, .de) can be labelled as being some other
3965 default language. DefaultLanguage can appear in <Directory> and
3966 <Files> containers as well as .htaccess files. [Paul Sutton]
3969 *) Fix TARGET configuration when configuring and installing using
3970 APACI configure. TARGET now defines the basename of the configuration
3971 file, startup script, manual page, etc. log_error_core() now reports
3972 the server binary name given by argv[0]. TARGET can now also be defined
3973 with --target=TARGET parameter passed to APACI configure.

3976 *) mod_include.c:handle_perl() now properly tests for OPT_INCNOEXEC
3977 rather than OPT_INCLUDES [Rainer Schoepf <schoepf@uni-mainz.de>]

3996 notice to the error log. It is not possible to send a 401 response
3997 and a redirect at the same time. [Lars Eilebrecht]
3999 *) Fallback to native compilers for IRIX-32 platform. It seems that
4000 a gcc 2.8.1 compiled apache is logging client addresses with all
4001 bits set (255.255.255.255). This is the second such problem caused
4002 by gcc 2.8.1 compiler. The first being broken semaphore locking.
4005 *) Updated mime.types to reflect current Internet media types
4006 and include a URL to the registry.

4009 *) SECURITY: Do a more complete check in mod_include to avoid
4010 an infinite loop of recursive SSI includes. [Marc Slemko] PR#3323

4013 used to set the document root directory (DOC_ROOT) and the suexec
4014 logfile (LOG_EXEC), respectively. Additionally the --layout option
4015 was changed to show more information about the suEXEC setup.

4018 *) Added the last two WebDAV status codes of 424 (Failed Dependency)
4019 and 507 (Insufficient Storage) for use by third-party modules.
4022 *) Enabled all of the WebDAV method names for use by third-party
4023 modules, Limit, and Script directives. That includes PATCH,
4024 PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
4025 Improved mod_actions.c so that it can use any of the methods
4026 defined in httpd.h. Added ap_method_number_of(method) for

4050 the interpreter and the Win32 error code returned. [Marc Slemko]
4052 *) Disable sending of error-notes on a 500 (Internal Server Error) response
4053 since it often includes file path info. Enable sending of error-notes
4054 on a 501 (Method Not Implemented). [Roy Fielding] PR#3173
4056 *) http_config.c would respond with 501 (Method Not Implemented) if a
4057 content type handler was specified but could not be found, which
4058 should have been a 500 response. Likewise, mod_proxy.c would responsd
4059 with a 501 if the URI scheme is unrecognized instead of the correct
4060 response of 403 (Forbidden). [Roy Fielding]
4062 *) SECURITY: Eliminate DoS attack when a bad URI path contains what
4063 looks like a printf format escape. [Marc Slemko, Studenten Net Twente]

4066 unavailable, an empty string was printed which was 2 bytes short.
4067 The size and description columns were therefore not aligned correctly.

4079 *) Add APACI --permute-module=foo:bar option which can be used to
4080 on-the-fly/batch permute the order of two modules (mod_foo and mod_bar)
4081 in the Configuration[.apaci] file. Two special and important variants are
4082 supported for the option argument: first BEGIN:foo which permutes module
4083 mod_foo with the begin of the module list, i.e. it `moves' the module to
4084 the begin of the list (gives it lowest priority). And second foo:END
4085 which permutes mod_foo with the end of the module list, i.e. it `moves'
4086 the module to the end of the list (gives it highest priority).

4157 Changes with Apache 1.3.3
4159 *) Added a complete implementation of the Expect header field as
4160 specified in rev-05 of HTTP/1.1. Disabled the 100 Continue
4161 response when we already know the final status, which is mighty
4162 useful for PUT responses that result in 302 or 401. [Roy Fielding]
4164 *) Remove extra trailing whitespace from the getline results as part
4165 of the protocol processing, which is extra nice because it works
4166 between continuation lines, is almost no cost in the normal case
4167 of no extra whitespace, and saves memory. [Roy Fielding]
4169 *) Added new HTTP status codes and default response bodies from the
4170 revised HTTP/1.1 (307, 416, 417), WebDAV (102, 207, 422, 423), and
4171 HTTP Extension Framework (510) specifications. Did not add the
4172 WebDAV 424 and 425 codes because they are bogus. We don't use any
4173 of these codes yet, but they are now available to 3rd-party modules.

4289 You now must define a BS2000Account name for the server User.
4290 This has fewer security implications than the old approach.
4293 *) Fix SHARED_CORE feature for HPUX platform: We now use extension `.sl'
4294 instead of `.so' and `SHLIB_PATH' instead of `LD_LIBRARY_PATH' on this
4295 platform to make the braindead HPUX linker happy. Notice, for the module
4296 DSOs we don't have to use this, because these are loaded manually (and

4308 *) Make PrintPath work generically instead of having one version
4309 strictly for OS/2. [Jim Jagielski, Brian Havard]
4311 *) Fix the recently introduced C header file checking: We now use the C
4312 pre-processor pass only (and no longer the complete compiler pass) to
4313 determine whether a C header file exists or not. Because only this way
4314 we're safe against inter-header dependencies (which caused horrible
4315 portability problems). The only drawback is that we now have a CPP
4316 configuration variable which has to be determined first (we do a similar
4317 approach as GNU Autoconf does here). When all fails the user still has
4318 the possibility to override it manually via APACI or src/Configuration.
4319 As a fallback for the header check itself we can directly check the
4320 existance of the file under /usr/include, too.

4351 *) Remove `-msym' option from LDFLAGS_SHLIB for the Digital UNIX (OSF/1)
4352 platform, because it's only supported under version 4.0 and higher. But
4353 because our GuessOS is still unaware of Digital UNIX versions and the
4354 -msym is just to optimize the DSO statup time a little bit it's safe and
4355 best when we leave it out now. [Ralf S. Engelschall] PR#2969

4360 (instead it directly passes through the message to be formatted to the
4361 real internal formatting function). [Ralf S. Engelschall] PR#2941
4363 *) Allow "Include" directives anywhere in the server config
4364 files (but not .htaccess files). [Ken Coar] PR#2727
4366 *) The proxy was refusing to serve CONNECT requests except to
4367 port 443 (https://) and 563 (snews://). The new AllowCONNECT
4368 directive allows the configuration of the ports to which a
4369 CONNECT is allowed. [Sameer Parekh, Martin Kraemer]
4371 *) mod_expires will now act on content that is not sent from a file
4372 on disk. Previously it would never add an Expires: header to
4373 any response that did not come from a file on disk; the only
4374 case where it still doesn't (and can't) add one for that type of
4375 content is if you are using a modification date based setting.

4390 *) As duplicate "HTTP/1.0 200 OK" lines within the header seem to be
4391 a common problem of (mis-administrated?) IIS servers, make the apache
4392 proxy immune to these errors (and ignore the duplicates, but log
4393 the fact to error_log). [Martin Kraemer], after the proposal in PR#2914
4395 *) The <IfModule and <IfDefine block starting directives now only
4396 allow exactly one argument. Previously, the optional negation
4397 character '!' could be separated by whitespace without a syntax
4398 error being reported, albeit defeating the IfModule functionality
4399 (enclosed directives would ALWAYS be executed). By using the
4400 stricter syntax, these hard-to-track errors can be avoided.
4403 *) Simplify handling of IndexOptions in mod_autoindex -- and BTW
4404 cause the standalone FancyIndexing directive to logically OR

4406 them out. [Ken Coar]
4408 *) Changes in ftp proxy: make URL parsing simpler by using the
4410 + Add display of the "current directory" in cases where it's
4411 different from the supplied path (e.g., ftp://user@host/ lives
4412 in /home/user, not in /, therefore clicking on "../" in the
4413 starting directory might send us to /home/).
4414 + When ftp login fails, (esp. when a user name was part of the
4415 URL already), we now return [401 Unauthorized ] to allow the
4416 browser to pop up an authorization dialog. This makes passwords
4417 slightly less visible (they don't appear in the regular log files)
4418 and implements a functionality that other www proxy servers
4422 *) Triggered by the recent "Via:" header changes, the proxy module would
4423 dump core for replies with invalid headers (e.g., duplicate
4424 "HTTP/1.0 200 OK" lines). These errors are now logged and the
4425 core dump is avoided. Also, broken replies are not cached.

4436 adjustment feature (no --without-confadjust) with calls to a new helper

4460 *) Bump up MAX_ENV_FLAGS in mod_rewrite.h from the too conservatice limit of
4461 5 to 10 because there are some users out there who always have 5 to 8
4462 variables in one RewriteRule and had to patch mod_rewrite.h for every

4464 needed more than 4 in my RewriteRules ;-)

4490 vhost, request and client information is not displayed.
4493 *) STATUS is no longer available. Full status information now
4494 run-time configurable using the ExtendedStatus directive.
4497 *) SECURITY: Eliminate O(n^2) space DoS attacks (and other O(n^2)
4498 cpu time attacks) in header parsing. Add ap_overlap_tables(),
4499 a function which can be used to perform bulk update operations
4500 on tables in a more efficient manner. [Dean Gaudet]
4502 *) SECURITY: Added compile-time and configurable limits for
4503 various aspects of reading a client request to avoid some simple
4504 denial of service attacks, including limits on maximum request-line
4505 size (LimitRequestLine), number of header fields (LimitRequestFields),
4506 and size of any one header field (LimitRequestFieldsize). Also added
4507 a configurable directive LimitRequestBody for limiting the size of the

4527 state even without full STATUS accounting. [Jim Jagielski]

4541 the ugly use of an env. variable and use command-line args for
4542 alternate $PATH. Make more like advanced 'type's as well.

4553 directory was renamed to src/os/os2/ for consistency.
4554 [Brian Havard, Ralf S. Engelschall]
4556 *) Add new Rule SHARED_CHAIN which can be used to enable linking of DSO
4557 files (here modules) against other DSO files (here shared libraries).
4558 This is done by determining a subset of LIBS which can be safely used for
4559 linking the DSOs, i.e. PIC libs and shared libs. Currently the rule is
4560 disabled for all platforms to avoid problems with this (experimental)
4561 rule. But we provide it now for those people how ran into problems and
4562 want to came out by forcing linking against DSOs.

4874 than strcmp() to check for parent directory-ness of an entry. Oh, and
4875 make sure the parent directory (if displayed) is *always* listed first
4876 regardless of the sort key. Overall performance winnage should be good
4877 in CPU time, instruction cache, and memory usage, particularly for large

4887 *) Add httpd -t (test) option for running configuration syntax tests only.
4888 If something is broken it complains and exits with a return code
4889 non-equal to 0. This can be used manually by the user to check the Apache
4890 configuration after editing and is also automatically used by apachectl
4891 on (graceful) restart command to make sure Apache doesn't die on restarts
4892 because of a configuration which is now broken since the last (re)start.

4916 [Ralf S. Engelschall] PR#2378
4918 *) Make sure the "install" target of the top-level Makefile doesn't break
4919 because of a return code of 1 from an "if" (for instance under braindead
4920 Ultrix the result code of an "if" construct is 1 if the "then" clause
4921 didn't match). [Ralf S. Engelschall]
4923 *) Add an additional "dummy" target to the "$(LIB)" target in generated
4924 modules/xxx/Makefile's to avoid problems with SVR4 Make under "full-DSO"

5033 ap_spawn_child_err became ap_spawn_child
5034 ap_spawn_child_err_buff became ap_bspawn_child
5035 spawn_child was obsoleted and moved to compat.h
5038 *) Upgrade the child spawning code in mod_rewrite for the RewriteMap
5039 programs: ap_spawn_child_err() is used and the Win32 case now uses
5040 CreateProcess() instead of a low-level execl() (which caused problems in
5041 the past under Win32).
5042 [Ralf S. Engelschall]
5044 *) A few cosmetics and trivial enhancements to APXS to make the
5045 generated Makefile more user friendly. [Ralf S. Engelschall]
5047 *) Proxy Fix: The proxy special failure routine ap_proxyerror()
5048 was updated to use the normal apache error processing, thereby allowing
5049 proxy errors to be treated by ErrorDocument's as well. For this
5050 purpose, a new module-to-core communication variable "error-notes"
5051 was introduced; the proxy (and possibly other modules) communicates
5052 its error text using this variable. Its content is copied to a new
5053 cgi-env-var REDIRECT_ERROR_NOTES for use by ErrorDocuments.
5054 The old proxy special error routine ap_proxy_log_uerror()
5055 was replaced by regular ap_log_error() calls, many messages were made
5057 [Martin Kraemer] PR#494, 1259
5059 *) SECURITY: A possible buffer overflow in the ftp proxy was fixed.
5062 *) Transform the configure message "You need root privileges for suEXEC"
5063 from a fatal error into a (more friendly) warning because the building
5064 ("make") of Apache we can allow, of course. Root privileges are needed
5065 only for the installation step ("make install"). So make sure the
5066 user is aware of this fact but let him proceed as long as he can.

5085 Changes with Apache 1.3b7
5087 *) Make sure a MIME-type can be forced via a RewriteRule even when no
5088 substitution takes place, for instance via the following rule:
5089 ``RewriteRule ^myscript$ - [T=application/x-httpd-cgi]'' This was often
5090 requested by users in the past to force a single script without a .cgi
5091 extension and outside any cgi-bin dirs to be executed as a CGI program.

5094 *) A fix for protocol issues surrounding 400, 408, and

5099 *) Fix discrepancy in proxy_ftp.c which was causing failures when
5100 trying to connect to certain ftpd's, such as anonftpd.
5101 [Rick Ohnemus <rick@ecompcon.com>]
5103 *) Make mod_rewrite use ap_open_piped_log() for RewriteLog directive's
5104 logfile instead of fiddling around itself with child spawning stuff.
5105 [Ralf S. Engelschall]
5107 *) Made RefererIgnore case-insensitive.
5109 *) Mod_log_agent, mod_log_referer now use ap_open_piped_log for piped logs.
5112 *) Replace use of spawn_child with ap_spawn_child_err_buff, to make everything
5113 "safe" under Win32. In: mod_include.c, mod_mime_magic.c
5116 *) Improve RFC1413 support. [Bob Beck <beck@bofh.ucs.ualberta.ca>]
5118 *) Fix support script `dbmmanage': It was unable to handle some sort
5119 of passwords, especially passwords with "0" chars.
5120 [Ralf S. Engelschall] PR#2242
5122 *) WIN32: Clicking on "Last Modified" in a fancy index caused a crash. Fixed.
5123 [Ben Laurie] PR#2238
5125 *) WIN32: CGIs could cause a hang (because of a deadlock in the standard C
5126 library), so CGI handling has been changed to use Win32 native handles
5127 instead of C file descriptors.
5128 [Ben Laurie and Bill Stoddard <wgstodda@us.ibm.com>] PR#1129, 1607
5130 *) The proxy cache would store an incorrect content-length in the cached
5131 file copy after a cache update. That resulted in repeated fetching
5132 of the original copy instead of using the cached copy.
5133 [Ernst Kloppenburg <kloppen@isr.uni-stuttgart.de>] PR#2094
5135 *) The Makefiles assumed that DSO files are build via $(LD). This
5136 is broken for two reasons: First we never defined at least LD=ld
5137 somewhere to make sure this works (it was silently assumed that most Make
5138 provide a built-in LD definition - ARGL!) and second using the generic LD
5139 variable is not the truth. Instead a special variable named LD_SHLIB is
5140 reasonable because although "ld" is usually the default, the command for
5141 building DSO files can be "libtool" or even "cc" on some systems.
5142 [Ralf S. Engelschall]
5144 *) Replace the AddVersionPlatform directive with ServerTokens which
5145 provides for more control over the format of the Server:
5146 header line. SERVER_SUBVERSION is no longer supported;
5147 all module should use the ap_add_version_component()
5148 API function instead. [Jim Jagielski]
5150 *) Support for the NCR MP/RAS 3.0
5151 [John Withers <withers@semi.kcsc.mwr.irs.gov>]
5153 *) The LDFLAGS_SHLIB_EXPORT variable of src/Configuration[.tmpl] was
5154 not retrieved in src/Configure and thus was not useable.
5155 [Ralf S. Engelschall]
5157 *) Various Makefile consistency cleanups:
5158 - make OSDIR also automatically be relative to src/ like INCDIR
5159 - SUBDIRS is now generated in src/Makefile only and not in
5160 Makefile.config because it is a local define for this location.
5161 - remove BROKEN_BPRINTF_FLAGS because is it no longer used inside
5162 any Makefile but make sure that at least the "-K inline" is kept in
5164 - update the "depend" targets in Makefile.tmpl files to use $(OSDIR), too.
5165 - updated the dependencies theirself
5166 - removed not existing SHLIB variable from "clean" targets
5167 - replaced SHLIB_OBJS/SHLIBS_OBJ consistently with OBJS_PIC because OBJS
5168 already exists and OBJS_PIC are also just plain objects and have not
5169 directly to do with "shared" things. The only difference is that they
5170 contain PIC. So OBJS_PIC is the more canonical name.
5171 - Updated the Makefile-dependency lines for OBJS_PIC
5172 - Removed the Makefile-dependency line in Configure to avoid double
5174 - replaced ugly xx-so.o/xx.so-o hack with a clean and consistent usage
5175 of xxx.lo as GNU libtool does with its PIC objects
5176 - reduce local complexity in modules Makefile.tmpl by moving the last
5177 existing target "depend" to the generation section in Configure, too.
5178 - removed the historical $(SPACER) which was used in the past together
5179 with BROKEN_BPRINTF_FLAGS to avoid zig-zags in the build process. This
5180 is no longer needed.
5181 - force the build and run of the gen_xxx programs under main/ as the
5182 first step before building the objects because it looks cleaner
5183 [Ralf S. Engelschall]
5185 *) WIN32: Make Win32 work again after the /dev/null DoS fix.
5188 *) WIN32: Check for buffer overflows in ap_os_canonical_filename.
5191 *) WIN32: Don't force ISAPI headers to finish with \n.
5192 [Jim Patterson <Jim.Patterson@Cognos.COM>, Ben Laurie] PR#2060
5194 *) When opening "configuration" files (like httpd.conf, htaccess
5195 and htpasswd), Apache will not allow them to be non-/dev/null
5196 device files. This closes a DoS hole. At the same time,
5197 we use ap_pfopen to open these files to handle timeouts.
5198 [Jim Jagielski, Martin Kraemer]
5200 *) Apache will now log the reason its httpd children exit if they exit
5201 due to an unexpected signal. (It requires a new porting define,
5202 SYS_SIGLIST, which if defined should point to a list of text
5203 descriptions of the signals available. See PORTING.) [Dean Gaudet]
5205 *) WIN32: chdir() doesn't make sense in a multithreaded environment
5206 like WIN32. Before, Win32 CGI's could have had sporadic failures
5207 if a chdir call from one thread was made between another chdir call
5208 and a spawn in another thread. So, for now don't chdir for CGI scripts
5209 in WIN32. The current CGI "spec" is unclear as to whether it's
5210 necessary. Long-term fix is to either serialize the chdir/spawn combo
5211 or use WIN32 native calls to spawn a process. This temp fix was
5212 necessary to remove this as a showstopper for 1.3's release.
5215 *) Cleanup the suEXEC support in APACI and make it more safe:
5216 1. Add big fat hint in INSTALL about risks and to read the
5217 htdocs/manual/suexec.html document before using the suexec-related
5219 2. Make sure the user has at least provided one --suexec-xxxx option
5220 (specifies suEXEC parameters) in addition to --enable-suexec option.
5221 If only --enable-suexec is given APACI stops with a hint to INSTALL
5222 and htdocs/manual/suexec.html documents.
5223 3. Provide two additional --suexec-xxxx options to make the suEXEC
5224 configuration complete (especially for package maintainers who else
5225 had to patch the source tree) by providing ways to configure minimal
5226 UID/GID and safe PATH, too.
5227 [Ralf S. Engelschall]
5229 *) Cleanup of the `configure --shadow' process:
5230 - make sure the configure script creates its temporary files in the
5231 shadow tree to avoid conflicts with parallel configure runs
5232 - removed unnecessary option "-r" from "rm" call for Makefiles
5233 - make sure the configure scripts creates the shadow-wrapper Makefile
5234 only when no shadow trees already exists
5235 - make sure "make distclean" removes the shadow-wrapper Makefile but only
5236 when no more shadow trees exists
5237 - overhauled mkshadow.sh script: now its more IFS-safe and approx. twice
5238 as fast (in the past it needed 70sec, now it runs just 38sec)
5239 - make sure CVS does not complain about the created files
5240 Makefille.<gnutriple> and directories src.<gnutriple>
5241 [Ralf S. Engelschall]
5243 *) Added the ap_add_version_component() API routine and the
5244 AddVersionPlatform core directive. The first allows modules to
5245 declare themselves in the Server response header field value,
5246 augmenting the SERVER_SUBVERSION define in the Configuration file
5247 with run-time settings (more useful in a loadable-module environment).
5248 AddVersionPlatform inserts a comment such as "(UNIX)" or "(Win32)"
5249 into the server version string. [Ken Coar] PR#2056
5251 *) Minor stability tweaks to avoid core dumps in ap_snprintf.
5254 *) Emit the "Accept-Range" header for the default handler.
5255 [Brian Behlendorf] PR#1464
5257 *) Add a note to httpd.conf-dist that apache will on some systems fail
5258 to start when the Group # is set to a negative or large positive value.
5261 *) Make sure the module execution order is correct even when some modules
5262 are loaded under runtime (`LoadModule') via the DSO mechanism:
5263 1. The list of loaded modules is now a dynamically allocated one
5264 and not the original statically list from modules.c
5265 2. The loaded modules are now correctly setup by LoadModule for
5266 later use by the AddModule command.
5267 3. When the DSO mechanism for modules is used APACI's `install'
5268 target now enables all created `LoadModule' lines per default because
5269 this is both already expected by the user _and_ needed to avoid
5270 confusion with the next point and reduces the Makefile.tmpl complexity
5271 4. When the DSO mechanism for modules is used, APACI's `install'
5272 target now additionally makes sure the module list is reconstructed
5273 via a complete `ClearModuleList+AddModule...' entry.
5274 5. The support tool `apxs' now also makes sure an AddModule command
5275 is added in addition to the LoadModule command.
5276 6. The modules.c generation was extended to now contain two
5277 comments to make sure no one is confused by the confusing terminology
5278 of loading/linking (we use load=link+load & link=activate instead of
5279 the obvious load=activate & link=link :-( )
5280 This way now there is no longer a difference under execution time between
5281 statically and dynamically linked modules.
5282 [Ralf S. Engelschall]
5284 *) Fix the generated mod_xxx.c from "apxs -g -f xxx" after the
5285 Big Symbol Renaming. [Ralf S. Engelschall]
5287 *) Add a comment to mod_example.c showing the format of a FLAG command
5290 *) Standardized the time format in mod_status to match that of other
5291 places in the code (e.g. DATE_GMT). PR#1551
5293 *) Fix handling of %Z in timefmt strings for those platforms with no time
5294 zone information in their tm struct. [Paul Eggert <eggert@twinsun.com>]
5297 *) Makes mod_rewrite, mod_log_config, mod_status and the ServerSignature
5298 feature compatible with 'UseCanonicalName off' by changing
5299 r->server->server_hostname to ap_get_server_name(). And I changed some
5300 functions which use r->server->port to use ap_get_server_port() instead,
5301 because if there's no Port directive in the config r->server->port is 0.
5304 *) get/set_module_config are trivial enough to be better off inline. Worth
5305 1.5% performance boost. [Dean Gaudet]
5307 *) Fix off-by-one error in ap_proxy_date_canon() in proxy_util.c
5308 when ensuring 'x' is at least 30-chars big. [Jim Jagielski,
5311 *) [BS2000 security] BS2000 needs an extra authentication to initialize
5312 the task environment to the unprivileged User id. Otherwise CGI scripts
5313 would have a way to gain super user access. [Martin Kraemer]
5315 *) Fix debug log messages for BS2000/OSD: instead of logging the whole
5316 absolute path, only log base name of logging source as is done
5317 in unix. [Martin Kraemer]
5319 *) Ronald Tschalaer's Accept-Encoding patch - preserve the "x-" in
5320 the encoding type from the Accept-Encoding header (if it's there)
5321 and use it in the response, as that's probably what it'll be expecting.
5322 [Ronald.Tschalaer@psi.ch]
5324 *) Fix to mod_alias: translate_alias_redir is dealing with
5325 a URI, not a filename, so the check for drive letters for win32
5326 and emx is not necessary. [Dean Gaudet]
5328 *) WIN32: Allow .cmd as an executable extension.
5329 [Kari Likovuori <Kari.Likovuori@mol.fi>] PR#2146
5331 *) Make Apache header files, and some variables, C++ friendly.
5332 [Michael Anderson's <mka@redes.int.com.mx>]
5334 *) Child processes can now "signal" (by exiting with a status
5335 of APEXIT_CHILDFATAL) the parent process to abort and
5336 shutdown the server if the error in the child process was
5337 fatal enough. [Jim Jagielski]
5339 *) mod_autoindex's find_itme() was sensitive to MIME type case.
5340 [Jim Jagielski] PR#2112
5342 *) Make sure the referer_log and agent_log entries in the default httpd.conf
5343 file are also adjusted for the actual relative installation paths.
5344 [Ralf S. Engelschall] PR#2175
5346 *) WIN32: Extensive overhaul of the way UNCs are handled. [Ben Laurie]
5348 *) WIN32: Make roots of filesystems (e.g. c:/) work. [Ben Laurie]
5351 *) PORT: Various porting changes to support AIX 3.2, 4.1.5, 4.2 and 4.3.
5352 Additionally the checks for finding the vendor DSO library were moved
5353 from mod_so.c to Configure because first it needs $PLAT etc. and second
5354 mod_so already uses an abstraction layer and does not fiddle with the
5355 vendor functions itself.
5356 [Jens-Uwe Mager, Ralf S. Engelschall]
5358 *) PORT: Some optimization defines for NetBSD
5359 [Jaromir Dolecek <dolecek@ics.muni.cz>] PR#2165
5361 *) PORT: Dynamic Shared Object (DSO) support for NetBSD.
5362 [Jaromir Dolecek <dolecek@ics.muni.cz>, Ralf S. Engelschall] PR#2158
5364 *) Add Dynamic Shared Object (DSO) support for AIX (at least 4.2 but older
5365 AIX variants should work fine, too. Even AIX 3.x should work). This is
5366 accomplished by using the free DSO emulation code from Jens-Uwe Mager
5367 which we put into a os/unix/os-dso-aix.c file.
5368 [Ralf S. Engelschall]
5370 *) PORT: Fix compiler warnings under AIX >= 4.2 where the manual pages imply
5371 that we should use NET_SIZE_T == int but the include files force size_t.
5372 [Ralf S. Engelschall]
5374 *) Fix two bugs in select() handling in http_main.c.
5377 *) Suppress "error(0)" messages for ap_log_error() when the APLOG_NOERRNO
5378 is unset (as it is in situations like timeouts) where it is unclear
5379 whether errno is set or not. [Martin Kraemer]
5381 *) Just having APACI's localstatedir is too general and not enough for most
5382 of the systems. 1.3b6 again required manual APACI patches by package
5383 maintainers from RedHat and FreeBSD because for their filesystem layout a
5384 little bit more flexibility in configuring the paths is needed. Hence we
5385 provide three additional configure options (--runtimedir, --logfiledir,
5386 --proxycachedir) which now can be used for more granular adjustments if
5387 --localstatedir is not enough to fit the particular needs. As a nice
5388 side-effect this reduces some subdir fiddling in configure+Makefile.tmpl.
5389 [Ralf S. Engelschall]
5391 *) Make the install root for "make install" in APACI's Makefile overrideable
5392 by package authors. This way we are even more friendly to package
5393 maintainers (especially Debian and RedHat) who build for the real prefix
5394 via "configure --prefix=/<real>" but use a different local prefix via
5395 "make root=/tmp/apache install" for rolling the package without bristling
5396 the target location on their system.
5397 [Ralf S. Engelschall]
5399 *) Workaround sed limitations in APACI's configure script by now
5400 substituting in chunks of 50 commands (because for instance HPUX's vendor
5401 sed has a limit of max. 98 commands)
5402 [Ralf S. Engelschall] PR#2136
5404 *) Adding SOCKS5 support and fixing existing SOCKS4 support.
5405 [Ralf S. Engelschall] PR#2140
5407 *) Manually fix some symbols which were not renamed to prefix ap_ in the BIG
5408 RENAMING process because they are defined as pre-processor macros instead
5409 of real functions: bputc, bgetc, piped_log_write_fd, piped_log_read_fd
5410 [Ralf S. Engelschall]
5412 *) Workaround braindead AWK's when generating ap_config.h: The split() and
5413 substr() functions cannot be nested under vendor AWK from Solaris 2.6.
5414 [Ralf S. Engelschall] PR#2139
5416 *) Various bugfixes and cleanups for the APACI configure script:
5417 o fix IFS handling for _nested_ situation
5418 o fix Perl interpreter search: take first one found instead of last one
5419 o fix DSO consistency check
5420 o print error messages to stderr instead of stdout
5421 o add install-quiet for --shadow situation to Makefile stub
5422 o reduce complexity by avoiding sed-hacks for rule and module list loops
5423 [Ralf S. Engelschall]
5425 *) Fix DEBUG_CGI situation in mod_cgi.c [David MacKenzie] PR#2114
5427 *) Make sure the input field separator (IFS) shell variable is explicitly
5428 initialized correctly before _every_ `for' loop and also restored after
5429 the loops. [Ralf S. Engelschall]
5431 *) Make sure that "make install" doesn't overwrite the `mime.types' and
5432 `magic' files from an existing Apache installation. Because people often
5433 customize these for own MIME and content types.
5434 [Ralf S. Engelschall]
5436 *) PORT: Dynamic Shared Object (DSO) support for OpenBSD 2.x
5437 [Peter Galbavy, Ralf S. Engelschall] PR#2109
5439 *) Fix the path to the ScoreBoardFile in the install-config target, too.
5440 [Ralf S. Engelschall] PR#2105
5442 *) Let "configure" clear out the users parameters (provided as shell
5443 variables) to avoid side-effects in "src/Configure" when the user
5444 exported them (which is not needed, but some users do it).
5445 [Ralf S. Engelschall] PR#2101
5447 *) Provide backward compatibility from some old src/Configuration.tmpl
5448 parameter names to the canonical Autoconf-style shell variable names. For
5449 instance CFLAGS vs. EXTRA_CFLAGS. The EXTRA_xxx variants are accepted now
5450 but a hint message is displayed. [Ralf S. Engelschall]
5452 *) Make sure that "make install" doesn't overwrite the DocumentRoot and
5453 CGI scripts from an existing Apache installation.
5454 [Ralf S. Engelschall, Jim Jagielski] PR#2084
5456 *) Make `configure --compat' more "compatible" by first
5457 let the libexecdir default to EPREFIX/libexec instead of EPREFIX/bin and
5458 second by making sure the "avoid-bristling-suffix" /apache is not
5459 appended to sysconfdir, datadir, localstatedir and includedir when
5460 --compat is used. [Ralf S. Engelschall, Lars Eilebrecht]
5462 *) NeXT required strdup() in support/logresolve.c
5463 [Francisco Tomei <fatomei@sandburg.unm.edu>] PR#2082
5465 *) AIX required sys/select.h in support/ab.c

5468 *) Fix the path to the MimeMagicFile in the install-config target, too.
5469 [Ralf S. Engelschall] PR#2089
5471 *) PORT: Added HP-UX 11 patches [Jeff Earickson <jaearick@colby.edu>]
5473 *) If you start apache with the -S command line option it will dump
5474 out the parsed vhost settings. This is useful for folks trying
5475 to figure out what is wrong with their vhost configuration.
5476 (Other dumps may be added in the future.) [Dean Gaudet]
5478 *) Add %pA, %pI, and %pp codes to ap_vformatter (and hence ap_bprintf,
5479 ap_snprintf, and ap_psprintf). See include/ap.h for docs.
5482 *) Because /usr/local/apache is the default prefix the ``configure
5483 --compat'' option no longer has to set prefix, again. This way the
5484 --compat option honors a leading --prefix option. [Lars Eilebrecht]
5486 *) PORT: Cast the first argument of dlopen() in ap_os_dso_load()
5487 to `char *' under OSF1 and FreeBSD 2.x where it is defined this way
5488 to avoid "discard const" warnings. [Ralf S. Engelschall]
5490 *) If a specific handler is set for a file yet the request still
5491 ends up being handled by the default handler, log an error
5492 message before handling it. This catches things such as trying
5493 to use SSIs without mod_include enabled. [Marc Slemko]
5495 *) Fix error logging for the startup case where ap_log_error() still uses
5496 stderr as the target. Now the default log level is honored here, too.
5497 [Ralf S. Engelschall]
5499 *) PORT: Make sure some AWK's don't fail in src/Configure with "string too
5500 long" errors when generating the MODULES entry for src/Makefile
5501 [Ben Hyde, Ralf S. Engelschall]
5503 *) Make sure src/Configure doesn't complain about the old directory
5504 /usr/local/etc/httpd/ when APACI is used. [Lars Eilebrecht]
5506 Changes with Apache 1.3b6
5508 *) PORT: Clean up warnings on Ultrix and HPUX. [Ben Hyde]
5510 *) Adding DSO support for the HP/UX platform by emulating the dlopen-style
5511 interface via the similar but proprietary HP/UX shl_xxx-style system
5512 calls. [Ralf S. Engelschall]
5514 *) PORT: Updated UnixWare 2.0.x and 2.1.x entries for DSO support and made
5515 APACI Makefile.tmpl "install" target more robust for sensible UnixWare
5516 Make. [Ralf S. Engelschall]
5518 *) ++++ THE BIG SYMBOL RENAMING ++++
5519 To avoid symbol clashes with third-party code compiled into the server,
5520 we globally applied the prefix "ap_" to the following classes of
5522 - Apache provided general functions (e.g., ap_cpystrn)
5523 - Public API functions (e.g., palloc, bgets)
5524 - Private functions which we can't make static (because of
5525 cross-object usage) but should be (e.g., new_connection)
5526 For backward source compatibility a new header file named compat.h was
5527 created which provides defines for the old symbol names and can be used
5528 by third-party module authors.
5531 *) Added dynamic shared object (DSO) support for SVR4-derivates: The
5532 problem under SVR4 is that there is no command flag to force the linker
5533 to export the global symbols of the httpd executable therewith they are
5534 available to the DSO's. Instead of problematic hacks like creating a
5535 dummy.so file (containing dummy references to all global symbols) the
5536 httpd binary is linked against, we use a clean trick stolen from Perl 5:
5537 Placing the Apache core code itself into a DSO library named libhttpd.so.
5538 This way the global symbols _HAVE_ to be exported and thus are available
5539 to any manually loaded DSO's under runtime. To reduce the impact to the
5540 user to null we go even further and create a stub httpd executable which
5541 automatically keeps track of the DSO library loading itself and thus
5542 hides the complete mechanism from the user. Although the generation of
5543 this DSO library is automatically triggered for platforms which
5544 essentially need it (mostly all SVR4-derivates) it can be also enabled
5545 manually via the Rule SHARED_CORE. This can be interesting in the future
5546 where we perhaps exploit this libhttpd.so mechanism for providing nifty
5547 features like graceful upgrades, or whatever.
5548 [Ralf S. Engelschall, Martin Kraemer]
5550 *) Build the libraries before building the rest of the tools. [Ben Hyde]
5552 *) Add "distclean" target to src/-Makefiles to provide "make distclean" also
5553 inside the src subtree (i.e. for non-APACI users). Following GNU Makefile
5554 conventions while "clean" removes only stuff created by "all" targets,
5555 "distclean" additionally removes the stuff from the configuration
5556 process. This way "make distclean" (hence the name) provides a fresh
5557 source tree as it was for distribution.
5558 [Ralf S. Engelschall]
5560 *) Allow top-level (APACI) Makefile to break on build errors
5561 the same way the src/ subtree Makefiles breaks on them by replacing the
5562 initial APACI sed-subdir-display-kludge with a more clean
5563 variable-passing-solution: variable SDP can optionally hold the subdir
5564 prefix which is consistently used for displaying the subdir movement.
5565 This way even the top-level Makefile can stop correctly on errors as the
5566 user expects. [Ralf S. Engelschall]
5568 *) Fixed ordering of argument checks for RewriteBase directive.
5569 [Todd Eigenschink <eigenstr@mixi.net>] PR#2045
5571 *) Change Win32 IS_MODULE to SHARED_MODULE to match Unix' method of
5572 indicating that a module is being compiled for dynamic loading. Also
5573 remove #define IS_MODULE from modules and add SHARED_MODULE define
5574 to the mak/dsp files. [Alexei Kosut]
5576 *) Reduce logging level of "normal" warning messages to APLOG_INFO,
5577 since we are now logging APLOG_WARNING by default. [Roy Fielding]
5579 *) PORT: OS/2 tweak to deal with multiple .exe targets. [Brian Havard]
5581 *) Add documentation file and src/Configuration.tmpl entry for the
5582 experimental mod_mmap_static module. Because although it is and marked as
5583 an experimental one it is distributed and thus should be documented and
5584 prepared for configuration the same way as all others modules.
5585 [Ralf S. Engelschall]
5587 *) Add query (-q) option to apxs support tool to be able to manually query
5588 specific settings from apxs. This is needed for instance when you
5589 manually want to access Apache's header files and you need to assemble
5590 the -I option. Now you can do -I`apxs -q INCLUDEDIR`.
5591 [Ralf S. Engelschall]
5593 *) Now src/Configure uses a fallback strategy for the shared object support
5594 on platforms where no explicit information is available: If a Perl
5595 installation exists we ask it about its shared object support and if it's
5596 the dlopen-style one we shamelessly guess the compiler and linker flags
5597 for creating shared objects from Perls knowledge. Of course, the user is
5598 warning about what we are doing and informed that he should send us
5599 the guessed flags when they work. [Ralf S. Engelschall]
5601 *) Provide APACI --without-support option to be able to disable the build
5602 and installation of the support tools from the src/support/ area.
5603 Although its useful to have these installed per default we should provide
5604 a way to compile and install without them for backward-compatibility.
5605 [Ralf S. Engelschall]
5607 *) Add of the new APache eXtenSion (apxs) support tool for building and
5608 installing modules into an _already installed_ Apache package through the
5609 dynamic shared object (DSO) mechanism [mod_so.c]. The trick here is that
5610 this approach actually doesn't need the Apache source tree. The
5611 (APACI-installed) server package is enough, because this now includes the
5612 Apache C header files (PREFIX/include) and the new APXS tool
5613 (SBINDIR/apxs). The intend is to provide a handy tool for third-party
5614 module authors to build their Apache modules _OUTSIDE_ the Apache source
5615 tree while avoiding them to fiddle around with the totally platform
5616 dependend way of compiling DSO files. The tool supports all ranges of
5617 modules, from trivial ones (single mod_foo.c) to complex ones (like PHP3
5618 which has a mod_php3.c plus a pre-built libmodphp3-so.a) and even can
5619 on-the-fly generate a minimalistic Makefile and sample module for the
5620 first step to provide both a quick success event and to demonstrate the
5621 APXS mechanism to module authors. [Ralf S. Engelschall]
5623 *) Fix core dumps in use of CONNECT in proxy.
5624 [Rainer.Scherg@rexroth.de] PR#1326, #1573, #1942
5626 *) Modify the log directives in httpd.conf-dist files to use CustomLog
5627 so that users have examples of how CustomLog can be used.
5630 *) Add the new Apache Autoconf-style Interface (APACI) for the top-level of
5631 the Apache distribution tree. Until Apache 1.3 there was no real
5632 out-of-the-box batch-capable build and installation procedure for the
5633 complete Apache package. This is now provided by a top-level "configure"
5634 script and a corresponding top-level "Makefile.tmpl" file. The goal is
5635 to provide a GNU Autoconf-style frontend which is capable to both drive
5636 the old src/Configure stuff in batch and additionally installs the
5637 package with a GNU-conforming directory layout. Any options from the old
5638 configuration scheme are available plus a lot of new options for flexibly
5639 customizing Apache. [Ralf S. Engelschall]
5641 *) The floating point ap_snprintf code wasn't threadsafe.
5642 Had to remove the HAVE_CVT macro in order to do threadsafe
5643 calling of the ?cvt() floating point routines. [Dean Gaudet]
5645 *) PORT: Add the SCO_SV port. [Jim Jagielski] PR#1962
5647 *) PORT: IRIX needs the -n32 flag iff using the 'cc' compiler
5648 [Jim Jagielski] PR#1901
5650 *) BUG: Configure was using TCC and CC inconsistently. Make sure
5651 Configure knows which CC we are using. [Jim Jagielski]
5653 *) "Options +Includes" wasn't correctly merged if "+IncludesNoExec"
5654 was defined in a parent directory. [Lars Eilebrecht]
5656 *) API: ap_snprintf() code mutated into ap_vformatter(), which is
5657 a generic printf-style routine that can call arbitrary output
5658 routines. Use this to replace http_bprintf.c. Add new routines
5659 psprintf(), pvsprintf() which allocate the exact amount of memory
5660 required for a string from a pool. Use psprintf() to clean up
5661 various bits of code which used ap_snprintf()/pstrdup().
5664 *) PORT: HAVE_SNPRINTF doesn't do anything any longer. This is because
5665 ap_snprintf() has different semantics and formatting codes than
5666 snprintf(). [Dean Gaudet]
5668 *) SIGXCPU and SIGXFSZ are now reset to SIG_DFL at boot-time. This
5669 is necessary on at least Solaris where the /etc/rc?.d scripts
5670 are run with these signals ignored, and "SIG_IGN" settings are
5671 maintained across exec().
5672 [Rein Tollevik <reint@sys.sol.no>] PR#2009
5674 *) Fix the check for symbolic links in ``RewriteCond ... -l'': stat() was
5675 used instead of lstat() and thus this flag didn't work as expected.
5676 [Rein Tollevik <reint@sys.sol.no>] PR#2010
5678 *) Fix the proxy pass-through feature of mod_rewrite for the case of
5679 existing QUERY_STRING now that mod_proxy was recently changed because of
5680 the new URL parsing stuff. [Ralf S. Engelschall]
5682 *) A few changes to scoreboard definitions which helps gcc generate
5683 better code. [Dean Gaudet]
5685 *) ANSI C doesn't guarantee that "int foo : 2" in a structure will
5686 be a signed bitfield. So mark a few bitfields as signed to
5687 ensure correct code. [Dean Gaudet]
5689 *) The default for HostnameLookups was changed to Off, but there
5690 was a problem and it wasn't taking effect. [Dean Gaudet]
5692 *) PORT: Clean up undefined signals on some platforms (SCO, BeOS).
5695 *) After a SIGHUP the listening sockets in the parent weren't
5696 properly marked for closure on fork().
5697 [Jürgen Keil <jk@tools.de>] PR#2000
5699 *) Allow %2F in two situations: 1) it is in the query part of the URI,
5700 therefore not exposed to %2F -> '/' translations and 2) the request
5701 is a proxy request, so we're not dealing with a local resource anyway.
5702 Without this, the proxy would fail to work for any URL's with
5703 %2f in them (occurs quite often in
5704 http://.../cgi-bin/...?http%3A%2F%2F... references) [Martin Kraemer]
5706 *) Protect against FD_SETSIZE mismatches. [Dean Gaudet]
5708 *) Make the shared object compilation command more portable by avoiding
5709 the direct combination of `-c' & `-o' which is not honored by some
5710 compilers like UnixWare's cc. [Ralf S. Engelschall]
5712 *) WIN32: the proxy was creating filenames missing the last four
5713 characters. While this normally doesn't stop anything from
5714 working, it can result in extra collisions.
5715 [Tim Costello <tjcostel@socs.uts.edu.au>] PR#1890
5717 *) Now mod_proxy uses the response string (in addition to the response status
5718 code) from the already used FTP SIZE command to setup the Content-Length
5719 header if available. [Ralf S. Engelschall] PR#1183
5721 *) Reanimated the (still undocumented) proxy receive buffer size directive:
5722 Renamed from ReceiveBufferSize to ProxyReceiveBufferSize because the old
5723 name was really too generic, added documentation for this directive to
5724 the mod_proxy.html and corrected the hyperlink to it in the
5725 new_features_1.3.html document. [Ralf S. Engelschall] PR#1348
5727 *) Fix a bug in the src/helpers/fp2rp script and make it a little bit
5728 faster [Martin Kraemer]
5730 *) Make Configure die when you give it an unknown command switch.
5733 *) Add five new and fresh manpages for the support programs: dbmmanage.1,
5734 suexec.8, htdigest.1, rotatelogs.8 and logresolve.8. Now all up-to-date
5735 and per default compiled support programs have manual pages - just to
5736 document our stuff a little bit more and to be able to do really
5737 Unix-like installations ;-) [Ralf S. Engelschall]
5739 *) Major cleanups to the Configure script to make it and its generated
5740 Makefiles again readable and maintainable: add SRCDIR option, removed
5741 INCLUDES_DEPTH[0-2] kludge, cleanup of TARGET option, cleanup of
5742 generated sections, consequently added Makefile headers with inheritance
5743 information, added subdir movement messages for easier following where
5744 the build process currently stays (more verbose then standard Make, less
5745 verbose than GNU make), same style to comments in the Configure script,
5746 added Apache license header, fixed a few bugs, etc. [Ralf S. Engelschall]
5748 *) Add the new ApacheBench program "ab" to src/support/: This is derived
5749 from the ZeusBench benchmarking program and can be used to determine the
5750 response performance of an Apache installation. This version is
5751 officially licensed with Zeus Technology, Ltd. See the license agreement
5752 statements in <199803171224.NAA24547@en1.engelschall.com> in apache-core.
5753 [Ralf S. Engelschall]
5755 *) API: Various core functions that are definately not part of the API
5756 have been made static, and a few have been marked API_EXPORT. Still
5757 more have been marked CORE_EXPORT and are not intended for general
5758 use by modules. [Doug MacEachern, Dean Gaudet]
5760 *) mod_proxy was not clearing the Proxy-Connection header from
5761 requests; now it does. This did not violate any spec, however
5762 causes poor interactions when you are talking to remote proxies.
5763 [Marc Slemko] PR#1741
5765 *) Various cleanups to the command line interface and manual pages.
5766 [Ralf S. Engelschall]
5768 *) cfg_getline() was not properly handling lines that did not end
5769 with a line termination character. [Marc Slemko] PR#1869, 1909
5771 *) Performance tweak to mod_log_config. [Dmitry Khrustalev]
5773 *) Clean up some undocumented behavior of mod_setenvif related to
5774 "merging" two SetEnvIf directives when they match the same header
5775 and regex. Document that mod_setenvif will perform comparisons in
5776 the order they appear in the config file. Optimize mod_setenvif by
5777 doing more work at config time rather than at runtime.
5780 *) src/include/ap_config.h now wraps it's #define's with #ifndef/#endif's
5781 to allow for modules to overrule them and to reduce redefinition
5782 warnings [Jim Jagielski]
5784 *) [PORT] For A/UX change the OS-#define for -DAUX to -DAUX3.
5787 *) Making the hard-coded cross-module function call mime_find_ct() (from
5788 mod_proxy to mod_mime) obsolete by making sure the API hook for MIME type
5789 checking is really called even for proxy requests except for URLs with
5790 HTTP schemes (because there we can optimize by not running the type
5791 checking hooks due to the fact that the proxy gets the MIME Content-type
5792 from the remote host later). This change cleans up mod_mime by removing
5793 the ugly export kludge, makes the one-liner file mod_mime.h obsolete, and
5794 especially unbundles mod_proxy and mod_mime. This way they both now can
5795 be compiled as shared objects and are no longer tied together.
5796 [Ralf S. Engelschall]
5798 *) util.c cleanup and speedup. [Dean Gaudet]
5800 *) API: Clarification, pstrndup() will always copy n bytes of the source
5801 and NUL terminate at the (n+1)st byte. [Dean Gaudet]
5803 *) Mark module command_rec and handler_rec structures const so that they
5804 end up in the read-only data section (and are friendlier to systems
5805 that don't do optimistic memory allocation on fork()). [Dean Gaudet]
5807 *) Add check to the "Port" directive to make sure the specified
5808 port is in the appropriate range. [Ben Hyde]
5810 *) Performance improvements to invoke_handler().
5811 [Dmitry Khrustalev <dima@bog.msu.su>]
5813 *) Added support for building shared objects even for library-style modules
5814 (which are built from more than one object file). This now provides the
5815 ability to build mod_proxy as a shared object module. Additionally
5816 modules like mod_example are now also supported for shared object
5817 building because the generated Makefiles now no longer assume there is at
5818 least one statically linked module. [Ralf S. Engelschall]
5820 *) API: Clarify usage of content_type, handler, content_encoding,
5821 content_language and content_languages fields in request_rec. They
5822 must always be lowercased; and the strings pointed to shouldn't
5823 be modified (you must copy them to modify them). Fix a few bugs
5824 related to this. [Dean Gaudet]
5826 *) API: Clarification: except for RAW_ARGS, all command handlers can
5827 treat the char * parameters as permanent, and modifiable. There
5828 is no need to pstrdup() them. Clean up some needless pstrdup().
5831 *) Now mod_so keeps track of which module shared objects with which names
5832 are loaded and thus avoids multiple loading and unloading and irritating
5833 error_log messages. [Ralf S. Engelschall]
5835 *) Prior to the existence of mod_setenv it was necessary to tweak the TZ
5836 environment variable in the apache core. But that tweaking interferes
5837 with mod_setenv. So don't tweak if the user has specified an explicit
5838 TZ variable. [Jay Soffian <jay@cimedia.com>] PR#1888
5840 *) rputs() did not calculate r->sent_bodyct properly.
5841 [Siegmund Stirnweiss <siegst@kat.ina.de>] PR#1900
5843 *) The CGI spec says that REMOTE_HOST should be set to the remote hosts's
5844 name, or left unset if this value is unavailable. Apache was setting
5845 it to the IP address when unavailable.
5846 [Tony Finch <fanf@demon.net>] PR#1925
5848 *) Various improvements to the configuration and build support for compiling
5849 modules as shared objects. Especially Solaris 2.x, SunOS 4.1, IRIX and
5850 OSF1 support with GCC and vendor compilers was added. This way shared
5851 object support is now provided out-of-the-box for FreeBSD, Linux,
5852 Solaris, SunOS, IRIX and OSF1. In short: On all major platforms!
5853 [Ralf S. Engelschall]
5855 *) Minor cleanup in http_main -- split QNX and OS2 specific "mmap"
5856 scoreboard code into separate #defines -- USE_POSIX_SCOREBOARD
5857 and USE_OS2_SCOREBOARD. [Dean Gaudet]
5859 *) Fix one more special locking problem for RewriteMap programs in
5860 mod_rewrite: According to the documentation of flock(), "Locks are on
5861 files, not file descriptors. That is, file descriptors duplicated
5862 through dup(2) or fork(2) do not result in multiple instances of a lock,
5863 but rather multiple references to a single lock. If a process holding a
5864 lock on a file forks and the child explicitly unlocks the file, the
5865 parent will lose its lock.". To overcome this we have to make sure the
5866 RewriteLock file is opened _AFTER_ the childs were spawned which is now
5867 the case by opening it in the child_init instead of the module_init API
5868 hook. [Ralf S. Engelschall] PR#1029
5870 *) Change to Location and LocationMatch semantics. LocationMatch no
5871 longer lets a single slash match multiple adjacent slashes in the
5872 URL. This change is for consistency with RewriteRule and
5873 AliasMatch. Multiple slashes have meaning in URLs that they do
5874 not have in (some) filesystems. Location on the other hand can
5875 be considered a shorthand for a more complicated regex, and it
5876 does match multiple slashes with a single slash -- which is
5877 also consistent with the Alias directive.

5884 *) The Configure script now generates src/include/ap_config.h which
5885 contains the set of defines used when Apache is compiled on a platform.
5886 This file can then be included by external modules before including
5887 any Apache header files in case they are being built separately from
5888 Apache. Along with this change, a couple of minor changes were
5889 made to make Apache's #defines coexist peacefully with any autoconf
5890 defines an external module might have. [Rasmus Lerdorf]
5892 *) Fix mod_rewrite for the ugly API case where <VirtualHost> sections exist
5893 but without any RewriteXXXXX directives. Here mod_rewrite is given no
5894 chance by the API to initialize its per-server configuration and thus
5895 receives the wrong one from the main server. This is now avoided by
5896 remembering the server together with the config structure while
5897 configuring and later assuming there is no config when we see a
5898 difference between the remembered server and the one calling us.
5899 [Ralf S. Engelschall] PR#1790
5901 *) Fixed the DBM RewriteMap support for mod_rewrite: First the support now
5902 is automatically disabled under configure time when the dbm_xxx functions
5903 are not available. Second, two heavy source code errors in the DBM
5904 support code were fixed. This makes DBM RewriteMap's usable again after
5905 a long time of brokenness. [Ralf S. Engelschall] PR#1696
5907 *) Now all configuration files support Unix-style line-continuation via
5908 the trailing backslash ("\") character. This enables us to write down
5909 complex or just very long directives in a more readable way. The
5910 backslash character has to be really the last character before the
5911 newline and it has not been prefixed by another (escaping) backslash.

5914 *) When using ProxyPass the ?querystring was not passed correctly.
5915 [Joel Truher <truher@wired.com>]
5917 *) To deal with modules being compiled and [dynamically] linked
5918 at a different time from the core, the SERVER_VERSION and
5919 SERVER_BUILT symbols have been abstracted through the new
5920 API routines apapi_get_server_version() and apapi_get_server_built().
5923 *) WIN32: Preserve trailing slash in canonical path (and hence
5924 in PATH_INFO). [Paul Sutton, Ben Laurie]
5926 *) PORT: USE_PTHREAD_SERIALIZED_ACCEPT has proven unreliable
5927 depending on the rev of Solaris and what mixture of modules
5928 are in use. So it has been disabled, and Solaris is back to
5929 using USE_FCNTL_SERIALIZED_ACCEPT. Users may experiment with
5930 USE_PTHREAD_SERIALIZED_ACCEPT at their own risk, it may speed
5931 up static content only servers. Or it may fail unpredictably.
5932 [Dean Gaudet] PR#1779, 1854, 1904
5934 *) mod_test_util_uri.c created which tests the logic in util_uri.c.
5937 *) API: Rewrite of absoluteURI handling, and in particular how
5938 absoluteURIs match vhosts. Unless a request is a proxy request, a
5939 "http://host" url is treated as if a similar "Host:" header had been
5940 supplied. This change was made to support future HTTP/1.x protocols
5941 which may require clients to send absoluteURIs for all requests.
5943 In order to achieve this change subtle changes were made to the API. In a
5944 request_rec, r->hostlen has been removed. r->unparsed_uri now exists so
5945 that the unmodified uri can be retrieved easily. r->proxyreq is not set
5946 by the core, modules must set it during the post_read_request or
5947 translate_names phase.
5949 Plus changes to the virtualhost test suite for absoluteURI testing.
5951 This fixes several bugs with the proxy proxying requests to vhosts
5952 managed by the same httpd.
5955 *) API: Cleanup of code in http_vhost.c, and remove vhost matching
5956 code from mod_rewrite. The vhost matching is now performed by a
5957 globally available function matches_request_vhost(). [Dean Gaudet]
5959 *) Reduce memory usage, and speed up ServerAlias support. As a

5970 *) Add the `%a' construct to LogFormat and CustomLog to log the client IP
5971 address. [Todd Eigenschink <eigenstr@mixi.net>] PR#1885
5973 *) API: A new source module main/util_uri.c; It contains a routine
5974 parse_uri_components() and friends which breaks a URI into its component
5975 parts. These parts are stored in a uri_components structure called
5976 parsed_uri within each request_rec, and are available to all modules.
5977 Additionally, an unparse routine is supplied which re-assembles the URI
5978 components back to an URI, optionally hiding the username:password@ part
5979 from ftp proxy requests, and other useful routines. Within the structure,
5980 you find on a ready-for-use basis:
5981 scheme; /* scheme ("http"/"ftp"/...) */
5982 hostinfo; /* combined [user[:password]@]host[:port] */
5983 user; /* user name, as in http://user:passwd@host:port/ */
5984 password; /* password, as in http://user:passwd@host:port/ */
5985 hostname; /* hostname from URI (or from Host: header) */
5986 port_str; /* port string (integer representation is in "port") */
5987 path; /* the request path (or "/" if only scheme://host was given) */
5988 query; /* Everything after a '?' in the path, if present */
5989 fragment; /* Trailing "#fragment" string, if present */
5990 This is meant to serve as the platform for *BIG* savings in
5991 code complexity for the proxy module (and maybe the vhost logic).
5994 *) Make all possible meta-construct expansions ($N, %N, %{NAME} and
5995 ${map:key}) available for all location where a string is created in
5996 mod_rewrite rewriting rulesets: 1st arg of RewriteCond, 2nd arg of
5997 RewriteRule and for the [E=NAME:STRING] flag of RewriteRule. This way the
5998 possible expansions are consequently usable at all string creation
5999 locations. [Ralf S. Engelschall]
6001 *) Fix initialization of RewriteLogLevel (default now is 0 as documented
6002 and not 1) and the per-virtual-server merging of directives. Now all
6003 directives except `RewriteEngine' and `RewriteOption' are either
6004 completely overridden (default) or completely inherited (when
6005 `RewriteOptions inherit') is used. [Ralf S. Engelschall] PR#1325

6011 *) Fix bug introduced in 1.3b4-dev, config with no Port setting would cause
6012 server to bind to port 0 rather than 80. [Dean Gaudet]
6014 *) Fix long-standing problem with RewriteMap _programs_ under Unix derivates
6015 (like SunOS and FreeBSD) which don't accept the locking of pipes
6016 directly. A new directive RewriteLock is introduced which can be used to
6017 setup a separate locking file which then is used for synchronization.

6032 *) The mod_setenvif BrowserMatch backwards compatibility command did not
6033 work properly with spaces in the regex. [Ronald Tschalaer] PR#1825
6035 *) Add new RewriteMap types: First, `rnd' which is equivalent to the `txt'
6036 type but with a special post-processing for the looked-up value: It
6037 parses it into alternatives according to `|' chars and then only one
6038 particular alternative is chosen randomly (this is an essential
6039 functionality needed for balancing between backend-servers when using
6040 Apache as a Reverse Proxy. The looked up value here is a list of
6041 servers). Second, `int' with the built-in maps named `tolower' and
6042 `toupper' which can be used to map URL parts to a fixed case (this is an
6043 essential feature to fix the case of server names when doing mass
6044 virtual-hosting with the help of mod_rewrite instead of using
6045 <VirtualHost> sections). [Ralf S. Engelschall, parts based on code from
6046 Jay Soffian <jay@cimedia.com>] PR#1631
6048 *) Add a new directive to mod_proxy similar to ProxyPass: `ProxyPassReverse'.
6049 This directive lets Apache adjust the URL in Location-headers on HTTP
6050 redirect responses sent by the remote server. This way the virtually
6051 mapped area is no longer left on redirects and thus by-passed which is
6052 especially essential when running Apache as a reverse proxy.

6168 preserves the encoding the client requests (for example if
6169 it requests x-gzip, then Apache will respond with x-gzip
6170 in the Content-Encoding header).

6200 *) Yet another rearrangement of the source tree.. now all the common
6201 header files are in the src/include directory. The -Imain -Iap
6202 references in Makefiles have been changed to the simpler -Iinclude
6203 instead. In addition to simplifying the build a little bit, this
6204 also makes it clear when a module is referencing something in a
6205 other than kosher manner (e.g., the proxy including mod_mime.h).
6206 Module-private header files (the proxy, mod_mime, the regex library,
6207 and mod_rewrite) have not been moved to src/include; nor have
6208 the OS-abstraction files. [Ken Coar]

6220 server setting inside vhosts (only an issue when you have no
6221 <Directory> or other section containing an Options that affects
6222 a request). Options +foo or -foo in the main_server wouldn't

6237 *) mod_unique_id was erroneously generating a second unique id when
6238 an internal redirect occured. Such redirects occur, for example,
6239 when processing a DirectoryIndex match. [Dean Gaudet]
6241 *) API: table_add, table_merge, and table_set include implicit pstrdup()
6242 of the key and value. But in many cases this is not required
6243 because the key/value is a constant, or the value has been built
6244 by pstrcat() or other similar means. New routines table_addn,
6245 table_mergen, and table_setn have been added to the API, these
6246 routines do not pstrdup() their arguments. The core code and
6247 standard modules were changed to take advantage of these routines.
6248 The resulting server is up to 20% faster in some situations.
6250 Note that it is easy to get code subtly wrong if you pass a key/value
6251 which is in a pool other than the pool of the table. The only
6252 safe thing to do is to pass key/values which are in the pool of
6253 the table, or in one of the ancestors of the pool of the table.
6254 i.e. if the table is part of a subrequest, a value from the main
6255 request's pool is OK since the subrequest pool is a sub_pool of the
6256 main request's pool (and therefore has a lifespan at most as long as
6257 the main pool). There is debugging code which can detect improper
6258 usage, enabled by defining POOL_DEBUG. See alloc.c for more details.
6259 [Dmitry Khrustalev <dima@bog.msu.su>, Dean Gaudet]
6261 *) More mod_mime_magic cleanup: fewer syscalls; should handle "files"
6262 which don't exist on disk more gracefully; handles vhosts properly.
6263 Update documentation to reflect the code -- if there's no
6264 MimeMagicFile directive then the module is not enabled.
6267 *) PORT: Some older *nix dialects cannot automatically start scripts
6268 which begin with a #! interpreter line (the shell starts the scripts
6269 appropriately on these platforms). Apache now supports starting of
6270 "hashbang-scripts" when the NEED_HASHBANG_EMUL define is set.

6274 *) API: "typedef array_header table" removed from alloc.h, folks should
6275 have been writing to use table as if it were an opaque type, but even
6276 some standard modules got this wrong. By changing the definition
6277 to "typedef struct table table" module authors will receive compile
6278 time warnings that they're doing the wrong thing. This change
6279 facilitates future changes with more sophisticated table
6280 structures. Specifically, module authors should be using table_elts()
6281 to get access to an array_header * for the table. [Dean Gaudet]
6283 *) API: Renamed new_connection() to avoid namespace collision with LDAP
6284 library routines. [Ken Coar, Rasmus Lerdorf]
6286 *) WIN32: mod_speling is now available on the Win32 platform.
6289 *) For clarity the following compile time definition was changed:
6291 SAFE_UNSERIALIZED_ACCEPT -> SINGLE_LISTEN_UNSERIALIZED_ACCEPT
6293 Also, for example, HAVE_MMAP would mean to use mmap() scoreboards
6294 and not be a general notice that the OS has mmap(). Now the
6295 HAVE_MMAP/SHMGET #defines strictly are informational that the
6296 OS has that method of shared memory; the type to use for
6297 the scoreboard is a seperate #define (USE_MMAP_SCOREBOARD
6298 and USE_SHMGET_SCOREBOARD). This allows outside modules to
6299 determine if shared memory is available and allows Apache
6300 to determine the best method to use for the scoreboard.

6389 *) "basic" auth needs a case-insensitive comparison.
6390 [Ronald.Tschalaer@psi.ch] PR#1666
6392 *) For maximum portability, the environment passed to CGIs should
6393 only contain variables whose names match the regex
6394 /[a-zA-Z][a-zA-Z0-9_]*/. This is now enforced by stamping
6395 underscores over any character outside the regex. This
6396 affects HTTP_* variables, in a way that should be backward
6397 compatible for all the standard headers; and affects variables
6398 set with SetEnv/BrowserMatch and similar directives.
6401 *) mod_speling returned incorrect HREF's when an ambigous match

6434 possible buffer overflows and a possible infinite loop.
6435 [Dean Gaudet, Marc Slemko]
6437 *) SECURITY: Numerous changes to mod_imap in a general cleanup
6438 including fixing a possible buffer overflow. [Dean Gaudet]
6440 *) WIN32: overhaul of multithreading code. Shutdowns are now graceful
6441 (connections are not dropped). Code can handle graceful restarts
6442 (but there is as yet no way to signal this to Apache). Various
6443 other cleanups. [Paul Sutton]
6445 *) The aplog_error changes specific to 1.3 introduced a buffer
6446 overrun in the (now legacy) log_printf function. Fixed.
6449 *) mod_digest didn't properly deal with proxy authentication. It
6450 also lacked a case-insensitive comparision of the "Digest"

6485 [Ben Reser <breser@regnow.com>] PR#1366
6487 *) The bputc() macro was not properly integrated with the chunking
6488 code; in many cases modules using bputc() could cause completely
6489 bogus chunked output. (Typically this will show up as problems
6490 with Internet Explorer 4.0 reading a page, but other browsers
6491 having no problem.) [Dean Gaudet]
6493 *) Create LARGE_WRITE_THRESHOLD define which determines how many
6494 bytes have to be supplied to bwrite() before it will consider
6495 doing a writev() to assemble multiple buffers in one system
6496 call. This is critical for modules such as mod_include,
6497 mod_autoindex, mod_php3 which all use bputc()/bputs() of smaller
6498 strings in some cases. The result would be extra effort
6499 setting up writev(), and in many cases extra effort building
6500 chunks. The default is 31, it can be overriden at compile
6503 *) Move the gid switching code into the child so that log files

6515 *) ap_slack() moved out of main/util.c into ap/ap_slack.c as part of
6516 the libap consolidation work. [Ken Coar]

6610 This turns out to be a bug in Winsock - select() doesn't always

6613 *) Directives owned by http_core can now use the new check_cmd_context()
6614 routine to ensure that they're not being used within a container
6615 (e.g., <Directory>) where they're invalid. [Martin Kraemer]
6617 *) PORT: Recent changes made it necessary to add explicit prototype
6618 for fgetc() and fgets() on SunOS 4.x. [Martin Kraemer, Ben Hyde]
6620 *) It was necessary to distinguish between resources which are
6621 allocated in the parent, for cleanup in the parent, and resources
6622 which are allocated in each child, for cleanup in each child.
6623 A new pool was created which is passed to the module child_init
6624 and child_exit functions; modules are free to register per-child
6625 cleanups there. This fixes a bug with reliable piped logs.
6628 *) mod_autoindex wasn't displaying the ReadmeName file at the bottom
6629 unless it was also doing FancyIndexes, but it displayed the
6630 HeaderName file at the top under all circumstances. It now shows
6631 the ReadmeName file for simple indices, too, as it should.
6634 *) http_core was mmap()ing even in cases where it wasn't going to
6635 read the file. [Ben Hyde <bhyde@gensym.com>]
6637 *) Complete rewrite ;-) of mod_rewrite's URL rewriting engine:
6638 Now the rewriting engine (the heart of mod_rewrite) is organized more
6639 straight-forward, first time well documented and reduced to the really
6640 essential parts. All redundant cases were stripped off and processing now
6641 is the same for both per-server and per-directory context with only a
6642 minimum difference (the prefix stripping in per-dir context). As a
6643 side-effect some subtle restrictions and two recently discovered problems
6644 are gone: Wrong escaping of QUERY_STRING on redirects in per-directory
6645 context and restrictions on the substitution URL on redirects.
6646 Additionally some minor source cleanups were done.

6803 *) TestCompile was not passing $LIBS [Dean Gaudet]
6805 *) Makefile.tmpl was not using $CFLAGS in the link phase.
6808 *) Add debugging code to alloc.c. Defining ALLOC_DEBUG provides a
6809 rudimentary memory debugger which can be used on live servers with
6810 low impact -- it sets all allocated and freed memory bytes to 0xa5.
6811 Defining ALLOC_USE_MALLOC will cause the alloc code to use malloc()
6812 and free() for each object. This is far more expensive and should
6813 only be used for testing with tools such as Electric Fence and
6814 Purify. See main/alloc.c for more details. [Dean Gaudet]
6816 *) Configure uses a sh trap and didn't set its exitcode properly.
6817 [Dean Gaudet] PR#1159
6819 *) Yet another vhost revamp. Add the NameVirtualHost directive which
6820 explicitly lists the ip:port pairs that are to be used for name-vhosts.
6821 From a given ip:port, regardless what the Host: header is, you can
6822 only reach the vhosts defined on that ip:port. The precedence of
6823 vhosts was reversed to match other precedences in the config --
6824 the earlier vhosts override the later vhosts. All vhost matching was
6825 moved into http_vhost.[ch]. [Dean Gaudet]
6827 *) ap_inline can be used to force inlining. GNUC __attribute__() can
6828 be used for whatever reason is appropriate (i.e. format() warnings
6829 for printf style functions). Both are enabled only with
6830 gcc >= 2.7.x (so that we have fewer support issues with older
6831 versions). [Dean Gaudet]
6833 *) Fix support for Proxy Authentication (we were testing the response
6834 status too early). [Marc Slemko]

6843 *) When booting, apache will now detach itself from stdin, stdout,
6844 and stderr. stderr will not be detached until after the config
6845 files have been read so you will be able to see initial error
6846 messages. After that all errors are logged in the error_log.
6847 This makes it more convenient to start apache via rsh, ssh,
6848 or crontabs. [Dean Gaudet] PR#523
6850 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.

6864 *) mod_autoindex improperly counted &escapes; as more than one
6865 character in the description. It also improperly truncated
6866 descriptions that were exactly the maximum length.
6869 *) RedirectMatch was not properly escaping the result (PR#1155). Also
6870 "RedirectMatch /advertiser/(.*) $1" is now permitted.
6873 *) mod_include now uses symbolic names to check for request success
6874 and return HTTP errors, and correctly handles all types of
6875 redirections (previously it only did temporary redirect correctly).
6876 [Ken Coar, Roy Fielding]
6878 *) mod_userdir was modifying r->finfo in cases where it wasn't setting

6895 *) If BUFFERED_LOGS is defined then mod_log_config will do atomic
6896 buffered writes -- that is, it will buffer up to PIPE_BUF (i.e. 4k)
6897 bytes before writing, but it will never split a log entry across a
6898 buffer boundary. [Dean Gaudet]
6900 *) API: the short_score record has been split into two pieces, one which
6901 the parent writes on, and one which the child writes on. As part of
6902 this change the get_scoreboard_info() function was removed, and
6903 scoreboard_image was exported. This change fixes a race condition
6904 in file based scoreboard systems, and speeds up changes involving the
6905 scoreboard in earlier 1.3 development. [Dean Gaudet]
6907 *) API: New register_other_child() API (see http_main.h) which allows
6908 modules to register children with the parent for maintenance. It
6909 is disabled by defining NO_OTHER_CHILD. [Dean Gaudet]
6911 *) API: New piped_log API (see http_log.h) which implements piped logs,
6912 and will use register_other_child to implement reliable piped logs
6913 when it is available. The reliable piped logs part can be disabled
6914 by defining NO_RELIABLE_PIPED_LOGS. At the moment reliable piped
6915 logs is only available on Unix. [Dean Gaudet]
6917 *) API: set_last_modified() broken into set_last_modified(), set_etag(), and
6918 meets_conditions(). This allows conditional HTTP selection to be
6919 handled separately from the storing of the header fields, and provides
6920 the ability for CGIs to set their own ETags for conditional checking.
6921 [Ken Coar, Roy Fielding] PR#895
6923 *) Changes to mod_log_config to allow naming of format strings.
6924 Format nicknames are defined with "LogFormat fmt nickname", and can
6925 be used with "LogFormat nickname" and "CustomLog logtarget nickname".
6928 *) New module, "mod_speling", which can help find files even when
6929 the URL is slightly misspelled. [Martin Kraemer, Alexei Kosut]
6931 *) API: New function child_terminate() triggers the child process to
6932 exit, while allowing the child finish what it needs to for the
6933 current request first.
6934 [Doug MacEachern, Alexei Kosut]
6936 *) Windows now defaults to using full status reports with mod_status.
6937 [Alexei Kosut] PR #1094
6939 *) *Really* disable all mod_rewrite operations if the engine is off.
6940 Some things (like RewriteMaps) were checked/performed even if they
6941 weren't supposed to be. [Ken Coar] PR #991
6943 *) Implement a new timer scheme which eliminates the need to call alarm() all
6944 the time. Instead a counter in the scoreboard for each child is used to
6945 show when the child has made forward progress. The parent samples this
6946 counter every scoreboard maintenance cycle, and issues SIGALRM if no
6947 progress has been made in the timeout period. This reduces the static
6948 request best-case syscall count to 22 from 29. This scheme is only
6949 used by systems with memory-based scoreboards. [Dean Gaudet]
6951 *) The proxy now properly handles CONNECT requests which are sent
6952 to proxy servers when using ProxyRemote. [Marc Slemko] PR#1024
6954 *) A script called apachectl has been added to the support
6955 directory. This script allows you to do things such as
6956 "apachectl start" and "apachectl restart" from the command
6959 *) Modules and core routines are now put into libraries, which
6960 simplifies the link line tremendously (among other advantages).
6963 *) Some of the MD5 names defined in Apache have been renamed to have
6964 an `ap_' prefix to avoid conflicts with routines supplied by
6965 external libraries. [Ken Coar]
6967 *) Removal of mod_auth_msql.c from the distribution. There are many
6968 other options for databases today. Rather than offer one option,
6969 offer none at this time. mod_auth_msql and other SQL database
6970 authentication modules can be found at the Apache Module Registry.
6971 http://modules.apache.org/ It would be nice to offer a generic
6972 mod_auth_sql option in the near future.
6974 *) PORT: BeOS support added [Alexei Kosut]
6976 *) Configure no longer accepts the -make option, since it creates
6977 Makefile on the fly based on Makefile.tmpl and Configuration.
6979 *) Apache now gracefully shuts down when it receives a SIGTERM, instead
6980 of forcibly killing off all its processes and exiting without
6981 cleaning up. [Alexei Kosut]
6983 *) API: A new field in the request_rec, r->mtime, has been added to
6984 avoid gratuitous parsing of date strings. It is intended to hold
6985 the last-modified date of the resource (if applicable). An
6986 update_mtime() routine has also been added to advance it if
6987 appropriate. [Roy Fielding, Ken Coar]
6989 *) SECURITY: If a htaccess file can not be read due to bad permissions,
6990 deny access to the directory with a HTTP_FORBIDDEN. The previous
6991 behavior was to ignore the htaccess file if it could not be read.
6992 This change may make some setups with unreadable htaccess files
6993 stop working. [Marc Slemko] PR#817
6995 *) Add aplog_error() providing a mechanism to define levels of
6996 verbosity to the server error logging. This addition also provides
6997 the ability to log errors using syslogd. Error logging is configurable
6998 on a per-server basis using the LogLevel directive. Conversion
6999 of log_*() in progress. [Randy Terbush]
7001 *) Further enhance aplog_error() to not log filename, line number, and
7002 errno information when it isn't applicable. [Ken Coar, Dean Gaudet]
7004 *) WIN32: Canonicalise filenames under Win32. Short filenames are
7005 converted to long ones. Backslashes are converted to forward
7006 slashes. Case is converted to lower. Parts of URLs that do not
7007 correspond to files are left completely alone. [Ben Laurie]
7009 *) PORT: 2 new OSs added to the list of ports:
7010 Encore's UMAX V: Arieh Markel <amarkel@encore.com>
7011 Acorn RISCiX: Stephen Borrill <sborrill@xemplar.co.uk>
7013 *) Add the server version (SERVER_VERSION macro) to the "server
7014 configured and running" entry in the error_log. Also build an
7015 object file at link-time that contains the current time
7016 (SERVER_BUILT global const char[]), and include that in the
7019 *) Set r->headers_out when sending responses from the proxy.
7020 This fixes things such as the logging of headers sent from
7021 the proxy. [Marc Slemko] PR#659
7023 *) support/httpd_monitor is no longer distributed because the
7024 scoreboard should not be file based if at all possible. Use
7025 mod_status to see current server snapshot.
7027 *) (set_file_slot): New function, allowing auth directives to be
7028 independent of the server root, so the server documents can be
7029 moved to a different directory or machine more easily.
7030 [David J. MacKenzie]
7032 *) If no TransferLog is given explicitly, decline
7033 to log. This supports coexistence with other logging modules,
7034 such as the custom one that UUNET uses. [David J. MacKenzie]
7036 *) Check for titles in server-parsed HTML files.
7037 Ignore leading newlines and returns in titles. The old behavior
7038 of replacing a newline after <title> with a space causes the
7039 title to be misaligned in the listing. [David J. MacKenzie]
7041 *) Change mod_cern_meta to be configurable on a per-directory basis.
7042 [David J. MacKenzie]
7044 *) Add 'Include' directive to allow inclusion of configuration
7045 files within configuration files. [Randy Terbush]
7047 *) Proxy errors on connect() are logged to the error_log (nothing
7048 new); now they include the IP address and port that failed
7049 (*that's* new). [Ken Coar, Marc Slemko] PR#352
7051 *) Various architectures now define USE_MMAP_FILES which causes
7052 the server to use mmap() for static files. There are two
7053 compile-time tunables MMAP_THRESHOLD (minimum number of bytes
7054 required to use mmap(), default is 0), and MMAP_SEGMENT_SIZE (maximum
7055 number of bytes written in one cycle from a single mmap()d object,
7056 default 32768). [Dean Gaudet]
7058 *) API: Added post_read_request API phase which is run right after reading
7059 the request from a client, or right after an internal redirect. It is
7060 useful for modules setting environment variables that depend only on
7061 the headers/contents of the request. It does not run during subrequests
7062 because subrequests inherit pretty much everything from the main
7063 request. [Dean Gaudet]
7065 *) Added mod_unique_id which is used to generate a unique identifier for
7066 each hit, available in the environment variable UNIQUE_ID.
7069 *) init_modules is now called after the error logs have been opened. This
7070 allows modules to emit information messages into the error logs.
7073 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7074 information for case where proxy module is not available. [Marc Slemko]
7076 *) PORT: Apache has need for mutexes to serialize its children around
7077 accept. In prior versions either fcntl file locking or flock file
7078 locking were used. The method is chosen by the definition of
7079 USE_xxx_SERIALIZED_ACCEPT in conf.h. xxx is FCNTL for fcntl(),
7080 and FLOCK for flock(). New options have been added:
7081 - SYSVSEM to use System V style semaphores
7082 - PTHREAD to use POSIX threads (appears to work on Solaris only)
7083 - USLOCK to use IRIX uslock
7084 Based on timing various techniques, the following changes were made
7086 - Linux 2.x uses flock instead of fcntl
7087 - Solaris 2.x uses pthreads
7088 - IRIX uses SysV semaphores -- however multiprocessor IRIX boxes
7089 work far faster if you -DUSE_USLOCK_SERIALIZED_ACCEPT
7090 [Dean Gaudet, Pierre-Yves Kerembellec <Pierre-Yves.Kerembellec@vtcom.fr>,
7091 Martijn Koster <m.koster@pobox.com>]
7093 *) PORT: The semantics of accept/select make it very desirable to use
7094 mutexes to serialize accept when multiple Listens are in use. But
7095 in the case where only a single socket is open it is sometimes
7096 redundant to serialize accept(). Not all unixes do a good job with
7097 potentially dozens of children blocked on accept() on the same
7098 socket. It's now possible to define SINGLE_LISTEN_UNSERIALIZED_ACCEPT and
7099 the server will avoid serialization when listening on only one socket,
7100 and use serialization when listening on multiple sockets.
7101 [Dean Gaudet] PR#467
7103 *) Configure changes: TestLib replaced by TestCompile, which has
7104 some additional capability (such as doing a sanity check of
7105 the compiler and flags selected); the version of Solaris is now
7106 available via the #define value of SOLARIS2; IRIX n32bit libs
7107 now supported and selectable by new Configuration Rule: IRIXN32;
7108 We no longer default to -O2 optimization. [Jim Jagielski]
7110 *) Updated Configure: Configuration now uses AddModule to specify
7111 module source or binary file location, relative to src directory.
7112 Modules can be dropped into modules/extra, or in their own
7113 directory, and modules can come with a Makefile or Configure can
7114 create one. Modules can add compiler or library information to
7115 generated Makefiles. [Paul Sutton]
7117 *) Source core re-organisation: distributed modules are now in
7118 modules/standard. All other source code is in main. OS-specific
7119 code is in os/{unix,emx,win32} directories. [Paul Sutton]
7121 *) mod_browser has been removed, since it's replaced by mod_setenvif.
7124 *) Fix another long-standing bug in sub_req_lookup_file where it would
7125 happily skip past access checks on subdirectories looked up with
7126 relative paths. (It's used by mod_dir, mod_negotiation,
7127 and mod_include.) [Dean Gaudet]
7129 *) directory_walk optimization to reduce an O(N*M) loop to O(N+M) where
7130 N is the number of <Directory> sections, and M is the number of
7131 components in the filename of an object.
7133 To achieve this optimization the following config changes were made:
7134 - Wildcards (* and ?, not the regex forms) in <Directory>s,
7135 <Files>s, and <Location>s now treat a slash as a special
7136 character. For example "/home/*/public_html" previously would
7137 match "/home/a/andrew/public_html", now it only matches things
7138 like "/home/bob/public_html". This mimics /bin/sh behaviour.
7139 - It's possible now to use [] wildcarding in <Directory>, <Files>
7141 - Regex <Directory>s are applied after all non-regex <Directory>s.
7145 *) Fix a bug introduced in 1.3a1 directory_walk regarding .htaccess files
7146 and corrupted paths. [Dean Gaudet]
7148 *) Enhanced and cleaned up the URL rewriting engine of mod_rewrite:
7149 First the grouped parts of RewriteRule pattern matches (parenthesis!) can
7150 be accessed now via backreferences $1..$9 in RewriteConds test-against
7151 strings in addition to RewriteRules subst string. Second the grouped
7152 parts of RewriteCond pattern matches (parenthesis!) can be accessed now
7153 via backreferences %1..%9 both in following RewriteCond test-against
7154 strings and RewriteRules subst string. This provides maximum flexibility
7155 through the use of backreferences.
7156 Additionally the rewriting engine was cleaned up by putting common
7157 code to the new expand_backrefs_inbuffer() function.
7158 [Ralf S. Engelschall]
7160 *) When merging the main server's <Directory> and <Location> sections into
7161 a vhost, put the main server's first and the vhost's second. Otherwise
7162 the vhost can't override the main server. [Dean Gaudet] PR#717
7164 *) The <Directory> code would merge and re-merge the same section after
7165 a match was found, possibly causing problems with some modules.
7168 *) ip-based vhosts are stored and queried using a hashing function, which
7169 has been shown to improve performance on servers with many ip-vhosts.
7170 Some other changes had to be made to accommodate this:
7171 - the * address for vhosts now behaves like _default_
7172 - the matching process now is:
7173 - match an ip-vhost directly via hash (possibly matches main
7175 - if that fails, just pretend it matched the main server
7176 - if so far only the main server has been matched, perform
7177 name-based lookups (ServerName, ServerAlias, ServerPath)
7178 *only on name-based vhosts*
7179 - if they fail, look for _default_ vhosts
7180 [Dean Gaudet, Dave Hankins <dhankins@sugarat.net>]
7182 *) dbmmanage overhaul:
7183 - merge dbmmanage and dbmmanage.new functionality, remove dbmmanage.new
7184 - tie() to AnyDBM_File which will use one of DB_File, NDBM_File or
7185 GDBM_File (-ldb, -lndbm, -lgdbm) (trying each in that order)
7186 - provide better seed for rand
7187 - prompt for password as per getpass(3) (turn off echo, read from
7189 - use "newstyle" crypt based on $Config{osname} ($^O)
7190 - will not add a user if already in database, use new `update' command
7192 - added `check' command to check a users' password
7193 - added `import' command to convert existing password text-files or
7194 dbm files exported with `view'
7195 - more descriptive usage, general cleanup, 'use strict' clean, etc.
7198 *) Added psocket() which is a pool form of socket(), various places within
7199 the proxy weren't properly blocking alarms while registering the cleanup
7200 for its sockets. bclose() now uses pclose() and pclosesocket(). There
7201 was a bug where the client socket was being close()d twice due a still
7202 registered cleanup. [Dean Gaudet]
7204 *) A few cleanups were made to reduce time(), getpid(), and signal() calls.
7207 *) PORT: AIX >= 4.2 requires -lm due to libc changes.
7208 [Jason Venner <jason@idiom.com>] PR#667
7210 *) Enable ``=""'' for RewriteCond directives to match against
7211 the empty string. This is the preferred way instead of ``^$''.
7212 [Ralf S. Engelschall]
7214 *) Fixed an infinite loop in mod_imap for references above the server root
7215 [Dean Gaudet] PR#748
7217 *) mod_proxy now has a ReceiveBufferSize directive, similar to
7218 SendBufferSize, so that the TCP window can be set appropriately
7219 for LFNs. [Phillip A. Prindeville]
7221 *) mod_browser has been replaced by the more general mod_setenvif
7222 (courtesy of Paul Sutton). BrowserMatch* directives are still
7223 available, but are now joined by SetEnvIf*, UnSetEnvIf*, and
7224 UnSetEnvIfZero directives. [Ken Coar]
7226 *) "HostnameLookups double" forces double-reverse DNS to succeed in
7227 order for remote_host to be set (for logging, or for the env var
7228 REMOTE_HOST). The old define MAXIMUM_DNS has been deprecated.
7231 *) mod_access overhaul:
7232 - Now understands network/netmask syntax (i.e. 10.1.0.0/255.255.0.0)
7233 and cidr syntax (i.e. 10.1.0.0/16). PR#762
7234 - Critical path was sped up by pre-computing a few things at config time.
7235 - The undocumented syntax "allow user-agents" was removed,
7236 the replacement is "allow from env=foobar" combined with mod_browser.
7237 - When used with hostnames it now forces a double-reverse lookup
7238 no matter what the directory settings are. This double-reverse
7239 doesn't affect any of the other routines that use the remote
7240 hostname. In particular it's still passed to CGIs and the log
7241 without the double-reverse check. Related PR#860.
7244 *) When a large bwrite() occurs (larger than the internal buffer size),
7245 while there is already something in the buffer, apache will combine
7246 the large write and the buffer into a single writev(). (This is
7247 in anticipation of using mmap() for reading files.)
7250 *) In obscure cases where a partial socket write occurred while chunking,
7251 Apache would omit the chunk header/footer on the next block. Cleaned
7252 up other bugs/inconsistencies in error conditions in buff.c. Fixed
7253 a bug where a long pause in DNS lookups could cause the last packet
7254 of a response to be unduly delayed. [Roy Fielding, Dean Gaudet]
7256 *) API: Added child_exit function to module structure. This is called
7257 once per "heavy-weight process" just before a server child exit()'s
7258 e.g. when max_requests_per_child is reached, etc.
7259 [Doug MacEachern, Dean Gaudet]
7261 *) mod_include cleanup showed that handle_else was being used to handle
7262 endif. It didn't cause problems, but it was cleaned up too.
7265 *) mod_cern_meta would attempt to find meta files for the directory itself
7266 in some cases, but not in others. It now avoids it in all cases.
7269 *) mod_mime_magic would core dump if there was a decompression error.
7270 [Martin Kraemer <Martin.Kraemer@mch.sni.de>] PR#904
7272 *) PORT: some variants of DGUX require -lsocket -lnsl
7273 [Alexander L Jones <alex@systems-options.co.uk>] PR#732
7275 *) mod_autoindex now allows sorting of FancyIndexed directory listings
7276 by the various fields (name, size, et cetera), either in ascending
7277 or descending order. Just click on the column header. [Ken Coar]
7279 *) PORT: Various tweaks to eliminate pointer-int casting warnings on 64-bit
7280 CPUs like the Alpha. Apache still stores ints in pointers, but that's
7281 the relatively safe direction. [Dean Gaudet] PR#344
7283 *) PORT: QNX mmap() support for faster/more reliable scoreboard handling.
7284 [Igor N Kovalenko <infoh@mail.wplus.net>] PR#683
7286 *) child_main avoids an unneeded call to select() when there is only one
7287 listening socket. [Dean Gaudet]
7289 *) In the event that the server is starved for idle servers it will
7290 spawn 1, then 2, then 4, ..., then 32 servers each second,
7291 doubling each second. It'll also give a warning in the errorlog
7292 since the most common reason for this is a poor StartServers
7293 setting. The define MAX_SPAWN_RATE can be used to raise/lower
7294 the maximum. [Dean Gaudet]
7296 *) Apache now provides an effectively unbuffered connection for
7297 CGI scripts. This means that data will be sent to the client
7298 as soon as the CGI pauses or stops output; previously, Apache would
7299 buffer the output up to a fixed buffer size before sending, which
7300 could result in the user viewing an empty page until the CGI finished
7301 or output a complete buffer. It is no longer necessary to use an
7302 "nph-" CGI to get unbuffered output. Given that most CGIs are written
7303 in a language that by default does buffering (e.g. perl) this
7304 shouldn't have a detrimental effect on performance.
7306 "nph-" CGIs, which formerly provided a direct socket to the client
7307 without any server post-processing, were not fully compatible with
7308 HTTP/1.1 or SSL support. As such they would have had to implement
7309 the transport details, such as encryption or chunking, in order
7310 to work properly in certain situations. Now, the only difference
7311 between nph and non-nph scripts is "non-parsed headers".
7312 [Dean Gaudet, Sameer Parekh, Roy Fielding]
7314 *) If a BUFF is switched from buffered to unbuffered reading the first
7315 bread() will return whatever remained in the buffer prior to the
7316 switch. [Dean Gaudet]
7318 Changes with Apache 1.3a1
7320 *) Added another Configure helper script: TestLib. It determines
7321 if a specified library exists. [Jim Jagielski]
7323 *) PORT: Allow for use of n32bit libraries under IRIX 6.x
7324 [derived from patch from Jeff Hayes <jhayes@aw.sgi.com>]
7327 *) PORT: Some architectures use size_t for various lengths in network
7328 functions such as accept(), and getsockname(). The definition
7329 NET_SIZE_T is used to control this. [Dean Gaudet]
7331 *) PORT: Linux: Attempt to detect glibc based systems and include crypt.h
7332 and -lcrypt. Test for various db libraries (dbm, ndbm, db) when
7333 mod_auth_dbm or mod_auth_db are included. [Dean Gaudet]
7335 *) PORT: QNX doesn't have initgroups() which support/suexec.c uses.
7336 [Igor N Kovalenko <infoh@mail.wplus.net>]
7338 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7339 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7340 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7341 [Dean Gaudet] related PR#875
7343 *) API: Correct child_init() slot declaration from int to void, to
7344 match the init() declaration. Update mod_example to use the new

7361 *) AddModuleInfo directive for mod_info which allows you to annotate
7362 the output of mod_info. ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7364 *) Added NoProxy directive to avoid using ProxyRemote for selected
7365 addresses. Added ProxyDomain directive to cause unqualified
7366 names to be qualified by redirection.
7367 [Martin Kraemer <Martin.Kraemer@mch.sni.de>]
7369 *) Support Proxy Authentication, and don't pass the Proxy-Authorize
7370 header to the remote host in the proxy. [Sameer Parekh and
7373 *) Upgraded mod_rewrite from 3.0.6+ to latest officially available version
7374 3.0.9. This upgrade includes: fixed deadlooping on rewriting to same
7375 URLs, fixed rewritelog(), fixed forced response code handling on
7376 redirects from within .htaccess files, disabled pipe locking under
7377 braindead SunOS 4.1.x, allow env variables to be set even on rules with
7378 no substitution, bugfixed situations where HostnameLookups is off, made
7379 mod_rewrite more thread-safe for NT port and fixed problem when creating
7380 an empty query string via "xxx?".
7381 This update also removes the copyright of Ralf S. Engelschall,
7382 i.e. now mod_rewrite no longer has a shared copyright. Instead is is
7383 exclusively copyrighted by the Apache Group now. This happened because
7384 the author now has gifted mod_rewrite exclusively to the Apache Group and
7385 no longer maintains an external version.
7386 [Ralf S. Engelschall]
7388 *) API: Added child_init function to module structure. This is called
7389 once per "heavy-weight process" before any requests are handled.
7390 See http_config.h for more details. [Dean Gaudet]
7392 *) Anonymous_LogEmail was logging on each subrequest.

7395 *) API: Added is_initial_req() which tests if the request being
7396 processed is the initial request, or a subrequest.

7413 compiled with the multithreaded DLL version of the runtime library.
7414 [Alexei Kosut and Ben Laurie]
7416 *) Automatic indexing removed from mod_dir and placed into mod_autoindex.
7417 This allows the admin to completely remove automatic indexing
7418 from the server, while still supporting the basic functions of
7419 trailing-slash redirects and DirectoryIndex files. Note that if
7420 you're carrying over an old Configuration file and you use directory
7421 indexing then you'll want to add:
7423 Module autoindex_module mod_autoindex.o
7425 before mod_dir in your Configuration. [Dean Gaudet]
7427 *) popendir/pclosedir created to properly protect directory scanning.
7428 [Dean Gaudet] PR#525
7430 *) AliasMatch, ScriptAliasMatch and RedirectMatch directives added,
7431 giving regex support to mod_alias. <DirectoryMatch>, <LocationMatch>
7432 and <FilesMatch> sections added to succeed <DirectoryMatch ~>, etc...
7435 *) The AccessFileName directive can now take more than one filename.
7436 ["Lou D. Langholtz" <ldl@usi.utah.edu>]
7438 *) The new mod_mime_magic can be used to "magically" determine the type
7439 of a file if the extension is unknown. Based on the unix file(1)
7440 command. [Ian Kluft <ikluft@cisco.com>]
7442 *) We now determine and display the time spent processing a
7443 request if desired. [Jim Jagielski]
7445 *) mod_status: PID field of "dead" child slots no longer displays
7446 main httpd process's PID. [Jim Jagielski]
7448 *) Makefile.nt added - to build all the bits from the command line:
7449 nmake -f Makefile.nt
7450 Doesn't yet work properly. [Ben Laurie]
7452 *) Default text of 404 error is now "Not Found" rather than the
7453 potentially misleading "File Not Found". [Ken Coar]
7455 *) CONFIG: "HostnameLookups" now defaults to off because it is far better
7456 for the net if we require people that actually need this data to
7457 enable it. [Linus Torvalds]
7459 *) directory_walk() is an expensive function, keep a little more state to
7460 avoid needless string counting. Add two new functions make_dirstr_parent
7461 and make_dirstr_prefix which replace all existing uses of make_dirstr.
7462 The new functions are a little less general than make_dirstr, but
7463 work more efficiently (less memory, less string counting).
7466 *) EXTRA_LFLAGS was changed to EXTRA_LDFLAGS (and LFLAGS was changed
7467 to LDFLAGS) to avoid complications with lex rules in make files.
7468 [Dean Gaudet] PR#372
7470 *) run_method optimized to avoid needless scanning over NULLs in the
7471 module list. [Dean Gaudet]
7473 *) Revamp of (unix) scoreboard management code such that it avoids
7474 unnecessary traversals of the scoreboard on each hit. This is
7475 particularly important for high volume sites with a large
7476 HARD_SERVER_LIMIT. Some of the previous operations were O(n^2),
7477 and are now O(n). See also SCOREBOARD_MAINTENANCE_INTERVAL in
7478 httpd.h. [Dean Gaudet]
7480 *) In configurations using multiple Listen statements it was possible for
7481 busy sockets to starve other sockets of service. [Dean Gaudet]
7483 *) Added hook so standalone_main can be replaced at compile time
7484 (define STANDALONE_MAIN)
7487 *) Lowest-level read/write functions in buff.c will be replaced with
7488 the SFIO library calls sfread/sfwrite if B_SFIO is defined at
7489 compile time. The default sfio discipline will behave as apache
7490 would without sfio compiled in.
7493 *) Enhance UserDir directive (mod_userdir) to accept a list of
7494 usernames for the 'disable' keyword, and add 'enable user...' to
7495 selectively *en*able userdirs if they're globally disabled.
7498 *) If NETSCAPE_DBM_COMPAT is defined in EXTRA_CFLAGS then Apache
7499 will work with Netscape dbm files. (dbmmanage will probably not
7500 work however.) [Alexander Spohr <aspohr@netmatic.com>] PR#444
7502 *) Add a ListenBacklog directive to control the backlog parameter
7503 passed to listen(). Also change the default to 511 from 512.
7506 *) API: A new handler response DONE which informs apache that the
7507 request has been handled and it can finish off quickly, similar to
7508 how it handles errors. [Rob Hartill]
7510 *) Turn off chunked encoding after sending terminating chunk/footer
7511 so that we can't do it twice by accident. [Roy Fielding]
7513 *) mod_expire also issues Cache-Control: max-age headers.
7516 *) API: Added kill_only_once option for free_proc_chain so that it won't
7517 aggressively try to kill off specific children. For fastcgi.
7518 [Stanley Gambarin <gambarin@OpenMarket.com>]
7520 *) mod_auth deals with extra ':' delimited fields. [Marc Slemko]
7522 *) Added IconHeight and IconWidth to mod_dir's IndexOptions directive.
7523 When used together, these cause mod_dir to emit HEIGHT and WIDTH
7524 attributes in the FancyIndexing IMG tags. [Ken Coar]
7526 *) PORT: Sequent and SONY NEWS-OS support added. [Jim Jagielski]
7528 *) PORT: Added Windows NT support
7529 [Ben Laurie and Ambarish Malpani <ambarish@valicert.com>]
7531 Changes with Apache 1.2.6
7533 *) mod_include when using XBitHack Full would send ETags in addition to
7534 sending Last-Modifieds. This is incorrect HTTP/1.1 behaviour.
7535 [Dean Gaudet] PR#1133
7537 *) SECURITY: When a client connects to a particular port/addr, and
7538 gives a Host: header ensure that the virtual host requested can
7539 actually be reached via that port/addr. [Ed Korthof <ed@organic.com>]
7541 *) Support virtual hosts with wildcard port and/or multiple ports
7542 properly. [Ed Korthof <ed@organic.com>]
7544 *) Fixed some case-sensitivity issues according to RFC2068.
7547 *) Set r->allowed properly in mod_asis.c, mod_dir.c, mod_info.c,
7548 and mod_include.c. [Dean Gaudet]
7550 *) Variable 'cwd' was being used pointlessly before being set.
7553 *) SIGURG doesn't exist on all platforms.
7554 [Mark Andrew Heinrich <heinrich@tinderbox.Stanford.EDU>]
7556 *) When an error occurs during a POST, or other operation with a
7557 request body, the body has to be read from the net before allowing
7558 a keepalive session to continue. [Roy Fielding] PR#1399
7560 *) When an error occurs in fcntl() locking suggest the user look up
7561 the docs for LockFile. [Dean Gaudet]
7563 *) table_set() and table_unset() did not deal correctly with
7564 multiple occurrences of the same key. [Stephen Scheck
7565 <sscheck@infonex.net>, Ben Laurie] PR#1604
7567 *) send_fd_length() did not calculate total_bytes_sent properly in error
7568 cases. [Ben Reser <breser@regnow.com>] PR#1366
7570 *) r->connection->user was allocated in the wrong pool causing corruption
7571 in some cases when used with mod_cern_meta. [Dean Gaudet] PR#1500
7573 *) mod_proxy was sending HTTP/1.1 responses to ftp requests by mistake.
7574 Also removed the auto-generated link to www.apache.org that was the
7575 source of so many misdirected bug reports. [Roy Fielding, Marc Slemko]
7577 *) Multiple "close" tokens may have been set in the "Connection"
7578 header, not an error, but a waste.
7579 [Ronald.Tschalaer@psi.ch] PR#1683
7581 *) "basic" and "digest" auth tokens should be tested case-insensitive.
7582 [Ronald.Tschalaer@psi.ch] PR#1599, PR#1666
7584 *) It appears the "257th byte" bug (see
7585 htdocs/manual/misc/known_client_problems.html#257th-byte) can happen
7586 at the 256th byte as well. Fixed. [Dean Gaudet]
7588 *) mod_rewrite would not handle %3f properly in some situations.
7591 *) Apache could generate improperly chunked HTTP/1.1 responses when
7592 the bputc() or rputc() functions were used by modules (such as
7593 mod_include). [Dean Gaudet]
7595 *) #ifdef wrap a few #defines in httpd.h to make life easier on
7596 some ports. [Ralf Engelschall]
7598 *) Fix MPE compilation error in mod_usertrack.c. [Mark Bixby]
7600 *) Quote CC='$(CC)' to improve recurse make calls. [Martin Kraemer]
7602 *) Avoid B_ERROR redeclaration on sysvr4 systems. [Martin Kraemer]
7604 Changes with Apache 1.2.5
7606 *) SECURITY: Fix a possible buffer overflow in logresolve. This is
7607 only an issue on systems without a MAXDNAME define or where
7608 the resolver returns domain names longer than MAXDNAME. [Marc Slemko]
7610 *) Fix an improper length in an ap_snprintf call in proxy_date_canon().
7613 *) Fix core dump in the ftp proxy when reading incorrectly formatted
7614 directory listings. [Marc Slemko]
7616 *) SECURITY: Fix possible minor buffer overflow in the proxy cache.
7619 *) SECURITY: Eliminate possible buffer overflow in cfg_getline, which
7620 is used to read various types of files such as htaccess and
7621 htpasswd files. [Marc Slemko]
7623 *) SECURITY: Ensure that the buffer returned by ht_time is always
7624 properly null terminated. [Marc Slemko]
7626 *) SECURITY: General mod_include cleanup, including fixing several
7627 possible buffer overflows and a possible infinite loop. This cleanup
7628 was done against 1.3 code and then backported to 1.2, the result
7629 is a large difference (due to indentation cleanup in 1.3 code).
7630 Users interested in seeing a smaller set of relevant differences
7631 should consider comparing against src/modules/standard/mod_include.c
7632 from the 1.3b3 release. Non-indentation changes to mod_include
7633 between 1.2 and 1.3 were minimal. [Dean Gaudet, Marc Slemko]
7635 *) SECURITY: Numerous changes to mod_imap in a general cleanup
7636 including fixing a possible buffer overflow. This cleanup also
7637 was done with 1.3 code as a basis, see the the previous note
7638 about mod_include. [Dean Gaudet]
7640 *) SECURITY: If a htaccess file can not be read due to bad
7641 permissions, deny access to the directory with a HTTP_FORBIDDEN.
7642 The previous behavior was to ignore the htaccess file if it could not
7643 be read. This change may make some setups with unreadable
7644 htaccess files stop working. PR#817 [Marc Slemko]
7646 *) SECURITY: no2slash() was O(n^2) in the length of the input.
7647 Make it O(n). This inefficiency could be used to mount a denial
7648 of service attack against the Apache server. Thanks to
7649 Michal Zalewski <lcamtuf@boss.staszic.waw.pl> for reporting
7652 *) mod_include used uninitialized data for some uses of && and ||.
7653 [Brian Slesinsky <bslesins@wired.com>] PR#1139
7655 *) mod_imap should decline all non-GET methods.
7656 [Jay Bloodworth <jay@pathways.sde.state.sc.us>]
7658 *) suexec.c wouldn't build without -DLOG_EXEC. [Jason A. Dour]
7660 *) mod_userdir was modifying r->finfo in cases where it wasn't setting
7661 r->filename. Since those two are meant to be in sync with each other
7662 this is a bug. ["Paul B. Henson" <henson@intranet.csupomona.edu>]
7664 *) mod_include did not properly handle all possible redirects from sub-
7665 requests. [Ken Coar]
7667 *) Inetd mode (which is buggy) uses timeouts without having setup the
7668 jmpbuffer. [Dean Gaudet] PR#1064
7670 *) Work around problem under Linux where a child will start looping
7671 reporting a select error over and over.
7672 [Rick Franchuk <rickf@transpect.net>] PR#1107
7674 Changes with Apache 1.2.4
7676 *) The ProxyRemote change in 1.2.3 introduced a bug resulting in the proxy
7677 always making requests with the full-URI instead of just the URI path.
7678 [Marc Slemko, Roy Fielding]
7680 *) Add -lm for AIX versions >= 4.2 to allow Apache to link properly
7681 on this platform. [Marc Slemko]
7683 Changes with Apache 1.2.3
7685 *) The request to a remote proxy was mangled if it was generated as the
7686 result of a ProxyPass directive. URL schemes other than http:// were not
7687 supported when ProxyRemote was used. PR#260, PR#656, PR#699, PR#713,
7688 PR#812 [Lars Eilebrecht]
7690 *) Fixed proxy-pass-through feature of mod_rewrite; Added error logging
7691 information for case where proxy module is not available. [Marc Slemko]
7693 *) Force proxy to always respond as HTTP/1.0, which it was failing to
7694 do for errors and cached responses. [Roy Fielding]
7696 *) PORT: Improved support for ConvexOS 11. [Jeff Venters]
7698 Changes with Apache 1.2.2 [not released]
7700 *) Fixed another long-standing bug in sub_req_lookup_file where it would
7701 happily skip past access checks on subdirectories looked up with relative
7702 paths. (It's used by mod_dir, mod_negotiation, and mod_include.)
7705 *) Add lockfile name to error message printed out when
7706 USE_FLOCK_SERIALIZED_ACCEPT is defined.
7709 *) Enhanced the chunking and error handling inside the buffer functions.
7710 [Dean Gaudet, Roy Fielding]
7712 *) When merging the main server's <Directory> and <Location> sections into
7713 a vhost, put the main server's first and the vhost's second. Otherwise
7714 the vhost can't override the main server. [Dean Gaudet] PR#717
7716 *) The <Directory> code would merge and re-merge the same section after
7717 a match was found, possibly causing problems with some modules.
7720 *) Fixed an infinite loop in mod_imap for references above the server root.
7721 [Dean Gaudet] PR#748
7723 *) mod_include cleanup showed that handle_else was being used to handle
7724 endif. It didn't cause problems, but it was cleaned up too.
7727 *) Last official synchronization of mod_rewrite with author version (because
7728 mod_rewrite is now directly developed by the author at the Apache Group):
7729 o added diff between mod_rewrite 3.0.6+ and 3.0.9
7730 minus WIN32/NT stuff, but plus copyright removement.
7732 - workaround for detecting infinite rewriting loops
7733 - fixed setting of env vars when "-" is used as subst string
7734 - fixed forced response code on redirects (PR#777)
7735 - fixed cases where r->args is ""
7736 - kludge to disable locking on pipes under braindead SunOS
7737 - fix for rewritelog in cases where remote hostname is unknown
7738 - fixed totally damaged request_rec walk-back loop
7739 o remove static from local data and add static to global ones.
7740 o replaced ugly proxy finding stuff by simple
7741 find_linked_module("mod_proxy") call.
7742 o added missing negation char on rewritelog()
7743 o fixed a few comment typos
7744 [Ralf S. Engelschall]
7746 *) Anonymous_LogEmail was logging on each subrequest.
7747 [Dean Gaudet] PR#421, PR#868
7749 *) "force-response-1.0" now only applies to requests which are HTTP/1.0 to
7750 begin with. "nokeepalive" now works for HTTP/1.1 clients. Added
7751 "downgrade-1.0" which causes Apache to pretend it received a 1.0.
7752 Additionally mod_browser now triggers during translate_name to workaround
7753 a deficiency in the header_parse phase.
7754 [Dean Gaudet] PR#875

7760 *) Properly treat <files> container like other containers in mod_info.
7761 [Marc Slemko] PR#848
7763 *) The proxy didn't treat the "Host:" keyword of the host header as case-
7764 insensitive. The proxy would corrupt the first line of a response from
7765 an HTTP/0.9 server. [Kenichi Hori <ken@d2.bs1.fc.nec.co.jp>] PR#813,814
7767 *) mod_include would log some bogus values occasionally.
7768 [Skip Montanaro <skip@calendar.com>, Marc Slemko] PR#797
7770 *) PORT: The slack fd changes in 1.2.1 introduced a problem with SIGHUP
7771 under Solaris 2.x (up through 2.5.1). It has been fixed.
7772 [Dean Gaudet] PR#832
7774 *) API: In HTTP/1.1, whether or not a request message contains a body
7775 is independent of the request method and based solely on the presence
7776 of a Content-Length or Transfer-Encoding. Therefore, our default
7777 handlers need to be prepared to read a body even if they don't know
7778 what to do with it; otherwise, the body would be mistaken for the
7779 next request on a persistent connection. discard_request_body()
7780 has been added to take care of that. [Roy Fielding] PR#378
7782 *) API: Symbol APACHE_RELEASE provides a numeric form of the Apache
7783 release version number, such that it always increases along the
7784 same lines as our source code branching. [Roy Fielding]
7786 *) Minor oversight on multiple variants fixed. [Paul Sutton] PR#94
7788 Changes with Apache 1.2.1
7790 *) SECURITY: Don't serve file system objects unless they are plain files,
7791 symlinks, or directories. This prevents local users from using pipes
7792 or named sockets to invoke programs for an extremely crude form of

7796 could contain "../" allowing a local user to "publish" any file on
7797 the system. No slashes are allowed now. [Dean Gaudet]
7799 *) SECURITY: It was possible to violate the symlink Options using mod_dir
7800 (headers, readmes, titles), mod_negotiation (type maps), or
7801 mod_cern_meta (meta files). [Dean Gaudet]
7803 *) SECURITY: Apache will refuse to run as "User root" unless
7804 BIG_SECURITY_HOLE is defined at compile time. [Dean Gaudet]
7806 *) CONFIG: If a symlink pointed to a directory then it would be disallowed
7807 if it contained a .htaccess disallowing symlinks. This is contrary
7808 to the rule that symlink permissions are tested with the symlink
7809 options of the parent directory. [Dean Gaudet] PR#353
7811 *) CONFIG: The LockFile directive can be used to place the serializing
7812 lockfile in any location. It previously defaulted to /usr/tmp/htlock.
7813 [Somehow it took four of us: Randy Terbush, Jim Jagielski, Dean Gaudet,
7816 *) Request processing now retains state of whether or not the request
7817 body has been read, so that internal redirects and subrequests will
7818 not try to read it twice (and block). [Roy Fielding]
7820 *) Add a placeholder in modules/Makefile to avoid errors with certain
7821 makes. [Marc Slemko]
7823 *) QUERY_STRING was unescaped in mod_include, it shouldn't be.

7827 [Marc Slemko] PR#742
7829 *) Attempt to work around problems with third party libraries that do not
7830 handle high numbered descriptors (examples include bind, and
7831 solaris libc). On all systems apache attempts to keep all permanent
7832 descriptors above 15 (called the low slack line). Solaris users
7833 can also benefit from adding -DHIGH_SLACK_LINE=256 to EXTRA_CFLAGS
7834 which keeps all non-FILE * descriptors above 255. On all systems
7835 this should make supporting large numbers of vhosts with many open
7836 log files more feasible. If this causes trouble please report it,
7837 you can disable this workaround by adding -DNO_SLACK to EXTRA_CFLAGS.
7838 [Dean Gaudet] various PRs
7840 *) Related to the last entry, network sockets are now opened before
7841 log files are opened. The only known case where this can cause
7842 problems is under Solaris with many virtualhosts and many Listen
7843 directives. But using -DHIGH_SLACK_LINE=256 described above will
7844 work around this problem. [Dean Gaudet]
7846 *) USE_FLOCK_SERIALIZED_ACCEPT is now default for FreeBSD, A/UX, and
7849 *) Improved unix error response logging. [Marc Slemko]
7851 *) Update mod_rewrite from 3.0.5 to 3.0.6. New ruleflag
7852 QSA=query_string_append. Also fixed a nasty bug in per-dir context:

7899 reading from one buffer and writing to another, at least until it has
7900 a custom timeout handler. [Roy Fielding and Petr Lampa]
7902 *) Fixed problem on IRIX with servers hanging in IdentityCheck,

7941 CC=/OPTIM= format in Configuration. Finally, fix compiler
7942 flags if using HP-UX's cc compiler. [Jim Jagielski]
7944 *) Subrequests and internal redirects now inherit the_request from the
7945 original request-line. [Roy Fielding]

7948 we don't want the error message to include those fields. Likewise,
7949 reset the content_language(s) and content_encoding of the response

7967 *) Properly initialize the flock structures used by the mutex locking
7968 around accept() when USE_FCNTL_SERIALIZED_ACCEPT is defined.
7971 *) The method for determining PATH_INFO has been restored to the pre-1.2b
7972 (and NCSA httpd) definition wherein it was the extra path info beyond
7973 the CGI script filename. The environment variable FILEPATH_INFO has
7974 been removed, and instead we supply the original REQUEST_URI to any
7975 script that wants to be Apache-specific and needs the real URI path.
7976 This solves a problem with existing scripts that use extra path info
7977 in the ScriptAlias directive to pass options to the CGI script.
7980 *) The _default_ change in 1.2b10 will change the behaviour on configs
7981 that use multiple Listen statements for listening on multiple ports.
7982 But that change is necessary to make _default_ consistent with other
7983 forms of <VirtualHost>. It requires such configs to be modified
7984 to use <VirtualHost _default_:*>. The documentation has been
7985 updated. [Dean Gaudet] PR#530
7987 *) If an ErrorDocument CGI script is used to respond to an error
7988 generated by another CGI script which has already read the message
7989 body of the request, the server would block trying to read the
7990 message body again. [Rob Hartill]
7992 *) signal() replacement conflicted with a define on QNX (and potentially
7993 other platforms). Fixed. [Ben Laurie] PR#512
7995 Changes with Apache 1.2b10
7997 *) Allow HTTPD_ROOT, SERVER_CONFIG_FILE, DEFAULT_PATH, and SHELL_PATH
7998 to be configured via -D in Configuration. [Dean Gaudet] PR#449
8000 *) <VirtualHost _default_:portnum> didn't work properly. [Dean Gaudet]
8002 *) Added prototype for mktemp() for SUNOS4 [Marc Slemko]
8004 *) In mod_proxy.c, check return values for proxy_host2addr() when reading
8005 config, in case the hostent struct returned is trash.
8006 [Chuck Murcko] PR #491
8008 *) Fixed the fix in 1.2b9 for parsing URL query info into args for CGI
8009 scripts. [Dean Gaudet, Roy Fielding, Marc Slemko]
8011 Changes with Apache 1.2b9 [never announced]
8013 *) Reset the MODULE_MAGIC_NUMBER to account for the unsigned port
8014 changes and in anticipation of 1.2 final release. [Roy Fielding]
8016 *) Fix problem with scripts not receiving a SIGPIPE when client drops
8017 the connection (e.g., when user presses Stop). Apache will now stop
8018 trying to send a message body immediately after an error from write.
8019 [Roy Fielding and Nathan Kurz] PR#335
8021 *) Rearrange Configuration.tmpl so that mod_rewrite has higher priority
8022 than mod_alias, and mod_alias has higher priority than mod_proxy;
8023 rearranged other modules to enhance understanding of their purpose
8024 and relative order (and maybe even reduce some overhead).
8025 [Roy Fielding and Sameer Parekh]
8027 *) Fix graceful restart. Eliminate many signal-related race
8028 conditions in both forms of restart, and in SIGTERM. See
8029 htdocs/manual/stopping.html for details on stopping and
8030 restarting the parent. [Dean Gaudet]
8032 *) Fix memory leaks in mod_rewrite, mod_browser, mod_include. Tune
8033 memory allocator to avoid a behaviour that required extra blocks to
8034 be allocated. [Dean Gaudet]
8036 *) Allow suexec to access files relative to current directory but not
8037 above. (Excluding leading / or any .. directory.) [Ken Coar]
8040 *) Fix suexec segfault when group doesn't exist. [Gregory Neil Shapiro]
8041 PR#367, 368, 354, 453
8043 *) Fix the above fix: if suexec is enabled, avoid destroying r->url
8044 while obtaining the /~user and save the username in a separate data
8045 area so that it won't be overwritten by the call to getgrgid(), and
8046 fix some misuse of the pool string allocation functions. Also fixes
8047 a general problem with parsing URL query info into args for CGI scripts.
8048 [Roy Fielding] PR#339, 367, 354, 453
8050 *) Fix IRIX warning about bzero undefined. [Marc Slemko]
8052 *) Fix problem with <Directory proxy:...>. [Martin Kraemer] PR#271
8054 *) Corrected spelling of "authoritative". AuthDBAuthoratative became
8055 AuthDBAuthoritative. [Marc Slemko] PR#420
8057 *) MaxClients should be at least 1. [Lars Eilebrecht] PR#375
8059 *) The default handler now logs invalid methods or URIs (i.e. PUT on an
8060 object that can't be PUT, or FOOBAR for some method FOOBAR that
8061 apache doesn't know about at all). Log 404s that occur in mod_include.
8062 [Paul Sutton, John Van Essen]
8064 *) If a soft timeout (or lingerout) occurs while trying to flush a
8065 buffer or write inside buff.c or fread'ing from a CGI's output,
8066 then the timeout would be ignored. [Roy Fielding] PR#373
8068 *) Work around a bug in Netscape Navigator versions 2.x, 3.x and 4.0b2's
8069 parsing of headers. If the terminating empty-line CRLF occurs starting
8070 at the 256th or 257th byte of output, then Navigator will think a normal
8071 image is invalid. We are guessing that this is because their initial
8072 read of a new request uses a 256 byte buffer. We check the bytes written
8073 so far and, if we are about to tickle the bug, we instead insert a
8074 padding header of eminent bogosity. [Roy Fielding and Dean Gaudet] PR#232
8076 *) Fixed SIGSEGV problem when a DirectoryIndex file is also the source
8077 of an external redirection. [Roy Fielding and Paul Sutton]
8079 *) Configure would create a broken Makefile if the configuration file
8080 contained a commented-out Rule. [Roy Fielding]
8082 *) Promote per_dir_config and subprocess_env from the subrequest to the
8083 main request in mod_negotiation. In particular this fixes a bug
8084 where <Files> sections wouldn't properly apply to negotiated content.
8087 *) Fix a potential deadlock in mod_cgi script_err handling.
8088 [Ralf S. Engelschall]
8090 *) rotatelogs zero-pads the logfile names to improve alphabetic sorting.
8093 *) Updated mod_rewrite to 3.0.4: Fixes HTTP redirects from within
8094 .htaccess files because the RewriteBase was not replaced correctly.
8095 Updated mod_rewrite to 3.0.5: Fixes problem with rewriting inside
8096 <Directory> sections missing a trailing /. [Ralf S. Engelschall]
8098 *) Clean up Linux settings in conf.h by detecting 2.x versus 1.x. For
8099 1.x the settings are those of pre-1.2b8. For 2.x we include
8100 USE_SHMGET_SCOREBOARD (scoreboard in shared memory rather than file) and
8101 HAVE_SYS_RESOURCE_H (enable the RLimit commands).
8102 [Dean Gaudet] PR#336, PR#340
8104 *) Redirect did not preserve ?query_strings when present in the client's
8105 request. [Dean Gaudet]
8107 *) Configure was finding non-modules on EXTRA_LIBS. [Frank Cringle] PR#380
8109 *) Use /bin/sh5 on ULTRIX. [P. Alejandro Lopez-Valencia] PR#369
8111 *) Add UnixWare compile/install instructions. [Chuck Murcko]
8113 *) Add mod_example (illustration of API techniques). [Ken Coar]
8115 *) Add macro for memmove to conf.h for SUNOS4. [Marc Slemko]
8117 *) Improve handling of directories when filenames have spaces in them.
8120 *) For hosts with multiple IP addresses, try all additional addresses if
8121 necessary to get a connect. Fail only if hostent address list is
8122 exhausted. [Chuck Murcko]
8124 *) More signed/unsigned port fixes. [Dean Gaudet]
8126 *) HARD_SERVER_LIMIT can be defined in the Configuration file now.
8129 Changes with Apache 1.2b8
8131 *) suexec.c doesn't close the log file, allowing CGIs to continue writing
8132 to it. [Marc Slemko]
8134 *) The addition of <Location> and <File> directives made the
8135 sub_req_lookup_simple() function bogus, so we now handle
8136 the special cases directly. [Dean Gaudet]
8138 *) We now try to log where the server is dumping core when a fatal
8139 signal is received. [Ken Coar]
8141 *) Improved lingering_close by adding a special timeout, removing the
8142 spurious log messages, removing the nonblocking settings (they
8143 are not needed with the better timeout), and adding commentary
8144 about the NO_LINGCLOSE and USE_SO_LINGER issues. NO_LINGCLOSE is
8145 now the default for SunOS4, UnixWare, NeXT, and IRIX. [Roy Fielding]
8147 *) Send error messages about setsockopt failures to the server error
8148 log instead of stderr. [Roy Fielding]
8150 *) Fix loopholes in proxy cache expiry vis a vis alarms. [Brian Moore]
8152 *) Stopgap solution for CGI 3-second delay with server-side includes: if
8153 processing a subrequest, allocate memory from r->main->pool instead
8154 of r->pool so that we can avoid waiting for free_proc_chain to cleanup
8155 in the middle of an SSI request. [Dean Gaudet] PR #122
8157 *) Fixed status of response when POST is received for a nonexistent URL
8158 (was sending 405, now 404) and when any method is sent with a
8159 full-URI that doesn't match the server and the server is not acting
8160 as a proxy (was sending 501, now 403). [Roy Fielding]
8162 *) Host port changed to unsigned short. [Ken Coar] PR #276
8164 *) Fix typo in command definition of AuthAuthoritative. [Ken Coar] PR #246
8166 *) Defined USE_SHMGET_SCOREBOARD for shared memory on Linux. [Dean Gaudet]
8168 *) Report extra info from errno with many errors that cause httpd to exit.
8169 spawn_child, popenf, and pclosef now have valid errno returns in the
8170 event of an error. Correct problems where errno was stomped on
8171 before being reported. [Dean Gaudet]
8173 *) In the proxy, if the cache filesystem was full, garbage_coll() was
8174 never called, and thus the filesystem would remain full indefinitely.
8175 We now also remove incomplete cache files left if the origin server
8176 didn't send a Content-Length header and either the client has aborted
8177 transfer or bwrite() to client has failed. [Petr Lampa]
8179 *) Fixed the handling of module and script-added header fields.
8180 Improved the interface for sending header fields and reduced
8181 the duplication of code between sending okay responses and errors.
8182 We now always send both headers_out and err_headers_out, and
8183 ensure that the server-reserved fields are not being overridden,
8184 while not overriding those that are not reserved. [Roy Fielding]
8186 *) Moved transparent content negotiation fields to err_headers_out
8187 to reflect above changes. [Petr Lampa]
8189 *) Fixed the determination of whether or not we should make the
8190 connection persistent for all of the cases where some other part
8191 of the server has already indicated that we should not. Also
8192 improved the ordering of the test so that chunked encoding will
8193 be set whenever it is desired instead of only when KeepAlive
8194 is enabled. Added persistent connection capability for most error
8195 responses (those that do not indicate a bad input stream) when
8196 accessed by an HTTP/1.1 client. [Roy Fielding]
8198 *) Added missing timeouts for sending header fields, error responses,
8199 and the last chunk of chunked encoding, each of which could have
8200 resulted in a process being stuck in write forever. Using soft_timeout
8201 requires that the sender check for an aborted connection rather than
8202 continuing after an EINTR. Timeouts that used to be initiated before
8203 send_http_header (and never killed) are now initiated only within or
8204 around the routines that actually do the sending, and not allowed to
8205 propagate above the caller. [Roy Fielding]
8207 *) mod_auth_anon required an @ or a . in the email address, not both.
8210 *) per_dir_defaults weren't set correctly until directory_walk for
8211 name-based vhosts. This fixes an obscure bug with the wrong config
8212 info being used for vhosts that share the same ip as the server.
8215 *) Improved generation of modules/Makefile to be more generic for
8216 new module directories. [Ken Coar, Chuck Murcko, Roy Fielding]
8218 *) Generate makefile dependency for Configuration based on the actual
8219 name given when running the Configure process. [Dean Gaudet]
8221 *) Fixed problem with vhost error log not being set prior to
8222 initializing virtual hosts. [Dean Gaudet]
8224 *) Fixed infinite loop when a trailing slash is included after a type map
8225 file URL (extra path info). [Petr Lampa]
8227 *) Fixed server status updating of per-connection counters. [Roy Fielding]
8229 *) Add documentation for DNS issues (reliability and security), and try
8230 to explain the virtual host matching process. [Dean Gaudet]
8232 *) Try to continue gracefully by disabling the vhost if a DNS lookup
8233 fails while parsing the configuration file. [Dean Gaudet]
8235 *) Improved calls to setsockopt. [Roy Fielding]
8237 *) Negotiation changes: Don't output empty content-type in variant list;
8238 Output charset in variant list; Return sooner from handle_multi() if
8239 no variants found; Add handling of '*' wildcard in Accept-Charset.
8240 [Petr Lampa and Paul Sutton]
8242 *) Fixed overlaying of request/sub-request notes and headers in
8243 mod_negotiation. [Dean Gaudet]
8245 *) If two variants' charset quality are equal and one is the default
8246 charset (iso-8859-1), then prefer the variant that was specifically
8247 listed in Accept-Charset instead of the default. [Petr Lampa]
8249 *) Memory allocation problem in push_array() -- it would corrupt memory
8250 when nalloc==0. [Kai Risku <krisku@tf.hut.fi> and Roy Fielding]
8252 *) invoke_handler() doesn't handle mime arguments in content-type
8255 *) Reduced IdentityCheck timeout to 30 seconds, as per RFC 1413 minimum.
8258 *) Fixed problem with ErrorDocument not working for virtual hosts
8259 due to one of the performance changes in 1.2b7. [Dean Gaudet]
8261 *) Log an error message if we get a request header that is too long,
8262 since it may indicate a buffer overflow attack. [Marc Slemko]
8264 *) Made is_url() allow "[-.+a-zA-Z0-9]+:" as a valid scheme and
8265 not reject URLs without a double-slash, as per RFC2068 section 3.2.
8266 [Ken Coar] PR #146, #187
8268 *) Added table entry placeholder for new header_parser callback
8269 in all of the distributed modules. [Ken Coar] PR #191
8271 *) Allow for cgi files without the .EXE extension on them under OS/2.
8272 [Garey Smiley] PR #59
8274 *) Fixed error message when resource is not found and URL contains
8275 path info. [Petr Lampa and Dean Gaudet] PR #40
8277 *) Fixed user and server confusion over what should be a virtual host
8278 and what is the main server, resulting in access to something
8279 other than the name defined in the virtualhost directive (but
8280 with the same IP address) failing. [Dean Gaudet]
8282 *) Updated mod_rewrite to version 3.0.2, which: fixes compile error on
8283 AIX; improves the redirection stuff to enable the users to generally
8284 redirect to http, https, gopher and ftp; added TIME variable for
8285 RewriteCond which expands to YYYYMMDDHHMMSS strings and added the
8286 special patterns >STRING, <STRING and =STRING to RewriteCond, which
8287 can be used in conjunction with %{TIME} or other variables to create
8288 time-dependent rewriting rules. [Ralf S. Engelschall]
8290 *) bpushfd() no longer notes cleanups for the file descriptors it is handed.
8291 Module authors may need to adjust their code for proper cleanup to take
8292 place (that is, call note_cleanups_for_fd()). This change fixes problems
8293 with file descriptors being erroneously closed when the proxy module was
8294 in use. [Ben Laurie]
8296 *) Fix bug in suexec reintroduced by changes in 1.2b7 which allows
8297 initgroups() to hose the group information needed for later
8298 comparisons. [Randy Terbush]
8300 *) Remove unnecessary call to va_end() in create_argv() which
8301 caused a SEGV on some systems.
8303 *) Use proper MAXHOSTNAMELEN symbol for limiting length of server name.
8306 *) Clear memory allocated for listeners. [Randy Terbush]
8308 *) Improved handling of IP address as a virtualhost address and
8309 introduced "_default_" as a synonym for the default vhost config.
8310 [Dean Gaudet] PR #212
8312 Changes with Apache 1.2b7
8314 *) Port to UXP/DS(V20) [Toshiaki Nomura <nom@yk.fujitsu.co.jp>]
8316 *) unset Content-Length if chunked (RFC-2068) [Petr Lampa]
8318 *) mod_negotiation fixes [Petr Lampa] PR#157, PR#158, PR#159
8319 - replace protocol response numbers with symbols
8320 - save variant-list into main request notes
8321 - free allocated memory from subrequests
8322 - merge notes, headers_out and err_headers_out
8324 *) changed status check mask in proxy_http.c from "HTTP/#.# ### *" to
8325 "HTTP/#.# ###*" to be more lenient about what we accept.
8328 *) more proxy FTP bug fixes:
8329 - Changed send_dir() to remove user/passwd from displayed URL.
8330 - Changed login error messages to be more descriptive.
8331 - remove setting of SO_DEBUG socket option
8332 - Make ftp_getrc() more lenient about multiline responses,
8333 specifically, 230 responses which don't have continuation 230-
8334 on each line). These seem to be all NT FTP servers, and while
8335 perhaps questionable, they appear to be legal by RFC 959.
8336 - Add missing kill_timeout() after transfer to user completes.
8339 *) Fixed problem where a busy server could hang when restarting
8340 after being sent a SIGHUP due to child processes not exiting.
8343 *) Modify mod_include escaping so a '\' only signifies an escaped
8344 character if the next character is one that needs
8345 escaping. [Ben Laurie]
8347 *) Eliminated possible infinite loop in mod_imap when relative URLs are
8348 used with a 'base' directive that does not have a '/' in it.
8349 [Marc Slemko, reported by Onno Witvliet <onno@tc.hsa.nl>]
8351 *) Reduced the default timeout from 1200 seconds to 300, and the
8352 one in the sample configfile from 400 to 300. [Marc Slemko]
8354 *) Stop vbprintf from crashing if given a NULL string pointer;
8355 print (null) instead. [Ken Coar]
8357 *) Don't disable Nagle algorithm if system doesn't have TCP_NODELAY.
8358 [Marc Slemko and Roy Fielding]
8360 *) Fixed problem with mod_cgi-generated internal redirects trying to
8361 read the request message-body twice. [Archie Cobbs and Roy Fielding]
8363 *) Reduced timeout on lingering close, removed possibility of a blocked
8364 read causing the child to hang, and stopped logging of errors if
8365 the socket is not connected (reset by client). [Roy Fielding]
8367 *) Rearranged main child loop to remove duplication of code in
8368 select/accept and keep-alive requests, fixed several bugs regarding
8369 checking scoreboard_image for exit indication and failure to
8370 account for all success conditions and trap all error conditions,
8371 prevented multiple flushes before closing the socket; close the entire
8372 socket buffer instead of just one descriptor, prevent logging of
8373 EPROTO and ECONNABORTED on platforms where supported, and generally
8374 improved readability. [Roy Fielding]
8376 *) Extensive performance improvements. Cleaned up inefficient use of
8377 auto initializers, multiple is_matchexp calls on a static string,
8378 and excessive merging of response_code_strings. [Dean Gaudet]
8380 *) Added double-buffering to mod_include to improve performance on
8381 server-side includes. [Marc Slemko]
8383 *) Several fixes for suexec wrapper. [Randy Terbush]
8384 - Make wrapper work for files on NFS filesystem.
8385 - Fix portability problem of MAXPATHLEN.
8386 - Fix array overrun problem in clean_env().
8387 - Fix allocation of PATH environment variable
8389 *) Removed extraneous blank line is description of mod_status chars.
8392 *) Logging of errors from the call_exec routine simply went nowhere,
8393 since the logfile fd has been closed, so now we send them to stderr.
8394 [Harald T. Alvestrand]
8396 *) Fixed core dump when DocumentRoot is a CGI.
8397 [Ben Laurie, reported by geddis@tesserae.com]
8399 *) Fixed potential file descriptor leak in mod_asis; updated it and
8400 http_core to use pfopen/pfclose instead of fopen/fclose.
8401 [Randy Terbush and Roy Fielding]
8403 *) Fixed handling of unsigned ints in ap_snprintf() on some chips such
8404 as the DEC Alpha which is 64-bit but uses 32-bit ints.
8405 [Dean Gaudet and Ken Coar]
8407 *) Return a 302 response code to the client when sending a redirect
8408 due to a missing trailing '/' on a directory instead of a 301; now
8409 it is cacheable. [Markus Gyger]
8411 *) Fix condition where, if a bad directive occurs in .htaccess, and
8412 sub_request() goes first to this directory, then log_reason() will
8413 SIGSEGV because it doesn't have initialized r->per_dir_config.
8414 [PR#162 from Petr Lampa, fix by Marc Slemko and Dean Gaudet]
8416 *) Fix handling of lang_index in is_variant_better(). This was
8417 causing problems which resulted in the server sending the
8418 wrong language document in some cases. [Petr Lampa]
8420 *) Remove free() from clean_env() in suexec wrapper. This was nuking
8421 the clean environment on some systems.
8423 *) Tweak byteserving code (e.g. serving PDF files) to work around
8424 bugs in Netscape Navigator and Microsoft Internet Explorer.
8425 Emit Content-Length header when sending multipart/byteranges.
8428 *) Port to HI-UX/WE2. [Nick Maclaren]
8430 *) Port to HP MPE operating system for HP 3000 machines
8431 [Mark Bixby <markb@cccd.edu>]
8433 *) Fixed bug which caused a segmentation fault if only one argument
8434 given to RLimit* directives. [Ed Korthof]
8436 *) Continue persistent connection after 204 or 304 response. [Dean Gaudet]
8438 *) Improved buffered output to the client by delaying the flush decision
8439 until the BUFF code is actually about to read the next request.
8440 This fixes a problem introduced in 1.2b5 with clients that send
8441 an extra CRLF after a POST request. Also improved chunked output
8442 performance by combining writes using writev() and removing as
8443 many bflush() calls as possible. NOTE: Platforms without writev()
8444 must add -DNO_WRITEV to the compiler CFLAGS, either in Configuration
8445 or Configure, unless we have already done so. [Dean Gaudet]
8447 *) Fixed mod_rewrite bug which truncated the rewritten URL [Marc Slemko]
8449 *) Fixed mod_info output corruption bug introduced by buffer overflow
8450 fixes. [Dean Gaudet]
8452 *) Fixed http_protocol to correctly output all HTTP/1.1 headers, including
8453 for the special case of a 304 response. [Paul Sutton]
8455 *) Improved handling of TRACE method by bypassing normal method handling
8456 and header parsing routines; fixed Allow response to always allow TRACE.
8459 *) Fixed compiler warnings in the regex library. [Dean Gaudet]
8461 *) Cleaned-up some of the generated HTML. [Ken Coar]
8463 Changes with Apache 1.2b6
8465 *) Allow whitespace in imagemap mapfile coordinates. [Marc Slemko]
8467 *) Fix typo introduced in fix for potential infinite loop around
8468 accept() in child_main(). This change caused the rev to 1.2b6.
8469 1.2b5 was never a public beta.
8471 Changes with Apache 1.2b5
8473 *) Change KeepAlive semantics (On|Off instead of a number), add
8474 MaxKeepAliveRequests directive. [Alexei Kosut]
8476 *) Various NeXT compilation patches, as well as a change in
8477 regex/regcomp.c since that file also used a NEXT define.
8480 *) Allow * to terminate the end of a directory match in mod_dir.
8481 Allows /~* to match for both /~joe and /~joe/. [David Bronder]
8483 *) Don't call can_exec() if suexec_enabled. Calling this requires
8484 scripts executed by the suexec wrapper to be world executable, which
8485 defeats one of the advantages of running the wrapper. [Randy Terbush]
8487 *) Portability Fix: IRIX complained with 'make clean' about *pure* (removed)
8490 *) Migration from sprintf() to snprintf() to avoid buffer
8491 overflows. [Marc Slemko]
8493 *) Provide portable snprintf() implementation (ap_snprintf)
8494 as well as *cvt family. [Jim Jagielski]
8496 *) Portability Fix: NeXT lacks unistd.h so we wrap it's inclusion
8499 *) Remove mod_fastcgi.c from the distribution. This module appears
8500 to be maintained more through the Open Market channels and should
8501 continue to be easily available at http://www.fastcgi.com/
8503 *) Fixed bug in modules/Makefile that wouldn't allow building in more
8504 than one subdirectory (or cleaning, either). [Jeremy Laidman]
8506 *) mod_info assumed that the config files were relative to ServerRoot.
8509 *) CGI scripts called as an error document resulting from failed
8510 CGI execution would hang waiting for POST'ed data. [Rob Hartill]
8512 *) Log reason when mod_dir returns access HTTP_FORBIDDEN
8515 *) Properly check errno to prevent display of a directory index
8516 when server receives a long enough URL to confuse stat().
8519 *) Several security enhancements to suexec wrapper. It is _highly_
8520 recommended that previously installed versions of the wrapper
8521 be replaced with this version. [Randy Terbush, Jason Dour]
8523 - ~user execution now properly restricted to ~user's home
8524 directory and below.
8525 - execution restricted to UID/GID > 100
8526 - restrict passed environment to known variables
8527 - call setgid() before initgroups() (portability fix)
8528 - remove use of setenv() (portability fix)
8530 *) Add HTTP/1.0 response forcing. [Ben Laurie]
8532 *) Add access control via environment variables. [Ben Laurie]
8534 *) Add rflush() function. [Alexei Kosut]
8536 *) remove duplicate pcalloc() call in new_connection().
8538 *) Fix incorrect comparison which could allow number of children =
8539 MaxClients + 1 if less than HARD_SERVER_LIMIT. Also fix potential
8540 problem if StartServers > HARD_SERVER_LIMIT. [Ed Korthof]
8542 *) Updated support for OSes (MachTen, ULTRIX, Paragon, ISC, OpenBSD
8543 AIX PS/2, CONVEXOS. [Jim Jagielski]
8545 *) Replace instances of inet_ntoa() with inet_addr() for ProxyBlock.
8546 It's more portable. [Martin Kraemer]
8548 *) Replace references to make in Makefile.tmpl with $(MAKE).
8551 *) Add ProxyBlock directive w/IP address caching. Add IP address
8552 caching to NoCache directive as well. ProxyBlock works with all
8553 handlers; NoCache now also works with FTP for anonymous logins.
8554 Still more code cleanup. [Chuck Murcko]
8556 *) Add "header parse" API hook [Ben Laurie]
8558 *) Fix byte ordering problems for REMOTE_PORT [Chuck Murcko]
8560 *) suEXEC wrapper was freeing memory that had not been malloc'ed.
8562 *) Correctly allow access and auth directives in <Files> sections in
8563 server config files. [Alexei Kosut]
8565 *) Fix bug with ServerPath that could cause certain files to be not
8566 found by the server. [Alexei Kosut]
8568 *) Fix handling of ErrorDocument so that it doesn't remove a trailing
8569 double-quote from text and so that it properly checks for unsupported
8570 status codes using the new index_of_response interface. [Roy Fielding]
8572 *) Multiple fixes to the lingering_close code in order to avoid being
8573 interrupted by a stray timeout, to avoid lingering on a connection
8574 that has already been aborted or never really existed, to ensure that
8575 we stop lingering as soon as any error condition is received, and to
8576 prevent being stuck indefinitely if the read blocks. Also improves
8577 reporting of error conditions. [Marc Slemko and Roy Fielding]
8579 *) Fixed initialization of parameter structure for sigaction.
8580 [mgyger@itr.ch, Adrian Filipi-Martin]
8582 *) Fixed reinitializing the parameters before each call to accept and
8583 select, and removed potential for infinite loop in accept.
8584 [Roy Fielding, after useful PR from adrian@virginia.edu]
8586 *) Fixed condition where, if a child fails to fork, the scoreboard would
8587 continue to say SERVER_STARTING forever. Eventually, the main process
8588 would refuse to start new children because count_idle_servers() will
8589 count those SERVER_STARTING entries and will always report that there
8590 are enough idle servers. [Phillip Vandry]
8592 *) Fixed bug in bcwrite regarding failure to account for partial writes.
8593 Avoided calling bflush() when the client is pipelining requests.
8594 Removed unnecessary flushes from http_protocol. [Dean Gaudet]
8596 *) Added description of "." mode in server-status [Jim Jagielski]
8598 Changes with Apache 1.2b4
8600 *) Fix possible race condition in accept_mutex_init() that
8601 could leave a small security hole open allowing files to be
8602 overwritten in cases where the server UID has write permissions.
8605 *) Fix awk compatibilty problem in Configure. [Jim Jagielski]
8607 *) Fix portablity problem in util_script where ARG_MAX may not be
8608 defined for some systems.
8610 *) Add changes to allow compilation on Machten 4.0.3 for PowerPC.
8613 *) OS/2 changes to support an MMAP style scoreboard file and UNIX
8614 style magic #! token for better script portability. [Garey Smiley]
8616 *) Fix bug in suexec wrapper introduced in b3 that would cause failed
8617 execution for ~userdir CGI. [Jason Dour]
8619 *) Fix initgroups() business in suexec wrapper. [Jason Dour]
8621 *) Fix month off by one in suexec wrapper logging.
8623 Changes with Apache 1.2b3:
8625 *) Fix error in mod_cgi which could cause resources not to be properly
8626 freed, or worse. [Dean Gaudet]
8628 *) Fix find_string() NULL pointer dereference. [Howard Fear]
8630 *) Add set_flag_slot() at the request of Dirk and others.
8633 *) Sync mod_rewrite with patch level 10. [Ralf Engelschall]
8635 *) Add changes to improve the error message given for invalid
8636 ServerName parameters. [Dirk vanGulik]
8638 *) Add "Authoritative" directive for Auth modules that don't
8639 currently have it. This gives admin control to assign authoritative
8640 control to an authentication scheme and allow "fall through" for
8641 those authentication modules that aren't "Authoritative" thereby
8642 allowing multiple authentication mechanisms to be chained.
8645 *) Remove requirement for ResourceConfig/AccessConfig if not using
8646 the three config file layout. [Randy Terbush]
8648 *) Add PASV mode to mod_proxy FTP handler. [Chuck Murcko]
8650 *) Changes to suexec wrapper to fix the following problems:
8651 1. symlinked homedirs will kill ~userdirs.
8652 2. initgroups() on Linux 2.0.x clobbers gr->grid.
8653 3. CGI command lines paramters problems
8654 4. pw-pwdir for "docroot check" still the httpd user's pw record.
8655 [Randy Terbush, Jason Dour]
8657 *) Change create_argv() to accept variable arguments. This fixes
8658 a problem where arguments were not getting passed to the CGI via
8659 argv[] when the suexec wrapper was active. [Randy Terbush, Jake Buchholz]
8661 *) Collapse multiple slashes in path URLs to properly apply
8662 handlers defined by <Location>. [Alexei Kosut]
8664 *) Define a sane set of DEFAULT_USER and DEFAULT_GROUP values for AIX.
8666 *) Improve the accuracy of request duration timings by setting
8667 r->request_time in read_request_line() instead of read_request().
8670 *) Reset timeout while reading via get_client_block() in mod_cgi.c
8671 Fixes problem with timed out transfers of large files. [Rasmus Lerdorf]
8673 *) Add the ability to pass different Makefile.tmpl files to Configure
8674 using the -make flag. [Rob Hartill]
8676 *) Fix coredump triggered when sending a SIGHUP to the server caused
8677 by an assertion failure, in turn caused by an uninitialised field in a
8681 *) Add FILEPATH_INFO variable to CGI environment, which is equal to
8682 PATH_INFO from previous versions of Apache (in certain situations,
8683 Apache 1.2's PATH_INFO will be different than 1.1's). [Alexei Kosut]
8684 [later removed in 1.2b11]
8686 *) Add rwrite() function to API to allow for sending strings of
8687 arbitrary length. [Doug MacEachern]
8689 *) Remove rlim_t typedef for NetBSD. Do older versions need this?
8691 *) Defined rlim_t and WANTHSREGEX=yes and fixed waitpid() substitute for
8692 NeXT. [Jim Jagielski]
8694 *) Removed recent modification to promote the status code on internal
8695 redirects, since the correct fix was to change the default log format
8696 in mod_log_config so that it outputs the original status. [Rob Hartill]
8698 Changes with Apache 1.2b2:
8700 *) Update set_signals() to use sigaction() for setting handlers.
8701 This appears to fix a re-entrant problem in the seg_fault()
8702 bus_error() handlers. [Randy Terbush]
8704 *) Changes to allow mod_status compile for OS/2 [Garey Smiley]
8706 *) changes for DEC AXP running OSF/1 v3.0. [Marc Evans]
8708 *) proxy_http.c bugfixes: [Chuck Murcko]
8709 1) fixes possible NULL pointer reference w/NoCache
8710 2) fixes NoCache behavior when using ProxyRemote (ProxyRemote
8711 host would cache nothing if it was in the local domain,
8712 and the local domain was in the NoCache list)
8713 3) Adds Host: header when not available
8714 4) Some code cleanup and clarification
8716 *) mod_include.c bugfixes:
8717 1) Fixed an ommission that caused include variables to not
8718 be parsed in config errmsg directives [Howard Fear]
8719 2) Remove HAVE_POSIX_REGEX cruft [Alexei Kosut]
8720 3) Patch to fix compiler warnings [perrot@lal.in2p3.fr]
8721 4) Allow backslash-escaping to all quoted text
8722 [Ben Yoshino <ben@wiliki.eng.hawaii.edu>]
8723 5) Pass variable to command line if not set in XSSI's env
8726 *) Fix infinite loop when processing Content-language lines in
8727 type-map files. [Alexei Kosut]
8729 *) Closed file-globbing hole in test-cgi script. [Brian Behlendorf]
8731 *) Fixed problem in set_[user|group] that prevented CGI execution
8732 for non-virtualhosts when suEXEC was enabled. [Randy Terbush]
8734 *) Added PORTING information file. [Jim Jagielski]
8736 *) Added definitions for S_IWGRP and S_IWOTH to conf.h [Ben Laurie]
8738 *) Changed default group to "nogroup" instead of "nobody" [Randy Terbush]
8740 *) Fixed define typo of FCNTL_SERIALIZED_ACCEPT where
8741 USE_FCNTL_SERIALIZED_ACCEPT was intended.
8743 *) Fixed additional uses of 0xffffffff where INADDR_NONE was intended,
8744 which caused problems of systems where socket s_addr is >32bits.
8746 *) Added comment to explain (r->chunked = 1) side-effect in
8747 http_protocol.c [Roy Fielding]
8749 *) Replaced use of index() in mod_expires.c with more appropriate
8750 and portable isdigit() test. [Ben Laurie]
8752 *) Updated Configure for ...
8753 OS/2 (DEF_WANTHSREGEX=yes, other code changes)
8754 *-dg-dgux* (bad pattern match)
8755 QNX (DEF_WANTHSREGEX=yes)
8756 *-sunos4* (DEF_WANTHSREGEX=yes, -DUSEBCOPY)
8759 and added some user diagnostic info. [Ben Laurie]
8761 *) In helpers/CutRule, replaced "cut" invocation with "awk" invocation
8762 for better portability. [Jim Jagielski]
8764 *) Updated helpers/GuessOS for ...
8765 SCO 5 (recognize minor releases)
8766 SCO UnixWare (braindamaged uname, whatever-whatever-unixware2)
8767 SCO UnixWare 2.1.1 (requires a separate set of #defines in conf.h)
8768 IRIX64 (-sgi-irix64)
8769 ULTRIX (-unknown-ultrix)
8770 SINIX (-whatever-sysv4)
8771 NCR Unix (-ncr-sysv4)
8772 and fixed something in helpers/PrintPath [Ben Laurie]
8774 Changes with Apache 1.2b1
8776 *) Not listed. See <http://www.apache.org/docs/new_features_1_2.html>
8778 Changes with Apache 1.1.1
8780 *) Fixed bug where Cookie module would make two entries in the
8781 logfile for each access [Mark Cox]
8783 *) Fixed bug where Redirect in .htaccess files would cause memory
8784 leak. [Nathan Neulinger]
8786 *) MultiViews now works correctly with AddHandler [Alexei Kosut]
8788 *) Problems with mod_auth_msql fixed [Dirk vanGulik]
8790 *) Fix misspelling of "Anonymous_Authorative" directive in mod_auth_anon.
8792 Changes with Apache 1.1.0
8794 *) Bring NeXT support up to date. [Takaaki Matsumoto]
8796 *) Bring QNX support up to date. [Ben Laurie]
8798 *) Make virtual hosts default to main server keepalive parameters.
8799 [Alexei Kosut, Ben Laurie]
8801 *) Allow ScanHTMLTitles to work with lowercase <title> tags. [Alexei Kosut]
8803 *) Fix missing address family for connect, also remove unreachable statement
8804 in mod_proxy. [Ben Laurie]
8806 *) mod_env now turned on by default in Configuration.tmpl.
8808 *) Bugs which were fixed:
8809 a) yet more mod_proxy bugs [Ben Laurie]
8810 b) CGI works again with inetd [Alexei Kosut]
8811 c) Leading colons were stripped from passwords [osm@interguide.com]
8812 d) Another fix to multi-method Limit problem [jk@tools.de]
8814 Changes with Apache 1.1b4
8816 *) r->bytes_sent variable restored. [Robert Thau]
8818 *) Previously broken multi-method <Limit> parsing fixed. [Robert Thau]
8820 *) More possibly unsecure programs removed from the support directory.
8822 *) More mod_auth_msql authentication improvements.
8824 *) VirtualHosts based on Host: headers no longer conflict with the
8827 *) OS/2 compatibility enhancements. [Gary Smiley]
8829 *) POST now allowed to directory index CGI scripts.
8831 *) Actions now work with files of the default type.
8833 *) Bugs which were fixed:
8834 a) more mod_proxy bugs
8835 b) early termination of inetd requests
8836 c) compile warnings on several systems
8837 d) problems when scripts stop reading output early
8839 Changes with Apache 1.1b3
8841 *) Much of cgi-bin and all of cgi-src has been removed, due to
8842 various security holes found and that we could no longer support
8845 *) The "Set-Cookie" header is now special-cased to not merge multiple
8846 instances, since certain popular browsers can not handle multiple
8847 Set-Cookie instructions in a single header. [Paul Sutton]
8849 *) rprintf() added to buffer code, occurrences of sprintf removed.
8852 *) CONNECT method for proxy module, which means tunneling SSL should work.
8853 (No crypto needed) Also a NoCache config directive.
8855 *) Several API additions: pstrndup(), table_unset() and get_token()
8856 functions now available to modules.
8858 *) mod_imap fixups, in particular Location: headers are now complete
8861 *) New "info" module which reports on installed module set through a
8862 special URL, a la mod_status.
8864 *) "ServerPath" directive added - allows for graceful transition
8865 for Host:-header-based virtual hosts.
8867 *) Anonymous authentication module improvements.
8869 *) MSQL authentication module improvements.
8871 *) Status module design improved - output now table-based. [Ben Laurie]
8873 *) htdigest utility included for use with digest authentication
8876 *) mod_negotiation: Accept values with wildcards to be treated with
8877 less priority than those without wildcards at the same quality
8878 value. [Alexei Kosut]
8880 *) Bugs which were fixed:
8881 a) numerous mod_proxy bugs
8882 b) CGI early-termination bug [Ben Laurie]
8883 c) Keepalives not working with virtual hosts
8884 d) RefererIgnore problems
8885 e) closing fd's twice in mod_include (causing core dumps on
8886 Linux and elsewhere).
8888 Changes with Apache 1.1b2
8891 a) core dumps in mod_digest
8892 b) truncated hostnames/ip address in the logs
8893 c) relative URL's in mod_imap map files
8895 Changes with Apache 1.1b1
8897 *) Not listed. See <http://www.apache.org/docs/new_features_1_1.html>
8899 Changes with Apache 1.0.3
8901 *) Internal redirects which occur in mod_dir.c now preserve the
8902 query portion of a request (the bit after the question mark).
8905 *) Escape active characters '<', '>' and '&' in html output in
8906 directory listings, error messages and redirection links.
8909 *) Apache will now work with LynxOS 2.3 and later [Steven Watt]
8911 *) Fix for POSIX compliance in waiting for processes in alloc.c.
8914 *) setsockopt no longer takes a const declared argument [Martijn Koster]
8916 *) Reset timeout timer after each successful fwrite() to the network.
8917 This patch adds a reset_timeout() procedure that is called by
8918 send_fd() to reset the timeout ever time data is written to the net.
8921 *) timeout() signal handler now checks for SIGPIPE and reports
8922 lost connections in a more user friendly way. [Rob Hartill]
8924 *) Location of the "scoreboard" file which used to live in /tmp is
8925 now configurable (for OSes that can't use mmap) via ScoreBoardFile
8926 which works similar to PidFile (in httpd.conf) [Rob Hartill]
8928 *) Include sys/resource.h in the correct place for SunOS4 [Sameer Parekh]
8930 *) the pstrcat call in mod_cookies.c didn't have an ending NULL,
8931 which caused a SEGV with cookies enabled
8933 *) Output warning when MinSpareServers is set to <= 0 and change it to 1
8936 *) Log the UNIX textual error returned by some system calls, in
8937 particular errors from accept() [David Robinson]
8939 *) Add strerror function to util.c for SunOS4 [Randy Terbush]
8941 Changes with Apache 1.0.2
8943 *) patch to get Apache compiled on UnixWare 2.x, recommended as
8944 a temporary measure, pending rewrite of rfc931.c. [Chuck Murcko]
8946 *) Fix get_basic_auth_pw() to set the auth_type of the request.
8949 *) past changes to http_config.c to only use the
8950 setrlimit function on systems defining RLIMIT_NOFILE
8951 broke the feature on SUNOS4. Now defines HAVE_RESOURCE
8952 for SUNOS and prototypes the needed functions.
8954 *) Remove uses of MAX_STRING_LEN/HUGE_STRING_LEN from several routines.
8957 *) Fix use of pointer to scratch memory. [Cliff Skolnick]
8959 *) Merge multiple headers from CGI scripts instead of taking last
8960 one. [David Robinson]
8962 *) Add support for SCO 5. [Ben Laurie]
8964 Changes with Apache 1.0.1
8966 *) Silence mod_log_referer and mod_log_agent if not configured
8969 *) Recursive includes can occur if the client supplies PATH_INFO data
8970 and the server provider uses relative links; as file.html
8971 relative to /doc.shtml/pathinfo is /doc.shtml/file.html. [David Robinson]
8973 *) The replacement for initgroups() did not call {set,end}grent(). This
8974 had two implications: if anything else used getgrent(), then
8975 initgroups() would fail, and it was consuming a file descriptor.
8978 *) On heavily loaded servers it was possible for the scoreboard to get
8979 out of sync with reality, as a result of a race condition.
8980 The observed symptoms are far more Apaches running than should
8981 be, and heavy system loads, generally followed by catastrophic
8982 system failure. [Ben Laurie]
8984 *) Fix typo in license. [David Robinson]
8986 Changes with Apache 1.0.0 23 Nov 1995
8988 *) Not listed. See <http://www.apache.org/docs/new_features_1_0.html>
8990 Changes with Apache 0.8.16 05 Nov 1995
8992 *) New man page for 'httpd' added to support directory [David Robinson]
8994 *) .htgroup files can have more than one line giving members for a
8995 given group (each must have the group name in front), for NCSA
8996 back-compatibility [Robert Thau]
8998 *) Mutual exclusion around accept() is on by default for SVR4 systems
8999 generally, since they generally can't handle multiple processes in
9000 accept() on the same socket. This should cure flaky behavior on
9001 a lot of those systems. [David Robinson]
9003 *) AddType, AddEncoding, and AddLanguage directives take multiple
9004 extensions on a single command line [David Robinson]
9006 *) UserDir can be disabled for a given virtual host by saying
9007 "UserDir disabled" in the <VirtualHost> section --- it was a bug
9008 that this didn't work. [David Robinson]
9010 *) Compiles on QNX [Ben Laurie]
9012 *) Corrected parsing of ctime time format [David Robinson]
9014 *) httpd does a perror() before exiting if it can't log its pid
9015 to the PidFile, to make diagnosing the error a bit easier.
9018 *) <!--#include file="..."--> can no longer include files in the
9019 parent directory, for NCSA back-compatibility. [David Robinson]
9021 *) '~' is *not* escaped in URIs generated for directory listings
9024 *) Eliminated compiler warning in the imagemap module [Randy Terbush]
9026 *) Fixed bug involving handling URIs with escaped %-characters
9027 in redirects [David Robinson]
9029 Changes with Apache 0.8.15 14 Oct 1995
9031 *) Switched to new, simpler license
9033 *) Eliminated core dumps with improperly formatted DBM group files [Mark Cox]
9035 *) Don't allow requests for ordinary files to have PATH_INFO [Ben Laurie]
9037 *) Reject paths containing %-escaped '%' or null characters [David Robinson]
9039 *) Correctly handles internal redirects to files with names containing '%'
9042 *) Repunctuated some error messages [Aram Mirzadeh, Andrew Wilson]
9044 *) Use geteuid() rather than getuid() to see if we have root privilege,
9045 so that server correctly resets privilege if run setuid root. [Andrew
9048 *) Handle ftp: and telnet: URLs correctly in imagemaps (built-in module)
9051 *) Fix relative URLs in imagemap files [Randy Terbush]
9053 *) Somewhat better fix for the old "Alias /foo/ /bar/" business
9056 *) Don't repeatedly open the ErrorLog if a bunch of <VirtualHost>
9057 entries all name the same one. [David Robinson]
9059 *) Fix directory listings with filenames containing unusual characters
9062 *) Better URI-escaping for generated URIs in directories with filenames
9063 containing unusual characters [Ben Laurie]
9065 *) Fixed potential FILE* leak in http_main.c [Ben Laurie]
9067 *) Unblock alarms on error return from spawn_child() [David Robinson]
9069 *) Sample Config files have extra note for SCO users [Ben Laurie]
9071 *) Configuration has note for HP-UX users [Rob Hartill]
9073 *) Eliminated some bogus Linux-only #defines in conf.h [Aram Mirzadeh]
9075 *) Nuked bogus #define in httpd.h [David Robinson]
9077 *) Better test for whether a system has setrlimit() [David Robinson]
9079 *) Calls update_child_status() after reopen_scoreboard() [David Robinson]
9081 *) Doesn't send itself SIGHUP on startup when run in the -X debug-only mode
9084 Changes with Apache 0.8.14 19 Sep 1995
9086 *) Compiles on SCO ODT 3.0 [Ben Laurie]
9088 *) AddDescription works (better) [Ben Laurie]
9090 *) Leaves an intelligible error diagnostic when it can't set group
9091 privileges on standalone startup [Andrew Wilson]
9093 *) Compiles on NeXT again --- the 0.8.13 RLIMIT patch was failing on
9094 that machine, which claims to be BSD but does not support RLIMIT.
9097 *) gcc -Wall no longer complains about an unused variable when util.c
9098 is compiled with -DMINIMAL_DNS [Andrew Wilson]
9100 *) Nuked another compiler warning for -Wall on Linux [Aram Mirzadeh]
9102 Changes with Apache 0.8.13 07 Sep 1995
9104 *) Make IndexIgnore *work* (ooops) [Jarkko Torppa]
9106 *) Have built-in imagemap code recognize & honor Point directive [James
9109 *) Generate cleaner directory listings in directories with a mix of
9110 long and short filenames [Rob Hartill]
9112 *) Properly initialize dynamically loaded modules [Royston Shufflebotham]
9114 *) Properly default ServerName for virtual servers [Robert Thau]
9116 *) Rationalize handling of BSD in conf.h and elsewhere [Randy Terbush,
9117 Paul Richards and a cast of thousands...]
9119 *) On self-identified BSD systems (we don't try to guess any more),
9120 allocate a few extra file descriptors per virtual host with setrlimit,
9121 if we can, to avoid running out. [Randy Terbush]
9123 *) Write 22-character lock file name into buffer with enough space
9124 on startup [Konstantin Olchanski]
9126 *) Use archaic setpgrp() interface on NeXT, which requires it [Brian
9129 *) Suppress -Wall warning by casting const away in util.c [Aram Mirzadeh]
9131 *) Suppress -Wall warning by initializing variable in negotiation code
9132 [Tobias Weingartner]
9134 Changes with Apache 0.8.12 31 Aug 1995
9136 *) Doesn't pause three seconds after including a CGI script which is
9137 too slow to die off (this is done by not even trying to kill off
9138 subprocesses, including the SIGTERM/pause/SIGKILL routine, until
9139 after the entire document has been processed). [Robert Thau]
9141 *) Doesn't do SSI if Options Includes is off. (Ooops). [David Robinson]
9143 *) Options IncludesNoExec allows inclusion of at least text/* [Roy Fielding]
9145 *) Allows .htaccess files to override <Directory> sections naming the
9146 same directory [David Robinson]
9148 *) Removed an efficiency hack in sub_req_lookup_uri which was
9149 causing certain extremely marginal cases (e.g., ScriptAlias of a
9150 *particular* index.html file) to fail. [David Robinson]
9152 *) Doesn't log an error when the requested URI requires
9153 authentication, but no auth header line was supplied by the
9154 client; this is a normal condition (the client doesn't no auth is
9155 needed here yet). [Robert Thau]
9157 *) Behaves more sanely when the name server loses its mind [Sean Welch]
9159 *) RFC931 code compiles cleanly on old BSDI releases [Randy Terbush]
9161 *) RFC931 code no longer passes out name of prior clients on current
9162 requests if the current request came from a server that doesn't
9163 do RFC931. [David Robinson]
9165 *) Configuration script accepts "Module" lines with trailing whitespace.
9168 *) Cleaned up compiler warning from mod_access.c [Robert Thau]
9170 *) Cleaned up comments in mod_cgi.c [Robert Thau]
9172 Changes with Apache 0.8.11 24 Aug 1995
9174 *) Wildcard <Directory> specifications work. [Robert Thau]
9176 *) Doesn't loop for buggy CGI on Solaris [Cliff Skolnick]
9178 *) Symlink checks (FollowSymLinks off, or SymLinkIfOwnerMatch) always check
9179 the file being requested itself, in addition to the directories leading
9180 up to it. [Robert Thau]
9182 *) Logs access failures due to symlink checks or invalid client address
9183 in the error log [Roy Fielding, Robert Thau]
9185 *) Symlink checks deal correctly with systems where lstat of
9186 "/path/to/some/link/" follows the link. [Thau, Fielding]
9188 *) Doesn't reset DirectoryIndex to 'index.html' when
9189 other directory options are set in a .htaccess file. [Robert Thau]
9191 *) Clarified init code and nuked bogus warning in mod_access.c
9194 *) Corrected several directives in sample srm.conf
9195 --- includes corrections to directory indexing icon-related directives
9196 (using unknown.gif rather than unknown.xbm as the DefaultIcon, doing
9197 icons for encodings right, and turning on AddEncoding by default).
9200 *) Corrected descriptions of args to AddIcon and AddAlt in command table
9203 *) INSTALL & README mention "contributed modules" directory [Brian
9206 *) Fixed English in the license language... "for for" --> "for".
9209 *) Fixed ScriptAlias/Alias interaction by moving ScriptAlias handling to
9210 mod_alias.c, merging it almost completely with handling of Alias, and
9211 adding a 'notes' field to the request_rec which allows the CGI module
9212 to discover whether the Alias module has put this request through
9213 ScriptAlias (which it needs to know for back-compatibility, as the old
9214 NCSA code did not check Options ExecCGI in ScriptAlias directories).
9217 Changes with Apache 0.8.10 18 Aug 1995
9219 *) AllowOverride applies to the named directory, and not just
9220 subdirectories. [David Robinson]
9222 *) Do locking for accept() exclusion (on systems that need it)
9223 using a special file created for the purpose in /usr/tmp, and
9224 not the error log; using the error log causes real problems
9225 if it's NFS-mounted; this is known to be the cause of a whole
9226 lot of "server hang" problems with Solaris. [David Robinson;
9227 thanks to Merten Schumann for help diagnosing the problem].
9229 Changes with Apache 0.8.9 12 Aug 1995
9231 *) Compiles with -DMAXIMUM_DNS ---- ooops! [Henrik Mortensen]
9233 *) Nested includes see environment variables of the including document,
9234 for NCSA bug-compatibility (some sites have standard footer includes
9235 which try to print out the last-modified date). [Eric Hagberg/Robert
9238 *) <!--exec cgi="/some/uri/here"--> always treats the item named by the
9239 URI as a CGI script, even if it would have been treated as something
9240 else if requested directly, for NCSA back-compatibility. (Note that
9241 this means that people who know the name of the script can see the
9242 code just by asking for it). [Robert Thau]
9244 *) New version of dbmmanage script included in support directory as
9247 *) Check if scoreboard file couldn't be opened, and say so, rather
9248 then going insane [David Robinson]
9250 *) POST to CGI works on A/UX [Jim Jagielski]
9252 *) AddIcon and AddAlt commands work properly [Rob Hartill]
9254 *) NCSA server push works properly --- the Arena bug compatibility
9255 workaround, which broke it, is gone (use -DARENA_BUG_WORKAROUND
9256 if you still want the workaround). [Rob Hartill]
9258 *) If client didn't submit any Accept-encodings, ignore encodings in
9259 content negotiation. (NB this will all have to be reworked anyway
9260 for the new HTTP draft). [Florent Guillaume]
9262 *) Don't dump core when trying to log timed-out requests [Jim Jagielski]
9264 *) Really honor CacheNegotiatedDocs [Florent Guillaume]
9266 *) Give Redirect priority over Alias, for NCSA bug compatibility
9269 *) Correctly set PATH_TRANSLATED in all cases from <!--#exec cmd=""-->,
9270 paralleling earlier bug fix for CGI [David Robinson]
9272 *) If DBM auth is improperly configured, report a server error and don't
9275 *) Deleted FCNTL_SERIALIZED_ACCEPTS from conf.h entry for A/UX;
9276 it seems to work well enough without it (even in a 10 hits/sec
9277 workout), and the overhead for the locking under A/UX is
9278 alarmingly high (though it is very low on other systems).
9279 [Eric Hagberg, Jim Jagielski]
9281 *) Fixed portability problems with mod_cookies.c [Cliff Skolnick]
9283 *) Further de-Berklize mod_cookies.c; change the bogus #include. [Brian
9284 Behlendorf/Eric Hagberg]
9286 *) More improvements to default Configuration for A/UX [Jim Jagielski]
9288 *) Compiles clean on NEXT [Rob Hartill]
9290 *) Compiles clean on SGI [Robert Thau]
9292 Changes with Apache 0.8.8 08 Aug 1995
9294 *) SunOS library prototypes now never included unless explicitly
9295 requested in the configuration (via -DSUNOS_LIB_PROTOTYPES);
9296 people using GNU libc on SunOS are screwed by prototypes for the
9299 (Those who wish to compile clean with gcc -Wall on a standard
9300 SunOS setup need the prototypes, and may obtain them using
9301 -DSUNOS_LIB_PROTOTYPES. Those wishing to use -Wall on a system
9302 with nonstandard libraries are presumably competent to make their
9305 *) Strips trailing '/' characters off both args to the Alias command,
9306 to make 'Alias /foo/ /bar/' work.
9308 Changes with Apache 0.8.7 03 Aug 1995
9310 *) Don't hang when restarting with a child from 'TransferLog "|..."' running
9311 [reported by David Robinson]
9313 *) Compiles clean on OSF/1 [David Robinson]
9315 *) Added some of the more recent significant changes (AddLanguage stuff,
9316 experimental LogFormat support) to CHANGES file in distribution root
9319 Changes with Apache 0.8.6 02 Aug 1995
9321 *) Deleted Netscape reload workaround --- it's in violation of HTTP specs.
9322 (If you actually wanted a conditional GET which bypassed the cache, you
9323 couldn't get it). [Reported by Roy Fielding]
9325 *) Properly terminate headers on '304 Not Modified' replies to conditional
9326 GETs --- no browser we can find cares much, but the CERN proxy chokes.
9327 [Reported by Cliff Skolnick; fix discovered independently by Rob Hartill]
9329 *) httpd -v doesn't call itself "Shambhala". [Reported by Chuck Murcko]
9331 *) SunOS lib-function prototypes in conf.h conditionalized on __GNUC__,
9332 not __SUNPRO_C (they're needed to quiet gcc -Wall, but acc chokes on 'em,
9333 and older versions don't set the __SUNPRO_C preprocessor variable). On
9334 all other systems, these are never used anyway. [Reported by Mark Cox].
9336 *) Scoreboard file (/tmp/htstatus.*) no longer publically writable.
9338 Changes with Apache 0.8.5 01 Aug 1995
9340 *) Added last-minute configurable log experiment, as optional module
9342 *) Correctly set r->bytes_sent for HTTP/0.9 requests, so they get logged
9343 properly. (One-line fix to http_protocol.c).
9345 *) Work around bogus behavior when reloading from Netscape.
9346 It's Netscape's bug --- for some reason they expect a request with
9347 If-modified-since: to not function as a conditional GET if it also
9348 comes with Pragma: no-cache, which is way out of line with the HTTP
9349 spec (according to Roy Fielding, the redactor).
9351 *) Added parameter to set maximum number of server processes.
9353 *) Added patches to make it work on A/UX. A/UX is *weird*. [Eric Hagberg,
9356 *) IdentityCheck bugfix [Chuck Murcko].
9358 *) Corrected cgi-src/Makefile entry for new imagemap script. [Alexei Kosut]
9360 *) More sample config file corrections; add extension to AddType for
9361 *.asis, move AddType generic description to its proper place, and
9362 fix miscellaneous typos. [ Alexei Kosut ]
9364 *) Deleted the *other* reference to the regents from the Berkeley
9365 legal disclaimer (everyplace).
9367 *) Nuked Shambhala name from src/README; had already cleaned it out
9370 Changes with Apache 0.8.4
9372 *) Changes to server-pool management parms --- renamed current
9373 StartServers to MinSpareServers, created separate StartServers
9374 parameter which means what it says, and renamed MaxServers to
9375 MaxSpareServers (though the old name still works, for NCSA 1.4
9376 back-compatibility). The old names were generally regarded as
9377 too confusing. Also altered "docs" in sample config files.
9379 *) More improvements to default config files ---
9380 sample directives (commented out) for XBitHack, BindAddress,
9381 CacheNegotiatedDocs, VirtualHost; decent set of AddLanguage
9382 defaults, AddTypes for send-as-is and imagemap magic types, and
9383 improvements to samples for DirectoryIndex [Alexei Kosut]
9385 *) Yet more improvements to default config files --- changes to
9386 Alexei's sample AddLanguage directives, and sample LanguagePriority
9387 [ Florent Guillaume ]
9389 *) Set config file locations properly if not set in httpd.conf
9392 *) Don't escape URIs in internal redirects multiple times; don't
9393 do that when translating PATH_INFO to PATH_TRANSLATED either.
9396 *) Corrected spelling of "Required" in 401 error reports [Andrew Wilson]
9398 Changes with Apache 0.8.3
9400 *) Edited distribution README to *briefly* summarize installation
9401 procedures, and give a pointer to the INSTALL file in the src/
9404 *) Upgraded imagemap script in cgi-bin to 1.8 version from more
9405 recent NCSA distributions.
9407 *) Bug fix to previous bug fix --- if .htaccess file and <Directory>
9408 exist for the same directory, use both and don't segfault. [Reported
9411 *) Proper makefile dependencies [David Robinson]
9413 *) Note (re)starts in error log --- reported by Rob Hartill.
9415 *) Only call no2slash() after get_path_info() has been done, to
9416 preserve multiple slashes in the PATH_INFO [NCSA compatibility,
9417 reported by Andrew Wilson, though this one is probably a real bug]
9419 *) Fixed mod_imap.c --- relative paths with base_uri referer don't
9420 dump core when Referer is not supplied. [Randy Terbush]
9422 *) Lightly edited sample config files to refer people to our documentation
9423 instead of NCSA's, and to list Rob McCool as *original* author (also
9424 deleted his old, and no doubt non-functional email address). Would be
9425 nice to have examples of new features...
9427 Changes with Apache 0.8.2 19 Jul 1995
9429 *) Added AddLanuage code [Florent Guillaume]
9431 *) Don't say "access forbidden" when a CGI script is not found. [Mark Cox]
9433 *) All sorts of problems when MultiViews finds a directory. It would
9434 be nice if mod_dir.c was robust enough to handle that, but for now,
9435 just punt. [reported by Brian Behlendorf]
9437 *) Wait for all children on restart, to make sure that the old socket
9438 is gone and we can reopen it. [reported by Randy Terbush]
9440 *) Imagemap module is enabled in default Configuration
9442 *) RefererLog and UserAgentLog modules properly default the logfile
9445 *) Mark Cox's mod_cookies added to the distribution as an optional
9446 module (commented out in the default Configuration, and noted as
9447 an experiment, along with mod_dld). [Mark Cox]
9449 *) Compiles on ULTRIX (a continuing battle...). [Robert Thau]
9451 *) Fixed nasty bug in SIGTERM handling [reported by Randy Terbush]
9453 *) Changed "Shambhala" to "Apache" in API docs. [Robert Thau]
9455 *) Added new, toothier legal disclaimer. [Robert Thau; copied from BSD
9458 Changes with Apache 0.8.1
9460 *) New imagemap module [Randy Terbush]
9462 *) Replacement referer log module with NCSA-compatible RefererIgnore
9463 [Matthew Gray again]
9465 *) Don't mung directory listings with very long filenames.
9468 Changes with Apache 0.8.0 (nee Shambhala 0.6.2) 16 Jul 1995
9470 *) New config script. See INSTALL for info. [Robert Thau]
9472 *) Scoreboard mechanism for regulating the number of extant server
9473 processes. MaxServers and StartServers defaults are the same as
9474 for NCSA, but the meanings are slightly different. (Actually,
9475 I should probably lower the MaxServers default to 10).
9477 Before asking for a new connection, each server process checks
9478 the number of other servers which are also waiting for a
9479 connection. If there are more than MaxServers, it quietly dies
9480 off. Conversely, every second, the root, or caretaker, process
9481 looks to see how many servers are waiting for a new connection;
9482 if there are fewer than StartServers, it starts a new one. This
9483 does not depend on the number of server processes already extant.
9484 The accounting is arranged through a "scoreboard" file, named
9485 /tmp/htstatus.*, on which each process has an independent file
9486 descriptor (they need to seek without interference).
9488 The end effect is that MaxServers is the maximum number of
9489 servers on an *inactive* server machine, but more will be forked
9490 off to handle unusually heavy loads (or unusually slow clients);
9491 these will die off when they are no longer needed --- without
9492 reverting to the overhead of full forking operation. There is a
9493 hard maximum of 150 server processes compiled in, largely to
9494 avoid forking out of control and dragging the machine down.
9495 (This is arguably too high).
9497 In my server endurance tests, this mechanism did not appear to
9498 impose any significant overhead, even after I forced it to put the
9499 scoreboard file on a normal filesystem (which might have more
9500 overhead than tmpfs). [Robert Thau]
9502 *) Set HTTP_FOO variables for SSI <!--#exec cmd-->s, not just CGI scripts.
9505 *) Read .htaccess files even in directory with <Directory> section.
9506 (Former incompatibility noted on mailing list, now fixed). [Robert
9509 *) "HEAD /" gives the client a "Bad Request" error message, rather
9510 than trying to send no body *and* no headers. [Cliff Skolnick].
9512 *) Don't produce double error reports for some very obscure cases
9513 mainly involving auth configuration (the "all modules decline to
9514 handle" case which is a sure sign of a server bug in most cases,
9515 but also happens when authentication is badly misconfigured).
9518 *) Moved FCNTL_SERIALIZED_ACCEPT defines into conf.h (that's what
9519 it's *for*, and this sort of thing really shouldn't be cluttering
9520 up the Makefile). [Robert Thau]
9522 *) Incidental code cleanups in http_main.c --- stop dragging
9523 sa_client around; just declare it where used. [Robert Thau]
9525 *) Another acc-related fix. (It doesn't like const char
9526 in some places...). [Mark Cox]
9528 Changes with Shambhala 0.6.1 13 Jul 1995
9530 *) Fixed auth_name-related typos in http_core.c [Brian Behlendorf]
9531 Also, fixed auth typo in http_protocol.c unmasked by this fix.
9533 *) Compiles clean with acc on SunOS [Paul Sutton]
9535 *) Reordered modules in modules.c so that Redirect takes priority
9536 over ScriptAlias, for NCSA bug-compatibility [Rob Hartill] ---
9537 believe it or not, he has an actual site with a ScriptAlias and
9538 a Redirect declared for the *exact same directory*. Even *my*
9539 compatibility fetish wouldn't motivate me to fix this if the fix
9540 required any effort, but it doesn't, so what the hey.
9542 *) Fixed to properly default several server_rec fields for virtual
9543 servers from the corresponding fields in the main server_rec.
9544 [Cliff Skolnick --- 'port' was a particular irritant].
9546 *) No longer kills off nph- child processes before they are
9547 finished sending output. [Matthew Gray]
9549 Changes with Shambhala 0.6.0 10 Jul 1995
9551 *) Two styles of timeout --- hard and soft. soft_timeout()s just put
9552 the connection to the client in an "aborted" state, but otherwise
9553 allow whatever handlers are running to clean up. hard_timeout()s
9554 abort the request in progress completely; anything not tied to some
9555 resource pool cleanup will leak. They're still around because I
9556 haven't yet come up with a more elegant way of handling
9557 timeouts when talking to something that isn't the client. The
9558 default_handler and the dir_handler now use soft timeouts, largely
9559 so I can test the feature. [Robert Thau]
9561 *) TransferLog "| my_postprocessor ..." seems to be there. Note that
9562 the case of log handlers dying prematurely is probably handled VERY
9563 gracelessly at this point, and if the logger stops reading input,
9564 the server will hang. (It is known to correctly restart the
9565 logging process on server restart; this is (should be!) going through
9566 the same SIGTERM/pause/SIGKILL routine used to ding an errant CGI
9567 script). [Robert Thau]
9569 *) asis files supported (new module). [Robert Thau]
9571 *) IdentityCheck code is compiled in, but has not been tested. (I
9572 don't know anyone who runs identd). [Robert Thau]
9574 *) PATH_INFO and PATH_TRANSLATED are not set unless some real PATH_INFO
9575 came in with the request, for NCSA bug-compatibility. [Robert Thau]
9577 *) Don't leak the DIR * on HEAD request for a directory. [Robert Thau]
9579 *) Deleted the block_alarms() stuff from dbm_auth; no longer necessary,
9580 as timeouts are not in scope. [Robert Thau]
9582 *) quoted-string args in config files now handled correctly (doesn't drop
9583 the last character). [Robert Thau; reported by Randy Terbush]
9585 *) Fixed silly typo in http_main.c which was suddenly fatal in HP-UX.
9586 How the hell did it ever work? [Robert Thau; reported by Rob Hartill]
9588 *) mod_core.c --- default_type returns DEFAULT_TYPE (the compile-time
9589 default default type); the former default default behavior when all
9590 type-checkers defaulted had been a core dump. [Paul Sutton]
9592 *) Copy filenames out of the struct dirent when indexing
9593 directories. (On Linux, readdir() returns a pointer to the same
9594 memory area every time). Fix is in mod_dir.c. [Paul Sutton]
9596 Changes with Shambhala 0.5.3 [not released]
9598 *) Default response handler notes "file not found" in the error log,
9599 if the file was not found. [Cliff Skolnick].
9601 *) Another Cliff bug --- "GET /~user" now properly redirects (the userdir
9602 code no longer sets up bogus PATH_INFO which fakes out the directory
9603 handler). [Cliff Skolnick]
9605 Changes with Shambhala 0.5.2 06 Jul 1995
9607 *) Changes to http_main.c --- root server no longer plays silly
9608 games with SIGCHLD, and so now detects and replaces dying
9609 children. Child processes just die on SIGTERM, without taking
9610 the whole process group with them. Potential problem --- if any
9611 child process refuses to die, we hang in restart.
9612 MaxRequestsPerChild may still not work, but it certainly works
9613 better than it did before this! [Robert Thau]
9615 *) mod_dir.c bug fixes: ReadmeName and HeaderName
9616 work (or work better, at least); over-long description lines
9617 properly terminated. [Mark Cox]
9619 *) http_request.c now calls unescape_url() more places where it
9620 should [Paul Sutton].
9622 *) More directory handling bugs (reported by Cox)
9623 Parent Directory link is now set correctly. [Robert Thau]
9625 Changes with Shambhala 0.5.1 04 Jul 1995
9627 *) Generalized cleanup interface in alloc.c --- any function can be
9628 registered with alloc.c as a cleanup for a resource pool;
9629 tracking of files and file descriptors has been reimplemented in
9630 terms of this interface, so I can give it some sort of a test.
9633 *) More changes in alloc.c --- new cleanup_for_exec() function,
9634 which tracks down and closes all file descriptors which have been
9635 registered with the alloc.c machinery before the server exec()s a
9636 child process for CGI or <!--#exec-->. CGI children now get
9637 started with exactly three file descriptors open. Hopefully,
9638 this cures the problem Rob H. was having with overly persistent
9639 CGI connections. [Robert Thau]
9641 *) Mutual exclusion around the accept() in child_main() --- this is
9642 required on at least SGI, Solaris and Linux, and is #ifdef'ed in
9643 by default on those systems only (-DFCNTL_SERIALIZED_ACCEPT).
9644 This uses fcntl(F_SETLK,...) on the error log descriptor because
9645 flock() on that descriptor won't work on systems which have BSD
9646 flock() semantics, including (I think) Linux 1.3 and Solaris.
9648 This does work on SunOS (when the server is idle, only one
9649 process in the pool is waiting on accept()); it *ought* to work
9650 on the other systems. [Robert Thau]
9652 *) FreeBSD and BSDI portability tweaks [Chuck Murcko]
9654 *) sizeof(*sa_client) bugfix from [Rob Hartill]
9656 *) pstrdup(..., NULL) returns NULL, [Randy Terbush]
9658 *) block_alarms() to avoid leaking the DBM* in dbm auth (this should
9659 be unnecessary if I go to the revised timeout-handling scheme).
9662 *) For NCSA bug-compatibility, set QUERY_STRING env var (to a null
9663 string) even if none came in with the request. [Robert Thau]
9665 *) CHANGES file added to distribution ;-).
9667 Changes with Shambhala 0.4.5
9669 *) mod_dld --- early dynamic loading support [rst]
9670 *) Add wildcard content handlers for XBITHACK; default_hander now
9671 invoked with that mechanism (as a handler hanging off mod_core) [rst]
9672 *) XBITHACK supported as a wildcard content-handler, and
9673 configurable at run-time (not just at compile time, as in the
9674 "patchy server" releases) [rst]
9676 Changes with Shambhala 0.4.4 30 Jun 1995
9678 *) Fixed basic thinkos in mod_dbm_auth.c [rst, reported by Mark Cox]
9679 *) Handle Addtype x/y .z [rst, reported by Cox]
9681 Changes with Shambhala 0.4.3
9683 *) Fixed very dumb bug in mod_alias; "Alias" and "Redirect" are not
9684 synonymous [rst, terbush]
9686 Changes with Shambhala 0.4.1 28 Jun 1995
9688 *) First-cut virtual host implementation; some refit in the config
9689 reading code, and log management, was necessary to support this [rst]
9690 *) Sub-pool machinery, originally added to avoid excessive storage
9691 allocation on listings of large directories (which turned out to
9692 be the problem that the 0.3 storage accounting was added to
9693 find). Subrequests and mod_dir changed to use subpools. [rst]
9694 *) More memory debugging --- free list consistency checks. [rst]
9695 *) Added err_headers to request_rec, with support elsewhere [rst]
9696 *) Other fixes to minor bugs in mod_dir and mod_includes [rst, terbush]
9698 Changes with Shambhala 0.3 19 Jun 1995
9700 *) Switch ONE_PROCESS to a runtime command-line option (-X)
9701 *) Don't compile in mod_ai_backcompat by default
9702 *) Switch name of server from Apache to Shambhala in Makefile
9703 *) Add some accounting routines to track memory usage in the pools,
9706 Changes with Shambhala 0.2
9708 *) Set DOCUMENT_ROOT CGI variable
9709 *) Add single-process debugging, as a compile-time option (ONE_PROCESS)
9710 *) Add critical section protection to handling of cleanup structures
9712 *) Significant code reorg within the server core to group related
9713 functions together [rst]
9714 *) Correctly handle clients that hang up before sending any request
9716 *) Replace dying child processes. [rst]
9718 Changes with Shambhala 0.1 12 Jun 1995
9720 Major rewrite of the pre-existing "patchy server" codebase, by
9721 Robert Thau (rst). Significant portions of the server code, such
9722 as configuration-file handling and HTTP authentication support,
9723 were ripped out and rewritten from scratch. Code that was not
9724 completely rewritten was significantly altered.
9726 Major changes with this release include:
9728 *) Introduction of the module API; in request handling, the central
9729 machinery just dispatches to various modules, which actually do
9730 most of the work. Configuration handling is similar --- modules
9731 declare their own commands, and the central machinery just
9734 API features from shambhala/0.1 were substantially unchanged in
9735 Apache 1.0 and 1.1. (1.0 API features not yet present in this
9736 release, such as wildcard handlers and subpools, were added in
9737 subsequent Shambhala releases, and were also generally rst's
9740 *) This release included the following modules:
9742 mod_access (access control --- allow and deny directives),
9743 mod_alias (Alias and Redirect commands),
9744 mod_auth (straight HTTP authentication, based on flat-files)
9745 mod_auth_dbm (same, with dbm files)
9746 mod_cgi (CGI scripts and, in this release, ScriptAlias)
9747 mod_common_log (CLF access logs; later renamed mod_log_common)
9748 mod_dir (directory indexing)
9749 mod_include (server-side includes)
9750 mod_mime (AddType directives)
9751 mod_negotiation (content negotiation)
9752 mod_userdir (support for users' public_html directories)
9754 It also included a mod_ai_backcompat, which was a private hack
9755 for back-compatibility with rst's own AI-lab servers.
9757 All of these modules were substantially complete, and functional
9758 or nearly so (a few, which implemented features not in use at
9759 Thau's site, required patches of a few lines).
9761 *) sub-request machinery, to allow modules to determine how other
9762 modules would assign MIME types to a given file, or optionally
9763 serve its content (this is heavily used by mod_dir, mod_include
9764 and mod_negotiation).
9766 *) Resource pool system for keeping track of memory allocated and
9767 files opened in service of a particular request. Much of the
9768 code in the modules (when they weren't rewrites) was adjusted to
9769 replace a pervasive convention of using fixed-size buffers on
9770 the stack with an equally pervasive convention of using memory
9771 allocated with palloc().
9773 *) Reorganization of data structures associated with a given
9774 request to eliminate use of global variables and the troublesome
9775 unmunge_name function (used in NCSA and early Apache releases to
9776 attempt to determine the URI which mapped to a given filename
9777 --- a difficult proposition, given that it is easy to produce
9778 setups in which multiple URIs map to the same file).
9780 *) Source files renamed and rearranged
9782 *) Very simple pre-forking behavior --- parent process forked off a
9783 fixed number of children, and then just waited for SIGHUP.
9785 *) Other more minor changes too numerous to list.
9787 This release included modified versions of a lot of code from the
9788 Apache 0.6.4 public release, plus an early pre-forking patch
9789 codeveloped by Robert Thau and Rob Hartill.
9791 Changes with Apache 0.7.3 20 Jun 1995
9793 *) There were a bunch of changes between Apache 0.6.4 and 0.7.3 that
9794 were incorporated by Rob Hartill on the main branch while Robert Thau
9795 worked on the Shambhala rewrite above. Most were merged into the
9796 Shambala architecture after Apache 0.8.0.
